1 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Merged c0ffee's MIME signal patch which adds support for
4 sending also MIME messages in Irssi SILC Client, and handling
5 received MIME messages in a signal (and perhaps doing something
6 to non-textual MIME messages).
8 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
10 * Fixed pending command deletion in server and client library
11 to check the whole list instead of breaking after first found.
12 The affected files are silcd/command.[ch] and
13 lib/silcclient/command.[ch].
15 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * Return NO_SUCH_CHANNEL error in USERS for channel that is
18 secret or private, otherwise it's possible to find out
19 whether a secret channel exists or not. Affected file
22 * If CMODE change fails during the mode setting, assure that
23 the old mode mask is set for the channel back. Affected
26 * Fixed passphrase saving on +a channel on normal server
27 after successful JOIN command. Affected file silcd/command.c.
29 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Remove server/router operator privileges in DETACH command,
32 since it's possible to resume to server where these
33 privileges would not be allowed for the client. Affected
36 * Do not set to wait for backup in rehash of the server.
37 Affected file silcd/server.c.
39 * Do not check listener sockets when counting how many
40 socket connections we have. Affected file is
43 * Do not announce disconnected clients that are remaining
44 in history (for WHOWAS). This is because SIGNOFF notify
45 for these has been sent earlier already. Affected file
48 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
50 * Buffer overflow with CUMODE command's mode->mode character
51 conversion. Reported by Ville Räsänen. Affected file
52 lib/silcutil/silcutil.c.
54 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Allow heartbeat packets to go disabled connections anyway.
57 Affected files silcd/server.c and silcd/packet_send.c.
59 * Do not broadcast New Channel packets with List flag set
60 in the packet to backup routers. The router must check
61 for the correctness of the packets before sending them.
62 It is possible that router will have enforce Channel ID
63 change and this would cause desync in the backup router.
64 Affected file silcd/packet_receive.c.
66 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
67 are handled in list parsing. They are not list packets
68 anymore. Affected file silcd/packet_receive.c.
70 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
72 * Stop waiting for backup router through the timeout, not
73 directly after backup router has arrived. Affected file
76 * Do not re-create channel keys and send them when removing
77 clients in server shutdown. Affected files are
78 silcd/server_internal.h and silcd/server_util.c.
80 * Notify distribution to backup routers was missing from
81 the silc_server_send_notify_dest function which caused
82 desyncing problems with backup router. Affected file is
85 * The client's channel removing was working wrong on
86 backup router. It assumed that it doesn't know global
87 information but backup router does know. For this reason
88 it could remove channel when it wasn't supposed to do that.
89 Affected file silcd/server.c and silcd/server_util.c.
91 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
93 * Stop for a couple seconds after badkup router has become
94 primary router. Affected file silcd/server.c.
96 * Added silc_server_remove_servers_by_server, which is used
97 to remove servers originated from some other server. Also
98 clients of those servers can be removed too. Affected file
99 silcd/server_util.[ch].
101 * When removing clients after a server has signed of remove
102 also all servers behind that server (unless they are known
103 to be available locally), and send SERVER_SIGNOFF for each
104 of the server separately. Also the signed off clients are
105 sent now separately per signed off server. The affected files
106 are silcd/server.c and silcd/server_util.[ch].
108 * All servers added with silc_idlist_add_server must always
109 have both "router" and "connection" pointers set. Otherwise,
110 bad server entries may be left around in the cache.
111 Affected file silcd/command_reply.c.
113 * Do not create the channel key in NEW_CHANNEL packet
114 processing if the channel is empty. Affected file
115 silcd/packet_receive.c.
117 * Completed backup router support for standalone routers.
118 Supports also servers in the cell that do not use the backup
121 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
123 * Fixed a bug in silc_string_regexify which did not add '^'
124 at the start of each string, and thus the matching was
125 not explicit. For example ban list iikone@*!*@* would
126 match also "priikone", which is wrong, it would have to be
127 *iikone@*!*@* to match also "priikone". Affected
128 file lib/silcutil/unix/silcunixutil.c.
130 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
132 * Enable all local server connections before updating client
133 caches when we've become backup router. Otherwise, signoff
134 packets may not reach the clients. Affected files are
135 silcd/server.c and silcd/server_util.[ch].
137 * Fixed a bug in version string parsing which could crash
138 the program with specially formatted version string.
139 Bug reported and patch provided by Ville Räsänen. Affected
140 file lib/silcutil/silcutil.c.
142 * Handle the disconnection immediately when DISCONNECT
143 packet is received in server. Affected file silcd/server.c.
145 * Primary router now waits a short time (10 seconds) for
146 backup router connection before accepting any other
147 connection (except local). Affected file silcd/server.c,
150 * Fixed a crash in client libary in NICK_CHANGE notify when
151 NICK_CHANGE arrived for client entry we are resolving
152 currently. Affected file lib/silcclient/client_notify.c.
154 * Call the sconn->callback completion even if error had
155 occurred. Start reconnecting always if connection to
156 primary router fails during backup router protocol.
157 Affected files silcd/server.c and server_backup.c.
159 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
161 * Added functions silc_server_send_opers and
162 silc_server_send_opers_notify to send packets stricly
163 to operators. Added macro SILC_SERVER_SEND_OPERS macro
164 to send variable argument notify to operators.
165 Affected files silcd/packet_send.[ch] and silcd/server.h.
167 * Removed UMODE rights checking with UMODE_CHANGE notify.
168 Affected file silcd/packet_receive.c.
170 * Server/router operator now receives notify when network
171 switches to backup router and when it resumes the use of
172 primary router. Affected file silcd/server.c and
173 silcd/server_backup.c.
175 * Fixed the updating of client information after backup
176 resuming protocol is over; update all except local clients
177 to the new primary router. The affected file is
180 * Added support for closing active connections in rehash
181 that were unconfigured by the user. Supports currently
182 closing server and router connections. Affected file
185 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
187 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
189 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
190 is NULL since seems that on some platforms NULL is allowed
191 and on some it's not. Fallback encoding is used instead.
192 Affected file lib/silcutil/silcstrutil.c.
194 * Fixed statistics updating for incoming server connection
195 which could cause problems when re-connecting. Affected
198 * Preliminary backup router support for standalone router
199 added. Affected files in silcd/.
201 * Mark server connections in backup router disabled before
202 and after backup protocol. Affected file is
203 silcd/server_backup.c.
205 * Added support for reconnecting to remote server connection
206 even if the protocol fails, and if the configuration wants
207 us to keep trying to connect anyway.
209 Server connection is not allowed to backup router if
210 backup router does not have connection to primary router yet.
212 Affected file is silcd/server.c.
214 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Added silc_client_udpate_server function to update changed
217 server info. Affected file lib/silcclient/idlist.[ch].
219 * Added check for server entries that are being resolved when
220 notify is received. If being resolved, handle the received
221 notify only after it's resolved so that all notifys are
222 handled in same order as received from the server.
224 Added similar resolver check to channel entries. Every
225 notify that cause resolving of any information that affects
226 channel entry marks the channel entry in waiting state.
227 After whatever resolving is over the waiters are signalled
228 and only then the notifys are handled in the same order
229 as delivered from the server.
231 Affected files are lib/silcclient/idlist.[ch], and
234 * Fixed KILLED notify handling in normal server. Affected
235 file silcd/packet_receive.c.
237 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
238 is locally connected, or was locally connected (but may
239 be detached and connection is not active). Added also
240 SILC_IS_LOCAL for checking this status. Affected files
241 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
242 silcd/server.c and silcd/server_internal.h.
244 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
246 * Don't send or handle TOPIC_SET if topic is already set and
247 is same as being set. Affected files silcd/command.c and
248 silcd/packet_receive.c.
250 * Fixed CMODE change rights checking to work correctly when
251 removing modes by operator. Affected file is
254 * Fixed some handling with New Channel packet in router and
255 fixed some CMODE_CHANGE notify handling in server and router.
256 Affected file is silcd/packet_receive.c.
258 * Changed "disconnect" client operation to include the
259 reason of the disconnection and optional disconnection
260 message. Affected file lib/silcclient/silcclient.h.
262 * Made the compilation of lib/contrib/ stuff conditional.
263 Affected files configure.in.pre, lib/contrib/Makefile.am.
265 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
267 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
268 to the sender of the notify too, to avoid situation where two
269 notifys are in the network at the same time going to oppsite
270 directions. Affected file silcd/packet_receice.c.
272 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
274 * Delete the client from channel even if the cilent->id is
275 NULL. It was possible that client was deleted without
276 removing from channels (theoretically at least). Affected
277 file silcd/server.c and silcd/server_util.c.
279 * Free the client data too when resuming is not successful.
280 Affected file silcd/packet_receive.c.
282 * Merged some code from c0ffee's silc-plugin. Affected files
283 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
285 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
286 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
287 to the primary router connection, the other one returns
288 TRUE if packet must be broadcasted to network.
290 * All notifys that are destined to primary router (to network)
291 are now automatically sent to backup routers even if the
292 router is standalone (and has backup router). Affected files
295 * Added --without-irssi and --without-silcd configuration
296 options for disabling the compilation of these applications.
297 Affected file configure.in.pre and prepare.
299 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
301 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
302 UTF-8 encoding and decoding. Added also new encodings
303 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
305 Added also SILC_STRING_LANGUAGE which is language and charset
306 specific encoder and decoer for those platforms that support
307 iconv(). It can convert the UTF-8 to and from the locale
308 specific character set.
310 Affected file lib/silcutil/silcstrutil.[ch].
312 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
314 * Added function silc_get_command_name to the file
315 lib/silcutil/silcutil.[ch].
317 * Improved the server debug output a bit. Affected files are
320 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
322 * Save the channel passphrase when received succesful JOIN
323 command reply from router, on normal server. Otherwise
324 joinig +a channels from normal server is not possible.
325 Affected file silcd/command.c.
327 * Fixed a bug in TOPIC_SET notify handling. The notifier
328 may be other than client too, like server or channel.
329 It expected it to always be only client and ignored the
330 notify. Affected file silcd/packet_recieve.c.
332 * Removed some (unnecessary) debug printing from
333 lib/silccore/silcid.c and lib/silccore/silcargument.c.
335 * Do not force CMODE_CHANGE when server is announcing new
338 Router announces stuff only after server reannounces channel
339 after CHANNEL_CHANGE notify.
341 These fixes optimizes the announcing procedure, and perhaps
342 fixes some problems too. Affected file silcd/packet_receive.c.
344 * Fixed SERVER_SIGNOFF sending to local clients. It was
345 totally broken and sent the notify to all local clients,
346 instead of only to those that was on same channel as the
347 signing off clients. Affected file silcd/server_util.c.
349 * Added -D option to server. It can be used to give debug
350 level. The levels are from 0 - 99, and are predefined for
351 smooth server debugging. (see silcd.c for the predefined
352 levels). Affected file silcd/server.c.
354 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
356 * Fixed a bug in Irssi SILC client to close the connection
357 properly when disconnecting from server. Affected file
358 irssi/src/silc/core/client_ops.c.
360 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
362 * When authenticating as founder during JOIN command, check
363 that the one authenticating becomes the only founder on the
364 channel. Affected file silcd/command.c.
366 * Better checking for founder mode setting when CUMODE_CHANGE
367 notify is received. Affected file silcd/packet_receive.c.
369 * Close all connections when shutting down the server by sending
370 DISCONNECT packet. Close all listeners too when shutting
371 down the server. Affected file silcd/server.c.
373 * Handle DISCONNECT packet correctly in client library by
374 calling the "disconnect" client operation. Affected file
375 lib/silcclient/client.c.
377 * Handle local errors correctly during resuming. Affected
378 file lib/silcclient/client.c.
380 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
382 * The log file is not dupped internally anymore in
383 lib/silcutil/silclog.c. Fixed memory leaks too.
385 * The scheduler now dispatches all pending timeout tasks
386 when it is uninitialized with silc_schedule_uninit.
387 Affected file lib/silcutil/silcschedule.c.
389 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Added --enable-stack-trace option to configure. Added
392 memory allocation stack trace support. Added files
393 lib/silcutil/stacktrace.[ch]. Affected files are
394 lib/silcutil/silcmemory.[ch].
396 * Fixed memory leaks from libraries and server. Affected
397 files around the tree.
399 * Reverted back a fix made to CUMODE which broke it.
400 Affected file silcd/command.c.
402 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
404 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
405 core library, and implemented it. All textual messages SHOULD
406 use this flag and the message MUST be UTF-8 encoded.
407 All text messages sent by Irssi SILC client are now UTF-8
408 encoded (regardless whether the terminal supports UTF-8 or not).
409 Affected files are lib/silccore/silcchannel.h,
410 irssi/src/silc/core/silc-servers.c, silc-channels.c and
413 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Added lots of new statistics updating that was missing from
416 the server and router code. Affected files in silcd/.
418 * Sending SIGUSR1 signal to server now dumps the current
419 server statistics into /tmp directory. Affected file is
422 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
423 the SILC Hash Interface also. Added new functions
424 silc_hash_get_name, silc_hash_init, silc_hash_update and
425 silc_hash_final. Affected file lib/silccrypt/silchash.c.
427 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Added some better info printing for client during connecting.
430 Affected file silcd/server_util.c.
432 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
433 to silence a user on a channel. Affected files are
434 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
435 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
436 and silcd/packet_receive.c.
438 * Fixed a fatal bug in handling of malformed command payload.
439 Affected file silcd/command.c.
441 * Fixed a double free when announcing channel users to router.
442 Affected file silcd/server.c.
444 * After successful authentication to channel founder mode, check
445 that there isn't anyone else with founder mode on the channel.
446 The one that authenticated will become founder and anyone
447 else is demoted. Affected file silcd/command.c.
449 * Added error printing of any error that has occurred during
450 any command in client library. Affected file is
451 irssi/src/silc/core/client_ops.c.
453 * Removed some error printing from the client library and left
454 it for the application to worry (from the error status it
455 receives in 'command' client operation. Affected file is
456 lib/silcclient/command.c.
458 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
460 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
461 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
462 Starting key agreement with itself is denied. Affected file
463 is lib/silcclient/client_keyagr.c.
465 * Fixed some error checkings from the SFTP library which caused
466 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
467 and lib/silcsftp/sftp_util.c.
469 * Added new "debug" and "debug_string" settings to Irssi SILC
470 client which can be used to print runtime debugging on the
471 Irssi's screen. Available when compiled with --enable-debug
472 option. Affected file irssi/src/silc/core/silc-core.c.
474 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
476 * Fixed a missing variadic parameter in a function call that
477 caused server crash when a non-allowed connection arrived.
478 Reported by Richard Becker. Affected file silcd/server.c.
480 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
482 * Added WATCH list sending to backup routers from router.
483 The WATCH command is sent by the router to the backup
484 router. Affected file silcd/command.c.
486 * Mark the backup_router flag for RouterConnection entry
487 if the backup router stuff is defined in the config file.
488 Affected file silcd/serverconfig.c.
490 * Fixed some backup data sending around the code to work better
491 if the router is standalone router. Not all places were fixed.
492 Affected file silcd/packet_receive.c, silcd/packet_send.c,
495 * Fixed the router connecting when connecting to multiple
496 routers. It ignored every other router except the first
497 one. Affected file silcd/server.c.
499 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Made the private key generation after expiration optional.
502 If not created after expiration the old key will re-expire
503 at a later time (and thus key pair is not necessary to
504 change). Affected file irssi/src/silc/core/clientutil.c.
506 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
508 * The length arguments in bind() and connect() were wrong
509 and fixed now to used SIZEOF_SOCKADDR in the
510 lib/silcutil/unix/silcunixutil.c.
512 Tue Jun 4 18:36:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Fixed detach timeout handling to use Client ID and not
515 the actual client entry which may be freed in the callback.
516 Affected file silcd/command.c.
518 Thu May 30 15:53:45 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
520 * Merged c0ffee's multiple interface support patch.
521 Affected files in silcd/.
523 Wed May 29 18:08:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Cleanup keys properly. Affected file is
526 irssi/src/silc/core/clientutil.c.
528 Tue May 28 20:11:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
530 * Display the user mode on the status bar. Affected file
531 irssi/src/silc/core/silc-expandos.c.
533 Tue May 28 13:56:26 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
535 * If private message key is not set, but the flag is set in
536 the packet, ignore the packet since it cannot be decrypted.
537 Affected file lib/silcclient/client_prvmsg.c.
539 Thu May 23 12:00:14 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
541 * When resuming client, remove the old client entry from
542 the watcher list too. Affected file silcd/packet_receive.c.
544 * Do not allow normal server to force founder mode away
545 from router if the founder mode is already set. Affected
546 file silcd/packet_receive.c.
548 * Remove the client entry with watch notify types with short
549 timeout, and not directly, so that other notifys can be
550 retrieved too. Affected file lib/silcclient/client_notify.c.
552 * Display notification about data messages that cannot be
553 displayed. Affected files irssi/src/silc/core/client_ops.c,
554 irssi/src/fe-common/silc/module-formats.[ch].
556 Sun May 19 18:59:00 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Fixed the CHANNEL_CHANGE notify handling in client libary
559 to not use freed memory. Affected file is
560 lib/silcclient/client_notify.c.
562 * Fixed CUMODE_CHANGE notify handling in server. Affected
563 file silcd/packet_receive.c.
565 * Fixed USERS command to support empty channels. Affected
566 file silcd/command.c.
568 Sat May 18 11:35:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Allow multiple identical pending commands to be registered
571 in client library. Affected file is lib/silcclient/command.c.
573 * Call the completion for resolving client information only

1082 and in server to use the silc_parse_version_string. Affected
1083 files are lib/silcclient/protocol.c, silcd/protocol.c.
1085 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1086 commands that was missing it, and updated protocol specs and
1087 the server implementation. Protocol TODO #10. The affected
1088 file is silcd/command.c.
1090 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1091 generic reply to a generic request (REQUEST flag), and
1092 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1093 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1094 to define the payload for DATA flag. Added the flags to
1095 the implementation. Protocol TODO #9. Affected file is
1096 lib/silccore/silcchannel.h.
1098 Changed the client library to return the message length
1099 to application as well in the channel_message and private_message
1100 client operations. Affected files are
1101 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1102 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1103 and lib/silcclient/client_ops_example.c.
1105 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1106 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1107 the channel. Updated protocol specs and impelemented this
1108 to client and server. Protocol TODO #6. Affected files are
1109 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1110 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1112 Added new options m and M to CMODE command in Irssi SILC
1113 client to set these modes.
1115 * Deprecated all administrative commands from SILC protocol
1116 since they are highly implementation specific commands.
1117 Updated protocol specs. Moved the old commands in
1118 implementations to private range of command types. Affected
1119 files are silcd/command.c, lib/silcclient/command.c and
1120 lib/silcclient/command_reply.c. Protocol TODO #8.
1122 * Fixed a bug in server where sending unknown command crashes
1123 the server. Affected file silcd/command.c.
1125 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Added SILC_PROTOCOLVERSION macro to check protocol version
1128 of a socket connection. The affected file is
1129 lib/silcutil/silcsockconn.h.
1131 * Added better error logging in rekey protocol. Affected file
1134 * Do not check public key types in SKE during rekey. Affected
1135 file lib/silcske/payload.c.
1137 * Fixed the rekey protocol with PFS, which was totally broken.
1138 Affected file silcd/protocol.c.
1140 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Some client implementations quit network by doing first LEAVE
1143 and then immediately SIGNOFF (like Bombyx). We now do check
1144 after a short time after LEAVE notify and check whether the
1145 client is still valid after LEAVE, and if not we remove it from
1146 cache. Affected file is lib/silcclient/client_notify.c.
1148 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1150 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1151 it's good not to have security holes here.
1153 * Fixed a negative refcount situtuation for the config context.
1154 Affected file is silcd/serverconfig.c.
1156 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1158 * ROBOdoc documented lib/silcutil/silcutil.h.
1160 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Optimized even more the SilcPacketContext structure. Now
1163 totally saved 16 bytes of memory per context after optimization.
1164 Affected files are lib/silccore/silcpacket.[ch].
1166 * Made strict checks for valid SILC IDs. Affected file is
1167 lib/silccore/silcid.c.
1169 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1171 * Changed the object argument for silc_cipher_register,
1172 silc_hash_register, silc_hmac_register and silc_pkcs_register
1173 to const. Affected files are lib/silccrypt/silccipher.[ch],
1174 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1176 * Changed the silc_get_username and silc_get_real_name to
1177 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1179 * Fixed the Irssi SILC Client to use the silc_get_username and
1180 silc_get_real_name insted of glib routines since the glib
1181 routines only corrupt stack. Fixes the Irssi SILC to work in
1182 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1184 * Fixed the Irssi to not use g_get_home_dir since it crashes
1185 or returns garbage on cygwin and corrupts stack. Added function
1186 get_home_dir to Irssi routines. Affected files are
1187 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1189 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Made some structure optimizations. SFTP memory FS MemFSEntry
1192 entry structure. Optimized SilcTask structure. Optimized
1193 SilcPacketContext structure.
1195 Affected files lib/silcsftp/sftp_fs_memory.c,
1196 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1198 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * And yet again reverted back the config thing since Johnny
1201 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1204 * Fixed memory leaks from config object. Affected files are
1205 silcd/serverconfig.[ch].
1207 * Added support for adding new connections to the server in rehash.
1208 After rehash they take effect.
1210 Added support for changing the maximum allowed connections in
1211 rehash. The number can grow but going smaller is not supported.
1213 Added function silc_server_num_sockets_by_remote to the
1214 silcd/server_util.[ch].
1216 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1218 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1220 * Added preliminary checking during config parsing for a valid
1221 public/private key and removed further checks in the code.
1222 Affected files are silcd/serverconfig.[ch], server.c.
1224 * Moved functions silc_server_drop() and silc_server_daemonise()
1225 from server.c to silcd.c since they are stricly related to
1226 the application activity.
1228 * Reverted a small part of the automatic ref/unref since
1229 it caused a double unref in some situations. Affected
1230 files are silcd/silcd.[ch], server.c, serverconfig.c.
1232 * Added some .cvsignore files in the lib directory.
1234 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Fixed silc_net_gethostbyaddr to correctly resolve by
1237 address. Affected file lib/silcutil/silcnet.c.
1239 * Fixed the notify relaying to client. The HMAC to be used
1240 with relayed packets ws wrong and caused decryption failure
1241 at the client end. Affected file is silcd/packet_receive.c.
1243 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Created new branch silc_protocol_1_0_branch.
1247 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1249 * Changed the silc_server_config_* routines to be SilcServer
1250 independent. They are now officially application specific code
1251 and not part of generic server implementation. Affected files
1252 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1254 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1256 * Added automatic referencing of config context in the
1257 silc_server_config_alloc, and automatic unreferencing in the
1258 silc_server_config_destroy. Affected files are
1259 silcd/serverconfig.[ch], silcd/silcd.c.
1261 * Fixed the silc_log_quick handling in the logging routines.
1262 It didn't log quickly when it was TRUE. Affected file is
1263 lib/silcutil/silclog.c. Also the flush delay was set even
1264 if it was 0 in config file. Affected file is
1265 silcd/serverconfig.c.
1267 * Added support for changing key pair of the server in rehash.
1268 Affected file silcd/server.c.
1270 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1273 too early, before getting the channel entry. Affected file
1274 is silcd/packet_receive.c.
1276 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1278 * Added functions silc_server_config_[ref/unref], these are used
1279 to prevent that the config object is destroyed.
1281 No longer directly affect global variables silc_log_quick and
1282 silc_log_delay, they are first cached inside the config object
1283 and then applied with silc_server_config_setlogfiles().
1285 silc_server_config_set_defaults() is now internal to
1286 serverconfig.c, there are no reasons to show this internal stuff
1289 Affected files are silcd/serverconfig.[ch].
1291 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1292 fprintf's to stderr, since some code may be executed again after
1293 the server went into the background. Affected files are
1296 * Added rehash support. Added function silc_server_rehash() that
1297 will perform all the basic tasks of the rehashing procedure.
1299 * Added command line option `-x, --hexdump'. This will enable the
1300 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1301 The option `--hexdump' implies `--debug'.
1303 * Fixed a bad bug in the logging APIs (silcutil library) where
1304 the application would crash after calling silc_log_reset_all().
1306 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * Fixed the KICKED notify handling in client library to
1309 correctly remove the channel and all entries from the
1310 channel when I was kicked. This bug crashed the client.
1312 Fixed yet another but in KICKED notify handling to remove
1313 the kicked client correctly from the channel.
1315 Affected file is lib/silcclient/client_notify.c.
1317 * Fixed a minor bug in looking up correct client entry
1318 in KICKED notify in server. Affected file is
1319 silcd/packet_receive.c.
1321 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1322 sources correctly to distribution. Fixes --with-gmp option.
1324 * Removed the manual rehashing from ID Cache, and changed it
1325 to use the SILC Hash Table's auto rehash feature. Affected
1326 file is lib/silccore/silcidcache.c.
1328 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1330 * Fixed a bug in the silc_client_nickname_format function that
1331 handles the multiple same nickname formatting. Two clients
1332 with same nickname caused problems after the first one left
1333 and rejoined. It didn't format the nickname correctly.
1334 Affected file is lib/silcclient/idlist.c.
1336 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1338 * Don't change the topic if olod topic is same as new one.
1339 Affected file is silcd/packet_receive.c.
1341 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1343 * Added cross-reference support to the SILC Documentation
1344 generator. All types across all HTML files are now cross-
1345 referenced. Affected files util/robodoc/generator.c and
1346 scripts/silcdoc/silcdoc.
1348 * Added file lib/silcutil/silctypes.h to include all the
1349 arithmetic type definitions and some macros. Removed
1350 includes/bitmove.h and moved macros to silctypes.h.
1352 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1354 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1356 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Added `type' argument to silc_id_payload_parse_id function which
1359 now returns the type of the ID to the sent pointer. Affected
1360 file is lib/silccore/silcid.[ch].
1362 * Added check for CMODE_CHANGE notify type that mode change is
1363 allowed by the sender. Affected file silcd/packet_receive.c.
1365 * Added check for CUMODE_CHANGE notify type that mode change is
1366 allowed by the sender. Affected file silcd/packet_receive.c.
1367 Added the ID type as CUMODE_CHANGE notify type as argument
1368 to the `notify' client operation. Affected files are
1369 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1371 * Added function silc_client_add_server to the client library.
1372 Added support for resolving also channel and server info when
1373 received unknown entity in notify packet. Affected files are
1374 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1376 * Added function silc_command_get_status to return the command
1377 status from the command reply's argument payload. Affected files
1378 are lib/silccore/silccommand.[ch].
1380 * Added check for KICKED notify type that the kicking is
1381 allowed by the client. Affected file silcd/packet_receive.c.
1383 * Created function silc_get_input which can be used to get input
1384 (echo on or off) from user on command line. Affected files are
1385 lib/silcutil/silcutil.[ch].
1387 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Optimized silc_server_packet_relay_to_channel function.
1390 Added new function silc_channel_message_payload_encrypt which
1391 can be called directly if channel message payload needs to
1392 be encrypted and is already encoded (no need to call _encode
1393 function). Packet relaying is now done by router without any
1394 extra memory allocations. Affected files are
1395 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1396 silcd/packet_send.c.
1398 * Fixed the INVITE notify handling. It took wrong arguments
1399 as invite list and invite delete. Affected file is
1400 silcd/packet_receive.c.
1402 * Added check for TOPIC_SET notify type that the topic change is
1403 allowed by the client. Affected file silcd/packet_receive.c.
1405 * Added check for INVITE notify type that inviting is allowed by
1406 the client. Affected file silcd/packet_receive.c.
1408 * Changed the silc_server_client_on_channel to return the
1409 SilcChannelClientEntry as well. Moved the function
1410 silc_server_check_cmode_rights to server_util.[ch].
1411 Affected files are silcd/server_util.[ch], silcd/command.c.
1413 * Added function silc_server_check_umode_rights to check whether
1414 changing client's user mode is allowed. Added check for
1415 UMODE_CHANGE notify type that the umode change is allowed
1416 by the client. Affected files are silcd/server_util.[ch],
1417 silcd/packet_receive.c and silcd/command.c.
1419 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1422 ID length. It ignored that ID can be IPv6 based as well.
1423 Affected file lib/silccore/silcpacket.h.
1425 * Fixed the silc_id_id2str and silc_id_str2id to take the
1426 IPv6 address offset's into consideration. Affecte file is
1427 lib/silccore/silcid.c.
1429 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1431 * Fixed the internal Unix scheduler functions to check for
1432 NULL context they may receive. The affected file is
1433 lib/silcutil/unix/silcunixschedule.c.
1435 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1437 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1438 can specify different directory with --home command line
1439 parameter. Affected files irssi/src/silc/core/client_ops.c,
1442 * SILC-specific commands aren't now executed if the active server
1443 isn't of SILC-type, so there won't be problems with having
1444 IRC and SILC protocol support in same client. Affected files
1445 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1448 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1450 * Improved the signal support in SILC Schedule. Added new
1451 function silc_schedule_signal_call which is used by application
1452 to mark a signal to be called. It is now safe to perform
1453 any kind of tasks in signal callbacks since it is guaranteed
1454 that the application specified signal callback is called
1455 after the signal is over. Affected files are
1456 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1458 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1460 * Added `name' field to SilcChannelPrivateKey to represent
1461 application given name for the key. Moved also the context from
1462 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1463 Added the `name' argument also to the function
1464 silc_client_add_channel_private_key.
1466 Added function silc_client_current_channel_private_key to set the
1467 current channel private key in use.
1469 Added "change" command to KEY command which can be used to change
1470 the current channel private key. Bound the command also to
1471 alt+K (Alt+Shift+k).
1473 Also affected files lib/silcclient/client_channel.c,
1474 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1476 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1478 * Added silc_rng_get_byte_fast function in to the
1479 lib/silccrypt/silcrng.[ch].
1481 * Changed the interface of silc_packet_assemble and the
1482 silc_packet_send_prepare. If silc_packet_assmble is now
1483 called the application does not call silc_packet_send_prepare
1484 because the library will call it automatically. These
1485 interfaces now also return a reference to the outgoing buffer
1486 which includes the assembled packet, which the application can
1487 use to encrypt the packet.
1489 Affected files are lib/silccore/silcpacket.[ch],
1490 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1491 silcd/packet_send.c, server_backup.c and packet_receive.c.
1493 * Fixed a packet sending bug on very high load, where outgoing
1494 packet queue wasn't handled correctly and packets got corrupted.
1495 Affected files are lib/silcutil/*/silc*sockconn.c,
1496 lib/silcclient/client.c and silcd/server.c.
1498 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1500 * Added macro SILC_PACKET_DATALEN which can be used during
1501 packet assembling to check whether the data to be added to
1502 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1503 len is truncated until it fits it.
1505 Added checks for maximum length of channel message payload and
1506 private message payload also.
1508 Added checks for maximum packet length in server and in
1511 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1512 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1513 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1514 lib/silcclient/client_prvmsg.c.
1516 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1518 * Added silc_server_packet_queue_purge call to the
1519 silc_server_disconnect_remote to assure that all data in the
1520 queue before disconnecting is sent to the network. Affected
1521 file silcd/server.c.
1523 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Added the deleting of server's own ID cache entry to the
1526 silc_server_free function. Free also everything else that
1527 has been allocated in silc_server_init. The affected file
1530 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1532 * Added functions silc_parse_version_string, silc_version_to_num,
1533 and silc_ske_parse_version to parse SILC protocol style version
1534 strings. Affected files lib/silcutil/silcutil.[ch] and
1535 lib/silcske/silcske.[ch].
