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

548 the watcher list too. Affected file silcd/packet_receive.c.
550 * Do not allow normal server to force founder mode away
551 from router if the founder mode is already set. Affected
552 file silcd/packet_receive.c.
554 * Remove the client entry with watch notify types with short
555 timeout, and not directly, so that other notifys can be
556 retrieved too. Affected file lib/silcclient/client_notify.c.
558 * Display notification about data messages that cannot be
559 displayed. Affected files irssi/src/silc/core/client_ops.c,

562 Sun May 19 18:59:00 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
564 * Fixed the CHANNEL_CHANGE notify handling in client libary
565 to not use freed memory. Affected file is
566 lib/silcclient/client_notify.c.
568 * Fixed CUMODE_CHANGE notify handling in server. Affected
569 file silcd/packet_receive.c.
571 * Fixed USERS command to support empty channels. Affected
572 file silcd/command.c.

1082 client and server. Protocol TODO #15. Affected files are
1083 silcd/command.c, lib/silcclient/command_reply.c. The channel
1084 entry is now returned to application in the `command_reply'
1087 * Rewrote the version SKE version checking in client libary
1088 and in server to use the silc_parse_version_string. Affected
1089 files are lib/silcclient/protocol.c, silcd/protocol.c.
1091 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1092 commands that was missing it, and updated protocol specs and
1093 the server implementation. Protocol TODO #10. The affected
1094 file is silcd/command.c.
1096 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1097 generic reply to a generic request (REQUEST flag), and
1098 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1099 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1100 to define the payload for DATA flag. Added the flags to
1101 the implementation. Protocol TODO #9. Affected file is
1102 lib/silccore/silcchannel.h.
1104 Changed the client library to return the message length
1105 to application as well in the channel_message and private_message
1106 client operations. Affected files are
1107 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1108 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1109 and lib/silcclient/client_ops_example.c.
1111 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1112 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1113 the channel. Updated protocol specs and impelemented this
1114 to client and server. Protocol TODO #6. Affected files are
1115 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1116 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1118 Added new options m and M to CMODE command in Irssi SILC
1119 client to set these modes.
1121 * Deprecated all administrative commands from SILC protocol
1122 since they are highly implementation specific commands.
1123 Updated protocol specs. Moved the old commands in
1124 implementations to private range of command types. Affected
1125 files are silcd/command.c, lib/silcclient/command.c and
1126 lib/silcclient/command_reply.c. Protocol TODO #8.
1128 * Fixed a bug in server where sending unknown command crashes
1129 the server. Affected file silcd/command.c.
1131 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Added SILC_PROTOCOLVERSION macro to check protocol version
1134 of a socket connection. The affected file is
1135 lib/silcutil/silcsockconn.h.
1137 * Added better error logging in rekey protocol. Affected file
1140 * Do not check public key types in SKE during rekey. Affected
1141 file lib/silcske/payload.c.
1143 * Fixed the rekey protocol with PFS, which was totally broken.
1144 Affected file silcd/protocol.c.
1146 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1148 * Some client implementations quit network by doing first LEAVE
1149 and then immediately SIGNOFF (like Bombyx). We now do check
1150 after a short time after LEAVE notify and check whether the
1151 client is still valid after LEAVE, and if not we remove it from
1152 cache. Affected file is lib/silcclient/client_notify.c.
1154 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1156 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1157 it's good not to have security holes here.
1159 * Fixed a negative refcount situtuation for the config context.
1160 Affected file is silcd/serverconfig.c.
1162 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1164 * ROBOdoc documented lib/silcutil/silcutil.h.
1166 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1168 * Optimized even more the SilcPacketContext structure. Now
1169 totally saved 16 bytes of memory per context after optimization.
1170 Affected files are lib/silccore/silcpacket.[ch].
1172 * Made strict checks for valid SILC IDs. Affected file is
1173 lib/silccore/silcid.c.
1175 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Changed the object argument for silc_cipher_register,
1178 silc_hash_register, silc_hmac_register and silc_pkcs_register
1179 to const. Affected files are lib/silccrypt/silccipher.[ch],
1180 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1182 * Changed the silc_get_username and silc_get_real_name to
1183 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1185 * Fixed the Irssi SILC Client to use the silc_get_username and
1186 silc_get_real_name insted of glib routines since the glib
1187 routines only corrupt stack. Fixes the Irssi SILC to work in
1188 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1190 * Fixed the Irssi to not use g_get_home_dir since it crashes
1191 or returns garbage on cygwin and corrupts stack. Added function
1192 get_home_dir to Irssi routines. Affected files are
1193 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1195 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Made some structure optimizations. SFTP memory FS MemFSEntry
1198 entry structure. Optimized SilcTask structure. Optimized
1199 SilcPacketContext structure.
1201 Affected files lib/silcsftp/sftp_fs_memory.c,
1202 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1204 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * And yet again reverted back the config thing since Johnny
1207 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1210 * Fixed memory leaks from config object. Affected files are
1211 silcd/serverconfig.[ch].
1213 * Added support for adding new connections to the server in rehash.
1214 After rehash they take effect.
1216 Added support for changing the maximum allowed connections in
1217 rehash. The number can grow but going smaller is not supported.
1219 Added function silc_server_num_sockets_by_remote to the
1220 silcd/server_util.[ch].
1222 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1224 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1226 * Added preliminary checking during config parsing for a valid
1227 public/private key and removed further checks in the code.
1228 Affected files are silcd/serverconfig.[ch], server.c.
1230 * Moved functions silc_server_drop() and silc_server_daemonise()
1231 from server.c to silcd.c since they are stricly related to
1232 the application activity.
1234 * Reverted a small part of the automatic ref/unref since
1235 it caused a double unref in some situations. Affected
1236 files are silcd/silcd.[ch], server.c, serverconfig.c.
1238 * Added some .cvsignore files in the lib directory.
1240 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Fixed silc_net_gethostbyaddr to correctly resolve by
1243 address. Affected file lib/silcutil/silcnet.c.
1245 * Fixed the notify relaying to client. The HMAC to be used
1246 with relayed packets ws wrong and caused decryption failure
1247 at the client end. Affected file is silcd/packet_receive.c.
1249 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1251 * Created new branch silc_protocol_1_0_branch.
1253 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1255 * Changed the silc_server_config_* routines to be SilcServer
1256 independent. They are now officially application specific code
1257 and not part of generic server implementation. Affected files
1258 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1260 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1262 * Added automatic referencing of config context in the
1263 silc_server_config_alloc, and automatic unreferencing in the
1264 silc_server_config_destroy. Affected files are
1265 silcd/serverconfig.[ch], silcd/silcd.c.
1267 * Fixed the silc_log_quick handling in the logging routines.
1268 It didn't log quickly when it was TRUE. Affected file is
1269 lib/silcutil/silclog.c. Also the flush delay was set even
1270 if it was 0 in config file. Affected file is
1271 silcd/serverconfig.c.
1273 * Added support for changing key pair of the server in rehash.
1274 Affected file silcd/server.c.
1276 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1278 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1279 too early, before getting the channel entry. Affected file
1280 is silcd/packet_receive.c.
1282 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1284 * Added functions silc_server_config_[ref/unref], these are used
1285 to prevent that the config object is destroyed.
1287 No longer directly affect global variables silc_log_quick and
1288 silc_log_delay, they are first cached inside the config object
1289 and then applied with silc_server_config_setlogfiles().
1291 silc_server_config_set_defaults() is now internal to
1292 serverconfig.c, there are no reasons to show this internal stuff
1295 Affected files are silcd/serverconfig.[ch].
1297 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1298 fprintf's to stderr, since some code may be executed again after
1299 the server went into the background. Affected files are
1302 * Added rehash support. Added function silc_server_rehash() that
1303 will perform all the basic tasks of the rehashing procedure.
1305 * Added command line option `-x, --hexdump'. This will enable the
1306 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1307 The option `--hexdump' implies `--debug'.
1309 * Fixed a bad bug in the logging APIs (silcutil library) where
1310 the application would crash after calling silc_log_reset_all().
1312 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1314 * Fixed the KICKED notify handling in client library to
1315 correctly remove the channel and all entries from the
1316 channel when I was kicked. This bug crashed the client.
1318 Fixed yet another but in KICKED notify handling to remove
1319 the kicked client correctly from the channel.
1321 Affected file is lib/silcclient/client_notify.c.
1323 * Fixed a minor bug in looking up correct client entry
1324 in KICKED notify in server. Affected file is
1325 silcd/packet_receive.c.
1327 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1328 sources correctly to distribution. Fixes --with-gmp option.
1330 * Removed the manual rehashing from ID Cache, and changed it
1331 to use the SILC Hash Table's auto rehash feature. Affected
1332 file is lib/silccore/silcidcache.c.
1334 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Fixed a bug in the silc_client_nickname_format function that
1337 handles the multiple same nickname formatting. Two clients
1338 with same nickname caused problems after the first one left
1339 and rejoined. It didn't format the nickname correctly.
1340 Affected file is lib/silcclient/idlist.c.
1342 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1344 * Don't change the topic if olod topic is same as new one.
1345 Affected file is silcd/packet_receive.c.
1347 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1349 * Added cross-reference support to the SILC Documentation
1350 generator. All types across all HTML files are now cross-
1351 referenced. Affected files util/robodoc/generator.c and
1352 scripts/silcdoc/silcdoc.
1354 * Added file lib/silcutil/silctypes.h to include all the
1355 arithmetic type definitions and some macros. Removed
1356 includes/bitmove.h and moved macros to silctypes.h.
1358 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1360 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1362 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1364 * Added `type' argument to silc_id_payload_parse_id function which
1365 now returns the type of the ID to the sent pointer. Affected
1366 file is lib/silccore/silcid.[ch].
1368 * Added check for CMODE_CHANGE notify type that mode change is
1369 allowed by the sender. Affected file silcd/packet_receive.c.
1371 * Added check for CUMODE_CHANGE notify type that mode change is
1372 allowed by the sender. Affected file silcd/packet_receive.c.
1373 Added the ID type as CUMODE_CHANGE notify type as argument
1374 to the `notify' client operation. Affected files are
1375 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1377 * Added function silc_client_add_server to the client library.
1378 Added support for resolving also channel and server info when
1379 received unknown entity in notify packet. Affected files are
1380 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1382 * Added function silc_command_get_status to return the command
1383 status from the command reply's argument payload. Affected files
1384 are lib/silccore/silccommand.[ch].
1386 * Added check for KICKED notify type that the kicking is
1387 allowed by the client. Affected file silcd/packet_receive.c.
1389 * Created function silc_get_input which can be used to get input
1390 (echo on or off) from user on command line. Affected files are
1391 lib/silcutil/silcutil.[ch].
1393 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Optimized silc_server_packet_relay_to_channel function.
1396 Added new function silc_channel_message_payload_encrypt which
1397 can be called directly if channel message payload needs to
1398 be encrypted and is already encoded (no need to call _encode
1399 function). Packet relaying is now done by router without any
1400 extra memory allocations. Affected files are
1401 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1402 silcd/packet_send.c.
1404 * Fixed the INVITE notify handling. It took wrong arguments
1405 as invite list and invite delete. Affected file is
1406 silcd/packet_receive.c.
1408 * Added check for TOPIC_SET notify type that the topic change is
1409 allowed by the client. Affected file silcd/packet_receive.c.
1411 * Added check for INVITE notify type that inviting is allowed by
1412 the client. Affected file silcd/packet_receive.c.
1414 * Changed the silc_server_client_on_channel to return the
1415 SilcChannelClientEntry as well. Moved the function
1416 silc_server_check_cmode_rights to server_util.[ch].
1417 Affected files are silcd/server_util.[ch], silcd/command.c.
1419 * Added function silc_server_check_umode_rights to check whether
1420 changing client's user mode is allowed. Added check for
1421 UMODE_CHANGE notify type that the umode change is allowed
1422 by the client. Affected files are silcd/server_util.[ch],
1423 silcd/packet_receive.c and silcd/command.c.
1425 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1427 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1428 ID length. It ignored that ID can be IPv6 based as well.
1429 Affected file lib/silccore/silcpacket.h.
1431 * Fixed the silc_id_id2str and silc_id_str2id to take the
1432 IPv6 address offset's into consideration. Affecte file is
1433 lib/silccore/silcid.c.
1435 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1437 * Fixed the internal Unix scheduler functions to check for
1438 NULL context they may receive. The affected file is
1439 lib/silcutil/unix/silcunixschedule.c.
1441 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1443 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1444 can specify different directory with --home command line
1445 parameter. Affected files irssi/src/silc/core/client_ops.c,
1448 * SILC-specific commands aren't now executed if the active server
1449 isn't of SILC-type, so there won't be problems with having
1450 IRC and SILC protocol support in same client. Affected files
1451 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1454 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1456 * Improved the signal support in SILC Schedule. Added new
1457 function silc_schedule_signal_call which is used by application
1458 to mark a signal to be called. It is now safe to perform
1459 any kind of tasks in signal callbacks since it is guaranteed
1460 that the application specified signal callback is called
1461 after the signal is over. Affected files are
1462 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1464 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Added `name' field to SilcChannelPrivateKey to represent
1467 application given name for the key. Moved also the context from
1468 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1469 Added the `name' argument also to the function
1470 silc_client_add_channel_private_key.
1472 Added function silc_client_current_channel_private_key to set the
1473 current channel private key in use.
1475 Added "change" command to KEY command which can be used to change
1476 the current channel private key. Bound the command also to
1477 alt+K (Alt+Shift+k).
1479 Also affected files lib/silcclient/client_channel.c,
1480 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1482 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1484 * Added silc_rng_get_byte_fast function in to the
1485 lib/silccrypt/silcrng.[ch].
1487 * Changed the interface of silc_packet_assemble and the
1488 silc_packet_send_prepare. If silc_packet_assmble is now
1489 called the application does not call silc_packet_send_prepare
1490 because the library will call it automatically. These
1491 interfaces now also return a reference to the outgoing buffer
1492 which includes the assembled packet, which the application can
1493 use to encrypt the packet.
1495 Affected files are lib/silccore/silcpacket.[ch],
1496 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1497 silcd/packet_send.c, server_backup.c and packet_receive.c.
1499 * Fixed a packet sending bug on very high load, where outgoing
1500 packet queue wasn't handled correctly and packets got corrupted.
1501 Affected files are lib/silcutil/*/silc*sockconn.c,
1502 lib/silcclient/client.c and silcd/server.c.
1504 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1506 * Added macro SILC_PACKET_DATALEN which can be used during
1507 packet assembling to check whether the data to be added to
1508 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1509 len is truncated until it fits it.
1511 Added checks for maximum length of channel message payload and
1512 private message payload also.
1514 Added checks for maximum packet length in server and in
1517 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1518 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1519 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1520 lib/silcclient/client_prvmsg.c.
1522 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1524 * Added silc_server_packet_queue_purge call to the
1525 silc_server_disconnect_remote to assure that all data in the
1526 queue before disconnecting is sent to the network. Affected
1527 file silcd/server.c.
1529 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Added the deleting of server's own ID cache entry to the
1532 silc_server_free function. Free also everything else that
1533 has been allocated in silc_server_init. The affected file
1536 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1538 * Added functions silc_parse_version_string, silc_version_to_num,
1539 and silc_ske_parse_version to parse SILC protocol style version
1540 strings. Affected files lib/silcutil/silcutil.[ch] and
1541 lib/silcske/silcske.[ch].
1543 * Added new configuration params: version_protocol, version_software
1544 and version_software_vendor to specify what version the remote
1545 host must at least be to be able to connect to server. The vendor
1546 string can be regex matched too. Added new function
1547 silc_server_connection_allowed to check maximum number of allowed
1548 connections, and allowed versions for incoming connections.
1549 Affected files are silcd/server.c, server_util.[ch] and
1552 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1554 * Added preliminary support for signals in scheduler. The
1555 signals we care about are now blocked always when the scheduler
1556 is locked. This way we can synchronise the use of signal with
1557 scheduler. It is guaranteed that when signal occurs the scheduler
1558 is not locked, and thus new tasks can be safely added to the
1561 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1562 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1563 Added new platform specific routines
1564 silc_schedule_internal_signals_[un]block and
1565 silc_schedule_internal_signal_[un]register.
1567 Added new functions to SILC Schedule API:
1568 silc_schedule_signal_[un]register. Each signal that application
1569 is going to use should be registered to the scheduler.
1571 Affected files are lib/silcutil/silcschedule.[ch],
1572 lib/silcutil/*/silc*schedule.c.
1574 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1576 * Check for unauthenticated client and server in the
1577 silc_server_new_client and silc_server_new_server functions.
1578 Affected file silcd/packet_receive.c.
1580 * Added function silc_string_is_ascii to check whether given
1581 string is 7-bit ASCII string. Affected files are
1582 lib/silcutil/silcutil.[ch].
1584 * Added function silc_id_is_valid_server_id into the
1585 silcd/serverid.c and added checking for valid Server ID's in
1586 silc_server_new_server. The Server ID must always be based
1587 on the server's public IP address.
1589 * Added logging of DISCONNECT packet message in the server.
1590 Affected file silcd/server.c.
1592 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1594 * Changed all library interfaces that use Global RNG to also
1595 accept SilcRng as argument. Affected files are
1596 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1597 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,

1599 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1600 lib/silccrypt/rsa.c.
1602 * Added function silc_pkcs_generate_key to the
1603 lib/silccrypt/silcpkcs.[ch] for applications so that they
1604 don't need to do pkcs->pkcs->init calls anymore.
1606 * Remove SilcSocketConnection from the SFTP API since it really
1607 wasn't needed there. The application has the information
1608 saved in its contexts anyway and the SFTP layer doesn't need
1609 know about it. Affected files lib/silcsft/silcsftp.h and
1610 lib/silcsftp/sftp_[server/client].c.
1612 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1620 algorithm list on EPOC. Affected files are
1621 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1624 * Fixed the handling of third parameter of KICKED notify, since
1625 it was mistakenly updated to SILC Protocol 1.0 even though it
1626 is to be included in 1.1. Since it is not in 1.0 it is not
1627 mandatory, and this fix now handles it only if it is provided,
1628 and it is not error if it is not provided. Affected file
1629 lib/silcclient/client_notify.c.
1631 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1638 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1640 * Check for valid socket connection in client entries before
1641 sending any messages. Fixes a crash, but doesn't fix some
1642 other underlaying bug that is lurking there. Affected
1643 file silcd/packet_send.c.
1645 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1647 * $usermode, $cumode and $cumode_space expandos shouldn't do
1648 anything with non-SILC server records. Affected file
1649 irssi/src/silc/core/silc-expandos.c
1651 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed the silc_net_check_[host/local]_by_sock to support
1654 IPv6 bound sockets as well. Now they can return IPv6 addresses
1655 as well. Affected file lib/silcutil/silcnet.c.
1657 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1658 Affected lib/silcutil/unix/silcunixnet.c.
1660 * Fixed ID rendering (at least on some platforms, not NetBSD)
1661 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1663 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1665 * Added silc_hash_public_key and silc_hash_public_key_compare
1666 functions to be used with SilcHashTable. They can be used to
1667 hash public keys and compare public keys in hash table. Affected
1668 file lib/silcutil/silcutil.[ch].
1670 * Added support for specifying multiple public keys for Client
1671 connection section in server configuration file. This makes it
1672 possible to accept multiple public keys from same host, or to
1673 make a section that accepts any incoming host, and have the
1674 accepted public keys listed in the section.
1676 Added functions silc_sever_[find/get]_public_key, added the
1677 support for this actually to all connection sections but only
1678 the Client section is currently allowed to specify multiple
1681 Affected files are silcd/server.c, server_internal.h,
1682 command.c, protocol.c, server_util.[ch], packet_receive.c.
1684 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1688 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1690 * If silc_debug is TRUE, also output standard logging messages
1691 to stderr with the debug output.
1693 Made silc_log_reset_all() flushing all channels before returning.
1694 Also fixed some documentation typos.
1696 Affected files are lib/silcutil/silclog.[ch].
1698 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1700 * Fixed the server to check correctly the amount of connections
1701 from single host, by checking also the type of the connection.
1702 Fixed also the comparison of number of connections and number
1703 of allowed connections. Affected files are silcd/server.c,
1706 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Fixed the USERS command reply to save the user's mode on the
1709 channel as well. Fixed JOIN command reply to check whether a
1710 client is on channel already and not join it twice. Affected
1711 file lib/silcclient/command_reply.c.
1713 * Added new file silc-expandos.c into irssi/silc/core/ to return
1714 various stuff for various signal for the statusbar etc. updating.
1715 Now Irssi SILC client prints channel user modes etc. on the
1718 * The user mode (like server/router operator changes) is now shown
1719 on the Irssi SILC client's statusbar. The affected files are
1720 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1722 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1724 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1725 to SILC_SCHEDULE_[UN]LOCK macros.
1727 * Added more error printing to logs in server code. Affected
1728 files silcd/server.c and silcd/protocol.c.
1730 * Fixed -S option parsing in Irssi SILC Client. Affected file
1731 irssi/src/silc/core/silc-core.c.
1733 * Added silc_buffer_alloc_size function. Affected file is

1758 * Changed all integer type names:
1759 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1760 to avoid collisions with other libraries using same type names
1763 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Added `prefer_ipv6' argument to the functions
1766 silc_net_gethostbyname[_async]. If it is TRUE it will return
1767 IPv6 address over IPv4. If FALSE IPv4 address is returned
1768 even if IPv6 address was found. Affected files
1769 lib/silcutil/silcnet.[ch].
1771 * Added support silc_net_create_connection[_async] to fallback
1772 to IPv4 address if IPv6 address could not be used (like if

1782 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1784 * Added automatic extern "C" { ... } for C++ compilers so the
1785 application does not need to define them. Affected file
1786 includes/silcincludes.h.
1788 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1789 old name went against naming convention. Applications now
1790 include "silcclient.h" instead of "clientlibincludes.h".
1791 Removed includes/clientlibincludes.h, it is redundant now.
1793 * Renamed includes/version.h to silcversion.h.
1795 * Added really preliminary support for OS/2 into the util
1796 library. Only thread & mutex API is implemented, others
1797 are still to be implemented. Created the lib/silcutil/os2/
1798 directory. Created also file includes/silcos2.h.
1800 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1831 * Added `user_count' to the SilcChannelEntry which now tells the
1832 number of users on the channel. The user count is now saved
1833 in normal server of global channels as well. Affected files
1834 silcd/server.c, idlist.h, packet_receive.c and command.c.
1836 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1837 include file utility functions.
1839 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1840 instead of calling directly OS routines.
1842 * Fixed NICK change printing in Irssi SILC Client. Fixed
1843 KICKED notify printing in Irssi SILC Client. Affected file
1844 irssi/src/silc/core/client_ops.c.

1847 client_entry->channels hash table everytime nick is changed.
1848 Affected file lib/silcclient/client.c.
1850 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1852 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1853 the SKE interface a bit.
1855 * Fixed padding problem in PKCS#1. The padding was not actually
1856 random since the random number generator was used incorrectly.
1857 This security bug affects only when encrypting with PKCS#1, and
1858 it is not currently used at all in SILC. SILC only use signing
1859 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1861 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1919 is now done in silc_core_init() which also fixes autoconnecting
1922 Affected files irssi/src/silc/core/silc-core.c,
1923 irssi/src/fe-text/silc.c.
1925 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1927 * Added new configuration options and blocks:
1928 keepalive_secs, reconnect_count, reconnect_interval,
1929 reconnect_interval_max, reconnect_keep_trying and

1931 implemented the connection parameters when connecting as
1932 initiator and when accepting connections as responder.
1934 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1935 whether given configuration value has been given already.
1937 Affected files silcd/serverconfig.[c], server.[c].
1939 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1940 algorithm parts and created new file silcalgs.conf, that
1941 is now included from the example_silcd.conf.in.
1943 * Optimized the silc_server_connect_to_router_second to take
1944 the connection configuration object from the SilcServerConnection
1945 object instead of finding it during the connecting phase.
1946 Added the configuration object to SilcServerConnection struct.
1947 Affected files silcd/server_internal.h, server.c.
1949 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1951 * Add the client on channel after it was resolved at the
1952 channel message receiving, and it was not already on the
1953 channel. Affected file lib/silcclient/client_channel.c.
1955 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1971 authentication to be set at the same time.
1973 Added `prefer_passphrase_auth' setting in config file which
1974 can be used to set to prefer passwd auth if both passwd and
1975 public key is set. If not set, public key is preferred.
1976 This has effect only when being initiator (responder will try
1979 Added support for authentication with passphrase and public key
1980 at the same time. The passphrase is tried first always since
1981 it is faster to check.
1983 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1985 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2031 * Fixed the file transfer's key agreement payload to include
2032 zero port also if the hostname is NULL because it could not
2035 Call file transfer monitor callback now also if error occurs
2036 during key agreement protocol.
2038 Changed the silc_client_file_send interface to return the
2039 SilcClientFileError instead of session id. The session ID
2040 is returned into pointer provided as argument.

