3 * Added new configuration options and blocks:
4 keepalive_secs, reconnect_count, reconnect_interval,
5 reconnect_interval_max, reconnect_keep_trying and
6 require_reverser_lookup. Added ConnectionParam block, and
7 implemented the connection parameters when connecting as
8 initiator and when accepting connections as responder.
10 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
11 whether given configuration value has been given already.
13 Affected files silcd/serverconfig.[c], server.[c].
15 * Splitted the doc/example_silcd.conf.in. Separated the crypto
16 algorithm parts and created new file silcalgs.conf, that
17 is now included from the example_silcd.conf.in.
19 * Optimized the silc_server_connect_to_router_second to take
20 the connection configuration object from the SilcServerConnection
21 object instead of finding it during the connecting phase.
22 Added the configuration object to SilcServerConnection struct.
23 Affected files silcd/server_internal.h, server.c.
25 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Add the client on channel after it was resolved at the
28 channel message receiving, and it was not already on the
29 channel. Affected file lib/silcclient/client_channel.c.
31 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Fixed the public key authentication to allocate always the
34 destination signature buffer instead of using static buffer.
35 Affected file silcd/protocol.c.
37 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
39 * Unified the serverconfig.[ch]'s helper function interface.
40 Affected file silcd/serverconfig.[ch].
42 * Removed doc/example_silc.conf.in since it is redundant.
43 The make install will now install irssi/silc.conf file.
45 * Added new Passphrase and Publickey authentication methods to
46 config file, allowing both public key and passphrase based
47 authentication to be set at the same time.
49 Added `prefer_passphrase_auth' setting in config file which
50 can be used to set to prefer passwd auth if both passwd and
51 public key is set. If not set, public key is preferred.
52 This has effect only when being initiator (responder will try
55 Added support for authentication with passphrase and public key
56 at the same time. The passphrase is tried first always since
57 it is faster to check.
59 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
61 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
63 * Merged the new SILC Config library, with the server parsing
64 support. Read the header file silcconfig.h or the toolkit
65 documentation for the news. Affected files are
66 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

95 as part of Toolkit documentation.
97 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Fixed CUMODE_CHANGE notify handling to change the mode of
100 correct client. Affected file lib/silcclient/client_notify.c.
102 * Make silc_rng_alloc fail if it cannot allocate the sha1
103 hash algorithm. Affected file lib/silccrypt/silcrng.c.
105 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
107 * Fixed the file transfer's key agreement payload to include
108 zero port also if the hostname is NULL because it could not
111 Call file transfer monitor callback now also if error occurs
112 during key agreement protocol.
114 Changed the silc_client_file_send interface to return the
115 SilcClientFileError instead of session id. The session ID
116 is returned into pointer provided as argument.
118 Check that the file exists locally before sending the
119 file transfer request at all.
121 Affected file lib/silcclient/client_ftp.c, silcapi.h.
123 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
124 error than can occur while key agreement protocol. Affected
125 file lib/silcclient/silcapi.h.

128 is changed and +k mode is set in the channel. Affected file
129 irssi/src/silc/core/silc-channels.c.
131 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
132 SILC_LOG_WARNING to give out Warning and not Error. Affected
133 file lib/silcutil/silclog.c.
135 * Fixed the channel message payload decryption in the function
136 silc_channel_message_payload_decrypt to not modify the original
137 buffer before it is verified that the message decrypted
138 correctly. Otherwise, next time it is called with correct
139 channel key it won't encrypt since the payload is corrupted.
140 Affected file lib/silccore/silcchannel.c.
142 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
144 * Do not constantly resize the window. A fix patch by cras.

152 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
154 * Fixed a bug in hash table internal routine for traversing
155 the table with foreach callback. The current entry may
156 become invalid in the callback but it was referenced after
157 the callback returned.
159 Do not allow auto rehashing of hash table during the
160 silc_hash_table_foreach operation, for same reasons as it is
161 not allowed for SilcHashTableList. Affected files are
162 lib/silcutil/silchashtable.[ch].
164 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
166 * Defined DLLAPI into silcincludes.h and silcwin32.h for
167 Win32 DLL. extern's in header files are now declared with
170 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Fixed private message handling. It used some old code that
173 caused the client to crash. Affecte file is
174 lib/silcclient/client_prvmsg.c.
176 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
178 * Added function silc_client_add_channel,
179 silc_client_replace_channel_id, and removed functions
180 silc_client_new_channel_id and silc_idlist_get_channel_by_id
183 * Added cross reference of the joined channels to the
184 SilcClientEntry, and changed the SilcChannelEntry's
185 users list to SilcHashTable. The affected files are
186 lib/silcclient/idlist.[ch].
188 * Fixed a bug in hash table tarversing. While the hash table
189 is traversed with SilcHashTableList the table must not be
190 rehashed. It is now guaranteed that auto rehashable tables
191 are not rehashed while tarversing the list. Also defined that
192 silc_hash_table_rehash must not be called while tarversing
193 the table. Added function silc_hash_table_list_reset that must
194 be called after the tarversing is over. The affected files are
195 lib/silcutil/silchashtable.[ch].
197 * Changed all hash table traversing to call the new
198 silc_hash_table_list_reset in server and in client library.
200 * Added function silc_client_on_channel to return the
201 SilcChannelUser entry if the specified client entry is joined
202 on the specified channel. This is exported to application as
203 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
205 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Fixed founder regaining problem with JOIN command on normal
208 server. The notify for mode change must be sent always and
209 not only if !cmd->pending. Affected file silcd/command.c.
211 * Fixed the WHOWAS command's reply sending to support the
212 lists correctly. Affected file silcd/command.c.
214 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
216 * When sending JOIN command to router for processing the
217 sender's old command identifier was not saved back to the
218 sender's command context, fixed now. The affected file is
221 * Create the key in JOIN command of the router did not return
222 the channel key, added check for this. Affected file is
225 * Fixed a channel ID update bug in JOIN command reply. Do
226 not directly upgrade the ID but call the function
227 silc_idlist_replace_channel_id if the ID was changed.
228 Affected file silcd/command_reply.c.
230 * Fixed memory leaks from command calling if it would fail.
231 Affected file silcd/command.c.
233 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
235 * Applied patches from cras:
237 Memory leak fixes around libaries, irssi window resize fix,
238 new silclist.h and silcdlist.h, all extern inline changed to
241 * Removed dotconf from lib/dotconf, not needed anymore.
243 * Removed TRQ from lib/trq, not needed anymore.
245 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
246 with server connections. Later this will be configurable
247 in config file after new config file is done. Affected file
250 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
252 * Fixed a crash in server related to channel announcements.
253 Affected file silcd/server.c.
255 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Fixed memory leaks in silc_server_create_new_channel*
258 functions. Affected file silcd/server.c.
260 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
261 which ID was changed. This way the router will send the
262 user list for the channel again, and server won't be in
263 desync in some rare circumstances. Affected file is
264 silcd/packet_receive.c.
266 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
268 * Check for NULL socket pointer in the function
269 silc_server_packet_send_to_channel_real. Affected file

275 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
277 * Fixed some header addition to Toolkit distribution in
278 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
280 * Added lib/silcclient/client_ops_example.h as an template
281 file for application programmers to quickly start using
282 the SilcClientOperation functions in their application.
283 Updated the lib/silcclient/README as well to tell about this
284 nice file made available.
286 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
288 * Call silc_server_remove_from_channels when removing client
289 entry when NO_SUCH_CLIENT_ID was received. Affected file
290 is silcd/command_reply.c.
292 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
294 * Added server & router operator statistics updating. Affected
295 file silcd/packet_receive.c and silcd/command.c.
297 * Fixed the SERVER_SIGNOFF notify handling on normal server
298 not to save the history information for clients. Same was
299 fixed earlier in remove_clients_by_server function, but not
300 here. Affected file silcd/packet_receive.c.
302 * Raised the default connection-retry count from 4 to 7 in
303 server. Affected file silcd/server.h.
305 * Cancel any possible reconnect timeouts when we start the
306 key exchange. Affected file silcd/server.c.
308 * Do not reconnect on connection failure when SCONNECT was
309 given. Affected files silcd/server.[ch].
311 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
313 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
315 * Fixed the NICK command to always give the unformatted
316 nickname to the one giving the NICK command. If unformatted
317 nickname is cached already it will be formatted and the
318 local entry will always get the unformatted nickname.
319 Affected file lib/silcclient/idlist.c.
321 * Fixed some double frees from client library commands.
322 Affected file is lib/silcclient/command.c.
324 * Fixed CUMODE command in server to assure that no one can
325 change founder's mode than the founder itself, there was a
326 little bug. Affected file silcd/command.c.
328 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Removed the SilcClientCommandDestructor from the client
331 libary, it is not needed anymore. Affected files are
332 lib/silcclient/silcapi.h, command[_reply].[ch],
333 client_notify, idlist.c.
335 * Fixed GETKEY command to first resolve client, and then
336 resolve the server only if the client was not found, instead
337 of resolving both at the same time. Affected file is
338 lib/silcclient/command.c.
340 * Added silc_client_start_key_exchange_cb and lookup the
341 remote hostname and IP address before starting the key
342 exchange with server. The affected file is
343 lib/silcclient/client.c.
345 * The server's public key is now saved using the IP address
346 of the server and not the servername for the filename.
347 The hostname public key filename is checked as an fall back
348 method if the IP address based filename is not found.
350 Fixed the GETKEY command to save the fetched server key
353 Print the remote server's hostname now when new key is
354 received during connection process. Affected file is
355 irssi/src/silc/core/client_ops.c.
357 * Return always our own public key to the client if it asks
358 for it with GETKEY command. Affected file silcd/command.c.
360 * Removed the use_auto_addr variable from default config
361 file since it was in wrong section. Affected file is
364 * Fixed TOPIC_CHANGE notification to not route it when it
365 was sent using silc_server_send_notify_to_channel function.
366 Affected file silcd/command.c.
368 * Fixed silc_server_send_notify_kicked to send the kicker's
369 Client ID also, it was missing. Affected files are
370 silcd/command.c, silcd/packet_send.[ch].
372 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Do not save client history information in SERVER_SIGNOFF.
375 Fixes the bug in normal server that it does not detect
376 the client becoming valid after the server becomes back
377 online. Affected file silcd/server_util.c.
379 * Added `sock_error' field into the SilcSocketConnection
380 context. When error occurs during socket operation (read
381 or write) the error is saved. Added also new function
382 silc_socket_get_error to return human readable socket error
383 message. Affected files are lib/silcutil/silcsockconn.[ch],
384 lib/silcutil/unix/silcunixsockconn.c, and
385 lib/silcutil/win32/silcwin32sockconn.c.
387 * The server now prints the socket error message in the
388 signoff for client. Affected file silcd/server.c.
390 * Fixed the `created' channel information sending from router
391 to server in JOIN command. Checks now whether the channel
392 really was created or not and set it according that.
394 Fixed the JOIN command to use the client entry's current
395 ID during the joining procedure instead of the one it sent
396 in the command (it is checked though), since it can change
397 between the packet processing and command processing, and
398 would just case unnecessary pain in the client end. Affected
399 file silcd/command.c.
401 * Fixed a channel key payload sending to use correct channel
402 ID when the server was forced to change the channel's ID by
403 router. Router sent the key payload with the old Channel ID.
404 Affected file silcd/packet_receive.c.
406 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Call silc_server_save_channel_key only if the key payload
409 was provided in the JOIN command's command reply. Affected
410 file silcd/command_reply.c.
412 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Fixed silc_mp_sizeinbase to return the value correctly with
415 MPI. Affected file lib/silcmath/mp_mpi.c.
417 * Fixed the stop_server signal to correctly stop the scheduler
418 and gracefully stop the server when SIGTERM or SIGINT signals
419 are received. Affected file silcd/silcd.c.
421 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
423 * Simple handling of TERM and HUP signals. Also added some log
424 flushing call around. Affected file is
427 * Fixed small bugs in silclog.c. Now buffering output will take
428 effect after 10 seconds since startup: This will ensure that
429 no important startup messages are lost. Also output redirection
430 will preserve original format ([Date] [Type] message).
431 Affected file is lib/silcutil/silclog.c.
433 * Added two options to the config file, in the logging section:
434 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
435 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
437 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Do not print the warning about log files not being initialized
440 more than once to avoid excess logging. Affected file is
441 lib/silcutil/silclog.c.
443 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
444 the SIM copying in make install in Makefile.am.pre.
446 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
448 * Rewritten silclog APIs. Globally interesting changes follows:
449 silc_log_set_files() changed to silc_log_set_file().
450 silc_log_set_callbacks() changed to silc_log_set_callback().
451 ROBOdoc documented silclog header file.
452 SilcLogCb now returns bool to wether inihibit the default
453 handler or not (to keep the old behaviour return always TRUE).
454 The new APIs should also fix the problem of the
455 silcd_error.log file that was written in the current directory.
458 Log files streams will remain opened after silc_log_set_file()
459 call, means less CPU usage notably on high traffic servers.
460 File streams are now full buffered, and flushed to the disk
461 every 5 minutes, lesses HD activity and CPU usage.
462 Messages can be redirected, allowing admins to configure
463 one single logfile for all server messages.
464 the silc_log_quick global variable to activate fast-logging.
465 Affected files lib/silcutil/silclog.[ch]
467 * Changed some code to conform new silclog APIs. Affected
468 files are doc/example_silcd.conf.in, silcd/server.c
469 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
472 * Fixed a memory leak that could occur in some situations.
473 Affected file silcd/serverconfig.c.
475 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Added the silc_client_del_client to remove the client from
478 all channels as well. Affected file lib/silcclient/idlist.c.
480 * Fixed the client library to correctly remove the client
481 from all channels when the client entry is being destroyed.
482 Affected file lib/silcclient/client_notify.c, command.c.
484 * Added auto-nicking support to the client library. If the
485 applicatio now sets client->nickname it will be sent to the
486 server after connecting by the library. This way for example
487 SILCNICK (or IRCNICK) environment variables will have effect
488 and always change the nickname automatically to whatever
489 it is wanted. Affected file lib/silcclient/client.[ch].
491 * Renamed silc_server_command_bad_chars to the
492 silc_server_name_bad_chars and moved it to the
493 silcd/server_util.[ch]. Added also new function
494 silc_server_name_modify_bad to return nickname that
495 includes bad characters as new nickname without those
496 bad characters. This check and modify is now used in
497 silc_server_new_client when the username is initially set
498 as nickname, so it must be checked to be valid nickname.
499 Affected file silcd/packet_receive.c.
501 * The nickname length is now taken from the packet for real
502 and not trusted to strlen() since it clearly can return
503 wrong length for nickname including bad characters. This
504 also applies to channel names. Affected file silcd/command.c.
506 * Removed the lib/silcsilm/modules directory. Modules are now
507 compiled into the lib/silcsim. Fixed the copying of the
508 modules to follow symbolic links in Makefile.am.pre.
510 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
512 * Fixed silc_string_regexify list creation. Fixes bugs with
513 BAN and INVITE commands in server. The affected file is
514 lib/silcutil/unix/silcunixutil.c.
516 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
518 * Removed the command destructor entirely from the server's
519 command and command reply routines. It is not needed, and
520 its usage was buggy and caused crashes. Affected files are
521 silcd/command[_reply].[ch].
523 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Cancel protocol and NULL sock->protocol if timeout
526 occurred during protocol. Affected file silcd/server.c.
528 * Cancel protocol timeouts always before calling the final
529 callback, to assure that after final callback is called
530 no other state will be called for the protocol anymore.
531 Affected file silcd/protocol.c.
533 * Print error log if incoming connection configuration could
534 not be found. Affected file silcd/server.c.
536 * Fixed JOIN command to correctly save the founder mode
537 to the client on normal SILC server, when the channel
538 was created by the router. Affected file silcd/command.c.
540 * Fixed LIST command (hopefully) to send correct reply
541 packets. Affected file silcd/command.c.
543 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
545 * The silc_packet_receive_process now returns FALSE if the
546 read data was invalid packet, and TRUE if it was ok.
548 The server now checks that if unauthenticated connection
549 sends data and its processing fails the server will close
550 the connection since it could be a malicious flooder.
552 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
554 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Make sure the warning about error opening a log file is
557 printed only once and not everytime it fails (produces
558 too much useless log). Affected file lib/silcutil/silclog.c.
560 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
562 * Made the silc_server_daemonise() function more readable.
563 Affected file silcd/server.c.
565 * Pid file is now optional, the user may comment it out from
566 the config file. Removed define SILC_SERVER_PID_FILE, we
567 don't need a default any longer. Affected file
568 configure.in.pre, lib/Makefile.am.pre.
570 * Make some use of the pid file. The server now dies at startup
571 if it detects a valid pid file on his path. The server would
572 die anyway in this circumstance, because of the bind() failure.
573 Affected file silcd/silcd.c.
575 * No longer compiling lib/dotconf.
577 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Fixed JOIN command parsing not to crash. Affected file
580 lib/silcclient/command.c.
582 * Fied the NICK_CHANGE notify to add the new client entry
583 even it is resolved. This removes an <[unknown]> nick
584 thingy bug in the client. Affected file is
585 lib/silcclient/client_notify.c.
587 * Do not try to allocate 0 bytes (efence does not like it)
588 in lib/silccore/silccomand.c when encoding payload.
590 * Do not take IRCNICK as nickname in Irssi SILC client since
591 it is not possible to set nickname before hand connecting
592 the server (TODO has an entry about adding auto-nicking
595 * Changed the silc_server_command_pending to check whether
596 there already exists an pending entry with the specified
597 command, command identifier and pending callback. This is
598 to fix IDENTIFY and WHOIS related crashes that may register
599 multiple pending commands with same identifier. Affected
600 file silcd/command.c.
602 * Fixed the server to reconnect to the router even if it
603 was already reconnecting and EOF was received. This to
604 fix a possibility that the server wouldn't ever try to
605 auto-reconnect to the router. Affected file silcd/server.c.
607 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Fixed the server's password authentication to use the
610 length of the locally saved password, and not the one
611 sent in the packet. Affected file silcd/protocol.c.
613 * Fixed same password authentication problem in the
614 Authentication Payload handling routines in
615 lib/silccore/silcauth.c.
617 * Yet another password authentication problem fixed with
618 channel password handling in silcd/command.c.
620 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
622 * If first character of string in silc_parse_userfqdn is '@'
623 then do not parse it. Affected file is
624 lib/silcutil/silcutil.c.
626 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
628 * Fixed minor bug in IDENTIFY command reply sending, which
629 caused various weird problems during JOIN when it was
630 resolving names for users. Affected file silcd/command.c.
632 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Fixed the IDENTIFY command reply sending to chech better valid
635 clients. It was possible to send incomplete list of replies.
636 Affected file silcd/command.c.
638 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Added silc_client_command[s]_[un]register functions now to
641 dynamically register the commands in client library. Removed
642 the static table of commands. This allows the client library
643 to call commands without causing the application to know about
644 what commands library has called.
646 Removed the INFO command reply kludge to detect when the command
647 was called by library. Now library use its own command reply
648 function for INFO command.
650 Added function silc_client_command_call to call a command.
651 Application can use it to call command, not access the structure
654 Now all commands that are sent by the client library (not
655 explicitly sent by application) use own command reply functions.
657 Affected files around lib/silcclient/ and in
658 irssi/src/silc/core/.
660 * Fixed the WHOIS command reply sending to chech better valid
661 clients. It was possible to send incomplete list of replies.
663 Fixed the WHOIS and IDENTIFY to send the request to router
664 if normal server did not do it and did not find any results.
666 Affected file silcd/command.c.
668 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Moved the internal data from SilcClient context into its
671 own file, not accesible to application. Affected files
672 lib/silcclient/client.h and lib/silcclient/client_internal.h,
673 and other files in client library.
675 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Added doc/examples installation target in Makefile.am.pre.
680 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
682 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
683 commands the found client entry will be removed from the
684 cache, after notifying application about the error. Affected
685 file lib/silcclient/command_reply.c.
687 * Changed the /MSG to check for exact nickname user gave, and
688 not let `nick' match `nick@host' if it is only one found. Now,
689 user must type the exact nickname (like nick@host2) even if
690 there are no more than one same nicks found. This is to avoid
691 a possibility of sending nickname to wrong nickname since
692 `nick' could match `nick@host'. Affected file is
693 irssi/src/core/silc-servers.c.
695 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Do not print "you are now server operator" or similar when
698 giving /away command. Affected files are
699 irssi/src/silc/core/client_ops.c, silc-servers.h.
701 * Made the silc_server_command_pending_error_check to send
702 the same command reply payload it received back to the
703 original sender of the command. This way all arguments
704 that was received by the server will be received by the
705 client too. Affected file silcd/command.c.
707 * Added the silc_idcache_add to return the created cache entry
708 to a pointer. Affected file lib/silccore/silcidcache.[ch].
710 * Add global clients to expire if they are not on any channel.
711 This is because normal server will never know if they signoff
712 if they are not on any channel. The cache expiry will take
713 case of these entries. This is done by normal servers only.
714 The affected files are silcd/command_reply.c,
715 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
717 * If server receives invalid ID notification for WHOIS or
718 IDENTIFY and the ID exists in the lists, it is removed.
719 Affected file silcd/command_reply.c.
721 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
722 in client then client entry that it matches is searched and
723 the nickname is printed on the screen for user. Affected
724 file irssi/src/silc/core/client_ops.c.
726 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
728 * Use cache entry expire time in the LIST command reply to
729 purge old entries from the cache after the LIST command
730 reply has been received. This way we don't have non-existent
731 entries in the cache for too long. Affected file is
732 silcd/command_reply.c.
734 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
736 * If we are normal server, and we've not resolved client info
737 in WHOIS or IDENTIFY from router, and it is global client,
738 we'll check whether it is on some channel. If it is not
739 then we cannot be sure about its validity and will resolve it
740 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
741 file silcd/command.c.
743 * Search channel by name (if possible) rather than by ID
744 in IDENTIFY command's command reply. Affected file is
745 silcd/command_reply.c.
747 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Distribute to the channel passphrase in CMODE_CHANGE notify.
750 Updated specs and implemented it. Affected file silcd/command.c,
751 silcd/packet_send.c and silcd/packet_receive.c.
753 * Implemented the <founder auth> payload handling in the JOIN
754 command. If provided all conditions for channel joining
755 except requirement to provide correct passphrase can be
756 overrided by the channel founder. Updated the protocol specs.
757 Affected file silcd/command.c.
759 Added support for founder auth in JOIN command in client
760 library. Fixed the parsing of the JOIN command now to support
761 all options as they should be. The affected file is
762 lib/silcclient/command.c.
764 * Optimized the WHOIS and IDENTIFY commands to send the request
765 to router only if it includes nicknames or other names. If
766 they include only IDs then check the local cache first before
767 routing. Affected file is silcd/command.c.
769 * Added channels topic announcements. Affected file is
770 silcd/packet_receive.c and silcd/server.c.
772 * Fixed the silc_server_send_notify_topic_set to really destine
773 the packet to channel. Affected file silcd/packet_send.c.
775 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
776 library. Affected file lib/silcclient/client_notify.c.
778 * Added UMODE announcements. Affected file silcd/server.c.
780 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Memory leak fixes in:
784 lib/silcutil/silcsockconn.c
785 lib/silcske/silcske.c
788 lib/silccrypt/silcpkcs.c
789 lib/silccore/silccommand.c
790 lib/silccore/silcidcache.c
795 * ROBOdoc documented the lib/silcske/groups.h file and a
796 bit changed the interface for better.
798 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
800 * Update the client entry context in the ID cache after
801 nick change. Affected file lib/silcclient/command.c.
802 Fixes the CUMODE command when regaining founder privileges,
803 and a little WHOIS problem.
805 * Fixed silc_net_gethostbyname to correctly call the
806 inet_ntop. Affected file lib/silcutil/silcnet.c.
808 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
810 * Added IPv6 support checking to the configure.in.pre, added
811 also --enable-ipv6 option to override the check. Affected
812 file configure.in.pre.
814 * The silc_thread_create now calls the start function
815 directly if threads support is not compiled in. Removes
816 ugly #ifdef's from generic code. Affected files are
817 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
819 * Added silc_net_gethostby[name/addr]_async to asynchronously
820 resolve. Affected files are lib/silcutil/silcnet.[ch].
822 * Added support for rendering IPv6 based server, client and
823 channel IDs. Affected file lib/silcutil/silcutil.c.
825 * Added support for creating IPv6 based server IDs. Affected
826 file is silcd/serverid.c.
828 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
830 * Added silc_net_gethostby[addr/name] into the
831 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
832 routines. Added silc_net_is_ip[4/6]. Affected file is
833 lib/silcutil/unix/silcunixnet.c. All routines that take
834 address as argument now supports both IPv4 and IPv6 addresses.
836 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
838 * Fixed LIST command reply sending in server. Affected file
841 * Server now sends the kicker's client ID in the KICK notify
842 to the kicked client. Affected file silcd/command.c.
844 * The client library now parses the kickers client ID and
845 UI displays it. Affected files lib/silcclient/client_notify.c
846 and irssi/src/silc/core/silc-channels.c, module-formats.c.
848 * Made all payload parsing function prototypes consistent.
849 They all take now const unsigned char * and uint32 pair as
850 the payload data instead of SilcBuffer. Changes all around
851 the source tree. Other unsigned char* -> const unsigned char*
852 changes around the tree as well.
854 * Optimized SFTP client and server packet sending not to
855 allocate new buffer for each packet but to recycle the
856 first allocated buffer. Affected files are
857 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
859 * Optimized the SFTP client to use SilcList instead of
860 SilcDList for requests, because it is faster. Affected file
861 is lib/silcsftp/sftp_client.c.
863 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
864 into lib/silccore/silcid.[ch].
866 Renamed silcpayload.[ch] into silcargument.[ch].
868 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * If client entry is deleted with active key agreement
871 session, abort the session.
873 The silc_client_abort_key_agreement now calls the completion
874 callback with new SILC_KEY_AGREEMENT_ABORTED status.
876 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
879 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Don't use __restrict in older GCC's. Affected file is
882 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
884 * silc_net_localhost now attempts to reverse lookup the
885 IP/hostname. Affected file lib/silcutil/silcnet.c.
887 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
888 command. It can be used to gain founder privileges at
889 the same time when joining the channel.
891 Defined that the SILC_NOTIFY_TYPE_KICKED send the
892 kicker's client ID as well. Updated protocol specs.
894 Defined that the server must send SILC_COMMAND_IDENTIFY
895 command reply with error status to client who sent
896 private message with invalid client ID.
898 Updated the protocol specification.
900 * Added silc_server_send_command_reply to send any
901 command reply. Affected file silcd/packet_send.[ch].
903 * Added silc_id_payload_encode_data to encode ID payload
904 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
906 * The server now send IDENTIFY command reply with error
907 status if client ID in private message is invalid. Affected
908 file silcd/packet_receive.c.
910 * Save the server key file with server's IP address in
911 the filename instead of hostname. The affected file is
912 irssi/src/silc/core/client_ops.c.
914 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
919 * Added libtool support for compiling shared objects in
920 lib/silcsim. Affected file configure.in.pre and
921 lib/silcsim/Makefile.am. Original patch by cras.
923 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Pid file configuration, and server's config file fixes
926 patch by toma. Updated CREDITS file.
