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

1093 and server and core library. Protocol TODO #23. Affected
1094 files are lib/silccore/silcmode.h, silcd/server.[ch],
1095 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
1096 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
1098 * Added new channel user mode BLOCK_MESSAGES which the client
1099 may set to itself to tell server not send channel messages.
1100 Other packets such as channel key packets are still sent.
1101 Protocol TODO #23. Updated the protocol specs, client and
1102 server. Affected files are lib/silccore/silcmode.h,
1103 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1104 lib/silcutil/silcutil.c, silcd/command.c, and
1105 silcd/packet_send.c.
1107 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Redefined the Status Payload to include now two 8 bit fields,
1110 instead of one 16 bit field. This now makes it possible to
1111 send list of errors. Updated the protocol specs and the code
1112 in core library, client library and server. Protocol TODO #1.
1113 Affected files are lib/silccore/silccommand.[ch],
1114 lib/silcclient/command_reply.[ch], silcd/command.c,
1115 silcd/command_reply.c and silcd/packet_receive.[ch].
1117 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1119 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1120 must be handled by the application and should tell the application
1121 that an error message was already printed, and it should print the
1122 config coords (line, filename, ...). Affected files are
1123 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1125 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1126 server config parsing code more readable.
1128 Fixed a bug in the fetch_logging() config callback.
1130 Affected files is silcd/serverconfig.c.
1132 * Drop root privileges when started in foreground. Don't drop them
1133 if debugging also. Affected file is silcd/silcd.c.
1135 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1137 * Added more IM-like features by introducing new user modes
1138 for setting various presence information. Added new modes:
1139 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1140 specs and code. Protocol TODO #19. Affected files are
1141 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1142 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1144 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1146 * Added STATS command to the protocol after all, to return
1147 various statistical information about the network. It can
1148 be used by clients to retrieve statistical information, and
1149 servers may use it to to fetch cell and network wide
1150 statistics from router. Updated the protocol specs and
1151 implemented it to the server. Protocol TODO #16.
1152 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1153 silcd/command_reply.[ch].
1155 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * The LIST command reply in client libary now adds new channel
1158 entry if the returned channel doesn't exist yet in cache,
1159 and returns the channel entry to the application in the
1160 command_reply client operation. Affected file is
1161 lib/silcclient/command_reply.c.
1163 * Changed the channel message payload's MAC generation to
1164 include the IV in the MAC as well. This way all relevant
1165 parts of the channel message payload are authenticated also
1166 with the channel message MAC (and not only by packet MAC).
1167 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1168 Affected file is lib/silccore/silcchannel.c.
1170 * Fixed the SKE to save the remote version, since the
1171 silc_ske_parse_version mistakenly checked wrong version,
1172 after it replaced the start payload. Affected files are
1173 lib/silcske/silcske.[ch].
1175 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1178 string utility functions. Added there also new functions
1179 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1180 Affected files lib/silcutil/silcstrutil.[ch].
1182 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1183 files are lib/silcutil/silcstrutil.[ch].
1185 * Defined that the security property fields in SKE SHOULD be
1186 UTF-8 encoded, defined that version string MUST be US-ASCII
1187 encoded, defined that passphrases sent in connection
1188 authentication protocol MUST be UTF-8 encoded. Implemented
1189 these to the client and server. Defined also that other
1190 passphrases sent in the protocol MUST be UTF-8 encoded.
1191 Affected files are lib/silcske/silcske.c,
1192 lib/silcclient/protocol.c, silcd/protocol.c,
1193 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1195 * Changed the silc_client_close_connection interface to not
1196 need the SilcSocketConnection which should not be visible
1197 to application. Affected files are lib/silcclient/client.c
1198 and lib/silcclient/silcclient.h.
1200 * Rewrote the text for Private Message Key Payload in the
1201 protocol specification. Protocol TODO #11.
1203 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1205 * Upgraded the protocol version to 1.1, updated protocol specs
1208 * Added the nickname as new argument to NICK_CHANGE notify and
1209 added it to protocol specs and implemented it to client and
1210 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1211 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1212 lib/silcclient/client_notify.c.
1214 * Added the killer's client ID to the KILLED notify and added
1215 it to protocol specs and implemented it to client and server.
1216 Protocol TODO #13. Affected files are silcd/command.c,
1217 silcd/packet_receive.c, packet_send.[ch],
1218 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1219 The killer's client entry is now returned to application in
1220 the `notify' client operation.
1222 * Fixed the Max Argument fields that had too large value set
1223 in the protocol specs. Protocol TODO #14.
1225 * Added the LEAVE command reply to return the ID of parted
1226 channel. Updated protocol specs and implemented it to the
1227 client and server. Protocol TODO #15. Affected files are
1228 silcd/command.c, lib/silcclient/command_reply.c. The channel
1229 entry is now returned to application in the `command_reply'
1232 * Rewrote the version SKE version checking in client libary
1233 and in server to use the silc_parse_version_string. Affected
1234 files are lib/silcclient/protocol.c, silcd/protocol.c.
1236 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1237 commands that was missing it, and updated protocol specs and
1238 the server implementation. Protocol TODO #10. The affected
1239 file is silcd/command.c.
1241 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1242 generic reply to a generic request (REQUEST flag), and
1243 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1244 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1245 to define the payload for DATA flag. Added the flags to
1246 the implementation. Protocol TODO #9. Affected file is
1247 lib/silccore/silcchannel.h.
1249 Changed the client library to return the message length
1250 to application as well in the channel_message and private_message
1251 client operations. Affected files are
1252 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1253 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1254 and lib/silcclient/client_ops_example.c.
1256 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1257 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1258 the channel. Updated protocol specs and impelemented this
1259 to client and server. Protocol TODO #6. Affected files are
1260 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1261 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1263 Added new options m and M to CMODE command in Irssi SILC
1264 client to set these modes.
1266 * Deprecated all administrative commands from SILC protocol
1267 since they are highly implementation specific commands.
1268 Updated protocol specs. Moved the old commands in
1269 implementations to private range of command types. Affected
1270 files are silcd/command.c, lib/silcclient/command.c and
1271 lib/silcclient/command_reply.c. Protocol TODO #8.
1273 * Fixed a bug in server where sending unknown command crashes
1274 the server. Affected file silcd/command.c.
1276 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1278 * Added SILC_PROTOCOLVERSION macro to check protocol version
1279 of a socket connection. The affected file is
1280 lib/silcutil/silcsockconn.h.
1282 * Added better error logging in rekey protocol. Affected file
1285 * Do not check public key types in SKE during rekey. Affected
1286 file lib/silcske/payload.c.
1288 * Fixed the rekey protocol with PFS, which was totally broken.
1289 Affected file silcd/protocol.c.
1291 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1293 * Some client implementations quit network by doing first LEAVE
1294 and then immediately SIGNOFF (like Bombyx). We now do check
1295 after a short time after LEAVE notify and check whether the
1296 client is still valid after LEAVE, and if not we remove it from
1297 cache. Affected file is lib/silcclient/client_notify.c.
1299 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1301 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1302 it's good not to have security holes here.
1304 * Fixed a negative refcount situtuation for the config context.
1305 Affected file is silcd/serverconfig.c.
1307 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1309 * ROBOdoc documented lib/silcutil/silcutil.h.
1311 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1313 * Optimized even more the SilcPacketContext structure. Now
1314 totally saved 16 bytes of memory per context after optimization.
1315 Affected files are lib/silccore/silcpacket.[ch].
1317 * Made strict checks for valid SILC IDs. Affected file is
1318 lib/silccore/silcid.c.
1320 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * Changed the object argument for silc_cipher_register,
1323 silc_hash_register, silc_hmac_register and silc_pkcs_register
1324 to const. Affected files are lib/silccrypt/silccipher.[ch],
1325 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1327 * Changed the silc_get_username and silc_get_real_name to
1328 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1330 * Fixed the Irssi SILC Client to use the silc_get_username and
1331 silc_get_real_name insted of glib routines since the glib
1332 routines only corrupt stack. Fixes the Irssi SILC to work in
1333 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1335 * Fixed the Irssi to not use g_get_home_dir since it crashes
1336 or returns garbage on cygwin and corrupts stack. Added function
1337 get_home_dir to Irssi routines. Affected files are
1338 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1340 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Made some structure optimizations. SFTP memory FS MemFSEntry
1343 entry structure. Optimized SilcTask structure. Optimized
1344 SilcPacketContext structure.
1346 Affected files lib/silcsftp/sftp_fs_memory.c,
1347 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1349 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1351 * And yet again reverted back the config thing since Johnny
1352 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1355 * Fixed memory leaks from config object. Affected files are
1356 silcd/serverconfig.[ch].
1358 * Added support for adding new connections to the server in rehash.
1359 After rehash they take effect.
1361 Added support for changing the maximum allowed connections in
1362 rehash. The number can grow but going smaller is not supported.
1364 Added function silc_server_num_sockets_by_remote to the
1365 silcd/server_util.[ch].
1367 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1369 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1371 * Added preliminary checking during config parsing for a valid
1372 public/private key and removed further checks in the code.
1373 Affected files are silcd/serverconfig.[ch], server.c.
1375 * Moved functions silc_server_drop() and silc_server_daemonise()
1376 from server.c to silcd.c since they are stricly related to
1377 the application activity.
1379 * Reverted a small part of the automatic ref/unref since
1380 it caused a double unref in some situations. Affected
1381 files are silcd/silcd.[ch], server.c, serverconfig.c.
1383 * Added some .cvsignore files in the lib directory.
1385 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1387 * Fixed silc_net_gethostbyaddr to correctly resolve by
1388 address. Affected file lib/silcutil/silcnet.c.
1390 * Fixed the notify relaying to client. The HMAC to be used
1391 with relayed packets ws wrong and caused decryption failure
1392 at the client end. Affected file is silcd/packet_receive.c.
1394 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1396 * Created new branch silc_protocol_1_0_branch.
1398 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1400 * Changed the silc_server_config_* routines to be SilcServer
1401 independent. They are now officially application specific code
1402 and not part of generic server implementation. Affected files
1403 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1405 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1407 * Added automatic referencing of config context in the
1408 silc_server_config_alloc, and automatic unreferencing in the
1409 silc_server_config_destroy. Affected files are
1410 silcd/serverconfig.[ch], silcd/silcd.c.
1412 * Fixed the silc_log_quick handling in the logging routines.
1413 It didn't log quickly when it was TRUE. Affected file is
1414 lib/silcutil/silclog.c. Also the flush delay was set even
1415 if it was 0 in config file. Affected file is
1416 silcd/serverconfig.c.
1418 * Added support for changing key pair of the server in rehash.
1419 Affected file silcd/server.c.
1421 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1423 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1424 too early, before getting the channel entry. Affected file
1425 is silcd/packet_receive.c.
1427 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1429 * Added functions silc_server_config_[ref/unref], these are used
1430 to prevent that the config object is destroyed.
1432 No longer directly affect global variables silc_log_quick and
1433 silc_log_delay, they are first cached inside the config object
1434 and then applied with silc_server_config_setlogfiles().
1436 silc_server_config_set_defaults() is now internal to
1437 serverconfig.c, there are no reasons to show this internal stuff
1440 Affected files are silcd/serverconfig.[ch].
1442 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1443 fprintf's to stderr, since some code may be executed again after
1444 the server went into the background. Affected files are
1447 * Added rehash support. Added function silc_server_rehash() that
1448 will perform all the basic tasks of the rehashing procedure.
1450 * Added command line option `-x, --hexdump'. This will enable the
1451 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1452 The option `--hexdump' implies `--debug'.
1454 * Fixed a bad bug in the logging APIs (silcutil library) where
1455 the application would crash after calling silc_log_reset_all().
1457 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed the KICKED notify handling in client library to
1460 correctly remove the channel and all entries from the
1461 channel when I was kicked. This bug crashed the client.
1463 Fixed yet another but in KICKED notify handling to remove
1464 the kicked client correctly from the channel.
1466 Affected file is lib/silcclient/client_notify.c.
1468 * Fixed a minor bug in looking up correct client entry
1469 in KICKED notify in server. Affected file is
1470 silcd/packet_receive.c.
1472 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1473 sources correctly to distribution. Fixes --with-gmp option.
1475 * Removed the manual rehashing from ID Cache, and changed it
1476 to use the SILC Hash Table's auto rehash feature. Affected
1477 file is lib/silccore/silcidcache.c.
1479 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1481 * Fixed a bug in the silc_client_nickname_format function that
1482 handles the multiple same nickname formatting. Two clients
1483 with same nickname caused problems after the first one left
1484 and rejoined. It didn't format the nickname correctly.
1485 Affected file is lib/silcclient/idlist.c.
1487 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Don't change the topic if olod topic is same as new one.
1490 Affected file is silcd/packet_receive.c.
1492 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1494 * Added cross-reference support to the SILC Documentation
1495 generator. All types across all HTML files are now cross-
1496 referenced. Affected files util/robodoc/generator.c and
1497 scripts/silcdoc/silcdoc.
1499 * Added file lib/silcutil/silctypes.h to include all the
1500 arithmetic type definitions and some macros. Removed
1501 includes/bitmove.h and moved macros to silctypes.h.
1503 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1509 * Added `type' argument to silc_id_payload_parse_id function which
1510 now returns the type of the ID to the sent pointer. Affected
1511 file is lib/silccore/silcid.[ch].
1513 * Added check for CMODE_CHANGE notify type that mode change is
1514 allowed by the sender. Affected file silcd/packet_receive.c.
1516 * Added check for CUMODE_CHANGE notify type that mode change is
1517 allowed by the sender. Affected file silcd/packet_receive.c.
1518 Added the ID type as CUMODE_CHANGE notify type as argument
1519 to the `notify' client operation. Affected files are
1520 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1522 * Added function silc_client_add_server to the client library.
1523 Added support for resolving also channel and server info when
1524 received unknown entity in notify packet. Affected files are
1525 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1527 * Added function silc_command_get_status to return the command
1528 status from the command reply's argument payload. Affected files
1529 are lib/silccore/silccommand.[ch].
1531 * Added check for KICKED notify type that the kicking is
1532 allowed by the client. Affected file silcd/packet_receive.c.
1534 * Created function silc_get_input which can be used to get input
1535 (echo on or off) from user on command line. Affected files are
1536 lib/silcutil/silcutil.[ch].
1538 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1540 * Optimized silc_server_packet_relay_to_channel function.
1541 Added new function silc_channel_message_payload_encrypt which
1542 can be called directly if channel message payload needs to
1543 be encrypted and is already encoded (no need to call _encode
1544 function). Packet relaying is now done by router without any
1545 extra memory allocations. Affected files are
1546 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1547 silcd/packet_send.c.

1567 by the client. Affected files are silcd/server_util.[ch],
1568 silcd/packet_receive.c and silcd/command.c.
1570 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1573 ID length. It ignored that ID can be IPv6 based as well.
1574 Affected file lib/silccore/silcpacket.h.
1576 * Fixed the silc_id_id2str and silc_id_str2id to take the
1577 IPv6 address offset's into consideration. Affecte file is

1583 NULL context they may receive. The affected file is
1584 lib/silcutil/unix/silcunixschedule.c.
1586 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1588 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1589 can specify different directory with --home command line
1590 parameter. Affected files irssi/src/silc/core/client_ops.c,
1593 * SILC-specific commands aren't now executed if the active server
1594 isn't of SILC-type, so there won't be problems with having
1595 IRC and SILC protocol support in same client. Affected files
1596 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1599 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1601 * Improved the signal support in SILC Schedule. Added new
1602 function silc_schedule_signal_call which is used by application
1603 to mark a signal to be called. It is now safe to perform
1604 any kind of tasks in signal callbacks since it is guaranteed
1605 that the application specified signal callback is called
1606 after the signal is over. Affected files are
1607 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1609 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Added `name' field to SilcChannelPrivateKey to represent
1612 application given name for the key. Moved also the context from
1613 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1614 Added the `name' argument also to the function
1615 silc_client_add_channel_private_key.
1617 Added function silc_client_current_channel_private_key to set the
1618 current channel private key in use.
1620 Added "change" command to KEY command which can be used to change
1621 the current channel private key. Bound the command also to
1622 alt+K (Alt+Shift+k).
1624 Also affected files lib/silcclient/client_channel.c,
1625 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1627 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * Added silc_rng_get_byte_fast function in to the
1630 lib/silccrypt/silcrng.[ch].
1632 * Changed the interface of silc_packet_assemble and the
1633 silc_packet_send_prepare. If silc_packet_assmble is now
1634 called the application does not call silc_packet_send_prepare
1635 because the library will call it automatically. These
1636 interfaces now also return a reference to the outgoing buffer
1637 which includes the assembled packet, which the application can
1638 use to encrypt the packet.
1640 Affected files are lib/silccore/silcpacket.[ch],
1641 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1642 silcd/packet_send.c, server_backup.c and packet_receive.c.
1644 * Fixed a packet sending bug on very high load, where outgoing
1645 packet queue wasn't handled correctly and packets got corrupted.
1646 Affected files are lib/silcutil/*/silc*sockconn.c,
1647 lib/silcclient/client.c and silcd/server.c.
1649 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1651 * Added macro SILC_PACKET_DATALEN which can be used during
1652 packet assembling to check whether the data to be added to
1653 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1654 len is truncated until it fits it.
1656 Added checks for maximum length of channel message payload and
1657 private message payload also.
1659 Added checks for maximum packet length in server and in
1662 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1663 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1664 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1665 lib/silcclient/client_prvmsg.c.
1667 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1669 * Added silc_server_packet_queue_purge call to the
1670 silc_server_disconnect_remote to assure that all data in the
1671 queue before disconnecting is sent to the network. Affected
1672 file silcd/server.c.
1674 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1676 * Added the deleting of server's own ID cache entry to the
1677 silc_server_free function. Free also everything else that
1678 has been allocated in silc_server_init. The affected file
1681 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1683 * Added functions silc_parse_version_string, silc_version_to_num,
1684 and silc_ske_parse_version to parse SILC protocol style version
1685 strings. Affected files lib/silcutil/silcutil.[ch] and
1686 lib/silcske/silcske.[ch].
1688 * Added new configuration params: version_protocol, version_software
1689 and version_software_vendor to specify what version the remote
1690 host must at least be to be able to connect to server. The vendor
1691 string can be regex matched too. Added new function
1692 silc_server_connection_allowed to check maximum number of allowed
1693 connections, and allowed versions for incoming connections.
1694 Affected files are silcd/server.c, server_util.[ch] and
1697 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Added preliminary support for signals in scheduler. The
1700 signals we care about are now blocked always when the scheduler
1701 is locked. This way we can synchronise the use of signal with
1702 scheduler. It is guaranteed that when signal occurs the scheduler
1703 is not locked, and thus new tasks can be safely added to the
1706 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1707 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1708 Added new platform specific routines
1709 silc_schedule_internal_signals_[un]block and
1710 silc_schedule_internal_signal_[un]register.
1712 Added new functions to SILC Schedule API:
1713 silc_schedule_signal_[un]register. Each signal that application
1714 is going to use should be registered to the scheduler.
1716 Affected files are lib/silcutil/silcschedule.[ch],
1717 lib/silcutil/*/silc*schedule.c.
1719 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Check for unauthenticated client and server in the
1722 silc_server_new_client and silc_server_new_server functions.
1723 Affected file silcd/packet_receive.c.
1725 * Added function silc_string_is_ascii to check whether given
1726 string is 7-bit ASCII string. Affected files are
1727 lib/silcutil/silcutil.[ch].
1729 * Added function silc_id_is_valid_server_id into the
1730 silcd/serverid.c and added checking for valid Server ID's in
1731 silc_server_new_server. The Server ID must always be based
1732 on the server's public IP address.
1734 * Added logging of DISCONNECT packet message in the server.
1735 Affected file silcd/server.c.
1737 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1739 * Changed all library interfaces that use Global RNG to also
1740 accept SilcRng as argument. Affected files are
1741 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1742 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1743 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1744 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1745 lib/silccrypt/rsa.c.
1747 * Added function silc_pkcs_generate_key to the
1748 lib/silccrypt/silcpkcs.[ch] for applications so that they
1749 don't need to do pkcs->pkcs->init calls anymore.
1751 * Remove SilcSocketConnection from the SFTP API since it really
1752 wasn't needed there. The application has the information
1753 saved in its contexts anyway and the SFTP layer doesn't need
1754 know about it. Affected files lib/silcsft/silcsftp.h and
1755 lib/silcsftp/sftp_[server/client].c.
1757 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1758 The SilcSimContext is not SilcSim.
1760 * Fixed possible buffer overflows in silc_id_render in the
1761 lib/silcutil/silcutil.c.
1763 * On EPOC the global crypto module lists are not used at all
1764 in the crypto library. Added support for using the constant
1765 algorithm list on EPOC. Affected files are
1766 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1769 * Fixed the handling of third parameter of KICKED notify, since
1770 it was mistakenly updated to SILC Protocol 1.0 even though it
1771 is to be included in 1.1. Since it is not in 1.0 it is not
1772 mandatory, and this fix now handles it only if it is provided,
1773 and it is not error if it is not provided. Affected file
1774 lib/silcclient/client_notify.c.
1776 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1778 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1779 client. Affected file irssi/src/silc/core/client_ops.c.
1781 * Merged with Irssi 0.8.4 from irssi.org CVS.
1783 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1785 * Check for valid socket connection in client entries before
1786 sending any messages. Fixes a crash, but doesn't fix some
1787 other underlaying bug that is lurking there. Affected
1788 file silcd/packet_send.c.
1790 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1792 * $usermode, $cumode and $cumode_space expandos shouldn't do
1793 anything with non-SILC server records. Affected file
1794 irssi/src/silc/core/silc-expandos.c
1796 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1798 * Fixed the silc_net_check_[host/local]_by_sock to support
1799 IPv6 bound sockets as well. Now they can return IPv6 addresses
1800 as well. Affected file lib/silcutil/silcnet.c.
1802 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1803 Affected lib/silcutil/unix/silcunixnet.c.
1805 * Fixed ID rendering (at least on some platforms, not NetBSD)
1806 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1808 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Added silc_hash_public_key and silc_hash_public_key_compare
1811 functions to be used with SilcHashTable. They can be used to
1812 hash public keys and compare public keys in hash table. Affected
1813 file lib/silcutil/silcutil.[ch].
1815 * Added support for specifying multiple public keys for Client
1816 connection section in server configuration file. This makes it
1817 possible to accept multiple public keys from same host, or to
1818 make a section that accepts any incoming host, and have the
1819 accepted public keys listed in the section.
1821 Added functions silc_sever_[find/get]_public_key, added the
1822 support for this actually to all connection sections but only
1823 the Client section is currently allowed to specify multiple
1826 Affected files are silcd/server.c, server_internal.h,
1827 command.c, protocol.c, server_util.[ch], packet_receive.c.
1829 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1831 * Merged Irssi 0.8.2 from irssi.org CVS.
1833 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1835 * If silc_debug is TRUE, also output standard logging messages
1836 to stderr with the debug output.
1838 Made silc_log_reset_all() flushing all channels before returning.
1839 Also fixed some documentation typos.
1841 Affected files are lib/silcutil/silclog.[ch].
1843 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1845 * Fixed the server to check correctly the amount of connections
1846 from single host, by checking also the type of the connection.
1847 Fixed also the comparison of number of connections and number
1848 of allowed connections. Affected files are silcd/server.c,
1851 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Fixed the USERS command reply to save the user's mode on the
1854 channel as well. Fixed JOIN command reply to check whether a
1855 client is on channel already and not join it twice. Affected
1856 file lib/silcclient/command_reply.c.
1858 * Added new file silc-expandos.c into irssi/silc/core/ to return
1859 various stuff for various signal for the statusbar etc. updating.
1860 Now Irssi SILC client prints channel user modes etc. on the
1863 * The user mode (like server/router operator changes) is now shown
1864 on the Irssi SILC client's statusbar. The affected files are
1865 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1867 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1869 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1870 to SILC_SCHEDULE_[UN]LOCK macros.
1872 * Added more error printing to logs in server code. Affected
1873 files silcd/server.c and silcd/protocol.c.
1875 * Fixed -S option parsing in Irssi SILC Client. Affected file
1876 irssi/src/silc/core/silc-core.c.
1878 * Added silc_buffer_alloc_size function. Affected file is
1879 lib/silcutil/silcbuffer.h.
1881 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1883 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1884 constants. Affected files in
1885 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1888 * Changed the internal SFTP Memory FS table to const. Affected
1889 file lib/silcsftp/sftp_fs_memory.c.
1891 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed the buffer formatting and unformatting routines to
1894 check the size of 64 bits types with sizeof(). Affected
1895 file is lib/silcutil/silcbuffmt.c.
1897 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1899 * Removed 0.6.x backwards support.
1901 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1903 * Changed all integer type names:
1904 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1905 to avoid collisions with other libraries using same type names
1908 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1910 * Added `prefer_ipv6' argument to the functions
1911 silc_net_gethostbyname[_async]. If it is TRUE it will return
1912 IPv6 address over IPv4. If FALSE IPv4 address is returned
1913 even if IPv6 address was found. Affected files
1914 lib/silcutil/silcnet.[ch].
1916 * Added support silc_net_create_connection[_async] to fallback
1917 to IPv4 address if IPv6 address could not be used (like if
1918 it doesn't work on a specific system). Affected file in
1919 lib/silcutil/unix/silcunixnet.c.
1921 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1923 * Added silc_schedule_reinit function to do the enlarging
1924 of the max tasks handling capabilities of the scheduler.
1925 Affected files lib/silcutil/silcschedule.[ch].
1927 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1929 * Added automatic extern "C" { ... } for C++ compilers so the
1930 application does not need to define them. Affected file
1931 includes/silcincludes.h.
1933 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1934 old name went against naming convention. Applications now
1935 include "silcclient.h" instead of "clientlibincludes.h".
1936 Removed includes/clientlibincludes.h, it is redundant now.
1938 * Renamed includes/version.h to silcversion.h.
1940 * Added really preliminary support for OS/2 into the util
1941 library. Only thread & mutex API is implemented, others
1942 are still to be implemented. Created the lib/silcutil/os2/
1943 directory. Created also file includes/silcos2.h.
1945 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1947 * Added preliminary BeOS support into the util library.
1948 Created lib/silcutil/beos/, and implemented all the needed
1949 functions to support SILC on BeOS. Created also file
1950 includes/silcbeos.h.
1952 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1954 * Added proper initializations to silc's irssi code, so it's
1955 now possible to load it as module. Affected files
1956 irssi/src/silc/core/silc-core.c,
1957 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1959 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1961 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1964 * Fixed the silcdoc document generator to correct generate
1965 docs from all kinds of filenames. Affected files are
1966 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1968 * ROBOdoc documented lib/silcutil/silcmemory.h.
1969 Added also new function silc_memdup.
1971 * Removed lib/silcutil/silcbufutil.h and moved those routines
1972 to the lib/silcutil/silcbuffer.h.
1974 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1976 * Added `user_count' to the SilcChannelEntry which now tells the
1977 number of users on the channel. The user count is now saved
1978 in normal server of global channels as well. Affected files
1979 silcd/server.c, idlist.h, packet_receive.c and command.c.
1981 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1982 include file utility functions.
1984 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1985 instead of calling directly OS routines.
1987 * Fixed NICK change printing in Irssi SILC Client. Fixed
1988 KICKED notify printing in Irssi SILC Client. Affected file
1989 irssi/src/silc/core/client_ops.c.
1991 * Fixed a NICK change bug in client library, to not recreate the
1992 client_entry->channels hash table everytime nick is changed.
1993 Affected file lib/silcclient/client.c.
1995 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1997 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1998 the SKE interface a bit.
2000 * Fixed padding problem in PKCS#1. The padding was not actually
2001 random since the random number generator was used incorrectly.
2002 This security bug affects only when encrypting with PKCS#1, and
2003 it is not currently used at all in SILC. SILC only use signing
2004 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2006 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2008 * Rewrote the notify handling in Irssi SILC client to not call
2009 the events as signals. Fixes problems with Perl support.
2010 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2012 * Send the auto-nicking NICK command in client library with
2013 little timeout after connecting. The affected file is
2014 lib/silcclient/client.c.
2016 * Added following new config file settings:
2017 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2018 key_exchange_timeout, conn_auth_timeout, connections_max,
2021 Implemented all the new config settings handling in the server.
2023 Optimized the use of SKE Mutual flag usage. Use it only
2024 if connection authentication protocol is not based in public
2027 Renamed all SilcServerConfigSection* to SilcServerConfig*
2028 to have a bit shorter names.
2030 Affected files silcd/serverconfig.[ch], server.[ch], and
2033 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2035 * Cleaned up the listening sockets code, preparing for the rehash
2036 support. Affected file is silcd/server.c.
2038 * Fixed some output messages. Affected files are silcd/silcd.c,
2041 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2043 * Create lib/doc/silcrng_intro.html document as introduction
2044 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2046 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2048 * Fixes to the silcd config template. Affected file is
2049 doc/example_silcd.conf.in.
2051 * Removed type casts from silc_calloc(), conforming to the
2052 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2054 * Removed param_name member from client, server, and router
2055 section structs, now identifying the param directly.
2057 Added CONFIG_FREE_AUTH macro in config file parsing.
2059 Affected files are silcd/serverconfig.[ch].
2061 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2063 * Fixed command line parameter handling. All SILC initialization
2064 is now done in silc_core_init() which also fixes autoconnecting
2067 Affected files irssi/src/silc/core/silc-core.c,
2068 irssi/src/fe-text/silc.c.
2070 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2072 * Added new configuration options and blocks:
2073 keepalive_secs, reconnect_count, reconnect_interval,
2074 reconnect_interval_max, reconnect_keep_trying and
2075 require_reverser_lookup. Added ConnectionParam block, and
2076 implemented the connection parameters when connecting as
2077 initiator and when accepting connections as responder.
2079 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2080 whether given configuration value has been given already.
2082 Affected files silcd/serverconfig.[c], server.[c].
2084 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2085 algorithm parts and created new file silcalgs.conf, that
2086 is now included from the example_silcd.conf.in.
2088 * Optimized the silc_server_connect_to_router_second to take
2089 the connection configuration object from the SilcServerConnection
2090 object instead of finding it during the connecting phase.
2091 Added the configuration object to SilcServerConnection struct.
2092 Affected files silcd/server_internal.h, server.c.
2094 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2096 * Add the client on channel after it was resolved at the
2097 channel message receiving, and it was not already on the
2098 channel. Affected file lib/silcclient/client_channel.c.
2100 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * Fixed the public key authentication to allocate always the

2108 * Unified the serverconfig.[ch]'s helper function interface.
2109 Affected file silcd/serverconfig.[ch].
2111 * Removed doc/example_silc.conf.in since it is redundant.
2112 The make install will now install irssi/silc.conf file.
2114 * Added new Passphrase and Publickey authentication methods to
2115 config file, allowing both public key and passphrase based
2116 authentication to be set at the same time.
2118 Added `prefer_passphrase_auth' setting in config file which
2119 can be used to set to prefer passwd auth if both passwd and
2120 public key is set. If not set, public key is preferred.
2121 This has effect only when being initiator (responder will try
2124 Added support for authentication with passphrase and public key
2125 at the same time. The passphrase is tried first always since
2126 it is faster to check.