2057 file lib/silcutil/silclog.c.
2059 * Fixed the channel message payload decryption in the function
2060 silc_channel_message_payload_decrypt to not modify the original
2061 buffer before it is verified that the message decrypted
2062 correctly. Otherwise, next time it is called with correct
2063 channel key it won't encrypt since the payload is corrupted.
2064 Affected file lib/silccore/silcchannel.c.
2066 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2081 the callback returned.
2083 Do not allow auto rehashing of hash table during the
2084 silc_hash_table_foreach operation, for same reasons as it is
2085 not allowed for SilcHashTableList. Affected files are
2086 lib/silcutil/silchashtable.[ch].
2088 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2096 * Fixed private message handling. It used some old code that
2097 caused the client to crash. Affecte file is
2098 lib/silcclient/client_prvmsg.c.
2100 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2102 * Added function silc_client_add_channel,
2103 silc_client_replace_channel_id, and removed functions
2104 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2105 from client library.
2107 * Added cross reference of the joined channels to the
2108 SilcClientEntry, and changed the SilcChannelEntry's
2109 users list to SilcHashTable. The affected files are
2110 lib/silcclient/idlist.[ch].
2112 * Fixed a bug in hash table tarversing. While the hash table
2113 is traversed with SilcHashTableList the table must not be
2114 rehashed. It is now guaranteed that auto rehashable tables
2115 are not rehashed while tarversing the list. Also defined that
2116 silc_hash_table_rehash must not be called while tarversing
2117 the table. Added function silc_hash_table_list_reset that must
2118 be called after the tarversing is over. The affected files are
2119 lib/silcutil/silchashtable.[ch].
2121 * Changed all hash table traversing to call the new
2122 silc_hash_table_list_reset in server and in client library.
2124 * Added function silc_client_on_channel to return the
2125 SilcChannelUser entry if the specified client entry is joined
2126 on the specified channel. This is exported to application as
2127 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2129 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2131 * Fixed founder regaining problem with JOIN command on normal
2132 server. The notify for mode change must be sent always and
2133 not only if !cmd->pending. Affected file silcd/command.c.
2135 * Fixed the WHOWAS command's reply sending to support the
2136 lists correctly. Affected file silcd/command.c.
2138 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2140 * When sending JOIN command to router for processing the
2141 sender's old command identifier was not saved back to the
2142 sender's command context, fixed now. The affected file is
2145 * Create the key in JOIN command of the router did not return
2146 the channel key, added check for this. Affected file is
2149 * Fixed a channel ID update bug in JOIN command reply. Do
2150 not directly upgrade the ID but call the function
2151 silc_idlist_replace_channel_id if the ID was changed.
2152 Affected file silcd/command_reply.c.
2154 * Fixed memory leaks from command calling if it would fail.
2155 Affected file silcd/command.c.
2157 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2159 * Applied patches from cras:
2161 Memory leak fixes around libaries, irssi window resize fix,
2162 new silclist.h and silcdlist.h, all extern inline changed to
2165 * Removed dotconf from lib/dotconf, not needed anymore.
2167 * Removed TRQ from lib/trq, not needed anymore.
2169 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2170 with server connections. Later this will be configurable
2171 in config file after new config file is done. Affected file
2174 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2176 * Fixed a crash in server related to channel announcements.
2177 Affected file silcd/server.c.
2179 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2181 * Fixed memory leaks in silc_server_create_new_channel*
2182 functions. Affected file silcd/server.c.
2184 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2185 which ID was changed. This way the router will send the
2186 user list for the channel again, and server won't be in
2187 desync in some rare circumstances. Affected file is
2188 silcd/packet_receive.c.
2190 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2192 * Check for NULL socket pointer in the function
2193 silc_server_packet_send_to_channel_real. Affected file
2194 silcd/packet_send.c.
2196 * Fixed the BAN notify handling to correctly remove ban
2197 list. Affected file silcd/packet_receive.c.
2199 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2201 * Fixed some header addition to Toolkit distribution in
2202 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2204 * Added lib/silcclient/client_ops_example.h as an template
2205 file for application programmers to quickly start using
2206 the SilcClientOperation functions in their application.
2207 Updated the lib/silcclient/README as well to tell about this
2208 nice file made available.
2210 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2212 * Call silc_server_remove_from_channels when removing client
2213 entry when NO_SUCH_CLIENT_ID was received. Affected file
2214 is silcd/command_reply.c.
2216 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2218 * Added server & router operator statistics updating. Affected
2219 file silcd/packet_receive.c and silcd/command.c.
2221 * Fixed the SERVER_SIGNOFF notify handling on normal server
2222 not to save the history information for clients. Same was
2223 fixed earlier in remove_clients_by_server function, but not
2224 here. Affected file silcd/packet_receive.c.
2226 * Raised the default connection-retry count from 4 to 7 in
2227 server. Affected file silcd/server.h.
2229 * Cancel any possible reconnect timeouts when we start the
2230 key exchange. Affected file silcd/server.c.
2232 * Do not reconnect on connection failure when SCONNECT was
2233 given. Affected files silcd/server.[ch].
2235 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2237 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2239 * Fixed the NICK command to always give the unformatted
2240 nickname to the one giving the NICK command. If unformatted
2241 nickname is cached already it will be formatted and the
2242 local entry will always get the unformatted nickname.
2243 Affected file lib/silcclient/idlist.c.
2245 * Fixed some double frees from client library commands.
2246 Affected file is lib/silcclient/command.c.
2248 * Fixed CUMODE command in server to assure that no one can
2249 change founder's mode than the founder itself, there was a
2250 little bug. Affected file silcd/command.c.
2252 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2254 * Removed the SilcClientCommandDestructor from the client
2255 libary, it is not needed anymore. Affected files are
2256 lib/silcclient/silcapi.h, command[_reply].[ch],
2257 client_notify, idlist.c.
2259 * Fixed GETKEY command to first resolve client, and then
2260 resolve the server only if the client was not found, instead
2261 of resolving both at the same time. Affected file is
2262 lib/silcclient/command.c.
2264 * Added silc_client_start_key_exchange_cb and lookup the
2265 remote hostname and IP address before starting the key
2266 exchange with server. The affected file is
2267 lib/silcclient/client.c.
2269 * The server's public key is now saved using the IP address
2270 of the server and not the servername for the filename.
2271 The hostname public key filename is checked as an fall back
2272 method if the IP address based filename is not found.
2274 Fixed the GETKEY command to save the fetched server key
2275 in correct filename.
2277 Print the remote server's hostname now when new key is
2278 received during connection process. Affected file is
2279 irssi/src/silc/core/client_ops.c.
2281 * Return always our own public key to the client if it asks
2282 for it with GETKEY command. Affected file silcd/command.c.
2284 * Removed the use_auto_addr variable from default config
2285 file since it was in wrong section. Affected file is
2288 * Fixed TOPIC_CHANGE notification to not route it when it
2289 was sent using silc_server_send_notify_to_channel function.
2290 Affected file silcd/command.c.
2292 * Fixed silc_server_send_notify_kicked to send the kicker's
2293 Client ID also, it was missing. Affected files are
2294 silcd/command.c, silcd/packet_send.[ch].
2296 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2298 * Do not save client history information in SERVER_SIGNOFF.
2299 Fixes the bug in normal server that it does not detect
2300 the client becoming valid after the server becomes back
2301 online. Affected file silcd/server_util.c.
2303 * Added `sock_error' field into the SilcSocketConnection
2304 context. When error occurs during socket operation (read
2305 or write) the error is saved. Added also new function
2306 silc_socket_get_error to return human readable socket error
2307 message. Affected files are lib/silcutil/silcsockconn.[ch],
2308 lib/silcutil/unix/silcunixsockconn.c, and
2309 lib/silcutil/win32/silcwin32sockconn.c.
2311 * The server now prints the socket error message in the
2312 signoff for client. Affected file silcd/server.c.
2314 * Fixed the `created' channel information sending from router
2315 to server in JOIN command. Checks now whether the channel
2316 really was created or not and set it according that.
2318 Fixed the JOIN command to use the client entry's current
2319 ID during the joining procedure instead of the one it sent
2320 in the command (it is checked though), since it can change
2321 between the packet processing and command processing, and
2322 would just case unnecessary pain in the client end. Affected
2323 file silcd/command.c.
2325 * Fixed a channel key payload sending to use correct channel
2326 ID when the server was forced to change the channel's ID by
2327 router. Router sent the key payload with the old Channel ID.
2328 Affected file silcd/packet_receive.c.
2330 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Call silc_server_save_channel_key only if the key payload
2333 was provided in the JOIN command's command reply. Affected
2334 file silcd/command_reply.c.
2336 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2338 * Fixed silc_mp_sizeinbase to return the value correctly with
2339 MPI. Affected file lib/silcmath/mp_mpi.c.
2341 * Fixed the stop_server signal to correctly stop the scheduler
2342 and gracefully stop the server when SIGTERM or SIGINT signals
2343 are received. Affected file silcd/silcd.c.
2345 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2347 * Simple handling of TERM and HUP signals. Also added some log
2348 flushing call around. Affected file is
2351 * Fixed small bugs in silclog.c. Now buffering output will take
2352 effect after 10 seconds since startup: This will ensure that
2353 no important startup messages are lost. Also output redirection
2354 will preserve original format ([Date] [Type] message).
2355 Affected file is lib/silcutil/silclog.c.
2357 * Added two options to the config file, in the logging section:
2358 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2359 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2361 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Do not print the warning about log files not being initialized
2364 more than once to avoid excess logging. Affected file is
2365 lib/silcutil/silclog.c.
2367 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2368 the SIM copying in make install in Makefile.am.pre.
2370 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2372 * Rewritten silclog APIs. Globally interesting changes follows:
2373 silc_log_set_files() changed to silc_log_set_file().
2374 silc_log_set_callbacks() changed to silc_log_set_callback().
2375 ROBOdoc documented silclog header file.
2376 SilcLogCb now returns bool to wether inihibit the default
2377 handler or not (to keep the old behaviour return always TRUE).
2378 The new APIs should also fix the problem of the
2379 silcd_error.log file that was written in the current directory.
2382 Log files streams will remain opened after silc_log_set_file()
2383 call, means less CPU usage notably on high traffic servers.
2384 File streams are now full buffered, and flushed to the disk
2385 every 5 minutes, lesses HD activity and CPU usage.
2386 Messages can be redirected, allowing admins to configure
2387 one single logfile for all server messages.
2388 the silc_log_quick global variable to activate fast-logging.
2389 Affected files lib/silcutil/silclog.[ch]
2391 * Changed some code to conform new silclog APIs. Affected
2392 files are doc/example_silcd.conf.in, silcd/server.c
2393 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2396 * Fixed a memory leak that could occur in some situations.
2397 Affected file silcd/serverconfig.c.
2399 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2401 * Added the silc_client_del_client to remove the client from
2402 all channels as well. Affected file lib/silcclient/idlist.c.
2404 * Fixed the client library to correctly remove the client
2405 from all channels when the client entry is being destroyed.
2406 Affected file lib/silcclient/client_notify.c, command.c.
2408 * Added auto-nicking support to the client library. If the
2409 applicatio now sets client->nickname it will be sent to the
2410 server after connecting by the library. This way for example
2411 SILCNICK (or IRCNICK) environment variables will have effect
2412 and always change the nickname automatically to whatever
2413 it is wanted. Affected file lib/silcclient/client.[ch].
2415 * Renamed silc_server_command_bad_chars to the
2416 silc_server_name_bad_chars and moved it to the
2417 silcd/server_util.[ch]. Added also new function
2418 silc_server_name_modify_bad to return nickname that
2419 includes bad characters as new nickname without those
2420 bad characters. This check and modify is now used in
2421 silc_server_new_client when the username is initially set
2422 as nickname, so it must be checked to be valid nickname.
2423 Affected file silcd/packet_receive.c.
2425 * The nickname length is now taken from the packet for real
2426 and not trusted to strlen() since it clearly can return
2427 wrong length for nickname including bad characters. This
2428 also applies to channel names. Affected file silcd/command.c.
2430 * Removed the lib/silcsilm/modules directory. Modules are now
2431 compiled into the lib/silcsim. Fixed the copying of the
2432 modules to follow symbolic links in Makefile.am.pre.
2434 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2436 * Fixed silc_string_regexify list creation. Fixes bugs with
2437 BAN and INVITE commands in server. The affected file is
2438 lib/silcutil/unix/silcunixutil.c.
2440 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Removed the command destructor entirely from the server's
2443 command and command reply routines. It is not needed, and
2444 its usage was buggy and caused crashes. Affected files are
2445 silcd/command[_reply].[ch].
2447 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Cancel protocol and NULL sock->protocol if timeout
2450 occurred during protocol. Affected file silcd/server.c.
2452 * Cancel protocol timeouts always before calling the final
2453 callback, to assure that after final callback is called
2454 no other state will be called for the protocol anymore.
2455 Affected file silcd/protocol.c.
2457 * Print error log if incoming connection configuration could
2458 not be found. Affected file silcd/server.c.
2460 * Fixed JOIN command to correctly save the founder mode
2461 to the client on normal SILC server, when the channel
2462 was created by the router. Affected file silcd/command.c.
2464 * Fixed LIST command (hopefully) to send correct reply
2465 packets. Affected file silcd/command.c.
2467 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * The silc_packet_receive_process now returns FALSE if the
2470 read data was invalid packet, and TRUE if it was ok.
2472 The server now checks that if unauthenticated connection
2473 sends data and its processing fails the server will close
2474 the connection since it could be a malicious flooder.
2476 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2478 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Make sure the warning about error opening a log file is
2481 printed only once and not everytime it fails (produces
2482 too much useless log). Affected file lib/silcutil/silclog.c.
2484 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2486 * Made the silc_server_daemonise() function more readable.
2487 Affected file silcd/server.c.
2489 * Pid file is now optional, the user may comment it out from
2490 the config file. Removed define SILC_SERVER_PID_FILE, we
2491 don't need a default any longer. Affected file
2492 configure.in.pre, lib/Makefile.am.pre.
2494 * Make some use of the pid file. The server now dies at startup
2495 if it detects a valid pid file on his path. The server would
2496 die anyway in this circumstance, because of the bind() failure.
2497 Affected file silcd/silcd.c.
2499 * No longer compiling lib/dotconf.
2501 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Fixed JOIN command parsing not to crash. Affected file
2504 lib/silcclient/command.c.
2506 * Fied the NICK_CHANGE notify to add the new client entry
2507 even it is resolved. This removes an <[unknown]> nick
2508 thingy bug in the client. Affected file is
2509 lib/silcclient/client_notify.c.
2511 * Do not try to allocate 0 bytes (efence does not like it)
2512 in lib/silccore/silccomand.c when encoding payload.
2514 * Do not take IRCNICK as nickname in Irssi SILC client since
2515 it is not possible to set nickname before hand connecting
2516 the server (TODO has an entry about adding auto-nicking
2519 * Changed the silc_server_command_pending to check whether
2520 there already exists an pending entry with the specified
2521 command, command identifier and pending callback. This is
2522 to fix IDENTIFY and WHOIS related crashes that may register
2523 multiple pending commands with same identifier. Affected
2524 file silcd/command.c.
2526 * Fixed the server to reconnect to the router even if it
2527 was already reconnecting and EOF was received. This to
2528 fix a possibility that the server wouldn't ever try to
2529 auto-reconnect to the router. Affected file silcd/server.c.
2531 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Fixed the server's password authentication to use the
2534 length of the locally saved password, and not the one
2535 sent in the packet. Affected file silcd/protocol.c.
2537 * Fixed same password authentication problem in the
2538 Authentication Payload handling routines in
2539 lib/silccore/silcauth.c.
2541 * Yet another password authentication problem fixed with
2542 channel password handling in silcd/command.c.
2544 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * If first character of string in silc_parse_userfqdn is '@'
2547 then do not parse it. Affected file is
2548 lib/silcutil/silcutil.c.
2550 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Fixed minor bug in IDENTIFY command reply sending, which
2553 caused various weird problems during JOIN when it was
2554 resolving names for users. Affected file silcd/command.c.
2556 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Fixed the IDENTIFY command reply sending to chech better valid
2559 clients. It was possible to send incomplete list of replies.
2560 Affected file silcd/command.c.
2562 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Added silc_client_command[s]_[un]register functions now to
2565 dynamically register the commands in client library. Removed
2566 the static table of commands. This allows the client library
2567 to call commands without causing the application to know about
2568 what commands library has called.
2570 Removed the INFO command reply kludge to detect when the command
2571 was called by library. Now library use its own command reply
2572 function for INFO command.
2574 Added function silc_client_command_call to call a command.
2575 Application can use it to call command, not access the structure
2578 Now all commands that are sent by the client library (not
2579 explicitly sent by application) use own command reply functions.
2581 Affected files around lib/silcclient/ and in
2582 irssi/src/silc/core/.
2584 * Fixed the WHOIS command reply sending to chech better valid
2585 clients. It was possible to send incomplete list of replies.
2587 Fixed the WHOIS and IDENTIFY to send the request to router
2588 if normal server did not do it and did not find any results.
2590 Affected file silcd/command.c.
2592 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Moved the internal data from SilcClient context into its
2595 own file, not accesible to application. Affected files
2596 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2597 and other files in client library.
2599 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Added doc/examples installation target in Makefile.am.pre.
2604 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2607 commands the found client entry will be removed from the
2608 cache, after notifying application about the error. Affected
2609 file lib/silcclient/command_reply.c.
2611 * Changed the /MSG to check for exact nickname user gave, and
2612 not let `nick' match `nick@host' if it is only one found. Now,
2613 user must type the exact nickname (like nick@host2) even if
2614 there are no more than one same nicks found. This is to avoid
2615 a possibility of sending nickname to wrong nickname since
2616 `nick' could match `nick@host'. Affected file is
2617 irssi/src/core/silc-servers.c.
2619 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Do not print "you are now server operator" or similar when
2622 giving /away command. Affected files are
2623 irssi/src/silc/core/client_ops.c, silc-servers.h.
2625 * Made the silc_server_command_pending_error_check to send
2626 the same command reply payload it received back to the
2627 original sender of the command. This way all arguments
2628 that was received by the server will be received by the
2629 client too. Affected file silcd/command.c.
2631 * Added the silc_idcache_add to return the created cache entry
2632 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2634 * Add global clients to expire if they are not on any channel.
2635 This is because normal server will never know if they signoff
2636 if they are not on any channel. The cache expiry will take
2637 case of these entries. This is done by normal servers only.
2638 The affected files are silcd/command_reply.c,
2639 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2641 * If server receives invalid ID notification for WHOIS or
2642 IDENTIFY and the ID exists in the lists, it is removed.
2643 Affected file silcd/command_reply.c.
2645 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2646 in client then client entry that it matches is searched and
2647 the nickname is printed on the screen for user. Affected
2648 file irssi/src/silc/core/client_ops.c.
2650 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Use cache entry expire time in the LIST command reply to
2653 purge old entries from the cache after the LIST command
2654 reply has been received. This way we don't have non-existent
2655 entries in the cache for too long. Affected file is
2656 silcd/command_reply.c.
2658 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * If we are normal server, and we've not resolved client info
2661 in WHOIS or IDENTIFY from router, and it is global client,
2662 we'll check whether it is on some channel. If it is not
2663 then we cannot be sure about its validity and will resolve it
2664 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2665 file silcd/command.c.
2667 * Search channel by name (if possible) rather than by ID
2668 in IDENTIFY command's command reply. Affected file is
2669 silcd/command_reply.c.
2671 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2674 Updated specs and implemented it. Affected file silcd/command.c,
2675 silcd/packet_send.c and silcd/packet_receive.c.
2677 * Implemented the <founder auth> payload handling in the JOIN
2678 command. If provided all conditions for channel joining
2679 except requirement to provide correct passphrase can be
2680 overrided by the channel founder. Updated the protocol specs.
2681 Affected file silcd/command.c.
2683 Added support for founder auth in JOIN command in client
2684 library. Fixed the parsing of the JOIN command now to support
2685 all options as they should be. The affected file is
2686 lib/silcclient/command.c.
2688 * Optimized the WHOIS and IDENTIFY commands to send the request
2689 to router only if it includes nicknames or other names. If
2690 they include only IDs then check the local cache first before
2691 routing. Affected file is silcd/command.c.
2693 * Added channels topic announcements. Affected file is
2694 silcd/packet_receive.c and silcd/server.c.
2696 * Fixed the silc_server_send_notify_topic_set to really destine
2697 the packet to channel. Affected file silcd/packet_send.c.
2699 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2700 library. Affected file lib/silcclient/client_notify.c.
2702 * Added UMODE announcements. Affected file silcd/server.c.
2704 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Memory leak fixes in:
2708 lib/silcutil/silcsockconn.c
2709 lib/silcske/silcske.c
2710 lib/silcske/groups.c
2712 lib/silccrypt/silcpkcs.c
2713 lib/silccore/silccommand.c
2714 lib/silccore/silcidcache.c
2719 * ROBOdoc documented the lib/silcske/groups.h file and a
2720 bit changed the interface for better.
2722 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2724 * Update the client entry context in the ID cache after
2725 nick change. Affected file lib/silcclient/command.c.
2726 Fixes the CUMODE command when regaining founder privileges,
2727 and a little WHOIS problem.
2729 * Fixed silc_net_gethostbyname to correctly call the
2730 inet_ntop. Affected file lib/silcutil/silcnet.c.
2732 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2734 * Added IPv6 support checking to the configure.in.pre, added
2735 also --enable-ipv6 option to override the check. Affected
2736 file configure.in.pre.
2738 * The silc_thread_create now calls the start function
2739 directly if threads support is not compiled in. Removes
2740 ugly #ifdef's from generic code. Affected files are
2741 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2743 * Added silc_net_gethostby[name/addr]_async to asynchronously
2744 resolve. Affected files are lib/silcutil/silcnet.[ch].
2746 * Added support for rendering IPv6 based server, client and
2747 channel IDs. Affected file lib/silcutil/silcutil.c.
2749 * Added support for creating IPv6 based server IDs. Affected
2750 file is silcd/serverid.c.
2752 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2754 * Added silc_net_gethostby[addr/name] into the
2755 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2756 routines. Added silc_net_is_ip[4/6]. Affected file is
2757 lib/silcutil/unix/silcunixnet.c. All routines that take
2758 address as argument now supports both IPv4 and IPv6 addresses.
2760 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2762 * Fixed LIST command reply sending in server. Affected file
2765 * Server now sends the kicker's client ID in the KICK notify
2766 to the kicked client. Affected file silcd/command.c.
2768 * The client library now parses the kickers client ID and
2769 UI displays it. Affected files lib/silcclient/client_notify.c
2770 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2772 * Made all payload parsing function prototypes consistent.
2773 They all take now const unsigned char * and uint32 pair as
2774 the payload data instead of SilcBuffer. Changes all around
2775 the source tree. Other unsigned char* -> const unsigned char*
2776 changes around the tree as well.
2778 * Optimized SFTP client and server packet sending not to
2779 allocate new buffer for each packet but to recycle the
2780 first allocated buffer. Affected files are
2781 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2783 * Optimized the SFTP client to use SilcList instead of
2784 SilcDList for requests, because it is faster. Affected file
2785 is lib/silcsftp/sftp_client.c.
2787 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2788 into lib/silccore/silcid.[ch].
2790 Renamed silcpayload.[ch] into silcargument.[ch].
2792 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * If client entry is deleted with active key agreement
2795 session, abort the session.
2797 The silc_client_abort_key_agreement now calls the completion
2798 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2800 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2803 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Don't use __restrict in older GCC's. Affected file is
2806 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2808 * silc_net_localhost now attempts to reverse lookup the
2809 IP/hostname. Affected file lib/silcutil/silcnet.c.
2811 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2812 command. It can be used to gain founder privileges at
2813 the same time when joining the channel.
2815 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2816 kicker's client ID as well. Updated protocol specs.
2818 Defined that the server must send SILC_COMMAND_IDENTIFY
2819 command reply with error status to client who sent
2820 private message with invalid client ID.
2822 Updated the protocol specification.
2824 * Added silc_server_send_command_reply to send any
2825 command reply. Affected file silcd/packet_send.[ch].
2827 * Added silc_id_payload_encode_data to encode ID payload
2828 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2830 * The server now send IDENTIFY command reply with error
2831 status if client ID in private message is invalid. Affected
2832 file silcd/packet_receive.c.
2834 * Save the server key file with server's IP address in
2835 the filename instead of hostname. The affected file is
2836 irssi/src/silc/core/client_ops.c.
2838 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2843 * Added libtool support for compiling shared objects in
2844 lib/silcsim. Affected file configure.in.pre and
2845 lib/silcsim/Makefile.am. Original patch by cras.
2847 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2849 * Pid file configuration, and server's config file fixes
2850 patch by toma. Updated CREDITS file.
2852 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Fixed silc_client_channel_message to not try to decrypt
2855 the message twice if it resolved the destination client
2856 information. This could cause of dropping one channel
2857 message. Affected file lib/silcclient/client_channel.c.
2859 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2862 lib/silcclient/client.c. This function is used when the SILC
2863 Client is run under some other scheduler, or event loop or
2864 main loop. On GUI applications, for example this may be
2865 desired to used to run the client under the GUI application's
2866 main loop. Typically the GUI application would register an
2867 idle task that calls this function multiple times in a second
2868 to quickly process the SILC specific data.
2870 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2872 * Fixed silc_server_drop() for dropping the supplementary
2873 groups as well, this could cause a security hole on some
2876 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2881 * Write PID file after dropping privileges. Added -F option
2882 to run server on foreground. A patch by debolaz.
2883 Affected files silcd/server.c, silcd/silcd.c.
2885 * Fixed MOTD to return the MOTD file server name. Affected
2886 file silcd/command.c.
2888 * Added INFO command reply handling to the Irssi SILC Client.
2889 Affected file irssi/src/silc/core/client_ops.c.
2891 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Fixed the silc_idcache_list_* routines to really support
2894 the dynamic list. Fixes a crash. Affected file is
2895 lib/silccore/silcidcache.c.
2897 * Fixed the LIST command reply to really call LIST command's
2898 pending callbacks. Affected file silcd/command_reply.c.
2900 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Update conn->local_entry->nickname after giving NICK
2903 command. Affected file lib/silcclient/command.c.
2905 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2907 * Added the [pid] option to the silcd configuration file
2909 Affected files: serverconfig.[ch] and silcd.c
2911 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Save fingerprint in WHOIS command reply in server.
2914 Affected file silcd/command_reply.c.
2916 * Fixed NICK commands pending callback registration.
2917 Affected file lib/silcclient/command.c.
2919 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Use ++server->cmd_ident when sending commands in server,
2922 instead of random number. Affected file silcd/command.c.
2924 * Fixed GETKEY command reply to call actually GETKEY pending
2925 command callbacks. Affected file silcd/command_reply.c.
2927 * A bit stricter check for nicknames. Check for same nickname
2928 in NICK command also. Affected file silcd/command.c.
2930 * Do not call INFO command everytime client ID changes, only
2931 during first connecting. Affected file lib/silcclient/client.c.
2933 * Set the new nickname only after successful command reply for
2934 NICK command is returned by server. Affected file
2935 lib/silcclient/command.c.
2937 * Remove nicknames from nicklist during server_signoff notify.
2938 Should fix /NAMES bit more. The affected file is
2939 irssi/src/silc/core/silc-channels.c.
2941 * Added `fingerprint' field to the SilcIDListData in the
2942 silcd/idlist.h to hold the fingerprint of the client's
2945 Send the fingerprint of the client's public key in WHOIS
2948 Affected files silcd/command.c, and silcd/idlist.[ch].
2950 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2951 create fingerprint from given data.
2953 * Show the fingerprint of the client's public key in WHOIS.
2954 Affected files irssi/src/module-formats.[ch] and
2955 irssi/src/silc/core/client_ops.c.
2957 * Format the multiple same nicknames also during JOIN and
2958 NICK_CHANGE notifys. Affected file is
2959 lib/silcclient/client_notify.c.
2961 * Do not print error on screen for invalid private message
2962 payload since it can come if someone is sending private
2963 messages with wrong key. Affected file
2964 lib/silccore/silcprivate.c.
2966 * Fixed multiple concurrent /PING crash. Affected file
2967 lib/silcclient/command.c.
2969 * Changed the wrong ID encoding. All IP addresses must be
2970 in MSB first order in encoded format. They were encoded
2971 wrong and was in LSB format. Affected files are
2972 silcd/serverid.c, lib/silcutil/silcutil.c.
2974 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2976 * Call the `connect' client operation through the scheduler
2977 in case of error. Affected file lib/silcclient/client.c.
2979 * Call the `failure' client operation even if the error
2980 occurred locally during a protocol. Affected file is
2981 lib/silcclient/protocol.c.
2983 * Added support of sending LIST command to router from normal
2984 server. This way normal server can get list of all channels
2985 in the network too. Fixed the channel list sending in the
2986 server too. Affected files are silcd/command.c, and
2987 silcd/command_reply.[ch].
2989 * Added silc_server_update_channels_by_server and
2990 silc_server_remove_channels_by_server. They are used during
2991 disconnection of primary router and in backup router protocol.
2992 Affected file silcd/server_util.[ch], silcd/server.c and
2993 silcd/server_backup.c.
2995 * Fixed channel adding to global list in IDENTIFY command
2996 reply in server. Affected file silcd/command_reply.c.
2998 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * If the incoming packet type is REKEY or REKEY_DONE process
3001 that packet always synchronously. Fixes yet another MAC
3002 failed error on slow (dialup) connections. Affected file
3003 lib/silcclient/client.c and silcd/server.c.
3005 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Call check_version SKE callback for initiator too. Affected
3008 file lib/silcske/silcske.c.
3010 * Implemented fix for security hole found in the SKE that was
3011 fixed in the specification few days back; the initiator's
3012 public key is now added to the HASH value computation.
3013 Added backwards support for the old way of doing it too, for
3014 old clients and old servers. Affected file is
3015 lib/silcske/silcske.c.
3017 * Enabled mutual authentication by default in SKE. If initiator
3018 is not providing mutual authentication the responder will
3019 force it. This will provide the proof of posession of the
3020 private key for responder. The affected files are
3021 lib/silcclient/protocol.c and silcd/protocol.c.
3023 * Do not cache anymore the server's public key during SKE.
3024 We do mutual authentication so the proof of posession of
3025 private key is done, and if the server is authenticated in
3026 conn auth protocol with public key we must have the public
3027 key already. Affected file silcd/protocol.c.
3029 * Added new global debug variable: silc_debug_hexdump. If
3030 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3031 file lib/silcutil/silclog.[ch].
3033 * Fixed compilation warning due to char * -> const char *.
3034 Affected files lib/silcutil/silcnet.h, and
3035 lib/silccore/silcauth.[ch].
3037 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Fixed CMODE command when new channel key was created. If
3040 the creation failed the old key was removed. Next time giving
3041 same command would crash the server since the old key was
3042 freed already. Affected file silcd/command.c.
3044 * Fixed the silc_server_announce_get_channels to not crash
3045 on reconnect. Affected file silcd/server.c.
3047 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Added silc_log_set_debug_string function to set a regex
3050 string to match for debug output. Only the function names,
3051 or filenames matching the given debug string is actually
3052 printed. This way it is possible to filter out those debug
3053 strings that user is not interested in.
3055 Fixed a bug in silc_string_regexify.
3057 Affected files lib/silcutil/silclog.[ch], and
3058 lib/silcutil/unix/silcunixutil.c.
3060 * Changed the -d options in both server and Irssi SILC client
3061 to take the debug string as argument. Affected files
3062 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3064 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Added silc_hash_babbleprint to create a Bubble Babble
3067 Encoded fingerprint. The encoding is developed by Antti
3068 Huima (draft-huima-babble-01.txt), and it creates human
3069 readable strings out of binary data. Affected file
3070 lib/silccrypt/silchash.[ch].
3072 * Print the babble print now in addition of fingerprint as well
3073 in Irssi SILC client. Affected files are
3074 irssi/src/fe-common/silc/module-formats.[ch],
3075 irssi/src/fe-common/silc/core/client_ops.c.
3077 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Fixed a security problem found in SKE. The initiator's
3080 public key too is now added to the HASH hash value creation
3081 which is signed by the responder to create the SIGN value.
3082 This will prevent anyone in the middle to lie to the responder
3083 about the initiator's public key. If this is done now, the
3084 man in the middle will get caught. Updated the protocol
3087 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Better installation directory handling. Configure module
3090 paths and other paths automatically to example_silc* files
3091 in doc/. A patch by toma.
3093 * Fixed compiler warning from MPI library, and from SILC RNG.
3096 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3097 It can be configured with ./configure. A patch by toma.
3099 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Find correct make to use in prepare-clean. A patch by
3102 toma. Affected file prepare-clean.
3104 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3106 * Added irssi variables use_auto_addr, auto_bind_ip,
3107 auto_bind_port and auto_public_ip.
3109 * Changed the interface for silc_client_send_key_agreement
3110 in lib/silcclient/silcapi.h
3114 irssi/src/silc/core/silc-core.c
3116 lib/silcclient/silcapi.h
3117 irssi/src/silc/core/silc-channels.c
3118 lib/silcclient/client_keyagr.c
3121 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3123 * Added silc_pkcs_public_key_compare to compare two
3124 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3126 * Check that the client who set the founder mode on the
3127 channel is the same client that is giving the founder
3128 mode to itself. It is done by comparing the saved public
3129 key (it is saved even in the authentication is passphrase).
3130 Affected file silcd/command.c.
3132 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Do not process packet for disconnected socket connection.
3135 Affected file lib/silccore/silcpacket.c.
3137 * Process the DISCONNECT packet through scheduler in the
3138 client library. Affected file lib/silcclient/client.c.
3140 * Fixed the silc_client_packet_parse to not to increase
3141 the packet sequence number if the conn->sock and the
3142 current socket connection is not same. This can happen
3143 for example during key agreement when the conn includes
3144 multiple socket connections (listeners). Affected file
3145 lib/silcclient/client.c.
3147 * The sender of the file transfer request now provides also
3148 the pointer (listener) for the key exchange protocol. If
3149 the listener cannot be created then it sends empty key
3150 agreement and lets the receiver provide the listener.
3152 Added `local_ip' and `local_port' arguments to the
3153 silc_client_file_send. If they are provided they are used,
3154 if not then it will attempt to find local IP address, if
3155 not found or bind fails then the remote client will provide
3158 Affected files are lib/silcclient/client_ftp.c and
3159 lib/silcclient/silcapi.h.

