60 as part of Requested Attributes in WHOIS command. Affected
61 file lib/silcutil/silcvcard.[ch].
63 Fri Oct 11 23:52:17 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
65 * Some strncat -> silc_strncat changes our the core and
68 * Added SILC_SKE_STATUS_SIGNATURE_ERROR and OUT_OF_MEMORY
69 errors. Added better error printing to SKE library.
70 Affected files lib/silcske/silcske.c, silcske_status.h and
73 * Save the PKCS key length even if only private key is set to
74 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
76 * Fixed the usage of silc_pkcs_get_key_len since it returns the
77 length in bits not in bytes. Affected files are
78 lib/silcske/silcske.c, lib/silccore/silcauth.c and
81 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
83 * Added silc_attribute_payload_encode_data to directly encode
84 the data into the attributes buffer. Renamed function
85 silc_attribute_payload_parse_list to silc_attribute_payload_parse.
86 Affected files are lib/silccore/silcattrs.[ch].

93 the Requested Attributes from the client. Fixed memory leak
94 in client entry freeing. Affected files silcd/server_query.c
97 * Added Requested Attributes support into SILC Client Library.
98 It is not able to send requested attributes in WHOIS command,
99 and also receive and process requested attributes. Added
100 silc_client_attribute_[add|del] and silc_client_attributes_get
101 functions. Added also `ignore_requested_attributes' to the
102 SilcClientParams to not use attributes in client. Affected
103 files are lib/silcclient/command.c, client_attrs.[ch],
104 silcclient.h, client_internal and client.[ch].
106 * Changed the silc_client_get_client_by_id to support Requested
107 Attributes, it takes them as argument now. Affected file
108 is lib/silcclient/silcclient.h, and idlist.c.
110 * Added -details option to WHOIS command in Irssi SILC Client
111 to support the requested attributes. By default it requests
112 all attributes. Affected file lib/silcclient/command.c and
113 irssi/doc/help/in/whois.in.
115 Tue Oct 8 17:58:28 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Add also SERVICE attribute for server-constructed attribute
118 data. Also digitally sign the attributes and add

120 silcd/server_query.c.
122 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
124 * Changed the silc_attribute_payload_encode to support list
125 of attributes (function may be called several times to add
126 a new attribute). Removed the silc_attribute_payload_encode_list
127 function. The encoding function now also automatically encodes
128 the data, so the caller does not need to do that. Affected
129 files lib/silccore/silcattrs.[ch].
131 * Added support for replying on behalf of the user to the
132 Requested Attributes in WHOIS command in the server. Affected
133 file silcd/server_query.c.
135 * SILC_NOT_IMPLEMENTED macro use SILC_LOG_INFO now instead of
136 SILC_LOG_DEBUG. Affected file lib/silcutil/silclog.h.
138 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Don't swtich to become primary router if we are backup if
141 decryption error has occurred. Affected file silcd/server.c.
143 * Fixed a bug in backup router IP address comparison in
144 silc_server_backup_get.
146 Save now also the port of the server/router and use that
147 in comparison as well. Affected file silcd/server_backup.c.
149 * Normal server now reconnects to backup router automatically
150 if connection is lost to it. Affected file silcd/server.c.
152 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
154 * If packet processing fails (like integrity check fails)
155 the connection is closed now. Affected files are
156 lib/silccore/silcpacket.c and silcd/server.c.
158 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

166 * Rewrote WHOIS, WHOWAS and IDENTIFY commands in the server.
167 Added server_query.[ch] which provides one interface for
168 querying information using all three commands.
170 * Changed all "typedef unsigned char" in core library to
173 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

182 * Resumed client packet handling from server put the resumed
183 client on wrong list on router and caused the client not
184 be present on the network anymore. Now fixed to put the
185 client to correct list. Affected file silcd/packet_receive.c.
187 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
189 * Various cleanup in error message output in config parsing code
190 and in server init code. Fixed error log files containing
191 too many newlines ('\n') in some situations. Affected files are
192 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
194 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Use the reverse lookupped hostname in client internals
197 instead of one user provided us as remote server name.

200 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
202 * Added 'app_context' to silc_schedule_init. It is an
203 application specific context that is delivered to application
204 in task callback functions. Affected files are
205 lib/silcutil/silcutil.[ch].
207 * The hb_context in SilcSocketConnection is not freed
208 automatically anymore (application must free it). Freeing
209 it automatic is inconsistent. Affected files are
210 lib/silcutil/silcsockconn.[ch].
212 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Added support for removing explicitly added client connections
215 in rehash and closing the client connections if they were
216 unconfigured in the rehash. Affected file silcd/server.c.
218 * Added support for aborting automatically pending commands
219 that never receives the reply (to avoid memory leaks).
220 Added also silc_server_command_pending_timed to set the
221 specific timeout for pending command. Affected files are
222 silcd/command[_reply].[ch].
224 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
225 specs and lib/silccore/silcstatus.h.
227 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
229 * Changed the silc_get_time to accept time value as argument
230 or if zero is sent return current local time. Affected
231 file lib/silcutil/silcutil.[ch].
233 * Added STATS command to client library and Irssi SILC client.
234 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
236 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
238 * Assure that channel key is set before sending it. May
239 crash server otherwise. Affected file silcd/packet_send.c.
241 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Assure that endless loop cannot happen with detached client
244 resolving on normal server. Added idlist status
245 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
246 silcd/idlist.h and silcd/packet_receive.c.
248 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
250 * Incoming file transfer request cannot use same session as
251 the sending session. This can happen when sending file to
252 yourself. Crashed the client on quit. Affected file
253 lib/silcclient/client_ftp.c. Bug #24.
255 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Implemented the draft-riikonen-precense-attrs draft and
258 the Attribute Payload into the lib/silccore/silcattrs.[ch].
260 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Distribute the SERVER_SIGNOFF notify also to local backup
263 routers from the primary router. The backup router may not
264 have the signing of local server directly connected and need
265 to know about the signoff. Affected file silcd/server_util.c.
267 * Use the primary router as the origin of the locally connected
268 server when it is disconnecting from the backup router since
269 that's where it really is coming from. Now the clients from
270 the disconnecting server are removed correctly and "shadow"
271 clients are not left to the backup router. Affected file
274 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
276 * If normal server is standalone and found existing but disabled
277 channel, do not re-create the channel since it creates
278 duplicate same channels. Affected file silcd/server.c.
280 * Added anonymous client connections support to server. New
281 "anonymous" configuration option to ConnectionParams section
282 added. If set to true, the username and hostname information
283 of the client will be scrambled and anonymous user mode is
284 set automatically to the user. Affected files are
285 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
287 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
289 * In JOIN notify handling, mark that the cache entry of the
290 client cannot be expired. Can cause crashes on normal
291 server (asserts client->channels). Affected file is
292 silcd/packet_receive.c.
294 * From now on distribution versions are used as protocol versions
295 instead of by default using the Toolkit base version as protocol
296 version. Affected file prepare.
298 * Do not set the locally resolved hostname for local client
299 entry but take what server sends. This way the real hostname
300 is showed in WHOIS for yourself. Affected file is
301 lib/silcclient/idlist.c and lib/silcclient/client.c.
303 * Resolve local info with IDENTIFY when connecting to server.y
305 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
307 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
308 for implied search (not needed on platforms which has native
309 pthreads library). Use --without-pthreads to disable threads.
310 Affected file is configure.in.pre
312 * Fixed --with-iconv on platforms which need to bypass (broken)
313 native iconv(). Affected file is configure.in.pre
315 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Moved -C option parsing in Irssi SILC client at same time
318 as other options. The UI was initialized earlier and caused
319 problems on command line. Bug #16. Affected file is
320 irssi/src/silc/core/silc-core.c.
322 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
324 * Added global variable silc_log_timestamp that tells silclog
325 wether to print or not the timestamp in the logging files.
326 Affected file lib/silcutil/silclog.[ch].
328 * Added silcd configuration option Timestamp in the Logging
329 section. Affected file silcd/serverconfig.[ch],
330 doc/example_silcd.conf.in.
332 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Fixed fingerprint checking to check for entirely empty
335 fingerprint instead of two first bytes when determining
336 if it is set. Bug #18. Affected file silcd/command.c.
338 * Fixed duplicate PKCS name registering to not allow it.
339 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
341 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
343 * Conditionalize non-gcc compiler optimizations for various
344 platforms, enable those commented out. Cleanups.
345 Affected file lib/silcmath/mpi/configure.in
347 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
349 * silc_rng_exec_command() left zombie processes if command
350 didn't generate any output. Affected file
351 lib/silccrypt/silcrng.c
353 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
355 * Rewrote iconv checking, introduce --with-iconv for systems
356 which rely on libiconv. Check if iconv() provided by libc
357 is good enough, otherwise demand libiconv. Affected file
360 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
362 * Search for ldopen() also in libc. This enables SIM support
363 on *BSD systems. Based on patch from Alex Zepeda. Affected
364 file configure.in.pre
366 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
368 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
369 This fixes prepare on *BSD systems. Affected file
372 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
374 * More fixed for not having purge timeout for global clients
375 that are on channel. Affected files silcd/command_reply.c
378 * Fixed the rekey protocol to work with backup router connections.
379 Rekey packets are now allowed on disabled connections as
380 well. Affected files silcd/packet_send.c and server.c.
382 * Do not switch to be as backup router when shutting down and
383 closing the primary connection. Affected file silcd/server.c.
385 * Fixed memory leaks in backup router deleting. Added
386 silc_server_backup_free to free all data during shutdown of
387 server. Affected files silcd/server_backup.[ch].
389 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Do not process commands if the sock->user_data is NULL.
392 Affected file silcd/command.c.
394 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
396 * Fixed buffer overflow and security problems (loosing bits
397 in CFB encryption) in SILC RNG. Problems reported by
398 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
400 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
402 * Added yet more checks that client is not expired on global
403 list if it is on channels. Affected file is
404 silcd/command_reply.c.
406 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Merged c0ffee's MIME signal patch which adds support for
409 sending also MIME messages in Irssi SILC Client, and handling
410 received MIME messages in a signal (and perhaps doing something
411 to non-textual MIME messages).
413 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Fixed pending command deletion in server and client library
416 to check the whole list instead of breaking after first found.
417 The affected files are silcd/command.[ch] and
418 lib/silcclient/command.[ch].
420 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
422 * Return NO_SUCH_CHANNEL error in USERS for channel that is
423 secret or private, otherwise it's possible to find out
424 whether a secret channel exists or not. Affected file
427 * If CMODE change fails during the mode setting, assure that
428 the old mode mask is set for the channel back. Affected
429 file silcd/command.c.
431 * Fixed passphrase saving on +a channel on normal server
432 after successful JOIN command. Affected file silcd/command.c.
434 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
436 * Remove server/router operator privileges in DETACH command,
437 since it's possible to resume to server where these
438 privileges would not be allowed for the client. Affected
439 file silcd/command.c.
441 * Do not set to wait for backup in rehash of the server.
442 Affected file silcd/server.c.
444 * Do not check listener sockets when counting how many
445 socket connections we have. Affected file is
448 * Do not announce disconnected clients that are remaining
449 in history (for WHOWAS). This is because SIGNOFF notify
450 for these has been sent earlier already. Affected file
453 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Buffer overflow with CUMODE command's mode->mode character
456 conversion. Reported by Ville Räsänen. Affected file
457 lib/silcutil/silcutil.c.
459 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Allow heartbeat packets to go disabled connections anyway.
462 Affected files silcd/server.c and silcd/packet_send.c.
464 * Do not broadcast New Channel packets with List flag set
465 in the packet to backup routers. The router must check
466 for the correctness of the packets before sending them.
467 It is possible that router will have enforce Channel ID
468 change and this would cause desync in the backup router.
469 Affected file silcd/packet_receive.c.
471 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
472 are handled in list parsing. They are not list packets
473 anymore. Affected file silcd/packet_receive.c.
475 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Stop waiting for backup router through the timeout, not
478 directly after backup router has arrived. Affected file
481 * Do not re-create channel keys and send them when removing
482 clients in server shutdown. Affected files are
483 silcd/server_internal.h and silcd/server_util.c.
485 * Notify distribution to backup routers was missing from
486 the silc_server_send_notify_dest function which caused
487 desyncing problems with backup router. Affected file is
490 * The client's channel removing was working wrong on
491 backup router. It assumed that it doesn't know global
492 information but backup router does know. For this reason
493 it could remove channel when it wasn't supposed to do that.
494 Affected file silcd/server.c and silcd/server_util.c.
496 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
498 * Stop for a couple seconds after badkup router has become
499 primary router. Affected file silcd/server.c.
501 * Added silc_server_remove_servers_by_server, which is used
502 to remove servers originated from some other server. Also
503 clients of those servers can be removed too. Affected file
504 silcd/server_util.[ch].
506 * When removing clients after a server has signed of remove
507 also all servers behind that server (unless they are known
508 to be available locally), and send SERVER_SIGNOFF for each
509 of the server separately. Also the signed off clients are
510 sent now separately per signed off server. The affected files
511 are silcd/server.c and silcd/server_util.[ch].
513 * All servers added with silc_idlist_add_server must always
514 have both "router" and "connection" pointers set. Otherwise,
515 bad server entries may be left around in the cache.
516 Affected file silcd/command_reply.c.
518 * Do not create the channel key in NEW_CHANNEL packet
519 processing if the channel is empty. Affected file
520 silcd/packet_receive.c.
522 * Completed backup router support for standalone routers.
523 Supports also servers in the cell that do not use the backup
526 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
528 * Fixed a bug in silc_string_regexify which did not add '^'
529 at the start of each string, and thus the matching was
530 not explicit. For example ban list iikone@*!*@* would
531 match also "priikone", which is wrong, it would have to be
532 *iikone@*!*@* to match also "priikone". Affected
533 file lib/silcutil/unix/silcunixutil.c.
535 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Enable all local server connections before updating client
538 caches when we've become backup router. Otherwise, signoff
539 packets may not reach the clients. Affected files are
540 silcd/server.c and silcd/server_util.[ch].
542 * Fixed a bug in version string parsing which could crash
543 the program with specially formatted version string.
544 Bug reported and patch provided by Ville Räsänen. Affected
545 file lib/silcutil/silcutil.c.

556 NICK_CHANGE arrived for client entry we are resolving
557 currently. Affected file lib/silcclient/client_notify.c.
559 * Call the sconn->callback completion even if error had
560 occurred. Start reconnecting always if connection to
561 primary router fails during backup router protocol.

578 silcd/server_backup.c.
580 * Fixed the updating of client information after backup
581 resuming protocol is over; update all except local clients
582 to the new primary router. The affected file is
585 * Added support for closing active connections in rehash
586 that were unconfigured by the user. Supports currently

590 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
592 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
594 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
595 is NULL since seems that on some platforms NULL is allowed
596 and on some it's not. Fallback encoding is used instead.
597 Affected file lib/silcutil/silcstrutil.c.
599 * Fixed statistics updating for incoming server connection
600 which could cause problems when re-connecting. Affected
603 * Preliminary backup router support for standalone router

626 notify only after it's resolved so that all notifys are
627 handled in same order as received from the server.
629 Added similar resolver check to channel entries. Every
630 notify that cause resolving of any information that affects
631 channel entry marks the channel entry in waiting state.
632 After whatever resolving is over the waiters are signalled
633 and only then the notifys are handled in the same order
634 as delivered from the server.
636 Affected files are lib/silcclient/idlist.[ch], and
639 * Fixed KILLED notify handling in normal server. Affected
640 file silcd/packet_receive.c.
642 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
643 is locally connected, or was locally connected (but may

681 removing from channels (theoretically at least). Affected
682 file silcd/server.c and silcd/server_util.c.
684 * Free the client data too when resuming is not successful.
685 Affected file silcd/packet_receive.c.
687 * Merged some code from c0ffee's silc-plugin. Affected files
688 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
690 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
691 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
692 to the primary router connection, the other one returns
693 TRUE if packet must be broadcasted to network.
695 * All notifys that are destined to primary router (to network)
696 are now automatically sent to backup routers even if the
697 router is standalone (and has backup router). Affected files
700 * Added --without-irssi and --without-silcd configuration
701 options for disabling the compilation of these applications.
702 Affected file configure.in.pre and prepare.

728 command reply from router, on normal server. Otherwise
729 joinig +a channels from normal server is not possible.
730 Affected file silcd/command.c.
732 * Fixed a bug in TOPIC_SET notify handling. The notifier
733 may be other than client too, like server or channel.
734 It expected it to always be only client and ignored the
735 notify. Affected file silcd/packet_recieve.c.
737 * Removed some (unnecessary) debug printing from
738 lib/silccore/silcid.c and lib/silccore/silcargument.c.
740 * Do not force CMODE_CHANGE when server is announcing new
743 Router announces stuff only after server reannounces channel
744 after CHANNEL_CHANGE notify.
746 These fixes optimizes the announcing procedure, and perhaps
747 fixes some problems too. Affected file silcd/packet_receive.c.
749 * Fixed SERVER_SIGNOFF sending to local clients. It was
750 totally broken and sent the notify to all local clients,
751 instead of only to those that was on same channel as the
752 signing off clients. Affected file silcd/server_util.c.
754 * Added -D option to server. It can be used to give debug
755 level. The levels are from 0 - 99, and are predefined for

1363 * Redefined the Status Payload to include now two 8 bit fields,
1364 instead of one 16 bit field. This now makes it possible to
1365 send list of errors. Updated the protocol specs and the code
1366 in core library, client library and server. Protocol TODO #1.
1367 Affected files are lib/silccore/silccommand.[ch],
1368 lib/silcclient/command_reply.[ch], silcd/command.c,

1371 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1373 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1374 must be handled by the application and should tell the application
1375 that an error message was already printed, and it should print the
1376 config coords (line, filename, ...). Affected files are
1377 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].

1398 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1400 * Added STATS command to the protocol after all, to return
1401 various statistical information about the network. It can
1402 be used by clients to retrieve statistical information, and
1403 servers may use it to to fetch cell and network wide
1404 statistics from router. Updated the protocol specs and
1405 implemented it to the server. Protocol TODO #16.
1406 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1411 * The LIST command reply in client libary now adds new channel
1412 entry if the returned channel doesn't exist yet in cache,
1413 and returns the channel entry to the application in the
1414 command_reply client operation. Affected file is
1415 lib/silcclient/command_reply.c.
1417 * Changed the channel message payload's MAC generation to
1418 include the IV in the MAC as well. This way all relevant
1419 parts of the channel message payload are authenticated also
1420 with the channel message MAC (and not only by packet MAC).
1421 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1422 Affected file is lib/silccore/silcchannel.c.
1424 * Fixed the SKE to save the remote version, since the
1425 silc_ske_parse_version mistakenly checked wrong version,

1496 generic reply to a generic request (REQUEST flag), and
1497 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1498 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1499 to define the payload for DATA flag. Added the flags to
1500 the implementation. Protocol TODO #9. Affected file is
1501 lib/silccore/silcchannel.h.
1503 Changed the client library to return the message length

1547 * Some client implementations quit network by doing first LEAVE
1548 and then immediately SIGNOFF (like Bombyx). We now do check
1549 after a short time after LEAVE notify and check whether the
1550 client is still valid after LEAVE, and if not we remove it from
1551 cache. Affected file is lib/silcclient/client_notify.c.
1553 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1582 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1584 * Fixed the Irssi SILC Client to use the silc_get_username and
1585 silc_get_real_name insted of glib routines since the glib
1586 routines only corrupt stack. Fixes the Irssi SILC to work in
1587 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1589 * Fixed the Irssi to not use g_get_home_dir since it crashes
1590 or returns garbage on cygwin and corrupts stack. Added function
1591 get_home_dir to Irssi routines. Affected files are
1592 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1594 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Made some structure optimizations. SFTP memory FS MemFSEntry
1597 entry structure. Optimized SilcTask structure. Optimized
1598 SilcPacketContext structure.
1600 Affected files lib/silcsftp/sftp_fs_memory.c,
1601 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1603 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * And yet again reverted back the config thing since Johnny
1606 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1609 * Fixed memory leaks from config object. Affected files are
1610 silcd/serverconfig.[ch].
1612 * Added support for adding new connections to the server in rehash.
1613 After rehash they take effect.
1615 Added support for changing the maximum allowed connections in
1616 rehash. The number can grow but going smaller is not supported.
1618 Added function silc_server_num_sockets_by_remote to the
1619 silcd/server_util.[ch].
1621 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1623 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1625 * Added preliminary checking during config parsing for a valid
1626 public/private key and removed further checks in the code.
1627 Affected files are silcd/serverconfig.[ch], server.c.
1629 * Moved functions silc_server_drop() and silc_server_daemonise()
1630 from server.c to silcd.c since they are stricly related to
1631 the application activity.
1633 * Reverted a small part of the automatic ref/unref since
1634 it caused a double unref in some situations. Affected
1635 files are silcd/silcd.[ch], server.c, serverconfig.c.
1637 * Added some .cvsignore files in the lib directory.
1639 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1641 * Fixed silc_net_gethostbyaddr to correctly resolve by
1642 address. Affected file lib/silcutil/silcnet.c.
1644 * Fixed the notify relaying to client. The HMAC to be used
1645 with relayed packets ws wrong and caused decryption failure
1646 at the client end. Affected file is silcd/packet_receive.c.
1648 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1650 * Created new branch silc_protocol_1_0_branch.
1652 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1654 * Changed the silc_server_config_* routines to be SilcServer
1655 independent. They are now officially application specific code
1656 and not part of generic server implementation. Affected files
1657 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1659 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1661 * Added automatic referencing of config context in the
1662 silc_server_config_alloc, and automatic unreferencing in the
1663 silc_server_config_destroy. Affected files are
1664 silcd/serverconfig.[ch], silcd/silcd.c.
1666 * Fixed the silc_log_quick handling in the logging routines.
1667 It didn't log quickly when it was TRUE. Affected file is
1668 lib/silcutil/silclog.c. Also the flush delay was set even
1669 if it was 0 in config file. Affected file is
1670 silcd/serverconfig.c.
1672 * Added support for changing key pair of the server in rehash.
1673 Affected file silcd/server.c.
1675 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1677 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1678 too early, before getting the channel entry. Affected file
1679 is silcd/packet_receive.c.
1681 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1683 * Added functions silc_server_config_[ref/unref], these are used
1684 to prevent that the config object is destroyed.
1686 No longer directly affect global variables silc_log_quick and
1687 silc_log_delay, they are first cached inside the config object
1688 and then applied with silc_server_config_setlogfiles().
1690 silc_server_config_set_defaults() is now internal to
1691 serverconfig.c, there are no reasons to show this internal stuff
1694 Affected files are silcd/serverconfig.[ch].
1696 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1697 fprintf's to stderr, since some code may be executed again after
1698 the server went into the background. Affected files are
1701 * Added rehash support. Added function silc_server_rehash() that
1702 will perform all the basic tasks of the rehashing procedure.
1704 * Added command line option `-x, --hexdump'. This will enable the
1705 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1706 The option `--hexdump' implies `--debug'.
1708 * Fixed a bad bug in the logging APIs (silcutil library) where
1709 the application would crash after calling silc_log_reset_all().
1711 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed the KICKED notify handling in client library to
1714 correctly remove the channel and all entries from the
1715 channel when I was kicked. This bug crashed the client.
1717 Fixed yet another but in KICKED notify handling to remove
1718 the kicked client correctly from the channel.
1720 Affected file is lib/silcclient/client_notify.c.
1722 * Fixed a minor bug in looking up correct client entry
1723 in KICKED notify in server. Affected file is
1724 silcd/packet_receive.c.
1726 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1727 sources correctly to distribution. Fixes --with-gmp option.
1729 * Removed the manual rehashing from ID Cache, and changed it
1730 to use the SILC Hash Table's auto rehash feature. Affected
1731 file is lib/silccore/silcidcache.c.
1733 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1735 * Fixed a bug in the silc_client_nickname_format function that
1736 handles the multiple same nickname formatting. Two clients
1737 with same nickname caused problems after the first one left
1738 and rejoined. It didn't format the nickname correctly.
1739 Affected file is lib/silcclient/idlist.c.
1741 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1743 * Don't change the topic if olod topic is same as new one.
1744 Affected file is silcd/packet_receive.c.
1746 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Added cross-reference support to the SILC Documentation
1749 generator. All types across all HTML files are now cross-
1750 referenced. Affected files util/robodoc/generator.c and
1751 scripts/silcdoc/silcdoc.
1753 * Added file lib/silcutil/silctypes.h to include all the
1754 arithmetic type definitions and some macros. Removed
1755 includes/bitmove.h and moved macros to silctypes.h.
1757 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1761 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1763 * Added `type' argument to silc_id_payload_parse_id function which
1764 now returns the type of the ID to the sent pointer. Affected
1765 file is lib/silccore/silcid.[ch].
1767 * Added check for CMODE_CHANGE notify type that mode change is
1768 allowed by the sender. Affected file silcd/packet_receive.c.
1770 * Added check for CUMODE_CHANGE notify type that mode change is
1771 allowed by the sender. Affected file silcd/packet_receive.c.
1772 Added the ID type as CUMODE_CHANGE notify type as argument
1773 to the `notify' client operation. Affected files are
1774 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1776 * Added function silc_client_add_server to the client library.
1777 Added support for resolving also channel and server info when
1778 received unknown entity in notify packet. Affected files are
1779 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1781 * Added function silc_command_get_status to return the command
1782 status from the command reply's argument payload. Affected files
1783 are lib/silccore/silccommand.[ch].
1785 * Added check for KICKED notify type that the kicking is
1786 allowed by the client. Affected file silcd/packet_receive.c.
1788 * Created function silc_get_input which can be used to get input
1789 (echo on or off) from user on command line. Affected files are
1790 lib/silcutil/silcutil.[ch].
1792 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1794 * Optimized silc_server_packet_relay_to_channel function.
1795 Added new function silc_channel_message_payload_encrypt which
1796 can be called directly if channel message payload needs to
1797 be encrypted and is already encoded (no need to call _encode
1798 function). Packet relaying is now done by router without any
1799 extra memory allocations. Affected files are
1800 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1801 silcd/packet_send.c.
1803 * Fixed the INVITE notify handling. It took wrong arguments
1804 as invite list and invite delete. Affected file is
1805 silcd/packet_receive.c.
1807 * Added check for TOPIC_SET notify type that the topic change is
1808 allowed by the client. Affected file silcd/packet_receive.c.
1810 * Added check for INVITE notify type that inviting is allowed by
1811 the client. Affected file silcd/packet_receive.c.
1813 * Changed the silc_server_client_on_channel to return the
1814 SilcChannelClientEntry as well. Moved the function
1815 silc_server_check_cmode_rights to server_util.[ch].
1816 Affected files are silcd/server_util.[ch], silcd/command.c.
1818 * Added function silc_server_check_umode_rights to check whether
1819 changing client's user mode is allowed. Added check for
1820 UMODE_CHANGE notify type that the umode change is allowed
1821 by the client. Affected files are silcd/server_util.[ch],
1822 silcd/packet_receive.c and silcd/command.c.
1824 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1827 ID length. It ignored that ID can be IPv6 based as well.
1828 Affected file lib/silccore/silcpacket.h.
1830 * Fixed the silc_id_id2str and silc_id_str2id to take the
1831 IPv6 address offset's into consideration. Affecte file is
1832 lib/silccore/silcid.c.
1834 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1836 * Fixed the internal Unix scheduler functions to check for
1837 NULL context they may receive. The affected file is
1838 lib/silcutil/unix/silcunixschedule.c.
1840 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1842 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1843 can specify different directory with --home command line
1844 parameter. Affected files irssi/src/silc/core/client_ops.c,
1847 * SILC-specific commands aren't now executed if the active server
1848 isn't of SILC-type, so there won't be problems with having
1849 IRC and SILC protocol support in same client. Affected files
1850 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1853 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1855 * Improved the signal support in SILC Schedule. Added new
1856 function silc_schedule_signal_call which is used by application
1857 to mark a signal to be called. It is now safe to perform
1858 any kind of tasks in signal callbacks since it is guaranteed
1859 that the application specified signal callback is called
1860 after the signal is over. Affected files are
1861 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1863 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1865 * Added `name' field to SilcChannelPrivateKey to represent
1866 application given name for the key. Moved also the context from
1867 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1868 Added the `name' argument also to the function
1869 silc_client_add_channel_private_key.
1871 Added function silc_client_current_channel_private_key to set the
1872 current channel private key in use.
1874 Added "change" command to KEY command which can be used to change
1875 the current channel private key. Bound the command also to
1876 alt+K (Alt+Shift+k).
1878 Also affected files lib/silcclient/client_channel.c,
1879 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1881 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1883 * Added silc_rng_get_byte_fast function in to the
1884 lib/silccrypt/silcrng.[ch].
1886 * Changed the interface of silc_packet_assemble and the
1887 silc_packet_send_prepare. If silc_packet_assmble is now
1888 called the application does not call silc_packet_send_prepare
1889 because the library will call it automatically. These
1890 interfaces now also return a reference to the outgoing buffer
1891 which includes the assembled packet, which the application can
1892 use to encrypt the packet.
1894 Affected files are lib/silccore/silcpacket.[ch],
1895 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1896 silcd/packet_send.c, server_backup.c and packet_receive.c.
1898 * Fixed a packet sending bug on very high load, where outgoing
1899 packet queue wasn't handled correctly and packets got corrupted.
1900 Affected files are lib/silcutil/*/silc*sockconn.c,
1901 lib/silcclient/client.c and silcd/server.c.
1903 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1905 * Added macro SILC_PACKET_DATALEN which can be used during
1906 packet assembling to check whether the data to be added to
1907 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1908 len is truncated until it fits it.
1910 Added checks for maximum length of channel message payload and
1911 private message payload also.
1913 Added checks for maximum packet length in server and in
1916 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1917 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1918 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1919 lib/silcclient/client_prvmsg.c.
1921 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1923 * Added silc_server_packet_queue_purge call to the
1924 silc_server_disconnect_remote to assure that all data in the
1925 queue before disconnecting is sent to the network. Affected
1926 file silcd/server.c.
1928 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1930 * Added the deleting of server's own ID cache entry to the
1931 silc_server_free function. Free also everything else that
1932 has been allocated in silc_server_init. The affected file
1935 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1937 * Added functions silc_parse_version_string, silc_version_to_num,
1938 and silc_ske_parse_version to parse SILC protocol style version
1939 strings. Affected files lib/silcutil/silcutil.[ch] and
1940 lib/silcske/silcske.[ch].
1942 * Added new configuration params: version_protocol, version_software
1943 and version_software_vendor to specify what version the remote
1944 host must at least be to be able to connect to server. The vendor
1945 string can be regex matched too. Added new function
1946 silc_server_connection_allowed to check maximum number of allowed
1947 connections, and allowed versions for incoming connections.
1948 Affected files are silcd/server.c, server_util.[ch] and
1951 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1953 * Added preliminary support for signals in scheduler. The
1954 signals we care about are now blocked always when the scheduler
1955 is locked. This way we can synchronise the use of signal with
1956 scheduler. It is guaranteed that when signal occurs the scheduler
1957 is not locked, and thus new tasks can be safely added to the
1960 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1961 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1962 Added new platform specific routines
1963 silc_schedule_internal_signals_[un]block and
1964 silc_schedule_internal_signal_[un]register.
1966 Added new functions to SILC Schedule API:
1967 silc_schedule_signal_[un]register. Each signal that application
1968 is going to use should be registered to the scheduler.
1970 Affected files are lib/silcutil/silcschedule.[ch],
1971 lib/silcutil/*/silc*schedule.c.
1973 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1975 * Check for unauthenticated client and server in the
1976 silc_server_new_client and silc_server_new_server functions.
1977 Affected file silcd/packet_receive.c.
1979 * Added function silc_string_is_ascii to check whether given
1980 string is 7-bit ASCII string. Affected files are
1981 lib/silcutil/silcutil.[ch].
1983 * Added function silc_id_is_valid_server_id into the
1984 silcd/serverid.c and added checking for valid Server ID's in
1985 silc_server_new_server. The Server ID must always be based
1986 on the server's public IP address.
1988 * Added logging of DISCONNECT packet message in the server.
1989 Affected file silcd/server.c.
1991 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1993 * Changed all library interfaces that use Global RNG to also
1994 accept SilcRng as argument. Affected files are
1995 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1996 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1997 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1998 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1999 lib/silccrypt/rsa.c.
2001 * Added function silc_pkcs_generate_key to the
2002 lib/silccrypt/silcpkcs.[ch] for applications so that they
2003 don't need to do pkcs->pkcs->init calls anymore.
2005 * Remove SilcSocketConnection from the SFTP API since it really
2006 wasn't needed there. The application has the information
2007 saved in its contexts anyway and the SFTP layer doesn't need
2008 know about it. Affected files lib/silcsft/silcsftp.h and
2009 lib/silcsftp/sftp_[server/client].c.
2011 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2012 The SilcSimContext is not SilcSim.
2014 * Fixed possible buffer overflows in silc_id_render in the
2015 lib/silcutil/silcutil.c.
2017 * On EPOC the global crypto module lists are not used at all
2018 in the crypto library. Added support for using the constant
2019 algorithm list on EPOC. Affected files are
2020 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2023 * Fixed the handling of third parameter of KICKED notify, since
2024 it was mistakenly updated to SILC Protocol 1.0 even though it
2025 is to be included in 1.1. Since it is not in 1.0 it is not
2026 mandatory, and this fix now handles it only if it is provided,
2027 and it is not error if it is not provided. Affected file
2028 lib/silcclient/client_notify.c.
2030 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2032 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2033 client. Affected file irssi/src/silc/core/client_ops.c.
2035 * Merged with Irssi 0.8.4 from irssi.org CVS.
2037 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2039 * Check for valid socket connection in client entries before
2040 sending any messages. Fixes a crash, but doesn't fix some
2041 other underlaying bug that is lurking there. Affected
2042 file silcd/packet_send.c.
2044 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2046 * $usermode, $cumode and $cumode_space expandos shouldn't do
2047 anything with non-SILC server records. Affected file
2048 irssi/src/silc/core/silc-expandos.c
2050 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2052 * Fixed the silc_net_check_[host/local]_by_sock to support
2053 IPv6 bound sockets as well. Now they can return IPv6 addresses
2054 as well. Affected file lib/silcutil/silcnet.c.
2056 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2057 Affected lib/silcutil/unix/silcunixnet.c.
2059 * Fixed ID rendering (at least on some platforms, not NetBSD)
2060 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2062 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2064 * Added silc_hash_public_key and silc_hash_public_key_compare
2065 functions to be used with SilcHashTable. They can be used to
2066 hash public keys and compare public keys in hash table. Affected
2067 file lib/silcutil/silcutil.[ch].
2069 * Added support for specifying multiple public keys for Client
2070 connection section in server configuration file. This makes it
2071 possible to accept multiple public keys from same host, or to
2072 make a section that accepts any incoming host, and have the
2073 accepted public keys listed in the section.
2075 Added functions silc_sever_[find/get]_public_key, added the

2252 the SKE interface a bit.
2254 * Fixed padding problem in PKCS#1. The padding was not actually
2255 random since the random number generator was used incorrectly.
2256 This security bug affects only when encrypting with PKCS#1, and
2257 it is not currently used at all in SILC. SILC only use signing
2258 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2321 Affected files irssi/src/silc/core/silc-core.c,
2322 irssi/src/fe-text/silc.c.
2324 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2326 * Added new configuration options and blocks:
2327 keepalive_secs, reconnect_count, reconnect_interval,
2328 reconnect_interval_max, reconnect_keep_trying and
2329 require_reverser_lookup. Added ConnectionParam block, and
2330 implemented the connection parameters when connecting as
2331 initiator and when accepting connections as responder.

