1 Mon Oct 14 17:55:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Periodically remove the NOATTR status from client entry
4 so that the client may take the attributes in use even after
5 server has resolved them unsuccessfully earlier. Affected
6 file silcd/server_query.c and idlist.h.
8 * Moved sha1hash and md5hash from client->internal to
9 SilcClient for application usage. Affected files are

22 strings into a buffer which size is automatically increased.
23 Affected file lib/silcutil/silcbuffmt.[ch].
25 * Added implementation of VCard (RFC 2426) which can be used
26 as part of Requested Attributes in WHOIS command. Affected
27 file lib/silcutil/silcvcard.[ch].
29 Fri Oct 11 23:52:17 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Some strncat -> silc_strncat changes our the core and
34 * Added SILC_SKE_STATUS_SIGNATURE_ERROR and OUT_OF_MEMORY
35 errors. Added better error printing to SKE library.
36 Affected files lib/silcske/silcske.c, silcske_status.h and
39 * Save the PKCS key length even if only private key is set to
40 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
42 * Fixed the usage of silc_pkcs_get_key_len since it returns the
43 length in bits not in bytes. Affected files are
44 lib/silcske/silcske.c, lib/silccore/silcauth.c and
47 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
49 * Added silc_attribute_payload_encode_data to directly encode
50 the data into the attributes buffer. Renamed function
51 silc_attribute_payload_parse_list to silc_attribute_payload_parse.
52 Affected files are lib/silccore/silcattrs.[ch].
54 * silc_hash_table_find_foreach calls the foreach function now
55 once even if the nothing was found with context set to NULL.
56 Affected file lib/silcutil/silchashtable.[ch].
58 * Remove the RESOLVING flag from client entry after received
59 the Requested Attributes from the client. Fixed memory leak
60 in client entry freeing. Affected files silcd/server_query.c
63 * Added Requested Attributes support into SILC Client Library.
64 It is not able to send requested attributes in WHOIS command,
65 and also receive and process requested attributes. Added
66 silc_client_attribute_[add|del] and silc_client_attributes_get
67 functions. Added also `ignore_requested_attributes' to the
68 SilcClientParams to not use attributes in client. Affected
69 files are lib/silcclient/command.c, client_attrs.[ch],
70 silcclient.h, client_internal and client.[ch].
72 * Changed the silc_client_get_client_by_id to support Requested
73 Attributes, it takes them as argument now. Affected file
74 is lib/silcclient/silcclient.h, and idlist.c.
76 * Added -details option to WHOIS command in Irssi SILC Client
77 to support the requested attributes. By default it requests
78 all attributes. Affected file lib/silcclient/command.c and
79 irssi/doc/help/in/whois.in.
81 Tue Oct 8 17:58:28 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
83 * Add also SERVICE attribute for server-constructed attribute
84 data. Also digitally sign the attributes and add
85 SERVER_DIGITAL_SIGNATURE attribute. Affected file is
88 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
90 * Changed the silc_attribute_payload_encode to support list
91 of attributes (function may be called several times to add
92 a new attribute). Removed the silc_attribute_payload_encode_list
93 function. The encoding function now also automatically encodes
94 the data, so the caller does not need to do that. Affected
95 files lib/silccore/silcattrs.[ch].
97 * Added support for replying on behalf of the user to the
98 Requested Attributes in WHOIS command in the server. Affected
99 file silcd/server_query.c.
101 * SILC_NOT_IMPLEMENTED macro use SILC_LOG_INFO now instead of
102 SILC_LOG_DEBUG. Affected file lib/silcutil/silclog.h.
104 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Don't swtich to become primary router if we are backup if
107 decryption error has occurred. Affected file silcd/server.c.
109 * Fixed a bug in backup router IP address comparison in
110 silc_server_backup_get.
112 Save now also the port of the server/router and use that
113 in comparison as well. Affected file silcd/server_backup.c.
115 * Normal server now reconnects to backup router automatically
116 if connection is lost to it. Affected file silcd/server.c.
118 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
120 * If packet processing fails (like integrity check fails)
121 the connection is closed now. Affected files are
122 lib/silccore/silcpacket.c and silcd/server.c.
124 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

133 Added server_query.[ch] which provides one interface for
134 querying information using all three commands.
136 * Changed all "typedef unsigned char" in core library to
139 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
141 * Added silc_strncat into lib/silcutil/silcstrutil.[ch].

146 Wed Sep 18 18:28:04 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
148 * Resumed client packet handling from server put the resumed
149 client on wrong list on router and caused the client not
150 be present on the network anymore. Now fixed to put the
151 client to correct list. Affected file silcd/packet_receive.c.
153 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
155 * Various cleanup in error message output in config parsing code
156 and in server init code. Fixed error log files containing
157 too many newlines ('\n') in some situations. Affected files are
158 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
160 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Use the reverse lookupped hostname in client internals
163 instead of one user provided us as remote server name.
164 Affected file lib/silcclient/client.c.
166 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Added 'app_context' to silc_schedule_init. It is an
169 application specific context that is delivered to application
170 in task callback functions. Affected files are
171 lib/silcutil/silcutil.[ch].
173 * The hb_context in SilcSocketConnection is not freed
174 automatically anymore (application must free it). Freeing
175 it automatic is inconsistent. Affected files are
176 lib/silcutil/silcsockconn.[ch].
178 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Added support for removing explicitly added client connections
181 in rehash and closing the client connections if they were
182 unconfigured in the rehash. Affected file silcd/server.c.
184 * Added support for aborting automatically pending commands
185 that never receives the reply (to avoid memory leaks).
186 Added also silc_server_command_pending_timed to set the
187 specific timeout for pending command. Affected files are
188 silcd/command[_reply].[ch].
190 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
191 specs and lib/silccore/silcstatus.h.
193 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Changed the silc_get_time to accept time value as argument
196 or if zero is sent return current local time. Affected
197 file lib/silcutil/silcutil.[ch].
199 * Added STATS command to client library and Irssi SILC client.
200 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
202 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
204 * Assure that channel key is set before sending it. May
205 crash server otherwise. Affected file silcd/packet_send.c.
207 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Assure that endless loop cannot happen with detached client
210 resolving on normal server. Added idlist status
211 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
212 silcd/idlist.h and silcd/packet_receive.c.
214 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Incoming file transfer request cannot use same session as
217 the sending session. This can happen when sending file to
218 yourself. Crashed the client on quit. Affected file
219 lib/silcclient/client_ftp.c. Bug #24.
221 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
223 * Implemented the draft-riikonen-precense-attrs draft and
224 the Attribute Payload into the lib/silccore/silcattrs.[ch].
226 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Distribute the SERVER_SIGNOFF notify also to local backup
229 routers from the primary router. The backup router may not
230 have the signing of local server directly connected and need
231 to know about the signoff. Affected file silcd/server_util.c.
233 * Use the primary router as the origin of the locally connected
234 server when it is disconnecting from the backup router since
235 that's where it really is coming from. Now the clients from
236 the disconnecting server are removed correctly and "shadow"
237 clients are not left to the backup router. Affected file
240 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
242 * If normal server is standalone and found existing but disabled
243 channel, do not re-create the channel since it creates
244 duplicate same channels. Affected file silcd/server.c.
246 * Added anonymous client connections support to server. New
247 "anonymous" configuration option to ConnectionParams section
248 added. If set to true, the username and hostname information
249 of the client will be scrambled and anonymous user mode is
250 set automatically to the user. Affected files are
251 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
253 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
255 * In JOIN notify handling, mark that the cache entry of the
256 client cannot be expired. Can cause crashes on normal
257 server (asserts client->channels). Affected file is
258 silcd/packet_receive.c.
260 * From now on distribution versions are used as protocol versions
261 instead of by default using the Toolkit base version as protocol
262 version. Affected file prepare.
264 * Do not set the locally resolved hostname for local client
265 entry but take what server sends. This way the real hostname
266 is showed in WHOIS for yourself. Affected file is
267 lib/silcclient/idlist.c and lib/silcclient/client.c.
269 * Resolve local info with IDENTIFY when connecting to server.y
271 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
273 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
274 for implied search (not needed on platforms which has native
275 pthreads library). Use --without-pthreads to disable threads.
276 Affected file is configure.in.pre
278 * Fixed --with-iconv on platforms which need to bypass (broken)
279 native iconv(). Affected file is configure.in.pre
281 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Moved -C option parsing in Irssi SILC client at same time
284 as other options. The UI was initialized earlier and caused
285 problems on command line. Bug #16. Affected file is
286 irssi/src/silc/core/silc-core.c.
288 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
290 * Added global variable silc_log_timestamp that tells silclog
291 wether to print or not the timestamp in the logging files.
292 Affected file lib/silcutil/silclog.[ch].
294 * Added silcd configuration option Timestamp in the Logging
295 section. Affected file silcd/serverconfig.[ch],
296 doc/example_silcd.conf.in.
298 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Fixed fingerprint checking to check for entirely empty
301 fingerprint instead of two first bytes when determining
302 if it is set. Bug #18. Affected file silcd/command.c.
304 * Fixed duplicate PKCS name registering to not allow it.
305 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
307 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
309 * Conditionalize non-gcc compiler optimizations for various
310 platforms, enable those commented out. Cleanups.
311 Affected file lib/silcmath/mpi/configure.in
313 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
315 * silc_rng_exec_command() left zombie processes if command
316 didn't generate any output. Affected file
317 lib/silccrypt/silcrng.c
319 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
321 * Rewrote iconv checking, introduce --with-iconv for systems
322 which rely on libiconv. Check if iconv() provided by libc
323 is good enough, otherwise demand libiconv. Affected file
326 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
328 * Search for ldopen() also in libc. This enables SIM support
329 on *BSD systems. Based on patch from Alex Zepeda. Affected
330 file configure.in.pre
332 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
334 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
335 This fixes prepare on *BSD systems. Affected file
338 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
340 * More fixed for not having purge timeout for global clients
341 that are on channel. Affected files silcd/command_reply.c
344 * Fixed the rekey protocol to work with backup router connections.
345 Rekey packets are now allowed on disabled connections as
346 well. Affected files silcd/packet_send.c and server.c.
348 * Do not switch to be as backup router when shutting down and
349 closing the primary connection. Affected file silcd/server.c.
351 * Fixed memory leaks in backup router deleting. Added
352 silc_server_backup_free to free all data during shutdown of
353 server. Affected files silcd/server_backup.[ch].
355 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
357 * Do not process commands if the sock->user_data is NULL.
358 Affected file silcd/command.c.
360 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
362 * Fixed buffer overflow and security problems (loosing bits
363 in CFB encryption) in SILC RNG. Problems reported by
364 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
366 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
368 * Added yet more checks that client is not expired on global
369 list if it is on channels. Affected file is
370 silcd/command_reply.c.
372 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Merged c0ffee's MIME signal patch which adds support for
375 sending also MIME messages in Irssi SILC Client, and handling
376 received MIME messages in a signal (and perhaps doing something
377 to non-textual MIME messages).
379 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Fixed pending command deletion in server and client library
382 to check the whole list instead of breaking after first found.
383 The affected files are silcd/command.[ch] and
384 lib/silcclient/command.[ch].
386 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
388 * Return NO_SUCH_CHANNEL error in USERS for channel that is
389 secret or private, otherwise it's possible to find out
390 whether a secret channel exists or not. Affected file
393 * If CMODE change fails during the mode setting, assure that
394 the old mode mask is set for the channel back. Affected
395 file silcd/command.c.
397 * Fixed passphrase saving on +a channel on normal server
398 after successful JOIN command. Affected file silcd/command.c.
400 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
402 * Remove server/router operator privileges in DETACH command,
403 since it's possible to resume to server where these
404 privileges would not be allowed for the client. Affected
405 file silcd/command.c.
407 * Do not set to wait for backup in rehash of the server.
408 Affected file silcd/server.c.
410 * Do not check listener sockets when counting how many
411 socket connections we have. Affected file is
414 * Do not announce disconnected clients that are remaining
415 in history (for WHOWAS). This is because SIGNOFF notify
416 for these has been sent earlier already. Affected file
419 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Buffer overflow with CUMODE command's mode->mode character
422 conversion. Reported by Ville Räsänen. Affected file
423 lib/silcutil/silcutil.c.
425 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Allow heartbeat packets to go disabled connections anyway.
428 Affected files silcd/server.c and silcd/packet_send.c.
430 * Do not broadcast New Channel packets with List flag set
431 in the packet to backup routers. The router must check
432 for the correctness of the packets before sending them.
433 It is possible that router will have enforce Channel ID
434 change and this would cause desync in the backup router.
435 Affected file silcd/packet_receive.c.
437 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
438 are handled in list parsing. They are not list packets
439 anymore. Affected file silcd/packet_receive.c.
441 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Stop waiting for backup router through the timeout, not
444 directly after backup router has arrived. Affected file
447 * Do not re-create channel keys and send them when removing
448 clients in server shutdown. Affected files are
449 silcd/server_internal.h and silcd/server_util.c.
451 * Notify distribution to backup routers was missing from
452 the silc_server_send_notify_dest function which caused
453 desyncing problems with backup router. Affected file is
456 * The client's channel removing was working wrong on
457 backup router. It assumed that it doesn't know global
458 information but backup router does know. For this reason
459 it could remove channel when it wasn't supposed to do that.
460 Affected file silcd/server.c and silcd/server_util.c.
462 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Stop for a couple seconds after badkup router has become
465 primary router. Affected file silcd/server.c.
467 * Added silc_server_remove_servers_by_server, which is used
468 to remove servers originated from some other server. Also
469 clients of those servers can be removed too. Affected file
470 silcd/server_util.[ch].
472 * When removing clients after a server has signed of remove
473 also all servers behind that server (unless they are known
474 to be available locally), and send SERVER_SIGNOFF for each
475 of the server separately. Also the signed off clients are
476 sent now separately per signed off server. The affected files
477 are silcd/server.c and silcd/server_util.[ch].
479 * All servers added with silc_idlist_add_server must always
480 have both "router" and "connection" pointers set. Otherwise,
481 bad server entries may be left around in the cache.
482 Affected file silcd/command_reply.c.
484 * Do not create the channel key in NEW_CHANNEL packet
485 processing if the channel is empty. Affected file
486 silcd/packet_receive.c.
488 * Completed backup router support for standalone routers.
489 Supports also servers in the cell that do not use the backup
492 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
494 * Fixed a bug in silc_string_regexify which did not add '^'
495 at the start of each string, and thus the matching was
496 not explicit. For example ban list iikone@*!*@* would
497 match also "priikone", which is wrong, it would have to be
498 *iikone@*!*@* to match also "priikone". Affected
499 file lib/silcutil/unix/silcunixutil.c.
501 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Enable all local server connections before updating client
504 caches when we've become backup router. Otherwise, signoff
505 packets may not reach the clients. Affected files are
506 silcd/server.c and silcd/server_util.[ch].
508 * Fixed a bug in version string parsing which could crash
509 the program with specially formatted version string.
510 Bug reported and patch provided by Ville Räsänen. Affected
511 file lib/silcutil/silcutil.c.
513 * Handle the disconnection immediately when DISCONNECT
514 packet is received in server. Affected file silcd/server.c.
516 * Primary router now waits a short time (10 seconds) for
517 backup router connection before accepting any other
518 connection (except local). Affected file silcd/server.c,
521 * Fixed a crash in client libary in NICK_CHANGE notify when
522 NICK_CHANGE arrived for client entry we are resolving
523 currently. Affected file lib/silcclient/client_notify.c.
525 * Call the sconn->callback completion even if error had
526 occurred. Start reconnecting always if connection to
527 primary router fails during backup router protocol.
528 Affected files silcd/server.c and server_backup.c.
530 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Added functions silc_server_send_opers and
533 silc_server_send_opers_notify to send packets stricly
534 to operators. Added macro SILC_SERVER_SEND_OPERS macro
535 to send variable argument notify to operators.
536 Affected files silcd/packet_send.[ch] and silcd/server.h.
538 * Removed UMODE rights checking with UMODE_CHANGE notify.
539 Affected file silcd/packet_receive.c.
541 * Server/router operator now receives notify when network
542 switches to backup router and when it resumes the use of
543 primary router. Affected file silcd/server.c and
544 silcd/server_backup.c.
546 * Fixed the updating of client information after backup
547 resuming protocol is over; update all except local clients
548 to the new primary router. The affected file is
551 * Added support for closing active connections in rehash
552 that were unconfigured by the user. Supports currently
553 closing server and router connections. Affected file
556 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
558 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
560 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
561 is NULL since seems that on some platforms NULL is allowed
562 and on some it's not. Fallback encoding is used instead.
563 Affected file lib/silcutil/silcstrutil.c.
565 * Fixed statistics updating for incoming server connection
566 which could cause problems when re-connecting. Affected
569 * Preliminary backup router support for standalone router
570 added. Affected files in silcd/.
572 * Mark server connections in backup router disabled before
573 and after backup protocol. Affected file is
574 silcd/server_backup.c.
576 * Added support for reconnecting to remote server connection
577 even if the protocol fails, and if the configuration wants
578 us to keep trying to connect anyway.
580 Server connection is not allowed to backup router if
581 backup router does not have connection to primary router yet.
583 Affected file is silcd/server.c.

588 server info. Affected file lib/silcclient/idlist.[ch].
590 * Added check for server entries that are being resolved when
591 notify is received. If being resolved, handle the received
592 notify only after it's resolved so that all notifys are
593 handled in same order as received from the server.
595 Added similar resolver check to channel entries. Every
596 notify that cause resolving of any information that affects
597 channel entry marks the channel entry in waiting state.
598 After whatever resolving is over the waiters are signalled
599 and only then the notifys are handled in the same order
600 as delivered from the server.
602 Affected files are lib/silcclient/idlist.[ch], and
605 * Fixed KILLED notify handling in normal server. Affected
606 file silcd/packet_receive.c.
608 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
609 is locally connected, or was locally connected (but may
610 be detached and connection is not active). Added also

615 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
617 * Don't send or handle TOPIC_SET if topic is already set and
618 is same as being set. Affected files silcd/command.c and
619 silcd/packet_receive.c.
621 * Fixed CMODE change rights checking to work correctly when
622 removing modes by operator. Affected file is

639 to the sender of the notify too, to avoid situation where two
640 notifys are in the network at the same time going to oppsite
641 directions. Affected file silcd/packet_receice.c.
643 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Delete the client from channel even if the cilent->id is
646 NULL. It was possible that client was deleted without
647 removing from channels (theoretically at least). Affected
648 file silcd/server.c and silcd/server_util.c.
650 * Free the client data too when resuming is not successful.
651 Affected file silcd/packet_receive.c.
653 * Merged some code from c0ffee's silc-plugin. Affected files
654 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
656 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
657 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
658 to the primary router connection, the other one returns
659 TRUE if packet must be broadcasted to network.
661 * All notifys that are destined to primary router (to network)
662 are now automatically sent to backup routers even if the
663 router is standalone (and has backup router). Affected files
666 * Added --without-irssi and --without-silcd configuration
667 options for disabling the compilation of these applications.
668 Affected file configure.in.pre and prepare.

694 command reply from router, on normal server. Otherwise
695 joinig +a channels from normal server is not possible.
696 Affected file silcd/command.c.
698 * Fixed a bug in TOPIC_SET notify handling. The notifier
699 may be other than client too, like server or channel.
700 It expected it to always be only client and ignored the
701 notify. Affected file silcd/packet_recieve.c.
703 * Removed some (unnecessary) debug printing from
704 lib/silccore/silcid.c and lib/silccore/silcargument.c.
706 * Do not force CMODE_CHANGE when server is announcing new
709 Router announces stuff only after server reannounces channel
710 after CHANNEL_CHANGE notify.
712 These fixes optimizes the announcing procedure, and perhaps
713 fixes some problems too. Affected file silcd/packet_receive.c.
715 * Fixed SERVER_SIGNOFF sending to local clients. It was
716 totally broken and sent the notify to all local clients,
717 instead of only to those that was on same channel as the
718 signing off clients. Affected file silcd/server_util.c.
720 * Added -D option to server. It can be used to give debug
721 level. The levels are from 0 - 99, and are predefined for
722 smooth server debugging. (see silcd.c for the predefined
723 levels). Affected file silcd/server.c.
725 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

820 * Added error printing of any error that has occurred during
821 any command in client library. Affected file is
822 irssi/src/silc/core/client_ops.c.

1128 * Defined that the nickname hash in Client ID MUST be from
1129 lowercase nickname. This effectively changes nicknames in
1130 SILC to case-insensitive. Updated the protocol specs and
1131 the code. Affected files are lib/silcutil/silcutil.[ch],
1132 silcd/serverid.c, and silcd/idlist.c.

1144 or user mode changes the watcher will be notified of this
1145 change. Added SILC_COMMAND_WATCH command, added new
1146 notify type SILC_NOTIFY_TYPE_WATCH to deliver the watch
1147 notifications. Updated the protocol specs and implemented
1148 this to library, client and server. Protocol TODO #21.

1196 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
1199 that it is used to send error notifys if error occurs during
1200 some SILC packet processing, except commands. The error
1201 types are same as for command reply types. Defined that
1202 if private message is sent to unknown Client ID the error
1203 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
1204 Updated the protocol specs and code. Affected files are
1205 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
1206 lib/silcclient/client_notify.c, silcd/packet_receive.c,
1207 and irssi/src/silc/core/client_ops.c. Renamed the
1208 SilcCommandStatus to SilcStatus.
1210 * Defined the use of extra WHOIS attributes in WHOIS command.
1211 The <Requested Attributes> (defined in a separate document)
1212 can be used to request additional information about user
1213 not returned by standard WHOIS command. Defined that server
1214 can send WHOIS command directly to client. Client provides
1215 the requested attributes to the server. Updated the protocol
1216 specs. Protocol TODO #4. Implementation is not done yet
1217 (Protocol TODO #24).
1219 * Renamed function silc_client_command_status_message to

1244 * Added resolve_cmd_ident field to the SilcClientEntry structure
1245 too so that if the entry is for example being resolved so
1246 another command may attach to the same pending command reply
1247 without requiring to resolve the same entry again. Added
1248 support for adding multiple pending commands for one
1249 command idenfier. Affected files lib/silcclient/command.[ch],
1250 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
1252 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Defined that server receives WHOIS command reply for private
1255 and secret channels too. Updated protocol specs and the
1256 code in server. Affected file silcd/command.c.
1258 * Defined <channel user mode list> argument to WHOIS command
1259 reply for returning user modes on the channels. The

1262 client and server. Affected files are silcd/command_reply.c,
1263 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
1264 and lib/silcclient/command_reply.c.
1266 * Save the channels list in WHOIS command reply in normal server
1267 so that WHOIS always shows joined channels also in normal
1268 server and not just on router. Affected file is
1269 silcd/command_reply.c.
1271 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1280 not provided then the command merely returns the current mode
1281 mask to the client. Updated protocol specs and the server.
1282 Affected file is silcd/command.c.
1284 * Added SILC session detachment/resuming support. It is possible
1285 to detach by closing the network connection and then re-connect
1286 and resume to the old client session. Added DETACHED user
1287 mode that server will set for detached client. Added new
1288 packet RESUME_CLIENT which is used to perform the resuming
1289 process. Added DETACH command. Updated the protocol specs,
1290 core library, client and server. Protocol TODO #22. Very
1291 many affected files around the tree.
1293 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1308 * Added new user modes ANONYMOUS for special anonymous servers
1309 that may set the mode for client, and BLOCK_PRIVMSG which
1310 client may set to block incoming private messages unless the
1311 Private Message Key flag is set (using private keys to protect
1312 private messages). Updated protocol specs and code in client
1313 and server and core library. Protocol TODO #23. Affected
1314 files are lib/silccore/silcmode.h, silcd/server.[ch],

1327 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1329 * Redefined the Status Payload to include now two 8 bit fields,
1330 instead of one 16 bit field. This now makes it possible to
1331 send list of errors. Updated the protocol specs and the code
1332 in core library, client library and server. Protocol TODO #1.
1333 Affected files are lib/silccore/silccommand.[ch],
1334 lib/silcclient/command_reply.[ch], silcd/command.c,
1335 silcd/command_reply.c and silcd/packet_receive.[ch].
1337 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1339 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1340 must be handled by the application and should tell the application
1341 that an error message was already printed, and it should print the
1342 config coords (line, filename, ...). Affected files are
1343 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1345 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the

1364 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1366 * Added STATS command to the protocol after all, to return
1367 various statistical information about the network. It can
1368 be used by clients to retrieve statistical information, and
1369 servers may use it to to fetch cell and network wide
1370 statistics from router. Updated the protocol specs and
1371 implemented it to the server. Protocol TODO #16.
1372 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1377 * The LIST command reply in client libary now adds new channel
1378 entry if the returned channel doesn't exist yet in cache,
1379 and returns the channel entry to the application in the
1380 command_reply client operation. Affected file is
1381 lib/silcclient/command_reply.c.
1383 * Changed the channel message payload's MAC generation to
1384 include the IV in the MAC as well. This way all relevant
1385 parts of the channel message payload are authenticated also
1386 with the channel message MAC (and not only by packet MAC).
1387 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1388 Affected file is lib/silccore/silcchannel.c.
1390 * Fixed the SKE to save the remote version, since the
1391 silc_ske_parse_version mistakenly checked wrong version,
1392 after it replaced the start payload. Affected files are
1393 lib/silcske/silcske.[ch].
1395 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1403 files are lib/silcutil/silcstrutil.[ch].
1405 * Defined that the security property fields in SKE SHOULD be
1406 UTF-8 encoded, defined that version string MUST be US-ASCII
1407 encoded, defined that passphrases sent in connection
1408 authentication protocol MUST be UTF-8 encoded. Implemented
1409 these to the client and server. Defined also that other
1410 passphrases sent in the protocol MUST be UTF-8 encoded.
1411 Affected files are lib/silcske/silcske.c,
1412 lib/silcclient/protocol.c, silcd/protocol.c,
1413 silcd/serverconfig.c, and lib/silccore/silcauth.c.

1416 need the SilcSocketConnection which should not be visible
1417 to application. Affected files are lib/silcclient/client.c
1418 and lib/silcclient/silcclient.h.
1420 * Rewrote the text for Private Message Key Payload in the
1421 protocol specification. Protocol TODO #11.
1423 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1425 * Upgraded the protocol version to 1.1, updated protocol specs
1428 * Added the nickname as new argument to NICK_CHANGE notify and
1429 added it to protocol specs and implemented it to client and
1430 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1431 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1432 lib/silcclient/client_notify.c.

1435 it to protocol specs and implemented it to client and server.
1436 Protocol TODO #13. Affected files are silcd/command.c,
1437 silcd/packet_receive.c, packet_send.[ch],
1438 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1439 The killer's client entry is now returned to application in
1440 the `notify' client operation.
1442 * Fixed the Max Argument fields that had too large value set
1443 in the protocol specs. Protocol TODO #14.
1445 * Added the LEAVE command reply to return the ID of parted
1446 channel. Updated protocol specs and implemented it to the
1447 client and server. Protocol TODO #15. Affected files are
1448 silcd/command.c, lib/silcclient/command_reply.c. The channel
1449 entry is now returned to application in the `command_reply'

1459 file is silcd/command.c.
1461 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1462 generic reply to a generic request (REQUEST flag), and
1463 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1464 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1465 to define the payload for DATA flag. Added the flags to
1466 the implementation. Protocol TODO #9. Affected file is
1467 lib/silccore/silcchannel.h.
1469 Changed the client library to return the message length
1470 to application as well in the channel_message and private_message
1471 client operations. Affected files are
1472 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,

1483 Added new options m and M to CMODE command in Irssi SILC
1484 client to set these modes.
1486 * Deprecated all administrative commands from SILC protocol
1487 since they are highly implementation specific commands.
1488 Updated protocol specs. Moved the old commands in
1489 implementations to private range of command types. Affected
1490 files are silcd/command.c, lib/silcclient/command.c and

1511 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1513 * Some client implementations quit network by doing first LEAVE
1514 and then immediately SIGNOFF (like Bombyx). We now do check
1515 after a short time after LEAVE notify and check whether the
1516 client is still valid after LEAVE, and if not we remove it from
1517 cache. Affected file is lib/silcclient/client_notify.c.
1519 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1521 * Merged version 1.1.4 of zlib. Even if it not currently in use,

1534 totally saved 16 bytes of memory per context after optimization.
1535 Affected files are lib/silccore/silcpacket.[ch].
1537 * Made strict checks for valid SILC IDs. Affected file is
1538 lib/silccore/silcid.c.
1540 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1542 * Changed the object argument for silc_cipher_register,