3234 preserve the WHOWAS info for the client. Affected file
3235 silcd/server_util.c.
3237 * Fixed SERVER_SIGNOFF notify handling in the server. The
3238 server is now able to process incoming SERVER_SIGNOFF notify
3239 for a server that it doesn't even know about. It will remove
3240 the clients provided in the notify. Affected file
3241 silcd/packet_receive.c.
3243 * Check for partial packet in data queue after every packet that
3244 was found from the queue. Return and wait for more data if
3245 there is partial data in queue. Affected file is

3263 irssi/src/fe-common/silc/module-formats.[ch].
3265 * Wrote a help file for FILE command.
3267 * Added silc_rng_global_get_byte_fast to get not-so-secure
3268 random data as fast as possible. Random data is read from
3269 /dev/urandom if available and from the SILC RNG if not
3270 available. It is used in padding generation. Affected file
3271 lib/silccrypt/silcrng.[ch].
3273 * All packets in client library are now processed synchronously.
3274 Optimized packet processing a lot. Affected file
3275 lib/silcclient/client.c.

3286 * Assure that silc_client_notify_by_server_resolve does not
3287 resolve the client information multiple times. If it cannot
3288 be found by the first it cannot be found at all. Affected
3289 file lib/silcclient/client_notify.c.
3291 * Fixed WHOWAS command reply calling. Affected file
3292 lib/silcclient/command_reply.c.
3294 * Removed all references to silc_idlist_get_client from the
3295 Irssi SILC client since that call is internal call used by
3296 the library. The Irssi SILC client will use now client
3297 retrieval functions found in silcapi.h.
3299 * Fixed a bug in resolving nickname info before sending
3300 private message. It used freed memory. Affected file
3301 irssi/src/silc/core/silc-servers.c.
3303 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Assure my_channels statistics cannot go negative in server.
3306 Affected files silcd/server.c, silcd/server_util.c.

3322 * Added silc_net_localip to return local host's IP address.
3323 Affected file lib/silcutil/silcnet.[ch].
3325 * If key exchange or rekey protocol is active for a connection
3326 parse all packets syncronously since there might be packets
3327 in packet queue that we are not able to process without first
3328 processing packets before them. Affected file silcd/server,
3329 lib/silcclient/client.c.
3331 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3332 whether library should continue processing the packet.
3333 Affected file lib/silccore/silcpacket.h.

3379 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3380 is incomplete and is being resolved, it won't be resolved
3383 Make sure also that USERS command reply does not resolve
3384 twice information. Affected file is
3385 lib/silcclient/command_reply.c.
3387 Make sure that silc_client_get_clients_by_list does not
3388 resolve twice same information.
3390 * Check for valid client->id in the silc_server_free_client_data.
3391 Affected file silcd/server.c.
3393 * Fixed /GETKEY nick@server not to crash if the server entry
3394 is not found. Affected file lib/silcclient/command.c.
3396 * Fixed the silc_server_check_cmode_rights to check the
3397 requested modes correctly. Affected file silcd/command.c.

3402 Affected file silcd/command.c.
3404 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3406 * Call the silc_server_udpate_servers_by_server in the
3407 primary router that comes back online in the backup resuming
3408 protocol. Otherwise it routes packets wrong. Affected file
3409 silcd/server_util.[ch], silcd/server_backup.c.
3411 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3414 lib/silcutil/silcbuffmt.[ch].
3416 * Redefined the SILC packet header to include the padding
3417 length. Affected file lib/silccore/silcpacket.[ch].
3419 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3420 length for maximum padding up to 128 bytes). Affected
3421 file lib/silccore/silcpacket.h.
3423 * Removed all backwards support for old 0.5.x MAC thingies.
3424 The SILC packet header change makes it impossible to be
3425 backwards compatible.
3427 * Send the ENDING packet with timeout in the backup resuming
3428 protocol. This is to assure that all routers has connected
3429 to the primary router. Affected file silcd/server_backup.c.
3431 * Changed the RNG to take the first IV from random data. It
3432 used to take it from zero actually. Changed the RNG also
3433 to use /dev/urandom during session. /dev/random is used
3434 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3436 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Changed the SILC packet header to have the first two bytes
3439 (the packet length) encrypted. Affected files aroung the
3440 code tree, lib/silccore/silcpacket.[ch]. Removed the
3441 SilcPacketCheckDecrypt callback. It is not needed anymore
3442 since the silc_packet_receive_process will determine now
3443 whether the packet is normal or special.
3445 * Implemented the unidirectional MAC keys. Affected files
3446 lib/silcske/silcske.c, silcd/protocol.c and
3447 lib/silcclient/protocol.c.
3449 * Implemented the packet sequence number to the MAC computation.
3450 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3451 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3452 lib/silcclient/protocol.c.
3454 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Allow backup router to announce servers. All servers
3457 announced by backup router are added to the global list
3458 automatically. Update hte server's socket to our primary
3459 router also when backup router announces a server.
3460 Affected file silcd/packet_receive.c.
3462 * Do not update the client->router in the function
3463 silc_server_udpate_clients_by_server if the client is on
3464 global list. We might fail to find any specific server
3465 for locally connected clients and local cell clients. They
3466 should still use the `from' and not `to' as client->router.
3467 This fixes backup router resuming protocol. Affected file
3468 silcd/server_util.c.
3470 * Decrease channel statistics count only if the channel
3471 deletion worked. Affected files are silcd/server.c and
3472 silcd/server_util.c.
3474 * Added silc_server_update_servers_by_server to update origin
3475 of all server entries. Used during backup router protocol.
3476 Affected files silcd/server_util.[ch], silcd/server.c. and
3477 silcd/backup_router.c.
3479 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3480 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3481 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3482 lib/silccrypt/silchmac.c.
3484 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Assure that router cannot reroute the same channel message
3487 to the sender. Affected file silcd/packet_receive.c.
3489 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Made better checks that the channel message is not sent
3492 to the router it came from. Affected file is
3493 silcd/packet_send.c. Fixed memory leak too.
3495 * Announce informations for incoming router connection, but
3496 only after checking if it is replaced by backup router.
3497 Affected file silcd/packet_receive.c.
3499 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Fixed the backup resuming protocol to work in multiple
3502 router environment. Affected file silcd/server_backup.c.
3504 * Route packet only to one router in the function
3505 silc_server_packet_send_to_channel. Affected file is
3506 silcd/packet_send.c.
3508 * Fixed silc_server_send_notify_dest to set the broadcast
3509 flag. Fixed the silc_server_send_notify_topic to actually
3510 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3511 Affected file silcd/packet_send.c.
3513 * Changed the SFTP Filesystem interface. Changed the
3514 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3515 the filesystem operation function. The SilcSFTPFilesystem
3516 is now a context that is allocated by all filesystem allocation
3517 functions and it already includes the operations structure
3518 and filesystem specific context. It is given as argument
3519 now to the silc_sftp_server_start. This made the interface
3520 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3521 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3523 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Changed the backup router adding and getting interfaces
3526 in the server. The router that will be replaced by the
3527 specified backup router is now sent as argument. Affected
3528 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3531 * Added silc_net_addr2bin_ne to return the binary form of
3532 the IP address in network byte order. Affected files
3533 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3535 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Check for existing server ID in silc_server_new_server
3538 and in silc_server_connect_to_router_final and remove the
3539 old entry if it exists. Affected file silcd/packet_receive.c,
3542 * Send the channel message always to only one router, either
3543 in upstream or downstream. Affected file is
3544 silcd/packet_send.c.
3546 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Wrote the definition of the backup resuming protocol to the
3549 protocol specification.
3551 * Removed one redundant channel key generation from normal
3552 server during joining procedure. Removed one redundant
3553 channel key sending from server to router during joining
3554 procedure. Affected file silcd/command.c.
3556 * Made minor bugfixes to the backup router resuming protocol.
3557 Affected file silcd/server_backup.c, server.c.
3559 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3561 * Added --disable-asm configuration option. Affected files
3562 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3565 * Implemented the backup resuming protocol that is used to
3566 resume the primary router position in the cell after the
3567 primary router comes back online. Affected files
3568 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3569 and silcd/server_util.[ch].
3571 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3573 * Sleep two (2) seconds after sending QUIT command to server.
3574 Affected file lib/silcclient/command.c.
3576 * Assure that if outgoing data buffer is pending do not force
3577 send any data. Affected file silcd/packet_send.c.
3579 * Assure that if outgoing data buffer is pending do not force
3580 send any data. Affected file lib/silcclient/client.c.
3582 * Implemented the backup router support when the primary router
3583 goes down. The servers and routers can now use the backup
3584 router as new primary router without loosing connectivity.
3586 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3589 in the server to indicate disabled entry. All data read
3590 from the connection will be ignored and no data is sent
3591 for entry that is disabled. Affected files are
3592 silcd/idlist.h, silcd/server.c.
3594 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Created SFTP client and server test programs in the
3597 lib/silcsftp/tests directory.
3599 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Implemented memory filesystem (virtual filesystem) for
3602 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3605 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Implemented the SFTP (SSH File Transfer Protocol) to the
3608 lib/silcsftp. It includes SFTP client and SFTP server
3611 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3613 * Moved lib/silccore/silcprotocol.[ch] to the
3614 lib/silcutil library.
3616 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3617 take variable argument list pointer as argument. Affected
3618 file lib/silcutil/silcbuffmt.[ch].
3620 * Added silc_buffer_set function that is used to set data
3621 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3622 Affected file lib/silcutil/silcbuffer.h.
3624 * Changed various routines in the core library to use the new
3625 silc_buffer_set instead of allocating new buffer only for
3628 * Added 64-bit value formatting and unformatting support to the
3629 silc_buffer_[un]format routines. Affected file is
3630 lib/silcutil/silcbuffmt.[ch].
3632 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3633 to includes/bitmove.h.
3635 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * Fixed channel user mode saving in client library. Affected
3638 file lib/silcclient/command[_reply].c.
3640 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3642 * Defined the file transfer to the SILC Protocol. Added
3643 new packet type SILC_PACKET_FTP and defined File Transfer
3644 Payload. The mandatory file transfer protocol is SFTP
3645 (SSH File Transfer Protocol). Affected file in addition
3646 of the internet draft is lib/silccore/silcpacket.h.
3648 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3649 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3650 is used as part of backup router protocol when the primary
3651 router of the cell is back online and wishes to resume
3652 the position as primary router.
3654 * Redefined the MAC generation keys in the protocol. The
3655 same key is not used anymore in both direction. Both
3656 direction will now use different keys for sending and
3657 receiving. This fixes a potential security flaw. This
3658 change causes incompatibilities in the protocol.
3660 * Redefined also the MAC computation from the packet.
3661 An packet sequence number is now added to the MAC
3662 computation. This prevents possible replay attacks against
3663 the protocol. This change too causes incompatibilities
3666 Added `sequence' field to the SilcPacketContext to hold
3667 the current sequence number for the packet.
3669 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * Added `created' field to the SilcIDListData in the file
3672 silcd/idlist.h to indicate the time when the entry was
3675 * Added `created' field to the SilcChannelEntry too. Affected
3676 file silcd/idlist.h.
3678 * Added `creation_time' aguments to all the announcement functions
3679 in the server. If it is provided then only the entries that
3680 was created after the provided time frame are actually
3681 announced. Affected file silcd/server.[ch].
3683 * The protocol says that the Channel ID's IP address must be
3684 based on the router's IP address. Added check for this in
3685 the silc_server_new_channel when processing incoming New Channel
3686 Payload. Affected file silcd/packet_receive.c.
3688 * Print out the correct version with --version in SILC client.
3689 Affected file irssi/src/silc/core/silc-core.c.
3691 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Fixed WHOWAS command to check for completnes of the client
3694 entry always, not just when the command is coming from client.
3695 Affected file silcd/command.c.
3697 * Added new function silc_server_packet_queue_purge to purge the
3698 outgoing data queue to the network. After the function returns
3699 it is guaranteed that the outgoing packet queue is empty.
3700 Affected file silcd/packet_send.[ch].
3702 * Purge the outgoing packet queue in the rekey protocol's final
3703 callback to assure that all rekey packets go to the network
3704 before quitting the protocol. Affected file silcd/server.c.
3706 * Added silc_client_packet_queue_parse as similar function as
3707 in server to the client library. The affected file is
3708 lib/silcclient/client.c.
3710 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Splitted silcd/server.c and created silcd/server_util.[ch]
3713 for utility functions.
3715 * Added new socket flag SILC_SF_DISABLED to indicate that the
3716 connection is open but nothing can be sent to or received from
3717 the connection. Affected file lib/silcutil/silsockconn.[ch].
3718 The checking for disabled socket is checked in the low level
3719 silc_socket_write and silc_socket_read functions.
3721 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Allow only nicknames and channel names that fits into the
3724 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3726 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * When processing JOIN command reply in server check that if
3729 the channel exists in our global list we'll move it the local
3730 list. Affected file silcd/command_reply.c.
3732 * Fixed the check whether client is joined on the channel already
3733 in JOIN command. Affected file lib/silcclient/command.c.
3735 * Fixed the JOIN command reply to check whether the channel
3736 already exists. Affected file lib/silcclient/command_reply.c.
3738 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Added silc_ske_status_string to map the SKE error numbers
3741 to readable strings. The affected files are
3742 lib/silcske/silcske[_status].[ch].
3744 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Do not show the private channels on the WHOIS channel list
3747 as it is not allowed by the protocol. The affected file is
3750 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Assure that the packet length digged from the actual packet
3753 is something sensible in the silc_packet_decrypt_rest_special
3754 in lib/silccrypt/silcpacket.c.
3756 * Free and NULL the allocated pointer in silc_hmac_alloc if
3757 the HMAC allocation fails. The affected file is
3758 lib/silccrypt/silchmac.c.
3760 * Print the selected security properties to the log files in
3761 the server. Affected file silcd/protocol.c.
3763 * Add SKE's reference counter even if calling the completion
3764 callback manually. Otherwise it goes negative, although it
3765 does not cause any problems. The affected file is
3766 lib/silcske/silcske.c.
3768 * Remove the client entry with short timeout after giving the
3769 KILL command. Affected file lib/silcclient/command.c.
3771 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3772 case all found clients are already disconnected (WHOWAS would
3773 found them) in the server. Affected file silcd/command.c.
3775 * Update the last_receive (time of last data received) to be
3776 updated only when received private or channel message so that
3777 the idle time showed in WHOIS makes more sense.
3779 * Added boolean field `valid' in to the SilcClientEntry in the
3780 client library to indicate whether the entry is valid or not.
3781 This fixes the nickname change bug on channel when changing
3782 the nickname to be same than the old (like nick to Nick) the
3783 nickname formatter doesn't set the new nick anymore to Nick@host.
3784 Affected file lib/silcclient/idlist.[ch].
3786 * Now actually fixed the nickname changing on disconnection.
3787 Added new function silc_change_nick to the Irssi SILC Client.
3788 Affected file irssi/src/silc/core/client_ops.c,
3789 irssi/src/silc/core/silc-nicklist.[ch].
3791 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Check that the public key exists in the GETKEY command before
3794 trying to encode it. Affected file silcd/command.c.
3796 * Print some notifications on received public keys with GETKEY
3797 command in the Irssi SILC Client. Affected files are
3798 irssi/src/fe-common/silc/module-formats.[ch],
3799 irssi/src/silc/core/client_ops.c.
3801 * Use IDENTIFY command to resolve the server information in the
3802 GETKEY command instead of INFO command. Affected file
3803 lib/silcclient/command.c.
3805 * All command reply functions in the client library now calls
3806 the pending command reply callbacks even if an error has
3807 occurred. The server has done this a long time and now it was
3808 time to move the client library to this as well. Now all
3809 errors can be delivered back to the pending command reply
3810 callbacks if necessary. Affected files are
3811 lib/silcclient/command[_reply].[ch].
3813 * Change the nickname on disconnection back to the username
3814 because in reconnect the server will enforce it to it anyway.
3815 Affected file irssi/src/silc/core/silc-servers.c.
3817 * Fixed a config file parsing bug in the Irssi SILC client.
3818 Affected file irssi/src/silc/core/clientconfig.c.
3820 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * When printing the channel mode on JOIN, verify that the
3823 channel key and channel's HMAC are valid. Affected file
3824 irssi/src/silc/core/client_ops.c.
3826 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3828 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3829 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3830 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3832 * Removed channel key rekey task deleting from the function
3833 silc_server_save_channel_key. Affected file silcd/server.c.
3834 Added explicit timeout task context instead that is used to
3835 delete the task if we are registering a new task before the
3836 new task has elapsed.
3838 * When channel key rekey occurs the client library now saves
3839 the old channel key for a short period of time (10 seconds) and
3840 is able to use it in case some is still sending channel
3841 messages encrypted with the old key after the rekey. Affected
3842 file lib/silcclient/[idlist.h|client_channel.c].
3844 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * Added check to the silc_server_new_id_real to not accept
3847 new ID if it is the sender's own ID. Affected file is
3848 silcd/packet_receive.c.
3850 * Assure that we do not announce ourself or the one we've
3851 sending our announcements when we're router and are announcing
3852 servers to our primary router. Affected file silcd/server.c.
3854 * Fixed silc_server_command_identify_check_client to assemble
3855 correct WHOIS packet. It send corrupted WHOIS packet and
3856 caused problem with router to router connections. Affected
3857 file silcd/command.c.
3859 Fixed also silc_server_command_whois_check the same way
3860 as for the IDENTIFY command.
3862 * Added new SilcIDListStatus to the server in the SilcIDListData
3863 structure. The status now includes the current status of
3864 the entry (like registered, resolved etc.). Affected file
3865 silcd/idlist.[ch]. Defined a bunch of different status types
3866 as well. This replaced the old boolean registered field as well.
3868 Added resolve_cmd_ident field to the SilcClientEntry structure
3869 too so that if the entry is for example being resolved so
3870 another command may attach to the same pending command reply
3871 without requiring to resolve the same entry again. This concept
3872 should optimize the WHOIS and the IDENTIFY resolving under
3873 heavy load by taking away unnecessary resolving for entries
3874 that are being resolved already.
3876 Added support for adding multiple pending commands for one
3877 command idenfier. Affected file silcd/command[_reply].[ch].
3879 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3880 before deleting the data. Otherwise the hash table will have
3881 freed data in comparison functions. Affected file is
3882 silcd/command_reply.c.
3884 * Fixed silc_idlist_replace_client_id to add the new entry to
3885 the cache with NULL nickname. Otherwise there will be invalid
3886 memory as the nickname after the nickname is freed. Affected
3887 file silcd/packet_receive.c.
3889 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3890 saved into wrong slots because the previous number of entries
3891 was not taken into account. Affected file silcd/idlist.c.
3892 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3894 * If we are router and we receive JOIN notify to a channel that
3895 does not have any users then notified client is marked as the
3896 channel founder, as it is it. The affected file is
3897 silcd/packet_receive.c
3899 * Added to the extended hash table API's table_del_*ext functions
3900 the destructor as argument too, so that the caller can decide
3901 which destructor to use or whether to use destructor at all.
3902 Affected file lib/silcutil/silchashtable.[ch].
3904 * Fixed ID Cache purging. It actually deleted the entries from
3905 the hash table after the data was freed. The hash table ended
3906 up comparing freed memory. The affected file is
3907 lib/silccore/silcidcache.c.
3909 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3911 * Fixed Irssi SILC client's KILL command's HELP syntax.
3913 * The USERS command now resolves the detailed user information
3914 if the userinfo field is missing. Affected file is
3915 lib/silcclient/command_reply.c.
3917 * Do not print error in silc_file_read if the read file does
3918 not exist. Just silently return NULL. Affected file is
3919 lib/silcutil/silcutil.c.
3921 * Fixed the silc_log_output to not wine about NULL filename
3922 and to not create some bogus " " filename. Affected file is
3923 lib/silcutil/silclog.c.
3925 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Fixed various printing bugs on the user interface in the
3928 Irssi SILC Client. Minor changes that were forgotten from
3931 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Fixed the configure.in.pre and the compilation and distribution
3934 environment to support the new autoconf 2.52. That version is
3935 now required to compile the CVS trunk.
3937 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3939 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3940 to generally parse user@fqdn format strings. Affected file
3941 lib/silcutil/silcutil.c.
3943 * Added nickname_format and nickname_force_format fields to the
3944 SilcClientParams structure. The first one defines the format
3945 for the nicknames that the library will enforce if the receives
3946 multiple same nicknames. The second one is boolean value and
3947 can be used to force the library to always enforce the format
3948 to the nicknames regardles whether there are multiple nicknames
3949 or not. This configurable formatting was employed to flexibly
3950 support accessing multiple nicknames from the user interface.
3951 The userinterface can now set the nicknames to what ever format
3952 they prefer. Affected file lib/silcclient/silcapi.h.
3954 Added function silc_client_nickname_format to the file
3955 lib/silcclient/idlist.c. It performs the nickname formatting.
3957 Added new field `hostname´ to the SilcClientEntry context.
3958 It holds the hostname of the client. Affected file is
3959 lib/silcclient/idlist.h.
3961 * Irssi SILC Client sets the nicknames in nick@hostn format.
3962 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3963 irssi/src/silc/core/silc-core.c.
3965 The WHOIS printing now also shows both the real nickname and
3966 the formatted nickname so that user knows how to access the
3967 user if there are multiple same nicknames cached. Affected
3968 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3969 printing formatting too to take the hostname now as a separate
3970 argument. The Affected file is
3971 irssi/src/fe-common/silc/modules-formats.[ch].
3973 * Changed the silc_client_get_clients_local to accept the formatted
3974 nickname as argument. It accepts the real nickname too but the
3975 formatted nickname can be used to find the true entry from
3976 multiple entries. Affected file lib/silcclient/silcapi.h and
3977 lib/silcclient/idlist.c.
3979 * Added nickname_format_parse field to the SilcClientParams.
3980 It is a callback function provided by the application to parse
3981 the nickname out of the formatted nickname string. The library
3982 calls it to get the nickname from the formatted string. Since
3983 the application generally knows better the format of the nickname
3984 string it parses it instead of the library, even though library
3985 encodes the formatted string. If the callback function is not
3986 provided then the library will use the string as is. The
3987 affected file is lib/silcclient/silcapi.h.
3989 * All the nickname strings passed to the client library in
3990 commands are now expected to be formatted nickname strings.
3991 If the command does not support the formatted nickname string
3992 it will assume that the sent string is the actual nickname.
3993 Affected file lib/silcclient/command.c.
3995 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Added public key authentication support to OPER and SILCOPER
3998 commands in the client library. Affected file is
3999 lib/silcclient/command.c.
4001 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4003 * Changed the get_auth_methdod client operation to be asynchronous.
4004 It can be async if the application resolves the authentication
4005 method from the server during the negotiation. Added new
4006 SilcGetAuthMeth completion callback that the application will
4007 call after resolving the authentication method.
4009 Added function silc_client_request_authentication_method that
4010 the application can use to resolve the authentication method
4011 from the server. Added also SilcConnectionAuthRequest callback
4012 that the library will call after the server has replied. The
4013 application can call this function if it does not know the
4014 current authentication method.
4016 Affected files are lib/silcclient/client.c and
4017 lib/silcclient/silcapi.h.
4019 * The Irssi SILC client now automatically resolves the authentication
4020 method incase any configuration information is not present (and
4021 currently there never is). The affected file is
4022 irssi/src/silc/core/client_ops.c.
4024 * Fixed public key authentication from the client library.
4025 Affected file lib/silcclient/protocol.c. Changed also the
4026 protocol specification about the public key authentication in
4027 the connection authentication protocol. The actual data to be
4028 signed is now computed with a hash function before signing.
4030 * Fixed the public key authentication from the server as well.
4031 Affected file silcd/protocol.c.
4033 * Removed the mlock()'s from the memory allocation routines.
4034 Affected file lib/silcutil/silcmemory.c. The ./configure does
4035 not check anymore for the mlock(). Affected file is
4038 * Fixed USERS command in server to allow the execution of the
4039 command for private and secret channels if the client sending
4040 the command is on the channel. Affected file silcd/command.c.
4042 * Fixed silc_client_get_clients_local to return the clients
4043 count correctly. It could return wrong value. Affected file
4044 lib/silcclient/idlist.c.
4046 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4049 types. The assembler optimizations seemed not to like 64-bit
4050 data types. The assmebler optimizations thus are now enabled
4051 also for BSD systems as opposed to only enable them for Linux.
4053 * Do not check for threads at all on BSD systems. Affected
4054 file configure.in.pre.
4056 * Removed -n and -h options from the Irssi SILC Client since
4057 they are not used in silc.
4059 * Fixed the prime generation to assure that the first digit
4060 of the generated random number is not zero since our conversion
4061 routines does not like number strings that starts with zero
4062 digit. If zero digit is seen the random number is regenerated.
4063 This caused some corrupted RSA keys when the zero first digit
4064 was met. Affected file lib/silcmath/silcprimegen.c.
4066 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4068 * Fixed WIN32 configuration in the ./configure script.
4069 Fixed to include xti.h on environments that has it.
4070 Patches by Carsten Ilchmann and andrew.
4072 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4074 * Changed the silc_id_create_client_id to be collision
4075 resistant. It is now assured that there cannot be created
4076 two same client ID's. I suspect that some weird bugs in
4077 the server were actually caused by duplicate Client IDs.
4078 Affected file silcd/serverid.[ch]. A router receiving
4079 new ID now also assures and informs the sending server
4080 if the ID caused collision.
4082 * Changed the silc_id_create_channel_id to also assure that
4083 there are no collisions.
4085 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4087 * Statement about ignoring the Mutual Authentication flag when
4088 performing rekey with PFS was a bit misleading. It is ignored
4089 if it was set in the initial negotiation, it cannot be even
4090 set in the rekey. Fixed in the ke-auth draft. Started the
4091 new versions of the protocol drafts in the doc/.
4093 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4095 * Fixed a bug in silc_client_command_identify_save when saving
4096 new channel information. The channel name was no duplicated
4097 and caused crash on exit. Affected file is
4098 lib/silcclient/command_reply.c.
4100 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4102 * Fixed the getkey command handling in the server. Send just
4103 empty OK reply to the sender if the key could not be fetched
4104 (but everything else was ok, like the key just was not available).
4105 Changed the public key parameter to optional in the protocol
4106 specs so that empty OK reply can be sent. Affected file
4109 Added a message to Irssi SILC client to tell to user if the
4110 server did not return a public key.
4112 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4114 * Fixed a channel key regeneration bug. It registered new
4115 timeout tasks exponentially until all system resources were
4116 used. Affected file silcd/server.c.
4118 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4120 * Added the SILC Document generator to the scripts/silcdoc.
4121 It can be used to generate the Toolkit Reference Manual out
4122 of the source tree. Internally it will also use the RoboDoc
4123 generator now imported in util/robodoc.
4125 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * Added couple of return's in rekey protocol if error orccurred
4128 during the protocol. The execution must be terminated.
4129 Affected file silcd/protocol.c. Also, terminate the protocol
4130 always with timeout.
4132 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * The client's Client ID was created initally from the wrong
4135 nickname (it could have been in format nick@host) in the
4136 silc_server_new_client. Affected file silcd/packet_receive.c
4138 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Added some SILC_LOG_ERROR's to various error conditions
4141 if client could not be added to ID cache. Affected files
4142 silcd/packet_receive.c and silcd/server.c.
4144 * When client's sock->user_data is freed, NULL also the
4145 client->router and client->connection pointers. Added check
4146 for these pointers being NULL to various places around the
4147 code. Affected file silcd/server.c.
4149 * Added client->data.registered == TRUE checks to various
4150 places around the code to assure that unregistered client's
4151 are not handled when it is not allowed. Affected file
4154 * Added `bool registered' fields to all
4155 silc_idlist_[server|client]_get_* routines to indicate whether
4156 the fetched client needs to be registered or not. Affected
4157 file silcd/idlist.[ch].
4159 * Add your own entry as registered to the ID cache in the
4160 server. Affected file server.c.
4162 * Fixed a bug in silc_server_new_server. The SilcServer was
4163 set as the new server's context instead of SilcServerEntry.
4164 This naturally caused some weird bugs.
4166 * Added "updated" field the SilcChannelEntry which indicates
4167 the time since the channel entry was last accessed. This
4168 can be used to determine whether it is necessary to
4169 announce the channel after backup resuming protocol.
4170 Affected files silcd/idlist.[ch].
4172 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4174 * Do not delete the channel rekey task when adding it
4175 for in silc_server_create_channel_key.
4177 * Changed the silc_server_create_channel_key to return
4178 TRUE or FALSE to indicate the success of the channel key
4181 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Fixed MSVC++ project files and added missing files to
4184 Makefiles under win32/.
4186 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Do not add TCP_NODELAY flag if the operating system
4189 does not have it defined. Affected files are
4190 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4192 * Fixed buffer overflow from Irssi SILC Client. Affected
4193 file irssi/src/fe-common/core/themes.c.
4195 * Fixed double free in client library in the file
4196 lib/silcclient/client.c when disconnecting from server.
4198 * Applied double free patch from cras to Irssi SILC client.
4199 Affected files irssi/src/core/[modules/expandos].c
4201 * Fixed the disconnection handling to Irssi SILC Client.
4202 The application must call silc_client_close_connection
4203 in ops->connect client operation in case of failure of
4204 the connection. Affected file is
4205 irssi/src/silc/core/client_ops.c.
4207 * Do not set sock->protocol to NULL in the function
4208 silc_client_close_connection after executing the protocol's
4209 final callback since the sock might not be valid anymore.
4210 Affected file lib/silcclient/client.c.
4212 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4214 * Do not enable SILC_THREADS if the linking with libpthread
4215 did not happen. Affected file configure.in.pre.
4217 * Added notion to protocol specification that server must
4218 verify the sent authentication payload with CMODE when
4219 setting the channel founder key. Implemented it to the
4220 server. Affected file silcd/command.c.
4222 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4224 * Added _EXTRA_DIST SILC distribution variable to the
4225 distributions file. It is used to conditionally add extra
4226 files or directories to the specific distribution. Affected
4227 files ./prepare, Makefile.am.pre and distributions.