1537 * Added new configuration params: version_protocol, version_software
1538 and version_software_vendor to specify what version the remote
1539 host must at least be to be able to connect to server. The vendor
1540 string can be regex matched too. Added new function
1541 silc_server_connection_allowed to check maximum number of allowed
1542 connections, and allowed versions for incoming connections.
1543 Affected files are silcd/server.c, server_util.[ch] and
1546 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1548 * Added preliminary support for signals in scheduler. The
1549 signals we care about are now blocked always when the scheduler
1550 is locked. This way we can synchronise the use of signal with
1551 scheduler. It is guaranteed that when signal occurs the scheduler
1552 is not locked, and thus new tasks can be safely added to the
1555 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1556 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1557 Added new platform specific routines
1558 silc_schedule_internal_signals_[un]block and
1559 silc_schedule_internal_signal_[un]register.
1561 Added new functions to SILC Schedule API:
1562 silc_schedule_signal_[un]register. Each signal that application
1563 is going to use should be registered to the scheduler.
1565 Affected files are lib/silcutil/silcschedule.[ch],
1566 lib/silcutil/*/silc*schedule.c.
1568 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1570 * Check for unauthenticated client and server in the
1571 silc_server_new_client and silc_server_new_server functions.
1572 Affected file silcd/packet_receive.c.
1574 * Added function silc_string_is_ascii to check whether given
1575 string is 7-bit ASCII string. Affected files are
1576 lib/silcutil/silcutil.[ch].
1578 * Added function silc_id_is_valid_server_id into the
1579 silcd/serverid.c and added checking for valid Server ID's in
1580 silc_server_new_server. The Server ID must always be based
1581 on the server's public IP address.
1583 * Added logging of DISCONNECT packet message in the server.
1584 Affected file silcd/server.c.
1586 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1588 * Changed all library interfaces that use Global RNG to also
1589 accept SilcRng as argument. Affected files are
1590 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1591 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1592 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1593 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1594 lib/silccrypt/rsa.c.
1596 * Added function silc_pkcs_generate_key to the
1597 lib/silccrypt/silcpkcs.[ch] for applications so that they
1598 don't need to do pkcs->pkcs->init calls anymore.
1600 * Remove SilcSocketConnection from the SFTP API since it really
1601 wasn't needed there. The application has the information
1602 saved in its contexts anyway and the SFTP layer doesn't need
1603 know about it. Affected files lib/silcsft/silcsftp.h and
1604 lib/silcsftp/sftp_[server/client].c.
1606 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1610 lib/silcutil/silcutil.c.
1612 * On EPOC the global crypto module lists are not used at all
1613 in the crypto library. Added support for using the constant
1614 algorithm list on EPOC. Affected files are
1615 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1618 * Fixed the handling of third parameter of KICKED notify, since
1619 it was mistakenly updated to SILC Protocol 1.0 even though it
1620 is to be included in 1.1. Since it is not in 1.0 it is not
1621 mandatory, and this fix now handles it only if it is provided,
1622 and it is not error if it is not provided. Affected file
1623 lib/silcclient/client_notify.c.
1625 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1628 client. Affected file irssi/src/silc/core/client_ops.c.
1630 * Merged with Irssi 0.8.4 from irssi.org CVS.
1632 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Check for valid socket connection in client entries before
1635 sending any messages. Fixes a crash, but doesn't fix some
1636 other underlaying bug that is lurking there. Affected
1637 file silcd/packet_send.c.
1639 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1641 * $usermode, $cumode and $cumode_space expandos shouldn't do
1642 anything with non-SILC server records. Affected file
1643 irssi/src/silc/core/silc-expandos.c
1645 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed the silc_net_check_[host/local]_by_sock to support
1648 IPv6 bound sockets as well. Now they can return IPv6 addresses
1649 as well. Affected file lib/silcutil/silcnet.c.
1651 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1652 Affected lib/silcutil/unix/silcunixnet.c.
1654 * Fixed ID rendering (at least on some platforms, not NetBSD)
1655 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1657 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1659 * Added silc_hash_public_key and silc_hash_public_key_compare
1660 functions to be used with SilcHashTable. They can be used to
1661 hash public keys and compare public keys in hash table. Affected
1662 file lib/silcutil/silcutil.[ch].
1664 * Added support for specifying multiple public keys for Client
1665 connection section in server configuration file. This makes it
1666 possible to accept multiple public keys from same host, or to
1667 make a section that accepts any incoming host, and have the
1668 accepted public keys listed in the section.
1670 Added functions silc_sever_[find/get]_public_key, added the
1671 support for this actually to all connection sections but only
1672 the Client section is currently allowed to specify multiple
1675 Affected files are silcd/server.c, server_internal.h,
1676 command.c, protocol.c, server_util.[ch], packet_receive.c.
1678 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1682 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1684 * If silc_debug is TRUE, also output standard logging messages
1685 to stderr with the debug output.
1687 Made silc_log_reset_all() flushing all channels before returning.
1688 Also fixed some documentation typos.
1690 Affected files are lib/silcutil/silclog.[ch].
1692 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1694 * Fixed the server to check correctly the amount of connections
1695 from single host, by checking also the type of the connection.
1696 Fixed also the comparison of number of connections and number
1697 of allowed connections. Affected files are silcd/server.c,
1700 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed the USERS command reply to save the user's mode on the
1703 channel as well. Fixed JOIN command reply to check whether a
1704 client is on channel already and not join it twice. Affected
1705 file lib/silcclient/command_reply.c.
1707 * Added new file silc-expandos.c into irssi/silc/core/ to return
1708 various stuff for various signal for the statusbar etc. updating.
1709 Now Irssi SILC client prints channel user modes etc. on the
1712 * The user mode (like server/router operator changes) is now shown
1713 on the Irssi SILC client's statusbar. The affected files are
1714 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1716 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1718 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1719 to SILC_SCHEDULE_[UN]LOCK macros.
1721 * Added more error printing to logs in server code. Affected
1722 files silcd/server.c and silcd/protocol.c.
1724 * Fixed -S option parsing in Irssi SILC Client. Affected file
1725 irssi/src/silc/core/silc-core.c.
1727 * Added silc_buffer_alloc_size function. Affected file is

1752 * Changed all integer type names:
1753 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1754 to avoid collisions with other libraries using same type names
1757 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Added `prefer_ipv6' argument to the functions
1760 silc_net_gethostbyname[_async]. If it is TRUE it will return
1761 IPv6 address over IPv4. If FALSE IPv4 address is returned
1762 even if IPv6 address was found. Affected files
1763 lib/silcutil/silcnet.[ch].
1765 * Added support silc_net_create_connection[_async] to fallback
1766 to IPv4 address if IPv6 address could not be used (like if

1776 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1778 * Added automatic extern "C" { ... } for C++ compilers so the
1779 application does not need to define them. Affected file
1780 includes/silcincludes.h.
1782 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1783 old name went against naming convention. Applications now
1784 include "silcclient.h" instead of "clientlibincludes.h".
1785 Removed includes/clientlibincludes.h, it is redundant now.
1787 * Renamed includes/version.h to silcversion.h.
1789 * Added really preliminary support for OS/2 into the util
1790 library. Only thread & mutex API is implemented, others
1791 are still to be implemented. Created the lib/silcutil/os2/
1792 directory. Created also file includes/silcos2.h.

1825 * Added `user_count' to the SilcChannelEntry which now tells the
1826 number of users on the channel. The user count is now saved
1827 in normal server of global channels as well. Affected files
1828 silcd/server.c, idlist.h, packet_receive.c and command.c.
1830 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1831 include file utility functions.
1833 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1834 instead of calling directly OS routines.
1836 * Fixed NICK change printing in Irssi SILC Client. Fixed
1837 KICKED notify printing in Irssi SILC Client. Affected file
1838 irssi/src/silc/core/client_ops.c.

1844 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1847 the SKE interface a bit.
1849 * Fixed padding problem in PKCS#1. The padding was not actually
1850 random since the random number generator was used incorrectly.
1851 This security bug affects only when encrypting with PKCS#1, and
1852 it is not currently used at all in SILC. SILC only use signing
1853 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1855 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1913 is now done in silc_core_init() which also fixes autoconnecting
1916 Affected files irssi/src/silc/core/silc-core.c,
1917 irssi/src/fe-text/silc.c.
1919 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1921 * Added new configuration options and blocks:
1922 keepalive_secs, reconnect_count, reconnect_interval,
1923 reconnect_interval_max, reconnect_keep_trying and

1925 implemented the connection parameters when connecting as
1926 initiator and when accepting connections as responder.
1928 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1929 whether given configuration value has been given already.
1931 Affected files silcd/serverconfig.[c], server.[c].
1933 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1934 algorithm parts and created new file silcalgs.conf, that
1935 is now included from the example_silcd.conf.in.
1937 * Optimized the silc_server_connect_to_router_second to take
1938 the connection configuration object from the SilcServerConnection
1939 object instead of finding it during the connecting phase.
1940 Added the configuration object to SilcServerConnection struct.
1941 Affected files silcd/server_internal.h, server.c.
1943 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1945 * Add the client on channel after it was resolved at the
1946 channel message receiving, and it was not already on the
1947 channel. Affected file lib/silcclient/client_channel.c.
1949 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1965 authentication to be set at the same time.
1967 Added `prefer_passphrase_auth' setting in config file which
1968 can be used to set to prefer passwd auth if both passwd and
1969 public key is set. If not set, public key is preferred.
1970 This has effect only when being initiator (responder will try
1973 Added support for authentication with passphrase and public key
1974 at the same time. The passphrase is tried first always since
1975 it is faster to check.
1977 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1979 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2025 * Fixed the file transfer's key agreement payload to include
2026 zero port also if the hostname is NULL because it could not
2029 Call file transfer monitor callback now also if error occurs
2030 during key agreement protocol.
2032 Changed the silc_client_file_send interface to return the
2033 SilcClientFileError instead of session id. The session ID
2034 is returned into pointer provided as argument.

2091 caused the client to crash. Affecte file is
2092 lib/silcclient/client_prvmsg.c.
2094 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2096 * Added function silc_client_add_channel,
2097 silc_client_replace_channel_id, and removed functions
2098 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2099 from client library.
2101 * Added cross reference of the joined channels to the
2102 SilcClientEntry, and changed the SilcChannelEntry's
2103 users list to SilcHashTable. The affected files are
2104 lib/silcclient/idlist.[ch].
2106 * Fixed a bug in hash table tarversing. While the hash table
2107 is traversed with SilcHashTableList the table must not be
2108 rehashed. It is now guaranteed that auto rehashable tables
2109 are not rehashed while tarversing the list. Also defined that
2110 silc_hash_table_rehash must not be called while tarversing
2111 the table. Added function silc_hash_table_list_reset that must
2112 be called after the tarversing is over. The affected files are
2113 lib/silcutil/silchashtable.[ch].
2115 * Changed all hash table traversing to call the new
2116 silc_hash_table_list_reset in server and in client library.
2118 * Added function silc_client_on_channel to return the
2119 SilcChannelUser entry if the specified client entry is joined
2120 on the specified channel. This is exported to application as
2121 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2123 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2125 * Fixed founder regaining problem with JOIN command on normal
2126 server. The notify for mode change must be sent always and
2127 not only if !cmd->pending. Affected file silcd/command.c.
2129 * Fixed the WHOWAS command's reply sending to support the
2130 lists correctly. Affected file silcd/command.c.
2132 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2134 * When sending JOIN command to router for processing the
2135 sender's old command identifier was not saved back to the
2136 sender's command context, fixed now. The affected file is
2139 * Create the key in JOIN command of the router did not return
2140 the channel key, added check for this. Affected file is
2143 * Fixed a channel ID update bug in JOIN command reply. Do
2144 not directly upgrade the ID but call the function
2145 silc_idlist_replace_channel_id if the ID was changed.
2146 Affected file silcd/command_reply.c.
2148 * Fixed memory leaks from command calling if it would fail.
2149 Affected file silcd/command.c.
2151 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2153 * Applied patches from cras:
2155 Memory leak fixes around libaries, irssi window resize fix,
2156 new silclist.h and silcdlist.h, all extern inline changed to
2159 * Removed dotconf from lib/dotconf, not needed anymore.
2161 * Removed TRQ from lib/trq, not needed anymore.
2163 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2164 with server connections. Later this will be configurable
2165 in config file after new config file is done. Affected file
2168 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2170 * Fixed a crash in server related to channel announcements.
2171 Affected file silcd/server.c.
2173 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2175 * Fixed memory leaks in silc_server_create_new_channel*
2176 functions. Affected file silcd/server.c.
2178 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2179 which ID was changed. This way the router will send the
2180 user list for the channel again, and server won't be in
2181 desync in some rare circumstances. Affected file is
2182 silcd/packet_receive.c.
2184 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2186 * Check for NULL socket pointer in the function
2187 silc_server_packet_send_to_channel_real. Affected file
2188 silcd/packet_send.c.
2190 * Fixed the BAN notify handling to correctly remove ban
2191 list. Affected file silcd/packet_receive.c.
2193 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2195 * Fixed some header addition to Toolkit distribution in
2196 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2198 * Added lib/silcclient/client_ops_example.h as an template
2199 file for application programmers to quickly start using
2200 the SilcClientOperation functions in their application.
2201 Updated the lib/silcclient/README as well to tell about this
2202 nice file made available.
2204 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2206 * Call silc_server_remove_from_channels when removing client
2207 entry when NO_SUCH_CLIENT_ID was received. Affected file
2208 is silcd/command_reply.c.
2210 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2212 * Added server & router operator statistics updating. Affected
2213 file silcd/packet_receive.c and silcd/command.c.
2215 * Fixed the SERVER_SIGNOFF notify handling on normal server
2216 not to save the history information for clients. Same was
2217 fixed earlier in remove_clients_by_server function, but not
2218 here. Affected file silcd/packet_receive.c.
2220 * Raised the default connection-retry count from 4 to 7 in
2221 server. Affected file silcd/server.h.
2223 * Cancel any possible reconnect timeouts when we start the
2224 key exchange. Affected file silcd/server.c.
2226 * Do not reconnect on connection failure when SCONNECT was
2227 given. Affected files silcd/server.[ch].
2229 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2231 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2233 * Fixed the NICK command to always give the unformatted
2234 nickname to the one giving the NICK command. If unformatted
2235 nickname is cached already it will be formatted and the
2236 local entry will always get the unformatted nickname.
2237 Affected file lib/silcclient/idlist.c.
2239 * Fixed some double frees from client library commands.
2240 Affected file is lib/silcclient/command.c.
2242 * Fixed CUMODE command in server to assure that no one can
2243 change founder's mode than the founder itself, there was a
2244 little bug. Affected file silcd/command.c.
2246 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2248 * Removed the SilcClientCommandDestructor from the client
2249 libary, it is not needed anymore. Affected files are
2250 lib/silcclient/silcapi.h, command[_reply].[ch],
2251 client_notify, idlist.c.
2253 * Fixed GETKEY command to first resolve client, and then
2254 resolve the server only if the client was not found, instead
2255 of resolving both at the same time. Affected file is
2256 lib/silcclient/command.c.
2258 * Added silc_client_start_key_exchange_cb and lookup the
2259 remote hostname and IP address before starting the key
2260 exchange with server. The affected file is
2261 lib/silcclient/client.c.
2263 * The server's public key is now saved using the IP address
2264 of the server and not the servername for the filename.
2265 The hostname public key filename is checked as an fall back
2266 method if the IP address based filename is not found.
2268 Fixed the GETKEY command to save the fetched server key
2269 in correct filename.
2271 Print the remote server's hostname now when new key is
2272 received during connection process. Affected file is
2273 irssi/src/silc/core/client_ops.c.
2275 * Return always our own public key to the client if it asks
2276 for it with GETKEY command. Affected file silcd/command.c.
2278 * Removed the use_auto_addr variable from default config
2279 file since it was in wrong section. Affected file is
2282 * Fixed TOPIC_CHANGE notification to not route it when it
2283 was sent using silc_server_send_notify_to_channel function.
2284 Affected file silcd/command.c.
2286 * Fixed silc_server_send_notify_kicked to send the kicker's
2287 Client ID also, it was missing. Affected files are
2288 silcd/command.c, silcd/packet_send.[ch].
2290 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2292 * Do not save client history information in SERVER_SIGNOFF.
2293 Fixes the bug in normal server that it does not detect
2294 the client becoming valid after the server becomes back
2295 online. Affected file silcd/server_util.c.
2297 * Added `sock_error' field into the SilcSocketConnection
2298 context. When error occurs during socket operation (read
2299 or write) the error is saved. Added also new function
2300 silc_socket_get_error to return human readable socket error
2301 message. Affected files are lib/silcutil/silcsockconn.[ch],
2302 lib/silcutil/unix/silcunixsockconn.c, and
2303 lib/silcutil/win32/silcwin32sockconn.c.
2305 * The server now prints the socket error message in the
2306 signoff for client. Affected file silcd/server.c.
2308 * Fixed the `created' channel information sending from router
2309 to server in JOIN command. Checks now whether the channel
2310 really was created or not and set it according that.
2312 Fixed the JOIN command to use the client entry's current
2313 ID during the joining procedure instead of the one it sent
2314 in the command (it is checked though), since it can change
2315 between the packet processing and command processing, and
2316 would just case unnecessary pain in the client end. Affected
2317 file silcd/command.c.
2319 * Fixed a channel key payload sending to use correct channel
2320 ID when the server was forced to change the channel's ID by
2321 router. Router sent the key payload with the old Channel ID.
2322 Affected file silcd/packet_receive.c.
2324 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2326 * Call silc_server_save_channel_key only if the key payload
2327 was provided in the JOIN command's command reply. Affected
2328 file silcd/command_reply.c.
2330 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Fixed silc_mp_sizeinbase to return the value correctly with
2333 MPI. Affected file lib/silcmath/mp_mpi.c.
2335 * Fixed the stop_server signal to correctly stop the scheduler
2336 and gracefully stop the server when SIGTERM or SIGINT signals
2337 are received. Affected file silcd/silcd.c.
2339 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2341 * Simple handling of TERM and HUP signals. Also added some log
2342 flushing call around. Affected file is
2345 * Fixed small bugs in silclog.c. Now buffering output will take
2346 effect after 10 seconds since startup: This will ensure that
2347 no important startup messages are lost. Also output redirection
2348 will preserve original format ([Date] [Type] message).
2349 Affected file is lib/silcutil/silclog.c.
2351 * Added two options to the config file, in the logging section:
2352 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2353 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2355 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2357 * Do not print the warning about log files not being initialized
2358 more than once to avoid excess logging. Affected file is
2359 lib/silcutil/silclog.c.
2361 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2362 the SIM copying in make install in Makefile.am.pre.
2364 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2366 * Rewritten silclog APIs. Globally interesting changes follows:
2367 silc_log_set_files() changed to silc_log_set_file().
2368 silc_log_set_callbacks() changed to silc_log_set_callback().
2369 ROBOdoc documented silclog header file.
2370 SilcLogCb now returns bool to wether inihibit the default
2371 handler or not (to keep the old behaviour return always TRUE).
2372 The new APIs should also fix the problem of the
2373 silcd_error.log file that was written in the current directory.
2376 Log files streams will remain opened after silc_log_set_file()
2377 call, means less CPU usage notably on high traffic servers.
2378 File streams are now full buffered, and flushed to the disk
2379 every 5 minutes, lesses HD activity and CPU usage.
2380 Messages can be redirected, allowing admins to configure
2381 one single logfile for all server messages.
2382 the silc_log_quick global variable to activate fast-logging.
2383 Affected files lib/silcutil/silclog.[ch]
2385 * Changed some code to conform new silclog APIs. Affected
2386 files are doc/example_silcd.conf.in, silcd/server.c
2387 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2390 * Fixed a memory leak that could occur in some situations.
2391 Affected file silcd/serverconfig.c.
2393 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2395 * Added the silc_client_del_client to remove the client from
2396 all channels as well. Affected file lib/silcclient/idlist.c.
2398 * Fixed the client library to correctly remove the client
2399 from all channels when the client entry is being destroyed.
2400 Affected file lib/silcclient/client_notify.c, command.c.
2402 * Added auto-nicking support to the client library. If the
2403 applicatio now sets client->nickname it will be sent to the
2404 server after connecting by the library. This way for example
2405 SILCNICK (or IRCNICK) environment variables will have effect
2406 and always change the nickname automatically to whatever
2407 it is wanted. Affected file lib/silcclient/client.[ch].
2409 * Renamed silc_server_command_bad_chars to the
2410 silc_server_name_bad_chars and moved it to the
2411 silcd/server_util.[ch]. Added also new function
2412 silc_server_name_modify_bad to return nickname that
2413 includes bad characters as new nickname without those
2414 bad characters. This check and modify is now used in
2415 silc_server_new_client when the username is initially set
2416 as nickname, so it must be checked to be valid nickname.
2417 Affected file silcd/packet_receive.c.
2419 * The nickname length is now taken from the packet for real
2420 and not trusted to strlen() since it clearly can return
2421 wrong length for nickname including bad characters. This
2422 also applies to channel names. Affected file silcd/command.c.
2424 * Removed the lib/silcsilm/modules directory. Modules are now
2425 compiled into the lib/silcsim. Fixed the copying of the
2426 modules to follow symbolic links in Makefile.am.pre.
2428 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2430 * Fixed silc_string_regexify list creation. Fixes bugs with
2431 BAN and INVITE commands in server. The affected file is
2432 lib/silcutil/unix/silcunixutil.c.
2434 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Removed the command destructor entirely from the server's
2437 command and command reply routines. It is not needed, and
2438 its usage was buggy and caused crashes. Affected files are
2439 silcd/command[_reply].[ch].
2441 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Cancel protocol and NULL sock->protocol if timeout
2444 occurred during protocol. Affected file silcd/server.c.
2446 * Cancel protocol timeouts always before calling the final
2447 callback, to assure that after final callback is called
2448 no other state will be called for the protocol anymore.
2449 Affected file silcd/protocol.c.
2451 * Print error log if incoming connection configuration could
2452 not be found. Affected file silcd/server.c.
2454 * Fixed JOIN command to correctly save the founder mode
2455 to the client on normal SILC server, when the channel
2456 was created by the router. Affected file silcd/command.c.
2458 * Fixed LIST command (hopefully) to send correct reply
2459 packets. Affected file silcd/command.c.
2461 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * The silc_packet_receive_process now returns FALSE if the
2464 read data was invalid packet, and TRUE if it was ok.
2466 The server now checks that if unauthenticated connection
2467 sends data and its processing fails the server will close
2468 the connection since it could be a malicious flooder.
2470 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2472 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Make sure the warning about error opening a log file is
2475 printed only once and not everytime it fails (produces
2476 too much useless log). Affected file lib/silcutil/silclog.c.
2478 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2480 * Made the silc_server_daemonise() function more readable.
2481 Affected file silcd/server.c.
2483 * Pid file is now optional, the user may comment it out from
2484 the config file. Removed define SILC_SERVER_PID_FILE, we
2485 don't need a default any longer. Affected file
2486 configure.in.pre, lib/Makefile.am.pre.
2488 * Make some use of the pid file. The server now dies at startup
2489 if it detects a valid pid file on his path. The server would
2490 die anyway in this circumstance, because of the bind() failure.
2491 Affected file silcd/silcd.c.
2493 * No longer compiling lib/dotconf.
2495 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Fixed JOIN command parsing not to crash. Affected file
2498 lib/silcclient/command.c.
2500 * Fied the NICK_CHANGE notify to add the new client entry
2501 even it is resolved. This removes an <[unknown]> nick
2502 thingy bug in the client. Affected file is
2503 lib/silcclient/client_notify.c.
2505 * Do not try to allocate 0 bytes (efence does not like it)
2506 in lib/silccore/silccomand.c when encoding payload.
2508 * Do not take IRCNICK as nickname in Irssi SILC client since
2509 it is not possible to set nickname before hand connecting
2510 the server (TODO has an entry about adding auto-nicking
2513 * Changed the silc_server_command_pending to check whether
2514 there already exists an pending entry with the specified
2515 command, command identifier and pending callback. This is
2516 to fix IDENTIFY and WHOIS related crashes that may register
2517 multiple pending commands with same identifier. Affected
2518 file silcd/command.c.
2520 * Fixed the server to reconnect to the router even if it
2521 was already reconnecting and EOF was received. This to
2522 fix a possibility that the server wouldn't ever try to
2523 auto-reconnect to the router. Affected file silcd/server.c.
2525 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Fixed the server's password authentication to use the
2528 length of the locally saved password, and not the one
2529 sent in the packet. Affected file silcd/protocol.c.
2531 * Fixed same password authentication problem in the
2532 Authentication Payload handling routines in
2533 lib/silccore/silcauth.c.
2535 * Yet another password authentication problem fixed with
2536 channel password handling in silcd/command.c.
2538 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * If first character of string in silc_parse_userfqdn is '@'
2541 then do not parse it. Affected file is
2542 lib/silcutil/silcutil.c.
2544 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Fixed minor bug in IDENTIFY command reply sending, which
2547 caused various weird problems during JOIN when it was
2548 resolving names for users. Affected file silcd/command.c.
2550 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Fixed the IDENTIFY command reply sending to chech better valid
2553 clients. It was possible to send incomplete list of replies.
2554 Affected file silcd/command.c.
2556 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Added silc_client_command[s]_[un]register functions now to
2559 dynamically register the commands in client library. Removed
2560 the static table of commands. This allows the client library
2561 to call commands without causing the application to know about
2562 what commands library has called.
2564 Removed the INFO command reply kludge to detect when the command
2565 was called by library. Now library use its own command reply
2566 function for INFO command.
2568 Added function silc_client_command_call to call a command.
2569 Application can use it to call command, not access the structure
2572 Now all commands that are sent by the client library (not
2573 explicitly sent by application) use own command reply functions.
2575 Affected files around lib/silcclient/ and in
2576 irssi/src/silc/core/.
2578 * Fixed the WHOIS command reply sending to chech better valid
2579 clients. It was possible to send incomplete list of replies.
2581 Fixed the WHOIS and IDENTIFY to send the request to router
2582 if normal server did not do it and did not find any results.
2584 Affected file silcd/command.c.
2586 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Moved the internal data from SilcClient context into its
2589 own file, not accesible to application. Affected files
2590 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2591 and other files in client library.
2593 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Added doc/examples installation target in Makefile.am.pre.
2598 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2601 commands the found client entry will be removed from the
2602 cache, after notifying application about the error. Affected
2603 file lib/silcclient/command_reply.c.
2605 * Changed the /MSG to check for exact nickname user gave, and
2606 not let `nick' match `nick@host' if it is only one found. Now,
2607 user must type the exact nickname (like nick@host2) even if
2608 there are no more than one same nicks found. This is to avoid
2609 a possibility of sending nickname to wrong nickname since
2610 `nick' could match `nick@host'. Affected file is
2611 irssi/src/core/silc-servers.c.
2613 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Do not print "you are now server operator" or similar when
2616 giving /away command. Affected files are
2617 irssi/src/silc/core/client_ops.c, silc-servers.h.
2619 * Made the silc_server_command_pending_error_check to send
2620 the same command reply payload it received back to the
2621 original sender of the command. This way all arguments
2622 that was received by the server will be received by the
2623 client too. Affected file silcd/command.c.
2625 * Added the silc_idcache_add to return the created cache entry
2626 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2628 * Add global clients to expire if they are not on any channel.
2629 This is because normal server will never know if they signoff
2630 if they are not on any channel. The cache expiry will take
2631 case of these entries. This is done by normal servers only.
2632 The affected files are silcd/command_reply.c,
2633 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2635 * If server receives invalid ID notification for WHOIS or
2636 IDENTIFY and the ID exists in the lists, it is removed.
2637 Affected file silcd/command_reply.c.
2639 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2640 in client then client entry that it matches is searched and
2641 the nickname is printed on the screen for user. Affected
2642 file irssi/src/silc/core/client_ops.c.
2644 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Use cache entry expire time in the LIST command reply to
2647 purge old entries from the cache after the LIST command
2648 reply has been received. This way we don't have non-existent
2649 entries in the cache for too long. Affected file is
2650 silcd/command_reply.c.
2652 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * If we are normal server, and we've not resolved client info
2655 in WHOIS or IDENTIFY from router, and it is global client,
2656 we'll check whether it is on some channel. If it is not
2657 then we cannot be sure about its validity and will resolve it
2658 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2659 file silcd/command.c.
2661 * Search channel by name (if possible) rather than by ID
2662 in IDENTIFY command's command reply. Affected file is
2663 silcd/command_reply.c.
2665 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2668 Updated specs and implemented it. Affected file silcd/command.c,
2669 silcd/packet_send.c and silcd/packet_receive.c.
2671 * Implemented the <founder auth> payload handling in the JOIN
2672 command. If provided all conditions for channel joining
2673 except requirement to provide correct passphrase can be
2674 overrided by the channel founder. Updated the protocol specs.
2675 Affected file silcd/command.c.
2677 Added support for founder auth in JOIN command in client
2678 library. Fixed the parsing of the JOIN command now to support
2679 all options as they should be. The affected file is
2680 lib/silcclient/command.c.
2682 * Optimized the WHOIS and IDENTIFY commands to send the request
2683 to router only if it includes nicknames or other names. If
2684 they include only IDs then check the local cache first before
2685 routing. Affected file is silcd/command.c.
2687 * Added channels topic announcements. Affected file is
2688 silcd/packet_receive.c and silcd/server.c.
2690 * Fixed the silc_server_send_notify_topic_set to really destine
2691 the packet to channel. Affected file silcd/packet_send.c.
2693 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2694 library. Affected file lib/silcclient/client_notify.c.
2696 * Added UMODE announcements. Affected file silcd/server.c.
2698 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Memory leak fixes in:
2702 lib/silcutil/silcsockconn.c
2703 lib/silcske/silcske.c
2704 lib/silcske/groups.c
2706 lib/silccrypt/silcpkcs.c
2707 lib/silccore/silccommand.c
2708 lib/silccore/silcidcache.c
2713 * ROBOdoc documented the lib/silcske/groups.h file and a
2714 bit changed the interface for better.
2716 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2718 * Update the client entry context in the ID cache after
2719 nick change. Affected file lib/silcclient/command.c.
2720 Fixes the CUMODE command when regaining founder privileges,
2721 and a little WHOIS problem.
2723 * Fixed silc_net_gethostbyname to correctly call the
2724 inet_ntop. Affected file lib/silcutil/silcnet.c.
2726 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2728 * Added IPv6 support checking to the configure.in.pre, added
2729 also --enable-ipv6 option to override the check. Affected
2730 file configure.in.pre.
2732 * The silc_thread_create now calls the start function
2733 directly if threads support is not compiled in. Removes
2734 ugly #ifdef's from generic code. Affected files are
2735 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2737 * Added silc_net_gethostby[name/addr]_async to asynchronously
2738 resolve. Affected files are lib/silcutil/silcnet.[ch].
2740 * Added support for rendering IPv6 based server, client and
2741 channel IDs. Affected file lib/silcutil/silcutil.c.
2743 * Added support for creating IPv6 based server IDs. Affected
2744 file is silcd/serverid.c.
2746 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2748 * Added silc_net_gethostby[addr/name] into the
2749 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2750 routines. Added silc_net_is_ip[4/6]. Affected file is
2751 lib/silcutil/unix/silcunixnet.c. All routines that take
2752 address as argument now supports both IPv4 and IPv6 addresses.
2754 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2756 * Fixed LIST command reply sending in server. Affected file
2759 * Server now sends the kicker's client ID in the KICK notify
2760 to the kicked client. Affected file silcd/command.c.
2762 * The client library now parses the kickers client ID and
2763 UI displays it. Affected files lib/silcclient/client_notify.c
2764 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2766 * Made all payload parsing function prototypes consistent.