1544 to const. Affected files are lib/silccrypt/silccipher.[ch],
1545 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1547 * Changed the silc_get_username and silc_get_real_name to
1548 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1550 * Fixed the Irssi SILC Client to use the silc_get_username and
1551 silc_get_real_name insted of glib routines since the glib
1552 routines only corrupt stack. Fixes the Irssi SILC to work in
1553 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1555 * Fixed the Irssi to not use g_get_home_dir since it crashes
1556 or returns garbage on cygwin and corrupts stack. Added function
1557 get_home_dir to Irssi routines. Affected files are
1558 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1560 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Made some structure optimizations. SFTP memory FS MemFSEntry
1563 entry structure. Optimized SilcTask structure. Optimized
1564 SilcPacketContext structure.
1566 Affected files lib/silcsftp/sftp_fs_memory.c,
1567 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1569 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1571 * And yet again reverted back the config thing since Johnny
1572 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1575 * Fixed memory leaks from config object. Affected files are
1576 silcd/serverconfig.[ch].
1578 * Added support for adding new connections to the server in rehash.
1579 After rehash they take effect.
1581 Added support for changing the maximum allowed connections in
1582 rehash. The number can grow but going smaller is not supported.
1584 Added function silc_server_num_sockets_by_remote to the
1585 silcd/server_util.[ch].
1587 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1589 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1591 * Added preliminary checking during config parsing for a valid
1592 public/private key and removed further checks in the code.
1593 Affected files are silcd/serverconfig.[ch], server.c.
1595 * Moved functions silc_server_drop() and silc_server_daemonise()
1596 from server.c to silcd.c since they are stricly related to
1597 the application activity.
1599 * Reverted a small part of the automatic ref/unref since
1600 it caused a double unref in some situations. Affected
1601 files are silcd/silcd.[ch], server.c, serverconfig.c.
1603 * Added some .cvsignore files in the lib directory.
1605 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * Fixed silc_net_gethostbyaddr to correctly resolve by
1608 address. Affected file lib/silcutil/silcnet.c.
1610 * Fixed the notify relaying to client. The HMAC to be used
1611 with relayed packets ws wrong and caused decryption failure
1612 at the client end. Affected file is silcd/packet_receive.c.
1614 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1616 * Created new branch silc_protocol_1_0_branch.
1618 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1620 * Changed the silc_server_config_* routines to be SilcServer
1621 independent. They are now officially application specific code
1622 and not part of generic server implementation. Affected files
1623 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1625 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1627 * Added automatic referencing of config context in the
1628 silc_server_config_alloc, and automatic unreferencing in the
1629 silc_server_config_destroy. Affected files are
1630 silcd/serverconfig.[ch], silcd/silcd.c.
1632 * Fixed the silc_log_quick handling in the logging routines.
1633 It didn't log quickly when it was TRUE. Affected file is
1634 lib/silcutil/silclog.c. Also the flush delay was set even
1635 if it was 0 in config file. Affected file is
1636 silcd/serverconfig.c.
1638 * Added support for changing key pair of the server in rehash.
1639 Affected file silcd/server.c.
1641 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1644 too early, before getting the channel entry. Affected file
1645 is silcd/packet_receive.c.
1647 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1649 * Added functions silc_server_config_[ref/unref], these are used
1650 to prevent that the config object is destroyed.
1652 No longer directly affect global variables silc_log_quick and
1653 silc_log_delay, they are first cached inside the config object
1654 and then applied with silc_server_config_setlogfiles().
1656 silc_server_config_set_defaults() is now internal to
1657 serverconfig.c, there are no reasons to show this internal stuff
1660 Affected files are silcd/serverconfig.[ch].
1662 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1663 fprintf's to stderr, since some code may be executed again after
1664 the server went into the background. Affected files are
1667 * Added rehash support. Added function silc_server_rehash() that
1668 will perform all the basic tasks of the rehashing procedure.
1670 * Added command line option `-x, --hexdump'. This will enable the
1671 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1672 The option `--hexdump' implies `--debug'.
1674 * Fixed a bad bug in the logging APIs (silcutil library) where
1675 the application would crash after calling silc_log_reset_all().
1677 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Fixed the KICKED notify handling in client library to
1680 correctly remove the channel and all entries from the
1681 channel when I was kicked. This bug crashed the client.
1683 Fixed yet another but in KICKED notify handling to remove
1684 the kicked client correctly from the channel.
1686 Affected file is lib/silcclient/client_notify.c.
1688 * Fixed a minor bug in looking up correct client entry
1689 in KICKED notify in server. Affected file is
1690 silcd/packet_receive.c.
1692 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1693 sources correctly to distribution. Fixes --with-gmp option.
1695 * Removed the manual rehashing from ID Cache, and changed it
1696 to use the SILC Hash Table's auto rehash feature. Affected
1697 file is lib/silccore/silcidcache.c.
1699 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed a bug in the silc_client_nickname_format function that
1702 handles the multiple same nickname formatting. Two clients
1703 with same nickname caused problems after the first one left
1704 and rejoined. It didn't format the nickname correctly.
1705 Affected file is lib/silcclient/idlist.c.
1707 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1709 * Don't change the topic if olod topic is same as new one.
1710 Affected file is silcd/packet_receive.c.
1712 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1714 * Added cross-reference support to the SILC Documentation
1715 generator. All types across all HTML files are now cross-
1716 referenced. Affected files util/robodoc/generator.c and
1717 scripts/silcdoc/silcdoc.
1719 * Added file lib/silcutil/silctypes.h to include all the
1720 arithmetic type definitions and some macros. Removed
1721 includes/bitmove.h and moved macros to silctypes.h.
1723 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1725 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1727 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1729 * Added `type' argument to silc_id_payload_parse_id function which
1730 now returns the type of the ID to the sent pointer. Affected
1731 file is lib/silccore/silcid.[ch].
1733 * Added check for CMODE_CHANGE notify type that mode change is
1734 allowed by the sender. Affected file silcd/packet_receive.c.
1736 * Added check for CUMODE_CHANGE notify type that mode change is
1737 allowed by the sender. Affected file silcd/packet_receive.c.
1738 Added the ID type as CUMODE_CHANGE notify type as argument
1739 to the `notify' client operation. Affected files are
1740 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1742 * Added function silc_client_add_server to the client library.
1743 Added support for resolving also channel and server info when
1744 received unknown entity in notify packet. Affected files are
1745 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1747 * Added function silc_command_get_status to return the command
1748 status from the command reply's argument payload. Affected files
1749 are lib/silccore/silccommand.[ch].
1751 * Added check for KICKED notify type that the kicking is
1752 allowed by the client. Affected file silcd/packet_receive.c.
1754 * Created function silc_get_input which can be used to get input
1755 (echo on or off) from user on command line. Affected files are
1756 lib/silcutil/silcutil.[ch].
1758 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1760 * Optimized silc_server_packet_relay_to_channel function.
1761 Added new function silc_channel_message_payload_encrypt which
1762 can be called directly if channel message payload needs to
1763 be encrypted and is already encoded (no need to call _encode
1764 function). Packet relaying is now done by router without any
1765 extra memory allocations. Affected files are
1766 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1767 silcd/packet_send.c.
1769 * Fixed the INVITE notify handling. It took wrong arguments
1770 as invite list and invite delete. Affected file is
1771 silcd/packet_receive.c.
1773 * Added check for TOPIC_SET notify type that the topic change is
1774 allowed by the client. Affected file silcd/packet_receive.c.
1776 * Added check for INVITE notify type that inviting is allowed by
1777 the client. Affected file silcd/packet_receive.c.
1779 * Changed the silc_server_client_on_channel to return the
1780 SilcChannelClientEntry as well. Moved the function
1781 silc_server_check_cmode_rights to server_util.[ch].
1782 Affected files are silcd/server_util.[ch], silcd/command.c.
1784 * Added function silc_server_check_umode_rights to check whether
1785 changing client's user mode is allowed. Added check for
1786 UMODE_CHANGE notify type that the umode change is allowed
1787 by the client. Affected files are silcd/server_util.[ch],
1788 silcd/packet_receive.c and silcd/command.c.
1790 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1793 ID length. It ignored that ID can be IPv6 based as well.
1794 Affected file lib/silccore/silcpacket.h.
1796 * Fixed the silc_id_id2str and silc_id_str2id to take the
1797 IPv6 address offset's into consideration. Affecte file is
1798 lib/silccore/silcid.c.
1800 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1802 * Fixed the internal Unix scheduler functions to check for
1803 NULL context they may receive. The affected file is
1804 lib/silcutil/unix/silcunixschedule.c.
1806 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1808 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1809 can specify different directory with --home command line
1810 parameter. Affected files irssi/src/silc/core/client_ops.c,
1813 * SILC-specific commands aren't now executed if the active server
1814 isn't of SILC-type, so there won't be problems with having
1815 IRC and SILC protocol support in same client. Affected files
1816 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1819 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Improved the signal support in SILC Schedule. Added new
1822 function silc_schedule_signal_call which is used by application
1823 to mark a signal to be called. It is now safe to perform
1824 any kind of tasks in signal callbacks since it is guaranteed
1825 that the application specified signal callback is called
1826 after the signal is over. Affected files are
1827 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1829 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1831 * Added `name' field to SilcChannelPrivateKey to represent
1832 application given name for the key. Moved also the context from
1833 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1834 Added the `name' argument also to the function
1835 silc_client_add_channel_private_key.
1837 Added function silc_client_current_channel_private_key to set the
1838 current channel private key in use.
1840 Added "change" command to KEY command which can be used to change
1841 the current channel private key. Bound the command also to
1842 alt+K (Alt+Shift+k).
1844 Also affected files lib/silcclient/client_channel.c,
1845 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1847 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Added silc_rng_get_byte_fast function in to the
1850 lib/silccrypt/silcrng.[ch].
1852 * Changed the interface of silc_packet_assemble and the
1853 silc_packet_send_prepare. If silc_packet_assmble is now
1854 called the application does not call silc_packet_send_prepare
1855 because the library will call it automatically. These
1856 interfaces now also return a reference to the outgoing buffer
1857 which includes the assembled packet, which the application can
1858 use to encrypt the packet.
1860 Affected files are lib/silccore/silcpacket.[ch],
1861 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1862 silcd/packet_send.c, server_backup.c and packet_receive.c.
1864 * Fixed a packet sending bug on very high load, where outgoing
1865 packet queue wasn't handled correctly and packets got corrupted.
1866 Affected files are lib/silcutil/*/silc*sockconn.c,
1867 lib/silcclient/client.c and silcd/server.c.
1869 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1871 * Added macro SILC_PACKET_DATALEN which can be used during
1872 packet assembling to check whether the data to be added to
1873 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1874 len is truncated until it fits it.
1876 Added checks for maximum length of channel message payload and
1877 private message payload also.
1879 Added checks for maximum packet length in server and in
1882 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1883 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1884 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1885 lib/silcclient/client_prvmsg.c.
1887 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1889 * Added silc_server_packet_queue_purge call to the
1890 silc_server_disconnect_remote to assure that all data in the
1891 queue before disconnecting is sent to the network. Affected
1892 file silcd/server.c.
1894 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1896 * Added the deleting of server's own ID cache entry to the
1897 silc_server_free function. Free also everything else that
1898 has been allocated in silc_server_init. The affected file
1901 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1903 * Added functions silc_parse_version_string, silc_version_to_num,
1904 and silc_ske_parse_version to parse SILC protocol style version
1905 strings. Affected files lib/silcutil/silcutil.[ch] and
1906 lib/silcske/silcske.[ch].
1908 * Added new configuration params: version_protocol, version_software
1909 and version_software_vendor to specify what version the remote
1910 host must at least be to be able to connect to server. The vendor
1911 string can be regex matched too. Added new function
1912 silc_server_connection_allowed to check maximum number of allowed
1913 connections, and allowed versions for incoming connections.
1914 Affected files are silcd/server.c, server_util.[ch] and
1917 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1919 * Added preliminary support for signals in scheduler. The
1920 signals we care about are now blocked always when the scheduler
1921 is locked. This way we can synchronise the use of signal with
1922 scheduler. It is guaranteed that when signal occurs the scheduler
1923 is not locked, and thus new tasks can be safely added to the
1926 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1927 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1928 Added new platform specific routines
1929 silc_schedule_internal_signals_[un]block and
1930 silc_schedule_internal_signal_[un]register.
1932 Added new functions to SILC Schedule API:
1933 silc_schedule_signal_[un]register. Each signal that application
1934 is going to use should be registered to the scheduler.
1936 Affected files are lib/silcutil/silcschedule.[ch],
1937 lib/silcutil/*/silc*schedule.c.
1939 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1941 * Check for unauthenticated client and server in the
1942 silc_server_new_client and silc_server_new_server functions.
1943 Affected file silcd/packet_receive.c.
1945 * Added function silc_string_is_ascii to check whether given
1946 string is 7-bit ASCII string. Affected files are
1947 lib/silcutil/silcutil.[ch].
1949 * Added function silc_id_is_valid_server_id into the
1950 silcd/serverid.c and added checking for valid Server ID's in
1951 silc_server_new_server. The Server ID must always be based
1952 on the server's public IP address.
1954 * Added logging of DISCONNECT packet message in the server.
1955 Affected file silcd/server.c.
1957 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1959 * Changed all library interfaces that use Global RNG to also
1960 accept SilcRng as argument. Affected files are
1961 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1962 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1963 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1964 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1965 lib/silccrypt/rsa.c.
1967 * Added function silc_pkcs_generate_key to the
1968 lib/silccrypt/silcpkcs.[ch] for applications so that they
1969 don't need to do pkcs->pkcs->init calls anymore.
1971 * Remove SilcSocketConnection from the SFTP API since it really
1972 wasn't needed there. The application has the information
1973 saved in its contexts anyway and the SFTP layer doesn't need
1974 know about it. Affected files lib/silcsft/silcsftp.h and
1975 lib/silcsftp/sftp_[server/client].c.
1977 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1978 The SilcSimContext is not SilcSim.
1980 * Fixed possible buffer overflows in silc_id_render in the
1981 lib/silcutil/silcutil.c.
1983 * On EPOC the global crypto module lists are not used at all
1984 in the crypto library. Added support for using the constant
1985 algorithm list on EPOC. Affected files are
1986 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1989 * Fixed the handling of third parameter of KICKED notify, since
1990 it was mistakenly updated to SILC Protocol 1.0 even though it
1991 is to be included in 1.1. Since it is not in 1.0 it is not
1992 mandatory, and this fix now handles it only if it is provided,
1993 and it is not error if it is not provided. Affected file
1994 lib/silcclient/client_notify.c.
1996 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1998 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1999 client. Affected file irssi/src/silc/core/client_ops.c.
2001 * Merged with Irssi 0.8.4 from irssi.org CVS.
2003 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2005 * Check for valid socket connection in client entries before
2006 sending any messages. Fixes a crash, but doesn't fix some
2007 other underlaying bug that is lurking there. Affected
2008 file silcd/packet_send.c.
2010 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2012 * $usermode, $cumode and $cumode_space expandos shouldn't do
2013 anything with non-SILC server records. Affected file
2014 irssi/src/silc/core/silc-expandos.c
2016 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2018 * Fixed the silc_net_check_[host/local]_by_sock to support
2019 IPv6 bound sockets as well. Now they can return IPv6 addresses
2020 as well. Affected file lib/silcutil/silcnet.c.
2022 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2023 Affected lib/silcutil/unix/silcunixnet.c.
2025 * Fixed ID rendering (at least on some platforms, not NetBSD)
2026 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2028 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2030 * Added silc_hash_public_key and silc_hash_public_key_compare
2031 functions to be used with SilcHashTable. They can be used to
2032 hash public keys and compare public keys in hash table. Affected
2033 file lib/silcutil/silcutil.[ch].
2035 * Added support for specifying multiple public keys for Client
2036 connection section in server configuration file. This makes it
2037 possible to accept multiple public keys from same host, or to
2038 make a section that accepts any incoming host, and have the
2039 accepted public keys listed in the section.
2041 Added functions silc_sever_[find/get]_public_key, added the
2042 support for this actually to all connection sections but only
2043 the Client section is currently allowed to specify multiple
2046 Affected files are silcd/server.c, server_internal.h,
2047 command.c, protocol.c, server_util.[ch], packet_receive.c.
2049 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2051 * Merged Irssi 0.8.2 from irssi.org CVS.
2053 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2055 * If silc_debug is TRUE, also output standard logging messages
2056 to stderr with the debug output.
2058 Made silc_log_reset_all() flushing all channels before returning.
2059 Also fixed some documentation typos.
2061 Affected files are lib/silcutil/silclog.[ch].
2063 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2065 * Fixed the server to check correctly the amount of connections
2066 from single host, by checking also the type of the connection.
2067 Fixed also the comparison of number of connections and number
2068 of allowed connections. Affected files are silcd/server.c,
2071 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2073 * Fixed the USERS command reply to save the user's mode on the
2074 channel as well. Fixed JOIN command reply to check whether a
2075 client is on channel already and not join it twice. Affected
2076 file lib/silcclient/command_reply.c.
2078 * Added new file silc-expandos.c into irssi/silc/core/ to return
2079 various stuff for various signal for the statusbar etc. updating.
2080 Now Irssi SILC client prints channel user modes etc. on the

2150 application does not need to define them. Affected file
2151 includes/silcincludes.h.
2153 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2154 old name went against naming convention. Applications now
2155 include "silcclient.h" instead of "clientlibincludes.h".
2156 Removed includes/clientlibincludes.h, it is redundant now.
2158 * Renamed includes/version.h to silcversion.h.
2160 * Added really preliminary support for OS/2 into the util

2196 * Added `user_count' to the SilcChannelEntry which now tells the
2197 number of users on the channel. The user count is now saved
2198 in normal server of global channels as well. Affected files
2199 silcd/server.c, idlist.h, packet_receive.c and command.c.
2201 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2202 include file utility functions.

2218 the SKE interface a bit.
2220 * Fixed padding problem in PKCS#1. The padding was not actually
2221 random since the random number generator was used incorrectly.
2222 This security bug affects only when encrypting with PKCS#1, and
2223 it is not currently used at all in SILC. SILC only use signing
2224 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2284 is now done in silc_core_init() which also fixes autoconnecting
2287 Affected files irssi/src/silc/core/silc-core.c,
2288 irssi/src/fe-text/silc.c.
2290 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2292 * Added new configuration options and blocks:
2293 keepalive_secs, reconnect_count, reconnect_interval,
2294 reconnect_interval_max, reconnect_keep_trying and
2295 require_reverser_lookup. Added ConnectionParam block, and
2296 implemented the connection parameters when connecting as
2297 initiator and when accepting connections as responder.

2309 the connection configuration object from the SilcServerConnection
2310 object instead of finding it during the connecting phase.
2311 Added the configuration object to SilcServerConnection struct.
2312 Affected files silcd/server_internal.h, server.c.
2314 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2316 * Add the client on channel after it was resolved at the
2317 channel message receiving, and it was not already on the
2318 channel. Affected file lib/silcclient/client_channel.c.
2320 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2336 authentication to be set at the same time.
2338 Added `prefer_passphrase_auth' setting in config file which
2339 can be used to set to prefer passwd auth if both passwd and
2340 public key is set. If not set, public key is preferred.
2341 This has effect only when being initiator (responder will try
2344 Added support for authentication with passphrase and public key
2345 at the same time. The passphrase is tried first always since
2346 it is faster to check.
2348 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2350 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2396 * Fixed the file transfer's key agreement payload to include
2397 zero port also if the hostname is NULL because it could not
2400 Call file transfer monitor callback now also if error occurs
2401 during key agreement protocol.
2403 Changed the silc_client_file_send interface to return the
2404 SilcClientFileError instead of session id. The session ID
2405 is returned into pointer provided as argument.
2407 Check that the file exists locally before sending the
2408 file transfer request at all.
2410 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2412 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

2417 is changed and +k mode is set in the channel. Affected file
2418 irssi/src/silc/core/silc-channels.c.
2420 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2421 SILC_LOG_WARNING to give out Warning and not Error. Affected
2422 file lib/silcutil/silclog.c.
2424 * Fixed the channel message payload decryption in the function
2425 silc_channel_message_payload_decrypt to not modify the original
2426 buffer before it is verified that the message decrypted
2427 correctly. Otherwise, next time it is called with correct
2428 channel key it won't encrypt since the payload is corrupted.
2429 Affected file lib/silccore/silcchannel.c.
2431 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2443 * Fixed a bug in hash table internal routine for traversing
2444 the table with foreach callback. The current entry may
2445 become invalid in the callback but it was referenced after
2446 the callback returned.
2448 Do not allow auto rehashing of hash table during the
2449 silc_hash_table_foreach operation, for same reasons as it is
2450 not allowed for SilcHashTableList. Affected files are
2451 lib/silcutil/silchashtable.[ch].
2453 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2474 users list to SilcHashTable. The affected files are
2475 lib/silcclient/idlist.[ch].
2477 * Fixed a bug in hash table tarversing. While the hash table
2478 is traversed with SilcHashTableList the table must not be
2479 rehashed. It is now guaranteed that auto rehashable tables
2480 are not rehashed while tarversing the list. Also defined that
2481 silc_hash_table_rehash must not be called while tarversing
2482 the table. Added function silc_hash_table_list_reset that must
2483 be called after the tarversing is over. The affected files are
2484 lib/silcutil/silchashtable.[ch].
2486 * Changed all hash table traversing to call the new
2487 silc_hash_table_list_reset in server and in client library.
2489 * Added function silc_client_on_channel to return the
2490 SilcChannelUser entry if the specified client entry is joined
2491 on the specified channel. This is exported to application as
2492 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2497 server. The notify for mode change must be sent always and
2498 not only if !cmd->pending. Affected file silcd/command.c.
2500 * Fixed the WHOWAS command's reply sending to support the
2501 lists correctly. Affected file silcd/command.c.
2503 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2505 * When sending JOIN command to router for processing the
2506 sender's old command identifier was not saved back to the
2507 sender's command context, fixed now. The affected file is
2510 * Create the key in JOIN command of the router did not return
2511 the channel key, added check for this. Affected file is
2514 * Fixed a channel ID update bug in JOIN command reply. Do
2515 not directly upgrade the ID but call the function
2516 silc_idlist_replace_channel_id if the ID was changed.
2517 Affected file silcd/command_reply.c.
2519 * Fixed memory leaks from command calling if it would fail.
2520 Affected file silcd/command.c.

