1 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Return NO_SUCH_CHANNEL error in USERS for channel that is
4 secret or private, otherwise it's possible to find out
5 whether a secret channel exists or not. Affected file
8 * If CMODE change fails during the mode setting, assure that
9 the old mode mask is set for the channel back. Affected
12 * Fixed passphrase saving on +a channel on normal server
13 after successful JOIN command. Affected file silcd/command.c.
15 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * Remove server/router operator privileges in DETACH command,
18 since it's possible to resume to server where these
19 privileges would not be allowed for the client. Affected
22 * Do not set to wait for backup in rehash of the server.
23 Affected file silcd/server.c.
25 * Do not check listener sockets when counting how many
26 socket connections we have. Affected file is
29 * Do not announce disconnected clients that are remaining
30 in history (for WHOWAS). This is because SIGNOFF notify
31 for these has been sent earlier already. Affected file
34 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
36 * Buffer overflow with CUMODE command's mode->mode character
37 conversion. Reported by Ville Räsänen. Affected file
38 lib/silcutil/silcutil.c.
40 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
42 * Allow heartbeat packets to go disabled connections anyway.
43 Affected files silcd/server.c and silcd/packet_send.c.
45 * Do not broadcast New Channel packets with List flag set
46 in the packet to backup routers. The router must check
47 for the correctness of the packets before sending them.
48 It is possible that router will have enforce Channel ID
49 change and this would cause desync in the backup router.
50 Affected file silcd/packet_receive.c.
52 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
53 are handled in list parsing. They are not list packets
54 anymore. Affected file silcd/packet_receive.c.
56 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
58 * Stop waiting for backup router through the timeout, not
59 directly after backup router has arrived. Affected file
62 * Do not re-create channel keys and send them when removing
63 clients in server shutdown. Affected files are
64 silcd/server_internal.h and silcd/server_util.c.
66 * Notify distribution to backup routers was missing from
67 the silc_server_send_notify_dest function which caused
68 desyncing problems with backup router. Affected file is
71 * The client's channel removing was working wrong on
72 backup router. It assumed that it doesn't know global
73 information but backup router does know. For this reason
74 it could remove channel when it wasn't supposed to do that.
75 Affected file silcd/server.c and silcd/server_util.c.
77 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Stop for a couple seconds after badkup router has become
80 primary router. Affected file silcd/server.c.
82 * Added silc_server_remove_servers_by_server, which is used
83 to remove servers originated from some other server. Also
84 clients of those servers can be removed too. Affected file
85 silcd/server_util.[ch].
87 * When removing clients after a server has signed of remove
88 also all servers behind that server (unless they are known
89 to be available locally), and send SERVER_SIGNOFF for each
90 of the server separately. Also the signed off clients are
91 sent now separately per signed off server. The affected files
92 are silcd/server.c and silcd/server_util.[ch].
94 * All servers added with silc_idlist_add_server must always
95 have both "router" and "connection" pointers set. Otherwise,
96 bad server entries may be left around in the cache.
97 Affected file silcd/command_reply.c.
99 * Do not create the channel key in NEW_CHANNEL packet
100 processing if the channel is empty. Affected file
101 silcd/packet_receive.c.
103 * Completed backup router support for standalone routers.
104 Supports also servers in the cell that do not use the backup
107 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Fixed a bug in silc_string_regexify which did not add '^'
110 at the start of each string, and thus the matching was
111 not explicit. For example ban list iikone@*!*@* would
112 match also "priikone", which is wrong, it would have to be
113 *iikone@*!*@* to match also "priikone". Affected
114 file lib/silcutil/unix/silcunixutil.c.
116 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
118 * Enable all local server connections before updating client
119 caches when we've become backup router. Otherwise, signoff
120 packets may not reach the clients. Affected files are
121 silcd/server.c and silcd/server_util.[ch].
123 * Fixed a bug in version string parsing which could crash
124 the program with specially formatted version string.
125 Bug reported and patch provided by Ville Räsänen. Affected
126 file lib/silcutil/silcutil.c.
128 * Handle the disconnection immediately when DISCONNECT
129 packet is received in server. Affected file silcd/server.c.
131 * Primary router now waits a short time (10 seconds) for
132 backup router connection before accepting any other
133 connection (except local). Affected file silcd/server.c,
136 * Fixed a crash in client libary in NICK_CHANGE notify when
137 NICK_CHANGE arrived for client entry we are resolving
138 currently. Affected file lib/silcclient/client_notify.c.
140 * Call the sconn->callback completion even if error had
141 occurred. Start reconnecting always if connection to
142 primary router fails during backup router protocol.
143 Affected files silcd/server.c and server_backup.c.
145 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Added functions silc_server_send_opers and
148 silc_server_send_opers_notify to send packets stricly
149 to operators. Added macro SILC_SERVER_SEND_OPERS macro
150 to send variable argument notify to operators.
151 Affected files silcd/packet_send.[ch] and silcd/server.h.
153 * Removed UMODE rights checking with UMODE_CHANGE notify.
154 Affected file silcd/packet_receive.c.
156 * Server/router operator now receives notify when network
157 switches to backup router and when it resumes the use of
158 primary router. Affected file silcd/server.c and
159 silcd/server_backup.c.
161 * Fixed the updating of client information after backup
162 resuming protocol is over; update all except local clients
163 to the new primary router. The affected file is
166 * Added support for closing active connections in rehash
167 that were unconfigured by the user. Supports currently
168 closing server and router connections. Affected file
171 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
173 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
176 is NULL since seems that on some platforms NULL is allowed
177 and on some it's not. Fallback encoding is used instead.
178 Affected file lib/silcutil/silcstrutil.c.
180 * Fixed statistics updating for incoming server connection
181 which could cause problems when re-connecting. Affected
184 * Preliminary backup router support for standalone router
185 added. Affected files in silcd/.
187 * Mark server connections in backup router disabled before
188 and after backup protocol. Affected file is
189 silcd/server_backup.c.
191 * Added support for reconnecting to remote server connection
192 even if the protocol fails, and if the configuration wants
193 us to keep trying to connect anyway.
195 Server connection is not allowed to backup router if
196 backup router does not have connection to primary router yet.
198 Affected file is silcd/server.c.
200 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
202 * Added silc_client_udpate_server function to update changed
203 server info. Affected file lib/silcclient/idlist.[ch].
205 * Added check for server entries that are being resolved when
206 notify is received. If being resolved, handle the received
207 notify only after it's resolved so that all notifys are
208 handled in same order as received from the server.
210 Added similar resolver check to channel entries. Every
211 notify that cause resolving of any information that affects
212 channel entry marks the channel entry in waiting state.
213 After whatever resolving is over the waiters are signalled
214 and only then the notifys are handled in the same order
215 as delivered from the server.
217 Affected files are lib/silcclient/idlist.[ch], and
220 * Fixed KILLED notify handling in normal server. Affected
221 file silcd/packet_receive.c.
223 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
224 is locally connected, or was locally connected (but may
225 be detached and connection is not active). Added also
226 SILC_IS_LOCAL for checking this status. Affected files
227 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
228 silcd/server.c and silcd/server_internal.h.
230 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
232 * Don't send or handle TOPIC_SET if topic is already set and
233 is same as being set. Affected files silcd/command.c and
234 silcd/packet_receive.c.
236 * Fixed CMODE change rights checking to work correctly when
237 removing modes by operator. Affected file is
240 * Fixed some handling with New Channel packet in router and
241 fixed some CMODE_CHANGE notify handling in server and router.
242 Affected file is silcd/packet_receive.c.
244 * Changed "disconnect" client operation to include the
245 reason of the disconnection and optional disconnection
246 message. Affected file lib/silcclient/silcclient.h.
248 * Made the compilation of lib/contrib/ stuff conditional.
249 Affected files configure.in.pre, lib/contrib/Makefile.am.
251 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
253 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
254 to the sender of the notify too, to avoid situation where two
255 notifys are in the network at the same time going to oppsite
256 directions. Affected file silcd/packet_receice.c.
258 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
260 * Delete the client from channel even if the cilent->id is
261 NULL. It was possible that client was deleted without
262 removing from channels (theoretically at least). Affected
263 file silcd/server.c and silcd/server_util.c.
265 * Free the client data too when resuming is not successful.
266 Affected file silcd/packet_receive.c.
268 * Merged some code from c0ffee's silc-plugin. Affected files
269 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
271 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
272 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
273 to the primary router connection, the other one returns
274 TRUE if packet must be broadcasted to network.
276 * All notifys that are destined to primary router (to network)
277 are now automatically sent to backup routers even if the
278 router is standalone (and has backup router). Affected files
281 * Added --without-irssi and --without-silcd configuration
282 options for disabling the compilation of these applications.
283 Affected file configure.in.pre and prepare.
285 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
287 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
288 UTF-8 encoding and decoding. Added also new encodings
289 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
291 Added also SILC_STRING_LANGUAGE which is language and charset
292 specific encoder and decoer for those platforms that support
293 iconv(). It can convert the UTF-8 to and from the locale
294 specific character set.
296 Affected file lib/silcutil/silcstrutil.[ch].
298 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
300 * Added function silc_get_command_name to the file
301 lib/silcutil/silcutil.[ch].
303 * Improved the server debug output a bit. Affected files are
306 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
308 * Save the channel passphrase when received succesful JOIN
309 command reply from router, on normal server. Otherwise
310 joinig +a channels from normal server is not possible.
311 Affected file silcd/command.c.
313 * Fixed a bug in TOPIC_SET notify handling. The notifier
314 may be other than client too, like server or channel.
315 It expected it to always be only client and ignored the
316 notify. Affected file silcd/packet_recieve.c.
318 * Removed some (unnecessary) debug printing from
319 lib/silccore/silcid.c and lib/silccore/silcargument.c.
321 * Do not force CMODE_CHANGE when server is announcing new
324 Router announces stuff only after server reannounces channel
325 after CHANNEL_CHANGE notify.
327 These fixes optimizes the announcing procedure, and perhaps
328 fixes some problems too. Affected file silcd/packet_receive.c.
330 * Fixed SERVER_SIGNOFF sending to local clients. It was
331 totally broken and sent the notify to all local clients,
332 instead of only to those that was on same channel as the
333 signing off clients. Affected file silcd/server_util.c.
335 * Added -D option to server. It can be used to give debug
336 level. The levels are from 0 - 99, and are predefined for
337 smooth server debugging. (see silcd.c for the predefined
338 levels). Affected file silcd/server.c.
340 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
342 * Fixed a bug in Irssi SILC client to close the connection
343 properly when disconnecting from server. Affected file
344 irssi/src/silc/core/client_ops.c.
346 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
348 * When authenticating as founder during JOIN command, check
349 that the one authenticating becomes the only founder on the
350 channel. Affected file silcd/command.c.
352 * Better checking for founder mode setting when CUMODE_CHANGE
353 notify is received. Affected file silcd/packet_receive.c.
355 * Close all connections when shutting down the server by sending
356 DISCONNECT packet. Close all listeners too when shutting
357 down the server. Affected file silcd/server.c.
359 * Handle DISCONNECT packet correctly in client library by
360 calling the "disconnect" client operation. Affected file
361 lib/silcclient/client.c.
363 * Handle local errors correctly during resuming. Affected
364 file lib/silcclient/client.c.
366 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
368 * The log file is not dupped internally anymore in
369 lib/silcutil/silclog.c. Fixed memory leaks too.
371 * The scheduler now dispatches all pending timeout tasks
372 when it is uninitialized with silc_schedule_uninit.
373 Affected file lib/silcutil/silcschedule.c.
375 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Added --enable-stack-trace option to configure. Added
378 memory allocation stack trace support. Added files
379 lib/silcutil/stacktrace.[ch]. Affected files are
380 lib/silcutil/silcmemory.[ch].
382 * Fixed memory leaks from libraries and server. Affected
383 files around the tree.
385 * Reverted back a fix made to CUMODE which broke it.
386 Affected file silcd/command.c.
388 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
391 core library, and implemented it. All textual messages SHOULD
392 use this flag and the message MUST be UTF-8 encoded.
393 All text messages sent by Irssi SILC client are now UTF-8
394 encoded (regardless whether the terminal supports UTF-8 or not).
395 Affected files are lib/silccore/silcchannel.h,
396 irssi/src/silc/core/silc-servers.c, silc-channels.c and
399 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
401 * Added lots of new statistics updating that was missing from
402 the server and router code. Affected files in silcd/.
404 * Sending SIGUSR1 signal to server now dumps the current
405 server statistics into /tmp directory. Affected file is
408 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
409 the SILC Hash Interface also. Added new functions
410 silc_hash_get_name, silc_hash_init, silc_hash_update and
411 silc_hash_final. Affected file lib/silccrypt/silchash.c.
413 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Added some better info printing for client during connecting.
416 Affected file silcd/server_util.c.
418 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
419 to silence a user on a channel. Affected files are
420 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
421 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
422 and silcd/packet_receive.c.
424 * Fixed a fatal bug in handling of malformed command payload.
425 Affected file silcd/command.c.
427 * Fixed a double free when announcing channel users to router.
428 Affected file silcd/server.c.
430 * After successful authentication to channel founder mode, check
431 that there isn't anyone else with founder mode on the channel.
432 The one that authenticated will become founder and anyone
433 else is demoted. Affected file silcd/command.c.
435 * Added error printing of any error that has occurred during
436 any command in client library. Affected file is
437 irssi/src/silc/core/client_ops.c.
439 * Removed some error printing from the client library and left
440 it for the application to worry (from the error status it
441 receives in 'command' client operation. Affected file is
442 lib/silcclient/command.c.
444 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
446 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
447 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
448 Starting key agreement with itself is denied. Affected file
449 is lib/silcclient/client_keyagr.c.
451 * Fixed some error checkings from the SFTP library which caused
452 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
453 and lib/silcsftp/sftp_util.c.
455 * Added new "debug" and "debug_string" settings to Irssi SILC
456 client which can be used to print runtime debugging on the
457 Irssi's screen. Available when compiled with --enable-debug
458 option. Affected file irssi/src/silc/core/silc-core.c.
460 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
462 * Fixed a missing variadic parameter in a function call that
463 caused server crash when a non-allowed connection arrived.

466 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Added WATCH list sending to backup routers from router.
469 The WATCH command is sent by the router to the backup
470 router. Affected file silcd/command.c.
472 * Mark the backup_router flag for RouterConnection entry
473 if the backup router stuff is defined in the config file.
474 Affected file silcd/serverconfig.c.
476 * Fixed some backup data sending around the code to work better
477 if the router is standalone router. Not all places were fixed.
478 Affected file silcd/packet_receive.c, silcd/packet_send.c,
481 * Fixed the router connecting when connecting to multiple
482 routers. It ignored every other router except the first
483 one. Affected file silcd/server.c.
485 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Made the private key generation after expiration optional.
488 If not created after expiration the old key will re-expire
489 at a later time (and thus key pair is not necessary to
490 change). Affected file irssi/src/silc/core/clientutil.c.
492 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
494 * The length arguments in bind() and connect() were wrong
495 and fixed now to used SIZEOF_SOCKADDR in the
496 lib/silcutil/unix/silcunixutil.c.
498 Tue Jun 4 18:36:05 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
500 * Fixed detach timeout handling to use Client ID and not
501 the actual client entry which may be freed in the callback.
502 Affected file silcd/command.c.
504 Thu May 30 15:53:45 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Merged c0ffee's multiple interface support patch.
507 Affected files in silcd/.
509 Wed May 29 18:08:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

514 Tue May 28 20:11:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
516 * Display the user mode on the status bar. Affected file
517 irssi/src/silc/core/silc-expandos.c.
519 Tue May 28 13:56:26 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
521 * If private message key is not set, but the flag is set in
522 the packet, ignore the packet since it cannot be decrypted.
523 Affected file lib/silcclient/client_prvmsg.c.
525 Thu May 23 12:00:14 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

528 the watcher list too. Affected file silcd/packet_receive.c.
530 * Do not allow normal server to force founder mode away
531 from router if the founder mode is already set. Affected
532 file silcd/packet_receive.c.
534 * Remove the client entry with watch notify types with short
535 timeout, and not directly, so that other notifys can be
536 retrieved too. Affected file lib/silcclient/client_notify.c.
538 * Display notification about data messages that cannot be
539 displayed. Affected files irssi/src/silc/core/client_ops.c,

552 file silcd/command.c.
554 Sat May 18 11:35:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
556 * Allow multiple identical pending commands to be registered
557 in client library. Affected file is lib/silcclient/command.c.
559 * Call the completion for resolving client information only
560 after all resolvers has finished. This fixes a crash in
561 the client. Added support for checking when the resolvers
562 are finished. Affected file is lib/silcclient/idlist.c.
564 * Wait by default 3 seconds before reconnecting to the server

1081 the implementation. Protocol TODO #9. Affected file is
1082 lib/silccore/silcchannel.h.
1084 Changed the client library to return the message length
1085 to application as well in the channel_message and private_message
1086 client operations. Affected files are
1087 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1088 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1089 and lib/silcclient/client_ops_example.c.
1091 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1092 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1093 the channel. Updated protocol specs and impelemented this
1094 to client and server. Protocol TODO #6. Affected files are
1095 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1096 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1098 Added new options m and M to CMODE command in Irssi SILC
1099 client to set these modes.
1101 * Deprecated all administrative commands from SILC protocol
1102 since they are highly implementation specific commands.
1103 Updated protocol specs. Moved the old commands in
1104 implementations to private range of command types. Affected
1105 files are silcd/command.c, lib/silcclient/command.c and
1106 lib/silcclient/command_reply.c. Protocol TODO #8.
1108 * Fixed a bug in server where sending unknown command crashes
1109 the server. Affected file silcd/command.c.
1111 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1113 * Added SILC_PROTOCOLVERSION macro to check protocol version
1114 of a socket connection. The affected file is
1115 lib/silcutil/silcsockconn.h.
1117 * Added better error logging in rekey protocol. Affected file
1120 * Do not check public key types in SKE during rekey. Affected
1121 file lib/silcske/payload.c.
1123 * Fixed the rekey protocol with PFS, which was totally broken.
1124 Affected file silcd/protocol.c.
1126 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1128 * Some client implementations quit network by doing first LEAVE
1129 and then immediately SIGNOFF (like Bombyx). We now do check
1130 after a short time after LEAVE notify and check whether the
1131 client is still valid after LEAVE, and if not we remove it from
1132 cache. Affected file is lib/silcclient/client_notify.c.
1134 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1136 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1137 it's good not to have security holes here.
1139 * Fixed a negative refcount situtuation for the config context.
1140 Affected file is silcd/serverconfig.c.
1142 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1144 * ROBOdoc documented lib/silcutil/silcutil.h.
1146 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1148 * Optimized even more the SilcPacketContext structure. Now
1149 totally saved 16 bytes of memory per context after optimization.
1150 Affected files are lib/silccore/silcpacket.[ch].
1152 * Made strict checks for valid SILC IDs. Affected file is
1153 lib/silccore/silcid.c.
1155 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Changed the object argument for silc_cipher_register,
1158 silc_hash_register, silc_hmac_register and silc_pkcs_register
1159 to const. Affected files are lib/silccrypt/silccipher.[ch],
1160 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1162 * Changed the silc_get_username and silc_get_real_name to
1163 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1165 * Fixed the Irssi SILC Client to use the silc_get_username and
1166 silc_get_real_name insted of glib routines since the glib
1167 routines only corrupt stack. Fixes the Irssi SILC to work in
1168 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1170 * Fixed the Irssi to not use g_get_home_dir since it crashes
1171 or returns garbage on cygwin and corrupts stack. Added function
1172 get_home_dir to Irssi routines. Affected files are
1173 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1175 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1177 * Made some structure optimizations. SFTP memory FS MemFSEntry
1178 entry structure. Optimized SilcTask structure. Optimized
1179 SilcPacketContext structure.
1181 Affected files lib/silcsftp/sftp_fs_memory.c,
1182 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1184 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1186 * And yet again reverted back the config thing since Johnny
1187 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1190 * Fixed memory leaks from config object. Affected files are
1191 silcd/serverconfig.[ch].
1193 * Added support for adding new connections to the server in rehash.
1194 After rehash they take effect.
1196 Added support for changing the maximum allowed connections in
1197 rehash. The number can grow but going smaller is not supported.
1199 Added function silc_server_num_sockets_by_remote to the
1200 silcd/server_util.[ch].
1202 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1204 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1206 * Added preliminary checking during config parsing for a valid
1207 public/private key and removed further checks in the code.
1208 Affected files are silcd/serverconfig.[ch], server.c.
1210 * Moved functions silc_server_drop() and silc_server_daemonise()
1211 from server.c to silcd.c since they are stricly related to
1212 the application activity.
1214 * Reverted a small part of the automatic ref/unref since
1215 it caused a double unref in some situations. Affected
1216 files are silcd/silcd.[ch], server.c, serverconfig.c.
1218 * Added some .cvsignore files in the lib directory.
1220 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1222 * Fixed silc_net_gethostbyaddr to correctly resolve by
1223 address. Affected file lib/silcutil/silcnet.c.
1225 * Fixed the notify relaying to client. The HMAC to be used
1226 with relayed packets ws wrong and caused decryption failure
1227 at the client end. Affected file is silcd/packet_receive.c.
1229 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1231 * Created new branch silc_protocol_1_0_branch.
1233 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1235 * Changed the silc_server_config_* routines to be SilcServer
1236 independent. They are now officially application specific code
1237 and not part of generic server implementation. Affected files
1238 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1240 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Added automatic referencing of config context in the
1243 silc_server_config_alloc, and automatic unreferencing in the
1244 silc_server_config_destroy. Affected files are
1245 silcd/serverconfig.[ch], silcd/silcd.c.
1247 * Fixed the silc_log_quick handling in the logging routines.
1248 It didn't log quickly when it was TRUE. Affected file is
1249 lib/silcutil/silclog.c. Also the flush delay was set even
1250 if it was 0 in config file. Affected file is
1251 silcd/serverconfig.c.
1253 * Added support for changing key pair of the server in rehash.
1254 Affected file silcd/server.c.
1256 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1258 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1259 too early, before getting the channel entry. Affected file
1260 is silcd/packet_receive.c.
1262 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1264 * Added functions silc_server_config_[ref/unref], these are used
1265 to prevent that the config object is destroyed.
1267 No longer directly affect global variables silc_log_quick and
1268 silc_log_delay, they are first cached inside the config object
1269 and then applied with silc_server_config_setlogfiles().
1271 silc_server_config_set_defaults() is now internal to
1272 serverconfig.c, there are no reasons to show this internal stuff
1275 Affected files are silcd/serverconfig.[ch].
1277 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1278 fprintf's to stderr, since some code may be executed again after
1279 the server went into the background. Affected files are
1282 * Added rehash support. Added function silc_server_rehash() that
1283 will perform all the basic tasks of the rehashing procedure.
1285 * Added command line option `-x, --hexdump'. This will enable the
1286 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1287 The option `--hexdump' implies `--debug'.
1289 * Fixed a bad bug in the logging APIs (silcutil library) where
1290 the application would crash after calling silc_log_reset_all().
1292 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1294 * Fixed the KICKED notify handling in client library to
1295 correctly remove the channel and all entries from the
1296 channel when I was kicked. This bug crashed the client.
1298 Fixed yet another but in KICKED notify handling to remove
1299 the kicked client correctly from the channel.
1301 Affected file is lib/silcclient/client_notify.c.
1303 * Fixed a minor bug in looking up correct client entry
1304 in KICKED notify in server. Affected file is
1305 silcd/packet_receive.c.
1307 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1308 sources correctly to distribution. Fixes --with-gmp option.
1310 * Removed the manual rehashing from ID Cache, and changed it
1311 to use the SILC Hash Table's auto rehash feature. Affected
1312 file is lib/silccore/silcidcache.c.
1314 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Fixed a bug in the silc_client_nickname_format function that
1317 handles the multiple same nickname formatting. Two clients
1318 with same nickname caused problems after the first one left
1319 and rejoined. It didn't format the nickname correctly.
1320 Affected file is lib/silcclient/idlist.c.
1322 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1324 * Don't change the topic if olod topic is same as new one.
1325 Affected file is silcd/packet_receive.c.
1327 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1329 * Added cross-reference support to the SILC Documentation
1330 generator. All types across all HTML files are now cross-
1331 referenced. Affected files util/robodoc/generator.c and
1332 scripts/silcdoc/silcdoc.
1334 * Added file lib/silcutil/silctypes.h to include all the
1335 arithmetic type definitions and some macros. Removed
1336 includes/bitmove.h and moved macros to silctypes.h.
1338 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1342 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1344 * Added `type' argument to silc_id_payload_parse_id function which
1345 now returns the type of the ID to the sent pointer. Affected
1346 file is lib/silccore/silcid.[ch].
1348 * Added check for CMODE_CHANGE notify type that mode change is
1349 allowed by the sender. Affected file silcd/packet_receive.c.
1351 * Added check for CUMODE_CHANGE notify type that mode change is
1352 allowed by the sender. Affected file silcd/packet_receive.c.
1353 Added the ID type as CUMODE_CHANGE notify type as argument
1354 to the `notify' client operation. Affected files are
1355 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1357 * Added function silc_client_add_server to the client library.
1358 Added support for resolving also channel and server info when
1359 received unknown entity in notify packet. Affected files are
1360 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1362 * Added function silc_command_get_status to return the command
1363 status from the command reply's argument payload. Affected files
1364 are lib/silccore/silccommand.[ch].
1366 * Added check for KICKED notify type that the kicking is
1367 allowed by the client. Affected file silcd/packet_receive.c.
1369 * Created function silc_get_input which can be used to get input
1370 (echo on or off) from user on command line. Affected files are
1371 lib/silcutil/silcutil.[ch].
1373 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Optimized silc_server_packet_relay_to_channel function.
1376 Added new function silc_channel_message_payload_encrypt which
1377 can be called directly if channel message payload needs to
1378 be encrypted and is already encoded (no need to call _encode
1379 function). Packet relaying is now done by router without any
1380 extra memory allocations. Affected files are
1381 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1382 silcd/packet_send.c.
1384 * Fixed the INVITE notify handling. It took wrong arguments
1385 as invite list and invite delete. Affected file is
1386 silcd/packet_receive.c.
1388 * Added check for TOPIC_SET notify type that the topic change is
1389 allowed by the client. Affected file silcd/packet_receive.c.
1391 * Added check for INVITE notify type that inviting is allowed by
1392 the client. Affected file silcd/packet_receive.c.
1394 * Changed the silc_server_client_on_channel to return the
1395 SilcChannelClientEntry as well. Moved the function
1396 silc_server_check_cmode_rights to server_util.[ch].
1397 Affected files are silcd/server_util.[ch], silcd/command.c.
1399 * Added function silc_server_check_umode_rights to check whether
1400 changing client's user mode is allowed. Added check for
1401 UMODE_CHANGE notify type that the umode change is allowed
1402 by the client. Affected files are silcd/server_util.[ch],
1403 silcd/packet_receive.c and silcd/command.c.
1405 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1408 ID length. It ignored that ID can be IPv6 based as well.
1409 Affected file lib/silccore/silcpacket.h.
1411 * Fixed the silc_id_id2str and silc_id_str2id to take the
1412 IPv6 address offset's into consideration. Affecte file is
1413 lib/silccore/silcid.c.
1415 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1417 * Fixed the internal Unix scheduler functions to check for
1418 NULL context they may receive. The affected file is
1419 lib/silcutil/unix/silcunixschedule.c.
1421 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1423 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1424 can specify different directory with --home command line
1425 parameter. Affected files irssi/src/silc/core/client_ops.c,
1428 * SILC-specific commands aren't now executed if the active server
1429 isn't of SILC-type, so there won't be problems with having
1430 IRC and SILC protocol support in same client. Affected files
1431 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1434 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1436 * Improved the signal support in SILC Schedule. Added new
1437 function silc_schedule_signal_call which is used by application
1438 to mark a signal to be called. It is now safe to perform
1439 any kind of tasks in signal callbacks since it is guaranteed
1440 that the application specified signal callback is called
1441 after the signal is over. Affected files are
1442 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1444 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1446 * Added `name' field to SilcChannelPrivateKey to represent
1447 application given name for the key. Moved also the context from
1448 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1449 Added the `name' argument also to the function
1450 silc_client_add_channel_private_key.
1452 Added function silc_client_current_channel_private_key to set the
1453 current channel private key in use.
1455 Added "change" command to KEY command which can be used to change
1456 the current channel private key. Bound the command also to
1457 alt+K (Alt+Shift+k).
1459 Also affected files lib/silcclient/client_channel.c,
1460 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1462 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1464 * Added silc_rng_get_byte_fast function in to the
1465 lib/silccrypt/silcrng.[ch].
1467 * Changed the interface of silc_packet_assemble and the
1468 silc_packet_send_prepare. If silc_packet_assmble is now
1469 called the application does not call silc_packet_send_prepare
1470 because the library will call it automatically. These
1471 interfaces now also return a reference to the outgoing buffer
1472 which includes the assembled packet, which the application can
1473 use to encrypt the packet.
1475 Affected files are lib/silccore/silcpacket.[ch],
1476 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1477 silcd/packet_send.c, server_backup.c and packet_receive.c.
1479 * Fixed a packet sending bug on very high load, where outgoing
1480 packet queue wasn't handled correctly and packets got corrupted.
1481 Affected files are lib/silcutil/*/silc*sockconn.c,
1482 lib/silcclient/client.c and silcd/server.c.
1484 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1486 * Added macro SILC_PACKET_DATALEN which can be used during
1487 packet assembling to check whether the data to be added to
1488 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1489 len is truncated until it fits it.
1491 Added checks for maximum length of channel message payload and
1492 private message payload also.
1494 Added checks for maximum packet length in server and in
1497 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1498 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1499 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1500 lib/silcclient/client_prvmsg.c.
1502 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Added silc_server_packet_queue_purge call to the
1505 silc_server_disconnect_remote to assure that all data in the
1506 queue before disconnecting is sent to the network. Affected
1507 file silcd/server.c.
1509 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1511 * Added the deleting of server's own ID cache entry to the
1512 silc_server_free function. Free also everything else that
1513 has been allocated in silc_server_init. The affected file
1516 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1518 * Added functions silc_parse_version_string, silc_version_to_num,
1519 and silc_ske_parse_version to parse SILC protocol style version
1520 strings. Affected files lib/silcutil/silcutil.[ch] and
1521 lib/silcske/silcske.[ch].
1523 * Added new configuration params: version_protocol, version_software
1524 and version_software_vendor to specify what version the remote
1525 host must at least be to be able to connect to server. The vendor
1526 string can be regex matched too. Added new function
1527 silc_server_connection_allowed to check maximum number of allowed
1528 connections, and allowed versions for incoming connections.
1529 Affected files are silcd/server.c, server_util.[ch] and
1532 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * Added preliminary support for signals in scheduler. The
1535 signals we care about are now blocked always when the scheduler
1536 is locked. This way we can synchronise the use of signal with
1537 scheduler. It is guaranteed that when signal occurs the scheduler
1538 is not locked, and thus new tasks can be safely added to the
1541 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1542 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1543 Added new platform specific routines
1544 silc_schedule_internal_signals_[un]block and
1545 silc_schedule_internal_signal_[un]register.
1547 Added new functions to SILC Schedule API:
1548 silc_schedule_signal_[un]register. Each signal that application
1549 is going to use should be registered to the scheduler.
1551 Affected files are lib/silcutil/silcschedule.[ch],
1552 lib/silcutil/*/silc*schedule.c.
1554 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1556 * Check for unauthenticated client and server in the
1557 silc_server_new_client and silc_server_new_server functions.
1558 Affected file silcd/packet_receive.c.
1560 * Added function silc_string_is_ascii to check whether given
1561 string is 7-bit ASCII string. Affected files are
1562 lib/silcutil/silcutil.[ch].
1564 * Added function silc_id_is_valid_server_id into the
1565 silcd/serverid.c and added checking for valid Server ID's in
1566 silc_server_new_server. The Server ID must always be based
1567 on the server's public IP address.
1569 * Added logging of DISCONNECT packet message in the server.
1570 Affected file silcd/server.c.
1572 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1574 * Changed all library interfaces that use Global RNG to also
1575 accept SilcRng as argument. Affected files are
1576 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1577 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1578 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1579 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1580 lib/silccrypt/rsa.c.
1582 * Added function silc_pkcs_generate_key to the
1583 lib/silccrypt/silcpkcs.[ch] for applications so that they
1584 don't need to do pkcs->pkcs->init calls anymore.
1586 * Remove SilcSocketConnection from the SFTP API since it really
1587 wasn't needed there. The application has the information
1588 saved in its contexts anyway and the SFTP layer doesn't need
1589 know about it. Affected files lib/silcsft/silcsftp.h and
1590 lib/silcsftp/sftp_[server/client].c.
1592 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1600 algorithm list on EPOC. Affected files are
1601 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1604 * Fixed the handling of third parameter of KICKED notify, since
1605 it was mistakenly updated to SILC Protocol 1.0 even though it
1606 is to be included in 1.1. Since it is not in 1.0 it is not
1607 mandatory, and this fix now handles it only if it is provided,
1608 and it is not error if it is not provided. Affected file
1609 lib/silcclient/client_notify.c.
1611 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1621 sending any messages. Fixes a crash, but doesn't fix some
1622 other underlaying bug that is lurking there. Affected
1623 file silcd/packet_send.c.
1625 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1627 * $usermode, $cumode and $cumode_space expandos shouldn't do
1628 anything with non-SILC server records. Affected file
1629 irssi/src/silc/core/silc-expandos.c
1631 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1634 IPv6 bound sockets as well. Now they can return IPv6 addresses
1635 as well. Affected file lib/silcutil/silcnet.c.
1637 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1638 Affected lib/silcutil/unix/silcunixnet.c.
1640 * Fixed ID rendering (at least on some platforms, not NetBSD)
1641 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1643 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Added silc_hash_public_key and silc_hash_public_key_compare
1646 functions to be used with SilcHashTable. They can be used to
1647 hash public keys and compare public keys in hash table. Affected
1648 file lib/silcutil/silcutil.[ch].
1650 * Added support for specifying multiple public keys for Client
1651 connection section in server configuration file. This makes it
1652 possible to accept multiple public keys from same host, or to
1653 make a section that accepts any incoming host, and have the
1654 accepted public keys listed in the section.
1656 Added functions silc_sever_[find/get]_public_key, added the
1657 support for this actually to all connection sections but only
1658 the Client section is currently allowed to specify multiple
1661 Affected files are silcd/server.c, server_internal.h,
1662 command.c, protocol.c, server_util.[ch], packet_receive.c.