928 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed silc_client_channel_message to not try to decrypt
931 the message twice if it resolved the destination client
932 information. This could cause of dropping one channel
933 message. Affected file lib/silcclient/client_channel.c.
935 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Added silc_client_run_one into lib/silcclient/silcapi.h and
938 lib/silcclient/client.c. This function is used when the SILC
939 Client is run under some other scheduler, or event loop or
940 main loop. On GUI applications, for example this may be
941 desired to used to run the client under the GUI application's
942 main loop. Typically the GUI application would register an
943 idle task that calls this function multiple times in a second
944 to quickly process the SILC specific data.
946 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
948 * Fixed silc_server_drop() for dropping the supplementary
949 groups as well, this could cause a security hole on some
952 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
954 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
957 * Write PID file after dropping privileges. Added -F option
958 to run server on foreground. A patch by debolaz.
959 Affected files silcd/server.c, silcd/silcd.c.
961 * Fixed MOTD to return the MOTD file server name. Affected
962 file silcd/command.c.
964 * Added INFO command reply handling to the Irssi SILC Client.
965 Affected file irssi/src/silc/core/client_ops.c.
967 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
969 * Fixed the silc_idcache_list_* routines to really support
970 the dynamic list. Fixes a crash. Affected file is
971 lib/silccore/silcidcache.c.
973 * Fixed the LIST command reply to really call LIST command's
974 pending callbacks. Affected file silcd/command_reply.c.
976 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Update conn->local_entry->nickname after giving NICK
979 command. Affected file lib/silcclient/command.c.
981 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
983 * Added the [pid] option to the silcd configuration file
985 Affected files: serverconfig.[ch] and silcd.c
987 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Save fingerprint in WHOIS command reply in server.
990 Affected file silcd/command_reply.c.
992 * Fixed NICK commands pending callback registration.
993 Affected file lib/silcclient/command.c.
995 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
997 * Use ++server->cmd_ident when sending commands in server,
998 instead of random number. Affected file silcd/command.c.
1000 * Fixed GETKEY command reply to call actually GETKEY pending
1001 command callbacks. Affected file silcd/command_reply.c.
1003 * A bit stricter check for nicknames. Check for same nickname
1004 in NICK command also. Affected file silcd/command.c.
1006 * Do not call INFO command everytime client ID changes, only
1007 during first connecting. Affected file lib/silcclient/client.c.
1009 * Set the new nickname only after successful command reply for
1010 NICK command is returned by server. Affected file
1011 lib/silcclient/command.c.
1013 * Remove nicknames from nicklist during server_signoff notify.
1014 Should fix /NAMES bit more. The affected file is
1015 irssi/src/silc/core/silc-channels.c.
1017 * Added `fingerprint' field to the SilcIDListData in the
1018 silcd/idlist.h to hold the fingerprint of the client's
1021 Send the fingerprint of the client's public key in WHOIS
1024 Affected files silcd/command.c, and silcd/idlist.[ch].
1026 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1027 create fingerprint from given data.
1029 * Show the fingerprint of the client's public key in WHOIS.
1030 Affected files irssi/src/module-formats.[ch] and
1031 irssi/src/silc/core/client_ops.c.
1033 * Format the multiple same nicknames also during JOIN and
1034 NICK_CHANGE notifys. Affected file is
1035 lib/silcclient/client_notify.c.
1037 * Do not print error on screen for invalid private message
1038 payload since it can come if someone is sending private
1039 messages with wrong key. Affected file
1040 lib/silccore/silcprivate.c.
1042 * Fixed multiple concurrent /PING crash. Affected file
1043 lib/silcclient/command.c.
1045 * Changed the wrong ID encoding. All IP addresses must be
1046 in MSB first order in encoded format. They were encoded
1047 wrong and was in LSB format. Affected files are
1048 silcd/serverid.c, lib/silcutil/silcutil.c.
1050 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1052 * Call the `connect' client operation through the scheduler
1053 in case of error. Affected file lib/silcclient/client.c.
1055 * Call the `failure' client operation even if the error
1056 occurred locally during a protocol. Affected file is
1057 lib/silcclient/protocol.c.
1059 * Added support of sending LIST command to router from normal
1060 server. This way normal server can get list of all channels
1061 in the network too. Fixed the channel list sending in the
1062 server too. Affected files are silcd/command.c, and
1063 silcd/command_reply.[ch].
1065 * Added silc_server_update_channels_by_server and
1066 silc_server_remove_channels_by_server. They are used during
1067 disconnection of primary router and in backup router protocol.
1068 Affected file silcd/server_util.[ch], silcd/server.c and
1069 silcd/server_backup.c.
1071 * Fixed channel adding to global list in IDENTIFY command
1072 reply in server. Affected file silcd/command_reply.c.
1074 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * If the incoming packet type is REKEY or REKEY_DONE process
1077 that packet always synchronously. Fixes yet another MAC
1078 failed error on slow (dialup) connections. Affected file
1079 lib/silcclient/client.c and silcd/server.c.
1081 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Call check_version SKE callback for initiator too. Affected
1084 file lib/silcske/silcske.c.
1086 * Implemented fix for security hole found in the SKE that was
1087 fixed in the specification few days back; the initiator's
1088 public key is now added to the HASH value computation.
1089 Added backwards support for the old way of doing it too, for
1090 old clients and old servers. Affected file is
1091 lib/silcske/silcske.c.
1093 * Enabled mutual authentication by default in SKE. If initiator
1094 is not providing mutual authentication the responder will
1095 force it. This will provide the proof of posession of the
1096 private key for responder. The affected files are
1097 lib/silcclient/protocol.c and silcd/protocol.c.
1099 * Do not cache anymore the server's public key during SKE.
1100 We do mutual authentication so the proof of posession of
1101 private key is done, and if the server is authenticated in
1102 conn auth protocol with public key we must have the public
1103 key already. Affected file silcd/protocol.c.
1105 * Added new global debug variable: silc_debug_hexdump. If
1106 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1107 file lib/silcutil/silclog.[ch].
1109 * Fixed compilation warning due to char * -> const char *.
1110 Affected files lib/silcutil/silcnet.h, and
1111 lib/silccore/silcauth.[ch].
1113 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Fixed CMODE command when new channel key was created. If
1116 the creation failed the old key was removed. Next time giving
1117 same command would crash the server since the old key was
1118 freed already. Affected file silcd/command.c.
1120 * Fixed the silc_server_announce_get_channels to not crash
1121 on reconnect. Affected file silcd/server.c.
1123 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Added silc_log_set_debug_string function to set a regex
1126 string to match for debug output. Only the function names,
1127 or filenames matching the given debug string is actually
1128 printed. This way it is possible to filter out those debug
1129 strings that user is not interested in.
1131 Fixed a bug in silc_string_regexify.
1133 Affected files lib/silcutil/silclog.[ch], and
1134 lib/silcutil/unix/silcunixutil.c.
1136 * Changed the -d options in both server and Irssi SILC client
1137 to take the debug string as argument. Affected files
1138 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1140 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Added silc_hash_babbleprint to create a Bubble Babble
1143 Encoded fingerprint. The encoding is developed by Antti
1144 Huima (draft-huima-babble-01.txt), and it creates human
1145 readable strings out of binary data. Affected file
1146 lib/silccrypt/silchash.[ch].
1148 * Print the babble print now in addition of fingerprint as well
1149 in Irssi SILC client. Affected files are
1150 irssi/src/fe-common/silc/module-formats.[ch],
1151 irssi/src/fe-common/silc/core/client_ops.c.
1153 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed a security problem found in SKE. The initiator's
1156 public key too is now added to the HASH hash value creation
1157 which is signed by the responder to create the SIGN value.
1158 This will prevent anyone in the middle to lie to the responder
1159 about the initiator's public key. If this is done now, the
1160 man in the middle will get caught. Updated the protocol
1163 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Better installation directory handling. Configure module
1166 paths and other paths automatically to example_silc* files
1167 in doc/. A patch by toma.
1169 * Fixed compiler warning from MPI library, and from SILC RNG.
1172 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1173 It can be configured with ./configure. A patch by toma.
1175 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Find correct make to use in prepare-clean. A patch by
1178 toma. Affected file prepare-clean.
1180 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1182 * Added irssi variables use_auto_addr, auto_bind_ip,
1183 auto_bind_port and auto_public_ip.
1185 * Changed the interface for silc_client_send_key_agreement
1186 in lib/silcclient/silcapi.h
1190 irssi/src/silc/core/silc-core.c
1192 lib/silcclient/silcapi.h
1193 irssi/src/silc/core/silc-channels.c
1194 lib/silcclient/client_keyagr.c
1197 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Added silc_pkcs_public_key_compare to compare two
1200 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1202 * Check that the client who set the founder mode on the
1203 channel is the same client that is giving the founder
1204 mode to itself. It is done by comparing the saved public
1205 key (it is saved even in the authentication is passphrase).
1206 Affected file silcd/command.c.
1208 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Do not process packet for disconnected socket connection.
1211 Affected file lib/silccore/silcpacket.c.
1213 * Process the DISCONNECT packet through scheduler in the
1214 client library. Affected file lib/silcclient/client.c.
1216 * Fixed the silc_client_packet_parse to not to increase
1217 the packet sequence number if the conn->sock and the
1218 current socket connection is not same. This can happen
1219 for example during key agreement when the conn includes
1220 multiple socket connections (listeners). Affected file
1221 lib/silcclient/client.c.
1223 * The sender of the file transfer request now provides also
1224 the pointer (listener) for the key exchange protocol. If
1225 the listener cannot be created then it sends empty key
1226 agreement and lets the receiver provide the listener.
1228 Added `local_ip' and `local_port' arguments to the
1229 silc_client_file_send. If they are provided they are used,
1230 if not then it will attempt to find local IP address, if
1231 not found or bind fails then the remote client will provide
1234 Affected files are lib/silcclient/client_ftp.c and
1235 lib/silcclient/silcapi.h.
1237 * Extended the FILE SEND command to support defining the
1238 local IP and port for key exchange listener. They are
1239 optional. Affected file irssi/src/silc/core/silc-servers.c.
1241 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Defined to WHOIS command reply the sending of fingerprint
1244 of the client's public key (if the proof of posession of the
1245 corresponding private key is verified by the server).
1246 Updated to the protocol specification.
1248 * Added support of receiving the client's public key's
1249 fingerprint in command reply in client library. Affected
1250 file is lib/silcclient/command_reply.c, and
1251 lib/silcclient/idlist.[ch].
1253 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * Do not send over 128 chars long nickname to the server
1256 in NICK command. Affected file lib/silcclient/command.c.
1258 * Do not send over 256 chars long channel names to the server
1259 in JOIN command. Affected file lib/silcclient/command.c.
1261 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Assure that silc_server_close_connection cannot be called
1264 twice for same socket context. Affected file is
1267 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Send error message to application if opening file for
1270 writing during file transfer fails. Affected file is
1271 lib/silcclient/client_ftp.c.
1273 Remove all file transfer sessions for a client that we're
1274 removing from ID cache.
1276 Affected file is lib/silcclient/client_ftp.c.
1278 * Fixed silc_net_addr2bin to return correct address. Affected
1279 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1281 * Fixed file transfer session removing on signoff notify.
1282 Affected file irssi/src/silc/core/silc-servers.c.
1284 * Added the SilcClientFileError to be returned in the monitor
1285 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1286 Affected file lib/silcclient/silcapi.h.
1288 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Fixed a crash in silc_client_ftp_free_sessions and
1291 silc_client_ftp_session_free_client. Affected file
1292 lib/silcclient/client_ftp.c.
1294 * Added `disabled' field in the SilcChannelEntry in the server
1295 to indicate if the server entry is disabled. Affected file

1305 * Fixed a crash in client resolving in client_prvmsg.c in
1306 client library. Affected file lib/silcclient/client_prvmsg.c.
1308 * Do not actually remove the client directly from ID cache
1309 during SERVER_SIGNOFF, but invalidate it. This way we
1310 preserve the WHOWAS info for the client. Affected file
1311 silcd/server_util.c.
1313 * Fixed SERVER_SIGNOFF notify handling in the server. The
1314 server is now able to process incoming SERVER_SIGNOFF notify
1315 for a server that it doesn't even know about. It will remove
1316 the clients provided in the notify. Affected file
1317 silcd/packet_receive.c.
1319 * Check for partial packet in data queue after every packet that
1320 was found from the queue. Return and wait for more data if
1321 there is partial data in queue. Affected file is
1322 lib/silccore/silcpacket.c.
1324 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added SilcClietFileError enum to indicate error in
1327 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1328 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1329 Affected files lib/silcclient/silcapi.h and
1330 lib/silcclient/client_ftp.c.
1332 * Check that newsize in silc_buffer_realloc is larger than
1333 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1335 * Added better monitor of file transfers. It now monitors
1336 key agreement protocol during the file transfer too. Added
1337 error reporting too. Affected files
1338 irssi/src/silc/core/silc-servers.c,
1339 irssi/src/fe-common/silc/module-formats.[ch].
1341 * Wrote a help file for FILE command.
1343 * Added silc_rng_global_get_byte_fast to get not-so-secure
1344 random data as fast as possible. Random data is read from
1345 /dev/urandom if available and from the SILC RNG if not
1346 available. It is used in padding generation. Affected file
1347 lib/silccrypt/silcrng.[ch].
1349 * All packets in client library are now processed synchronously.
1350 Optimized packet processing a lot. Affected file
1351 lib/silcclient/client.c.
1353 * All server connection packets are processing synchronously
1354 now in server, to optimize packet processing. Affected file
1357 * Include files are installed now only in Toolkit distribution
1358 if make install is given. Affected files: all Makefile.am's.
1360 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Assure that silc_client_notify_by_server_resolve does not
1363 resolve the client information multiple times. If it cannot
1364 be found by the first it cannot be found at all. Affected
1365 file lib/silcclient/client_notify.c.
1367 * Fixed WHOWAS command reply calling. Affected file
1368 lib/silcclient/command_reply.c.
1370 * Removed all references to silc_idlist_get_client from the
1371 Irssi SILC client since that call is internal call used by
1372 the library. The Irssi SILC client will use now client
1373 retrieval functions found in silcapi.h.
1375 * Fixed a bug in resolving nickname info before sending
1376 private message. It used freed memory. Affected file
1377 irssi/src/silc/core/silc-servers.c.
1379 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Assure my_channels statistics cannot go negative in server.
1382 Affected files silcd/server.c, silcd/server_util.c.
1384 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1388 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1398 * Added silc_net_localip to return local host's IP address.
1399 Affected file lib/silcutil/silcnet.[ch].
1401 * If key exchange or rekey protocol is active for a connection
1402 parse all packets syncronously since there might be packets
1403 in packet queue that we are not able to process without first
1404 processing packets before them. Affected file silcd/server,
1405 lib/silcclient/client.c.
1407 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1408 whether library should continue processing the packet.
1409 Affected file lib/silccore/silcpacket.h.
1411 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1412 SilcSFTPMonitorData to SFTP server to monitor various
1413 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1420 Added preliminary support for simple client to client one-file
1421 transmission. Affected file lib/silcclient/client_ftp.c,
1422 lib/silccilent/client.[ch].
1424 * Added new local command FILE to the Irssi SILC Client.
1425 It is used to perform the file transfer. It has subcommands
1426 SEND, RECEIVE, SHOW and CLOSE. Affected files
1427 irssi/src/silc/core/client_ops.c,
1428 irssi/src/silc/core/silc-server.[ch].
1430 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Relay the SILC_PACKET_FTP in the server. Affected files
1433 silcd/server.c and silcd/packet_receive.c.
1435 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Renamed silc_file_read and silc_file_write to functions

1440 lib/silcutil/silcutil.[ch].
1442 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Resolve the client info when received private message or
1445 channel message for a client which nickname we don't know.
1446 Affected files lib/silcclient/client_prvmsg.c and
1447 lib/silcclient/client_channel.c.
1449 * Do not crash in /KEY if client is not connected. Affected
1450 file irssi/src/silc/core/silc-channels.c.
1452 * Added SilcClientStatus field to the SilcClientEntry in the
1453 lib/silcclient/idlist.h.
1455 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1456 is incomplete and is being resolved, it won't be resolved
1459 Make sure also that USERS command reply does not resolve
1460 twice information. Affected file is
1461 lib/silcclient/command_reply.c.
1463 Make sure that silc_client_get_clients_by_list does not
1464 resolve twice same information.
1466 * Check for valid client->id in the silc_server_free_client_data.
1467 Affected file silcd/server.c.
1469 * Fixed /GETKEY nick@server not to crash if the server entry
1470 is not found. Affected file lib/silcclient/command.c.
1472 * Fixed the silc_server_check_cmode_rights to check the
1473 requested modes correctly. Affected file silcd/command.c.
1475 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Better checks for non-printable chars in nick added.
1478 Affected file silcd/command.c.
1480 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Call the silc_server_udpate_servers_by_server in the
1483 primary router that comes back online in the backup resuming
1484 protocol. Otherwise it routes packets wrong. Affected file
1485 silcd/server_util.[ch], silcd/server_backup.c.
1487 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1490 lib/silcutil/silcbuffmt.[ch].
1492 * Redefined the SILC packet header to include the padding
1493 length. Affected file lib/silccore/silcpacket.[ch].
1495 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1496 length for maximum padding up to 128 bytes). Affected
1497 file lib/silccore/silcpacket.h.
1499 * Removed all backwards support for old 0.5.x MAC thingies.
1500 The SILC packet header change makes it impossible to be
1501 backwards compatible.
1503 * Send the ENDING packet with timeout in the backup resuming
1504 protocol. This is to assure that all routers has connected
1505 to the primary router. Affected file silcd/server_backup.c.
1507 * Changed the RNG to take the first IV from random data. It
1508 used to take it from zero actually. Changed the RNG also
1509 to use /dev/urandom during session. /dev/random is used
1510 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1512 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Changed the SILC packet header to have the first two bytes
1515 (the packet length) encrypted. Affected files aroung the
1516 code tree, lib/silccore/silcpacket.[ch]. Removed the
1517 SilcPacketCheckDecrypt callback. It is not needed anymore
1518 since the silc_packet_receive_process will determine now
1519 whether the packet is normal or special.
1521 * Implemented the unidirectional MAC keys. Affected files
1522 lib/silcske/silcske.c, silcd/protocol.c and
1523 lib/silcclient/protocol.c.
1525 * Implemented the packet sequence number to the MAC computation.
1526 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1527 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1528 lib/silcclient/protocol.c.
1530 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Allow backup router to announce servers. All servers
1533 announced by backup router are added to the global list
1534 automatically. Update hte server's socket to our primary
1535 router also when backup router announces a server.
1536 Affected file silcd/packet_receive.c.
1538 * Do not update the client->router in the function
1539 silc_server_udpate_clients_by_server if the client is on
1540 global list. We might fail to find any specific server
1541 for locally connected clients and local cell clients. They
1542 should still use the `from' and not `to' as client->router.
1543 This fixes backup router resuming protocol. Affected file
1544 silcd/server_util.c.
1546 * Decrease channel statistics count only if the channel
1547 deletion worked. Affected files are silcd/server.c and
1548 silcd/server_util.c.
1550 * Added silc_server_update_servers_by_server to update origin
1551 of all server entries. Used during backup router protocol.
1552 Affected files silcd/server_util.[ch], silcd/server.c. and
1553 silcd/backup_router.c.
1555 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1556 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1557 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1558 lib/silccrypt/silchmac.c.
1560 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Assure that router cannot reroute the same channel message
1563 to the sender. Affected file silcd/packet_receive.c.
1565 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Made better checks that the channel message is not sent
1568 to the router it came from. Affected file is
1569 silcd/packet_send.c. Fixed memory leak too.
1571 * Announce informations for incoming router connection, but
1572 only after checking if it is replaced by backup router.
1573 Affected file silcd/packet_receive.c.
1575 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Fixed the backup resuming protocol to work in multiple
1578 router environment. Affected file silcd/server_backup.c.
1580 * Route packet only to one router in the function
1581 silc_server_packet_send_to_channel. Affected file is
1582 silcd/packet_send.c.
1584 * Fixed silc_server_send_notify_dest to set the broadcast
1585 flag. Fixed the silc_server_send_notify_topic to actually
1586 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1587 Affected file silcd/packet_send.c.
1589 * Changed the SFTP Filesystem interface. Changed the
1590 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1591 the filesystem operation function. The SilcSFTPFilesystem
1592 is now a context that is allocated by all filesystem allocation
1593 functions and it already includes the operations structure
1594 and filesystem specific context. It is given as argument
1595 now to the silc_sftp_server_start. This made the interface
1596 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1597 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1599 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Changed the backup router adding and getting interfaces
1602 in the server. The router that will be replaced by the
1603 specified backup router is now sent as argument. Affected
1604 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1607 * Added silc_net_addr2bin_ne to return the binary form of
1608 the IP address in network byte order. Affected files
1609 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1611 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Check for existing server ID in silc_server_new_server
1614 and in silc_server_connect_to_router_final and remove the
1615 old entry if it exists. Affected file silcd/packet_receive.c,
1618 * Send the channel message always to only one router, either
1619 in upstream or downstream. Affected file is
1620 silcd/packet_send.c.
1622 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Wrote the definition of the backup resuming protocol to the
1625 protocol specification.
1627 * Removed one redundant channel key generation from normal
1628 server during joining procedure. Removed one redundant
1629 channel key sending from server to router during joining
1630 procedure. Affected file silcd/command.c.
1632 * Made minor bugfixes to the backup router resuming protocol.
1633 Affected file silcd/server_backup.c, server.c.
1635 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added --disable-asm configuration option. Affected files
1638 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1641 * Implemented the backup resuming protocol that is used to
1642 resume the primary router position in the cell after the
1643 primary router comes back online. Affected files
1644 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1645 and silcd/server_util.[ch].
1647 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Sleep two (2) seconds after sending QUIT command to server.
1650 Affected file lib/silcclient/command.c.
1652 * Assure that if outgoing data buffer is pending do not force
1653 send any data. Affected file silcd/packet_send.c.
1655 * Assure that if outgoing data buffer is pending do not force
1656 send any data. Affected file lib/silcclient/client.c.
1658 * Implemented the backup router support when the primary router
1659 goes down. The servers and routers can now use the backup
1660 router as new primary router without loosing connectivity.
1662 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1665 in the server to indicate disabled entry. All data read
1666 from the connection will be ignored and no data is sent
1667 for entry that is disabled. Affected files are
1668 silcd/idlist.h, silcd/server.c.
1670 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Created SFTP client and server test programs in the
1673 lib/silcsftp/tests directory.
1675 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Implemented memory filesystem (virtual filesystem) for
1678 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1681 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Implemented the SFTP (SSH File Transfer Protocol) to the
1684 lib/silcsftp. It includes SFTP client and SFTP server
1687 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Moved lib/silccore/silcprotocol.[ch] to the
1690 lib/silcutil library.
1692 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1693 take variable argument list pointer as argument. Affected
1694 file lib/silcutil/silcbuffmt.[ch].
1696 * Added silc_buffer_set function that is used to set data
1697 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1698 Affected file lib/silcutil/silcbuffer.h.
1700 * Changed various routines in the core library to use the new
1701 silc_buffer_set instead of allocating new buffer only for
1704 * Added 64-bit value formatting and unformatting support to the
1705 silc_buffer_[un]format routines. Affected file is
1706 lib/silcutil/silcbuffmt.[ch].
1708 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1709 to includes/bitmove.h.
1711 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Fixed channel user mode saving in client library. Affected
1714 file lib/silcclient/command[_reply].c.
1716 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Defined the file transfer to the SILC Protocol. Added
1719 new packet type SILC_PACKET_FTP and defined File Transfer
1720 Payload. The mandatory file transfer protocol is SFTP
1721 (SSH File Transfer Protocol). Affected file in addition
1722 of the internet draft is lib/silccore/silcpacket.h.
1724 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1725 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1726 is used as part of backup router protocol when the primary
1727 router of the cell is back online and wishes to resume
1728 the position as primary router.
1730 * Redefined the MAC generation keys in the protocol. The
1731 same key is not used anymore in both direction. Both
1732 direction will now use different keys for sending and
1733 receiving. This fixes a potential security flaw. This
1734 change causes incompatibilities in the protocol.
1736 * Redefined also the MAC computation from the packet.
1737 An packet sequence number is now added to the MAC
1738 computation. This prevents possible replay attacks against
1739 the protocol. This change too causes incompatibilities
1742 Added `sequence' field to the SilcPacketContext to hold
1743 the current sequence number for the packet.
1745 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Added `created' field to the SilcIDListData in the file
1748 silcd/idlist.h to indicate the time when the entry was
1751 * Added `created' field to the SilcChannelEntry too. Affected
1752 file silcd/idlist.h.
1754 * Added `creation_time' aguments to all the announcement functions
1755 in the server. If it is provided then only the entries that
1756 was created after the provided time frame are actually
1757 announced. Affected file silcd/server.[ch].
1759 * The protocol says that the Channel ID's IP address must be
1760 based on the router's IP address. Added check for this in
1761 the silc_server_new_channel when processing incoming New Channel
1762 Payload. Affected file silcd/packet_receive.c.
1764 * Print out the correct version with --version in SILC client.
1765 Affected file irssi/src/silc/core/silc-core.c.
1767 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Fixed WHOWAS command to check for completnes of the client
1770 entry always, not just when the command is coming from client.
1771 Affected file silcd/command.c.
1773 * Added new function silc_server_packet_queue_purge to purge the
1774 outgoing data queue to the network. After the function returns
1775 it is guaranteed that the outgoing packet queue is empty.
1776 Affected file silcd/packet_send.[ch].
1778 * Purge the outgoing packet queue in the rekey protocol's final
1779 callback to assure that all rekey packets go to the network
1780 before quitting the protocol. Affected file silcd/server.c.
1782 * Added silc_client_packet_queue_parse as similar function as
1783 in server to the client library. The affected file is
1784 lib/silcclient/client.c.
1786 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Splitted silcd/server.c and created silcd/server_util.[ch]
1789 for utility functions.
1791 * Added new socket flag SILC_SF_DISABLED to indicate that the
1792 connection is open but nothing can be sent to or received from
1793 the connection. Affected file lib/silcutil/silsockconn.[ch].
1794 The checking for disabled socket is checked in the low level
1795 silc_socket_write and silc_socket_read functions.
1797 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Allow only nicknames and channel names that fits into the
1800 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1802 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * When processing JOIN command reply in server check that if
1805 the channel exists in our global list we'll move it the local
1806 list. Affected file silcd/command_reply.c.
1808 * Fixed the check whether client is joined on the channel already
1809 in JOIN command. Affected file lib/silcclient/command.c.
1811 * Fixed the JOIN command reply to check whether the channel
1812 already exists. Affected file lib/silcclient/command_reply.c.
1814 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Added silc_ske_status_string to map the SKE error numbers
1817 to readable strings. The affected files are
1818 lib/silcske/silcske[_status].[ch].
1820 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Do not show the private channels on the WHOIS channel list
1823 as it is not allowed by the protocol. The affected file is
1826 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Assure that the packet length digged from the actual packet
1829 is something sensible in the silc_packet_decrypt_rest_special
1830 in lib/silccrypt/silcpacket.c.
1832 * Free and NULL the allocated pointer in silc_hmac_alloc if
1833 the HMAC allocation fails. The affected file is
1834 lib/silccrypt/silchmac.c.
