1 Sun Aug 4 13:23:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * More fixed for not having purge timeout for global clients
4 that are on channel. Affected files silcd/command_reply.c
7 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 * Do not process commands if the sock->user_data is NULL.
10 Affected file silcd/command.c.
12 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
14 * Fixed buffer overflow and security problems (loosing bits
15 in CFB encryption) in SILC RNG. Problems reported by
16 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
18 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
20 * Added yet more checks that client is not expired on global
21 list if it is on channels. Affected file is
22 silcd/command_reply.c.
24 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Merged c0ffee's MIME signal patch which adds support for
27 sending also MIME messages in Irssi SILC Client, and handling
28 received MIME messages in a signal (and perhaps doing something
29 to non-textual MIME messages).
31 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Fixed pending command deletion in server and client library
34 to check the whole list instead of breaking after first found.
35 The affected files are silcd/command.[ch] and
36 lib/silcclient/command.[ch].
38 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
40 * Return NO_SUCH_CHANNEL error in USERS for channel that is
41 secret or private, otherwise it's possible to find out
42 whether a secret channel exists or not. Affected file
45 * If CMODE change fails during the mode setting, assure that
46 the old mode mask is set for the channel back. Affected
49 * Fixed passphrase saving on +a channel on normal server
50 after successful JOIN command. Affected file silcd/command.c.
52 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
54 * Remove server/router operator privileges in DETACH command,
55 since it's possible to resume to server where these
56 privileges would not be allowed for the client. Affected
59 * Do not set to wait for backup in rehash of the server.
60 Affected file silcd/server.c.
62 * Do not check listener sockets when counting how many
63 socket connections we have. Affected file is
66 * Do not announce disconnected clients that are remaining
67 in history (for WHOWAS). This is because SIGNOFF notify
68 for these has been sent earlier already. Affected file
71 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
73 * Buffer overflow with CUMODE command's mode->mode character
74 conversion. Reported by Ville Räsänen. Affected file
75 lib/silcutil/silcutil.c.
77 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Allow heartbeat packets to go disabled connections anyway.
80 Affected files silcd/server.c and silcd/packet_send.c.
82 * Do not broadcast New Channel packets with List flag set
83 in the packet to backup routers. The router must check
84 for the correctness of the packets before sending them.
85 It is possible that router will have enforce Channel ID
86 change and this would cause desync in the backup router.
87 Affected file silcd/packet_receive.c.
89 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
90 are handled in list parsing. They are not list packets
91 anymore. Affected file silcd/packet_receive.c.
93 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
95 * Stop waiting for backup router through the timeout, not
96 directly after backup router has arrived. Affected file
99 * Do not re-create channel keys and send them when removing
100 clients in server shutdown. Affected files are
101 silcd/server_internal.h and silcd/server_util.c.
103 * Notify distribution to backup routers was missing from
104 the silc_server_send_notify_dest function which caused
105 desyncing problems with backup router. Affected file is
108 * The client's channel removing was working wrong on
109 backup router. It assumed that it doesn't know global
110 information but backup router does know. For this reason
111 it could remove channel when it wasn't supposed to do that.
112 Affected file silcd/server.c and silcd/server_util.c.
114 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
116 * Stop for a couple seconds after badkup router has become
117 primary router. Affected file silcd/server.c.
119 * Added silc_server_remove_servers_by_server, which is used
120 to remove servers originated from some other server. Also
121 clients of those servers can be removed too. Affected file
122 silcd/server_util.[ch].
124 * When removing clients after a server has signed of remove
125 also all servers behind that server (unless they are known
126 to be available locally), and send SERVER_SIGNOFF for each
127 of the server separately. Also the signed off clients are
128 sent now separately per signed off server. The affected files
129 are silcd/server.c and silcd/server_util.[ch].
131 * All servers added with silc_idlist_add_server must always
132 have both "router" and "connection" pointers set. Otherwise,
133 bad server entries may be left around in the cache.
134 Affected file silcd/command_reply.c.
136 * Do not create the channel key in NEW_CHANNEL packet
137 processing if the channel is empty. Affected file
138 silcd/packet_receive.c.
140 * Completed backup router support for standalone routers.
141 Supports also servers in the cell that do not use the backup
144 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Fixed a bug in silc_string_regexify which did not add '^'
147 at the start of each string, and thus the matching was
148 not explicit. For example ban list iikone@*!*@* would
149 match also "priikone", which is wrong, it would have to be
150 *iikone@*!*@* to match also "priikone". Affected
151 file lib/silcutil/unix/silcunixutil.c.
153 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Enable all local server connections before updating client
156 caches when we've become backup router. Otherwise, signoff
157 packets may not reach the clients. Affected files are
158 silcd/server.c and silcd/server_util.[ch].
160 * Fixed a bug in version string parsing which could crash
161 the program with specially formatted version string.
162 Bug reported and patch provided by Ville Räsänen. Affected
163 file lib/silcutil/silcutil.c.
165 * Handle the disconnection immediately when DISCONNECT
166 packet is received in server. Affected file silcd/server.c.
168 * Primary router now waits a short time (10 seconds) for
169 backup router connection before accepting any other
170 connection (except local). Affected file silcd/server.c,
173 * Fixed a crash in client libary in NICK_CHANGE notify when
174 NICK_CHANGE arrived for client entry we are resolving
175 currently. Affected file lib/silcclient/client_notify.c.
177 * Call the sconn->callback completion even if error had
178 occurred. Start reconnecting always if connection to
179 primary router fails during backup router protocol.
180 Affected files silcd/server.c and server_backup.c.
182 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Added functions silc_server_send_opers and
185 silc_server_send_opers_notify to send packets stricly
186 to operators. Added macro SILC_SERVER_SEND_OPERS macro
187 to send variable argument notify to operators.
188 Affected files silcd/packet_send.[ch] and silcd/server.h.
190 * Removed UMODE rights checking with UMODE_CHANGE notify.
191 Affected file silcd/packet_receive.c.
193 * Server/router operator now receives notify when network
194 switches to backup router and when it resumes the use of
195 primary router. Affected file silcd/server.c and
196 silcd/server_backup.c.
198 * Fixed the updating of client information after backup
199 resuming protocol is over; update all except local clients
200 to the new primary router. The affected file is
203 * Added support for closing active connections in rehash
204 that were unconfigured by the user. Supports currently
205 closing server and router connections. Affected file
208 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
210 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
213 is NULL since seems that on some platforms NULL is allowed
214 and on some it's not. Fallback encoding is used instead.
215 Affected file lib/silcutil/silcstrutil.c.
217 * Fixed statistics updating for incoming server connection
218 which could cause problems when re-connecting. Affected
221 * Preliminary backup router support for standalone router
222 added. Affected files in silcd/.
224 * Mark server connections in backup router disabled before
225 and after backup protocol. Affected file is
226 silcd/server_backup.c.
228 * Added support for reconnecting to remote server connection
229 even if the protocol fails, and if the configuration wants
230 us to keep trying to connect anyway.
232 Server connection is not allowed to backup router if
233 backup router does not have connection to primary router yet.
235 Affected file is silcd/server.c.
237 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Added silc_client_udpate_server function to update changed
240 server info. Affected file lib/silcclient/idlist.[ch].
242 * Added check for server entries that are being resolved when
243 notify is received. If being resolved, handle the received
244 notify only after it's resolved so that all notifys are
245 handled in same order as received from the server.
247 Added similar resolver check to channel entries. Every
248 notify that cause resolving of any information that affects
249 channel entry marks the channel entry in waiting state.
250 After whatever resolving is over the waiters are signalled
251 and only then the notifys are handled in the same order
252 as delivered from the server.
254 Affected files are lib/silcclient/idlist.[ch], and
257 * Fixed KILLED notify handling in normal server. Affected
258 file silcd/packet_receive.c.
260 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
261 is locally connected, or was locally connected (but may
262 be detached and connection is not active). Added also
263 SILC_IS_LOCAL for checking this status. Affected files
264 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
265 silcd/server.c and silcd/server_internal.h.
267 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Don't send or handle TOPIC_SET if topic is already set and
270 is same as being set. Affected files silcd/command.c and
271 silcd/packet_receive.c.
273 * Fixed CMODE change rights checking to work correctly when
274 removing modes by operator. Affected file is
277 * Fixed some handling with New Channel packet in router and
278 fixed some CMODE_CHANGE notify handling in server and router.
279 Affected file is silcd/packet_receive.c.
281 * Changed "disconnect" client operation to include the
282 reason of the disconnection and optional disconnection
283 message. Affected file lib/silcclient/silcclient.h.
285 * Made the compilation of lib/contrib/ stuff conditional.
286 Affected files configure.in.pre, lib/contrib/Makefile.am.
288 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
290 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
291 to the sender of the notify too, to avoid situation where two
292 notifys are in the network at the same time going to oppsite
293 directions. Affected file silcd/packet_receice.c.
295 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
297 * Delete the client from channel even if the cilent->id is
298 NULL. It was possible that client was deleted without
299 removing from channels (theoretically at least). Affected
300 file silcd/server.c and silcd/server_util.c.
302 * Free the client data too when resuming is not successful.
303 Affected file silcd/packet_receive.c.
305 * Merged some code from c0ffee's silc-plugin. Affected files
306 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
308 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
309 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
310 to the primary router connection, the other one returns
311 TRUE if packet must be broadcasted to network.
313 * All notifys that are destined to primary router (to network)
314 are now automatically sent to backup routers even if the
315 router is standalone (and has backup router). Affected files
318 * Added --without-irssi and --without-silcd configuration
319 options for disabling the compilation of these applications.
320 Affected file configure.in.pre and prepare.
322 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
325 UTF-8 encoding and decoding. Added also new encodings
326 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
328 Added also SILC_STRING_LANGUAGE which is language and charset
329 specific encoder and decoer for those platforms that support
330 iconv(). It can convert the UTF-8 to and from the locale
331 specific character set.
333 Affected file lib/silcutil/silcstrutil.[ch].
335 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
337 * Added function silc_get_command_name to the file
338 lib/silcutil/silcutil.[ch].
340 * Improved the server debug output a bit. Affected files are
343 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
345 * Save the channel passphrase when received succesful JOIN
346 command reply from router, on normal server. Otherwise
347 joinig +a channels from normal server is not possible.
348 Affected file silcd/command.c.
350 * Fixed a bug in TOPIC_SET notify handling. The notifier
351 may be other than client too, like server or channel.
352 It expected it to always be only client and ignored the
353 notify. Affected file silcd/packet_recieve.c.
355 * Removed some (unnecessary) debug printing from
356 lib/silccore/silcid.c and lib/silccore/silcargument.c.
358 * Do not force CMODE_CHANGE when server is announcing new
361 Router announces stuff only after server reannounces channel
362 after CHANNEL_CHANGE notify.
364 These fixes optimizes the announcing procedure, and perhaps
365 fixes some problems too. Affected file silcd/packet_receive.c.
367 * Fixed SERVER_SIGNOFF sending to local clients. It was
368 totally broken and sent the notify to all local clients,
369 instead of only to those that was on same channel as the
370 signing off clients. Affected file silcd/server_util.c.
372 * Added -D option to server. It can be used to give debug
373 level. The levels are from 0 - 99, and are predefined for
374 smooth server debugging. (see silcd.c for the predefined
375 levels). Affected file silcd/server.c.
377 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
379 * Fixed a bug in Irssi SILC client to close the connection
380 properly when disconnecting from server. Affected file
381 irssi/src/silc/core/client_ops.c.
383 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
385 * When authenticating as founder during JOIN command, check
386 that the one authenticating becomes the only founder on the
387 channel. Affected file silcd/command.c.
389 * Better checking for founder mode setting when CUMODE_CHANGE
390 notify is received. Affected file silcd/packet_receive.c.
392 * Close all connections when shutting down the server by sending
393 DISCONNECT packet. Close all listeners too when shutting
394 down the server. Affected file silcd/server.c.
396 * Handle DISCONNECT packet correctly in client library by
397 calling the "disconnect" client operation. Affected file
398 lib/silcclient/client.c.
400 * Handle local errors correctly during resuming. Affected
401 file lib/silcclient/client.c.
403 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
405 * The log file is not dupped internally anymore in
406 lib/silcutil/silclog.c. Fixed memory leaks too.
408 * The scheduler now dispatches all pending timeout tasks
409 when it is uninitialized with silc_schedule_uninit.
410 Affected file lib/silcutil/silcschedule.c.
412 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Added --enable-stack-trace option to configure. Added
415 memory allocation stack trace support. Added files
416 lib/silcutil/stacktrace.[ch]. Affected files are
417 lib/silcutil/silcmemory.[ch].
419 * Fixed memory leaks from libraries and server. Affected
420 files around the tree.
422 * Reverted back a fix made to CUMODE which broke it.
423 Affected file silcd/command.c.
425 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
428 core library, and implemented it. All textual messages SHOULD
429 use this flag and the message MUST be UTF-8 encoded.
430 All text messages sent by Irssi SILC client are now UTF-8
431 encoded (regardless whether the terminal supports UTF-8 or not).
432 Affected files are lib/silccore/silcchannel.h,
433 irssi/src/silc/core/silc-servers.c, silc-channels.c and
436 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Added lots of new statistics updating that was missing from
439 the server and router code. Affected files in silcd/.
441 * Sending SIGUSR1 signal to server now dumps the current
442 server statistics into /tmp directory. Affected file is
445 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
446 the SILC Hash Interface also. Added new functions
447 silc_hash_get_name, silc_hash_init, silc_hash_update and
448 silc_hash_final. Affected file lib/silccrypt/silchash.c.
450 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
452 * Added some better info printing for client during connecting.
453 Affected file silcd/server_util.c.
455 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
456 to silence a user on a channel. Affected files are
457 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
458 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
459 and silcd/packet_receive.c.
461 * Fixed a fatal bug in handling of malformed command payload.
462 Affected file silcd/command.c.
464 * Fixed a double free when announcing channel users to router.
465 Affected file silcd/server.c.
467 * After successful authentication to channel founder mode, check
468 that there isn't anyone else with founder mode on the channel.
469 The one that authenticated will become founder and anyone
470 else is demoted. Affected file silcd/command.c.
472 * Added error printing of any error that has occurred during
473 any command in client library. Affected file is
474 irssi/src/silc/core/client_ops.c.
476 * Removed some error printing from the client library and left
477 it for the application to worry (from the error status it
478 receives in 'command' client operation. Affected file is
479 lib/silcclient/command.c.
481 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
483 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
484 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
485 Starting key agreement with itself is denied. Affected file
486 is lib/silcclient/client_keyagr.c.
488 * Fixed some error checkings from the SFTP library which caused
489 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
490 and lib/silcsftp/sftp_util.c.
492 * Added new "debug" and "debug_string" settings to Irssi SILC
493 client which can be used to print runtime debugging on the
494 Irssi's screen. Available when compiled with --enable-debug
495 option. Affected file irssi/src/silc/core/silc-core.c.
497 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
499 * Fixed a missing variadic parameter in a function call that
500 caused server crash when a non-allowed connection arrived.
501 Reported by Richard Becker. Affected file silcd/server.c.
503 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
505 * Added WATCH list sending to backup routers from router.
506 The WATCH command is sent by the router to the backup
507 router. Affected file silcd/command.c.
509 * Mark the backup_router flag for RouterConnection entry
510 if the backup router stuff is defined in the config file.
511 Affected file silcd/serverconfig.c.
513 * Fixed some backup data sending around the code to work better
514 if the router is standalone router. Not all places were fixed.
515 Affected file silcd/packet_receive.c, silcd/packet_send.c,
518 * Fixed the router connecting when connecting to multiple
519 routers. It ignored every other router except the first
520 one. Affected file silcd/server.c.
522 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Made the private key generation after expiration optional.
525 If not created after expiration the old key will re-expire
526 at a later time (and thus key pair is not necessary to
527 change). Affected file irssi/src/silc/core/clientutil.c.
529 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
531 * The length arguments in bind() and connect() were wrong
532 and fixed now to used SIZEOF_SOCKADDR in the
533 lib/silcutil/unix/silcunixutil.c.
535 Tue Jun 4 18:36:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Fixed detach timeout handling to use Client ID and not
538 the actual client entry which may be freed in the callback.
539 Affected file silcd/command.c.
541 Thu May 30 15:53:45 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
543 * Merged c0ffee's multiple interface support patch.
544 Affected files in silcd/.
546 Wed May 29 18:08:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
548 * Cleanup keys properly. Affected file is
549 irssi/src/silc/core/clientutil.c.
551 Tue May 28 20:11:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
553 * Display the user mode on the status bar. Affected file
554 irssi/src/silc/core/silc-expandos.c.
556 Tue May 28 13:56:26 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
558 * If private message key is not set, but the flag is set in
559 the packet, ignore the packet since it cannot be decrypted.
560 Affected file lib/silcclient/client_prvmsg.c.
562 Thu May 23 12:00:14 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
564 * When resuming client, remove the old client entry from
565 the watcher list too. Affected file silcd/packet_receive.c.
567 * Do not allow normal server to force founder mode away
568 from router if the founder mode is already set. Affected
569 file silcd/packet_receive.c.
571 * Remove the client entry with watch notify types with short
572 timeout, and not directly, so that other notifys can be

1083 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1084 lib/silcclient/client_notify.c.
1086 * Added the killer's client ID to the KILLED notify and added
1087 it to protocol specs and implemented it to client and server.
1088 Protocol TODO #13. Affected files are silcd/command.c,
1089 silcd/packet_receive.c, packet_send.[ch],
1090 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1091 The killer's client entry is now returned to application in
1092 the `notify' client operation.
1094 * Fixed the Max Argument fields that had too large value set
1095 in the protocol specs. Protocol TODO #14.
1097 * Added the LEAVE command reply to return the ID of parted
1098 channel. Updated protocol specs and implemented it to the
1099 client and server. Protocol TODO #15. Affected files are
1100 silcd/command.c, lib/silcclient/command_reply.c. The channel
1101 entry is now returned to application in the `command_reply'
1104 * Rewrote the version SKE version checking in client libary
1105 and in server to use the silc_parse_version_string. Affected
1106 files are lib/silcclient/protocol.c, silcd/protocol.c.
1108 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1109 commands that was missing it, and updated protocol specs and
1110 the server implementation. Protocol TODO #10. The affected
1111 file is silcd/command.c.
1113 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1114 generic reply to a generic request (REQUEST flag), and
1115 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1116 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1117 to define the payload for DATA flag. Added the flags to
1118 the implementation. Protocol TODO #9. Affected file is
1119 lib/silccore/silcchannel.h.
1121 Changed the client library to return the message length
1122 to application as well in the channel_message and private_message
1123 client operations. Affected files are
1124 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1125 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1126 and lib/silcclient/client_ops_example.c.
1128 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1129 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1130 the channel. Updated protocol specs and impelemented this
1131 to client and server. Protocol TODO #6. Affected files are
1132 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1133 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1135 Added new options m and M to CMODE command in Irssi SILC
1136 client to set these modes.
1138 * Deprecated all administrative commands from SILC protocol
1139 since they are highly implementation specific commands.
1140 Updated protocol specs. Moved the old commands in
1141 implementations to private range of command types. Affected
1142 files are silcd/command.c, lib/silcclient/command.c and
1143 lib/silcclient/command_reply.c. Protocol TODO #8.
1145 * Fixed a bug in server where sending unknown command crashes
1146 the server. Affected file silcd/command.c.
1148 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1150 * Added SILC_PROTOCOLVERSION macro to check protocol version
1151 of a socket connection. The affected file is
1152 lib/silcutil/silcsockconn.h.
1154 * Added better error logging in rekey protocol. Affected file
1157 * Do not check public key types in SKE during rekey. Affected
1158 file lib/silcske/payload.c.
1160 * Fixed the rekey protocol with PFS, which was totally broken.
1161 Affected file silcd/protocol.c.
1163 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1165 * Some client implementations quit network by doing first LEAVE
1166 and then immediately SIGNOFF (like Bombyx). We now do check
1167 after a short time after LEAVE notify and check whether the
1168 client is still valid after LEAVE, and if not we remove it from
1169 cache. Affected file is lib/silcclient/client_notify.c.
1171 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1173 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1174 it's good not to have security holes here.
1176 * Fixed a negative refcount situtuation for the config context.
1177 Affected file is silcd/serverconfig.c.
1179 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1181 * ROBOdoc documented lib/silcutil/silcutil.h.
1183 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Optimized even more the SilcPacketContext structure. Now
1186 totally saved 16 bytes of memory per context after optimization.
1187 Affected files are lib/silccore/silcpacket.[ch].
1189 * Made strict checks for valid SILC IDs. Affected file is
1190 lib/silccore/silcid.c.
1192 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1194 * Changed the object argument for silc_cipher_register,
1195 silc_hash_register, silc_hmac_register and silc_pkcs_register
1196 to const. Affected files are lib/silccrypt/silccipher.[ch],
1197 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1199 * Changed the silc_get_username and silc_get_real_name to
1200 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1202 * Fixed the Irssi SILC Client to use the silc_get_username and
1203 silc_get_real_name insted of glib routines since the glib
1204 routines only corrupt stack. Fixes the Irssi SILC to work in
1205 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1207 * Fixed the Irssi to not use g_get_home_dir since it crashes
1208 or returns garbage on cygwin and corrupts stack. Added function
1209 get_home_dir to Irssi routines. Affected files are
1210 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1212 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Made some structure optimizations. SFTP memory FS MemFSEntry
1215 entry structure. Optimized SilcTask structure. Optimized
1216 SilcPacketContext structure.
1218 Affected files lib/silcsftp/sftp_fs_memory.c,
1219 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1221 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1223 * And yet again reverted back the config thing since Johnny
1224 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1227 * Fixed memory leaks from config object. Affected files are
1228 silcd/serverconfig.[ch].
1230 * Added support for adding new connections to the server in rehash.
1231 After rehash they take effect.
1233 Added support for changing the maximum allowed connections in
1234 rehash. The number can grow but going smaller is not supported.
1236 Added function silc_server_num_sockets_by_remote to the
1237 silcd/server_util.[ch].
1239 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1241 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1243 * Added preliminary checking during config parsing for a valid
1244 public/private key and removed further checks in the code.
1245 Affected files are silcd/serverconfig.[ch], server.c.
1247 * Moved functions silc_server_drop() and silc_server_daemonise()
1248 from server.c to silcd.c since they are stricly related to
1249 the application activity.
1251 * Reverted a small part of the automatic ref/unref since
1252 it caused a double unref in some situations. Affected
1253 files are silcd/silcd.[ch], server.c, serverconfig.c.
1255 * Added some .cvsignore files in the lib directory.
1257 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1259 * Fixed silc_net_gethostbyaddr to correctly resolve by
1260 address. Affected file lib/silcutil/silcnet.c.
1262 * Fixed the notify relaying to client. The HMAC to be used
1263 with relayed packets ws wrong and caused decryption failure
1264 at the client end. Affected file is silcd/packet_receive.c.
1266 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Created new branch silc_protocol_1_0_branch.
1270 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1272 * Changed the silc_server_config_* routines to be SilcServer
1273 independent. They are now officially application specific code
1274 and not part of generic server implementation. Affected files
1275 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1277 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * Added automatic referencing of config context in the
1280 silc_server_config_alloc, and automatic unreferencing in the
1281 silc_server_config_destroy. Affected files are
1282 silcd/serverconfig.[ch], silcd/silcd.c.
1284 * Fixed the silc_log_quick handling in the logging routines.
1285 It didn't log quickly when it was TRUE. Affected file is
1286 lib/silcutil/silclog.c. Also the flush delay was set even
1287 if it was 0 in config file. Affected file is
1288 silcd/serverconfig.c.
1290 * Added support for changing key pair of the server in rehash.
1291 Affected file silcd/server.c.
1293 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1295 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1296 too early, before getting the channel entry. Affected file
1297 is silcd/packet_receive.c.
1299 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1301 * Added functions silc_server_config_[ref/unref], these are used
1302 to prevent that the config object is destroyed.
1304 No longer directly affect global variables silc_log_quick and
1305 silc_log_delay, they are first cached inside the config object
1306 and then applied with silc_server_config_setlogfiles().
1308 silc_server_config_set_defaults() is now internal to
1309 serverconfig.c, there are no reasons to show this internal stuff
1312 Affected files are silcd/serverconfig.[ch].
1314 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1315 fprintf's to stderr, since some code may be executed again after
1316 the server went into the background. Affected files are
1319 * Added rehash support. Added function silc_server_rehash() that
1320 will perform all the basic tasks of the rehashing procedure.
1322 * Added command line option `-x, --hexdump'. This will enable the
1323 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1324 The option `--hexdump' implies `--debug'.
1326 * Fixed a bad bug in the logging APIs (silcutil library) where
1327 the application would crash after calling silc_log_reset_all().
1329 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Fixed the KICKED notify handling in client library to
1332 correctly remove the channel and all entries from the
1333 channel when I was kicked. This bug crashed the client.
1335 Fixed yet another but in KICKED notify handling to remove
1336 the kicked client correctly from the channel.
1338 Affected file is lib/silcclient/client_notify.c.
1340 * Fixed a minor bug in looking up correct client entry
1341 in KICKED notify in server. Affected file is
1342 silcd/packet_receive.c.
1344 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1345 sources correctly to distribution. Fixes --with-gmp option.
1347 * Removed the manual rehashing from ID Cache, and changed it
1348 to use the SILC Hash Table's auto rehash feature. Affected
1349 file is lib/silccore/silcidcache.c.
1351 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1353 * Fixed a bug in the silc_client_nickname_format function that
1354 handles the multiple same nickname formatting. Two clients
1355 with same nickname caused problems after the first one left
1356 and rejoined. It didn't format the nickname correctly.
1357 Affected file is lib/silcclient/idlist.c.
1359 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Don't change the topic if olod topic is same as new one.
1362 Affected file is silcd/packet_receive.c.
1364 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1366 * Added cross-reference support to the SILC Documentation
1367 generator. All types across all HTML files are now cross-
1368 referenced. Affected files util/robodoc/generator.c and
1369 scripts/silcdoc/silcdoc.
1371 * Added file lib/silcutil/silctypes.h to include all the
1372 arithmetic type definitions and some macros. Removed
1373 includes/bitmove.h and moved macros to silctypes.h.
1375 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1377 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1379 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1381 * Added `type' argument to silc_id_payload_parse_id function which
1382 now returns the type of the ID to the sent pointer. Affected
1383 file is lib/silccore/silcid.[ch].
1385 * Added check for CMODE_CHANGE notify type that mode change is
1386 allowed by the sender. Affected file silcd/packet_receive.c.
1388 * Added check for CUMODE_CHANGE notify type that mode change is
1389 allowed by the sender. Affected file silcd/packet_receive.c.
1390 Added the ID type as CUMODE_CHANGE notify type as argument
1391 to the `notify' client operation. Affected files are
1392 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1394 * Added function silc_client_add_server to the client library.
1395 Added support for resolving also channel and server info when
1396 received unknown entity in notify packet. Affected files are
1397 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1399 * Added function silc_command_get_status to return the command
1400 status from the command reply's argument payload. Affected files
1401 are lib/silccore/silccommand.[ch].
1403 * Added check for KICKED notify type that the kicking is
1404 allowed by the client. Affected file silcd/packet_receive.c.
1406 * Created function silc_get_input which can be used to get input
1407 (echo on or off) from user on command line. Affected files are
1408 lib/silcutil/silcutil.[ch].
1410 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1412 * Optimized silc_server_packet_relay_to_channel function.
1413 Added new function silc_channel_message_payload_encrypt which
1414 can be called directly if channel message payload needs to
1415 be encrypted and is already encoded (no need to call _encode
1416 function). Packet relaying is now done by router without any
1417 extra memory allocations. Affected files are
1418 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1419 silcd/packet_send.c.
1421 * Fixed the INVITE notify handling. It took wrong arguments
1422 as invite list and invite delete. Affected file is
1423 silcd/packet_receive.c.
1425 * Added check for TOPIC_SET notify type that the topic change is
1426 allowed by the client. Affected file silcd/packet_receive.c.
1428 * Added check for INVITE notify type that inviting is allowed by
1429 the client. Affected file silcd/packet_receive.c.
1431 * Changed the silc_server_client_on_channel to return the
1432 SilcChannelClientEntry as well. Moved the function
1433 silc_server_check_cmode_rights to server_util.[ch].
1434 Affected files are silcd/server_util.[ch], silcd/command.c.
1436 * Added function silc_server_check_umode_rights to check whether
1437 changing client's user mode is allowed. Added check for
1438 UMODE_CHANGE notify type that the umode change is allowed
1439 by the client. Affected files are silcd/server_util.[ch],
1440 silcd/packet_receive.c and silcd/command.c.
1442 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1445 ID length. It ignored that ID can be IPv6 based as well.
1446 Affected file lib/silccore/silcpacket.h.
1448 * Fixed the silc_id_id2str and silc_id_str2id to take the
1449 IPv6 address offset's into consideration. Affecte file is
1450 lib/silccore/silcid.c.
1452 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1454 * Fixed the internal Unix scheduler functions to check for
1455 NULL context they may receive. The affected file is
1456 lib/silcutil/unix/silcunixschedule.c.
1458 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1460 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1461 can specify different directory with --home command line
1462 parameter. Affected files irssi/src/silc/core/client_ops.c,
1465 * SILC-specific commands aren't now executed if the active server
1466 isn't of SILC-type, so there won't be problems with having
1467 IRC and SILC protocol support in same client. Affected files
1468 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1471 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1473 * Improved the signal support in SILC Schedule. Added new
1474 function silc_schedule_signal_call which is used by application
1475 to mark a signal to be called. It is now safe to perform
1476 any kind of tasks in signal callbacks since it is guaranteed
1477 that the application specified signal callback is called
1478 after the signal is over. Affected files are
1479 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1481 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1483 * Added `name' field to SilcChannelPrivateKey to represent
1484 application given name for the key. Moved also the context from
1485 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1486 Added the `name' argument also to the function
1487 silc_client_add_channel_private_key.
1489 Added function silc_client_current_channel_private_key to set the
1490 current channel private key in use.
1492 Added "change" command to KEY command which can be used to change
1493 the current channel private key. Bound the command also to
1494 alt+K (Alt+Shift+k).
1496 Also affected files lib/silcclient/client_channel.c,
1497 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1499 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1501 * Added silc_rng_get_byte_fast function in to the
1502 lib/silccrypt/silcrng.[ch].
1504 * Changed the interface of silc_packet_assemble and the
1505 silc_packet_send_prepare. If silc_packet_assmble is now
1506 called the application does not call silc_packet_send_prepare
1507 because the library will call it automatically. These
1508 interfaces now also return a reference to the outgoing buffer
1509 which includes the assembled packet, which the application can
1510 use to encrypt the packet.
1512 Affected files are lib/silccore/silcpacket.[ch],
1513 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1514 silcd/packet_send.c, server_backup.c and packet_receive.c.
1516 * Fixed a packet sending bug on very high load, where outgoing
1517 packet queue wasn't handled correctly and packets got corrupted.
1518 Affected files are lib/silcutil/*/silc*sockconn.c,
1519 lib/silcclient/client.c and silcd/server.c.
1521 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1523 * Added macro SILC_PACKET_DATALEN which can be used during
1524 packet assembling to check whether the data to be added to
1525 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1526 len is truncated until it fits it.
1528 Added checks for maximum length of channel message payload and
1529 private message payload also.
1531 Added checks for maximum packet length in server and in
1534 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1535 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1536 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1537 lib/silcclient/client_prvmsg.c.
1539 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1541 * Added silc_server_packet_queue_purge call to the
1542 silc_server_disconnect_remote to assure that all data in the
1543 queue before disconnecting is sent to the network. Affected
1544 file silcd/server.c.
1546 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1548 * Added the deleting of server's own ID cache entry to the
1549 silc_server_free function. Free also everything else that
1550 has been allocated in silc_server_init. The affected file
1553 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1555 * Added functions silc_parse_version_string, silc_version_to_num,
1556 and silc_ske_parse_version to parse SILC protocol style version
1557 strings. Affected files lib/silcutil/silcutil.[ch] and
1558 lib/silcske/silcske.[ch].
1560 * Added new configuration params: version_protocol, version_software
1561 and version_software_vendor to specify what version the remote
1562 host must at least be to be able to connect to server. The vendor
1563 string can be regex matched too. Added new function
1564 silc_server_connection_allowed to check maximum number of allowed
1565 connections, and allowed versions for incoming connections.
1566 Affected files are silcd/server.c, server_util.[ch] and
1569 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1571 * Added preliminary support for signals in scheduler. The
1572 signals we care about are now blocked always when the scheduler
1573 is locked. This way we can synchronise the use of signal with
1574 scheduler. It is guaranteed that when signal occurs the scheduler
1575 is not locked, and thus new tasks can be safely added to the
1578 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1579 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1580 Added new platform specific routines
1581 silc_schedule_internal_signals_[un]block and
1582 silc_schedule_internal_signal_[un]register.
1584 Added new functions to SILC Schedule API:
1585 silc_schedule_signal_[un]register. Each signal that application
1586 is going to use should be registered to the scheduler.
1588 Affected files are lib/silcutil/silcschedule.[ch],
1589 lib/silcutil/*/silc*schedule.c.
1591 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1593 * Check for unauthenticated client and server in the
1594 silc_server_new_client and silc_server_new_server functions.
1595 Affected file silcd/packet_receive.c.