2767 They all take now const unsigned char * and uint32 pair as
2768 the payload data instead of SilcBuffer. Changes all around
2769 the source tree. Other unsigned char* -> const unsigned char*
2770 changes around the tree as well.
2772 * Optimized SFTP client and server packet sending not to
2773 allocate new buffer for each packet but to recycle the
2774 first allocated buffer. Affected files are
2775 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2777 * Optimized the SFTP client to use SilcList instead of
2778 SilcDList for requests, because it is faster. Affected file
2779 is lib/silcsftp/sftp_client.c.
2781 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2782 into lib/silccore/silcid.[ch].
2784 Renamed silcpayload.[ch] into silcargument.[ch].
2786 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * If client entry is deleted with active key agreement
2789 session, abort the session.
2791 The silc_client_abort_key_agreement now calls the completion
2792 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2794 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2797 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Don't use __restrict in older GCC's. Affected file is
2800 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2802 * silc_net_localhost now attempts to reverse lookup the
2803 IP/hostname. Affected file lib/silcutil/silcnet.c.
2805 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2806 command. It can be used to gain founder privileges at
2807 the same time when joining the channel.
2809 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2810 kicker's client ID as well. Updated protocol specs.
2812 Defined that the server must send SILC_COMMAND_IDENTIFY
2813 command reply with error status to client who sent
2814 private message with invalid client ID.
2816 Updated the protocol specification.
2818 * Added silc_server_send_command_reply to send any
2819 command reply. Affected file silcd/packet_send.[ch].
2821 * Added silc_id_payload_encode_data to encode ID payload
2822 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2824 * The server now send IDENTIFY command reply with error
2825 status if client ID in private message is invalid. Affected
2826 file silcd/packet_receive.c.
2828 * Save the server key file with server's IP address in
2829 the filename instead of hostname. The affected file is
2830 irssi/src/silc/core/client_ops.c.
2832 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2837 * Added libtool support for compiling shared objects in
2838 lib/silcsim. Affected file configure.in.pre and
2839 lib/silcsim/Makefile.am. Original patch by cras.
2841 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Pid file configuration, and server's config file fixes
2844 patch by toma. Updated CREDITS file.
2846 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Fixed silc_client_channel_message to not try to decrypt
2849 the message twice if it resolved the destination client
2850 information. This could cause of dropping one channel
2851 message. Affected file lib/silcclient/client_channel.c.
2853 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2856 lib/silcclient/client.c. This function is used when the SILC
2857 Client is run under some other scheduler, or event loop or
2858 main loop. On GUI applications, for example this may be
2859 desired to used to run the client under the GUI application's
2860 main loop. Typically the GUI application would register an
2861 idle task that calls this function multiple times in a second
2862 to quickly process the SILC specific data.
2864 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2866 * Fixed silc_server_drop() for dropping the supplementary
2867 groups as well, this could cause a security hole on some
2870 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2875 * Write PID file after dropping privileges. Added -F option
2876 to run server on foreground. A patch by debolaz.
2877 Affected files silcd/server.c, silcd/silcd.c.
2879 * Fixed MOTD to return the MOTD file server name. Affected
2880 file silcd/command.c.
2882 * Added INFO command reply handling to the Irssi SILC Client.
2883 Affected file irssi/src/silc/core/client_ops.c.
2885 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed the silc_idcache_list_* routines to really support
2888 the dynamic list. Fixes a crash. Affected file is
2889 lib/silccore/silcidcache.c.
2891 * Fixed the LIST command reply to really call LIST command's
2892 pending callbacks. Affected file silcd/command_reply.c.
2894 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Update conn->local_entry->nickname after giving NICK
2897 command. Affected file lib/silcclient/command.c.
2899 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2901 * Added the [pid] option to the silcd configuration file
2903 Affected files: serverconfig.[ch] and silcd.c
2905 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Save fingerprint in WHOIS command reply in server.
2908 Affected file silcd/command_reply.c.
2910 * Fixed NICK commands pending callback registration.
2911 Affected file lib/silcclient/command.c.
2913 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Use ++server->cmd_ident when sending commands in server,
2916 instead of random number. Affected file silcd/command.c.
2918 * Fixed GETKEY command reply to call actually GETKEY pending
2919 command callbacks. Affected file silcd/command_reply.c.
2921 * A bit stricter check for nicknames. Check for same nickname
2922 in NICK command also. Affected file silcd/command.c.
2924 * Do not call INFO command everytime client ID changes, only
2925 during first connecting. Affected file lib/silcclient/client.c.
2927 * Set the new nickname only after successful command reply for
2928 NICK command is returned by server. Affected file
2929 lib/silcclient/command.c.
2931 * Remove nicknames from nicklist during server_signoff notify.
2932 Should fix /NAMES bit more. The affected file is
2933 irssi/src/silc/core/silc-channels.c.
2935 * Added `fingerprint' field to the SilcIDListData in the
2936 silcd/idlist.h to hold the fingerprint of the client's
2939 Send the fingerprint of the client's public key in WHOIS
2942 Affected files silcd/command.c, and silcd/idlist.[ch].
2944 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2945 create fingerprint from given data.
2947 * Show the fingerprint of the client's public key in WHOIS.
2948 Affected files irssi/src/module-formats.[ch] and
2949 irssi/src/silc/core/client_ops.c.
2951 * Format the multiple same nicknames also during JOIN and
2952 NICK_CHANGE notifys. Affected file is
2953 lib/silcclient/client_notify.c.
2955 * Do not print error on screen for invalid private message
2956 payload since it can come if someone is sending private
2957 messages with wrong key. Affected file
2958 lib/silccore/silcprivate.c.
2960 * Fixed multiple concurrent /PING crash. Affected file
2961 lib/silcclient/command.c.
2963 * Changed the wrong ID encoding. All IP addresses must be
2964 in MSB first order in encoded format. They were encoded
2965 wrong and was in LSB format. Affected files are
2966 silcd/serverid.c, lib/silcutil/silcutil.c.
2968 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2970 * Call the `connect' client operation through the scheduler
2971 in case of error. Affected file lib/silcclient/client.c.
2973 * Call the `failure' client operation even if the error
2974 occurred locally during a protocol. Affected file is
2975 lib/silcclient/protocol.c.
2977 * Added support of sending LIST command to router from normal
2978 server. This way normal server can get list of all channels
2979 in the network too. Fixed the channel list sending in the
2980 server too. Affected files are silcd/command.c, and
2981 silcd/command_reply.[ch].
2983 * Added silc_server_update_channels_by_server and
2984 silc_server_remove_channels_by_server. They are used during
2985 disconnection of primary router and in backup router protocol.
2986 Affected file silcd/server_util.[ch], silcd/server.c and
2987 silcd/server_backup.c.
2989 * Fixed channel adding to global list in IDENTIFY command
2990 reply in server. Affected file silcd/command_reply.c.
2992 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * If the incoming packet type is REKEY or REKEY_DONE process
2995 that packet always synchronously. Fixes yet another MAC
2996 failed error on slow (dialup) connections. Affected file
2997 lib/silcclient/client.c and silcd/server.c.
2999 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Call check_version SKE callback for initiator too. Affected
3002 file lib/silcske/silcske.c.
3004 * Implemented fix for security hole found in the SKE that was
3005 fixed in the specification few days back; the initiator's
3006 public key is now added to the HASH value computation.
3007 Added backwards support for the old way of doing it too, for
3008 old clients and old servers. Affected file is
3009 lib/silcske/silcske.c.
3011 * Enabled mutual authentication by default in SKE. If initiator
3012 is not providing mutual authentication the responder will
3013 force it. This will provide the proof of posession of the
3014 private key for responder. The affected files are
3015 lib/silcclient/protocol.c and silcd/protocol.c.
3017 * Do not cache anymore the server's public key during SKE.
3018 We do mutual authentication so the proof of posession of
3019 private key is done, and if the server is authenticated in
3020 conn auth protocol with public key we must have the public
3021 key already. Affected file silcd/protocol.c.
3023 * Added new global debug variable: silc_debug_hexdump. If
3024 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3025 file lib/silcutil/silclog.[ch].
3027 * Fixed compilation warning due to char * -> const char *.
3028 Affected files lib/silcutil/silcnet.h, and
3029 lib/silccore/silcauth.[ch].
3031 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Fixed CMODE command when new channel key was created. If
3034 the creation failed the old key was removed. Next time giving
3035 same command would crash the server since the old key was
3036 freed already. Affected file silcd/command.c.
3038 * Fixed the silc_server_announce_get_channels to not crash
3039 on reconnect. Affected file silcd/server.c.
3041 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Added silc_log_set_debug_string function to set a regex
3044 string to match for debug output. Only the function names,
3045 or filenames matching the given debug string is actually
3046 printed. This way it is possible to filter out those debug
3047 strings that user is not interested in.
3049 Fixed a bug in silc_string_regexify.
3051 Affected files lib/silcutil/silclog.[ch], and
3052 lib/silcutil/unix/silcunixutil.c.
3054 * Changed the -d options in both server and Irssi SILC client
3055 to take the debug string as argument. Affected files
3056 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3058 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Added silc_hash_babbleprint to create a Bubble Babble
3061 Encoded fingerprint. The encoding is developed by Antti
3062 Huima (draft-huima-babble-01.txt), and it creates human
3063 readable strings out of binary data. Affected file
3064 lib/silccrypt/silchash.[ch].
3066 * Print the babble print now in addition of fingerprint as well
3067 in Irssi SILC client. Affected files are
3068 irssi/src/fe-common/silc/module-formats.[ch],
3069 irssi/src/fe-common/silc/core/client_ops.c.
3071 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Fixed a security problem found in SKE. The initiator's
3074 public key too is now added to the HASH hash value creation
3075 which is signed by the responder to create the SIGN value.
3076 This will prevent anyone in the middle to lie to the responder
3077 about the initiator's public key. If this is done now, the
3078 man in the middle will get caught. Updated the protocol
3081 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Better installation directory handling. Configure module
3084 paths and other paths automatically to example_silc* files
3085 in doc/. A patch by toma.
3087 * Fixed compiler warning from MPI library, and from SILC RNG.
3090 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3091 It can be configured with ./configure. A patch by toma.
3093 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Find correct make to use in prepare-clean. A patch by
3096 toma. Affected file prepare-clean.
3098 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3100 * Added irssi variables use_auto_addr, auto_bind_ip,
3101 auto_bind_port and auto_public_ip.
3103 * Changed the interface for silc_client_send_key_agreement
3104 in lib/silcclient/silcapi.h
3108 irssi/src/silc/core/silc-core.c
3110 lib/silcclient/silcapi.h
3111 irssi/src/silc/core/silc-channels.c
3112 lib/silcclient/client_keyagr.c
3115 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Added silc_pkcs_public_key_compare to compare two
3118 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3120 * Check that the client who set the founder mode on the
3121 channel is the same client that is giving the founder
3122 mode to itself. It is done by comparing the saved public
3123 key (it is saved even in the authentication is passphrase).
3124 Affected file silcd/command.c.
3126 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3128 * Do not process packet for disconnected socket connection.
3129 Affected file lib/silccore/silcpacket.c.
3131 * Process the DISCONNECT packet through scheduler in the
3132 client library. Affected file lib/silcclient/client.c.
3134 * Fixed the silc_client_packet_parse to not to increase
3135 the packet sequence number if the conn->sock and the
3136 current socket connection is not same. This can happen
3137 for example during key agreement when the conn includes
3138 multiple socket connections (listeners). Affected file
3139 lib/silcclient/client.c.
3141 * The sender of the file transfer request now provides also
3142 the pointer (listener) for the key exchange protocol. If
3143 the listener cannot be created then it sends empty key
3144 agreement and lets the receiver provide the listener.
3146 Added `local_ip' and `local_port' arguments to the
3147 silc_client_file_send. If they are provided they are used,
3148 if not then it will attempt to find local IP address, if
3149 not found or bind fails then the remote client will provide
3152 Affected files are lib/silcclient/client_ftp.c and
3153 lib/silcclient/silcapi.h.
3155 * Extended the FILE SEND command to support defining the

3229 silcd/server_util.c.
3231 * Fixed SERVER_SIGNOFF notify handling in the server. The
3232 server is now able to process incoming SERVER_SIGNOFF notify
3233 for a server that it doesn't even know about. It will remove
3234 the clients provided in the notify. Affected file
3235 silcd/packet_receive.c.
3237 * Check for partial packet in data queue after every packet that
3238 was found from the queue. Return and wait for more data if
3239 there is partial data in queue. Affected file is

3259 * Wrote a help file for FILE command.
3261 * Added silc_rng_global_get_byte_fast to get not-so-secure
3262 random data as fast as possible. Random data is read from
3263 /dev/urandom if available and from the SILC RNG if not
3264 available. It is used in padding generation. Affected file
3265 lib/silccrypt/silcrng.[ch].
3267 * All packets in client library are now processed synchronously.
3268 Optimized packet processing a lot. Affected file
3269 lib/silcclient/client.c.

3280 * Assure that silc_client_notify_by_server_resolve does not
3281 resolve the client information multiple times. If it cannot
3282 be found by the first it cannot be found at all. Affected
3283 file lib/silcclient/client_notify.c.
3285 * Fixed WHOWAS command reply calling. Affected file
3286 lib/silcclient/command_reply.c.
3288 * Removed all references to silc_idlist_get_client from the
3289 Irssi SILC client since that call is internal call used by
3290 the library. The Irssi SILC client will use now client
3291 retrieval functions found in silcapi.h.
3293 * Fixed a bug in resolving nickname info before sending
3294 private message. It used freed memory. Affected file
3295 irssi/src/silc/core/silc-servers.c.

3316 * Added silc_net_localip to return local host's IP address.
3317 Affected file lib/silcutil/silcnet.[ch].
3319 * If key exchange or rekey protocol is active for a connection
3320 parse all packets syncronously since there might be packets
3321 in packet queue that we are not able to process without first
3322 processing packets before them. Affected file silcd/server,
3323 lib/silcclient/client.c.
3325 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3326 whether library should continue processing the packet.
3327 Affected file lib/silccore/silcpacket.h.

3373 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3374 is incomplete and is being resolved, it won't be resolved
3377 Make sure also that USERS command reply does not resolve
3378 twice information. Affected file is
3379 lib/silcclient/command_reply.c.
3381 Make sure that silc_client_get_clients_by_list does not
3382 resolve twice same information.
3384 * Check for valid client->id in the silc_server_free_client_data.
3385 Affected file silcd/server.c.
3387 * Fixed /GETKEY nick@server not to crash if the server entry
3388 is not found. Affected file lib/silcclient/command.c.
3390 * Fixed the silc_server_check_cmode_rights to check the

3398 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Call the silc_server_udpate_servers_by_server in the
3401 primary router that comes back online in the backup resuming
3402 protocol. Otherwise it routes packets wrong. Affected file
3403 silcd/server_util.[ch], silcd/server_backup.c.
3405 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3408 lib/silcutil/silcbuffmt.[ch].
3410 * Redefined the SILC packet header to include the padding
3411 length. Affected file lib/silccore/silcpacket.[ch].
3413 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3414 length for maximum padding up to 128 bytes). Affected
3415 file lib/silccore/silcpacket.h.
3417 * Removed all backwards support for old 0.5.x MAC thingies.
3418 The SILC packet header change makes it impossible to be
3419 backwards compatible.
3421 * Send the ENDING packet with timeout in the backup resuming
3422 protocol. This is to assure that all routers has connected
3423 to the primary router. Affected file silcd/server_backup.c.
3425 * Changed the RNG to take the first IV from random data. It
3426 used to take it from zero actually. Changed the RNG also
3427 to use /dev/urandom during session. /dev/random is used
3428 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3430 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Changed the SILC packet header to have the first two bytes
3433 (the packet length) encrypted. Affected files aroung the
3434 code tree, lib/silccore/silcpacket.[ch]. Removed the
3435 SilcPacketCheckDecrypt callback. It is not needed anymore
3436 since the silc_packet_receive_process will determine now
3437 whether the packet is normal or special.
3439 * Implemented the unidirectional MAC keys. Affected files
3440 lib/silcske/silcske.c, silcd/protocol.c and
3441 lib/silcclient/protocol.c.
3443 * Implemented the packet sequence number to the MAC computation.
3444 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3445 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3446 lib/silcclient/protocol.c.
3448 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Allow backup router to announce servers. All servers
3451 announced by backup router are added to the global list
3452 automatically. Update hte server's socket to our primary
3453 router also when backup router announces a server.
3454 Affected file silcd/packet_receive.c.
3456 * Do not update the client->router in the function
3457 silc_server_udpate_clients_by_server if the client is on
3458 global list. We might fail to find any specific server
3459 for locally connected clients and local cell clients. They
3460 should still use the `from' and not `to' as client->router.
3461 This fixes backup router resuming protocol. Affected file
3462 silcd/server_util.c.
3464 * Decrease channel statistics count only if the channel
3465 deletion worked. Affected files are silcd/server.c and
3466 silcd/server_util.c.
3468 * Added silc_server_update_servers_by_server to update origin
3469 of all server entries. Used during backup router protocol.
3470 Affected files silcd/server_util.[ch], silcd/server.c. and
3471 silcd/backup_router.c.
3473 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3474 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3475 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3476 lib/silccrypt/silchmac.c.
3478 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Assure that router cannot reroute the same channel message
3481 to the sender. Affected file silcd/packet_receive.c.
3483 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3485 * Made better checks that the channel message is not sent
3486 to the router it came from. Affected file is
3487 silcd/packet_send.c. Fixed memory leak too.
3489 * Announce informations for incoming router connection, but
3490 only after checking if it is replaced by backup router.
3491 Affected file silcd/packet_receive.c.
3493 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Fixed the backup resuming protocol to work in multiple
3496 router environment. Affected file silcd/server_backup.c.
3498 * Route packet only to one router in the function
3499 silc_server_packet_send_to_channel. Affected file is
3500 silcd/packet_send.c.
3502 * Fixed silc_server_send_notify_dest to set the broadcast
3503 flag. Fixed the silc_server_send_notify_topic to actually
3504 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3505 Affected file silcd/packet_send.c.
3507 * Changed the SFTP Filesystem interface. Changed the
3508 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3509 the filesystem operation function. The SilcSFTPFilesystem
3510 is now a context that is allocated by all filesystem allocation
3511 functions and it already includes the operations structure
3512 and filesystem specific context. It is given as argument
3513 now to the silc_sftp_server_start. This made the interface
3514 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3515 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3517 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3519 * Changed the backup router adding and getting interfaces
3520 in the server. The router that will be replaced by the
3521 specified backup router is now sent as argument. Affected
3522 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3525 * Added silc_net_addr2bin_ne to return the binary form of
3526 the IP address in network byte order. Affected files
3527 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3529 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Check for existing server ID in silc_server_new_server
3532 and in silc_server_connect_to_router_final and remove the
3533 old entry if it exists. Affected file silcd/packet_receive.c,
3536 * Send the channel message always to only one router, either
3537 in upstream or downstream. Affected file is
3538 silcd/packet_send.c.
3540 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3542 * Wrote the definition of the backup resuming protocol to the
3543 protocol specification.
3545 * Removed one redundant channel key generation from normal
3546 server during joining procedure. Removed one redundant
3547 channel key sending from server to router during joining
3548 procedure. Affected file silcd/command.c.
3550 * Made minor bugfixes to the backup router resuming protocol.
3551 Affected file silcd/server_backup.c, server.c.

3555 * Added --disable-asm configuration option. Affected files
3556 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3559 * Implemented the backup resuming protocol that is used to
3560 resume the primary router position in the cell after the
3561 primary router comes back online. Affected files
3562 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3563 and silcd/server_util.[ch].
3565 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Sleep two (2) seconds after sending QUIT command to server.
3568 Affected file lib/silcclient/command.c.
3570 * Assure that if outgoing data buffer is pending do not force
3571 send any data. Affected file silcd/packet_send.c.
3573 * Assure that if outgoing data buffer is pending do not force
3574 send any data. Affected file lib/silcclient/client.c.
3576 * Implemented the backup router support when the primary router
3577 goes down. The servers and routers can now use the backup
3578 router as new primary router without loosing connectivity.
3580 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3583 in the server to indicate disabled entry. All data read
3584 from the connection will be ignored and no data is sent
3585 for entry that is disabled. Affected files are
3586 silcd/idlist.h, silcd/server.c.
3588 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Created SFTP client and server test programs in the
3591 lib/silcsftp/tests directory.
3593 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Implemented memory filesystem (virtual filesystem) for
3596 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3599 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Implemented the SFTP (SSH File Transfer Protocol) to the
3602 lib/silcsftp. It includes SFTP client and SFTP server
3605 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Moved lib/silccore/silcprotocol.[ch] to the
3608 lib/silcutil library.
3610 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3611 take variable argument list pointer as argument. Affected
3612 file lib/silcutil/silcbuffmt.[ch].
3614 * Added silc_buffer_set function that is used to set data
3615 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3616 Affected file lib/silcutil/silcbuffer.h.
3618 * Changed various routines in the core library to use the new
3619 silc_buffer_set instead of allocating new buffer only for
3622 * Added 64-bit value formatting and unformatting support to the
3623 silc_buffer_[un]format routines. Affected file is
3624 lib/silcutil/silcbuffmt.[ch].
3626 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3627 to includes/bitmove.h.
3629 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Fixed channel user mode saving in client library. Affected
3632 file lib/silcclient/command[_reply].c.
3634 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Defined the file transfer to the SILC Protocol. Added
3637 new packet type SILC_PACKET_FTP and defined File Transfer
3638 Payload. The mandatory file transfer protocol is SFTP
3639 (SSH File Transfer Protocol). Affected file in addition
3640 of the internet draft is lib/silccore/silcpacket.h.
3642 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3643 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3644 is used as part of backup router protocol when the primary
3645 router of the cell is back online and wishes to resume
3646 the position as primary router.
3648 * Redefined the MAC generation keys in the protocol. The
3649 same key is not used anymore in both direction. Both
3650 direction will now use different keys for sending and
3651 receiving. This fixes a potential security flaw. This
3652 change causes incompatibilities in the protocol.
3654 * Redefined also the MAC computation from the packet.
3655 An packet sequence number is now added to the MAC
3656 computation. This prevents possible replay attacks against
3657 the protocol. This change too causes incompatibilities
3660 Added `sequence' field to the SilcPacketContext to hold
3661 the current sequence number for the packet.
3663 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3665 * Added `created' field to the SilcIDListData in the file
3666 silcd/idlist.h to indicate the time when the entry was
3669 * Added `created' field to the SilcChannelEntry too. Affected
3670 file silcd/idlist.h.
3672 * Added `creation_time' aguments to all the announcement functions
3673 in the server. If it is provided then only the entries that
3674 was created after the provided time frame are actually
3675 announced. Affected file silcd/server.[ch].
3677 * The protocol says that the Channel ID's IP address must be
3678 based on the router's IP address. Added check for this in
3679 the silc_server_new_channel when processing incoming New Channel
3680 Payload. Affected file silcd/packet_receive.c.
3682 * Print out the correct version with --version in SILC client.
3683 Affected file irssi/src/silc/core/silc-core.c.
3685 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Fixed WHOWAS command to check for completnes of the client
3688 entry always, not just when the command is coming from client.
3689 Affected file silcd/command.c.
3691 * Added new function silc_server_packet_queue_purge to purge the
3692 outgoing data queue to the network. After the function returns
3693 it is guaranteed that the outgoing packet queue is empty.
3694 Affected file silcd/packet_send.[ch].
3696 * Purge the outgoing packet queue in the rekey protocol's final
3697 callback to assure that all rekey packets go to the network
3698 before quitting the protocol. Affected file silcd/server.c.
3700 * Added silc_client_packet_queue_parse as similar function as
3701 in server to the client library. The affected file is
3702 lib/silcclient/client.c.
3704 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Splitted silcd/server.c and created silcd/server_util.[ch]
3707 for utility functions.
3709 * Added new socket flag SILC_SF_DISABLED to indicate that the
3710 connection is open but nothing can be sent to or received from
3711 the connection. Affected file lib/silcutil/silsockconn.[ch].
3712 The checking for disabled socket is checked in the low level
3713 silc_socket_write and silc_socket_read functions.
3715 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Allow only nicknames and channel names that fits into the
3718 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3720 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * When processing JOIN command reply in server check that if
3723 the channel exists in our global list we'll move it the local
3724 list. Affected file silcd/command_reply.c.
3726 * Fixed the check whether client is joined on the channel already
3727 in JOIN command. Affected file lib/silcclient/command.c.
3729 * Fixed the JOIN command reply to check whether the channel
3730 already exists. Affected file lib/silcclient/command_reply.c.
3732 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Added silc_ske_status_string to map the SKE error numbers
3735 to readable strings. The affected files are
3736 lib/silcske/silcske[_status].[ch].
3738 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Do not show the private channels on the WHOIS channel list
3741 as it is not allowed by the protocol. The affected file is
3744 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Assure that the packet length digged from the actual packet
3747 is something sensible in the silc_packet_decrypt_rest_special
3748 in lib/silccrypt/silcpacket.c.
3750 * Free and NULL the allocated pointer in silc_hmac_alloc if
3751 the HMAC allocation fails. The affected file is
3752 lib/silccrypt/silchmac.c.
3754 * Print the selected security properties to the log files in
3755 the server. Affected file silcd/protocol.c.
3757 * Add SKE's reference counter even if calling the completion
3758 callback manually. Otherwise it goes negative, although it
3759 does not cause any problems. The affected file is
3760 lib/silcske/silcske.c.
3762 * Remove the client entry with short timeout after giving the
3763 KILL command. Affected file lib/silcclient/command.c.
3765 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3766 case all found clients are already disconnected (WHOWAS would
3767 found them) in the server. Affected file silcd/command.c.
3769 * Update the last_receive (time of last data received) to be
3770 updated only when received private or channel message so that
3771 the idle time showed in WHOIS makes more sense.
3773 * Added boolean field `valid' in to the SilcClientEntry in the
3774 client library to indicate whether the entry is valid or not.
3775 This fixes the nickname change bug on channel when changing
3776 the nickname to be same than the old (like nick to Nick) the
3777 nickname formatter doesn't set the new nick anymore to Nick@host.
3778 Affected file lib/silcclient/idlist.[ch].
3780 * Now actually fixed the nickname changing on disconnection.
3781 Added new function silc_change_nick to the Irssi SILC Client.
3782 Affected file irssi/src/silc/core/client_ops.c,
3783 irssi/src/silc/core/silc-nicklist.[ch].
3785 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Check that the public key exists in the GETKEY command before
3788 trying to encode it. Affected file silcd/command.c.
3790 * Print some notifications on received public keys with GETKEY
3791 command in the Irssi SILC Client. Affected files are
3792 irssi/src/fe-common/silc/module-formats.[ch],
3793 irssi/src/silc/core/client_ops.c.
3795 * Use IDENTIFY command to resolve the server information in the
3796 GETKEY command instead of INFO command. Affected file
3797 lib/silcclient/command.c.
3799 * All command reply functions in the client library now calls
3800 the pending command reply callbacks even if an error has
3801 occurred. The server has done this a long time and now it was
3802 time to move the client library to this as well. Now all
3803 errors can be delivered back to the pending command reply
3804 callbacks if necessary. Affected files are
3805 lib/silcclient/command[_reply].[ch].
3807 * Change the nickname on disconnection back to the username
3808 because in reconnect the server will enforce it to it anyway.
3809 Affected file irssi/src/silc/core/silc-servers.c.
3811 * Fixed a config file parsing bug in the Irssi SILC client.
3812 Affected file irssi/src/silc/core/clientconfig.c.
3814 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * When printing the channel mode on JOIN, verify that the
3817 channel key and channel's HMAC are valid. Affected file
3818 irssi/src/silc/core/client_ops.c.
3820 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3823 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3824 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3826 * Removed channel key rekey task deleting from the function
3827 silc_server_save_channel_key. Affected file silcd/server.c.
3828 Added explicit timeout task context instead that is used to
3829 delete the task if we are registering a new task before the
3830 new task has elapsed.
3832 * When channel key rekey occurs the client library now saves
3833 the old channel key for a short period of time (10 seconds) and
3834 is able to use it in case some is still sending channel
3835 messages encrypted with the old key after the rekey. Affected
3836 file lib/silcclient/[idlist.h|client_channel.c].
3838 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3840 * Added check to the silc_server_new_id_real to not accept
3841 new ID if it is the sender's own ID. Affected file is
3842 silcd/packet_receive.c.
3844 * Assure that we do not announce ourself or the one we've
3845 sending our announcements when we're router and are announcing
3846 servers to our primary router. Affected file silcd/server.c.
3848 * Fixed silc_server_command_identify_check_client to assemble
3849 correct WHOIS packet. It send corrupted WHOIS packet and
3850 caused problem with router to router connections. Affected
3851 file silcd/command.c.
3853 Fixed also silc_server_command_whois_check the same way
3854 as for the IDENTIFY command.
3856 * Added new SilcIDListStatus to the server in the SilcIDListData
3857 structure. The status now includes the current status of
3858 the entry (like registered, resolved etc.). Affected file
3859 silcd/idlist.[ch]. Defined a bunch of different status types
3860 as well. This replaced the old boolean registered field as well.
3862 Added resolve_cmd_ident field to the SilcClientEntry structure
3863 too so that if the entry is for example being resolved so
3864 another command may attach to the same pending command reply
3865 without requiring to resolve the same entry again. This concept
3866 should optimize the WHOIS and the IDENTIFY resolving under
3867 heavy load by taking away unnecessary resolving for entries
3868 that are being resolved already.
3870 Added support for adding multiple pending commands for one
3871 command idenfier. Affected file silcd/command[_reply].[ch].
3873 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3874 before deleting the data. Otherwise the hash table will have
3875 freed data in comparison functions. Affected file is
3876 silcd/command_reply.c.
3878 * Fixed silc_idlist_replace_client_id to add the new entry to
3879 the cache with NULL nickname. Otherwise there will be invalid
3880 memory as the nickname after the nickname is freed. Affected
3881 file silcd/packet_receive.c.
3883 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3884 saved into wrong slots because the previous number of entries
3885 was not taken into account. Affected file silcd/idlist.c.
3886 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3888 * If we are router and we receive JOIN notify to a channel that
3889 does not have any users then notified client is marked as the
3890 channel founder, as it is it. The affected file is
3891 silcd/packet_receive.c
3893 * Added to the extended hash table API's table_del_*ext functions
3894 the destructor as argument too, so that the caller can decide
3895 which destructor to use or whether to use destructor at all.
3896 Affected file lib/silcutil/silchashtable.[ch].
3898 * Fixed ID Cache purging. It actually deleted the entries from
3899 the hash table after the data was freed. The hash table ended
3900 up comparing freed memory. The affected file is
3901 lib/silccore/silcidcache.c.
3903 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3905 * Fixed Irssi SILC client's KILL command's HELP syntax.
3907 * The USERS command now resolves the detailed user information
3908 if the userinfo field is missing. Affected file is
3909 lib/silcclient/command_reply.c.
3911 * Do not print error in silc_file_read if the read file does
3912 not exist. Just silently return NULL. Affected file is
3913 lib/silcutil/silcutil.c.
3915 * Fixed the silc_log_output to not wine about NULL filename
3916 and to not create some bogus " " filename. Affected file is
3917 lib/silcutil/silclog.c.
3919 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Fixed various printing bugs on the user interface in the
3922 Irssi SILC Client. Minor changes that were forgotten from
3925 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Fixed the configure.in.pre and the compilation and distribution
3928 environment to support the new autoconf 2.52. That version is
3929 now required to compile the CVS trunk.
3931 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3934 to generally parse user@fqdn format strings. Affected file
3935 lib/silcutil/silcutil.c.
