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

1085 silc_ske_parse_version mistakenly checked wrong version,
1086 after it replaced the start payload. Affected files are
1087 lib/silcske/silcske.[ch].
1089 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

1093 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1094 Affected files lib/silcutil/silcstrutil.[ch].
1096 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1097 files are lib/silcutil/silcstrutil.[ch].
1099 * Defined that the security property fields in SKE SHOULD be
1100 UTF-8 encoded, defined that version string MUST be US-ASCII
1101 encoded, defined that passphrases sent in connection
1102 authentication protocol MUST be UTF-8 encoded. Implemented
1103 these to the client and server. Defined also that other
1104 passphrases sent in the protocol MUST be UTF-8 encoded.
1105 Affected files are lib/silcske/silcske.c,
1106 lib/silcclient/protocol.c, silcd/protocol.c,
1107 silcd/serverconfig.c, and lib/silccore/silcauth.c.

1110 need the SilcSocketConnection which should not be visible
1111 to application. Affected files are lib/silcclient/client.c
1112 and lib/silcclient/silcclient.h.
1114 * Rewrote the text for Private Message Key Payload in the
1115 protocol specification. Protocol TODO #11.
1117 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1119 * Upgraded the protocol version to 1.1, updated protocol specs
1122 * Added the nickname as new argument to NICK_CHANGE notify and
1123 added it to protocol specs and implemented it to client and
1124 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1125 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1126 lib/silcclient/client_notify.c.
1128 * Added the killer's client ID to the KILLED notify and added
1129 it to protocol specs and implemented it to client and server.
1130 Protocol TODO #13. Affected files are silcd/command.c,
1131 silcd/packet_receive.c, packet_send.[ch],
1132 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1133 The killer's client entry is now returned to application in
1134 the `notify' client operation.
1136 * Fixed the Max Argument fields that had too large value set
1137 in the protocol specs. Protocol TODO #14.
1139 * Added the LEAVE command reply to return the ID of parted
1140 channel. Updated protocol specs and implemented it to the
1141 client and server. Protocol TODO #15. Affected files are
1142 silcd/command.c, lib/silcclient/command_reply.c. The channel
1143 entry is now returned to application in the `command_reply'
1146 * Rewrote the version SKE version checking in client libary
1147 and in server to use the silc_parse_version_string. Affected
1148 files are lib/silcclient/protocol.c, silcd/protocol.c.
1150 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1151 commands that was missing it, and updated protocol specs and
1152 the server implementation. Protocol TODO #10. The affected
1153 file is silcd/command.c.
1155 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1156 generic reply to a generic request (REQUEST flag), and
1157 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1158 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1159 to define the payload for DATA flag. Added the flags to
1160 the implementation. Protocol TODO #9. Affected file is
1161 lib/silccore/silcchannel.h.
1163 Changed the client library to return the message length
1164 to application as well in the channel_message and private_message
1165 client operations. Affected files are
1166 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1167 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1168 and lib/silcclient/client_ops_example.c.
1170 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1171 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1172 the channel. Updated protocol specs and impelemented this
1173 to client and server. Protocol TODO #6. Affected files are
1174 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1175 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1177 Added new options m and M to CMODE command in Irssi SILC
1178 client to set these modes.
1180 * Deprecated all administrative commands from SILC protocol
1181 since they are highly implementation specific commands.
1182 Updated protocol specs. Moved the old commands in
1183 implementations to private range of command types. Affected
1184 files are silcd/command.c, lib/silcclient/command.c and
1185 lib/silcclient/command_reply.c. Protocol TODO #8.
1187 * Fixed a bug in server where sending unknown command crashes
1188 the server. Affected file silcd/command.c.
1190 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1192 * Added SILC_PROTOCOLVERSION macro to check protocol version
1193 of a socket connection. The affected file is
1194 lib/silcutil/silcsockconn.h.
1196 * Added better error logging in rekey protocol. Affected file
1199 * Do not check public key types in SKE during rekey. Affected
1200 file lib/silcske/payload.c.
1202 * Fixed the rekey protocol with PFS, which was totally broken.
1203 Affected file silcd/protocol.c.
1205 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1207 * Some client implementations quit network by doing first LEAVE
1208 and then immediately SIGNOFF (like Bombyx). We now do check
1209 after a short time after LEAVE notify and check whether the
1210 client is still valid after LEAVE, and if not we remove it from
1211 cache. Affected file is lib/silcclient/client_notify.c.
1213 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1215 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1216 it's good not to have security holes here.
1218 * Fixed a negative refcount situtuation for the config context.
1219 Affected file is silcd/serverconfig.c.
1221 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1223 * ROBOdoc documented lib/silcutil/silcutil.h.
1225 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1227 * Optimized even more the SilcPacketContext structure. Now
1228 totally saved 16 bytes of memory per context after optimization.
1229 Affected files are lib/silccore/silcpacket.[ch].
1231 * Made strict checks for valid SILC IDs. Affected file is
1232 lib/silccore/silcid.c.
1234 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Changed the object argument for silc_cipher_register,
1237 silc_hash_register, silc_hmac_register and silc_pkcs_register
1238 to const. Affected files are lib/silccrypt/silccipher.[ch],
1239 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1241 * Changed the silc_get_username and silc_get_real_name to
1242 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1244 * Fixed the Irssi SILC Client to use the silc_get_username and
1245 silc_get_real_name insted of glib routines since the glib
1246 routines only corrupt stack. Fixes the Irssi SILC to work in
1247 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1249 * Fixed the Irssi to not use g_get_home_dir since it crashes
1250 or returns garbage on cygwin and corrupts stack. Added function
1251 get_home_dir to Irssi routines. Affected files are
1252 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1254 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Made some structure optimizations. SFTP memory FS MemFSEntry
1257 entry structure. Optimized SilcTask structure. Optimized
1258 SilcPacketContext structure.
1260 Affected files lib/silcsftp/sftp_fs_memory.c,
1261 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1263 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * And yet again reverted back the config thing since Johnny
1266 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1269 * Fixed memory leaks from config object. Affected files are
1270 silcd/serverconfig.[ch].
1272 * Added support for adding new connections to the server in rehash.
1273 After rehash they take effect.
1275 Added support for changing the maximum allowed connections in
1276 rehash. The number can grow but going smaller is not supported.
1278 Added function silc_server_num_sockets_by_remote to the
1279 silcd/server_util.[ch].
1281 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1283 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1285 * Added preliminary checking during config parsing for a valid
1286 public/private key and removed further checks in the code.
1287 Affected files are silcd/serverconfig.[ch], server.c.
1289 * Moved functions silc_server_drop() and silc_server_daemonise()
1290 from server.c to silcd.c since they are stricly related to
1291 the application activity.
1293 * Reverted a small part of the automatic ref/unref since
1294 it caused a double unref in some situations. Affected
1295 files are silcd/silcd.[ch], server.c, serverconfig.c.
1297 * Added some .cvsignore files in the lib directory.
1299 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Fixed silc_net_gethostbyaddr to correctly resolve by
1302 address. Affected file lib/silcutil/silcnet.c.
1304 * Fixed the notify relaying to client. The HMAC to be used
1305 with relayed packets ws wrong and caused decryption failure
1306 at the client end. Affected file is silcd/packet_receive.c.
1308 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1310 * Created new branch silc_protocol_1_0_branch.
1312 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1314 * Changed the silc_server_config_* routines to be SilcServer
1315 independent. They are now officially application specific code
1316 and not part of generic server implementation. Affected files
1317 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1319 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1321 * Added automatic referencing of config context in the
1322 silc_server_config_alloc, and automatic unreferencing in the
1323 silc_server_config_destroy. Affected files are
1324 silcd/serverconfig.[ch], silcd/silcd.c.
1326 * Fixed the silc_log_quick handling in the logging routines.
1327 It didn't log quickly when it was TRUE. Affected file is
1328 lib/silcutil/silclog.c. Also the flush delay was set even
1329 if it was 0 in config file. Affected file is
1330 silcd/serverconfig.c.
1332 * Added support for changing key pair of the server in rehash.
1333 Affected file silcd/server.c.
1335 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1338 too early, before getting the channel entry. Affected file
1339 is silcd/packet_receive.c.
1341 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1343 * Added functions silc_server_config_[ref/unref], these are used
1344 to prevent that the config object is destroyed.
1346 No longer directly affect global variables silc_log_quick and
1347 silc_log_delay, they are first cached inside the config object
1348 and then applied with silc_server_config_setlogfiles().
1350 silc_server_config_set_defaults() is now internal to
1351 serverconfig.c, there are no reasons to show this internal stuff
1354 Affected files are silcd/serverconfig.[ch].
1356 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1357 fprintf's to stderr, since some code may be executed again after
1358 the server went into the background. Affected files are
1361 * Added rehash support. Added function silc_server_rehash() that
1362 will perform all the basic tasks of the rehashing procedure.
1364 * Added command line option `-x, --hexdump'. This will enable the
1365 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1366 The option `--hexdump' implies `--debug'.
1368 * Fixed a bad bug in the logging APIs (silcutil library) where
1369 the application would crash after calling silc_log_reset_all().
1371 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed the KICKED notify handling in client library to
1374 correctly remove the channel and all entries from the
1375 channel when I was kicked. This bug crashed the client.
1377 Fixed yet another but in KICKED notify handling to remove
1378 the kicked client correctly from the channel.
1380 Affected file is lib/silcclient/client_notify.c.
1382 * Fixed a minor bug in looking up correct client entry
1383 in KICKED notify in server. Affected file is
1384 silcd/packet_receive.c.
1386 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1387 sources correctly to distribution. Fixes --with-gmp option.
1389 * Removed the manual rehashing from ID Cache, and changed it
1390 to use the SILC Hash Table's auto rehash feature. Affected
1391 file is lib/silccore/silcidcache.c.
1393 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Fixed a bug in the silc_client_nickname_format function that
1396 handles the multiple same nickname formatting. Two clients
1397 with same nickname caused problems after the first one left
1398 and rejoined. It didn't format the nickname correctly.
1399 Affected file is lib/silcclient/idlist.c.
1401 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1403 * Don't change the topic if olod topic is same as new one.
1404 Affected file is silcd/packet_receive.c.
1406 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1408 * Added cross-reference support to the SILC Documentation
1409 generator. All types across all HTML files are now cross-
1410 referenced. Affected files util/robodoc/generator.c and
1411 scripts/silcdoc/silcdoc.
1413 * Added file lib/silcutil/silctypes.h to include all the
1414 arithmetic type definitions and some macros. Removed
1415 includes/bitmove.h and moved macros to silctypes.h.
1417 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1421 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1423 * Added `type' argument to silc_id_payload_parse_id function which
1424 now returns the type of the ID to the sent pointer. Affected
1425 file is lib/silccore/silcid.[ch].
1427 * Added check for CMODE_CHANGE notify type that mode change is
1428 allowed by the sender. Affected file silcd/packet_receive.c.
1430 * Added check for CUMODE_CHANGE notify type that mode change is
1431 allowed by the sender. Affected file silcd/packet_receive.c.
1432 Added the ID type as CUMODE_CHANGE notify type as argument
1433 to the `notify' client operation. Affected files are
1434 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1436 * Added function silc_client_add_server to the client library.
1437 Added support for resolving also channel and server info when
1438 received unknown entity in notify packet. Affected files are
1439 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1441 * Added function silc_command_get_status to return the command
1442 status from the command reply's argument payload. Affected files
1443 are lib/silccore/silccommand.[ch].
1445 * Added check for KICKED notify type that the kicking is
1446 allowed by the client. Affected file silcd/packet_receive.c.
1448 * Created function silc_get_input which can be used to get input
1449 (echo on or off) from user on command line. Affected files are
1450 lib/silcutil/silcutil.[ch].
1452 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1454 * Optimized silc_server_packet_relay_to_channel function.
1455 Added new function silc_channel_message_payload_encrypt which
1456 can be called directly if channel message payload needs to
1457 be encrypted and is already encoded (no need to call _encode
1458 function). Packet relaying is now done by router without any
1459 extra memory allocations. Affected files are
1460 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1461 silcd/packet_send.c.
1463 * Fixed the INVITE notify handling. It took wrong arguments
1464 as invite list and invite delete. Affected file is
1465 silcd/packet_receive.c.
1467 * Added check for TOPIC_SET notify type that the topic change is
1468 allowed by the client. Affected file silcd/packet_receive.c.
1470 * Added check for INVITE notify type that inviting is allowed by
1471 the client. Affected file silcd/packet_receive.c.
1473 * Changed the silc_server_client_on_channel to return the
1474 SilcChannelClientEntry as well. Moved the function
1475 silc_server_check_cmode_rights to server_util.[ch].
1476 Affected files are silcd/server_util.[ch], silcd/command.c.
1478 * Added function silc_server_check_umode_rights to check whether

1480 UMODE_CHANGE notify type that the umode change is allowed
1481 by the client. Affected files are silcd/server_util.[ch],
1482 silcd/packet_receive.c and silcd/command.c.
1484 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1486 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1487 ID length. It ignored that ID can be IPv6 based as well.
1488 Affected file lib/silccore/silcpacket.h.
1490 * Fixed the silc_id_id2str and silc_id_str2id to take the
1491 IPv6 address offset's into consideration. Affecte file is
1492 lib/silccore/silcid.c.
1494 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed the internal Unix scheduler functions to check for
1497 NULL context they may receive. The affected file is
1498 lib/silcutil/unix/silcunixschedule.c.
1500 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1502 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1503 can specify different directory with --home command line
1504 parameter. Affected files irssi/src/silc/core/client_ops.c,
1507 * SILC-specific commands aren't now executed if the active server
1508 isn't of SILC-type, so there won't be problems with having
1509 IRC and SILC protocol support in same client. Affected files
1510 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1513 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * Improved the signal support in SILC Schedule. Added new
1516 function silc_schedule_signal_call which is used by application
1517 to mark a signal to be called. It is now safe to perform
1518 any kind of tasks in signal callbacks since it is guaranteed
1519 that the application specified signal callback is called
1520 after the signal is over. Affected files are
1521 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1523 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Added `name' field to SilcChannelPrivateKey to represent
1526 application given name for the key. Moved also the context from
1527 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1528 Added the `name' argument also to the function
1529 silc_client_add_channel_private_key.
1531 Added function silc_client_current_channel_private_key to set the
1532 current channel private key in use.
1534 Added "change" command to KEY command which can be used to change
1535 the current channel private key. Bound the command also to
1536 alt+K (Alt+Shift+k).
1538 Also affected files lib/silcclient/client_channel.c,
1539 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1541 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1543 * Added silc_rng_get_byte_fast function in to the
1544 lib/silccrypt/silcrng.[ch].
1546 * Changed the interface of silc_packet_assemble and the
1547 silc_packet_send_prepare. If silc_packet_assmble is now
1548 called the application does not call silc_packet_send_prepare
1549 because the library will call it automatically. These
1550 interfaces now also return a reference to the outgoing buffer
1551 which includes the assembled packet, which the application can
1552 use to encrypt the packet.
1554 Affected files are lib/silccore/silcpacket.[ch],
1555 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1556 silcd/packet_send.c, server_backup.c and packet_receive.c.
1558 * Fixed a packet sending bug on very high load, where outgoing
1559 packet queue wasn't handled correctly and packets got corrupted.
1560 Affected files are lib/silcutil/*/silc*sockconn.c,
1561 lib/silcclient/client.c and silcd/server.c.
1563 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1565 * Added macro SILC_PACKET_DATALEN which can be used during
1566 packet assembling to check whether the data to be added to
1567 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1568 len is truncated until it fits it.
1570 Added checks for maximum length of channel message payload and
1571 private message payload also.
1573 Added checks for maximum packet length in server and in
1576 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1577 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1578 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1579 lib/silcclient/client_prvmsg.c.

1583 * Added silc_server_packet_queue_purge call to the
1584 silc_server_disconnect_remote to assure that all data in the
1585 queue before disconnecting is sent to the network. Affected
1586 file silcd/server.c.
1588 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1590 * Added the deleting of server's own ID cache entry to the
1591 silc_server_free function. Free also everything else that
1592 has been allocated in silc_server_init. The affected file
1595 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1597 * Added functions silc_parse_version_string, silc_version_to_num,
1598 and silc_ske_parse_version to parse SILC protocol style version
1599 strings. Affected files lib/silcutil/silcutil.[ch] and
1600 lib/silcske/silcske.[ch].
1602 * Added new configuration params: version_protocol, version_software
1603 and version_software_vendor to specify what version the remote
1604 host must at least be to be able to connect to server. The vendor
1605 string can be regex matched too. Added new function
1606 silc_server_connection_allowed to check maximum number of allowed
1607 connections, and allowed versions for incoming connections.
1608 Affected files are silcd/server.c, server_util.[ch] and
1611 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1613 * Added preliminary support for signals in scheduler. The
1614 signals we care about are now blocked always when the scheduler
1615 is locked. This way we can synchronise the use of signal with
1616 scheduler. It is guaranteed that when signal occurs the scheduler
1617 is not locked, and thus new tasks can be safely added to the
1620 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1621 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1622 Added new platform specific routines
1623 silc_schedule_internal_signals_[un]block and
1624 silc_schedule_internal_signal_[un]register.
1626 Added new functions to SILC Schedule API:
1627 silc_schedule_signal_[un]register. Each signal that application
1628 is going to use should be registered to the scheduler.
1630 Affected files are lib/silcutil/silcschedule.[ch],
1631 lib/silcutil/*/silc*schedule.c.
1633 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1635 * Check for unauthenticated client and server in the
1636 silc_server_new_client and silc_server_new_server functions.
1637 Affected file silcd/packet_receive.c.
1639 * Added function silc_string_is_ascii to check whether given
1640 string is 7-bit ASCII string. Affected files are
1641 lib/silcutil/silcutil.[ch].
1643 * Added function silc_id_is_valid_server_id into the
1644 silcd/serverid.c and added checking for valid Server ID's in
1645 silc_server_new_server. The Server ID must always be based
1646 on the server's public IP address.
1648 * Added logging of DISCONNECT packet message in the server.
1649 Affected file silcd/server.c.
1651 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1653 * Changed all library interfaces that use Global RNG to also
1654 accept SilcRng as argument. Affected files are
1655 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1656 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1657 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1658 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1659 lib/silccrypt/rsa.c.
1661 * Added function silc_pkcs_generate_key to the
1662 lib/silccrypt/silcpkcs.[ch] for applications so that they
1663 don't need to do pkcs->pkcs->init calls anymore.
1665 * Remove SilcSocketConnection from the SFTP API since it really
1666 wasn't needed there. The application has the information
1667 saved in its contexts anyway and the SFTP layer doesn't need
1668 know about it. Affected files lib/silcsft/silcsftp.h and
1669 lib/silcsftp/sftp_[server/client].c.
1671 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1672 The SilcSimContext is not SilcSim.
1674 * Fixed possible buffer overflows in silc_id_render in the
1675 lib/silcutil/silcutil.c.
1677 * On EPOC the global crypto module lists are not used at all
1678 in the crypto library. Added support for using the constant
1679 algorithm list on EPOC. Affected files are
1680 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1683 * Fixed the handling of third parameter of KICKED notify, since
1684 it was mistakenly updated to SILC Protocol 1.0 even though it
1685 is to be included in 1.1. Since it is not in 1.0 it is not
1686 mandatory, and this fix now handles it only if it is provided,
1687 and it is not error if it is not provided. Affected file
1688 lib/silcclient/client_notify.c.
1690 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1692 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1693 client. Affected file irssi/src/silc/core/client_ops.c.
1695 * Merged with Irssi 0.8.4 from irssi.org CVS.
1697 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Check for valid socket connection in client entries before
1700 sending any messages. Fixes a crash, but doesn't fix some
1701 other underlaying bug that is lurking there. Affected
1702 file silcd/packet_send.c.
1704 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1706 * $usermode, $cumode and $cumode_space expandos shouldn't do
1707 anything with non-SILC server records. Affected file
1708 irssi/src/silc/core/silc-expandos.c
1710 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1712 * Fixed the silc_net_check_[host/local]_by_sock to support
1713 IPv6 bound sockets as well. Now they can return IPv6 addresses
1714 as well. Affected file lib/silcutil/silcnet.c.
1716 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1717 Affected lib/silcutil/unix/silcunixnet.c.
1719 * Fixed ID rendering (at least on some platforms, not NetBSD)
1720 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1722 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1724 * Added silc_hash_public_key and silc_hash_public_key_compare
1725 functions to be used with SilcHashTable. They can be used to
1726 hash public keys and compare public keys in hash table. Affected
1727 file lib/silcutil/silcutil.[ch].
1729 * Added support for specifying multiple public keys for Client
1730 connection section in server configuration file. This makes it
1731 possible to accept multiple public keys from same host, or to
1732 make a section that accepts any incoming host, and have the
1733 accepted public keys listed in the section.
1735 Added functions silc_sever_[find/get]_public_key, added the
1736 support for this actually to all connection sections but only
1737 the Client section is currently allowed to specify multiple
1740 Affected files are silcd/server.c, server_internal.h,
1741 command.c, protocol.c, server_util.[ch], packet_receive.c.
1743 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1745 * Merged Irssi 0.8.2 from irssi.org CVS.
1747 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1749 * If silc_debug is TRUE, also output standard logging messages
1750 to stderr with the debug output.
1752 Made silc_log_reset_all() flushing all channels before returning.
1753 Also fixed some documentation typos.
1755 Affected files are lib/silcutil/silclog.[ch].
1757 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Fixed the server to check correctly the amount of connections
1760 from single host, by checking also the type of the connection.
1761 Fixed also the comparison of number of connections and number
1762 of allowed connections. Affected files are silcd/server.c,
1765 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1767 * Fixed the USERS command reply to save the user's mode on the
1768 channel as well. Fixed JOIN command reply to check whether a
1769 client is on channel already and not join it twice. Affected
1770 file lib/silcclient/command_reply.c.
1772 * Added new file silc-expandos.c into irssi/silc/core/ to return
1773 various stuff for various signal for the statusbar etc. updating.
1774 Now Irssi SILC client prints channel user modes etc. on the
1777 * The user mode (like server/router operator changes) is now shown
1778 on the Irssi SILC client's statusbar. The affected files are
1779 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1781 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1783 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1784 to SILC_SCHEDULE_[UN]LOCK macros.
1786 * Added more error printing to logs in server code. Affected
1787 files silcd/server.c and silcd/protocol.c.
1789 * Fixed -S option parsing in Irssi SILC Client. Affected file
1790 irssi/src/silc/core/silc-core.c.
1792 * Added silc_buffer_alloc_size function. Affected file is

1807 * Fixed the buffer formatting and unformatting routines to
1808 check the size of 64 bits types with sizeof(). Affected
1809 file is lib/silcutil/silcbuffmt.c.
1811 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1815 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1817 * Changed all integer type names:
1818 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1819 to avoid collisions with other libraries using same type names
1822 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1824 * Added `prefer_ipv6' argument to the functions
1825 silc_net_gethostbyname[_async]. If it is TRUE it will return
1826 IPv6 address over IPv4. If FALSE IPv4 address is returned
1827 even if IPv6 address was found. Affected files
1828 lib/silcutil/silcnet.[ch].
1830 * Added support silc_net_create_connection[_async] to fallback
1831 to IPv4 address if IPv6 address could not be used (like if
1832 it doesn't work on a specific system). Affected file in
1833 lib/silcutil/unix/silcunixnet.c.
1835 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1837 * Added silc_schedule_reinit function to do the enlarging
1838 of the max tasks handling capabilities of the scheduler.

1841 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Added automatic extern "C" { ... } for C++ compilers so the
1844 application does not need to define them. Affected file
1845 includes/silcincludes.h.
1847 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1848 old name went against naming convention. Applications now
1849 include "silcclient.h" instead of "clientlibincludes.h".
1850 Removed includes/clientlibincludes.h, it is redundant now.
1852 * Renamed includes/version.h to silcversion.h.
1854 * Added really preliminary support for OS/2 into the util
1855 library. Only thread & mutex API is implemented, others
1856 are still to be implemented. Created the lib/silcutil/os2/
1857 directory. Created also file includes/silcos2.h.
1859 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1864 includes/silcbeos.h.
1866 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1868 * Added proper initializations to silc's irssi code, so it's
1869 now possible to load it as module. Affected files
1870 irssi/src/silc/core/silc-core.c,
1871 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1890 * Added `user_count' to the SilcChannelEntry which now tells the
1891 number of users on the channel. The user count is now saved
1892 in normal server of global channels as well. Affected files
1893 silcd/server.c, idlist.h, packet_receive.c and command.c.
1895 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1896 include file utility functions.
1898 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1899 instead of calling directly OS routines.
1901 * Fixed NICK change printing in Irssi SILC Client. Fixed
1902 KICKED notify printing in Irssi SILC Client. Affected file
1903 irssi/src/silc/core/client_ops.c.
1905 * Fixed a NICK change bug in client library, to not recreate the
1906 client_entry->channels hash table everytime nick is changed.
1907 Affected file lib/silcclient/client.c.
1909 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1911 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1912 the SKE interface a bit.
1914 * Fixed padding problem in PKCS#1. The padding was not actually
1915 random since the random number generator was used incorrectly.
1916 This security bug affects only when encrypting with PKCS#1, and
1917 it is not currently used at all in SILC. SILC only use signing
1918 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1920 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1932 key_exchange_timeout, conn_auth_timeout, connections_max,
1935 Implemented all the new config settings handling in the server.
1937 Optimized the use of SKE Mutual flag usage. Use it only
1938 if connection authentication protocol is not based in public
1941 Renamed all SilcServerConfigSection* to SilcServerConfig*
1942 to have a bit shorter names.
1944 Affected files silcd/serverconfig.[ch], server.[ch], and