2547 functions. Affected file silcd/server.c.
2549 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2550 which ID was changed. This way the router will send the
2551 user list for the channel again, and server won't be in
2552 desync in some rare circumstances. Affected file is
2553 silcd/packet_receive.c.
2555 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2604 * Fixed the NICK command to always give the unformatted
2605 nickname to the one giving the NICK command. If unformatted
2606 nickname is cached already it will be formatted and the
2607 local entry will always get the unformatted nickname.
2608 Affected file lib/silcclient/idlist.c.
2610 * Fixed some double frees from client library commands.
2611 Affected file is lib/silcclient/command.c.
2613 * Fixed CUMODE command in server to assure that no one can
2614 change founder's mode than the founder itself, there was a
2615 little bug. Affected file silcd/command.c.
2617 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2619 * Removed the SilcClientCommandDestructor from the client
2620 libary, it is not needed anymore. Affected files are
2621 lib/silcclient/silcapi.h, command[_reply].[ch],
2622 client_notify, idlist.c.
2624 * Fixed GETKEY command to first resolve client, and then
2625 resolve the server only if the client was not found, instead
2626 of resolving both at the same time. Affected file is
2627 lib/silcclient/command.c.
2629 * Added silc_client_start_key_exchange_cb and lookup the
2630 remote hostname and IP address before starting the key
2631 exchange with server. The affected file is
2632 lib/silcclient/client.c.
2634 * The server's public key is now saved using the IP address
2635 of the server and not the servername for the filename.
2636 The hostname public key filename is checked as an fall back
2637 method if the IP address based filename is not found.
2639 Fixed the GETKEY command to save the fetched server key
2640 in correct filename.
2642 Print the remote server's hostname now when new key is
2643 received during connection process. Affected file is
2644 irssi/src/silc/core/client_ops.c.
2646 * Return always our own public key to the client if it asks
2647 for it with GETKEY command. Affected file silcd/command.c.
2649 * Removed the use_auto_addr variable from default config
2650 file since it was in wrong section. Affected file is
2653 * Fixed TOPIC_CHANGE notification to not route it when it
2654 was sent using silc_server_send_notify_to_channel function.
2655 Affected file silcd/command.c.
2657 * Fixed silc_server_send_notify_kicked to send the kicker's
2658 Client ID also, it was missing. Affected files are
2659 silcd/command.c, silcd/packet_send.[ch].
2661 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2663 * Do not save client history information in SERVER_SIGNOFF.
2664 Fixes the bug in normal server that it does not detect
2665 the client becoming valid after the server becomes back
2666 online. Affected file silcd/server_util.c.
2668 * Added `sock_error' field into the SilcSocketConnection
2669 context. When error occurs during socket operation (read
2670 or write) the error is saved. Added also new function
2671 silc_socket_get_error to return human readable socket error
2672 message. Affected files are lib/silcutil/silcsockconn.[ch],
2673 lib/silcutil/unix/silcunixsockconn.c, and
2674 lib/silcutil/win32/silcwin32sockconn.c.
2676 * The server now prints the socket error message in the
2677 signoff for client. Affected file silcd/server.c.
2679 * Fixed the `created' channel information sending from router
2680 to server in JOIN command. Checks now whether the channel
2681 really was created or not and set it according that.
2683 Fixed the JOIN command to use the client entry's current
2684 ID during the joining procedure instead of the one it sent
2685 in the command (it is checked though), since it can change
2686 between the packet processing and command processing, and
2687 would just case unnecessary pain in the client end. Affected
2688 file silcd/command.c.
2690 * Fixed a channel key payload sending to use correct channel
2691 ID when the server was forced to change the channel's ID by
2692 router. Router sent the key payload with the old Channel ID.
2693 Affected file silcd/packet_receive.c.
2695 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2697 * Call silc_server_save_channel_key only if the key payload
2698 was provided in the JOIN command's command reply. Affected
2699 file silcd/command_reply.c.
2701 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2703 * Fixed silc_mp_sizeinbase to return the value correctly with
2704 MPI. Affected file lib/silcmath/mp_mpi.c.
2706 * Fixed the stop_server signal to correctly stop the scheduler
2707 and gracefully stop the server when SIGTERM or SIGINT signals
2708 are received. Affected file silcd/silcd.c.
2710 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2712 * Simple handling of TERM and HUP signals. Also added some log
2713 flushing call around. Affected file is
2716 * Fixed small bugs in silclog.c. Now buffering output will take
2717 effect after 10 seconds since startup: This will ensure that
2718 no important startup messages are lost. Also output redirection
2719 will preserve original format ([Date] [Type] message).
2720 Affected file is lib/silcutil/silclog.c.
2722 * Added two options to the config file, in the logging section:
2723 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2724 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2726 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2728 * Do not print the warning about log files not being initialized
2729 more than once to avoid excess logging. Affected file is
2730 lib/silcutil/silclog.c.
2732 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2733 the SIM copying in make install in Makefile.am.pre.
2735 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2737 * Rewritten silclog APIs. Globally interesting changes follows:
2738 silc_log_set_files() changed to silc_log_set_file().
2739 silc_log_set_callbacks() changed to silc_log_set_callback().
2740 ROBOdoc documented silclog header file.
2741 SilcLogCb now returns bool to wether inihibit the default
2742 handler or not (to keep the old behaviour return always TRUE).
2743 The new APIs should also fix the problem of the
2744 silcd_error.log file that was written in the current directory.
2747 Log files streams will remain opened after silc_log_set_file()
2748 call, means less CPU usage notably on high traffic servers.
2749 File streams are now full buffered, and flushed to the disk
2750 every 5 minutes, lesses HD activity and CPU usage.
2751 Messages can be redirected, allowing admins to configure
2752 one single logfile for all server messages.
2753 the silc_log_quick global variable to activate fast-logging.
2754 Affected files lib/silcutil/silclog.[ch]
2756 * Changed some code to conform new silclog APIs. Affected
2757 files are doc/example_silcd.conf.in, silcd/server.c
2758 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2761 * Fixed a memory leak that could occur in some situations.
2762 Affected file silcd/serverconfig.c.
2764 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2766 * Added the silc_client_del_client to remove the client from
2767 all channels as well. Affected file lib/silcclient/idlist.c.
2769 * Fixed the client library to correctly remove the client
2770 from all channels when the client entry is being destroyed.
2771 Affected file lib/silcclient/client_notify.c, command.c.
2773 * Added auto-nicking support to the client library. If the
2774 applicatio now sets client->nickname it will be sent to the
2775 server after connecting by the library. This way for example
2776 SILCNICK (or IRCNICK) environment variables will have effect
2777 and always change the nickname automatically to whatever
2778 it is wanted. Affected file lib/silcclient/client.[ch].
2780 * Renamed silc_server_command_bad_chars to the
2781 silc_server_name_bad_chars and moved it to the
2782 silcd/server_util.[ch]. Added also new function
2783 silc_server_name_modify_bad to return nickname that
2784 includes bad characters as new nickname without those
2785 bad characters. This check and modify is now used in
2786 silc_server_new_client when the username is initially set
2787 as nickname, so it must be checked to be valid nickname.
2788 Affected file silcd/packet_receive.c.
2790 * The nickname length is now taken from the packet for real
2791 and not trusted to strlen() since it clearly can return
2792 wrong length for nickname including bad characters. This
2793 also applies to channel names. Affected file silcd/command.c.
2795 * Removed the lib/silcsilm/modules directory. Modules are now
2796 compiled into the lib/silcsim. Fixed the copying of the
2797 modules to follow symbolic links in Makefile.am.pre.
2799 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2801 * Fixed silc_string_regexify list creation. Fixes bugs with
2802 BAN and INVITE commands in server. The affected file is
2803 lib/silcutil/unix/silcunixutil.c.
2805 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Removed the command destructor entirely from the server's
2808 command and command reply routines. It is not needed, and
2809 its usage was buggy and caused crashes. Affected files are
2810 silcd/command[_reply].[ch].
2812 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Cancel protocol and NULL sock->protocol if timeout
2815 occurred during protocol. Affected file silcd/server.c.
2817 * Cancel protocol timeouts always before calling the final
2818 callback, to assure that after final callback is called
2819 no other state will be called for the protocol anymore.
2820 Affected file silcd/protocol.c.
2822 * Print error log if incoming connection configuration could
2823 not be found. Affected file silcd/server.c.
2825 * Fixed JOIN command to correctly save the founder mode
2826 to the client on normal SILC server, when the channel
2827 was created by the router. Affected file silcd/command.c.
2829 * Fixed LIST command (hopefully) to send correct reply
2830 packets. Affected file silcd/command.c.
2832 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * The silc_packet_receive_process now returns FALSE if the
2835 read data was invalid packet, and TRUE if it was ok.
2837 The server now checks that if unauthenticated connection
2838 sends data and its processing fails the server will close
2839 the connection since it could be a malicious flooder.
2841 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2843 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Make sure the warning about error opening a log file is
2846 printed only once and not everytime it fails (produces
2847 too much useless log). Affected file lib/silcutil/silclog.c.
2849 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2851 * Made the silc_server_daemonise() function more readable.
2852 Affected file silcd/server.c.
2854 * Pid file is now optional, the user may comment it out from
2855 the config file. Removed define SILC_SERVER_PID_FILE, we
2856 don't need a default any longer. Affected file
2857 configure.in.pre, lib/Makefile.am.pre.
2859 * Make some use of the pid file. The server now dies at startup
2860 if it detects a valid pid file on his path. The server would
2861 die anyway in this circumstance, because of the bind() failure.
2862 Affected file silcd/silcd.c.
2864 * No longer compiling lib/dotconf.
2866 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Fixed JOIN command parsing not to crash. Affected file
2869 lib/silcclient/command.c.
2871 * Fied the NICK_CHANGE notify to add the new client entry
2872 even it is resolved. This removes an <[unknown]> nick
2873 thingy bug in the client. Affected file is
2874 lib/silcclient/client_notify.c.
2876 * Do not try to allocate 0 bytes (efence does not like it)
2877 in lib/silccore/silccomand.c when encoding payload.
2879 * Do not take IRCNICK as nickname in Irssi SILC client since
2880 it is not possible to set nickname before hand connecting
2881 the server (TODO has an entry about adding auto-nicking
2884 * Changed the silc_server_command_pending to check whether
2885 there already exists an pending entry with the specified
2886 command, command identifier and pending callback. This is
2887 to fix IDENTIFY and WHOIS related crashes that may register
2888 multiple pending commands with same identifier. Affected
2889 file silcd/command.c.
2891 * Fixed the server to reconnect to the router even if it
2892 was already reconnecting and EOF was received. This to
2893 fix a possibility that the server wouldn't ever try to
2894 auto-reconnect to the router. Affected file silcd/server.c.
2896 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Fixed the server's password authentication to use the
2899 length of the locally saved password, and not the one
2900 sent in the packet. Affected file silcd/protocol.c.
2902 * Fixed same password authentication problem in the
2903 Authentication Payload handling routines in
2904 lib/silccore/silcauth.c.
2906 * Yet another password authentication problem fixed with
2907 channel password handling in silcd/command.c.
2909 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * If first character of string in silc_parse_userfqdn is '@'
2912 then do not parse it. Affected file is
2913 lib/silcutil/silcutil.c.
2915 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Fixed minor bug in IDENTIFY command reply sending, which
2918 caused various weird problems during JOIN when it was
2919 resolving names for users. Affected file silcd/command.c.
2921 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Fixed the IDENTIFY command reply sending to chech better valid
2924 clients. It was possible to send incomplete list of replies.
2925 Affected file silcd/command.c.
2927 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Added silc_client_command[s]_[un]register functions now to
2930 dynamically register the commands in client library. Removed
2931 the static table of commands. This allows the client library
2932 to call commands without causing the application to know about
2933 what commands library has called.
2935 Removed the INFO command reply kludge to detect when the command
2936 was called by library. Now library use its own command reply
2937 function for INFO command.
2939 Added function silc_client_command_call to call a command.
2940 Application can use it to call command, not access the structure
2943 Now all commands that are sent by the client library (not
2944 explicitly sent by application) use own command reply functions.
2946 Affected files around lib/silcclient/ and in
2947 irssi/src/silc/core/.
2949 * Fixed the WHOIS command reply sending to chech better valid
2950 clients. It was possible to send incomplete list of replies.
2952 Fixed the WHOIS and IDENTIFY to send the request to router
2953 if normal server did not do it and did not find any results.
2955 Affected file silcd/command.c.
2957 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Moved the internal data from SilcClient context into its
2960 own file, not accesible to application. Affected files
2961 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2962 and other files in client library.
2964 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Added doc/examples installation target in Makefile.am.pre.
2969 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2972 commands the found client entry will be removed from the
2973 cache, after notifying application about the error. Affected
2974 file lib/silcclient/command_reply.c.
2976 * Changed the /MSG to check for exact nickname user gave, and
2977 not let `nick' match `nick@host' if it is only one found. Now,
2978 user must type the exact nickname (like nick@host2) even if
2979 there are no more than one same nicks found. This is to avoid
2980 a possibility of sending nickname to wrong nickname since
2981 `nick' could match `nick@host'. Affected file is
2982 irssi/src/core/silc-servers.c.
2984 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Do not print "you are now server operator" or similar when
2987 giving /away command. Affected files are
2988 irssi/src/silc/core/client_ops.c, silc-servers.h.
2990 * Made the silc_server_command_pending_error_check to send
2991 the same command reply payload it received back to the
2992 original sender of the command. This way all arguments
2993 that was received by the server will be received by the
2994 client too. Affected file silcd/command.c.
2996 * Added the silc_idcache_add to return the created cache entry
2997 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2999 * Add global clients to expire if they are not on any channel.
3000 This is because normal server will never know if they signoff
3001 if they are not on any channel. The cache expiry will take
3002 case of these entries. This is done by normal servers only.
3003 The affected files are silcd/command_reply.c,
3004 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3006 * If server receives invalid ID notification for WHOIS or
3007 IDENTIFY and the ID exists in the lists, it is removed.
3008 Affected file silcd/command_reply.c.
3010 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3011 in client then client entry that it matches is searched and
3012 the nickname is printed on the screen for user. Affected
3013 file irssi/src/silc/core/client_ops.c.
3015 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Use cache entry expire time in the LIST command reply to
3018 purge old entries from the cache after the LIST command
3019 reply has been received. This way we don't have non-existent
3020 entries in the cache for too long. Affected file is
3021 silcd/command_reply.c.
3023 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * If we are normal server, and we've not resolved client info
3026 in WHOIS or IDENTIFY from router, and it is global client,
3027 we'll check whether it is on some channel. If it is not
3028 then we cannot be sure about its validity and will resolve it
3029 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3030 file silcd/command.c.
3032 * Search channel by name (if possible) rather than by ID
3033 in IDENTIFY command's command reply. Affected file is
3034 silcd/command_reply.c.
3036 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3039 Updated specs and implemented it. Affected file silcd/command.c,
3040 silcd/packet_send.c and silcd/packet_receive.c.
3042 * Implemented the <founder auth> payload handling in the JOIN
3043 command. If provided all conditions for channel joining
3044 except requirement to provide correct passphrase can be
3045 overrided by the channel founder. Updated the protocol specs.
3046 Affected file silcd/command.c.
3048 Added support for founder auth in JOIN command in client
3049 library. Fixed the parsing of the JOIN command now to support
3050 all options as they should be. The affected file is
3051 lib/silcclient/command.c.
3053 * Optimized the WHOIS and IDENTIFY commands to send the request
3054 to router only if it includes nicknames or other names. If
3055 they include only IDs then check the local cache first before
3056 routing. Affected file is silcd/command.c.
3058 * Added channels topic announcements. Affected file is
3059 silcd/packet_receive.c and silcd/server.c.
3061 * Fixed the silc_server_send_notify_topic_set to really destine
3062 the packet to channel. Affected file silcd/packet_send.c.
3064 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3065 library. Affected file lib/silcclient/client_notify.c.
3067 * Added UMODE announcements. Affected file silcd/server.c.
3069 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3071 * Memory leak fixes in:
3073 lib/silcutil/silcsockconn.c
3074 lib/silcske/silcske.c
3075 lib/silcske/groups.c
3077 lib/silccrypt/silcpkcs.c
3078 lib/silccore/silccommand.c
3079 lib/silccore/silcidcache.c
3084 * ROBOdoc documented the lib/silcske/groups.h file and a
3085 bit changed the interface for better.
3087 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3089 * Update the client entry context in the ID cache after
3090 nick change. Affected file lib/silcclient/command.c.
3091 Fixes the CUMODE command when regaining founder privileges,
3092 and a little WHOIS problem.
3094 * Fixed silc_net_gethostbyname to correctly call the
3095 inet_ntop. Affected file lib/silcutil/silcnet.c.
3097 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3099 * Added IPv6 support checking to the configure.in.pre, added
3100 also --enable-ipv6 option to override the check. Affected
3101 file configure.in.pre.
3103 * The silc_thread_create now calls the start function
3104 directly if threads support is not compiled in. Removes
3105 ugly #ifdef's from generic code. Affected files are
3106 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3108 * Added silc_net_gethostby[name/addr]_async to asynchronously
3109 resolve. Affected files are lib/silcutil/silcnet.[ch].
3111 * Added support for rendering IPv6 based server, client and
3112 channel IDs. Affected file lib/silcutil/silcutil.c.
3114 * Added support for creating IPv6 based server IDs. Affected
3115 file is silcd/serverid.c.
3117 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3119 * Added silc_net_gethostby[addr/name] into the
3120 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3121 routines. Added silc_net_is_ip[4/6]. Affected file is
3122 lib/silcutil/unix/silcunixnet.c. All routines that take
3123 address as argument now supports both IPv4 and IPv6 addresses.
3125 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3127 * Fixed LIST command reply sending in server. Affected file
3130 * Server now sends the kicker's client ID in the KICK notify
3131 to the kicked client. Affected file silcd/command.c.
3133 * The client library now parses the kickers client ID and
3134 UI displays it. Affected files lib/silcclient/client_notify.c
3135 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3137 * Made all payload parsing function prototypes consistent.
3138 They all take now const unsigned char * and uint32 pair as
3139 the payload data instead of SilcBuffer. Changes all around
3140 the source tree. Other unsigned char* -> const unsigned char*
3141 changes around the tree as well.
3143 * Optimized SFTP client and server packet sending not to
3144 allocate new buffer for each packet but to recycle the
3145 first allocated buffer. Affected files are
3146 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3148 * Optimized the SFTP client to use SilcList instead of
3149 SilcDList for requests, because it is faster. Affected file
3150 is lib/silcsftp/sftp_client.c.
3152 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3153 into lib/silccore/silcid.[ch].
3155 Renamed silcpayload.[ch] into silcargument.[ch].
3157 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * If client entry is deleted with active key agreement
3160 session, abort the session.
3162 The silc_client_abort_key_agreement now calls the completion
3163 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3165 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3168 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Don't use __restrict in older GCC's. Affected file is
3171 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3173 * silc_net_localhost now attempts to reverse lookup the
3174 IP/hostname. Affected file lib/silcutil/silcnet.c.
3176 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3177 command. It can be used to gain founder privileges at
3178 the same time when joining the channel.
3180 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3181 kicker's client ID as well. Updated protocol specs.
3183 Defined that the server must send SILC_COMMAND_IDENTIFY
3184 command reply with error status to client who sent
3185 private message with invalid client ID.
3187 Updated the protocol specification.
3189 * Added silc_server_send_command_reply to send any
3190 command reply. Affected file silcd/packet_send.[ch].
3192 * Added silc_id_payload_encode_data to encode ID payload
3193 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3195 * The server now send IDENTIFY command reply with error
3196 status if client ID in private message is invalid. Affected
3197 file silcd/packet_receive.c.
3199 * Save the server key file with server's IP address in
3200 the filename instead of hostname. The affected file is
3201 irssi/src/silc/core/client_ops.c.
3203 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3208 * Added libtool support for compiling shared objects in
3209 lib/silcsim. Affected file configure.in.pre and
3210 lib/silcsim/Makefile.am. Original patch by cras.
3212 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Pid file configuration, and server's config file fixes
3215 patch by toma. Updated CREDITS file.
3217 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Fixed silc_client_channel_message to not try to decrypt
3220 the message twice if it resolved the destination client
3221 information. This could cause of dropping one channel
3222 message. Affected file lib/silcclient/client_channel.c.
3224 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3227 lib/silcclient/client.c. This function is used when the SILC
3228 Client is run under some other scheduler, or event loop or
3229 main loop. On GUI applications, for example this may be
3230 desired to used to run the client under the GUI application's
3231 main loop. Typically the GUI application would register an
3232 idle task that calls this function multiple times in a second
3233 to quickly process the SILC specific data.
3235 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3237 * Fixed silc_server_drop() for dropping the supplementary
3238 groups as well, this could cause a security hole on some
3241 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3243 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3246 * Write PID file after dropping privileges. Added -F option
3247 to run server on foreground. A patch by debolaz.
3248 Affected files silcd/server.c, silcd/silcd.c.
3250 * Fixed MOTD to return the MOTD file server name. Affected
3251 file silcd/command.c.
3253 * Added INFO command reply handling to the Irssi SILC Client.
3254 Affected file irssi/src/silc/core/client_ops.c.
3256 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * Fixed the silc_idcache_list_* routines to really support
3259 the dynamic list. Fixes a crash. Affected file is
3260 lib/silccore/silcidcache.c.
3262 * Fixed the LIST command reply to really call LIST command's
3263 pending callbacks. Affected file silcd/command_reply.c.
3265 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Update conn->local_entry->nickname after giving NICK
3268 command. Affected file lib/silcclient/command.c.
3270 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3272 * Added the [pid] option to the silcd configuration file
3274 Affected files: serverconfig.[ch] and silcd.c
3276 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Save fingerprint in WHOIS command reply in server.
3279 Affected file silcd/command_reply.c.
3281 * Fixed NICK commands pending callback registration.
3282 Affected file lib/silcclient/command.c.
3284 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3286 * Use ++server->cmd_ident when sending commands in server,
3287 instead of random number. Affected file silcd/command.c.
3289 * Fixed GETKEY command reply to call actually GETKEY pending
3290 command callbacks. Affected file silcd/command_reply.c.
3292 * A bit stricter check for nicknames. Check for same nickname
3293 in NICK command also. Affected file silcd/command.c.
3295 * Do not call INFO command everytime client ID changes, only
3296 during first connecting. Affected file lib/silcclient/client.c.
3298 * Set the new nickname only after successful command reply for
3299 NICK command is returned by server. Affected file
3300 lib/silcclient/command.c.
3302 * Remove nicknames from nicklist during server_signoff notify.
3303 Should fix /NAMES bit more. The affected file is
3304 irssi/src/silc/core/silc-channels.c.
3306 * Added `fingerprint' field to the SilcIDListData in the
3307 silcd/idlist.h to hold the fingerprint of the client's
3310 Send the fingerprint of the client's public key in WHOIS
3313 Affected files silcd/command.c, and silcd/idlist.[ch].
3315 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3316 create fingerprint from given data.
3318 * Show the fingerprint of the client's public key in WHOIS.
3319 Affected files irssi/src/module-formats.[ch] and
3320 irssi/src/silc/core/client_ops.c.
3322 * Format the multiple same nicknames also during JOIN and
3323 NICK_CHANGE notifys. Affected file is
3324 lib/silcclient/client_notify.c.
3326 * Do not print error on screen for invalid private message
3327 payload since it can come if someone is sending private
3328 messages with wrong key. Affected file
3329 lib/silccore/silcprivate.c.
3331 * Fixed multiple concurrent /PING crash. Affected file
3332 lib/silcclient/command.c.
3334 * Changed the wrong ID encoding. All IP addresses must be
3335 in MSB first order in encoded format. They were encoded
3336 wrong and was in LSB format. Affected files are
3337 silcd/serverid.c, lib/silcutil/silcutil.c.
3339 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3341 * Call the `connect' client operation through the scheduler
3342 in case of error. Affected file lib/silcclient/client.c.
3344 * Call the `failure' client operation even if the error
3345 occurred locally during a protocol. Affected file is
3346 lib/silcclient/protocol.c.
3348 * Added support of sending LIST command to router from normal
3349 server. This way normal server can get list of all channels
3350 in the network too. Fixed the channel list sending in the
3351 server too. Affected files are silcd/command.c, and
3352 silcd/command_reply.[ch].
3354 * Added silc_server_update_channels_by_server and
3355 silc_server_remove_channels_by_server. They are used during
3356 disconnection of primary router and in backup router protocol.
3357 Affected file silcd/server_util.[ch], silcd/server.c and
3358 silcd/server_backup.c.
3360 * Fixed channel adding to global list in IDENTIFY command
3361 reply in server. Affected file silcd/command_reply.c.
3363 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * If the incoming packet type is REKEY or REKEY_DONE process
3366 that packet always synchronously. Fixes yet another MAC
3367 failed error on slow (dialup) connections. Affected file
3368 lib/silcclient/client.c and silcd/server.c.
3370 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Call check_version SKE callback for initiator too. Affected
3373 file lib/silcske/silcske.c.
3375 * Implemented fix for security hole found in the SKE that was
3376 fixed in the specification few days back; the initiator's
3377 public key is now added to the HASH value computation.
3378 Added backwards support for the old way of doing it too, for
3379 old clients and old servers. Affected file is
3380 lib/silcske/silcske.c.
3382 * Enabled mutual authentication by default in SKE. If initiator
3383 is not providing mutual authentication the responder will
3384 force it. This will provide the proof of posession of the
3385 private key for responder. The affected files are
3386 lib/silcclient/protocol.c and silcd/protocol.c.
3388 * Do not cache anymore the server's public key during SKE.
3389 We do mutual authentication so the proof of posession of
3390 private key is done, and if the server is authenticated in
3391 conn auth protocol with public key we must have the public
3392 key already. Affected file silcd/protocol.c.
3394 * Added new global debug variable: silc_debug_hexdump. If
3395 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3396 file lib/silcutil/silclog.[ch].
3398 * Fixed compilation warning due to char * -> const char *.
3399 Affected files lib/silcutil/silcnet.h, and
3400 lib/silccore/silcauth.[ch].
3402 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3404 * Fixed CMODE command when new channel key was created. If
3405 the creation failed the old key was removed. Next time giving
3406 same command would crash the server since the old key was
3407 freed already. Affected file silcd/command.c.
3409 * Fixed the silc_server_announce_get_channels to not crash
3410 on reconnect. Affected file silcd/server.c.
3412 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Added silc_log_set_debug_string function to set a regex
3415 string to match for debug output. Only the function names,
3416 or filenames matching the given debug string is actually
3417 printed. This way it is possible to filter out those debug
3418 strings that user is not interested in.
3420 Fixed a bug in silc_string_regexify.
3422 Affected files lib/silcutil/silclog.[ch], and
3423 lib/silcutil/unix/silcunixutil.c.
3425 * Changed the -d options in both server and Irssi SILC client
3426 to take the debug string as argument. Affected files
3427 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3429 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Added silc_hash_babbleprint to create a Bubble Babble
3432 Encoded fingerprint. The encoding is developed by Antti
3433 Huima (draft-huima-babble-01.txt), and it creates human
3434 readable strings out of binary data. Affected file
3435 lib/silccrypt/silchash.[ch].
3437 * Print the babble print now in addition of fingerprint as well
3438 in Irssi SILC client. Affected files are
3439 irssi/src/fe-common/silc/module-formats.[ch],
3440 irssi/src/fe-common/silc/core/client_ops.c.
3442 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3444 * Fixed a security problem found in SKE. The initiator's
3445 public key too is now added to the HASH hash value creation
3446 which is signed by the responder to create the SIGN value.
3447 This will prevent anyone in the middle to lie to the responder
3448 about the initiator's public key. If this is done now, the
3449 man in the middle will get caught. Updated the protocol
3452 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Better installation directory handling. Configure module
3455 paths and other paths automatically to example_silc* files
3456 in doc/. A patch by toma.
3458 * Fixed compiler warning from MPI library, and from SILC RNG.
3461 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3462 It can be configured with ./configure. A patch by toma.
3464 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Find correct make to use in prepare-clean. A patch by
3467 toma. Affected file prepare-clean.
3469 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3471 * Added irssi variables use_auto_addr, auto_bind_ip,
3472 auto_bind_port and auto_public_ip.
3474 * Changed the interface for silc_client_send_key_agreement
3475 in lib/silcclient/silcapi.h
3479 irssi/src/silc/core/silc-core.c
3481 lib/silcclient/silcapi.h
3482 irssi/src/silc/core/silc-channels.c
3483 lib/silcclient/client_keyagr.c
3486 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Added silc_pkcs_public_key_compare to compare two
3489 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3491 * Check that the client who set the founder mode on the
3492 channel is the same client that is giving the founder
3493 mode to itself. It is done by comparing the saved public
3494 key (it is saved even in the authentication is passphrase).
3495 Affected file silcd/command.c.
3497 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Do not process packet for disconnected socket connection.
3500 Affected file lib/silccore/silcpacket.c.
3502 * Process the DISCONNECT packet through scheduler in the
3503 client library. Affected file lib/silcclient/client.c.
3505 * Fixed the silc_client_packet_parse to not to increase
3506 the packet sequence number if the conn->sock and the
3507 current socket connection is not same. This can happen
3508 for example during key agreement when the conn includes
3509 multiple socket connections (listeners). Affected file
3510 lib/silcclient/client.c.
3512 * The sender of the file transfer request now provides also
3513 the pointer (listener) for the key exchange protocol. If
3514 the listener cannot be created then it sends empty key
3515 agreement and lets the receiver provide the listener.
3517 Added `local_ip' and `local_port' arguments to the
3518 silc_client_file_send. If they are provided they are used,
3519 if not then it will attempt to find local IP address, if
3520 not found or bind fails then the remote client will provide
3523 Affected files are lib/silcclient/client_ftp.c and
3524 lib/silcclient/silcapi.h.
3526 * Extended the FILE SEND command to support defining the
3527 local IP and port for key exchange listener. They are
3528 optional. Affected file irssi/src/silc/core/silc-servers.c.
3530 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Defined to WHOIS command reply the sending of fingerprint
3533 of the client's public key (if the proof of posession of the
3534 corresponding private key is verified by the server).
3535 Updated to the protocol specification.
3537 * Added support of receiving the client's public key's
3538 fingerprint in command reply in client library. Affected
3539 file is lib/silcclient/command_reply.c, and
3540 lib/silcclient/idlist.[ch].
3542 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Do not send over 128 chars long nickname to the server
3545 in NICK command. Affected file lib/silcclient/command.c.
3547 * Do not send over 256 chars long channel names to the server
3548 in JOIN command. Affected file lib/silcclient/command.c.
3550 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3552 * Assure that silc_server_close_connection cannot be called
3553 twice for same socket context. Affected file is
3556 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Send error message to application if opening file for
3559 writing during file transfer fails. Affected file is
3560 lib/silcclient/client_ftp.c.
3562 Remove all file transfer sessions for a client that we're
3563 removing from ID cache.
3565 Affected file is lib/silcclient/client_ftp.c.
3567 * Fixed silc_net_addr2bin to return correct address. Affected
3568 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3570 * Fixed file transfer session removing on signoff notify.
3571 Affected file irssi/src/silc/core/silc-servers.c.
3573 * Added the SilcClientFileError to be returned in the monitor
3574 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3575 Affected file lib/silcclient/silcapi.h.
3577 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3579 * Fixed a crash in silc_client_ftp_free_sessions and
3580 silc_client_ftp_session_free_client. Affected file
3581 lib/silcclient/client_ftp.c.
3583 * Added `disabled' field in the SilcChannelEntry in the server
3584 to indicate if the server entry is disabled. Affected file
3585 silcd/idlist.h, silcd/command[_reply].c.
3587 * SILC server adds now /var/run/silcd.pid everytime it is
3588 started. Affected file silcd/silcd.c.
3590 * Added silc_server_packet_send_clients to send a packet to
3591 the provided table of client entries. Affected file
3592 silcd/packet_send.[ch].
3594 * Fixed a crash in client resolving in client_prvmsg.c in
3595 client library. Affected file lib/silcclient/client_prvmsg.c.
3597 * Do not actually remove the client directly from ID cache
3598 during SERVER_SIGNOFF, but invalidate it. This way we
3599 preserve the WHOWAS info for the client. Affected file
3600 silcd/server_util.c.
3602 * Fixed SERVER_SIGNOFF notify handling in the server. The
3603 server is now able to process incoming SERVER_SIGNOFF notify
3604 for a server that it doesn't even know about. It will remove
3605 the clients provided in the notify. Affected file
3606 silcd/packet_receive.c.
3608 * Check for partial packet in data queue after every packet that
3609 was found from the queue. Return and wait for more data if
3610 there is partial data in queue. Affected file is
3611 lib/silccore/silcpacket.c.
3613 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Added SilcClietFileError enum to indicate error in
3616 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3617 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3618 Affected files lib/silcclient/silcapi.h and
3619 lib/silcclient/client_ftp.c.
3621 * Check that newsize in silc_buffer_realloc is larger than
3622 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3624 * Added better monitor of file transfers. It now monitors
3625 key agreement protocol during the file transfer too. Added
3626 error reporting too. Affected files
3627 irssi/src/silc/core/silc-servers.c,
3628 irssi/src/fe-common/silc/module-formats.[ch].
3630 * Wrote a help file for FILE command.
3632 * Added silc_rng_global_get_byte_fast to get not-so-secure
3633 random data as fast as possible. Random data is read from
3634 /dev/urandom if available and from the SILC RNG if not
3635 available. It is used in padding generation. Affected file
3636 lib/silccrypt/silcrng.[ch].
3638 * All packets in client library are now processed synchronously.
3639 Optimized packet processing a lot. Affected file
3640 lib/silcclient/client.c.
3642 * All server connection packets are processing synchronously
3643 now in server, to optimize packet processing. Affected file
3646 * Include files are installed now only in Toolkit distribution
3647 if make install is given. Affected files: all Makefile.am's.
3649 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Assure that silc_client_notify_by_server_resolve does not
3652 resolve the client information multiple times. If it cannot
3653 be found by the first it cannot be found at all. Affected
3654 file lib/silcclient/client_notify.c.
3656 * Fixed WHOWAS command reply calling. Affected file
3657 lib/silcclient/command_reply.c.
3659 * Removed all references to silc_idlist_get_client from the
3660 Irssi SILC client since that call is internal call used by
3661 the library. The Irssi SILC client will use now client
3662 retrieval functions found in silcapi.h.
3664 * Fixed a bug in resolving nickname info before sending
3665 private message. It used freed memory. Affected file
3666 irssi/src/silc/core/silc-servers.c.
3668 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3687 * Added silc_net_localip to return local host's IP address.
3688 Affected file lib/silcutil/silcnet.[ch].
3690 * If key exchange or rekey protocol is active for a connection
3691 parse all packets syncronously since there might be packets
3692 in packet queue that we are not able to process without first
3693 processing packets before them. Affected file silcd/server,
3694 lib/silcclient/client.c.
3696 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3697 whether library should continue processing the packet.
3698 Affected file lib/silccore/silcpacket.h.

3744 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3745 is incomplete and is being resolved, it won't be resolved
3748 Make sure also that USERS command reply does not resolve
3749 twice information. Affected file is
3750 lib/silcclient/command_reply.c.
3752 Make sure that silc_client_get_clients_by_list does not
3753 resolve twice same information.
3755 * Check for valid client->id in the silc_server_free_client_data.
3756 Affected file silcd/server.c.
3758 * Fixed /GETKEY nick@server not to crash if the server entry
3759 is not found. Affected file lib/silcclient/command.c.
3761 * Fixed the silc_server_check_cmode_rights to check the
3762 requested modes correctly. Affected file silcd/command.c.