1598 string is 7-bit ASCII string. Affected files are
1599 lib/silcutil/silcutil.[ch].
1601 * Added function silc_id_is_valid_server_id into the
1602 silcd/serverid.c and added checking for valid Server ID's in
1603 silc_server_new_server. The Server ID must always be based
1604 on the server's public IP address.
1606 * Added logging of DISCONNECT packet message in the server.
1607 Affected file silcd/server.c.
1609 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Changed all library interfaces that use Global RNG to also
1612 accept SilcRng as argument. Affected files are
1613 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1614 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,

1616 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1617 lib/silccrypt/rsa.c.
1619 * Added function silc_pkcs_generate_key to the
1620 lib/silccrypt/silcpkcs.[ch] for applications so that they
1621 don't need to do pkcs->pkcs->init calls anymore.
1623 * Remove SilcSocketConnection from the SFTP API since it really
1624 wasn't needed there. The application has the information
1625 saved in its contexts anyway and the SFTP layer doesn't need
1626 know about it. Affected files lib/silcsft/silcsftp.h and
1627 lib/silcsftp/sftp_[server/client].c.
1629 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1633 lib/silcutil/silcutil.c.
1635 * On EPOC the global crypto module lists are not used at all
1636 in the crypto library. Added support for using the constant
1637 algorithm list on EPOC. Affected files are
1638 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1641 * Fixed the handling of third parameter of KICKED notify, since
1642 it was mistakenly updated to SILC Protocol 1.0 even though it
1643 is to be included in 1.1. Since it is not in 1.0 it is not
1644 mandatory, and this fix now handles it only if it is provided,
1645 and it is not error if it is not provided. Affected file
1646 lib/silcclient/client_notify.c.
1648 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1655 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1657 * Check for valid socket connection in client entries before
1658 sending any messages. Fixes a crash, but doesn't fix some
1659 other underlaying bug that is lurking there. Affected
1660 file silcd/packet_send.c.
1662 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1664 * $usermode, $cumode and $cumode_space expandos shouldn't do
1665 anything with non-SILC server records. Affected file
1666 irssi/src/silc/core/silc-expandos.c
1668 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed the silc_net_check_[host/local]_by_sock to support
1671 IPv6 bound sockets as well. Now they can return IPv6 addresses
1672 as well. Affected file lib/silcutil/silcnet.c.
1674 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1675 Affected lib/silcutil/unix/silcunixnet.c.
1677 * Fixed ID rendering (at least on some platforms, not NetBSD)
1678 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1680 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1682 * Added silc_hash_public_key and silc_hash_public_key_compare
1683 functions to be used with SilcHashTable. They can be used to
1684 hash public keys and compare public keys in hash table. Affected
1685 file lib/silcutil/silcutil.[ch].
1687 * Added support for specifying multiple public keys for Client
1688 connection section in server configuration file. This makes it
1689 possible to accept multiple public keys from same host, or to
1690 make a section that accepts any incoming host, and have the
1691 accepted public keys listed in the section.
1693 Added functions silc_sever_[find/get]_public_key, added the
1694 support for this actually to all connection sections but only
1695 the Client section is currently allowed to specify multiple
1698 Affected files are silcd/server.c, server_internal.h,
1699 command.c, protocol.c, server_util.[ch], packet_receive.c.

1711 Also fixed some documentation typos.
1713 Affected files are lib/silcutil/silclog.[ch].
1715 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1717 * Fixed the server to check correctly the amount of connections
1718 from single host, by checking also the type of the connection.
1719 Fixed also the comparison of number of connections and number
1720 of allowed connections. Affected files are silcd/server.c,
1723 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1725 * Fixed the USERS command reply to save the user's mode on the
1726 channel as well. Fixed JOIN command reply to check whether a
1727 client is on channel already and not join it twice. Affected
1728 file lib/silcclient/command_reply.c.
1730 * Added new file silc-expandos.c into irssi/silc/core/ to return
1731 various stuff for various signal for the statusbar etc. updating.
1732 Now Irssi SILC client prints channel user modes etc. on the
1735 * The user mode (like server/router operator changes) is now shown
1736 on the Irssi SILC client's statusbar. The affected files are
1737 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1739 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1741 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c

1776 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1777 to avoid collisions with other libraries using same type names
1780 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1782 * Added `prefer_ipv6' argument to the functions
1783 silc_net_gethostbyname[_async]. If it is TRUE it will return
1784 IPv6 address over IPv4. If FALSE IPv4 address is returned
1785 even if IPv6 address was found. Affected files
1786 lib/silcutil/silcnet.[ch].
1788 * Added support silc_net_create_connection[_async] to fallback
1789 to IPv4 address if IPv6 address could not be used (like if

1799 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1801 * Added automatic extern "C" { ... } for C++ compilers so the
1802 application does not need to define them. Affected file
1803 includes/silcincludes.h.
1805 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1806 old name went against naming convention. Applications now
1807 include "silcclient.h" instead of "clientlibincludes.h".
1808 Removed includes/clientlibincludes.h, it is redundant now.
1810 * Renamed includes/version.h to silcversion.h.
1812 * Added really preliminary support for OS/2 into the util
1813 library. Only thread & mutex API is implemented, others
1814 are still to be implemented. Created the lib/silcutil/os2/
1815 directory. Created also file includes/silcos2.h.
1817 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1848 * Added `user_count' to the SilcChannelEntry which now tells the
1849 number of users on the channel. The user count is now saved
1850 in normal server of global channels as well. Affected files
1851 silcd/server.c, idlist.h, packet_receive.c and command.c.
1853 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1854 include file utility functions.
1856 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1857 instead of calling directly OS routines.
1859 * Fixed NICK change printing in Irssi SILC Client. Fixed
1860 KICKED notify printing in Irssi SILC Client. Affected file
1861 irssi/src/silc/core/client_ops.c.

1867 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1869 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1870 the SKE interface a bit.
1872 * Fixed padding problem in PKCS#1. The padding was not actually
1873 random since the random number generator was used incorrectly.
1874 This security bug affects only when encrypting with PKCS#1, and
1875 it is not currently used at all in SILC. SILC only use signing
1876 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1878 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1890 key_exchange_timeout, conn_auth_timeout, connections_max,
1893 Implemented all the new config settings handling in the server.
1895 Optimized the use of SKE Mutual flag usage. Use it only
1896 if connection authentication protocol is not based in public
1899 Renamed all SilcServerConfigSection* to SilcServerConfig*
1900 to have a bit shorter names.
1902 Affected files silcd/serverconfig.[ch], server.[ch], and

1936 is now done in silc_core_init() which also fixes autoconnecting
1939 Affected files irssi/src/silc/core/silc-core.c,
1940 irssi/src/fe-text/silc.c.
1942 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1944 * Added new configuration options and blocks:
1945 keepalive_secs, reconnect_count, reconnect_interval,
1946 reconnect_interval_max, reconnect_keep_trying and

1957 algorithm parts and created new file silcalgs.conf, that
1958 is now included from the example_silcd.conf.in.
1960 * Optimized the silc_server_connect_to_router_second to take
1961 the connection configuration object from the SilcServerConnection
1962 object instead of finding it during the connecting phase.
1963 Added the configuration object to SilcServerConnection struct.
1964 Affected files silcd/server_internal.h, server.c.
1966 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1968 * Add the client on channel after it was resolved at the
1969 channel message receiving, and it was not already on the
1970 channel. Affected file lib/silcclient/client_channel.c.
1972 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1988 authentication to be set at the same time.
1990 Added `prefer_passphrase_auth' setting in config file which
1991 can be used to set to prefer passwd auth if both passwd and
1992 public key is set. If not set, public key is preferred.
1993 This has effect only when being initiator (responder will try
1996 Added support for authentication with passphrase and public key
1997 at the same time. The passphrase is tried first always since
1998 it is faster to check.
2000 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2002 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2048 * Fixed the file transfer's key agreement payload to include
2049 zero port also if the hostname is NULL because it could not
2052 Call file transfer monitor callback now also if error occurs
2053 during key agreement protocol.
2055 Changed the silc_client_file_send interface to return the
2056 SilcClientFileError instead of session id. The session ID
2057 is returned into pointer provided as argument.

2095 * Fixed a bug in hash table internal routine for traversing
2096 the table with foreach callback. The current entry may
2097 become invalid in the callback but it was referenced after
2098 the callback returned.
2100 Do not allow auto rehashing of hash table during the
2101 silc_hash_table_foreach operation, for same reasons as it is
2102 not allowed for SilcHashTableList. Affected files are
2103 lib/silcutil/silchashtable.[ch].
2105 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2107 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2108 Win32 DLL. extern's in header files are now declared with
2111 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2113 * Fixed private message handling. It used some old code that
2114 caused the client to crash. Affecte file is
2115 lib/silcclient/client_prvmsg.c.
2117 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2119 * Added function silc_client_add_channel,
2120 silc_client_replace_channel_id, and removed functions
2121 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2122 from client library.
2124 * Added cross reference of the joined channels to the
2125 SilcClientEntry, and changed the SilcChannelEntry's
2126 users list to SilcHashTable. The affected files are
2127 lib/silcclient/idlist.[ch].
2129 * Fixed a bug in hash table tarversing. While the hash table
2130 is traversed with SilcHashTableList the table must not be
2131 rehashed. It is now guaranteed that auto rehashable tables
2132 are not rehashed while tarversing the list. Also defined that
2133 silc_hash_table_rehash must not be called while tarversing
2134 the table. Added function silc_hash_table_list_reset that must
2135 be called after the tarversing is over. The affected files are
2136 lib/silcutil/silchashtable.[ch].
2138 * Changed all hash table traversing to call the new
2139 silc_hash_table_list_reset in server and in client library.
2141 * Added function silc_client_on_channel to return the
2142 SilcChannelUser entry if the specified client entry is joined
2143 on the specified channel. This is exported to application as
2144 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2146 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2148 * Fixed founder regaining problem with JOIN command on normal
2149 server. The notify for mode change must be sent always and
2150 not only if !cmd->pending. Affected file silcd/command.c.
2152 * Fixed the WHOWAS command's reply sending to support the
2153 lists correctly. Affected file silcd/command.c.
2155 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2157 * When sending JOIN command to router for processing the
2158 sender's old command identifier was not saved back to the
2159 sender's command context, fixed now. The affected file is
2162 * Create the key in JOIN command of the router did not return
2163 the channel key, added check for this. Affected file is
2166 * Fixed a channel ID update bug in JOIN command reply. Do
2167 not directly upgrade the ID but call the function
2168 silc_idlist_replace_channel_id if the ID was changed.
2169 Affected file silcd/command_reply.c.
2171 * Fixed memory leaks from command calling if it would fail.
2172 Affected file silcd/command.c.
2174 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2176 * Applied patches from cras:
2178 Memory leak fixes around libaries, irssi window resize fix,
2179 new silclist.h and silcdlist.h, all extern inline changed to
2182 * Removed dotconf from lib/dotconf, not needed anymore.
2184 * Removed TRQ from lib/trq, not needed anymore.
2186 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2187 with server connections. Later this will be configurable
2188 in config file after new config file is done. Affected file
2191 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2193 * Fixed a crash in server related to channel announcements.
2194 Affected file silcd/server.c.
2196 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2198 * Fixed memory leaks in silc_server_create_new_channel*
2199 functions. Affected file silcd/server.c.
2201 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2202 which ID was changed. This way the router will send the
2203 user list for the channel again, and server won't be in
2204 desync in some rare circumstances. Affected file is
2205 silcd/packet_receive.c.
2207 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2209 * Check for NULL socket pointer in the function
2210 silc_server_packet_send_to_channel_real. Affected file
2211 silcd/packet_send.c.
2213 * Fixed the BAN notify handling to correctly remove ban
2214 list. Affected file silcd/packet_receive.c.
2216 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2218 * Fixed some header addition to Toolkit distribution in
2219 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2221 * Added lib/silcclient/client_ops_example.h as an template
2222 file for application programmers to quickly start using
2223 the SilcClientOperation functions in their application.
2224 Updated the lib/silcclient/README as well to tell about this
2225 nice file made available.
2227 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2229 * Call silc_server_remove_from_channels when removing client
2230 entry when NO_SUCH_CLIENT_ID was received. Affected file
2231 is silcd/command_reply.c.
2233 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2235 * Added server & router operator statistics updating. Affected
2236 file silcd/packet_receive.c and silcd/command.c.
2238 * Fixed the SERVER_SIGNOFF notify handling on normal server
2239 not to save the history information for clients. Same was
2240 fixed earlier in remove_clients_by_server function, but not
2241 here. Affected file silcd/packet_receive.c.
2243 * Raised the default connection-retry count from 4 to 7 in
2244 server. Affected file silcd/server.h.
2246 * Cancel any possible reconnect timeouts when we start the
2247 key exchange. Affected file silcd/server.c.
2249 * Do not reconnect on connection failure when SCONNECT was
2250 given. Affected files silcd/server.[ch].
2252 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2254 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2256 * Fixed the NICK command to always give the unformatted
2257 nickname to the one giving the NICK command. If unformatted
2258 nickname is cached already it will be formatted and the
2259 local entry will always get the unformatted nickname.
2260 Affected file lib/silcclient/idlist.c.
2262 * Fixed some double frees from client library commands.
2263 Affected file is lib/silcclient/command.c.
2265 * Fixed CUMODE command in server to assure that no one can
2266 change founder's mode than the founder itself, there was a
2267 little bug. Affected file silcd/command.c.
2269 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2271 * Removed the SilcClientCommandDestructor from the client
2272 libary, it is not needed anymore. Affected files are
2273 lib/silcclient/silcapi.h, command[_reply].[ch],
2274 client_notify, idlist.c.
2276 * Fixed GETKEY command to first resolve client, and then
2277 resolve the server only if the client was not found, instead
2278 of resolving both at the same time. Affected file is
2279 lib/silcclient/command.c.
2281 * Added silc_client_start_key_exchange_cb and lookup the
2282 remote hostname and IP address before starting the key
2283 exchange with server. The affected file is
2284 lib/silcclient/client.c.
2286 * The server's public key is now saved using the IP address
2287 of the server and not the servername for the filename.
2288 The hostname public key filename is checked as an fall back
2289 method if the IP address based filename is not found.
2291 Fixed the GETKEY command to save the fetched server key
2292 in correct filename.
2294 Print the remote server's hostname now when new key is
2295 received during connection process. Affected file is
2296 irssi/src/silc/core/client_ops.c.
2298 * Return always our own public key to the client if it asks
2299 for it with GETKEY command. Affected file silcd/command.c.
2301 * Removed the use_auto_addr variable from default config
2302 file since it was in wrong section. Affected file is
2305 * Fixed TOPIC_CHANGE notification to not route it when it
2306 was sent using silc_server_send_notify_to_channel function.
2307 Affected file silcd/command.c.
2309 * Fixed silc_server_send_notify_kicked to send the kicker's
2310 Client ID also, it was missing. Affected files are
2311 silcd/command.c, silcd/packet_send.[ch].
2313 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2315 * Do not save client history information in SERVER_SIGNOFF.
2316 Fixes the bug in normal server that it does not detect
2317 the client becoming valid after the server becomes back
2318 online. Affected file silcd/server_util.c.
2320 * Added `sock_error' field into the SilcSocketConnection
2321 context. When error occurs during socket operation (read
2322 or write) the error is saved. Added also new function
2323 silc_socket_get_error to return human readable socket error
2324 message. Affected files are lib/silcutil/silcsockconn.[ch],
2325 lib/silcutil/unix/silcunixsockconn.c, and
2326 lib/silcutil/win32/silcwin32sockconn.c.
2328 * The server now prints the socket error message in the
2329 signoff for client. Affected file silcd/server.c.
2331 * Fixed the `created' channel information sending from router
2332 to server in JOIN command. Checks now whether the channel
2333 really was created or not and set it according that.
2335 Fixed the JOIN command to use the client entry's current
2336 ID during the joining procedure instead of the one it sent
2337 in the command (it is checked though), since it can change
2338 between the packet processing and command processing, and
2339 would just case unnecessary pain in the client end. Affected
2340 file silcd/command.c.
2342 * Fixed a channel key payload sending to use correct channel
2343 ID when the server was forced to change the channel's ID by
2344 router. Router sent the key payload with the old Channel ID.
2345 Affected file silcd/packet_receive.c.
2347 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2349 * Call silc_server_save_channel_key only if the key payload
2350 was provided in the JOIN command's command reply. Affected
2351 file silcd/command_reply.c.
2353 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2355 * Fixed silc_mp_sizeinbase to return the value correctly with
2356 MPI. Affected file lib/silcmath/mp_mpi.c.
2358 * Fixed the stop_server signal to correctly stop the scheduler
2359 and gracefully stop the server when SIGTERM or SIGINT signals
2360 are received. Affected file silcd/silcd.c.
2362 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2364 * Simple handling of TERM and HUP signals. Also added some log
2365 flushing call around. Affected file is
2368 * Fixed small bugs in silclog.c. Now buffering output will take
2369 effect after 10 seconds since startup: This will ensure that
2370 no important startup messages are lost. Also output redirection
2371 will preserve original format ([Date] [Type] message).
2372 Affected file is lib/silcutil/silclog.c.
2374 * Added two options to the config file, in the logging section:
2375 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2376 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2378 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2380 * Do not print the warning about log files not being initialized
2381 more than once to avoid excess logging. Affected file is
2382 lib/silcutil/silclog.c.
2384 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2385 the SIM copying in make install in Makefile.am.pre.
2387 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2389 * Rewritten silclog APIs. Globally interesting changes follows:
2390 silc_log_set_files() changed to silc_log_set_file().
2391 silc_log_set_callbacks() changed to silc_log_set_callback().
2392 ROBOdoc documented silclog header file.
2393 SilcLogCb now returns bool to wether inihibit the default
2394 handler or not (to keep the old behaviour return always TRUE).
2395 The new APIs should also fix the problem of the
2396 silcd_error.log file that was written in the current directory.
2399 Log files streams will remain opened after silc_log_set_file()
2400 call, means less CPU usage notably on high traffic servers.
2401 File streams are now full buffered, and flushed to the disk
2402 every 5 minutes, lesses HD activity and CPU usage.
2403 Messages can be redirected, allowing admins to configure
2404 one single logfile for all server messages.
2405 the silc_log_quick global variable to activate fast-logging.
2406 Affected files lib/silcutil/silclog.[ch]
2408 * Changed some code to conform new silclog APIs. Affected
2409 files are doc/example_silcd.conf.in, silcd/server.c
2410 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2413 * Fixed a memory leak that could occur in some situations.
2414 Affected file silcd/serverconfig.c.
2416 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2418 * Added the silc_client_del_client to remove the client from
2419 all channels as well. Affected file lib/silcclient/idlist.c.
2421 * Fixed the client library to correctly remove the client
2422 from all channels when the client entry is being destroyed.
2423 Affected file lib/silcclient/client_notify.c, command.c.
2425 * Added auto-nicking support to the client library. If the
2426 applicatio now sets client->nickname it will be sent to the
2427 server after connecting by the library. This way for example
2428 SILCNICK (or IRCNICK) environment variables will have effect
2429 and always change the nickname automatically to whatever
2430 it is wanted. Affected file lib/silcclient/client.[ch].
2432 * Renamed silc_server_command_bad_chars to the
2433 silc_server_name_bad_chars and moved it to the
2434 silcd/server_util.[ch]. Added also new function
2435 silc_server_name_modify_bad to return nickname that
2436 includes bad characters as new nickname without those
2437 bad characters. This check and modify is now used in
2438 silc_server_new_client when the username is initially set
2439 as nickname, so it must be checked to be valid nickname.
2440 Affected file silcd/packet_receive.c.
2442 * The nickname length is now taken from the packet for real
2443 and not trusted to strlen() since it clearly can return
2444 wrong length for nickname including bad characters. This
2445 also applies to channel names. Affected file silcd/command.c.
2447 * Removed the lib/silcsilm/modules directory. Modules are now
2448 compiled into the lib/silcsim. Fixed the copying of the
2449 modules to follow symbolic links in Makefile.am.pre.
2451 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2453 * Fixed silc_string_regexify list creation. Fixes bugs with
2454 BAN and INVITE commands in server. The affected file is
2455 lib/silcutil/unix/silcunixutil.c.
2457 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Removed the command destructor entirely from the server's
2460 command and command reply routines. It is not needed, and
2461 its usage was buggy and caused crashes. Affected files are
2462 silcd/command[_reply].[ch].
2464 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Cancel protocol and NULL sock->protocol if timeout
2467 occurred during protocol. Affected file silcd/server.c.
2469 * Cancel protocol timeouts always before calling the final
2470 callback, to assure that after final callback is called
2471 no other state will be called for the protocol anymore.
2472 Affected file silcd/protocol.c.
2474 * Print error log if incoming connection configuration could
2475 not be found. Affected file silcd/server.c.
2477 * Fixed JOIN command to correctly save the founder mode
2478 to the client on normal SILC server, when the channel
2479 was created by the router. Affected file silcd/command.c.
2481 * Fixed LIST command (hopefully) to send correct reply
2482 packets. Affected file silcd/command.c.
2484 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * The silc_packet_receive_process now returns FALSE if the
2487 read data was invalid packet, and TRUE if it was ok.
2489 The server now checks that if unauthenticated connection
2490 sends data and its processing fails the server will close
2491 the connection since it could be a malicious flooder.
2493 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2495 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Make sure the warning about error opening a log file is
2498 printed only once and not everytime it fails (produces
2499 too much useless log). Affected file lib/silcutil/silclog.c.
2501 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2503 * Made the silc_server_daemonise() function more readable.
2504 Affected file silcd/server.c.
2506 * Pid file is now optional, the user may comment it out from
2507 the config file. Removed define SILC_SERVER_PID_FILE, we
2508 don't need a default any longer. Affected file
2509 configure.in.pre, lib/Makefile.am.pre.
2511 * Make some use of the pid file. The server now dies at startup
2512 if it detects a valid pid file on his path. The server would
2513 die anyway in this circumstance, because of the bind() failure.
2514 Affected file silcd/silcd.c.
2516 * No longer compiling lib/dotconf.
2518 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Fixed JOIN command parsing not to crash. Affected file
2521 lib/silcclient/command.c.
2523 * Fied the NICK_CHANGE notify to add the new client entry
2524 even it is resolved. This removes an <[unknown]> nick
2525 thingy bug in the client. Affected file is
2526 lib/silcclient/client_notify.c.
2528 * Do not try to allocate 0 bytes (efence does not like it)
2529 in lib/silccore/silccomand.c when encoding payload.
2531 * Do not take IRCNICK as nickname in Irssi SILC client since
2532 it is not possible to set nickname before hand connecting
2533 the server (TODO has an entry about adding auto-nicking
2536 * Changed the silc_server_command_pending to check whether
2537 there already exists an pending entry with the specified
2538 command, command identifier and pending callback. This is
2539 to fix IDENTIFY and WHOIS related crashes that may register
2540 multiple pending commands with same identifier. Affected
2541 file silcd/command.c.
2543 * Fixed the server to reconnect to the router even if it
2544 was already reconnecting and EOF was received. This to
2545 fix a possibility that the server wouldn't ever try to
2546 auto-reconnect to the router. Affected file silcd/server.c.
2548 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Fixed the server's password authentication to use the
2551 length of the locally saved password, and not the one
2552 sent in the packet. Affected file silcd/protocol.c.
2554 * Fixed same password authentication problem in the
2555 Authentication Payload handling routines in
2556 lib/silccore/silcauth.c.
2558 * Yet another password authentication problem fixed with
2559 channel password handling in silcd/command.c.
2561 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * If first character of string in silc_parse_userfqdn is '@'
2564 then do not parse it. Affected file is
2565 lib/silcutil/silcutil.c.
2567 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Fixed minor bug in IDENTIFY command reply sending, which
2570 caused various weird problems during JOIN when it was
2571 resolving names for users. Affected file silcd/command.c.
2573 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Fixed the IDENTIFY command reply sending to chech better valid
2576 clients. It was possible to send incomplete list of replies.
2577 Affected file silcd/command.c.
2579 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added silc_client_command[s]_[un]register functions now to
2582 dynamically register the commands in client library. Removed
2583 the static table of commands. This allows the client library
2584 to call commands without causing the application to know about
2585 what commands library has called.
2587 Removed the INFO command reply kludge to detect when the command
2588 was called by library. Now library use its own command reply
2589 function for INFO command.
2591 Added function silc_client_command_call to call a command.
2592 Application can use it to call command, not access the structure
2595 Now all commands that are sent by the client library (not
2596 explicitly sent by application) use own command reply functions.
2598 Affected files around lib/silcclient/ and in
2599 irssi/src/silc/core/.
2601 * Fixed the WHOIS command reply sending to chech better valid
2602 clients. It was possible to send incomplete list of replies.
2604 Fixed the WHOIS and IDENTIFY to send the request to router
2605 if normal server did not do it and did not find any results.
2607 Affected file silcd/command.c.
2609 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Moved the internal data from SilcClient context into its
2612 own file, not accesible to application. Affected files
2613 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2614 and other files in client library.
2616 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Added doc/examples installation target in Makefile.am.pre.
2621 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2624 commands the found client entry will be removed from the
2625 cache, after notifying application about the error. Affected
2626 file lib/silcclient/command_reply.c.
2628 * Changed the /MSG to check for exact nickname user gave, and
2629 not let `nick' match `nick@host' if it is only one found. Now,
2630 user must type the exact nickname (like nick@host2) even if
2631 there are no more than one same nicks found. This is to avoid
2632 a possibility of sending nickname to wrong nickname since
2633 `nick' could match `nick@host'. Affected file is
2634 irssi/src/core/silc-servers.c.
2636 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Do not print "you are now server operator" or similar when
2639 giving /away command. Affected files are
2640 irssi/src/silc/core/client_ops.c, silc-servers.h.
2642 * Made the silc_server_command_pending_error_check to send
2643 the same command reply payload it received back to the
2644 original sender of the command. This way all arguments
2645 that was received by the server will be received by the
2646 client too. Affected file silcd/command.c.
2648 * Added the silc_idcache_add to return the created cache entry
2649 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2651 * Add global clients to expire if they are not on any channel.
2652 This is because normal server will never know if they signoff
2653 if they are not on any channel. The cache expiry will take
2654 case of these entries. This is done by normal servers only.
2655 The affected files are silcd/command_reply.c,
2656 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2658 * If server receives invalid ID notification for WHOIS or
2659 IDENTIFY and the ID exists in the lists, it is removed.
2660 Affected file silcd/command_reply.c.
2662 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2663 in client then client entry that it matches is searched and
2664 the nickname is printed on the screen for user. Affected
2665 file irssi/src/silc/core/client_ops.c.
2667 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Use cache entry expire time in the LIST command reply to
2670 purge old entries from the cache after the LIST command
2671 reply has been received. This way we don't have non-existent
2672 entries in the cache for too long. Affected file is
2673 silcd/command_reply.c.
2675 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * If we are normal server, and we've not resolved client info
2678 in WHOIS or IDENTIFY from router, and it is global client,
2679 we'll check whether it is on some channel. If it is not
2680 then we cannot be sure about its validity and will resolve it
2681 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2682 file silcd/command.c.
2684 * Search channel by name (if possible) rather than by ID
2685 in IDENTIFY command's command reply. Affected file is
2686 silcd/command_reply.c.
2688 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2691 Updated specs and implemented it. Affected file silcd/command.c,
2692 silcd/packet_send.c and silcd/packet_receive.c.
2694 * Implemented the <founder auth> payload handling in the JOIN
2695 command. If provided all conditions for channel joining
2696 except requirement to provide correct passphrase can be
2697 overrided by the channel founder. Updated the protocol specs.
2698 Affected file silcd/command.c.
2700 Added support for founder auth in JOIN command in client
2701 library. Fixed the parsing of the JOIN command now to support
2702 all options as they should be. The affected file is
2703 lib/silcclient/command.c.
2705 * Optimized the WHOIS and IDENTIFY commands to send the request
2706 to router only if it includes nicknames or other names. If
2707 they include only IDs then check the local cache first before
2708 routing. Affected file is silcd/command.c.
2710 * Added channels topic announcements. Affected file is
2711 silcd/packet_receive.c and silcd/server.c.
2713 * Fixed the silc_server_send_notify_topic_set to really destine
2714 the packet to channel. Affected file silcd/packet_send.c.
2716 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2717 library. Affected file lib/silcclient/client_notify.c.
2719 * Added UMODE announcements. Affected file silcd/server.c.
2721 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Memory leak fixes in:
2725 lib/silcutil/silcsockconn.c
2726 lib/silcske/silcske.c
2727 lib/silcske/groups.c
2729 lib/silccrypt/silcpkcs.c
2730 lib/silccore/silccommand.c
2731 lib/silccore/silcidcache.c
2736 * ROBOdoc documented the lib/silcske/groups.h file and a
2737 bit changed the interface for better.
2739 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2741 * Update the client entry context in the ID cache after
2742 nick change. Affected file lib/silcclient/command.c.
2743 Fixes the CUMODE command when regaining founder privileges,
2744 and a little WHOIS problem.
2746 * Fixed silc_net_gethostbyname to correctly call the
2747 inet_ntop. Affected file lib/silcutil/silcnet.c.
2749 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2751 * Added IPv6 support checking to the configure.in.pre, added
2752 also --enable-ipv6 option to override the check. Affected
2753 file configure.in.pre.
2755 * The silc_thread_create now calls the start function
2756 directly if threads support is not compiled in. Removes
2757 ugly #ifdef's from generic code. Affected files are
2758 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2760 * Added silc_net_gethostby[name/addr]_async to asynchronously
2761 resolve. Affected files are lib/silcutil/silcnet.[ch].
2763 * Added support for rendering IPv6 based server, client and
2764 channel IDs. Affected file lib/silcutil/silcutil.c.
2766 * Added support for creating IPv6 based server IDs. Affected
2767 file is silcd/serverid.c.
2769 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2771 * Added silc_net_gethostby[addr/name] into the
2772 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2773 routines. Added silc_net_is_ip[4/6]. Affected file is
2774 lib/silcutil/unix/silcunixnet.c. All routines that take
2775 address as argument now supports both IPv4 and IPv6 addresses.
2777 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2779 * Fixed LIST command reply sending in server. Affected file
2782 * Server now sends the kicker's client ID in the KICK notify
2783 to the kicked client. Affected file silcd/command.c.
2785 * The client library now parses the kickers client ID and
2786 UI displays it. Affected files lib/silcclient/client_notify.c
2787 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2789 * Made all payload parsing function prototypes consistent.
2790 They all take now const unsigned char * and uint32 pair as
2791 the payload data instead of SilcBuffer. Changes all around
2792 the source tree. Other unsigned char* -> const unsigned char*
2793 changes around the tree as well.
2795 * Optimized SFTP client and server packet sending not to
2796 allocate new buffer for each packet but to recycle the
2797 first allocated buffer. Affected files are
2798 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2800 * Optimized the SFTP client to use SilcList instead of
2801 SilcDList for requests, because it is faster. Affected file
2802 is lib/silcsftp/sftp_client.c.
2804 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2805 into lib/silccore/silcid.[ch].
2807 Renamed silcpayload.[ch] into silcargument.[ch].
2809 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * If client entry is deleted with active key agreement
2812 session, abort the session.
2814 The silc_client_abort_key_agreement now calls the completion
2815 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2817 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2820 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Don't use __restrict in older GCC's. Affected file is
2823 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2825 * silc_net_localhost now attempts to reverse lookup the
2826 IP/hostname. Affected file lib/silcutil/silcnet.c.
2828 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2829 command. It can be used to gain founder privileges at
2830 the same time when joining the channel.
2832 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2833 kicker's client ID as well. Updated protocol specs.
2835 Defined that the server must send SILC_COMMAND_IDENTIFY
2836 command reply with error status to client who sent
2837 private message with invalid client ID.
2839 Updated the protocol specification.
2841 * Added silc_server_send_command_reply to send any
2842 command reply. Affected file silcd/packet_send.[ch].
2844 * Added silc_id_payload_encode_data to encode ID payload
2845 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2847 * The server now send IDENTIFY command reply with error
2848 status if client ID in private message is invalid. Affected
2849 file silcd/packet_receive.c.
2851 * Save the server key file with server's IP address in
2852 the filename instead of hostname. The affected file is
2853 irssi/src/silc/core/client_ops.c.
2855 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2860 * Added libtool support for compiling shared objects in
2861 lib/silcsim. Affected file configure.in.pre and
2862 lib/silcsim/Makefile.am. Original patch by cras.
2864 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2866 * Pid file configuration, and server's config file fixes
2867 patch by toma. Updated CREDITS file.
2869 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Fixed silc_client_channel_message to not try to decrypt
2872 the message twice if it resolved the destination client
2873 information. This could cause of dropping one channel
2874 message. Affected file lib/silcclient/client_channel.c.
2876 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2879 lib/silcclient/client.c. This function is used when the SILC
2880 Client is run under some other scheduler, or event loop or
2881 main loop. On GUI applications, for example this may be
2882 desired to used to run the client under the GUI application's
2883 main loop. Typically the GUI application would register an
2884 idle task that calls this function multiple times in a second
2885 to quickly process the SILC specific data.
2887 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2889 * Fixed silc_server_drop() for dropping the supplementary
2890 groups as well, this could cause a security hole on some
2893 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2898 * Write PID file after dropping privileges. Added -F option
2899 to run server on foreground. A patch by debolaz.
2900 Affected files silcd/server.c, silcd/silcd.c.
2902 * Fixed MOTD to return the MOTD file server name. Affected
2903 file silcd/command.c.
2905 * Added INFO command reply handling to the Irssi SILC Client.
2906 Affected file irssi/src/silc/core/client_ops.c.
2908 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Fixed the silc_idcache_list_* routines to really support
2911 the dynamic list. Fixes a crash. Affected file is
2912 lib/silccore/silcidcache.c.
2914 * Fixed the LIST command reply to really call LIST command's
2915 pending callbacks. Affected file silcd/command_reply.c.
2917 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Update conn->local_entry->nickname after giving NICK
2920 command. Affected file lib/silcclient/command.c.
2922 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2924 * Added the [pid] option to the silcd configuration file
2926 Affected files: serverconfig.[ch] and silcd.c
2928 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * Save fingerprint in WHOIS command reply in server.
2931 Affected file silcd/command_reply.c.
2933 * Fixed NICK commands pending callback registration.
2934 Affected file lib/silcclient/command.c.
2936 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Use ++server->cmd_ident when sending commands in server,
2939 instead of random number. Affected file silcd/command.c.
2941 * Fixed GETKEY command reply to call actually GETKEY pending
2942 command callbacks. Affected file silcd/command_reply.c.
2944 * A bit stricter check for nicknames. Check for same nickname
2945 in NICK command also. Affected file silcd/command.c.
2947 * Do not call INFO command everytime client ID changes, only
2948 during first connecting. Affected file lib/silcclient/client.c.
2950 * Set the new nickname only after successful command reply for
2951 NICK command is returned by server. Affected file
2952 lib/silcclient/command.c.
2954 * Remove nicknames from nicklist during server_signoff notify.
2955 Should fix /NAMES bit more. The affected file is
2956 irssi/src/silc/core/silc-channels.c.
2958 * Added `fingerprint' field to the SilcIDListData in the
2959 silcd/idlist.h to hold the fingerprint of the client's
2962 Send the fingerprint of the client's public key in WHOIS
2965 Affected files silcd/command.c, and silcd/idlist.[ch].
2967 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2968 create fingerprint from given data.
2970 * Show the fingerprint of the client's public key in WHOIS.
2971 Affected files irssi/src/module-formats.[ch] and
2972 irssi/src/silc/core/client_ops.c.
2974 * Format the multiple same nicknames also during JOIN and
2975 NICK_CHANGE notifys. Affected file is
2976 lib/silcclient/client_notify.c.
2978 * Do not print error on screen for invalid private message
2979 payload since it can come if someone is sending private
2980 messages with wrong key. Affected file
2981 lib/silccore/silcprivate.c.
2983 * Fixed multiple concurrent /PING crash. Affected file
2984 lib/silcclient/command.c.
2986 * Changed the wrong ID encoding. All IP addresses must be
2987 in MSB first order in encoded format. They were encoded
2988 wrong and was in LSB format. Affected files are
2989 silcd/serverid.c, lib/silcutil/silcutil.c.
2991 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2993 * Call the `connect' client operation through the scheduler
2994 in case of error. Affected file lib/silcclient/client.c.
2996 * Call the `failure' client operation even if the error
2997 occurred locally during a protocol. Affected file is
2998 lib/silcclient/protocol.c.
3000 * Added support of sending LIST command to router from normal
3001 server. This way normal server can get list of all channels
3002 in the network too. Fixed the channel list sending in the
3003 server too. Affected files are silcd/command.c, and
3004 silcd/command_reply.[ch].
3006 * Added silc_server_update_channels_by_server and
3007 silc_server_remove_channels_by_server. They are used during
3008 disconnection of primary router and in backup router protocol.
3009 Affected file silcd/server_util.[ch], silcd/server.c and
3010 silcd/server_backup.c.
3012 * Fixed channel adding to global list in IDENTIFY command
3013 reply in server. Affected file silcd/command_reply.c.
3015 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * If the incoming packet type is REKEY or REKEY_DONE process
3018 that packet always synchronously. Fixes yet another MAC
3019 failed error on slow (dialup) connections. Affected file
3020 lib/silcclient/client.c and silcd/server.c.
3022 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Call check_version SKE callback for initiator too. Affected
3025 file lib/silcske/silcske.c.
3027 * Implemented fix for security hole found in the SKE that was
3028 fixed in the specification few days back; the initiator's
3029 public key is now added to the HASH value computation.
3030 Added backwards support for the old way of doing it too, for
3031 old clients and old servers. Affected file is
3032 lib/silcske/silcske.c.
3034 * Enabled mutual authentication by default in SKE. If initiator
3035 is not providing mutual authentication the responder will
3036 force it. This will provide the proof of posession of the
3037 private key for responder. The affected files are
3038 lib/silcclient/protocol.c and silcd/protocol.c.
3040 * Do not cache anymore the server's public key during SKE.
3041 We do mutual authentication so the proof of posession of
3042 private key is done, and if the server is authenticated in
3043 conn auth protocol with public key we must have the public
3044 key already. Affected file silcd/protocol.c.
3046 * Added new global debug variable: silc_debug_hexdump. If
3047 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3048 file lib/silcutil/silclog.[ch].
3050 * Fixed compilation warning due to char * -> const char *.
3051 Affected files lib/silcutil/silcnet.h, and
3052 lib/silccore/silcauth.[ch].
3054 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * Fixed CMODE command when new channel key was created. If
3057 the creation failed the old key was removed. Next time giving
3058 same command would crash the server since the old key was
3059 freed already. Affected file silcd/command.c.
3061 * Fixed the silc_server_announce_get_channels to not crash
3062 on reconnect. Affected file silcd/server.c.
3064 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Added silc_log_set_debug_string function to set a regex
3067 string to match for debug output. Only the function names,
3068 or filenames matching the given debug string is actually
3069 printed. This way it is possible to filter out those debug
3070 strings that user is not interested in.
3072 Fixed a bug in silc_string_regexify.
3074 Affected files lib/silcutil/silclog.[ch], and
3075 lib/silcutil/unix/silcunixutil.c.
3077 * Changed the -d options in both server and Irssi SILC client
3078 to take the debug string as argument. Affected files
3079 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3081 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Added silc_hash_babbleprint to create a Bubble Babble
3084 Encoded fingerprint. The encoding is developed by Antti
3085 Huima (draft-huima-babble-01.txt), and it creates human
3086 readable strings out of binary data. Affected file
3087 lib/silccrypt/silchash.[ch].
3089 * Print the babble print now in addition of fingerprint as well
3090 in Irssi SILC client. Affected files are
3091 irssi/src/fe-common/silc/module-formats.[ch],
3092 irssi/src/fe-common/silc/core/client_ops.c.
3094 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * Fixed a security problem found in SKE. The initiator's
3097 public key too is now added to the HASH hash value creation
3098 which is signed by the responder to create the SIGN value.
3099 This will prevent anyone in the middle to lie to the responder
3100 about the initiator's public key. If this is done now, the
3101 man in the middle will get caught. Updated the protocol
3104 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Better installation directory handling. Configure module
3107 paths and other paths automatically to example_silc* files
3108 in doc/. A patch by toma.
3110 * Fixed compiler warning from MPI library, and from SILC RNG.
3113 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3114 It can be configured with ./configure. A patch by toma.
3116 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Find correct make to use in prepare-clean. A patch by
3119 toma. Affected file prepare-clean.
3121 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3123 * Added irssi variables use_auto_addr, auto_bind_ip,
3124 auto_bind_port and auto_public_ip.
3126 * Changed the interface for silc_client_send_key_agreement
3127 in lib/silcclient/silcapi.h
3131 irssi/src/silc/core/silc-core.c
3133 lib/silcclient/silcapi.h
3134 irssi/src/silc/core/silc-channels.c
3135 lib/silcclient/client_keyagr.c
3138 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Added silc_pkcs_public_key_compare to compare two
3141 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3143 * Check that the client who set the founder mode on the
3144 channel is the same client that is giving the founder
3145 mode to itself. It is done by comparing the saved public
3146 key (it is saved even in the authentication is passphrase).
3147 Affected file silcd/command.c.
3149 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Do not process packet for disconnected socket connection.
3152 Affected file lib/silccore/silcpacket.c.
3154 * Process the DISCONNECT packet through scheduler in the
3155 client library. Affected file lib/silcclient/client.c.
3157 * Fixed the silc_client_packet_parse to not to increase
3158 the packet sequence number if the conn->sock and the
3159 current socket connection is not same. This can happen
3160 for example during key agreement when the conn includes
3161 multiple socket connections (listeners). Affected file
3162 lib/silcclient/client.c.
3164 * The sender of the file transfer request now provides also
3165 the pointer (listener) for the key exchange protocol. If
3166 the listener cannot be created then it sends empty key
3167 agreement and lets the receiver provide the listener.
3169 Added `local_ip' and `local_port' arguments to the
3170 silc_client_file_send. If they are provided they are used,
3171 if not then it will attempt to find local IP address, if
3172 not found or bind fails then the remote client will provide
3175 Affected files are lib/silcclient/client_ftp.c and
3176 lib/silcclient/silcapi.h.
3178 * Extended the FILE SEND command to support defining the
3179 local IP and port for key exchange listener. They are

