29 keepalive_secs, reconnect_count, reconnect_interval,
30 reconnect_interval_max, reconnect_keep_trying and
31 require_reverser_lookup. Added ConnectionParam block, and
32 implemented the connection parameters when connecting as
33 initiator and when accepting connections as responder.
35 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
36 whether given configuration value has been given already.
38 Affected files silcd/serverconfig.[c], server.[c].
40 * Splitted the doc/example_silcd.conf.in. Separated the crypto
41 algorithm parts and created new file silcalgs.conf, that
42 is now included from the example_silcd.conf.in.
44 * Optimized the silc_server_connect_to_router_second to take
45 the connection configuration object from the SilcServerConnection
46 object instead of finding it during the connecting phase.
47 Added the configuration object to SilcServerConnection struct.
48 Affected files silcd/server_internal.h, server.c.
50 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

62 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
64 * Unified the serverconfig.[ch]'s helper function interface.
65 Affected file silcd/serverconfig.[ch].
67 * Removed doc/example_silc.conf.in since it is redundant.
68 The make install will now install irssi/silc.conf file.

71 config file, allowing both public key and passphrase based
72 authentication to be set at the same time.
74 Added `prefer_passphrase_auth' setting in config file which
75 can be used to set to prefer passwd auth if both passwd and
76 public key is set. If not set, public key is preferred.
77 This has effect only when being initiator (responder will try
80 Added support for authentication with passphrase and public key
81 at the same time. The passphrase is tried first always since
82 it is faster to check.
84 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
86 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
88 * Merged the new SILC Config library, with the server parsing

128 hash algorithm. Affected file lib/silccrypt/silcrng.c.
130 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
132 * Fixed the file transfer's key agreement payload to include
133 zero port also if the hostname is NULL because it could not
136 Call file transfer monitor callback now also if error occurs
137 during key agreement protocol.
139 Changed the silc_client_file_send interface to return the
140 SilcClientFileError instead of session id. The session ID
141 is returned into pointer provided as argument.
143 Check that the file exists locally before sending the
144 file transfer request at all.
146 Affected file lib/silcclient/client_ftp.c, silcapi.h.

158 file lib/silcutil/silclog.c.
160 * Fixed the channel message payload decryption in the function
161 silc_channel_message_payload_decrypt to not modify the original
162 buffer before it is verified that the message decrypted
163 correctly. Otherwise, next time it is called with correct
164 channel key it won't encrypt since the payload is corrupted.
165 Affected file lib/silccore/silcchannel.c.
167 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

179 * Fixed a bug in hash table internal routine for traversing
180 the table with foreach callback. The current entry may
181 become invalid in the callback but it was referenced after
182 the callback returned.
184 Do not allow auto rehashing of hash table during the
185 silc_hash_table_foreach operation, for same reasons as it is
186 not allowed for SilcHashTableList. Affected files are
187 lib/silcutil/silchashtable.[ch].
189 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
191 * Defined DLLAPI into silcincludes.h and silcwin32.h for

195 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed private message handling. It used some old code that
198 caused the client to crash. Affecte file is
199 lib/silcclient/client_prvmsg.c.
201 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Added function silc_client_add_channel,
204 silc_client_replace_channel_id, and removed functions
205 silc_client_new_channel_id and silc_idlist_get_channel_by_id
208 * Added cross reference of the joined channels to the
209 SilcClientEntry, and changed the SilcChannelEntry's
210 users list to SilcHashTable. The affected files are
211 lib/silcclient/idlist.[ch].
213 * Fixed a bug in hash table tarversing. While the hash table
214 is traversed with SilcHashTableList the table must not be
215 rehashed. It is now guaranteed that auto rehashable tables
216 are not rehashed while tarversing the list. Also defined that
217 silc_hash_table_rehash must not be called while tarversing
218 the table. Added function silc_hash_table_list_reset that must
219 be called after the tarversing is over. The affected files are
220 lib/silcutil/silchashtable.[ch].
222 * Changed all hash table traversing to call the new
223 silc_hash_table_list_reset in server and in client library.
225 * Added function silc_client_on_channel to return the
226 SilcChannelUser entry if the specified client entry is joined
227 on the specified channel. This is exported to application as
228 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
230 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
232 * Fixed founder regaining problem with JOIN command on normal
233 server. The notify for mode change must be sent always and
234 not only if !cmd->pending. Affected file silcd/command.c.
236 * Fixed the WHOWAS command's reply sending to support the
237 lists correctly. Affected file silcd/command.c.
239 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
241 * When sending JOIN command to router for processing the
242 sender's old command identifier was not saved back to the
243 sender's command context, fixed now. The affected file is
246 * Create the key in JOIN command of the router did not return
247 the channel key, added check for this. Affected file is
250 * Fixed a channel ID update bug in JOIN command reply. Do
251 not directly upgrade the ID but call the function
252 silc_idlist_replace_channel_id if the ID was changed.
253 Affected file silcd/command_reply.c.
255 * Fixed memory leaks from command calling if it would fail.
256 Affected file silcd/command.c.

263 new silclist.h and silcdlist.h, all extern inline changed to
266 * Removed dotconf from lib/dotconf, not needed anymore.
268 * Removed TRQ from lib/trq, not needed anymore.
270 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
271 with server connections. Later this will be configurable
272 in config file after new config file is done. Affected file
275 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
277 * Fixed a crash in server related to channel announcements.
278 Affected file silcd/server.c.
280 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
282 * Fixed memory leaks in silc_server_create_new_channel*
283 functions. Affected file silcd/server.c.
285 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
286 which ID was changed. This way the router will send the
287 user list for the channel again, and server won't be in
288 desync in some rare circumstances. Affected file is
289 silcd/packet_receive.c.
291 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
293 * Check for NULL socket pointer in the function

300 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
302 * Fixed some header addition to Toolkit distribution in
303 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
305 * Added lib/silcclient/client_ops_example.h as an template
306 file for application programmers to quickly start using
307 the SilcClientOperation functions in their application.
308 Updated the lib/silcclient/README as well to tell about this
309 nice file made available.
311 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
313 * Call silc_server_remove_from_channels when removing client
314 entry when NO_SUCH_CLIENT_ID was received. Affected file
315 is silcd/command_reply.c.
317 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
319 * Added server & router operator statistics updating. Affected
320 file silcd/packet_receive.c and silcd/command.c.
322 * Fixed the SERVER_SIGNOFF notify handling on normal server
323 not to save the history information for clients. Same was
324 fixed earlier in remove_clients_by_server function, but not
325 here. Affected file silcd/packet_receive.c.
327 * Raised the default connection-retry count from 4 to 7 in
328 server. Affected file silcd/server.h.
330 * Cancel any possible reconnect timeouts when we start the
331 key exchange. Affected file silcd/server.c.
333 * Do not reconnect on connection failure when SCONNECT was
334 given. Affected files silcd/server.[ch].
336 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
340 * Fixed the NICK command to always give the unformatted
341 nickname to the one giving the NICK command. If unformatted
342 nickname is cached already it will be formatted and the
343 local entry will always get the unformatted nickname.
344 Affected file lib/silcclient/idlist.c.
346 * Fixed some double frees from client library commands.
347 Affected file is lib/silcclient/command.c.
349 * Fixed CUMODE command in server to assure that no one can
350 change founder's mode than the founder itself, there was a
351 little bug. Affected file silcd/command.c.
353 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
355 * Removed the SilcClientCommandDestructor from the client
356 libary, it is not needed anymore. Affected files are
357 lib/silcclient/silcapi.h, command[_reply].[ch],
358 client_notify, idlist.c.
360 * Fixed GETKEY command to first resolve client, and then
361 resolve the server only if the client was not found, instead
362 of resolving both at the same time. Affected file is
363 lib/silcclient/command.c.
365 * Added silc_client_start_key_exchange_cb and lookup the
366 remote hostname and IP address before starting the key
367 exchange with server. The affected file is
368 lib/silcclient/client.c.
370 * The server's public key is now saved using the IP address
371 of the server and not the servername for the filename.
372 The hostname public key filename is checked as an fall back
373 method if the IP address based filename is not found.
375 Fixed the GETKEY command to save the fetched server key
378 Print the remote server's hostname now when new key is
379 received during connection process. Affected file is
380 irssi/src/silc/core/client_ops.c.
382 * Return always our own public key to the client if it asks
383 for it with GETKEY command. Affected file silcd/command.c.
385 * Removed the use_auto_addr variable from default config
386 file since it was in wrong section. Affected file is
389 * Fixed TOPIC_CHANGE notification to not route it when it
390 was sent using silc_server_send_notify_to_channel function.
391 Affected file silcd/command.c.
393 * Fixed silc_server_send_notify_kicked to send the kicker's
394 Client ID also, it was missing. Affected files are
395 silcd/command.c, silcd/packet_send.[ch].
397 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * Do not save client history information in SERVER_SIGNOFF.
400 Fixes the bug in normal server that it does not detect
401 the client becoming valid after the server becomes back
402 online. Affected file silcd/server_util.c.
404 * Added `sock_error' field into the SilcSocketConnection
405 context. When error occurs during socket operation (read
406 or write) the error is saved. Added also new function
407 silc_socket_get_error to return human readable socket error
408 message. Affected files are lib/silcutil/silcsockconn.[ch],
409 lib/silcutil/unix/silcunixsockconn.c, and
410 lib/silcutil/win32/silcwin32sockconn.c.
412 * The server now prints the socket error message in the
413 signoff for client. Affected file silcd/server.c.
415 * Fixed the `created' channel information sending from router
416 to server in JOIN command. Checks now whether the channel
417 really was created or not and set it according that.
419 Fixed the JOIN command to use the client entry's current
420 ID during the joining procedure instead of the one it sent
421 in the command (it is checked though), since it can change
422 between the packet processing and command processing, and
423 would just case unnecessary pain in the client end. Affected
424 file silcd/command.c.
426 * Fixed a channel key payload sending to use correct channel
427 ID when the server was forced to change the channel's ID by
428 router. Router sent the key payload with the old Channel ID.
429 Affected file silcd/packet_receive.c.
431 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Call silc_server_save_channel_key only if the key payload
434 was provided in the JOIN command's command reply. Affected
435 file silcd/command_reply.c.
437 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Fixed silc_mp_sizeinbase to return the value correctly with
440 MPI. Affected file lib/silcmath/mp_mpi.c.
442 * Fixed the stop_server signal to correctly stop the scheduler
443 and gracefully stop the server when SIGTERM or SIGINT signals
444 are received. Affected file silcd/silcd.c.
446 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
448 * Simple handling of TERM and HUP signals. Also added some log
449 flushing call around. Affected file is
452 * Fixed small bugs in silclog.c. Now buffering output will take
453 effect after 10 seconds since startup: This will ensure that
454 no important startup messages are lost. Also output redirection
455 will preserve original format ([Date] [Type] message).
456 Affected file is lib/silcutil/silclog.c.
458 * Added two options to the config file, in the logging section:
459 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
460 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
462 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Do not print the warning about log files not being initialized
465 more than once to avoid excess logging. Affected file is
466 lib/silcutil/silclog.c.
468 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
469 the SIM copying in make install in Makefile.am.pre.
471 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
473 * Rewritten silclog APIs. Globally interesting changes follows:
474 silc_log_set_files() changed to silc_log_set_file().
475 silc_log_set_callbacks() changed to silc_log_set_callback().
476 ROBOdoc documented silclog header file.
477 SilcLogCb now returns bool to wether inihibit the default
478 handler or not (to keep the old behaviour return always TRUE).
479 The new APIs should also fix the problem of the
480 silcd_error.log file that was written in the current directory.
483 Log files streams will remain opened after silc_log_set_file()
484 call, means less CPU usage notably on high traffic servers.
485 File streams are now full buffered, and flushed to the disk
486 every 5 minutes, lesses HD activity and CPU usage.
487 Messages can be redirected, allowing admins to configure
488 one single logfile for all server messages.
489 the silc_log_quick global variable to activate fast-logging.
490 Affected files lib/silcutil/silclog.[ch]
492 * Changed some code to conform new silclog APIs. Affected
493 files are doc/example_silcd.conf.in, silcd/server.c
494 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
497 * Fixed a memory leak that could occur in some situations.
498 Affected file silcd/serverconfig.c.
500 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
502 * Added the silc_client_del_client to remove the client from
503 all channels as well. Affected file lib/silcclient/idlist.c.
505 * Fixed the client library to correctly remove the client
506 from all channels when the client entry is being destroyed.
507 Affected file lib/silcclient/client_notify.c, command.c.
509 * Added auto-nicking support to the client library. If the
510 applicatio now sets client->nickname it will be sent to the
511 server after connecting by the library. This way for example
512 SILCNICK (or IRCNICK) environment variables will have effect
513 and always change the nickname automatically to whatever
514 it is wanted. Affected file lib/silcclient/client.[ch].
516 * Renamed silc_server_command_bad_chars to the
517 silc_server_name_bad_chars and moved it to the
518 silcd/server_util.[ch]. Added also new function
519 silc_server_name_modify_bad to return nickname that
520 includes bad characters as new nickname without those
521 bad characters. This check and modify is now used in
522 silc_server_new_client when the username is initially set
523 as nickname, so it must be checked to be valid nickname.
524 Affected file silcd/packet_receive.c.
526 * The nickname length is now taken from the packet for real
527 and not trusted to strlen() since it clearly can return
528 wrong length for nickname including bad characters. This
529 also applies to channel names. Affected file silcd/command.c.
531 * Removed the lib/silcsilm/modules directory. Modules are now
532 compiled into the lib/silcsim. Fixed the copying of the
533 modules to follow symbolic links in Makefile.am.pre.
535 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Fixed silc_string_regexify list creation. Fixes bugs with
538 BAN and INVITE commands in server. The affected file is
539 lib/silcutil/unix/silcunixutil.c.
541 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
543 * Removed the command destructor entirely from the server's
544 command and command reply routines. It is not needed, and
545 its usage was buggy and caused crashes. Affected files are
546 silcd/command[_reply].[ch].
548 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Cancel protocol and NULL sock->protocol if timeout
551 occurred during protocol. Affected file silcd/server.c.
553 * Cancel protocol timeouts always before calling the final
554 callback, to assure that after final callback is called
555 no other state will be called for the protocol anymore.
556 Affected file silcd/protocol.c.
558 * Print error log if incoming connection configuration could
559 not be found. Affected file silcd/server.c.
561 * Fixed JOIN command to correctly save the founder mode
562 to the client on normal SILC server, when the channel
563 was created by the router. Affected file silcd/command.c.
565 * Fixed LIST command (hopefully) to send correct reply
566 packets. Affected file silcd/command.c.
568 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
570 * The silc_packet_receive_process now returns FALSE if the
571 read data was invalid packet, and TRUE if it was ok.
573 The server now checks that if unauthenticated connection
574 sends data and its processing fails the server will close
575 the connection since it could be a malicious flooder.
577 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
579 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Make sure the warning about error opening a log file is
582 printed only once and not everytime it fails (produces
583 too much useless log). Affected file lib/silcutil/silclog.c.
585 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
587 * Made the silc_server_daemonise() function more readable.
588 Affected file silcd/server.c.
590 * Pid file is now optional, the user may comment it out from
591 the config file. Removed define SILC_SERVER_PID_FILE, we
592 don't need a default any longer. Affected file
593 configure.in.pre, lib/Makefile.am.pre.
595 * Make some use of the pid file. The server now dies at startup
596 if it detects a valid pid file on his path. The server would
597 die anyway in this circumstance, because of the bind() failure.
598 Affected file silcd/silcd.c.
600 * No longer compiling lib/dotconf.
602 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Fixed JOIN command parsing not to crash. Affected file
605 lib/silcclient/command.c.
607 * Fied the NICK_CHANGE notify to add the new client entry
608 even it is resolved. This removes an <[unknown]> nick
609 thingy bug in the client. Affected file is
610 lib/silcclient/client_notify.c.
612 * Do not try to allocate 0 bytes (efence does not like it)
613 in lib/silccore/silccomand.c when encoding payload.
615 * Do not take IRCNICK as nickname in Irssi SILC client since
616 it is not possible to set nickname before hand connecting
617 the server (TODO has an entry about adding auto-nicking
620 * Changed the silc_server_command_pending to check whether
621 there already exists an pending entry with the specified
622 command, command identifier and pending callback. This is
623 to fix IDENTIFY and WHOIS related crashes that may register
624 multiple pending commands with same identifier. Affected
625 file silcd/command.c.
627 * Fixed the server to reconnect to the router even if it
628 was already reconnecting and EOF was received. This to
629 fix a possibility that the server wouldn't ever try to
630 auto-reconnect to the router. Affected file silcd/server.c.
632 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Fixed the server's password authentication to use the
635 length of the locally saved password, and not the one
636 sent in the packet. Affected file silcd/protocol.c.
638 * Fixed same password authentication problem in the
639 Authentication Payload handling routines in
640 lib/silccore/silcauth.c.
642 * Yet another password authentication problem fixed with
643 channel password handling in silcd/command.c.
645 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
647 * If first character of string in silc_parse_userfqdn is '@'
648 then do not parse it. Affected file is
649 lib/silcutil/silcutil.c.
651 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
653 * Fixed minor bug in IDENTIFY command reply sending, which
654 caused various weird problems during JOIN when it was
655 resolving names for users. Affected file silcd/command.c.
657 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
659 * Fixed the IDENTIFY command reply sending to chech better valid
660 clients. It was possible to send incomplete list of replies.
661 Affected file silcd/command.c.
663 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Added silc_client_command[s]_[un]register functions now to
666 dynamically register the commands in client library. Removed
667 the static table of commands. This allows the client library
668 to call commands without causing the application to know about
669 what commands library has called.
671 Removed the INFO command reply kludge to detect when the command
672 was called by library. Now library use its own command reply
673 function for INFO command.
675 Added function silc_client_command_call to call a command.
676 Application can use it to call command, not access the structure
679 Now all commands that are sent by the client library (not
680 explicitly sent by application) use own command reply functions.
682 Affected files around lib/silcclient/ and in
683 irssi/src/silc/core/.
685 * Fixed the WHOIS command reply sending to chech better valid
686 clients. It was possible to send incomplete list of replies.
688 Fixed the WHOIS and IDENTIFY to send the request to router
689 if normal server did not do it and did not find any results.
691 Affected file silcd/command.c.
693 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Moved the internal data from SilcClient context into its
696 own file, not accesible to application. Affected files
697 lib/silcclient/client.h and lib/silcclient/client_internal.h,
698 and other files in client library.
700 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
702 * Added doc/examples installation target in Makefile.am.pre.
705 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
707 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
708 commands the found client entry will be removed from the
709 cache, after notifying application about the error. Affected
710 file lib/silcclient/command_reply.c.
712 * Changed the /MSG to check for exact nickname user gave, and
713 not let `nick' match `nick@host' if it is only one found. Now,
714 user must type the exact nickname (like nick@host2) even if
715 there are no more than one same nicks found. This is to avoid
716 a possibility of sending nickname to wrong nickname since
717 `nick' could match `nick@host'. Affected file is
718 irssi/src/core/silc-servers.c.
720 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Do not print "you are now server operator" or similar when
723 giving /away command. Affected files are
724 irssi/src/silc/core/client_ops.c, silc-servers.h.
726 * Made the silc_server_command_pending_error_check to send
727 the same command reply payload it received back to the
728 original sender of the command. This way all arguments
729 that was received by the server will be received by the
730 client too. Affected file silcd/command.c.
732 * Added the silc_idcache_add to return the created cache entry
733 to a pointer. Affected file lib/silccore/silcidcache.[ch].
735 * Add global clients to expire if they are not on any channel.
736 This is because normal server will never know if they signoff
737 if they are not on any channel. The cache expiry will take
738 case of these entries. This is done by normal servers only.
739 The affected files are silcd/command_reply.c,
740 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
742 * If server receives invalid ID notification for WHOIS or
743 IDENTIFY and the ID exists in the lists, it is removed.
744 Affected file silcd/command_reply.c.
746 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
747 in client then client entry that it matches is searched and
748 the nickname is printed on the screen for user. Affected
749 file irssi/src/silc/core/client_ops.c.
751 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Use cache entry expire time in the LIST command reply to
754 purge old entries from the cache after the LIST command
755 reply has been received. This way we don't have non-existent
756 entries in the cache for too long. Affected file is
757 silcd/command_reply.c.
759 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
761 * If we are normal server, and we've not resolved client info
762 in WHOIS or IDENTIFY from router, and it is global client,
763 we'll check whether it is on some channel. If it is not
764 then we cannot be sure about its validity and will resolve it
765 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
766 file silcd/command.c.