3766 * Better checks for non-printable chars in nick added.
3767 Affected file silcd/command.c.
3769 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Call the silc_server_udpate_servers_by_server in the
3772 primary router that comes back online in the backup resuming
3773 protocol. Otherwise it routes packets wrong. Affected file
3774 silcd/server_util.[ch], silcd/server_backup.c.
3776 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3779 lib/silcutil/silcbuffmt.[ch].
3781 * Redefined the SILC packet header to include the padding
3782 length. Affected file lib/silccore/silcpacket.[ch].
3784 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3785 length for maximum padding up to 128 bytes). Affected
3786 file lib/silccore/silcpacket.h.
3788 * Removed all backwards support for old 0.5.x MAC thingies.
3789 The SILC packet header change makes it impossible to be
3790 backwards compatible.
3792 * Send the ENDING packet with timeout in the backup resuming
3793 protocol. This is to assure that all routers has connected
3794 to the primary router. Affected file silcd/server_backup.c.
3796 * Changed the RNG to take the first IV from random data. It
3797 used to take it from zero actually. Changed the RNG also
3798 to use /dev/urandom during session. /dev/random is used
3799 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3801 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3803 * Changed the SILC packet header to have the first two bytes
3804 (the packet length) encrypted. Affected files aroung the
3805 code tree, lib/silccore/silcpacket.[ch]. Removed the
3806 SilcPacketCheckDecrypt callback. It is not needed anymore
3807 since the silc_packet_receive_process will determine now
3808 whether the packet is normal or special.
3810 * Implemented the unidirectional MAC keys. Affected files
3811 lib/silcske/silcske.c, silcd/protocol.c and
3812 lib/silcclient/protocol.c.
3814 * Implemented the packet sequence number to the MAC computation.
3815 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3816 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3817 lib/silcclient/protocol.c.
3819 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Allow backup router to announce servers. All servers
3822 announced by backup router are added to the global list
3823 automatically. Update hte server's socket to our primary
3824 router also when backup router announces a server.
3825 Affected file silcd/packet_receive.c.
3827 * Do not update the client->router in the function
3828 silc_server_udpate_clients_by_server if the client is on
3829 global list. We might fail to find any specific server
3830 for locally connected clients and local cell clients. They
3831 should still use the `from' and not `to' as client->router.
3832 This fixes backup router resuming protocol. Affected file
3833 silcd/server_util.c.
3835 * Decrease channel statistics count only if the channel
3836 deletion worked. Affected files are silcd/server.c and
3837 silcd/server_util.c.
3839 * Added silc_server_update_servers_by_server to update origin
3840 of all server entries. Used during backup router protocol.
3841 Affected files silcd/server_util.[ch], silcd/server.c. and
3842 silcd/backup_router.c.
3844 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3845 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3846 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3847 lib/silccrypt/silchmac.c.
3849 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3851 * Assure that router cannot reroute the same channel message
3852 to the sender. Affected file silcd/packet_receive.c.
3854 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Made better checks that the channel message is not sent
3857 to the router it came from. Affected file is
3858 silcd/packet_send.c. Fixed memory leak too.
3860 * Announce informations for incoming router connection, but
3861 only after checking if it is replaced by backup router.
3862 Affected file silcd/packet_receive.c.
3864 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Fixed the backup resuming protocol to work in multiple
3867 router environment. Affected file silcd/server_backup.c.
3869 * Route packet only to one router in the function
3870 silc_server_packet_send_to_channel. Affected file is
3871 silcd/packet_send.c.
3873 * Fixed silc_server_send_notify_dest to set the broadcast
3874 flag. Fixed the silc_server_send_notify_topic to actually
3875 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3876 Affected file silcd/packet_send.c.
3878 * Changed the SFTP Filesystem interface. Changed the
3879 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3880 the filesystem operation function. The SilcSFTPFilesystem
3881 is now a context that is allocated by all filesystem allocation
3882 functions and it already includes the operations structure
3883 and filesystem specific context. It is given as argument
3884 now to the silc_sftp_server_start. This made the interface
3885 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3886 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3888 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3890 * Changed the backup router adding and getting interfaces
3891 in the server. The router that will be replaced by the
3892 specified backup router is now sent as argument. Affected
3893 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3896 * Added silc_net_addr2bin_ne to return the binary form of
3897 the IP address in network byte order. Affected files
3898 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3900 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3902 * Check for existing server ID in silc_server_new_server
3903 and in silc_server_connect_to_router_final and remove the
3904 old entry if it exists. Affected file silcd/packet_receive.c,
3907 * Send the channel message always to only one router, either
3908 in upstream or downstream. Affected file is
3909 silcd/packet_send.c.
3911 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Wrote the definition of the backup resuming protocol to the
3914 protocol specification.
3916 * Removed one redundant channel key generation from normal
3917 server during joining procedure. Removed one redundant
3918 channel key sending from server to router during joining
3919 procedure. Affected file silcd/command.c.
3921 * Made minor bugfixes to the backup router resuming protocol.
3922 Affected file silcd/server_backup.c, server.c.
3924 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Added --disable-asm configuration option. Affected files
3927 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3930 * Implemented the backup resuming protocol that is used to
3931 resume the primary router position in the cell after the
3932 primary router comes back online. Affected files
3933 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3934 and silcd/server_util.[ch].
3936 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * Sleep two (2) seconds after sending QUIT command to server.
3939 Affected file lib/silcclient/command.c.
3941 * Assure that if outgoing data buffer is pending do not force
3942 send any data. Affected file silcd/packet_send.c.
3944 * Assure that if outgoing data buffer is pending do not force
3945 send any data. Affected file lib/silcclient/client.c.
3947 * Implemented the backup router support when the primary router
3948 goes down. The servers and routers can now use the backup
3949 router as new primary router without loosing connectivity.
3951 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3954 in the server to indicate disabled entry. All data read
3955 from the connection will be ignored and no data is sent
3956 for entry that is disabled. Affected files are
3957 silcd/idlist.h, silcd/server.c.
3959 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Created SFTP client and server test programs in the
3962 lib/silcsftp/tests directory.
3964 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Implemented memory filesystem (virtual filesystem) for
3967 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3970 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * Implemented the SFTP (SSH File Transfer Protocol) to the
3973 lib/silcsftp. It includes SFTP client and SFTP server
3976 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3978 * Moved lib/silccore/silcprotocol.[ch] to the
3979 lib/silcutil library.
3981 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3982 take variable argument list pointer as argument. Affected
3983 file lib/silcutil/silcbuffmt.[ch].
3985 * Added silc_buffer_set function that is used to set data
3986 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3987 Affected file lib/silcutil/silcbuffer.h.
3989 * Changed various routines in the core library to use the new
3990 silc_buffer_set instead of allocating new buffer only for
3993 * Added 64-bit value formatting and unformatting support to the
3994 silc_buffer_[un]format routines. Affected file is
3995 lib/silcutil/silcbuffmt.[ch].
3997 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3998 to includes/bitmove.h.
4000 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Fixed channel user mode saving in client library. Affected
4003 file lib/silcclient/command[_reply].c.
4005 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4007 * Defined the file transfer to the SILC Protocol. Added
4008 new packet type SILC_PACKET_FTP and defined File Transfer
4009 Payload. The mandatory file transfer protocol is SFTP
4010 (SSH File Transfer Protocol). Affected file in addition
4011 of the internet draft is lib/silccore/silcpacket.h.
4013 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4014 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4015 is used as part of backup router protocol when the primary
4016 router of the cell is back online and wishes to resume
4017 the position as primary router.
4019 * Redefined the MAC generation keys in the protocol. The
4020 same key is not used anymore in both direction. Both
4021 direction will now use different keys for sending and
4022 receiving. This fixes a potential security flaw. This
4023 change causes incompatibilities in the protocol.
4025 * Redefined also the MAC computation from the packet.
4026 An packet sequence number is now added to the MAC
4027 computation. This prevents possible replay attacks against
4028 the protocol. This change too causes incompatibilities
4031 Added `sequence' field to the SilcPacketContext to hold
4032 the current sequence number for the packet.
4034 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * Added `created' field to the SilcIDListData in the file
4037 silcd/idlist.h to indicate the time when the entry was
4040 * Added `created' field to the SilcChannelEntry too. Affected
4041 file silcd/idlist.h.
4043 * Added `creation_time' aguments to all the announcement functions
4044 in the server. If it is provided then only the entries that
4045 was created after the provided time frame are actually
4046 announced. Affected file silcd/server.[ch].
4048 * The protocol says that the Channel ID's IP address must be
4049 based on the router's IP address. Added check for this in
4050 the silc_server_new_channel when processing incoming New Channel
4051 Payload. Affected file silcd/packet_receive.c.
4053 * Print out the correct version with --version in SILC client.
4054 Affected file irssi/src/silc/core/silc-core.c.
4056 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4058 * Fixed WHOWAS command to check for completnes of the client
4059 entry always, not just when the command is coming from client.
4060 Affected file silcd/command.c.
4062 * Added new function silc_server_packet_queue_purge to purge the
4063 outgoing data queue to the network. After the function returns
4064 it is guaranteed that the outgoing packet queue is empty.
4065 Affected file silcd/packet_send.[ch].
4067 * Purge the outgoing packet queue in the rekey protocol's final
4068 callback to assure that all rekey packets go to the network
4069 before quitting the protocol. Affected file silcd/server.c.
4071 * Added silc_client_packet_queue_parse as similar function as
4072 in server to the client library. The affected file is
4073 lib/silcclient/client.c.
4075 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4077 * Splitted silcd/server.c and created silcd/server_util.[ch]
4078 for utility functions.
4080 * Added new socket flag SILC_SF_DISABLED to indicate that the
4081 connection is open but nothing can be sent to or received from
4082 the connection. Affected file lib/silcutil/silsockconn.[ch].
4083 The checking for disabled socket is checked in the low level
4084 silc_socket_write and silc_socket_read functions.
4086 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4088 * Allow only nicknames and channel names that fits into the
4089 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4091 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4093 * When processing JOIN command reply in server check that if
4094 the channel exists in our global list we'll move it the local
4095 list. Affected file silcd/command_reply.c.
4097 * Fixed the check whether client is joined on the channel already
4098 in JOIN command. Affected file lib/silcclient/command.c.
4100 * Fixed the JOIN command reply to check whether the channel
4101 already exists. Affected file lib/silcclient/command_reply.c.
4103 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * Added silc_ske_status_string to map the SKE error numbers
4106 to readable strings. The affected files are
4107 lib/silcske/silcske[_status].[ch].
4109 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4111 * Do not show the private channels on the WHOIS channel list
4112 as it is not allowed by the protocol. The affected file is
4115 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Assure that the packet length digged from the actual packet
4118 is something sensible in the silc_packet_decrypt_rest_special
4119 in lib/silccrypt/silcpacket.c.
4121 * Free and NULL the allocated pointer in silc_hmac_alloc if
4122 the HMAC allocation fails. The affected file is
4123 lib/silccrypt/silchmac.c.
4125 * Print the selected security properties to the log files in
4126 the server. Affected file silcd/protocol.c.
4128 * Add SKE's reference counter even if calling the completion
4129 callback manually. Otherwise it goes negative, although it
4130 does not cause any problems. The affected file is
4131 lib/silcske/silcske.c.
4133 * Remove the client entry with short timeout after giving the
4134 KILL command. Affected file lib/silcclient/command.c.
4136 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4137 case all found clients are already disconnected (WHOWAS would
4138 found them) in the server. Affected file silcd/command.c.
4140 * Update the last_receive (time of last data received) to be
4141 updated only when received private or channel message so that
4142 the idle time showed in WHOIS makes more sense.
4144 * Added boolean field `valid' in to the SilcClientEntry in the
4145 client library to indicate whether the entry is valid or not.
4146 This fixes the nickname change bug on channel when changing
4147 the nickname to be same than the old (like nick to Nick) the
4148 nickname formatter doesn't set the new nick anymore to Nick@host.
4149 Affected file lib/silcclient/idlist.[ch].
4151 * Now actually fixed the nickname changing on disconnection.
4152 Added new function silc_change_nick to the Irssi SILC Client.
4153 Affected file irssi/src/silc/core/client_ops.c,
4154 irssi/src/silc/core/silc-nicklist.[ch].
4156 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4158 * Check that the public key exists in the GETKEY command before
4159 trying to encode it. Affected file silcd/command.c.
4161 * Print some notifications on received public keys with GETKEY
4162 command in the Irssi SILC Client. Affected files are
4163 irssi/src/fe-common/silc/module-formats.[ch],
4164 irssi/src/silc/core/client_ops.c.
4166 * Use IDENTIFY command to resolve the server information in the
4167 GETKEY command instead of INFO command. Affected file
4168 lib/silcclient/command.c.
4170 * All command reply functions in the client library now calls
4171 the pending command reply callbacks even if an error has
4172 occurred. The server has done this a long time and now it was
4173 time to move the client library to this as well. Now all
4174 errors can be delivered back to the pending command reply
4175 callbacks if necessary. Affected files are
4176 lib/silcclient/command[_reply].[ch].
4178 * Change the nickname on disconnection back to the username
4179 because in reconnect the server will enforce it to it anyway.
4180 Affected file irssi/src/silc/core/silc-servers.c.
4182 * Fixed a config file parsing bug in the Irssi SILC client.
4183 Affected file irssi/src/silc/core/clientconfig.c.
4185 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4187 * When printing the channel mode on JOIN, verify that the
4188 channel key and channel's HMAC are valid. Affected file
4189 irssi/src/silc/core/client_ops.c.
4191 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4194 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4195 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4197 * Removed channel key rekey task deleting from the function
4198 silc_server_save_channel_key. Affected file silcd/server.c.
4199 Added explicit timeout task context instead that is used to
4200 delete the task if we are registering a new task before the
4201 new task has elapsed.
4203 * When channel key rekey occurs the client library now saves
4204 the old channel key for a short period of time (10 seconds) and
4205 is able to use it in case some is still sending channel
4206 messages encrypted with the old key after the rekey. Affected
4207 file lib/silcclient/[idlist.h|client_channel.c].
4209 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4211 * Added check to the silc_server_new_id_real to not accept
4212 new ID if it is the sender's own ID. Affected file is
4213 silcd/packet_receive.c.
4215 * Assure that we do not announce ourself or the one we've
4216 sending our announcements when we're router and are announcing
4217 servers to our primary router. Affected file silcd/server.c.
4219 * Fixed silc_server_command_identify_check_client to assemble
4220 correct WHOIS packet. It send corrupted WHOIS packet and
4221 caused problem with router to router connections. Affected
4222 file silcd/command.c.
4224 Fixed also silc_server_command_whois_check the same way
4225 as for the IDENTIFY command.
4227 * Added new SilcIDListStatus to the server in the SilcIDListData
4228 structure. The status now includes the current status of
4229 the entry (like registered, resolved etc.). Affected file
4230 silcd/idlist.[ch]. Defined a bunch of different status types
4231 as well. This replaced the old boolean registered field as well.
4233 Added resolve_cmd_ident field to the SilcClientEntry structure
4234 too so that if the entry is for example being resolved so
4235 another command may attach to the same pending command reply
4236 without requiring to resolve the same entry again. This concept
4237 should optimize the WHOIS and the IDENTIFY resolving under
4238 heavy load by taking away unnecessary resolving for entries
4239 that are being resolved already.
4241 Added support for adding multiple pending commands for one
4242 command idenfier. Affected file silcd/command[_reply].[ch].
4244 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4245 before deleting the data. Otherwise the hash table will have
4246 freed data in comparison functions. Affected file is
4247 silcd/command_reply.c.
4249 * Fixed silc_idlist_replace_client_id to add the new entry to
4250 the cache with NULL nickname. Otherwise there will be invalid
4251 memory as the nickname after the nickname is freed. Affected
4252 file silcd/packet_receive.c.
4254 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4255 saved into wrong slots because the previous number of entries
4256 was not taken into account. Affected file silcd/idlist.c.
4257 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4259 * If we are router and we receive JOIN notify to a channel that
4260 does not have any users then notified client is marked as the
4261 channel founder, as it is it. The affected file is
4262 silcd/packet_receive.c
4264 * Added to the extended hash table API's table_del_*ext functions
4265 the destructor as argument too, so that the caller can decide
4266 which destructor to use or whether to use destructor at all.
4267 Affected file lib/silcutil/silchashtable.[ch].
4269 * Fixed ID Cache purging. It actually deleted the entries from
4270 the hash table after the data was freed. The hash table ended
4271 up comparing freed memory. The affected file is
4272 lib/silccore/silcidcache.c.
4274 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4276 * Fixed Irssi SILC client's KILL command's HELP syntax.
4278 * The USERS command now resolves the detailed user information
4279 if the userinfo field is missing. Affected file is
4280 lib/silcclient/command_reply.c.
4282 * Do not print error in silc_file_read if the read file does
4283 not exist. Just silently return NULL. Affected file is
4284 lib/silcutil/silcutil.c.
4286 * Fixed the silc_log_output to not wine about NULL filename
4287 and to not create some bogus " " filename. Affected file is
4288 lib/silcutil/silclog.c.
4290 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Fixed various printing bugs on the user interface in the
4293 Irssi SILC Client. Minor changes that were forgotten from
4296 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4298 * Fixed the configure.in.pre and the compilation and distribution
4299 environment to support the new autoconf 2.52. That version is
4300 now required to compile the CVS trunk.
4302 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4304 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4305 to generally parse user@fqdn format strings. Affected file
4306 lib/silcutil/silcutil.c.
4308 * Added nickname_format and nickname_force_format fields to the
4309 SilcClientParams structure. The first one defines the format
4310 for the nicknames that the library will enforce if the receives
4311 multiple same nicknames. The second one is boolean value and
4312 can be used to force the library to always enforce the format
4313 to the nicknames regardles whether there are multiple nicknames
4314 or not. This configurable formatting was employed to flexibly
4315 support accessing multiple nicknames from the user interface.
4316 The userinterface can now set the nicknames to what ever format
4317 they prefer. Affected file lib/silcclient/silcapi.h.
4319 Added function silc_client_nickname_format to the file
4320 lib/silcclient/idlist.c. It performs the nickname formatting.
4322 Added new field `hostname´ to the SilcClientEntry context.
4323 It holds the hostname of the client. Affected file is
4324 lib/silcclient/idlist.h.
4326 * Irssi SILC Client sets the nicknames in nick@hostn format.
4327 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4328 irssi/src/silc/core/silc-core.c.
4330 The WHOIS printing now also shows both the real nickname and
4331 the formatted nickname so that user knows how to access the
4332 user if there are multiple same nicknames cached. Affected
4333 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4334 printing formatting too to take the hostname now as a separate
4335 argument. The Affected file is
4336 irssi/src/fe-common/silc/modules-formats.[ch].
4338 * Changed the silc_client_get_clients_local to accept the formatted
4339 nickname as argument. It accepts the real nickname too but the
4340 formatted nickname can be used to find the true entry from
4341 multiple entries. Affected file lib/silcclient/silcapi.h and
4342 lib/silcclient/idlist.c.
4344 * Added nickname_format_parse field to the SilcClientParams.
4345 It is a callback function provided by the application to parse
4346 the nickname out of the formatted nickname string. The library
4347 calls it to get the nickname from the formatted string. Since
4348 the application generally knows better the format of the nickname
4349 string it parses it instead of the library, even though library
4350 encodes the formatted string. If the callback function is not
4351 provided then the library will use the string as is. The
4352 affected file is lib/silcclient/silcapi.h.
4354 * All the nickname strings passed to the client library in
4355 commands are now expected to be formatted nickname strings.
4356 If the command does not support the formatted nickname string
4357 it will assume that the sent string is the actual nickname.
4358 Affected file lib/silcclient/command.c.
4360 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4362 * Added public key authentication support to OPER and SILCOPER
4363 commands in the client library. Affected file is
4364 lib/silcclient/command.c.
4366 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4368 * Changed the get_auth_methdod client operation to be asynchronous.
4369 It can be async if the application resolves the authentication
4370 method from the server during the negotiation. Added new
4371 SilcGetAuthMeth completion callback that the application will
4372 call after resolving the authentication method.
4374 Added function silc_client_request_authentication_method that
4375 the application can use to resolve the authentication method
4376 from the server. Added also SilcConnectionAuthRequest callback
4377 that the library will call after the server has replied. The
4378 application can call this function if it does not know the
4379 current authentication method.
4381 Affected files are lib/silcclient/client.c and
4382 lib/silcclient/silcapi.h.
4384 * The Irssi SILC client now automatically resolves the authentication
4385 method incase any configuration information is not present (and
4386 currently there never is). The affected file is
4387 irssi/src/silc/core/client_ops.c.
4389 * Fixed public key authentication from the client library.
4390 Affected file lib/silcclient/protocol.c. Changed also the
4391 protocol specification about the public key authentication in
4392 the connection authentication protocol. The actual data to be
4393 signed is now computed with a hash function before signing.
4395 * Fixed the public key authentication from the server as well.
4396 Affected file silcd/protocol.c.
4398 * Removed the mlock()'s from the memory allocation routines.
4399 Affected file lib/silcutil/silcmemory.c. The ./configure does
4400 not check anymore for the mlock(). Affected file is
4403 * Fixed USERS command in server to allow the execution of the
4404 command for private and secret channels if the client sending
4405 the command is on the channel. Affected file silcd/command.c.
4407 * Fixed silc_client_get_clients_local to return the clients
4408 count correctly. It could return wrong value. Affected file
4409 lib/silcclient/idlist.c.
4411 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4413 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4414 types. The assembler optimizations seemed not to like 64-bit
4415 data types. The assmebler optimizations thus are now enabled
4416 also for BSD systems as opposed to only enable them for Linux.
4418 * Do not check for threads at all on BSD systems. Affected
4419 file configure.in.pre.
4421 * Removed -n and -h options from the Irssi SILC Client since
4422 they are not used in silc.
4424 * Fixed the prime generation to assure that the first digit
4425 of the generated random number is not zero since our conversion
4426 routines does not like number strings that starts with zero
4427 digit. If zero digit is seen the random number is regenerated.
4428 This caused some corrupted RSA keys when the zero first digit
4429 was met. Affected file lib/silcmath/silcprimegen.c.
4431 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Fixed WIN32 configuration in the ./configure script.
4434 Fixed to include xti.h on environments that has it.
4435 Patches by Carsten Ilchmann and andrew.
4437 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4439 * Changed the silc_id_create_client_id to be collision
4440 resistant. It is now assured that there cannot be created
4441 two same client ID's. I suspect that some weird bugs in
4442 the server were actually caused by duplicate Client IDs.
4443 Affected file silcd/serverid.[ch]. A router receiving
4444 new ID now also assures and informs the sending server
4445 if the ID caused collision.
4447 * Changed the silc_id_create_channel_id to also assure that
4448 there are no collisions.
4450 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4452 * Statement about ignoring the Mutual Authentication flag when
4453 performing rekey with PFS was a bit misleading. It is ignored
4454 if it was set in the initial negotiation, it cannot be even
4455 set in the rekey. Fixed in the ke-auth draft. Started the
4456 new versions of the protocol drafts in the doc/.
4458 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4460 * Fixed a bug in silc_client_command_identify_save when saving
4461 new channel information. The channel name was no duplicated
4462 and caused crash on exit. Affected file is
4463 lib/silcclient/command_reply.c.
4465 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Fixed the getkey command handling in the server. Send just
4468 empty OK reply to the sender if the key could not be fetched
4469 (but everything else was ok, like the key just was not available).
4470 Changed the public key parameter to optional in the protocol
4471 specs so that empty OK reply can be sent. Affected file
4474 Added a message to Irssi SILC client to tell to user if the
4475 server did not return a public key.
4477 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Fixed a channel key regeneration bug. It registered new
4480 timeout tasks exponentially until all system resources were
4481 used. Affected file silcd/server.c.
4483 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4485 * Added the SILC Document generator to the scripts/silcdoc.
4486 It can be used to generate the Toolkit Reference Manual out
4487 of the source tree. Internally it will also use the RoboDoc
4488 generator now imported in util/robodoc.
4490 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4492 * Added couple of return's in rekey protocol if error orccurred
4493 during the protocol. The execution must be terminated.
4494 Affected file silcd/protocol.c. Also, terminate the protocol
4495 always with timeout.
4497 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4499 * The client's Client ID was created initally from the wrong
4500 nickname (it could have been in format nick@host) in the
4501 silc_server_new_client. Affected file silcd/packet_receive.c
4503 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4505 * Added some SILC_LOG_ERROR's to various error conditions
4506 if client could not be added to ID cache. Affected files
4507 silcd/packet_receive.c and silcd/server.c.
4509 * When client's sock->user_data is freed, NULL also the
4510 client->router and client->connection pointers. Added check
4511 for these pointers being NULL to various places around the
4512 code. Affected file silcd/server.c.
4514 * Added client->data.registered == TRUE checks to various
4515 places around the code to assure that unregistered client's
4516 are not handled when it is not allowed. Affected file
4519 * Added `bool registered' fields to all
4520 silc_idlist_[server|client]_get_* routines to indicate whether
4521 the fetched client needs to be registered or not. Affected
4522 file silcd/idlist.[ch].
4524 * Add your own entry as registered to the ID cache in the
4525 server. Affected file server.c.
4527 * Fixed a bug in silc_server_new_server. The SilcServer was
4528 set as the new server's context instead of SilcServerEntry.
4529 This naturally caused some weird bugs.
4531 * Added "updated" field the SilcChannelEntry which indicates
4532 the time since the channel entry was last accessed. This
4533 can be used to determine whether it is necessary to
4534 announce the channel after backup resuming protocol.
4535 Affected files silcd/idlist.[ch].
4537 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Do not delete the channel rekey task when adding it
4540 for in silc_server_create_channel_key.
4542 * Changed the silc_server_create_channel_key to return
4543 TRUE or FALSE to indicate the success of the channel key
4546 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * Fixed MSVC++ project files and added missing files to
4549 Makefiles under win32/.
4551 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4553 * Do not add TCP_NODELAY flag if the operating system
4554 does not have it defined. Affected files are
4555 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4557 * Fixed buffer overflow from Irssi SILC Client. Affected
4558 file irssi/src/fe-common/core/themes.c.
4560 * Fixed double free in client library in the file
4561 lib/silcclient/client.c when disconnecting from server.
4563 * Applied double free patch from cras to Irssi SILC client.
4564 Affected files irssi/src/core/[modules/expandos].c
4566 * Fixed the disconnection handling to Irssi SILC Client.
4567 The application must call silc_client_close_connection
4568 in ops->connect client operation in case of failure of
4569 the connection. Affected file is
4570 irssi/src/silc/core/client_ops.c.
4572 * Do not set sock->protocol to NULL in the function
4573 silc_client_close_connection after executing the protocol's
4574 final callback since the sock might not be valid anymore.
4575 Affected file lib/silcclient/client.c.
4577 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4579 * Do not enable SILC_THREADS if the linking with libpthread
4580 did not happen. Affected file configure.in.pre.
4582 * Added notion to protocol specification that server must
4583 verify the sent authentication payload with CMODE when
4584 setting the channel founder key. Implemented it to the
4585 server. Affected file silcd/command.c.
4587 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4589 * Added _EXTRA_DIST SILC distribution variable to the
4590 distributions file. It is used to conditionally add extra
4591 files or directories to the specific distribution. Affected
4592 files ./prepare, Makefile.am.pre and distributions.
4594 Removed the `_' from the start of the distribution names.
4597 * Added README.WIN32 for instructions to compile the Toolkit
4600 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4602 * Fixed a double free in disconnection in the server. Affected
4603 file is silcd/server.c.
4605 * Fixed the lib/silcske/groups.c to work now also with GMP
4606 MP library. The string conversion did not work when using
4607 specific base and the base is indicated in the string as well.
4609 * Created win32/ directory which now includes MSVC++ specific
4610 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4611 It will appear only in the toolkit distribution
4613 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4615 * Changed the key material distribution function in case when
4616 the hash output is too short. The data is now concatenated
4617 a bit differently than it used to. Made the change to the
4618 SKE protocol specification.
4620 * Added better GMP detection to configure.in.pre. A patch
4623 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4625 * Fixed a minor bug in SKE that might cause some problem on
4626 some platforms. Affected file lib/silcske/silcske.c.
4628 * Added the cookie checking for initiator in the SKE. It checks
4629 that the responder returns the sent cookie unmodified. The
4630 affected file is lib/silcske/silcske.c. Added new SKE
4631 error type INVALID_COOKIE that can be sent during the
4632 negotiation. Fixed some memory leaks as well.
4634 * Added the "invalid cookie" error message to Irssi SILC client's
4637 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4639 * Added `task_max' field to the SilcClientParams to indicate
4640 the maximum tasks the scheduler can handle. If set to zero,
4641 default values are used. Affected file lib/silcclient/silcapi.h.
4643 * Fixed memory leaks in silc_client_close_connection. Affected
4644 file lib/silcclient/client.c.
4646 * Added silc_client_del_client_entry to client library to free
4647 all memory of given client entry. Affected file is
4648 lib/silcclient/idlist.[ch].
4650 * Added new functions silc_client_del_channel and
4651 silc_client_del_server to delete channel and server entries.
4652 Affected file lib/silcclient/[silcapi.h/idlist.c].
4654 * Removed silc_client_del_client_by_id from silcapi.h.
4656 * Fixed the INFO command to return the server's own info
4657 correctly when querying by Server ID. Affected file is
4660 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4662 * Removed the non-blocking settings in WIN32 code in the
4663 silc_sock_[read/write] and added SleepEx instead. Affected
4664 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4665 of input data is now checked with FIONREAD and ioctlsocket.
4667 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4669 * Call silc_schedule_task_del_by_context in the
4670 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4671 Affected file lib/silccore/silcprotocol.c.
4673 * Call silc_protocol_cancel for active protocols in the
4674 silc_server_close_connection if the funtion
4675 silc_server_free_sock_user_data has not been called.
4676 Affected file silcd/server.c.
4678 * Generic tasks cannot be deleted using the del_by_fd
4679 task deleting function since generic tasks does not match
4680 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4682 * Added a notion to SILCOPER help file that the SILCOPER works
4683 only on router server, not on normal server.
4685 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4687 * Added for WIN32 support for the new scheduler as well.
4688 Affected file lib/silcutil/win32/silcwin32schedule.c.
4690 * Fixed the SHA1 implementation to work on various platforms.
4692 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4694 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4695 API. It is part of the scheduler now. Everything else is
4696 as previously but some functions has changed their names.
4697 Checkout the lib/silcutil/silcschedule.h for the interface.
4698 Updated all applications to use the new interface. Affected
4699 files are lib/silcutil/silcschedule.[ch].
4701 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4703 * Found a bug in the SKE implementation. The HASH value,
4704 specified by the protocol, was not computed correctly. The
4705 public key of the responder was not added to the computation
4706 even though it is mandatory. Affected file lib/silcske/silcske.c.
4707 This unfortunately causes incompatibilities with older
4708 clients and servers.
4710 * Added WIN32 specific network init and uninit functions:
4711 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4712 the Winsock2. Affected file lib/silcutil/silcnet.h and
4713 lib/silcutil/win32/silcwin32net.c.
4715 * Set the socket always to nonblocking mode on WIN32 after
4716 reading data or writing data. Affected file is
4717 lib/silcutil/win32/silcwin32sockconn.c.
4719 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4721 * Fixed various compilation problems under WIN32. Affected
4722 files lib/silcutil/win32/silcwin32thread.c and
4723 lib/silcutil/win32/silcwin32schedule.c.
4725 * Removed all _internal.h #includes from public header
4726 files. Internal headers must never be included from
4729 Removed also the lib/silcske/payload_internal.h file.
4731 * All include files that may be needed (public and some others
4732 included by the public headers) by application developers are
4733 now copied to the ./includes directory. It does not copy any
4734 internal headers. Affected file Makefile.defines.pre and all
4735 Makefile.am's under lib/ and subdirs.
4737 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4739 * Do not change the ~/.silc directory's permissions automatically.
4740 Affected file irssi/src/silc/core/clientutil.c.
4742 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4744 * Do not cancel the protocol in silc_server_close_connection
4745 it might cause recursion. Now cancelled in the function
4746 silc_server_free_sock_user_data. Affected file silcd/server.c.
4748 * Fixed the silc_server_remove_clients_by_server to regenerate
4749 the channel keys correctly finally. Added also new function
4750 silc_server_remove_clients_channels to actually do it.
4751 Affected file silcd/server.c.
4753 * Fixed the silc_server_new_channel to not crash by giving
4754 wrong router to the new channel. Affected file is
4755 silcd/packet_receive.c.
4757 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4759 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4760 which is given as argument to the silc_client_alloc now.
4761 It can be used to configure the client and set various parameters
4762 that affect the function of the client.
4764 * The USERS command in server did not check whether the channel
4765 is private or secret. Affected file silcd/command.c.
4767 * Added new argument to the USERS command in protocol specification.
4768 The USERS command now can take the channel name as argument
4769 as well. Added support for this in client and server and
4770 updated the protocol specs.
4772 * Completed the GETKEY command in client. It can be now used
4773 to fetch also servers public key not only some clients.
4774 Affected files lib/silcclient/command[_reply].c.
4776 * Added silc_client_get_server to return server entry by the
4777 server name. Affected files lib/silcclient/silcapi.h and
4780 * Redefined the IDENTIFY command in protocol specification to be
4781 more generic. It now can be used to query information about
4782 any entity in the SILC Network, including clients, servers and
4783 channels. The query may be based either the entity's name
4784 or the ID. Added support for this in both client and server.
4786 Affected files silcd/command.c and lib/silcclient/command.c
4787 and command_reply.c.
4789 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4790 the _from_client and _from_server functions. Affected file
4793 * Added silc_client_get_channel_by_id_resolve to the file
4794 lib/silcclient/silcapi.h to resolve channel information by
4795 its ID. Added also silc_client_get_channel_by_id that
4796 does not resolve it from the server.
4798 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4800 * Added SilcServerEntry context into the client library
4801 to represent one server. The INFO command now allocates
4802 these to save the resolved server info. For now on the
4803 client library will also keep information about servers,
4804 connected and resolved with INFO.
4806 The INFO command now allocates the SilcServerEntry context
4807 and saves the server info there. The COMMAND_REPLY in
4808 the INFO now returns the parameters to application in
4809 same order as defined in the protocol specification.
4811 The entries are cached in the client->server_cache.
4813 * The INFO command is now issued after received the Client ID
4814 from the server. Affected file lib/silcclient/client.c.
4816 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4817 to the application as the mode changer might be server.
4818 It is guaranteed that NULL is not returned anymore to the
4819 application. Affected file lib/silcclient/client_notify.c.
4821 The ID Type is now also passed to the application so that
4822 it can check whether the returned entry is SilcClientEntry
4825 Added new function silc_client_get_server_by_id to return
4826 the server entry by ID. Affected files are the
4827 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4829 * Do not create the channel in the Irssi SILC Client when issuing
4830 the JOIN command but when received the sucessful JOIN command
4831 reply. Otherwise the channel might get created even though we
4832 could not join it. The Affected file is
4833 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4835 * Fixed a channel joining bug in router. The router must also
4836 check the channel modes, invite and ban lists etc. when serving
4837 the JOIN command sent by normal server. Affected file is
4838 silcd/command.c. The router now resolves the client's
4839 information from the server who sent the JOIN command if it
4840 does not know it, and processes the JOIN command only after
4843 * Changed the SilcCommandCb to take new argument; void *context2.
4844 Affected file lib/silccore/silccommand.h
4846 The second argument in the command callbacks in the server now
4847 includes the SilcServerCommandReplyContext if the command was
4848 called as pending command callback from the command reply.
4849 Otherwise it is NULL. When called as pending the status of the
4850 command reply will be checked and if it was erronous the
4851 error will be sent to the original sender of the command.
4852 This way the client always receives the error messages even
4853 though the server was actually the one who received the error
4854 when it resent the command to router, for example. Affected
4855 files silcd/command[_reply].[ch].
4857 * Fixed sending WHOWAS command's error message to client if