1978 is now done in silc_core_init() which also fixes autoconnecting
1981 Affected files irssi/src/silc/core/silc-core.c,
1982 irssi/src/fe-text/silc.c.
1984 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1986 * Added new configuration options and blocks:
1987 keepalive_secs, reconnect_count, reconnect_interval,
1988 reconnect_interval_max, reconnect_keep_trying and
1989 require_reverser_lookup. Added ConnectionParam block, and
1990 implemented the connection parameters when connecting as
1991 initiator and when accepting connections as responder.
1993 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1994 whether given configuration value has been given already.
1996 Affected files silcd/serverconfig.[c], server.[c].
1998 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1999 algorithm parts and created new file silcalgs.conf, that
2000 is now included from the example_silcd.conf.in.
2002 * Optimized the silc_server_connect_to_router_second to take
2003 the connection configuration object from the SilcServerConnection
2004 object instead of finding it during the connecting phase.
2005 Added the configuration object to SilcServerConnection struct.
2006 Affected files silcd/server_internal.h, server.c.
2008 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2010 * Add the client on channel after it was resolved at the
2011 channel message receiving, and it was not already on the
2012 channel. Affected file lib/silcclient/client_channel.c.
2014 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2016 * Fixed the public key authentication to allocate always the
2017 destination signature buffer instead of using static buffer.
2018 Affected file silcd/protocol.c.
2020 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2029 config file, allowing both public key and passphrase based
2030 authentication to be set at the same time.
2032 Added `prefer_passphrase_auth' setting in config file which
2033 can be used to set to prefer passwd auth if both passwd and
2034 public key is set. If not set, public key is preferred.
2035 This has effect only when being initiator (responder will try
2038 Added support for authentication with passphrase and public key
2039 at the same time. The passphrase is tried first always since
2040 it is faster to check.
2042 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2044 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2086 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2088 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2090 * Fixed the file transfer's key agreement payload to include
2091 zero port also if the hostname is NULL because it could not
2094 Call file transfer monitor callback now also if error occurs
2095 during key agreement protocol.
2097 Changed the silc_client_file_send interface to return the
2098 SilcClientFileError instead of session id. The session ID
2099 is returned into pointer provided as argument.
2101 Check that the file exists locally before sending the
2102 file transfer request at all.
2104 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2106 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2107 error than can occur while key agreement protocol. Affected
2108 file lib/silcclient/silcapi.h.
2110 * Fixed the event_mode CMODE handler to not crash when mode
2111 is changed and +k mode is set in the channel. Affected file
2112 irssi/src/silc/core/silc-channels.c.
2114 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2115 SILC_LOG_WARNING to give out Warning and not Error. Affected
2116 file lib/silcutil/silclog.c.
2118 * Fixed the channel message payload decryption in the function
2119 silc_channel_message_payload_decrypt to not modify the original
2120 buffer before it is verified that the message decrypted
2121 correctly. Otherwise, next time it is called with correct
2122 channel key it won't encrypt since the payload is corrupted.
2123 Affected file lib/silccore/silcchannel.c.
2125 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2127 * Do not constantly resize the window. A fix patch by cras.
2128 Affected file irssi/src/fe-text/screen.c.
2130 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2132 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2133 Affected file lib/silcutil/silcnet.c.
2135 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2137 * Fixed a bug in hash table internal routine for traversing
2138 the table with foreach callback. The current entry may
2139 become invalid in the callback but it was referenced after
2140 the callback returned.
2142 Do not allow auto rehashing of hash table during the
2143 silc_hash_table_foreach operation, for same reasons as it is
2144 not allowed for SilcHashTableList. Affected files are
2145 lib/silcutil/silchashtable.[ch].
2147 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2149 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2150 Win32 DLL. extern's in header files are now declared with
2153 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2155 * Fixed private message handling. It used some old code that
2156 caused the client to crash. Affecte file is
2157 lib/silcclient/client_prvmsg.c.
2159 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2161 * Added function silc_client_add_channel,
2162 silc_client_replace_channel_id, and removed functions
2163 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2164 from client library.
2166 * Added cross reference of the joined channels to the
2167 SilcClientEntry, and changed the SilcChannelEntry's
2168 users list to SilcHashTable. The affected files are
2169 lib/silcclient/idlist.[ch].
2171 * Fixed a bug in hash table tarversing. While the hash table
2172 is traversed with SilcHashTableList the table must not be
2173 rehashed. It is now guaranteed that auto rehashable tables
2174 are not rehashed while tarversing the list. Also defined that
2175 silc_hash_table_rehash must not be called while tarversing
2176 the table. Added function silc_hash_table_list_reset that must
2177 be called after the tarversing is over. The affected files are
2178 lib/silcutil/silchashtable.[ch].
2180 * Changed all hash table traversing to call the new
2181 silc_hash_table_list_reset in server and in client library.
2183 * Added function silc_client_on_channel to return the
2184 SilcChannelUser entry if the specified client entry is joined
2185 on the specified channel. This is exported to application as
2186 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2188 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed founder regaining problem with JOIN command on normal
2191 server. The notify for mode change must be sent always and
2192 not only if !cmd->pending. Affected file silcd/command.c.
2194 * Fixed the WHOWAS command's reply sending to support the
2195 lists correctly. Affected file silcd/command.c.
2197 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2199 * When sending JOIN command to router for processing the
2200 sender's old command identifier was not saved back to the
2201 sender's command context, fixed now. The affected file is
2204 * Create the key in JOIN command of the router did not return
2205 the channel key, added check for this. Affected file is
2208 * Fixed a channel ID update bug in JOIN command reply. Do
2209 not directly upgrade the ID but call the function
2210 silc_idlist_replace_channel_id if the ID was changed.
2211 Affected file silcd/command_reply.c.
2213 * Fixed memory leaks from command calling if it would fail.
2214 Affected file silcd/command.c.
2216 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2218 * Applied patches from cras:
2220 Memory leak fixes around libaries, irssi window resize fix,
2221 new silclist.h and silcdlist.h, all extern inline changed to
2224 * Removed dotconf from lib/dotconf, not needed anymore.
2226 * Removed TRQ from lib/trq, not needed anymore.
2228 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2229 with server connections. Later this will be configurable
2230 in config file after new config file is done. Affected file
2233 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2235 * Fixed a crash in server related to channel announcements.
2236 Affected file silcd/server.c.
2238 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2240 * Fixed memory leaks in silc_server_create_new_channel*
2241 functions. Affected file silcd/server.c.
2243 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2244 which ID was changed. This way the router will send the
2245 user list for the channel again, and server won't be in
2246 desync in some rare circumstances. Affected file is
2247 silcd/packet_receive.c.
2249 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2251 * Check for NULL socket pointer in the function
2252 silc_server_packet_send_to_channel_real. Affected file
2253 silcd/packet_send.c.
2255 * Fixed the BAN notify handling to correctly remove ban
2256 list. Affected file silcd/packet_receive.c.
2258 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2260 * Fixed some header addition to Toolkit distribution in
2261 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2263 * Added lib/silcclient/client_ops_example.h as an template
2264 file for application programmers to quickly start using
2265 the SilcClientOperation functions in their application.
2266 Updated the lib/silcclient/README as well to tell about this
2267 nice file made available.
2269 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2271 * Call silc_server_remove_from_channels when removing client
2272 entry when NO_SUCH_CLIENT_ID was received. Affected file
2273 is silcd/command_reply.c.
2275 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2277 * Added server & router operator statistics updating. Affected
2278 file silcd/packet_receive.c and silcd/command.c.
2280 * Fixed the SERVER_SIGNOFF notify handling on normal server
2281 not to save the history information for clients. Same was
2282 fixed earlier in remove_clients_by_server function, but not
2283 here. Affected file silcd/packet_receive.c.
2285 * Raised the default connection-retry count from 4 to 7 in
2286 server. Affected file silcd/server.h.
2288 * Cancel any possible reconnect timeouts when we start the
2289 key exchange. Affected file silcd/server.c.
2291 * Do not reconnect on connection failure when SCONNECT was
2292 given. Affected files silcd/server.[ch].
2294 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2296 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2298 * Fixed the NICK command to always give the unformatted
2299 nickname to the one giving the NICK command. If unformatted
2300 nickname is cached already it will be formatted and the
2301 local entry will always get the unformatted nickname.
2302 Affected file lib/silcclient/idlist.c.
2304 * Fixed some double frees from client library commands.
2305 Affected file is lib/silcclient/command.c.
2307 * Fixed CUMODE command in server to assure that no one can
2308 change founder's mode than the founder itself, there was a
2309 little bug. Affected file silcd/command.c.
2311 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2313 * Removed the SilcClientCommandDestructor from the client
2314 libary, it is not needed anymore. Affected files are
2315 lib/silcclient/silcapi.h, command[_reply].[ch],
2316 client_notify, idlist.c.
2318 * Fixed GETKEY command to first resolve client, and then
2319 resolve the server only if the client was not found, instead
2320 of resolving both at the same time. Affected file is
2321 lib/silcclient/command.c.
2323 * Added silc_client_start_key_exchange_cb and lookup the
2324 remote hostname and IP address before starting the key
2325 exchange with server. The affected file is
2326 lib/silcclient/client.c.
2328 * The server's public key is now saved using the IP address
2329 of the server and not the servername for the filename.
2330 The hostname public key filename is checked as an fall back
2331 method if the IP address based filename is not found.
2333 Fixed the GETKEY command to save the fetched server key
2334 in correct filename.
2336 Print the remote server's hostname now when new key is
2337 received during connection process. Affected file is
2338 irssi/src/silc/core/client_ops.c.
2340 * Return always our own public key to the client if it asks
2341 for it with GETKEY command. Affected file silcd/command.c.
2343 * Removed the use_auto_addr variable from default config
2344 file since it was in wrong section. Affected file is
2347 * Fixed TOPIC_CHANGE notification to not route it when it
2348 was sent using silc_server_send_notify_to_channel function.
2349 Affected file silcd/command.c.
2351 * Fixed silc_server_send_notify_kicked to send the kicker's
2352 Client ID also, it was missing. Affected files are
2353 silcd/command.c, silcd/packet_send.[ch].
2355 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2357 * Do not save client history information in SERVER_SIGNOFF.
2358 Fixes the bug in normal server that it does not detect
2359 the client becoming valid after the server becomes back
2360 online. Affected file silcd/server_util.c.
2362 * Added `sock_error' field into the SilcSocketConnection
2363 context. When error occurs during socket operation (read
2364 or write) the error is saved. Added also new function
2365 silc_socket_get_error to return human readable socket error
2366 message. Affected files are lib/silcutil/silcsockconn.[ch],
2367 lib/silcutil/unix/silcunixsockconn.c, and
2368 lib/silcutil/win32/silcwin32sockconn.c.
2370 * The server now prints the socket error message in the
2371 signoff for client. Affected file silcd/server.c.
2373 * Fixed the `created' channel information sending from router
2374 to server in JOIN command. Checks now whether the channel
2375 really was created or not and set it according that.
2377 Fixed the JOIN command to use the client entry's current
2378 ID during the joining procedure instead of the one it sent
2379 in the command (it is checked though), since it can change
2380 between the packet processing and command processing, and
2381 would just case unnecessary pain in the client end. Affected
2382 file silcd/command.c.
2384 * Fixed a channel key payload sending to use correct channel
2385 ID when the server was forced to change the channel's ID by
2386 router. Router sent the key payload with the old Channel ID.
2387 Affected file silcd/packet_receive.c.
2389 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2391 * Call silc_server_save_channel_key only if the key payload
2392 was provided in the JOIN command's command reply. Affected
2393 file silcd/command_reply.c.
2395 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2397 * Fixed silc_mp_sizeinbase to return the value correctly with
2398 MPI. Affected file lib/silcmath/mp_mpi.c.
2400 * Fixed the stop_server signal to correctly stop the scheduler
2401 and gracefully stop the server when SIGTERM or SIGINT signals
2402 are received. Affected file silcd/silcd.c.
2404 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2406 * Simple handling of TERM and HUP signals. Also added some log
2407 flushing call around. Affected file is
2410 * Fixed small bugs in silclog.c. Now buffering output will take
2411 effect after 10 seconds since startup: This will ensure that
2412 no important startup messages are lost. Also output redirection
2413 will preserve original format ([Date] [Type] message).
2414 Affected file is lib/silcutil/silclog.c.
2416 * Added two options to the config file, in the logging section:
2417 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2418 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2420 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2422 * Do not print the warning about log files not being initialized
2423 more than once to avoid excess logging. Affected file is
2424 lib/silcutil/silclog.c.
2426 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2427 the SIM copying in make install in Makefile.am.pre.
2429 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2431 * Rewritten silclog APIs. Globally interesting changes follows:
2432 silc_log_set_files() changed to silc_log_set_file().
2433 silc_log_set_callbacks() changed to silc_log_set_callback().
2434 ROBOdoc documented silclog header file.
2435 SilcLogCb now returns bool to wether inihibit the default
2436 handler or not (to keep the old behaviour return always TRUE).
2437 The new APIs should also fix the problem of the
2438 silcd_error.log file that was written in the current directory.
2441 Log files streams will remain opened after silc_log_set_file()
2442 call, means less CPU usage notably on high traffic servers.
2443 File streams are now full buffered, and flushed to the disk
2444 every 5 minutes, lesses HD activity and CPU usage.
2445 Messages can be redirected, allowing admins to configure
2446 one single logfile for all server messages.
2447 the silc_log_quick global variable to activate fast-logging.
2448 Affected files lib/silcutil/silclog.[ch]
2450 * Changed some code to conform new silclog APIs. Affected
2451 files are doc/example_silcd.conf.in, silcd/server.c
2452 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2455 * Fixed a memory leak that could occur in some situations.
2456 Affected file silcd/serverconfig.c.
2458 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2460 * Added the silc_client_del_client to remove the client from
2461 all channels as well. Affected file lib/silcclient/idlist.c.
2463 * Fixed the client library to correctly remove the client
2464 from all channels when the client entry is being destroyed.
2465 Affected file lib/silcclient/client_notify.c, command.c.
2467 * Added auto-nicking support to the client library. If the
2468 applicatio now sets client->nickname it will be sent to the
2469 server after connecting by the library. This way for example
2470 SILCNICK (or IRCNICK) environment variables will have effect
2471 and always change the nickname automatically to whatever
2472 it is wanted. Affected file lib/silcclient/client.[ch].
2474 * Renamed silc_server_command_bad_chars to the
2475 silc_server_name_bad_chars and moved it to the
2476 silcd/server_util.[ch]. Added also new function
2477 silc_server_name_modify_bad to return nickname that
2478 includes bad characters as new nickname without those
2479 bad characters. This check and modify is now used in
2480 silc_server_new_client when the username is initially set
2481 as nickname, so it must be checked to be valid nickname.
2482 Affected file silcd/packet_receive.c.
2484 * The nickname length is now taken from the packet for real
2485 and not trusted to strlen() since it clearly can return
2486 wrong length for nickname including bad characters. This
2487 also applies to channel names. Affected file silcd/command.c.
2489 * Removed the lib/silcsilm/modules directory. Modules are now
2490 compiled into the lib/silcsim. Fixed the copying of the
2491 modules to follow symbolic links in Makefile.am.pre.
2493 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2495 * Fixed silc_string_regexify list creation. Fixes bugs with
2496 BAN and INVITE commands in server. The affected file is
2497 lib/silcutil/unix/silcunixutil.c.
2499 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Removed the command destructor entirely from the server's
2502 command and command reply routines. It is not needed, and
2503 its usage was buggy and caused crashes. Affected files are
2504 silcd/command[_reply].[ch].
2506 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Cancel protocol and NULL sock->protocol if timeout
2509 occurred during protocol. Affected file silcd/server.c.
2511 * Cancel protocol timeouts always before calling the final
2512 callback, to assure that after final callback is called
2513 no other state will be called for the protocol anymore.
2514 Affected file silcd/protocol.c.
2516 * Print error log if incoming connection configuration could
2517 not be found. Affected file silcd/server.c.
2519 * Fixed JOIN command to correctly save the founder mode
2520 to the client on normal SILC server, when the channel
2521 was created by the router. Affected file silcd/command.c.
2523 * Fixed LIST command (hopefully) to send correct reply
2524 packets. Affected file silcd/command.c.
2526 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * The silc_packet_receive_process now returns FALSE if the
2529 read data was invalid packet, and TRUE if it was ok.
2531 The server now checks that if unauthenticated connection
2532 sends data and its processing fails the server will close
2533 the connection since it could be a malicious flooder.
2535 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2537 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Make sure the warning about error opening a log file is
2540 printed only once and not everytime it fails (produces
2541 too much useless log). Affected file lib/silcutil/silclog.c.
2543 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2545 * Made the silc_server_daemonise() function more readable.
2546 Affected file silcd/server.c.
2548 * Pid file is now optional, the user may comment it out from
2549 the config file. Removed define SILC_SERVER_PID_FILE, we
2550 don't need a default any longer. Affected file
2551 configure.in.pre, lib/Makefile.am.pre.
2553 * Make some use of the pid file. The server now dies at startup
2554 if it detects a valid pid file on his path. The server would
2555 die anyway in this circumstance, because of the bind() failure.
2556 Affected file silcd/silcd.c.
2558 * No longer compiling lib/dotconf.
2560 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed JOIN command parsing not to crash. Affected file
2563 lib/silcclient/command.c.
2565 * Fied the NICK_CHANGE notify to add the new client entry
2566 even it is resolved. This removes an <[unknown]> nick
2567 thingy bug in the client. Affected file is
2568 lib/silcclient/client_notify.c.
2570 * Do not try to allocate 0 bytes (efence does not like it)
2571 in lib/silccore/silccomand.c when encoding payload.
2573 * Do not take IRCNICK as nickname in Irssi SILC client since
2574 it is not possible to set nickname before hand connecting
2575 the server (TODO has an entry about adding auto-nicking
2578 * Changed the silc_server_command_pending to check whether
2579 there already exists an pending entry with the specified
2580 command, command identifier and pending callback. This is
2581 to fix IDENTIFY and WHOIS related crashes that may register
2582 multiple pending commands with same identifier. Affected
2583 file silcd/command.c.
2585 * Fixed the server to reconnect to the router even if it
2586 was already reconnecting and EOF was received. This to
2587 fix a possibility that the server wouldn't ever try to
2588 auto-reconnect to the router. Affected file silcd/server.c.
2590 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Fixed the server's password authentication to use the
2593 length of the locally saved password, and not the one
2594 sent in the packet. Affected file silcd/protocol.c.
2596 * Fixed same password authentication problem in the
2597 Authentication Payload handling routines in
2598 lib/silccore/silcauth.c.
2600 * Yet another password authentication problem fixed with
2601 channel password handling in silcd/command.c.
2603 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * If first character of string in silc_parse_userfqdn is '@'
2606 then do not parse it. Affected file is
2607 lib/silcutil/silcutil.c.
2609 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed minor bug in IDENTIFY command reply sending, which
2612 caused various weird problems during JOIN when it was
2613 resolving names for users. Affected file silcd/command.c.
2615 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Fixed the IDENTIFY command reply sending to chech better valid
2618 clients. It was possible to send incomplete list of replies.
2619 Affected file silcd/command.c.
2621 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Added silc_client_command[s]_[un]register functions now to
2624 dynamically register the commands in client library. Removed
2625 the static table of commands. This allows the client library
2626 to call commands without causing the application to know about
2627 what commands library has called.
2629 Removed the INFO command reply kludge to detect when the command
2630 was called by library. Now library use its own command reply
2631 function for INFO command.
2633 Added function silc_client_command_call to call a command.
2634 Application can use it to call command, not access the structure
2637 Now all commands that are sent by the client library (not
2638 explicitly sent by application) use own command reply functions.
2640 Affected files around lib/silcclient/ and in
2641 irssi/src/silc/core/.
2643 * Fixed the WHOIS command reply sending to chech better valid
2644 clients. It was possible to send incomplete list of replies.
2646 Fixed the WHOIS and IDENTIFY to send the request to router
2647 if normal server did not do it and did not find any results.
2649 Affected file silcd/command.c.
2651 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Moved the internal data from SilcClient context into its
2654 own file, not accesible to application. Affected files
2655 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2656 and other files in client library.
2658 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * Added doc/examples installation target in Makefile.am.pre.
2663 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2666 commands the found client entry will be removed from the
2667 cache, after notifying application about the error. Affected
2668 file lib/silcclient/command_reply.c.
2670 * Changed the /MSG to check for exact nickname user gave, and
2671 not let `nick' match `nick@host' if it is only one found. Now,
2672 user must type the exact nickname (like nick@host2) even if
2673 there are no more than one same nicks found. This is to avoid
2674 a possibility of sending nickname to wrong nickname since
2675 `nick' could match `nick@host'. Affected file is
2676 irssi/src/core/silc-servers.c.
2678 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Do not print "you are now server operator" or similar when
2681 giving /away command. Affected files are
2682 irssi/src/silc/core/client_ops.c, silc-servers.h.
2684 * Made the silc_server_command_pending_error_check to send
2685 the same command reply payload it received back to the
2686 original sender of the command. This way all arguments
2687 that was received by the server will be received by the
2688 client too. Affected file silcd/command.c.
2690 * Added the silc_idcache_add to return the created cache entry
2691 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2693 * Add global clients to expire if they are not on any channel.
2694 This is because normal server will never know if they signoff
2695 if they are not on any channel. The cache expiry will take
2696 case of these entries. This is done by normal servers only.
2697 The affected files are silcd/command_reply.c,
2698 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2700 * If server receives invalid ID notification for WHOIS or
2701 IDENTIFY and the ID exists in the lists, it is removed.
2702 Affected file silcd/command_reply.c.
2704 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2705 in client then client entry that it matches is searched and
2706 the nickname is printed on the screen for user. Affected
2707 file irssi/src/silc/core/client_ops.c.
2709 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Use cache entry expire time in the LIST command reply to
2712 purge old entries from the cache after the LIST command
2713 reply has been received. This way we don't have non-existent
2714 entries in the cache for too long. Affected file is
2715 silcd/command_reply.c.
2717 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * If we are normal server, and we've not resolved client info
2720 in WHOIS or IDENTIFY from router, and it is global client,
2721 we'll check whether it is on some channel. If it is not
2722 then we cannot be sure about its validity and will resolve it
2723 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2724 file silcd/command.c.
2726 * Search channel by name (if possible) rather than by ID
2727 in IDENTIFY command's command reply. Affected file is
2728 silcd/command_reply.c.
2730 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2733 Updated specs and implemented it. Affected file silcd/command.c,
2734 silcd/packet_send.c and silcd/packet_receive.c.
2736 * Implemented the <founder auth> payload handling in the JOIN
2737 command. If provided all conditions for channel joining
2738 except requirement to provide correct passphrase can be
2739 overrided by the channel founder. Updated the protocol specs.
2740 Affected file silcd/command.c.
2742 Added support for founder auth in JOIN command in client
2743 library. Fixed the parsing of the JOIN command now to support
2744 all options as they should be. The affected file is
2745 lib/silcclient/command.c.
2747 * Optimized the WHOIS and IDENTIFY commands to send the request
2748 to router only if it includes nicknames or other names. If
2749 they include only IDs then check the local cache first before
2750 routing. Affected file is silcd/command.c.
2752 * Added channels topic announcements. Affected file is
2753 silcd/packet_receive.c and silcd/server.c.
2755 * Fixed the silc_server_send_notify_topic_set to really destine
2756 the packet to channel. Affected file silcd/packet_send.c.
2758 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2759 library. Affected file lib/silcclient/client_notify.c.
2761 * Added UMODE announcements. Affected file silcd/server.c.
2763 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Memory leak fixes in:
2767 lib/silcutil/silcsockconn.c
2768 lib/silcske/silcske.c
2769 lib/silcske/groups.c
2771 lib/silccrypt/silcpkcs.c
2772 lib/silccore/silccommand.c
2773 lib/silccore/silcidcache.c
2778 * ROBOdoc documented the lib/silcske/groups.h file and a
2779 bit changed the interface for better.
2781 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2783 * Update the client entry context in the ID cache after
2784 nick change. Affected file lib/silcclient/command.c.
2785 Fixes the CUMODE command when regaining founder privileges,
2786 and a little WHOIS problem.
2788 * Fixed silc_net_gethostbyname to correctly call the
2789 inet_ntop. Affected file lib/silcutil/silcnet.c.
2791 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2793 * Added IPv6 support checking to the configure.in.pre, added
2794 also --enable-ipv6 option to override the check. Affected
2795 file configure.in.pre.
2797 * The silc_thread_create now calls the start function
2798 directly if threads support is not compiled in. Removes
2799 ugly #ifdef's from generic code. Affected files are
2800 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2802 * Added silc_net_gethostby[name/addr]_async to asynchronously
2803 resolve. Affected files are lib/silcutil/silcnet.[ch].
2805 * Added support for rendering IPv6 based server, client and
2806 channel IDs. Affected file lib/silcutil/silcutil.c.
2808 * Added support for creating IPv6 based server IDs. Affected
2809 file is silcd/serverid.c.
2811 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2813 * Added silc_net_gethostby[addr/name] into the
2814 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2815 routines. Added silc_net_is_ip[4/6]. Affected file is
2816 lib/silcutil/unix/silcunixnet.c. All routines that take
2817 address as argument now supports both IPv4 and IPv6 addresses.
2819 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2821 * Fixed LIST command reply sending in server. Affected file
2824 * Server now sends the kicker's client ID in the KICK notify
2825 to the kicked client. Affected file silcd/command.c.
2827 * The client library now parses the kickers client ID and
2828 UI displays it. Affected files lib/silcclient/client_notify.c
2829 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2831 * Made all payload parsing function prototypes consistent.
2832 They all take now const unsigned char * and uint32 pair as
2833 the payload data instead of SilcBuffer. Changes all around
2834 the source tree. Other unsigned char* -> const unsigned char*
2835 changes around the tree as well.
2837 * Optimized SFTP client and server packet sending not to
2838 allocate new buffer for each packet but to recycle the
2839 first allocated buffer. Affected files are
2840 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2842 * Optimized the SFTP client to use SilcList instead of
2843 SilcDList for requests, because it is faster. Affected file
2844 is lib/silcsftp/sftp_client.c.
2846 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2847 into lib/silccore/silcid.[ch].
2849 Renamed silcpayload.[ch] into silcargument.[ch].
2851 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * If client entry is deleted with active key agreement
2854 session, abort the session.
2856 The silc_client_abort_key_agreement now calls the completion
2857 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2859 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2862 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Don't use __restrict in older GCC's. Affected file is
2865 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2867 * silc_net_localhost now attempts to reverse lookup the
2868 IP/hostname. Affected file lib/silcutil/silcnet.c.
2870 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2871 command. It can be used to gain founder privileges at
2872 the same time when joining the channel.
2874 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2875 kicker's client ID as well. Updated protocol specs.
2877 Defined that the server must send SILC_COMMAND_IDENTIFY
2878 command reply with error status to client who sent
2879 private message with invalid client ID.
2881 Updated the protocol specification.
2883 * Added silc_server_send_command_reply to send any
2884 command reply. Affected file silcd/packet_send.[ch].
2886 * Added silc_id_payload_encode_data to encode ID payload
2887 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2889 * The server now send IDENTIFY command reply with error
2890 status if client ID in private message is invalid. Affected
2891 file silcd/packet_receive.c.
2893 * Save the server key file with server's IP address in
2894 the filename instead of hostname. The affected file is
2895 irssi/src/silc/core/client_ops.c.
2897 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2902 * Added libtool support for compiling shared objects in
2903 lib/silcsim. Affected file configure.in.pre and
2904 lib/silcsim/Makefile.am. Original patch by cras.
2906 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Pid file configuration, and server's config file fixes
2909 patch by toma. Updated CREDITS file.
2911 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Fixed silc_client_channel_message to not try to decrypt
2914 the message twice if it resolved the destination client
2915 information. This could cause of dropping one channel
2916 message. Affected file lib/silcclient/client_channel.c.
2918 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2921 lib/silcclient/client.c. This function is used when the SILC
2922 Client is run under some other scheduler, or event loop or
2923 main loop. On GUI applications, for example this may be
2924 desired to used to run the client under the GUI application's
2925 main loop. Typically the GUI application would register an
2926 idle task that calls this function multiple times in a second
2927 to quickly process the SILC specific data.
2929 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2931 * Fixed silc_server_drop() for dropping the supplementary
2932 groups as well, this could cause a security hole on some
2935 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2940 * Write PID file after dropping privileges. Added -F option
2941 to run server on foreground. A patch by debolaz.
2942 Affected files silcd/server.c, silcd/silcd.c.
2944 * Fixed MOTD to return the MOTD file server name. Affected
2945 file silcd/command.c.
2947 * Added INFO command reply handling to the Irssi SILC Client.
2948 Affected file irssi/src/silc/core/client_ops.c.
2950 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Fixed the silc_idcache_list_* routines to really support
2953 the dynamic list. Fixes a crash. Affected file is
2954 lib/silccore/silcidcache.c.
2956 * Fixed the LIST command reply to really call LIST command's
2957 pending callbacks. Affected file silcd/command_reply.c.
2959 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Update conn->local_entry->nickname after giving NICK
2962 command. Affected file lib/silcclient/command.c.
2964 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2966 * Added the [pid] option to the silcd configuration file
2968 Affected files: serverconfig.[ch] and silcd.c
2970 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Save fingerprint in WHOIS command reply in server.
2973 Affected file silcd/command_reply.c.
2975 * Fixed NICK commands pending callback registration.
2976 Affected file lib/silcclient/command.c.
2978 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Use ++server->cmd_ident when sending commands in server,
2981 instead of random number. Affected file silcd/command.c.
2983 * Fixed GETKEY command reply to call actually GETKEY pending
2984 command callbacks. Affected file silcd/command_reply.c.
2986 * A bit stricter check for nicknames. Check for same nickname
2987 in NICK command also. Affected file silcd/command.c.
2989 * Do not call INFO command everytime client ID changes, only
2990 during first connecting. Affected file lib/silcclient/client.c.
2992 * Set the new nickname only after successful command reply for
2993 NICK command is returned by server. Affected file
2994 lib/silcclient/command.c.
2996 * Remove nicknames from nicklist during server_signoff notify.
2997 Should fix /NAMES bit more. The affected file is
2998 irssi/src/silc/core/silc-channels.c.
3000 * Added `fingerprint' field to the SilcIDListData in the
3001 silcd/idlist.h to hold the fingerprint of the client's
3004 Send the fingerprint of the client's public key in WHOIS
3007 Affected files silcd/command.c, and silcd/idlist.[ch].
3009 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3010 create fingerprint from given data.
3012 * Show the fingerprint of the client's public key in WHOIS.
3013 Affected files irssi/src/module-formats.[ch] and
3014 irssi/src/silc/core/client_ops.c.
3016 * Format the multiple same nicknames also during JOIN and
3017 NICK_CHANGE notifys. Affected file is
3018 lib/silcclient/client_notify.c.
3020 * Do not print error on screen for invalid private message
3021 payload since it can come if someone is sending private
3022 messages with wrong key. Affected file
3023 lib/silccore/silcprivate.c.
3025 * Fixed multiple concurrent /PING crash. Affected file
3026 lib/silcclient/command.c.
3028 * Changed the wrong ID encoding. All IP addresses must be
3029 in MSB first order in encoded format. They were encoded
3030 wrong and was in LSB format. Affected files are
3031 silcd/serverid.c, lib/silcutil/silcutil.c.
3033 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3035 * Call the `connect' client operation through the scheduler
3036 in case of error. Affected file lib/silcclient/client.c.
3038 * Call the `failure' client operation even if the error
3039 occurred locally during a protocol. Affected file is
3040 lib/silcclient/protocol.c.
3042 * Added support of sending LIST command to router from normal
3043 server. This way normal server can get list of all channels
3044 in the network too. Fixed the channel list sending in the
3045 server too. Affected files are silcd/command.c, and
3046 silcd/command_reply.[ch].
3048 * Added silc_server_update_channels_by_server and
3049 silc_server_remove_channels_by_server. They are used during
3050 disconnection of primary router and in backup router protocol.
3051 Affected file silcd/server_util.[ch], silcd/server.c and
3052 silcd/server_backup.c.
3054 * Fixed channel adding to global list in IDENTIFY command
3055 reply in server. Affected file silcd/command_reply.c.
3057 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * If the incoming packet type is REKEY or REKEY_DONE process
3060 that packet always synchronously. Fixes yet another MAC
3061 failed error on slow (dialup) connections. Affected file
3062 lib/silcclient/client.c and silcd/server.c.
3064 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Call check_version SKE callback for initiator too. Affected
3067 file lib/silcske/silcske.c.
3069 * Implemented fix for security hole found in the SKE that was
3070 fixed in the specification few days back; the initiator's
3071 public key is now added to the HASH value computation.
3072 Added backwards support for the old way of doing it too, for
3073 old clients and old servers. Affected file is
3074 lib/silcske/silcske.c.
3076 * Enabled mutual authentication by default in SKE. If initiator
3077 is not providing mutual authentication the responder will
3078 force it. This will provide the proof of posession of the
3079 private key for responder. The affected files are
3080 lib/silcclient/protocol.c and silcd/protocol.c.
3082 * Do not cache anymore the server's public key during SKE.
3083 We do mutual authentication so the proof of posession of
3084 private key is done, and if the server is authenticated in
3085 conn auth protocol with public key we must have the public
3086 key already. Affected file silcd/protocol.c.
3088 * Added new global debug variable: silc_debug_hexdump. If
3089 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3090 file lib/silcutil/silclog.[ch].
3092 * Fixed compilation warning due to char * -> const char *.
3093 Affected files lib/silcutil/silcnet.h, and
3094 lib/silccore/silcauth.[ch].
3096 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Fixed CMODE command when new channel key was created. If
3099 the creation failed the old key was removed. Next time giving
3100 same command would crash the server since the old key was
3101 freed already. Affected file silcd/command.c.
3103 * Fixed the silc_server_announce_get_channels to not crash
3104 on reconnect. Affected file silcd/server.c.
3106 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Added silc_log_set_debug_string function to set a regex
3109 string to match for debug output. Only the function names,
3110 or filenames matching the given debug string is actually
3111 printed. This way it is possible to filter out those debug
3112 strings that user is not interested in.
3114 Fixed a bug in silc_string_regexify.
3116 Affected files lib/silcutil/silclog.[ch], and
3117 lib/silcutil/unix/silcunixutil.c.
3119 * Changed the -d options in both server and Irssi SILC client
3120 to take the debug string as argument. Affected files
3121 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3123 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Added silc_hash_babbleprint to create a Bubble Babble
3126 Encoded fingerprint. The encoding is developed by Antti
3127 Huima (draft-huima-babble-01.txt), and it creates human
3128 readable strings out of binary data. Affected file
3129 lib/silccrypt/silchash.[ch].
3131 * Print the babble print now in addition of fingerprint as well
3132 in Irssi SILC client. Affected files are
3133 irssi/src/fe-common/silc/module-formats.[ch],
3134 irssi/src/fe-common/silc/core/client_ops.c.
3136 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Fixed a security problem found in SKE. The initiator's
3139 public key too is now added to the HASH hash value creation
3140 which is signed by the responder to create the SIGN value.
3141 This will prevent anyone in the middle to lie to the responder
3142 about the initiator's public key. If this is done now, the
3143 man in the middle will get caught. Updated the protocol

3182 * Added silc_pkcs_public_key_compare to compare two
3183 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3185 * Check that the client who set the founder mode on the
3186 channel is the same client that is giving the founder
3187 mode to itself. It is done by comparing the saved public
3188 key (it is saved even in the authentication is passphrase).