2343 the connection configuration object from the SilcServerConnection
2344 object instead of finding it during the connecting phase.
2345 Added the configuration object to SilcServerConnection struct.
2346 Affected files silcd/server_internal.h, server.c.
2348 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2350 * Add the client on channel after it was resolved at the
2351 channel message receiving, and it was not already on the
2352 channel. Affected file lib/silcclient/client_channel.c.
2354 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2370 authentication to be set at the same time.
2372 Added `prefer_passphrase_auth' setting in config file which
2373 can be used to set to prefer passwd auth if both passwd and
2374 public key is set. If not set, public key is preferred.
2375 This has effect only when being initiator (responder will try
2378 Added support for authentication with passphrase and public key
2379 at the same time. The passphrase is tried first always since
2380 it is faster to check.
2382 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2384 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2430 * Fixed the file transfer's key agreement payload to include
2431 zero port also if the hostname is NULL because it could not
2434 Call file transfer monitor callback now also if error occurs
2435 during key agreement protocol.
2437 Changed the silc_client_file_send interface to return the
2438 SilcClientFileError instead of session id. The session ID
2439 is returned into pointer provided as argument.

2454 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2455 SILC_LOG_WARNING to give out Warning and not Error. Affected
2456 file lib/silcutil/silclog.c.
2458 * Fixed the channel message payload decryption in the function
2459 silc_channel_message_payload_decrypt to not modify the original
2460 buffer before it is verified that the message decrypted
2461 correctly. Otherwise, next time it is called with correct
2462 channel key it won't encrypt since the payload is corrupted.
2463 Affected file lib/silccore/silcchannel.c.
2465 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2478 the table with foreach callback. The current entry may
2479 become invalid in the callback but it was referenced after
2480 the callback returned.
2482 Do not allow auto rehashing of hash table during the
2483 silc_hash_table_foreach operation, for same reasons as it is
2484 not allowed for SilcHashTableList. Affected files are
2485 lib/silcutil/silchashtable.[ch].
2487 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2511 * Fixed a bug in hash table tarversing. While the hash table
2512 is traversed with SilcHashTableList the table must not be
2513 rehashed. It is now guaranteed that auto rehashable tables
2514 are not rehashed while tarversing the list. Also defined that
2515 silc_hash_table_rehash must not be called while tarversing
2516 the table. Added function silc_hash_table_list_reset that must
2517 be called after the tarversing is over. The affected files are
2518 lib/silcutil/silchashtable.[ch].
2520 * Changed all hash table traversing to call the new
2521 silc_hash_table_list_reset in server and in client library.
2523 * Added function silc_client_on_channel to return the
2524 SilcChannelUser entry if the specified client entry is joined
2525 on the specified channel. This is exported to application as
2526 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2534 * Fixed the WHOWAS command's reply sending to support the
2535 lists correctly. Affected file silcd/command.c.
2537 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2539 * When sending JOIN command to router for processing the
2540 sender's old command identifier was not saved back to the
2541 sender's command context, fixed now. The affected file is
2544 * Create the key in JOIN command of the router did not return
2545 the channel key, added check for this. Affected file is
2548 * Fixed a channel ID update bug in JOIN command reply. Do
2549 not directly upgrade the ID but call the function
2550 silc_idlist_replace_channel_id if the ID was changed.
2551 Affected file silcd/command_reply.c.
2553 * Fixed memory leaks from command calling if it would fail.
2554 Affected file silcd/command.c.

2585 user list for the channel again, and server won't be in
2586 desync in some rare circumstances. Affected file is
2587 silcd/packet_receive.c.
2589 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2605 the SilcClientOperation functions in their application.
2606 Updated the lib/silcclient/README as well to tell about this
2607 nice file made available.
2609 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2611 * Call silc_server_remove_from_channels when removing client
2612 entry when NO_SUCH_CLIENT_ID was received. Affected file
2613 is silcd/command_reply.c.
2615 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2617 * Added server & router operator statistics updating. Affected
2618 file silcd/packet_receive.c and silcd/command.c.
2620 * Fixed the SERVER_SIGNOFF notify handling on normal server
2621 not to save the history information for clients. Same was
2622 fixed earlier in remove_clients_by_server function, but not
2623 here. Affected file silcd/packet_receive.c.
2625 * Raised the default connection-retry count from 4 to 7 in
2626 server. Affected file silcd/server.h.
2628 * Cancel any possible reconnect timeouts when we start the
2629 key exchange. Affected file silcd/server.c.
2631 * Do not reconnect on connection failure when SCONNECT was
2632 given. Affected files silcd/server.[ch].
2634 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2636 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2638 * Fixed the NICK command to always give the unformatted
2639 nickname to the one giving the NICK command. If unformatted
2640 nickname is cached already it will be formatted and the
2641 local entry will always get the unformatted nickname.
2642 Affected file lib/silcclient/idlist.c.
2644 * Fixed some double frees from client library commands.
2645 Affected file is lib/silcclient/command.c.
2647 * Fixed CUMODE command in server to assure that no one can
2648 change founder's mode than the founder itself, there was a
2649 little bug. Affected file silcd/command.c.
2651 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2653 * Removed the SilcClientCommandDestructor from the client
2654 libary, it is not needed anymore. Affected files are
2655 lib/silcclient/silcapi.h, command[_reply].[ch],
2656 client_notify, idlist.c.
2658 * Fixed GETKEY command to first resolve client, and then
2659 resolve the server only if the client was not found, instead
2660 of resolving both at the same time. Affected file is
2661 lib/silcclient/command.c.
2663 * Added silc_client_start_key_exchange_cb and lookup the
2664 remote hostname and IP address before starting the key
2665 exchange with server. The affected file is
2666 lib/silcclient/client.c.
2668 * The server's public key is now saved using the IP address
2669 of the server and not the servername for the filename.
2670 The hostname public key filename is checked as an fall back
2671 method if the IP address based filename is not found.
2673 Fixed the GETKEY command to save the fetched server key
2674 in correct filename.
2676 Print the remote server's hostname now when new key is
2677 received during connection process. Affected file is
2678 irssi/src/silc/core/client_ops.c.
2680 * Return always our own public key to the client if it asks
2681 for it with GETKEY command. Affected file silcd/command.c.
2683 * Removed the use_auto_addr variable from default config
2684 file since it was in wrong section. Affected file is
2687 * Fixed TOPIC_CHANGE notification to not route it when it
2688 was sent using silc_server_send_notify_to_channel function.
2689 Affected file silcd/command.c.
2691 * Fixed silc_server_send_notify_kicked to send the kicker's
2692 Client ID also, it was missing. Affected files are
2693 silcd/command.c, silcd/packet_send.[ch].
2695 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2697 * Do not save client history information in SERVER_SIGNOFF.
2698 Fixes the bug in normal server that it does not detect
2699 the client becoming valid after the server becomes back
2700 online. Affected file silcd/server_util.c.
2702 * Added `sock_error' field into the SilcSocketConnection
2703 context. When error occurs during socket operation (read
2704 or write) the error is saved. Added also new function
2705 silc_socket_get_error to return human readable socket error
2706 message. Affected files are lib/silcutil/silcsockconn.[ch],
2707 lib/silcutil/unix/silcunixsockconn.c, and
2708 lib/silcutil/win32/silcwin32sockconn.c.
2710 * The server now prints the socket error message in the
2711 signoff for client. Affected file silcd/server.c.
2713 * Fixed the `created' channel information sending from router
2714 to server in JOIN command. Checks now whether the channel
2715 really was created or not and set it according that.
2717 Fixed the JOIN command to use the client entry's current
2718 ID during the joining procedure instead of the one it sent
2719 in the command (it is checked though), since it can change
2720 between the packet processing and command processing, and
2721 would just case unnecessary pain in the client end. Affected
2722 file silcd/command.c.
2724 * Fixed a channel key payload sending to use correct channel
2725 ID when the server was forced to change the channel's ID by
2726 router. Router sent the key payload with the old Channel ID.
2727 Affected file silcd/packet_receive.c.
2729 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2731 * Call silc_server_save_channel_key only if the key payload
2732 was provided in the JOIN command's command reply. Affected
2733 file silcd/command_reply.c.
2735 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2737 * Fixed silc_mp_sizeinbase to return the value correctly with
2738 MPI. Affected file lib/silcmath/mp_mpi.c.
2740 * Fixed the stop_server signal to correctly stop the scheduler
2741 and gracefully stop the server when SIGTERM or SIGINT signals
2742 are received. Affected file silcd/silcd.c.
2744 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2746 * Simple handling of TERM and HUP signals. Also added some log
2747 flushing call around. Affected file is
2750 * Fixed small bugs in silclog.c. Now buffering output will take
2751 effect after 10 seconds since startup: This will ensure that
2752 no important startup messages are lost. Also output redirection
2753 will preserve original format ([Date] [Type] message).
2754 Affected file is lib/silcutil/silclog.c.
2756 * Added two options to the config file, in the logging section:
2757 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2758 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2760 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2762 * Do not print the warning about log files not being initialized
2763 more than once to avoid excess logging. Affected file is
2764 lib/silcutil/silclog.c.
2766 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2767 the SIM copying in make install in Makefile.am.pre.
2769 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2771 * Rewritten silclog APIs. Globally interesting changes follows:
2772 silc_log_set_files() changed to silc_log_set_file().
2773 silc_log_set_callbacks() changed to silc_log_set_callback().
2774 ROBOdoc documented silclog header file.
2775 SilcLogCb now returns bool to wether inihibit the default
2776 handler or not (to keep the old behaviour return always TRUE).
2777 The new APIs should also fix the problem of the
2778 silcd_error.log file that was written in the current directory.
2781 Log files streams will remain opened after silc_log_set_file()
2782 call, means less CPU usage notably on high traffic servers.
2783 File streams are now full buffered, and flushed to the disk
2784 every 5 minutes, lesses HD activity and CPU usage.
2785 Messages can be redirected, allowing admins to configure
2786 one single logfile for all server messages.
2787 the silc_log_quick global variable to activate fast-logging.
2788 Affected files lib/silcutil/silclog.[ch]
2790 * Changed some code to conform new silclog APIs. Affected
2791 files are doc/example_silcd.conf.in, silcd/server.c
2792 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2795 * Fixed a memory leak that could occur in some situations.
2796 Affected file silcd/serverconfig.c.
2798 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2800 * Added the silc_client_del_client to remove the client from
2801 all channels as well. Affected file lib/silcclient/idlist.c.
2803 * Fixed the client library to correctly remove the client
2804 from all channels when the client entry is being destroyed.
2805 Affected file lib/silcclient/client_notify.c, command.c.
2807 * Added auto-nicking support to the client library. If the
2808 applicatio now sets client->nickname it will be sent to the
2809 server after connecting by the library. This way for example
2810 SILCNICK (or IRCNICK) environment variables will have effect
2811 and always change the nickname automatically to whatever
2812 it is wanted. Affected file lib/silcclient/client.[ch].
2814 * Renamed silc_server_command_bad_chars to the
2815 silc_server_name_bad_chars and moved it to the
2816 silcd/server_util.[ch]. Added also new function
2817 silc_server_name_modify_bad to return nickname that
2818 includes bad characters as new nickname without those
2819 bad characters. This check and modify is now used in
2820 silc_server_new_client when the username is initially set
2821 as nickname, so it must be checked to be valid nickname.
2822 Affected file silcd/packet_receive.c.
2824 * The nickname length is now taken from the packet for real
2825 and not trusted to strlen() since it clearly can return
2826 wrong length for nickname including bad characters. This
2827 also applies to channel names. Affected file silcd/command.c.
2829 * Removed the lib/silcsilm/modules directory. Modules are now
2830 compiled into the lib/silcsim. Fixed the copying of the
2831 modules to follow symbolic links in Makefile.am.pre.
2833 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2835 * Fixed silc_string_regexify list creation. Fixes bugs with
2836 BAN and INVITE commands in server. The affected file is
2837 lib/silcutil/unix/silcunixutil.c.
2839 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Removed the command destructor entirely from the server's
2842 command and command reply routines. It is not needed, and
2843 its usage was buggy and caused crashes. Affected files are
2844 silcd/command[_reply].[ch].
2846 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Cancel protocol and NULL sock->protocol if timeout
2849 occurred during protocol. Affected file silcd/server.c.
2851 * Cancel protocol timeouts always before calling the final
2852 callback, to assure that after final callback is called
2853 no other state will be called for the protocol anymore.
2854 Affected file silcd/protocol.c.
2856 * Print error log if incoming connection configuration could
2857 not be found. Affected file silcd/server.c.
2859 * Fixed JOIN command to correctly save the founder mode
2860 to the client on normal SILC server, when the channel
2861 was created by the router. Affected file silcd/command.c.
2863 * Fixed LIST command (hopefully) to send correct reply
2864 packets. Affected file silcd/command.c.
2866 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * The silc_packet_receive_process now returns FALSE if the
2869 read data was invalid packet, and TRUE if it was ok.
2871 The server now checks that if unauthenticated connection
2872 sends data and its processing fails the server will close
2873 the connection since it could be a malicious flooder.
2875 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2877 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Make sure the warning about error opening a log file is
2880 printed only once and not everytime it fails (produces
2881 too much useless log). Affected file lib/silcutil/silclog.c.
2883 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2885 * Made the silc_server_daemonise() function more readable.
2886 Affected file silcd/server.c.
2888 * Pid file is now optional, the user may comment it out from
2889 the config file. Removed define SILC_SERVER_PID_FILE, we
2890 don't need a default any longer. Affected file
2891 configure.in.pre, lib/Makefile.am.pre.
2893 * Make some use of the pid file. The server now dies at startup
2894 if it detects a valid pid file on his path. The server would
2895 die anyway in this circumstance, because of the bind() failure.
2896 Affected file silcd/silcd.c.
2898 * No longer compiling lib/dotconf.
2900 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Fixed JOIN command parsing not to crash. Affected file
2903 lib/silcclient/command.c.
2905 * Fied the NICK_CHANGE notify to add the new client entry
2906 even it is resolved. This removes an <[unknown]> nick
2907 thingy bug in the client. Affected file is
2908 lib/silcclient/client_notify.c.
2910 * Do not try to allocate 0 bytes (efence does not like it)
2911 in lib/silccore/silccomand.c when encoding payload.
2913 * Do not take IRCNICK as nickname in Irssi SILC client since
2914 it is not possible to set nickname before hand connecting
2915 the server (TODO has an entry about adding auto-nicking
2918 * Changed the silc_server_command_pending to check whether
2919 there already exists an pending entry with the specified
2920 command, command identifier and pending callback. This is
2921 to fix IDENTIFY and WHOIS related crashes that may register
2922 multiple pending commands with same identifier. Affected
2923 file silcd/command.c.
2925 * Fixed the server to reconnect to the router even if it
2926 was already reconnecting and EOF was received. This to
2927 fix a possibility that the server wouldn't ever try to
2928 auto-reconnect to the router. Affected file silcd/server.c.
2930 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2932 * Fixed the server's password authentication to use the
2933 length of the locally saved password, and not the one
2934 sent in the packet. Affected file silcd/protocol.c.
2936 * Fixed same password authentication problem in the
2937 Authentication Payload handling routines in
2938 lib/silccore/silcauth.c.
2940 * Yet another password authentication problem fixed with
2941 channel password handling in silcd/command.c.
2943 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * If first character of string in silc_parse_userfqdn is '@'
2946 then do not parse it. Affected file is
2947 lib/silcutil/silcutil.c.
2949 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Fixed minor bug in IDENTIFY command reply sending, which
2952 caused various weird problems during JOIN when it was
2953 resolving names for users. Affected file silcd/command.c.
2955 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Fixed the IDENTIFY command reply sending to chech better valid
2958 clients. It was possible to send incomplete list of replies.
2959 Affected file silcd/command.c.
2961 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Added silc_client_command[s]_[un]register functions now to
2964 dynamically register the commands in client library. Removed
2965 the static table of commands. This allows the client library
2966 to call commands without causing the application to know about
2967 what commands library has called.
2969 Removed the INFO command reply kludge to detect when the command
2970 was called by library. Now library use its own command reply
2971 function for INFO command.
2973 Added function silc_client_command_call to call a command.
2974 Application can use it to call command, not access the structure
2977 Now all commands that are sent by the client library (not
2978 explicitly sent by application) use own command reply functions.
2980 Affected files around lib/silcclient/ and in
2981 irssi/src/silc/core/.
2983 * Fixed the WHOIS command reply sending to chech better valid
2984 clients. It was possible to send incomplete list of replies.
2986 Fixed the WHOIS and IDENTIFY to send the request to router
2987 if normal server did not do it and did not find any results.
2989 Affected file silcd/command.c.
2991 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Moved the internal data from SilcClient context into its
2994 own file, not accesible to application. Affected files
2995 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2996 and other files in client library.
2998 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Added doc/examples installation target in Makefile.am.pre.
3003 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3006 commands the found client entry will be removed from the
3007 cache, after notifying application about the error. Affected
3008 file lib/silcclient/command_reply.c.
3010 * Changed the /MSG to check for exact nickname user gave, and
3011 not let `nick' match `nick@host' if it is only one found. Now,
3012 user must type the exact nickname (like nick@host2) even if
3013 there are no more than one same nicks found. This is to avoid
3014 a possibility of sending nickname to wrong nickname since
3015 `nick' could match `nick@host'. Affected file is
3016 irssi/src/core/silc-servers.c.
3018 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Do not print "you are now server operator" or similar when
3021 giving /away command. Affected files are
3022 irssi/src/silc/core/client_ops.c, silc-servers.h.
3024 * Made the silc_server_command_pending_error_check to send
3025 the same command reply payload it received back to the
3026 original sender of the command. This way all arguments
3027 that was received by the server will be received by the
3028 client too. Affected file silcd/command.c.
3030 * Added the silc_idcache_add to return the created cache entry
3031 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3033 * Add global clients to expire if they are not on any channel.
3034 This is because normal server will never know if they signoff
3035 if they are not on any channel. The cache expiry will take
3036 case of these entries. This is done by normal servers only.
3037 The affected files are silcd/command_reply.c,
3038 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3040 * If server receives invalid ID notification for WHOIS or
3041 IDENTIFY and the ID exists in the lists, it is removed.
3042 Affected file silcd/command_reply.c.
3044 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3045 in client then client entry that it matches is searched and
3046 the nickname is printed on the screen for user. Affected
3047 file irssi/src/silc/core/client_ops.c.
3049 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Use cache entry expire time in the LIST command reply to
3052 purge old entries from the cache after the LIST command
3053 reply has been received. This way we don't have non-existent
3054 entries in the cache for too long. Affected file is
3055 silcd/command_reply.c.
3057 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * If we are normal server, and we've not resolved client info
3060 in WHOIS or IDENTIFY from router, and it is global client,
3061 we'll check whether it is on some channel. If it is not
3062 then we cannot be sure about its validity and will resolve it
3063 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3064 file silcd/command.c.
3066 * Search channel by name (if possible) rather than by ID
3067 in IDENTIFY command's command reply. Affected file is
3068 silcd/command_reply.c.
3070 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3073 Updated specs and implemented it. Affected file silcd/command.c,
3074 silcd/packet_send.c and silcd/packet_receive.c.
3076 * Implemented the <founder auth> payload handling in the JOIN
3077 command. If provided all conditions for channel joining
3078 except requirement to provide correct passphrase can be
3079 overrided by the channel founder. Updated the protocol specs.
3080 Affected file silcd/command.c.
3082 Added support for founder auth in JOIN command in client
3083 library. Fixed the parsing of the JOIN command now to support
3084 all options as they should be. The affected file is
3085 lib/silcclient/command.c.
3087 * Optimized the WHOIS and IDENTIFY commands to send the request
3088 to router only if it includes nicknames or other names. If
3089 they include only IDs then check the local cache first before
3090 routing. Affected file is silcd/command.c.
3092 * Added channels topic announcements. Affected file is
3093 silcd/packet_receive.c and silcd/server.c.
3095 * Fixed the silc_server_send_notify_topic_set to really destine
3096 the packet to channel. Affected file silcd/packet_send.c.
3098 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3099 library. Affected file lib/silcclient/client_notify.c.
3101 * Added UMODE announcements. Affected file silcd/server.c.
3103 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * Memory leak fixes in:
3107 lib/silcutil/silcsockconn.c
3108 lib/silcske/silcske.c
3109 lib/silcske/groups.c
3111 lib/silccrypt/silcpkcs.c
3112 lib/silccore/silccommand.c
3113 lib/silccore/silcidcache.c
3118 * ROBOdoc documented the lib/silcske/groups.h file and a
3119 bit changed the interface for better.
3121 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3123 * Update the client entry context in the ID cache after
3124 nick change. Affected file lib/silcclient/command.c.
3125 Fixes the CUMODE command when regaining founder privileges,
3126 and a little WHOIS problem.
3128 * Fixed silc_net_gethostbyname to correctly call the
3129 inet_ntop. Affected file lib/silcutil/silcnet.c.
3131 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3133 * Added IPv6 support checking to the configure.in.pre, added
3134 also --enable-ipv6 option to override the check. Affected
3135 file configure.in.pre.
3137 * The silc_thread_create now calls the start function
3138 directly if threads support is not compiled in. Removes
3139 ugly #ifdef's from generic code. Affected files are
3140 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3142 * Added silc_net_gethostby[name/addr]_async to asynchronously
3143 resolve. Affected files are lib/silcutil/silcnet.[ch].