2128 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2130 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2132 * Merged the new SILC Config library, with the server parsing
2133 support. Read the header file silcconfig.h or the toolkit
2134 documentation for the news. Affected files are

2143 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2145 * The silc_cipher_register, silc_hash_register and
2146 silc_hmac_register now checks if the object to be registered
2147 is registered already. Affected files are
2148 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2150 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2156 * Allow zero length channel messages inside the Channel Message
2157 Payload. Affected file lib/silccore/silcchannel.c.
2159 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2160 as header filenames.
2162 * Removed lib/silcclient/README and created HTML file
2163 lib/silcclient/silcclient_using.html, which is now included
2164 as part of Toolkit documentation.
2166 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2168 * Fixed CUMODE_CHANGE notify handling to change the mode of
2169 correct client. Affected file lib/silcclient/client_notify.c.
2171 * Make silc_rng_alloc fail if it cannot allocate the sha1
2172 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2174 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2176 * Fixed the file transfer's key agreement payload to include
2177 zero port also if the hostname is NULL because it could not
2180 Call file transfer monitor callback now also if error occurs
2181 during key agreement protocol.
2183 Changed the silc_client_file_send interface to return the
2184 SilcClientFileError instead of session id. The session ID
2185 is returned into pointer provided as argument.
2187 Check that the file exists locally before sending the
2188 file transfer request at all.
2190 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2192 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2193 error than can occur while key agreement protocol. Affected
2194 file lib/silcclient/silcapi.h.
2196 * Fixed the event_mode CMODE handler to not crash when mode
2197 is changed and +k mode is set in the channel. Affected file
2198 irssi/src/silc/core/silc-channels.c.
2200 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2201 SILC_LOG_WARNING to give out Warning and not Error. Affected
2202 file lib/silcutil/silclog.c.
2204 * Fixed the channel message payload decryption in the function
2205 silc_channel_message_payload_decrypt to not modify the original
2206 buffer before it is verified that the message decrypted
2207 correctly. Otherwise, next time it is called with correct
2208 channel key it won't encrypt since the payload is corrupted.
2209 Affected file lib/silccore/silcchannel.c.
2211 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2213 * Do not constantly resize the window. A fix patch by cras.
2214 Affected file irssi/src/fe-text/screen.c.

2219 Affected file lib/silcutil/silcnet.c.
2221 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2223 * Fixed a bug in hash table internal routine for traversing
2224 the table with foreach callback. The current entry may
2225 become invalid in the callback but it was referenced after
2226 the callback returned.
2228 Do not allow auto rehashing of hash table during the
2229 silc_hash_table_foreach operation, for same reasons as it is
2230 not allowed for SilcHashTableList. Affected files are
2231 lib/silcutil/silchashtable.[ch].
2233 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2235 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2236 Win32 DLL. extern's in header files are now declared with
2239 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2241 * Fixed private message handling. It used some old code that
2242 caused the client to crash. Affecte file is
2243 lib/silcclient/client_prvmsg.c.
2245 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2247 * Added function silc_client_add_channel,
2248 silc_client_replace_channel_id, and removed functions
2249 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2250 from client library.
2252 * Added cross reference of the joined channels to the
2253 SilcClientEntry, and changed the SilcChannelEntry's
2254 users list to SilcHashTable. The affected files are
2255 lib/silcclient/idlist.[ch].
2257 * Fixed a bug in hash table tarversing. While the hash table
2258 is traversed with SilcHashTableList the table must not be
2259 rehashed. It is now guaranteed that auto rehashable tables
2260 are not rehashed while tarversing the list. Also defined that
2261 silc_hash_table_rehash must not be called while tarversing
2262 the table. Added function silc_hash_table_list_reset that must
2263 be called after the tarversing is over. The affected files are
2264 lib/silcutil/silchashtable.[ch].
2266 * Changed all hash table traversing to call the new
2267 silc_hash_table_list_reset in server and in client library.
2269 * Added function silc_client_on_channel to return the
2270 SilcChannelUser entry if the specified client entry is joined
2271 on the specified channel. This is exported to application as
2272 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2274 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2276 * Fixed founder regaining problem with JOIN command on normal
2277 server. The notify for mode change must be sent always and
2278 not only if !cmd->pending. Affected file silcd/command.c.
2280 * Fixed the WHOWAS command's reply sending to support the
2281 lists correctly. Affected file silcd/command.c.
2283 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2285 * When sending JOIN command to router for processing the
2286 sender's old command identifier was not saved back to the
2287 sender's command context, fixed now. The affected file is
2290 * Create the key in JOIN command of the router did not return
2291 the channel key, added check for this. Affected file is
2294 * Fixed a channel ID update bug in JOIN command reply. Do
2295 not directly upgrade the ID but call the function
2296 silc_idlist_replace_channel_id if the ID was changed.
2297 Affected file silcd/command_reply.c.
2299 * Fixed memory leaks from command calling if it would fail.
2300 Affected file silcd/command.c.
2302 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2304 * Applied patches from cras:
2306 Memory leak fixes around libaries, irssi window resize fix,
2307 new silclist.h and silcdlist.h, all extern inline changed to
2310 * Removed dotconf from lib/dotconf, not needed anymore.
2312 * Removed TRQ from lib/trq, not needed anymore.
2314 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2315 with server connections. Later this will be configurable
2316 in config file after new config file is done. Affected file
2319 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2321 * Fixed a crash in server related to channel announcements.
2322 Affected file silcd/server.c.
2324 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed memory leaks in silc_server_create_new_channel*
2327 functions. Affected file silcd/server.c.
2329 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2330 which ID was changed. This way the router will send the
2331 user list for the channel again, and server won't be in
2332 desync in some rare circumstances. Affected file is
2333 silcd/packet_receive.c.
2335 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2337 * Check for NULL socket pointer in the function
2338 silc_server_packet_send_to_channel_real. Affected file
2339 silcd/packet_send.c.

2342 list. Affected file silcd/packet_receive.c.
2344 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2346 * Fixed some header addition to Toolkit distribution in
2347 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2349 * Added lib/silcclient/client_ops_example.h as an template
2350 file for application programmers to quickly start using
2351 the SilcClientOperation functions in their application.
2352 Updated the lib/silcclient/README as well to tell about this
2353 nice file made available.
2355 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2357 * Call silc_server_remove_from_channels when removing client
2358 entry when NO_SUCH_CLIENT_ID was received. Affected file
2359 is silcd/command_reply.c.
2361 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Added server & router operator statistics updating. Affected
2364 file silcd/packet_receive.c and silcd/command.c.
2366 * Fixed the SERVER_SIGNOFF notify handling on normal server
2367 not to save the history information for clients. Same was
2368 fixed earlier in remove_clients_by_server function, but not
2369 here. Affected file silcd/packet_receive.c.
2371 * Raised the default connection-retry count from 4 to 7 in
2372 server. Affected file silcd/server.h.
2374 * Cancel any possible reconnect timeouts when we start the
2375 key exchange. Affected file silcd/server.c.
2377 * Do not reconnect on connection failure when SCONNECT was
2378 given. Affected files silcd/server.[ch].
2380 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2382 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2384 * Fixed the NICK command to always give the unformatted
2385 nickname to the one giving the NICK command. If unformatted
2386 nickname is cached already it will be formatted and the
2387 local entry will always get the unformatted nickname.
2388 Affected file lib/silcclient/idlist.c.
2390 * Fixed some double frees from client library commands.
2391 Affected file is lib/silcclient/command.c.
2393 * Fixed CUMODE command in server to assure that no one can
2394 change founder's mode than the founder itself, there was a
2395 little bug. Affected file silcd/command.c.
2397 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2399 * Removed the SilcClientCommandDestructor from the client
2400 libary, it is not needed anymore. Affected files are
2401 lib/silcclient/silcapi.h, command[_reply].[ch],
2402 client_notify, idlist.c.
2404 * Fixed GETKEY command to first resolve client, and then
2405 resolve the server only if the client was not found, instead
2406 of resolving both at the same time. Affected file is
2407 lib/silcclient/command.c.
2409 * Added silc_client_start_key_exchange_cb and lookup the
2410 remote hostname and IP address before starting the key
2411 exchange with server. The affected file is
2412 lib/silcclient/client.c.
2414 * The server's public key is now saved using the IP address
2415 of the server and not the servername for the filename.
2416 The hostname public key filename is checked as an fall back
2417 method if the IP address based filename is not found.
2419 Fixed the GETKEY command to save the fetched server key
2420 in correct filename.
2422 Print the remote server's hostname now when new key is
2423 received during connection process. Affected file is
2424 irssi/src/silc/core/client_ops.c.
2426 * Return always our own public key to the client if it asks
2427 for it with GETKEY command. Affected file silcd/command.c.
2429 * Removed the use_auto_addr variable from default config
2430 file since it was in wrong section. Affected file is
2433 * Fixed TOPIC_CHANGE notification to not route it when it
2434 was sent using silc_server_send_notify_to_channel function.
2435 Affected file silcd/command.c.
2437 * Fixed silc_server_send_notify_kicked to send the kicker's
2438 Client ID also, it was missing. Affected files are
2439 silcd/command.c, silcd/packet_send.[ch].
2441 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2443 * Do not save client history information in SERVER_SIGNOFF.
2444 Fixes the bug in normal server that it does not detect
2445 the client becoming valid after the server becomes back
2446 online. Affected file silcd/server_util.c.
2448 * Added `sock_error' field into the SilcSocketConnection
2449 context. When error occurs during socket operation (read
2450 or write) the error is saved. Added also new function
2451 silc_socket_get_error to return human readable socket error
2452 message. Affected files are lib/silcutil/silcsockconn.[ch],
2453 lib/silcutil/unix/silcunixsockconn.c, and
2454 lib/silcutil/win32/silcwin32sockconn.c.
2456 * The server now prints the socket error message in the
2457 signoff for client. Affected file silcd/server.c.
2459 * Fixed the `created' channel information sending from router
2460 to server in JOIN command. Checks now whether the channel
2461 really was created or not and set it according that.
2463 Fixed the JOIN command to use the client entry's current
2464 ID during the joining procedure instead of the one it sent
2465 in the command (it is checked though), since it can change
2466 between the packet processing and command processing, and
2467 would just case unnecessary pain in the client end. Affected
2468 file silcd/command.c.
2470 * Fixed a channel key payload sending to use correct channel
2471 ID when the server was forced to change the channel's ID by
2472 router. Router sent the key payload with the old Channel ID.
2473 Affected file silcd/packet_receive.c.
2475 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2477 * Call silc_server_save_channel_key only if the key payload
2478 was provided in the JOIN command's command reply. Affected
2479 file silcd/command_reply.c.
2481 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2483 * Fixed silc_mp_sizeinbase to return the value correctly with
2484 MPI. Affected file lib/silcmath/mp_mpi.c.
2486 * Fixed the stop_server signal to correctly stop the scheduler
2487 and gracefully stop the server when SIGTERM or SIGINT signals
2488 are received. Affected file silcd/silcd.c.
2490 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2492 * Simple handling of TERM and HUP signals. Also added some log
2493 flushing call around. Affected file is
2496 * Fixed small bugs in silclog.c. Now buffering output will take
2497 effect after 10 seconds since startup: This will ensure that
2498 no important startup messages are lost. Also output redirection
2499 will preserve original format ([Date] [Type] message).
2500 Affected file is lib/silcutil/silclog.c.
2502 * Added two options to the config file, in the logging section:
2503 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2504 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2506 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2508 * Do not print the warning about log files not being initialized
2509 more than once to avoid excess logging. Affected file is
2510 lib/silcutil/silclog.c.
2512 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2513 the SIM copying in make install in Makefile.am.pre.
2515 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2517 * Rewritten silclog APIs. Globally interesting changes follows:
2518 silc_log_set_files() changed to silc_log_set_file().
2519 silc_log_set_callbacks() changed to silc_log_set_callback().
2520 ROBOdoc documented silclog header file.
2521 SilcLogCb now returns bool to wether inihibit the default
2522 handler or not (to keep the old behaviour return always TRUE).
2523 The new APIs should also fix the problem of the
2524 silcd_error.log file that was written in the current directory.
2527 Log files streams will remain opened after silc_log_set_file()
2528 call, means less CPU usage notably on high traffic servers.
2529 File streams are now full buffered, and flushed to the disk
2530 every 5 minutes, lesses HD activity and CPU usage.
2531 Messages can be redirected, allowing admins to configure
2532 one single logfile for all server messages.
2533 the silc_log_quick global variable to activate fast-logging.
2534 Affected files lib/silcutil/silclog.[ch]
2536 * Changed some code to conform new silclog APIs. Affected
2537 files are doc/example_silcd.conf.in, silcd/server.c
2538 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2541 * Fixed a memory leak that could occur in some situations.
2542 Affected file silcd/serverconfig.c.
2544 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2546 * Added the silc_client_del_client to remove the client from
2547 all channels as well. Affected file lib/silcclient/idlist.c.
2549 * Fixed the client library to correctly remove the client
2550 from all channels when the client entry is being destroyed.
2551 Affected file lib/silcclient/client_notify.c, command.c.
2553 * Added auto-nicking support to the client library. If the
2554 applicatio now sets client->nickname it will be sent to the
2555 server after connecting by the library. This way for example
2556 SILCNICK (or IRCNICK) environment variables will have effect
2557 and always change the nickname automatically to whatever
2558 it is wanted. Affected file lib/silcclient/client.[ch].
2560 * Renamed silc_server_command_bad_chars to the
2561 silc_server_name_bad_chars and moved it to the
2562 silcd/server_util.[ch]. Added also new function
2563 silc_server_name_modify_bad to return nickname that
2564 includes bad characters as new nickname without those
2565 bad characters. This check and modify is now used in
2566 silc_server_new_client when the username is initially set
2567 as nickname, so it must be checked to be valid nickname.
2568 Affected file silcd/packet_receive.c.
2570 * The nickname length is now taken from the packet for real
2571 and not trusted to strlen() since it clearly can return
2572 wrong length for nickname including bad characters. This
2573 also applies to channel names. Affected file silcd/command.c.
2575 * Removed the lib/silcsilm/modules directory. Modules are now
2576 compiled into the lib/silcsim. Fixed the copying of the
2577 modules to follow symbolic links in Makefile.am.pre.
2579 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2581 * Fixed silc_string_regexify list creation. Fixes bugs with
2582 BAN and INVITE commands in server. The affected file is
2583 lib/silcutil/unix/silcunixutil.c.
2585 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Removed the command destructor entirely from the server's
2588 command and command reply routines. It is not needed, and
2589 its usage was buggy and caused crashes. Affected files are
2590 silcd/command[_reply].[ch].
2592 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Cancel protocol and NULL sock->protocol if timeout
2595 occurred during protocol. Affected file silcd/server.c.
2597 * Cancel protocol timeouts always before calling the final
2598 callback, to assure that after final callback is called
2599 no other state will be called for the protocol anymore.
2600 Affected file silcd/protocol.c.
2602 * Print error log if incoming connection configuration could
2603 not be found. Affected file silcd/server.c.
2605 * Fixed JOIN command to correctly save the founder mode
2606 to the client on normal SILC server, when the channel
2607 was created by the router. Affected file silcd/command.c.
2609 * Fixed LIST command (hopefully) to send correct reply
2610 packets. Affected file silcd/command.c.
2612 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * The silc_packet_receive_process now returns FALSE if the
2615 read data was invalid packet, and TRUE if it was ok.
2617 The server now checks that if unauthenticated connection
2618 sends data and its processing fails the server will close
2619 the connection since it could be a malicious flooder.
2621 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2623 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2625 * Make sure the warning about error opening a log file is
2626 printed only once and not everytime it fails (produces
2627 too much useless log). Affected file lib/silcutil/silclog.c.
2629 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2631 * Made the silc_server_daemonise() function more readable.
2632 Affected file silcd/server.c.
2634 * Pid file is now optional, the user may comment it out from
2635 the config file. Removed define SILC_SERVER_PID_FILE, we
2636 don't need a default any longer. Affected file
2637 configure.in.pre, lib/Makefile.am.pre.
2639 * Make some use of the pid file. The server now dies at startup
2640 if it detects a valid pid file on his path. The server would
2641 die anyway in this circumstance, because of the bind() failure.
2642 Affected file silcd/silcd.c.
2644 * No longer compiling lib/dotconf.
2646 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Fixed JOIN command parsing not to crash. Affected file
2649 lib/silcclient/command.c.
2651 * Fied the NICK_CHANGE notify to add the new client entry
2652 even it is resolved. This removes an <[unknown]> nick
2653 thingy bug in the client. Affected file is
2654 lib/silcclient/client_notify.c.
2656 * Do not try to allocate 0 bytes (efence does not like it)
2657 in lib/silccore/silccomand.c when encoding payload.
2659 * Do not take IRCNICK as nickname in Irssi SILC client since
2660 it is not possible to set nickname before hand connecting
2661 the server (TODO has an entry about adding auto-nicking
2664 * Changed the silc_server_command_pending to check whether
2665 there already exists an pending entry with the specified
2666 command, command identifier and pending callback. This is
2667 to fix IDENTIFY and WHOIS related crashes that may register
2668 multiple pending commands with same identifier. Affected
2669 file silcd/command.c.
2671 * Fixed the server to reconnect to the router even if it
2672 was already reconnecting and EOF was received. This to
2673 fix a possibility that the server wouldn't ever try to
2674 auto-reconnect to the router. Affected file silcd/server.c.
2676 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed the server's password authentication to use the
2679 length of the locally saved password, and not the one
2680 sent in the packet. Affected file silcd/protocol.c.
2682 * Fixed same password authentication problem in the
2683 Authentication Payload handling routines in
2684 lib/silccore/silcauth.c.
2686 * Yet another password authentication problem fixed with
2687 channel password handling in silcd/command.c.
2689 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * If first character of string in silc_parse_userfqdn is '@'
2692 then do not parse it. Affected file is
2693 lib/silcutil/silcutil.c.
2695 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Fixed minor bug in IDENTIFY command reply sending, which
2698 caused various weird problems during JOIN when it was
2699 resolving names for users. Affected file silcd/command.c.
2701 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Fixed the IDENTIFY command reply sending to chech better valid
2704 clients. It was possible to send incomplete list of replies.
2705 Affected file silcd/command.c.
2707 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Added silc_client_command[s]_[un]register functions now to
2710 dynamically register the commands in client library. Removed
2711 the static table of commands. This allows the client library
2712 to call commands without causing the application to know about
2713 what commands library has called.
2715 Removed the INFO command reply kludge to detect when the command
2716 was called by library. Now library use its own command reply
2717 function for INFO command.
2719 Added function silc_client_command_call to call a command.
2720 Application can use it to call command, not access the structure
2723 Now all commands that are sent by the client library (not
2724 explicitly sent by application) use own command reply functions.
2726 Affected files around lib/silcclient/ and in
2727 irssi/src/silc/core/.
2729 * Fixed the WHOIS command reply sending to chech better valid
2730 clients. It was possible to send incomplete list of replies.
2732 Fixed the WHOIS and IDENTIFY to send the request to router
2733 if normal server did not do it and did not find any results.
2735 Affected file silcd/command.c.
2737 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * Moved the internal data from SilcClient context into its
2740 own file, not accesible to application. Affected files
2741 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2742 and other files in client library.
2744 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Added doc/examples installation target in Makefile.am.pre.
2749 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2752 commands the found client entry will be removed from the
2753 cache, after notifying application about the error. Affected
2754 file lib/silcclient/command_reply.c.
2756 * Changed the /MSG to check for exact nickname user gave, and
2757 not let `nick' match `nick@host' if it is only one found. Now,
2758 user must type the exact nickname (like nick@host2) even if
2759 there are no more than one same nicks found. This is to avoid
2760 a possibility of sending nickname to wrong nickname since
2761 `nick' could match `nick@host'. Affected file is
2762 irssi/src/core/silc-servers.c.
2764 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Do not print "you are now server operator" or similar when
2767 giving /away command. Affected files are
2768 irssi/src/silc/core/client_ops.c, silc-servers.h.
2770 * Made the silc_server_command_pending_error_check to send
2771 the same command reply payload it received back to the
2772 original sender of the command. This way all arguments
2773 that was received by the server will be received by the
2774 client too. Affected file silcd/command.c.
2776 * Added the silc_idcache_add to return the created cache entry
2777 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2779 * Add global clients to expire if they are not on any channel.
2780 This is because normal server will never know if they signoff
2781 if they are not on any channel. The cache expiry will take
2782 case of these entries. This is done by normal servers only.
2783 The affected files are silcd/command_reply.c,
2784 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2786 * If server receives invalid ID notification for WHOIS or
2787 IDENTIFY and the ID exists in the lists, it is removed.
2788 Affected file silcd/command_reply.c.
2790 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2791 in client then client entry that it matches is searched and
2792 the nickname is printed on the screen for user. Affected
2793 file irssi/src/silc/core/client_ops.c.
2795 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Use cache entry expire time in the LIST command reply to
2798 purge old entries from the cache after the LIST command
2799 reply has been received. This way we don't have non-existent
2800 entries in the cache for too long. Affected file is
2801 silcd/command_reply.c.
2803 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * If we are normal server, and we've not resolved client info
2806 in WHOIS or IDENTIFY from router, and it is global client,
2807 we'll check whether it is on some channel. If it is not
2808 then we cannot be sure about its validity and will resolve it
2809 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2810 file silcd/command.c.
2812 * Search channel by name (if possible) rather than by ID
2813 in IDENTIFY command's command reply. Affected file is
2814 silcd/command_reply.c.
2816 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2819 Updated specs and implemented it. Affected file silcd/command.c,
2820 silcd/packet_send.c and silcd/packet_receive.c.
2822 * Implemented the <founder auth> payload handling in the JOIN
2823 command. If provided all conditions for channel joining
2824 except requirement to provide correct passphrase can be
2825 overrided by the channel founder. Updated the protocol specs.
2826 Affected file silcd/command.c.
2828 Added support for founder auth in JOIN command in client
2829 library. Fixed the parsing of the JOIN command now to support
2830 all options as they should be. The affected file is
2831 lib/silcclient/command.c.
2833 * Optimized the WHOIS and IDENTIFY commands to send the request
2834 to router only if it includes nicknames or other names. If
2835 they include only IDs then check the local cache first before
2836 routing. Affected file is silcd/command.c.
2838 * Added channels topic announcements. Affected file is
2839 silcd/packet_receive.c and silcd/server.c.
2841 * Fixed the silc_server_send_notify_topic_set to really destine
2842 the packet to channel. Affected file silcd/packet_send.c.
2844 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2845 library. Affected file lib/silcclient/client_notify.c.
2847 * Added UMODE announcements. Affected file silcd/server.c.
2849 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Memory leak fixes in:
2853 lib/silcutil/silcsockconn.c
2854 lib/silcske/silcske.c
2855 lib/silcske/groups.c
2857 lib/silccrypt/silcpkcs.c
2858 lib/silccore/silccommand.c
2859 lib/silccore/silcidcache.c
2864 * ROBOdoc documented the lib/silcske/groups.h file and a
2865 bit changed the interface for better.
2867 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2869 * Update the client entry context in the ID cache after
2870 nick change. Affected file lib/silcclient/command.c.
2871 Fixes the CUMODE command when regaining founder privileges,
2872 and a little WHOIS problem.
2874 * Fixed silc_net_gethostbyname to correctly call the
2875 inet_ntop. Affected file lib/silcutil/silcnet.c.
2877 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2879 * Added IPv6 support checking to the configure.in.pre, added
2880 also --enable-ipv6 option to override the check. Affected
2881 file configure.in.pre.
2883 * The silc_thread_create now calls the start function
2884 directly if threads support is not compiled in. Removes
2885 ugly #ifdef's from generic code. Affected files are
2886 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2888 * Added silc_net_gethostby[name/addr]_async to asynchronously
2889 resolve. Affected files are lib/silcutil/silcnet.[ch].
2891 * Added support for rendering IPv6 based server, client and
2892 channel IDs. Affected file lib/silcutil/silcutil.c.
2894 * Added support for creating IPv6 based server IDs. Affected
2895 file is silcd/serverid.c.
2897 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2899 * Added silc_net_gethostby[addr/name] into the
2900 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2901 routines. Added silc_net_is_ip[4/6]. Affected file is
2902 lib/silcutil/unix/silcunixnet.c. All routines that take
2903 address as argument now supports both IPv4 and IPv6 addresses.
2905 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2907 * Fixed LIST command reply sending in server. Affected file
2910 * Server now sends the kicker's client ID in the KICK notify
2911 to the kicked client. Affected file silcd/command.c.
2913 * The client library now parses the kickers client ID and
2914 UI displays it. Affected files lib/silcclient/client_notify.c
2915 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2917 * Made all payload parsing function prototypes consistent.
2918 They all take now const unsigned char * and uint32 pair as
2919 the payload data instead of SilcBuffer. Changes all around
2920 the source tree. Other unsigned char* -> const unsigned char*
2921 changes around the tree as well.
2923 * Optimized SFTP client and server packet sending not to
2924 allocate new buffer for each packet but to recycle the
2925 first allocated buffer. Affected files are
2926 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2928 * Optimized the SFTP client to use SilcList instead of
2929 SilcDList for requests, because it is faster. Affected file
2930 is lib/silcsftp/sftp_client.c.
2932 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2933 into lib/silccore/silcid.[ch].
2935 Renamed silcpayload.[ch] into silcargument.[ch].
2937 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * If client entry is deleted with active key agreement
2940 session, abort the session.
2942 The silc_client_abort_key_agreement now calls the completion
2943 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2945 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2948 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Don't use __restrict in older GCC's. Affected file is
2951 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2953 * silc_net_localhost now attempts to reverse lookup the
2954 IP/hostname. Affected file lib/silcutil/silcnet.c.
2956 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2957 command. It can be used to gain founder privileges at
2958 the same time when joining the channel.
2960 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2961 kicker's client ID as well. Updated protocol specs.
2963 Defined that the server must send SILC_COMMAND_IDENTIFY
2964 command reply with error status to client who sent
2965 private message with invalid client ID.
2967 Updated the protocol specification.
2969 * Added silc_server_send_command_reply to send any
2970 command reply. Affected file silcd/packet_send.[ch].
2972 * Added silc_id_payload_encode_data to encode ID payload
2973 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2975 * The server now send IDENTIFY command reply with error
2976 status if client ID in private message is invalid. Affected
2977 file silcd/packet_receive.c.
2979 * Save the server key file with server's IP address in
2980 the filename instead of hostname. The affected file is
2981 irssi/src/silc/core/client_ops.c.
2983 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2988 * Added libtool support for compiling shared objects in
2989 lib/silcsim. Affected file configure.in.pre and
2990 lib/silcsim/Makefile.am. Original patch by cras.
2992 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Pid file configuration, and server's config file fixes
2995 patch by toma. Updated CREDITS file.
2997 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Fixed silc_client_channel_message to not try to decrypt
3000 the message twice if it resolved the destination client
3001 information. This could cause of dropping one channel
3002 message. Affected file lib/silcclient/client_channel.c.
3004 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3007 lib/silcclient/client.c. This function is used when the SILC
3008 Client is run under some other scheduler, or event loop or
3009 main loop. On GUI applications, for example this may be
3010 desired to used to run the client under the GUI application's
3011 main loop. Typically the GUI application would register an
3012 idle task that calls this function multiple times in a second
3013 to quickly process the SILC specific data.
3015 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3017 * Fixed silc_server_drop() for dropping the supplementary
3018 groups as well, this could cause a security hole on some
3021 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

3027 to run server on foreground. A patch by debolaz.
3028 Affected files silcd/server.c, silcd/silcd.c.
3030 * Fixed MOTD to return the MOTD file server name. Affected
3031 file silcd/command.c.
3033 * Added INFO command reply handling to the Irssi SILC Client.
3034 Affected file irssi/src/silc/core/client_ops.c.
3036 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Fixed the silc_idcache_list_* routines to really support
3039 the dynamic list. Fixes a crash. Affected file is
3040 lib/silccore/silcidcache.c.
3042 * Fixed the LIST command reply to really call LIST command's
3043 pending callbacks. Affected file silcd/command_reply.c.
3045 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Update conn->local_entry->nickname after giving NICK
3048 command. Affected file lib/silcclient/command.c.

3052 * Added the [pid] option to the silcd configuration file
3054 Affected files: serverconfig.[ch] and silcd.c
3056 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Save fingerprint in WHOIS command reply in server.
3059 Affected file silcd/command_reply.c.
3061 * Fixed NICK commands pending callback registration.
3062 Affected file lib/silcclient/command.c.
3064 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Use ++server->cmd_ident when sending commands in server,
3067 instead of random number. Affected file silcd/command.c.
3069 * Fixed GETKEY command reply to call actually GETKEY pending
3070 command callbacks. Affected file silcd/command_reply.c.
3072 * A bit stricter check for nicknames. Check for same nickname
3073 in NICK command also. Affected file silcd/command.c.
3075 * Do not call INFO command everytime client ID changes, only
3076 during first connecting. Affected file lib/silcclient/client.c.
3078 * Set the new nickname only after successful command reply for
3079 NICK command is returned by server. Affected file
3080 lib/silcclient/command.c.
3082 * Remove nicknames from nicklist during server_signoff notify.
3083 Should fix /NAMES bit more. The affected file is
3084 irssi/src/silc/core/silc-channels.c.
3086 * Added `fingerprint' field to the SilcIDListData in the
3087 silcd/idlist.h to hold the fingerprint of the client's
3090 Send the fingerprint of the client's public key in WHOIS
3093 Affected files silcd/command.c, and silcd/idlist.[ch].
3095 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3096 create fingerprint from given data.
3098 * Show the fingerprint of the client's public key in WHOIS.
3099 Affected files irssi/src/module-formats.[ch] and
3100 irssi/src/silc/core/client_ops.c.
3102 * Format the multiple same nicknames also during JOIN and
3103 NICK_CHANGE notifys. Affected file is
3104 lib/silcclient/client_notify.c.
3106 * Do not print error on screen for invalid private message
3107 payload since it can come if someone is sending private
3108 messages with wrong key. Affected file
3109 lib/silccore/silcprivate.c.
3111 * Fixed multiple concurrent /PING crash. Affected file
3112 lib/silcclient/command.c.
3114 * Changed the wrong ID encoding. All IP addresses must be
3115 in MSB first order in encoded format. They were encoded
3116 wrong and was in LSB format. Affected files are
3117 silcd/serverid.c, lib/silcutil/silcutil.c.
3119 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3121 * Call the `connect' client operation through the scheduler
3122 in case of error. Affected file lib/silcclient/client.c.
3124 * Call the `failure' client operation even if the error
3125 occurred locally during a protocol. Affected file is
3126 lib/silcclient/protocol.c.
3128 * Added support of sending LIST command to router from normal
3129 server. This way normal server can get list of all channels
3130 in the network too. Fixed the channel list sending in the
3131 server too. Affected files are silcd/command.c, and
3132 silcd/command_reply.[ch].
3134 * Added silc_server_update_channels_by_server and
3135 silc_server_remove_channels_by_server. They are used during
3136 disconnection of primary router and in backup router protocol.
3137 Affected file silcd/server_util.[ch], silcd/server.c and
3138 silcd/server_backup.c.
3140 * Fixed channel adding to global list in IDENTIFY command
3141 reply in server. Affected file silcd/command_reply.c.
3143 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * If the incoming packet type is REKEY or REKEY_DONE process
3146 that packet always synchronously. Fixes yet another MAC
3147 failed error on slow (dialup) connections. Affected file
3148 lib/silcclient/client.c and silcd/server.c.
3150 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3152 * Call check_version SKE callback for initiator too. Affected
3153 file lib/silcske/silcske.c.