3197 client library. Affected file lib/silcclient/client.c.
3199 * Fixed the silc_client_packet_parse to not to increase
3200 the packet sequence number if the conn->sock and the
3201 current socket connection is not same. This can happen
3202 for example during key agreement when the conn includes
3203 multiple socket connections (listeners). Affected file
3204 lib/silcclient/client.c.
3206 * The sender of the file transfer request now provides also
3207 the pointer (listener) for the key exchange protocol. If
3208 the listener cannot be created then it sends empty key
3209 agreement and lets the receiver provide the listener.
3211 Added `local_ip' and `local_port' arguments to the
3212 silc_client_file_send. If they are provided they are used,
3213 if not then it will attempt to find local IP address, if

3227 of the client's public key (if the proof of posession of the
3228 corresponding private key is verified by the server).
3229 Updated to the protocol specification.
3231 * Added support of receiving the client's public key's
3232 fingerprint in command reply in client library. Affected
3233 file is lib/silcclient/command_reply.c, and
3234 lib/silcclient/idlist.[ch].

3293 preserve the WHOWAS info for the client. Affected file
3294 silcd/server_util.c.
3296 * Fixed SERVER_SIGNOFF notify handling in the server. The
3297 server is now able to process incoming SERVER_SIGNOFF notify
3298 for a server that it doesn't even know about. It will remove
3299 the clients provided in the notify. Affected file
3300 silcd/packet_receive.c.
3302 * Check for partial packet in data queue after every packet that
3303 was found from the queue. Return and wait for more data if
3304 there is partial data in queue. Affected file is
3305 lib/silccore/silcpacket.c.
3307 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3322 irssi/src/fe-common/silc/module-formats.[ch].
3324 * Wrote a help file for FILE command.
3326 * Added silc_rng_global_get_byte_fast to get not-so-secure
3327 random data as fast as possible. Random data is read from
3328 /dev/urandom if available and from the SILC RNG if not
3329 available. It is used in padding generation. Affected file
3330 lib/silccrypt/silcrng.[ch].
3332 * All packets in client library are now processed synchronously.
3333 Optimized packet processing a lot. Affected file
3334 lib/silcclient/client.c.

3337 now in server, to optimize packet processing. Affected file
3340 * Include files are installed now only in Toolkit distribution
3341 if make install is given. Affected files: all Makefile.am's.
3343 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Assure that silc_client_notify_by_server_resolve does not
3346 resolve the client information multiple times. If it cannot
3347 be found by the first it cannot be found at all. Affected
3348 file lib/silcclient/client_notify.c.
3350 * Fixed WHOWAS command reply calling. Affected file
3351 lib/silcclient/command_reply.c.
3353 * Removed all references to silc_idlist_get_client from the
3354 Irssi SILC client since that call is internal call used by
3355 the library. The Irssi SILC client will use now client
3356 retrieval functions found in silcapi.h.
3358 * Fixed a bug in resolving nickname info before sending
3359 private message. It used freed memory. Affected file
3360 irssi/src/silc/core/silc-servers.c.

3381 * Added silc_net_localip to return local host's IP address.
3382 Affected file lib/silcutil/silcnet.[ch].
3384 * If key exchange or rekey protocol is active for a connection
3385 parse all packets syncronously since there might be packets
3386 in packet queue that we are not able to process without first
3387 processing packets before them. Affected file silcd/server,
3388 lib/silcclient/client.c.
3390 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3391 whether library should continue processing the packet.
3392 Affected file lib/silccore/silcpacket.h.

3438 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3439 is incomplete and is being resolved, it won't be resolved
3442 Make sure also that USERS command reply does not resolve
3443 twice information. Affected file is
3444 lib/silcclient/command_reply.c.
3446 Make sure that silc_client_get_clients_by_list does not
3447 resolve twice same information.
3449 * Check for valid client->id in the silc_server_free_client_data.
3450 Affected file silcd/server.c.
3452 * Fixed /GETKEY nick@server not to crash if the server entry
3453 is not found. Affected file lib/silcclient/command.c.

3465 * Call the silc_server_udpate_servers_by_server in the
3466 primary router that comes back online in the backup resuming
3467 protocol. Otherwise it routes packets wrong. Affected file
3468 silcd/server_util.[ch], silcd/server_backup.c.
3470 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3473 lib/silcutil/silcbuffmt.[ch].
3475 * Redefined the SILC packet header to include the padding
3476 length. Affected file lib/silccore/silcpacket.[ch].
3478 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3479 length for maximum padding up to 128 bytes). Affected
3480 file lib/silccore/silcpacket.h.
3482 * Removed all backwards support for old 0.5.x MAC thingies.
3483 The SILC packet header change makes it impossible to be
3484 backwards compatible.
3486 * Send the ENDING packet with timeout in the backup resuming
3487 protocol. This is to assure that all routers has connected
3488 to the primary router. Affected file silcd/server_backup.c.
3490 * Changed the RNG to take the first IV from random data. It
3491 used to take it from zero actually. Changed the RNG also
3492 to use /dev/urandom during session. /dev/random is used
3493 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3495 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3498 (the packet length) encrypted. Affected files aroung the
3499 code tree, lib/silccore/silcpacket.[ch]. Removed the
3500 SilcPacketCheckDecrypt callback. It is not needed anymore
3501 since the silc_packet_receive_process will determine now
3502 whether the packet is normal or special.
3504 * Implemented the unidirectional MAC keys. Affected files
3505 lib/silcske/silcske.c, silcd/protocol.c and

3513 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Allow backup router to announce servers. All servers
3516 announced by backup router are added to the global list
3517 automatically. Update hte server's socket to our primary
3518 router also when backup router announces a server.
3519 Affected file silcd/packet_receive.c.
3521 * Do not update the client->router in the function
3522 silc_server_udpate_clients_by_server if the client is on
3523 global list. We might fail to find any specific server
3524 for locally connected clients and local cell clients. They
3525 should still use the `from' and not `to' as client->router.
3526 This fixes backup router resuming protocol. Affected file
3527 silcd/server_util.c.
3529 * Decrease channel statistics count only if the channel
3530 deletion worked. Affected files are silcd/server.c and
3531 silcd/server_util.c.
3533 * Added silc_server_update_servers_by_server to update origin
3534 of all server entries. Used during backup router protocol.

3551 to the router it came from. Affected file is
3552 silcd/packet_send.c. Fixed memory leak too.
3554 * Announce informations for incoming router connection, but
3555 only after checking if it is replaced by backup router.
3556 Affected file silcd/packet_receive.c.
3558 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3561 router environment. Affected file silcd/server_backup.c.
3563 * Route packet only to one router in the function
3564 silc_server_packet_send_to_channel. Affected file is
3565 silcd/packet_send.c.
3567 * Fixed silc_server_send_notify_dest to set the broadcast
3568 flag. Fixed the silc_server_send_notify_topic to actually
3569 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3570 Affected file silcd/packet_send.c.
3572 * Changed the SFTP Filesystem interface. Changed the
3573 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3574 the filesystem operation function. The SilcSFTPFilesystem
3575 is now a context that is allocated by all filesystem allocation
3576 functions and it already includes the operations structure
3577 and filesystem specific context. It is given as argument
3578 now to the silc_sftp_server_start. This made the interface
3579 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3580 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3582 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Changed the backup router adding and getting interfaces
3585 in the server. The router that will be replaced by the
3586 specified backup router is now sent as argument. Affected

3608 protocol specification.
3610 * Removed one redundant channel key generation from normal
3611 server during joining procedure. Removed one redundant
3612 channel key sending from server to router during joining
3613 procedure. Affected file silcd/command.c.
3615 * Made minor bugfixes to the backup router resuming protocol.
3616 Affected file silcd/server_backup.c, server.c.

3639 send any data. Affected file lib/silcclient/client.c.
3641 * Implemented the backup router support when the primary router
3642 goes down. The servers and routers can now use the backup
3643 router as new primary router without loosing connectivity.
3645 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3648 in the server to indicate disabled entry. All data read
3649 from the connection will be ignored and no data is sent
3650 for entry that is disabled. Affected files are
3651 silcd/idlist.h, silcd/server.c.
3653 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3667 lib/silcsftp. It includes SFTP client and SFTP server
3670 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Moved lib/silccore/silcprotocol.[ch] to the
3673 lib/silcutil library.
3675 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3676 take variable argument list pointer as argument. Affected
3677 file lib/silcutil/silcbuffmt.[ch].
3679 * Added silc_buffer_set function that is used to set data
3680 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3681 Affected file lib/silcutil/silcbuffer.h.
3683 * Changed various routines in the core library to use the new
3684 silc_buffer_set instead of allocating new buffer only for
3687 * Added 64-bit value formatting and unformatting support to the
3688 silc_buffer_[un]format routines. Affected file is
3689 lib/silcutil/silcbuffmt.[ch].
3691 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3692 to includes/bitmove.h.
3694 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Fixed channel user mode saving in client library. Affected
3697 file lib/silcclient/command[_reply].c.
3699 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Defined the file transfer to the SILC Protocol. Added
3702 new packet type SILC_PACKET_FTP and defined File Transfer
3703 Payload. The mandatory file transfer protocol is SFTP
3704 (SSH File Transfer Protocol). Affected file in addition
3705 of the internet draft is lib/silccore/silcpacket.h.
3707 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3708 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3709 is used as part of backup router protocol when the primary
3710 router of the cell is back online and wishes to resume
3711 the position as primary router.
3713 * Redefined the MAC generation keys in the protocol. The
3714 same key is not used anymore in both direction. Both
3715 direction will now use different keys for sending and
3716 receiving. This fixes a potential security flaw. This
3717 change causes incompatibilities in the protocol.
3719 * Redefined also the MAC computation from the packet.
3720 An packet sequence number is now added to the MAC
3721 computation. This prevents possible replay attacks against
3722 the protocol. This change too causes incompatibilities
3725 Added `sequence' field to the SilcPacketContext to hold
3726 the current sequence number for the packet.
3728 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Added `created' field to the SilcIDListData in the file
3731 silcd/idlist.h to indicate the time when the entry was
3734 * Added `created' field to the SilcChannelEntry too. Affected
3735 file silcd/idlist.h.
3737 * Added `creation_time' aguments to all the announcement functions
3738 in the server. If it is provided then only the entries that
3739 was created after the provided time frame are actually
3740 announced. Affected file silcd/server.[ch].
3742 * The protocol says that the Channel ID's IP address must be
3743 based on the router's IP address. Added check for this in
3744 the silc_server_new_channel when processing incoming New Channel
3745 Payload. Affected file silcd/packet_receive.c.
3747 * Print out the correct version with --version in SILC client.
3748 Affected file irssi/src/silc/core/silc-core.c.
3750 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Fixed WHOWAS command to check for completnes of the client
3753 entry always, not just when the command is coming from client.
3754 Affected file silcd/command.c.
3756 * Added new function silc_server_packet_queue_purge to purge the
3757 outgoing data queue to the network. After the function returns
3758 it is guaranteed that the outgoing packet queue is empty.
3759 Affected file silcd/packet_send.[ch].
3761 * Purge the outgoing packet queue in the rekey protocol's final
3762 callback to assure that all rekey packets go to the network
3763 before quitting the protocol. Affected file silcd/server.c.
3765 * Added silc_client_packet_queue_parse as similar function as
3766 in server to the client library. The affected file is
3767 lib/silcclient/client.c.
3769 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Splitted silcd/server.c and created silcd/server_util.[ch]
3772 for utility functions.
3774 * Added new socket flag SILC_SF_DISABLED to indicate that the
3775 connection is open but nothing can be sent to or received from
3776 the connection. Affected file lib/silcutil/silsockconn.[ch].
3777 The checking for disabled socket is checked in the low level
3778 silc_socket_write and silc_socket_read functions.
3780 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Allow only nicknames and channel names that fits into the
3783 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3785 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * When processing JOIN command reply in server check that if
3788 the channel exists in our global list we'll move it the local
3789 list. Affected file silcd/command_reply.c.
3791 * Fixed the check whether client is joined on the channel already
3792 in JOIN command. Affected file lib/silcclient/command.c.
3794 * Fixed the JOIN command reply to check whether the channel
3795 already exists. Affected file lib/silcclient/command_reply.c.
3797 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Added silc_ske_status_string to map the SKE error numbers
3800 to readable strings. The affected files are
3801 lib/silcske/silcske[_status].[ch].
3803 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Do not show the private channels on the WHOIS channel list
3806 as it is not allowed by the protocol. The affected file is
3809 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Assure that the packet length digged from the actual packet
3812 is something sensible in the silc_packet_decrypt_rest_special
3813 in lib/silccrypt/silcpacket.c.
3815 * Free and NULL the allocated pointer in silc_hmac_alloc if
3816 the HMAC allocation fails. The affected file is
3817 lib/silccrypt/silchmac.c.
3819 * Print the selected security properties to the log files in
3820 the server. Affected file silcd/protocol.c.
3822 * Add SKE's reference counter even if calling the completion
3823 callback manually. Otherwise it goes negative, although it
3824 does not cause any problems. The affected file is
3825 lib/silcske/silcske.c.
3827 * Remove the client entry with short timeout after giving the
3828 KILL command. Affected file lib/silcclient/command.c.
3830 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3831 case all found clients are already disconnected (WHOWAS would
3832 found them) in the server. Affected file silcd/command.c.
3834 * Update the last_receive (time of last data received) to be
3835 updated only when received private or channel message so that
3836 the idle time showed in WHOIS makes more sense.
3838 * Added boolean field `valid' in to the SilcClientEntry in the
3839 client library to indicate whether the entry is valid or not.
3840 This fixes the nickname change bug on channel when changing
3841 the nickname to be same than the old (like nick to Nick) the
3842 nickname formatter doesn't set the new nick anymore to Nick@host.
3843 Affected file lib/silcclient/idlist.[ch].
3845 * Now actually fixed the nickname changing on disconnection.
3846 Added new function silc_change_nick to the Irssi SILC Client.
3847 Affected file irssi/src/silc/core/client_ops.c,
3848 irssi/src/silc/core/silc-nicklist.[ch].
3850 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Check that the public key exists in the GETKEY command before
3853 trying to encode it. Affected file silcd/command.c.
3855 * Print some notifications on received public keys with GETKEY
3856 command in the Irssi SILC Client. Affected files are
3857 irssi/src/fe-common/silc/module-formats.[ch],
3858 irssi/src/silc/core/client_ops.c.
3860 * Use IDENTIFY command to resolve the server information in the
3861 GETKEY command instead of INFO command. Affected file
3862 lib/silcclient/command.c.
3864 * All command reply functions in the client library now calls
3865 the pending command reply callbacks even if an error has
3866 occurred. The server has done this a long time and now it was
3867 time to move the client library to this as well. Now all
3868 errors can be delivered back to the pending command reply
3869 callbacks if necessary. Affected files are
3870 lib/silcclient/command[_reply].[ch].
3872 * Change the nickname on disconnection back to the username
3873 because in reconnect the server will enforce it to it anyway.
3874 Affected file irssi/src/silc/core/silc-servers.c.
3876 * Fixed a config file parsing bug in the Irssi SILC client.
3877 Affected file irssi/src/silc/core/clientconfig.c.
3879 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * When printing the channel mode on JOIN, verify that the
3882 channel key and channel's HMAC are valid. Affected file
3883 irssi/src/silc/core/client_ops.c.
3885 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3888 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3889 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3891 * Removed channel key rekey task deleting from the function
3892 silc_server_save_channel_key. Affected file silcd/server.c.
3893 Added explicit timeout task context instead that is used to
3894 delete the task if we are registering a new task before the
3895 new task has elapsed.
3897 * When channel key rekey occurs the client library now saves
3898 the old channel key for a short period of time (10 seconds) and
3899 is able to use it in case some is still sending channel
3900 messages encrypted with the old key after the rekey. Affected
3901 file lib/silcclient/[idlist.h|client_channel.c].
3903 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Added check to the silc_server_new_id_real to not accept
3906 new ID if it is the sender's own ID. Affected file is
3907 silcd/packet_receive.c.
3909 * Assure that we do not announce ourself or the one we've
3910 sending our announcements when we're router and are announcing
3911 servers to our primary router. Affected file silcd/server.c.
3913 * Fixed silc_server_command_identify_check_client to assemble
3914 correct WHOIS packet. It send corrupted WHOIS packet and
3915 caused problem with router to router connections. Affected
3916 file silcd/command.c.
3918 Fixed also silc_server_command_whois_check the same way
3919 as for the IDENTIFY command.
3921 * Added new SilcIDListStatus to the server in the SilcIDListData
3922 structure. The status now includes the current status of
3923 the entry (like registered, resolved etc.). Affected file
3924 silcd/idlist.[ch]. Defined a bunch of different status types
3925 as well. This replaced the old boolean registered field as well.
3927 Added resolve_cmd_ident field to the SilcClientEntry structure
3928 too so that if the entry is for example being resolved so
3929 another command may attach to the same pending command reply
3930 without requiring to resolve the same entry again. This concept
3931 should optimize the WHOIS and the IDENTIFY resolving under
3932 heavy load by taking away unnecessary resolving for entries
3933 that are being resolved already.
3935 Added support for adding multiple pending commands for one
3936 command idenfier. Affected file silcd/command[_reply].[ch].
3938 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3939 before deleting the data. Otherwise the hash table will have
3940 freed data in comparison functions. Affected file is
3941 silcd/command_reply.c.
3943 * Fixed silc_idlist_replace_client_id to add the new entry to
3944 the cache with NULL nickname. Otherwise there will be invalid
3945 memory as the nickname after the nickname is freed. Affected
3946 file silcd/packet_receive.c.
3948 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3949 saved into wrong slots because the previous number of entries
3950 was not taken into account. Affected file silcd/idlist.c.
3951 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3953 * If we are router and we receive JOIN notify to a channel that
3954 does not have any users then notified client is marked as the
3955 channel founder, as it is it. The affected file is
3956 silcd/packet_receive.c
3958 * Added to the extended hash table API's table_del_*ext functions
3959 the destructor as argument too, so that the caller can decide
3960 which destructor to use or whether to use destructor at all.
3961 Affected file lib/silcutil/silchashtable.[ch].
3963 * Fixed ID Cache purging. It actually deleted the entries from
3964 the hash table after the data was freed. The hash table ended
3965 up comparing freed memory. The affected file is
3966 lib/silccore/silcidcache.c.
3968 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3970 * Fixed Irssi SILC client's KILL command's HELP syntax.
3972 * The USERS command now resolves the detailed user information
3973 if the userinfo field is missing. Affected file is
3974 lib/silcclient/command_reply.c.
3976 * Do not print error in silc_file_read if the read file does
3977 not exist. Just silently return NULL. Affected file is
3978 lib/silcutil/silcutil.c.
3980 * Fixed the silc_log_output to not wine about NULL filename
3981 and to not create some bogus " " filename. Affected file is
3982 lib/silcutil/silclog.c.
3984 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Fixed various printing bugs on the user interface in the
3987 Irssi SILC Client. Minor changes that were forgotten from
3990 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Fixed the configure.in.pre and the compilation and distribution
3993 environment to support the new autoconf 2.52. That version is
3994 now required to compile the CVS trunk.
3996 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3999 to generally parse user@fqdn format strings. Affected file
4000 lib/silcutil/silcutil.c.
4002 * Added nickname_format and nickname_force_format fields to the
4003 SilcClientParams structure. The first one defines the format
4004 for the nicknames that the library will enforce if the receives
4005 multiple same nicknames. The second one is boolean value and
4006 can be used to force the library to always enforce the format
4007 to the nicknames regardles whether there are multiple nicknames
4008 or not. This configurable formatting was employed to flexibly
4009 support accessing multiple nicknames from the user interface.
4010 The userinterface can now set the nicknames to what ever format
4011 they prefer. Affected file lib/silcclient/silcapi.h.
4013 Added function silc_client_nickname_format to the file
4014 lib/silcclient/idlist.c. It performs the nickname formatting.
4016 Added new field `hostname´ to the SilcClientEntry context.
4017 It holds the hostname of the client. Affected file is
4018 lib/silcclient/idlist.h.
4020 * Irssi SILC Client sets the nicknames in nick@hostn format.
4021 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4022 irssi/src/silc/core/silc-core.c.
4024 The WHOIS printing now also shows both the real nickname and
4025 the formatted nickname so that user knows how to access the
4026 user if there are multiple same nicknames cached. Affected
4027 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4028 printing formatting too to take the hostname now as a separate
4029 argument. The Affected file is
4030 irssi/src/fe-common/silc/modules-formats.[ch].
4032 * Changed the silc_client_get_clients_local to accept the formatted
4033 nickname as argument. It accepts the real nickname too but the
4034 formatted nickname can be used to find the true entry from
4035 multiple entries. Affected file lib/silcclient/silcapi.h and
4036 lib/silcclient/idlist.c.
4038 * Added nickname_format_parse field to the SilcClientParams.
4039 It is a callback function provided by the application to parse
4040 the nickname out of the formatted nickname string. The library
4041 calls it to get the nickname from the formatted string. Since
4042 the application generally knows better the format of the nickname
4043 string it parses it instead of the library, even though library
4044 encodes the formatted string. If the callback function is not
4045 provided then the library will use the string as is. The
4046 affected file is lib/silcclient/silcapi.h.
4048 * All the nickname strings passed to the client library in
4049 commands are now expected to be formatted nickname strings.
4050 If the command does not support the formatted nickname string
4051 it will assume that the sent string is the actual nickname.
4052 Affected file lib/silcclient/command.c.
4054 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4056 * Added public key authentication support to OPER and SILCOPER
4057 commands in the client library. Affected file is
4058 lib/silcclient/command.c.
4060 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Changed the get_auth_methdod client operation to be asynchronous.
4063 It can be async if the application resolves the authentication
4064 method from the server during the negotiation. Added new
4065 SilcGetAuthMeth completion callback that the application will
4066 call after resolving the authentication method.
4068 Added function silc_client_request_authentication_method that
4069 the application can use to resolve the authentication method
4070 from the server. Added also SilcConnectionAuthRequest callback
4071 that the library will call after the server has replied. The
4072 application can call this function if it does not know the
4073 current authentication method.
4075 Affected files are lib/silcclient/client.c and
4076 lib/silcclient/silcapi.h.
4078 * The Irssi SILC client now automatically resolves the authentication
4079 method incase any configuration information is not present (and
4080 currently there never is). The affected file is
4081 irssi/src/silc/core/client_ops.c.
4083 * Fixed public key authentication from the client library.
4084 Affected file lib/silcclient/protocol.c. Changed also the
4085 protocol specification about the public key authentication in
4086 the connection authentication protocol. The actual data to be
4087 signed is now computed with a hash function before signing.
4089 * Fixed the public key authentication from the server as well.
4090 Affected file silcd/protocol.c.
4092 * Removed the mlock()'s from the memory allocation routines.
4093 Affected file lib/silcutil/silcmemory.c. The ./configure does
4094 not check anymore for the mlock(). Affected file is
4097 * Fixed USERS command in server to allow the execution of the
4098 command for private and secret channels if the client sending
4099 the command is on the channel. Affected file silcd/command.c.
4101 * Fixed silc_client_get_clients_local to return the clients
4102 count correctly. It could return wrong value. Affected file
4103 lib/silcclient/idlist.c.
4105 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4107 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4108 types. The assembler optimizations seemed not to like 64-bit
4109 data types. The assmebler optimizations thus are now enabled
4110 also for BSD systems as opposed to only enable them for Linux.
4112 * Do not check for threads at all on BSD systems. Affected
4113 file configure.in.pre.
4115 * Removed -n and -h options from the Irssi SILC Client since
4116 they are not used in silc.
4118 * Fixed the prime generation to assure that the first digit
4119 of the generated random number is not zero since our conversion
4120 routines does not like number strings that starts with zero
4121 digit. If zero digit is seen the random number is regenerated.
4122 This caused some corrupted RSA keys when the zero first digit
4123 was met. Affected file lib/silcmath/silcprimegen.c.
4125 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * Fixed WIN32 configuration in the ./configure script.
4128 Fixed to include xti.h on environments that has it.
4129 Patches by Carsten Ilchmann and andrew.
4131 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4133 * Changed the silc_id_create_client_id to be collision
4134 resistant. It is now assured that there cannot be created
4135 two same client ID's. I suspect that some weird bugs in
4136 the server were actually caused by duplicate Client IDs.
4137 Affected file silcd/serverid.[ch]. A router receiving
4138 new ID now also assures and informs the sending server
4139 if the ID caused collision.
4141 * Changed the silc_id_create_channel_id to also assure that
4142 there are no collisions.
4144 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4146 * Statement about ignoring the Mutual Authentication flag when
4147 performing rekey with PFS was a bit misleading. It is ignored
4148 if it was set in the initial negotiation, it cannot be even
4149 set in the rekey. Fixed in the ke-auth draft. Started the
4150 new versions of the protocol drafts in the doc/.
4152 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Fixed a bug in silc_client_command_identify_save when saving
4155 new channel information. The channel name was no duplicated
4156 and caused crash on exit. Affected file is
4157 lib/silcclient/command_reply.c.
4159 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4161 * Fixed the getkey command handling in the server. Send just
4162 empty OK reply to the sender if the key could not be fetched
4163 (but everything else was ok, like the key just was not available).
4164 Changed the public key parameter to optional in the protocol
4165 specs so that empty OK reply can be sent. Affected file
4168 Added a message to Irssi SILC client to tell to user if the
4169 server did not return a public key.
4171 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * Fixed a channel key regeneration bug. It registered new
4174 timeout tasks exponentially until all system resources were
4175 used. Affected file silcd/server.c.
4177 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4179 * Added the SILC Document generator to the scripts/silcdoc.
4180 It can be used to generate the Toolkit Reference Manual out
4181 of the source tree. Internally it will also use the RoboDoc
4182 generator now imported in util/robodoc.
4184 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4186 * Added couple of return's in rekey protocol if error orccurred
4187 during the protocol. The execution must be terminated.
4188 Affected file silcd/protocol.c. Also, terminate the protocol
4189 always with timeout.
4191 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * The client's Client ID was created initally from the wrong
4194 nickname (it could have been in format nick@host) in the
4195 silc_server_new_client. Affected file silcd/packet_receive.c
4197 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4199 * Added some SILC_LOG_ERROR's to various error conditions
4200 if client could not be added to ID cache. Affected files
4201 silcd/packet_receive.c and silcd/server.c.
4203 * When client's sock->user_data is freed, NULL also the
4204 client->router and client->connection pointers. Added check
4205 for these pointers being NULL to various places around the
4206 code. Affected file silcd/server.c.
4208 * Added client->data.registered == TRUE checks to various
4209 places around the code to assure that unregistered client's
4210 are not handled when it is not allowed. Affected file
4213 * Added `bool registered' fields to all
4214 silc_idlist_[server|client]_get_* routines to indicate whether
4215 the fetched client needs to be registered or not. Affected
4216 file silcd/idlist.[ch].
4218 * Add your own entry as registered to the ID cache in the
4219 server. Affected file server.c.
4221 * Fixed a bug in silc_server_new_server. The SilcServer was
4222 set as the new server's context instead of SilcServerEntry.
4223 This naturally caused some weird bugs.
4225 * Added "updated" field the SilcChannelEntry which indicates
4226 the time since the channel entry was last accessed. This
4227 can be used to determine whether it is necessary to
4228 announce the channel after backup resuming protocol.
4229 Affected files silcd/idlist.[ch].
4231 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4233 * Do not delete the channel rekey task when adding it
4234 for in silc_server_create_channel_key.
4236 * Changed the silc_server_create_channel_key to return
4237 TRUE or FALSE to indicate the success of the channel key
4240 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4242 * Fixed MSVC++ project files and added missing files to