768 * Search channel by name (if possible) rather than by ID
769 in IDENTIFY command's command reply. Affected file is
770 silcd/command_reply.c.
772 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Distribute to the channel passphrase in CMODE_CHANGE notify.
775 Updated specs and implemented it. Affected file silcd/command.c,
776 silcd/packet_send.c and silcd/packet_receive.c.
778 * Implemented the <founder auth> payload handling in the JOIN
779 command. If provided all conditions for channel joining
780 except requirement to provide correct passphrase can be
781 overrided by the channel founder. Updated the protocol specs.
782 Affected file silcd/command.c.
784 Added support for founder auth in JOIN command in client
785 library. Fixed the parsing of the JOIN command now to support
786 all options as they should be. The affected file is
787 lib/silcclient/command.c.
789 * Optimized the WHOIS and IDENTIFY commands to send the request
790 to router only if it includes nicknames or other names. If
791 they include only IDs then check the local cache first before
792 routing. Affected file is silcd/command.c.
794 * Added channels topic announcements. Affected file is
795 silcd/packet_receive.c and silcd/server.c.
797 * Fixed the silc_server_send_notify_topic_set to really destine
798 the packet to channel. Affected file silcd/packet_send.c.
800 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
801 library. Affected file lib/silcclient/client_notify.c.
803 * Added UMODE announcements. Affected file silcd/server.c.
805 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Memory leak fixes in:
809 lib/silcutil/silcsockconn.c
810 lib/silcske/silcske.c
813 lib/silccrypt/silcpkcs.c
814 lib/silccore/silccommand.c
815 lib/silccore/silcidcache.c
820 * ROBOdoc documented the lib/silcske/groups.h file and a
821 bit changed the interface for better.
823 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
825 * Update the client entry context in the ID cache after
826 nick change. Affected file lib/silcclient/command.c.
827 Fixes the CUMODE command when regaining founder privileges,
828 and a little WHOIS problem.
830 * Fixed silc_net_gethostbyname to correctly call the
831 inet_ntop. Affected file lib/silcutil/silcnet.c.
833 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
835 * Added IPv6 support checking to the configure.in.pre, added
836 also --enable-ipv6 option to override the check. Affected
837 file configure.in.pre.
839 * The silc_thread_create now calls the start function
840 directly if threads support is not compiled in. Removes
841 ugly #ifdef's from generic code. Affected files are
842 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
844 * Added silc_net_gethostby[name/addr]_async to asynchronously
845 resolve. Affected files are lib/silcutil/silcnet.[ch].
847 * Added support for rendering IPv6 based server, client and
848 channel IDs. Affected file lib/silcutil/silcutil.c.
850 * Added support for creating IPv6 based server IDs. Affected
851 file is silcd/serverid.c.
853 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
855 * Added silc_net_gethostby[addr/name] into the
856 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
857 routines. Added silc_net_is_ip[4/6]. Affected file is
858 lib/silcutil/unix/silcunixnet.c. All routines that take
859 address as argument now supports both IPv4 and IPv6 addresses.
861 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
863 * Fixed LIST command reply sending in server. Affected file
866 * Server now sends the kicker's client ID in the KICK notify
867 to the kicked client. Affected file silcd/command.c.
869 * The client library now parses the kickers client ID and
870 UI displays it. Affected files lib/silcclient/client_notify.c
871 and irssi/src/silc/core/silc-channels.c, module-formats.c.
873 * Made all payload parsing function prototypes consistent.
874 They all take now const unsigned char * and uint32 pair as
875 the payload data instead of SilcBuffer. Changes all around
876 the source tree. Other unsigned char* -> const unsigned char*
877 changes around the tree as well.
879 * Optimized SFTP client and server packet sending not to
880 allocate new buffer for each packet but to recycle the
881 first allocated buffer. Affected files are
882 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
884 * Optimized the SFTP client to use SilcList instead of
885 SilcDList for requests, because it is faster. Affected file
886 is lib/silcsftp/sftp_client.c.
888 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
889 into lib/silccore/silcid.[ch].
891 Renamed silcpayload.[ch] into silcargument.[ch].
893 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
895 * If client entry is deleted with active key agreement
896 session, abort the session.
898 The silc_client_abort_key_agreement now calls the completion
899 callback with new SILC_KEY_AGREEMENT_ABORTED status.
901 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
904 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Don't use __restrict in older GCC's. Affected file is
907 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
909 * silc_net_localhost now attempts to reverse lookup the
910 IP/hostname. Affected file lib/silcutil/silcnet.c.
912 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
913 command. It can be used to gain founder privileges at
914 the same time when joining the channel.
916 Defined that the SILC_NOTIFY_TYPE_KICKED send the
917 kicker's client ID as well. Updated protocol specs.
919 Defined that the server must send SILC_COMMAND_IDENTIFY
920 command reply with error status to client who sent
921 private message with invalid client ID.
923 Updated the protocol specification.
925 * Added silc_server_send_command_reply to send any
926 command reply. Affected file silcd/packet_send.[ch].
928 * Added silc_id_payload_encode_data to encode ID payload
929 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
931 * The server now send IDENTIFY command reply with error
932 status if client ID in private message is invalid. Affected
933 file silcd/packet_receive.c.
935 * Save the server key file with server's IP address in
936 the filename instead of hostname. The affected file is
937 irssi/src/silc/core/client_ops.c.
939 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
941 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
944 * Added libtool support for compiling shared objects in
945 lib/silcsim. Affected file configure.in.pre and
946 lib/silcsim/Makefile.am. Original patch by cras.
948 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Pid file configuration, and server's config file fixes
951 patch by toma. Updated CREDITS file.
953 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Fixed silc_client_channel_message to not try to decrypt
956 the message twice if it resolved the destination client
957 information. This could cause of dropping one channel
958 message. Affected file lib/silcclient/client_channel.c.
960 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Added silc_client_run_one into lib/silcclient/silcapi.h and
963 lib/silcclient/client.c. This function is used when the SILC
964 Client is run under some other scheduler, or event loop or
965 main loop. On GUI applications, for example this may be
966 desired to used to run the client under the GUI application's
967 main loop. Typically the GUI application would register an
968 idle task that calls this function multiple times in a second
969 to quickly process the SILC specific data.
971 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
973 * Fixed silc_server_drop() for dropping the supplementary
974 groups as well, this could cause a security hole on some
977 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

983 to run server on foreground. A patch by debolaz.
984 Affected files silcd/server.c, silcd/silcd.c.
986 * Fixed MOTD to return the MOTD file server name. Affected
987 file silcd/command.c.
989 * Added INFO command reply handling to the Irssi SILC Client.
990 Affected file irssi/src/silc/core/client_ops.c.
992 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Fixed the silc_idcache_list_* routines to really support
995 the dynamic list. Fixes a crash. Affected file is
996 lib/silccore/silcidcache.c.
998 * Fixed the LIST command reply to really call LIST command's
999 pending callbacks. Affected file silcd/command_reply.c.
1001 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Update conn->local_entry->nickname after giving NICK
1004 command. Affected file lib/silcclient/command.c.
1006 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1008 * Added the [pid] option to the silcd configuration file
1010 Affected files: serverconfig.[ch] and silcd.c
1012 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Save fingerprint in WHOIS command reply in server.
1015 Affected file silcd/command_reply.c.
1017 * Fixed NICK commands pending callback registration.
1018 Affected file lib/silcclient/command.c.
1020 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Use ++server->cmd_ident when sending commands in server,
1023 instead of random number. Affected file silcd/command.c.
1025 * Fixed GETKEY command reply to call actually GETKEY pending
1026 command callbacks. Affected file silcd/command_reply.c.
1028 * A bit stricter check for nicknames. Check for same nickname
1029 in NICK command also. Affected file silcd/command.c.
1031 * Do not call INFO command everytime client ID changes, only
1032 during first connecting. Affected file lib/silcclient/client.c.
1034 * Set the new nickname only after successful command reply for
1035 NICK command is returned by server. Affected file
1036 lib/silcclient/command.c.
1038 * Remove nicknames from nicklist during server_signoff notify.
1039 Should fix /NAMES bit more. The affected file is
1040 irssi/src/silc/core/silc-channels.c.
1042 * Added `fingerprint' field to the SilcIDListData in the
1043 silcd/idlist.h to hold the fingerprint of the client's
1046 Send the fingerprint of the client's public key in WHOIS
1049 Affected files silcd/command.c, and silcd/idlist.[ch].
1051 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1052 create fingerprint from given data.
1054 * Show the fingerprint of the client's public key in WHOIS.
1055 Affected files irssi/src/module-formats.[ch] and
1056 irssi/src/silc/core/client_ops.c.
1058 * Format the multiple same nicknames also during JOIN and
1059 NICK_CHANGE notifys. Affected file is
1060 lib/silcclient/client_notify.c.
1062 * Do not print error on screen for invalid private message
1063 payload since it can come if someone is sending private
1064 messages with wrong key. Affected file
1065 lib/silccore/silcprivate.c.
1067 * Fixed multiple concurrent /PING crash. Affected file
1068 lib/silcclient/command.c.
1070 * Changed the wrong ID encoding. All IP addresses must be
1071 in MSB first order in encoded format. They were encoded
1072 wrong and was in LSB format. Affected files are
1073 silcd/serverid.c, lib/silcutil/silcutil.c.
1075 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1077 * Call the `connect' client operation through the scheduler
1078 in case of error. Affected file lib/silcclient/client.c.
1080 * Call the `failure' client operation even if the error
1081 occurred locally during a protocol. Affected file is
1082 lib/silcclient/protocol.c.
1084 * Added support of sending LIST command to router from normal
1085 server. This way normal server can get list of all channels
1086 in the network too. Fixed the channel list sending in the
1087 server too. Affected files are silcd/command.c, and
1088 silcd/command_reply.[ch].
1090 * Added silc_server_update_channels_by_server and
1091 silc_server_remove_channels_by_server. They are used during
1092 disconnection of primary router and in backup router protocol.
1093 Affected file silcd/server_util.[ch], silcd/server.c and
1094 silcd/server_backup.c.
1096 * Fixed channel adding to global list in IDENTIFY command
1097 reply in server. Affected file silcd/command_reply.c.
1099 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * If the incoming packet type is REKEY or REKEY_DONE process
1102 that packet always synchronously. Fixes yet another MAC
1103 failed error on slow (dialup) connections. Affected file
1104 lib/silcclient/client.c and silcd/server.c.
1106 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Call check_version SKE callback for initiator too. Affected
1109 file lib/silcske/silcske.c.
1111 * Implemented fix for security hole found in the SKE that was
1112 fixed in the specification few days back; the initiator's
1113 public key is now added to the HASH value computation.
1114 Added backwards support for the old way of doing it too, for
1115 old clients and old servers. Affected file is
1116 lib/silcske/silcske.c.
1118 * Enabled mutual authentication by default in SKE. If initiator
1119 is not providing mutual authentication the responder will
1120 force it. This will provide the proof of posession of the
1121 private key for responder. The affected files are
1122 lib/silcclient/protocol.c and silcd/protocol.c.
1124 * Do not cache anymore the server's public key during SKE.
1125 We do mutual authentication so the proof of posession of
1126 private key is done, and if the server is authenticated in
1127 conn auth protocol with public key we must have the public
1128 key already. Affected file silcd/protocol.c.
1130 * Added new global debug variable: silc_debug_hexdump. If
1131 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1132 file lib/silcutil/silclog.[ch].
1134 * Fixed compilation warning due to char * -> const char *.
1135 Affected files lib/silcutil/silcnet.h, and
1136 lib/silccore/silcauth.[ch].
1138 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Fixed CMODE command when new channel key was created. If
1141 the creation failed the old key was removed. Next time giving
1142 same command would crash the server since the old key was
1143 freed already. Affected file silcd/command.c.
1145 * Fixed the silc_server_announce_get_channels to not crash
1146 on reconnect. Affected file silcd/server.c.
1148 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Added silc_log_set_debug_string function to set a regex
1151 string to match for debug output. Only the function names,
1152 or filenames matching the given debug string is actually
1153 printed. This way it is possible to filter out those debug
1154 strings that user is not interested in.
1156 Fixed a bug in silc_string_regexify.
1158 Affected files lib/silcutil/silclog.[ch], and
1159 lib/silcutil/unix/silcunixutil.c.
1161 * Changed the -d options in both server and Irssi SILC client
1162 to take the debug string as argument. Affected files
1163 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1165 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Added silc_hash_babbleprint to create a Bubble Babble
1168 Encoded fingerprint. The encoding is developed by Antti
1169 Huima (draft-huima-babble-01.txt), and it creates human
1170 readable strings out of binary data. Affected file
1171 lib/silccrypt/silchash.[ch].
1173 * Print the babble print now in addition of fingerprint as well
1174 in Irssi SILC client. Affected files are
1175 irssi/src/fe-common/silc/module-formats.[ch],
1176 irssi/src/fe-common/silc/core/client_ops.c.
1178 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Fixed a security problem found in SKE. The initiator's
1181 public key too is now added to the HASH hash value creation
1182 which is signed by the responder to create the SIGN value.
1183 This will prevent anyone in the middle to lie to the responder
1184 about the initiator's public key. If this is done now, the
1185 man in the middle will get caught. Updated the protocol
1188 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Better installation directory handling. Configure module
1191 paths and other paths automatically to example_silc* files
1192 in doc/. A patch by toma.
1194 * Fixed compiler warning from MPI library, and from SILC RNG.
1197 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1198 It can be configured with ./configure. A patch by toma.
1200 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Find correct make to use in prepare-clean. A patch by
1203 toma. Affected file prepare-clean.
1205 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1207 * Added irssi variables use_auto_addr, auto_bind_ip,
1208 auto_bind_port and auto_public_ip.
1210 * Changed the interface for silc_client_send_key_agreement
1211 in lib/silcclient/silcapi.h
1215 irssi/src/silc/core/silc-core.c
1217 lib/silcclient/silcapi.h
1218 irssi/src/silc/core/silc-channels.c
1219 lib/silcclient/client_keyagr.c
1222 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Added silc_pkcs_public_key_compare to compare two
1225 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1227 * Check that the client who set the founder mode on the
1228 channel is the same client that is giving the founder
1229 mode to itself. It is done by comparing the saved public
1230 key (it is saved even in the authentication is passphrase).
1231 Affected file silcd/command.c.
1233 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Do not process packet for disconnected socket connection.
1236 Affected file lib/silccore/silcpacket.c.
1238 * Process the DISCONNECT packet through scheduler in the
1239 client library. Affected file lib/silcclient/client.c.
1241 * Fixed the silc_client_packet_parse to not to increase
1242 the packet sequence number if the conn->sock and the
1243 current socket connection is not same. This can happen
1244 for example during key agreement when the conn includes
1245 multiple socket connections (listeners). Affected file
1246 lib/silcclient/client.c.
1248 * The sender of the file transfer request now provides also
1249 the pointer (listener) for the key exchange protocol. If
1250 the listener cannot be created then it sends empty key
1251 agreement and lets the receiver provide the listener.
1253 Added `local_ip' and `local_port' arguments to the
1254 silc_client_file_send. If they are provided they are used,
1255 if not then it will attempt to find local IP address, if
1256 not found or bind fails then the remote client will provide
1259 Affected files are lib/silcclient/client_ftp.c and
1260 lib/silcclient/silcapi.h.
1262 * Extended the FILE SEND command to support defining the
1263 local IP and port for key exchange listener. They are
1264 optional. Affected file irssi/src/silc/core/silc-servers.c.
1266 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Defined to WHOIS command reply the sending of fingerprint
1269 of the client's public key (if the proof of posession of the
1270 corresponding private key is verified by the server).
1271 Updated to the protocol specification.
1273 * Added support of receiving the client's public key's
1274 fingerprint in command reply in client library. Affected
1275 file is lib/silcclient/command_reply.c, and
1276 lib/silcclient/idlist.[ch].
1278 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Do not send over 128 chars long nickname to the server
1281 in NICK command. Affected file lib/silcclient/command.c.
1283 * Do not send over 256 chars long channel names to the server
1284 in JOIN command. Affected file lib/silcclient/command.c.
1286 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Assure that silc_server_close_connection cannot be called
1289 twice for same socket context. Affected file is
1292 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Send error message to application if opening file for
1295 writing during file transfer fails. Affected file is
1296 lib/silcclient/client_ftp.c.
1298 Remove all file transfer sessions for a client that we're
1299 removing from ID cache.
1301 Affected file is lib/silcclient/client_ftp.c.
1303 * Fixed silc_net_addr2bin to return correct address. Affected
1304 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1306 * Fixed file transfer session removing on signoff notify.
1307 Affected file irssi/src/silc/core/silc-servers.c.
1309 * Added the SilcClientFileError to be returned in the monitor
1310 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1311 Affected file lib/silcclient/silcapi.h.
1313 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Fixed a crash in silc_client_ftp_free_sessions and
1316 silc_client_ftp_session_free_client. Affected file
1317 lib/silcclient/client_ftp.c.
1319 * Added `disabled' field in the SilcChannelEntry in the server
1320 to indicate if the server entry is disabled. Affected file
1321 silcd/idlist.h, silcd/command[_reply].c.
1323 * SILC server adds now /var/run/silcd.pid everytime it is
1324 started. Affected file silcd/silcd.c.
1326 * Added silc_server_packet_send_clients to send a packet to
1327 the provided table of client entries. Affected file
1328 silcd/packet_send.[ch].
1330 * Fixed a crash in client resolving in client_prvmsg.c in
1331 client library. Affected file lib/silcclient/client_prvmsg.c.
1333 * Do not actually remove the client directly from ID cache
1334 during SERVER_SIGNOFF, but invalidate it. This way we
1335 preserve the WHOWAS info for the client. Affected file
1336 silcd/server_util.c.
1338 * Fixed SERVER_SIGNOFF notify handling in the server. The
1339 server is now able to process incoming SERVER_SIGNOFF notify
1340 for a server that it doesn't even know about. It will remove
1341 the clients provided in the notify. Affected file
1342 silcd/packet_receive.c.
1344 * Check for partial packet in data queue after every packet that
1345 was found from the queue. Return and wait for more data if
1346 there is partial data in queue. Affected file is
1347 lib/silccore/silcpacket.c.
1349 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Added SilcClietFileError enum to indicate error in
1352 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1353 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1354 Affected files lib/silcclient/silcapi.h and
1355 lib/silcclient/client_ftp.c.
1357 * Check that newsize in silc_buffer_realloc is larger than
1358 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1360 * Added better monitor of file transfers. It now monitors
1361 key agreement protocol during the file transfer too. Added
1362 error reporting too. Affected files
1363 irssi/src/silc/core/silc-servers.c,
1364 irssi/src/fe-common/silc/module-formats.[ch].
1366 * Wrote a help file for FILE command.
1368 * Added silc_rng_global_get_byte_fast to get not-so-secure
1369 random data as fast as possible. Random data is read from
1370 /dev/urandom if available and from the SILC RNG if not
1371 available. It is used in padding generation. Affected file
1372 lib/silccrypt/silcrng.[ch].
1374 * All packets in client library are now processed synchronously.
1375 Optimized packet processing a lot. Affected file
1376 lib/silcclient/client.c.
1378 * All server connection packets are processing synchronously
1379 now in server, to optimize packet processing. Affected file
1382 * Include files are installed now only in Toolkit distribution
1383 if make install is given. Affected files: all Makefile.am's.
1385 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Assure that silc_client_notify_by_server_resolve does not
1388 resolve the client information multiple times. If it cannot
1389 be found by the first it cannot be found at all. Affected
1390 file lib/silcclient/client_notify.c.
1392 * Fixed WHOWAS command reply calling. Affected file
1393 lib/silcclient/command_reply.c.
1395 * Removed all references to silc_idlist_get_client from the
1396 Irssi SILC client since that call is internal call used by
1397 the library. The Irssi SILC client will use now client
1398 retrieval functions found in silcapi.h.
1400 * Fixed a bug in resolving nickname info before sending
1401 private message. It used freed memory. Affected file
1402 irssi/src/silc/core/silc-servers.c.
1404 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Assure my_channels statistics cannot go negative in server.
1407 Affected files silcd/server.c, silcd/server_util.c.
1409 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1413 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Win32 Toolkit changes. Affected files

1419 lib/sftp/sftp_fs_memory.c.
1421 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Added silc_net_localip to return local host's IP address.
1424 Affected file lib/silcutil/silcnet.[ch].
1426 * If key exchange or rekey protocol is active for a connection
1427 parse all packets syncronously since there might be packets
1428 in packet queue that we are not able to process without first
1429 processing packets before them. Affected file silcd/server,
1430 lib/silcclient/client.c.