3184 * Defined to WHOIS command reply the sending of fingerprint
3185 of the client's public key (if the proof of posession of the
3186 corresponding private key is verified by the server).
3187 Updated to the protocol specification.
3189 * Added support of receiving the client's public key's
3190 fingerprint in command reply in client library. Affected
3191 file is lib/silcclient/command_reply.c, and
3192 lib/silcclient/idlist.[ch].

3251 preserve the WHOWAS info for the client. Affected file
3252 silcd/server_util.c.
3254 * Fixed SERVER_SIGNOFF notify handling in the server. The
3255 server is now able to process incoming SERVER_SIGNOFF notify
3256 for a server that it doesn't even know about. It will remove
3257 the clients provided in the notify. Affected file
3258 silcd/packet_receive.c.
3260 * Check for partial packet in data queue after every packet that
3261 was found from the queue. Return and wait for more data if
3262 there is partial data in queue. Affected file is

3280 irssi/src/fe-common/silc/module-formats.[ch].
3282 * Wrote a help file for FILE command.
3284 * Added silc_rng_global_get_byte_fast to get not-so-secure
3285 random data as fast as possible. Random data is read from
3286 /dev/urandom if available and from the SILC RNG if not
3287 available. It is used in padding generation. Affected file
3288 lib/silccrypt/silcrng.[ch].
3290 * All packets in client library are now processed synchronously.
3291 Optimized packet processing a lot. Affected file
3292 lib/silcclient/client.c.

3303 * Assure that silc_client_notify_by_server_resolve does not
3304 resolve the client information multiple times. If it cannot
3305 be found by the first it cannot be found at all. Affected
3306 file lib/silcclient/client_notify.c.
3308 * Fixed WHOWAS command reply calling. Affected file
3309 lib/silcclient/command_reply.c.
3311 * Removed all references to silc_idlist_get_client from the
3312 Irssi SILC client since that call is internal call used by
3313 the library. The Irssi SILC client will use now client
3314 retrieval functions found in silcapi.h.
3316 * Fixed a bug in resolving nickname info before sending
3317 private message. It used freed memory. Affected file
3318 irssi/src/silc/core/silc-servers.c.

3339 * Added silc_net_localip to return local host's IP address.
3340 Affected file lib/silcutil/silcnet.[ch].
3342 * If key exchange or rekey protocol is active for a connection
3343 parse all packets syncronously since there might be packets
3344 in packet queue that we are not able to process without first
3345 processing packets before them. Affected file silcd/server,
3346 lib/silcclient/client.c.
3348 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3349 whether library should continue processing the packet.
3350 Affected file lib/silccore/silcpacket.h.

3396 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3397 is incomplete and is being resolved, it won't be resolved
3400 Make sure also that USERS command reply does not resolve
3401 twice information. Affected file is
3402 lib/silcclient/command_reply.c.
3404 Make sure that silc_client_get_clients_by_list does not
3405 resolve twice same information.
3407 * Check for valid client->id in the silc_server_free_client_data.
3408 Affected file silcd/server.c.
3410 * Fixed /GETKEY nick@server not to crash if the server entry

3423 * Call the silc_server_udpate_servers_by_server in the
3424 primary router that comes back online in the backup resuming
3425 protocol. Otherwise it routes packets wrong. Affected file
3426 silcd/server_util.[ch], silcd/server_backup.c.
3428 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3431 lib/silcutil/silcbuffmt.[ch].
3433 * Redefined the SILC packet header to include the padding
3434 length. Affected file lib/silccore/silcpacket.[ch].
3436 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3437 length for maximum padding up to 128 bytes). Affected
3438 file lib/silccore/silcpacket.h.
3440 * Removed all backwards support for old 0.5.x MAC thingies.
3441 The SILC packet header change makes it impossible to be
3442 backwards compatible.
3444 * Send the ENDING packet with timeout in the backup resuming
3445 protocol. This is to assure that all routers has connected
3446 to the primary router. Affected file silcd/server_backup.c.
3448 * Changed the RNG to take the first IV from random data. It
3449 used to take it from zero actually. Changed the RNG also
3450 to use /dev/urandom during session. /dev/random is used
3451 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3453 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3456 (the packet length) encrypted. Affected files aroung the
3457 code tree, lib/silccore/silcpacket.[ch]. Removed the
3458 SilcPacketCheckDecrypt callback. It is not needed anymore
3459 since the silc_packet_receive_process will determine now
3460 whether the packet is normal or special.
3462 * Implemented the unidirectional MAC keys. Affected files
3463 lib/silcske/silcske.c, silcd/protocol.c and
3464 lib/silcclient/protocol.c.

3471 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Allow backup router to announce servers. All servers
3474 announced by backup router are added to the global list
3475 automatically. Update hte server's socket to our primary
3476 router also when backup router announces a server.
3477 Affected file silcd/packet_receive.c.
3479 * Do not update the client->router in the function
3480 silc_server_udpate_clients_by_server if the client is on
3481 global list. We might fail to find any specific server
3482 for locally connected clients and local cell clients. They
3483 should still use the `from' and not `to' as client->router.
3484 This fixes backup router resuming protocol. Affected file
3485 silcd/server_util.c.
3487 * Decrease channel statistics count only if the channel
3488 deletion worked. Affected files are silcd/server.c and
3489 silcd/server_util.c.
3491 * Added silc_server_update_servers_by_server to update origin
3492 of all server entries. Used during backup router protocol.

3509 to the router it came from. Affected file is
3510 silcd/packet_send.c. Fixed memory leak too.
3512 * Announce informations for incoming router connection, but
3513 only after checking if it is replaced by backup router.
3514 Affected file silcd/packet_receive.c.
3516 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3519 router environment. Affected file silcd/server_backup.c.
3521 * Route packet only to one router in the function
3522 silc_server_packet_send_to_channel. Affected file is
3523 silcd/packet_send.c.
3525 * Fixed silc_server_send_notify_dest to set the broadcast
3526 flag. Fixed the silc_server_send_notify_topic to actually
3527 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3528 Affected file silcd/packet_send.c.
3530 * Changed the SFTP Filesystem interface. Changed the
3531 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3532 the filesystem operation function. The SilcSFTPFilesystem
3533 is now a context that is allocated by all filesystem allocation
3534 functions and it already includes the operations structure
3535 and filesystem specific context. It is given as argument
3536 now to the silc_sftp_server_start. This made the interface
3537 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3538 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3540 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3542 * Changed the backup router adding and getting interfaces
3543 in the server. The router that will be replaced by the
3544 specified backup router is now sent as argument. Affected

3597 send any data. Affected file lib/silcclient/client.c.
3599 * Implemented the backup router support when the primary router
3600 goes down. The servers and routers can now use the backup
3601 router as new primary router without loosing connectivity.
3603 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3606 in the server to indicate disabled entry. All data read
3607 from the connection will be ignored and no data is sent
3608 for entry that is disabled. Affected files are
3609 silcd/idlist.h, silcd/server.c.
3611 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3638 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3639 Affected file lib/silcutil/silcbuffer.h.
3641 * Changed various routines in the core library to use the new
3642 silc_buffer_set instead of allocating new buffer only for
3645 * Added 64-bit value formatting and unformatting support to the
3646 silc_buffer_[un]format routines. Affected file is
3647 lib/silcutil/silcbuffmt.[ch].

3659 * Defined the file transfer to the SILC Protocol. Added
3660 new packet type SILC_PACKET_FTP and defined File Transfer
3661 Payload. The mandatory file transfer protocol is SFTP
3662 (SSH File Transfer Protocol). Affected file in addition
3663 of the internet draft is lib/silccore/silcpacket.h.
3665 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3666 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3667 is used as part of backup router protocol when the primary
3668 router of the cell is back online and wishes to resume
3669 the position as primary router.
3671 * Redefined the MAC generation keys in the protocol. The
3672 same key is not used anymore in both direction. Both
3673 direction will now use different keys for sending and
3674 receiving. This fixes a potential security flaw. This
3675 change causes incompatibilities in the protocol.
3677 * Redefined also the MAC computation from the packet.
3678 An packet sequence number is now added to the MAC
3679 computation. This prevents possible replay attacks against
3680 the protocol. This change too causes incompatibilities
3683 Added `sequence' field to the SilcPacketContext to hold
3684 the current sequence number for the packet.
3686 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Added `created' field to the SilcIDListData in the file
3689 silcd/idlist.h to indicate the time when the entry was
3692 * Added `created' field to the SilcChannelEntry too. Affected
3693 file silcd/idlist.h.
3695 * Added `creation_time' aguments to all the announcement functions
3696 in the server. If it is provided then only the entries that
3697 was created after the provided time frame are actually
3698 announced. Affected file silcd/server.[ch].
3700 * The protocol says that the Channel ID's IP address must be
3701 based on the router's IP address. Added check for this in
3702 the silc_server_new_channel when processing incoming New Channel
3703 Payload. Affected file silcd/packet_receive.c.
3705 * Print out the correct version with --version in SILC client.
3706 Affected file irssi/src/silc/core/silc-core.c.
3708 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Fixed WHOWAS command to check for completnes of the client
3711 entry always, not just when the command is coming from client.
3712 Affected file silcd/command.c.
3714 * Added new function silc_server_packet_queue_purge to purge the
3715 outgoing data queue to the network. After the function returns
3716 it is guaranteed that the outgoing packet queue is empty.
3717 Affected file silcd/packet_send.[ch].
3719 * Purge the outgoing packet queue in the rekey protocol's final
3720 callback to assure that all rekey packets go to the network
3721 before quitting the protocol. Affected file silcd/server.c.
3723 * Added silc_client_packet_queue_parse as similar function as
3724 in server to the client library. The affected file is
3725 lib/silcclient/client.c.
3727 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3729 * Splitted silcd/server.c and created silcd/server_util.[ch]
3730 for utility functions.
3732 * Added new socket flag SILC_SF_DISABLED to indicate that the
3733 connection is open but nothing can be sent to or received from
3734 the connection. Affected file lib/silcutil/silsockconn.[ch].
3735 The checking for disabled socket is checked in the low level
3736 silc_socket_write and silc_socket_read functions.
3738 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Allow only nicknames and channel names that fits into the
3741 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3743 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * When processing JOIN command reply in server check that if
3746 the channel exists in our global list we'll move it the local
3747 list. Affected file silcd/command_reply.c.
3749 * Fixed the check whether client is joined on the channel already
3750 in JOIN command. Affected file lib/silcclient/command.c.
3752 * Fixed the JOIN command reply to check whether the channel
3753 already exists. Affected file lib/silcclient/command_reply.c.
3755 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3757 * Added silc_ske_status_string to map the SKE error numbers
3758 to readable strings. The affected files are
3759 lib/silcske/silcske[_status].[ch].
3761 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Do not show the private channels on the WHOIS channel list
3764 as it is not allowed by the protocol. The affected file is
3767 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3769 * Assure that the packet length digged from the actual packet
3770 is something sensible in the silc_packet_decrypt_rest_special
3771 in lib/silccrypt/silcpacket.c.
3773 * Free and NULL the allocated pointer in silc_hmac_alloc if
3774 the HMAC allocation fails. The affected file is
3775 lib/silccrypt/silchmac.c.
3777 * Print the selected security properties to the log files in
3778 the server. Affected file silcd/protocol.c.
3780 * Add SKE's reference counter even if calling the completion
3781 callback manually. Otherwise it goes negative, although it
3782 does not cause any problems. The affected file is
3783 lib/silcske/silcske.c.
3785 * Remove the client entry with short timeout after giving the
3786 KILL command. Affected file lib/silcclient/command.c.
3788 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3789 case all found clients are already disconnected (WHOWAS would
3790 found them) in the server. Affected file silcd/command.c.
3792 * Update the last_receive (time of last data received) to be
3793 updated only when received private or channel message so that
3794 the idle time showed in WHOIS makes more sense.
3796 * Added boolean field `valid' in to the SilcClientEntry in the
3797 client library to indicate whether the entry is valid or not.
3798 This fixes the nickname change bug on channel when changing
3799 the nickname to be same than the old (like nick to Nick) the
3800 nickname formatter doesn't set the new nick anymore to Nick@host.
3801 Affected file lib/silcclient/idlist.[ch].
3803 * Now actually fixed the nickname changing on disconnection.
3804 Added new function silc_change_nick to the Irssi SILC Client.
3805 Affected file irssi/src/silc/core/client_ops.c,
3806 irssi/src/silc/core/silc-nicklist.[ch].
3808 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Check that the public key exists in the GETKEY command before
3811 trying to encode it. Affected file silcd/command.c.
3813 * Print some notifications on received public keys with GETKEY
3814 command in the Irssi SILC Client. Affected files are
3815 irssi/src/fe-common/silc/module-formats.[ch],
3816 irssi/src/silc/core/client_ops.c.
3818 * Use IDENTIFY command to resolve the server information in the
3819 GETKEY command instead of INFO command. Affected file
3820 lib/silcclient/command.c.
3822 * All command reply functions in the client library now calls
3823 the pending command reply callbacks even if an error has
3824 occurred. The server has done this a long time and now it was
3825 time to move the client library to this as well. Now all
3826 errors can be delivered back to the pending command reply
3827 callbacks if necessary. Affected files are
3828 lib/silcclient/command[_reply].[ch].
3830 * Change the nickname on disconnection back to the username
3831 because in reconnect the server will enforce it to it anyway.
3832 Affected file irssi/src/silc/core/silc-servers.c.
3834 * Fixed a config file parsing bug in the Irssi SILC client.
3835 Affected file irssi/src/silc/core/clientconfig.c.
3837 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * When printing the channel mode on JOIN, verify that the
3840 channel key and channel's HMAC are valid. Affected file
3841 irssi/src/silc/core/client_ops.c.
3843 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3845 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3846 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3847 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3849 * Removed channel key rekey task deleting from the function
3850 silc_server_save_channel_key. Affected file silcd/server.c.
3851 Added explicit timeout task context instead that is used to
3852 delete the task if we are registering a new task before the
3853 new task has elapsed.
3855 * When channel key rekey occurs the client library now saves
3856 the old channel key for a short period of time (10 seconds) and
3857 is able to use it in case some is still sending channel
3858 messages encrypted with the old key after the rekey. Affected
3859 file lib/silcclient/[idlist.h|client_channel.c].
3861 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Added check to the silc_server_new_id_real to not accept
3864 new ID if it is the sender's own ID. Affected file is
3865 silcd/packet_receive.c.
3867 * Assure that we do not announce ourself or the one we've
3868 sending our announcements when we're router and are announcing
3869 servers to our primary router. Affected file silcd/server.c.
3871 * Fixed silc_server_command_identify_check_client to assemble
3872 correct WHOIS packet. It send corrupted WHOIS packet and
3873 caused problem with router to router connections. Affected
3874 file silcd/command.c.
3876 Fixed also silc_server_command_whois_check the same way
3877 as for the IDENTIFY command.
3879 * Added new SilcIDListStatus to the server in the SilcIDListData
3880 structure. The status now includes the current status of
3881 the entry (like registered, resolved etc.). Affected file
3882 silcd/idlist.[ch]. Defined a bunch of different status types
3883 as well. This replaced the old boolean registered field as well.
3885 Added resolve_cmd_ident field to the SilcClientEntry structure
3886 too so that if the entry is for example being resolved so
3887 another command may attach to the same pending command reply
3888 without requiring to resolve the same entry again. This concept
3889 should optimize the WHOIS and the IDENTIFY resolving under
3890 heavy load by taking away unnecessary resolving for entries
3891 that are being resolved already.
3893 Added support for adding multiple pending commands for one
3894 command idenfier. Affected file silcd/command[_reply].[ch].
3896 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3897 before deleting the data. Otherwise the hash table will have
3898 freed data in comparison functions. Affected file is
3899 silcd/command_reply.c.
3901 * Fixed silc_idlist_replace_client_id to add the new entry to
3902 the cache with NULL nickname. Otherwise there will be invalid
3903 memory as the nickname after the nickname is freed. Affected
3904 file silcd/packet_receive.c.
3906 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3907 saved into wrong slots because the previous number of entries
3908 was not taken into account. Affected file silcd/idlist.c.
3909 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3911 * If we are router and we receive JOIN notify to a channel that
3912 does not have any users then notified client is marked as the
3913 channel founder, as it is it. The affected file is
3914 silcd/packet_receive.c
3916 * Added to the extended hash table API's table_del_*ext functions
3917 the destructor as argument too, so that the caller can decide
3918 which destructor to use or whether to use destructor at all.
3919 Affected file lib/silcutil/silchashtable.[ch].
3921 * Fixed ID Cache purging. It actually deleted the entries from
3922 the hash table after the data was freed. The hash table ended
3923 up comparing freed memory. The affected file is
3924 lib/silccore/silcidcache.c.
3926 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3928 * Fixed Irssi SILC client's KILL command's HELP syntax.
3930 * The USERS command now resolves the detailed user information
3931 if the userinfo field is missing. Affected file is
3932 lib/silcclient/command_reply.c.
3934 * Do not print error in silc_file_read if the read file does
3935 not exist. Just silently return NULL. Affected file is
3936 lib/silcutil/silcutil.c.
3938 * Fixed the silc_log_output to not wine about NULL filename
3939 and to not create some bogus " " filename. Affected file is
3940 lib/silcutil/silclog.c.
3942 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3944 * Fixed various printing bugs on the user interface in the
3945 Irssi SILC Client. Minor changes that were forgotten from
3948 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Fixed the configure.in.pre and the compilation and distribution
3951 environment to support the new autoconf 2.52. That version is
3952 now required to compile the CVS trunk.
3954 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3957 to generally parse user@fqdn format strings. Affected file
3958 lib/silcutil/silcutil.c.
3960 * Added nickname_format and nickname_force_format fields to the
3961 SilcClientParams structure. The first one defines the format
3962 for the nicknames that the library will enforce if the receives
3963 multiple same nicknames. The second one is boolean value and
3964 can be used to force the library to always enforce the format
3965 to the nicknames regardles whether there are multiple nicknames
3966 or not. This configurable formatting was employed to flexibly
3967 support accessing multiple nicknames from the user interface.
3968 The userinterface can now set the nicknames to what ever format
3969 they prefer. Affected file lib/silcclient/silcapi.h.
3971 Added function silc_client_nickname_format to the file
3972 lib/silcclient/idlist.c. It performs the nickname formatting.
3974 Added new field `hostname´ to the SilcClientEntry context.
3975 It holds the hostname of the client. Affected file is
3976 lib/silcclient/idlist.h.
3978 * Irssi SILC Client sets the nicknames in nick@hostn format.
3979 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3980 irssi/src/silc/core/silc-core.c.
3982 The WHOIS printing now also shows both the real nickname and
3983 the formatted nickname so that user knows how to access the
3984 user if there are multiple same nicknames cached. Affected
3985 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3986 printing formatting too to take the hostname now as a separate
3987 argument. The Affected file is
3988 irssi/src/fe-common/silc/modules-formats.[ch].
3990 * Changed the silc_client_get_clients_local to accept the formatted
3991 nickname as argument. It accepts the real nickname too but the
3992 formatted nickname can be used to find the true entry from
3993 multiple entries. Affected file lib/silcclient/silcapi.h and
3994 lib/silcclient/idlist.c.
3996 * Added nickname_format_parse field to the SilcClientParams.
3997 It is a callback function provided by the application to parse
3998 the nickname out of the formatted nickname string. The library
3999 calls it to get the nickname from the formatted string. Since
4000 the application generally knows better the format of the nickname
4001 string it parses it instead of the library, even though library
4002 encodes the formatted string. If the callback function is not
4003 provided then the library will use the string as is. The
4004 affected file is lib/silcclient/silcapi.h.
4006 * All the nickname strings passed to the client library in
4007 commands are now expected to be formatted nickname strings.
4008 If the command does not support the formatted nickname string
4009 it will assume that the sent string is the actual nickname.
4010 Affected file lib/silcclient/command.c.
4012 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Added public key authentication support to OPER and SILCOPER
4015 commands in the client library. Affected file is
4016 lib/silcclient/command.c.
4018 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4020 * Changed the get_auth_methdod client operation to be asynchronous.
4021 It can be async if the application resolves the authentication
4022 method from the server during the negotiation. Added new
4023 SilcGetAuthMeth completion callback that the application will
4024 call after resolving the authentication method.
4026 Added function silc_client_request_authentication_method that
4027 the application can use to resolve the authentication method
4028 from the server. Added also SilcConnectionAuthRequest callback
4029 that the library will call after the server has replied. The
4030 application can call this function if it does not know the
4031 current authentication method.
4033 Affected files are lib/silcclient/client.c and
4034 lib/silcclient/silcapi.h.
4036 * The Irssi SILC client now automatically resolves the authentication
4037 method incase any configuration information is not present (and
4038 currently there never is). The affected file is
4039 irssi/src/silc/core/client_ops.c.
4041 * Fixed public key authentication from the client library.
4042 Affected file lib/silcclient/protocol.c. Changed also the
4043 protocol specification about the public key authentication in
4044 the connection authentication protocol. The actual data to be
4045 signed is now computed with a hash function before signing.
4047 * Fixed the public key authentication from the server as well.
4048 Affected file silcd/protocol.c.
4050 * Removed the mlock()'s from the memory allocation routines.
4051 Affected file lib/silcutil/silcmemory.c. The ./configure does
4052 not check anymore for the mlock(). Affected file is
4055 * Fixed USERS command in server to allow the execution of the
4056 command for private and secret channels if the client sending
4057 the command is on the channel. Affected file silcd/command.c.
4059 * Fixed silc_client_get_clients_local to return the clients
4060 count correctly. It could return wrong value. Affected file
4061 lib/silcclient/idlist.c.
4063 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4066 types. The assembler optimizations seemed not to like 64-bit
4067 data types. The assmebler optimizations thus are now enabled
4068 also for BSD systems as opposed to only enable them for Linux.
4070 * Do not check for threads at all on BSD systems. Affected
4071 file configure.in.pre.
4073 * Removed -n and -h options from the Irssi SILC Client since
4074 they are not used in silc.
4076 * Fixed the prime generation to assure that the first digit
4077 of the generated random number is not zero since our conversion
4078 routines does not like number strings that starts with zero
4079 digit. If zero digit is seen the random number is regenerated.
4080 This caused some corrupted RSA keys when the zero first digit
4081 was met. Affected file lib/silcmath/silcprimegen.c.
4083 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4085 * Fixed WIN32 configuration in the ./configure script.
4086 Fixed to include xti.h on environments that has it.
4087 Patches by Carsten Ilchmann and andrew.
4089 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Changed the silc_id_create_client_id to be collision
4092 resistant. It is now assured that there cannot be created
4093 two same client ID's. I suspect that some weird bugs in
4094 the server were actually caused by duplicate Client IDs.
4095 Affected file silcd/serverid.[ch]. A router receiving
4096 new ID now also assures and informs the sending server
4097 if the ID caused collision.
4099 * Changed the silc_id_create_channel_id to also assure that
4100 there are no collisions.
4102 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * Statement about ignoring the Mutual Authentication flag when
4105 performing rekey with PFS was a bit misleading. It is ignored
4106 if it was set in the initial negotiation, it cannot be even
4107 set in the rekey. Fixed in the ke-auth draft. Started the
4108 new versions of the protocol drafts in the doc/.
4110 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4112 * Fixed a bug in silc_client_command_identify_save when saving
4113 new channel information. The channel name was no duplicated
4114 and caused crash on exit. Affected file is
4115 lib/silcclient/command_reply.c.
4117 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Fixed the getkey command handling in the server. Send just
4120 empty OK reply to the sender if the key could not be fetched
4121 (but everything else was ok, like the key just was not available).
4122 Changed the public key parameter to optional in the protocol
4123 specs so that empty OK reply can be sent. Affected file
4126 Added a message to Irssi SILC client to tell to user if the
4127 server did not return a public key.
4129 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4131 * Fixed a channel key regeneration bug. It registered new
4132 timeout tasks exponentially until all system resources were
4133 used. Affected file silcd/server.c.
4135 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Added the SILC Document generator to the scripts/silcdoc.
4138 It can be used to generate the Toolkit Reference Manual out
4139 of the source tree. Internally it will also use the RoboDoc
4140 generator now imported in util/robodoc.
4142 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4144 * Added couple of return's in rekey protocol if error orccurred
4145 during the protocol. The execution must be terminated.
4146 Affected file silcd/protocol.c. Also, terminate the protocol
4147 always with timeout.
4149 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * The client's Client ID was created initally from the wrong
4152 nickname (it could have been in format nick@host) in the
4153 silc_server_new_client. Affected file silcd/packet_receive.c
4155 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4157 * Added some SILC_LOG_ERROR's to various error conditions
4158 if client could not be added to ID cache. Affected files
4159 silcd/packet_receive.c and silcd/server.c.
4161 * When client's sock->user_data is freed, NULL also the
4162 client->router and client->connection pointers. Added check
4163 for these pointers being NULL to various places around the
4164 code. Affected file silcd/server.c.
4166 * Added client->data.registered == TRUE checks to various
4167 places around the code to assure that unregistered client's
4168 are not handled when it is not allowed. Affected file
4171 * Added `bool registered' fields to all
4172 silc_idlist_[server|client]_get_* routines to indicate whether
4173 the fetched client needs to be registered or not. Affected
4174 file silcd/idlist.[ch].
4176 * Add your own entry as registered to the ID cache in the
4177 server. Affected file server.c.
4179 * Fixed a bug in silc_server_new_server. The SilcServer was
4180 set as the new server's context instead of SilcServerEntry.
4181 This naturally caused some weird bugs.
4183 * Added "updated" field the SilcChannelEntry which indicates
4184 the time since the channel entry was last accessed. This
4185 can be used to determine whether it is necessary to
4186 announce the channel after backup resuming protocol.
4187 Affected files silcd/idlist.[ch].