3937 * Added nickname_format and nickname_force_format fields to the
3938 SilcClientParams structure. The first one defines the format
3939 for the nicknames that the library will enforce if the receives
3940 multiple same nicknames. The second one is boolean value and
3941 can be used to force the library to always enforce the format
3942 to the nicknames regardles whether there are multiple nicknames
3943 or not. This configurable formatting was employed to flexibly
3944 support accessing multiple nicknames from the user interface.
3945 The userinterface can now set the nicknames to what ever format
3946 they prefer. Affected file lib/silcclient/silcapi.h.
3948 Added function silc_client_nickname_format to the file
3949 lib/silcclient/idlist.c. It performs the nickname formatting.
3951 Added new field `hostname´ to the SilcClientEntry context.
3952 It holds the hostname of the client. Affected file is
3953 lib/silcclient/idlist.h.
3955 * Irssi SILC Client sets the nicknames in nick@hostn format.
3956 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3957 irssi/src/silc/core/silc-core.c.
3959 The WHOIS printing now also shows both the real nickname and
3960 the formatted nickname so that user knows how to access the
3961 user if there are multiple same nicknames cached. Affected
3962 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3963 printing formatting too to take the hostname now as a separate
3964 argument. The Affected file is
3965 irssi/src/fe-common/silc/modules-formats.[ch].
3967 * Changed the silc_client_get_clients_local to accept the formatted
3968 nickname as argument. It accepts the real nickname too but the
3969 formatted nickname can be used to find the true entry from
3970 multiple entries. Affected file lib/silcclient/silcapi.h and
3971 lib/silcclient/idlist.c.
3973 * Added nickname_format_parse field to the SilcClientParams.
3974 It is a callback function provided by the application to parse
3975 the nickname out of the formatted nickname string. The library
3976 calls it to get the nickname from the formatted string. Since
3977 the application generally knows better the format of the nickname
3978 string it parses it instead of the library, even though library
3979 encodes the formatted string. If the callback function is not
3980 provided then the library will use the string as is. The
3981 affected file is lib/silcclient/silcapi.h.
3983 * All the nickname strings passed to the client library in
3984 commands are now expected to be formatted nickname strings.
3985 If the command does not support the formatted nickname string
3986 it will assume that the sent string is the actual nickname.
3987 Affected file lib/silcclient/command.c.
3989 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Added public key authentication support to OPER and SILCOPER
3992 commands in the client library. Affected file is
3993 lib/silcclient/command.c.
3995 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Changed the get_auth_methdod client operation to be asynchronous.
3998 It can be async if the application resolves the authentication
3999 method from the server during the negotiation. Added new
4000 SilcGetAuthMeth completion callback that the application will
4001 call after resolving the authentication method.
4003 Added function silc_client_request_authentication_method that
4004 the application can use to resolve the authentication method
4005 from the server. Added also SilcConnectionAuthRequest callback
4006 that the library will call after the server has replied. The
4007 application can call this function if it does not know the
4008 current authentication method.
4010 Affected files are lib/silcclient/client.c and
4011 lib/silcclient/silcapi.h.
4013 * The Irssi SILC client now automatically resolves the authentication
4014 method incase any configuration information is not present (and
4015 currently there never is). The affected file is
4016 irssi/src/silc/core/client_ops.c.
4018 * Fixed public key authentication from the client library.
4019 Affected file lib/silcclient/protocol.c. Changed also the
4020 protocol specification about the public key authentication in
4021 the connection authentication protocol. The actual data to be
4022 signed is now computed with a hash function before signing.
4024 * Fixed the public key authentication from the server as well.
4025 Affected file silcd/protocol.c.
4027 * Removed the mlock()'s from the memory allocation routines.
4028 Affected file lib/silcutil/silcmemory.c. The ./configure does
4029 not check anymore for the mlock(). Affected file is
4032 * Fixed USERS command in server to allow the execution of the
4033 command for private and secret channels if the client sending
4034 the command is on the channel. Affected file silcd/command.c.
4036 * Fixed silc_client_get_clients_local to return the clients
4037 count correctly. It could return wrong value. Affected file
4038 lib/silcclient/idlist.c.
4040 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4043 types. The assembler optimizations seemed not to like 64-bit
4044 data types. The assmebler optimizations thus are now enabled
4045 also for BSD systems as opposed to only enable them for Linux.
4047 * Do not check for threads at all on BSD systems. Affected
4048 file configure.in.pre.
4050 * Removed -n and -h options from the Irssi SILC Client since
4051 they are not used in silc.
4053 * Fixed the prime generation to assure that the first digit
4054 of the generated random number is not zero since our conversion
4055 routines does not like number strings that starts with zero
4056 digit. If zero digit is seen the random number is regenerated.
4057 This caused some corrupted RSA keys when the zero first digit
4058 was met. Affected file lib/silcmath/silcprimegen.c.
4060 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Fixed WIN32 configuration in the ./configure script.
4063 Fixed to include xti.h on environments that has it.
4064 Patches by Carsten Ilchmann and andrew.
4066 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4068 * Changed the silc_id_create_client_id to be collision
4069 resistant. It is now assured that there cannot be created
4070 two same client ID's. I suspect that some weird bugs in
4071 the server were actually caused by duplicate Client IDs.
4072 Affected file silcd/serverid.[ch]. A router receiving
4073 new ID now also assures and informs the sending server
4074 if the ID caused collision.
4076 * Changed the silc_id_create_channel_id to also assure that
4077 there are no collisions.
4079 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4081 * Statement about ignoring the Mutual Authentication flag when
4082 performing rekey with PFS was a bit misleading. It is ignored
4083 if it was set in the initial negotiation, it cannot be even
4084 set in the rekey. Fixed in the ke-auth draft. Started the
4085 new versions of the protocol drafts in the doc/.
4087 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4089 * Fixed a bug in silc_client_command_identify_save when saving
4090 new channel information. The channel name was no duplicated
4091 and caused crash on exit. Affected file is
4092 lib/silcclient/command_reply.c.
4094 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Fixed the getkey command handling in the server. Send just
4097 empty OK reply to the sender if the key could not be fetched
4098 (but everything else was ok, like the key just was not available).
4099 Changed the public key parameter to optional in the protocol
4100 specs so that empty OK reply can be sent. Affected file
4103 Added a message to Irssi SILC client to tell to user if the
4104 server did not return a public key.
4106 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Fixed a channel key regeneration bug. It registered new
4109 timeout tasks exponentially until all system resources were
4110 used. Affected file silcd/server.c.
4112 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4114 * Added the SILC Document generator to the scripts/silcdoc.
4115 It can be used to generate the Toolkit Reference Manual out
4116 of the source tree. Internally it will also use the RoboDoc
4117 generator now imported in util/robodoc.
4119 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4121 * Added couple of return's in rekey protocol if error orccurred
4122 during the protocol. The execution must be terminated.
4123 Affected file silcd/protocol.c. Also, terminate the protocol
4124 always with timeout.
4126 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4128 * The client's Client ID was created initally from the wrong
4129 nickname (it could have been in format nick@host) in the
4130 silc_server_new_client. Affected file silcd/packet_receive.c
4132 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Added some SILC_LOG_ERROR's to various error conditions
4135 if client could not be added to ID cache. Affected files
4136 silcd/packet_receive.c and silcd/server.c.
4138 * When client's sock->user_data is freed, NULL also the
4139 client->router and client->connection pointers. Added check
4140 for these pointers being NULL to various places around the
4141 code. Affected file silcd/server.c.
4143 * Added client->data.registered == TRUE checks to various
4144 places around the code to assure that unregistered client's
4145 are not handled when it is not allowed. Affected file
4148 * Added `bool registered' fields to all
4149 silc_idlist_[server|client]_get_* routines to indicate whether
4150 the fetched client needs to be registered or not. Affected
4151 file silcd/idlist.[ch].
4153 * Add your own entry as registered to the ID cache in the
4154 server. Affected file server.c.
4156 * Fixed a bug in silc_server_new_server. The SilcServer was
4157 set as the new server's context instead of SilcServerEntry.
4158 This naturally caused some weird bugs.
4160 * Added "updated" field the SilcChannelEntry which indicates
4161 the time since the channel entry was last accessed. This
4162 can be used to determine whether it is necessary to
4163 announce the channel after backup resuming protocol.
4164 Affected files silcd/idlist.[ch].
4166 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4168 * Do not delete the channel rekey task when adding it
4169 for in silc_server_create_channel_key.
4171 * Changed the silc_server_create_channel_key to return
4172 TRUE or FALSE to indicate the success of the channel key
4175 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4177 * Fixed MSVC++ project files and added missing files to
4178 Makefiles under win32/.
4180 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Do not add TCP_NODELAY flag if the operating system
4183 does not have it defined. Affected files are
4184 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4186 * Fixed buffer overflow from Irssi SILC Client. Affected
4187 file irssi/src/fe-common/core/themes.c.
4189 * Fixed double free in client library in the file
4190 lib/silcclient/client.c when disconnecting from server.
4192 * Applied double free patch from cras to Irssi SILC client.
4193 Affected files irssi/src/core/[modules/expandos].c
4195 * Fixed the disconnection handling to Irssi SILC Client.
4196 The application must call silc_client_close_connection
4197 in ops->connect client operation in case of failure of
4198 the connection. Affected file is
4199 irssi/src/silc/core/client_ops.c.
4201 * Do not set sock->protocol to NULL in the function
4202 silc_client_close_connection after executing the protocol's
4203 final callback since the sock might not be valid anymore.
4204 Affected file lib/silcclient/client.c.
4206 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Do not enable SILC_THREADS if the linking with libpthread
4209 did not happen. Affected file configure.in.pre.
4211 * Added notion to protocol specification that server must
4212 verify the sent authentication payload with CMODE when
4213 setting the channel founder key. Implemented it to the
4214 server. Affected file silcd/command.c.
4216 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Added _EXTRA_DIST SILC distribution variable to the
4219 distributions file. It is used to conditionally add extra
4220 files or directories to the specific distribution. Affected
4221 files ./prepare, Makefile.am.pre and distributions.
4223 Removed the `_' from the start of the distribution names.
4226 * Added README.WIN32 for instructions to compile the Toolkit
4229 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4231 * Fixed a double free in disconnection in the server. Affected
4232 file is silcd/server.c.
4234 * Fixed the lib/silcske/groups.c to work now also with GMP
4235 MP library. The string conversion did not work when using
4236 specific base and the base is indicated in the string as well.
4238 * Created win32/ directory which now includes MSVC++ specific
4239 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4240 It will appear only in the toolkit distribution
4242 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4244 * Changed the key material distribution function in case when
4245 the hash output is too short. The data is now concatenated
4246 a bit differently than it used to. Made the change to the
4247 SKE protocol specification.
4249 * Added better GMP detection to configure.in.pre. A patch
4252 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Fixed a minor bug in SKE that might cause some problem on
4255 some platforms. Affected file lib/silcske/silcske.c.
4257 * Added the cookie checking for initiator in the SKE. It checks
4258 that the responder returns the sent cookie unmodified. The
4259 affected file is lib/silcske/silcske.c. Added new SKE
4260 error type INVALID_COOKIE that can be sent during the
4261 negotiation. Fixed some memory leaks as well.
4263 * Added the "invalid cookie" error message to Irssi SILC client's
4266 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4268 * Added `task_max' field to the SilcClientParams to indicate
4269 the maximum tasks the scheduler can handle. If set to zero,
4270 default values are used. Affected file lib/silcclient/silcapi.h.
4272 * Fixed memory leaks in silc_client_close_connection. Affected
4273 file lib/silcclient/client.c.
4275 * Added silc_client_del_client_entry to client library to free
4276 all memory of given client entry. Affected file is
4277 lib/silcclient/idlist.[ch].
4279 * Added new functions silc_client_del_channel and
4280 silc_client_del_server to delete channel and server entries.
4281 Affected file lib/silcclient/[silcapi.h/idlist.c].
4283 * Removed silc_client_del_client_by_id from silcapi.h.
4285 * Fixed the INFO command to return the server's own info
4286 correctly when querying by Server ID. Affected file is
4289 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4291 * Removed the non-blocking settings in WIN32 code in the
4292 silc_sock_[read/write] and added SleepEx instead. Affected
4293 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4294 of input data is now checked with FIONREAD and ioctlsocket.
4296 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4298 * Call silc_schedule_task_del_by_context in the
4299 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4300 Affected file lib/silccore/silcprotocol.c.
4302 * Call silc_protocol_cancel for active protocols in the
4303 silc_server_close_connection if the funtion
4304 silc_server_free_sock_user_data has not been called.
4305 Affected file silcd/server.c.
4307 * Generic tasks cannot be deleted using the del_by_fd
4308 task deleting function since generic tasks does not match
4309 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4311 * Added a notion to SILCOPER help file that the SILCOPER works
4312 only on router server, not on normal server.
4314 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4316 * Added for WIN32 support for the new scheduler as well.
4317 Affected file lib/silcutil/win32/silcwin32schedule.c.
4319 * Fixed the SHA1 implementation to work on various platforms.
4321 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4323 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4324 API. It is part of the scheduler now. Everything else is
4325 as previously but some functions has changed their names.
4326 Checkout the lib/silcutil/silcschedule.h for the interface.
4327 Updated all applications to use the new interface. Affected
4328 files are lib/silcutil/silcschedule.[ch].
4330 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4332 * Found a bug in the SKE implementation. The HASH value,
4333 specified by the protocol, was not computed correctly. The
4334 public key of the responder was not added to the computation
4335 even though it is mandatory. Affected file lib/silcske/silcske.c.
4336 This unfortunately causes incompatibilities with older
4337 clients and servers.
4339 * Added WIN32 specific network init and uninit functions:
4340 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4341 the Winsock2. Affected file lib/silcutil/silcnet.h and
4342 lib/silcutil/win32/silcwin32net.c.
4344 * Set the socket always to nonblocking mode on WIN32 after
4345 reading data or writing data. Affected file is
4346 lib/silcutil/win32/silcwin32sockconn.c.
4348 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Fixed various compilation problems under WIN32. Affected
4351 files lib/silcutil/win32/silcwin32thread.c and
4352 lib/silcutil/win32/silcwin32schedule.c.
4354 * Removed all _internal.h #includes from public header
4355 files. Internal headers must never be included from
4358 Removed also the lib/silcske/payload_internal.h file.
4360 * All include files that may be needed (public and some others
4361 included by the public headers) by application developers are
4362 now copied to the ./includes directory. It does not copy any
4363 internal headers. Affected file Makefile.defines.pre and all
4364 Makefile.am's under lib/ and subdirs.
4366 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4368 * Do not change the ~/.silc directory's permissions automatically.
4369 Affected file irssi/src/silc/core/clientutil.c.
4371 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4373 * Do not cancel the protocol in silc_server_close_connection
4374 it might cause recursion. Now cancelled in the function
4375 silc_server_free_sock_user_data. Affected file silcd/server.c.
4377 * Fixed the silc_server_remove_clients_by_server to regenerate
4378 the channel keys correctly finally. Added also new function
4379 silc_server_remove_clients_channels to actually do it.
4380 Affected file silcd/server.c.
4382 * Fixed the silc_server_new_channel to not crash by giving
4383 wrong router to the new channel. Affected file is
4384 silcd/packet_receive.c.
4386 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4388 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4389 which is given as argument to the silc_client_alloc now.
4390 It can be used to configure the client and set various parameters
4391 that affect the function of the client.
4393 * The USERS command in server did not check whether the channel
4394 is private or secret. Affected file silcd/command.c.
4396 * Added new argument to the USERS command in protocol specification.
4397 The USERS command now can take the channel name as argument
4398 as well. Added support for this in client and server and
4399 updated the protocol specs.
4401 * Completed the GETKEY command in client. It can be now used
4402 to fetch also servers public key not only some clients.
4403 Affected files lib/silcclient/command[_reply].c.
4405 * Added silc_client_get_server to return server entry by the
4406 server name. Affected files lib/silcclient/silcapi.h and
4409 * Redefined the IDENTIFY command in protocol specification to be
4410 more generic. It now can be used to query information about
4411 any entity in the SILC Network, including clients, servers and
4412 channels. The query may be based either the entity's name
4413 or the ID. Added support for this in both client and server.
4415 Affected files silcd/command.c and lib/silcclient/command.c
4416 and command_reply.c.
4418 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4419 the _from_client and _from_server functions. Affected file
4422 * Added silc_client_get_channel_by_id_resolve to the file
4423 lib/silcclient/silcapi.h to resolve channel information by
4424 its ID. Added also silc_client_get_channel_by_id that
4425 does not resolve it from the server.
4427 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4429 * Added SilcServerEntry context into the client library
4430 to represent one server. The INFO command now allocates
4431 these to save the resolved server info. For now on the
4432 client library will also keep information about servers,
4433 connected and resolved with INFO.
4435 The INFO command now allocates the SilcServerEntry context
4436 and saves the server info there. The COMMAND_REPLY in
4437 the INFO now returns the parameters to application in
4438 same order as defined in the protocol specification.
4440 The entries are cached in the client->server_cache.
4442 * The INFO command is now issued after received the Client ID
4443 from the server. Affected file lib/silcclient/client.c.
4445 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4446 to the application as the mode changer might be server.
4447 It is guaranteed that NULL is not returned anymore to the
4448 application. Affected file lib/silcclient/client_notify.c.
4450 The ID Type is now also passed to the application so that
4451 it can check whether the returned entry is SilcClientEntry
4454 Added new function silc_client_get_server_by_id to return
4455 the server entry by ID. Affected files are the
4456 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4458 * Do not create the channel in the Irssi SILC Client when issuing
4459 the JOIN command but when received the sucessful JOIN command
4460 reply. Otherwise the channel might get created even though we
4461 could not join it. The Affected file is
4462 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4464 * Fixed a channel joining bug in router. The router must also
4465 check the channel modes, invite and ban lists etc. when serving
4466 the JOIN command sent by normal server. Affected file is
4467 silcd/command.c. The router now resolves the client's
4468 information from the server who sent the JOIN command if it
4469 does not know it, and processes the JOIN command only after
4472 * Changed the SilcCommandCb to take new argument; void *context2.
4473 Affected file lib/silccore/silccommand.h
4475 The second argument in the command callbacks in the server now
4476 includes the SilcServerCommandReplyContext if the command was
4477 called as pending command callback from the command reply.
4478 Otherwise it is NULL. When called as pending the status of the
4479 command reply will be checked and if it was erronous the
4480 error will be sent to the original sender of the command.
4481 This way the client always receives the error messages even
4482 though the server was actually the one who received the error
4483 when it resent the command to router, for example. Affected
4484 files silcd/command[_reply].[ch].
4486 * Fixed sending WHOWAS command's error message to client if
4487 the requested client could not be found. It was missing.
4490 * Changed the CMODE and CUMODE commands reply arguments in the
4491 protocol specification. The Channel ID is now sent in both
4492 of the commands to identify the channel. Implemented this
4493 new feature to the client and server. Affected files
4494 lib/silcclient/command_reply.c and silcd/command.c.
4496 * Made better checks for invite and ban lists in the JOIN
4497 command in server. Affected file silcd/command.c.
4499 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4501 * The server now performs the incoming host IP/DNS lookup
4502 using the silc_socket_host_lookup and thus does not block
4503 the server anymore. Affected file silcd/server.c.
4505 * Completed the multi-thread support for SILC Scheduler in
4506 the lib/silcutil/silcschedule.c.
4508 * Fixed the configure.in.pre to detect the pthread correctly
4511 * Fixed a deadlock in silc_task_queue_wakeup in the file
4512 lib/silcutil/silctask.c.
4514 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4516 * Added new function silc_schedule_wakeup that is used in
4517 multi-threaded environment to wakeup the main thread's
4518 schduler. It needs to be used when a thread adds a new task
4519 or removes a task from task queues. After waking up, the
4520 scheduler will detect the task queue changes. If threads
4521 support is not compiled in this function has no effect.
4522 Implemented the wakeup mechanism to both Unix and WIN32
4523 systems. Affected files are lib/silcutil/silcschedule.[ch],
4524 lib/silcutil/unix/silcunixschedule.c and the
4525 lib/silcutil/win32/silcwin32schedule.c.
4527 * Added new function silc_task_queue_wakeup to wakeup the
4528 scheduler by the specified task queue. Affected file
4529 lib/silcutil/silctask.[ch].
4531 * The silc_socket_host_lookup_start now wakes up the scheduler
4532 after adding the timeout task. Affected file is
4533 lib/silcutil/silcsockconn.c.
4535 * The silc_socket_host_lookup is synchronous now if the threads
4536 support is not compiled in. However, the callback is still
4537 called asyncronously through the scheduler, anyway. Affected
4538 file lib/silcutil/silcsockconn.c.
4540 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4542 * Added new function silc_socket_host_lookup to perform
4543 asynchronous IP and FQDN lookups for the socket connection.
4544 Affected files lib/silcutil/silcsockconn.[ch].
4546 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4549 that may or may not compile the mutex support in.
4551 Changed the silc_mutex_alloc interface. It allocates the
4552 mutex now to the sent pointer and returns TRUE or FALSE.
4554 Affected file lib/silcutil/silcmutex.h.
4556 * Wrote the SILC Task Queue interface to support multi-threads.
4557 Affected file lib/silcutil/silctask.[ch].
4559 * Wrote the SILC Scheduler to support multi-threads. Affected
4560 file lib/silcutil/silcschedule.c.
4562 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4564 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4565 in lib/silcutil/win32/.
4567 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4569 * Defined SILC Mutex API and SILC Thread API and implemented
4570 them for Unix. Affected files are
4571 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4572 lib/silcutil/unix/silcunixmutex.c and
4573 lib/silcutil/unix/silcunixthread.c.
4575 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4577 * Fixed the silc_server_remove_clients_by_server's channel
4578 key re-generation. The hash table handling was incorrect
4579 and would not work with many channels. Affected file is
4582 * Fixed some memory leaks around the server code.
4584 * Rewrote the silc_server_get_users_on_channel to support IPv6
4585 based Client ID's. Affected file silcd/server.c.
4587 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4588 specification. However, a separate document must be written
4589 to define the detailed signing procedure and the payload
4590 associated with the flag. Defined the flag to the
4591 lib/silccore/silcchannel.h as well.
4593 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4595 * Changed the dynamic tables to static size tables in the
4596 lib/silccrypt/silchmac.c.
4598 * Removed GCC dependencies from the code. A patch by cras.
4600 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4602 * Do not show the error "Error receiving packet bla bla"
4603 in server if it really was not an error (-2 means that reading
4604 is pending). Affected file silcd/server.c.
4606 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4608 * Fixed a possible crash in silc_server_remove_clients_by_server
4609 in silcd/server.c. Fixed there also some memory leaks.
4611 * Fixed the silc_idlist_replace_client_id. It could replace
4612 wrong key in the hash table. Affected file silcd/idlist.c.
4614 * Do not check whether there are global users on the channel
4615 if the channel->global_users is FALSE. Affected functions
4616 silc_server_remove_from_one_channel and
4617 silc_server_remove_from_channels in silcd/server.c. Also,
4618 do not check if the removed client is local as we can be
4619 sure that global client was not removed from the channel
4620 and checking for global users is not needed.
4622 * The silc_server_remove_clients_by_server now re-generates
4623 the channel keys correctly for those channels that had
4624 clients removed from them. Affected file silcd/server.c.
4626 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4628 * Found the reason of random crashes in the server. We weren't
4629 ignoring the SIGPIPE signal (which can be sent in write())
4630 and it crashed the server. Affected file silcd/silcd.c.
4632 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4634 * Assure that sock->user_data is not NULL in the function
4635 silc_server_packet_send in silcd/packet_send.c.
4637 * Disconnect the remote connection if it could not be added
4638 to any ID lists in the server. The affected file is
4641 * Check in silc_server_packet_send[_real/dest] that the
4642 socket is not disconnecting and ignore the data if it is.
4643 Affected file silcd/packet_send.c.
4645 * Define inline to __inline on native WIN32 compilation.
4646 Affected file includes/silcwin32.h.
4648 * Added some explicit type casts for inline code since MSVC
4649 require them. Affected files lib/silcutil/silcbuffer.h,
4650 lib/trq/silcdlist.h and lib/trq/silclist.h.
4652 * Print warning in log files from now on if the packet
4653 decryption fails. Affected file silcd/server.c.
4655 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4657 * Changed the `say' client operation's interface to accept
4658 new `type' argument to indicate the type of the message sent
4659 by the library. The application may filter the library's
4660 messages according the type. The affected file is the
4661 lib/silcclient/silcapi.h.
4663 * Added two new functions to lib/silcclient/silcapi.h:
4664 silc_client_del_client and silc_client_del_client_by_id.
4665 Affected file lib/silcclient/idlist.c.
4667 * Moved the clientincludes.h from includes/ to silc/ and
4668 serverincludes.h from includes/ to silcd/.
4670 * The modes for the CMODE and CUMODE are now passed as
4671 uint32 for application with COMMAND_REPLY. The affected
4672 file is lib/silcclient/command_reply.c.
4674 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4676 * /WHOIS without arguments shows client's own information.
4677 Affected file lib/silcclient/command.c.
4679 * Changed PING to not accept any arguments. The specs
4680 says that client can ping only the connected server so
4681 requiring an argument is not needed. Affected file is
4682 lib/silcclient/command.c.
4684 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4686 * Fixed a fatal bug in private message sending and reception
4687 encryption and decryption when using private message keys.
4688 The implementation was incorrect and did not follow the
4689 specification. It causd that some of the message were
4690 lost since it did not use the sending and receiving keys
4691 as the protocol suggests. This has been fixed and will cause
4692 incompatibilities with older clients when sending private
4693 message encrypted with private message keys. Affected files
4694 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4695 and various other in Irssi SILC Client.
4697 Added `responder' boolean argument to the functions
4698 silc_client_add_private_message_key[_ske] to indicate when
4699 the key is added as responder or initiator of the key
4702 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4704 * Removed the silc_ske_check_version function and created
4705 a SilcSKECheckVersion callback. Added also a function
4706 silc_ske_set_callbacks that is now used to set all SKE
4707 callbacks. The callback functions are not given to
4708 the SKE functions anymore, but this function is used to
4711 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4713 * Added `silc_version' argument to the silc_client_alloc
4714 to define the version of the application for the library.
4715 The library will use the version string to compare it
4716 against the remote host's (usually a server) version
4717 string. Affected file lib/silcclient/silcapi.h
4719 * Added the KE protocol context to Key Agreement context
4720 in client library so that we can abort the SKE if it
4721 is in process when we get timeout. Affected file is
4722 lib/silcclient/client_keyagr.c.
4724 * Do not resolve the client ID forever if it returns in the
4725 first time that such client does not exist. This was done
4726 for example with private message. Affected file is
4727 lib/silcclient/client_prvmsg.c.
4729 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4731 * Do not add regex.h for WIN32. The affected file
4732 includes/silcincludes.h.
4734 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4735 not work yet 100%. It generates the DLL's automatically
4736 when compiling with --with-win32 under cygwin.
4738 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4740 * lib/contrib/regex.c is not compiled on WIN32.
4742 * Added silc_net_get_socket_opt function to the
4743 lib/silcutil/silcnet.h.
4745 * Added includes/silcwin32.h for WIN32 specific includes
4748 * Do not use ptime structure or any of the posix process
4749 functions on WIN32 in lib/silccrypt/silrng.c.
4751 * Added silc_gettimeofday to provide generic function
4752 for struct timeval on all platforms. Added the function
4753 to lib/silcutil/silcutil.h.
4755 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4757 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4758 library as they clearly belong there. As a plus side we
4759 can make the actual socket connection routines platform
4762 Added also new generic function silc_socket_read and
4763 silc_socket_write (that used to be silc_packet_[read/write].
4764 The implementation of these are platform specific.
4766 * Added WIN32 specific routines of silc_socket_[read/write]
4767 to lib/silcutil/win32/silcwin32sockconn.c.
4769 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4771 * Added preliminary support for native WIN32 compilation under
4772 cygwin (using the -mno-cygwin option for GCC) to the
4773 ./configure.in.pre. The --with-win32 now prepares the
4774 compilation for native WIN32.
4776 * Rewrote the SILC Scheduler interface in the file
4777 lib/silcutil/silcschedule.h. The scheduler is now context
4778 based and does not have anymore any global static scheduler.
4779 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4780 and created lib/silcutil/win32 directory for WIN32 based
4783 * Added Unix specific network routines to the
4784 lib/silcutil/unix/silcunixnet.c and the old
4785 lib/silcutil/silcnet.c includes now only generic routines.
4787 Added WIN32 specific network routines to the
4788 lib/silcutil/win32/silcwin32net.c.
4790 * Added Unix specific utility functions from the
4791 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4793 * Added WIN32 SILC Scheduler to the file
4794 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4797 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4799 * Do not handle JOIN notify in the server if the target client
4800 is not registered (idata->registered == FALSE). The affected
4801 file is silcd/packet_receive.c.
4803 * Update the nickrec->founder in event_cumode in the Irssi SILC
4804 client. Affected file irssi/src/silc/core/silc-channels.c.
4806 * Fixed the CUMODE_CHANGE notify handling in the server when
4807 server and router are announcing their clients on channels.
4808 Now the mode changes are saved and notified correctly. The
4809 affected file is /silcd/packet_receive.c.
4811 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4812 They really did not replace the cache entry in the ID Cache.
4813 Now they do that. Affected file silcd/idlist.c.
4815 * Fixed the KICK notify handling in the Irssi SILC client to
4816 update the channel records so that the kicked client does not
4817 appear to be on the channel. The affected file is
4818 irssi/src/silc/core/silc-channels.c.
4820 * Always update the conn->current_channel when executing command
4821 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4823 * Fixed the KILL notify handling in Irssi SILC client to remove
4824 the killed client on all channels.
4826 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Fixed the silc_parse_command_line to remove extra spaces
4829 from the start and end of the arguments. Affected file is
4830 lib/silcutil/silcutil.c.
4832 * Cancel and free any active protocol in the function
4833 silc_server_close_connection. Affected file silcd/server.c.
4835 * Cancel and free any active protocol in the function
4836 silc_client_close_connction. Affected file is
4837 lib/silcclient/client.c.
4839 * Do not execute the KILL command for clients that are in
4840 history (ie. they are not in the network). Affected file is
4843 * Fixed KILL notify handling, client does not crash anymore.
4844 Affected file irssi/src/silc/core/silc-channels.c.
4846 * Reduced the default packet buffer size from 2048 to 1024 in
4847 lib/silccore/silcpacket.c.
4849 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4850 counter to the SKE context that is incresed when the SKE library
4851 performs async operation outside the library. If the outside
4852 process frees the SKE context and FREED status will be set
4853 and the library will detect after the sync operation that the
4854 libary is freed. The affected files are
4855 lib/silcske/silcske[_status].[ch].
4857 * Resolve the client entry information in the function
4858 silc_client_channel_message to assure that NULL pointer is not
4859 passed as client entry to the application. */
4861 * Fixed the task timeout calculation to assure that there is
4862 never negative timeouts. The affected file is
4863 lib/silcutil/silcschedule.c.
4865 * Fixed the channel user mode notification sending in server.
4866 It was sent point-to-point to the router (or to server by router)
4867 but it needs to be destined to a channel. The routines now
4868 supports sending the channel user mode notifys to the channels
4869 when announcing clients and channels. Affected files are
4870 silcd/server.c and silcd/packet_receive.c.
4872 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4873 It did not actually replace the old channel entry in the cache.
4874 Affected file lib/silcclient/client_notify.c.
4876 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Fixed a possible crash in silc_packet_send_prepare. It now
4879 assures always that there is enough space in the buffer and
4880 at the tail area of the buffer (for MAC).