1836 * Print the selected security properties to the log files in
1837 the server. Affected file silcd/protocol.c.
1839 * Add SKE's reference counter even if calling the completion
1840 callback manually. Otherwise it goes negative, although it
1841 does not cause any problems. The affected file is
1842 lib/silcske/silcske.c.
1844 * Remove the client entry with short timeout after giving the
1845 KILL command. Affected file lib/silcclient/command.c.
1847 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1848 case all found clients are already disconnected (WHOWAS would
1849 found them) in the server. Affected file silcd/command.c.
1851 * Update the last_receive (time of last data received) to be
1852 updated only when received private or channel message so that
1853 the idle time showed in WHOIS makes more sense.
1855 * Added boolean field `valid' in to the SilcClientEntry in the
1856 client library to indicate whether the entry is valid or not.
1857 This fixes the nickname change bug on channel when changing
1858 the nickname to be same than the old (like nick to Nick) the
1859 nickname formatter doesn't set the new nick anymore to Nick@host.
1860 Affected file lib/silcclient/idlist.[ch].
1862 * Now actually fixed the nickname changing on disconnection.
1863 Added new function silc_change_nick to the Irssi SILC Client.
1864 Affected file irssi/src/silc/core/client_ops.c,
1865 irssi/src/silc/core/silc-nicklist.[ch].
1867 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Check that the public key exists in the GETKEY command before
1870 trying to encode it. Affected file silcd/command.c.
1872 * Print some notifications on received public keys with GETKEY
1873 command in the Irssi SILC Client. Affected files are
1874 irssi/src/fe-common/silc/module-formats.[ch],
1875 irssi/src/silc/core/client_ops.c.
1877 * Use IDENTIFY command to resolve the server information in the
1878 GETKEY command instead of INFO command. Affected file
1879 lib/silcclient/command.c.
1881 * All command reply functions in the client library now calls
1882 the pending command reply callbacks even if an error has
1883 occurred. The server has done this a long time and now it was
1884 time to move the client library to this as well. Now all
1885 errors can be delivered back to the pending command reply
1886 callbacks if necessary. Affected files are
1887 lib/silcclient/command[_reply].[ch].
1889 * Change the nickname on disconnection back to the username
1890 because in reconnect the server will enforce it to it anyway.
1891 Affected file irssi/src/silc/core/silc-servers.c.
1893 * Fixed a config file parsing bug in the Irssi SILC client.
1894 Affected file irssi/src/silc/core/clientconfig.c.
1896 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * When printing the channel mode on JOIN, verify that the
1899 channel key and channel's HMAC are valid. Affected file
1900 irssi/src/silc/core/client_ops.c.
1902 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1905 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1906 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1908 * Removed channel key rekey task deleting from the function
1909 silc_server_save_channel_key. Affected file silcd/server.c.
1910 Added explicit timeout task context instead that is used to
1911 delete the task if we are registering a new task before the
1912 new task has elapsed.
1914 * When channel key rekey occurs the client library now saves
1915 the old channel key for a short period of time (10 seconds) and
1916 is able to use it in case some is still sending channel
1917 messages encrypted with the old key after the rekey. Affected
1918 file lib/silcclient/[idlist.h|client_channel.c].
1920 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Added check to the silc_server_new_id_real to not accept
1923 new ID if it is the sender's own ID. Affected file is
1924 silcd/packet_receive.c.
1926 * Assure that we do not announce ourself or the one we've
1927 sending our announcements when we're router and are announcing
1928 servers to our primary router. Affected file silcd/server.c.
1930 * Fixed silc_server_command_identify_check_client to assemble
1931 correct WHOIS packet. It send corrupted WHOIS packet and
1932 caused problem with router to router connections. Affected
1933 file silcd/command.c.
1935 Fixed also silc_server_command_whois_check the same way
1936 as for the IDENTIFY command.
1938 * Added new SilcIDListStatus to the server in the SilcIDListData
1939 structure. The status now includes the current status of
1940 the entry (like registered, resolved etc.). Affected file
1941 silcd/idlist.[ch]. Defined a bunch of different status types
1942 as well. This replaced the old boolean registered field as well.
1944 Added resolve_cmd_ident field to the SilcClientEntry structure
1945 too so that if the entry is for example being resolved so
1946 another command may attach to the same pending command reply
1947 without requiring to resolve the same entry again. This concept
1948 should optimize the WHOIS and the IDENTIFY resolving under
1949 heavy load by taking away unnecessary resolving for entries
1950 that are being resolved already.
1952 Added support for adding multiple pending commands for one
1953 command idenfier. Affected file silcd/command[_reply].[ch].
1955 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1956 before deleting the data. Otherwise the hash table will have
1957 freed data in comparison functions. Affected file is
1958 silcd/command_reply.c.
1960 * Fixed silc_idlist_replace_client_id to add the new entry to
1961 the cache with NULL nickname. Otherwise there will be invalid
1962 memory as the nickname after the nickname is freed. Affected
1963 file silcd/packet_receive.c.
1965 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1966 saved into wrong slots because the previous number of entries
1967 was not taken into account. Affected file silcd/idlist.c.
1968 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1970 * If we are router and we receive JOIN notify to a channel that
1971 does not have any users then notified client is marked as the
1972 channel founder, as it is it. The affected file is
1973 silcd/packet_receive.c
1975 * Added to the extended hash table API's table_del_*ext functions
1976 the destructor as argument too, so that the caller can decide
1977 which destructor to use or whether to use destructor at all.
1978 Affected file lib/silcutil/silchashtable.[ch].
1980 * Fixed ID Cache purging. It actually deleted the entries from
1981 the hash table after the data was freed. The hash table ended
1982 up comparing freed memory. The affected file is
1983 lib/silccore/silcidcache.c.
1985 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Fixed Irssi SILC client's KILL command's HELP syntax.
1989 * The USERS command now resolves the detailed user information
1990 if the userinfo field is missing. Affected file is
1991 lib/silcclient/command_reply.c.
1993 * Do not print error in silc_file_read if the read file does
1994 not exist. Just silently return NULL. Affected file is
1995 lib/silcutil/silcutil.c.
1997 * Fixed the silc_log_output to not wine about NULL filename
1998 and to not create some bogus " " filename. Affected file is
1999 lib/silcutil/silclog.c.
2001 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Fixed various printing bugs on the user interface in the
2004 Irssi SILC Client. Minor changes that were forgotten from
2007 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Fixed the configure.in.pre and the compilation and distribution
2010 environment to support the new autoconf 2.52. That version is
2011 now required to compile the CVS trunk.
2013 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2016 to generally parse user@fqdn format strings. Affected file
2017 lib/silcutil/silcutil.c.
2019 * Added nickname_format and nickname_force_format fields to the
2020 SilcClientParams structure. The first one defines the format
2021 for the nicknames that the library will enforce if the receives
2022 multiple same nicknames. The second one is boolean value and
2023 can be used to force the library to always enforce the format
2024 to the nicknames regardles whether there are multiple nicknames
2025 or not. This configurable formatting was employed to flexibly
2026 support accessing multiple nicknames from the user interface.
2027 The userinterface can now set the nicknames to what ever format
2028 they prefer. Affected file lib/silcclient/silcapi.h.
2030 Added function silc_client_nickname_format to the file
2031 lib/silcclient/idlist.c. It performs the nickname formatting.
2033 Added new field `hostname´ to the SilcClientEntry context.
2034 It holds the hostname of the client. Affected file is
2035 lib/silcclient/idlist.h.
2037 * Irssi SILC Client sets the nicknames in nick@hostn format.
2038 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2039 irssi/src/silc/core/silc-core.c.
2041 The WHOIS printing now also shows both the real nickname and
2042 the formatted nickname so that user knows how to access the
2043 user if there are multiple same nicknames cached. Affected
2044 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2045 printing formatting too to take the hostname now as a separate
2046 argument. The Affected file is
2047 irssi/src/fe-common/silc/modules-formats.[ch].
2049 * Changed the silc_client_get_clients_local to accept the formatted
2050 nickname as argument. It accepts the real nickname too but the
2051 formatted nickname can be used to find the true entry from
2052 multiple entries. Affected file lib/silcclient/silcapi.h and
2053 lib/silcclient/idlist.c.
2055 * Added nickname_format_parse field to the SilcClientParams.
2056 It is a callback function provided by the application to parse
2057 the nickname out of the formatted nickname string. The library
2058 calls it to get the nickname from the formatted string. Since
2059 the application generally knows better the format of the nickname
2060 string it parses it instead of the library, even though library
2061 encodes the formatted string. If the callback function is not
2062 provided then the library will use the string as is. The
2063 affected file is lib/silcclient/silcapi.h.
2065 * All the nickname strings passed to the client library in
2066 commands are now expected to be formatted nickname strings.
2067 If the command does not support the formatted nickname string
2068 it will assume that the sent string is the actual nickname.
2069 Affected file lib/silcclient/command.c.
2071 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Added public key authentication support to OPER and SILCOPER
2074 commands in the client library. Affected file is
2075 lib/silcclient/command.c.
2077 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Changed the get_auth_methdod client operation to be asynchronous.
2080 It can be async if the application resolves the authentication
2081 method from the server during the negotiation. Added new
2082 SilcGetAuthMeth completion callback that the application will
2083 call after resolving the authentication method.
2085 Added function silc_client_request_authentication_method that
2086 the application can use to resolve the authentication method
2087 from the server. Added also SilcConnectionAuthRequest callback
2088 that the library will call after the server has replied. The
2089 application can call this function if it does not know the
2090 current authentication method.
2092 Affected files are lib/silcclient/client.c and
2093 lib/silcclient/silcapi.h.
2095 * The Irssi SILC client now automatically resolves the authentication
2096 method incase any configuration information is not present (and
2097 currently there never is). The affected file is
2098 irssi/src/silc/core/client_ops.c.
2100 * Fixed public key authentication from the client library.
2101 Affected file lib/silcclient/protocol.c. Changed also the
2102 protocol specification about the public key authentication in
2103 the connection authentication protocol. The actual data to be
2104 signed is now computed with a hash function before signing.
2106 * Fixed the public key authentication from the server as well.
2107 Affected file silcd/protocol.c.
2109 * Removed the mlock()'s from the memory allocation routines.
2110 Affected file lib/silcutil/silcmemory.c. The ./configure does
2111 not check anymore for the mlock(). Affected file is
2114 * Fixed USERS command in server to allow the execution of the
2115 command for private and secret channels if the client sending
2116 the command is on the channel. Affected file silcd/command.c.
2118 * Fixed silc_client_get_clients_local to return the clients
2119 count correctly. It could return wrong value. Affected file
2120 lib/silcclient/idlist.c.
2122 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2124 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2125 types. The assembler optimizations seemed not to like 64-bit
2126 data types. The assmebler optimizations thus are now enabled
2127 also for BSD systems as opposed to only enable them for Linux.
2129 * Do not check for threads at all on BSD systems. Affected
2130 file configure.in.pre.
2132 * Removed -n and -h options from the Irssi SILC Client since
2133 they are not used in silc.
2135 * Fixed the prime generation to assure that the first digit
2136 of the generated random number is not zero since our conversion
2137 routines does not like number strings that starts with zero
2138 digit. If zero digit is seen the random number is regenerated.
2139 This caused some corrupted RSA keys when the zero first digit
2140 was met. Affected file lib/silcmath/silcprimegen.c.
2142 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Fixed WIN32 configuration in the ./configure script.
2145 Fixed to include xti.h on environments that has it.
2146 Patches by Carsten Ilchmann and andrew.
2148 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Changed the silc_id_create_client_id to be collision
2151 resistant. It is now assured that there cannot be created
2152 two same client ID's. I suspect that some weird bugs in
2153 the server were actually caused by duplicate Client IDs.
2154 Affected file silcd/serverid.[ch]. A router receiving
2155 new ID now also assures and informs the sending server
2156 if the ID caused collision.
2158 * Changed the silc_id_create_channel_id to also assure that
2159 there are no collisions.
2161 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Statement about ignoring the Mutual Authentication flag when
2164 performing rekey with PFS was a bit misleading. It is ignored
2165 if it was set in the initial negotiation, it cannot be even
2166 set in the rekey. Fixed in the ke-auth draft. Started the
2167 new versions of the protocol drafts in the doc/.
2169 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Fixed a bug in silc_client_command_identify_save when saving
2172 new channel information. The channel name was no duplicated
2173 and caused crash on exit. Affected file is
2174 lib/silcclient/command_reply.c.
2176 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Fixed the getkey command handling in the server. Send just
2179 empty OK reply to the sender if the key could not be fetched
2180 (but everything else was ok, like the key just was not available).
2181 Changed the public key parameter to optional in the protocol
2182 specs so that empty OK reply can be sent. Affected file
2185 Added a message to Irssi SILC client to tell to user if the
2186 server did not return a public key.
2188 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Fixed a channel key regeneration bug. It registered new
2191 timeout tasks exponentially until all system resources were
2192 used. Affected file silcd/server.c.
2194 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added the SILC Document generator to the scripts/silcdoc.
2197 It can be used to generate the Toolkit Reference Manual out
2198 of the source tree. Internally it will also use the RoboDoc
2199 generator now imported in util/robodoc.
2201 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Added couple of return's in rekey protocol if error orccurred
2204 during the protocol. The execution must be terminated.
2205 Affected file silcd/protocol.c. Also, terminate the protocol
2206 always with timeout.
2208 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * The client's Client ID was created initally from the wrong
2211 nickname (it could have been in format nick@host) in the
2212 silc_server_new_client. Affected file silcd/packet_receive.c
2214 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Added some SILC_LOG_ERROR's to various error conditions
2217 if client could not be added to ID cache. Affected files
2218 silcd/packet_receive.c and silcd/server.c.
2220 * When client's sock->user_data is freed, NULL also the
2221 client->router and client->connection pointers. Added check
2222 for these pointers being NULL to various places around the
2223 code. Affected file silcd/server.c.
2225 * Added client->data.registered == TRUE checks to various
2226 places around the code to assure that unregistered client's
2227 are not handled when it is not allowed. Affected file
2230 * Added `bool registered' fields to all
2231 silc_idlist_[server|client]_get_* routines to indicate whether
2232 the fetched client needs to be registered or not. Affected
2233 file silcd/idlist.[ch].
2235 * Add your own entry as registered to the ID cache in the
2236 server. Affected file server.c.
2238 * Fixed a bug in silc_server_new_server. The SilcServer was
2239 set as the new server's context instead of SilcServerEntry.
2240 This naturally caused some weird bugs.
2242 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Do not delete the channel rekey task when adding it
2245 for in silc_server_create_channel_key.
2247 * Changed the silc_server_create_channel_key to return
2248 TRUE or FALSE to indicate the success of the channel key
2251 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed MSVC++ project files and added missing files to
2254 Makefiles under win32/.
2256 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Do not add TCP_NODELAY flag if the operating system
2259 does not have it defined. Affected files are
2260 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2262 * Fixed buffer overflow from Irssi SILC Client. Affected
2263 file irssi/src/fe-common/core/themes.c.
2265 * Fixed double free in client library in the file
2266 lib/silcclient/client.c when disconnecting from server.
2268 * Applied double free patch from cras to Irssi SILC client.
2269 Affected files irssi/src/core/[modules/expandos].c
2271 * Fixed the disconnection handling to Irssi SILC Client.
2272 The application must call silc_client_close_connection
2273 in ops->connect client operation in case of failure of
2274 the connection. Affected file is
2275 irssi/src/silc/core/client_ops.c.
2277 * Do not set sock->protocol to NULL in the function
2278 silc_client_close_connection after executing the protocol's
2279 final callback since the sock might not be valid anymore.
2280 Affected file lib/silcclient/client.c.
2282 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Do not enable SILC_THREADS if the linking with libpthread
2285 did not happen. Affected file configure.in.pre.
2287 * Added notion to protocol specification that server must
2288 verify the sent authentication payload with CMODE when
2289 setting the channel founder key. Implemented it to the
2290 server. Affected file silcd/command.c.
2292 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Added _EXTRA_DIST SILC distribution variable to the
2295 distributions file. It is used to conditionally add extra
2296 files or directories to the specific distribution. Affected
2297 files ./prepare, Makefile.am.pre and distributions.
2299 Removed the `_' from the start of the distribution names.
2302 * Added README.WIN32 for instructions to compile the Toolkit
2305 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Fixed a double free in disconnection in the server. Affected
2308 file is silcd/server.c.
2310 * Fixed the lib/silcske/groups.c to work now also with GMP
2311 MP library. The string conversion did not work when using
2312 specific base and the base is indicated in the string as well.
2314 * Created win32/ directory which now includes MSVC++ specific
2315 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2316 It will appear only in the toolkit distribution
2318 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Changed the key material distribution function in case when
2321 the hash output is too short. The data is now concatenated
2322 a bit differently than it used to. Made the change to the
2323 SKE protocol specification.
2325 * Added better GMP detection to configure.in.pre. A patch
2328 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Fixed a minor bug in SKE that might cause some problem on
2331 some platforms. Affected file lib/silcske/silcske.c.
2333 * Added the cookie checking for initiator in the SKE. It checks
2334 that the responder returns the sent cookie unmodified. The
2335 affected file is lib/silcske/silcske.c. Added new SKE
2336 error type INVALID_COOKIE that can be sent during the
2337 negotiation. Fixed some memory leaks as well.
2339 * Added the "invalid cookie" error message to Irssi SILC client's
2342 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Added `task_max' field to the SilcClientParams to indicate
2345 the maximum tasks the scheduler can handle. If set to zero,
2346 default values are used. Affected file lib/silcclient/silcapi.h.
2348 * Fixed memory leaks in silc_client_close_connection. Affected
2349 file lib/silcclient/client.c.
2351 * Added silc_client_del_client_entry to client library to free
2352 all memory of given client entry. Affected file is
2353 lib/silcclient/idlist.[ch].
2355 * Added new functions silc_client_del_channel and
2356 silc_client_del_server to delete channel and server entries.
2357 Affected file lib/silcclient/[silcapi.h/idlist.c].
2359 * Removed silc_client_del_client_by_id from silcapi.h.
2361 * Fixed the INFO command to return the server's own info
2362 correctly when querying by Server ID. Affected file is
2365 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Removed the non-blocking settings in WIN32 code in the
2368 silc_sock_[read/write] and added SleepEx instead. Affected
2369 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2370 of input data is now checked with FIONREAD and ioctlsocket.
2372 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Call silc_schedule_task_del_by_context in the
2375 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2376 Affected file lib/silccore/silcprotocol.c.
2378 * Call silc_protocol_cancel for active protocols in the
2379 silc_server_close_connection if the funtion
2380 silc_server_free_sock_user_data has not been called.
2381 Affected file silcd/server.c.
2383 * Generic tasks cannot be deleted using the del_by_fd
2384 task deleting function since generic tasks does not match
2385 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2387 * Added a notion to SILCOPER help file that the SILCOPER works
2388 only on router server, not on normal server.
2390 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Added for WIN32 support for the new scheduler as well.
2393 Affected file lib/silcutil/win32/silcwin32schedule.c.
2395 * Fixed the SHA1 implementation to work on various platforms.
2397 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2400 API. It is part of the scheduler now. Everything else is
2401 as previously but some functions has changed their names.
2402 Checkout the lib/silcutil/silcschedule.h for the interface.
2403 Updated all applications to use the new interface. Affected
2404 files are lib/silcutil/silcschedule.[ch].
2406 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Found a bug in the SKE implementation. The HASH value,
2409 specified by the protocol, was not computed correctly. The
2410 public key of the responder was not added to the computation
2411 even though it is mandatory. Affected file lib/silcske/silcske.c.
2412 This unfortunately causes incompatibilities with older
2413 clients and servers.
2415 * Added WIN32 specific network init and uninit functions:
2416 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2417 the Winsock2. Affected file lib/silcutil/silcnet.h and
2418 lib/silcutil/win32/silcwin32net.c.
2420 * Set the socket always to nonblocking mode on WIN32 after
2421 reading data or writing data. Affected file is
2422 lib/silcutil/win32/silcwin32sockconn.c.
2424 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Fixed various compilation problems under WIN32. Affected
2427 files lib/silcutil/win32/silcwin32thread.c and
2428 lib/silcutil/win32/silcwin32schedule.c.
2430 * Removed all _internal.h #includes from public header
2431 files. Internal headers must never be included from
2434 Removed also the lib/silcske/payload_internal.h file.
2436 * All include files that may be needed (public and some others
2437 included by the public headers) by application developers are
2438 now copied to the ./includes directory. It does not copy any
2439 internal headers. Affected file Makefile.defines.pre and all
2440 Makefile.am's under lib/ and subdirs.
2442 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Do not change the ~/.silc directory's permissions automatically.
2445 Affected file irssi/src/silc/core/clientutil.c.
2447 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Do not cancel the protocol in silc_server_close_connection
2450 it might cause recursion. Now cancelled in the function
2451 silc_server_free_sock_user_data. Affected file silcd/server.c.
2453 * Fixed the silc_server_remove_clients_by_server to regenerate
2454 the channel keys correctly finally. Added also new function
2455 silc_server_remove_clients_channels to actually do it.
2456 Affected file silcd/server.c.
2458 * Fixed the silc_server_new_channel to not crash by giving
2459 wrong router to the new channel. Affected file is
2460 silcd/packet_receive.c.
2462 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2465 which is given as argument to the silc_client_alloc now.
2466 It can be used to configure the client and set various parameters
2467 that affect the function of the client.
2469 * The USERS command in server did not check whether the channel
2470 is private or secret. Affected file silcd/command.c.
2472 * Added new argument to the USERS command in protocol specification.
2473 The USERS command now can take the channel name as argument
2474 as well. Added support for this in client and server and
2475 updated the protocol specs.
2477 * Completed the GETKEY command in client. It can be now used
2478 to fetch also servers public key not only some clients.
2479 Affected files lib/silcclient/command[_reply].c.
2481 * Added silc_client_get_server to return server entry by the
2482 server name. Affected files lib/silcclient/silcapi.h and
2485 * Redefined the IDENTIFY command in protocol specification to be
2486 more generic. It now can be used to query information about
2487 any entity in the SILC Network, including clients, servers and
2488 channels. The query may be based either the entity's name
2489 or the ID. Added support for this in both client and server.
2491 Affected files silcd/command.c and lib/silcclient/command.c
2492 and command_reply.c.
2494 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2495 the _from_client and _from_server functions. Affected file
2498 * Added silc_client_get_channel_by_id_resolve to the file
2499 lib/silcclient/silcapi.h to resolve channel information by
2500 its ID. Added also silc_client_get_channel_by_id that
2501 does not resolve it from the server.
2503 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Added SilcServerEntry context into the client library
2506 to represent one server. The INFO command now allocates
2507 these to save the resolved server info. For now on the
2508 client library will also keep information about servers,
2509 connected and resolved with INFO.
2511 The INFO command now allocates the SilcServerEntry context
2512 and saves the server info there. The COMMAND_REPLY in
2513 the INFO now returns the parameters to application in
2514 same order as defined in the protocol specification.
2516 The entries are cached in the client->server_cache.
2518 * The INFO command is now issued after received the Client ID
2519 from the server. Affected file lib/silcclient/client.c.
2521 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2522 to the application as the mode changer might be server.
2523 It is guaranteed that NULL is not returned anymore to the
2524 application. Affected file lib/silcclient/client_notify.c.
2526 The ID Type is now also passed to the application so that
2527 it can check whether the returned entry is SilcClientEntry
2530 Added new function silc_client_get_server_by_id to return
2531 the server entry by ID. Affected files are the
2532 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2534 * Do not create the channel in the Irssi SILC Client when issuing
2535 the JOIN command but when received the sucessful JOIN command
2536 reply. Otherwise the channel might get created even though we
2537 could not join it. The Affected file is
2538 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2540 * Fixed a channel joining bug in router. The router must also
2541 check the channel modes, invite and ban lists etc. when serving
2542 the JOIN command sent by normal server. Affected file is
2543 silcd/command.c. The router now resolves the client's
2544 information from the server who sent the JOIN command if it
2545 does not know it, and processes the JOIN command only after
2548 * Changed the SilcCommandCb to take new argument; void *context2.
2549 Affected file lib/silccore/silccommand.h
2551 The second argument in the command callbacks in the server now
2552 includes the SilcServerCommandReplyContext if the command was
2553 called as pending command callback from the command reply.
2554 Otherwise it is NULL. When called as pending the status of the
2555 command reply will be checked and if it was erronous the
2556 error will be sent to the original sender of the command.
2557 This way the client always receives the error messages even
2558 though the server was actually the one who received the error
2559 when it resent the command to router, for example. Affected
2560 files silcd/command[_reply].[ch].
2562 * Fixed sending WHOWAS command's error message to client if
2563 the requested client could not be found. It was missing.
2566 * Changed the CMODE and CUMODE commands reply arguments in the
2567 protocol specification. The Channel ID is now sent in both
2568 of the commands to identify the channel. Implemented this
2569 new feature to the client and server. Affected files
2570 lib/silcclient/command_reply.c and silcd/command.c.
2572 * Made better checks for invite and ban lists in the JOIN
2573 command in server. Affected file silcd/command.c.
2575 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * The server now performs the incoming host IP/DNS lookup
2578 using the silc_socket_host_lookup and thus does not block
2579 the server anymore. Affected file silcd/server.c.
2581 * Completed the multi-thread support for SILC Scheduler in
2582 the lib/silcutil/silcschedule.c.
2584 * Fixed the configure.in.pre to detect the pthread correctly
2587 * Fixed a deadlock in silc_task_queue_wakeup in the file
2588 lib/silcutil/silctask.c.
2590 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Added new function silc_schedule_wakeup that is used in
2593 multi-threaded environment to wakeup the main thread's
2594 schduler. It needs to be used when a thread adds a new task
2595 or removes a task from task queues. After waking up, the
2596 scheduler will detect the task queue changes. If threads
2597 support is not compiled in this function has no effect.
2598 Implemented the wakeup mechanism to both Unix and WIN32
2599 systems. Affected files are lib/silcutil/silcschedule.[ch],
2600 lib/silcutil/unix/silcunixschedule.c and the
2601 lib/silcutil/win32/silcwin32schedule.c.
2603 * Added new function silc_task_queue_wakeup to wakeup the
2604 scheduler by the specified task queue. Affected file
2605 lib/silcutil/silctask.[ch].
2607 * The silc_socket_host_lookup_start now wakes up the scheduler
2608 after adding the timeout task. Affected file is
2609 lib/silcutil/silcsockconn.c.
2611 * The silc_socket_host_lookup is synchronous now if the threads
2612 support is not compiled in. However, the callback is still
2613 called asyncronously through the scheduler, anyway. Affected
2614 file lib/silcutil/silcsockconn.c.
2616 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2618 * Added new function silc_socket_host_lookup to perform
2619 asynchronous IP and FQDN lookups for the socket connection.
2620 Affected files lib/silcutil/silcsockconn.[ch].
2622 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2625 that may or may not compile the mutex support in.
2627 Changed the silc_mutex_alloc interface. It allocates the
2628 mutex now to the sent pointer and returns TRUE or FALSE.
2630 Affected file lib/silcutil/silcmutex.h.
2632 * Wrote the SILC Task Queue interface to support multi-threads.