1668 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1670 * If silc_debug is TRUE, also output standard logging messages
1671 to stderr with the debug output.
1673 Made silc_log_reset_all() flushing all channels before returning.
1674 Also fixed some documentation typos.
1676 Affected files are lib/silcutil/silclog.[ch].
1678 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1680 * Fixed the server to check correctly the amount of connections
1681 from single host, by checking also the type of the connection.
1682 Fixed also the comparison of number of connections and number
1683 of allowed connections. Affected files are silcd/server.c,
1686 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1688 * Fixed the USERS command reply to save the user's mode on the
1689 channel as well. Fixed JOIN command reply to check whether a
1690 client is on channel already and not join it twice. Affected
1691 file lib/silcclient/command_reply.c.
1693 * Added new file silc-expandos.c into irssi/silc/core/ to return
1694 various stuff for various signal for the statusbar etc. updating.
1695 Now Irssi SILC client prints channel user modes etc. on the
1698 * The user mode (like server/router operator changes) is now shown
1699 on the Irssi SILC client's statusbar. The affected files are
1700 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1702 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1704 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1705 to SILC_SCHEDULE_[UN]LOCK macros.
1707 * Added more error printing to logs in server code. Affected
1708 files silcd/server.c and silcd/protocol.c.
1710 * Fixed -S option parsing in Irssi SILC Client. Affected file
1711 irssi/src/silc/core/silc-core.c.

1738 * Changed all integer type names:
1739 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1740 to avoid collisions with other libraries using same type names
1743 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1745 * Added `prefer_ipv6' argument to the functions
1746 silc_net_gethostbyname[_async]. If it is TRUE it will return
1747 IPv6 address over IPv4. If FALSE IPv4 address is returned
1748 even if IPv6 address was found. Affected files
1749 lib/silcutil/silcnet.[ch].
1751 * Added support silc_net_create_connection[_async] to fallback
1752 to IPv4 address if IPv6 address could not be used (like if

1762 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1764 * Added automatic extern "C" { ... } for C++ compilers so the
1765 application does not need to define them. Affected file
1766 includes/silcincludes.h.
1768 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1769 old name went against naming convention. Applications now
1770 include "silcclient.h" instead of "clientlibincludes.h".
1771 Removed includes/clientlibincludes.h, it is redundant now.
1773 * Renamed includes/version.h to silcversion.h.
1775 * Added really preliminary support for OS/2 into the util
1776 library. Only thread & mutex API is implemented, others
1777 are still to be implemented. Created the lib/silcutil/os2/
1778 directory. Created also file includes/silcos2.h.
1780 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1811 * Added `user_count' to the SilcChannelEntry which now tells the
1812 number of users on the channel. The user count is now saved
1813 in normal server of global channels as well. Affected files
1814 silcd/server.c, idlist.h, packet_receive.c and command.c.
1816 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1817 include file utility functions.
1819 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1820 instead of calling directly OS routines.
1822 * Fixed NICK change printing in Irssi SILC Client. Fixed
1823 KICKED notify printing in Irssi SILC Client. Affected file
1824 irssi/src/silc/core/client_ops.c.

1830 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1832 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1833 the SKE interface a bit.
1835 * Fixed padding problem in PKCS#1. The padding was not actually
1836 random since the random number generator was used incorrectly.
1837 This security bug affects only when encrypting with PKCS#1, and
1838 it is not currently used at all in SILC. SILC only use signing
1839 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1841 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1899 is now done in silc_core_init() which also fixes autoconnecting
1902 Affected files irssi/src/silc/core/silc-core.c,
1903 irssi/src/fe-text/silc.c.
1905 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1907 * Added new configuration options and blocks:
1908 keepalive_secs, reconnect_count, reconnect_interval,
1909 reconnect_interval_max, reconnect_keep_trying and
1910 require_reverser_lookup. Added ConnectionParam block, and
1911 implemented the connection parameters when connecting as
1912 initiator and when accepting connections as responder.

1915 whether given configuration value has been given already.
1917 Affected files silcd/serverconfig.[c], server.[c].
1919 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1920 algorithm parts and created new file silcalgs.conf, that
1921 is now included from the example_silcd.conf.in.
1923 * Optimized the silc_server_connect_to_router_second to take
1924 the connection configuration object from the SilcServerConnection
1925 object instead of finding it during the connecting phase.
1926 Added the configuration object to SilcServerConnection struct.
1927 Affected files silcd/server_internal.h, server.c.
1929 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1931 * Add the client on channel after it was resolved at the
1932 channel message receiving, and it was not already on the
1933 channel. Affected file lib/silcclient/client_channel.c.
1935 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1951 authentication to be set at the same time.
1953 Added `prefer_passphrase_auth' setting in config file which
1954 can be used to set to prefer passwd auth if both passwd and
1955 public key is set. If not set, public key is preferred.
1956 This has effect only when being initiator (responder will try
1959 Added support for authentication with passphrase and public key
1960 at the same time. The passphrase is tried first always since
1961 it is faster to check.
1963 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1965 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2011 * Fixed the file transfer's key agreement payload to include
2012 zero port also if the hostname is NULL because it could not
2015 Call file transfer monitor callback now also if error occurs
2016 during key agreement protocol.
2018 Changed the silc_client_file_send interface to return the
2019 SilcClientFileError instead of session id. The session ID
2020 is returned into pointer provided as argument.

2037 file lib/silcutil/silclog.c.
2039 * Fixed the channel message payload decryption in the function
2040 silc_channel_message_payload_decrypt to not modify the original
2041 buffer before it is verified that the message decrypted
2042 correctly. Otherwise, next time it is called with correct
2043 channel key it won't encrypt since the payload is corrupted.
2044 Affected file lib/silccore/silcchannel.c.
2046 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2061 the callback returned.
2063 Do not allow auto rehashing of hash table during the
2064 silc_hash_table_foreach operation, for same reasons as it is
2065 not allowed for SilcHashTableList. Affected files are
2066 lib/silcutil/silchashtable.[ch].

2089 users list to SilcHashTable. The affected files are
2090 lib/silcclient/idlist.[ch].
2092 * Fixed a bug in hash table tarversing. While the hash table
2093 is traversed with SilcHashTableList the table must not be
2094 rehashed. It is now guaranteed that auto rehashable tables
2095 are not rehashed while tarversing the list. Also defined that
2096 silc_hash_table_rehash must not be called while tarversing
2097 the table. Added function silc_hash_table_list_reset that must
2098 be called after the tarversing is over. The affected files are
2099 lib/silcutil/silchashtable.[ch].
2101 * Changed all hash table traversing to call the new
2102 silc_hash_table_list_reset in server and in client library.
2104 * Added function silc_client_on_channel to return the
2105 SilcChannelUser entry if the specified client entry is joined
2106 on the specified channel. This is exported to application as
2107 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2109 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2111 * Fixed founder regaining problem with JOIN command on normal
2112 server. The notify for mode change must be sent always and
2113 not only if !cmd->pending. Affected file silcd/command.c.
2115 * Fixed the WHOWAS command's reply sending to support the
2116 lists correctly. Affected file silcd/command.c.
2118 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2120 * When sending JOIN command to router for processing the
2121 sender's old command identifier was not saved back to the
2122 sender's command context, fixed now. The affected file is
2125 * Create the key in JOIN command of the router did not return
2126 the channel key, added check for this. Affected file is
2129 * Fixed a channel ID update bug in JOIN command reply. Do
2130 not directly upgrade the ID but call the function
2131 silc_idlist_replace_channel_id if the ID was changed.
2132 Affected file silcd/command_reply.c.
2134 * Fixed memory leaks from command calling if it would fail.
2135 Affected file silcd/command.c.
2137 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2139 * Applied patches from cras:
2141 Memory leak fixes around libaries, irssi window resize fix,
2142 new silclist.h and silcdlist.h, all extern inline changed to
2145 * Removed dotconf from lib/dotconf, not needed anymore.
2147 * Removed TRQ from lib/trq, not needed anymore.
2149 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2150 with server connections. Later this will be configurable
2151 in config file after new config file is done. Affected file
2154 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed a crash in server related to channel announcements.
2157 Affected file silcd/server.c.
2159 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed memory leaks in silc_server_create_new_channel*
2162 functions. Affected file silcd/server.c.
2164 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2165 which ID was changed. This way the router will send the
2166 user list for the channel again, and server won't be in
2167 desync in some rare circumstances. Affected file is
2168 silcd/packet_receive.c.
2170 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2172 * Check for NULL socket pointer in the function
2173 silc_server_packet_send_to_channel_real. Affected file
2174 silcd/packet_send.c.
2176 * Fixed the BAN notify handling to correctly remove ban
2177 list. Affected file silcd/packet_receive.c.
2179 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2181 * Fixed some header addition to Toolkit distribution in
2182 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2184 * Added lib/silcclient/client_ops_example.h as an template
2185 file for application programmers to quickly start using
2186 the SilcClientOperation functions in their application.
2187 Updated the lib/silcclient/README as well to tell about this
2188 nice file made available.
2190 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2192 * Call silc_server_remove_from_channels when removing client
2193 entry when NO_SUCH_CLIENT_ID was received. Affected file
2194 is silcd/command_reply.c.
2196 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2198 * Added server & router operator statistics updating. Affected
2199 file silcd/packet_receive.c and silcd/command.c.
2201 * Fixed the SERVER_SIGNOFF notify handling on normal server
2202 not to save the history information for clients. Same was
2203 fixed earlier in remove_clients_by_server function, but not
2204 here. Affected file silcd/packet_receive.c.
2206 * Raised the default connection-retry count from 4 to 7 in
2207 server. Affected file silcd/server.h.
2209 * Cancel any possible reconnect timeouts when we start the
2210 key exchange. Affected file silcd/server.c.
2212 * Do not reconnect on connection failure when SCONNECT was
2213 given. Affected files silcd/server.[ch].
2215 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2217 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2219 * Fixed the NICK command to always give the unformatted
2220 nickname to the one giving the NICK command. If unformatted
2221 nickname is cached already it will be formatted and the
2222 local entry will always get the unformatted nickname.
2223 Affected file lib/silcclient/idlist.c.
2225 * Fixed some double frees from client library commands.
2226 Affected file is lib/silcclient/command.c.
2228 * Fixed CUMODE command in server to assure that no one can
2229 change founder's mode than the founder itself, there was a
2230 little bug. Affected file silcd/command.c.
2232 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2234 * Removed the SilcClientCommandDestructor from the client
2235 libary, it is not needed anymore. Affected files are
2236 lib/silcclient/silcapi.h, command[_reply].[ch],
2237 client_notify, idlist.c.
2239 * Fixed GETKEY command to first resolve client, and then
2240 resolve the server only if the client was not found, instead
2241 of resolving both at the same time. Affected file is
2242 lib/silcclient/command.c.
2244 * Added silc_client_start_key_exchange_cb and lookup the
2245 remote hostname and IP address before starting the key
2246 exchange with server. The affected file is
2247 lib/silcclient/client.c.
2249 * The server's public key is now saved using the IP address
2250 of the server and not the servername for the filename.
2251 The hostname public key filename is checked as an fall back
2252 method if the IP address based filename is not found.
2254 Fixed the GETKEY command to save the fetched server key
2255 in correct filename.
2257 Print the remote server's hostname now when new key is
2258 received during connection process. Affected file is
2259 irssi/src/silc/core/client_ops.c.
2261 * Return always our own public key to the client if it asks
2262 for it with GETKEY command. Affected file silcd/command.c.
2264 * Removed the use_auto_addr variable from default config
2265 file since it was in wrong section. Affected file is
2268 * Fixed TOPIC_CHANGE notification to not route it when it
2269 was sent using silc_server_send_notify_to_channel function.
2270 Affected file silcd/command.c.
2272 * Fixed silc_server_send_notify_kicked to send the kicker's
2273 Client ID also, it was missing. Affected files are
2274 silcd/command.c, silcd/packet_send.[ch].
2276 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2278 * Do not save client history information in SERVER_SIGNOFF.
2279 Fixes the bug in normal server that it does not detect
2280 the client becoming valid after the server becomes back
2281 online. Affected file silcd/server_util.c.
2283 * Added `sock_error' field into the SilcSocketConnection
2284 context. When error occurs during socket operation (read
2285 or write) the error is saved. Added also new function
2286 silc_socket_get_error to return human readable socket error
2287 message. Affected files are lib/silcutil/silcsockconn.[ch],
2288 lib/silcutil/unix/silcunixsockconn.c, and
2289 lib/silcutil/win32/silcwin32sockconn.c.
2291 * The server now prints the socket error message in the
2292 signoff for client. Affected file silcd/server.c.
2294 * Fixed the `created' channel information sending from router
2295 to server in JOIN command. Checks now whether the channel
2296 really was created or not and set it according that.
2298 Fixed the JOIN command to use the client entry's current
2299 ID during the joining procedure instead of the one it sent
2300 in the command (it is checked though), since it can change
2301 between the packet processing and command processing, and
2302 would just case unnecessary pain in the client end. Affected
2303 file silcd/command.c.
2305 * Fixed a channel key payload sending to use correct channel
2306 ID when the server was forced to change the channel's ID by
2307 router. Router sent the key payload with the old Channel ID.
2308 Affected file silcd/packet_receive.c.
2310 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2312 * Call silc_server_save_channel_key only if the key payload
2313 was provided in the JOIN command's command reply. Affected
2314 file silcd/command_reply.c.
2316 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2318 * Fixed silc_mp_sizeinbase to return the value correctly with
2319 MPI. Affected file lib/silcmath/mp_mpi.c.
2321 * Fixed the stop_server signal to correctly stop the scheduler
2322 and gracefully stop the server when SIGTERM or SIGINT signals
2323 are received. Affected file silcd/silcd.c.
2325 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2327 * Simple handling of TERM and HUP signals. Also added some log
2328 flushing call around. Affected file is
2331 * Fixed small bugs in silclog.c. Now buffering output will take
2332 effect after 10 seconds since startup: This will ensure that
2333 no important startup messages are lost. Also output redirection
2334 will preserve original format ([Date] [Type] message).
2335 Affected file is lib/silcutil/silclog.c.
2337 * Added two options to the config file, in the logging section:
2338 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2339 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2341 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2343 * Do not print the warning about log files not being initialized
2344 more than once to avoid excess logging. Affected file is
2345 lib/silcutil/silclog.c.
2347 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2348 the SIM copying in make install in Makefile.am.pre.
2350 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2352 * Rewritten silclog APIs. Globally interesting changes follows:
2353 silc_log_set_files() changed to silc_log_set_file().
2354 silc_log_set_callbacks() changed to silc_log_set_callback().
2355 ROBOdoc documented silclog header file.
2356 SilcLogCb now returns bool to wether inihibit the default
2357 handler or not (to keep the old behaviour return always TRUE).
2358 The new APIs should also fix the problem of the
2359 silcd_error.log file that was written in the current directory.
2362 Log files streams will remain opened after silc_log_set_file()
2363 call, means less CPU usage notably on high traffic servers.
2364 File streams are now full buffered, and flushed to the disk
2365 every 5 minutes, lesses HD activity and CPU usage.
2366 Messages can be redirected, allowing admins to configure
2367 one single logfile for all server messages.
2368 the silc_log_quick global variable to activate fast-logging.
2369 Affected files lib/silcutil/silclog.[ch]
2371 * Changed some code to conform new silclog APIs. Affected
2372 files are doc/example_silcd.conf.in, silcd/server.c
2373 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2376 * Fixed a memory leak that could occur in some situations.
2377 Affected file silcd/serverconfig.c.
2379 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2381 * Added the silc_client_del_client to remove the client from
2382 all channels as well. Affected file lib/silcclient/idlist.c.
2384 * Fixed the client library to correctly remove the client
2385 from all channels when the client entry is being destroyed.
2386 Affected file lib/silcclient/client_notify.c, command.c.
2388 * Added auto-nicking support to the client library. If the
2389 applicatio now sets client->nickname it will be sent to the
2390 server after connecting by the library. This way for example
2391 SILCNICK (or IRCNICK) environment variables will have effect
2392 and always change the nickname automatically to whatever
2393 it is wanted. Affected file lib/silcclient/client.[ch].
2395 * Renamed silc_server_command_bad_chars to the
2396 silc_server_name_bad_chars and moved it to the
2397 silcd/server_util.[ch]. Added also new function
2398 silc_server_name_modify_bad to return nickname that
2399 includes bad characters as new nickname without those
2400 bad characters. This check and modify is now used in
2401 silc_server_new_client when the username is initially set
2402 as nickname, so it must be checked to be valid nickname.
2403 Affected file silcd/packet_receive.c.
2405 * The nickname length is now taken from the packet for real
2406 and not trusted to strlen() since it clearly can return
2407 wrong length for nickname including bad characters. This
2408 also applies to channel names. Affected file silcd/command.c.
2410 * Removed the lib/silcsilm/modules directory. Modules are now
2411 compiled into the lib/silcsim. Fixed the copying of the
2412 modules to follow symbolic links in Makefile.am.pre.
2414 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2416 * Fixed silc_string_regexify list creation. Fixes bugs with
2417 BAN and INVITE commands in server. The affected file is
2418 lib/silcutil/unix/silcunixutil.c.
2420 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Removed the command destructor entirely from the server's
2423 command and command reply routines. It is not needed, and
2424 its usage was buggy and caused crashes. Affected files are
2425 silcd/command[_reply].[ch].
2427 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Cancel protocol and NULL sock->protocol if timeout
2430 occurred during protocol. Affected file silcd/server.c.
2432 * Cancel protocol timeouts always before calling the final
2433 callback, to assure that after final callback is called
2434 no other state will be called for the protocol anymore.
2435 Affected file silcd/protocol.c.
2437 * Print error log if incoming connection configuration could
2438 not be found. Affected file silcd/server.c.
2440 * Fixed JOIN command to correctly save the founder mode
2441 to the client on normal SILC server, when the channel
2442 was created by the router. Affected file silcd/command.c.
2444 * Fixed LIST command (hopefully) to send correct reply
2445 packets. Affected file silcd/command.c.
2447 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * The silc_packet_receive_process now returns FALSE if the
2450 read data was invalid packet, and TRUE if it was ok.
2452 The server now checks that if unauthenticated connection
2453 sends data and its processing fails the server will close
2454 the connection since it could be a malicious flooder.
2456 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2458 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Make sure the warning about error opening a log file is
2461 printed only once and not everytime it fails (produces
2462 too much useless log). Affected file lib/silcutil/silclog.c.
2464 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2466 * Made the silc_server_daemonise() function more readable.
2467 Affected file silcd/server.c.
2469 * Pid file is now optional, the user may comment it out from
2470 the config file. Removed define SILC_SERVER_PID_FILE, we
2471 don't need a default any longer. Affected file
2472 configure.in.pre, lib/Makefile.am.pre.
2474 * Make some use of the pid file. The server now dies at startup
2475 if it detects a valid pid file on his path. The server would
2476 die anyway in this circumstance, because of the bind() failure.
2477 Affected file silcd/silcd.c.
2479 * No longer compiling lib/dotconf.
2481 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Fixed JOIN command parsing not to crash. Affected file
2484 lib/silcclient/command.c.
2486 * Fied the NICK_CHANGE notify to add the new client entry
2487 even it is resolved. This removes an <[unknown]> nick
2488 thingy bug in the client. Affected file is
2489 lib/silcclient/client_notify.c.
2491 * Do not try to allocate 0 bytes (efence does not like it)
2492 in lib/silccore/silccomand.c when encoding payload.
2494 * Do not take IRCNICK as nickname in Irssi SILC client since
2495 it is not possible to set nickname before hand connecting
2496 the server (TODO has an entry about adding auto-nicking
2499 * Changed the silc_server_command_pending to check whether
2500 there already exists an pending entry with the specified
2501 command, command identifier and pending callback. This is
2502 to fix IDENTIFY and WHOIS related crashes that may register
2503 multiple pending commands with same identifier. Affected
2504 file silcd/command.c.
2506 * Fixed the server to reconnect to the router even if it
2507 was already reconnecting and EOF was received. This to
2508 fix a possibility that the server wouldn't ever try to
2509 auto-reconnect to the router. Affected file silcd/server.c.
2511 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Fixed the server's password authentication to use the
2514 length of the locally saved password, and not the one
2515 sent in the packet. Affected file silcd/protocol.c.
2517 * Fixed same password authentication problem in the
2518 Authentication Payload handling routines in
2519 lib/silccore/silcauth.c.
2521 * Yet another password authentication problem fixed with
2522 channel password handling in silcd/command.c.
2524 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * If first character of string in silc_parse_userfqdn is '@'
2527 then do not parse it. Affected file is
2528 lib/silcutil/silcutil.c.
2530 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Fixed minor bug in IDENTIFY command reply sending, which
2533 caused various weird problems during JOIN when it was
2534 resolving names for users. Affected file silcd/command.c.
2536 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Fixed the IDENTIFY command reply sending to chech better valid
2539 clients. It was possible to send incomplete list of replies.
2540 Affected file silcd/command.c.
2542 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Added silc_client_command[s]_[un]register functions now to
2545 dynamically register the commands in client library. Removed
2546 the static table of commands. This allows the client library
2547 to call commands without causing the application to know about
2548 what commands library has called.
2550 Removed the INFO command reply kludge to detect when the command
2551 was called by library. Now library use its own command reply
2552 function for INFO command.
2554 Added function silc_client_command_call to call a command.
2555 Application can use it to call command, not access the structure
2558 Now all commands that are sent by the client library (not
2559 explicitly sent by application) use own command reply functions.
2561 Affected files around lib/silcclient/ and in
2562 irssi/src/silc/core/.
2564 * Fixed the WHOIS command reply sending to chech better valid
2565 clients. It was possible to send incomplete list of replies.
2567 Fixed the WHOIS and IDENTIFY to send the request to router
2568 if normal server did not do it and did not find any results.
2570 Affected file silcd/command.c.
2572 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Moved the internal data from SilcClient context into its
2575 own file, not accesible to application. Affected files
2576 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2577 and other files in client library.
2579 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added doc/examples installation target in Makefile.am.pre.
2584 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2587 commands the found client entry will be removed from the
2588 cache, after notifying application about the error. Affected
2589 file lib/silcclient/command_reply.c.
2591 * Changed the /MSG to check for exact nickname user gave, and
2592 not let `nick' match `nick@host' if it is only one found. Now,
2593 user must type the exact nickname (like nick@host2) even if
2594 there are no more than one same nicks found. This is to avoid
2595 a possibility of sending nickname to wrong nickname since
2596 `nick' could match `nick@host'. Affected file is
2597 irssi/src/core/silc-servers.c.
2599 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Do not print "you are now server operator" or similar when
2602 giving /away command. Affected files are
2603 irssi/src/silc/core/client_ops.c, silc-servers.h.
2605 * Made the silc_server_command_pending_error_check to send
2606 the same command reply payload it received back to the
2607 original sender of the command. This way all arguments
2608 that was received by the server will be received by the
2609 client too. Affected file silcd/command.c.
2611 * Added the silc_idcache_add to return the created cache entry
2612 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2614 * Add global clients to expire if they are not on any channel.
2615 This is because normal server will never know if they signoff
2616 if they are not on any channel. The cache expiry will take
2617 case of these entries. This is done by normal servers only.
2618 The affected files are silcd/command_reply.c,
2619 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2621 * If server receives invalid ID notification for WHOIS or
2622 IDENTIFY and the ID exists in the lists, it is removed.
2623 Affected file silcd/command_reply.c.
2625 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2626 in client then client entry that it matches is searched and
2627 the nickname is printed on the screen for user. Affected
2628 file irssi/src/silc/core/client_ops.c.
2630 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Use cache entry expire time in the LIST command reply to
2633 purge old entries from the cache after the LIST command
2634 reply has been received. This way we don't have non-existent
2635 entries in the cache for too long. Affected file is
2636 silcd/command_reply.c.
2638 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * If we are normal server, and we've not resolved client info
2641 in WHOIS or IDENTIFY from router, and it is global client,
2642 we'll check whether it is on some channel. If it is not
2643 then we cannot be sure about its validity and will resolve it
2644 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2645 file silcd/command.c.
2647 * Search channel by name (if possible) rather than by ID
2648 in IDENTIFY command's command reply. Affected file is
2649 silcd/command_reply.c.
2651 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2654 Updated specs and implemented it. Affected file silcd/command.c,
2655 silcd/packet_send.c and silcd/packet_receive.c.
2657 * Implemented the <founder auth> payload handling in the JOIN
2658 command. If provided all conditions for channel joining
2659 except requirement to provide correct passphrase can be
2660 overrided by the channel founder. Updated the protocol specs.
2661 Affected file silcd/command.c.
2663 Added support for founder auth in JOIN command in client
2664 library. Fixed the parsing of the JOIN command now to support
2665 all options as they should be. The affected file is
2666 lib/silcclient/command.c.
2668 * Optimized the WHOIS and IDENTIFY commands to send the request
2669 to router only if it includes nicknames or other names. If
2670 they include only IDs then check the local cache first before
2671 routing. Affected file is silcd/command.c.
2673 * Added channels topic announcements. Affected file is
2674 silcd/packet_receive.c and silcd/server.c.
2676 * Fixed the silc_server_send_notify_topic_set to really destine
2677 the packet to channel. Affected file silcd/packet_send.c.
2679 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2680 library. Affected file lib/silcclient/client_notify.c.
2682 * Added UMODE announcements. Affected file silcd/server.c.
2684 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Memory leak fixes in:
2688 lib/silcutil/silcsockconn.c