4210 file irssi/src/fe-common/core/themes.c.
4212 * Fixed double free in client library in the file
4213 lib/silcclient/client.c when disconnecting from server.
4215 * Applied double free patch from cras to Irssi SILC client.
4216 Affected files irssi/src/core/[modules/expandos].c
4218 * Fixed the disconnection handling to Irssi SILC Client.
4219 The application must call silc_client_close_connection
4220 in ops->connect client operation in case of failure of
4221 the connection. Affected file is
4222 irssi/src/silc/core/client_ops.c.
4224 * Do not set sock->protocol to NULL in the function
4225 silc_client_close_connection after executing the protocol's
4226 final callback since the sock might not be valid anymore.
4227 Affected file lib/silcclient/client.c.
4229 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4231 * Do not enable SILC_THREADS if the linking with libpthread
4232 did not happen. Affected file configure.in.pre.
4234 * Added notion to protocol specification that server must
4235 verify the sent authentication payload with CMODE when
4236 setting the channel founder key. Implemented it to the
4237 server. Affected file silcd/command.c.
4239 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4241 * Added _EXTRA_DIST SILC distribution variable to the
4242 distributions file. It is used to conditionally add extra
4243 files or directories to the specific distribution. Affected

4255 file is silcd/server.c.
4257 * Fixed the lib/silcske/groups.c to work now also with GMP
4258 MP library. The string conversion did not work when using
4259 specific base and the base is indicated in the string as well.
4261 * Created win32/ directory which now includes MSVC++ specific
4262 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4263 It will appear only in the toolkit distribution
4265 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4267 * Changed the key material distribution function in case when
4268 the hash output is too short. The data is now concatenated
4269 a bit differently than it used to. Made the change to the
4270 SKE protocol specification.
4272 * Added better GMP detection to configure.in.pre. A patch
4275 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4277 * Fixed a minor bug in SKE that might cause some problem on
4278 some platforms. Affected file lib/silcske/silcske.c.
4280 * Added the cookie checking for initiator in the SKE. It checks
4281 that the responder returns the sent cookie unmodified. The
4282 affected file is lib/silcske/silcske.c. Added new SKE
4283 error type INVALID_COOKIE that can be sent during the
4284 negotiation. Fixed some memory leaks as well.
4286 * Added the "invalid cookie" error message to Irssi SILC client's
4289 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4291 * Added `task_max' field to the SilcClientParams to indicate
4292 the maximum tasks the scheduler can handle. If set to zero,
4293 default values are used. Affected file lib/silcclient/silcapi.h.
4295 * Fixed memory leaks in silc_client_close_connection. Affected
4296 file lib/silcclient/client.c.
4298 * Added silc_client_del_client_entry to client library to free
4299 all memory of given client entry. Affected file is
4300 lib/silcclient/idlist.[ch].
4302 * Added new functions silc_client_del_channel and
4303 silc_client_del_server to delete channel and server entries.
4304 Affected file lib/silcclient/[silcapi.h/idlist.c].
4306 * Removed silc_client_del_client_by_id from silcapi.h.
4308 * Fixed the INFO command to return the server's own info
4309 correctly when querying by Server ID. Affected file is
4312 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4314 * Removed the non-blocking settings in WIN32 code in the
4315 silc_sock_[read/write] and added SleepEx instead. Affected
4316 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4317 of input data is now checked with FIONREAD and ioctlsocket.
4319 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4321 * Call silc_schedule_task_del_by_context in the
4322 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4323 Affected file lib/silccore/silcprotocol.c.
4325 * Call silc_protocol_cancel for active protocols in the
4326 silc_server_close_connection if the funtion
4327 silc_server_free_sock_user_data has not been called.
4328 Affected file silcd/server.c.
4330 * Generic tasks cannot be deleted using the del_by_fd
4331 task deleting function since generic tasks does not match
4332 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4334 * Added a notion to SILCOPER help file that the SILCOPER works
4335 only on router server, not on normal server.
4337 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Added for WIN32 support for the new scheduler as well.
4340 Affected file lib/silcutil/win32/silcwin32schedule.c.
4342 * Fixed the SHA1 implementation to work on various platforms.
4344 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4346 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4347 API. It is part of the scheduler now. Everything else is
4348 as previously but some functions has changed their names.
4349 Checkout the lib/silcutil/silcschedule.h for the interface.
4350 Updated all applications to use the new interface. Affected
4351 files are lib/silcutil/silcschedule.[ch].
4353 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4355 * Found a bug in the SKE implementation. The HASH value,
4356 specified by the protocol, was not computed correctly. The
4357 public key of the responder was not added to the computation
4358 even though it is mandatory. Affected file lib/silcske/silcske.c.
4359 This unfortunately causes incompatibilities with older
4360 clients and servers.
4362 * Added WIN32 specific network init and uninit functions:
4363 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4364 the Winsock2. Affected file lib/silcutil/silcnet.h and
4365 lib/silcutil/win32/silcwin32net.c.
4367 * Set the socket always to nonblocking mode on WIN32 after
4368 reading data or writing data. Affected file is
4369 lib/silcutil/win32/silcwin32sockconn.c.
4371 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4373 * Fixed various compilation problems under WIN32. Affected
4374 files lib/silcutil/win32/silcwin32thread.c and
4375 lib/silcutil/win32/silcwin32schedule.c.
4377 * Removed all _internal.h #includes from public header
4378 files. Internal headers must never be included from
4381 Removed also the lib/silcske/payload_internal.h file.
4383 * All include files that may be needed (public and some others
4384 included by the public headers) by application developers are
4385 now copied to the ./includes directory. It does not copy any
4386 internal headers. Affected file Makefile.defines.pre and all
4387 Makefile.am's under lib/ and subdirs.
4389 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4391 * Do not change the ~/.silc directory's permissions automatically.
4392 Affected file irssi/src/silc/core/clientutil.c.
4394 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4396 * Do not cancel the protocol in silc_server_close_connection
4397 it might cause recursion. Now cancelled in the function
4398 silc_server_free_sock_user_data. Affected file silcd/server.c.
4400 * Fixed the silc_server_remove_clients_by_server to regenerate
4401 the channel keys correctly finally. Added also new function
4402 silc_server_remove_clients_channels to actually do it.
4403 Affected file silcd/server.c.
4405 * Fixed the silc_server_new_channel to not crash by giving
4406 wrong router to the new channel. Affected file is
4407 silcd/packet_receive.c.
4409 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4411 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4412 which is given as argument to the silc_client_alloc now.
4413 It can be used to configure the client and set various parameters
4414 that affect the function of the client.
4416 * The USERS command in server did not check whether the channel
4417 is private or secret. Affected file silcd/command.c.
4419 * Added new argument to the USERS command in protocol specification.
4420 The USERS command now can take the channel name as argument
4421 as well. Added support for this in client and server and
4422 updated the protocol specs.
4424 * Completed the GETKEY command in client. It can be now used
4425 to fetch also servers public key not only some clients.
4426 Affected files lib/silcclient/command[_reply].c.
4428 * Added silc_client_get_server to return server entry by the
4429 server name. Affected files lib/silcclient/silcapi.h and
4432 * Redefined the IDENTIFY command in protocol specification to be
4433 more generic. It now can be used to query information about
4434 any entity in the SILC Network, including clients, servers and
4435 channels. The query may be based either the entity's name
4436 or the ID. Added support for this in both client and server.
4438 Affected files silcd/command.c and lib/silcclient/command.c
4439 and command_reply.c.
4441 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4442 the _from_client and _from_server functions. Affected file
4445 * Added silc_client_get_channel_by_id_resolve to the file
4446 lib/silcclient/silcapi.h to resolve channel information by
4447 its ID. Added also silc_client_get_channel_by_id that
4448 does not resolve it from the server.
4450 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4452 * Added SilcServerEntry context into the client library
4453 to represent one server. The INFO command now allocates
4454 these to save the resolved server info. For now on the
4455 client library will also keep information about servers,
4456 connected and resolved with INFO.
4458 The INFO command now allocates the SilcServerEntry context
4459 and saves the server info there. The COMMAND_REPLY in
4460 the INFO now returns the parameters to application in
4461 same order as defined in the protocol specification.
4463 The entries are cached in the client->server_cache.
4465 * The INFO command is now issued after received the Client ID
4466 from the server. Affected file lib/silcclient/client.c.
4468 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4469 to the application as the mode changer might be server.
4470 It is guaranteed that NULL is not returned anymore to the
4471 application. Affected file lib/silcclient/client_notify.c.
4473 The ID Type is now also passed to the application so that
4474 it can check whether the returned entry is SilcClientEntry
4477 Added new function silc_client_get_server_by_id to return
4478 the server entry by ID. Affected files are the
4479 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4481 * Do not create the channel in the Irssi SILC Client when issuing
4482 the JOIN command but when received the sucessful JOIN command
4483 reply. Otherwise the channel might get created even though we
4484 could not join it. The Affected file is
4485 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4487 * Fixed a channel joining bug in router. The router must also
4488 check the channel modes, invite and ban lists etc. when serving
4489 the JOIN command sent by normal server. Affected file is
4490 silcd/command.c. The router now resolves the client's
4491 information from the server who sent the JOIN command if it
4492 does not know it, and processes the JOIN command only after
4495 * Changed the SilcCommandCb to take new argument; void *context2.
4496 Affected file lib/silccore/silccommand.h
4498 The second argument in the command callbacks in the server now
4499 includes the SilcServerCommandReplyContext if the command was
4500 called as pending command callback from the command reply.
4501 Otherwise it is NULL. When called as pending the status of the
4502 command reply will be checked and if it was erronous the
4503 error will be sent to the original sender of the command.
4504 This way the client always receives the error messages even
4505 though the server was actually the one who received the error
4506 when it resent the command to router, for example. Affected
4507 files silcd/command[_reply].[ch].
4509 * Fixed sending WHOWAS command's error message to client if
4510 the requested client could not be found. It was missing.
4513 * Changed the CMODE and CUMODE commands reply arguments in the
4514 protocol specification. The Channel ID is now sent in both
4515 of the commands to identify the channel. Implemented this
4516 new feature to the client and server. Affected files
4517 lib/silcclient/command_reply.c and silcd/command.c.
4519 * Made better checks for invite and ban lists in the JOIN
4520 command in server. Affected file silcd/command.c.
4522 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4524 * The server now performs the incoming host IP/DNS lookup
4525 using the silc_socket_host_lookup and thus does not block
4526 the server anymore. Affected file silcd/server.c.
4528 * Completed the multi-thread support for SILC Scheduler in
4529 the lib/silcutil/silcschedule.c.
4531 * Fixed the configure.in.pre to detect the pthread correctly
4534 * Fixed a deadlock in silc_task_queue_wakeup in the file
4535 lib/silcutil/silctask.c.
4537 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Added new function silc_schedule_wakeup that is used in
4540 multi-threaded environment to wakeup the main thread's
4541 schduler. It needs to be used when a thread adds a new task
4542 or removes a task from task queues. After waking up, the
4543 scheduler will detect the task queue changes. If threads
4544 support is not compiled in this function has no effect.
4545 Implemented the wakeup mechanism to both Unix and WIN32
4546 systems. Affected files are lib/silcutil/silcschedule.[ch],
4547 lib/silcutil/unix/silcunixschedule.c and the
4548 lib/silcutil/win32/silcwin32schedule.c.
4550 * Added new function silc_task_queue_wakeup to wakeup the
4551 scheduler by the specified task queue. Affected file
4552 lib/silcutil/silctask.[ch].
4554 * The silc_socket_host_lookup_start now wakes up the scheduler
4555 after adding the timeout task. Affected file is
4556 lib/silcutil/silcsockconn.c.
4558 * The silc_socket_host_lookup is synchronous now if the threads
4559 support is not compiled in. However, the callback is still
4560 called asyncronously through the scheduler, anyway. Affected
4561 file lib/silcutil/silcsockconn.c.
4563 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4565 * Added new function silc_socket_host_lookup to perform
4566 asynchronous IP and FQDN lookups for the socket connection.
4567 Affected files lib/silcutil/silcsockconn.[ch].
4569 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4571 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4572 that may or may not compile the mutex support in.
4574 Changed the silc_mutex_alloc interface. It allocates the
4575 mutex now to the sent pointer and returns TRUE or FALSE.
4577 Affected file lib/silcutil/silcmutex.h.
4579 * Wrote the SILC Task Queue interface to support multi-threads.
4580 Affected file lib/silcutil/silctask.[ch].
4582 * Wrote the SILC Scheduler to support multi-threads. Affected
4583 file lib/silcutil/silcschedule.c.
4585 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4587 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4588 in lib/silcutil/win32/.
4590 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4592 * Defined SILC Mutex API and SILC Thread API and implemented
4593 them for Unix. Affected files are
4594 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4595 lib/silcutil/unix/silcunixmutex.c and
4596 lib/silcutil/unix/silcunixthread.c.
4598 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4600 * Fixed the silc_server_remove_clients_by_server's channel
4601 key re-generation. The hash table handling was incorrect
4602 and would not work with many channels. Affected file is
4605 * Fixed some memory leaks around the server code.
4607 * Rewrote the silc_server_get_users_on_channel to support IPv6
4608 based Client ID's. Affected file silcd/server.c.
4610 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4611 specification. However, a separate document must be written
4612 to define the detailed signing procedure and the payload
4613 associated with the flag. Defined the flag to the
4614 lib/silccore/silcchannel.h as well.
4616 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4618 * Changed the dynamic tables to static size tables in the
4619 lib/silccrypt/silchmac.c.
4621 * Removed GCC dependencies from the code. A patch by cras.
4623 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4625 * Do not show the error "Error receiving packet bla bla"
4626 in server if it really was not an error (-2 means that reading
4627 is pending). Affected file silcd/server.c.
4629 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4631 * Fixed a possible crash in silc_server_remove_clients_by_server
4632 in silcd/server.c. Fixed there also some memory leaks.
4634 * Fixed the silc_idlist_replace_client_id. It could replace
4635 wrong key in the hash table. Affected file silcd/idlist.c.
4637 * Do not check whether there are global users on the channel
4638 if the channel->global_users is FALSE. Affected functions
4639 silc_server_remove_from_one_channel and
4640 silc_server_remove_from_channels in silcd/server.c. Also,
4641 do not check if the removed client is local as we can be
4642 sure that global client was not removed from the channel
4643 and checking for global users is not needed.
4645 * The silc_server_remove_clients_by_server now re-generates
4646 the channel keys correctly for those channels that had
4647 clients removed from them. Affected file silcd/server.c.
4649 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4651 * Found the reason of random crashes in the server. We weren't
4652 ignoring the SIGPIPE signal (which can be sent in write())
4653 and it crashed the server. Affected file silcd/silcd.c.
4655 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4657 * Assure that sock->user_data is not NULL in the function
4658 silc_server_packet_send in silcd/packet_send.c.
4660 * Disconnect the remote connection if it could not be added
4661 to any ID lists in the server. The affected file is
4664 * Check in silc_server_packet_send[_real/dest] that the
4665 socket is not disconnecting and ignore the data if it is.
4666 Affected file silcd/packet_send.c.
4668 * Define inline to __inline on native WIN32 compilation.
4669 Affected file includes/silcwin32.h.
4671 * Added some explicit type casts for inline code since MSVC
4672 require them. Affected files lib/silcutil/silcbuffer.h,
4673 lib/trq/silcdlist.h and lib/trq/silclist.h.
4675 * Print warning in log files from now on if the packet
4676 decryption fails. Affected file silcd/server.c.
4678 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4680 * Changed the `say' client operation's interface to accept
4681 new `type' argument to indicate the type of the message sent
4682 by the library. The application may filter the library's
4683 messages according the type. The affected file is the
4684 lib/silcclient/silcapi.h.
4686 * Added two new functions to lib/silcclient/silcapi.h:
4687 silc_client_del_client and silc_client_del_client_by_id.
4688 Affected file lib/silcclient/idlist.c.
4690 * Moved the clientincludes.h from includes/ to silc/ and
4691 serverincludes.h from includes/ to silcd/.
4693 * The modes for the CMODE and CUMODE are now passed as
4694 uint32 for application with COMMAND_REPLY. The affected
4695 file is lib/silcclient/command_reply.c.
4697 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * /WHOIS without arguments shows client's own information.
4700 Affected file lib/silcclient/command.c.
4702 * Changed PING to not accept any arguments. The specs
4703 says that client can ping only the connected server so
4704 requiring an argument is not needed. Affected file is
4705 lib/silcclient/command.c.
4707 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4709 * Fixed a fatal bug in private message sending and reception
4710 encryption and decryption when using private message keys.
4711 The implementation was incorrect and did not follow the
4712 specification. It causd that some of the message were
4713 lost since it did not use the sending and receiving keys
4714 as the protocol suggests. This has been fixed and will cause
4715 incompatibilities with older clients when sending private
4716 message encrypted with private message keys. Affected files
4717 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4718 and various other in Irssi SILC Client.
4720 Added `responder' boolean argument to the functions
4721 silc_client_add_private_message_key[_ske] to indicate when
4722 the key is added as responder or initiator of the key
4725 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4727 * Removed the silc_ske_check_version function and created
4728 a SilcSKECheckVersion callback. Added also a function
4729 silc_ske_set_callbacks that is now used to set all SKE
4730 callbacks. The callback functions are not given to
4731 the SKE functions anymore, but this function is used to
4734 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4736 * Added `silc_version' argument to the silc_client_alloc
4737 to define the version of the application for the library.
4738 The library will use the version string to compare it
4739 against the remote host's (usually a server) version
4740 string. Affected file lib/silcclient/silcapi.h
4742 * Added the KE protocol context to Key Agreement context
4743 in client library so that we can abort the SKE if it
4744 is in process when we get timeout. Affected file is
4745 lib/silcclient/client_keyagr.c.
4747 * Do not resolve the client ID forever if it returns in the
4748 first time that such client does not exist. This was done
4749 for example with private message. Affected file is
4750 lib/silcclient/client_prvmsg.c.
4752 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4754 * Do not add regex.h for WIN32. The affected file
4755 includes/silcincludes.h.
4757 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4758 not work yet 100%. It generates the DLL's automatically
4759 when compiling with --with-win32 under cygwin.
4761 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4763 * lib/contrib/regex.c is not compiled on WIN32.
4765 * Added silc_net_get_socket_opt function to the
4766 lib/silcutil/silcnet.h.
4768 * Added includes/silcwin32.h for WIN32 specific includes
4771 * Do not use ptime structure or any of the posix process
4772 functions on WIN32 in lib/silccrypt/silrng.c.
4774 * Added silc_gettimeofday to provide generic function
4775 for struct timeval on all platforms. Added the function
4776 to lib/silcutil/silcutil.h.
4778 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4780 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4781 library as they clearly belong there. As a plus side we
4782 can make the actual socket connection routines platform
4785 Added also new generic function silc_socket_read and
4786 silc_socket_write (that used to be silc_packet_[read/write].
4787 The implementation of these are platform specific.
4789 * Added WIN32 specific routines of silc_socket_[read/write]
4790 to lib/silcutil/win32/silcwin32sockconn.c.
4792 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4794 * Added preliminary support for native WIN32 compilation under
4795 cygwin (using the -mno-cygwin option for GCC) to the
4796 ./configure.in.pre. The --with-win32 now prepares the
4797 compilation for native WIN32.
4799 * Rewrote the SILC Scheduler interface in the file
4800 lib/silcutil/silcschedule.h. The scheduler is now context
4801 based and does not have anymore any global static scheduler.
4802 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4803 and created lib/silcutil/win32 directory for WIN32 based
4806 * Added Unix specific network routines to the
4807 lib/silcutil/unix/silcunixnet.c and the old
4808 lib/silcutil/silcnet.c includes now only generic routines.
4810 Added WIN32 specific network routines to the
4811 lib/silcutil/win32/silcwin32net.c.
4813 * Added Unix specific utility functions from the
4814 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4816 * Added WIN32 SILC Scheduler to the file
4817 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4820 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * Do not handle JOIN notify in the server if the target client
4823 is not registered (idata->registered == FALSE). The affected
4824 file is silcd/packet_receive.c.
4826 * Update the nickrec->founder in event_cumode in the Irssi SILC
4827 client. Affected file irssi/src/silc/core/silc-channels.c.
4829 * Fixed the CUMODE_CHANGE notify handling in the server when
4830 server and router are announcing their clients on channels.
4831 Now the mode changes are saved and notified correctly. The
4832 affected file is /silcd/packet_receive.c.
4834 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4835 They really did not replace the cache entry in the ID Cache.
4836 Now they do that. Affected file silcd/idlist.c.
4838 * Fixed the KICK notify handling in the Irssi SILC client to
4839 update the channel records so that the kicked client does not
4840 appear to be on the channel. The affected file is
4841 irssi/src/silc/core/silc-channels.c.
4843 * Always update the conn->current_channel when executing command
4844 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4846 * Fixed the KILL notify handling in Irssi SILC client to remove
4847 the killed client on all channels.
4849 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4851 * Fixed the silc_parse_command_line to remove extra spaces
4852 from the start and end of the arguments. Affected file is
4853 lib/silcutil/silcutil.c.
4855 * Cancel and free any active protocol in the function
4856 silc_server_close_connection. Affected file silcd/server.c.
4858 * Cancel and free any active protocol in the function
4859 silc_client_close_connction. Affected file is
4860 lib/silcclient/client.c.
4862 * Do not execute the KILL command for clients that are in
4863 history (ie. they are not in the network). Affected file is
4866 * Fixed KILL notify handling, client does not crash anymore.
4867 Affected file irssi/src/silc/core/silc-channels.c.
4869 * Reduced the default packet buffer size from 2048 to 1024 in
4870 lib/silccore/silcpacket.c.
4872 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4873 counter to the SKE context that is incresed when the SKE library
4874 performs async operation outside the library. If the outside
4875 process frees the SKE context and FREED status will be set
4876 and the library will detect after the sync operation that the
4877 libary is freed. The affected files are
4878 lib/silcske/silcske[_status].[ch].
4880 * Resolve the client entry information in the function
4881 silc_client_channel_message to assure that NULL pointer is not
4882 passed as client entry to the application. */
4884 * Fixed the task timeout calculation to assure that there is
4885 never negative timeouts. The affected file is
4886 lib/silcutil/silcschedule.c.
4888 * Fixed the channel user mode notification sending in server.
4889 It was sent point-to-point to the router (or to server by router)
4890 but it needs to be destined to a channel. The routines now
4891 supports sending the channel user mode notifys to the channels
4892 when announcing clients and channels. Affected files are
4893 silcd/server.c and silcd/packet_receive.c.
4895 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4896 It did not actually replace the old channel entry in the cache.
4897 Affected file lib/silcclient/client_notify.c.
4899 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Fixed a possible crash in silc_packet_send_prepare. It now
4902 assures always that there is enough space in the buffer and
4903 at the tail area of the buffer (for MAC).
4905 Fixed the inbound buffer reallocation in silc_packet_read.
4906 It was old code and did not handle the reallocation correctly.
4909 The affected file is lib/silccore/silcpacket.c.
4911 * Fixed buffer overflow in silc_parse_nickname in the file
4912 lib/silcutil/silcutil.c.
4914 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * make install generates new server keys only if there is not
4919 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4922 Added check that if the NOREPLY is set then we will not send
4923 the away message. This avoids infinite loop of away messages
4924 if both clients are away. The affected file is
4925 lib/silcclient/client_prvmsg.c.
4927 * Fixed client crash if /NICK was given without arguments.
4928 Affected file lib/silcclient/command.c.
4930 * Server does not send the invite list in INVITE command back
4931 to the client if the list was not altered. Added this notion
4932 to the protocol spec as well. Affected file silcd/command.c.
4934 Fixed possible crash in INVITE command by checking the
4935 value of silc_server_get_client_route command.
4937 * Fixed the INVITE notify type handling. The arguments are now
4938 taken in correct order and client does not crash. The affected
4939 file is irssi/src/silc/core/silc-channels.c.
4941 Removed the "Inviting xxx to channel" message from the
4942 client library away and let the application handle it.
4943 Affected file lib/silcclient/command.c. Added that message
4944 to Irssi SILC client's message formats.
4946 * Fixed CMODE command crash in client. It now checks the
4947 amount of arguments correctly and does not crash. The affected
4948 file is lib/silcclient/command.c.
4950 * Do not create new channel automatically in silc_channels_join
4951 but check whether the channel by that name already exists.
4952 Affected file irssi/silc/core/silc-channels.c.
4954 * Do not send the SERVER_SIGNOFF to router if the disconnected
4955 entity was the router. Affected file silcd/server.c.
4957 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4958 SILC client as it was missing from there.
4960 Added the handling of the KICK notify to the Irssi SILC client
4961 as it was missing. Added "you have been kicked" message to
4962 Irssi SILC client's message modules formats.
4964 Added the handing of the KILL notify to the Irssi SILC client
4965 as it was missing. Added the kill message module formats
4968 The affected file is irssi/src/silc/core/silc-channels.c.
4970 * The router did not save the channel mode the server announced.
4971 Affected file silcd/packet_receive.c.
4973 * Fixed a possible crash in INFO command in server. If the
4974 server did not provide the server info it crashed. Affected
4975 file silcd/command.c.
4977 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Fixed the GETKEY command in the server to check also the
4980 global list. Otherwise the GETKEY would not work correctly
4981 in normal SILC server. Affected file silcd/command.c.
4983 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Fixed GETKEY crash, it crashed if the command did not succseed.
4987 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4990 is now real and not just an macro interface to GMP.
4992 Removed the entire GMP from the source tree and imported new
4993 NSS MPI library instead. Reason for removing GMP is that it is
4994 extremely large and compiles extremely slow. The NSS MPI
4995 is only a few files and compiles in less than 10 seconds.
4996 The speed is also about the same as GMP. The MPI is imported
4997 to lib/silcmath/mpi.
4999 If the system has GMP installed we will still use the GMP.
5000 If it is not then the NSS MPI will be compiled.
5002 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Merged a long nickname (127 characters long) crash bugfix from
5005 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5007 * Merged a freed memory reference bugfix from Irssi CVS tree.
5008 Affected file irssi/src/core/commands.c.
5010 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Added the server's public key sving and verification to the
5013 server when performing the SKE. This was missing and the
5014 remote server's (or router's) public key was accepted without
5015 checking whether we have it previously or trust it at all.
5016 Affected file silcd/protocol.c.
5018 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Check in the silc_server_timeout_remote if protocol is active
5021 and make sure that the protocol's final callback is called so
5022 that all memory if freed. Affected file silcd/server.c.
5024 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * silc_server_whois_send_reply crashed the server if the nickname
5027 was 127 characters long. Affected file silcd/command.c.
5029 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Added sanity check to the silc_server_new_client. If the hostname
5032 is provided inside username then check that the provided hostname
5033 really is the same as the resolved one. If the hostname was not
5034 resolved then check it from the public key. Affected file is
5035 silcd/packet_receive.c.
5037 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5038 if the server disconnected us and the connection is not valid
5039 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5041 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5042 the library to the lib/silcutil/silcutil.[ch].
5044 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Close log file after open. Affected file
5047 lib/silcutil/silclog.c.
5049 * Check whether sock == NULL in silc_client_send_packet and return
5050 if it is. Affected file lib/silcclient/silcclient.c.
5052 * Check rec->entry == NULL in the Irssi SILC Client before
5053 sending the channel message. Affecte file is
5054 irssi/src/silc/core/silc-servers.c.
5056 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Merged a splitted window bugfix from Irssi CVS tree. The
5059 affected file is irssi/src/fe-text/textbuffer-view.c.
5061 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5062 It did not print nickname.
5064 * Improved the distributions system a bit.
5066 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5069 irssi/src/fe-text/gui-window.c.
5071 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5072 to in-active server. The affected file is
5073 irssi/src/silc/core/client_ops.c.
5075 * Resolve the client in USERS command reply if the entry does
5076 not have username resolved. The affected file is
5077 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5078 command to WHOIS command to really resolve stuff. The USERS
5079 is not used any more in any critical section so WHOIS can
5080 be used even though it might be slower than IDENTIFY.
5082 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5085 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Changed the protocol API a bit more consistent in the
5088 lib/silccore/silcprotocol.[ch].
5090 * Changed the following headers to ROBODoc format:
5092 lib/silccore/silcpayload.h
5093 lib/silccore/silcprotocol.h
5094 lib/silccore/silcsockconn.h
5096 All core library headers are now formatted.
5098 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Fixed a bug in Irssi SILC client; do not show that you are
5101 server/router operator if you really are not. Affected file is
5102 irssi/src/silc/core/client_ops.c.
5104 * Renamed silc_command_free_payload to silc_command_payload_free.
5105 Affected file lib/silccore/silccommand.h
5107 * Added silcmath.h to include the prototoypes of various routines
5108 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5111 * Changed the following headers to ROBODoc format:
5113 lib/silccore/silcchannel.h
5114 lib/silccore/silccommand.h
5115 lib/silccore/silcid.h
5116 lib/silccore/silcidcache.h
5117 lib/silccore/silcmode.h
5118 lib/silccore/silcnotify.h
5119 lib/silccore/silcpacket.h
5120 lib/silcmath/silcmath.h
5122 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Added checking to the server code not to start the server if
5125 ciphers and stuff are not configured properly. Affected files
5126 silcd/serverconfig.[h] and silcd/server.c.
5128 * Changed the layout of the header files of the public interfaces
5129 in the SILC libraries. The new layout supports ROBODoc
5130 documentation tool (and some others) so that it is easy to create
5131 a library reference manual. All the other headers and source
5132 code must still follow the CodingStyle document. Also source
5133 code must not include these ROBODoc stuffs, only the headers.
5134 Furthermore, all public interface headers must now be named
5135 by using `silc' prefix, example: silcapi.h, silccipher.h.
5136 Some files were renamed due to this. All the other headers
5137 must not be used as public interfaces. I will update the
5138 CodingStyle document later. Changed following headers, so far:
5140 lib/silcclient/silcapi.h
5141 lib/silccore/silcauth.h
5142 lib/silccore/silcprivate.h
5143 lib/silccrypt/silcdh.h
5145 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Removed silc_client_packet_send_flush from the client library
5150 as it is not needed. Affected file lib/silcclient/client.[ch].
5152 * Added printing of message of unresolved authentication method
5153 to the Irssi SILC client. Added it to the module formats.
5154 Removed the same message from the client library.
5156 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Added new distribution feature, DISTLABEL. Every distribution
5159 can define own preprocessor label that can be used in the
5160 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5161 file distributions, acconfig.h.pre and prepare.
5163 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Added Makefile.defines_int to include the actual definitions
5166 for Makefile.defines.in. Tested the new distribution system,
5167 created distributions and tested installation.
5169 * Added AWAY message printing to the Irssi SILC client. Added
5170 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5172 * Added SCONNECT command to call the SILC's CONNECT command.
5173 Cannot use CONNECT directly since Irssi uses that internally.
5174 Affected file irssi/src/silc/core/silc-servers.c.
5176 Added ACTION local command. It is same as ME command but takes
5177 the channel as mandatory argument.
5179 Rewrote some of the Irssi's help files to suite for SILC
5182 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added Makefile.defines[.in] that should for now on be included
5185 in all Makefile.am file in the source tree. That file includes
5186 all common compilation definitions for SILC source tree.
5188 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Minor changes to the ./prepare script to change the package
5191 name according the distribution name to the configure.in.
5193 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Created new distribution system. Added file `distributions'