4882 Fixed the inbound buffer reallocation in silc_packet_read.
4883 It was old code and did not handle the reallocation correctly.
4886 The affected file is lib/silccore/silcpacket.c.
4888 * Fixed buffer overflow in silc_parse_nickname in the file
4889 lib/silcutil/silcutil.c.
4891 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * make install generates new server keys only if there is not
4896 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4899 Added check that if the NOREPLY is set then we will not send
4900 the away message. This avoids infinite loop of away messages
4901 if both clients are away. The affected file is
4902 lib/silcclient/client_prvmsg.c.
4904 * Fixed client crash if /NICK was given without arguments.
4905 Affected file lib/silcclient/command.c.
4907 * Server does not send the invite list in INVITE command back
4908 to the client if the list was not altered. Added this notion
4909 to the protocol spec as well. Affected file silcd/command.c.
4911 Fixed possible crash in INVITE command by checking the
4912 value of silc_server_get_client_route command.
4914 * Fixed the INVITE notify type handling. The arguments are now
4915 taken in correct order and client does not crash. The affected
4916 file is irssi/src/silc/core/silc-channels.c.
4918 Removed the "Inviting xxx to channel" message from the
4919 client library away and let the application handle it.
4920 Affected file lib/silcclient/command.c. Added that message
4921 to Irssi SILC client's message formats.
4923 * Fixed CMODE command crash in client. It now checks the
4924 amount of arguments correctly and does not crash. The affected
4925 file is lib/silcclient/command.c.
4927 * Do not create new channel automatically in silc_channels_join
4928 but check whether the channel by that name already exists.
4929 Affected file irssi/silc/core/silc-channels.c.
4931 * Do not send the SERVER_SIGNOFF to router if the disconnected
4932 entity was the router. Affected file silcd/server.c.
4934 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4935 SILC client as it was missing from there.
4937 Added the handling of the KICK notify to the Irssi SILC client
4938 as it was missing. Added "you have been kicked" message to
4939 Irssi SILC client's message modules formats.
4941 Added the handing of the KILL notify to the Irssi SILC client
4942 as it was missing. Added the kill message module formats
4945 The affected file is irssi/src/silc/core/silc-channels.c.
4947 * The router did not save the channel mode the server announced.
4948 Affected file silcd/packet_receive.c.
4950 * Fixed a possible crash in INFO command in server. If the
4951 server did not provide the server info it crashed. Affected
4952 file silcd/command.c.
4954 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Fixed the GETKEY command in the server to check also the
4957 global list. Otherwise the GETKEY would not work correctly
4958 in normal SILC server. Affected file silcd/command.c.
4960 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Fixed GETKEY crash, it crashed if the command did not succseed.
4964 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4967 is now real and not just an macro interface to GMP.
4969 Removed the entire GMP from the source tree and imported new
4970 NSS MPI library instead. Reason for removing GMP is that it is
4971 extremely large and compiles extremely slow. The NSS MPI
4972 is only a few files and compiles in less than 10 seconds.
4973 The speed is also about the same as GMP. The MPI is imported
4974 to lib/silcmath/mpi.
4976 If the system has GMP installed we will still use the GMP.
4977 If it is not then the NSS MPI will be compiled.
4979 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Merged a long nickname (127 characters long) crash bugfix from
4982 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4984 * Merged a freed memory reference bugfix from Irssi CVS tree.
4985 Affected file irssi/src/core/commands.c.
4987 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Added the server's public key sving and verification to the
4990 server when performing the SKE. This was missing and the
4991 remote server's (or router's) public key was accepted without
4992 checking whether we have it previously or trust it at all.
4993 Affected file silcd/protocol.c.
4995 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Check in the silc_server_timeout_remote if protocol is active
4998 and make sure that the protocol's final callback is called so
4999 that all memory if freed. Affected file silcd/server.c.
5001 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * silc_server_whois_send_reply crashed the server if the nickname
5004 was 127 characters long. Affected file silcd/command.c.
5006 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added sanity check to the silc_server_new_client. If the hostname
5009 is provided inside username then check that the provided hostname
5010 really is the same as the resolved one. If the hostname was not
5011 resolved then check it from the public key. Affected file is
5012 silcd/packet_receive.c.
5014 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5015 if the server disconnected us and the connection is not valid
5016 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5018 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5019 the library to the lib/silcutil/silcutil.[ch].
5021 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Close log file after open. Affected file
5024 lib/silcutil/silclog.c.
5026 * Check whether sock == NULL in silc_client_send_packet and return
5027 if it is. Affected file lib/silcclient/silcclient.c.
5029 * Check rec->entry == NULL in the Irssi SILC Client before
5030 sending the channel message. Affecte file is
5031 irssi/src/silc/core/silc-servers.c.
5033 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Merged a splitted window bugfix from Irssi CVS tree. The
5036 affected file is irssi/src/fe-text/textbuffer-view.c.
5038 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5039 It did not print nickname.
5041 * Improved the distributions system a bit.
5043 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5046 irssi/src/fe-text/gui-window.c.
5048 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5049 to in-active server. The affected file is
5050 irssi/src/silc/core/client_ops.c.
5052 * Resolve the client in USERS command reply if the entry does
5053 not have username resolved. The affected file is
5054 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5055 command to WHOIS command to really resolve stuff. The USERS
5056 is not used any more in any critical section so WHOIS can
5057 be used even though it might be slower than IDENTIFY.
5059 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5062 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Changed the protocol API a bit more consistent in the
5065 lib/silccore/silcprotocol.[ch].
5067 * Changed the following headers to ROBODoc format:
5069 lib/silccore/silcpayload.h
5070 lib/silccore/silcprotocol.h
5071 lib/silccore/silcsockconn.h
5073 All core library headers are now formatted.
5075 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Fixed a bug in Irssi SILC client; do not show that you are
5078 server/router operator if you really are not. Affected file is
5079 irssi/src/silc/core/client_ops.c.
5081 * Renamed silc_command_free_payload to silc_command_payload_free.
5082 Affected file lib/silccore/silccommand.h
5084 * Added silcmath.h to include the prototoypes of various routines
5085 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5088 * Changed the following headers to ROBODoc format:
5090 lib/silccore/silcchannel.h
5091 lib/silccore/silccommand.h
5092 lib/silccore/silcid.h
5093 lib/silccore/silcidcache.h
5094 lib/silccore/silcmode.h
5095 lib/silccore/silcnotify.h
5096 lib/silccore/silcpacket.h
5097 lib/silcmath/silcmath.h
5099 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Added checking to the server code not to start the server if
5102 ciphers and stuff are not configured properly. Affected files
5103 silcd/serverconfig.[h] and silcd/server.c.
5105 * Changed the layout of the header files of the public interfaces
5106 in the SILC libraries. The new layout supports ROBODoc
5107 documentation tool (and some others) so that it is easy to create
5108 a library reference manual. All the other headers and source
5109 code must still follow the CodingStyle document. Also source
5110 code must not include these ROBODoc stuffs, only the headers.
5111 Furthermore, all public interface headers must now be named
5112 by using `silc' prefix, example: silcapi.h, silccipher.h.
5113 Some files were renamed due to this. All the other headers
5114 must not be used as public interfaces. I will update the
5115 CodingStyle document later. Changed following headers, so far:
5117 lib/silcclient/silcapi.h
5118 lib/silccore/silcauth.h
5119 lib/silccore/silcprivate.h
5120 lib/silccrypt/silcdh.h
5122 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Removed silc_client_packet_send_flush from the client library
5127 as it is not needed. Affected file lib/silcclient/client.[ch].
5129 * Added printing of message of unresolved authentication method
5130 to the Irssi SILC client. Added it to the module formats.
5131 Removed the same message from the client library.
5133 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added new distribution feature, DISTLABEL. Every distribution
5136 can define own preprocessor label that can be used in the
5137 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5138 file distributions, acconfig.h.pre and prepare.
5140 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Added Makefile.defines_int to include the actual definitions
5143 for Makefile.defines.in. Tested the new distribution system,
5144 created distributions and tested installation.
5146 * Added AWAY message printing to the Irssi SILC client. Added
5147 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5149 * Added SCONNECT command to call the SILC's CONNECT command.
5150 Cannot use CONNECT directly since Irssi uses that internally.
5151 Affected file irssi/src/silc/core/silc-servers.c.
5153 Added ACTION local command. It is same as ME command but takes
5154 the channel as mandatory argument.
5156 Rewrote some of the Irssi's help files to suite for SILC
5159 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Added Makefile.defines[.in] that should for now on be included
5162 in all Makefile.am file in the source tree. That file includes
5163 all common compilation definitions for SILC source tree.
5165 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Minor changes to the ./prepare script to change the package
5168 name according the distribution name to the configure.in.
5170 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Created new distribution system. Added file `distributions'
5173 that defines all the distributions that can be created out of
5174 the SILC source tree. The ./prepare script now reads that
5175 file to determine how to prepare the distributions. The
5176 first argument to the ./prepare is the name of the distribution
5177 and second is the version of the distribution. If given
5178 without arguments it creates the default (toolkit) distribution
5179 with the default version (defined in ./prepare).
5181 All Makefile.am files that are subject to the distributions
5182 are now named as Makefile.am.pre. These are ./Makefile.am
5183 and lib/Makefile.am. Others may be changed later.
5185 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * Added invite list, ban list, some key management and connection
5188 error message printing to module formats in the Irssi SILC client.
5190 * Added new silc_client_set_away_message to set the away message
5191 that is back to the person who sent private message. The
5192 affected file lib/silcclient/silcapi.h and the
5193 lib/silcclient/client_prvmsg.c.
5195 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Fixed the private message sending in the Irssi SILC client,
5198 added local command KEY to the Irssi SILC client.
5200 Added key management and key agreement message formats to the
5201 irssi/src/fe-common/silc/module-formats.[ch].
5203 Added USERS (alias WHO) printing, server/router operator
5204 indication and LIST command printing to the module formats.
5206 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Fixed channel joining notify handling, cumode notify handling
5209 from Irssi SILC client.
5211 * Added SILC specific module-formats to the Irssi SILC client so
5212 that SILC specific message hilighting, colors etc is possible.
5213 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5215 Added channel mode, channel user mode, actions, notices,
5216 whois and whowas printing to the the module-formats.c.
5218 * Fixed a bug in channel deletion in the server. The channel
5219 is not left to the cache even if the channel founder auth mode
5220 is set when there are no users anymore on the channel. Affected
5221 file silcd/server.c.
5223 * The silc_net_localhost now resolves the entire hostname including
5224 the domain name. Affected file lib/silcutil/silcnet.c.
5226 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Changed the ask_passphrase client operation to be ascynchronous.
5229 It has now a completion callback and a context that the
5230 application must call after it has got the passphrase from
5231 the user. Affected files lib/silcclient/silcapi.h,
5232 lib/silcclient/protocol.c, lib/silcclient/command.c and
5235 Added SilcAskPassphrase callback that the application calls
5236 to deliver the passphrase to the library.
5238 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5239 The public key verification and especially a certificate
5240 verification is asynchronous procedure.
5242 Added new SILC_SKE_STATUS_PENDING status to indicate the
5243 request is pending and a callback will be called to finalize
5246 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5247 indicate that remote end did not send its public key (or
5248 certificate), even though we require it. Added check for this
5249 condition in the SKE. This was a security bug, now fixed.
5251 Defined new SilcSKEVerifyCbCompletion callback that is called
5252 when the verification process is completed.
5254 The affected files lib/silcske/silcske_status.h and
5255 lib/silcske/silcske.[ch].
5257 * Changed the verify_public_key client operation to be async
5258 as well. Defined SilcVerifyPublicKey callback that is used to
5259 indicate the success of the public key verification process.
5261 Changed the server and client to use the new async client
5264 * Changed the Irssi SILC client's internal scheduler to be called
5265 twice as many times as it used to be. As a result the client
5266 should be a bit faster now. Affected file is
5267 irssi/src/silc/core/silc-core.c.
5269 * Added support to Irssi SILC client of asynchronous public key
5270 verification and passphrase inquiry. Affected file is
5271 irssi/src/silc/core/silc-core.c.
5273 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Do not say "You have left channel %s" in client library.
5276 Moved it to the application. Affected files are
5277 lib/silcclient/command.c and silc/client_ops.c.
5279 * Fixed silc_client_get_clients. Command context was not
5280 duplicated and was freed memory in the callback. Affected
5281 file lib/silcclient/idlist.c.
5283 * Do not say "you are now talking..." on JOIN command in the
5284 client library. The appliation must handle it.
5286 * Do not say ".. changed topic to" in command reply in the
5287 client libary. The application must handle it.
5289 * Fixed TOPIC command sending in the client library.
5291 * Fixed a memory leak in silc_client_command_free in the file
5292 lib/silcclient/command.c.
5294 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Imported a modified version of Irssi client to the source tree.
5297 The Irssi will be used to create a new client called
5298 Irssi SILC. Imported to irssi/.
5300 Added silc_core_init_finish function to the Irssi. Affected
5301 file irssi/configure.in.
5303 A lot changes in the Makefile.ams around the irssi tree.
5305 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Do not rehash if the new size is same as the old size of the
5308 hash table, in the silc_hash_table_rehash*. The affected file
5309 lib/silcutil/silchashtable.c.
5311 * Replaced hash_table_del_by_context calls from the server
5312 (when channel->user_list and client->channels) to the
5313 hash_table_del as it is sufficient and faster.
5315 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Added silc_hash_table_list, silc_hash_table_get and the
5318 SilcHashTableList structure to provide an alternative way to
5319 traverse the hash table. The affected files are
5320 lib/silcutil/silchashtable.[ch].
5322 * Changed the server's idlist routines to use the hash table
5323 routines to optimize the code.
5325 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Replaced the client entry's `channel' list and channel entry's
5328 `user_list' list to hash tables for optimized lookup. Changed
5329 the code to use the hash table interface around the code.
5330 Affected file lib/silcd/idlist.[ch].
5332 * Added `auto_rehash' boolean argument to the function
5333 silc_hash_table_alloc to indicate whether the hash table should
5334 auto-rehash when it thinks is appropriate time. It will
5335 increase the hash table size if the there is twice as much
5336 entries in the table than the size of the table, and will
5337 decrease the size if there are twice as less entries than
5338 the size of the table.
5340 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5344 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * silc_idcache_purge_by_context deletes the entry now by context
5347 as it is supposed to do. Affected file lib/silccore/idcache.c.
5349 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5350 client is not anymore valid (WHOWAS givens the info) and not
5351 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5353 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Removed the `data' and `data_len' arguments from the ID Cache
5356 interfaces and added `name' argument. ID Cache does not handle
5357 anymore the binary data only a names associated with given ID.
5359 * When hashing a Client ID with silc_hash_id the entire ID is
5360 not hashed anymore, instead only the hash of the Client ID is
5361 hashed. This way we can access the Client ID from the cache
5362 with Client ID but with the hash of the ID (which is a hash of
5363 the nickname) as well without any difference in performance.
5365 Added also silc_idcache_find_by_id_one_ext to do one on one
5366 searching when we have the actual ID. Added also function
5367 silc_hash_client_id_compare. The affected files are
5368 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5370 * When hashing the name associated with a ID it is always done
5371 in lowercase. This way we can access the cache without worrying
5372 about case-sensitivity, even though, for example nicknames are
5375 * Fixed a bug in server with channel message sending. It put
5376 wrong ID type as destination ID. The affected file
5377 silcd/packet_send.c.
5379 * silc_idcache_del_by_context now deletes from all hash tables
5380 by context. Affected file lib/silccore/idcache.c.
5382 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Changed the client library to use the new ID Cache interface.
5385 Changes around the source tree.
5387 * Added silc_hash_table_rehash_ext to rehash with specific
5388 hash function. Affected file lib/silcutil/silchashtable.[ch].
5390 * Added silc_hash_string_compare to compare two strings in the
5391 hash table. Affected file lib/silcutil/silcutil.[ch].
5393 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Added new function silc_idcache_del_by_context into the
5396 lib/silccore/idcache.[ch].
5398 * Changed the server's ID list routines to use the new ID Cache
5399 interface. Changes around the source tree.
5401 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Added silc_hash_table_del[_by_context]_ext functions in to the
5404 lib/silcutil/silchashtable.[ch].
5406 Removed silc_hash_table_find_all* routines and added new
5407 silc_hash_table_find_foreach to replace them.
5409 Added silc_hash_table_replace_ext function as extended
5410 replacing function. Separated the simple hash table interface
5411 from the extended hash table interface in the file
5412 lib/silcutil/silchashtable.h.
5414 * Fixed minor bugs and changed it to use some of the new
5415 hash table functions in lib/silccore/idcache.c
5417 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Added new function silc_hash_table_find_all to return all keys
5420 in the hash table by the specified key. As the hash table is
5421 collision resistant it also makes it possible to have several
5422 duplicate keys in the hash table. This function may be used to
5423 find all of the keys from the hash.
5425 Added user_context arguments to the SilcHashFunction,
5426 SilcHashCompare and SilcHashDestructor to deliver user specified
5429 Added new fuctions silc_hash_table_find[_all]_ext to do
5430 extended lookup with specified hash and compare functions and
5431 specified user contexts.
5433 Added new function silc_hash_table_add_ext to add the key
5434 with specified hash function and user context.
5436 Added new function silc_hash_table_foreach to traverse all
5437 entrys in the hash table. Added SilcHashForeach callback
5440 Added new function silc_hash_table_del_by_context to delete
5441 the entry only if the context associated with the key matches.
5443 Affected files are lib/silcutil/silchashtable.[ch].
5445 * Removed silc_hash_[server/client/channel]_id and added just
5446 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5447 silc_hash_id_compare to compare two ID's using as the hash table
5448 comparison function. Added also silc_hash_data to hash
5449 binary data and silc_hash_data_compare to compare it.
5451 * Removed silc_idlist_find_client_by_hash as it is not needed
5452 anymore. Affected file silcd/idlist.[ch].
5454 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5455 to use internally the SilcHashTable. The new ID Cache is a lot
5456 faster than the old one. Some of the ID Cache interface was also
5457 rewritten and obsolete and stupid functions were removed.
5459 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Added entry_count field to the SilcHashTable to keep the number
5462 of the entries in the table. Implemented the function
5463 silc_hash_table_rehash. Added new function
5464 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5466 Fixed a minor bug in silc_hash_table_free.
5468 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5469 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5470 into the lib/silcutil/silcutil.[ch].
5472 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Implemented a collision resistant hash table into the
5475 lib/silcutil/silchashtable[ch]. See the header and the source
5476 for the SilcHashTable API.
5478 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Merged dotconf version 1.0.2 into lib/dotconf.
5482 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Do not compile anything in lib/silcsim/* if the SIM support
5485 is not enabled. The tree should now compile without problems
5488 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Compiled the SILC under cygwin. Compiled and tested briefly
5491 without problems. More tests needed. The SIMs didn't compile
5494 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5496 * Fixed possible crash in silc_get_username in the
5497 lib/silcutil/silcutil.c.
5499 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Fixed a va_arg in silc/client_ops.c.
5503 * Oops, RC5 routines were named AES and caused some problems
5504 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5506 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Added new SilcIDIP structure into the lib/silccore/id.h and
5509 replaced the old `ip' fields from all SILC ID's to that type.
5510 This is a step towards IPv6 support.
5512 The silc_id_get_len takes now the ID as an extra argument.
5513 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5514 both IPv4 and IPv6 based ID's.
5516 The affected files are lib/silccore/id.[ch] and other files
5517 around the tree using these routines.
5519 * Removed the ID length arguments in server from various
5520 silc_server_send_notify_* routines -> they are not needed
5523 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Fixed memory leak in silc_encode_pem_file in the file
5526 lib/silcutil/silcutil.c.
5528 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Check minor version as well in the SKE. Affected files are
5531 silcd/protocol.c and lib/silcclient/protocol.c.
5533 * Added --identifier option to the server so that an identifier
5534 can be when creating the public key for the server. Affected
5535 file is silcd/silcd.c.
5537 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5538 lib/silccrypt/silcpkcs.c.
5540 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Register default ciphers and stuff when using -C option with
5543 the server. Affected file sildc/silcd.c.
5545 * Put back the servers public key filename format, it is better
5546 than the new one. For now, the client keys are saved with the
5547 new filename format. The affected file silc/client_ops.c.
5549 * Implemented the Cipher API for the rest of the ciphers that
5550 did not implement it or implemented it the wrong way.
5552 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Register default ciphers and stuff when using the -S option
5555 in the client. Affected file silc/silc.c. Same also when
5556 creating new key pair with -C option.
5558 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Fixed the silc_verify_public_key client operation function to
5561 save the public keys differently. The fingerprint is now
5562 used as filename and not the hostname. This way also the
5563 client keys are saved uniquely and not with hostnames. The
5564 affected file is silc/client_ops.c.
5566 * Trimmed the silc_hash_fingerprint function to remove extra
5567 whitespaces from the end of the fingerprint. The affected
5568 file is lib/silccrypt/silchash.c.
5572 * Added silc_cipher_register_default function to register all
5573 default ciphers. It can be used when configuration files
5574 does not exist and the application does not want any specific
5575 ciphers in any specific order.
5577 The SilcDList is now used as silc_cipher_list dynamically
5578 allocated cipher list. Removed the static list all together
5579 and now all ciphers must be allocated to the dynamic list.
5580 The silc_cipher_alloc routine was changed to check only the
5583 All silc_cipher_* routines that used to return int returns
5586 The affected files lib/silccrypt/silccrypt.[ch].
5588 * The same thing was done to silc_hash_* as for silc_cipher_*
5589 routines. Affected files lib/silccrypt/silchash.[ch].
5591 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5592 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5593 Added also silc_pkcs_[un]register[_default] functions.
5594 Removed the data_context from the PKCS API.
5596 * Added silc_hmac_register_default function to register default
5597 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5598 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5599 to unregister all hmacs at once.
5601 * Register the default ciphers, hash functions, PKCSs and HMACs
5602 if client's configuration file does not exist. The affected
5605 * The client did not load the hash functions from the SIM
5606 modules at all. Added support for this. Affected file is
5607 silc/clientconfig.c.
5609 * When decoding public key with silc_pkcs_public_key_decode, check
5610 the supported algorithm only if PKCS are registered. Affected
5611 file lib/silccrypt/silcpkcs.c. The same was done with the
5612 silc_pkcs_private_key_decode.
5614 * Fixed the SILC List routines to keep the list always in order.
5615 It used to change the list's order when traversing the list but
5616 not it preserves the order. Affected file lib/trq/silclist.h.
5618 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added the client library to use the SilcSocketConnection's
5621 reference counter (by silc_socket_dup) to prevent the bug that
5622 the socket object may be freed underneath async operation.
5624 * The name resolv library checking fixes in the configure.in.pre.
5627 * Created new version of the protocol drafts for future
5628 development. The -03 drafts are the ones that will be changed
5629 in the trunk now and the -02 will remain as they are.
5631 * Send list of CUMODE notifys to the router when announcing
5632 the channel users to the router. Affected file silcd/server.c.
5633 If the router receiving channel founder CUMODE for a channel
5634 that already has channel founder it will send CUMODE notify
5635 to the sender to remove the channel founder rights from the
5636 announced client. Affected file silcd/packet_receive.c.
5638 * The CUMODE notify may now use Server ID as well as the entity
5639 who changes the mode. Updated protocool specs.
5641 * Updated INSTALL and README files.
5643 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * New web pages in the http://silc.pspt.fi. The pages was
5650 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Implemented the [DenyConnectin] config section in the server.
5653 Added silc_server_config_denied_conn to check whether incoming
5654 connection is denied. Affected file silcd/serverconfig.[ch].
5656 * Do not check the ports when checking the incoming configuration
5657 data if the port is 0, meaning any. Affected file is
5658 silcd/serverconfig.c.
5660 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Fixed buffer overflow in silc_string_compare in the file
5663 lib/silcutil/silcutil.c.
5665 * Fixed double free in silc_server_command_leave in the file
5668 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Fixed the version checking in the server. Affected file is
5673 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Fixed the configuration data fetching when accepting new
5676 connections in the server. Affected file silcd/server.c.
5678 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Added `sender_entry' argument to the function
5681 silc_server_packet_relay_to_channel so that we can check
5682 whether some destination actually belongs to the same route
5683 the sender belongs (ie, we must not resend the packet to the
5684 sender). Affected file silcd/packet_send.[ch].
5686 * Added `servername' field to the SilcClientEntry in the server
5687 to hold the name of the server where client is from. Affected
5688 file is silcd/idlist.h.
5690 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Moved the channel message encrypting in the router betwen
5693 router connections from silc_server_channel_message to the
5694 silc_server_packet_relay_to_channel since we want to check
5695 whether we have anybody channel before encrypting anything.
5696 Affected files silcd/packet_[receive/send].c.
5698 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Fixed the [AdminConnection] server config section to support
5701 multiple entries. Affected file silcd/serverconfig.c.
5703 * Added support into the server to check the validity of the
5704 incoming connection before executing any KE or authentication
5707 * The connection configuration is now saved to the KE and
5708 connection auth protocol contexts and not fetched anymore in
5709 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5711 * The local hosts listenning address and port is also resolved
5712 now when starting the server. We want to have the socket object
5713 to include the real address and port for the listener. Added
5714 new function silc_net_check_local_by_sock into the files
5715 lib/silcutil/silcnet.[ch].
5717 * Fixed a broadcast bug in server -> do not broadcast if we
5720 * Fixed a routing bug. Do not route broadcast packets ever.
5721 Broadcast packets must be processed always and not routed since
5722 they may be destined to some other host than yourself and thus
5723 would get routed without no good reason. Affected file is
5726 * Added function silc_server_config_is_primary_route to check
5727 whether primary router connection has been configured (a router
5728 configuration that we are initiating). If there is not, we
5729 will assume that there is only two routers in the SILC network
5730 and we will use the incoming router connection as our primary
5731 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5733 * Changed the order of the broadcasting. Broadcast _after_ the
5734 packet has been processed not before. Affected file is
5737 * Fixed a [ClientConnection] parsing bug. The port was never
5738 parsed correctly thus resulting to port 0. Affected file
5739 silcd/serverconfig.c.
5741 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5742 argument and did not set the broadcast packet flag. Affected
5743 file silcd/packet_send.c. Fixed same bug in the function
5744 silc_server_send_notify as well.
5746 * If we receive NEW_ID packet for our own ID in the server, ignore
5749 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Removed the nickname from the Private Message Payload.
5754 Updated the code and the protocol specs.
5756 * Updated protocol specs for submitting to the IETF.
5758 * Tweaked the Random Number Generator a bit. Affected file
5759 lib/silccrypt/silcrng.c. Exported a new function
5760 silc_rng_[global]_add_noise which can be used to add more
5763 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Do not parse packets with different timeout when protocol
5766 is active -> may cause problem with rekey. Affected file
5769 * When server receives signoff notify it must not create
5770 new channel key if the client is on any channels since the
5771 sender of the signoff notify will create it.
5773 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Added printing of error messages during SKE protocol from the
5776 failure packet sent by server during SKE. Affected file
5779 * Removed the client's failure_callback handling with timeout
5780 and handle it immediately when received.
5782 * The SKE library returned wrong type in SUCCESS and FAILURE
5783 packets. They must be 32 bit MSB not 16 bit MSB.
5785 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Ok, rewrote the logic of the re-key and now it seems to work.
5788 I tested it on high traffic with frequent re-keys without
5789 problems. Added hmac_receive (and renamed hmac to hmac_send)
5790 in SilcClientConnection in lib/silcclient/client.h and
5791 in SilcIDListData in silcd/idlist.h. Also, removed the
5792 SilcPacketParserContext's cipher and hmac fields as they are
5793 not needed anymore and actually caused some problems when
5794 the ciphers and hmac's changed underneath the packet parser.
5796 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * If re-key protocol is active then process the incoming packets
5799 synchronously since we must assure that icoming packets encrypted
5800 with the old key is processed before the new keys is set to
5801 use. This is true other packets than for REKEY packets.
5802 Affected file silcd/server.c. The same was done to client library
5803 as well, affected file lib/silcclient/client.c.
5805 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Fixed bug in client and server to accept the force send if
5808 the packet is send from silc_[server/client]_packet_process
5809 function. Otherwise the packets are never delivered, oops.
5811 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Disable force sending of packets when REKEY protocol is active.
5814 We must assure that no packet is sent directly when rekey is
5815 performed. All packets must be sent through packet queue.
5816 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5817 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5818 function is silc_[server/client]_packet_send_real to check
5821 * Replaced the SIM paths from example config files to
5822 /usr/local/modules. Also, make install creates now
5823 /usr/local/silc/logs directory to hold all the SILC server
5826 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Made the configure.in.pre work on Solaris. Patch by salo.
5830 * Made all ciphers compatible with non-x86 machines. Defined
5831 CBC mode macros into lib/silccrypt/ciphers_def.h.
5833 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Fixed the make install.
5837 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * When MAC computation fails the silc_packet_decrypt returned 0
5840 even though it was supposed to return -1. Fixed this. The
5841 affected file is lib/silccore/silcpacket.c.
5843 * Do not replace the config files in /etc/silc (in make install)
5844 if they already exist. Affected file ./Makefile.am.
5846 * Do not send re-key packets immediately but through packet queue.
5847 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5849 * Changed silc_net_check_host_by_sock to return FALSE if the
5850 IP/DNS could not be resolved. Though, it returns the IP address
5851 now even if it could not resolve it (but returns also FALSE).
5852 Affected file lib/silcutil/silcnet.[ch].
5854 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Added silc_pkcs_decode_identifier to decode the public key's
5857 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5858 Added also silc_pkcs_free_identifier. Added also new context
5859 SilcPublicKeyIdentifier.
5861 * Added -S option to the silc client. It is used to dump the
5862 contents of the specified public key file.
5864 * Changed the PKCS api to return the public key length when
5865 setting the public key.
5867 * Fixed a fatal bug in the public and private key file loading.
5868 Affected file lib/silccrypt/silcpkcs.c.
5870 * Execute the packet parsing for client with zero (0) timeout
5871 if the protocol is active. Affected file silcd/server.c.
5873 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Made the key generation options to the silcd program. Added
5876 -C option, equivalent to client's option.
5878 * Added new [ServerKeys] config section to the server. It
5879 configures the server's public and private key.
5881 * Defined generic Public Key Payload into the protocol
5882 specification to send specific type of public keys and
5885 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5886 public key or certificate.
5888 * Implemented the GETKEY command to the server and to the
5889 client library and on user interface.
5891 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Made preliminary `make install' work.
5895 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Added SilcServerRekey context into silcd/idlist.h.
5899 * Added the PFS support as defined in the specification to the
5900 SKE protocol. Affected files lib/silcske/*.c.
5902 * Added `ske_group' field to the SilcServerRekey context to hold
5903 the number of the SKE group that is used with PFS in re-key.
5904 Affected file silcd/idlist.h.
5906 * Added PFS re-key support to the server. Affected file is
5909 * Added silc_protocol_cancel to cancel execution of the next
5910 state of the protocol. Affected file is
5911 lib/silccore/silcprotocol.[ch].
5913 * Added the re-key support with and without PFS to the client
5914 library. Re-key is performed once in an hour, by default.
5916 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5917 Added silc_client_rekey_callback and silc_client_rekey_final.
5918 Affected files are lib/silcclient/protocol.[ch] and
5919 lib/silcclient/client.[ch].
5921 * Removed the `hmac_key' and `hmac_key_len' fields from the
5922 SilcClientConnection structure; not needed. Affected file is
5923 lib/silcclient/client.h.
5927 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Do not ask whether user wants to use the negotiated private key
5930 for private messages, just use it. Affected file is
5931 silc/local_command.c.