2692 lib/silccrypt/silcpkcs.c
2693 lib/silccore/silccommand.c
2694 lib/silccore/silcidcache.c
2699 * ROBOdoc documented the lib/silcske/groups.h file and a
2700 bit changed the interface for better.
2702 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2704 * Update the client entry context in the ID cache after
2705 nick change. Affected file lib/silcclient/command.c.
2706 Fixes the CUMODE command when regaining founder privileges,
2707 and a little WHOIS problem.
2709 * Fixed silc_net_gethostbyname to correctly call the
2710 inet_ntop. Affected file lib/silcutil/silcnet.c.
2712 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2714 * Added IPv6 support checking to the configure.in.pre, added
2715 also --enable-ipv6 option to override the check. Affected
2716 file configure.in.pre.
2718 * The silc_thread_create now calls the start function
2719 directly if threads support is not compiled in. Removes
2720 ugly #ifdef's from generic code. Affected files are
2721 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2723 * Added silc_net_gethostby[name/addr]_async to asynchronously
2724 resolve. Affected files are lib/silcutil/silcnet.[ch].
2726 * Added support for rendering IPv6 based server, client and
2727 channel IDs. Affected file lib/silcutil/silcutil.c.
2729 * Added support for creating IPv6 based server IDs. Affected
2730 file is silcd/serverid.c.
2732 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2734 * Added silc_net_gethostby[addr/name] into the
2735 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2736 routines. Added silc_net_is_ip[4/6]. Affected file is
2737 lib/silcutil/unix/silcunixnet.c. All routines that take
2738 address as argument now supports both IPv4 and IPv6 addresses.
2740 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2742 * Fixed LIST command reply sending in server. Affected file
2745 * Server now sends the kicker's client ID in the KICK notify
2746 to the kicked client. Affected file silcd/command.c.
2748 * The client library now parses the kickers client ID and
2749 UI displays it. Affected files lib/silcclient/client_notify.c
2750 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2752 * Made all payload parsing function prototypes consistent.
2753 They all take now const unsigned char * and uint32 pair as
2754 the payload data instead of SilcBuffer. Changes all around
2755 the source tree. Other unsigned char* -> const unsigned char*
2756 changes around the tree as well.
2758 * Optimized SFTP client and server packet sending not to
2759 allocate new buffer for each packet but to recycle the
2760 first allocated buffer. Affected files are
2761 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2763 * Optimized the SFTP client to use SilcList instead of
2764 SilcDList for requests, because it is faster. Affected file
2765 is lib/silcsftp/sftp_client.c.
2767 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2768 into lib/silccore/silcid.[ch].
2770 Renamed silcpayload.[ch] into silcargument.[ch].
2772 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * If client entry is deleted with active key agreement
2775 session, abort the session.
2777 The silc_client_abort_key_agreement now calls the completion
2778 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2780 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2783 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Don't use __restrict in older GCC's. Affected file is
2786 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2788 * silc_net_localhost now attempts to reverse lookup the
2789 IP/hostname. Affected file lib/silcutil/silcnet.c.
2791 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2792 command. It can be used to gain founder privileges at
2793 the same time when joining the channel.
2795 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2796 kicker's client ID as well. Updated protocol specs.
2798 Defined that the server must send SILC_COMMAND_IDENTIFY
2799 command reply with error status to client who sent
2800 private message with invalid client ID.
2802 Updated the protocol specification.
2804 * Added silc_server_send_command_reply to send any
2805 command reply. Affected file silcd/packet_send.[ch].
2807 * Added silc_id_payload_encode_data to encode ID payload
2808 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2810 * The server now send IDENTIFY command reply with error
2811 status if client ID in private message is invalid. Affected
2812 file silcd/packet_receive.c.
2814 * Save the server key file with server's IP address in
2815 the filename instead of hostname. The affected file is
2816 irssi/src/silc/core/client_ops.c.
2818 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2823 * Added libtool support for compiling shared objects in
2824 lib/silcsim. Affected file configure.in.pre and
2825 lib/silcsim/Makefile.am. Original patch by cras.
2827 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Pid file configuration, and server's config file fixes
2830 patch by toma. Updated CREDITS file.
2832 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Fixed silc_client_channel_message to not try to decrypt
2835 the message twice if it resolved the destination client
2836 information. This could cause of dropping one channel
2837 message. Affected file lib/silcclient/client_channel.c.
2839 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2842 lib/silcclient/client.c. This function is used when the SILC
2843 Client is run under some other scheduler, or event loop or
2844 main loop. On GUI applications, for example this may be
2845 desired to used to run the client under the GUI application's
2846 main loop. Typically the GUI application would register an
2847 idle task that calls this function multiple times in a second
2848 to quickly process the SILC specific data.
2850 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2852 * Fixed silc_server_drop() for dropping the supplementary
2853 groups as well, this could cause a security hole on some
2856 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2861 * Write PID file after dropping privileges. Added -F option
2862 to run server on foreground. A patch by debolaz.
2863 Affected files silcd/server.c, silcd/silcd.c.
2865 * Fixed MOTD to return the MOTD file server name. Affected
2866 file silcd/command.c.
2868 * Added INFO command reply handling to the Irssi SILC Client.
2869 Affected file irssi/src/silc/core/client_ops.c.
2871 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Fixed the silc_idcache_list_* routines to really support
2874 the dynamic list. Fixes a crash. Affected file is
2875 lib/silccore/silcidcache.c.
2877 * Fixed the LIST command reply to really call LIST command's
2878 pending callbacks. Affected file silcd/command_reply.c.
2880 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Update conn->local_entry->nickname after giving NICK
2883 command. Affected file lib/silcclient/command.c.
2885 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2887 * Added the [pid] option to the silcd configuration file
2889 Affected files: serverconfig.[ch] and silcd.c
2891 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Save fingerprint in WHOIS command reply in server.
2894 Affected file silcd/command_reply.c.
2896 * Fixed NICK commands pending callback registration.
2897 Affected file lib/silcclient/command.c.
2899 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Use ++server->cmd_ident when sending commands in server,
2902 instead of random number. Affected file silcd/command.c.
2904 * Fixed GETKEY command reply to call actually GETKEY pending
2905 command callbacks. Affected file silcd/command_reply.c.
2907 * A bit stricter check for nicknames. Check for same nickname
2908 in NICK command also. Affected file silcd/command.c.
2910 * Do not call INFO command everytime client ID changes, only
2911 during first connecting. Affected file lib/silcclient/client.c.
2913 * Set the new nickname only after successful command reply for
2914 NICK command is returned by server. Affected file
2915 lib/silcclient/command.c.
2917 * Remove nicknames from nicklist during server_signoff notify.
2918 Should fix /NAMES bit more. The affected file is
2919 irssi/src/silc/core/silc-channels.c.
2921 * Added `fingerprint' field to the SilcIDListData in the
2922 silcd/idlist.h to hold the fingerprint of the client's
2925 Send the fingerprint of the client's public key in WHOIS
2928 Affected files silcd/command.c, and silcd/idlist.[ch].
2930 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2931 create fingerprint from given data.
2933 * Show the fingerprint of the client's public key in WHOIS.
2934 Affected files irssi/src/module-formats.[ch] and
2935 irssi/src/silc/core/client_ops.c.
2937 * Format the multiple same nicknames also during JOIN and
2938 NICK_CHANGE notifys. Affected file is
2939 lib/silcclient/client_notify.c.
2941 * Do not print error on screen for invalid private message
2942 payload since it can come if someone is sending private
2943 messages with wrong key. Affected file
2944 lib/silccore/silcprivate.c.
2946 * Fixed multiple concurrent /PING crash. Affected file
2947 lib/silcclient/command.c.
2949 * Changed the wrong ID encoding. All IP addresses must be
2950 in MSB first order in encoded format. They were encoded
2951 wrong and was in LSB format. Affected files are
2952 silcd/serverid.c, lib/silcutil/silcutil.c.
2954 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2956 * Call the `connect' client operation through the scheduler
2957 in case of error. Affected file lib/silcclient/client.c.
2959 * Call the `failure' client operation even if the error
2960 occurred locally during a protocol. Affected file is
2961 lib/silcclient/protocol.c.
2963 * Added support of sending LIST command to router from normal
2964 server. This way normal server can get list of all channels
2965 in the network too. Fixed the channel list sending in the
2966 server too. Affected files are silcd/command.c, and
2967 silcd/command_reply.[ch].
2969 * Added silc_server_update_channels_by_server and
2970 silc_server_remove_channels_by_server. They are used during
2971 disconnection of primary router and in backup router protocol.
2972 Affected file silcd/server_util.[ch], silcd/server.c and
2973 silcd/server_backup.c.
2975 * Fixed channel adding to global list in IDENTIFY command
2976 reply in server. Affected file silcd/command_reply.c.
2978 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * If the incoming packet type is REKEY or REKEY_DONE process
2981 that packet always synchronously. Fixes yet another MAC
2982 failed error on slow (dialup) connections. Affected file
2983 lib/silcclient/client.c and silcd/server.c.
2985 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Call check_version SKE callback for initiator too. Affected
2988 file lib/silcske/silcske.c.
2990 * Implemented fix for security hole found in the SKE that was
2991 fixed in the specification few days back; the initiator's
2992 public key is now added to the HASH value computation.
2993 Added backwards support for the old way of doing it too, for
2994 old clients and old servers. Affected file is
2995 lib/silcske/silcske.c.
2997 * Enabled mutual authentication by default in SKE. If initiator
2998 is not providing mutual authentication the responder will
2999 force it. This will provide the proof of posession of the
3000 private key for responder. The affected files are
3001 lib/silcclient/protocol.c and silcd/protocol.c.
3003 * Do not cache anymore the server's public key during SKE.
3004 We do mutual authentication so the proof of posession of
3005 private key is done, and if the server is authenticated in
3006 conn auth protocol with public key we must have the public
3007 key already. Affected file silcd/protocol.c.
3009 * Added new global debug variable: silc_debug_hexdump. If
3010 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3011 file lib/silcutil/silclog.[ch].
3013 * Fixed compilation warning due to char * -> const char *.
3014 Affected files lib/silcutil/silcnet.h, and
3015 lib/silccore/silcauth.[ch].
3017 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Fixed CMODE command when new channel key was created. If
3020 the creation failed the old key was removed. Next time giving
3021 same command would crash the server since the old key was
3022 freed already. Affected file silcd/command.c.
3024 * Fixed the silc_server_announce_get_channels to not crash
3025 on reconnect. Affected file silcd/server.c.
3027 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Added silc_log_set_debug_string function to set a regex
3030 string to match for debug output. Only the function names,
3031 or filenames matching the given debug string is actually
3032 printed. This way it is possible to filter out those debug
3033 strings that user is not interested in.
3035 Fixed a bug in silc_string_regexify.
3037 Affected files lib/silcutil/silclog.[ch], and
3038 lib/silcutil/unix/silcunixutil.c.
3040 * Changed the -d options in both server and Irssi SILC client
3041 to take the debug string as argument. Affected files
3042 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3044 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3046 * Added silc_hash_babbleprint to create a Bubble Babble
3047 Encoded fingerprint. The encoding is developed by Antti
3048 Huima (draft-huima-babble-01.txt), and it creates human
3049 readable strings out of binary data. Affected file
3050 lib/silccrypt/silchash.[ch].
3052 * Print the babble print now in addition of fingerprint as well
3053 in Irssi SILC client. Affected files are
3054 irssi/src/fe-common/silc/module-formats.[ch],
3055 irssi/src/fe-common/silc/core/client_ops.c.
3057 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Fixed a security problem found in SKE. The initiator's
3060 public key too is now added to the HASH hash value creation
3061 which is signed by the responder to create the SIGN value.
3062 This will prevent anyone in the middle to lie to the responder
3063 about the initiator's public key. If this is done now, the
3064 man in the middle will get caught. Updated the protocol
3067 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Better installation directory handling. Configure module
3070 paths and other paths automatically to example_silc* files
3071 in doc/. A patch by toma.
3073 * Fixed compiler warning from MPI library, and from SILC RNG.
3076 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3077 It can be configured with ./configure. A patch by toma.
3079 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Find correct make to use in prepare-clean. A patch by
3082 toma. Affected file prepare-clean.
3084 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3086 * Added irssi variables use_auto_addr, auto_bind_ip,
3087 auto_bind_port and auto_public_ip.
3089 * Changed the interface for silc_client_send_key_agreement
3090 in lib/silcclient/silcapi.h
3094 irssi/src/silc/core/silc-core.c
3096 lib/silcclient/silcapi.h
3097 irssi/src/silc/core/silc-channels.c
3098 lib/silcclient/client_keyagr.c
3101 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Added silc_pkcs_public_key_compare to compare two
3104 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3106 * Check that the client who set the founder mode on the
3107 channel is the same client that is giving the founder
3108 mode to itself. It is done by comparing the saved public
3109 key (it is saved even in the authentication is passphrase).
3110 Affected file silcd/command.c.
3112 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Do not process packet for disconnected socket connection.
3115 Affected file lib/silccore/silcpacket.c.
3117 * Process the DISCONNECT packet through scheduler in the
3118 client library. Affected file lib/silcclient/client.c.
3120 * Fixed the silc_client_packet_parse to not to increase
3121 the packet sequence number if the conn->sock and the
3122 current socket connection is not same. This can happen
3123 for example during key agreement when the conn includes
3124 multiple socket connections (listeners). Affected file
3125 lib/silcclient/client.c.
3127 * The sender of the file transfer request now provides also
3128 the pointer (listener) for the key exchange protocol. If
3129 the listener cannot be created then it sends empty key
3130 agreement and lets the receiver provide the listener.
3132 Added `local_ip' and `local_port' arguments to the
3133 silc_client_file_send. If they are provided they are used,
3134 if not then it will attempt to find local IP address, if
3135 not found or bind fails then the remote client will provide
3138 Affected files are lib/silcclient/client_ftp.c and
3139 lib/silcclient/silcapi.h.
3141 * Extended the FILE SEND command to support defining the
3142 local IP and port for key exchange listener. They are
3143 optional. Affected file irssi/src/silc/core/silc-servers.c.
3145 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Defined to WHOIS command reply the sending of fingerprint
3148 of the client's public key (if the proof of posession of the
3149 corresponding private key is verified by the server).
3150 Updated to the protocol specification.
3152 * Added support of receiving the client's public key's
3153 fingerprint in command reply in client library. Affected
3154 file is lib/silcclient/command_reply.c, and
3155 lib/silcclient/idlist.[ch].

3214 preserve the WHOWAS info for the client. Affected file
3215 silcd/server_util.c.
3217 * Fixed SERVER_SIGNOFF notify handling in the server. The
3218 server is now able to process incoming SERVER_SIGNOFF notify
3219 for a server that it doesn't even know about. It will remove
3220 the clients provided in the notify. Affected file
3221 silcd/packet_receive.c.
3223 * Check for partial packet in data queue after every packet that
3224 was found from the queue. Return and wait for more data if
3225 there is partial data in queue. Affected file is

3243 irssi/src/fe-common/silc/module-formats.[ch].
3245 * Wrote a help file for FILE command.
3247 * Added silc_rng_global_get_byte_fast to get not-so-secure
3248 random data as fast as possible. Random data is read from
3249 /dev/urandom if available and from the SILC RNG if not
3250 available. It is used in padding generation. Affected file
3251 lib/silccrypt/silcrng.[ch].
3253 * All packets in client library are now processed synchronously.
3254 Optimized packet processing a lot. Affected file
3255 lib/silcclient/client.c.

3266 * Assure that silc_client_notify_by_server_resolve does not
3267 resolve the client information multiple times. If it cannot
3268 be found by the first it cannot be found at all. Affected
3269 file lib/silcclient/client_notify.c.
3271 * Fixed WHOWAS command reply calling. Affected file
3272 lib/silcclient/command_reply.c.
3274 * Removed all references to silc_idlist_get_client from the
3275 Irssi SILC client since that call is internal call used by
3276 the library. The Irssi SILC client will use now client
3277 retrieval functions found in silcapi.h.
3279 * Fixed a bug in resolving nickname info before sending
3280 private message. It used freed memory. Affected file
3281 irssi/src/silc/core/silc-servers.c.

3302 * Added silc_net_localip to return local host's IP address.
3303 Affected file lib/silcutil/silcnet.[ch].
3305 * If key exchange or rekey protocol is active for a connection
3306 parse all packets syncronously since there might be packets
3307 in packet queue that we are not able to process without first
3308 processing packets before them. Affected file silcd/server,
3309 lib/silcclient/client.c.
3311 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3312 whether library should continue processing the packet.
3313 Affected file lib/silccore/silcpacket.h.

3359 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3360 is incomplete and is being resolved, it won't be resolved
3363 Make sure also that USERS command reply does not resolve
3364 twice information. Affected file is
3365 lib/silcclient/command_reply.c.
3367 Make sure that silc_client_get_clients_by_list does not
3368 resolve twice same information.
3370 * Check for valid client->id in the silc_server_free_client_data.
3371 Affected file silcd/server.c.
3373 * Fixed /GETKEY nick@server not to crash if the server entry
3374 is not found. Affected file lib/silcclient/command.c.
3376 * Fixed the silc_server_check_cmode_rights to check the