5196 that defines all the distributions that can be created out of
5197 the SILC source tree. The ./prepare script now reads that
5198 file to determine how to prepare the distributions. The
5199 first argument to the ./prepare is the name of the distribution
5200 and second is the version of the distribution. If given
5201 without arguments it creates the default (toolkit) distribution
5202 with the default version (defined in ./prepare).
5204 All Makefile.am files that are subject to the distributions
5205 are now named as Makefile.am.pre. These are ./Makefile.am
5206 and lib/Makefile.am. Others may be changed later.
5208 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Added invite list, ban list, some key management and connection
5211 error message printing to module formats in the Irssi SILC client.
5213 * Added new silc_client_set_away_message to set the away message
5214 that is back to the person who sent private message. The
5215 affected file lib/silcclient/silcapi.h and the
5216 lib/silcclient/client_prvmsg.c.
5218 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Fixed the private message sending in the Irssi SILC client,
5221 added local command KEY to the Irssi SILC client.
5223 Added key management and key agreement message formats to the
5224 irssi/src/fe-common/silc/module-formats.[ch].
5226 Added USERS (alias WHO) printing, server/router operator
5227 indication and LIST command printing to the module formats.
5229 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Fixed channel joining notify handling, cumode notify handling
5232 from Irssi SILC client.
5234 * Added SILC specific module-formats to the Irssi SILC client so
5235 that SILC specific message hilighting, colors etc is possible.
5236 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5238 Added channel mode, channel user mode, actions, notices,
5239 whois and whowas printing to the the module-formats.c.
5241 * Fixed a bug in channel deletion in the server. The channel
5242 is not left to the cache even if the channel founder auth mode
5243 is set when there are no users anymore on the channel. Affected
5244 file silcd/server.c.
5246 * The silc_net_localhost now resolves the entire hostname including
5247 the domain name. Affected file lib/silcutil/silcnet.c.
5249 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Changed the ask_passphrase client operation to be ascynchronous.
5252 It has now a completion callback and a context that the
5253 application must call after it has got the passphrase from
5254 the user. Affected files lib/silcclient/silcapi.h,
5255 lib/silcclient/protocol.c, lib/silcclient/command.c and
5258 Added SilcAskPassphrase callback that the application calls
5259 to deliver the passphrase to the library.
5261 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5262 The public key verification and especially a certificate
5263 verification is asynchronous procedure.
5265 Added new SILC_SKE_STATUS_PENDING status to indicate the
5266 request is pending and a callback will be called to finalize
5269 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5270 indicate that remote end did not send its public key (or
5271 certificate), even though we require it. Added check for this
5272 condition in the SKE. This was a security bug, now fixed.
5274 Defined new SilcSKEVerifyCbCompletion callback that is called
5275 when the verification process is completed.
5277 The affected files lib/silcske/silcske_status.h and
5278 lib/silcske/silcske.[ch].
5280 * Changed the verify_public_key client operation to be async
5281 as well. Defined SilcVerifyPublicKey callback that is used to
5282 indicate the success of the public key verification process.
5284 Changed the server and client to use the new async client
5287 * Changed the Irssi SILC client's internal scheduler to be called
5288 twice as many times as it used to be. As a result the client
5289 should be a bit faster now. Affected file is
5290 irssi/src/silc/core/silc-core.c.
5292 * Added support to Irssi SILC client of asynchronous public key
5293 verification and passphrase inquiry. Affected file is
5294 irssi/src/silc/core/silc-core.c.
5296 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Do not say "You have left channel %s" in client library.
5299 Moved it to the application. Affected files are
5300 lib/silcclient/command.c and silc/client_ops.c.
5302 * Fixed silc_client_get_clients. Command context was not
5303 duplicated and was freed memory in the callback. Affected
5304 file lib/silcclient/idlist.c.
5306 * Do not say "you are now talking..." on JOIN command in the
5307 client library. The appliation must handle it.
5309 * Do not say ".. changed topic to" in command reply in the
5310 client libary. The application must handle it.
5312 * Fixed TOPIC command sending in the client library.
5314 * Fixed a memory leak in silc_client_command_free in the file
5315 lib/silcclient/command.c.
5317 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Imported a modified version of Irssi client to the source tree.
5320 The Irssi will be used to create a new client called
5321 Irssi SILC. Imported to irssi/.
5323 Added silc_core_init_finish function to the Irssi. Affected
5324 file irssi/configure.in.
5326 A lot changes in the Makefile.ams around the irssi tree.
5328 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * Do not rehash if the new size is same as the old size of the
5331 hash table, in the silc_hash_table_rehash*. The affected file
5332 lib/silcutil/silchashtable.c.
5334 * Replaced hash_table_del_by_context calls from the server
5335 (when channel->user_list and client->channels) to the
5336 hash_table_del as it is sufficient and faster.
5338 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added silc_hash_table_list, silc_hash_table_get and the
5341 SilcHashTableList structure to provide an alternative way to
5342 traverse the hash table. The affected files are
5343 lib/silcutil/silchashtable.[ch].
5345 * Changed the server's idlist routines to use the hash table
5346 routines to optimize the code.
5348 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Replaced the client entry's `channel' list and channel entry's
5351 `user_list' list to hash tables for optimized lookup. Changed
5352 the code to use the hash table interface around the code.
5353 Affected file lib/silcd/idlist.[ch].
5355 * Added `auto_rehash' boolean argument to the function
5356 silc_hash_table_alloc to indicate whether the hash table should
5357 auto-rehash when it thinks is appropriate time. It will
5358 increase the hash table size if the there is twice as much
5359 entries in the table than the size of the table, and will
5360 decrease the size if there are twice as less entries than
5361 the size of the table.
5363 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5367 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * silc_idcache_purge_by_context deletes the entry now by context
5370 as it is supposed to do. Affected file lib/silccore/idcache.c.
5372 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5373 client is not anymore valid (WHOWAS givens the info) and not
5374 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5376 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Removed the `data' and `data_len' arguments from the ID Cache
5379 interfaces and added `name' argument. ID Cache does not handle
5380 anymore the binary data only a names associated with given ID.
5382 * When hashing a Client ID with silc_hash_id the entire ID is
5383 not hashed anymore, instead only the hash of the Client ID is
5384 hashed. This way we can access the Client ID from the cache
5385 with Client ID but with the hash of the ID (which is a hash of
5386 the nickname) as well without any difference in performance.
5388 Added also silc_idcache_find_by_id_one_ext to do one on one
5389 searching when we have the actual ID. Added also function
5390 silc_hash_client_id_compare. The affected files are
5391 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5393 * When hashing the name associated with a ID it is always done
5394 in lowercase. This way we can access the cache without worrying
5395 about case-sensitivity, even though, for example nicknames are
5398 * Fixed a bug in server with channel message sending. It put
5399 wrong ID type as destination ID. The affected file
5400 silcd/packet_send.c.
5402 * silc_idcache_del_by_context now deletes from all hash tables
5403 by context. Affected file lib/silccore/idcache.c.
5405 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Changed the client library to use the new ID Cache interface.
5408 Changes around the source tree.
5410 * Added silc_hash_table_rehash_ext to rehash with specific
5411 hash function. Affected file lib/silcutil/silchashtable.[ch].
5413 * Added silc_hash_string_compare to compare two strings in the
5414 hash table. Affected file lib/silcutil/silcutil.[ch].
5416 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Added new function silc_idcache_del_by_context into the
5419 lib/silccore/idcache.[ch].
5421 * Changed the server's ID list routines to use the new ID Cache
5422 interface. Changes around the source tree.
5424 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Added silc_hash_table_del[_by_context]_ext functions in to the
5427 lib/silcutil/silchashtable.[ch].
5429 Removed silc_hash_table_find_all* routines and added new
5430 silc_hash_table_find_foreach to replace them.
5432 Added silc_hash_table_replace_ext function as extended
5433 replacing function. Separated the simple hash table interface
5434 from the extended hash table interface in the file
5435 lib/silcutil/silchashtable.h.
5437 * Fixed minor bugs and changed it to use some of the new
5438 hash table functions in lib/silccore/idcache.c
5440 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Added new function silc_hash_table_find_all to return all keys
5443 in the hash table by the specified key. As the hash table is
5444 collision resistant it also makes it possible to have several
5445 duplicate keys in the hash table. This function may be used to
5446 find all of the keys from the hash.
5448 Added user_context arguments to the SilcHashFunction,
5449 SilcHashCompare and SilcHashDestructor to deliver user specified
5452 Added new fuctions silc_hash_table_find[_all]_ext to do
5453 extended lookup with specified hash and compare functions and
5454 specified user contexts.
5456 Added new function silc_hash_table_add_ext to add the key
5457 with specified hash function and user context.
5459 Added new function silc_hash_table_foreach to traverse all
5460 entrys in the hash table. Added SilcHashForeach callback
5463 Added new function silc_hash_table_del_by_context to delete
5464 the entry only if the context associated with the key matches.
5466 Affected files are lib/silcutil/silchashtable.[ch].
5468 * Removed silc_hash_[server/client/channel]_id and added just
5469 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5470 silc_hash_id_compare to compare two ID's using as the hash table
5471 comparison function. Added also silc_hash_data to hash
5472 binary data and silc_hash_data_compare to compare it.
5474 * Removed silc_idlist_find_client_by_hash as it is not needed
5475 anymore. Affected file silcd/idlist.[ch].
5477 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5478 to use internally the SilcHashTable. The new ID Cache is a lot
5479 faster than the old one. Some of the ID Cache interface was also
5480 rewritten and obsolete and stupid functions were removed.
5482 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Added entry_count field to the SilcHashTable to keep the number
5485 of the entries in the table. Implemented the function
5486 silc_hash_table_rehash. Added new function
5487 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5489 Fixed a minor bug in silc_hash_table_free.
5491 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5492 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5493 into the lib/silcutil/silcutil.[ch].
5495 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Implemented a collision resistant hash table into the
5498 lib/silcutil/silchashtable[ch]. See the header and the source
5499 for the SilcHashTable API.
5501 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Merged dotconf version 1.0.2 into lib/dotconf.
5505 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Do not compile anything in lib/silcsim/* if the SIM support
5508 is not enabled. The tree should now compile without problems
5511 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Compiled the SILC under cygwin. Compiled and tested briefly
5514 without problems. More tests needed. The SIMs didn't compile
5517 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5519 * Fixed possible crash in silc_get_username in the
5520 lib/silcutil/silcutil.c.
5522 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Fixed a va_arg in silc/client_ops.c.
5526 * Oops, RC5 routines were named AES and caused some problems
5527 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5529 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added new SilcIDIP structure into the lib/silccore/id.h and
5532 replaced the old `ip' fields from all SILC ID's to that type.
5533 This is a step towards IPv6 support.
5535 The silc_id_get_len takes now the ID as an extra argument.
5536 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5537 both IPv4 and IPv6 based ID's.
5539 The affected files are lib/silccore/id.[ch] and other files
5540 around the tree using these routines.
5542 * Removed the ID length arguments in server from various
5543 silc_server_send_notify_* routines -> they are not needed
5546 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Fixed memory leak in silc_encode_pem_file in the file
5549 lib/silcutil/silcutil.c.
5551 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Check minor version as well in the SKE. Affected files are
5554 silcd/protocol.c and lib/silcclient/protocol.c.
5556 * Added --identifier option to the server so that an identifier
5557 can be when creating the public key for the server. Affected
5558 file is silcd/silcd.c.
5560 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5561 lib/silccrypt/silcpkcs.c.
5563 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Register default ciphers and stuff when using -C option with
5566 the server. Affected file sildc/silcd.c.
5568 * Put back the servers public key filename format, it is better
5569 than the new one. For now, the client keys are saved with the
5570 new filename format. The affected file silc/client_ops.c.
5572 * Implemented the Cipher API for the rest of the ciphers that
5573 did not implement it or implemented it the wrong way.
5575 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Register default ciphers and stuff when using the -S option
5578 in the client. Affected file silc/silc.c. Same also when
5579 creating new key pair with -C option.
5581 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Fixed the silc_verify_public_key client operation function to
5584 save the public keys differently. The fingerprint is now
5585 used as filename and not the hostname. This way also the
5586 client keys are saved uniquely and not with hostnames. The
5587 affected file is silc/client_ops.c.
5589 * Trimmed the silc_hash_fingerprint function to remove extra
5590 whitespaces from the end of the fingerprint. The affected
5591 file is lib/silccrypt/silchash.c.
5595 * Added silc_cipher_register_default function to register all
5596 default ciphers. It can be used when configuration files
5597 does not exist and the application does not want any specific
5598 ciphers in any specific order.
5600 The SilcDList is now used as silc_cipher_list dynamically
5601 allocated cipher list. Removed the static list all together
5602 and now all ciphers must be allocated to the dynamic list.
5603 The silc_cipher_alloc routine was changed to check only the
5606 All silc_cipher_* routines that used to return int returns
5609 The affected files lib/silccrypt/silccrypt.[ch].
5611 * The same thing was done to silc_hash_* as for silc_cipher_*
5612 routines. Affected files lib/silccrypt/silchash.[ch].
5614 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5615 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5616 Added also silc_pkcs_[un]register[_default] functions.
5617 Removed the data_context from the PKCS API.
5619 * Added silc_hmac_register_default function to register default
5620 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5621 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5622 to unregister all hmacs at once.
5624 * Register the default ciphers, hash functions, PKCSs and HMACs
5625 if client's configuration file does not exist. The affected
5628 * The client did not load the hash functions from the SIM
5629 modules at all. Added support for this. Affected file is
5630 silc/clientconfig.c.
5632 * When decoding public key with silc_pkcs_public_key_decode, check
5633 the supported algorithm only if PKCS are registered. Affected
5634 file lib/silccrypt/silcpkcs.c. The same was done with the
5635 silc_pkcs_private_key_decode.
5637 * Fixed the SILC List routines to keep the list always in order.
5638 It used to change the list's order when traversing the list but
5639 not it preserves the order. Affected file lib/trq/silclist.h.
5641 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Added the client library to use the SilcSocketConnection's
5644 reference counter (by silc_socket_dup) to prevent the bug that
5645 the socket object may be freed underneath async operation.
5647 * The name resolv library checking fixes in the configure.in.pre.
5650 * Created new version of the protocol drafts for future
5651 development. The -03 drafts are the ones that will be changed
5652 in the trunk now and the -02 will remain as they are.
5654 * Send list of CUMODE notifys to the router when announcing
5655 the channel users to the router. Affected file silcd/server.c.
5656 If the router receiving channel founder CUMODE for a channel
5657 that already has channel founder it will send CUMODE notify
5658 to the sender to remove the channel founder rights from the
5659 announced client. Affected file silcd/packet_receive.c.
5661 * The CUMODE notify may now use Server ID as well as the entity
5662 who changes the mode. Updated protocool specs.
5664 * Updated INSTALL and README files.
5666 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * New web pages in the http://silc.pspt.fi. The pages was
5673 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Implemented the [DenyConnectin] config section in the server.
5676 Added silc_server_config_denied_conn to check whether incoming
5677 connection is denied. Affected file silcd/serverconfig.[ch].
5679 * Do not check the ports when checking the incoming configuration
5680 data if the port is 0, meaning any. Affected file is
5681 silcd/serverconfig.c.
5683 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Fixed buffer overflow in silc_string_compare in the file
5686 lib/silcutil/silcutil.c.
5688 * Fixed double free in silc_server_command_leave in the file
5691 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Fixed the version checking in the server. Affected file is
5696 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Fixed the configuration data fetching when accepting new
5699 connections in the server. Affected file silcd/server.c.
5701 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Added `sender_entry' argument to the function
5704 silc_server_packet_relay_to_channel so that we can check
5705 whether some destination actually belongs to the same route
5706 the sender belongs (ie, we must not resend the packet to the
5707 sender). Affected file silcd/packet_send.[ch].
5709 * Added `servername' field to the SilcClientEntry in the server
5710 to hold the name of the server where client is from. Affected
5711 file is silcd/idlist.h.
5713 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Moved the channel message encrypting in the router betwen
5716 router connections from silc_server_channel_message to the
5717 silc_server_packet_relay_to_channel since we want to check
5718 whether we have anybody channel before encrypting anything.
5719 Affected files silcd/packet_[receive/send].c.
5721 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Fixed the [AdminConnection] server config section to support
5724 multiple entries. Affected file silcd/serverconfig.c.
5726 * Added support into the server to check the validity of the
5727 incoming connection before executing any KE or authentication
5730 * The connection configuration is now saved to the KE and
5731 connection auth protocol contexts and not fetched anymore in
5732 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5734 * The local hosts listenning address and port is also resolved
5735 now when starting the server. We want to have the socket object
5736 to include the real address and port for the listener. Added
5737 new function silc_net_check_local_by_sock into the files
5738 lib/silcutil/silcnet.[ch].
5740 * Fixed a broadcast bug in server -> do not broadcast if we
5743 * Fixed a routing bug. Do not route broadcast packets ever.
5744 Broadcast packets must be processed always and not routed since
5745 they may be destined to some other host than yourself and thus
5746 would get routed without no good reason. Affected file is
5749 * Added function silc_server_config_is_primary_route to check
5750 whether primary router connection has been configured (a router
5751 configuration that we are initiating). If there is not, we
5752 will assume that there is only two routers in the SILC network
5753 and we will use the incoming router connection as our primary
5754 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5756 * Changed the order of the broadcasting. Broadcast _after_ the
5757 packet has been processed not before. Affected file is
5760 * Fixed a [ClientConnection] parsing bug. The port was never
5761 parsed correctly thus resulting to port 0. Affected file
5762 silcd/serverconfig.c.
5764 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5765 argument and did not set the broadcast packet flag. Affected
5766 file silcd/packet_send.c. Fixed same bug in the function
5767 silc_server_send_notify as well.
5769 * If we receive NEW_ID packet for our own ID in the server, ignore
5772 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Removed the nickname from the Private Message Payload.
5777 Updated the code and the protocol specs.
5779 * Updated protocol specs for submitting to the IETF.
5781 * Tweaked the Random Number Generator a bit. Affected file
5782 lib/silccrypt/silcrng.c. Exported a new function
5783 silc_rng_[global]_add_noise which can be used to add more
5786 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Do not parse packets with different timeout when protocol
5789 is active -> may cause problem with rekey. Affected file
5792 * When server receives signoff notify it must not create
5793 new channel key if the client is on any channels since the
5794 sender of the signoff notify will create it.
5796 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Added printing of error messages during SKE protocol from the
5799 failure packet sent by server during SKE. Affected file
5802 * Removed the client's failure_callback handling with timeout
5803 and handle it immediately when received.
5805 * The SKE library returned wrong type in SUCCESS and FAILURE
5806 packets. They must be 32 bit MSB not 16 bit MSB.
5808 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Ok, rewrote the logic of the re-key and now it seems to work.
5811 I tested it on high traffic with frequent re-keys without
5812 problems. Added hmac_receive (and renamed hmac to hmac_send)
5813 in SilcClientConnection in lib/silcclient/client.h and
5814 in SilcIDListData in silcd/idlist.h. Also, removed the
5815 SilcPacketParserContext's cipher and hmac fields as they are
5816 not needed anymore and actually caused some problems when
5817 the ciphers and hmac's changed underneath the packet parser.
5819 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * If re-key protocol is active then process the incoming packets
5822 synchronously since we must assure that icoming packets encrypted
5823 with the old key is processed before the new keys is set to
5824 use. This is true other packets than for REKEY packets.
5825 Affected file silcd/server.c. The same was done to client library
5826 as well, affected file lib/silcclient/client.c.
5828 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Fixed bug in client and server to accept the force send if
5831 the packet is send from silc_[server/client]_packet_process
5832 function. Otherwise the packets are never delivered, oops.
5834 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Disable force sending of packets when REKEY protocol is active.
5837 We must assure that no packet is sent directly when rekey is
5838 performed. All packets must be sent through packet queue.
5839 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5840 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5841 function is silc_[server/client]_packet_send_real to check
5844 * Replaced the SIM paths from example config files to
5845 /usr/local/modules. Also, make install creates now
5846 /usr/local/silc/logs directory to hold all the SILC server
5849 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Made the configure.in.pre work on Solaris. Patch by salo.
5853 * Made all ciphers compatible with non-x86 machines. Defined
5854 CBC mode macros into lib/silccrypt/ciphers_def.h.
5856 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Fixed the make install.
5860 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * When MAC computation fails the silc_packet_decrypt returned 0
5863 even though it was supposed to return -1. Fixed this. The
5864 affected file is lib/silccore/silcpacket.c.
5866 * Do not replace the config files in /etc/silc (in make install)
5867 if they already exist. Affected file ./Makefile.am.
5869 * Do not send re-key packets immediately but through packet queue.
5870 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5872 * Changed silc_net_check_host_by_sock to return FALSE if the
5873 IP/DNS could not be resolved. Though, it returns the IP address
5874 now even if it could not resolve it (but returns also FALSE).
5875 Affected file lib/silcutil/silcnet.[ch].
5877 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added silc_pkcs_decode_identifier to decode the public key's
5880 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5881 Added also silc_pkcs_free_identifier. Added also new context
5882 SilcPublicKeyIdentifier.
5884 * Added -S option to the silc client. It is used to dump the
5885 contents of the specified public key file.
5887 * Changed the PKCS api to return the public key length when
5888 setting the public key.
5890 * Fixed a fatal bug in the public and private key file loading.
5891 Affected file lib/silccrypt/silcpkcs.c.
5893 * Execute the packet parsing for client with zero (0) timeout
5894 if the protocol is active. Affected file silcd/server.c.
5896 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Made the key generation options to the silcd program. Added
5899 -C option, equivalent to client's option.
5901 * Added new [ServerKeys] config section to the server. It
5902 configures the server's public and private key.
5904 * Defined generic Public Key Payload into the protocol
5905 specification to send specific type of public keys and
5908 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5909 public key or certificate.
5911 * Implemented the GETKEY command to the server and to the
5912 client library and on user interface.
5914 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Made preliminary `make install' work.
5918 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Added SilcServerRekey context into silcd/idlist.h.
5922 * Added the PFS support as defined in the specification to the
5923 SKE protocol. Affected files lib/silcske/*.c.
5925 * Added `ske_group' field to the SilcServerRekey context to hold
5926 the number of the SKE group that is used with PFS in re-key.
5927 Affected file silcd/idlist.h.
5929 * Added PFS re-key support to the server. Affected file is
5932 * Added silc_protocol_cancel to cancel execution of the next
5933 state of the protocol. Affected file is
5934 lib/silccore/silcprotocol.[ch].
5936 * Added the re-key support with and without PFS to the client
5937 library. Re-key is performed once in an hour, by default.
5939 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5940 Added silc_client_rekey_callback and silc_client_rekey_final.
5941 Affected files are lib/silcclient/protocol.[ch] and
5942 lib/silcclient/client.[ch].
5944 * Removed the `hmac_key' and `hmac_key_len' fields from the
5945 SilcClientConnection structure; not needed. Affected file is
5946 lib/silcclient/client.h.
5950 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Do not ask whether user wants to use the negotiated private key
5953 for private messages, just use it. Affected file is
5954 silc/local_command.c.
5956 * Added `send_enc_key' and `enc_key_len' fields to the
5957 SilcIDListData structure since they are needed in the re-key
5958 phase. Affected file is silcd/idlist.[ch].
5960 * Implemented the simple re-key protocol into the server.
5961 Affected files silcd/server.c and silcd/protocol.[ch]. The
5962 re-key will be performed once in an hour, by default.
5964 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5965 Added silc_server_rekey, silc_server_rekey_callback and
5966 silc_server_rekey_final.
5968 * Removed Tunneled flag from the protocol. Updated the code
5969 and the specifications.
5971 * Adde `pfs' field to the SilcIDListData to indicate whether
5972 the PFS is to be performed in the re-key. Affected file is
5975 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5978 int64 of at least the xintXX size. If void * is less that 4
5979 bytes uint32 * will be used. Defined bool as boolean.
5981 * Changed _ALL_ unsigned long and unsigned int to uint32,
5982 unsgined short to uint16 in the source tree.
5984 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5985 not handle clients that has entry->data.registered == FALSE.
5986 They are not in the network anymore. Affected file is
5989 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Implemented the sending of the SERVER_SIGNOFF notify in the
5992 server. Affected file is silcd/server.c.
5994 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5995 Added also silc_notify_payload_encode_args into the
5996 lib/silccore/silcnotify.[ch].
5998 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5999 Affected file silcd/packet_receive.c.
6001 * Implemented the SERVER_SIGNOFF notify handling in the client
6002 library. Affected file lib/silcclient/client_notify.c. Also,
6003 implemnted the printing of the SERVER_SIGNOFF info to the
6004 application. Affected file silc/client_ops.c.
6006 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6007 if the deleting was successful. Affected file silcd/idlist.[ch].
6009 * Added support for public key authentication in the connection
6010 authentication protocol in the client library. Affected file
6011 lib/silcclient/protocol.c.
6013 * Changed the server's silc_idlist_get_clients_by_* interface
6014 to support already allocated array so that new entries may be
6015 added to pre-allocated array. Affected file silcd/idlist.[ch].
6016 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6017 and command replies.
6019 * All command reply functions in the server now calls the
6020 pending command callback even if error occured. This way the
6021 error will be delivered to the client as well. Affected files
6022 silcd/command.c and silcd/command_reply.c.
6024 * Fixed INFO command to return local server's info if no server
6025 was provided. Affected file lib/silcclient/command.c.
6027 * Removed RESTART command for good. Updated the code and the
6030 * Rewrote parts of the task system. It is a bit simpler now.
6031 Removed unsued task priorities. The affected files are
6032 lib/silcutil/silctask.[ch].
6034 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Moved the USERS printing from the library to the application.
6037 Affected files lib/silcclient/command.c and silc/client_ops.c.
6039 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added channel key re-key support. The re-key is perfomed
6044 only by the router and is done once in an hour. Added `rekey'
6045 field to the SilcChannelEntry in the server. Affected files
6046 silcd/server.c and silcd/idlist.h.
6048 * Added silc_task_unregister_by_context into the file
6049 lib/silcutil/silctask.[ch].
6051 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added SILC_UMODE_GONE mode to indicate when the client is not
6054 present in the SILC network. Added also support to the local
6055 command AWAY that will set this mode. Added support of showing
6056 "xxx is gone" in WHOIS command. The USERS command shows the
6057 gone status as well.
6059 * Fixed setting server and router operator privileges in the
6060 server's UMODE command. Affected file silcd/command.c.
6062 * Merged the SKE KE1 and KE2 payloads into one payload. The
6063 new KE payload is equivalent to the old KE2 payload.
6065 Cleaned up the SKE Start Payload parsing. It now uses the
6066 simple buffer unformatting to do the parsing. A lot faster
6069 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6070 to the SKE that is used to indicate whether both of the SKE
6071 parties should perform authentication. By default only the
6072 responder performs authentication. By setting this flag also
6073 the initiator must do authentication. By default it is unset
6074 since in normal SKE case, client to server connection, only
6075 the responder should do authentication. When doing SKE between
6076 two clients both should perform authentication. Updated the
6077 code and the protocol specs.
6079 * A little fix to IDENTIFY command in the server. Search the
6080 client first by hash not nickname. Affected file is
6083 * Fixed the silc_client_close_connection to support closing
6084 the client to client connections wihtout deleting too much
6085 data. Affected file lib/silcclient/client.c.
6087 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6088 are received if protocol used to be active but is not anymore
6089 the application would crash due to NULL pointer dereference.
6090 Affected files silcd/server.c and lib/silcclient/client.c.
6092 * Added `hash' field to the SilcClientConnection to include
6093 the hash function negotiated in the SKE protocol.
6095 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6096 to set the channel founder authentication data. A client can
6097 claim the founder rights later by providing the authentication
6098 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6099 This way the channel founder can regain the channel founder
6100 privileges even it is left the channel. This works only on
6101 local server and the client must be connected to the same
6102 server to be able to regain the founder rights. Updated the
6103 protocol specs accordingly.
6105 Added support to the CMODE command in the client to set the
6106 founder auth data. Read the README to see how to set it.
6108 Added support to the CUMODE command to claim the founder
6109 rights. Read the README to see how to do it.
6111 Added support for the founder authentication to the Channel
6112 Entry in the server. Affected file silcd/idlist.h.
6114 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6115 server's CMODE command. Affected file silcd/command.c.
6117 * Added the following new functions into lib/silccore/silcauth.[ch]:
6118 silc_auth_get_method and silc_auth_get_data.
6120 * The server now saves the remote hosts public key to the
6121 SilcIDListData pointer. Affected file silcd/protocol.c.
6123 * The normal server now does not remove the channel entry from
6124 the cache if the founder authentication data is set. It used
6125 to remove it if the founder was the last one on the channel on
6126 the server and left the channel. The auth data is saved and
6127 if the channel is re-joined later the old entry is used with
6128 the old auth data. Affected files silcd/command_reply.c and
6131 * Removed the `pkcs' field from the SilcIDListData structure
6132 in the server; it is not used. Affected file silcd/idlist.h.
6134 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Fixed packet processing on slow links. Partial packets were
6137 never re-processed because the incoming data buffer was cleared
6138 by the application. Application must not directly clear the
6139 sock->inbuf, the packet processing routines handle it. Fixed
6140 this in client library and in server.
6142 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Fixed the WHOIS and IDENTIFY send reply function to really
6145 check whether to send list or just one entry. Affected file
6148 * Cleaned up the LEAVE command's channel key distribution. The
6149 affected file silcd/command.c.
6151 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6152 can enforce the channel mode as well. In that case the ID
6153 includes the ID of the server. The code now enforces the
6154 mode change if the router have different mode than the server.
6156 * The notify client operation with CMODE_CHANGE notify can now
6157 return NULL client_entry pointer if the CMODE was not changed
6158 by client. Application must check for this.
6160 * Added <Server ID> argument to INFO command to support server
6161 info fetching by Server ID.
6163 * Added silc_server_announce_get_channel_users to get assembled
6164 packets of channel users of the specified channel. Affected
6165 file silcd/server.[ch].
6167 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6168 was freed underneath the ID Cache.
6170 * Re-announce clients when the server received CHANNEL_CHANGE
6171 notify from the router. Affected file silcd/packet_send.c.
6173 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6176 crashed since it did not handle the fact that there is no cipher
6177 called "3" and didn't check the error condition. Now fixed.
6179 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6180 flag. It can be used to send message requests.
6182 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Implemented the RESTART command in the client.
6186 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6187 notice type messages. Added notice printing to the user