4858 the requested client could not be found. It was missing.
4861 * Changed the CMODE and CUMODE commands reply arguments in the
4862 protocol specification. The Channel ID is now sent in both
4863 of the commands to identify the channel. Implemented this
4864 new feature to the client and server. Affected files
4865 lib/silcclient/command_reply.c and silcd/command.c.
4867 * Made better checks for invite and ban lists in the JOIN
4868 command in server. Affected file silcd/command.c.
4870 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4872 * The server now performs the incoming host IP/DNS lookup
4873 using the silc_socket_host_lookup and thus does not block
4874 the server anymore. Affected file silcd/server.c.
4876 * Completed the multi-thread support for SILC Scheduler in
4877 the lib/silcutil/silcschedule.c.
4879 * Fixed the configure.in.pre to detect the pthread correctly
4882 * Fixed a deadlock in silc_task_queue_wakeup in the file
4883 lib/silcutil/silctask.c.
4885 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4887 * Added new function silc_schedule_wakeup that is used in
4888 multi-threaded environment to wakeup the main thread's
4889 schduler. It needs to be used when a thread adds a new task
4890 or removes a task from task queues. After waking up, the
4891 scheduler will detect the task queue changes. If threads
4892 support is not compiled in this function has no effect.
4893 Implemented the wakeup mechanism to both Unix and WIN32
4894 systems. Affected files are lib/silcutil/silcschedule.[ch],
4895 lib/silcutil/unix/silcunixschedule.c and the
4896 lib/silcutil/win32/silcwin32schedule.c.
4898 * Added new function silc_task_queue_wakeup to wakeup the
4899 scheduler by the specified task queue. Affected file
4900 lib/silcutil/silctask.[ch].
4902 * The silc_socket_host_lookup_start now wakes up the scheduler
4903 after adding the timeout task. Affected file is
4904 lib/silcutil/silcsockconn.c.
4906 * The silc_socket_host_lookup is synchronous now if the threads
4907 support is not compiled in. However, the callback is still
4908 called asyncronously through the scheduler, anyway. Affected
4909 file lib/silcutil/silcsockconn.c.
4911 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4913 * Added new function silc_socket_host_lookup to perform
4914 asynchronous IP and FQDN lookups for the socket connection.
4915 Affected files lib/silcutil/silcsockconn.[ch].
4917 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4919 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4920 that may or may not compile the mutex support in.
4922 Changed the silc_mutex_alloc interface. It allocates the
4923 mutex now to the sent pointer and returns TRUE or FALSE.
4925 Affected file lib/silcutil/silcmutex.h.
4927 * Wrote the SILC Task Queue interface to support multi-threads.
4928 Affected file lib/silcutil/silctask.[ch].
4930 * Wrote the SILC Scheduler to support multi-threads. Affected
4931 file lib/silcutil/silcschedule.c.
4933 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4935 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4936 in lib/silcutil/win32/.
4938 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4940 * Defined SILC Mutex API and SILC Thread API and implemented
4941 them for Unix. Affected files are
4942 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4943 lib/silcutil/unix/silcunixmutex.c and
4944 lib/silcutil/unix/silcunixthread.c.
4946 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4948 * Fixed the silc_server_remove_clients_by_server's channel
4949 key re-generation. The hash table handling was incorrect
4950 and would not work with many channels. Affected file is
4953 * Fixed some memory leaks around the server code.
4955 * Rewrote the silc_server_get_users_on_channel to support IPv6
4956 based Client ID's. Affected file silcd/server.c.
4958 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4959 specification. However, a separate document must be written
4960 to define the detailed signing procedure and the payload
4961 associated with the flag. Defined the flag to the
4962 lib/silccore/silcchannel.h as well.
4964 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4966 * Changed the dynamic tables to static size tables in the
4967 lib/silccrypt/silchmac.c.
4969 * Removed GCC dependencies from the code. A patch by cras.
4971 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4973 * Do not show the error "Error receiving packet bla bla"
4974 in server if it really was not an error (-2 means that reading
4975 is pending). Affected file silcd/server.c.
4977 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4979 * Fixed a possible crash in silc_server_remove_clients_by_server
4980 in silcd/server.c. Fixed there also some memory leaks.
4982 * Fixed the silc_idlist_replace_client_id. It could replace
4983 wrong key in the hash table. Affected file silcd/idlist.c.
4985 * Do not check whether there are global users on the channel
4986 if the channel->global_users is FALSE. Affected functions
4987 silc_server_remove_from_one_channel and
4988 silc_server_remove_from_channels in silcd/server.c. Also,
4989 do not check if the removed client is local as we can be
4990 sure that global client was not removed from the channel
4991 and checking for global users is not needed.
4993 * The silc_server_remove_clients_by_server now re-generates
4994 the channel keys correctly for those channels that had
4995 clients removed from them. Affected file silcd/server.c.
4997 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4999 * Found the reason of random crashes in the server. We weren't
5000 ignoring the SIGPIPE signal (which can be sent in write())
5001 and it crashed the server. Affected file silcd/silcd.c.
5003 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5005 * Assure that sock->user_data is not NULL in the function
5006 silc_server_packet_send in silcd/packet_send.c.
5008 * Disconnect the remote connection if it could not be added
5009 to any ID lists in the server. The affected file is
5012 * Check in silc_server_packet_send[_real/dest] that the
5013 socket is not disconnecting and ignore the data if it is.
5014 Affected file silcd/packet_send.c.
5016 * Define inline to __inline on native WIN32 compilation.
5017 Affected file includes/silcwin32.h.
5019 * Added some explicit type casts for inline code since MSVC
5020 require them. Affected files lib/silcutil/silcbuffer.h,
5021 lib/trq/silcdlist.h and lib/trq/silclist.h.
5023 * Print warning in log files from now on if the packet
5024 decryption fails. Affected file silcd/server.c.
5026 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5028 * Changed the `say' client operation's interface to accept
5029 new `type' argument to indicate the type of the message sent
5030 by the library. The application may filter the library's
5031 messages according the type. The affected file is the
5032 lib/silcclient/silcapi.h.
5034 * Added two new functions to lib/silcclient/silcapi.h:
5035 silc_client_del_client and silc_client_del_client_by_id.
5036 Affected file lib/silcclient/idlist.c.
5038 * Moved the clientincludes.h from includes/ to silc/ and
5039 serverincludes.h from includes/ to silcd/.
5041 * The modes for the CMODE and CUMODE are now passed as
5042 uint32 for application with COMMAND_REPLY. The affected
5043 file is lib/silcclient/command_reply.c.
5045 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5047 * /WHOIS without arguments shows client's own information.
5048 Affected file lib/silcclient/command.c.
5050 * Changed PING to not accept any arguments. The specs
5051 says that client can ping only the connected server so
5052 requiring an argument is not needed. Affected file is
5053 lib/silcclient/command.c.
5055 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5057 * Fixed a fatal bug in private message sending and reception
5058 encryption and decryption when using private message keys.
5059 The implementation was incorrect and did not follow the
5060 specification. It causd that some of the message were
5061 lost since it did not use the sending and receiving keys
5062 as the protocol suggests. This has been fixed and will cause
5063 incompatibilities with older clients when sending private
5064 message encrypted with private message keys. Affected files
5065 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5066 and various other in Irssi SILC Client.
5068 Added `responder' boolean argument to the functions
5069 silc_client_add_private_message_key[_ske] to indicate when
5070 the key is added as responder or initiator of the key
5073 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5075 * Removed the silc_ske_check_version function and created
5076 a SilcSKECheckVersion callback. Added also a function
5077 silc_ske_set_callbacks that is now used to set all SKE
5078 callbacks. The callback functions are not given to
5079 the SKE functions anymore, but this function is used to
5082 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5084 * Added `silc_version' argument to the silc_client_alloc
5085 to define the version of the application for the library.
5086 The library will use the version string to compare it
5087 against the remote host's (usually a server) version
5088 string. Affected file lib/silcclient/silcapi.h
5090 * Added the KE protocol context to Key Agreement context
5091 in client library so that we can abort the SKE if it
5092 is in process when we get timeout. Affected file is
5093 lib/silcclient/client_keyagr.c.
5095 * Do not resolve the client ID forever if it returns in the
5096 first time that such client does not exist. This was done
5097 for example with private message. Affected file is
5098 lib/silcclient/client_prvmsg.c.
5100 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5102 * Do not add regex.h for WIN32. The affected file
5103 includes/silcincludes.h.
5105 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5106 not work yet 100%. It generates the DLL's automatically
5107 when compiling with --with-win32 under cygwin.
5109 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5111 * lib/contrib/regex.c is not compiled on WIN32.
5113 * Added silc_net_get_socket_opt function to the
5114 lib/silcutil/silcnet.h.
5116 * Added includes/silcwin32.h for WIN32 specific includes
5119 * Do not use ptime structure or any of the posix process
5120 functions on WIN32 in lib/silccrypt/silrng.c.
5122 * Added silc_gettimeofday to provide generic function
5123 for struct timeval on all platforms. Added the function
5124 to lib/silcutil/silcutil.h.
5126 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5128 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5129 library as they clearly belong there. As a plus side we
5130 can make the actual socket connection routines platform
5133 Added also new generic function silc_socket_read and
5134 silc_socket_write (that used to be silc_packet_[read/write].
5135 The implementation of these are platform specific.
5137 * Added WIN32 specific routines of silc_socket_[read/write]
5138 to lib/silcutil/win32/silcwin32sockconn.c.
5140 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5142 * Added preliminary support for native WIN32 compilation under
5143 cygwin (using the -mno-cygwin option for GCC) to the
5144 ./configure.in.pre. The --with-win32 now prepares the
5145 compilation for native WIN32.
5147 * Rewrote the SILC Scheduler interface in the file
5148 lib/silcutil/silcschedule.h. The scheduler is now context
5149 based and does not have anymore any global static scheduler.
5150 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5151 and created lib/silcutil/win32 directory for WIN32 based
5154 * Added Unix specific network routines to the
5155 lib/silcutil/unix/silcunixnet.c and the old
5156 lib/silcutil/silcnet.c includes now only generic routines.
5158 Added WIN32 specific network routines to the
5159 lib/silcutil/win32/silcwin32net.c.
5161 * Added Unix specific utility functions from the
5162 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5164 * Added WIN32 SILC Scheduler to the file
5165 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5168 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5170 * Do not handle JOIN notify in the server if the target client
5171 is not registered (idata->registered == FALSE). The affected
5172 file is silcd/packet_receive.c.
5174 * Update the nickrec->founder in event_cumode in the Irssi SILC
5175 client. Affected file irssi/src/silc/core/silc-channels.c.
5177 * Fixed the CUMODE_CHANGE notify handling in the server when
5178 server and router are announcing their clients on channels.
5179 Now the mode changes are saved and notified correctly. The
5180 affected file is /silcd/packet_receive.c.
5182 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5183 They really did not replace the cache entry in the ID Cache.
5184 Now they do that. Affected file silcd/idlist.c.
5186 * Fixed the KICK notify handling in the Irssi SILC client to
5187 update the channel records so that the kicked client does not
5188 appear to be on the channel. The affected file is
5189 irssi/src/silc/core/silc-channels.c.
5191 * Always update the conn->current_channel when executing command
5192 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5194 * Fixed the KILL notify handling in Irssi SILC client to remove
5195 the killed client on all channels.
5197 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Fixed the silc_parse_command_line to remove extra spaces
5200 from the start and end of the arguments. Affected file is
5201 lib/silcutil/silcutil.c.
5203 * Cancel and free any active protocol in the function
5204 silc_server_close_connection. Affected file silcd/server.c.
5206 * Cancel and free any active protocol in the function
5207 silc_client_close_connction. Affected file is
5208 lib/silcclient/client.c.
5210 * Do not execute the KILL command for clients that are in
5211 history (ie. they are not in the network). Affected file is
5214 * Fixed KILL notify handling, client does not crash anymore.
5215 Affected file irssi/src/silc/core/silc-channels.c.
5217 * Reduced the default packet buffer size from 2048 to 1024 in
5218 lib/silccore/silcpacket.c.
5220 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5221 counter to the SKE context that is incresed when the SKE library
5222 performs async operation outside the library. If the outside
5223 process frees the SKE context and FREED status will be set
5224 and the library will detect after the sync operation that the
5225 libary is freed. The affected files are
5226 lib/silcske/silcske[_status].[ch].
5228 * Resolve the client entry information in the function
5229 silc_client_channel_message to assure that NULL pointer is not
5230 passed as client entry to the application. */
5232 * Fixed the task timeout calculation to assure that there is
5233 never negative timeouts. The affected file is
5234 lib/silcutil/silcschedule.c.
5236 * Fixed the channel user mode notification sending in server.
5237 It was sent point-to-point to the router (or to server by router)
5238 but it needs to be destined to a channel. The routines now
5239 supports sending the channel user mode notifys to the channels
5240 when announcing clients and channels. Affected files are
5241 silcd/server.c and silcd/packet_receive.c.
5243 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5244 It did not actually replace the old channel entry in the cache.
5245 Affected file lib/silcclient/client_notify.c.
5247 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Fixed a possible crash in silc_packet_send_prepare. It now
5250 assures always that there is enough space in the buffer and
5251 at the tail area of the buffer (for MAC).
5253 Fixed the inbound buffer reallocation in silc_packet_read.
5254 It was old code and did not handle the reallocation correctly.
5257 The affected file is lib/silccore/silcpacket.c.
5259 * Fixed buffer overflow in silc_parse_nickname in the file
5260 lib/silcutil/silcutil.c.
5262 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * make install generates new server keys only if there is not
5267 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5270 Added check that if the NOREPLY is set then we will not send
5271 the away message. This avoids infinite loop of away messages
5272 if both clients are away. The affected file is
5273 lib/silcclient/client_prvmsg.c.
5275 * Fixed client crash if /NICK was given without arguments.
5276 Affected file lib/silcclient/command.c.
5278 * Server does not send the invite list in INVITE command back
5279 to the client if the list was not altered. Added this notion
5280 to the protocol spec as well. Affected file silcd/command.c.
5282 Fixed possible crash in INVITE command by checking the
5283 value of silc_server_get_client_route command.
5285 * Fixed the INVITE notify type handling. The arguments are now
5286 taken in correct order and client does not crash. The affected
5287 file is irssi/src/silc/core/silc-channels.c.
5289 Removed the "Inviting xxx to channel" message from the
5290 client library away and let the application handle it.
5291 Affected file lib/silcclient/command.c. Added that message
5292 to Irssi SILC client's message formats.
5294 * Fixed CMODE command crash in client. It now checks the
5295 amount of arguments correctly and does not crash. The affected
5296 file is lib/silcclient/command.c.
5298 * Do not create new channel automatically in silc_channels_join
5299 but check whether the channel by that name already exists.
5300 Affected file irssi/silc/core/silc-channels.c.
5302 * Do not send the SERVER_SIGNOFF to router if the disconnected
5303 entity was the router. Affected file silcd/server.c.
5305 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5306 SILC client as it was missing from there.
5308 Added the handling of the KICK notify to the Irssi SILC client
5309 as it was missing. Added "you have been kicked" message to
5310 Irssi SILC client's message modules formats.
5312 Added the handing of the KILL notify to the Irssi SILC client
5313 as it was missing. Added the kill message module formats
5316 The affected file is irssi/src/silc/core/silc-channels.c.
5318 * The router did not save the channel mode the server announced.
5319 Affected file silcd/packet_receive.c.
5321 * Fixed a possible crash in INFO command in server. If the
5322 server did not provide the server info it crashed. Affected
5323 file silcd/command.c.
5325 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Fixed the GETKEY command in the server to check also the
5328 global list. Otherwise the GETKEY would not work correctly
5329 in normal SILC server. Affected file silcd/command.c.
5331 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Fixed GETKEY crash, it crashed if the command did not succseed.
5335 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5338 is now real and not just an macro interface to GMP.
5340 Removed the entire GMP from the source tree and imported new
5341 NSS MPI library instead. Reason for removing GMP is that it is
5342 extremely large and compiles extremely slow. The NSS MPI
5343 is only a few files and compiles in less than 10 seconds.
5344 The speed is also about the same as GMP. The MPI is imported
5345 to lib/silcmath/mpi.
5347 If the system has GMP installed we will still use the GMP.
5348 If it is not then the NSS MPI will be compiled.
5350 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Merged a long nickname (127 characters long) crash bugfix from
5353 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5355 * Merged a freed memory reference bugfix from Irssi CVS tree.
5356 Affected file irssi/src/core/commands.c.
5358 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Added the server's public key sving and verification to the
5361 server when performing the SKE. This was missing and the
5362 remote server's (or router's) public key was accepted without
5363 checking whether we have it previously or trust it at all.
5364 Affected file silcd/protocol.c.
5366 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Check in the silc_server_timeout_remote if protocol is active
5369 and make sure that the protocol's final callback is called so
5370 that all memory if freed. Affected file silcd/server.c.
5372 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * silc_server_whois_send_reply crashed the server if the nickname
5375 was 127 characters long. Affected file silcd/command.c.
5377 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Added sanity check to the silc_server_new_client. If the hostname
5380 is provided inside username then check that the provided hostname
5381 really is the same as the resolved one. If the hostname was not
5382 resolved then check it from the public key. Affected file is
5383 silcd/packet_receive.c.
5385 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5386 if the server disconnected us and the connection is not valid
5387 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5389 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5390 the library to the lib/silcutil/silcutil.[ch].
5392 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Close log file after open. Affected file
5395 lib/silcutil/silclog.c.
5397 * Check whether sock == NULL in silc_client_send_packet and return
5398 if it is. Affected file lib/silcclient/silcclient.c.
5400 * Check rec->entry == NULL in the Irssi SILC Client before
5401 sending the channel message. Affecte file is
5402 irssi/src/silc/core/silc-servers.c.
5404 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Merged a splitted window bugfix from Irssi CVS tree. The
5407 affected file is irssi/src/fe-text/textbuffer-view.c.
5409 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5410 It did not print nickname.
5412 * Improved the distributions system a bit.
5414 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5417 irssi/src/fe-text/gui-window.c.
5419 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5420 to in-active server. The affected file is
5421 irssi/src/silc/core/client_ops.c.
5423 * Resolve the client in USERS command reply if the entry does
5424 not have username resolved. The affected file is
5425 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5426 command to WHOIS command to really resolve stuff. The USERS
5427 is not used any more in any critical section so WHOIS can
5428 be used even though it might be slower than IDENTIFY.
5430 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5433 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Changed the protocol API a bit more consistent in the
5436 lib/silccore/silcprotocol.[ch].
5438 * Changed the following headers to ROBODoc format:
5440 lib/silccore/silcpayload.h
5441 lib/silccore/silcprotocol.h
5442 lib/silccore/silcsockconn.h
5444 All core library headers are now formatted.
5446 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed a bug in Irssi SILC client; do not show that you are
5449 server/router operator if you really are not. Affected file is
5450 irssi/src/silc/core/client_ops.c.
5452 * Renamed silc_command_free_payload to silc_command_payload_free.
5453 Affected file lib/silccore/silccommand.h
5455 * Added silcmath.h to include the prototoypes of various routines
5456 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5459 * Changed the following headers to ROBODoc format:
5461 lib/silccore/silcchannel.h
5462 lib/silccore/silccommand.h
5463 lib/silccore/silcid.h
5464 lib/silccore/silcidcache.h
5465 lib/silccore/silcmode.h
5466 lib/silccore/silcnotify.h
5467 lib/silccore/silcpacket.h
5468 lib/silcmath/silcmath.h
5470 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Added checking to the server code not to start the server if
5473 ciphers and stuff are not configured properly. Affected files
5474 silcd/serverconfig.[h] and silcd/server.c.
5476 * Changed the layout of the header files of the public interfaces
5477 in the SILC libraries. The new layout supports ROBODoc
5478 documentation tool (and some others) so that it is easy to create
5479 a library reference manual. All the other headers and source
5480 code must still follow the CodingStyle document. Also source
5481 code must not include these ROBODoc stuffs, only the headers.
5482 Furthermore, all public interface headers must now be named
5483 by using `silc' prefix, example: silcapi.h, silccipher.h.
5484 Some files were renamed due to this. All the other headers
5485 must not be used as public interfaces. I will update the
5486 CodingStyle document later. Changed following headers, so far:
5488 lib/silcclient/silcapi.h
5489 lib/silccore/silcauth.h
5490 lib/silccore/silcprivate.h
5491 lib/silccrypt/silcdh.h
5493 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Removed silc_client_packet_send_flush from the client library
5498 as it is not needed. Affected file lib/silcclient/client.[ch].
5500 * Added printing of message of unresolved authentication method
5501 to the Irssi SILC client. Added it to the module formats.
5502 Removed the same message from the client library.
5504 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Added new distribution feature, DISTLABEL. Every distribution
5507 can define own preprocessor label that can be used in the
5508 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5509 file distributions, acconfig.h.pre and prepare.
5511 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added Makefile.defines_int to include the actual definitions
5514 for Makefile.defines.in. Tested the new distribution system,
5515 created distributions and tested installation.
5517 * Added AWAY message printing to the Irssi SILC client. Added
5518 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5520 * Added SCONNECT command to call the SILC's CONNECT command.
5521 Cannot use CONNECT directly since Irssi uses that internally.
5522 Affected file irssi/src/silc/core/silc-servers.c.
5524 Added ACTION local command. It is same as ME command but takes
5525 the channel as mandatory argument.
5527 Rewrote some of the Irssi's help files to suite for SILC
5530 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added Makefile.defines[.in] that should for now on be included
5533 in all Makefile.am file in the source tree. That file includes
5534 all common compilation definitions for SILC source tree.
5536 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Minor changes to the ./prepare script to change the package
5539 name according the distribution name to the configure.in.
5541 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Created new distribution system. Added file `distributions'
5544 that defines all the distributions that can be created out of
5545 the SILC source tree. The ./prepare script now reads that
5546 file to determine how to prepare the distributions. The
5547 first argument to the ./prepare is the name of the distribution
5548 and second is the version of the distribution. If given
5549 without arguments it creates the default (toolkit) distribution
5550 with the default version (defined in ./prepare).
5552 All Makefile.am files that are subject to the distributions
5553 are now named as Makefile.am.pre. These are ./Makefile.am
5554 and lib/Makefile.am. Others may be changed later.
5556 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Added invite list, ban list, some key management and connection
5559 error message printing to module formats in the Irssi SILC client.
5561 * Added new silc_client_set_away_message to set the away message
5562 that is back to the person who sent private message. The
5563 affected file lib/silcclient/silcapi.h and the
5564 lib/silcclient/client_prvmsg.c.
5566 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Fixed the private message sending in the Irssi SILC client,
5569 added local command KEY to the Irssi SILC client.
5571 Added key management and key agreement message formats to the
5572 irssi/src/fe-common/silc/module-formats.[ch].
5574 Added USERS (alias WHO) printing, server/router operator
5575 indication and LIST command printing to the module formats.
5577 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Fixed channel joining notify handling, cumode notify handling
5580 from Irssi SILC client.
5582 * Added SILC specific module-formats to the Irssi SILC client so
5583 that SILC specific message hilighting, colors etc is possible.
5584 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5586 Added channel mode, channel user mode, actions, notices,
5587 whois and whowas printing to the the module-formats.c.
5589 * Fixed a bug in channel deletion in the server. The channel
5590 is not left to the cache even if the channel founder auth mode
5591 is set when there are no users anymore on the channel. Affected
5592 file silcd/server.c.
5594 * The silc_net_localhost now resolves the entire hostname including
5595 the domain name. Affected file lib/silcutil/silcnet.c.
5597 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Changed the ask_passphrase client operation to be ascynchronous.
5600 It has now a completion callback and a context that the
5601 application must call after it has got the passphrase from
5602 the user. Affected files lib/silcclient/silcapi.h,
5603 lib/silcclient/protocol.c, lib/silcclient/command.c and
5606 Added SilcAskPassphrase callback that the application calls
5607 to deliver the passphrase to the library.
5609 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5610 The public key verification and especially a certificate
5611 verification is asynchronous procedure.
5613 Added new SILC_SKE_STATUS_PENDING status to indicate the
5614 request is pending and a callback will be called to finalize
5617 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5618 indicate that remote end did not send its public key (or
5619 certificate), even though we require it. Added check for this
5620 condition in the SKE. This was a security bug, now fixed.
5622 Defined new SilcSKEVerifyCbCompletion callback that is called
5623 when the verification process is completed.
5625 The affected files lib/silcske/silcske_status.h and
5626 lib/silcske/silcske.[ch].
5628 * Changed the verify_public_key client operation to be async
5629 as well. Defined SilcVerifyPublicKey callback that is used to
5630 indicate the success of the public key verification process.
5632 Changed the server and client to use the new async client
5635 * Changed the Irssi SILC client's internal scheduler to be called
5636 twice as many times as it used to be. As a result the client
5637 should be a bit faster now. Affected file is
5638 irssi/src/silc/core/silc-core.c.
5640 * Added support to Irssi SILC client of asynchronous public key
5641 verification and passphrase inquiry. Affected file is
5642 irssi/src/silc/core/silc-core.c.
5644 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Do not say "You have left channel %s" in client library.
5647 Moved it to the application. Affected files are
5648 lib/silcclient/command.c and silc/client_ops.c.
5650 * Fixed silc_client_get_clients. Command context was not
5651 duplicated and was freed memory in the callback. Affected
5652 file lib/silcclient/idlist.c.
5654 * Do not say "you are now talking..." on JOIN command in the
5655 client library. The appliation must handle it.
5657 * Do not say ".. changed topic to" in command reply in the
5658 client libary. The application must handle it.
5660 * Fixed TOPIC command sending in the client library.
5662 * Fixed a memory leak in silc_client_command_free in the file
5663 lib/silcclient/command.c.
5665 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Imported a modified version of Irssi client to the source tree.
5668 The Irssi will be used to create a new client called
5669 Irssi SILC. Imported to irssi/.
5671 Added silc_core_init_finish function to the Irssi. Affected
5672 file irssi/configure.in.
5674 A lot changes in the Makefile.ams around the irssi tree.
5676 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Do not rehash if the new size is same as the old size of the
5679 hash table, in the silc_hash_table_rehash*. The affected file
5680 lib/silcutil/silchashtable.c.
5682 * Replaced hash_table_del_by_context calls from the server
5683 (when channel->user_list and client->channels) to the
5684 hash_table_del as it is sufficient and faster.
5686 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Added silc_hash_table_list, silc_hash_table_get and the
5689 SilcHashTableList structure to provide an alternative way to
5690 traverse the hash table. The affected files are
5691 lib/silcutil/silchashtable.[ch].
5693 * Changed the server's idlist routines to use the hash table
5694 routines to optimize the code.
5696 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Replaced the client entry's `channel' list and channel entry's
5699 `user_list' list to hash tables for optimized lookup. Changed
5700 the code to use the hash table interface around the code.
5701 Affected file lib/silcd/idlist.[ch].
5703 * Added `auto_rehash' boolean argument to the function
5704 silc_hash_table_alloc to indicate whether the hash table should
5705 auto-rehash when it thinks is appropriate time. It will
5706 increase the hash table size if the there is twice as much
5707 entries in the table than the size of the table, and will
5708 decrease the size if there are twice as less entries than
5709 the size of the table.
5711 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5715 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * silc_idcache_purge_by_context deletes the entry now by context
5718 as it is supposed to do. Affected file lib/silccore/idcache.c.
5720 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5721 client is not anymore valid (WHOWAS givens the info) and not
5722 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5724 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Removed the `data' and `data_len' arguments from the ID Cache
5727 interfaces and added `name' argument. ID Cache does not handle
5728 anymore the binary data only a names associated with given ID.
5730 * When hashing a Client ID with silc_hash_id the entire ID is
5731 not hashed anymore, instead only the hash of the Client ID is
5732 hashed. This way we can access the Client ID from the cache
5733 with Client ID but with the hash of the ID (which is a hash of
5734 the nickname) as well without any difference in performance.
5736 Added also silc_idcache_find_by_id_one_ext to do one on one
5737 searching when we have the actual ID. Added also function
5738 silc_hash_client_id_compare. The affected files are
5739 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5741 * When hashing the name associated with a ID it is always done
5742 in lowercase. This way we can access the cache without worrying
5743 about case-sensitivity, even though, for example nicknames are
5746 * Fixed a bug in server with channel message sending. It put
5747 wrong ID type as destination ID. The affected file
5748 silcd/packet_send.c.
5750 * silc_idcache_del_by_context now deletes from all hash tables
5751 by context. Affected file lib/silccore/idcache.c.
5753 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Changed the client library to use the new ID Cache interface.
5756 Changes around the source tree.
5758 * Added silc_hash_table_rehash_ext to rehash with specific
5759 hash function. Affected file lib/silcutil/silchashtable.[ch].
5761 * Added silc_hash_string_compare to compare two strings in the
5762 hash table. Affected file lib/silcutil/silcutil.[ch].
5764 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Added new function silc_idcache_del_by_context into the
5767 lib/silccore/idcache.[ch].
5769 * Changed the server's ID list routines to use the new ID Cache
5770 interface. Changes around the source tree.
5772 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added silc_hash_table_del[_by_context]_ext functions in to the
5775 lib/silcutil/silchashtable.[ch].
5777 Removed silc_hash_table_find_all* routines and added new
5778 silc_hash_table_find_foreach to replace them.
5780 Added silc_hash_table_replace_ext function as extended
5781 replacing function. Separated the simple hash table interface
5782 from the extended hash table interface in the file
5783 lib/silcutil/silchashtable.h.
5785 * Fixed minor bugs and changed it to use some of the new
5786 hash table functions in lib/silccore/idcache.c
5788 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added new function silc_hash_table_find_all to return all keys
5791 in the hash table by the specified key. As the hash table is
5792 collision resistant it also makes it possible to have several
5793 duplicate keys in the hash table. This function may be used to
5794 find all of the keys from the hash.
5796 Added user_context arguments to the SilcHashFunction,
5797 SilcHashCompare and SilcHashDestructor to deliver user specified
5800 Added new fuctions silc_hash_table_find[_all]_ext to do
5801 extended lookup with specified hash and compare functions and
5802 specified user contexts.
5804 Added new function silc_hash_table_add_ext to add the key
5805 with specified hash function and user context.
5807 Added new function silc_hash_table_foreach to traverse all
5808 entrys in the hash table. Added SilcHashForeach callback
5811 Added new function silc_hash_table_del_by_context to delete
5812 the entry only if the context associated with the key matches.
5814 Affected files are lib/silcutil/silchashtable.[ch].
5816 * Removed silc_hash_[server/client/channel]_id and added just
5817 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5818 silc_hash_id_compare to compare two ID's using as the hash table
5819 comparison function. Added also silc_hash_data to hash
5820 binary data and silc_hash_data_compare to compare it.
5822 * Removed silc_idlist_find_client_by_hash as it is not needed
5823 anymore. Affected file silcd/idlist.[ch].
5825 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5826 to use internally the SilcHashTable. The new ID Cache is a lot
5827 faster than the old one. Some of the ID Cache interface was also
5828 rewritten and obsolete and stupid functions were removed.
5830 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added entry_count field to the SilcHashTable to keep the number
5833 of the entries in the table. Implemented the function
5834 silc_hash_table_rehash. Added new function
5835 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5837 Fixed a minor bug in silc_hash_table_free.
5839 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5840 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5841 into the lib/silcutil/silcutil.[ch].
5843 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Implemented a collision resistant hash table into the
5846 lib/silcutil/silchashtable[ch]. See the header and the source
5847 for the SilcHashTable API.
5849 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Merged dotconf version 1.0.2 into lib/dotconf.
5853 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Do not compile anything in lib/silcsim/* if the SIM support
5856 is not enabled. The tree should now compile without problems
5859 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Compiled the SILC under cygwin. Compiled and tested briefly
5862 without problems. More tests needed. The SIMs didn't compile
5865 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5867 * Fixed possible crash in silc_get_username in the
5868 lib/silcutil/silcutil.c.
5870 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Fixed a va_arg in silc/client_ops.c.
5874 * Oops, RC5 routines were named AES and caused some problems
5875 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5877 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added new SilcIDIP structure into the lib/silccore/id.h and
5880 replaced the old `ip' fields from all SILC ID's to that type.
5881 This is a step towards IPv6 support.
5883 The silc_id_get_len takes now the ID as an extra argument.
5884 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5885 both IPv4 and IPv6 based ID's.
5887 The affected files are lib/silccore/id.[ch] and other files
5888 around the tree using these routines.
5890 * Removed the ID length arguments in server from various
5891 silc_server_send_notify_* routines -> they are not needed
5894 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Fixed memory leak in silc_encode_pem_file in the file
5897 lib/silcutil/silcutil.c.
5899 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Check minor version as well in the SKE. Affected files are
5902 silcd/protocol.c and lib/silcclient/protocol.c.
5904 * Added --identifier option to the server so that an identifier
5905 can be when creating the public key for the server. Affected
5906 file is silcd/silcd.c.
5908 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5909 lib/silccrypt/silcpkcs.c.
5911 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Register default ciphers and stuff when using -C option with
5914 the server. Affected file sildc/silcd.c.
5916 * Put back the servers public key filename format, it is better
5917 than the new one. For now, the client keys are saved with the
5918 new filename format. The affected file silc/client_ops.c.
5920 * Implemented the Cipher API for the rest of the ciphers that
5921 did not implement it or implemented it the wrong way.
5923 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Register default ciphers and stuff when using the -S option
5926 in the client. Affected file silc/silc.c. Same also when
5927 creating new key pair with -C option.
5929 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Fixed the silc_verify_public_key client operation function to
5932 save the public keys differently. The fingerprint is now
5933 used as filename and not the hostname. This way also the
5934 client keys are saved uniquely and not with hostnames. The
5935 affected file is silc/client_ops.c.
5937 * Trimmed the silc_hash_fingerprint function to remove extra
5938 whitespaces from the end of the fingerprint. The affected
5939 file is lib/silccrypt/silchash.c.
5943 * Added silc_cipher_register_default function to register all
5944 default ciphers. It can be used when configuration files
5945 does not exist and the application does not want any specific
5946 ciphers in any specific order.
5948 The SilcDList is now used as silc_cipher_list dynamically
5949 allocated cipher list. Removed the static list all together
5950 and now all ciphers must be allocated to the dynamic list.
5951 The silc_cipher_alloc routine was changed to check only the
5954 All silc_cipher_* routines that used to return int returns
5957 The affected files lib/silccrypt/silccrypt.[ch].
5959 * The same thing was done to silc_hash_* as for silc_cipher_*
5960 routines. Affected files lib/silccrypt/silchash.[ch].
5962 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5963 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5964 Added also silc_pkcs_[un]register[_default] functions.
5965 Removed the data_context from the PKCS API.
5967 * Added silc_hmac_register_default function to register default
5968 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5969 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5970 to unregister all hmacs at once.
5972 * Register the default ciphers, hash functions, PKCSs and HMACs
5973 if client's configuration file does not exist. The affected
5976 * The client did not load the hash functions from the SIM
5977 modules at all. Added support for this. Affected file is
5978 silc/clientconfig.c.
5980 * When decoding public key with silc_pkcs_public_key_decode, check
5981 the supported algorithm only if PKCS are registered. Affected
5982 file lib/silccrypt/silcpkcs.c. The same was done with the
5983 silc_pkcs_private_key_decode.
5985 * Fixed the SILC List routines to keep the list always in order.
5986 It used to change the list's order when traversing the list but
5987 not it preserves the order. Affected file lib/trq/silclist.h.
5989 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added the client library to use the SilcSocketConnection's
5992 reference counter (by silc_socket_dup) to prevent the bug that
5993 the socket object may be freed underneath async operation.
5995 * The name resolv library checking fixes in the configure.in.pre.
5998 * Created new version of the protocol drafts for future
5999 development. The -03 drafts are the ones that will be changed
6000 in the trunk now and the -02 will remain as they are.
6002 * Send list of CUMODE notifys to the router when announcing
6003 the channel users to the router. Affected file silcd/server.c.
6004 If the router receiving channel founder CUMODE for a channel
6005 that already has channel founder it will send CUMODE notify
6006 to the sender to remove the channel founder rights from the
6007 announced client. Affected file silcd/packet_receive.c.
6009 * The CUMODE notify may now use Server ID as well as the entity
6010 who changes the mode. Updated protocool specs.
6012 * Updated INSTALL and README files.
6014 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * New web pages in the http://silc.pspt.fi. The pages was
6021 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Implemented the [DenyConnectin] config section in the server.
6024 Added silc_server_config_denied_conn to check whether incoming
6025 connection is denied. Affected file silcd/serverconfig.[ch].