3384 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Call the silc_server_udpate_servers_by_server in the
3387 primary router that comes back online in the backup resuming
3388 protocol. Otherwise it routes packets wrong. Affected file
3389 silcd/server_util.[ch], silcd/server_backup.c.
3391 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3394 lib/silcutil/silcbuffmt.[ch].
3396 * Redefined the SILC packet header to include the padding
3397 length. Affected file lib/silccore/silcpacket.[ch].
3399 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3400 length for maximum padding up to 128 bytes). Affected
3401 file lib/silccore/silcpacket.h.
3403 * Removed all backwards support for old 0.5.x MAC thingies.
3404 The SILC packet header change makes it impossible to be
3405 backwards compatible.
3407 * Send the ENDING packet with timeout in the backup resuming
3408 protocol. This is to assure that all routers has connected
3409 to the primary router. Affected file silcd/server_backup.c.
3411 * Changed the RNG to take the first IV from random data. It
3412 used to take it from zero actually. Changed the RNG also
3413 to use /dev/urandom during session. /dev/random is used
3414 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3416 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Changed the SILC packet header to have the first two bytes
3419 (the packet length) encrypted. Affected files aroung the
3420 code tree, lib/silccore/silcpacket.[ch]. Removed the
3421 SilcPacketCheckDecrypt callback. It is not needed anymore
3422 since the silc_packet_receive_process will determine now
3423 whether the packet is normal or special.
3425 * Implemented the unidirectional MAC keys. Affected files
3426 lib/silcske/silcske.c, silcd/protocol.c and
3427 lib/silcclient/protocol.c.
3429 * Implemented the packet sequence number to the MAC computation.
3430 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3431 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3432 lib/silcclient/protocol.c.
3434 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Allow backup router to announce servers. All servers
3437 announced by backup router are added to the global list
3438 automatically. Update hte server's socket to our primary
3439 router also when backup router announces a server.
3440 Affected file silcd/packet_receive.c.
3442 * Do not update the client->router in the function
3443 silc_server_udpate_clients_by_server if the client is on
3444 global list. We might fail to find any specific server
3445 for locally connected clients and local cell clients. They
3446 should still use the `from' and not `to' as client->router.
3447 This fixes backup router resuming protocol. Affected file
3448 silcd/server_util.c.
3450 * Decrease channel statistics count only if the channel
3451 deletion worked. Affected files are silcd/server.c and
3452 silcd/server_util.c.
3454 * Added silc_server_update_servers_by_server to update origin
3455 of all server entries. Used during backup router protocol.
3456 Affected files silcd/server_util.[ch], silcd/server.c. and
3457 silcd/backup_router.c.
3459 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3460 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3461 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3462 lib/silccrypt/silchmac.c.
3464 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Assure that router cannot reroute the same channel message
3467 to the sender. Affected file silcd/packet_receive.c.
3469 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Made better checks that the channel message is not sent
3472 to the router it came from. Affected file is
3473 silcd/packet_send.c. Fixed memory leak too.
3475 * Announce informations for incoming router connection, but
3476 only after checking if it is replaced by backup router.
3477 Affected file silcd/packet_receive.c.
3479 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Fixed the backup resuming protocol to work in multiple
3482 router environment. Affected file silcd/server_backup.c.
3484 * Route packet only to one router in the function
3485 silc_server_packet_send_to_channel. Affected file is
3486 silcd/packet_send.c.
3488 * Fixed silc_server_send_notify_dest to set the broadcast
3489 flag. Fixed the silc_server_send_notify_topic to actually
3490 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3491 Affected file silcd/packet_send.c.
3493 * Changed the SFTP Filesystem interface. Changed the
3494 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3495 the filesystem operation function. The SilcSFTPFilesystem
3496 is now a context that is allocated by all filesystem allocation
3497 functions and it already includes the operations structure
3498 and filesystem specific context. It is given as argument
3499 now to the silc_sftp_server_start. This made the interface
3500 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3501 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3503 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Changed the backup router adding and getting interfaces
3506 in the server. The router that will be replaced by the
3507 specified backup router is now sent as argument. Affected
3508 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3511 * Added silc_net_addr2bin_ne to return the binary form of
3512 the IP address in network byte order. Affected files
3513 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3515 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Check for existing server ID in silc_server_new_server
3518 and in silc_server_connect_to_router_final and remove the
3519 old entry if it exists. Affected file silcd/packet_receive.c,
3522 * Send the channel message always to only one router, either
3523 in upstream or downstream. Affected file is
3524 silcd/packet_send.c.
3526 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Wrote the definition of the backup resuming protocol to the
3529 protocol specification.
3531 * Removed one redundant channel key generation from normal
3532 server during joining procedure. Removed one redundant
3533 channel key sending from server to router during joining
3534 procedure. Affected file silcd/command.c.
3536 * Made minor bugfixes to the backup router resuming protocol.
3537 Affected file silcd/server_backup.c, server.c.
3539 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Added --disable-asm configuration option. Affected files
3542 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3545 * Implemented the backup resuming protocol that is used to
3546 resume the primary router position in the cell after the
3547 primary router comes back online. Affected files
3548 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3549 and silcd/server_util.[ch].
3551 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Sleep two (2) seconds after sending QUIT command to server.
3554 Affected file lib/silcclient/command.c.
3556 * Assure that if outgoing data buffer is pending do not force
3557 send any data. Affected file silcd/packet_send.c.
3559 * Assure that if outgoing data buffer is pending do not force
3560 send any data. Affected file lib/silcclient/client.c.
3562 * Implemented the backup router support when the primary router
3563 goes down. The servers and routers can now use the backup
3564 router as new primary router without loosing connectivity.
3566 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3568 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3569 in the server to indicate disabled entry. All data read
3570 from the connection will be ignored and no data is sent
3571 for entry that is disabled. Affected files are
3572 silcd/idlist.h, silcd/server.c.
3574 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Created SFTP client and server test programs in the
3577 lib/silcsftp/tests directory.
3579 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Implemented memory filesystem (virtual filesystem) for
3582 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3585 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Implemented the SFTP (SSH File Transfer Protocol) to the
3588 lib/silcsftp. It includes SFTP client and SFTP server
3591 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Moved lib/silccore/silcprotocol.[ch] to the
3594 lib/silcutil library.
3596 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3597 take variable argument list pointer as argument. Affected
3598 file lib/silcutil/silcbuffmt.[ch].
3600 * Added silc_buffer_set function that is used to set data
3601 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3602 Affected file lib/silcutil/silcbuffer.h.
3604 * Changed various routines in the core library to use the new
3605 silc_buffer_set instead of allocating new buffer only for
3608 * Added 64-bit value formatting and unformatting support to the
3609 silc_buffer_[un]format routines. Affected file is
3610 lib/silcutil/silcbuffmt.[ch].
3612 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3613 to includes/bitmove.h.
3615 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * Fixed channel user mode saving in client library. Affected
3618 file lib/silcclient/command[_reply].c.
3620 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3622 * Defined the file transfer to the SILC Protocol. Added
3623 new packet type SILC_PACKET_FTP and defined File Transfer
3624 Payload. The mandatory file transfer protocol is SFTP
3625 (SSH File Transfer Protocol). Affected file in addition
3626 of the internet draft is lib/silccore/silcpacket.h.
3628 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3629 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3630 is used as part of backup router protocol when the primary
3631 router of the cell is back online and wishes to resume
3632 the position as primary router.
3634 * Redefined the MAC generation keys in the protocol. The
3635 same key is not used anymore in both direction. Both
3636 direction will now use different keys for sending and
3637 receiving. This fixes a potential security flaw. This
3638 change causes incompatibilities in the protocol.
3640 * Redefined also the MAC computation from the packet.
3641 An packet sequence number is now added to the MAC
3642 computation. This prevents possible replay attacks against
3643 the protocol. This change too causes incompatibilities
3646 Added `sequence' field to the SilcPacketContext to hold
3647 the current sequence number for the packet.
3649 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Added `created' field to the SilcIDListData in the file
3652 silcd/idlist.h to indicate the time when the entry was
3655 * Added `created' field to the SilcChannelEntry too. Affected
3656 file silcd/idlist.h.
3658 * Added `creation_time' aguments to all the announcement functions
3659 in the server. If it is provided then only the entries that
3660 was created after the provided time frame are actually
3661 announced. Affected file silcd/server.[ch].
3663 * The protocol says that the Channel ID's IP address must be
3664 based on the router's IP address. Added check for this in
3665 the silc_server_new_channel when processing incoming New Channel
3666 Payload. Affected file silcd/packet_receive.c.
3668 * Print out the correct version with --version in SILC client.
3669 Affected file irssi/src/silc/core/silc-core.c.
3671 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3673 * Fixed WHOWAS command to check for completnes of the client
3674 entry always, not just when the command is coming from client.
3675 Affected file silcd/command.c.
3677 * Added new function silc_server_packet_queue_purge to purge the
3678 outgoing data queue to the network. After the function returns
3679 it is guaranteed that the outgoing packet queue is empty.
3680 Affected file silcd/packet_send.[ch].
3682 * Purge the outgoing packet queue in the rekey protocol's final
3683 callback to assure that all rekey packets go to the network
3684 before quitting the protocol. Affected file silcd/server.c.
3686 * Added silc_client_packet_queue_parse as similar function as
3687 in server to the client library. The affected file is
3688 lib/silcclient/client.c.
3690 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * Splitted silcd/server.c and created silcd/server_util.[ch]
3693 for utility functions.
3695 * Added new socket flag SILC_SF_DISABLED to indicate that the
3696 connection is open but nothing can be sent to or received from
3697 the connection. Affected file lib/silcutil/silsockconn.[ch].
3698 The checking for disabled socket is checked in the low level
3699 silc_socket_write and silc_socket_read functions.
3701 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * Allow only nicknames and channel names that fits into the
3704 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3706 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * When processing JOIN command reply in server check that if
3709 the channel exists in our global list we'll move it the local
3710 list. Affected file silcd/command_reply.c.
3712 * Fixed the check whether client is joined on the channel already
3713 in JOIN command. Affected file lib/silcclient/command.c.
3715 * Fixed the JOIN command reply to check whether the channel
3716 already exists. Affected file lib/silcclient/command_reply.c.
3718 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Added silc_ske_status_string to map the SKE error numbers
3721 to readable strings. The affected files are
3722 lib/silcske/silcske[_status].[ch].
3724 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3726 * Do not show the private channels on the WHOIS channel list
3727 as it is not allowed by the protocol. The affected file is
3730 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Assure that the packet length digged from the actual packet
3733 is something sensible in the silc_packet_decrypt_rest_special
3734 in lib/silccrypt/silcpacket.c.
3736 * Free and NULL the allocated pointer in silc_hmac_alloc if
3737 the HMAC allocation fails. The affected file is
3738 lib/silccrypt/silchmac.c.
3740 * Print the selected security properties to the log files in
3741 the server. Affected file silcd/protocol.c.
3743 * Add SKE's reference counter even if calling the completion
3744 callback manually. Otherwise it goes negative, although it
3745 does not cause any problems. The affected file is
3746 lib/silcske/silcske.c.
3748 * Remove the client entry with short timeout after giving the
3749 KILL command. Affected file lib/silcclient/command.c.
3751 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3752 case all found clients are already disconnected (WHOWAS would
3753 found them) in the server. Affected file silcd/command.c.
3755 * Update the last_receive (time of last data received) to be
3756 updated only when received private or channel message so that
3757 the idle time showed in WHOIS makes more sense.
3759 * Added boolean field `valid' in to the SilcClientEntry in the
3760 client library to indicate whether the entry is valid or not.
3761 This fixes the nickname change bug on channel when changing
3762 the nickname to be same than the old (like nick to Nick) the
3763 nickname formatter doesn't set the new nick anymore to Nick@host.
3764 Affected file lib/silcclient/idlist.[ch].
3766 * Now actually fixed the nickname changing on disconnection.
3767 Added new function silc_change_nick to the Irssi SILC Client.
3768 Affected file irssi/src/silc/core/client_ops.c,
3769 irssi/src/silc/core/silc-nicklist.[ch].
3771 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3773 * Check that the public key exists in the GETKEY command before
3774 trying to encode it. Affected file silcd/command.c.
3776 * Print some notifications on received public keys with GETKEY
3777 command in the Irssi SILC Client. Affected files are
3778 irssi/src/fe-common/silc/module-formats.[ch],
3779 irssi/src/silc/core/client_ops.c.
3781 * Use IDENTIFY command to resolve the server information in the
3782 GETKEY command instead of INFO command. Affected file
3783 lib/silcclient/command.c.
3785 * All command reply functions in the client library now calls
3786 the pending command reply callbacks even if an error has
3787 occurred. The server has done this a long time and now it was
3788 time to move the client library to this as well. Now all
3789 errors can be delivered back to the pending command reply
3790 callbacks if necessary. Affected files are
3791 lib/silcclient/command[_reply].[ch].
3793 * Change the nickname on disconnection back to the username
3794 because in reconnect the server will enforce it to it anyway.
3795 Affected file irssi/src/silc/core/silc-servers.c.
3797 * Fixed a config file parsing bug in the Irssi SILC client.
3798 Affected file irssi/src/silc/core/clientconfig.c.
3800 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3802 * When printing the channel mode on JOIN, verify that the
3803 channel key and channel's HMAC are valid. Affected file
3804 irssi/src/silc/core/client_ops.c.
3806 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3808 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3809 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3810 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3812 * Removed channel key rekey task deleting from the function
3813 silc_server_save_channel_key. Affected file silcd/server.c.
3814 Added explicit timeout task context instead that is used to
3815 delete the task if we are registering a new task before the
3816 new task has elapsed.
3818 * When channel key rekey occurs the client library now saves
3819 the old channel key for a short period of time (10 seconds) and
3820 is able to use it in case some is still sending channel
3821 messages encrypted with the old key after the rekey. Affected
3822 file lib/silcclient/[idlist.h|client_channel.c].
3824 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3826 * Added check to the silc_server_new_id_real to not accept
3827 new ID if it is the sender's own ID. Affected file is
3828 silcd/packet_receive.c.
3830 * Assure that we do not announce ourself or the one we've
3831 sending our announcements when we're router and are announcing
3832 servers to our primary router. Affected file silcd/server.c.
3834 * Fixed silc_server_command_identify_check_client to assemble
3835 correct WHOIS packet. It send corrupted WHOIS packet and
3836 caused problem with router to router connections. Affected
3837 file silcd/command.c.
3839 Fixed also silc_server_command_whois_check the same way
3840 as for the IDENTIFY command.
3842 * Added new SilcIDListStatus to the server in the SilcIDListData
3843 structure. The status now includes the current status of
3844 the entry (like registered, resolved etc.). Affected file
3845 silcd/idlist.[ch]. Defined a bunch of different status types
3846 as well. This replaced the old boolean registered field as well.
3848 Added resolve_cmd_ident field to the SilcClientEntry structure
3849 too so that if the entry is for example being resolved so
3850 another command may attach to the same pending command reply
3851 without requiring to resolve the same entry again. This concept
3852 should optimize the WHOIS and the IDENTIFY resolving under
3853 heavy load by taking away unnecessary resolving for entries
3854 that are being resolved already.
3856 Added support for adding multiple pending commands for one
3857 command idenfier. Affected file silcd/command[_reply].[ch].
3859 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3860 before deleting the data. Otherwise the hash table will have
3861 freed data in comparison functions. Affected file is
3862 silcd/command_reply.c.
3864 * Fixed silc_idlist_replace_client_id to add the new entry to
3865 the cache with NULL nickname. Otherwise there will be invalid
3866 memory as the nickname after the nickname is freed. Affected
3867 file silcd/packet_receive.c.
3869 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3870 saved into wrong slots because the previous number of entries
3871 was not taken into account. Affected file silcd/idlist.c.
3872 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3874 * If we are router and we receive JOIN notify to a channel that
3875 does not have any users then notified client is marked as the
3876 channel founder, as it is it. The affected file is
3877 silcd/packet_receive.c
3879 * Added to the extended hash table API's table_del_*ext functions
3880 the destructor as argument too, so that the caller can decide
3881 which destructor to use or whether to use destructor at all.
3882 Affected file lib/silcutil/silchashtable.[ch].
3884 * Fixed ID Cache purging. It actually deleted the entries from
3885 the hash table after the data was freed. The hash table ended
3886 up comparing freed memory. The affected file is
3887 lib/silccore/silcidcache.c.
3889 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Fixed Irssi SILC client's KILL command's HELP syntax.
3893 * The USERS command now resolves the detailed user information
3894 if the userinfo field is missing. Affected file is
3895 lib/silcclient/command_reply.c.
3897 * Do not print error in silc_file_read if the read file does
3898 not exist. Just silently return NULL. Affected file is
3899 lib/silcutil/silcutil.c.
3901 * Fixed the silc_log_output to not wine about NULL filename
3902 and to not create some bogus " " filename. Affected file is
3903 lib/silcutil/silclog.c.
3905 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3907 * Fixed various printing bugs on the user interface in the
3908 Irssi SILC Client. Minor changes that were forgotten from
3911 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Fixed the configure.in.pre and the compilation and distribution
3914 environment to support the new autoconf 2.52. That version is
3915 now required to compile the CVS trunk.
3917 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3920 to generally parse user@fqdn format strings. Affected file
3921 lib/silcutil/silcutil.c.
3923 * Added nickname_format and nickname_force_format fields to the
3924 SilcClientParams structure. The first one defines the format
3925 for the nicknames that the library will enforce if the receives
3926 multiple same nicknames. The second one is boolean value and
3927 can be used to force the library to always enforce the format
3928 to the nicknames regardles whether there are multiple nicknames
3929 or not. This configurable formatting was employed to flexibly
3930 support accessing multiple nicknames from the user interface.
3931 The userinterface can now set the nicknames to what ever format
3932 they prefer. Affected file lib/silcclient/silcapi.h.
3934 Added function silc_client_nickname_format to the file
3935 lib/silcclient/idlist.c. It performs the nickname formatting.
3937 Added new field `hostname´ to the SilcClientEntry context.
3938 It holds the hostname of the client. Affected file is
3939 lib/silcclient/idlist.h.
3941 * Irssi SILC Client sets the nicknames in nick@hostn format.
3942 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3943 irssi/src/silc/core/silc-core.c.
3945 The WHOIS printing now also shows both the real nickname and
3946 the formatted nickname so that user knows how to access the
3947 user if there are multiple same nicknames cached. Affected
3948 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3949 printing formatting too to take the hostname now as a separate
3950 argument. The Affected file is
3951 irssi/src/fe-common/silc/modules-formats.[ch].
3953 * Changed the silc_client_get_clients_local to accept the formatted
3954 nickname as argument. It accepts the real nickname too but the
3955 formatted nickname can be used to find the true entry from
3956 multiple entries. Affected file lib/silcclient/silcapi.h and
3957 lib/silcclient/idlist.c.
3959 * Added nickname_format_parse field to the SilcClientParams.
3960 It is a callback function provided by the application to parse
3961 the nickname out of the formatted nickname string. The library
3962 calls it to get the nickname from the formatted string. Since
3963 the application generally knows better the format of the nickname
3964 string it parses it instead of the library, even though library
3965 encodes the formatted string. If the callback function is not
3966 provided then the library will use the string as is. The
3967 affected file is lib/silcclient/silcapi.h.
3969 * All the nickname strings passed to the client library in
3970 commands are now expected to be formatted nickname strings.
3971 If the command does not support the formatted nickname string
3972 it will assume that the sent string is the actual nickname.
3973 Affected file lib/silcclient/command.c.
3975 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3977 * Added public key authentication support to OPER and SILCOPER
3978 commands in the client library. Affected file is
3979 lib/silcclient/command.c.
3981 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3983 * Changed the get_auth_methdod client operation to be asynchronous.
3984 It can be async if the application resolves the authentication
3985 method from the server during the negotiation. Added new
3986 SilcGetAuthMeth completion callback that the application will
3987 call after resolving the authentication method.
3989 Added function silc_client_request_authentication_method that
3990 the application can use to resolve the authentication method
3991 from the server. Added also SilcConnectionAuthRequest callback
3992 that the library will call after the server has replied. The
3993 application can call this function if it does not know the
3994 current authentication method.
3996 Affected files are lib/silcclient/client.c and
3997 lib/silcclient/silcapi.h.
3999 * The Irssi SILC client now automatically resolves the authentication
4000 method incase any configuration information is not present (and
4001 currently there never is). The affected file is
4002 irssi/src/silc/core/client_ops.c.
4004 * Fixed public key authentication from the client library.
4005 Affected file lib/silcclient/protocol.c. Changed also the
4006 protocol specification about the public key authentication in
4007 the connection authentication protocol. The actual data to be
4008 signed is now computed with a hash function before signing.
4010 * Fixed the public key authentication from the server as well.
4011 Affected file silcd/protocol.c.
4013 * Removed the mlock()'s from the memory allocation routines.
4014 Affected file lib/silcutil/silcmemory.c. The ./configure does
4015 not check anymore for the mlock(). Affected file is
4018 * Fixed USERS command in server to allow the execution of the
4019 command for private and secret channels if the client sending
4020 the command is on the channel. Affected file silcd/command.c.
4022 * Fixed silc_client_get_clients_local to return the clients
4023 count correctly. It could return wrong value. Affected file
4024 lib/silcclient/idlist.c.
4026 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4029 types. The assembler optimizations seemed not to like 64-bit
4030 data types. The assmebler optimizations thus are now enabled
4031 also for BSD systems as opposed to only enable them for Linux.
4033 * Do not check for threads at all on BSD systems. Affected
4034 file configure.in.pre.
4036 * Removed -n and -h options from the Irssi SILC Client since
4037 they are not used in silc.
4039 * Fixed the prime generation to assure that the first digit
4040 of the generated random number is not zero since our conversion
4041 routines does not like number strings that starts with zero
4042 digit. If zero digit is seen the random number is regenerated.
4043 This caused some corrupted RSA keys when the zero first digit
4044 was met. Affected file lib/silcmath/silcprimegen.c.
4046 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * Fixed WIN32 configuration in the ./configure script.
4049 Fixed to include xti.h on environments that has it.
4050 Patches by Carsten Ilchmann and andrew.
4052 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Changed the silc_id_create_client_id to be collision
4055 resistant. It is now assured that there cannot be created
4056 two same client ID's. I suspect that some weird bugs in
4057 the server were actually caused by duplicate Client IDs.
4058 Affected file silcd/serverid.[ch]. A router receiving
4059 new ID now also assures and informs the sending server
4060 if the ID caused collision.
4062 * Changed the silc_id_create_channel_id to also assure that
4063 there are no collisions.
4065 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Statement about ignoring the Mutual Authentication flag when
4068 performing rekey with PFS was a bit misleading. It is ignored
4069 if it was set in the initial negotiation, it cannot be even
4070 set in the rekey. Fixed in the ke-auth draft. Started the
4071 new versions of the protocol drafts in the doc/.
4073 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4075 * Fixed a bug in silc_client_command_identify_save when saving
4076 new channel information. The channel name was no duplicated
4077 and caused crash on exit. Affected file is
4078 lib/silcclient/command_reply.c.
4080 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4082 * Fixed the getkey command handling in the server. Send just
4083 empty OK reply to the sender if the key could not be fetched
4084 (but everything else was ok, like the key just was not available).
4085 Changed the public key parameter to optional in the protocol
4086 specs so that empty OK reply can be sent. Affected file
4089 Added a message to Irssi SILC client to tell to user if the
4090 server did not return a public key.
4092 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4094 * Fixed a channel key regeneration bug. It registered new
4095 timeout tasks exponentially until all system resources were
4096 used. Affected file silcd/server.c.
4098 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4100 * Added the SILC Document generator to the scripts/silcdoc.
4101 It can be used to generate the Toolkit Reference Manual out
4102 of the source tree. Internally it will also use the RoboDoc
4103 generator now imported in util/robodoc.
4105 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4107 * Added couple of return's in rekey protocol if error orccurred
4108 during the protocol. The execution must be terminated.
4109 Affected file silcd/protocol.c. Also, terminate the protocol
4110 always with timeout.
4112 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4114 * The client's Client ID was created initally from the wrong
4115 nickname (it could have been in format nick@host) in the
4116 silc_server_new_client. Affected file silcd/packet_receive.c
4118 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4120 * Added some SILC_LOG_ERROR's to various error conditions
4121 if client could not be added to ID cache. Affected files
4122 silcd/packet_receive.c and silcd/server.c.
4124 * When client's sock->user_data is freed, NULL also the
4125 client->router and client->connection pointers. Added check
4126 for these pointers being NULL to various places around the
4127 code. Affected file silcd/server.c.
4129 * Added client->data.registered == TRUE checks to various
4130 places around the code to assure that unregistered client's
4131 are not handled when it is not allowed. Affected file
4134 * Added `bool registered' fields to all
4135 silc_idlist_[server|client]_get_* routines to indicate whether
4136 the fetched client needs to be registered or not. Affected
4137 file silcd/idlist.[ch].
4139 * Add your own entry as registered to the ID cache in the
4140 server. Affected file server.c.
4142 * Fixed a bug in silc_server_new_server. The SilcServer was
4143 set as the new server's context instead of SilcServerEntry.
4144 This naturally caused some weird bugs.
4146 * Added "updated" field the SilcChannelEntry which indicates
4147 the time since the channel entry was last accessed. This
4148 can be used to determine whether it is necessary to
4149 announce the channel after backup resuming protocol.
4150 Affected files silcd/idlist.[ch].
4152 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Do not delete the channel rekey task when adding it
4155 for in silc_server_create_channel_key.
4157 * Changed the silc_server_create_channel_key to return
4158 TRUE or FALSE to indicate the success of the channel key
4161 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Fixed MSVC++ project files and added missing files to
4164 Makefiles under win32/.
4166 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4168 * Do not add TCP_NODELAY flag if the operating system
4169 does not have it defined. Affected files are
4170 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4172 * Fixed buffer overflow from Irssi SILC Client. Affected
4173 file irssi/src/fe-common/core/themes.c.
4175 * Fixed double free in client library in the file
4176 lib/silcclient/client.c when disconnecting from server.
4178 * Applied double free patch from cras to Irssi SILC client.
4179 Affected files irssi/src/core/[modules/expandos].c
4181 * Fixed the disconnection handling to Irssi SILC Client.
4182 The application must call silc_client_close_connection
4183 in ops->connect client operation in case of failure of
4184 the connection. Affected file is
4185 irssi/src/silc/core/client_ops.c.
4187 * Do not set sock->protocol to NULL in the function
4188 silc_client_close_connection after executing the protocol's
4189 final callback since the sock might not be valid anymore.
4190 Affected file lib/silcclient/client.c.
4192 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Do not enable SILC_THREADS if the linking with libpthread
4195 did not happen. Affected file configure.in.pre.
4197 * Added notion to protocol specification that server must
4198 verify the sent authentication payload with CMODE when
4199 setting the channel founder key. Implemented it to the
4200 server. Affected file silcd/command.c.
4202 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4204 * Added _EXTRA_DIST SILC distribution variable to the
4205 distributions file. It is used to conditionally add extra
4206 files or directories to the specific distribution. Affected
4207 files ./prepare, Makefile.am.pre and distributions.
4209 Removed the `_' from the start of the distribution names.
4212 * Added README.WIN32 for instructions to compile the Toolkit
4215 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4217 * Fixed a double free in disconnection in the server. Affected
4218 file is silcd/server.c.
4220 * Fixed the lib/silcske/groups.c to work now also with GMP
4221 MP library. The string conversion did not work when using
4222 specific base and the base is indicated in the string as well.
4224 * Created win32/ directory which now includes MSVC++ specific
4225 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4226 It will appear only in the toolkit distribution
4228 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4230 * Changed the key material distribution function in case when
4231 the hash output is too short. The data is now concatenated
4232 a bit differently than it used to. Made the change to the
4233 SKE protocol specification.
4235 * Added better GMP detection to configure.in.pre. A patch
4238 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Fixed a minor bug in SKE that might cause some problem on
4241 some platforms. Affected file lib/silcske/silcske.c.
4243 * Added the cookie checking for initiator in the SKE. It checks
4244 that the responder returns the sent cookie unmodified. The
4245 affected file is lib/silcske/silcske.c. Added new SKE
4246 error type INVALID_COOKIE that can be sent during the
4247 negotiation. Fixed some memory leaks as well.
4249 * Added the "invalid cookie" error message to Irssi SILC client's
4252 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Added `task_max' field to the SilcClientParams to indicate
4255 the maximum tasks the scheduler can handle. If set to zero,
4256 default values are used. Affected file lib/silcclient/silcapi.h.
4258 * Fixed memory leaks in silc_client_close_connection. Affected
4259 file lib/silcclient/client.c.
4261 * Added silc_client_del_client_entry to client library to free
4262 all memory of given client entry. Affected file is
4263 lib/silcclient/idlist.[ch].
4265 * Added new functions silc_client_del_channel and
4266 silc_client_del_server to delete channel and server entries.
4267 Affected file lib/silcclient/[silcapi.h/idlist.c].
4269 * Removed silc_client_del_client_by_id from silcapi.h.
4271 * Fixed the INFO command to return the server's own info
4272 correctly when querying by Server ID. Affected file is
4275 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4277 * Removed the non-blocking settings in WIN32 code in the
4278 silc_sock_[read/write] and added SleepEx instead. Affected
4279 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4280 of input data is now checked with FIONREAD and ioctlsocket.
4282 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4284 * Call silc_schedule_task_del_by_context in the
4285 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4286 Affected file lib/silccore/silcprotocol.c.
4288 * Call silc_protocol_cancel for active protocols in the
4289 silc_server_close_connection if the funtion
4290 silc_server_free_sock_user_data has not been called.
4291 Affected file silcd/server.c.
4293 * Generic tasks cannot be deleted using the del_by_fd
4294 task deleting function since generic tasks does not match
4295 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4297 * Added a notion to SILCOPER help file that the SILCOPER works
4298 only on router server, not on normal server.
4300 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4302 * Added for WIN32 support for the new scheduler as well.
4303 Affected file lib/silcutil/win32/silcwin32schedule.c.
4305 * Fixed the SHA1 implementation to work on various platforms.
4307 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4310 API. It is part of the scheduler now. Everything else is
4311 as previously but some functions has changed their names.
4312 Checkout the lib/silcutil/silcschedule.h for the interface.
4313 Updated all applications to use the new interface. Affected
4314 files are lib/silcutil/silcschedule.[ch].
4316 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4318 * Found a bug in the SKE implementation. The HASH value,
4319 specified by the protocol, was not computed correctly. The
4320 public key of the responder was not added to the computation
4321 even though it is mandatory. Affected file lib/silcske/silcske.c.
4322 This unfortunately causes incompatibilities with older
4323 clients and servers.
4325 * Added WIN32 specific network init and uninit functions:
4326 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4327 the Winsock2. Affected file lib/silcutil/silcnet.h and
4328 lib/silcutil/win32/silcwin32net.c.
4330 * Set the socket always to nonblocking mode on WIN32 after
4331 reading data or writing data. Affected file is
4332 lib/silcutil/win32/silcwin32sockconn.c.
4334 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Fixed various compilation problems under WIN32. Affected
4337 files lib/silcutil/win32/silcwin32thread.c and
4338 lib/silcutil/win32/silcwin32schedule.c.
4340 * Removed all _internal.h #includes from public header
4341 files. Internal headers must never be included from
4344 Removed also the lib/silcske/payload_internal.h file.
4346 * All include files that may be needed (public and some others
4347 included by the public headers) by application developers are
4348 now copied to the ./includes directory. It does not copy any
4349 internal headers. Affected file Makefile.defines.pre and all
4350 Makefile.am's under lib/ and subdirs.
4352 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4354 * Do not change the ~/.silc directory's permissions automatically.
4355 Affected file irssi/src/silc/core/clientutil.c.
4357 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4359 * Do not cancel the protocol in silc_server_close_connection
4360 it might cause recursion. Now cancelled in the function
4361 silc_server_free_sock_user_data. Affected file silcd/server.c.
4363 * Fixed the silc_server_remove_clients_by_server to regenerate
4364 the channel keys correctly finally. Added also new function
4365 silc_server_remove_clients_channels to actually do it.
4366 Affected file silcd/server.c.
4368 * Fixed the silc_server_new_channel to not crash by giving
4369 wrong router to the new channel. Affected file is
4370 silcd/packet_receive.c.
4372 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4374 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4375 which is given as argument to the silc_client_alloc now.
4376 It can be used to configure the client and set various parameters
4377 that affect the function of the client.
4379 * The USERS command in server did not check whether the channel
4380 is private or secret. Affected file silcd/command.c.
4382 * Added new argument to the USERS command in protocol specification.
4383 The USERS command now can take the channel name as argument
4384 as well. Added support for this in client and server and
4385 updated the protocol specs.
4387 * Completed the GETKEY command in client. It can be now used
4388 to fetch also servers public key not only some clients.
4389 Affected files lib/silcclient/command[_reply].c.
4391 * Added silc_client_get_server to return server entry by the
4392 server name. Affected files lib/silcclient/silcapi.h and
4395 * Redefined the IDENTIFY command in protocol specification to be
4396 more generic. It now can be used to query information about
4397 any entity in the SILC Network, including clients, servers and
4398 channels. The query may be based either the entity's name
4399 or the ID. Added support for this in both client and server.
4401 Affected files silcd/command.c and lib/silcclient/command.c
4402 and command_reply.c.
4404 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4405 the _from_client and _from_server functions. Affected file
4408 * Added silc_client_get_channel_by_id_resolve to the file
4409 lib/silcclient/silcapi.h to resolve channel information by
4410 its ID. Added also silc_client_get_channel_by_id that
4411 does not resolve it from the server.
4413 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4415 * Added SilcServerEntry context into the client library
4416 to represent one server. The INFO command now allocates
4417 these to save the resolved server info. For now on the
4418 client library will also keep information about servers,
4419 connected and resolved with INFO.
4421 The INFO command now allocates the SilcServerEntry context
4422 and saves the server info there. The COMMAND_REPLY in
4423 the INFO now returns the parameters to application in
4424 same order as defined in the protocol specification.
4426 The entries are cached in the client->server_cache.
4428 * The INFO command is now issued after received the Client ID
4429 from the server. Affected file lib/silcclient/client.c.
4431 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4432 to the application as the mode changer might be server.
4433 It is guaranteed that NULL is not returned anymore to the
4434 application. Affected file lib/silcclient/client_notify.c.
4436 The ID Type is now also passed to the application so that
4437 it can check whether the returned entry is SilcClientEntry
4440 Added new function silc_client_get_server_by_id to return
4441 the server entry by ID. Affected files are the
4442 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4444 * Do not create the channel in the Irssi SILC Client when issuing
4445 the JOIN command but when received the sucessful JOIN command
4446 reply. Otherwise the channel might get created even though we
4447 could not join it. The Affected file is
4448 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4450 * Fixed a channel joining bug in router. The router must also
4451 check the channel modes, invite and ban lists etc. when serving
4452 the JOIN command sent by normal server. Affected file is
4453 silcd/command.c. The router now resolves the client's
4454 information from the server who sent the JOIN command if it
4455 does not know it, and processes the JOIN command only after
4458 * Changed the SilcCommandCb to take new argument; void *context2.
4459 Affected file lib/silccore/silccommand.h
4461 The second argument in the command callbacks in the server now
4462 includes the SilcServerCommandReplyContext if the command was
4463 called as pending command callback from the command reply.
4464 Otherwise it is NULL. When called as pending the status of the
4465 command reply will be checked and if it was erronous the
4466 error will be sent to the original sender of the command.
4467 This way the client always receives the error messages even
4468 though the server was actually the one who received the error
4469 when it resent the command to router, for example. Affected
4470 files silcd/command[_reply].[ch].
4472 * Fixed sending WHOWAS command's error message to client if
4473 the requested client could not be found. It was missing.
4476 * Changed the CMODE and CUMODE commands reply arguments in the
4477 protocol specification. The Channel ID is now sent in both
