9 SilcVCard context. The silc_vcard_free now checks whether
10 the context is dynamically allocated or not. Affected files
11 are lib/silcutil/silcvcard.[ch].
13 Mon Oct 14 17:55:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Periodically remove the NOATTR status from client entry
16 so that the client may take the attributes in use even after
17 server has resolved them unsuccessfully earlier. Affected
18 file silcd/server_query.c and idlist.h.

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

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

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

599 * Added silc_client_udpate_server function to update changed
600 server info. Affected file lib/silcclient/idlist.[ch].
602 * Added check for server entries that are being resolved when
603 notify is received. If being resolved, handle the received
604 notify only after it's resolved so that all notifys are
605 handled in same order as received from the server.
607 Added similar resolver check to channel entries. Every
608 notify that cause resolving of any information that affects
609 channel entry marks the channel entry in waiting state.
610 After whatever resolving is over the waiters are signalled
611 and only then the notifys are handled in the same order
612 as delivered from the server.
614 Affected files are lib/silcclient/idlist.[ch], and
617 * Fixed KILLED notify handling in normal server. Affected
618 file silcd/packet_receive.c.
620 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
621 is locally connected, or was locally connected (but may
622 be detached and connection is not active). Added also
623 SILC_IS_LOCAL for checking this status. Affected files
624 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
625 silcd/server.c and silcd/server_internal.h.
627 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
629 * Don't send or handle TOPIC_SET if topic is already set and
630 is same as being set. Affected files silcd/command.c and
631 silcd/packet_receive.c.
633 * Fixed CMODE change rights checking to work correctly when
634 removing modes by operator. Affected file is
637 * Fixed some handling with New Channel packet in router and
638 fixed some CMODE_CHANGE notify handling in server and router.
639 Affected file is silcd/packet_receive.c.

646 Affected files configure.in.pre, lib/contrib/Makefile.am.
648 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
650 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
651 to the sender of the notify too, to avoid situation where two
652 notifys are in the network at the same time going to oppsite
653 directions. Affected file silcd/packet_receice.c.
655 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
657 * Delete the client from channel even if the cilent->id is
658 NULL. It was possible that client was deleted without
659 removing from channels (theoretically at least). Affected
660 file silcd/server.c and silcd/server_util.c.
662 * Free the client data too when resuming is not successful.
663 Affected file silcd/packet_receive.c.
665 * Merged some code from c0ffee's silc-plugin. Affected files
666 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
668 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
669 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
670 to the primary router connection, the other one returns
671 TRUE if packet must be broadcasted to network.
673 * All notifys that are destined to primary router (to network)
674 are now automatically sent to backup routers even if the
675 router is standalone (and has backup router). Affected files
678 * Added --without-irssi and --without-silcd configuration
679 options for disabling the compilation of these applications.
680 Affected file configure.in.pre and prepare.

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

746 that the one authenticating becomes the only founder on the
747 channel. Affected file silcd/command.c.
749 * Better checking for founder mode setting when CUMODE_CHANGE
750 notify is received. Affected file silcd/packet_receive.c.
752 * Close all connections when shutting down the server by sending
753 DISCONNECT packet. Close all listeners too when shutting
754 down the server. Affected file silcd/server.c.

829 The one that authenticated will become founder and anyone
830 else is demoted. Affected file silcd/command.c.
832 * Added error printing of any error that has occurred during
833 any command in client library. Affected file is
834 irssi/src/silc/core/client_ops.c.

1256 * Added resolve_cmd_ident field to the SilcClientEntry structure
1257 too so that if the entry is for example being resolved so
1258 another command may attach to the same pending command reply
1259 without requiring to resolve the same entry again. Added
1260 support for adding multiple pending commands for one
1261 command idenfier. Affected files lib/silcclient/command.[ch],
1262 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
1264 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1275 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
1276 and lib/silcclient/command_reply.c.
1278 * Save the channels list in WHOIS command reply in normal server
1279 so that WHOIS always shows joined channels also in normal
1280 server and not just on router. Affected file is
1281 silcd/command_reply.c.
1283 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1341 * Redefined the Status Payload to include now two 8 bit fields,
1342 instead of one 16 bit field. This now makes it possible to
1343 send list of errors. Updated the protocol specs and the code
1344 in core library, client library and server. Protocol TODO #1.
1345 Affected files are lib/silccore/silccommand.[ch],
1346 lib/silcclient/command_reply.[ch], silcd/command.c,
1347 silcd/command_reply.c and silcd/packet_receive.[ch].
1349 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1351 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1352 must be handled by the application and should tell the application
1353 that an error message was already printed, and it should print the
1354 config coords (line, filename, ...). Affected files are
1355 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1357 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the

1376 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1378 * Added STATS command to the protocol after all, to return
1379 various statistical information about the network. It can
1380 be used by clients to retrieve statistical information, and
1381 servers may use it to to fetch cell and network wide
1382 statistics from router. Updated the protocol specs and
1383 implemented it to the server. Protocol TODO #16.
1384 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1389 * The LIST command reply in client libary now adds new channel
1390 entry if the returned channel doesn't exist yet in cache,
1391 and returns the channel entry to the application in the
1392 command_reply client operation. Affected file is
1393 lib/silcclient/command_reply.c.
1395 * Changed the channel message payload's MAC generation to
1396 include the IV in the MAC as well. This way all relevant
1397 parts of the channel message payload are authenticated also
1398 with the channel message MAC (and not only by packet MAC).
1399 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1400 Affected file is lib/silccore/silcchannel.c.
1402 * Fixed the SKE to save the remote version, since the
1403 silc_ske_parse_version mistakenly checked wrong version,
1404 after it replaced the start payload. Affected files are
1405 lib/silcske/silcske.[ch].
1407 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1447 it to protocol specs and implemented it to client and server.
1448 Protocol TODO #13. Affected files are silcd/command.c,
1449 silcd/packet_receive.c, packet_send.[ch],
1450 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1451 The killer's client entry is now returned to application in
1452 the `notify' client operation.
1454 * Fixed the Max Argument fields that had too large value set
1455 in the protocol specs. Protocol TODO #14.
1457 * Added the LEAVE command reply to return the ID of parted
1458 channel. Updated protocol specs and implemented it to the
1459 client and server. Protocol TODO #15. Affected files are

1471 file is silcd/command.c.
1473 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1474 generic reply to a generic request (REQUEST flag), and
1475 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1476 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1477 to define the payload for DATA flag. Added the flags to
1478 the implementation. Protocol TODO #9. Affected file is
1479 lib/silccore/silcchannel.h.
1481 Changed the client library to return the message length
1482 to application as well in the channel_message and private_message
1483 client operations. Affected files are

1523 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Some client implementations quit network by doing first LEAVE
1526 and then immediately SIGNOFF (like Bombyx). We now do check
1527 after a short time after LEAVE notify and check whether the
1528 client is still valid after LEAVE, and if not we remove it from
1529 cache. Affected file is lib/silcclient/client_notify.c.
1531 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1556 to const. Affected files are lib/silccrypt/silccipher.[ch],
1557 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1559 * Changed the silc_get_username and silc_get_real_name to
1560 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1562 * Fixed the Irssi SILC Client to use the silc_get_username and
1563 silc_get_real_name insted of glib routines since the glib
1564 routines only corrupt stack. Fixes the Irssi SILC to work in
1565 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1567 * Fixed the Irssi to not use g_get_home_dir since it crashes
1568 or returns garbage on cygwin and corrupts stack. Added function
1569 get_home_dir to Irssi routines. Affected files are
1570 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1572 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1575 entry structure. Optimized SilcTask structure. Optimized
1576 SilcPacketContext structure.
1578 Affected files lib/silcsftp/sftp_fs_memory.c,
1579 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1581 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1583 * And yet again reverted back the config thing since Johnny
1584 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1587 * Fixed memory leaks from config object. Affected files are
1588 silcd/serverconfig.[ch].
1590 * Added support for adding new connections to the server in rehash.
1591 After rehash they take effect.
1593 Added support for changing the maximum allowed connections in
1594 rehash. The number can grow but going smaller is not supported.
1596 Added function silc_server_num_sockets_by_remote to the
1597 silcd/server_util.[ch].
1599 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1601 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1603 * Added preliminary checking during config parsing for a valid
1604 public/private key and removed further checks in the code.
1605 Affected files are silcd/serverconfig.[ch], server.c.
1607 * Moved functions silc_server_drop() and silc_server_daemonise()
1608 from server.c to silcd.c since they are stricly related to
1609 the application activity.
1611 * Reverted a small part of the automatic ref/unref since
1612 it caused a double unref in some situations. Affected
1613 files are silcd/silcd.[ch], server.c, serverconfig.c.
1615 * Added some .cvsignore files in the lib directory.
1617 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1619 * Fixed silc_net_gethostbyaddr to correctly resolve by
1620 address. Affected file lib/silcutil/silcnet.c.
1622 * Fixed the notify relaying to client. The HMAC to be used
1623 with relayed packets ws wrong and caused decryption failure
1624 at the client end. Affected file is silcd/packet_receive.c.
1626 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Created new branch silc_protocol_1_0_branch.
1630 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1632 * Changed the silc_server_config_* routines to be SilcServer
1633 independent. They are now officially application specific code
1634 and not part of generic server implementation. Affected files
1635 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1637 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1639 * Added automatic referencing of config context in the
1640 silc_server_config_alloc, and automatic unreferencing in the
1641 silc_server_config_destroy. Affected files are
1642 silcd/serverconfig.[ch], silcd/silcd.c.
1644 * Fixed the silc_log_quick handling in the logging routines.
1645 It didn't log quickly when it was TRUE. Affected file is
1646 lib/silcutil/silclog.c. Also the flush delay was set even
1647 if it was 0 in config file. Affected file is
1648 silcd/serverconfig.c.
1650 * Added support for changing key pair of the server in rehash.
1651 Affected file silcd/server.c.
1653 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1655 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1656 too early, before getting the channel entry. Affected file
1657 is silcd/packet_receive.c.
1659 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1661 * Added functions silc_server_config_[ref/unref], these are used
1662 to prevent that the config object is destroyed.
1664 No longer directly affect global variables silc_log_quick and
1665 silc_log_delay, they are first cached inside the config object
1666 and then applied with silc_server_config_setlogfiles().
1668 silc_server_config_set_defaults() is now internal to
1669 serverconfig.c, there are no reasons to show this internal stuff
1672 Affected files are silcd/serverconfig.[ch].
1674 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1675 fprintf's to stderr, since some code may be executed again after
1676 the server went into the background. Affected files are
1679 * Added rehash support. Added function silc_server_rehash() that
1680 will perform all the basic tasks of the rehashing procedure.
1682 * Added command line option `-x, --hexdump'. This will enable the
1683 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1684 The option `--hexdump' implies `--debug'.
1686 * Fixed a bad bug in the logging APIs (silcutil library) where
1687 the application would crash after calling silc_log_reset_all().
1689 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1691 * Fixed the KICKED notify handling in client library to
1692 correctly remove the channel and all entries from the
1693 channel when I was kicked. This bug crashed the client.
1695 Fixed yet another but in KICKED notify handling to remove
1696 the kicked client correctly from the channel.
1698 Affected file is lib/silcclient/client_notify.c.
1700 * Fixed a minor bug in looking up correct client entry
1701 in KICKED notify in server. Affected file is
1702 silcd/packet_receive.c.
1704 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1705 sources correctly to distribution. Fixes --with-gmp option.
1707 * Removed the manual rehashing from ID Cache, and changed it
1708 to use the SILC Hash Table's auto rehash feature. Affected
1709 file is lib/silccore/silcidcache.c.
1711 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed a bug in the silc_client_nickname_format function that
1714 handles the multiple same nickname formatting. Two clients
1715 with same nickname caused problems after the first one left
1716 and rejoined. It didn't format the nickname correctly.
1717 Affected file is lib/silcclient/idlist.c.
1719 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Don't change the topic if olod topic is same as new one.
1722 Affected file is silcd/packet_receive.c.
1724 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1726 * Added cross-reference support to the SILC Documentation
1727 generator. All types across all HTML files are now cross-
1728 referenced. Affected files util/robodoc/generator.c and
1729 scripts/silcdoc/silcdoc.
1731 * Added file lib/silcutil/silctypes.h to include all the
1732 arithmetic type definitions and some macros. Removed
1733 includes/bitmove.h and moved macros to silctypes.h.
1735 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1739 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1741 * Added `type' argument to silc_id_payload_parse_id function which
1742 now returns the type of the ID to the sent pointer. Affected
1743 file is lib/silccore/silcid.[ch].
1745 * Added check for CMODE_CHANGE notify type that mode change is
1746 allowed by the sender. Affected file silcd/packet_receive.c.
1748 * Added check for CUMODE_CHANGE notify type that mode change is
1749 allowed by the sender. Affected file silcd/packet_receive.c.
1750 Added the ID type as CUMODE_CHANGE notify type as argument
1751 to the `notify' client operation. Affected files are
1752 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1754 * Added function silc_client_add_server to the client library.
1755 Added support for resolving also channel and server info when
1756 received unknown entity in notify packet. Affected files are
1757 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1759 * Added function silc_command_get_status to return the command
1760 status from the command reply's argument payload. Affected files
1761 are lib/silccore/silccommand.[ch].
1763 * Added check for KICKED notify type that the kicking is
1764 allowed by the client. Affected file silcd/packet_receive.c.
1766 * Created function silc_get_input which can be used to get input
1767 (echo on or off) from user on command line. Affected files are
1768 lib/silcutil/silcutil.[ch].
1770 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * Optimized silc_server_packet_relay_to_channel function.
1773 Added new function silc_channel_message_payload_encrypt which
1774 can be called directly if channel message payload needs to
1775 be encrypted and is already encoded (no need to call _encode
1776 function). Packet relaying is now done by router without any
1777 extra memory allocations. Affected files are
1778 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1779 silcd/packet_send.c.
1781 * Fixed the INVITE notify handling. It took wrong arguments
1782 as invite list and invite delete. Affected file is
1783 silcd/packet_receive.c.
1785 * Added check for TOPIC_SET notify type that the topic change is
1786 allowed by the client. Affected file silcd/packet_receive.c.
1788 * Added check for INVITE notify type that inviting is allowed by
1789 the client. Affected file silcd/packet_receive.c.
1791 * Changed the silc_server_client_on_channel to return the
1792 SilcChannelClientEntry as well. Moved the function
1793 silc_server_check_cmode_rights to server_util.[ch].
1794 Affected files are silcd/server_util.[ch], silcd/command.c.
1796 * Added function silc_server_check_umode_rights to check whether
1797 changing client's user mode is allowed. Added check for
1798 UMODE_CHANGE notify type that the umode change is allowed
1799 by the client. Affected files are silcd/server_util.[ch],
1800 silcd/packet_receive.c and silcd/command.c.
1802 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1804 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1805 ID length. It ignored that ID can be IPv6 based as well.
1806 Affected file lib/silccore/silcpacket.h.
1808 * Fixed the silc_id_id2str and silc_id_str2id to take the
1809 IPv6 address offset's into consideration. Affecte file is
1810 lib/silccore/silcid.c.
1812 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed the internal Unix scheduler functions to check for
1815 NULL context they may receive. The affected file is
1816 lib/silcutil/unix/silcunixschedule.c.
1818 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1820 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1821 can specify different directory with --home command line
1822 parameter. Affected files irssi/src/silc/core/client_ops.c,
1825 * SILC-specific commands aren't now executed if the active server
1826 isn't of SILC-type, so there won't be problems with having
1827 IRC and SILC protocol support in same client. Affected files
1828 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1831 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1833 * Improved the signal support in SILC Schedule. Added new
1834 function silc_schedule_signal_call which is used by application
1835 to mark a signal to be called. It is now safe to perform
1836 any kind of tasks in signal callbacks since it is guaranteed
1837 that the application specified signal callback is called
1838 after the signal is over. Affected files are
1839 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1841 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1843 * Added `name' field to SilcChannelPrivateKey to represent
1844 application given name for the key. Moved also the context from
1845 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1846 Added the `name' argument also to the function
1847 silc_client_add_channel_private_key.
1849 Added function silc_client_current_channel_private_key to set the
1850 current channel private key in use.
1852 Added "change" command to KEY command which can be used to change
1853 the current channel private key. Bound the command also to
1854 alt+K (Alt+Shift+k).
1856 Also affected files lib/silcclient/client_channel.c,
1857 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1859 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1861 * Added silc_rng_get_byte_fast function in to the
1862 lib/silccrypt/silcrng.[ch].
1864 * Changed the interface of silc_packet_assemble and the
1865 silc_packet_send_prepare. If silc_packet_assmble is now
1866 called the application does not call silc_packet_send_prepare
1867 because the library will call it automatically. These
1868 interfaces now also return a reference to the outgoing buffer
1869 which includes the assembled packet, which the application can
1870 use to encrypt the packet.
1872 Affected files are lib/silccore/silcpacket.[ch],
1873 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1874 silcd/packet_send.c, server_backup.c and packet_receive.c.
1876 * Fixed a packet sending bug on very high load, where outgoing
1877 packet queue wasn't handled correctly and packets got corrupted.
1878 Affected files are lib/silcutil/*/silc*sockconn.c,
1879 lib/silcclient/client.c and silcd/server.c.
1881 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1883 * Added macro SILC_PACKET_DATALEN which can be used during
1884 packet assembling to check whether the data to be added to
1885 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1886 len is truncated until it fits it.
1888 Added checks for maximum length of channel message payload and
1889 private message payload also.
1891 Added checks for maximum packet length in server and in
1894 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1895 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1896 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1897 lib/silcclient/client_prvmsg.c.
1899 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1901 * Added silc_server_packet_queue_purge call to the
1902 silc_server_disconnect_remote to assure that all data in the
1903 queue before disconnecting is sent to the network. Affected
1904 file silcd/server.c.
1906 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1908 * Added the deleting of server's own ID cache entry to the
1909 silc_server_free function. Free also everything else that
1910 has been allocated in silc_server_init. The affected file
1913 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1915 * Added functions silc_parse_version_string, silc_version_to_num,
1916 and silc_ske_parse_version to parse SILC protocol style version
1917 strings. Affected files lib/silcutil/silcutil.[ch] and
1918 lib/silcske/silcske.[ch].
1920 * Added new configuration params: version_protocol, version_software
1921 and version_software_vendor to specify what version the remote
1922 host must at least be to be able to connect to server. The vendor
1923 string can be regex matched too. Added new function
1924 silc_server_connection_allowed to check maximum number of allowed
1925 connections, and allowed versions for incoming connections.
1926 Affected files are silcd/server.c, server_util.[ch] and
1929 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1931 * Added preliminary support for signals in scheduler. The
1932 signals we care about are now blocked always when the scheduler
1933 is locked. This way we can synchronise the use of signal with
1934 scheduler. It is guaranteed that when signal occurs the scheduler
1935 is not locked, and thus new tasks can be safely added to the
1938 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1939 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1940 Added new platform specific routines
1941 silc_schedule_internal_signals_[un]block and
1942 silc_schedule_internal_signal_[un]register.
1944 Added new functions to SILC Schedule API:
1945 silc_schedule_signal_[un]register. Each signal that application
1946 is going to use should be registered to the scheduler.
1948 Affected files are lib/silcutil/silcschedule.[ch],
1949 lib/silcutil/*/silc*schedule.c.
1951 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1953 * Check for unauthenticated client and server in the
1954 silc_server_new_client and silc_server_new_server functions.
1955 Affected file silcd/packet_receive.c.
1957 * Added function silc_string_is_ascii to check whether given
1958 string is 7-bit ASCII string. Affected files are
1959 lib/silcutil/silcutil.[ch].
1961 * Added function silc_id_is_valid_server_id into the
1962 silcd/serverid.c and added checking for valid Server ID's in
1963 silc_server_new_server. The Server ID must always be based
1964 on the server's public IP address.
1966 * Added logging of DISCONNECT packet message in the server.
1967 Affected file silcd/server.c.
1969 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1971 * Changed all library interfaces that use Global RNG to also
1972 accept SilcRng as argument. Affected files are
1973 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1974 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1975 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1976 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1977 lib/silccrypt/rsa.c.
1979 * Added function silc_pkcs_generate_key to the
1980 lib/silccrypt/silcpkcs.[ch] for applications so that they
1981 don't need to do pkcs->pkcs->init calls anymore.
1983 * Remove SilcSocketConnection from the SFTP API since it really
1984 wasn't needed there. The application has the information
1985 saved in its contexts anyway and the SFTP layer doesn't need
1986 know about it. Affected files lib/silcsft/silcsftp.h and
1987 lib/silcsftp/sftp_[server/client].c.
1989 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1990 The SilcSimContext is not SilcSim.
1992 * Fixed possible buffer overflows in silc_id_render in the
1993 lib/silcutil/silcutil.c.
1995 * On EPOC the global crypto module lists are not used at all
1996 in the crypto library. Added support for using the constant
1997 algorithm list on EPOC. Affected files are
1998 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2001 * Fixed the handling of third parameter of KICKED notify, since
2002 it was mistakenly updated to SILC Protocol 1.0 even though it
2003 is to be included in 1.1. Since it is not in 1.0 it is not
2004 mandatory, and this fix now handles it only if it is provided,
2005 and it is not error if it is not provided. Affected file
2006 lib/silcclient/client_notify.c.
2008 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2010 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2011 client. Affected file irssi/src/silc/core/client_ops.c.
2013 * Merged with Irssi 0.8.4 from irssi.org CVS.
2015 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2017 * Check for valid socket connection in client entries before
2018 sending any messages. Fixes a crash, but doesn't fix some
2019 other underlaying bug that is lurking there. Affected
2020 file silcd/packet_send.c.
2022 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2024 * $usermode, $cumode and $cumode_space expandos shouldn't do
2025 anything with non-SILC server records. Affected file
2026 irssi/src/silc/core/silc-expandos.c
2028 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2030 * Fixed the silc_net_check_[host/local]_by_sock to support
2031 IPv6 bound sockets as well. Now they can return IPv6 addresses
2032 as well. Affected file lib/silcutil/silcnet.c.
2034 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2035 Affected lib/silcutil/unix/silcunixnet.c.
2037 * Fixed ID rendering (at least on some platforms, not NetBSD)
2038 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2040 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Added silc_hash_public_key and silc_hash_public_key_compare
2043 functions to be used with SilcHashTable. They can be used to
2044 hash public keys and compare public keys in hash table. Affected
2045 file lib/silcutil/silcutil.[ch].
2047 * Added support for specifying multiple public keys for Client
2048 connection section in server configuration file. This makes it
2049 possible to accept multiple public keys from same host, or to
2050 make a section that accepts any incoming host, and have the
2051 accepted public keys listed in the section.
2053 Added functions silc_sever_[find/get]_public_key, added the
2054 support for this actually to all connection sections but only
2055 the Client section is currently allowed to specify multiple
2058 Affected files are silcd/server.c, server_internal.h,
2059 command.c, protocol.c, server_util.[ch], packet_receive.c.
2061 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2063 * Merged Irssi 0.8.2 from irssi.org CVS.
2065 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2067 * If silc_debug is TRUE, also output standard logging messages
2068 to stderr with the debug output.
2070 Made silc_log_reset_all() flushing all channels before returning.
2071 Also fixed some documentation typos.
2073 Affected files are lib/silcutil/silclog.[ch].
2075 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2077 * Fixed the server to check correctly the amount of connections
2078 from single host, by checking also the type of the connection.

2230 the SKE interface a bit.
2232 * Fixed padding problem in PKCS#1. The padding was not actually
2233 random since the random number generator was used incorrectly.
2234 This security bug affects only when encrypting with PKCS#1, and
2235 it is not currently used at all in SILC. SILC only use signing
2236 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2321 the connection configuration object from the SilcServerConnection
2322 object instead of finding it during the connecting phase.
2323 Added the configuration object to SilcServerConnection struct.
2324 Affected files silcd/server_internal.h, server.c.
2326 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2328 * Add the client on channel after it was resolved at the
2329 channel message receiving, and it was not already on the
2330 channel. Affected file lib/silcclient/client_channel.c.

2352 public key is set. If not set, public key is preferred.
2353 This has effect only when being initiator (responder will try
2356 Added support for authentication with passphrase and public key
2357 at the same time. The passphrase is tried first always since
2358 it is faster to check.
2360 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2362 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2408 * Fixed the file transfer's key agreement payload to include
2409 zero port also if the hostname is NULL because it could not
2412 Call file transfer monitor callback now also if error occurs
2413 during key agreement protocol.
2415 Changed the silc_client_file_send interface to return the
2416 SilcClientFileError instead of session id. The session ID
2417 is returned into pointer provided as argument.

2432 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2433 SILC_LOG_WARNING to give out Warning and not Error. Affected
2434 file lib/silcutil/silclog.c.
2436 * Fixed the channel message payload decryption in the function
2437 silc_channel_message_payload_decrypt to not modify the original
2438 buffer before it is verified that the message decrypted

2456 the table with foreach callback. The current entry may
2457 become invalid in the callback but it was referenced after
2458 the callback returned.
2460 Do not allow auto rehashing of hash table during the
2461 silc_hash_table_foreach operation, for same reasons as it is
2462 not allowed for SilcHashTableList. Affected files are
2463 lib/silcutil/silchashtable.[ch].
2465 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2489 * Fixed a bug in hash table tarversing. While the hash table
2490 is traversed with SilcHashTableList the table must not be
2491 rehashed. It is now guaranteed that auto rehashable tables
2492 are not rehashed while tarversing the list. Also defined that
2493 silc_hash_table_rehash must not be called while tarversing
2494 the table. Added function silc_hash_table_list_reset that must
2495 be called after the tarversing is over. The affected files are
2496 lib/silcutil/silchashtable.[ch].
2498 * Changed all hash table traversing to call the new
2499 silc_hash_table_list_reset in server and in client library.
2501 * Added function silc_client_on_channel to return the
2502 SilcChannelUser entry if the specified client entry is joined
2503 on the specified channel. This is exported to application as
2504 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2512 * Fixed the WHOWAS command's reply sending to support the
2513 lists correctly. Affected file silcd/command.c.
2515 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2517 * When sending JOIN command to router for processing the
2518 sender's old command identifier was not saved back to the
2519 sender's command context, fixed now. The affected file is
2522 * Create the key in JOIN command of the router did not return
2523 the channel key, added check for this. Affected file is
2526 * Fixed a channel ID update bug in JOIN command reply. Do
2527 not directly upgrade the ID but call the function
2528 silc_idlist_replace_channel_id if the ID was changed.
2529 Affected file silcd/command_reply.c.
2531 * Fixed memory leaks from command calling if it would fail.
2532 Affected file silcd/command.c.