4232 * Added README.WIN32 for instructions to compile the Toolkit
4235 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * Fixed a double free in disconnection in the server. Affected
4238 file is silcd/server.c.
4240 * Fixed the lib/silcske/groups.c to work now also with GMP
4241 MP library. The string conversion did not work when using
4242 specific base and the base is indicated in the string as well.
4244 * Created win32/ directory which now includes MSVC++ specific
4245 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4246 It will appear only in the toolkit distribution
4248 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4250 * Changed the key material distribution function in case when
4251 the hash output is too short. The data is now concatenated
4252 a bit differently than it used to. Made the change to the
4253 SKE protocol specification.
4255 * Added better GMP detection to configure.in.pre. A patch
4258 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Fixed a minor bug in SKE that might cause some problem on
4261 some platforms. Affected file lib/silcske/silcske.c.
4263 * Added the cookie checking for initiator in the SKE. It checks
4264 that the responder returns the sent cookie unmodified. The
4265 affected file is lib/silcske/silcske.c. Added new SKE
4266 error type INVALID_COOKIE that can be sent during the
4267 negotiation. Fixed some memory leaks as well.
4269 * Added the "invalid cookie" error message to Irssi SILC client's
4272 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4274 * Added `task_max' field to the SilcClientParams to indicate
4275 the maximum tasks the scheduler can handle. If set to zero,
4276 default values are used. Affected file lib/silcclient/silcapi.h.
4278 * Fixed memory leaks in silc_client_close_connection. Affected
4279 file lib/silcclient/client.c.
4281 * Added silc_client_del_client_entry to client library to free
4282 all memory of given client entry. Affected file is
4283 lib/silcclient/idlist.[ch].
4285 * Added new functions silc_client_del_channel and
4286 silc_client_del_server to delete channel and server entries.
4287 Affected file lib/silcclient/[silcapi.h/idlist.c].
4289 * Removed silc_client_del_client_by_id from silcapi.h.
4291 * Fixed the INFO command to return the server's own info
4292 correctly when querying by Server ID. Affected file is
4295 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4297 * Removed the non-blocking settings in WIN32 code in the
4298 silc_sock_[read/write] and added SleepEx instead. Affected
4299 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4300 of input data is now checked with FIONREAD and ioctlsocket.
4302 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4304 * Call silc_schedule_task_del_by_context in the
4305 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4306 Affected file lib/silccore/silcprotocol.c.
4308 * Call silc_protocol_cancel for active protocols in the
4309 silc_server_close_connection if the funtion
4310 silc_server_free_sock_user_data has not been called.
4311 Affected file silcd/server.c.
4313 * Generic tasks cannot be deleted using the del_by_fd
4314 task deleting function since generic tasks does not match
4315 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4317 * Added a notion to SILCOPER help file that the SILCOPER works
4318 only on router server, not on normal server.
4320 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4322 * Added for WIN32 support for the new scheduler as well.
4323 Affected file lib/silcutil/win32/silcwin32schedule.c.
4325 * Fixed the SHA1 implementation to work on various platforms.
4327 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4329 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4330 API. It is part of the scheduler now. Everything else is
4331 as previously but some functions has changed their names.
4332 Checkout the lib/silcutil/silcschedule.h for the interface.
4333 Updated all applications to use the new interface. Affected
4334 files are lib/silcutil/silcschedule.[ch].
4336 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4338 * Found a bug in the SKE implementation. The HASH value,
4339 specified by the protocol, was not computed correctly. The
4340 public key of the responder was not added to the computation
4341 even though it is mandatory. Affected file lib/silcske/silcske.c.
4342 This unfortunately causes incompatibilities with older
4343 clients and servers.
4345 * Added WIN32 specific network init and uninit functions:
4346 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4347 the Winsock2. Affected file lib/silcutil/silcnet.h and
4348 lib/silcutil/win32/silcwin32net.c.
4350 * Set the socket always to nonblocking mode on WIN32 after
4351 reading data or writing data. Affected file is
4352 lib/silcutil/win32/silcwin32sockconn.c.
4354 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Fixed various compilation problems under WIN32. Affected
4357 files lib/silcutil/win32/silcwin32thread.c and
4358 lib/silcutil/win32/silcwin32schedule.c.
4360 * Removed all _internal.h #includes from public header
4361 files. Internal headers must never be included from
4364 Removed also the lib/silcske/payload_internal.h file.
4366 * All include files that may be needed (public and some others
4367 included by the public headers) by application developers are
4368 now copied to the ./includes directory. It does not copy any
4369 internal headers. Affected file Makefile.defines.pre and all
4370 Makefile.am's under lib/ and subdirs.
4372 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4374 * Do not change the ~/.silc directory's permissions automatically.
4375 Affected file irssi/src/silc/core/clientutil.c.
4377 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4379 * Do not cancel the protocol in silc_server_close_connection
4380 it might cause recursion. Now cancelled in the function
4381 silc_server_free_sock_user_data. Affected file silcd/server.c.
4383 * Fixed the silc_server_remove_clients_by_server to regenerate
4384 the channel keys correctly finally. Added also new function
4385 silc_server_remove_clients_channels to actually do it.
4386 Affected file silcd/server.c.
4388 * Fixed the silc_server_new_channel to not crash by giving
4389 wrong router to the new channel. Affected file is
4390 silcd/packet_receive.c.
4392 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4394 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4395 which is given as argument to the silc_client_alloc now.
4396 It can be used to configure the client and set various parameters
4397 that affect the function of the client.
4399 * The USERS command in server did not check whether the channel
4400 is private or secret. Affected file silcd/command.c.
4402 * Added new argument to the USERS command in protocol specification.
4403 The USERS command now can take the channel name as argument
4404 as well. Added support for this in client and server and
4405 updated the protocol specs.
4407 * Completed the GETKEY command in client. It can be now used
4408 to fetch also servers public key not only some clients.
4409 Affected files lib/silcclient/command[_reply].c.
4411 * Added silc_client_get_server to return server entry by the
4412 server name. Affected files lib/silcclient/silcapi.h and
4415 * Redefined the IDENTIFY command in protocol specification to be
4416 more generic. It now can be used to query information about
4417 any entity in the SILC Network, including clients, servers and
4418 channels. The query may be based either the entity's name
4419 or the ID. Added support for this in both client and server.
4421 Affected files silcd/command.c and lib/silcclient/command.c
4422 and command_reply.c.
4424 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4425 the _from_client and _from_server functions. Affected file
4428 * Added silc_client_get_channel_by_id_resolve to the file
4429 lib/silcclient/silcapi.h to resolve channel information by
4430 its ID. Added also silc_client_get_channel_by_id that
4431 does not resolve it from the server.
4433 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4435 * Added SilcServerEntry context into the client library
4436 to represent one server. The INFO command now allocates
4437 these to save the resolved server info. For now on the
4438 client library will also keep information about servers,
4439 connected and resolved with INFO.
4441 The INFO command now allocates the SilcServerEntry context
4442 and saves the server info there. The COMMAND_REPLY in
4443 the INFO now returns the parameters to application in
4444 same order as defined in the protocol specification.
4446 The entries are cached in the client->server_cache.
4448 * The INFO command is now issued after received the Client ID
4449 from the server. Affected file lib/silcclient/client.c.
4451 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4452 to the application as the mode changer might be server.
4453 It is guaranteed that NULL is not returned anymore to the
4454 application. Affected file lib/silcclient/client_notify.c.
4456 The ID Type is now also passed to the application so that
4457 it can check whether the returned entry is SilcClientEntry
4460 Added new function silc_client_get_server_by_id to return
4461 the server entry by ID. Affected files are the
4462 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4464 * Do not create the channel in the Irssi SILC Client when issuing
4465 the JOIN command but when received the sucessful JOIN command
4466 reply. Otherwise the channel might get created even though we
4467 could not join it. The Affected file is
4468 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4470 * Fixed a channel joining bug in router. The router must also
4471 check the channel modes, invite and ban lists etc. when serving
4472 the JOIN command sent by normal server. Affected file is
4473 silcd/command.c. The router now resolves the client's
4474 information from the server who sent the JOIN command if it
4475 does not know it, and processes the JOIN command only after
4478 * Changed the SilcCommandCb to take new argument; void *context2.
4479 Affected file lib/silccore/silccommand.h
4481 The second argument in the command callbacks in the server now
4482 includes the SilcServerCommandReplyContext if the command was
4483 called as pending command callback from the command reply.
4484 Otherwise it is NULL. When called as pending the status of the
4485 command reply will be checked and if it was erronous the
4486 error will be sent to the original sender of the command.
4487 This way the client always receives the error messages even
4488 though the server was actually the one who received the error
4489 when it resent the command to router, for example. Affected
4490 files silcd/command[_reply].[ch].
4492 * Fixed sending WHOWAS command's error message to client if
4493 the requested client could not be found. It was missing.
4496 * Changed the CMODE and CUMODE commands reply arguments in the
4497 protocol specification. The Channel ID is now sent in both
4498 of the commands to identify the channel. Implemented this
4499 new feature to the client and server. Affected files
4500 lib/silcclient/command_reply.c and silcd/command.c.
4502 * Made better checks for invite and ban lists in the JOIN
4503 command in server. Affected file silcd/command.c.
4505 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4507 * The server now performs the incoming host IP/DNS lookup
4508 using the silc_socket_host_lookup and thus does not block
4509 the server anymore. Affected file silcd/server.c.
4511 * Completed the multi-thread support for SILC Scheduler in
4512 the lib/silcutil/silcschedule.c.
4514 * Fixed the configure.in.pre to detect the pthread correctly
4517 * Fixed a deadlock in silc_task_queue_wakeup in the file
4518 lib/silcutil/silctask.c.
4520 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4522 * Added new function silc_schedule_wakeup that is used in
4523 multi-threaded environment to wakeup the main thread's
4524 schduler. It needs to be used when a thread adds a new task
4525 or removes a task from task queues. After waking up, the
4526 scheduler will detect the task queue changes. If threads
4527 support is not compiled in this function has no effect.
4528 Implemented the wakeup mechanism to both Unix and WIN32
4529 systems. Affected files are lib/silcutil/silcschedule.[ch],
4530 lib/silcutil/unix/silcunixschedule.c and the
4531 lib/silcutil/win32/silcwin32schedule.c.
4533 * Added new function silc_task_queue_wakeup to wakeup the
4534 scheduler by the specified task queue. Affected file
4535 lib/silcutil/silctask.[ch].
4537 * The silc_socket_host_lookup_start now wakes up the scheduler
4538 after adding the timeout task. Affected file is
4539 lib/silcutil/silcsockconn.c.
4541 * The silc_socket_host_lookup is synchronous now if the threads
4542 support is not compiled in. However, the callback is still
4543 called asyncronously through the scheduler, anyway. Affected
4544 file lib/silcutil/silcsockconn.c.
4546 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * Added new function silc_socket_host_lookup to perform
4549 asynchronous IP and FQDN lookups for the socket connection.
4550 Affected files lib/silcutil/silcsockconn.[ch].
4552 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4554 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4555 that may or may not compile the mutex support in.
4557 Changed the silc_mutex_alloc interface. It allocates the
4558 mutex now to the sent pointer and returns TRUE or FALSE.
4560 Affected file lib/silcutil/silcmutex.h.
4562 * Wrote the SILC Task Queue interface to support multi-threads.
4563 Affected file lib/silcutil/silctask.[ch].
4565 * Wrote the SILC Scheduler to support multi-threads. Affected
4566 file lib/silcutil/silcschedule.c.
4568 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4570 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4571 in lib/silcutil/win32/.
4573 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4575 * Defined SILC Mutex API and SILC Thread API and implemented
4576 them for Unix. Affected files are
4577 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4578 lib/silcutil/unix/silcunixmutex.c and
4579 lib/silcutil/unix/silcunixthread.c.
4581 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4583 * Fixed the silc_server_remove_clients_by_server's channel
4584 key re-generation. The hash table handling was incorrect
4585 and would not work with many channels. Affected file is
4588 * Fixed some memory leaks around the server code.
4590 * Rewrote the silc_server_get_users_on_channel to support IPv6
4591 based Client ID's. Affected file silcd/server.c.
4593 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4594 specification. However, a separate document must be written
4595 to define the detailed signing procedure and the payload
4596 associated with the flag. Defined the flag to the
4597 lib/silccore/silcchannel.h as well.
4599 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4601 * Changed the dynamic tables to static size tables in the
4602 lib/silccrypt/silchmac.c.
4604 * Removed GCC dependencies from the code. A patch by cras.
4606 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4608 * Do not show the error "Error receiving packet bla bla"
4609 in server if it really was not an error (-2 means that reading
4610 is pending). Affected file silcd/server.c.
4612 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4614 * Fixed a possible crash in silc_server_remove_clients_by_server
4615 in silcd/server.c. Fixed there also some memory leaks.
4617 * Fixed the silc_idlist_replace_client_id. It could replace
4618 wrong key in the hash table. Affected file silcd/idlist.c.
4620 * Do not check whether there are global users on the channel
4621 if the channel->global_users is FALSE. Affected functions
4622 silc_server_remove_from_one_channel and
4623 silc_server_remove_from_channels in silcd/server.c. Also,
4624 do not check if the removed client is local as we can be
4625 sure that global client was not removed from the channel
4626 and checking for global users is not needed.
4628 * The silc_server_remove_clients_by_server now re-generates
4629 the channel keys correctly for those channels that had
4630 clients removed from them. Affected file silcd/server.c.
4632 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4634 * Found the reason of random crashes in the server. We weren't
4635 ignoring the SIGPIPE signal (which can be sent in write())
4636 and it crashed the server. Affected file silcd/silcd.c.
4638 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4640 * Assure that sock->user_data is not NULL in the function
4641 silc_server_packet_send in silcd/packet_send.c.
4643 * Disconnect the remote connection if it could not be added
4644 to any ID lists in the server. The affected file is
4647 * Check in silc_server_packet_send[_real/dest] that the
4648 socket is not disconnecting and ignore the data if it is.
4649 Affected file silcd/packet_send.c.
4651 * Define inline to __inline on native WIN32 compilation.
4652 Affected file includes/silcwin32.h.
4654 * Added some explicit type casts for inline code since MSVC
4655 require them. Affected files lib/silcutil/silcbuffer.h,
4656 lib/trq/silcdlist.h and lib/trq/silclist.h.
4658 * Print warning in log files from now on if the packet
4659 decryption fails. Affected file silcd/server.c.
4661 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4663 * Changed the `say' client operation's interface to accept
4664 new `type' argument to indicate the type of the message sent
4665 by the library. The application may filter the library's
4666 messages according the type. The affected file is the
4667 lib/silcclient/silcapi.h.
4669 * Added two new functions to lib/silcclient/silcapi.h:
4670 silc_client_del_client and silc_client_del_client_by_id.
4671 Affected file lib/silcclient/idlist.c.
4673 * Moved the clientincludes.h from includes/ to silc/ and
4674 serverincludes.h from includes/ to silcd/.
4676 * The modes for the CMODE and CUMODE are now passed as
4677 uint32 for application with COMMAND_REPLY. The affected
4678 file is lib/silcclient/command_reply.c.
4680 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4682 * /WHOIS without arguments shows client's own information.
4683 Affected file lib/silcclient/command.c.
4685 * Changed PING to not accept any arguments. The specs
4686 says that client can ping only the connected server so
4687 requiring an argument is not needed. Affected file is
4688 lib/silcclient/command.c.
4690 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4692 * Fixed a fatal bug in private message sending and reception
4693 encryption and decryption when using private message keys.
4694 The implementation was incorrect and did not follow the
4695 specification. It causd that some of the message were
4696 lost since it did not use the sending and receiving keys
4697 as the protocol suggests. This has been fixed and will cause
4698 incompatibilities with older clients when sending private
4699 message encrypted with private message keys. Affected files
4700 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4701 and various other in Irssi SILC Client.
4703 Added `responder' boolean argument to the functions
4704 silc_client_add_private_message_key[_ske] to indicate when
4705 the key is added as responder or initiator of the key
4708 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4710 * Removed the silc_ske_check_version function and created
4711 a SilcSKECheckVersion callback. Added also a function
4712 silc_ske_set_callbacks that is now used to set all SKE
4713 callbacks. The callback functions are not given to
4714 the SKE functions anymore, but this function is used to
4717 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4719 * Added `silc_version' argument to the silc_client_alloc
4720 to define the version of the application for the library.
4721 The library will use the version string to compare it
4722 against the remote host's (usually a server) version
4723 string. Affected file lib/silcclient/silcapi.h
4725 * Added the KE protocol context to Key Agreement context
4726 in client library so that we can abort the SKE if it
4727 is in process when we get timeout. Affected file is
4728 lib/silcclient/client_keyagr.c.
4730 * Do not resolve the client ID forever if it returns in the
4731 first time that such client does not exist. This was done
4732 for example with private message. Affected file is
4733 lib/silcclient/client_prvmsg.c.
4735 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4737 * Do not add regex.h for WIN32. The affected file
4738 includes/silcincludes.h.
4740 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4741 not work yet 100%. It generates the DLL's automatically
4742 when compiling with --with-win32 under cygwin.
4744 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4746 * lib/contrib/regex.c is not compiled on WIN32.
4748 * Added silc_net_get_socket_opt function to the
4749 lib/silcutil/silcnet.h.
4751 * Added includes/silcwin32.h for WIN32 specific includes
4754 * Do not use ptime structure or any of the posix process
4755 functions on WIN32 in lib/silccrypt/silrng.c.
4757 * Added silc_gettimeofday to provide generic function
4758 for struct timeval on all platforms. Added the function
4759 to lib/silcutil/silcutil.h.
4761 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4763 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4764 library as they clearly belong there. As a plus side we
4765 can make the actual socket connection routines platform
4768 Added also new generic function silc_socket_read and
4769 silc_socket_write (that used to be silc_packet_[read/write].
4770 The implementation of these are platform specific.
4772 * Added WIN32 specific routines of silc_socket_[read/write]
4773 to lib/silcutil/win32/silcwin32sockconn.c.
4775 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4777 * Added preliminary support for native WIN32 compilation under
4778 cygwin (using the -mno-cygwin option for GCC) to the
4779 ./configure.in.pre. The --with-win32 now prepares the
4780 compilation for native WIN32.
4782 * Rewrote the SILC Scheduler interface in the file
4783 lib/silcutil/silcschedule.h. The scheduler is now context
4784 based and does not have anymore any global static scheduler.
4785 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4786 and created lib/silcutil/win32 directory for WIN32 based
4789 * Added Unix specific network routines to the
4790 lib/silcutil/unix/silcunixnet.c and the old
4791 lib/silcutil/silcnet.c includes now only generic routines.
4793 Added WIN32 specific network routines to the
4794 lib/silcutil/win32/silcwin32net.c.
4796 * Added Unix specific utility functions from the
4797 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4799 * Added WIN32 SILC Scheduler to the file
4800 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4803 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4805 * Do not handle JOIN notify in the server if the target client
4806 is not registered (idata->registered == FALSE). The affected
4807 file is silcd/packet_receive.c.
4809 * Update the nickrec->founder in event_cumode in the Irssi SILC
4810 client. Affected file irssi/src/silc/core/silc-channels.c.
4812 * Fixed the CUMODE_CHANGE notify handling in the server when
4813 server and router are announcing their clients on channels.
4814 Now the mode changes are saved and notified correctly. The
4815 affected file is /silcd/packet_receive.c.
4817 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4818 They really did not replace the cache entry in the ID Cache.
4819 Now they do that. Affected file silcd/idlist.c.
4821 * Fixed the KICK notify handling in the Irssi SILC client to
4822 update the channel records so that the kicked client does not
4823 appear to be on the channel. The affected file is
4824 irssi/src/silc/core/silc-channels.c.
4826 * Always update the conn->current_channel when executing command
4827 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4829 * Fixed the KILL notify handling in Irssi SILC client to remove
4830 the killed client on all channels.
4832 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Fixed the silc_parse_command_line to remove extra spaces
4835 from the start and end of the arguments. Affected file is
4836 lib/silcutil/silcutil.c.
4838 * Cancel and free any active protocol in the function
4839 silc_server_close_connection. Affected file silcd/server.c.
4841 * Cancel and free any active protocol in the function
4842 silc_client_close_connction. Affected file is
4843 lib/silcclient/client.c.
4845 * Do not execute the KILL command for clients that are in
4846 history (ie. they are not in the network). Affected file is
4849 * Fixed KILL notify handling, client does not crash anymore.
4850 Affected file irssi/src/silc/core/silc-channels.c.
4852 * Reduced the default packet buffer size from 2048 to 1024 in
4853 lib/silccore/silcpacket.c.
4855 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4856 counter to the SKE context that is incresed when the SKE library
4857 performs async operation outside the library. If the outside
4858 process frees the SKE context and FREED status will be set
4859 and the library will detect after the sync operation that the
4860 libary is freed. The affected files are
4861 lib/silcske/silcske[_status].[ch].
4863 * Resolve the client entry information in the function
4864 silc_client_channel_message to assure that NULL pointer is not
4865 passed as client entry to the application. */
4867 * Fixed the task timeout calculation to assure that there is
4868 never negative timeouts. The affected file is
4869 lib/silcutil/silcschedule.c.
4871 * Fixed the channel user mode notification sending in server.
4872 It was sent point-to-point to the router (or to server by router)
4873 but it needs to be destined to a channel. The routines now
4874 supports sending the channel user mode notifys to the channels
4875 when announcing clients and channels. Affected files are
4876 silcd/server.c and silcd/packet_receive.c.
4878 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4879 It did not actually replace the old channel entry in the cache.
4880 Affected file lib/silcclient/client_notify.c.
4882 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Fixed a possible crash in silc_packet_send_prepare. It now
4885 assures always that there is enough space in the buffer and
4886 at the tail area of the buffer (for MAC).
4888 Fixed the inbound buffer reallocation in silc_packet_read.
4889 It was old code and did not handle the reallocation correctly.
4892 The affected file is lib/silccore/silcpacket.c.
4894 * Fixed buffer overflow in silc_parse_nickname in the file
4895 lib/silcutil/silcutil.c.
4897 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * make install generates new server keys only if there is not
4902 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4905 Added check that if the NOREPLY is set then we will not send
4906 the away message. This avoids infinite loop of away messages
4907 if both clients are away. The affected file is
4908 lib/silcclient/client_prvmsg.c.
4910 * Fixed client crash if /NICK was given without arguments.
4911 Affected file lib/silcclient/command.c.
4913 * Server does not send the invite list in INVITE command back
4914 to the client if the list was not altered. Added this notion
4915 to the protocol spec as well. Affected file silcd/command.c.
4917 Fixed possible crash in INVITE command by checking the
4918 value of silc_server_get_client_route command.
4920 * Fixed the INVITE notify type handling. The arguments are now
4921 taken in correct order and client does not crash. The affected
4922 file is irssi/src/silc/core/silc-channels.c.
4924 Removed the "Inviting xxx to channel" message from the
4925 client library away and let the application handle it.
4926 Affected file lib/silcclient/command.c. Added that message
4927 to Irssi SILC client's message formats.
4929 * Fixed CMODE command crash in client. It now checks the
4930 amount of arguments correctly and does not crash. The affected
4931 file is lib/silcclient/command.c.
4933 * Do not create new channel automatically in silc_channels_join
4934 but check whether the channel by that name already exists.
4935 Affected file irssi/silc/core/silc-channels.c.
4937 * Do not send the SERVER_SIGNOFF to router if the disconnected
4938 entity was the router. Affected file silcd/server.c.
4940 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4941 SILC client as it was missing from there.
4943 Added the handling of the KICK notify to the Irssi SILC client
4944 as it was missing. Added "you have been kicked" message to
4945 Irssi SILC client's message modules formats.
4947 Added the handing of the KILL notify to the Irssi SILC client
4948 as it was missing. Added the kill message module formats
4951 The affected file is irssi/src/silc/core/silc-channels.c.
4953 * The router did not save the channel mode the server announced.
4954 Affected file silcd/packet_receive.c.
4956 * Fixed a possible crash in INFO command in server. If the
4957 server did not provide the server info it crashed. Affected
4958 file silcd/command.c.
4960 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Fixed the GETKEY command in the server to check also the
4963 global list. Otherwise the GETKEY would not work correctly
4964 in normal SILC server. Affected file silcd/command.c.
4966 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Fixed GETKEY crash, it crashed if the command did not succseed.
4970 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4973 is now real and not just an macro interface to GMP.
4975 Removed the entire GMP from the source tree and imported new
4976 NSS MPI library instead. Reason for removing GMP is that it is
4977 extremely large and compiles extremely slow. The NSS MPI
4978 is only a few files and compiles in less than 10 seconds.
4979 The speed is also about the same as GMP. The MPI is imported
4980 to lib/silcmath/mpi.
4982 If the system has GMP installed we will still use the GMP.
4983 If it is not then the NSS MPI will be compiled.
4985 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Merged a long nickname (127 characters long) crash bugfix from
4988 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4990 * Merged a freed memory reference bugfix from Irssi CVS tree.
4991 Affected file irssi/src/core/commands.c.
4993 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added the server's public key sving and verification to the
4996 server when performing the SKE. This was missing and the
4997 remote server's (or router's) public key was accepted without
4998 checking whether we have it previously or trust it at all.
4999 Affected file silcd/protocol.c.
5001 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Check in the silc_server_timeout_remote if protocol is active
5004 and make sure that the protocol's final callback is called so
5005 that all memory if freed. Affected file silcd/server.c.
5007 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * silc_server_whois_send_reply crashed the server if the nickname
5010 was 127 characters long. Affected file silcd/command.c.
5012 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added sanity check to the silc_server_new_client. If the hostname
5015 is provided inside username then check that the provided hostname
5016 really is the same as the resolved one. If the hostname was not
5017 resolved then check it from the public key. Affected file is
5018 silcd/packet_receive.c.
5020 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5021 if the server disconnected us and the connection is not valid
5022 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5024 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5025 the library to the lib/silcutil/silcutil.[ch].
5027 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Close log file after open. Affected file
5030 lib/silcutil/silclog.c.
5032 * Check whether sock == NULL in silc_client_send_packet and return
5033 if it is. Affected file lib/silcclient/silcclient.c.
5035 * Check rec->entry == NULL in the Irssi SILC Client before
5036 sending the channel message. Affecte file is
5037 irssi/src/silc/core/silc-servers.c.
5039 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Merged a splitted window bugfix from Irssi CVS tree. The
5042 affected file is irssi/src/fe-text/textbuffer-view.c.
5044 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5045 It did not print nickname.
5047 * Improved the distributions system a bit.
5049 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5052 irssi/src/fe-text/gui-window.c.
5054 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5055 to in-active server. The affected file is
5056 irssi/src/silc/core/client_ops.c.
5058 * Resolve the client in USERS command reply if the entry does
5059 not have username resolved. The affected file is
5060 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5061 command to WHOIS command to really resolve stuff. The USERS
5062 is not used any more in any critical section so WHOIS can
5063 be used even though it might be slower than IDENTIFY.
5065 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5068 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Changed the protocol API a bit more consistent in the
5071 lib/silccore/silcprotocol.[ch].
5073 * Changed the following headers to ROBODoc format:
5075 lib/silccore/silcpayload.h
5076 lib/silccore/silcprotocol.h
5077 lib/silccore/silcsockconn.h
5079 All core library headers are now formatted.
5081 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Fixed a bug in Irssi SILC client; do not show that you are
5084 server/router operator if you really are not. Affected file is
5085 irssi/src/silc/core/client_ops.c.
5087 * Renamed silc_command_free_payload to silc_command_payload_free.
5088 Affected file lib/silccore/silccommand.h
5090 * Added silcmath.h to include the prototoypes of various routines
5091 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5094 * Changed the following headers to ROBODoc format:
5096 lib/silccore/silcchannel.h
5097 lib/silccore/silccommand.h
5098 lib/silccore/silcid.h
5099 lib/silccore/silcidcache.h
5100 lib/silccore/silcmode.h
5101 lib/silccore/silcnotify.h
5102 lib/silccore/silcpacket.h
5103 lib/silcmath/silcmath.h
5105 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Added checking to the server code not to start the server if
5108 ciphers and stuff are not configured properly. Affected files
5109 silcd/serverconfig.[h] and silcd/server.c.
5111 * Changed the layout of the header files of the public interfaces
5112 in the SILC libraries. The new layout supports ROBODoc
5113 documentation tool (and some others) so that it is easy to create
5114 a library reference manual. All the other headers and source
5115 code must still follow the CodingStyle document. Also source
5116 code must not include these ROBODoc stuffs, only the headers.
5117 Furthermore, all public interface headers must now be named
5118 by using `silc' prefix, example: silcapi.h, silccipher.h.
5119 Some files were renamed due to this. All the other headers
5120 must not be used as public interfaces. I will update the
5121 CodingStyle document later. Changed following headers, so far:
5123 lib/silcclient/silcapi.h
5124 lib/silccore/silcauth.h
5125 lib/silccore/silcprivate.h
5126 lib/silccrypt/silcdh.h
5128 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Removed silc_client_packet_send_flush from the client library
5133 as it is not needed. Affected file lib/silcclient/client.[ch].
5135 * Added printing of message of unresolved authentication method
5136 to the Irssi SILC client. Added it to the module formats.
5137 Removed the same message from the client library.
5139 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Added new distribution feature, DISTLABEL. Every distribution
5142 can define own preprocessor label that can be used in the
5143 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5144 file distributions, acconfig.h.pre and prepare.
5146 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added Makefile.defines_int to include the actual definitions
5149 for Makefile.defines.in. Tested the new distribution system,
5150 created distributions and tested installation.
5152 * Added AWAY message printing to the Irssi SILC client. Added
5153 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5155 * Added SCONNECT command to call the SILC's CONNECT command.
5156 Cannot use CONNECT directly since Irssi uses that internally.
5157 Affected file irssi/src/silc/core/silc-servers.c.
5159 Added ACTION local command. It is same as ME command but takes
5160 the channel as mandatory argument.
5162 Rewrote some of the Irssi's help files to suite for SILC
5165 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Added Makefile.defines[.in] that should for now on be included
5168 in all Makefile.am file in the source tree. That file includes
5169 all common compilation definitions for SILC source tree.
5171 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Minor changes to the ./prepare script to change the package
5174 name according the distribution name to the configure.in.
5176 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Created new distribution system. Added file `distributions'
5179 that defines all the distributions that can be created out of
5180 the SILC source tree. The ./prepare script now reads that
5181 file to determine how to prepare the distributions. The
5182 first argument to the ./prepare is the name of the distribution
5183 and second is the version of the distribution. If given
5184 without arguments it creates the default (toolkit) distribution
5185 with the default version (defined in ./prepare).
5187 All Makefile.am files that are subject to the distributions
5188 are now named as Makefile.am.pre. These are ./Makefile.am
5189 and lib/Makefile.am. Others may be changed later.
5191 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added invite list, ban list, some key management and connection
5194 error message printing to module formats in the Irssi SILC client.
5196 * Added new silc_client_set_away_message to set the away message