3154 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3155 routines. Added silc_net_is_ip[4/6]. Affected file is
3156 lib/silcutil/unix/silcunixnet.c. All routines that take
3157 address as argument now supports both IPv4 and IPv6 addresses.
3159 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3161 * Fixed LIST command reply sending in server. Affected file
3164 * Server now sends the kicker's client ID in the KICK notify
3165 to the kicked client. Affected file silcd/command.c.
3167 * The client library now parses the kickers client ID and
3168 UI displays it. Affected files lib/silcclient/client_notify.c
3169 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3171 * Made all payload parsing function prototypes consistent.
3172 They all take now const unsigned char * and uint32 pair as
3173 the payload data instead of SilcBuffer. Changes all around
3174 the source tree. Other unsigned char* -> const unsigned char*
3175 changes around the tree as well.
3177 * Optimized SFTP client and server packet sending not to
3178 allocate new buffer for each packet but to recycle the
3179 first allocated buffer. Affected files are
3180 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3182 * Optimized the SFTP client to use SilcList instead of
3183 SilcDList for requests, because it is faster. Affected file
3184 is lib/silcsftp/sftp_client.c.
3186 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3187 into lib/silccore/silcid.[ch].
3189 Renamed silcpayload.[ch] into silcargument.[ch].
3191 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3193 * If client entry is deleted with active key agreement
3194 session, abort the session.
3196 The silc_client_abort_key_agreement now calls the completion
3197 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3199 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3202 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Don't use __restrict in older GCC's. Affected file is
3205 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3207 * silc_net_localhost now attempts to reverse lookup the
3208 IP/hostname. Affected file lib/silcutil/silcnet.c.
3210 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3211 command. It can be used to gain founder privileges at
3212 the same time when joining the channel.
3214 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3215 kicker's client ID as well. Updated protocol specs.
3217 Defined that the server must send SILC_COMMAND_IDENTIFY
3218 command reply with error status to client who sent
3219 private message with invalid client ID.
3221 Updated the protocol specification.
3223 * Added silc_server_send_command_reply to send any
3224 command reply. Affected file silcd/packet_send.[ch].
3226 * Added silc_id_payload_encode_data to encode ID payload
3227 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3229 * The server now send IDENTIFY command reply with error
3230 status if client ID in private message is invalid. Affected
3231 file silcd/packet_receive.c.
3233 * Save the server key file with server's IP address in
3234 the filename instead of hostname. The affected file is
3235 irssi/src/silc/core/client_ops.c.
3237 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3242 * Added libtool support for compiling shared objects in
3243 lib/silcsim. Affected file configure.in.pre and
3244 lib/silcsim/Makefile.am. Original patch by cras.
3246 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Pid file configuration, and server's config file fixes
3249 patch by toma. Updated CREDITS file.
3251 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3253 * Fixed silc_client_channel_message to not try to decrypt
3254 the message twice if it resolved the destination client
3255 information. This could cause of dropping one channel
3256 message. Affected file lib/silcclient/client_channel.c.
3258 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3261 lib/silcclient/client.c. This function is used when the SILC
3262 Client is run under some other scheduler, or event loop or
3263 main loop. On GUI applications, for example this may be
3264 desired to used to run the client under the GUI application's
3265 main loop. Typically the GUI application would register an
3266 idle task that calls this function multiple times in a second
3267 to quickly process the SILC specific data.
3269 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3271 * Fixed silc_server_drop() for dropping the supplementary
3272 groups as well, this could cause a security hole on some
3275 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3280 * Write PID file after dropping privileges. Added -F option
3281 to run server on foreground. A patch by debolaz.
3282 Affected files silcd/server.c, silcd/silcd.c.
3284 * Fixed MOTD to return the MOTD file server name. Affected
3285 file silcd/command.c.
3287 * Added INFO command reply handling to the Irssi SILC Client.
3288 Affected file irssi/src/silc/core/client_ops.c.
3290 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Fixed the silc_idcache_list_* routines to really support
3293 the dynamic list. Fixes a crash. Affected file is
3294 lib/silccore/silcidcache.c.
3296 * Fixed the LIST command reply to really call LIST command's
3297 pending callbacks. Affected file silcd/command_reply.c.
3299 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Update conn->local_entry->nickname after giving NICK
3302 command. Affected file lib/silcclient/command.c.
3304 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3306 * Added the [pid] option to the silcd configuration file
3308 Affected files: serverconfig.[ch] and silcd.c
3310 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Save fingerprint in WHOIS command reply in server.
3313 Affected file silcd/command_reply.c.
3315 * Fixed NICK commands pending callback registration.
3316 Affected file lib/silcclient/command.c.
3318 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Use ++server->cmd_ident when sending commands in server,
3321 instead of random number. Affected file silcd/command.c.
3323 * Fixed GETKEY command reply to call actually GETKEY pending
3324 command callbacks. Affected file silcd/command_reply.c.
3326 * A bit stricter check for nicknames. Check for same nickname
3327 in NICK command also. Affected file silcd/command.c.
3329 * Do not call INFO command everytime client ID changes, only
3330 during first connecting. Affected file lib/silcclient/client.c.
3332 * Set the new nickname only after successful command reply for
3333 NICK command is returned by server. Affected file
3334 lib/silcclient/command.c.
3336 * Remove nicknames from nicklist during server_signoff notify.
3337 Should fix /NAMES bit more. The affected file is
3338 irssi/src/silc/core/silc-channels.c.
3340 * Added `fingerprint' field to the SilcIDListData in the
3341 silcd/idlist.h to hold the fingerprint of the client's
3344 Send the fingerprint of the client's public key in WHOIS
3347 Affected files silcd/command.c, and silcd/idlist.[ch].
3349 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3350 create fingerprint from given data.
3352 * Show the fingerprint of the client's public key in WHOIS.
3353 Affected files irssi/src/module-formats.[ch] and
3354 irssi/src/silc/core/client_ops.c.
3356 * Format the multiple same nicknames also during JOIN and
3357 NICK_CHANGE notifys. Affected file is
3358 lib/silcclient/client_notify.c.
3360 * Do not print error on screen for invalid private message
3361 payload since it can come if someone is sending private
3362 messages with wrong key. Affected file
3363 lib/silccore/silcprivate.c.
3365 * Fixed multiple concurrent /PING crash. Affected file
3366 lib/silcclient/command.c.
3368 * Changed the wrong ID encoding. All IP addresses must be
3369 in MSB first order in encoded format. They were encoded
3370 wrong and was in LSB format. Affected files are
3371 silcd/serverid.c, lib/silcutil/silcutil.c.
3373 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3375 * Call the `connect' client operation through the scheduler
3376 in case of error. Affected file lib/silcclient/client.c.
3378 * Call the `failure' client operation even if the error
3379 occurred locally during a protocol. Affected file is
3380 lib/silcclient/protocol.c.
3382 * Added support of sending LIST command to router from normal
3383 server. This way normal server can get list of all channels
3384 in the network too. Fixed the channel list sending in the
3385 server too. Affected files are silcd/command.c, and
3386 silcd/command_reply.[ch].
3388 * Added silc_server_update_channels_by_server and
3389 silc_server_remove_channels_by_server. They are used during
3390 disconnection of primary router and in backup router protocol.
3391 Affected file silcd/server_util.[ch], silcd/server.c and
3392 silcd/server_backup.c.
3394 * Fixed channel adding to global list in IDENTIFY command
3395 reply in server. Affected file silcd/command_reply.c.
3397 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * If the incoming packet type is REKEY or REKEY_DONE process
3400 that packet always synchronously. Fixes yet another MAC
3401 failed error on slow (dialup) connections. Affected file
3402 lib/silcclient/client.c and silcd/server.c.
3404 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3406 * Call check_version SKE callback for initiator too. Affected
3407 file lib/silcske/silcske.c.
3409 * Implemented fix for security hole found in the SKE that was
3410 fixed in the specification few days back; the initiator's
3411 public key is now added to the HASH value computation.
3412 Added backwards support for the old way of doing it too, for
3413 old clients and old servers. Affected file is
3414 lib/silcske/silcske.c.
3416 * Enabled mutual authentication by default in SKE. If initiator
3417 is not providing mutual authentication the responder will
3418 force it. This will provide the proof of posession of the
3419 private key for responder. The affected files are
3420 lib/silcclient/protocol.c and silcd/protocol.c.
3422 * Do not cache anymore the server's public key during SKE.
3423 We do mutual authentication so the proof of posession of
3424 private key is done, and if the server is authenticated in
3425 conn auth protocol with public key we must have the public
3426 key already. Affected file silcd/protocol.c.
3428 * Added new global debug variable: silc_debug_hexdump. If
3429 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3430 file lib/silcutil/silclog.[ch].
3432 * Fixed compilation warning due to char * -> const char *.
3433 Affected files lib/silcutil/silcnet.h, and
3434 lib/silccore/silcauth.[ch].
3436 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Fixed CMODE command when new channel key was created. If
3439 the creation failed the old key was removed. Next time giving
3440 same command would crash the server since the old key was
3441 freed already. Affected file silcd/command.c.
3443 * Fixed the silc_server_announce_get_channels to not crash
3444 on reconnect. Affected file silcd/server.c.
3446 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Added silc_log_set_debug_string function to set a regex
3449 string to match for debug output. Only the function names,
3450 or filenames matching the given debug string is actually
3451 printed. This way it is possible to filter out those debug
3452 strings that user is not interested in.
3454 Fixed a bug in silc_string_regexify.
3456 Affected files lib/silcutil/silclog.[ch], and
3457 lib/silcutil/unix/silcunixutil.c.
3459 * Changed the -d options in both server and Irssi SILC client
3460 to take the debug string as argument. Affected files
3461 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3463 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Added silc_hash_babbleprint to create a Bubble Babble
3466 Encoded fingerprint. The encoding is developed by Antti
3467 Huima (draft-huima-babble-01.txt), and it creates human
3468 readable strings out of binary data. Affected file
3469 lib/silccrypt/silchash.[ch].
3471 * Print the babble print now in addition of fingerprint as well
3472 in Irssi SILC client. Affected files are
3473 irssi/src/fe-common/silc/module-formats.[ch],
3474 irssi/src/fe-common/silc/core/client_ops.c.
3476 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Fixed a security problem found in SKE. The initiator's
3479 public key too is now added to the HASH hash value creation
3480 which is signed by the responder to create the SIGN value.
3481 This will prevent anyone in the middle to lie to the responder
3482 about the initiator's public key. If this is done now, the
3483 man in the middle will get caught. Updated the protocol
3486 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Better installation directory handling. Configure module
3489 paths and other paths automatically to example_silc* files
3490 in doc/. A patch by toma.
3492 * Fixed compiler warning from MPI library, and from SILC RNG.
3495 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3496 It can be configured with ./configure. A patch by toma.
3498 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Find correct make to use in prepare-clean. A patch by
3501 toma. Affected file prepare-clean.
3503 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3505 * Added irssi variables use_auto_addr, auto_bind_ip,
3506 auto_bind_port and auto_public_ip.
3508 * Changed the interface for silc_client_send_key_agreement
3509 in lib/silcclient/silcapi.h
3513 irssi/src/silc/core/silc-core.c
3515 lib/silcclient/silcapi.h
3516 irssi/src/silc/core/silc-channels.c
3517 lib/silcclient/client_keyagr.c
3520 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3522 * Added silc_pkcs_public_key_compare to compare two
3523 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3525 * Check that the client who set the founder mode on the
3526 channel is the same client that is giving the founder
3527 mode to itself. It is done by comparing the saved public
3528 key (it is saved even in the authentication is passphrase).
3529 Affected file silcd/command.c.
3531 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Do not process packet for disconnected socket connection.
3534 Affected file lib/silccore/silcpacket.c.
3536 * Process the DISCONNECT packet through scheduler in the
3537 client library. Affected file lib/silcclient/client.c.
3539 * Fixed the silc_client_packet_parse to not to increase
3540 the packet sequence number if the conn->sock and the
3541 current socket connection is not same. This can happen
3542 for example during key agreement when the conn includes
3543 multiple socket connections (listeners). Affected file
3544 lib/silcclient/client.c.
3546 * The sender of the file transfer request now provides also
3547 the pointer (listener) for the key exchange protocol. If
3548 the listener cannot be created then it sends empty key
3549 agreement and lets the receiver provide the listener.
3551 Added `local_ip' and `local_port' arguments to the
3552 silc_client_file_send. If they are provided they are used,
3553 if not then it will attempt to find local IP address, if
3554 not found or bind fails then the remote client will provide
3557 Affected files are lib/silcclient/client_ftp.c and
3558 lib/silcclient/silcapi.h.
3560 * Extended the FILE SEND command to support defining the
3561 local IP and port for key exchange listener. They are
3562 optional. Affected file irssi/src/silc/core/silc-servers.c.
3564 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * Defined to WHOIS command reply the sending of fingerprint
3567 of the client's public key (if the proof of posession of the
3568 corresponding private key is verified by the server).
3569 Updated to the protocol specification.
3571 * Added support of receiving the client's public key's
3572 fingerprint in command reply in client library. Affected
3573 file is lib/silcclient/command_reply.c, and
3574 lib/silcclient/idlist.[ch].
3576 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Do not send over 128 chars long nickname to the server
3579 in NICK command. Affected file lib/silcclient/command.c.
3581 * Do not send over 256 chars long channel names to the server
3582 in JOIN command. Affected file lib/silcclient/command.c.
3584 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Assure that silc_server_close_connection cannot be called
3587 twice for same socket context. Affected file is
3590 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Send error message to application if opening file for
3593 writing during file transfer fails. Affected file is
3594 lib/silcclient/client_ftp.c.
3596 Remove all file transfer sessions for a client that we're
3597 removing from ID cache.
3599 Affected file is lib/silcclient/client_ftp.c.
3601 * Fixed silc_net_addr2bin to return correct address. Affected
3602 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3604 * Fixed file transfer session removing on signoff notify.
3605 Affected file irssi/src/silc/core/silc-servers.c.
3607 * Added the SilcClientFileError to be returned in the monitor
3608 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3609 Affected file lib/silcclient/silcapi.h.
3611 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3613 * Fixed a crash in silc_client_ftp_free_sessions and
3614 silc_client_ftp_session_free_client. Affected file
3615 lib/silcclient/client_ftp.c.
3617 * Added `disabled' field in the SilcChannelEntry in the server
3618 to indicate if the server entry is disabled. Affected file
3619 silcd/idlist.h, silcd/command[_reply].c.
3621 * SILC server adds now /var/run/silcd.pid everytime it is
3622 started. Affected file silcd/silcd.c.
3624 * Added silc_server_packet_send_clients to send a packet to
3625 the provided table of client entries. Affected file
3626 silcd/packet_send.[ch].
3628 * Fixed a crash in client resolving in client_prvmsg.c in
3629 client library. Affected file lib/silcclient/client_prvmsg.c.
3631 * Do not actually remove the client directly from ID cache
3632 during SERVER_SIGNOFF, but invalidate it. This way we
3633 preserve the WHOWAS info for the client. Affected file
3634 silcd/server_util.c.
3636 * Fixed SERVER_SIGNOFF notify handling in the server. The
3637 server is now able to process incoming SERVER_SIGNOFF notify
3638 for a server that it doesn't even know about. It will remove
3639 the clients provided in the notify. Affected file
3640 silcd/packet_receive.c.
3642 * Check for partial packet in data queue after every packet that
3643 was found from the queue. Return and wait for more data if
3644 there is partial data in queue. Affected file is
3645 lib/silccore/silcpacket.c.
3647 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3649 * Added SilcClietFileError enum to indicate error in
3650 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3651 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3652 Affected files lib/silcclient/silcapi.h and
3653 lib/silcclient/client_ftp.c.
3655 * Check that newsize in silc_buffer_realloc is larger than
3656 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3658 * Added better monitor of file transfers. It now monitors
3659 key agreement protocol during the file transfer too. Added
3660 error reporting too. Affected files
3661 irssi/src/silc/core/silc-servers.c,
3662 irssi/src/fe-common/silc/module-formats.[ch].
3664 * Wrote a help file for FILE command.
3666 * Added silc_rng_global_get_byte_fast to get not-so-secure
3667 random data as fast as possible. Random data is read from
3668 /dev/urandom if available and from the SILC RNG if not
3669 available. It is used in padding generation. Affected file
3670 lib/silccrypt/silcrng.[ch].
3672 * All packets in client library are now processed synchronously.
3673 Optimized packet processing a lot. Affected file
3674 lib/silcclient/client.c.
3676 * All server connection packets are processing synchronously
3677 now in server, to optimize packet processing. Affected file
3680 * Include files are installed now only in Toolkit distribution
3681 if make install is given. Affected files: all Makefile.am's.
3683 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3685 * Assure that silc_client_notify_by_server_resolve does not
3686 resolve the client information multiple times. If it cannot
3687 be found by the first it cannot be found at all. Affected
3688 file lib/silcclient/client_notify.c.
3690 * Fixed WHOWAS command reply calling. Affected file
3691 lib/silcclient/command_reply.c.
3693 * Removed all references to silc_idlist_get_client from the
3694 Irssi SILC client since that call is internal call used by
3695 the library. The Irssi SILC client will use now client
3696 retrieval functions found in silcapi.h.
3698 * Fixed a bug in resolving nickname info before sending
3699 private message. It used freed memory. Affected file
3700 irssi/src/silc/core/silc-servers.c.
3702 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Assure my_channels statistics cannot go negative in server.
3705 Affected files silcd/server.c, silcd/server_util.c.
3707 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3721 * Added silc_net_localip to return local host's IP address.
3722 Affected file lib/silcutil/silcnet.[ch].
3724 * If key exchange or rekey protocol is active for a connection
3725 parse all packets syncronously since there might be packets
3726 in packet queue that we are not able to process without first
3727 processing packets before them. Affected file silcd/server,
3728 lib/silcclient/client.c.
3730 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3731 whether library should continue processing the packet.
3732 Affected file lib/silccore/silcpacket.h.
3734 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3763 lib/silcutil/silcutil.[ch].
3765 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Resolve the client info when received private message or
3768 channel message for a client which nickname we don't know.
3769 Affected files lib/silcclient/client_prvmsg.c and
3770 lib/silcclient/client_channel.c.
3772 * Do not crash in /KEY if client is not connected. Affected
3773 file irssi/src/silc/core/silc-channels.c.
3775 * Added SilcClientStatus field to the SilcClientEntry in the
3776 lib/silcclient/idlist.h.
3778 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3779 is incomplete and is being resolved, it won't be resolved
3782 Make sure also that USERS command reply does not resolve
3783 twice information. Affected file is
3784 lib/silcclient/command_reply.c.
3786 Make sure that silc_client_get_clients_by_list does not
3787 resolve twice same information.
3789 * Check for valid client->id in the silc_server_free_client_data.
3790 Affected file silcd/server.c.
3792 * Fixed /GETKEY nick@server not to crash if the server entry
3793 is not found. Affected file lib/silcclient/command.c.
3795 * Fixed the silc_server_check_cmode_rights to check the
3796 requested modes correctly. Affected file silcd/command.c.

3800 * Better checks for non-printable chars in nick added.
3801 Affected file silcd/command.c.
3803 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Call the silc_server_udpate_servers_by_server in the
3806 primary router that comes back online in the backup resuming
3807 protocol. Otherwise it routes packets wrong. Affected file
3808 silcd/server_util.[ch], silcd/server_backup.c.
3810 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3813 lib/silcutil/silcbuffmt.[ch].
3815 * Redefined the SILC packet header to include the padding
3816 length. Affected file lib/silccore/silcpacket.[ch].
3818 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3819 length for maximum padding up to 128 bytes). Affected
3820 file lib/silccore/silcpacket.h.
3822 * Removed all backwards support for old 0.5.x MAC thingies.
3823 The SILC packet header change makes it impossible to be
3824 backwards compatible.
3826 * Send the ENDING packet with timeout in the backup resuming
3827 protocol. This is to assure that all routers has connected
3828 to the primary router. Affected file silcd/server_backup.c.
3830 * Changed the RNG to take the first IV from random data. It
3831 used to take it from zero actually. Changed the RNG also
3832 to use /dev/urandom during session. /dev/random is used
3833 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3835 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Changed the SILC packet header to have the first two bytes
3838 (the packet length) encrypted. Affected files aroung the
3839 code tree, lib/silccore/silcpacket.[ch]. Removed the
3840 SilcPacketCheckDecrypt callback. It is not needed anymore
3841 since the silc_packet_receive_process will determine now
3842 whether the packet is normal or special.
3844 * Implemented the unidirectional MAC keys. Affected files
3845 lib/silcske/silcske.c, silcd/protocol.c and
3846 lib/silcclient/protocol.c.
3848 * Implemented the packet sequence number to the MAC computation.
3849 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3850 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3851 lib/silcclient/protocol.c.
3853 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3855 * Allow backup router to announce servers. All servers
3856 announced by backup router are added to the global list
3857 automatically. Update hte server's socket to our primary
3858 router also when backup router announces a server.
3859 Affected file silcd/packet_receive.c.
3861 * Do not update the client->router in the function
3862 silc_server_udpate_clients_by_server if the client is on
3863 global list. We might fail to find any specific server
3864 for locally connected clients and local cell clients. They
3865 should still use the `from' and not `to' as client->router.
3866 This fixes backup router resuming protocol. Affected file
3867 silcd/server_util.c.
3869 * Decrease channel statistics count only if the channel
3870 deletion worked. Affected files are silcd/server.c and
3871 silcd/server_util.c.
3873 * Added silc_server_update_servers_by_server to update origin
3874 of all server entries. Used during backup router protocol.
3875 Affected files silcd/server_util.[ch], silcd/server.c. and
3876 silcd/backup_router.c.
3878 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3879 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3880 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3881 lib/silccrypt/silchmac.c.
3883 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Assure that router cannot reroute the same channel message
3886 to the sender. Affected file silcd/packet_receive.c.
3888 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3890 * Made better checks that the channel message is not sent
3891 to the router it came from. Affected file is
3892 silcd/packet_send.c. Fixed memory leak too.
3894 * Announce informations for incoming router connection, but
3895 only after checking if it is replaced by backup router.
3896 Affected file silcd/packet_receive.c.
3898 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Fixed the backup resuming protocol to work in multiple
3901 router environment. Affected file silcd/server_backup.c.
3903 * Route packet only to one router in the function
3904 silc_server_packet_send_to_channel. Affected file is
3905 silcd/packet_send.c.
3907 * Fixed silc_server_send_notify_dest to set the broadcast
3908 flag. Fixed the silc_server_send_notify_topic to actually
3909 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3910 Affected file silcd/packet_send.c.
3912 * Changed the SFTP Filesystem interface. Changed the
3913 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3914 the filesystem operation function. The SilcSFTPFilesystem
3915 is now a context that is allocated by all filesystem allocation
3916 functions and it already includes the operations structure
3917 and filesystem specific context. It is given as argument
3918 now to the silc_sftp_server_start. This made the interface
3919 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3920 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3922 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3924 * Changed the backup router adding and getting interfaces
3925 in the server. The router that will be replaced by the
3926 specified backup router is now sent as argument. Affected
3927 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3930 * Added silc_net_addr2bin_ne to return the binary form of
3931 the IP address in network byte order. Affected files
3932 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3934 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Check for existing server ID in silc_server_new_server
3937 and in silc_server_connect_to_router_final and remove the
3938 old entry if it exists. Affected file silcd/packet_receive.c,
3941 * Send the channel message always to only one router, either
3942 in upstream or downstream. Affected file is
3943 silcd/packet_send.c.
3945 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3947 * Wrote the definition of the backup resuming protocol to the
3948 protocol specification.
3950 * Removed one redundant channel key generation from normal
3951 server during joining procedure. Removed one redundant
3952 channel key sending from server to router during joining
3953 procedure. Affected file silcd/command.c.
3955 * Made minor bugfixes to the backup router resuming protocol.
3956 Affected file silcd/server_backup.c, server.c.