3155 * Implemented fix for security hole found in the SKE that was
3156 fixed in the specification few days back; the initiator's
3157 public key is now added to the HASH value computation.
3158 Added backwards support for the old way of doing it too, for
3159 old clients and old servers. Affected file is
3160 lib/silcske/silcske.c.
3162 * Enabled mutual authentication by default in SKE. If initiator
3163 is not providing mutual authentication the responder will
3164 force it. This will provide the proof of posession of the
3165 private key for responder. The affected files are
3166 lib/silcclient/protocol.c and silcd/protocol.c.
3168 * Do not cache anymore the server's public key during SKE.
3169 We do mutual authentication so the proof of posession of
3170 private key is done, and if the server is authenticated in
3171 conn auth protocol with public key we must have the public
3172 key already. Affected file silcd/protocol.c.
3174 * Added new global debug variable: silc_debug_hexdump. If
3175 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3176 file lib/silcutil/silclog.[ch].
3178 * Fixed compilation warning due to char * -> const char *.
3179 Affected files lib/silcutil/silcnet.h, and
3180 lib/silccore/silcauth.[ch].
3182 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Fixed CMODE command when new channel key was created. If
3185 the creation failed the old key was removed. Next time giving
3186 same command would crash the server since the old key was
3187 freed already. Affected file silcd/command.c.
3189 * Fixed the silc_server_announce_get_channels to not crash
3190 on reconnect. Affected file silcd/server.c.
3192 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Added silc_log_set_debug_string function to set a regex
3195 string to match for debug output. Only the function names,
3196 or filenames matching the given debug string is actually
3197 printed. This way it is possible to filter out those debug
3198 strings that user is not interested in.
3200 Fixed a bug in silc_string_regexify.
3202 Affected files lib/silcutil/silclog.[ch], and
3203 lib/silcutil/unix/silcunixutil.c.
3205 * Changed the -d options in both server and Irssi SILC client
3206 to take the debug string as argument. Affected files
3207 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3209 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * Added silc_hash_babbleprint to create a Bubble Babble
3212 Encoded fingerprint. The encoding is developed by Antti
3213 Huima (draft-huima-babble-01.txt), and it creates human
3214 readable strings out of binary data. Affected file
3215 lib/silccrypt/silchash.[ch].
3217 * Print the babble print now in addition of fingerprint as well
3218 in Irssi SILC client. Affected files are
3219 irssi/src/fe-common/silc/module-formats.[ch],
3220 irssi/src/fe-common/silc/core/client_ops.c.
3222 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3224 * Fixed a security problem found in SKE. The initiator's
3225 public key too is now added to the HASH hash value creation
3226 which is signed by the responder to create the SIGN value.
3227 This will prevent anyone in the middle to lie to the responder
3228 about the initiator's public key. If this is done now, the
3229 man in the middle will get caught. Updated the protocol
3232 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Better installation directory handling. Configure module
3235 paths and other paths automatically to example_silc* files
3236 in doc/. A patch by toma.
3238 * Fixed compiler warning from MPI library, and from SILC RNG.
3241 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3242 It can be configured with ./configure. A patch by toma.
3244 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3246 * Find correct make to use in prepare-clean. A patch by
3247 toma. Affected file prepare-clean.
3249 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3251 * Added irssi variables use_auto_addr, auto_bind_ip,
3252 auto_bind_port and auto_public_ip.
3254 * Changed the interface for silc_client_send_key_agreement
3255 in lib/silcclient/silcapi.h
3259 irssi/src/silc/core/silc-core.c
3261 lib/silcclient/silcapi.h
3262 irssi/src/silc/core/silc-channels.c
3263 lib/silcclient/client_keyagr.c
3266 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Added silc_pkcs_public_key_compare to compare two
3269 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3271 * Check that the client who set the founder mode on the
3272 channel is the same client that is giving the founder
3273 mode to itself. It is done by comparing the saved public
3274 key (it is saved even in the authentication is passphrase).
3275 Affected file silcd/command.c.
3277 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Do not process packet for disconnected socket connection.
3280 Affected file lib/silccore/silcpacket.c.
3282 * Process the DISCONNECT packet through scheduler in the
3283 client library. Affected file lib/silcclient/client.c.
3285 * Fixed the silc_client_packet_parse to not to increase
3286 the packet sequence number if the conn->sock and the
3287 current socket connection is not same. This can happen
3288 for example during key agreement when the conn includes
3289 multiple socket connections (listeners). Affected file
3290 lib/silcclient/client.c.
3292 * The sender of the file transfer request now provides also
3293 the pointer (listener) for the key exchange protocol. If
3294 the listener cannot be created then it sends empty key
3295 agreement and lets the receiver provide the listener.
3297 Added `local_ip' and `local_port' arguments to the
3298 silc_client_file_send. If they are provided they are used,
3299 if not then it will attempt to find local IP address, if
3300 not found or bind fails then the remote client will provide
3303 Affected files are lib/silcclient/client_ftp.c and
3304 lib/silcclient/silcapi.h.
3306 * Extended the FILE SEND command to support defining the
3307 local IP and port for key exchange listener. They are
3308 optional. Affected file irssi/src/silc/core/silc-servers.c.
3310 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Defined to WHOIS command reply the sending of fingerprint
3313 of the client's public key (if the proof of posession of the
3314 corresponding private key is verified by the server).
3315 Updated to the protocol specification.
3317 * Added support of receiving the client's public key's
3318 fingerprint in command reply in client library. Affected
3319 file is lib/silcclient/command_reply.c, and
3320 lib/silcclient/idlist.[ch].
3322 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3324 * Do not send over 128 chars long nickname to the server
3325 in NICK command. Affected file lib/silcclient/command.c.
3327 * Do not send over 256 chars long channel names to the server
3328 in JOIN command. Affected file lib/silcclient/command.c.
3330 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3332 * Assure that silc_server_close_connection cannot be called
3333 twice for same socket context. Affected file is
3336 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Send error message to application if opening file for
3339 writing during file transfer fails. Affected file is
3340 lib/silcclient/client_ftp.c.
3342 Remove all file transfer sessions for a client that we're
3343 removing from ID cache.
3345 Affected file is lib/silcclient/client_ftp.c.
3347 * Fixed silc_net_addr2bin to return correct address. Affected
3348 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3350 * Fixed file transfer session removing on signoff notify.
3351 Affected file irssi/src/silc/core/silc-servers.c.
3353 * Added the SilcClientFileError to be returned in the monitor
3354 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3355 Affected file lib/silcclient/silcapi.h.
3357 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Fixed a crash in silc_client_ftp_free_sessions and
3360 silc_client_ftp_session_free_client. Affected file
3361 lib/silcclient/client_ftp.c.
3363 * Added `disabled' field in the SilcChannelEntry in the server
3364 to indicate if the server entry is disabled. Affected file
3365 silcd/idlist.h, silcd/command[_reply].c.
3367 * SILC server adds now /var/run/silcd.pid everytime it is
3368 started. Affected file silcd/silcd.c.
3370 * Added silc_server_packet_send_clients to send a packet to
3371 the provided table of client entries. Affected file
3372 silcd/packet_send.[ch].
3374 * Fixed a crash in client resolving in client_prvmsg.c in
3375 client library. Affected file lib/silcclient/client_prvmsg.c.
3377 * Do not actually remove the client directly from ID cache
3378 during SERVER_SIGNOFF, but invalidate it. This way we
3379 preserve the WHOWAS info for the client. Affected file
3380 silcd/server_util.c.
3382 * Fixed SERVER_SIGNOFF notify handling in the server. The
3383 server is now able to process incoming SERVER_SIGNOFF notify
3384 for a server that it doesn't even know about. It will remove
3385 the clients provided in the notify. Affected file
3386 silcd/packet_receive.c.
3388 * Check for partial packet in data queue after every packet that
3389 was found from the queue. Return and wait for more data if
3390 there is partial data in queue. Affected file is
3391 lib/silccore/silcpacket.c.
3393 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Added SilcClietFileError enum to indicate error in
3396 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3397 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3398 Affected files lib/silcclient/silcapi.h and
3399 lib/silcclient/client_ftp.c.
3401 * Check that newsize in silc_buffer_realloc is larger than
3402 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3404 * Added better monitor of file transfers. It now monitors
3405 key agreement protocol during the file transfer too. Added
3406 error reporting too. Affected files
3407 irssi/src/silc/core/silc-servers.c,
3408 irssi/src/fe-common/silc/module-formats.[ch].
3410 * Wrote a help file for FILE command.
3412 * Added silc_rng_global_get_byte_fast to get not-so-secure
3413 random data as fast as possible. Random data is read from
3414 /dev/urandom if available and from the SILC RNG if not
3415 available. It is used in padding generation. Affected file
3416 lib/silccrypt/silcrng.[ch].
3418 * All packets in client library are now processed synchronously.
3419 Optimized packet processing a lot. Affected file
3420 lib/silcclient/client.c.
3422 * All server connection packets are processing synchronously
3423 now in server, to optimize packet processing. Affected file
3426 * Include files are installed now only in Toolkit distribution
3427 if make install is given. Affected files: all Makefile.am's.
3429 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Assure that silc_client_notify_by_server_resolve does not
3432 resolve the client information multiple times. If it cannot
3433 be found by the first it cannot be found at all. Affected
3434 file lib/silcclient/client_notify.c.
3436 * Fixed WHOWAS command reply calling. Affected file
3437 lib/silcclient/command_reply.c.
3439 * Removed all references to silc_idlist_get_client from the
3440 Irssi SILC client since that call is internal call used by
3441 the library. The Irssi SILC client will use now client
3442 retrieval functions found in silcapi.h.
3444 * Fixed a bug in resolving nickname info before sending
3445 private message. It used freed memory. Affected file
3446 irssi/src/silc/core/silc-servers.c.
3448 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Assure my_channels statistics cannot go negative in server.
3451 Affected files silcd/server.c, silcd/server_util.c.
3453 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3457 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Win32 Toolkit changes. Affected files
3460 win32/silc.dsw, win32/libsilc/libsilc.def,
3461 win32/libsilcclient/libsilc.def,
3462 lib/silcutil/silcutil.c, and
3463 lib/sftp/sftp_fs_memory.c.
3465 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Added silc_net_localip to return local host's IP address.
3468 Affected file lib/silcutil/silcnet.[ch].
3470 * If key exchange or rekey protocol is active for a connection
3471 parse all packets syncronously since there might be packets
3472 in packet queue that we are not able to process without first
3473 processing packets before them. Affected file silcd/server,
3474 lib/silcclient/client.c.
3476 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3477 whether library should continue processing the packet.
3478 Affected file lib/silccore/silcpacket.h.
3480 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3481 SilcSFTPMonitorData to SFTP server to monitor various
3482 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
3483 lib/silcsftp/sftp_server.c.
3485 * Added silc_file_size to return file size. Affected file
3486 lib/silcutil/silcutil.[ch].
3488 * Implemented the file transfer support for the client library.
3489 Added preliminary support for simple client to client one-file
3490 transmission. Affected file lib/silcclient/client_ftp.c,
3491 lib/silccilent/client.[ch].
3493 * Added new local command FILE to the Irssi SILC Client.
3494 It is used to perform the file transfer. It has subcommands
3495 SEND, RECEIVE, SHOW and CLOSE. Affected files
3496 irssi/src/silc/core/client_ops.c,
3497 irssi/src/silc/core/silc-server.[ch].
3499 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Relay the SILC_PACKET_FTP in the server. Affected files
3502 silcd/server.c and silcd/packet_receive.c.
3504 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3506 * Renamed silc_file_read and silc_file_write to functions
3507 silc_file_readfile and silc_file_writefile. Added function
3508 silc_file_open and silc_file_close. Affected files
3509 lib/silcutil/silcutil.[ch].
3511 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3513 * Resolve the client info when received private message or
3514 channel message for a client which nickname we don't know.
3515 Affected files lib/silcclient/client_prvmsg.c and
3516 lib/silcclient/client_channel.c.
3518 * Do not crash in /KEY if client is not connected. Affected
3519 file irssi/src/silc/core/silc-channels.c.
3521 * Added SilcClientStatus field to the SilcClientEntry in the
3522 lib/silcclient/idlist.h.
3524 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3525 is incomplete and is being resolved, it won't be resolved
3528 Make sure also that USERS command reply does not resolve
3529 twice information. Affected file is
3530 lib/silcclient/command_reply.c.
3532 Make sure that silc_client_get_clients_by_list does not
3533 resolve twice same information.
3535 * Check for valid client->id in the silc_server_free_client_data.
3536 Affected file silcd/server.c.
3538 * Fixed /GETKEY nick@server not to crash if the server entry
3539 is not found. Affected file lib/silcclient/command.c.
3541 * Fixed the silc_server_check_cmode_rights to check the
3542 requested modes correctly. Affected file silcd/command.c.
3544 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Better checks for non-printable chars in nick added.
3547 Affected file silcd/command.c.
3549 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Call the silc_server_udpate_servers_by_server in the
3552 primary router that comes back online in the backup resuming
3553 protocol. Otherwise it routes packets wrong. Affected file
3554 silcd/server_util.[ch], silcd/server_backup.c.
3556 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3559 lib/silcutil/silcbuffmt.[ch].
3561 * Redefined the SILC packet header to include the padding
3562 length. Affected file lib/silccore/silcpacket.[ch].
3564 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3565 length for maximum padding up to 128 bytes). Affected
3566 file lib/silccore/silcpacket.h.
3568 * Removed all backwards support for old 0.5.x MAC thingies.
3569 The SILC packet header change makes it impossible to be
3570 backwards compatible.
3572 * Send the ENDING packet with timeout in the backup resuming
3573 protocol. This is to assure that all routers has connected
3574 to the primary router. Affected file silcd/server_backup.c.
3576 * Changed the RNG to take the first IV from random data. It
3577 used to take it from zero actually. Changed the RNG also
3578 to use /dev/urandom during session. /dev/random is used
3579 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3581 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3583 * Changed the SILC packet header to have the first two bytes
3584 (the packet length) encrypted. Affected files aroung the
3585 code tree, lib/silccore/silcpacket.[ch]. Removed the
3586 SilcPacketCheckDecrypt callback. It is not needed anymore
3587 since the silc_packet_receive_process will determine now
3588 whether the packet is normal or special.
3590 * Implemented the unidirectional MAC keys. Affected files
3591 lib/silcske/silcske.c, silcd/protocol.c and
3592 lib/silcclient/protocol.c.
3594 * Implemented the packet sequence number to the MAC computation.
3595 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3596 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3597 lib/silcclient/protocol.c.
3599 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Allow backup router to announce servers. All servers
3602 announced by backup router are added to the global list
3603 automatically. Update hte server's socket to our primary
3604 router also when backup router announces a server.
3605 Affected file silcd/packet_receive.c.
3607 * Do not update the client->router in the function
3608 silc_server_udpate_clients_by_server if the client is on
3609 global list. We might fail to find any specific server
3610 for locally connected clients and local cell clients. They
3611 should still use the `from' and not `to' as client->router.
3612 This fixes backup router resuming protocol. Affected file
3613 silcd/server_util.c.
3615 * Decrease channel statistics count only if the channel
3616 deletion worked. Affected files are silcd/server.c and
3617 silcd/server_util.c.
3619 * Added silc_server_update_servers_by_server to update origin
3620 of all server entries. Used during backup router protocol.
3621 Affected files silcd/server_util.[ch], silcd/server.c. and
3622 silcd/backup_router.c.
3624 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3625 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3626 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3627 lib/silccrypt/silchmac.c.
3629 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Assure that router cannot reroute the same channel message
3632 to the sender. Affected file silcd/packet_receive.c.
3634 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Made better checks that the channel message is not sent
3637 to the router it came from. Affected file is
3638 silcd/packet_send.c. Fixed memory leak too.
3640 * Announce informations for incoming router connection, but
3641 only after checking if it is replaced by backup router.
3642 Affected file silcd/packet_receive.c.
3644 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Fixed the backup resuming protocol to work in multiple
3647 router environment. Affected file silcd/server_backup.c.
3649 * Route packet only to one router in the function
3650 silc_server_packet_send_to_channel. Affected file is
3651 silcd/packet_send.c.
3653 * Fixed silc_server_send_notify_dest to set the broadcast
3654 flag. Fixed the silc_server_send_notify_topic to actually
3655 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3656 Affected file silcd/packet_send.c.
3658 * Changed the SFTP Filesystem interface. Changed the
3659 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3660 the filesystem operation function. The SilcSFTPFilesystem
3661 is now a context that is allocated by all filesystem allocation
3662 functions and it already includes the operations structure
3663 and filesystem specific context. It is given as argument
3664 now to the silc_sftp_server_start. This made the interface
3665 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3666 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3668 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3670 * Changed the backup router adding and getting interfaces
3671 in the server. The router that will be replaced by the
3672 specified backup router is now sent as argument. Affected
3673 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3676 * Added silc_net_addr2bin_ne to return the binary form of
3677 the IP address in network byte order. Affected files
3678 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3680 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3682 * Check for existing server ID in silc_server_new_server
3683 and in silc_server_connect_to_router_final and remove the
3684 old entry if it exists. Affected file silcd/packet_receive.c,
3687 * Send the channel message always to only one router, either
3688 in upstream or downstream. Affected file is
3689 silcd/packet_send.c.
3691 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Wrote the definition of the backup resuming protocol to the
3694 protocol specification.
3696 * Removed one redundant channel key generation from normal
3697 server during joining procedure. Removed one redundant
3698 channel key sending from server to router during joining
3699 procedure. Affected file silcd/command.c.
3701 * Made minor bugfixes to the backup router resuming protocol.
3702 Affected file silcd/server_backup.c, server.c.
3704 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Added --disable-asm configuration option. Affected files
3707 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3710 * Implemented the backup resuming protocol that is used to
3711 resume the primary router position in the cell after the
3712 primary router comes back online. Affected files
3713 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3714 and silcd/server_util.[ch].
3716 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3718 * Sleep two (2) seconds after sending QUIT command to server.
3719 Affected file lib/silcclient/command.c.
3721 * Assure that if outgoing data buffer is pending do not force
3722 send any data. Affected file silcd/packet_send.c.
3724 * Assure that if outgoing data buffer is pending do not force
3725 send any data. Affected file lib/silcclient/client.c.
3727 * Implemented the backup router support when the primary router
3728 goes down. The servers and routers can now use the backup
3729 router as new primary router without loosing connectivity.
3731 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3734 in the server to indicate disabled entry. All data read
3735 from the connection will be ignored and no data is sent
3736 for entry that is disabled. Affected files are
3737 silcd/idlist.h, silcd/server.c.
3739 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Created SFTP client and server test programs in the
3742 lib/silcsftp/tests directory.
3744 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Implemented memory filesystem (virtual filesystem) for
3747 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3750 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Implemented the SFTP (SSH File Transfer Protocol) to the
3753 lib/silcsftp. It includes SFTP client and SFTP server
3756 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Moved lib/silccore/silcprotocol.[ch] to the
3759 lib/silcutil library.
3761 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3762 take variable argument list pointer as argument. Affected
3763 file lib/silcutil/silcbuffmt.[ch].
3765 * Added silc_buffer_set function that is used to set data
3766 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3767 Affected file lib/silcutil/silcbuffer.h.
3769 * Changed various routines in the core library to use the new
3770 silc_buffer_set instead of allocating new buffer only for
3773 * Added 64-bit value formatting and unformatting support to the
3774 silc_buffer_[un]format routines. Affected file is
3775 lib/silcutil/silcbuffmt.[ch].
3777 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3778 to includes/bitmove.h.
3780 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Fixed channel user mode saving in client library. Affected
3783 file lib/silcclient/command[_reply].c.
3785 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Defined the file transfer to the SILC Protocol. Added
3788 new packet type SILC_PACKET_FTP and defined File Transfer
3789 Payload. The mandatory file transfer protocol is SFTP
3790 (SSH File Transfer Protocol). Affected file in addition
3791 of the internet draft is lib/silccore/silcpacket.h.
3793 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3794 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3795 is used as part of backup router protocol when the primary
3796 router of the cell is back online and wishes to resume
3797 the position as primary router.
3799 * Redefined the MAC generation keys in the protocol. The
3800 same key is not used anymore in both direction. Both
3801 direction will now use different keys for sending and
3802 receiving. This fixes a potential security flaw. This
3803 change causes incompatibilities in the protocol.
3805 * Redefined also the MAC computation from the packet.
3806 An packet sequence number is now added to the MAC
3807 computation. This prevents possible replay attacks against
3808 the protocol. This change too causes incompatibilities
3811 Added `sequence' field to the SilcPacketContext to hold
3812 the current sequence number for the packet.
3814 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * Added `created' field to the SilcIDListData in the file
3817 silcd/idlist.h to indicate the time when the entry was
3820 * Added `created' field to the SilcChannelEntry too. Affected
3821 file silcd/idlist.h.
3823 * Added `creation_time' aguments to all the announcement functions
3824 in the server. If it is provided then only the entries that
3825 was created after the provided time frame are actually
3826 announced. Affected file silcd/server.[ch].
3828 * The protocol says that the Channel ID's IP address must be
3829 based on the router's IP address. Added check for this in
3830 the silc_server_new_channel when processing incoming New Channel
3831 Payload. Affected file silcd/packet_receive.c.
3833 * Print out the correct version with --version in SILC client.
3834 Affected file irssi/src/silc/core/silc-core.c.
3836 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Fixed WHOWAS command to check for completnes of the client
3839 entry always, not just when the command is coming from client.
3840 Affected file silcd/command.c.
3842 * Added new function silc_server_packet_queue_purge to purge the
3843 outgoing data queue to the network. After the function returns
3844 it is guaranteed that the outgoing packet queue is empty.
3845 Affected file silcd/packet_send.[ch].
3847 * Purge the outgoing packet queue in the rekey protocol's final
3848 callback to assure that all rekey packets go to the network
3849 before quitting the protocol. Affected file silcd/server.c.
3851 * Added silc_client_packet_queue_parse as similar function as
3852 in server to the client library. The affected file is
3853 lib/silcclient/client.c.
3855 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Splitted silcd/server.c and created silcd/server_util.[ch]
3858 for utility functions.
3860 * Added new socket flag SILC_SF_DISABLED to indicate that the
3861 connection is open but nothing can be sent to or received from
3862 the connection. Affected file lib/silcutil/silsockconn.[ch].
3863 The checking for disabled socket is checked in the low level
3864 silc_socket_write and silc_socket_read functions.
3866 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Allow only nicknames and channel names that fits into the
3869 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3871 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * When processing JOIN command reply in server check that if
3874 the channel exists in our global list we'll move it the local
3875 list. Affected file silcd/command_reply.c.
3877 * Fixed the check whether client is joined on the channel already
3878 in JOIN command. Affected file lib/silcclient/command.c.
3880 * Fixed the JOIN command reply to check whether the channel
3881 already exists. Affected file lib/silcclient/command_reply.c.
3883 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Added silc_ske_status_string to map the SKE error numbers
3886 to readable strings. The affected files are
3887 lib/silcske/silcske[_status].[ch].
3889 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Do not show the private channels on the WHOIS channel list
3892 as it is not allowed by the protocol. The affected file is
3895 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3897 * Assure that the packet length digged from the actual packet
3898 is something sensible in the silc_packet_decrypt_rest_special
3899 in lib/silccrypt/silcpacket.c.
3901 * Free and NULL the allocated pointer in silc_hmac_alloc if
3902 the HMAC allocation fails. The affected file is
3903 lib/silccrypt/silchmac.c.
3905 * Print the selected security properties to the log files in
3906 the server. Affected file silcd/protocol.c.
3908 * Add SKE's reference counter even if calling the completion
3909 callback manually. Otherwise it goes negative, although it
3910 does not cause any problems. The affected file is
3911 lib/silcske/silcske.c.
3913 * Remove the client entry with short timeout after giving the
3914 KILL command. Affected file lib/silcclient/command.c.
3916 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3917 case all found clients are already disconnected (WHOWAS would
3918 found them) in the server. Affected file silcd/command.c.
3920 * Update the last_receive (time of last data received) to be
3921 updated only when received private or channel message so that
3922 the idle time showed in WHOIS makes more sense.
3924 * Added boolean field `valid' in to the SilcClientEntry in the
3925 client library to indicate whether the entry is valid or not.
3926 This fixes the nickname change bug on channel when changing
3927 the nickname to be same than the old (like nick to Nick) the
3928 nickname formatter doesn't set the new nick anymore to Nick@host.
3929 Affected file lib/silcclient/idlist.[ch].
3931 * Now actually fixed the nickname changing on disconnection.
3932 Added new function silc_change_nick to the Irssi SILC Client.
3933 Affected file irssi/src/silc/core/client_ops.c,
3934 irssi/src/silc/core/silc-nicklist.[ch].
3936 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * Check that the public key exists in the GETKEY command before
3939 trying to encode it. Affected file silcd/command.c.
3941 * Print some notifications on received public keys with GETKEY
3942 command in the Irssi SILC Client. Affected files are
3943 irssi/src/fe-common/silc/module-formats.[ch],
3944 irssi/src/silc/core/client_ops.c.
3946 * Use IDENTIFY command to resolve the server information in the
3947 GETKEY command instead of INFO command. Affected file
3948 lib/silcclient/command.c.
3950 * All command reply functions in the client library now calls
3951 the pending command reply callbacks even if an error has
3952 occurred. The server has done this a long time and now it was
3953 time to move the client library to this as well. Now all
3954 errors can be delivered back to the pending command reply
3955 callbacks if necessary. Affected files are
3956 lib/silcclient/command[_reply].[ch].
3958 * Change the nickname on disconnection back to the username
3959 because in reconnect the server will enforce it to it anyway.
3960 Affected file irssi/src/silc/core/silc-servers.c.
3962 * Fixed a config file parsing bug in the Irssi SILC client.
3963 Affected file irssi/src/silc/core/clientconfig.c.
3965 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3967 * When printing the channel mode on JOIN, verify that the
3968 channel key and channel's HMAC are valid. Affected file
3969 irssi/src/silc/core/client_ops.c.
3971 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3974 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3975 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3977 * Removed channel key rekey task deleting from the function
3978 silc_server_save_channel_key. Affected file silcd/server.c.
3979 Added explicit timeout task context instead that is used to
3980 delete the task if we are registering a new task before the
3981 new task has elapsed.
3983 * When channel key rekey occurs the client library now saves
3984 the old channel key for a short period of time (10 seconds) and
3985 is able to use it in case some is still sending channel
3986 messages encrypted with the old key after the rekey. Affected
3987 file lib/silcclient/[idlist.h|client_channel.c].
3989 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Added check to the silc_server_new_id_real to not accept
3992 new ID if it is the sender's own ID. Affected file is
3993 silcd/packet_receive.c.
3995 * Assure that we do not announce ourself or the one we've
3996 sending our announcements when we're router and are announcing
3997 servers to our primary router. Affected file silcd/server.c.
3999 * Fixed silc_server_command_identify_check_client to assemble
4000 correct WHOIS packet. It send corrupted WHOIS packet and
4001 caused problem with router to router connections. Affected
4002 file silcd/command.c.
4004 Fixed also silc_server_command_whois_check the same way
4005 as for the IDENTIFY command.
4007 * Added new SilcIDListStatus to the server in the SilcIDListData
4008 structure. The status now includes the current status of
4009 the entry (like registered, resolved etc.). Affected file
4010 silcd/idlist.[ch]. Defined a bunch of different status types
4011 as well. This replaced the old boolean registered field as well.
4013 Added resolve_cmd_ident field to the SilcClientEntry structure
4014 too so that if the entry is for example being resolved so
4015 another command may attach to the same pending command reply
4016 without requiring to resolve the same entry again. This concept
4017 should optimize the WHOIS and the IDENTIFY resolving under
4018 heavy load by taking away unnecessary resolving for entries
4019 that are being resolved already.
4021 Added support for adding multiple pending commands for one
4022 command idenfier. Affected file silcd/command[_reply].[ch].
4024 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4025 before deleting the data. Otherwise the hash table will have
4026 freed data in comparison functions. Affected file is
4027 silcd/command_reply.c.
4029 * Fixed silc_idlist_replace_client_id to add the new entry to
4030 the cache with NULL nickname. Otherwise there will be invalid
4031 memory as the nickname after the nickname is freed. Affected
4032 file silcd/packet_receive.c.
4034 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4035 saved into wrong slots because the previous number of entries
4036 was not taken into account. Affected file silcd/idlist.c.
4037 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4039 * If we are router and we receive JOIN notify to a channel that
4040 does not have any users then notified client is marked as the
4041 channel founder, as it is it. The affected file is
4042 silcd/packet_receive.c
4044 * Added to the extended hash table API's table_del_*ext functions
4045 the destructor as argument too, so that the caller can decide
4046 which destructor to use or whether to use destructor at all.
4047 Affected file lib/silcutil/silchashtable.[ch].
4049 * Fixed ID Cache purging. It actually deleted the entries from
4050 the hash table after the data was freed. The hash table ended
4051 up comparing freed memory. The affected file is
4052 lib/silccore/silcidcache.c.
4054 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4056 * Fixed Irssi SILC client's KILL command's HELP syntax.
4058 * The USERS command now resolves the detailed user information
4059 if the userinfo field is missing. Affected file is
4060 lib/silcclient/command_reply.c.
4062 * Do not print error in silc_file_read if the read file does
4063 not exist. Just silently return NULL. Affected file is
4064 lib/silcutil/silcutil.c.
4066 * Fixed the silc_log_output to not wine about NULL filename
4067 and to not create some bogus " " filename. Affected file is
4068 lib/silcutil/silclog.c.
4070 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Fixed various printing bugs on the user interface in the
4073 Irssi SILC Client. Minor changes that were forgotten from
4076 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Fixed the configure.in.pre and the compilation and distribution
4079 environment to support the new autoconf 2.52. That version is
4080 now required to compile the CVS trunk.
4082 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4085 to generally parse user@fqdn format strings. Affected file
4086 lib/silcutil/silcutil.c.
4088 * Added nickname_format and nickname_force_format fields to the
4089 SilcClientParams structure. The first one defines the format
4090 for the nicknames that the library will enforce if the receives
4091 multiple same nicknames. The second one is boolean value and
4092 can be used to force the library to always enforce the format
4093 to the nicknames regardles whether there are multiple nicknames
4094 or not. This configurable formatting was employed to flexibly
4095 support accessing multiple nicknames from the user interface.
4096 The userinterface can now set the nicknames to what ever format
4097 they prefer. Affected file lib/silcclient/silcapi.h.
4099 Added function silc_client_nickname_format to the file
4100 lib/silcclient/idlist.c. It performs the nickname formatting.
4102 Added new field `hostname´ to the SilcClientEntry context.
4103 It holds the hostname of the client. Affected file is
4104 lib/silcclient/idlist.h.
4106 * Irssi SILC Client sets the nicknames in nick@hostn format.
4107 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4108 irssi/src/silc/core/silc-core.c.
4110 The WHOIS printing now also shows both the real nickname and
4111 the formatted nickname so that user knows how to access the
4112 user if there are multiple same nicknames cached. Affected
4113 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4114 printing formatting too to take the hostname now as a separate
4115 argument. The Affected file is
4116 irssi/src/fe-common/silc/modules-formats.[ch].
4118 * Changed the silc_client_get_clients_local to accept the formatted
4119 nickname as argument. It accepts the real nickname too but the
4120 formatted nickname can be used to find the true entry from
4121 multiple entries. Affected file lib/silcclient/silcapi.h and
4122 lib/silcclient/idlist.c.