2559 functions. Affected file silcd/server.c.
2561 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2562 which ID was changed. This way the router will send the
2563 user list for the channel again, and server won't be in
2564 desync in some rare circumstances. Affected file is
2565 silcd/packet_receive.c.
2567 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2603 * Raised the default connection-retry count from 4 to 7 in
2604 server. Affected file silcd/server.h.
2606 * Cancel any possible reconnect timeouts when we start the
2607 key exchange. Affected file silcd/server.c.
2609 * Do not reconnect on connection failure when SCONNECT was
2610 given. Affected files silcd/server.[ch].
2612 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2614 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2616 * Fixed the NICK command to always give the unformatted
2617 nickname to the one giving the NICK command. If unformatted
2618 nickname is cached already it will be formatted and the
2619 local entry will always get the unformatted nickname.
2620 Affected file lib/silcclient/idlist.c.
2622 * Fixed some double frees from client library commands.
2623 Affected file is lib/silcclient/command.c.
2625 * Fixed CUMODE command in server to assure that no one can
2626 change founder's mode than the founder itself, there was a
2627 little bug. Affected file silcd/command.c.
2629 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2631 * Removed the SilcClientCommandDestructor from the client
2632 libary, it is not needed anymore. Affected files are
2633 lib/silcclient/silcapi.h, command[_reply].[ch],
2634 client_notify, idlist.c.
2636 * Fixed GETKEY command to first resolve client, and then
2637 resolve the server only if the client was not found, instead
2638 of resolving both at the same time. Affected file is
2639 lib/silcclient/command.c.
2641 * Added silc_client_start_key_exchange_cb and lookup the
2642 remote hostname and IP address before starting the key
2643 exchange with server. The affected file is
2644 lib/silcclient/client.c.
2646 * The server's public key is now saved using the IP address
2647 of the server and not the servername for the filename.
2648 The hostname public key filename is checked as an fall back
2649 method if the IP address based filename is not found.
2651 Fixed the GETKEY command to save the fetched server key
2652 in correct filename.
2654 Print the remote server's hostname now when new key is
2655 received during connection process. Affected file is
2656 irssi/src/silc/core/client_ops.c.
2658 * Return always our own public key to the client if it asks
2659 for it with GETKEY command. Affected file silcd/command.c.
2661 * Removed the use_auto_addr variable from default config
2662 file since it was in wrong section. Affected file is
2665 * Fixed TOPIC_CHANGE notification to not route it when it
2666 was sent using silc_server_send_notify_to_channel function.
2667 Affected file silcd/command.c.
2669 * Fixed silc_server_send_notify_kicked to send the kicker's
2670 Client ID also, it was missing. Affected files are
2671 silcd/command.c, silcd/packet_send.[ch].
2673 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2675 * Do not save client history information in SERVER_SIGNOFF.
2676 Fixes the bug in normal server that it does not detect
2677 the client becoming valid after the server becomes back
2678 online. Affected file silcd/server_util.c.
2680 * Added `sock_error' field into the SilcSocketConnection
2681 context. When error occurs during socket operation (read
2682 or write) the error is saved. Added also new function
2683 silc_socket_get_error to return human readable socket error
2684 message. Affected files are lib/silcutil/silcsockconn.[ch],
2685 lib/silcutil/unix/silcunixsockconn.c, and
2686 lib/silcutil/win32/silcwin32sockconn.c.
2688 * The server now prints the socket error message in the
2689 signoff for client. Affected file silcd/server.c.
2691 * Fixed the `created' channel information sending from router
2692 to server in JOIN command. Checks now whether the channel
2693 really was created or not and set it according that.
2695 Fixed the JOIN command to use the client entry's current
2696 ID during the joining procedure instead of the one it sent
2697 in the command (it is checked though), since it can change
2698 between the packet processing and command processing, and
2699 would just case unnecessary pain in the client end. Affected
2700 file silcd/command.c.
2702 * Fixed a channel key payload sending to use correct channel
2703 ID when the server was forced to change the channel's ID by
2704 router. Router sent the key payload with the old Channel ID.
2705 Affected file silcd/packet_receive.c.
2707 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2709 * Call silc_server_save_channel_key only if the key payload
2710 was provided in the JOIN command's command reply. Affected
2711 file silcd/command_reply.c.
2713 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2715 * Fixed silc_mp_sizeinbase to return the value correctly with
2716 MPI. Affected file lib/silcmath/mp_mpi.c.
2718 * Fixed the stop_server signal to correctly stop the scheduler
2719 and gracefully stop the server when SIGTERM or SIGINT signals
2720 are received. Affected file silcd/silcd.c.
2722 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2724 * Simple handling of TERM and HUP signals. Also added some log
2725 flushing call around. Affected file is
2728 * Fixed small bugs in silclog.c. Now buffering output will take
2729 effect after 10 seconds since startup: This will ensure that
2730 no important startup messages are lost. Also output redirection
2731 will preserve original format ([Date] [Type] message).
2732 Affected file is lib/silcutil/silclog.c.
2734 * Added two options to the config file, in the logging section:
2735 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2736 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2738 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2740 * Do not print the warning about log files not being initialized
2741 more than once to avoid excess logging. Affected file is
2742 lib/silcutil/silclog.c.
2744 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2745 the SIM copying in make install in Makefile.am.pre.
2747 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2749 * Rewritten silclog APIs. Globally interesting changes follows:
2750 silc_log_set_files() changed to silc_log_set_file().
2751 silc_log_set_callbacks() changed to silc_log_set_callback().
2752 ROBOdoc documented silclog header file.
2753 SilcLogCb now returns bool to wether inihibit the default
2754 handler or not (to keep the old behaviour return always TRUE).
2755 The new APIs should also fix the problem of the
2756 silcd_error.log file that was written in the current directory.
2759 Log files streams will remain opened after silc_log_set_file()
2760 call, means less CPU usage notably on high traffic servers.
2761 File streams are now full buffered, and flushed to the disk
2762 every 5 minutes, lesses HD activity and CPU usage.
2763 Messages can be redirected, allowing admins to configure
2764 one single logfile for all server messages.
2765 the silc_log_quick global variable to activate fast-logging.
2766 Affected files lib/silcutil/silclog.[ch]
2768 * Changed some code to conform new silclog APIs. Affected
2769 files are doc/example_silcd.conf.in, silcd/server.c
2770 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2773 * Fixed a memory leak that could occur in some situations.
2774 Affected file silcd/serverconfig.c.
2776 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2778 * Added the silc_client_del_client to remove the client from
2779 all channels as well. Affected file lib/silcclient/idlist.c.
2781 * Fixed the client library to correctly remove the client
2782 from all channels when the client entry is being destroyed.
2783 Affected file lib/silcclient/client_notify.c, command.c.
2785 * Added auto-nicking support to the client library. If the
2786 applicatio now sets client->nickname it will be sent to the
2787 server after connecting by the library. This way for example
2788 SILCNICK (or IRCNICK) environment variables will have effect
2789 and always change the nickname automatically to whatever
2790 it is wanted. Affected file lib/silcclient/client.[ch].
2792 * Renamed silc_server_command_bad_chars to the
2793 silc_server_name_bad_chars and moved it to the
2794 silcd/server_util.[ch]. Added also new function
2795 silc_server_name_modify_bad to return nickname that
2796 includes bad characters as new nickname without those
2797 bad characters. This check and modify is now used in
2798 silc_server_new_client when the username is initially set
2799 as nickname, so it must be checked to be valid nickname.
2800 Affected file silcd/packet_receive.c.
2802 * The nickname length is now taken from the packet for real
2803 and not trusted to strlen() since it clearly can return
2804 wrong length for nickname including bad characters. This
2805 also applies to channel names. Affected file silcd/command.c.
2807 * Removed the lib/silcsilm/modules directory. Modules are now
2808 compiled into the lib/silcsim. Fixed the copying of the
2809 modules to follow symbolic links in Makefile.am.pre.
2811 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2813 * Fixed silc_string_regexify list creation. Fixes bugs with
2814 BAN and INVITE commands in server. The affected file is
2815 lib/silcutil/unix/silcunixutil.c.
2817 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Removed the command destructor entirely from the server's
2820 command and command reply routines. It is not needed, and
2821 its usage was buggy and caused crashes. Affected files are
2822 silcd/command[_reply].[ch].
2824 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Cancel protocol and NULL sock->protocol if timeout
2827 occurred during protocol. Affected file silcd/server.c.
2829 * Cancel protocol timeouts always before calling the final
2830 callback, to assure that after final callback is called
2831 no other state will be called for the protocol anymore.
2832 Affected file silcd/protocol.c.
2834 * Print error log if incoming connection configuration could
2835 not be found. Affected file silcd/server.c.
2837 * Fixed JOIN command to correctly save the founder mode
2838 to the client on normal SILC server, when the channel
2839 was created by the router. Affected file silcd/command.c.
2841 * Fixed LIST command (hopefully) to send correct reply
2842 packets. Affected file silcd/command.c.
2844 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * The silc_packet_receive_process now returns FALSE if the
2847 read data was invalid packet, and TRUE if it was ok.
2849 The server now checks that if unauthenticated connection
2850 sends data and its processing fails the server will close
2851 the connection since it could be a malicious flooder.
2853 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2855 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Make sure the warning about error opening a log file is
2858 printed only once and not everytime it fails (produces
2859 too much useless log). Affected file lib/silcutil/silclog.c.
2861 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2863 * Made the silc_server_daemonise() function more readable.
2864 Affected file silcd/server.c.
2866 * Pid file is now optional, the user may comment it out from
2867 the config file. Removed define SILC_SERVER_PID_FILE, we
2868 don't need a default any longer. Affected file
2869 configure.in.pre, lib/Makefile.am.pre.
2871 * Make some use of the pid file. The server now dies at startup
2872 if it detects a valid pid file on his path. The server would
2873 die anyway in this circumstance, because of the bind() failure.
2874 Affected file silcd/silcd.c.
2876 * No longer compiling lib/dotconf.
2878 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Fixed JOIN command parsing not to crash. Affected file
2881 lib/silcclient/command.c.
2883 * Fied the NICK_CHANGE notify to add the new client entry
2884 even it is resolved. This removes an <[unknown]> nick
2885 thingy bug in the client. Affected file is
2886 lib/silcclient/client_notify.c.
2888 * Do not try to allocate 0 bytes (efence does not like it)
2889 in lib/silccore/silccomand.c when encoding payload.
2891 * Do not take IRCNICK as nickname in Irssi SILC client since
2892 it is not possible to set nickname before hand connecting
2893 the server (TODO has an entry about adding auto-nicking
2896 * Changed the silc_server_command_pending to check whether
2897 there already exists an pending entry with the specified
2898 command, command identifier and pending callback. This is
2899 to fix IDENTIFY and WHOIS related crashes that may register
2900 multiple pending commands with same identifier. Affected
2901 file silcd/command.c.
2903 * Fixed the server to reconnect to the router even if it
2904 was already reconnecting and EOF was received. This to
2905 fix a possibility that the server wouldn't ever try to
2906 auto-reconnect to the router. Affected file silcd/server.c.
2908 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Fixed the server's password authentication to use the
2911 length of the locally saved password, and not the one
2912 sent in the packet. Affected file silcd/protocol.c.
2914 * Fixed same password authentication problem in the
2915 Authentication Payload handling routines in
2916 lib/silccore/silcauth.c.
2918 * Yet another password authentication problem fixed with
2919 channel password handling in silcd/command.c.
2921 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * If first character of string in silc_parse_userfqdn is '@'
2924 then do not parse it. Affected file is
2925 lib/silcutil/silcutil.c.
2927 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Fixed minor bug in IDENTIFY command reply sending, which
2930 caused various weird problems during JOIN when it was
2931 resolving names for users. Affected file silcd/command.c.
2933 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Fixed the IDENTIFY command reply sending to chech better valid
2936 clients. It was possible to send incomplete list of replies.
2937 Affected file silcd/command.c.
2939 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Added silc_client_command[s]_[un]register functions now to
2942 dynamically register the commands in client library. Removed
2943 the static table of commands. This allows the client library
2944 to call commands without causing the application to know about
2945 what commands library has called.
2947 Removed the INFO command reply kludge to detect when the command
2948 was called by library. Now library use its own command reply
2949 function for INFO command.
2951 Added function silc_client_command_call to call a command.
2952 Application can use it to call command, not access the structure
2955 Now all commands that are sent by the client library (not
2956 explicitly sent by application) use own command reply functions.
2958 Affected files around lib/silcclient/ and in
2959 irssi/src/silc/core/.
2961 * Fixed the WHOIS command reply sending to chech better valid
2962 clients. It was possible to send incomplete list of replies.
2964 Fixed the WHOIS and IDENTIFY to send the request to router
2965 if normal server did not do it and did not find any results.
2967 Affected file silcd/command.c.
2969 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Moved the internal data from SilcClient context into its
2972 own file, not accesible to application. Affected files
2973 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2974 and other files in client library.
2976 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Added doc/examples installation target in Makefile.am.pre.
2981 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2984 commands the found client entry will be removed from the
2985 cache, after notifying application about the error. Affected
2986 file lib/silcclient/command_reply.c.
2988 * Changed the /MSG to check for exact nickname user gave, and
2989 not let `nick' match `nick@host' if it is only one found. Now,
2990 user must type the exact nickname (like nick@host2) even if
2991 there are no more than one same nicks found. This is to avoid
2992 a possibility of sending nickname to wrong nickname since
2993 `nick' could match `nick@host'. Affected file is
2994 irssi/src/core/silc-servers.c.
2996 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Do not print "you are now server operator" or similar when
2999 giving /away command. Affected files are
3000 irssi/src/silc/core/client_ops.c, silc-servers.h.
3002 * Made the silc_server_command_pending_error_check to send
3003 the same command reply payload it received back to the
3004 original sender of the command. This way all arguments
3005 that was received by the server will be received by the
3006 client too. Affected file silcd/command.c.
3008 * Added the silc_idcache_add to return the created cache entry
3009 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3011 * Add global clients to expire if they are not on any channel.
3012 This is because normal server will never know if they signoff
3013 if they are not on any channel. The cache expiry will take
3014 case of these entries. This is done by normal servers only.
3015 The affected files are silcd/command_reply.c,
3016 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3018 * If server receives invalid ID notification for WHOIS or
3019 IDENTIFY and the ID exists in the lists, it is removed.
3020 Affected file silcd/command_reply.c.
3022 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3023 in client then client entry that it matches is searched and
3024 the nickname is printed on the screen for user. Affected
3025 file irssi/src/silc/core/client_ops.c.
3027 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Use cache entry expire time in the LIST command reply to
3030 purge old entries from the cache after the LIST command
3031 reply has been received. This way we don't have non-existent
3032 entries in the cache for too long. Affected file is
3033 silcd/command_reply.c.
3035 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * If we are normal server, and we've not resolved client info
3038 in WHOIS or IDENTIFY from router, and it is global client,
3039 we'll check whether it is on some channel. If it is not
3040 then we cannot be sure about its validity and will resolve it
3041 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3042 file silcd/command.c.
3044 * Search channel by name (if possible) rather than by ID
3045 in IDENTIFY command's command reply. Affected file is
3046 silcd/command_reply.c.
3048 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3051 Updated specs and implemented it. Affected file silcd/command.c,
3052 silcd/packet_send.c and silcd/packet_receive.c.
3054 * Implemented the <founder auth> payload handling in the JOIN
3055 command. If provided all conditions for channel joining
3056 except requirement to provide correct passphrase can be
3057 overrided by the channel founder. Updated the protocol specs.
3058 Affected file silcd/command.c.
3060 Added support for founder auth in JOIN command in client
3061 library. Fixed the parsing of the JOIN command now to support
3062 all options as they should be. The affected file is
3063 lib/silcclient/command.c.
3065 * Optimized the WHOIS and IDENTIFY commands to send the request
3066 to router only if it includes nicknames or other names. If
3067 they include only IDs then check the local cache first before
3068 routing. Affected file is silcd/command.c.
3070 * Added channels topic announcements. Affected file is
3071 silcd/packet_receive.c and silcd/server.c.
3073 * Fixed the silc_server_send_notify_topic_set to really destine
3074 the packet to channel. Affected file silcd/packet_send.c.
3076 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3077 library. Affected file lib/silcclient/client_notify.c.
3079 * Added UMODE announcements. Affected file silcd/server.c.
3081 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Memory leak fixes in:
3085 lib/silcutil/silcsockconn.c
3086 lib/silcske/silcske.c
3087 lib/silcske/groups.c
3089 lib/silccrypt/silcpkcs.c
3090 lib/silccore/silccommand.c
3091 lib/silccore/silcidcache.c
3096 * ROBOdoc documented the lib/silcske/groups.h file and a
3097 bit changed the interface for better.
3099 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3101 * Update the client entry context in the ID cache after
3102 nick change. Affected file lib/silcclient/command.c.
3103 Fixes the CUMODE command when regaining founder privileges,
3104 and a little WHOIS problem.
3106 * Fixed silc_net_gethostbyname to correctly call the
3107 inet_ntop. Affected file lib/silcutil/silcnet.c.
3109 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3111 * Added IPv6 support checking to the configure.in.pre, added
3112 also --enable-ipv6 option to override the check. Affected
3113 file configure.in.pre.
3115 * The silc_thread_create now calls the start function
3116 directly if threads support is not compiled in. Removes
3117 ugly #ifdef's from generic code. Affected files are
3118 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3120 * Added silc_net_gethostby[name/addr]_async to asynchronously
3121 resolve. Affected files are lib/silcutil/silcnet.[ch].
3123 * Added support for rendering IPv6 based server, client and
3124 channel IDs. Affected file lib/silcutil/silcutil.c.
3126 * Added support for creating IPv6 based server IDs. Affected
3127 file is silcd/serverid.c.
3129 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3131 * Added silc_net_gethostby[addr/name] into the
3132 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3133 routines. Added silc_net_is_ip[4/6]. Affected file is
3134 lib/silcutil/unix/silcunixnet.c. All routines that take
3135 address as argument now supports both IPv4 and IPv6 addresses.
3137 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3139 * Fixed LIST command reply sending in server. Affected file
3142 * Server now sends the kicker's client ID in the KICK notify
3143 to the kicked client. Affected file silcd/command.c.
3145 * The client library now parses the kickers client ID and
3146 UI displays it. Affected files lib/silcclient/client_notify.c
3147 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3149 * Made all payload parsing function prototypes consistent.
3150 They all take now const unsigned char * and uint32 pair as
3151 the payload data instead of SilcBuffer. Changes all around
3152 the source tree. Other unsigned char* -> const unsigned char*
3153 changes around the tree as well.
3155 * Optimized SFTP client and server packet sending not to
3156 allocate new buffer for each packet but to recycle the
3157 first allocated buffer. Affected files are
3158 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3160 * Optimized the SFTP client to use SilcList instead of
3161 SilcDList for requests, because it is faster. Affected file
3162 is lib/silcsftp/sftp_client.c.
3164 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3165 into lib/silccore/silcid.[ch].
3167 Renamed silcpayload.[ch] into silcargument.[ch].
3169 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * If client entry is deleted with active key agreement
3172 session, abort the session.
3174 The silc_client_abort_key_agreement now calls the completion
3175 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3177 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3180 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Don't use __restrict in older GCC's. Affected file is
3183 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3185 * silc_net_localhost now attempts to reverse lookup the
3186 IP/hostname. Affected file lib/silcutil/silcnet.c.
3188 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3189 command. It can be used to gain founder privileges at
3190 the same time when joining the channel.
3192 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3193 kicker's client ID as well. Updated protocol specs.
3195 Defined that the server must send SILC_COMMAND_IDENTIFY
3196 command reply with error status to client who sent
3197 private message with invalid client ID.
3199 Updated the protocol specification.
3201 * Added silc_server_send_command_reply to send any
3202 command reply. Affected file silcd/packet_send.[ch].
3204 * Added silc_id_payload_encode_data to encode ID payload
3205 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3207 * The server now send IDENTIFY command reply with error
3208 status if client ID in private message is invalid. Affected
3209 file silcd/packet_receive.c.
3211 * Save the server key file with server's IP address in
3212 the filename instead of hostname. The affected file is
3213 irssi/src/silc/core/client_ops.c.
3215 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3220 * Added libtool support for compiling shared objects in
3221 lib/silcsim. Affected file configure.in.pre and
3222 lib/silcsim/Makefile.am. Original patch by cras.
3224 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Pid file configuration, and server's config file fixes
3227 patch by toma. Updated CREDITS file.
3229 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Fixed silc_client_channel_message to not try to decrypt
3232 the message twice if it resolved the destination client
3233 information. This could cause of dropping one channel
3234 message. Affected file lib/silcclient/client_channel.c.
3236 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3239 lib/silcclient/client.c. This function is used when the SILC
3240 Client is run under some other scheduler, or event loop or
3241 main loop. On GUI applications, for example this may be
3242 desired to used to run the client under the GUI application's
3243 main loop. Typically the GUI application would register an
3244 idle task that calls this function multiple times in a second
3245 to quickly process the SILC specific data.
3247 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3249 * Fixed silc_server_drop() for dropping the supplementary
3250 groups as well, this could cause a security hole on some
3253 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3258 * Write PID file after dropping privileges. Added -F option
3259 to run server on foreground. A patch by debolaz.
3260 Affected files silcd/server.c, silcd/silcd.c.
3262 * Fixed MOTD to return the MOTD file server name. Affected
3263 file silcd/command.c.
3265 * Added INFO command reply handling to the Irssi SILC Client.
3266 Affected file irssi/src/silc/core/client_ops.c.
3268 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Fixed the silc_idcache_list_* routines to really support
3271 the dynamic list. Fixes a crash. Affected file is
3272 lib/silccore/silcidcache.c.
3274 * Fixed the LIST command reply to really call LIST command's
3275 pending callbacks. Affected file silcd/command_reply.c.
3277 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Update conn->local_entry->nickname after giving NICK
3280 command. Affected file lib/silcclient/command.c.
3282 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3284 * Added the [pid] option to the silcd configuration file
3286 Affected files: serverconfig.[ch] and silcd.c
3288 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Save fingerprint in WHOIS command reply in server.
3291 Affected file silcd/command_reply.c.
3293 * Fixed NICK commands pending callback registration.
3294 Affected file lib/silcclient/command.c.
3296 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3298 * Use ++server->cmd_ident when sending commands in server,
3299 instead of random number. Affected file silcd/command.c.
3301 * Fixed GETKEY command reply to call actually GETKEY pending
3302 command callbacks. Affected file silcd/command_reply.c.
3304 * A bit stricter check for nicknames. Check for same nickname
3305 in NICK command also. Affected file silcd/command.c.
3307 * Do not call INFO command everytime client ID changes, only
3308 during first connecting. Affected file lib/silcclient/client.c.
3310 * Set the new nickname only after successful command reply for
3311 NICK command is returned by server. Affected file
3312 lib/silcclient/command.c.
3314 * Remove nicknames from nicklist during server_signoff notify.
3315 Should fix /NAMES bit more. The affected file is
3316 irssi/src/silc/core/silc-channels.c.
3318 * Added `fingerprint' field to the SilcIDListData in the
3319 silcd/idlist.h to hold the fingerprint of the client's
3322 Send the fingerprint of the client's public key in WHOIS
3325 Affected files silcd/command.c, and silcd/idlist.[ch].
3327 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3328 create fingerprint from given data.
3330 * Show the fingerprint of the client's public key in WHOIS.
3331 Affected files irssi/src/module-formats.[ch] and
3332 irssi/src/silc/core/client_ops.c.
3334 * Format the multiple same nicknames also during JOIN and
3335 NICK_CHANGE notifys. Affected file is
3336 lib/silcclient/client_notify.c.
3338 * Do not print error on screen for invalid private message
3339 payload since it can come if someone is sending private
3340 messages with wrong key. Affected file
3341 lib/silccore/silcprivate.c.
3343 * Fixed multiple concurrent /PING crash. Affected file
3344 lib/silcclient/command.c.
3346 * Changed the wrong ID encoding. All IP addresses must be
3347 in MSB first order in encoded format. They were encoded
3348 wrong and was in LSB format. Affected files are
3349 silcd/serverid.c, lib/silcutil/silcutil.c.
3351 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3353 * Call the `connect' client operation through the scheduler
3354 in case of error. Affected file lib/silcclient/client.c.
3356 * Call the `failure' client operation even if the error
3357 occurred locally during a protocol. Affected file is
3358 lib/silcclient/protocol.c.
3360 * Added support of sending LIST command to router from normal
3361 server. This way normal server can get list of all channels
3362 in the network too. Fixed the channel list sending in the
3363 server too. Affected files are silcd/command.c, and
3364 silcd/command_reply.[ch].
3366 * Added silc_server_update_channels_by_server and
3367 silc_server_remove_channels_by_server. They are used during
3368 disconnection of primary router and in backup router protocol.
3369 Affected file silcd/server_util.[ch], silcd/server.c and
3370 silcd/server_backup.c.
3372 * Fixed channel adding to global list in IDENTIFY command
3373 reply in server. Affected file silcd/command_reply.c.
3375 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3377 * If the incoming packet type is REKEY or REKEY_DONE process
3378 that packet always synchronously. Fixes yet another MAC
3379 failed error on slow (dialup) connections. Affected file
3380 lib/silcclient/client.c and silcd/server.c.
3382 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3384 * Call check_version SKE callback for initiator too. Affected
3385 file lib/silcske/silcske.c.
3387 * Implemented fix for security hole found in the SKE that was
3388 fixed in the specification few days back; the initiator's
3389 public key is now added to the HASH value computation.
3390 Added backwards support for the old way of doing it too, for
3391 old clients and old servers. Affected file is
3392 lib/silcske/silcske.c.
3394 * Enabled mutual authentication by default in SKE. If initiator
3395 is not providing mutual authentication the responder will
3396 force it. This will provide the proof of posession of the
3397 private key for responder. The affected files are
3398 lib/silcclient/protocol.c and silcd/protocol.c.
3400 * Do not cache anymore the server's public key during SKE.
3401 We do mutual authentication so the proof of posession of
3402 private key is done, and if the server is authenticated in
3403 conn auth protocol with public key we must have the public
3404 key already. Affected file silcd/protocol.c.
3406 * Added new global debug variable: silc_debug_hexdump. If
3407 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3408 file lib/silcutil/silclog.[ch].
3410 * Fixed compilation warning due to char * -> const char *.
3411 Affected files lib/silcutil/silcnet.h, and
3412 lib/silccore/silcauth.[ch].
3414 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Fixed CMODE command when new channel key was created. If
3417 the creation failed the old key was removed. Next time giving
3418 same command would crash the server since the old key was
3419 freed already. Affected file silcd/command.c.
3421 * Fixed the silc_server_announce_get_channels to not crash
3422 on reconnect. Affected file silcd/server.c.
3424 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3426 * Added silc_log_set_debug_string function to set a regex
3427 string to match for debug output. Only the function names,
3428 or filenames matching the given debug string is actually
3429 printed. This way it is possible to filter out those debug
3430 strings that user is not interested in.
3432 Fixed a bug in silc_string_regexify.
3434 Affected files lib/silcutil/silclog.[ch], and
3435 lib/silcutil/unix/silcunixutil.c.
3437 * Changed the -d options in both server and Irssi SILC client
3438 to take the debug string as argument. Affected files
3439 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3441 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Added silc_hash_babbleprint to create a Bubble Babble
3444 Encoded fingerprint. The encoding is developed by Antti
3445 Huima (draft-huima-babble-01.txt), and it creates human
3446 readable strings out of binary data. Affected file
3447 lib/silccrypt/silchash.[ch].
3449 * Print the babble print now in addition of fingerprint as well
3450 in Irssi SILC client. Affected files are
3451 irssi/src/fe-common/silc/module-formats.[ch],
3452 irssi/src/fe-common/silc/core/client_ops.c.
3454 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Fixed a security problem found in SKE. The initiator's
3457 public key too is now added to the HASH hash value creation
3458 which is signed by the responder to create the SIGN value.
3459 This will prevent anyone in the middle to lie to the responder
3460 about the initiator's public key. If this is done now, the
3461 man in the middle will get caught. Updated the protocol
3464 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Better installation directory handling. Configure module
3467 paths and other paths automatically to example_silc* files
3468 in doc/. A patch by toma.
3470 * Fixed compiler warning from MPI library, and from SILC RNG.
3473 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3474 It can be configured with ./configure. A patch by toma.
3476 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Find correct make to use in prepare-clean. A patch by
3479 toma. Affected file prepare-clean.
3481 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3483 * Added irssi variables use_auto_addr, auto_bind_ip,
3484 auto_bind_port and auto_public_ip.
3486 * Changed the interface for silc_client_send_key_agreement
3487 in lib/silcclient/silcapi.h
3491 irssi/src/silc/core/silc-core.c
3493 lib/silcclient/silcapi.h
3494 irssi/src/silc/core/silc-channels.c
3495 lib/silcclient/client_keyagr.c
3498 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Added silc_pkcs_public_key_compare to compare two
3501 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3503 * Check that the client who set the founder mode on the
3504 channel is the same client that is giving the founder
3505 mode to itself. It is done by comparing the saved public
3506 key (it is saved even in the authentication is passphrase).
3507 Affected file silcd/command.c.
3509 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * Do not process packet for disconnected socket connection.
3512 Affected file lib/silccore/silcpacket.c.
3514 * Process the DISCONNECT packet through scheduler in the
3515 client library. Affected file lib/silcclient/client.c.
3517 * Fixed the silc_client_packet_parse to not to increase
3518 the packet sequence number if the conn->sock and the
3519 current socket connection is not same. This can happen
3520 for example during key agreement when the conn includes
3521 multiple socket connections (listeners). Affected file
3522 lib/silcclient/client.c.
3524 * The sender of the file transfer request now provides also
3525 the pointer (listener) for the key exchange protocol. If
3526 the listener cannot be created then it sends empty key
3527 agreement and lets the receiver provide the listener.
3529 Added `local_ip' and `local_port' arguments to the
3530 silc_client_file_send. If they are provided they are used,
3531 if not then it will attempt to find local IP address, if
3532 not found or bind fails then the remote client will provide
3535 Affected files are lib/silcclient/client_ftp.c and
3536 lib/silcclient/silcapi.h.
3538 * Extended the FILE SEND command to support defining the
3539 local IP and port for key exchange listener. They are
3540 optional. Affected file irssi/src/silc/core/silc-servers.c.
3542 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3544 * Defined to WHOIS command reply the sending of fingerprint
3545 of the client's public key (if the proof of posession of the
3546 corresponding private key is verified by the server).
3547 Updated to the protocol specification.
3549 * Added support of receiving the client's public key's
3550 fingerprint in command reply in client library. Affected
3551 file is lib/silcclient/command_reply.c, and
3552 lib/silcclient/idlist.[ch].
3554 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Do not send over 128 chars long nickname to the server
3557 in NICK command. Affected file lib/silcclient/command.c.
3559 * Do not send over 256 chars long channel names to the server
3560 in JOIN command. Affected file lib/silcclient/command.c.
3562 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Assure that silc_server_close_connection cannot be called
3565 twice for same socket context. Affected file is
3568 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Send error message to application if opening file for
3571 writing during file transfer fails. Affected file is
3572 lib/silcclient/client_ftp.c.
3574 Remove all file transfer sessions for a client that we're
3575 removing from ID cache.
3577 Affected file is lib/silcclient/client_ftp.c.
3579 * Fixed silc_net_addr2bin to return correct address. Affected
3580 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3582 * Fixed file transfer session removing on signoff notify.
3583 Affected file irssi/src/silc/core/silc-servers.c.
3585 * Added the SilcClientFileError to be returned in the monitor
3586 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3587 Affected file lib/silcclient/silcapi.h.
3589 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Fixed a crash in silc_client_ftp_free_sessions and
3592 silc_client_ftp_session_free_client. Affected file
3593 lib/silcclient/client_ftp.c.
3595 * Added `disabled' field in the SilcChannelEntry in the server
3596 to indicate if the server entry is disabled. Affected file
3597 silcd/idlist.h, silcd/command[_reply].c.
3599 * SILC server adds now /var/run/silcd.pid everytime it is
3600 started. Affected file silcd/silcd.c.
3602 * Added silc_server_packet_send_clients to send a packet to
3603 the provided table of client entries. Affected file
3604 silcd/packet_send.[ch].
3606 * Fixed a crash in client resolving in client_prvmsg.c in
3607 client library. Affected file lib/silcclient/client_prvmsg.c.
3609 * Do not actually remove the client directly from ID cache
3610 during SERVER_SIGNOFF, but invalidate it. This way we
3611 preserve the WHOWAS info for the client. Affected file
3612 silcd/server_util.c.
3614 * Fixed SERVER_SIGNOFF notify handling in the server. The
3615 server is now able to process incoming SERVER_SIGNOFF notify
3616 for a server that it doesn't even know about. It will remove
3617 the clients provided in the notify. Affected file
3618 silcd/packet_receive.c.
3620 * Check for partial packet in data queue after every packet that
3621 was found from the queue. Return and wait for more data if
3622 there is partial data in queue. Affected file is
3623 lib/silccore/silcpacket.c.
3625 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Added SilcClietFileError enum to indicate error in
3628 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3629 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3630 Affected files lib/silcclient/silcapi.h and
3631 lib/silcclient/client_ftp.c.
3633 * Check that newsize in silc_buffer_realloc is larger than
3634 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3636 * Added better monitor of file transfers. It now monitors
3637 key agreement protocol during the file transfer too. Added
3638 error reporting too. Affected files
3639 irssi/src/silc/core/silc-servers.c,
3640 irssi/src/fe-common/silc/module-formats.[ch].
3642 * Wrote a help file for FILE command.
3644 * Added silc_rng_global_get_byte_fast to get not-so-secure
3645 random data as fast as possible. Random data is read from
3646 /dev/urandom if available and from the SILC RNG if not
3647 available. It is used in padding generation. Affected file
3648 lib/silccrypt/silcrng.[ch].
3650 * All packets in client library are now processed synchronously.
3651 Optimized packet processing a lot. Affected file
3652 lib/silcclient/client.c.
3654 * All server connection packets are processing synchronously
3655 now in server, to optimize packet processing. Affected file
3658 * Include files are installed now only in Toolkit distribution
3659 if make install is given. Affected files: all Makefile.am's.
3661 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3663 * Assure that silc_client_notify_by_server_resolve does not
3664 resolve the client information multiple times. If it cannot
3665 be found by the first it cannot be found at all. Affected
3666 file lib/silcclient/client_notify.c.
3668 * Fixed WHOWAS command reply calling. Affected file
3669 lib/silcclient/command_reply.c.
3671 * Removed all references to silc_idlist_get_client from the
3672 Irssi SILC client since that call is internal call used by
3673 the library. The Irssi SILC client will use now client
3674 retrieval functions found in silcapi.h.
3676 * Fixed a bug in resolving nickname info before sending
3677 private message. It used freed memory. Affected file
3678 irssi/src/silc/core/silc-servers.c.