5197 that is back to the person who sent private message. The
5198 affected file lib/silcclient/silcapi.h and the
5199 lib/silcclient/client_prvmsg.c.
5201 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Fixed the private message sending in the Irssi SILC client,
5204 added local command KEY to the Irssi SILC client.
5206 Added key management and key agreement message formats to the
5207 irssi/src/fe-common/silc/module-formats.[ch].
5209 Added USERS (alias WHO) printing, server/router operator
5210 indication and LIST command printing to the module formats.
5212 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Fixed channel joining notify handling, cumode notify handling
5215 from Irssi SILC client.
5217 * Added SILC specific module-formats to the Irssi SILC client so
5218 that SILC specific message hilighting, colors etc is possible.
5219 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5221 Added channel mode, channel user mode, actions, notices,
5222 whois and whowas printing to the the module-formats.c.
5224 * Fixed a bug in channel deletion in the server. The channel
5225 is not left to the cache even if the channel founder auth mode
5226 is set when there are no users anymore on the channel. Affected
5227 file silcd/server.c.
5229 * The silc_net_localhost now resolves the entire hostname including
5230 the domain name. Affected file lib/silcutil/silcnet.c.
5232 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Changed the ask_passphrase client operation to be ascynchronous.
5235 It has now a completion callback and a context that the
5236 application must call after it has got the passphrase from
5237 the user. Affected files lib/silcclient/silcapi.h,
5238 lib/silcclient/protocol.c, lib/silcclient/command.c and
5241 Added SilcAskPassphrase callback that the application calls
5242 to deliver the passphrase to the library.
5244 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5245 The public key verification and especially a certificate
5246 verification is asynchronous procedure.
5248 Added new SILC_SKE_STATUS_PENDING status to indicate the
5249 request is pending and a callback will be called to finalize
5252 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5253 indicate that remote end did not send its public key (or
5254 certificate), even though we require it. Added check for this
5255 condition in the SKE. This was a security bug, now fixed.
5257 Defined new SilcSKEVerifyCbCompletion callback that is called
5258 when the verification process is completed.
5260 The affected files lib/silcske/silcske_status.h and
5261 lib/silcske/silcske.[ch].
5263 * Changed the verify_public_key client operation to be async
5264 as well. Defined SilcVerifyPublicKey callback that is used to
5265 indicate the success of the public key verification process.
5267 Changed the server and client to use the new async client
5270 * Changed the Irssi SILC client's internal scheduler to be called
5271 twice as many times as it used to be. As a result the client
5272 should be a bit faster now. Affected file is
5273 irssi/src/silc/core/silc-core.c.
5275 * Added support to Irssi SILC client of asynchronous public key
5276 verification and passphrase inquiry. Affected file is
5277 irssi/src/silc/core/silc-core.c.
5279 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Do not say "You have left channel %s" in client library.
5282 Moved it to the application. Affected files are
5283 lib/silcclient/command.c and silc/client_ops.c.
5285 * Fixed silc_client_get_clients. Command context was not
5286 duplicated and was freed memory in the callback. Affected
5287 file lib/silcclient/idlist.c.
5289 * Do not say "you are now talking..." on JOIN command in the
5290 client library. The appliation must handle it.
5292 * Do not say ".. changed topic to" in command reply in the
5293 client libary. The application must handle it.
5295 * Fixed TOPIC command sending in the client library.
5297 * Fixed a memory leak in silc_client_command_free in the file
5298 lib/silcclient/command.c.
5300 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Imported a modified version of Irssi client to the source tree.
5303 The Irssi will be used to create a new client called
5304 Irssi SILC. Imported to irssi/.
5306 Added silc_core_init_finish function to the Irssi. Affected
5307 file irssi/configure.in.
5309 A lot changes in the Makefile.ams around the irssi tree.
5311 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Do not rehash if the new size is same as the old size of the
5314 hash table, in the silc_hash_table_rehash*. The affected file
5315 lib/silcutil/silchashtable.c.
5317 * Replaced hash_table_del_by_context calls from the server
5318 (when channel->user_list and client->channels) to the
5319 hash_table_del as it is sufficient and faster.
5321 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added silc_hash_table_list, silc_hash_table_get and the
5324 SilcHashTableList structure to provide an alternative way to
5325 traverse the hash table. The affected files are
5326 lib/silcutil/silchashtable.[ch].
5328 * Changed the server's idlist routines to use the hash table
5329 routines to optimize the code.
5331 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Replaced the client entry's `channel' list and channel entry's
5334 `user_list' list to hash tables for optimized lookup. Changed
5335 the code to use the hash table interface around the code.
5336 Affected file lib/silcd/idlist.[ch].
5338 * Added `auto_rehash' boolean argument to the function
5339 silc_hash_table_alloc to indicate whether the hash table should
5340 auto-rehash when it thinks is appropriate time. It will
5341 increase the hash table size if the there is twice as much
5342 entries in the table than the size of the table, and will
5343 decrease the size if there are twice as less entries than
5344 the size of the table.
5346 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5350 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * silc_idcache_purge_by_context deletes the entry now by context
5353 as it is supposed to do. Affected file lib/silccore/idcache.c.
5355 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5356 client is not anymore valid (WHOWAS givens the info) and not
5357 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5359 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Removed the `data' and `data_len' arguments from the ID Cache
5362 interfaces and added `name' argument. ID Cache does not handle
5363 anymore the binary data only a names associated with given ID.
5365 * When hashing a Client ID with silc_hash_id the entire ID is
5366 not hashed anymore, instead only the hash of the Client ID is
5367 hashed. This way we can access the Client ID from the cache
5368 with Client ID but with the hash of the ID (which is a hash of
5369 the nickname) as well without any difference in performance.
5371 Added also silc_idcache_find_by_id_one_ext to do one on one
5372 searching when we have the actual ID. Added also function
5373 silc_hash_client_id_compare. The affected files are
5374 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5376 * When hashing the name associated with a ID it is always done
5377 in lowercase. This way we can access the cache without worrying
5378 about case-sensitivity, even though, for example nicknames are
5381 * Fixed a bug in server with channel message sending. It put
5382 wrong ID type as destination ID. The affected file
5383 silcd/packet_send.c.
5385 * silc_idcache_del_by_context now deletes from all hash tables
5386 by context. Affected file lib/silccore/idcache.c.
5388 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Changed the client library to use the new ID Cache interface.
5391 Changes around the source tree.
5393 * Added silc_hash_table_rehash_ext to rehash with specific
5394 hash function. Affected file lib/silcutil/silchashtable.[ch].
5396 * Added silc_hash_string_compare to compare two strings in the
5397 hash table. Affected file lib/silcutil/silcutil.[ch].
5399 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added new function silc_idcache_del_by_context into the
5402 lib/silccore/idcache.[ch].
5404 * Changed the server's ID list routines to use the new ID Cache
5405 interface. Changes around the source tree.
5407 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added silc_hash_table_del[_by_context]_ext functions in to the
5410 lib/silcutil/silchashtable.[ch].
5412 Removed silc_hash_table_find_all* routines and added new
5413 silc_hash_table_find_foreach to replace them.
5415 Added silc_hash_table_replace_ext function as extended
5416 replacing function. Separated the simple hash table interface
5417 from the extended hash table interface in the file
5418 lib/silcutil/silchashtable.h.
5420 * Fixed minor bugs and changed it to use some of the new
5421 hash table functions in lib/silccore/idcache.c
5423 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Added new function silc_hash_table_find_all to return all keys
5426 in the hash table by the specified key. As the hash table is
5427 collision resistant it also makes it possible to have several
5428 duplicate keys in the hash table. This function may be used to
5429 find all of the keys from the hash.
5431 Added user_context arguments to the SilcHashFunction,
5432 SilcHashCompare and SilcHashDestructor to deliver user specified
5435 Added new fuctions silc_hash_table_find[_all]_ext to do
5436 extended lookup with specified hash and compare functions and
5437 specified user contexts.
5439 Added new function silc_hash_table_add_ext to add the key
5440 with specified hash function and user context.
5442 Added new function silc_hash_table_foreach to traverse all
5443 entrys in the hash table. Added SilcHashForeach callback
5446 Added new function silc_hash_table_del_by_context to delete
5447 the entry only if the context associated with the key matches.
5449 Affected files are lib/silcutil/silchashtable.[ch].
5451 * Removed silc_hash_[server/client/channel]_id and added just
5452 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5453 silc_hash_id_compare to compare two ID's using as the hash table
5454 comparison function. Added also silc_hash_data to hash
5455 binary data and silc_hash_data_compare to compare it.
5457 * Removed silc_idlist_find_client_by_hash as it is not needed
5458 anymore. Affected file silcd/idlist.[ch].
5460 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5461 to use internally the SilcHashTable. The new ID Cache is a lot
5462 faster than the old one. Some of the ID Cache interface was also
5463 rewritten and obsolete and stupid functions were removed.
5465 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Added entry_count field to the SilcHashTable to keep the number
5468 of the entries in the table. Implemented the function
5469 silc_hash_table_rehash. Added new function
5470 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5472 Fixed a minor bug in silc_hash_table_free.
5474 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5475 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5476 into the lib/silcutil/silcutil.[ch].
5478 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Implemented a collision resistant hash table into the
5481 lib/silcutil/silchashtable[ch]. See the header and the source
5482 for the SilcHashTable API.
5484 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Merged dotconf version 1.0.2 into lib/dotconf.
5488 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Do not compile anything in lib/silcsim/* if the SIM support
5491 is not enabled. The tree should now compile without problems
5494 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Compiled the SILC under cygwin. Compiled and tested briefly
5497 without problems. More tests needed. The SIMs didn't compile
5500 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5502 * Fixed possible crash in silc_get_username in the
5503 lib/silcutil/silcutil.c.
5505 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Fixed a va_arg in silc/client_ops.c.
5509 * Oops, RC5 routines were named AES and caused some problems
5510 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5512 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Added new SilcIDIP structure into the lib/silccore/id.h and
5515 replaced the old `ip' fields from all SILC ID's to that type.
5516 This is a step towards IPv6 support.
5518 The silc_id_get_len takes now the ID as an extra argument.
5519 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5520 both IPv4 and IPv6 based ID's.
5522 The affected files are lib/silccore/id.[ch] and other files
5523 around the tree using these routines.
5525 * Removed the ID length arguments in server from various
5526 silc_server_send_notify_* routines -> they are not needed
5529 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Fixed memory leak in silc_encode_pem_file in the file
5532 lib/silcutil/silcutil.c.
5534 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Check minor version as well in the SKE. Affected files are
5537 silcd/protocol.c and lib/silcclient/protocol.c.
5539 * Added --identifier option to the server so that an identifier
5540 can be when creating the public key for the server. Affected
5541 file is silcd/silcd.c.
5543 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5544 lib/silccrypt/silcpkcs.c.
5546 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Register default ciphers and stuff when using -C option with
5549 the server. Affected file sildc/silcd.c.
5551 * Put back the servers public key filename format, it is better
5552 than the new one. For now, the client keys are saved with the
5553 new filename format. The affected file silc/client_ops.c.
5555 * Implemented the Cipher API for the rest of the ciphers that
5556 did not implement it or implemented it the wrong way.
5558 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Register default ciphers and stuff when using the -S option
5561 in the client. Affected file silc/silc.c. Same also when
5562 creating new key pair with -C option.
5564 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Fixed the silc_verify_public_key client operation function to
5567 save the public keys differently. The fingerprint is now
5568 used as filename and not the hostname. This way also the
5569 client keys are saved uniquely and not with hostnames. The
5570 affected file is silc/client_ops.c.
5572 * Trimmed the silc_hash_fingerprint function to remove extra
5573 whitespaces from the end of the fingerprint. The affected
5574 file is lib/silccrypt/silchash.c.
5578 * Added silc_cipher_register_default function to register all
5579 default ciphers. It can be used when configuration files
5580 does not exist and the application does not want any specific
5581 ciphers in any specific order.
5583 The SilcDList is now used as silc_cipher_list dynamically
5584 allocated cipher list. Removed the static list all together
5585 and now all ciphers must be allocated to the dynamic list.
5586 The silc_cipher_alloc routine was changed to check only the
5589 All silc_cipher_* routines that used to return int returns
5592 The affected files lib/silccrypt/silccrypt.[ch].
5594 * The same thing was done to silc_hash_* as for silc_cipher_*
5595 routines. Affected files lib/silccrypt/silchash.[ch].
5597 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5598 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5599 Added also silc_pkcs_[un]register[_default] functions.
5600 Removed the data_context from the PKCS API.
5602 * Added silc_hmac_register_default function to register default
5603 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5604 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5605 to unregister all hmacs at once.
5607 * Register the default ciphers, hash functions, PKCSs and HMACs
5608 if client's configuration file does not exist. The affected
5611 * The client did not load the hash functions from the SIM
5612 modules at all. Added support for this. Affected file is
5613 silc/clientconfig.c.
5615 * When decoding public key with silc_pkcs_public_key_decode, check
5616 the supported algorithm only if PKCS are registered. Affected
5617 file lib/silccrypt/silcpkcs.c. The same was done with the
5618 silc_pkcs_private_key_decode.
5620 * Fixed the SILC List routines to keep the list always in order.
5621 It used to change the list's order when traversing the list but
5622 not it preserves the order. Affected file lib/trq/silclist.h.
5624 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added the client library to use the SilcSocketConnection's
5627 reference counter (by silc_socket_dup) to prevent the bug that
5628 the socket object may be freed underneath async operation.
5630 * The name resolv library checking fixes in the configure.in.pre.
5633 * Created new version of the protocol drafts for future
5634 development. The -03 drafts are the ones that will be changed
5635 in the trunk now and the -02 will remain as they are.
5637 * Send list of CUMODE notifys to the router when announcing
5638 the channel users to the router. Affected file silcd/server.c.
5639 If the router receiving channel founder CUMODE for a channel
5640 that already has channel founder it will send CUMODE notify
5641 to the sender to remove the channel founder rights from the
5642 announced client. Affected file silcd/packet_receive.c.
5644 * The CUMODE notify may now use Server ID as well as the entity
5645 who changes the mode. Updated protocool specs.
5647 * Updated INSTALL and README files.
5649 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * New web pages in the http://silc.pspt.fi. The pages was
5656 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Implemented the [DenyConnectin] config section in the server.
5659 Added silc_server_config_denied_conn to check whether incoming
5660 connection is denied. Affected file silcd/serverconfig.[ch].
5662 * Do not check the ports when checking the incoming configuration
5663 data if the port is 0, meaning any. Affected file is
5664 silcd/serverconfig.c.
5666 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Fixed buffer overflow in silc_string_compare in the file
5669 lib/silcutil/silcutil.c.
5671 * Fixed double free in silc_server_command_leave in the file
5674 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Fixed the version checking in the server. Affected file is
5679 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Fixed the configuration data fetching when accepting new
5682 connections in the server. Affected file silcd/server.c.
5684 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Added `sender_entry' argument to the function
5687 silc_server_packet_relay_to_channel so that we can check
5688 whether some destination actually belongs to the same route
5689 the sender belongs (ie, we must not resend the packet to the
5690 sender). Affected file silcd/packet_send.[ch].
5692 * Added `servername' field to the SilcClientEntry in the server
5693 to hold the name of the server where client is from. Affected
5694 file is silcd/idlist.h.
5696 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Moved the channel message encrypting in the router betwen
5699 router connections from silc_server_channel_message to the
5700 silc_server_packet_relay_to_channel since we want to check
5701 whether we have anybody channel before encrypting anything.
5702 Affected files silcd/packet_[receive/send].c.
5704 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Fixed the [AdminConnection] server config section to support
5707 multiple entries. Affected file silcd/serverconfig.c.
5709 * Added support into the server to check the validity of the
5710 incoming connection before executing any KE or authentication
5713 * The connection configuration is now saved to the KE and
5714 connection auth protocol contexts and not fetched anymore in
5715 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5717 * The local hosts listenning address and port is also resolved
5718 now when starting the server. We want to have the socket object
5719 to include the real address and port for the listener. Added
5720 new function silc_net_check_local_by_sock into the files
5721 lib/silcutil/silcnet.[ch].
5723 * Fixed a broadcast bug in server -> do not broadcast if we
5726 * Fixed a routing bug. Do not route broadcast packets ever.
5727 Broadcast packets must be processed always and not routed since
5728 they may be destined to some other host than yourself and thus
5729 would get routed without no good reason. Affected file is
5732 * Added function silc_server_config_is_primary_route to check
5733 whether primary router connection has been configured (a router
5734 configuration that we are initiating). If there is not, we
5735 will assume that there is only two routers in the SILC network
5736 and we will use the incoming router connection as our primary
5737 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5739 * Changed the order of the broadcasting. Broadcast _after_ the
5740 packet has been processed not before. Affected file is
5743 * Fixed a [ClientConnection] parsing bug. The port was never
5744 parsed correctly thus resulting to port 0. Affected file
5745 silcd/serverconfig.c.
5747 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5748 argument and did not set the broadcast packet flag. Affected
5749 file silcd/packet_send.c. Fixed same bug in the function
5750 silc_server_send_notify as well.
5752 * If we receive NEW_ID packet for our own ID in the server, ignore
5755 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Removed the nickname from the Private Message Payload.
5760 Updated the code and the protocol specs.
5762 * Updated protocol specs for submitting to the IETF.
5764 * Tweaked the Random Number Generator a bit. Affected file
5765 lib/silccrypt/silcrng.c. Exported a new function
5766 silc_rng_[global]_add_noise which can be used to add more
5769 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Do not parse packets with different timeout when protocol
5772 is active -> may cause problem with rekey. Affected file
5775 * When server receives signoff notify it must not create
5776 new channel key if the client is on any channels since the
5777 sender of the signoff notify will create it.
5779 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Added printing of error messages during SKE protocol from the
5782 failure packet sent by server during SKE. Affected file
5785 * Removed the client's failure_callback handling with timeout
5786 and handle it immediately when received.
5788 * The SKE library returned wrong type in SUCCESS and FAILURE
5789 packets. They must be 32 bit MSB not 16 bit MSB.
5791 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Ok, rewrote the logic of the re-key and now it seems to work.
5794 I tested it on high traffic with frequent re-keys without
5795 problems. Added hmac_receive (and renamed hmac to hmac_send)
5796 in SilcClientConnection in lib/silcclient/client.h and
5797 in SilcIDListData in silcd/idlist.h. Also, removed the
5798 SilcPacketParserContext's cipher and hmac fields as they are
5799 not needed anymore and actually caused some problems when
5800 the ciphers and hmac's changed underneath the packet parser.
5802 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * If re-key protocol is active then process the incoming packets
5805 synchronously since we must assure that icoming packets encrypted
5806 with the old key is processed before the new keys is set to
5807 use. This is true other packets than for REKEY packets.
5808 Affected file silcd/server.c. The same was done to client library
5809 as well, affected file lib/silcclient/client.c.
5811 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Fixed bug in client and server to accept the force send if
5814 the packet is send from silc_[server/client]_packet_process
5815 function. Otherwise the packets are never delivered, oops.
5817 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Disable force sending of packets when REKEY protocol is active.
5820 We must assure that no packet is sent directly when rekey is
5821 performed. All packets must be sent through packet queue.
5822 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5823 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5824 function is silc_[server/client]_packet_send_real to check
5827 * Replaced the SIM paths from example config files to
5828 /usr/local/modules. Also, make install creates now
5829 /usr/local/silc/logs directory to hold all the SILC server
5832 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Made the configure.in.pre work on Solaris. Patch by salo.
5836 * Made all ciphers compatible with non-x86 machines. Defined
5837 CBC mode macros into lib/silccrypt/ciphers_def.h.
5839 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Fixed the make install.
5843 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * When MAC computation fails the silc_packet_decrypt returned 0
5846 even though it was supposed to return -1. Fixed this. The
5847 affected file is lib/silccore/silcpacket.c.
5849 * Do not replace the config files in /etc/silc (in make install)
5850 if they already exist. Affected file ./Makefile.am.
5852 * Do not send re-key packets immediately but through packet queue.
5853 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5855 * Changed silc_net_check_host_by_sock to return FALSE if the
5856 IP/DNS could not be resolved. Though, it returns the IP address
5857 now even if it could not resolve it (but returns also FALSE).
5858 Affected file lib/silcutil/silcnet.[ch].
5860 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Added silc_pkcs_decode_identifier to decode the public key's
5863 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5864 Added also silc_pkcs_free_identifier. Added also new context
5865 SilcPublicKeyIdentifier.
5867 * Added -S option to the silc client. It is used to dump the
5868 contents of the specified public key file.
5870 * Changed the PKCS api to return the public key length when
5871 setting the public key.
5873 * Fixed a fatal bug in the public and private key file loading.
5874 Affected file lib/silccrypt/silcpkcs.c.
5876 * Execute the packet parsing for client with zero (0) timeout
5877 if the protocol is active. Affected file silcd/server.c.
5879 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Made the key generation options to the silcd program. Added
5882 -C option, equivalent to client's option.
5884 * Added new [ServerKeys] config section to the server. It
5885 configures the server's public and private key.
5887 * Defined generic Public Key Payload into the protocol
5888 specification to send specific type of public keys and
5891 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5892 public key or certificate.
5894 * Implemented the GETKEY command to the server and to the
5895 client library and on user interface.
5897 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Made preliminary `make install' work.
5901 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Added SilcServerRekey context into silcd/idlist.h.
5905 * Added the PFS support as defined in the specification to the
5906 SKE protocol. Affected files lib/silcske/*.c.
5908 * Added `ske_group' field to the SilcServerRekey context to hold
5909 the number of the SKE group that is used with PFS in re-key.
5910 Affected file silcd/idlist.h.
5912 * Added PFS re-key support to the server. Affected file is
5915 * Added silc_protocol_cancel to cancel execution of the next
5916 state of the protocol. Affected file is
5917 lib/silccore/silcprotocol.[ch].
5919 * Added the re-key support with and without PFS to the client
5920 library. Re-key is performed once in an hour, by default.
5922 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5923 Added silc_client_rekey_callback and silc_client_rekey_final.
5924 Affected files are lib/silcclient/protocol.[ch] and
5925 lib/silcclient/client.[ch].
5927 * Removed the `hmac_key' and `hmac_key_len' fields from the
5928 SilcClientConnection structure; not needed. Affected file is
5929 lib/silcclient/client.h.
5933 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Do not ask whether user wants to use the negotiated private key
5936 for private messages, just use it. Affected file is
5937 silc/local_command.c.
5939 * Added `send_enc_key' and `enc_key_len' fields to the
5940 SilcIDListData structure since they are needed in the re-key
5941 phase. Affected file is silcd/idlist.[ch].
5943 * Implemented the simple re-key protocol into the server.
5944 Affected files silcd/server.c and silcd/protocol.[ch]. The
5945 re-key will be performed once in an hour, by default.
5947 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5948 Added silc_server_rekey, silc_server_rekey_callback and
5949 silc_server_rekey_final.
5951 * Removed Tunneled flag from the protocol. Updated the code
5952 and the specifications.
5954 * Adde `pfs' field to the SilcIDListData to indicate whether
5955 the PFS is to be performed in the re-key. Affected file is
5958 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5961 int64 of at least the xintXX size. If void * is less that 4
5962 bytes uint32 * will be used. Defined bool as boolean.
5964 * Changed _ALL_ unsigned long and unsigned int to uint32,
5965 unsgined short to uint16 in the source tree.
5967 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5968 not handle clients that has entry->data.registered == FALSE.
5969 They are not in the network anymore. Affected file is
5972 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Implemented the sending of the SERVER_SIGNOFF notify in the
5975 server. Affected file is silcd/server.c.
5977 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5978 Added also silc_notify_payload_encode_args into the
5979 lib/silccore/silcnotify.[ch].
5981 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5982 Affected file silcd/packet_receive.c.
5984 * Implemented the SERVER_SIGNOFF notify handling in the client
5985 library. Affected file lib/silcclient/client_notify.c. Also,
5986 implemnted the printing of the SERVER_SIGNOFF info to the
5987 application. Affected file silc/client_ops.c.
5989 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5990 if the deleting was successful. Affected file silcd/idlist.[ch].
5992 * Added support for public key authentication in the connection
5993 authentication protocol in the client library. Affected file
5994 lib/silcclient/protocol.c.
5996 * Changed the server's silc_idlist_get_clients_by_* interface
5997 to support already allocated array so that new entries may be
5998 added to pre-allocated array. Affected file silcd/idlist.[ch].
5999 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6000 and command replies.
6002 * All command reply functions in the server now calls the
6003 pending command callback even if error occured. This way the
6004 error will be delivered to the client as well. Affected files
6005 silcd/command.c and silcd/command_reply.c.
6007 * Fixed INFO command to return local server's info if no server
6008 was provided. Affected file lib/silcclient/command.c.
6010 * Removed RESTART command for good. Updated the code and the
6013 * Rewrote parts of the task system. It is a bit simpler now.
6014 Removed unsued task priorities. The affected files are
6015 lib/silcutil/silctask.[ch].
6017 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Moved the USERS printing from the library to the application.
6020 Affected files lib/silcclient/command.c and silc/client_ops.c.
6022 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Added channel key re-key support. The re-key is perfomed
6027 only by the router and is done once in an hour. Added `rekey'
6028 field to the SilcChannelEntry in the server. Affected files
6029 silcd/server.c and silcd/idlist.h.
6031 * Added silc_task_unregister_by_context into the file
6032 lib/silcutil/silctask.[ch].
6034 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Added SILC_UMODE_GONE mode to indicate when the client is not
6037 present in the SILC network. Added also support to the local
6038 command AWAY that will set this mode. Added support of showing
6039 "xxx is gone" in WHOIS command. The USERS command shows the
6040 gone status as well.
6042 * Fixed setting server and router operator privileges in the
6043 server's UMODE command. Affected file silcd/command.c.
6045 * Merged the SKE KE1 and KE2 payloads into one payload. The
6046 new KE payload is equivalent to the old KE2 payload.
6048 Cleaned up the SKE Start Payload parsing. It now uses the
6049 simple buffer unformatting to do the parsing. A lot faster
6052 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6053 to the SKE that is used to indicate whether both of the SKE
6054 parties should perform authentication. By default only the
6055 responder performs authentication. By setting this flag also
6056 the initiator must do authentication. By default it is unset
6057 since in normal SKE case, client to server connection, only
6058 the responder should do authentication. When doing SKE between
6059 two clients both should perform authentication. Updated the
6060 code and the protocol specs.
6062 * A little fix to IDENTIFY command in the server. Search the
6063 client first by hash not nickname. Affected file is
6066 * Fixed the silc_client_close_connection to support closing
6067 the client to client connections wihtout deleting too much
6068 data. Affected file lib/silcclient/client.c.
6070 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6071 are received if protocol used to be active but is not anymore
6072 the application would crash due to NULL pointer dereference.
6073 Affected files silcd/server.c and lib/silcclient/client.c.
6075 * Added `hash' field to the SilcClientConnection to include
6076 the hash function negotiated in the SKE protocol.
6078 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6079 to set the channel founder authentication data. A client can
6080 claim the founder rights later by providing the authentication
6081 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6082 This way the channel founder can regain the channel founder
6083 privileges even it is left the channel. This works only on
6084 local server and the client must be connected to the same
6085 server to be able to regain the founder rights. Updated the
6086 protocol specs accordingly.
6088 Added support to the CMODE command in the client to set the
6089 founder auth data. Read the README to see how to set it.
6091 Added support to the CUMODE command to claim the founder
6092 rights. Read the README to see how to do it.
6094 Added support for the founder authentication to the Channel
6095 Entry in the server. Affected file silcd/idlist.h.
6097 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6098 server's CMODE command. Affected file silcd/command.c.
6100 * Added the following new functions into lib/silccore/silcauth.[ch]:
6101 silc_auth_get_method and silc_auth_get_data.
6103 * The server now saves the remote hosts public key to the
6104 SilcIDListData pointer. Affected file silcd/protocol.c.
6106 * The normal server now does not remove the channel entry from
6107 the cache if the founder authentication data is set. It used
6108 to remove it if the founder was the last one on the channel on
6109 the server and left the channel. The auth data is saved and
6110 if the channel is re-joined later the old entry is used with
6111 the old auth data. Affected files silcd/command_reply.c and
6114 * Removed the `pkcs' field from the SilcIDListData structure
6115 in the server; it is not used. Affected file silcd/idlist.h.
6117 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Fixed packet processing on slow links. Partial packets were
6120 never re-processed because the incoming data buffer was cleared
6121 by the application. Application must not directly clear the
6122 sock->inbuf, the packet processing routines handle it. Fixed
6123 this in client library and in server.
6125 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Fixed the WHOIS and IDENTIFY send reply function to really
6128 check whether to send list or just one entry. Affected file
6131 * Cleaned up the LEAVE command's channel key distribution. The
6132 affected file silcd/command.c.
6134 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6135 can enforce the channel mode as well. In that case the ID
6136 includes the ID of the server. The code now enforces the
6137 mode change if the router have different mode than the server.
6139 * The notify client operation with CMODE_CHANGE notify can now
6140 return NULL client_entry pointer if the CMODE was not changed
6141 by client. Application must check for this.
6143 * Added <Server ID> argument to INFO command to support server
6144 info fetching by Server ID.
6146 * Added silc_server_announce_get_channel_users to get assembled
6147 packets of channel users of the specified channel. Affected
6148 file silcd/server.[ch].
6150 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6151 was freed underneath the ID Cache.
6153 * Re-announce clients when the server received CHANNEL_CHANGE
6154 notify from the router. Affected file silcd/packet_send.c.
6156 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6159 crashed since it did not handle the fact that there is no cipher
6160 called "3" and didn't check the error condition. Now fixed.
6162 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6163 flag. It can be used to send message requests.
6165 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Implemented the RESTART command in the client.
6169 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6170 notice type messages. Added notice printing to the user
6173 * The channel keys are not re-generated if the channel's mode
6174 is PRIVKEY, ie private key on the channel exists. Affected
6175 files silcd/server.c and silcd/command.c.
6177 * Fixed a little bug in channel message delivery when channel
6178 private keys are set in the server. Affected file is
6179 silcd/packet_send.c.
6181 * Changed the setting on channel->on_channel = TRUE from the
6182 silc_client_save_channel_key to the JOIN command reply. The
6183 key payload is not received if the private channel key is set.
6184 Affected file lib/silcclient/command_reply.c and the