3960 * Added --disable-asm configuration option. Affected files
3961 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3964 * Implemented the backup resuming protocol that is used to
3965 resume the primary router position in the cell after the
3966 primary router comes back online. Affected files
3967 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3968 and silcd/server_util.[ch].
3970 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * Sleep two (2) seconds after sending QUIT command to server.
3973 Affected file lib/silcclient/command.c.
3975 * Assure that if outgoing data buffer is pending do not force
3976 send any data. Affected file silcd/packet_send.c.
3978 * Assure that if outgoing data buffer is pending do not force
3979 send any data. Affected file lib/silcclient/client.c.
3981 * Implemented the backup router support when the primary router
3982 goes down. The servers and routers can now use the backup
3983 router as new primary router without loosing connectivity.
3985 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3987 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3988 in the server to indicate disabled entry. All data read
3989 from the connection will be ignored and no data is sent
3990 for entry that is disabled. Affected files are
3991 silcd/idlist.h, silcd/server.c.
3993 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3995 * Created SFTP client and server test programs in the
3996 lib/silcsftp/tests directory.
3998 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Implemented memory filesystem (virtual filesystem) for
4001 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4004 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * Implemented the SFTP (SSH File Transfer Protocol) to the
4007 lib/silcsftp. It includes SFTP client and SFTP server
4010 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Moved lib/silccore/silcprotocol.[ch] to the
4013 lib/silcutil library.
4015 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4016 take variable argument list pointer as argument. Affected
4017 file lib/silcutil/silcbuffmt.[ch].
4019 * Added silc_buffer_set function that is used to set data
4020 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4021 Affected file lib/silcutil/silcbuffer.h.
4023 * Changed various routines in the core library to use the new
4024 silc_buffer_set instead of allocating new buffer only for
4027 * Added 64-bit value formatting and unformatting support to the
4028 silc_buffer_[un]format routines. Affected file is
4029 lib/silcutil/silcbuffmt.[ch].
4031 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4032 to includes/bitmove.h.
4034 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * Fixed channel user mode saving in client library. Affected
4037 file lib/silcclient/command[_reply].c.
4039 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Defined the file transfer to the SILC Protocol. Added
4042 new packet type SILC_PACKET_FTP and defined File Transfer
4043 Payload. The mandatory file transfer protocol is SFTP
4044 (SSH File Transfer Protocol). Affected file in addition
4045 of the internet draft is lib/silccore/silcpacket.h.
4047 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4048 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4049 is used as part of backup router protocol when the primary
4050 router of the cell is back online and wishes to resume
4051 the position as primary router.
4053 * Redefined the MAC generation keys in the protocol. The
4054 same key is not used anymore in both direction. Both
4055 direction will now use different keys for sending and
4056 receiving. This fixes a potential security flaw. This
4057 change causes incompatibilities in the protocol.
4059 * Redefined also the MAC computation from the packet.
4060 An packet sequence number is now added to the MAC
4061 computation. This prevents possible replay attacks against
4062 the protocol. This change too causes incompatibilities
4065 Added `sequence' field to the SilcPacketContext to hold
4066 the current sequence number for the packet.
4068 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Added `created' field to the SilcIDListData in the file
4071 silcd/idlist.h to indicate the time when the entry was
4074 * Added `created' field to the SilcChannelEntry too. Affected
4075 file silcd/idlist.h.
4077 * Added `creation_time' aguments to all the announcement functions
4078 in the server. If it is provided then only the entries that
4079 was created after the provided time frame are actually
4080 announced. Affected file silcd/server.[ch].
4082 * The protocol says that the Channel ID's IP address must be
4083 based on the router's IP address. Added check for this in
4084 the silc_server_new_channel when processing incoming New Channel
4085 Payload. Affected file silcd/packet_receive.c.
4087 * Print out the correct version with --version in SILC client.
4088 Affected file irssi/src/silc/core/silc-core.c.
4090 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4092 * Fixed WHOWAS command to check for completnes of the client
4093 entry always, not just when the command is coming from client.
4094 Affected file silcd/command.c.
4096 * Added new function silc_server_packet_queue_purge to purge the
4097 outgoing data queue to the network. After the function returns
4098 it is guaranteed that the outgoing packet queue is empty.
4099 Affected file silcd/packet_send.[ch].
4101 * Purge the outgoing packet queue in the rekey protocol's final
4102 callback to assure that all rekey packets go to the network
4103 before quitting the protocol. Affected file silcd/server.c.
4105 * Added silc_client_packet_queue_parse as similar function as
4106 in server to the client library. The affected file is
4107 lib/silcclient/client.c.
4109 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4111 * Splitted silcd/server.c and created silcd/server_util.[ch]
4112 for utility functions.
4114 * Added new socket flag SILC_SF_DISABLED to indicate that the
4115 connection is open but nothing can be sent to or received from
4116 the connection. Affected file lib/silcutil/silsockconn.[ch].
4117 The checking for disabled socket is checked in the low level
4118 silc_socket_write and silc_socket_read functions.
4120 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4122 * Allow only nicknames and channel names that fits into the
4123 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4125 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * When processing JOIN command reply in server check that if
4128 the channel exists in our global list we'll move it the local
4129 list. Affected file silcd/command_reply.c.
4131 * Fixed the check whether client is joined on the channel already
4132 in JOIN command. Affected file lib/silcclient/command.c.
4134 * Fixed the JOIN command reply to check whether the channel
4135 already exists. Affected file lib/silcclient/command_reply.c.
4137 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4139 * Added silc_ske_status_string to map the SKE error numbers
4140 to readable strings. The affected files are
4141 lib/silcske/silcske[_status].[ch].
4143 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4145 * Do not show the private channels on the WHOIS channel list
4146 as it is not allowed by the protocol. The affected file is
4149 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * Assure that the packet length digged from the actual packet
4152 is something sensible in the silc_packet_decrypt_rest_special
4153 in lib/silccrypt/silcpacket.c.
4155 * Free and NULL the allocated pointer in silc_hmac_alloc if
4156 the HMAC allocation fails. The affected file is
4157 lib/silccrypt/silchmac.c.
4159 * Print the selected security properties to the log files in
4160 the server. Affected file silcd/protocol.c.
4162 * Add SKE's reference counter even if calling the completion
4163 callback manually. Otherwise it goes negative, although it
4164 does not cause any problems. The affected file is
4165 lib/silcske/silcske.c.
4167 * Remove the client entry with short timeout after giving the
4168 KILL command. Affected file lib/silcclient/command.c.
4170 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4171 case all found clients are already disconnected (WHOWAS would
4172 found them) in the server. Affected file silcd/command.c.
4174 * Update the last_receive (time of last data received) to be
4175 updated only when received private or channel message so that
4176 the idle time showed in WHOIS makes more sense.
4178 * Added boolean field `valid' in to the SilcClientEntry in the
4179 client library to indicate whether the entry is valid or not.
4180 This fixes the nickname change bug on channel when changing
4181 the nickname to be same than the old (like nick to Nick) the
4182 nickname formatter doesn't set the new nick anymore to Nick@host.
4183 Affected file lib/silcclient/idlist.[ch].
4185 * Now actually fixed the nickname changing on disconnection.
4186 Added new function silc_change_nick to the Irssi SILC Client.
4187 Affected file irssi/src/silc/core/client_ops.c,
4188 irssi/src/silc/core/silc-nicklist.[ch].
4190 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4192 * Check that the public key exists in the GETKEY command before
4193 trying to encode it. Affected file silcd/command.c.
4195 * Print some notifications on received public keys with GETKEY
4196 command in the Irssi SILC Client. Affected files are
4197 irssi/src/fe-common/silc/module-formats.[ch],
4198 irssi/src/silc/core/client_ops.c.
4200 * Use IDENTIFY command to resolve the server information in the
4201 GETKEY command instead of INFO command. Affected file
4202 lib/silcclient/command.c.
4204 * All command reply functions in the client library now calls
4205 the pending command reply callbacks even if an error has
4206 occurred. The server has done this a long time and now it was
4207 time to move the client library to this as well. Now all
4208 errors can be delivered back to the pending command reply
4209 callbacks if necessary. Affected files are
4210 lib/silcclient/command[_reply].[ch].
4212 * Change the nickname on disconnection back to the username
4213 because in reconnect the server will enforce it to it anyway.
4214 Affected file irssi/src/silc/core/silc-servers.c.
4216 * Fixed a config file parsing bug in the Irssi SILC client.
4217 Affected file irssi/src/silc/core/clientconfig.c.
4219 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4221 * When printing the channel mode on JOIN, verify that the
4222 channel key and channel's HMAC are valid. Affected file
4223 irssi/src/silc/core/client_ops.c.
4225 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4227 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4228 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4229 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4231 * Removed channel key rekey task deleting from the function
4232 silc_server_save_channel_key. Affected file silcd/server.c.
4233 Added explicit timeout task context instead that is used to
4234 delete the task if we are registering a new task before the
4235 new task has elapsed.
4237 * When channel key rekey occurs the client library now saves
4238 the old channel key for a short period of time (10 seconds) and
4239 is able to use it in case some is still sending channel
4240 messages encrypted with the old key after the rekey. Affected
4241 file lib/silcclient/[idlist.h|client_channel.c].
4243 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4245 * Added check to the silc_server_new_id_real to not accept
4246 new ID if it is the sender's own ID. Affected file is
4247 silcd/packet_receive.c.
4249 * Assure that we do not announce ourself or the one we've
4250 sending our announcements when we're router and are announcing
4251 servers to our primary router. Affected file silcd/server.c.
4253 * Fixed silc_server_command_identify_check_client to assemble
4254 correct WHOIS packet. It send corrupted WHOIS packet and
4255 caused problem with router to router connections. Affected
4256 file silcd/command.c.
4258 Fixed also silc_server_command_whois_check the same way
4259 as for the IDENTIFY command.
4261 * Added new SilcIDListStatus to the server in the SilcIDListData
4262 structure. The status now includes the current status of
4263 the entry (like registered, resolved etc.). Affected file
4264 silcd/idlist.[ch]. Defined a bunch of different status types
4265 as well. This replaced the old boolean registered field as well.
4267 Added resolve_cmd_ident field to the SilcClientEntry structure
4268 too so that if the entry is for example being resolved so
4269 another command may attach to the same pending command reply
4270 without requiring to resolve the same entry again. This concept
4271 should optimize the WHOIS and the IDENTIFY resolving under
4272 heavy load by taking away unnecessary resolving for entries
4273 that are being resolved already.
4275 Added support for adding multiple pending commands for one
4276 command idenfier. Affected file silcd/command[_reply].[ch].
4278 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4279 before deleting the data. Otherwise the hash table will have
4280 freed data in comparison functions. Affected file is
4281 silcd/command_reply.c.
4283 * Fixed silc_idlist_replace_client_id to add the new entry to
4284 the cache with NULL nickname. Otherwise there will be invalid
4285 memory as the nickname after the nickname is freed. Affected
4286 file silcd/packet_receive.c.
4288 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4289 saved into wrong slots because the previous number of entries
4290 was not taken into account. Affected file silcd/idlist.c.
4291 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4293 * If we are router and we receive JOIN notify to a channel that
4294 does not have any users then notified client is marked as the
4295 channel founder, as it is it. The affected file is
4296 silcd/packet_receive.c
4298 * Added to the extended hash table API's table_del_*ext functions
4299 the destructor as argument too, so that the caller can decide
4300 which destructor to use or whether to use destructor at all.
4301 Affected file lib/silcutil/silchashtable.[ch].
4303 * Fixed ID Cache purging. It actually deleted the entries from
4304 the hash table after the data was freed. The hash table ended
4305 up comparing freed memory. The affected file is
4306 lib/silccore/silcidcache.c.
4308 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4310 * Fixed Irssi SILC client's KILL command's HELP syntax.
4312 * The USERS command now resolves the detailed user information
4313 if the userinfo field is missing. Affected file is
4314 lib/silcclient/command_reply.c.
4316 * Do not print error in silc_file_read if the read file does
4317 not exist. Just silently return NULL. Affected file is
4318 lib/silcutil/silcutil.c.
4320 * Fixed the silc_log_output to not wine about NULL filename
4321 and to not create some bogus " " filename. Affected file is
4322 lib/silcutil/silclog.c.
4324 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4326 * Fixed various printing bugs on the user interface in the
4327 Irssi SILC Client. Minor changes that were forgotten from
4330 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4332 * Fixed the configure.in.pre and the compilation and distribution
4333 environment to support the new autoconf 2.52. That version is
4334 now required to compile the CVS trunk.
4336 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4338 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4339 to generally parse user@fqdn format strings. Affected file
4340 lib/silcutil/silcutil.c.
4342 * Added nickname_format and nickname_force_format fields to the
4343 SilcClientParams structure. The first one defines the format
4344 for the nicknames that the library will enforce if the receives
4345 multiple same nicknames. The second one is boolean value and
4346 can be used to force the library to always enforce the format
4347 to the nicknames regardles whether there are multiple nicknames
4348 or not. This configurable formatting was employed to flexibly
4349 support accessing multiple nicknames from the user interface.
4350 The userinterface can now set the nicknames to what ever format
4351 they prefer. Affected file lib/silcclient/silcapi.h.
4353 Added function silc_client_nickname_format to the file
4354 lib/silcclient/idlist.c. It performs the nickname formatting.
4356 Added new field `hostname´ to the SilcClientEntry context.
4357 It holds the hostname of the client. Affected file is
4358 lib/silcclient/idlist.h.
4360 * Irssi SILC Client sets the nicknames in nick@hostn format.
4361 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4362 irssi/src/silc/core/silc-core.c.
4364 The WHOIS printing now also shows both the real nickname and
4365 the formatted nickname so that user knows how to access the
4366 user if there are multiple same nicknames cached. Affected
4367 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4368 printing formatting too to take the hostname now as a separate
4369 argument. The Affected file is
4370 irssi/src/fe-common/silc/modules-formats.[ch].
4372 * Changed the silc_client_get_clients_local to accept the formatted
4373 nickname as argument. It accepts the real nickname too but the
4374 formatted nickname can be used to find the true entry from
4375 multiple entries. Affected file lib/silcclient/silcapi.h and
4376 lib/silcclient/idlist.c.
4378 * Added nickname_format_parse field to the SilcClientParams.
4379 It is a callback function provided by the application to parse
4380 the nickname out of the formatted nickname string. The library
4381 calls it to get the nickname from the formatted string. Since
4382 the application generally knows better the format of the nickname
4383 string it parses it instead of the library, even though library
4384 encodes the formatted string. If the callback function is not
4385 provided then the library will use the string as is. The
4386 affected file is lib/silcclient/silcapi.h.
4388 * All the nickname strings passed to the client library in
4389 commands are now expected to be formatted nickname strings.
4390 If the command does not support the formatted nickname string
4391 it will assume that the sent string is the actual nickname.
4392 Affected file lib/silcclient/command.c.
4394 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4396 * Added public key authentication support to OPER and SILCOPER
4397 commands in the client library. Affected file is
4398 lib/silcclient/command.c.
4400 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4402 * Changed the get_auth_methdod client operation to be asynchronous.
4403 It can be async if the application resolves the authentication
4404 method from the server during the negotiation. Added new
4405 SilcGetAuthMeth completion callback that the application will
4406 call after resolving the authentication method.
4408 Added function silc_client_request_authentication_method that
4409 the application can use to resolve the authentication method
4410 from the server. Added also SilcConnectionAuthRequest callback
4411 that the library will call after the server has replied. The
4412 application can call this function if it does not know the
4413 current authentication method.
4415 Affected files are lib/silcclient/client.c and
4416 lib/silcclient/silcapi.h.
4418 * The Irssi SILC client now automatically resolves the authentication
4419 method incase any configuration information is not present (and
4420 currently there never is). The affected file is
4421 irssi/src/silc/core/client_ops.c.
4423 * Fixed public key authentication from the client library.
4424 Affected file lib/silcclient/protocol.c. Changed also the
4425 protocol specification about the public key authentication in
4426 the connection authentication protocol. The actual data to be
4427 signed is now computed with a hash function before signing.
4429 * Fixed the public key authentication from the server as well.
4430 Affected file silcd/protocol.c.
4432 * Removed the mlock()'s from the memory allocation routines.
4433 Affected file lib/silcutil/silcmemory.c. The ./configure does
4434 not check anymore for the mlock(). Affected file is
4437 * Fixed USERS command in server to allow the execution of the
4438 command for private and secret channels if the client sending
4439 the command is on the channel. Affected file silcd/command.c.
4441 * Fixed silc_client_get_clients_local to return the clients
4442 count correctly. It could return wrong value. Affected file
4443 lib/silcclient/idlist.c.
4445 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4447 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4448 types. The assembler optimizations seemed not to like 64-bit
4449 data types. The assmebler optimizations thus are now enabled
4450 also for BSD systems as opposed to only enable them for Linux.
4452 * Do not check for threads at all on BSD systems. Affected
4453 file configure.in.pre.
4455 * Removed -n and -h options from the Irssi SILC Client since
4456 they are not used in silc.
4458 * Fixed the prime generation to assure that the first digit
4459 of the generated random number is not zero since our conversion
4460 routines does not like number strings that starts with zero
4461 digit. If zero digit is seen the random number is regenerated.
4462 This caused some corrupted RSA keys when the zero first digit
4463 was met. Affected file lib/silcmath/silcprimegen.c.
4465 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Fixed WIN32 configuration in the ./configure script.
4468 Fixed to include xti.h on environments that has it.
4469 Patches by Carsten Ilchmann and andrew.
4471 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4473 * Changed the silc_id_create_client_id to be collision
4474 resistant. It is now assured that there cannot be created
4475 two same client ID's. I suspect that some weird bugs in
4476 the server were actually caused by duplicate Client IDs.
4477 Affected file silcd/serverid.[ch]. A router receiving
4478 new ID now also assures and informs the sending server
4479 if the ID caused collision.
4481 * Changed the silc_id_create_channel_id to also assure that
4482 there are no collisions.
4484 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4486 * Statement about ignoring the Mutual Authentication flag when
4487 performing rekey with PFS was a bit misleading. It is ignored
4488 if it was set in the initial negotiation, it cannot be even
4489 set in the rekey. Fixed in the ke-auth draft. Started the
4490 new versions of the protocol drafts in the doc/.
4492 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4494 * Fixed a bug in silc_client_command_identify_save when saving
4495 new channel information. The channel name was no duplicated
4496 and caused crash on exit. Affected file is
4497 lib/silcclient/command_reply.c.
4499 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4501 * Fixed the getkey command handling in the server. Send just
4502 empty OK reply to the sender if the key could not be fetched
4503 (but everything else was ok, like the key just was not available).
4504 Changed the public key parameter to optional in the protocol
4505 specs so that empty OK reply can be sent. Affected file
4508 Added a message to Irssi SILC client to tell to user if the
4509 server did not return a public key.
4511 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4513 * Fixed a channel key regeneration bug. It registered new
4514 timeout tasks exponentially until all system resources were
4515 used. Affected file silcd/server.c.
4517 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4519 * Added the SILC Document generator to the scripts/silcdoc.
4520 It can be used to generate the Toolkit Reference Manual out
4521 of the source tree. Internally it will also use the RoboDoc
4522 generator now imported in util/robodoc.
4524 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4526 * Added couple of return's in rekey protocol if error orccurred
4527 during the protocol. The execution must be terminated.
4528 Affected file silcd/protocol.c. Also, terminate the protocol
4529 always with timeout.
4531 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4533 * The client's Client ID was created initally from the wrong
4534 nickname (it could have been in format nick@host) in the
4535 silc_server_new_client. Affected file silcd/packet_receive.c
4537 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Added some SILC_LOG_ERROR's to various error conditions
4540 if client could not be added to ID cache. Affected files
4541 silcd/packet_receive.c and silcd/server.c.
4543 * When client's sock->user_data is freed, NULL also the
4544 client->router and client->connection pointers. Added check
4545 for these pointers being NULL to various places around the
4546 code. Affected file silcd/server.c.
4548 * Added client->data.registered == TRUE checks to various
4549 places around the code to assure that unregistered client's
4550 are not handled when it is not allowed. Affected file
4553 * Added `bool registered' fields to all
4554 silc_idlist_[server|client]_get_* routines to indicate whether
4555 the fetched client needs to be registered or not. Affected
4556 file silcd/idlist.[ch].
4558 * Add your own entry as registered to the ID cache in the
4559 server. Affected file server.c.
4561 * Fixed a bug in silc_server_new_server. The SilcServer was
4562 set as the new server's context instead of SilcServerEntry.
4563 This naturally caused some weird bugs.
4565 * Added "updated" field the SilcChannelEntry which indicates
4566 the time since the channel entry was last accessed. This
4567 can be used to determine whether it is necessary to
4568 announce the channel after backup resuming protocol.
4569 Affected files silcd/idlist.[ch].
4571 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4573 * Do not delete the channel rekey task when adding it
4574 for in silc_server_create_channel_key.
4576 * Changed the silc_server_create_channel_key to return
4577 TRUE or FALSE to indicate the success of the channel key
4580 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4582 * Fixed MSVC++ project files and added missing files to
4583 Makefiles under win32/.
4585 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4587 * Do not add TCP_NODELAY flag if the operating system
4588 does not have it defined. Affected files are
4589 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4591 * Fixed buffer overflow from Irssi SILC Client. Affected
4592 file irssi/src/fe-common/core/themes.c.
4594 * Fixed double free in client library in the file
4595 lib/silcclient/client.c when disconnecting from server.
4597 * Applied double free patch from cras to Irssi SILC client.
4598 Affected files irssi/src/core/[modules/expandos].c
4600 * Fixed the disconnection handling to Irssi SILC Client.
4601 The application must call silc_client_close_connection
4602 in ops->connect client operation in case of failure of
4603 the connection. Affected file is
4604 irssi/src/silc/core/client_ops.c.
4606 * Do not set sock->protocol to NULL in the function
4607 silc_client_close_connection after executing the protocol's
4608 final callback since the sock might not be valid anymore.
4609 Affected file lib/silcclient/client.c.
4611 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4613 * Do not enable SILC_THREADS if the linking with libpthread
4614 did not happen. Affected file configure.in.pre.
4616 * Added notion to protocol specification that server must
4617 verify the sent authentication payload with CMODE when
4618 setting the channel founder key. Implemented it to the
4619 server. Affected file silcd/command.c.
4621 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4623 * Added _EXTRA_DIST SILC distribution variable to the
4624 distributions file. It is used to conditionally add extra
4625 files or directories to the specific distribution. Affected
4626 files ./prepare, Makefile.am.pre and distributions.
4628 Removed the `_' from the start of the distribution names.
4631 * Added README.WIN32 for instructions to compile the Toolkit
4634 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Fixed a double free in disconnection in the server. Affected
4637 file is silcd/server.c.
4639 * Fixed the lib/silcske/groups.c to work now also with GMP
4640 MP library. The string conversion did not work when using
4641 specific base and the base is indicated in the string as well.
4643 * Created win32/ directory which now includes MSVC++ specific
4644 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4645 It will appear only in the toolkit distribution
4647 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Changed the key material distribution function in case when
4650 the hash output is too short. The data is now concatenated
4651 a bit differently than it used to. Made the change to the
4652 SKE protocol specification.
4654 * Added better GMP detection to configure.in.pre. A patch
4657 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4659 * Fixed a minor bug in SKE that might cause some problem on
4660 some platforms. Affected file lib/silcske/silcske.c.
4662 * Added the cookie checking for initiator in the SKE. It checks
4663 that the responder returns the sent cookie unmodified. The
4664 affected file is lib/silcske/silcske.c. Added new SKE
4665 error type INVALID_COOKIE that can be sent during the
4666 negotiation. Fixed some memory leaks as well.
4668 * Added the "invalid cookie" error message to Irssi SILC client's
4671 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Added `task_max' field to the SilcClientParams to indicate
4674 the maximum tasks the scheduler can handle. If set to zero,
4675 default values are used. Affected file lib/silcclient/silcapi.h.
4677 * Fixed memory leaks in silc_client_close_connection. Affected
4678 file lib/silcclient/client.c.
4680 * Added silc_client_del_client_entry to client library to free
4681 all memory of given client entry. Affected file is
4682 lib/silcclient/idlist.[ch].
4684 * Added new functions silc_client_del_channel and
4685 silc_client_del_server to delete channel and server entries.
4686 Affected file lib/silcclient/[silcapi.h/idlist.c].
4688 * Removed silc_client_del_client_by_id from silcapi.h.
4690 * Fixed the INFO command to return the server's own info
4691 correctly when querying by Server ID. Affected file is
4694 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4696 * Removed the non-blocking settings in WIN32 code in the
4697 silc_sock_[read/write] and added SleepEx instead. Affected
4698 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4699 of input data is now checked with FIONREAD and ioctlsocket.
4701 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4703 * Call silc_schedule_task_del_by_context in the
4704 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4705 Affected file lib/silccore/silcprotocol.c.
4707 * Call silc_protocol_cancel for active protocols in the
4708 silc_server_close_connection if the funtion
4709 silc_server_free_sock_user_data has not been called.
4710 Affected file silcd/server.c.
4712 * Generic tasks cannot be deleted using the del_by_fd
4713 task deleting function since generic tasks does not match
4714 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4716 * Added a notion to SILCOPER help file that the SILCOPER works
4717 only on router server, not on normal server.
4719 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4721 * Added for WIN32 support for the new scheduler as well.
4722 Affected file lib/silcutil/win32/silcwin32schedule.c.
4724 * Fixed the SHA1 implementation to work on various platforms.
4726 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4728 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4729 API. It is part of the scheduler now. Everything else is
4730 as previously but some functions has changed their names.
4731 Checkout the lib/silcutil/silcschedule.h for the interface.
4732 Updated all applications to use the new interface. Affected
4733 files are lib/silcutil/silcschedule.[ch].
4735 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4737 * Found a bug in the SKE implementation. The HASH value,
4738 specified by the protocol, was not computed correctly. The
4739 public key of the responder was not added to the computation
4740 even though it is mandatory. Affected file lib/silcske/silcske.c.
4741 This unfortunately causes incompatibilities with older
4742 clients and servers.
4744 * Added WIN32 specific network init and uninit functions:
4745 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4746 the Winsock2. Affected file lib/silcutil/silcnet.h and
4747 lib/silcutil/win32/silcwin32net.c.
4749 * Set the socket always to nonblocking mode on WIN32 after
4750 reading data or writing data. Affected file is
4751 lib/silcutil/win32/silcwin32sockconn.c.
4753 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4755 * Fixed various compilation problems under WIN32. Affected
4756 files lib/silcutil/win32/silcwin32thread.c and
4757 lib/silcutil/win32/silcwin32schedule.c.
4759 * Removed all _internal.h #includes from public header
4760 files. Internal headers must never be included from
4763 Removed also the lib/silcske/payload_internal.h file.
4765 * All include files that may be needed (public and some others
4766 included by the public headers) by application developers are
4767 now copied to the ./includes directory. It does not copy any
4768 internal headers. Affected file Makefile.defines.pre and all
4769 Makefile.am's under lib/ and subdirs.
4771 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4773 * Do not change the ~/.silc directory's permissions automatically.
4774 Affected file irssi/src/silc/core/clientutil.c.
4776 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4778 * Do not cancel the protocol in silc_server_close_connection
4779 it might cause recursion. Now cancelled in the function
4780 silc_server_free_sock_user_data. Affected file silcd/server.c.
4782 * Fixed the silc_server_remove_clients_by_server to regenerate
4783 the channel keys correctly finally. Added also new function
4784 silc_server_remove_clients_channels to actually do it.
4785 Affected file silcd/server.c.
4787 * Fixed the silc_server_new_channel to not crash by giving
4788 wrong router to the new channel. Affected file is
4789 silcd/packet_receive.c.
4791 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4793 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4794 which is given as argument to the silc_client_alloc now.
4795 It can be used to configure the client and set various parameters
4796 that affect the function of the client.
4798 * The USERS command in server did not check whether the channel
4799 is private or secret. Affected file silcd/command.c.
4801 * Added new argument to the USERS command in protocol specification.
4802 The USERS command now can take the channel name as argument
4803 as well. Added support for this in client and server and
4804 updated the protocol specs.
4806 * Completed the GETKEY command in client. It can be now used
4807 to fetch also servers public key not only some clients.
4808 Affected files lib/silcclient/command[_reply].c.
4810 * Added silc_client_get_server to return server entry by the
4811 server name. Affected files lib/silcclient/silcapi.h and
4814 * Redefined the IDENTIFY command in protocol specification to be
4815 more generic. It now can be used to query information about
4816 any entity in the SILC Network, including clients, servers and
4817 channels. The query may be based either the entity's name
4818 or the ID. Added support for this in both client and server.
4820 Affected files silcd/command.c and lib/silcclient/command.c
4821 and command_reply.c.
4823 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4824 the _from_client and _from_server functions. Affected file
4827 * Added silc_client_get_channel_by_id_resolve to the file
4828 lib/silcclient/silcapi.h to resolve channel information by
4829 its ID. Added also silc_client_get_channel_by_id that
4830 does not resolve it from the server.
4832 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4834 * Added SilcServerEntry context into the client library
4835 to represent one server. The INFO command now allocates
4836 these to save the resolved server info. For now on the
4837 client library will also keep information about servers,
4838 connected and resolved with INFO.
4840 The INFO command now allocates the SilcServerEntry context
4841 and saves the server info there. The COMMAND_REPLY in
4842 the INFO now returns the parameters to application in
4843 same order as defined in the protocol specification.
4845 The entries are cached in the client->server_cache.
4847 * The INFO command is now issued after received the Client ID
4848 from the server. Affected file lib/silcclient/client.c.
4850 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4851 to the application as the mode changer might be server.
4852 It is guaranteed that NULL is not returned anymore to the
4853 application. Affected file lib/silcclient/client_notify.c.
4855 The ID Type is now also passed to the application so that
4856 it can check whether the returned entry is SilcClientEntry
4859 Added new function silc_client_get_server_by_id to return
4860 the server entry by ID. Affected files are the
4861 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4863 * Do not create the channel in the Irssi SILC Client when issuing
4864 the JOIN command but when received the sucessful JOIN command
4865 reply. Otherwise the channel might get created even though we
4866 could not join it. The Affected file is
4867 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4869 * Fixed a channel joining bug in router. The router must also
4870 check the channel modes, invite and ban lists etc. when serving
4871 the JOIN command sent by normal server. Affected file is
4872 silcd/command.c. The router now resolves the client's
4873 information from the server who sent the JOIN command if it
4874 does not know it, and processes the JOIN command only after
4877 * Changed the SilcCommandCb to take new argument; void *context2.
4878 Affected file lib/silccore/silccommand.h
4880 The second argument in the command callbacks in the server now
4881 includes the SilcServerCommandReplyContext if the command was
4882 called as pending command callback from the command reply.
4883 Otherwise it is NULL. When called as pending the status of the
4884 command reply will be checked and if it was erronous the
4885 error will be sent to the original sender of the command.
4886 This way the client always receives the error messages even
4887 though the server was actually the one who received the error
4888 when it resent the command to router, for example. Affected
4889 files silcd/command[_reply].[ch].
4891 * Fixed sending WHOWAS command's error message to client if
4892 the requested client could not be found. It was missing.
4895 * Changed the CMODE and CUMODE commands reply arguments in the
4896 protocol specification. The Channel ID is now sent in both
4897 of the commands to identify the channel. Implemented this
4898 new feature to the client and server. Affected files
4899 lib/silcclient/command_reply.c and silcd/command.c.
4901 * Made better checks for invite and ban lists in the JOIN
4902 command in server. Affected file silcd/command.c.
4904 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4906 * The server now performs the incoming host IP/DNS lookup
4907 using the silc_socket_host_lookup and thus does not block
4908 the server anymore. Affected file silcd/server.c.
4910 * Completed the multi-thread support for SILC Scheduler in
4911 the lib/silcutil/silcschedule.c.
4913 * Fixed the configure.in.pre to detect the pthread correctly
4916 * Fixed a deadlock in silc_task_queue_wakeup in the file
4917 lib/silcutil/silctask.c.
4919 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4921 * Added new function silc_schedule_wakeup that is used in
4922 multi-threaded environment to wakeup the main thread's
4923 schduler. It needs to be used when a thread adds a new task
4924 or removes a task from task queues. After waking up, the
4925 scheduler will detect the task queue changes. If threads
4926 support is not compiled in this function has no effect.
4927 Implemented the wakeup mechanism to both Unix and WIN32
4928 systems. Affected files are lib/silcutil/silcschedule.[ch],
4929 lib/silcutil/unix/silcunixschedule.c and the
4930 lib/silcutil/win32/silcwin32schedule.c.
4932 * Added new function silc_task_queue_wakeup to wakeup the
4933 scheduler by the specified task queue. Affected file
4934 lib/silcutil/silctask.[ch].
4936 * The silc_socket_host_lookup_start now wakes up the scheduler
4937 after adding the timeout task. Affected file is
4938 lib/silcutil/silcsockconn.c.
4940 * The silc_socket_host_lookup is synchronous now if the threads
4941 support is not compiled in. However, the callback is still
4942 called asyncronously through the scheduler, anyway. Affected
4943 file lib/silcutil/silcsockconn.c.
4945 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4947 * Added new function silc_socket_host_lookup to perform
4948 asynchronous IP and FQDN lookups for the socket connection.
4949 Affected files lib/silcutil/silcsockconn.[ch].
4951 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4953 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4954 that may or may not compile the mutex support in.
4956 Changed the silc_mutex_alloc interface. It allocates the
4957 mutex now to the sent pointer and returns TRUE or FALSE.
4959 Affected file lib/silcutil/silcmutex.h.
4961 * Wrote the SILC Task Queue interface to support multi-threads.
4962 Affected file lib/silcutil/silctask.[ch].
4964 * Wrote the SILC Scheduler to support multi-threads. Affected
4965 file lib/silcutil/silcschedule.c.
4967 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4969 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4970 in lib/silcutil/win32/.
4972 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4974 * Defined SILC Mutex API and SILC Thread API and implemented
4975 them for Unix. Affected files are
4976 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4977 lib/silcutil/unix/silcunixmutex.c and
4978 lib/silcutil/unix/silcunixthread.c.
4980 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4982 * Fixed the silc_server_remove_clients_by_server's channel
4983 key re-generation. The hash table handling was incorrect
4984 and would not work with many channels. Affected file is
4987 * Fixed some memory leaks around the server code.
4989 * Rewrote the silc_server_get_users_on_channel to support IPv6
4990 based Client ID's. Affected file silcd/server.c.
4992 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4993 specification. However, a separate document must be written
4994 to define the detailed signing procedure and the payload
4995 associated with the flag. Defined the flag to the
4996 lib/silccore/silcchannel.h as well.
4998 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5000 * Changed the dynamic tables to static size tables in the
5001 lib/silccrypt/silchmac.c.
5003 * Removed GCC dependencies from the code. A patch by cras.
5005 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5007 * Do not show the error "Error receiving packet bla bla"
5008 in server if it really was not an error (-2 means that reading
5009 is pending). Affected file silcd/server.c.
5011 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5013 * Fixed a possible crash in silc_server_remove_clients_by_server
5014 in silcd/server.c. Fixed there also some memory leaks.
5016 * Fixed the silc_idlist_replace_client_id. It could replace
5017 wrong key in the hash table. Affected file silcd/idlist.c.
5019 * Do not check whether there are global users on the channel
5020 if the channel->global_users is FALSE. Affected functions
5021 silc_server_remove_from_one_channel and
5022 silc_server_remove_from_channels in silcd/server.c. Also,