6027 * Do not check the ports when checking the incoming configuration
6028 data if the port is 0, meaning any. Affected file is
6029 silcd/serverconfig.c.
6031 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Fixed buffer overflow in silc_string_compare in the file
6034 lib/silcutil/silcutil.c.
6036 * Fixed double free in silc_server_command_leave in the file
6039 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Fixed the version checking in the server. Affected file is
6044 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Fixed the configuration data fetching when accepting new
6047 connections in the server. Affected file silcd/server.c.
6049 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added `sender_entry' argument to the function
6052 silc_server_packet_relay_to_channel so that we can check
6053 whether some destination actually belongs to the same route
6054 the sender belongs (ie, we must not resend the packet to the
6055 sender). Affected file silcd/packet_send.[ch].
6057 * Added `servername' field to the SilcClientEntry in the server
6058 to hold the name of the server where client is from. Affected
6059 file is silcd/idlist.h.
6061 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Moved the channel message encrypting in the router betwen
6064 router connections from silc_server_channel_message to the
6065 silc_server_packet_relay_to_channel since we want to check
6066 whether we have anybody channel before encrypting anything.
6067 Affected files silcd/packet_[receive/send].c.
6069 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Fixed the [AdminConnection] server config section to support
6072 multiple entries. Affected file silcd/serverconfig.c.
6074 * Added support into the server to check the validity of the
6075 incoming connection before executing any KE or authentication
6078 * The connection configuration is now saved to the KE and
6079 connection auth protocol contexts and not fetched anymore in
6080 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6082 * The local hosts listenning address and port is also resolved
6083 now when starting the server. We want to have the socket object
6084 to include the real address and port for the listener. Added
6085 new function silc_net_check_local_by_sock into the files
6086 lib/silcutil/silcnet.[ch].
6088 * Fixed a broadcast bug in server -> do not broadcast if we
6091 * Fixed a routing bug. Do not route broadcast packets ever.
6092 Broadcast packets must be processed always and not routed since
6093 they may be destined to some other host than yourself and thus
6094 would get routed without no good reason. Affected file is
6097 * Added function silc_server_config_is_primary_route to check
6098 whether primary router connection has been configured (a router
6099 configuration that we are initiating). If there is not, we
6100 will assume that there is only two routers in the SILC network
6101 and we will use the incoming router connection as our primary
6102 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6104 * Changed the order of the broadcasting. Broadcast _after_ the
6105 packet has been processed not before. Affected file is
6108 * Fixed a [ClientConnection] parsing bug. The port was never
6109 parsed correctly thus resulting to port 0. Affected file
6110 silcd/serverconfig.c.
6112 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6113 argument and did not set the broadcast packet flag. Affected
6114 file silcd/packet_send.c. Fixed same bug in the function
6115 silc_server_send_notify as well.
6117 * If we receive NEW_ID packet for our own ID in the server, ignore
6120 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Removed the nickname from the Private Message Payload.
6125 Updated the code and the protocol specs.
6127 * Updated protocol specs for submitting to the IETF.
6129 * Tweaked the Random Number Generator a bit. Affected file
6130 lib/silccrypt/silcrng.c. Exported a new function
6131 silc_rng_[global]_add_noise which can be used to add more
6134 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Do not parse packets with different timeout when protocol
6137 is active -> may cause problem with rekey. Affected file
6140 * When server receives signoff notify it must not create
6141 new channel key if the client is on any channels since the
6142 sender of the signoff notify will create it.
6144 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added printing of error messages during SKE protocol from the
6147 failure packet sent by server during SKE. Affected file
6150 * Removed the client's failure_callback handling with timeout
6151 and handle it immediately when received.
6153 * The SKE library returned wrong type in SUCCESS and FAILURE
6154 packets. They must be 32 bit MSB not 16 bit MSB.
6156 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Ok, rewrote the logic of the re-key and now it seems to work.
6159 I tested it on high traffic with frequent re-keys without
6160 problems. Added hmac_receive (and renamed hmac to hmac_send)
6161 in SilcClientConnection in lib/silcclient/client.h and
6162 in SilcIDListData in silcd/idlist.h. Also, removed the
6163 SilcPacketParserContext's cipher and hmac fields as they are
6164 not needed anymore and actually caused some problems when
6165 the ciphers and hmac's changed underneath the packet parser.
6167 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * If re-key protocol is active then process the incoming packets
6170 synchronously since we must assure that icoming packets encrypted
6171 with the old key is processed before the new keys is set to
6172 use. This is true other packets than for REKEY packets.
6173 Affected file silcd/server.c. The same was done to client library
6174 as well, affected file lib/silcclient/client.c.
6176 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Fixed bug in client and server to accept the force send if
6179 the packet is send from silc_[server/client]_packet_process
6180 function. Otherwise the packets are never delivered, oops.
6182 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Disable force sending of packets when REKEY protocol is active.
6185 We must assure that no packet is sent directly when rekey is
6186 performed. All packets must be sent through packet queue.
6187 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6188 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6189 function is silc_[server/client]_packet_send_real to check
6192 * Replaced the SIM paths from example config files to
6193 /usr/local/modules. Also, make install creates now
6194 /usr/local/silc/logs directory to hold all the SILC server
6197 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Made the configure.in.pre work on Solaris. Patch by salo.
6201 * Made all ciphers compatible with non-x86 machines. Defined
6202 CBC mode macros into lib/silccrypt/ciphers_def.h.
6204 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Fixed the make install.
6208 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * When MAC computation fails the silc_packet_decrypt returned 0
6211 even though it was supposed to return -1. Fixed this. The
6212 affected file is lib/silccore/silcpacket.c.
6214 * Do not replace the config files in /etc/silc (in make install)
6215 if they already exist. Affected file ./Makefile.am.
6217 * Do not send re-key packets immediately but through packet queue.
6218 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6220 * Changed silc_net_check_host_by_sock to return FALSE if the
6221 IP/DNS could not be resolved. Though, it returns the IP address
6222 now even if it could not resolve it (but returns also FALSE).
6223 Affected file lib/silcutil/silcnet.[ch].
6225 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added silc_pkcs_decode_identifier to decode the public key's
6228 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6229 Added also silc_pkcs_free_identifier. Added also new context
6230 SilcPublicKeyIdentifier.
6232 * Added -S option to the silc client. It is used to dump the
6233 contents of the specified public key file.
6235 * Changed the PKCS api to return the public key length when
6236 setting the public key.
6238 * Fixed a fatal bug in the public and private key file loading.
6239 Affected file lib/silccrypt/silcpkcs.c.
6241 * Execute the packet parsing for client with zero (0) timeout
6242 if the protocol is active. Affected file silcd/server.c.
6244 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Made the key generation options to the silcd program. Added
6247 -C option, equivalent to client's option.
6249 * Added new [ServerKeys] config section to the server. It
6250 configures the server's public and private key.
6252 * Defined generic Public Key Payload into the protocol
6253 specification to send specific type of public keys and
6256 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6257 public key or certificate.
6259 * Implemented the GETKEY command to the server and to the
6260 client library and on user interface.
6262 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Made preliminary `make install' work.
6266 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Added SilcServerRekey context into silcd/idlist.h.
6270 * Added the PFS support as defined in the specification to the
6271 SKE protocol. Affected files lib/silcske/*.c.
6273 * Added `ske_group' field to the SilcServerRekey context to hold
6274 the number of the SKE group that is used with PFS in re-key.
6275 Affected file silcd/idlist.h.
6277 * Added PFS re-key support to the server. Affected file is
6280 * Added silc_protocol_cancel to cancel execution of the next
6281 state of the protocol. Affected file is
6282 lib/silccore/silcprotocol.[ch].
6284 * Added the re-key support with and without PFS to the client
6285 library. Re-key is performed once in an hour, by default.
6287 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6288 Added silc_client_rekey_callback and silc_client_rekey_final.
6289 Affected files are lib/silcclient/protocol.[ch] and
6290 lib/silcclient/client.[ch].
6292 * Removed the `hmac_key' and `hmac_key_len' fields from the
6293 SilcClientConnection structure; not needed. Affected file is
6294 lib/silcclient/client.h.
6298 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6300 * Do not ask whether user wants to use the negotiated private key
6301 for private messages, just use it. Affected file is
6302 silc/local_command.c.
6304 * Added `send_enc_key' and `enc_key_len' fields to the
6305 SilcIDListData structure since they are needed in the re-key
6306 phase. Affected file is silcd/idlist.[ch].
6308 * Implemented the simple re-key protocol into the server.
6309 Affected files silcd/server.c and silcd/protocol.[ch]. The
6310 re-key will be performed once in an hour, by default.
6312 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6313 Added silc_server_rekey, silc_server_rekey_callback and
6314 silc_server_rekey_final.
6316 * Removed Tunneled flag from the protocol. Updated the code
6317 and the specifications.
6319 * Adde `pfs' field to the SilcIDListData to indicate whether
6320 the PFS is to be performed in the re-key. Affected file is
6323 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6326 int64 of at least the xintXX size. If void * is less that 4
6327 bytes uint32 * will be used. Defined bool as boolean.
6329 * Changed _ALL_ unsigned long and unsigned int to uint32,
6330 unsgined short to uint16 in the source tree.
6332 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6333 not handle clients that has entry->data.registered == FALSE.
6334 They are not in the network anymore. Affected file is
6337 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Implemented the sending of the SERVER_SIGNOFF notify in the
6340 server. Affected file is silcd/server.c.
6342 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6343 Added also silc_notify_payload_encode_args into the
6344 lib/silccore/silcnotify.[ch].
6346 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6347 Affected file silcd/packet_receive.c.
6349 * Implemented the SERVER_SIGNOFF notify handling in the client
6350 library. Affected file lib/silcclient/client_notify.c. Also,
6351 implemnted the printing of the SERVER_SIGNOFF info to the
6352 application. Affected file silc/client_ops.c.
6354 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6355 if the deleting was successful. Affected file silcd/idlist.[ch].
6357 * Added support for public key authentication in the connection
6358 authentication protocol in the client library. Affected file
6359 lib/silcclient/protocol.c.
6361 * Changed the server's silc_idlist_get_clients_by_* interface
6362 to support already allocated array so that new entries may be
6363 added to pre-allocated array. Affected file silcd/idlist.[ch].
6364 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6365 and command replies.
6367 * All command reply functions in the server now calls the
6368 pending command callback even if error occured. This way the
6369 error will be delivered to the client as well. Affected files
6370 silcd/command.c and silcd/command_reply.c.
6372 * Fixed INFO command to return local server's info if no server
6373 was provided. Affected file lib/silcclient/command.c.
6375 * Removed RESTART command for good. Updated the code and the
6378 * Rewrote parts of the task system. It is a bit simpler now.
6379 Removed unsued task priorities. The affected files are
6380 lib/silcutil/silctask.[ch].
6382 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Moved the USERS printing from the library to the application.
6385 Affected files lib/silcclient/command.c and silc/client_ops.c.
6387 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Added channel key re-key support. The re-key is perfomed
6392 only by the router and is done once in an hour. Added `rekey'
6393 field to the SilcChannelEntry in the server. Affected files
6394 silcd/server.c and silcd/idlist.h.
6396 * Added silc_task_unregister_by_context into the file
6397 lib/silcutil/silctask.[ch].
6399 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Added SILC_UMODE_GONE mode to indicate when the client is not
6402 present in the SILC network. Added also support to the local
6403 command AWAY that will set this mode. Added support of showing
6404 "xxx is gone" in WHOIS command. The USERS command shows the
6405 gone status as well.
6407 * Fixed setting server and router operator privileges in the
6408 server's UMODE command. Affected file silcd/command.c.
6410 * Merged the SKE KE1 and KE2 payloads into one payload. The
6411 new KE payload is equivalent to the old KE2 payload.
6413 Cleaned up the SKE Start Payload parsing. It now uses the
6414 simple buffer unformatting to do the parsing. A lot faster
6417 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6418 to the SKE that is used to indicate whether both of the SKE
6419 parties should perform authentication. By default only the
6420 responder performs authentication. By setting this flag also
6421 the initiator must do authentication. By default it is unset
6422 since in normal SKE case, client to server connection, only
6423 the responder should do authentication. When doing SKE between
6424 two clients both should perform authentication. Updated the
6425 code and the protocol specs.
6427 * A little fix to IDENTIFY command in the server. Search the
6428 client first by hash not nickname. Affected file is
6431 * Fixed the silc_client_close_connection to support closing
6432 the client to client connections wihtout deleting too much
6433 data. Affected file lib/silcclient/client.c.
6435 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6436 are received if protocol used to be active but is not anymore
6437 the application would crash due to NULL pointer dereference.
6438 Affected files silcd/server.c and lib/silcclient/client.c.
6440 * Added `hash' field to the SilcClientConnection to include
6441 the hash function negotiated in the SKE protocol.
6443 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6444 to set the channel founder authentication data. A client can
6445 claim the founder rights later by providing the authentication
6446 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6447 This way the channel founder can regain the channel founder
6448 privileges even it is left the channel. This works only on
6449 local server and the client must be connected to the same
6450 server to be able to regain the founder rights. Updated the
6451 protocol specs accordingly.
6453 Added support to the CMODE command in the client to set the
6454 founder auth data. Read the README to see how to set it.
6456 Added support to the CUMODE command to claim the founder
6457 rights. Read the README to see how to do it.
6459 Added support for the founder authentication to the Channel
6460 Entry in the server. Affected file silcd/idlist.h.
6462 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6463 server's CMODE command. Affected file silcd/command.c.
6465 * Added the following new functions into lib/silccore/silcauth.[ch]:
6466 silc_auth_get_method and silc_auth_get_data.
6468 * The server now saves the remote hosts public key to the
6469 SilcIDListData pointer. Affected file silcd/protocol.c.
6471 * The normal server now does not remove the channel entry from
6472 the cache if the founder authentication data is set. It used
6473 to remove it if the founder was the last one on the channel on
6474 the server and left the channel. The auth data is saved and
6475 if the channel is re-joined later the old entry is used with
6476 the old auth data. Affected files silcd/command_reply.c and
6479 * Removed the `pkcs' field from the SilcIDListData structure
6480 in the server; it is not used. Affected file silcd/idlist.h.
6482 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Fixed packet processing on slow links. Partial packets were
6485 never re-processed because the incoming data buffer was cleared
6486 by the application. Application must not directly clear the
6487 sock->inbuf, the packet processing routines handle it. Fixed
6488 this in client library and in server.
6490 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Fixed the WHOIS and IDENTIFY send reply function to really
6493 check whether to send list or just one entry. Affected file
6496 * Cleaned up the LEAVE command's channel key distribution. The
6497 affected file silcd/command.c.
6499 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6500 can enforce the channel mode as well. In that case the ID
6501 includes the ID of the server. The code now enforces the
6502 mode change if the router have different mode than the server.
6504 * The notify client operation with CMODE_CHANGE notify can now
6505 return NULL client_entry pointer if the CMODE was not changed
6506 by client. Application must check for this.
6508 * Added <Server ID> argument to INFO command to support server
6509 info fetching by Server ID.
6511 * Added silc_server_announce_get_channel_users to get assembled
6512 packets of channel users of the specified channel. Affected
6513 file silcd/server.[ch].
6515 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6516 was freed underneath the ID Cache.
6518 * Re-announce clients when the server received CHANNEL_CHANGE
6519 notify from the router. Affected file silcd/packet_send.c.
6521 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6524 crashed since it did not handle the fact that there is no cipher
6525 called "3" and didn't check the error condition. Now fixed.
6527 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6528 flag. It can be used to send message requests.
6530 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Implemented the RESTART command in the client.
6534 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6535 notice type messages. Added notice printing to the user
6538 * The channel keys are not re-generated if the channel's mode
6539 is PRIVKEY, ie private key on the channel exists. Affected
6540 files silcd/server.c and silcd/command.c.
6542 * Fixed a little bug in channel message delivery when channel
6543 private keys are set in the server. Affected file is
6544 silcd/packet_send.c.
6546 * Changed the setting on channel->on_channel = TRUE from the
6547 silc_client_save_channel_key to the JOIN command reply. The
6548 key payload is not received if the private channel key is set.
6549 Affected file lib/silcclient/command_reply.c and the
6550 lib/silcclient/client_channel.c.
6552 * When the CMODE_CHANGE notify is sent and the channel private
6553 key mode is removed the channel key must be re-generated in
6554 other cells as well. Added this support for the router in the
6555 silcd/packet_receive.c.
6557 * Added new local command NOTICE to send notice message on
6558 channel. Affected file silc/local_command.[ch].
6560 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Added new local command ME to the client. It is used to send
6563 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6564 some action. Affected file silc/local_command.[ch].
6566 * Changed channel_message and private_message client operations
6567 to deliver the message flags to the application. Added also
6568 the `flags' arguments to the silc_client_send_channel_message
6569 and silc_client_send_private_message functions. Affected file
6572 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Redefined the Private Message Payload to support private message
6575 keys and to support the new private message flags. Updated
6576 the protocol specs. Flags makes it possible to have for example
6577 CTCP style messages.
6579 * Added new type SilcPrivateMessagePayload and defined an API
6580 for it in the lib/silcclient/silcprivate.[ch].
6582 * Tested private message private keys successfully. Tested the
6583 private message key set, unset and list commands with the new
6586 * Redefined the Channel Message Payload to include the channel
6587 message flags (equal with private message flags) to support
6588 for example CTCP style messages.
6590 * Defined some of the message (for channel and private message)
6591 flags. Updated the protocol specs and added the flags to the
6592 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6594 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * Added SilcKeyAgreementStatus type to the key agreement routines
6597 to indicate the current status and error if one occured.
6598 The status types are defined in the lib/silcclient/silcapi.h.
6600 * Added new local command KEY that is used to set and unset private
6601 keys for channels, set and unset private keys for private messages
6602 with remote clients and to send key agreement requests and
6603 negotiate the key agreement protocol with remote client. The
6604 key agreement is supported only to negotiate private message keys,
6605 it currently cannot be used to negotiate private keys for channels,
6606 as it is not convenient for that purpose.
6608 * Fixed a minor pending callback setting bug in the function
6609 silc_client_get_client_by_id_resolve, now the function works.
6610 Affected file lib/silcclient/idlist.c.
6612 * Added function silc_net_get_local_port to get local bound
6613 port by socket. Added to lib/silcutil/silcnet.[ch].
6615 * Added `sockets' and `sockets_count' fields to the SilcClient
6616 object. They hold the sockets of the listenning sockets in
6617 the client. Listenning sockets may be for example the key
6618 agreement server. Affected file lib/silcclient/client.[ch].
6619 Added functions the silc_client_add_socket and the
6620 silc_client_del_socket. They are exported to the application
6623 * Added ~./silc/clientkeys to support other client's public keys.
6625 * Renamed verify_server_key client operation to verify_public_key
6626 and added one argument to indicate the type of the connection
6627 (server, client etc.).
6629 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Added silc_server_connection_auth_request to handle the
6632 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6633 silcd/packet_receive.[ch].
6635 * Added silc_server_send_connection_auth_request into the
6636 silcd/packet_send.c to send the connection auth request packet.
6638 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6641 * Fixed the public key authentication in responder side in the
6642 server. The `auth_data' pointer includes the SilcPublicKey
6643 not the path to the public key. Affected file silcd/protocol.c.
6645 * Implemented the public key authentication in the initiator side
6646 in the server. Affected file silcd/protocol.c.
6648 * Removed the [RedirectClient] config section from the server
6649 configuration. Is not needed and I don't want to implement it.
6651 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Cleaned up the CMODE command in the server. It now works
6654 correctly and supports all the modes defined in the protocol.
6655 Affected file is silcd/command.c.
6657 * Added `hmac_name' field to the SilcChannelEntry in the server
6658 to hold the default HMAC of the channel. It can be set when
6659 creating the channel (with JOIN command). Affected files
6662 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6663 type to indicate the change of the current cipher and hmac
6664 on the channel. Client can safely ignore the <cipher> argument
6665 (if it chooses to do so) since the CHANNEL_KEY packet will
6666 force the channel key change anyway. The <hmac> argument is
6667 important since the client is responsible of setting the new
6668 HMAC and the hmac key into use.
6670 * Fixed the CMODE command in the client library as well.
6672 * Tested CMODE command in router environment successfully.
6674 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Show the version of the remote client (or server) when connecting
6677 to the server. It is logged to the log file. Affected file
6678 is silcd/protocol.c.
6680 * Fixed the KILLED notify handling in the client library. The
6681 client must be removed from all channels when receiving the
6684 Also, do not remove the client entry when giving the KILL
6685 command but when the KILLED notify is received.
6687 * Removed silc_idlist_find_client_by_nickname from the server.
6688 Not needed anymore. Affected files silcd/idlist.[ch].
6690 * Implemented the CHANNEL_CHANGE notify type handling to the
6691 server. Affected file silcd/server.c.
6695 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added silc_server_send_notify_invite to send the INVITE
6698 notify between routers.
6700 * Implemented the INVITE command correctly to the server.
6702 * Implemented the INVITE notify type handling in the server.
6704 * Implemented the INVITE command to the client library and on the
6707 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added function silc_server_get_client_resolve to find the
6710 client entry by ID from all ID lists and then resolve it
6711 (using WHOIS) if it cannot be found. Affected file is
6714 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Implemented the BAN command to the client library.
6718 * The JOIN command in the server now checks the invite list
6721 * Changed the silc_command_reply_payload_encode_va and the
6722 silc_command_payload_encode_va to support that if argument is
6723 NULL it ignores and checks the next argument. Affected file
6724 lib/silccore/silccommand.c.
6726 * Added silc_server_send_notify_ban to send the BAN notify
6727 type between routers.
6729 * Chaned the silc_notify_payload_encode to support that if
6730 argument is NULL it ignores and checks the next argument.
6731 Affected file lib/silccore/silcnotify.c.
6733 * Tested ban lists in router environment successfully.
6735 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Implemented BAN command to the server, in silcd/command.[ch].
6739 * Removed the BAN and INVITE_LIST modes from the CMODE command
6742 * Added function silc_string_match to regex match two strings.
6743 Affected files lib/silcutil/silcutil.[ch].
6745 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Redefined parts of the SilcChannelEntry in the server to support
6748 the new ban and invite lists.
6750 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Redefined the INVITE command. The same command can be used to
6753 invite individuals to the channel but also to manage the invite
6754 list of the channel (to add to and remove from the invite list).
6755 Updated the protocol specs.
6757 * Added new command SILC_COMMAND_BAN that can be used to manage
6758 the ban list of the channel. Updated the protocol specs.
6760 * Removed the channel modes: the SILC_CMODE_BAN and the
6761 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6762 in the CMODE command. The equivalent features are now available
6763 using INVITE and BAN commands. Updated the protocol specs.
6765 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6766 in the network about change in the current ban list. The notify
6767 type is not used by the client.
6769 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6770 support the invite lists.
6772 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Added new function silc_string_regexify that converts string
6775 including wildcard characters into regex string that can
6776 be used by the GNU regex library. Added into the file
6777 lib/silcutil/silcutil.[ch].
6779 Added silc_string_regex_combine to combine to regex strings
6780 into one so that they can be used as one regex string by
6781 the GNU regex library. Added into the file
6782 lib/silcutil/silcutil.[ch].
6784 Added silc_string_regex_match to match two strings. It returns
6785 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6787 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Imported GNU regex to the soruce tree into lib/contrib.
6790 Fixed some compiler warning from the regex.c.
6792 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Fixed MOTD command in the server to work in router environment.
6796 * Fixed the MOTD command in the client library to support
6797 the server argument in the command.
6799 * Added `nickname_len' argument to the silc_idlist_add_client
6800 in the server, as the `nickname' argument may be binary data
6803 * Added silc_idlist_get_channels to return all channels from
6806 * Implemented LIST command to the server. Affected file is
6809 * Implemented the LIST command to the client library and on the
6812 * Added [<user count>] argument to the LIST command reply.
6813 With private channels the user count is not shown.
6815 * Updated TODO and README.
6817 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * The client entry's data.registered must be TRUE even with
6820 global client entry on global client list. The data.registered
6821 is used to check whether the client is anymore in the network,
6822 for example with WHOWAS command so it must be valid.
6824 * Fixed the WHOWAS command in the server. It now actually works
6825 in router environment. Added function into silcd/command_reply.c
6826 silc_server_command_reply_whowas_save.
6828 * Added silc_idlist_purge function to the silcd/idlist.c
6829 to periodically purge the ID Cache.
6831 * Fixed INFO command in the server. It works now in router
6832 environment. Added <server name> argument to the INFO command
6833 reply. Updated the protocol specs.
6835 * Fixed minor bug in silc_idcache_purge to not purge if the
6836 expire value is zero.
6838 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6839 they were buggy because of the WHOWAS information.
6841 * Fixed local command MSG to handle the async resolving of
6842 the remote client properly. It used to fail the first MSG.
6843 Affected file silc/local_command.c.
6845 * Added `data_len' field to SilcIDCache context.
6847 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Update TODO. Todo in commands in the server.
6851 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6854 used by routers as broadcast packet to inform other routers
6855 about the changed user mode.
6857 Implemented the notify handling in the server. Affected file is
6858 silcd/packet_receive.c. Added the function
6859 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6861 * Added new generic Channel Payload and deprecated the New Channel
6862 Payload. The New Channel Payload is now the generic Channel
6865 * Added new argument `mode' to the silc_server_send_new_channel
6866 as it is required in the Channel Payload now.
6868 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6869 and created a new and real SilChannelPayload to represent the
6870 new generic Channel Payload. Implemented the encode/decode
6871 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6873 * Added silc_server_get_client_channel_list to return the list
6874 of channels the client has joined for WHOIS command reply.
6875 Affected file silcd/server.[ch].
6877 * Implemented the channel list sending in the WHOIS command reply
6878 in server and in the client.
6880 Implemented the channel list displaying on the user interface
6881 as well. Affected file silc/client_ops.c.
6883 * Added silc_channel_payload_parse_list to parse list of Channel
6884 Payloads. It returns SilcDList list of SilcChannelPayloads.
6885 Client for example can use this function to parse the list of
6886 channels it receives in the WHOIS command reply. The caller
6887 must free the list by calling silc_channel_payload_list_free.
6888 Affected files lib/silccore/silcchannel.[ch].
6890 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Added one new argument <user mode> to the WHOIS command reply
6893 to return the mode of the user in SILC. Updated the protocol
6896 Implemented it to the server and client.
6898 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Fixed the mode printing on the user interface on joining.
6901 Affected file silc/client_ops.c.
6903 * Implemented the UMODE command and user modes in general to the
6904 client library and to the user interface.
6906 * Implemented the UMODE command to the server.
6908 * The server now sends UNKNOWN_COMMAND error status if client sends
6909 unknown command. Affected file silcd/command.c.
6911 * All server commands now handle the command identifier the right
6912 way when sending the command reply to the client. The client can
6913 use to identify the command replies with the identifier.
6915 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Added silc_server_get_client_route to resolve the route to
6918 the client indicated by the client ID. Affected file is
6921 * Added silc_server_relay_packet as general function to relay
6922 packet to arbitrary destination. This deprecates functions
6923 like _send_private_message_key, _relay_notify etc. Affected
6924 file is silcd/packet_send.[ch].
6926 Removed silc_server_send_key_agreement,
6927 silc_server_send_private_message_key and
6928 silc_server_packet_relay_notify functions from the file
6929 silcd/packet_send.[ch].
6933 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6934 server. Affected file silcd/packet_receive.[ch].
6936 * Implemented the KILL command to the client. Implemented the
6937 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6938 Affected files lib/silcclient/command[_reply].c and
6939 lib/silcclient/client_notify.c. Implemented the KILL notify
6940 printing in the user inteface.
6942 * Fixed a lot silc_parse_nick memory leaks from the client
6943 library in the file lib/silcclient/command.c.
6945 * Changed the silc_server_send_notify_on_channels's `sender'
6946 argument from SilcSocketConnection to SilcClientEntry to
6947 check the sender as entry and not as connection object and not
6948 to send to the client provided as argument. The affected file
6949 is silcd/packet_send.[ch].
6951 * The notify packets that are destined directly to the client used
6952 to not to be processed by the server. Now changed that and the
6953 server processes all notify packets. After relaying the packet
6954 to the client the notify packet is processed in the server.
6956 * The silc_server_free_client_data now checks whether there is
6957 pending outgoing traffic for the client and purges the data to
6958 the network before removing the client entry.
6960 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6963 an client is killed from the SILC Network. Updated the protocol
6966 Added new function silc_server_send_notify_killed to the
6967 silcd/packet_send.[ch].
6969 * Added function silc_server_packet_relay_notify to relay notify
6970 packets that are destined directly to a client. In this case
6971 the server does not process the notify packets but merely relays
6972 it to the client. Affected file silcd/packet_send.[ch].
6974 Added also silc_server_packet_process_relay_notify to check
6975 whereto relay the notify. Affected file is
6976 silcd/packet_receive.[ch].
6978 * Implemented the KILL command to the server.
6982 * Added the backup schema desgined last fall to the protocol
6983 specs for everyone to see. The specification is in the
6984 *-spec-xx.txt draft and the packet type definitions for the
6985 backup routers is in *-pp-xx.txt draft. Thusly, added also
6986 new packet type SILC_PACKET_CELL_ROUTERS.
6988 * A big security problem in the implementation discovered. The
6989 signoff of an client did not cause new channel key generation
6990 which it of course should've done. The channel keys must be
6991 always re-generated when client leaves (or signoffs) the channel.
6992 The silc_server_remove_from_channels funtion now handles
6993 the channel key re-generation.
6995 * Added `sender' argument to the silc_server_send_notify_on_channels
6996 to not to send the client provided as argument. Affected file
6997 silcd/packet_send.[ch].
6999 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Implemented OPER and SILCOPER commands into the server and
7004 * Added silc_auth_verify and silc_auth_verify_data to verify
7005 the authentication directly from the authentication payload.
7006 It supports verifying both passphrase and public key based
7007 authentication. Affected file lib/silccore/silcauth.[ch].
7009 * Added `hash' field to the SilcIDListData structure. It is the
7010 hash negotiated in the SKE protocol. Affected file is
7013 * Slight redesigning of the SilcAuthPayload handling routines.
7014 Do not send SilcPKCS but SilcPublicKey as argument.
7016 * Implemented the public key authentication support to the
7017 serverconfig. The public key is loaded from the provided path
7018 and saved as authentication data to void * pointer. Thus,
7019 changed the unsigned char *auth_data to void *auth_data;
7021 * Fixed SHUTDOWN command to send the reply before the server
7022 is shutdown. :) Affected file silcd/command.c.
7024 * Fixed fatal bug in CONNECT command. The hostname was invalid
7025 memory and server crashed. Affected file silcd/command.c.
7027 * Fixed fatal bug in CLOSE command. The server_entry became
7028 invalid but was referenced later in the command. Affected file
7031 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Fixed fatal bug in failure packet handling. Server ignored
7034 the failure and thus crashed when it came.
7038 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7041 that the command may be executed only once in (about) 2 seconds.
7042 The old SILC_CF_LAG flag is same but allows command bursts up
7043 to five before limiting.
7045 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7046 server code. Various commands now includes the CF_LAG_STRICT
7047 flag to disallow any kind of miss-use of the command.
7049 * Fixed the silc_buffer_unformat to not to allocate any data
7050 if the length of the data is zero. It used to allocate the
7051 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7053 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Changed the format of AdminConnection configuration section
7056 in the server. Added username of the admin to the format.
7057 Affected files silcd/serverconfig.[ch].
7059 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7060 to return admin configuration data by host, username and/or
7063 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Implemented WHOWAS command to the server. Added the functions:
7067 silc_server_command_whowas_parse,
7068 silc_server_command_whowas_send_reply,
7069 silc_server_command_whowas_from_client and
7070 silc_server_command_whowas_from_server
7072 * Added <Client ID> argument to the WHOWAS command reply. Updated
7073 the protocol specs accordingly.
7075 * Implemented WHOWAS command and command_reply to the client
7078 Implemented the WHOWAS printing on the user interface.
7080 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * Added new argument to the WHOWAS command reply, the real name.
7083 It is an optional argument. Updated the protocol specs.
7085 * Added SilcIDCacheDestructor callback that is registered when
7086 the SilcIDCache is allocated. The callback is called when
7087 an cache entry in the ID Cache expires, or is purged from the
7088 cache. Added into lib/silccore/idcache.[ch].
7090 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7091 to destruct the client entries when the cache entry expires.
7092 Other ID Cache's in server and in the client library ignores
7095 * If the ID Cache entry's `expire' field is zero then the entry
7096 never expires. Added boolean `expire' argument to the
7097 silc_idcache_add function in the lib/silccore/idcache.[ch].
7098 If it is TRUE the default expiry value is used.
7100 * Added silc_server_free_client_data_timeout that is registered
7101 when client disconnects. By default for 5 minutes we preserve
7102 the client entry for history - for WHOWAS command.
7104 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Added support to the server to enforce that commands are not
7107 executed more than once in 2 seconds. If server receives
7108 commands from client more frequently, timeout is registered
7109 to process the commands. Affected file silcd/command.c.
7110 Added new function silc_server_command_process_timeout.
7112 * Changed NICK_NOTIFY handling in client library to check that
7113 if the client's nickname was changed, so there is no need to
7114 resolve anything from the server.
7116 * Removed error printing from the WHOIS and IDENTIFY commands.
7117 If error occurs then it is ignored silently in the client library.
7118 The application, however, may map the received error to
7119 human readable error string. The application currently maps
7120 the NO_SUCH_NICKNAME error to string.
7122 * Made the command status message public to the application. Moved
7123 them from lib/silcclient/command_reply.c to
7124 lib/silcclient/command_reply.h. The application can map the
7125 received command status to the string with the
7126 silc_client_command_status_message function.
7128 * Added check to the server to check that client's ID is same
7129 as the Source ID in the packet the client sent. They must
7132 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Added dist-bzip hook to the Makefile.am to make bzip2
7135 compressed distributions.
7137 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Server now enforces the maximum length for the nickname and
7140 the channel as protocol specification dictates. 128 bytes for
7141 nickname and 256 bytes for channel name.
7143 * Moved the WHOIS printing to the application. The client libary
7144 does not print out the WHOIS information anymore, the application
7145 must do it. Renamed silc_client_command_reply_whois_print to
7146 the silc_client_command_reply_whois_save.
7148 The client's idle time is also sent to the application now, and
7149 the idle is shown on screen.
7151 * Added silc_client_command_reply_identify_save to save the
7152 received IDENTIFY entries.
7154 * Do not check for channel private keys in message sending and
7155 reception if the channel does not have the PRIVKEY mode set.
7156 Affected file lib/silclient/client_channel.c.
7158 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7161 just surfaced after chaning the JOIN procedure.
7163 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * Added silc_client_get_clients_by_list to get client entries
7166 from Client ID list, that is returned for example by JOIN
7167 and USERS command replies. The application should use this
7168 function for example when JOIN command reply is received to
7169 resolve the clients already on the channel (library does not
7170 do that anymore as USERS command reply is not used in the JOIN
7171 procedure anymore). Affected files lib/silcclient/silcapi.h and
7172 lib/silcclient/idlist.c.
7174 * JOIN command reply and USERS command reply returns now SilcBuffer
7175 pointers instead of unsigned char pointers when returning
7176 the client list and mode list.
7178 * Added <Client ID> argument to the JOIN command reply, mainly
7179 for the server to identify for which client the command was
7180 originally sent. Updated protocol specs accordingly.
7182 * Added SilcDlist private_key pointer to the SilcChannelEntry
7183 in the client to support the channel private keys. Affected
7184 file is lib/silcclient/idlist.h.
7186 * Added SilcChannelPrivateKey argument to the function
7187 silc_client_send_channel_message so that application can choose
7188 to use specific private ke if it wants to. If it is not provided,
7189 the normal channel key is used, unless private keys are set.
7190 In this case the first (key that was added first) is used