5933 * Added `send_enc_key' and `enc_key_len' fields to the
5934 SilcIDListData structure since they are needed in the re-key
5935 phase. Affected file is silcd/idlist.[ch].
5937 * Implemented the simple re-key protocol into the server.
5938 Affected files silcd/server.c and silcd/protocol.[ch]. The
5939 re-key will be performed once in an hour, by default.
5941 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5942 Added silc_server_rekey, silc_server_rekey_callback and
5943 silc_server_rekey_final.
5945 * Removed Tunneled flag from the protocol. Updated the code
5946 and the specifications.
5948 * Adde `pfs' field to the SilcIDListData to indicate whether
5949 the PFS is to be performed in the re-key. Affected file is
5952 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5955 int64 of at least the xintXX size. If void * is less that 4
5956 bytes uint32 * will be used. Defined bool as boolean.
5958 * Changed _ALL_ unsigned long and unsigned int to uint32,
5959 unsgined short to uint16 in the source tree.
5961 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5962 not handle clients that has entry->data.registered == FALSE.
5963 They are not in the network anymore. Affected file is
5966 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Implemented the sending of the SERVER_SIGNOFF notify in the
5969 server. Affected file is silcd/server.c.
5971 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5972 Added also silc_notify_payload_encode_args into the
5973 lib/silccore/silcnotify.[ch].
5975 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5976 Affected file silcd/packet_receive.c.
5978 * Implemented the SERVER_SIGNOFF notify handling in the client
5979 library. Affected file lib/silcclient/client_notify.c. Also,
5980 implemnted the printing of the SERVER_SIGNOFF info to the
5981 application. Affected file silc/client_ops.c.
5983 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5984 if the deleting was successful. Affected file silcd/idlist.[ch].
5986 * Added support for public key authentication in the connection
5987 authentication protocol in the client library. Affected file
5988 lib/silcclient/protocol.c.
5990 * Changed the server's silc_idlist_get_clients_by_* interface
5991 to support already allocated array so that new entries may be
5992 added to pre-allocated array. Affected file silcd/idlist.[ch].
5993 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5994 and command replies.
5996 * All command reply functions in the server now calls the
5997 pending command callback even if error occured. This way the
5998 error will be delivered to the client as well. Affected files
5999 silcd/command.c and silcd/command_reply.c.
6001 * Fixed INFO command to return local server's info if no server
6002 was provided. Affected file lib/silcclient/command.c.
6004 * Removed RESTART command for good. Updated the code and the
6007 * Rewrote parts of the task system. It is a bit simpler now.
6008 Removed unsued task priorities. The affected files are
6009 lib/silcutil/silctask.[ch].
6011 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Moved the USERS printing from the library to the application.
6014 Affected files lib/silcclient/command.c and silc/client_ops.c.
6016 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Added channel key re-key support. The re-key is perfomed
6021 only by the router and is done once in an hour. Added `rekey'
6022 field to the SilcChannelEntry in the server. Affected files
6023 silcd/server.c and silcd/idlist.h.
6025 * Added silc_task_unregister_by_context into the file
6026 lib/silcutil/silctask.[ch].
6028 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Added SILC_UMODE_GONE mode to indicate when the client is not
6031 present in the SILC network. Added also support to the local
6032 command AWAY that will set this mode. Added support of showing
6033 "xxx is gone" in WHOIS command. The USERS command shows the
6034 gone status as well.
6036 * Fixed setting server and router operator privileges in the
6037 server's UMODE command. Affected file silcd/command.c.
6039 * Merged the SKE KE1 and KE2 payloads into one payload. The
6040 new KE payload is equivalent to the old KE2 payload.
6042 Cleaned up the SKE Start Payload parsing. It now uses the
6043 simple buffer unformatting to do the parsing. A lot faster
6046 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6047 to the SKE that is used to indicate whether both of the SKE
6048 parties should perform authentication. By default only the
6049 responder performs authentication. By setting this flag also
6050 the initiator must do authentication. By default it is unset
6051 since in normal SKE case, client to server connection, only
6052 the responder should do authentication. When doing SKE between
6053 two clients both should perform authentication. Updated the
6054 code and the protocol specs.
6056 * A little fix to IDENTIFY command in the server. Search the
6057 client first by hash not nickname. Affected file is
6060 * Fixed the silc_client_close_connection to support closing
6061 the client to client connections wihtout deleting too much
6062 data. Affected file lib/silcclient/client.c.
6064 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6065 are received if protocol used to be active but is not anymore
6066 the application would crash due to NULL pointer dereference.
6067 Affected files silcd/server.c and lib/silcclient/client.c.
6069 * Added `hash' field to the SilcClientConnection to include
6070 the hash function negotiated in the SKE protocol.
6072 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6073 to set the channel founder authentication data. A client can
6074 claim the founder rights later by providing the authentication
6075 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6076 This way the channel founder can regain the channel founder
6077 privileges even it is left the channel. This works only on
6078 local server and the client must be connected to the same
6079 server to be able to regain the founder rights. Updated the
6080 protocol specs accordingly.
6082 Added support to the CMODE command in the client to set the
6083 founder auth data. Read the README to see how to set it.
6085 Added support to the CUMODE command to claim the founder
6086 rights. Read the README to see how to do it.
6088 Added support for the founder authentication to the Channel
6089 Entry in the server. Affected file silcd/idlist.h.
6091 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6092 server's CMODE command. Affected file silcd/command.c.
6094 * Added the following new functions into lib/silccore/silcauth.[ch]:
6095 silc_auth_get_method and silc_auth_get_data.
6097 * The server now saves the remote hosts public key to the
6098 SilcIDListData pointer. Affected file silcd/protocol.c.
6100 * The normal server now does not remove the channel entry from
6101 the cache if the founder authentication data is set. It used
6102 to remove it if the founder was the last one on the channel on
6103 the server and left the channel. The auth data is saved and
6104 if the channel is re-joined later the old entry is used with
6105 the old auth data. Affected files silcd/command_reply.c and
6108 * Removed the `pkcs' field from the SilcIDListData structure
6109 in the server; it is not used. Affected file silcd/idlist.h.
6111 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Fixed packet processing on slow links. Partial packets were
6114 never re-processed because the incoming data buffer was cleared
6115 by the application. Application must not directly clear the
6116 sock->inbuf, the packet processing routines handle it. Fixed
6117 this in client library and in server.
6119 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Fixed the WHOIS and IDENTIFY send reply function to really
6122 check whether to send list or just one entry. Affected file
6125 * Cleaned up the LEAVE command's channel key distribution. The
6126 affected file silcd/command.c.
6128 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6129 can enforce the channel mode as well. In that case the ID
6130 includes the ID of the server. The code now enforces the
6131 mode change if the router have different mode than the server.
6133 * The notify client operation with CMODE_CHANGE notify can now
6134 return NULL client_entry pointer if the CMODE was not changed
6135 by client. Application must check for this.
6137 * Added <Server ID> argument to INFO command to support server
6138 info fetching by Server ID.
6140 * Added silc_server_announce_get_channel_users to get assembled
6141 packets of channel users of the specified channel. Affected
6142 file silcd/server.[ch].
6144 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6145 was freed underneath the ID Cache.
6147 * Re-announce clients when the server received CHANNEL_CHANGE
6148 notify from the router. Affected file silcd/packet_send.c.
6150 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6153 crashed since it did not handle the fact that there is no cipher
6154 called "3" and didn't check the error condition. Now fixed.
6156 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6157 flag. It can be used to send message requests.
6159 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Implemented the RESTART command in the client.
6163 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6164 notice type messages. Added notice printing to the user
6167 * The channel keys are not re-generated if the channel's mode
6168 is PRIVKEY, ie private key on the channel exists. Affected
6169 files silcd/server.c and silcd/command.c.
6171 * Fixed a little bug in channel message delivery when channel
6172 private keys are set in the server. Affected file is
6173 silcd/packet_send.c.
6175 * Changed the setting on channel->on_channel = TRUE from the
6176 silc_client_save_channel_key to the JOIN command reply. The
6177 key payload is not received if the private channel key is set.
6178 Affected file lib/silcclient/command_reply.c and the
6179 lib/silcclient/client_channel.c.
6181 * When the CMODE_CHANGE notify is sent and the channel private
6182 key mode is removed the channel key must be re-generated in
6183 other cells as well. Added this support for the router in the
6184 silcd/packet_receive.c.
6186 * Added new local command NOTICE to send notice message on
6187 channel. Affected file silc/local_command.[ch].
6189 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Added new local command ME to the client. It is used to send
6192 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6193 some action. Affected file silc/local_command.[ch].
6195 * Changed channel_message and private_message client operations
6196 to deliver the message flags to the application. Added also
6197 the `flags' arguments to the silc_client_send_channel_message
6198 and silc_client_send_private_message functions. Affected file
6201 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Redefined the Private Message Payload to support private message
6204 keys and to support the new private message flags. Updated
6205 the protocol specs. Flags makes it possible to have for example
6206 CTCP style messages.
6208 * Added new type SilcPrivateMessagePayload and defined an API
6209 for it in the lib/silcclient/silcprivate.[ch].
6211 * Tested private message private keys successfully. Tested the
6212 private message key set, unset and list commands with the new
6215 * Redefined the Channel Message Payload to include the channel
6216 message flags (equal with private message flags) to support
6217 for example CTCP style messages.
6219 * Defined some of the message (for channel and private message)
6220 flags. Updated the protocol specs and added the flags to the
6221 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6223 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Added SilcKeyAgreementStatus type to the key agreement routines
6226 to indicate the current status and error if one occured.
6227 The status types are defined in the lib/silcclient/silcapi.h.
6229 * Added new local command KEY that is used to set and unset private
6230 keys for channels, set and unset private keys for private messages
6231 with remote clients and to send key agreement requests and
6232 negotiate the key agreement protocol with remote client. The
6233 key agreement is supported only to negotiate private message keys,
6234 it currently cannot be used to negotiate private keys for channels,
6235 as it is not convenient for that purpose.
6237 * Fixed a minor pending callback setting bug in the function
6238 silc_client_get_client_by_id_resolve, now the function works.
6239 Affected file lib/silcclient/idlist.c.
6241 * Added function silc_net_get_local_port to get local bound
6242 port by socket. Added to lib/silcutil/silcnet.[ch].
6244 * Added `sockets' and `sockets_count' fields to the SilcClient
6245 object. They hold the sockets of the listenning sockets in
6246 the client. Listenning sockets may be for example the key
6247 agreement server. Affected file lib/silcclient/client.[ch].
6248 Added functions the silc_client_add_socket and the
6249 silc_client_del_socket. They are exported to the application
6252 * Added ~./silc/clientkeys to support other client's public keys.
6254 * Renamed verify_server_key client operation to verify_public_key
6255 and added one argument to indicate the type of the connection
6256 (server, client etc.).
6258 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added silc_server_connection_auth_request to handle the
6261 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6262 silcd/packet_receive.[ch].
6264 * Added silc_server_send_connection_auth_request into the
6265 silcd/packet_send.c to send the connection auth request packet.
6267 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6270 * Fixed the public key authentication in responder side in the
6271 server. The `auth_data' pointer includes the SilcPublicKey
6272 not the path to the public key. Affected file silcd/protocol.c.
6274 * Implemented the public key authentication in the initiator side
6275 in the server. Affected file silcd/protocol.c.
6277 * Removed the [RedirectClient] config section from the server
6278 configuration. Is not needed and I don't want to implement it.
6280 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Cleaned up the CMODE command in the server. It now works
6283 correctly and supports all the modes defined in the protocol.
6284 Affected file is silcd/command.c.
6286 * Added `hmac_name' field to the SilcChannelEntry in the server
6287 to hold the default HMAC of the channel. It can be set when
6288 creating the channel (with JOIN command). Affected files
6291 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6292 type to indicate the change of the current cipher and hmac
6293 on the channel. Client can safely ignore the <cipher> argument
6294 (if it chooses to do so) since the CHANNEL_KEY packet will
6295 force the channel key change anyway. The <hmac> argument is
6296 important since the client is responsible of setting the new
6297 HMAC and the hmac key into use.
6299 * Fixed the CMODE command in the client library as well.
6301 * Tested CMODE command in router environment successfully.
6303 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Show the version of the remote client (or server) when connecting
6306 to the server. It is logged to the log file. Affected file
6307 is silcd/protocol.c.
6309 * Fixed the KILLED notify handling in the client library. The
6310 client must be removed from all channels when receiving the
6313 Also, do not remove the client entry when giving the KILL
6314 command but when the KILLED notify is received.
6316 * Removed silc_idlist_find_client_by_nickname from the server.
6317 Not needed anymore. Affected files silcd/idlist.[ch].
6319 * Implemented the CHANNEL_CHANGE notify type handling to the
6320 server. Affected file silcd/server.c.
6324 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6338 * Added function silc_server_get_client_resolve to find the
6339 client entry by ID from all ID lists and then resolve it
6340 (using WHOIS) if it cannot be found. Affected file is
6343 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Implemented the BAN command to the client library.
6347 * The JOIN command in the server now checks the invite list
6350 * Changed the silc_command_reply_payload_encode_va and the
6351 silc_command_payload_encode_va to support that if argument is
6352 NULL it ignores and checks the next argument. Affected file
6353 lib/silccore/silccommand.c.
6355 * Added silc_server_send_notify_ban to send the BAN notify
6356 type between routers.
6358 * Chaned the silc_notify_payload_encode to support that if
6359 argument is NULL it ignores and checks the next argument.
6360 Affected file lib/silccore/silcnotify.c.
6362 * Tested ban lists in router environment successfully.
6364 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Implemented BAN command to the server, in silcd/command.[ch].
6368 * Removed the BAN and INVITE_LIST modes from the CMODE command
6371 * Added function silc_string_match to regex match two strings.
6372 Affected files lib/silcutil/silcutil.[ch].
6374 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Redefined parts of the SilcChannelEntry in the server to support
6377 the new ban and invite lists.
6379 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6381 * Redefined the INVITE command. The same command can be used to
6382 invite individuals to the channel but also to manage the invite
6383 list of the channel (to add to and remove from the invite list).
6384 Updated the protocol specs.
6386 * Added new command SILC_COMMAND_BAN that can be used to manage
6387 the ban list of the channel. Updated the protocol specs.
6389 * Removed the channel modes: the SILC_CMODE_BAN and the
6390 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6391 in the CMODE command. The equivalent features are now available
6392 using INVITE and BAN commands. Updated the protocol specs.
6394 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6395 in the network about change in the current ban list. The notify
6396 type is not used by the client.
6398 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6399 support the invite lists.
6401 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added new function silc_string_regexify that converts string
6404 including wildcard characters into regex string that can
6405 be used by the GNU regex library. Added into the file
6406 lib/silcutil/silcutil.[ch].
6408 Added silc_string_regex_combine to combine to regex strings
6409 into one so that they can be used as one regex string by
6410 the GNU regex library. Added into the file
6411 lib/silcutil/silcutil.[ch].
6413 Added silc_string_regex_match to match two strings. It returns
6414 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6416 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Imported GNU regex to the soruce tree into lib/contrib.
6419 Fixed some compiler warning from the regex.c.
6421 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Fixed MOTD command in the server to work in router environment.
6425 * Fixed the MOTD command in the client library to support
6426 the server argument in the command.
6428 * Added `nickname_len' argument to the silc_idlist_add_client
6429 in the server, as the `nickname' argument may be binary data
6432 * Added silc_idlist_get_channels to return all channels from
6435 * Implemented LIST command to the server. Affected file is
6438 * Implemented the LIST command to the client library and on the
6441 * Added [<user count>] argument to the LIST command reply.
6442 With private channels the user count is not shown.
6444 * Updated TODO and README.
6446 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * The client entry's data.registered must be TRUE even with
6449 global client entry on global client list. The data.registered
6450 is used to check whether the client is anymore in the network,
6451 for example with WHOWAS command so it must be valid.
6453 * Fixed the WHOWAS command in the server. It now actually works
6454 in router environment. Added function into silcd/command_reply.c
6455 silc_server_command_reply_whowas_save.
6457 * Added silc_idlist_purge function to the silcd/idlist.c
6458 to periodically purge the ID Cache.
6460 * Fixed INFO command in the server. It works now in router
6461 environment. Added <server name> argument to the INFO command
6462 reply. Updated the protocol specs.
6464 * Fixed minor bug in silc_idcache_purge to not purge if the
6465 expire value is zero.
6467 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6468 they were buggy because of the WHOWAS information.
6470 * Fixed local command MSG to handle the async resolving of
6471 the remote client properly. It used to fail the first MSG.
6472 Affected file silc/local_command.c.
6474 * Added `data_len' field to SilcIDCache context.
6476 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Update TODO. Todo in commands in the server.
6480 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6483 used by routers as broadcast packet to inform other routers
6484 about the changed user mode.
6486 Implemented the notify handling in the server. Affected file is
6487 silcd/packet_receive.c. Added the function
6488 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6490 * Added new generic Channel Payload and deprecated the New Channel
6491 Payload. The New Channel Payload is now the generic Channel
6494 * Added new argument `mode' to the silc_server_send_new_channel
6495 as it is required in the Channel Payload now.
6497 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6498 and created a new and real SilChannelPayload to represent the
6499 new generic Channel Payload. Implemented the encode/decode
6500 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6502 * Added silc_server_get_client_channel_list to return the list
6503 of channels the client has joined for WHOIS command reply.
6504 Affected file silcd/server.[ch].
6506 * Implemented the channel list sending in the WHOIS command reply
6507 in server and in the client.
6509 Implemented the channel list displaying on the user interface
6510 as well. Affected file silc/client_ops.c.
6512 * Added silc_channel_payload_parse_list to parse list of Channel
6513 Payloads. It returns SilcDList list of SilcChannelPayloads.
6514 Client for example can use this function to parse the list of
6515 channels it receives in the WHOIS command reply. The caller
6516 must free the list by calling silc_channel_payload_list_free.
6517 Affected files lib/silccore/silcchannel.[ch].
6519 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Added one new argument <user mode> to the WHOIS command reply
6522 to return the mode of the user in SILC. Updated the protocol
6525 Implemented it to the server and client.
6527 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Fixed the mode printing on the user interface on joining.
6530 Affected file silc/client_ops.c.
6532 * Implemented the UMODE command and user modes in general to the
6533 client library and to the user interface.
6535 * Implemented the UMODE command to the server.
6537 * The server now sends UNKNOWN_COMMAND error status if client sends
6538 unknown command. Affected file silcd/command.c.
6540 * All server commands now handle the command identifier the right
6541 way when sending the command reply to the client. The client can
6542 use to identify the command replies with the identifier.
6544 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Added silc_server_get_client_route to resolve the route to
6547 the client indicated by the client ID. Affected file is
6550 * Added silc_server_relay_packet as general function to relay
6551 packet to arbitrary destination. This deprecates functions
6552 like _send_private_message_key, _relay_notify etc. Affected
6553 file is silcd/packet_send.[ch].
6555 Removed silc_server_send_key_agreement,
6556 silc_server_send_private_message_key and
6557 silc_server_packet_relay_notify functions from the file
6558 silcd/packet_send.[ch].
6562 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6563 server. Affected file silcd/packet_receive.[ch].
6565 * Implemented the KILL command to the client. Implemented the
6566 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6567 Affected files lib/silcclient/command[_reply].c and
6568 lib/silcclient/client_notify.c. Implemented the KILL notify
6569 printing in the user inteface.
6571 * Fixed a lot silc_parse_nick memory leaks from the client
6572 library in the file lib/silcclient/command.c.
6574 * Changed the silc_server_send_notify_on_channels's `sender'
6575 argument from SilcSocketConnection to SilcClientEntry to
6576 check the sender as entry and not as connection object and not
6577 to send to the client provided as argument. The affected file
6578 is silcd/packet_send.[ch].
6580 * The notify packets that are destined directly to the client used
6581 to not to be processed by the server. Now changed that and the
6582 server processes all notify packets. After relaying the packet
6583 to the client the notify packet is processed in the server.
6585 * The silc_server_free_client_data now checks whether there is
6586 pending outgoing traffic for the client and purges the data to
6587 the network before removing the client entry.
6589 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6592 an client is killed from the SILC Network. Updated the protocol
6595 Added new function silc_server_send_notify_killed to the
6596 silcd/packet_send.[ch].
6598 * Added function silc_server_packet_relay_notify to relay notify
6599 packets that are destined directly to a client. In this case
6600 the server does not process the notify packets but merely relays
6601 it to the client. Affected file silcd/packet_send.[ch].
6603 Added also silc_server_packet_process_relay_notify to check
6604 whereto relay the notify. Affected file is
6605 silcd/packet_receive.[ch].
6607 * Implemented the KILL command to the server.
6611 * Added the backup schema desgined last fall to the protocol
6612 specs for everyone to see. The specification is in the
6613 *-spec-xx.txt draft and the packet type definitions for the
6614 backup routers is in *-pp-xx.txt draft. Thusly, added also
6615 new packet type SILC_PACKET_CELL_ROUTERS.
6617 * A big security problem in the implementation discovered. The
6618 signoff of an client did not cause new channel key generation
6619 which it of course should've done. The channel keys must be
6620 always re-generated when client leaves (or signoffs) the channel.
6621 The silc_server_remove_from_channels funtion now handles
6622 the channel key re-generation.
6624 * Added `sender' argument to the silc_server_send_notify_on_channels
6625 to not to send the client provided as argument. Affected file
6626 silcd/packet_send.[ch].
6628 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Implemented OPER and SILCOPER commands into the server and
6633 * Added silc_auth_verify and silc_auth_verify_data to verify
6634 the authentication directly from the authentication payload.
6635 It supports verifying both passphrase and public key based
6636 authentication. Affected file lib/silccore/silcauth.[ch].
6638 * Added `hash' field to the SilcIDListData structure. It is the
6639 hash negotiated in the SKE protocol. Affected file is
6642 * Slight redesigning of the SilcAuthPayload handling routines.
6643 Do not send SilcPKCS but SilcPublicKey as argument.
6645 * Implemented the public key authentication support to the
6646 serverconfig. The public key is loaded from the provided path
6647 and saved as authentication data to void * pointer. Thus,
6648 changed the unsigned char *auth_data to void *auth_data;
6650 * Fixed SHUTDOWN command to send the reply before the server
6651 is shutdown. :) Affected file silcd/command.c.
6653 * Fixed fatal bug in CONNECT command. The hostname was invalid
6654 memory and server crashed. Affected file silcd/command.c.
6656 * Fixed fatal bug in CLOSE command. The server_entry became
6657 invalid but was referenced later in the command. Affected file
6660 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Fixed fatal bug in failure packet handling. Server ignored
6663 the failure and thus crashed when it came.
6667 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6670 that the command may be executed only once in (about) 2 seconds.
6671 The old SILC_CF_LAG flag is same but allows command bursts up
6672 to five before limiting.
6674 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6675 server code. Various commands now includes the CF_LAG_STRICT
6676 flag to disallow any kind of miss-use of the command.
6678 * Fixed the silc_buffer_unformat to not to allocate any data
6679 if the length of the data is zero. It used to allocate the
6680 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6682 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Changed the format of AdminConnection configuration section
6685 in the server. Added username of the admin to the format.
6686 Affected files silcd/serverconfig.[ch].
6688 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6689 to return admin configuration data by host, username and/or
6692 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Implemented WHOWAS command to the server. Added the functions:
6696 silc_server_command_whowas_parse,
6697 silc_server_command_whowas_send_reply,
6698 silc_server_command_whowas_from_client and
6699 silc_server_command_whowas_from_server
6701 * Added <Client ID> argument to the WHOWAS command reply. Updated
6702 the protocol specs accordingly.
6704 * Implemented WHOWAS command and command_reply to the client
6707 Implemented the WHOWAS printing on the user interface.
6709 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Added new argument to the WHOWAS command reply, the real name.
6712 It is an optional argument. Updated the protocol specs.
6714 * Added SilcIDCacheDestructor callback that is registered when
6715 the SilcIDCache is allocated. The callback is called when
6716 an cache entry in the ID Cache expires, or is purged from the
6717 cache. Added into lib/silccore/idcache.[ch].
6719 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6720 to destruct the client entries when the cache entry expires.
6721 Other ID Cache's in server and in the client library ignores
6724 * If the ID Cache entry's `expire' field is zero then the entry
6725 never expires. Added boolean `expire' argument to the
6726 silc_idcache_add function in the lib/silccore/idcache.[ch].
6727 If it is TRUE the default expiry value is used.
6729 * Added silc_server_free_client_data_timeout that is registered
6730 when client disconnects. By default for 5 minutes we preserve
6731 the client entry for history - for WHOWAS command.
6733 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added support to the server to enforce that commands are not
6736 executed more than once in 2 seconds. If server receives
6737 commands from client more frequently, timeout is registered
6738 to process the commands. Affected file silcd/command.c.
6739 Added new function silc_server_command_process_timeout.
6741 * Changed NICK_NOTIFY handling in client library to check that
6742 if the client's nickname was changed, so there is no need to
6743 resolve anything from the server.
6745 * Removed error printing from the WHOIS and IDENTIFY commands.
6746 If error occurs then it is ignored silently in the client library.
6747 The application, however, may map the received error to
6748 human readable error string. The application currently maps
6749 the NO_SUCH_NICKNAME error to string.
6751 * Made the command status message public to the application. Moved
6752 them from lib/silcclient/command_reply.c to
6753 lib/silcclient/command_reply.h. The application can map the
6754 received command status to the string with the
6755 silc_client_command_status_message function.
6757 * Added check to the server to check that client's ID is same
6758 as the Source ID in the packet the client sent. They must
6761 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Added dist-bzip hook to the Makefile.am to make bzip2
6764 compressed distributions.
6766 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Server now enforces the maximum length for the nickname and
6769 the channel as protocol specification dictates. 128 bytes for
6770 nickname and 256 bytes for channel name.
6772 * Moved the WHOIS printing to the application. The client libary
6773 does not print out the WHOIS information anymore, the application
6774 must do it. Renamed silc_client_command_reply_whois_print to
6775 the silc_client_command_reply_whois_save.
6777 The client's idle time is also sent to the application now, and
6778 the idle is shown on screen.
6780 * Added silc_client_command_reply_identify_save to save the
6781 received IDENTIFY entries.
6783 * Do not check for channel private keys in message sending and
6784 reception if the channel does not have the PRIVKEY mode set.
6785 Affected file lib/silclient/client_channel.c.
6787 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6790 just surfaced after chaning the JOIN procedure.
6792 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Added silc_client_get_clients_by_list to get client entries
6795 from Client ID list, that is returned for example by JOIN
6796 and USERS command replies. The application should use this
6797 function for example when JOIN command reply is received to
6798 resolve the clients already on the channel (library does not
6799 do that anymore as USERS command reply is not used in the JOIN
6800 procedure anymore). Affected files lib/silcclient/silcapi.h and
6801 lib/silcclient/idlist.c.
6803 * JOIN command reply and USERS command reply returns now SilcBuffer
6804 pointers instead of unsigned char pointers when returning
6805 the client list and mode list.
6807 * Added <Client ID> argument to the JOIN command reply, mainly
6808 for the server to identify for which client the command was
6809 originally sent. Updated protocol specs accordingly.
6811 * Added SilcDlist private_key pointer to the SilcChannelEntry
6812 in the client to support the channel private keys. Affected
6813 file is lib/silcclient/idlist.h.
6815 * Added SilcChannelPrivateKey argument to the function
6816 silc_client_send_channel_message so that application can choose
6817 to use specific private ke if it wants to. If it is not provided,
6818 the normal channel key is used, unless private keys are set.
6819 In this case the first (key that was added first) is used
6820 as the encryption key.
6822 * Implemented the support for channel private key handling.
6823 Implemented the following functions:
6825 silc_client_add_channel_private_key,
6826 silc_client_del_channel_private_keys,
6827 silc_client_del_channel_private_key,
6828 silc_client_list_channel_private_keys and
6829 silc_client_free_channel_private_keys
6831 Affected file lib/silcclient/client_channel.c.
6833 * Added the support for the private keys in the channel message
6834 sending and encryption and in the message reception and
6835 decryption. Affected funtions are
6836 silc_client_send_channel_message and silc_client_channel_message.
6838 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Added SKE's key verify callback to the client library's
6841 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6843 * Removed the statement that server (or router) must send USERS
6844 command reply when joining to the channel so that the client
6845 knows who are on the channel. Instead, the client list and
6846 client's mode list is now sent in the JOIN command reply to the
6847 client who joined channel. This is better solution.
6849 * Added function silc_server_get_users_on_channel and function
6850 silc_server_save_users_on_channel to the silcd/server.[ch].
6852 * Removed function silc_server_command_send_users from the
6855 * Do not show topic on the client library anymore. The topic is
6856 sent in the command reply notify to the application and the
6857 application must show the topic now.
6859 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Added client searching by nickname hash into the IDENTIFY and
6862 WHOIS commands in the server as they were clearly missing from
6863 them. Affected file is silcd/command.c.
6865 * Fixed a bug in private message receiving in the client library.
6866 The remote ID was freed and it wasn't supposed, now it is
6869 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Minor fix to the channel payload; allocate the data area, as it
6872 needs to be of specific length.
6874 * If the key agreement port is zero then the operating
6875 system will define the bound port. Affected files are
6876 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6878 * Added new function silc_channel_payload_decrypt into the file
6879 lib/silccore/silcchannel.[ch].
6881 * Moved the channel message etc, check from silc_packet_decrypt
6882 to applications. The library calls now a generic
6883 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6884 when the packet is either normal or special. This was done to
6885 allow more wide range of checking that was not allowed when
6886 the code was in library. Now applications can do virtually any
6887 checks to the packet and return to the library the decision how
6888 the packet should be processed. Affected files are
6889 lib/silccore/silcpacket.[ch].
6891 Added silc_server_packet_decrypt_check to the server and
6892 silc_client_packet_decrypt_check to the client library.
6894 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6895 to send with specified source and destination information.
6897 * Channel message delivery between routers was broken after the
6898 channel key distribution was fixed earlier. The channel key
6899 was used be to distributed to other routers as well which is not
6900 allowed by the protocol. Now this is fixed and channel keys
6901 really are cell specific and the channel message delivery between
6902 routers comply with the protocol specification.
6904 * Fixed various commands in server to check also the global list
6905 for the channel entry and not just the local list. The affected
6906 file silcd/command.c.
6908 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added assert()s to buffer formatting and unformatting routines
6911 to assert (if --enable-debug) when error occurs. Affected
6912 file: lib/silcutil/silcbuffmt.c.
6914 * Changed to auto-reconnect to check whether the remote host is
6915 router and register the re-connect timeout if it is. It used
6916 to check that whether we are normal server, but router must do
6917 auto-reconnect with another router as well. Affected file
6920 * Removed the [<key len>] option from CMODE command as the cipher
6921 name decides the key length, nowadays. See the defined ciphers
6922 from the protocol specification.
6924 * Added [<hmac>] option to the CMODE command to define the HMAC
6925 for the channel. Added SILC_CMODE_HMAC channel mode.
6927 * Added [<hmac>] option for the JOIN command so that user can
6928 select which HMAC is used to compute the MACs of the channel
6931 * Added Hmac field to the Channel Message Payload. The integrity
6932 of plaintext channel messages are now protected by computing
6933 MAC of the message and attaching the MAC to the payload. The
6934 MAC is encrypted. Now, it is clear that this causes some
6935 overhead to the size of the packet but rationale for this is that
6936 now the receiver can verify whether the channel message decrypted
6937 correctly and also when private keys are set for the channel the
6938 receiver can decrypt the packet with several keys and check from
6939 the MAC which key decrypted the message correctly.
6941 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6942 lib/silccrypt/silccipher.[ch].
6944 * Added silc_hash_len to return the digest length into the
6945 lib/silcrypt/silchash.[ch].