6185 lib/silcclient/client_channel.c.
6187 * When the CMODE_CHANGE notify is sent and the channel private
6188 key mode is removed the channel key must be re-generated in
6189 other cells as well. Added this support for the router in the
6190 silcd/packet_receive.c.
6192 * Added new local command NOTICE to send notice message on
6193 channel. Affected file silc/local_command.[ch].
6195 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Added new local command ME to the client. It is used to send
6198 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6199 some action. Affected file silc/local_command.[ch].
6201 * Changed channel_message and private_message client operations
6202 to deliver the message flags to the application. Added also
6203 the `flags' arguments to the silc_client_send_channel_message
6204 and silc_client_send_private_message functions. Affected file
6207 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Redefined the Private Message Payload to support private message
6210 keys and to support the new private message flags. Updated
6211 the protocol specs. Flags makes it possible to have for example
6212 CTCP style messages.
6214 * Added new type SilcPrivateMessagePayload and defined an API
6215 for it in the lib/silcclient/silcprivate.[ch].
6217 * Tested private message private keys successfully. Tested the
6218 private message key set, unset and list commands with the new
6221 * Redefined the Channel Message Payload to include the channel
6222 message flags (equal with private message flags) to support
6223 for example CTCP style messages.
6225 * Defined some of the message (for channel and private message)
6226 flags. Updated the protocol specs and added the flags to the
6227 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6229 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Added SilcKeyAgreementStatus type to the key agreement routines
6232 to indicate the current status and error if one occured.
6233 The status types are defined in the lib/silcclient/silcapi.h.
6235 * Added new local command KEY that is used to set and unset private
6236 keys for channels, set and unset private keys for private messages
6237 with remote clients and to send key agreement requests and
6238 negotiate the key agreement protocol with remote client. The
6239 key agreement is supported only to negotiate private message keys,
6240 it currently cannot be used to negotiate private keys for channels,
6241 as it is not convenient for that purpose.
6243 * Fixed a minor pending callback setting bug in the function
6244 silc_client_get_client_by_id_resolve, now the function works.
6245 Affected file lib/silcclient/idlist.c.
6247 * Added function silc_net_get_local_port to get local bound
6248 port by socket. Added to lib/silcutil/silcnet.[ch].
6250 * Added `sockets' and `sockets_count' fields to the SilcClient
6251 object. They hold the sockets of the listenning sockets in
6252 the client. Listenning sockets may be for example the key
6253 agreement server. Affected file lib/silcclient/client.[ch].
6254 Added functions the silc_client_add_socket and the
6255 silc_client_del_socket. They are exported to the application
6258 * Added ~./silc/clientkeys to support other client's public keys.
6260 * Renamed verify_server_key client operation to verify_public_key
6261 and added one argument to indicate the type of the connection
6262 (server, client etc.).
6264 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Added silc_server_connection_auth_request to handle the
6267 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6268 silcd/packet_receive.[ch].
6270 * Added silc_server_send_connection_auth_request into the
6271 silcd/packet_send.c to send the connection auth request packet.
6273 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6276 * Fixed the public key authentication in responder side in the
6277 server. The `auth_data' pointer includes the SilcPublicKey
6278 not the path to the public key. Affected file silcd/protocol.c.
6280 * Implemented the public key authentication in the initiator side
6281 in the server. Affected file silcd/protocol.c.
6283 * Removed the [RedirectClient] config section from the server
6284 configuration. Is not needed and I don't want to implement it.
6286 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Cleaned up the CMODE command in the server. It now works
6289 correctly and supports all the modes defined in the protocol.
6290 Affected file is silcd/command.c.
6292 * Added `hmac_name' field to the SilcChannelEntry in the server
6293 to hold the default HMAC of the channel. It can be set when
6294 creating the channel (with JOIN command). Affected files
6297 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6298 type to indicate the change of the current cipher and hmac
6299 on the channel. Client can safely ignore the <cipher> argument
6300 (if it chooses to do so) since the CHANNEL_KEY packet will
6301 force the channel key change anyway. The <hmac> argument is
6302 important since the client is responsible of setting the new
6303 HMAC and the hmac key into use.
6305 * Fixed the CMODE command in the client library as well.
6307 * Tested CMODE command in router environment successfully.
6309 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Show the version of the remote client (or server) when connecting
6312 to the server. It is logged to the log file. Affected file
6313 is silcd/protocol.c.
6315 * Fixed the KILLED notify handling in the client library. The
6316 client must be removed from all channels when receiving the
6319 Also, do not remove the client entry when giving the KILL
6320 command but when the KILLED notify is received.
6322 * Removed silc_idlist_find_client_by_nickname from the server.
6323 Not needed anymore. Affected files silcd/idlist.[ch].
6325 * Implemented the CHANNEL_CHANGE notify type handling to the
6326 server. Affected file silcd/server.c.
6330 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6344 * Added function silc_server_get_client_resolve to find the
6345 client entry by ID from all ID lists and then resolve it
6346 (using WHOIS) if it cannot be found. Affected file is
6349 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Implemented the BAN command to the client library.
6353 * The JOIN command in the server now checks the invite list
6356 * Changed the silc_command_reply_payload_encode_va and the
6357 silc_command_payload_encode_va to support that if argument is
6358 NULL it ignores and checks the next argument. Affected file
6359 lib/silccore/silccommand.c.
6361 * Added silc_server_send_notify_ban to send the BAN notify
6362 type between routers.
6364 * Chaned the silc_notify_payload_encode to support that if
6365 argument is NULL it ignores and checks the next argument.
6366 Affected file lib/silccore/silcnotify.c.
6368 * Tested ban lists in router environment successfully.
6370 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Implemented BAN command to the server, in silcd/command.[ch].
6374 * Removed the BAN and INVITE_LIST modes from the CMODE command
6377 * Added function silc_string_match to regex match two strings.
6378 Affected files lib/silcutil/silcutil.[ch].
6380 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Redefined parts of the SilcChannelEntry in the server to support
6383 the new ban and invite lists.
6385 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * Redefined the INVITE command. The same command can be used to
6388 invite individuals to the channel but also to manage the invite
6389 list of the channel (to add to and remove from the invite list).
6390 Updated the protocol specs.
6392 * Added new command SILC_COMMAND_BAN that can be used to manage
6393 the ban list of the channel. Updated the protocol specs.
6395 * Removed the channel modes: the SILC_CMODE_BAN and the
6396 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6397 in the CMODE command. The equivalent features are now available
6398 using INVITE and BAN commands. Updated the protocol specs.
6400 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6401 in the network about change in the current ban list. The notify
6402 type is not used by the client.
6404 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6405 support the invite lists.
6407 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Added new function silc_string_regexify that converts string
6410 including wildcard characters into regex string that can
6411 be used by the GNU regex library. Added into the file
6412 lib/silcutil/silcutil.[ch].
6414 Added silc_string_regex_combine to combine to regex strings
6415 into one so that they can be used as one regex string by
6416 the GNU regex library. Added into the file
6417 lib/silcutil/silcutil.[ch].
6419 Added silc_string_regex_match to match two strings. It returns
6420 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6422 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6424 * Imported GNU regex to the soruce tree into lib/contrib.
6425 Fixed some compiler warning from the regex.c.
6427 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Fixed MOTD command in the server to work in router environment.
6431 * Fixed the MOTD command in the client library to support
6432 the server argument in the command.
6434 * Added `nickname_len' argument to the silc_idlist_add_client
6435 in the server, as the `nickname' argument may be binary data
6438 * Added silc_idlist_get_channels to return all channels from
6441 * Implemented LIST command to the server. Affected file is
6444 * Implemented the LIST command to the client library and on the
6447 * Added [<user count>] argument to the LIST command reply.
6448 With private channels the user count is not shown.
6450 * Updated TODO and README.
6452 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * The client entry's data.registered must be TRUE even with
6455 global client entry on global client list. The data.registered
6456 is used to check whether the client is anymore in the network,
6457 for example with WHOWAS command so it must be valid.
6459 * Fixed the WHOWAS command in the server. It now actually works
6460 in router environment. Added function into silcd/command_reply.c
6461 silc_server_command_reply_whowas_save.
6463 * Added silc_idlist_purge function to the silcd/idlist.c
6464 to periodically purge the ID Cache.
6466 * Fixed INFO command in the server. It works now in router
6467 environment. Added <server name> argument to the INFO command
6468 reply. Updated the protocol specs.
6470 * Fixed minor bug in silc_idcache_purge to not purge if the
6471 expire value is zero.
6473 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6474 they were buggy because of the WHOWAS information.
6476 * Fixed local command MSG to handle the async resolving of
6477 the remote client properly. It used to fail the first MSG.
6478 Affected file silc/local_command.c.
6480 * Added `data_len' field to SilcIDCache context.
6482 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Update TODO. Todo in commands in the server.
6486 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6489 used by routers as broadcast packet to inform other routers
6490 about the changed user mode.
6492 Implemented the notify handling in the server. Affected file is
6493 silcd/packet_receive.c. Added the function
6494 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6496 * Added new generic Channel Payload and deprecated the New Channel
6497 Payload. The New Channel Payload is now the generic Channel
6500 * Added new argument `mode' to the silc_server_send_new_channel
6501 as it is required in the Channel Payload now.
6503 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6504 and created a new and real SilChannelPayload to represent the
6505 new generic Channel Payload. Implemented the encode/decode
6506 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6508 * Added silc_server_get_client_channel_list to return the list
6509 of channels the client has joined for WHOIS command reply.
6510 Affected file silcd/server.[ch].
6512 * Implemented the channel list sending in the WHOIS command reply
6513 in server and in the client.
6515 Implemented the channel list displaying on the user interface
6516 as well. Affected file silc/client_ops.c.
6518 * Added silc_channel_payload_parse_list to parse list of Channel
6519 Payloads. It returns SilcDList list of SilcChannelPayloads.
6520 Client for example can use this function to parse the list of
6521 channels it receives in the WHOIS command reply. The caller
6522 must free the list by calling silc_channel_payload_list_free.
6523 Affected files lib/silccore/silcchannel.[ch].
6525 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Added one new argument <user mode> to the WHOIS command reply
6528 to return the mode of the user in SILC. Updated the protocol
6531 Implemented it to the server and client.
6533 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Fixed the mode printing on the user interface on joining.
6536 Affected file silc/client_ops.c.
6538 * Implemented the UMODE command and user modes in general to the
6539 client library and to the user interface.
6541 * Implemented the UMODE command to the server.
6543 * The server now sends UNKNOWN_COMMAND error status if client sends
6544 unknown command. Affected file silcd/command.c.
6546 * All server commands now handle the command identifier the right
6547 way when sending the command reply to the client. The client can
6548 use to identify the command replies with the identifier.
6550 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Added silc_server_get_client_route to resolve the route to
6553 the client indicated by the client ID. Affected file is
6556 * Added silc_server_relay_packet as general function to relay
6557 packet to arbitrary destination. This deprecates functions
6558 like _send_private_message_key, _relay_notify etc. Affected
6559 file is silcd/packet_send.[ch].
6561 Removed silc_server_send_key_agreement,
6562 silc_server_send_private_message_key and
6563 silc_server_packet_relay_notify functions from the file
6564 silcd/packet_send.[ch].
6568 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6569 server. Affected file silcd/packet_receive.[ch].
6571 * Implemented the KILL command to the client. Implemented the
6572 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6573 Affected files lib/silcclient/command[_reply].c and
6574 lib/silcclient/client_notify.c. Implemented the KILL notify
6575 printing in the user inteface.
6577 * Fixed a lot silc_parse_nick memory leaks from the client
6578 library in the file lib/silcclient/command.c.
6580 * Changed the silc_server_send_notify_on_channels's `sender'
6581 argument from SilcSocketConnection to SilcClientEntry to
6582 check the sender as entry and not as connection object and not
6583 to send to the client provided as argument. The affected file
6584 is silcd/packet_send.[ch].
6586 * The notify packets that are destined directly to the client used
6587 to not to be processed by the server. Now changed that and the
6588 server processes all notify packets. After relaying the packet
6589 to the client the notify packet is processed in the server.
6591 * The silc_server_free_client_data now checks whether there is
6592 pending outgoing traffic for the client and purges the data to
6593 the network before removing the client entry.
6595 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6598 an client is killed from the SILC Network. Updated the protocol
6601 Added new function silc_server_send_notify_killed to the
6602 silcd/packet_send.[ch].
6604 * Added function silc_server_packet_relay_notify to relay notify
6605 packets that are destined directly to a client. In this case
6606 the server does not process the notify packets but merely relays
6607 it to the client. Affected file silcd/packet_send.[ch].
6609 Added also silc_server_packet_process_relay_notify to check
6610 whereto relay the notify. Affected file is
6611 silcd/packet_receive.[ch].
6613 * Implemented the KILL command to the server.
6617 * Added the backup schema desgined last fall to the protocol
6618 specs for everyone to see. The specification is in the
6619 *-spec-xx.txt draft and the packet type definitions for the
6620 backup routers is in *-pp-xx.txt draft. Thusly, added also
6621 new packet type SILC_PACKET_CELL_ROUTERS.
6623 * A big security problem in the implementation discovered. The
6624 signoff of an client did not cause new channel key generation
6625 which it of course should've done. The channel keys must be
6626 always re-generated when client leaves (or signoffs) the channel.
6627 The silc_server_remove_from_channels funtion now handles
6628 the channel key re-generation.
6630 * Added `sender' argument to the silc_server_send_notify_on_channels
6631 to not to send the client provided as argument. Affected file
6632 silcd/packet_send.[ch].
6634 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Implemented OPER and SILCOPER commands into the server and
6639 * Added silc_auth_verify and silc_auth_verify_data to verify
6640 the authentication directly from the authentication payload.
6641 It supports verifying both passphrase and public key based
6642 authentication. Affected file lib/silccore/silcauth.[ch].
6644 * Added `hash' field to the SilcIDListData structure. It is the
6645 hash negotiated in the SKE protocol. Affected file is
6648 * Slight redesigning of the SilcAuthPayload handling routines.
6649 Do not send SilcPKCS but SilcPublicKey as argument.
6651 * Implemented the public key authentication support to the
6652 serverconfig. The public key is loaded from the provided path
6653 and saved as authentication data to void * pointer. Thus,
6654 changed the unsigned char *auth_data to void *auth_data;
6656 * Fixed SHUTDOWN command to send the reply before the server
6657 is shutdown. :) Affected file silcd/command.c.
6659 * Fixed fatal bug in CONNECT command. The hostname was invalid
6660 memory and server crashed. Affected file silcd/command.c.
6662 * Fixed fatal bug in CLOSE command. The server_entry became
6663 invalid but was referenced later in the command. Affected file
6666 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Fixed fatal bug in failure packet handling. Server ignored
6669 the failure and thus crashed when it came.
6673 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6676 that the command may be executed only once in (about) 2 seconds.
6677 The old SILC_CF_LAG flag is same but allows command bursts up
6678 to five before limiting.
6680 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6681 server code. Various commands now includes the CF_LAG_STRICT
6682 flag to disallow any kind of miss-use of the command.
6684 * Fixed the silc_buffer_unformat to not to allocate any data
6685 if the length of the data is zero. It used to allocate the
6686 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6688 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6690 * Changed the format of AdminConnection configuration section
6691 in the server. Added username of the admin to the format.
6692 Affected files silcd/serverconfig.[ch].
6694 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6695 to return admin configuration data by host, username and/or
6698 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Implemented WHOWAS command to the server. Added the functions:
6702 silc_server_command_whowas_parse,
6703 silc_server_command_whowas_send_reply,
6704 silc_server_command_whowas_from_client and
6705 silc_server_command_whowas_from_server
6707 * Added <Client ID> argument to the WHOWAS command reply. Updated
6708 the protocol specs accordingly.
6710 * Implemented WHOWAS command and command_reply to the client
6713 Implemented the WHOWAS printing on the user interface.
6715 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6717 * Added new argument to the WHOWAS command reply, the real name.
6718 It is an optional argument. Updated the protocol specs.
6720 * Added SilcIDCacheDestructor callback that is registered when
6721 the SilcIDCache is allocated. The callback is called when
6722 an cache entry in the ID Cache expires, or is purged from the
6723 cache. Added into lib/silccore/idcache.[ch].
6725 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6726 to destruct the client entries when the cache entry expires.
6727 Other ID Cache's in server and in the client library ignores
6730 * If the ID Cache entry's `expire' field is zero then the entry
6731 never expires. Added boolean `expire' argument to the
6732 silc_idcache_add function in the lib/silccore/idcache.[ch].
6733 If it is TRUE the default expiry value is used.
6735 * Added silc_server_free_client_data_timeout that is registered
6736 when client disconnects. By default for 5 minutes we preserve
6737 the client entry for history - for WHOWAS command.
6739 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Added support to the server to enforce that commands are not
6742 executed more than once in 2 seconds. If server receives
6743 commands from client more frequently, timeout is registered
6744 to process the commands. Affected file silcd/command.c.
6745 Added new function silc_server_command_process_timeout.
6747 * Changed NICK_NOTIFY handling in client library to check that
6748 if the client's nickname was changed, so there is no need to
6749 resolve anything from the server.
6751 * Removed error printing from the WHOIS and IDENTIFY commands.
6752 If error occurs then it is ignored silently in the client library.
6753 The application, however, may map the received error to
6754 human readable error string. The application currently maps
6755 the NO_SUCH_NICKNAME error to string.
6757 * Made the command status message public to the application. Moved
6758 them from lib/silcclient/command_reply.c to
6759 lib/silcclient/command_reply.h. The application can map the
6760 received command status to the string with the
6761 silc_client_command_status_message function.
6763 * Added check to the server to check that client's ID is same
6764 as the Source ID in the packet the client sent. They must
6767 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Added dist-bzip hook to the Makefile.am to make bzip2
6770 compressed distributions.
6772 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Server now enforces the maximum length for the nickname and
6775 the channel as protocol specification dictates. 128 bytes for
6776 nickname and 256 bytes for channel name.
6778 * Moved the WHOIS printing to the application. The client libary
6779 does not print out the WHOIS information anymore, the application
6780 must do it. Renamed silc_client_command_reply_whois_print to
6781 the silc_client_command_reply_whois_save.
6783 The client's idle time is also sent to the application now, and
6784 the idle is shown on screen.
6786 * Added silc_client_command_reply_identify_save to save the
6787 received IDENTIFY entries.
6789 * Do not check for channel private keys in message sending and
6790 reception if the channel does not have the PRIVKEY mode set.
6791 Affected file lib/silclient/client_channel.c.
6793 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6796 just surfaced after chaning the JOIN procedure.
6798 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added silc_client_get_clients_by_list to get client entries
6801 from Client ID list, that is returned for example by JOIN
6802 and USERS command replies. The application should use this
6803 function for example when JOIN command reply is received to
6804 resolve the clients already on the channel (library does not
6805 do that anymore as USERS command reply is not used in the JOIN
6806 procedure anymore). Affected files lib/silcclient/silcapi.h and
6807 lib/silcclient/idlist.c.
6809 * JOIN command reply and USERS command reply returns now SilcBuffer
6810 pointers instead of unsigned char pointers when returning
6811 the client list and mode list.
6813 * Added <Client ID> argument to the JOIN command reply, mainly
6814 for the server to identify for which client the command was
6815 originally sent. Updated protocol specs accordingly.
6817 * Added SilcDlist private_key pointer to the SilcChannelEntry
6818 in the client to support the channel private keys. Affected
6819 file is lib/silcclient/idlist.h.
6821 * Added SilcChannelPrivateKey argument to the function
6822 silc_client_send_channel_message so that application can choose
6823 to use specific private ke if it wants to. If it is not provided,
6824 the normal channel key is used, unless private keys are set.
6825 In this case the first (key that was added first) is used
6826 as the encryption key.
6828 * Implemented the support for channel private key handling.
6829 Implemented the following functions:
6831 silc_client_add_channel_private_key,
6832 silc_client_del_channel_private_keys,
6833 silc_client_del_channel_private_key,
6834 silc_client_list_channel_private_keys and
6835 silc_client_free_channel_private_keys
6837 Affected file lib/silcclient/client_channel.c.
6839 * Added the support for the private keys in the channel message
6840 sending and encryption and in the message reception and
6841 decryption. Affected funtions are
6842 silc_client_send_channel_message and silc_client_channel_message.
6844 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Added SKE's key verify callback to the client library's
6847 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6849 * Removed the statement that server (or router) must send USERS
6850 command reply when joining to the channel so that the client
6851 knows who are on the channel. Instead, the client list and
6852 client's mode list is now sent in the JOIN command reply to the
6853 client who joined channel. This is better solution.
6855 * Added function silc_server_get_users_on_channel and function
6856 silc_server_save_users_on_channel to the silcd/server.[ch].
6858 * Removed function silc_server_command_send_users from the
6861 * Do not show topic on the client library anymore. The topic is
6862 sent in the command reply notify to the application and the
6863 application must show the topic now.
6865 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Added client searching by nickname hash into the IDENTIFY and
6868 WHOIS commands in the server as they were clearly missing from
6869 them. Affected file is silcd/command.c.
6871 * Fixed a bug in private message receiving in the client library.
6872 The remote ID was freed and it wasn't supposed, now it is
6875 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Minor fix to the channel payload; allocate the data area, as it
6878 needs to be of specific length.
6880 * If the key agreement port is zero then the operating
6881 system will define the bound port. Affected files are
6882 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6884 * Added new function silc_channel_payload_decrypt into the file
6885 lib/silccore/silcchannel.[ch].
6887 * Moved the channel message etc, check from silc_packet_decrypt
6888 to applications. The library calls now a generic
6889 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6890 when the packet is either normal or special. This was done to
6891 allow more wide range of checking that was not allowed when
6892 the code was in library. Now applications can do virtually any
6893 checks to the packet and return to the library the decision how
6894 the packet should be processed. Affected files are
6895 lib/silccore/silcpacket.[ch].
6897 Added silc_server_packet_decrypt_check to the server and
6898 silc_client_packet_decrypt_check to the client library.
6900 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6901 to send with specified source and destination information.
6903 * Channel message delivery between routers was broken after the
6904 channel key distribution was fixed earlier. The channel key
6905 was used be to distributed to other routers as well which is not
6906 allowed by the protocol. Now this is fixed and channel keys
6907 really are cell specific and the channel message delivery between
6908 routers comply with the protocol specification.
6910 * Fixed various commands in server to check also the global list
6911 for the channel entry and not just the local list. The affected
6912 file silcd/command.c.
6914 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Added assert()s to buffer formatting and unformatting routines
6917 to assert (if --enable-debug) when error occurs. Affected
6918 file: lib/silcutil/silcbuffmt.c.
6920 * Changed to auto-reconnect to check whether the remote host is
6921 router and register the re-connect timeout if it is. It used
6922 to check that whether we are normal server, but router must do
6923 auto-reconnect with another router as well. Affected file
6926 * Removed the [<key len>] option from CMODE command as the cipher
6927 name decides the key length, nowadays. See the defined ciphers
6928 from the protocol specification.
6930 * Added [<hmac>] option to the CMODE command to define the HMAC
6931 for the channel. Added SILC_CMODE_HMAC channel mode.
6933 * Added [<hmac>] option for the JOIN command so that user can
6934 select which HMAC is used to compute the MACs of the channel
6937 * Added Hmac field to the Channel Message Payload. The integrity
6938 of plaintext channel messages are now protected by computing
6939 MAC of the message and attaching the MAC to the payload. The
6940 MAC is encrypted. Now, it is clear that this causes some
6941 overhead to the size of the packet but rationale for this is that
6942 now the receiver can verify whether the channel message decrypted
6943 correctly and also when private keys are set for the channel the
6944 receiver can decrypt the packet with several keys and check from
6945 the MAC which key decrypted the message correctly.
6947 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6948 lib/silccrypt/silccipher.[ch].
6950 * Added silc_hash_len to return the digest length into the
6951 lib/silcrypt/silchash.[ch].
6953 * Rewrote parts of Silc Channel Payload interface in the
6954 lib/silccore/silcchannel.[ch]. The encode function now also
6955 encrypts the packet and parse function decrypts it.
6957 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Fixed a minor formatting bug in the SKE's key material processing.
6960 It actually might have processed the keys wrong way resulting
6963 * Redefined the mandatory HMAC algorithms and added new algorithms.
6964 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6965 and hmac-md5 truncated to 96 bits. The mandatory is now
6966 hmac-sha1-96. Rest are optional (including the one that used
6967 to be mandatory). Rationale for this is that the truncated HMAC
6968 length is sufficient from security point of view and can actually
6969 make the attack against the HMAC harder. Also, the truncated
6970 HMAC causes less overhead to the packets. See the RFC2104 for
6973 * Added new [hmac] configuration section. The SKE used to use
6974 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6975 is of course wrong. The official names that must be proposed in
6976 the SKE are the ones defined in the protocol specification
6977 (hmac-sha1-96 for example). The user can configure any hmac
6978 using any hash function configured in the [hash] section. At
6979 least, the mandatory must be configured.
6981 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6983 * Added HMAC list to the SKE proposal list. It has now both
6984 hash algorithm list and HMAC list. This makes the protocol
6985 incompatible with previous versions. The SKE now seems to work
6986 the way it is supposed to work, for the first time actually.
6988 * Defined plain Hash algorithms to the protocol specification.
6991 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Implemented support for key agreement packets into the server.
6994 Added functions silc_server_key_agreement and
6995 silc_server_send_key_agreement. Other than these functions,
6996 server has nothing to do with this packet.
6998 * Added support for private message key packets into the server.
6999 Added functions silc_server_private_message_key and
7000 silc_server_send_private_message_key.
7004 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7005 called in the protocol's final callback instead in the END
7006 protocol state. This makes a little more sense and in the same
7007 time in client we can use the same protocol routines for normal
7008 key exchange and to key agreement packet handling as well.
7010 * Added to both client's and server's KE protocol context the
7011 SilcSKEKeyMaterial pointer to save the key material. We will
7012 bring the key material to the protocol's final callback by doing
7013 this. The final callback must free the key material.
7015 * Added SKE's packet_send callback into client's KE protocol
7016 context so that the caller can choose what packet sending function
7017 is used. This way we can use different packet sending when
7018 doing normal SKE when doing key agreement packet handling (in
7019 the key agreement packet handling we do not want to encrypt
7022 * Implemented the responder side of the key agreement routines
7023 in the client. The client can now bind to specified port and
7024 accept incoming key negotiation. The key material is passed
7025 to the application after the protocol is over.
7027 * Implemented the processing of incoming Key Agreement packet
7028 in the client. Added function silc_client_key_agreement to
7031 * Implemented the intiator side of the key agreement routines
7032 in the client. The client can now initiate key agreement with
7033 another remote client. The key material is passed to the
7034 application after the protocol is over.
7036 * Created client_keyagr.c to include all the key agreement
7039 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7040 SILC_TASK_CALLBACK except that it is not static.
7042 * Created client_notify.c and moved the Notify packet handling
7043 from the client.[ch] into that file.
7045 * Created client_prvmsg.c and moved all private message and
7046 private message key routines from the client.[ch] into that file.
7048 * Create client_channel.c and moved all channel message and
7049 channel private key routines from the client.[ch] into that file.
7051 * Changed silc_client_get_client_by_id_resolve to resolve with
7052 WHOIS command instead of IDENTIFY command, in the file
7053 lib/silclient/idlist.c.
7055 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Implemented the SKE's responder side to the Client library.
7059 * When FAILURE is received to the protocol do not trust it
7060 blindly. Register a timeout to wait whether the remote closes
7061 the connection as it should do it, only after that process the
7062 actual failure. This was changed to both client and server.
7064 * Added client_internal.h to include some of the structures
7065 there instead of client.h in lib/silcclient/.
7067 * Added function silc_task_unregister_by_callback to unregister
7068 timeouts by the callback function.
7070 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Some "Incomplete WHOIS info" errors has been appearing on the
7073 log files. Took away the entry->userinfo check from WHOIS
7074 reply sending. The entry->userinfo is now " " if client did not
7075 provide one. I thought this was fixed earlier but something
7076 is wrong still. Let's see if the error still appears.
7078 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Fixed a minor bug in the login when the channel key is
7081 re-generated in the server. It used to generate the key in
7082 wrong order and thus caused problems in the channel traffic.
7084 * Fixed a minor bug in channel key distsribution after
7085 KICK command. The key was not sent to the router even though
7088 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Added silc_ske_process_key_material_data as generic routine
7091 to process any key material as the SILC protocol dictates. The
7092 function is used by the actual SKE library but can be used by
7093 applications as well. This relates to the private message keys
7094 and the channel private keys since they must be processed the
7095 same way the normal SILC session keys. The protocol dictates
7096 this. Affected files: lib/silcske/silcske.[ch].
7098 Added also silc_ske_free_key_material to free the
7099 SilcSKEKeyMaterial structure.
7101 * Defined silc_cipher_set_key function to set the key for
7102 cipher without using the object's method function. The affected
7103 files: lib/silccrypt/silccipher.[ch].
7105 * Implemented silc silc_client_add_private_message_key,
7106 silc_client_add_private_message_key_ske,
7107 silc_client_del_private_message_key,
7108 silc_client_list_private_message_keys and
7109 silc_client_free_private_message_keys functions in the
7112 Added functions silc_client_send_private_message_key to send
7113 the Private Message Key payload and silc_client_private_message_key
7114 to handle incoming Private Message Key payload.
7116 * Added Cipher field to the Private Message Key payload to set
7117 the cipher to be used. If ignored, the default cipher defined
7118 in the SILC protocol (aes-256-cbc) is used.
7120 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Removed lib/silcclient/ops.h file.
7124 Redefined parts of the SILC Client Library API. Created new
7125 file silcapi.h that deprecates the ops.h file and defines the
7126 published Client Library API. Defined also private message key
7127 API and channel private key API into the file.
7129 This is the file that the application must include from the
7130 SILC Client Library. Other files need not be included by
7131 the application anymore.
7133 * Added new key_agreement client operation callback and also
7134 defined the Key Agreement library API for the application.
7136 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7139 is used by clients to request key negotiation between another
7140 client in the SILC network. If the negotiation is started it
7141 is performed using the SKE protocol. The result of the
7142 negotiation, the secret key material, can be used for example
7143 as private message key.
7145 Implemented the Key Agreement payload into the files
7146 lib/silccore/silauth.[ch].
7148 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Redefined ciphers for the SILC protocol. Added some new ciphers