1432 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1433 whether library should continue processing the packet.
1434 Affected file lib/silccore/silcpacket.h.
1436 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1437 SilcSFTPMonitorData to SFTP server to monitor various
1438 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1439 lib/silcsftp/sftp_server.c.
1441 * Added silc_file_size to return file size. Affected file

1444 * Implemented the file transfer support for the client library.
1445 Added preliminary support for simple client to client one-file
1446 transmission. Affected file lib/silcclient/client_ftp.c,
1447 lib/silccilent/client.[ch].
1449 * Added new local command FILE to the Irssi SILC Client.
1450 It is used to perform the file transfer. It has subcommands
1451 SEND, RECEIVE, SHOW and CLOSE. Affected files
1452 irssi/src/silc/core/client_ops.c,
1453 irssi/src/silc/core/silc-server.[ch].
1455 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Relay the SILC_PACKET_FTP in the server. Affected files
1458 silcd/server.c and silcd/packet_receive.c.
1460 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Renamed silc_file_read and silc_file_write to functions
1463 silc_file_readfile and silc_file_writefile. Added function
1464 silc_file_open and silc_file_close. Affected files
1465 lib/silcutil/silcutil.[ch].
1467 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Resolve the client info when received private message or
1470 channel message for a client which nickname we don't know.
1471 Affected files lib/silcclient/client_prvmsg.c and
1472 lib/silcclient/client_channel.c.
1474 * Do not crash in /KEY if client is not connected. Affected
1475 file irssi/src/silc/core/silc-channels.c.
1477 * Added SilcClientStatus field to the SilcClientEntry in the
1478 lib/silcclient/idlist.h.
1480 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1481 is incomplete and is being resolved, it won't be resolved
1484 Make sure also that USERS command reply does not resolve
1485 twice information. Affected file is
1486 lib/silcclient/command_reply.c.
1488 Make sure that silc_client_get_clients_by_list does not
1489 resolve twice same information.
1491 * Check for valid client->id in the silc_server_free_client_data.
1492 Affected file silcd/server.c.
1494 * Fixed /GETKEY nick@server not to crash if the server entry
1495 is not found. Affected file lib/silcclient/command.c.
1497 * Fixed the silc_server_check_cmode_rights to check the
1498 requested modes correctly. Affected file silcd/command.c.
1500 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Better checks for non-printable chars in nick added.
1503 Affected file silcd/command.c.
1505 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Call the silc_server_udpate_servers_by_server in the
1508 primary router that comes back online in the backup resuming
1509 protocol. Otherwise it routes packets wrong. Affected file
1510 silcd/server_util.[ch], silcd/server_backup.c.
1512 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1515 lib/silcutil/silcbuffmt.[ch].
1517 * Redefined the SILC packet header to include the padding
1518 length. Affected file lib/silccore/silcpacket.[ch].
1520 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1521 length for maximum padding up to 128 bytes). Affected
1522 file lib/silccore/silcpacket.h.
1524 * Removed all backwards support for old 0.5.x MAC thingies.
1525 The SILC packet header change makes it impossible to be
1526 backwards compatible.
1528 * Send the ENDING packet with timeout in the backup resuming
1529 protocol. This is to assure that all routers has connected
1530 to the primary router. Affected file silcd/server_backup.c.
1532 * Changed the RNG to take the first IV from random data. It
1533 used to take it from zero actually. Changed the RNG also
1534 to use /dev/urandom during session. /dev/random is used
1535 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1537 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * Changed the SILC packet header to have the first two bytes
1540 (the packet length) encrypted. Affected files aroung the
1541 code tree, lib/silccore/silcpacket.[ch]. Removed the
1542 SilcPacketCheckDecrypt callback. It is not needed anymore
1543 since the silc_packet_receive_process will determine now
1544 whether the packet is normal or special.
1546 * Implemented the unidirectional MAC keys. Affected files
1547 lib/silcske/silcske.c, silcd/protocol.c and
1548 lib/silcclient/protocol.c.
1550 * Implemented the packet sequence number to the MAC computation.
1551 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1552 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1553 lib/silcclient/protocol.c.
1555 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Allow backup router to announce servers. All servers
1558 announced by backup router are added to the global list
1559 automatically. Update hte server's socket to our primary
1560 router also when backup router announces a server.
1561 Affected file silcd/packet_receive.c.
1563 * Do not update the client->router in the function
1564 silc_server_udpate_clients_by_server if the client is on
1565 global list. We might fail to find any specific server
1566 for locally connected clients and local cell clients. They
1567 should still use the `from' and not `to' as client->router.
1568 This fixes backup router resuming protocol. Affected file
1569 silcd/server_util.c.
1571 * Decrease channel statistics count only if the channel
1572 deletion worked. Affected files are silcd/server.c and
1573 silcd/server_util.c.
1575 * Added silc_server_update_servers_by_server to update origin
1576 of all server entries. Used during backup router protocol.
1577 Affected files silcd/server_util.[ch], silcd/server.c. and
1578 silcd/backup_router.c.
1580 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1581 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1582 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1583 lib/silccrypt/silchmac.c.
1585 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Assure that router cannot reroute the same channel message
1588 to the sender. Affected file silcd/packet_receive.c.
1590 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Made better checks that the channel message is not sent
1593 to the router it came from. Affected file is
1594 silcd/packet_send.c. Fixed memory leak too.
1596 * Announce informations for incoming router connection, but
1597 only after checking if it is replaced by backup router.
1598 Affected file silcd/packet_receive.c.
1600 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Fixed the backup resuming protocol to work in multiple
1603 router environment. Affected file silcd/server_backup.c.
1605 * Route packet only to one router in the function
1606 silc_server_packet_send_to_channel. Affected file is
1607 silcd/packet_send.c.
1609 * Fixed silc_server_send_notify_dest to set the broadcast
1610 flag. Fixed the silc_server_send_notify_topic to actually
1611 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1612 Affected file silcd/packet_send.c.
1614 * Changed the SFTP Filesystem interface. Changed the
1615 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1616 the filesystem operation function. The SilcSFTPFilesystem
1617 is now a context that is allocated by all filesystem allocation
1618 functions and it already includes the operations structure
1619 and filesystem specific context. It is given as argument
1620 now to the silc_sftp_server_start. This made the interface
1621 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1622 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1624 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Changed the backup router adding and getting interfaces
1627 in the server. The router that will be replaced by the
1628 specified backup router is now sent as argument. Affected
1629 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1632 * Added silc_net_addr2bin_ne to return the binary form of
1633 the IP address in network byte order. Affected files

1636 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Check for existing server ID in silc_server_new_server
1639 and in silc_server_connect_to_router_final and remove the
1640 old entry if it exists. Affected file silcd/packet_receive.c,
1643 * Send the channel message always to only one router, either
1644 in upstream or downstream. Affected file is
1645 silcd/packet_send.c.
1647 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Wrote the definition of the backup resuming protocol to the
1650 protocol specification.
1652 * Removed one redundant channel key generation from normal
1653 server during joining procedure. Removed one redundant
1654 channel key sending from server to router during joining
1655 procedure. Affected file silcd/command.c.
1657 * Made minor bugfixes to the backup router resuming protocol.
1658 Affected file silcd/server_backup.c, server.c.
1660 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Added --disable-asm configuration option. Affected files
1663 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1666 * Implemented the backup resuming protocol that is used to
1667 resume the primary router position in the cell after the
1668 primary router comes back online. Affected files
1669 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1670 and silcd/server_util.[ch].
1672 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Sleep two (2) seconds after sending QUIT command to server.
1675 Affected file lib/silcclient/command.c.
1677 * Assure that if outgoing data buffer is pending do not force
1678 send any data. Affected file silcd/packet_send.c.
1680 * Assure that if outgoing data buffer is pending do not force
1681 send any data. Affected file lib/silcclient/client.c.
1683 * Implemented the backup router support when the primary router
1684 goes down. The servers and routers can now use the backup
1685 router as new primary router without loosing connectivity.
1687 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1690 in the server to indicate disabled entry. All data read
1691 from the connection will be ignored and no data is sent
1692 for entry that is disabled. Affected files are
1693 silcd/idlist.h, silcd/server.c.
1695 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Created SFTP client and server test programs in the
1698 lib/silcsftp/tests directory.
1700 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Implemented memory filesystem (virtual filesystem) for
1703 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1706 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Implemented the SFTP (SSH File Transfer Protocol) to the
1709 lib/silcsftp. It includes SFTP client and SFTP server
1712 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Moved lib/silccore/silcprotocol.[ch] to the
1715 lib/silcutil library.
1717 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1718 take variable argument list pointer as argument. Affected
1719 file lib/silcutil/silcbuffmt.[ch].
1721 * Added silc_buffer_set function that is used to set data
1722 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1723 Affected file lib/silcutil/silcbuffer.h.
1725 * Changed various routines in the core library to use the new
1726 silc_buffer_set instead of allocating new buffer only for
1729 * Added 64-bit value formatting and unformatting support to the
1730 silc_buffer_[un]format routines. Affected file is
1731 lib/silcutil/silcbuffmt.[ch].
1733 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1734 to includes/bitmove.h.
1736 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed channel user mode saving in client library. Affected
1739 file lib/silcclient/command[_reply].c.
1741 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Defined the file transfer to the SILC Protocol. Added
1744 new packet type SILC_PACKET_FTP and defined File Transfer
1745 Payload. The mandatory file transfer protocol is SFTP
1746 (SSH File Transfer Protocol). Affected file in addition
1747 of the internet draft is lib/silccore/silcpacket.h.
1749 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1750 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1751 is used as part of backup router protocol when the primary
1752 router of the cell is back online and wishes to resume
1753 the position as primary router.
1755 * Redefined the MAC generation keys in the protocol. The
1756 same key is not used anymore in both direction. Both
1757 direction will now use different keys for sending and
1758 receiving. This fixes a potential security flaw. This
1759 change causes incompatibilities in the protocol.
1761 * Redefined also the MAC computation from the packet.
1762 An packet sequence number is now added to the MAC
1763 computation. This prevents possible replay attacks against
1764 the protocol. This change too causes incompatibilities
1767 Added `sequence' field to the SilcPacketContext to hold
1768 the current sequence number for the packet.
1770 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Added `created' field to the SilcIDListData in the file
1773 silcd/idlist.h to indicate the time when the entry was
1776 * Added `created' field to the SilcChannelEntry too. Affected
1777 file silcd/idlist.h.
1779 * Added `creation_time' aguments to all the announcement functions
1780 in the server. If it is provided then only the entries that
1781 was created after the provided time frame are actually
1782 announced. Affected file silcd/server.[ch].
1784 * The protocol says that the Channel ID's IP address must be
1785 based on the router's IP address. Added check for this in
1786 the silc_server_new_channel when processing incoming New Channel
1787 Payload. Affected file silcd/packet_receive.c.
1789 * Print out the correct version with --version in SILC client.
1790 Affected file irssi/src/silc/core/silc-core.c.
1792 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Fixed WHOWAS command to check for completnes of the client
1795 entry always, not just when the command is coming from client.
1796 Affected file silcd/command.c.
1798 * Added new function silc_server_packet_queue_purge to purge the
1799 outgoing data queue to the network. After the function returns
1800 it is guaranteed that the outgoing packet queue is empty.
1801 Affected file silcd/packet_send.[ch].
1803 * Purge the outgoing packet queue in the rekey protocol's final
1804 callback to assure that all rekey packets go to the network
1805 before quitting the protocol. Affected file silcd/server.c.
1807 * Added silc_client_packet_queue_parse as similar function as
1808 in server to the client library. The affected file is
1809 lib/silcclient/client.c.
1811 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Splitted silcd/server.c and created silcd/server_util.[ch]
1814 for utility functions.
1816 * Added new socket flag SILC_SF_DISABLED to indicate that the
1817 connection is open but nothing can be sent to or received from
1818 the connection. Affected file lib/silcutil/silsockconn.[ch].
1819 The checking for disabled socket is checked in the low level
1820 silc_socket_write and silc_socket_read functions.
1822 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Allow only nicknames and channel names that fits into the
1825 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1827 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * When processing JOIN command reply in server check that if
1830 the channel exists in our global list we'll move it the local
1831 list. Affected file silcd/command_reply.c.
1833 * Fixed the check whether client is joined on the channel already
1834 in JOIN command. Affected file lib/silcclient/command.c.
1836 * Fixed the JOIN command reply to check whether the channel
1837 already exists. Affected file lib/silcclient/command_reply.c.
1839 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Added silc_ske_status_string to map the SKE error numbers
1842 to readable strings. The affected files are
1843 lib/silcske/silcske[_status].[ch].
1845 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Do not show the private channels on the WHOIS channel list
1848 as it is not allowed by the protocol. The affected file is
1851 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Assure that the packet length digged from the actual packet
1854 is something sensible in the silc_packet_decrypt_rest_special
1855 in lib/silccrypt/silcpacket.c.
1857 * Free and NULL the allocated pointer in silc_hmac_alloc if
1858 the HMAC allocation fails. The affected file is
1859 lib/silccrypt/silchmac.c.
1861 * Print the selected security properties to the log files in
1862 the server. Affected file silcd/protocol.c.
1864 * Add SKE's reference counter even if calling the completion
1865 callback manually. Otherwise it goes negative, although it
1866 does not cause any problems. The affected file is
1867 lib/silcske/silcske.c.
1869 * Remove the client entry with short timeout after giving the
1870 KILL command. Affected file lib/silcclient/command.c.
1872 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1873 case all found clients are already disconnected (WHOWAS would
1874 found them) in the server. Affected file silcd/command.c.
1876 * Update the last_receive (time of last data received) to be
1877 updated only when received private or channel message so that
1878 the idle time showed in WHOIS makes more sense.
1880 * Added boolean field `valid' in to the SilcClientEntry in the
1881 client library to indicate whether the entry is valid or not.
1882 This fixes the nickname change bug on channel when changing
1883 the nickname to be same than the old (like nick to Nick) the
1884 nickname formatter doesn't set the new nick anymore to Nick@host.
1885 Affected file lib/silcclient/idlist.[ch].
1887 * Now actually fixed the nickname changing on disconnection.
1888 Added new function silc_change_nick to the Irssi SILC Client.
1889 Affected file irssi/src/silc/core/client_ops.c,
1890 irssi/src/silc/core/silc-nicklist.[ch].
1892 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Check that the public key exists in the GETKEY command before
1895 trying to encode it. Affected file silcd/command.c.
1897 * Print some notifications on received public keys with GETKEY
1898 command in the Irssi SILC Client. Affected files are
1899 irssi/src/fe-common/silc/module-formats.[ch],
1900 irssi/src/silc/core/client_ops.c.
1902 * Use IDENTIFY command to resolve the server information in the
1903 GETKEY command instead of INFO command. Affected file
1904 lib/silcclient/command.c.
1906 * All command reply functions in the client library now calls
1907 the pending command reply callbacks even if an error has
1908 occurred. The server has done this a long time and now it was
1909 time to move the client library to this as well. Now all
1910 errors can be delivered back to the pending command reply
1911 callbacks if necessary. Affected files are
1912 lib/silcclient/command[_reply].[ch].
1914 * Change the nickname on disconnection back to the username
1915 because in reconnect the server will enforce it to it anyway.
1916 Affected file irssi/src/silc/core/silc-servers.c.
1918 * Fixed a config file parsing bug in the Irssi SILC client.
1919 Affected file irssi/src/silc/core/clientconfig.c.
1921 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * When printing the channel mode on JOIN, verify that the
1924 channel key and channel's HMAC are valid. Affected file
1925 irssi/src/silc/core/client_ops.c.
1927 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1930 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1931 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1933 * Removed channel key rekey task deleting from the function
1934 silc_server_save_channel_key. Affected file silcd/server.c.
1935 Added explicit timeout task context instead that is used to
1936 delete the task if we are registering a new task before the
1937 new task has elapsed.
1939 * When channel key rekey occurs the client library now saves
1940 the old channel key for a short period of time (10 seconds) and
1941 is able to use it in case some is still sending channel
1942 messages encrypted with the old key after the rekey. Affected
1943 file lib/silcclient/[idlist.h|client_channel.c].
1945 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Added check to the silc_server_new_id_real to not accept
1948 new ID if it is the sender's own ID. Affected file is
1949 silcd/packet_receive.c.
1951 * Assure that we do not announce ourself or the one we've
1952 sending our announcements when we're router and are announcing
1953 servers to our primary router. Affected file silcd/server.c.
1955 * Fixed silc_server_command_identify_check_client to assemble
1956 correct WHOIS packet. It send corrupted WHOIS packet and
1957 caused problem with router to router connections. Affected
1958 file silcd/command.c.
1960 Fixed also silc_server_command_whois_check the same way
1961 as for the IDENTIFY command.
1963 * Added new SilcIDListStatus to the server in the SilcIDListData
1964 structure. The status now includes the current status of
1965 the entry (like registered, resolved etc.). Affected file
1966 silcd/idlist.[ch]. Defined a bunch of different status types
1967 as well. This replaced the old boolean registered field as well.
1969 Added resolve_cmd_ident field to the SilcClientEntry structure
1970 too so that if the entry is for example being resolved so
1971 another command may attach to the same pending command reply
1972 without requiring to resolve the same entry again. This concept
1973 should optimize the WHOIS and the IDENTIFY resolving under
1974 heavy load by taking away unnecessary resolving for entries
1975 that are being resolved already.
1977 Added support for adding multiple pending commands for one
1978 command idenfier. Affected file silcd/command[_reply].[ch].
1980 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1981 before deleting the data. Otherwise the hash table will have
1982 freed data in comparison functions. Affected file is
1983 silcd/command_reply.c.
1985 * Fixed silc_idlist_replace_client_id to add the new entry to
1986 the cache with NULL nickname. Otherwise there will be invalid
1987 memory as the nickname after the nickname is freed. Affected
1988 file silcd/packet_receive.c.
1990 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1991 saved into wrong slots because the previous number of entries
1992 was not taken into account. Affected file silcd/idlist.c.
1993 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1995 * If we are router and we receive JOIN notify to a channel that
1996 does not have any users then notified client is marked as the
1997 channel founder, as it is it. The affected file is
1998 silcd/packet_receive.c
2000 * Added to the extended hash table API's table_del_*ext functions
2001 the destructor as argument too, so that the caller can decide
2002 which destructor to use or whether to use destructor at all.
2003 Affected file lib/silcutil/silchashtable.[ch].
2005 * Fixed ID Cache purging. It actually deleted the entries from
2006 the hash table after the data was freed. The hash table ended
2007 up comparing freed memory. The affected file is
2008 lib/silccore/silcidcache.c.
2010 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Fixed Irssi SILC client's KILL command's HELP syntax.
2014 * The USERS command now resolves the detailed user information
2015 if the userinfo field is missing. Affected file is
2016 lib/silcclient/command_reply.c.
2018 * Do not print error in silc_file_read if the read file does
2019 not exist. Just silently return NULL. Affected file is
2020 lib/silcutil/silcutil.c.
2022 * Fixed the silc_log_output to not wine about NULL filename
2023 and to not create some bogus " " filename. Affected file is
2024 lib/silcutil/silclog.c.
2026 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Fixed various printing bugs on the user interface in the
2029 Irssi SILC Client. Minor changes that were forgotten from
2032 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Fixed the configure.in.pre and the compilation and distribution
2035 environment to support the new autoconf 2.52. That version is
2036 now required to compile the CVS trunk.
2038 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2041 to generally parse user@fqdn format strings. Affected file
2042 lib/silcutil/silcutil.c.
2044 * Added nickname_format and nickname_force_format fields to the
2045 SilcClientParams structure. The first one defines the format
2046 for the nicknames that the library will enforce if the receives
2047 multiple same nicknames. The second one is boolean value and
2048 can be used to force the library to always enforce the format
2049 to the nicknames regardles whether there are multiple nicknames
2050 or not. This configurable formatting was employed to flexibly
2051 support accessing multiple nicknames from the user interface.
2052 The userinterface can now set the nicknames to what ever format
2053 they prefer. Affected file lib/silcclient/silcapi.h.
2055 Added function silc_client_nickname_format to the file
2056 lib/silcclient/idlist.c. It performs the nickname formatting.
2058 Added new field `hostname´ to the SilcClientEntry context.
2059 It holds the hostname of the client. Affected file is
2060 lib/silcclient/idlist.h.
2062 * Irssi SILC Client sets the nicknames in nick@hostn format.
2063 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2064 irssi/src/silc/core/silc-core.c.