5023 do not check if the removed client is local as we can be
5024 sure that global client was not removed from the channel
5025 and checking for global users is not needed.
5027 * The silc_server_remove_clients_by_server now re-generates
5028 the channel keys correctly for those channels that had
5029 clients removed from them. Affected file silcd/server.c.
5031 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5033 * Found the reason of random crashes in the server. We weren't
5034 ignoring the SIGPIPE signal (which can be sent in write())
5035 and it crashed the server. Affected file silcd/silcd.c.
5037 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5039 * Assure that sock->user_data is not NULL in the function
5040 silc_server_packet_send in silcd/packet_send.c.
5042 * Disconnect the remote connection if it could not be added
5043 to any ID lists in the server. The affected file is
5046 * Check in silc_server_packet_send[_real/dest] that the
5047 socket is not disconnecting and ignore the data if it is.
5048 Affected file silcd/packet_send.c.
5050 * Define inline to __inline on native WIN32 compilation.
5051 Affected file includes/silcwin32.h.
5053 * Added some explicit type casts for inline code since MSVC
5054 require them. Affected files lib/silcutil/silcbuffer.h,
5055 lib/trq/silcdlist.h and lib/trq/silclist.h.
5057 * Print warning in log files from now on if the packet
5058 decryption fails. Affected file silcd/server.c.
5060 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5062 * Changed the `say' client operation's interface to accept
5063 new `type' argument to indicate the type of the message sent
5064 by the library. The application may filter the library's
5065 messages according the type. The affected file is the
5066 lib/silcclient/silcapi.h.
5068 * Added two new functions to lib/silcclient/silcapi.h:
5069 silc_client_del_client and silc_client_del_client_by_id.
5070 Affected file lib/silcclient/idlist.c.
5072 * Moved the clientincludes.h from includes/ to silc/ and
5073 serverincludes.h from includes/ to silcd/.
5075 * The modes for the CMODE and CUMODE are now passed as
5076 uint32 for application with COMMAND_REPLY. The affected
5077 file is lib/silcclient/command_reply.c.
5079 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5081 * /WHOIS without arguments shows client's own information.
5082 Affected file lib/silcclient/command.c.
5084 * Changed PING to not accept any arguments. The specs
5085 says that client can ping only the connected server so
5086 requiring an argument is not needed. Affected file is
5087 lib/silcclient/command.c.
5089 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5091 * Fixed a fatal bug in private message sending and reception
5092 encryption and decryption when using private message keys.
5093 The implementation was incorrect and did not follow the
5094 specification. It causd that some of the message were
5095 lost since it did not use the sending and receiving keys
5096 as the protocol suggests. This has been fixed and will cause
5097 incompatibilities with older clients when sending private
5098 message encrypted with private message keys. Affected files
5099 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5100 and various other in Irssi SILC Client.
5102 Added `responder' boolean argument to the functions
5103 silc_client_add_private_message_key[_ske] to indicate when
5104 the key is added as responder or initiator of the key
5107 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5109 * Removed the silc_ske_check_version function and created
5110 a SilcSKECheckVersion callback. Added also a function
5111 silc_ske_set_callbacks that is now used to set all SKE
5112 callbacks. The callback functions are not given to
5113 the SKE functions anymore, but this function is used to
5116 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5118 * Added `silc_version' argument to the silc_client_alloc
5119 to define the version of the application for the library.
5120 The library will use the version string to compare it
5121 against the remote host's (usually a server) version
5122 string. Affected file lib/silcclient/silcapi.h
5124 * Added the KE protocol context to Key Agreement context
5125 in client library so that we can abort the SKE if it
5126 is in process when we get timeout. Affected file is
5127 lib/silcclient/client_keyagr.c.
5129 * Do not resolve the client ID forever if it returns in the
5130 first time that such client does not exist. This was done
5131 for example with private message. Affected file is
5132 lib/silcclient/client_prvmsg.c.
5134 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5136 * Do not add regex.h for WIN32. The affected file
5137 includes/silcincludes.h.
5139 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5140 not work yet 100%. It generates the DLL's automatically
5141 when compiling with --with-win32 under cygwin.
5143 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5145 * lib/contrib/regex.c is not compiled on WIN32.
5147 * Added silc_net_get_socket_opt function to the
5148 lib/silcutil/silcnet.h.
5150 * Added includes/silcwin32.h for WIN32 specific includes
5153 * Do not use ptime structure or any of the posix process
5154 functions on WIN32 in lib/silccrypt/silrng.c.
5156 * Added silc_gettimeofday to provide generic function
5157 for struct timeval on all platforms. Added the function
5158 to lib/silcutil/silcutil.h.
5160 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5162 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5163 library as they clearly belong there. As a plus side we
5164 can make the actual socket connection routines platform
5167 Added also new generic function silc_socket_read and
5168 silc_socket_write (that used to be silc_packet_[read/write].
5169 The implementation of these are platform specific.
5171 * Added WIN32 specific routines of silc_socket_[read/write]
5172 to lib/silcutil/win32/silcwin32sockconn.c.
5174 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5176 * Added preliminary support for native WIN32 compilation under
5177 cygwin (using the -mno-cygwin option for GCC) to the
5178 ./configure.in.pre. The --with-win32 now prepares the
5179 compilation for native WIN32.
5181 * Rewrote the SILC Scheduler interface in the file
5182 lib/silcutil/silcschedule.h. The scheduler is now context
5183 based and does not have anymore any global static scheduler.
5184 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5185 and created lib/silcutil/win32 directory for WIN32 based
5188 * Added Unix specific network routines to the
5189 lib/silcutil/unix/silcunixnet.c and the old
5190 lib/silcutil/silcnet.c includes now only generic routines.
5192 Added WIN32 specific network routines to the
5193 lib/silcutil/win32/silcwin32net.c.
5195 * Added Unix specific utility functions from the
5196 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5198 * Added WIN32 SILC Scheduler to the file
5199 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5202 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5204 * Do not handle JOIN notify in the server if the target client
5205 is not registered (idata->registered == FALSE). The affected
5206 file is silcd/packet_receive.c.
5208 * Update the nickrec->founder in event_cumode in the Irssi SILC
5209 client. Affected file irssi/src/silc/core/silc-channels.c.
5211 * Fixed the CUMODE_CHANGE notify handling in the server when
5212 server and router are announcing their clients on channels.
5213 Now the mode changes are saved and notified correctly. The
5214 affected file is /silcd/packet_receive.c.
5216 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5217 They really did not replace the cache entry in the ID Cache.
5218 Now they do that. Affected file silcd/idlist.c.
5220 * Fixed the KICK notify handling in the Irssi SILC client to
5221 update the channel records so that the kicked client does not
5222 appear to be on the channel. The affected file is
5223 irssi/src/silc/core/silc-channels.c.
5225 * Always update the conn->current_channel when executing command
5226 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5228 * Fixed the KILL notify handling in Irssi SILC client to remove
5229 the killed client on all channels.
5231 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Fixed the silc_parse_command_line to remove extra spaces
5234 from the start and end of the arguments. Affected file is
5235 lib/silcutil/silcutil.c.
5237 * Cancel and free any active protocol in the function
5238 silc_server_close_connection. Affected file silcd/server.c.
5240 * Cancel and free any active protocol in the function
5241 silc_client_close_connction. Affected file is
5242 lib/silcclient/client.c.
5244 * Do not execute the KILL command for clients that are in
5245 history (ie. they are not in the network). Affected file is
5248 * Fixed KILL notify handling, client does not crash anymore.
5249 Affected file irssi/src/silc/core/silc-channels.c.
5251 * Reduced the default packet buffer size from 2048 to 1024 in
5252 lib/silccore/silcpacket.c.
5254 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5255 counter to the SKE context that is incresed when the SKE library
5256 performs async operation outside the library. If the outside
5257 process frees the SKE context and FREED status will be set
5258 and the library will detect after the sync operation that the
5259 libary is freed. The affected files are
5260 lib/silcske/silcske[_status].[ch].
5262 * Resolve the client entry information in the function
5263 silc_client_channel_message to assure that NULL pointer is not
5264 passed as client entry to the application. */
5266 * Fixed the task timeout calculation to assure that there is
5267 never negative timeouts. The affected file is
5268 lib/silcutil/silcschedule.c.
5270 * Fixed the channel user mode notification sending in server.
5271 It was sent point-to-point to the router (or to server by router)
5272 but it needs to be destined to a channel. The routines now
5273 supports sending the channel user mode notifys to the channels
5274 when announcing clients and channels. Affected files are
5275 silcd/server.c and silcd/packet_receive.c.
5277 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5278 It did not actually replace the old channel entry in the cache.
5279 Affected file lib/silcclient/client_notify.c.
5281 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Fixed a possible crash in silc_packet_send_prepare. It now
5284 assures always that there is enough space in the buffer and
5285 at the tail area of the buffer (for MAC).
5287 Fixed the inbound buffer reallocation in silc_packet_read.
5288 It was old code and did not handle the reallocation correctly.
5291 The affected file is lib/silccore/silcpacket.c.
5293 * Fixed buffer overflow in silc_parse_nickname in the file
5294 lib/silcutil/silcutil.c.
5296 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * make install generates new server keys only if there is not
5301 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5304 Added check that if the NOREPLY is set then we will not send
5305 the away message. This avoids infinite loop of away messages
5306 if both clients are away. The affected file is
5307 lib/silcclient/client_prvmsg.c.
5309 * Fixed client crash if /NICK was given without arguments.
5310 Affected file lib/silcclient/command.c.
5312 * Server does not send the invite list in INVITE command back
5313 to the client if the list was not altered. Added this notion
5314 to the protocol spec as well. Affected file silcd/command.c.
5316 Fixed possible crash in INVITE command by checking the
5317 value of silc_server_get_client_route command.
5319 * Fixed the INVITE notify type handling. The arguments are now
5320 taken in correct order and client does not crash. The affected
5321 file is irssi/src/silc/core/silc-channels.c.
5323 Removed the "Inviting xxx to channel" message from the
5324 client library away and let the application handle it.
5325 Affected file lib/silcclient/command.c. Added that message
5326 to Irssi SILC client's message formats.
5328 * Fixed CMODE command crash in client. It now checks the
5329 amount of arguments correctly and does not crash. The affected
5330 file is lib/silcclient/command.c.
5332 * Do not create new channel automatically in silc_channels_join
5333 but check whether the channel by that name already exists.
5334 Affected file irssi/silc/core/silc-channels.c.
5336 * Do not send the SERVER_SIGNOFF to router if the disconnected
5337 entity was the router. Affected file silcd/server.c.
5339 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5340 SILC client as it was missing from there.
5342 Added the handling of the KICK notify to the Irssi SILC client
5343 as it was missing. Added "you have been kicked" message to
5344 Irssi SILC client's message modules formats.
5346 Added the handing of the KILL notify to the Irssi SILC client
5347 as it was missing. Added the kill message module formats
5350 The affected file is irssi/src/silc/core/silc-channels.c.
5352 * The router did not save the channel mode the server announced.
5353 Affected file silcd/packet_receive.c.
5355 * Fixed a possible crash in INFO command in server. If the
5356 server did not provide the server info it crashed. Affected
5357 file silcd/command.c.
5359 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Fixed the GETKEY command in the server to check also the
5362 global list. Otherwise the GETKEY would not work correctly
5363 in normal SILC server. Affected file silcd/command.c.
5365 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Fixed GETKEY crash, it crashed if the command did not succseed.
5369 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5372 is now real and not just an macro interface to GMP.
5374 Removed the entire GMP from the source tree and imported new
5375 NSS MPI library instead. Reason for removing GMP is that it is
5376 extremely large and compiles extremely slow. The NSS MPI
5377 is only a few files and compiles in less than 10 seconds.
5378 The speed is also about the same as GMP. The MPI is imported
5379 to lib/silcmath/mpi.
5381 If the system has GMP installed we will still use the GMP.
5382 If it is not then the NSS MPI will be compiled.
5384 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Merged a long nickname (127 characters long) crash bugfix from
5387 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5389 * Merged a freed memory reference bugfix from Irssi CVS tree.
5390 Affected file irssi/src/core/commands.c.
5392 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added the server's public key sving and verification to the
5395 server when performing the SKE. This was missing and the
5396 remote server's (or router's) public key was accepted without
5397 checking whether we have it previously or trust it at all.
5398 Affected file silcd/protocol.c.
5400 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Check in the silc_server_timeout_remote if protocol is active
5403 and make sure that the protocol's final callback is called so
5404 that all memory if freed. Affected file silcd/server.c.
5406 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * silc_server_whois_send_reply crashed the server if the nickname
5409 was 127 characters long. Affected file silcd/command.c.
5411 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Added sanity check to the silc_server_new_client. If the hostname
5414 is provided inside username then check that the provided hostname
5415 really is the same as the resolved one. If the hostname was not
5416 resolved then check it from the public key. Affected file is
5417 silcd/packet_receive.c.
5419 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5420 if the server disconnected us and the connection is not valid
5421 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5423 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5424 the library to the lib/silcutil/silcutil.[ch].
5426 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Close log file after open. Affected file
5429 lib/silcutil/silclog.c.
5431 * Check whether sock == NULL in silc_client_send_packet and return
5432 if it is. Affected file lib/silcclient/silcclient.c.
5434 * Check rec->entry == NULL in the Irssi SILC Client before
5435 sending the channel message. Affecte file is
5436 irssi/src/silc/core/silc-servers.c.
5438 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Merged a splitted window bugfix from Irssi CVS tree. The
5441 affected file is irssi/src/fe-text/textbuffer-view.c.
5443 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5444 It did not print nickname.
5446 * Improved the distributions system a bit.
5448 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5451 irssi/src/fe-text/gui-window.c.
5453 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5454 to in-active server. The affected file is
5455 irssi/src/silc/core/client_ops.c.
5457 * Resolve the client in USERS command reply if the entry does
5458 not have username resolved. The affected file is
5459 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5460 command to WHOIS command to really resolve stuff. The USERS
5461 is not used any more in any critical section so WHOIS can
5462 be used even though it might be slower than IDENTIFY.
5464 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5467 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Changed the protocol API a bit more consistent in the
5470 lib/silccore/silcprotocol.[ch].
5472 * Changed the following headers to ROBODoc format:
5474 lib/silccore/silcpayload.h
5475 lib/silccore/silcprotocol.h
5476 lib/silccore/silcsockconn.h
5478 All core library headers are now formatted.
5480 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Fixed a bug in Irssi SILC client; do not show that you are
5483 server/router operator if you really are not. Affected file is
5484 irssi/src/silc/core/client_ops.c.
5486 * Renamed silc_command_free_payload to silc_command_payload_free.
5487 Affected file lib/silccore/silccommand.h
5489 * Added silcmath.h to include the prototoypes of various routines
5490 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5493 * Changed the following headers to ROBODoc format:
5495 lib/silccore/silcchannel.h
5496 lib/silccore/silccommand.h
5497 lib/silccore/silcid.h
5498 lib/silccore/silcidcache.h
5499 lib/silccore/silcmode.h
5500 lib/silccore/silcnotify.h
5501 lib/silccore/silcpacket.h
5502 lib/silcmath/silcmath.h
5504 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Added checking to the server code not to start the server if
5507 ciphers and stuff are not configured properly. Affected files
5508 silcd/serverconfig.[h] and silcd/server.c.
5510 * Changed the layout of the header files of the public interfaces
5511 in the SILC libraries. The new layout supports ROBODoc
5512 documentation tool (and some others) so that it is easy to create
5513 a library reference manual. All the other headers and source
5514 code must still follow the CodingStyle document. Also source
5515 code must not include these ROBODoc stuffs, only the headers.
5516 Furthermore, all public interface headers must now be named
5517 by using `silc' prefix, example: silcapi.h, silccipher.h.
5518 Some files were renamed due to this. All the other headers
5519 must not be used as public interfaces. I will update the
5520 CodingStyle document later. Changed following headers, so far:
5522 lib/silcclient/silcapi.h
5523 lib/silccore/silcauth.h
5524 lib/silccore/silcprivate.h
5525 lib/silccrypt/silcdh.h
5527 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Removed silc_client_packet_send_flush from the client library
5532 as it is not needed. Affected file lib/silcclient/client.[ch].
5534 * Added printing of message of unresolved authentication method
5535 to the Irssi SILC client. Added it to the module formats.
5536 Removed the same message from the client library.
5538 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Added new distribution feature, DISTLABEL. Every distribution
5541 can define own preprocessor label that can be used in the
5542 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5543 file distributions, acconfig.h.pre and prepare.
5545 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Added Makefile.defines_int to include the actual definitions
5548 for Makefile.defines.in. Tested the new distribution system,
5549 created distributions and tested installation.
5551 * Added AWAY message printing to the Irssi SILC client. Added
5552 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5554 * Added SCONNECT command to call the SILC's CONNECT command.
5555 Cannot use CONNECT directly since Irssi uses that internally.
5556 Affected file irssi/src/silc/core/silc-servers.c.
5558 Added ACTION local command. It is same as ME command but takes
5559 the channel as mandatory argument.
5561 Rewrote some of the Irssi's help files to suite for SILC
5564 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added Makefile.defines[.in] that should for now on be included
5567 in all Makefile.am file in the source tree. That file includes
5568 all common compilation definitions for SILC source tree.
5570 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Minor changes to the ./prepare script to change the package
5573 name according the distribution name to the configure.in.
5575 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Created new distribution system. Added file `distributions'
5578 that defines all the distributions that can be created out of
5579 the SILC source tree. The ./prepare script now reads that
5580 file to determine how to prepare the distributions. The
5581 first argument to the ./prepare is the name of the distribution
5582 and second is the version of the distribution. If given
5583 without arguments it creates the default (toolkit) distribution
5584 with the default version (defined in ./prepare).
5586 All Makefile.am files that are subject to the distributions
5587 are now named as Makefile.am.pre. These are ./Makefile.am
5588 and lib/Makefile.am. Others may be changed later.
5590 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added invite list, ban list, some key management and connection
5593 error message printing to module formats in the Irssi SILC client.
5595 * Added new silc_client_set_away_message to set the away message
5596 that is back to the person who sent private message. The
5597 affected file lib/silcclient/silcapi.h and the
5598 lib/silcclient/client_prvmsg.c.
5600 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Fixed the private message sending in the Irssi SILC client,
5603 added local command KEY to the Irssi SILC client.
5605 Added key management and key agreement message formats to the
5606 irssi/src/fe-common/silc/module-formats.[ch].
5608 Added USERS (alias WHO) printing, server/router operator
5609 indication and LIST command printing to the module formats.
5611 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Fixed channel joining notify handling, cumode notify handling
5614 from Irssi SILC client.
5616 * Added SILC specific module-formats to the Irssi SILC client so
5617 that SILC specific message hilighting, colors etc is possible.
5618 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5620 Added channel mode, channel user mode, actions, notices,
5621 whois and whowas printing to the the module-formats.c.
5623 * Fixed a bug in channel deletion in the server. The channel
5624 is not left to the cache even if the channel founder auth mode
5625 is set when there are no users anymore on the channel. Affected
5626 file silcd/server.c.
5628 * The silc_net_localhost now resolves the entire hostname including
5629 the domain name. Affected file lib/silcutil/silcnet.c.
5631 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Changed the ask_passphrase client operation to be ascynchronous.
5634 It has now a completion callback and a context that the
5635 application must call after it has got the passphrase from
5636 the user. Affected files lib/silcclient/silcapi.h,
5637 lib/silcclient/protocol.c, lib/silcclient/command.c and
5640 Added SilcAskPassphrase callback that the application calls
5641 to deliver the passphrase to the library.
5643 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5644 The public key verification and especially a certificate
5645 verification is asynchronous procedure.
5647 Added new SILC_SKE_STATUS_PENDING status to indicate the
5648 request is pending and a callback will be called to finalize
5651 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5652 indicate that remote end did not send its public key (or
5653 certificate), even though we require it. Added check for this
5654 condition in the SKE. This was a security bug, now fixed.
5656 Defined new SilcSKEVerifyCbCompletion callback that is called
5657 when the verification process is completed.
5659 The affected files lib/silcske/silcske_status.h and
5660 lib/silcske/silcske.[ch].
5662 * Changed the verify_public_key client operation to be async
5663 as well. Defined SilcVerifyPublicKey callback that is used to
5664 indicate the success of the public key verification process.
5666 Changed the server and client to use the new async client
5669 * Changed the Irssi SILC client's internal scheduler to be called
5670 twice as many times as it used to be. As a result the client
5671 should be a bit faster now. Affected file is
5672 irssi/src/silc/core/silc-core.c.
5674 * Added support to Irssi SILC client of asynchronous public key
5675 verification and passphrase inquiry. Affected file is
5676 irssi/src/silc/core/silc-core.c.
5678 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Do not say "You have left channel %s" in client library.
5681 Moved it to the application. Affected files are
5682 lib/silcclient/command.c and silc/client_ops.c.
5684 * Fixed silc_client_get_clients. Command context was not
5685 duplicated and was freed memory in the callback. Affected
5686 file lib/silcclient/idlist.c.
5688 * Do not say "you are now talking..." on JOIN command in the
5689 client library. The appliation must handle it.
5691 * Do not say ".. changed topic to" in command reply in the
5692 client libary. The application must handle it.
5694 * Fixed TOPIC command sending in the client library.
5696 * Fixed a memory leak in silc_client_command_free in the file
5697 lib/silcclient/command.c.
5699 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5701 * Imported a modified version of Irssi client to the source tree.
5702 The Irssi will be used to create a new client called
5703 Irssi SILC. Imported to irssi/.
5705 Added silc_core_init_finish function to the Irssi. Affected
5706 file irssi/configure.in.
5708 A lot changes in the Makefile.ams around the irssi tree.
5710 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Do not rehash if the new size is same as the old size of the
5713 hash table, in the silc_hash_table_rehash*. The affected file
5714 lib/silcutil/silchashtable.c.
5716 * Replaced hash_table_del_by_context calls from the server
5717 (when channel->user_list and client->channels) to the
5718 hash_table_del as it is sufficient and faster.
5720 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added silc_hash_table_list, silc_hash_table_get and the
5723 SilcHashTableList structure to provide an alternative way to
5724 traverse the hash table. The affected files are
5725 lib/silcutil/silchashtable.[ch].
5727 * Changed the server's idlist routines to use the hash table
5728 routines to optimize the code.
5730 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Replaced the client entry's `channel' list and channel entry's
5733 `user_list' list to hash tables for optimized lookup. Changed
5734 the code to use the hash table interface around the code.
5735 Affected file lib/silcd/idlist.[ch].
5737 * Added `auto_rehash' boolean argument to the function
5738 silc_hash_table_alloc to indicate whether the hash table should
5739 auto-rehash when it thinks is appropriate time. It will
5740 increase the hash table size if the there is twice as much
5741 entries in the table than the size of the table, and will
5742 decrease the size if there are twice as less entries than
5743 the size of the table.
5745 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5749 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * silc_idcache_purge_by_context deletes the entry now by context
5752 as it is supposed to do. Affected file lib/silccore/idcache.c.
5754 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5755 client is not anymore valid (WHOWAS givens the info) and not
5756 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5758 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Removed the `data' and `data_len' arguments from the ID Cache
5761 interfaces and added `name' argument. ID Cache does not handle
5762 anymore the binary data only a names associated with given ID.
5764 * When hashing a Client ID with silc_hash_id the entire ID is
5765 not hashed anymore, instead only the hash of the Client ID is
5766 hashed. This way we can access the Client ID from the cache
5767 with Client ID but with the hash of the ID (which is a hash of
5768 the nickname) as well without any difference in performance.
5770 Added also silc_idcache_find_by_id_one_ext to do one on one
5771 searching when we have the actual ID. Added also function
5772 silc_hash_client_id_compare. The affected files are
5773 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5775 * When hashing the name associated with a ID it is always done
5776 in lowercase. This way we can access the cache without worrying
5777 about case-sensitivity, even though, for example nicknames are
5780 * Fixed a bug in server with channel message sending. It put
5781 wrong ID type as destination ID. The affected file
5782 silcd/packet_send.c.
5784 * silc_idcache_del_by_context now deletes from all hash tables
5785 by context. Affected file lib/silccore/idcache.c.
5787 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Changed the client library to use the new ID Cache interface.
5790 Changes around the source tree.
5792 * Added silc_hash_table_rehash_ext to rehash with specific
5793 hash function. Affected file lib/silcutil/silchashtable.[ch].
5795 * Added silc_hash_string_compare to compare two strings in the
5796 hash table. Affected file lib/silcutil/silcutil.[ch].
5798 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added new function silc_idcache_del_by_context into the
5801 lib/silccore/idcache.[ch].
5803 * Changed the server's ID list routines to use the new ID Cache
5804 interface. Changes around the source tree.
5806 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Added silc_hash_table_del[_by_context]_ext functions in to the
5809 lib/silcutil/silchashtable.[ch].
5811 Removed silc_hash_table_find_all* routines and added new
5812 silc_hash_table_find_foreach to replace them.
5814 Added silc_hash_table_replace_ext function as extended
5815 replacing function. Separated the simple hash table interface
5816 from the extended hash table interface in the file
5817 lib/silcutil/silchashtable.h.
5819 * Fixed minor bugs and changed it to use some of the new
5820 hash table functions in lib/silccore/idcache.c
5822 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Added new function silc_hash_table_find_all to return all keys
5825 in the hash table by the specified key. As the hash table is
5826 collision resistant it also makes it possible to have several
5827 duplicate keys in the hash table. This function may be used to
5828 find all of the keys from the hash.
5830 Added user_context arguments to the SilcHashFunction,
5831 SilcHashCompare and SilcHashDestructor to deliver user specified
5834 Added new fuctions silc_hash_table_find[_all]_ext to do
5835 extended lookup with specified hash and compare functions and
5836 specified user contexts.
5838 Added new function silc_hash_table_add_ext to add the key
5839 with specified hash function and user context.
5841 Added new function silc_hash_table_foreach to traverse all
5842 entrys in the hash table. Added SilcHashForeach callback
5845 Added new function silc_hash_table_del_by_context to delete
5846 the entry only if the context associated with the key matches.
5848 Affected files are lib/silcutil/silchashtable.[ch].
5850 * Removed silc_hash_[server/client/channel]_id and added just
5851 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5852 silc_hash_id_compare to compare two ID's using as the hash table
5853 comparison function. Added also silc_hash_data to hash
5854 binary data and silc_hash_data_compare to compare it.
5856 * Removed silc_idlist_find_client_by_hash as it is not needed
5857 anymore. Affected file silcd/idlist.[ch].
5859 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5860 to use internally the SilcHashTable. The new ID Cache is a lot
5861 faster than the old one. Some of the ID Cache interface was also
5862 rewritten and obsolete and stupid functions were removed.
5864 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added entry_count field to the SilcHashTable to keep the number
5867 of the entries in the table. Implemented the function
5868 silc_hash_table_rehash. Added new function
5869 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5871 Fixed a minor bug in silc_hash_table_free.
5873 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5874 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5875 into the lib/silcutil/silcutil.[ch].
5877 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Implemented a collision resistant hash table into the
5880 lib/silcutil/silchashtable[ch]. See the header and the source
5881 for the SilcHashTable API.
5883 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Merged dotconf version 1.0.2 into lib/dotconf.
5887 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Do not compile anything in lib/silcsim/* if the SIM support
5890 is not enabled. The tree should now compile without problems
5893 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Compiled the SILC under cygwin. Compiled and tested briefly
5896 without problems. More tests needed. The SIMs didn't compile
5899 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5901 * Fixed possible crash in silc_get_username in the
5902 lib/silcutil/silcutil.c.
5904 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Fixed a va_arg in silc/client_ops.c.
5908 * Oops, RC5 routines were named AES and caused some problems
5909 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5911 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Added new SilcIDIP structure into the lib/silccore/id.h and
5914 replaced the old `ip' fields from all SILC ID's to that type.
5915 This is a step towards IPv6 support.
5917 The silc_id_get_len takes now the ID as an extra argument.
5918 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5919 both IPv4 and IPv6 based ID's.
5921 The affected files are lib/silccore/id.[ch] and other files
5922 around the tree using these routines.
5924 * Removed the ID length arguments in server from various
5925 silc_server_send_notify_* routines -> they are not needed
5928 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Fixed memory leak in silc_encode_pem_file in the file
5931 lib/silcutil/silcutil.c.
5933 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Check minor version as well in the SKE. Affected files are
5936 silcd/protocol.c and lib/silcclient/protocol.c.
5938 * Added --identifier option to the server so that an identifier
5939 can be when creating the public key for the server. Affected
5940 file is silcd/silcd.c.
5942 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5943 lib/silccrypt/silcpkcs.c.
5945 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Register default ciphers and stuff when using -C option with
5948 the server. Affected file sildc/silcd.c.
5950 * Put back the servers public key filename format, it is better
5951 than the new one. For now, the client keys are saved with the
5952 new filename format. The affected file silc/client_ops.c.
5954 * Implemented the Cipher API for the rest of the ciphers that
5955 did not implement it or implemented it the wrong way.
5957 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Register default ciphers and stuff when using the -S option
5960 in the client. Affected file silc/silc.c. Same also when
5961 creating new key pair with -C option.
5963 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Fixed the silc_verify_public_key client operation function to
5966 save the public keys differently. The fingerprint is now
5967 used as filename and not the hostname. This way also the
5968 client keys are saved uniquely and not with hostnames. The
5969 affected file is silc/client_ops.c.
5971 * Trimmed the silc_hash_fingerprint function to remove extra
5972 whitespaces from the end of the fingerprint. The affected
5973 file is lib/silccrypt/silchash.c.
5977 * Added silc_cipher_register_default function to register all
5978 default ciphers. It can be used when configuration files
5979 does not exist and the application does not want any specific
5980 ciphers in any specific order.
5982 The SilcDList is now used as silc_cipher_list dynamically
5983 allocated cipher list. Removed the static list all together
5984 and now all ciphers must be allocated to the dynamic list.
5985 The silc_cipher_alloc routine was changed to check only the
5988 All silc_cipher_* routines that used to return int returns
5991 The affected files lib/silccrypt/silccrypt.[ch].
5993 * The same thing was done to silc_hash_* as for silc_cipher_*
5994 routines. Affected files lib/silccrypt/silchash.[ch].
5996 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5997 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5998 Added also silc_pkcs_[un]register[_default] functions.
5999 Removed the data_context from the PKCS API.
6001 * Added silc_hmac_register_default function to register default
6002 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6003 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6004 to unregister all hmacs at once.
6006 * Register the default ciphers, hash functions, PKCSs and HMACs
6007 if client's configuration file does not exist. The affected
6010 * The client did not load the hash functions from the SIM
6011 modules at all. Added support for this. Affected file is
6012 silc/clientconfig.c.
6014 * When decoding public key with silc_pkcs_public_key_decode, check
6015 the supported algorithm only if PKCS are registered. Affected
6016 file lib/silccrypt/silcpkcs.c. The same was done with the
6017 silc_pkcs_private_key_decode.
6019 * Fixed the SILC List routines to keep the list always in order.
6020 It used to change the list's order when traversing the list but
6021 not it preserves the order. Affected file lib/trq/silclist.h.
6023 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added the client library to use the SilcSocketConnection's
6026 reference counter (by silc_socket_dup) to prevent the bug that
6027 the socket object may be freed underneath async operation.
6029 * The name resolv library checking fixes in the configure.in.pre.
6032 * Created new version of the protocol drafts for future
6033 development. The -03 drafts are the ones that will be changed
6034 in the trunk now and the -02 will remain as they are.
6036 * Send list of CUMODE notifys to the router when announcing
6037 the channel users to the router. Affected file silcd/server.c.
6038 If the router receiving channel founder CUMODE for a channel
6039 that already has channel founder it will send CUMODE notify
6040 to the sender to remove the channel founder rights from the
6041 announced client. Affected file silcd/packet_receive.c.
6043 * The CUMODE notify may now use Server ID as well as the entity
6044 who changes the mode. Updated protocool specs.
6046 * Updated INSTALL and README files.
6048 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * New web pages in the http://silc.pspt.fi. The pages was
6055 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Implemented the [DenyConnectin] config section in the server.
6058 Added silc_server_config_denied_conn to check whether incoming
6059 connection is denied. Affected file silcd/serverconfig.[ch].
6061 * Do not check the ports when checking the incoming configuration
6062 data if the port is 0, meaning any. Affected file is
6063 silcd/serverconfig.c.
6065 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Fixed buffer overflow in silc_string_compare in the file
6068 lib/silcutil/silcutil.c.
6070 * Fixed double free in silc_server_command_leave in the file
6073 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Fixed the version checking in the server. Affected file is
6078 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Fixed the configuration data fetching when accepting new
6081 connections in the server. Affected file silcd/server.c.
6083 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added `sender_entry' argument to the function
6086 silc_server_packet_relay_to_channel so that we can check
6087 whether some destination actually belongs to the same route
6088 the sender belongs (ie, we must not resend the packet to the
6089 sender). Affected file silcd/packet_send.[ch].
6091 * Added `servername' field to the SilcClientEntry in the server
6092 to hold the name of the server where client is from. Affected
6093 file is silcd/idlist.h.
6095 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Moved the channel message encrypting in the router betwen
6098 router connections from silc_server_channel_message to the
6099 silc_server_packet_relay_to_channel since we want to check
6100 whether we have anybody channel before encrypting anything.
6101 Affected files silcd/packet_[receive/send].c.
6103 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Fixed the [AdminConnection] server config section to support
6106 multiple entries. Affected file silcd/serverconfig.c.
6108 * Added support into the server to check the validity of the
6109 incoming connection before executing any KE or authentication
6112 * The connection configuration is now saved to the KE and
6113 connection auth protocol contexts and not fetched anymore in
6114 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6116 * The local hosts listenning address and port is also resolved
6117 now when starting the server. We want to have the socket object
6118 to include the real address and port for the listener. Added
6119 new function silc_net_check_local_by_sock into the files
6120 lib/silcutil/silcnet.[ch].
6122 * Fixed a broadcast bug in server -> do not broadcast if we
6125 * Fixed a routing bug. Do not route broadcast packets ever.
6126 Broadcast packets must be processed always and not routed since
6127 they may be destined to some other host than yourself and thus
6128 would get routed without no good reason. Affected file is
6131 * Added function silc_server_config_is_primary_route to check
6132 whether primary router connection has been configured (a router
6133 configuration that we are initiating). If there is not, we
6134 will assume that there is only two routers in the SILC network
6135 and we will use the incoming router connection as our primary
6136 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6138 * Changed the order of the broadcasting. Broadcast _after_ the
6139 packet has been processed not before. Affected file is
6142 * Fixed a [ClientConnection] parsing bug. The port was never
6143 parsed correctly thus resulting to port 0. Affected file
6144 silcd/serverconfig.c.
6146 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6147 argument and did not set the broadcast packet flag. Affected
6148 file silcd/packet_send.c. Fixed same bug in the function
6149 silc_server_send_notify as well.
6151 * If we receive NEW_ID packet for our own ID in the server, ignore
6154 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Removed the nickname from the Private Message Payload.
6159 Updated the code and the protocol specs.
6161 * Updated protocol specs for submitting to the IETF.