4124 * Added nickname_format_parse field to the SilcClientParams.
4125 It is a callback function provided by the application to parse
4126 the nickname out of the formatted nickname string. The library
4127 calls it to get the nickname from the formatted string. Since
4128 the application generally knows better the format of the nickname
4129 string it parses it instead of the library, even though library
4130 encodes the formatted string. If the callback function is not
4131 provided then the library will use the string as is. The
4132 affected file is lib/silcclient/silcapi.h.
4134 * All the nickname strings passed to the client library in
4135 commands are now expected to be formatted nickname strings.
4136 If the command does not support the formatted nickname string
4137 it will assume that the sent string is the actual nickname.
4138 Affected file lib/silcclient/command.c.
4140 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4142 * Added public key authentication support to OPER and SILCOPER
4143 commands in the client library. Affected file is
4144 lib/silcclient/command.c.
4146 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Changed the get_auth_methdod client operation to be asynchronous.
4149 It can be async if the application resolves the authentication
4150 method from the server during the negotiation. Added new
4151 SilcGetAuthMeth completion callback that the application will
4152 call after resolving the authentication method.
4154 Added function silc_client_request_authentication_method that
4155 the application can use to resolve the authentication method
4156 from the server. Added also SilcConnectionAuthRequest callback
4157 that the library will call after the server has replied. The
4158 application can call this function if it does not know the
4159 current authentication method.
4161 Affected files are lib/silcclient/client.c and
4162 lib/silcclient/silcapi.h.
4164 * The Irssi SILC client now automatically resolves the authentication
4165 method incase any configuration information is not present (and
4166 currently there never is). The affected file is
4167 irssi/src/silc/core/client_ops.c.
4169 * Fixed public key authentication from the client library.
4170 Affected file lib/silcclient/protocol.c. Changed also the
4171 protocol specification about the public key authentication in
4172 the connection authentication protocol. The actual data to be
4173 signed is now computed with a hash function before signing.
4175 * Fixed the public key authentication from the server as well.
4176 Affected file silcd/protocol.c.
4178 * Removed the mlock()'s from the memory allocation routines.
4179 Affected file lib/silcutil/silcmemory.c. The ./configure does
4180 not check anymore for the mlock(). Affected file is
4183 * Fixed USERS command in server to allow the execution of the
4184 command for private and secret channels if the client sending
4185 the command is on the channel. Affected file silcd/command.c.
4187 * Fixed silc_client_get_clients_local to return the clients
4188 count correctly. It could return wrong value. Affected file
4189 lib/silcclient/idlist.c.
4191 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4194 types. The assembler optimizations seemed not to like 64-bit
4195 data types. The assmebler optimizations thus are now enabled
4196 also for BSD systems as opposed to only enable them for Linux.
4198 * Do not check for threads at all on BSD systems. Affected
4199 file configure.in.pre.
4201 * Removed -n and -h options from the Irssi SILC Client since
4202 they are not used in silc.
4204 * Fixed the prime generation to assure that the first digit
4205 of the generated random number is not zero since our conversion
4206 routines does not like number strings that starts with zero
4207 digit. If zero digit is seen the random number is regenerated.
4208 This caused some corrupted RSA keys when the zero first digit
4209 was met. Affected file lib/silcmath/silcprimegen.c.
4211 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4213 * Fixed WIN32 configuration in the ./configure script.
4214 Fixed to include xti.h on environments that has it.
4215 Patches by Carsten Ilchmann and andrew.
4217 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4219 * Changed the silc_id_create_client_id to be collision
4220 resistant. It is now assured that there cannot be created
4221 two same client ID's. I suspect that some weird bugs in
4222 the server were actually caused by duplicate Client IDs.
4223 Affected file silcd/serverid.[ch]. A router receiving
4224 new ID now also assures and informs the sending server
4225 if the ID caused collision.
4227 * Changed the silc_id_create_channel_id to also assure that
4228 there are no collisions.
4230 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4232 * Statement about ignoring the Mutual Authentication flag when
4233 performing rekey with PFS was a bit misleading. It is ignored
4234 if it was set in the initial negotiation, it cannot be even
4235 set in the rekey. Fixed in the ke-auth draft. Started the
4236 new versions of the protocol drafts in the doc/.
4238 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Fixed a bug in silc_client_command_identify_save when saving
4241 new channel information. The channel name was no duplicated
4242 and caused crash on exit. Affected file is
4243 lib/silcclient/command_reply.c.
4245 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * Fixed the getkey command handling in the server. Send just
4248 empty OK reply to the sender if the key could not be fetched
4249 (but everything else was ok, like the key just was not available).
4250 Changed the public key parameter to optional in the protocol
4251 specs so that empty OK reply can be sent. Affected file
4254 Added a message to Irssi SILC client to tell to user if the
4255 server did not return a public key.
4257 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4259 * Fixed a channel key regeneration bug. It registered new
4260 timeout tasks exponentially until all system resources were
4261 used. Affected file silcd/server.c.
4263 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4265 * Added the SILC Document generator to the scripts/silcdoc.
4266 It can be used to generate the Toolkit Reference Manual out
4267 of the source tree. Internally it will also use the RoboDoc
4268 generator now imported in util/robodoc.
4270 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4272 * Added couple of return's in rekey protocol if error orccurred
4273 during the protocol. The execution must be terminated.
4274 Affected file silcd/protocol.c. Also, terminate the protocol
4275 always with timeout.
4277 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4279 * The client's Client ID was created initally from the wrong
4280 nickname (it could have been in format nick@host) in the
4281 silc_server_new_client. Affected file silcd/packet_receive.c
4283 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4285 * Added some SILC_LOG_ERROR's to various error conditions
4286 if client could not be added to ID cache. Affected files
4287 silcd/packet_receive.c and silcd/server.c.
4289 * When client's sock->user_data is freed, NULL also the
4290 client->router and client->connection pointers. Added check
4291 for these pointers being NULL to various places around the
4292 code. Affected file silcd/server.c.
4294 * Added client->data.registered == TRUE checks to various
4295 places around the code to assure that unregistered client's
4296 are not handled when it is not allowed. Affected file
4299 * Added `bool registered' fields to all
4300 silc_idlist_[server|client]_get_* routines to indicate whether
4301 the fetched client needs to be registered or not. Affected
4302 file silcd/idlist.[ch].
4304 * Add your own entry as registered to the ID cache in the
4305 server. Affected file server.c.
4307 * Fixed a bug in silc_server_new_server. The SilcServer was
4308 set as the new server's context instead of SilcServerEntry.
4309 This naturally caused some weird bugs.
4311 * Added "updated" field the SilcChannelEntry which indicates
4312 the time since the channel entry was last accessed. This
4313 can be used to determine whether it is necessary to
4314 announce the channel after backup resuming protocol.
4315 Affected files silcd/idlist.[ch].
4317 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4319 * Do not delete the channel rekey task when adding it
4320 for in silc_server_create_channel_key.
4322 * Changed the silc_server_create_channel_key to return
4323 TRUE or FALSE to indicate the success of the channel key
4326 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4328 * Fixed MSVC++ project files and added missing files to
4329 Makefiles under win32/.
4331 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4333 * Do not add TCP_NODELAY flag if the operating system
4334 does not have it defined. Affected files are
4335 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4337 * Fixed buffer overflow from Irssi SILC Client. Affected
4338 file irssi/src/fe-common/core/themes.c.
4340 * Fixed double free in client library in the file
4341 lib/silcclient/client.c when disconnecting from server.
4343 * Applied double free patch from cras to Irssi SILC client.
4344 Affected files irssi/src/core/[modules/expandos].c
4346 * Fixed the disconnection handling to Irssi SILC Client.
4347 The application must call silc_client_close_connection
4348 in ops->connect client operation in case of failure of
4349 the connection. Affected file is
4350 irssi/src/silc/core/client_ops.c.
4352 * Do not set sock->protocol to NULL in the function
4353 silc_client_close_connection after executing the protocol's
4354 final callback since the sock might not be valid anymore.
4355 Affected file lib/silcclient/client.c.
4357 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4359 * Do not enable SILC_THREADS if the linking with libpthread
4360 did not happen. Affected file configure.in.pre.
4362 * Added notion to protocol specification that server must
4363 verify the sent authentication payload with CMODE when
4364 setting the channel founder key. Implemented it to the
4365 server. Affected file silcd/command.c.
4367 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4369 * Added _EXTRA_DIST SILC distribution variable to the
4370 distributions file. It is used to conditionally add extra
4371 files or directories to the specific distribution. Affected
4372 files ./prepare, Makefile.am.pre and distributions.
4374 Removed the `_' from the start of the distribution names.
4377 * Added README.WIN32 for instructions to compile the Toolkit
4380 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Fixed a double free in disconnection in the server. Affected
4383 file is silcd/server.c.
4385 * Fixed the lib/silcske/groups.c to work now also with GMP
4386 MP library. The string conversion did not work when using
4387 specific base and the base is indicated in the string as well.
4389 * Created win32/ directory which now includes MSVC++ specific
4390 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4391 It will appear only in the toolkit distribution
4393 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4395 * Changed the key material distribution function in case when
4396 the hash output is too short. The data is now concatenated
4397 a bit differently than it used to. Made the change to the
4398 SKE protocol specification.
4400 * Added better GMP detection to configure.in.pre. A patch
4403 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4405 * Fixed a minor bug in SKE that might cause some problem on
4406 some platforms. Affected file lib/silcske/silcske.c.
4408 * Added the cookie checking for initiator in the SKE. It checks
4409 that the responder returns the sent cookie unmodified. The
4410 affected file is lib/silcske/silcske.c. Added new SKE
4411 error type INVALID_COOKIE that can be sent during the
4412 negotiation. Fixed some memory leaks as well.
4414 * Added the "invalid cookie" error message to Irssi SILC client's
4417 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4419 * Added `task_max' field to the SilcClientParams to indicate
4420 the maximum tasks the scheduler can handle. If set to zero,
4421 default values are used. Affected file lib/silcclient/silcapi.h.
4423 * Fixed memory leaks in silc_client_close_connection. Affected
4424 file lib/silcclient/client.c.
4426 * Added silc_client_del_client_entry to client library to free
4427 all memory of given client entry. Affected file is
4428 lib/silcclient/idlist.[ch].
4430 * Added new functions silc_client_del_channel and
4431 silc_client_del_server to delete channel and server entries.
4432 Affected file lib/silcclient/[silcapi.h/idlist.c].
4434 * Removed silc_client_del_client_by_id from silcapi.h.
4436 * Fixed the INFO command to return the server's own info
4437 correctly when querying by Server ID. Affected file is
4440 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4442 * Removed the non-blocking settings in WIN32 code in the
4443 silc_sock_[read/write] and added SleepEx instead. Affected
4444 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4445 of input data is now checked with FIONREAD and ioctlsocket.
4447 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4449 * Call silc_schedule_task_del_by_context in the
4450 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4451 Affected file lib/silccore/silcprotocol.c.
4453 * Call silc_protocol_cancel for active protocols in the
4454 silc_server_close_connection if the funtion
4455 silc_server_free_sock_user_data has not been called.
4456 Affected file silcd/server.c.
4458 * Generic tasks cannot be deleted using the del_by_fd
4459 task deleting function since generic tasks does not match
4460 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4462 * Added a notion to SILCOPER help file that the SILCOPER works
4463 only on router server, not on normal server.
4465 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Added for WIN32 support for the new scheduler as well.
4468 Affected file lib/silcutil/win32/silcwin32schedule.c.
4470 * Fixed the SHA1 implementation to work on various platforms.
4472 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4474 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4475 API. It is part of the scheduler now. Everything else is
4476 as previously but some functions has changed their names.
4477 Checkout the lib/silcutil/silcschedule.h for the interface.
4478 Updated all applications to use the new interface. Affected
4479 files are lib/silcutil/silcschedule.[ch].
4481 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4483 * Found a bug in the SKE implementation. The HASH value,
4484 specified by the protocol, was not computed correctly. The
4485 public key of the responder was not added to the computation
4486 even though it is mandatory. Affected file lib/silcske/silcske.c.
4487 This unfortunately causes incompatibilities with older
4488 clients and servers.
4490 * Added WIN32 specific network init and uninit functions:
4491 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4492 the Winsock2. Affected file lib/silcutil/silcnet.h and
4493 lib/silcutil/win32/silcwin32net.c.
4495 * Set the socket always to nonblocking mode on WIN32 after
4496 reading data or writing data. Affected file is
4497 lib/silcutil/win32/silcwin32sockconn.c.
4499 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4501 * Fixed various compilation problems under WIN32. Affected
4502 files lib/silcutil/win32/silcwin32thread.c and
4503 lib/silcutil/win32/silcwin32schedule.c.
4505 * Removed all _internal.h #includes from public header
4506 files. Internal headers must never be included from
4509 Removed also the lib/silcske/payload_internal.h file.
4511 * All include files that may be needed (public and some others
4512 included by the public headers) by application developers are
4513 now copied to the ./includes directory. It does not copy any
4514 internal headers. Affected file Makefile.defines.pre and all
4515 Makefile.am's under lib/ and subdirs.
4517 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4519 * Do not change the ~/.silc directory's permissions automatically.
4520 Affected file irssi/src/silc/core/clientutil.c.
4522 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4524 * Do not cancel the protocol in silc_server_close_connection
4525 it might cause recursion. Now cancelled in the function
4526 silc_server_free_sock_user_data. Affected file silcd/server.c.
4528 * Fixed the silc_server_remove_clients_by_server to regenerate
4529 the channel keys correctly finally. Added also new function
4530 silc_server_remove_clients_channels to actually do it.
4531 Affected file silcd/server.c.
4533 * Fixed the silc_server_new_channel to not crash by giving
4534 wrong router to the new channel. Affected file is
4535 silcd/packet_receive.c.
4537 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4540 which is given as argument to the silc_client_alloc now.
4541 It can be used to configure the client and set various parameters
4542 that affect the function of the client.
4544 * The USERS command in server did not check whether the channel
4545 is private or secret. Affected file silcd/command.c.
4547 * Added new argument to the USERS command in protocol specification.
4548 The USERS command now can take the channel name as argument
4549 as well. Added support for this in client and server and
4550 updated the protocol specs.
4552 * Completed the GETKEY command in client. It can be now used
4553 to fetch also servers public key not only some clients.
4554 Affected files lib/silcclient/command[_reply].c.
4556 * Added silc_client_get_server to return server entry by the
4557 server name. Affected files lib/silcclient/silcapi.h and
4560 * Redefined the IDENTIFY command in protocol specification to be
4561 more generic. It now can be used to query information about
4562 any entity in the SILC Network, including clients, servers and
4563 channels. The query may be based either the entity's name
4564 or the ID. Added support for this in both client and server.
4566 Affected files silcd/command.c and lib/silcclient/command.c
4567 and command_reply.c.
4569 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4570 the _from_client and _from_server functions. Affected file
4573 * Added silc_client_get_channel_by_id_resolve to the file
4574 lib/silcclient/silcapi.h to resolve channel information by
4575 its ID. Added also silc_client_get_channel_by_id that
4576 does not resolve it from the server.
4578 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4580 * Added SilcServerEntry context into the client library
4581 to represent one server. The INFO command now allocates
4582 these to save the resolved server info. For now on the
4583 client library will also keep information about servers,
4584 connected and resolved with INFO.
4586 The INFO command now allocates the SilcServerEntry context
4587 and saves the server info there. The COMMAND_REPLY in
4588 the INFO now returns the parameters to application in
4589 same order as defined in the protocol specification.
4591 The entries are cached in the client->server_cache.
4593 * The INFO command is now issued after received the Client ID
4594 from the server. Affected file lib/silcclient/client.c.
4596 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4597 to the application as the mode changer might be server.
4598 It is guaranteed that NULL is not returned anymore to the
4599 application. Affected file lib/silcclient/client_notify.c.
4601 The ID Type is now also passed to the application so that
4602 it can check whether the returned entry is SilcClientEntry
4605 Added new function silc_client_get_server_by_id to return
4606 the server entry by ID. Affected files are the
4607 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4609 * Do not create the channel in the Irssi SILC Client when issuing
4610 the JOIN command but when received the sucessful JOIN command
4611 reply. Otherwise the channel might get created even though we
4612 could not join it. The Affected file is
4613 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4615 * Fixed a channel joining bug in router. The router must also
4616 check the channel modes, invite and ban lists etc. when serving
4617 the JOIN command sent by normal server. Affected file is
4618 silcd/command.c. The router now resolves the client's
4619 information from the server who sent the JOIN command if it
4620 does not know it, and processes the JOIN command only after
4623 * Changed the SilcCommandCb to take new argument; void *context2.
4624 Affected file lib/silccore/silccommand.h
4626 The second argument in the command callbacks in the server now
4627 includes the SilcServerCommandReplyContext if the command was
4628 called as pending command callback from the command reply.
4629 Otherwise it is NULL. When called as pending the status of the
4630 command reply will be checked and if it was erronous the
4631 error will be sent to the original sender of the command.
4632 This way the client always receives the error messages even
4633 though the server was actually the one who received the error
4634 when it resent the command to router, for example. Affected
4635 files silcd/command[_reply].[ch].
4637 * Fixed sending WHOWAS command's error message to client if
4638 the requested client could not be found. It was missing.
4641 * Changed the CMODE and CUMODE commands reply arguments in the
4642 protocol specification. The Channel ID is now sent in both
4643 of the commands to identify the channel. Implemented this
4644 new feature to the client and server. Affected files
4645 lib/silcclient/command_reply.c and silcd/command.c.
4647 * Made better checks for invite and ban lists in the JOIN
4648 command in server. Affected file silcd/command.c.
4650 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4652 * The server now performs the incoming host IP/DNS lookup
4653 using the silc_socket_host_lookup and thus does not block
4654 the server anymore. Affected file silcd/server.c.
4656 * Completed the multi-thread support for SILC Scheduler in
4657 the lib/silcutil/silcschedule.c.
4659 * Fixed the configure.in.pre to detect the pthread correctly
4662 * Fixed a deadlock in silc_task_queue_wakeup in the file
4663 lib/silcutil/silctask.c.
4665 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4667 * Added new function silc_schedule_wakeup that is used in
4668 multi-threaded environment to wakeup the main thread's
4669 schduler. It needs to be used when a thread adds a new task
4670 or removes a task from task queues. After waking up, the
4671 scheduler will detect the task queue changes. If threads
4672 support is not compiled in this function has no effect.
4673 Implemented the wakeup mechanism to both Unix and WIN32
4674 systems. Affected files are lib/silcutil/silcschedule.[ch],
4675 lib/silcutil/unix/silcunixschedule.c and the
4676 lib/silcutil/win32/silcwin32schedule.c.
4678 * Added new function silc_task_queue_wakeup to wakeup the
4679 scheduler by the specified task queue. Affected file
4680 lib/silcutil/silctask.[ch].
4682 * The silc_socket_host_lookup_start now wakes up the scheduler
4683 after adding the timeout task. Affected file is
4684 lib/silcutil/silcsockconn.c.
4686 * The silc_socket_host_lookup is synchronous now if the threads
4687 support is not compiled in. However, the callback is still
4688 called asyncronously through the scheduler, anyway. Affected
4689 file lib/silcutil/silcsockconn.c.
4691 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4693 * Added new function silc_socket_host_lookup to perform
4694 asynchronous IP and FQDN lookups for the socket connection.
4695 Affected files lib/silcutil/silcsockconn.[ch].
4697 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4700 that may or may not compile the mutex support in.
4702 Changed the silc_mutex_alloc interface. It allocates the
4703 mutex now to the sent pointer and returns TRUE or FALSE.
4705 Affected file lib/silcutil/silcmutex.h.
4707 * Wrote the SILC Task Queue interface to support multi-threads.
4708 Affected file lib/silcutil/silctask.[ch].
4710 * Wrote the SILC Scheduler to support multi-threads. Affected
4711 file lib/silcutil/silcschedule.c.
4713 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4715 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4716 in lib/silcutil/win32/.
4718 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4720 * Defined SILC Mutex API and SILC Thread API and implemented
4721 them for Unix. Affected files are
4722 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4723 lib/silcutil/unix/silcunixmutex.c and
4724 lib/silcutil/unix/silcunixthread.c.
4726 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4728 * Fixed the silc_server_remove_clients_by_server's channel
4729 key re-generation. The hash table handling was incorrect
4730 and would not work with many channels. Affected file is
4733 * Fixed some memory leaks around the server code.
4735 * Rewrote the silc_server_get_users_on_channel to support IPv6
4736 based Client ID's. Affected file silcd/server.c.
4738 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4739 specification. However, a separate document must be written
4740 to define the detailed signing procedure and the payload
4741 associated with the flag. Defined the flag to the
4742 lib/silccore/silcchannel.h as well.
4744 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4746 * Changed the dynamic tables to static size tables in the
4747 lib/silccrypt/silchmac.c.
4749 * Removed GCC dependencies from the code. A patch by cras.
4751 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4753 * Do not show the error "Error receiving packet bla bla"
4754 in server if it really was not an error (-2 means that reading
4755 is pending). Affected file silcd/server.c.
4757 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4759 * Fixed a possible crash in silc_server_remove_clients_by_server
4760 in silcd/server.c. Fixed there also some memory leaks.
4762 * Fixed the silc_idlist_replace_client_id. It could replace
4763 wrong key in the hash table. Affected file silcd/idlist.c.
4765 * Do not check whether there are global users on the channel
4766 if the channel->global_users is FALSE. Affected functions
4767 silc_server_remove_from_one_channel and
4768 silc_server_remove_from_channels in silcd/server.c. Also,
4769 do not check if the removed client is local as we can be
4770 sure that global client was not removed from the channel
4771 and checking for global users is not needed.
4773 * The silc_server_remove_clients_by_server now re-generates
4774 the channel keys correctly for those channels that had
4775 clients removed from them. Affected file silcd/server.c.
4777 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4779 * Found the reason of random crashes in the server. We weren't
4780 ignoring the SIGPIPE signal (which can be sent in write())
4781 and it crashed the server. Affected file silcd/silcd.c.
4783 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4785 * Assure that sock->user_data is not NULL in the function
4786 silc_server_packet_send in silcd/packet_send.c.
4788 * Disconnect the remote connection if it could not be added
4789 to any ID lists in the server. The affected file is
4792 * Check in silc_server_packet_send[_real/dest] that the
4793 socket is not disconnecting and ignore the data if it is.
4794 Affected file silcd/packet_send.c.
4796 * Define inline to __inline on native WIN32 compilation.
4797 Affected file includes/silcwin32.h.
4799 * Added some explicit type casts for inline code since MSVC
4800 require them. Affected files lib/silcutil/silcbuffer.h,
4801 lib/trq/silcdlist.h and lib/trq/silclist.h.
4803 * Print warning in log files from now on if the packet
4804 decryption fails. Affected file silcd/server.c.
4806 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4808 * Changed the `say' client operation's interface to accept
4809 new `type' argument to indicate the type of the message sent
4810 by the library. The application may filter the library's
4811 messages according the type. The affected file is the
4812 lib/silcclient/silcapi.h.
4814 * Added two new functions to lib/silcclient/silcapi.h:
4815 silc_client_del_client and silc_client_del_client_by_id.
4816 Affected file lib/silcclient/idlist.c.
4818 * Moved the clientincludes.h from includes/ to silc/ and
4819 serverincludes.h from includes/ to silcd/.
4821 * The modes for the CMODE and CUMODE are now passed as
4822 uint32 for application with COMMAND_REPLY. The affected
4823 file is lib/silcclient/command_reply.c.
4825 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4827 * /WHOIS without arguments shows client's own information.
4828 Affected file lib/silcclient/command.c.
4830 * Changed PING to not accept any arguments. The specs
4831 says that client can ping only the connected server so
4832 requiring an argument is not needed. Affected file is
4833 lib/silcclient/command.c.
4835 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4837 * Fixed a fatal bug in private message sending and reception
4838 encryption and decryption when using private message keys.
4839 The implementation was incorrect and did not follow the
4840 specification. It causd that some of the message were
4841 lost since it did not use the sending and receiving keys
4842 as the protocol suggests. This has been fixed and will cause
4843 incompatibilities with older clients when sending private
4844 message encrypted with private message keys. Affected files
4845 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4846 and various other in Irssi SILC Client.
4848 Added `responder' boolean argument to the functions
4849 silc_client_add_private_message_key[_ske] to indicate when
4850 the key is added as responder or initiator of the key
4853 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4855 * Removed the silc_ske_check_version function and created
4856 a SilcSKECheckVersion callback. Added also a function
4857 silc_ske_set_callbacks that is now used to set all SKE
4858 callbacks. The callback functions are not given to
4859 the SKE functions anymore, but this function is used to
4862 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4864 * Added `silc_version' argument to the silc_client_alloc
4865 to define the version of the application for the library.
4866 The library will use the version string to compare it
4867 against the remote host's (usually a server) version
4868 string. Affected file lib/silcclient/silcapi.h
4870 * Added the KE protocol context to Key Agreement context
4871 in client library so that we can abort the SKE if it
4872 is in process when we get timeout. Affected file is
4873 lib/silcclient/client_keyagr.c.
4875 * Do not resolve the client ID forever if it returns in the
4876 first time that such client does not exist. This was done
4877 for example with private message. Affected file is
4878 lib/silcclient/client_prvmsg.c.
4880 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4882 * Do not add regex.h for WIN32. The affected file
4883 includes/silcincludes.h.
4885 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4886 not work yet 100%. It generates the DLL's automatically
4887 when compiling with --with-win32 under cygwin.
4889 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4891 * lib/contrib/regex.c is not compiled on WIN32.
4893 * Added silc_net_get_socket_opt function to the
4894 lib/silcutil/silcnet.h.
4896 * Added includes/silcwin32.h for WIN32 specific includes
4899 * Do not use ptime structure or any of the posix process
4900 functions on WIN32 in lib/silccrypt/silrng.c.
4902 * Added silc_gettimeofday to provide generic function
4903 for struct timeval on all platforms. Added the function
4904 to lib/silcutil/silcutil.h.
4906 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4908 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4909 library as they clearly belong there. As a plus side we
4910 can make the actual socket connection routines platform
4913 Added also new generic function silc_socket_read and
4914 silc_socket_write (that used to be silc_packet_[read/write].
4915 The implementation of these are platform specific.
4917 * Added WIN32 specific routines of silc_socket_[read/write]
4918 to lib/silcutil/win32/silcwin32sockconn.c.
4920 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4922 * Added preliminary support for native WIN32 compilation under
4923 cygwin (using the -mno-cygwin option for GCC) to the
4924 ./configure.in.pre. The --with-win32 now prepares the
4925 compilation for native WIN32.
4927 * Rewrote the SILC Scheduler interface in the file
4928 lib/silcutil/silcschedule.h. The scheduler is now context
4929 based and does not have anymore any global static scheduler.
4930 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4931 and created lib/silcutil/win32 directory for WIN32 based
4934 * Added Unix specific network routines to the
4935 lib/silcutil/unix/silcunixnet.c and the old
4936 lib/silcutil/silcnet.c includes now only generic routines.
4938 Added WIN32 specific network routines to the
4939 lib/silcutil/win32/silcwin32net.c.
4941 * Added Unix specific utility functions from the
4942 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4944 * Added WIN32 SILC Scheduler to the file
4945 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4948 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4950 * Do not handle JOIN notify in the server if the target client
4951 is not registered (idata->registered == FALSE). The affected
4952 file is silcd/packet_receive.c.
4954 * Update the nickrec->founder in event_cumode in the Irssi SILC
4955 client. Affected file irssi/src/silc/core/silc-channels.c.
4957 * Fixed the CUMODE_CHANGE notify handling in the server when
4958 server and router are announcing their clients on channels.
4959 Now the mode changes are saved and notified correctly. The
4960 affected file is /silcd/packet_receive.c.
4962 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4963 They really did not replace the cache entry in the ID Cache.
4964 Now they do that. Affected file silcd/idlist.c.
4966 * Fixed the KICK notify handling in the Irssi SILC client to
4967 update the channel records so that the kicked client does not
4968 appear to be on the channel. The affected file is
4969 irssi/src/silc/core/silc-channels.c.
4971 * Always update the conn->current_channel when executing command
4972 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4974 * Fixed the KILL notify handling in Irssi SILC client to remove
4975 the killed client on all channels.
4977 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Fixed the silc_parse_command_line to remove extra spaces
4980 from the start and end of the arguments. Affected file is
4981 lib/silcutil/silcutil.c.
4983 * Cancel and free any active protocol in the function
4984 silc_server_close_connection. Affected file silcd/server.c.
4986 * Cancel and free any active protocol in the function
4987 silc_client_close_connction. Affected file is
4988 lib/silcclient/client.c.
4990 * Do not execute the KILL command for clients that are in
4991 history (ie. they are not in the network). Affected file is
4994 * Fixed KILL notify handling, client does not crash anymore.
4995 Affected file irssi/src/silc/core/silc-channels.c.
4997 * Reduced the default packet buffer size from 2048 to 1024 in
4998 lib/silccore/silcpacket.c.
5000 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5001 counter to the SKE context that is incresed when the SKE library
5002 performs async operation outside the library. If the outside
5003 process frees the SKE context and FREED status will be set
5004 and the library will detect after the sync operation that the
5005 libary is freed. The affected files are
5006 lib/silcske/silcske[_status].[ch].
5008 * Resolve the client entry information in the function
5009 silc_client_channel_message to assure that NULL pointer is not
5010 passed as client entry to the application. */
5012 * Fixed the task timeout calculation to assure that there is
5013 never negative timeouts. The affected file is
5014 lib/silcutil/silcschedule.c.
5016 * Fixed the channel user mode notification sending in server.
5017 It was sent point-to-point to the router (or to server by router)
5018 but it needs to be destined to a channel. The routines now
5019 supports sending the channel user mode notifys to the channels
5020 when announcing clients and channels. Affected files are
5021 silcd/server.c and silcd/packet_receive.c.
5023 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5024 It did not actually replace the old channel entry in the cache.
5025 Affected file lib/silcclient/client_notify.c.
5027 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Fixed a possible crash in silc_packet_send_prepare. It now
5030 assures always that there is enough space in the buffer and
5031 at the tail area of the buffer (for MAC).
5033 Fixed the inbound buffer reallocation in silc_packet_read.
5034 It was old code and did not handle the reallocation correctly.
5037 The affected file is lib/silccore/silcpacket.c.
5039 * Fixed buffer overflow in silc_parse_nickname in the file
5040 lib/silcutil/silcutil.c.
5042 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * make install generates new server keys only if there is not
5047 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5050 Added check that if the NOREPLY is set then we will not send
5051 the away message. This avoids infinite loop of away messages
5052 if both clients are away. The affected file is
5053 lib/silcclient/client_prvmsg.c.
5055 * Fixed client crash if /NICK was given without arguments.
5056 Affected file lib/silcclient/command.c.
5058 * Server does not send the invite list in INVITE command back
5059 to the client if the list was not altered. Added this notion
5060 to the protocol spec as well. Affected file silcd/command.c.
5062 Fixed possible crash in INVITE command by checking the
5063 value of silc_server_get_client_route command.
5065 * Fixed the INVITE notify type handling. The arguments are now
5066 taken in correct order and client does not crash. The affected
5067 file is irssi/src/silc/core/silc-channels.c.
5069 Removed the "Inviting xxx to channel" message from the
5070 client library away and let the application handle it.
5071 Affected file lib/silcclient/command.c. Added that message
5072 to Irssi SILC client's message formats.