3699 * Added silc_net_localip to return local host's IP address.
3700 Affected file lib/silcutil/silcnet.[ch].
3702 * If key exchange or rekey protocol is active for a connection
3703 parse all packets syncronously since there might be packets
3704 in packet queue that we are not able to process without first
3705 processing packets before them. Affected file silcd/server,
3706 lib/silcclient/client.c.
3708 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3709 whether library should continue processing the packet.
3710 Affected file lib/silccore/silcpacket.h.

3741 lib/silcutil/silcutil.[ch].
3743 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Resolve the client info when received private message or
3746 channel message for a client which nickname we don't know.
3747 Affected files lib/silcclient/client_prvmsg.c and
3748 lib/silcclient/client_channel.c.

3756 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3757 is incomplete and is being resolved, it won't be resolved
3760 Make sure also that USERS command reply does not resolve
3761 twice information. Affected file is
3762 lib/silcclient/command_reply.c.
3764 Make sure that silc_client_get_clients_by_list does not
3765 resolve twice same information.
3767 * Check for valid client->id in the silc_server_free_client_data.
3768 Affected file silcd/server.c.
3770 * Fixed /GETKEY nick@server not to crash if the server entry
3771 is not found. Affected file lib/silcclient/command.c.
3773 * Fixed the silc_server_check_cmode_rights to check the

3779 Affected file silcd/command.c.
3781 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Call the silc_server_udpate_servers_by_server in the
3784 primary router that comes back online in the backup resuming
3785 protocol. Otherwise it routes packets wrong. Affected file
3786 silcd/server_util.[ch], silcd/server_backup.c.
3788 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3791 lib/silcutil/silcbuffmt.[ch].
3793 * Redefined the SILC packet header to include the padding
3794 length. Affected file lib/silccore/silcpacket.[ch].
3796 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3797 length for maximum padding up to 128 bytes). Affected
3798 file lib/silccore/silcpacket.h.
3800 * Removed all backwards support for old 0.5.x MAC thingies.
3801 The SILC packet header change makes it impossible to be
3802 backwards compatible.
3804 * Send the ENDING packet with timeout in the backup resuming
3805 protocol. This is to assure that all routers has connected
3806 to the primary router. Affected file silcd/server_backup.c.
3808 * Changed the RNG to take the first IV from random data. It
3809 used to take it from zero actually. Changed the RNG also
3810 to use /dev/urandom during session. /dev/random is used
3811 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3813 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Changed the SILC packet header to have the first two bytes
3816 (the packet length) encrypted. Affected files aroung the
3817 code tree, lib/silccore/silcpacket.[ch]. Removed the
3818 SilcPacketCheckDecrypt callback. It is not needed anymore
3819 since the silc_packet_receive_process will determine now
3820 whether the packet is normal or special.
3822 * Implemented the unidirectional MAC keys. Affected files
3823 lib/silcske/silcske.c, silcd/protocol.c and
3824 lib/silcclient/protocol.c.
3826 * Implemented the packet sequence number to the MAC computation.
3827 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3828 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3829 lib/silcclient/protocol.c.
3831 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Allow backup router to announce servers. All servers
3834 announced by backup router are added to the global list
3835 automatically. Update hte server's socket to our primary
3836 router also when backup router announces a server.
3837 Affected file silcd/packet_receive.c.
3839 * Do not update the client->router in the function
3840 silc_server_udpate_clients_by_server if the client is on
3841 global list. We might fail to find any specific server
3842 for locally connected clients and local cell clients. They
3843 should still use the `from' and not `to' as client->router.
3844 This fixes backup router resuming protocol. Affected file
3845 silcd/server_util.c.
3847 * Decrease channel statistics count only if the channel
3848 deletion worked. Affected files are silcd/server.c and
3849 silcd/server_util.c.
3851 * Added silc_server_update_servers_by_server to update origin
3852 of all server entries. Used during backup router protocol.
3853 Affected files silcd/server_util.[ch], silcd/server.c. and
3854 silcd/backup_router.c.
3856 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3857 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3858 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3859 lib/silccrypt/silchmac.c.
3861 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Assure that router cannot reroute the same channel message
3864 to the sender. Affected file silcd/packet_receive.c.
3866 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Made better checks that the channel message is not sent
3869 to the router it came from. Affected file is
3870 silcd/packet_send.c. Fixed memory leak too.
3872 * Announce informations for incoming router connection, but
3873 only after checking if it is replaced by backup router.
3874 Affected file silcd/packet_receive.c.
3876 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3878 * Fixed the backup resuming protocol to work in multiple
3879 router environment. Affected file silcd/server_backup.c.
3881 * Route packet only to one router in the function
3882 silc_server_packet_send_to_channel. Affected file is
3883 silcd/packet_send.c.
3885 * Fixed silc_server_send_notify_dest to set the broadcast
3886 flag. Fixed the silc_server_send_notify_topic to actually
3887 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3888 Affected file silcd/packet_send.c.
3890 * Changed the SFTP Filesystem interface. Changed the
3891 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3892 the filesystem operation function. The SilcSFTPFilesystem
3893 is now a context that is allocated by all filesystem allocation
3894 functions and it already includes the operations structure
3895 and filesystem specific context. It is given as argument
3896 now to the silc_sftp_server_start. This made the interface
3897 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3898 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3900 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3902 * Changed the backup router adding and getting interfaces
3903 in the server. The router that will be replaced by the
3904 specified backup router is now sent as argument. Affected
3905 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3908 * Added silc_net_addr2bin_ne to return the binary form of
3909 the IP address in network byte order. Affected files
3910 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3912 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Check for existing server ID in silc_server_new_server
3915 and in silc_server_connect_to_router_final and remove the
3916 old entry if it exists. Affected file silcd/packet_receive.c,
3919 * Send the channel message always to only one router, either
3920 in upstream or downstream. Affected file is
3921 silcd/packet_send.c.
3923 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Wrote the definition of the backup resuming protocol to the
3926 protocol specification.
3928 * Removed one redundant channel key generation from normal
3929 server during joining procedure. Removed one redundant
3930 channel key sending from server to router during joining
3931 procedure. Affected file silcd/command.c.
3933 * Made minor bugfixes to the backup router resuming protocol.
3934 Affected file silcd/server_backup.c, server.c.