6190 * The channel keys are not re-generated if the channel's mode
6191 is PRIVKEY, ie private key on the channel exists. Affected
6192 files silcd/server.c and silcd/command.c.
6194 * Fixed a little bug in channel message delivery when channel
6195 private keys are set in the server. Affected file is
6196 silcd/packet_send.c.
6198 * Changed the setting on channel->on_channel = TRUE from the
6199 silc_client_save_channel_key to the JOIN command reply. The
6200 key payload is not received if the private channel key is set.
6201 Affected file lib/silcclient/command_reply.c and the
6202 lib/silcclient/client_channel.c.
6204 * When the CMODE_CHANGE notify is sent and the channel private
6205 key mode is removed the channel key must be re-generated in
6206 other cells as well. Added this support for the router in the
6207 silcd/packet_receive.c.
6209 * Added new local command NOTICE to send notice message on
6210 channel. Affected file silc/local_command.[ch].
6212 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Added new local command ME to the client. It is used to send
6215 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6216 some action. Affected file silc/local_command.[ch].
6218 * Changed channel_message and private_message client operations
6219 to deliver the message flags to the application. Added also
6220 the `flags' arguments to the silc_client_send_channel_message
6221 and silc_client_send_private_message functions. Affected file
6224 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Redefined the Private Message Payload to support private message
6227 keys and to support the new private message flags. Updated
6228 the protocol specs. Flags makes it possible to have for example
6229 CTCP style messages.
6231 * Added new type SilcPrivateMessagePayload and defined an API
6232 for it in the lib/silcclient/silcprivate.[ch].
6234 * Tested private message private keys successfully. Tested the
6235 private message key set, unset and list commands with the new
6238 * Redefined the Channel Message Payload to include the channel
6239 message flags (equal with private message flags) to support
6240 for example CTCP style messages.
6242 * Defined some of the message (for channel and private message)
6243 flags. Updated the protocol specs and added the flags to the
6244 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6246 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Added SilcKeyAgreementStatus type to the key agreement routines
6249 to indicate the current status and error if one occured.
6250 The status types are defined in the lib/silcclient/silcapi.h.
6252 * Added new local command KEY that is used to set and unset private
6253 keys for channels, set and unset private keys for private messages
6254 with remote clients and to send key agreement requests and
6255 negotiate the key agreement protocol with remote client. The
6256 key agreement is supported only to negotiate private message keys,
6257 it currently cannot be used to negotiate private keys for channels,
6258 as it is not convenient for that purpose.
6260 * Fixed a minor pending callback setting bug in the function
6261 silc_client_get_client_by_id_resolve, now the function works.
6262 Affected file lib/silcclient/idlist.c.
6264 * Added function silc_net_get_local_port to get local bound
6265 port by socket. Added to lib/silcutil/silcnet.[ch].
6267 * Added `sockets' and `sockets_count' fields to the SilcClient
6268 object. They hold the sockets of the listenning sockets in
6269 the client. Listenning sockets may be for example the key
6270 agreement server. Affected file lib/silcclient/client.[ch].
6271 Added functions the silc_client_add_socket and the
6272 silc_client_del_socket. They are exported to the application
6275 * Added ~./silc/clientkeys to support other client's public keys.
6277 * Renamed verify_server_key client operation to verify_public_key
6278 and added one argument to indicate the type of the connection
6279 (server, client etc.).
6281 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Added silc_server_connection_auth_request to handle the
6284 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6285 silcd/packet_receive.[ch].
6287 * Added silc_server_send_connection_auth_request into the
6288 silcd/packet_send.c to send the connection auth request packet.
6290 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6293 * Fixed the public key authentication in responder side in the
6294 server. The `auth_data' pointer includes the SilcPublicKey
6295 not the path to the public key. Affected file silcd/protocol.c.
6297 * Implemented the public key authentication in the initiator side
6298 in the server. Affected file silcd/protocol.c.
6300 * Removed the [RedirectClient] config section from the server
6301 configuration. Is not needed and I don't want to implement it.
6303 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Cleaned up the CMODE command in the server. It now works
6306 correctly and supports all the modes defined in the protocol.
6307 Affected file is silcd/command.c.
6309 * Added `hmac_name' field to the SilcChannelEntry in the server
6310 to hold the default HMAC of the channel. It can be set when
6311 creating the channel (with JOIN command). Affected files
6314 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6315 type to indicate the change of the current cipher and hmac
6316 on the channel. Client can safely ignore the <cipher> argument
6317 (if it chooses to do so) since the CHANNEL_KEY packet will
6318 force the channel key change anyway. The <hmac> argument is
6319 important since the client is responsible of setting the new
6320 HMAC and the hmac key into use.
6322 * Fixed the CMODE command in the client library as well.
6324 * Tested CMODE command in router environment successfully.
6326 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Show the version of the remote client (or server) when connecting
6329 to the server. It is logged to the log file. Affected file
6330 is silcd/protocol.c.
6332 * Fixed the KILLED notify handling in the client library. The
6333 client must be removed from all channels when receiving the
6336 Also, do not remove the client entry when giving the KILL
6337 command but when the KILLED notify is received.
6339 * Removed silc_idlist_find_client_by_nickname from the server.
6340 Not needed anymore. Affected files silcd/idlist.[ch].
6342 * Implemented the CHANNEL_CHANGE notify type handling to the
6343 server. Affected file silcd/server.c.
6347 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Added silc_server_send_notify_invite to send the INVITE
6350 notify between routers.
6352 * Implemented the INVITE command correctly to the server.
6354 * Implemented the INVITE notify type handling in the server.
6356 * Implemented the INVITE command to the client library and on the
6359 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Added function silc_server_get_client_resolve to find the
6362 client entry by ID from all ID lists and then resolve it
6363 (using WHOIS) if it cannot be found. Affected file is
6366 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Implemented the BAN command to the client library.
6370 * The JOIN command in the server now checks the invite list
6373 * Changed the silc_command_reply_payload_encode_va and the
6374 silc_command_payload_encode_va to support that if argument is
6375 NULL it ignores and checks the next argument. Affected file
6376 lib/silccore/silccommand.c.
6378 * Added silc_server_send_notify_ban to send the BAN notify
6379 type between routers.
6381 * Chaned the silc_notify_payload_encode to support that if
6382 argument is NULL it ignores and checks the next argument.
6383 Affected file lib/silccore/silcnotify.c.
6385 * Tested ban lists in router environment successfully.
6387 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Implemented BAN command to the server, in silcd/command.[ch].
6391 * Removed the BAN and INVITE_LIST modes from the CMODE command
6394 * Added function silc_string_match to regex match two strings.
6395 Affected files lib/silcutil/silcutil.[ch].
6397 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Redefined parts of the SilcChannelEntry in the server to support
6400 the new ban and invite lists.
6402 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Redefined the INVITE command. The same command can be used to
6405 invite individuals to the channel but also to manage the invite
6406 list of the channel (to add to and remove from the invite list).
6407 Updated the protocol specs.
6409 * Added new command SILC_COMMAND_BAN that can be used to manage
6410 the ban list of the channel. Updated the protocol specs.
6412 * Removed the channel modes: the SILC_CMODE_BAN and the
6413 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6414 in the CMODE command. The equivalent features are now available
6415 using INVITE and BAN commands. Updated the protocol specs.
6417 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6418 in the network about change in the current ban list. The notify
6419 type is not used by the client.
6421 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6422 support the invite lists.
6424 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Added new function silc_string_regexify that converts string
6427 including wildcard characters into regex string that can
6428 be used by the GNU regex library. Added into the file
6429 lib/silcutil/silcutil.[ch].
6431 Added silc_string_regex_combine to combine to regex strings
6432 into one so that they can be used as one regex string by
6433 the GNU regex library. Added into the file
6434 lib/silcutil/silcutil.[ch].
6436 Added silc_string_regex_match to match two strings. It returns
6437 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6439 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Imported GNU regex to the soruce tree into lib/contrib.
6442 Fixed some compiler warning from the regex.c.
6444 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Fixed MOTD command in the server to work in router environment.
6448 * Fixed the MOTD command in the client library to support
6449 the server argument in the command.
6451 * Added `nickname_len' argument to the silc_idlist_add_client
6452 in the server, as the `nickname' argument may be binary data
6455 * Added silc_idlist_get_channels to return all channels from
6458 * Implemented LIST command to the server. Affected file is
6461 * Implemented the LIST command to the client library and on the
6464 * Added [<user count>] argument to the LIST command reply.
6465 With private channels the user count is not shown.
6467 * Updated TODO and README.
6469 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6471 * The client entry's data.registered must be TRUE even with
6472 global client entry on global client list. The data.registered
6473 is used to check whether the client is anymore in the network,
6474 for example with WHOWAS command so it must be valid.
6476 * Fixed the WHOWAS command in the server. It now actually works
6477 in router environment. Added function into silcd/command_reply.c
6478 silc_server_command_reply_whowas_save.
6480 * Added silc_idlist_purge function to the silcd/idlist.c
6481 to periodically purge the ID Cache.
6483 * Fixed INFO command in the server. It works now in router
6484 environment. Added <server name> argument to the INFO command
6485 reply. Updated the protocol specs.
6487 * Fixed minor bug in silc_idcache_purge to not purge if the
6488 expire value is zero.
6490 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6491 they were buggy because of the WHOWAS information.
6493 * Fixed local command MSG to handle the async resolving of
6494 the remote client properly. It used to fail the first MSG.
6495 Affected file silc/local_command.c.
6497 * Added `data_len' field to SilcIDCache context.
6499 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Update TODO. Todo in commands in the server.
6503 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6506 used by routers as broadcast packet to inform other routers
6507 about the changed user mode.
6509 Implemented the notify handling in the server. Affected file is
6510 silcd/packet_receive.c. Added the function
6511 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6513 * Added new generic Channel Payload and deprecated the New Channel
6514 Payload. The New Channel Payload is now the generic Channel
6517 * Added new argument `mode' to the silc_server_send_new_channel
6518 as it is required in the Channel Payload now.
6520 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6521 and created a new and real SilChannelPayload to represent the
6522 new generic Channel Payload. Implemented the encode/decode
6523 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6525 * Added silc_server_get_client_channel_list to return the list
6526 of channels the client has joined for WHOIS command reply.
6527 Affected file silcd/server.[ch].
6529 * Implemented the channel list sending in the WHOIS command reply
6530 in server and in the client.
6532 Implemented the channel list displaying on the user interface
6533 as well. Affected file silc/client_ops.c.
6535 * Added silc_channel_payload_parse_list to parse list of Channel
6536 Payloads. It returns SilcDList list of SilcChannelPayloads.
6537 Client for example can use this function to parse the list of
6538 channels it receives in the WHOIS command reply. The caller
6539 must free the list by calling silc_channel_payload_list_free.
6540 Affected files lib/silccore/silcchannel.[ch].
6542 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Added one new argument <user mode> to the WHOIS command reply
6545 to return the mode of the user in SILC. Updated the protocol
6548 Implemented it to the server and client.
6550 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Fixed the mode printing on the user interface on joining.
6553 Affected file silc/client_ops.c.
6555 * Implemented the UMODE command and user modes in general to the
6556 client library and to the user interface.
6558 * Implemented the UMODE command to the server.
6560 * The server now sends UNKNOWN_COMMAND error status if client sends
6561 unknown command. Affected file silcd/command.c.
6563 * All server commands now handle the command identifier the right
6564 way when sending the command reply to the client. The client can
6565 use to identify the command replies with the identifier.
6567 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Added silc_server_get_client_route to resolve the route to
6570 the client indicated by the client ID. Affected file is
6573 * Added silc_server_relay_packet as general function to relay
6574 packet to arbitrary destination. This deprecates functions
6575 like _send_private_message_key, _relay_notify etc. Affected
6576 file is silcd/packet_send.[ch].
6578 Removed silc_server_send_key_agreement,
6579 silc_server_send_private_message_key and
6580 silc_server_packet_relay_notify functions from the file
6581 silcd/packet_send.[ch].
6585 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6586 server. Affected file silcd/packet_receive.[ch].
6588 * Implemented the KILL command to the client. Implemented the
6589 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6590 Affected files lib/silcclient/command[_reply].c and
6591 lib/silcclient/client_notify.c. Implemented the KILL notify
6592 printing in the user inteface.
6594 * Fixed a lot silc_parse_nick memory leaks from the client
6595 library in the file lib/silcclient/command.c.
6597 * Changed the silc_server_send_notify_on_channels's `sender'
6598 argument from SilcSocketConnection to SilcClientEntry to
6599 check the sender as entry and not as connection object and not
6600 to send to the client provided as argument. The affected file
6601 is silcd/packet_send.[ch].
6603 * The notify packets that are destined directly to the client used
6604 to not to be processed by the server. Now changed that and the
6605 server processes all notify packets. After relaying the packet
6606 to the client the notify packet is processed in the server.
6608 * The silc_server_free_client_data now checks whether there is
6609 pending outgoing traffic for the client and purges the data to
6610 the network before removing the client entry.
6612 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6615 an client is killed from the SILC Network. Updated the protocol
6618 Added new function silc_server_send_notify_killed to the
6619 silcd/packet_send.[ch].
6621 * Added function silc_server_packet_relay_notify to relay notify
6622 packets that are destined directly to a client. In this case
6623 the server does not process the notify packets but merely relays
6624 it to the client. Affected file silcd/packet_send.[ch].
6626 Added also silc_server_packet_process_relay_notify to check
6627 whereto relay the notify. Affected file is
6628 silcd/packet_receive.[ch].
6630 * Implemented the KILL command to the server.
6634 * Added the backup schema desgined last fall to the protocol
6635 specs for everyone to see. The specification is in the
6636 *-spec-xx.txt draft and the packet type definitions for the
6637 backup routers is in *-pp-xx.txt draft. Thusly, added also
6638 new packet type SILC_PACKET_CELL_ROUTERS.
6640 * A big security problem in the implementation discovered. The
6641 signoff of an client did not cause new channel key generation
6642 which it of course should've done. The channel keys must be
6643 always re-generated when client leaves (or signoffs) the channel.
6644 The silc_server_remove_from_channels funtion now handles
6645 the channel key re-generation.
6647 * Added `sender' argument to the silc_server_send_notify_on_channels
6648 to not to send the client provided as argument. Affected file
6649 silcd/packet_send.[ch].
6651 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Implemented OPER and SILCOPER commands into the server and
6656 * Added silc_auth_verify and silc_auth_verify_data to verify
6657 the authentication directly from the authentication payload.
6658 It supports verifying both passphrase and public key based
6659 authentication. Affected file lib/silccore/silcauth.[ch].
6661 * Added `hash' field to the SilcIDListData structure. It is the
6662 hash negotiated in the SKE protocol. Affected file is
6665 * Slight redesigning of the SilcAuthPayload handling routines.
6666 Do not send SilcPKCS but SilcPublicKey as argument.
6668 * Implemented the public key authentication support to the
6669 serverconfig. The public key is loaded from the provided path
6670 and saved as authentication data to void * pointer. Thus,
6671 changed the unsigned char *auth_data to void *auth_data;
6673 * Fixed SHUTDOWN command to send the reply before the server
6674 is shutdown. :) Affected file silcd/command.c.
6676 * Fixed fatal bug in CONNECT command. The hostname was invalid
6677 memory and server crashed. Affected file silcd/command.c.
6679 * Fixed fatal bug in CLOSE command. The server_entry became
6680 invalid but was referenced later in the command. Affected file
6683 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Fixed fatal bug in failure packet handling. Server ignored
6686 the failure and thus crashed when it came.
6690 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6693 that the command may be executed only once in (about) 2 seconds.
6694 The old SILC_CF_LAG flag is same but allows command bursts up
6695 to five before limiting.
6697 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6698 server code. Various commands now includes the CF_LAG_STRICT
6699 flag to disallow any kind of miss-use of the command.
6701 * Fixed the silc_buffer_unformat to not to allocate any data
6702 if the length of the data is zero. It used to allocate the
6703 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6705 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Changed the format of AdminConnection configuration section
6708 in the server. Added username of the admin to the format.
6709 Affected files silcd/serverconfig.[ch].
6711 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6712 to return admin configuration data by host, username and/or
6715 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Implemented WHOWAS command to the server. Added the functions:
6719 silc_server_command_whowas_parse,
6720 silc_server_command_whowas_send_reply,
6721 silc_server_command_whowas_from_client and
6722 silc_server_command_whowas_from_server
6724 * Added <Client ID> argument to the WHOWAS command reply. Updated
6725 the protocol specs accordingly.
6727 * Implemented WHOWAS command and command_reply to the client
6730 Implemented the WHOWAS printing on the user interface.
6732 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Added new argument to the WHOWAS command reply, the real name.
6735 It is an optional argument. Updated the protocol specs.
6737 * Added SilcIDCacheDestructor callback that is registered when
6738 the SilcIDCache is allocated. The callback is called when
6739 an cache entry in the ID Cache expires, or is purged from the
6740 cache. Added into lib/silccore/idcache.[ch].
6742 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6743 to destruct the client entries when the cache entry expires.
6744 Other ID Cache's in server and in the client library ignores
6747 * If the ID Cache entry's `expire' field is zero then the entry
6748 never expires. Added boolean `expire' argument to the
6749 silc_idcache_add function in the lib/silccore/idcache.[ch].
6750 If it is TRUE the default expiry value is used.
6752 * Added silc_server_free_client_data_timeout that is registered
6753 when client disconnects. By default for 5 minutes we preserve
6754 the client entry for history - for WHOWAS command.
6756 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Added support to the server to enforce that commands are not
6759 executed more than once in 2 seconds. If server receives
6760 commands from client more frequently, timeout is registered
6761 to process the commands. Affected file silcd/command.c.
6762 Added new function silc_server_command_process_timeout.
6764 * Changed NICK_NOTIFY handling in client library to check that
6765 if the client's nickname was changed, so there is no need to
6766 resolve anything from the server.
6768 * Removed error printing from the WHOIS and IDENTIFY commands.
6769 If error occurs then it is ignored silently in the client library.
6770 The application, however, may map the received error to
6771 human readable error string. The application currently maps
6772 the NO_SUCH_NICKNAME error to string.
6774 * Made the command status message public to the application. Moved
6775 them from lib/silcclient/command_reply.c to
6776 lib/silcclient/command_reply.h. The application can map the
6777 received command status to the string with the
6778 silc_client_command_status_message function.
6780 * Added check to the server to check that client's ID is same
6781 as the Source ID in the packet the client sent. They must
6784 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added dist-bzip hook to the Makefile.am to make bzip2
6787 compressed distributions.
6789 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Server now enforces the maximum length for the nickname and
6792 the channel as protocol specification dictates. 128 bytes for
6793 nickname and 256 bytes for channel name.
6795 * Moved the WHOIS printing to the application. The client libary
6796 does not print out the WHOIS information anymore, the application
6797 must do it. Renamed silc_client_command_reply_whois_print to
6798 the silc_client_command_reply_whois_save.
6800 The client's idle time is also sent to the application now, and
6801 the idle is shown on screen.
6803 * Added silc_client_command_reply_identify_save to save the
6804 received IDENTIFY entries.
6806 * Do not check for channel private keys in message sending and
6807 reception if the channel does not have the PRIVKEY mode set.
6808 Affected file lib/silclient/client_channel.c.
6810 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6813 just surfaced after chaning the JOIN procedure.
6815 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Added silc_client_get_clients_by_list to get client entries
6818 from Client ID list, that is returned for example by JOIN
6819 and USERS command replies. The application should use this
6820 function for example when JOIN command reply is received to
6821 resolve the clients already on the channel (library does not
6822 do that anymore as USERS command reply is not used in the JOIN
6823 procedure anymore). Affected files lib/silcclient/silcapi.h and
6824 lib/silcclient/idlist.c.
6826 * JOIN command reply and USERS command reply returns now SilcBuffer
6827 pointers instead of unsigned char pointers when returning
6828 the client list and mode list.
6830 * Added <Client ID> argument to the JOIN command reply, mainly
6831 for the server to identify for which client the command was
6832 originally sent. Updated protocol specs accordingly.
6834 * Added SilcDlist private_key pointer to the SilcChannelEntry
6835 in the client to support the channel private keys. Affected
6836 file is lib/silcclient/idlist.h.
6838 * Added SilcChannelPrivateKey argument to the function
6839 silc_client_send_channel_message so that application can choose
6840 to use specific private ke if it wants to. If it is not provided,
6841 the normal channel key is used, unless private keys are set.
6842 In this case the first (key that was added first) is used
6843 as the encryption key.
6845 * Implemented the support for channel private key handling.
6846 Implemented the following functions:
6848 silc_client_add_channel_private_key,
6849 silc_client_del_channel_private_keys,
6850 silc_client_del_channel_private_key,
6851 silc_client_list_channel_private_keys and
6852 silc_client_free_channel_private_keys
6854 Affected file lib/silcclient/client_channel.c.
6856 * Added the support for the private keys in the channel message
6857 sending and encryption and in the message reception and
6858 decryption. Affected funtions are
6859 silc_client_send_channel_message and silc_client_channel_message.
6861 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Added SKE's key verify callback to the client library's
6864 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6866 * Removed the statement that server (or router) must send USERS
6867 command reply when joining to the channel so that the client
6868 knows who are on the channel. Instead, the client list and
6869 client's mode list is now sent in the JOIN command reply to the
6870 client who joined channel. This is better solution.
6872 * Added function silc_server_get_users_on_channel and function
6873 silc_server_save_users_on_channel to the silcd/server.[ch].
6875 * Removed function silc_server_command_send_users from the
6878 * Do not show topic on the client library anymore. The topic is
6879 sent in the command reply notify to the application and the
6880 application must show the topic now.
6882 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6884 * Added client searching by nickname hash into the IDENTIFY and
6885 WHOIS commands in the server as they were clearly missing from
6886 them. Affected file is silcd/command.c.
6888 * Fixed a bug in private message receiving in the client library.
6889 The remote ID was freed and it wasn't supposed, now it is
6892 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Minor fix to the channel payload; allocate the data area, as it
6895 needs to be of specific length.
6897 * If the key agreement port is zero then the operating
6898 system will define the bound port. Affected files are
6899 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6901 * Added new function silc_channel_payload_decrypt into the file
6902 lib/silccore/silcchannel.[ch].
6904 * Moved the channel message etc, check from silc_packet_decrypt
6905 to applications. The library calls now a generic
6906 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6907 when the packet is either normal or special. This was done to
6908 allow more wide range of checking that was not allowed when
6909 the code was in library. Now applications can do virtually any
6910 checks to the packet and return to the library the decision how
6911 the packet should be processed. Affected files are
6912 lib/silccore/silcpacket.[ch].
6914 Added silc_server_packet_decrypt_check to the server and
6915 silc_client_packet_decrypt_check to the client library.
6917 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6918 to send with specified source and destination information.
6920 * Channel message delivery between routers was broken after the
6921 channel key distribution was fixed earlier. The channel key
6922 was used be to distributed to other routers as well which is not
6923 allowed by the protocol. Now this is fixed and channel keys
6924 really are cell specific and the channel message delivery between
6925 routers comply with the protocol specification.
6927 * Fixed various commands in server to check also the global list
6928 for the channel entry and not just the local list. The affected
6929 file silcd/command.c.
6931 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Added assert()s to buffer formatting and unformatting routines
6934 to assert (if --enable-debug) when error occurs. Affected
6935 file: lib/silcutil/silcbuffmt.c.
6937 * Changed to auto-reconnect to check whether the remote host is
6938 router and register the re-connect timeout if it is. It used
6939 to check that whether we are normal server, but router must do
6940 auto-reconnect with another router as well. Affected file
6943 * Removed the [<key len>] option from CMODE command as the cipher
6944 name decides the key length, nowadays. See the defined ciphers
6945 from the protocol specification.
6947 * Added [<hmac>] option to the CMODE command to define the HMAC
6948 for the channel. Added SILC_CMODE_HMAC channel mode.
6950 * Added [<hmac>] option for the JOIN command so that user can
6951 select which HMAC is used to compute the MACs of the channel
6954 * Added Hmac field to the Channel Message Payload. The integrity
6955 of plaintext channel messages are now protected by computing
6956 MAC of the message and attaching the MAC to the payload. The
6957 MAC is encrypted. Now, it is clear that this causes some
6958 overhead to the size of the packet but rationale for this is that
6959 now the receiver can verify whether the channel message decrypted
6960 correctly and also when private keys are set for the channel the
6961 receiver can decrypt the packet with several keys and check from
6962 the MAC which key decrypted the message correctly.
6964 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6965 lib/silccrypt/silccipher.[ch].
6967 * Added silc_hash_len to return the digest length into the
6968 lib/silcrypt/silchash.[ch].
6970 * Rewrote parts of Silc Channel Payload interface in the
6971 lib/silccore/silcchannel.[ch]. The encode function now also
6972 encrypts the packet and parse function decrypts it.
6974 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Fixed a minor formatting bug in the SKE's key material processing.
6977 It actually might have processed the keys wrong way resulting
6980 * Redefined the mandatory HMAC algorithms and added new algorithms.
6981 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6982 and hmac-md5 truncated to 96 bits. The mandatory is now
6983 hmac-sha1-96. Rest are optional (including the one that used
6984 to be mandatory). Rationale for this is that the truncated HMAC
6985 length is sufficient from security point of view and can actually
6986 make the attack against the HMAC harder. Also, the truncated
6987 HMAC causes less overhead to the packets. See the RFC2104 for
6990 * Added new [hmac] configuration section. The SKE used to use
6991 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6992 is of course wrong. The official names that must be proposed in
6993 the SKE are the ones defined in the protocol specification
6994 (hmac-sha1-96 for example). The user can configure any hmac
6995 using any hash function configured in the [hash] section. At
6996 least, the mandatory must be configured.
6998 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7000 * Added HMAC list to the SKE proposal list. It has now both
7001 hash algorithm list and HMAC list. This makes the protocol
7002 incompatible with previous versions. The SKE now seems to work
7003 the way it is supposed to work, for the first time actually.
7005 * Defined plain Hash algorithms to the protocol specification.
7008 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Implemented support for key agreement packets into the server.
7011 Added functions silc_server_key_agreement and
7012 silc_server_send_key_agreement. Other than these functions,
7013 server has nothing to do with this packet.
7015 * Added support for private message key packets into the server.
7016 Added functions silc_server_private_message_key and
7017 silc_server_send_private_message_key.
7021 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7022 called in the protocol's final callback instead in the END
7023 protocol state. This makes a little more sense and in the same
7024 time in client we can use the same protocol routines for normal
7025 key exchange and to key agreement packet handling as well.
7027 * Added to both client's and server's KE protocol context the
7028 SilcSKEKeyMaterial pointer to save the key material. We will
7029 bring the key material to the protocol's final callback by doing
7030 this. The final callback must free the key material.
7032 * Added SKE's packet_send callback into client's KE protocol
7033 context so that the caller can choose what packet sending function
7034 is used. This way we can use different packet sending when
7035 doing normal SKE when doing key agreement packet handling (in
7036 the key agreement packet handling we do not want to encrypt
7039 * Implemented the responder side of the key agreement routines
7040 in the client. The client can now bind to specified port and
7041 accept incoming key negotiation. The key material is passed
7042 to the application after the protocol is over.
7044 * Implemented the processing of incoming Key Agreement packet
7045 in the client. Added function silc_client_key_agreement to
7048 * Implemented the intiator side of the key agreement routines
7049 in the client. The client can now initiate key agreement with
7050 another remote client. The key material is passed to the
7051 application after the protocol is over.
7053 * Created client_keyagr.c to include all the key agreement
7056 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7057 SILC_TASK_CALLBACK except that it is not static.
7059 * Created client_notify.c and moved the Notify packet handling
7060 from the client.[ch] into that file.
7062 * Created client_prvmsg.c and moved all private message and
7063 private message key routines from the client.[ch] into that file.
7065 * Create client_channel.c and moved all channel message and
7066 channel private key routines from the client.[ch] into that file.
7068 * Changed silc_client_get_client_by_id_resolve to resolve with
7069 WHOIS command instead of IDENTIFY command, in the file
7070 lib/silclient/idlist.c.
7072 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Implemented the SKE's responder side to the Client library.
7076 * When FAILURE is received to the protocol do not trust it
7077 blindly. Register a timeout to wait whether the remote closes
7078 the connection as it should do it, only after that process the
7079 actual failure. This was changed to both client and server.
7081 * Added client_internal.h to include some of the structures
7082 there instead of client.h in lib/silcclient/.
7084 * Added function silc_task_unregister_by_callback to unregister
7085 timeouts by the callback function.
7087 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Some "Incomplete WHOIS info" errors has been appearing on the
7090 log files. Took away the entry->userinfo check from WHOIS
7091 reply sending. The entry->userinfo is now " " if client did not
7092 provide one. I thought this was fixed earlier but something
7093 is wrong still. Let's see if the error still appears.
7095 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Fixed a minor bug in the login when the channel key is
7098 re-generated in the server. It used to generate the key in
7099 wrong order and thus caused problems in the channel traffic.
7101 * Fixed a minor bug in channel key distsribution after
7102 KICK command. The key was not sent to the router even though
7105 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Added silc_ske_process_key_material_data as generic routine
7108 to process any key material as the SILC protocol dictates. The
7109 function is used by the actual SKE library but can be used by
7110 applications as well. This relates to the private message keys
7111 and the channel private keys since they must be processed the
7112 same way the normal SILC session keys. The protocol dictates
7113 this. Affected files: lib/silcske/silcske.[ch].
7115 Added also silc_ske_free_key_material to free the
7116 SilcSKEKeyMaterial structure.
7118 * Defined silc_cipher_set_key function to set the key for
7119 cipher without using the object's method function. The affected
7120 files: lib/silccrypt/silccipher.[ch].
7122 * Implemented silc silc_client_add_private_message_key,
7123 silc_client_add_private_message_key_ske,
7124 silc_client_del_private_message_key,
7125 silc_client_list_private_message_keys and
7126 silc_client_free_private_message_keys functions in the
7129 Added functions silc_client_send_private_message_key to send
7130 the Private Message Key payload and silc_client_private_message_key
7131 to handle incoming Private Message Key payload.
7133 * Added Cipher field to the Private Message Key payload to set
7134 the cipher to be used. If ignored, the default cipher defined
7135 in the SILC protocol (aes-256-cbc) is used.
7137 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Removed lib/silcclient/ops.h file.
7141 Redefined parts of the SILC Client Library API. Created new
7142 file silcapi.h that deprecates the ops.h file and defines the
7143 published Client Library API. Defined also private message key
7144 API and channel private key API into the file.
7146 This is the file that the application must include from the
7147 SILC Client Library. Other files need not be included by
7148 the application anymore.
7150 * Added new key_agreement client operation callback and also