5074 * Fixed CMODE command crash in client. It now checks the
5075 amount of arguments correctly and does not crash. The affected
5076 file is lib/silcclient/command.c.
5078 * Do not create new channel automatically in silc_channels_join
5079 but check whether the channel by that name already exists.
5080 Affected file irssi/silc/core/silc-channels.c.
5082 * Do not send the SERVER_SIGNOFF to router if the disconnected
5083 entity was the router. Affected file silcd/server.c.
5085 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5086 SILC client as it was missing from there.
5088 Added the handling of the KICK notify to the Irssi SILC client
5089 as it was missing. Added "you have been kicked" message to
5090 Irssi SILC client's message modules formats.
5092 Added the handing of the KILL notify to the Irssi SILC client
5093 as it was missing. Added the kill message module formats
5096 The affected file is irssi/src/silc/core/silc-channels.c.
5098 * The router did not save the channel mode the server announced.
5099 Affected file silcd/packet_receive.c.
5101 * Fixed a possible crash in INFO command in server. If the
5102 server did not provide the server info it crashed. Affected
5103 file silcd/command.c.
5105 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Fixed the GETKEY command in the server to check also the
5108 global list. Otherwise the GETKEY would not work correctly
5109 in normal SILC server. Affected file silcd/command.c.
5111 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Fixed GETKEY crash, it crashed if the command did not succseed.
5115 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5118 is now real and not just an macro interface to GMP.
5120 Removed the entire GMP from the source tree and imported new
5121 NSS MPI library instead. Reason for removing GMP is that it is
5122 extremely large and compiles extremely slow. The NSS MPI
5123 is only a few files and compiles in less than 10 seconds.
5124 The speed is also about the same as GMP. The MPI is imported
5125 to lib/silcmath/mpi.
5127 If the system has GMP installed we will still use the GMP.
5128 If it is not then the NSS MPI will be compiled.
5130 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Merged a long nickname (127 characters long) crash bugfix from
5133 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5135 * Merged a freed memory reference bugfix from Irssi CVS tree.
5136 Affected file irssi/src/core/commands.c.
5138 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Added the server's public key sving and verification to the
5141 server when performing the SKE. This was missing and the
5142 remote server's (or router's) public key was accepted without
5143 checking whether we have it previously or trust it at all.
5144 Affected file silcd/protocol.c.
5146 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Check in the silc_server_timeout_remote if protocol is active
5149 and make sure that the protocol's final callback is called so
5150 that all memory if freed. Affected file silcd/server.c.
5152 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * silc_server_whois_send_reply crashed the server if the nickname
5155 was 127 characters long. Affected file silcd/command.c.
5157 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added sanity check to the silc_server_new_client. If the hostname
5160 is provided inside username then check that the provided hostname
5161 really is the same as the resolved one. If the hostname was not
5162 resolved then check it from the public key. Affected file is
5163 silcd/packet_receive.c.
5165 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5166 if the server disconnected us and the connection is not valid
5167 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5169 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5170 the library to the lib/silcutil/silcutil.[ch].
5172 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Close log file after open. Affected file
5175 lib/silcutil/silclog.c.
5177 * Check whether sock == NULL in silc_client_send_packet and return
5178 if it is. Affected file lib/silcclient/silcclient.c.
5180 * Check rec->entry == NULL in the Irssi SILC Client before
5181 sending the channel message. Affecte file is
5182 irssi/src/silc/core/silc-servers.c.
5184 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Merged a splitted window bugfix from Irssi CVS tree. The
5187 affected file is irssi/src/fe-text/textbuffer-view.c.
5189 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5190 It did not print nickname.
5192 * Improved the distributions system a bit.
5194 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5197 irssi/src/fe-text/gui-window.c.
5199 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5200 to in-active server. The affected file is
5201 irssi/src/silc/core/client_ops.c.
5203 * Resolve the client in USERS command reply if the entry does
5204 not have username resolved. The affected file is
5205 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5206 command to WHOIS command to really resolve stuff. The USERS
5207 is not used any more in any critical section so WHOIS can
5208 be used even though it might be slower than IDENTIFY.
5210 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5213 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Changed the protocol API a bit more consistent in the
5216 lib/silccore/silcprotocol.[ch].
5218 * Changed the following headers to ROBODoc format:
5220 lib/silccore/silcpayload.h
5221 lib/silccore/silcprotocol.h
5222 lib/silccore/silcsockconn.h
5224 All core library headers are now formatted.
5226 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Fixed a bug in Irssi SILC client; do not show that you are
5229 server/router operator if you really are not. Affected file is
5230 irssi/src/silc/core/client_ops.c.
5232 * Renamed silc_command_free_payload to silc_command_payload_free.
5233 Affected file lib/silccore/silccommand.h
5235 * Added silcmath.h to include the prototoypes of various routines
5236 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5239 * Changed the following headers to ROBODoc format:
5241 lib/silccore/silcchannel.h
5242 lib/silccore/silccommand.h
5243 lib/silccore/silcid.h
5244 lib/silccore/silcidcache.h
5245 lib/silccore/silcmode.h
5246 lib/silccore/silcnotify.h
5247 lib/silccore/silcpacket.h
5248 lib/silcmath/silcmath.h
5250 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added checking to the server code not to start the server if
5253 ciphers and stuff are not configured properly. Affected files
5254 silcd/serverconfig.[h] and silcd/server.c.
5256 * Changed the layout of the header files of the public interfaces
5257 in the SILC libraries. The new layout supports ROBODoc
5258 documentation tool (and some others) so that it is easy to create
5259 a library reference manual. All the other headers and source
5260 code must still follow the CodingStyle document. Also source
5261 code must not include these ROBODoc stuffs, only the headers.
5262 Furthermore, all public interface headers must now be named
5263 by using `silc' prefix, example: silcapi.h, silccipher.h.
5264 Some files were renamed due to this. All the other headers
5265 must not be used as public interfaces. I will update the
5266 CodingStyle document later. Changed following headers, so far:
5268 lib/silcclient/silcapi.h
5269 lib/silccore/silcauth.h
5270 lib/silccore/silcprivate.h
5271 lib/silccrypt/silcdh.h
5273 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Removed silc_client_packet_send_flush from the client library
5278 as it is not needed. Affected file lib/silcclient/client.[ch].
5280 * Added printing of message of unresolved authentication method
5281 to the Irssi SILC client. Added it to the module formats.
5282 Removed the same message from the client library.
5284 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Added new distribution feature, DISTLABEL. Every distribution
5287 can define own preprocessor label that can be used in the
5288 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5289 file distributions, acconfig.h.pre and prepare.
5291 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added Makefile.defines_int to include the actual definitions
5294 for Makefile.defines.in. Tested the new distribution system,
5295 created distributions and tested installation.
5297 * Added AWAY message printing to the Irssi SILC client. Added
5298 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5300 * Added SCONNECT command to call the SILC's CONNECT command.
5301 Cannot use CONNECT directly since Irssi uses that internally.
5302 Affected file irssi/src/silc/core/silc-servers.c.
5304 Added ACTION local command. It is same as ME command but takes
5305 the channel as mandatory argument.
5307 Rewrote some of the Irssi's help files to suite for SILC
5310 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added Makefile.defines[.in] that should for now on be included
5313 in all Makefile.am file in the source tree. That file includes
5314 all common compilation definitions for SILC source tree.
5316 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Minor changes to the ./prepare script to change the package
5319 name according the distribution name to the configure.in.
5321 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Created new distribution system. Added file `distributions'
5324 that defines all the distributions that can be created out of
5325 the SILC source tree. The ./prepare script now reads that
5326 file to determine how to prepare the distributions. The
5327 first argument to the ./prepare is the name of the distribution
5328 and second is the version of the distribution. If given
5329 without arguments it creates the default (toolkit) distribution
5330 with the default version (defined in ./prepare).
5332 All Makefile.am files that are subject to the distributions
5333 are now named as Makefile.am.pre. These are ./Makefile.am
5334 and lib/Makefile.am. Others may be changed later.
5336 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Added invite list, ban list, some key management and connection
5339 error message printing to module formats in the Irssi SILC client.
5341 * Added new silc_client_set_away_message to set the away message
5342 that is back to the person who sent private message. The
5343 affected file lib/silcclient/silcapi.h and the
5344 lib/silcclient/client_prvmsg.c.
5346 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Fixed the private message sending in the Irssi SILC client,
5349 added local command KEY to the Irssi SILC client.
5351 Added key management and key agreement message formats to the
5352 irssi/src/fe-common/silc/module-formats.[ch].
5354 Added USERS (alias WHO) printing, server/router operator
5355 indication and LIST command printing to the module formats.
5357 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Fixed channel joining notify handling, cumode notify handling
5360 from Irssi SILC client.
5362 * Added SILC specific module-formats to the Irssi SILC client so
5363 that SILC specific message hilighting, colors etc is possible.
5364 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5366 Added channel mode, channel user mode, actions, notices,
5367 whois and whowas printing to the the module-formats.c.
5369 * Fixed a bug in channel deletion in the server. The channel
5370 is not left to the cache even if the channel founder auth mode
5371 is set when there are no users anymore on the channel. Affected
5372 file silcd/server.c.
5374 * The silc_net_localhost now resolves the entire hostname including
5375 the domain name. Affected file lib/silcutil/silcnet.c.
5377 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Changed the ask_passphrase client operation to be ascynchronous.
5380 It has now a completion callback and a context that the
5381 application must call after it has got the passphrase from
5382 the user. Affected files lib/silcclient/silcapi.h,
5383 lib/silcclient/protocol.c, lib/silcclient/command.c and
5386 Added SilcAskPassphrase callback that the application calls
5387 to deliver the passphrase to the library.
5389 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5390 The public key verification and especially a certificate
5391 verification is asynchronous procedure.
5393 Added new SILC_SKE_STATUS_PENDING status to indicate the
5394 request is pending and a callback will be called to finalize
5397 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5398 indicate that remote end did not send its public key (or
5399 certificate), even though we require it. Added check for this
5400 condition in the SKE. This was a security bug, now fixed.
5402 Defined new SilcSKEVerifyCbCompletion callback that is called
5403 when the verification process is completed.
5405 The affected files lib/silcske/silcske_status.h and
5406 lib/silcske/silcske.[ch].
5408 * Changed the verify_public_key client operation to be async
5409 as well. Defined SilcVerifyPublicKey callback that is used to
5410 indicate the success of the public key verification process.
5412 Changed the server and client to use the new async client
5415 * Changed the Irssi SILC client's internal scheduler to be called
5416 twice as many times as it used to be. As a result the client
5417 should be a bit faster now. Affected file is
5418 irssi/src/silc/core/silc-core.c.
5420 * Added support to Irssi SILC client of asynchronous public key
5421 verification and passphrase inquiry. Affected file is
5422 irssi/src/silc/core/silc-core.c.
5424 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Do not say "You have left channel %s" in client library.
5427 Moved it to the application. Affected files are
5428 lib/silcclient/command.c and silc/client_ops.c.
5430 * Fixed silc_client_get_clients. Command context was not
5431 duplicated and was freed memory in the callback. Affected
5432 file lib/silcclient/idlist.c.
5434 * Do not say "you are now talking..." on JOIN command in the
5435 client library. The appliation must handle it.
5437 * Do not say ".. changed topic to" in command reply in the
5438 client libary. The application must handle it.
5440 * Fixed TOPIC command sending in the client library.
5442 * Fixed a memory leak in silc_client_command_free in the file
5443 lib/silcclient/command.c.
5445 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Imported a modified version of Irssi client to the source tree.
5448 The Irssi will be used to create a new client called
5449 Irssi SILC. Imported to irssi/.
5451 Added silc_core_init_finish function to the Irssi. Affected
5452 file irssi/configure.in.
5454 A lot changes in the Makefile.ams around the irssi tree.
5456 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Do not rehash if the new size is same as the old size of the
5459 hash table, in the silc_hash_table_rehash*. The affected file
5460 lib/silcutil/silchashtable.c.
5462 * Replaced hash_table_del_by_context calls from the server
5463 (when channel->user_list and client->channels) to the
5464 hash_table_del as it is sufficient and faster.
5466 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Added silc_hash_table_list, silc_hash_table_get and the
5469 SilcHashTableList structure to provide an alternative way to
5470 traverse the hash table. The affected files are
5471 lib/silcutil/silchashtable.[ch].
5473 * Changed the server's idlist routines to use the hash table
5474 routines to optimize the code.
5476 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Replaced the client entry's `channel' list and channel entry's
5479 `user_list' list to hash tables for optimized lookup. Changed
5480 the code to use the hash table interface around the code.
5481 Affected file lib/silcd/idlist.[ch].
5483 * Added `auto_rehash' boolean argument to the function
5484 silc_hash_table_alloc to indicate whether the hash table should
5485 auto-rehash when it thinks is appropriate time. It will
5486 increase the hash table size if the there is twice as much
5487 entries in the table than the size of the table, and will
5488 decrease the size if there are twice as less entries than
5489 the size of the table.
5491 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5495 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * silc_idcache_purge_by_context deletes the entry now by context
5498 as it is supposed to do. Affected file lib/silccore/idcache.c.
5500 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5501 client is not anymore valid (WHOWAS givens the info) and not
5502 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5504 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Removed the `data' and `data_len' arguments from the ID Cache
5507 interfaces and added `name' argument. ID Cache does not handle
5508 anymore the binary data only a names associated with given ID.
5510 * When hashing a Client ID with silc_hash_id the entire ID is
5511 not hashed anymore, instead only the hash of the Client ID is
5512 hashed. This way we can access the Client ID from the cache
5513 with Client ID but with the hash of the ID (which is a hash of
5514 the nickname) as well without any difference in performance.
5516 Added also silc_idcache_find_by_id_one_ext to do one on one
5517 searching when we have the actual ID. Added also function
5518 silc_hash_client_id_compare. The affected files are
5519 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5521 * When hashing the name associated with a ID it is always done
5522 in lowercase. This way we can access the cache without worrying
5523 about case-sensitivity, even though, for example nicknames are
5526 * Fixed a bug in server with channel message sending. It put
5527 wrong ID type as destination ID. The affected file
5528 silcd/packet_send.c.
5530 * silc_idcache_del_by_context now deletes from all hash tables
5531 by context. Affected file lib/silccore/idcache.c.
5533 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Changed the client library to use the new ID Cache interface.
5536 Changes around the source tree.
5538 * Added silc_hash_table_rehash_ext to rehash with specific
5539 hash function. Affected file lib/silcutil/silchashtable.[ch].
5541 * Added silc_hash_string_compare to compare two strings in the
5542 hash table. Affected file lib/silcutil/silcutil.[ch].
5544 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added new function silc_idcache_del_by_context into the
5547 lib/silccore/idcache.[ch].
5549 * Changed the server's ID list routines to use the new ID Cache
5550 interface. Changes around the source tree.
5552 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Added silc_hash_table_del[_by_context]_ext functions in to the
5555 lib/silcutil/silchashtable.[ch].
5557 Removed silc_hash_table_find_all* routines and added new
5558 silc_hash_table_find_foreach to replace them.
5560 Added silc_hash_table_replace_ext function as extended
5561 replacing function. Separated the simple hash table interface
5562 from the extended hash table interface in the file
5563 lib/silcutil/silchashtable.h.
5565 * Fixed minor bugs and changed it to use some of the new
5566 hash table functions in lib/silccore/idcache.c
5568 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Added new function silc_hash_table_find_all to return all keys
5571 in the hash table by the specified key. As the hash table is
5572 collision resistant it also makes it possible to have several
5573 duplicate keys in the hash table. This function may be used to
5574 find all of the keys from the hash.
5576 Added user_context arguments to the SilcHashFunction,
5577 SilcHashCompare and SilcHashDestructor to deliver user specified
5580 Added new fuctions silc_hash_table_find[_all]_ext to do
5581 extended lookup with specified hash and compare functions and
5582 specified user contexts.
5584 Added new function silc_hash_table_add_ext to add the key
5585 with specified hash function and user context.
5587 Added new function silc_hash_table_foreach to traverse all
5588 entrys in the hash table. Added SilcHashForeach callback
5591 Added new function silc_hash_table_del_by_context to delete
5592 the entry only if the context associated with the key matches.
5594 Affected files are lib/silcutil/silchashtable.[ch].
5596 * Removed silc_hash_[server/client/channel]_id and added just
5597 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5598 silc_hash_id_compare to compare two ID's using as the hash table
5599 comparison function. Added also silc_hash_data to hash
5600 binary data and silc_hash_data_compare to compare it.
5602 * Removed silc_idlist_find_client_by_hash as it is not needed
5603 anymore. Affected file silcd/idlist.[ch].
5605 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5606 to use internally the SilcHashTable. The new ID Cache is a lot
5607 faster than the old one. Some of the ID Cache interface was also
5608 rewritten and obsolete and stupid functions were removed.
5610 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Added entry_count field to the SilcHashTable to keep the number
5613 of the entries in the table. Implemented the function
5614 silc_hash_table_rehash. Added new function
5615 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5617 Fixed a minor bug in silc_hash_table_free.
5619 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5620 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5621 into the lib/silcutil/silcutil.[ch].
5623 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Implemented a collision resistant hash table into the
5626 lib/silcutil/silchashtable[ch]. See the header and the source
5627 for the SilcHashTable API.
5629 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Merged dotconf version 1.0.2 into lib/dotconf.
5633 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Do not compile anything in lib/silcsim/* if the SIM support
5636 is not enabled. The tree should now compile without problems
5639 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Compiled the SILC under cygwin. Compiled and tested briefly
5642 without problems. More tests needed. The SIMs didn't compile
5645 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5647 * Fixed possible crash in silc_get_username in the
5648 lib/silcutil/silcutil.c.
5650 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Fixed a va_arg in silc/client_ops.c.
5654 * Oops, RC5 routines were named AES and caused some problems
5655 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5657 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added new SilcIDIP structure into the lib/silccore/id.h and
5660 replaced the old `ip' fields from all SILC ID's to that type.
5661 This is a step towards IPv6 support.
5663 The silc_id_get_len takes now the ID as an extra argument.
5664 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5665 both IPv4 and IPv6 based ID's.
5667 The affected files are lib/silccore/id.[ch] and other files
5668 around the tree using these routines.
5670 * Removed the ID length arguments in server from various
5671 silc_server_send_notify_* routines -> they are not needed
5674 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Fixed memory leak in silc_encode_pem_file in the file
5677 lib/silcutil/silcutil.c.
5679 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Check minor version as well in the SKE. Affected files are
5682 silcd/protocol.c and lib/silcclient/protocol.c.
5684 * Added --identifier option to the server so that an identifier
5685 can be when creating the public key for the server. Affected
5686 file is silcd/silcd.c.
5688 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5689 lib/silccrypt/silcpkcs.c.
5691 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Register default ciphers and stuff when using -C option with
5694 the server. Affected file sildc/silcd.c.
5696 * Put back the servers public key filename format, it is better
5697 than the new one. For now, the client keys are saved with the
5698 new filename format. The affected file silc/client_ops.c.
5700 * Implemented the Cipher API for the rest of the ciphers that
5701 did not implement it or implemented it the wrong way.
5703 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Register default ciphers and stuff when using the -S option
5706 in the client. Affected file silc/silc.c. Same also when
5707 creating new key pair with -C option.
5709 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Fixed the silc_verify_public_key client operation function to
5712 save the public keys differently. The fingerprint is now
5713 used as filename and not the hostname. This way also the
5714 client keys are saved uniquely and not with hostnames. The
5715 affected file is silc/client_ops.c.
5717 * Trimmed the silc_hash_fingerprint function to remove extra
5718 whitespaces from the end of the fingerprint. The affected
5719 file is lib/silccrypt/silchash.c.
5723 * Added silc_cipher_register_default function to register all
5724 default ciphers. It can be used when configuration files
5725 does not exist and the application does not want any specific
5726 ciphers in any specific order.
5728 The SilcDList is now used as silc_cipher_list dynamically
5729 allocated cipher list. Removed the static list all together
5730 and now all ciphers must be allocated to the dynamic list.
5731 The silc_cipher_alloc routine was changed to check only the
5734 All silc_cipher_* routines that used to return int returns
5737 The affected files lib/silccrypt/silccrypt.[ch].
5739 * The same thing was done to silc_hash_* as for silc_cipher_*
5740 routines. Affected files lib/silccrypt/silchash.[ch].
5742 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5743 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5744 Added also silc_pkcs_[un]register[_default] functions.
5745 Removed the data_context from the PKCS API.
5747 * Added silc_hmac_register_default function to register default
5748 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5749 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5750 to unregister all hmacs at once.
5752 * Register the default ciphers, hash functions, PKCSs and HMACs
5753 if client's configuration file does not exist. The affected
5756 * The client did not load the hash functions from the SIM
5757 modules at all. Added support for this. Affected file is
5758 silc/clientconfig.c.
5760 * When decoding public key with silc_pkcs_public_key_decode, check
5761 the supported algorithm only if PKCS are registered. Affected
5762 file lib/silccrypt/silcpkcs.c. The same was done with the
5763 silc_pkcs_private_key_decode.
5765 * Fixed the SILC List routines to keep the list always in order.
5766 It used to change the list's order when traversing the list but
5767 not it preserves the order. Affected file lib/trq/silclist.h.
5769 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added the client library to use the SilcSocketConnection's
5772 reference counter (by silc_socket_dup) to prevent the bug that
5773 the socket object may be freed underneath async operation.
5775 * The name resolv library checking fixes in the configure.in.pre.
5778 * Created new version of the protocol drafts for future
5779 development. The -03 drafts are the ones that will be changed
5780 in the trunk now and the -02 will remain as they are.
5782 * Send list of CUMODE notifys to the router when announcing
5783 the channel users to the router. Affected file silcd/server.c.
5784 If the router receiving channel founder CUMODE for a channel
5785 that already has channel founder it will send CUMODE notify
5786 to the sender to remove the channel founder rights from the
5787 announced client. Affected file silcd/packet_receive.c.
5789 * The CUMODE notify may now use Server ID as well as the entity
5790 who changes the mode. Updated protocool specs.
5792 * Updated INSTALL and README files.
5794 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * New web pages in the http://silc.pspt.fi. The pages was
5801 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Implemented the [DenyConnectin] config section in the server.
5804 Added silc_server_config_denied_conn to check whether incoming
5805 connection is denied. Affected file silcd/serverconfig.[ch].
5807 * Do not check the ports when checking the incoming configuration
5808 data if the port is 0, meaning any. Affected file is
5809 silcd/serverconfig.c.
5811 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Fixed buffer overflow in silc_string_compare in the file
5814 lib/silcutil/silcutil.c.
5816 * Fixed double free in silc_server_command_leave in the file
5819 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Fixed the version checking in the server. Affected file is
5824 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Fixed the configuration data fetching when accepting new
5827 connections in the server. Affected file silcd/server.c.
5829 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Added `sender_entry' argument to the function
5832 silc_server_packet_relay_to_channel so that we can check
5833 whether some destination actually belongs to the same route
5834 the sender belongs (ie, we must not resend the packet to the
5835 sender). Affected file silcd/packet_send.[ch].
5837 * Added `servername' field to the SilcClientEntry in the server
5838 to hold the name of the server where client is from. Affected
5839 file is silcd/idlist.h.
5841 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Moved the channel message encrypting in the router betwen
5844 router connections from silc_server_channel_message to the
5845 silc_server_packet_relay_to_channel since we want to check
5846 whether we have anybody channel before encrypting anything.
5847 Affected files silcd/packet_[receive/send].c.
5849 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Fixed the [AdminConnection] server config section to support
5852 multiple entries. Affected file silcd/serverconfig.c.
5854 * Added support into the server to check the validity of the
5855 incoming connection before executing any KE or authentication
5858 * The connection configuration is now saved to the KE and
5859 connection auth protocol contexts and not fetched anymore in
5860 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5862 * The local hosts listenning address and port is also resolved
5863 now when starting the server. We want to have the socket object
5864 to include the real address and port for the listener. Added
5865 new function silc_net_check_local_by_sock into the files
5866 lib/silcutil/silcnet.[ch].
5868 * Fixed a broadcast bug in server -> do not broadcast if we
5871 * Fixed a routing bug. Do not route broadcast packets ever.
5872 Broadcast packets must be processed always and not routed since
5873 they may be destined to some other host than yourself and thus
5874 would get routed without no good reason. Affected file is
5877 * Added function silc_server_config_is_primary_route to check
5878 whether primary router connection has been configured (a router
5879 configuration that we are initiating). If there is not, we
5880 will assume that there is only two routers in the SILC network
5881 and we will use the incoming router connection as our primary
5882 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5884 * Changed the order of the broadcasting. Broadcast _after_ the
5885 packet has been processed not before. Affected file is
5888 * Fixed a [ClientConnection] parsing bug. The port was never
5889 parsed correctly thus resulting to port 0. Affected file
5890 silcd/serverconfig.c.
5892 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5893 argument and did not set the broadcast packet flag. Affected
5894 file silcd/packet_send.c. Fixed same bug in the function
5895 silc_server_send_notify as well.
5897 * If we receive NEW_ID packet for our own ID in the server, ignore
5900 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Removed the nickname from the Private Message Payload.
5905 Updated the code and the protocol specs.
5907 * Updated protocol specs for submitting to the IETF.
5909 * Tweaked the Random Number Generator a bit. Affected file
5910 lib/silccrypt/silcrng.c. Exported a new function
5911 silc_rng_[global]_add_noise which can be used to add more
5914 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Do not parse packets with different timeout when protocol
5917 is active -> may cause problem with rekey. Affected file
5920 * When server receives signoff notify it must not create
5921 new channel key if the client is on any channels since the
5922 sender of the signoff notify will create it.
5924 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added printing of error messages during SKE protocol from the
5927 failure packet sent by server during SKE. Affected file
5930 * Removed the client's failure_callback handling with timeout
5931 and handle it immediately when received.
5933 * The SKE library returned wrong type in SUCCESS and FAILURE
5934 packets. They must be 32 bit MSB not 16 bit MSB.
5936 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Ok, rewrote the logic of the re-key and now it seems to work.
5939 I tested it on high traffic with frequent re-keys without
5940 problems. Added hmac_receive (and renamed hmac to hmac_send)
5941 in SilcClientConnection in lib/silcclient/client.h and
5942 in SilcIDListData in silcd/idlist.h. Also, removed the
5943 SilcPacketParserContext's cipher and hmac fields as they are
5944 not needed anymore and actually caused some problems when
5945 the ciphers and hmac's changed underneath the packet parser.
5947 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * If re-key protocol is active then process the incoming packets
5950 synchronously since we must assure that icoming packets encrypted
5951 with the old key is processed before the new keys is set to
5952 use. This is true other packets than for REKEY packets.
5953 Affected file silcd/server.c. The same was done to client library
5954 as well, affected file lib/silcclient/client.c.
5956 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Fixed bug in client and server to accept the force send if
5959 the packet is send from silc_[server/client]_packet_process
5960 function. Otherwise the packets are never delivered, oops.
5962 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Disable force sending of packets when REKEY protocol is active.
5965 We must assure that no packet is sent directly when rekey is
5966 performed. All packets must be sent through packet queue.
5967 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5968 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5969 function is silc_[server/client]_packet_send_real to check
5972 * Replaced the SIM paths from example config files to
5973 /usr/local/modules. Also, make install creates now
5974 /usr/local/silc/logs directory to hold all the SILC server
5977 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Made the configure.in.pre work on Solaris. Patch by salo.
5981 * Made all ciphers compatible with non-x86 machines. Defined
5982 CBC mode macros into lib/silccrypt/ciphers_def.h.
5984 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Fixed the make install.
5988 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * When MAC computation fails the silc_packet_decrypt returned 0
5991 even though it was supposed to return -1. Fixed this. The
5992 affected file is lib/silccore/silcpacket.c.
5994 * Do not replace the config files in /etc/silc (in make install)
5995 if they already exist. Affected file ./Makefile.am.
5997 * Do not send re-key packets immediately but through packet queue.
5998 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6000 * Changed silc_net_check_host_by_sock to return FALSE if the
6001 IP/DNS could not be resolved. Though, it returns the IP address
6002 now even if it could not resolve it (but returns also FALSE).
6003 Affected file lib/silcutil/silcnet.[ch].
6005 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Added silc_pkcs_decode_identifier to decode the public key's
6008 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6009 Added also silc_pkcs_free_identifier. Added also new context
6010 SilcPublicKeyIdentifier.
6012 * Added -S option to the silc client. It is used to dump the
6013 contents of the specified public key file.
6015 * Changed the PKCS api to return the public key length when
6016 setting the public key.
6018 * Fixed a fatal bug in the public and private key file loading.
6019 Affected file lib/silccrypt/silcpkcs.c.
6021 * Execute the packet parsing for client with zero (0) timeout
6022 if the protocol is active. Affected file silcd/server.c.
6024 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Made the key generation options to the silcd program. Added
6027 -C option, equivalent to client's option.
6029 * Added new [ServerKeys] config section to the server. It
6030 configures the server's public and private key.
6032 * Defined generic Public Key Payload into the protocol
6033 specification to send specific type of public keys and
6036 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6037 public key or certificate.
6039 * Implemented the GETKEY command to the server and to the
6040 client library and on user interface.
6042 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Made preliminary `make install' work.
6046 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Added SilcServerRekey context into silcd/idlist.h.
6050 * Added the PFS support as defined in the specification to the
6051 SKE protocol. Affected files lib/silcske/*.c.
6053 * Added `ske_group' field to the SilcServerRekey context to hold
6054 the number of the SKE group that is used with PFS in re-key.
6055 Affected file silcd/idlist.h.
6057 * Added PFS re-key support to the server. Affected file is
6060 * Added silc_protocol_cancel to cancel execution of the next
6061 state of the protocol. Affected file is
6062 lib/silccore/silcprotocol.[ch].
6064 * Added the re-key support with and without PFS to the client
6065 library. Re-key is performed once in an hour, by default.
6067 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6068 Added silc_client_rekey_callback and silc_client_rekey_final.
6069 Affected files are lib/silcclient/protocol.[ch] and
6070 lib/silcclient/client.[ch].
6072 * Removed the `hmac_key' and `hmac_key_len' fields from the
6073 SilcClientConnection structure; not needed. Affected file is
6074 lib/silcclient/client.h.
6078 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Do not ask whether user wants to use the negotiated private key
6081 for private messages, just use it. Affected file is
6082 silc/local_command.c.
6084 * Added `send_enc_key' and `enc_key_len' fields to the
6085 SilcIDListData structure since they are needed in the re-key
6086 phase. Affected file is silcd/idlist.[ch].
6088 * Implemented the simple re-key protocol into the server.
6089 Affected files silcd/server.c and silcd/protocol.[ch]. The
6090 re-key will be performed once in an hour, by default.
6092 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6093 Added silc_server_rekey, silc_server_rekey_callback and
6094 silc_server_rekey_final.
6096 * Removed Tunneled flag from the protocol. Updated the code
6097 and the specifications.
6099 * Adde `pfs' field to the SilcIDListData to indicate whether
6100 the PFS is to be performed in the re-key. Affected file is
6103 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6106 int64 of at least the xintXX size. If void * is less that 4
6107 bytes uint32 * will be used. Defined bool as boolean.
6109 * Changed _ALL_ unsigned long and unsigned int to uint32,
6110 unsgined short to uint16 in the source tree.
6112 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6113 not handle clients that has entry->data.registered == FALSE.