3943 resume the primary router position in the cell after the
3944 primary router comes back online. Affected files
3945 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3946 and silcd/server_util.[ch].
3948 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Sleep two (2) seconds after sending QUIT command to server.
3951 Affected file lib/silcclient/command.c.
3953 * Assure that if outgoing data buffer is pending do not force
3954 send any data. Affected file silcd/packet_send.c.
3956 * Assure that if outgoing data buffer is pending do not force
3957 send any data. Affected file lib/silcclient/client.c.
3959 * Implemented the backup router support when the primary router
3960 goes down. The servers and routers can now use the backup
3961 router as new primary router without loosing connectivity.
3963 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3965 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3966 in the server to indicate disabled entry. All data read
3967 from the connection will be ignored and no data is sent
3968 for entry that is disabled. Affected files are
3969 silcd/idlist.h, silcd/server.c.
3971 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Created SFTP client and server test programs in the
3974 lib/silcsftp/tests directory.
3976 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3978 * Implemented memory filesystem (virtual filesystem) for
3979 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3982 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * Implemented the SFTP (SSH File Transfer Protocol) to the
3985 lib/silcsftp. It includes SFTP client and SFTP server
3988 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * Moved lib/silccore/silcprotocol.[ch] to the
3991 lib/silcutil library.
3993 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3994 take variable argument list pointer as argument. Affected
3995 file lib/silcutil/silcbuffmt.[ch].
3997 * Added silc_buffer_set function that is used to set data
3998 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3999 Affected file lib/silcutil/silcbuffer.h.
4001 * Changed various routines in the core library to use the new
4002 silc_buffer_set instead of allocating new buffer only for
4005 * Added 64-bit value formatting and unformatting support to the
4006 silc_buffer_[un]format routines. Affected file is
4007 lib/silcutil/silcbuffmt.[ch].
4009 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4010 to includes/bitmove.h.
4012 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Fixed channel user mode saving in client library. Affected
4015 file lib/silcclient/command[_reply].c.
4017 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Defined the file transfer to the SILC Protocol. Added
4020 new packet type SILC_PACKET_FTP and defined File Transfer
4021 Payload. The mandatory file transfer protocol is SFTP
4022 (SSH File Transfer Protocol). Affected file in addition
4023 of the internet draft is lib/silccore/silcpacket.h.
4025 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4026 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4027 is used as part of backup router protocol when the primary
4028 router of the cell is back online and wishes to resume
4029 the position as primary router.
4031 * Redefined the MAC generation keys in the protocol. The
4032 same key is not used anymore in both direction. Both
4033 direction will now use different keys for sending and
4034 receiving. This fixes a potential security flaw. This
4035 change causes incompatibilities in the protocol.
4037 * Redefined also the MAC computation from the packet.
4038 An packet sequence number is now added to the MAC
4039 computation. This prevents possible replay attacks against
4040 the protocol. This change too causes incompatibilities
4043 Added `sequence' field to the SilcPacketContext to hold
4044 the current sequence number for the packet.
4046 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * Added `created' field to the SilcIDListData in the file
4049 silcd/idlist.h to indicate the time when the entry was
4052 * Added `created' field to the SilcChannelEntry too. Affected
4053 file silcd/idlist.h.
4055 * Added `creation_time' aguments to all the announcement functions
4056 in the server. If it is provided then only the entries that
4057 was created after the provided time frame are actually
4058 announced. Affected file silcd/server.[ch].
4060 * The protocol says that the Channel ID's IP address must be
4061 based on the router's IP address. Added check for this in
4062 the silc_server_new_channel when processing incoming New Channel
4063 Payload. Affected file silcd/packet_receive.c.
4065 * Print out the correct version with --version in SILC client.
4066 Affected file irssi/src/silc/core/silc-core.c.
4068 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Fixed WHOWAS command to check for completnes of the client
4071 entry always, not just when the command is coming from client.
4072 Affected file silcd/command.c.
4074 * Added new function silc_server_packet_queue_purge to purge the
4075 outgoing data queue to the network. After the function returns
4076 it is guaranteed that the outgoing packet queue is empty.
4077 Affected file silcd/packet_send.[ch].
4079 * Purge the outgoing packet queue in the rekey protocol's final
4080 callback to assure that all rekey packets go to the network
4081 before quitting the protocol. Affected file silcd/server.c.
4083 * Added silc_client_packet_queue_parse as similar function as
4084 in server to the client library. The affected file is
4085 lib/silcclient/client.c.
4087 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4089 * Splitted silcd/server.c and created silcd/server_util.[ch]
4090 for utility functions.
4092 * Added new socket flag SILC_SF_DISABLED to indicate that the
4093 connection is open but nothing can be sent to or received from
4094 the connection. Affected file lib/silcutil/silsockconn.[ch].
4095 The checking for disabled socket is checked in the low level
4096 silc_socket_write and silc_socket_read functions.
4098 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4100 * Allow only nicknames and channel names that fits into the
4101 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4103 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4105 * When processing JOIN command reply in server check that if
4106 the channel exists in our global list we'll move it the local
4107 list. Affected file silcd/command_reply.c.
4109 * Fixed the check whether client is joined on the channel already
4110 in JOIN command. Affected file lib/silcclient/command.c.
4112 * Fixed the JOIN command reply to check whether the channel
4113 already exists. Affected file lib/silcclient/command_reply.c.
4115 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Added silc_ske_status_string to map the SKE error numbers
4118 to readable strings. The affected files are
4119 lib/silcske/silcske[_status].[ch].
4121 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4123 * Do not show the private channels on the WHOIS channel list
4124 as it is not allowed by the protocol. The affected file is
4127 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4129 * Assure that the packet length digged from the actual packet
4130 is something sensible in the silc_packet_decrypt_rest_special
4131 in lib/silccrypt/silcpacket.c.
4133 * Free and NULL the allocated pointer in silc_hmac_alloc if
4134 the HMAC allocation fails. The affected file is
4135 lib/silccrypt/silchmac.c.
4137 * Print the selected security properties to the log files in
4138 the server. Affected file silcd/protocol.c.
4140 * Add SKE's reference counter even if calling the completion
4141 callback manually. Otherwise it goes negative, although it
4142 does not cause any problems. The affected file is
4143 lib/silcske/silcske.c.
4145 * Remove the client entry with short timeout after giving the
4146 KILL command. Affected file lib/silcclient/command.c.
4148 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4149 case all found clients are already disconnected (WHOWAS would
4150 found them) in the server. Affected file silcd/command.c.
4152 * Update the last_receive (time of last data received) to be
4153 updated only when received private or channel message so that
4154 the idle time showed in WHOIS makes more sense.
4156 * Added boolean field `valid' in to the SilcClientEntry in the
4157 client library to indicate whether the entry is valid or not.
4158 This fixes the nickname change bug on channel when changing
4159 the nickname to be same than the old (like nick to Nick) the
4160 nickname formatter doesn't set the new nick anymore to Nick@host.
4161 Affected file lib/silcclient/idlist.[ch].
4163 * Now actually fixed the nickname changing on disconnection.
4164 Added new function silc_change_nick to the Irssi SILC Client.
4165 Affected file irssi/src/silc/core/client_ops.c,
4166 irssi/src/silc/core/silc-nicklist.[ch].
4168 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Check that the public key exists in the GETKEY command before
4171 trying to encode it. Affected file silcd/command.c.
4173 * Print some notifications on received public keys with GETKEY
4174 command in the Irssi SILC Client. Affected files are
4175 irssi/src/fe-common/silc/module-formats.[ch],
4176 irssi/src/silc/core/client_ops.c.
4178 * Use IDENTIFY command to resolve the server information in the
4179 GETKEY command instead of INFO command. Affected file
4180 lib/silcclient/command.c.
4182 * All command reply functions in the client library now calls
4183 the pending command reply callbacks even if an error has
4184 occurred. The server has done this a long time and now it was
4185 time to move the client library to this as well. Now all
4186 errors can be delivered back to the pending command reply
4187 callbacks if necessary. Affected files are
4188 lib/silcclient/command[_reply].[ch].
4190 * Change the nickname on disconnection back to the username
4191 because in reconnect the server will enforce it to it anyway.
4192 Affected file irssi/src/silc/core/silc-servers.c.
4194 * Fixed a config file parsing bug in the Irssi SILC client.
4195 Affected file irssi/src/silc/core/clientconfig.c.
4197 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4199 * When printing the channel mode on JOIN, verify that the
4200 channel key and channel's HMAC are valid. Affected file
4201 irssi/src/silc/core/client_ops.c.
4203 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4206 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4207 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4209 * Removed channel key rekey task deleting from the function
4210 silc_server_save_channel_key. Affected file silcd/server.c.
4211 Added explicit timeout task context instead that is used to
4212 delete the task if we are registering a new task before the
4213 new task has elapsed.
4215 * When channel key rekey occurs the client library now saves
4216 the old channel key for a short period of time (10 seconds) and
4217 is able to use it in case some is still sending channel
4218 messages encrypted with the old key after the rekey. Affected
4219 file lib/silcclient/[idlist.h|client_channel.c].
4221 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4223 * Added check to the silc_server_new_id_real to not accept
4224 new ID if it is the sender's own ID. Affected file is
4225 silcd/packet_receive.c.
4227 * Assure that we do not announce ourself or the one we've
4228 sending our announcements when we're router and are announcing
4229 servers to our primary router. Affected file silcd/server.c.
4231 * Fixed silc_server_command_identify_check_client to assemble
4232 correct WHOIS packet. It send corrupted WHOIS packet and
4233 caused problem with router to router connections. Affected
4234 file silcd/command.c.
4236 Fixed also silc_server_command_whois_check the same way
4237 as for the IDENTIFY command.
4239 * Added new SilcIDListStatus to the server in the SilcIDListData
4240 structure. The status now includes the current status of
4241 the entry (like registered, resolved etc.). Affected file
4242 silcd/idlist.[ch]. Defined a bunch of different status types
4243 as well. This replaced the old boolean registered field as well.
4245 Added resolve_cmd_ident field to the SilcClientEntry structure
4246 too so that if the entry is for example being resolved so
4247 another command may attach to the same pending command reply
4248 without requiring to resolve the same entry again. This concept
4249 should optimize the WHOIS and the IDENTIFY resolving under
4250 heavy load by taking away unnecessary resolving for entries
4251 that are being resolved already.
4253 Added support for adding multiple pending commands for one
4254 command idenfier. Affected file silcd/command[_reply].[ch].
4256 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4257 before deleting the data. Otherwise the hash table will have
4258 freed data in comparison functions. Affected file is
4259 silcd/command_reply.c.
4261 * Fixed silc_idlist_replace_client_id to add the new entry to
4262 the cache with NULL nickname. Otherwise there will be invalid
4263 memory as the nickname after the nickname is freed. Affected
4264 file silcd/packet_receive.c.
4266 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4267 saved into wrong slots because the previous number of entries
4268 was not taken into account. Affected file silcd/idlist.c.
4269 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4271 * If we are router and we receive JOIN notify to a channel that
4272 does not have any users then notified client is marked as the
4273 channel founder, as it is it. The affected file is
4274 silcd/packet_receive.c
4276 * Added to the extended hash table API's table_del_*ext functions
4277 the destructor as argument too, so that the caller can decide
4278 which destructor to use or whether to use destructor at all.
4279 Affected file lib/silcutil/silchashtable.[ch].
4281 * Fixed ID Cache purging. It actually deleted the entries from
4282 the hash table after the data was freed. The hash table ended
4283 up comparing freed memory. The affected file is
4284 lib/silccore/silcidcache.c.
4286 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4288 * Fixed Irssi SILC client's KILL command's HELP syntax.
4290 * The USERS command now resolves the detailed user information
4291 if the userinfo field is missing. Affected file is
4292 lib/silcclient/command_reply.c.
4294 * Do not print error in silc_file_read if the read file does
4295 not exist. Just silently return NULL. Affected file is
4296 lib/silcutil/silcutil.c.
4298 * Fixed the silc_log_output to not wine about NULL filename
4299 and to not create some bogus " " filename. Affected file is
4300 lib/silcutil/silclog.c.
4302 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4304 * Fixed various printing bugs on the user interface in the
4305 Irssi SILC Client. Minor changes that were forgotten from
4308 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4310 * Fixed the configure.in.pre and the compilation and distribution
4311 environment to support the new autoconf 2.52. That version is
4312 now required to compile the CVS trunk.
4314 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4316 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4317 to generally parse user@fqdn format strings. Affected file
4318 lib/silcutil/silcutil.c.
4320 * Added nickname_format and nickname_force_format fields to the
4321 SilcClientParams structure. The first one defines the format
4322 for the nicknames that the library will enforce if the receives
4323 multiple same nicknames. The second one is boolean value and
4324 can be used to force the library to always enforce the format
4325 to the nicknames regardles whether there are multiple nicknames
4326 or not. This configurable formatting was employed to flexibly
4327 support accessing multiple nicknames from the user interface.
4328 The userinterface can now set the nicknames to what ever format
4329 they prefer. Affected file lib/silcclient/silcapi.h.
4331 Added function silc_client_nickname_format to the file
4332 lib/silcclient/idlist.c. It performs the nickname formatting.
4334 Added new field `hostname´ to the SilcClientEntry context.
4335 It holds the hostname of the client. Affected file is
4336 lib/silcclient/idlist.h.
4338 * Irssi SILC Client sets the nicknames in nick@hostn format.
4339 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4340 irssi/src/silc/core/silc-core.c.
4342 The WHOIS printing now also shows both the real nickname and
4343 the formatted nickname so that user knows how to access the
4344 user if there are multiple same nicknames cached. Affected
4345 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4346 printing formatting too to take the hostname now as a separate
4347 argument. The Affected file is
4348 irssi/src/fe-common/silc/modules-formats.[ch].
4350 * Changed the silc_client_get_clients_local to accept the formatted
4351 nickname as argument. It accepts the real nickname too but the
4352 formatted nickname can be used to find the true entry from
4353 multiple entries. Affected file lib/silcclient/silcapi.h and
4354 lib/silcclient/idlist.c.
4356 * Added nickname_format_parse field to the SilcClientParams.
4357 It is a callback function provided by the application to parse
4358 the nickname out of the formatted nickname string. The library
4359 calls it to get the nickname from the formatted string. Since
4360 the application generally knows better the format of the nickname
4361 string it parses it instead of the library, even though library
4362 encodes the formatted string. If the callback function is not
4363 provided then the library will use the string as is. The
4364 affected file is lib/silcclient/silcapi.h.
4366 * All the nickname strings passed to the client library in
4367 commands are now expected to be formatted nickname strings.
4368 If the command does not support the formatted nickname string
4369 it will assume that the sent string is the actual nickname.
4370 Affected file lib/silcclient/command.c.
4372 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4374 * Added public key authentication support to OPER and SILCOPER
4375 commands in the client library. Affected file is
4376 lib/silcclient/command.c.
4378 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4380 * Changed the get_auth_methdod client operation to be asynchronous.
4381 It can be async if the application resolves the authentication
4382 method from the server during the negotiation. Added new
4383 SilcGetAuthMeth completion callback that the application will
4384 call after resolving the authentication method.
4386 Added function silc_client_request_authentication_method that
4387 the application can use to resolve the authentication method
4388 from the server. Added also SilcConnectionAuthRequest callback
4389 that the library will call after the server has replied. The
4390 application can call this function if it does not know the
4391 current authentication method.
4393 Affected files are lib/silcclient/client.c and
4394 lib/silcclient/silcapi.h.
4396 * The Irssi SILC client now automatically resolves the authentication
4397 method incase any configuration information is not present (and
4398 currently there never is). The affected file is
4399 irssi/src/silc/core/client_ops.c.
4401 * Fixed public key authentication from the client library.
4402 Affected file lib/silcclient/protocol.c. Changed also the
4403 protocol specification about the public key authentication in
4404 the connection authentication protocol. The actual data to be
4405 signed is now computed with a hash function before signing.
4407 * Fixed the public key authentication from the server as well.
4408 Affected file silcd/protocol.c.
4410 * Removed the mlock()'s from the memory allocation routines.
4411 Affected file lib/silcutil/silcmemory.c. The ./configure does
4412 not check anymore for the mlock(). Affected file is
4415 * Fixed USERS command in server to allow the execution of the
4416 command for private and secret channels if the client sending
4417 the command is on the channel. Affected file silcd/command.c.
4419 * Fixed silc_client_get_clients_local to return the clients
4420 count correctly. It could return wrong value. Affected file
4421 lib/silcclient/idlist.c.
4423 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4425 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4426 types. The assembler optimizations seemed not to like 64-bit
4427 data types. The assmebler optimizations thus are now enabled
4428 also for BSD systems as opposed to only enable them for Linux.
4430 * Do not check for threads at all on BSD systems. Affected
4431 file configure.in.pre.
4433 * Removed -n and -h options from the Irssi SILC Client since
4434 they are not used in silc.
4436 * Fixed the prime generation to assure that the first digit
4437 of the generated random number is not zero since our conversion
4438 routines does not like number strings that starts with zero
4439 digit. If zero digit is seen the random number is regenerated.
4440 This caused some corrupted RSA keys when the zero first digit
4441 was met. Affected file lib/silcmath/silcprimegen.c.
4443 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4445 * Fixed WIN32 configuration in the ./configure script.
4446 Fixed to include xti.h on environments that has it.
4447 Patches by Carsten Ilchmann and andrew.
4449 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4451 * Changed the silc_id_create_client_id to be collision
4452 resistant. It is now assured that there cannot be created
4453 two same client ID's. I suspect that some weird bugs in
4454 the server were actually caused by duplicate Client IDs.
4455 Affected file silcd/serverid.[ch]. A router receiving
4456 new ID now also assures and informs the sending server
4457 if the ID caused collision.
4459 * Changed the silc_id_create_channel_id to also assure that
4460 there are no collisions.
4462 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4464 * Statement about ignoring the Mutual Authentication flag when
4465 performing rekey with PFS was a bit misleading. It is ignored
4466 if it was set in the initial negotiation, it cannot be even
4467 set in the rekey. Fixed in the ke-auth draft. Started the
4468 new versions of the protocol drafts in the doc/.
4470 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4472 * Fixed a bug in silc_client_command_identify_save when saving
4473 new channel information. The channel name was no duplicated
4474 and caused crash on exit. Affected file is
4475 lib/silcclient/command_reply.c.
4477 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Fixed the getkey command handling in the server. Send just
4480 empty OK reply to the sender if the key could not be fetched
4481 (but everything else was ok, like the key just was not available).
4482 Changed the public key parameter to optional in the protocol
4483 specs so that empty OK reply can be sent. Affected file
4486 Added a message to Irssi SILC client to tell to user if the
4487 server did not return a public key.
4489 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4491 * Fixed a channel key regeneration bug. It registered new
4492 timeout tasks exponentially until all system resources were
4493 used. Affected file silcd/server.c.
4495 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4497 * Added the SILC Document generator to the scripts/silcdoc.
4498 It can be used to generate the Toolkit Reference Manual out
4499 of the source tree. Internally it will also use the RoboDoc
4500 generator now imported in util/robodoc.
4502 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4504 * Added couple of return's in rekey protocol if error orccurred
4505 during the protocol. The execution must be terminated.
4506 Affected file silcd/protocol.c. Also, terminate the protocol
4507 always with timeout.
4509 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4511 * The client's Client ID was created initally from the wrong
4512 nickname (it could have been in format nick@host) in the
4513 silc_server_new_client. Affected file silcd/packet_receive.c
4515 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4517 * Added some SILC_LOG_ERROR's to various error conditions
4518 if client could not be added to ID cache. Affected files
4519 silcd/packet_receive.c and silcd/server.c.
4521 * When client's sock->user_data is freed, NULL also the
4522 client->router and client->connection pointers. Added check
4523 for these pointers being NULL to various places around the
4524 code. Affected file silcd/server.c.
4526 * Added client->data.registered == TRUE checks to various
4527 places around the code to assure that unregistered client's
4528 are not handled when it is not allowed. Affected file
4531 * Added `bool registered' fields to all
4532 silc_idlist_[server|client]_get_* routines to indicate whether
4533 the fetched client needs to be registered or not. Affected
4534 file silcd/idlist.[ch].
4536 * Add your own entry as registered to the ID cache in the
4537 server. Affected file server.c.
4539 * Fixed a bug in silc_server_new_server. The SilcServer was
4540 set as the new server's context instead of SilcServerEntry.
4541 This naturally caused some weird bugs.
4543 * Added "updated" field the SilcChannelEntry which indicates
4544 the time since the channel entry was last accessed. This
4545 can be used to determine whether it is necessary to
4546 announce the channel after backup resuming protocol.
4547 Affected files silcd/idlist.[ch].
4549 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4551 * Do not delete the channel rekey task when adding it
4552 for in silc_server_create_channel_key.
4554 * Changed the silc_server_create_channel_key to return
4555 TRUE or FALSE to indicate the success of the channel key
4558 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4560 * Fixed MSVC++ project files and added missing files to
4561 Makefiles under win32/.
4563 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4565 * Do not add TCP_NODELAY flag if the operating system
4566 does not have it defined. Affected files are
4567 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4569 * Fixed buffer overflow from Irssi SILC Client. Affected
4570 file irssi/src/fe-common/core/themes.c.
4572 * Fixed double free in client library in the file
4573 lib/silcclient/client.c when disconnecting from server.
4575 * Applied double free patch from cras to Irssi SILC client.
4576 Affected files irssi/src/core/[modules/expandos].c
4578 * Fixed the disconnection handling to Irssi SILC Client.
4579 The application must call silc_client_close_connection
4580 in ops->connect client operation in case of failure of
4581 the connection. Affected file is
4582 irssi/src/silc/core/client_ops.c.
4584 * Do not set sock->protocol to NULL in the function
4585 silc_client_close_connection after executing the protocol's
4586 final callback since the sock might not be valid anymore.
4587 Affected file lib/silcclient/client.c.
4589 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4591 * Do not enable SILC_THREADS if the linking with libpthread
4592 did not happen. Affected file configure.in.pre.
4594 * Added notion to protocol specification that server must
4595 verify the sent authentication payload with CMODE when
4596 setting the channel founder key. Implemented it to the
4597 server. Affected file silcd/command.c.
4599 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4601 * Added _EXTRA_DIST SILC distribution variable to the
4602 distributions file. It is used to conditionally add extra
4603 files or directories to the specific distribution. Affected
4604 files ./prepare, Makefile.am.pre and distributions.
4606 Removed the `_' from the start of the distribution names.
4609 * Added README.WIN32 for instructions to compile the Toolkit
4612 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4614 * Fixed a double free in disconnection in the server. Affected
4615 file is silcd/server.c.
4617 * Fixed the lib/silcske/groups.c to work now also with GMP
4618 MP library. The string conversion did not work when using
4619 specific base and the base is indicated in the string as well.
4621 * Created win32/ directory which now includes MSVC++ specific
4622 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4623 It will appear only in the toolkit distribution
4625 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4627 * Changed the key material distribution function in case when
4628 the hash output is too short. The data is now concatenated
4629 a bit differently than it used to. Made the change to the
4630 SKE protocol specification.
4632 * Added better GMP detection to configure.in.pre. A patch
4635 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4637 * Fixed a minor bug in SKE that might cause some problem on
4638 some platforms. Affected file lib/silcske/silcske.c.
4640 * Added the cookie checking for initiator in the SKE. It checks
4641 that the responder returns the sent cookie unmodified. The
4642 affected file is lib/silcske/silcske.c. Added new SKE
4643 error type INVALID_COOKIE that can be sent during the
4644 negotiation. Fixed some memory leaks as well.
4646 * Added the "invalid cookie" error message to Irssi SILC client's
4649 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4651 * Added `task_max' field to the SilcClientParams to indicate
4652 the maximum tasks the scheduler can handle. If set to zero,
4653 default values are used. Affected file lib/silcclient/silcapi.h.
4655 * Fixed memory leaks in silc_client_close_connection. Affected
4656 file lib/silcclient/client.c.
4658 * Added silc_client_del_client_entry to client library to free
4659 all memory of given client entry. Affected file is
4660 lib/silcclient/idlist.[ch].
4662 * Added new functions silc_client_del_channel and
4663 silc_client_del_server to delete channel and server entries.
4664 Affected file lib/silcclient/[silcapi.h/idlist.c].
4666 * Removed silc_client_del_client_by_id from silcapi.h.
4668 * Fixed the INFO command to return the server's own info
4669 correctly when querying by Server ID. Affected file is
4672 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4674 * Removed the non-blocking settings in WIN32 code in the
4675 silc_sock_[read/write] and added SleepEx instead. Affected
4676 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4677 of input data is now checked with FIONREAD and ioctlsocket.
4679 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4681 * Call silc_schedule_task_del_by_context in the
4682 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4683 Affected file lib/silccore/silcprotocol.c.
4685 * Call silc_protocol_cancel for active protocols in the
4686 silc_server_close_connection if the funtion
4687 silc_server_free_sock_user_data has not been called.
4688 Affected file silcd/server.c.
4690 * Generic tasks cannot be deleted using the del_by_fd
4691 task deleting function since generic tasks does not match
4692 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4694 * Added a notion to SILCOPER help file that the SILCOPER works
4695 only on router server, not on normal server.
4697 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * Added for WIN32 support for the new scheduler as well.
4700 Affected file lib/silcutil/win32/silcwin32schedule.c.
4702 * Fixed the SHA1 implementation to work on various platforms.
4704 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4706 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4707 API. It is part of the scheduler now. Everything else is
4708 as previously but some functions has changed their names.
4709 Checkout the lib/silcutil/silcschedule.h for the interface.
4710 Updated all applications to use the new interface. Affected
4711 files are lib/silcutil/silcschedule.[ch].
4713 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4715 * Found a bug in the SKE implementation. The HASH value,
4716 specified by the protocol, was not computed correctly. The
4717 public key of the responder was not added to the computation
4718 even though it is mandatory. Affected file lib/silcske/silcske.c.
4719 This unfortunately causes incompatibilities with older
4720 clients and servers.
4722 * Added WIN32 specific network init and uninit functions:
4723 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4724 the Winsock2. Affected file lib/silcutil/silcnet.h and
4725 lib/silcutil/win32/silcwin32net.c.
4727 * Set the socket always to nonblocking mode on WIN32 after
4728 reading data or writing data. Affected file is
4729 lib/silcutil/win32/silcwin32sockconn.c.
4731 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4733 * Fixed various compilation problems under WIN32. Affected
4734 files lib/silcutil/win32/silcwin32thread.c and
4735 lib/silcutil/win32/silcwin32schedule.c.
4737 * Removed all _internal.h #includes from public header
4738 files. Internal headers must never be included from
4741 Removed also the lib/silcske/payload_internal.h file.
4743 * All include files that may be needed (public and some others
4744 included by the public headers) by application developers are
4745 now copied to the ./includes directory. It does not copy any
4746 internal headers. Affected file Makefile.defines.pre and all
4747 Makefile.am's under lib/ and subdirs.
4749 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4751 * Do not change the ~/.silc directory's permissions automatically.
4752 Affected file irssi/src/silc/core/clientutil.c.
4754 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4756 * Do not cancel the protocol in silc_server_close_connection
4757 it might cause recursion. Now cancelled in the function
4758 silc_server_free_sock_user_data. Affected file silcd/server.c.
4760 * Fixed the silc_server_remove_clients_by_server to regenerate
4761 the channel keys correctly finally. Added also new function
4762 silc_server_remove_clients_channels to actually do it.
4763 Affected file silcd/server.c.
4765 * Fixed the silc_server_new_channel to not crash by giving
4766 wrong router to the new channel. Affected file is
4767 silcd/packet_receive.c.
4769 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4771 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4772 which is given as argument to the silc_client_alloc now.
4773 It can be used to configure the client and set various parameters
4774 that affect the function of the client.
4776 * The USERS command in server did not check whether the channel
4777 is private or secret. Affected file silcd/command.c.
4779 * Added new argument to the USERS command in protocol specification.
4780 The USERS command now can take the channel name as argument
4781 as well. Added support for this in client and server and
4782 updated the protocol specs.
4784 * Completed the GETKEY command in client. It can be now used
4785 to fetch also servers public key not only some clients.
4786 Affected files lib/silcclient/command[_reply].c.
4788 * Added silc_client_get_server to return server entry by the
4789 server name. Affected files lib/silcclient/silcapi.h and
4792 * Redefined the IDENTIFY command in protocol specification to be
4793 more generic. It now can be used to query information about
4794 any entity in the SILC Network, including clients, servers and
4795 channels. The query may be based either the entity's name
4796 or the ID. Added support for this in both client and server.
4798 Affected files silcd/command.c and lib/silcclient/command.c
4799 and command_reply.c.
4801 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4802 the _from_client and _from_server functions. Affected file
4805 * Added silc_client_get_channel_by_id_resolve to the file
4806 lib/silcclient/silcapi.h to resolve channel information by
4807 its ID. Added also silc_client_get_channel_by_id that
4808 does not resolve it from the server.
4810 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4812 * Added SilcServerEntry context into the client library
4813 to represent one server. The INFO command now allocates
4814 these to save the resolved server info. For now on the
4815 client library will also keep information about servers,
4816 connected and resolved with INFO.
4818 The INFO command now allocates the SilcServerEntry context
4819 and saves the server info there. The COMMAND_REPLY in
4820 the INFO now returns the parameters to application in
4821 same order as defined in the protocol specification.
4823 The entries are cached in the client->server_cache.
4825 * The INFO command is now issued after received the Client ID
4826 from the server. Affected file lib/silcclient/client.c.
4828 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4829 to the application as the mode changer might be server.
4830 It is guaranteed that NULL is not returned anymore to the
4831 application. Affected file lib/silcclient/client_notify.c.
4833 The ID Type is now also passed to the application so that
4834 it can check whether the returned entry is SilcClientEntry
4837 Added new function silc_client_get_server_by_id to return
4838 the server entry by ID. Affected files are the
4839 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4841 * Do not create the channel in the Irssi SILC Client when issuing
4842 the JOIN command but when received the sucessful JOIN command
4843 reply. Otherwise the channel might get created even though we
4844 could not join it. The Affected file is
4845 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4847 * Fixed a channel joining bug in router. The router must also
4848 check the channel modes, invite and ban lists etc. when serving
4849 the JOIN command sent by normal server. Affected file is
4850 silcd/command.c. The router now resolves the client's
4851 information from the server who sent the JOIN command if it
4852 does not know it, and processes the JOIN command only after
4855 * Changed the SilcCommandCb to take new argument; void *context2.
4856 Affected file lib/silccore/silccommand.h
4858 The second argument in the command callbacks in the server now
4859 includes the SilcServerCommandReplyContext if the command was
4860 called as pending command callback from the command reply.
4861 Otherwise it is NULL. When called as pending the status of the
4862 command reply will be checked and if it was erronous the
4863 error will be sent to the original sender of the command.
4864 This way the client always receives the error messages even
4865 though the server was actually the one who received the error
4866 when it resent the command to router, for example. Affected
4867 files silcd/command[_reply].[ch].
4869 * Fixed sending WHOWAS command's error message to client if
4870 the requested client could not be found. It was missing.
4873 * Changed the CMODE and CUMODE commands reply arguments in the
4874 protocol specification. The Channel ID is now sent in both
4875 of the commands to identify the channel. Implemented this
4876 new feature to the client and server. Affected files
4877 lib/silcclient/command_reply.c and silcd/command.c.
4879 * Made better checks for invite and ban lists in the JOIN
4880 command in server. Affected file silcd/command.c.
4882 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4884 * The server now performs the incoming host IP/DNS lookup
4885 using the silc_socket_host_lookup and thus does not block
4886 the server anymore. Affected file silcd/server.c.
4888 * Completed the multi-thread support for SILC Scheduler in
4889 the lib/silcutil/silcschedule.c.
4891 * Fixed the configure.in.pre to detect the pthread correctly
4894 * Fixed a deadlock in silc_task_queue_wakeup in the file
4895 lib/silcutil/silctask.c.
4897 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4899 * Added new function silc_schedule_wakeup that is used in
4900 multi-threaded environment to wakeup the main thread's
4901 schduler. It needs to be used when a thread adds a new task
4902 or removes a task from task queues. After waking up, the
4903 scheduler will detect the task queue changes. If threads
4904 support is not compiled in this function has no effect.
4905 Implemented the wakeup mechanism to both Unix and WIN32
4906 systems. Affected files are lib/silcutil/silcschedule.[ch],
4907 lib/silcutil/unix/silcunixschedule.c and the
4908 lib/silcutil/win32/silcwin32schedule.c.
4910 * Added new function silc_task_queue_wakeup to wakeup the
4911 scheduler by the specified task queue. Affected file
4912 lib/silcutil/silctask.[ch].
4914 * The silc_socket_host_lookup_start now wakes up the scheduler
4915 after adding the timeout task. Affected file is
4916 lib/silcutil/silcsockconn.c.
4918 * The silc_socket_host_lookup is synchronous now if the threads
4919 support is not compiled in. However, the callback is still
4920 called asyncronously through the scheduler, anyway. Affected
4921 file lib/silcutil/silcsockconn.c.
4923 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4925 * Added new function silc_socket_host_lookup to perform
4926 asynchronous IP and FQDN lookups for the socket connection.
4927 Affected files lib/silcutil/silcsockconn.[ch].
4929 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4931 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4932 that may or may not compile the mutex support in.
4934 Changed the silc_mutex_alloc interface. It allocates the
4935 mutex now to the sent pointer and returns TRUE or FALSE.
4937 Affected file lib/silcutil/silcmutex.h.
4939 * Wrote the SILC Task Queue interface to support multi-threads.
4940 Affected file lib/silcutil/silctask.[ch].
4942 * Wrote the SILC Scheduler to support multi-threads. Affected
4943 file lib/silcutil/silcschedule.c.
4945 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4947 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4948 in lib/silcutil/win32/.
4950 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4952 * Defined SILC Mutex API and SILC Thread API and implemented
4953 them for Unix. Affected files are
4954 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4955 lib/silcutil/unix/silcunixmutex.c and
4956 lib/silcutil/unix/silcunixthread.c.
4958 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4960 * Fixed the silc_server_remove_clients_by_server's channel
4961 key re-generation. The hash table handling was incorrect
4962 and would not work with many channels. Affected file is
4965 * Fixed some memory leaks around the server code.
4967 * Rewrote the silc_server_get_users_on_channel to support IPv6
4968 based Client ID's. Affected file silcd/server.c.
4970 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4971 specification. However, a separate document must be written
4972 to define the detailed signing procedure and the payload
4973 associated with the flag. Defined the flag to the
4974 lib/silccore/silcchannel.h as well.
4976 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4978 * Changed the dynamic tables to static size tables in the
4979 lib/silccrypt/silchmac.c.
4981 * Removed GCC dependencies from the code. A patch by cras.
4983 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4985 * Do not show the error "Error receiving packet bla bla"
4986 in server if it really was not an error (-2 means that reading
4987 is pending). Affected file silcd/server.c.
4989 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4991 * Fixed a possible crash in silc_server_remove_clients_by_server
4992 in silcd/server.c. Fixed there also some memory leaks.
4994 * Fixed the silc_idlist_replace_client_id. It could replace
4995 wrong key in the hash table. Affected file silcd/idlist.c.
4997 * Do not check whether there are global users on the channel
4998 if the channel->global_users is FALSE. Affected functions
4999 silc_server_remove_from_one_channel and
5000 silc_server_remove_from_channels in silcd/server.c. Also,
5001 do not check if the removed client is local as we can be
5002 sure that global client was not removed from the channel
5003 and checking for global users is not needed.
5005 * The silc_server_remove_clients_by_server now re-generates
5006 the channel keys correctly for those channels that had
5007 clients removed from them. Affected file silcd/server.c.
5009 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5011 * Found the reason of random crashes in the server. We weren't
5012 ignoring the SIGPIPE signal (which can be sent in write())
5013 and it crashed the server. Affected file silcd/silcd.c.
5015 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5017 * Assure that sock->user_data is not NULL in the function
5018 silc_server_packet_send in silcd/packet_send.c.
5020 * Disconnect the remote connection if it could not be added
5021 to any ID lists in the server. The affected file is
5024 * Check in silc_server_packet_send[_real/dest] that the
5025 socket is not disconnecting and ignore the data if it is.
5026 Affected file silcd/packet_send.c.
5028 * Define inline to __inline on native WIN32 compilation.
5029 Affected file includes/silcwin32.h.
5031 * Added some explicit type casts for inline code since MSVC
5032 require them. Affected files lib/silcutil/silcbuffer.h,
5033 lib/trq/silcdlist.h and lib/trq/silclist.h.
5035 * Print warning in log files from now on if the packet
5036 decryption fails. Affected file silcd/server.c.
5038 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5040 * Changed the `say' client operation's interface to accept
5041 new `type' argument to indicate the type of the message sent
5042 by the library. The application may filter the library's
5043 messages according the type. The affected file is the
5044 lib/silcclient/silcapi.h.
5046 * Added two new functions to lib/silcclient/silcapi.h:
5047 silc_client_del_client and silc_client_del_client_by_id.
5048 Affected file lib/silcclient/idlist.c.
5050 * Moved the clientincludes.h from includes/ to silc/ and
5051 serverincludes.h from includes/ to silcd/.
5053 * The modes for the CMODE and CUMODE are now passed as
5054 uint32 for application with COMMAND_REPLY. The affected
5055 file is lib/silcclient/command_reply.c.
5057 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5059 * /WHOIS without arguments shows client's own information.
5060 Affected file lib/silcclient/command.c.
5062 * Changed PING to not accept any arguments. The specs
5063 says that client can ping only the connected server so
5064 requiring an argument is not needed. Affected file is
5065 lib/silcclient/command.c.
5067 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5069 * Fixed a fatal bug in private message sending and reception