2066 The WHOIS printing now also shows both the real nickname and
2067 the formatted nickname so that user knows how to access the
2068 user if there are multiple same nicknames cached. Affected
2069 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2070 printing formatting too to take the hostname now as a separate
2071 argument. The Affected file is
2072 irssi/src/fe-common/silc/modules-formats.[ch].
2074 * Changed the silc_client_get_clients_local to accept the formatted
2075 nickname as argument. It accepts the real nickname too but the
2076 formatted nickname can be used to find the true entry from
2077 multiple entries. Affected file lib/silcclient/silcapi.h and
2078 lib/silcclient/idlist.c.
2080 * Added nickname_format_parse field to the SilcClientParams.
2081 It is a callback function provided by the application to parse
2082 the nickname out of the formatted nickname string. The library
2083 calls it to get the nickname from the formatted string. Since
2084 the application generally knows better the format of the nickname
2085 string it parses it instead of the library, even though library
2086 encodes the formatted string. If the callback function is not
2087 provided then the library will use the string as is. The
2088 affected file is lib/silcclient/silcapi.h.
2090 * All the nickname strings passed to the client library in
2091 commands are now expected to be formatted nickname strings.
2092 If the command does not support the formatted nickname string
2093 it will assume that the sent string is the actual nickname.
2094 Affected file lib/silcclient/command.c.
2096 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Added public key authentication support to OPER and SILCOPER
2099 commands in the client library. Affected file is
2100 lib/silcclient/command.c.
2102 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Changed the get_auth_methdod client operation to be asynchronous.
2105 It can be async if the application resolves the authentication
2106 method from the server during the negotiation. Added new
2107 SilcGetAuthMeth completion callback that the application will
2108 call after resolving the authentication method.
2110 Added function silc_client_request_authentication_method that
2111 the application can use to resolve the authentication method
2112 from the server. Added also SilcConnectionAuthRequest callback
2113 that the library will call after the server has replied. The
2114 application can call this function if it does not know the
2115 current authentication method.
2117 Affected files are lib/silcclient/client.c and
2118 lib/silcclient/silcapi.h.
2120 * The Irssi SILC client now automatically resolves the authentication
2121 method incase any configuration information is not present (and
2122 currently there never is). The affected file is
2123 irssi/src/silc/core/client_ops.c.
2125 * Fixed public key authentication from the client library.
2126 Affected file lib/silcclient/protocol.c. Changed also the
2127 protocol specification about the public key authentication in
2128 the connection authentication protocol. The actual data to be
2129 signed is now computed with a hash function before signing.
2131 * Fixed the public key authentication from the server as well.
2132 Affected file silcd/protocol.c.
2134 * Removed the mlock()'s from the memory allocation routines.
2135 Affected file lib/silcutil/silcmemory.c. The ./configure does
2136 not check anymore for the mlock(). Affected file is
2139 * Fixed USERS command in server to allow the execution of the
2140 command for private and secret channels if the client sending
2141 the command is on the channel. Affected file silcd/command.c.
2143 * Fixed silc_client_get_clients_local to return the clients
2144 count correctly. It could return wrong value. Affected file
2145 lib/silcclient/idlist.c.
2147 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2150 types. The assembler optimizations seemed not to like 64-bit
2151 data types. The assmebler optimizations thus are now enabled
2152 also for BSD systems as opposed to only enable them for Linux.
2154 * Do not check for threads at all on BSD systems. Affected
2155 file configure.in.pre.
2157 * Removed -n and -h options from the Irssi SILC Client since
2158 they are not used in silc.
2160 * Fixed the prime generation to assure that the first digit
2161 of the generated random number is not zero since our conversion
2162 routines does not like number strings that starts with zero
2163 digit. If zero digit is seen the random number is regenerated.
2164 This caused some corrupted RSA keys when the zero first digit
2165 was met. Affected file lib/silcmath/silcprimegen.c.
2167 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Fixed WIN32 configuration in the ./configure script.
2170 Fixed to include xti.h on environments that has it.
2171 Patches by Carsten Ilchmann and andrew.
2173 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Changed the silc_id_create_client_id to be collision
2176 resistant. It is now assured that there cannot be created
2177 two same client ID's. I suspect that some weird bugs in
2178 the server were actually caused by duplicate Client IDs.
2179 Affected file silcd/serverid.[ch]. A router receiving
2180 new ID now also assures and informs the sending server
2181 if the ID caused collision.
2183 * Changed the silc_id_create_channel_id to also assure that
2184 there are no collisions.
2186 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Statement about ignoring the Mutual Authentication flag when
2189 performing rekey with PFS was a bit misleading. It is ignored
2190 if it was set in the initial negotiation, it cannot be even
2191 set in the rekey. Fixed in the ke-auth draft. Started the
2192 new versions of the protocol drafts in the doc/.
2194 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Fixed a bug in silc_client_command_identify_save when saving
2197 new channel information. The channel name was no duplicated
2198 and caused crash on exit. Affected file is
2199 lib/silcclient/command_reply.c.
2201 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed the getkey command handling in the server. Send just
2204 empty OK reply to the sender if the key could not be fetched
2205 (but everything else was ok, like the key just was not available).
2206 Changed the public key parameter to optional in the protocol
2207 specs so that empty OK reply can be sent. Affected file
2210 Added a message to Irssi SILC client to tell to user if the
2211 server did not return a public key.
2213 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Fixed a channel key regeneration bug. It registered new
2216 timeout tasks exponentially until all system resources were
2217 used. Affected file silcd/server.c.
2219 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Added the SILC Document generator to the scripts/silcdoc.
2222 It can be used to generate the Toolkit Reference Manual out
2223 of the source tree. Internally it will also use the RoboDoc
2224 generator now imported in util/robodoc.
2226 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Added couple of return's in rekey protocol if error orccurred
2229 during the protocol. The execution must be terminated.
2230 Affected file silcd/protocol.c. Also, terminate the protocol
2231 always with timeout.
2233 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * The client's Client ID was created initally from the wrong
2236 nickname (it could have been in format nick@host) in the
2237 silc_server_new_client. Affected file silcd/packet_receive.c
2239 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Added some SILC_LOG_ERROR's to various error conditions
2242 if client could not be added to ID cache. Affected files
2243 silcd/packet_receive.c and silcd/server.c.
2245 * When client's sock->user_data is freed, NULL also the
2246 client->router and client->connection pointers. Added check
2247 for these pointers being NULL to various places around the
2248 code. Affected file silcd/server.c.
2250 * Added client->data.registered == TRUE checks to various
2251 places around the code to assure that unregistered client's
2252 are not handled when it is not allowed. Affected file
2255 * Added `bool registered' fields to all
2256 silc_idlist_[server|client]_get_* routines to indicate whether
2257 the fetched client needs to be registered or not. Affected
2258 file silcd/idlist.[ch].
2260 * Add your own entry as registered to the ID cache in the
2261 server. Affected file server.c.
2263 * Fixed a bug in silc_server_new_server. The SilcServer was
2264 set as the new server's context instead of SilcServerEntry.
2265 This naturally caused some weird bugs.
2267 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Do not delete the channel rekey task when adding it
2270 for in silc_server_create_channel_key.
2272 * Changed the silc_server_create_channel_key to return
2273 TRUE or FALSE to indicate the success of the channel key
2276 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Fixed MSVC++ project files and added missing files to
2279 Makefiles under win32/.
2281 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Do not add TCP_NODELAY flag if the operating system
2284 does not have it defined. Affected files are
2285 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2287 * Fixed buffer overflow from Irssi SILC Client. Affected
2288 file irssi/src/fe-common/core/themes.c.
2290 * Fixed double free in client library in the file
2291 lib/silcclient/client.c when disconnecting from server.
2293 * Applied double free patch from cras to Irssi SILC client.
2294 Affected files irssi/src/core/[modules/expandos].c
2296 * Fixed the disconnection handling to Irssi SILC Client.
2297 The application must call silc_client_close_connection
2298 in ops->connect client operation in case of failure of
2299 the connection. Affected file is
2300 irssi/src/silc/core/client_ops.c.
2302 * Do not set sock->protocol to NULL in the function
2303 silc_client_close_connection after executing the protocol's
2304 final callback since the sock might not be valid anymore.
2305 Affected file lib/silcclient/client.c.
2307 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Do not enable SILC_THREADS if the linking with libpthread
2310 did not happen. Affected file configure.in.pre.
2312 * Added notion to protocol specification that server must
2313 verify the sent authentication payload with CMODE when
2314 setting the channel founder key. Implemented it to the
2315 server. Affected file silcd/command.c.
2317 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Added _EXTRA_DIST SILC distribution variable to the
2320 distributions file. It is used to conditionally add extra
2321 files or directories to the specific distribution. Affected
2322 files ./prepare, Makefile.am.pre and distributions.
2324 Removed the `_' from the start of the distribution names.
2327 * Added README.WIN32 for instructions to compile the Toolkit
2330 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Fixed a double free in disconnection in the server. Affected
2333 file is silcd/server.c.
2335 * Fixed the lib/silcske/groups.c to work now also with GMP
2336 MP library. The string conversion did not work when using
2337 specific base and the base is indicated in the string as well.
2339 * Created win32/ directory which now includes MSVC++ specific
2340 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2341 It will appear only in the toolkit distribution
2343 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Changed the key material distribution function in case when
2346 the hash output is too short. The data is now concatenated
2347 a bit differently than it used to. Made the change to the
2348 SKE protocol specification.
2350 * Added better GMP detection to configure.in.pre. A patch
2353 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Fixed a minor bug in SKE that might cause some problem on
2356 some platforms. Affected file lib/silcske/silcske.c.
2358 * Added the cookie checking for initiator in the SKE. It checks
2359 that the responder returns the sent cookie unmodified. The
2360 affected file is lib/silcske/silcske.c. Added new SKE
2361 error type INVALID_COOKIE that can be sent during the
2362 negotiation. Fixed some memory leaks as well.
2364 * Added the "invalid cookie" error message to Irssi SILC client's
2367 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Added `task_max' field to the SilcClientParams to indicate
2370 the maximum tasks the scheduler can handle. If set to zero,
2371 default values are used. Affected file lib/silcclient/silcapi.h.
2373 * Fixed memory leaks in silc_client_close_connection. Affected
2374 file lib/silcclient/client.c.
2376 * Added silc_client_del_client_entry to client library to free
2377 all memory of given client entry. Affected file is
2378 lib/silcclient/idlist.[ch].
2380 * Added new functions silc_client_del_channel and
2381 silc_client_del_server to delete channel and server entries.
2382 Affected file lib/silcclient/[silcapi.h/idlist.c].
2384 * Removed silc_client_del_client_by_id from silcapi.h.
2386 * Fixed the INFO command to return the server's own info
2387 correctly when querying by Server ID. Affected file is
2390 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Removed the non-blocking settings in WIN32 code in the
2393 silc_sock_[read/write] and added SleepEx instead. Affected
2394 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2395 of input data is now checked with FIONREAD and ioctlsocket.
2397 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Call silc_schedule_task_del_by_context in the
2400 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2401 Affected file lib/silccore/silcprotocol.c.
2403 * Call silc_protocol_cancel for active protocols in the
2404 silc_server_close_connection if the funtion
2405 silc_server_free_sock_user_data has not been called.
2406 Affected file silcd/server.c.
2408 * Generic tasks cannot be deleted using the del_by_fd
2409 task deleting function since generic tasks does not match
2410 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2412 * Added a notion to SILCOPER help file that the SILCOPER works
2413 only on router server, not on normal server.
2415 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Added for WIN32 support for the new scheduler as well.
2418 Affected file lib/silcutil/win32/silcwin32schedule.c.
2420 * Fixed the SHA1 implementation to work on various platforms.
2422 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2425 API. It is part of the scheduler now. Everything else is
2426 as previously but some functions has changed their names.
2427 Checkout the lib/silcutil/silcschedule.h for the interface.
2428 Updated all applications to use the new interface. Affected
2429 files are lib/silcutil/silcschedule.[ch].
2431 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Found a bug in the SKE implementation. The HASH value,
2434 specified by the protocol, was not computed correctly. The
2435 public key of the responder was not added to the computation
2436 even though it is mandatory. Affected file lib/silcske/silcske.c.
2437 This unfortunately causes incompatibilities with older
2438 clients and servers.
2440 * Added WIN32 specific network init and uninit functions:
2441 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2442 the Winsock2. Affected file lib/silcutil/silcnet.h and
2443 lib/silcutil/win32/silcwin32net.c.
2445 * Set the socket always to nonblocking mode on WIN32 after
2446 reading data or writing data. Affected file is
2447 lib/silcutil/win32/silcwin32sockconn.c.
2449 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Fixed various compilation problems under WIN32. Affected
2452 files lib/silcutil/win32/silcwin32thread.c and
2453 lib/silcutil/win32/silcwin32schedule.c.
2455 * Removed all _internal.h #includes from public header
2456 files. Internal headers must never be included from
2459 Removed also the lib/silcske/payload_internal.h file.
2461 * All include files that may be needed (public and some others
2462 included by the public headers) by application developers are
2463 now copied to the ./includes directory. It does not copy any
2464 internal headers. Affected file Makefile.defines.pre and all
2465 Makefile.am's under lib/ and subdirs.
2467 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Do not change the ~/.silc directory's permissions automatically.
2470 Affected file irssi/src/silc/core/clientutil.c.
2472 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Do not cancel the protocol in silc_server_close_connection
2475 it might cause recursion. Now cancelled in the function
2476 silc_server_free_sock_user_data. Affected file silcd/server.c.
2478 * Fixed the silc_server_remove_clients_by_server to regenerate
2479 the channel keys correctly finally. Added also new function
2480 silc_server_remove_clients_channels to actually do it.
2481 Affected file silcd/server.c.
2483 * Fixed the silc_server_new_channel to not crash by giving
2484 wrong router to the new channel. Affected file is
2485 silcd/packet_receive.c.
2487 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2490 which is given as argument to the silc_client_alloc now.
2491 It can be used to configure the client and set various parameters
2492 that affect the function of the client.
2494 * The USERS command in server did not check whether the channel
2495 is private or secret. Affected file silcd/command.c.
2497 * Added new argument to the USERS command in protocol specification.
2498 The USERS command now can take the channel name as argument
2499 as well. Added support for this in client and server and
2500 updated the protocol specs.
2502 * Completed the GETKEY command in client. It can be now used
2503 to fetch also servers public key not only some clients.
2504 Affected files lib/silcclient/command[_reply].c.
2506 * Added silc_client_get_server to return server entry by the
2507 server name. Affected files lib/silcclient/silcapi.h and
2510 * Redefined the IDENTIFY command in protocol specification to be
2511 more generic. It now can be used to query information about
2512 any entity in the SILC Network, including clients, servers and
2513 channels. The query may be based either the entity's name
2514 or the ID. Added support for this in both client and server.
2516 Affected files silcd/command.c and lib/silcclient/command.c
2517 and command_reply.c.
2519 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2520 the _from_client and _from_server functions. Affected file
2523 * Added silc_client_get_channel_by_id_resolve to the file
2524 lib/silcclient/silcapi.h to resolve channel information by
2525 its ID. Added also silc_client_get_channel_by_id that
2526 does not resolve it from the server.
2528 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Added SilcServerEntry context into the client library
2531 to represent one server. The INFO command now allocates
2532 these to save the resolved server info. For now on the
2533 client library will also keep information about servers,
2534 connected and resolved with INFO.
2536 The INFO command now allocates the SilcServerEntry context
2537 and saves the server info there. The COMMAND_REPLY in
2538 the INFO now returns the parameters to application in
2539 same order as defined in the protocol specification.
2541 The entries are cached in the client->server_cache.
2543 * The INFO command is now issued after received the Client ID
2544 from the server. Affected file lib/silcclient/client.c.
2546 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2547 to the application as the mode changer might be server.
2548 It is guaranteed that NULL is not returned anymore to the
2549 application. Affected file lib/silcclient/client_notify.c.
2551 The ID Type is now also passed to the application so that
2552 it can check whether the returned entry is SilcClientEntry
2555 Added new function silc_client_get_server_by_id to return
2556 the server entry by ID. Affected files are the
2557 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2559 * Do not create the channel in the Irssi SILC Client when issuing
2560 the JOIN command but when received the sucessful JOIN command
2561 reply. Otherwise the channel might get created even though we
2562 could not join it. The Affected file is
2563 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2565 * Fixed a channel joining bug in router. The router must also
2566 check the channel modes, invite and ban lists etc. when serving
2567 the JOIN command sent by normal server. Affected file is
2568 silcd/command.c. The router now resolves the client's
2569 information from the server who sent the JOIN command if it
2570 does not know it, and processes the JOIN command only after
2573 * Changed the SilcCommandCb to take new argument; void *context2.
2574 Affected file lib/silccore/silccommand.h
2576 The second argument in the command callbacks in the server now
2577 includes the SilcServerCommandReplyContext if the command was
2578 called as pending command callback from the command reply.
2579 Otherwise it is NULL. When called as pending the status of the
2580 command reply will be checked and if it was erronous the
2581 error will be sent to the original sender of the command.
2582 This way the client always receives the error messages even
2583 though the server was actually the one who received the error
2584 when it resent the command to router, for example. Affected
2585 files silcd/command[_reply].[ch].
2587 * Fixed sending WHOWAS command's error message to client if
2588 the requested client could not be found. It was missing.
2591 * Changed the CMODE and CUMODE commands reply arguments in the
2592 protocol specification. The Channel ID is now sent in both
2593 of the commands to identify the channel. Implemented this
2594 new feature to the client and server. Affected files
2595 lib/silcclient/command_reply.c and silcd/command.c.
2597 * Made better checks for invite and ban lists in the JOIN
2598 command in server. Affected file silcd/command.c.
2600 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2602 * The server now performs the incoming host IP/DNS lookup
2603 using the silc_socket_host_lookup and thus does not block
2604 the server anymore. Affected file silcd/server.c.
2606 * Completed the multi-thread support for SILC Scheduler in
2607 the lib/silcutil/silcschedule.c.
2609 * Fixed the configure.in.pre to detect the pthread correctly
2612 * Fixed a deadlock in silc_task_queue_wakeup in the file
2613 lib/silcutil/silctask.c.
2615 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Added new function silc_schedule_wakeup that is used in
2618 multi-threaded environment to wakeup the main thread's
2619 schduler. It needs to be used when a thread adds a new task
2620 or removes a task from task queues. After waking up, the
2621 scheduler will detect the task queue changes. If threads
2622 support is not compiled in this function has no effect.
2623 Implemented the wakeup mechanism to both Unix and WIN32
2624 systems. Affected files are lib/silcutil/silcschedule.[ch],
2625 lib/silcutil/unix/silcunixschedule.c and the
2626 lib/silcutil/win32/silcwin32schedule.c.
2628 * Added new function silc_task_queue_wakeup to wakeup the
2629 scheduler by the specified task queue. Affected file
2630 lib/silcutil/silctask.[ch].
2632 * The silc_socket_host_lookup_start now wakes up the scheduler
2633 after adding the timeout task. Affected file is
2634 lib/silcutil/silcsockconn.c.
2636 * The silc_socket_host_lookup is synchronous now if the threads
2637 support is not compiled in. However, the callback is still
2638 called asyncronously through the scheduler, anyway. Affected
2639 file lib/silcutil/silcsockconn.c.
2641 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Added new function silc_socket_host_lookup to perform
2644 asynchronous IP and FQDN lookups for the socket connection.
2645 Affected files lib/silcutil/silcsockconn.[ch].
2647 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2650 that may or may not compile the mutex support in.
2652 Changed the silc_mutex_alloc interface. It allocates the
2653 mutex now to the sent pointer and returns TRUE or FALSE.
2655 Affected file lib/silcutil/silcmutex.h.
2657 * Wrote the SILC Task Queue interface to support multi-threads.
2658 Affected file lib/silcutil/silctask.[ch].
2660 * Wrote the SILC Scheduler to support multi-threads. Affected
2661 file lib/silcutil/silcschedule.c.
2663 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2666 in lib/silcutil/win32/.
2668 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Defined SILC Mutex API and SILC Thread API and implemented
2671 them for Unix. Affected files are
2672 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2673 lib/silcutil/unix/silcunixmutex.c and
2674 lib/silcutil/unix/silcunixthread.c.
2676 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed the silc_server_remove_clients_by_server's channel
2679 key re-generation. The hash table handling was incorrect
2680 and would not work with many channels. Affected file is
2683 * Fixed some memory leaks around the server code.
2685 * Rewrote the silc_server_get_users_on_channel to support IPv6
2686 based Client ID's. Affected file silcd/server.c.