6114 They are not in the network anymore. Affected file is
6117 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Implemented the sending of the SERVER_SIGNOFF notify in the
6120 server. Affected file is silcd/server.c.
6122 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6123 Added also silc_notify_payload_encode_args into the
6124 lib/silccore/silcnotify.[ch].
6126 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6127 Affected file silcd/packet_receive.c.
6129 * Implemented the SERVER_SIGNOFF notify handling in the client
6130 library. Affected file lib/silcclient/client_notify.c. Also,
6131 implemnted the printing of the SERVER_SIGNOFF info to the
6132 application. Affected file silc/client_ops.c.
6134 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6135 if the deleting was successful. Affected file silcd/idlist.[ch].
6137 * Added support for public key authentication in the connection
6138 authentication protocol in the client library. Affected file
6139 lib/silcclient/protocol.c.
6141 * Changed the server's silc_idlist_get_clients_by_* interface
6142 to support already allocated array so that new entries may be
6143 added to pre-allocated array. Affected file silcd/idlist.[ch].
6144 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6145 and command replies.
6147 * All command reply functions in the server now calls the
6148 pending command callback even if error occured. This way the
6149 error will be delivered to the client as well. Affected files
6150 silcd/command.c and silcd/command_reply.c.
6152 * Fixed INFO command to return local server's info if no server
6153 was provided. Affected file lib/silcclient/command.c.
6155 * Removed RESTART command for good. Updated the code and the
6158 * Rewrote parts of the task system. It is a bit simpler now.
6159 Removed unsued task priorities. The affected files are
6160 lib/silcutil/silctask.[ch].
6162 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Moved the USERS printing from the library to the application.
6165 Affected files lib/silcclient/command.c and silc/client_ops.c.
6167 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Added channel key re-key support. The re-key is perfomed
6172 only by the router and is done once in an hour. Added `rekey'
6173 field to the SilcChannelEntry in the server. Affected files
6174 silcd/server.c and silcd/idlist.h.
6176 * Added silc_task_unregister_by_context into the file
6177 lib/silcutil/silctask.[ch].
6179 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Added SILC_UMODE_GONE mode to indicate when the client is not
6182 present in the SILC network. Added also support to the local
6183 command AWAY that will set this mode. Added support of showing
6184 "xxx is gone" in WHOIS command. The USERS command shows the
6185 gone status as well.
6187 * Fixed setting server and router operator privileges in the
6188 server's UMODE command. Affected file silcd/command.c.
6190 * Merged the SKE KE1 and KE2 payloads into one payload. The
6191 new KE payload is equivalent to the old KE2 payload.
6193 Cleaned up the SKE Start Payload parsing. It now uses the
6194 simple buffer unformatting to do the parsing. A lot faster
6197 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6198 to the SKE that is used to indicate whether both of the SKE
6199 parties should perform authentication. By default only the
6200 responder performs authentication. By setting this flag also
6201 the initiator must do authentication. By default it is unset
6202 since in normal SKE case, client to server connection, only
6203 the responder should do authentication. When doing SKE between
6204 two clients both should perform authentication. Updated the
6205 code and the protocol specs.
6207 * A little fix to IDENTIFY command in the server. Search the
6208 client first by hash not nickname. Affected file is
6211 * Fixed the silc_client_close_connection to support closing
6212 the client to client connections wihtout deleting too much
6213 data. Affected file lib/silcclient/client.c.
6215 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6216 are received if protocol used to be active but is not anymore
6217 the application would crash due to NULL pointer dereference.
6218 Affected files silcd/server.c and lib/silcclient/client.c.
6220 * Added `hash' field to the SilcClientConnection to include
6221 the hash function negotiated in the SKE protocol.
6223 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6224 to set the channel founder authentication data. A client can
6225 claim the founder rights later by providing the authentication
6226 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6227 This way the channel founder can regain the channel founder
6228 privileges even it is left the channel. This works only on
6229 local server and the client must be connected to the same
6230 server to be able to regain the founder rights. Updated the
6231 protocol specs accordingly.
6233 Added support to the CMODE command in the client to set the
6234 founder auth data. Read the README to see how to set it.
6236 Added support to the CUMODE command to claim the founder
6237 rights. Read the README to see how to do it.
6239 Added support for the founder authentication to the Channel
6240 Entry in the server. Affected file silcd/idlist.h.
6242 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6243 server's CMODE command. Affected file silcd/command.c.
6245 * Added the following new functions into lib/silccore/silcauth.[ch]:
6246 silc_auth_get_method and silc_auth_get_data.
6248 * The server now saves the remote hosts public key to the
6249 SilcIDListData pointer. Affected file silcd/protocol.c.
6251 * The normal server now does not remove the channel entry from
6252 the cache if the founder authentication data is set. It used
6253 to remove it if the founder was the last one on the channel on
6254 the server and left the channel. The auth data is saved and
6255 if the channel is re-joined later the old entry is used with
6256 the old auth data. Affected files silcd/command_reply.c and
6259 * Removed the `pkcs' field from the SilcIDListData structure
6260 in the server; it is not used. Affected file silcd/idlist.h.
6262 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Fixed packet processing on slow links. Partial packets were
6265 never re-processed because the incoming data buffer was cleared
6266 by the application. Application must not directly clear the
6267 sock->inbuf, the packet processing routines handle it. Fixed
6268 this in client library and in server.
6270 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Fixed the WHOIS and IDENTIFY send reply function to really
6273 check whether to send list or just one entry. Affected file
6276 * Cleaned up the LEAVE command's channel key distribution. The
6277 affected file silcd/command.c.
6279 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6280 can enforce the channel mode as well. In that case the ID
6281 includes the ID of the server. The code now enforces the
6282 mode change if the router have different mode than the server.
6284 * The notify client operation with CMODE_CHANGE notify can now
6285 return NULL client_entry pointer if the CMODE was not changed
6286 by client. Application must check for this.
6288 * Added <Server ID> argument to INFO command to support server
6289 info fetching by Server ID.
6291 * Added silc_server_announce_get_channel_users to get assembled
6292 packets of channel users of the specified channel. Affected
6293 file silcd/server.[ch].
6295 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6296 was freed underneath the ID Cache.
6298 * Re-announce clients when the server received CHANNEL_CHANGE
6299 notify from the router. Affected file silcd/packet_send.c.
6301 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6304 crashed since it did not handle the fact that there is no cipher
6305 called "3" and didn't check the error condition. Now fixed.
6307 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6308 flag. It can be used to send message requests.
6310 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Implemented the RESTART command in the client.
6314 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6315 notice type messages. Added notice printing to the user
6318 * The channel keys are not re-generated if the channel's mode
6319 is PRIVKEY, ie private key on the channel exists. Affected
6320 files silcd/server.c and silcd/command.c.
6322 * Fixed a little bug in channel message delivery when channel
6323 private keys are set in the server. Affected file is
6324 silcd/packet_send.c.
6326 * Changed the setting on channel->on_channel = TRUE from the
6327 silc_client_save_channel_key to the JOIN command reply. The
6328 key payload is not received if the private channel key is set.
6329 Affected file lib/silcclient/command_reply.c and the
6330 lib/silcclient/client_channel.c.
6332 * When the CMODE_CHANGE notify is sent and the channel private
6333 key mode is removed the channel key must be re-generated in
6334 other cells as well. Added this support for the router in the
6335 silcd/packet_receive.c.
6337 * Added new local command NOTICE to send notice message on
6338 channel. Affected file silc/local_command.[ch].
6340 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Added new local command ME to the client. It is used to send
6343 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6344 some action. Affected file silc/local_command.[ch].
6346 * Changed channel_message and private_message client operations
6347 to deliver the message flags to the application. Added also
6348 the `flags' arguments to the silc_client_send_channel_message
6349 and silc_client_send_private_message functions. Affected file
6352 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Redefined the Private Message Payload to support private message
6355 keys and to support the new private message flags. Updated
6356 the protocol specs. Flags makes it possible to have for example
6357 CTCP style messages.
6359 * Added new type SilcPrivateMessagePayload and defined an API
6360 for it in the lib/silcclient/silcprivate.[ch].
6362 * Tested private message private keys successfully. Tested the
6363 private message key set, unset and list commands with the new
6366 * Redefined the Channel Message Payload to include the channel
6367 message flags (equal with private message flags) to support
6368 for example CTCP style messages.
6370 * Defined some of the message (for channel and private message)
6371 flags. Updated the protocol specs and added the flags to the
6372 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6374 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Added SilcKeyAgreementStatus type to the key agreement routines
6377 to indicate the current status and error if one occured.
6378 The status types are defined in the lib/silcclient/silcapi.h.
6380 * Added new local command KEY that is used to set and unset private
6381 keys for channels, set and unset private keys for private messages
6382 with remote clients and to send key agreement requests and
6383 negotiate the key agreement protocol with remote client. The
6384 key agreement is supported only to negotiate private message keys,
6385 it currently cannot be used to negotiate private keys for channels,
6386 as it is not convenient for that purpose.
6388 * Fixed a minor pending callback setting bug in the function
6389 silc_client_get_client_by_id_resolve, now the function works.
6390 Affected file lib/silcclient/idlist.c.
6392 * Added function silc_net_get_local_port to get local bound
6393 port by socket. Added to lib/silcutil/silcnet.[ch].
6395 * Added `sockets' and `sockets_count' fields to the SilcClient
6396 object. They hold the sockets of the listenning sockets in
6397 the client. Listenning sockets may be for example the key
6398 agreement server. Affected file lib/silcclient/client.[ch].
6399 Added functions the silc_client_add_socket and the
6400 silc_client_del_socket. They are exported to the application
6403 * Added ~./silc/clientkeys to support other client's public keys.
6405 * Renamed verify_server_key client operation to verify_public_key
6406 and added one argument to indicate the type of the connection
6407 (server, client etc.).
6409 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added silc_server_connection_auth_request to handle the
6412 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6413 silcd/packet_receive.[ch].
6415 * Added silc_server_send_connection_auth_request into the
6416 silcd/packet_send.c to send the connection auth request packet.
6418 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6421 * Fixed the public key authentication in responder side in the
6422 server. The `auth_data' pointer includes the SilcPublicKey
6423 not the path to the public key. Affected file silcd/protocol.c.
6425 * Implemented the public key authentication in the initiator side
6426 in the server. Affected file silcd/protocol.c.
6428 * Removed the [RedirectClient] config section from the server
6429 configuration. Is not needed and I don't want to implement it.
6431 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6433 * Cleaned up the CMODE command in the server. It now works
6434 correctly and supports all the modes defined in the protocol.
6435 Affected file is silcd/command.c.
6437 * Added `hmac_name' field to the SilcChannelEntry in the server
6438 to hold the default HMAC of the channel. It can be set when
6439 creating the channel (with JOIN command). Affected files
6442 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6443 type to indicate the change of the current cipher and hmac
6444 on the channel. Client can safely ignore the <cipher> argument
6445 (if it chooses to do so) since the CHANNEL_KEY packet will
6446 force the channel key change anyway. The <hmac> argument is
6447 important since the client is responsible of setting the new
6448 HMAC and the hmac key into use.
6450 * Fixed the CMODE command in the client library as well.
6452 * Tested CMODE command in router environment successfully.
6454 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Show the version of the remote client (or server) when connecting
6457 to the server. It is logged to the log file. Affected file
6458 is silcd/protocol.c.
6460 * Fixed the KILLED notify handling in the client library. The
6461 client must be removed from all channels when receiving the
6464 Also, do not remove the client entry when giving the KILL
6465 command but when the KILLED notify is received.
6467 * Removed silc_idlist_find_client_by_nickname from the server.
6468 Not needed anymore. Affected files silcd/idlist.[ch].
6470 * Implemented the CHANNEL_CHANGE notify type handling to the
6471 server. Affected file silcd/server.c.
6475 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Added silc_server_send_notify_invite to send the INVITE
6478 notify between routers.
6480 * Implemented the INVITE command correctly to the server.
6482 * Implemented the INVITE notify type handling in the server.
6484 * Implemented the INVITE command to the client library and on the
6487 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Added function silc_server_get_client_resolve to find the
6490 client entry by ID from all ID lists and then resolve it
6491 (using WHOIS) if it cannot be found. Affected file is
6494 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Implemented the BAN command to the client library.
6498 * The JOIN command in the server now checks the invite list
6501 * Changed the silc_command_reply_payload_encode_va and the
6502 silc_command_payload_encode_va to support that if argument is
6503 NULL it ignores and checks the next argument. Affected file
6504 lib/silccore/silccommand.c.
6506 * Added silc_server_send_notify_ban to send the BAN notify
6507 type between routers.
6509 * Chaned the silc_notify_payload_encode to support that if
6510 argument is NULL it ignores and checks the next argument.
6511 Affected file lib/silccore/silcnotify.c.
6513 * Tested ban lists in router environment successfully.
6515 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Implemented BAN command to the server, in silcd/command.[ch].
6519 * Removed the BAN and INVITE_LIST modes from the CMODE command
6522 * Added function silc_string_match to regex match two strings.
6523 Affected files lib/silcutil/silcutil.[ch].
6525 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Redefined parts of the SilcChannelEntry in the server to support
6528 the new ban and invite lists.
6530 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Redefined the INVITE command. The same command can be used to
6533 invite individuals to the channel but also to manage the invite
6534 list of the channel (to add to and remove from the invite list).
6535 Updated the protocol specs.
6537 * Added new command SILC_COMMAND_BAN that can be used to manage
6538 the ban list of the channel. Updated the protocol specs.
6540 * Removed the channel modes: the SILC_CMODE_BAN and the
6541 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6542 in the CMODE command. The equivalent features are now available
6543 using INVITE and BAN commands. Updated the protocol specs.
6545 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6546 in the network about change in the current ban list. The notify
6547 type is not used by the client.
6549 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6550 support the invite lists.
6552 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Added new function silc_string_regexify that converts string
6555 including wildcard characters into regex string that can
6556 be used by the GNU regex library. Added into the file
6557 lib/silcutil/silcutil.[ch].
6559 Added silc_string_regex_combine to combine to regex strings
6560 into one so that they can be used as one regex string by
6561 the GNU regex library. Added into the file
6562 lib/silcutil/silcutil.[ch].
6564 Added silc_string_regex_match to match two strings. It returns
6565 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6567 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Imported GNU regex to the soruce tree into lib/contrib.
6570 Fixed some compiler warning from the regex.c.
6572 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Fixed MOTD command in the server to work in router environment.
6576 * Fixed the MOTD command in the client library to support
6577 the server argument in the command.
6579 * Added `nickname_len' argument to the silc_idlist_add_client
6580 in the server, as the `nickname' argument may be binary data
6583 * Added silc_idlist_get_channels to return all channels from
6586 * Implemented LIST command to the server. Affected file is
6589 * Implemented the LIST command to the client library and on the
6592 * Added [<user count>] argument to the LIST command reply.
6593 With private channels the user count is not shown.
6595 * Updated TODO and README.
6597 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * The client entry's data.registered must be TRUE even with
6600 global client entry on global client list. The data.registered
6601 is used to check whether the client is anymore in the network,
6602 for example with WHOWAS command so it must be valid.
6604 * Fixed the WHOWAS command in the server. It now actually works
6605 in router environment. Added function into silcd/command_reply.c
6606 silc_server_command_reply_whowas_save.
6608 * Added silc_idlist_purge function to the silcd/idlist.c
6609 to periodically purge the ID Cache.
6611 * Fixed INFO command in the server. It works now in router
6612 environment. Added <server name> argument to the INFO command
6613 reply. Updated the protocol specs.
6615 * Fixed minor bug in silc_idcache_purge to not purge if the
6616 expire value is zero.
6618 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6619 they were buggy because of the WHOWAS information.
6621 * Fixed local command MSG to handle the async resolving of
6622 the remote client properly. It used to fail the first MSG.
6623 Affected file silc/local_command.c.
6625 * Added `data_len' field to SilcIDCache context.
6627 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Update TODO. Todo in commands in the server.
6631 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6634 used by routers as broadcast packet to inform other routers
6635 about the changed user mode.
6637 Implemented the notify handling in the server. Affected file is
6638 silcd/packet_receive.c. Added the function
6639 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6641 * Added new generic Channel Payload and deprecated the New Channel
6642 Payload. The New Channel Payload is now the generic Channel
6645 * Added new argument `mode' to the silc_server_send_new_channel
6646 as it is required in the Channel Payload now.
6648 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6649 and created a new and real SilChannelPayload to represent the
6650 new generic Channel Payload. Implemented the encode/decode
6651 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6653 * Added silc_server_get_client_channel_list to return the list
6654 of channels the client has joined for WHOIS command reply.
6655 Affected file silcd/server.[ch].
6657 * Implemented the channel list sending in the WHOIS command reply
6658 in server and in the client.
6660 Implemented the channel list displaying on the user interface
6661 as well. Affected file silc/client_ops.c.
6663 * Added silc_channel_payload_parse_list to parse list of Channel
6664 Payloads. It returns SilcDList list of SilcChannelPayloads.
6665 Client for example can use this function to parse the list of
6666 channels it receives in the WHOIS command reply. The caller
6667 must free the list by calling silc_channel_payload_list_free.
6668 Affected files lib/silccore/silcchannel.[ch].
6670 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Added one new argument <user mode> to the WHOIS command reply
6673 to return the mode of the user in SILC. Updated the protocol
6676 Implemented it to the server and client.
6678 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed the mode printing on the user interface on joining.
6681 Affected file silc/client_ops.c.
6683 * Implemented the UMODE command and user modes in general to the
6684 client library and to the user interface.
6686 * Implemented the UMODE command to the server.
6688 * The server now sends UNKNOWN_COMMAND error status if client sends
6689 unknown command. Affected file silcd/command.c.
6691 * All server commands now handle the command identifier the right
6692 way when sending the command reply to the client. The client can
6693 use to identify the command replies with the identifier.
6695 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added silc_server_get_client_route to resolve the route to
6698 the client indicated by the client ID. Affected file is
6701 * Added silc_server_relay_packet as general function to relay
6702 packet to arbitrary destination. This deprecates functions
6703 like _send_private_message_key, _relay_notify etc. Affected
6704 file is silcd/packet_send.[ch].
6706 Removed silc_server_send_key_agreement,
6707 silc_server_send_private_message_key and
6708 silc_server_packet_relay_notify functions from the file
6709 silcd/packet_send.[ch].
6713 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6714 server. Affected file silcd/packet_receive.[ch].
6716 * Implemented the KILL command to the client. Implemented the
6717 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6718 Affected files lib/silcclient/command[_reply].c and
6719 lib/silcclient/client_notify.c. Implemented the KILL notify
6720 printing in the user inteface.
6722 * Fixed a lot silc_parse_nick memory leaks from the client
6723 library in the file lib/silcclient/command.c.
6725 * Changed the silc_server_send_notify_on_channels's `sender'
6726 argument from SilcSocketConnection to SilcClientEntry to
6727 check the sender as entry and not as connection object and not
6728 to send to the client provided as argument. The affected file
6729 is silcd/packet_send.[ch].
6731 * The notify packets that are destined directly to the client used
6732 to not to be processed by the server. Now changed that and the
6733 server processes all notify packets. After relaying the packet
6734 to the client the notify packet is processed in the server.
6736 * The silc_server_free_client_data now checks whether there is
6737 pending outgoing traffic for the client and purges the data to
6738 the network before removing the client entry.
6740 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6743 an client is killed from the SILC Network. Updated the protocol
6746 Added new function silc_server_send_notify_killed to the
6747 silcd/packet_send.[ch].
6749 * Added function silc_server_packet_relay_notify to relay notify
6750 packets that are destined directly to a client. In this case
6751 the server does not process the notify packets but merely relays
6752 it to the client. Affected file silcd/packet_send.[ch].
6754 Added also silc_server_packet_process_relay_notify to check
6755 whereto relay the notify. Affected file is
6756 silcd/packet_receive.[ch].
6758 * Implemented the KILL command to the server.
6762 * Added the backup schema desgined last fall to the protocol
6763 specs for everyone to see. The specification is in the
6764 *-spec-xx.txt draft and the packet type definitions for the
6765 backup routers is in *-pp-xx.txt draft. Thusly, added also
6766 new packet type SILC_PACKET_CELL_ROUTERS.
6768 * A big security problem in the implementation discovered. The
6769 signoff of an client did not cause new channel key generation
6770 which it of course should've done. The channel keys must be
6771 always re-generated when client leaves (or signoffs) the channel.
6772 The silc_server_remove_from_channels funtion now handles
6773 the channel key re-generation.
6775 * Added `sender' argument to the silc_server_send_notify_on_channels
6776 to not to send the client provided as argument. Affected file
6777 silcd/packet_send.[ch].
6779 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Implemented OPER and SILCOPER commands into the server and
6784 * Added silc_auth_verify and silc_auth_verify_data to verify
6785 the authentication directly from the authentication payload.
6786 It supports verifying both passphrase and public key based
6787 authentication. Affected file lib/silccore/silcauth.[ch].
6789 * Added `hash' field to the SilcIDListData structure. It is the
6790 hash negotiated in the SKE protocol. Affected file is
6793 * Slight redesigning of the SilcAuthPayload handling routines.
6794 Do not send SilcPKCS but SilcPublicKey as argument.
6796 * Implemented the public key authentication support to the
6797 serverconfig. The public key is loaded from the provided path
6798 and saved as authentication data to void * pointer. Thus,
6799 changed the unsigned char *auth_data to void *auth_data;
6801 * Fixed SHUTDOWN command to send the reply before the server
6802 is shutdown. :) Affected file silcd/command.c.
6804 * Fixed fatal bug in CONNECT command. The hostname was invalid
6805 memory and server crashed. Affected file silcd/command.c.
6807 * Fixed fatal bug in CLOSE command. The server_entry became
6808 invalid but was referenced later in the command. Affected file
6811 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Fixed fatal bug in failure packet handling. Server ignored
6814 the failure and thus crashed when it came.
6818 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6821 that the command may be executed only once in (about) 2 seconds.
6822 The old SILC_CF_LAG flag is same but allows command bursts up
6823 to five before limiting.
6825 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6826 server code. Various commands now includes the CF_LAG_STRICT
6827 flag to disallow any kind of miss-use of the command.
6829 * Fixed the silc_buffer_unformat to not to allocate any data
6830 if the length of the data is zero. It used to allocate the
6831 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6833 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Changed the format of AdminConnection configuration section
6836 in the server. Added username of the admin to the format.
6837 Affected files silcd/serverconfig.[ch].
6839 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6840 to return admin configuration data by host, username and/or
6843 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Implemented WHOWAS command to the server. Added the functions:
6847 silc_server_command_whowas_parse,
6848 silc_server_command_whowas_send_reply,
6849 silc_server_command_whowas_from_client and
6850 silc_server_command_whowas_from_server
6852 * Added <Client ID> argument to the WHOWAS command reply. Updated
6853 the protocol specs accordingly.
6855 * Implemented WHOWAS command and command_reply to the client
6858 Implemented the WHOWAS printing on the user interface.
6860 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Added new argument to the WHOWAS command reply, the real name.
6863 It is an optional argument. Updated the protocol specs.
6865 * Added SilcIDCacheDestructor callback that is registered when
6866 the SilcIDCache is allocated. The callback is called when
6867 an cache entry in the ID Cache expires, or is purged from the
6868 cache. Added into lib/silccore/idcache.[ch].
6870 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6871 to destruct the client entries when the cache entry expires.
6872 Other ID Cache's in server and in the client library ignores
6875 * If the ID Cache entry's `expire' field is zero then the entry
6876 never expires. Added boolean `expire' argument to the
6877 silc_idcache_add function in the lib/silccore/idcache.[ch].
6878 If it is TRUE the default expiry value is used.
6880 * Added silc_server_free_client_data_timeout that is registered
6881 when client disconnects. By default for 5 minutes we preserve
6882 the client entry for history - for WHOWAS command.
6884 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Added support to the server to enforce that commands are not
6887 executed more than once in 2 seconds. If server receives
6888 commands from client more frequently, timeout is registered
6889 to process the commands. Affected file silcd/command.c.
6890 Added new function silc_server_command_process_timeout.
6892 * Changed NICK_NOTIFY handling in client library to check that
6893 if the client's nickname was changed, so there is no need to
6894 resolve anything from the server.
6896 * Removed error printing from the WHOIS and IDENTIFY commands.
6897 If error occurs then it is ignored silently in the client library.
6898 The application, however, may map the received error to
6899 human readable error string. The application currently maps
6900 the NO_SUCH_NICKNAME error to string.
6902 * Made the command status message public to the application. Moved
6903 them from lib/silcclient/command_reply.c to
6904 lib/silcclient/command_reply.h. The application can map the
6905 received command status to the string with the
6906 silc_client_command_status_message function.
6908 * Added check to the server to check that client's ID is same
6909 as the Source ID in the packet the client sent. They must
6912 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added dist-bzip hook to the Makefile.am to make bzip2
6915 compressed distributions.
6917 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Server now enforces the maximum length for the nickname and
6920 the channel as protocol specification dictates. 128 bytes for
6921 nickname and 256 bytes for channel name.
6923 * Moved the WHOIS printing to the application. The client libary
6924 does not print out the WHOIS information anymore, the application
6925 must do it. Renamed silc_client_command_reply_whois_print to
6926 the silc_client_command_reply_whois_save.
6928 The client's idle time is also sent to the application now, and
6929 the idle is shown on screen.
6931 * Added silc_client_command_reply_identify_save to save the
6932 received IDENTIFY entries.
6934 * Do not check for channel private keys in message sending and
6935 reception if the channel does not have the PRIVKEY mode set.
6936 Affected file lib/silclient/client_channel.c.
6938 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6941 just surfaced after chaning the JOIN procedure.
6943 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added silc_client_get_clients_by_list to get client entries
6946 from Client ID list, that is returned for example by JOIN
6947 and USERS command replies. The application should use this
6948 function for example when JOIN command reply is received to
6949 resolve the clients already on the channel (library does not
6950 do that anymore as USERS command reply is not used in the JOIN
6951 procedure anymore). Affected files lib/silcclient/silcapi.h and
6952 lib/silcclient/idlist.c.
6954 * JOIN command reply and USERS command reply returns now SilcBuffer
6955 pointers instead of unsigned char pointers when returning
6956 the client list and mode list.
6958 * Added <Client ID> argument to the JOIN command reply, mainly
6959 for the server to identify for which client the command was
6960 originally sent. Updated protocol specs accordingly.
6962 * Added SilcDlist private_key pointer to the SilcChannelEntry
6963 in the client to support the channel private keys. Affected
6964 file is lib/silcclient/idlist.h.
6966 * Added SilcChannelPrivateKey argument to the function
6967 silc_client_send_channel_message so that application can choose
6968 to use specific private ke if it wants to. If it is not provided,
6969 the normal channel key is used, unless private keys are set.
6970 In this case the first (key that was added first) is used
6971 as the encryption key.
6973 * Implemented the support for channel private key handling.
6974 Implemented the following functions:
6976 silc_client_add_channel_private_key,
6977 silc_client_del_channel_private_keys,
6978 silc_client_del_channel_private_key,
6979 silc_client_list_channel_private_keys and
6980 silc_client_free_channel_private_keys
6982 Affected file lib/silcclient/client_channel.c.
6984 * Added the support for the private keys in the channel message
6985 sending and encryption and in the message reception and
6986 decryption. Affected funtions are
6987 silc_client_send_channel_message and silc_client_channel_message.
6989 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6991 * Added SKE's key verify callback to the client library's
6992 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6994 * Removed the statement that server (or router) must send USERS
6995 command reply when joining to the channel so that the client
6996 knows who are on the channel. Instead, the client list and
6997 client's mode list is now sent in the JOIN command reply to the
6998 client who joined channel. This is better solution.
7000 * Added function silc_server_get_users_on_channel and function
7001 silc_server_save_users_on_channel to the silcd/server.[ch].
7003 * Removed function silc_server_command_send_users from the
7006 * Do not show topic on the client library anymore. The topic is
7007 sent in the command reply notify to the application and the
7008 application must show the topic now.
7010 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7012 * Added client searching by nickname hash into the IDENTIFY and
7013 WHOIS commands in the server as they were clearly missing from
7014 them. Affected file is silcd/command.c.
7016 * Fixed a bug in private message receiving in the client library.
7017 The remote ID was freed and it wasn't supposed, now it is
7020 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Minor fix to the channel payload; allocate the data area, as it
7023 needs to be of specific length.
7025 * If the key agreement port is zero then the operating
7026 system will define the bound port. Affected files are
7027 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7029 * Added new function silc_channel_payload_decrypt into the file
7030 lib/silccore/silcchannel.[ch].
7032 * Moved the channel message etc, check from silc_packet_decrypt
7033 to applications. The library calls now a generic
7034 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7035 when the packet is either normal or special. This was done to
7036 allow more wide range of checking that was not allowed when
7037 the code was in library. Now applications can do virtually any
7038 checks to the packet and return to the library the decision how
7039 the packet should be processed. Affected files are
7040 lib/silccore/silcpacket.[ch].
7042 Added silc_server_packet_decrypt_check to the server and
7043 silc_client_packet_decrypt_check to the client library.
7045 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7046 to send with specified source and destination information.
7048 * Channel message delivery between routers was broken after the
7049 channel key distribution was fixed earlier. The channel key
7050 was used be to distributed to other routers as well which is not
7051 allowed by the protocol. Now this is fixed and channel keys
7052 really are cell specific and the channel message delivery between
7053 routers comply with the protocol specification.
7055 * Fixed various commands in server to check also the global list
7056 for the channel entry and not just the local list. The affected
7057 file silcd/command.c.
7059 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Added assert()s to buffer formatting and unformatting routines
7062 to assert (if --enable-debug) when error occurs. Affected
7063 file: lib/silcutil/silcbuffmt.c.
7065 * Changed to auto-reconnect to check whether the remote host is
7066 router and register the re-connect timeout if it is. It used
7067 to check that whether we are normal server, but router must do
7068 auto-reconnect with another router as well. Affected file
7071 * Removed the [<key len>] option from CMODE command as the cipher
7072 name decides the key length, nowadays. See the defined ciphers
7073 from the protocol specification.
7075 * Added [<hmac>] option to the CMODE command to define the HMAC
7076 for the channel. Added SILC_CMODE_HMAC channel mode.
7078 * Added [<hmac>] option for the JOIN command so that user can
7079 select which HMAC is used to compute the MACs of the channel
7082 * Added Hmac field to the Channel Message Payload. The integrity
7083 of plaintext channel messages are now protected by computing
7084 MAC of the message and attaching the MAC to the payload. The
7085 MAC is encrypted. Now, it is clear that this causes some
7086 overhead to the size of the packet but rationale for this is that
7087 now the receiver can verify whether the channel message decrypted
7088 correctly and also when private keys are set for the channel the
7089 receiver can decrypt the packet with several keys and check from
7090 the MAC which key decrypted the message correctly.
7092 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7093 lib/silccrypt/silccipher.[ch].
7095 * Added silc_hash_len to return the digest length into the
7096 lib/silcrypt/silchash.[ch].
7098 * Rewrote parts of Silc Channel Payload interface in the
7099 lib/silccore/silcchannel.[ch]. The encode function now also
7100 encrypts the packet and parse function decrypts it.
7102 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Fixed a minor formatting bug in the SKE's key material processing.
7105 It actually might have processed the keys wrong way resulting
7108 * Redefined the mandatory HMAC algorithms and added new algorithms.