5070 encryption and decryption when using private message keys.
5071 The implementation was incorrect and did not follow the
5072 specification. It causd that some of the message were
5073 lost since it did not use the sending and receiving keys
5074 as the protocol suggests. This has been fixed and will cause
5075 incompatibilities with older clients when sending private
5076 message encrypted with private message keys. Affected files
5077 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5078 and various other in Irssi SILC Client.
5080 Added `responder' boolean argument to the functions
5081 silc_client_add_private_message_key[_ske] to indicate when
5082 the key is added as responder or initiator of the key
5085 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5087 * Removed the silc_ske_check_version function and created
5088 a SilcSKECheckVersion callback. Added also a function
5089 silc_ske_set_callbacks that is now used to set all SKE
5090 callbacks. The callback functions are not given to
5091 the SKE functions anymore, but this function is used to
5094 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5096 * Added `silc_version' argument to the silc_client_alloc
5097 to define the version of the application for the library.
5098 The library will use the version string to compare it
5099 against the remote host's (usually a server) version
5100 string. Affected file lib/silcclient/silcapi.h
5102 * Added the KE protocol context to Key Agreement context
5103 in client library so that we can abort the SKE if it
5104 is in process when we get timeout. Affected file is
5105 lib/silcclient/client_keyagr.c.
5107 * Do not resolve the client ID forever if it returns in the
5108 first time that such client does not exist. This was done
5109 for example with private message. Affected file is
5110 lib/silcclient/client_prvmsg.c.
5112 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5114 * Do not add regex.h for WIN32. The affected file
5115 includes/silcincludes.h.
5117 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5118 not work yet 100%. It generates the DLL's automatically
5119 when compiling with --with-win32 under cygwin.
5121 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5123 * lib/contrib/regex.c is not compiled on WIN32.
5125 * Added silc_net_get_socket_opt function to the
5126 lib/silcutil/silcnet.h.
5128 * Added includes/silcwin32.h for WIN32 specific includes
5131 * Do not use ptime structure or any of the posix process
5132 functions on WIN32 in lib/silccrypt/silrng.c.
5134 * Added silc_gettimeofday to provide generic function
5135 for struct timeval on all platforms. Added the function
5136 to lib/silcutil/silcutil.h.
5138 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5140 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5141 library as they clearly belong there. As a plus side we
5142 can make the actual socket connection routines platform
5145 Added also new generic function silc_socket_read and
5146 silc_socket_write (that used to be silc_packet_[read/write].
5147 The implementation of these are platform specific.
5149 * Added WIN32 specific routines of silc_socket_[read/write]
5150 to lib/silcutil/win32/silcwin32sockconn.c.
5152 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5154 * Added preliminary support for native WIN32 compilation under
5155 cygwin (using the -mno-cygwin option for GCC) to the
5156 ./configure.in.pre. The --with-win32 now prepares the
5157 compilation for native WIN32.
5159 * Rewrote the SILC Scheduler interface in the file
5160 lib/silcutil/silcschedule.h. The scheduler is now context
5161 based and does not have anymore any global static scheduler.
5162 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5163 and created lib/silcutil/win32 directory for WIN32 based
5166 * Added Unix specific network routines to the
5167 lib/silcutil/unix/silcunixnet.c and the old
5168 lib/silcutil/silcnet.c includes now only generic routines.
5170 Added WIN32 specific network routines to the
5171 lib/silcutil/win32/silcwin32net.c.
5173 * Added Unix specific utility functions from the
5174 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5176 * Added WIN32 SILC Scheduler to the file
5177 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5180 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5182 * Do not handle JOIN notify in the server if the target client
5183 is not registered (idata->registered == FALSE). The affected
5184 file is silcd/packet_receive.c.
5186 * Update the nickrec->founder in event_cumode in the Irssi SILC
5187 client. Affected file irssi/src/silc/core/silc-channels.c.
5189 * Fixed the CUMODE_CHANGE notify handling in the server when
5190 server and router are announcing their clients on channels.
5191 Now the mode changes are saved and notified correctly. The
5192 affected file is /silcd/packet_receive.c.
5194 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5195 They really did not replace the cache entry in the ID Cache.
5196 Now they do that. Affected file silcd/idlist.c.
5198 * Fixed the KICK notify handling in the Irssi SILC client to
5199 update the channel records so that the kicked client does not
5200 appear to be on the channel. The affected file is
5201 irssi/src/silc/core/silc-channels.c.
5203 * Always update the conn->current_channel when executing command
5204 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5206 * Fixed the KILL notify handling in Irssi SILC client to remove
5207 the killed client on all channels.
5209 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Fixed the silc_parse_command_line to remove extra spaces
5212 from the start and end of the arguments. Affected file is
5213 lib/silcutil/silcutil.c.
5215 * Cancel and free any active protocol in the function
5216 silc_server_close_connection. Affected file silcd/server.c.
5218 * Cancel and free any active protocol in the function
5219 silc_client_close_connction. Affected file is
5220 lib/silcclient/client.c.
5222 * Do not execute the KILL command for clients that are in
5223 history (ie. they are not in the network). Affected file is
5226 * Fixed KILL notify handling, client does not crash anymore.
5227 Affected file irssi/src/silc/core/silc-channels.c.
5229 * Reduced the default packet buffer size from 2048 to 1024 in
5230 lib/silccore/silcpacket.c.
5232 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5233 counter to the SKE context that is incresed when the SKE library
5234 performs async operation outside the library. If the outside
5235 process frees the SKE context and FREED status will be set
5236 and the library will detect after the sync operation that the
5237 libary is freed. The affected files are
5238 lib/silcske/silcske[_status].[ch].
5240 * Resolve the client entry information in the function
5241 silc_client_channel_message to assure that NULL pointer is not
5242 passed as client entry to the application. */
5244 * Fixed the task timeout calculation to assure that there is
5245 never negative timeouts. The affected file is
5246 lib/silcutil/silcschedule.c.
5248 * Fixed the channel user mode notification sending in server.
5249 It was sent point-to-point to the router (or to server by router)
5250 but it needs to be destined to a channel. The routines now
5251 supports sending the channel user mode notifys to the channels
5252 when announcing clients and channels. Affected files are
5253 silcd/server.c and silcd/packet_receive.c.
5255 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5256 It did not actually replace the old channel entry in the cache.
5257 Affected file lib/silcclient/client_notify.c.
5259 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Fixed a possible crash in silc_packet_send_prepare. It now
5262 assures always that there is enough space in the buffer and
5263 at the tail area of the buffer (for MAC).
5265 Fixed the inbound buffer reallocation in silc_packet_read.
5266 It was old code and did not handle the reallocation correctly.
5269 The affected file is lib/silccore/silcpacket.c.
5271 * Fixed buffer overflow in silc_parse_nickname in the file
5272 lib/silcutil/silcutil.c.
5274 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * make install generates new server keys only if there is not
5279 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5282 Added check that if the NOREPLY is set then we will not send
5283 the away message. This avoids infinite loop of away messages
5284 if both clients are away. The affected file is
5285 lib/silcclient/client_prvmsg.c.
5287 * Fixed client crash if /NICK was given without arguments.
5288 Affected file lib/silcclient/command.c.
5290 * Server does not send the invite list in INVITE command back
5291 to the client if the list was not altered. Added this notion
5292 to the protocol spec as well. Affected file silcd/command.c.
5294 Fixed possible crash in INVITE command by checking the
5295 value of silc_server_get_client_route command.
5297 * Fixed the INVITE notify type handling. The arguments are now
5298 taken in correct order and client does not crash. The affected
5299 file is irssi/src/silc/core/silc-channels.c.
5301 Removed the "Inviting xxx to channel" message from the
5302 client library away and let the application handle it.
5303 Affected file lib/silcclient/command.c. Added that message
5304 to Irssi SILC client's message formats.
5306 * Fixed CMODE command crash in client. It now checks the
5307 amount of arguments correctly and does not crash. The affected
5308 file is lib/silcclient/command.c.
5310 * Do not create new channel automatically in silc_channels_join
5311 but check whether the channel by that name already exists.
5312 Affected file irssi/silc/core/silc-channels.c.
5314 * Do not send the SERVER_SIGNOFF to router if the disconnected
5315 entity was the router. Affected file silcd/server.c.
5317 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5318 SILC client as it was missing from there.
5320 Added the handling of the KICK notify to the Irssi SILC client
5321 as it was missing. Added "you have been kicked" message to
5322 Irssi SILC client's message modules formats.
5324 Added the handing of the KILL notify to the Irssi SILC client
5325 as it was missing. Added the kill message module formats
5328 The affected file is irssi/src/silc/core/silc-channels.c.
5330 * The router did not save the channel mode the server announced.
5331 Affected file silcd/packet_receive.c.
5333 * Fixed a possible crash in INFO command in server. If the
5334 server did not provide the server info it crashed. Affected
5335 file silcd/command.c.
5337 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Fixed the GETKEY command in the server to check also the
5340 global list. Otherwise the GETKEY would not work correctly
5341 in normal SILC server. Affected file silcd/command.c.
5343 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Fixed GETKEY crash, it crashed if the command did not succseed.
5347 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5350 is now real and not just an macro interface to GMP.
5352 Removed the entire GMP from the source tree and imported new
5353 NSS MPI library instead. Reason for removing GMP is that it is
5354 extremely large and compiles extremely slow. The NSS MPI
5355 is only a few files and compiles in less than 10 seconds.
5356 The speed is also about the same as GMP. The MPI is imported
5357 to lib/silcmath/mpi.
5359 If the system has GMP installed we will still use the GMP.
5360 If it is not then the NSS MPI will be compiled.
5362 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Merged a long nickname (127 characters long) crash bugfix from
5365 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5367 * Merged a freed memory reference bugfix from Irssi CVS tree.
5368 Affected file irssi/src/core/commands.c.
5370 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Added the server's public key sving and verification to the
5373 server when performing the SKE. This was missing and the
5374 remote server's (or router's) public key was accepted without
5375 checking whether we have it previously or trust it at all.
5376 Affected file silcd/protocol.c.
5378 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Check in the silc_server_timeout_remote if protocol is active
5381 and make sure that the protocol's final callback is called so
5382 that all memory if freed. Affected file silcd/server.c.
5384 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * silc_server_whois_send_reply crashed the server if the nickname
5387 was 127 characters long. Affected file silcd/command.c.
5389 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added sanity check to the silc_server_new_client. If the hostname
5392 is provided inside username then check that the provided hostname
5393 really is the same as the resolved one. If the hostname was not
5394 resolved then check it from the public key. Affected file is
5395 silcd/packet_receive.c.
5397 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5398 if the server disconnected us and the connection is not valid
5399 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5401 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5402 the library to the lib/silcutil/silcutil.[ch].
5404 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Close log file after open. Affected file
5407 lib/silcutil/silclog.c.
5409 * Check whether sock == NULL in silc_client_send_packet and return
5410 if it is. Affected file lib/silcclient/silcclient.c.
5412 * Check rec->entry == NULL in the Irssi SILC Client before
5413 sending the channel message. Affecte file is
5414 irssi/src/silc/core/silc-servers.c.
5416 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Merged a splitted window bugfix from Irssi CVS tree. The
5419 affected file is irssi/src/fe-text/textbuffer-view.c.
5421 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5422 It did not print nickname.
5424 * Improved the distributions system a bit.
5426 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5429 irssi/src/fe-text/gui-window.c.
5431 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5432 to in-active server. The affected file is
5433 irssi/src/silc/core/client_ops.c.
5435 * Resolve the client in USERS command reply if the entry does
5436 not have username resolved. The affected file is
5437 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5438 command to WHOIS command to really resolve stuff. The USERS
5439 is not used any more in any critical section so WHOIS can
5440 be used even though it might be slower than IDENTIFY.
5442 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5445 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Changed the protocol API a bit more consistent in the
5448 lib/silccore/silcprotocol.[ch].
5450 * Changed the following headers to ROBODoc format:
5452 lib/silccore/silcpayload.h
5453 lib/silccore/silcprotocol.h
5454 lib/silccore/silcsockconn.h
5456 All core library headers are now formatted.
5458 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Fixed a bug in Irssi SILC client; do not show that you are
5461 server/router operator if you really are not. Affected file is
5462 irssi/src/silc/core/client_ops.c.
5464 * Renamed silc_command_free_payload to silc_command_payload_free.
5465 Affected file lib/silccore/silccommand.h
5467 * Added silcmath.h to include the prototoypes of various routines
5468 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5471 * Changed the following headers to ROBODoc format:
5473 lib/silccore/silcchannel.h
5474 lib/silccore/silccommand.h
5475 lib/silccore/silcid.h
5476 lib/silccore/silcidcache.h
5477 lib/silccore/silcmode.h
5478 lib/silccore/silcnotify.h
5479 lib/silccore/silcpacket.h
5480 lib/silcmath/silcmath.h
5482 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Added checking to the server code not to start the server if
5485 ciphers and stuff are not configured properly. Affected files
5486 silcd/serverconfig.[h] and silcd/server.c.
5488 * Changed the layout of the header files of the public interfaces
5489 in the SILC libraries. The new layout supports ROBODoc
5490 documentation tool (and some others) so that it is easy to create
5491 a library reference manual. All the other headers and source
5492 code must still follow the CodingStyle document. Also source
5493 code must not include these ROBODoc stuffs, only the headers.
5494 Furthermore, all public interface headers must now be named
5495 by using `silc' prefix, example: silcapi.h, silccipher.h.
5496 Some files were renamed due to this. All the other headers
5497 must not be used as public interfaces. I will update the
5498 CodingStyle document later. Changed following headers, so far:
5500 lib/silcclient/silcapi.h
5501 lib/silccore/silcauth.h
5502 lib/silccore/silcprivate.h
5503 lib/silccrypt/silcdh.h
5505 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Removed silc_client_packet_send_flush from the client library
5510 as it is not needed. Affected file lib/silcclient/client.[ch].
5512 * Added printing of message of unresolved authentication method
5513 to the Irssi SILC client. Added it to the module formats.
5514 Removed the same message from the client library.
5516 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added new distribution feature, DISTLABEL. Every distribution
5519 can define own preprocessor label that can be used in the
5520 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5521 file distributions, acconfig.h.pre and prepare.
5523 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added Makefile.defines_int to include the actual definitions
5526 for Makefile.defines.in. Tested the new distribution system,
5527 created distributions and tested installation.
5529 * Added AWAY message printing to the Irssi SILC client. Added
5530 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5532 * Added SCONNECT command to call the SILC's CONNECT command.
5533 Cannot use CONNECT directly since Irssi uses that internally.
5534 Affected file irssi/src/silc/core/silc-servers.c.
5536 Added ACTION local command. It is same as ME command but takes
5537 the channel as mandatory argument.
5539 Rewrote some of the Irssi's help files to suite for SILC
5542 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Added Makefile.defines[.in] that should for now on be included
5545 in all Makefile.am file in the source tree. That file includes
5546 all common compilation definitions for SILC source tree.
5548 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Minor changes to the ./prepare script to change the package
5551 name according the distribution name to the configure.in.
5553 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Created new distribution system. Added file `distributions'
5556 that defines all the distributions that can be created out of
5557 the SILC source tree. The ./prepare script now reads that
5558 file to determine how to prepare the distributions. The
5559 first argument to the ./prepare is the name of the distribution
5560 and second is the version of the distribution. If given
5561 without arguments it creates the default (toolkit) distribution
5562 with the default version (defined in ./prepare).
5564 All Makefile.am files that are subject to the distributions
5565 are now named as Makefile.am.pre. These are ./Makefile.am
5566 and lib/Makefile.am. Others may be changed later.
5568 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Added invite list, ban list, some key management and connection
5571 error message printing to module formats in the Irssi SILC client.
5573 * Added new silc_client_set_away_message to set the away message
5574 that is back to the person who sent private message. The
5575 affected file lib/silcclient/silcapi.h and the
5576 lib/silcclient/client_prvmsg.c.
5578 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Fixed the private message sending in the Irssi SILC client,
5581 added local command KEY to the Irssi SILC client.
5583 Added key management and key agreement message formats to the
5584 irssi/src/fe-common/silc/module-formats.[ch].
5586 Added USERS (alias WHO) printing, server/router operator
5587 indication and LIST command printing to the module formats.
5589 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Fixed channel joining notify handling, cumode notify handling
5592 from Irssi SILC client.
5594 * Added SILC specific module-formats to the Irssi SILC client so
5595 that SILC specific message hilighting, colors etc is possible.
5596 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5598 Added channel mode, channel user mode, actions, notices,
5599 whois and whowas printing to the the module-formats.c.
5601 * Fixed a bug in channel deletion in the server. The channel
5602 is not left to the cache even if the channel founder auth mode
5603 is set when there are no users anymore on the channel. Affected
5604 file silcd/server.c.
5606 * The silc_net_localhost now resolves the entire hostname including
5607 the domain name. Affected file lib/silcutil/silcnet.c.
5609 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Changed the ask_passphrase client operation to be ascynchronous.
5612 It has now a completion callback and a context that the
5613 application must call after it has got the passphrase from
5614 the user. Affected files lib/silcclient/silcapi.h,
5615 lib/silcclient/protocol.c, lib/silcclient/command.c and
5618 Added SilcAskPassphrase callback that the application calls
5619 to deliver the passphrase to the library.
5621 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5622 The public key verification and especially a certificate
5623 verification is asynchronous procedure.
5625 Added new SILC_SKE_STATUS_PENDING status to indicate the
5626 request is pending and a callback will be called to finalize
5629 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5630 indicate that remote end did not send its public key (or
5631 certificate), even though we require it. Added check for this
5632 condition in the SKE. This was a security bug, now fixed.
5634 Defined new SilcSKEVerifyCbCompletion callback that is called
5635 when the verification process is completed.
5637 The affected files lib/silcske/silcske_status.h and
5638 lib/silcske/silcske.[ch].
5640 * Changed the verify_public_key client operation to be async
5641 as well. Defined SilcVerifyPublicKey callback that is used to
5642 indicate the success of the public key verification process.
5644 Changed the server and client to use the new async client
5647 * Changed the Irssi SILC client's internal scheduler to be called
5648 twice as many times as it used to be. As a result the client
5649 should be a bit faster now. Affected file is
5650 irssi/src/silc/core/silc-core.c.
5652 * Added support to Irssi SILC client of asynchronous public key
5653 verification and passphrase inquiry. Affected file is
5654 irssi/src/silc/core/silc-core.c.
5656 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Do not say "You have left channel %s" in client library.
5659 Moved it to the application. Affected files are
5660 lib/silcclient/command.c and silc/client_ops.c.
5662 * Fixed silc_client_get_clients. Command context was not
5663 duplicated and was freed memory in the callback. Affected
5664 file lib/silcclient/idlist.c.
5666 * Do not say "you are now talking..." on JOIN command in the
5667 client library. The appliation must handle it.
5669 * Do not say ".. changed topic to" in command reply in the
5670 client libary. The application must handle it.
5672 * Fixed TOPIC command sending in the client library.
5674 * Fixed a memory leak in silc_client_command_free in the file
5675 lib/silcclient/command.c.
5677 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Imported a modified version of Irssi client to the source tree.
5680 The Irssi will be used to create a new client called
5681 Irssi SILC. Imported to irssi/.
5683 Added silc_core_init_finish function to the Irssi. Affected
5684 file irssi/configure.in.
5686 A lot changes in the Makefile.ams around the irssi tree.
5688 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Do not rehash if the new size is same as the old size of the
5691 hash table, in the silc_hash_table_rehash*. The affected file
5692 lib/silcutil/silchashtable.c.
5694 * Replaced hash_table_del_by_context calls from the server
5695 (when channel->user_list and client->channels) to the
5696 hash_table_del as it is sufficient and faster.
5698 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Added silc_hash_table_list, silc_hash_table_get and the
5701 SilcHashTableList structure to provide an alternative way to
5702 traverse the hash table. The affected files are
5703 lib/silcutil/silchashtable.[ch].
5705 * Changed the server's idlist routines to use the hash table
5706 routines to optimize the code.
5708 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Replaced the client entry's `channel' list and channel entry's
5711 `user_list' list to hash tables for optimized lookup. Changed
5712 the code to use the hash table interface around the code.
5713 Affected file lib/silcd/idlist.[ch].
5715 * Added `auto_rehash' boolean argument to the function
5716 silc_hash_table_alloc to indicate whether the hash table should
5717 auto-rehash when it thinks is appropriate time. It will
5718 increase the hash table size if the there is twice as much
5719 entries in the table than the size of the table, and will
5720 decrease the size if there are twice as less entries than
5721 the size of the table.
5723 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5727 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * silc_idcache_purge_by_context deletes the entry now by context
5730 as it is supposed to do. Affected file lib/silccore/idcache.c.
5732 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5733 client is not anymore valid (WHOWAS givens the info) and not
5734 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5736 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Removed the `data' and `data_len' arguments from the ID Cache
5739 interfaces and added `name' argument. ID Cache does not handle
5740 anymore the binary data only a names associated with given ID.
5742 * When hashing a Client ID with silc_hash_id the entire ID is
5743 not hashed anymore, instead only the hash of the Client ID is
5744 hashed. This way we can access the Client ID from the cache
5745 with Client ID but with the hash of the ID (which is a hash of
5746 the nickname) as well without any difference in performance.
5748 Added also silc_idcache_find_by_id_one_ext to do one on one
5749 searching when we have the actual ID. Added also function
5750 silc_hash_client_id_compare. The affected files are
5751 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5753 * When hashing the name associated with a ID it is always done
5754 in lowercase. This way we can access the cache without worrying
5755 about case-sensitivity, even though, for example nicknames are
5758 * Fixed a bug in server with channel message sending. It put
5759 wrong ID type as destination ID. The affected file
5760 silcd/packet_send.c.
5762 * silc_idcache_del_by_context now deletes from all hash tables
5763 by context. Affected file lib/silccore/idcache.c.
5765 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Changed the client library to use the new ID Cache interface.
5768 Changes around the source tree.
5770 * Added silc_hash_table_rehash_ext to rehash with specific
5771 hash function. Affected file lib/silcutil/silchashtable.[ch].
5773 * Added silc_hash_string_compare to compare two strings in the
5774 hash table. Affected file lib/silcutil/silcutil.[ch].
5776 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added new function silc_idcache_del_by_context into the
5779 lib/silccore/idcache.[ch].
5781 * Changed the server's ID list routines to use the new ID Cache
5782 interface. Changes around the source tree.
5784 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Added silc_hash_table_del[_by_context]_ext functions in to the
5787 lib/silcutil/silchashtable.[ch].
5789 Removed silc_hash_table_find_all* routines and added new
5790 silc_hash_table_find_foreach to replace them.
5792 Added silc_hash_table_replace_ext function as extended
5793 replacing function. Separated the simple hash table interface
5794 from the extended hash table interface in the file
5795 lib/silcutil/silchashtable.h.
5797 * Fixed minor bugs and changed it to use some of the new
5798 hash table functions in lib/silccore/idcache.c
5800 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Added new function silc_hash_table_find_all to return all keys
5803 in the hash table by the specified key. As the hash table is
5804 collision resistant it also makes it possible to have several
5805 duplicate keys in the hash table. This function may be used to
5806 find all of the keys from the hash.
5808 Added user_context arguments to the SilcHashFunction,
5809 SilcHashCompare and SilcHashDestructor to deliver user specified
5812 Added new fuctions silc_hash_table_find[_all]_ext to do
5813 extended lookup with specified hash and compare functions and
5814 specified user contexts.
5816 Added new function silc_hash_table_add_ext to add the key
5817 with specified hash function and user context.
5819 Added new function silc_hash_table_foreach to traverse all
5820 entrys in the hash table. Added SilcHashForeach callback
5823 Added new function silc_hash_table_del_by_context to delete
5824 the entry only if the context associated with the key matches.
5826 Affected files are lib/silcutil/silchashtable.[ch].
5828 * Removed silc_hash_[server/client/channel]_id and added just
5829 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5830 silc_hash_id_compare to compare two ID's using as the hash table
5831 comparison function. Added also silc_hash_data to hash
5832 binary data and silc_hash_data_compare to compare it.
5834 * Removed silc_idlist_find_client_by_hash as it is not needed
5835 anymore. Affected file silcd/idlist.[ch].
5837 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5838 to use internally the SilcHashTable. The new ID Cache is a lot
5839 faster than the old one. Some of the ID Cache interface was also
5840 rewritten and obsolete and stupid functions were removed.
5842 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Added entry_count field to the SilcHashTable to keep the number
5845 of the entries in the table. Implemented the function
5846 silc_hash_table_rehash. Added new function
5847 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5849 Fixed a minor bug in silc_hash_table_free.
5851 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5852 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5853 into the lib/silcutil/silcutil.[ch].
5855 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Implemented a collision resistant hash table into the
5858 lib/silcutil/silchashtable[ch]. See the header and the source
5859 for the SilcHashTable API.
5861 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Merged dotconf version 1.0.2 into lib/dotconf.
5865 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Do not compile anything in lib/silcsim/* if the SIM support
5868 is not enabled. The tree should now compile without problems
5871 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Compiled the SILC under cygwin. Compiled and tested briefly
5874 without problems. More tests needed. The SIMs didn't compile
5877 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5879 * Fixed possible crash in silc_get_username in the
5880 lib/silcutil/silcutil.c.
5882 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Fixed a va_arg in silc/client_ops.c.
5886 * Oops, RC5 routines were named AES and caused some problems
5887 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5889 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added new SilcIDIP structure into the lib/silccore/id.h and
5892 replaced the old `ip' fields from all SILC ID's to that type.
5893 This is a step towards IPv6 support.
5895 The silc_id_get_len takes now the ID as an extra argument.
5896 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5897 both IPv4 and IPv6 based ID's.
5899 The affected files are lib/silccore/id.[ch] and other files
5900 around the tree using these routines.
5902 * Removed the ID length arguments in server from various
5903 silc_server_send_notify_* routines -> they are not needed
5906 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Fixed memory leak in silc_encode_pem_file in the file
5909 lib/silcutil/silcutil.c.
5911 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Check minor version as well in the SKE. Affected files are
5914 silcd/protocol.c and lib/silcclient/protocol.c.
5916 * Added --identifier option to the server so that an identifier
5917 can be when creating the public key for the server. Affected
5918 file is silcd/silcd.c.
5920 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5921 lib/silccrypt/silcpkcs.c.
5923 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Register default ciphers and stuff when using -C option with
5926 the server. Affected file sildc/silcd.c.
5928 * Put back the servers public key filename format, it is better
5929 than the new one. For now, the client keys are saved with the
5930 new filename format. The affected file silc/client_ops.c.
5932 * Implemented the Cipher API for the rest of the ciphers that
5933 did not implement it or implemented it the wrong way.
5935 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Register default ciphers and stuff when using the -S option
5938 in the client. Affected file silc/silc.c. Same also when
5939 creating new key pair with -C option.
5941 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Fixed the silc_verify_public_key client operation function to
5944 save the public keys differently. The fingerprint is now
5945 used as filename and not the hostname. This way also the
5946 client keys are saved uniquely and not with hostnames. The
5947 affected file is silc/client_ops.c.
5949 * Trimmed the silc_hash_fingerprint function to remove extra
5950 whitespaces from the end of the fingerprint. The affected
5951 file is lib/silccrypt/silchash.c.
5955 * Added silc_cipher_register_default function to register all
5956 default ciphers. It can be used when configuration files
5957 does not exist and the application does not want any specific
5958 ciphers in any specific order.
5960 The SilcDList is now used as silc_cipher_list dynamically
5961 allocated cipher list. Removed the static list all together
5962 and now all ciphers must be allocated to the dynamic list.
5963 The silc_cipher_alloc routine was changed to check only the
5966 All silc_cipher_* routines that used to return int returns
5969 The affected files lib/silccrypt/silccrypt.[ch].
5971 * The same thing was done to silc_hash_* as for silc_cipher_*
5972 routines. Affected files lib/silccrypt/silchash.[ch].
5974 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5975 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5976 Added also silc_pkcs_[un]register[_default] functions.
5977 Removed the data_context from the PKCS API.
5979 * Added silc_hmac_register_default function to register default
5980 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5981 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5982 to unregister all hmacs at once.
5984 * Register the default ciphers, hash functions, PKCSs and HMACs
5985 if client's configuration file does not exist. The affected
5988 * The client did not load the hash functions from the SIM
5989 modules at all. Added support for this. Affected file is
5990 silc/clientconfig.c.
5992 * When decoding public key with silc_pkcs_public_key_decode, check
5993 the supported algorithm only if PKCS are registered. Affected
5994 file lib/silccrypt/silcpkcs.c. The same was done with the
5995 silc_pkcs_private_key_decode.
5997 * Fixed the SILC List routines to keep the list always in order.
5998 It used to change the list's order when traversing the list but
5999 not it preserves the order. Affected file lib/trq/silclist.h.
6001 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Added the client library to use the SilcSocketConnection's
6004 reference counter (by silc_socket_dup) to prevent the bug that
6005 the socket object may be freed underneath async operation.
6007 * The name resolv library checking fixes in the configure.in.pre.
6010 * Created new version of the protocol drafts for future
6011 development. The -03 drafts are the ones that will be changed
6012 in the trunk now and the -02 will remain as they are.
6014 * Send list of CUMODE notifys to the router when announcing
6015 the channel users to the router. Affected file silcd/server.c.
6016 If the router receiving channel founder CUMODE for a channel
6017 that already has channel founder it will send CUMODE notify
6018 to the sender to remove the channel founder rights from the
6019 announced client. Affected file silcd/packet_receive.c.
6021 * The CUMODE notify may now use Server ID as well as the entity
6022 who changes the mode. Updated protocool specs.
6024 * Updated INSTALL and README files.
6026 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * New web pages in the http://silc.pspt.fi. The pages was
6033 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Implemented the [DenyConnectin] config section in the server.
6036 Added silc_server_config_denied_conn to check whether incoming
6037 connection is denied. Affected file silcd/serverconfig.[ch].
6039 * Do not check the ports when checking the incoming configuration
6040 data if the port is 0, meaning any. Affected file is
6041 silcd/serverconfig.c.
6043 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Fixed buffer overflow in silc_string_compare in the file
6046 lib/silcutil/silcutil.c.
6048 * Fixed double free in silc_server_command_leave in the file
6051 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Fixed the version checking in the server. Affected file is
6056 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Fixed the configuration data fetching when accepting new
6059 connections in the server. Affected file silcd/server.c.
6061 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Added `sender_entry' argument to the function
6064 silc_server_packet_relay_to_channel so that we can check
6065 whether some destination actually belongs to the same route
6066 the sender belongs (ie, we must not resend the packet to the
6067 sender). Affected file silcd/packet_send.[ch].
6069 * Added `servername' field to the SilcClientEntry in the server
6070 to hold the name of the server where client is from. Affected
6071 file is silcd/idlist.h.
6073 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Moved the channel message encrypting in the router betwen
6076 router connections from silc_server_channel_message to the
6077 silc_server_packet_relay_to_channel since we want to check
6078 whether we have anybody channel before encrypting anything.
6079 Affected files silcd/packet_[receive/send].c.
6081 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Fixed the [AdminConnection] server config section to support
6084 multiple entries. Affected file silcd/serverconfig.c.
6086 * Added support into the server to check the validity of the
6087 incoming connection before executing any KE or authentication
6090 * The connection configuration is now saved to the KE and
6091 connection auth protocol contexts and not fetched anymore in
6092 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6094 * The local hosts listenning address and port is also resolved
6095 now when starting the server. We want to have the socket object
6096 to include the real address and port for the listener. Added
6097 new function silc_net_check_local_by_sock into the files
6098 lib/silcutil/silcnet.[ch].
6100 * Fixed a broadcast bug in server -> do not broadcast if we
6103 * Fixed a routing bug. Do not route broadcast packets ever.
6104 Broadcast packets must be processed always and not routed since
6105 they may be destined to some other host than yourself and thus
6106 would get routed without no good reason. Affected file is
6109 * Added function silc_server_config_is_primary_route to check
6110 whether primary router connection has been configured (a router
6111 configuration that we are initiating). If there is not, we
6112 will assume that there is only two routers in the SILC network
6113 and we will use the incoming router connection as our primary
6114 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6116 * Changed the order of the broadcasting. Broadcast _after_ the
6117 packet has been processed not before. Affected file is
6120 * Fixed a [ClientConnection] parsing bug. The port was never
6121 parsed correctly thus resulting to port 0. Affected file
6122 silcd/serverconfig.c.
6124 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6125 argument and did not set the broadcast packet flag. Affected
6126 file silcd/packet_send.c. Fixed same bug in the function
6127 silc_server_send_notify as well.
6129 * If we receive NEW_ID packet for our own ID in the server, ignore
6132 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Removed the nickname from the Private Message Payload.
6137 Updated the code and the protocol specs.
6139 * Updated protocol specs for submitting to the IETF.
6141 * Tweaked the Random Number Generator a bit. Affected file
6142 lib/silccrypt/silcrng.c. Exported a new function
6143 silc_rng_[global]_add_noise which can be used to add more
6146 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Do not parse packets with different timeout when protocol
6149 is active -> may cause problem with rekey. Affected file
6152 * When server receives signoff notify it must not create
6153 new channel key if the client is on any channels since the
6154 sender of the signoff notify will create it.
6156 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Added printing of error messages during SKE protocol from the
6159 failure packet sent by server during SKE. Affected file
6162 * Removed the client's failure_callback handling with timeout
6163 and handle it immediately when received.
6165 * The SKE library returned wrong type in SUCCESS and FAILURE
6166 packets. They must be 32 bit MSB not 16 bit MSB.
6168 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Ok, rewrote the logic of the re-key and now it seems to work.
6171 I tested it on high traffic with frequent re-keys without
6172 problems. Added hmac_receive (and renamed hmac to hmac_send)
6173 in SilcClientConnection in lib/silcclient/client.h and
6174 in SilcIDListData in silcd/idlist.h. Also, removed the
6175 SilcPacketParserContext's cipher and hmac fields as they are
6176 not needed anymore and actually caused some problems when
6177 the ciphers and hmac's changed underneath the packet parser.
6179 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * If re-key protocol is active then process the incoming packets
6182 synchronously since we must assure that icoming packets encrypted
6183 with the old key is processed before the new keys is set to
6184 use. This is true other packets than for REKEY packets.
6185 Affected file silcd/server.c. The same was done to client library
6186 as well, affected file lib/silcclient/client.c.
6188 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Fixed bug in client and server to accept the force send if
6191 the packet is send from silc_[server/client]_packet_process
6192 function. Otherwise the packets are never delivered, oops.
6194 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Disable force sending of packets when REKEY protocol is active.
6197 We must assure that no packet is sent directly when rekey is
6198 performed. All packets must be sent through packet queue.
6199 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6200 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6201 function is silc_[server/client]_packet_send_real to check
6204 * Replaced the SIM paths from example config files to
6205 /usr/local/modules. Also, make install creates now
6206 /usr/local/silc/logs directory to hold all the SILC server
6209 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Made the configure.in.pre work on Solaris. Patch by salo.
6213 * Made all ciphers compatible with non-x86 machines. Defined
6214 CBC mode macros into lib/silccrypt/ciphers_def.h.
6216 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Fixed the make install.
6220 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * When MAC computation fails the silc_packet_decrypt returned 0
6223 even though it was supposed to return -1. Fixed this. The
6224 affected file is lib/silccore/silcpacket.c.
6226 * Do not replace the config files in /etc/silc (in make install)
6227 if they already exist. Affected file ./Makefile.am.
6229 * Do not send re-key packets immediately but through packet queue.
6230 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6232 * Changed silc_net_check_host_by_sock to return FALSE if the
6233 IP/DNS could not be resolved. Though, it returns the IP address
6234 now even if it could not resolve it (but returns also FALSE).
6235 Affected file lib/silcutil/silcnet.[ch].
6237 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Added silc_pkcs_decode_identifier to decode the public key's
6240 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6241 Added also silc_pkcs_free_identifier. Added also new context
6242 SilcPublicKeyIdentifier.
6244 * Added -S option to the silc client. It is used to dump the
6245 contents of the specified public key file.
6247 * Changed the PKCS api to return the public key length when
6248 setting the public key.
6250 * Fixed a fatal bug in the public and private key file loading.
6251 Affected file lib/silccrypt/silcpkcs.c.
6253 * Execute the packet parsing for client with zero (0) timeout
6254 if the protocol is active. Affected file silcd/server.c.
6256 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Made the key generation options to the silcd program. Added
6259 -C option, equivalent to client's option.
6261 * Added new [ServerKeys] config section to the server. It
6262 configures the server's public and private key.
6264 * Defined generic Public Key Payload into the protocol
6265 specification to send specific type of public keys and
6268 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6269 public key or certificate.
6271 * Implemented the GETKEY command to the server and to the
6272 client library and on user interface.