7151 and defined the key lengths for the algorithms. Changed the
7152 code accordingly. The default key length is now 256 bits.
7154 * Fixed SKE key distribution function silc_ske_process_key_material
7155 when the key length is more than 128 bits. The default key
7156 length in SILC is now 256 bits.
7158 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7159 to indicate unsupported algorithm.
7161 * Renamed rijndael.c to aes.c and all functions as well.
7163 * Fixed a long standing channel key setting bug in client library.
7164 Weird that it has never surfaced before.
7166 * Fixed bug in channel deletion. If the entire channel is removed
7167 then it must also delete the references of the channel entry
7168 from the client's channel list as the client's channel entry and
7169 the channel's client entry share same memory.
7171 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Implemented CONNECT and SHUTDOWN commands in the client.
7175 * Implemented CLOSE command to the client.
7177 * Added the function silc_idlist_find_server_by_name into the
7178 files silcd/idlist.[ch].
7180 Added the function silc_idlist_find_server_by_conn into the
7181 files silcd/idlist.[ch].
7183 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * DIE command was renamed to SHUTDOWN. Updated the both code
7188 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7189 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7191 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7194 * Added function silc_server_create_connection function to create
7195 connection to remote router. My server implementation actually
7196 does not allow router to connect to normal server (it expects
7197 that normal server always initiates the connection to the router)
7198 so the CONNECT command is only good for connecting to another
7201 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7204 or some other client was kicked from the channel.
7206 Implemented the handling of the notify type to both client
7209 Implemented silc_server_send_notify_kicked to send the KICKED
7210 notify. It is used to send it to the server's primary router.
7212 * Implemented the KICK command into server and client.
7214 * Added `query' argument to the silc_idlist_get_client function
7215 to indicate whether to query the client from server or not if
7218 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7219 to indicate that the client is not channel founder.
7223 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Removed the rng context from SilcPacketContext structure and
7226 changed that the packet routine uses the Global RNG API.
7228 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added support for quit message that client can "leave" on the
7231 channel when it quits the SILC. It is ditributed inside the
7232 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7234 Added silc_server_free_client_data that will take the
7235 signoff message as argument.
7237 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7239 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Updated parts of the protocol specification to keep it up
7244 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7247 payloads in one packet.
7249 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7250 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7251 use now the new List flag.
7253 * Also deprecated the following packet types: REPLACE_ID,
7254 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7256 * Added list support for Notify packet in server.
7258 * Added silc_server_send_notify_channel_change to send the
7259 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7260 the silc_server_send_replace_id.
7262 * Added silc_server_send_notify_nick_change to send the
7263 NICK_CHANGE notify type. Deprecates the function
7264 silc_server_send_replace_id.
7266 * Added silc_server_send_notify_join to send the JOIN notify type.
7267 Deprecates the function silc_server_send_new_channel_user.
7269 * Added silc_server_send_notify_leave to send LEAVE notify type.
7270 Deprecates the function silc_server_send_remove_channel_user.
7272 * Added silc_server_send_notify_cmode and
7273 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7274 types. Deprecates the silc_server_send_set_mode function.
7276 * Added SERVER_SIGNOFF notify type to indicate that server has
7277 quit. This means that all clients on the channel from that
7278 server will drop. This can be also used when netsplit happens.
7280 Deprecated REMOVE_ID packet type since it is not needed anymore
7283 Added silc_server_send_notify_server_signoff to send the
7284 SERVER_SIGNOFF notify type. Deprecates the function
7285 silc_server_send_remove_id.
7287 Added also silc_server_send_notify_signoff to send the
7288 SIGNOFF notify type.
7290 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7291 SILC protocol from this day on. Changed the protocol
7292 specification as well.
7294 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7295 notify type. It is used between routers to notify about
7296 topic changes on a channel.
7298 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7301 * Partly updated the protocol specification to comply with the
7302 changes now made. It is still though a bit outdated.
7304 * The JOIN notify type now takes one extra argument <Channel ID>.
7305 The packet used to be destined to the channel but now the
7306 JOIN type may be sent as list thus it is impossible to
7307 destine it to any specific channel. By adding this argument
7308 it is again possible.
7310 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Added CREDITS file. The CHANGES and CREDITS file will appear
7313 in the distribution as well.
7315 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7318 types in the server's silcd/packet_receive.c.
7320 * Implemented CMODE and CUMODE to work in router environment.
7322 * Fixed minor encoding and decoding buglet from the
7323 lib/silccore/silcmode.c.
7325 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7328 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7330 * Changed all SilcConfigServer* and silc_config_server* to
7331 SilcServerConfig* and silc_server_config*, respectively.
7334 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Associated the ID (client or server ID) to the Authentication
7337 Payload to avoid any possibility of forging. Updated the
7338 protocol specification and the code accordingly.
7340 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * The RSA key length is now save to the RsaKey context in the
7343 key generation process in lib/silccrypt/rsa.c. The key length
7344 is now used to figure out the maximum size of the block allowed
7345 to be encrypted/signed.
7347 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7348 is equivalent to the silc_mp_mp2bin but does not allocate any
7351 * Changed silc_mp_mp2bin API to take length argument. If it is
7352 non-zero then the buffer is allocated that large. If zero, then
7353 the size is approximated using silc_mp_sizeinbase, which however
7356 * Created Global RNG API which is global RNG that application can
7357 initialize. After initializing, any routine anywhere in the
7358 code (including library) can use RNG without allocating a new
7359 RNG object. This was done to allow this sort of use of the
7360 RNG in code that has no chance to allocate RNG object. All
7361 applications currently allocate this and many routines in the
7362 library use this. Affected file lib/silccrypt/silcrng.[ch].
7364 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7365 it to use the Global RNG API.
7367 * Defined Authentication Payload into protocol specification that
7368 is used during SILC session to authenticate entities. It is
7369 used for example by client to authenticate itself to the server
7370 to obtain server operator privileges.
7372 Implemented this payload into the lib/silccore/silcauth.[ch].
7373 Implemented also routines for public key based authentication
7374 as the new protocol specification dictates.
7376 Moved definitions of different authentication methods from
7377 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7379 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7380 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7381 silc_pkcs_verify_with_hash functions into the file
7382 lib/silccrypt/silcpkcs.[ch].
7384 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * The client entry's userinfo pointer must be always valid.
7387 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7388 will fail since it requires the userinfo. Now, the userinfo
7389 is allocated as "" if actual userinfo does not exist. Actually,
7390 it must exist and it is totally Ok to drop client connections
7391 that does not announce the userinfo. However, we will make
7392 this workaround for now.
7394 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7395 to return the remote port by socket.
7397 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7400 SILC_SERVER_PENDING_EXEC and added an new macro
7401 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7402 data or when error occurs while processing the pending command.
7404 Added new argument `destructor' into silc_server_command_pending
7405 and to the SilcServerCommandPending object. This destructor is
7406 now called after calling the pending callback or if error occurs
7407 immediately. If error occurs the actual pending callback won't
7408 be called at all - only the destructor. The destructor may be
7409 NULL if destructor is not needed.
7411 All this applies for client library code as well. Similar
7412 changes were made there as well for the pending commands.
7414 In the client, the application must now allocate the
7415 SilcClientCommandContext with the silc_client_command_alloc
7418 * Added reference counter to the SilcServerCommandContext. Added
7419 function silc_server_command_alloc and silc_server_command_dup
7422 Same type of functions added to the client library for the same
7425 * Removed the cmd_ident from IDListData away since it is now
7426 global for all connections. It is the command identifier used
7427 in command sending and with pending commands. The affected file
7430 * Added reference counter to the SilcSocketConnection objecet to
7431 indicate the usage count of the object. The object won't be
7432 freed untill the reference counter hits zero. Currently only
7433 server uses this, and client ignores it. The client must be
7434 set to use this too later. The affected files are
7435 lib/silccore/silcsockconn.[ch]. Added also the function
7436 silc_socket_dup to increase the reference counter.
7438 This was mainly added because it is possible that the socket
7439 is removed underneath of pending command or other async
7440 operation. Now it won't be free'd and proper DISCONNECTING
7441 flags, etc. can be set to avoid sending data to connection that
7442 is not valid anymore.
7444 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7445 the connection. After that it sets SILC_SET_DISCONNECTED.
7446 It is, however, possible that the socket data is not still freed.
7447 The silc_server_packet_process now checks that data is not
7448 read or written to connection that is DISCONNECTED. The socket
7449 get's freed when the reference counter hits zero.
7451 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Changed the client operation API: channel_message operation's
7454 `sender' is now the client entry of the sender, not the nickname
7455 and the `channel' is the channel entry, not the channel name.
7457 In the private_message operation the `sender' is now also the
7458 client entry of the sender not the nickname.
7460 Affected file is lib/silcclient/ops.h and all applications
7461 using the client operations.
7463 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Moved the calling of ops->connect() from connect_to_server_final
7466 into receive_new_id functin since that is the point when the
7467 client is actually allowed to send traffic to network. The
7468 affected file is lib/silcclient/client.c.
7470 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7473 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7474 (if needs broadcasting) instead of broadcasting the packets one
7475 by one which would make a burst in the network traffic.
7477 * Added `broadcast' argument to the functions in silcd/server.[ch]
7478 silc_server_create_new_channel[_with_id] to indicate whether
7479 to send New Channel packet to primary router.
7481 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Added new function into the silcd/server.[ch] files:
7484 silc_server_create_new_channel_with_id to create new channel with
7485 already existing Channel ID.
7487 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7488 lib/silccore/silcpacket.h. This packet is used t send list of
7489 Set Mode payloads inside one packet. Server uses this to set
7490 the modes for the channels and clients on those channels, that it
7491 announced to the router when it connected to it. The protocol
7492 specification has been updated accordingly.
7494 * The silc_server_new_channel did not handle the packet coming
7495 from normal server as it normally does not send that. However,
7496 when it announces its channels it does send it. Implemented
7497 the support for that.
7499 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7500 into the file lib/silccore/id.h.
7502 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7504 * Fixed memory leaks in the functions silc_idlist_del_client,
7505 silc_idlist_del_channel and silc_idlist_del_server in the file
7506 silcd/idlist.c. All of those leaked like a sieve.
7508 * Fixed some small memory leaks in the client's function
7509 silc_client_notify_by_server.
7511 * Added functions into silcd/server.c: silc_server_announce_clients,
7512 silc_server_announce_channels and silc_server_announce_server.
7513 These functions are used by normal and router server to announce
7514 to its primary router about clients, channels and servers (when
7515 router) that we own. This is done after we've connected to the
7518 These functions effectively implements the following packet types:
7519 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7520 and SILC_PACKET_NEW_ID_LIST.
7522 * Added new functions into the silcd/packet_receive.[ch]:
7523 silc_server_new_id_list, silc_server_new_channel_list and
7524 silc_server_new_channel_user_list to handle the incoming
7525 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7527 * Added support of changing Channel ID in the function
7528 silc_server_replace_id. If the server that announces a channel
7529 to the router already exists in the router (with same name but
7530 with different Channel ID), router is responsible to send
7531 Replace ID packet to the server and force the server to change
7532 the Channel ID to the one router has.
7534 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7535 client that the Channel ID has been changed by the router. The
7536 normal server sends this to the client. Client must start using
7537 the new Channel ID as the channel's ID.
7539 Implemented handling of this new type into lib/silcclient/client.c
7540 into the function silc_client_notify_by_server.
7542 * Added new function silc_idlist_replace_channel_id into the files
7543 silcd/idlist.[ch] to replace the Channel ID.
7545 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Call silc_server_command_identify_check always when processing
7548 the IDENTIFY command in silcd/command.c
7550 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7552 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7553 send keepalive packets. The packet can be sent by clients,
7554 servers and routers.
7556 Added function silc_socket_set_heartbeat into the file
7557 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7558 If not set, the heartbeat is not performed. The actual
7559 heartbeat is implemented in the low level socket connection
7560 library. However, application is responsible of actually
7563 Added silc_server_send_heartbeat to send the actual heartbeat
7564 packet into silcd/packet_send.[ch]. Server now performs
7565 keepalive with all connections.
7567 * Added silc_task_get_first function into lib/silcutil/silctask.c
7568 to return the timeout task with shortest timeout. There was a bug
7569 in task unregistration that caused problems. TODO has been
7570 updated to include that task system must be rewritten.
7572 * The client library will now resolve the client information when
7573 receiving JOIN notify from server for client that we know but
7574 have incomplete information.
7576 * Rewrote parts of silc_server_remove_from_channels and
7577 silc_server_remove_from_one_channel as they did not remove the
7578 channel in some circumstances even though they should've.
7580 * Encryption problem encountered in server:
7582 The LEAVE command used to send the Channel Key packet to the
7583 router immediately after generating it. However, the code
7584 had earlier sent Remove Channel user packet but not immediately,
7585 ie. it was put to queue. The order of packets in the router
7586 was that Channel Key packet was first and Remove Channel User
7587 packet was second, even though they were encrypted in the
7588 reverse order. For this reason, MAC check failed. Now, this
7589 is fixed by not sending the Channel Key packet immediately but
7590 putting it to queue. However, this is more fundamental problem:
7591 packets that are in queue should actually not be encrypted
7592 because packets that are sent immediately gets encrypted
7593 actually with wrong IV (and thus MAC check fails). So, packets
7594 that are in queue should be encrypted when they are sent to
7595 the wire and not when they put to the queue.
7597 However, the problem is that the current system has not been
7598 designed to work that way. Instead, the packet is encrypted
7599 as soon as possible and left to the queue. The queue is then
7600 just purged into wire. There won't be any fixes for this
7601 any time soon. So, the current semantic for packet sending
7604 o If you send packet to remote host and do not force the send
7605 (the packet will be in queue) then all subsequent packets to the
7606 same remote host must also be put to the queue. Only after the
7607 queue has been purged is it safe again to force the packet
7610 o If you send all packets immediately then it safe to send
7611 any of subsequent packets through the queue, however, after
7612 the first packet is put to queue then any subsequent packets
7613 must also be put to the queue.
7615 Follow these rules and everything works fine.
7617 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Added new function silc_server_remove_clients_by_server to
7620 remove all client entries from ID list when the server connection
7621 is lost. In this case it is also important to invalidate all
7622 client entires as they hold the invalid server entry. This
7623 fixes fatal bug when server has lost connection and will reconnect
7626 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Made some sanity checks to silc_server_daemonise like to check
7629 whether the requested user and group actually exists.
7631 * Added sanity check to SKE's silc_ske_responder_finish to check
7632 that the public and private key actually is valid.
7634 * Invalidate the client's nickname when receiving Replace ID
7635 packet and the Client ID is being replaced. This means that the
7636 server will query the nickname if someone needs it (client)
7639 * Sort the ID Cache in client library when the ID Cache data
7640 has changed (needs sorting).
7642 * Do not allow for SILC client to create several connections to
7643 several servers. The client does not support windows right now
7644 and generating multiple connections causes weird behaviour.
7646 Irssi-silc client does support windows and can handle several
7647 connections without problems, see: www.irssi.org and SILC plugin.
7649 * Fixed some places where client was added to the IDList. The
7650 rule of thumb is following (in order to get everything right):
7651 If the client is directly connected local client then the
7652 `connection' argument must be set and `router' argument must be
7653 NULL to silc_idlist_add_client function. If the client is not
7654 directly connected client then the `router' argument must
7655 bet set and the `connection' argument must be NULL to the
7656 silc_idlist_add_client function.
7658 * The funtion silc_server_packet_send_local_channel actually did
7659 not check whether the client was locally connected or not. It
7660 does that now. Fixed a bug related to LEAVE command.
7662 * Fixed Remove Channel User payload parsing bug in server's
7663 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7665 * The server's silc_server_save_channel_key now checks also the
7666 global ID list for the channel as it might not be in the local
7667 list. Fixed a bug related to LEAVE command.
7669 * Is this the end of the [<unknown>] buglet that has been lurking
7670 around for a long time? A little for loop fix in server's
7671 silc_server_command_whois_parse that is used by both IDENTIFY
7672 and WHOIS command. At least, this was a clear bug and a cause
7673 of one type of [<unknown>] buglet.
7675 * WHOIS and IDENTIFY commands call the function
7676 silc_server_command_[whois/identify]_check function even if
7677 we are not router server.
7679 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7681 * Added --with-gmp configuration option. If set the GMP
7682 is always compiled in the SILC source tree. If not set then
7683 it is checked whether the system has the GMP3 installed. If
7684 it has then the GMP won't be compiled (the system's headers
7685 and library is used), if it doesn't have it then the GMP is
7686 compiled in the SILC source tree.
7688 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Changed RSA private exponent generation to what PKCS #1
7691 suggests. We try to find the smallest possible d by doing
7692 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7693 not security fix but optimization.
7695 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added new config entry [Identity] to fork the server and run
7698 it as specific user and group. A patch from Bostik.
7700 * Imported Dotconf configuration library into lib/dotconf.
7701 This will be used to create the SILC configuration files later.
7702 It will appear in the distsribution after this commit.
7704 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7706 * A big code auditing weekend happening. Auditing code for
7707 obvious mistakes, bugs and errors. Also, removing any code
7710 Removed files for being obsolete:
7712 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7713 inline in the file lib/silcutil/silcbuffer.h)
7715 o lib/silcutil/silcbufutil.c (the header has inline versions)
7717 Changed code to fix possible error conditions:
7719 o The buffer formatting routines now check that the destination
7720 buffer really has enough space to add the data. This applies for
7721 both buffer formatting and unformatting
7722 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7723 unformatting was changed to accomodate following rules:
7724 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7725 sent to the function while XXX_*STRING will not allocate or copy
7726 the data into the buffer. Instead it sets the pointer from the
7727 buffer into the pointer sent as argument (XXX_*STRING used to
7728 require that the pointer must be allocated already). This change
7729 makes this whole thing a bit more consistent and more optimized
7730 (note that the data returned in the unformatting with XXX_*STRING
7731 must not be freed now). The routines return now -1 on error.
7733 o Tried to find all code that use buffer_format and buffer_unformat
7734 and added return value checking to prevent formatting and
7735 especially unformatting errors and possible subsequent fatal
7738 o Changed ske->x and ske->KEY to mallocated pointers in
7739 lib/silcske/silcske.h. Fixed possible data and memory leak.
7741 o Added return value checking to all *_parse* functions. Fixed
7742 many memory leaks as well.
7744 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7745 so that buffer overflows would not happen. All code now also
7746 checks the return value as it can fail.
7748 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Added reconnection support to server if the normal server looses
7751 its connection to the router (for example if router is rebooted).
7752 The server performs normal reconnection strategy implemented
7753 to the server. Affected file silcd/server.c.
7755 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7757 * Added new packet type SILC_PACKET_SET_MODE that is used to
7758 distribute the information about changed modes (for clients,
7759 channels and clients channel modes) to all routers in the
7760 network. Updated the protocol specification accordingly.
7762 Added functions into silcd/packet_send.c and
7763 silcd/packet_receive.c: silc_server_send_set_mode,
7764 silc_server_set_mode.
7766 Added new files silcmode.[ch] into lib/silccore that implements
7767 the encoding and decoding of Set Mode Payload. Added new type
7768 SilcSetModePayload. Moved the definitions of different modes
7769 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7771 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Oops, a little mistake in server's connection authentication
7774 protocol. The protocol is not ended with FAILURE but with
7775 SUCCESS if the authentication is Ok. :) Affected file is
7778 * Implemented NICK_CHANGE notify handling in server in the file
7779 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7780 the local clients on the channel. After the changing nickname
7781 in router environment snhould work and the [<unknown>] nickname
7782 should appear no more.
7784 The silc_server_replace_id function that receives the Replace ID
7785 payload now sends the NICK_CHANGE notify type also in the file
7786 silcd/packet_receive.c
7788 * Changed WHOIS and IDENTIFY command to support the maximum amount
7789 of arguments defined in protocol specs (3328 arguments). This
7790 fixed a bug that caused problems when there were more than three
7793 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * Added extra parameter, command identifier, to the
7796 silc_client_send_command so that explicit command identifier
7799 Changed that ID list routines uses specific command identifier
7800 when sending WHOIS/IDENTIFY requests to the server so that they
7801 can be identified when the reply comes back.
7803 Affected files lib/silcclient/command.[ch],
7804 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7806 * Added `sender' argument to silc_server_packet_send_to_channel
7807 to indicaet the sender who originally sent the packet to us
7808 that we are now re-sending. Ignored if NULL. Affected file
7809 silcd/packet_send.[ch].
7811 * Added some server statistics support in silcd/server_internal.h
7812 SilcServerStatistics structure and around the server code. Also
7813 send some nice statistics information when client is connecting
7816 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Fixed channel ID decoding in server's JOIN command reply in
7819 silcd/command_reply.c
7821 * Fixed braodcasting of replace ID payload to not to send it if
7822 we are standalone server in silcd/packet_receive.c.
7824 * Fixed all channel message sending routines to not to send
7825 packets to clients that has router set, since they are routed
7826 separately in the same function earlier. Affects file
7827 silcd/packet_send.c and all channel packet sending functions.
7829 * In USERS reply, res_argv[i] are not allocated, the table
7830 is allocated. Thus changed that free the table, not its
7833 * In server's whois_check and identify_check if the client is
7834 locally connected do not send any WHOIS commands - they are not
7837 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7839 * Fixed some minor bugs in client when sending WHOIS command. The
7840 arguments was in wrong order.
7842 * Removed statis function add_to_channel from server in
7843 silcd/command.c that was previously used with the joining but
7846 * Tested USERS command in router environment successfully with two
7847 routers, two servers and two clients.
7849 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Reorganized the USERS command and command reply in client library
7852 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7853 When the command is given by user we register a pending command
7854 callback that will reprocess the command after the reply has been
7855 received from the server. When reprocessing the packet we then
7856 display the information. Thus, the USERS information is displayed
7857 now in the command callback instead of in the command reply
7858 callback. The processing of the command is same as previously
7859 when server has sent the command reply in the JOINing process.
7861 * Added to USERS command in silcd/command_reply.c to join the client,
7862 we didn't use to know about, to the channel after we've created
7863 a client entry for it. Also, for clienet we did know already still
7864 check whether it is on the channel or not and add it if not.
7866 * Removed silc_server_command_join_notify as the function and its
7869 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7871 * Changed the client's pending command handling to the same as the
7872 server's pending command handling. It is also now possible to
7873 execute command reply functions from other command reply
7874 function as the function callbacks for commands and command
7875 replies are one and same. The pending commands are not static
7876 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7877 in client connection context. Thus, pending commands are server
7878 connection specific as it is convenient.
7880 Changed the function silc_client_command_pending and
7881 silc_client_command_pending_del and added new function
7882 silc_client_command_pending_check. Removed the
7883 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7886 * Added cmd_ident, current command identifier, to the client
7887 connection context in lib/silcclient/client.h to keep track on
7888 command identifiers used in command sending. Client's command reply
7889 function handling now supports the mandatory command identifiers.
7891 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7892 funtions in client to fully support pending command callbacks.
7894 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7895 as one of the arguments to the application in the command reply
7898 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7899 before first releasing SILC but came back. Now it is removed again
7900 and should come back nomore. The FORWARDED flag was used only
7901 by the JOINing procedure by forwarding the command packet to router.
7902 Now, the JOINing procedure has been changed to more generic (due
7903 to various router environment issues) and FORWARDED is not needed
7904 anymore for anything. The protocol specification is yet to be
7907 Now, removed silc_server_packet_forward from server and the flag
7908 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7910 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7912 * Renamed NAMES command to USERS command. The NAMES was named that
7913 due to historical reasons. Now it is renamed. Also, rewrote
7914 parts of the USERS command. The nickname list is not sent anymore
7915 by the server. Only Client ID and mode lists are sent in the USERS
7916 command. Changed this also to the protocol specification.
7918 The client now resolves the names and stuff after it receives
7919 the USERS list from the server when joining to the channel.
7921 * WHOIS and IDENTIFY commands has been changed to support multiple
7922 Client ID's per command. One can now search for multiple users
7923 in the network by sending only one WHOIS or IDENTIFY command.
7924 Changed the code and the protocol specifications.
7926 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7927 uses silc_server_command_whois_parse to parse the request. */
7929 * If normal server, do not parse the WHOIS and IDENTIFY requests
7930 before sending it to the router. Saves some time.
7932 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7934 * Fixed JOIN command on client library. Wrong number of arguments
7935 used to crash the client.
7937 * Added silc_server_channel_has_global function to check whether
7938 channel has global users or not.
7940 * Added silc_server_channel_has_local function to check whether channel
7941 has locally connected clients on the channel.
7943 * The silc_server_remove_from_one_channel now checks whether the
7944 channel has global users or not after given client was removed from
7945 the channel. It also checks whether the channel has local clients
7946 on the channel anymore. If it does not have then the channel entry
7947 is removed as it is not needed anymore.
7949 * The silc_server_notify now checks on JOIN notify whether the joining
7950 client is one of locally connected or global. If it is global then
7951 the channel has now global users on the channel and that is marked
7952 to the channel entry. Also, it now saves the global client to
7953 global list who is joining and JOINs it to the channel. This is
7954 for normal server, that is.
7956 Changed silc_server_send_notify_on_channel,
7957 silc_server_packet_relay_to_channel and
7958 silc_server_packet_send_to_channel check if we are normal server
7959 and client has router set (ie. global client) do not send the
7960 message to that client, as it is already routed to our router.
7962 * Implemented LEAVE notify type handling in silc_server_notify
7965 * Tested LEAVE command in router environment successfully. Tested
7966 with two routers, two servers and two clients.
7970 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7972 * Implemented SIGNOFF notify type handling in silc_server_notify
7975 * silc_server_remove_id now removes the client entry from all channels
7976 it has joined and thusly sends SIGNOFF notify type.
7978 * Rewrote the NAMES list generation in server by removing two excess
7979 loops. The lists are created now inside one loop.
7981 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * silc_server_remove_channel_user checks now also global list
7984 for channel and client.
7986 * silc_server_new_channel_user checks now both local and global
7987 list for channel and client. Fixed a bug in client id decoding.
7988 Used to decode wrong buffer.
7990 * silc_server_channel_message checks now both local and global
7991 list for channel entry.
7993 * Tested channel joining (hence JOIN) in router environment
7994 successfully. Tested with two routers, two servers and two
7997 * Tested channel message sending in router environment successfully.
7999 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8001 * Added silc_server_save_channel_key into server.[ch] to save the
8002 received channel key in Channel Key payload processing. It is
8003 also used in JOIN command reply handling.
8005 Equivalent function silc_client_save_channel_key added into
8006 client.[ch] into client library.
8008 * Changed JOIN command reply to send information whether the channel
8009 was created or not (is existing already) and the channel key
8010 payload. Changed protocol specs accordingly.
8012 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8013 the request was sent by ID and not by nickname. Crashed on
8016 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8019 now correctly save the received data.
8021 * silc_server_free_sock_user_data now notifies routers in the
8022 network about entities leaving the network.
8024 At the same time implemented functions silc_server_remove_id
8025 and silc_server_send_remove_id to receive and send REMOVE_ID
8026 packets. The packet is used to notify routers in the network
8027 about leaving entities. The ID removed will become invalid in
8030 * Added function silc_idlist_del_server into server. Removes and
8031 free's server entry from ID list.
8033 * silc_server_private_message function now checks, if we are router,
8034 that the destination ID really is valid ID, naturally.
8036 * In router when NEW_ID packet is received (for new client) the
8037 hash of the Client ID is saved in the ID Cache but the
8038 client->nickname is set to NULL, instead of putting the hash
8041 IDENTIFY command now also checks that client->nickname must be
8042 valid. If it is not if will request the data from the server who
8043 owns the client. Added new function
8044 silc_server_command_identify_check.
8046 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8047 to set the command to already allocated Command Payload.
8049 * Tested private message sending in router environment with two
8050 routers, two servers and two clients. Fixed minor bugs and now
8053 * Fixed segfault from client's NAMES command. Used to crash if
8056 * Forwarded packets must not be routed even if it is not destined
8057 to the receiver. Changed server code comply with this.
8059 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8061 * Added `require_reverse_mapping' boolean value to ServerParams
8062 structure. If TRUE (not default) the server will require that
8063 the connecting host has fully qualified domain name.
8065 If the reverse mapping is not required and hostname could not be
8066 found the IP address is used as hostname.
8068 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8070 * Implemented version string checking to both client and server.
8071 The check is incomplete currently due to the abnormal version
8072 strings used in development version of SILC.
8074 * Changed all command functions in server to use the new
8077 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8079 * Changed char *data to unsigned char *data in ID Cache system to
8080 support binary data as ID Cache data. Changed code to support
8081 binary data in lib/silccore/idcache.c.
8083 * Renamed silc_server_packet_relay_command_reply to
8084 silc_server_command_reply as it is normal packet receiving
8085 function. Rewrote the function to accept command replys for