4245 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * Do not add TCP_NODELAY flag if the operating system
4248 does not have it defined. Affected files are
4249 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4251 * Fixed buffer overflow from Irssi SILC Client. Affected
4252 file irssi/src/fe-common/core/themes.c.
4254 * Fixed double free in client library in the file
4255 lib/silcclient/client.c when disconnecting from server.
4257 * Applied double free patch from cras to Irssi SILC client.
4258 Affected files irssi/src/core/[modules/expandos].c
4260 * Fixed the disconnection handling to Irssi SILC Client.
4261 The application must call silc_client_close_connection
4262 in ops->connect client operation in case of failure of
4263 the connection. Affected file is
4264 irssi/src/silc/core/client_ops.c.
4266 * Do not set sock->protocol to NULL in the function
4267 silc_client_close_connection after executing the protocol's
4268 final callback since the sock might not be valid anymore.
4269 Affected file lib/silcclient/client.c.
4271 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4273 * Do not enable SILC_THREADS if the linking with libpthread
4274 did not happen. Affected file configure.in.pre.
4276 * Added notion to protocol specification that server must
4277 verify the sent authentication payload with CMODE when
4278 setting the channel founder key. Implemented it to the
4279 server. Affected file silcd/command.c.
4281 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4283 * Added _EXTRA_DIST SILC distribution variable to the
4284 distributions file. It is used to conditionally add extra
4285 files or directories to the specific distribution. Affected
4286 files ./prepare, Makefile.am.pre and distributions.
4288 Removed the `_' from the start of the distribution names.
4291 * Added README.WIN32 for instructions to compile the Toolkit
4294 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4296 * Fixed a double free in disconnection in the server. Affected
4297 file is silcd/server.c.
4299 * Fixed the lib/silcske/groups.c to work now also with GMP
4300 MP library. The string conversion did not work when using
4301 specific base and the base is indicated in the string as well.
4303 * Created win32/ directory which now includes MSVC++ specific
4304 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4305 It will appear only in the toolkit distribution
4307 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * Changed the key material distribution function in case when
4310 the hash output is too short. The data is now concatenated
4311 a bit differently than it used to. Made the change to the
4312 SKE protocol specification.
4314 * Added better GMP detection to configure.in.pre. A patch
4317 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4319 * Fixed a minor bug in SKE that might cause some problem on
4320 some platforms. Affected file lib/silcske/silcske.c.
4322 * Added the cookie checking for initiator in the SKE. It checks
4323 that the responder returns the sent cookie unmodified. The
4324 affected file is lib/silcske/silcske.c. Added new SKE
4325 error type INVALID_COOKIE that can be sent during the
4326 negotiation. Fixed some memory leaks as well.
4328 * Added the "invalid cookie" error message to Irssi SILC client's
4331 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4333 * Added `task_max' field to the SilcClientParams to indicate
4334 the maximum tasks the scheduler can handle. If set to zero,
4335 default values are used. Affected file lib/silcclient/silcapi.h.
4337 * Fixed memory leaks in silc_client_close_connection. Affected
4338 file lib/silcclient/client.c.
4340 * Added silc_client_del_client_entry to client library to free
4341 all memory of given client entry. Affected file is
4342 lib/silcclient/idlist.[ch].
4344 * Added new functions silc_client_del_channel and
4345 silc_client_del_server to delete channel and server entries.
4346 Affected file lib/silcclient/[silcapi.h/idlist.c].
4348 * Removed silc_client_del_client_by_id from silcapi.h.
4350 * Fixed the INFO command to return the server's own info
4351 correctly when querying by Server ID. Affected file is
4354 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Removed the non-blocking settings in WIN32 code in the
4357 silc_sock_[read/write] and added SleepEx instead. Affected
4358 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4359 of input data is now checked with FIONREAD and ioctlsocket.
4361 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4363 * Call silc_schedule_task_del_by_context in the
4364 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4365 Affected file lib/silccore/silcprotocol.c.
4367 * Call silc_protocol_cancel for active protocols in the
4368 silc_server_close_connection if the funtion
4369 silc_server_free_sock_user_data has not been called.
4370 Affected file silcd/server.c.
4372 * Generic tasks cannot be deleted using the del_by_fd
4373 task deleting function since generic tasks does not match
4374 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4376 * Added a notion to SILCOPER help file that the SILCOPER works
4377 only on router server, not on normal server.
4379 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4381 * Added for WIN32 support for the new scheduler as well.
4382 Affected file lib/silcutil/win32/silcwin32schedule.c.
4384 * Fixed the SHA1 implementation to work on various platforms.
4386 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4388 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4389 API. It is part of the scheduler now. Everything else is
4390 as previously but some functions has changed their names.
4391 Checkout the lib/silcutil/silcschedule.h for the interface.
4392 Updated all applications to use the new interface. Affected
4393 files are lib/silcutil/silcschedule.[ch].
4395 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4397 * Found a bug in the SKE implementation. The HASH value,
4398 specified by the protocol, was not computed correctly. The
4399 public key of the responder was not added to the computation
4400 even though it is mandatory. Affected file lib/silcske/silcske.c.
4401 This unfortunately causes incompatibilities with older
4402 clients and servers.
4404 * Added WIN32 specific network init and uninit functions:
4405 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4406 the Winsock2. Affected file lib/silcutil/silcnet.h and
4407 lib/silcutil/win32/silcwin32net.c.
4409 * Set the socket always to nonblocking mode on WIN32 after
4410 reading data or writing data. Affected file is
4411 lib/silcutil/win32/silcwin32sockconn.c.
4413 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4415 * Fixed various compilation problems under WIN32. Affected
4416 files lib/silcutil/win32/silcwin32thread.c and
4417 lib/silcutil/win32/silcwin32schedule.c.
4419 * Removed all _internal.h #includes from public header
4420 files. Internal headers must never be included from
4423 Removed also the lib/silcske/payload_internal.h file.
4425 * All include files that may be needed (public and some others
4426 included by the public headers) by application developers are
4427 now copied to the ./includes directory. It does not copy any
4428 internal headers. Affected file Makefile.defines.pre and all
4429 Makefile.am's under lib/ and subdirs.
4431 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Do not change the ~/.silc directory's permissions automatically.
4434 Affected file irssi/src/silc/core/clientutil.c.
4436 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4438 * Do not cancel the protocol in silc_server_close_connection
4439 it might cause recursion. Now cancelled in the function
4440 silc_server_free_sock_user_data. Affected file silcd/server.c.
4442 * Fixed the silc_server_remove_clients_by_server to regenerate
4443 the channel keys correctly finally. Added also new function
4444 silc_server_remove_clients_channels to actually do it.
4445 Affected file silcd/server.c.
4447 * Fixed the silc_server_new_channel to not crash by giving
4448 wrong router to the new channel. Affected file is
4449 silcd/packet_receive.c.
4451 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4453 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4454 which is given as argument to the silc_client_alloc now.
4455 It can be used to configure the client and set various parameters
4456 that affect the function of the client.
4458 * The USERS command in server did not check whether the channel
4459 is private or secret. Affected file silcd/command.c.
4461 * Added new argument to the USERS command in protocol specification.
4462 The USERS command now can take the channel name as argument
4463 as well. Added support for this in client and server and
4464 updated the protocol specs.
4466 * Completed the GETKEY command in client. It can be now used
4467 to fetch also servers public key not only some clients.
4468 Affected files lib/silcclient/command[_reply].c.
4470 * Added silc_client_get_server to return server entry by the
4471 server name. Affected files lib/silcclient/silcapi.h and
4474 * Redefined the IDENTIFY command in protocol specification to be
4475 more generic. It now can be used to query information about
4476 any entity in the SILC Network, including clients, servers and
4477 channels. The query may be based either the entity's name
4478 or the ID. Added support for this in both client and server.
4480 Affected files silcd/command.c and lib/silcclient/command.c
4481 and command_reply.c.
4483 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4484 the _from_client and _from_server functions. Affected file
4487 * Added silc_client_get_channel_by_id_resolve to the file
4488 lib/silcclient/silcapi.h to resolve channel information by
4489 its ID. Added also silc_client_get_channel_by_id that
4490 does not resolve it from the server.
4492 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4494 * Added SilcServerEntry context into the client library
4495 to represent one server. The INFO command now allocates
4496 these to save the resolved server info. For now on the
4497 client library will also keep information about servers,
4498 connected and resolved with INFO.
4500 The INFO command now allocates the SilcServerEntry context
4501 and saves the server info there. The COMMAND_REPLY in
4502 the INFO now returns the parameters to application in
4503 same order as defined in the protocol specification.
4505 The entries are cached in the client->server_cache.
4507 * The INFO command is now issued after received the Client ID
4508 from the server. Affected file lib/silcclient/client.c.
4510 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4511 to the application as the mode changer might be server.
4512 It is guaranteed that NULL is not returned anymore to the
4513 application. Affected file lib/silcclient/client_notify.c.
4515 The ID Type is now also passed to the application so that
4516 it can check whether the returned entry is SilcClientEntry
4519 Added new function silc_client_get_server_by_id to return
4520 the server entry by ID. Affected files are the
4521 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4523 * Do not create the channel in the Irssi SILC Client when issuing
4524 the JOIN command but when received the sucessful JOIN command
4525 reply. Otherwise the channel might get created even though we
4526 could not join it. The Affected file is
4527 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4529 * Fixed a channel joining bug in router. The router must also
4530 check the channel modes, invite and ban lists etc. when serving
4531 the JOIN command sent by normal server. Affected file is
4532 silcd/command.c. The router now resolves the client's
4533 information from the server who sent the JOIN command if it
4534 does not know it, and processes the JOIN command only after
4537 * Changed the SilcCommandCb to take new argument; void *context2.
4538 Affected file lib/silccore/silccommand.h
4540 The second argument in the command callbacks in the server now
4541 includes the SilcServerCommandReplyContext if the command was
4542 called as pending command callback from the command reply.
4543 Otherwise it is NULL. When called as pending the status of the
4544 command reply will be checked and if it was erronous the
4545 error will be sent to the original sender of the command.
4546 This way the client always receives the error messages even
4547 though the server was actually the one who received the error
4548 when it resent the command to router, for example. Affected
4549 files silcd/command[_reply].[ch].
4551 * Fixed sending WHOWAS command's error message to client if
4552 the requested client could not be found. It was missing.
4555 * Changed the CMODE and CUMODE commands reply arguments in the
4556 protocol specification. The Channel ID is now sent in both
4557 of the commands to identify the channel. Implemented this
4558 new feature to the client and server. Affected files
4559 lib/silcclient/command_reply.c and silcd/command.c.
4561 * Made better checks for invite and ban lists in the JOIN
4562 command in server. Affected file silcd/command.c.
4564 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4566 * The server now performs the incoming host IP/DNS lookup
4567 using the silc_socket_host_lookup and thus does not block
4568 the server anymore. Affected file silcd/server.c.
4570 * Completed the multi-thread support for SILC Scheduler in
4571 the lib/silcutil/silcschedule.c.
4573 * Fixed the configure.in.pre to detect the pthread correctly
4576 * Fixed a deadlock in silc_task_queue_wakeup in the file
4577 lib/silcutil/silctask.c.
4579 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4581 * Added new function silc_schedule_wakeup that is used in
4582 multi-threaded environment to wakeup the main thread's
4583 schduler. It needs to be used when a thread adds a new task
4584 or removes a task from task queues. After waking up, the
4585 scheduler will detect the task queue changes. If threads
4586 support is not compiled in this function has no effect.
4587 Implemented the wakeup mechanism to both Unix and WIN32
4588 systems. Affected files are lib/silcutil/silcschedule.[ch],
4589 lib/silcutil/unix/silcunixschedule.c and the
4590 lib/silcutil/win32/silcwin32schedule.c.
4592 * Added new function silc_task_queue_wakeup to wakeup the
4593 scheduler by the specified task queue. Affected file
4594 lib/silcutil/silctask.[ch].
4596 * The silc_socket_host_lookup_start now wakes up the scheduler
4597 after adding the timeout task. Affected file is
4598 lib/silcutil/silcsockconn.c.
4600 * The silc_socket_host_lookup is synchronous now if the threads
4601 support is not compiled in. However, the callback is still
4602 called asyncronously through the scheduler, anyway. Affected
4603 file lib/silcutil/silcsockconn.c.
4605 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4607 * Added new function silc_socket_host_lookup to perform
4608 asynchronous IP and FQDN lookups for the socket connection.
4609 Affected files lib/silcutil/silcsockconn.[ch].
4611 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4613 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4614 that may or may not compile the mutex support in.
4616 Changed the silc_mutex_alloc interface. It allocates the
4617 mutex now to the sent pointer and returns TRUE or FALSE.
4619 Affected file lib/silcutil/silcmutex.h.
4621 * Wrote the SILC Task Queue interface to support multi-threads.
4622 Affected file lib/silcutil/silctask.[ch].
4624 * Wrote the SILC Scheduler to support multi-threads. Affected
4625 file lib/silcutil/silcschedule.c.
4627 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4629 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4630 in lib/silcutil/win32/.
4632 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4634 * Defined SILC Mutex API and SILC Thread API and implemented
4635 them for Unix. Affected files are
4636 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4637 lib/silcutil/unix/silcunixmutex.c and
4638 lib/silcutil/unix/silcunixthread.c.
4640 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4642 * Fixed the silc_server_remove_clients_by_server's channel
4643 key re-generation. The hash table handling was incorrect
4644 and would not work with many channels. Affected file is
4647 * Fixed some memory leaks around the server code.
4649 * Rewrote the silc_server_get_users_on_channel to support IPv6
4650 based Client ID's. Affected file silcd/server.c.
4652 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4653 specification. However, a separate document must be written
4654 to define the detailed signing procedure and the payload
4655 associated with the flag. Defined the flag to the
4656 lib/silccore/silcchannel.h as well.
4658 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4660 * Changed the dynamic tables to static size tables in the
4661 lib/silccrypt/silchmac.c.
4663 * Removed GCC dependencies from the code. A patch by cras.
4665 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4667 * Do not show the error "Error receiving packet bla bla"
4668 in server if it really was not an error (-2 means that reading
4669 is pending). Affected file silcd/server.c.
4671 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Fixed a possible crash in silc_server_remove_clients_by_server
4674 in silcd/server.c. Fixed there also some memory leaks.
4676 * Fixed the silc_idlist_replace_client_id. It could replace
4677 wrong key in the hash table. Affected file silcd/idlist.c.
4679 * Do not check whether there are global users on the channel
4680 if the channel->global_users is FALSE. Affected functions
4681 silc_server_remove_from_one_channel and
4682 silc_server_remove_from_channels in silcd/server.c. Also,
4683 do not check if the removed client is local as we can be
4684 sure that global client was not removed from the channel
4685 and checking for global users is not needed.
4687 * The silc_server_remove_clients_by_server now re-generates
4688 the channel keys correctly for those channels that had
4689 clients removed from them. Affected file silcd/server.c.
4691 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4693 * Found the reason of random crashes in the server. We weren't
4694 ignoring the SIGPIPE signal (which can be sent in write())
4695 and it crashed the server. Affected file silcd/silcd.c.
4697 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * Assure that sock->user_data is not NULL in the function
4700 silc_server_packet_send in silcd/packet_send.c.
4702 * Disconnect the remote connection if it could not be added
4703 to any ID lists in the server. The affected file is
4706 * Check in silc_server_packet_send[_real/dest] that the
4707 socket is not disconnecting and ignore the data if it is.
4708 Affected file silcd/packet_send.c.
4710 * Define inline to __inline on native WIN32 compilation.
4711 Affected file includes/silcwin32.h.
4713 * Added some explicit type casts for inline code since MSVC
4714 require them. Affected files lib/silcutil/silcbuffer.h,
4715 lib/trq/silcdlist.h and lib/trq/silclist.h.
4717 * Print warning in log files from now on if the packet
4718 decryption fails. Affected file silcd/server.c.
4720 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4722 * Changed the `say' client operation's interface to accept
4723 new `type' argument to indicate the type of the message sent
4724 by the library. The application may filter the library's
4725 messages according the type. The affected file is the
4726 lib/silcclient/silcapi.h.
4728 * Added two new functions to lib/silcclient/silcapi.h:
4729 silc_client_del_client and silc_client_del_client_by_id.
4730 Affected file lib/silcclient/idlist.c.
4732 * Moved the clientincludes.h from includes/ to silc/ and
4733 serverincludes.h from includes/ to silcd/.
4735 * The modes for the CMODE and CUMODE are now passed as
4736 uint32 for application with COMMAND_REPLY. The affected
4737 file is lib/silcclient/command_reply.c.
4739 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4741 * /WHOIS without arguments shows client's own information.
4742 Affected file lib/silcclient/command.c.
4744 * Changed PING to not accept any arguments. The specs
4745 says that client can ping only the connected server so
4746 requiring an argument is not needed. Affected file is
4747 lib/silcclient/command.c.
4749 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4751 * Fixed a fatal bug in private message sending and reception
4752 encryption and decryption when using private message keys.
4753 The implementation was incorrect and did not follow the
4754 specification. It causd that some of the message were
4755 lost since it did not use the sending and receiving keys
4756 as the protocol suggests. This has been fixed and will cause
4757 incompatibilities with older clients when sending private
4758 message encrypted with private message keys. Affected files
4759 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4760 and various other in Irssi SILC Client.
4762 Added `responder' boolean argument to the functions
4763 silc_client_add_private_message_key[_ske] to indicate when
4764 the key is added as responder or initiator of the key
4767 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4769 * Removed the silc_ske_check_version function and created
4770 a SilcSKECheckVersion callback. Added also a function
4771 silc_ske_set_callbacks that is now used to set all SKE
4772 callbacks. The callback functions are not given to
4773 the SKE functions anymore, but this function is used to
4776 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4778 * Added `silc_version' argument to the silc_client_alloc
4779 to define the version of the application for the library.
4780 The library will use the version string to compare it
4781 against the remote host's (usually a server) version
4782 string. Affected file lib/silcclient/silcapi.h
4784 * Added the KE protocol context to Key Agreement context
4785 in client library so that we can abort the SKE if it
4786 is in process when we get timeout. Affected file is
4787 lib/silcclient/client_keyagr.c.
4789 * Do not resolve the client ID forever if it returns in the
4790 first time that such client does not exist. This was done
4791 for example with private message. Affected file is
4792 lib/silcclient/client_prvmsg.c.
4794 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4796 * Do not add regex.h for WIN32. The affected file
4797 includes/silcincludes.h.
4799 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4800 not work yet 100%. It generates the DLL's automatically
4801 when compiling with --with-win32 under cygwin.
4803 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4805 * lib/contrib/regex.c is not compiled on WIN32.
4807 * Added silc_net_get_socket_opt function to the
4808 lib/silcutil/silcnet.h.
4810 * Added includes/silcwin32.h for WIN32 specific includes
4813 * Do not use ptime structure or any of the posix process
4814 functions on WIN32 in lib/silccrypt/silrng.c.
4816 * Added silc_gettimeofday to provide generic function
4817 for struct timeval on all platforms. Added the function
4818 to lib/silcutil/silcutil.h.
4820 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4823 library as they clearly belong there. As a plus side we
4824 can make the actual socket connection routines platform
4827 Added also new generic function silc_socket_read and
4828 silc_socket_write (that used to be silc_packet_[read/write].
4829 The implementation of these are platform specific.
4831 * Added WIN32 specific routines of silc_socket_[read/write]
4832 to lib/silcutil/win32/silcwin32sockconn.c.
4834 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4836 * Added preliminary support for native WIN32 compilation under
4837 cygwin (using the -mno-cygwin option for GCC) to the
4838 ./configure.in.pre. The --with-win32 now prepares the
4839 compilation for native WIN32.
4841 * Rewrote the SILC Scheduler interface in the file
4842 lib/silcutil/silcschedule.h. The scheduler is now context
4843 based and does not have anymore any global static scheduler.
4844 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4845 and created lib/silcutil/win32 directory for WIN32 based
4848 * Added Unix specific network routines to the
4849 lib/silcutil/unix/silcunixnet.c and the old
4850 lib/silcutil/silcnet.c includes now only generic routines.
4852 Added WIN32 specific network routines to the
4853 lib/silcutil/win32/silcwin32net.c.
4855 * Added Unix specific utility functions from the
4856 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4858 * Added WIN32 SILC Scheduler to the file
4859 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4862 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4864 * Do not handle JOIN notify in the server if the target client
4865 is not registered (idata->registered == FALSE). The affected
4866 file is silcd/packet_receive.c.
4868 * Update the nickrec->founder in event_cumode in the Irssi SILC
4869 client. Affected file irssi/src/silc/core/silc-channels.c.
4871 * Fixed the CUMODE_CHANGE notify handling in the server when
4872 server and router are announcing their clients on channels.
4873 Now the mode changes are saved and notified correctly. The
4874 affected file is /silcd/packet_receive.c.
4876 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4877 They really did not replace the cache entry in the ID Cache.
4878 Now they do that. Affected file silcd/idlist.c.
4880 * Fixed the KICK notify handling in the Irssi SILC client to
4881 update the channel records so that the kicked client does not
4882 appear to be on the channel. The affected file is
4883 irssi/src/silc/core/silc-channels.c.
4885 * Always update the conn->current_channel when executing command
4886 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4888 * Fixed the KILL notify handling in Irssi SILC client to remove
4889 the killed client on all channels.
4891 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Fixed the silc_parse_command_line to remove extra spaces
4894 from the start and end of the arguments. Affected file is
4895 lib/silcutil/silcutil.c.
4897 * Cancel and free any active protocol in the function
4898 silc_server_close_connection. Affected file silcd/server.c.
4900 * Cancel and free any active protocol in the function
4901 silc_client_close_connction. Affected file is
4902 lib/silcclient/client.c.
4904 * Do not execute the KILL command for clients that are in
4905 history (ie. they are not in the network). Affected file is
4908 * Fixed KILL notify handling, client does not crash anymore.
4909 Affected file irssi/src/silc/core/silc-channels.c.
4911 * Reduced the default packet buffer size from 2048 to 1024 in
4912 lib/silccore/silcpacket.c.
4914 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4915 counter to the SKE context that is incresed when the SKE library
4916 performs async operation outside the library. If the outside
4917 process frees the SKE context and FREED status will be set
4918 and the library will detect after the sync operation that the
4919 libary is freed. The affected files are
4920 lib/silcske/silcske[_status].[ch].
4922 * Resolve the client entry information in the function
4923 silc_client_channel_message to assure that NULL pointer is not
4924 passed as client entry to the application. */
4926 * Fixed the task timeout calculation to assure that there is
4927 never negative timeouts. The affected file is
4928 lib/silcutil/silcschedule.c.
4930 * Fixed the channel user mode notification sending in server.
4931 It was sent point-to-point to the router (or to server by router)
4932 but it needs to be destined to a channel. The routines now
4933 supports sending the channel user mode notifys to the channels
4934 when announcing clients and channels. Affected files are
4935 silcd/server.c and silcd/packet_receive.c.
4937 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4938 It did not actually replace the old channel entry in the cache.
4939 Affected file lib/silcclient/client_notify.c.
4941 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Fixed a possible crash in silc_packet_send_prepare. It now
4944 assures always that there is enough space in the buffer and
4945 at the tail area of the buffer (for MAC).
4947 Fixed the inbound buffer reallocation in silc_packet_read.
4948 It was old code and did not handle the reallocation correctly.
4951 The affected file is lib/silccore/silcpacket.c.
4953 * Fixed buffer overflow in silc_parse_nickname in the file
4954 lib/silcutil/silcutil.c.
4956 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * make install generates new server keys only if there is not
4961 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4964 Added check that if the NOREPLY is set then we will not send
4965 the away message. This avoids infinite loop of away messages
4966 if both clients are away. The affected file is
4967 lib/silcclient/client_prvmsg.c.
4969 * Fixed client crash if /NICK was given without arguments.
4970 Affected file lib/silcclient/command.c.
4972 * Server does not send the invite list in INVITE command back
4973 to the client if the list was not altered. Added this notion
4974 to the protocol spec as well. Affected file silcd/command.c.
4976 Fixed possible crash in INVITE command by checking the
4977 value of silc_server_get_client_route command.
4979 * Fixed the INVITE notify type handling. The arguments are now
4980 taken in correct order and client does not crash. The affected
4981 file is irssi/src/silc/core/silc-channels.c.
4983 Removed the "Inviting xxx to channel" message from the
4984 client library away and let the application handle it.
4985 Affected file lib/silcclient/command.c. Added that message
4986 to Irssi SILC client's message formats.
4988 * Fixed CMODE command crash in client. It now checks the
4989 amount of arguments correctly and does not crash. The affected
4990 file is lib/silcclient/command.c.
4992 * Do not create new channel automatically in silc_channels_join
4993 but check whether the channel by that name already exists.
4994 Affected file irssi/silc/core/silc-channels.c.
4996 * Do not send the SERVER_SIGNOFF to router if the disconnected
4997 entity was the router. Affected file silcd/server.c.
4999 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5000 SILC client as it was missing from there.
5002 Added the handling of the KICK notify to the Irssi SILC client
5003 as it was missing. Added "you have been kicked" message to
5004 Irssi SILC client's message modules formats.
5006 Added the handing of the KILL notify to the Irssi SILC client
5007 as it was missing. Added the kill message module formats
5010 The affected file is irssi/src/silc/core/silc-channels.c.
5012 * The router did not save the channel mode the server announced.
5013 Affected file silcd/packet_receive.c.
5015 * Fixed a possible crash in INFO command in server. If the
5016 server did not provide the server info it crashed. Affected
5017 file silcd/command.c.
5019 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Fixed the GETKEY command in the server to check also the
5022 global list. Otherwise the GETKEY would not work correctly
5023 in normal SILC server. Affected file silcd/command.c.
5025 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Fixed GETKEY crash, it crashed if the command did not succseed.
5029 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5032 is now real and not just an macro interface to GMP.
5034 Removed the entire GMP from the source tree and imported new
5035 NSS MPI library instead. Reason for removing GMP is that it is
5036 extremely large and compiles extremely slow. The NSS MPI
5037 is only a few files and compiles in less than 10 seconds.
5038 The speed is also about the same as GMP. The MPI is imported
5039 to lib/silcmath/mpi.
5041 If the system has GMP installed we will still use the GMP.
5042 If it is not then the NSS MPI will be compiled.
5044 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Merged a long nickname (127 characters long) crash bugfix from
5047 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5049 * Merged a freed memory reference bugfix from Irssi CVS tree.
5050 Affected file irssi/src/core/commands.c.
5052 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Added the server's public key sving and verification to the
5055 server when performing the SKE. This was missing and the
5056 remote server's (or router's) public key was accepted without
5057 checking whether we have it previously or trust it at all.
5058 Affected file silcd/protocol.c.
5060 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Check in the silc_server_timeout_remote if protocol is active
5063 and make sure that the protocol's final callback is called so
5064 that all memory if freed. Affected file silcd/server.c.
5066 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * silc_server_whois_send_reply crashed the server if the nickname
5069 was 127 characters long. Affected file silcd/command.c.
5071 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added sanity check to the silc_server_new_client. If the hostname
5074 is provided inside username then check that the provided hostname
5075 really is the same as the resolved one. If the hostname was not
5076 resolved then check it from the public key. Affected file is
5077 silcd/packet_receive.c.
5079 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5080 if the server disconnected us and the connection is not valid
5081 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5083 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5084 the library to the lib/silcutil/silcutil.[ch].
5086 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Close log file after open. Affected file
5089 lib/silcutil/silclog.c.
5091 * Check whether sock == NULL in silc_client_send_packet and return
5092 if it is. Affected file lib/silcclient/silcclient.c.
5094 * Check rec->entry == NULL in the Irssi SILC Client before
5095 sending the channel message. Affecte file is
5096 irssi/src/silc/core/silc-servers.c.
5098 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Merged a splitted window bugfix from Irssi CVS tree. The
5101 affected file is irssi/src/fe-text/textbuffer-view.c.
5103 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5104 It did not print nickname.
5106 * Improved the distributions system a bit.
5108 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5111 irssi/src/fe-text/gui-window.c.
5113 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5114 to in-active server. The affected file is
5115 irssi/src/silc/core/client_ops.c.
5117 * Resolve the client in USERS command reply if the entry does
5118 not have username resolved. The affected file is
5119 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5120 command to WHOIS command to really resolve stuff. The USERS
5121 is not used any more in any critical section so WHOIS can
5122 be used even though it might be slower than IDENTIFY.
5124 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5127 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Changed the protocol API a bit more consistent in the
5130 lib/silccore/silcprotocol.[ch].
5132 * Changed the following headers to ROBODoc format:
5134 lib/silccore/silcpayload.h
5135 lib/silccore/silcprotocol.h
5136 lib/silccore/silcsockconn.h
5138 All core library headers are now formatted.
5140 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Fixed a bug in Irssi SILC client; do not show that you are
5143 server/router operator if you really are not. Affected file is
5144 irssi/src/silc/core/client_ops.c.
5146 * Renamed silc_command_free_payload to silc_command_payload_free.
5147 Affected file lib/silccore/silccommand.h
5149 * Added silcmath.h to include the prototoypes of various routines
5150 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5153 * Changed the following headers to ROBODoc format:
5155 lib/silccore/silcchannel.h
5156 lib/silccore/silccommand.h
5157 lib/silccore/silcid.h
5158 lib/silccore/silcidcache.h
5159 lib/silccore/silcmode.h
5160 lib/silccore/silcnotify.h
5161 lib/silccore/silcpacket.h
5162 lib/silcmath/silcmath.h
5164 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Added checking to the server code not to start the server if
5167 ciphers and stuff are not configured properly. Affected files
5168 silcd/serverconfig.[h] and silcd/server.c.
5170 * Changed the layout of the header files of the public interfaces
5171 in the SILC libraries. The new layout supports ROBODoc
5172 documentation tool (and some others) so that it is easy to create
5173 a library reference manual. All the other headers and source
5174 code must still follow the CodingStyle document. Also source
5175 code must not include these ROBODoc stuffs, only the headers.
5176 Furthermore, all public interface headers must now be named
5177 by using `silc' prefix, example: silcapi.h, silccipher.h.
5178 Some files were renamed due to this. All the other headers
5179 must not be used as public interfaces. I will update the
5180 CodingStyle document later. Changed following headers, so far:
5182 lib/silcclient/silcapi.h
5183 lib/silccore/silcauth.h
5184 lib/silccore/silcprivate.h
5185 lib/silccrypt/silcdh.h
5187 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Removed silc_client_packet_send_flush from the client library
5192 as it is not needed. Affected file lib/silcclient/client.[ch].
5194 * Added printing of message of unresolved authentication method
5195 to the Irssi SILC client. Added it to the module formats.
5196 Removed the same message from the client library.
5198 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added new distribution feature, DISTLABEL. Every distribution
5201 can define own preprocessor label that can be used in the
5202 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5203 file distributions, acconfig.h.pre and prepare.
5205 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added Makefile.defines_int to include the actual definitions
5208 for Makefile.defines.in. Tested the new distribution system,
5209 created distributions and tested installation.
5211 * Added AWAY message printing to the Irssi SILC client. Added
5212 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5214 * Added SCONNECT command to call the SILC's CONNECT command.
5215 Cannot use CONNECT directly since Irssi uses that internally.
5216 Affected file irssi/src/silc/core/silc-servers.c.
5218 Added ACTION local command. It is same as ME command but takes