2633 Affected file lib/silcutil/silctask.[ch].
2635 * Wrote the SILC Scheduler to support multi-threads. Affected
2636 file lib/silcutil/silcschedule.c.
2638 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2641 in lib/silcutil/win32/.
2643 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2645 * Defined SILC Mutex API and SILC Thread API and implemented
2646 them for Unix. Affected files are
2647 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2648 lib/silcutil/unix/silcunixmutex.c and
2649 lib/silcutil/unix/silcunixthread.c.
2651 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Fixed the silc_server_remove_clients_by_server's channel
2654 key re-generation. The hash table handling was incorrect
2655 and would not work with many channels. Affected file is
2658 * Fixed some memory leaks around the server code.
2660 * Rewrote the silc_server_get_users_on_channel to support IPv6
2661 based Client ID's. Affected file silcd/server.c.
2663 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2664 specification. However, a separate document must be written
2665 to define the detailed signing procedure and the payload
2666 associated with the flag. Defined the flag to the
2667 lib/silccore/silcchannel.h as well.
2669 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Changed the dynamic tables to static size tables in the
2672 lib/silccrypt/silchmac.c.
2674 * Removed GCC dependencies from the code. A patch by cras.
2676 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Do not show the error "Error receiving packet bla bla"
2679 in server if it really was not an error (-2 means that reading
2680 is pending). Affected file silcd/server.c.
2682 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Fixed a possible crash in silc_server_remove_clients_by_server
2685 in silcd/server.c. Fixed there also some memory leaks.
2687 * Fixed the silc_idlist_replace_client_id. It could replace
2688 wrong key in the hash table. Affected file silcd/idlist.c.
2690 * Do not check whether there are global users on the channel
2691 if the channel->global_users is FALSE. Affected functions
2692 silc_server_remove_from_one_channel and
2693 silc_server_remove_from_channels in silcd/server.c. Also,
2694 do not check if the removed client is local as we can be
2695 sure that global client was not removed from the channel
2696 and checking for global users is not needed.
2698 * The silc_server_remove_clients_by_server now re-generates
2699 the channel keys correctly for those channels that had
2700 clients removed from them. Affected file silcd/server.c.
2702 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Found the reason of random crashes in the server. We weren't
2705 ignoring the SIGPIPE signal (which can be sent in write())
2706 and it crashed the server. Affected file silcd/silcd.c.
2708 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Assure that sock->user_data is not NULL in the function
2711 silc_server_packet_send in silcd/packet_send.c.
2713 * Disconnect the remote connection if it could not be added
2714 to any ID lists in the server. The affected file is
2717 * Check in silc_server_packet_send[_real/dest] that the
2718 socket is not disconnecting and ignore the data if it is.
2719 Affected file silcd/packet_send.c.
2721 * Define inline to __inline on native WIN32 compilation.
2722 Affected file includes/silcwin32.h.
2724 * Added some explicit type casts for inline code since MSVC
2725 require them. Affected files lib/silcutil/silcbuffer.h,
2726 lib/trq/silcdlist.h and lib/trq/silclist.h.
2728 * Print warning in log files from now on if the packet
2729 decryption fails. Affected file silcd/server.c.
2731 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Changed the `say' client operation's interface to accept
2734 new `type' argument to indicate the type of the message sent
2735 by the library. The application may filter the library's
2736 messages according the type. The affected file is the
2737 lib/silcclient/silcapi.h.
2739 * Added two new functions to lib/silcclient/silcapi.h:
2740 silc_client_del_client and silc_client_del_client_by_id.
2741 Affected file lib/silcclient/idlist.c.
2743 * Moved the clientincludes.h from includes/ to silc/ and
2744 serverincludes.h from includes/ to silcd/.
2746 * The modes for the CMODE and CUMODE are now passed as
2747 uint32 for application with COMMAND_REPLY. The affected
2748 file is lib/silcclient/command_reply.c.
2750 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * /WHOIS without arguments shows client's own information.
2753 Affected file lib/silcclient/command.c.
2755 * Changed PING to not accept any arguments. The specs
2756 says that client can ping only the connected server so
2757 requiring an argument is not needed. Affected file is
2758 lib/silcclient/command.c.
2760 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Fixed a fatal bug in private message sending and reception
2763 encryption and decryption when using private message keys.
2764 The implementation was incorrect and did not follow the
2765 specification. It causd that some of the message were
2766 lost since it did not use the sending and receiving keys
2767 as the protocol suggests. This has been fixed and will cause
2768 incompatibilities with older clients when sending private
2769 message encrypted with private message keys. Affected files
2770 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2771 and various other in Irssi SILC Client.
2773 Added `responder' boolean argument to the functions
2774 silc_client_add_private_message_key[_ske] to indicate when
2775 the key is added as responder or initiator of the key
2778 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Removed the silc_ske_check_version function and created
2781 a SilcSKECheckVersion callback. Added also a function
2782 silc_ske_set_callbacks that is now used to set all SKE
2783 callbacks. The callback functions are not given to
2784 the SKE functions anymore, but this function is used to
2787 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2789 * Added `silc_version' argument to the silc_client_alloc
2790 to define the version of the application for the library.
2791 The library will use the version string to compare it
2792 against the remote host's (usually a server) version
2793 string. Affected file lib/silcclient/silcapi.h
2795 * Added the KE protocol context to Key Agreement context
2796 in client library so that we can abort the SKE if it
2797 is in process when we get timeout. Affected file is
2798 lib/silcclient/client_keyagr.c.
2800 * Do not resolve the client ID forever if it returns in the
2801 first time that such client does not exist. This was done
2802 for example with private message. Affected file is
2803 lib/silcclient/client_prvmsg.c.
2805 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Do not add regex.h for WIN32. The affected file
2808 includes/silcincludes.h.
2810 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2811 not work yet 100%. It generates the DLL's automatically
2812 when compiling with --with-win32 under cygwin.
2814 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * lib/contrib/regex.c is not compiled on WIN32.
2818 * Added silc_net_get_socket_opt function to the
2819 lib/silcutil/silcnet.h.
2821 * Added includes/silcwin32.h for WIN32 specific includes
2824 * Do not use ptime structure or any of the posix process
2825 functions on WIN32 in lib/silccrypt/silrng.c.
2827 * Added silc_gettimeofday to provide generic function
2828 for struct timeval on all platforms. Added the function
2829 to lib/silcutil/silcutil.h.
2831 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2834 library as they clearly belong there. As a plus side we
2835 can make the actual socket connection routines platform
2838 Added also new generic function silc_socket_read and
2839 silc_socket_write (that used to be silc_packet_[read/write].
2840 The implementation of these are platform specific.
2842 * Added WIN32 specific routines of silc_socket_[read/write]
2843 to lib/silcutil/win32/silcwin32sockconn.c.
2845 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Added preliminary support for native WIN32 compilation under
2848 cygwin (using the -mno-cygwin option for GCC) to the
2849 ./configure.in.pre. The --with-win32 now prepares the
2850 compilation for native WIN32.
2852 * Rewrote the SILC Scheduler interface in the file
2853 lib/silcutil/silcschedule.h. The scheduler is now context
2854 based and does not have anymore any global static scheduler.
2855 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2856 and created lib/silcutil/win32 directory for WIN32 based
2859 * Added Unix specific network routines to the
2860 lib/silcutil/unix/silcunixnet.c and the old
2861 lib/silcutil/silcnet.c includes now only generic routines.
2863 Added WIN32 specific network routines to the
2864 lib/silcutil/win32/silcwin32net.c.
2866 * Added Unix specific utility functions from the
2867 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2869 * Added WIN32 SILC Scheduler to the file
2870 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2873 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Do not handle JOIN notify in the server if the target client
2876 is not registered (idata->registered == FALSE). The affected
2877 file is silcd/packet_receive.c.
2879 * Update the nickrec->founder in event_cumode in the Irssi SILC
2880 client. Affected file irssi/src/silc/core/silc-channels.c.
2882 * Fixed the CUMODE_CHANGE notify handling in the server when
2883 server and router are announcing their clients on channels.
2884 Now the mode changes are saved and notified correctly. The
2885 affected file is /silcd/packet_receive.c.
2887 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2888 They really did not replace the cache entry in the ID Cache.
2889 Now they do that. Affected file silcd/idlist.c.
2891 * Fixed the KICK notify handling in the Irssi SILC client to
2892 update the channel records so that the kicked client does not
2893 appear to be on the channel. The affected file is
2894 irssi/src/silc/core/silc-channels.c.
2896 * Always update the conn->current_channel when executing command
2897 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2899 * Fixed the KILL notify handling in Irssi SILC client to remove
2900 the killed client on all channels.
2902 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Fixed the silc_parse_command_line to remove extra spaces
2905 from the start and end of the arguments. Affected file is
2906 lib/silcutil/silcutil.c.
2908 * Cancel and free any active protocol in the function
2909 silc_server_close_connection. Affected file silcd/server.c.
2911 * Cancel and free any active protocol in the function
2912 silc_client_close_connction. Affected file is
2913 lib/silcclient/client.c.
2915 * Do not execute the KILL command for clients that are in
2916 history (ie. they are not in the network). Affected file is
2919 * Fixed KILL notify handling, client does not crash anymore.
2920 Affected file irssi/src/silc/core/silc-channels.c.
2922 * Reduced the default packet buffer size from 2048 to 1024 in
2923 lib/silccore/silcpacket.c.
2925 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2926 counter to the SKE context that is incresed when the SKE library
2927 performs async operation outside the library. If the outside
2928 process frees the SKE context and FREED status will be set
2929 and the library will detect after the sync operation that the
2930 libary is freed. The affected files are
2931 lib/silcske/silcske[_status].[ch].
2933 * Resolve the client entry information in the function
2934 silc_client_channel_message to assure that NULL pointer is not
2935 passed as client entry to the application. */
2937 * Fixed the task timeout calculation to assure that there is
2938 never negative timeouts. The affected file is
2939 lib/silcutil/silcschedule.c.
2941 * Fixed the channel user mode notification sending in server.
2942 It was sent point-to-point to the router (or to server by router)
2943 but it needs to be destined to a channel. The routines now
2944 supports sending the channel user mode notifys to the channels
2945 when announcing clients and channels. Affected files are
2946 silcd/server.c and silcd/packet_receive.c.
2948 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2949 It did not actually replace the old channel entry in the cache.
2950 Affected file lib/silcclient/client_notify.c.
2952 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Fixed a possible crash in silc_packet_send_prepare. It now
2955 assures always that there is enough space in the buffer and
2956 at the tail area of the buffer (for MAC).
2958 Fixed the inbound buffer reallocation in silc_packet_read.
2959 It was old code and did not handle the reallocation correctly.
2962 The affected file is lib/silccore/silcpacket.c.
2964 * Fixed buffer overflow in silc_parse_nickname in the file
2965 lib/silcutil/silcutil.c.
2967 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * make install generates new server keys only if there is not
2972 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2975 Added check that if the NOREPLY is set then we will not send
2976 the away message. This avoids infinite loop of away messages
2977 if both clients are away. The affected file is
2978 lib/silcclient/client_prvmsg.c.
2980 * Fixed client crash if /NICK was given without arguments.
2981 Affected file lib/silcclient/command.c.
2983 * Server does not send the invite list in INVITE command back
2984 to the client if the list was not altered. Added this notion
2985 to the protocol spec as well. Affected file silcd/command.c.
2987 Fixed possible crash in INVITE command by checking the
2988 value of silc_server_get_client_route command.
2990 * Fixed the INVITE notify type handling. The arguments are now
2991 taken in correct order and client does not crash. The affected
2992 file is irssi/src/silc/core/silc-channels.c.
2994 Removed the "Inviting xxx to channel" message from the
2995 client library away and let the application handle it.
2996 Affected file lib/silcclient/command.c. Added that message
2997 to Irssi SILC client's message formats.
2999 * Fixed CMODE command crash in client. It now checks the
3000 amount of arguments correctly and does not crash. The affected
3001 file is lib/silcclient/command.c.
3003 * Do not create new channel automatically in silc_channels_join
3004 but check whether the channel by that name already exists.
3005 Affected file irssi/silc/core/silc-channels.c.
3007 * Do not send the SERVER_SIGNOFF to router if the disconnected
3008 entity was the router. Affected file silcd/server.c.
3010 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3011 SILC client as it was missing from there.
3013 Added the handling of the KICK notify to the Irssi SILC client
3014 as it was missing. Added "you have been kicked" message to
3015 Irssi SILC client's message modules formats.
3017 Added the handing of the KILL notify to the Irssi SILC client
3018 as it was missing. Added the kill message module formats
3021 The affected file is irssi/src/silc/core/silc-channels.c.
3023 * The router did not save the channel mode the server announced.
3024 Affected file silcd/packet_receive.c.
3026 * Fixed a possible crash in INFO command in server. If the
3027 server did not provide the server info it crashed. Affected
3028 file silcd/command.c.
3030 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Fixed the GETKEY command in the server to check also the
3033 global list. Otherwise the GETKEY would not work correctly
3034 in normal SILC server. Affected file silcd/command.c.
3036 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Fixed GETKEY crash, it crashed if the command did not succseed.
3040 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3043 is now real and not just an macro interface to GMP.
3045 Removed the entire GMP from the source tree and imported new
3046 NSS MPI library instead. Reason for removing GMP is that it is
3047 extremely large and compiles extremely slow. The NSS MPI
3048 is only a few files and compiles in less than 10 seconds.
3049 The speed is also about the same as GMP. The MPI is imported
3050 to lib/silcmath/mpi.
3052 If the system has GMP installed we will still use the GMP.
3053 If it is not then the NSS MPI will be compiled.
3055 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Merged a long nickname (127 characters long) crash bugfix from
3058 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3060 * Merged a freed memory reference bugfix from Irssi CVS tree.
3061 Affected file irssi/src/core/commands.c.
3063 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added the server's public key sving and verification to the
3066 server when performing the SKE. This was missing and the
3067 remote server's (or router's) public key was accepted without
3068 checking whether we have it previously or trust it at all.
3069 Affected file silcd/protocol.c.
3071 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Check in the silc_server_timeout_remote if protocol is active
3074 and make sure that the protocol's final callback is called so
3075 that all memory if freed. Affected file silcd/server.c.
3077 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * silc_server_whois_send_reply crashed the server if the nickname
3080 was 127 characters long. Affected file silcd/command.c.
3082 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Added sanity check to the silc_server_new_client. If the hostname
3085 is provided inside username then check that the provided hostname
3086 really is the same as the resolved one. If the hostname was not
3087 resolved then check it from the public key. Affected file is
3088 silcd/packet_receive.c.
3090 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3091 if the server disconnected us and the connection is not valid
3092 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3094 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3095 the library to the lib/silcutil/silcutil.[ch].
3097 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Close log file after open. Affected file
3100 lib/silcutil/silclog.c.
3102 * Check whether sock == NULL in silc_client_send_packet and return
3103 if it is. Affected file lib/silcclient/silcclient.c.
3105 * Check rec->entry == NULL in the Irssi SILC Client before
3106 sending the channel message. Affecte file is
3107 irssi/src/silc/core/silc-servers.c.
3109 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Merged a splitted window bugfix from Irssi CVS tree. The
3112 affected file is irssi/src/fe-text/textbuffer-view.c.
3114 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3115 It did not print nickname.
3117 * Improved the distributions system a bit.
3119 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3122 irssi/src/fe-text/gui-window.c.
3124 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3125 to in-active server. The affected file is
3126 irssi/src/silc/core/client_ops.c.
3128 * Resolve the client in USERS command reply if the entry does
3129 not have username resolved. The affected file is
3130 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3131 command to WHOIS command to really resolve stuff. The USERS
3132 is not used any more in any critical section so WHOIS can
3133 be used even though it might be slower than IDENTIFY.
3135 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3138 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Changed the protocol API a bit more consistent in the
3141 lib/silccore/silcprotocol.[ch].
3143 * Changed the following headers to ROBODoc format:
3145 lib/silccore/silcpayload.h
3146 lib/silccore/silcprotocol.h
3147 lib/silccore/silcsockconn.h
3149 All core library headers are now formatted.
3151 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Fixed a bug in Irssi SILC client; do not show that you are
3154 server/router operator if you really are not. Affected file is
3155 irssi/src/silc/core/client_ops.c.
3157 * Renamed silc_command_free_payload to silc_command_payload_free.
3158 Affected file lib/silccore/silccommand.h
3160 * Added silcmath.h to include the prototoypes of various routines
3161 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3164 * Changed the following headers to ROBODoc format:
3166 lib/silccore/silcchannel.h
3167 lib/silccore/silccommand.h
3168 lib/silccore/silcid.h
3169 lib/silccore/silcidcache.h
3170 lib/silccore/silcmode.h
3171 lib/silccore/silcnotify.h
3172 lib/silccore/silcpacket.h
3173 lib/silcmath/silcmath.h
3175 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added checking to the server code not to start the server if
3178 ciphers and stuff are not configured properly. Affected files
3179 silcd/serverconfig.[h] and silcd/server.c.
3181 * Changed the layout of the header files of the public interfaces
3182 in the SILC libraries. The new layout supports ROBODoc
3183 documentation tool (and some others) so that it is easy to create
3184 a library reference manual. All the other headers and source
3185 code must still follow the CodingStyle document. Also source
3186 code must not include these ROBODoc stuffs, only the headers.
3187 Furthermore, all public interface headers must now be named
3188 by using `silc' prefix, example: silcapi.h, silccipher.h.
3189 Some files were renamed due to this. All the other headers
3190 must not be used as public interfaces. I will update the
3191 CodingStyle document later. Changed following headers, so far:
3193 lib/silcclient/silcapi.h

3198 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Removed silc_client_packet_send_flush from the client library
3203 as it is not needed. Affected file lib/silcclient/client.[ch].
3205 * Added printing of message of unresolved authentication method
3206 to the Irssi SILC client. Added it to the module formats.
3207 Removed the same message from the client library.
3209 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Added new distribution feature, DISTLABEL. Every distribution
3212 can define own preprocessor label that can be used in the
3213 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3214 file distributions, acconfig.h.pre and prepare.
3216 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Added Makefile.defines_int to include the actual definitions
3219 for Makefile.defines.in. Tested the new distribution system,
3220 created distributions and tested installation.
3222 * Added AWAY message printing to the Irssi SILC client. Added
3223 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3225 * Added SCONNECT command to call the SILC's CONNECT command.
3226 Cannot use CONNECT directly since Irssi uses that internally.
3227 Affected file irssi/src/silc/core/silc-servers.c.
3229 Added ACTION local command. It is same as ME command but takes
3230 the channel as mandatory argument.
3232 Rewrote some of the Irssi's help files to suite for SILC
3235 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Added Makefile.defines[.in] that should for now on be included
3238 in all Makefile.am file in the source tree. That file includes
3239 all common compilation definitions for SILC source tree.
3241 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Minor changes to the ./prepare script to change the package
3244 name according the distribution name to the configure.in.
3246 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Created new distribution system. Added file `distributions'
3249 that defines all the distributions that can be created out of
3250 the SILC source tree. The ./prepare script now reads that
3251 file to determine how to prepare the distributions. The
3252 first argument to the ./prepare is the name of the distribution
3253 and second is the version of the distribution. If given
3254 without arguments it creates the default (toolkit) distribution
3255 with the default version (defined in ./prepare).
3257 All Makefile.am files that are subject to the distributions
3258 are now named as Makefile.am.pre. These are ./Makefile.am
3259 and lib/Makefile.am. Others may be changed later.
3261 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added invite list, ban list, some key management and connection
3264 error message printing to module formats in the Irssi SILC client.
3266 * Added new silc_client_set_away_message to set the away message
3267 that is back to the person who sent private message. The
3268 affected file lib/silcclient/silcapi.h and the
3269 lib/silcclient/client_prvmsg.c.
3271 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Fixed the private message sending in the Irssi SILC client,
3274 added local command KEY to the Irssi SILC client.
3276 Added key management and key agreement message formats to the
3277 irssi/src/fe-common/silc/module-formats.[ch].
3279 Added USERS (alias WHO) printing, server/router operator
3280 indication and LIST command printing to the module formats.
3282 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Fixed channel joining notify handling, cumode notify handling
3285 from Irssi SILC client.
3287 * Added SILC specific module-formats to the Irssi SILC client so
3288 that SILC specific message hilighting, colors etc is possible.
3289 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3291 Added channel mode, channel user mode, actions, notices,
3292 whois and whowas printing to the the module-formats.c.
3294 * Fixed a bug in channel deletion in the server. The channel
3295 is not left to the cache even if the channel founder auth mode
3296 is set when there are no users anymore on the channel. Affected
3297 file silcd/server.c.
3299 * The silc_net_localhost now resolves the entire hostname including
3300 the domain name. Affected file lib/silcutil/silcnet.c.
3302 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Changed the ask_passphrase client operation to be ascynchronous.
3305 It has now a completion callback and a context that the
3306 application must call after it has got the passphrase from
3307 the user. Affected files lib/silcclient/silcapi.h,
3308 lib/silcclient/protocol.c, lib/silcclient/command.c and
3311 Added SilcAskPassphrase callback that the application calls
3312 to deliver the passphrase to the library.
3314 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3315 The public key verification and especially a certificate
3316 verification is asynchronous procedure.
3318 Added new SILC_SKE_STATUS_PENDING status to indicate the
3319 request is pending and a callback will be called to finalize
3322 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3323 indicate that remote end did not send its public key (or
3324 certificate), even though we require it. Added check for this
3325 condition in the SKE. This was a security bug, now fixed.
3327 Defined new SilcSKEVerifyCbCompletion callback that is called
3328 when the verification process is completed.
3330 The affected files lib/silcske/silcske_status.h and
3331 lib/silcske/silcske.[ch].
3333 * Changed the verify_public_key client operation to be async
3334 as well. Defined SilcVerifyPublicKey callback that is used to
3335 indicate the success of the public key verification process.
3337 Changed the server and client to use the new async client
3340 * Changed the Irssi SILC client's internal scheduler to be called
3341 twice as many times as it used to be. As a result the client
3342 should be a bit faster now. Affected file is
3343 irssi/src/silc/core/silc-core.c.
3345 * Added support to Irssi SILC client of asynchronous public key
3346 verification and passphrase inquiry. Affected file is
3347 irssi/src/silc/core/silc-core.c.
3349 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Do not say "You have left channel %s" in client library.
3352 Moved it to the application. Affected files are
3353 lib/silcclient/command.c and silc/client_ops.c.
3355 * Fixed silc_client_get_clients. Command context was not
3356 duplicated and was freed memory in the callback. Affected
3357 file lib/silcclient/idlist.c.
3359 * Do not say "you are now talking..." on JOIN command in the
3360 client library. The appliation must handle it.
3362 * Do not say ".. changed topic to" in command reply in the
3363 client libary. The application must handle it.
3365 * Fixed TOPIC command sending in the client library.
3367 * Fixed a memory leak in silc_client_command_free in the file
3368 lib/silcclient/command.c.
3370 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Imported a modified version of Irssi client to the source tree.
3373 The Irssi will be used to create a new client called
3374 Irssi SILC. Imported to irssi/.
3376 Added silc_core_init_finish function to the Irssi. Affected
3377 file irssi/configure.in.
3379 A lot changes in the Makefile.ams around the irssi tree.
3381 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Do not rehash if the new size is same as the old size of the
3384 hash table, in the silc_hash_table_rehash*. The affected file
3385 lib/silcutil/silchashtable.c.
3387 * Replaced hash_table_del_by_context calls from the server
3388 (when channel->user_list and client->channels) to the
3389 hash_table_del as it is sufficient and faster.
3391 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Added silc_hash_table_list, silc_hash_table_get and the
3394 SilcHashTableList structure to provide an alternative way to
3395 traverse the hash table. The affected files are
3396 lib/silcutil/silchashtable.[ch].
3398 * Changed the server's idlist routines to use the hash table
3399 routines to optimize the code.
3401 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Replaced the client entry's `channel' list and channel entry's
3404 `user_list' list to hash tables for optimized lookup. Changed
3405 the code to use the hash table interface around the code.
3406 Affected file lib/silcd/idlist.[ch].
3408 * Added `auto_rehash' boolean argument to the function
3409 silc_hash_table_alloc to indicate whether the hash table should
3410 auto-rehash when it thinks is appropriate time. It will
3411 increase the hash table size if the there is twice as much
3412 entries in the table than the size of the table, and will
3413 decrease the size if there are twice as less entries than
3414 the size of the table.
3416 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3420 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * silc_idcache_purge_by_context deletes the entry now by context
3423 as it is supposed to do. Affected file lib/silccore/idcache.c.
3425 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3426 client is not anymore valid (WHOWAS givens the info) and not
3427 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3429 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Removed the `data' and `data_len' arguments from the ID Cache
3432 interfaces and added `name' argument. ID Cache does not handle
3433 anymore the binary data only a names associated with given ID.
3435 * When hashing a Client ID with silc_hash_id the entire ID is
3436 not hashed anymore, instead only the hash of the Client ID is
3437 hashed. This way we can access the Client ID from the cache
3438 with Client ID but with the hash of the ID (which is a hash of
3439 the nickname) as well without any difference in performance.
3441 Added also silc_idcache_find_by_id_one_ext to do one on one
3442 searching when we have the actual ID. Added also function
3443 silc_hash_client_id_compare. The affected files are
3444 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3446 * When hashing the name associated with a ID it is always done
3447 in lowercase. This way we can access the cache without worrying
3448 about case-sensitivity, even though, for example nicknames are
3451 * Fixed a bug in server with channel message sending. It put
3452 wrong ID type as destination ID. The affected file
3453 silcd/packet_send.c.
3455 * silc_idcache_del_by_context now deletes from all hash tables
3456 by context. Affected file lib/silccore/idcache.c.
3458 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Changed the client library to use the new ID Cache interface.
3461 Changes around the source tree.
3463 * Added silc_hash_table_rehash_ext to rehash with specific
3464 hash function. Affected file lib/silcutil/silchashtable.[ch].
3466 * Added silc_hash_string_compare to compare two strings in the
3467 hash table. Affected file lib/silcutil/silcutil.[ch].
3469 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added new function silc_idcache_del_by_context into the
3472 lib/silccore/idcache.[ch].
3474 * Changed the server's ID list routines to use the new ID Cache
3475 interface. Changes around the source tree.
3477 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Added silc_hash_table_del[_by_context]_ext functions in to the
3480 lib/silcutil/silchashtable.[ch].
3482 Removed silc_hash_table_find_all* routines and added new
3483 silc_hash_table_find_foreach to replace them.
3485 Added silc_hash_table_replace_ext function as extended
3486 replacing function. Separated the simple hash table interface
3487 from the extended hash table interface in the file
3488 lib/silcutil/silchashtable.h.
3490 * Fixed minor bugs and changed it to use some of the new
3491 hash table functions in lib/silccore/idcache.c
3493 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Added new function silc_hash_table_find_all to return all keys
3496 in the hash table by the specified key. As the hash table is
3497 collision resistant it also makes it possible to have several
3498 duplicate keys in the hash table. This function may be used to
3499 find all of the keys from the hash.
3501 Added user_context arguments to the SilcHashFunction,
3502 SilcHashCompare and SilcHashDestructor to deliver user specified
3505 Added new fuctions silc_hash_table_find[_all]_ext to do
3506 extended lookup with specified hash and compare functions and
3507 specified user contexts.