2688 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2689 specification. However, a separate document must be written
2690 to define the detailed signing procedure and the payload
2691 associated with the flag. Defined the flag to the
2692 lib/silccore/silcchannel.h as well.
2694 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Changed the dynamic tables to static size tables in the
2697 lib/silccrypt/silchmac.c.
2699 * Removed GCC dependencies from the code. A patch by cras.
2701 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Do not show the error "Error receiving packet bla bla"
2704 in server if it really was not an error (-2 means that reading
2705 is pending). Affected file silcd/server.c.
2707 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Fixed a possible crash in silc_server_remove_clients_by_server
2710 in silcd/server.c. Fixed there also some memory leaks.
2712 * Fixed the silc_idlist_replace_client_id. It could replace
2713 wrong key in the hash table. Affected file silcd/idlist.c.
2715 * Do not check whether there are global users on the channel
2716 if the channel->global_users is FALSE. Affected functions
2717 silc_server_remove_from_one_channel and
2718 silc_server_remove_from_channels in silcd/server.c. Also,
2719 do not check if the removed client is local as we can be
2720 sure that global client was not removed from the channel
2721 and checking for global users is not needed.
2723 * The silc_server_remove_clients_by_server now re-generates
2724 the channel keys correctly for those channels that had
2725 clients removed from them. Affected file silcd/server.c.
2727 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Found the reason of random crashes in the server. We weren't
2730 ignoring the SIGPIPE signal (which can be sent in write())
2731 and it crashed the server. Affected file silcd/silcd.c.
2733 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Assure that sock->user_data is not NULL in the function
2736 silc_server_packet_send in silcd/packet_send.c.
2738 * Disconnect the remote connection if it could not be added
2739 to any ID lists in the server. The affected file is
2742 * Check in silc_server_packet_send[_real/dest] that the
2743 socket is not disconnecting and ignore the data if it is.
2744 Affected file silcd/packet_send.c.
2746 * Define inline to __inline on native WIN32 compilation.
2747 Affected file includes/silcwin32.h.
2749 * Added some explicit type casts for inline code since MSVC
2750 require them. Affected files lib/silcutil/silcbuffer.h,
2751 lib/trq/silcdlist.h and lib/trq/silclist.h.
2753 * Print warning in log files from now on if the packet
2754 decryption fails. Affected file silcd/server.c.
2756 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Changed the `say' client operation's interface to accept
2759 new `type' argument to indicate the type of the message sent
2760 by the library. The application may filter the library's
2761 messages according the type. The affected file is the
2762 lib/silcclient/silcapi.h.
2764 * Added two new functions to lib/silcclient/silcapi.h:
2765 silc_client_del_client and silc_client_del_client_by_id.
2766 Affected file lib/silcclient/idlist.c.
2768 * Moved the clientincludes.h from includes/ to silc/ and
2769 serverincludes.h from includes/ to silcd/.
2771 * The modes for the CMODE and CUMODE are now passed as
2772 uint32 for application with COMMAND_REPLY. The affected
2773 file is lib/silcclient/command_reply.c.
2775 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * /WHOIS without arguments shows client's own information.
2778 Affected file lib/silcclient/command.c.
2780 * Changed PING to not accept any arguments. The specs
2781 says that client can ping only the connected server so
2782 requiring an argument is not needed. Affected file is
2783 lib/silcclient/command.c.
2785 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Fixed a fatal bug in private message sending and reception
2788 encryption and decryption when using private message keys.
2789 The implementation was incorrect and did not follow the
2790 specification. It causd that some of the message were
2791 lost since it did not use the sending and receiving keys
2792 as the protocol suggests. This has been fixed and will cause
2793 incompatibilities with older clients when sending private
2794 message encrypted with private message keys. Affected files
2795 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2796 and various other in Irssi SILC Client.
2798 Added `responder' boolean argument to the functions
2799 silc_client_add_private_message_key[_ske] to indicate when
2800 the key is added as responder or initiator of the key
2803 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Removed the silc_ske_check_version function and created
2806 a SilcSKECheckVersion callback. Added also a function
2807 silc_ske_set_callbacks that is now used to set all SKE
2808 callbacks. The callback functions are not given to
2809 the SKE functions anymore, but this function is used to
2812 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2814 * Added `silc_version' argument to the silc_client_alloc
2815 to define the version of the application for the library.
2816 The library will use the version string to compare it
2817 against the remote host's (usually a server) version
2818 string. Affected file lib/silcclient/silcapi.h
2820 * Added the KE protocol context to Key Agreement context
2821 in client library so that we can abort the SKE if it
2822 is in process when we get timeout. Affected file is
2823 lib/silcclient/client_keyagr.c.
2825 * Do not resolve the client ID forever if it returns in the
2826 first time that such client does not exist. This was done
2827 for example with private message. Affected file is
2828 lib/silcclient/client_prvmsg.c.
2830 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Do not add regex.h for WIN32. The affected file
2833 includes/silcincludes.h.
2835 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2836 not work yet 100%. It generates the DLL's automatically
2837 when compiling with --with-win32 under cygwin.
2839 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * lib/contrib/regex.c is not compiled on WIN32.
2843 * Added silc_net_get_socket_opt function to the
2844 lib/silcutil/silcnet.h.
2846 * Added includes/silcwin32.h for WIN32 specific includes
2849 * Do not use ptime structure or any of the posix process
2850 functions on WIN32 in lib/silccrypt/silrng.c.
2852 * Added silc_gettimeofday to provide generic function
2853 for struct timeval on all platforms. Added the function
2854 to lib/silcutil/silcutil.h.
2856 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2859 library as they clearly belong there. As a plus side we
2860 can make the actual socket connection routines platform
2863 Added also new generic function silc_socket_read and
2864 silc_socket_write (that used to be silc_packet_[read/write].
2865 The implementation of these are platform specific.
2867 * Added WIN32 specific routines of silc_socket_[read/write]
2868 to lib/silcutil/win32/silcwin32sockconn.c.
2870 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Added preliminary support for native WIN32 compilation under
2873 cygwin (using the -mno-cygwin option for GCC) to the
2874 ./configure.in.pre. The --with-win32 now prepares the
2875 compilation for native WIN32.
2877 * Rewrote the SILC Scheduler interface in the file
2878 lib/silcutil/silcschedule.h. The scheduler is now context
2879 based and does not have anymore any global static scheduler.
2880 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2881 and created lib/silcutil/win32 directory for WIN32 based
2884 * Added Unix specific network routines to the
2885 lib/silcutil/unix/silcunixnet.c and the old
2886 lib/silcutil/silcnet.c includes now only generic routines.
2888 Added WIN32 specific network routines to the
2889 lib/silcutil/win32/silcwin32net.c.
2891 * Added Unix specific utility functions from the
2892 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2894 * Added WIN32 SILC Scheduler to the file
2895 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2898 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Do not handle JOIN notify in the server if the target client
2901 is not registered (idata->registered == FALSE). The affected
2902 file is silcd/packet_receive.c.
2904 * Update the nickrec->founder in event_cumode in the Irssi SILC
2905 client. Affected file irssi/src/silc/core/silc-channels.c.
2907 * Fixed the CUMODE_CHANGE notify handling in the server when
2908 server and router are announcing their clients on channels.
2909 Now the mode changes are saved and notified correctly. The
2910 affected file is /silcd/packet_receive.c.
2912 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2913 They really did not replace the cache entry in the ID Cache.
2914 Now they do that. Affected file silcd/idlist.c.
2916 * Fixed the KICK notify handling in the Irssi SILC client to
2917 update the channel records so that the kicked client does not
2918 appear to be on the channel. The affected file is
2919 irssi/src/silc/core/silc-channels.c.
2921 * Always update the conn->current_channel when executing command
2922 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2924 * Fixed the KILL notify handling in Irssi SILC client to remove
2925 the killed client on all channels.
2927 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Fixed the silc_parse_command_line to remove extra spaces
2930 from the start and end of the arguments. Affected file is
2931 lib/silcutil/silcutil.c.
2933 * Cancel and free any active protocol in the function
2934 silc_server_close_connection. Affected file silcd/server.c.
2936 * Cancel and free any active protocol in the function
2937 silc_client_close_connction. Affected file is
2938 lib/silcclient/client.c.
2940 * Do not execute the KILL command for clients that are in
2941 history (ie. they are not in the network). Affected file is
2944 * Fixed KILL notify handling, client does not crash anymore.
2945 Affected file irssi/src/silc/core/silc-channels.c.
2947 * Reduced the default packet buffer size from 2048 to 1024 in
2948 lib/silccore/silcpacket.c.
2950 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2951 counter to the SKE context that is incresed when the SKE library
2952 performs async operation outside the library. If the outside
2953 process frees the SKE context and FREED status will be set
2954 and the library will detect after the sync operation that the
2955 libary is freed. The affected files are
2956 lib/silcske/silcske[_status].[ch].
2958 * Resolve the client entry information in the function
2959 silc_client_channel_message to assure that NULL pointer is not
2960 passed as client entry to the application. */
2962 * Fixed the task timeout calculation to assure that there is
2963 never negative timeouts. The affected file is
2964 lib/silcutil/silcschedule.c.
2966 * Fixed the channel user mode notification sending in server.
2967 It was sent point-to-point to the router (or to server by router)
2968 but it needs to be destined to a channel. The routines now
2969 supports sending the channel user mode notifys to the channels
2970 when announcing clients and channels. Affected files are
2971 silcd/server.c and silcd/packet_receive.c.
2973 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2974 It did not actually replace the old channel entry in the cache.
2975 Affected file lib/silcclient/client_notify.c.
2977 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Fixed a possible crash in silc_packet_send_prepare. It now
2980 assures always that there is enough space in the buffer and
2981 at the tail area of the buffer (for MAC).
2983 Fixed the inbound buffer reallocation in silc_packet_read.
2984 It was old code and did not handle the reallocation correctly.
2987 The affected file is lib/silccore/silcpacket.c.
2989 * Fixed buffer overflow in silc_parse_nickname in the file
2990 lib/silcutil/silcutil.c.
2992 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * make install generates new server keys only if there is not
2997 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3000 Added check that if the NOREPLY is set then we will not send
3001 the away message. This avoids infinite loop of away messages
3002 if both clients are away. The affected file is
3003 lib/silcclient/client_prvmsg.c.
3005 * Fixed client crash if /NICK was given without arguments.
3006 Affected file lib/silcclient/command.c.
3008 * Server does not send the invite list in INVITE command back
3009 to the client if the list was not altered. Added this notion
3010 to the protocol spec as well. Affected file silcd/command.c.
3012 Fixed possible crash in INVITE command by checking the
3013 value of silc_server_get_client_route command.
3015 * Fixed the INVITE notify type handling. The arguments are now
3016 taken in correct order and client does not crash. The affected
3017 file is irssi/src/silc/core/silc-channels.c.
3019 Removed the "Inviting xxx to channel" message from the
3020 client library away and let the application handle it.
3021 Affected file lib/silcclient/command.c. Added that message
3022 to Irssi SILC client's message formats.
3024 * Fixed CMODE command crash in client. It now checks the
3025 amount of arguments correctly and does not crash. The affected
3026 file is lib/silcclient/command.c.
3028 * Do not create new channel automatically in silc_channels_join
3029 but check whether the channel by that name already exists.
3030 Affected file irssi/silc/core/silc-channels.c.
3032 * Do not send the SERVER_SIGNOFF to router if the disconnected
3033 entity was the router. Affected file silcd/server.c.
3035 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3036 SILC client as it was missing from there.
3038 Added the handling of the KICK notify to the Irssi SILC client
3039 as it was missing. Added "you have been kicked" message to
3040 Irssi SILC client's message modules formats.
3042 Added the handing of the KILL notify to the Irssi SILC client
3043 as it was missing. Added the kill message module formats
3046 The affected file is irssi/src/silc/core/silc-channels.c.
3048 * The router did not save the channel mode the server announced.
3049 Affected file silcd/packet_receive.c.
3051 * Fixed a possible crash in INFO command in server. If the
3052 server did not provide the server info it crashed. Affected
3053 file silcd/command.c.
3055 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Fixed the GETKEY command in the server to check also the
3058 global list. Otherwise the GETKEY would not work correctly
3059 in normal SILC server. Affected file silcd/command.c.
3061 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Fixed GETKEY crash, it crashed if the command did not succseed.
3065 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3068 is now real and not just an macro interface to GMP.
3070 Removed the entire GMP from the source tree and imported new
3071 NSS MPI library instead. Reason for removing GMP is that it is
3072 extremely large and compiles extremely slow. The NSS MPI
3073 is only a few files and compiles in less than 10 seconds.
3074 The speed is also about the same as GMP. The MPI is imported
3075 to lib/silcmath/mpi.
3077 If the system has GMP installed we will still use the GMP.
3078 If it is not then the NSS MPI will be compiled.
3080 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Merged a long nickname (127 characters long) crash bugfix from
3083 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3085 * Merged a freed memory reference bugfix from Irssi CVS tree.
3086 Affected file irssi/src/core/commands.c.
3088 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Added the server's public key sving and verification to the
3091 server when performing the SKE. This was missing and the
3092 remote server's (or router's) public key was accepted without
3093 checking whether we have it previously or trust it at all.
3094 Affected file silcd/protocol.c.
3096 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Check in the silc_server_timeout_remote if protocol is active
3099 and make sure that the protocol's final callback is called so
3100 that all memory if freed. Affected file silcd/server.c.
3102 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * silc_server_whois_send_reply crashed the server if the nickname
3105 was 127 characters long. Affected file silcd/command.c.
3107 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Added sanity check to the silc_server_new_client. If the hostname
3110 is provided inside username then check that the provided hostname
3111 really is the same as the resolved one. If the hostname was not
3112 resolved then check it from the public key. Affected file is
3113 silcd/packet_receive.c.
3115 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3116 if the server disconnected us and the connection is not valid
3117 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3119 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3120 the library to the lib/silcutil/silcutil.[ch].
3122 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Close log file after open. Affected file
3125 lib/silcutil/silclog.c.
3127 * Check whether sock == NULL in silc_client_send_packet and return
3128 if it is. Affected file lib/silcclient/silcclient.c.
3130 * Check rec->entry == NULL in the Irssi SILC Client before
3131 sending the channel message. Affecte file is
3132 irssi/src/silc/core/silc-servers.c.
3134 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Merged a splitted window bugfix from Irssi CVS tree. The
3137 affected file is irssi/src/fe-text/textbuffer-view.c.
3139 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3140 It did not print nickname.
3142 * Improved the distributions system a bit.
3144 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3147 irssi/src/fe-text/gui-window.c.
3149 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3150 to in-active server. The affected file is
3151 irssi/src/silc/core/client_ops.c.
3153 * Resolve the client in USERS command reply if the entry does
3154 not have username resolved. The affected file is
3155 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3156 command to WHOIS command to really resolve stuff. The USERS
3157 is not used any more in any critical section so WHOIS can
3158 be used even though it might be slower than IDENTIFY.
3160 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3163 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Changed the protocol API a bit more consistent in the
3166 lib/silccore/silcprotocol.[ch].
3168 * Changed the following headers to ROBODoc format:
3170 lib/silccore/silcpayload.h
3171 lib/silccore/silcprotocol.h
3172 lib/silccore/silcsockconn.h
3174 All core library headers are now formatted.
3176 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Fixed a bug in Irssi SILC client; do not show that you are
3179 server/router operator if you really are not. Affected file is
3180 irssi/src/silc/core/client_ops.c.
3182 * Renamed silc_command_free_payload to silc_command_payload_free.
3183 Affected file lib/silccore/silccommand.h
3185 * Added silcmath.h to include the prototoypes of various routines
3186 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3189 * Changed the following headers to ROBODoc format:
3191 lib/silccore/silcchannel.h
3192 lib/silccore/silccommand.h
3193 lib/silccore/silcid.h
3194 lib/silccore/silcidcache.h
3195 lib/silccore/silcmode.h
3196 lib/silccore/silcnotify.h
3197 lib/silccore/silcpacket.h
3198 lib/silcmath/silcmath.h
3200 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Added checking to the server code not to start the server if
3203 ciphers and stuff are not configured properly. Affected files
3204 silcd/serverconfig.[h] and silcd/server.c.
3206 * Changed the layout of the header files of the public interfaces
3207 in the SILC libraries. The new layout supports ROBODoc
3208 documentation tool (and some others) so that it is easy to create
3209 a library reference manual. All the other headers and source
3210 code must still follow the CodingStyle document. Also source
3211 code must not include these ROBODoc stuffs, only the headers.
3212 Furthermore, all public interface headers must now be named
3213 by using `silc' prefix, example: silcapi.h, silccipher.h.
3214 Some files were renamed due to this. All the other headers
3215 must not be used as public interfaces. I will update the
3216 CodingStyle document later. Changed following headers, so far:
3218 lib/silcclient/silcapi.h
3219 lib/silccore/silcauth.h
3220 lib/silccore/silcprivate.h
3221 lib/silccrypt/silcdh.h
3223 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Removed silc_client_packet_send_flush from the client library
3228 as it is not needed. Affected file lib/silcclient/client.[ch].
3230 * Added printing of message of unresolved authentication method
3231 to the Irssi SILC client. Added it to the module formats.
3232 Removed the same message from the client library.
3234 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Added new distribution feature, DISTLABEL. Every distribution
3237 can define own preprocessor label that can be used in the
3238 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3239 file distributions, acconfig.h.pre and prepare.
3241 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Added Makefile.defines_int to include the actual definitions
3244 for Makefile.defines.in. Tested the new distribution system,
3245 created distributions and tested installation.
3247 * Added AWAY message printing to the Irssi SILC client. Added
3248 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3250 * Added SCONNECT command to call the SILC's CONNECT command.
3251 Cannot use CONNECT directly since Irssi uses that internally.
3252 Affected file irssi/src/silc/core/silc-servers.c.
3254 Added ACTION local command. It is same as ME command but takes
3255 the channel as mandatory argument.
3257 Rewrote some of the Irssi's help files to suite for SILC
3260 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added Makefile.defines[.in] that should for now on be included
3263 in all Makefile.am file in the source tree. That file includes
3264 all common compilation definitions for SILC source tree.
3266 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Minor changes to the ./prepare script to change the package
3269 name according the distribution name to the configure.in.
3271 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Created new distribution system. Added file `distributions'
3274 that defines all the distributions that can be created out of
3275 the SILC source tree. The ./prepare script now reads that
3276 file to determine how to prepare the distributions. The
3277 first argument to the ./prepare is the name of the distribution
3278 and second is the version of the distribution. If given
3279 without arguments it creates the default (toolkit) distribution
3280 with the default version (defined in ./prepare).
3282 All Makefile.am files that are subject to the distributions
3283 are now named as Makefile.am.pre. These are ./Makefile.am
3284 and lib/Makefile.am. Others may be changed later.
3286 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added invite list, ban list, some key management and connection
3289 error message printing to module formats in the Irssi SILC client.
3291 * Added new silc_client_set_away_message to set the away message
3292 that is back to the person who sent private message. The
3293 affected file lib/silcclient/silcapi.h and the
3294 lib/silcclient/client_prvmsg.c.
3296 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Fixed the private message sending in the Irssi SILC client,
3299 added local command KEY to the Irssi SILC client.
3301 Added key management and key agreement message formats to the
3302 irssi/src/fe-common/silc/module-formats.[ch].
3304 Added USERS (alias WHO) printing, server/router operator
3305 indication and LIST command printing to the module formats.
3307 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Fixed channel joining notify handling, cumode notify handling
3310 from Irssi SILC client.
3312 * Added SILC specific module-formats to the Irssi SILC client so
3313 that SILC specific message hilighting, colors etc is possible.
3314 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3316 Added channel mode, channel user mode, actions, notices,
3317 whois and whowas printing to the the module-formats.c.
3319 * Fixed a bug in channel deletion in the server. The channel
3320 is not left to the cache even if the channel founder auth mode
3321 is set when there are no users anymore on the channel. Affected
3322 file silcd/server.c.
3324 * The silc_net_localhost now resolves the entire hostname including
3325 the domain name. Affected file lib/silcutil/silcnet.c.
3327 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Changed the ask_passphrase client operation to be ascynchronous.
3330 It has now a completion callback and a context that the
3331 application must call after it has got the passphrase from
3332 the user. Affected files lib/silcclient/silcapi.h,
3333 lib/silcclient/protocol.c, lib/silcclient/command.c and
3336 Added SilcAskPassphrase callback that the application calls
3337 to deliver the passphrase to the library.
3339 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3340 The public key verification and especially a certificate
3341 verification is asynchronous procedure.