5219 the channel as mandatory argument.
5221 Rewrote some of the Irssi's help files to suite for SILC
5224 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Added Makefile.defines[.in] that should for now on be included
5227 in all Makefile.am file in the source tree. That file includes
5228 all common compilation definitions for SILC source tree.
5230 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Minor changes to the ./prepare script to change the package
5233 name according the distribution name to the configure.in.
5235 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Created new distribution system. Added file `distributions'
5238 that defines all the distributions that can be created out of
5239 the SILC source tree. The ./prepare script now reads that
5240 file to determine how to prepare the distributions. The
5241 first argument to the ./prepare is the name of the distribution
5242 and second is the version of the distribution. If given
5243 without arguments it creates the default (toolkit) distribution
5244 with the default version (defined in ./prepare).
5246 All Makefile.am files that are subject to the distributions
5247 are now named as Makefile.am.pre. These are ./Makefile.am
5248 and lib/Makefile.am. Others may be changed later.
5250 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added invite list, ban list, some key management and connection
5253 error message printing to module formats in the Irssi SILC client.
5255 * Added new silc_client_set_away_message to set the away message
5256 that is back to the person who sent private message. The
5257 affected file lib/silcclient/silcapi.h and the
5258 lib/silcclient/client_prvmsg.c.
5260 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Fixed the private message sending in the Irssi SILC client,
5263 added local command KEY to the Irssi SILC client.
5265 Added key management and key agreement message formats to the
5266 irssi/src/fe-common/silc/module-formats.[ch].
5268 Added USERS (alias WHO) printing, server/router operator
5269 indication and LIST command printing to the module formats.
5271 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Fixed channel joining notify handling, cumode notify handling
5274 from Irssi SILC client.
5276 * Added SILC specific module-formats to the Irssi SILC client so
5277 that SILC specific message hilighting, colors etc is possible.
5278 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5280 Added channel mode, channel user mode, actions, notices,
5281 whois and whowas printing to the the module-formats.c.
5283 * Fixed a bug in channel deletion in the server. The channel
5284 is not left to the cache even if the channel founder auth mode
5285 is set when there are no users anymore on the channel. Affected
5286 file silcd/server.c.
5288 * The silc_net_localhost now resolves the entire hostname including
5289 the domain name. Affected file lib/silcutil/silcnet.c.
5291 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Changed the ask_passphrase client operation to be ascynchronous.
5294 It has now a completion callback and a context that the
5295 application must call after it has got the passphrase from
5296 the user. Affected files lib/silcclient/silcapi.h,
5297 lib/silcclient/protocol.c, lib/silcclient/command.c and
5300 Added SilcAskPassphrase callback that the application calls
5301 to deliver the passphrase to the library.
5303 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5304 The public key verification and especially a certificate
5305 verification is asynchronous procedure.
5307 Added new SILC_SKE_STATUS_PENDING status to indicate the
5308 request is pending and a callback will be called to finalize
5311 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5312 indicate that remote end did not send its public key (or
5313 certificate), even though we require it. Added check for this
5314 condition in the SKE. This was a security bug, now fixed.
5316 Defined new SilcSKEVerifyCbCompletion callback that is called
5317 when the verification process is completed.
5319 The affected files lib/silcske/silcske_status.h and
5320 lib/silcske/silcske.[ch].
5322 * Changed the verify_public_key client operation to be async
5323 as well. Defined SilcVerifyPublicKey callback that is used to
5324 indicate the success of the public key verification process.
5326 Changed the server and client to use the new async client
5329 * Changed the Irssi SILC client's internal scheduler to be called
5330 twice as many times as it used to be. As a result the client
5331 should be a bit faster now. Affected file is
5332 irssi/src/silc/core/silc-core.c.
5334 * Added support to Irssi SILC client of asynchronous public key
5335 verification and passphrase inquiry. Affected file is
5336 irssi/src/silc/core/silc-core.c.
5338 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Do not say "You have left channel %s" in client library.
5341 Moved it to the application. Affected files are
5342 lib/silcclient/command.c and silc/client_ops.c.
5344 * Fixed silc_client_get_clients. Command context was not
5345 duplicated and was freed memory in the callback. Affected
5346 file lib/silcclient/idlist.c.
5348 * Do not say "you are now talking..." on JOIN command in the
5349 client library. The appliation must handle it.
5351 * Do not say ".. changed topic to" in command reply in the
5352 client libary. The application must handle it.
5354 * Fixed TOPIC command sending in the client library.
5356 * Fixed a memory leak in silc_client_command_free in the file
5357 lib/silcclient/command.c.
5359 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Imported a modified version of Irssi client to the source tree.
5362 The Irssi will be used to create a new client called
5363 Irssi SILC. Imported to irssi/.
5365 Added silc_core_init_finish function to the Irssi. Affected
5366 file irssi/configure.in.
5368 A lot changes in the Makefile.ams around the irssi tree.
5370 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Do not rehash if the new size is same as the old size of the
5373 hash table, in the silc_hash_table_rehash*. The affected file
5374 lib/silcutil/silchashtable.c.
5376 * Replaced hash_table_del_by_context calls from the server
5377 (when channel->user_list and client->channels) to the
5378 hash_table_del as it is sufficient and faster.
5380 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added silc_hash_table_list, silc_hash_table_get and the
5383 SilcHashTableList structure to provide an alternative way to
5384 traverse the hash table. The affected files are
5385 lib/silcutil/silchashtable.[ch].
5387 * Changed the server's idlist routines to use the hash table
5388 routines to optimize the code.
5390 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Replaced the client entry's `channel' list and channel entry's
5393 `user_list' list to hash tables for optimized lookup. Changed
5394 the code to use the hash table interface around the code.
5395 Affected file lib/silcd/idlist.[ch].
5397 * Added `auto_rehash' boolean argument to the function
5398 silc_hash_table_alloc to indicate whether the hash table should
5399 auto-rehash when it thinks is appropriate time. It will
5400 increase the hash table size if the there is twice as much
5401 entries in the table than the size of the table, and will
5402 decrease the size if there are twice as less entries than
5403 the size of the table.
5405 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5409 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * silc_idcache_purge_by_context deletes the entry now by context
5412 as it is supposed to do. Affected file lib/silccore/idcache.c.
5414 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5415 client is not anymore valid (WHOWAS givens the info) and not
5416 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5418 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Removed the `data' and `data_len' arguments from the ID Cache
5421 interfaces and added `name' argument. ID Cache does not handle
5422 anymore the binary data only a names associated with given ID.
5424 * When hashing a Client ID with silc_hash_id the entire ID is
5425 not hashed anymore, instead only the hash of the Client ID is
5426 hashed. This way we can access the Client ID from the cache
5427 with Client ID but with the hash of the ID (which is a hash of
5428 the nickname) as well without any difference in performance.
5430 Added also silc_idcache_find_by_id_one_ext to do one on one
5431 searching when we have the actual ID. Added also function
5432 silc_hash_client_id_compare. The affected files are
5433 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5435 * When hashing the name associated with a ID it is always done
5436 in lowercase. This way we can access the cache without worrying
5437 about case-sensitivity, even though, for example nicknames are
5440 * Fixed a bug in server with channel message sending. It put
5441 wrong ID type as destination ID. The affected file
5442 silcd/packet_send.c.
5444 * silc_idcache_del_by_context now deletes from all hash tables
5445 by context. Affected file lib/silccore/idcache.c.
5447 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Changed the client library to use the new ID Cache interface.
5450 Changes around the source tree.
5452 * Added silc_hash_table_rehash_ext to rehash with specific
5453 hash function. Affected file lib/silcutil/silchashtable.[ch].
5455 * Added silc_hash_string_compare to compare two strings in the
5456 hash table. Affected file lib/silcutil/silcutil.[ch].
5458 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Added new function silc_idcache_del_by_context into the
5461 lib/silccore/idcache.[ch].
5463 * Changed the server's ID list routines to use the new ID Cache
5464 interface. Changes around the source tree.
5466 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Added silc_hash_table_del[_by_context]_ext functions in to the
5469 lib/silcutil/silchashtable.[ch].
5471 Removed silc_hash_table_find_all* routines and added new
5472 silc_hash_table_find_foreach to replace them.
5474 Added silc_hash_table_replace_ext function as extended
5475 replacing function. Separated the simple hash table interface
5476 from the extended hash table interface in the file
5477 lib/silcutil/silchashtable.h.
5479 * Fixed minor bugs and changed it to use some of the new
5480 hash table functions in lib/silccore/idcache.c
5482 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Added new function silc_hash_table_find_all to return all keys
5485 in the hash table by the specified key. As the hash table is
5486 collision resistant it also makes it possible to have several
5487 duplicate keys in the hash table. This function may be used to
5488 find all of the keys from the hash.
5490 Added user_context arguments to the SilcHashFunction,
5491 SilcHashCompare and SilcHashDestructor to deliver user specified
5494 Added new fuctions silc_hash_table_find[_all]_ext to do
5495 extended lookup with specified hash and compare functions and
5496 specified user contexts.
5498 Added new function silc_hash_table_add_ext to add the key
5499 with specified hash function and user context.
5501 Added new function silc_hash_table_foreach to traverse all
5502 entrys in the hash table. Added SilcHashForeach callback
5505 Added new function silc_hash_table_del_by_context to delete
5506 the entry only if the context associated with the key matches.
5508 Affected files are lib/silcutil/silchashtable.[ch].
5510 * Removed silc_hash_[server/client/channel]_id and added just
5511 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5512 silc_hash_id_compare to compare two ID's using as the hash table
5513 comparison function. Added also silc_hash_data to hash
5514 binary data and silc_hash_data_compare to compare it.
5516 * Removed silc_idlist_find_client_by_hash as it is not needed
5517 anymore. Affected file silcd/idlist.[ch].
5519 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5520 to use internally the SilcHashTable. The new ID Cache is a lot
5521 faster than the old one. Some of the ID Cache interface was also
5522 rewritten and obsolete and stupid functions were removed.
5524 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added entry_count field to the SilcHashTable to keep the number
5527 of the entries in the table. Implemented the function
5528 silc_hash_table_rehash. Added new function
5529 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5531 Fixed a minor bug in silc_hash_table_free.
5533 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5534 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5535 into the lib/silcutil/silcutil.[ch].
5537 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Implemented a collision resistant hash table into the
5540 lib/silcutil/silchashtable[ch]. See the header and the source
5541 for the SilcHashTable API.
5543 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Merged dotconf version 1.0.2 into lib/dotconf.
5547 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Do not compile anything in lib/silcsim/* if the SIM support
5550 is not enabled. The tree should now compile without problems
5553 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Compiled the SILC under cygwin. Compiled and tested briefly
5556 without problems. More tests needed. The SIMs didn't compile
5559 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5561 * Fixed possible crash in silc_get_username in the
5562 lib/silcutil/silcutil.c.
5564 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Fixed a va_arg in silc/client_ops.c.
5568 * Oops, RC5 routines were named AES and caused some problems
5569 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5571 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added new SilcIDIP structure into the lib/silccore/id.h and
5574 replaced the old `ip' fields from all SILC ID's to that type.
5575 This is a step towards IPv6 support.
5577 The silc_id_get_len takes now the ID as an extra argument.
5578 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5579 both IPv4 and IPv6 based ID's.
5581 The affected files are lib/silccore/id.[ch] and other files
5582 around the tree using these routines.
5584 * Removed the ID length arguments in server from various
5585 silc_server_send_notify_* routines -> they are not needed
5588 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Fixed memory leak in silc_encode_pem_file in the file
5591 lib/silcutil/silcutil.c.
5593 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Check minor version as well in the SKE. Affected files are
5596 silcd/protocol.c and lib/silcclient/protocol.c.
5598 * Added --identifier option to the server so that an identifier
5599 can be when creating the public key for the server. Affected
5600 file is silcd/silcd.c.
5602 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5603 lib/silccrypt/silcpkcs.c.
5605 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Register default ciphers and stuff when using -C option with
5608 the server. Affected file sildc/silcd.c.
5610 * Put back the servers public key filename format, it is better
5611 than the new one. For now, the client keys are saved with the
5612 new filename format. The affected file silc/client_ops.c.
5614 * Implemented the Cipher API for the rest of the ciphers that
5615 did not implement it or implemented it the wrong way.
5617 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Register default ciphers and stuff when using the -S option
5620 in the client. Affected file silc/silc.c. Same also when
5621 creating new key pair with -C option.
5623 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Fixed the silc_verify_public_key client operation function to
5626 save the public keys differently. The fingerprint is now
5627 used as filename and not the hostname. This way also the
5628 client keys are saved uniquely and not with hostnames. The
5629 affected file is silc/client_ops.c.
5631 * Trimmed the silc_hash_fingerprint function to remove extra
5632 whitespaces from the end of the fingerprint. The affected
5633 file is lib/silccrypt/silchash.c.
5637 * Added silc_cipher_register_default function to register all
5638 default ciphers. It can be used when configuration files
5639 does not exist and the application does not want any specific
5640 ciphers in any specific order.
5642 The SilcDList is now used as silc_cipher_list dynamically
5643 allocated cipher list. Removed the static list all together
5644 and now all ciphers must be allocated to the dynamic list.
5645 The silc_cipher_alloc routine was changed to check only the
5648 All silc_cipher_* routines that used to return int returns
5651 The affected files lib/silccrypt/silccrypt.[ch].
5653 * The same thing was done to silc_hash_* as for silc_cipher_*
5654 routines. Affected files lib/silccrypt/silchash.[ch].
5656 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5657 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5658 Added also silc_pkcs_[un]register[_default] functions.
5659 Removed the data_context from the PKCS API.
5661 * Added silc_hmac_register_default function to register default
5662 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5663 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5664 to unregister all hmacs at once.
5666 * Register the default ciphers, hash functions, PKCSs and HMACs
5667 if client's configuration file does not exist. The affected
5670 * The client did not load the hash functions from the SIM
5671 modules at all. Added support for this. Affected file is
5672 silc/clientconfig.c.
5674 * When decoding public key with silc_pkcs_public_key_decode, check
5675 the supported algorithm only if PKCS are registered. Affected
5676 file lib/silccrypt/silcpkcs.c. The same was done with the
5677 silc_pkcs_private_key_decode.
5679 * Fixed the SILC List routines to keep the list always in order.
5680 It used to change the list's order when traversing the list but
5681 not it preserves the order. Affected file lib/trq/silclist.h.
5683 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Added the client library to use the SilcSocketConnection's
5686 reference counter (by silc_socket_dup) to prevent the bug that
5687 the socket object may be freed underneath async operation.
5689 * The name resolv library checking fixes in the configure.in.pre.
5692 * Created new version of the protocol drafts for future
5693 development. The -03 drafts are the ones that will be changed
5694 in the trunk now and the -02 will remain as they are.
5696 * Send list of CUMODE notifys to the router when announcing
5697 the channel users to the router. Affected file silcd/server.c.
5698 If the router receiving channel founder CUMODE for a channel
5699 that already has channel founder it will send CUMODE notify
5700 to the sender to remove the channel founder rights from the
5701 announced client. Affected file silcd/packet_receive.c.
5703 * The CUMODE notify may now use Server ID as well as the entity
5704 who changes the mode. Updated protocool specs.
5706 * Updated INSTALL and README files.
5708 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * New web pages in the http://silc.pspt.fi. The pages was
5715 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Implemented the [DenyConnectin] config section in the server.
5718 Added silc_server_config_denied_conn to check whether incoming
5719 connection is denied. Affected file silcd/serverconfig.[ch].
5721 * Do not check the ports when checking the incoming configuration
5722 data if the port is 0, meaning any. Affected file is
5723 silcd/serverconfig.c.
5725 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed buffer overflow in silc_string_compare in the file
5728 lib/silcutil/silcutil.c.
5730 * Fixed double free in silc_server_command_leave in the file
5733 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Fixed the version checking in the server. Affected file is
5738 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Fixed the configuration data fetching when accepting new
5741 connections in the server. Affected file silcd/server.c.
5743 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Added `sender_entry' argument to the function
5746 silc_server_packet_relay_to_channel so that we can check
5747 whether some destination actually belongs to the same route
5748 the sender belongs (ie, we must not resend the packet to the
5749 sender). Affected file silcd/packet_send.[ch].
5751 * Added `servername' field to the SilcClientEntry in the server
5752 to hold the name of the server where client is from. Affected
5753 file is silcd/idlist.h.
5755 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Moved the channel message encrypting in the router betwen
5758 router connections from silc_server_channel_message to the
5759 silc_server_packet_relay_to_channel since we want to check
5760 whether we have anybody channel before encrypting anything.
5761 Affected files silcd/packet_[receive/send].c.
5763 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Fixed the [AdminConnection] server config section to support
5766 multiple entries. Affected file silcd/serverconfig.c.
5768 * Added support into the server to check the validity of the
5769 incoming connection before executing any KE or authentication
5772 * The connection configuration is now saved to the KE and
5773 connection auth protocol contexts and not fetched anymore in
5774 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5776 * The local hosts listenning address and port is also resolved
5777 now when starting the server. We want to have the socket object
5778 to include the real address and port for the listener. Added
5779 new function silc_net_check_local_by_sock into the files
5780 lib/silcutil/silcnet.[ch].
5782 * Fixed a broadcast bug in server -> do not broadcast if we
5785 * Fixed a routing bug. Do not route broadcast packets ever.
5786 Broadcast packets must be processed always and not routed since
5787 they may be destined to some other host than yourself and thus
5788 would get routed without no good reason. Affected file is
5791 * Added function silc_server_config_is_primary_route to check
5792 whether primary router connection has been configured (a router
5793 configuration that we are initiating). If there is not, we
5794 will assume that there is only two routers in the SILC network
5795 and we will use the incoming router connection as our primary
5796 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5798 * Changed the order of the broadcasting. Broadcast _after_ the
5799 packet has been processed not before. Affected file is
5802 * Fixed a [ClientConnection] parsing bug. The port was never
5803 parsed correctly thus resulting to port 0. Affected file
5804 silcd/serverconfig.c.
5806 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5807 argument and did not set the broadcast packet flag. Affected
5808 file silcd/packet_send.c. Fixed same bug in the function
5809 silc_server_send_notify as well.
5811 * If we receive NEW_ID packet for our own ID in the server, ignore
5814 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Removed the nickname from the Private Message Payload.
5819 Updated the code and the protocol specs.
5821 * Updated protocol specs for submitting to the IETF.
5823 * Tweaked the Random Number Generator a bit. Affected file
5824 lib/silccrypt/silcrng.c. Exported a new function
5825 silc_rng_[global]_add_noise which can be used to add more
5828 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Do not parse packets with different timeout when protocol
5831 is active -> may cause problem with rekey. Affected file
5834 * When server receives signoff notify it must not create
5835 new channel key if the client is on any channels since the
5836 sender of the signoff notify will create it.
5838 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added printing of error messages during SKE protocol from the
5841 failure packet sent by server during SKE. Affected file
5844 * Removed the client's failure_callback handling with timeout
5845 and handle it immediately when received.
5847 * The SKE library returned wrong type in SUCCESS and FAILURE
5848 packets. They must be 32 bit MSB not 16 bit MSB.
5850 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Ok, rewrote the logic of the re-key and now it seems to work.
5853 I tested it on high traffic with frequent re-keys without
5854 problems. Added hmac_receive (and renamed hmac to hmac_send)
5855 in SilcClientConnection in lib/silcclient/client.h and
5856 in SilcIDListData in silcd/idlist.h. Also, removed the
5857 SilcPacketParserContext's cipher and hmac fields as they are
5858 not needed anymore and actually caused some problems when
5859 the ciphers and hmac's changed underneath the packet parser.
5861 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * If re-key protocol is active then process the incoming packets
5864 synchronously since we must assure that icoming packets encrypted
5865 with the old key is processed before the new keys is set to
5866 use. This is true other packets than for REKEY packets.
5867 Affected file silcd/server.c. The same was done to client library
5868 as well, affected file lib/silcclient/client.c.
5870 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Fixed bug in client and server to accept the force send if
5873 the packet is send from silc_[server/client]_packet_process
5874 function. Otherwise the packets are never delivered, oops.
5876 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Disable force sending of packets when REKEY protocol is active.
5879 We must assure that no packet is sent directly when rekey is
5880 performed. All packets must be sent through packet queue.
5881 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5882 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5883 function is silc_[server/client]_packet_send_real to check
5886 * Replaced the SIM paths from example config files to
5887 /usr/local/modules. Also, make install creates now
5888 /usr/local/silc/logs directory to hold all the SILC server
5891 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Made the configure.in.pre work on Solaris. Patch by salo.
5895 * Made all ciphers compatible with non-x86 machines. Defined
5896 CBC mode macros into lib/silccrypt/ciphers_def.h.
5898 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed the make install.
5902 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * When MAC computation fails the silc_packet_decrypt returned 0
5905 even though it was supposed to return -1. Fixed this. The
5906 affected file is lib/silccore/silcpacket.c.
5908 * Do not replace the config files in /etc/silc (in make install)
5909 if they already exist. Affected file ./Makefile.am.
5911 * Do not send re-key packets immediately but through packet queue.
5912 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5914 * Changed silc_net_check_host_by_sock to return FALSE if the
5915 IP/DNS could not be resolved. Though, it returns the IP address
5916 now even if it could not resolve it (but returns also FALSE).
5917 Affected file lib/silcutil/silcnet.[ch].
5919 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added silc_pkcs_decode_identifier to decode the public key's
5922 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5923 Added also silc_pkcs_free_identifier. Added also new context
5924 SilcPublicKeyIdentifier.
5926 * Added -S option to the silc client. It is used to dump the
5927 contents of the specified public key file.
5929 * Changed the PKCS api to return the public key length when
5930 setting the public key.
5932 * Fixed a fatal bug in the public and private key file loading.
5933 Affected file lib/silccrypt/silcpkcs.c.
5935 * Execute the packet parsing for client with zero (0) timeout
5936 if the protocol is active. Affected file silcd/server.c.
5938 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Made the key generation options to the silcd program. Added
5941 -C option, equivalent to client's option.
5943 * Added new [ServerKeys] config section to the server. It
5944 configures the server's public and private key.
5946 * Defined generic Public Key Payload into the protocol
5947 specification to send specific type of public keys and
5950 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5951 public key or certificate.
5953 * Implemented the GETKEY command to the server and to the
5954 client library and on user interface.
5956 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Made preliminary `make install' work.
5960 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Added SilcServerRekey context into silcd/idlist.h.
5964 * Added the PFS support as defined in the specification to the
5965 SKE protocol. Affected files lib/silcske/*.c.
5967 * Added `ske_group' field to the SilcServerRekey context to hold
5968 the number of the SKE group that is used with PFS in re-key.
5969 Affected file silcd/idlist.h.
5971 * Added PFS re-key support to the server. Affected file is
5974 * Added silc_protocol_cancel to cancel execution of the next
5975 state of the protocol. Affected file is
5976 lib/silccore/silcprotocol.[ch].
5978 * Added the re-key support with and without PFS to the client
5979 library. Re-key is performed once in an hour, by default.
5981 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5982 Added silc_client_rekey_callback and silc_client_rekey_final.
5983 Affected files are lib/silcclient/protocol.[ch] and
5984 lib/silcclient/client.[ch].
5986 * Removed the `hmac_key' and `hmac_key_len' fields from the
5987 SilcClientConnection structure; not needed. Affected file is
5988 lib/silcclient/client.h.
5992 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Do not ask whether user wants to use the negotiated private key
5995 for private messages, just use it. Affected file is
5996 silc/local_command.c.
5998 * Added `send_enc_key' and `enc_key_len' fields to the
5999 SilcIDListData structure since they are needed in the re-key
6000 phase. Affected file is silcd/idlist.[ch].
6002 * Implemented the simple re-key protocol into the server.
6003 Affected files silcd/server.c and silcd/protocol.[ch]. The
6004 re-key will be performed once in an hour, by default.
6006 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6007 Added silc_server_rekey, silc_server_rekey_callback and
6008 silc_server_rekey_final.
6010 * Removed Tunneled flag from the protocol. Updated the code
6011 and the specifications.
6013 * Adde `pfs' field to the SilcIDListData to indicate whether
6014 the PFS is to be performed in the re-key. Affected file is
6017 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6020 int64 of at least the xintXX size. If void * is less that 4
6021 bytes uint32 * will be used. Defined bool as boolean.
6023 * Changed _ALL_ unsigned long and unsigned int to uint32,
6024 unsgined short to uint16 in the source tree.
6026 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6027 not handle clients that has entry->data.registered == FALSE.
6028 They are not in the network anymore. Affected file is
6031 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Implemented the sending of the SERVER_SIGNOFF notify in the
6034 server. Affected file is silcd/server.c.
6036 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6037 Added also silc_notify_payload_encode_args into the
6038 lib/silccore/silcnotify.[ch].
6040 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6041 Affected file silcd/packet_receive.c.
6043 * Implemented the SERVER_SIGNOFF notify handling in the client
6044 library. Affected file lib/silcclient/client_notify.c. Also,
6045 implemnted the printing of the SERVER_SIGNOFF info to the
6046 application. Affected file silc/client_ops.c.
6048 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6049 if the deleting was successful. Affected file silcd/idlist.[ch].
6051 * Added support for public key authentication in the connection
6052 authentication protocol in the client library. Affected file
6053 lib/silcclient/protocol.c.
6055 * Changed the server's silc_idlist_get_clients_by_* interface
6056 to support already allocated array so that new entries may be
6057 added to pre-allocated array. Affected file silcd/idlist.[ch].
6058 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6059 and command replies.
6061 * All command reply functions in the server now calls the
6062 pending command callback even if error occured. This way the
6063 error will be delivered to the client as well. Affected files
6064 silcd/command.c and silcd/command_reply.c.
6066 * Fixed INFO command to return local server's info if no server
6067 was provided. Affected file lib/silcclient/command.c.
6069 * Removed RESTART command for good. Updated the code and the
6072 * Rewrote parts of the task system. It is a bit simpler now.
6073 Removed unsued task priorities. The affected files are
6074 lib/silcutil/silctask.[ch].
6076 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Moved the USERS printing from the library to the application.
6079 Affected files lib/silcclient/command.c and silc/client_ops.c.
6081 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added channel key re-key support. The re-key is perfomed
6086 only by the router and is done once in an hour. Added `rekey'
6087 field to the SilcChannelEntry in the server. Affected files
6088 silcd/server.c and silcd/idlist.h.
6090 * Added silc_task_unregister_by_context into the file
6091 lib/silcutil/silctask.[ch].
6093 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added SILC_UMODE_GONE mode to indicate when the client is not
6096 present in the SILC network. Added also support to the local
6097 command AWAY that will set this mode. Added support of showing
6098 "xxx is gone" in WHOIS command. The USERS command shows the
6099 gone status as well.
6101 * Fixed setting server and router operator privileges in the
6102 server's UMODE command. Affected file silcd/command.c.
6104 * Merged the SKE KE1 and KE2 payloads into one payload. The
6105 new KE payload is equivalent to the old KE2 payload.
6107 Cleaned up the SKE Start Payload parsing. It now uses the
6108 simple buffer unformatting to do the parsing. A lot faster
6111 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6112 to the SKE that is used to indicate whether both of the SKE
6113 parties should perform authentication. By default only the
6114 responder performs authentication. By setting this flag also
6115 the initiator must do authentication. By default it is unset
6116 since in normal SKE case, client to server connection, only
6117 the responder should do authentication. When doing SKE between
6118 two clients both should perform authentication. Updated the
6119 code and the protocol specs.
6121 * A little fix to IDENTIFY command in the server. Search the
6122 client first by hash not nickname. Affected file is
6125 * Fixed the silc_client_close_connection to support closing
6126 the client to client connections wihtout deleting too much
6127 data. Affected file lib/silcclient/client.c.
6129 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6130 are received if protocol used to be active but is not anymore
6131 the application would crash due to NULL pointer dereference.
6132 Affected files silcd/server.c and lib/silcclient/client.c.
6134 * Added `hash' field to the SilcClientConnection to include
6135 the hash function negotiated in the SKE protocol.
6137 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6138 to set the channel founder authentication data. A client can
6139 claim the founder rights later by providing the authentication
6140 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6141 This way the channel founder can regain the channel founder
6142 privileges even it is left the channel. This works only on
6143 local server and the client must be connected to the same
6144 server to be able to regain the founder rights. Updated the
6145 protocol specs accordingly.
6147 Added support to the CMODE command in the client to set the
6148 founder auth data. Read the README to see how to set it.
6150 Added support to the CUMODE command to claim the founder
6151 rights. Read the README to see how to do it.
6153 Added support for the founder authentication to the Channel
6154 Entry in the server. Affected file silcd/idlist.h.
6156 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6157 server's CMODE command. Affected file silcd/command.c.
6159 * Added the following new functions into lib/silccore/silcauth.[ch]:
6160 silc_auth_get_method and silc_auth_get_data.
6162 * The server now saves the remote hosts public key to the
6163 SilcIDListData pointer. Affected file silcd/protocol.c.
6165 * The normal server now does not remove the channel entry from
6166 the cache if the founder authentication data is set. It used
6167 to remove it if the founder was the last one on the channel on
6168 the server and left the channel. The auth data is saved and
6169 if the channel is re-joined later the old entry is used with
6170 the old auth data. Affected files silcd/command_reply.c and
6173 * Removed the `pkcs' field from the SilcIDListData structure
6174 in the server; it is not used. Affected file silcd/idlist.h.
6176 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Fixed packet processing on slow links. Partial packets were
6179 never re-processed because the incoming data buffer was cleared
6180 by the application. Application must not directly clear the
6181 sock->inbuf, the packet processing routines handle it. Fixed
6182 this in client library and in server.
6184 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Fixed the WHOIS and IDENTIFY send reply function to really
6187 check whether to send list or just one entry. Affected file
6190 * Cleaned up the LEAVE command's channel key distribution. The
6191 affected file silcd/command.c.
6193 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6194 can enforce the channel mode as well. In that case the ID
6195 includes the ID of the server. The code now enforces the
6196 mode change if the router have different mode than the server.
6198 * The notify client operation with CMODE_CHANGE notify can now
6199 return NULL client_entry pointer if the CMODE was not changed
6200 by client. Application must check for this.
6202 * Added <Server ID> argument to INFO command to support server
6203 info fetching by Server ID.
6205 * Added silc_server_announce_get_channel_users to get assembled
6206 packets of channel users of the specified channel. Affected
6207 file silcd/server.[ch].