7191 as the encryption key.
7193 * Implemented the support for channel private key handling.
7194 Implemented the following functions:
7196 silc_client_add_channel_private_key,
7197 silc_client_del_channel_private_keys,
7198 silc_client_del_channel_private_key,
7199 silc_client_list_channel_private_keys and
7200 silc_client_free_channel_private_keys
7202 Affected file lib/silcclient/client_channel.c.
7204 * Added the support for the private keys in the channel message
7205 sending and encryption and in the message reception and
7206 decryption. Affected funtions are
7207 silc_client_send_channel_message and silc_client_channel_message.
7209 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7211 * Added SKE's key verify callback to the client library's
7212 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7214 * Removed the statement that server (or router) must send USERS
7215 command reply when joining to the channel so that the client
7216 knows who are on the channel. Instead, the client list and
7217 client's mode list is now sent in the JOIN command reply to the
7218 client who joined channel. This is better solution.
7220 * Added function silc_server_get_users_on_channel and function
7221 silc_server_save_users_on_channel to the silcd/server.[ch].
7223 * Removed function silc_server_command_send_users from the
7226 * Do not show topic on the client library anymore. The topic is
7227 sent in the command reply notify to the application and the
7228 application must show the topic now.
7230 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7232 * Added client searching by nickname hash into the IDENTIFY and
7233 WHOIS commands in the server as they were clearly missing from
7234 them. Affected file is silcd/command.c.
7236 * Fixed a bug in private message receiving in the client library.
7237 The remote ID was freed and it wasn't supposed, now it is
7240 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Minor fix to the channel payload; allocate the data area, as it
7243 needs to be of specific length.
7245 * If the key agreement port is zero then the operating
7246 system will define the bound port. Affected files are
7247 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7249 * Added new function silc_channel_payload_decrypt into the file
7250 lib/silccore/silcchannel.[ch].
7252 * Moved the channel message etc, check from silc_packet_decrypt
7253 to applications. The library calls now a generic
7254 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7255 when the packet is either normal or special. This was done to
7256 allow more wide range of checking that was not allowed when
7257 the code was in library. Now applications can do virtually any
7258 checks to the packet and return to the library the decision how
7259 the packet should be processed. Affected files are
7260 lib/silccore/silcpacket.[ch].
7262 Added silc_server_packet_decrypt_check to the server and
7263 silc_client_packet_decrypt_check to the client library.
7265 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7266 to send with specified source and destination information.
7268 * Channel message delivery between routers was broken after the
7269 channel key distribution was fixed earlier. The channel key
7270 was used be to distributed to other routers as well which is not
7271 allowed by the protocol. Now this is fixed and channel keys
7272 really are cell specific and the channel message delivery between
7273 routers comply with the protocol specification.
7275 * Fixed various commands in server to check also the global list
7276 for the channel entry and not just the local list. The affected
7277 file silcd/command.c.
7279 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added assert()s to buffer formatting and unformatting routines
7282 to assert (if --enable-debug) when error occurs. Affected
7283 file: lib/silcutil/silcbuffmt.c.
7285 * Changed to auto-reconnect to check whether the remote host is
7286 router and register the re-connect timeout if it is. It used
7287 to check that whether we are normal server, but router must do
7288 auto-reconnect with another router as well. Affected file
7291 * Removed the [<key len>] option from CMODE command as the cipher
7292 name decides the key length, nowadays. See the defined ciphers
7293 from the protocol specification.
7295 * Added [<hmac>] option to the CMODE command to define the HMAC
7296 for the channel. Added SILC_CMODE_HMAC channel mode.
7298 * Added [<hmac>] option for the JOIN command so that user can
7299 select which HMAC is used to compute the MACs of the channel
7302 * Added Hmac field to the Channel Message Payload. The integrity
7303 of plaintext channel messages are now protected by computing
7304 MAC of the message and attaching the MAC to the payload. The
7305 MAC is encrypted. Now, it is clear that this causes some
7306 overhead to the size of the packet but rationale for this is that
7307 now the receiver can verify whether the channel message decrypted
7308 correctly and also when private keys are set for the channel the
7309 receiver can decrypt the packet with several keys and check from
7310 the MAC which key decrypted the message correctly.
7312 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7313 lib/silccrypt/silccipher.[ch].
7315 * Added silc_hash_len to return the digest length into the
7316 lib/silcrypt/silchash.[ch].
7318 * Rewrote parts of Silc Channel Payload interface in the
7319 lib/silccore/silcchannel.[ch]. The encode function now also
7320 encrypts the packet and parse function decrypts it.
7322 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Fixed a minor formatting bug in the SKE's key material processing.
7325 It actually might have processed the keys wrong way resulting
7328 * Redefined the mandatory HMAC algorithms and added new algorithms.
7329 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7330 and hmac-md5 truncated to 96 bits. The mandatory is now
7331 hmac-sha1-96. Rest are optional (including the one that used
7332 to be mandatory). Rationale for this is that the truncated HMAC
7333 length is sufficient from security point of view and can actually
7334 make the attack against the HMAC harder. Also, the truncated
7335 HMAC causes less overhead to the packets. See the RFC2104 for
7338 * Added new [hmac] configuration section. The SKE used to use
7339 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7340 is of course wrong. The official names that must be proposed in
7341 the SKE are the ones defined in the protocol specification
7342 (hmac-sha1-96 for example). The user can configure any hmac
7343 using any hash function configured in the [hash] section. At
7344 least, the mandatory must be configured.
7346 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7348 * Added HMAC list to the SKE proposal list. It has now both
7349 hash algorithm list and HMAC list. This makes the protocol
7350 incompatible with previous versions. The SKE now seems to work
7351 the way it is supposed to work, for the first time actually.
7353 * Defined plain Hash algorithms to the protocol specification.
7356 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * Implemented support for key agreement packets into the server.
7359 Added functions silc_server_key_agreement and
7360 silc_server_send_key_agreement. Other than these functions,
7361 server has nothing to do with this packet.
7363 * Added support for private message key packets into the server.
7364 Added functions silc_server_private_message_key and
7365 silc_server_send_private_message_key.
7369 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7370 called in the protocol's final callback instead in the END
7371 protocol state. This makes a little more sense and in the same
7372 time in client we can use the same protocol routines for normal
7373 key exchange and to key agreement packet handling as well.
7375 * Added to both client's and server's KE protocol context the
7376 SilcSKEKeyMaterial pointer to save the key material. We will
7377 bring the key material to the protocol's final callback by doing
7378 this. The final callback must free the key material.
7380 * Added SKE's packet_send callback into client's KE protocol
7381 context so that the caller can choose what packet sending function
7382 is used. This way we can use different packet sending when
7383 doing normal SKE when doing key agreement packet handling (in
7384 the key agreement packet handling we do not want to encrypt
7387 * Implemented the responder side of the key agreement routines
7388 in the client. The client can now bind to specified port and
7389 accept incoming key negotiation. The key material is passed
7390 to the application after the protocol is over.
7392 * Implemented the processing of incoming Key Agreement packet
7393 in the client. Added function silc_client_key_agreement to
7396 * Implemented the intiator side of the key agreement routines
7397 in the client. The client can now initiate key agreement with
7398 another remote client. The key material is passed to the
7399 application after the protocol is over.
7401 * Created client_keyagr.c to include all the key agreement
7404 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7405 SILC_TASK_CALLBACK except that it is not static.
7407 * Created client_notify.c and moved the Notify packet handling
7408 from the client.[ch] into that file.
7410 * Created client_prvmsg.c and moved all private message and
7411 private message key routines from the client.[ch] into that file.
7413 * Create client_channel.c and moved all channel message and
7414 channel private key routines from the client.[ch] into that file.
7416 * Changed silc_client_get_client_by_id_resolve to resolve with
7417 WHOIS command instead of IDENTIFY command, in the file
7418 lib/silclient/idlist.c.
7420 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Implemented the SKE's responder side to the Client library.
7424 * When FAILURE is received to the protocol do not trust it
7425 blindly. Register a timeout to wait whether the remote closes
7426 the connection as it should do it, only after that process the
7427 actual failure. This was changed to both client and server.
7429 * Added client_internal.h to include some of the structures
7430 there instead of client.h in lib/silcclient/.
7432 * Added function silc_task_unregister_by_callback to unregister
7433 timeouts by the callback function.
7435 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Some "Incomplete WHOIS info" errors has been appearing on the
7438 log files. Took away the entry->userinfo check from WHOIS
7439 reply sending. The entry->userinfo is now " " if client did not
7440 provide one. I thought this was fixed earlier but something
7441 is wrong still. Let's see if the error still appears.
7443 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Fixed a minor bug in the login when the channel key is
7446 re-generated in the server. It used to generate the key in
7447 wrong order and thus caused problems in the channel traffic.
7449 * Fixed a minor bug in channel key distsribution after
7450 KICK command. The key was not sent to the router even though
7453 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * Added silc_ske_process_key_material_data as generic routine
7456 to process any key material as the SILC protocol dictates. The
7457 function is used by the actual SKE library but can be used by
7458 applications as well. This relates to the private message keys
7459 and the channel private keys since they must be processed the
7460 same way the normal SILC session keys. The protocol dictates
7461 this. Affected files: lib/silcske/silcske.[ch].
7463 Added also silc_ske_free_key_material to free the
7464 SilcSKEKeyMaterial structure.
7466 * Defined silc_cipher_set_key function to set the key for
7467 cipher without using the object's method function. The affected
7468 files: lib/silccrypt/silccipher.[ch].
7470 * Implemented silc silc_client_add_private_message_key,
7471 silc_client_add_private_message_key_ske,
7472 silc_client_del_private_message_key,
7473 silc_client_list_private_message_keys and
7474 silc_client_free_private_message_keys functions in the
7477 Added functions silc_client_send_private_message_key to send
7478 the Private Message Key payload and silc_client_private_message_key
7479 to handle incoming Private Message Key payload.
7481 * Added Cipher field to the Private Message Key payload to set
7482 the cipher to be used. If ignored, the default cipher defined
7483 in the SILC protocol (aes-256-cbc) is used.
7485 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Removed lib/silcclient/ops.h file.
7489 Redefined parts of the SILC Client Library API. Created new
7490 file silcapi.h that deprecates the ops.h file and defines the
7491 published Client Library API. Defined also private message key
7492 API and channel private key API into the file.
7494 This is the file that the application must include from the
7495 SILC Client Library. Other files need not be included by
7496 the application anymore.
7498 * Added new key_agreement client operation callback and also
7499 defined the Key Agreement library API for the application.
7501 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7504 is used by clients to request key negotiation between another
7505 client in the SILC network. If the negotiation is started it
7506 is performed using the SKE protocol. The result of the
7507 negotiation, the secret key material, can be used for example
7508 as private message key.
7510 Implemented the Key Agreement payload into the files
7511 lib/silccore/silauth.[ch].
7513 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Redefined ciphers for the SILC protocol. Added some new ciphers
7516 and defined the key lengths for the algorithms. Changed the
7517 code accordingly. The default key length is now 256 bits.
7519 * Fixed SKE key distribution function silc_ske_process_key_material
7520 when the key length is more than 128 bits. The default key
7521 length in SILC is now 256 bits.
7523 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7524 to indicate unsupported algorithm.
7526 * Renamed rijndael.c to aes.c and all functions as well.
7528 * Fixed a long standing channel key setting bug in client library.
7529 Weird that it has never surfaced before.
7531 * Fixed bug in channel deletion. If the entire channel is removed
7532 then it must also delete the references of the channel entry
7533 from the client's channel list as the client's channel entry and
7534 the channel's client entry share same memory.
7536 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Implemented CONNECT and SHUTDOWN commands in the client.
7540 * Implemented CLOSE command to the client.
7542 * Added the function silc_idlist_find_server_by_name into the
7543 files silcd/idlist.[ch].
7545 Added the function silc_idlist_find_server_by_conn into the
7546 files silcd/idlist.[ch].
7548 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * DIE command was renamed to SHUTDOWN. Updated the both code
7553 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7554 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7556 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7559 * Added function silc_server_create_connection function to create
7560 connection to remote router. My server implementation actually
7561 does not allow router to connect to normal server (it expects
7562 that normal server always initiates the connection to the router)
7563 so the CONNECT command is only good for connecting to another
7566 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7568 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7569 or some other client was kicked from the channel.
7571 Implemented the handling of the notify type to both client
7574 Implemented silc_server_send_notify_kicked to send the KICKED
7575 notify. It is used to send it to the server's primary router.
7577 * Implemented the KICK command into server and client.
7579 * Added `query' argument to the silc_idlist_get_client function
7580 to indicate whether to query the client from server or not if
7583 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7584 to indicate that the client is not channel founder.
7588 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7590 * Removed the rng context from SilcPacketContext structure and
7591 changed that the packet routine uses the Global RNG API.
7593 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7595 * Added support for quit message that client can "leave" on the
7596 channel when it quits the SILC. It is ditributed inside the
7597 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7599 Added silc_server_free_client_data that will take the
7600 signoff message as argument.
7602 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7604 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Updated parts of the protocol specification to keep it up
7609 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7611 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7612 payloads in one packet.
7614 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7615 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7616 use now the new List flag.
7618 * Also deprecated the following packet types: REPLACE_ID,
7619 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7621 * Added list support for Notify packet in server.
7623 * Added silc_server_send_notify_channel_change to send the
7624 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7625 the silc_server_send_replace_id.
7627 * Added silc_server_send_notify_nick_change to send the
7628 NICK_CHANGE notify type. Deprecates the function
7629 silc_server_send_replace_id.
7631 * Added silc_server_send_notify_join to send the JOIN notify type.
7632 Deprecates the function silc_server_send_new_channel_user.
7634 * Added silc_server_send_notify_leave to send LEAVE notify type.
7635 Deprecates the function silc_server_send_remove_channel_user.
7637 * Added silc_server_send_notify_cmode and
7638 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7639 types. Deprecates the silc_server_send_set_mode function.
7641 * Added SERVER_SIGNOFF notify type to indicate that server has
7642 quit. This means that all clients on the channel from that
7643 server will drop. This can be also used when netsplit happens.
7645 Deprecated REMOVE_ID packet type since it is not needed anymore
7648 Added silc_server_send_notify_server_signoff to send the
7649 SERVER_SIGNOFF notify type. Deprecates the function
7650 silc_server_send_remove_id.
7652 Added also silc_server_send_notify_signoff to send the
7653 SIGNOFF notify type.
7655 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7656 SILC protocol from this day on. Changed the protocol
7657 specification as well.
7659 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7660 notify type. It is used between routers to notify about
7661 topic changes on a channel.
7663 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7666 * Partly updated the protocol specification to comply with the
7667 changes now made. It is still though a bit outdated.
7669 * The JOIN notify type now takes one extra argument <Channel ID>.
7670 The packet used to be destined to the channel but now the
7671 JOIN type may be sent as list thus it is impossible to
7672 destine it to any specific channel. By adding this argument
7673 it is again possible.
7675 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Added CREDITS file. The CHANGES and CREDITS file will appear
7678 in the distribution as well.
7680 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7683 types in the server's silcd/packet_receive.c.
7685 * Implemented CMODE and CUMODE to work in router environment.
7687 * Fixed minor encoding and decoding buglet from the
7688 lib/silccore/silcmode.c.
7690 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7693 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7695 * Changed all SilcConfigServer* and silc_config_server* to
7696 SilcServerConfig* and silc_server_config*, respectively.
7699 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7701 * Associated the ID (client or server ID) to the Authentication
7702 Payload to avoid any possibility of forging. Updated the
7703 protocol specification and the code accordingly.
7705 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * The RSA key length is now save to the RsaKey context in the
7708 key generation process in lib/silccrypt/rsa.c. The key length
7709 is now used to figure out the maximum size of the block allowed
7710 to be encrypted/signed.
7712 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7713 is equivalent to the silc_mp_mp2bin but does not allocate any
7716 * Changed silc_mp_mp2bin API to take length argument. If it is
7717 non-zero then the buffer is allocated that large. If zero, then
7718 the size is approximated using silc_mp_sizeinbase, which however
7721 * Created Global RNG API which is global RNG that application can
7722 initialize. After initializing, any routine anywhere in the
7723 code (including library) can use RNG without allocating a new
7724 RNG object. This was done to allow this sort of use of the
7725 RNG in code that has no chance to allocate RNG object. All
7726 applications currently allocate this and many routines in the
7727 library use this. Affected file lib/silccrypt/silcrng.[ch].
7729 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7730 it to use the Global RNG API.
7732 * Defined Authentication Payload into protocol specification that
7733 is used during SILC session to authenticate entities. It is
7734 used for example by client to authenticate itself to the server
7735 to obtain server operator privileges.
7737 Implemented this payload into the lib/silccore/silcauth.[ch].
7738 Implemented also routines for public key based authentication
7739 as the new protocol specification dictates.
7741 Moved definitions of different authentication methods from
7742 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7744 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7745 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7746 silc_pkcs_verify_with_hash functions into the file
7747 lib/silccrypt/silcpkcs.[ch].
7749 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7751 * The client entry's userinfo pointer must be always valid.
7752 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7753 will fail since it requires the userinfo. Now, the userinfo
7754 is allocated as "" if actual userinfo does not exist. Actually,
7755 it must exist and it is totally Ok to drop client connections
7756 that does not announce the userinfo. However, we will make
7757 this workaround for now.
7759 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7760 to return the remote port by socket.
7762 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7765 SILC_SERVER_PENDING_EXEC and added an new macro
7766 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7767 data or when error occurs while processing the pending command.
7769 Added new argument `destructor' into silc_server_command_pending
7770 and to the SilcServerCommandPending object. This destructor is
7771 now called after calling the pending callback or if error occurs
7772 immediately. If error occurs the actual pending callback won't
7773 be called at all - only the destructor. The destructor may be
7774 NULL if destructor is not needed.
7776 All this applies for client library code as well. Similar
7777 changes were made there as well for the pending commands.
7779 In the client, the application must now allocate the
7780 SilcClientCommandContext with the silc_client_command_alloc
7783 * Added reference counter to the SilcServerCommandContext. Added
7784 function silc_server_command_alloc and silc_server_command_dup
7787 Same type of functions added to the client library for the same
7790 * Removed the cmd_ident from IDListData away since it is now
7791 global for all connections. It is the command identifier used
7792 in command sending and with pending commands. The affected file
7795 * Added reference counter to the SilcSocketConnection objecet to
7796 indicate the usage count of the object. The object won't be
7797 freed untill the reference counter hits zero. Currently only
7798 server uses this, and client ignores it. The client must be
7799 set to use this too later. The affected files are
7800 lib/silccore/silcsockconn.[ch]. Added also the function
7801 silc_socket_dup to increase the reference counter.
7803 This was mainly added because it is possible that the socket
7804 is removed underneath of pending command or other async
7805 operation. Now it won't be free'd and proper DISCONNECTING
7806 flags, etc. can be set to avoid sending data to connection that
7807 is not valid anymore.
7809 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7810 the connection. After that it sets SILC_SET_DISCONNECTED.
7811 It is, however, possible that the socket data is not still freed.
7812 The silc_server_packet_process now checks that data is not
7813 read or written to connection that is DISCONNECTED. The socket
7814 get's freed when the reference counter hits zero.
7816 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Changed the client operation API: channel_message operation's
7819 `sender' is now the client entry of the sender, not the nickname
7820 and the `channel' is the channel entry, not the channel name.
7822 In the private_message operation the `sender' is now also the
7823 client entry of the sender not the nickname.
7825 Affected file is lib/silcclient/ops.h and all applications
7826 using the client operations.
7828 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7830 * Moved the calling of ops->connect() from connect_to_server_final
7831 into receive_new_id functin since that is the point when the
7832 client is actually allowed to send traffic to network. The
7833 affected file is lib/silcclient/client.c.
7835 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7837 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7838 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7839 (if needs broadcasting) instead of broadcasting the packets one
7840 by one which would make a burst in the network traffic.
7842 * Added `broadcast' argument to the functions in silcd/server.[ch]
7843 silc_server_create_new_channel[_with_id] to indicate whether
7844 to send New Channel packet to primary router.
7846 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Added new function into the silcd/server.[ch] files:
7849 silc_server_create_new_channel_with_id to create new channel with
7850 already existing Channel ID.
7852 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7853 lib/silccore/silcpacket.h. This packet is used t send list of
7854 Set Mode payloads inside one packet. Server uses this to set
7855 the modes for the channels and clients on those channels, that it
7856 announced to the router when it connected to it. The protocol
7857 specification has been updated accordingly.
7859 * The silc_server_new_channel did not handle the packet coming
7860 from normal server as it normally does not send that. However,
7861 when it announces its channels it does send it. Implemented
7862 the support for that.
7864 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7865 into the file lib/silccore/id.h.
7867 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Fixed memory leaks in the functions silc_idlist_del_client,
7870 silc_idlist_del_channel and silc_idlist_del_server in the file
7871 silcd/idlist.c. All of those leaked like a sieve.
7873 * Fixed some small memory leaks in the client's function
7874 silc_client_notify_by_server.
7876 * Added functions into silcd/server.c: silc_server_announce_clients,
7877 silc_server_announce_channels and silc_server_announce_server.
7878 These functions are used by normal and router server to announce
7879 to its primary router about clients, channels and servers (when
7880 router) that we own. This is done after we've connected to the
7883 These functions effectively implements the following packet types:
7884 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7885 and SILC_PACKET_NEW_ID_LIST.
7887 * Added new functions into the silcd/packet_receive.[ch]:
7888 silc_server_new_id_list, silc_server_new_channel_list and
7889 silc_server_new_channel_user_list to handle the incoming
7890 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7892 * Added support of changing Channel ID in the function
7893 silc_server_replace_id. If the server that announces a channel
7894 to the router already exists in the router (with same name but
7895 with different Channel ID), router is responsible to send
7896 Replace ID packet to the server and force the server to change
7897 the Channel ID to the one router has.
7899 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7900 client that the Channel ID has been changed by the router. The
7901 normal server sends this to the client. Client must start using
7902 the new Channel ID as the channel's ID.
7904 Implemented handling of this new type into lib/silcclient/client.c
7905 into the function silc_client_notify_by_server.
7907 * Added new function silc_idlist_replace_channel_id into the files
7908 silcd/idlist.[ch] to replace the Channel ID.
7910 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7912 * Call silc_server_command_identify_check always when processing
7913 the IDENTIFY command in silcd/command.c
7915 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7917 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7918 send keepalive packets. The packet can be sent by clients,
7919 servers and routers.
7921 Added function silc_socket_set_heartbeat into the file
7922 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7923 If not set, the heartbeat is not performed. The actual
7924 heartbeat is implemented in the low level socket connection
7925 library. However, application is responsible of actually
7928 Added silc_server_send_heartbeat to send the actual heartbeat
7929 packet into silcd/packet_send.[ch]. Server now performs
7930 keepalive with all connections.
7932 * Added silc_task_get_first function into lib/silcutil/silctask.c
7933 to return the timeout task with shortest timeout. There was a bug
7934 in task unregistration that caused problems. TODO has been
7935 updated to include that task system must be rewritten.
7937 * The client library will now resolve the client information when
7938 receiving JOIN notify from server for client that we know but
7939 have incomplete information.
7941 * Rewrote parts of silc_server_remove_from_channels and
7942 silc_server_remove_from_one_channel as they did not remove the
7943 channel in some circumstances even though they should've.
7945 * Encryption problem encountered in server:
7947 The LEAVE command used to send the Channel Key packet to the
7948 router immediately after generating it. However, the code
7949 had earlier sent Remove Channel user packet but not immediately,
7950 ie. it was put to queue. The order of packets in the router
7951 was that Channel Key packet was first and Remove Channel User
7952 packet was second, even though they were encrypted in the
7953 reverse order. For this reason, MAC check failed. Now, this
7954 is fixed by not sending the Channel Key packet immediately but
7955 putting it to queue. However, this is more fundamental problem:
7956 packets that are in queue should actually not be encrypted
7957 because packets that are sent immediately gets encrypted
7958 actually with wrong IV (and thus MAC check fails). So, packets
7959 that are in queue should be encrypted when they are sent to
7960 the wire and not when they put to the queue.
7962 However, the problem is that the current system has not been
7963 designed to work that way. Instead, the packet is encrypted
7964 as soon as possible and left to the queue. The queue is then
7965 just purged into wire. There won't be any fixes for this
7966 any time soon. So, the current semantic for packet sending
7969 o If you send packet to remote host and do not force the send
7970 (the packet will be in queue) then all subsequent packets to the
7971 same remote host must also be put to the queue. Only after the
7972 queue has been purged is it safe again to force the packet
7975 o If you send all packets immediately then it safe to send
7976 any of subsequent packets through the queue, however, after
7977 the first packet is put to queue then any subsequent packets
7978 must also be put to the queue.
7980 Follow these rules and everything works fine.
7982 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7984 * Added new function silc_server_remove_clients_by_server to
7985 remove all client entries from ID list when the server connection
7986 is lost. In this case it is also important to invalidate all
7987 client entires as they hold the invalid server entry. This
7988 fixes fatal bug when server has lost connection and will reconnect
7991 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7993 * Made some sanity checks to silc_server_daemonise like to check
7994 whether the requested user and group actually exists.
7996 * Added sanity check to SKE's silc_ske_responder_finish to check
7997 that the public and private key actually is valid.
7999 * Invalidate the client's nickname when receiving Replace ID
8000 packet and the Client ID is being replaced. This means that the
8001 server will query the nickname if someone needs it (client)
8004 * Sort the ID Cache in client library when the ID Cache data
8005 has changed (needs sorting).
8007 * Do not allow for SILC client to create several connections to
8008 several servers. The client does not support windows right now
8009 and generating multiple connections causes weird behaviour.
8011 Irssi-silc client does support windows and can handle several
8012 connections without problems, see: www.irssi.org and SILC plugin.
8014 * Fixed some places where client was added to the IDList. The
8015 rule of thumb is following (in order to get everything right):
8016 If the client is directly connected local client then the
8017 `connection' argument must be set and `router' argument must be
8018 NULL to silc_idlist_add_client function. If the client is not
8019 directly connected client then the `router' argument must
8020 bet set and the `connection' argument must be NULL to the
8021 silc_idlist_add_client function.
8023 * The funtion silc_server_packet_send_local_channel actually did
8024 not check whether the client was locally connected or not. It
8025 does that now. Fixed a bug related to LEAVE command.
8027 * Fixed Remove Channel User payload parsing bug in server's
8028 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8030 * The server's silc_server_save_channel_key now checks also the
8031 global ID list for the channel as it might not be in the local
8032 list. Fixed a bug related to LEAVE command.
8034 * Is this the end of the [<unknown>] buglet that has been lurking
8035 around for a long time? A little for loop fix in server's
8036 silc_server_command_whois_parse that is used by both IDENTIFY
8037 and WHOIS command. At least, this was a clear bug and a cause
8038 of one type of [<unknown>] buglet.
8040 * WHOIS and IDENTIFY commands call the function
8041 silc_server_command_[whois/identify]_check function even if
8042 we are not router server.
8044 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Added --with-gmp configuration option. If set the GMP
8047 is always compiled in the SILC source tree. If not set then
8048 it is checked whether the system has the GMP3 installed. If
8049 it has then the GMP won't be compiled (the system's headers
8050 and library is used), if it doesn't have it then the GMP is
8051 compiled in the SILC source tree.
8053 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Changed RSA private exponent generation to what PKCS #1
8056 suggests. We try to find the smallest possible d by doing
8057 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8058 not security fix but optimization.
8060 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8062 * Added new config entry [Identity] to fork the server and run
8063 it as specific user and group. A patch from Bostik.
8065 * Imported Dotconf configuration library into lib/dotconf.
8066 This will be used to create the SILC configuration files later.
8067 It will appear in the distsribution after this commit.
8069 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8071 * A big code auditing weekend happening. Auditing code for
8072 obvious mistakes, bugs and errors. Also, removing any code
8075 Removed files for being obsolete:
8077 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8078 inline in the file lib/silcutil/silcbuffer.h)
8080 o lib/silcutil/silcbufutil.c (the header has inline versions)
8082 Changed code to fix possible error conditions:
8084 o The buffer formatting routines now check that the destination
8085 buffer really has enough space to add the data. This applies for
8086 both buffer formatting and unformatting
8087 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8088 unformatting was changed to accomodate following rules:
8089 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8090 sent to the function while XXX_*STRING will not allocate or copy
8091 the data into the buffer. Instead it sets the pointer from the
8092 buffer into the pointer sent as argument (XXX_*STRING used to
8093 require that the pointer must be allocated already). This change
8094 makes this whole thing a bit more consistent and more optimized
8095 (note that the data returned in the unformatting with XXX_*STRING
8096 must not be freed now). The routines return now -1 on error.
8098 o Tried to find all code that use buffer_format and buffer_unformat
8099 and added return value checking to prevent formatting and
8100 especially unformatting errors and possible subsequent fatal
8103 o Changed ske->x and ske->KEY to mallocated pointers in
8104 lib/silcske/silcske.h. Fixed possible data and memory leak.
8106 o Added return value checking to all *_parse* functions. Fixed
8107 many memory leaks as well.
8109 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8110 so that buffer overflows would not happen. All code now also
8111 checks the return value as it can fail.
8113 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Added reconnection support to server if the normal server looses
8116 its connection to the router (for example if router is rebooted).
8117 The server performs normal reconnection strategy implemented
8118 to the server. Affected file silcd/server.c.
8120 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Added new packet type SILC_PACKET_SET_MODE that is used to
8123 distribute the information about changed modes (for clients,
8124 channels and clients channel modes) to all routers in the
8125 network. Updated the protocol specification accordingly.
8127 Added functions into silcd/packet_send.c and
8128 silcd/packet_receive.c: silc_server_send_set_mode,
8129 silc_server_set_mode.
8131 Added new files silcmode.[ch] into lib/silccore that implements
8132 the encoding and decoding of Set Mode Payload. Added new type
8133 SilcSetModePayload. Moved the definitions of different modes
8134 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8136 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Oops, a little mistake in server's connection authentication
8139 protocol. The protocol is not ended with FAILURE but with
8140 SUCCESS if the authentication is Ok. :) Affected file is
8143 * Implemented NICK_CHANGE notify handling in server in the file
8144 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8145 the local clients on the channel. After the changing nickname
8146 in router environment snhould work and the [<unknown>] nickname
8147 should appear no more.
8149 The silc_server_replace_id function that receives the Replace ID
8150 payload now sends the NICK_CHANGE notify type also in the file
8151 silcd/packet_receive.c
8153 * Changed WHOIS and IDENTIFY command to support the maximum amount
8154 of arguments defined in protocol specs (3328 arguments). This
8155 fixed a bug that caused problems when there were more than three
8158 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * Added extra parameter, command identifier, to the
8161 silc_client_send_command so that explicit command identifier
8164 Changed that ID list routines uses specific command identifier
8165 when sending WHOIS/IDENTIFY requests to the server so that they
8166 can be identified when the reply comes back.
8168 Affected files lib/silcclient/command.[ch],
8169 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8171 * Added `sender' argument to silc_server_packet_send_to_channel
8172 to indicaet the sender who originally sent the packet to us
8173 that we are now re-sending. Ignored if NULL. Affected file
8174 silcd/packet_send.[ch].
8176 * Added some server statistics support in silcd/server_internal.h
8177 SilcServerStatistics structure and around the server code. Also
8178 send some nice statistics information when client is connecting
8181 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Fixed channel ID decoding in server's JOIN command reply in
8184 silcd/command_reply.c
8186 * Fixed braodcasting of replace ID payload to not to send it if
8187 we are standalone server in silcd/packet_receive.c.
8189 * Fixed all channel message sending routines to not to send
8190 packets to clients that has router set, since they are routed
8191 separately in the same function earlier. Affects file
8192 silcd/packet_send.c and all channel packet sending functions.
8194 * In USERS reply, res_argv[i] are not allocated, the table
8195 is allocated. Thus changed that free the table, not its
8198 * In server's whois_check and identify_check if the client is
8199 locally connected do not send any WHOIS commands - they are not
8202 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Fixed some minor bugs in client when sending WHOIS command. The
8205 arguments was in wrong order.
8207 * Removed statis function add_to_channel from server in
8208 silcd/command.c that was previously used with the joining but
8211 * Tested USERS command in router environment successfully with two
8212 routers, two servers and two clients.
8214 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Reorganized the USERS command and command reply in client library
8217 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8218 When the command is given by user we register a pending command
8219 callback that will reprocess the command after the reply has been
8220 received from the server. When reprocessing the packet we then
8221 display the information. Thus, the USERS information is displayed
8222 now in the command callback instead of in the command reply
8223 callback. The processing of the command is same as previously
8224 when server has sent the command reply in the JOINing process.
8226 * Added to USERS command in silcd/command_reply.c to join the client,
8227 we didn't use to know about, to the channel after we've created
8228 a client entry for it. Also, for clienet we did know already still
8229 check whether it is on the channel or not and add it if not.
8231 * Removed silc_server_command_join_notify as the function and its
8234 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8236 * Changed the client's pending command handling to the same as the
8237 server's pending command handling. It is also now possible to
8238 execute command reply functions from other command reply
8239 function as the function callbacks for commands and command
8240 replies are one and same. The pending commands are not static
8241 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8242 in client connection context. Thus, pending commands are server
8243 connection specific as it is convenient.
8245 Changed the function silc_client_command_pending and
8246 silc_client_command_pending_del and added new function
8247 silc_client_command_pending_check. Removed the
8248 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8251 * Added cmd_ident, current command identifier, to the client
8252 connection context in lib/silcclient/client.h to keep track on
8253 command identifiers used in command sending. Client's command reply
8254 function handling now supports the mandatory command identifiers.
8256 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8257 funtions in client to fully support pending command callbacks.
8259 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8260 as one of the arguments to the application in the command reply
8263 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8264 before first releasing SILC but came back. Now it is removed again
8265 and should come back nomore. The FORWARDED flag was used only
8266 by the JOINing procedure by forwarding the command packet to router.
8267 Now, the JOINing procedure has been changed to more generic (due
8268 to various router environment issues) and FORWARDED is not needed
8269 anymore for anything. The protocol specification is yet to be
8272 Now, removed silc_server_packet_forward from server and the flag
8273 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8275 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Renamed NAMES command to USERS command. The NAMES was named that