7109 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7110 and hmac-md5 truncated to 96 bits. The mandatory is now
7111 hmac-sha1-96. Rest are optional (including the one that used
7112 to be mandatory). Rationale for this is that the truncated HMAC
7113 length is sufficient from security point of view and can actually
7114 make the attack against the HMAC harder. Also, the truncated
7115 HMAC causes less overhead to the packets. See the RFC2104 for
7118 * Added new [hmac] configuration section. The SKE used to use
7119 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7120 is of course wrong. The official names that must be proposed in
7121 the SKE are the ones defined in the protocol specification
7122 (hmac-sha1-96 for example). The user can configure any hmac
7123 using any hash function configured in the [hash] section. At
7124 least, the mandatory must be configured.
7126 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7128 * Added HMAC list to the SKE proposal list. It has now both
7129 hash algorithm list and HMAC list. This makes the protocol
7130 incompatible with previous versions. The SKE now seems to work
7131 the way it is supposed to work, for the first time actually.
7133 * Defined plain Hash algorithms to the protocol specification.
7136 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Implemented support for key agreement packets into the server.
7139 Added functions silc_server_key_agreement and
7140 silc_server_send_key_agreement. Other than these functions,
7141 server has nothing to do with this packet.
7143 * Added support for private message key packets into the server.
7144 Added functions silc_server_private_message_key and
7145 silc_server_send_private_message_key.
7149 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7150 called in the protocol's final callback instead in the END
7151 protocol state. This makes a little more sense and in the same
7152 time in client we can use the same protocol routines for normal
7153 key exchange and to key agreement packet handling as well.
7155 * Added to both client's and server's KE protocol context the
7156 SilcSKEKeyMaterial pointer to save the key material. We will
7157 bring the key material to the protocol's final callback by doing
7158 this. The final callback must free the key material.
7160 * Added SKE's packet_send callback into client's KE protocol
7161 context so that the caller can choose what packet sending function
7162 is used. This way we can use different packet sending when
7163 doing normal SKE when doing key agreement packet handling (in
7164 the key agreement packet handling we do not want to encrypt
7167 * Implemented the responder side of the key agreement routines
7168 in the client. The client can now bind to specified port and
7169 accept incoming key negotiation. The key material is passed
7170 to the application after the protocol is over.
7172 * Implemented the processing of incoming Key Agreement packet
7173 in the client. Added function silc_client_key_agreement to
7176 * Implemented the intiator side of the key agreement routines
7177 in the client. The client can now initiate key agreement with
7178 another remote client. The key material is passed to the
7179 application after the protocol is over.
7181 * Created client_keyagr.c to include all the key agreement
7184 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7185 SILC_TASK_CALLBACK except that it is not static.
7187 * Created client_notify.c and moved the Notify packet handling
7188 from the client.[ch] into that file.
7190 * Created client_prvmsg.c and moved all private message and
7191 private message key routines from the client.[ch] into that file.
7193 * Create client_channel.c and moved all channel message and
7194 channel private key routines from the client.[ch] into that file.
7196 * Changed silc_client_get_client_by_id_resolve to resolve with
7197 WHOIS command instead of IDENTIFY command, in the file
7198 lib/silclient/idlist.c.
7200 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Implemented the SKE's responder side to the Client library.
7204 * When FAILURE is received to the protocol do not trust it
7205 blindly. Register a timeout to wait whether the remote closes
7206 the connection as it should do it, only after that process the
7207 actual failure. This was changed to both client and server.
7209 * Added client_internal.h to include some of the structures
7210 there instead of client.h in lib/silcclient/.
7212 * Added function silc_task_unregister_by_callback to unregister
7213 timeouts by the callback function.
7215 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Some "Incomplete WHOIS info" errors has been appearing on the
7218 log files. Took away the entry->userinfo check from WHOIS
7219 reply sending. The entry->userinfo is now " " if client did not
7220 provide one. I thought this was fixed earlier but something
7221 is wrong still. Let's see if the error still appears.
7223 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Fixed a minor bug in the login when the channel key is
7226 re-generated in the server. It used to generate the key in
7227 wrong order and thus caused problems in the channel traffic.
7229 * Fixed a minor bug in channel key distsribution after
7230 KICK command. The key was not sent to the router even though
7233 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Added silc_ske_process_key_material_data as generic routine
7236 to process any key material as the SILC protocol dictates. The
7237 function is used by the actual SKE library but can be used by
7238 applications as well. This relates to the private message keys
7239 and the channel private keys since they must be processed the
7240 same way the normal SILC session keys. The protocol dictates
7241 this. Affected files: lib/silcske/silcske.[ch].
7243 Added also silc_ske_free_key_material to free the
7244 SilcSKEKeyMaterial structure.
7246 * Defined silc_cipher_set_key function to set the key for
7247 cipher without using the object's method function. The affected
7248 files: lib/silccrypt/silccipher.[ch].
7250 * Implemented silc silc_client_add_private_message_key,
7251 silc_client_add_private_message_key_ske,
7252 silc_client_del_private_message_key,
7253 silc_client_list_private_message_keys and
7254 silc_client_free_private_message_keys functions in the
7257 Added functions silc_client_send_private_message_key to send
7258 the Private Message Key payload and silc_client_private_message_key
7259 to handle incoming Private Message Key payload.
7261 * Added Cipher field to the Private Message Key payload to set
7262 the cipher to be used. If ignored, the default cipher defined
7263 in the SILC protocol (aes-256-cbc) is used.
7265 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Removed lib/silcclient/ops.h file.
7269 Redefined parts of the SILC Client Library API. Created new
7270 file silcapi.h that deprecates the ops.h file and defines the
7271 published Client Library API. Defined also private message key
7272 API and channel private key API into the file.
7274 This is the file that the application must include from the
7275 SILC Client Library. Other files need not be included by
7276 the application anymore.
7278 * Added new key_agreement client operation callback and also
7279 defined the Key Agreement library API for the application.
7281 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7283 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7284 is used by clients to request key negotiation between another
7285 client in the SILC network. If the negotiation is started it
7286 is performed using the SKE protocol. The result of the
7287 negotiation, the secret key material, can be used for example
7288 as private message key.
7290 Implemented the Key Agreement payload into the files
7291 lib/silccore/silauth.[ch].
7293 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Redefined ciphers for the SILC protocol. Added some new ciphers
7296 and defined the key lengths for the algorithms. Changed the
7297 code accordingly. The default key length is now 256 bits.
7299 * Fixed SKE key distribution function silc_ske_process_key_material
7300 when the key length is more than 128 bits. The default key
7301 length in SILC is now 256 bits.
7303 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7304 to indicate unsupported algorithm.
7306 * Renamed rijndael.c to aes.c and all functions as well.
7308 * Fixed a long standing channel key setting bug in client library.
7309 Weird that it has never surfaced before.
7311 * Fixed bug in channel deletion. If the entire channel is removed
7312 then it must also delete the references of the channel entry
7313 from the client's channel list as the client's channel entry and
7314 the channel's client entry share same memory.
7316 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7318 * Implemented CONNECT and SHUTDOWN commands in the client.
7320 * Implemented CLOSE command to the client.
7322 * Added the function silc_idlist_find_server_by_name into the
7323 files silcd/idlist.[ch].
7325 Added the function silc_idlist_find_server_by_conn into the
7326 files silcd/idlist.[ch].
7328 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * DIE command was renamed to SHUTDOWN. Updated the both code
7333 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7334 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7336 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7339 * Added function silc_server_create_connection function to create
7340 connection to remote router. My server implementation actually
7341 does not allow router to connect to normal server (it expects
7342 that normal server always initiates the connection to the router)
7343 so the CONNECT command is only good for connecting to another
7346 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7349 or some other client was kicked from the channel.
7351 Implemented the handling of the notify type to both client
7354 Implemented silc_server_send_notify_kicked to send the KICKED
7355 notify. It is used to send it to the server's primary router.
7357 * Implemented the KICK command into server and client.
7359 * Added `query' argument to the silc_idlist_get_client function
7360 to indicate whether to query the client from server or not if
7363 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7364 to indicate that the client is not channel founder.
7368 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Removed the rng context from SilcPacketContext structure and
7371 changed that the packet routine uses the Global RNG API.
7373 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Added support for quit message that client can "leave" on the
7376 channel when it quits the SILC. It is ditributed inside the
7377 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7379 Added silc_server_free_client_data that will take the
7380 signoff message as argument.
7382 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7384 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Updated parts of the protocol specification to keep it up
7389 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7391 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7392 payloads in one packet.
7394 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7395 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7396 use now the new List flag.
7398 * Also deprecated the following packet types: REPLACE_ID,
7399 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7401 * Added list support for Notify packet in server.
7403 * Added silc_server_send_notify_channel_change to send the
7404 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7405 the silc_server_send_replace_id.
7407 * Added silc_server_send_notify_nick_change to send the
7408 NICK_CHANGE notify type. Deprecates the function
7409 silc_server_send_replace_id.
7411 * Added silc_server_send_notify_join to send the JOIN notify type.
7412 Deprecates the function silc_server_send_new_channel_user.
7414 * Added silc_server_send_notify_leave to send LEAVE notify type.
7415 Deprecates the function silc_server_send_remove_channel_user.
7417 * Added silc_server_send_notify_cmode and
7418 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7419 types. Deprecates the silc_server_send_set_mode function.
7421 * Added SERVER_SIGNOFF notify type to indicate that server has
7422 quit. This means that all clients on the channel from that
7423 server will drop. This can be also used when netsplit happens.
7425 Deprecated REMOVE_ID packet type since it is not needed anymore
7428 Added silc_server_send_notify_server_signoff to send the
7429 SERVER_SIGNOFF notify type. Deprecates the function
7430 silc_server_send_remove_id.
7432 Added also silc_server_send_notify_signoff to send the
7433 SIGNOFF notify type.
7435 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7436 SILC protocol from this day on. Changed the protocol
7437 specification as well.
7439 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7440 notify type. It is used between routers to notify about
7441 topic changes on a channel.
7443 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7446 * Partly updated the protocol specification to comply with the
7447 changes now made. It is still though a bit outdated.
7449 * The JOIN notify type now takes one extra argument <Channel ID>.
7450 The packet used to be destined to the channel but now the
7451 JOIN type may be sent as list thus it is impossible to
7452 destine it to any specific channel. By adding this argument
7453 it is again possible.
7455 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Added CREDITS file. The CHANGES and CREDITS file will appear
7458 in the distribution as well.
7460 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7463 types in the server's silcd/packet_receive.c.
7465 * Implemented CMODE and CUMODE to work in router environment.
7467 * Fixed minor encoding and decoding buglet from the
7468 lib/silccore/silcmode.c.
7470 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7473 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7475 * Changed all SilcConfigServer* and silc_config_server* to
7476 SilcServerConfig* and silc_server_config*, respectively.
7479 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Associated the ID (client or server ID) to the Authentication
7482 Payload to avoid any possibility of forging. Updated the
7483 protocol specification and the code accordingly.
7485 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * The RSA key length is now save to the RsaKey context in the
7488 key generation process in lib/silccrypt/rsa.c. The key length
7489 is now used to figure out the maximum size of the block allowed
7490 to be encrypted/signed.
7492 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7493 is equivalent to the silc_mp_mp2bin but does not allocate any
7496 * Changed silc_mp_mp2bin API to take length argument. If it is
7497 non-zero then the buffer is allocated that large. If zero, then
7498 the size is approximated using silc_mp_sizeinbase, which however
7501 * Created Global RNG API which is global RNG that application can
7502 initialize. After initializing, any routine anywhere in the
7503 code (including library) can use RNG without allocating a new
7504 RNG object. This was done to allow this sort of use of the
7505 RNG in code that has no chance to allocate RNG object. All
7506 applications currently allocate this and many routines in the
7507 library use this. Affected file lib/silccrypt/silcrng.[ch].
7509 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7510 it to use the Global RNG API.
7512 * Defined Authentication Payload into protocol specification that
7513 is used during SILC session to authenticate entities. It is
7514 used for example by client to authenticate itself to the server
7515 to obtain server operator privileges.
7517 Implemented this payload into the lib/silccore/silcauth.[ch].
7518 Implemented also routines for public key based authentication
7519 as the new protocol specification dictates.
7521 Moved definitions of different authentication methods from
7522 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7524 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7525 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7526 silc_pkcs_verify_with_hash functions into the file
7527 lib/silccrypt/silcpkcs.[ch].
7529 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * The client entry's userinfo pointer must be always valid.
7532 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7533 will fail since it requires the userinfo. Now, the userinfo
7534 is allocated as "" if actual userinfo does not exist. Actually,
7535 it must exist and it is totally Ok to drop client connections
7536 that does not announce the userinfo. However, we will make
7537 this workaround for now.
7539 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7540 to return the remote port by socket.
7542 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7545 SILC_SERVER_PENDING_EXEC and added an new macro
7546 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7547 data or when error occurs while processing the pending command.
7549 Added new argument `destructor' into silc_server_command_pending
7550 and to the SilcServerCommandPending object. This destructor is
7551 now called after calling the pending callback or if error occurs
7552 immediately. If error occurs the actual pending callback won't
7553 be called at all - only the destructor. The destructor may be
7554 NULL if destructor is not needed.
7556 All this applies for client library code as well. Similar
7557 changes were made there as well for the pending commands.
7559 In the client, the application must now allocate the
7560 SilcClientCommandContext with the silc_client_command_alloc
7563 * Added reference counter to the SilcServerCommandContext. Added
7564 function silc_server_command_alloc and silc_server_command_dup
7567 Same type of functions added to the client library for the same
7570 * Removed the cmd_ident from IDListData away since it is now
7571 global for all connections. It is the command identifier used
7572 in command sending and with pending commands. The affected file
7575 * Added reference counter to the SilcSocketConnection objecet to
7576 indicate the usage count of the object. The object won't be
7577 freed untill the reference counter hits zero. Currently only
7578 server uses this, and client ignores it. The client must be
7579 set to use this too later. The affected files are
7580 lib/silccore/silcsockconn.[ch]. Added also the function
7581 silc_socket_dup to increase the reference counter.
7583 This was mainly added because it is possible that the socket
7584 is removed underneath of pending command or other async
7585 operation. Now it won't be free'd and proper DISCONNECTING
7586 flags, etc. can be set to avoid sending data to connection that
7587 is not valid anymore.
7589 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7590 the connection. After that it sets SILC_SET_DISCONNECTED.
7591 It is, however, possible that the socket data is not still freed.
7592 The silc_server_packet_process now checks that data is not
7593 read or written to connection that is DISCONNECTED. The socket
7594 get's freed when the reference counter hits zero.
7596 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Changed the client operation API: channel_message operation's
7599 `sender' is now the client entry of the sender, not the nickname
7600 and the `channel' is the channel entry, not the channel name.
7602 In the private_message operation the `sender' is now also the
7603 client entry of the sender not the nickname.
7605 Affected file is lib/silcclient/ops.h and all applications
7606 using the client operations.
7608 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Moved the calling of ops->connect() from connect_to_server_final
7611 into receive_new_id functin since that is the point when the
7612 client is actually allowed to send traffic to network. The
7613 affected file is lib/silcclient/client.c.
7615 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7618 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7619 (if needs broadcasting) instead of broadcasting the packets one
7620 by one which would make a burst in the network traffic.
7622 * Added `broadcast' argument to the functions in silcd/server.[ch]
7623 silc_server_create_new_channel[_with_id] to indicate whether
7624 to send New Channel packet to primary router.
7626 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Added new function into the silcd/server.[ch] files:
7629 silc_server_create_new_channel_with_id to create new channel with
7630 already existing Channel ID.
7632 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7633 lib/silccore/silcpacket.h. This packet is used t send list of
7634 Set Mode payloads inside one packet. Server uses this to set
7635 the modes for the channels and clients on those channels, that it
7636 announced to the router when it connected to it. The protocol
7637 specification has been updated accordingly.
7639 * The silc_server_new_channel did not handle the packet coming
7640 from normal server as it normally does not send that. However,
7641 when it announces its channels it does send it. Implemented
7642 the support for that.
7644 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7645 into the file lib/silccore/id.h.
7647 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7649 * Fixed memory leaks in the functions silc_idlist_del_client,
7650 silc_idlist_del_channel and silc_idlist_del_server in the file
7651 silcd/idlist.c. All of those leaked like a sieve.
7653 * Fixed some small memory leaks in the client's function
7654 silc_client_notify_by_server.
7656 * Added functions into silcd/server.c: silc_server_announce_clients,
7657 silc_server_announce_channels and silc_server_announce_server.
7658 These functions are used by normal and router server to announce
7659 to its primary router about clients, channels and servers (when
7660 router) that we own. This is done after we've connected to the
7663 These functions effectively implements the following packet types:
7664 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7665 and SILC_PACKET_NEW_ID_LIST.
7667 * Added new functions into the silcd/packet_receive.[ch]:
7668 silc_server_new_id_list, silc_server_new_channel_list and
7669 silc_server_new_channel_user_list to handle the incoming
7670 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7672 * Added support of changing Channel ID in the function
7673 silc_server_replace_id. If the server that announces a channel
7674 to the router already exists in the router (with same name but
7675 with different Channel ID), router is responsible to send
7676 Replace ID packet to the server and force the server to change
7677 the Channel ID to the one router has.
7679 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7680 client that the Channel ID has been changed by the router. The
7681 normal server sends this to the client. Client must start using
7682 the new Channel ID as the channel's ID.
7684 Implemented handling of this new type into lib/silcclient/client.c
7685 into the function silc_client_notify_by_server.
7687 * Added new function silc_idlist_replace_channel_id into the files
7688 silcd/idlist.[ch] to replace the Channel ID.
7690 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Call silc_server_command_identify_check always when processing
7693 the IDENTIFY command in silcd/command.c
7695 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7698 send keepalive packets. The packet can be sent by clients,
7699 servers and routers.
7701 Added function silc_socket_set_heartbeat into the file
7702 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7703 If not set, the heartbeat is not performed. The actual
7704 heartbeat is implemented in the low level socket connection
7705 library. However, application is responsible of actually
7708 Added silc_server_send_heartbeat to send the actual heartbeat
7709 packet into silcd/packet_send.[ch]. Server now performs
7710 keepalive with all connections.
7712 * Added silc_task_get_first function into lib/silcutil/silctask.c
7713 to return the timeout task with shortest timeout. There was a bug
7714 in task unregistration that caused problems. TODO has been
7715 updated to include that task system must be rewritten.
7717 * The client library will now resolve the client information when
7718 receiving JOIN notify from server for client that we know but
7719 have incomplete information.
7721 * Rewrote parts of silc_server_remove_from_channels and
7722 silc_server_remove_from_one_channel as they did not remove the
7723 channel in some circumstances even though they should've.
7725 * Encryption problem encountered in server:
7727 The LEAVE command used to send the Channel Key packet to the
7728 router immediately after generating it. However, the code
7729 had earlier sent Remove Channel user packet but not immediately,
7730 ie. it was put to queue. The order of packets in the router
7731 was that Channel Key packet was first and Remove Channel User
7732 packet was second, even though they were encrypted in the
7733 reverse order. For this reason, MAC check failed. Now, this
7734 is fixed by not sending the Channel Key packet immediately but
7735 putting it to queue. However, this is more fundamental problem:
7736 packets that are in queue should actually not be encrypted
7737 because packets that are sent immediately gets encrypted
7738 actually with wrong IV (and thus MAC check fails). So, packets
7739 that are in queue should be encrypted when they are sent to
7740 the wire and not when they put to the queue.
7742 However, the problem is that the current system has not been
7743 designed to work that way. Instead, the packet is encrypted
7744 as soon as possible and left to the queue. The queue is then
7745 just purged into wire. There won't be any fixes for this
7746 any time soon. So, the current semantic for packet sending
7749 o If you send packet to remote host and do not force the send
7750 (the packet will be in queue) then all subsequent packets to the
7751 same remote host must also be put to the queue. Only after the
7752 queue has been purged is it safe again to force the packet
7755 o If you send all packets immediately then it safe to send
7756 any of subsequent packets through the queue, however, after
7757 the first packet is put to queue then any subsequent packets
7758 must also be put to the queue.
7760 Follow these rules and everything works fine.
7762 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Added new function silc_server_remove_clients_by_server to
7765 remove all client entries from ID list when the server connection
7766 is lost. In this case it is also important to invalidate all
7767 client entires as they hold the invalid server entry. This
7768 fixes fatal bug when server has lost connection and will reconnect
7771 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Made some sanity checks to silc_server_daemonise like to check
7774 whether the requested user and group actually exists.
7776 * Added sanity check to SKE's silc_ske_responder_finish to check
7777 that the public and private key actually is valid.
7779 * Invalidate the client's nickname when receiving Replace ID
7780 packet and the Client ID is being replaced. This means that the
7781 server will query the nickname if someone needs it (client)
7784 * Sort the ID Cache in client library when the ID Cache data
7785 has changed (needs sorting).
7787 * Do not allow for SILC client to create several connections to
7788 several servers. The client does not support windows right now
7789 and generating multiple connections causes weird behaviour.
7791 Irssi-silc client does support windows and can handle several
7792 connections without problems, see: www.irssi.org and SILC plugin.
7794 * Fixed some places where client was added to the IDList. The
7795 rule of thumb is following (in order to get everything right):
7796 If the client is directly connected local client then the
7797 `connection' argument must be set and `router' argument must be
7798 NULL to silc_idlist_add_client function. If the client is not
7799 directly connected client then the `router' argument must
7800 bet set and the `connection' argument must be NULL to the
7801 silc_idlist_add_client function.
7803 * The funtion silc_server_packet_send_local_channel actually did
7804 not check whether the client was locally connected or not. It
7805 does that now. Fixed a bug related to LEAVE command.
7807 * Fixed Remove Channel User payload parsing bug in server's
7808 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7810 * The server's silc_server_save_channel_key now checks also the
7811 global ID list for the channel as it might not be in the local
7812 list. Fixed a bug related to LEAVE command.
7814 * Is this the end of the [<unknown>] buglet that has been lurking
7815 around for a long time? A little for loop fix in server's
7816 silc_server_command_whois_parse that is used by both IDENTIFY
7817 and WHOIS command. At least, this was a clear bug and a cause
7818 of one type of [<unknown>] buglet.
7820 * WHOIS and IDENTIFY commands call the function
7821 silc_server_command_[whois/identify]_check function even if
7822 we are not router server.
7824 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7826 * Added --with-gmp configuration option. If set the GMP
7827 is always compiled in the SILC source tree. If not set then
7828 it is checked whether the system has the GMP3 installed. If
7829 it has then the GMP won't be compiled (the system's headers
7830 and library is used), if it doesn't have it then the GMP is
7831 compiled in the SILC source tree.
7833 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Changed RSA private exponent generation to what PKCS #1
7836 suggests. We try to find the smallest possible d by doing
7837 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7838 not security fix but optimization.
7840 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7842 * Added new config entry [Identity] to fork the server and run
7843 it as specific user and group. A patch from Bostik.
7845 * Imported Dotconf configuration library into lib/dotconf.
7846 This will be used to create the SILC configuration files later.
7847 It will appear in the distsribution after this commit.
7849 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * A big code auditing weekend happening. Auditing code for
7852 obvious mistakes, bugs and errors. Also, removing any code
7855 Removed files for being obsolete:
7857 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7858 inline in the file lib/silcutil/silcbuffer.h)
7860 o lib/silcutil/silcbufutil.c (the header has inline versions)
7862 Changed code to fix possible error conditions:
7864 o The buffer formatting routines now check that the destination
7865 buffer really has enough space to add the data. This applies for
7866 both buffer formatting and unformatting
7867 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7868 unformatting was changed to accomodate following rules:
7869 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7870 sent to the function while XXX_*STRING will not allocate or copy
7871 the data into the buffer. Instead it sets the pointer from the
7872 buffer into the pointer sent as argument (XXX_*STRING used to
7873 require that the pointer must be allocated already). This change
7874 makes this whole thing a bit more consistent and more optimized
7875 (note that the data returned in the unformatting with XXX_*STRING
7876 must not be freed now). The routines return now -1 on error.
7878 o Tried to find all code that use buffer_format and buffer_unformat
7879 and added return value checking to prevent formatting and
7880 especially unformatting errors and possible subsequent fatal
7883 o Changed ske->x and ske->KEY to mallocated pointers in
7884 lib/silcske/silcske.h. Fixed possible data and memory leak.
7886 o Added return value checking to all *_parse* functions. Fixed
7887 many memory leaks as well.
7889 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7890 so that buffer overflows would not happen. All code now also
7891 checks the return value as it can fail.
7893 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7895 * Added reconnection support to server if the normal server looses
7896 its connection to the router (for example if router is rebooted).
7897 The server performs normal reconnection strategy implemented
7898 to the server. Affected file silcd/server.c.
7900 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7902 * Added new packet type SILC_PACKET_SET_MODE that is used to
7903 distribute the information about changed modes (for clients,
7904 channels and clients channel modes) to all routers in the
7905 network. Updated the protocol specification accordingly.
7907 Added functions into silcd/packet_send.c and
7908 silcd/packet_receive.c: silc_server_send_set_mode,
7909 silc_server_set_mode.
7911 Added new files silcmode.[ch] into lib/silccore that implements
7912 the encoding and decoding of Set Mode Payload. Added new type
7913 SilcSetModePayload. Moved the definitions of different modes
7914 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7916 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7918 * Oops, a little mistake in server's connection authentication
7919 protocol. The protocol is not ended with FAILURE but with
7920 SUCCESS if the authentication is Ok. :) Affected file is
7923 * Implemented NICK_CHANGE notify handling in server in the file
7924 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7925 the local clients on the channel. After the changing nickname
7926 in router environment snhould work and the [<unknown>] nickname
7927 should appear no more.
7929 The silc_server_replace_id function that receives the Replace ID
7930 payload now sends the NICK_CHANGE notify type also in the file
7931 silcd/packet_receive.c
7933 * Changed WHOIS and IDENTIFY command to support the maximum amount
7934 of arguments defined in protocol specs (3328 arguments). This
7935 fixed a bug that caused problems when there were more than three
7938 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7940 * Added extra parameter, command identifier, to the
7941 silc_client_send_command so that explicit command identifier
7944 Changed that ID list routines uses specific command identifier
7945 when sending WHOIS/IDENTIFY requests to the server so that they
7946 can be identified when the reply comes back.
7948 Affected files lib/silcclient/command.[ch],
7949 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7951 * Added `sender' argument to silc_server_packet_send_to_channel
7952 to indicaet the sender who originally sent the packet to us
7953 that we are now re-sending. Ignored if NULL. Affected file
7954 silcd/packet_send.[ch].
7956 * Added some server statistics support in silcd/server_internal.h
7957 SilcServerStatistics structure and around the server code. Also
7958 send some nice statistics information when client is connecting
7961 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Fixed channel ID decoding in server's JOIN command reply in
7964 silcd/command_reply.c
7966 * Fixed braodcasting of replace ID payload to not to send it if
7967 we are standalone server in silcd/packet_receive.c.
7969 * Fixed all channel message sending routines to not to send
7970 packets to clients that has router set, since they are routed
7971 separately in the same function earlier. Affects file
7972 silcd/packet_send.c and all channel packet sending functions.
7974 * In USERS reply, res_argv[i] are not allocated, the table
7975 is allocated. Thus changed that free the table, not its
7978 * In server's whois_check and identify_check if the client is
7979 locally connected do not send any WHOIS commands - they are not
7982 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7984 * Fixed some minor bugs in client when sending WHOIS command. The
7985 arguments was in wrong order.
7987 * Removed statis function add_to_channel from server in
7988 silcd/command.c that was previously used with the joining but
7991 * Tested USERS command in router environment successfully with two
7992 routers, two servers and two clients.
7994 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * Reorganized the USERS command and command reply in client library
7997 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7998 When the command is given by user we register a pending command
7999 callback that will reprocess the command after the reply has been
8000 received from the server. When reprocessing the packet we then
8001 display the information. Thus, the USERS information is displayed
8002 now in the command callback instead of in the command reply
8003 callback. The processing of the command is same as previously
8004 when server has sent the command reply in the JOINing process.
8006 * Added to USERS command in silcd/command_reply.c to join the client,
8007 we didn't use to know about, to the channel after we've created
8008 a client entry for it. Also, for clienet we did know already still
8009 check whether it is on the channel or not and add it if not.
8011 * Removed silc_server_command_join_notify as the function and its
8014 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8016 * Changed the client's pending command handling to the same as the
8017 server's pending command handling. It is also now possible to
8018 execute command reply functions from other command reply
8019 function as the function callbacks for commands and command
8020 replies are one and same. The pending commands are not static
8021 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8022 in client connection context. Thus, pending commands are server
8023 connection specific as it is convenient.
8025 Changed the function silc_client_command_pending and
8026 silc_client_command_pending_del and added new function
8027 silc_client_command_pending_check. Removed the
8028 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8031 * Added cmd_ident, current command identifier, to the client
8032 connection context in lib/silcclient/client.h to keep track on
8033 command identifiers used in command sending. Client's command reply
8034 function handling now supports the mandatory command identifiers.
8036 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8037 funtions in client to fully support pending command callbacks.
8039 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8040 as one of the arguments to the application in the command reply
8043 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8044 before first releasing SILC but came back. Now it is removed again
8045 and should come back nomore. The FORWARDED flag was used only
8046 by the JOINing procedure by forwarding the command packet to router.
8047 Now, the JOINing procedure has been changed to more generic (due
8048 to various router environment issues) and FORWARDED is not needed
8049 anymore for anything. The protocol specification is yet to be
8052 Now, removed silc_server_packet_forward from server and the flag
8053 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8055 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8057 * Renamed NAMES command to USERS command. The NAMES was named that
8058 due to historical reasons. Now it is renamed. Also, rewrote
8059 parts of the USERS command. The nickname list is not sent anymore
8060 by the server. Only Client ID and mode lists are sent in the USERS
8061 command. Changed this also to the protocol specification.
8063 The client now resolves the names and stuff after it receives
8064 the USERS list from the server when joining to the channel.
8066 * WHOIS and IDENTIFY commands has been changed to support multiple
8067 Client ID's per command. One can now search for multiple users
8068 in the network by sending only one WHOIS or IDENTIFY command.
8069 Changed the code and the protocol specifications.
8071 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8072 uses silc_server_command_whois_parse to parse the request. */
8074 * If normal server, do not parse the WHOIS and IDENTIFY requests
8075 before sending it to the router. Saves some time.
8077 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8079 * Fixed JOIN command on client library. Wrong number of arguments
8080 used to crash the client.
8082 * Added silc_server_channel_has_global function to check whether
8083 channel has global users or not.
8085 * Added silc_server_channel_has_local function to check whether channel
8086 has locally connected clients on the channel.
8088 * The silc_server_remove_from_one_channel now checks whether the
8089 channel has global users or not after given client was removed from
8090 the channel. It also checks whether the channel has local clients
8091 on the channel anymore. If it does not have then the channel entry
8092 is removed as it is not needed anymore.
8094 * The silc_server_notify now checks on JOIN notify whether the joining
8095 client is one of locally connected or global. If it is global then
8096 the channel has now global users on the channel and that is marked
8097 to the channel entry. Also, it now saves the global client to
8098 global list who is joining and JOINs it to the channel. This is
8099 for normal server, that is.
8101 Changed silc_server_send_notify_on_channel,
8102 silc_server_packet_relay_to_channel and
8103 silc_server_packet_send_to_channel check if we are normal server
8104 and client has router set (ie. global client) do not send the
8105 message to that client, as it is already routed to our router.