6209 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6210 was freed underneath the ID Cache.
6212 * Re-announce clients when the server received CHANNEL_CHANGE
6213 notify from the router. Affected file silcd/packet_send.c.
6215 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6218 crashed since it did not handle the fact that there is no cipher
6219 called "3" and didn't check the error condition. Now fixed.
6221 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6222 flag. It can be used to send message requests.
6224 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Implemented the RESTART command in the client.
6228 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6229 notice type messages. Added notice printing to the user
6232 * The channel keys are not re-generated if the channel's mode
6233 is PRIVKEY, ie private key on the channel exists. Affected
6234 files silcd/server.c and silcd/command.c.
6236 * Fixed a little bug in channel message delivery when channel
6237 private keys are set in the server. Affected file is
6238 silcd/packet_send.c.
6240 * Changed the setting on channel->on_channel = TRUE from the
6241 silc_client_save_channel_key to the JOIN command reply. The
6242 key payload is not received if the private channel key is set.
6243 Affected file lib/silcclient/command_reply.c and the
6244 lib/silcclient/client_channel.c.
6246 * When the CMODE_CHANGE notify is sent and the channel private
6247 key mode is removed the channel key must be re-generated in
6248 other cells as well. Added this support for the router in the
6249 silcd/packet_receive.c.
6251 * Added new local command NOTICE to send notice message on
6252 channel. Affected file silc/local_command.[ch].
6254 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Added new local command ME to the client. It is used to send
6257 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6258 some action. Affected file silc/local_command.[ch].
6260 * Changed channel_message and private_message client operations
6261 to deliver the message flags to the application. Added also
6262 the `flags' arguments to the silc_client_send_channel_message
6263 and silc_client_send_private_message functions. Affected file
6266 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Redefined the Private Message Payload to support private message
6269 keys and to support the new private message flags. Updated
6270 the protocol specs. Flags makes it possible to have for example
6271 CTCP style messages.
6273 * Added new type SilcPrivateMessagePayload and defined an API
6274 for it in the lib/silcclient/silcprivate.[ch].
6276 * Tested private message private keys successfully. Tested the
6277 private message key set, unset and list commands with the new
6280 * Redefined the Channel Message Payload to include the channel
6281 message flags (equal with private message flags) to support
6282 for example CTCP style messages.
6284 * Defined some of the message (for channel and private message)
6285 flags. Updated the protocol specs and added the flags to the
6286 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6288 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added SilcKeyAgreementStatus type to the key agreement routines
6291 to indicate the current status and error if one occured.
6292 The status types are defined in the lib/silcclient/silcapi.h.
6294 * Added new local command KEY that is used to set and unset private
6295 keys for channels, set and unset private keys for private messages
6296 with remote clients and to send key agreement requests and
6297 negotiate the key agreement protocol with remote client. The
6298 key agreement is supported only to negotiate private message keys,
6299 it currently cannot be used to negotiate private keys for channels,
6300 as it is not convenient for that purpose.
6302 * Fixed a minor pending callback setting bug in the function
6303 silc_client_get_client_by_id_resolve, now the function works.
6304 Affected file lib/silcclient/idlist.c.
6306 * Added function silc_net_get_local_port to get local bound
6307 port by socket. Added to lib/silcutil/silcnet.[ch].
6309 * Added `sockets' and `sockets_count' fields to the SilcClient
6310 object. They hold the sockets of the listenning sockets in
6311 the client. Listenning sockets may be for example the key
6312 agreement server. Affected file lib/silcclient/client.[ch].
6313 Added functions the silc_client_add_socket and the
6314 silc_client_del_socket. They are exported to the application
6317 * Added ~./silc/clientkeys to support other client's public keys.
6319 * Renamed verify_server_key client operation to verify_public_key
6320 and added one argument to indicate the type of the connection
6321 (server, client etc.).
6323 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Added silc_server_connection_auth_request to handle the
6326 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6327 silcd/packet_receive.[ch].
6329 * Added silc_server_send_connection_auth_request into the
6330 silcd/packet_send.c to send the connection auth request packet.
6332 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6335 * Fixed the public key authentication in responder side in the
6336 server. The `auth_data' pointer includes the SilcPublicKey
6337 not the path to the public key. Affected file silcd/protocol.c.
6339 * Implemented the public key authentication in the initiator side
6340 in the server. Affected file silcd/protocol.c.
6342 * Removed the [RedirectClient] config section from the server
6343 configuration. Is not needed and I don't want to implement it.
6345 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Cleaned up the CMODE command in the server. It now works
6348 correctly and supports all the modes defined in the protocol.
6349 Affected file is silcd/command.c.
6351 * Added `hmac_name' field to the SilcChannelEntry in the server
6352 to hold the default HMAC of the channel. It can be set when
6353 creating the channel (with JOIN command). Affected files
6356 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6357 type to indicate the change of the current cipher and hmac
6358 on the channel. Client can safely ignore the <cipher> argument
6359 (if it chooses to do so) since the CHANNEL_KEY packet will
6360 force the channel key change anyway. The <hmac> argument is
6361 important since the client is responsible of setting the new
6362 HMAC and the hmac key into use.
6364 * Fixed the CMODE command in the client library as well.
6366 * Tested CMODE command in router environment successfully.
6368 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Show the version of the remote client (or server) when connecting
6371 to the server. It is logged to the log file. Affected file
6372 is silcd/protocol.c.
6374 * Fixed the KILLED notify handling in the client library. The
6375 client must be removed from all channels when receiving the
6378 Also, do not remove the client entry when giving the KILL
6379 command but when the KILLED notify is received.
6381 * Removed silc_idlist_find_client_by_nickname from the server.
6382 Not needed anymore. Affected files silcd/idlist.[ch].
6384 * Implemented the CHANNEL_CHANGE notify type handling to the
6385 server. Affected file silcd/server.c.
6389 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Added silc_server_send_notify_invite to send the INVITE
6392 notify between routers.
6394 * Implemented the INVITE command correctly to the server.
6396 * Implemented the INVITE notify type handling in the server.
6398 * Implemented the INVITE command to the client library and on the
6401 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added function silc_server_get_client_resolve to find the
6404 client entry by ID from all ID lists and then resolve it
6405 (using WHOIS) if it cannot be found. Affected file is
6408 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Implemented the BAN command to the client library.
6412 * The JOIN command in the server now checks the invite list
6415 * Changed the silc_command_reply_payload_encode_va and the
6416 silc_command_payload_encode_va to support that if argument is
6417 NULL it ignores and checks the next argument. Affected file
6418 lib/silccore/silccommand.c.
6420 * Added silc_server_send_notify_ban to send the BAN notify
6421 type between routers.
6423 * Chaned the silc_notify_payload_encode to support that if
6424 argument is NULL it ignores and checks the next argument.
6425 Affected file lib/silccore/silcnotify.c.
6427 * Tested ban lists in router environment successfully.
6429 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Implemented BAN command to the server, in silcd/command.[ch].
6433 * Removed the BAN and INVITE_LIST modes from the CMODE command
6436 * Added function silc_string_match to regex match two strings.
6437 Affected files lib/silcutil/silcutil.[ch].
6439 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Redefined parts of the SilcChannelEntry in the server to support
6442 the new ban and invite lists.
6444 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Redefined the INVITE command. The same command can be used to
6447 invite individuals to the channel but also to manage the invite
6448 list of the channel (to add to and remove from the invite list).
6449 Updated the protocol specs.
6451 * Added new command SILC_COMMAND_BAN that can be used to manage
6452 the ban list of the channel. Updated the protocol specs.
6454 * Removed the channel modes: the SILC_CMODE_BAN and the
6455 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6456 in the CMODE command. The equivalent features are now available
6457 using INVITE and BAN commands. Updated the protocol specs.
6459 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6460 in the network about change in the current ban list. The notify
6461 type is not used by the client.
6463 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6464 support the invite lists.
6466 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Added new function silc_string_regexify that converts string
6469 including wildcard characters into regex string that can
6470 be used by the GNU regex library. Added into the file
6471 lib/silcutil/silcutil.[ch].
6473 Added silc_string_regex_combine to combine to regex strings
6474 into one so that they can be used as one regex string by
6475 the GNU regex library. Added into the file
6476 lib/silcutil/silcutil.[ch].
6478 Added silc_string_regex_match to match two strings. It returns
6479 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6481 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Imported GNU regex to the soruce tree into lib/contrib.
6484 Fixed some compiler warning from the regex.c.
6486 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Fixed MOTD command in the server to work in router environment.
6490 * Fixed the MOTD command in the client library to support
6491 the server argument in the command.
6493 * Added `nickname_len' argument to the silc_idlist_add_client
6494 in the server, as the `nickname' argument may be binary data
6497 * Added silc_idlist_get_channels to return all channels from
6500 * Implemented LIST command to the server. Affected file is
6503 * Implemented the LIST command to the client library and on the
6506 * Added [<user count>] argument to the LIST command reply.
6507 With private channels the user count is not shown.
6509 * Updated TODO and README.
6511 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * The client entry's data.registered must be TRUE even with
6514 global client entry on global client list. The data.registered
6515 is used to check whether the client is anymore in the network,
6516 for example with WHOWAS command so it must be valid.
6518 * Fixed the WHOWAS command in the server. It now actually works
6519 in router environment. Added function into silcd/command_reply.c
6520 silc_server_command_reply_whowas_save.
6522 * Added silc_idlist_purge function to the silcd/idlist.c
6523 to periodically purge the ID Cache.
6525 * Fixed INFO command in the server. It works now in router
6526 environment. Added <server name> argument to the INFO command
6527 reply. Updated the protocol specs.
6529 * Fixed minor bug in silc_idcache_purge to not purge if the
6530 expire value is zero.
6532 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6533 they were buggy because of the WHOWAS information.
6535 * Fixed local command MSG to handle the async resolving of
6536 the remote client properly. It used to fail the first MSG.
6537 Affected file silc/local_command.c.
6539 * Added `data_len' field to SilcIDCache context.
6541 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Update TODO. Todo in commands in the server.
6545 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6548 used by routers as broadcast packet to inform other routers
6549 about the changed user mode.
6551 Implemented the notify handling in the server. Affected file is
6552 silcd/packet_receive.c. Added the function
6553 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6555 * Added new generic Channel Payload and deprecated the New Channel
6556 Payload. The New Channel Payload is now the generic Channel
6559 * Added new argument `mode' to the silc_server_send_new_channel
6560 as it is required in the Channel Payload now.
6562 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6563 and created a new and real SilChannelPayload to represent the
6564 new generic Channel Payload. Implemented the encode/decode
6565 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6567 * Added silc_server_get_client_channel_list to return the list
6568 of channels the client has joined for WHOIS command reply.
6569 Affected file silcd/server.[ch].
6571 * Implemented the channel list sending in the WHOIS command reply
6572 in server and in the client.
6574 Implemented the channel list displaying on the user interface
6575 as well. Affected file silc/client_ops.c.
6577 * Added silc_channel_payload_parse_list to parse list of Channel
6578 Payloads. It returns SilcDList list of SilcChannelPayloads.
6579 Client for example can use this function to parse the list of
6580 channels it receives in the WHOIS command reply. The caller
6581 must free the list by calling silc_channel_payload_list_free.
6582 Affected files lib/silccore/silcchannel.[ch].
6584 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Added one new argument <user mode> to the WHOIS command reply
6587 to return the mode of the user in SILC. Updated the protocol
6590 Implemented it to the server and client.
6592 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Fixed the mode printing on the user interface on joining.
6595 Affected file silc/client_ops.c.
6597 * Implemented the UMODE command and user modes in general to the
6598 client library and to the user interface.
6600 * Implemented the UMODE command to the server.
6602 * The server now sends UNKNOWN_COMMAND error status if client sends
6603 unknown command. Affected file silcd/command.c.
6605 * All server commands now handle the command identifier the right
6606 way when sending the command reply to the client. The client can
6607 use to identify the command replies with the identifier.
6609 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Added silc_server_get_client_route to resolve the route to
6612 the client indicated by the client ID. Affected file is
6615 * Added silc_server_relay_packet as general function to relay
6616 packet to arbitrary destination. This deprecates functions
6617 like _send_private_message_key, _relay_notify etc. Affected
6618 file is silcd/packet_send.[ch].
6620 Removed silc_server_send_key_agreement,
6621 silc_server_send_private_message_key and
6622 silc_server_packet_relay_notify functions from the file
6623 silcd/packet_send.[ch].
6627 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6628 server. Affected file silcd/packet_receive.[ch].
6630 * Implemented the KILL command to the client. Implemented the
6631 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6632 Affected files lib/silcclient/command[_reply].c and
6633 lib/silcclient/client_notify.c. Implemented the KILL notify
6634 printing in the user inteface.
6636 * Fixed a lot silc_parse_nick memory leaks from the client
6637 library in the file lib/silcclient/command.c.
6639 * Changed the silc_server_send_notify_on_channels's `sender'
6640 argument from SilcSocketConnection to SilcClientEntry to
6641 check the sender as entry and not as connection object and not
6642 to send to the client provided as argument. The affected file
6643 is silcd/packet_send.[ch].
6645 * The notify packets that are destined directly to the client used
6646 to not to be processed by the server. Now changed that and the
6647 server processes all notify packets. After relaying the packet
6648 to the client the notify packet is processed in the server.
6650 * The silc_server_free_client_data now checks whether there is
6651 pending outgoing traffic for the client and purges the data to
6652 the network before removing the client entry.
6654 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6657 an client is killed from the SILC Network. Updated the protocol
6660 Added new function silc_server_send_notify_killed to the
6661 silcd/packet_send.[ch].
6663 * Added function silc_server_packet_relay_notify to relay notify
6664 packets that are destined directly to a client. In this case
6665 the server does not process the notify packets but merely relays
6666 it to the client. Affected file silcd/packet_send.[ch].
6668 Added also silc_server_packet_process_relay_notify to check
6669 whereto relay the notify. Affected file is
6670 silcd/packet_receive.[ch].
6672 * Implemented the KILL command to the server.
6676 * Added the backup schema desgined last fall to the protocol
6677 specs for everyone to see. The specification is in the
6678 *-spec-xx.txt draft and the packet type definitions for the
6679 backup routers is in *-pp-xx.txt draft. Thusly, added also
6680 new packet type SILC_PACKET_CELL_ROUTERS.
6682 * A big security problem in the implementation discovered. The
6683 signoff of an client did not cause new channel key generation
6684 which it of course should've done. The channel keys must be
6685 always re-generated when client leaves (or signoffs) the channel.
6686 The silc_server_remove_from_channels funtion now handles
6687 the channel key re-generation.
6689 * Added `sender' argument to the silc_server_send_notify_on_channels
6690 to not to send the client provided as argument. Affected file
6691 silcd/packet_send.[ch].
6693 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Implemented OPER and SILCOPER commands into the server and
6698 * Added silc_auth_verify and silc_auth_verify_data to verify
6699 the authentication directly from the authentication payload.
6700 It supports verifying both passphrase and public key based
6701 authentication. Affected file lib/silccore/silcauth.[ch].
6703 * Added `hash' field to the SilcIDListData structure. It is the
6704 hash negotiated in the SKE protocol. Affected file is
6707 * Slight redesigning of the SilcAuthPayload handling routines.
6708 Do not send SilcPKCS but SilcPublicKey as argument.
6710 * Implemented the public key authentication support to the
6711 serverconfig. The public key is loaded from the provided path
6712 and saved as authentication data to void * pointer. Thus,
6713 changed the unsigned char *auth_data to void *auth_data;
6715 * Fixed SHUTDOWN command to send the reply before the server
6716 is shutdown. :) Affected file silcd/command.c.
6718 * Fixed fatal bug in CONNECT command. The hostname was invalid
6719 memory and server crashed. Affected file silcd/command.c.
6721 * Fixed fatal bug in CLOSE command. The server_entry became
6722 invalid but was referenced later in the command. Affected file
6725 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Fixed fatal bug in failure packet handling. Server ignored
6728 the failure and thus crashed when it came.
6732 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6735 that the command may be executed only once in (about) 2 seconds.
6736 The old SILC_CF_LAG flag is same but allows command bursts up
6737 to five before limiting.
6739 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6740 server code. Various commands now includes the CF_LAG_STRICT
6741 flag to disallow any kind of miss-use of the command.
6743 * Fixed the silc_buffer_unformat to not to allocate any data
6744 if the length of the data is zero. It used to allocate the
6745 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6747 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Changed the format of AdminConnection configuration section
6750 in the server. Added username of the admin to the format.
6751 Affected files silcd/serverconfig.[ch].
6753 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6754 to return admin configuration data by host, username and/or
6757 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Implemented WHOWAS command to the server. Added the functions:
6761 silc_server_command_whowas_parse,
6762 silc_server_command_whowas_send_reply,
6763 silc_server_command_whowas_from_client and
6764 silc_server_command_whowas_from_server
6766 * Added <Client ID> argument to the WHOWAS command reply. Updated
6767 the protocol specs accordingly.
6769 * Implemented WHOWAS command and command_reply to the client
6772 Implemented the WHOWAS printing on the user interface.
6774 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Added new argument to the WHOWAS command reply, the real name.
6777 It is an optional argument. Updated the protocol specs.
6779 * Added SilcIDCacheDestructor callback that is registered when
6780 the SilcIDCache is allocated. The callback is called when
6781 an cache entry in the ID Cache expires, or is purged from the
6782 cache. Added into lib/silccore/idcache.[ch].
6784 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6785 to destruct the client entries when the cache entry expires.
6786 Other ID Cache's in server and in the client library ignores
6789 * If the ID Cache entry's `expire' field is zero then the entry
6790 never expires. Added boolean `expire' argument to the
6791 silc_idcache_add function in the lib/silccore/idcache.[ch].
6792 If it is TRUE the default expiry value is used.
6794 * Added silc_server_free_client_data_timeout that is registered
6795 when client disconnects. By default for 5 minutes we preserve
6796 the client entry for history - for WHOWAS command.
6798 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added support to the server to enforce that commands are not
6801 executed more than once in 2 seconds. If server receives
6802 commands from client more frequently, timeout is registered
6803 to process the commands. Affected file silcd/command.c.
6804 Added new function silc_server_command_process_timeout.
6806 * Changed NICK_NOTIFY handling in client library to check that
6807 if the client's nickname was changed, so there is no need to
6808 resolve anything from the server.
6810 * Removed error printing from the WHOIS and IDENTIFY commands.
6811 If error occurs then it is ignored silently in the client library.
6812 The application, however, may map the received error to
6813 human readable error string. The application currently maps
6814 the NO_SUCH_NICKNAME error to string.
6816 * Made the command status message public to the application. Moved
6817 them from lib/silcclient/command_reply.c to
6818 lib/silcclient/command_reply.h. The application can map the
6819 received command status to the string with the
6820 silc_client_command_status_message function.
6822 * Added check to the server to check that client's ID is same
6823 as the Source ID in the packet the client sent. They must
6826 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added dist-bzip hook to the Makefile.am to make bzip2
6829 compressed distributions.
6831 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Server now enforces the maximum length for the nickname and
6834 the channel as protocol specification dictates. 128 bytes for
6835 nickname and 256 bytes for channel name.
6837 * Moved the WHOIS printing to the application. The client libary
6838 does not print out the WHOIS information anymore, the application
6839 must do it. Renamed silc_client_command_reply_whois_print to
6840 the silc_client_command_reply_whois_save.
6842 The client's idle time is also sent to the application now, and
6843 the idle is shown on screen.
6845 * Added silc_client_command_reply_identify_save to save the
6846 received IDENTIFY entries.
6848 * Do not check for channel private keys in message sending and
6849 reception if the channel does not have the PRIVKEY mode set.
6850 Affected file lib/silclient/client_channel.c.
6852 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6855 just surfaced after chaning the JOIN procedure.
6857 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added silc_client_get_clients_by_list to get client entries
6860 from Client ID list, that is returned for example by JOIN
6861 and USERS command replies. The application should use this
6862 function for example when JOIN command reply is received to
6863 resolve the clients already on the channel (library does not
6864 do that anymore as USERS command reply is not used in the JOIN
6865 procedure anymore). Affected files lib/silcclient/silcapi.h and
6866 lib/silcclient/idlist.c.
6868 * JOIN command reply and USERS command reply returns now SilcBuffer
6869 pointers instead of unsigned char pointers when returning
6870 the client list and mode list.
6872 * Added <Client ID> argument to the JOIN command reply, mainly
6873 for the server to identify for which client the command was
6874 originally sent. Updated protocol specs accordingly.
6876 * Added SilcDlist private_key pointer to the SilcChannelEntry
6877 in the client to support the channel private keys. Affected
6878 file is lib/silcclient/idlist.h.
6880 * Added SilcChannelPrivateKey argument to the function
6881 silc_client_send_channel_message so that application can choose
6882 to use specific private ke if it wants to. If it is not provided,
6883 the normal channel key is used, unless private keys are set.
6884 In this case the first (key that was added first) is used
6885 as the encryption key.
6887 * Implemented the support for channel private key handling.
6888 Implemented the following functions:
6890 silc_client_add_channel_private_key,
6891 silc_client_del_channel_private_keys,
6892 silc_client_del_channel_private_key,
6893 silc_client_list_channel_private_keys and
6894 silc_client_free_channel_private_keys
6896 Affected file lib/silcclient/client_channel.c.
6898 * Added the support for the private keys in the channel message
6899 sending and encryption and in the message reception and
6900 decryption. Affected funtions are
6901 silc_client_send_channel_message and silc_client_channel_message.
6903 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * Added SKE's key verify callback to the client library's
6906 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6908 * Removed the statement that server (or router) must send USERS
6909 command reply when joining to the channel so that the client
6910 knows who are on the channel. Instead, the client list and
6911 client's mode list is now sent in the JOIN command reply to the
6912 client who joined channel. This is better solution.
6914 * Added function silc_server_get_users_on_channel and function
6915 silc_server_save_users_on_channel to the silcd/server.[ch].
6917 * Removed function silc_server_command_send_users from the
6920 * Do not show topic on the client library anymore. The topic is
6921 sent in the command reply notify to the application and the
6922 application must show the topic now.
6924 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added client searching by nickname hash into the IDENTIFY and
6927 WHOIS commands in the server as they were clearly missing from
6928 them. Affected file is silcd/command.c.
6930 * Fixed a bug in private message receiving in the client library.
6931 The remote ID was freed and it wasn't supposed, now it is
6934 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Minor fix to the channel payload; allocate the data area, as it
6937 needs to be of specific length.
6939 * If the key agreement port is zero then the operating
6940 system will define the bound port. Affected files are
6941 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6943 * Added new function silc_channel_payload_decrypt into the file
6944 lib/silccore/silcchannel.[ch].
6946 * Moved the channel message etc, check from silc_packet_decrypt
6947 to applications. The library calls now a generic
6948 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6949 when the packet is either normal or special. This was done to
6950 allow more wide range of checking that was not allowed when
6951 the code was in library. Now applications can do virtually any
6952 checks to the packet and return to the library the decision how
6953 the packet should be processed. Affected files are
6954 lib/silccore/silcpacket.[ch].
6956 Added silc_server_packet_decrypt_check to the server and
6957 silc_client_packet_decrypt_check to the client library.
6959 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6960 to send with specified source and destination information.
6962 * Channel message delivery between routers was broken after the
6963 channel key distribution was fixed earlier. The channel key
6964 was used be to distributed to other routers as well which is not
6965 allowed by the protocol. Now this is fixed and channel keys
6966 really are cell specific and the channel message delivery between
6967 routers comply with the protocol specification.
6969 * Fixed various commands in server to check also the global list
6970 for the channel entry and not just the local list. The affected
6971 file silcd/command.c.
6973 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Added assert()s to buffer formatting and unformatting routines
6976 to assert (if --enable-debug) when error occurs. Affected
6977 file: lib/silcutil/silcbuffmt.c.
6979 * Changed to auto-reconnect to check whether the remote host is
6980 router and register the re-connect timeout if it is. It used
6981 to check that whether we are normal server, but router must do
6982 auto-reconnect with another router as well. Affected file
6985 * Removed the [<key len>] option from CMODE command as the cipher
6986 name decides the key length, nowadays. See the defined ciphers
6987 from the protocol specification.
6989 * Added [<hmac>] option to the CMODE command to define the HMAC
6990 for the channel. Added SILC_CMODE_HMAC channel mode.
6992 * Added [<hmac>] option for the JOIN command so that user can
6993 select which HMAC is used to compute the MACs of the channel
6996 * Added Hmac field to the Channel Message Payload. The integrity
6997 of plaintext channel messages are now protected by computing
6998 MAC of the message and attaching the MAC to the payload. The
6999 MAC is encrypted. Now, it is clear that this causes some
7000 overhead to the size of the packet but rationale for this is that
7001 now the receiver can verify whether the channel message decrypted
7002 correctly and also when private keys are set for the channel the
7003 receiver can decrypt the packet with several keys and check from
7004 the MAC which key decrypted the message correctly.
7006 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7007 lib/silccrypt/silccipher.[ch].
7009 * Added silc_hash_len to return the digest length into the
7010 lib/silcrypt/silchash.[ch].
7012 * Rewrote parts of Silc Channel Payload interface in the
7013 lib/silccore/silcchannel.[ch]. The encode function now also
7014 encrypts the packet and parse function decrypts it.
7016 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Fixed a minor formatting bug in the SKE's key material processing.
7019 It actually might have processed the keys wrong way resulting
7022 * Redefined the mandatory HMAC algorithms and added new algorithms.
7023 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7024 and hmac-md5 truncated to 96 bits. The mandatory is now
7025 hmac-sha1-96. Rest are optional (including the one that used
7026 to be mandatory). Rationale for this is that the truncated HMAC
7027 length is sufficient from security point of view and can actually
7028 make the attack against the HMAC harder. Also, the truncated
7029 HMAC causes less overhead to the packets. See the RFC2104 for
7032 * Added new [hmac] configuration section. The SKE used to use
7033 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7034 is of course wrong. The official names that must be proposed in
7035 the SKE are the ones defined in the protocol specification
7036 (hmac-sha1-96 for example). The user can configure any hmac
7037 using any hash function configured in the [hash] section. At
7038 least, the mandatory must be configured.
7040 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7042 * Added HMAC list to the SKE proposal list. It has now both
7043 hash algorithm list and HMAC list. This makes the protocol
7044 incompatible with previous versions. The SKE now seems to work
7045 the way it is supposed to work, for the first time actually.
7047 * Defined plain Hash algorithms to the protocol specification.
7050 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Implemented support for key agreement packets into the server.
7053 Added functions silc_server_key_agreement and
7054 silc_server_send_key_agreement. Other than these functions,
7055 server has nothing to do with this packet.
7057 * Added support for private message key packets into the server.
7058 Added functions silc_server_private_message_key and
7059 silc_server_send_private_message_key.
7063 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7064 called in the protocol's final callback instead in the END
7065 protocol state. This makes a little more sense and in the same
7066 time in client we can use the same protocol routines for normal
7067 key exchange and to key agreement packet handling as well.
7069 * Added to both client's and server's KE protocol context the
7070 SilcSKEKeyMaterial pointer to save the key material. We will
7071 bring the key material to the protocol's final callback by doing
7072 this. The final callback must free the key material.
7074 * Added SKE's packet_send callback into client's KE protocol
7075 context so that the caller can choose what packet sending function
7076 is used. This way we can use different packet sending when
7077 doing normal SKE when doing key agreement packet handling (in
7078 the key agreement packet handling we do not want to encrypt
7081 * Implemented the responder side of the key agreement routines
7082 in the client. The client can now bind to specified port and
7083 accept incoming key negotiation. The key material is passed
7084 to the application after the protocol is over.
7086 * Implemented the processing of incoming Key Agreement packet
7087 in the client. Added function silc_client_key_agreement to
7090 * Implemented the intiator side of the key agreement routines
7091 in the client. The client can now initiate key agreement with
7092 another remote client. The key material is passed to the
7093 application after the protocol is over.
7095 * Created client_keyagr.c to include all the key agreement
7098 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7099 SILC_TASK_CALLBACK except that it is not static.
7101 * Created client_notify.c and moved the Notify packet handling
7102 from the client.[ch] into that file.
7104 * Created client_prvmsg.c and moved all private message and
7105 private message key routines from the client.[ch] into that file.
7107 * Create client_channel.c and moved all channel message and
7108 channel private key routines from the client.[ch] into that file.
7110 * Changed silc_client_get_client_by_id_resolve to resolve with
7111 WHOIS command instead of IDENTIFY command, in the file
7112 lib/silclient/idlist.c.
7114 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Implemented the SKE's responder side to the Client library.
7118 * When FAILURE is received to the protocol do not trust it
7119 blindly. Register a timeout to wait whether the remote closes
7120 the connection as it should do it, only after that process the
7121 actual failure. This was changed to both client and server.
7123 * Added client_internal.h to include some of the structures
7124 there instead of client.h in lib/silcclient/.
7126 * Added function silc_task_unregister_by_callback to unregister
7127 timeouts by the callback function.
7129 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Some "Incomplete WHOIS info" errors has been appearing on the
7132 log files. Took away the entry->userinfo check from WHOIS
7133 reply sending. The entry->userinfo is now " " if client did not
7134 provide one. I thought this was fixed earlier but something
7135 is wrong still. Let's see if the error still appears.
7137 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Fixed a minor bug in the login when the channel key is
7140 re-generated in the server. It used to generate the key in
7141 wrong order and thus caused problems in the channel traffic.
7143 * Fixed a minor bug in channel key distsribution after
7144 KICK command. The key was not sent to the router even though
7147 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Added silc_ske_process_key_material_data as generic routine
7150 to process any key material as the SILC protocol dictates. The
7151 function is used by the actual SKE library but can be used by
7152 applications as well. This relates to the private message keys
7153 and the channel private keys since they must be processed the
7154 same way the normal SILC session keys. The protocol dictates
7155 this. Affected files: lib/silcske/silcske.[ch].
7157 Added also silc_ske_free_key_material to free the
7158 SilcSKEKeyMaterial structure.
7160 * Defined silc_cipher_set_key function to set the key for
7161 cipher without using the object's method function. The affected
7162 files: lib/silccrypt/silccipher.[ch].
7164 * Implemented silc silc_client_add_private_message_key,
7165 silc_client_add_private_message_key_ske,
7166 silc_client_del_private_message_key,
7167 silc_client_list_private_message_keys and
7168 silc_client_free_private_message_keys functions in the
7171 Added functions silc_client_send_private_message_key to send
7172 the Private Message Key payload and silc_client_private_message_key