8278 due to historical reasons. Now it is renamed. Also, rewrote
8279 parts of the USERS command. The nickname list is not sent anymore
8280 by the server. Only Client ID and mode lists are sent in the USERS
8281 command. Changed this also to the protocol specification.
8283 The client now resolves the names and stuff after it receives
8284 the USERS list from the server when joining to the channel.
8286 * WHOIS and IDENTIFY commands has been changed to support multiple
8287 Client ID's per command. One can now search for multiple users
8288 in the network by sending only one WHOIS or IDENTIFY command.
8289 Changed the code and the protocol specifications.
8291 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8292 uses silc_server_command_whois_parse to parse the request. */
8294 * If normal server, do not parse the WHOIS and IDENTIFY requests
8295 before sending it to the router. Saves some time.
8297 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8299 * Fixed JOIN command on client library. Wrong number of arguments
8300 used to crash the client.
8302 * Added silc_server_channel_has_global function to check whether
8303 channel has global users or not.
8305 * Added silc_server_channel_has_local function to check whether channel
8306 has locally connected clients on the channel.
8308 * The silc_server_remove_from_one_channel now checks whether the
8309 channel has global users or not after given client was removed from
8310 the channel. It also checks whether the channel has local clients
8311 on the channel anymore. If it does not have then the channel entry
8312 is removed as it is not needed anymore.
8314 * The silc_server_notify now checks on JOIN notify whether the joining
8315 client is one of locally connected or global. If it is global then
8316 the channel has now global users on the channel and that is marked
8317 to the channel entry. Also, it now saves the global client to
8318 global list who is joining and JOINs it to the channel. This is
8319 for normal server, that is.
8321 Changed silc_server_send_notify_on_channel,
8322 silc_server_packet_relay_to_channel and
8323 silc_server_packet_send_to_channel check if we are normal server
8324 and client has router set (ie. global client) do not send the
8325 message to that client, as it is already routed to our router.
8327 * Implemented LEAVE notify type handling in silc_server_notify
8330 * Tested LEAVE command in router environment successfully. Tested
8331 with two routers, two servers and two clients.
8335 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8337 * Implemented SIGNOFF notify type handling in silc_server_notify
8340 * silc_server_remove_id now removes the client entry from all channels
8341 it has joined and thusly sends SIGNOFF notify type.
8343 * Rewrote the NAMES list generation in server by removing two excess
8344 loops. The lists are created now inside one loop.
8346 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8348 * silc_server_remove_channel_user checks now also global list
8349 for channel and client.
8351 * silc_server_new_channel_user checks now both local and global
8352 list for channel and client. Fixed a bug in client id decoding.
8353 Used to decode wrong buffer.
8355 * silc_server_channel_message checks now both local and global
8356 list for channel entry.
8358 * Tested channel joining (hence JOIN) in router environment
8359 successfully. Tested with two routers, two servers and two
8362 * Tested channel message sending in router environment successfully.
8364 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * Added silc_server_save_channel_key into server.[ch] to save the
8367 received channel key in Channel Key payload processing. It is
8368 also used in JOIN command reply handling.
8370 Equivalent function silc_client_save_channel_key added into
8371 client.[ch] into client library.
8373 * Changed JOIN command reply to send information whether the channel
8374 was created or not (is existing already) and the channel key
8375 payload. Changed protocol specs accordingly.
8377 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8378 the request was sent by ID and not by nickname. Crashed on
8381 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8383 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8384 now correctly save the received data.
8386 * silc_server_free_sock_user_data now notifies routers in the
8387 network about entities leaving the network.
8389 At the same time implemented functions silc_server_remove_id
8390 and silc_server_send_remove_id to receive and send REMOVE_ID
8391 packets. The packet is used to notify routers in the network
8392 about leaving entities. The ID removed will become invalid in
8395 * Added function silc_idlist_del_server into server. Removes and
8396 free's server entry from ID list.
8398 * silc_server_private_message function now checks, if we are router,
8399 that the destination ID really is valid ID, naturally.
8401 * In router when NEW_ID packet is received (for new client) the
8402 hash of the Client ID is saved in the ID Cache but the
8403 client->nickname is set to NULL, instead of putting the hash
8406 IDENTIFY command now also checks that client->nickname must be
8407 valid. If it is not if will request the data from the server who
8408 owns the client. Added new function
8409 silc_server_command_identify_check.
8411 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8412 to set the command to already allocated Command Payload.
8414 * Tested private message sending in router environment with two
8415 routers, two servers and two clients. Fixed minor bugs and now
8418 * Fixed segfault from client's NAMES command. Used to crash if
8421 * Forwarded packets must not be routed even if it is not destined
8422 to the receiver. Changed server code comply with this.
8424 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Added `require_reverse_mapping' boolean value to ServerParams
8427 structure. If TRUE (not default) the server will require that
8428 the connecting host has fully qualified domain name.
8430 If the reverse mapping is not required and hostname could not be
8431 found the IP address is used as hostname.
8433 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Implemented version string checking to both client and server.
8436 The check is incomplete currently due to the abnormal version
8437 strings used in development version of SILC.
8439 * Changed all command functions in server to use the new
8442 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Changed char *data to unsigned char *data in ID Cache system to
8445 support binary data as ID Cache data. Changed code to support
8446 binary data in lib/silccore/idcache.c.
8448 * Renamed silc_server_packet_relay_command_reply to
8449 silc_server_command_reply as it is normal packet receiving
8450 function. Rewrote the function to accept command replys for
8451 servers and not only for clients.
8453 * Mark remote router always as registered server if we are connecting
8454 to it. Otherwise, commands sent by the router to us are ignored.
8456 * All ID List find routines now returns the ID Cache Entry pointer
8457 as well if requested.
8459 * WHOIS command works now in router environment, tested with two
8460 routers, two servers and two clients.
8462 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8463 in router environment (as it is almost equivalent to WHOIS) but
8464 hasn't been tested thoroughly. Added new functions:
8466 silc_server_command_identify_parse
8467 silc_server_command_identify_send_reply
8468 silc_server_command_identify_from_client
8469 silc_server_command_identify_from_server
8471 * Disabled route cache adding because adding two different ID's with
8472 same IP replaces the old cache entry thus giving wrong route.
8473 The entry->router->connection is always the fastest route anyway
8474 so route cache may not be needed. Of course, new routes maybe
8475 established after receiving the ID when the entry->router->connection
8476 might not be anymore the most optimal.
8478 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8480 * Add route cache for received ID for fast routing.
8482 * Added silc_server_packet_route to route received packet on router
8483 that is not destined to us.
8485 * Renamed silc_server_get_route to silc_server_route_get.
8487 * Added id_string and id_string_len fields into SilcServer to
8488 include encoded ServerID for fast comparing without excess
8489 encoding of the ID's.
8491 * Cleaned up WHOIS command on server side. Added following static
8494 silc_server_command_whois_parse
8495 silc_server_command_whois_check
8496 silc_server_command_whois_send_reply
8497 silc_server_command_whois_from_client
8498 silc_server_command_whois_from_server
8500 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8501 arguments in command replies. All command functions should be
8502 updated to use this macro.
8504 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Minor typo fixes on command reply handling on server.
8508 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8510 * Added silc_server_command_add_to_channel internal routine to add
8511 the client to the channel after router has created the channel and
8512 sent command reply to the server.
8514 * Added generic silc_server_send_command to send any command from
8517 * Use static buffer with ID rendering instead of duplicating data.
8519 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8521 * Fixed a channel user mode bug when joining to a channel server gave
8522 everybody channel founder rights, oops.
8524 * We mark ourselves as the router of the incoming server connection
8525 if we are router ourselves. This way we can check in some packet
8526 sending functions whether it is locally connected server. For
8527 incoming router connections we put NULL.
8529 * For router sending packets locally means now always sending the
8530 packet cell wide; to local clients and local servers. For normal
8531 server sending packet locally means sending it to only local
8534 * Fixed the JOIN command to really work in router environment. If the
8535 channel is created it is always created by the router. Router is
8536 also responsible of making the initial joining to the channel,
8537 sending JOIN notify to the sending server and distributing
8538 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8539 does not exist server doesn't do anything else but forward the
8540 command to the router which performs everything.
8542 * Added silc_server_send_channel_key function to send the Channel Key
8545 * Added silc_server_create_channel_key to create new channel key. The
8546 channel key is now re-generated everytime someone joins or leaves
8547 a channel, as protocol dictates. Note: channel->key_len is the
8550 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8552 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8553 packet_receive.[ch] to separate packet sending and receiving
8554 routines. The server.[ch] now includes everything else including
8555 actual packet processing (writing and reading data) and other
8558 Renamed silc_server_private_message_send_internal to
8559 silc_server_send_private_message. The routine is still though
8560 used only to relay private messages as server does not send
8561 private messages itself.
8563 Renamed silc_server_new_channel to silc_server_create_new_channel
8564 and added new function sicl_server_new_channel that handles the
8565 incoming New Channel packet. Added also new sending function
8566 silc_server_send_new_channel to send New Channel Payload.
8568 * Added new function silc_server_notify to process incoming notify
8569 packet to the server/router. Server may then relay the notify
8570 to clients if needed.
8572 * Added new function silc_server_new_channel_user to process incoming
8573 New Channel User packet. Router will redistribute the packet and
8574 send JOIN notify to its local clients and locally connected servers
8575 if needed. Normal server will send JOIN notify to its local client
8576 on same channel when received this packet. Added also corresponding
8577 sending function silc_server_send_new_channel_user to sent the
8580 * Added boolean route argument to send_notif_to_channel and
8581 packet_send_to_channel functions to attempt to route the packet
8582 if it is TRUE and send only locally if it is FALSE.
8584 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8586 * silc_server_replace_id now broadcasts the received replace ID
8587 packet if it is not broadcast packet already. The router must
8588 broadcast to inform other routers about changed ID.
8590 * Added backpointer to server's router into SilcServer context in
8591 silcd/server_internal.h.
8593 * Fixed silc_server_packet_broadcast to send correct broadcast
8596 * The channel key is now distributed to the local client as soon
8597 as it is received from the router (in router environment) so that
8598 no other packet may be sent for the channel until client has
8601 * silc_server_remove_channel_user now broadcasts the received
8602 Remove Channel User packet if it is not broadcast packet already.
8603 The router must broadcast to inform other routers about removed
8606 * Added users field into SilcPacketContext that is a reference count
8607 of the context. One can increase the reference count by calling
8608 silc_packet_context_dup which is now changed to just increase the
8609 reference count instead of duplicating the data. The reference
8610 count is decresed by calling silc_packet_context_free that will
8611 free the data after the reference count hits zero.
8613 For now on the packet context and everything allocated into it
8614 (including the raw packet from network) must be freed by calling
8615 the new silc_packet_context_free function. Added also new function
8616 silc_packet_context_alloc that must be used now to allocate the
8617 context. This also means that if a routine is asynchronous from
8618 silc_[client/server]_packet_parse_type the packet context must
8619 be duplicated by calling silc_packet_context_dup. Otherwise it
8620 gets free'd after silc_[client/server]_packet_parse_type returns.
8621 Also, one must remember that if packet is duplicated then its
8622 reference count must be decresed by calling the free function as
8623 many times as it was duplicated.
8625 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8626 from both client and server.
8628 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8630 * Made joining to a channel working in router environment.
8632 * Cleaned up JOIN command on server side and create function
8633 silc_server_command_join_channel internal routine to make the
8636 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8638 * Changed silc_command_pending list to SilcDList. Also, added
8639 `ident' field to SilcServerCommandPending structure to identify
8640 the reply and to call correct callback.
8642 Added silc_server_command_pending_check function to replace the
8643 corresnponding macro. The silc_command_pending list is not
8646 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8647 to set identifier to previously allocated Command Payload. It
8648 is used to set identifier for command when resending Command
8651 * Added silc_command_payload_encode_payload to encode Command
8652 Payload buffer from SilcCommandPayload structure.
8654 * Added silc_argument_payload_encode_payload to encode Argument
8655 payload buffer from SilcArgumentPayload structure.
8657 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8659 * Changed WHOIS command to support router connection on server side.
8660 The whois request is always sent to router unless the server is
8661 standalone server. After server has received the reply from the
8662 router will it send the reply to the client.
8664 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8665 broadcast received broadcast packet. The function is used only
8666 by router. The broadcast packet is always sent to the router's
8669 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8670 render given ID to printable string, for log files for example.
8672 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8674 * Made basic router to router connections working. At least they
8675 can now connect to each other but nothing really works the way
8676 they are supposed - yet.
8678 * Added new initiator token to RouterConnection configuration
8679 file in silcd/serverconfig.[ch]. It is used to tell whether we
8680 are the initiator to the remote router or whether we'll expect
8681 the other end to connect.
8683 * Moved registering of listener task to silc_server_init, hence
8684 the server starts listenning as soon as it is run, even if it
8685 does not have connections to other routers. Let's see how well
8688 * Changed default connection retry timeouts for more suitable in
8691 * Removed cipher and such arguments from silc_idlist_add_client
8692 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8693 Added new function silc_idlist_add_data to add the keys and stuff
8696 * Added SilcIDListData structure and added it to SilcClientEntry
8697 and SilcServerEntry as their first field in the structure. This
8698 way we can explicitly cast the ID entries to the SilcIDListData
8699 structure and get common data for the entries. In past, we had
8700 to first check what type of connection it is and then cast it to
8701 correct ID entry type. Now, we can directly cast the opaque
8702 pointer to the SilcIDListData (no matter what ID entry it actually
8703 is) and get the data needed.
8705 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8707 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8708 in some circumstances even if threre were timeout tasks, though not
8709 IO tasks, but tasks anyway. Now fixed.
8711 * Defined SilcServerConnection structure to hold connection specific
8712 stuff about directly connected servers and routers. The definition
8713 is currently in silcd/server_internal.h. I thought about having
8714 a bit more important role fro this struct but for now it is used
8715 only when connecting to other server (or router actually).
8717 * Added connecting retry support in server when connecting to
8718 router(s). The retry feature implement exponential backoff
8719 algorithm. Also, added SilcServerParams structure to hold default
8720 parameters for server. For now, it include these retry settings
8721 and are hard coded. After server is moded to be as Silc Server
8722 Library this structure will be more important.
8724 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8726 * Changed client librarys channel->clients table to SilcList and
8727 changed code accordingly.
8729 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8731 * Changed client's channel table to SilcList and changed code
8732 accordingly. Also changed SilcChannelClientEntry to include back-
8733 pointer to the channel so that client entry can use that structure
8734 as list as well and we have fast cross-reference to the channel.
8735 This change dramatically decreased the complexity of channel
8736 handling with client entry and vice versa (removed one extra
8737 loop when searching for channel entry from many functions).
8739 * Changed server->sim from table to SilcDList and changed code
8742 * NAMES command can now be used from user interface. It will show
8743 the user list on the channel, neatly.
8745 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8746 Code now saves realname of the user if it becomes available.
8748 * Renamed configure.in to configure.in.pre and made ./prepare
8749 script to automatically add correct version string to
8750 configure.in which it creates from configure.in.pre.
8752 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8754 * NAMES command reply now shows users mode with the nickname when
8757 * Moved silc_client_ch[u]mode[_char] functions from
8758 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8759 place sucks, they are utility functions and should be in some
8762 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8764 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8767 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8771 * Added TRQ (efficient deque and list library) into lib/trq. This is
8772 a very good list library that is currently used in the SILC. Defined
8773 SilcList API over the library because I didn't like the API very
8774 much. See lib/trq/silclist.h for the API and examples of how to
8775 use the API. Fixed various places in the code to use the new
8776 SilcList API. The SilcList is meant for lists that has a structure
8777 already defined as a list. It is not suitable to add just some
8778 context to the list (in TRQ, the context is the list actually).
8780 So, I defined SilcDList that can be used for the purpose where
8781 predefined list structure does not exit. This can be used as
8782 such list. Now some context just can be added to the SilcDList.
8783 Currently this list is not used in the SILC just yet, though there
8784 are a lot places where this can replace dynamically allocated
8785 tables and I will fix these places, later, to use SilcDList.
8786 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8787 and use TRQ internally).
8789 Also fixed some annoying warning messages that the original TRQ
8790 code generated. Also minor changes to TRQ's Makefile.in.
8792 * Added support for querying by Client ID to both WHOIS and
8793 IDENTIFY commands into server, as required by the protocol.
8795 * Removed method function pointers from SilcBuffer structure. They
8796 weren't used to anything and just increased the context size for
8797 no good reason. This change also made silc_buffer_alloc and
8798 silc_buffer_free functions inline functions.
8800 * Disabled command flooding detection support until it's fixed so
8801 that it accepts commands in but does not execute them more than once
8804 * Added silc_net_localhost(), to return local hostname, into
8805 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8806 that must be initialized before calling silc_client_init.
8808 * Added new function: silc_server_send_notify_on_channels to send
8809 notify messages to all channels client has joined. It is assured
8810 that the message is sent only once per client.
8812 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8813 lib/silcutil/silcutil.[ch] as silc_format function. The new
8814 function is generic and is used by server as well, not only by
8815 the logging routines.
8817 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8818 the provided version string was not acceptable. Added new function:
8819 silc_ske_check_version into lib/silcske/silcske.h. The function
8820 must be implemented by the application (client or server) and it
8821 does not reside in the SKE library. The function checks the version
8822 string remote end sent.
8824 * Added back pointers (to opaque context and to SilcSocketConnection)
8825 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8827 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8828 duplicate packet context structure.
8830 * Changed `notify' client operation to send same arguments as client
8831 receives from server except for ID's. ID's are mapped to correct
8832 ID entry and that is returned. Also, if channel entry is not sent
8833 by server but the notify is for channel the channel entry is sent
8834 to application (otherwise application doesn't know that it is for
8835 channel (library gets it from packet's Destination ID)).
8837 * Added silc_client_remove_from_channels into client library to
8838 remove a client from all channels it has joined to. Used when
8839 received SIGNOFF notify from server. Added also new function
8840 silc_client_replace_from_channels to replace old ID entry with
8841 new ID entry on all channels. Used when received NICK_CHANGE
8844 * Fixed ID Cache list handling in silc_idlist_get_client in
8845 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8846 to get (or query) client by ID.
8848 * Updated TODO list.
8850 * Added connection authentication status message defined by the
8851 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8852 support for these into the code in client and server side.
8854 * Added generic function silc_client_send_command to send any command
8855 with variable argument list. Application should use this function
8856 to send commands if the command functions provided by the library
8857 does not suite for the application's user interface needs.
8859 * Added new `failure' client operation. Application is notified about
8860 received failure packet if client is executing a protocol. In this
8861 case the protocol's execution has failed.
8863 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8864 is required by the protocol.
8866 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8867 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8870 * Added status flag to SilcSKE object to indicate realtime status
8871 of the SKE protocol.
8873 * Application receives now exactly same command reply arguments as
8874 the library receives from server. However, if ID is received the
8875 corresponding ID entry is returned to the application (eg. Client
8876 ID is mapped to correct SilcClientEntry entry and that is returned).
8877 Changed command_reply client operation due to this change.
8879 * Changed all ID's in commands and in command replys as ID Payloads.
8880 Change affected both client and server side codes.
8882 All ID's sent in SILC network (with execption of ID's in SILC
8883 Packet header) are sent in ID Payload to support variable length
8886 * Server now notifies nick changes and notifies all clients on
8887 the channels about the new nickname (about the new Client ID,
8890 * Implemented CMODE command to change channel modes. Supports all
8891 channel modes defined by the protocol specs except ban and invite
8892 lists. (Also, private channel key mode is supported but support for
8893 setting private channel key in client is missing, thus, this mode
8894 has no effect on client side (except that server requires that the
8895 client uses private channel key and normal channel traffic does not
8898 Also, invite mode works per se, but INVITE command does not work
8899 yet correctly, so you can set channel as invite only channel but
8900 inviting clients to the channel does not work (it is yet to be
8901 thought what's the best way to do it).
8903 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8904 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8905 Implemented CUMODE command to change user's mode on the channel.
8906 Supports all modes defined by the protocol specs.
8908 * Added NAMES command reply to return users modes on the channel.
8910 * Removed unnecessary and slow ciphers from lib/silccrypt.
8912 * Set SO_KEEPALIVE option to connection sockets by default.
8914 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8916 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8917 redefined the Notify Payload into protocol specs.
8919 * Added silc_id_payload_parse_id to get ID directly from raw
8922 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8924 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8925 accept searching by Client ID as well.
8927 * Added support for LEAVE and SIGNOFF notify types in client library.
8929 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8930 to parse ID Payload from raw data.
8932 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8934 * Added flags parameter into silc_ske_assemble_security_properties
8935 function in lib/silcske/silcske.[ch].
8937 * Changed notify client operation to fit better for notify messages
8938 sent by server. The notify payload received from server is now
8939 passed to the application (after parsing it to SilcNotifyPayload).
8940 It is application's responsibility to retrieve the arguments
8941 from the payload and show the message the way it wants. The message
8942 sent by server is implementation specific.
8944 * Changed public keys to comply with the protocol specification.
8945 Old public keys are not supported anymore and are not compatible.
8947 * Removed nickname from Channel Payload as the latest draft removed
8948 it. The client must resolve the nickname from the NAMES command
8949 reply received when it joined the channel.
8951 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8953 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8955 * Fixed some errors in protocol specification drafts.
8957 * Created lib/silccore/silcnotify.c to implement Notify Payload
8958 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8959 generic payloads described by protocol specifications. The file
8960 includes implementations for ID Payload and Argument Payload.
8962 * Changed Command Payload implementation to use the new Argument
8963 Payload. Changed command_xxxx_payload to command_payload_xxxx
8964 to comply with SILC coding conventions.
8966 * Added suppport for Argument Payload handling in Notify Payload
8967 implementation as protocol requires it. Added the new support
8968 into server and client lib as well.
8970 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8972 * Added support for multiple nicknames on same channel. [n] is
8973 added locally to the nickname if there are more than one same
8974 nicknames on the channel.
8976 * Server now sends all nicknames that matched WHOIS request.
8977 Client also shows the list received from server.
8979 * Added TOPIC command to client side. User can now set and show
8980 current topic on channel.
8982 * Added MOTD command to client and server. Also, server sends the
8983 motd when client connects to the server.
8985 * Changed version strings to comply ISO 8601.
8987 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8989 * Fixed protocol error handling in client library. It should now
8990 cope even if the SKE fails for some reason.
8992 * Made new protocol specification drafts for submitting to IETF.
8994 * Implemented TOPIC command to server in silcd/command.c.
8996 * Added two new notify types into lib/silccore/silcnotify.h:
8997 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8998 notify nickname change and topic setting/change on a channel.
9000 * API change of command_reply operation in client library. The
9001 application gets now the status type received from server as well.
9003 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9005 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9007 * Cras fixed and optimized the packet handling even further and
9008 it should work now. Minor change to the prototype of function
9009 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9011 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9013 * Added new function into lib/silcutil/silcschedule.[ch]:
9014 silc_schedule_with_fd to select() a specified fd. The function
9015 returns after timeout expires or data arrives or goes. The
9016 function is used by packet routines to wait that all data is
9017 received from network.
9019 * Fixed data reading from network in lib/silccore/silcpacket.c.
9020 The code now assures that all data is read from the fd and then
9021 continues packet processing. This was a bug fix since the code
9022 used to drop some data in some circumstances.
9024 * Added new function into lib/silcclient/client.[ch]:
9025 silc_client_start_key_exchange to start key exchange after
9026 connection has been established to server. The code internally
9027 now uses this funtion but its main purpose was to provide it
9028 for applications that perform their own connecting. After
9029 application has created a connection it merely calls this
9030 function to start the key exchange between client and server.
9031 The library takes care of everything else after that.
9033 Updated also lib/silcclient/README to explain the usage of
9036 * Do not send to application information that connection has
9037 been established. Application gets notified it by connect
9040 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9042 * Applied cras's patch to add silc_schedule_one function. The
9043 function runs scheduler once and returns.
9045 * Fixed the scheduler after cras messed it up. The timeout
9046 handling works now as it's supposed to work.
9048 * Added into lib/silccore/ silcnotify.h to include notify
9049 message types support. Changed silc_server_send_notify*
9050 functions, in server.[ch], to support those new notify types.
9051 Added the support for the notify types into client library,
9052 as well. Added new notify client operation into ops.h in
9055 * Changed silc_server_packet_send_to_channel to send normal
9056 packets instead of just channel message packets. The function
9057 is now used to send the notify packets to channels. It is not
9058 used to send channel message packets anymore, as server never
9061 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9062 va_arg()s as it seems to require it nowadays. I guess, if SILC
9063 is compiled with older va_arg() the new code should work anyway.
9065 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9067 * Splitted core library. Core library (lib/silccore) includes
9068 now only SILC protocol specific core (and common) components.
9069 Created new utility library (lib/silcutil) that includes more
9070 generic purpose stuff. The stuff for util library was taken
9071 from the old core library. This was minor and easy split.
9073 * Created SILC Client Library (lib/silcclient) that includes
9074 implementation of the SILC client without user interface. This
9075 was major move from silc/ directory. The code has been changed
9076 so that it is transparent towards the user interface. The
9077 silc/ directory includes now the same user interface as before
9078 and it uses the new client library. Read lib/silcclient/README.
9079 Basicly, the client library performs everything else related
9080 to SILC except user interface handling. Also, configuration
9081 files are considered to be part of user interface and library
9082 does not handle them.
9084 This change also changed a lot of structures, function naming etc.
9085 Most important change was that SilcClientWindow object was
9086 renamed to SilcClientConnection in the client library. Created
9087 also new file lib/silcclient/ops.h. Also added new files
9088 silc/local_command.[ch] and silc/client_ops.[ch].
9090 All these changes were made to make it easier for user interface
9091 designers to create what ever user interface for the SILC client
9094 It is also expected that the server will be moved to lib
9095 directory as well and SILC Server Library will be created;
9096 sometimes in the future.
9098 * Removed Local commands from lib/silccore/silccommand.h as
9099 they are application specific and new client library does not
9100 handle any of those anymore.
9102 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9103 old client implementation in silc/.
9105 * Added support for callback functions in SILC_LOG_* macros.
9106 Application can now set its own callbacks that will be called
9107 instead of using the default functions that will always print
9108 the debug messages to stderr (or stdout). Also, debugging can
9109 now be disabled by setting silc_debug to FALSE and re-enabled by
9110 setting it to TRUE. Note, that logging will still work even
9111 if debugging is disabled.
9113 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9114 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9115 silc_log_reset_debug_callbacks.
9117 * To enable debugging in silc client one must give now -d
9118 option on command line.
9120 * Changed silc_schedule_init to automatically allocate task queues
9121 if they are not allocated before calling it.
9123 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9125 * Added GMP 3.1 into math library.
9127 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9129 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9130 a channel in SILC network. The packet is used by servers and
9131 routers to notify other routers that user has left a channel.
9132 This little feature was missing until now. Added the feature
9133 to protocol specification as well.
9135 Added functions: silc_server_send_remove_channel_user and
9136 silc_server_remove_channel_user into server.[ch].
9138 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9139 lib/silccore/silcpacket.h. However, they are not implemented
9142 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9144 * Fixed joining to a channel and sending channel messages
9145 between server and router. The channel message sending should
9146 now work inside a cell.
9148 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9150 * Fixed the private message sending between server and router.
9151 The private message sending should now work inside a cell.
9153 * Added silc_server_replace_id into server.[ch] to replace
9154 existing ID in the SILC network.
9156 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9157 and silc_idlist_replace_server_id into idlist.[ch] in server.
9159 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9161 * Fixed the server to server connections. Server can again now
9162 connect to router. Router to router connections probably does
9165 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9167 * Added dynamic protocol registering support. Now protocols can
9168 registered and unregistered on the fly. Patch by cras.
9170 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9172 * Added lib/contrib directory to hold routines that some platforms
9173 don't have but are needed by SILC.
9175 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9176 into lin/contrib to provide getopt() and getopt_long() for
9177 those who don't have it.
9179 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9181 * Added AWAY command to client. When away message is set and
9182 client receives a private message packet the client automatically
9183 replies to the sender with the away message.
9185 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9186 bug seemed to be the cause of recent problems when compiling
9189 * Added version detection support to SKE protocol specification
9190 and added the new changes to the SKE implementation as well.
9191 There were other minor changes in the SKE protocol as well.
9193 Many changes in lib/silcske/silcske.[ch] and in
9194 lib/silcske/payload.[ch].
9196 * Added ^U functionality, clear input line. Patch from cras.
9198 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9200 * Mainly small bugfixes on core library. Fixed some debugging
9201 logging and buffer overflow in silclog.c.
9203 * Updated config.sub and config.guess on the distribution tree.
9205 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9207 * Added command lagging support in server. Client may execute
9208 commands now only once in two seconds.
9210 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9212 * Optimized packet reception. MAC computation and checking is now
9213 also more optimized. A lot previously duplicated code is now
9214 used as generic by both client and server.
9216 * Fixed key pair generation in clientutil.c
9218 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9220 * Added into lib/silccore/silcbufutil.[ch] new function;
9221 silc_buffer_realloc.
9223 * Moved generic packet sending/encryption functions to
9224 lib/silccore/silcpacket.[ch] from client and server. Some
9225 rewriting of the functions.
9227 * Moved all generic packet reception/decryption functions to
9228 lib/silccore/silcpacket.[ch] from client and server. The
9229 packet processing is now much cleaner in both client and server.
9230 These were major changes in both client and server.
9232 * Created many common functions in server to do packet sending.
9233 Previously code were duplicated a lot, this has been removed
9236 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9238 * Rewrote major parts of the ID cache system. Don't know
9239 whether it is better now or not but at least the API is more
9242 * Major rewrite on ID cache stuff on client because of the ID
9243 cache API changes. Added idlist.c to client.
9245 * Also major rewrite on ID cache stuff on server as well.
9246 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9247 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9248 in hand, instead they are all put into the ID cache system now.
9249 All server_idlist_* routines uses ID cache now instead of
9250 traversing its own lists (those lists does not exist anymore).
9251 SilcIDList though still exists. Also, SilcXXXEntry's are
9254 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9256 * Finally made the SKE implementation compliant to the protocol
9257 specification. All mp integers are now binary encoded as
9258 opposed being HEX encoded.
9260 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9263 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9264 functions: silc_[encode/decode]_pem. Also added function
9265 silc_encode_pem_file to PEM encode with newlines ('\n') for
9268 * SILC public keys are now encoded either PEM or binary. Same
9269 option is for private keys as well. By default private keys
9270 are binary encoded and public keys PEM encoded. Silly HEX
9271 encoding were removed.
9273 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9274 function to create fingerprints.
9276 * Fixed a bug in SHA1; does not change the original data anymore.
9278 * Partly implemented INFO command on client and server side.
9279 Fixed CLEAR command. Changes to SERVER command; show current
9280 server(s) when giving command without arguments. Added
9281 VERSION command to client.
9283 * Added check to server that unregistered connections cannot
9284 execute commands (unless it is specificly allowed).
9286 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9288 * Fixed screen refresh.
9290 * Fixed channel joining bug from client. On some circumstances
9291 client tried to join to a channel it had already joined.
9293 * Added public key verification process into client's protocol.c.
9294 The client now verifies the public key from user and saves
9295 it into ~./silc/serverkeys/ directory.
9297 Added into: clientutil.[ch]: silc_client_verify_server_key.
9299 * Changed SKE protocol's silc_ske_initiator_finish function
9300 to accept callback function that verifies the received public
9301 key. Removed old silc_ske_verify_public_key function.
9303 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9305 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9306 silc_pkcs_private_key[_data]_set.
9308 * Made the password and public authentication more cleaner in
9309 server's protocol.c.
9311 * Removed historic and obsolete protocol `channel_auth' from
9312 both client and server.
9314 * Removed wrong way of sending command status messages from
9315 server to client in server's command.c. The old way violated
9316 protocol specification.
9318 Changes to silccore/silccommand.[ch]: removed
9319 silc_command_encode_status_payload -> not needed anymore,
9320 changed silc_command_encode_payload_va to accept extra
9321 argument on variable argument list. The argument type must
9322 now be provided to the function. Also, added new function:
9323 silc_command_encode_reply_payload_va which is same as
9324 normal command_encode_payload_va except command status type
9325 is provided as extra argument.
9327 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9329 * Added ~./silc directory handling. The directory includes the
9330 public and private keys for the client.
9332 Added silc_client_check_silc_dir, silc_client_create_identifier
9333 and silc_client_load_keys.
9335 * Implemented SILC protocol compliant public key. Added public
9336 and private key saving to and loading from files.
9338 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9339 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9340 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9341 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9342 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9344 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9345 silc_pkcs_load_[public/private]_key.
9347 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9349 * Added silc_server_get_route (route.[ch]) to get connection
9350 data for the fastest route for given ID.
9352 * Implemented INVITE command on client and server. The command
9353 were re-defined in the SILC Protocol Specification and the
9354 implementation now complies with the specification.
9356 * Implemented PING command on client and server.
9358 * Implemented NAMES command on client and server. The server side
9359 supports currently only normal server not router server yet.
9360 Some changes to NAMES definition in SILC protocol specification.
9362 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9364 * Implemented LEAVE command on client and server.
9366 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9367 again. This change was made to the protocol as well. Server
9368 should not violate the protocol specification anymore.
9370 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9372 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9373 was tested. SOCKS4 was not but should work anyway.