3343 Added new SILC_SKE_STATUS_PENDING status to indicate the
3344 request is pending and a callback will be called to finalize
3347 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3348 indicate that remote end did not send its public key (or
3349 certificate), even though we require it. Added check for this
3350 condition in the SKE. This was a security bug, now fixed.
3352 Defined new SilcSKEVerifyCbCompletion callback that is called
3353 when the verification process is completed.
3355 The affected files lib/silcske/silcske_status.h and
3356 lib/silcske/silcske.[ch].
3358 * Changed the verify_public_key client operation to be async
3359 as well. Defined SilcVerifyPublicKey callback that is used to
3360 indicate the success of the public key verification process.
3362 Changed the server and client to use the new async client
3365 * Changed the Irssi SILC client's internal scheduler to be called
3366 twice as many times as it used to be. As a result the client
3367 should be a bit faster now. Affected file is
3368 irssi/src/silc/core/silc-core.c.
3370 * Added support to Irssi SILC client of asynchronous public key
3371 verification and passphrase inquiry. Affected file is
3372 irssi/src/silc/core/silc-core.c.
3374 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Do not say "You have left channel %s" in client library.
3377 Moved it to the application. Affected files are
3378 lib/silcclient/command.c and silc/client_ops.c.
3380 * Fixed silc_client_get_clients. Command context was not
3381 duplicated and was freed memory in the callback. Affected
3382 file lib/silcclient/idlist.c.
3384 * Do not say "you are now talking..." on JOIN command in the
3385 client library. The appliation must handle it.
3387 * Do not say ".. changed topic to" in command reply in the
3388 client libary. The application must handle it.
3390 * Fixed TOPIC command sending in the client library.
3392 * Fixed a memory leak in silc_client_command_free in the file
3393 lib/silcclient/command.c.
3395 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Imported a modified version of Irssi client to the source tree.
3398 The Irssi will be used to create a new client called
3399 Irssi SILC. Imported to irssi/.
3401 Added silc_core_init_finish function to the Irssi. Affected
3402 file irssi/configure.in.
3404 A lot changes in the Makefile.ams around the irssi tree.
3406 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Do not rehash if the new size is same as the old size of the
3409 hash table, in the silc_hash_table_rehash*. The affected file
3410 lib/silcutil/silchashtable.c.
3412 * Replaced hash_table_del_by_context calls from the server
3413 (when channel->user_list and client->channels) to the
3414 hash_table_del as it is sufficient and faster.
3416 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Added silc_hash_table_list, silc_hash_table_get and the
3419 SilcHashTableList structure to provide an alternative way to
3420 traverse the hash table. The affected files are
3421 lib/silcutil/silchashtable.[ch].
3423 * Changed the server's idlist routines to use the hash table
3424 routines to optimize the code.
3426 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Replaced the client entry's `channel' list and channel entry's
3429 `user_list' list to hash tables for optimized lookup. Changed
3430 the code to use the hash table interface around the code.
3431 Affected file lib/silcd/idlist.[ch].
3433 * Added `auto_rehash' boolean argument to the function
3434 silc_hash_table_alloc to indicate whether the hash table should
3435 auto-rehash when it thinks is appropriate time. It will
3436 increase the hash table size if the there is twice as much
3437 entries in the table than the size of the table, and will
3438 decrease the size if there are twice as less entries than
3439 the size of the table.
3441 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3445 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * silc_idcache_purge_by_context deletes the entry now by context
3448 as it is supposed to do. Affected file lib/silccore/idcache.c.
3450 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3451 client is not anymore valid (WHOWAS givens the info) and not
3452 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3454 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Removed the `data' and `data_len' arguments from the ID Cache
3457 interfaces and added `name' argument. ID Cache does not handle
3458 anymore the binary data only a names associated with given ID.
3460 * When hashing a Client ID with silc_hash_id the entire ID is
3461 not hashed anymore, instead only the hash of the Client ID is
3462 hashed. This way we can access the Client ID from the cache
3463 with Client ID but with the hash of the ID (which is a hash of
3464 the nickname) as well without any difference in performance.
3466 Added also silc_idcache_find_by_id_one_ext to do one on one
3467 searching when we have the actual ID. Added also function
3468 silc_hash_client_id_compare. The affected files are
3469 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3471 * When hashing the name associated with a ID it is always done
3472 in lowercase. This way we can access the cache without worrying
3473 about case-sensitivity, even though, for example nicknames are
3476 * Fixed a bug in server with channel message sending. It put
3477 wrong ID type as destination ID. The affected file
3478 silcd/packet_send.c.
3480 * silc_idcache_del_by_context now deletes from all hash tables
3481 by context. Affected file lib/silccore/idcache.c.
3483 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Changed the client library to use the new ID Cache interface.
3486 Changes around the source tree.
3488 * Added silc_hash_table_rehash_ext to rehash with specific
3489 hash function. Affected file lib/silcutil/silchashtable.[ch].
3491 * Added silc_hash_string_compare to compare two strings in the
3492 hash table. Affected file lib/silcutil/silcutil.[ch].
3494 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added new function silc_idcache_del_by_context into the
3497 lib/silccore/idcache.[ch].
3499 * Changed the server's ID list routines to use the new ID Cache
3500 interface. Changes around the source tree.
3502 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added silc_hash_table_del[_by_context]_ext functions in to the
3505 lib/silcutil/silchashtable.[ch].
3507 Removed silc_hash_table_find_all* routines and added new
3508 silc_hash_table_find_foreach to replace them.
3510 Added silc_hash_table_replace_ext function as extended
3511 replacing function. Separated the simple hash table interface
3512 from the extended hash table interface in the file
3513 lib/silcutil/silchashtable.h.
3515 * Fixed minor bugs and changed it to use some of the new
3516 hash table functions in lib/silccore/idcache.c
3518 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Added new function silc_hash_table_find_all to return all keys
3521 in the hash table by the specified key. As the hash table is
3522 collision resistant it also makes it possible to have several
3523 duplicate keys in the hash table. This function may be used to
3524 find all of the keys from the hash.
3526 Added user_context arguments to the SilcHashFunction,
3527 SilcHashCompare and SilcHashDestructor to deliver user specified
3530 Added new fuctions silc_hash_table_find[_all]_ext to do
3531 extended lookup with specified hash and compare functions and
3532 specified user contexts.
3534 Added new function silc_hash_table_add_ext to add the key
3535 with specified hash function and user context.
3537 Added new function silc_hash_table_foreach to traverse all
3538 entrys in the hash table. Added SilcHashForeach callback
3541 Added new function silc_hash_table_del_by_context to delete
3542 the entry only if the context associated with the key matches.
3544 Affected files are lib/silcutil/silchashtable.[ch].
3546 * Removed silc_hash_[server/client/channel]_id and added just
3547 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3548 silc_hash_id_compare to compare two ID's using as the hash table
3549 comparison function. Added also silc_hash_data to hash
3550 binary data and silc_hash_data_compare to compare it.
3552 * Removed silc_idlist_find_client_by_hash as it is not needed
3553 anymore. Affected file silcd/idlist.[ch].
3555 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3556 to use internally the SilcHashTable. The new ID Cache is a lot
3557 faster than the old one. Some of the ID Cache interface was also
3558 rewritten and obsolete and stupid functions were removed.
3560 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added entry_count field to the SilcHashTable to keep the number
3563 of the entries in the table. Implemented the function
3564 silc_hash_table_rehash. Added new function
3565 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3567 Fixed a minor bug in silc_hash_table_free.
3569 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3570 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3571 into the lib/silcutil/silcutil.[ch].
3573 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Implemented a collision resistant hash table into the
3576 lib/silcutil/silchashtable[ch]. See the header and the source
3577 for the SilcHashTable API.
3579 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Merged dotconf version 1.0.2 into lib/dotconf.
3583 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Do not compile anything in lib/silcsim/* if the SIM support
3586 is not enabled. The tree should now compile without problems
3589 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Compiled the SILC under cygwin. Compiled and tested briefly
3592 without problems. More tests needed. The SIMs didn't compile
3595 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3597 * Fixed possible crash in silc_get_username in the
3598 lib/silcutil/silcutil.c.
3600 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Fixed a va_arg in silc/client_ops.c.
3604 * Oops, RC5 routines were named AES and caused some problems
3605 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3607 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Added new SilcIDIP structure into the lib/silccore/id.h and
3610 replaced the old `ip' fields from all SILC ID's to that type.
3611 This is a step towards IPv6 support.
3613 The silc_id_get_len takes now the ID as an extra argument.
3614 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3615 both IPv4 and IPv6 based ID's.
3617 The affected files are lib/silccore/id.[ch] and other files
3618 around the tree using these routines.
3620 * Removed the ID length arguments in server from various
3621 silc_server_send_notify_* routines -> they are not needed
3624 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Fixed memory leak in silc_encode_pem_file in the file
3627 lib/silcutil/silcutil.c.
3629 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Check minor version as well in the SKE. Affected files are
3632 silcd/protocol.c and lib/silcclient/protocol.c.
3634 * Added --identifier option to the server so that an identifier
3635 can be when creating the public key for the server. Affected
3636 file is silcd/silcd.c.
3638 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3639 lib/silccrypt/silcpkcs.c.
3641 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Register default ciphers and stuff when using -C option with
3644 the server. Affected file sildc/silcd.c.
3646 * Put back the servers public key filename format, it is better
3647 than the new one. For now, the client keys are saved with the
3648 new filename format. The affected file silc/client_ops.c.
3650 * Implemented the Cipher API for the rest of the ciphers that
3651 did not implement it or implemented it the wrong way.
3653 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Register default ciphers and stuff when using the -S option
3656 in the client. Affected file silc/silc.c. Same also when
3657 creating new key pair with -C option.
3659 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Fixed the silc_verify_public_key client operation function to
3662 save the public keys differently. The fingerprint is now
3663 used as filename and not the hostname. This way also the
3664 client keys are saved uniquely and not with hostnames. The
3665 affected file is silc/client_ops.c.
3667 * Trimmed the silc_hash_fingerprint function to remove extra
3668 whitespaces from the end of the fingerprint. The affected
3669 file is lib/silccrypt/silchash.c.
3673 * Added silc_cipher_register_default function to register all
3674 default ciphers. It can be used when configuration files
3675 does not exist and the application does not want any specific
3676 ciphers in any specific order.
3678 The SilcDList is now used as silc_cipher_list dynamically
3679 allocated cipher list. Removed the static list all together
3680 and now all ciphers must be allocated to the dynamic list.
3681 The silc_cipher_alloc routine was changed to check only the
3684 All silc_cipher_* routines that used to return int returns
3687 The affected files lib/silccrypt/silccrypt.[ch].
3689 * The same thing was done to silc_hash_* as for silc_cipher_*
3690 routines. Affected files lib/silccrypt/silchash.[ch].
3692 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3693 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3694 Added also silc_pkcs_[un]register[_default] functions.
3695 Removed the data_context from the PKCS API.
3697 * Added silc_hmac_register_default function to register default
3698 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3699 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3700 to unregister all hmacs at once.
3702 * Register the default ciphers, hash functions, PKCSs and HMACs
3703 if client's configuration file does not exist. The affected
3706 * The client did not load the hash functions from the SIM
3707 modules at all. Added support for this. Affected file is
3708 silc/clientconfig.c.
3710 * When decoding public key with silc_pkcs_public_key_decode, check
3711 the supported algorithm only if PKCS are registered. Affected
3712 file lib/silccrypt/silcpkcs.c. The same was done with the
3713 silc_pkcs_private_key_decode.
3715 * Fixed the SILC List routines to keep the list always in order.
3716 It used to change the list's order when traversing the list but
3717 not it preserves the order. Affected file lib/trq/silclist.h.
3719 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Added the client library to use the SilcSocketConnection's
3722 reference counter (by silc_socket_dup) to prevent the bug that
3723 the socket object may be freed underneath async operation.
3725 * The name resolv library checking fixes in the configure.in.pre.
3728 * Created new version of the protocol drafts for future
3729 development. The -03 drafts are the ones that will be changed
3730 in the trunk now and the -02 will remain as they are.
3732 * Send list of CUMODE notifys to the router when announcing
3733 the channel users to the router. Affected file silcd/server.c.
3734 If the router receiving channel founder CUMODE for a channel
3735 that already has channel founder it will send CUMODE notify
3736 to the sender to remove the channel founder rights from the
3737 announced client. Affected file silcd/packet_receive.c.
3739 * The CUMODE notify may now use Server ID as well as the entity
3740 who changes the mode. Updated protocool specs.
3742 * Updated INSTALL and README files.
3744 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * New web pages in the http://silc.pspt.fi. The pages was
3751 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Implemented the [DenyConnectin] config section in the server.
3754 Added silc_server_config_denied_conn to check whether incoming
3755 connection is denied. Affected file silcd/serverconfig.[ch].
3757 * Do not check the ports when checking the incoming configuration
3758 data if the port is 0, meaning any. Affected file is
3759 silcd/serverconfig.c.
3761 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed buffer overflow in silc_string_compare in the file
3764 lib/silcutil/silcutil.c.
3766 * Fixed double free in silc_server_command_leave in the file
3769 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Fixed the version checking in the server. Affected file is
3774 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Fixed the configuration data fetching when accepting new
3777 connections in the server. Affected file silcd/server.c.
3779 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Added `sender_entry' argument to the function
3782 silc_server_packet_relay_to_channel so that we can check
3783 whether some destination actually belongs to the same route
3784 the sender belongs (ie, we must not resend the packet to the
3785 sender). Affected file silcd/packet_send.[ch].
3787 * Added `servername' field to the SilcClientEntry in the server
3788 to hold the name of the server where client is from. Affected
3789 file is silcd/idlist.h.
3791 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Moved the channel message encrypting in the router betwen
3794 router connections from silc_server_channel_message to the
3795 silc_server_packet_relay_to_channel since we want to check
3796 whether we have anybody channel before encrypting anything.
3797 Affected files silcd/packet_[receive/send].c.
3799 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Fixed the [AdminConnection] server config section to support
3802 multiple entries. Affected file silcd/serverconfig.c.
3804 * Added support into the server to check the validity of the
3805 incoming connection before executing any KE or authentication
3808 * The connection configuration is now saved to the KE and
3809 connection auth protocol contexts and not fetched anymore in
3810 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3812 * The local hosts listenning address and port is also resolved
3813 now when starting the server. We want to have the socket object
3814 to include the real address and port for the listener. Added
3815 new function silc_net_check_local_by_sock into the files
3816 lib/silcutil/silcnet.[ch].
3818 * Fixed a broadcast bug in server -> do not broadcast if we
3821 * Fixed a routing bug. Do not route broadcast packets ever.
3822 Broadcast packets must be processed always and not routed since
3823 they may be destined to some other host than yourself and thus
3824 would get routed without no good reason. Affected file is
3827 * Added function silc_server_config_is_primary_route to check
3828 whether primary router connection has been configured (a router
3829 configuration that we are initiating). If there is not, we
3830 will assume that there is only two routers in the SILC network
3831 and we will use the incoming router connection as our primary
3832 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3834 * Changed the order of the broadcasting. Broadcast _after_ the
3835 packet has been processed not before. Affected file is
3838 * Fixed a [ClientConnection] parsing bug. The port was never
3839 parsed correctly thus resulting to port 0. Affected file
3840 silcd/serverconfig.c.
3842 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3843 argument and did not set the broadcast packet flag. Affected
3844 file silcd/packet_send.c. Fixed same bug in the function
3845 silc_server_send_notify as well.
3847 * If we receive NEW_ID packet for our own ID in the server, ignore
3850 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Removed the nickname from the Private Message Payload.
3855 Updated the code and the protocol specs.
3857 * Updated protocol specs for submitting to the IETF.
3859 * Tweaked the Random Number Generator a bit. Affected file
3860 lib/silccrypt/silcrng.c. Exported a new function
3861 silc_rng_[global]_add_noise which can be used to add more
3864 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Do not parse packets with different timeout when protocol
3867 is active -> may cause problem with rekey. Affected file
3870 * When server receives signoff notify it must not create
3871 new channel key if the client is on any channels since the
3872 sender of the signoff notify will create it.
3874 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added printing of error messages during SKE protocol from the
3877 failure packet sent by server during SKE. Affected file
3880 * Removed the client's failure_callback handling with timeout
3881 and handle it immediately when received.
3883 * The SKE library returned wrong type in SUCCESS and FAILURE
3884 packets. They must be 32 bit MSB not 16 bit MSB.
3886 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Ok, rewrote the logic of the re-key and now it seems to work.
3889 I tested it on high traffic with frequent re-keys without
3890 problems. Added hmac_receive (and renamed hmac to hmac_send)
3891 in SilcClientConnection in lib/silcclient/client.h and
3892 in SilcIDListData in silcd/idlist.h. Also, removed the
3893 SilcPacketParserContext's cipher and hmac fields as they are
3894 not needed anymore and actually caused some problems when
3895 the ciphers and hmac's changed underneath the packet parser.
3897 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * If re-key protocol is active then process the incoming packets
3900 synchronously since we must assure that icoming packets encrypted
3901 with the old key is processed before the new keys is set to
3902 use. This is true other packets than for REKEY packets.
3903 Affected file silcd/server.c. The same was done to client library
3904 as well, affected file lib/silcclient/client.c.
3906 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Fixed bug in client and server to accept the force send if
3909 the packet is send from silc_[server/client]_packet_process
3910 function. Otherwise the packets are never delivered, oops.
3912 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Disable force sending of packets when REKEY protocol is active.
3915 We must assure that no packet is sent directly when rekey is
3916 performed. All packets must be sent through packet queue.
3917 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3918 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3919 function is silc_[server/client]_packet_send_real to check
3922 * Replaced the SIM paths from example config files to
3923 /usr/local/modules. Also, make install creates now
3924 /usr/local/silc/logs directory to hold all the SILC server
3927 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Made the configure.in.pre work on Solaris. Patch by salo.
3931 * Made all ciphers compatible with non-x86 machines. Defined
3932 CBC mode macros into lib/silccrypt/ciphers_def.h.
3934 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Fixed the make install.
3938 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * When MAC computation fails the silc_packet_decrypt returned 0
3941 even though it was supposed to return -1. Fixed this. The
3942 affected file is lib/silccore/silcpacket.c.
3944 * Do not replace the config files in /etc/silc (in make install)
3945 if they already exist. Affected file ./Makefile.am.
3947 * Do not send re-key packets immediately but through packet queue.
3948 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3950 * Changed silc_net_check_host_by_sock to return FALSE if the
3951 IP/DNS could not be resolved. Though, it returns the IP address
3952 now even if it could not resolve it (but returns also FALSE).
3953 Affected file lib/silcutil/silcnet.[ch].
3955 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added silc_pkcs_decode_identifier to decode the public key's
3958 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3959 Added also silc_pkcs_free_identifier. Added also new context
3960 SilcPublicKeyIdentifier.
3962 * Added -S option to the silc client. It is used to dump the
3963 contents of the specified public key file.
3965 * Changed the PKCS api to return the public key length when
3966 setting the public key.
3968 * Fixed a fatal bug in the public and private key file loading.
3969 Affected file lib/silccrypt/silcpkcs.c.
3971 * Execute the packet parsing for client with zero (0) timeout
3972 if the protocol is active. Affected file silcd/server.c.
3974 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Made the key generation options to the silcd program. Added
3977 -C option, equivalent to client's option.
3979 * Added new [ServerKeys] config section to the server. It
3980 configures the server's public and private key.
3982 * Defined generic Public Key Payload into the protocol
3983 specification to send specific type of public keys and
3986 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3987 public key or certificate.
3989 * Implemented the GETKEY command to the server and to the
3990 client library and on user interface.
3992 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Made preliminary `make install' work.
3996 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Added SilcServerRekey context into silcd/idlist.h.
4000 * Added the PFS support as defined in the specification to the
4001 SKE protocol. Affected files lib/silcske/*.c.
4003 * Added `ske_group' field to the SilcServerRekey context to hold
4004 the number of the SKE group that is used with PFS in re-key.
4005 Affected file silcd/idlist.h.
4007 * Added PFS re-key support to the server. Affected file is
4010 * Added silc_protocol_cancel to cancel execution of the next
4011 state of the protocol. Affected file is
4012 lib/silccore/silcprotocol.[ch].
4014 * Added the re-key support with and without PFS to the client
4015 library. Re-key is performed once in an hour, by default.
4017 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4018 Added silc_client_rekey_callback and silc_client_rekey_final.
4019 Affected files are lib/silcclient/protocol.[ch] and
4020 lib/silcclient/client.[ch].
4022 * Removed the `hmac_key' and `hmac_key_len' fields from the
4023 SilcClientConnection structure; not needed. Affected file is
4024 lib/silcclient/client.h.