6947 * Rewrote parts of Silc Channel Payload interface in the
6948 lib/silccore/silcchannel.[ch]. The encode function now also
6949 encrypts the packet and parse function decrypts it.
6951 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6953 * Fixed a minor formatting bug in the SKE's key material processing.
6954 It actually might have processed the keys wrong way resulting
6957 * Redefined the mandatory HMAC algorithms and added new algorithms.
6958 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6959 and hmac-md5 truncated to 96 bits. The mandatory is now
6960 hmac-sha1-96. Rest are optional (including the one that used
6961 to be mandatory). Rationale for this is that the truncated HMAC
6962 length is sufficient from security point of view and can actually
6963 make the attack against the HMAC harder. Also, the truncated
6964 HMAC causes less overhead to the packets. See the RFC2104 for
6967 * Added new [hmac] configuration section. The SKE used to use
6968 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6969 is of course wrong. The official names that must be proposed in
6970 the SKE are the ones defined in the protocol specification
6971 (hmac-sha1-96 for example). The user can configure any hmac
6972 using any hash function configured in the [hash] section. At
6973 least, the mandatory must be configured.
6975 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6977 * Added HMAC list to the SKE proposal list. It has now both
6978 hash algorithm list and HMAC list. This makes the protocol
6979 incompatible with previous versions. The SKE now seems to work
6980 the way it is supposed to work, for the first time actually.
6982 * Defined plain Hash algorithms to the protocol specification.
6985 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Implemented support for key agreement packets into the server.
6988 Added functions silc_server_key_agreement and
6989 silc_server_send_key_agreement. Other than these functions,
6990 server has nothing to do with this packet.
6992 * Added support for private message key packets into the server.
6993 Added functions silc_server_private_message_key and
6994 silc_server_send_private_message_key.
6998 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6999 called in the protocol's final callback instead in the END
7000 protocol state. This makes a little more sense and in the same
7001 time in client we can use the same protocol routines for normal
7002 key exchange and to key agreement packet handling as well.
7004 * Added to both client's and server's KE protocol context the
7005 SilcSKEKeyMaterial pointer to save the key material. We will
7006 bring the key material to the protocol's final callback by doing
7007 this. The final callback must free the key material.
7009 * Added SKE's packet_send callback into client's KE protocol
7010 context so that the caller can choose what packet sending function
7011 is used. This way we can use different packet sending when
7012 doing normal SKE when doing key agreement packet handling (in
7013 the key agreement packet handling we do not want to encrypt
7016 * Implemented the responder side of the key agreement routines
7017 in the client. The client can now bind to specified port and
7018 accept incoming key negotiation. The key material is passed
7019 to the application after the protocol is over.
7021 * Implemented the processing of incoming Key Agreement packet
7022 in the client. Added function silc_client_key_agreement to
7025 * Implemented the intiator side of the key agreement routines
7026 in the client. The client can now initiate key agreement with
7027 another remote client. The key material is passed to the
7028 application after the protocol is over.
7030 * Created client_keyagr.c to include all the key agreement
7033 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7034 SILC_TASK_CALLBACK except that it is not static.
7036 * Created client_notify.c and moved the Notify packet handling
7037 from the client.[ch] into that file.
7039 * Created client_prvmsg.c and moved all private message and
7040 private message key routines from the client.[ch] into that file.
7042 * Create client_channel.c and moved all channel message and
7043 channel private key routines from the client.[ch] into that file.
7045 * Changed silc_client_get_client_by_id_resolve to resolve with
7046 WHOIS command instead of IDENTIFY command, in the file
7047 lib/silclient/idlist.c.
7049 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Implemented the SKE's responder side to the Client library.
7053 * When FAILURE is received to the protocol do not trust it
7054 blindly. Register a timeout to wait whether the remote closes
7055 the connection as it should do it, only after that process the
7056 actual failure. This was changed to both client and server.
7058 * Added client_internal.h to include some of the structures
7059 there instead of client.h in lib/silcclient/.
7061 * Added function silc_task_unregister_by_callback to unregister
7062 timeouts by the callback function.
7064 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Some "Incomplete WHOIS info" errors has been appearing on the
7067 log files. Took away the entry->userinfo check from WHOIS
7068 reply sending. The entry->userinfo is now " " if client did not
7069 provide one. I thought this was fixed earlier but something
7070 is wrong still. Let's see if the error still appears.
7072 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Fixed a minor bug in the login when the channel key is
7075 re-generated in the server. It used to generate the key in
7076 wrong order and thus caused problems in the channel traffic.
7078 * Fixed a minor bug in channel key distsribution after
7079 KICK command. The key was not sent to the router even though
7082 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Added silc_ske_process_key_material_data as generic routine
7085 to process any key material as the SILC protocol dictates. The
7086 function is used by the actual SKE library but can be used by
7087 applications as well. This relates to the private message keys
7088 and the channel private keys since they must be processed the
7089 same way the normal SILC session keys. The protocol dictates
7090 this. Affected files: lib/silcske/silcske.[ch].
7092 Added also silc_ske_free_key_material to free the
7093 SilcSKEKeyMaterial structure.
7095 * Defined silc_cipher_set_key function to set the key for
7096 cipher without using the object's method function. The affected
7097 files: lib/silccrypt/silccipher.[ch].
7099 * Implemented silc silc_client_add_private_message_key,
7100 silc_client_add_private_message_key_ske,
7101 silc_client_del_private_message_key,
7102 silc_client_list_private_message_keys and
7103 silc_client_free_private_message_keys functions in the
7106 Added functions silc_client_send_private_message_key to send
7107 the Private Message Key payload and silc_client_private_message_key
7108 to handle incoming Private Message Key payload.
7110 * Added Cipher field to the Private Message Key payload to set
7111 the cipher to be used. If ignored, the default cipher defined
7112 in the SILC protocol (aes-256-cbc) is used.
7114 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Removed lib/silcclient/ops.h file.
7118 Redefined parts of the SILC Client Library API. Created new
7119 file silcapi.h that deprecates the ops.h file and defines the
7120 published Client Library API. Defined also private message key
7121 API and channel private key API into the file.
7123 This is the file that the application must include from the
7124 SILC Client Library. Other files need not be included by
7125 the application anymore.
7127 * Added new key_agreement client operation callback and also
7128 defined the Key Agreement library API for the application.
7130 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7133 is used by clients to request key negotiation between another
7134 client in the SILC network. If the negotiation is started it
7135 is performed using the SKE protocol. The result of the
7136 negotiation, the secret key material, can be used for example
7137 as private message key.
7139 Implemented the Key Agreement payload into the files
7140 lib/silccore/silauth.[ch].
7142 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Redefined ciphers for the SILC protocol. Added some new ciphers
7145 and defined the key lengths for the algorithms. Changed the
7146 code accordingly. The default key length is now 256 bits.
7148 * Fixed SKE key distribution function silc_ske_process_key_material
7149 when the key length is more than 128 bits. The default key
7150 length in SILC is now 256 bits.
7152 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7153 to indicate unsupported algorithm.
7155 * Renamed rijndael.c to aes.c and all functions as well.
7157 * Fixed a long standing channel key setting bug in client library.
7158 Weird that it has never surfaced before.
7160 * Fixed bug in channel deletion. If the entire channel is removed
7161 then it must also delete the references of the channel entry
7162 from the client's channel list as the client's channel entry and
7163 the channel's client entry share same memory.
7165 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Implemented CONNECT and SHUTDOWN commands in the client.
7169 * Implemented CLOSE command to the client.
7171 * Added the function silc_idlist_find_server_by_name into the
7172 files silcd/idlist.[ch].
7174 Added the function silc_idlist_find_server_by_conn into the
7175 files silcd/idlist.[ch].
7177 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * DIE command was renamed to SHUTDOWN. Updated the both code
7182 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7183 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7185 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7188 * Added function silc_server_create_connection function to create
7189 connection to remote router. My server implementation actually
7190 does not allow router to connect to normal server (it expects
7191 that normal server always initiates the connection to the router)
7192 so the CONNECT command is only good for connecting to another
7195 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7198 or some other client was kicked from the channel.
7200 Implemented the handling of the notify type to both client
7203 Implemented silc_server_send_notify_kicked to send the KICKED
7204 notify. It is used to send it to the server's primary router.
7206 * Implemented the KICK command into server and client.
7208 * Added `query' argument to the silc_idlist_get_client function
7209 to indicate whether to query the client from server or not if
7212 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7213 to indicate that the client is not channel founder.
7217 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7219 * Removed the rng context from SilcPacketContext structure and
7220 changed that the packet routine uses the Global RNG API.
7222 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7224 * Added support for quit message that client can "leave" on the
7225 channel when it quits the SILC. It is ditributed inside the
7226 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7228 Added silc_server_free_client_data that will take the
7229 signoff message as argument.
7231 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7233 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Updated parts of the protocol specification to keep it up
7238 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7241 payloads in one packet.
7243 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7244 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7245 use now the new List flag.
7247 * Also deprecated the following packet types: REPLACE_ID,
7248 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7250 * Added list support for Notify packet in server.
7252 * Added silc_server_send_notify_channel_change to send the
7253 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7254 the silc_server_send_replace_id.
7256 * Added silc_server_send_notify_nick_change to send the
7257 NICK_CHANGE notify type. Deprecates the function
7258 silc_server_send_replace_id.
7260 * Added silc_server_send_notify_join to send the JOIN notify type.
7261 Deprecates the function silc_server_send_new_channel_user.
7263 * Added silc_server_send_notify_leave to send LEAVE notify type.
7264 Deprecates the function silc_server_send_remove_channel_user.
7266 * Added silc_server_send_notify_cmode and
7267 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7268 types. Deprecates the silc_server_send_set_mode function.
7270 * Added SERVER_SIGNOFF notify type to indicate that server has
7271 quit. This means that all clients on the channel from that
7272 server will drop. This can be also used when netsplit happens.
7274 Deprecated REMOVE_ID packet type since it is not needed anymore
7277 Added silc_server_send_notify_server_signoff to send the
7278 SERVER_SIGNOFF notify type. Deprecates the function
7279 silc_server_send_remove_id.
7281 Added also silc_server_send_notify_signoff to send the
7282 SIGNOFF notify type.
7284 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7285 SILC protocol from this day on. Changed the protocol
7286 specification as well.
7288 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7289 notify type. It is used between routers to notify about
7290 topic changes on a channel.
7292 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7295 * Partly updated the protocol specification to comply with the
7296 changes now made. It is still though a bit outdated.
7298 * The JOIN notify type now takes one extra argument <Channel ID>.
7299 The packet used to be destined to the channel but now the
7300 JOIN type may be sent as list thus it is impossible to
7301 destine it to any specific channel. By adding this argument
7302 it is again possible.
7304 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Added CREDITS file. The CHANGES and CREDITS file will appear
7307 in the distribution as well.
7309 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7312 types in the server's silcd/packet_receive.c.
7314 * Implemented CMODE and CUMODE to work in router environment.
7316 * Fixed minor encoding and decoding buglet from the
7317 lib/silccore/silcmode.c.
7319 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7322 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7324 * Changed all SilcConfigServer* and silc_config_server* to
7325 SilcServerConfig* and silc_server_config*, respectively.
7328 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Associated the ID (client or server ID) to the Authentication
7331 Payload to avoid any possibility of forging. Updated the
7332 protocol specification and the code accordingly.
7334 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * The RSA key length is now save to the RsaKey context in the
7337 key generation process in lib/silccrypt/rsa.c. The key length
7338 is now used to figure out the maximum size of the block allowed
7339 to be encrypted/signed.
7341 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7342 is equivalent to the silc_mp_mp2bin but does not allocate any
7345 * Changed silc_mp_mp2bin API to take length argument. If it is
7346 non-zero then the buffer is allocated that large. If zero, then
7347 the size is approximated using silc_mp_sizeinbase, which however
7350 * Created Global RNG API which is global RNG that application can
7351 initialize. After initializing, any routine anywhere in the
7352 code (including library) can use RNG without allocating a new
7353 RNG object. This was done to allow this sort of use of the
7354 RNG in code that has no chance to allocate RNG object. All
7355 applications currently allocate this and many routines in the
7356 library use this. Affected file lib/silccrypt/silcrng.[ch].
7358 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7359 it to use the Global RNG API.
7361 * Defined Authentication Payload into protocol specification that
7362 is used during SILC session to authenticate entities. It is
7363 used for example by client to authenticate itself to the server
7364 to obtain server operator privileges.
7366 Implemented this payload into the lib/silccore/silcauth.[ch].
7367 Implemented also routines for public key based authentication
7368 as the new protocol specification dictates.
7370 Moved definitions of different authentication methods from
7371 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7373 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7374 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7375 silc_pkcs_verify_with_hash functions into the file
7376 lib/silccrypt/silcpkcs.[ch].
7378 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * The client entry's userinfo pointer must be always valid.
7381 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7382 will fail since it requires the userinfo. Now, the userinfo
7383 is allocated as "" if actual userinfo does not exist. Actually,
7384 it must exist and it is totally Ok to drop client connections
7385 that does not announce the userinfo. However, we will make
7386 this workaround for now.
7388 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7389 to return the remote port by socket.
7391 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7393 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7394 SILC_SERVER_PENDING_EXEC and added an new macro
7395 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7396 data or when error occurs while processing the pending command.
7398 Added new argument `destructor' into silc_server_command_pending
7399 and to the SilcServerCommandPending object. This destructor is
7400 now called after calling the pending callback or if error occurs
7401 immediately. If error occurs the actual pending callback won't
7402 be called at all - only the destructor. The destructor may be
7403 NULL if destructor is not needed.
7405 All this applies for client library code as well. Similar
7406 changes were made there as well for the pending commands.
7408 In the client, the application must now allocate the
7409 SilcClientCommandContext with the silc_client_command_alloc
7412 * Added reference counter to the SilcServerCommandContext. Added
7413 function silc_server_command_alloc and silc_server_command_dup
7416 Same type of functions added to the client library for the same
7419 * Removed the cmd_ident from IDListData away since it is now
7420 global for all connections. It is the command identifier used
7421 in command sending and with pending commands. The affected file
7424 * Added reference counter to the SilcSocketConnection objecet to
7425 indicate the usage count of the object. The object won't be
7426 freed untill the reference counter hits zero. Currently only
7427 server uses this, and client ignores it. The client must be
7428 set to use this too later. The affected files are
7429 lib/silccore/silcsockconn.[ch]. Added also the function
7430 silc_socket_dup to increase the reference counter.
7432 This was mainly added because it is possible that the socket
7433 is removed underneath of pending command or other async
7434 operation. Now it won't be free'd and proper DISCONNECTING
7435 flags, etc. can be set to avoid sending data to connection that
7436 is not valid anymore.
7438 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7439 the connection. After that it sets SILC_SET_DISCONNECTED.
7440 It is, however, possible that the socket data is not still freed.
7441 The silc_server_packet_process now checks that data is not
7442 read or written to connection that is DISCONNECTED. The socket
7443 get's freed when the reference counter hits zero.
7445 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Changed the client operation API: channel_message operation's
7448 `sender' is now the client entry of the sender, not the nickname
7449 and the `channel' is the channel entry, not the channel name.
7451 In the private_message operation the `sender' is now also the
7452 client entry of the sender not the nickname.
7454 Affected file is lib/silcclient/ops.h and all applications
7455 using the client operations.
7457 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7459 * Moved the calling of ops->connect() from connect_to_server_final
7460 into receive_new_id functin since that is the point when the
7461 client is actually allowed to send traffic to network. The
7462 affected file is lib/silcclient/client.c.
7464 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7467 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7468 (if needs broadcasting) instead of broadcasting the packets one
7469 by one which would make a burst in the network traffic.
7471 * Added `broadcast' argument to the functions in silcd/server.[ch]
7472 silc_server_create_new_channel[_with_id] to indicate whether
7473 to send New Channel packet to primary router.
7475 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Added new function into the silcd/server.[ch] files:
7478 silc_server_create_new_channel_with_id to create new channel with
7479 already existing Channel ID.
7481 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7482 lib/silccore/silcpacket.h. This packet is used t send list of
7483 Set Mode payloads inside one packet. Server uses this to set
7484 the modes for the channels and clients on those channels, that it
7485 announced to the router when it connected to it. The protocol
7486 specification has been updated accordingly.
7488 * The silc_server_new_channel did not handle the packet coming
7489 from normal server as it normally does not send that. However,
7490 when it announces its channels it does send it. Implemented
7491 the support for that.
7493 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7494 into the file lib/silccore/id.h.
7496 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Fixed memory leaks in the functions silc_idlist_del_client,
7499 silc_idlist_del_channel and silc_idlist_del_server in the file
7500 silcd/idlist.c. All of those leaked like a sieve.
7502 * Fixed some small memory leaks in the client's function
7503 silc_client_notify_by_server.
7505 * Added functions into silcd/server.c: silc_server_announce_clients,
7506 silc_server_announce_channels and silc_server_announce_server.
7507 These functions are used by normal and router server to announce
7508 to its primary router about clients, channels and servers (when
7509 router) that we own. This is done after we've connected to the
7512 These functions effectively implements the following packet types:
7513 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7514 and SILC_PACKET_NEW_ID_LIST.
7516 * Added new functions into the silcd/packet_receive.[ch]:
7517 silc_server_new_id_list, silc_server_new_channel_list and
7518 silc_server_new_channel_user_list to handle the incoming
7519 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7521 * Added support of changing Channel ID in the function
7522 silc_server_replace_id. If the server that announces a channel
7523 to the router already exists in the router (with same name but
7524 with different Channel ID), router is responsible to send
7525 Replace ID packet to the server and force the server to change
7526 the Channel ID to the one router has.
7528 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7529 client that the Channel ID has been changed by the router. The
7530 normal server sends this to the client. Client must start using
7531 the new Channel ID as the channel's ID.
7533 Implemented handling of this new type into lib/silcclient/client.c
7534 into the function silc_client_notify_by_server.
7536 * Added new function silc_idlist_replace_channel_id into the files
7537 silcd/idlist.[ch] to replace the Channel ID.
7539 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Call silc_server_command_identify_check always when processing
7542 the IDENTIFY command in silcd/command.c
7544 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7546 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7547 send keepalive packets. The packet can be sent by clients,
7548 servers and routers.
7550 Added function silc_socket_set_heartbeat into the file
7551 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7552 If not set, the heartbeat is not performed. The actual
7553 heartbeat is implemented in the low level socket connection
7554 library. However, application is responsible of actually
7557 Added silc_server_send_heartbeat to send the actual heartbeat
7558 packet into silcd/packet_send.[ch]. Server now performs
7559 keepalive with all connections.
7561 * Added silc_task_get_first function into lib/silcutil/silctask.c
7562 to return the timeout task with shortest timeout. There was a bug
7563 in task unregistration that caused problems. TODO has been
7564 updated to include that task system must be rewritten.
7566 * The client library will now resolve the client information when
7567 receiving JOIN notify from server for client that we know but
7568 have incomplete information.
7570 * Rewrote parts of silc_server_remove_from_channels and
7571 silc_server_remove_from_one_channel as they did not remove the
7572 channel in some circumstances even though they should've.
7574 * Encryption problem encountered in server:
7576 The LEAVE command used to send the Channel Key packet to the
7577 router immediately after generating it. However, the code
7578 had earlier sent Remove Channel user packet but not immediately,
7579 ie. it was put to queue. The order of packets in the router
7580 was that Channel Key packet was first and Remove Channel User
7581 packet was second, even though they were encrypted in the
7582 reverse order. For this reason, MAC check failed. Now, this
7583 is fixed by not sending the Channel Key packet immediately but
7584 putting it to queue. However, this is more fundamental problem:
7585 packets that are in queue should actually not be encrypted
7586 because packets that are sent immediately gets encrypted
7587 actually with wrong IV (and thus MAC check fails). So, packets
7588 that are in queue should be encrypted when they are sent to
7589 the wire and not when they put to the queue.
7591 However, the problem is that the current system has not been
7592 designed to work that way. Instead, the packet is encrypted
7593 as soon as possible and left to the queue. The queue is then
7594 just purged into wire. There won't be any fixes for this
7595 any time soon. So, the current semantic for packet sending
7598 o If you send packet to remote host and do not force the send
7599 (the packet will be in queue) then all subsequent packets to the
7600 same remote host must also be put to the queue. Only after the
7601 queue has been purged is it safe again to force the packet
7604 o If you send all packets immediately then it safe to send
7605 any of subsequent packets through the queue, however, after
7606 the first packet is put to queue then any subsequent packets
7607 must also be put to the queue.
7609 Follow these rules and everything works fine.
7611 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Added new function silc_server_remove_clients_by_server to
7614 remove all client entries from ID list when the server connection
7615 is lost. In this case it is also important to invalidate all
7616 client entires as they hold the invalid server entry. This
7617 fixes fatal bug when server has lost connection and will reconnect
7620 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Made some sanity checks to silc_server_daemonise like to check
7623 whether the requested user and group actually exists.
7625 * Added sanity check to SKE's silc_ske_responder_finish to check
7626 that the public and private key actually is valid.
7628 * Invalidate the client's nickname when receiving Replace ID
7629 packet and the Client ID is being replaced. This means that the
7630 server will query the nickname if someone needs it (client)
7633 * Sort the ID Cache in client library when the ID Cache data
7634 has changed (needs sorting).
7636 * Do not allow for SILC client to create several connections to
7637 several servers. The client does not support windows right now
7638 and generating multiple connections causes weird behaviour.
7640 Irssi-silc client does support windows and can handle several
7641 connections without problems, see: www.irssi.org and SILC plugin.
7643 * Fixed some places where client was added to the IDList. The
7644 rule of thumb is following (in order to get everything right):
7645 If the client is directly connected local client then the
7646 `connection' argument must be set and `router' argument must be
7647 NULL to silc_idlist_add_client function. If the client is not
7648 directly connected client then the `router' argument must
7649 bet set and the `connection' argument must be NULL to the
7650 silc_idlist_add_client function.
7652 * The funtion silc_server_packet_send_local_channel actually did
7653 not check whether the client was locally connected or not. It
7654 does that now. Fixed a bug related to LEAVE command.
7656 * Fixed Remove Channel User payload parsing bug in server's
7657 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7659 * The server's silc_server_save_channel_key now checks also the
7660 global ID list for the channel as it might not be in the local
7661 list. Fixed a bug related to LEAVE command.
7663 * Is this the end of the [<unknown>] buglet that has been lurking
7664 around for a long time? A little for loop fix in server's
7665 silc_server_command_whois_parse that is used by both IDENTIFY
7666 and WHOIS command. At least, this was a clear bug and a cause
7667 of one type of [<unknown>] buglet.
7669 * WHOIS and IDENTIFY commands call the function
7670 silc_server_command_[whois/identify]_check function even if
7671 we are not router server.
7673 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7675 * Added --with-gmp configuration option. If set the GMP
7676 is always compiled in the SILC source tree. If not set then
7677 it is checked whether the system has the GMP3 installed. If
7678 it has then the GMP won't be compiled (the system's headers
7679 and library is used), if it doesn't have it then the GMP is
7680 compiled in the SILC source tree.
7682 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Changed RSA private exponent generation to what PKCS #1
7685 suggests. We try to find the smallest possible d by doing
7686 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7687 not security fix but optimization.
7689 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Added new config entry [Identity] to fork the server and run
7692 it as specific user and group. A patch from Bostik.
7694 * Imported Dotconf configuration library into lib/dotconf.
7695 This will be used to create the SILC configuration files later.
7696 It will appear in the distsribution after this commit.
7698 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * A big code auditing weekend happening. Auditing code for
7701 obvious mistakes, bugs and errors. Also, removing any code
7704 Removed files for being obsolete:
7706 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7707 inline in the file lib/silcutil/silcbuffer.h)
7709 o lib/silcutil/silcbufutil.c (the header has inline versions)
7711 Changed code to fix possible error conditions:
7713 o The buffer formatting routines now check that the destination
7714 buffer really has enough space to add the data. This applies for
7715 both buffer formatting and unformatting
7716 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7717 unformatting was changed to accomodate following rules:
7718 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7719 sent to the function while XXX_*STRING will not allocate or copy
7720 the data into the buffer. Instead it sets the pointer from the
7721 buffer into the pointer sent as argument (XXX_*STRING used to
7722 require that the pointer must be allocated already). This change
7723 makes this whole thing a bit more consistent and more optimized
7724 (note that the data returned in the unformatting with XXX_*STRING
7725 must not be freed now). The routines return now -1 on error.
7727 o Tried to find all code that use buffer_format and buffer_unformat
7728 and added return value checking to prevent formatting and
7729 especially unformatting errors and possible subsequent fatal
7732 o Changed ske->x and ske->KEY to mallocated pointers in
7733 lib/silcske/silcske.h. Fixed possible data and memory leak.
7735 o Added return value checking to all *_parse* functions. Fixed
7736 many memory leaks as well.
7738 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7739 so that buffer overflows would not happen. All code now also
7740 checks the return value as it can fail.
7742 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Added reconnection support to server if the normal server looses
7745 its connection to the router (for example if router is rebooted).
7746 The server performs normal reconnection strategy implemented
7747 to the server. Affected file silcd/server.c.
7749 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7751 * Added new packet type SILC_PACKET_SET_MODE that is used to
7752 distribute the information about changed modes (for clients,
7753 channels and clients channel modes) to all routers in the
7754 network. Updated the protocol specification accordingly.
7756 Added functions into silcd/packet_send.c and
7757 silcd/packet_receive.c: silc_server_send_set_mode,
7758 silc_server_set_mode.
7760 Added new files silcmode.[ch] into lib/silccore that implements
7761 the encoding and decoding of Set Mode Payload. Added new type
7762 SilcSetModePayload. Moved the definitions of different modes
7763 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7765 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7767 * Oops, a little mistake in server's connection authentication
7768 protocol. The protocol is not ended with FAILURE but with
7769 SUCCESS if the authentication is Ok. :) Affected file is
7772 * Implemented NICK_CHANGE notify handling in server in the file
7773 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7774 the local clients on the channel. After the changing nickname
7775 in router environment snhould work and the [<unknown>] nickname
7776 should appear no more.
7778 The silc_server_replace_id function that receives the Replace ID
7779 payload now sends the NICK_CHANGE notify type also in the file
7780 silcd/packet_receive.c
7782 * Changed WHOIS and IDENTIFY command to support the maximum amount
7783 of arguments defined in protocol specs (3328 arguments). This
7784 fixed a bug that caused problems when there were more than three
7787 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7789 * Added extra parameter, command identifier, to the
7790 silc_client_send_command so that explicit command identifier
7793 Changed that ID list routines uses specific command identifier
7794 when sending WHOIS/IDENTIFY requests to the server so that they
7795 can be identified when the reply comes back.
7797 Affected files lib/silcclient/command.[ch],
7798 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7800 * Added `sender' argument to silc_server_packet_send_to_channel
7801 to indicaet the sender who originally sent the packet to us
7802 that we are now re-sending. Ignored if NULL. Affected file
7803 silcd/packet_send.[ch].
7805 * Added some server statistics support in silcd/server_internal.h
7806 SilcServerStatistics structure and around the server code. Also
7807 send some nice statistics information when client is connecting
7810 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Fixed channel ID decoding in server's JOIN command reply in
7813 silcd/command_reply.c
7815 * Fixed braodcasting of replace ID payload to not to send it if
7816 we are standalone server in silcd/packet_receive.c.
7818 * Fixed all channel message sending routines to not to send
7819 packets to clients that has router set, since they are routed
7820 separately in the same function earlier. Affects file
7821 silcd/packet_send.c and all channel packet sending functions.
7823 * In USERS reply, res_argv[i] are not allocated, the table
7824 is allocated. Thus changed that free the table, not its
7827 * In server's whois_check and identify_check if the client is
7828 locally connected do not send any WHOIS commands - they are not
7831 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Fixed some minor bugs in client when sending WHOIS command. The
7834 arguments was in wrong order.
7836 * Removed statis function add_to_channel from server in
7837 silcd/command.c that was previously used with the joining but
7840 * Tested USERS command in router environment successfully with two
7841 routers, two servers and two clients.
7843 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * Reorganized the USERS command and command reply in client library
7846 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7847 When the command is given by user we register a pending command
7848 callback that will reprocess the command after the reply has been
7849 received from the server. When reprocessing the packet we then
7850 display the information. Thus, the USERS information is displayed
7851 now in the command callback instead of in the command reply
7852 callback. The processing of the command is same as previously
7853 when server has sent the command reply in the JOINing process.
7855 * Added to USERS command in silcd/command_reply.c to join the client,
7856 we didn't use to know about, to the channel after we've created
7857 a client entry for it. Also, for clienet we did know already still
7858 check whether it is on the channel or not and add it if not.
7860 * Removed silc_server_command_join_notify as the function and its
7863 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * Changed the client's pending command handling to the same as the
7866 server's pending command handling. It is also now possible to
7867 execute command reply functions from other command reply
7868 function as the function callbacks for commands and command
7869 replies are one and same. The pending commands are not static
7870 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7871 in client connection context. Thus, pending commands are server
7872 connection specific as it is convenient.
7874 Changed the function silc_client_command_pending and
7875 silc_client_command_pending_del and added new function
7876 silc_client_command_pending_check. Removed the
7877 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7880 * Added cmd_ident, current command identifier, to the client
7881 connection context in lib/silcclient/client.h to keep track on
7882 command identifiers used in command sending. Client's command reply
7883 function handling now supports the mandatory command identifiers.
7885 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7886 funtions in client to fully support pending command callbacks.
7888 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7889 as one of the arguments to the application in the command reply
7892 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7893 before first releasing SILC but came back. Now it is removed again
7894 and should come back nomore. The FORWARDED flag was used only
7895 by the JOINing procedure by forwarding the command packet to router.
7896 Now, the JOINing procedure has been changed to more generic (due
7897 to various router environment issues) and FORWARDED is not needed
7898 anymore for anything. The protocol specification is yet to be
7901 Now, removed silc_server_packet_forward from server and the flag
7902 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7904 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7906 * Renamed NAMES command to USERS command. The NAMES was named that
7907 due to historical reasons. Now it is renamed. Also, rewrote
7908 parts of the USERS command. The nickname list is not sent anymore
7909 by the server. Only Client ID and mode lists are sent in the USERS
7910 command. Changed this also to the protocol specification.
7912 The client now resolves the names and stuff after it receives
7913 the USERS list from the server when joining to the channel.
7915 * WHOIS and IDENTIFY commands has been changed to support multiple
7916 Client ID's per command. One can now search for multiple users
7917 in the network by sending only one WHOIS or IDENTIFY command.
7918 Changed the code and the protocol specifications.
7920 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7921 uses silc_server_command_whois_parse to parse the request. */
7923 * If normal server, do not parse the WHOIS and IDENTIFY requests
7924 before sending it to the router. Saves some time.
7926 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7928 * Fixed JOIN command on client library. Wrong number of arguments
7929 used to crash the client.
7931 * Added silc_server_channel_has_global function to check whether
7932 channel has global users or not.
7934 * Added silc_server_channel_has_local function to check whether channel
7935 has locally connected clients on the channel.
7937 * The silc_server_remove_from_one_channel now checks whether the
7938 channel has global users or not after given client was removed from
7939 the channel. It also checks whether the channel has local clients
7940 on the channel anymore. If it does not have then the channel entry
7941 is removed as it is not needed anymore.
7943 * The silc_server_notify now checks on JOIN notify whether the joining
7944 client is one of locally connected or global. If it is global then
7945 the channel has now global users on the channel and that is marked
7946 to the channel entry. Also, it now saves the global client to
7947 global list who is joining and JOINs it to the channel. This is
7948 for normal server, that is.