3509 Added new function silc_hash_table_add_ext to add the key
3510 with specified hash function and user context.
3512 Added new function silc_hash_table_foreach to traverse all
3513 entrys in the hash table. Added SilcHashForeach callback
3516 Added new function silc_hash_table_del_by_context to delete
3517 the entry only if the context associated with the key matches.
3519 Affected files are lib/silcutil/silchashtable.[ch].
3521 * Removed silc_hash_[server/client/channel]_id and added just
3522 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3523 silc_hash_id_compare to compare two ID's using as the hash table
3524 comparison function. Added also silc_hash_data to hash
3525 binary data and silc_hash_data_compare to compare it.
3527 * Removed silc_idlist_find_client_by_hash as it is not needed
3528 anymore. Affected file silcd/idlist.[ch].
3530 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3531 to use internally the SilcHashTable. The new ID Cache is a lot
3532 faster than the old one. Some of the ID Cache interface was also
3533 rewritten and obsolete and stupid functions were removed.
3535 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Added entry_count field to the SilcHashTable to keep the number
3538 of the entries in the table. Implemented the function
3539 silc_hash_table_rehash. Added new function
3540 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3542 Fixed a minor bug in silc_hash_table_free.
3544 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3545 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3546 into the lib/silcutil/silcutil.[ch].
3548 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Implemented a collision resistant hash table into the
3551 lib/silcutil/silchashtable[ch]. See the header and the source
3552 for the SilcHashTable API.
3554 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Merged dotconf version 1.0.2 into lib/dotconf.
3558 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Do not compile anything in lib/silcsim/* if the SIM support
3561 is not enabled. The tree should now compile without problems
3564 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Compiled the SILC under cygwin. Compiled and tested briefly
3567 without problems. More tests needed. The SIMs didn't compile
3570 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3572 * Fixed possible crash in silc_get_username in the
3573 lib/silcutil/silcutil.c.
3575 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Fixed a va_arg in silc/client_ops.c.
3579 * Oops, RC5 routines were named AES and caused some problems
3580 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3582 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Added new SilcIDIP structure into the lib/silccore/id.h and
3585 replaced the old `ip' fields from all SILC ID's to that type.
3586 This is a step towards IPv6 support.
3588 The silc_id_get_len takes now the ID as an extra argument.
3589 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3590 both IPv4 and IPv6 based ID's.
3592 The affected files are lib/silccore/id.[ch] and other files
3593 around the tree using these routines.
3595 * Removed the ID length arguments in server from various
3596 silc_server_send_notify_* routines -> they are not needed
3599 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed memory leak in silc_encode_pem_file in the file
3602 lib/silcutil/silcutil.c.
3604 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Check minor version as well in the SKE. Affected files are
3607 silcd/protocol.c and lib/silcclient/protocol.c.
3609 * Added --identifier option to the server so that an identifier
3610 can be when creating the public key for the server. Affected
3611 file is silcd/silcd.c.
3613 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3614 lib/silccrypt/silcpkcs.c.
3616 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Register default ciphers and stuff when using -C option with
3619 the server. Affected file sildc/silcd.c.
3621 * Put back the servers public key filename format, it is better
3622 than the new one. For now, the client keys are saved with the
3623 new filename format. The affected file silc/client_ops.c.
3625 * Implemented the Cipher API for the rest of the ciphers that
3626 did not implement it or implemented it the wrong way.
3628 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Register default ciphers and stuff when using the -S option
3631 in the client. Affected file silc/silc.c. Same also when
3632 creating new key pair with -C option.
3634 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Fixed the silc_verify_public_key client operation function to
3637 save the public keys differently. The fingerprint is now
3638 used as filename and not the hostname. This way also the
3639 client keys are saved uniquely and not with hostnames. The
3640 affected file is silc/client_ops.c.
3642 * Trimmed the silc_hash_fingerprint function to remove extra
3643 whitespaces from the end of the fingerprint. The affected
3644 file is lib/silccrypt/silchash.c.
3648 * Added silc_cipher_register_default function to register all
3649 default ciphers. It can be used when configuration files
3650 does not exist and the application does not want any specific
3651 ciphers in any specific order.
3653 The SilcDList is now used as silc_cipher_list dynamically
3654 allocated cipher list. Removed the static list all together
3655 and now all ciphers must be allocated to the dynamic list.
3656 The silc_cipher_alloc routine was changed to check only the
3659 All silc_cipher_* routines that used to return int returns
3662 The affected files lib/silccrypt/silccrypt.[ch].
3664 * The same thing was done to silc_hash_* as for silc_cipher_*
3665 routines. Affected files lib/silccrypt/silchash.[ch].
3667 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3668 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3669 Added also silc_pkcs_[un]register[_default] functions.
3670 Removed the data_context from the PKCS API.
3672 * Added silc_hmac_register_default function to register default
3673 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3674 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3675 to unregister all hmacs at once.
3677 * Register the default ciphers, hash functions, PKCSs and HMACs
3678 if client's configuration file does not exist. The affected
3681 * The client did not load the hash functions from the SIM
3682 modules at all. Added support for this. Affected file is
3683 silc/clientconfig.c.
3685 * When decoding public key with silc_pkcs_public_key_decode, check
3686 the supported algorithm only if PKCS are registered. Affected
3687 file lib/silccrypt/silcpkcs.c. The same was done with the
3688 silc_pkcs_private_key_decode.
3690 * Fixed the SILC List routines to keep the list always in order.
3691 It used to change the list's order when traversing the list but
3692 not it preserves the order. Affected file lib/trq/silclist.h.
3694 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Added the client library to use the SilcSocketConnection's
3697 reference counter (by silc_socket_dup) to prevent the bug that
3698 the socket object may be freed underneath async operation.
3700 * The name resolv library checking fixes in the configure.in.pre.
3703 * Created new version of the protocol drafts for future
3704 development. The -03 drafts are the ones that will be changed
3705 in the trunk now and the -02 will remain as they are.
3707 * Send list of CUMODE notifys to the router when announcing
3708 the channel users to the router. Affected file silcd/server.c.
3709 If the router receiving channel founder CUMODE for a channel
3710 that already has channel founder it will send CUMODE notify
3711 to the sender to remove the channel founder rights from the
3712 announced client. Affected file silcd/packet_receive.c.
3714 * The CUMODE notify may now use Server ID as well as the entity
3715 who changes the mode. Updated protocool specs.
3717 * Updated INSTALL and README files.
3719 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * New web pages in the http://silc.pspt.fi. The pages was
3726 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Implemented the [DenyConnectin] config section in the server.
3729 Added silc_server_config_denied_conn to check whether incoming
3730 connection is denied. Affected file silcd/serverconfig.[ch].
3732 * Do not check the ports when checking the incoming configuration
3733 data if the port is 0, meaning any. Affected file is
3734 silcd/serverconfig.c.
3736 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Fixed buffer overflow in silc_string_compare in the file
3739 lib/silcutil/silcutil.c.
3741 * Fixed double free in silc_server_command_leave in the file
3744 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Fixed the version checking in the server. Affected file is
3749 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Fixed the configuration data fetching when accepting new
3752 connections in the server. Affected file silcd/server.c.
3754 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Added `sender_entry' argument to the function
3757 silc_server_packet_relay_to_channel so that we can check
3758 whether some destination actually belongs to the same route
3759 the sender belongs (ie, we must not resend the packet to the
3760 sender). Affected file silcd/packet_send.[ch].
3762 * Added `servername' field to the SilcClientEntry in the server
3763 to hold the name of the server where client is from. Affected
3764 file is silcd/idlist.h.
3766 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Moved the channel message encrypting in the router betwen
3769 router connections from silc_server_channel_message to the
3770 silc_server_packet_relay_to_channel since we want to check
3771 whether we have anybody channel before encrypting anything.
3772 Affected files silcd/packet_[receive/send].c.
3774 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Fixed the [AdminConnection] server config section to support
3777 multiple entries. Affected file silcd/serverconfig.c.
3779 * Added support into the server to check the validity of the
3780 incoming connection before executing any KE or authentication
3783 * The connection configuration is now saved to the KE and
3784 connection auth protocol contexts and not fetched anymore in
3785 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3787 * The local hosts listenning address and port is also resolved
3788 now when starting the server. We want to have the socket object
3789 to include the real address and port for the listener. Added
3790 new function silc_net_check_local_by_sock into the files
3791 lib/silcutil/silcnet.[ch].
3793 * Fixed a broadcast bug in server -> do not broadcast if we
3796 * Fixed a routing bug. Do not route broadcast packets ever.
3797 Broadcast packets must be processed always and not routed since
3798 they may be destined to some other host than yourself and thus
3799 would get routed without no good reason. Affected file is
3802 * Added function silc_server_config_is_primary_route to check
3803 whether primary router connection has been configured (a router
3804 configuration that we are initiating). If there is not, we
3805 will assume that there is only two routers in the SILC network
3806 and we will use the incoming router connection as our primary
3807 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3809 * Changed the order of the broadcasting. Broadcast _after_ the
3810 packet has been processed not before. Affected file is
3813 * Fixed a [ClientConnection] parsing bug. The port was never
3814 parsed correctly thus resulting to port 0. Affected file
3815 silcd/serverconfig.c.
3817 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3818 argument and did not set the broadcast packet flag. Affected
3819 file silcd/packet_send.c. Fixed same bug in the function
3820 silc_server_send_notify as well.
3822 * If we receive NEW_ID packet for our own ID in the server, ignore
3825 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Removed the nickname from the Private Message Payload.
3830 Updated the code and the protocol specs.
3832 * Updated protocol specs for submitting to the IETF.
3834 * Tweaked the Random Number Generator a bit. Affected file
3835 lib/silccrypt/silcrng.c. Exported a new function
3836 silc_rng_[global]_add_noise which can be used to add more
3839 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Do not parse packets with different timeout when protocol
3842 is active -> may cause problem with rekey. Affected file
3845 * When server receives signoff notify it must not create
3846 new channel key if the client is on any channels since the
3847 sender of the signoff notify will create it.
3849 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Added printing of error messages during SKE protocol from the
3852 failure packet sent by server during SKE. Affected file
3855 * Removed the client's failure_callback handling with timeout
3856 and handle it immediately when received.
3858 * The SKE library returned wrong type in SUCCESS and FAILURE
3859 packets. They must be 32 bit MSB not 16 bit MSB.
3861 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Ok, rewrote the logic of the re-key and now it seems to work.
3864 I tested it on high traffic with frequent re-keys without
3865 problems. Added hmac_receive (and renamed hmac to hmac_send)
3866 in SilcClientConnection in lib/silcclient/client.h and
3867 in SilcIDListData in silcd/idlist.h. Also, removed the
3868 SilcPacketParserContext's cipher and hmac fields as they are
3869 not needed anymore and actually caused some problems when
3870 the ciphers and hmac's changed underneath the packet parser.
3872 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * If re-key protocol is active then process the incoming packets
3875 synchronously since we must assure that icoming packets encrypted
3876 with the old key is processed before the new keys is set to
3877 use. This is true other packets than for REKEY packets.
3878 Affected file silcd/server.c. The same was done to client library
3879 as well, affected file lib/silcclient/client.c.
3881 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Fixed bug in client and server to accept the force send if
3884 the packet is send from silc_[server/client]_packet_process
3885 function. Otherwise the packets are never delivered, oops.
3887 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Disable force sending of packets when REKEY protocol is active.
3890 We must assure that no packet is sent directly when rekey is
3891 performed. All packets must be sent through packet queue.
3892 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3893 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3894 function is silc_[server/client]_packet_send_real to check
3897 * Replaced the SIM paths from example config files to
3898 /usr/local/modules. Also, make install creates now
3899 /usr/local/silc/logs directory to hold all the SILC server
3902 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Made the configure.in.pre work on Solaris. Patch by salo.
3906 * Made all ciphers compatible with non-x86 machines. Defined
3907 CBC mode macros into lib/silccrypt/ciphers_def.h.
3909 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Fixed the make install.
3913 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * When MAC computation fails the silc_packet_decrypt returned 0
3916 even though it was supposed to return -1. Fixed this. The
3917 affected file is lib/silccore/silcpacket.c.
3919 * Do not replace the config files in /etc/silc (in make install)
3920 if they already exist. Affected file ./Makefile.am.
3922 * Do not send re-key packets immediately but through packet queue.
3923 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3925 * Changed silc_net_check_host_by_sock to return FALSE if the
3926 IP/DNS could not be resolved. Though, it returns the IP address
3927 now even if it could not resolve it (but returns also FALSE).
3928 Affected file lib/silcutil/silcnet.[ch].
3930 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added silc_pkcs_decode_identifier to decode the public key's
3933 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3934 Added also silc_pkcs_free_identifier. Added also new context
3935 SilcPublicKeyIdentifier.
3937 * Added -S option to the silc client. It is used to dump the
3938 contents of the specified public key file.
3940 * Changed the PKCS api to return the public key length when
3941 setting the public key.
3943 * Fixed a fatal bug in the public and private key file loading.
3944 Affected file lib/silccrypt/silcpkcs.c.
3946 * Execute the packet parsing for client with zero (0) timeout
3947 if the protocol is active. Affected file silcd/server.c.
3949 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Made the key generation options to the silcd program. Added
3952 -C option, equivalent to client's option.
3954 * Added new [ServerKeys] config section to the server. It
3955 configures the server's public and private key.
3957 * Defined generic Public Key Payload into the protocol
3958 specification to send specific type of public keys and
3961 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3962 public key or certificate.
3964 * Implemented the GETKEY command to the server and to the
3965 client library and on user interface.
3967 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Made preliminary `make install' work.
3971 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Added SilcServerRekey context into silcd/idlist.h.
3975 * Added the PFS support as defined in the specification to the
3976 SKE protocol. Affected files lib/silcske/*.c.
3978 * Added `ske_group' field to the SilcServerRekey context to hold
3979 the number of the SKE group that is used with PFS in re-key.
3980 Affected file silcd/idlist.h.
3982 * Added PFS re-key support to the server. Affected file is
3985 * Added silc_protocol_cancel to cancel execution of the next
3986 state of the protocol. Affected file is
3987 lib/silccore/silcprotocol.[ch].
3989 * Added the re-key support with and without PFS to the client
3990 library. Re-key is performed once in an hour, by default.
3992 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3993 Added silc_client_rekey_callback and silc_client_rekey_final.
3994 Affected files are lib/silcclient/protocol.[ch] and
3995 lib/silcclient/client.[ch].
3997 * Removed the `hmac_key' and `hmac_key_len' fields from the
3998 SilcClientConnection structure; not needed. Affected file is
3999 lib/silcclient/client.h.
4003 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Do not ask whether user wants to use the negotiated private key
4006 for private messages, just use it. Affected file is
4007 silc/local_command.c.
4009 * Added `send_enc_key' and `enc_key_len' fields to the
4010 SilcIDListData structure since they are needed in the re-key
4011 phase. Affected file is silcd/idlist.[ch].
4013 * Implemented the simple re-key protocol into the server.
4014 Affected files silcd/server.c and silcd/protocol.[ch]. The
4015 re-key will be performed once in an hour, by default.
4017 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4018 Added silc_server_rekey, silc_server_rekey_callback and
4019 silc_server_rekey_final.
4021 * Removed Tunneled flag from the protocol. Updated the code
4022 and the specifications.
4024 * Adde `pfs' field to the SilcIDListData to indicate whether
4025 the PFS is to be performed in the re-key. Affected file is
4028 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4031 int64 of at least the xintXX size. If void * is less that 4
4032 bytes uint32 * will be used. Defined bool as boolean.
4034 * Changed _ALL_ unsigned long and unsigned int to uint32,
4035 unsgined short to uint16 in the source tree.
4037 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4038 not handle clients that has entry->data.registered == FALSE.
4039 They are not in the network anymore. Affected file is
4042 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Implemented the sending of the SERVER_SIGNOFF notify in the
4045 server. Affected file is silcd/server.c.
4047 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4048 Added also silc_notify_payload_encode_args into the
4049 lib/silccore/silcnotify.[ch].
4051 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4052 Affected file silcd/packet_receive.c.
4054 * Implemented the SERVER_SIGNOFF notify handling in the client
4055 library. Affected file lib/silcclient/client_notify.c. Also,
4056 implemnted the printing of the SERVER_SIGNOFF info to the
4057 application. Affected file silc/client_ops.c.
4059 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4060 if the deleting was successful. Affected file silcd/idlist.[ch].
4062 * Added support for public key authentication in the connection
4063 authentication protocol in the client library. Affected file
4064 lib/silcclient/protocol.c.
4066 * Changed the server's silc_idlist_get_clients_by_* interface
4067 to support already allocated array so that new entries may be
4068 added to pre-allocated array. Affected file silcd/idlist.[ch].
4069 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4070 and command replies.
4072 * All command reply functions in the server now calls the
4073 pending command callback even if error occured. This way the
4074 error will be delivered to the client as well. Affected files
4075 silcd/command.c and silcd/command_reply.c.
4077 * Fixed INFO command to return local server's info if no server
4078 was provided. Affected file lib/silcclient/command.c.
4080 * Removed RESTART command for good. Updated the code and the
4083 * Rewrote parts of the task system. It is a bit simpler now.
4084 Removed unsued task priorities. The affected files are
4085 lib/silcutil/silctask.[ch].
4087 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Moved the USERS printing from the library to the application.
4090 Affected files lib/silcclient/command.c and silc/client_ops.c.
4092 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Added channel key re-key support. The re-key is perfomed
4097 only by the router and is done once in an hour. Added `rekey'
4098 field to the SilcChannelEntry in the server. Affected files
4099 silcd/server.c and silcd/idlist.h.
4101 * Added silc_task_unregister_by_context into the file
4102 lib/silcutil/silctask.[ch].
4104 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Added SILC_UMODE_GONE mode to indicate when the client is not
4107 present in the SILC network. Added also support to the local
4108 command AWAY that will set this mode. Added support of showing
4109 "xxx is gone" in WHOIS command. The USERS command shows the
4110 gone status as well.
4112 * Fixed setting server and router operator privileges in the
4113 server's UMODE command. Affected file silcd/command.c.
4115 * Merged the SKE KE1 and KE2 payloads into one payload. The
4116 new KE payload is equivalent to the old KE2 payload.
4118 Cleaned up the SKE Start Payload parsing. It now uses the
4119 simple buffer unformatting to do the parsing. A lot faster
4122 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4123 to the SKE that is used to indicate whether both of the SKE
4124 parties should perform authentication. By default only the
4125 responder performs authentication. By setting this flag also
4126 the initiator must do authentication. By default it is unset
4127 since in normal SKE case, client to server connection, only
4128 the responder should do authentication. When doing SKE between
4129 two clients both should perform authentication. Updated the
4130 code and the protocol specs.
4132 * A little fix to IDENTIFY command in the server. Search the
4133 client first by hash not nickname. Affected file is
4136 * Fixed the silc_client_close_connection to support closing
4137 the client to client connections wihtout deleting too much
4138 data. Affected file lib/silcclient/client.c.
4140 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4141 are received if protocol used to be active but is not anymore
4142 the application would crash due to NULL pointer dereference.
4143 Affected files silcd/server.c and lib/silcclient/client.c.
4145 * Added `hash' field to the SilcClientConnection to include
4146 the hash function negotiated in the SKE protocol.
4148 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4149 to set the channel founder authentication data. A client can
4150 claim the founder rights later by providing the authentication
4151 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4152 This way the channel founder can regain the channel founder
4153 privileges even it is left the channel. This works only on
4154 local server and the client must be connected to the same
4155 server to be able to regain the founder rights. Updated the
4156 protocol specs accordingly.
4158 Added support to the CMODE command in the client to set the
4159 founder auth data. Read the README to see how to set it.
4161 Added support to the CUMODE command to claim the founder
4162 rights. Read the README to see how to do it.
4164 Added support for the founder authentication to the Channel
4165 Entry in the server. Affected file silcd/idlist.h.
4167 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4168 server's CMODE command. Affected file silcd/command.c.
4170 * Added the following new functions into lib/silccore/silcauth.[ch]:
4171 silc_auth_get_method and silc_auth_get_data.
4173 * The server now saves the remote hosts public key to the
4174 SilcIDListData pointer. Affected file silcd/protocol.c.
4176 * The normal server now does not remove the channel entry from
4177 the cache if the founder authentication data is set. It used
4178 to remove it if the founder was the last one on the channel on
4179 the server and left the channel. The auth data is saved and
4180 if the channel is re-joined later the old entry is used with
4181 the old auth data. Affected files silcd/command_reply.c and
4184 * Removed the `pkcs' field from the SilcIDListData structure
4185 in the server; it is not used. Affected file silcd/idlist.h.
4187 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed packet processing on slow links. Partial packets were
4190 never re-processed because the incoming data buffer was cleared
4191 by the application. Application must not directly clear the
4192 sock->inbuf, the packet processing routines handle it. Fixed
4193 this in client library and in server.
4195 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Fixed the WHOIS and IDENTIFY send reply function to really
4198 check whether to send list or just one entry. Affected file
4201 * Cleaned up the LEAVE command's channel key distribution. The
4202 affected file silcd/command.c.
4204 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4205 can enforce the channel mode as well. In that case the ID
4206 includes the ID of the server. The code now enforces the
4207 mode change if the router have different mode than the server.
4209 * The notify client operation with CMODE_CHANGE notify can now
4210 return NULL client_entry pointer if the CMODE was not changed
4211 by client. Application must check for this.
4213 * Added <Server ID> argument to INFO command to support server
4214 info fetching by Server ID.
4216 * Added silc_server_announce_get_channel_users to get assembled
4217 packets of channel users of the specified channel. Affected
4218 file silcd/server.[ch].
4220 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4221 was freed underneath the ID Cache.
4223 * Re-announce clients when the server received CHANNEL_CHANGE
4224 notify from the router. Affected file silcd/packet_send.c.
4226 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4229 crashed since it did not handle the fact that there is no cipher
4230 called "3" and didn't check the error condition. Now fixed.
4232 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4233 flag. It can be used to send message requests.
4235 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Implemented the RESTART command in the client.
4239 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4240 notice type messages. Added notice printing to the user
4243 * The channel keys are not re-generated if the channel's mode
4244 is PRIVKEY, ie private key on the channel exists. Affected
4245 files silcd/server.c and silcd/command.c.
4247 * Fixed a little bug in channel message delivery when channel
4248 private keys are set in the server. Affected file is
4249 silcd/packet_send.c.
4251 * Changed the setting on channel->on_channel = TRUE from the
4252 silc_client_save_channel_key to the JOIN command reply. The
4253 key payload is not received if the private channel key is set.
4254 Affected file lib/silcclient/command_reply.c and the
4255 lib/silcclient/client_channel.c.
4257 * When the CMODE_CHANGE notify is sent and the channel private
4258 key mode is removed the channel key must be re-generated in
4259 other cells as well. Added this support for the router in the
4260 silcd/packet_receive.c.
4262 * Added new local command NOTICE to send notice message on
4263 channel. Affected file silc/local_command.[ch].
4265 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added new local command ME to the client. It is used to send
4268 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4269 some action. Affected file silc/local_command.[ch].
4271 * Changed channel_message and private_message client operations
4272 to deliver the message flags to the application. Added also
4273 the `flags' arguments to the silc_client_send_channel_message
4274 and silc_client_send_private_message functions. Affected file
4277 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Redefined the Private Message Payload to support private message
4280 keys and to support the new private message flags. Updated
4281 the protocol specs. Flags makes it possible to have for example
4282 CTCP style messages.
4284 * Added new type SilcPrivateMessagePayload and defined an API
4285 for it in the lib/silcclient/silcprivate.[ch].
4287 * Tested private message private keys successfully. Tested the
4288 private message key set, unset and list commands with the new
4291 * Redefined the Channel Message Payload to include the channel
4292 message flags (equal with private message flags) to support
4293 for example CTCP style messages.
4295 * Defined some of the message (for channel and private message)
4296 flags. Updated the protocol specs and added the flags to the
4297 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4299 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added SilcKeyAgreementStatus type to the key agreement routines
4302 to indicate the current status and error if one occured.
4303 The status types are defined in the lib/silcclient/silcapi.h.
4305 * Added new local command KEY that is used to set and unset private
4306 keys for channels, set and unset private keys for private messages
4307 with remote clients and to send key agreement requests and
4308 negotiate the key agreement protocol with remote client. The
4309 key agreement is supported only to negotiate private message keys,
4310 it currently cannot be used to negotiate private keys for channels,
4311 as it is not convenient for that purpose.
4313 * Fixed a minor pending callback setting bug in the function
4314 silc_client_get_client_by_id_resolve, now the function works.
4315 Affected file lib/silcclient/idlist.c.
4317 * Added function silc_net_get_local_port to get local bound
4318 port by socket. Added to lib/silcutil/silcnet.[ch].
4320 * Added `sockets' and `sockets_count' fields to the SilcClient
4321 object. They hold the sockets of the listenning sockets in
4322 the client. Listenning sockets may be for example the key
4323 agreement server. Affected file lib/silcclient/client.[ch].
4324 Added functions the silc_client_add_socket and the
4325 silc_client_del_socket. They are exported to the application
4328 * Added ~./silc/clientkeys to support other client's public keys.
4330 * Renamed verify_server_key client operation to verify_public_key
4331 and added one argument to indicate the type of the connection
4332 (server, client etc.).
4334 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Added silc_server_connection_auth_request to handle the
4337 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4338 silcd/packet_receive.[ch].
4340 * Added silc_server_send_connection_auth_request into the
4341 silcd/packet_send.c to send the connection auth request packet.
4343 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4346 * Fixed the public key authentication in responder side in the
4347 server. The `auth_data' pointer includes the SilcPublicKey
4348 not the path to the public key. Affected file silcd/protocol.c.
4350 * Implemented the public key authentication in the initiator side
4351 in the server. Affected file silcd/protocol.c.
4353 * Removed the [RedirectClient] config section from the server
4354 configuration. Is not needed and I don't want to implement it.
4356 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Cleaned up the CMODE command in the server. It now works
4359 correctly and supports all the modes defined in the protocol.
4360 Affected file is silcd/command.c.
4362 * Added `hmac_name' field to the SilcChannelEntry in the server
4363 to hold the default HMAC of the channel. It can be set when
4364 creating the channel (with JOIN command). Affected files
4367 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4368 type to indicate the change of the current cipher and hmac
4369 on the channel. Client can safely ignore the <cipher> argument
4370 (if it chooses to do so) since the CHANNEL_KEY packet will
4371 force the channel key change anyway. The <hmac> argument is
4372 important since the client is responsible of setting the new
4373 HMAC and the hmac key into use.
4375 * Fixed the CMODE command in the client library as well.
4377 * Tested CMODE command in router environment successfully.
4379 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Show the version of the remote client (or server) when connecting
4382 to the server. It is logged to the log file. Affected file
4383 is silcd/protocol.c.
4385 * Fixed the KILLED notify handling in the client library. The
4386 client must be removed from all channels when receiving the
4389 Also, do not remove the client entry when giving the KILL
4390 command but when the KILLED notify is received.
4392 * Removed silc_idlist_find_client_by_nickname from the server.
4393 Not needed anymore. Affected files silcd/idlist.[ch].
4395 * Implemented the CHANNEL_CHANGE notify type handling to the
4396 server. Affected file silcd/server.c.
4400 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added silc_server_send_notify_invite to send the INVITE
4403 notify between routers.