4028 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Do not ask whether user wants to use the negotiated private key
4031 for private messages, just use it. Affected file is
4032 silc/local_command.c.
4034 * Added `send_enc_key' and `enc_key_len' fields to the
4035 SilcIDListData structure since they are needed in the re-key
4036 phase. Affected file is silcd/idlist.[ch].
4038 * Implemented the simple re-key protocol into the server.
4039 Affected files silcd/server.c and silcd/protocol.[ch]. The
4040 re-key will be performed once in an hour, by default.
4042 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4043 Added silc_server_rekey, silc_server_rekey_callback and
4044 silc_server_rekey_final.
4046 * Removed Tunneled flag from the protocol. Updated the code
4047 and the specifications.
4049 * Adde `pfs' field to the SilcIDListData to indicate whether
4050 the PFS is to be performed in the re-key. Affected file is
4053 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4056 int64 of at least the xintXX size. If void * is less that 4
4057 bytes uint32 * will be used. Defined bool as boolean.
4059 * Changed _ALL_ unsigned long and unsigned int to uint32,
4060 unsgined short to uint16 in the source tree.
4062 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4063 not handle clients that has entry->data.registered == FALSE.
4064 They are not in the network anymore. Affected file is
4067 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Implemented the sending of the SERVER_SIGNOFF notify in the
4070 server. Affected file is silcd/server.c.
4072 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4073 Added also silc_notify_payload_encode_args into the
4074 lib/silccore/silcnotify.[ch].
4076 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4077 Affected file silcd/packet_receive.c.
4079 * Implemented the SERVER_SIGNOFF notify handling in the client
4080 library. Affected file lib/silcclient/client_notify.c. Also,
4081 implemnted the printing of the SERVER_SIGNOFF info to the
4082 application. Affected file silc/client_ops.c.
4084 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4085 if the deleting was successful. Affected file silcd/idlist.[ch].
4087 * Added support for public key authentication in the connection
4088 authentication protocol in the client library. Affected file
4089 lib/silcclient/protocol.c.
4091 * Changed the server's silc_idlist_get_clients_by_* interface
4092 to support already allocated array so that new entries may be
4093 added to pre-allocated array. Affected file silcd/idlist.[ch].
4094 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4095 and command replies.
4097 * All command reply functions in the server now calls the
4098 pending command callback even if error occured. This way the
4099 error will be delivered to the client as well. Affected files
4100 silcd/command.c and silcd/command_reply.c.
4102 * Fixed INFO command to return local server's info if no server
4103 was provided. Affected file lib/silcclient/command.c.
4105 * Removed RESTART command for good. Updated the code and the
4108 * Rewrote parts of the task system. It is a bit simpler now.
4109 Removed unsued task priorities. The affected files are
4110 lib/silcutil/silctask.[ch].
4112 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Moved the USERS printing from the library to the application.
4115 Affected files lib/silcclient/command.c and silc/client_ops.c.
4117 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added channel key re-key support. The re-key is perfomed
4122 only by the router and is done once in an hour. Added `rekey'
4123 field to the SilcChannelEntry in the server. Affected files
4124 silcd/server.c and silcd/idlist.h.
4126 * Added silc_task_unregister_by_context into the file
4127 lib/silcutil/silctask.[ch].
4129 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Added SILC_UMODE_GONE mode to indicate when the client is not
4132 present in the SILC network. Added also support to the local
4133 command AWAY that will set this mode. Added support of showing
4134 "xxx is gone" in WHOIS command. The USERS command shows the
4135 gone status as well.
4137 * Fixed setting server and router operator privileges in the
4138 server's UMODE command. Affected file silcd/command.c.
4140 * Merged the SKE KE1 and KE2 payloads into one payload. The
4141 new KE payload is equivalent to the old KE2 payload.
4143 Cleaned up the SKE Start Payload parsing. It now uses the
4144 simple buffer unformatting to do the parsing. A lot faster
4147 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4148 to the SKE that is used to indicate whether both of the SKE
4149 parties should perform authentication. By default only the
4150 responder performs authentication. By setting this flag also
4151 the initiator must do authentication. By default it is unset
4152 since in normal SKE case, client to server connection, only
4153 the responder should do authentication. When doing SKE between
4154 two clients both should perform authentication. Updated the
4155 code and the protocol specs.
4157 * A little fix to IDENTIFY command in the server. Search the
4158 client first by hash not nickname. Affected file is
4161 * Fixed the silc_client_close_connection to support closing
4162 the client to client connections wihtout deleting too much
4163 data. Affected file lib/silcclient/client.c.
4165 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4166 are received if protocol used to be active but is not anymore
4167 the application would crash due to NULL pointer dereference.
4168 Affected files silcd/server.c and lib/silcclient/client.c.
4170 * Added `hash' field to the SilcClientConnection to include
4171 the hash function negotiated in the SKE protocol.
4173 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4174 to set the channel founder authentication data. A client can
4175 claim the founder rights later by providing the authentication
4176 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4177 This way the channel founder can regain the channel founder
4178 privileges even it is left the channel. This works only on
4179 local server and the client must be connected to the same
4180 server to be able to regain the founder rights. Updated the
4181 protocol specs accordingly.
4183 Added support to the CMODE command in the client to set the
4184 founder auth data. Read the README to see how to set it.
4186 Added support to the CUMODE command to claim the founder
4187 rights. Read the README to see how to do it.
4189 Added support for the founder authentication to the Channel
4190 Entry in the server. Affected file silcd/idlist.h.
4192 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4193 server's CMODE command. Affected file silcd/command.c.
4195 * Added the following new functions into lib/silccore/silcauth.[ch]:
4196 silc_auth_get_method and silc_auth_get_data.
4198 * The server now saves the remote hosts public key to the
4199 SilcIDListData pointer. Affected file silcd/protocol.c.
4201 * The normal server now does not remove the channel entry from
4202 the cache if the founder authentication data is set. It used
4203 to remove it if the founder was the last one on the channel on
4204 the server and left the channel. The auth data is saved and
4205 if the channel is re-joined later the old entry is used with
4206 the old auth data. Affected files silcd/command_reply.c and
4209 * Removed the `pkcs' field from the SilcIDListData structure
4210 in the server; it is not used. Affected file silcd/idlist.h.
4212 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed packet processing on slow links. Partial packets were
4215 never re-processed because the incoming data buffer was cleared
4216 by the application. Application must not directly clear the
4217 sock->inbuf, the packet processing routines handle it. Fixed
4218 this in client library and in server.
4220 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed the WHOIS and IDENTIFY send reply function to really
4223 check whether to send list or just one entry. Affected file
4226 * Cleaned up the LEAVE command's channel key distribution. The
4227 affected file silcd/command.c.
4229 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4230 can enforce the channel mode as well. In that case the ID
4231 includes the ID of the server. The code now enforces the
4232 mode change if the router have different mode than the server.
4234 * The notify client operation with CMODE_CHANGE notify can now
4235 return NULL client_entry pointer if the CMODE was not changed
4236 by client. Application must check for this.
4238 * Added <Server ID> argument to INFO command to support server
4239 info fetching by Server ID.
4241 * Added silc_server_announce_get_channel_users to get assembled
4242 packets of channel users of the specified channel. Affected
4243 file silcd/server.[ch].
4245 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4246 was freed underneath the ID Cache.
4248 * Re-announce clients when the server received CHANNEL_CHANGE
4249 notify from the router. Affected file silcd/packet_send.c.
4251 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4254 crashed since it did not handle the fact that there is no cipher
4255 called "3" and didn't check the error condition. Now fixed.
4257 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4258 flag. It can be used to send message requests.
4260 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Implemented the RESTART command in the client.
4264 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4265 notice type messages. Added notice printing to the user
4268 * The channel keys are not re-generated if the channel's mode
4269 is PRIVKEY, ie private key on the channel exists. Affected
4270 files silcd/server.c and silcd/command.c.
4272 * Fixed a little bug in channel message delivery when channel
4273 private keys are set in the server. Affected file is
4274 silcd/packet_send.c.
4276 * Changed the setting on channel->on_channel = TRUE from the
4277 silc_client_save_channel_key to the JOIN command reply. The
4278 key payload is not received if the private channel key is set.
4279 Affected file lib/silcclient/command_reply.c and the
4280 lib/silcclient/client_channel.c.
4282 * When the CMODE_CHANGE notify is sent and the channel private
4283 key mode is removed the channel key must be re-generated in
4284 other cells as well. Added this support for the router in the
4285 silcd/packet_receive.c.
4287 * Added new local command NOTICE to send notice message on
4288 channel. Affected file silc/local_command.[ch].
4290 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Added new local command ME to the client. It is used to send
4293 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4294 some action. Affected file silc/local_command.[ch].
4296 * Changed channel_message and private_message client operations
4297 to deliver the message flags to the application. Added also
4298 the `flags' arguments to the silc_client_send_channel_message
4299 and silc_client_send_private_message functions. Affected file
4302 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Redefined the Private Message Payload to support private message
4305 keys and to support the new private message flags. Updated
4306 the protocol specs. Flags makes it possible to have for example
4307 CTCP style messages.
4309 * Added new type SilcPrivateMessagePayload and defined an API
4310 for it in the lib/silcclient/silcprivate.[ch].
4312 * Tested private message private keys successfully. Tested the
4313 private message key set, unset and list commands with the new
4316 * Redefined the Channel Message Payload to include the channel
4317 message flags (equal with private message flags) to support
4318 for example CTCP style messages.
4320 * Defined some of the message (for channel and private message)
4321 flags. Updated the protocol specs and added the flags to the
4322 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4324 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Added SilcKeyAgreementStatus type to the key agreement routines
4327 to indicate the current status and error if one occured.
4328 The status types are defined in the lib/silcclient/silcapi.h.
4330 * Added new local command KEY that is used to set and unset private
4331 keys for channels, set and unset private keys for private messages
4332 with remote clients and to send key agreement requests and
4333 negotiate the key agreement protocol with remote client. The
4334 key agreement is supported only to negotiate private message keys,
4335 it currently cannot be used to negotiate private keys for channels,
4336 as it is not convenient for that purpose.
4338 * Fixed a minor pending callback setting bug in the function
4339 silc_client_get_client_by_id_resolve, now the function works.
4340 Affected file lib/silcclient/idlist.c.
4342 * Added function silc_net_get_local_port to get local bound
4343 port by socket. Added to lib/silcutil/silcnet.[ch].
4345 * Added `sockets' and `sockets_count' fields to the SilcClient
4346 object. They hold the sockets of the listenning sockets in
4347 the client. Listenning sockets may be for example the key
4348 agreement server. Affected file lib/silcclient/client.[ch].
4349 Added functions the silc_client_add_socket and the
4350 silc_client_del_socket. They are exported to the application
4353 * Added ~./silc/clientkeys to support other client's public keys.
4355 * Renamed verify_server_key client operation to verify_public_key
4356 and added one argument to indicate the type of the connection
4357 (server, client etc.).
4359 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added silc_server_connection_auth_request to handle the
4362 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4363 silcd/packet_receive.[ch].
4365 * Added silc_server_send_connection_auth_request into the
4366 silcd/packet_send.c to send the connection auth request packet.
4368 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4371 * Fixed the public key authentication in responder side in the
4372 server. The `auth_data' pointer includes the SilcPublicKey
4373 not the path to the public key. Affected file silcd/protocol.c.
4375 * Implemented the public key authentication in the initiator side
4376 in the server. Affected file silcd/protocol.c.
4378 * Removed the [RedirectClient] config section from the server
4379 configuration. Is not needed and I don't want to implement it.
4381 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Cleaned up the CMODE command in the server. It now works
4384 correctly and supports all the modes defined in the protocol.
4385 Affected file is silcd/command.c.
4387 * Added `hmac_name' field to the SilcChannelEntry in the server
4388 to hold the default HMAC of the channel. It can be set when
4389 creating the channel (with JOIN command). Affected files
4392 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4393 type to indicate the change of the current cipher and hmac
4394 on the channel. Client can safely ignore the <cipher> argument
4395 (if it chooses to do so) since the CHANNEL_KEY packet will
4396 force the channel key change anyway. The <hmac> argument is
4397 important since the client is responsible of setting the new
4398 HMAC and the hmac key into use.
4400 * Fixed the CMODE command in the client library as well.
4402 * Tested CMODE command in router environment successfully.
4404 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Show the version of the remote client (or server) when connecting
4407 to the server. It is logged to the log file. Affected file
4408 is silcd/protocol.c.
4410 * Fixed the KILLED notify handling in the client library. The
4411 client must be removed from all channels when receiving the
4414 Also, do not remove the client entry when giving the KILL
4415 command but when the KILLED notify is received.
4417 * Removed silc_idlist_find_client_by_nickname from the server.
4418 Not needed anymore. Affected files silcd/idlist.[ch].
4420 * Implemented the CHANNEL_CHANGE notify type handling to the
4421 server. Affected file silcd/server.c.
4425 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added silc_server_send_notify_invite to send the INVITE
4428 notify between routers.
4430 * Implemented the INVITE command correctly to the server.
4432 * Implemented the INVITE notify type handling in the server.
4434 * Implemented the INVITE command to the client library and on the
4437 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added function silc_server_get_client_resolve to find the
4440 client entry by ID from all ID lists and then resolve it
4441 (using WHOIS) if it cannot be found. Affected file is
4444 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Implemented the BAN command to the client library.
4448 * The JOIN command in the server now checks the invite list
4451 * Changed the silc_command_reply_payload_encode_va and the
4452 silc_command_payload_encode_va to support that if argument is
4453 NULL it ignores and checks the next argument. Affected file
4454 lib/silccore/silccommand.c.
4456 * Added silc_server_send_notify_ban to send the BAN notify
4457 type between routers.
4459 * Chaned the silc_notify_payload_encode to support that if
4460 argument is NULL it ignores and checks the next argument.
4461 Affected file lib/silccore/silcnotify.c.
4463 * Tested ban lists in router environment successfully.
4465 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Implemented BAN command to the server, in silcd/command.[ch].
4469 * Removed the BAN and INVITE_LIST modes from the CMODE command
4472 * Added function silc_string_match to regex match two strings.
4473 Affected files lib/silcutil/silcutil.[ch].
4475 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Redefined parts of the SilcChannelEntry in the server to support
4478 the new ban and invite lists.
4480 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Redefined the INVITE command. The same command can be used to
4483 invite individuals to the channel but also to manage the invite
4484 list of the channel (to add to and remove from the invite list).
4485 Updated the protocol specs.
4487 * Added new command SILC_COMMAND_BAN that can be used to manage
4488 the ban list of the channel. Updated the protocol specs.
4490 * Removed the channel modes: the SILC_CMODE_BAN and the
4491 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4492 in the CMODE command. The equivalent features are now available
4493 using INVITE and BAN commands. Updated the protocol specs.
4495 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4496 in the network about change in the current ban list. The notify
4497 type is not used by the client.
4499 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4500 support the invite lists.
4502 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added new function silc_string_regexify that converts string
4505 including wildcard characters into regex string that can
4506 be used by the GNU regex library. Added into the file
4507 lib/silcutil/silcutil.[ch].
4509 Added silc_string_regex_combine to combine to regex strings
4510 into one so that they can be used as one regex string by
4511 the GNU regex library. Added into the file
4512 lib/silcutil/silcutil.[ch].
4514 Added silc_string_regex_match to match two strings. It returns
4515 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4517 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Imported GNU regex to the soruce tree into lib/contrib.
4520 Fixed some compiler warning from the regex.c.
4522 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed MOTD command in the server to work in router environment.
4526 * Fixed the MOTD command in the client library to support
4527 the server argument in the command.
4529 * Added `nickname_len' argument to the silc_idlist_add_client
4530 in the server, as the `nickname' argument may be binary data
4533 * Added silc_idlist_get_channels to return all channels from
4536 * Implemented LIST command to the server. Affected file is
4539 * Implemented the LIST command to the client library and on the
4542 * Added [<user count>] argument to the LIST command reply.
4543 With private channels the user count is not shown.
4545 * Updated TODO and README.
4547 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * The client entry's data.registered must be TRUE even with
4550 global client entry on global client list. The data.registered
4551 is used to check whether the client is anymore in the network,
4552 for example with WHOWAS command so it must be valid.
4554 * Fixed the WHOWAS command in the server. It now actually works
4555 in router environment. Added function into silcd/command_reply.c
4556 silc_server_command_reply_whowas_save.
4558 * Added silc_idlist_purge function to the silcd/idlist.c
4559 to periodically purge the ID Cache.
4561 * Fixed INFO command in the server. It works now in router
4562 environment. Added <server name> argument to the INFO command
4563 reply. Updated the protocol specs.
4565 * Fixed minor bug in silc_idcache_purge to not purge if the
4566 expire value is zero.
4568 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4569 they were buggy because of the WHOWAS information.
4571 * Fixed local command MSG to handle the async resolving of
4572 the remote client properly. It used to fail the first MSG.
4573 Affected file silc/local_command.c.
4575 * Added `data_len' field to SilcIDCache context.
4577 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Update TODO. Todo in commands in the server.
4581 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4584 used by routers as broadcast packet to inform other routers
4585 about the changed user mode.
4587 Implemented the notify handling in the server. Affected file is
4588 silcd/packet_receive.c. Added the function
4589 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4591 * Added new generic Channel Payload and deprecated the New Channel
4592 Payload. The New Channel Payload is now the generic Channel
4595 * Added new argument `mode' to the silc_server_send_new_channel
4596 as it is required in the Channel Payload now.
4598 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4599 and created a new and real SilChannelPayload to represent the
4600 new generic Channel Payload. Implemented the encode/decode
4601 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4603 * Added silc_server_get_client_channel_list to return the list
4604 of channels the client has joined for WHOIS command reply.
4605 Affected file silcd/server.[ch].
4607 * Implemented the channel list sending in the WHOIS command reply
4608 in server and in the client.
4610 Implemented the channel list displaying on the user interface
4611 as well. Affected file silc/client_ops.c.
4613 * Added silc_channel_payload_parse_list to parse list of Channel
4614 Payloads. It returns SilcDList list of SilcChannelPayloads.
4615 Client for example can use this function to parse the list of
4616 channels it receives in the WHOIS command reply. The caller
4617 must free the list by calling silc_channel_payload_list_free.
4618 Affected files lib/silccore/silcchannel.[ch].
4620 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added one new argument <user mode> to the WHOIS command reply
4623 to return the mode of the user in SILC. Updated the protocol
4626 Implemented it to the server and client.
4628 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Fixed the mode printing on the user interface on joining.
4631 Affected file silc/client_ops.c.
4633 * Implemented the UMODE command and user modes in general to the
4634 client library and to the user interface.
4636 * Implemented the UMODE command to the server.
4638 * The server now sends UNKNOWN_COMMAND error status if client sends
4639 unknown command. Affected file silcd/command.c.
4641 * All server commands now handle the command identifier the right
4642 way when sending the command reply to the client. The client can
4643 use to identify the command replies with the identifier.
4645 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Added silc_server_get_client_route to resolve the route to
4648 the client indicated by the client ID. Affected file is
4651 * Added silc_server_relay_packet as general function to relay
4652 packet to arbitrary destination. This deprecates functions
4653 like _send_private_message_key, _relay_notify etc. Affected
4654 file is silcd/packet_send.[ch].
4656 Removed silc_server_send_key_agreement,
4657 silc_server_send_private_message_key and
4658 silc_server_packet_relay_notify functions from the file
4659 silcd/packet_send.[ch].
4663 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4664 server. Affected file silcd/packet_receive.[ch].
4666 * Implemented the KILL command to the client. Implemented the
4667 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4668 Affected files lib/silcclient/command[_reply].c and
4669 lib/silcclient/client_notify.c. Implemented the KILL notify
4670 printing in the user inteface.
4672 * Fixed a lot silc_parse_nick memory leaks from the client
4673 library in the file lib/silcclient/command.c.
4675 * Changed the silc_server_send_notify_on_channels's `sender'
4676 argument from SilcSocketConnection to SilcClientEntry to
4677 check the sender as entry and not as connection object and not
4678 to send to the client provided as argument. The affected file
4679 is silcd/packet_send.[ch].
4681 * The notify packets that are destined directly to the client used
4682 to not to be processed by the server. Now changed that and the
4683 server processes all notify packets. After relaying the packet
4684 to the client the notify packet is processed in the server.
4686 * The silc_server_free_client_data now checks whether there is
4687 pending outgoing traffic for the client and purges the data to
4688 the network before removing the client entry.
4690 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4693 an client is killed from the SILC Network. Updated the protocol
4696 Added new function silc_server_send_notify_killed to the
4697 silcd/packet_send.[ch].