7950 Changed silc_server_send_notify_on_channel,
7951 silc_server_packet_relay_to_channel and
7952 silc_server_packet_send_to_channel check if we are normal server
7953 and client has router set (ie. global client) do not send the
7954 message to that client, as it is already routed to our router.
7956 * Implemented LEAVE notify type handling in silc_server_notify
7959 * Tested LEAVE command in router environment successfully. Tested
7960 with two routers, two servers and two clients.
7964 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7966 * Implemented SIGNOFF notify type handling in silc_server_notify
7969 * silc_server_remove_id now removes the client entry from all channels
7970 it has joined and thusly sends SIGNOFF notify type.
7972 * Rewrote the NAMES list generation in server by removing two excess
7973 loops. The lists are created now inside one loop.
7975 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * silc_server_remove_channel_user checks now also global list
7978 for channel and client.
7980 * silc_server_new_channel_user checks now both local and global
7981 list for channel and client. Fixed a bug in client id decoding.
7982 Used to decode wrong buffer.
7984 * silc_server_channel_message checks now both local and global
7985 list for channel entry.
7987 * Tested channel joining (hence JOIN) in router environment
7988 successfully. Tested with two routers, two servers and two
7991 * Tested channel message sending in router environment successfully.
7993 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7995 * Added silc_server_save_channel_key into server.[ch] to save the
7996 received channel key in Channel Key payload processing. It is
7997 also used in JOIN command reply handling.
7999 Equivalent function silc_client_save_channel_key added into
8000 client.[ch] into client library.
8002 * Changed JOIN command reply to send information whether the channel
8003 was created or not (is existing already) and the channel key
8004 payload. Changed protocol specs accordingly.
8006 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8007 the request was sent by ID and not by nickname. Crashed on
8010 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8012 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8013 now correctly save the received data.
8015 * silc_server_free_sock_user_data now notifies routers in the
8016 network about entities leaving the network.
8018 At the same time implemented functions silc_server_remove_id
8019 and silc_server_send_remove_id to receive and send REMOVE_ID
8020 packets. The packet is used to notify routers in the network
8021 about leaving entities. The ID removed will become invalid in
8024 * Added function silc_idlist_del_server into server. Removes and
8025 free's server entry from ID list.
8027 * silc_server_private_message function now checks, if we are router,
8028 that the destination ID really is valid ID, naturally.
8030 * In router when NEW_ID packet is received (for new client) the
8031 hash of the Client ID is saved in the ID Cache but the
8032 client->nickname is set to NULL, instead of putting the hash
8035 IDENTIFY command now also checks that client->nickname must be
8036 valid. If it is not if will request the data from the server who
8037 owns the client. Added new function
8038 silc_server_command_identify_check.
8040 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8041 to set the command to already allocated Command Payload.
8043 * Tested private message sending in router environment with two
8044 routers, two servers and two clients. Fixed minor bugs and now
8047 * Fixed segfault from client's NAMES command. Used to crash if
8050 * Forwarded packets must not be routed even if it is not destined
8051 to the receiver. Changed server code comply with this.
8053 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Added `require_reverse_mapping' boolean value to ServerParams
8056 structure. If TRUE (not default) the server will require that
8057 the connecting host has fully qualified domain name.
8059 If the reverse mapping is not required and hostname could not be
8060 found the IP address is used as hostname.
8062 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8064 * Implemented version string checking to both client and server.
8065 The check is incomplete currently due to the abnormal version
8066 strings used in development version of SILC.
8068 * Changed all command functions in server to use the new
8071 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Changed char *data to unsigned char *data in ID Cache system to
8074 support binary data as ID Cache data. Changed code to support
8075 binary data in lib/silccore/idcache.c.
8077 * Renamed silc_server_packet_relay_command_reply to
8078 silc_server_command_reply as it is normal packet receiving
8079 function. Rewrote the function to accept command replys for
8080 servers and not only for clients.
8082 * Mark remote router always as registered server if we are connecting
8083 to it. Otherwise, commands sent by the router to us are ignored.
8085 * All ID List find routines now returns the ID Cache Entry pointer
8086 as well if requested.
8088 * WHOIS command works now in router environment, tested with two
8089 routers, two servers and two clients.
8091 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8092 in router environment (as it is almost equivalent to WHOIS) but
8093 hasn't been tested thoroughly. Added new functions:
8095 silc_server_command_identify_parse
8096 silc_server_command_identify_send_reply
8097 silc_server_command_identify_from_client
8098 silc_server_command_identify_from_server
8100 * Disabled route cache adding because adding two different ID's with
8101 same IP replaces the old cache entry thus giving wrong route.
8102 The entry->router->connection is always the fastest route anyway
8103 so route cache may not be needed. Of course, new routes maybe
8104 established after receiving the ID when the entry->router->connection
8105 might not be anymore the most optimal.
8107 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Add route cache for received ID for fast routing.
8111 * Added silc_server_packet_route to route received packet on router
8112 that is not destined to us.
8114 * Renamed silc_server_get_route to silc_server_route_get.
8116 * Added id_string and id_string_len fields into SilcServer to
8117 include encoded ServerID for fast comparing without excess
8118 encoding of the ID's.
8120 * Cleaned up WHOIS command on server side. Added following static
8123 silc_server_command_whois_parse
8124 silc_server_command_whois_check
8125 silc_server_command_whois_send_reply
8126 silc_server_command_whois_from_client
8127 silc_server_command_whois_from_server
8129 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8130 arguments in command replies. All command functions should be
8131 updated to use this macro.
8133 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8135 * Minor typo fixes on command reply handling on server.
8137 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8139 * Added silc_server_command_add_to_channel internal routine to add
8140 the client to the channel after router has created the channel and
8141 sent command reply to the server.
8143 * Added generic silc_server_send_command to send any command from
8146 * Use static buffer with ID rendering instead of duplicating data.
8148 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Fixed a channel user mode bug when joining to a channel server gave
8151 everybody channel founder rights, oops.
8153 * We mark ourselves as the router of the incoming server connection
8154 if we are router ourselves. This way we can check in some packet
8155 sending functions whether it is locally connected server. For
8156 incoming router connections we put NULL.
8158 * For router sending packets locally means now always sending the
8159 packet cell wide; to local clients and local servers. For normal
8160 server sending packet locally means sending it to only local
8163 * Fixed the JOIN command to really work in router environment. If the
8164 channel is created it is always created by the router. Router is
8165 also responsible of making the initial joining to the channel,
8166 sending JOIN notify to the sending server and distributing
8167 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8168 does not exist server doesn't do anything else but forward the
8169 command to the router which performs everything.
8171 * Added silc_server_send_channel_key function to send the Channel Key
8174 * Added silc_server_create_channel_key to create new channel key. The
8175 channel key is now re-generated everytime someone joins or leaves
8176 a channel, as protocol dictates. Note: channel->key_len is the
8179 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8182 packet_receive.[ch] to separate packet sending and receiving
8183 routines. The server.[ch] now includes everything else including
8184 actual packet processing (writing and reading data) and other
8187 Renamed silc_server_private_message_send_internal to
8188 silc_server_send_private_message. The routine is still though
8189 used only to relay private messages as server does not send
8190 private messages itself.
8192 Renamed silc_server_new_channel to silc_server_create_new_channel
8193 and added new function sicl_server_new_channel that handles the
8194 incoming New Channel packet. Added also new sending function
8195 silc_server_send_new_channel to send New Channel Payload.
8197 * Added new function silc_server_notify to process incoming notify
8198 packet to the server/router. Server may then relay the notify
8199 to clients if needed.
8201 * Added new function silc_server_new_channel_user to process incoming
8202 New Channel User packet. Router will redistribute the packet and
8203 send JOIN notify to its local clients and locally connected servers
8204 if needed. Normal server will send JOIN notify to its local client
8205 on same channel when received this packet. Added also corresponding
8206 sending function silc_server_send_new_channel_user to sent the
8209 * Added boolean route argument to send_notif_to_channel and
8210 packet_send_to_channel functions to attempt to route the packet
8211 if it is TRUE and send only locally if it is FALSE.
8213 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8215 * silc_server_replace_id now broadcasts the received replace ID
8216 packet if it is not broadcast packet already. The router must
8217 broadcast to inform other routers about changed ID.
8219 * Added backpointer to server's router into SilcServer context in
8220 silcd/server_internal.h.
8222 * Fixed silc_server_packet_broadcast to send correct broadcast
8225 * The channel key is now distributed to the local client as soon
8226 as it is received from the router (in router environment) so that
8227 no other packet may be sent for the channel until client has
8230 * silc_server_remove_channel_user now broadcasts the received
8231 Remove Channel User packet if it is not broadcast packet already.
8232 The router must broadcast to inform other routers about removed
8235 * Added users field into SilcPacketContext that is a reference count
8236 of the context. One can increase the reference count by calling
8237 silc_packet_context_dup which is now changed to just increase the
8238 reference count instead of duplicating the data. The reference
8239 count is decresed by calling silc_packet_context_free that will
8240 free the data after the reference count hits zero.
8242 For now on the packet context and everything allocated into it
8243 (including the raw packet from network) must be freed by calling
8244 the new silc_packet_context_free function. Added also new function
8245 silc_packet_context_alloc that must be used now to allocate the
8246 context. This also means that if a routine is asynchronous from
8247 silc_[client/server]_packet_parse_type the packet context must
8248 be duplicated by calling silc_packet_context_dup. Otherwise it
8249 gets free'd after silc_[client/server]_packet_parse_type returns.
8250 Also, one must remember that if packet is duplicated then its
8251 reference count must be decresed by calling the free function as
8252 many times as it was duplicated.
8254 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8255 from both client and server.
8257 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Made joining to a channel working in router environment.
8261 * Cleaned up JOIN command on server side and create function
8262 silc_server_command_join_channel internal routine to make the
8265 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * Changed silc_command_pending list to SilcDList. Also, added
8268 `ident' field to SilcServerCommandPending structure to identify
8269 the reply and to call correct callback.
8271 Added silc_server_command_pending_check function to replace the
8272 corresnponding macro. The silc_command_pending list is not
8275 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8276 to set identifier to previously allocated Command Payload. It
8277 is used to set identifier for command when resending Command
8280 * Added silc_command_payload_encode_payload to encode Command
8281 Payload buffer from SilcCommandPayload structure.
8283 * Added silc_argument_payload_encode_payload to encode Argument
8284 payload buffer from SilcArgumentPayload structure.
8286 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8288 * Changed WHOIS command to support router connection on server side.
8289 The whois request is always sent to router unless the server is
8290 standalone server. After server has received the reply from the
8291 router will it send the reply to the client.
8293 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8294 broadcast received broadcast packet. The function is used only
8295 by router. The broadcast packet is always sent to the router's
8298 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8299 render given ID to printable string, for log files for example.
8301 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Made basic router to router connections working. At least they
8304 can now connect to each other but nothing really works the way
8305 they are supposed - yet.
8307 * Added new initiator token to RouterConnection configuration
8308 file in silcd/serverconfig.[ch]. It is used to tell whether we
8309 are the initiator to the remote router or whether we'll expect
8310 the other end to connect.
8312 * Moved registering of listener task to silc_server_init, hence
8313 the server starts listenning as soon as it is run, even if it
8314 does not have connections to other routers. Let's see how well
8317 * Changed default connection retry timeouts for more suitable in
8320 * Removed cipher and such arguments from silc_idlist_add_client
8321 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8322 Added new function silc_idlist_add_data to add the keys and stuff
8325 * Added SilcIDListData structure and added it to SilcClientEntry
8326 and SilcServerEntry as their first field in the structure. This
8327 way we can explicitly cast the ID entries to the SilcIDListData
8328 structure and get common data for the entries. In past, we had
8329 to first check what type of connection it is and then cast it to
8330 correct ID entry type. Now, we can directly cast the opaque
8331 pointer to the SilcIDListData (no matter what ID entry it actually
8332 is) and get the data needed.
8334 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8336 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8337 in some circumstances even if threre were timeout tasks, though not
8338 IO tasks, but tasks anyway. Now fixed.
8340 * Defined SilcServerConnection structure to hold connection specific
8341 stuff about directly connected servers and routers. The definition
8342 is currently in silcd/server_internal.h. I thought about having
8343 a bit more important role fro this struct but for now it is used
8344 only when connecting to other server (or router actually).
8346 * Added connecting retry support in server when connecting to
8347 router(s). The retry feature implement exponential backoff
8348 algorithm. Also, added SilcServerParams structure to hold default
8349 parameters for server. For now, it include these retry settings
8350 and are hard coded. After server is moded to be as Silc Server
8351 Library this structure will be more important.
8353 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8355 * Changed client librarys channel->clients table to SilcList and
8356 changed code accordingly.
8358 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8360 * Changed client's channel table to SilcList and changed code
8361 accordingly. Also changed SilcChannelClientEntry to include back-
8362 pointer to the channel so that client entry can use that structure
8363 as list as well and we have fast cross-reference to the channel.
8364 This change dramatically decreased the complexity of channel
8365 handling with client entry and vice versa (removed one extra
8366 loop when searching for channel entry from many functions).
8368 * Changed server->sim from table to SilcDList and changed code
8371 * NAMES command can now be used from user interface. It will show
8372 the user list on the channel, neatly.
8374 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8375 Code now saves realname of the user if it becomes available.
8377 * Renamed configure.in to configure.in.pre and made ./prepare
8378 script to automatically add correct version string to
8379 configure.in which it creates from configure.in.pre.
8381 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8383 * NAMES command reply now shows users mode with the nickname when
8386 * Moved silc_client_ch[u]mode[_char] functions from
8387 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8388 place sucks, they are utility functions and should be in some
8391 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8393 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8396 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Added TRQ (efficient deque and list library) into lib/trq. This is
8401 a very good list library that is currently used in the SILC. Defined
8402 SilcList API over the library because I didn't like the API very
8403 much. See lib/trq/silclist.h for the API and examples of how to
8404 use the API. Fixed various places in the code to use the new
8405 SilcList API. The SilcList is meant for lists that has a structure
8406 already defined as a list. It is not suitable to add just some
8407 context to the list (in TRQ, the context is the list actually).
8409 So, I defined SilcDList that can be used for the purpose where
8410 predefined list structure does not exit. This can be used as
8411 such list. Now some context just can be added to the SilcDList.
8412 Currently this list is not used in the SILC just yet, though there
8413 are a lot places where this can replace dynamically allocated
8414 tables and I will fix these places, later, to use SilcDList.
8415 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8416 and use TRQ internally).
8418 Also fixed some annoying warning messages that the original TRQ
8419 code generated. Also minor changes to TRQ's Makefile.in.
8421 * Added support for querying by Client ID to both WHOIS and
8422 IDENTIFY commands into server, as required by the protocol.
8424 * Removed method function pointers from SilcBuffer structure. They
8425 weren't used to anything and just increased the context size for
8426 no good reason. This change also made silc_buffer_alloc and
8427 silc_buffer_free functions inline functions.
8429 * Disabled command flooding detection support until it's fixed so
8430 that it accepts commands in but does not execute them more than once
8433 * Added silc_net_localhost(), to return local hostname, into
8434 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8435 that must be initialized before calling silc_client_init.
8437 * Added new function: silc_server_send_notify_on_channels to send
8438 notify messages to all channels client has joined. It is assured
8439 that the message is sent only once per client.
8441 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8442 lib/silcutil/silcutil.[ch] as silc_format function. The new
8443 function is generic and is used by server as well, not only by
8444 the logging routines.
8446 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8447 the provided version string was not acceptable. Added new function:
8448 silc_ske_check_version into lib/silcske/silcske.h. The function
8449 must be implemented by the application (client or server) and it
8450 does not reside in the SKE library. The function checks the version
8451 string remote end sent.
8453 * Added back pointers (to opaque context and to SilcSocketConnection)
8454 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8456 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8457 duplicate packet context structure.
8459 * Changed `notify' client operation to send same arguments as client
8460 receives from server except for ID's. ID's are mapped to correct
8461 ID entry and that is returned. Also, if channel entry is not sent
8462 by server but the notify is for channel the channel entry is sent
8463 to application (otherwise application doesn't know that it is for
8464 channel (library gets it from packet's Destination ID)).
8466 * Added silc_client_remove_from_channels into client library to
8467 remove a client from all channels it has joined to. Used when
8468 received SIGNOFF notify from server. Added also new function
8469 silc_client_replace_from_channels to replace old ID entry with
8470 new ID entry on all channels. Used when received NICK_CHANGE
8473 * Fixed ID Cache list handling in silc_idlist_get_client in
8474 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8475 to get (or query) client by ID.
8477 * Updated TODO list.
8479 * Added connection authentication status message defined by the
8480 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8481 support for these into the code in client and server side.
8483 * Added generic function silc_client_send_command to send any command
8484 with variable argument list. Application should use this function
8485 to send commands if the command functions provided by the library
8486 does not suite for the application's user interface needs.
8488 * Added new `failure' client operation. Application is notified about
8489 received failure packet if client is executing a protocol. In this
8490 case the protocol's execution has failed.
8492 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8493 is required by the protocol.
8495 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8496 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8499 * Added status flag to SilcSKE object to indicate realtime status
8500 of the SKE protocol.
8502 * Application receives now exactly same command reply arguments as
8503 the library receives from server. However, if ID is received the
8504 corresponding ID entry is returned to the application (eg. Client
8505 ID is mapped to correct SilcClientEntry entry and that is returned).
8506 Changed command_reply client operation due to this change.
8508 * Changed all ID's in commands and in command replys as ID Payloads.
8509 Change affected both client and server side codes.
8511 All ID's sent in SILC network (with execption of ID's in SILC
8512 Packet header) are sent in ID Payload to support variable length
8515 * Server now notifies nick changes and notifies all clients on
8516 the channels about the new nickname (about the new Client ID,
8519 * Implemented CMODE command to change channel modes. Supports all
8520 channel modes defined by the protocol specs except ban and invite
8521 lists. (Also, private channel key mode is supported but support for
8522 setting private channel key in client is missing, thus, this mode
8523 has no effect on client side (except that server requires that the
8524 client uses private channel key and normal channel traffic does not
8527 Also, invite mode works per se, but INVITE command does not work
8528 yet correctly, so you can set channel as invite only channel but
8529 inviting clients to the channel does not work (it is yet to be
8530 thought what's the best way to do it).
8532 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8533 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8534 Implemented CUMODE command to change user's mode on the channel.
8535 Supports all modes defined by the protocol specs.
8537 * Added NAMES command reply to return users modes on the channel.
8539 * Removed unnecessary and slow ciphers from lib/silccrypt.
8541 * Set SO_KEEPALIVE option to connection sockets by default.
8543 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8545 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8546 redefined the Notify Payload into protocol specs.
8548 * Added silc_id_payload_parse_id to get ID directly from raw
8551 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8553 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8554 accept searching by Client ID as well.
8556 * Added support for LEAVE and SIGNOFF notify types in client library.
8558 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8559 to parse ID Payload from raw data.
8561 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8563 * Added flags parameter into silc_ske_assemble_security_properties
8564 function in lib/silcske/silcske.[ch].
8566 * Changed notify client operation to fit better for notify messages
8567 sent by server. The notify payload received from server is now
8568 passed to the application (after parsing it to SilcNotifyPayload).
8569 It is application's responsibility to retrieve the arguments
8570 from the payload and show the message the way it wants. The message
8571 sent by server is implementation specific.
8573 * Changed public keys to comply with the protocol specification.
8574 Old public keys are not supported anymore and are not compatible.
8576 * Removed nickname from Channel Payload as the latest draft removed
8577 it. The client must resolve the nickname from the NAMES command
8578 reply received when it joined the channel.
8580 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8582 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8584 * Fixed some errors in protocol specification drafts.
8586 * Created lib/silccore/silcnotify.c to implement Notify Payload
8587 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8588 generic payloads described by protocol specifications. The file
8589 includes implementations for ID Payload and Argument Payload.
8591 * Changed Command Payload implementation to use the new Argument
8592 Payload. Changed command_xxxx_payload to command_payload_xxxx
8593 to comply with SILC coding conventions.
8595 * Added suppport for Argument Payload handling in Notify Payload
8596 implementation as protocol requires it. Added the new support
8597 into server and client lib as well.
8599 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8601 * Added support for multiple nicknames on same channel. [n] is
8602 added locally to the nickname if there are more than one same
8603 nicknames on the channel.
8605 * Server now sends all nicknames that matched WHOIS request.
8606 Client also shows the list received from server.
8608 * Added TOPIC command to client side. User can now set and show
8609 current topic on channel.
8611 * Added MOTD command to client and server. Also, server sends the
8612 motd when client connects to the server.
8614 * Changed version strings to comply ISO 8601.
8616 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8618 * Fixed protocol error handling in client library. It should now
8619 cope even if the SKE fails for some reason.
8621 * Made new protocol specification drafts for submitting to IETF.
8623 * Implemented TOPIC command to server in silcd/command.c.
8625 * Added two new notify types into lib/silccore/silcnotify.h:
8626 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8627 notify nickname change and topic setting/change on a channel.
8629 * API change of command_reply operation in client library. The
8630 application gets now the status type received from server as well.
8632 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8634 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8636 * Cras fixed and optimized the packet handling even further and
8637 it should work now. Minor change to the prototype of function
8638 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8640 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8642 * Added new function into lib/silcutil/silcschedule.[ch]:
8643 silc_schedule_with_fd to select() a specified fd. The function
8644 returns after timeout expires or data arrives or goes. The
8645 function is used by packet routines to wait that all data is
8646 received from network.
8648 * Fixed data reading from network in lib/silccore/silcpacket.c.
8649 The code now assures that all data is read from the fd and then
8650 continues packet processing. This was a bug fix since the code
8651 used to drop some data in some circumstances.
8653 * Added new function into lib/silcclient/client.[ch]:
8654 silc_client_start_key_exchange to start key exchange after
8655 connection has been established to server. The code internally
8656 now uses this funtion but its main purpose was to provide it
8657 for applications that perform their own connecting. After
8658 application has created a connection it merely calls this
8659 function to start the key exchange between client and server.
8660 The library takes care of everything else after that.
8662 Updated also lib/silcclient/README to explain the usage of
8665 * Do not send to application information that connection has
8666 been established. Application gets notified it by connect
8669 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8671 * Applied cras's patch to add silc_schedule_one function. The
8672 function runs scheduler once and returns.
8674 * Fixed the scheduler after cras messed it up. The timeout
8675 handling works now as it's supposed to work.
8677 * Added into lib/silccore/ silcnotify.h to include notify
8678 message types support. Changed silc_server_send_notify*
8679 functions, in server.[ch], to support those new notify types.
8680 Added the support for the notify types into client library,
8681 as well. Added new notify client operation into ops.h in
8684 * Changed silc_server_packet_send_to_channel to send normal
8685 packets instead of just channel message packets. The function
8686 is now used to send the notify packets to channels. It is not
8687 used to send channel message packets anymore, as server never
8690 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8691 va_arg()s as it seems to require it nowadays. I guess, if SILC
8692 is compiled with older va_arg() the new code should work anyway.
8694 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8696 * Splitted core library. Core library (lib/silccore) includes
8697 now only SILC protocol specific core (and common) components.
8698 Created new utility library (lib/silcutil) that includes more
8699 generic purpose stuff. The stuff for util library was taken
8700 from the old core library. This was minor and easy split.
8702 * Created SILC Client Library (lib/silcclient) that includes
8703 implementation of the SILC client without user interface. This
8704 was major move from silc/ directory. The code has been changed
8705 so that it is transparent towards the user interface. The
8706 silc/ directory includes now the same user interface as before
8707 and it uses the new client library. Read lib/silcclient/README.
8708 Basicly, the client library performs everything else related
8709 to SILC except user interface handling. Also, configuration
8710 files are considered to be part of user interface and library
8711 does not handle them.
8713 This change also changed a lot of structures, function naming etc.
8714 Most important change was that SilcClientWindow object was
8715 renamed to SilcClientConnection in the client library. Created
8716 also new file lib/silcclient/ops.h. Also added new files
8717 silc/local_command.[ch] and silc/client_ops.[ch].
8719 All these changes were made to make it easier for user interface
8720 designers to create what ever user interface for the SILC client
8723 It is also expected that the server will be moved to lib
8724 directory as well and SILC Server Library will be created;
8725 sometimes in the future.
8727 * Removed Local commands from lib/silccore/silccommand.h as
8728 they are application specific and new client library does not
8729 handle any of those anymore.
8731 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8732 old client implementation in silc/.
8734 * Added support for callback functions in SILC_LOG_* macros.
8735 Application can now set its own callbacks that will be called
8736 instead of using the default functions that will always print
8737 the debug messages to stderr (or stdout). Also, debugging can
8738 now be disabled by setting silc_debug to FALSE and re-enabled by
8739 setting it to TRUE. Note, that logging will still work even
8740 if debugging is disabled.
8742 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8743 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8744 silc_log_reset_debug_callbacks.
8746 * To enable debugging in silc client one must give now -d
8747 option on command line.
8749 * Changed silc_schedule_init to automatically allocate task queues
8750 if they are not allocated before calling it.
8752 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8754 * Added GMP 3.1 into math library.
8756 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8758 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8759 a channel in SILC network. The packet is used by servers and
8760 routers to notify other routers that user has left a channel.
8761 This little feature was missing until now. Added the feature
8762 to protocol specification as well.
8764 Added functions: silc_server_send_remove_channel_user and
8765 silc_server_remove_channel_user into server.[ch].
8767 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8768 lib/silccore/silcpacket.h. However, they are not implemented
8771 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8773 * Fixed joining to a channel and sending channel messages
8774 between server and router. The channel message sending should
8775 now work inside a cell.
8777 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8779 * Fixed the private message sending between server and router.
8780 The private message sending should now work inside a cell.
8782 * Added silc_server_replace_id into server.[ch] to replace
8783 existing ID in the SILC network.
8785 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8786 and silc_idlist_replace_server_id into idlist.[ch] in server.
8788 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8790 * Fixed the server to server connections. Server can again now
8791 connect to router. Router to router connections probably does
8794 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8796 * Added dynamic protocol registering support. Now protocols can
8797 registered and unregistered on the fly. Patch by cras.
8799 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * Added lib/contrib directory to hold routines that some platforms
8802 don't have but are needed by SILC.
8804 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8805 into lin/contrib to provide getopt() and getopt_long() for
8806 those who don't have it.
8808 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8810 * Added AWAY command to client. When away message is set and
8811 client receives a private message packet the client automatically
8812 replies to the sender with the away message.
8814 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8815 bug seemed to be the cause of recent problems when compiling
8818 * Added version detection support to SKE protocol specification
8819 and added the new changes to the SKE implementation as well.
8820 There were other minor changes in the SKE protocol as well.
8822 Many changes in lib/silcske/silcske.[ch] and in
8823 lib/silcske/payload.[ch].
8825 * Added ^U functionality, clear input line. Patch from cras.
8827 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8829 * Mainly small bugfixes on core library. Fixed some debugging
8830 logging and buffer overflow in silclog.c.
8832 * Updated config.sub and config.guess on the distribution tree.
8834 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8836 * Added command lagging support in server. Client may execute
8837 commands now only once in two seconds.
8839 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8841 * Optimized packet reception. MAC computation and checking is now
8842 also more optimized. A lot previously duplicated code is now
8843 used as generic by both client and server.
8845 * Fixed key pair generation in clientutil.c
8847 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8849 * Added into lib/silccore/silcbufutil.[ch] new function;
8850 silc_buffer_realloc.
8852 * Moved generic packet sending/encryption functions to
8853 lib/silccore/silcpacket.[ch] from client and server. Some
8854 rewriting of the functions.
8856 * Moved all generic packet reception/decryption functions to
8857 lib/silccore/silcpacket.[ch] from client and server. The
8858 packet processing is now much cleaner in both client and server.
8859 These were major changes in both client and server.
8861 * Created many common functions in server to do packet sending.
8862 Previously code were duplicated a lot, this has been removed
8865 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8867 * Rewrote major parts of the ID cache system. Don't know
8868 whether it is better now or not but at least the API is more
8871 * Major rewrite on ID cache stuff on client because of the ID
8872 cache API changes. Added idlist.c to client.
8874 * Also major rewrite on ID cache stuff on server as well.
8875 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8876 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8877 in hand, instead they are all put into the ID cache system now.
8878 All server_idlist_* routines uses ID cache now instead of
8879 traversing its own lists (those lists does not exist anymore).
8880 SilcIDList though still exists. Also, SilcXXXEntry's are
8883 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8885 * Finally made the SKE implementation compliant to the protocol
8886 specification. All mp integers are now binary encoded as
8887 opposed being HEX encoded.
8889 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8892 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8893 functions: silc_[encode/decode]_pem. Also added function
8894 silc_encode_pem_file to PEM encode with newlines ('\n') for
8897 * SILC public keys are now encoded either PEM or binary. Same
8898 option is for private keys as well. By default private keys
8899 are binary encoded and public keys PEM encoded. Silly HEX
8900 encoding were removed.
8902 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8903 function to create fingerprints.
8905 * Fixed a bug in SHA1; does not change the original data anymore.
8907 * Partly implemented INFO command on client and server side.
8908 Fixed CLEAR command. Changes to SERVER command; show current
8909 server(s) when giving command without arguments. Added
8910 VERSION command to client.
8912 * Added check to server that unregistered connections cannot
8913 execute commands (unless it is specificly allowed).
8915 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8917 * Fixed screen refresh.
8919 * Fixed channel joining bug from client. On some circumstances
8920 client tried to join to a channel it had already joined.
8922 * Added public key verification process into client's protocol.c.
8923 The client now verifies the public key from user and saves
8924 it into ~./silc/serverkeys/ directory.
8926 Added into: clientutil.[ch]: silc_client_verify_server_key.
8928 * Changed SKE protocol's silc_ske_initiator_finish function
8929 to accept callback function that verifies the received public
8930 key. Removed old silc_ske_verify_public_key function.
8932 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8934 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8935 silc_pkcs_private_key[_data]_set.
8937 * Made the password and public authentication more cleaner in
8938 server's protocol.c.
8940 * Removed historic and obsolete protocol `channel_auth' from
8941 both client and server.
8943 * Removed wrong way of sending command status messages from
8944 server to client in server's command.c. The old way violated
8945 protocol specification.
8947 Changes to silccore/silccommand.[ch]: removed
8948 silc_command_encode_status_payload -> not needed anymore,
8949 changed silc_command_encode_payload_va to accept extra
8950 argument on variable argument list. The argument type must
8951 now be provided to the function. Also, added new function:
8952 silc_command_encode_reply_payload_va which is same as
8953 normal command_encode_payload_va except command status type
8954 is provided as extra argument.
8956 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8958 * Added ~./silc directory handling. The directory includes the
8959 public and private keys for the client.
8961 Added silc_client_check_silc_dir, silc_client_create_identifier
8962 and silc_client_load_keys.
8964 * Implemented SILC protocol compliant public key. Added public
8965 and private key saving to and loading from files.
8967 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8968 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8969 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8970 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8971 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8973 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8974 silc_pkcs_load_[public/private]_key.
8976 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8978 * Added silc_server_get_route (route.[ch]) to get connection
8979 data for the fastest route for given ID.
8981 * Implemented INVITE command on client and server. The command
8982 were re-defined in the SILC Protocol Specification and the
8983 implementation now complies with the specification.
8985 * Implemented PING command on client and server.
8987 * Implemented NAMES command on client and server. The server side
8988 supports currently only normal server not router server yet.
8989 Some changes to NAMES definition in SILC protocol specification.
8991 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8993 * Implemented LEAVE command on client and server.
8995 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8996 again. This change was made to the protocol as well. Server
8997 should not violate the protocol specification anymore.
8999 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9001 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9002 was tested. SOCKS4 was not but should work anyway.