4478 of the commands to identify the channel. Implemented this
4479 new feature to the client and server. Affected files
4480 lib/silcclient/command_reply.c and silcd/command.c.
4482 * Made better checks for invite and ban lists in the JOIN
4483 command in server. Affected file silcd/command.c.
4485 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4487 * The server now performs the incoming host IP/DNS lookup
4488 using the silc_socket_host_lookup and thus does not block
4489 the server anymore. Affected file silcd/server.c.
4491 * Completed the multi-thread support for SILC Scheduler in
4492 the lib/silcutil/silcschedule.c.
4494 * Fixed the configure.in.pre to detect the pthread correctly
4497 * Fixed a deadlock in silc_task_queue_wakeup in the file
4498 lib/silcutil/silctask.c.
4500 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Added new function silc_schedule_wakeup that is used in
4503 multi-threaded environment to wakeup the main thread's
4504 schduler. It needs to be used when a thread adds a new task
4505 or removes a task from task queues. After waking up, the
4506 scheduler will detect the task queue changes. If threads
4507 support is not compiled in this function has no effect.
4508 Implemented the wakeup mechanism to both Unix and WIN32
4509 systems. Affected files are lib/silcutil/silcschedule.[ch],
4510 lib/silcutil/unix/silcunixschedule.c and the
4511 lib/silcutil/win32/silcwin32schedule.c.
4513 * Added new function silc_task_queue_wakeup to wakeup the
4514 scheduler by the specified task queue. Affected file
4515 lib/silcutil/silctask.[ch].
4517 * The silc_socket_host_lookup_start now wakes up the scheduler
4518 after adding the timeout task. Affected file is
4519 lib/silcutil/silcsockconn.c.
4521 * The silc_socket_host_lookup is synchronous now if the threads
4522 support is not compiled in. However, the callback is still
4523 called asyncronously through the scheduler, anyway. Affected
4524 file lib/silcutil/silcsockconn.c.
4526 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4528 * Added new function silc_socket_host_lookup to perform
4529 asynchronous IP and FQDN lookups for the socket connection.
4530 Affected files lib/silcutil/silcsockconn.[ch].
4532 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4534 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4535 that may or may not compile the mutex support in.
4537 Changed the silc_mutex_alloc interface. It allocates the
4538 mutex now to the sent pointer and returns TRUE or FALSE.
4540 Affected file lib/silcutil/silcmutex.h.
4542 * Wrote the SILC Task Queue interface to support multi-threads.
4543 Affected file lib/silcutil/silctask.[ch].
4545 * Wrote the SILC Scheduler to support multi-threads. Affected
4546 file lib/silcutil/silcschedule.c.
4548 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4550 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4551 in lib/silcutil/win32/.
4553 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4555 * Defined SILC Mutex API and SILC Thread API and implemented
4556 them for Unix. Affected files are
4557 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4558 lib/silcutil/unix/silcunixmutex.c and
4559 lib/silcutil/unix/silcunixthread.c.
4561 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4563 * Fixed the silc_server_remove_clients_by_server's channel
4564 key re-generation. The hash table handling was incorrect
4565 and would not work with many channels. Affected file is
4568 * Fixed some memory leaks around the server code.
4570 * Rewrote the silc_server_get_users_on_channel to support IPv6
4571 based Client ID's. Affected file silcd/server.c.
4573 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4574 specification. However, a separate document must be written
4575 to define the detailed signing procedure and the payload
4576 associated with the flag. Defined the flag to the
4577 lib/silccore/silcchannel.h as well.
4579 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4581 * Changed the dynamic tables to static size tables in the
4582 lib/silccrypt/silchmac.c.
4584 * Removed GCC dependencies from the code. A patch by cras.
4586 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4588 * Do not show the error "Error receiving packet bla bla"
4589 in server if it really was not an error (-2 means that reading
4590 is pending). Affected file silcd/server.c.
4592 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4594 * Fixed a possible crash in silc_server_remove_clients_by_server
4595 in silcd/server.c. Fixed there also some memory leaks.
4597 * Fixed the silc_idlist_replace_client_id. It could replace
4598 wrong key in the hash table. Affected file silcd/idlist.c.
4600 * Do not check whether there are global users on the channel
4601 if the channel->global_users is FALSE. Affected functions
4602 silc_server_remove_from_one_channel and
4603 silc_server_remove_from_channels in silcd/server.c. Also,
4604 do not check if the removed client is local as we can be
4605 sure that global client was not removed from the channel
4606 and checking for global users is not needed.
4608 * The silc_server_remove_clients_by_server now re-generates
4609 the channel keys correctly for those channels that had
4610 clients removed from them. Affected file silcd/server.c.
4612 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4614 * Found the reason of random crashes in the server. We weren't
4615 ignoring the SIGPIPE signal (which can be sent in write())
4616 and it crashed the server. Affected file silcd/silcd.c.
4618 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4620 * Assure that sock->user_data is not NULL in the function
4621 silc_server_packet_send in silcd/packet_send.c.
4623 * Disconnect the remote connection if it could not be added
4624 to any ID lists in the server. The affected file is
4627 * Check in silc_server_packet_send[_real/dest] that the
4628 socket is not disconnecting and ignore the data if it is.
4629 Affected file silcd/packet_send.c.
4631 * Define inline to __inline on native WIN32 compilation.
4632 Affected file includes/silcwin32.h.
4634 * Added some explicit type casts for inline code since MSVC
4635 require them. Affected files lib/silcutil/silcbuffer.h,
4636 lib/trq/silcdlist.h and lib/trq/silclist.h.
4638 * Print warning in log files from now on if the packet
4639 decryption fails. Affected file silcd/server.c.
4641 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4643 * Changed the `say' client operation's interface to accept
4644 new `type' argument to indicate the type of the message sent
4645 by the library. The application may filter the library's
4646 messages according the type. The affected file is the
4647 lib/silcclient/silcapi.h.
4649 * Added two new functions to lib/silcclient/silcapi.h:
4650 silc_client_del_client and silc_client_del_client_by_id.
4651 Affected file lib/silcclient/idlist.c.
4653 * Moved the clientincludes.h from includes/ to silc/ and
4654 serverincludes.h from includes/ to silcd/.
4656 * The modes for the CMODE and CUMODE are now passed as
4657 uint32 for application with COMMAND_REPLY. The affected
4658 file is lib/silcclient/command_reply.c.
4660 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4662 * /WHOIS without arguments shows client's own information.
4663 Affected file lib/silcclient/command.c.
4665 * Changed PING to not accept any arguments. The specs
4666 says that client can ping only the connected server so
4667 requiring an argument is not needed. Affected file is
4668 lib/silcclient/command.c.
4670 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4672 * Fixed a fatal bug in private message sending and reception
4673 encryption and decryption when using private message keys.
4674 The implementation was incorrect and did not follow the
4675 specification. It causd that some of the message were
4676 lost since it did not use the sending and receiving keys
4677 as the protocol suggests. This has been fixed and will cause
4678 incompatibilities with older clients when sending private
4679 message encrypted with private message keys. Affected files
4680 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4681 and various other in Irssi SILC Client.
4683 Added `responder' boolean argument to the functions
4684 silc_client_add_private_message_key[_ske] to indicate when
4685 the key is added as responder or initiator of the key
4688 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4690 * Removed the silc_ske_check_version function and created
4691 a SilcSKECheckVersion callback. Added also a function
4692 silc_ske_set_callbacks that is now used to set all SKE
4693 callbacks. The callback functions are not given to
4694 the SKE functions anymore, but this function is used to
4697 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4699 * Added `silc_version' argument to the silc_client_alloc
4700 to define the version of the application for the library.
4701 The library will use the version string to compare it
4702 against the remote host's (usually a server) version
4703 string. Affected file lib/silcclient/silcapi.h
4705 * Added the KE protocol context to Key Agreement context
4706 in client library so that we can abort the SKE if it
4707 is in process when we get timeout. Affected file is
4708 lib/silcclient/client_keyagr.c.
4710 * Do not resolve the client ID forever if it returns in the
4711 first time that such client does not exist. This was done
4712 for example with private message. Affected file is
4713 lib/silcclient/client_prvmsg.c.
4715 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4717 * Do not add regex.h for WIN32. The affected file
4718 includes/silcincludes.h.
4720 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4721 not work yet 100%. It generates the DLL's automatically
4722 when compiling with --with-win32 under cygwin.
4724 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4726 * lib/contrib/regex.c is not compiled on WIN32.
4728 * Added silc_net_get_socket_opt function to the
4729 lib/silcutil/silcnet.h.
4731 * Added includes/silcwin32.h for WIN32 specific includes
4734 * Do not use ptime structure or any of the posix process
4735 functions on WIN32 in lib/silccrypt/silrng.c.
4737 * Added silc_gettimeofday to provide generic function
4738 for struct timeval on all platforms. Added the function
4739 to lib/silcutil/silcutil.h.
4741 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4743 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4744 library as they clearly belong there. As a plus side we
4745 can make the actual socket connection routines platform
4748 Added also new generic function silc_socket_read and
4749 silc_socket_write (that used to be silc_packet_[read/write].
4750 The implementation of these are platform specific.
4752 * Added WIN32 specific routines of silc_socket_[read/write]
4753 to lib/silcutil/win32/silcwin32sockconn.c.
4755 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4757 * Added preliminary support for native WIN32 compilation under
4758 cygwin (using the -mno-cygwin option for GCC) to the
4759 ./configure.in.pre. The --with-win32 now prepares the
4760 compilation for native WIN32.
4762 * Rewrote the SILC Scheduler interface in the file
4763 lib/silcutil/silcschedule.h. The scheduler is now context
4764 based and does not have anymore any global static scheduler.
4765 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4766 and created lib/silcutil/win32 directory for WIN32 based
4769 * Added Unix specific network routines to the
4770 lib/silcutil/unix/silcunixnet.c and the old
4771 lib/silcutil/silcnet.c includes now only generic routines.
4773 Added WIN32 specific network routines to the
4774 lib/silcutil/win32/silcwin32net.c.
4776 * Added Unix specific utility functions from the
4777 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4779 * Added WIN32 SILC Scheduler to the file
4780 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4783 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4785 * Do not handle JOIN notify in the server if the target client
4786 is not registered (idata->registered == FALSE). The affected
4787 file is silcd/packet_receive.c.
4789 * Update the nickrec->founder in event_cumode in the Irssi SILC
4790 client. Affected file irssi/src/silc/core/silc-channels.c.
4792 * Fixed the CUMODE_CHANGE notify handling in the server when
4793 server and router are announcing their clients on channels.
4794 Now the mode changes are saved and notified correctly. The
4795 affected file is /silcd/packet_receive.c.
4797 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4798 They really did not replace the cache entry in the ID Cache.
4799 Now they do that. Affected file silcd/idlist.c.
4801 * Fixed the KICK notify handling in the Irssi SILC client to
4802 update the channel records so that the kicked client does not
4803 appear to be on the channel. The affected file is
4804 irssi/src/silc/core/silc-channels.c.
4806 * Always update the conn->current_channel when executing command
4807 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4809 * Fixed the KILL notify handling in Irssi SILC client to remove
4810 the killed client on all channels.
4812 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Fixed the silc_parse_command_line to remove extra spaces
4815 from the start and end of the arguments. Affected file is
4816 lib/silcutil/silcutil.c.
4818 * Cancel and free any active protocol in the function
4819 silc_server_close_connection. Affected file silcd/server.c.
4821 * Cancel and free any active protocol in the function
4822 silc_client_close_connction. Affected file is
4823 lib/silcclient/client.c.
4825 * Do not execute the KILL command for clients that are in
4826 history (ie. they are not in the network). Affected file is
4829 * Fixed KILL notify handling, client does not crash anymore.
4830 Affected file irssi/src/silc/core/silc-channels.c.
4832 * Reduced the default packet buffer size from 2048 to 1024 in
4833 lib/silccore/silcpacket.c.
4835 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4836 counter to the SKE context that is incresed when the SKE library
4837 performs async operation outside the library. If the outside
4838 process frees the SKE context and FREED status will be set
4839 and the library will detect after the sync operation that the
4840 libary is freed. The affected files are
4841 lib/silcske/silcske[_status].[ch].
4843 * Resolve the client entry information in the function
4844 silc_client_channel_message to assure that NULL pointer is not
4845 passed as client entry to the application. */
4847 * Fixed the task timeout calculation to assure that there is
4848 never negative timeouts. The affected file is
4849 lib/silcutil/silcschedule.c.
4851 * Fixed the channel user mode notification sending in server.
4852 It was sent point-to-point to the router (or to server by router)
4853 but it needs to be destined to a channel. The routines now
4854 supports sending the channel user mode notifys to the channels
4855 when announcing clients and channels. Affected files are
4856 silcd/server.c and silcd/packet_receive.c.
4858 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4859 It did not actually replace the old channel entry in the cache.
4860 Affected file lib/silcclient/client_notify.c.
4862 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Fixed a possible crash in silc_packet_send_prepare. It now
4865 assures always that there is enough space in the buffer and
4866 at the tail area of the buffer (for MAC).
4868 Fixed the inbound buffer reallocation in silc_packet_read.
4869 It was old code and did not handle the reallocation correctly.
4872 The affected file is lib/silccore/silcpacket.c.
4874 * Fixed buffer overflow in silc_parse_nickname in the file
4875 lib/silcutil/silcutil.c.
4877 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * make install generates new server keys only if there is not
4882 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4885 Added check that if the NOREPLY is set then we will not send
4886 the away message. This avoids infinite loop of away messages
4887 if both clients are away. The affected file is
4888 lib/silcclient/client_prvmsg.c.
4890 * Fixed client crash if /NICK was given without arguments.
4891 Affected file lib/silcclient/command.c.
4893 * Server does not send the invite list in INVITE command back
4894 to the client if the list was not altered. Added this notion
4895 to the protocol spec as well. Affected file silcd/command.c.
4897 Fixed possible crash in INVITE command by checking the
4898 value of silc_server_get_client_route command.
4900 * Fixed the INVITE notify type handling. The arguments are now
4901 taken in correct order and client does not crash. The affected
4902 file is irssi/src/silc/core/silc-channels.c.
4904 Removed the "Inviting xxx to channel" message from the
4905 client library away and let the application handle it.
4906 Affected file lib/silcclient/command.c. Added that message
4907 to Irssi SILC client's message formats.
4909 * Fixed CMODE command crash in client. It now checks the
4910 amount of arguments correctly and does not crash. The affected
4911 file is lib/silcclient/command.c.
4913 * Do not create new channel automatically in silc_channels_join
4914 but check whether the channel by that name already exists.
4915 Affected file irssi/silc/core/silc-channels.c.
4917 * Do not send the SERVER_SIGNOFF to router if the disconnected
4918 entity was the router. Affected file silcd/server.c.
4920 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4921 SILC client as it was missing from there.
4923 Added the handling of the KICK notify to the Irssi SILC client
4924 as it was missing. Added "you have been kicked" message to
4925 Irssi SILC client's message modules formats.
4927 Added the handing of the KILL notify to the Irssi SILC client
4928 as it was missing. Added the kill message module formats
4931 The affected file is irssi/src/silc/core/silc-channels.c.
4933 * The router did not save the channel mode the server announced.
4934 Affected file silcd/packet_receive.c.
4936 * Fixed a possible crash in INFO command in server. If the
4937 server did not provide the server info it crashed. Affected
4938 file silcd/command.c.
4940 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Fixed the GETKEY command in the server to check also the
4943 global list. Otherwise the GETKEY would not work correctly
4944 in normal SILC server. Affected file silcd/command.c.
4946 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Fixed GETKEY crash, it crashed if the command did not succseed.
4950 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4953 is now real and not just an macro interface to GMP.
4955 Removed the entire GMP from the source tree and imported new
4956 NSS MPI library instead. Reason for removing GMP is that it is
4957 extremely large and compiles extremely slow. The NSS MPI
4958 is only a few files and compiles in less than 10 seconds.
4959 The speed is also about the same as GMP. The MPI is imported
4960 to lib/silcmath/mpi.
4962 If the system has GMP installed we will still use the GMP.
4963 If it is not then the NSS MPI will be compiled.
4965 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Merged a long nickname (127 characters long) crash bugfix from
4968 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4970 * Merged a freed memory reference bugfix from Irssi CVS tree.
4971 Affected file irssi/src/core/commands.c.
4973 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Added the server's public key sving and verification to the
4976 server when performing the SKE. This was missing and the
4977 remote server's (or router's) public key was accepted without
4978 checking whether we have it previously or trust it at all.
4979 Affected file silcd/protocol.c.
4981 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Check in the silc_server_timeout_remote if protocol is active
4984 and make sure that the protocol's final callback is called so
4985 that all memory if freed. Affected file silcd/server.c.
4987 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * silc_server_whois_send_reply crashed the server if the nickname
4990 was 127 characters long. Affected file silcd/command.c.
4992 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Added sanity check to the silc_server_new_client. If the hostname
4995 is provided inside username then check that the provided hostname
4996 really is the same as the resolved one. If the hostname was not
4997 resolved then check it from the public key. Affected file is
4998 silcd/packet_receive.c.
5000 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5001 if the server disconnected us and the connection is not valid
5002 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5004 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5005 the library to the lib/silcutil/silcutil.[ch].
5007 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Close log file after open. Affected file
5010 lib/silcutil/silclog.c.
5012 * Check whether sock == NULL in silc_client_send_packet and return
5013 if it is. Affected file lib/silcclient/silcclient.c.
5015 * Check rec->entry == NULL in the Irssi SILC Client before
5016 sending the channel message. Affecte file is
5017 irssi/src/silc/core/silc-servers.c.
5019 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Merged a splitted window bugfix from Irssi CVS tree. The
5022 affected file is irssi/src/fe-text/textbuffer-view.c.
5024 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5025 It did not print nickname.
5027 * Improved the distributions system a bit.
5029 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5032 irssi/src/fe-text/gui-window.c.
5034 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5035 to in-active server. The affected file is
5036 irssi/src/silc/core/client_ops.c.
5038 * Resolve the client in USERS command reply if the entry does
5039 not have username resolved. The affected file is
5040 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5041 command to WHOIS command to really resolve stuff. The USERS
5042 is not used any more in any critical section so WHOIS can
5043 be used even though it might be slower than IDENTIFY.
5045 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5048 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Changed the protocol API a bit more consistent in the
5051 lib/silccore/silcprotocol.[ch].
5053 * Changed the following headers to ROBODoc format:
5055 lib/silccore/silcpayload.h
5056 lib/silccore/silcprotocol.h
5057 lib/silccore/silcsockconn.h
5059 All core library headers are now formatted.
5061 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Fixed a bug in Irssi SILC client; do not show that you are
5064 server/router operator if you really are not. Affected file is
5065 irssi/src/silc/core/client_ops.c.
5067 * Renamed silc_command_free_payload to silc_command_payload_free.
5068 Affected file lib/silccore/silccommand.h
5070 * Added silcmath.h to include the prototoypes of various routines
5071 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5074 * Changed the following headers to ROBODoc format:
5076 lib/silccore/silcchannel.h
5077 lib/silccore/silccommand.h
5078 lib/silccore/silcid.h
5079 lib/silccore/silcidcache.h
5080 lib/silccore/silcmode.h
5081 lib/silccore/silcnotify.h
5082 lib/silccore/silcpacket.h
5083 lib/silcmath/silcmath.h
5085 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added checking to the server code not to start the server if
5088 ciphers and stuff are not configured properly. Affected files
5089 silcd/serverconfig.[h] and silcd/server.c.
5091 * Changed the layout of the header files of the public interfaces
5092 in the SILC libraries. The new layout supports ROBODoc
5093 documentation tool (and some others) so that it is easy to create
5094 a library reference manual. All the other headers and source
5095 code must still follow the CodingStyle document. Also source
5096 code must not include these ROBODoc stuffs, only the headers.
5097 Furthermore, all public interface headers must now be named
5098 by using `silc' prefix, example: silcapi.h, silccipher.h.
5099 Some files were renamed due to this. All the other headers
5100 must not be used as public interfaces. I will update the
5101 CodingStyle document later. Changed following headers, so far:
5103 lib/silcclient/silcapi.h
5104 lib/silccore/silcauth.h
5105 lib/silccore/silcprivate.h
5106 lib/silccrypt/silcdh.h
5108 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Removed silc_client_packet_send_flush from the client library
5113 as it is not needed. Affected file lib/silcclient/client.[ch].
5115 * Added printing of message of unresolved authentication method
5116 to the Irssi SILC client. Added it to the module formats.
5117 Removed the same message from the client library.
5119 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Added new distribution feature, DISTLABEL. Every distribution
5122 can define own preprocessor label that can be used in the
5123 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5124 file distributions, acconfig.h.pre and prepare.
5126 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added Makefile.defines_int to include the actual definitions
5129 for Makefile.defines.in. Tested the new distribution system,
5130 created distributions and tested installation.
5132 * Added AWAY message printing to the Irssi SILC client. Added
5133 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5135 * Added SCONNECT command to call the SILC's CONNECT command.
5136 Cannot use CONNECT directly since Irssi uses that internally.
5137 Affected file irssi/src/silc/core/silc-servers.c.
5139 Added ACTION local command. It is same as ME command but takes
5140 the channel as mandatory argument.
5142 Rewrote some of the Irssi's help files to suite for SILC
5145 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Added Makefile.defines[.in] that should for now on be included
5148 in all Makefile.am file in the source tree. That file includes
5149 all common compilation definitions for SILC source tree.
5151 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Minor changes to the ./prepare script to change the package
5154 name according the distribution name to the configure.in.
5156 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Created new distribution system. Added file `distributions'
5159 that defines all the distributions that can be created out of
5160 the SILC source tree. The ./prepare script now reads that
5161 file to determine how to prepare the distributions. The
5162 first argument to the ./prepare is the name of the distribution
5163 and second is the version of the distribution. If given
5164 without arguments it creates the default (toolkit) distribution
5165 with the default version (defined in ./prepare).
5167 All Makefile.am files that are subject to the distributions
5168 are now named as Makefile.am.pre. These are ./Makefile.am
5169 and lib/Makefile.am. Others may be changed later.
5171 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added invite list, ban list, some key management and connection
5174 error message printing to module formats in the Irssi SILC client.
5176 * Added new silc_client_set_away_message to set the away message
5177 that is back to the person who sent private message. The
5178 affected file lib/silcclient/silcapi.h and the
5179 lib/silcclient/client_prvmsg.c.
5181 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Fixed the private message sending in the Irssi SILC client,
5184 added local command KEY to the Irssi SILC client.
5186 Added key management and key agreement message formats to the
5187 irssi/src/fe-common/silc/module-formats.[ch].
5189 Added USERS (alias WHO) printing, server/router operator
5190 indication and LIST command printing to the module formats.
5192 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5194 * Fixed channel joining notify handling, cumode notify handling
5195 from Irssi SILC client.
5197 * Added SILC specific module-formats to the Irssi SILC client so
5198 that SILC specific message hilighting, colors etc is possible.
5199 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5201 Added channel mode, channel user mode, actions, notices,
5202 whois and whowas printing to the the module-formats.c.
5204 * Fixed a bug in channel deletion in the server. The channel
5205 is not left to the cache even if the channel founder auth mode
5206 is set when there are no users anymore on the channel. Affected
5207 file silcd/server.c.
5209 * The silc_net_localhost now resolves the entire hostname including
5210 the domain name. Affected file lib/silcutil/silcnet.c.
5212 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Changed the ask_passphrase client operation to be ascynchronous.
5215 It has now a completion callback and a context that the
5216 application must call after it has got the passphrase from
5217 the user. Affected files lib/silcclient/silcapi.h,
5218 lib/silcclient/protocol.c, lib/silcclient/command.c and
5221 Added SilcAskPassphrase callback that the application calls
5222 to deliver the passphrase to the library.
5224 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5225 The public key verification and especially a certificate
5226 verification is asynchronous procedure.
5228 Added new SILC_SKE_STATUS_PENDING status to indicate the
5229 request is pending and a callback will be called to finalize
5232 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5233 indicate that remote end did not send its public key (or
5234 certificate), even though we require it. Added check for this
5235 condition in the SKE. This was a security bug, now fixed.
5237 Defined new SilcSKEVerifyCbCompletion callback that is called
5238 when the verification process is completed.
5240 The affected files lib/silcske/silcske_status.h and
5241 lib/silcske/silcske.[ch].
5243 * Changed the verify_public_key client operation to be async
5244 as well. Defined SilcVerifyPublicKey callback that is used to
5245 indicate the success of the public key verification process.
5247 Changed the server and client to use the new async client
5250 * Changed the Irssi SILC client's internal scheduler to be called
5251 twice as many times as it used to be. As a result the client
5252 should be a bit faster now. Affected file is
5253 irssi/src/silc/core/silc-core.c.
5255 * Added support to Irssi SILC client of asynchronous public key
5256 verification and passphrase inquiry. Affected file is
5257 irssi/src/silc/core/silc-core.c.
5259 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Do not say "You have left channel %s" in client library.
5262 Moved it to the application. Affected files are
5263 lib/silcclient/command.c and silc/client_ops.c.
5265 * Fixed silc_client_get_clients. Command context was not
5266 duplicated and was freed memory in the callback. Affected
5267 file lib/silcclient/idlist.c.
5269 * Do not say "you are now talking..." on JOIN command in the
5270 client library. The appliation must handle it.
5272 * Do not say ".. changed topic to" in command reply in the
5273 client libary. The application must handle it.
5275 * Fixed TOPIC command sending in the client library.
5277 * Fixed a memory leak in silc_client_command_free in the file
5278 lib/silcclient/command.c.
5280 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Imported a modified version of Irssi client to the source tree.
5283 The Irssi will be used to create a new client called
5284 Irssi SILC. Imported to irssi/.
5286 Added silc_core_init_finish function to the Irssi. Affected
5287 file irssi/configure.in.
5289 A lot changes in the Makefile.ams around the irssi tree.
5291 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Do not rehash if the new size is same as the old size of the
5294 hash table, in the silc_hash_table_rehash*. The affected file
5295 lib/silcutil/silchashtable.c.
5297 * Replaced hash_table_del_by_context calls from the server
5298 (when channel->user_list and client->channels) to the
5299 hash_table_del as it is sufficient and faster.
5301 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added silc_hash_table_list, silc_hash_table_get and the
5304 SilcHashTableList structure to provide an alternative way to
5305 traverse the hash table. The affected files are
5306 lib/silcutil/silchashtable.[ch].
5308 * Changed the server's idlist routines to use the hash table
5309 routines to optimize the code.
5311 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Replaced the client entry's `channel' list and channel entry's
5314 `user_list' list to hash tables for optimized lookup. Changed
5315 the code to use the hash table interface around the code.
5316 Affected file lib/silcd/idlist.[ch].
5318 * Added `auto_rehash' boolean argument to the function
5319 silc_hash_table_alloc to indicate whether the hash table should
5320 auto-rehash when it thinks is appropriate time. It will
5321 increase the hash table size if the there is twice as much
5322 entries in the table than the size of the table, and will
5323 decrease the size if there are twice as less entries than
5324 the size of the table.
5326 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5330 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * silc_idcache_purge_by_context deletes the entry now by context
5333 as it is supposed to do. Affected file lib/silccore/idcache.c.
5335 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5336 client is not anymore valid (WHOWAS givens the info) and not
5337 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5339 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Removed the `data' and `data_len' arguments from the ID Cache
5342 interfaces and added `name' argument. ID Cache does not handle
5343 anymore the binary data only a names associated with given ID.
5345 * When hashing a Client ID with silc_hash_id the entire ID is
5346 not hashed anymore, instead only the hash of the Client ID is
5347 hashed. This way we can access the Client ID from the cache
5348 with Client ID but with the hash of the ID (which is a hash of
5349 the nickname) as well without any difference in performance.
5351 Added also silc_idcache_find_by_id_one_ext to do one on one
5352 searching when we have the actual ID. Added also function
5353 silc_hash_client_id_compare. The affected files are
5354 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5356 * When hashing the name associated with a ID it is always done
5357 in lowercase. This way we can access the cache without worrying
5358 about case-sensitivity, even though, for example nicknames are
5361 * Fixed a bug in server with channel message sending. It put
5362 wrong ID type as destination ID. The affected file
5363 silcd/packet_send.c.
5365 * silc_idcache_del_by_context now deletes from all hash tables
5366 by context. Affected file lib/silccore/idcache.c.
5368 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Changed the client library to use the new ID Cache interface.
5371 Changes around the source tree.
5373 * Added silc_hash_table_rehash_ext to rehash with specific
5374 hash function. Affected file lib/silcutil/silchashtable.[ch].
5376 * Added silc_hash_string_compare to compare two strings in the
5377 hash table. Affected file lib/silcutil/silcutil.[ch].
5379 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Added new function silc_idcache_del_by_context into the
5382 lib/silccore/idcache.[ch].
5384 * Changed the server's ID list routines to use the new ID Cache
5385 interface. Changes around the source tree.
5387 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Added silc_hash_table_del[_by_context]_ext functions in to the
5390 lib/silcutil/silchashtable.[ch].
5392 Removed silc_hash_table_find_all* routines and added new
5393 silc_hash_table_find_foreach to replace them.
5395 Added silc_hash_table_replace_ext function as extended
5396 replacing function. Separated the simple hash table interface
5397 from the extended hash table interface in the file
5398 lib/silcutil/silchashtable.h.
5400 * Fixed minor bugs and changed it to use some of the new
5401 hash table functions in lib/silccore/idcache.c
5403 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Added new function silc_hash_table_find_all to return all keys
5406 in the hash table by the specified key. As the hash table is
5407 collision resistant it also makes it possible to have several
5408 duplicate keys in the hash table. This function may be used to
5409 find all of the keys from the hash.
5411 Added user_context arguments to the SilcHashFunction,
5412 SilcHashCompare and SilcHashDestructor to deliver user specified
5415 Added new fuctions silc_hash_table_find[_all]_ext to do
5416 extended lookup with specified hash and compare functions and
5417 specified user contexts.
5419 Added new function silc_hash_table_add_ext to add the key
5420 with specified hash function and user context.
5422 Added new function silc_hash_table_foreach to traverse all
5423 entrys in the hash table. Added SilcHashForeach callback
5426 Added new function silc_hash_table_del_by_context to delete
5427 the entry only if the context associated with the key matches.
5429 Affected files are lib/silcutil/silchashtable.[ch].
5431 * Removed silc_hash_[server/client/channel]_id and added just
5432 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5433 silc_hash_id_compare to compare two ID's using as the hash table
5434 comparison function. Added also silc_hash_data to hash
5435 binary data and silc_hash_data_compare to compare it.
5437 * Removed silc_idlist_find_client_by_hash as it is not needed
5438 anymore. Affected file silcd/idlist.[ch].
5440 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5441 to use internally the SilcHashTable. The new ID Cache is a lot
5442 faster than the old one. Some of the ID Cache interface was also
5443 rewritten and obsolete and stupid functions were removed.
5445 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added entry_count field to the SilcHashTable to keep the number
5448 of the entries in the table. Implemented the function
5449 silc_hash_table_rehash. Added new function
5450 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5452 Fixed a minor bug in silc_hash_table_free.
5454 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5455 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5456 into the lib/silcutil/silcutil.[ch].
5458 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Implemented a collision resistant hash table into the
5461 lib/silcutil/silchashtable[ch]. See the header and the source
5462 for the SilcHashTable API.
5464 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Merged dotconf version 1.0.2 into lib/dotconf.
5468 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Do not compile anything in lib/silcsim/* if the SIM support
5471 is not enabled. The tree should now compile without problems
5474 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Compiled the SILC under cygwin. Compiled and tested briefly
5477 without problems. More tests needed. The SIMs didn't compile
5480 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5482 * Fixed possible crash in silc_get_username in the
5483 lib/silcutil/silcutil.c.
5485 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Fixed a va_arg in silc/client_ops.c.
5489 * Oops, RC5 routines were named AES and caused some problems
5490 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5492 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Added new SilcIDIP structure into the lib/silccore/id.h and
5495 replaced the old `ip' fields from all SILC ID's to that type.
5496 This is a step towards IPv6 support.
5498 The silc_id_get_len takes now the ID as an extra argument.
5499 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5500 both IPv4 and IPv6 based ID's.
5502 The affected files are lib/silccore/id.[ch] and other files
5503 around the tree using these routines.
5505 * Removed the ID length arguments in server from various
5506 silc_server_send_notify_* routines -> they are not needed
5509 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Fixed memory leak in silc_encode_pem_file in the file
5512 lib/silcutil/silcutil.c.
5514 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Check minor version as well in the SKE. Affected files are
5517 silcd/protocol.c and lib/silcclient/protocol.c.
5519 * Added --identifier option to the server so that an identifier
5520 can be when creating the public key for the server. Affected
5521 file is silcd/silcd.c.
5523 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5524 lib/silccrypt/silcpkcs.c.
5526 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Register default ciphers and stuff when using -C option with
5529 the server. Affected file sildc/silcd.c.
5531 * Put back the servers public key filename format, it is better
5532 than the new one. For now, the client keys are saved with the
5533 new filename format. The affected file silc/client_ops.c.
5535 * Implemented the Cipher API for the rest of the ciphers that
5536 did not implement it or implemented it the wrong way.
5538 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Register default ciphers and stuff when using the -S option
5541 in the client. Affected file silc/silc.c. Same also when
5542 creating new key pair with -C option.
5544 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed the silc_verify_public_key client operation function to
5547 save the public keys differently. The fingerprint is now
5548 used as filename and not the hostname. This way also the
5549 client keys are saved uniquely and not with hostnames. The
5550 affected file is silc/client_ops.c.
5552 * Trimmed the silc_hash_fingerprint function to remove extra
5553 whitespaces from the end of the fingerprint. The affected
5554 file is lib/silccrypt/silchash.c.
5558 * Added silc_cipher_register_default function to register all
5559 default ciphers. It can be used when configuration files
5560 does not exist and the application does not want any specific
5561 ciphers in any specific order.
5563 The SilcDList is now used as silc_cipher_list dynamically
5564 allocated cipher list. Removed the static list all together
5565 and now all ciphers must be allocated to the dynamic list.
5566 The silc_cipher_alloc routine was changed to check only the
5569 All silc_cipher_* routines that used to return int returns
5572 The affected files lib/silccrypt/silccrypt.[ch].
5574 * The same thing was done to silc_hash_* as for silc_cipher_*
5575 routines. Affected files lib/silccrypt/silchash.[ch].
5577 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5578 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5579 Added also silc_pkcs_[un]register[_default] functions.
5580 Removed the data_context from the PKCS API.
5582 * Added silc_hmac_register_default function to register default
5583 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5584 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5585 to unregister all hmacs at once.
5587 * Register the default ciphers, hash functions, PKCSs and HMACs
5588 if client's configuration file does not exist. The affected
5591 * The client did not load the hash functions from the SIM
5592 modules at all. Added support for this. Affected file is
5593 silc/clientconfig.c.
5595 * When decoding public key with silc_pkcs_public_key_decode, check
5596 the supported algorithm only if PKCS are registered. Affected
5597 file lib/silccrypt/silcpkcs.c. The same was done with the
5598 silc_pkcs_private_key_decode.
5600 * Fixed the SILC List routines to keep the list always in order.
5601 It used to change the list's order when traversing the list but
5602 not it preserves the order. Affected file lib/trq/silclist.h.
5604 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added the client library to use the SilcSocketConnection's
5607 reference counter (by silc_socket_dup) to prevent the bug that
5608 the socket object may be freed underneath async operation.
5610 * The name resolv library checking fixes in the configure.in.pre.
5613 * Created new version of the protocol drafts for future
5614 development. The -03 drafts are the ones that will be changed
5615 in the trunk now and the -02 will remain as they are.
5617 * Send list of CUMODE notifys to the router when announcing
5618 the channel users to the router. Affected file silcd/server.c.
5619 If the router receiving channel founder CUMODE for a channel
5620 that already has channel founder it will send CUMODE notify
5621 to the sender to remove the channel founder rights from the
5622 announced client. Affected file silcd/packet_receive.c.
5624 * The CUMODE notify may now use Server ID as well as the entity
5625 who changes the mode. Updated protocool specs.
5627 * Updated INSTALL and README files.
5629 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * New web pages in the http://silc.pspt.fi. The pages was
5636 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Implemented the [DenyConnectin] config section in the server.
5639 Added silc_server_config_denied_conn to check whether incoming
5640 connection is denied. Affected file silcd/serverconfig.[ch].
5642 * Do not check the ports when checking the incoming configuration