4405 * Implemented the INVITE command correctly to the server.
4407 * Implemented the INVITE notify type handling in the server.
4409 * Implemented the INVITE command to the client library and on the
4412 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added function silc_server_get_client_resolve to find the
4415 client entry by ID from all ID lists and then resolve it
4416 (using WHOIS) if it cannot be found. Affected file is
4419 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Implemented the BAN command to the client library.
4423 * The JOIN command in the server now checks the invite list
4426 * Changed the silc_command_reply_payload_encode_va and the
4427 silc_command_payload_encode_va to support that if argument is
4428 NULL it ignores and checks the next argument. Affected file
4429 lib/silccore/silccommand.c.
4431 * Added silc_server_send_notify_ban to send the BAN notify
4432 type between routers.
4434 * Chaned the silc_notify_payload_encode to support that if
4435 argument is NULL it ignores and checks the next argument.
4436 Affected file lib/silccore/silcnotify.c.
4438 * Tested ban lists in router environment successfully.
4440 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Implemented BAN command to the server, in silcd/command.[ch].
4444 * Removed the BAN and INVITE_LIST modes from the CMODE command
4447 * Added function silc_string_match to regex match two strings.
4448 Affected files lib/silcutil/silcutil.[ch].
4450 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Redefined parts of the SilcChannelEntry in the server to support
4453 the new ban and invite lists.
4455 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Redefined the INVITE command. The same command can be used to
4458 invite individuals to the channel but also to manage the invite
4459 list of the channel (to add to and remove from the invite list).
4460 Updated the protocol specs.
4462 * Added new command SILC_COMMAND_BAN that can be used to manage
4463 the ban list of the channel. Updated the protocol specs.
4465 * Removed the channel modes: the SILC_CMODE_BAN and the
4466 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4467 in the CMODE command. The equivalent features are now available
4468 using INVITE and BAN commands. Updated the protocol specs.
4470 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4471 in the network about change in the current ban list. The notify
4472 type is not used by the client.
4474 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4475 support the invite lists.
4477 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added new function silc_string_regexify that converts string
4480 including wildcard characters into regex string that can
4481 be used by the GNU regex library. Added into the file
4482 lib/silcutil/silcutil.[ch].
4484 Added silc_string_regex_combine to combine to regex strings
4485 into one so that they can be used as one regex string by
4486 the GNU regex library. Added into the file
4487 lib/silcutil/silcutil.[ch].
4489 Added silc_string_regex_match to match two strings. It returns
4490 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4492 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Imported GNU regex to the soruce tree into lib/contrib.
4495 Fixed some compiler warning from the regex.c.
4497 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Fixed MOTD command in the server to work in router environment.
4501 * Fixed the MOTD command in the client library to support
4502 the server argument in the command.
4504 * Added `nickname_len' argument to the silc_idlist_add_client
4505 in the server, as the `nickname' argument may be binary data
4508 * Added silc_idlist_get_channels to return all channels from
4511 * Implemented LIST command to the server. Affected file is
4514 * Implemented the LIST command to the client library and on the
4517 * Added [<user count>] argument to the LIST command reply.
4518 With private channels the user count is not shown.
4520 * Updated TODO and README.
4522 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * The client entry's data.registered must be TRUE even with
4525 global client entry on global client list. The data.registered
4526 is used to check whether the client is anymore in the network,
4527 for example with WHOWAS command so it must be valid.
4529 * Fixed the WHOWAS command in the server. It now actually works
4530 in router environment. Added function into silcd/command_reply.c
4531 silc_server_command_reply_whowas_save.
4533 * Added silc_idlist_purge function to the silcd/idlist.c
4534 to periodically purge the ID Cache.
4536 * Fixed INFO command in the server. It works now in router
4537 environment. Added <server name> argument to the INFO command
4538 reply. Updated the protocol specs.
4540 * Fixed minor bug in silc_idcache_purge to not purge if the
4541 expire value is zero.
4543 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4544 they were buggy because of the WHOWAS information.
4546 * Fixed local command MSG to handle the async resolving of
4547 the remote client properly. It used to fail the first MSG.
4548 Affected file silc/local_command.c.
4550 * Added `data_len' field to SilcIDCache context.
4552 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Update TODO. Todo in commands in the server.
4556 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4559 used by routers as broadcast packet to inform other routers
4560 about the changed user mode.
4562 Implemented the notify handling in the server. Affected file is
4563 silcd/packet_receive.c. Added the function
4564 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4566 * Added new generic Channel Payload and deprecated the New Channel
4567 Payload. The New Channel Payload is now the generic Channel
4570 * Added new argument `mode' to the silc_server_send_new_channel
4571 as it is required in the Channel Payload now.
4573 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4574 and created a new and real SilChannelPayload to represent the
4575 new generic Channel Payload. Implemented the encode/decode
4576 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4578 * Added silc_server_get_client_channel_list to return the list
4579 of channels the client has joined for WHOIS command reply.
4580 Affected file silcd/server.[ch].
4582 * Implemented the channel list sending in the WHOIS command reply
4583 in server and in the client.
4585 Implemented the channel list displaying on the user interface
4586 as well. Affected file silc/client_ops.c.
4588 * Added silc_channel_payload_parse_list to parse list of Channel
4589 Payloads. It returns SilcDList list of SilcChannelPayloads.
4590 Client for example can use this function to parse the list of
4591 channels it receives in the WHOIS command reply. The caller
4592 must free the list by calling silc_channel_payload_list_free.
4593 Affected files lib/silccore/silcchannel.[ch].
4595 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added one new argument <user mode> to the WHOIS command reply
4598 to return the mode of the user in SILC. Updated the protocol
4601 Implemented it to the server and client.
4603 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Fixed the mode printing on the user interface on joining.
4606 Affected file silc/client_ops.c.
4608 * Implemented the UMODE command and user modes in general to the
4609 client library and to the user interface.
4611 * Implemented the UMODE command to the server.
4613 * The server now sends UNKNOWN_COMMAND error status if client sends
4614 unknown command. Affected file silcd/command.c.
4616 * All server commands now handle the command identifier the right
4617 way when sending the command reply to the client. The client can
4618 use to identify the command replies with the identifier.
4620 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added silc_server_get_client_route to resolve the route to
4623 the client indicated by the client ID. Affected file is
4626 * Added silc_server_relay_packet as general function to relay
4627 packet to arbitrary destination. This deprecates functions
4628 like _send_private_message_key, _relay_notify etc. Affected
4629 file is silcd/packet_send.[ch].
4631 Removed silc_server_send_key_agreement,
4632 silc_server_send_private_message_key and
4633 silc_server_packet_relay_notify functions from the file
4634 silcd/packet_send.[ch].
4638 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4639 server. Affected file silcd/packet_receive.[ch].
4641 * Implemented the KILL command to the client. Implemented the
4642 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4643 Affected files lib/silcclient/command[_reply].c and
4644 lib/silcclient/client_notify.c. Implemented the KILL notify
4645 printing in the user inteface.
4647 * Fixed a lot silc_parse_nick memory leaks from the client
4648 library in the file lib/silcclient/command.c.
4650 * Changed the silc_server_send_notify_on_channels's `sender'
4651 argument from SilcSocketConnection to SilcClientEntry to
4652 check the sender as entry and not as connection object and not
4653 to send to the client provided as argument. The affected file
4654 is silcd/packet_send.[ch].
4656 * The notify packets that are destined directly to the client used
4657 to not to be processed by the server. Now changed that and the
4658 server processes all notify packets. After relaying the packet
4659 to the client the notify packet is processed in the server.
4661 * The silc_server_free_client_data now checks whether there is
4662 pending outgoing traffic for the client and purges the data to
4663 the network before removing the client entry.
4665 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4668 an client is killed from the SILC Network. Updated the protocol
4671 Added new function silc_server_send_notify_killed to the
4672 silcd/packet_send.[ch].
4674 * Added function silc_server_packet_relay_notify to relay notify
4675 packets that are destined directly to a client. In this case
4676 the server does not process the notify packets but merely relays
4677 it to the client. Affected file silcd/packet_send.[ch].
4679 Added also silc_server_packet_process_relay_notify to check
4680 whereto relay the notify. Affected file is
4681 silcd/packet_receive.[ch].
4683 * Implemented the KILL command to the server.
4687 * Added the backup schema desgined last fall to the protocol
4688 specs for everyone to see. The specification is in the
4689 *-spec-xx.txt draft and the packet type definitions for the
4690 backup routers is in *-pp-xx.txt draft. Thusly, added also
4691 new packet type SILC_PACKET_CELL_ROUTERS.
4693 * A big security problem in the implementation discovered. The
4694 signoff of an client did not cause new channel key generation
4695 which it of course should've done. The channel keys must be
4696 always re-generated when client leaves (or signoffs) the channel.
4697 The silc_server_remove_from_channels funtion now handles
4698 the channel key re-generation.
4700 * Added `sender' argument to the silc_server_send_notify_on_channels
4701 to not to send the client provided as argument. Affected file
4702 silcd/packet_send.[ch].
4704 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Implemented OPER and SILCOPER commands into the server and
4709 * Added silc_auth_verify and silc_auth_verify_data to verify
4710 the authentication directly from the authentication payload.
4711 It supports verifying both passphrase and public key based
4712 authentication. Affected file lib/silccore/silcauth.[ch].
4714 * Added `hash' field to the SilcIDListData structure. It is the
4715 hash negotiated in the SKE protocol. Affected file is
4718 * Slight redesigning of the SilcAuthPayload handling routines.
4719 Do not send SilcPKCS but SilcPublicKey as argument.
4721 * Implemented the public key authentication support to the
4722 serverconfig. The public key is loaded from the provided path
4723 and saved as authentication data to void * pointer. Thus,
4724 changed the unsigned char *auth_data to void *auth_data;
4726 * Fixed SHUTDOWN command to send the reply before the server
4727 is shutdown. :) Affected file silcd/command.c.
4729 * Fixed fatal bug in CONNECT command. The hostname was invalid
4730 memory and server crashed. Affected file silcd/command.c.
4732 * Fixed fatal bug in CLOSE command. The server_entry became
4733 invalid but was referenced later in the command. Affected file
4736 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Fixed fatal bug in failure packet handling. Server ignored
4739 the failure and thus crashed when it came.
4743 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4746 that the command may be executed only once in (about) 2 seconds.
4747 The old SILC_CF_LAG flag is same but allows command bursts up
4748 to five before limiting.
4750 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4751 server code. Various commands now includes the CF_LAG_STRICT
4752 flag to disallow any kind of miss-use of the command.
4754 * Fixed the silc_buffer_unformat to not to allocate any data
4755 if the length of the data is zero. It used to allocate the
4756 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4758 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Changed the format of AdminConnection configuration section
4761 in the server. Added username of the admin to the format.
4762 Affected files silcd/serverconfig.[ch].
4764 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4765 to return admin configuration data by host, username and/or
4768 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Implemented WHOWAS command to the server. Added the functions:
4772 silc_server_command_whowas_parse,
4773 silc_server_command_whowas_send_reply,
4774 silc_server_command_whowas_from_client and
4775 silc_server_command_whowas_from_server
4777 * Added <Client ID> argument to the WHOWAS command reply. Updated
4778 the protocol specs accordingly.
4780 * Implemented WHOWAS command and command_reply to the client
4783 Implemented the WHOWAS printing on the user interface.
4785 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added new argument to the WHOWAS command reply, the real name.
4788 It is an optional argument. Updated the protocol specs.
4790 * Added SilcIDCacheDestructor callback that is registered when
4791 the SilcIDCache is allocated. The callback is called when
4792 an cache entry in the ID Cache expires, or is purged from the
4793 cache. Added into lib/silccore/idcache.[ch].
4795 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4796 to destruct the client entries when the cache entry expires.
4797 Other ID Cache's in server and in the client library ignores
4800 * If the ID Cache entry's `expire' field is zero then the entry
4801 never expires. Added boolean `expire' argument to the
4802 silc_idcache_add function in the lib/silccore/idcache.[ch].
4803 If it is TRUE the default expiry value is used.
4805 * Added silc_server_free_client_data_timeout that is registered
4806 when client disconnects. By default for 5 minutes we preserve
4807 the client entry for history - for WHOWAS command.
4809 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added support to the server to enforce that commands are not
4812 executed more than once in 2 seconds. If server receives
4813 commands from client more frequently, timeout is registered
4814 to process the commands. Affected file silcd/command.c.
4815 Added new function silc_server_command_process_timeout.
4817 * Changed NICK_NOTIFY handling in client library to check that
4818 if the client's nickname was changed, so there is no need to
4819 resolve anything from the server.
4821 * Removed error printing from the WHOIS and IDENTIFY commands.
4822 If error occurs then it is ignored silently in the client library.
4823 The application, however, may map the received error to
4824 human readable error string. The application currently maps
4825 the NO_SUCH_NICKNAME error to string.
4827 * Made the command status message public to the application. Moved
4828 them from lib/silcclient/command_reply.c to
4829 lib/silcclient/command_reply.h. The application can map the
4830 received command status to the string with the
4831 silc_client_command_status_message function.
4833 * Added check to the server to check that client's ID is same
4834 as the Source ID in the packet the client sent. They must
4837 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Added dist-bzip hook to the Makefile.am to make bzip2
4840 compressed distributions.
4842 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Server now enforces the maximum length for the nickname and
4845 the channel as protocol specification dictates. 128 bytes for
4846 nickname and 256 bytes for channel name.
4848 * Moved the WHOIS printing to the application. The client libary
4849 does not print out the WHOIS information anymore, the application
4850 must do it. Renamed silc_client_command_reply_whois_print to
4851 the silc_client_command_reply_whois_save.
4853 The client's idle time is also sent to the application now, and
4854 the idle is shown on screen.
4856 * Added silc_client_command_reply_identify_save to save the
4857 received IDENTIFY entries.
4859 * Do not check for channel private keys in message sending and
4860 reception if the channel does not have the PRIVKEY mode set.
4861 Affected file lib/silclient/client_channel.c.
4863 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4866 just surfaced after chaning the JOIN procedure.
4868 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added silc_client_get_clients_by_list to get client entries
4871 from Client ID list, that is returned for example by JOIN
4872 and USERS command replies. The application should use this
4873 function for example when JOIN command reply is received to
4874 resolve the clients already on the channel (library does not
4875 do that anymore as USERS command reply is not used in the JOIN
4876 procedure anymore). Affected files lib/silcclient/silcapi.h and
4877 lib/silcclient/idlist.c.
4879 * JOIN command reply and USERS command reply returns now SilcBuffer
4880 pointers instead of unsigned char pointers when returning
4881 the client list and mode list.
4883 * Added <Client ID> argument to the JOIN command reply, mainly
4884 for the server to identify for which client the command was
4885 originally sent. Updated protocol specs accordingly.
4887 * Added SilcDlist private_key pointer to the SilcChannelEntry
4888 in the client to support the channel private keys. Affected
4889 file is lib/silcclient/idlist.h.
4891 * Added SilcChannelPrivateKey argument to the function
4892 silc_client_send_channel_message so that application can choose
4893 to use specific private ke if it wants to. If it is not provided,
4894 the normal channel key is used, unless private keys are set.
4895 In this case the first (key that was added first) is used
4896 as the encryption key.
4898 * Implemented the support for channel private key handling.
4899 Implemented the following functions:
4901 silc_client_add_channel_private_key,
4902 silc_client_del_channel_private_keys,
4903 silc_client_del_channel_private_key,
4904 silc_client_list_channel_private_keys and
4905 silc_client_free_channel_private_keys
4907 Affected file lib/silcclient/client_channel.c.
4909 * Added the support for the private keys in the channel message
4910 sending and encryption and in the message reception and
4911 decryption. Affected funtions are
4912 silc_client_send_channel_message and silc_client_channel_message.
4914 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added SKE's key verify callback to the client library's
4917 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4919 * Removed the statement that server (or router) must send USERS
4920 command reply when joining to the channel so that the client
4921 knows who are on the channel. Instead, the client list and
4922 client's mode list is now sent in the JOIN command reply to the
4923 client who joined channel. This is better solution.
4925 * Added function silc_server_get_users_on_channel and function
4926 silc_server_save_users_on_channel to the silcd/server.[ch].
4928 * Removed function silc_server_command_send_users from the
4931 * Do not show topic on the client library anymore. The topic is
4932 sent in the command reply notify to the application and the
4933 application must show the topic now.
4935 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Added client searching by nickname hash into the IDENTIFY and
4938 WHOIS commands in the server as they were clearly missing from
4939 them. Affected file is silcd/command.c.
4941 * Fixed a bug in private message receiving in the client library.
4942 The remote ID was freed and it wasn't supposed, now it is
4945 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Minor fix to the channel payload; allocate the data area, as it
4948 needs to be of specific length.
4950 * If the key agreement port is zero then the operating
4951 system will define the bound port. Affected files are
4952 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4954 * Added new function silc_channel_payload_decrypt into the file
4955 lib/silccore/silcchannel.[ch].
4957 * Moved the channel message etc, check from silc_packet_decrypt
4958 to applications. The library calls now a generic
4959 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4960 when the packet is either normal or special. This was done to
4961 allow more wide range of checking that was not allowed when
4962 the code was in library. Now applications can do virtually any
4963 checks to the packet and return to the library the decision how
4964 the packet should be processed. Affected files are
4965 lib/silccore/silcpacket.[ch].
4967 Added silc_server_packet_decrypt_check to the server and
4968 silc_client_packet_decrypt_check to the client library.
4970 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4971 to send with specified source and destination information.
4973 * Channel message delivery between routers was broken after the
4974 channel key distribution was fixed earlier. The channel key
4975 was used be to distributed to other routers as well which is not
4976 allowed by the protocol. Now this is fixed and channel keys
4977 really are cell specific and the channel message delivery between
4978 routers comply with the protocol specification.
4980 * Fixed various commands in server to check also the global list
4981 for the channel entry and not just the local list. The affected
4982 file silcd/command.c.
4984 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added assert()s to buffer formatting and unformatting routines
4987 to assert (if --enable-debug) when error occurs. Affected
4988 file: lib/silcutil/silcbuffmt.c.
4990 * Changed to auto-reconnect to check whether the remote host is
4991 router and register the re-connect timeout if it is. It used
4992 to check that whether we are normal server, but router must do
4993 auto-reconnect with another router as well. Affected file
4996 * Removed the [<key len>] option from CMODE command as the cipher
4997 name decides the key length, nowadays. See the defined ciphers
4998 from the protocol specification.
5000 * Added [<hmac>] option to the CMODE command to define the HMAC
5001 for the channel. Added SILC_CMODE_HMAC channel mode.
5003 * Added [<hmac>] option for the JOIN command so that user can
5004 select which HMAC is used to compute the MACs of the channel
5007 * Added Hmac field to the Channel Message Payload. The integrity
5008 of plaintext channel messages are now protected by computing
5009 MAC of the message and attaching the MAC to the payload. The
5010 MAC is encrypted. Now, it is clear that this causes some
5011 overhead to the size of the packet but rationale for this is that
5012 now the receiver can verify whether the channel message decrypted
5013 correctly and also when private keys are set for the channel the
5014 receiver can decrypt the packet with several keys and check from
5015 the MAC which key decrypted the message correctly.
5017 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5018 lib/silccrypt/silccipher.[ch].
5020 * Added silc_hash_len to return the digest length into the
5021 lib/silcrypt/silchash.[ch].
5023 * Rewrote parts of Silc Channel Payload interface in the
5024 lib/silccore/silcchannel.[ch]. The encode function now also
5025 encrypts the packet and parse function decrypts it.
5027 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Fixed a minor formatting bug in the SKE's key material processing.
5030 It actually might have processed the keys wrong way resulting
5033 * Redefined the mandatory HMAC algorithms and added new algorithms.
5034 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5035 and hmac-md5 truncated to 96 bits. The mandatory is now
5036 hmac-sha1-96. Rest are optional (including the one that used
5037 to be mandatory). Rationale for this is that the truncated HMAC
5038 length is sufficient from security point of view and can actually
5039 make the attack against the HMAC harder. Also, the truncated
5040 HMAC causes less overhead to the packets. See the RFC2104 for
5043 * Added new [hmac] configuration section. The SKE used to use
5044 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5045 is of course wrong. The official names that must be proposed in
5046 the SKE are the ones defined in the protocol specification
5047 (hmac-sha1-96 for example). The user can configure any hmac
5048 using any hash function configured in the [hash] section. At
5049 least, the mandatory must be configured.
5051 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5053 * Added HMAC list to the SKE proposal list. It has now both
5054 hash algorithm list and HMAC list. This makes the protocol
5055 incompatible with previous versions. The SKE now seems to work
5056 the way it is supposed to work, for the first time actually.
5058 * Defined plain Hash algorithms to the protocol specification.
5061 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Implemented support for key agreement packets into the server.
5064 Added functions silc_server_key_agreement and
5065 silc_server_send_key_agreement. Other than these functions,
5066 server has nothing to do with this packet.
5068 * Added support for private message key packets into the server.
5069 Added functions silc_server_private_message_key and
5070 silc_server_send_private_message_key.
5074 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5075 called in the protocol's final callback instead in the END
5076 protocol state. This makes a little more sense and in the same
5077 time in client we can use the same protocol routines for normal
5078 key exchange and to key agreement packet handling as well.
5080 * Added to both client's and server's KE protocol context the
5081 SilcSKEKeyMaterial pointer to save the key material. We will
5082 bring the key material to the protocol's final callback by doing
5083 this. The final callback must free the key material.
5085 * Added SKE's packet_send callback into client's KE protocol
5086 context so that the caller can choose what packet sending function
5087 is used. This way we can use different packet sending when
5088 doing normal SKE when doing key agreement packet handling (in
5089 the key agreement packet handling we do not want to encrypt
5092 * Implemented the responder side of the key agreement routines
5093 in the client. The client can now bind to specified port and
5094 accept incoming key negotiation. The key material is passed
5095 to the application after the protocol is over.
5097 * Implemented the processing of incoming Key Agreement packet
5098 in the client. Added function silc_client_key_agreement to
5101 * Implemented the intiator side of the key agreement routines
5102 in the client. The client can now initiate key agreement with
5103 another remote client. The key material is passed to the
5104 application after the protocol is over.
5106 * Created client_keyagr.c to include all the key agreement
5109 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5110 SILC_TASK_CALLBACK except that it is not static.
5112 * Created client_notify.c and moved the Notify packet handling
5113 from the client.[ch] into that file.
5115 * Created client_prvmsg.c and moved all private message and
5116 private message key routines from the client.[ch] into that file.
5118 * Create client_channel.c and moved all channel message and
5119 channel private key routines from the client.[ch] into that file.
5121 * Changed silc_client_get_client_by_id_resolve to resolve with
5122 WHOIS command instead of IDENTIFY command, in the file
5123 lib/silclient/idlist.c.
5125 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Implemented the SKE's responder side to the Client library.
5129 * When FAILURE is received to the protocol do not trust it
5130 blindly. Register a timeout to wait whether the remote closes
5131 the connection as it should do it, only after that process the
5132 actual failure. This was changed to both client and server.
5134 * Added client_internal.h to include some of the structures
5135 there instead of client.h in lib/silcclient/.
5137 * Added function silc_task_unregister_by_callback to unregister
5138 timeouts by the callback function.
5140 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Some "Incomplete WHOIS info" errors has been appearing on the
5143 log files. Took away the entry->userinfo check from WHOIS
5144 reply sending. The entry->userinfo is now " " if client did not
5145 provide one. I thought this was fixed earlier but something
5146 is wrong still. Let's see if the error still appears.
5148 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Fixed a minor bug in the login when the channel key is
5151 re-generated in the server. It used to generate the key in
5152 wrong order and thus caused problems in the channel traffic.
5154 * Fixed a minor bug in channel key distsribution after
5155 KICK command. The key was not sent to the router even though
5158 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added silc_ske_process_key_material_data as generic routine
5161 to process any key material as the SILC protocol dictates. The
5162 function is used by the actual SKE library but can be used by
5163 applications as well. This relates to the private message keys
5164 and the channel private keys since they must be processed the
5165 same way the normal SILC session keys. The protocol dictates
5166 this. Affected files: lib/silcske/silcske.[ch].
5168 Added also silc_ske_free_key_material to free the
5169 SilcSKEKeyMaterial structure.
5171 * Defined silc_cipher_set_key function to set the key for
5172 cipher without using the object's method function. The affected
5173 files: lib/silccrypt/silccipher.[ch].
5175 * Implemented silc silc_client_add_private_message_key,
5176 silc_client_add_private_message_key_ske,
5177 silc_client_del_private_message_key,
5178 silc_client_list_private_message_keys and
5179 silc_client_free_private_message_keys functions in the
5182 Added functions silc_client_send_private_message_key to send
5183 the Private Message Key payload and silc_client_private_message_key
5184 to handle incoming Private Message Key payload.
5186 * Added Cipher field to the Private Message Key payload to set
5187 the cipher to be used. If ignored, the default cipher defined
5188 in the SILC protocol (aes-256-cbc) is used.
5190 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Removed lib/silcclient/ops.h file.
5194 Redefined parts of the SILC Client Library API. Created new
5195 file silcapi.h that deprecates the ops.h file and defines the
5196 published Client Library API. Defined also private message key
5197 API and channel private key API into the file.
5199 This is the file that the application must include from the
5200 SILC Client Library. Other files need not be included by
5201 the application anymore.
5203 * Added new key_agreement client operation callback and also
5204 defined the Key Agreement library API for the application.
5206 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5209 is used by clients to request key negotiation between another
5210 client in the SILC network. If the negotiation is started it
5211 is performed using the SKE protocol. The result of the
5212 negotiation, the secret key material, can be used for example
5213 as private message key.
5215 Implemented the Key Agreement payload into the files
5216 lib/silccore/silauth.[ch].
5218 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Redefined ciphers for the SILC protocol. Added some new ciphers
5221 and defined the key lengths for the algorithms. Changed the
5222 code accordingly. The default key length is now 256 bits.
5224 * Fixed SKE key distribution function silc_ske_process_key_material
5225 when the key length is more than 128 bits. The default key
5226 length in SILC is now 256 bits.
5228 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5229 to indicate unsupported algorithm.
5231 * Renamed rijndael.c to aes.c and all functions as well.
5233 * Fixed a long standing channel key setting bug in client library.
5234 Weird that it has never surfaced before.
5236 * Fixed bug in channel deletion. If the entire channel is removed
5237 then it must also delete the references of the channel entry
5238 from the client's channel list as the client's channel entry and
5239 the channel's client entry share same memory.
5241 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Implemented CONNECT and SHUTDOWN commands in the client.
5245 * Implemented CLOSE command to the client.
5247 * Added the function silc_idlist_find_server_by_name into the
5248 files silcd/idlist.[ch].
5250 Added the function silc_idlist_find_server_by_conn into the
5251 files silcd/idlist.[ch].
5253 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * DIE command was renamed to SHUTDOWN. Updated the both code
5258 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5259 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5261 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5264 * Added function silc_server_create_connection function to create
5265 connection to remote router. My server implementation actually
5266 does not allow router to connect to normal server (it expects
5267 that normal server always initiates the connection to the router)
5268 so the CONNECT command is only good for connecting to another
5271 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5274 or some other client was kicked from the channel.