7173 to handle incoming Private Message Key payload.
7175 * Added Cipher field to the Private Message Key payload to set
7176 the cipher to be used. If ignored, the default cipher defined
7177 in the SILC protocol (aes-256-cbc) is used.
7179 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Removed lib/silcclient/ops.h file.
7183 Redefined parts of the SILC Client Library API. Created new
7184 file silcapi.h that deprecates the ops.h file and defines the
7185 published Client Library API. Defined also private message key
7186 API and channel private key API into the file.
7188 This is the file that the application must include from the
7189 SILC Client Library. Other files need not be included by
7190 the application anymore.
7192 * Added new key_agreement client operation callback and also
7193 defined the Key Agreement library API for the application.
7195 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7198 is used by clients to request key negotiation between another
7199 client in the SILC network. If the negotiation is started it
7200 is performed using the SKE protocol. The result of the
7201 negotiation, the secret key material, can be used for example
7202 as private message key.
7204 Implemented the Key Agreement payload into the files
7205 lib/silccore/silauth.[ch].
7207 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * Redefined ciphers for the SILC protocol. Added some new ciphers
7210 and defined the key lengths for the algorithms. Changed the
7211 code accordingly. The default key length is now 256 bits.
7213 * Fixed SKE key distribution function silc_ske_process_key_material
7214 when the key length is more than 128 bits. The default key
7215 length in SILC is now 256 bits.
7217 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7218 to indicate unsupported algorithm.
7220 * Renamed rijndael.c to aes.c and all functions as well.
7222 * Fixed a long standing channel key setting bug in client library.
7223 Weird that it has never surfaced before.
7225 * Fixed bug in channel deletion. If the entire channel is removed
7226 then it must also delete the references of the channel entry
7227 from the client's channel list as the client's channel entry and
7228 the channel's client entry share same memory.
7230 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7232 * Implemented CONNECT and SHUTDOWN commands in the client.
7234 * Implemented CLOSE command to the client.
7236 * Added the function silc_idlist_find_server_by_name into the
7237 files silcd/idlist.[ch].
7239 Added the function silc_idlist_find_server_by_conn into the
7240 files silcd/idlist.[ch].
7242 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * DIE command was renamed to SHUTDOWN. Updated the both code
7247 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7248 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7250 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7253 * Added function silc_server_create_connection function to create
7254 connection to remote router. My server implementation actually
7255 does not allow router to connect to normal server (it expects
7256 that normal server always initiates the connection to the router)
7257 so the CONNECT command is only good for connecting to another
7260 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7262 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7263 or some other client was kicked from the channel.
7265 Implemented the handling of the notify type to both client
7268 Implemented silc_server_send_notify_kicked to send the KICKED
7269 notify. It is used to send it to the server's primary router.
7271 * Implemented the KICK command into server and client.
7273 * Added `query' argument to the silc_idlist_get_client function
7274 to indicate whether to query the client from server or not if
7277 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7278 to indicate that the client is not channel founder.
7282 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7284 * Removed the rng context from SilcPacketContext structure and
7285 changed that the packet routine uses the Global RNG API.
7287 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Added support for quit message that client can "leave" on the
7290 channel when it quits the SILC. It is ditributed inside the
7291 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7293 Added silc_server_free_client_data that will take the
7294 signoff message as argument.
7296 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7298 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Updated parts of the protocol specification to keep it up
7303 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7306 payloads in one packet.
7308 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7309 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7310 use now the new List flag.
7312 * Also deprecated the following packet types: REPLACE_ID,
7313 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7315 * Added list support for Notify packet in server.
7317 * Added silc_server_send_notify_channel_change to send the
7318 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7319 the silc_server_send_replace_id.
7321 * Added silc_server_send_notify_nick_change to send the
7322 NICK_CHANGE notify type. Deprecates the function
7323 silc_server_send_replace_id.
7325 * Added silc_server_send_notify_join to send the JOIN notify type.
7326 Deprecates the function silc_server_send_new_channel_user.
7328 * Added silc_server_send_notify_leave to send LEAVE notify type.
7329 Deprecates the function silc_server_send_remove_channel_user.
7331 * Added silc_server_send_notify_cmode and
7332 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7333 types. Deprecates the silc_server_send_set_mode function.
7335 * Added SERVER_SIGNOFF notify type to indicate that server has
7336 quit. This means that all clients on the channel from that
7337 server will drop. This can be also used when netsplit happens.
7339 Deprecated REMOVE_ID packet type since it is not needed anymore
7342 Added silc_server_send_notify_server_signoff to send the
7343 SERVER_SIGNOFF notify type. Deprecates the function
7344 silc_server_send_remove_id.
7346 Added also silc_server_send_notify_signoff to send the
7347 SIGNOFF notify type.
7349 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7350 SILC protocol from this day on. Changed the protocol
7351 specification as well.
7353 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7354 notify type. It is used between routers to notify about
7355 topic changes on a channel.
7357 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7360 * Partly updated the protocol specification to comply with the
7361 changes now made. It is still though a bit outdated.
7363 * The JOIN notify type now takes one extra argument <Channel ID>.
7364 The packet used to be destined to the channel but now the
7365 JOIN type may be sent as list thus it is impossible to
7366 destine it to any specific channel. By adding this argument
7367 it is again possible.
7369 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Added CREDITS file. The CHANGES and CREDITS file will appear
7372 in the distribution as well.
7374 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7377 types in the server's silcd/packet_receive.c.
7379 * Implemented CMODE and CUMODE to work in router environment.
7381 * Fixed minor encoding and decoding buglet from the
7382 lib/silccore/silcmode.c.
7384 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7387 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7389 * Changed all SilcConfigServer* and silc_config_server* to
7390 SilcServerConfig* and silc_server_config*, respectively.
7393 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Associated the ID (client or server ID) to the Authentication
7396 Payload to avoid any possibility of forging. Updated the
7397 protocol specification and the code accordingly.
7399 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * The RSA key length is now save to the RsaKey context in the
7402 key generation process in lib/silccrypt/rsa.c. The key length
7403 is now used to figure out the maximum size of the block allowed
7404 to be encrypted/signed.
7406 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7407 is equivalent to the silc_mp_mp2bin but does not allocate any
7410 * Changed silc_mp_mp2bin API to take length argument. If it is
7411 non-zero then the buffer is allocated that large. If zero, then
7412 the size is approximated using silc_mp_sizeinbase, which however
7415 * Created Global RNG API which is global RNG that application can
7416 initialize. After initializing, any routine anywhere in the
7417 code (including library) can use RNG without allocating a new
7418 RNG object. This was done to allow this sort of use of the
7419 RNG in code that has no chance to allocate RNG object. All
7420 applications currently allocate this and many routines in the
7421 library use this. Affected file lib/silccrypt/silcrng.[ch].
7423 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7424 it to use the Global RNG API.
7426 * Defined Authentication Payload into protocol specification that
7427 is used during SILC session to authenticate entities. It is
7428 used for example by client to authenticate itself to the server
7429 to obtain server operator privileges.
7431 Implemented this payload into the lib/silccore/silcauth.[ch].
7432 Implemented also routines for public key based authentication
7433 as the new protocol specification dictates.
7435 Moved definitions of different authentication methods from
7436 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7438 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7439 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7440 silc_pkcs_verify_with_hash functions into the file
7441 lib/silccrypt/silcpkcs.[ch].
7443 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * The client entry's userinfo pointer must be always valid.
7446 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7447 will fail since it requires the userinfo. Now, the userinfo
7448 is allocated as "" if actual userinfo does not exist. Actually,
7449 it must exist and it is totally Ok to drop client connections
7450 that does not announce the userinfo. However, we will make
7451 this workaround for now.
7453 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7454 to return the remote port by socket.
7456 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7459 SILC_SERVER_PENDING_EXEC and added an new macro
7460 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7461 data or when error occurs while processing the pending command.
7463 Added new argument `destructor' into silc_server_command_pending
7464 and to the SilcServerCommandPending object. This destructor is
7465 now called after calling the pending callback or if error occurs
7466 immediately. If error occurs the actual pending callback won't
7467 be called at all - only the destructor. The destructor may be
7468 NULL if destructor is not needed.
7470 All this applies for client library code as well. Similar
7471 changes were made there as well for the pending commands.
7473 In the client, the application must now allocate the
7474 SilcClientCommandContext with the silc_client_command_alloc
7477 * Added reference counter to the SilcServerCommandContext. Added
7478 function silc_server_command_alloc and silc_server_command_dup
7481 Same type of functions added to the client library for the same
7484 * Removed the cmd_ident from IDListData away since it is now
7485 global for all connections. It is the command identifier used
7486 in command sending and with pending commands. The affected file
7489 * Added reference counter to the SilcSocketConnection objecet to
7490 indicate the usage count of the object. The object won't be
7491 freed untill the reference counter hits zero. Currently only
7492 server uses this, and client ignores it. The client must be
7493 set to use this too later. The affected files are
7494 lib/silccore/silcsockconn.[ch]. Added also the function
7495 silc_socket_dup to increase the reference counter.
7497 This was mainly added because it is possible that the socket
7498 is removed underneath of pending command or other async
7499 operation. Now it won't be free'd and proper DISCONNECTING
7500 flags, etc. can be set to avoid sending data to connection that
7501 is not valid anymore.
7503 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7504 the connection. After that it sets SILC_SET_DISCONNECTED.
7505 It is, however, possible that the socket data is not still freed.
7506 The silc_server_packet_process now checks that data is not
7507 read or written to connection that is DISCONNECTED. The socket
7508 get's freed when the reference counter hits zero.
7510 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * Changed the client operation API: channel_message operation's
7513 `sender' is now the client entry of the sender, not the nickname
7514 and the `channel' is the channel entry, not the channel name.
7516 In the private_message operation the `sender' is now also the
7517 client entry of the sender not the nickname.
7519 Affected file is lib/silcclient/ops.h and all applications
7520 using the client operations.
7522 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Moved the calling of ops->connect() from connect_to_server_final
7525 into receive_new_id functin since that is the point when the
7526 client is actually allowed to send traffic to network. The
7527 affected file is lib/silcclient/client.c.
7529 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7532 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7533 (if needs broadcasting) instead of broadcasting the packets one
7534 by one which would make a burst in the network traffic.
7536 * Added `broadcast' argument to the functions in silcd/server.[ch]
7537 silc_server_create_new_channel[_with_id] to indicate whether
7538 to send New Channel packet to primary router.
7540 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Added new function into the silcd/server.[ch] files:
7543 silc_server_create_new_channel_with_id to create new channel with
7544 already existing Channel ID.
7546 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7547 lib/silccore/silcpacket.h. This packet is used t send list of
7548 Set Mode payloads inside one packet. Server uses this to set
7549 the modes for the channels and clients on those channels, that it
7550 announced to the router when it connected to it. The protocol
7551 specification has been updated accordingly.
7553 * The silc_server_new_channel did not handle the packet coming
7554 from normal server as it normally does not send that. However,
7555 when it announces its channels it does send it. Implemented
7556 the support for that.
7558 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7559 into the file lib/silccore/id.h.
7561 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Fixed memory leaks in the functions silc_idlist_del_client,
7564 silc_idlist_del_channel and silc_idlist_del_server in the file
7565 silcd/idlist.c. All of those leaked like a sieve.
7567 * Fixed some small memory leaks in the client's function
7568 silc_client_notify_by_server.
7570 * Added functions into silcd/server.c: silc_server_announce_clients,
7571 silc_server_announce_channels and silc_server_announce_server.
7572 These functions are used by normal and router server to announce
7573 to its primary router about clients, channels and servers (when
7574 router) that we own. This is done after we've connected to the
7577 These functions effectively implements the following packet types:
7578 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7579 and SILC_PACKET_NEW_ID_LIST.
7581 * Added new functions into the silcd/packet_receive.[ch]:
7582 silc_server_new_id_list, silc_server_new_channel_list and
7583 silc_server_new_channel_user_list to handle the incoming
7584 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7586 * Added support of changing Channel ID in the function
7587 silc_server_replace_id. If the server that announces a channel
7588 to the router already exists in the router (with same name but
7589 with different Channel ID), router is responsible to send
7590 Replace ID packet to the server and force the server to change
7591 the Channel ID to the one router has.
7593 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7594 client that the Channel ID has been changed by the router. The
7595 normal server sends this to the client. Client must start using
7596 the new Channel ID as the channel's ID.
7598 Implemented handling of this new type into lib/silcclient/client.c
7599 into the function silc_client_notify_by_server.
7601 * Added new function silc_idlist_replace_channel_id into the files
7602 silcd/idlist.[ch] to replace the Channel ID.
7604 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Call silc_server_command_identify_check always when processing
7607 the IDENTIFY command in silcd/command.c
7609 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7611 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7612 send keepalive packets. The packet can be sent by clients,
7613 servers and routers.
7615 Added function silc_socket_set_heartbeat into the file
7616 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7617 If not set, the heartbeat is not performed. The actual
7618 heartbeat is implemented in the low level socket connection
7619 library. However, application is responsible of actually
7622 Added silc_server_send_heartbeat to send the actual heartbeat
7623 packet into silcd/packet_send.[ch]. Server now performs
7624 keepalive with all connections.
7626 * Added silc_task_get_first function into lib/silcutil/silctask.c
7627 to return the timeout task with shortest timeout. There was a bug
7628 in task unregistration that caused problems. TODO has been
7629 updated to include that task system must be rewritten.
7631 * The client library will now resolve the client information when
7632 receiving JOIN notify from server for client that we know but
7633 have incomplete information.
7635 * Rewrote parts of silc_server_remove_from_channels and
7636 silc_server_remove_from_one_channel as they did not remove the
7637 channel in some circumstances even though they should've.
7639 * Encryption problem encountered in server:
7641 The LEAVE command used to send the Channel Key packet to the
7642 router immediately after generating it. However, the code
7643 had earlier sent Remove Channel user packet but not immediately,
7644 ie. it was put to queue. The order of packets in the router
7645 was that Channel Key packet was first and Remove Channel User
7646 packet was second, even though they were encrypted in the
7647 reverse order. For this reason, MAC check failed. Now, this
7648 is fixed by not sending the Channel Key packet immediately but
7649 putting it to queue. However, this is more fundamental problem:
7650 packets that are in queue should actually not be encrypted
7651 because packets that are sent immediately gets encrypted
7652 actually with wrong IV (and thus MAC check fails). So, packets
7653 that are in queue should be encrypted when they are sent to
7654 the wire and not when they put to the queue.
7656 However, the problem is that the current system has not been
7657 designed to work that way. Instead, the packet is encrypted
7658 as soon as possible and left to the queue. The queue is then
7659 just purged into wire. There won't be any fixes for this
7660 any time soon. So, the current semantic for packet sending
7663 o If you send packet to remote host and do not force the send
7664 (the packet will be in queue) then all subsequent packets to the
7665 same remote host must also be put to the queue. Only after the
7666 queue has been purged is it safe again to force the packet
7669 o If you send all packets immediately then it safe to send
7670 any of subsequent packets through the queue, however, after
7671 the first packet is put to queue then any subsequent packets
7672 must also be put to the queue.
7674 Follow these rules and everything works fine.
7676 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Added new function silc_server_remove_clients_by_server to
7679 remove all client entries from ID list when the server connection
7680 is lost. In this case it is also important to invalidate all
7681 client entires as they hold the invalid server entry. This
7682 fixes fatal bug when server has lost connection and will reconnect
7685 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Made some sanity checks to silc_server_daemonise like to check
7688 whether the requested user and group actually exists.
7690 * Added sanity check to SKE's silc_ske_responder_finish to check
7691 that the public and private key actually is valid.
7693 * Invalidate the client's nickname when receiving Replace ID
7694 packet and the Client ID is being replaced. This means that the
7695 server will query the nickname if someone needs it (client)
7698 * Sort the ID Cache in client library when the ID Cache data
7699 has changed (needs sorting).
7701 * Do not allow for SILC client to create several connections to
7702 several servers. The client does not support windows right now
7703 and generating multiple connections causes weird behaviour.
7705 Irssi-silc client does support windows and can handle several
7706 connections without problems, see: www.irssi.org and SILC plugin.
7708 * Fixed some places where client was added to the IDList. The
7709 rule of thumb is following (in order to get everything right):
7710 If the client is directly connected local client then the
7711 `connection' argument must be set and `router' argument must be
7712 NULL to silc_idlist_add_client function. If the client is not
7713 directly connected client then the `router' argument must
7714 bet set and the `connection' argument must be NULL to the
7715 silc_idlist_add_client function.
7717 * The funtion silc_server_packet_send_local_channel actually did
7718 not check whether the client was locally connected or not. It
7719 does that now. Fixed a bug related to LEAVE command.
7721 * Fixed Remove Channel User payload parsing bug in server's
7722 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7724 * The server's silc_server_save_channel_key now checks also the
7725 global ID list for the channel as it might not be in the local
7726 list. Fixed a bug related to LEAVE command.
7728 * Is this the end of the [<unknown>] buglet that has been lurking
7729 around for a long time? A little for loop fix in server's
7730 silc_server_command_whois_parse that is used by both IDENTIFY
7731 and WHOIS command. At least, this was a clear bug and a cause
7732 of one type of [<unknown>] buglet.
7734 * WHOIS and IDENTIFY commands call the function
7735 silc_server_command_[whois/identify]_check function even if
7736 we are not router server.
7738 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Added --with-gmp configuration option. If set the GMP
7741 is always compiled in the SILC source tree. If not set then
7742 it is checked whether the system has the GMP3 installed. If
7743 it has then the GMP won't be compiled (the system's headers
7744 and library is used), if it doesn't have it then the GMP is
7745 compiled in the SILC source tree.
7747 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Changed RSA private exponent generation to what PKCS #1
7750 suggests. We try to find the smallest possible d by doing
7751 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7752 not security fix but optimization.
7754 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Added new config entry [Identity] to fork the server and run
7757 it as specific user and group. A patch from Bostik.
7759 * Imported Dotconf configuration library into lib/dotconf.
7760 This will be used to create the SILC configuration files later.
7761 It will appear in the distsribution after this commit.
7763 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7765 * A big code auditing weekend happening. Auditing code for
7766 obvious mistakes, bugs and errors. Also, removing any code
7769 Removed files for being obsolete:
7771 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7772 inline in the file lib/silcutil/silcbuffer.h)
7774 o lib/silcutil/silcbufutil.c (the header has inline versions)
7776 Changed code to fix possible error conditions:
7778 o The buffer formatting routines now check that the destination
7779 buffer really has enough space to add the data. This applies for
7780 both buffer formatting and unformatting
7781 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7782 unformatting was changed to accomodate following rules:
7783 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7784 sent to the function while XXX_*STRING will not allocate or copy
7785 the data into the buffer. Instead it sets the pointer from the
7786 buffer into the pointer sent as argument (XXX_*STRING used to
7787 require that the pointer must be allocated already). This change
7788 makes this whole thing a bit more consistent and more optimized
7789 (note that the data returned in the unformatting with XXX_*STRING
7790 must not be freed now). The routines return now -1 on error.
7792 o Tried to find all code that use buffer_format and buffer_unformat
7793 and added return value checking to prevent formatting and
7794 especially unformatting errors and possible subsequent fatal
7797 o Changed ske->x and ske->KEY to mallocated pointers in
7798 lib/silcske/silcske.h. Fixed possible data and memory leak.
7800 o Added return value checking to all *_parse* functions. Fixed
7801 many memory leaks as well.
7803 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7804 so that buffer overflows would not happen. All code now also
7805 checks the return value as it can fail.
7807 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7809 * Added reconnection support to server if the normal server looses
7810 its connection to the router (for example if router is rebooted).
7811 The server performs normal reconnection strategy implemented
7812 to the server. Affected file silcd/server.c.
7814 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * Added new packet type SILC_PACKET_SET_MODE that is used to
7817 distribute the information about changed modes (for clients,
7818 channels and clients channel modes) to all routers in the
7819 network. Updated the protocol specification accordingly.
7821 Added functions into silcd/packet_send.c and
7822 silcd/packet_receive.c: silc_server_send_set_mode,
7823 silc_server_set_mode.
7825 Added new files silcmode.[ch] into lib/silccore that implements
7826 the encoding and decoding of Set Mode Payload. Added new type
7827 SilcSetModePayload. Moved the definitions of different modes
7828 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7830 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Oops, a little mistake in server's connection authentication
7833 protocol. The protocol is not ended with FAILURE but with
7834 SUCCESS if the authentication is Ok. :) Affected file is
7837 * Implemented NICK_CHANGE notify handling in server in the file
7838 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7839 the local clients on the channel. After the changing nickname
7840 in router environment snhould work and the [<unknown>] nickname
7841 should appear no more.
7843 The silc_server_replace_id function that receives the Replace ID
7844 payload now sends the NICK_CHANGE notify type also in the file
7845 silcd/packet_receive.c
7847 * Changed WHOIS and IDENTIFY command to support the maximum amount
7848 of arguments defined in protocol specs (3328 arguments). This
7849 fixed a bug that caused problems when there were more than three
7852 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7854 * Added extra parameter, command identifier, to the
7855 silc_client_send_command so that explicit command identifier
7858 Changed that ID list routines uses specific command identifier
7859 when sending WHOIS/IDENTIFY requests to the server so that they
7860 can be identified when the reply comes back.
7862 Affected files lib/silcclient/command.[ch],
7863 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7865 * Added `sender' argument to silc_server_packet_send_to_channel
7866 to indicaet the sender who originally sent the packet to us
7867 that we are now re-sending. Ignored if NULL. Affected file
7868 silcd/packet_send.[ch].
7870 * Added some server statistics support in silcd/server_internal.h
7871 SilcServerStatistics structure and around the server code. Also
7872 send some nice statistics information when client is connecting
7875 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Fixed channel ID decoding in server's JOIN command reply in
7878 silcd/command_reply.c
7880 * Fixed braodcasting of replace ID payload to not to send it if
7881 we are standalone server in silcd/packet_receive.c.
7883 * Fixed all channel message sending routines to not to send
7884 packets to clients that has router set, since they are routed
7885 separately in the same function earlier. Affects file
7886 silcd/packet_send.c and all channel packet sending functions.
7888 * In USERS reply, res_argv[i] are not allocated, the table
7889 is allocated. Thus changed that free the table, not its
7892 * In server's whois_check and identify_check if the client is
7893 locally connected do not send any WHOIS commands - they are not
7896 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7898 * Fixed some minor bugs in client when sending WHOIS command. The
7899 arguments was in wrong order.
7901 * Removed statis function add_to_channel from server in
7902 silcd/command.c that was previously used with the joining but
7905 * Tested USERS command in router environment successfully with two
7906 routers, two servers and two clients.
7908 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7910 * Reorganized the USERS command and command reply in client library
7911 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7912 When the command is given by user we register a pending command
7913 callback that will reprocess the command after the reply has been
7914 received from the server. When reprocessing the packet we then
7915 display the information. Thus, the USERS information is displayed
7916 now in the command callback instead of in the command reply
7917 callback. The processing of the command is same as previously
7918 when server has sent the command reply in the JOINing process.
7920 * Added to USERS command in silcd/command_reply.c to join the client,
7921 we didn't use to know about, to the channel after we've created
7922 a client entry for it. Also, for clienet we did know already still
7923 check whether it is on the channel or not and add it if not.
7925 * Removed silc_server_command_join_notify as the function and its
7928 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7930 * Changed the client's pending command handling to the same as the
7931 server's pending command handling. It is also now possible to
7932 execute command reply functions from other command reply
7933 function as the function callbacks for commands and command
7934 replies are one and same. The pending commands are not static
7935 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7936 in client connection context. Thus, pending commands are server
7937 connection specific as it is convenient.
7939 Changed the function silc_client_command_pending and
7940 silc_client_command_pending_del and added new function
7941 silc_client_command_pending_check. Removed the
7942 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7945 * Added cmd_ident, current command identifier, to the client
7946 connection context in lib/silcclient/client.h to keep track on
7947 command identifiers used in command sending. Client's command reply
7948 function handling now supports the mandatory command identifiers.
7950 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7951 funtions in client to fully support pending command callbacks.
7953 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7954 as one of the arguments to the application in the command reply
7957 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7958 before first releasing SILC but came back. Now it is removed again
7959 and should come back nomore. The FORWARDED flag was used only
7960 by the JOINing procedure by forwarding the command packet to router.
7961 Now, the JOINing procedure has been changed to more generic (due
7962 to various router environment issues) and FORWARDED is not needed
7963 anymore for anything. The protocol specification is yet to be
7966 Now, removed silc_server_packet_forward from server and the flag
7967 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7969 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7971 * Renamed NAMES command to USERS command. The NAMES was named that
7972 due to historical reasons. Now it is renamed. Also, rewrote
7973 parts of the USERS command. The nickname list is not sent anymore
7974 by the server. Only Client ID and mode lists are sent in the USERS
7975 command. Changed this also to the protocol specification.
7977 The client now resolves the names and stuff after it receives
7978 the USERS list from the server when joining to the channel.
7980 * WHOIS and IDENTIFY commands has been changed to support multiple
7981 Client ID's per command. One can now search for multiple users
7982 in the network by sending only one WHOIS or IDENTIFY command.
7983 Changed the code and the protocol specifications.
7985 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7986 uses silc_server_command_whois_parse to parse the request. */
7988 * If normal server, do not parse the WHOIS and IDENTIFY requests
7989 before sending it to the router. Saves some time.
7991 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7993 * Fixed JOIN command on client library. Wrong number of arguments
7994 used to crash the client.
7996 * Added silc_server_channel_has_global function to check whether
7997 channel has global users or not.
7999 * Added silc_server_channel_has_local function to check whether channel
8000 has locally connected clients on the channel.
8002 * The silc_server_remove_from_one_channel now checks whether the
8003 channel has global users or not after given client was removed from
8004 the channel. It also checks whether the channel has local clients
8005 on the channel anymore. If it does not have then the channel entry
8006 is removed as it is not needed anymore.
8008 * The silc_server_notify now checks on JOIN notify whether the joining
8009 client is one of locally connected or global. If it is global then
8010 the channel has now global users on the channel and that is marked
8011 to the channel entry. Also, it now saves the global client to
8012 global list who is joining and JOINs it to the channel. This is
8013 for normal server, that is.
8015 Changed silc_server_send_notify_on_channel,
8016 silc_server_packet_relay_to_channel and
8017 silc_server_packet_send_to_channel check if we are normal server
8018 and client has router set (ie. global client) do not send the
8019 message to that client, as it is already routed to our router.
8021 * Implemented LEAVE notify type handling in silc_server_notify
8024 * Tested LEAVE command in router environment successfully. Tested
8025 with two routers, two servers and two clients.
8029 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8031 * Implemented SIGNOFF notify type handling in silc_server_notify
8034 * silc_server_remove_id now removes the client entry from all channels
8035 it has joined and thusly sends SIGNOFF notify type.
8037 * Rewrote the NAMES list generation in server by removing two excess
8038 loops. The lists are created now inside one loop.
8040 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8042 * silc_server_remove_channel_user checks now also global list
8043 for channel and client.
8045 * silc_server_new_channel_user checks now both local and global
8046 list for channel and client. Fixed a bug in client id decoding.
8047 Used to decode wrong buffer.
8049 * silc_server_channel_message checks now both local and global
8050 list for channel entry.
8052 * Tested channel joining (hence JOIN) in router environment
8053 successfully. Tested with two routers, two servers and two
8056 * Tested channel message sending in router environment successfully.
8058 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Added silc_server_save_channel_key into server.[ch] to save the
8061 received channel key in Channel Key payload processing. It is
8062 also used in JOIN command reply handling.
8064 Equivalent function silc_client_save_channel_key added into
8065 client.[ch] into client library.
8067 * Changed JOIN command reply to send information whether the channel
8068 was created or not (is existing already) and the channel key
8069 payload. Changed protocol specs accordingly.
8071 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8072 the request was sent by ID and not by nickname. Crashed on
8075 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8077 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8078 now correctly save the received data.
8080 * silc_server_free_sock_user_data now notifies routers in the
8081 network about entities leaving the network.
8083 At the same time implemented functions silc_server_remove_id
8084 and silc_server_send_remove_id to receive and send REMOVE_ID
8085 packets. The packet is used to notify routers in the network
8086 about leaving entities. The ID removed will become invalid in
8089 * Added function silc_idlist_del_server into server. Removes and
8090 free's server entry from ID list.
8092 * silc_server_private_message function now checks, if we are router,
8093 that the destination ID really is valid ID, naturally.
8095 * In router when NEW_ID packet is received (for new client) the
8096 hash of the Client ID is saved in the ID Cache but the
8097 client->nickname is set to NULL, instead of putting the hash
8100 IDENTIFY command now also checks that client->nickname must be
8101 valid. If it is not if will request the data from the server who
8102 owns the client. Added new function
8103 silc_server_command_identify_check.
8105 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8106 to set the command to already allocated Command Payload.
8108 * Tested private message sending in router environment with two
8109 routers, two servers and two clients. Fixed minor bugs and now