6280 * Added SilcServerRekey context into silcd/idlist.h.
6282 * Added the PFS support as defined in the specification to the
6283 SKE protocol. Affected files lib/silcske/*.c.
6285 * Added `ske_group' field to the SilcServerRekey context to hold
6286 the number of the SKE group that is used with PFS in re-key.
6287 Affected file silcd/idlist.h.
6289 * Added PFS re-key support to the server. Affected file is
6292 * Added silc_protocol_cancel to cancel execution of the next
6293 state of the protocol. Affected file is
6294 lib/silccore/silcprotocol.[ch].
6296 * Added the re-key support with and without PFS to the client
6297 library. Re-key is performed once in an hour, by default.
6299 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6300 Added silc_client_rekey_callback and silc_client_rekey_final.
6301 Affected files are lib/silcclient/protocol.[ch] and
6302 lib/silcclient/client.[ch].
6304 * Removed the `hmac_key' and `hmac_key_len' fields from the
6305 SilcClientConnection structure; not needed. Affected file is
6306 lib/silcclient/client.h.
6310 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Do not ask whether user wants to use the negotiated private key
6313 for private messages, just use it. Affected file is
6314 silc/local_command.c.
6316 * Added `send_enc_key' and `enc_key_len' fields to the
6317 SilcIDListData structure since they are needed in the re-key
6318 phase. Affected file is silcd/idlist.[ch].
6320 * Implemented the simple re-key protocol into the server.
6321 Affected files silcd/server.c and silcd/protocol.[ch]. The
6322 re-key will be performed once in an hour, by default.
6324 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6325 Added silc_server_rekey, silc_server_rekey_callback and
6326 silc_server_rekey_final.
6328 * Removed Tunneled flag from the protocol. Updated the code
6329 and the specifications.
6331 * Adde `pfs' field to the SilcIDListData to indicate whether
6332 the PFS is to be performed in the re-key. Affected file is
6335 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6338 int64 of at least the xintXX size. If void * is less that 4
6339 bytes uint32 * will be used. Defined bool as boolean.
6341 * Changed _ALL_ unsigned long and unsigned int to uint32,
6342 unsgined short to uint16 in the source tree.
6344 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6345 not handle clients that has entry->data.registered == FALSE.
6346 They are not in the network anymore. Affected file is
6349 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Implemented the sending of the SERVER_SIGNOFF notify in the
6352 server. Affected file is silcd/server.c.
6354 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6355 Added also silc_notify_payload_encode_args into the
6356 lib/silccore/silcnotify.[ch].
6358 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6359 Affected file silcd/packet_receive.c.
6361 * Implemented the SERVER_SIGNOFF notify handling in the client
6362 library. Affected file lib/silcclient/client_notify.c. Also,
6363 implemnted the printing of the SERVER_SIGNOFF info to the
6364 application. Affected file silc/client_ops.c.
6366 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6367 if the deleting was successful. Affected file silcd/idlist.[ch].
6369 * Added support for public key authentication in the connection
6370 authentication protocol in the client library. Affected file
6371 lib/silcclient/protocol.c.
6373 * Changed the server's silc_idlist_get_clients_by_* interface
6374 to support already allocated array so that new entries may be
6375 added to pre-allocated array. Affected file silcd/idlist.[ch].
6376 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6377 and command replies.
6379 * All command reply functions in the server now calls the
6380 pending command callback even if error occured. This way the
6381 error will be delivered to the client as well. Affected files
6382 silcd/command.c and silcd/command_reply.c.
6384 * Fixed INFO command to return local server's info if no server
6385 was provided. Affected file lib/silcclient/command.c.
6387 * Removed RESTART command for good. Updated the code and the
6390 * Rewrote parts of the task system. It is a bit simpler now.
6391 Removed unsued task priorities. The affected files are
6392 lib/silcutil/silctask.[ch].
6394 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Moved the USERS printing from the library to the application.
6397 Affected files lib/silcclient/command.c and silc/client_ops.c.
6399 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added channel key re-key support. The re-key is perfomed
6404 only by the router and is done once in an hour. Added `rekey'
6405 field to the SilcChannelEntry in the server. Affected files
6406 silcd/server.c and silcd/idlist.h.
6408 * Added silc_task_unregister_by_context into the file
6409 lib/silcutil/silctask.[ch].
6411 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Added SILC_UMODE_GONE mode to indicate when the client is not
6414 present in the SILC network. Added also support to the local
6415 command AWAY that will set this mode. Added support of showing
6416 "xxx is gone" in WHOIS command. The USERS command shows the
6417 gone status as well.
6419 * Fixed setting server and router operator privileges in the
6420 server's UMODE command. Affected file silcd/command.c.
6422 * Merged the SKE KE1 and KE2 payloads into one payload. The
6423 new KE payload is equivalent to the old KE2 payload.
6425 Cleaned up the SKE Start Payload parsing. It now uses the
6426 simple buffer unformatting to do the parsing. A lot faster
6429 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6430 to the SKE that is used to indicate whether both of the SKE
6431 parties should perform authentication. By default only the
6432 responder performs authentication. By setting this flag also
6433 the initiator must do authentication. By default it is unset
6434 since in normal SKE case, client to server connection, only
6435 the responder should do authentication. When doing SKE between
6436 two clients both should perform authentication. Updated the
6437 code and the protocol specs.
6439 * A little fix to IDENTIFY command in the server. Search the
6440 client first by hash not nickname. Affected file is
6443 * Fixed the silc_client_close_connection to support closing
6444 the client to client connections wihtout deleting too much
6445 data. Affected file lib/silcclient/client.c.
6447 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6448 are received if protocol used to be active but is not anymore
6449 the application would crash due to NULL pointer dereference.
6450 Affected files silcd/server.c and lib/silcclient/client.c.
6452 * Added `hash' field to the SilcClientConnection to include
6453 the hash function negotiated in the SKE protocol.
6455 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6456 to set the channel founder authentication data. A client can
6457 claim the founder rights later by providing the authentication
6458 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6459 This way the channel founder can regain the channel founder
6460 privileges even it is left the channel. This works only on
6461 local server and the client must be connected to the same
6462 server to be able to regain the founder rights. Updated the
6463 protocol specs accordingly.
6465 Added support to the CMODE command in the client to set the
6466 founder auth data. Read the README to see how to set it.
6468 Added support to the CUMODE command to claim the founder
6469 rights. Read the README to see how to do it.
6471 Added support for the founder authentication to the Channel
6472 Entry in the server. Affected file silcd/idlist.h.
6474 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6475 server's CMODE command. Affected file silcd/command.c.
6477 * Added the following new functions into lib/silccore/silcauth.[ch]:
6478 silc_auth_get_method and silc_auth_get_data.
6480 * The server now saves the remote hosts public key to the
6481 SilcIDListData pointer. Affected file silcd/protocol.c.
6483 * The normal server now does not remove the channel entry from
6484 the cache if the founder authentication data is set. It used
6485 to remove it if the founder was the last one on the channel on
6486 the server and left the channel. The auth data is saved and
6487 if the channel is re-joined later the old entry is used with
6488 the old auth data. Affected files silcd/command_reply.c and
6491 * Removed the `pkcs' field from the SilcIDListData structure
6492 in the server; it is not used. Affected file silcd/idlist.h.
6494 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * Fixed packet processing on slow links. Partial packets were
6497 never re-processed because the incoming data buffer was cleared
6498 by the application. Application must not directly clear the
6499 sock->inbuf, the packet processing routines handle it. Fixed
6500 this in client library and in server.
6502 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Fixed the WHOIS and IDENTIFY send reply function to really
6505 check whether to send list or just one entry. Affected file
6508 * Cleaned up the LEAVE command's channel key distribution. The
6509 affected file silcd/command.c.
6511 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6512 can enforce the channel mode as well. In that case the ID
6513 includes the ID of the server. The code now enforces the
6514 mode change if the router have different mode than the server.
6516 * The notify client operation with CMODE_CHANGE notify can now
6517 return NULL client_entry pointer if the CMODE was not changed
6518 by client. Application must check for this.
6520 * Added <Server ID> argument to INFO command to support server
6521 info fetching by Server ID.
6523 * Added silc_server_announce_get_channel_users to get assembled
6524 packets of channel users of the specified channel. Affected
6525 file silcd/server.[ch].
6527 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6528 was freed underneath the ID Cache.
6530 * Re-announce clients when the server received CHANNEL_CHANGE
6531 notify from the router. Affected file silcd/packet_send.c.
6533 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6536 crashed since it did not handle the fact that there is no cipher
6537 called "3" and didn't check the error condition. Now fixed.
6539 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6540 flag. It can be used to send message requests.
6542 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Implemented the RESTART command in the client.
6546 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6547 notice type messages. Added notice printing to the user
6550 * The channel keys are not re-generated if the channel's mode
6551 is PRIVKEY, ie private key on the channel exists. Affected
6552 files silcd/server.c and silcd/command.c.
6554 * Fixed a little bug in channel message delivery when channel
6555 private keys are set in the server. Affected file is
6556 silcd/packet_send.c.
6558 * Changed the setting on channel->on_channel = TRUE from the
6559 silc_client_save_channel_key to the JOIN command reply. The
6560 key payload is not received if the private channel key is set.
6561 Affected file lib/silcclient/command_reply.c and the
6562 lib/silcclient/client_channel.c.
6564 * When the CMODE_CHANGE notify is sent and the channel private
6565 key mode is removed the channel key must be re-generated in
6566 other cells as well. Added this support for the router in the
6567 silcd/packet_receive.c.
6569 * Added new local command NOTICE to send notice message on
6570 channel. Affected file silc/local_command.[ch].
6572 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added new local command ME to the client. It is used to send
6575 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6576 some action. Affected file silc/local_command.[ch].
6578 * Changed channel_message and private_message client operations
6579 to deliver the message flags to the application. Added also
6580 the `flags' arguments to the silc_client_send_channel_message
6581 and silc_client_send_private_message functions. Affected file
6584 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Redefined the Private Message Payload to support private message
6587 keys and to support the new private message flags. Updated
6588 the protocol specs. Flags makes it possible to have for example
6589 CTCP style messages.
6591 * Added new type SilcPrivateMessagePayload and defined an API
6592 for it in the lib/silcclient/silcprivate.[ch].
6594 * Tested private message private keys successfully. Tested the
6595 private message key set, unset and list commands with the new
6598 * Redefined the Channel Message Payload to include the channel
6599 message flags (equal with private message flags) to support
6600 for example CTCP style messages.
6602 * Defined some of the message (for channel and private message)
6603 flags. Updated the protocol specs and added the flags to the
6604 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6606 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Added SilcKeyAgreementStatus type to the key agreement routines
6609 to indicate the current status and error if one occured.
6610 The status types are defined in the lib/silcclient/silcapi.h.
6612 * Added new local command KEY that is used to set and unset private
6613 keys for channels, set and unset private keys for private messages
6614 with remote clients and to send key agreement requests and
6615 negotiate the key agreement protocol with remote client. The
6616 key agreement is supported only to negotiate private message keys,
6617 it currently cannot be used to negotiate private keys for channels,
6618 as it is not convenient for that purpose.
6620 * Fixed a minor pending callback setting bug in the function
6621 silc_client_get_client_by_id_resolve, now the function works.
6622 Affected file lib/silcclient/idlist.c.
6624 * Added function silc_net_get_local_port to get local bound
6625 port by socket. Added to lib/silcutil/silcnet.[ch].
6627 * Added `sockets' and `sockets_count' fields to the SilcClient
6628 object. They hold the sockets of the listenning sockets in
6629 the client. Listenning sockets may be for example the key
6630 agreement server. Affected file lib/silcclient/client.[ch].
6631 Added functions the silc_client_add_socket and the
6632 silc_client_del_socket. They are exported to the application
6635 * Added ~./silc/clientkeys to support other client's public keys.
6637 * Renamed verify_server_key client operation to verify_public_key
6638 and added one argument to indicate the type of the connection
6639 (server, client etc.).
6641 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Added silc_server_connection_auth_request to handle the
6644 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6645 silcd/packet_receive.[ch].
6647 * Added silc_server_send_connection_auth_request into the
6648 silcd/packet_send.c to send the connection auth request packet.
6650 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6653 * Fixed the public key authentication in responder side in the
6654 server. The `auth_data' pointer includes the SilcPublicKey
6655 not the path to the public key. Affected file silcd/protocol.c.
6657 * Implemented the public key authentication in the initiator side
6658 in the server. Affected file silcd/protocol.c.
6660 * Removed the [RedirectClient] config section from the server
6661 configuration. Is not needed and I don't want to implement it.
6663 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Cleaned up the CMODE command in the server. It now works
6666 correctly and supports all the modes defined in the protocol.
6667 Affected file is silcd/command.c.
6669 * Added `hmac_name' field to the SilcChannelEntry in the server
6670 to hold the default HMAC of the channel. It can be set when
6671 creating the channel (with JOIN command). Affected files
6674 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6675 type to indicate the change of the current cipher and hmac
6676 on the channel. Client can safely ignore the <cipher> argument
6677 (if it chooses to do so) since the CHANNEL_KEY packet will
6678 force the channel key change anyway. The <hmac> argument is
6679 important since the client is responsible of setting the new
6680 HMAC and the hmac key into use.
6682 * Fixed the CMODE command in the client library as well.
6684 * Tested CMODE command in router environment successfully.
6686 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Show the version of the remote client (or server) when connecting
6689 to the server. It is logged to the log file. Affected file
6690 is silcd/protocol.c.
6692 * Fixed the KILLED notify handling in the client library. The
6693 client must be removed from all channels when receiving the
6696 Also, do not remove the client entry when giving the KILL
6697 command but when the KILLED notify is received.
6699 * Removed silc_idlist_find_client_by_nickname from the server.
6700 Not needed anymore. Affected files silcd/idlist.[ch].
6702 * Implemented the CHANNEL_CHANGE notify type handling to the
6703 server. Affected file silcd/server.c.
6707 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added silc_server_send_notify_invite to send the INVITE
6710 notify between routers.
6712 * Implemented the INVITE command correctly to the server.
6714 * Implemented the INVITE notify type handling in the server.
6716 * Implemented the INVITE command to the client library and on the
6719 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Added function silc_server_get_client_resolve to find the
6722 client entry by ID from all ID lists and then resolve it
6723 (using WHOIS) if it cannot be found. Affected file is
6726 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Implemented the BAN command to the client library.
6730 * The JOIN command in the server now checks the invite list
6733 * Changed the silc_command_reply_payload_encode_va and the
6734 silc_command_payload_encode_va to support that if argument is
6735 NULL it ignores and checks the next argument. Affected file
6736 lib/silccore/silccommand.c.
6738 * Added silc_server_send_notify_ban to send the BAN notify
6739 type between routers.
6741 * Chaned the silc_notify_payload_encode to support that if
6742 argument is NULL it ignores and checks the next argument.
6743 Affected file lib/silccore/silcnotify.c.
6745 * Tested ban lists in router environment successfully.
6747 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Implemented BAN command to the server, in silcd/command.[ch].
6751 * Removed the BAN and INVITE_LIST modes from the CMODE command
6754 * Added function silc_string_match to regex match two strings.
6755 Affected files lib/silcutil/silcutil.[ch].
6757 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Redefined parts of the SilcChannelEntry in the server to support
6760 the new ban and invite lists.
6762 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Redefined the INVITE command. The same command can be used to
6765 invite individuals to the channel but also to manage the invite
6766 list of the channel (to add to and remove from the invite list).
6767 Updated the protocol specs.
6769 * Added new command SILC_COMMAND_BAN that can be used to manage
6770 the ban list of the channel. Updated the protocol specs.
6772 * Removed the channel modes: the SILC_CMODE_BAN and the
6773 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6774 in the CMODE command. The equivalent features are now available
6775 using INVITE and BAN commands. Updated the protocol specs.
6777 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6778 in the network about change in the current ban list. The notify
6779 type is not used by the client.
6781 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6782 support the invite lists.
6784 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added new function silc_string_regexify that converts string
6787 including wildcard characters into regex string that can
6788 be used by the GNU regex library. Added into the file
6789 lib/silcutil/silcutil.[ch].
6791 Added silc_string_regex_combine to combine to regex strings
6792 into one so that they can be used as one regex string by
6793 the GNU regex library. Added into the file
6794 lib/silcutil/silcutil.[ch].
6796 Added silc_string_regex_match to match two strings. It returns
6797 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6799 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Imported GNU regex to the soruce tree into lib/contrib.
6802 Fixed some compiler warning from the regex.c.
6804 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Fixed MOTD command in the server to work in router environment.
6808 * Fixed the MOTD command in the client library to support
6809 the server argument in the command.
6811 * Added `nickname_len' argument to the silc_idlist_add_client
6812 in the server, as the `nickname' argument may be binary data
6815 * Added silc_idlist_get_channels to return all channels from
6818 * Implemented LIST command to the server. Affected file is
6821 * Implemented the LIST command to the client library and on the
6824 * Added [<user count>] argument to the LIST command reply.
6825 With private channels the user count is not shown.
6827 * Updated TODO and README.
6829 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6831 * The client entry's data.registered must be TRUE even with
6832 global client entry on global client list. The data.registered
6833 is used to check whether the client is anymore in the network,
6834 for example with WHOWAS command so it must be valid.
6836 * Fixed the WHOWAS command in the server. It now actually works
6837 in router environment. Added function into silcd/command_reply.c
6838 silc_server_command_reply_whowas_save.
6840 * Added silc_idlist_purge function to the silcd/idlist.c
6841 to periodically purge the ID Cache.
6843 * Fixed INFO command in the server. It works now in router
6844 environment. Added <server name> argument to the INFO command
6845 reply. Updated the protocol specs.
6847 * Fixed minor bug in silc_idcache_purge to not purge if the
6848 expire value is zero.
6850 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6851 they were buggy because of the WHOWAS information.
6853 * Fixed local command MSG to handle the async resolving of
6854 the remote client properly. It used to fail the first MSG.
6855 Affected file silc/local_command.c.
6857 * Added `data_len' field to SilcIDCache context.
6859 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Update TODO. Todo in commands in the server.
6863 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6866 used by routers as broadcast packet to inform other routers
6867 about the changed user mode.
6869 Implemented the notify handling in the server. Affected file is
6870 silcd/packet_receive.c. Added the function
6871 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6873 * Added new generic Channel Payload and deprecated the New Channel
6874 Payload. The New Channel Payload is now the generic Channel
6877 * Added new argument `mode' to the silc_server_send_new_channel
6878 as it is required in the Channel Payload now.
6880 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6881 and created a new and real SilChannelPayload to represent the
6882 new generic Channel Payload. Implemented the encode/decode
6883 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6885 * Added silc_server_get_client_channel_list to return the list
6886 of channels the client has joined for WHOIS command reply.
6887 Affected file silcd/server.[ch].
6889 * Implemented the channel list sending in the WHOIS command reply
6890 in server and in the client.
6892 Implemented the channel list displaying on the user interface
6893 as well. Affected file silc/client_ops.c.
6895 * Added silc_channel_payload_parse_list to parse list of Channel
6896 Payloads. It returns SilcDList list of SilcChannelPayloads.
6897 Client for example can use this function to parse the list of
6898 channels it receives in the WHOIS command reply. The caller
6899 must free the list by calling silc_channel_payload_list_free.
6900 Affected files lib/silccore/silcchannel.[ch].
6902 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * Added one new argument <user mode> to the WHOIS command reply
6905 to return the mode of the user in SILC. Updated the protocol
6908 Implemented it to the server and client.
6910 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Fixed the mode printing on the user interface on joining.
6913 Affected file silc/client_ops.c.
6915 * Implemented the UMODE command and user modes in general to the
6916 client library and to the user interface.
6918 * Implemented the UMODE command to the server.
6920 * The server now sends UNKNOWN_COMMAND error status if client sends
6921 unknown command. Affected file silcd/command.c.
6923 * All server commands now handle the command identifier the right
6924 way when sending the command reply to the client. The client can
6925 use to identify the command replies with the identifier.
6927 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6929 * Added silc_server_get_client_route to resolve the route to
6930 the client indicated by the client ID. Affected file is
6933 * Added silc_server_relay_packet as general function to relay
6934 packet to arbitrary destination. This deprecates functions
6935 like _send_private_message_key, _relay_notify etc. Affected
6936 file is silcd/packet_send.[ch].
6938 Removed silc_server_send_key_agreement,
6939 silc_server_send_private_message_key and
6940 silc_server_packet_relay_notify functions from the file
6941 silcd/packet_send.[ch].
6945 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6946 server. Affected file silcd/packet_receive.[ch].
6948 * Implemented the KILL command to the client. Implemented the
6949 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6950 Affected files lib/silcclient/command[_reply].c and
6951 lib/silcclient/client_notify.c. Implemented the KILL notify
6952 printing in the user inteface.
6954 * Fixed a lot silc_parse_nick memory leaks from the client
6955 library in the file lib/silcclient/command.c.
6957 * Changed the silc_server_send_notify_on_channels's `sender'
6958 argument from SilcSocketConnection to SilcClientEntry to
6959 check the sender as entry and not as connection object and not
6960 to send to the client provided as argument. The affected file
6961 is silcd/packet_send.[ch].
6963 * The notify packets that are destined directly to the client used
6964 to not to be processed by the server. Now changed that and the
6965 server processes all notify packets. After relaying the packet
6966 to the client the notify packet is processed in the server.
6968 * The silc_server_free_client_data now checks whether there is
6969 pending outgoing traffic for the client and purges the data to
6970 the network before removing the client entry.
6972 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6975 an client is killed from the SILC Network. Updated the protocol
6978 Added new function silc_server_send_notify_killed to the
6979 silcd/packet_send.[ch].
6981 * Added function silc_server_packet_relay_notify to relay notify
6982 packets that are destined directly to a client. In this case
6983 the server does not process the notify packets but merely relays
6984 it to the client. Affected file silcd/packet_send.[ch].
6986 Added also silc_server_packet_process_relay_notify to check
6987 whereto relay the notify. Affected file is
6988 silcd/packet_receive.[ch].
6990 * Implemented the KILL command to the server.
6994 * Added the backup schema desgined last fall to the protocol
6995 specs for everyone to see. The specification is in the
6996 *-spec-xx.txt draft and the packet type definitions for the
6997 backup routers is in *-pp-xx.txt draft. Thusly, added also
6998 new packet type SILC_PACKET_CELL_ROUTERS.
7000 * A big security problem in the implementation discovered. The
7001 signoff of an client did not cause new channel key generation
7002 which it of course should've done. The channel keys must be
7003 always re-generated when client leaves (or signoffs) the channel.
7004 The silc_server_remove_from_channels funtion now handles
7005 the channel key re-generation.
7007 * Added `sender' argument to the silc_server_send_notify_on_channels
7008 to not to send the client provided as argument. Affected file
7009 silcd/packet_send.[ch].
7011 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Implemented OPER and SILCOPER commands into the server and
7016 * Added silc_auth_verify and silc_auth_verify_data to verify
7017 the authentication directly from the authentication payload.
7018 It supports verifying both passphrase and public key based
7019 authentication. Affected file lib/silccore/silcauth.[ch].
7021 * Added `hash' field to the SilcIDListData structure. It is the
7022 hash negotiated in the SKE protocol. Affected file is
7025 * Slight redesigning of the SilcAuthPayload handling routines.
7026 Do not send SilcPKCS but SilcPublicKey as argument.
7028 * Implemented the public key authentication support to the
7029 serverconfig. The public key is loaded from the provided path
7030 and saved as authentication data to void * pointer. Thus,
7031 changed the unsigned char *auth_data to void *auth_data;
7033 * Fixed SHUTDOWN command to send the reply before the server
7034 is shutdown. :) Affected file silcd/command.c.
7036 * Fixed fatal bug in CONNECT command. The hostname was invalid
7037 memory and server crashed. Affected file silcd/command.c.
7039 * Fixed fatal bug in CLOSE command. The server_entry became
7040 invalid but was referenced later in the command. Affected file
7043 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Fixed fatal bug in failure packet handling. Server ignored
7046 the failure and thus crashed when it came.
7050 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7053 that the command may be executed only once in (about) 2 seconds.
7054 The old SILC_CF_LAG flag is same but allows command bursts up
7055 to five before limiting.
7057 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7058 server code. Various commands now includes the CF_LAG_STRICT
7059 flag to disallow any kind of miss-use of the command.
7061 * Fixed the silc_buffer_unformat to not to allocate any data
7062 if the length of the data is zero. It used to allocate the
7063 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7065 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Changed the format of AdminConnection configuration section
7068 in the server. Added username of the admin to the format.
7069 Affected files silcd/serverconfig.[ch].
7071 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7072 to return admin configuration data by host, username and/or
7075 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7077 * Implemented WHOWAS command to the server. Added the functions:
7079 silc_server_command_whowas_parse,
7080 silc_server_command_whowas_send_reply,
7081 silc_server_command_whowas_from_client and
7082 silc_server_command_whowas_from_server
7084 * Added <Client ID> argument to the WHOWAS command reply. Updated
7085 the protocol specs accordingly.
7087 * Implemented WHOWAS command and command_reply to the client
7090 Implemented the WHOWAS printing on the user interface.
7092 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Added new argument to the WHOWAS command reply, the real name.
7095 It is an optional argument. Updated the protocol specs.
7097 * Added SilcIDCacheDestructor callback that is registered when
7098 the SilcIDCache is allocated. The callback is called when
7099 an cache entry in the ID Cache expires, or is purged from the
7100 cache. Added into lib/silccore/idcache.[ch].
7102 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7103 to destruct the client entries when the cache entry expires.
7104 Other ID Cache's in server and in the client library ignores
7107 * If the ID Cache entry's `expire' field is zero then the entry
7108 never expires. Added boolean `expire' argument to the
7109 silc_idcache_add function in the lib/silccore/idcache.[ch].
7110 If it is TRUE the default expiry value is used.
7112 * Added silc_server_free_client_data_timeout that is registered
7113 when client disconnects. By default for 5 minutes we preserve
7114 the client entry for history - for WHOWAS command.
7116 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added support to the server to enforce that commands are not
7119 executed more than once in 2 seconds. If server receives
7120 commands from client more frequently, timeout is registered
7121 to process the commands. Affected file silcd/command.c.
7122 Added new function silc_server_command_process_timeout.
7124 * Changed NICK_NOTIFY handling in client library to check that
7125 if the client's nickname was changed, so there is no need to
7126 resolve anything from the server.
7128 * Removed error printing from the WHOIS and IDENTIFY commands.
7129 If error occurs then it is ignored silently in the client library.
7130 The application, however, may map the received error to
7131 human readable error string. The application currently maps
7132 the NO_SUCH_NICKNAME error to string.
7134 * Made the command status message public to the application. Moved
7135 them from lib/silcclient/command_reply.c to
7136 lib/silcclient/command_reply.h. The application can map the
7137 received command status to the string with the
7138 silc_client_command_status_message function.
7140 * Added check to the server to check that client's ID is same
7141 as the Source ID in the packet the client sent. They must
7144 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Added dist-bzip hook to the Makefile.am to make bzip2
7147 compressed distributions.
7149 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7151 * Server now enforces the maximum length for the nickname and
7152 the channel as protocol specification dictates. 128 bytes for
7153 nickname and 256 bytes for channel name.
7155 * Moved the WHOIS printing to the application. The client libary
7156 does not print out the WHOIS information anymore, the application
7157 must do it. Renamed silc_client_command_reply_whois_print to
7158 the silc_client_command_reply_whois_save.
7160 The client's idle time is also sent to the application now, and
7161 the idle is shown on screen.
7163 * Added silc_client_command_reply_identify_save to save the
7164 received IDENTIFY entries.
7166 * Do not check for channel private keys in message sending and
7167 reception if the channel does not have the PRIVKEY mode set.
7168 Affected file lib/silclient/client_channel.c.
7170 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7173 just surfaced after chaning the JOIN procedure.
7175 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added silc_client_get_clients_by_list to get client entries
7178 from Client ID list, that is returned for example by JOIN
7179 and USERS command replies. The application should use this
7180 function for example when JOIN command reply is received to
7181 resolve the clients already on the channel (library does not
7182 do that anymore as USERS command reply is not used in the JOIN
7183 procedure anymore). Affected files lib/silcclient/silcapi.h and
7184 lib/silcclient/idlist.c.
7186 * JOIN command reply and USERS command reply returns now SilcBuffer
7187 pointers instead of unsigned char pointers when returning
7188 the client list and mode list.
7190 * Added <Client ID> argument to the JOIN command reply, mainly
7191 for the server to identify for which client the command was
7192 originally sent. Updated protocol specs accordingly.
7194 * Added SilcDlist private_key pointer to the SilcChannelEntry
7195 in the client to support the channel private keys. Affected
7196 file is lib/silcclient/idlist.h.
7198 * Added SilcChannelPrivateKey argument to the function
7199 silc_client_send_channel_message so that application can choose
7200 to use specific private ke if it wants to. If it is not provided,
7201 the normal channel key is used, unless private keys are set.
7202 In this case the first (key that was added first) is used
7203 as the encryption key.
7205 * Implemented the support for channel private key handling.
7206 Implemented the following functions:
7208 silc_client_add_channel_private_key,
7209 silc_client_del_channel_private_keys,
7210 silc_client_del_channel_private_key,
7211 silc_client_list_channel_private_keys and
7212 silc_client_free_channel_private_keys
7214 Affected file lib/silcclient/client_channel.c.
7216 * Added the support for the private keys in the channel message
7217 sending and encryption and in the message reception and
7218 decryption. Affected funtions are
7219 silc_client_send_channel_message and silc_client_channel_message.
7221 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added SKE's key verify callback to the client library's
7224 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7226 * Removed the statement that server (or router) must send USERS
7227 command reply when joining to the channel so that the client
7228 knows who are on the channel. Instead, the client list and
7229 client's mode list is now sent in the JOIN command reply to the
7230 client who joined channel. This is better solution.
7232 * Added function silc_server_get_users_on_channel and function
7233 silc_server_save_users_on_channel to the silcd/server.[ch].
7235 * Removed function silc_server_command_send_users from the
7238 * Do not show topic on the client library anymore. The topic is
7239 sent in the command reply notify to the application and the
7240 application must show the topic now.
7242 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Added client searching by nickname hash into the IDENTIFY and
7245 WHOIS commands in the server as they were clearly missing from
7246 them. Affected file is silcd/command.c.
7248 * Fixed a bug in private message receiving in the client library.
7249 The remote ID was freed and it wasn't supposed, now it is
7252 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Minor fix to the channel payload; allocate the data area, as it
7255 needs to be of specific length.
7257 * If the key agreement port is zero then the operating
7258 system will define the bound port. Affected files are
7259 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7261 * Added new function silc_channel_payload_decrypt into the file
7262 lib/silccore/silcchannel.[ch].
7264 * Moved the channel message etc, check from silc_packet_decrypt
7265 to applications. The library calls now a generic
7266 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7267 when the packet is either normal or special. This was done to
7268 allow more wide range of checking that was not allowed when
7269 the code was in library. Now applications can do virtually any
7270 checks to the packet and return to the library the decision how
7271 the packet should be processed. Affected files are
7272 lib/silccore/silcpacket.[ch].
7274 Added silc_server_packet_decrypt_check to the server and
7275 silc_client_packet_decrypt_check to the client library.
7277 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7278 to send with specified source and destination information.
7280 * Channel message delivery between routers was broken after the
7281 channel key distribution was fixed earlier. The channel key
7282 was used be to distributed to other routers as well which is not
7283 allowed by the protocol. Now this is fixed and channel keys
7284 really are cell specific and the channel message delivery between
7285 routers comply with the protocol specification.
7287 * Fixed various commands in server to check also the global list
7288 for the channel entry and not just the local list. The affected
7289 file silcd/command.c.
7291 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Added assert()s to buffer formatting and unformatting routines
7294 to assert (if --enable-debug) when error occurs. Affected
7295 file: lib/silcutil/silcbuffmt.c.
7297 * Changed to auto-reconnect to check whether the remote host is
7298 router and register the re-connect timeout if it is. It used
7299 to check that whether we are normal server, but router must do
7300 auto-reconnect with another router as well. Affected file
7303 * Removed the [<key len>] option from CMODE command as the cipher
7304 name decides the key length, nowadays. See the defined ciphers
7305 from the protocol specification.
7307 * Added [<hmac>] option to the CMODE command to define the HMAC
7308 for the channel. Added SILC_CMODE_HMAC channel mode.
7310 * Added [<hmac>] option for the JOIN command so that user can
7311 select which HMAC is used to compute the MACs of the channel
7314 * Added Hmac field to the Channel Message Payload. The integrity
7315 of plaintext channel messages are now protected by computing
7316 MAC of the message and attaching the MAC to the payload. The
7317 MAC is encrypted. Now, it is clear that this causes some
7318 overhead to the size of the packet but rationale for this is that
7319 now the receiver can verify whether the channel message decrypted
7320 correctly and also when private keys are set for the channel the
7321 receiver can decrypt the packet with several keys and check from
7322 the MAC which key decrypted the message correctly.
7324 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7325 lib/silccrypt/silccipher.[ch].
7327 * Added silc_hash_len to return the digest length into the
7328 lib/silcrypt/silchash.[ch].
7330 * Rewrote parts of Silc Channel Payload interface in the
7331 lib/silccore/silcchannel.[ch]. The encode function now also
7332 encrypts the packet and parse function decrypts it.
7334 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Fixed a minor formatting bug in the SKE's key material processing.
7337 It actually might have processed the keys wrong way resulting
7340 * Redefined the mandatory HMAC algorithms and added new algorithms.
7341 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7342 and hmac-md5 truncated to 96 bits. The mandatory is now
7343 hmac-sha1-96. Rest are optional (including the one that used