5276 Implemented the handling of the notify type to both client
5279 Implemented silc_server_send_notify_kicked to send the KICKED
5280 notify. It is used to send it to the server's primary router.
5282 * Implemented the KICK command into server and client.
5284 * Added `query' argument to the silc_idlist_get_client function
5285 to indicate whether to query the client from server or not if
5288 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5289 to indicate that the client is not channel founder.
5293 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Removed the rng context from SilcPacketContext structure and
5296 changed that the packet routine uses the Global RNG API.
5298 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Added support for quit message that client can "leave" on the
5301 channel when it quits the SILC. It is ditributed inside the
5302 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5304 Added silc_server_free_client_data that will take the
5305 signoff message as argument.
5307 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5309 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Updated parts of the protocol specification to keep it up
5314 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5317 payloads in one packet.
5319 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5320 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5321 use now the new List flag.
5323 * Also deprecated the following packet types: REPLACE_ID,
5324 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5326 * Added list support for Notify packet in server.
5328 * Added silc_server_send_notify_channel_change to send the
5329 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5330 the silc_server_send_replace_id.
5332 * Added silc_server_send_notify_nick_change to send the
5333 NICK_CHANGE notify type. Deprecates the function
5334 silc_server_send_replace_id.
5336 * Added silc_server_send_notify_join to send the JOIN notify type.
5337 Deprecates the function silc_server_send_new_channel_user.
5339 * Added silc_server_send_notify_leave to send LEAVE notify type.
5340 Deprecates the function silc_server_send_remove_channel_user.
5342 * Added silc_server_send_notify_cmode and
5343 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5344 types. Deprecates the silc_server_send_set_mode function.
5346 * Added SERVER_SIGNOFF notify type to indicate that server has
5347 quit. This means that all clients on the channel from that
5348 server will drop. This can be also used when netsplit happens.
5350 Deprecated REMOVE_ID packet type since it is not needed anymore
5353 Added silc_server_send_notify_server_signoff to send the
5354 SERVER_SIGNOFF notify type. Deprecates the function
5355 silc_server_send_remove_id.
5357 Added also silc_server_send_notify_signoff to send the
5358 SIGNOFF notify type.
5360 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5361 SILC protocol from this day on. Changed the protocol
5362 specification as well.
5364 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5365 notify type. It is used between routers to notify about
5366 topic changes on a channel.
5368 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5371 * Partly updated the protocol specification to comply with the
5372 changes now made. It is still though a bit outdated.
5374 * The JOIN notify type now takes one extra argument <Channel ID>.
5375 The packet used to be destined to the channel but now the
5376 JOIN type may be sent as list thus it is impossible to
5377 destine it to any specific channel. By adding this argument
5378 it is again possible.
5380 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Added CREDITS file. The CHANGES and CREDITS file will appear
5383 in the distribution as well.
5385 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5388 types in the server's silcd/packet_receive.c.
5390 * Implemented CMODE and CUMODE to work in router environment.
5392 * Fixed minor encoding and decoding buglet from the
5393 lib/silccore/silcmode.c.
5395 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5398 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5400 * Changed all SilcConfigServer* and silc_config_server* to
5401 SilcServerConfig* and silc_server_config*, respectively.
5404 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Associated the ID (client or server ID) to the Authentication
5407 Payload to avoid any possibility of forging. Updated the
5408 protocol specification and the code accordingly.
5410 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * The RSA key length is now save to the RsaKey context in the
5413 key generation process in lib/silccrypt/rsa.c. The key length
5414 is now used to figure out the maximum size of the block allowed
5415 to be encrypted/signed.
5417 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5418 is equivalent to the silc_mp_mp2bin but does not allocate any
5421 * Changed silc_mp_mp2bin API to take length argument. If it is
5422 non-zero then the buffer is allocated that large. If zero, then
5423 the size is approximated using silc_mp_sizeinbase, which however
5426 * Created Global RNG API which is global RNG that application can
5427 initialize. After initializing, any routine anywhere in the
5428 code (including library) can use RNG without allocating a new
5429 RNG object. This was done to allow this sort of use of the
5430 RNG in code that has no chance to allocate RNG object. All
5431 applications currently allocate this and many routines in the
5432 library use this. Affected file lib/silccrypt/silcrng.[ch].
5434 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5435 it to use the Global RNG API.
5437 * Defined Authentication Payload into protocol specification that
5438 is used during SILC session to authenticate entities. It is
5439 used for example by client to authenticate itself to the server
5440 to obtain server operator privileges.
5442 Implemented this payload into the lib/silccore/silcauth.[ch].
5443 Implemented also routines for public key based authentication
5444 as the new protocol specification dictates.
5446 Moved definitions of different authentication methods from
5447 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5449 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5450 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5451 silc_pkcs_verify_with_hash functions into the file
5452 lib/silccrypt/silcpkcs.[ch].
5454 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * The client entry's userinfo pointer must be always valid.
5457 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5458 will fail since it requires the userinfo. Now, the userinfo
5459 is allocated as "" if actual userinfo does not exist. Actually,
5460 it must exist and it is totally Ok to drop client connections
5461 that does not announce the userinfo. However, we will make
5462 this workaround for now.
5464 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5465 to return the remote port by socket.
5467 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5470 SILC_SERVER_PENDING_EXEC and added an new macro
5471 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5472 data or when error occurs while processing the pending command.
5474 Added new argument `destructor' into silc_server_command_pending
5475 and to the SilcServerCommandPending object. This destructor is
5476 now called after calling the pending callback or if error occurs
5477 immediately. If error occurs the actual pending callback won't
5478 be called at all - only the destructor. The destructor may be
5479 NULL if destructor is not needed.
5481 All this applies for client library code as well. Similar
5482 changes were made there as well for the pending commands.
5484 In the client, the application must now allocate the
5485 SilcClientCommandContext with the silc_client_command_alloc
5488 * Added reference counter to the SilcServerCommandContext. Added
5489 function silc_server_command_alloc and silc_server_command_dup
5492 Same type of functions added to the client library for the same
5495 * Removed the cmd_ident from IDListData away since it is now
5496 global for all connections. It is the command identifier used
5497 in command sending and with pending commands. The affected file
5500 * Added reference counter to the SilcSocketConnection objecet to
5501 indicate the usage count of the object. The object won't be
5502 freed untill the reference counter hits zero. Currently only
5503 server uses this, and client ignores it. The client must be
5504 set to use this too later. The affected files are
5505 lib/silccore/silcsockconn.[ch]. Added also the function
5506 silc_socket_dup to increase the reference counter.
5508 This was mainly added because it is possible that the socket
5509 is removed underneath of pending command or other async
5510 operation. Now it won't be free'd and proper DISCONNECTING
5511 flags, etc. can be set to avoid sending data to connection that
5512 is not valid anymore.
5514 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5515 the connection. After that it sets SILC_SET_DISCONNECTED.
5516 It is, however, possible that the socket data is not still freed.
5517 The silc_server_packet_process now checks that data is not
5518 read or written to connection that is DISCONNECTED. The socket
5519 get's freed when the reference counter hits zero.
5521 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Changed the client operation API: channel_message operation's
5524 `sender' is now the client entry of the sender, not the nickname
5525 and the `channel' is the channel entry, not the channel name.
5527 In the private_message operation the `sender' is now also the
5528 client entry of the sender not the nickname.
5530 Affected file is lib/silcclient/ops.h and all applications
5531 using the client operations.
5533 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Moved the calling of ops->connect() from connect_to_server_final
5536 into receive_new_id functin since that is the point when the
5537 client is actually allowed to send traffic to network. The
5538 affected file is lib/silcclient/client.c.
5540 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5543 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5544 (if needs broadcasting) instead of broadcasting the packets one
5545 by one which would make a burst in the network traffic.
5547 * Added `broadcast' argument to the functions in silcd/server.[ch]
5548 silc_server_create_new_channel[_with_id] to indicate whether
5549 to send New Channel packet to primary router.
5551 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added new function into the silcd/server.[ch] files:
5554 silc_server_create_new_channel_with_id to create new channel with
5555 already existing Channel ID.
5557 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5558 lib/silccore/silcpacket.h. This packet is used t send list of
5559 Set Mode payloads inside one packet. Server uses this to set
5560 the modes for the channels and clients on those channels, that it
5561 announced to the router when it connected to it. The protocol
5562 specification has been updated accordingly.
5564 * The silc_server_new_channel did not handle the packet coming
5565 from normal server as it normally does not send that. However,
5566 when it announces its channels it does send it. Implemented
5567 the support for that.
5569 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5570 into the file lib/silccore/id.h.
5572 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Fixed memory leaks in the functions silc_idlist_del_client,
5575 silc_idlist_del_channel and silc_idlist_del_server in the file
5576 silcd/idlist.c. All of those leaked like a sieve.
5578 * Fixed some small memory leaks in the client's function
5579 silc_client_notify_by_server.
5581 * Added functions into silcd/server.c: silc_server_announce_clients,
5582 silc_server_announce_channels and silc_server_announce_server.
5583 These functions are used by normal and router server to announce
5584 to its primary router about clients, channels and servers (when
5585 router) that we own. This is done after we've connected to the
5588 These functions effectively implements the following packet types:
5589 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5590 and SILC_PACKET_NEW_ID_LIST.
5592 * Added new functions into the silcd/packet_receive.[ch]:
5593 silc_server_new_id_list, silc_server_new_channel_list and
5594 silc_server_new_channel_user_list to handle the incoming
5595 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5597 * Added support of changing Channel ID in the function
5598 silc_server_replace_id. If the server that announces a channel
5599 to the router already exists in the router (with same name but
5600 with different Channel ID), router is responsible to send
5601 Replace ID packet to the server and force the server to change
5602 the Channel ID to the one router has.
5604 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5605 client that the Channel ID has been changed by the router. The
5606 normal server sends this to the client. Client must start using
5607 the new Channel ID as the channel's ID.
5609 Implemented handling of this new type into lib/silcclient/client.c
5610 into the function silc_client_notify_by_server.
5612 * Added new function silc_idlist_replace_channel_id into the files
5613 silcd/idlist.[ch] to replace the Channel ID.
5615 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Call silc_server_command_identify_check always when processing
5618 the IDENTIFY command in silcd/command.c
5620 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5623 send keepalive packets. The packet can be sent by clients,
5624 servers and routers.
5626 Added function silc_socket_set_heartbeat into the file
5627 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5628 If not set, the heartbeat is not performed. The actual
5629 heartbeat is implemented in the low level socket connection
5630 library. However, application is responsible of actually
5633 Added silc_server_send_heartbeat to send the actual heartbeat
5634 packet into silcd/packet_send.[ch]. Server now performs
5635 keepalive with all connections.
5637 * Added silc_task_get_first function into lib/silcutil/silctask.c
5638 to return the timeout task with shortest timeout. There was a bug
5639 in task unregistration that caused problems. TODO has been
5640 updated to include that task system must be rewritten.
5642 * The client library will now resolve the client information when
5643 receiving JOIN notify from server for client that we know but
5644 have incomplete information.
5646 * Rewrote parts of silc_server_remove_from_channels and
5647 silc_server_remove_from_one_channel as they did not remove the
5648 channel in some circumstances even though they should've.
5650 * Encryption problem encountered in server:
5652 The LEAVE command used to send the Channel Key packet to the
5653 router immediately after generating it. However, the code
5654 had earlier sent Remove Channel user packet but not immediately,
5655 ie. it was put to queue. The order of packets in the router
5656 was that Channel Key packet was first and Remove Channel User
5657 packet was second, even though they were encrypted in the
5658 reverse order. For this reason, MAC check failed. Now, this
5659 is fixed by not sending the Channel Key packet immediately but
5660 putting it to queue. However, this is more fundamental problem:
5661 packets that are in queue should actually not be encrypted
5662 because packets that are sent immediately gets encrypted
5663 actually with wrong IV (and thus MAC check fails). So, packets
5664 that are in queue should be encrypted when they are sent to
5665 the wire and not when they put to the queue.
5667 However, the problem is that the current system has not been
5668 designed to work that way. Instead, the packet is encrypted
5669 as soon as possible and left to the queue. The queue is then
5670 just purged into wire. There won't be any fixes for this
5671 any time soon. So, the current semantic for packet sending
5674 o If you send packet to remote host and do not force the send
5675 (the packet will be in queue) then all subsequent packets to the
5676 same remote host must also be put to the queue. Only after the
5677 queue has been purged is it safe again to force the packet
5680 o If you send all packets immediately then it safe to send
5681 any of subsequent packets through the queue, however, after
5682 the first packet is put to queue then any subsequent packets
5683 must also be put to the queue.
5685 Follow these rules and everything works fine.
5687 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Added new function silc_server_remove_clients_by_server to
5690 remove all client entries from ID list when the server connection
5691 is lost. In this case it is also important to invalidate all
5692 client entires as they hold the invalid server entry. This
5693 fixes fatal bug when server has lost connection and will reconnect
5696 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Made some sanity checks to silc_server_daemonise like to check
5699 whether the requested user and group actually exists.
5701 * Added sanity check to SKE's silc_ske_responder_finish to check
5702 that the public and private key actually is valid.
5704 * Invalidate the client's nickname when receiving Replace ID
5705 packet and the Client ID is being replaced. This means that the
5706 server will query the nickname if someone needs it (client)
5709 * Sort the ID Cache in client library when the ID Cache data
5710 has changed (needs sorting).
5712 * Do not allow for SILC client to create several connections to
5713 several servers. The client does not support windows right now
5714 and generating multiple connections causes weird behaviour.
5716 Irssi-silc client does support windows and can handle several
5717 connections without problems, see: www.irssi.org and SILC plugin.
5719 * Fixed some places where client was added to the IDList. The
5720 rule of thumb is following (in order to get everything right):
5721 If the client is directly connected local client then the
5722 `connection' argument must be set and `router' argument must be
5723 NULL to silc_idlist_add_client function. If the client is not
5724 directly connected client then the `router' argument must
5725 bet set and the `connection' argument must be NULL to the
5726 silc_idlist_add_client function.
5728 * The funtion silc_server_packet_send_local_channel actually did
5729 not check whether the client was locally connected or not. It
5730 does that now. Fixed a bug related to LEAVE command.
5732 * Fixed Remove Channel User payload parsing bug in server's
5733 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5735 * The server's silc_server_save_channel_key now checks also the
5736 global ID list for the channel as it might not be in the local
5737 list. Fixed a bug related to LEAVE command.
5739 * Is this the end of the [<unknown>] buglet that has been lurking
5740 around for a long time? A little for loop fix in server's
5741 silc_server_command_whois_parse that is used by both IDENTIFY
5742 and WHOIS command. At least, this was a clear bug and a cause
5743 of one type of [<unknown>] buglet.
5745 * WHOIS and IDENTIFY commands call the function
5746 silc_server_command_[whois/identify]_check function even if
5747 we are not router server.
5749 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added --with-gmp configuration option. If set the GMP
5752 is always compiled in the SILC source tree. If not set then
5753 it is checked whether the system has the GMP3 installed. If
5754 it has then the GMP won't be compiled (the system's headers
5755 and library is used), if it doesn't have it then the GMP is
5756 compiled in the SILC source tree.
5758 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Changed RSA private exponent generation to what PKCS #1
5761 suggests. We try to find the smallest possible d by doing
5762 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5763 not security fix but optimization.
5765 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Added new config entry [Identity] to fork the server and run
5768 it as specific user and group. A patch from Bostik.
5770 * Imported Dotconf configuration library into lib/dotconf.
5771 This will be used to create the SILC configuration files later.
5772 It will appear in the distsribution after this commit.
5774 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * A big code auditing weekend happening. Auditing code for
5777 obvious mistakes, bugs and errors. Also, removing any code
5780 Removed files for being obsolete:
5782 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5783 inline in the file lib/silcutil/silcbuffer.h)
5785 o lib/silcutil/silcbufutil.c (the header has inline versions)
5787 Changed code to fix possible error conditions:
5789 o The buffer formatting routines now check that the destination
5790 buffer really has enough space to add the data. This applies for
5791 both buffer formatting and unformatting
5792 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5793 unformatting was changed to accomodate following rules:
5794 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5795 sent to the function while XXX_*STRING will not allocate or copy
5796 the data into the buffer. Instead it sets the pointer from the
5797 buffer into the pointer sent as argument (XXX_*STRING used to
5798 require that the pointer must be allocated already). This change
5799 makes this whole thing a bit more consistent and more optimized
5800 (note that the data returned in the unformatting with XXX_*STRING
5801 must not be freed now). The routines return now -1 on error.
5803 o Tried to find all code that use buffer_format and buffer_unformat
5804 and added return value checking to prevent formatting and
5805 especially unformatting errors and possible subsequent fatal
5808 o Changed ske->x and ske->KEY to mallocated pointers in
5809 lib/silcske/silcske.h. Fixed possible data and memory leak.
5811 o Added return value checking to all *_parse* functions. Fixed
5812 many memory leaks as well.
5814 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5815 so that buffer overflows would not happen. All code now also
5816 checks the return value as it can fail.
5818 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Added reconnection support to server if the normal server looses
5821 its connection to the router (for example if router is rebooted).
5822 The server performs normal reconnection strategy implemented
5823 to the server. Affected file silcd/server.c.
5825 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Added new packet type SILC_PACKET_SET_MODE that is used to
5828 distribute the information about changed modes (for clients,
5829 channels and clients channel modes) to all routers in the
5830 network. Updated the protocol specification accordingly.
5832 Added functions into silcd/packet_send.c and
5833 silcd/packet_receive.c: silc_server_send_set_mode,
5834 silc_server_set_mode.
5836 Added new files silcmode.[ch] into lib/silccore that implements
5837 the encoding and decoding of Set Mode Payload. Added new type
5838 SilcSetModePayload. Moved the definitions of different modes
5839 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5841 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Oops, a little mistake in server's connection authentication
5844 protocol. The protocol is not ended with FAILURE but with
5845 SUCCESS if the authentication is Ok. :) Affected file is
5848 * Implemented NICK_CHANGE notify handling in server in the file
5849 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5850 the local clients on the channel. After the changing nickname
5851 in router environment snhould work and the [<unknown>] nickname
5852 should appear no more.
5854 The silc_server_replace_id function that receives the Replace ID
5855 payload now sends the NICK_CHANGE notify type also in the file
5856 silcd/packet_receive.c
5858 * Changed WHOIS and IDENTIFY command to support the maximum amount
5859 of arguments defined in protocol specs (3328 arguments). This
5860 fixed a bug that caused problems when there were more than three
5863 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Added extra parameter, command identifier, to the
5866 silc_client_send_command so that explicit command identifier
5869 Changed that ID list routines uses specific command identifier
5870 when sending WHOIS/IDENTIFY requests to the server so that they
5871 can be identified when the reply comes back.
5873 Affected files lib/silcclient/command.[ch],
5874 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5876 * Added `sender' argument to silc_server_packet_send_to_channel
5877 to indicaet the sender who originally sent the packet to us
5878 that we are now re-sending. Ignored if NULL. Affected file
5879 silcd/packet_send.[ch].
5881 * Added some server statistics support in silcd/server_internal.h
5882 SilcServerStatistics structure and around the server code. Also
5883 send some nice statistics information when client is connecting
5886 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Fixed channel ID decoding in server's JOIN command reply in
5889 silcd/command_reply.c
5891 * Fixed braodcasting of replace ID payload to not to send it if
5892 we are standalone server in silcd/packet_receive.c.
5894 * Fixed all channel message sending routines to not to send
5895 packets to clients that has router set, since they are routed
5896 separately in the same function earlier. Affects file
5897 silcd/packet_send.c and all channel packet sending functions.
5899 * In USERS reply, res_argv[i] are not allocated, the table
5900 is allocated. Thus changed that free the table, not its
5903 * In server's whois_check and identify_check if the client is
5904 locally connected do not send any WHOIS commands - they are not
5907 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Fixed some minor bugs in client when sending WHOIS command. The
5910 arguments was in wrong order.
5912 * Removed statis function add_to_channel from server in
5913 silcd/command.c that was previously used with the joining but
5916 * Tested USERS command in router environment successfully with two
5917 routers, two servers and two clients.
5919 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Reorganized the USERS command and command reply in client library
5922 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5923 When the command is given by user we register a pending command
5924 callback that will reprocess the command after the reply has been
5925 received from the server. When reprocessing the packet we then
5926 display the information. Thus, the USERS information is displayed
5927 now in the command callback instead of in the command reply
5928 callback. The processing of the command is same as previously
5929 when server has sent the command reply in the JOINing process.
5931 * Added to USERS command in silcd/command_reply.c to join the client,
5932 we didn't use to know about, to the channel after we've created
5933 a client entry for it. Also, for clienet we did know already still
5934 check whether it is on the channel or not and add it if not.
5936 * Removed silc_server_command_join_notify as the function and its
5939 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Changed the client's pending command handling to the same as the
5942 server's pending command handling. It is also now possible to
5943 execute command reply functions from other command reply
5944 function as the function callbacks for commands and command
5945 replies are one and same. The pending commands are not static
5946 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5947 in client connection context. Thus, pending commands are server
5948 connection specific as it is convenient.
5950 Changed the function silc_client_command_pending and
5951 silc_client_command_pending_del and added new function
5952 silc_client_command_pending_check. Removed the
5953 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5956 * Added cmd_ident, current command identifier, to the client
5957 connection context in lib/silcclient/client.h to keep track on
5958 command identifiers used in command sending. Client's command reply
5959 function handling now supports the mandatory command identifiers.
5961 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5962 funtions in client to fully support pending command callbacks.
5964 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5965 as one of the arguments to the application in the command reply
5968 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5969 before first releasing SILC but came back. Now it is removed again
5970 and should come back nomore. The FORWARDED flag was used only
5971 by the JOINing procedure by forwarding the command packet to router.
5972 Now, the JOINing procedure has been changed to more generic (due
5973 to various router environment issues) and FORWARDED is not needed
5974 anymore for anything. The protocol specification is yet to be
5977 Now, removed silc_server_packet_forward from server and the flag
5978 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5980 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Renamed NAMES command to USERS command. The NAMES was named that
5983 due to historical reasons. Now it is renamed. Also, rewrote
5984 parts of the USERS command. The nickname list is not sent anymore
5985 by the server. Only Client ID and mode lists are sent in the USERS
5986 command. Changed this also to the protocol specification.
5988 The client now resolves the names and stuff after it receives
5989 the USERS list from the server when joining to the channel.
5991 * WHOIS and IDENTIFY commands has been changed to support multiple
5992 Client ID's per command. One can now search for multiple users
5993 in the network by sending only one WHOIS or IDENTIFY command.
5994 Changed the code and the protocol specifications.
5996 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5997 uses silc_server_command_whois_parse to parse the request. */
5999 * If normal server, do not parse the WHOIS and IDENTIFY requests
6000 before sending it to the router. Saves some time.
6002 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Fixed JOIN command on client library. Wrong number of arguments
6005 used to crash the client.
6007 * Added silc_server_channel_has_global function to check whether
6008 channel has global users or not.
6010 * Added silc_server_channel_has_local function to check whether channel
6011 has locally connected clients on the channel.
6013 * The silc_server_remove_from_one_channel now checks whether the
6014 channel has global users or not after given client was removed from
6015 the channel. It also checks whether the channel has local clients
6016 on the channel anymore. If it does not have then the channel entry
6017 is removed as it is not needed anymore.
6019 * The silc_server_notify now checks on JOIN notify whether the joining
6020 client is one of locally connected or global. If it is global then
6021 the channel has now global users on the channel and that is marked
6022 to the channel entry. Also, it now saves the global client to
6023 global list who is joining and JOINs it to the channel. This is
6024 for normal server, that is.
6026 Changed silc_server_send_notify_on_channel,
6027 silc_server_packet_relay_to_channel and
6028 silc_server_packet_send_to_channel check if we are normal server
6029 and client has router set (ie. global client) do not send the
6030 message to that client, as it is already routed to our router.
6032 * Implemented LEAVE notify type handling in silc_server_notify
6035 * Tested LEAVE command in router environment successfully. Tested
6036 with two routers, two servers and two clients.
6040 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6042 * Implemented SIGNOFF notify type handling in silc_server_notify
6045 * silc_server_remove_id now removes the client entry from all channels
6046 it has joined and thusly sends SIGNOFF notify type.
6048 * Rewrote the NAMES list generation in server by removing two excess
6049 loops. The lists are created now inside one loop.
6051 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * silc_server_remove_channel_user checks now also global list
6054 for channel and client.
6056 * silc_server_new_channel_user checks now both local and global
6057 list for channel and client. Fixed a bug in client id decoding.
6058 Used to decode wrong buffer.
6060 * silc_server_channel_message checks now both local and global
6061 list for channel entry.
6063 * Tested channel joining (hence JOIN) in router environment
6064 successfully. Tested with two routers, two servers and two
6067 * Tested channel message sending in router environment successfully.
6069 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added silc_server_save_channel_key into server.[ch] to save the
6072 received channel key in Channel Key payload processing. It is
6073 also used in JOIN command reply handling.
6075 Equivalent function silc_client_save_channel_key added into
6076 client.[ch] into client library.
6078 * Changed JOIN command reply to send information whether the channel
6079 was created or not (is existing already) and the channel key
6080 payload. Changed protocol specs accordingly.
6082 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6083 the request was sent by ID and not by nickname. Crashed on
6086 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6089 now correctly save the received data.
6091 * silc_server_free_sock_user_data now notifies routers in the
6092 network about entities leaving the network.
6094 At the same time implemented functions silc_server_remove_id
6095 and silc_server_send_remove_id to receive and send REMOVE_ID
6096 packets. The packet is used to notify routers in the network
6097 about leaving entities. The ID removed will become invalid in
6100 * Added function silc_idlist_del_server into server. Removes and
6101 free's server entry from ID list.
6103 * silc_server_private_message function now checks, if we are router,
6104 that the destination ID really is valid ID, naturally.
6106 * In router when NEW_ID packet is received (for new client) the
6107 hash of the Client ID is saved in the ID Cache but the
6108 client->nickname is set to NULL, instead of putting the hash
6111 IDENTIFY command now also checks that client->nickname must be
6112 valid. If it is not if will request the data from the server who
6113 owns the client. Added new function
6114 silc_server_command_identify_check.
6116 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6117 to set the command to already allocated Command Payload.
6119 * Tested private message sending in router environment with two
6120 routers, two servers and two clients. Fixed minor bugs and now
6123 * Fixed segfault from client's NAMES command. Used to crash if
6126 * Forwarded packets must not be routed even if it is not destined
6127 to the receiver. Changed server code comply with this.
6129 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added `require_reverse_mapping' boolean value to ServerParams
6132 structure. If TRUE (not default) the server will require that
6133 the connecting host has fully qualified domain name.
6135 If the reverse mapping is not required and hostname could not be
6136 found the IP address is used as hostname.
6138 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Implemented version string checking to both client and server.
6141 The check is incomplete currently due to the abnormal version
6142 strings used in development version of SILC.
6144 * Changed all command functions in server to use the new
6147 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Changed char *data to unsigned char *data in ID Cache system to
6150 support binary data as ID Cache data. Changed code to support
6151 binary data in lib/silccore/idcache.c.
6153 * Renamed silc_server_packet_relay_command_reply to
6154 silc_server_command_reply as it is normal packet receiving
6155 function. Rewrote the function to accept command replys for
6156 servers and not only for clients.