7151 defined the Key Agreement library API for the application.
7153 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7156 is used by clients to request key negotiation between another
7157 client in the SILC network. If the negotiation is started it
7158 is performed using the SKE protocol. The result of the
7159 negotiation, the secret key material, can be used for example
7160 as private message key.
7162 Implemented the Key Agreement payload into the files
7163 lib/silccore/silauth.[ch].
7165 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Redefined ciphers for the SILC protocol. Added some new ciphers
7168 and defined the key lengths for the algorithms. Changed the
7169 code accordingly. The default key length is now 256 bits.
7171 * Fixed SKE key distribution function silc_ske_process_key_material
7172 when the key length is more than 128 bits. The default key
7173 length in SILC is now 256 bits.
7175 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7176 to indicate unsupported algorithm.
7178 * Renamed rijndael.c to aes.c and all functions as well.
7180 * Fixed a long standing channel key setting bug in client library.
7181 Weird that it has never surfaced before.
7183 * Fixed bug in channel deletion. If the entire channel is removed
7184 then it must also delete the references of the channel entry
7185 from the client's channel list as the client's channel entry and
7186 the channel's client entry share same memory.
7188 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Implemented CONNECT and SHUTDOWN commands in the client.
7192 * Implemented CLOSE command to the client.
7194 * Added the function silc_idlist_find_server_by_name into the
7195 files silcd/idlist.[ch].
7197 Added the function silc_idlist_find_server_by_conn into the
7198 files silcd/idlist.[ch].
7200 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * DIE command was renamed to SHUTDOWN. Updated the both code
7205 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7206 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7208 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7211 * Added function silc_server_create_connection function to create
7212 connection to remote router. My server implementation actually
7213 does not allow router to connect to normal server (it expects
7214 that normal server always initiates the connection to the router)
7215 so the CONNECT command is only good for connecting to another
7218 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7221 or some other client was kicked from the channel.
7223 Implemented the handling of the notify type to both client
7226 Implemented silc_server_send_notify_kicked to send the KICKED
7227 notify. It is used to send it to the server's primary router.
7229 * Implemented the KICK command into server and client.
7231 * Added `query' argument to the silc_idlist_get_client function
7232 to indicate whether to query the client from server or not if
7235 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7236 to indicate that the client is not channel founder.
7240 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Removed the rng context from SilcPacketContext structure and
7243 changed that the packet routine uses the Global RNG API.
7245 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * Added support for quit message that client can "leave" on the
7248 channel when it quits the SILC. It is ditributed inside the
7249 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7251 Added silc_server_free_client_data that will take the
7252 signoff message as argument.
7254 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7256 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7258 * Updated parts of the protocol specification to keep it up
7261 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7264 payloads in one packet.
7266 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7267 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7268 use now the new List flag.
7270 * Also deprecated the following packet types: REPLACE_ID,
7271 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7273 * Added list support for Notify packet in server.
7275 * Added silc_server_send_notify_channel_change to send the
7276 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7277 the silc_server_send_replace_id.
7279 * Added silc_server_send_notify_nick_change to send the
7280 NICK_CHANGE notify type. Deprecates the function
7281 silc_server_send_replace_id.
7283 * Added silc_server_send_notify_join to send the JOIN notify type.
7284 Deprecates the function silc_server_send_new_channel_user.
7286 * Added silc_server_send_notify_leave to send LEAVE notify type.
7287 Deprecates the function silc_server_send_remove_channel_user.
7289 * Added silc_server_send_notify_cmode and
7290 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7291 types. Deprecates the silc_server_send_set_mode function.
7293 * Added SERVER_SIGNOFF notify type to indicate that server has
7294 quit. This means that all clients on the channel from that
7295 server will drop. This can be also used when netsplit happens.
7297 Deprecated REMOVE_ID packet type since it is not needed anymore
7300 Added silc_server_send_notify_server_signoff to send the
7301 SERVER_SIGNOFF notify type. Deprecates the function
7302 silc_server_send_remove_id.
7304 Added also silc_server_send_notify_signoff to send the
7305 SIGNOFF notify type.
7307 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7308 SILC protocol from this day on. Changed the protocol
7309 specification as well.
7311 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7312 notify type. It is used between routers to notify about
7313 topic changes on a channel.
7315 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7318 * Partly updated the protocol specification to comply with the
7319 changes now made. It is still though a bit outdated.
7321 * The JOIN notify type now takes one extra argument <Channel ID>.
7322 The packet used to be destined to the channel but now the
7323 JOIN type may be sent as list thus it is impossible to
7324 destine it to any specific channel. By adding this argument
7325 it is again possible.
7327 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7329 * Added CREDITS file. The CHANGES and CREDITS file will appear
7330 in the distribution as well.
7332 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7335 types in the server's silcd/packet_receive.c.
7337 * Implemented CMODE and CUMODE to work in router environment.
7339 * Fixed minor encoding and decoding buglet from the
7340 lib/silccore/silcmode.c.
7342 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7345 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7347 * Changed all SilcConfigServer* and silc_config_server* to
7348 SilcServerConfig* and silc_server_config*, respectively.
7351 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7353 * Associated the ID (client or server ID) to the Authentication
7354 Payload to avoid any possibility of forging. Updated the
7355 protocol specification and the code accordingly.
7357 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * The RSA key length is now save to the RsaKey context in the
7360 key generation process in lib/silccrypt/rsa.c. The key length
7361 is now used to figure out the maximum size of the block allowed
7362 to be encrypted/signed.
7364 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7365 is equivalent to the silc_mp_mp2bin but does not allocate any
7368 * Changed silc_mp_mp2bin API to take length argument. If it is
7369 non-zero then the buffer is allocated that large. If zero, then
7370 the size is approximated using silc_mp_sizeinbase, which however
7373 * Created Global RNG API which is global RNG that application can
7374 initialize. After initializing, any routine anywhere in the
7375 code (including library) can use RNG without allocating a new
7376 RNG object. This was done to allow this sort of use of the
7377 RNG in code that has no chance to allocate RNG object. All
7378 applications currently allocate this and many routines in the
7379 library use this. Affected file lib/silccrypt/silcrng.[ch].
7381 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7382 it to use the Global RNG API.
7384 * Defined Authentication Payload into protocol specification that
7385 is used during SILC session to authenticate entities. It is
7386 used for example by client to authenticate itself to the server
7387 to obtain server operator privileges.
7389 Implemented this payload into the lib/silccore/silcauth.[ch].
7390 Implemented also routines for public key based authentication
7391 as the new protocol specification dictates.
7393 Moved definitions of different authentication methods from
7394 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7396 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7397 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7398 silc_pkcs_verify_with_hash functions into the file
7399 lib/silccrypt/silcpkcs.[ch].
7401 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * The client entry's userinfo pointer must be always valid.
7404 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7405 will fail since it requires the userinfo. Now, the userinfo
7406 is allocated as "" if actual userinfo does not exist. Actually,
7407 it must exist and it is totally Ok to drop client connections
7408 that does not announce the userinfo. However, we will make
7409 this workaround for now.
7411 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7412 to return the remote port by socket.
7414 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7417 SILC_SERVER_PENDING_EXEC and added an new macro
7418 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7419 data or when error occurs while processing the pending command.
7421 Added new argument `destructor' into silc_server_command_pending
7422 and to the SilcServerCommandPending object. This destructor is
7423 now called after calling the pending callback or if error occurs
7424 immediately. If error occurs the actual pending callback won't
7425 be called at all - only the destructor. The destructor may be
7426 NULL if destructor is not needed.
7428 All this applies for client library code as well. Similar
7429 changes were made there as well for the pending commands.
7431 In the client, the application must now allocate the
7432 SilcClientCommandContext with the silc_client_command_alloc
7435 * Added reference counter to the SilcServerCommandContext. Added
7436 function silc_server_command_alloc and silc_server_command_dup
7439 Same type of functions added to the client library for the same
7442 * Removed the cmd_ident from IDListData away since it is now
7443 global for all connections. It is the command identifier used
7444 in command sending and with pending commands. The affected file
7447 * Added reference counter to the SilcSocketConnection objecet to
7448 indicate the usage count of the object. The object won't be
7449 freed untill the reference counter hits zero. Currently only
7450 server uses this, and client ignores it. The client must be
7451 set to use this too later. The affected files are
7452 lib/silccore/silcsockconn.[ch]. Added also the function
7453 silc_socket_dup to increase the reference counter.
7455 This was mainly added because it is possible that the socket
7456 is removed underneath of pending command or other async
7457 operation. Now it won't be free'd and proper DISCONNECTING
7458 flags, etc. can be set to avoid sending data to connection that
7459 is not valid anymore.
7461 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7462 the connection. After that it sets SILC_SET_DISCONNECTED.
7463 It is, however, possible that the socket data is not still freed.
7464 The silc_server_packet_process now checks that data is not
7465 read or written to connection that is DISCONNECTED. The socket
7466 get's freed when the reference counter hits zero.
7468 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7470 * Changed the client operation API: channel_message operation's
7471 `sender' is now the client entry of the sender, not the nickname
7472 and the `channel' is the channel entry, not the channel name.
7474 In the private_message operation the `sender' is now also the
7475 client entry of the sender not the nickname.
7477 Affected file is lib/silcclient/ops.h and all applications
7478 using the client operations.
7480 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7482 * Moved the calling of ops->connect() from connect_to_server_final
7483 into receive_new_id functin since that is the point when the
7484 client is actually allowed to send traffic to network. The
7485 affected file is lib/silcclient/client.c.
7487 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7490 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7491 (if needs broadcasting) instead of broadcasting the packets one
7492 by one which would make a burst in the network traffic.
7494 * Added `broadcast' argument to the functions in silcd/server.[ch]
7495 silc_server_create_new_channel[_with_id] to indicate whether
7496 to send New Channel packet to primary router.
7498 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Added new function into the silcd/server.[ch] files:
7501 silc_server_create_new_channel_with_id to create new channel with
7502 already existing Channel ID.
7504 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7505 lib/silccore/silcpacket.h. This packet is used t send list of
7506 Set Mode payloads inside one packet. Server uses this to set
7507 the modes for the channels and clients on those channels, that it
7508 announced to the router when it connected to it. The protocol
7509 specification has been updated accordingly.
7511 * The silc_server_new_channel did not handle the packet coming
7512 from normal server as it normally does not send that. However,
7513 when it announces its channels it does send it. Implemented
7514 the support for that.
7516 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7517 into the file lib/silccore/id.h.
7519 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Fixed memory leaks in the functions silc_idlist_del_client,
7522 silc_idlist_del_channel and silc_idlist_del_server in the file
7523 silcd/idlist.c. All of those leaked like a sieve.
7525 * Fixed some small memory leaks in the client's function
7526 silc_client_notify_by_server.
7528 * Added functions into silcd/server.c: silc_server_announce_clients,
7529 silc_server_announce_channels and silc_server_announce_server.
7530 These functions are used by normal and router server to announce
7531 to its primary router about clients, channels and servers (when
7532 router) that we own. This is done after we've connected to the
7535 These functions effectively implements the following packet types:
7536 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7537 and SILC_PACKET_NEW_ID_LIST.
7539 * Added new functions into the silcd/packet_receive.[ch]:
7540 silc_server_new_id_list, silc_server_new_channel_list and
7541 silc_server_new_channel_user_list to handle the incoming
7542 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7544 * Added support of changing Channel ID in the function
7545 silc_server_replace_id. If the server that announces a channel
7546 to the router already exists in the router (with same name but
7547 with different Channel ID), router is responsible to send
7548 Replace ID packet to the server and force the server to change
7549 the Channel ID to the one router has.
7551 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7552 client that the Channel ID has been changed by the router. The
7553 normal server sends this to the client. Client must start using
7554 the new Channel ID as the channel's ID.
7556 Implemented handling of this new type into lib/silcclient/client.c
7557 into the function silc_client_notify_by_server.
7559 * Added new function silc_idlist_replace_channel_id into the files
7560 silcd/idlist.[ch] to replace the Channel ID.
7562 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7564 * Call silc_server_command_identify_check always when processing
7565 the IDENTIFY command in silcd/command.c
7567 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7569 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7570 send keepalive packets. The packet can be sent by clients,
7571 servers and routers.
7573 Added function silc_socket_set_heartbeat into the file
7574 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7575 If not set, the heartbeat is not performed. The actual
7576 heartbeat is implemented in the low level socket connection
7577 library. However, application is responsible of actually
7580 Added silc_server_send_heartbeat to send the actual heartbeat
7581 packet into silcd/packet_send.[ch]. Server now performs
7582 keepalive with all connections.
7584 * Added silc_task_get_first function into lib/silcutil/silctask.c
7585 to return the timeout task with shortest timeout. There was a bug
7586 in task unregistration that caused problems. TODO has been
7587 updated to include that task system must be rewritten.
7589 * The client library will now resolve the client information when
7590 receiving JOIN notify from server for client that we know but
7591 have incomplete information.
7593 * Rewrote parts of silc_server_remove_from_channels and
7594 silc_server_remove_from_one_channel as they did not remove the
7595 channel in some circumstances even though they should've.
7597 * Encryption problem encountered in server:
7599 The LEAVE command used to send the Channel Key packet to the
7600 router immediately after generating it. However, the code
7601 had earlier sent Remove Channel user packet but not immediately,
7602 ie. it was put to queue. The order of packets in the router
7603 was that Channel Key packet was first and Remove Channel User
7604 packet was second, even though they were encrypted in the
7605 reverse order. For this reason, MAC check failed. Now, this
7606 is fixed by not sending the Channel Key packet immediately but
7607 putting it to queue. However, this is more fundamental problem:
7608 packets that are in queue should actually not be encrypted
7609 because packets that are sent immediately gets encrypted
7610 actually with wrong IV (and thus MAC check fails). So, packets
7611 that are in queue should be encrypted when they are sent to
7612 the wire and not when they put to the queue.
7614 However, the problem is that the current system has not been
7615 designed to work that way. Instead, the packet is encrypted
7616 as soon as possible and left to the queue. The queue is then
7617 just purged into wire. There won't be any fixes for this
7618 any time soon. So, the current semantic for packet sending
7621 o If you send packet to remote host and do not force the send
7622 (the packet will be in queue) then all subsequent packets to the
7623 same remote host must also be put to the queue. Only after the
7624 queue has been purged is it safe again to force the packet
7627 o If you send all packets immediately then it safe to send
7628 any of subsequent packets through the queue, however, after
7629 the first packet is put to queue then any subsequent packets
7630 must also be put to the queue.
7632 Follow these rules and everything works fine.
7634 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Added new function silc_server_remove_clients_by_server to
7637 remove all client entries from ID list when the server connection
7638 is lost. In this case it is also important to invalidate all
7639 client entires as they hold the invalid server entry. This
7640 fixes fatal bug when server has lost connection and will reconnect
7643 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Made some sanity checks to silc_server_daemonise like to check
7646 whether the requested user and group actually exists.
7648 * Added sanity check to SKE's silc_ske_responder_finish to check
7649 that the public and private key actually is valid.
7651 * Invalidate the client's nickname when receiving Replace ID
7652 packet and the Client ID is being replaced. This means that the
7653 server will query the nickname if someone needs it (client)
7656 * Sort the ID Cache in client library when the ID Cache data
7657 has changed (needs sorting).
7659 * Do not allow for SILC client to create several connections to
7660 several servers. The client does not support windows right now
7661 and generating multiple connections causes weird behaviour.
7663 Irssi-silc client does support windows and can handle several
7664 connections without problems, see: www.irssi.org and SILC plugin.
7666 * Fixed some places where client was added to the IDList. The
7667 rule of thumb is following (in order to get everything right):
7668 If the client is directly connected local client then the
7669 `connection' argument must be set and `router' argument must be
7670 NULL to silc_idlist_add_client function. If the client is not
7671 directly connected client then the `router' argument must
7672 bet set and the `connection' argument must be NULL to the
7673 silc_idlist_add_client function.
7675 * The funtion silc_server_packet_send_local_channel actually did
7676 not check whether the client was locally connected or not. It
7677 does that now. Fixed a bug related to LEAVE command.
7679 * Fixed Remove Channel User payload parsing bug in server's
7680 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7682 * The server's silc_server_save_channel_key now checks also the
7683 global ID list for the channel as it might not be in the local
7684 list. Fixed a bug related to LEAVE command.
7686 * Is this the end of the [<unknown>] buglet that has been lurking
7687 around for a long time? A little for loop fix in server's
7688 silc_server_command_whois_parse that is used by both IDENTIFY
7689 and WHOIS command. At least, this was a clear bug and a cause
7690 of one type of [<unknown>] buglet.
7692 * WHOIS and IDENTIFY commands call the function
7693 silc_server_command_[whois/identify]_check function even if
7694 we are not router server.
7696 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * Added --with-gmp configuration option. If set the GMP
7699 is always compiled in the SILC source tree. If not set then
7700 it is checked whether the system has the GMP3 installed. If
7701 it has then the GMP won't be compiled (the system's headers
7702 and library is used), if it doesn't have it then the GMP is
7703 compiled in the SILC source tree.
7705 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Changed RSA private exponent generation to what PKCS #1
7708 suggests. We try to find the smallest possible d by doing
7709 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7710 not security fix but optimization.
7712 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Added new config entry [Identity] to fork the server and run
7715 it as specific user and group. A patch from Bostik.
7717 * Imported Dotconf configuration library into lib/dotconf.
7718 This will be used to create the SILC configuration files later.
7719 It will appear in the distsribution after this commit.
7721 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * A big code auditing weekend happening. Auditing code for
7724 obvious mistakes, bugs and errors. Also, removing any code
7727 Removed files for being obsolete:
7729 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7730 inline in the file lib/silcutil/silcbuffer.h)
7732 o lib/silcutil/silcbufutil.c (the header has inline versions)
7734 Changed code to fix possible error conditions:
7736 o The buffer formatting routines now check that the destination
7737 buffer really has enough space to add the data. This applies for
7738 both buffer formatting and unformatting
7739 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7740 unformatting was changed to accomodate following rules:
7741 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7742 sent to the function while XXX_*STRING will not allocate or copy
7743 the data into the buffer. Instead it sets the pointer from the
7744 buffer into the pointer sent as argument (XXX_*STRING used to
7745 require that the pointer must be allocated already). This change
7746 makes this whole thing a bit more consistent and more optimized
7747 (note that the data returned in the unformatting with XXX_*STRING
7748 must not be freed now). The routines return now -1 on error.
7750 o Tried to find all code that use buffer_format and buffer_unformat
7751 and added return value checking to prevent formatting and
7752 especially unformatting errors and possible subsequent fatal
7755 o Changed ske->x and ske->KEY to mallocated pointers in
7756 lib/silcske/silcske.h. Fixed possible data and memory leak.
7758 o Added return value checking to all *_parse* functions. Fixed
7759 many memory leaks as well.
7761 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7762 so that buffer overflows would not happen. All code now also
7763 checks the return value as it can fail.
7765 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7767 * Added reconnection support to server if the normal server looses
7768 its connection to the router (for example if router is rebooted).
7769 The server performs normal reconnection strategy implemented
7770 to the server. Affected file silcd/server.c.
7772 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7774 * Added new packet type SILC_PACKET_SET_MODE that is used to
7775 distribute the information about changed modes (for clients,
7776 channels and clients channel modes) to all routers in the
7777 network. Updated the protocol specification accordingly.
7779 Added functions into silcd/packet_send.c and
7780 silcd/packet_receive.c: silc_server_send_set_mode,
7781 silc_server_set_mode.
7783 Added new files silcmode.[ch] into lib/silccore that implements
7784 the encoding and decoding of Set Mode Payload. Added new type
7785 SilcSetModePayload. Moved the definitions of different modes
7786 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7788 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7790 * Oops, a little mistake in server's connection authentication
7791 protocol. The protocol is not ended with FAILURE but with
7792 SUCCESS if the authentication is Ok. :) Affected file is
7795 * Implemented NICK_CHANGE notify handling in server in the file
7796 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7797 the local clients on the channel. After the changing nickname
7798 in router environment snhould work and the [<unknown>] nickname
7799 should appear no more.
7801 The silc_server_replace_id function that receives the Replace ID
7802 payload now sends the NICK_CHANGE notify type also in the file
7803 silcd/packet_receive.c
7805 * Changed WHOIS and IDENTIFY command to support the maximum amount
7806 of arguments defined in protocol specs (3328 arguments). This
7807 fixed a bug that caused problems when there were more than three
7810 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Added extra parameter, command identifier, to the
7813 silc_client_send_command so that explicit command identifier
7816 Changed that ID list routines uses specific command identifier
7817 when sending WHOIS/IDENTIFY requests to the server so that they
7818 can be identified when the reply comes back.
7820 Affected files lib/silcclient/command.[ch],
7821 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7823 * Added `sender' argument to silc_server_packet_send_to_channel
7824 to indicaet the sender who originally sent the packet to us
7825 that we are now re-sending. Ignored if NULL. Affected file
7826 silcd/packet_send.[ch].
7828 * Added some server statistics support in silcd/server_internal.h
7829 SilcServerStatistics structure and around the server code. Also
7830 send some nice statistics information when client is connecting
7833 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Fixed channel ID decoding in server's JOIN command reply in
7836 silcd/command_reply.c
7838 * Fixed braodcasting of replace ID payload to not to send it if
7839 we are standalone server in silcd/packet_receive.c.
7841 * Fixed all channel message sending routines to not to send
7842 packets to clients that has router set, since they are routed
7843 separately in the same function earlier. Affects file
7844 silcd/packet_send.c and all channel packet sending functions.
7846 * In USERS reply, res_argv[i] are not allocated, the table
7847 is allocated. Thus changed that free the table, not its
7850 * In server's whois_check and identify_check if the client is
7851 locally connected do not send any WHOIS commands - they are not
7854 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Fixed some minor bugs in client when sending WHOIS command. The
7857 arguments was in wrong order.
7859 * Removed statis function add_to_channel from server in
7860 silcd/command.c that was previously used with the joining but
7863 * Tested USERS command in router environment successfully with two
7864 routers, two servers and two clients.
7866 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Reorganized the USERS command and command reply in client library
7869 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7870 When the command is given by user we register a pending command
7871 callback that will reprocess the command after the reply has been
7872 received from the server. When reprocessing the packet we then
7873 display the information. Thus, the USERS information is displayed
7874 now in the command callback instead of in the command reply
7875 callback. The processing of the command is same as previously
7876 when server has sent the command reply in the JOINing process.
7878 * Added to USERS command in silcd/command_reply.c to join the client,
7879 we didn't use to know about, to the channel after we've created
7880 a client entry for it. Also, for clienet we did know already still
7881 check whether it is on the channel or not and add it if not.
7883 * Removed silc_server_command_join_notify as the function and its
7886 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7888 * Changed the client's pending command handling to the same as the
7889 server's pending command handling. It is also now possible to
7890 execute command reply functions from other command reply
7891 function as the function callbacks for commands and command
7892 replies are one and same. The pending commands are not static
7893 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7894 in client connection context. Thus, pending commands are server
7895 connection specific as it is convenient.
7897 Changed the function silc_client_command_pending and
7898 silc_client_command_pending_del and added new function
7899 silc_client_command_pending_check. Removed the
7900 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7903 * Added cmd_ident, current command identifier, to the client
7904 connection context in lib/silcclient/client.h to keep track on
7905 command identifiers used in command sending. Client's command reply
7906 function handling now supports the mandatory command identifiers.
7908 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7909 funtions in client to fully support pending command callbacks.
7911 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7912 as one of the arguments to the application in the command reply
7915 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7916 before first releasing SILC but came back. Now it is removed again
7917 and should come back nomore. The FORWARDED flag was used only
7918 by the JOINing procedure by forwarding the command packet to router.
7919 Now, the JOINing procedure has been changed to more generic (due
7920 to various router environment issues) and FORWARDED is not needed
7921 anymore for anything. The protocol specification is yet to be
7924 Now, removed silc_server_packet_forward from server and the flag
7925 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7927 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Renamed NAMES command to USERS command. The NAMES was named that
7930 due to historical reasons. Now it is renamed. Also, rewrote
7931 parts of the USERS command. The nickname list is not sent anymore
7932 by the server. Only Client ID and mode lists are sent in the USERS
7933 command. Changed this also to the protocol specification.
7935 The client now resolves the names and stuff after it receives
7936 the USERS list from the server when joining to the channel.
7938 * WHOIS and IDENTIFY commands has been changed to support multiple
7939 Client ID's per command. One can now search for multiple users
7940 in the network by sending only one WHOIS or IDENTIFY command.
7941 Changed the code and the protocol specifications.
7943 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7944 uses silc_server_command_whois_parse to parse the request. */
7946 * If normal server, do not parse the WHOIS and IDENTIFY requests
7947 before sending it to the router. Saves some time.
7949 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7951 * Fixed JOIN command on client library. Wrong number of arguments
7952 used to crash the client.
7954 * Added silc_server_channel_has_global function to check whether
7955 channel has global users or not.
7957 * Added silc_server_channel_has_local function to check whether channel
7958 has locally connected clients on the channel.
7960 * The silc_server_remove_from_one_channel now checks whether the
7961 channel has global users or not after given client was removed from
7962 the channel. It also checks whether the channel has local clients
7963 on the channel anymore. If it does not have then the channel entry
7964 is removed as it is not needed anymore.
7966 * The silc_server_notify now checks on JOIN notify whether the joining
7967 client is one of locally connected or global. If it is global then
7968 the channel has now global users on the channel and that is marked
7969 to the channel entry. Also, it now saves the global client to
7970 global list who is joining and JOINs it to the channel. This is
7971 for normal server, that is.
7973 Changed silc_server_send_notify_on_channel,
7974 silc_server_packet_relay_to_channel and
7975 silc_server_packet_send_to_channel check if we are normal server
7976 and client has router set (ie. global client) do not send the
7977 message to that client, as it is already routed to our router.
7979 * Implemented LEAVE notify type handling in silc_server_notify
7982 * Tested LEAVE command in router environment successfully. Tested
7983 with two routers, two servers and two clients.
7987 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7989 * Implemented SIGNOFF notify type handling in silc_server_notify
7992 * silc_server_remove_id now removes the client entry from all channels
7993 it has joined and thusly sends SIGNOFF notify type.
7995 * Rewrote the NAMES list generation in server by removing two excess
7996 loops. The lists are created now inside one loop.
7998 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8000 * silc_server_remove_channel_user checks now also global list
8001 for channel and client.
8003 * silc_server_new_channel_user checks now both local and global
8004 list for channel and client. Fixed a bug in client id decoding.
8005 Used to decode wrong buffer.
8007 * silc_server_channel_message checks now both local and global
8008 list for channel entry.
8010 * Tested channel joining (hence JOIN) in router environment
8011 successfully. Tested with two routers, two servers and two
8014 * Tested channel message sending in router environment successfully.
8016 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Added silc_server_save_channel_key into server.[ch] to save the
8019 received channel key in Channel Key payload processing. It is
8020 also used in JOIN command reply handling.
8022 Equivalent function silc_client_save_channel_key added into
8023 client.[ch] into client library.
8025 * Changed JOIN command reply to send information whether the channel
8026 was created or not (is existing already) and the channel key
8027 payload. Changed protocol specs accordingly.
8029 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8030 the request was sent by ID and not by nickname. Crashed on
8033 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8036 now correctly save the received data.
8038 * silc_server_free_sock_user_data now notifies routers in the
8039 network about entities leaving the network.
8041 At the same time implemented functions silc_server_remove_id
8042 and silc_server_send_remove_id to receive and send REMOVE_ID
8043 packets. The packet is used to notify routers in the network
8044 about leaving entities. The ID removed will become invalid in
8047 * Added function silc_idlist_del_server into server. Removes and
8048 free's server entry from ID list.
8050 * silc_server_private_message function now checks, if we are router,
8051 that the destination ID really is valid ID, naturally.
8053 * In router when NEW_ID packet is received (for new client) the
8054 hash of the Client ID is saved in the ID Cache but the
8055 client->nickname is set to NULL, instead of putting the hash
8058 IDENTIFY command now also checks that client->nickname must be
8059 valid. If it is not if will request the data from the server who
8060 owns the client. Added new function
8061 silc_server_command_identify_check.
8063 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8064 to set the command to already allocated Command Payload.
8066 * Tested private message sending in router environment with two
8067 routers, two servers and two clients. Fixed minor bugs and now
8070 * Fixed segfault from client's NAMES command. Used to crash if
8073 * Forwarded packets must not be routed even if it is not destined
8074 to the receiver. Changed server code comply with this.
8076 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Added `require_reverse_mapping' boolean value to ServerParams
8079 structure. If TRUE (not default) the server will require that
8080 the connecting host has fully qualified domain name.
8082 If the reverse mapping is not required and hostname could not be
8083 found the IP address is used as hostname.
8085 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8087 * Implemented version string checking to both client and server.
8088 The check is incomplete currently due to the abnormal version
8089 strings used in development version of SILC.
8091 * Changed all command functions in server to use the new
8094 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Changed char *data to unsigned char *data in ID Cache system to