8112 * Fixed segfault from client's NAMES command. Used to crash if
8115 * Forwarded packets must not be routed even if it is not destined
8116 to the receiver. Changed server code comply with this.
8118 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8120 * Added `require_reverse_mapping' boolean value to ServerParams
8121 structure. If TRUE (not default) the server will require that
8122 the connecting host has fully qualified domain name.
8124 If the reverse mapping is not required and hostname could not be
8125 found the IP address is used as hostname.
8127 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8129 * Implemented version string checking to both client and server.
8130 The check is incomplete currently due to the abnormal version
8131 strings used in development version of SILC.
8133 * Changed all command functions in server to use the new
8136 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Changed char *data to unsigned char *data in ID Cache system to
8139 support binary data as ID Cache data. Changed code to support
8140 binary data in lib/silccore/idcache.c.
8142 * Renamed silc_server_packet_relay_command_reply to
8143 silc_server_command_reply as it is normal packet receiving
8144 function. Rewrote the function to accept command replys for
8145 servers and not only for clients.
8147 * Mark remote router always as registered server if we are connecting
8148 to it. Otherwise, commands sent by the router to us are ignored.
8150 * All ID List find routines now returns the ID Cache Entry pointer
8151 as well if requested.
8153 * WHOIS command works now in router environment, tested with two
8154 routers, two servers and two clients.
8156 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8157 in router environment (as it is almost equivalent to WHOIS) but
8158 hasn't been tested thoroughly. Added new functions:
8160 silc_server_command_identify_parse
8161 silc_server_command_identify_send_reply
8162 silc_server_command_identify_from_client
8163 silc_server_command_identify_from_server
8165 * Disabled route cache adding because adding two different ID's with
8166 same IP replaces the old cache entry thus giving wrong route.
8167 The entry->router->connection is always the fastest route anyway
8168 so route cache may not be needed. Of course, new routes maybe
8169 established after receiving the ID when the entry->router->connection
8170 might not be anymore the most optimal.
8172 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8174 * Add route cache for received ID for fast routing.
8176 * Added silc_server_packet_route to route received packet on router
8177 that is not destined to us.
8179 * Renamed silc_server_get_route to silc_server_route_get.
8181 * Added id_string and id_string_len fields into SilcServer to
8182 include encoded ServerID for fast comparing without excess
8183 encoding of the ID's.
8185 * Cleaned up WHOIS command on server side. Added following static
8188 silc_server_command_whois_parse
8189 silc_server_command_whois_check
8190 silc_server_command_whois_send_reply
8191 silc_server_command_whois_from_client
8192 silc_server_command_whois_from_server
8194 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8195 arguments in command replies. All command functions should be
8196 updated to use this macro.
8198 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Minor typo fixes on command reply handling on server.
8202 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added silc_server_command_add_to_channel internal routine to add
8205 the client to the channel after router has created the channel and
8206 sent command reply to the server.
8208 * Added generic silc_server_send_command to send any command from
8211 * Use static buffer with ID rendering instead of duplicating data.
8213 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8215 * Fixed a channel user mode bug when joining to a channel server gave
8216 everybody channel founder rights, oops.
8218 * We mark ourselves as the router of the incoming server connection
8219 if we are router ourselves. This way we can check in some packet
8220 sending functions whether it is locally connected server. For
8221 incoming router connections we put NULL.
8223 * For router sending packets locally means now always sending the
8224 packet cell wide; to local clients and local servers. For normal
8225 server sending packet locally means sending it to only local
8228 * Fixed the JOIN command to really work in router environment. If the
8229 channel is created it is always created by the router. Router is
8230 also responsible of making the initial joining to the channel,
8231 sending JOIN notify to the sending server and distributing
8232 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8233 does not exist server doesn't do anything else but forward the
8234 command to the router which performs everything.
8236 * Added silc_server_send_channel_key function to send the Channel Key
8239 * Added silc_server_create_channel_key to create new channel key. The
8240 channel key is now re-generated everytime someone joins or leaves
8241 a channel, as protocol dictates. Note: channel->key_len is the
8244 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8246 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8247 packet_receive.[ch] to separate packet sending and receiving
8248 routines. The server.[ch] now includes everything else including
8249 actual packet processing (writing and reading data) and other
8252 Renamed silc_server_private_message_send_internal to
8253 silc_server_send_private_message. The routine is still though
8254 used only to relay private messages as server does not send
8255 private messages itself.
8257 Renamed silc_server_new_channel to silc_server_create_new_channel
8258 and added new function sicl_server_new_channel that handles the
8259 incoming New Channel packet. Added also new sending function
8260 silc_server_send_new_channel to send New Channel Payload.
8262 * Added new function silc_server_notify to process incoming notify
8263 packet to the server/router. Server may then relay the notify
8264 to clients if needed.
8266 * Added new function silc_server_new_channel_user to process incoming
8267 New Channel User packet. Router will redistribute the packet and
8268 send JOIN notify to its local clients and locally connected servers
8269 if needed. Normal server will send JOIN notify to its local client
8270 on same channel when received this packet. Added also corresponding
8271 sending function silc_server_send_new_channel_user to sent the
8274 * Added boolean route argument to send_notif_to_channel and
8275 packet_send_to_channel functions to attempt to route the packet
8276 if it is TRUE and send only locally if it is FALSE.
8278 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * silc_server_replace_id now broadcasts the received replace ID
8281 packet if it is not broadcast packet already. The router must
8282 broadcast to inform other routers about changed ID.
8284 * Added backpointer to server's router into SilcServer context in
8285 silcd/server_internal.h.
8287 * Fixed silc_server_packet_broadcast to send correct broadcast
8290 * The channel key is now distributed to the local client as soon
8291 as it is received from the router (in router environment) so that
8292 no other packet may be sent for the channel until client has
8295 * silc_server_remove_channel_user now broadcasts the received
8296 Remove Channel User packet if it is not broadcast packet already.
8297 The router must broadcast to inform other routers about removed
8300 * Added users field into SilcPacketContext that is a reference count
8301 of the context. One can increase the reference count by calling
8302 silc_packet_context_dup which is now changed to just increase the
8303 reference count instead of duplicating the data. The reference
8304 count is decresed by calling silc_packet_context_free that will
8305 free the data after the reference count hits zero.
8307 For now on the packet context and everything allocated into it
8308 (including the raw packet from network) must be freed by calling
8309 the new silc_packet_context_free function. Added also new function
8310 silc_packet_context_alloc that must be used now to allocate the
8311 context. This also means that if a routine is asynchronous from
8312 silc_[client/server]_packet_parse_type the packet context must
8313 be duplicated by calling silc_packet_context_dup. Otherwise it
8314 gets free'd after silc_[client/server]_packet_parse_type returns.
8315 Also, one must remember that if packet is duplicated then its
8316 reference count must be decresed by calling the free function as
8317 many times as it was duplicated.
8319 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8320 from both client and server.
8322 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8324 * Made joining to a channel working in router environment.
8326 * Cleaned up JOIN command on server side and create function
8327 silc_server_command_join_channel internal routine to make the
8330 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Changed silc_command_pending list to SilcDList. Also, added
8333 `ident' field to SilcServerCommandPending structure to identify
8334 the reply and to call correct callback.
8336 Added silc_server_command_pending_check function to replace the
8337 corresnponding macro. The silc_command_pending list is not
8340 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8341 to set identifier to previously allocated Command Payload. It
8342 is used to set identifier for command when resending Command
8345 * Added silc_command_payload_encode_payload to encode Command
8346 Payload buffer from SilcCommandPayload structure.
8348 * Added silc_argument_payload_encode_payload to encode Argument
8349 payload buffer from SilcArgumentPayload structure.
8351 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8353 * Changed WHOIS command to support router connection on server side.
8354 The whois request is always sent to router unless the server is
8355 standalone server. After server has received the reply from the
8356 router will it send the reply to the client.
8358 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8359 broadcast received broadcast packet. The function is used only
8360 by router. The broadcast packet is always sent to the router's
8363 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8364 render given ID to printable string, for log files for example.
8366 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8368 * Made basic router to router connections working. At least they
8369 can now connect to each other but nothing really works the way
8370 they are supposed - yet.
8372 * Added new initiator token to RouterConnection configuration
8373 file in silcd/serverconfig.[ch]. It is used to tell whether we
8374 are the initiator to the remote router or whether we'll expect
8375 the other end to connect.
8377 * Moved registering of listener task to silc_server_init, hence
8378 the server starts listenning as soon as it is run, even if it
8379 does not have connections to other routers. Let's see how well
8382 * Changed default connection retry timeouts for more suitable in
8385 * Removed cipher and such arguments from silc_idlist_add_client
8386 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8387 Added new function silc_idlist_add_data to add the keys and stuff
8390 * Added SilcIDListData structure and added it to SilcClientEntry
8391 and SilcServerEntry as their first field in the structure. This
8392 way we can explicitly cast the ID entries to the SilcIDListData
8393 structure and get common data for the entries. In past, we had
8394 to first check what type of connection it is and then cast it to
8395 correct ID entry type. Now, we can directly cast the opaque
8396 pointer to the SilcIDListData (no matter what ID entry it actually
8397 is) and get the data needed.
8399 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8401 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8402 in some circumstances even if threre were timeout tasks, though not
8403 IO tasks, but tasks anyway. Now fixed.
8405 * Defined SilcServerConnection structure to hold connection specific
8406 stuff about directly connected servers and routers. The definition
8407 is currently in silcd/server_internal.h. I thought about having
8408 a bit more important role fro this struct but for now it is used
8409 only when connecting to other server (or router actually).
8411 * Added connecting retry support in server when connecting to
8412 router(s). The retry feature implement exponential backoff
8413 algorithm. Also, added SilcServerParams structure to hold default
8414 parameters for server. For now, it include these retry settings
8415 and are hard coded. After server is moded to be as Silc Server
8416 Library this structure will be more important.
8418 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Changed client librarys channel->clients table to SilcList and
8421 changed code accordingly.
8423 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8425 * Changed client's channel table to SilcList and changed code
8426 accordingly. Also changed SilcChannelClientEntry to include back-
8427 pointer to the channel so that client entry can use that structure
8428 as list as well and we have fast cross-reference to the channel.
8429 This change dramatically decreased the complexity of channel
8430 handling with client entry and vice versa (removed one extra
8431 loop when searching for channel entry from many functions).
8433 * Changed server->sim from table to SilcDList and changed code
8436 * NAMES command can now be used from user interface. It will show
8437 the user list on the channel, neatly.
8439 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8440 Code now saves realname of the user if it becomes available.
8442 * Renamed configure.in to configure.in.pre and made ./prepare
8443 script to automatically add correct version string to
8444 configure.in which it creates from configure.in.pre.
8446 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8448 * NAMES command reply now shows users mode with the nickname when
8451 * Moved silc_client_ch[u]mode[_char] functions from
8452 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8453 place sucks, they are utility functions and should be in some
8456 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8458 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8461 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8465 * Added TRQ (efficient deque and list library) into lib/trq. This is
8466 a very good list library that is currently used in the SILC. Defined
8467 SilcList API over the library because I didn't like the API very
8468 much. See lib/trq/silclist.h for the API and examples of how to
8469 use the API. Fixed various places in the code to use the new
8470 SilcList API. The SilcList is meant for lists that has a structure
8471 already defined as a list. It is not suitable to add just some
8472 context to the list (in TRQ, the context is the list actually).
8474 So, I defined SilcDList that can be used for the purpose where
8475 predefined list structure does not exit. This can be used as
8476 such list. Now some context just can be added to the SilcDList.
8477 Currently this list is not used in the SILC just yet, though there
8478 are a lot places where this can replace dynamically allocated
8479 tables and I will fix these places, later, to use SilcDList.
8480 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8481 and use TRQ internally).
8483 Also fixed some annoying warning messages that the original TRQ
8484 code generated. Also minor changes to TRQ's Makefile.in.
8486 * Added support for querying by Client ID to both WHOIS and
8487 IDENTIFY commands into server, as required by the protocol.
8489 * Removed method function pointers from SilcBuffer structure. They
8490 weren't used to anything and just increased the context size for
8491 no good reason. This change also made silc_buffer_alloc and
8492 silc_buffer_free functions inline functions.
8494 * Disabled command flooding detection support until it's fixed so
8495 that it accepts commands in but does not execute them more than once
8498 * Added silc_net_localhost(), to return local hostname, into
8499 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8500 that must be initialized before calling silc_client_init.
8502 * Added new function: silc_server_send_notify_on_channels to send
8503 notify messages to all channels client has joined. It is assured
8504 that the message is sent only once per client.
8506 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8507 lib/silcutil/silcutil.[ch] as silc_format function. The new
8508 function is generic and is used by server as well, not only by
8509 the logging routines.
8511 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8512 the provided version string was not acceptable. Added new function:
8513 silc_ske_check_version into lib/silcske/silcske.h. The function
8514 must be implemented by the application (client or server) and it
8515 does not reside in the SKE library. The function checks the version
8516 string remote end sent.
8518 * Added back pointers (to opaque context and to SilcSocketConnection)
8519 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8521 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8522 duplicate packet context structure.
8524 * Changed `notify' client operation to send same arguments as client
8525 receives from server except for ID's. ID's are mapped to correct
8526 ID entry and that is returned. Also, if channel entry is not sent
8527 by server but the notify is for channel the channel entry is sent
8528 to application (otherwise application doesn't know that it is for
8529 channel (library gets it from packet's Destination ID)).
8531 * Added silc_client_remove_from_channels into client library to
8532 remove a client from all channels it has joined to. Used when
8533 received SIGNOFF notify from server. Added also new function
8534 silc_client_replace_from_channels to replace old ID entry with
8535 new ID entry on all channels. Used when received NICK_CHANGE
8538 * Fixed ID Cache list handling in silc_idlist_get_client in
8539 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8540 to get (or query) client by ID.
8542 * Updated TODO list.
8544 * Added connection authentication status message defined by the
8545 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8546 support for these into the code in client and server side.
8548 * Added generic function silc_client_send_command to send any command
8549 with variable argument list. Application should use this function
8550 to send commands if the command functions provided by the library
8551 does not suite for the application's user interface needs.
8553 * Added new `failure' client operation. Application is notified about
8554 received failure packet if client is executing a protocol. In this
8555 case the protocol's execution has failed.
8557 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8558 is required by the protocol.
8560 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8561 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8564 * Added status flag to SilcSKE object to indicate realtime status
8565 of the SKE protocol.
8567 * Application receives now exactly same command reply arguments as
8568 the library receives from server. However, if ID is received the
8569 corresponding ID entry is returned to the application (eg. Client
8570 ID is mapped to correct SilcClientEntry entry and that is returned).
8571 Changed command_reply client operation due to this change.
8573 * Changed all ID's in commands and in command replys as ID Payloads.
8574 Change affected both client and server side codes.
8576 All ID's sent in SILC network (with execption of ID's in SILC
8577 Packet header) are sent in ID Payload to support variable length
8580 * Server now notifies nick changes and notifies all clients on
8581 the channels about the new nickname (about the new Client ID,
8584 * Implemented CMODE command to change channel modes. Supports all
8585 channel modes defined by the protocol specs except ban and invite
8586 lists. (Also, private channel key mode is supported but support for
8587 setting private channel key in client is missing, thus, this mode
8588 has no effect on client side (except that server requires that the
8589 client uses private channel key and normal channel traffic does not
8592 Also, invite mode works per se, but INVITE command does not work
8593 yet correctly, so you can set channel as invite only channel but
8594 inviting clients to the channel does not work (it is yet to be
8595 thought what's the best way to do it).
8597 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8598 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8599 Implemented CUMODE command to change user's mode on the channel.
8600 Supports all modes defined by the protocol specs.
8602 * Added NAMES command reply to return users modes on the channel.
8604 * Removed unnecessary and slow ciphers from lib/silccrypt.
8606 * Set SO_KEEPALIVE option to connection sockets by default.
8608 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8610 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8611 redefined the Notify Payload into protocol specs.
8613 * Added silc_id_payload_parse_id to get ID directly from raw
8616 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8618 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8619 accept searching by Client ID as well.
8621 * Added support for LEAVE and SIGNOFF notify types in client library.
8623 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8624 to parse ID Payload from raw data.
8626 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8628 * Added flags parameter into silc_ske_assemble_security_properties
8629 function in lib/silcske/silcske.[ch].
8631 * Changed notify client operation to fit better for notify messages
8632 sent by server. The notify payload received from server is now
8633 passed to the application (after parsing it to SilcNotifyPayload).
8634 It is application's responsibility to retrieve the arguments
8635 from the payload and show the message the way it wants. The message
8636 sent by server is implementation specific.
8638 * Changed public keys to comply with the protocol specification.
8639 Old public keys are not supported anymore and are not compatible.
8641 * Removed nickname from Channel Payload as the latest draft removed
8642 it. The client must resolve the nickname from the NAMES command
8643 reply received when it joined the channel.
8645 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8647 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8649 * Fixed some errors in protocol specification drafts.
8651 * Created lib/silccore/silcnotify.c to implement Notify Payload
8652 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8653 generic payloads described by protocol specifications. The file
8654 includes implementations for ID Payload and Argument Payload.
8656 * Changed Command Payload implementation to use the new Argument
8657 Payload. Changed command_xxxx_payload to command_payload_xxxx
8658 to comply with SILC coding conventions.
8660 * Added suppport for Argument Payload handling in Notify Payload
8661 implementation as protocol requires it. Added the new support
8662 into server and client lib as well.
8664 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8666 * Added support for multiple nicknames on same channel. [n] is
8667 added locally to the nickname if there are more than one same
8668 nicknames on the channel.
8670 * Server now sends all nicknames that matched WHOIS request.
8671 Client also shows the list received from server.
8673 * Added TOPIC command to client side. User can now set and show
8674 current topic on channel.
8676 * Added MOTD command to client and server. Also, server sends the
8677 motd when client connects to the server.
8679 * Changed version strings to comply ISO 8601.
8681 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8683 * Fixed protocol error handling in client library. It should now
8684 cope even if the SKE fails for some reason.
8686 * Made new protocol specification drafts for submitting to IETF.
8688 * Implemented TOPIC command to server in silcd/command.c.
8690 * Added two new notify types into lib/silccore/silcnotify.h:
8691 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8692 notify nickname change and topic setting/change on a channel.
8694 * API change of command_reply operation in client library. The
8695 application gets now the status type received from server as well.
8697 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8699 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8701 * Cras fixed and optimized the packet handling even further and
8702 it should work now. Minor change to the prototype of function
8703 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8705 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8707 * Added new function into lib/silcutil/silcschedule.[ch]:
8708 silc_schedule_with_fd to select() a specified fd. The function
8709 returns after timeout expires or data arrives or goes. The
8710 function is used by packet routines to wait that all data is
8711 received from network.
8713 * Fixed data reading from network in lib/silccore/silcpacket.c.
8714 The code now assures that all data is read from the fd and then
8715 continues packet processing. This was a bug fix since the code
8716 used to drop some data in some circumstances.
8718 * Added new function into lib/silcclient/client.[ch]:
8719 silc_client_start_key_exchange to start key exchange after
8720 connection has been established to server. The code internally
8721 now uses this funtion but its main purpose was to provide it
8722 for applications that perform their own connecting. After
8723 application has created a connection it merely calls this
8724 function to start the key exchange between client and server.
8725 The library takes care of everything else after that.
8727 Updated also lib/silcclient/README to explain the usage of
8730 * Do not send to application information that connection has
8731 been established. Application gets notified it by connect
8734 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8736 * Applied cras's patch to add silc_schedule_one function. The
8737 function runs scheduler once and returns.
8739 * Fixed the scheduler after cras messed it up. The timeout
8740 handling works now as it's supposed to work.
8742 * Added into lib/silccore/ silcnotify.h to include notify
8743 message types support. Changed silc_server_send_notify*
8744 functions, in server.[ch], to support those new notify types.
8745 Added the support for the notify types into client library,
8746 as well. Added new notify client operation into ops.h in
8749 * Changed silc_server_packet_send_to_channel to send normal
8750 packets instead of just channel message packets. The function
8751 is now used to send the notify packets to channels. It is not
8752 used to send channel message packets anymore, as server never
8755 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8756 va_arg()s as it seems to require it nowadays. I guess, if SILC
8757 is compiled with older va_arg() the new code should work anyway.
8759 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8761 * Splitted core library. Core library (lib/silccore) includes
8762 now only SILC protocol specific core (and common) components.
8763 Created new utility library (lib/silcutil) that includes more
8764 generic purpose stuff. The stuff for util library was taken
8765 from the old core library. This was minor and easy split.
8767 * Created SILC Client Library (lib/silcclient) that includes
8768 implementation of the SILC client without user interface. This
8769 was major move from silc/ directory. The code has been changed
8770 so that it is transparent towards the user interface. The
8771 silc/ directory includes now the same user interface as before
8772 and it uses the new client library. Read lib/silcclient/README.
8773 Basicly, the client library performs everything else related
8774 to SILC except user interface handling. Also, configuration
8775 files are considered to be part of user interface and library
8776 does not handle them.
8778 This change also changed a lot of structures, function naming etc.
8779 Most important change was that SilcClientWindow object was
8780 renamed to SilcClientConnection in the client library. Created
8781 also new file lib/silcclient/ops.h. Also added new files
8782 silc/local_command.[ch] and silc/client_ops.[ch].
8784 All these changes were made to make it easier for user interface
8785 designers to create what ever user interface for the SILC client
8788 It is also expected that the server will be moved to lib
8789 directory as well and SILC Server Library will be created;
8790 sometimes in the future.
8792 * Removed Local commands from lib/silccore/silccommand.h as
8793 they are application specific and new client library does not
8794 handle any of those anymore.
8796 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8797 old client implementation in silc/.
8799 * Added support for callback functions in SILC_LOG_* macros.
8800 Application can now set its own callbacks that will be called
8801 instead of using the default functions that will always print
8802 the debug messages to stderr (or stdout). Also, debugging can
8803 now be disabled by setting silc_debug to FALSE and re-enabled by
8804 setting it to TRUE. Note, that logging will still work even
8805 if debugging is disabled.
8807 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8808 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8809 silc_log_reset_debug_callbacks.
8811 * To enable debugging in silc client one must give now -d
8812 option on command line.
8814 * Changed silc_schedule_init to automatically allocate task queues
8815 if they are not allocated before calling it.
8817 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8819 * Added GMP 3.1 into math library.
8821 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8823 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8824 a channel in SILC network. The packet is used by servers and
8825 routers to notify other routers that user has left a channel.
8826 This little feature was missing until now. Added the feature
8827 to protocol specification as well.
8829 Added functions: silc_server_send_remove_channel_user and
8830 silc_server_remove_channel_user into server.[ch].
8832 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8833 lib/silccore/silcpacket.h. However, they are not implemented
8836 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8838 * Fixed joining to a channel and sending channel messages
8839 between server and router. The channel message sending should
8840 now work inside a cell.
8842 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8844 * Fixed the private message sending between server and router.
8845 The private message sending should now work inside a cell.
8847 * Added silc_server_replace_id into server.[ch] to replace
8848 existing ID in the SILC network.
8850 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8851 and silc_idlist_replace_server_id into idlist.[ch] in server.
8853 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8855 * Fixed the server to server connections. Server can again now
8856 connect to router. Router to router connections probably does
8859 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8861 * Added dynamic protocol registering support. Now protocols can
8862 registered and unregistered on the fly. Patch by cras.
8864 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8866 * Added lib/contrib directory to hold routines that some platforms
8867 don't have but are needed by SILC.
8869 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8870 into lin/contrib to provide getopt() and getopt_long() for
8871 those who don't have it.
8873 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8875 * Added AWAY command to client. When away message is set and
8876 client receives a private message packet the client automatically
8877 replies to the sender with the away message.
8879 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8880 bug seemed to be the cause of recent problems when compiling
8883 * Added version detection support to SKE protocol specification
8884 and added the new changes to the SKE implementation as well.
8885 There were other minor changes in the SKE protocol as well.
8887 Many changes in lib/silcske/silcske.[ch] and in
8888 lib/silcske/payload.[ch].
8890 * Added ^U functionality, clear input line. Patch from cras.
8892 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8894 * Mainly small bugfixes on core library. Fixed some debugging
8895 logging and buffer overflow in silclog.c.
8897 * Updated config.sub and config.guess on the distribution tree.
8899 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8901 * Added command lagging support in server. Client may execute
8902 commands now only once in two seconds.
8904 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8906 * Optimized packet reception. MAC computation and checking is now
8907 also more optimized. A lot previously duplicated code is now
8908 used as generic by both client and server.
8910 * Fixed key pair generation in clientutil.c
8912 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8914 * Added into lib/silccore/silcbufutil.[ch] new function;
8915 silc_buffer_realloc.
8917 * Moved generic packet sending/encryption functions to
8918 lib/silccore/silcpacket.[ch] from client and server. Some
8919 rewriting of the functions.
8921 * Moved all generic packet reception/decryption functions to
8922 lib/silccore/silcpacket.[ch] from client and server. The
8923 packet processing is now much cleaner in both client and server.
8924 These were major changes in both client and server.
8926 * Created many common functions in server to do packet sending.
8927 Previously code were duplicated a lot, this has been removed
8930 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8932 * Rewrote major parts of the ID cache system. Don't know
8933 whether it is better now or not but at least the API is more
8936 * Major rewrite on ID cache stuff on client because of the ID
8937 cache API changes. Added idlist.c to client.
8939 * Also major rewrite on ID cache stuff on server as well.
8940 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8941 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8942 in hand, instead they are all put into the ID cache system now.
8943 All server_idlist_* routines uses ID cache now instead of
8944 traversing its own lists (those lists does not exist anymore).
8945 SilcIDList though still exists. Also, SilcXXXEntry's are
8948 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8950 * Finally made the SKE implementation compliant to the protocol
8951 specification. All mp integers are now binary encoded as
8952 opposed being HEX encoded.
8954 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8957 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8958 functions: silc_[encode/decode]_pem. Also added function
8959 silc_encode_pem_file to PEM encode with newlines ('\n') for
8962 * SILC public keys are now encoded either PEM or binary. Same
8963 option is for private keys as well. By default private keys
8964 are binary encoded and public keys PEM encoded. Silly HEX
8965 encoding were removed.
8967 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8968 function to create fingerprints.
8970 * Fixed a bug in SHA1; does not change the original data anymore.
8972 * Partly implemented INFO command on client and server side.
8973 Fixed CLEAR command. Changes to SERVER command; show current
8974 server(s) when giving command without arguments. Added
8975 VERSION command to client.
8977 * Added check to server that unregistered connections cannot
8978 execute commands (unless it is specificly allowed).
8980 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8982 * Fixed screen refresh.
8984 * Fixed channel joining bug from client. On some circumstances
8985 client tried to join to a channel it had already joined.
8987 * Added public key verification process into client's protocol.c.
8988 The client now verifies the public key from user and saves
8989 it into ~./silc/serverkeys/ directory.
8991 Added into: clientutil.[ch]: silc_client_verify_server_key.
8993 * Changed SKE protocol's silc_ske_initiator_finish function
8994 to accept callback function that verifies the received public
8995 key. Removed old silc_ske_verify_public_key function.
8997 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8999 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9000 silc_pkcs_private_key[_data]_set.
9002 * Made the password and public authentication more cleaner in
9003 server's protocol.c.
9005 * Removed historic and obsolete protocol `channel_auth' from
9006 both client and server.
9008 * Removed wrong way of sending command status messages from
9009 server to client in server's command.c. The old way violated
9010 protocol specification.
9012 Changes to silccore/silccommand.[ch]: removed
9013 silc_command_encode_status_payload -> not needed anymore,
9014 changed silc_command_encode_payload_va to accept extra
9015 argument on variable argument list. The argument type must
9016 now be provided to the function. Also, added new function:
9017 silc_command_encode_reply_payload_va which is same as
9018 normal command_encode_payload_va except command status type
9019 is provided as extra argument.
9021 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9023 * Added ~./silc directory handling. The directory includes the
9024 public and private keys for the client.
9026 Added silc_client_check_silc_dir, silc_client_create_identifier
9027 and silc_client_load_keys.
9029 * Implemented SILC protocol compliant public key. Added public
9030 and private key saving to and loading from files.
9032 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9033 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9034 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9035 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9036 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9038 Implemented: silc_pkcs_save_[public/private]_key[_data] and