7344 to be mandatory). Rationale for this is that the truncated HMAC
7345 length is sufficient from security point of view and can actually
7346 make the attack against the HMAC harder. Also, the truncated
7347 HMAC causes less overhead to the packets. See the RFC2104 for
7350 * Added new [hmac] configuration section. The SKE used to use
7351 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7352 is of course wrong. The official names that must be proposed in
7353 the SKE are the ones defined in the protocol specification
7354 (hmac-sha1-96 for example). The user can configure any hmac
7355 using any hash function configured in the [hash] section. At
7356 least, the mandatory must be configured.
7358 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7360 * Added HMAC list to the SKE proposal list. It has now both
7361 hash algorithm list and HMAC list. This makes the protocol
7362 incompatible with previous versions. The SKE now seems to work
7363 the way it is supposed to work, for the first time actually.
7365 * Defined plain Hash algorithms to the protocol specification.
7368 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Implemented support for key agreement packets into the server.
7371 Added functions silc_server_key_agreement and
7372 silc_server_send_key_agreement. Other than these functions,
7373 server has nothing to do with this packet.
7375 * Added support for private message key packets into the server.
7376 Added functions silc_server_private_message_key and
7377 silc_server_send_private_message_key.
7381 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7382 called in the protocol's final callback instead in the END
7383 protocol state. This makes a little more sense and in the same
7384 time in client we can use the same protocol routines for normal
7385 key exchange and to key agreement packet handling as well.
7387 * Added to both client's and server's KE protocol context the
7388 SilcSKEKeyMaterial pointer to save the key material. We will
7389 bring the key material to the protocol's final callback by doing
7390 this. The final callback must free the key material.
7392 * Added SKE's packet_send callback into client's KE protocol
7393 context so that the caller can choose what packet sending function
7394 is used. This way we can use different packet sending when
7395 doing normal SKE when doing key agreement packet handling (in
7396 the key agreement packet handling we do not want to encrypt
7399 * Implemented the responder side of the key agreement routines
7400 in the client. The client can now bind to specified port and
7401 accept incoming key negotiation. The key material is passed
7402 to the application after the protocol is over.
7404 * Implemented the processing of incoming Key Agreement packet
7405 in the client. Added function silc_client_key_agreement to
7408 * Implemented the intiator side of the key agreement routines
7409 in the client. The client can now initiate key agreement with
7410 another remote client. The key material is passed to the
7411 application after the protocol is over.
7413 * Created client_keyagr.c to include all the key agreement
7416 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7417 SILC_TASK_CALLBACK except that it is not static.
7419 * Created client_notify.c and moved the Notify packet handling
7420 from the client.[ch] into that file.
7422 * Created client_prvmsg.c and moved all private message and
7423 private message key routines from the client.[ch] into that file.
7425 * Create client_channel.c and moved all channel message and
7426 channel private key routines from the client.[ch] into that file.
7428 * Changed silc_client_get_client_by_id_resolve to resolve with
7429 WHOIS command instead of IDENTIFY command, in the file
7430 lib/silclient/idlist.c.
7432 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7434 * Implemented the SKE's responder side to the Client library.
7436 * When FAILURE is received to the protocol do not trust it
7437 blindly. Register a timeout to wait whether the remote closes
7438 the connection as it should do it, only after that process the
7439 actual failure. This was changed to both client and server.
7441 * Added client_internal.h to include some of the structures
7442 there instead of client.h in lib/silcclient/.
7444 * Added function silc_task_unregister_by_callback to unregister
7445 timeouts by the callback function.
7447 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Some "Incomplete WHOIS info" errors has been appearing on the
7450 log files. Took away the entry->userinfo check from WHOIS
7451 reply sending. The entry->userinfo is now " " if client did not
7452 provide one. I thought this was fixed earlier but something
7453 is wrong still. Let's see if the error still appears.
7455 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Fixed a minor bug in the login when the channel key is
7458 re-generated in the server. It used to generate the key in
7459 wrong order and thus caused problems in the channel traffic.
7461 * Fixed a minor bug in channel key distsribution after
7462 KICK command. The key was not sent to the router even though
7465 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7467 * Added silc_ske_process_key_material_data as generic routine
7468 to process any key material as the SILC protocol dictates. The
7469 function is used by the actual SKE library but can be used by
7470 applications as well. This relates to the private message keys
7471 and the channel private keys since they must be processed the
7472 same way the normal SILC session keys. The protocol dictates
7473 this. Affected files: lib/silcske/silcske.[ch].
7475 Added also silc_ske_free_key_material to free the
7476 SilcSKEKeyMaterial structure.
7478 * Defined silc_cipher_set_key function to set the key for
7479 cipher without using the object's method function. The affected
7480 files: lib/silccrypt/silccipher.[ch].
7482 * Implemented silc silc_client_add_private_message_key,
7483 silc_client_add_private_message_key_ske,
7484 silc_client_del_private_message_key,
7485 silc_client_list_private_message_keys and
7486 silc_client_free_private_message_keys functions in the
7489 Added functions silc_client_send_private_message_key to send
7490 the Private Message Key payload and silc_client_private_message_key
7491 to handle incoming Private Message Key payload.
7493 * Added Cipher field to the Private Message Key payload to set
7494 the cipher to be used. If ignored, the default cipher defined
7495 in the SILC protocol (aes-256-cbc) is used.
7497 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Removed lib/silcclient/ops.h file.
7501 Redefined parts of the SILC Client Library API. Created new
7502 file silcapi.h that deprecates the ops.h file and defines the
7503 published Client Library API. Defined also private message key
7504 API and channel private key API into the file.
7506 This is the file that the application must include from the
7507 SILC Client Library. Other files need not be included by
7508 the application anymore.
7510 * Added new key_agreement client operation callback and also
7511 defined the Key Agreement library API for the application.
7513 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7516 is used by clients to request key negotiation between another
7517 client in the SILC network. If the negotiation is started it
7518 is performed using the SKE protocol. The result of the
7519 negotiation, the secret key material, can be used for example
7520 as private message key.
7522 Implemented the Key Agreement payload into the files
7523 lib/silccore/silauth.[ch].
7525 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Redefined ciphers for the SILC protocol. Added some new ciphers
7528 and defined the key lengths for the algorithms. Changed the
7529 code accordingly. The default key length is now 256 bits.
7531 * Fixed SKE key distribution function silc_ske_process_key_material
7532 when the key length is more than 128 bits. The default key
7533 length in SILC is now 256 bits.
7535 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7536 to indicate unsupported algorithm.
7538 * Renamed rijndael.c to aes.c and all functions as well.
7540 * Fixed a long standing channel key setting bug in client library.
7541 Weird that it has never surfaced before.
7543 * Fixed bug in channel deletion. If the entire channel is removed
7544 then it must also delete the references of the channel entry
7545 from the client's channel list as the client's channel entry and
7546 the channel's client entry share same memory.
7548 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Implemented CONNECT and SHUTDOWN commands in the client.
7552 * Implemented CLOSE command to the client.
7554 * Added the function silc_idlist_find_server_by_name into the
7555 files silcd/idlist.[ch].
7557 Added the function silc_idlist_find_server_by_conn into the
7558 files silcd/idlist.[ch].
7560 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * DIE command was renamed to SHUTDOWN. Updated the both code
7565 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7566 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7568 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7571 * Added function silc_server_create_connection function to create
7572 connection to remote router. My server implementation actually
7573 does not allow router to connect to normal server (it expects
7574 that normal server always initiates the connection to the router)
7575 so the CONNECT command is only good for connecting to another
7578 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7580 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7581 or some other client was kicked from the channel.
7583 Implemented the handling of the notify type to both client
7586 Implemented silc_server_send_notify_kicked to send the KICKED
7587 notify. It is used to send it to the server's primary router.
7589 * Implemented the KICK command into server and client.
7591 * Added `query' argument to the silc_idlist_get_client function
7592 to indicate whether to query the client from server or not if
7595 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7596 to indicate that the client is not channel founder.
7600 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Removed the rng context from SilcPacketContext structure and
7603 changed that the packet routine uses the Global RNG API.
7605 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7607 * Added support for quit message that client can "leave" on the
7608 channel when it quits the SILC. It is ditributed inside the
7609 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7611 Added silc_server_free_client_data that will take the
7612 signoff message as argument.
7614 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7616 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Updated parts of the protocol specification to keep it up
7621 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7624 payloads in one packet.
7626 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7627 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7628 use now the new List flag.
7630 * Also deprecated the following packet types: REPLACE_ID,
7631 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7633 * Added list support for Notify packet in server.
7635 * Added silc_server_send_notify_channel_change to send the
7636 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7637 the silc_server_send_replace_id.
7639 * Added silc_server_send_notify_nick_change to send the
7640 NICK_CHANGE notify type. Deprecates the function
7641 silc_server_send_replace_id.
7643 * Added silc_server_send_notify_join to send the JOIN notify type.
7644 Deprecates the function silc_server_send_new_channel_user.
7646 * Added silc_server_send_notify_leave to send LEAVE notify type.
7647 Deprecates the function silc_server_send_remove_channel_user.
7649 * Added silc_server_send_notify_cmode and
7650 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7651 types. Deprecates the silc_server_send_set_mode function.
7653 * Added SERVER_SIGNOFF notify type to indicate that server has
7654 quit. This means that all clients on the channel from that
7655 server will drop. This can be also used when netsplit happens.
7657 Deprecated REMOVE_ID packet type since it is not needed anymore
7660 Added silc_server_send_notify_server_signoff to send the
7661 SERVER_SIGNOFF notify type. Deprecates the function
7662 silc_server_send_remove_id.
7664 Added also silc_server_send_notify_signoff to send the
7665 SIGNOFF notify type.
7667 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7668 SILC protocol from this day on. Changed the protocol
7669 specification as well.
7671 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7672 notify type. It is used between routers to notify about
7673 topic changes on a channel.
7675 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7678 * Partly updated the protocol specification to comply with the
7679 changes now made. It is still though a bit outdated.
7681 * The JOIN notify type now takes one extra argument <Channel ID>.
7682 The packet used to be destined to the channel but now the
7683 JOIN type may be sent as list thus it is impossible to
7684 destine it to any specific channel. By adding this argument
7685 it is again possible.
7687 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7689 * Added CREDITS file. The CHANGES and CREDITS file will appear
7690 in the distribution as well.
7692 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7694 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7695 types in the server's silcd/packet_receive.c.
7697 * Implemented CMODE and CUMODE to work in router environment.
7699 * Fixed minor encoding and decoding buglet from the
7700 lib/silccore/silcmode.c.
7702 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7705 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7707 * Changed all SilcConfigServer* and silc_config_server* to
7708 SilcServerConfig* and silc_server_config*, respectively.
7711 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Associated the ID (client or server ID) to the Authentication
7714 Payload to avoid any possibility of forging. Updated the
7715 protocol specification and the code accordingly.
7717 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * The RSA key length is now save to the RsaKey context in the
7720 key generation process in lib/silccrypt/rsa.c. The key length
7721 is now used to figure out the maximum size of the block allowed
7722 to be encrypted/signed.
7724 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7725 is equivalent to the silc_mp_mp2bin but does not allocate any
7728 * Changed silc_mp_mp2bin API to take length argument. If it is
7729 non-zero then the buffer is allocated that large. If zero, then
7730 the size is approximated using silc_mp_sizeinbase, which however
7733 * Created Global RNG API which is global RNG that application can
7734 initialize. After initializing, any routine anywhere in the
7735 code (including library) can use RNG without allocating a new
7736 RNG object. This was done to allow this sort of use of the
7737 RNG in code that has no chance to allocate RNG object. All
7738 applications currently allocate this and many routines in the
7739 library use this. Affected file lib/silccrypt/silcrng.[ch].
7741 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7742 it to use the Global RNG API.
7744 * Defined Authentication Payload into protocol specification that
7745 is used during SILC session to authenticate entities. It is
7746 used for example by client to authenticate itself to the server
7747 to obtain server operator privileges.
7749 Implemented this payload into the lib/silccore/silcauth.[ch].
7750 Implemented also routines for public key based authentication
7751 as the new protocol specification dictates.
7753 Moved definitions of different authentication methods from
7754 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7756 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7757 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7758 silc_pkcs_verify_with_hash functions into the file
7759 lib/silccrypt/silcpkcs.[ch].
7761 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7763 * The client entry's userinfo pointer must be always valid.
7764 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7765 will fail since it requires the userinfo. Now, the userinfo
7766 is allocated as "" if actual userinfo does not exist. Actually,
7767 it must exist and it is totally Ok to drop client connections
7768 that does not announce the userinfo. However, we will make
7769 this workaround for now.
7771 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7772 to return the remote port by socket.
7774 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7777 SILC_SERVER_PENDING_EXEC and added an new macro
7778 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7779 data or when error occurs while processing the pending command.
7781 Added new argument `destructor' into silc_server_command_pending
7782 and to the SilcServerCommandPending object. This destructor is
7783 now called after calling the pending callback or if error occurs
7784 immediately. If error occurs the actual pending callback won't
7785 be called at all - only the destructor. The destructor may be
7786 NULL if destructor is not needed.
7788 All this applies for client library code as well. Similar
7789 changes were made there as well for the pending commands.
7791 In the client, the application must now allocate the
7792 SilcClientCommandContext with the silc_client_command_alloc
7795 * Added reference counter to the SilcServerCommandContext. Added
7796 function silc_server_command_alloc and silc_server_command_dup
7799 Same type of functions added to the client library for the same
7802 * Removed the cmd_ident from IDListData away since it is now
7803 global for all connections. It is the command identifier used
7804 in command sending and with pending commands. The affected file
7807 * Added reference counter to the SilcSocketConnection objecet to
7808 indicate the usage count of the object. The object won't be
7809 freed untill the reference counter hits zero. Currently only
7810 server uses this, and client ignores it. The client must be
7811 set to use this too later. The affected files are
7812 lib/silccore/silcsockconn.[ch]. Added also the function
7813 silc_socket_dup to increase the reference counter.
7815 This was mainly added because it is possible that the socket
7816 is removed underneath of pending command or other async
7817 operation. Now it won't be free'd and proper DISCONNECTING
7818 flags, etc. can be set to avoid sending data to connection that
7819 is not valid anymore.
7821 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7822 the connection. After that it sets SILC_SET_DISCONNECTED.
7823 It is, however, possible that the socket data is not still freed.
7824 The silc_server_packet_process now checks that data is not
7825 read or written to connection that is DISCONNECTED. The socket
7826 get's freed when the reference counter hits zero.
7828 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7830 * Changed the client operation API: channel_message operation's
7831 `sender' is now the client entry of the sender, not the nickname
7832 and the `channel' is the channel entry, not the channel name.
7834 In the private_message operation the `sender' is now also the
7835 client entry of the sender not the nickname.
7837 Affected file is lib/silcclient/ops.h and all applications
7838 using the client operations.
7840 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7842 * Moved the calling of ops->connect() from connect_to_server_final
7843 into receive_new_id functin since that is the point when the
7844 client is actually allowed to send traffic to network. The
7845 affected file is lib/silcclient/client.c.
7847 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7850 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7851 (if needs broadcasting) instead of broadcasting the packets one
7852 by one which would make a burst in the network traffic.
7854 * Added `broadcast' argument to the functions in silcd/server.[ch]
7855 silc_server_create_new_channel[_with_id] to indicate whether
7856 to send New Channel packet to primary router.
7858 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Added new function into the silcd/server.[ch] files:
7861 silc_server_create_new_channel_with_id to create new channel with
7862 already existing Channel ID.
7864 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7865 lib/silccore/silcpacket.h. This packet is used t send list of
7866 Set Mode payloads inside one packet. Server uses this to set
7867 the modes for the channels and clients on those channels, that it
7868 announced to the router when it connected to it. The protocol
7869 specification has been updated accordingly.
7871 * The silc_server_new_channel did not handle the packet coming
7872 from normal server as it normally does not send that. However,
7873 when it announces its channels it does send it. Implemented
7874 the support for that.
7876 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7877 into the file lib/silccore/id.h.
7879 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7881 * Fixed memory leaks in the functions silc_idlist_del_client,
7882 silc_idlist_del_channel and silc_idlist_del_server in the file
7883 silcd/idlist.c. All of those leaked like a sieve.
7885 * Fixed some small memory leaks in the client's function
7886 silc_client_notify_by_server.
7888 * Added functions into silcd/server.c: silc_server_announce_clients,
7889 silc_server_announce_channels and silc_server_announce_server.
7890 These functions are used by normal and router server to announce
7891 to its primary router about clients, channels and servers (when
7892 router) that we own. This is done after we've connected to the
7895 These functions effectively implements the following packet types:
7896 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7897 and SILC_PACKET_NEW_ID_LIST.
7899 * Added new functions into the silcd/packet_receive.[ch]:
7900 silc_server_new_id_list, silc_server_new_channel_list and
7901 silc_server_new_channel_user_list to handle the incoming
7902 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7904 * Added support of changing Channel ID in the function
7905 silc_server_replace_id. If the server that announces a channel
7906 to the router already exists in the router (with same name but
7907 with different Channel ID), router is responsible to send
7908 Replace ID packet to the server and force the server to change
7909 the Channel ID to the one router has.
7911 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7912 client that the Channel ID has been changed by the router. The
7913 normal server sends this to the client. Client must start using
7914 the new Channel ID as the channel's ID.
7916 Implemented handling of this new type into lib/silcclient/client.c
7917 into the function silc_client_notify_by_server.
7919 * Added new function silc_idlist_replace_channel_id into the files
7920 silcd/idlist.[ch] to replace the Channel ID.
7922 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Call silc_server_command_identify_check always when processing
7925 the IDENTIFY command in silcd/command.c
7927 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7930 send keepalive packets. The packet can be sent by clients,
7931 servers and routers.
7933 Added function silc_socket_set_heartbeat into the file
7934 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7935 If not set, the heartbeat is not performed. The actual
7936 heartbeat is implemented in the low level socket connection
7937 library. However, application is responsible of actually
7940 Added silc_server_send_heartbeat to send the actual heartbeat
7941 packet into silcd/packet_send.[ch]. Server now performs
7942 keepalive with all connections.
7944 * Added silc_task_get_first function into lib/silcutil/silctask.c
7945 to return the timeout task with shortest timeout. There was a bug
7946 in task unregistration that caused problems. TODO has been
7947 updated to include that task system must be rewritten.
7949 * The client library will now resolve the client information when
7950 receiving JOIN notify from server for client that we know but
7951 have incomplete information.
7953 * Rewrote parts of silc_server_remove_from_channels and
7954 silc_server_remove_from_one_channel as they did not remove the
7955 channel in some circumstances even though they should've.
7957 * Encryption problem encountered in server:
7959 The LEAVE command used to send the Channel Key packet to the
7960 router immediately after generating it. However, the code
7961 had earlier sent Remove Channel user packet but not immediately,
7962 ie. it was put to queue. The order of packets in the router
7963 was that Channel Key packet was first and Remove Channel User
7964 packet was second, even though they were encrypted in the
7965 reverse order. For this reason, MAC check failed. Now, this
7966 is fixed by not sending the Channel Key packet immediately but
7967 putting it to queue. However, this is more fundamental problem:
7968 packets that are in queue should actually not be encrypted
7969 because packets that are sent immediately gets encrypted
7970 actually with wrong IV (and thus MAC check fails). So, packets
7971 that are in queue should be encrypted when they are sent to
7972 the wire and not when they put to the queue.
7974 However, the problem is that the current system has not been
7975 designed to work that way. Instead, the packet is encrypted
7976 as soon as possible and left to the queue. The queue is then
7977 just purged into wire. There won't be any fixes for this
7978 any time soon. So, the current semantic for packet sending
7981 o If you send packet to remote host and do not force the send
7982 (the packet will be in queue) then all subsequent packets to the
7983 same remote host must also be put to the queue. Only after the
7984 queue has been purged is it safe again to force the packet
7987 o If you send all packets immediately then it safe to send
7988 any of subsequent packets through the queue, however, after
7989 the first packet is put to queue then any subsequent packets
7990 must also be put to the queue.
7992 Follow these rules and everything works fine.
7994 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * Added new function silc_server_remove_clients_by_server to
7997 remove all client entries from ID list when the server connection
7998 is lost. In this case it is also important to invalidate all
7999 client entires as they hold the invalid server entry. This
8000 fixes fatal bug when server has lost connection and will reconnect
8003 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8005 * Made some sanity checks to silc_server_daemonise like to check
8006 whether the requested user and group actually exists.
8008 * Added sanity check to SKE's silc_ske_responder_finish to check
8009 that the public and private key actually is valid.
8011 * Invalidate the client's nickname when receiving Replace ID
8012 packet and the Client ID is being replaced. This means that the
8013 server will query the nickname if someone needs it (client)
8016 * Sort the ID Cache in client library when the ID Cache data
8017 has changed (needs sorting).
8019 * Do not allow for SILC client to create several connections to
8020 several servers. The client does not support windows right now
8021 and generating multiple connections causes weird behaviour.
8023 Irssi-silc client does support windows and can handle several
8024 connections without problems, see: www.irssi.org and SILC plugin.
8026 * Fixed some places where client was added to the IDList. The
8027 rule of thumb is following (in order to get everything right):
8028 If the client is directly connected local client then the
8029 `connection' argument must be set and `router' argument must be
8030 NULL to silc_idlist_add_client function. If the client is not
8031 directly connected client then the `router' argument must
8032 bet set and the `connection' argument must be NULL to the
8033 silc_idlist_add_client function.
8035 * The funtion silc_server_packet_send_local_channel actually did
8036 not check whether the client was locally connected or not. It
8037 does that now. Fixed a bug related to LEAVE command.
8039 * Fixed Remove Channel User payload parsing bug in server's
8040 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8042 * The server's silc_server_save_channel_key now checks also the
8043 global ID list for the channel as it might not be in the local
8044 list. Fixed a bug related to LEAVE command.
8046 * Is this the end of the [<unknown>] buglet that has been lurking
8047 around for a long time? A little for loop fix in server's
8048 silc_server_command_whois_parse that is used by both IDENTIFY
8049 and WHOIS command. At least, this was a clear bug and a cause
8050 of one type of [<unknown>] buglet.
8052 * WHOIS and IDENTIFY commands call the function
8053 silc_server_command_[whois/identify]_check function even if
8054 we are not router server.
8056 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * Added --with-gmp configuration option. If set the GMP
8059 is always compiled in the SILC source tree. If not set then
8060 it is checked whether the system has the GMP3 installed. If
8061 it has then the GMP won't be compiled (the system's headers
8062 and library is used), if it doesn't have it then the GMP is
8063 compiled in the SILC source tree.
8065 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Changed RSA private exponent generation to what PKCS #1
8068 suggests. We try to find the smallest possible d by doing
8069 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8070 not security fix but optimization.
8072 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8074 * Added new config entry [Identity] to fork the server and run
8075 it as specific user and group. A patch from Bostik.
8077 * Imported Dotconf configuration library into lib/dotconf.
8078 This will be used to create the SILC configuration files later.
8079 It will appear in the distsribution after this commit.
8081 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8083 * A big code auditing weekend happening. Auditing code for
8084 obvious mistakes, bugs and errors. Also, removing any code
8087 Removed files for being obsolete:
8089 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8090 inline in the file lib/silcutil/silcbuffer.h)
8092 o lib/silcutil/silcbufutil.c (the header has inline versions)
8094 Changed code to fix possible error conditions:
8096 o The buffer formatting routines now check that the destination
8097 buffer really has enough space to add the data. This applies for
8098 both buffer formatting and unformatting
8099 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8100 unformatting was changed to accomodate following rules:
8101 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8102 sent to the function while XXX_*STRING will not allocate or copy
8103 the data into the buffer. Instead it sets the pointer from the
8104 buffer into the pointer sent as argument (XXX_*STRING used to
8105 require that the pointer must be allocated already). This change
8106 makes this whole thing a bit more consistent and more optimized
8107 (note that the data returned in the unformatting with XXX_*STRING
8108 must not be freed now). The routines return now -1 on error.
8110 o Tried to find all code that use buffer_format and buffer_unformat
8111 and added return value checking to prevent formatting and
8112 especially unformatting errors and possible subsequent fatal
8115 o Changed ske->x and ske->KEY to mallocated pointers in
8116 lib/silcske/silcske.h. Fixed possible data and memory leak.
8118 o Added return value checking to all *_parse* functions. Fixed
8119 many memory leaks as well.
8121 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8122 so that buffer overflows would not happen. All code now also
8123 checks the return value as it can fail.
8125 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8127 * Added reconnection support to server if the normal server looses
8128 its connection to the router (for example if router is rebooted).
8129 The server performs normal reconnection strategy implemented
8130 to the server. Affected file silcd/server.c.
8132 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8134 * Added new packet type SILC_PACKET_SET_MODE that is used to
8135 distribute the information about changed modes (for clients,
8136 channels and clients channel modes) to all routers in the
8137 network. Updated the protocol specification accordingly.
8139 Added functions into silcd/packet_send.c and
8140 silcd/packet_receive.c: silc_server_send_set_mode,
8141 silc_server_set_mode.
8143 Added new files silcmode.[ch] into lib/silccore that implements
8144 the encoding and decoding of Set Mode Payload. Added new type
8145 SilcSetModePayload. Moved the definitions of different modes
8146 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8148 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Oops, a little mistake in server's connection authentication
8151 protocol. The protocol is not ended with FAILURE but with
8152 SUCCESS if the authentication is Ok. :) Affected file is
8155 * Implemented NICK_CHANGE notify handling in server in the file
8156 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8157 the local clients on the channel. After the changing nickname
8158 in router environment snhould work and the [<unknown>] nickname
8159 should appear no more.
8161 The silc_server_replace_id function that receives the Replace ID
8162 payload now sends the NICK_CHANGE notify type also in the file
8163 silcd/packet_receive.c
8165 * Changed WHOIS and IDENTIFY command to support the maximum amount
8166 of arguments defined in protocol specs (3328 arguments). This
8167 fixed a bug that caused problems when there were more than three
8170 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Added extra parameter, command identifier, to the
8173 silc_client_send_command so that explicit command identifier
8176 Changed that ID list routines uses specific command identifier
8177 when sending WHOIS/IDENTIFY requests to the server so that they
8178 can be identified when the reply comes back.
8180 Affected files lib/silcclient/command.[ch],
8181 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8183 * Added `sender' argument to silc_server_packet_send_to_channel
8184 to indicaet the sender who originally sent the packet to us
8185 that we are now re-sending. Ignored if NULL. Affected file
8186 silcd/packet_send.[ch].
8188 * Added some server statistics support in silcd/server_internal.h
8189 SilcServerStatistics structure and around the server code. Also
8190 send some nice statistics information when client is connecting
8193 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8195 * Fixed channel ID decoding in server's JOIN command reply in
8196 silcd/command_reply.c
8198 * Fixed braodcasting of replace ID payload to not to send it if
8199 we are standalone server in silcd/packet_receive.c.
8201 * Fixed all channel message sending routines to not to send
8202 packets to clients that has router set, since they are routed
8203 separately in the same function earlier. Affects file
8204 silcd/packet_send.c and all channel packet sending functions.
8206 * In USERS reply, res_argv[i] are not allocated, the table
8207 is allocated. Thus changed that free the table, not its
8210 * In server's whois_check and identify_check if the client is
8211 locally connected do not send any WHOIS commands - they are not
8214 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Fixed some minor bugs in client when sending WHOIS command. The
8217 arguments was in wrong order.
8219 * Removed statis function add_to_channel from server in
8220 silcd/command.c that was previously used with the joining but
8223 * Tested USERS command in router environment successfully with two
8224 routers, two servers and two clients.
8226 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8228 * Reorganized the USERS command and command reply in client library
8229 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8230 When the command is given by user we register a pending command
8231 callback that will reprocess the command after the reply has been
8232 received from the server. When reprocessing the packet we then
8233 display the information. Thus, the USERS information is displayed
8234 now in the command callback instead of in the command reply
8235 callback. The processing of the command is same as previously
8236 when server has sent the command reply in the JOINing process.
8238 * Added to USERS command in silcd/command_reply.c to join the client,
8239 we didn't use to know about, to the channel after we've created
8240 a client entry for it. Also, for clienet we did know already still
8241 check whether it is on the channel or not and add it if not.
8243 * Removed silc_server_command_join_notify as the function and its
8246 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Changed the client's pending command handling to the same as the
8249 server's pending command handling. It is also now possible to
8250 execute command reply functions from other command reply
8251 function as the function callbacks for commands and command
8252 replies are one and same. The pending commands are not static
8253 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8254 in client connection context. Thus, pending commands are server
8255 connection specific as it is convenient.
8257 Changed the function silc_client_command_pending and
8258 silc_client_command_pending_del and added new function
8259 silc_client_command_pending_check. Removed the
8260 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8263 * Added cmd_ident, current command identifier, to the client
8264 connection context in lib/silcclient/client.h to keep track on
8265 command identifiers used in command sending. Client's command reply
8266 function handling now supports the mandatory command identifiers.
8268 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8269 funtions in client to fully support pending command callbacks.
8271 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8272 as one of the arguments to the application in the command reply
8275 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8276 before first releasing SILC but came back. Now it is removed again
8277 and should come back nomore. The FORWARDED flag was used only
8278 by the JOINing procedure by forwarding the command packet to router.
8279 Now, the JOINing procedure has been changed to more generic (due
8280 to various router environment issues) and FORWARDED is not needed
8281 anymore for anything. The protocol specification is yet to be
8284 Now, removed silc_server_packet_forward from server and the flag
8285 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8287 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Renamed NAMES command to USERS command. The NAMES was named that
8290 due to historical reasons. Now it is renamed. Also, rewrote
8291 parts of the USERS command. The nickname list is not sent anymore
8292 by the server. Only Client ID and mode lists are sent in the USERS
8293 command. Changed this also to the protocol specification.
8295 The client now resolves the names and stuff after it receives
8296 the USERS list from the server when joining to the channel.
8298 * WHOIS and IDENTIFY commands has been changed to support multiple
8299 Client ID's per command. One can now search for multiple users
8300 in the network by sending only one WHOIS or IDENTIFY command.
8301 Changed the code and the protocol specifications.
8303 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8304 uses silc_server_command_whois_parse to parse the request. */
8306 * If normal server, do not parse the WHOIS and IDENTIFY requests
8307 before sending it to the router. Saves some time.
8309 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Fixed JOIN command on client library. Wrong number of arguments
8312 used to crash the client.
8314 * Added silc_server_channel_has_global function to check whether
8315 channel has global users or not.
8317 * Added silc_server_channel_has_local function to check whether channel
8318 has locally connected clients on the channel.
8320 * The silc_server_remove_from_one_channel now checks whether the
8321 channel has global users or not after given client was removed from
8322 the channel. It also checks whether the channel has local clients
8323 on the channel anymore. If it does not have then the channel entry
8324 is removed as it is not needed anymore.
8326 * The silc_server_notify now checks on JOIN notify whether the joining
8327 client is one of locally connected or global. If it is global then
8328 the channel has now global users on the channel and that is marked
8329 to the channel entry. Also, it now saves the global client to
8330 global list who is joining and JOINs it to the channel. This is
8331 for normal server, that is.
8333 Changed silc_server_send_notify_on_channel,
8334 silc_server_packet_relay_to_channel and
8335 silc_server_packet_send_to_channel check if we are normal server
8336 and client has router set (ie. global client) do not send the
8337 message to that client, as it is already routed to our router.
8339 * Implemented LEAVE notify type handling in silc_server_notify
8342 * Tested LEAVE command in router environment successfully. Tested
8343 with two routers, two servers and two clients.
8347 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8349 * Implemented SIGNOFF notify type handling in silc_server_notify
8352 * silc_server_remove_id now removes the client entry from all channels
8353 it has joined and thusly sends SIGNOFF notify type.
8355 * Rewrote the NAMES list generation in server by removing two excess
8356 loops. The lists are created now inside one loop.
8358 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8360 * silc_server_remove_channel_user checks now also global list