6163 * Tweaked the Random Number Generator a bit. Affected file
6164 lib/silccrypt/silcrng.c. Exported a new function
6165 silc_rng_[global]_add_noise which can be used to add more
6168 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Do not parse packets with different timeout when protocol
6171 is active -> may cause problem with rekey. Affected file
6174 * When server receives signoff notify it must not create
6175 new channel key if the client is on any channels since the
6176 sender of the signoff notify will create it.
6178 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Added printing of error messages during SKE protocol from the
6181 failure packet sent by server during SKE. Affected file
6184 * Removed the client's failure_callback handling with timeout
6185 and handle it immediately when received.
6187 * The SKE library returned wrong type in SUCCESS and FAILURE
6188 packets. They must be 32 bit MSB not 16 bit MSB.
6190 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Ok, rewrote the logic of the re-key and now it seems to work.
6193 I tested it on high traffic with frequent re-keys without
6194 problems. Added hmac_receive (and renamed hmac to hmac_send)
6195 in SilcClientConnection in lib/silcclient/client.h and
6196 in SilcIDListData in silcd/idlist.h. Also, removed the
6197 SilcPacketParserContext's cipher and hmac fields as they are
6198 not needed anymore and actually caused some problems when
6199 the ciphers and hmac's changed underneath the packet parser.
6201 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * If re-key protocol is active then process the incoming packets
6204 synchronously since we must assure that icoming packets encrypted
6205 with the old key is processed before the new keys is set to
6206 use. This is true other packets than for REKEY packets.
6207 Affected file silcd/server.c. The same was done to client library
6208 as well, affected file lib/silcclient/client.c.
6210 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Fixed bug in client and server to accept the force send if
6213 the packet is send from silc_[server/client]_packet_process
6214 function. Otherwise the packets are never delivered, oops.
6216 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Disable force sending of packets when REKEY protocol is active.
6219 We must assure that no packet is sent directly when rekey is
6220 performed. All packets must be sent through packet queue.
6221 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6222 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6223 function is silc_[server/client]_packet_send_real to check
6226 * Replaced the SIM paths from example config files to
6227 /usr/local/modules. Also, make install creates now
6228 /usr/local/silc/logs directory to hold all the SILC server
6231 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Made the configure.in.pre work on Solaris. Patch by salo.
6235 * Made all ciphers compatible with non-x86 machines. Defined
6236 CBC mode macros into lib/silccrypt/ciphers_def.h.
6238 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Fixed the make install.
6242 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * When MAC computation fails the silc_packet_decrypt returned 0
6245 even though it was supposed to return -1. Fixed this. The
6246 affected file is lib/silccore/silcpacket.c.
6248 * Do not replace the config files in /etc/silc (in make install)
6249 if they already exist. Affected file ./Makefile.am.
6251 * Do not send re-key packets immediately but through packet queue.
6252 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6254 * Changed silc_net_check_host_by_sock to return FALSE if the
6255 IP/DNS could not be resolved. Though, it returns the IP address
6256 now even if it could not resolve it (but returns also FALSE).
6257 Affected file lib/silcutil/silcnet.[ch].
6259 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Added silc_pkcs_decode_identifier to decode the public key's
6262 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6263 Added also silc_pkcs_free_identifier. Added also new context
6264 SilcPublicKeyIdentifier.
6266 * Added -S option to the silc client. It is used to dump the
6267 contents of the specified public key file.
6269 * Changed the PKCS api to return the public key length when
6270 setting the public key.
6272 * Fixed a fatal bug in the public and private key file loading.
6273 Affected file lib/silccrypt/silcpkcs.c.
6275 * Execute the packet parsing for client with zero (0) timeout
6276 if the protocol is active. Affected file silcd/server.c.
6278 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Made the key generation options to the silcd program. Added
6281 -C option, equivalent to client's option.
6283 * Added new [ServerKeys] config section to the server. It
6284 configures the server's public and private key.
6286 * Defined generic Public Key Payload into the protocol
6287 specification to send specific type of public keys and
6290 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6291 public key or certificate.
6293 * Implemented the GETKEY command to the server and to the
6294 client library and on user interface.
6296 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Made preliminary `make install' work.
6300 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added SilcServerRekey context into silcd/idlist.h.
6304 * Added the PFS support as defined in the specification to the
6305 SKE protocol. Affected files lib/silcske/*.c.
6307 * Added `ske_group' field to the SilcServerRekey context to hold
6308 the number of the SKE group that is used with PFS in re-key.
6309 Affected file silcd/idlist.h.
6311 * Added PFS re-key support to the server. Affected file is
6314 * Added silc_protocol_cancel to cancel execution of the next
6315 state of the protocol. Affected file is
6316 lib/silccore/silcprotocol.[ch].
6318 * Added the re-key support with and without PFS to the client
6319 library. Re-key is performed once in an hour, by default.
6321 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6322 Added silc_client_rekey_callback and silc_client_rekey_final.
6323 Affected files are lib/silcclient/protocol.[ch] and
6324 lib/silcclient/client.[ch].
6326 * Removed the `hmac_key' and `hmac_key_len' fields from the
6327 SilcClientConnection structure; not needed. Affected file is
6328 lib/silcclient/client.h.
6332 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Do not ask whether user wants to use the negotiated private key
6335 for private messages, just use it. Affected file is
6336 silc/local_command.c.
6338 * Added `send_enc_key' and `enc_key_len' fields to the
6339 SilcIDListData structure since they are needed in the re-key
6340 phase. Affected file is silcd/idlist.[ch].
6342 * Implemented the simple re-key protocol into the server.
6343 Affected files silcd/server.c and silcd/protocol.[ch]. The
6344 re-key will be performed once in an hour, by default.
6346 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6347 Added silc_server_rekey, silc_server_rekey_callback and
6348 silc_server_rekey_final.
6350 * Removed Tunneled flag from the protocol. Updated the code
6351 and the specifications.
6353 * Adde `pfs' field to the SilcIDListData to indicate whether
6354 the PFS is to be performed in the re-key. Affected file is
6357 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6360 int64 of at least the xintXX size. If void * is less that 4
6361 bytes uint32 * will be used. Defined bool as boolean.
6363 * Changed _ALL_ unsigned long and unsigned int to uint32,
6364 unsgined short to uint16 in the source tree.
6366 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6367 not handle clients that has entry->data.registered == FALSE.
6368 They are not in the network anymore. Affected file is
6371 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Implemented the sending of the SERVER_SIGNOFF notify in the
6374 server. Affected file is silcd/server.c.
6376 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6377 Added also silc_notify_payload_encode_args into the
6378 lib/silccore/silcnotify.[ch].
6380 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6381 Affected file silcd/packet_receive.c.
6383 * Implemented the SERVER_SIGNOFF notify handling in the client
6384 library. Affected file lib/silcclient/client_notify.c. Also,
6385 implemnted the printing of the SERVER_SIGNOFF info to the
6386 application. Affected file silc/client_ops.c.
6388 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6389 if the deleting was successful. Affected file silcd/idlist.[ch].
6391 * Added support for public key authentication in the connection
6392 authentication protocol in the client library. Affected file
6393 lib/silcclient/protocol.c.
6395 * Changed the server's silc_idlist_get_clients_by_* interface
6396 to support already allocated array so that new entries may be
6397 added to pre-allocated array. Affected file silcd/idlist.[ch].
6398 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6399 and command replies.
6401 * All command reply functions in the server now calls the
6402 pending command callback even if error occured. This way the
6403 error will be delivered to the client as well. Affected files
6404 silcd/command.c and silcd/command_reply.c.
6406 * Fixed INFO command to return local server's info if no server
6407 was provided. Affected file lib/silcclient/command.c.
6409 * Removed RESTART command for good. Updated the code and the
6412 * Rewrote parts of the task system. It is a bit simpler now.
6413 Removed unsued task priorities. The affected files are
6414 lib/silcutil/silctask.[ch].
6416 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Moved the USERS printing from the library to the application.
6419 Affected files lib/silcclient/command.c and silc/client_ops.c.
6421 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added channel key re-key support. The re-key is perfomed
6426 only by the router and is done once in an hour. Added `rekey'
6427 field to the SilcChannelEntry in the server. Affected files
6428 silcd/server.c and silcd/idlist.h.
6430 * Added silc_task_unregister_by_context into the file
6431 lib/silcutil/silctask.[ch].
6433 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Added SILC_UMODE_GONE mode to indicate when the client is not
6436 present in the SILC network. Added also support to the local
6437 command AWAY that will set this mode. Added support of showing
6438 "xxx is gone" in WHOIS command. The USERS command shows the
6439 gone status as well.
6441 * Fixed setting server and router operator privileges in the
6442 server's UMODE command. Affected file silcd/command.c.
6444 * Merged the SKE KE1 and KE2 payloads into one payload. The
6445 new KE payload is equivalent to the old KE2 payload.
6447 Cleaned up the SKE Start Payload parsing. It now uses the
6448 simple buffer unformatting to do the parsing. A lot faster
6451 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6452 to the SKE that is used to indicate whether both of the SKE
6453 parties should perform authentication. By default only the
6454 responder performs authentication. By setting this flag also
6455 the initiator must do authentication. By default it is unset
6456 since in normal SKE case, client to server connection, only
6457 the responder should do authentication. When doing SKE between
6458 two clients both should perform authentication. Updated the
6459 code and the protocol specs.
6461 * A little fix to IDENTIFY command in the server. Search the
6462 client first by hash not nickname. Affected file is
6465 * Fixed the silc_client_close_connection to support closing
6466 the client to client connections wihtout deleting too much
6467 data. Affected file lib/silcclient/client.c.
6469 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6470 are received if protocol used to be active but is not anymore
6471 the application would crash due to NULL pointer dereference.
6472 Affected files silcd/server.c and lib/silcclient/client.c.
6474 * Added `hash' field to the SilcClientConnection to include
6475 the hash function negotiated in the SKE protocol.
6477 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6478 to set the channel founder authentication data. A client can
6479 claim the founder rights later by providing the authentication
6480 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6481 This way the channel founder can regain the channel founder
6482 privileges even it is left the channel. This works only on
6483 local server and the client must be connected to the same
6484 server to be able to regain the founder rights. Updated the
6485 protocol specs accordingly.
6487 Added support to the CMODE command in the client to set the
6488 founder auth data. Read the README to see how to set it.
6490 Added support to the CUMODE command to claim the founder
6491 rights. Read the README to see how to do it.
6493 Added support for the founder authentication to the Channel
6494 Entry in the server. Affected file silcd/idlist.h.
6496 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6497 server's CMODE command. Affected file silcd/command.c.
6499 * Added the following new functions into lib/silccore/silcauth.[ch]:
6500 silc_auth_get_method and silc_auth_get_data.
6502 * The server now saves the remote hosts public key to the
6503 SilcIDListData pointer. Affected file silcd/protocol.c.
6505 * The normal server now does not remove the channel entry from
6506 the cache if the founder authentication data is set. It used
6507 to remove it if the founder was the last one on the channel on
6508 the server and left the channel. The auth data is saved and
6509 if the channel is re-joined later the old entry is used with
6510 the old auth data. Affected files silcd/command_reply.c and
6513 * Removed the `pkcs' field from the SilcIDListData structure
6514 in the server; it is not used. Affected file silcd/idlist.h.
6516 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Fixed packet processing on slow links. Partial packets were
6519 never re-processed because the incoming data buffer was cleared
6520 by the application. Application must not directly clear the
6521 sock->inbuf, the packet processing routines handle it. Fixed
6522 this in client library and in server.
6524 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Fixed the WHOIS and IDENTIFY send reply function to really
6527 check whether to send list or just one entry. Affected file
6530 * Cleaned up the LEAVE command's channel key distribution. The
6531 affected file silcd/command.c.
6533 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6534 can enforce the channel mode as well. In that case the ID
6535 includes the ID of the server. The code now enforces the
6536 mode change if the router have different mode than the server.
6538 * The notify client operation with CMODE_CHANGE notify can now
6539 return NULL client_entry pointer if the CMODE was not changed
6540 by client. Application must check for this.
6542 * Added <Server ID> argument to INFO command to support server
6543 info fetching by Server ID.
6545 * Added silc_server_announce_get_channel_users to get assembled
6546 packets of channel users of the specified channel. Affected
6547 file silcd/server.[ch].
6549 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6550 was freed underneath the ID Cache.
6552 * Re-announce clients when the server received CHANNEL_CHANGE
6553 notify from the router. Affected file silcd/packet_send.c.
6555 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6558 crashed since it did not handle the fact that there is no cipher
6559 called "3" and didn't check the error condition. Now fixed.
6561 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6562 flag. It can be used to send message requests.
6564 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Implemented the RESTART command in the client.
6568 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6569 notice type messages. Added notice printing to the user
6572 * The channel keys are not re-generated if the channel's mode
6573 is PRIVKEY, ie private key on the channel exists. Affected
6574 files silcd/server.c and silcd/command.c.
6576 * Fixed a little bug in channel message delivery when channel
6577 private keys are set in the server. Affected file is
6578 silcd/packet_send.c.
6580 * Changed the setting on channel->on_channel = TRUE from the
6581 silc_client_save_channel_key to the JOIN command reply. The
6582 key payload is not received if the private channel key is set.
6583 Affected file lib/silcclient/command_reply.c and the
6584 lib/silcclient/client_channel.c.
6586 * When the CMODE_CHANGE notify is sent and the channel private
6587 key mode is removed the channel key must be re-generated in
6588 other cells as well. Added this support for the router in the
6589 silcd/packet_receive.c.
6591 * Added new local command NOTICE to send notice message on
6592 channel. Affected file silc/local_command.[ch].
6594 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Added new local command ME to the client. It is used to send
6597 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6598 some action. Affected file silc/local_command.[ch].
6600 * Changed channel_message and private_message client operations
6601 to deliver the message flags to the application. Added also
6602 the `flags' arguments to the silc_client_send_channel_message
6603 and silc_client_send_private_message functions. Affected file
6606 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Redefined the Private Message Payload to support private message
6609 keys and to support the new private message flags. Updated
6610 the protocol specs. Flags makes it possible to have for example
6611 CTCP style messages.
6613 * Added new type SilcPrivateMessagePayload and defined an API
6614 for it in the lib/silcclient/silcprivate.[ch].
6616 * Tested private message private keys successfully. Tested the
6617 private message key set, unset and list commands with the new
6620 * Redefined the Channel Message Payload to include the channel
6621 message flags (equal with private message flags) to support
6622 for example CTCP style messages.
6624 * Defined some of the message (for channel and private message)
6625 flags. Updated the protocol specs and added the flags to the
6626 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6628 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Added SilcKeyAgreementStatus type to the key agreement routines
6631 to indicate the current status and error if one occured.
6632 The status types are defined in the lib/silcclient/silcapi.h.
6634 * Added new local command KEY that is used to set and unset private
6635 keys for channels, set and unset private keys for private messages
6636 with remote clients and to send key agreement requests and
6637 negotiate the key agreement protocol with remote client. The
6638 key agreement is supported only to negotiate private message keys,
6639 it currently cannot be used to negotiate private keys for channels,
6640 as it is not convenient for that purpose.
6642 * Fixed a minor pending callback setting bug in the function
6643 silc_client_get_client_by_id_resolve, now the function works.
6644 Affected file lib/silcclient/idlist.c.
6646 * Added function silc_net_get_local_port to get local bound
6647 port by socket. Added to lib/silcutil/silcnet.[ch].
6649 * Added `sockets' and `sockets_count' fields to the SilcClient
6650 object. They hold the sockets of the listenning sockets in
6651 the client. Listenning sockets may be for example the key
6652 agreement server. Affected file lib/silcclient/client.[ch].
6653 Added functions the silc_client_add_socket and the
6654 silc_client_del_socket. They are exported to the application
6657 * Added ~./silc/clientkeys to support other client's public keys.
6659 * Renamed verify_server_key client operation to verify_public_key
6660 and added one argument to indicate the type of the connection
6661 (server, client etc.).
6663 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Added silc_server_connection_auth_request to handle the
6666 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6667 silcd/packet_receive.[ch].
6669 * Added silc_server_send_connection_auth_request into the
6670 silcd/packet_send.c to send the connection auth request packet.
6672 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6675 * Fixed the public key authentication in responder side in the
6676 server. The `auth_data' pointer includes the SilcPublicKey
6677 not the path to the public key. Affected file silcd/protocol.c.
6679 * Implemented the public key authentication in the initiator side
6680 in the server. Affected file silcd/protocol.c.
6682 * Removed the [RedirectClient] config section from the server
6683 configuration. Is not needed and I don't want to implement it.
6685 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Cleaned up the CMODE command in the server. It now works
6688 correctly and supports all the modes defined in the protocol.
6689 Affected file is silcd/command.c.
6691 * Added `hmac_name' field to the SilcChannelEntry in the server
6692 to hold the default HMAC of the channel. It can be set when
6693 creating the channel (with JOIN command). Affected files
6696 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6697 type to indicate the change of the current cipher and hmac
6698 on the channel. Client can safely ignore the <cipher> argument
6699 (if it chooses to do so) since the CHANNEL_KEY packet will
6700 force the channel key change anyway. The <hmac> argument is
6701 important since the client is responsible of setting the new
6702 HMAC and the hmac key into use.
6704 * Fixed the CMODE command in the client library as well.
6706 * Tested CMODE command in router environment successfully.
6708 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Show the version of the remote client (or server) when connecting
6711 to the server. It is logged to the log file. Affected file
6712 is silcd/protocol.c.
6714 * Fixed the KILLED notify handling in the client library. The
6715 client must be removed from all channels when receiving the
6718 Also, do not remove the client entry when giving the KILL
6719 command but when the KILLED notify is received.
6721 * Removed silc_idlist_find_client_by_nickname from the server.
6722 Not needed anymore. Affected files silcd/idlist.[ch].
6724 * Implemented the CHANNEL_CHANGE notify type handling to the
6725 server. Affected file silcd/server.c.
6729 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Added silc_server_send_notify_invite to send the INVITE
6732 notify between routers.
6734 * Implemented the INVITE command correctly to the server.
6736 * Implemented the INVITE notify type handling in the server.
6738 * Implemented the INVITE command to the client library and on the
6741 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added function silc_server_get_client_resolve to find the
6744 client entry by ID from all ID lists and then resolve it
6745 (using WHOIS) if it cannot be found. Affected file is
6748 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Implemented the BAN command to the client library.
6752 * The JOIN command in the server now checks the invite list
6755 * Changed the silc_command_reply_payload_encode_va and the
6756 silc_command_payload_encode_va to support that if argument is
6757 NULL it ignores and checks the next argument. Affected file
6758 lib/silccore/silccommand.c.
6760 * Added silc_server_send_notify_ban to send the BAN notify
6761 type between routers.
6763 * Chaned the silc_notify_payload_encode to support that if
6764 argument is NULL it ignores and checks the next argument.
6765 Affected file lib/silccore/silcnotify.c.
6767 * Tested ban lists in router environment successfully.
6769 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Implemented BAN command to the server, in silcd/command.[ch].
6773 * Removed the BAN and INVITE_LIST modes from the CMODE command
6776 * Added function silc_string_match to regex match two strings.
6777 Affected files lib/silcutil/silcutil.[ch].
6779 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Redefined parts of the SilcChannelEntry in the server to support
6782 the new ban and invite lists.
6784 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Redefined the INVITE command. The same command can be used to
6787 invite individuals to the channel but also to manage the invite
6788 list of the channel (to add to and remove from the invite list).
6789 Updated the protocol specs.
6791 * Added new command SILC_COMMAND_BAN that can be used to manage
6792 the ban list of the channel. Updated the protocol specs.
6794 * Removed the channel modes: the SILC_CMODE_BAN and the
6795 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6796 in the CMODE command. The equivalent features are now available
6797 using INVITE and BAN commands. Updated the protocol specs.
6799 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6800 in the network about change in the current ban list. The notify
6801 type is not used by the client.
6803 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6804 support the invite lists.
6806 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Added new function silc_string_regexify that converts string
6809 including wildcard characters into regex string that can
6810 be used by the GNU regex library. Added into the file
6811 lib/silcutil/silcutil.[ch].
6813 Added silc_string_regex_combine to combine to regex strings
6814 into one so that they can be used as one regex string by
6815 the GNU regex library. Added into the file
6816 lib/silcutil/silcutil.[ch].
6818 Added silc_string_regex_match to match two strings. It returns
6819 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6821 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Imported GNU regex to the soruce tree into lib/contrib.
6824 Fixed some compiler warning from the regex.c.
6826 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Fixed MOTD command in the server to work in router environment.
6830 * Fixed the MOTD command in the client library to support
6831 the server argument in the command.
6833 * Added `nickname_len' argument to the silc_idlist_add_client
6834 in the server, as the `nickname' argument may be binary data
6837 * Added silc_idlist_get_channels to return all channels from
6840 * Implemented LIST command to the server. Affected file is
6843 * Implemented the LIST command to the client library and on the
6846 * Added [<user count>] argument to the LIST command reply.
6847 With private channels the user count is not shown.
6849 * Updated TODO and README.
6851 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * The client entry's data.registered must be TRUE even with
6854 global client entry on global client list. The data.registered
6855 is used to check whether the client is anymore in the network,
6856 for example with WHOWAS command so it must be valid.
6858 * Fixed the WHOWAS command in the server. It now actually works
6859 in router environment. Added function into silcd/command_reply.c
6860 silc_server_command_reply_whowas_save.
6862 * Added silc_idlist_purge function to the silcd/idlist.c
6863 to periodically purge the ID Cache.
6865 * Fixed INFO command in the server. It works now in router
6866 environment. Added <server name> argument to the INFO command
6867 reply. Updated the protocol specs.
6869 * Fixed minor bug in silc_idcache_purge to not purge if the
6870 expire value is zero.
6872 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6873 they were buggy because of the WHOWAS information.
6875 * Fixed local command MSG to handle the async resolving of
6876 the remote client properly. It used to fail the first MSG.
6877 Affected file silc/local_command.c.
6879 * Added `data_len' field to SilcIDCache context.
6881 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Update TODO. Todo in commands in the server.
6885 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6888 used by routers as broadcast packet to inform other routers
6889 about the changed user mode.
6891 Implemented the notify handling in the server. Affected file is
6892 silcd/packet_receive.c. Added the function
6893 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6895 * Added new generic Channel Payload and deprecated the New Channel
6896 Payload. The New Channel Payload is now the generic Channel
6899 * Added new argument `mode' to the silc_server_send_new_channel
6900 as it is required in the Channel Payload now.
6902 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6903 and created a new and real SilChannelPayload to represent the
6904 new generic Channel Payload. Implemented the encode/decode
6905 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6907 * Added silc_server_get_client_channel_list to return the list
6908 of channels the client has joined for WHOIS command reply.
6909 Affected file silcd/server.[ch].
6911 * Implemented the channel list sending in the WHOIS command reply
6912 in server and in the client.
6914 Implemented the channel list displaying on the user interface
6915 as well. Affected file silc/client_ops.c.
6917 * Added silc_channel_payload_parse_list to parse list of Channel
6918 Payloads. It returns SilcDList list of SilcChannelPayloads.
6919 Client for example can use this function to parse the list of
6920 channels it receives in the WHOIS command reply. The caller
6921 must free the list by calling silc_channel_payload_list_free.
6922 Affected files lib/silccore/silcchannel.[ch].
6924 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added one new argument <user mode> to the WHOIS command reply
6927 to return the mode of the user in SILC. Updated the protocol
6930 Implemented it to the server and client.
6932 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Fixed the mode printing on the user interface on joining.
6935 Affected file silc/client_ops.c.
6937 * Implemented the UMODE command and user modes in general to the
6938 client library and to the user interface.
6940 * Implemented the UMODE command to the server.
6942 * The server now sends UNKNOWN_COMMAND error status if client sends
6943 unknown command. Affected file silcd/command.c.
6945 * All server commands now handle the command identifier the right
6946 way when sending the command reply to the client. The client can
6947 use to identify the command replies with the identifier.
6949 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Added silc_server_get_client_route to resolve the route to
6952 the client indicated by the client ID. Affected file is
6955 * Added silc_server_relay_packet as general function to relay
6956 packet to arbitrary destination. This deprecates functions
6957 like _send_private_message_key, _relay_notify etc. Affected
6958 file is silcd/packet_send.[ch].
6960 Removed silc_server_send_key_agreement,
6961 silc_server_send_private_message_key and
6962 silc_server_packet_relay_notify functions from the file
6963 silcd/packet_send.[ch].
6967 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6968 server. Affected file silcd/packet_receive.[ch].
6970 * Implemented the KILL command to the client. Implemented the
6971 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6972 Affected files lib/silcclient/command[_reply].c and
6973 lib/silcclient/client_notify.c. Implemented the KILL notify
6974 printing in the user inteface.
6976 * Fixed a lot silc_parse_nick memory leaks from the client
6977 library in the file lib/silcclient/command.c.
6979 * Changed the silc_server_send_notify_on_channels's `sender'
6980 argument from SilcSocketConnection to SilcClientEntry to
6981 check the sender as entry and not as connection object and not
6982 to send to the client provided as argument. The affected file
6983 is silcd/packet_send.[ch].
6985 * The notify packets that are destined directly to the client used
6986 to not to be processed by the server. Now changed that and the
6987 server processes all notify packets. After relaying the packet
6988 to the client the notify packet is processed in the server.
6990 * The silc_server_free_client_data now checks whether there is
6991 pending outgoing traffic for the client and purges the data to
6992 the network before removing the client entry.
6994 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6997 an client is killed from the SILC Network. Updated the protocol
7000 Added new function silc_server_send_notify_killed to the
7001 silcd/packet_send.[ch].
7003 * Added function silc_server_packet_relay_notify to relay notify
7004 packets that are destined directly to a client. In this case
7005 the server does not process the notify packets but merely relays
7006 it to the client. Affected file silcd/packet_send.[ch].
7008 Added also silc_server_packet_process_relay_notify to check
7009 whereto relay the notify. Affected file is
7010 silcd/packet_receive.[ch].
7012 * Implemented the KILL command to the server.
7016 * Added the backup schema desgined last fall to the protocol
7017 specs for everyone to see. The specification is in the
7018 *-spec-xx.txt draft and the packet type definitions for the
7019 backup routers is in *-pp-xx.txt draft. Thusly, added also
7020 new packet type SILC_PACKET_CELL_ROUTERS.
7022 * A big security problem in the implementation discovered. The
7023 signoff of an client did not cause new channel key generation
7024 which it of course should've done. The channel keys must be
7025 always re-generated when client leaves (or signoffs) the channel.
7026 The silc_server_remove_from_channels funtion now handles
7027 the channel key re-generation.
7029 * Added `sender' argument to the silc_server_send_notify_on_channels
7030 to not to send the client provided as argument. Affected file
7031 silcd/packet_send.[ch].
7033 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Implemented OPER and SILCOPER commands into the server and
7038 * Added silc_auth_verify and silc_auth_verify_data to verify
7039 the authentication directly from the authentication payload.
7040 It supports verifying both passphrase and public key based
7041 authentication. Affected file lib/silccore/silcauth.[ch].
7043 * Added `hash' field to the SilcIDListData structure. It is the
7044 hash negotiated in the SKE protocol. Affected file is
7047 * Slight redesigning of the SilcAuthPayload handling routines.
7048 Do not send SilcPKCS but SilcPublicKey as argument.
7050 * Implemented the public key authentication support to the
7051 serverconfig. The public key is loaded from the provided path
7052 and saved as authentication data to void * pointer. Thus,
7053 changed the unsigned char *auth_data to void *auth_data;
7055 * Fixed SHUTDOWN command to send the reply before the server
7056 is shutdown. :) Affected file silcd/command.c.
7058 * Fixed fatal bug in CONNECT command. The hostname was invalid
7059 memory and server crashed. Affected file silcd/command.c.
7061 * Fixed fatal bug in CLOSE command. The server_entry became
7062 invalid but was referenced later in the command. Affected file
7065 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Fixed fatal bug in failure packet handling. Server ignored
7068 the failure and thus crashed when it came.
7072 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7075 that the command may be executed only once in (about) 2 seconds.
7076 The old SILC_CF_LAG flag is same but allows command bursts up
7077 to five before limiting.
7079 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7080 server code. Various commands now includes the CF_LAG_STRICT
7081 flag to disallow any kind of miss-use of the command.
7083 * Fixed the silc_buffer_unformat to not to allocate any data
7084 if the length of the data is zero. It used to allocate the
7085 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7087 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Changed the format of AdminConnection configuration section
7090 in the server. Added username of the admin to the format.
7091 Affected files silcd/serverconfig.[ch].
7093 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7094 to return admin configuration data by host, username and/or
7097 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Implemented WHOWAS command to the server. Added the functions:
7101 silc_server_command_whowas_parse,
7102 silc_server_command_whowas_send_reply,
7103 silc_server_command_whowas_from_client and
7104 silc_server_command_whowas_from_server
7106 * Added <Client ID> argument to the WHOWAS command reply. Updated
7107 the protocol specs accordingly.
7109 * Implemented WHOWAS command and command_reply to the client
7112 Implemented the WHOWAS printing on the user interface.
7114 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Added new argument to the WHOWAS command reply, the real name.
7117 It is an optional argument. Updated the protocol specs.
7119 * Added SilcIDCacheDestructor callback that is registered when
7120 the SilcIDCache is allocated. The callback is called when
7121 an cache entry in the ID Cache expires, or is purged from the
7122 cache. Added into lib/silccore/idcache.[ch].
7124 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7125 to destruct the client entries when the cache entry expires.
7126 Other ID Cache's in server and in the client library ignores
7129 * If the ID Cache entry's `expire' field is zero then the entry
7130 never expires. Added boolean `expire' argument to the
7131 silc_idcache_add function in the lib/silccore/idcache.[ch].
7132 If it is TRUE the default expiry value is used.
7134 * Added silc_server_free_client_data_timeout that is registered
7135 when client disconnects. By default for 5 minutes we preserve
7136 the client entry for history - for WHOWAS command.
7138 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Added support to the server to enforce that commands are not
7141 executed more than once in 2 seconds. If server receives
7142 commands from client more frequently, timeout is registered
7143 to process the commands. Affected file silcd/command.c.
7144 Added new function silc_server_command_process_timeout.
7146 * Changed NICK_NOTIFY handling in client library to check that
7147 if the client's nickname was changed, so there is no need to
7148 resolve anything from the server.
7150 * Removed error printing from the WHOIS and IDENTIFY commands.
7151 If error occurs then it is ignored silently in the client library.
7152 The application, however, may map the received error to
7153 human readable error string. The application currently maps
7154 the NO_SUCH_NICKNAME error to string.
7156 * Made the command status message public to the application. Moved
7157 them from lib/silcclient/command_reply.c to
7158 lib/silcclient/command_reply.h. The application can map the
7159 received command status to the string with the
7160 silc_client_command_status_message function.
7162 * Added check to the server to check that client's ID is same
7163 as the Source ID in the packet the client sent. They must
7166 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Added dist-bzip hook to the Makefile.am to make bzip2
7169 compressed distributions.
7171 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Server now enforces the maximum length for the nickname and
7174 the channel as protocol specification dictates. 128 bytes for
7175 nickname and 256 bytes for channel name.
7177 * Moved the WHOIS printing to the application. The client libary
7178 does not print out the WHOIS information anymore, the application
7179 must do it. Renamed silc_client_command_reply_whois_print to
7180 the silc_client_command_reply_whois_save.
7182 The client's idle time is also sent to the application now, and
7183 the idle is shown on screen.
7185 * Added silc_client_command_reply_identify_save to save the
7186 received IDENTIFY entries.
7188 * Do not check for channel private keys in message sending and
7189 reception if the channel does not have the PRIVKEY mode set.
7190 Affected file lib/silclient/client_channel.c.
7192 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7195 just surfaced after chaning the JOIN procedure.
7197 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added silc_client_get_clients_by_list to get client entries
7200 from Client ID list, that is returned for example by JOIN
7201 and USERS command replies. The application should use this
7202 function for example when JOIN command reply is received to
7203 resolve the clients already on the channel (library does not
7204 do that anymore as USERS command reply is not used in the JOIN
7205 procedure anymore). Affected files lib/silcclient/silcapi.h and
7206 lib/silcclient/idlist.c.
7208 * JOIN command reply and USERS command reply returns now SilcBuffer
7209 pointers instead of unsigned char pointers when returning
7210 the client list and mode list.
7212 * Added <Client ID> argument to the JOIN command reply, mainly
7213 for the server to identify for which client the command was
7214 originally sent. Updated protocol specs accordingly.
7216 * Added SilcDlist private_key pointer to the SilcChannelEntry
7217 in the client to support the channel private keys. Affected
7218 file is lib/silcclient/idlist.h.
7220 * Added SilcChannelPrivateKey argument to the function
7221 silc_client_send_channel_message so that application can choose
7222 to use specific private ke if it wants to. If it is not provided,
7223 the normal channel key is used, unless private keys are set.
7224 In this case the first (key that was added first) is used
7225 as the encryption key.
7227 * Implemented the support for channel private key handling.
7228 Implemented the following functions:
7230 silc_client_add_channel_private_key,
7231 silc_client_del_channel_private_keys,
7232 silc_client_del_channel_private_key,
7233 silc_client_list_channel_private_keys and
7234 silc_client_free_channel_private_keys
7236 Affected file lib/silcclient/client_channel.c.
7238 * Added the support for the private keys in the channel message
7239 sending and encryption and in the message reception and
7240 decryption. Affected funtions are
7241 silc_client_send_channel_message and silc_client_channel_message.
7243 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Added SKE's key verify callback to the client library's
7246 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7248 * Removed the statement that server (or router) must send USERS
7249 command reply when joining to the channel so that the client
7250 knows who are on the channel. Instead, the client list and
7251 client's mode list is now sent in the JOIN command reply to the
7252 client who joined channel. This is better solution.
7254 * Added function silc_server_get_users_on_channel and function
7255 silc_server_save_users_on_channel to the silcd/server.[ch].
7257 * Removed function silc_server_command_send_users from the
7260 * Do not show topic on the client library anymore. The topic is
7261 sent in the command reply notify to the application and the
7262 application must show the topic now.
7264 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added client searching by nickname hash into the IDENTIFY and
7267 WHOIS commands in the server as they were clearly missing from
7268 them. Affected file is silcd/command.c.
7270 * Fixed a bug in private message receiving in the client library.
7271 The remote ID was freed and it wasn't supposed, now it is
7274 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Minor fix to the channel payload; allocate the data area, as it
7277 needs to be of specific length.
7279 * If the key agreement port is zero then the operating
7280 system will define the bound port. Affected files are
7281 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7283 * Added new function silc_channel_payload_decrypt into the file
7284 lib/silccore/silcchannel.[ch].
7286 * Moved the channel message etc, check from silc_packet_decrypt
7287 to applications. The library calls now a generic
7288 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7289 when the packet is either normal or special. This was done to