6158 * Mark remote router always as registered server if we are connecting
6159 to it. Otherwise, commands sent by the router to us are ignored.
6161 * All ID List find routines now returns the ID Cache Entry pointer
6162 as well if requested.
6164 * WHOIS command works now in router environment, tested with two
6165 routers, two servers and two clients.
6167 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6168 in router environment (as it is almost equivalent to WHOIS) but
6169 hasn't been tested thoroughly. Added new functions:
6171 silc_server_command_identify_parse
6172 silc_server_command_identify_send_reply
6173 silc_server_command_identify_from_client
6174 silc_server_command_identify_from_server
6176 * Disabled route cache adding because adding two different ID's with
6177 same IP replaces the old cache entry thus giving wrong route.
6178 The entry->router->connection is always the fastest route anyway
6179 so route cache may not be needed. Of course, new routes maybe
6180 established after receiving the ID when the entry->router->connection
6181 might not be anymore the most optimal.
6183 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Add route cache for received ID for fast routing.
6187 * Added silc_server_packet_route to route received packet on router
6188 that is not destined to us.
6190 * Renamed silc_server_get_route to silc_server_route_get.
6192 * Added id_string and id_string_len fields into SilcServer to
6193 include encoded ServerID for fast comparing without excess
6194 encoding of the ID's.
6196 * Cleaned up WHOIS command on server side. Added following static
6199 silc_server_command_whois_parse
6200 silc_server_command_whois_check
6201 silc_server_command_whois_send_reply
6202 silc_server_command_whois_from_client
6203 silc_server_command_whois_from_server
6205 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6206 arguments in command replies. All command functions should be
6207 updated to use this macro.
6209 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Minor typo fixes on command reply handling on server.
6213 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Added silc_server_command_add_to_channel internal routine to add
6216 the client to the channel after router has created the channel and
6217 sent command reply to the server.
6219 * Added generic silc_server_send_command to send any command from
6222 * Use static buffer with ID rendering instead of duplicating data.
6224 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Fixed a channel user mode bug when joining to a channel server gave
6227 everybody channel founder rights, oops.
6229 * We mark ourselves as the router of the incoming server connection
6230 if we are router ourselves. This way we can check in some packet
6231 sending functions whether it is locally connected server. For
6232 incoming router connections we put NULL.
6234 * For router sending packets locally means now always sending the
6235 packet cell wide; to local clients and local servers. For normal
6236 server sending packet locally means sending it to only local
6239 * Fixed the JOIN command to really work in router environment. If the
6240 channel is created it is always created by the router. Router is
6241 also responsible of making the initial joining to the channel,
6242 sending JOIN notify to the sending server and distributing
6243 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6244 does not exist server doesn't do anything else but forward the
6245 command to the router which performs everything.
6247 * Added silc_server_send_channel_key function to send the Channel Key
6250 * Added silc_server_create_channel_key to create new channel key. The
6251 channel key is now re-generated everytime someone joins or leaves
6252 a channel, as protocol dictates. Note: channel->key_len is the
6255 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6258 packet_receive.[ch] to separate packet sending and receiving
6259 routines. The server.[ch] now includes everything else including
6260 actual packet processing (writing and reading data) and other
6263 Renamed silc_server_private_message_send_internal to
6264 silc_server_send_private_message. The routine is still though
6265 used only to relay private messages as server does not send
6266 private messages itself.
6268 Renamed silc_server_new_channel to silc_server_create_new_channel
6269 and added new function sicl_server_new_channel that handles the
6270 incoming New Channel packet. Added also new sending function
6271 silc_server_send_new_channel to send New Channel Payload.
6273 * Added new function silc_server_notify to process incoming notify
6274 packet to the server/router. Server may then relay the notify
6275 to clients if needed.
6277 * Added new function silc_server_new_channel_user to process incoming
6278 New Channel User packet. Router will redistribute the packet and
6279 send JOIN notify to its local clients and locally connected servers
6280 if needed. Normal server will send JOIN notify to its local client
6281 on same channel when received this packet. Added also corresponding
6282 sending function silc_server_send_new_channel_user to sent the
6285 * Added boolean route argument to send_notif_to_channel and
6286 packet_send_to_channel functions to attempt to route the packet
6287 if it is TRUE and send only locally if it is FALSE.
6289 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * silc_server_replace_id now broadcasts the received replace ID
6292 packet if it is not broadcast packet already. The router must
6293 broadcast to inform other routers about changed ID.
6295 * Added backpointer to server's router into SilcServer context in
6296 silcd/server_internal.h.
6298 * Fixed silc_server_packet_broadcast to send correct broadcast
6301 * The channel key is now distributed to the local client as soon
6302 as it is received from the router (in router environment) so that
6303 no other packet may be sent for the channel until client has
6306 * silc_server_remove_channel_user now broadcasts the received
6307 Remove Channel User packet if it is not broadcast packet already.
6308 The router must broadcast to inform other routers about removed
6311 * Added users field into SilcPacketContext that is a reference count
6312 of the context. One can increase the reference count by calling
6313 silc_packet_context_dup which is now changed to just increase the
6314 reference count instead of duplicating the data. The reference
6315 count is decresed by calling silc_packet_context_free that will
6316 free the data after the reference count hits zero.
6318 For now on the packet context and everything allocated into it
6319 (including the raw packet from network) must be freed by calling
6320 the new silc_packet_context_free function. Added also new function
6321 silc_packet_context_alloc that must be used now to allocate the
6322 context. This also means that if a routine is asynchronous from
6323 silc_[client/server]_packet_parse_type the packet context must
6324 be duplicated by calling silc_packet_context_dup. Otherwise it
6325 gets free'd after silc_[client/server]_packet_parse_type returns.
6326 Also, one must remember that if packet is duplicated then its
6327 reference count must be decresed by calling the free function as
6328 many times as it was duplicated.
6330 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6331 from both client and server.
6333 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Made joining to a channel working in router environment.
6337 * Cleaned up JOIN command on server side and create function
6338 silc_server_command_join_channel internal routine to make the
6341 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Changed silc_command_pending list to SilcDList. Also, added
6344 `ident' field to SilcServerCommandPending structure to identify
6345 the reply and to call correct callback.
6347 Added silc_server_command_pending_check function to replace the
6348 corresnponding macro. The silc_command_pending list is not
6351 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6352 to set identifier to previously allocated Command Payload. It
6353 is used to set identifier for command when resending Command
6356 * Added silc_command_payload_encode_payload to encode Command
6357 Payload buffer from SilcCommandPayload structure.
6359 * Added silc_argument_payload_encode_payload to encode Argument
6360 payload buffer from SilcArgumentPayload structure.
6362 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Changed WHOIS command to support router connection on server side.
6365 The whois request is always sent to router unless the server is
6366 standalone server. After server has received the reply from the
6367 router will it send the reply to the client.
6369 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6370 broadcast received broadcast packet. The function is used only
6371 by router. The broadcast packet is always sent to the router's
6374 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6375 render given ID to printable string, for log files for example.
6377 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Made basic router to router connections working. At least they
6380 can now connect to each other but nothing really works the way
6381 they are supposed - yet.
6383 * Added new initiator token to RouterConnection configuration
6384 file in silcd/serverconfig.[ch]. It is used to tell whether we
6385 are the initiator to the remote router or whether we'll expect
6386 the other end to connect.
6388 * Moved registering of listener task to silc_server_init, hence
6389 the server starts listenning as soon as it is run, even if it
6390 does not have connections to other routers. Let's see how well
6393 * Changed default connection retry timeouts for more suitable in
6396 * Removed cipher and such arguments from silc_idlist_add_client
6397 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6398 Added new function silc_idlist_add_data to add the keys and stuff
6401 * Added SilcIDListData structure and added it to SilcClientEntry
6402 and SilcServerEntry as their first field in the structure. This
6403 way we can explicitly cast the ID entries to the SilcIDListData
6404 structure and get common data for the entries. In past, we had
6405 to first check what type of connection it is and then cast it to
6406 correct ID entry type. Now, we can directly cast the opaque
6407 pointer to the SilcIDListData (no matter what ID entry it actually
6408 is) and get the data needed.
6410 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6413 in some circumstances even if threre were timeout tasks, though not
6414 IO tasks, but tasks anyway. Now fixed.
6416 * Defined SilcServerConnection structure to hold connection specific
6417 stuff about directly connected servers and routers. The definition
6418 is currently in silcd/server_internal.h. I thought about having
6419 a bit more important role fro this struct but for now it is used
6420 only when connecting to other server (or router actually).
6422 * Added connecting retry support in server when connecting to
6423 router(s). The retry feature implement exponential backoff
6424 algorithm. Also, added SilcServerParams structure to hold default
6425 parameters for server. For now, it include these retry settings
6426 and are hard coded. After server is moded to be as Silc Server
6427 Library this structure will be more important.
6429 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Changed client librarys channel->clients table to SilcList and
6432 changed code accordingly.
6434 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Changed client's channel table to SilcList and changed code
6437 accordingly. Also changed SilcChannelClientEntry to include back-
6438 pointer to the channel so that client entry can use that structure
6439 as list as well and we have fast cross-reference to the channel.
6440 This change dramatically decreased the complexity of channel
6441 handling with client entry and vice versa (removed one extra
6442 loop when searching for channel entry from many functions).
6444 * Changed server->sim from table to SilcDList and changed code
6447 * NAMES command can now be used from user interface. It will show
6448 the user list on the channel, neatly.
6450 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6451 Code now saves realname of the user if it becomes available.
6453 * Renamed configure.in to configure.in.pre and made ./prepare
6454 script to automatically add correct version string to
6455 configure.in which it creates from configure.in.pre.
6457 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * NAMES command reply now shows users mode with the nickname when
6462 * Moved silc_client_ch[u]mode[_char] functions from
6463 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6464 place sucks, they are utility functions and should be in some
6467 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6469 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6472 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added TRQ (efficient deque and list library) into lib/trq. This is
6477 a very good list library that is currently used in the SILC. Defined
6478 SilcList API over the library because I didn't like the API very
6479 much. See lib/trq/silclist.h for the API and examples of how to
6480 use the API. Fixed various places in the code to use the new
6481 SilcList API. The SilcList is meant for lists that has a structure
6482 already defined as a list. It is not suitable to add just some
6483 context to the list (in TRQ, the context is the list actually).
6485 So, I defined SilcDList that can be used for the purpose where
6486 predefined list structure does not exit. This can be used as
6487 such list. Now some context just can be added to the SilcDList.
6488 Currently this list is not used in the SILC just yet, though there
6489 are a lot places where this can replace dynamically allocated
6490 tables and I will fix these places, later, to use SilcDList.
6491 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6492 and use TRQ internally).
6494 Also fixed some annoying warning messages that the original TRQ
6495 code generated. Also minor changes to TRQ's Makefile.in.
6497 * Added support for querying by Client ID to both WHOIS and
6498 IDENTIFY commands into server, as required by the protocol.
6500 * Removed method function pointers from SilcBuffer structure. They
6501 weren't used to anything and just increased the context size for
6502 no good reason. This change also made silc_buffer_alloc and
6503 silc_buffer_free functions inline functions.
6505 * Disabled command flooding detection support until it's fixed so
6506 that it accepts commands in but does not execute them more than once
6509 * Added silc_net_localhost(), to return local hostname, into
6510 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6511 that must be initialized before calling silc_client_init.
6513 * Added new function: silc_server_send_notify_on_channels to send
6514 notify messages to all channels client has joined. It is assured
6515 that the message is sent only once per client.
6517 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6518 lib/silcutil/silcutil.[ch] as silc_format function. The new
6519 function is generic and is used by server as well, not only by
6520 the logging routines.
6522 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6523 the provided version string was not acceptable. Added new function:
6524 silc_ske_check_version into lib/silcske/silcske.h. The function
6525 must be implemented by the application (client or server) and it
6526 does not reside in the SKE library. The function checks the version
6527 string remote end sent.
6529 * Added back pointers (to opaque context and to SilcSocketConnection)
6530 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6532 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6533 duplicate packet context structure.
6535 * Changed `notify' client operation to send same arguments as client
6536 receives from server except for ID's. ID's are mapped to correct
6537 ID entry and that is returned. Also, if channel entry is not sent
6538 by server but the notify is for channel the channel entry is sent
6539 to application (otherwise application doesn't know that it is for
6540 channel (library gets it from packet's Destination ID)).
6542 * Added silc_client_remove_from_channels into client library to
6543 remove a client from all channels it has joined to. Used when
6544 received SIGNOFF notify from server. Added also new function
6545 silc_client_replace_from_channels to replace old ID entry with
6546 new ID entry on all channels. Used when received NICK_CHANGE
6549 * Fixed ID Cache list handling in silc_idlist_get_client in
6550 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6551 to get (or query) client by ID.
6553 * Updated TODO list.
6555 * Added connection authentication status message defined by the
6556 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6557 support for these into the code in client and server side.
6559 * Added generic function silc_client_send_command to send any command
6560 with variable argument list. Application should use this function
6561 to send commands if the command functions provided by the library
6562 does not suite for the application's user interface needs.
6564 * Added new `failure' client operation. Application is notified about
6565 received failure packet if client is executing a protocol. In this
6566 case the protocol's execution has failed.
6568 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6569 is required by the protocol.
6571 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6572 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6575 * Added status flag to SilcSKE object to indicate realtime status
6576 of the SKE protocol.
6578 * Application receives now exactly same command reply arguments as
6579 the library receives from server. However, if ID is received the
6580 corresponding ID entry is returned to the application (eg. Client
6581 ID is mapped to correct SilcClientEntry entry and that is returned).
6582 Changed command_reply client operation due to this change.
6584 * Changed all ID's in commands and in command replys as ID Payloads.
6585 Change affected both client and server side codes.
6587 All ID's sent in SILC network (with execption of ID's in SILC
6588 Packet header) are sent in ID Payload to support variable length
6591 * Server now notifies nick changes and notifies all clients on
6592 the channels about the new nickname (about the new Client ID,
6595 * Implemented CMODE command to change channel modes. Supports all
6596 channel modes defined by the protocol specs except ban and invite
6597 lists. (Also, private channel key mode is supported but support for
6598 setting private channel key in client is missing, thus, this mode
6599 has no effect on client side (except that server requires that the
6600 client uses private channel key and normal channel traffic does not
6603 Also, invite mode works per se, but INVITE command does not work
6604 yet correctly, so you can set channel as invite only channel but
6605 inviting clients to the channel does not work (it is yet to be
6606 thought what's the best way to do it).
6608 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6609 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6610 Implemented CUMODE command to change user's mode on the channel.
6611 Supports all modes defined by the protocol specs.
6613 * Added NAMES command reply to return users modes on the channel.
6615 * Removed unnecessary and slow ciphers from lib/silccrypt.
6617 * Set SO_KEEPALIVE option to connection sockets by default.
6619 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6621 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6622 redefined the Notify Payload into protocol specs.
6624 * Added silc_id_payload_parse_id to get ID directly from raw
6627 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6630 accept searching by Client ID as well.
6632 * Added support for LEAVE and SIGNOFF notify types in client library.
6634 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6635 to parse ID Payload from raw data.
6637 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Added flags parameter into silc_ske_assemble_security_properties
6640 function in lib/silcske/silcske.[ch].
6642 * Changed notify client operation to fit better for notify messages
6643 sent by server. The notify payload received from server is now
6644 passed to the application (after parsing it to SilcNotifyPayload).
6645 It is application's responsibility to retrieve the arguments
6646 from the payload and show the message the way it wants. The message
6647 sent by server is implementation specific.
6649 * Changed public keys to comply with the protocol specification.
6650 Old public keys are not supported anymore and are not compatible.
6652 * Removed nickname from Channel Payload as the latest draft removed
6653 it. The client must resolve the nickname from the NAMES command
6654 reply received when it joined the channel.
6656 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6658 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6660 * Fixed some errors in protocol specification drafts.
6662 * Created lib/silccore/silcnotify.c to implement Notify Payload
6663 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6664 generic payloads described by protocol specifications. The file
6665 includes implementations for ID Payload and Argument Payload.
6667 * Changed Command Payload implementation to use the new Argument
6668 Payload. Changed command_xxxx_payload to command_payload_xxxx
6669 to comply with SILC coding conventions.
6671 * Added suppport for Argument Payload handling in Notify Payload
6672 implementation as protocol requires it. Added the new support
6673 into server and client lib as well.
6675 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6677 * Added support for multiple nicknames on same channel. [n] is
6678 added locally to the nickname if there are more than one same
6679 nicknames on the channel.
6681 * Server now sends all nicknames that matched WHOIS request.
6682 Client also shows the list received from server.
6684 * Added TOPIC command to client side. User can now set and show
6685 current topic on channel.
6687 * Added MOTD command to client and server. Also, server sends the
6688 motd when client connects to the server.
6690 * Changed version strings to comply ISO 8601.
6692 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Fixed protocol error handling in client library. It should now
6695 cope even if the SKE fails for some reason.
6697 * Made new protocol specification drafts for submitting to IETF.
6699 * Implemented TOPIC command to server in silcd/command.c.
6701 * Added two new notify types into lib/silccore/silcnotify.h:
6702 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6703 notify nickname change and topic setting/change on a channel.
6705 * API change of command_reply operation in client library. The
6706 application gets now the status type received from server as well.
6708 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6712 * Cras fixed and optimized the packet handling even further and
6713 it should work now. Minor change to the prototype of function
6714 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6716 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Added new function into lib/silcutil/silcschedule.[ch]:
6719 silc_schedule_with_fd to select() a specified fd. The function
6720 returns after timeout expires or data arrives or goes. The
6721 function is used by packet routines to wait that all data is
6722 received from network.
6724 * Fixed data reading from network in lib/silccore/silcpacket.c.
6725 The code now assures that all data is read from the fd and then
6726 continues packet processing. This was a bug fix since the code
6727 used to drop some data in some circumstances.
6729 * Added new function into lib/silcclient/client.[ch]:
6730 silc_client_start_key_exchange to start key exchange after
6731 connection has been established to server. The code internally
6732 now uses this funtion but its main purpose was to provide it
6733 for applications that perform their own connecting. After
6734 application has created a connection it merely calls this
6735 function to start the key exchange between client and server.
6736 The library takes care of everything else after that.
6738 Updated also lib/silcclient/README to explain the usage of
6741 * Do not send to application information that connection has
6742 been established. Application gets notified it by connect
6745 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Applied cras's patch to add silc_schedule_one function. The
6748 function runs scheduler once and returns.
6750 * Fixed the scheduler after cras messed it up. The timeout
6751 handling works now as it's supposed to work.
6753 * Added into lib/silccore/ silcnotify.h to include notify
6754 message types support. Changed silc_server_send_notify*
6755 functions, in server.[ch], to support those new notify types.
6756 Added the support for the notify types into client library,
6757 as well. Added new notify client operation into ops.h in
6760 * Changed silc_server_packet_send_to_channel to send normal
6761 packets instead of just channel message packets. The function
6762 is now used to send the notify packets to channels. It is not
6763 used to send channel message packets anymore, as server never
6766 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6767 va_arg()s as it seems to require it nowadays. I guess, if SILC
6768 is compiled with older va_arg() the new code should work anyway.
6770 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Splitted core library. Core library (lib/silccore) includes
6773 now only SILC protocol specific core (and common) components.
6774 Created new utility library (lib/silcutil) that includes more
6775 generic purpose stuff. The stuff for util library was taken
6776 from the old core library. This was minor and easy split.
6778 * Created SILC Client Library (lib/silcclient) that includes
6779 implementation of the SILC client without user interface. This
6780 was major move from silc/ directory. The code has been changed
6781 so that it is transparent towards the user interface. The
6782 silc/ directory includes now the same user interface as before
6783 and it uses the new client library. Read lib/silcclient/README.
6784 Basicly, the client library performs everything else related
6785 to SILC except user interface handling. Also, configuration
6786 files are considered to be part of user interface and library
6787 does not handle them.
6789 This change also changed a lot of structures, function naming etc.
6790 Most important change was that SilcClientWindow object was
6791 renamed to SilcClientConnection in the client library. Created
6792 also new file lib/silcclient/ops.h. Also added new files
6793 silc/local_command.[ch] and silc/client_ops.[ch].
6795 All these changes were made to make it easier for user interface
6796 designers to create what ever user interface for the SILC client
6799 It is also expected that the server will be moved to lib
6800 directory as well and SILC Server Library will be created;
6801 sometimes in the future.
6803 * Removed Local commands from lib/silccore/silccommand.h as
6804 they are application specific and new client library does not
6805 handle any of those anymore.
6807 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6808 old client implementation in silc/.
6810 * Added support for callback functions in SILC_LOG_* macros.
6811 Application can now set its own callbacks that will be called
6812 instead of using the default functions that will always print
6813 the debug messages to stderr (or stdout). Also, debugging can
6814 now be disabled by setting silc_debug to FALSE and re-enabled by
6815 setting it to TRUE. Note, that logging will still work even
6816 if debugging is disabled.
6818 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6819 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6820 silc_log_reset_debug_callbacks.
6822 * To enable debugging in silc client one must give now -d
6823 option on command line.
6825 * Changed silc_schedule_init to automatically allocate task queues
6826 if they are not allocated before calling it.
6828 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Added GMP 3.1 into math library.
6832 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6835 a channel in SILC network. The packet is used by servers and
6836 routers to notify other routers that user has left a channel.
6837 This little feature was missing until now. Added the feature
6838 to protocol specification as well.
6840 Added functions: silc_server_send_remove_channel_user and
6841 silc_server_remove_channel_user into server.[ch].
6843 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6844 lib/silccore/silcpacket.h. However, they are not implemented
6847 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Fixed joining to a channel and sending channel messages
6850 between server and router. The channel message sending should
6851 now work inside a cell.
6853 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * Fixed the private message sending between server and router.
6856 The private message sending should now work inside a cell.
6858 * Added silc_server_replace_id into server.[ch] to replace
6859 existing ID in the SILC network.
6861 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6862 and silc_idlist_replace_server_id into idlist.[ch] in server.
6864 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Fixed the server to server connections. Server can again now
6867 connect to router. Router to router connections probably does
6870 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Added dynamic protocol registering support. Now protocols can
6873 registered and unregistered on the fly. Patch by cras.
6875 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Added lib/contrib directory to hold routines that some platforms
6878 don't have but are needed by SILC.
6880 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6881 into lin/contrib to provide getopt() and getopt_long() for
6882 those who don't have it.
6884 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Added AWAY command to client. When away message is set and
6887 client receives a private message packet the client automatically
6888 replies to the sender with the away message.
6890 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6891 bug seemed to be the cause of recent problems when compiling
6894 * Added version detection support to SKE protocol specification
6895 and added the new changes to the SKE implementation as well.
6896 There were other minor changes in the SKE protocol as well.
6898 Many changes in lib/silcske/silcske.[ch] and in
6899 lib/silcske/payload.[ch].
6901 * Added ^U functionality, clear input line. Patch from cras.
6903 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6905 * Mainly small bugfixes on core library. Fixed some debugging
6906 logging and buffer overflow in silclog.c.
6908 * Updated config.sub and config.guess on the distribution tree.
6910 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Added command lagging support in server. Client may execute
6913 commands now only once in two seconds.
6915 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6917 * Optimized packet reception. MAC computation and checking is now
6918 also more optimized. A lot previously duplicated code is now
6919 used as generic by both client and server.
6921 * Fixed key pair generation in clientutil.c
6923 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Added into lib/silccore/silcbufutil.[ch] new function;
6926 silc_buffer_realloc.
6928 * Moved generic packet sending/encryption functions to
6929 lib/silccore/silcpacket.[ch] from client and server. Some
6930 rewriting of the functions.
6932 * Moved all generic packet reception/decryption functions to
6933 lib/silccore/silcpacket.[ch] from client and server. The
6934 packet processing is now much cleaner in both client and server.
6935 These were major changes in both client and server.
6937 * Created many common functions in server to do packet sending.
6938 Previously code were duplicated a lot, this has been removed
6941 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Rewrote major parts of the ID cache system. Don't know
6944 whether it is better now or not but at least the API is more
6947 * Major rewrite on ID cache stuff on client because of the ID
6948 cache API changes. Added idlist.c to client.
6950 * Also major rewrite on ID cache stuff on server as well.
6951 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6952 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6953 in hand, instead they are all put into the ID cache system now.
6954 All server_idlist_* routines uses ID cache now instead of
6955 traversing its own lists (those lists does not exist anymore).
6956 SilcIDList though still exists. Also, SilcXXXEntry's are
6959 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Finally made the SKE implementation compliant to the protocol
6962 specification. All mp integers are now binary encoded as
6963 opposed being HEX encoded.
6965 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6968 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6969 functions: silc_[encode/decode]_pem. Also added function
6970 silc_encode_pem_file to PEM encode with newlines ('\n') for
6973 * SILC public keys are now encoded either PEM or binary. Same
6974 option is for private keys as well. By default private keys
6975 are binary encoded and public keys PEM encoded. Silly HEX
6976 encoding were removed.
6978 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6979 function to create fingerprints.
6981 * Fixed a bug in SHA1; does not change the original data anymore.
6983 * Partly implemented INFO command on client and server side.
6984 Fixed CLEAR command. Changes to SERVER command; show current
6985 server(s) when giving command without arguments. Added
6986 VERSION command to client.
6988 * Added check to server that unregistered connections cannot
6989 execute commands (unless it is specificly allowed).
6991 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Fixed screen refresh.
6995 * Fixed channel joining bug from client. On some circumstances
6996 client tried to join to a channel it had already joined.
6998 * Added public key verification process into client's protocol.c.
6999 The client now verifies the public key from user and saves
7000 it into ~./silc/serverkeys/ directory.
7002 Added into: clientutil.[ch]: silc_client_verify_server_key.
7004 * Changed SKE protocol's silc_ske_initiator_finish function
7005 to accept callback function that verifies the received public
7006 key. Removed old silc_ske_verify_public_key function.
7008 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7011 silc_pkcs_private_key[_data]_set.
7013 * Made the password and public authentication more cleaner in
7014 server's protocol.c.
7016 * Removed historic and obsolete protocol `channel_auth' from
7017 both client and server.
7019 * Removed wrong way of sending command status messages from
7020 server to client in server's command.c. The old way violated
7021 protocol specification.
7023 Changes to silccore/silccommand.[ch]: removed
7024 silc_command_encode_status_payload -> not needed anymore,
7025 changed silc_command_encode_payload_va to accept extra
7026 argument on variable argument list. The argument type must
7027 now be provided to the function. Also, added new function:
7028 silc_command_encode_reply_payload_va which is same as
7029 normal command_encode_payload_va except command status type
7030 is provided as extra argument.
7032 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Added ~./silc directory handling. The directory includes the
7035 public and private keys for the client.
7037 Added silc_client_check_silc_dir, silc_client_create_identifier
7038 and silc_client_load_keys.
7040 * Implemented SILC protocol compliant public key. Added public
7041 and private key saving to and loading from files.
7043 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7044 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7045 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7046 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

7054 * Added silc_server_get_route (route.[ch]) to get connection
7055 data for the fastest route for given ID.
7057 * Implemented INVITE command on client and server. The command
7058 were re-defined in the SILC Protocol Specification and the
7059 implementation now complies with the specification.
7061 * Implemented PING command on client and server.
7063 * Implemented NAMES command on client and server. The server side

7077 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