5643 data if the port is 0, meaning any. Affected file is
5644 silcd/serverconfig.c.
5646 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Fixed buffer overflow in silc_string_compare in the file
5649 lib/silcutil/silcutil.c.
5651 * Fixed double free in silc_server_command_leave in the file
5654 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Fixed the version checking in the server. Affected file is
5659 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Fixed the configuration data fetching when accepting new
5662 connections in the server. Affected file silcd/server.c.
5664 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Added `sender_entry' argument to the function
5667 silc_server_packet_relay_to_channel so that we can check
5668 whether some destination actually belongs to the same route
5669 the sender belongs (ie, we must not resend the packet to the
5670 sender). Affected file silcd/packet_send.[ch].
5672 * Added `servername' field to the SilcClientEntry in the server
5673 to hold the name of the server where client is from. Affected
5674 file is silcd/idlist.h.
5676 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Moved the channel message encrypting in the router betwen
5679 router connections from silc_server_channel_message to the
5680 silc_server_packet_relay_to_channel since we want to check
5681 whether we have anybody channel before encrypting anything.
5682 Affected files silcd/packet_[receive/send].c.
5684 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Fixed the [AdminConnection] server config section to support
5687 multiple entries. Affected file silcd/serverconfig.c.
5689 * Added support into the server to check the validity of the
5690 incoming connection before executing any KE or authentication
5693 * The connection configuration is now saved to the KE and
5694 connection auth protocol contexts and not fetched anymore in
5695 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5697 * The local hosts listenning address and port is also resolved
5698 now when starting the server. We want to have the socket object
5699 to include the real address and port for the listener. Added
5700 new function silc_net_check_local_by_sock into the files
5701 lib/silcutil/silcnet.[ch].
5703 * Fixed a broadcast bug in server -> do not broadcast if we
5706 * Fixed a routing bug. Do not route broadcast packets ever.
5707 Broadcast packets must be processed always and not routed since
5708 they may be destined to some other host than yourself and thus
5709 would get routed without no good reason. Affected file is
5712 * Added function silc_server_config_is_primary_route to check
5713 whether primary router connection has been configured (a router
5714 configuration that we are initiating). If there is not, we
5715 will assume that there is only two routers in the SILC network
5716 and we will use the incoming router connection as our primary
5717 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5719 * Changed the order of the broadcasting. Broadcast _after_ the
5720 packet has been processed not before. Affected file is
5723 * Fixed a [ClientConnection] parsing bug. The port was never
5724 parsed correctly thus resulting to port 0. Affected file
5725 silcd/serverconfig.c.
5727 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5728 argument and did not set the broadcast packet flag. Affected
5729 file silcd/packet_send.c. Fixed same bug in the function
5730 silc_server_send_notify as well.
5732 * If we receive NEW_ID packet for our own ID in the server, ignore
5735 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Removed the nickname from the Private Message Payload.
5740 Updated the code and the protocol specs.
5742 * Updated protocol specs for submitting to the IETF.
5744 * Tweaked the Random Number Generator a bit. Affected file
5745 lib/silccrypt/silcrng.c. Exported a new function
5746 silc_rng_[global]_add_noise which can be used to add more
5749 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Do not parse packets with different timeout when protocol
5752 is active -> may cause problem with rekey. Affected file
5755 * When server receives signoff notify it must not create
5756 new channel key if the client is on any channels since the
5757 sender of the signoff notify will create it.
5759 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added printing of error messages during SKE protocol from the
5762 failure packet sent by server during SKE. Affected file
5765 * Removed the client's failure_callback handling with timeout
5766 and handle it immediately when received.
5768 * The SKE library returned wrong type in SUCCESS and FAILURE
5769 packets. They must be 32 bit MSB not 16 bit MSB.
5771 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Ok, rewrote the logic of the re-key and now it seems to work.
5774 I tested it on high traffic with frequent re-keys without
5775 problems. Added hmac_receive (and renamed hmac to hmac_send)
5776 in SilcClientConnection in lib/silcclient/client.h and
5777 in SilcIDListData in silcd/idlist.h. Also, removed the
5778 SilcPacketParserContext's cipher and hmac fields as they are
5779 not needed anymore and actually caused some problems when
5780 the ciphers and hmac's changed underneath the packet parser.
5782 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * If re-key protocol is active then process the incoming packets
5785 synchronously since we must assure that icoming packets encrypted
5786 with the old key is processed before the new keys is set to
5787 use. This is true other packets than for REKEY packets.
5788 Affected file silcd/server.c. The same was done to client library
5789 as well, affected file lib/silcclient/client.c.
5791 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed bug in client and server to accept the force send if
5794 the packet is send from silc_[server/client]_packet_process
5795 function. Otherwise the packets are never delivered, oops.
5797 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Disable force sending of packets when REKEY protocol is active.
5800 We must assure that no packet is sent directly when rekey is
5801 performed. All packets must be sent through packet queue.
5802 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5803 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5804 function is silc_[server/client]_packet_send_real to check
5807 * Replaced the SIM paths from example config files to
5808 /usr/local/modules. Also, make install creates now
5809 /usr/local/silc/logs directory to hold all the SILC server
5812 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Made the configure.in.pre work on Solaris. Patch by salo.
5816 * Made all ciphers compatible with non-x86 machines. Defined
5817 CBC mode macros into lib/silccrypt/ciphers_def.h.
5819 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Fixed the make install.
5823 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * When MAC computation fails the silc_packet_decrypt returned 0
5826 even though it was supposed to return -1. Fixed this. The
5827 affected file is lib/silccore/silcpacket.c.
5829 * Do not replace the config files in /etc/silc (in make install)
5830 if they already exist. Affected file ./Makefile.am.
5832 * Do not send re-key packets immediately but through packet queue.
5833 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5835 * Changed silc_net_check_host_by_sock to return FALSE if the
5836 IP/DNS could not be resolved. Though, it returns the IP address
5837 now even if it could not resolve it (but returns also FALSE).
5838 Affected file lib/silcutil/silcnet.[ch].
5840 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added silc_pkcs_decode_identifier to decode the public key's
5843 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5844 Added also silc_pkcs_free_identifier. Added also new context
5845 SilcPublicKeyIdentifier.
5847 * Added -S option to the silc client. It is used to dump the
5848 contents of the specified public key file.
5850 * Changed the PKCS api to return the public key length when
5851 setting the public key.
5853 * Fixed a fatal bug in the public and private key file loading.
5854 Affected file lib/silccrypt/silcpkcs.c.
5856 * Execute the packet parsing for client with zero (0) timeout
5857 if the protocol is active. Affected file silcd/server.c.
5859 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Made the key generation options to the silcd program. Added
5862 -C option, equivalent to client's option.
5864 * Added new [ServerKeys] config section to the server. It
5865 configures the server's public and private key.
5867 * Defined generic Public Key Payload into the protocol
5868 specification to send specific type of public keys and
5871 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5872 public key or certificate.
5874 * Implemented the GETKEY command to the server and to the
5875 client library and on user interface.
5877 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Made preliminary `make install' work.
5881 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added SilcServerRekey context into silcd/idlist.h.
5885 * Added the PFS support as defined in the specification to the
5886 SKE protocol. Affected files lib/silcske/*.c.
5888 * Added `ske_group' field to the SilcServerRekey context to hold
5889 the number of the SKE group that is used with PFS in re-key.
5890 Affected file silcd/idlist.h.
5892 * Added PFS re-key support to the server. Affected file is
5895 * Added silc_protocol_cancel to cancel execution of the next
5896 state of the protocol. Affected file is
5897 lib/silccore/silcprotocol.[ch].
5899 * Added the re-key support with and without PFS to the client
5900 library. Re-key is performed once in an hour, by default.
5902 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5903 Added silc_client_rekey_callback and silc_client_rekey_final.
5904 Affected files are lib/silcclient/protocol.[ch] and
5905 lib/silcclient/client.[ch].
5907 * Removed the `hmac_key' and `hmac_key_len' fields from the
5908 SilcClientConnection structure; not needed. Affected file is
5909 lib/silcclient/client.h.
5913 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Do not ask whether user wants to use the negotiated private key
5916 for private messages, just use it. Affected file is
5917 silc/local_command.c.
5919 * Added `send_enc_key' and `enc_key_len' fields to the
5920 SilcIDListData structure since they are needed in the re-key
5921 phase. Affected file is silcd/idlist.[ch].
5923 * Implemented the simple re-key protocol into the server.
5924 Affected files silcd/server.c and silcd/protocol.[ch]. The
5925 re-key will be performed once in an hour, by default.
5927 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5928 Added silc_server_rekey, silc_server_rekey_callback and
5929 silc_server_rekey_final.
5931 * Removed Tunneled flag from the protocol. Updated the code
5932 and the specifications.
5934 * Adde `pfs' field to the SilcIDListData to indicate whether
5935 the PFS is to be performed in the re-key. Affected file is
5938 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5941 int64 of at least the xintXX size. If void * is less that 4
5942 bytes uint32 * will be used. Defined bool as boolean.
5944 * Changed _ALL_ unsigned long and unsigned int to uint32,
5945 unsgined short to uint16 in the source tree.
5947 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5948 not handle clients that has entry->data.registered == FALSE.
5949 They are not in the network anymore. Affected file is
5952 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Implemented the sending of the SERVER_SIGNOFF notify in the
5955 server. Affected file is silcd/server.c.
5957 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5958 Added also silc_notify_payload_encode_args into the
5959 lib/silccore/silcnotify.[ch].
5961 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5962 Affected file silcd/packet_receive.c.
5964 * Implemented the SERVER_SIGNOFF notify handling in the client
5965 library. Affected file lib/silcclient/client_notify.c. Also,
5966 implemnted the printing of the SERVER_SIGNOFF info to the
5967 application. Affected file silc/client_ops.c.
5969 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5970 if the deleting was successful. Affected file silcd/idlist.[ch].
5972 * Added support for public key authentication in the connection
5973 authentication protocol in the client library. Affected file
5974 lib/silcclient/protocol.c.
5976 * Changed the server's silc_idlist_get_clients_by_* interface
5977 to support already allocated array so that new entries may be
5978 added to pre-allocated array. Affected file silcd/idlist.[ch].
5979 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5980 and command replies.
5982 * All command reply functions in the server now calls the
5983 pending command callback even if error occured. This way the
5984 error will be delivered to the client as well. Affected files
5985 silcd/command.c and silcd/command_reply.c.
5987 * Fixed INFO command to return local server's info if no server
5988 was provided. Affected file lib/silcclient/command.c.
5990 * Removed RESTART command for good. Updated the code and the
5993 * Rewrote parts of the task system. It is a bit simpler now.
5994 Removed unsued task priorities. The affected files are
5995 lib/silcutil/silctask.[ch].
5997 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Moved the USERS printing from the library to the application.
6000 Affected files lib/silcclient/command.c and silc/client_ops.c.
6002 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Added channel key re-key support. The re-key is perfomed
6007 only by the router and is done once in an hour. Added `rekey'
6008 field to the SilcChannelEntry in the server. Affected files
6009 silcd/server.c and silcd/idlist.h.
6011 * Added silc_task_unregister_by_context into the file
6012 lib/silcutil/silctask.[ch].
6014 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Added SILC_UMODE_GONE mode to indicate when the client is not
6017 present in the SILC network. Added also support to the local
6018 command AWAY that will set this mode. Added support of showing
6019 "xxx is gone" in WHOIS command. The USERS command shows the
6020 gone status as well.
6022 * Fixed setting server and router operator privileges in the
6023 server's UMODE command. Affected file silcd/command.c.
6025 * Merged the SKE KE1 and KE2 payloads into one payload. The
6026 new KE payload is equivalent to the old KE2 payload.
6028 Cleaned up the SKE Start Payload parsing. It now uses the
6029 simple buffer unformatting to do the parsing. A lot faster
6032 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6033 to the SKE that is used to indicate whether both of the SKE
6034 parties should perform authentication. By default only the
6035 responder performs authentication. By setting this flag also
6036 the initiator must do authentication. By default it is unset
6037 since in normal SKE case, client to server connection, only
6038 the responder should do authentication. When doing SKE between
6039 two clients both should perform authentication. Updated the
6040 code and the protocol specs.
6042 * A little fix to IDENTIFY command in the server. Search the
6043 client first by hash not nickname. Affected file is
6046 * Fixed the silc_client_close_connection to support closing
6047 the client to client connections wihtout deleting too much
6048 data. Affected file lib/silcclient/client.c.
6050 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6051 are received if protocol used to be active but is not anymore
6052 the application would crash due to NULL pointer dereference.
6053 Affected files silcd/server.c and lib/silcclient/client.c.
6055 * Added `hash' field to the SilcClientConnection to include
6056 the hash function negotiated in the SKE protocol.
6058 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6059 to set the channel founder authentication data. A client can
6060 claim the founder rights later by providing the authentication
6061 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6062 This way the channel founder can regain the channel founder
6063 privileges even it is left the channel. This works only on
6064 local server and the client must be connected to the same
6065 server to be able to regain the founder rights. Updated the
6066 protocol specs accordingly.
6068 Added support to the CMODE command in the client to set the
6069 founder auth data. Read the README to see how to set it.
6071 Added support to the CUMODE command to claim the founder
6072 rights. Read the README to see how to do it.
6074 Added support for the founder authentication to the Channel
6075 Entry in the server. Affected file silcd/idlist.h.
6077 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6078 server's CMODE command. Affected file silcd/command.c.
6080 * Added the following new functions into lib/silccore/silcauth.[ch]:
6081 silc_auth_get_method and silc_auth_get_data.
6083 * The server now saves the remote hosts public key to the
6084 SilcIDListData pointer. Affected file silcd/protocol.c.
6086 * The normal server now does not remove the channel entry from
6087 the cache if the founder authentication data is set. It used
6088 to remove it if the founder was the last one on the channel on
6089 the server and left the channel. The auth data is saved and
6090 if the channel is re-joined later the old entry is used with
6091 the old auth data. Affected files silcd/command_reply.c and
6094 * Removed the `pkcs' field from the SilcIDListData structure
6095 in the server; it is not used. Affected file silcd/idlist.h.
6097 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Fixed packet processing on slow links. Partial packets were
6100 never re-processed because the incoming data buffer was cleared
6101 by the application. Application must not directly clear the
6102 sock->inbuf, the packet processing routines handle it. Fixed
6103 this in client library and in server.
6105 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Fixed the WHOIS and IDENTIFY send reply function to really
6108 check whether to send list or just one entry. Affected file
6111 * Cleaned up the LEAVE command's channel key distribution. The
6112 affected file silcd/command.c.
6114 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6115 can enforce the channel mode as well. In that case the ID
6116 includes the ID of the server. The code now enforces the
6117 mode change if the router have different mode than the server.
6119 * The notify client operation with CMODE_CHANGE notify can now
6120 return NULL client_entry pointer if the CMODE was not changed
6121 by client. Application must check for this.
6123 * Added <Server ID> argument to INFO command to support server
6124 info fetching by Server ID.
6126 * Added silc_server_announce_get_channel_users to get assembled
6127 packets of channel users of the specified channel. Affected
6128 file silcd/server.[ch].
6130 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6131 was freed underneath the ID Cache.
6133 * Re-announce clients when the server received CHANNEL_CHANGE
6134 notify from the router. Affected file silcd/packet_send.c.
6136 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6139 crashed since it did not handle the fact that there is no cipher
6140 called "3" and didn't check the error condition. Now fixed.
6142 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6143 flag. It can be used to send message requests.
6145 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Implemented the RESTART command in the client.
6149 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6150 notice type messages. Added notice printing to the user
6153 * The channel keys are not re-generated if the channel's mode
6154 is PRIVKEY, ie private key on the channel exists. Affected
6155 files silcd/server.c and silcd/command.c.
6157 * Fixed a little bug in channel message delivery when channel
6158 private keys are set in the server. Affected file is
6159 silcd/packet_send.c.
6161 * Changed the setting on channel->on_channel = TRUE from the
6162 silc_client_save_channel_key to the JOIN command reply. The
6163 key payload is not received if the private channel key is set.
6164 Affected file lib/silcclient/command_reply.c and the
6165 lib/silcclient/client_channel.c.
6167 * When the CMODE_CHANGE notify is sent and the channel private
6168 key mode is removed the channel key must be re-generated in
6169 other cells as well. Added this support for the router in the
6170 silcd/packet_receive.c.
6172 * Added new local command NOTICE to send notice message on
6173 channel. Affected file silc/local_command.[ch].
6175 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Added new local command ME to the client. It is used to send
6178 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6179 some action. Affected file silc/local_command.[ch].
6181 * Changed channel_message and private_message client operations
6182 to deliver the message flags to the application. Added also
6183 the `flags' arguments to the silc_client_send_channel_message
6184 and silc_client_send_private_message functions. Affected file
6187 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Redefined the Private Message Payload to support private message
6190 keys and to support the new private message flags. Updated
6191 the protocol specs. Flags makes it possible to have for example
6192 CTCP style messages.
6194 * Added new type SilcPrivateMessagePayload and defined an API
6195 for it in the lib/silcclient/silcprivate.[ch].
6197 * Tested private message private keys successfully. Tested the
6198 private message key set, unset and list commands with the new
6201 * Redefined the Channel Message Payload to include the channel
6202 message flags (equal with private message flags) to support
6203 for example CTCP style messages.
6205 * Defined some of the message (for channel and private message)
6206 flags. Updated the protocol specs and added the flags to the
6207 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6209 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Added SilcKeyAgreementStatus type to the key agreement routines
6212 to indicate the current status and error if one occured.
6213 The status types are defined in the lib/silcclient/silcapi.h.
6215 * Added new local command KEY that is used to set and unset private
6216 keys for channels, set and unset private keys for private messages
6217 with remote clients and to send key agreement requests and
6218 negotiate the key agreement protocol with remote client. The
6219 key agreement is supported only to negotiate private message keys,
6220 it currently cannot be used to negotiate private keys for channels,
6221 as it is not convenient for that purpose.
6223 * Fixed a minor pending callback setting bug in the function
6224 silc_client_get_client_by_id_resolve, now the function works.
6225 Affected file lib/silcclient/idlist.c.
6227 * Added function silc_net_get_local_port to get local bound
6228 port by socket. Added to lib/silcutil/silcnet.[ch].
6230 * Added `sockets' and `sockets_count' fields to the SilcClient
6231 object. They hold the sockets of the listenning sockets in
6232 the client. Listenning sockets may be for example the key
6233 agreement server. Affected file lib/silcclient/client.[ch].
6234 Added functions the silc_client_add_socket and the
6235 silc_client_del_socket. They are exported to the application
6238 * Added ~./silc/clientkeys to support other client's public keys.
6240 * Renamed verify_server_key client operation to verify_public_key
6241 and added one argument to indicate the type of the connection
6242 (server, client etc.).
6244 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added silc_server_connection_auth_request to handle the
6247 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6248 silcd/packet_receive.[ch].
6250 * Added silc_server_send_connection_auth_request into the
6251 silcd/packet_send.c to send the connection auth request packet.
6253 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6256 * Fixed the public key authentication in responder side in the
6257 server. The `auth_data' pointer includes the SilcPublicKey
6258 not the path to the public key. Affected file silcd/protocol.c.
6260 * Implemented the public key authentication in the initiator side
6261 in the server. Affected file silcd/protocol.c.
6263 * Removed the [RedirectClient] config section from the server
6264 configuration. Is not needed and I don't want to implement it.
6266 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Cleaned up the CMODE command in the server. It now works
6269 correctly and supports all the modes defined in the protocol.
6270 Affected file is silcd/command.c.
6272 * Added `hmac_name' field to the SilcChannelEntry in the server
6273 to hold the default HMAC of the channel. It can be set when
6274 creating the channel (with JOIN command). Affected files
6277 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6278 type to indicate the change of the current cipher and hmac
6279 on the channel. Client can safely ignore the <cipher> argument
6280 (if it chooses to do so) since the CHANNEL_KEY packet will
6281 force the channel key change anyway. The <hmac> argument is
6282 important since the client is responsible of setting the new
6283 HMAC and the hmac key into use.
6285 * Fixed the CMODE command in the client library as well.
6287 * Tested CMODE command in router environment successfully.
6289 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Show the version of the remote client (or server) when connecting
6292 to the server. It is logged to the log file. Affected file
6293 is silcd/protocol.c.
6295 * Fixed the KILLED notify handling in the client library. The
6296 client must be removed from all channels when receiving the
6299 Also, do not remove the client entry when giving the KILL
6300 command but when the KILLED notify is received.
6302 * Removed silc_idlist_find_client_by_nickname from the server.
6303 Not needed anymore. Affected files silcd/idlist.[ch].
6305 * Implemented the CHANNEL_CHANGE notify type handling to the
6306 server. Affected file silcd/server.c.
6310 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6313 notify between routers.
6315 * Implemented the INVITE command correctly to the server.
6317 * Implemented the INVITE notify type handling in the server.
6319 * Implemented the INVITE command to the client library and on the
6322 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Added function silc_server_get_client_resolve to find the
6325 client entry by ID from all ID lists and then resolve it
6326 (using WHOIS) if it cannot be found. Affected file is
6329 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Implemented the BAN command to the client library.
6333 * The JOIN command in the server now checks the invite list
6336 * Changed the silc_command_reply_payload_encode_va and the
6337 silc_command_payload_encode_va to support that if argument is
6338 NULL it ignores and checks the next argument. Affected file
6339 lib/silccore/silccommand.c.
6341 * Added silc_server_send_notify_ban to send the BAN notify
6342 type between routers.
6344 * Chaned the silc_notify_payload_encode to support that if
6345 argument is NULL it ignores and checks the next argument.
6346 Affected file lib/silccore/silcnotify.c.
6348 * Tested ban lists in router environment successfully.
6350 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Implemented BAN command to the server, in silcd/command.[ch].
6354 * Removed the BAN and INVITE_LIST modes from the CMODE command
6357 * Added function silc_string_match to regex match two strings.
6358 Affected files lib/silcutil/silcutil.[ch].
6360 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Redefined parts of the SilcChannelEntry in the server to support
6363 the new ban and invite lists.
6365 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Redefined the INVITE command. The same command can be used to
6368 invite individuals to the channel but also to manage the invite
6369 list of the channel (to add to and remove from the invite list).
6370 Updated the protocol specs.
6372 * Added new command SILC_COMMAND_BAN that can be used to manage
6373 the ban list of the channel. Updated the protocol specs.
6375 * Removed the channel modes: the SILC_CMODE_BAN and the
6376 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6377 in the CMODE command. The equivalent features are now available
6378 using INVITE and BAN commands. Updated the protocol specs.
6380 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6381 in the network about change in the current ban list. The notify
6382 type is not used by the client.
6384 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6385 support the invite lists.
6387 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Added new function silc_string_regexify that converts string
6390 including wildcard characters into regex string that can
6391 be used by the GNU regex library. Added into the file
6392 lib/silcutil/silcutil.[ch].
6394 Added silc_string_regex_combine to combine to regex strings
6395 into one so that they can be used as one regex string by
6396 the GNU regex library. Added into the file
6397 lib/silcutil/silcutil.[ch].
6399 Added silc_string_regex_match to match two strings. It returns
6400 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6402 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Imported GNU regex to the soruce tree into lib/contrib.
6405 Fixed some compiler warning from the regex.c.
6407 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Fixed MOTD command in the server to work in router environment.
6411 * Fixed the MOTD command in the client library to support
6412 the server argument in the command.
6414 * Added `nickname_len' argument to the silc_idlist_add_client
6415 in the server, as the `nickname' argument may be binary data
6418 * Added silc_idlist_get_channels to return all channels from
6421 * Implemented LIST command to the server. Affected file is
6424 * Implemented the LIST command to the client library and on the
6427 * Added [<user count>] argument to the LIST command reply.
6428 With private channels the user count is not shown.
6430 * Updated TODO and README.
6432 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * The client entry's data.registered must be TRUE even with
6435 global client entry on global client list. The data.registered
6436 is used to check whether the client is anymore in the network,
6437 for example with WHOWAS command so it must be valid.
6439 * Fixed the WHOWAS command in the server. It now actually works
6440 in router environment. Added function into silcd/command_reply.c
6441 silc_server_command_reply_whowas_save.
6443 * Added silc_idlist_purge function to the silcd/idlist.c
6444 to periodically purge the ID Cache.
6446 * Fixed INFO command in the server. It works now in router
6447 environment. Added <server name> argument to the INFO command
6448 reply. Updated the protocol specs.
6450 * Fixed minor bug in silc_idcache_purge to not purge if the
6451 expire value is zero.
6453 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6454 they were buggy because of the WHOWAS information.
6456 * Fixed local command MSG to handle the async resolving of
6457 the remote client properly. It used to fail the first MSG.
6458 Affected file silc/local_command.c.
6460 * Added `data_len' field to SilcIDCache context.
6462 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Update TODO. Todo in commands in the server.
6466 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6469 used by routers as broadcast packet to inform other routers
6470 about the changed user mode.
6472 Implemented the notify handling in the server. Affected file is
6473 silcd/packet_receive.c. Added the function
6474 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6476 * Added new generic Channel Payload and deprecated the New Channel
6477 Payload. The New Channel Payload is now the generic Channel
6480 * Added new argument `mode' to the silc_server_send_new_channel
6481 as it is required in the Channel Payload now.
6483 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6484 and created a new and real SilChannelPayload to represent the
6485 new generic Channel Payload. Implemented the encode/decode
6486 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6488 * Added silc_server_get_client_channel_list to return the list
6489 of channels the client has joined for WHOIS command reply.
6490 Affected file silcd/server.[ch].
6492 * Implemented the channel list sending in the WHOIS command reply
6493 in server and in the client.
6495 Implemented the channel list displaying on the user interface
6496 as well. Affected file silc/client_ops.c.
6498 * Added silc_channel_payload_parse_list to parse list of Channel
6499 Payloads. It returns SilcDList list of SilcChannelPayloads.
6500 Client for example can use this function to parse the list of
6501 channels it receives in the WHOIS command reply. The caller
6502 must free the list by calling silc_channel_payload_list_free.
6503 Affected files lib/silccore/silcchannel.[ch].
6505 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Added one new argument <user mode> to the WHOIS command reply
6508 to return the mode of the user in SILC. Updated the protocol
6511 Implemented it to the server and client.
6513 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Fixed the mode printing on the user interface on joining.
6516 Affected file silc/client_ops.c.
6518 * Implemented the UMODE command and user modes in general to the
6519 client library and to the user interface.
6521 * Implemented the UMODE command to the server.
6523 * The server now sends UNKNOWN_COMMAND error status if client sends
6524 unknown command. Affected file silcd/command.c.
6526 * All server commands now handle the command identifier the right
6527 way when sending the command reply to the client. The client can
6528 use to identify the command replies with the identifier.
6530 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Added silc_server_get_client_route to resolve the route to
6533 the client indicated by the client ID. Affected file is
6536 * Added silc_server_relay_packet as general function to relay
6537 packet to arbitrary destination. This deprecates functions
6538 like _send_private_message_key, _relay_notify etc. Affected
6539 file is silcd/packet_send.[ch].
6541 Removed silc_server_send_key_agreement,
6542 silc_server_send_private_message_key and
6543 silc_server_packet_relay_notify functions from the file
6544 silcd/packet_send.[ch].
6548 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6549 server. Affected file silcd/packet_receive.[ch].
6551 * Implemented the KILL command to the client. Implemented the
6552 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6553 Affected files lib/silcclient/command[_reply].c and
6554 lib/silcclient/client_notify.c. Implemented the KILL notify
6555 printing in the user inteface.
6557 * Fixed a lot silc_parse_nick memory leaks from the client
6558 library in the file lib/silcclient/command.c.
6560 * Changed the silc_server_send_notify_on_channels's `sender'
6561 argument from SilcSocketConnection to SilcClientEntry to
6562 check the sender as entry and not as connection object and not
6563 to send to the client provided as argument. The affected file
6564 is silcd/packet_send.[ch].
6566 * The notify packets that are destined directly to the client used
6567 to not to be processed by the server. Now changed that and the
6568 server processes all notify packets. After relaying the packet
6569 to the client the notify packet is processed in the server.
6571 * The silc_server_free_client_data now checks whether there is
6572 pending outgoing traffic for the client and purges the data to
6573 the network before removing the client entry.
6575 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6578 an client is killed from the SILC Network. Updated the protocol
6581 Added new function silc_server_send_notify_killed to the
6582 silcd/packet_send.[ch].
6584 * Added function silc_server_packet_relay_notify to relay notify
6585 packets that are destined directly to a client. In this case
6586 the server does not process the notify packets but merely relays
6587 it to the client. Affected file silcd/packet_send.[ch].
6589 Added also silc_server_packet_process_relay_notify to check
6590 whereto relay the notify. Affected file is
6591 silcd/packet_receive.[ch].
6593 * Implemented the KILL command to the server.
6597 * Added the backup schema desgined last fall to the protocol
6598 specs for everyone to see. The specification is in the
6599 *-spec-xx.txt draft and the packet type definitions for the
6600 backup routers is in *-pp-xx.txt draft. Thusly, added also
6601 new packet type SILC_PACKET_CELL_ROUTERS.
6603 * A big security problem in the implementation discovered. The
6604 signoff of an client did not cause new channel key generation
6605 which it of course should've done. The channel keys must be
6606 always re-generated when client leaves (or signoffs) the channel.
6607 The silc_server_remove_from_channels funtion now handles
6608 the channel key re-generation.
6610 * Added `sender' argument to the silc_server_send_notify_on_channels
6611 to not to send the client provided as argument. Affected file
6612 silcd/packet_send.[ch].
6614 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * Implemented OPER and SILCOPER commands into the server and
6619 * Added silc_auth_verify and silc_auth_verify_data to verify
6620 the authentication directly from the authentication payload.
6621 It supports verifying both passphrase and public key based
6622 authentication. Affected file lib/silccore/silcauth.[ch].
6624 * Added `hash' field to the SilcIDListData structure. It is the
6625 hash negotiated in the SKE protocol. Affected file is
6628 * Slight redesigning of the SilcAuthPayload handling routines.
6629 Do not send SilcPKCS but SilcPublicKey as argument.
6631 * Implemented the public key authentication support to the
6632 serverconfig. The public key is loaded from the provided path
6633 and saved as authentication data to void * pointer. Thus,
6634 changed the unsigned char *auth_data to void *auth_data;
6636 * Fixed SHUTDOWN command to send the reply before the server
6637 is shutdown. :) Affected file silcd/command.c.
6639 * Fixed fatal bug in CONNECT command. The hostname was invalid
6640 memory and server crashed. Affected file silcd/command.c.
6642 * Fixed fatal bug in CLOSE command. The server_entry became
6643 invalid but was referenced later in the command. Affected file
6646 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Fixed fatal bug in failure packet handling. Server ignored
6649 the failure and thus crashed when it came.
6653 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6656 that the command may be executed only once in (about) 2 seconds.
6657 The old SILC_CF_LAG flag is same but allows command bursts up
6658 to five before limiting.
6660 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6661 server code. Various commands now includes the CF_LAG_STRICT
6662 flag to disallow any kind of miss-use of the command.
6664 * Fixed the silc_buffer_unformat to not to allocate any data
6665 if the length of the data is zero. It used to allocate the
6666 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6668 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Changed the format of AdminConnection configuration section
6671 in the server. Added username of the admin to the format.
6672 Affected files silcd/serverconfig.[ch].
6674 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6675 to return admin configuration data by host, username and/or
6678 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Implemented WHOWAS command to the server. Added the functions:
6682 silc_server_command_whowas_parse,
6683 silc_server_command_whowas_send_reply,
6684 silc_server_command_whowas_from_client and
6685 silc_server_command_whowas_from_server
6687 * Added <Client ID> argument to the WHOWAS command reply. Updated
6688 the protocol specs accordingly.
6690 * Implemented WHOWAS command and command_reply to the client
6693 Implemented the WHOWAS printing on the user interface.
6695 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added new argument to the WHOWAS command reply, the real name.
6698 It is an optional argument. Updated the protocol specs.
6700 * Added SilcIDCacheDestructor callback that is registered when
6701 the SilcIDCache is allocated. The callback is called when
6702 an cache entry in the ID Cache expires, or is purged from the
6703 cache. Added into lib/silccore/idcache.[ch].
6705 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6706 to destruct the client entries when the cache entry expires.
6707 Other ID Cache's in server and in the client library ignores
6710 * If the ID Cache entry's `expire' field is zero then the entry
6711 never expires. Added boolean `expire' argument to the
6712 silc_idcache_add function in the lib/silccore/idcache.[ch].
6713 If it is TRUE the default expiry value is used.
6715 * Added silc_server_free_client_data_timeout that is registered
6716 when client disconnects. By default for 5 minutes we preserve
6717 the client entry for history - for WHOWAS command.
6719 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Added support to the server to enforce that commands are not
6722 executed more than once in 2 seconds. If server receives
6723 commands from client more frequently, timeout is registered
6724 to process the commands. Affected file silcd/command.c.
6725 Added new function silc_server_command_process_timeout.
6727 * Changed NICK_NOTIFY handling in client library to check that
6728 if the client's nickname was changed, so there is no need to
6729 resolve anything from the server.
6731 * Removed error printing from the WHOIS and IDENTIFY commands.
6732 If error occurs then it is ignored silently in the client library.
6733 The application, however, may map the received error to
6734 human readable error string. The application currently maps
6735 the NO_SUCH_NICKNAME error to string.
6737 * Made the command status message public to the application. Moved
6738 them from lib/silcclient/command_reply.c to
6739 lib/silcclient/command_reply.h. The application can map the
6740 received command status to the string with the
6741 silc_client_command_status_message function.
6743 * Added check to the server to check that client's ID is same
6744 as the Source ID in the packet the client sent. They must
6747 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Added dist-bzip hook to the Makefile.am to make bzip2
6750 compressed distributions.
6752 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Server now enforces the maximum length for the nickname and
6755 the channel as protocol specification dictates. 128 bytes for
6756 nickname and 256 bytes for channel name.
6758 * Moved the WHOIS printing to the application. The client libary
6759 does not print out the WHOIS information anymore, the application
6760 must do it. Renamed silc_client_command_reply_whois_print to
6761 the silc_client_command_reply_whois_save.
6763 The client's idle time is also sent to the application now, and
6764 the idle is shown on screen.
6766 * Added silc_client_command_reply_identify_save to save the
6767 received IDENTIFY entries.
6769 * Do not check for channel private keys in message sending and
6770 reception if the channel does not have the PRIVKEY mode set.
6771 Affected file lib/silclient/client_channel.c.
6773 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6776 just surfaced after chaning the JOIN procedure.
6778 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added silc_client_get_clients_by_list to get client entries
6781 from Client ID list, that is returned for example by JOIN
6782 and USERS command replies. The application should use this
6783 function for example when JOIN command reply is received to
6784 resolve the clients already on the channel (library does not
6785 do that anymore as USERS command reply is not used in the JOIN
6786 procedure anymore). Affected files lib/silcclient/silcapi.h and
6787 lib/silcclient/idlist.c.
6789 * JOIN command reply and USERS command reply returns now SilcBuffer
6790 pointers instead of unsigned char pointers when returning
6791 the client list and mode list.
6793 * Added <Client ID> argument to the JOIN command reply, mainly
6794 for the server to identify for which client the command was
6795 originally sent. Updated protocol specs accordingly.
6797 * Added SilcDlist private_key pointer to the SilcChannelEntry
6798 in the client to support the channel private keys. Affected
6799 file is lib/silcclient/idlist.h.
6801 * Added SilcChannelPrivateKey argument to the function
6802 silc_client_send_channel_message so that application can choose
6803 to use specific private ke if it wants to. If it is not provided,
6804 the normal channel key is used, unless private keys are set.
6805 In this case the first (key that was added first) is used