7290 allow more wide range of checking that was not allowed when
7291 the code was in library. Now applications can do virtually any
7292 checks to the packet and return to the library the decision how
7293 the packet should be processed. Affected files are
7294 lib/silccore/silcpacket.[ch].
7296 Added silc_server_packet_decrypt_check to the server and
7297 silc_client_packet_decrypt_check to the client library.
7299 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7300 to send with specified source and destination information.
7302 * Channel message delivery between routers was broken after the
7303 channel key distribution was fixed earlier. The channel key
7304 was used be to distributed to other routers as well which is not
7305 allowed by the protocol. Now this is fixed and channel keys
7306 really are cell specific and the channel message delivery between
7307 routers comply with the protocol specification.
7309 * Fixed various commands in server to check also the global list
7310 for the channel entry and not just the local list. The affected
7311 file silcd/command.c.
7313 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Added assert()s to buffer formatting and unformatting routines
7316 to assert (if --enable-debug) when error occurs. Affected
7317 file: lib/silcutil/silcbuffmt.c.
7319 * Changed to auto-reconnect to check whether the remote host is
7320 router and register the re-connect timeout if it is. It used
7321 to check that whether we are normal server, but router must do
7322 auto-reconnect with another router as well. Affected file
7325 * Removed the [<key len>] option from CMODE command as the cipher
7326 name decides the key length, nowadays. See the defined ciphers
7327 from the protocol specification.
7329 * Added [<hmac>] option to the CMODE command to define the HMAC
7330 for the channel. Added SILC_CMODE_HMAC channel mode.
7332 * Added [<hmac>] option for the JOIN command so that user can
7333 select which HMAC is used to compute the MACs of the channel
7336 * Added Hmac field to the Channel Message Payload. The integrity
7337 of plaintext channel messages are now protected by computing
7338 MAC of the message and attaching the MAC to the payload. The
7339 MAC is encrypted. Now, it is clear that this causes some
7340 overhead to the size of the packet but rationale for this is that
7341 now the receiver can verify whether the channel message decrypted
7342 correctly and also when private keys are set for the channel the
7343 receiver can decrypt the packet with several keys and check from
7344 the MAC which key decrypted the message correctly.
7346 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7347 lib/silccrypt/silccipher.[ch].
7349 * Added silc_hash_len to return the digest length into the
7350 lib/silcrypt/silchash.[ch].
7352 * Rewrote parts of Silc Channel Payload interface in the
7353 lib/silccore/silcchannel.[ch]. The encode function now also
7354 encrypts the packet and parse function decrypts it.
7356 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * Fixed a minor formatting bug in the SKE's key material processing.
7359 It actually might have processed the keys wrong way resulting
7362 * Redefined the mandatory HMAC algorithms and added new algorithms.
7363 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7364 and hmac-md5 truncated to 96 bits. The mandatory is now
7365 hmac-sha1-96. Rest are optional (including the one that used
7366 to be mandatory). Rationale for this is that the truncated HMAC
7367 length is sufficient from security point of view and can actually
7368 make the attack against the HMAC harder. Also, the truncated
7369 HMAC causes less overhead to the packets. See the RFC2104 for
7372 * Added new [hmac] configuration section. The SKE used to use
7373 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7374 is of course wrong. The official names that must be proposed in
7375 the SKE are the ones defined in the protocol specification
7376 (hmac-sha1-96 for example). The user can configure any hmac
7377 using any hash function configured in the [hash] section. At
7378 least, the mandatory must be configured.
7380 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7382 * Added HMAC list to the SKE proposal list. It has now both
7383 hash algorithm list and HMAC list. This makes the protocol
7384 incompatible with previous versions. The SKE now seems to work
7385 the way it is supposed to work, for the first time actually.
7387 * Defined plain Hash algorithms to the protocol specification.
7390 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Implemented support for key agreement packets into the server.
7393 Added functions silc_server_key_agreement and
7394 silc_server_send_key_agreement. Other than these functions,
7395 server has nothing to do with this packet.
7397 * Added support for private message key packets into the server.
7398 Added functions silc_server_private_message_key and
7399 silc_server_send_private_message_key.
7403 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7404 called in the protocol's final callback instead in the END
7405 protocol state. This makes a little more sense and in the same
7406 time in client we can use the same protocol routines for normal
7407 key exchange and to key agreement packet handling as well.
7409 * Added to both client's and server's KE protocol context the
7410 SilcSKEKeyMaterial pointer to save the key material. We will
7411 bring the key material to the protocol's final callback by doing
7412 this. The final callback must free the key material.
7414 * Added SKE's packet_send callback into client's KE protocol
7415 context so that the caller can choose what packet sending function
7416 is used. This way we can use different packet sending when
7417 doing normal SKE when doing key agreement packet handling (in
7418 the key agreement packet handling we do not want to encrypt
7421 * Implemented the responder side of the key agreement routines
7422 in the client. The client can now bind to specified port and
7423 accept incoming key negotiation. The key material is passed
7424 to the application after the protocol is over.
7426 * Implemented the processing of incoming Key Agreement packet
7427 in the client. Added function silc_client_key_agreement to
7430 * Implemented the intiator side of the key agreement routines
7431 in the client. The client can now initiate key agreement with
7432 another remote client. The key material is passed to the
7433 application after the protocol is over.
7435 * Created client_keyagr.c to include all the key agreement
7438 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7439 SILC_TASK_CALLBACK except that it is not static.
7441 * Created client_notify.c and moved the Notify packet handling
7442 from the client.[ch] into that file.
7444 * Created client_prvmsg.c and moved all private message and
7445 private message key routines from the client.[ch] into that file.
7447 * Create client_channel.c and moved all channel message and
7448 channel private key routines from the client.[ch] into that file.
7450 * Changed silc_client_get_client_by_id_resolve to resolve with
7451 WHOIS command instead of IDENTIFY command, in the file
7452 lib/silclient/idlist.c.
7454 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7456 * Implemented the SKE's responder side to the Client library.
7458 * When FAILURE is received to the protocol do not trust it
7459 blindly. Register a timeout to wait whether the remote closes
7460 the connection as it should do it, only after that process the
7461 actual failure. This was changed to both client and server.
7463 * Added client_internal.h to include some of the structures
7464 there instead of client.h in lib/silcclient/.
7466 * Added function silc_task_unregister_by_callback to unregister
7467 timeouts by the callback function.
7469 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Some "Incomplete WHOIS info" errors has been appearing on the
7472 log files. Took away the entry->userinfo check from WHOIS
7473 reply sending. The entry->userinfo is now " " if client did not
7474 provide one. I thought this was fixed earlier but something
7475 is wrong still. Let's see if the error still appears.
7477 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Fixed a minor bug in the login when the channel key is
7480 re-generated in the server. It used to generate the key in
7481 wrong order and thus caused problems in the channel traffic.
7483 * Fixed a minor bug in channel key distsribution after
7484 KICK command. The key was not sent to the router even though
7487 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Added silc_ske_process_key_material_data as generic routine
7490 to process any key material as the SILC protocol dictates. The
7491 function is used by the actual SKE library but can be used by
7492 applications as well. This relates to the private message keys
7493 and the channel private keys since they must be processed the
7494 same way the normal SILC session keys. The protocol dictates
7495 this. Affected files: lib/silcske/silcske.[ch].
7497 Added also silc_ske_free_key_material to free the
7498 SilcSKEKeyMaterial structure.
7500 * Defined silc_cipher_set_key function to set the key for
7501 cipher without using the object's method function. The affected
7502 files: lib/silccrypt/silccipher.[ch].
7504 * Implemented silc silc_client_add_private_message_key,
7505 silc_client_add_private_message_key_ske,
7506 silc_client_del_private_message_key,
7507 silc_client_list_private_message_keys and
7508 silc_client_free_private_message_keys functions in the
7511 Added functions silc_client_send_private_message_key to send
7512 the Private Message Key payload and silc_client_private_message_key
7513 to handle incoming Private Message Key payload.
7515 * Added Cipher field to the Private Message Key payload to set
7516 the cipher to be used. If ignored, the default cipher defined
7517 in the SILC protocol (aes-256-cbc) is used.
7519 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Removed lib/silcclient/ops.h file.
7523 Redefined parts of the SILC Client Library API. Created new
7524 file silcapi.h that deprecates the ops.h file and defines the
7525 published Client Library API. Defined also private message key
7526 API and channel private key API into the file.
7528 This is the file that the application must include from the
7529 SILC Client Library. Other files need not be included by
7530 the application anymore.
7532 * Added new key_agreement client operation callback and also
7533 defined the Key Agreement library API for the application.
7535 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7538 is used by clients to request key negotiation between another
7539 client in the SILC network. If the negotiation is started it
7540 is performed using the SKE protocol. The result of the
7541 negotiation, the secret key material, can be used for example
7542 as private message key.
7544 Implemented the Key Agreement payload into the files
7545 lib/silccore/silauth.[ch].
7547 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Redefined ciphers for the SILC protocol. Added some new ciphers
7550 and defined the key lengths for the algorithms. Changed the
7551 code accordingly. The default key length is now 256 bits.
7553 * Fixed SKE key distribution function silc_ske_process_key_material
7554 when the key length is more than 128 bits. The default key
7555 length in SILC is now 256 bits.
7557 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7558 to indicate unsupported algorithm.
7560 * Renamed rijndael.c to aes.c and all functions as well.
7562 * Fixed a long standing channel key setting bug in client library.
7563 Weird that it has never surfaced before.
7565 * Fixed bug in channel deletion. If the entire channel is removed
7566 then it must also delete the references of the channel entry
7567 from the client's channel list as the client's channel entry and
7568 the channel's client entry share same memory.
7570 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Implemented CONNECT and SHUTDOWN commands in the client.
7574 * Implemented CLOSE command to the client.
7576 * Added the function silc_idlist_find_server_by_name into the
7577 files silcd/idlist.[ch].
7579 Added the function silc_idlist_find_server_by_conn into the
7580 files silcd/idlist.[ch].
7582 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * DIE command was renamed to SHUTDOWN. Updated the both code
7587 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7588 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7590 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7593 * Added function silc_server_create_connection function to create
7594 connection to remote router. My server implementation actually
7595 does not allow router to connect to normal server (it expects
7596 that normal server always initiates the connection to the router)
7597 so the CONNECT command is only good for connecting to another
7600 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7603 or some other client was kicked from the channel.
7605 Implemented the handling of the notify type to both client
7608 Implemented silc_server_send_notify_kicked to send the KICKED
7609 notify. It is used to send it to the server's primary router.
7611 * Implemented the KICK command into server and client.
7613 * Added `query' argument to the silc_idlist_get_client function
7614 to indicate whether to query the client from server or not if
7617 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7618 to indicate that the client is not channel founder.
7622 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Removed the rng context from SilcPacketContext structure and
7625 changed that the packet routine uses the Global RNG API.
7627 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7629 * Added support for quit message that client can "leave" on the
7630 channel when it quits the SILC. It is ditributed inside the
7631 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7633 Added silc_server_free_client_data that will take the
7634 signoff message as argument.
7636 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7638 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Updated parts of the protocol specification to keep it up
7643 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7646 payloads in one packet.
7648 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7649 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7650 use now the new List flag.
7652 * Also deprecated the following packet types: REPLACE_ID,
7653 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7655 * Added list support for Notify packet in server.
7657 * Added silc_server_send_notify_channel_change to send the
7658 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7659 the silc_server_send_replace_id.
7661 * Added silc_server_send_notify_nick_change to send the
7662 NICK_CHANGE notify type. Deprecates the function
7663 silc_server_send_replace_id.
7665 * Added silc_server_send_notify_join to send the JOIN notify type.
7666 Deprecates the function silc_server_send_new_channel_user.
7668 * Added silc_server_send_notify_leave to send LEAVE notify type.
7669 Deprecates the function silc_server_send_remove_channel_user.
7671 * Added silc_server_send_notify_cmode and
7672 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7673 types. Deprecates the silc_server_send_set_mode function.
7675 * Added SERVER_SIGNOFF notify type to indicate that server has
7676 quit. This means that all clients on the channel from that
7677 server will drop. This can be also used when netsplit happens.
7679 Deprecated REMOVE_ID packet type since it is not needed anymore
7682 Added silc_server_send_notify_server_signoff to send the
7683 SERVER_SIGNOFF notify type. Deprecates the function
7684 silc_server_send_remove_id.
7686 Added also silc_server_send_notify_signoff to send the
7687 SIGNOFF notify type.
7689 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7690 SILC protocol from this day on. Changed the protocol
7691 specification as well.
7693 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7694 notify type. It is used between routers to notify about
7695 topic changes on a channel.
7697 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7700 * Partly updated the protocol specification to comply with the
7701 changes now made. It is still though a bit outdated.
7703 * The JOIN notify type now takes one extra argument <Channel ID>.
7704 The packet used to be destined to the channel but now the
7705 JOIN type may be sent as list thus it is impossible to
7706 destine it to any specific channel. By adding this argument
7707 it is again possible.
7709 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Added CREDITS file. The CHANGES and CREDITS file will appear
7712 in the distribution as well.
7714 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7717 types in the server's silcd/packet_receive.c.
7719 * Implemented CMODE and CUMODE to work in router environment.
7721 * Fixed minor encoding and decoding buglet from the
7722 lib/silccore/silcmode.c.
7724 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7727 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7729 * Changed all SilcConfigServer* and silc_config_server* to
7730 SilcServerConfig* and silc_server_config*, respectively.
7733 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Associated the ID (client or server ID) to the Authentication
7736 Payload to avoid any possibility of forging. Updated the
7737 protocol specification and the code accordingly.
7739 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7741 * The RSA key length is now save to the RsaKey context in the
7742 key generation process in lib/silccrypt/rsa.c. The key length
7743 is now used to figure out the maximum size of the block allowed
7744 to be encrypted/signed.
7746 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7747 is equivalent to the silc_mp_mp2bin but does not allocate any
7750 * Changed silc_mp_mp2bin API to take length argument. If it is
7751 non-zero then the buffer is allocated that large. If zero, then
7752 the size is approximated using silc_mp_sizeinbase, which however
7755 * Created Global RNG API which is global RNG that application can
7756 initialize. After initializing, any routine anywhere in the
7757 code (including library) can use RNG without allocating a new
7758 RNG object. This was done to allow this sort of use of the
7759 RNG in code that has no chance to allocate RNG object. All
7760 applications currently allocate this and many routines in the
7761 library use this. Affected file lib/silccrypt/silcrng.[ch].
7763 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7764 it to use the Global RNG API.
7766 * Defined Authentication Payload into protocol specification that
7767 is used during SILC session to authenticate entities. It is
7768 used for example by client to authenticate itself to the server
7769 to obtain server operator privileges.
7771 Implemented this payload into the lib/silccore/silcauth.[ch].
7772 Implemented also routines for public key based authentication
7773 as the new protocol specification dictates.
7775 Moved definitions of different authentication methods from
7776 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7778 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7779 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7780 silc_pkcs_verify_with_hash functions into the file
7781 lib/silccrypt/silcpkcs.[ch].
7783 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * The client entry's userinfo pointer must be always valid.
7786 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7787 will fail since it requires the userinfo. Now, the userinfo
7788 is allocated as "" if actual userinfo does not exist. Actually,
7789 it must exist and it is totally Ok to drop client connections
7790 that does not announce the userinfo. However, we will make
7791 this workaround for now.
7793 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7794 to return the remote port by socket.
7796 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7798 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7799 SILC_SERVER_PENDING_EXEC and added an new macro
7800 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7801 data or when error occurs while processing the pending command.
7803 Added new argument `destructor' into silc_server_command_pending
7804 and to the SilcServerCommandPending object. This destructor is
7805 now called after calling the pending callback or if error occurs
7806 immediately. If error occurs the actual pending callback won't
7807 be called at all - only the destructor. The destructor may be
7808 NULL if destructor is not needed.
7810 All this applies for client library code as well. Similar
7811 changes were made there as well for the pending commands.
7813 In the client, the application must now allocate the
7814 SilcClientCommandContext with the silc_client_command_alloc
7817 * Added reference counter to the SilcServerCommandContext. Added
7818 function silc_server_command_alloc and silc_server_command_dup
7821 Same type of functions added to the client library for the same
7824 * Removed the cmd_ident from IDListData away since it is now
7825 global for all connections. It is the command identifier used
7826 in command sending and with pending commands. The affected file
7829 * Added reference counter to the SilcSocketConnection objecet to
7830 indicate the usage count of the object. The object won't be
7831 freed untill the reference counter hits zero. Currently only
7832 server uses this, and client ignores it. The client must be
7833 set to use this too later. The affected files are
7834 lib/silccore/silcsockconn.[ch]. Added also the function
7835 silc_socket_dup to increase the reference counter.
7837 This was mainly added because it is possible that the socket
7838 is removed underneath of pending command or other async
7839 operation. Now it won't be free'd and proper DISCONNECTING
7840 flags, etc. can be set to avoid sending data to connection that
7841 is not valid anymore.
7843 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7844 the connection. After that it sets SILC_SET_DISCONNECTED.
7845 It is, however, possible that the socket data is not still freed.
7846 The silc_server_packet_process now checks that data is not
7847 read or written to connection that is DISCONNECTED. The socket
7848 get's freed when the reference counter hits zero.
7850 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * Changed the client operation API: channel_message operation's
7853 `sender' is now the client entry of the sender, not the nickname
7854 and the `channel' is the channel entry, not the channel name.
7856 In the private_message operation the `sender' is now also the
7857 client entry of the sender not the nickname.
7859 Affected file is lib/silcclient/ops.h and all applications
7860 using the client operations.
7862 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7864 * Moved the calling of ops->connect() from connect_to_server_final
7865 into receive_new_id functin since that is the point when the
7866 client is actually allowed to send traffic to network. The
7867 affected file is lib/silcclient/client.c.
7869 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7871 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7872 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7873 (if needs broadcasting) instead of broadcasting the packets one
7874 by one which would make a burst in the network traffic.
7876 * Added `broadcast' argument to the functions in silcd/server.[ch]
7877 silc_server_create_new_channel[_with_id] to indicate whether
7878 to send New Channel packet to primary router.
7880 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7882 * Added new function into the silcd/server.[ch] files:
7883 silc_server_create_new_channel_with_id to create new channel with
7884 already existing Channel ID.
7886 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7887 lib/silccore/silcpacket.h. This packet is used t send list of
7888 Set Mode payloads inside one packet. Server uses this to set
7889 the modes for the channels and clients on those channels, that it
7890 announced to the router when it connected to it. The protocol
7891 specification has been updated accordingly.
7893 * The silc_server_new_channel did not handle the packet coming
7894 from normal server as it normally does not send that. However,
7895 when it announces its channels it does send it. Implemented
7896 the support for that.
7898 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7899 into the file lib/silccore/id.h.
7901 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7903 * Fixed memory leaks in the functions silc_idlist_del_client,
7904 silc_idlist_del_channel and silc_idlist_del_server in the file
7905 silcd/idlist.c. All of those leaked like a sieve.
7907 * Fixed some small memory leaks in the client's function
7908 silc_client_notify_by_server.
7910 * Added functions into silcd/server.c: silc_server_announce_clients,
7911 silc_server_announce_channels and silc_server_announce_server.
7912 These functions are used by normal and router server to announce
7913 to its primary router about clients, channels and servers (when
7914 router) that we own. This is done after we've connected to the
7917 These functions effectively implements the following packet types:
7918 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7919 and SILC_PACKET_NEW_ID_LIST.
7921 * Added new functions into the silcd/packet_receive.[ch]:
7922 silc_server_new_id_list, silc_server_new_channel_list and
7923 silc_server_new_channel_user_list to handle the incoming
7924 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7926 * Added support of changing Channel ID in the function
7927 silc_server_replace_id. If the server that announces a channel
7928 to the router already exists in the router (with same name but
7929 with different Channel ID), router is responsible to send
7930 Replace ID packet to the server and force the server to change
7931 the Channel ID to the one router has.
7933 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7934 client that the Channel ID has been changed by the router. The
7935 normal server sends this to the client. Client must start using
7936 the new Channel ID as the channel's ID.
7938 Implemented handling of this new type into lib/silcclient/client.c
7939 into the function silc_client_notify_by_server.
7941 * Added new function silc_idlist_replace_channel_id into the files
7942 silcd/idlist.[ch] to replace the Channel ID.
7944 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7946 * Call silc_server_command_identify_check always when processing
7947 the IDENTIFY command in silcd/command.c
7949 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7951 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7952 send keepalive packets. The packet can be sent by clients,
7953 servers and routers.
7955 Added function silc_socket_set_heartbeat into the file
7956 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7957 If not set, the heartbeat is not performed. The actual
7958 heartbeat is implemented in the low level socket connection
7959 library. However, application is responsible of actually
7962 Added silc_server_send_heartbeat to send the actual heartbeat
7963 packet into silcd/packet_send.[ch]. Server now performs
7964 keepalive with all connections.
7966 * Added silc_task_get_first function into lib/silcutil/silctask.c
7967 to return the timeout task with shortest timeout. There was a bug
7968 in task unregistration that caused problems. TODO has been
7969 updated to include that task system must be rewritten.
7971 * The client library will now resolve the client information when
7972 receiving JOIN notify from server for client that we know but
7973 have incomplete information.
7975 * Rewrote parts of silc_server_remove_from_channels and
7976 silc_server_remove_from_one_channel as they did not remove the
7977 channel in some circumstances even though they should've.
7979 * Encryption problem encountered in server:
7981 The LEAVE command used to send the Channel Key packet to the
7982 router immediately after generating it. However, the code
7983 had earlier sent Remove Channel user packet but not immediately,
7984 ie. it was put to queue. The order of packets in the router
7985 was that Channel Key packet was first and Remove Channel User
7986 packet was second, even though they were encrypted in the
7987 reverse order. For this reason, MAC check failed. Now, this
7988 is fixed by not sending the Channel Key packet immediately but
7989 putting it to queue. However, this is more fundamental problem:
7990 packets that are in queue should actually not be encrypted
7991 because packets that are sent immediately gets encrypted
7992 actually with wrong IV (and thus MAC check fails). So, packets
7993 that are in queue should be encrypted when they are sent to
7994 the wire and not when they put to the queue.
7996 However, the problem is that the current system has not been
7997 designed to work that way. Instead, the packet is encrypted
7998 as soon as possible and left to the queue. The queue is then
7999 just purged into wire. There won't be any fixes for this
8000 any time soon. So, the current semantic for packet sending
8003 o If you send packet to remote host and do not force the send
8004 (the packet will be in queue) then all subsequent packets to the
8005 same remote host must also be put to the queue. Only after the
8006 queue has been purged is it safe again to force the packet
8009 o If you send all packets immediately then it safe to send
8010 any of subsequent packets through the queue, however, after
8011 the first packet is put to queue then any subsequent packets
8012 must also be put to the queue.
8014 Follow these rules and everything works fine.
8016 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Added new function silc_server_remove_clients_by_server to
8019 remove all client entries from ID list when the server connection
8020 is lost. In this case it is also important to invalidate all
8021 client entires as they hold the invalid server entry. This
8022 fixes fatal bug when server has lost connection and will reconnect
8025 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8027 * Made some sanity checks to silc_server_daemonise like to check
8028 whether the requested user and group actually exists.
8030 * Added sanity check to SKE's silc_ske_responder_finish to check
8031 that the public and private key actually is valid.
8033 * Invalidate the client's nickname when receiving Replace ID
8034 packet and the Client ID is being replaced. This means that the
8035 server will query the nickname if someone needs it (client)
8038 * Sort the ID Cache in client library when the ID Cache data
8039 has changed (needs sorting).
8041 * Do not allow for SILC client to create several connections to
8042 several servers. The client does not support windows right now
8043 and generating multiple connections causes weird behaviour.
8045 Irssi-silc client does support windows and can handle several
8046 connections without problems, see: www.irssi.org and SILC plugin.
8048 * Fixed some places where client was added to the IDList. The
8049 rule of thumb is following (in order to get everything right):
8050 If the client is directly connected local client then the
8051 `connection' argument must be set and `router' argument must be
8052 NULL to silc_idlist_add_client function. If the client is not
8053 directly connected client then the `router' argument must
8054 bet set and the `connection' argument must be NULL to the
8055 silc_idlist_add_client function.
8057 * The funtion silc_server_packet_send_local_channel actually did
8058 not check whether the client was locally connected or not. It
8059 does that now. Fixed a bug related to LEAVE command.
8061 * Fixed Remove Channel User payload parsing bug in server's
8062 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8064 * The server's silc_server_save_channel_key now checks also the
8065 global ID list for the channel as it might not be in the local
8066 list. Fixed a bug related to LEAVE command.
8068 * Is this the end of the [<unknown>] buglet that has been lurking
8069 around for a long time? A little for loop fix in server's
8070 silc_server_command_whois_parse that is used by both IDENTIFY
8071 and WHOIS command. At least, this was a clear bug and a cause
8072 of one type of [<unknown>] buglet.
8074 * WHOIS and IDENTIFY commands call the function
8075 silc_server_command_[whois/identify]_check function even if
8076 we are not router server.
8078 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Added --with-gmp configuration option. If set the GMP
8081 is always compiled in the SILC source tree. If not set then
8082 it is checked whether the system has the GMP3 installed. If
8083 it has then the GMP won't be compiled (the system's headers
8084 and library is used), if it doesn't have it then the GMP is
8085 compiled in the SILC source tree.
8087 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * Changed RSA private exponent generation to what PKCS #1
8090 suggests. We try to find the smallest possible d by doing
8091 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8092 not security fix but optimization.
8094 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Added new config entry [Identity] to fork the server and run
8097 it as specific user and group. A patch from Bostik.
8099 * Imported Dotconf configuration library into lib/dotconf.
8100 This will be used to create the SILC configuration files later.
8101 It will appear in the distsribution after this commit.
8103 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8105 * A big code auditing weekend happening. Auditing code for
8106 obvious mistakes, bugs and errors. Also, removing any code
8109 Removed files for being obsolete:
8111 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8112 inline in the file lib/silcutil/silcbuffer.h)
8114 o lib/silcutil/silcbufutil.c (the header has inline versions)
8116 Changed code to fix possible error conditions:
8118 o The buffer formatting routines now check that the destination
8119 buffer really has enough space to add the data. This applies for
8120 both buffer formatting and unformatting
8121 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8122 unformatting was changed to accomodate following rules:
8123 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8124 sent to the function while XXX_*STRING will not allocate or copy
8125 the data into the buffer. Instead it sets the pointer from the
8126 buffer into the pointer sent as argument (XXX_*STRING used to
8127 require that the pointer must be allocated already). This change
8128 makes this whole thing a bit more consistent and more optimized
8129 (note that the data returned in the unformatting with XXX_*STRING
8130 must not be freed now). The routines return now -1 on error.
8132 o Tried to find all code that use buffer_format and buffer_unformat
8133 and added return value checking to prevent formatting and
8134 especially unformatting errors and possible subsequent fatal
8137 o Changed ske->x and ske->KEY to mallocated pointers in
8138 lib/silcske/silcske.h. Fixed possible data and memory leak.
8140 o Added return value checking to all *_parse* functions. Fixed
8141 many memory leaks as well.
8143 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8144 so that buffer overflows would not happen. All code now also
8145 checks the return value as it can fail.
8147 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8149 * Added reconnection support to server if the normal server looses
8150 its connection to the router (for example if router is rebooted).
8151 The server performs normal reconnection strategy implemented
8152 to the server. Affected file silcd/server.c.
8154 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Added new packet type SILC_PACKET_SET_MODE that is used to
8157 distribute the information about changed modes (for clients,
8158 channels and clients channel modes) to all routers in the
8159 network. Updated the protocol specification accordingly.
8161 Added functions into silcd/packet_send.c and
8162 silcd/packet_receive.c: silc_server_send_set_mode,
8163 silc_server_set_mode.
8165 Added new files silcmode.[ch] into lib/silccore that implements
8166 the encoding and decoding of Set Mode Payload. Added new type
8167 SilcSetModePayload. Moved the definitions of different modes
8168 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8170 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Oops, a little mistake in server's connection authentication
8173 protocol. The protocol is not ended with FAILURE but with
8174 SUCCESS if the authentication is Ok. :) Affected file is
8177 * Implemented NICK_CHANGE notify handling in server in the file
8178 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8179 the local clients on the channel. After the changing nickname
8180 in router environment snhould work and the [<unknown>] nickname
8181 should appear no more.
8183 The silc_server_replace_id function that receives the Replace ID
8184 payload now sends the NICK_CHANGE notify type also in the file
8185 silcd/packet_receive.c
8187 * Changed WHOIS and IDENTIFY command to support the maximum amount
8188 of arguments defined in protocol specs (3328 arguments). This
8189 fixed a bug that caused problems when there were more than three
8192 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8194 * Added extra parameter, command identifier, to the
8195 silc_client_send_command so that explicit command identifier
8198 Changed that ID list routines uses specific command identifier
8199 when sending WHOIS/IDENTIFY requests to the server so that they
8200 can be identified when the reply comes back.
8202 Affected files lib/silcclient/command.[ch],
8203 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8205 * Added `sender' argument to silc_server_packet_send_to_channel
8206 to indicaet the sender who originally sent the packet to us
8207 that we are now re-sending. Ignored if NULL. Affected file
8208 silcd/packet_send.[ch].
8210 * Added some server statistics support in silcd/server_internal.h
8211 SilcServerStatistics structure and around the server code. Also
8212 send some nice statistics information when client is connecting
8215 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8217 * Fixed channel ID decoding in server's JOIN command reply in
8218 silcd/command_reply.c
8220 * Fixed braodcasting of replace ID payload to not to send it if
8221 we are standalone server in silcd/packet_receive.c.
8223 * Fixed all channel message sending routines to not to send
8224 packets to clients that has router set, since they are routed
8225 separately in the same function earlier. Affects file
8226 silcd/packet_send.c and all channel packet sending functions.
8228 * In USERS reply, res_argv[i] are not allocated, the table
8229 is allocated. Thus changed that free the table, not its
8232 * In server's whois_check and identify_check if the client is
8233 locally connected do not send any WHOIS commands - they are not
8236 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8238 * Fixed some minor bugs in client when sending WHOIS command. The
8239 arguments was in wrong order.
8241 * Removed statis function add_to_channel from server in
8242 silcd/command.c that was previously used with the joining but
8245 * Tested USERS command in router environment successfully with two
8246 routers, two servers and two clients.
8248 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8250 * Reorganized the USERS command and command reply in client library
8251 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8252 When the command is given by user we register a pending command
8253 callback that will reprocess the command after the reply has been
8254 received from the server. When reprocessing the packet we then
8255 display the information. Thus, the USERS information is displayed
8256 now in the command callback instead of in the command reply
8257 callback. The processing of the command is same as previously
8258 when server has sent the command reply in the JOINing process.
8260 * Added to USERS command in silcd/command_reply.c to join the client,
8261 we didn't use to know about, to the channel after we've created
8262 a client entry for it. Also, for clienet we did know already still
8263 check whether it is on the channel or not and add it if not.
8265 * Removed silc_server_command_join_notify as the function and its
8268 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8270 * Changed the client's pending command handling to the same as the
8271 server's pending command handling. It is also now possible to
8272 execute command reply functions from other command reply
8273 function as the function callbacks for commands and command
8274 replies are one and same. The pending commands are not static
8275 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8276 in client connection context. Thus, pending commands are server
8277 connection specific as it is convenient.
8279 Changed the function silc_client_command_pending and
8280 silc_client_command_pending_del and added new function
8281 silc_client_command_pending_check. Removed the
8282 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8285 * Added cmd_ident, current command identifier, to the client
8286 connection context in lib/silcclient/client.h to keep track on
8287 command identifiers used in command sending. Client's command reply
8288 function handling now supports the mandatory command identifiers.
8290 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8291 funtions in client to fully support pending command callbacks.
8293 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8294 as one of the arguments to the application in the command reply
8297 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8298 before first releasing SILC but came back. Now it is removed again
8299 and should come back nomore. The FORWARDED flag was used only
8300 by the JOINing procedure by forwarding the command packet to router.
8301 Now, the JOINing procedure has been changed to more generic (due
8302 to various router environment issues) and FORWARDED is not needed
8303 anymore for anything. The protocol specification is yet to be
8306 Now, removed silc_server_packet_forward from server and the flag
8307 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8309 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Renamed NAMES command to USERS command. The NAMES was named that
8312 due to historical reasons. Now it is renamed. Also, rewrote
8313 parts of the USERS command. The nickname list is not sent anymore
8314 by the server. Only Client ID and mode lists are sent in the USERS
8315 command. Changed this also to the protocol specification.
8317 The client now resolves the names and stuff after it receives
8318 the USERS list from the server when joining to the channel.
8320 * WHOIS and IDENTIFY commands has been changed to support multiple
8321 Client ID's per command. One can now search for multiple users
8322 in the network by sending only one WHOIS or IDENTIFY command.
8323 Changed the code and the protocol specifications.
8325 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8326 uses silc_server_command_whois_parse to parse the request. */
8328 * If normal server, do not parse the WHOIS and IDENTIFY requests
8329 before sending it to the router. Saves some time.
8331 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8333 * Fixed JOIN command on client library. Wrong number of arguments
8334 used to crash the client.
8336 * Added silc_server_channel_has_global function to check whether
8337 channel has global users or not.
8339 * Added silc_server_channel_has_local function to check whether channel