8361 for channel and client.
8363 * silc_server_new_channel_user checks now both local and global
8364 list for channel and client. Fixed a bug in client id decoding.
8365 Used to decode wrong buffer.
8367 * silc_server_channel_message checks now both local and global
8368 list for channel entry.
8370 * Tested channel joining (hence JOIN) in router environment
8371 successfully. Tested with two routers, two servers and two
8374 * Tested channel message sending in router environment successfully.
8376 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Added silc_server_save_channel_key into server.[ch] to save the
8379 received channel key in Channel Key payload processing. It is
8380 also used in JOIN command reply handling.
8382 Equivalent function silc_client_save_channel_key added into
8383 client.[ch] into client library.
8385 * Changed JOIN command reply to send information whether the channel
8386 was created or not (is existing already) and the channel key
8387 payload. Changed protocol specs accordingly.
8389 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8390 the request was sent by ID and not by nickname. Crashed on
8393 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8395 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8396 now correctly save the received data.
8398 * silc_server_free_sock_user_data now notifies routers in the
8399 network about entities leaving the network.
8401 At the same time implemented functions silc_server_remove_id
8402 and silc_server_send_remove_id to receive and send REMOVE_ID
8403 packets. The packet is used to notify routers in the network
8404 about leaving entities. The ID removed will become invalid in
8407 * Added function silc_idlist_del_server into server. Removes and
8408 free's server entry from ID list.
8410 * silc_server_private_message function now checks, if we are router,
8411 that the destination ID really is valid ID, naturally.
8413 * In router when NEW_ID packet is received (for new client) the
8414 hash of the Client ID is saved in the ID Cache but the
8415 client->nickname is set to NULL, instead of putting the hash
8418 IDENTIFY command now also checks that client->nickname must be
8419 valid. If it is not if will request the data from the server who
8420 owns the client. Added new function
8421 silc_server_command_identify_check.
8423 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8424 to set the command to already allocated Command Payload.
8426 * Tested private message sending in router environment with two
8427 routers, two servers and two clients. Fixed minor bugs and now
8430 * Fixed segfault from client's NAMES command. Used to crash if
8433 * Forwarded packets must not be routed even if it is not destined
8434 to the receiver. Changed server code comply with this.
8436 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8438 * Added `require_reverse_mapping' boolean value to ServerParams
8439 structure. If TRUE (not default) the server will require that
8440 the connecting host has fully qualified domain name.
8442 If the reverse mapping is not required and hostname could not be
8443 found the IP address is used as hostname.
8445 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8447 * Implemented version string checking to both client and server.
8448 The check is incomplete currently due to the abnormal version
8449 strings used in development version of SILC.
8451 * Changed all command functions in server to use the new
8454 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8456 * Changed char *data to unsigned char *data in ID Cache system to
8457 support binary data as ID Cache data. Changed code to support
8458 binary data in lib/silccore/idcache.c.
8460 * Renamed silc_server_packet_relay_command_reply to
8461 silc_server_command_reply as it is normal packet receiving
8462 function. Rewrote the function to accept command replys for
8463 servers and not only for clients.
8465 * Mark remote router always as registered server if we are connecting
8466 to it. Otherwise, commands sent by the router to us are ignored.
8468 * All ID List find routines now returns the ID Cache Entry pointer
8469 as well if requested.
8471 * WHOIS command works now in router environment, tested with two
8472 routers, two servers and two clients.
8474 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8475 in router environment (as it is almost equivalent to WHOIS) but
8476 hasn't been tested thoroughly. Added new functions:
8478 silc_server_command_identify_parse
8479 silc_server_command_identify_send_reply
8480 silc_server_command_identify_from_client
8481 silc_server_command_identify_from_server
8483 * Disabled route cache adding because adding two different ID's with
8484 same IP replaces the old cache entry thus giving wrong route.
8485 The entry->router->connection is always the fastest route anyway
8486 so route cache may not be needed. Of course, new routes maybe
8487 established after receiving the ID when the entry->router->connection
8488 might not be anymore the most optimal.
8490 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8492 * Add route cache for received ID for fast routing.
8494 * Added silc_server_packet_route to route received packet on router
8495 that is not destined to us.
8497 * Renamed silc_server_get_route to silc_server_route_get.
8499 * Added id_string and id_string_len fields into SilcServer to
8500 include encoded ServerID for fast comparing without excess
8501 encoding of the ID's.
8503 * Cleaned up WHOIS command on server side. Added following static
8506 silc_server_command_whois_parse
8507 silc_server_command_whois_check
8508 silc_server_command_whois_send_reply
8509 silc_server_command_whois_from_client
8510 silc_server_command_whois_from_server
8512 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8513 arguments in command replies. All command functions should be
8514 updated to use this macro.
8516 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8518 * Minor typo fixes on command reply handling on server.
8520 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8522 * Added silc_server_command_add_to_channel internal routine to add
8523 the client to the channel after router has created the channel and
8524 sent command reply to the server.
8526 * Added generic silc_server_send_command to send any command from
8529 * Use static buffer with ID rendering instead of duplicating data.
8531 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8533 * Fixed a channel user mode bug when joining to a channel server gave
8534 everybody channel founder rights, oops.
8536 * We mark ourselves as the router of the incoming server connection
8537 if we are router ourselves. This way we can check in some packet
8538 sending functions whether it is locally connected server. For
8539 incoming router connections we put NULL.
8541 * For router sending packets locally means now always sending the
8542 packet cell wide; to local clients and local servers. For normal
8543 server sending packet locally means sending it to only local
8546 * Fixed the JOIN command to really work in router environment. If the
8547 channel is created it is always created by the router. Router is
8548 also responsible of making the initial joining to the channel,
8549 sending JOIN notify to the sending server and distributing
8550 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8551 does not exist server doesn't do anything else but forward the
8552 command to the router which performs everything.
8554 * Added silc_server_send_channel_key function to send the Channel Key
8557 * Added silc_server_create_channel_key to create new channel key. The
8558 channel key is now re-generated everytime someone joins or leaves
8559 a channel, as protocol dictates. Note: channel->key_len is the
8562 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8564 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8565 packet_receive.[ch] to separate packet sending and receiving
8566 routines. The server.[ch] now includes everything else including
8567 actual packet processing (writing and reading data) and other
8570 Renamed silc_server_private_message_send_internal to
8571 silc_server_send_private_message. The routine is still though
8572 used only to relay private messages as server does not send
8573 private messages itself.
8575 Renamed silc_server_new_channel to silc_server_create_new_channel
8576 and added new function sicl_server_new_channel that handles the
8577 incoming New Channel packet. Added also new sending function
8578 silc_server_send_new_channel to send New Channel Payload.
8580 * Added new function silc_server_notify to process incoming notify
8581 packet to the server/router. Server may then relay the notify
8582 to clients if needed.
8584 * Added new function silc_server_new_channel_user to process incoming
8585 New Channel User packet. Router will redistribute the packet and
8586 send JOIN notify to its local clients and locally connected servers
8587 if needed. Normal server will send JOIN notify to its local client
8588 on same channel when received this packet. Added also corresponding
8589 sending function silc_server_send_new_channel_user to sent the
8592 * Added boolean route argument to send_notif_to_channel and
8593 packet_send_to_channel functions to attempt to route the packet
8594 if it is TRUE and send only locally if it is FALSE.
8596 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8598 * silc_server_replace_id now broadcasts the received replace ID
8599 packet if it is not broadcast packet already. The router must
8600 broadcast to inform other routers about changed ID.
8602 * Added backpointer to server's router into SilcServer context in
8603 silcd/server_internal.h.
8605 * Fixed silc_server_packet_broadcast to send correct broadcast
8608 * The channel key is now distributed to the local client as soon
8609 as it is received from the router (in router environment) so that
8610 no other packet may be sent for the channel until client has
8613 * silc_server_remove_channel_user now broadcasts the received
8614 Remove Channel User packet if it is not broadcast packet already.
8615 The router must broadcast to inform other routers about removed
8618 * Added users field into SilcPacketContext that is a reference count
8619 of the context. One can increase the reference count by calling
8620 silc_packet_context_dup which is now changed to just increase the
8621 reference count instead of duplicating the data. The reference
8622 count is decresed by calling silc_packet_context_free that will
8623 free the data after the reference count hits zero.
8625 For now on the packet context and everything allocated into it
8626 (including the raw packet from network) must be freed by calling
8627 the new silc_packet_context_free function. Added also new function
8628 silc_packet_context_alloc that must be used now to allocate the
8629 context. This also means that if a routine is asynchronous from
8630 silc_[client/server]_packet_parse_type the packet context must
8631 be duplicated by calling silc_packet_context_dup. Otherwise it
8632 gets free'd after silc_[client/server]_packet_parse_type returns.
8633 Also, one must remember that if packet is duplicated then its
8634 reference count must be decresed by calling the free function as
8635 many times as it was duplicated.
8637 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8638 from both client and server.
8640 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8642 * Made joining to a channel working in router environment.
8644 * Cleaned up JOIN command on server side and create function
8645 silc_server_command_join_channel internal routine to make the
8648 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8650 * Changed silc_command_pending list to SilcDList. Also, added
8651 `ident' field to SilcServerCommandPending structure to identify
8652 the reply and to call correct callback.
8654 Added silc_server_command_pending_check function to replace the
8655 corresnponding macro. The silc_command_pending list is not
8658 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8659 to set identifier to previously allocated Command Payload. It
8660 is used to set identifier for command when resending Command
8663 * Added silc_command_payload_encode_payload to encode Command
8664 Payload buffer from SilcCommandPayload structure.
8666 * Added silc_argument_payload_encode_payload to encode Argument
8667 payload buffer from SilcArgumentPayload structure.
8669 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8671 * Changed WHOIS command to support router connection on server side.
8672 The whois request is always sent to router unless the server is
8673 standalone server. After server has received the reply from the
8674 router will it send the reply to the client.
8676 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8677 broadcast received broadcast packet. The function is used only
8678 by router. The broadcast packet is always sent to the router's
8681 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8682 render given ID to printable string, for log files for example.
8684 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8686 * Made basic router to router connections working. At least they
8687 can now connect to each other but nothing really works the way
8688 they are supposed - yet.
8690 * Added new initiator token to RouterConnection configuration
8691 file in silcd/serverconfig.[ch]. It is used to tell whether we
8692 are the initiator to the remote router or whether we'll expect
8693 the other end to connect.
8695 * Moved registering of listener task to silc_server_init, hence
8696 the server starts listenning as soon as it is run, even if it
8697 does not have connections to other routers. Let's see how well
8700 * Changed default connection retry timeouts for more suitable in
8703 * Removed cipher and such arguments from silc_idlist_add_client
8704 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8705 Added new function silc_idlist_add_data to add the keys and stuff
8708 * Added SilcIDListData structure and added it to SilcClientEntry
8709 and SilcServerEntry as their first field in the structure. This
8710 way we can explicitly cast the ID entries to the SilcIDListData
8711 structure and get common data for the entries. In past, we had
8712 to first check what type of connection it is and then cast it to
8713 correct ID entry type. Now, we can directly cast the opaque
8714 pointer to the SilcIDListData (no matter what ID entry it actually
8715 is) and get the data needed.
8717 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8720 in some circumstances even if threre were timeout tasks, though not
8721 IO tasks, but tasks anyway. Now fixed.
8723 * Defined SilcServerConnection structure to hold connection specific
8724 stuff about directly connected servers and routers. The definition
8725 is currently in silcd/server_internal.h. I thought about having
8726 a bit more important role fro this struct but for now it is used
8727 only when connecting to other server (or router actually).
8729 * Added connecting retry support in server when connecting to
8730 router(s). The retry feature implement exponential backoff
8731 algorithm. Also, added SilcServerParams structure to hold default
8732 parameters for server. For now, it include these retry settings
8733 and are hard coded. After server is moded to be as Silc Server
8734 Library this structure will be more important.
8736 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8738 * Changed client librarys channel->clients table to SilcList and
8739 changed code accordingly.
8741 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8743 * Changed client's channel table to SilcList and changed code
8744 accordingly. Also changed SilcChannelClientEntry to include back-
8745 pointer to the channel so that client entry can use that structure
8746 as list as well and we have fast cross-reference to the channel.
8747 This change dramatically decreased the complexity of channel
8748 handling with client entry and vice versa (removed one extra
8749 loop when searching for channel entry from many functions).
8751 * Changed server->sim from table to SilcDList and changed code
8754 * NAMES command can now be used from user interface. It will show
8755 the user list on the channel, neatly.
8757 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8758 Code now saves realname of the user if it becomes available.
8760 * Renamed configure.in to configure.in.pre and made ./prepare
8761 script to automatically add correct version string to
8762 configure.in which it creates from configure.in.pre.
8764 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8766 * NAMES command reply now shows users mode with the nickname when
8769 * Moved silc_client_ch[u]mode[_char] functions from
8770 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8771 place sucks, they are utility functions and should be in some
8774 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8776 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8779 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8783 * Added TRQ (efficient deque and list library) into lib/trq. This is
8784 a very good list library that is currently used in the SILC. Defined
8785 SilcList API over the library because I didn't like the API very
8786 much. See lib/trq/silclist.h for the API and examples of how to
8787 use the API. Fixed various places in the code to use the new
8788 SilcList API. The SilcList is meant for lists that has a structure
8789 already defined as a list. It is not suitable to add just some
8790 context to the list (in TRQ, the context is the list actually).
8792 So, I defined SilcDList that can be used for the purpose where
8793 predefined list structure does not exit. This can be used as
8794 such list. Now some context just can be added to the SilcDList.
8795 Currently this list is not used in the SILC just yet, though there
8796 are a lot places where this can replace dynamically allocated
8797 tables and I will fix these places, later, to use SilcDList.
8798 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8799 and use TRQ internally).
8801 Also fixed some annoying warning messages that the original TRQ
8802 code generated. Also minor changes to TRQ's Makefile.in.
8804 * Added support for querying by Client ID to both WHOIS and
8805 IDENTIFY commands into server, as required by the protocol.
8807 * Removed method function pointers from SilcBuffer structure. They
8808 weren't used to anything and just increased the context size for
8809 no good reason. This change also made silc_buffer_alloc and
8810 silc_buffer_free functions inline functions.
8812 * Disabled command flooding detection support until it's fixed so
8813 that it accepts commands in but does not execute them more than once
8816 * Added silc_net_localhost(), to return local hostname, into
8817 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8818 that must be initialized before calling silc_client_init.
8820 * Added new function: silc_server_send_notify_on_channels to send
8821 notify messages to all channels client has joined. It is assured
8822 that the message is sent only once per client.
8824 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8825 lib/silcutil/silcutil.[ch] as silc_format function. The new
8826 function is generic and is used by server as well, not only by
8827 the logging routines.
8829 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8830 the provided version string was not acceptable. Added new function:
8831 silc_ske_check_version into lib/silcske/silcske.h. The function
8832 must be implemented by the application (client or server) and it
8833 does not reside in the SKE library. The function checks the version
8834 string remote end sent.
8836 * Added back pointers (to opaque context and to SilcSocketConnection)
8837 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8839 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8840 duplicate packet context structure.
8842 * Changed `notify' client operation to send same arguments as client
8843 receives from server except for ID's. ID's are mapped to correct
8844 ID entry and that is returned. Also, if channel entry is not sent
8845 by server but the notify is for channel the channel entry is sent
8846 to application (otherwise application doesn't know that it is for
8847 channel (library gets it from packet's Destination ID)).
8849 * Added silc_client_remove_from_channels into client library to
8850 remove a client from all channels it has joined to. Used when
8851 received SIGNOFF notify from server. Added also new function
8852 silc_client_replace_from_channels to replace old ID entry with
8853 new ID entry on all channels. Used when received NICK_CHANGE
8856 * Fixed ID Cache list handling in silc_idlist_get_client in
8857 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8858 to get (or query) client by ID.
8860 * Updated TODO list.
8862 * Added connection authentication status message defined by the
8863 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8864 support for these into the code in client and server side.
8866 * Added generic function silc_client_send_command to send any command
8867 with variable argument list. Application should use this function
8868 to send commands if the command functions provided by the library
8869 does not suite for the application's user interface needs.
8871 * Added new `failure' client operation. Application is notified about
8872 received failure packet if client is executing a protocol. In this
8873 case the protocol's execution has failed.
8875 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8876 is required by the protocol.
8878 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8879 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8882 * Added status flag to SilcSKE object to indicate realtime status
8883 of the SKE protocol.
8885 * Application receives now exactly same command reply arguments as
8886 the library receives from server. However, if ID is received the
8887 corresponding ID entry is returned to the application (eg. Client
8888 ID is mapped to correct SilcClientEntry entry and that is returned).
8889 Changed command_reply client operation due to this change.
8891 * Changed all ID's in commands and in command replys as ID Payloads.
8892 Change affected both client and server side codes.
8894 All ID's sent in SILC network (with execption of ID's in SILC
8895 Packet header) are sent in ID Payload to support variable length
8898 * Server now notifies nick changes and notifies all clients on
8899 the channels about the new nickname (about the new Client ID,
8902 * Implemented CMODE command to change channel modes. Supports all
8903 channel modes defined by the protocol specs except ban and invite
8904 lists. (Also, private channel key mode is supported but support for
8905 setting private channel key in client is missing, thus, this mode
8906 has no effect on client side (except that server requires that the
8907 client uses private channel key and normal channel traffic does not
8910 Also, invite mode works per se, but INVITE command does not work
8911 yet correctly, so you can set channel as invite only channel but
8912 inviting clients to the channel does not work (it is yet to be
8913 thought what's the best way to do it).
8915 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8916 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8917 Implemented CUMODE command to change user's mode on the channel.
8918 Supports all modes defined by the protocol specs.
8920 * Added NAMES command reply to return users modes on the channel.
8922 * Removed unnecessary and slow ciphers from lib/silccrypt.
8924 * Set SO_KEEPALIVE option to connection sockets by default.
8926 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8928 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8929 redefined the Notify Payload into protocol specs.
8931 * Added silc_id_payload_parse_id to get ID directly from raw
8934 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8936 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8937 accept searching by Client ID as well.
8939 * Added support for LEAVE and SIGNOFF notify types in client library.
8941 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8942 to parse ID Payload from raw data.
8944 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8946 * Added flags parameter into silc_ske_assemble_security_properties
8947 function in lib/silcske/silcske.[ch].
8949 * Changed notify client operation to fit better for notify messages
8950 sent by server. The notify payload received from server is now
8951 passed to the application (after parsing it to SilcNotifyPayload).
8952 It is application's responsibility to retrieve the arguments
8953 from the payload and show the message the way it wants. The message
8954 sent by server is implementation specific.
8956 * Changed public keys to comply with the protocol specification.
8957 Old public keys are not supported anymore and are not compatible.
8959 * Removed nickname from Channel Payload as the latest draft removed
8960 it. The client must resolve the nickname from the NAMES command
8961 reply received when it joined the channel.
8963 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8965 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8967 * Fixed some errors in protocol specification drafts.
8969 * Created lib/silccore/silcnotify.c to implement Notify Payload
8970 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8971 generic payloads described by protocol specifications. The file
8972 includes implementations for ID Payload and Argument Payload.
8974 * Changed Command Payload implementation to use the new Argument
8975 Payload. Changed command_xxxx_payload to command_payload_xxxx
8976 to comply with SILC coding conventions.
8978 * Added suppport for Argument Payload handling in Notify Payload
8979 implementation as protocol requires it. Added the new support
8980 into server and client lib as well.
8982 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8984 * Added support for multiple nicknames on same channel. [n] is
8985 added locally to the nickname if there are more than one same
8986 nicknames on the channel.
8988 * Server now sends all nicknames that matched WHOIS request.
8989 Client also shows the list received from server.
8991 * Added TOPIC command to client side. User can now set and show
8992 current topic on channel.
8994 * Added MOTD command to client and server. Also, server sends the
8995 motd when client connects to the server.
8997 * Changed version strings to comply ISO 8601.
8999 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9001 * Fixed protocol error handling in client library. It should now
9002 cope even if the SKE fails for some reason.
9004 * Made new protocol specification drafts for submitting to IETF.
9006 * Implemented TOPIC command to server in silcd/command.c.
9008 * Added two new notify types into lib/silccore/silcnotify.h:
9009 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9010 notify nickname change and topic setting/change on a channel.
9012 * API change of command_reply operation in client library. The
9013 application gets now the status type received from server as well.
9015 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9017 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9019 * Cras fixed and optimized the packet handling even further and
9020 it should work now. Minor change to the prototype of function
9021 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9023 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9025 * Added new function into lib/silcutil/silcschedule.[ch]:
9026 silc_schedule_with_fd to select() a specified fd. The function
9027 returns after timeout expires or data arrives or goes. The
9028 function is used by packet routines to wait that all data is
9029 received from network.
9031 * Fixed data reading from network in lib/silccore/silcpacket.c.
9032 The code now assures that all data is read from the fd and then
9033 continues packet processing. This was a bug fix since the code
9034 used to drop some data in some circumstances.
9036 * Added new function into lib/silcclient/client.[ch]:
9037 silc_client_start_key_exchange to start key exchange after
9038 connection has been established to server. The code internally
9039 now uses this funtion but its main purpose was to provide it
9040 for applications that perform their own connecting. After
9041 application has created a connection it merely calls this
9042 function to start the key exchange between client and server.
9043 The library takes care of everything else after that.
9045 Updated also lib/silcclient/README to explain the usage of
9048 * Do not send to application information that connection has
9049 been established. Application gets notified it by connect
9052 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9054 * Applied cras's patch to add silc_schedule_one function. The
9055 function runs scheduler once and returns.
9057 * Fixed the scheduler after cras messed it up. The timeout
9058 handling works now as it's supposed to work.
9060 * Added into lib/silccore/ silcnotify.h to include notify
9061 message types support. Changed silc_server_send_notify*
9062 functions, in server.[ch], to support those new notify types.
9063 Added the support for the notify types into client library,
9064 as well. Added new notify client operation into ops.h in
9067 * Changed silc_server_packet_send_to_channel to send normal
9068 packets instead of just channel message packets. The function
9069 is now used to send the notify packets to channels. It is not
9070 used to send channel message packets anymore, as server never
9073 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9074 va_arg()s as it seems to require it nowadays. I guess, if SILC
9075 is compiled with older va_arg() the new code should work anyway.
9077 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9079 * Splitted core library. Core library (lib/silccore) includes
9080 now only SILC protocol specific core (and common) components.
9081 Created new utility library (lib/silcutil) that includes more
9082 generic purpose stuff. The stuff for util library was taken
9083 from the old core library. This was minor and easy split.
9085 * Created SILC Client Library (lib/silcclient) that includes
9086 implementation of the SILC client without user interface. This
9087 was major move from silc/ directory. The code has been changed
9088 so that it is transparent towards the user interface. The
9089 silc/ directory includes now the same user interface as before
9090 and it uses the new client library. Read lib/silcclient/README.
9091 Basicly, the client library performs everything else related
9092 to SILC except user interface handling. Also, configuration
9093 files are considered to be part of user interface and library
9094 does not handle them.
9096 This change also changed a lot of structures, function naming etc.
9097 Most important change was that SilcClientWindow object was
9098 renamed to SilcClientConnection in the client library. Created
9099 also new file lib/silcclient/ops.h. Also added new files
9100 silc/local_command.[ch] and silc/client_ops.[ch].
9102 All these changes were made to make it easier for user interface
9103 designers to create what ever user interface for the SILC client
9106 It is also expected that the server will be moved to lib
9107 directory as well and SILC Server Library will be created;
9108 sometimes in the future.
9110 * Removed Local commands from lib/silccore/silccommand.h as
9111 they are application specific and new client library does not
9112 handle any of those anymore.
9114 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9115 old client implementation in silc/.
9117 * Added support for callback functions in SILC_LOG_* macros.
9118 Application can now set its own callbacks that will be called
9119 instead of using the default functions that will always print
9120 the debug messages to stderr (or stdout). Also, debugging can
9121 now be disabled by setting silc_debug to FALSE and re-enabled by
9122 setting it to TRUE. Note, that logging will still work even
9123 if debugging is disabled.
9125 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9126 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9127 silc_log_reset_debug_callbacks.
9129 * To enable debugging in silc client one must give now -d
9130 option on command line.
9132 * Changed silc_schedule_init to automatically allocate task queues
9133 if they are not allocated before calling it.
9135 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9137 * Added GMP 3.1 into math library.
9139 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9141 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9142 a channel in SILC network. The packet is used by servers and
9143 routers to notify other routers that user has left a channel.
9144 This little feature was missing until now. Added the feature
9145 to protocol specification as well.
9147 Added functions: silc_server_send_remove_channel_user and
9148 silc_server_remove_channel_user into server.[ch].
9150 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9151 lib/silccore/silcpacket.h. However, they are not implemented
9154 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9156 * Fixed joining to a channel and sending channel messages
9157 between server and router. The channel message sending should
9158 now work inside a cell.
9160 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9162 * Fixed the private message sending between server and router.
9163 The private message sending should now work inside a cell.
9165 * Added silc_server_replace_id into server.[ch] to replace
9166 existing ID in the SILC network.
9168 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9169 and silc_idlist_replace_server_id into idlist.[ch] in server.
9171 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9173 * Fixed the server to server connections. Server can again now
9174 connect to router. Router to router connections probably does
9177 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9179 * Added dynamic protocol registering support. Now protocols can
9180 registered and unregistered on the fly. Patch by cras.
9182 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9184 * Added lib/contrib directory to hold routines that some platforms
9185 don't have but are needed by SILC.
9187 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9188 into lin/contrib to provide getopt() and getopt_long() for
9189 those who don't have it.
9191 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9193 * Added AWAY command to client. When away message is set and
9194 client receives a private message packet the client automatically
9195 replies to the sender with the away message.
9197 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9198 bug seemed to be the cause of recent problems when compiling
9201 * Added version detection support to SKE protocol specification
9202 and added the new changes to the SKE implementation as well.
9203 There were other minor changes in the SKE protocol as well.
9205 Many changes in lib/silcske/silcske.[ch] and in
9206 lib/silcske/payload.[ch].
9208 * Added ^U functionality, clear input line. Patch from cras.
9210 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9212 * Mainly small bugfixes on core library. Fixed some debugging
9213 logging and buffer overflow in silclog.c.
9215 * Updated config.sub and config.guess on the distribution tree.
9217 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9219 * Added command lagging support in server. Client may execute
9220 commands now only once in two seconds.
9222 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9224 * Optimized packet reception. MAC computation and checking is now
9225 also more optimized. A lot previously duplicated code is now
9226 used as generic by both client and server.
9228 * Fixed key pair generation in clientutil.c
9230 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9232 * Added into lib/silccore/silcbufutil.[ch] new function;
9233 silc_buffer_realloc.
9235 * Moved generic packet sending/encryption functions to
9236 lib/silccore/silcpacket.[ch] from client and server. Some
9237 rewriting of the functions.
9239 * Moved all generic packet reception/decryption functions to
9240 lib/silccore/silcpacket.[ch] from client and server. The
9241 packet processing is now much cleaner in both client and server.
9242 These were major changes in both client and server.
9244 * Created many common functions in server to do packet sending.
9245 Previously code were duplicated a lot, this has been removed
9248 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9250 * Rewrote major parts of the ID cache system. Don't know
9251 whether it is better now or not but at least the API is more
9254 * Major rewrite on ID cache stuff on client because of the ID
9255 cache API changes. Added idlist.c to client.
9257 * Also major rewrite on ID cache stuff on server as well.
9258 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9259 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9260 in hand, instead they are all put into the ID cache system now.
9261 All server_idlist_* routines uses ID cache now instead of
9262 traversing its own lists (those lists does not exist anymore).
9263 SilcIDList though still exists. Also, SilcXXXEntry's are
9266 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9268 * Finally made the SKE implementation compliant to the protocol
9269 specification. All mp integers are now binary encoded as
9270 opposed being HEX encoded.
9272 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9275 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9276 functions: silc_[encode/decode]_pem. Also added function
9277 silc_encode_pem_file to PEM encode with newlines ('\n') for
9280 * SILC public keys are now encoded either PEM or binary. Same
9281 option is for private keys as well. By default private keys
9282 are binary encoded and public keys PEM encoded. Silly HEX
9283 encoding were removed.
9285 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9286 function to create fingerprints.
9288 * Fixed a bug in SHA1; does not change the original data anymore.
9290 * Partly implemented INFO command on client and server side.
9291 Fixed CLEAR command. Changes to SERVER command; show current
9292 server(s) when giving command without arguments. Added
9293 VERSION command to client.
9295 * Added check to server that unregistered connections cannot
9296 execute commands (unless it is specificly allowed).
9298 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9300 * Fixed screen refresh.
9302 * Fixed channel joining bug from client. On some circumstances
9303 client tried to join to a channel it had already joined.
9305 * Added public key verification process into client's protocol.c.
9306 The client now verifies the public key from user and saves
9307 it into ~./silc/serverkeys/ directory.
9309 Added into: clientutil.[ch]: silc_client_verify_server_key.
9311 * Changed SKE protocol's silc_ske_initiator_finish function
9312 to accept callback function that verifies the received public
9313 key. Removed old silc_ske_verify_public_key function.
9315 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9317 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9318 silc_pkcs_private_key[_data]_set.
9320 * Made the password and public authentication more cleaner in
9321 server's protocol.c.
9323 * Removed historic and obsolete protocol `channel_auth' from
9324 both client and server.
9326 * Removed wrong way of sending command status messages from
9327 server to client in server's command.c. The old way violated
9328 protocol specification.
9330 Changes to silccore/silccommand.[ch]: removed
9331 silc_command_encode_status_payload -> not needed anymore,
9332 changed silc_command_encode_payload_va to accept extra
9333 argument on variable argument list. The argument type must
9334 now be provided to the function. Also, added new function:
9335 silc_command_encode_reply_payload_va which is same as
9336 normal command_encode_payload_va except command status type
9337 is provided as extra argument.
9339 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9341 * Added ~./silc directory handling. The directory includes the
9342 public and private keys for the client.
9344 Added silc_client_check_silc_dir, silc_client_create_identifier
9345 and silc_client_load_keys.
9347 * Implemented SILC protocol compliant public key. Added public
9348 and private key saving to and loading from files.
9350 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9351 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9352 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9353 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9354 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9356 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9357 silc_pkcs_load_[public/private]_key.
9359 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9361 * Added silc_server_get_route (route.[ch]) to get connection
9362 data for the fastest route for given ID.
9364 * Implemented INVITE command on client and server. The command
9365 were re-defined in the SILC Protocol Specification and the
9366 implementation now complies with the specification.
9368 * Implemented PING command on client and server.
9370 * Implemented NAMES command on client and server. The server side
9371 supports currently only normal server not router server yet.
9372 Some changes to NAMES definition in SILC protocol specification.
9374 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9376 * Implemented LEAVE command on client and server.
9378 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9379 again. This change was made to the protocol as well. Server
9380 should not violate the protocol specification anymore.
9382 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9384 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9385 was tested. SOCKS4 was not but should work anyway.