6806 as the encryption key.
6808 * Implemented the support for channel private key handling.
6809 Implemented the following functions:
6811 silc_client_add_channel_private_key,
6812 silc_client_del_channel_private_keys,
6813 silc_client_del_channel_private_key,
6814 silc_client_list_channel_private_keys and
6815 silc_client_free_channel_private_keys
6817 Affected file lib/silcclient/client_channel.c.
6819 * Added the support for the private keys in the channel message
6820 sending and encryption and in the message reception and
6821 decryption. Affected funtions are
6822 silc_client_send_channel_message and silc_client_channel_message.
6824 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Added SKE's key verify callback to the client library's
6827 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6829 * Removed the statement that server (or router) must send USERS
6830 command reply when joining to the channel so that the client
6831 knows who are on the channel. Instead, the client list and
6832 client's mode list is now sent in the JOIN command reply to the
6833 client who joined channel. This is better solution.
6835 * Added function silc_server_get_users_on_channel and function
6836 silc_server_save_users_on_channel to the silcd/server.[ch].
6838 * Removed function silc_server_command_send_users from the
6841 * Do not show topic on the client library anymore. The topic is
6842 sent in the command reply notify to the application and the
6843 application must show the topic now.
6845 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added client searching by nickname hash into the IDENTIFY and
6848 WHOIS commands in the server as they were clearly missing from
6849 them. Affected file is silcd/command.c.
6851 * Fixed a bug in private message receiving in the client library.
6852 The remote ID was freed and it wasn't supposed, now it is
6855 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Minor fix to the channel payload; allocate the data area, as it
6858 needs to be of specific length.
6860 * If the key agreement port is zero then the operating
6861 system will define the bound port. Affected files are
6862 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6864 * Added new function silc_channel_payload_decrypt into the file
6865 lib/silccore/silcchannel.[ch].
6867 * Moved the channel message etc, check from silc_packet_decrypt
6868 to applications. The library calls now a generic
6869 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6870 when the packet is either normal or special. This was done to
6871 allow more wide range of checking that was not allowed when
6872 the code was in library. Now applications can do virtually any
6873 checks to the packet and return to the library the decision how
6874 the packet should be processed. Affected files are
6875 lib/silccore/silcpacket.[ch].
6877 Added silc_server_packet_decrypt_check to the server and
6878 silc_client_packet_decrypt_check to the client library.
6880 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6881 to send with specified source and destination information.
6883 * Channel message delivery between routers was broken after the
6884 channel key distribution was fixed earlier. The channel key
6885 was used be to distributed to other routers as well which is not
6886 allowed by the protocol. Now this is fixed and channel keys
6887 really are cell specific and the channel message delivery between
6888 routers comply with the protocol specification.
6890 * Fixed various commands in server to check also the global list
6891 for the channel entry and not just the local list. The affected
6892 file silcd/command.c.
6894 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Added assert()s to buffer formatting and unformatting routines
6897 to assert (if --enable-debug) when error occurs. Affected
6898 file: lib/silcutil/silcbuffmt.c.
6900 * Changed to auto-reconnect to check whether the remote host is
6901 router and register the re-connect timeout if it is. It used
6902 to check that whether we are normal server, but router must do
6903 auto-reconnect with another router as well. Affected file
6906 * Removed the [<key len>] option from CMODE command as the cipher
6907 name decides the key length, nowadays. See the defined ciphers
6908 from the protocol specification.
6910 * Added [<hmac>] option to the CMODE command to define the HMAC
6911 for the channel. Added SILC_CMODE_HMAC channel mode.
6913 * Added [<hmac>] option for the JOIN command so that user can
6914 select which HMAC is used to compute the MACs of the channel
6917 * Added Hmac field to the Channel Message Payload. The integrity
6918 of plaintext channel messages are now protected by computing
6919 MAC of the message and attaching the MAC to the payload. The
6920 MAC is encrypted. Now, it is clear that this causes some
6921 overhead to the size of the packet but rationale for this is that
6922 now the receiver can verify whether the channel message decrypted
6923 correctly and also when private keys are set for the channel the
6924 receiver can decrypt the packet with several keys and check from
6925 the MAC which key decrypted the message correctly.
6927 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6928 lib/silccrypt/silccipher.[ch].
6930 * Added silc_hash_len to return the digest length into the
6931 lib/silcrypt/silchash.[ch].
6933 * Rewrote parts of Silc Channel Payload interface in the
6934 lib/silccore/silcchannel.[ch]. The encode function now also
6935 encrypts the packet and parse function decrypts it.
6937 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Fixed a minor formatting bug in the SKE's key material processing.
6940 It actually might have processed the keys wrong way resulting
6943 * Redefined the mandatory HMAC algorithms and added new algorithms.
6944 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6945 and hmac-md5 truncated to 96 bits. The mandatory is now
6946 hmac-sha1-96. Rest are optional (including the one that used
6947 to be mandatory). Rationale for this is that the truncated HMAC
6948 length is sufficient from security point of view and can actually
6949 make the attack against the HMAC harder. Also, the truncated
6950 HMAC causes less overhead to the packets. See the RFC2104 for
6953 * Added new [hmac] configuration section. The SKE used to use
6954 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6955 is of course wrong. The official names that must be proposed in
6956 the SKE are the ones defined in the protocol specification
6957 (hmac-sha1-96 for example). The user can configure any hmac
6958 using any hash function configured in the [hash] section. At
6959 least, the mandatory must be configured.
6961 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6963 * Added HMAC list to the SKE proposal list. It has now both
6964 hash algorithm list and HMAC list. This makes the protocol
6965 incompatible with previous versions. The SKE now seems to work
6966 the way it is supposed to work, for the first time actually.
6968 * Defined plain Hash algorithms to the protocol specification.
6971 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Implemented support for key agreement packets into the server.
6974 Added functions silc_server_key_agreement and
6975 silc_server_send_key_agreement. Other than these functions,
6976 server has nothing to do with this packet.
6978 * Added support for private message key packets into the server.
6979 Added functions silc_server_private_message_key and
6980 silc_server_send_private_message_key.
6984 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6985 called in the protocol's final callback instead in the END
6986 protocol state. This makes a little more sense and in the same
6987 time in client we can use the same protocol routines for normal
6988 key exchange and to key agreement packet handling as well.
6990 * Added to both client's and server's KE protocol context the
6991 SilcSKEKeyMaterial pointer to save the key material. We will
6992 bring the key material to the protocol's final callback by doing
6993 this. The final callback must free the key material.
6995 * Added SKE's packet_send callback into client's KE protocol
6996 context so that the caller can choose what packet sending function
6997 is used. This way we can use different packet sending when
6998 doing normal SKE when doing key agreement packet handling (in
6999 the key agreement packet handling we do not want to encrypt
7002 * Implemented the responder side of the key agreement routines
7003 in the client. The client can now bind to specified port and
7004 accept incoming key negotiation. The key material is passed
7005 to the application after the protocol is over.
7007 * Implemented the processing of incoming Key Agreement packet
7008 in the client. Added function silc_client_key_agreement to
7011 * Implemented the intiator side of the key agreement routines
7012 in the client. The client can now initiate key agreement with
7013 another remote client. The key material is passed to the
7014 application after the protocol is over.
7016 * Created client_keyagr.c to include all the key agreement
7019 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7020 SILC_TASK_CALLBACK except that it is not static.
7022 * Created client_notify.c and moved the Notify packet handling
7023 from the client.[ch] into that file.
7025 * Created client_prvmsg.c and moved all private message and
7026 private message key routines from the client.[ch] into that file.
7028 * Create client_channel.c and moved all channel message and
7029 channel private key routines from the client.[ch] into that file.
7031 * Changed silc_client_get_client_by_id_resolve to resolve with
7032 WHOIS command instead of IDENTIFY command, in the file
7033 lib/silclient/idlist.c.
7035 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * Implemented the SKE's responder side to the Client library.
7039 * When FAILURE is received to the protocol do not trust it
7040 blindly. Register a timeout to wait whether the remote closes
7041 the connection as it should do it, only after that process the
7042 actual failure. This was changed to both client and server.
7044 * Added client_internal.h to include some of the structures
7045 there instead of client.h in lib/silcclient/.
7047 * Added function silc_task_unregister_by_callback to unregister
7048 timeouts by the callback function.
7050 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Some "Incomplete WHOIS info" errors has been appearing on the
7053 log files. Took away the entry->userinfo check from WHOIS
7054 reply sending. The entry->userinfo is now " " if client did not
7055 provide one. I thought this was fixed earlier but something
7056 is wrong still. Let's see if the error still appears.
7058 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Fixed a minor bug in the login when the channel key is
7061 re-generated in the server. It used to generate the key in
7062 wrong order and thus caused problems in the channel traffic.
7064 * Fixed a minor bug in channel key distsribution after
7065 KICK command. The key was not sent to the router even though
7068 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7070 * Added silc_ske_process_key_material_data as generic routine
7071 to process any key material as the SILC protocol dictates. The
7072 function is used by the actual SKE library but can be used by
7073 applications as well. This relates to the private message keys
7074 and the channel private keys since they must be processed the
7075 same way the normal SILC session keys. The protocol dictates
7076 this. Affected files: lib/silcske/silcske.[ch].
7078 Added also silc_ske_free_key_material to free the
7079 SilcSKEKeyMaterial structure.
7081 * Defined silc_cipher_set_key function to set the key for
7082 cipher without using the object's method function. The affected
7083 files: lib/silccrypt/silccipher.[ch].
7085 * Implemented silc silc_client_add_private_message_key,
7086 silc_client_add_private_message_key_ske,
7087 silc_client_del_private_message_key,
7088 silc_client_list_private_message_keys and
7089 silc_client_free_private_message_keys functions in the
7092 Added functions silc_client_send_private_message_key to send
7093 the Private Message Key payload and silc_client_private_message_key
7094 to handle incoming Private Message Key payload.
7096 * Added Cipher field to the Private Message Key payload to set
7097 the cipher to be used. If ignored, the default cipher defined
7098 in the SILC protocol (aes-256-cbc) is used.
7100 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Removed lib/silcclient/ops.h file.
7104 Redefined parts of the SILC Client Library API. Created new
7105 file silcapi.h that deprecates the ops.h file and defines the
7106 published Client Library API. Defined also private message key
7107 API and channel private key API into the file.
7109 This is the file that the application must include from the
7110 SILC Client Library. Other files need not be included by
7111 the application anymore.
7113 * Added new key_agreement client operation callback and also
7114 defined the Key Agreement library API for the application.
7116 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7119 is used by clients to request key negotiation between another
7120 client in the SILC network. If the negotiation is started it
7121 is performed using the SKE protocol. The result of the
7122 negotiation, the secret key material, can be used for example
7123 as private message key.
7125 Implemented the Key Agreement payload into the files
7126 lib/silccore/silauth.[ch].
7128 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7130 * Redefined ciphers for the SILC protocol. Added some new ciphers
7131 and defined the key lengths for the algorithms. Changed the
7132 code accordingly. The default key length is now 256 bits.
7134 * Fixed SKE key distribution function silc_ske_process_key_material
7135 when the key length is more than 128 bits. The default key
7136 length in SILC is now 256 bits.
7138 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7139 to indicate unsupported algorithm.
7141 * Renamed rijndael.c to aes.c and all functions as well.
7143 * Fixed a long standing channel key setting bug in client library.
7144 Weird that it has never surfaced before.
7146 * Fixed bug in channel deletion. If the entire channel is removed
7147 then it must also delete the references of the channel entry
7148 from the client's channel list as the client's channel entry and
7149 the channel's client entry share same memory.
7151 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Implemented CONNECT and SHUTDOWN commands in the client.
7155 * Implemented CLOSE command to the client.
7157 * Added the function silc_idlist_find_server_by_name into the
7158 files silcd/idlist.[ch].
7160 Added the function silc_idlist_find_server_by_conn into the
7161 files silcd/idlist.[ch].
7163 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * DIE command was renamed to SHUTDOWN. Updated the both code
7168 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7169 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7171 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7174 * Added function silc_server_create_connection function to create
7175 connection to remote router. My server implementation actually
7176 does not allow router to connect to normal server (it expects
7177 that normal server always initiates the connection to the router)
7178 so the CONNECT command is only good for connecting to another
7181 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7184 or some other client was kicked from the channel.
7186 Implemented the handling of the notify type to both client
7189 Implemented silc_server_send_notify_kicked to send the KICKED
7190 notify. It is used to send it to the server's primary router.
7192 * Implemented the KICK command into server and client.
7194 * Added `query' argument to the silc_idlist_get_client function
7195 to indicate whether to query the client from server or not if
7198 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7199 to indicate that the client is not channel founder.
7203 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Removed the rng context from SilcPacketContext structure and
7206 changed that the packet routine uses the Global RNG API.
7208 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Added support for quit message that client can "leave" on the
7211 channel when it quits the SILC. It is ditributed inside the
7212 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7214 Added silc_server_free_client_data that will take the
7215 signoff message as argument.
7217 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7219 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Updated parts of the protocol specification to keep it up
7224 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7226 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7227 payloads in one packet.
7229 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7230 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7231 use now the new List flag.
7233 * Also deprecated the following packet types: REPLACE_ID,
7234 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7236 * Added list support for Notify packet in server.
7238 * Added silc_server_send_notify_channel_change to send the
7239 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7240 the silc_server_send_replace_id.
7242 * Added silc_server_send_notify_nick_change to send the
7243 NICK_CHANGE notify type. Deprecates the function
7244 silc_server_send_replace_id.
7246 * Added silc_server_send_notify_join to send the JOIN notify type.
7247 Deprecates the function silc_server_send_new_channel_user.
7249 * Added silc_server_send_notify_leave to send LEAVE notify type.
7250 Deprecates the function silc_server_send_remove_channel_user.
7252 * Added silc_server_send_notify_cmode and
7253 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7254 types. Deprecates the silc_server_send_set_mode function.
7256 * Added SERVER_SIGNOFF notify type to indicate that server has
7257 quit. This means that all clients on the channel from that
7258 server will drop. This can be also used when netsplit happens.
7260 Deprecated REMOVE_ID packet type since it is not needed anymore
7263 Added silc_server_send_notify_server_signoff to send the
7264 SERVER_SIGNOFF notify type. Deprecates the function
7265 silc_server_send_remove_id.
7267 Added also silc_server_send_notify_signoff to send the
7268 SIGNOFF notify type.
7270 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7271 SILC protocol from this day on. Changed the protocol
7272 specification as well.
7274 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7275 notify type. It is used between routers to notify about
7276 topic changes on a channel.
7278 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7281 * Partly updated the protocol specification to comply with the
7282 changes now made. It is still though a bit outdated.
7284 * The JOIN notify type now takes one extra argument <Channel ID>.
7285 The packet used to be destined to the channel but now the
7286 JOIN type may be sent as list thus it is impossible to
7287 destine it to any specific channel. By adding this argument
7288 it is again possible.
7290 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Added CREDITS file. The CHANGES and CREDITS file will appear
7293 in the distribution as well.
7295 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7298 types in the server's silcd/packet_receive.c.
7300 * Implemented CMODE and CUMODE to work in router environment.
7302 * Fixed minor encoding and decoding buglet from the
7303 lib/silccore/silcmode.c.
7305 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7308 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7310 * Changed all SilcConfigServer* and silc_config_server* to
7311 SilcServerConfig* and silc_server_config*, respectively.
7314 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Associated the ID (client or server ID) to the Authentication
7317 Payload to avoid any possibility of forging. Updated the
7318 protocol specification and the code accordingly.
7320 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * The RSA key length is now save to the RsaKey context in the
7323 key generation process in lib/silccrypt/rsa.c. The key length
7324 is now used to figure out the maximum size of the block allowed
7325 to be encrypted/signed.
7327 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7328 is equivalent to the silc_mp_mp2bin but does not allocate any
7331 * Changed silc_mp_mp2bin API to take length argument. If it is
7332 non-zero then the buffer is allocated that large. If zero, then
7333 the size is approximated using silc_mp_sizeinbase, which however
7336 * Created Global RNG API which is global RNG that application can
7337 initialize. After initializing, any routine anywhere in the
7338 code (including library) can use RNG without allocating a new
7339 RNG object. This was done to allow this sort of use of the
7340 RNG in code that has no chance to allocate RNG object. All
7341 applications currently allocate this and many routines in the
7342 library use this. Affected file lib/silccrypt/silcrng.[ch].
7344 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7345 it to use the Global RNG API.
7347 * Defined Authentication Payload into protocol specification that
7348 is used during SILC session to authenticate entities. It is
7349 used for example by client to authenticate itself to the server
7350 to obtain server operator privileges.
7352 Implemented this payload into the lib/silccore/silcauth.[ch].
7353 Implemented also routines for public key based authentication
7354 as the new protocol specification dictates.
7356 Moved definitions of different authentication methods from
7357 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7359 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7360 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7361 silc_pkcs_verify_with_hash functions into the file
7362 lib/silccrypt/silcpkcs.[ch].
7364 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * The client entry's userinfo pointer must be always valid.
7367 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7368 will fail since it requires the userinfo. Now, the userinfo
7369 is allocated as "" if actual userinfo does not exist. Actually,
7370 it must exist and it is totally Ok to drop client connections
7371 that does not announce the userinfo. However, we will make
7372 this workaround for now.
7374 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7375 to return the remote port by socket.
7377 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7379 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7380 SILC_SERVER_PENDING_EXEC and added an new macro
7381 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7382 data or when error occurs while processing the pending command.
7384 Added new argument `destructor' into silc_server_command_pending
7385 and to the SilcServerCommandPending object. This destructor is
7386 now called after calling the pending callback or if error occurs
7387 immediately. If error occurs the actual pending callback won't
7388 be called at all - only the destructor. The destructor may be
7389 NULL if destructor is not needed.
7391 All this applies for client library code as well. Similar
7392 changes were made there as well for the pending commands.
7394 In the client, the application must now allocate the
7395 SilcClientCommandContext with the silc_client_command_alloc
7398 * Added reference counter to the SilcServerCommandContext. Added
7399 function silc_server_command_alloc and silc_server_command_dup
7402 Same type of functions added to the client library for the same
7405 * Removed the cmd_ident from IDListData away since it is now
7406 global for all connections. It is the command identifier used
7407 in command sending and with pending commands. The affected file
7410 * Added reference counter to the SilcSocketConnection objecet to
7411 indicate the usage count of the object. The object won't be
7412 freed untill the reference counter hits zero. Currently only
7413 server uses this, and client ignores it. The client must be
7414 set to use this too later. The affected files are
7415 lib/silccore/silcsockconn.[ch]. Added also the function
7416 silc_socket_dup to increase the reference counter.
7418 This was mainly added because it is possible that the socket
7419 is removed underneath of pending command or other async
7420 operation. Now it won't be free'd and proper DISCONNECTING
7421 flags, etc. can be set to avoid sending data to connection that
7422 is not valid anymore.
7424 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7425 the connection. After that it sets SILC_SET_DISCONNECTED.
7426 It is, however, possible that the socket data is not still freed.
7427 The silc_server_packet_process now checks that data is not
7428 read or written to connection that is DISCONNECTED. The socket
7429 get's freed when the reference counter hits zero.
7431 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Changed the client operation API: channel_message operation's
7434 `sender' is now the client entry of the sender, not the nickname
7435 and the `channel' is the channel entry, not the channel name.
7437 In the private_message operation the `sender' is now also the
7438 client entry of the sender not the nickname.
7440 Affected file is lib/silcclient/ops.h and all applications
7441 using the client operations.
7443 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Moved the calling of ops->connect() from connect_to_server_final
7446 into receive_new_id functin since that is the point when the
7447 client is actually allowed to send traffic to network. The
7448 affected file is lib/silcclient/client.c.
7450 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7452 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7453 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7454 (if needs broadcasting) instead of broadcasting the packets one
7455 by one which would make a burst in the network traffic.
7457 * Added `broadcast' argument to the functions in silcd/server.[ch]
7458 silc_server_create_new_channel[_with_id] to indicate whether
7459 to send New Channel packet to primary router.
7461 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7463 * Added new function into the silcd/server.[ch] files:
7464 silc_server_create_new_channel_with_id to create new channel with
7465 already existing Channel ID.
7467 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7468 lib/silccore/silcpacket.h. This packet is used t send list of
7469 Set Mode payloads inside one packet. Server uses this to set
7470 the modes for the channels and clients on those channels, that it
7471 announced to the router when it connected to it. The protocol
7472 specification has been updated accordingly.
7474 * The silc_server_new_channel did not handle the packet coming
7475 from normal server as it normally does not send that. However,
7476 when it announces its channels it does send it. Implemented
7477 the support for that.
7479 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7480 into the file lib/silccore/id.h.
7482 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Fixed memory leaks in the functions silc_idlist_del_client,
7485 silc_idlist_del_channel and silc_idlist_del_server in the file
7486 silcd/idlist.c. All of those leaked like a sieve.
7488 * Fixed some small memory leaks in the client's function
7489 silc_client_notify_by_server.
7491 * Added functions into silcd/server.c: silc_server_announce_clients,
7492 silc_server_announce_channels and silc_server_announce_server.
7493 These functions are used by normal and router server to announce
7494 to its primary router about clients, channels and servers (when
7495 router) that we own. This is done after we've connected to the
7498 These functions effectively implements the following packet types:
7499 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7500 and SILC_PACKET_NEW_ID_LIST.
7502 * Added new functions into the silcd/packet_receive.[ch]:
7503 silc_server_new_id_list, silc_server_new_channel_list and
7504 silc_server_new_channel_user_list to handle the incoming
7505 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7507 * Added support of changing Channel ID in the function
7508 silc_server_replace_id. If the server that announces a channel
7509 to the router already exists in the router (with same name but
7510 with different Channel ID), router is responsible to send
7511 Replace ID packet to the server and force the server to change
7512 the Channel ID to the one router has.
7514 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7515 client that the Channel ID has been changed by the router. The
7516 normal server sends this to the client. Client must start using
7517 the new Channel ID as the channel's ID.
7519 Implemented handling of this new type into lib/silcclient/client.c
7520 into the function silc_client_notify_by_server.
7522 * Added new function silc_idlist_replace_channel_id into the files
7523 silcd/idlist.[ch] to replace the Channel ID.
7525 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Call silc_server_command_identify_check always when processing
7528 the IDENTIFY command in silcd/command.c
7530 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7533 send keepalive packets. The packet can be sent by clients,
7534 servers and routers.
7536 Added function silc_socket_set_heartbeat into the file
7537 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7538 If not set, the heartbeat is not performed. The actual
7539 heartbeat is implemented in the low level socket connection
7540 library. However, application is responsible of actually
7543 Added silc_server_send_heartbeat to send the actual heartbeat
7544 packet into silcd/packet_send.[ch]. Server now performs
7545 keepalive with all connections.
7547 * Added silc_task_get_first function into lib/silcutil/silctask.c
7548 to return the timeout task with shortest timeout. There was a bug
7549 in task unregistration that caused problems. TODO has been
7550 updated to include that task system must be rewritten.
7552 * The client library will now resolve the client information when
7553 receiving JOIN notify from server for client that we know but
7554 have incomplete information.
7556 * Rewrote parts of silc_server_remove_from_channels and
7557 silc_server_remove_from_one_channel as they did not remove the
7558 channel in some circumstances even though they should've.
7560 * Encryption problem encountered in server:
7562 The LEAVE command used to send the Channel Key packet to the
7563 router immediately after generating it. However, the code
7564 had earlier sent Remove Channel user packet but not immediately,
7565 ie. it was put to queue. The order of packets in the router
7566 was that Channel Key packet was first and Remove Channel User
7567 packet was second, even though they were encrypted in the
7568 reverse order. For this reason, MAC check failed. Now, this
7569 is fixed by not sending the Channel Key packet immediately but
7570 putting it to queue. However, this is more fundamental problem:
7571 packets that are in queue should actually not be encrypted
7572 because packets that are sent immediately gets encrypted
7573 actually with wrong IV (and thus MAC check fails). So, packets
7574 that are in queue should be encrypted when they are sent to
7575 the wire and not when they put to the queue.
7577 However, the problem is that the current system has not been
7578 designed to work that way. Instead, the packet is encrypted
7579 as soon as possible and left to the queue. The queue is then
7580 just purged into wire. There won't be any fixes for this
7581 any time soon. So, the current semantic for packet sending
7584 o If you send packet to remote host and do not force the send
7585 (the packet will be in queue) then all subsequent packets to the
7586 same remote host must also be put to the queue. Only after the
7587 queue has been purged is it safe again to force the packet
7590 o If you send all packets immediately then it safe to send
7591 any of subsequent packets through the queue, however, after
7592 the first packet is put to queue then any subsequent packets
7593 must also be put to the queue.
7595 Follow these rules and everything works fine.
7597 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Added new function silc_server_remove_clients_by_server to
7600 remove all client entries from ID list when the server connection
7601 is lost. In this case it is also important to invalidate all
7602 client entires as they hold the invalid server entry. This
7603 fixes fatal bug when server has lost connection and will reconnect
7606 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7608 * Made some sanity checks to silc_server_daemonise like to check
7609 whether the requested user and group actually exists.
7611 * Added sanity check to SKE's silc_ske_responder_finish to check
7612 that the public and private key actually is valid.
7614 * Invalidate the client's nickname when receiving Replace ID
7615 packet and the Client ID is being replaced. This means that the
7616 server will query the nickname if someone needs it (client)
7619 * Sort the ID Cache in client library when the ID Cache data
7620 has changed (needs sorting).
7622 * Do not allow for SILC client to create several connections to
7623 several servers. The client does not support windows right now
7624 and generating multiple connections causes weird behaviour.
7626 Irssi-silc client does support windows and can handle several
7627 connections without problems, see: www.irssi.org and SILC plugin.
7629 * Fixed some places where client was added to the IDList. The
7630 rule of thumb is following (in order to get everything right):
7631 If the client is directly connected local client then the
7632 `connection' argument must be set and `router' argument must be
7633 NULL to silc_idlist_add_client function. If the client is not
7634 directly connected client then the `router' argument must
7635 bet set and the `connection' argument must be NULL to the
7636 silc_idlist_add_client function.
7638 * The funtion silc_server_packet_send_local_channel actually did
7639 not check whether the client was locally connected or not. It
7640 does that now. Fixed a bug related to LEAVE command.
7642 * Fixed Remove Channel User payload parsing bug in server's
7643 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7645 * The server's silc_server_save_channel_key now checks also the
7646 global ID list for the channel as it might not be in the local
7647 list. Fixed a bug related to LEAVE command.
7649 * Is this the end of the [<unknown>] buglet that has been lurking
7650 around for a long time? A little for loop fix in server's
7651 silc_server_command_whois_parse that is used by both IDENTIFY
7652 and WHOIS command. At least, this was a clear bug and a cause
7653 of one type of [<unknown>] buglet.
7655 * WHOIS and IDENTIFY commands call the function
7656 silc_server_command_[whois/identify]_check function even if
7657 we are not router server.
7659 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Added --with-gmp configuration option. If set the GMP
7662 is always compiled in the SILC source tree. If not set then
7663 it is checked whether the system has the GMP3 installed. If
7664 it has then the GMP won't be compiled (the system's headers
7665 and library is used), if it doesn't have it then the GMP is
7666 compiled in the SILC source tree.
7668 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7670 * Changed RSA private exponent generation to what PKCS #1
7671 suggests. We try to find the smallest possible d by doing
7672 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7673 not security fix but optimization.
7675 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Added new config entry [Identity] to fork the server and run
7678 it as specific user and group. A patch from Bostik.
7680 * Imported Dotconf configuration library into lib/dotconf.
7681 This will be used to create the SILC configuration files later.
7682 It will appear in the distsribution after this commit.
7684 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * A big code auditing weekend happening. Auditing code for
7687 obvious mistakes, bugs and errors. Also, removing any code
7690 Removed files for being obsolete:
7692 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7693 inline in the file lib/silcutil/silcbuffer.h)
7695 o lib/silcutil/silcbufutil.c (the header has inline versions)
7697 Changed code to fix possible error conditions:
7699 o The buffer formatting routines now check that the destination
7700 buffer really has enough space to add the data. This applies for
7701 both buffer formatting and unformatting
7702 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7703 unformatting was changed to accomodate following rules:
7704 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7705 sent to the function while XXX_*STRING will not allocate or copy
7706 the data into the buffer. Instead it sets the pointer from the
7707 buffer into the pointer sent as argument (XXX_*STRING used to
7708 require that the pointer must be allocated already). This change
7709 makes this whole thing a bit more consistent and more optimized
7710 (note that the data returned in the unformatting with XXX_*STRING
7711 must not be freed now). The routines return now -1 on error.
7713 o Tried to find all code that use buffer_format and buffer_unformat
7714 and added return value checking to prevent formatting and
7715 especially unformatting errors and possible subsequent fatal
7718 o Changed ske->x and ske->KEY to mallocated pointers in
7719 lib/silcske/silcske.h. Fixed possible data and memory leak.
7721 o Added return value checking to all *_parse* functions. Fixed
7722 many memory leaks as well.
7724 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7725 so that buffer overflows would not happen. All code now also
7726 checks the return value as it can fail.
7728 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Added reconnection support to server if the normal server looses
7731 its connection to the router (for example if router is rebooted).
7732 The server performs normal reconnection strategy implemented
7733 to the server. Affected file silcd/server.c.
7735 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Added new packet type SILC_PACKET_SET_MODE that is used to
7738 distribute the information about changed modes (for clients,
7739 channels and clients channel modes) to all routers in the
7740 network. Updated the protocol specification accordingly.
7742 Added functions into silcd/packet_send.c and
7743 silcd/packet_receive.c: silc_server_send_set_mode,
7744 silc_server_set_mode.
7746 Added new files silcmode.[ch] into lib/silccore that implements
7747 the encoding and decoding of Set Mode Payload. Added new type
7748 SilcSetModePayload. Moved the definitions of different modes
7749 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7751 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Oops, a little mistake in server's connection authentication
7754 protocol. The protocol is not ended with FAILURE but with
7755 SUCCESS if the authentication is Ok. :) Affected file is
7758 * Implemented NICK_CHANGE notify handling in server in the file
7759 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7760 the local clients on the channel. After the changing nickname
7761 in router environment snhould work and the [<unknown>] nickname
7762 should appear no more.
7764 The silc_server_replace_id function that receives the Replace ID
7765 payload now sends the NICK_CHANGE notify type also in the file
7766 silcd/packet_receive.c
7768 * Changed WHOIS and IDENTIFY command to support the maximum amount
7769 of arguments defined in protocol specs (3328 arguments). This
7770 fixed a bug that caused problems when there were more than three
7773 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7775 * Added extra parameter, command identifier, to the
7776 silc_client_send_command so that explicit command identifier
7779 Changed that ID list routines uses specific command identifier
7780 when sending WHOIS/IDENTIFY requests to the server so that they
7781 can be identified when the reply comes back.
7783 Affected files lib/silcclient/command.[ch],
7784 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7786 * Added `sender' argument to silc_server_packet_send_to_channel
7787 to indicaet the sender who originally sent the packet to us
7788 that we are now re-sending. Ignored if NULL. Affected file
7789 silcd/packet_send.[ch].
7791 * Added some server statistics support in silcd/server_internal.h
7792 SilcServerStatistics structure and around the server code. Also
7793 send some nice statistics information when client is connecting
7796 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7798 * Fixed channel ID decoding in server's JOIN command reply in
7799 silcd/command_reply.c
7801 * Fixed braodcasting of replace ID payload to not to send it if
7802 we are standalone server in silcd/packet_receive.c.
7804 * Fixed all channel message sending routines to not to send
7805 packets to clients that has router set, since they are routed
7806 separately in the same function earlier. Affects file
7807 silcd/packet_send.c and all channel packet sending functions.
7809 * In USERS reply, res_argv[i] are not allocated, the table
7810 is allocated. Thus changed that free the table, not its
7813 * In server's whois_check and identify_check if the client is
7814 locally connected do not send any WHOIS commands - they are not
7817 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Fixed some minor bugs in client when sending WHOIS command. The
7820 arguments was in wrong order.
7822 * Removed statis function add_to_channel from server in
7823 silcd/command.c that was previously used with the joining but
7826 * Tested USERS command in router environment successfully with two
7827 routers, two servers and two clients.
7829 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7831 * Reorganized the USERS command and command reply in client library
7832 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7833 When the command is given by user we register a pending command
7834 callback that will reprocess the command after the reply has been
7835 received from the server. When reprocessing the packet we then
7836 display the information. Thus, the USERS information is displayed
7837 now in the command callback instead of in the command reply
7838 callback. The processing of the command is same as previously
7839 when server has sent the command reply in the JOINing process.
7841 * Added to USERS command in silcd/command_reply.c to join the client,
7842 we didn't use to know about, to the channel after we've created
7843 a client entry for it. Also, for clienet we did know already still
7844 check whether it is on the channel or not and add it if not.
7846 * Removed silc_server_command_join_notify as the function and its
7849 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7851 * Changed the client's pending command handling to the same as the
7852 server's pending command handling. It is also now possible to
7853 execute command reply functions from other command reply
7854 function as the function callbacks for commands and command
7855 replies are one and same. The pending commands are not static
7856 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7857 in client connection context. Thus, pending commands are server
7858 connection specific as it is convenient.
7860 Changed the function silc_client_command_pending and
7861 silc_client_command_pending_del and added new function
7862 silc_client_command_pending_check. Removed the
7863 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7866 * Added cmd_ident, current command identifier, to the client
7867 connection context in lib/silcclient/client.h to keep track on
7868 command identifiers used in command sending. Client's command reply
7869 function handling now supports the mandatory command identifiers.
7871 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7872 funtions in client to fully support pending command callbacks.
7874 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7875 as one of the arguments to the application in the command reply
7878 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7879 before first releasing SILC but came back. Now it is removed again
7880 and should come back nomore. The FORWARDED flag was used only
7881 by the JOINing procedure by forwarding the command packet to router.
7882 Now, the JOINing procedure has been changed to more generic (due
7883 to various router environment issues) and FORWARDED is not needed
7884 anymore for anything. The protocol specification is yet to be
7887 Now, removed silc_server_packet_forward from server and the flag
7888 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7890 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7892 * Renamed NAMES command to USERS command. The NAMES was named that