8340 has locally connected clients on the channel.
8342 * The silc_server_remove_from_one_channel now checks whether the
8343 channel has global users or not after given client was removed from
8344 the channel. It also checks whether the channel has local clients
8345 on the channel anymore. If it does not have then the channel entry
8346 is removed as it is not needed anymore.
8348 * The silc_server_notify now checks on JOIN notify whether the joining
8349 client is one of locally connected or global. If it is global then
8350 the channel has now global users on the channel and that is marked
8351 to the channel entry. Also, it now saves the global client to
8352 global list who is joining and JOINs it to the channel. This is
8353 for normal server, that is.
8355 Changed silc_server_send_notify_on_channel,
8356 silc_server_packet_relay_to_channel and
8357 silc_server_packet_send_to_channel check if we are normal server
8358 and client has router set (ie. global client) do not send the
8359 message to that client, as it is already routed to our router.
8361 * Implemented LEAVE notify type handling in silc_server_notify
8364 * Tested LEAVE command in router environment successfully. Tested
8365 with two routers, two servers and two clients.
8369 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8371 * Implemented SIGNOFF notify type handling in silc_server_notify
8374 * silc_server_remove_id now removes the client entry from all channels
8375 it has joined and thusly sends SIGNOFF notify type.
8377 * Rewrote the NAMES list generation in server by removing two excess
8378 loops. The lists are created now inside one loop.
8380 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * silc_server_remove_channel_user checks now also global list
8383 for channel and client.
8385 * silc_server_new_channel_user checks now both local and global
8386 list for channel and client. Fixed a bug in client id decoding.
8387 Used to decode wrong buffer.
8389 * silc_server_channel_message checks now both local and global
8390 list for channel entry.
8392 * Tested channel joining (hence JOIN) in router environment
8393 successfully. Tested with two routers, two servers and two
8396 * Tested channel message sending in router environment successfully.
8398 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Added silc_server_save_channel_key into server.[ch] to save the
8401 received channel key in Channel Key payload processing. It is
8402 also used in JOIN command reply handling.
8404 Equivalent function silc_client_save_channel_key added into
8405 client.[ch] into client library.
8407 * Changed JOIN command reply to send information whether the channel
8408 was created or not (is existing already) and the channel key
8409 payload. Changed protocol specs accordingly.
8411 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8412 the request was sent by ID and not by nickname. Crashed on
8415 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8417 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8418 now correctly save the received data.
8420 * silc_server_free_sock_user_data now notifies routers in the
8421 network about entities leaving the network.
8423 At the same time implemented functions silc_server_remove_id
8424 and silc_server_send_remove_id to receive and send REMOVE_ID
8425 packets. The packet is used to notify routers in the network
8426 about leaving entities. The ID removed will become invalid in
8429 * Added function silc_idlist_del_server into server. Removes and
8430 free's server entry from ID list.
8432 * silc_server_private_message function now checks, if we are router,
8433 that the destination ID really is valid ID, naturally.
8435 * In router when NEW_ID packet is received (for new client) the
8436 hash of the Client ID is saved in the ID Cache but the
8437 client->nickname is set to NULL, instead of putting the hash
8440 IDENTIFY command now also checks that client->nickname must be
8441 valid. If it is not if will request the data from the server who
8442 owns the client. Added new function
8443 silc_server_command_identify_check.
8445 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8446 to set the command to already allocated Command Payload.
8448 * Tested private message sending in router environment with two
8449 routers, two servers and two clients. Fixed minor bugs and now
8452 * Fixed segfault from client's NAMES command. Used to crash if
8455 * Forwarded packets must not be routed even if it is not destined
8456 to the receiver. Changed server code comply with this.
8458 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8460 * Added `require_reverse_mapping' boolean value to ServerParams
8461 structure. If TRUE (not default) the server will require that
8462 the connecting host has fully qualified domain name.
8464 If the reverse mapping is not required and hostname could not be
8465 found the IP address is used as hostname.
8467 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8469 * Implemented version string checking to both client and server.
8470 The check is incomplete currently due to the abnormal version
8471 strings used in development version of SILC.
8473 * Changed all command functions in server to use the new
8476 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8478 * Changed char *data to unsigned char *data in ID Cache system to
8479 support binary data as ID Cache data. Changed code to support
8480 binary data in lib/silccore/idcache.c.
8482 * Renamed silc_server_packet_relay_command_reply to
8483 silc_server_command_reply as it is normal packet receiving
8484 function. Rewrote the function to accept command replys for
8485 servers and not only for clients.
8487 * Mark remote router always as registered server if we are connecting
8488 to it. Otherwise, commands sent by the router to us are ignored.
8490 * All ID List find routines now returns the ID Cache Entry pointer
8491 as well if requested.
8493 * WHOIS command works now in router environment, tested with two
8494 routers, two servers and two clients.
8496 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8497 in router environment (as it is almost equivalent to WHOIS) but
8498 hasn't been tested thoroughly. Added new functions:
8500 silc_server_command_identify_parse
8501 silc_server_command_identify_send_reply
8502 silc_server_command_identify_from_client
8503 silc_server_command_identify_from_server
8505 * Disabled route cache adding because adding two different ID's with
8506 same IP replaces the old cache entry thus giving wrong route.
8507 The entry->router->connection is always the fastest route anyway
8508 so route cache may not be needed. Of course, new routes maybe
8509 established after receiving the ID when the entry->router->connection
8510 might not be anymore the most optimal.
8512 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8514 * Add route cache for received ID for fast routing.
8516 * Added silc_server_packet_route to route received packet on router
8517 that is not destined to us.
8519 * Renamed silc_server_get_route to silc_server_route_get.
8521 * Added id_string and id_string_len fields into SilcServer to
8522 include encoded ServerID for fast comparing without excess
8523 encoding of the ID's.
8525 * Cleaned up WHOIS command on server side. Added following static
8528 silc_server_command_whois_parse
8529 silc_server_command_whois_check
8530 silc_server_command_whois_send_reply
8531 silc_server_command_whois_from_client
8532 silc_server_command_whois_from_server
8534 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8535 arguments in command replies. All command functions should be
8536 updated to use this macro.
8538 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8540 * Minor typo fixes on command reply handling on server.
8542 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8544 * Added silc_server_command_add_to_channel internal routine to add
8545 the client to the channel after router has created the channel and
8546 sent command reply to the server.
8548 * Added generic silc_server_send_command to send any command from
8551 * Use static buffer with ID rendering instead of duplicating data.
8553 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8555 * Fixed a channel user mode bug when joining to a channel server gave
8556 everybody channel founder rights, oops.
8558 * We mark ourselves as the router of the incoming server connection
8559 if we are router ourselves. This way we can check in some packet
8560 sending functions whether it is locally connected server. For
8561 incoming router connections we put NULL.
8563 * For router sending packets locally means now always sending the
8564 packet cell wide; to local clients and local servers. For normal
8565 server sending packet locally means sending it to only local
8568 * Fixed the JOIN command to really work in router environment. If the
8569 channel is created it is always created by the router. Router is
8570 also responsible of making the initial joining to the channel,
8571 sending JOIN notify to the sending server and distributing
8572 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8573 does not exist server doesn't do anything else but forward the
8574 command to the router which performs everything.
8576 * Added silc_server_send_channel_key function to send the Channel Key
8579 * Added silc_server_create_channel_key to create new channel key. The
8580 channel key is now re-generated everytime someone joins or leaves
8581 a channel, as protocol dictates. Note: channel->key_len is the
8584 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8586 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8587 packet_receive.[ch] to separate packet sending and receiving
8588 routines. The server.[ch] now includes everything else including
8589 actual packet processing (writing and reading data) and other
8592 Renamed silc_server_private_message_send_internal to
8593 silc_server_send_private_message. The routine is still though
8594 used only to relay private messages as server does not send
8595 private messages itself.
8597 Renamed silc_server_new_channel to silc_server_create_new_channel
8598 and added new function sicl_server_new_channel that handles the
8599 incoming New Channel packet. Added also new sending function
8600 silc_server_send_new_channel to send New Channel Payload.
8602 * Added new function silc_server_notify to process incoming notify
8603 packet to the server/router. Server may then relay the notify
8604 to clients if needed.
8606 * Added new function silc_server_new_channel_user to process incoming
8607 New Channel User packet. Router will redistribute the packet and
8608 send JOIN notify to its local clients and locally connected servers
8609 if needed. Normal server will send JOIN notify to its local client
8610 on same channel when received this packet. Added also corresponding
8611 sending function silc_server_send_new_channel_user to sent the
8614 * Added boolean route argument to send_notif_to_channel and
8615 packet_send_to_channel functions to attempt to route the packet
8616 if it is TRUE and send only locally if it is FALSE.
8618 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8620 * silc_server_replace_id now broadcasts the received replace ID
8621 packet if it is not broadcast packet already. The router must
8622 broadcast to inform other routers about changed ID.
8624 * Added backpointer to server's router into SilcServer context in
8625 silcd/server_internal.h.
8627 * Fixed silc_server_packet_broadcast to send correct broadcast
8630 * The channel key is now distributed to the local client as soon
8631 as it is received from the router (in router environment) so that
8632 no other packet may be sent for the channel until client has
8635 * silc_server_remove_channel_user now broadcasts the received
8636 Remove Channel User packet if it is not broadcast packet already.
8637 The router must broadcast to inform other routers about removed
8640 * Added users field into SilcPacketContext that is a reference count
8641 of the context. One can increase the reference count by calling
8642 silc_packet_context_dup which is now changed to just increase the
8643 reference count instead of duplicating the data. The reference
8644 count is decresed by calling silc_packet_context_free that will
8645 free the data after the reference count hits zero.
8647 For now on the packet context and everything allocated into it
8648 (including the raw packet from network) must be freed by calling
8649 the new silc_packet_context_free function. Added also new function
8650 silc_packet_context_alloc that must be used now to allocate the
8651 context. This also means that if a routine is asynchronous from
8652 silc_[client/server]_packet_parse_type the packet context must
8653 be duplicated by calling silc_packet_context_dup. Otherwise it
8654 gets free'd after silc_[client/server]_packet_parse_type returns.
8655 Also, one must remember that if packet is duplicated then its
8656 reference count must be decresed by calling the free function as
8657 many times as it was duplicated.
8659 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8660 from both client and server.
8662 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8664 * Made joining to a channel working in router environment.
8666 * Cleaned up JOIN command on server side and create function
8667 silc_server_command_join_channel internal routine to make the
8670 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8672 * Changed silc_command_pending list to SilcDList. Also, added
8673 `ident' field to SilcServerCommandPending structure to identify
8674 the reply and to call correct callback.
8676 Added silc_server_command_pending_check function to replace the
8677 corresnponding macro. The silc_command_pending list is not
8680 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8681 to set identifier to previously allocated Command Payload. It
8682 is used to set identifier for command when resending Command
8685 * Added silc_command_payload_encode_payload to encode Command
8686 Payload buffer from SilcCommandPayload structure.
8688 * Added silc_argument_payload_encode_payload to encode Argument
8689 payload buffer from SilcArgumentPayload structure.
8691 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8693 * Changed WHOIS command to support router connection on server side.
8694 The whois request is always sent to router unless the server is
8695 standalone server. After server has received the reply from the
8696 router will it send the reply to the client.
8698 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8699 broadcast received broadcast packet. The function is used only
8700 by router. The broadcast packet is always sent to the router's
8703 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8704 render given ID to printable string, for log files for example.
8706 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8708 * Made basic router to router connections working. At least they
8709 can now connect to each other but nothing really works the way
8710 they are supposed - yet.
8712 * Added new initiator token to RouterConnection configuration
8713 file in silcd/serverconfig.[ch]. It is used to tell whether we
8714 are the initiator to the remote router or whether we'll expect
8715 the other end to connect.
8717 * Moved registering of listener task to silc_server_init, hence
8718 the server starts listenning as soon as it is run, even if it
8719 does not have connections to other routers. Let's see how well
8722 * Changed default connection retry timeouts for more suitable in
8725 * Removed cipher and such arguments from silc_idlist_add_client
8726 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8727 Added new function silc_idlist_add_data to add the keys and stuff
8730 * Added SilcIDListData structure and added it to SilcClientEntry
8731 and SilcServerEntry as their first field in the structure. This
8732 way we can explicitly cast the ID entries to the SilcIDListData
8733 structure and get common data for the entries. In past, we had
8734 to first check what type of connection it is and then cast it to
8735 correct ID entry type. Now, we can directly cast the opaque
8736 pointer to the SilcIDListData (no matter what ID entry it actually
8737 is) and get the data needed.
8739 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8741 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8742 in some circumstances even if threre were timeout tasks, though not
8743 IO tasks, but tasks anyway. Now fixed.
8745 * Defined SilcServerConnection structure to hold connection specific
8746 stuff about directly connected servers and routers. The definition
8747 is currently in silcd/server_internal.h. I thought about having
8748 a bit more important role fro this struct but for now it is used
8749 only when connecting to other server (or router actually).
8751 * Added connecting retry support in server when connecting to
8752 router(s). The retry feature implement exponential backoff
8753 algorithm. Also, added SilcServerParams structure to hold default
8754 parameters for server. For now, it include these retry settings
8755 and are hard coded. After server is moded to be as Silc Server
8756 Library this structure will be more important.
8758 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8760 * Changed client librarys channel->clients table to SilcList and
8761 changed code accordingly.
8763 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8765 * Changed client's channel table to SilcList and changed code
8766 accordingly. Also changed SilcChannelClientEntry to include back-
8767 pointer to the channel so that client entry can use that structure
8768 as list as well and we have fast cross-reference to the channel.
8769 This change dramatically decreased the complexity of channel
8770 handling with client entry and vice versa (removed one extra
8771 loop when searching for channel entry from many functions).
8773 * Changed server->sim from table to SilcDList and changed code
8776 * NAMES command can now be used from user interface. It will show
8777 the user list on the channel, neatly.
8779 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8780 Code now saves realname of the user if it becomes available.
8782 * Renamed configure.in to configure.in.pre and made ./prepare
8783 script to automatically add correct version string to
8784 configure.in which it creates from configure.in.pre.
8786 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8788 * NAMES command reply now shows users mode with the nickname when
8791 * Moved silc_client_ch[u]mode[_char] functions from
8792 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8793 place sucks, they are utility functions and should be in some
8796 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8798 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8801 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8805 * Added TRQ (efficient deque and list library) into lib/trq. This is
8806 a very good list library that is currently used in the SILC. Defined
8807 SilcList API over the library because I didn't like the API very
8808 much. See lib/trq/silclist.h for the API and examples of how to
8809 use the API. Fixed various places in the code to use the new
8810 SilcList API. The SilcList is meant for lists that has a structure
8811 already defined as a list. It is not suitable to add just some
8812 context to the list (in TRQ, the context is the list actually).
8814 So, I defined SilcDList that can be used for the purpose where
8815 predefined list structure does not exit. This can be used as
8816 such list. Now some context just can be added to the SilcDList.
8817 Currently this list is not used in the SILC just yet, though there
8818 are a lot places where this can replace dynamically allocated
8819 tables and I will fix these places, later, to use SilcDList.
8820 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8821 and use TRQ internally).
8823 Also fixed some annoying warning messages that the original TRQ
8824 code generated. Also minor changes to TRQ's Makefile.in.
8826 * Added support for querying by Client ID to both WHOIS and
8827 IDENTIFY commands into server, as required by the protocol.
8829 * Removed method function pointers from SilcBuffer structure. They
8830 weren't used to anything and just increased the context size for
8831 no good reason. This change also made silc_buffer_alloc and
8832 silc_buffer_free functions inline functions.
8834 * Disabled command flooding detection support until it's fixed so
8835 that it accepts commands in but does not execute them more than once
8838 * Added silc_net_localhost(), to return local hostname, into
8839 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8840 that must be initialized before calling silc_client_init.
8842 * Added new function: silc_server_send_notify_on_channels to send
8843 notify messages to all channels client has joined. It is assured
8844 that the message is sent only once per client.
8846 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8847 lib/silcutil/silcutil.[ch] as silc_format function. The new
8848 function is generic and is used by server as well, not only by
8849 the logging routines.
8851 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8852 the provided version string was not acceptable. Added new function:
8853 silc_ske_check_version into lib/silcske/silcske.h. The function
8854 must be implemented by the application (client or server) and it
8855 does not reside in the SKE library. The function checks the version
8856 string remote end sent.
8858 * Added back pointers (to opaque context and to SilcSocketConnection)
8859 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8861 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8862 duplicate packet context structure.
8864 * Changed `notify' client operation to send same arguments as client
8865 receives from server except for ID's. ID's are mapped to correct
8866 ID entry and that is returned. Also, if channel entry is not sent
8867 by server but the notify is for channel the channel entry is sent
8868 to application (otherwise application doesn't know that it is for
8869 channel (library gets it from packet's Destination ID)).
8871 * Added silc_client_remove_from_channels into client library to
8872 remove a client from all channels it has joined to. Used when
8873 received SIGNOFF notify from server. Added also new function
8874 silc_client_replace_from_channels to replace old ID entry with
8875 new ID entry on all channels. Used when received NICK_CHANGE
8878 * Fixed ID Cache list handling in silc_idlist_get_client in
8879 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8880 to get (or query) client by ID.
8882 * Updated TODO list.
8884 * Added connection authentication status message defined by the
8885 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8886 support for these into the code in client and server side.
8888 * Added generic function silc_client_send_command to send any command
8889 with variable argument list. Application should use this function
8890 to send commands if the command functions provided by the library
8891 does not suite for the application's user interface needs.
8893 * Added new `failure' client operation. Application is notified about
8894 received failure packet if client is executing a protocol. In this
8895 case the protocol's execution has failed.
8897 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8898 is required by the protocol.
8900 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8901 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8904 * Added status flag to SilcSKE object to indicate realtime status
8905 of the SKE protocol.
8907 * Application receives now exactly same command reply arguments as
8908 the library receives from server. However, if ID is received the
8909 corresponding ID entry is returned to the application (eg. Client
8910 ID is mapped to correct SilcClientEntry entry and that is returned).
8911 Changed command_reply client operation due to this change.
8913 * Changed all ID's in commands and in command replys as ID Payloads.
8914 Change affected both client and server side codes.
8916 All ID's sent in SILC network (with execption of ID's in SILC
8917 Packet header) are sent in ID Payload to support variable length
8920 * Server now notifies nick changes and notifies all clients on
8921 the channels about the new nickname (about the new Client ID,
8924 * Implemented CMODE command to change channel modes. Supports all
8925 channel modes defined by the protocol specs except ban and invite
8926 lists. (Also, private channel key mode is supported but support for
8927 setting private channel key in client is missing, thus, this mode
8928 has no effect on client side (except that server requires that the
8929 client uses private channel key and normal channel traffic does not
8932 Also, invite mode works per se, but INVITE command does not work
8933 yet correctly, so you can set channel as invite only channel but
8934 inviting clients to the channel does not work (it is yet to be
8935 thought what's the best way to do it).
8937 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8938 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8939 Implemented CUMODE command to change user's mode on the channel.
8940 Supports all modes defined by the protocol specs.
8942 * Added NAMES command reply to return users modes on the channel.
8944 * Removed unnecessary and slow ciphers from lib/silccrypt.
8946 * Set SO_KEEPALIVE option to connection sockets by default.
8948 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8950 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8951 redefined the Notify Payload into protocol specs.
8953 * Added silc_id_payload_parse_id to get ID directly from raw
8956 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8958 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8959 accept searching by Client ID as well.
8961 * Added support for LEAVE and SIGNOFF notify types in client library.
8963 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8964 to parse ID Payload from raw data.
8966 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8968 * Added flags parameter into silc_ske_assemble_security_properties
8969 function in lib/silcske/silcske.[ch].
8971 * Changed notify client operation to fit better for notify messages
8972 sent by server. The notify payload received from server is now
8973 passed to the application (after parsing it to SilcNotifyPayload).
8974 It is application's responsibility to retrieve the arguments
8975 from the payload and show the message the way it wants. The message
8976 sent by server is implementation specific.
8978 * Changed public keys to comply with the protocol specification.
8979 Old public keys are not supported anymore and are not compatible.
8981 * Removed nickname from Channel Payload as the latest draft removed
8982 it. The client must resolve the nickname from the NAMES command
8983 reply received when it joined the channel.
8985 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8987 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8989 * Fixed some errors in protocol specification drafts.
8991 * Created lib/silccore/silcnotify.c to implement Notify Payload
8992 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8993 generic payloads described by protocol specifications. The file
8994 includes implementations for ID Payload and Argument Payload.
8996 * Changed Command Payload implementation to use the new Argument
8997 Payload. Changed command_xxxx_payload to command_payload_xxxx
8998 to comply with SILC coding conventions.
9000 * Added suppport for Argument Payload handling in Notify Payload
9001 implementation as protocol requires it. Added the new support
9002 into server and client lib as well.
9004 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9006 * Added support for multiple nicknames on same channel. [n] is
9007 added locally to the nickname if there are more than one same
9008 nicknames on the channel.
9010 * Server now sends all nicknames that matched WHOIS request.
9011 Client also shows the list received from server.
9013 * Added TOPIC command to client side. User can now set and show
9014 current topic on channel.
9016 * Added MOTD command to client and server. Also, server sends the
9017 motd when client connects to the server.
9019 * Changed version strings to comply ISO 8601.
9021 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9023 * Fixed protocol error handling in client library. It should now
9024 cope even if the SKE fails for some reason.
9026 * Made new protocol specification drafts for submitting to IETF.
9028 * Implemented TOPIC command to server in silcd/command.c.
9030 * Added two new notify types into lib/silccore/silcnotify.h:
9031 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9032 notify nickname change and topic setting/change on a channel.
9034 * API change of command_reply operation in client library. The
9035 application gets now the status type received from server as well.
9037 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9039 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9041 * Cras fixed and optimized the packet handling even further and
9042 it should work now. Minor change to the prototype of function
9043 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9045 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9047 * Added new function into lib/silcutil/silcschedule.[ch]:
9048 silc_schedule_with_fd to select() a specified fd. The function
9049 returns after timeout expires or data arrives or goes. The
9050 function is used by packet routines to wait that all data is
9051 received from network.
9053 * Fixed data reading from network in lib/silccore/silcpacket.c.
9054 The code now assures that all data is read from the fd and then
9055 continues packet processing. This was a bug fix since the code
9056 used to drop some data in some circumstances.
9058 * Added new function into lib/silcclient/client.[ch]:
9059 silc_client_start_key_exchange to start key exchange after
9060 connection has been established to server. The code internally
9061 now uses this funtion but its main purpose was to provide it
9062 for applications that perform their own connecting. After
9063 application has created a connection it merely calls this
9064 function to start the key exchange between client and server.
9065 The library takes care of everything else after that.
9067 Updated also lib/silcclient/README to explain the usage of
9070 * Do not send to application information that connection has
9071 been established. Application gets notified it by connect
9074 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9076 * Applied cras's patch to add silc_schedule_one function. The
9077 function runs scheduler once and returns.
9079 * Fixed the scheduler after cras messed it up. The timeout
9080 handling works now as it's supposed to work.
9082 * Added into lib/silccore/ silcnotify.h to include notify
9083 message types support. Changed silc_server_send_notify*
9084 functions, in server.[ch], to support those new notify types.
9085 Added the support for the notify types into client library,
9086 as well. Added new notify client operation into ops.h in
9089 * Changed silc_server_packet_send_to_channel to send normal
9090 packets instead of just channel message packets. The function
9091 is now used to send the notify packets to channels. It is not
9092 used to send channel message packets anymore, as server never
9095 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9096 va_arg()s as it seems to require it nowadays. I guess, if SILC
9097 is compiled with older va_arg() the new code should work anyway.
9099 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9101 * Splitted core library. Core library (lib/silccore) includes
9102 now only SILC protocol specific core (and common) components.
9103 Created new utility library (lib/silcutil) that includes more
9104 generic purpose stuff. The stuff for util library was taken
9105 from the old core library. This was minor and easy split.
9107 * Created SILC Client Library (lib/silcclient) that includes
9108 implementation of the SILC client without user interface. This
9109 was major move from silc/ directory. The code has been changed
9110 so that it is transparent towards the user interface. The
9111 silc/ directory includes now the same user interface as before
9112 and it uses the new client library. Read lib/silcclient/README.
9113 Basicly, the client library performs everything else related
9114 to SILC except user interface handling. Also, configuration
9115 files are considered to be part of user interface and library
9116 does not handle them.
9118 This change also changed a lot of structures, function naming etc.
9119 Most important change was that SilcClientWindow object was
9120 renamed to SilcClientConnection in the client library. Created
9121 also new file lib/silcclient/ops.h. Also added new files
9122 silc/local_command.[ch] and silc/client_ops.[ch].
9124 All these changes were made to make it easier for user interface
9125 designers to create what ever user interface for the SILC client
9128 It is also expected that the server will be moved to lib
9129 directory as well and SILC Server Library will be created;
9130 sometimes in the future.
9132 * Removed Local commands from lib/silccore/silccommand.h as
9133 they are application specific and new client library does not
9134 handle any of those anymore.
9136 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9137 old client implementation in silc/.
9139 * Added support for callback functions in SILC_LOG_* macros.
9140 Application can now set its own callbacks that will be called
9141 instead of using the default functions that will always print
9142 the debug messages to stderr (or stdout). Also, debugging can
9143 now be disabled by setting silc_debug to FALSE and re-enabled by
9144 setting it to TRUE. Note, that logging will still work even
9145 if debugging is disabled.
9147 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9148 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9149 silc_log_reset_debug_callbacks.
9151 * To enable debugging in silc client one must give now -d
9152 option on command line.
9154 * Changed silc_schedule_init to automatically allocate task queues
9155 if they are not allocated before calling it.
9157 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9159 * Added GMP 3.1 into math library.
9161 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9163 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9164 a channel in SILC network. The packet is used by servers and
9165 routers to notify other routers that user has left a channel.
9166 This little feature was missing until now. Added the feature
9167 to protocol specification as well.
9169 Added functions: silc_server_send_remove_channel_user and
9170 silc_server_remove_channel_user into server.[ch].
9172 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9173 lib/silccore/silcpacket.h. However, they are not implemented
9176 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9178 * Fixed joining to a channel and sending channel messages
9179 between server and router. The channel message sending should
9180 now work inside a cell.
9182 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9184 * Fixed the private message sending between server and router.
9185 The private message sending should now work inside a cell.
9187 * Added silc_server_replace_id into server.[ch] to replace
9188 existing ID in the SILC network.
9190 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9191 and silc_idlist_replace_server_id into idlist.[ch] in server.
9193 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9195 * Fixed the server to server connections. Server can again now
9196 connect to router. Router to router connections probably does
9199 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9201 * Added dynamic protocol registering support. Now protocols can
9202 registered and unregistered on the fly. Patch by cras.
9204 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9206 * Added lib/contrib directory to hold routines that some platforms
9207 don't have but are needed by SILC.
9209 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9210 into lin/contrib to provide getopt() and getopt_long() for
9211 those who don't have it.
9213 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9215 * Added AWAY command to client. When away message is set and
9216 client receives a private message packet the client automatically
9217 replies to the sender with the away message.
9219 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9220 bug seemed to be the cause of recent problems when compiling
9223 * Added version detection support to SKE protocol specification
9224 and added the new changes to the SKE implementation as well.
9225 There were other minor changes in the SKE protocol as well.
9227 Many changes in lib/silcske/silcske.[ch] and in
9228 lib/silcske/payload.[ch].
9230 * Added ^U functionality, clear input line. Patch from cras.
9232 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9234 * Mainly small bugfixes on core library. Fixed some debugging
9235 logging and buffer overflow in silclog.c.
9237 * Updated config.sub and config.guess on the distribution tree.
9239 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9241 * Added command lagging support in server. Client may execute
9242 commands now only once in two seconds.
9244 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9246 * Optimized packet reception. MAC computation and checking is now
9247 also more optimized. A lot previously duplicated code is now
9248 used as generic by both client and server.
9250 * Fixed key pair generation in clientutil.c
9252 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9254 * Added into lib/silccore/silcbufutil.[ch] new function;
9255 silc_buffer_realloc.
9257 * Moved generic packet sending/encryption functions to
9258 lib/silccore/silcpacket.[ch] from client and server. Some
9259 rewriting of the functions.
9261 * Moved all generic packet reception/decryption functions to
9262 lib/silccore/silcpacket.[ch] from client and server. The
9263 packet processing is now much cleaner in both client and server.
9264 These were major changes in both client and server.
9266 * Created many common functions in server to do packet sending.
9267 Previously code were duplicated a lot, this has been removed
9270 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9272 * Rewrote major parts of the ID cache system. Don't know
9273 whether it is better now or not but at least the API is more
9276 * Major rewrite on ID cache stuff on client because of the ID
9277 cache API changes. Added idlist.c to client.
9279 * Also major rewrite on ID cache stuff on server as well.
9280 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9281 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9282 in hand, instead they are all put into the ID cache system now.
9283 All server_idlist_* routines uses ID cache now instead of
9284 traversing its own lists (those lists does not exist anymore).
9285 SilcIDList though still exists. Also, SilcXXXEntry's are
9288 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9290 * Finally made the SKE implementation compliant to the protocol
9291 specification. All mp integers are now binary encoded as
9292 opposed being HEX encoded.
9294 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9297 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9298 functions: silc_[encode/decode]_pem. Also added function
9299 silc_encode_pem_file to PEM encode with newlines ('\n') for
9302 * SILC public keys are now encoded either PEM or binary. Same
9303 option is for private keys as well. By default private keys
9304 are binary encoded and public keys PEM encoded. Silly HEX
9305 encoding were removed.
9307 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9308 function to create fingerprints.
9310 * Fixed a bug in SHA1; does not change the original data anymore.
9312 * Partly implemented INFO command on client and server side.
9313 Fixed CLEAR command. Changes to SERVER command; show current
9314 server(s) when giving command without arguments. Added
9315 VERSION command to client.
9317 * Added check to server that unregistered connections cannot
9318 execute commands (unless it is specificly allowed).
9320 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9322 * Fixed screen refresh.
9324 * Fixed channel joining bug from client. On some circumstances
9325 client tried to join to a channel it had already joined.
9327 * Added public key verification process into client's protocol.c.
9328 The client now verifies the public key from user and saves
9329 it into ~./silc/serverkeys/ directory.
9331 Added into: clientutil.[ch]: silc_client_verify_server_key.
9333 * Changed SKE protocol's silc_ske_initiator_finish function
9334 to accept callback function that verifies the received public
9335 key. Removed old silc_ske_verify_public_key function.
9337 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9339 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9340 silc_pkcs_private_key[_data]_set.
9342 * Made the password and public authentication more cleaner in
9343 server's protocol.c.
9345 * Removed historic and obsolete protocol `channel_auth' from
9346 both client and server.
9348 * Removed wrong way of sending command status messages from
9349 server to client in server's command.c. The old way violated
9350 protocol specification.
9352 Changes to silccore/silccommand.[ch]: removed
9353 silc_command_encode_status_payload -> not needed anymore,
9354 changed silc_command_encode_payload_va to accept extra
9355 argument on variable argument list. The argument type must
9356 now be provided to the function. Also, added new function:
9357 silc_command_encode_reply_payload_va which is same as
9358 normal command_encode_payload_va except command status type
9359 is provided as extra argument.
9361 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9363 * Added ~./silc directory handling. The directory includes the
9364 public and private keys for the client.
9366 Added silc_client_check_silc_dir, silc_client_create_identifier
9367 and silc_client_load_keys.
9369 * Implemented SILC protocol compliant public key. Added public
9370 and private key saving to and loading from files.
9372 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9373 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9374 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9375 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9376 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9378 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9379 silc_pkcs_load_[public/private]_key.
9381 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9383 * Added silc_server_get_route (route.[ch]) to get connection
9384 data for the fastest route for given ID.
9386 * Implemented INVITE command on client and server. The command
9387 were re-defined in the SILC Protocol Specification and the
9388 implementation now complies with the specification.
9390 * Implemented PING command on client and server.
9392 * Implemented NAMES command on client and server. The server side
9393 supports currently only normal server not router server yet.
9394 Some changes to NAMES definition in SILC protocol specification.
9396 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9398 * Implemented LEAVE command on client and server.
9400 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9401 again. This change was made to the protocol as well. Server
9402 should not violate the protocol specification anymore.
9404 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9406 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9407 was tested. SOCKS4 was not but should work anyway.