8097 support binary data as ID Cache data. Changed code to support
8098 binary data in lib/silccore/idcache.c.
8100 * Renamed silc_server_packet_relay_command_reply to
8101 silc_server_command_reply as it is normal packet receiving
8102 function. Rewrote the function to accept command replys for
8103 servers and not only for clients.
8105 * Mark remote router always as registered server if we are connecting
8106 to it. Otherwise, commands sent by the router to us are ignored.
8108 * All ID List find routines now returns the ID Cache Entry pointer
8109 as well if requested.
8111 * WHOIS command works now in router environment, tested with two
8112 routers, two servers and two clients.
8114 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8115 in router environment (as it is almost equivalent to WHOIS) but
8116 hasn't been tested thoroughly. Added new functions:
8118 silc_server_command_identify_parse
8119 silc_server_command_identify_send_reply
8120 silc_server_command_identify_from_client
8121 silc_server_command_identify_from_server
8123 * Disabled route cache adding because adding two different ID's with
8124 same IP replaces the old cache entry thus giving wrong route.
8125 The entry->router->connection is always the fastest route anyway
8126 so route cache may not be needed. Of course, new routes maybe
8127 established after receiving the ID when the entry->router->connection
8128 might not be anymore the most optimal.
8130 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8132 * Add route cache for received ID for fast routing.
8134 * Added silc_server_packet_route to route received packet on router
8135 that is not destined to us.
8137 * Renamed silc_server_get_route to silc_server_route_get.
8139 * Added id_string and id_string_len fields into SilcServer to
8140 include encoded ServerID for fast comparing without excess
8141 encoding of the ID's.
8143 * Cleaned up WHOIS command on server side. Added following static
8146 silc_server_command_whois_parse
8147 silc_server_command_whois_check
8148 silc_server_command_whois_send_reply
8149 silc_server_command_whois_from_client
8150 silc_server_command_whois_from_server
8152 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8153 arguments in command replies. All command functions should be
8154 updated to use this macro.
8156 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Minor typo fixes on command reply handling on server.
8160 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8162 * Added silc_server_command_add_to_channel internal routine to add
8163 the client to the channel after router has created the channel and
8164 sent command reply to the server.
8166 * Added generic silc_server_send_command to send any command from
8169 * Use static buffer with ID rendering instead of duplicating data.
8171 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8173 * Fixed a channel user mode bug when joining to a channel server gave
8174 everybody channel founder rights, oops.
8176 * We mark ourselves as the router of the incoming server connection
8177 if we are router ourselves. This way we can check in some packet
8178 sending functions whether it is locally connected server. For
8179 incoming router connections we put NULL.
8181 * For router sending packets locally means now always sending the
8182 packet cell wide; to local clients and local servers. For normal
8183 server sending packet locally means sending it to only local
8186 * Fixed the JOIN command to really work in router environment. If the
8187 channel is created it is always created by the router. Router is
8188 also responsible of making the initial joining to the channel,
8189 sending JOIN notify to the sending server and distributing
8190 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8191 does not exist server doesn't do anything else but forward the
8192 command to the router which performs everything.
8194 * Added silc_server_send_channel_key function to send the Channel Key
8197 * Added silc_server_create_channel_key to create new channel key. The
8198 channel key is now re-generated everytime someone joins or leaves
8199 a channel, as protocol dictates. Note: channel->key_len is the
8202 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8205 packet_receive.[ch] to separate packet sending and receiving
8206 routines. The server.[ch] now includes everything else including
8207 actual packet processing (writing and reading data) and other
8210 Renamed silc_server_private_message_send_internal to
8211 silc_server_send_private_message. The routine is still though
8212 used only to relay private messages as server does not send
8213 private messages itself.
8215 Renamed silc_server_new_channel to silc_server_create_new_channel
8216 and added new function sicl_server_new_channel that handles the
8217 incoming New Channel packet. Added also new sending function
8218 silc_server_send_new_channel to send New Channel Payload.
8220 * Added new function silc_server_notify to process incoming notify
8221 packet to the server/router. Server may then relay the notify
8222 to clients if needed.
8224 * Added new function silc_server_new_channel_user to process incoming
8225 New Channel User packet. Router will redistribute the packet and
8226 send JOIN notify to its local clients and locally connected servers
8227 if needed. Normal server will send JOIN notify to its local client
8228 on same channel when received this packet. Added also corresponding
8229 sending function silc_server_send_new_channel_user to sent the
8232 * Added boolean route argument to send_notif_to_channel and
8233 packet_send_to_channel functions to attempt to route the packet
8234 if it is TRUE and send only locally if it is FALSE.
8236 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8238 * silc_server_replace_id now broadcasts the received replace ID
8239 packet if it is not broadcast packet already. The router must
8240 broadcast to inform other routers about changed ID.
8242 * Added backpointer to server's router into SilcServer context in
8243 silcd/server_internal.h.
8245 * Fixed silc_server_packet_broadcast to send correct broadcast
8248 * The channel key is now distributed to the local client as soon
8249 as it is received from the router (in router environment) so that
8250 no other packet may be sent for the channel until client has
8253 * silc_server_remove_channel_user now broadcasts the received
8254 Remove Channel User packet if it is not broadcast packet already.
8255 The router must broadcast to inform other routers about removed
8258 * Added users field into SilcPacketContext that is a reference count
8259 of the context. One can increase the reference count by calling
8260 silc_packet_context_dup which is now changed to just increase the
8261 reference count instead of duplicating the data. The reference
8262 count is decresed by calling silc_packet_context_free that will
8263 free the data after the reference count hits zero.
8265 For now on the packet context and everything allocated into it
8266 (including the raw packet from network) must be freed by calling
8267 the new silc_packet_context_free function. Added also new function
8268 silc_packet_context_alloc that must be used now to allocate the
8269 context. This also means that if a routine is asynchronous from
8270 silc_[client/server]_packet_parse_type the packet context must
8271 be duplicated by calling silc_packet_context_dup. Otherwise it
8272 gets free'd after silc_[client/server]_packet_parse_type returns.
8273 Also, one must remember that if packet is duplicated then its
8274 reference count must be decresed by calling the free function as
8275 many times as it was duplicated.
8277 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8278 from both client and server.
8280 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8282 * Made joining to a channel working in router environment.
8284 * Cleaned up JOIN command on server side and create function
8285 silc_server_command_join_channel internal routine to make the
8288 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8290 * Changed silc_command_pending list to SilcDList. Also, added
8291 `ident' field to SilcServerCommandPending structure to identify
8292 the reply and to call correct callback.
8294 Added silc_server_command_pending_check function to replace the
8295 corresnponding macro. The silc_command_pending list is not
8298 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8299 to set identifier to previously allocated Command Payload. It
8300 is used to set identifier for command when resending Command
8303 * Added silc_command_payload_encode_payload to encode Command
8304 Payload buffer from SilcCommandPayload structure.
8306 * Added silc_argument_payload_encode_payload to encode Argument
8307 payload buffer from SilcArgumentPayload structure.
8309 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Changed WHOIS command to support router connection on server side.
8312 The whois request is always sent to router unless the server is
8313 standalone server. After server has received the reply from the
8314 router will it send the reply to the client.
8316 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8317 broadcast received broadcast packet. The function is used only
8318 by router. The broadcast packet is always sent to the router's
8321 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8322 render given ID to printable string, for log files for example.
8324 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8326 * Made basic router to router connections working. At least they
8327 can now connect to each other but nothing really works the way
8328 they are supposed - yet.
8330 * Added new initiator token to RouterConnection configuration
8331 file in silcd/serverconfig.[ch]. It is used to tell whether we
8332 are the initiator to the remote router or whether we'll expect
8333 the other end to connect.
8335 * Moved registering of listener task to silc_server_init, hence
8336 the server starts listenning as soon as it is run, even if it
8337 does not have connections to other routers. Let's see how well
8340 * Changed default connection retry timeouts for more suitable in
8343 * Removed cipher and such arguments from silc_idlist_add_client
8344 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8345 Added new function silc_idlist_add_data to add the keys and stuff
8348 * Added SilcIDListData structure and added it to SilcClientEntry
8349 and SilcServerEntry as their first field in the structure. This
8350 way we can explicitly cast the ID entries to the SilcIDListData
8351 structure and get common data for the entries. In past, we had
8352 to first check what type of connection it is and then cast it to
8353 correct ID entry type. Now, we can directly cast the opaque
8354 pointer to the SilcIDListData (no matter what ID entry it actually
8355 is) and get the data needed.
8357 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8359 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8360 in some circumstances even if threre were timeout tasks, though not
8361 IO tasks, but tasks anyway. Now fixed.
8363 * Defined SilcServerConnection structure to hold connection specific
8364 stuff about directly connected servers and routers. The definition
8365 is currently in silcd/server_internal.h. I thought about having
8366 a bit more important role fro this struct but for now it is used
8367 only when connecting to other server (or router actually).
8369 * Added connecting retry support in server when connecting to
8370 router(s). The retry feature implement exponential backoff
8371 algorithm. Also, added SilcServerParams structure to hold default
8372 parameters for server. For now, it include these retry settings
8373 and are hard coded. After server is moded to be as Silc Server
8374 Library this structure will be more important.
8376 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Changed client librarys channel->clients table to SilcList and
8379 changed code accordingly.
8381 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8383 * Changed client's channel table to SilcList and changed code
8384 accordingly. Also changed SilcChannelClientEntry to include back-
8385 pointer to the channel so that client entry can use that structure
8386 as list as well and we have fast cross-reference to the channel.
8387 This change dramatically decreased the complexity of channel
8388 handling with client entry and vice versa (removed one extra
8389 loop when searching for channel entry from many functions).
8391 * Changed server->sim from table to SilcDList and changed code
8394 * NAMES command can now be used from user interface. It will show
8395 the user list on the channel, neatly.
8397 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8398 Code now saves realname of the user if it becomes available.
8400 * Renamed configure.in to configure.in.pre and made ./prepare
8401 script to automatically add correct version string to
8402 configure.in which it creates from configure.in.pre.
8404 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * NAMES command reply now shows users mode with the nickname when
8409 * Moved silc_client_ch[u]mode[_char] functions from
8410 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8411 place sucks, they are utility functions and should be in some
8414 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8416 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8419 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8423 * Added TRQ (efficient deque and list library) into lib/trq. This is
8424 a very good list library that is currently used in the SILC. Defined
8425 SilcList API over the library because I didn't like the API very
8426 much. See lib/trq/silclist.h for the API and examples of how to
8427 use the API. Fixed various places in the code to use the new
8428 SilcList API. The SilcList is meant for lists that has a structure
8429 already defined as a list. It is not suitable to add just some
8430 context to the list (in TRQ, the context is the list actually).
8432 So, I defined SilcDList that can be used for the purpose where
8433 predefined list structure does not exit. This can be used as
8434 such list. Now some context just can be added to the SilcDList.
8435 Currently this list is not used in the SILC just yet, though there
8436 are a lot places where this can replace dynamically allocated
8437 tables and I will fix these places, later, to use SilcDList.
8438 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8439 and use TRQ internally).
8441 Also fixed some annoying warning messages that the original TRQ
8442 code generated. Also minor changes to TRQ's Makefile.in.
8444 * Added support for querying by Client ID to both WHOIS and
8445 IDENTIFY commands into server, as required by the protocol.
8447 * Removed method function pointers from SilcBuffer structure. They
8448 weren't used to anything and just increased the context size for
8449 no good reason. This change also made silc_buffer_alloc and
8450 silc_buffer_free functions inline functions.
8452 * Disabled command flooding detection support until it's fixed so
8453 that it accepts commands in but does not execute them more than once
8456 * Added silc_net_localhost(), to return local hostname, into
8457 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8458 that must be initialized before calling silc_client_init.
8460 * Added new function: silc_server_send_notify_on_channels to send
8461 notify messages to all channels client has joined. It is assured
8462 that the message is sent only once per client.
8464 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8465 lib/silcutil/silcutil.[ch] as silc_format function. The new
8466 function is generic and is used by server as well, not only by
8467 the logging routines.
8469 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8470 the provided version string was not acceptable. Added new function:
8471 silc_ske_check_version into lib/silcske/silcske.h. The function
8472 must be implemented by the application (client or server) and it
8473 does not reside in the SKE library. The function checks the version
8474 string remote end sent.
8476 * Added back pointers (to opaque context and to SilcSocketConnection)
8477 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8479 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8480 duplicate packet context structure.
8482 * Changed `notify' client operation to send same arguments as client
8483 receives from server except for ID's. ID's are mapped to correct
8484 ID entry and that is returned. Also, if channel entry is not sent
8485 by server but the notify is for channel the channel entry is sent
8486 to application (otherwise application doesn't know that it is for
8487 channel (library gets it from packet's Destination ID)).
8489 * Added silc_client_remove_from_channels into client library to
8490 remove a client from all channels it has joined to. Used when
8491 received SIGNOFF notify from server. Added also new function
8492 silc_client_replace_from_channels to replace old ID entry with
8493 new ID entry on all channels. Used when received NICK_CHANGE
8496 * Fixed ID Cache list handling in silc_idlist_get_client in
8497 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8498 to get (or query) client by ID.
8500 * Updated TODO list.
8502 * Added connection authentication status message defined by the
8503 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8504 support for these into the code in client and server side.
8506 * Added generic function silc_client_send_command to send any command
8507 with variable argument list. Application should use this function
8508 to send commands if the command functions provided by the library
8509 does not suite for the application's user interface needs.
8511 * Added new `failure' client operation. Application is notified about
8512 received failure packet if client is executing a protocol. In this
8513 case the protocol's execution has failed.
8515 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8516 is required by the protocol.
8518 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8519 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8522 * Added status flag to SilcSKE object to indicate realtime status
8523 of the SKE protocol.
8525 * Application receives now exactly same command reply arguments as
8526 the library receives from server. However, if ID is received the
8527 corresponding ID entry is returned to the application (eg. Client
8528 ID is mapped to correct SilcClientEntry entry and that is returned).
8529 Changed command_reply client operation due to this change.
8531 * Changed all ID's in commands and in command replys as ID Payloads.
8532 Change affected both client and server side codes.
8534 All ID's sent in SILC network (with execption of ID's in SILC
8535 Packet header) are sent in ID Payload to support variable length
8538 * Server now notifies nick changes and notifies all clients on
8539 the channels about the new nickname (about the new Client ID,
8542 * Implemented CMODE command to change channel modes. Supports all
8543 channel modes defined by the protocol specs except ban and invite
8544 lists. (Also, private channel key mode is supported but support for
8545 setting private channel key in client is missing, thus, this mode
8546 has no effect on client side (except that server requires that the
8547 client uses private channel key and normal channel traffic does not
8550 Also, invite mode works per se, but INVITE command does not work
8551 yet correctly, so you can set channel as invite only channel but
8552 inviting clients to the channel does not work (it is yet to be
8553 thought what's the best way to do it).
8555 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8556 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8557 Implemented CUMODE command to change user's mode on the channel.
8558 Supports all modes defined by the protocol specs.
8560 * Added NAMES command reply to return users modes on the channel.
8562 * Removed unnecessary and slow ciphers from lib/silccrypt.
8564 * Set SO_KEEPALIVE option to connection sockets by default.
8566 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8568 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8569 redefined the Notify Payload into protocol specs.
8571 * Added silc_id_payload_parse_id to get ID directly from raw
8574 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8576 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8577 accept searching by Client ID as well.
8579 * Added support for LEAVE and SIGNOFF notify types in client library.
8581 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8582 to parse ID Payload from raw data.
8584 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8586 * Added flags parameter into silc_ske_assemble_security_properties
8587 function in lib/silcske/silcske.[ch].
8589 * Changed notify client operation to fit better for notify messages
8590 sent by server. The notify payload received from server is now
8591 passed to the application (after parsing it to SilcNotifyPayload).
8592 It is application's responsibility to retrieve the arguments
8593 from the payload and show the message the way it wants. The message
8594 sent by server is implementation specific.
8596 * Changed public keys to comply with the protocol specification.
8597 Old public keys are not supported anymore and are not compatible.
8599 * Removed nickname from Channel Payload as the latest draft removed
8600 it. The client must resolve the nickname from the NAMES command
8601 reply received when it joined the channel.
8603 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8605 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Fixed some errors in protocol specification drafts.
8609 * Created lib/silccore/silcnotify.c to implement Notify Payload
8610 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8611 generic payloads described by protocol specifications. The file
8612 includes implementations for ID Payload and Argument Payload.
8614 * Changed Command Payload implementation to use the new Argument
8615 Payload. Changed command_xxxx_payload to command_payload_xxxx
8616 to comply with SILC coding conventions.
8618 * Added suppport for Argument Payload handling in Notify Payload
8619 implementation as protocol requires it. Added the new support
8620 into server and client lib as well.
8622 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8624 * Added support for multiple nicknames on same channel. [n] is
8625 added locally to the nickname if there are more than one same
8626 nicknames on the channel.
8628 * Server now sends all nicknames that matched WHOIS request.
8629 Client also shows the list received from server.
8631 * Added TOPIC command to client side. User can now set and show
8632 current topic on channel.
8634 * Added MOTD command to client and server. Also, server sends the
8635 motd when client connects to the server.
8637 * Changed version strings to comply ISO 8601.
8639 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8641 * Fixed protocol error handling in client library. It should now
8642 cope even if the SKE fails for some reason.
8644 * Made new protocol specification drafts for submitting to IETF.
8646 * Implemented TOPIC command to server in silcd/command.c.
8648 * Added two new notify types into lib/silccore/silcnotify.h:
8649 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8650 notify nickname change and topic setting/change on a channel.
8652 * API change of command_reply operation in client library. The
8653 application gets now the status type received from server as well.
8655 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8657 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8659 * Cras fixed and optimized the packet handling even further and
8660 it should work now. Minor change to the prototype of function
8661 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8663 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8665 * Added new function into lib/silcutil/silcschedule.[ch]:
8666 silc_schedule_with_fd to select() a specified fd. The function
8667 returns after timeout expires or data arrives or goes. The
8668 function is used by packet routines to wait that all data is
8669 received from network.
8671 * Fixed data reading from network in lib/silccore/silcpacket.c.
8672 The code now assures that all data is read from the fd and then
8673 continues packet processing. This was a bug fix since the code
8674 used to drop some data in some circumstances.
8676 * Added new function into lib/silcclient/client.[ch]:
8677 silc_client_start_key_exchange to start key exchange after
8678 connection has been established to server. The code internally
8679 now uses this funtion but its main purpose was to provide it
8680 for applications that perform their own connecting. After
8681 application has created a connection it merely calls this
8682 function to start the key exchange between client and server.
8683 The library takes care of everything else after that.
8685 Updated also lib/silcclient/README to explain the usage of
8688 * Do not send to application information that connection has
8689 been established. Application gets notified it by connect
8692 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8694 * Applied cras's patch to add silc_schedule_one function. The
8695 function runs scheduler once and returns.
8697 * Fixed the scheduler after cras messed it up. The timeout
8698 handling works now as it's supposed to work.
8700 * Added into lib/silccore/ silcnotify.h to include notify
8701 message types support. Changed silc_server_send_notify*
8702 functions, in server.[ch], to support those new notify types.
8703 Added the support for the notify types into client library,
8704 as well. Added new notify client operation into ops.h in
8707 * Changed silc_server_packet_send_to_channel to send normal
8708 packets instead of just channel message packets. The function
8709 is now used to send the notify packets to channels. It is not
8710 used to send channel message packets anymore, as server never
8713 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8714 va_arg()s as it seems to require it nowadays. I guess, if SILC
8715 is compiled with older va_arg() the new code should work anyway.
8717 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Splitted core library. Core library (lib/silccore) includes
8720 now only SILC protocol specific core (and common) components.
8721 Created new utility library (lib/silcutil) that includes more
8722 generic purpose stuff. The stuff for util library was taken
8723 from the old core library. This was minor and easy split.
8725 * Created SILC Client Library (lib/silcclient) that includes
8726 implementation of the SILC client without user interface. This
8727 was major move from silc/ directory. The code has been changed
8728 so that it is transparent towards the user interface. The
8729 silc/ directory includes now the same user interface as before
8730 and it uses the new client library. Read lib/silcclient/README.
8731 Basicly, the client library performs everything else related
8732 to SILC except user interface handling. Also, configuration
8733 files are considered to be part of user interface and library
8734 does not handle them.
8736 This change also changed a lot of structures, function naming etc.
8737 Most important change was that SilcClientWindow object was
8738 renamed to SilcClientConnection in the client library. Created
8739 also new file lib/silcclient/ops.h. Also added new files
8740 silc/local_command.[ch] and silc/client_ops.[ch].
8742 All these changes were made to make it easier for user interface
8743 designers to create what ever user interface for the SILC client
8746 It is also expected that the server will be moved to lib
8747 directory as well and SILC Server Library will be created;
8748 sometimes in the future.
8750 * Removed Local commands from lib/silccore/silccommand.h as
8751 they are application specific and new client library does not
8752 handle any of those anymore.
8754 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8755 old client implementation in silc/.
8757 * Added support for callback functions in SILC_LOG_* macros.
8758 Application can now set its own callbacks that will be called
8759 instead of using the default functions that will always print
8760 the debug messages to stderr (or stdout). Also, debugging can
8761 now be disabled by setting silc_debug to FALSE and re-enabled by
8762 setting it to TRUE. Note, that logging will still work even
8763 if debugging is disabled.
8765 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8766 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8767 silc_log_reset_debug_callbacks.
8769 * To enable debugging in silc client one must give now -d
8770 option on command line.
8772 * Changed silc_schedule_init to automatically allocate task queues
8773 if they are not allocated before calling it.
8775 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8777 * Added GMP 3.1 into math library.
8779 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8781 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8782 a channel in SILC network. The packet is used by servers and
8783 routers to notify other routers that user has left a channel.
8784 This little feature was missing until now. Added the feature
8785 to protocol specification as well.
8787 Added functions: silc_server_send_remove_channel_user and
8788 silc_server_remove_channel_user into server.[ch].
8790 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8791 lib/silccore/silcpacket.h. However, they are not implemented
8794 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8796 * Fixed joining to a channel and sending channel messages
8797 between server and router. The channel message sending should
8798 now work inside a cell.
8800 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8802 * Fixed the private message sending between server and router.
8803 The private message sending should now work inside a cell.
8805 * Added silc_server_replace_id into server.[ch] to replace
8806 existing ID in the SILC network.
8808 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8809 and silc_idlist_replace_server_id into idlist.[ch] in server.
8811 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8813 * Fixed the server to server connections. Server can again now
8814 connect to router. Router to router connections probably does
8817 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8819 * Added dynamic protocol registering support. Now protocols can
8820 registered and unregistered on the fly. Patch by cras.
8822 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8824 * Added lib/contrib directory to hold routines that some platforms
8825 don't have but are needed by SILC.
8827 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8828 into lin/contrib to provide getopt() and getopt_long() for
8829 those who don't have it.
8831 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8833 * Added AWAY command to client. When away message is set and
8834 client receives a private message packet the client automatically
8835 replies to the sender with the away message.
8837 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8838 bug seemed to be the cause of recent problems when compiling
8841 * Added version detection support to SKE protocol specification
8842 and added the new changes to the SKE implementation as well.
8843 There were other minor changes in the SKE protocol as well.
8845 Many changes in lib/silcske/silcske.[ch] and in
8846 lib/silcske/payload.[ch].
8848 * Added ^U functionality, clear input line. Patch from cras.
8850 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8852 * Mainly small bugfixes on core library. Fixed some debugging
8853 logging and buffer overflow in silclog.c.
8855 * Updated config.sub and config.guess on the distribution tree.
8857 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8859 * Added command lagging support in server. Client may execute
8860 commands now only once in two seconds.
8862 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8864 * Optimized packet reception. MAC computation and checking is now
8865 also more optimized. A lot previously duplicated code is now
8866 used as generic by both client and server.
8868 * Fixed key pair generation in clientutil.c
8870 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8872 * Added into lib/silccore/silcbufutil.[ch] new function;
8873 silc_buffer_realloc.
8875 * Moved generic packet sending/encryption functions to
8876 lib/silccore/silcpacket.[ch] from client and server. Some
8877 rewriting of the functions.
8879 * Moved all generic packet reception/decryption functions to
8880 lib/silccore/silcpacket.[ch] from client and server. The
8881 packet processing is now much cleaner in both client and server.
8882 These were major changes in both client and server.
8884 * Created many common functions in server to do packet sending.
8885 Previously code were duplicated a lot, this has been removed
8888 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8890 * Rewrote major parts of the ID cache system. Don't know
8891 whether it is better now or not but at least the API is more
8894 * Major rewrite on ID cache stuff on client because of the ID
8895 cache API changes. Added idlist.c to client.
8897 * Also major rewrite on ID cache stuff on server as well.
8898 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8899 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8900 in hand, instead they are all put into the ID cache system now.
8901 All server_idlist_* routines uses ID cache now instead of
8902 traversing its own lists (those lists does not exist anymore).
8903 SilcIDList though still exists. Also, SilcXXXEntry's are
8906 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8908 * Finally made the SKE implementation compliant to the protocol
8909 specification. All mp integers are now binary encoded as
8910 opposed being HEX encoded.
8912 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8915 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8916 functions: silc_[encode/decode]_pem. Also added function
8917 silc_encode_pem_file to PEM encode with newlines ('\n') for
8920 * SILC public keys are now encoded either PEM or binary. Same
8921 option is for private keys as well. By default private keys
8922 are binary encoded and public keys PEM encoded. Silly HEX
8923 encoding were removed.
8925 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8926 function to create fingerprints.
8928 * Fixed a bug in SHA1; does not change the original data anymore.
8930 * Partly implemented INFO command on client and server side.
8931 Fixed CLEAR command. Changes to SERVER command; show current
8932 server(s) when giving command without arguments. Added
8933 VERSION command to client.
8935 * Added check to server that unregistered connections cannot
8936 execute commands (unless it is specificly allowed).
8938 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8940 * Fixed screen refresh.
8942 * Fixed channel joining bug from client. On some circumstances
8943 client tried to join to a channel it had already joined.
8945 * Added public key verification process into client's protocol.c.
8946 The client now verifies the public key from user and saves
8947 it into ~./silc/serverkeys/ directory.
8949 Added into: clientutil.[ch]: silc_client_verify_server_key.
8951 * Changed SKE protocol's silc_ske_initiator_finish function
8952 to accept callback function that verifies the received public
8953 key. Removed old silc_ske_verify_public_key function.
8955 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8957 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8958 silc_pkcs_private_key[_data]_set.
8960 * Made the password and public authentication more cleaner in
8961 server's protocol.c.
8963 * Removed historic and obsolete protocol `channel_auth' from
8964 both client and server.
8966 * Removed wrong way of sending command status messages from
8967 server to client in server's command.c. The old way violated
8968 protocol specification.
8970 Changes to silccore/silccommand.[ch]: removed
8971 silc_command_encode_status_payload -> not needed anymore,
8972 changed silc_command_encode_payload_va to accept extra
8973 argument on variable argument list. The argument type must
8974 now be provided to the function. Also, added new function:
8975 silc_command_encode_reply_payload_va which is same as
8976 normal command_encode_payload_va except command status type
8977 is provided as extra argument.
8979 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8981 * Added ~./silc directory handling. The directory includes the
8982 public and private keys for the client.
8984 Added silc_client_check_silc_dir, silc_client_create_identifier
8985 and silc_client_load_keys.
8987 * Implemented SILC protocol compliant public key. Added public
8988 and private key saving to and loading from files.
8990 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8991 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8992 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8993 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8994 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8996 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8997 silc_pkcs_load_[public/private]_key.
8999 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9001 * Added silc_server_get_route (route.[ch]) to get connection
9002 data for the fastest route for given ID.
9004 * Implemented INVITE command on client and server. The command
9005 were re-defined in the SILC Protocol Specification and the
9006 implementation now complies with the specification.
9008 * Implemented PING command on client and server.
9010 * Implemented NAMES command on client and server. The server side
9011 supports currently only normal server not router server yet.
9012 Some changes to NAMES definition in SILC protocol specification.
9014 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9016 * Implemented LEAVE command on client and server.
9018 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9019 again. This change was made to the protocol as well. Server
9020 should not violate the protocol specification anymore.
9022 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9024 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9025 was tested. SOCKS4 was not but should work anyway.