7893 due to historical reasons. Now it is renamed. Also, rewrote
7894 parts of the USERS command. The nickname list is not sent anymore
7895 by the server. Only Client ID and mode lists are sent in the USERS
7896 command. Changed this also to the protocol specification.
7898 The client now resolves the names and stuff after it receives
7899 the USERS list from the server when joining to the channel.
7901 * WHOIS and IDENTIFY commands has been changed to support multiple
7902 Client ID's per command. One can now search for multiple users
7903 in the network by sending only one WHOIS or IDENTIFY command.
7904 Changed the code and the protocol specifications.
7906 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7907 uses silc_server_command_whois_parse to parse the request. */
7909 * If normal server, do not parse the WHOIS and IDENTIFY requests
7910 before sending it to the router. Saves some time.
7912 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7914 * Fixed JOIN command on client library. Wrong number of arguments
7915 used to crash the client.
7917 * Added silc_server_channel_has_global function to check whether
7918 channel has global users or not.
7920 * Added silc_server_channel_has_local function to check whether channel
7921 has locally connected clients on the channel.
7923 * The silc_server_remove_from_one_channel now checks whether the
7924 channel has global users or not after given client was removed from
7925 the channel. It also checks whether the channel has local clients
7926 on the channel anymore. If it does not have then the channel entry
7927 is removed as it is not needed anymore.
7929 * The silc_server_notify now checks on JOIN notify whether the joining
7930 client is one of locally connected or global. If it is global then
7931 the channel has now global users on the channel and that is marked
7932 to the channel entry. Also, it now saves the global client to
7933 global list who is joining and JOINs it to the channel. This is
7934 for normal server, that is.
7936 Changed silc_server_send_notify_on_channel,
7937 silc_server_packet_relay_to_channel and
7938 silc_server_packet_send_to_channel check if we are normal server
7939 and client has router set (ie. global client) do not send the
7940 message to that client, as it is already routed to our router.
7942 * Implemented LEAVE notify type handling in silc_server_notify
7945 * Tested LEAVE command in router environment successfully. Tested
7946 with two routers, two servers and two clients.
7950 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7952 * Implemented SIGNOFF notify type handling in silc_server_notify
7955 * silc_server_remove_id now removes the client entry from all channels
7956 it has joined and thusly sends SIGNOFF notify type.
7958 * Rewrote the NAMES list generation in server by removing two excess
7959 loops. The lists are created now inside one loop.
7961 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * silc_server_remove_channel_user checks now also global list
7964 for channel and client.
7966 * silc_server_new_channel_user checks now both local and global
7967 list for channel and client. Fixed a bug in client id decoding.
7968 Used to decode wrong buffer.
7970 * silc_server_channel_message checks now both local and global
7971 list for channel entry.
7973 * Tested channel joining (hence JOIN) in router environment
7974 successfully. Tested with two routers, two servers and two
7977 * Tested channel message sending in router environment successfully.
7979 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7981 * Added silc_server_save_channel_key into server.[ch] to save the
7982 received channel key in Channel Key payload processing. It is
7983 also used in JOIN command reply handling.
7985 Equivalent function silc_client_save_channel_key added into
7986 client.[ch] into client library.
7988 * Changed JOIN command reply to send information whether the channel
7989 was created or not (is existing already) and the channel key
7990 payload. Changed protocol specs accordingly.
7992 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7993 the request was sent by ID and not by nickname. Crashed on
7996 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7998 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7999 now correctly save the received data.
8001 * silc_server_free_sock_user_data now notifies routers in the
8002 network about entities leaving the network.
8004 At the same time implemented functions silc_server_remove_id
8005 and silc_server_send_remove_id to receive and send REMOVE_ID
8006 packets. The packet is used to notify routers in the network
8007 about leaving entities. The ID removed will become invalid in
8010 * Added function silc_idlist_del_server into server. Removes and
8011 free's server entry from ID list.
8013 * silc_server_private_message function now checks, if we are router,
8014 that the destination ID really is valid ID, naturally.
8016 * In router when NEW_ID packet is received (for new client) the
8017 hash of the Client ID is saved in the ID Cache but the
8018 client->nickname is set to NULL, instead of putting the hash
8021 IDENTIFY command now also checks that client->nickname must be
8022 valid. If it is not if will request the data from the server who
8023 owns the client. Added new function
8024 silc_server_command_identify_check.
8026 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8027 to set the command to already allocated Command Payload.
8029 * Tested private message sending in router environment with two
8030 routers, two servers and two clients. Fixed minor bugs and now
8033 * Fixed segfault from client's NAMES command. Used to crash if
8036 * Forwarded packets must not be routed even if it is not destined
8037 to the receiver. Changed server code comply with this.
8039 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Added `require_reverse_mapping' boolean value to ServerParams
8042 structure. If TRUE (not default) the server will require that
8043 the connecting host has fully qualified domain name.
8045 If the reverse mapping is not required and hostname could not be
8046 found the IP address is used as hostname.
8048 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8050 * Implemented version string checking to both client and server.
8051 The check is incomplete currently due to the abnormal version
8052 strings used in development version of SILC.
8054 * Changed all command functions in server to use the new
8057 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8059 * Changed char *data to unsigned char *data in ID Cache system to
8060 support binary data as ID Cache data. Changed code to support
8061 binary data in lib/silccore/idcache.c.
8063 * Renamed silc_server_packet_relay_command_reply to
8064 silc_server_command_reply as it is normal packet receiving
8065 function. Rewrote the function to accept command replys for
8066 servers and not only for clients.
8068 * Mark remote router always as registered server if we are connecting
8069 to it. Otherwise, commands sent by the router to us are ignored.
8071 * All ID List find routines now returns the ID Cache Entry pointer
8072 as well if requested.
8074 * WHOIS command works now in router environment, tested with two
8075 routers, two servers and two clients.
8077 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8078 in router environment (as it is almost equivalent to WHOIS) but
8079 hasn't been tested thoroughly. Added new functions:
8081 silc_server_command_identify_parse
8082 silc_server_command_identify_send_reply
8083 silc_server_command_identify_from_client
8084 silc_server_command_identify_from_server
8086 * Disabled route cache adding because adding two different ID's with
8087 same IP replaces the old cache entry thus giving wrong route.
8088 The entry->router->connection is always the fastest route anyway
8089 so route cache may not be needed. Of course, new routes maybe
8090 established after receiving the ID when the entry->router->connection
8091 might not be anymore the most optimal.
8093 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8095 * Add route cache for received ID for fast routing.
8097 * Added silc_server_packet_route to route received packet on router
8098 that is not destined to us.
8100 * Renamed silc_server_get_route to silc_server_route_get.
8102 * Added id_string and id_string_len fields into SilcServer to
8103 include encoded ServerID for fast comparing without excess
8104 encoding of the ID's.
8106 * Cleaned up WHOIS command on server side. Added following static
8109 silc_server_command_whois_parse
8110 silc_server_command_whois_check
8111 silc_server_command_whois_send_reply
8112 silc_server_command_whois_from_client
8113 silc_server_command_whois_from_server
8115 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8116 arguments in command replies. All command functions should be
8117 updated to use this macro.
8119 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * Minor typo fixes on command reply handling on server.
8123 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Added silc_server_command_add_to_channel internal routine to add
8126 the client to the channel after router has created the channel and
8127 sent command reply to the server.
8129 * Added generic silc_server_send_command to send any command from
8132 * Use static buffer with ID rendering instead of duplicating data.
8134 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8136 * Fixed a channel user mode bug when joining to a channel server gave
8137 everybody channel founder rights, oops.
8139 * We mark ourselves as the router of the incoming server connection
8140 if we are router ourselves. This way we can check in some packet
8141 sending functions whether it is locally connected server. For
8142 incoming router connections we put NULL.
8144 * For router sending packets locally means now always sending the
8145 packet cell wide; to local clients and local servers. For normal
8146 server sending packet locally means sending it to only local
8149 * Fixed the JOIN command to really work in router environment. If the
8150 channel is created it is always created by the router. Router is
8151 also responsible of making the initial joining to the channel,
8152 sending JOIN notify to the sending server and distributing
8153 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8154 does not exist server doesn't do anything else but forward the
8155 command to the router which performs everything.
8157 * Added silc_server_send_channel_key function to send the Channel Key
8160 * Added silc_server_create_channel_key to create new channel key. The
8161 channel key is now re-generated everytime someone joins or leaves
8162 a channel, as protocol dictates. Note: channel->key_len is the
8165 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8168 packet_receive.[ch] to separate packet sending and receiving
8169 routines. The server.[ch] now includes everything else including
8170 actual packet processing (writing and reading data) and other
8173 Renamed silc_server_private_message_send_internal to
8174 silc_server_send_private_message. The routine is still though
8175 used only to relay private messages as server does not send
8176 private messages itself.
8178 Renamed silc_server_new_channel to silc_server_create_new_channel
8179 and added new function sicl_server_new_channel that handles the
8180 incoming New Channel packet. Added also new sending function
8181 silc_server_send_new_channel to send New Channel Payload.
8183 * Added new function silc_server_notify to process incoming notify
8184 packet to the server/router. Server may then relay the notify
8185 to clients if needed.
8187 * Added new function silc_server_new_channel_user to process incoming
8188 New Channel User packet. Router will redistribute the packet and
8189 send JOIN notify to its local clients and locally connected servers
8190 if needed. Normal server will send JOIN notify to its local client
8191 on same channel when received this packet. Added also corresponding
8192 sending function silc_server_send_new_channel_user to sent the
8195 * Added boolean route argument to send_notif_to_channel and
8196 packet_send_to_channel functions to attempt to route the packet
8197 if it is TRUE and send only locally if it is FALSE.
8199 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * silc_server_replace_id now broadcasts the received replace ID
8202 packet if it is not broadcast packet already. The router must
8203 broadcast to inform other routers about changed ID.
8205 * Added backpointer to server's router into SilcServer context in
8206 silcd/server_internal.h.
8208 * Fixed silc_server_packet_broadcast to send correct broadcast
8211 * The channel key is now distributed to the local client as soon
8212 as it is received from the router (in router environment) so that
8213 no other packet may be sent for the channel until client has
8216 * silc_server_remove_channel_user now broadcasts the received
8217 Remove Channel User packet if it is not broadcast packet already.
8218 The router must broadcast to inform other routers about removed
8221 * Added users field into SilcPacketContext that is a reference count
8222 of the context. One can increase the reference count by calling
8223 silc_packet_context_dup which is now changed to just increase the
8224 reference count instead of duplicating the data. The reference
8225 count is decresed by calling silc_packet_context_free that will
8226 free the data after the reference count hits zero.
8228 For now on the packet context and everything allocated into it
8229 (including the raw packet from network) must be freed by calling
8230 the new silc_packet_context_free function. Added also new function
8231 silc_packet_context_alloc that must be used now to allocate the
8232 context. This also means that if a routine is asynchronous from
8233 silc_[client/server]_packet_parse_type the packet context must
8234 be duplicated by calling silc_packet_context_dup. Otherwise it
8235 gets free'd after silc_[client/server]_packet_parse_type returns.
8236 Also, one must remember that if packet is duplicated then its
8237 reference count must be decresed by calling the free function as
8238 many times as it was duplicated.
8240 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8241 from both client and server.
8243 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Made joining to a channel working in router environment.
8247 * Cleaned up JOIN command on server side and create function
8248 silc_server_command_join_channel internal routine to make the
8251 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8253 * Changed silc_command_pending list to SilcDList. Also, added
8254 `ident' field to SilcServerCommandPending structure to identify
8255 the reply and to call correct callback.
8257 Added silc_server_command_pending_check function to replace the
8258 corresnponding macro. The silc_command_pending list is not
8261 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8262 to set identifier to previously allocated Command Payload. It
8263 is used to set identifier for command when resending Command
8266 * Added silc_command_payload_encode_payload to encode Command
8267 Payload buffer from SilcCommandPayload structure.
8269 * Added silc_argument_payload_encode_payload to encode Argument
8270 payload buffer from SilcArgumentPayload structure.
8272 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Changed WHOIS command to support router connection on server side.
8275 The whois request is always sent to router unless the server is
8276 standalone server. After server has received the reply from the
8277 router will it send the reply to the client.
8279 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8280 broadcast received broadcast packet. The function is used only
8281 by router. The broadcast packet is always sent to the router's
8284 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8285 render given ID to printable string, for log files for example.
8287 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Made basic router to router connections working. At least they
8290 can now connect to each other but nothing really works the way
8291 they are supposed - yet.
8293 * Added new initiator token to RouterConnection configuration
8294 file in silcd/serverconfig.[ch]. It is used to tell whether we
8295 are the initiator to the remote router or whether we'll expect
8296 the other end to connect.
8298 * Moved registering of listener task to silc_server_init, hence
8299 the server starts listenning as soon as it is run, even if it
8300 does not have connections to other routers. Let's see how well
8303 * Changed default connection retry timeouts for more suitable in
8306 * Removed cipher and such arguments from silc_idlist_add_client
8307 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8308 Added new function silc_idlist_add_data to add the keys and stuff
8311 * Added SilcIDListData structure and added it to SilcClientEntry
8312 and SilcServerEntry as their first field in the structure. This
8313 way we can explicitly cast the ID entries to the SilcIDListData
8314 structure and get common data for the entries. In past, we had
8315 to first check what type of connection it is and then cast it to
8316 correct ID entry type. Now, we can directly cast the opaque
8317 pointer to the SilcIDListData (no matter what ID entry it actually
8318 is) and get the data needed.
8320 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8322 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8323 in some circumstances even if threre were timeout tasks, though not
8324 IO tasks, but tasks anyway. Now fixed.
8326 * Defined SilcServerConnection structure to hold connection specific
8327 stuff about directly connected servers and routers. The definition
8328 is currently in silcd/server_internal.h. I thought about having
8329 a bit more important role fro this struct but for now it is used
8330 only when connecting to other server (or router actually).
8332 * Added connecting retry support in server when connecting to
8333 router(s). The retry feature implement exponential backoff
8334 algorithm. Also, added SilcServerParams structure to hold default
8335 parameters for server. For now, it include these retry settings
8336 and are hard coded. After server is moded to be as Silc Server
8337 Library this structure will be more important.
8339 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8341 * Changed client librarys channel->clients table to SilcList and
8342 changed code accordingly.
8344 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8346 * Changed client's channel table to SilcList and changed code
8347 accordingly. Also changed SilcChannelClientEntry to include back-
8348 pointer to the channel so that client entry can use that structure
8349 as list as well and we have fast cross-reference to the channel.
8350 This change dramatically decreased the complexity of channel
8351 handling with client entry and vice versa (removed one extra
8352 loop when searching for channel entry from many functions).
8354 * Changed server->sim from table to SilcDList and changed code
8357 * NAMES command can now be used from user interface. It will show
8358 the user list on the channel, neatly.
8360 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8361 Code now saves realname of the user if it becomes available.
8363 * Renamed configure.in to configure.in.pre and made ./prepare
8364 script to automatically add correct version string to
8365 configure.in which it creates from configure.in.pre.
8367 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8369 * NAMES command reply now shows users mode with the nickname when
8372 * Moved silc_client_ch[u]mode[_char] functions from
8373 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8374 place sucks, they are utility functions and should be in some
8377 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8379 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8382 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added TRQ (efficient deque and list library) into lib/trq. This is
8387 a very good list library that is currently used in the SILC. Defined
8388 SilcList API over the library because I didn't like the API very
8389 much. See lib/trq/silclist.h for the API and examples of how to
8390 use the API. Fixed various places in the code to use the new
8391 SilcList API. The SilcList is meant for lists that has a structure
8392 already defined as a list. It is not suitable to add just some
8393 context to the list (in TRQ, the context is the list actually).
8395 So, I defined SilcDList that can be used for the purpose where
8396 predefined list structure does not exit. This can be used as
8397 such list. Now some context just can be added to the SilcDList.
8398 Currently this list is not used in the SILC just yet, though there
8399 are a lot places where this can replace dynamically allocated
8400 tables and I will fix these places, later, to use SilcDList.
8401 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8402 and use TRQ internally).
8404 Also fixed some annoying warning messages that the original TRQ
8405 code generated. Also minor changes to TRQ's Makefile.in.
8407 * Added support for querying by Client ID to both WHOIS and
8408 IDENTIFY commands into server, as required by the protocol.
8410 * Removed method function pointers from SilcBuffer structure. They
8411 weren't used to anything and just increased the context size for
8412 no good reason. This change also made silc_buffer_alloc and
8413 silc_buffer_free functions inline functions.
8415 * Disabled command flooding detection support until it's fixed so
8416 that it accepts commands in but does not execute them more than once
8419 * Added silc_net_localhost(), to return local hostname, into
8420 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8421 that must be initialized before calling silc_client_init.
8423 * Added new function: silc_server_send_notify_on_channels to send
8424 notify messages to all channels client has joined. It is assured
8425 that the message is sent only once per client.
8427 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8428 lib/silcutil/silcutil.[ch] as silc_format function. The new
8429 function is generic and is used by server as well, not only by
8430 the logging routines.
8432 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8433 the provided version string was not acceptable. Added new function:
8434 silc_ske_check_version into lib/silcske/silcske.h. The function
8435 must be implemented by the application (client or server) and it
8436 does not reside in the SKE library. The function checks the version
8437 string remote end sent.
8439 * Added back pointers (to opaque context and to SilcSocketConnection)
8440 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8442 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8443 duplicate packet context structure.
8445 * Changed `notify' client operation to send same arguments as client
8446 receives from server except for ID's. ID's are mapped to correct
8447 ID entry and that is returned. Also, if channel entry is not sent
8448 by server but the notify is for channel the channel entry is sent
8449 to application (otherwise application doesn't know that it is for
8450 channel (library gets it from packet's Destination ID)).
8452 * Added silc_client_remove_from_channels into client library to
8453 remove a client from all channels it has joined to. Used when
8454 received SIGNOFF notify from server. Added also new function
8455 silc_client_replace_from_channels to replace old ID entry with
8456 new ID entry on all channels. Used when received NICK_CHANGE
8459 * Fixed ID Cache list handling in silc_idlist_get_client in
8460 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8461 to get (or query) client by ID.
8463 * Updated TODO list.
8465 * Added connection authentication status message defined by the
8466 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8467 support for these into the code in client and server side.
8469 * Added generic function silc_client_send_command to send any command
8470 with variable argument list. Application should use this function
8471 to send commands if the command functions provided by the library
8472 does not suite for the application's user interface needs.
8474 * Added new `failure' client operation. Application is notified about
8475 received failure packet if client is executing a protocol. In this
8476 case the protocol's execution has failed.
8478 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8479 is required by the protocol.
8481 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8482 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8485 * Added status flag to SilcSKE object to indicate realtime status
8486 of the SKE protocol.
8488 * Application receives now exactly same command reply arguments as
8489 the library receives from server. However, if ID is received the
8490 corresponding ID entry is returned to the application (eg. Client
8491 ID is mapped to correct SilcClientEntry entry and that is returned).
8492 Changed command_reply client operation due to this change.
8494 * Changed all ID's in commands and in command replys as ID Payloads.
8495 Change affected both client and server side codes.
8497 All ID's sent in SILC network (with execption of ID's in SILC
8498 Packet header) are sent in ID Payload to support variable length
8501 * Server now notifies nick changes and notifies all clients on
8502 the channels about the new nickname (about the new Client ID,
8505 * Implemented CMODE command to change channel modes. Supports all
8506 channel modes defined by the protocol specs except ban and invite
8507 lists. (Also, private channel key mode is supported but support for
8508 setting private channel key in client is missing, thus, this mode
8509 has no effect on client side (except that server requires that the
8510 client uses private channel key and normal channel traffic does not
8513 Also, invite mode works per se, but INVITE command does not work
8514 yet correctly, so you can set channel as invite only channel but
8515 inviting clients to the channel does not work (it is yet to be
8516 thought what's the best way to do it).
8518 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8519 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8520 Implemented CUMODE command to change user's mode on the channel.
8521 Supports all modes defined by the protocol specs.
8523 * Added NAMES command reply to return users modes on the channel.
8525 * Removed unnecessary and slow ciphers from lib/silccrypt.
8527 * Set SO_KEEPALIVE option to connection sockets by default.
8529 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8531 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8532 redefined the Notify Payload into protocol specs.
8534 * Added silc_id_payload_parse_id to get ID directly from raw
8537 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8539 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8540 accept searching by Client ID as well.
8542 * Added support for LEAVE and SIGNOFF notify types in client library.
8544 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8545 to parse ID Payload from raw data.
8547 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8549 * Added flags parameter into silc_ske_assemble_security_properties
8550 function in lib/silcske/silcske.[ch].
8552 * Changed notify client operation to fit better for notify messages
8553 sent by server. The notify payload received from server is now
8554 passed to the application (after parsing it to SilcNotifyPayload).
8555 It is application's responsibility to retrieve the arguments
8556 from the payload and show the message the way it wants. The message
8557 sent by server is implementation specific.
8559 * Changed public keys to comply with the protocol specification.
8560 Old public keys are not supported anymore and are not compatible.
8562 * Removed nickname from Channel Payload as the latest draft removed
8563 it. The client must resolve the nickname from the NAMES command
8564 reply received when it joined the channel.
8566 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8568 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8570 * Fixed some errors in protocol specification drafts.
8572 * Created lib/silccore/silcnotify.c to implement Notify Payload
8573 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8574 generic payloads described by protocol specifications. The file
8575 includes implementations for ID Payload and Argument Payload.
8577 * Changed Command Payload implementation to use the new Argument
8578 Payload. Changed command_xxxx_payload to command_payload_xxxx
8579 to comply with SILC coding conventions.
8581 * Added suppport for Argument Payload handling in Notify Payload
8582 implementation as protocol requires it. Added the new support
8583 into server and client lib as well.
8585 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8587 * Added support for multiple nicknames on same channel. [n] is
8588 added locally to the nickname if there are more than one same
8589 nicknames on the channel.
8591 * Server now sends all nicknames that matched WHOIS request.
8592 Client also shows the list received from server.
8594 * Added TOPIC command to client side. User can now set and show
8595 current topic on channel.
8597 * Added MOTD command to client and server. Also, server sends the
8598 motd when client connects to the server.
8600 * Changed version strings to comply ISO 8601.
8602 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8604 * Fixed protocol error handling in client library. It should now
8605 cope even if the SKE fails for some reason.
8607 * Made new protocol specification drafts for submitting to IETF.
8609 * Implemented TOPIC command to server in silcd/command.c.
8611 * Added two new notify types into lib/silccore/silcnotify.h:
8612 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8613 notify nickname change and topic setting/change on a channel.
8615 * API change of command_reply operation in client library. The
8616 application gets now the status type received from server as well.
8618 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8620 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8622 * Cras fixed and optimized the packet handling even further and
8623 it should work now. Minor change to the prototype of function
8624 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8626 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8628 * Added new function into lib/silcutil/silcschedule.[ch]:
8629 silc_schedule_with_fd to select() a specified fd. The function
8630 returns after timeout expires or data arrives or goes. The
8631 function is used by packet routines to wait that all data is
8632 received from network.
8634 * Fixed data reading from network in lib/silccore/silcpacket.c.
8635 The code now assures that all data is read from the fd and then
8636 continues packet processing. This was a bug fix since the code
8637 used to drop some data in some circumstances.
8639 * Added new function into lib/silcclient/client.[ch]:
8640 silc_client_start_key_exchange to start key exchange after
8641 connection has been established to server. The code internally
8642 now uses this funtion but its main purpose was to provide it
8643 for applications that perform their own connecting. After
8644 application has created a connection it merely calls this
8645 function to start the key exchange between client and server.
8646 The library takes care of everything else after that.
8648 Updated also lib/silcclient/README to explain the usage of
8651 * Do not send to application information that connection has
8652 been established. Application gets notified it by connect
8655 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8657 * Applied cras's patch to add silc_schedule_one function. The
8658 function runs scheduler once and returns.
8660 * Fixed the scheduler after cras messed it up. The timeout
8661 handling works now as it's supposed to work.
8663 * Added into lib/silccore/ silcnotify.h to include notify
8664 message types support. Changed silc_server_send_notify*
8665 functions, in server.[ch], to support those new notify types.
8666 Added the support for the notify types into client library,
8667 as well. Added new notify client operation into ops.h in
8670 * Changed silc_server_packet_send_to_channel to send normal
8671 packets instead of just channel message packets. The function
8672 is now used to send the notify packets to channels. It is not
8673 used to send channel message packets anymore, as server never
8676 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8677 va_arg()s as it seems to require it nowadays. I guess, if SILC
8678 is compiled with older va_arg() the new code should work anyway.
8680 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8682 * Splitted core library. Core library (lib/silccore) includes
8683 now only SILC protocol specific core (and common) components.
8684 Created new utility library (lib/silcutil) that includes more
8685 generic purpose stuff. The stuff for util library was taken
8686 from the old core library. This was minor and easy split.
8688 * Created SILC Client Library (lib/silcclient) that includes
8689 implementation of the SILC client without user interface. This
8690 was major move from silc/ directory. The code has been changed
8691 so that it is transparent towards the user interface. The
8692 silc/ directory includes now the same user interface as before
8693 and it uses the new client library. Read lib/silcclient/README.
8694 Basicly, the client library performs everything else related
8695 to SILC except user interface handling. Also, configuration
8696 files are considered to be part of user interface and library
8697 does not handle them.
8699 This change also changed a lot of structures, function naming etc.
8700 Most important change was that SilcClientWindow object was
8701 renamed to SilcClientConnection in the client library. Created
8702 also new file lib/silcclient/ops.h. Also added new files
8703 silc/local_command.[ch] and silc/client_ops.[ch].
8705 All these changes were made to make it easier for user interface
8706 designers to create what ever user interface for the SILC client
8709 It is also expected that the server will be moved to lib
8710 directory as well and SILC Server Library will be created;
8711 sometimes in the future.
8713 * Removed Local commands from lib/silccore/silccommand.h as
8714 they are application specific and new client library does not
8715 handle any of those anymore.
8717 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8718 old client implementation in silc/.
8720 * Added support for callback functions in SILC_LOG_* macros.
8721 Application can now set its own callbacks that will be called
8722 instead of using the default functions that will always print
8723 the debug messages to stderr (or stdout). Also, debugging can
8724 now be disabled by setting silc_debug to FALSE and re-enabled by
8725 setting it to TRUE. Note, that logging will still work even
8726 if debugging is disabled.
8728 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8729 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8730 silc_log_reset_debug_callbacks.
8732 * To enable debugging in silc client one must give now -d
8733 option on command line.
8735 * Changed silc_schedule_init to automatically allocate task queues
8736 if they are not allocated before calling it.
8738 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8740 * Added GMP 3.1 into math library.
8742 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8744 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8745 a channel in SILC network. The packet is used by servers and
8746 routers to notify other routers that user has left a channel.
8747 This little feature was missing until now. Added the feature
8748 to protocol specification as well.
8750 Added functions: silc_server_send_remove_channel_user and
8751 silc_server_remove_channel_user into server.[ch].
8753 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8754 lib/silccore/silcpacket.h. However, they are not implemented
8757 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8759 * Fixed joining to a channel and sending channel messages
8760 between server and router. The channel message sending should
8761 now work inside a cell.
8763 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8765 * Fixed the private message sending between server and router.
8766 The private message sending should now work inside a cell.
8768 * Added silc_server_replace_id into server.[ch] to replace
8769 existing ID in the SILC network.
8771 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8772 and silc_idlist_replace_server_id into idlist.[ch] in server.
8774 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8776 * Fixed the server to server connections. Server can again now
8777 connect to router. Router to router connections probably does
8780 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8782 * Added dynamic protocol registering support. Now protocols can
8783 registered and unregistered on the fly. Patch by cras.
8785 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8787 * Added lib/contrib directory to hold routines that some platforms
8788 don't have but are needed by SILC.
8790 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8791 into lin/contrib to provide getopt() and getopt_long() for
8792 those who don't have it.
8794 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8796 * Added AWAY command to client. When away message is set and
8797 client receives a private message packet the client automatically
8798 replies to the sender with the away message.
8800 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8801 bug seemed to be the cause of recent problems when compiling
8804 * Added version detection support to SKE protocol specification
8805 and added the new changes to the SKE implementation as well.
8806 There were other minor changes in the SKE protocol as well.
8808 Many changes in lib/silcske/silcske.[ch] and in
8809 lib/silcske/payload.[ch].
8811 * Added ^U functionality, clear input line. Patch from cras.
8813 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8815 * Mainly small bugfixes on core library. Fixed some debugging
8816 logging and buffer overflow in silclog.c.
8818 * Updated config.sub and config.guess on the distribution tree.
8820 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8822 * Added command lagging support in server. Client may execute
8823 commands now only once in two seconds.
8825 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8827 * Optimized packet reception. MAC computation and checking is now
8828 also more optimized. A lot previously duplicated code is now
8829 used as generic by both client and server.
8831 * Fixed key pair generation in clientutil.c
8833 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8835 * Added into lib/silccore/silcbufutil.[ch] new function;
8836 silc_buffer_realloc.
8838 * Moved generic packet sending/encryption functions to
8839 lib/silccore/silcpacket.[ch] from client and server. Some
8840 rewriting of the functions.
8842 * Moved all generic packet reception/decryption functions to
8843 lib/silccore/silcpacket.[ch] from client and server. The
8844 packet processing is now much cleaner in both client and server.
8845 These were major changes in both client and server.
8847 * Created many common functions in server to do packet sending.
8848 Previously code were duplicated a lot, this has been removed
8851 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8853 * Rewrote major parts of the ID cache system. Don't know
8854 whether it is better now or not but at least the API is more
8857 * Major rewrite on ID cache stuff on client because of the ID
8858 cache API changes. Added idlist.c to client.
8860 * Also major rewrite on ID cache stuff on server as well.
8861 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8862 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8863 in hand, instead they are all put into the ID cache system now.
8864 All server_idlist_* routines uses ID cache now instead of
8865 traversing its own lists (those lists does not exist anymore).
8866 SilcIDList though still exists. Also, SilcXXXEntry's are
8869 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8871 * Finally made the SKE implementation compliant to the protocol
8872 specification. All mp integers are now binary encoded as
8873 opposed being HEX encoded.
8875 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8878 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8879 functions: silc_[encode/decode]_pem. Also added function
8880 silc_encode_pem_file to PEM encode with newlines ('\n') for
8883 * SILC public keys are now encoded either PEM or binary. Same
8884 option is for private keys as well. By default private keys
8885 are binary encoded and public keys PEM encoded. Silly HEX
8886 encoding were removed.
8888 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8889 function to create fingerprints.
8891 * Fixed a bug in SHA1; does not change the original data anymore.
8893 * Partly implemented INFO command on client and server side.
8894 Fixed CLEAR command. Changes to SERVER command; show current
8895 server(s) when giving command without arguments. Added
8896 VERSION command to client.
8898 * Added check to server that unregistered connections cannot
8899 execute commands (unless it is specificly allowed).
8901 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8903 * Fixed screen refresh.
8905 * Fixed channel joining bug from client. On some circumstances
8906 client tried to join to a channel it had already joined.
8908 * Added public key verification process into client's protocol.c.
8909 The client now verifies the public key from user and saves
8910 it into ~./silc/serverkeys/ directory.
8912 Added into: clientutil.[ch]: silc_client_verify_server_key.
8914 * Changed SKE protocol's silc_ske_initiator_finish function
8915 to accept callback function that verifies the received public
8916 key. Removed old silc_ske_verify_public_key function.
8918 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8920 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8921 silc_pkcs_private_key[_data]_set.
8923 * Made the password and public authentication more cleaner in
8924 server's protocol.c.
8926 * Removed historic and obsolete protocol `channel_auth' from
8927 both client and server.
8929 * Removed wrong way of sending command status messages from
8930 server to client in server's command.c. The old way violated
8931 protocol specification.
8933 Changes to silccore/silccommand.[ch]: removed
8934 silc_command_encode_status_payload -> not needed anymore,
8935 changed silc_command_encode_payload_va to accept extra
8936 argument on variable argument list. The argument type must
8937 now be provided to the function. Also, added new function:
8938 silc_command_encode_reply_payload_va which is same as
8939 normal command_encode_payload_va except command status type
8940 is provided as extra argument.
8942 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8944 * Added ~./silc directory handling. The directory includes the
8945 public and private keys for the client.
8947 Added silc_client_check_silc_dir, silc_client_create_identifier
8948 and silc_client_load_keys.
8950 * Implemented SILC protocol compliant public key. Added public
8951 and private key saving to and loading from files.
8953 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8954 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8955 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8956 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8957 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8959 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8960 silc_pkcs_load_[public/private]_key.
8962 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8964 * Added silc_server_get_route (route.[ch]) to get connection
8965 data for the fastest route for given ID.
8967 * Implemented INVITE command on client and server. The command
8968 were re-defined in the SILC Protocol Specification and the
8969 implementation now complies with the specification.
8971 * Implemented PING command on client and server.
8973 * Implemented NAMES command on client and server. The server side
8974 supports currently only normal server not router server yet.
8975 Some changes to NAMES definition in SILC protocol specification.
8977 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8979 * Implemented LEAVE command on client and server.
8981 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8982 again. This change was made to the protocol as well. Server
8983 should not violate the protocol specification anymore.
8985 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8987 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8988 was tested. SOCKS4 was not but should work anyway.