8086 servers and not only for clients.
8088 * Mark remote router always as registered server if we are connecting
8089 to it. Otherwise, commands sent by the router to us are ignored.
8091 * All ID List find routines now returns the ID Cache Entry pointer
8092 as well if requested.
8094 * WHOIS command works now in router environment, tested with two
8095 routers, two servers and two clients.
8097 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8098 in router environment (as it is almost equivalent to WHOIS) but
8099 hasn't been tested thoroughly. Added new functions:
8101 silc_server_command_identify_parse
8102 silc_server_command_identify_send_reply
8103 silc_server_command_identify_from_client
8104 silc_server_command_identify_from_server
8106 * Disabled route cache adding because adding two different ID's with
8107 same IP replaces the old cache entry thus giving wrong route.
8108 The entry->router->connection is always the fastest route anyway
8109 so route cache may not be needed. Of course, new routes maybe
8110 established after receiving the ID when the entry->router->connection
8111 might not be anymore the most optimal.
8113 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Add route cache for received ID for fast routing.
8117 * Added silc_server_packet_route to route received packet on router
8118 that is not destined to us.
8120 * Renamed silc_server_get_route to silc_server_route_get.
8122 * Added id_string and id_string_len fields into SilcServer to
8123 include encoded ServerID for fast comparing without excess
8124 encoding of the ID's.
8126 * Cleaned up WHOIS command on server side. Added following static
8129 silc_server_command_whois_parse
8130 silc_server_command_whois_check
8131 silc_server_command_whois_send_reply
8132 silc_server_command_whois_from_client
8133 silc_server_command_whois_from_server
8135 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8136 arguments in command replies. All command functions should be
8137 updated to use this macro.
8139 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8141 * Minor typo fixes on command reply handling on server.
8143 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8145 * Added silc_server_command_add_to_channel internal routine to add
8146 the client to the channel after router has created the channel and
8147 sent command reply to the server.
8149 * Added generic silc_server_send_command to send any command from
8152 * Use static buffer with ID rendering instead of duplicating data.
8154 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Fixed a channel user mode bug when joining to a channel server gave
8157 everybody channel founder rights, oops.
8159 * We mark ourselves as the router of the incoming server connection
8160 if we are router ourselves. This way we can check in some packet
8161 sending functions whether it is locally connected server. For
8162 incoming router connections we put NULL.
8164 * For router sending packets locally means now always sending the
8165 packet cell wide; to local clients and local servers. For normal
8166 server sending packet locally means sending it to only local
8169 * Fixed the JOIN command to really work in router environment. If the
8170 channel is created it is always created by the router. Router is
8171 also responsible of making the initial joining to the channel,
8172 sending JOIN notify to the sending server and distributing
8173 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8174 does not exist server doesn't do anything else but forward the
8175 command to the router which performs everything.
8177 * Added silc_server_send_channel_key function to send the Channel Key
8180 * Added silc_server_create_channel_key to create new channel key. The
8181 channel key is now re-generated everytime someone joins or leaves
8182 a channel, as protocol dictates. Note: channel->key_len is the
8185 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8188 packet_receive.[ch] to separate packet sending and receiving
8189 routines. The server.[ch] now includes everything else including
8190 actual packet processing (writing and reading data) and other
8193 Renamed silc_server_private_message_send_internal to
8194 silc_server_send_private_message. The routine is still though
8195 used only to relay private messages as server does not send
8196 private messages itself.
8198 Renamed silc_server_new_channel to silc_server_create_new_channel
8199 and added new function sicl_server_new_channel that handles the
8200 incoming New Channel packet. Added also new sending function
8201 silc_server_send_new_channel to send New Channel Payload.
8203 * Added new function silc_server_notify to process incoming notify
8204 packet to the server/router. Server may then relay the notify
8205 to clients if needed.
8207 * Added new function silc_server_new_channel_user to process incoming
8208 New Channel User packet. Router will redistribute the packet and
8209 send JOIN notify to its local clients and locally connected servers
8210 if needed. Normal server will send JOIN notify to its local client
8211 on same channel when received this packet. Added also corresponding
8212 sending function silc_server_send_new_channel_user to sent the
8215 * Added boolean route argument to send_notif_to_channel and
8216 packet_send_to_channel functions to attempt to route the packet
8217 if it is TRUE and send only locally if it is FALSE.
8219 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * silc_server_replace_id now broadcasts the received replace ID
8222 packet if it is not broadcast packet already. The router must
8223 broadcast to inform other routers about changed ID.
8225 * Added backpointer to server's router into SilcServer context in
8226 silcd/server_internal.h.
8228 * Fixed silc_server_packet_broadcast to send correct broadcast
8231 * The channel key is now distributed to the local client as soon
8232 as it is received from the router (in router environment) so that
8233 no other packet may be sent for the channel until client has
8236 * silc_server_remove_channel_user now broadcasts the received
8237 Remove Channel User packet if it is not broadcast packet already.
8238 The router must broadcast to inform other routers about removed
8241 * Added users field into SilcPacketContext that is a reference count
8242 of the context. One can increase the reference count by calling
8243 silc_packet_context_dup which is now changed to just increase the
8244 reference count instead of duplicating the data. The reference
8245 count is decresed by calling silc_packet_context_free that will
8246 free the data after the reference count hits zero.
8248 For now on the packet context and everything allocated into it
8249 (including the raw packet from network) must be freed by calling
8250 the new silc_packet_context_free function. Added also new function
8251 silc_packet_context_alloc that must be used now to allocate the
8252 context. This also means that if a routine is asynchronous from
8253 silc_[client/server]_packet_parse_type the packet context must
8254 be duplicated by calling silc_packet_context_dup. Otherwise it
8255 gets free'd after silc_[client/server]_packet_parse_type returns.
8256 Also, one must remember that if packet is duplicated then its
8257 reference count must be decresed by calling the free function as
8258 many times as it was duplicated.
8260 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8261 from both client and server.
8263 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8265 * Made joining to a channel working in router environment.
8267 * Cleaned up JOIN command on server side and create function
8268 silc_server_command_join_channel internal routine to make the
8271 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Changed silc_command_pending list to SilcDList. Also, added
8274 `ident' field to SilcServerCommandPending structure to identify
8275 the reply and to call correct callback.
8277 Added silc_server_command_pending_check function to replace the
8278 corresnponding macro. The silc_command_pending list is not
8281 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8282 to set identifier to previously allocated Command Payload. It
8283 is used to set identifier for command when resending Command
8286 * Added silc_command_payload_encode_payload to encode Command
8287 Payload buffer from SilcCommandPayload structure.
8289 * Added silc_argument_payload_encode_payload to encode Argument
8290 payload buffer from SilcArgumentPayload structure.
8292 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8294 * Changed WHOIS command to support router connection on server side.
8295 The whois request is always sent to router unless the server is
8296 standalone server. After server has received the reply from the
8297 router will it send the reply to the client.
8299 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8300 broadcast received broadcast packet. The function is used only
8301 by router. The broadcast packet is always sent to the router's
8304 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8305 render given ID to printable string, for log files for example.
8307 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8309 * Made basic router to router connections working. At least they
8310 can now connect to each other but nothing really works the way
8311 they are supposed - yet.
8313 * Added new initiator token to RouterConnection configuration
8314 file in silcd/serverconfig.[ch]. It is used to tell whether we
8315 are the initiator to the remote router or whether we'll expect
8316 the other end to connect.
8318 * Moved registering of listener task to silc_server_init, hence
8319 the server starts listenning as soon as it is run, even if it
8320 does not have connections to other routers. Let's see how well
8323 * Changed default connection retry timeouts for more suitable in
8326 * Removed cipher and such arguments from silc_idlist_add_client
8327 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8328 Added new function silc_idlist_add_data to add the keys and stuff
8331 * Added SilcIDListData structure and added it to SilcClientEntry
8332 and SilcServerEntry as their first field in the structure. This
8333 way we can explicitly cast the ID entries to the SilcIDListData
8334 structure and get common data for the entries. In past, we had
8335 to first check what type of connection it is and then cast it to
8336 correct ID entry type. Now, we can directly cast the opaque
8337 pointer to the SilcIDListData (no matter what ID entry it actually
8338 is) and get the data needed.
8340 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8342 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8343 in some circumstances even if threre were timeout tasks, though not
8344 IO tasks, but tasks anyway. Now fixed.
8346 * Defined SilcServerConnection structure to hold connection specific
8347 stuff about directly connected servers and routers. The definition
8348 is currently in silcd/server_internal.h. I thought about having
8349 a bit more important role fro this struct but for now it is used
8350 only when connecting to other server (or router actually).
8352 * Added connecting retry support in server when connecting to
8353 router(s). The retry feature implement exponential backoff
8354 algorithm. Also, added SilcServerParams structure to hold default
8355 parameters for server. For now, it include these retry settings
8356 and are hard coded. After server is moded to be as Silc Server
8357 Library this structure will be more important.
8359 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Changed client librarys channel->clients table to SilcList and
8362 changed code accordingly.
8364 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * Changed client's channel table to SilcList and changed code
8367 accordingly. Also changed SilcChannelClientEntry to include back-
8368 pointer to the channel so that client entry can use that structure
8369 as list as well and we have fast cross-reference to the channel.
8370 This change dramatically decreased the complexity of channel
8371 handling with client entry and vice versa (removed one extra
8372 loop when searching for channel entry from many functions).
8374 * Changed server->sim from table to SilcDList and changed code
8377 * NAMES command can now be used from user interface. It will show
8378 the user list on the channel, neatly.
8380 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8381 Code now saves realname of the user if it becomes available.
8383 * Renamed configure.in to configure.in.pre and made ./prepare
8384 script to automatically add correct version string to
8385 configure.in which it creates from configure.in.pre.
8387 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8389 * NAMES command reply now shows users mode with the nickname when
8392 * Moved silc_client_ch[u]mode[_char] functions from
8393 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8394 place sucks, they are utility functions and should be in some
8397 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8399 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8402 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * Added TRQ (efficient deque and list library) into lib/trq. This is
8407 a very good list library that is currently used in the SILC. Defined
8408 SilcList API over the library because I didn't like the API very
8409 much. See lib/trq/silclist.h for the API and examples of how to
8410 use the API. Fixed various places in the code to use the new
8411 SilcList API. The SilcList is meant for lists that has a structure
8412 already defined as a list. It is not suitable to add just some
8413 context to the list (in TRQ, the context is the list actually).
8415 So, I defined SilcDList that can be used for the purpose where
8416 predefined list structure does not exit. This can be used as
8417 such list. Now some context just can be added to the SilcDList.
8418 Currently this list is not used in the SILC just yet, though there
8419 are a lot places where this can replace dynamically allocated
8420 tables and I will fix these places, later, to use SilcDList.
8421 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8422 and use TRQ internally).
8424 Also fixed some annoying warning messages that the original TRQ
8425 code generated. Also minor changes to TRQ's Makefile.in.
8427 * Added support for querying by Client ID to both WHOIS and
8428 IDENTIFY commands into server, as required by the protocol.
8430 * Removed method function pointers from SilcBuffer structure. They
8431 weren't used to anything and just increased the context size for
8432 no good reason. This change also made silc_buffer_alloc and
8433 silc_buffer_free functions inline functions.
8435 * Disabled command flooding detection support until it's fixed so
8436 that it accepts commands in but does not execute them more than once
8439 * Added silc_net_localhost(), to return local hostname, into
8440 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8441 that must be initialized before calling silc_client_init.
8443 * Added new function: silc_server_send_notify_on_channels to send
8444 notify messages to all channels client has joined. It is assured
8445 that the message is sent only once per client.
8447 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8448 lib/silcutil/silcutil.[ch] as silc_format function. The new
8449 function is generic and is used by server as well, not only by
8450 the logging routines.
8452 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8453 the provided version string was not acceptable. Added new function:
8454 silc_ske_check_version into lib/silcske/silcske.h. The function
8455 must be implemented by the application (client or server) and it
8456 does not reside in the SKE library. The function checks the version
8457 string remote end sent.
8459 * Added back pointers (to opaque context and to SilcSocketConnection)
8460 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8462 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8463 duplicate packet context structure.
8465 * Changed `notify' client operation to send same arguments as client
8466 receives from server except for ID's. ID's are mapped to correct
8467 ID entry and that is returned. Also, if channel entry is not sent
8468 by server but the notify is for channel the channel entry is sent
8469 to application (otherwise application doesn't know that it is for
8470 channel (library gets it from packet's Destination ID)).
8472 * Added silc_client_remove_from_channels into client library to
8473 remove a client from all channels it has joined to. Used when
8474 received SIGNOFF notify from server. Added also new function
8475 silc_client_replace_from_channels to replace old ID entry with
8476 new ID entry on all channels. Used when received NICK_CHANGE
8479 * Fixed ID Cache list handling in silc_idlist_get_client in
8480 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8481 to get (or query) client by ID.
8483 * Updated TODO list.
8485 * Added connection authentication status message defined by the
8486 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8487 support for these into the code in client and server side.
8489 * Added generic function silc_client_send_command to send any command
8490 with variable argument list. Application should use this function
8491 to send commands if the command functions provided by the library
8492 does not suite for the application's user interface needs.
8494 * Added new `failure' client operation. Application is notified about
8495 received failure packet if client is executing a protocol. In this
8496 case the protocol's execution has failed.
8498 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8499 is required by the protocol.
8501 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8502 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8505 * Added status flag to SilcSKE object to indicate realtime status
8506 of the SKE protocol.
8508 * Application receives now exactly same command reply arguments as
8509 the library receives from server. However, if ID is received the
8510 corresponding ID entry is returned to the application (eg. Client
8511 ID is mapped to correct SilcClientEntry entry and that is returned).
8512 Changed command_reply client operation due to this change.
8514 * Changed all ID's in commands and in command replys as ID Payloads.
8515 Change affected both client and server side codes.
8517 All ID's sent in SILC network (with execption of ID's in SILC
8518 Packet header) are sent in ID Payload to support variable length
8521 * Server now notifies nick changes and notifies all clients on
8522 the channels about the new nickname (about the new Client ID,
8525 * Implemented CMODE command to change channel modes. Supports all
8526 channel modes defined by the protocol specs except ban and invite
8527 lists. (Also, private channel key mode is supported but support for
8528 setting private channel key in client is missing, thus, this mode
8529 has no effect on client side (except that server requires that the
8530 client uses private channel key and normal channel traffic does not
8533 Also, invite mode works per se, but INVITE command does not work
8534 yet correctly, so you can set channel as invite only channel but
8535 inviting clients to the channel does not work (it is yet to be
8536 thought what's the best way to do it).
8538 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8539 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8540 Implemented CUMODE command to change user's mode on the channel.
8541 Supports all modes defined by the protocol specs.
8543 * Added NAMES command reply to return users modes on the channel.
8545 * Removed unnecessary and slow ciphers from lib/silccrypt.
8547 * Set SO_KEEPALIVE option to connection sockets by default.
8549 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8551 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8552 redefined the Notify Payload into protocol specs.
8554 * Added silc_id_payload_parse_id to get ID directly from raw
8557 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8559 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8560 accept searching by Client ID as well.
8562 * Added support for LEAVE and SIGNOFF notify types in client library.
8564 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8565 to parse ID Payload from raw data.
8567 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8569 * Added flags parameter into silc_ske_assemble_security_properties
8570 function in lib/silcske/silcske.[ch].
8572 * Changed notify client operation to fit better for notify messages
8573 sent by server. The notify payload received from server is now
8574 passed to the application (after parsing it to SilcNotifyPayload).
8575 It is application's responsibility to retrieve the arguments
8576 from the payload and show the message the way it wants. The message
8577 sent by server is implementation specific.
8579 * Changed public keys to comply with the protocol specification.
8580 Old public keys are not supported anymore and are not compatible.
8582 * Removed nickname from Channel Payload as the latest draft removed
8583 it. The client must resolve the nickname from the NAMES command
8584 reply received when it joined the channel.
8586 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8588 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8590 * Fixed some errors in protocol specification drafts.
8592 * Created lib/silccore/silcnotify.c to implement Notify Payload
8593 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8594 generic payloads described by protocol specifications. The file
8595 includes implementations for ID Payload and Argument Payload.
8597 * Changed Command Payload implementation to use the new Argument
8598 Payload. Changed command_xxxx_payload to command_payload_xxxx
8599 to comply with SILC coding conventions.
8601 * Added suppport for Argument Payload handling in Notify Payload
8602 implementation as protocol requires it. Added the new support
8603 into server and client lib as well.
8605 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Added support for multiple nicknames on same channel. [n] is
8608 added locally to the nickname if there are more than one same
8609 nicknames on the channel.
8611 * Server now sends all nicknames that matched WHOIS request.
8612 Client also shows the list received from server.
8614 * Added TOPIC command to client side. User can now set and show
8615 current topic on channel.
8617 * Added MOTD command to client and server. Also, server sends the
8618 motd when client connects to the server.
8620 * Changed version strings to comply ISO 8601.
8622 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8624 * Fixed protocol error handling in client library. It should now
8625 cope even if the SKE fails for some reason.
8627 * Made new protocol specification drafts for submitting to IETF.
8629 * Implemented TOPIC command to server in silcd/command.c.
8631 * Added two new notify types into lib/silccore/silcnotify.h:
8632 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8633 notify nickname change and topic setting/change on a channel.
8635 * API change of command_reply operation in client library. The
8636 application gets now the status type received from server as well.
8638 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8640 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8642 * Cras fixed and optimized the packet handling even further and
8643 it should work now. Minor change to the prototype of function
8644 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8646 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8648 * Added new function into lib/silcutil/silcschedule.[ch]:
8649 silc_schedule_with_fd to select() a specified fd. The function
8650 returns after timeout expires or data arrives or goes. The
8651 function is used by packet routines to wait that all data is
8652 received from network.
8654 * Fixed data reading from network in lib/silccore/silcpacket.c.
8655 The code now assures that all data is read from the fd and then
8656 continues packet processing. This was a bug fix since the code
8657 used to drop some data in some circumstances.
8659 * Added new function into lib/silcclient/client.[ch]:
8660 silc_client_start_key_exchange to start key exchange after
8661 connection has been established to server. The code internally
8662 now uses this funtion but its main purpose was to provide it
8663 for applications that perform their own connecting. After
8664 application has created a connection it merely calls this
8665 function to start the key exchange between client and server.
8666 The library takes care of everything else after that.
8668 Updated also lib/silcclient/README to explain the usage of
8671 * Do not send to application information that connection has
8672 been established. Application gets notified it by connect
8675 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8677 * Applied cras's patch to add silc_schedule_one function. The
8678 function runs scheduler once and returns.
8680 * Fixed the scheduler after cras messed it up. The timeout
8681 handling works now as it's supposed to work.
8683 * Added into lib/silccore/ silcnotify.h to include notify
8684 message types support. Changed silc_server_send_notify*
8685 functions, in server.[ch], to support those new notify types.
8686 Added the support for the notify types into client library,
8687 as well. Added new notify client operation into ops.h in
8690 * Changed silc_server_packet_send_to_channel to send normal
8691 packets instead of just channel message packets. The function
8692 is now used to send the notify packets to channels. It is not
8693 used to send channel message packets anymore, as server never
8696 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8697 va_arg()s as it seems to require it nowadays. I guess, if SILC
8698 is compiled with older va_arg() the new code should work anyway.
8700 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8702 * Splitted core library. Core library (lib/silccore) includes
8703 now only SILC protocol specific core (and common) components.
8704 Created new utility library (lib/silcutil) that includes more
8705 generic purpose stuff. The stuff for util library was taken
8706 from the old core library. This was minor and easy split.
8708 * Created SILC Client Library (lib/silcclient) that includes
8709 implementation of the SILC client without user interface. This
8710 was major move from silc/ directory. The code has been changed
8711 so that it is transparent towards the user interface. The
8712 silc/ directory includes now the same user interface as before
8713 and it uses the new client library. Read lib/silcclient/README.
8714 Basicly, the client library performs everything else related
8715 to SILC except user interface handling. Also, configuration
8716 files are considered to be part of user interface and library
8717 does not handle them.
8719 This change also changed a lot of structures, function naming etc.
8720 Most important change was that SilcClientWindow object was
8721 renamed to SilcClientConnection in the client library. Created
8722 also new file lib/silcclient/ops.h. Also added new files
8723 silc/local_command.[ch] and silc/client_ops.[ch].
8725 All these changes were made to make it easier for user interface
8726 designers to create what ever user interface for the SILC client
8729 It is also expected that the server will be moved to lib
8730 directory as well and SILC Server Library will be created;
8731 sometimes in the future.
8733 * Removed Local commands from lib/silccore/silccommand.h as
8734 they are application specific and new client library does not
8735 handle any of those anymore.
8737 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8738 old client implementation in silc/.
8740 * Added support for callback functions in SILC_LOG_* macros.
8741 Application can now set its own callbacks that will be called
8742 instead of using the default functions that will always print
8743 the debug messages to stderr (or stdout). Also, debugging can
8744 now be disabled by setting silc_debug to FALSE and re-enabled by
8745 setting it to TRUE. Note, that logging will still work even
8746 if debugging is disabled.
8748 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8749 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8750 silc_log_reset_debug_callbacks.
8752 * To enable debugging in silc client one must give now -d
8753 option on command line.
8755 * Changed silc_schedule_init to automatically allocate task queues
8756 if they are not allocated before calling it.
8758 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8760 * Added GMP 3.1 into math library.
8762 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8764 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8765 a channel in SILC network. The packet is used by servers and
8766 routers to notify other routers that user has left a channel.
8767 This little feature was missing until now. Added the feature
8768 to protocol specification as well.
8770 Added functions: silc_server_send_remove_channel_user and
8771 silc_server_remove_channel_user into server.[ch].
8773 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8774 lib/silccore/silcpacket.h. However, they are not implemented
8777 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8779 * Fixed joining to a channel and sending channel messages
8780 between server and router. The channel message sending should
8781 now work inside a cell.
8783 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8785 * Fixed the private message sending between server and router.
8786 The private message sending should now work inside a cell.
8788 * Added silc_server_replace_id into server.[ch] to replace
8789 existing ID in the SILC network.
8791 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8792 and silc_idlist_replace_server_id into idlist.[ch] in server.
8794 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8796 * Fixed the server to server connections. Server can again now
8797 connect to router. Router to router connections probably does
8800 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8802 * Added dynamic protocol registering support. Now protocols can
8803 registered and unregistered on the fly. Patch by cras.
8805 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8807 * Added lib/contrib directory to hold routines that some platforms
8808 don't have but are needed by SILC.
8810 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8811 into lin/contrib to provide getopt() and getopt_long() for
8812 those who don't have it.
8814 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8816 * Added AWAY command to client. When away message is set and
8817 client receives a private message packet the client automatically
8818 replies to the sender with the away message.
8820 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8821 bug seemed to be the cause of recent problems when compiling
8824 * Added version detection support to SKE protocol specification
8825 and added the new changes to the SKE implementation as well.
8826 There were other minor changes in the SKE protocol as well.
8828 Many changes in lib/silcske/silcske.[ch] and in
8829 lib/silcske/payload.[ch].
8831 * Added ^U functionality, clear input line. Patch from cras.
8833 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8835 * Mainly small bugfixes on core library. Fixed some debugging
8836 logging and buffer overflow in silclog.c.
8838 * Updated config.sub and config.guess on the distribution tree.
8840 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8842 * Added command lagging support in server. Client may execute
8843 commands now only once in two seconds.
8845 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8847 * Optimized packet reception. MAC computation and checking is now
8848 also more optimized. A lot previously duplicated code is now
8849 used as generic by both client and server.
8851 * Fixed key pair generation in clientutil.c
8853 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8855 * Added into lib/silccore/silcbufutil.[ch] new function;
8856 silc_buffer_realloc.
8858 * Moved generic packet sending/encryption functions to
8859 lib/silccore/silcpacket.[ch] from client and server. Some
8860 rewriting of the functions.
8862 * Moved all generic packet reception/decryption functions to
8863 lib/silccore/silcpacket.[ch] from client and server. The
8864 packet processing is now much cleaner in both client and server.
8865 These were major changes in both client and server.
8867 * Created many common functions in server to do packet sending.
8868 Previously code were duplicated a lot, this has been removed
8871 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8873 * Rewrote major parts of the ID cache system. Don't know
8874 whether it is better now or not but at least the API is more
8877 * Major rewrite on ID cache stuff on client because of the ID
8878 cache API changes. Added idlist.c to client.
8880 * Also major rewrite on ID cache stuff on server as well.
8881 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8882 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8883 in hand, instead they are all put into the ID cache system now.
8884 All server_idlist_* routines uses ID cache now instead of
8885 traversing its own lists (those lists does not exist anymore).
8886 SilcIDList though still exists. Also, SilcXXXEntry's are
8889 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8891 * Finally made the SKE implementation compliant to the protocol
8892 specification. All mp integers are now binary encoded as
8893 opposed being HEX encoded.
8895 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8898 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8899 functions: silc_[encode/decode]_pem. Also added function
8900 silc_encode_pem_file to PEM encode with newlines ('\n') for
8903 * SILC public keys are now encoded either PEM or binary. Same
8904 option is for private keys as well. By default private keys
8905 are binary encoded and public keys PEM encoded. Silly HEX
8906 encoding were removed.
8908 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8909 function to create fingerprints.
8911 * Fixed a bug in SHA1; does not change the original data anymore.
8913 * Partly implemented INFO command on client and server side.
8914 Fixed CLEAR command. Changes to SERVER command; show current
8915 server(s) when giving command without arguments. Added
8916 VERSION command to client.
8918 * Added check to server that unregistered connections cannot
8919 execute commands (unless it is specificly allowed).
8921 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8923 * Fixed screen refresh.
8925 * Fixed channel joining bug from client. On some circumstances
8926 client tried to join to a channel it had already joined.
8928 * Added public key verification process into client's protocol.c.
8929 The client now verifies the public key from user and saves
8930 it into ~./silc/serverkeys/ directory.
8932 Added into: clientutil.[ch]: silc_client_verify_server_key.
8934 * Changed SKE protocol's silc_ske_initiator_finish function
8935 to accept callback function that verifies the received public
8936 key. Removed old silc_ske_verify_public_key function.
8938 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8940 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8941 silc_pkcs_private_key[_data]_set.
8943 * Made the password and public authentication more cleaner in
8944 server's protocol.c.
8946 * Removed historic and obsolete protocol `channel_auth' from
8947 both client and server.
8949 * Removed wrong way of sending command status messages from
8950 server to client in server's command.c. The old way violated
8951 protocol specification.
8953 Changes to silccore/silccommand.[ch]: removed
8954 silc_command_encode_status_payload -> not needed anymore,
8955 changed silc_command_encode_payload_va to accept extra
8956 argument on variable argument list. The argument type must
8957 now be provided to the function. Also, added new function:
8958 silc_command_encode_reply_payload_va which is same as
8959 normal command_encode_payload_va except command status type
8960 is provided as extra argument.
8962 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8964 * Added ~./silc directory handling. The directory includes the
8965 public and private keys for the client.
8967 Added silc_client_check_silc_dir, silc_client_create_identifier
8968 and silc_client_load_keys.
8970 * Implemented SILC protocol compliant public key. Added public
8971 and private key saving to and loading from files.
8973 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8974 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8975 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8976 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8977 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8979 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8980 silc_pkcs_load_[public/private]_key.
8982 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8984 * Added silc_server_get_route (route.[ch]) to get connection
8985 data for the fastest route for given ID.
8987 * Implemented INVITE command on client and server. The command
8988 were re-defined in the SILC Protocol Specification and the
8989 implementation now complies with the specification.
8991 * Implemented PING command on client and server.
8993 * Implemented NAMES command on client and server. The server side
8994 supports currently only normal server not router server yet.
8995 Some changes to NAMES definition in SILC protocol specification.
8997 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8999 * Implemented LEAVE command on client and server.
9001 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9002 again. This change was made to the protocol as well. Server
9003 should not violate the protocol specification anymore.
9005 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9007 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9008 was tested. SOCKS4 was not but should work anyway.