8107 * Implemented LEAVE notify type handling in silc_server_notify
8110 * Tested LEAVE command in router environment successfully. Tested
8111 with two routers, two servers and two clients.
8115 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8117 * Implemented SIGNOFF notify type handling in silc_server_notify
8120 * silc_server_remove_id now removes the client entry from all channels
8121 it has joined and thusly sends SIGNOFF notify type.
8123 * Rewrote the NAMES list generation in server by removing two excess
8124 loops. The lists are created now inside one loop.
8126 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8128 * silc_server_remove_channel_user checks now also global list
8129 for channel and client.
8131 * silc_server_new_channel_user checks now both local and global
8132 list for channel and client. Fixed a bug in client id decoding.
8133 Used to decode wrong buffer.
8135 * silc_server_channel_message checks now both local and global
8136 list for channel entry.
8138 * Tested channel joining (hence JOIN) in router environment
8139 successfully. Tested with two routers, two servers and two
8142 * Tested channel message sending in router environment successfully.
8144 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8146 * Added silc_server_save_channel_key into server.[ch] to save the
8147 received channel key in Channel Key payload processing. It is
8148 also used in JOIN command reply handling.
8150 Equivalent function silc_client_save_channel_key added into
8151 client.[ch] into client library.
8153 * Changed JOIN command reply to send information whether the channel
8154 was created or not (is existing already) and the channel key
8155 payload. Changed protocol specs accordingly.
8157 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8158 the request was sent by ID and not by nickname. Crashed on
8161 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8164 now correctly save the received data.
8166 * silc_server_free_sock_user_data now notifies routers in the
8167 network about entities leaving the network.
8169 At the same time implemented functions silc_server_remove_id
8170 and silc_server_send_remove_id to receive and send REMOVE_ID
8171 packets. The packet is used to notify routers in the network
8172 about leaving entities. The ID removed will become invalid in
8175 * Added function silc_idlist_del_server into server. Removes and
8176 free's server entry from ID list.
8178 * silc_server_private_message function now checks, if we are router,
8179 that the destination ID really is valid ID, naturally.
8181 * In router when NEW_ID packet is received (for new client) the
8182 hash of the Client ID is saved in the ID Cache but the
8183 client->nickname is set to NULL, instead of putting the hash
8186 IDENTIFY command now also checks that client->nickname must be
8187 valid. If it is not if will request the data from the server who
8188 owns the client. Added new function
8189 silc_server_command_identify_check.
8191 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8192 to set the command to already allocated Command Payload.
8194 * Tested private message sending in router environment with two
8195 routers, two servers and two clients. Fixed minor bugs and now
8198 * Fixed segfault from client's NAMES command. Used to crash if
8201 * Forwarded packets must not be routed even if it is not destined
8202 to the receiver. Changed server code comply with this.
8204 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Added `require_reverse_mapping' boolean value to ServerParams
8207 structure. If TRUE (not default) the server will require that
8208 the connecting host has fully qualified domain name.
8210 If the reverse mapping is not required and hostname could not be
8211 found the IP address is used as hostname.
8213 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8215 * Implemented version string checking to both client and server.
8216 The check is incomplete currently due to the abnormal version
8217 strings used in development version of SILC.
8219 * Changed all command functions in server to use the new
8222 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8224 * Changed char *data to unsigned char *data in ID Cache system to
8225 support binary data as ID Cache data. Changed code to support
8226 binary data in lib/silccore/idcache.c.
8228 * Renamed silc_server_packet_relay_command_reply to
8229 silc_server_command_reply as it is normal packet receiving
8230 function. Rewrote the function to accept command replys for
8231 servers and not only for clients.
8233 * Mark remote router always as registered server if we are connecting
8234 to it. Otherwise, commands sent by the router to us are ignored.
8236 * All ID List find routines now returns the ID Cache Entry pointer
8237 as well if requested.
8239 * WHOIS command works now in router environment, tested with two
8240 routers, two servers and two clients.
8242 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8243 in router environment (as it is almost equivalent to WHOIS) but
8244 hasn't been tested thoroughly. Added new functions:
8246 silc_server_command_identify_parse
8247 silc_server_command_identify_send_reply
8248 silc_server_command_identify_from_client
8249 silc_server_command_identify_from_server
8251 * Disabled route cache adding because adding two different ID's with
8252 same IP replaces the old cache entry thus giving wrong route.
8253 The entry->router->connection is always the fastest route anyway
8254 so route cache may not be needed. Of course, new routes maybe
8255 established after receiving the ID when the entry->router->connection
8256 might not be anymore the most optimal.
8258 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8260 * Add route cache for received ID for fast routing.
8262 * Added silc_server_packet_route to route received packet on router
8263 that is not destined to us.
8265 * Renamed silc_server_get_route to silc_server_route_get.
8267 * Added id_string and id_string_len fields into SilcServer to
8268 include encoded ServerID for fast comparing without excess
8269 encoding of the ID's.
8271 * Cleaned up WHOIS command on server side. Added following static
8274 silc_server_command_whois_parse
8275 silc_server_command_whois_check
8276 silc_server_command_whois_send_reply
8277 silc_server_command_whois_from_client
8278 silc_server_command_whois_from_server
8280 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8281 arguments in command replies. All command functions should be
8282 updated to use this macro.
8284 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8286 * Minor typo fixes on command reply handling on server.
8288 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8290 * Added silc_server_command_add_to_channel internal routine to add
8291 the client to the channel after router has created the channel and
8292 sent command reply to the server.
8294 * Added generic silc_server_send_command to send any command from
8297 * Use static buffer with ID rendering instead of duplicating data.
8299 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8301 * Fixed a channel user mode bug when joining to a channel server gave
8302 everybody channel founder rights, oops.
8304 * We mark ourselves as the router of the incoming server connection
8305 if we are router ourselves. This way we can check in some packet
8306 sending functions whether it is locally connected server. For
8307 incoming router connections we put NULL.
8309 * For router sending packets locally means now always sending the
8310 packet cell wide; to local clients and local servers. For normal
8311 server sending packet locally means sending it to only local
8314 * Fixed the JOIN command to really work in router environment. If the
8315 channel is created it is always created by the router. Router is
8316 also responsible of making the initial joining to the channel,
8317 sending JOIN notify to the sending server and distributing
8318 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8319 does not exist server doesn't do anything else but forward the
8320 command to the router which performs everything.
8322 * Added silc_server_send_channel_key function to send the Channel Key
8325 * Added silc_server_create_channel_key to create new channel key. The
8326 channel key is now re-generated everytime someone joins or leaves
8327 a channel, as protocol dictates. Note: channel->key_len is the
8330 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8333 packet_receive.[ch] to separate packet sending and receiving
8334 routines. The server.[ch] now includes everything else including
8335 actual packet processing (writing and reading data) and other
8338 Renamed silc_server_private_message_send_internal to
8339 silc_server_send_private_message. The routine is still though
8340 used only to relay private messages as server does not send
8341 private messages itself.
8343 Renamed silc_server_new_channel to silc_server_create_new_channel
8344 and added new function sicl_server_new_channel that handles the
8345 incoming New Channel packet. Added also new sending function
8346 silc_server_send_new_channel to send New Channel Payload.
8348 * Added new function silc_server_notify to process incoming notify
8349 packet to the server/router. Server may then relay the notify
8350 to clients if needed.
8352 * Added new function silc_server_new_channel_user to process incoming
8353 New Channel User packet. Router will redistribute the packet and
8354 send JOIN notify to its local clients and locally connected servers
8355 if needed. Normal server will send JOIN notify to its local client
8356 on same channel when received this packet. Added also corresponding
8357 sending function silc_server_send_new_channel_user to sent the
8360 * Added boolean route argument to send_notif_to_channel and
8361 packet_send_to_channel functions to attempt to route the packet
8362 if it is TRUE and send only locally if it is FALSE.
8364 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * silc_server_replace_id now broadcasts the received replace ID
8367 packet if it is not broadcast packet already. The router must
8368 broadcast to inform other routers about changed ID.
8370 * Added backpointer to server's router into SilcServer context in
8371 silcd/server_internal.h.
8373 * Fixed silc_server_packet_broadcast to send correct broadcast
8376 * The channel key is now distributed to the local client as soon
8377 as it is received from the router (in router environment) so that
8378 no other packet may be sent for the channel until client has
8381 * silc_server_remove_channel_user now broadcasts the received
8382 Remove Channel User packet if it is not broadcast packet already.
8383 The router must broadcast to inform other routers about removed
8386 * Added users field into SilcPacketContext that is a reference count
8387 of the context. One can increase the reference count by calling
8388 silc_packet_context_dup which is now changed to just increase the
8389 reference count instead of duplicating the data. The reference
8390 count is decresed by calling silc_packet_context_free that will
8391 free the data after the reference count hits zero.
8393 For now on the packet context and everything allocated into it
8394 (including the raw packet from network) must be freed by calling
8395 the new silc_packet_context_free function. Added also new function
8396 silc_packet_context_alloc that must be used now to allocate the
8397 context. This also means that if a routine is asynchronous from
8398 silc_[client/server]_packet_parse_type the packet context must
8399 be duplicated by calling silc_packet_context_dup. Otherwise it
8400 gets free'd after silc_[client/server]_packet_parse_type returns.
8401 Also, one must remember that if packet is duplicated then its
8402 reference count must be decresed by calling the free function as
8403 many times as it was duplicated.
8405 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8406 from both client and server.
8408 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8410 * Made joining to a channel working in router environment.
8412 * Cleaned up JOIN command on server side and create function
8413 silc_server_command_join_channel internal routine to make the
8416 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8418 * Changed silc_command_pending list to SilcDList. Also, added
8419 `ident' field to SilcServerCommandPending structure to identify
8420 the reply and to call correct callback.
8422 Added silc_server_command_pending_check function to replace the
8423 corresnponding macro. The silc_command_pending list is not
8426 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8427 to set identifier to previously allocated Command Payload. It
8428 is used to set identifier for command when resending Command
8431 * Added silc_command_payload_encode_payload to encode Command
8432 Payload buffer from SilcCommandPayload structure.
8434 * Added silc_argument_payload_encode_payload to encode Argument
8435 payload buffer from SilcArgumentPayload structure.
8437 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8439 * Changed WHOIS command to support router connection on server side.
8440 The whois request is always sent to router unless the server is
8441 standalone server. After server has received the reply from the
8442 router will it send the reply to the client.
8444 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8445 broadcast received broadcast packet. The function is used only
8446 by router. The broadcast packet is always sent to the router's
8449 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8450 render given ID to printable string, for log files for example.
8452 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Made basic router to router connections working. At least they
8455 can now connect to each other but nothing really works the way
8456 they are supposed - yet.
8458 * Added new initiator token to RouterConnection configuration
8459 file in silcd/serverconfig.[ch]. It is used to tell whether we
8460 are the initiator to the remote router or whether we'll expect
8461 the other end to connect.
8463 * Moved registering of listener task to silc_server_init, hence
8464 the server starts listenning as soon as it is run, even if it
8465 does not have connections to other routers. Let's see how well
8468 * Changed default connection retry timeouts for more suitable in
8471 * Removed cipher and such arguments from silc_idlist_add_client
8472 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8473 Added new function silc_idlist_add_data to add the keys and stuff
8476 * Added SilcIDListData structure and added it to SilcClientEntry
8477 and SilcServerEntry as their first field in the structure. This
8478 way we can explicitly cast the ID entries to the SilcIDListData
8479 structure and get common data for the entries. In past, we had
8480 to first check what type of connection it is and then cast it to
8481 correct ID entry type. Now, we can directly cast the opaque
8482 pointer to the SilcIDListData (no matter what ID entry it actually
8483 is) and get the data needed.
8485 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8487 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8488 in some circumstances even if threre were timeout tasks, though not
8489 IO tasks, but tasks anyway. Now fixed.
8491 * Defined SilcServerConnection structure to hold connection specific
8492 stuff about directly connected servers and routers. The definition
8493 is currently in silcd/server_internal.h. I thought about having
8494 a bit more important role fro this struct but for now it is used
8495 only when connecting to other server (or router actually).
8497 * Added connecting retry support in server when connecting to
8498 router(s). The retry feature implement exponential backoff
8499 algorithm. Also, added SilcServerParams structure to hold default
8500 parameters for server. For now, it include these retry settings
8501 and are hard coded. After server is moded to be as Silc Server
8502 Library this structure will be more important.
8504 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Changed client librarys channel->clients table to SilcList and
8507 changed code accordingly.
8509 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8511 * Changed client's channel table to SilcList and changed code
8512 accordingly. Also changed SilcChannelClientEntry to include back-
8513 pointer to the channel so that client entry can use that structure
8514 as list as well and we have fast cross-reference to the channel.
8515 This change dramatically decreased the complexity of channel
8516 handling with client entry and vice versa (removed one extra
8517 loop when searching for channel entry from many functions).
8519 * Changed server->sim from table to SilcDList and changed code
8522 * NAMES command can now be used from user interface. It will show
8523 the user list on the channel, neatly.
8525 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8526 Code now saves realname of the user if it becomes available.
8528 * Renamed configure.in to configure.in.pre and made ./prepare
8529 script to automatically add correct version string to
8530 configure.in which it creates from configure.in.pre.
8532 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8534 * NAMES command reply now shows users mode with the nickname when
8537 * Moved silc_client_ch[u]mode[_char] functions from
8538 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8539 place sucks, they are utility functions and should be in some
8542 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8544 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8547 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8551 * Added TRQ (efficient deque and list library) into lib/trq. This is
8552 a very good list library that is currently used in the SILC. Defined
8553 SilcList API over the library because I didn't like the API very
8554 much. See lib/trq/silclist.h for the API and examples of how to
8555 use the API. Fixed various places in the code to use the new
8556 SilcList API. The SilcList is meant for lists that has a structure
8557 already defined as a list. It is not suitable to add just some
8558 context to the list (in TRQ, the context is the list actually).
8560 So, I defined SilcDList that can be used for the purpose where
8561 predefined list structure does not exit. This can be used as
8562 such list. Now some context just can be added to the SilcDList.
8563 Currently this list is not used in the SILC just yet, though there
8564 are a lot places where this can replace dynamically allocated
8565 tables and I will fix these places, later, to use SilcDList.
8566 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8567 and use TRQ internally).
8569 Also fixed some annoying warning messages that the original TRQ
8570 code generated. Also minor changes to TRQ's Makefile.in.
8572 * Added support for querying by Client ID to both WHOIS and
8573 IDENTIFY commands into server, as required by the protocol.
8575 * Removed method function pointers from SilcBuffer structure. They
8576 weren't used to anything and just increased the context size for
8577 no good reason. This change also made silc_buffer_alloc and
8578 silc_buffer_free functions inline functions.
8580 * Disabled command flooding detection support until it's fixed so
8581 that it accepts commands in but does not execute them more than once
8584 * Added silc_net_localhost(), to return local hostname, into
8585 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8586 that must be initialized before calling silc_client_init.
8588 * Added new function: silc_server_send_notify_on_channels to send
8589 notify messages to all channels client has joined. It is assured
8590 that the message is sent only once per client.
8592 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8593 lib/silcutil/silcutil.[ch] as silc_format function. The new
8594 function is generic and is used by server as well, not only by
8595 the logging routines.
8597 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8598 the provided version string was not acceptable. Added new function:
8599 silc_ske_check_version into lib/silcske/silcske.h. The function
8600 must be implemented by the application (client or server) and it
8601 does not reside in the SKE library. The function checks the version
8602 string remote end sent.
8604 * Added back pointers (to opaque context and to SilcSocketConnection)
8605 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8607 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8608 duplicate packet context structure.
8610 * Changed `notify' client operation to send same arguments as client
8611 receives from server except for ID's. ID's are mapped to correct
8612 ID entry and that is returned. Also, if channel entry is not sent
8613 by server but the notify is for channel the channel entry is sent
8614 to application (otherwise application doesn't know that it is for
8615 channel (library gets it from packet's Destination ID)).
8617 * Added silc_client_remove_from_channels into client library to
8618 remove a client from all channels it has joined to. Used when
8619 received SIGNOFF notify from server. Added also new function
8620 silc_client_replace_from_channels to replace old ID entry with
8621 new ID entry on all channels. Used when received NICK_CHANGE
8624 * Fixed ID Cache list handling in silc_idlist_get_client in
8625 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8626 to get (or query) client by ID.
8628 * Updated TODO list.
8630 * Added connection authentication status message defined by the
8631 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8632 support for these into the code in client and server side.
8634 * Added generic function silc_client_send_command to send any command
8635 with variable argument list. Application should use this function
8636 to send commands if the command functions provided by the library
8637 does not suite for the application's user interface needs.
8639 * Added new `failure' client operation. Application is notified about
8640 received failure packet if client is executing a protocol. In this
8641 case the protocol's execution has failed.
8643 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8644 is required by the protocol.
8646 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8647 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8650 * Added status flag to SilcSKE object to indicate realtime status
8651 of the SKE protocol.
8653 * Application receives now exactly same command reply arguments as
8654 the library receives from server. However, if ID is received the
8655 corresponding ID entry is returned to the application (eg. Client
8656 ID is mapped to correct SilcClientEntry entry and that is returned).
8657 Changed command_reply client operation due to this change.
8659 * Changed all ID's in commands and in command replys as ID Payloads.
8660 Change affected both client and server side codes.
8662 All ID's sent in SILC network (with execption of ID's in SILC
8663 Packet header) are sent in ID Payload to support variable length
8666 * Server now notifies nick changes and notifies all clients on
8667 the channels about the new nickname (about the new Client ID,
8670 * Implemented CMODE command to change channel modes. Supports all
8671 channel modes defined by the protocol specs except ban and invite
8672 lists. (Also, private channel key mode is supported but support for
8673 setting private channel key in client is missing, thus, this mode
8674 has no effect on client side (except that server requires that the
8675 client uses private channel key and normal channel traffic does not
8678 Also, invite mode works per se, but INVITE command does not work
8679 yet correctly, so you can set channel as invite only channel but
8680 inviting clients to the channel does not work (it is yet to be
8681 thought what's the best way to do it).
8683 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8684 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8685 Implemented CUMODE command to change user's mode on the channel.
8686 Supports all modes defined by the protocol specs.
8688 * Added NAMES command reply to return users modes on the channel.
8690 * Removed unnecessary and slow ciphers from lib/silccrypt.
8692 * Set SO_KEEPALIVE option to connection sockets by default.
8694 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8696 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8697 redefined the Notify Payload into protocol specs.
8699 * Added silc_id_payload_parse_id to get ID directly from raw
8702 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8704 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8705 accept searching by Client ID as well.
8707 * Added support for LEAVE and SIGNOFF notify types in client library.
8709 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8710 to parse ID Payload from raw data.
8712 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8714 * Added flags parameter into silc_ske_assemble_security_properties
8715 function in lib/silcske/silcske.[ch].
8717 * Changed notify client operation to fit better for notify messages
8718 sent by server. The notify payload received from server is now
8719 passed to the application (after parsing it to SilcNotifyPayload).
8720 It is application's responsibility to retrieve the arguments
8721 from the payload and show the message the way it wants. The message
8722 sent by server is implementation specific.
8724 * Changed public keys to comply with the protocol specification.
8725 Old public keys are not supported anymore and are not compatible.
8727 * Removed nickname from Channel Payload as the latest draft removed
8728 it. The client must resolve the nickname from the NAMES command
8729 reply received when it joined the channel.
8731 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8733 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8735 * Fixed some errors in protocol specification drafts.
8737 * Created lib/silccore/silcnotify.c to implement Notify Payload
8738 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8739 generic payloads described by protocol specifications. The file
8740 includes implementations for ID Payload and Argument Payload.
8742 * Changed Command Payload implementation to use the new Argument
8743 Payload. Changed command_xxxx_payload to command_payload_xxxx
8744 to comply with SILC coding conventions.
8746 * Added suppport for Argument Payload handling in Notify Payload
8747 implementation as protocol requires it. Added the new support
8748 into server and client lib as well.
8750 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8752 * Added support for multiple nicknames on same channel. [n] is
8753 added locally to the nickname if there are more than one same
8754 nicknames on the channel.
8756 * Server now sends all nicknames that matched WHOIS request.
8757 Client also shows the list received from server.
8759 * Added TOPIC command to client side. User can now set and show
8760 current topic on channel.
8762 * Added MOTD command to client and server. Also, server sends the
8763 motd when client connects to the server.
8765 * Changed version strings to comply ISO 8601.
8767 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8769 * Fixed protocol error handling in client library. It should now
8770 cope even if the SKE fails for some reason.
8772 * Made new protocol specification drafts for submitting to IETF.
8774 * Implemented TOPIC command to server in silcd/command.c.
8776 * Added two new notify types into lib/silccore/silcnotify.h:
8777 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8778 notify nickname change and topic setting/change on a channel.
8780 * API change of command_reply operation in client library. The
8781 application gets now the status type received from server as well.
8783 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8785 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8787 * Cras fixed and optimized the packet handling even further and
8788 it should work now. Minor change to the prototype of function
8789 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8791 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8793 * Added new function into lib/silcutil/silcschedule.[ch]:
8794 silc_schedule_with_fd to select() a specified fd. The function
8795 returns after timeout expires or data arrives or goes. The
8796 function is used by packet routines to wait that all data is
8797 received from network.
8799 * Fixed data reading from network in lib/silccore/silcpacket.c.
8800 The code now assures that all data is read from the fd and then
8801 continues packet processing. This was a bug fix since the code
8802 used to drop some data in some circumstances.
8804 * Added new function into lib/silcclient/client.[ch]:
8805 silc_client_start_key_exchange to start key exchange after
8806 connection has been established to server. The code internally
8807 now uses this funtion but its main purpose was to provide it
8808 for applications that perform their own connecting. After
8809 application has created a connection it merely calls this
8810 function to start the key exchange between client and server.
8811 The library takes care of everything else after that.
8813 Updated also lib/silcclient/README to explain the usage of
8816 * Do not send to application information that connection has
8817 been established. Application gets notified it by connect
8820 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8822 * Applied cras's patch to add silc_schedule_one function. The
8823 function runs scheduler once and returns.
8825 * Fixed the scheduler after cras messed it up. The timeout
8826 handling works now as it's supposed to work.
8828 * Added into lib/silccore/ silcnotify.h to include notify
8829 message types support. Changed silc_server_send_notify*
8830 functions, in server.[ch], to support those new notify types.
8831 Added the support for the notify types into client library,
8832 as well. Added new notify client operation into ops.h in
8835 * Changed silc_server_packet_send_to_channel to send normal
8836 packets instead of just channel message packets. The function
8837 is now used to send the notify packets to channels. It is not
8838 used to send channel message packets anymore, as server never
8841 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8842 va_arg()s as it seems to require it nowadays. I guess, if SILC
8843 is compiled with older va_arg() the new code should work anyway.
8845 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8847 * Splitted core library. Core library (lib/silccore) includes
8848 now only SILC protocol specific core (and common) components.
8849 Created new utility library (lib/silcutil) that includes more
8850 generic purpose stuff. The stuff for util library was taken
8851 from the old core library. This was minor and easy split.
8853 * Created SILC Client Library (lib/silcclient) that includes
8854 implementation of the SILC client without user interface. This
8855 was major move from silc/ directory. The code has been changed
8856 so that it is transparent towards the user interface. The
8857 silc/ directory includes now the same user interface as before
8858 and it uses the new client library. Read lib/silcclient/README.
8859 Basicly, the client library performs everything else related
8860 to SILC except user interface handling. Also, configuration
8861 files are considered to be part of user interface and library
8862 does not handle them.
8864 This change also changed a lot of structures, function naming etc.
8865 Most important change was that SilcClientWindow object was
8866 renamed to SilcClientConnection in the client library. Created
8867 also new file lib/silcclient/ops.h. Also added new files
8868 silc/local_command.[ch] and silc/client_ops.[ch].
8870 All these changes were made to make it easier for user interface
8871 designers to create what ever user interface for the SILC client
8874 It is also expected that the server will be moved to lib
8875 directory as well and SILC Server Library will be created;
8876 sometimes in the future.
8878 * Removed Local commands from lib/silccore/silccommand.h as
8879 they are application specific and new client library does not
8880 handle any of those anymore.
8882 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8883 old client implementation in silc/.
8885 * Added support for callback functions in SILC_LOG_* macros.
8886 Application can now set its own callbacks that will be called
8887 instead of using the default functions that will always print
8888 the debug messages to stderr (or stdout). Also, debugging can
8889 now be disabled by setting silc_debug to FALSE and re-enabled by
8890 setting it to TRUE. Note, that logging will still work even
8891 if debugging is disabled.
8893 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8894 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8895 silc_log_reset_debug_callbacks.
8897 * To enable debugging in silc client one must give now -d
8898 option on command line.
8900 * Changed silc_schedule_init to automatically allocate task queues
8901 if they are not allocated before calling it.
8903 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8905 * Added GMP 3.1 into math library.
8907 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8909 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8910 a channel in SILC network. The packet is used by servers and
8911 routers to notify other routers that user has left a channel.
8912 This little feature was missing until now. Added the feature
8913 to protocol specification as well.
8915 Added functions: silc_server_send_remove_channel_user and
8916 silc_server_remove_channel_user into server.[ch].
8918 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8919 lib/silccore/silcpacket.h. However, they are not implemented
8922 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8924 * Fixed joining to a channel and sending channel messages
8925 between server and router. The channel message sending should
8926 now work inside a cell.
8928 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8930 * Fixed the private message sending between server and router.
8931 The private message sending should now work inside a cell.
8933 * Added silc_server_replace_id into server.[ch] to replace
8934 existing ID in the SILC network.
8936 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8937 and silc_idlist_replace_server_id into idlist.[ch] in server.
8939 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8941 * Fixed the server to server connections. Server can again now
8942 connect to router. Router to router connections probably does
8945 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8947 * Added dynamic protocol registering support. Now protocols can
8948 registered and unregistered on the fly. Patch by cras.
8950 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8952 * Added lib/contrib directory to hold routines that some platforms
8953 don't have but are needed by SILC.
8955 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8956 into lin/contrib to provide getopt() and getopt_long() for
8957 those who don't have it.
8959 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8961 * Added AWAY command to client. When away message is set and
8962 client receives a private message packet the client automatically
8963 replies to the sender with the away message.
8965 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8966 bug seemed to be the cause of recent problems when compiling
8969 * Added version detection support to SKE protocol specification
8970 and added the new changes to the SKE implementation as well.
8971 There were other minor changes in the SKE protocol as well.
8973 Many changes in lib/silcske/silcske.[ch] and in
8974 lib/silcske/payload.[ch].
8976 * Added ^U functionality, clear input line. Patch from cras.
8978 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8980 * Mainly small bugfixes on core library. Fixed some debugging
8981 logging and buffer overflow in silclog.c.
8983 * Updated config.sub and config.guess on the distribution tree.
8985 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8987 * Added command lagging support in server. Client may execute
8988 commands now only once in two seconds.
8990 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8992 * Optimized packet reception. MAC computation and checking is now
8993 also more optimized. A lot previously duplicated code is now
8994 used as generic by both client and server.
8996 * Fixed key pair generation in clientutil.c
8998 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9000 * Added into lib/silccore/silcbufutil.[ch] new function;
9001 silc_buffer_realloc.
9003 * Moved generic packet sending/encryption functions to
9004 lib/silccore/silcpacket.[ch] from client and server. Some
9005 rewriting of the functions.
9007 * Moved all generic packet reception/decryption functions to
9008 lib/silccore/silcpacket.[ch] from client and server. The
9009 packet processing is now much cleaner in both client and server.
9010 These were major changes in both client and server.
9012 * Created many common functions in server to do packet sending.
9013 Previously code were duplicated a lot, this has been removed
9016 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9018 * Rewrote major parts of the ID cache system. Don't know
9019 whether it is better now or not but at least the API is more
9022 * Major rewrite on ID cache stuff on client because of the ID
9023 cache API changes. Added idlist.c to client.
9025 * Also major rewrite on ID cache stuff on server as well.
9026 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9027 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9028 in hand, instead they are all put into the ID cache system now.
9029 All server_idlist_* routines uses ID cache now instead of
9030 traversing its own lists (those lists does not exist anymore).
9031 SilcIDList though still exists. Also, SilcXXXEntry's are
9034 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9036 * Finally made the SKE implementation compliant to the protocol
9037 specification. All mp integers are now binary encoded as
9038 opposed being HEX encoded.
9040 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9043 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9044 functions: silc_[encode/decode]_pem. Also added function
9045 silc_encode_pem_file to PEM encode with newlines ('\n') for
9048 * SILC public keys are now encoded either PEM or binary. Same
9049 option is for private keys as well. By default private keys
9050 are binary encoded and public keys PEM encoded. Silly HEX
9051 encoding were removed.
9053 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9054 function to create fingerprints.
9056 * Fixed a bug in SHA1; does not change the original data anymore.
9058 * Partly implemented INFO command on client and server side.
9059 Fixed CLEAR command. Changes to SERVER command; show current
9060 server(s) when giving command without arguments. Added
9061 VERSION command to client.
9063 * Added check to server that unregistered connections cannot
9064 execute commands (unless it is specificly allowed).
9066 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9068 * Fixed screen refresh.
9070 * Fixed channel joining bug from client. On some circumstances
9071 client tried to join to a channel it had already joined.
9073 * Added public key verification process into client's protocol.c.
9074 The client now verifies the public key from user and saves
9075 it into ~./silc/serverkeys/ directory.
9077 Added into: clientutil.[ch]: silc_client_verify_server_key.
9079 * Changed SKE protocol's silc_ske_initiator_finish function
9080 to accept callback function that verifies the received public
9081 key. Removed old silc_ske_verify_public_key function.
9083 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9085 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9086 silc_pkcs_private_key[_data]_set.
9088 * Made the password and public authentication more cleaner in
9089 server's protocol.c.
9091 * Removed historic and obsolete protocol `channel_auth' from
9092 both client and server.
9094 * Removed wrong way of sending command status messages from
9095 server to client in server's command.c. The old way violated
9096 protocol specification.
9098 Changes to silccore/silccommand.[ch]: removed
9099 silc_command_encode_status_payload -> not needed anymore,
9100 changed silc_command_encode_payload_va to accept extra
9101 argument on variable argument list. The argument type must
9102 now be provided to the function. Also, added new function:
9103 silc_command_encode_reply_payload_va which is same as
9104 normal command_encode_payload_va except command status type
9105 is provided as extra argument.
9107 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9109 * Added ~./silc directory handling. The directory includes the
9110 public and private keys for the client.
9112 Added silc_client_check_silc_dir, silc_client_create_identifier
9113 and silc_client_load_keys.
9115 * Implemented SILC protocol compliant public key. Added public
9116 and private key saving to and loading from files.
9118 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9119 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9120 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9121 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9122 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9124 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9125 silc_pkcs_load_[public/private]_key.
9127 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9129 * Added silc_server_get_route (route.[ch]) to get connection
9130 data for the fastest route for given ID.
9132 * Implemented INVITE command on client and server. The command
9133 were re-defined in the SILC Protocol Specification and the
9134 implementation now complies with the specification.
9136 * Implemented PING command on client and server.
9138 * Implemented NAMES command on client and server. The server side
9139 supports currently only normal server not router server yet.
9140 Some changes to NAMES definition in SILC protocol specification.
9142 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9144 * Implemented LEAVE command on client and server.
9146 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9147 again. This change was made to the protocol as well. Server
9148 should not violate the protocol specification anymore.
9150 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9152 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9153 was tested. SOCKS4 was not but should work anyway.