4699 * Added function silc_server_packet_relay_notify to relay notify
4700 packets that are destined directly to a client. In this case
4701 the server does not process the notify packets but merely relays
4702 it to the client. Affected file silcd/packet_send.[ch].
4704 Added also silc_server_packet_process_relay_notify to check
4705 whereto relay the notify. Affected file is
4706 silcd/packet_receive.[ch].
4708 * Implemented the KILL command to the server.
4712 * Added the backup schema desgined last fall to the protocol
4713 specs for everyone to see. The specification is in the
4714 *-spec-xx.txt draft and the packet type definitions for the
4715 backup routers is in *-pp-xx.txt draft. Thusly, added also
4716 new packet type SILC_PACKET_CELL_ROUTERS.
4718 * A big security problem in the implementation discovered. The
4719 signoff of an client did not cause new channel key generation
4720 which it of course should've done. The channel keys must be
4721 always re-generated when client leaves (or signoffs) the channel.
4722 The silc_server_remove_from_channels funtion now handles
4723 the channel key re-generation.
4725 * Added `sender' argument to the silc_server_send_notify_on_channels
4726 to not to send the client provided as argument. Affected file
4727 silcd/packet_send.[ch].
4729 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Implemented OPER and SILCOPER commands into the server and
4734 * Added silc_auth_verify and silc_auth_verify_data to verify
4735 the authentication directly from the authentication payload.
4736 It supports verifying both passphrase and public key based
4737 authentication. Affected file lib/silccore/silcauth.[ch].
4739 * Added `hash' field to the SilcIDListData structure. It is the
4740 hash negotiated in the SKE protocol. Affected file is
4743 * Slight redesigning of the SilcAuthPayload handling routines.
4744 Do not send SilcPKCS but SilcPublicKey as argument.
4746 * Implemented the public key authentication support to the
4747 serverconfig. The public key is loaded from the provided path
4748 and saved as authentication data to void * pointer. Thus,
4749 changed the unsigned char *auth_data to void *auth_data;
4751 * Fixed SHUTDOWN command to send the reply before the server
4752 is shutdown. :) Affected file silcd/command.c.
4754 * Fixed fatal bug in CONNECT command. The hostname was invalid
4755 memory and server crashed. Affected file silcd/command.c.
4757 * Fixed fatal bug in CLOSE command. The server_entry became
4758 invalid but was referenced later in the command. Affected file
4761 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Fixed fatal bug in failure packet handling. Server ignored
4764 the failure and thus crashed when it came.
4768 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4771 that the command may be executed only once in (about) 2 seconds.
4772 The old SILC_CF_LAG flag is same but allows command bursts up
4773 to five before limiting.
4775 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4776 server code. Various commands now includes the CF_LAG_STRICT
4777 flag to disallow any kind of miss-use of the command.
4779 * Fixed the silc_buffer_unformat to not to allocate any data
4780 if the length of the data is zero. It used to allocate the
4781 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4783 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Changed the format of AdminConnection configuration section
4786 in the server. Added username of the admin to the format.
4787 Affected files silcd/serverconfig.[ch].
4789 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4790 to return admin configuration data by host, username and/or
4793 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Implemented WHOWAS command to the server. Added the functions:
4797 silc_server_command_whowas_parse,
4798 silc_server_command_whowas_send_reply,
4799 silc_server_command_whowas_from_client and
4800 silc_server_command_whowas_from_server
4802 * Added <Client ID> argument to the WHOWAS command reply. Updated
4803 the protocol specs accordingly.
4805 * Implemented WHOWAS command and command_reply to the client
4808 Implemented the WHOWAS printing on the user interface.
4810 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Added new argument to the WHOWAS command reply, the real name.
4813 It is an optional argument. Updated the protocol specs.
4815 * Added SilcIDCacheDestructor callback that is registered when
4816 the SilcIDCache is allocated. The callback is called when
4817 an cache entry in the ID Cache expires, or is purged from the
4818 cache. Added into lib/silccore/idcache.[ch].
4820 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4821 to destruct the client entries when the cache entry expires.
4822 Other ID Cache's in server and in the client library ignores
4825 * If the ID Cache entry's `expire' field is zero then the entry
4826 never expires. Added boolean `expire' argument to the
4827 silc_idcache_add function in the lib/silccore/idcache.[ch].
4828 If it is TRUE the default expiry value is used.
4830 * Added silc_server_free_client_data_timeout that is registered
4831 when client disconnects. By default for 5 minutes we preserve
4832 the client entry for history - for WHOWAS command.
4834 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added support to the server to enforce that commands are not
4837 executed more than once in 2 seconds. If server receives
4838 commands from client more frequently, timeout is registered
4839 to process the commands. Affected file silcd/command.c.
4840 Added new function silc_server_command_process_timeout.
4842 * Changed NICK_NOTIFY handling in client library to check that
4843 if the client's nickname was changed, so there is no need to
4844 resolve anything from the server.
4846 * Removed error printing from the WHOIS and IDENTIFY commands.
4847 If error occurs then it is ignored silently in the client library.
4848 The application, however, may map the received error to
4849 human readable error string. The application currently maps
4850 the NO_SUCH_NICKNAME error to string.
4852 * Made the command status message public to the application. Moved
4853 them from lib/silcclient/command_reply.c to
4854 lib/silcclient/command_reply.h. The application can map the
4855 received command status to the string with the
4856 silc_client_command_status_message function.
4858 * Added check to the server to check that client's ID is same
4859 as the Source ID in the packet the client sent. They must
4862 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added dist-bzip hook to the Makefile.am to make bzip2
4865 compressed distributions.
4867 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Server now enforces the maximum length for the nickname and
4870 the channel as protocol specification dictates. 128 bytes for
4871 nickname and 256 bytes for channel name.
4873 * Moved the WHOIS printing to the application. The client libary
4874 does not print out the WHOIS information anymore, the application
4875 must do it. Renamed silc_client_command_reply_whois_print to
4876 the silc_client_command_reply_whois_save.
4878 The client's idle time is also sent to the application now, and
4879 the idle is shown on screen.
4881 * Added silc_client_command_reply_identify_save to save the
4882 received IDENTIFY entries.
4884 * Do not check for channel private keys in message sending and
4885 reception if the channel does not have the PRIVKEY mode set.
4886 Affected file lib/silclient/client_channel.c.
4888 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4891 just surfaced after chaning the JOIN procedure.
4893 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Added silc_client_get_clients_by_list to get client entries
4896 from Client ID list, that is returned for example by JOIN
4897 and USERS command replies. The application should use this
4898 function for example when JOIN command reply is received to
4899 resolve the clients already on the channel (library does not
4900 do that anymore as USERS command reply is not used in the JOIN
4901 procedure anymore). Affected files lib/silcclient/silcapi.h and
4902 lib/silcclient/idlist.c.
4904 * JOIN command reply and USERS command reply returns now SilcBuffer
4905 pointers instead of unsigned char pointers when returning
4906 the client list and mode list.
4908 * Added <Client ID> argument to the JOIN command reply, mainly
4909 for the server to identify for which client the command was
4910 originally sent. Updated protocol specs accordingly.
4912 * Added SilcDlist private_key pointer to the SilcChannelEntry
4913 in the client to support the channel private keys. Affected
4914 file is lib/silcclient/idlist.h.
4916 * Added SilcChannelPrivateKey argument to the function
4917 silc_client_send_channel_message so that application can choose
4918 to use specific private ke if it wants to. If it is not provided,
4919 the normal channel key is used, unless private keys are set.
4920 In this case the first (key that was added first) is used
4921 as the encryption key.
4923 * Implemented the support for channel private key handling.
4924 Implemented the following functions:
4926 silc_client_add_channel_private_key,
4927 silc_client_del_channel_private_keys,
4928 silc_client_del_channel_private_key,
4929 silc_client_list_channel_private_keys and
4930 silc_client_free_channel_private_keys
4932 Affected file lib/silcclient/client_channel.c.
4934 * Added the support for the private keys in the channel message
4935 sending and encryption and in the message reception and
4936 decryption. Affected funtions are
4937 silc_client_send_channel_message and silc_client_channel_message.
4939 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Added SKE's key verify callback to the client library's
4942 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4944 * Removed the statement that server (or router) must send USERS
4945 command reply when joining to the channel so that the client
4946 knows who are on the channel. Instead, the client list and
4947 client's mode list is now sent in the JOIN command reply to the
4948 client who joined channel. This is better solution.
4950 * Added function silc_server_get_users_on_channel and function
4951 silc_server_save_users_on_channel to the silcd/server.[ch].
4953 * Removed function silc_server_command_send_users from the
4956 * Do not show topic on the client library anymore. The topic is
4957 sent in the command reply notify to the application and the
4958 application must show the topic now.
4960 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Added client searching by nickname hash into the IDENTIFY and
4963 WHOIS commands in the server as they were clearly missing from
4964 them. Affected file is silcd/command.c.
4966 * Fixed a bug in private message receiving in the client library.
4967 The remote ID was freed and it wasn't supposed, now it is
4970 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Minor fix to the channel payload; allocate the data area, as it
4973 needs to be of specific length.
4975 * If the key agreement port is zero then the operating
4976 system will define the bound port. Affected files are
4977 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4979 * Added new function silc_channel_payload_decrypt into the file
4980 lib/silccore/silcchannel.[ch].
4982 * Moved the channel message etc, check from silc_packet_decrypt
4983 to applications. The library calls now a generic
4984 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4985 when the packet is either normal or special. This was done to
4986 allow more wide range of checking that was not allowed when
4987 the code was in library. Now applications can do virtually any
4988 checks to the packet and return to the library the decision how
4989 the packet should be processed. Affected files are
4990 lib/silccore/silcpacket.[ch].
4992 Added silc_server_packet_decrypt_check to the server and
4993 silc_client_packet_decrypt_check to the client library.
4995 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4996 to send with specified source and destination information.
4998 * Channel message delivery between routers was broken after the
4999 channel key distribution was fixed earlier. The channel key
5000 was used be to distributed to other routers as well which is not
5001 allowed by the protocol. Now this is fixed and channel keys
5002 really are cell specific and the channel message delivery between
5003 routers comply with the protocol specification.
5005 * Fixed various commands in server to check also the global list
5006 for the channel entry and not just the local list. The affected
5007 file silcd/command.c.
5009 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added assert()s to buffer formatting and unformatting routines
5012 to assert (if --enable-debug) when error occurs. Affected
5013 file: lib/silcutil/silcbuffmt.c.
5015 * Changed to auto-reconnect to check whether the remote host is
5016 router and register the re-connect timeout if it is. It used
5017 to check that whether we are normal server, but router must do
5018 auto-reconnect with another router as well. Affected file
5021 * Removed the [<key len>] option from CMODE command as the cipher
5022 name decides the key length, nowadays. See the defined ciphers
5023 from the protocol specification.
5025 * Added [<hmac>] option to the CMODE command to define the HMAC
5026 for the channel. Added SILC_CMODE_HMAC channel mode.
5028 * Added [<hmac>] option for the JOIN command so that user can
5029 select which HMAC is used to compute the MACs of the channel
5032 * Added Hmac field to the Channel Message Payload. The integrity
5033 of plaintext channel messages are now protected by computing
5034 MAC of the message and attaching the MAC to the payload. The
5035 MAC is encrypted. Now, it is clear that this causes some
5036 overhead to the size of the packet but rationale for this is that
5037 now the receiver can verify whether the channel message decrypted
5038 correctly and also when private keys are set for the channel the
5039 receiver can decrypt the packet with several keys and check from
5040 the MAC which key decrypted the message correctly.
5042 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5043 lib/silccrypt/silccipher.[ch].
5045 * Added silc_hash_len to return the digest length into the
5046 lib/silcrypt/silchash.[ch].
5048 * Rewrote parts of Silc Channel Payload interface in the
5049 lib/silccore/silcchannel.[ch]. The encode function now also
5050 encrypts the packet and parse function decrypts it.
5052 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Fixed a minor formatting bug in the SKE's key material processing.
5055 It actually might have processed the keys wrong way resulting
5058 * Redefined the mandatory HMAC algorithms and added new algorithms.
5059 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5060 and hmac-md5 truncated to 96 bits. The mandatory is now
5061 hmac-sha1-96. Rest are optional (including the one that used
5062 to be mandatory). Rationale for this is that the truncated HMAC
5063 length is sufficient from security point of view and can actually
5064 make the attack against the HMAC harder. Also, the truncated
5065 HMAC causes less overhead to the packets. See the RFC2104 for
5068 * Added new [hmac] configuration section. The SKE used to use
5069 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5070 is of course wrong. The official names that must be proposed in
5071 the SKE are the ones defined in the protocol specification
5072 (hmac-sha1-96 for example). The user can configure any hmac
5073 using any hash function configured in the [hash] section. At
5074 least, the mandatory must be configured.
5076 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5078 * Added HMAC list to the SKE proposal list. It has now both
5079 hash algorithm list and HMAC list. This makes the protocol
5080 incompatible with previous versions. The SKE now seems to work
5081 the way it is supposed to work, for the first time actually.
5083 * Defined plain Hash algorithms to the protocol specification.
5086 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Implemented support for key agreement packets into the server.
5089 Added functions silc_server_key_agreement and
5090 silc_server_send_key_agreement. Other than these functions,
5091 server has nothing to do with this packet.
5093 * Added support for private message key packets into the server.
5094 Added functions silc_server_private_message_key and
5095 silc_server_send_private_message_key.
5099 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5100 called in the protocol's final callback instead in the END
5101 protocol state. This makes a little more sense and in the same
5102 time in client we can use the same protocol routines for normal
5103 key exchange and to key agreement packet handling as well.
5105 * Added to both client's and server's KE protocol context the
5106 SilcSKEKeyMaterial pointer to save the key material. We will
5107 bring the key material to the protocol's final callback by doing
5108 this. The final callback must free the key material.
5110 * Added SKE's packet_send callback into client's KE protocol
5111 context so that the caller can choose what packet sending function
5112 is used. This way we can use different packet sending when
5113 doing normal SKE when doing key agreement packet handling (in
5114 the key agreement packet handling we do not want to encrypt
5117 * Implemented the responder side of the key agreement routines
5118 in the client. The client can now bind to specified port and
5119 accept incoming key negotiation. The key material is passed
5120 to the application after the protocol is over.
5122 * Implemented the processing of incoming Key Agreement packet
5123 in the client. Added function silc_client_key_agreement to
5126 * Implemented the intiator side of the key agreement routines
5127 in the client. The client can now initiate key agreement with
5128 another remote client. The key material is passed to the
5129 application after the protocol is over.
5131 * Created client_keyagr.c to include all the key agreement
5134 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5135 SILC_TASK_CALLBACK except that it is not static.
5137 * Created client_notify.c and moved the Notify packet handling
5138 from the client.[ch] into that file.
5140 * Created client_prvmsg.c and moved all private message and
5141 private message key routines from the client.[ch] into that file.
5143 * Create client_channel.c and moved all channel message and
5144 channel private key routines from the client.[ch] into that file.
5146 * Changed silc_client_get_client_by_id_resolve to resolve with
5147 WHOIS command instead of IDENTIFY command, in the file
5148 lib/silclient/idlist.c.
5150 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Implemented the SKE's responder side to the Client library.
5154 * When FAILURE is received to the protocol do not trust it
5155 blindly. Register a timeout to wait whether the remote closes
5156 the connection as it should do it, only after that process the
5157 actual failure. This was changed to both client and server.
5159 * Added client_internal.h to include some of the structures
5160 there instead of client.h in lib/silcclient/.
5162 * Added function silc_task_unregister_by_callback to unregister
5163 timeouts by the callback function.
5165 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Some "Incomplete WHOIS info" errors has been appearing on the
5168 log files. Took away the entry->userinfo check from WHOIS
5169 reply sending. The entry->userinfo is now " " if client did not
5170 provide one. I thought this was fixed earlier but something
5171 is wrong still. Let's see if the error still appears.
5173 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Fixed a minor bug in the login when the channel key is
5176 re-generated in the server. It used to generate the key in
5177 wrong order and thus caused problems in the channel traffic.
5179 * Fixed a minor bug in channel key distsribution after
5180 KICK command. The key was not sent to the router even though
5183 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added silc_ske_process_key_material_data as generic routine
5186 to process any key material as the SILC protocol dictates. The
5187 function is used by the actual SKE library but can be used by
5188 applications as well. This relates to the private message keys
5189 and the channel private keys since they must be processed the
5190 same way the normal SILC session keys. The protocol dictates
5191 this. Affected files: lib/silcske/silcske.[ch].
5193 Added also silc_ske_free_key_material to free the
5194 SilcSKEKeyMaterial structure.
5196 * Defined silc_cipher_set_key function to set the key for
5197 cipher without using the object's method function. The affected
5198 files: lib/silccrypt/silccipher.[ch].
5200 * Implemented silc silc_client_add_private_message_key,
5201 silc_client_add_private_message_key_ske,
5202 silc_client_del_private_message_key,
5203 silc_client_list_private_message_keys and
5204 silc_client_free_private_message_keys functions in the
5207 Added functions silc_client_send_private_message_key to send
5208 the Private Message Key payload and silc_client_private_message_key
5209 to handle incoming Private Message Key payload.
5211 * Added Cipher field to the Private Message Key payload to set
5212 the cipher to be used. If ignored, the default cipher defined
5213 in the SILC protocol (aes-256-cbc) is used.
5215 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Removed lib/silcclient/ops.h file.
5219 Redefined parts of the SILC Client Library API. Created new
5220 file silcapi.h that deprecates the ops.h file and defines the
5221 published Client Library API. Defined also private message key
5222 API and channel private key API into the file.
5224 This is the file that the application must include from the
5225 SILC Client Library. Other files need not be included by
5226 the application anymore.
5228 * Added new key_agreement client operation callback and also
5229 defined the Key Agreement library API for the application.
5231 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5234 is used by clients to request key negotiation between another
5235 client in the SILC network. If the negotiation is started it
5236 is performed using the SKE protocol. The result of the
5237 negotiation, the secret key material, can be used for example
5238 as private message key.
5240 Implemented the Key Agreement payload into the files
5241 lib/silccore/silauth.[ch].
5243 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Redefined ciphers for the SILC protocol. Added some new ciphers
5246 and defined the key lengths for the algorithms. Changed the
5247 code accordingly. The default key length is now 256 bits.
5249 * Fixed SKE key distribution function silc_ske_process_key_material
5250 when the key length is more than 128 bits. The default key
5251 length in SILC is now 256 bits.
5253 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5254 to indicate unsupported algorithm.
5256 * Renamed rijndael.c to aes.c and all functions as well.
5258 * Fixed a long standing channel key setting bug in client library.
5259 Weird that it has never surfaced before.
5261 * Fixed bug in channel deletion. If the entire channel is removed
5262 then it must also delete the references of the channel entry
5263 from the client's channel list as the client's channel entry and
5264 the channel's client entry share same memory.
5266 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Implemented CONNECT and SHUTDOWN commands in the client.
5270 * Implemented CLOSE command to the client.
5272 * Added the function silc_idlist_find_server_by_name into the
5273 files silcd/idlist.[ch].
5275 Added the function silc_idlist_find_server_by_conn into the
5276 files silcd/idlist.[ch].
5278 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * DIE command was renamed to SHUTDOWN. Updated the both code
5283 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5284 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5286 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5289 * Added function silc_server_create_connection function to create
5290 connection to remote router. My server implementation actually
5291 does not allow router to connect to normal server (it expects
5292 that normal server always initiates the connection to the router)
5293 so the CONNECT command is only good for connecting to another
5296 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5299 or some other client was kicked from the channel.
5301 Implemented the handling of the notify type to both client
5304 Implemented silc_server_send_notify_kicked to send the KICKED
5305 notify. It is used to send it to the server's primary router.
5307 * Implemented the KICK command into server and client.
5309 * Added `query' argument to the silc_idlist_get_client function
5310 to indicate whether to query the client from server or not if
5313 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5314 to indicate that the client is not channel founder.
5318 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Removed the rng context from SilcPacketContext structure and
5321 changed that the packet routine uses the Global RNG API.
5323 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Added support for quit message that client can "leave" on the
5326 channel when it quits the SILC. It is ditributed inside the
5327 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5329 Added silc_server_free_client_data that will take the
5330 signoff message as argument.
5332 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5334 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Updated parts of the protocol specification to keep it up
5339 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5342 payloads in one packet.
5344 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5345 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5346 use now the new List flag.
5348 * Also deprecated the following packet types: REPLACE_ID,
5349 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5351 * Added list support for Notify packet in server.
5353 * Added silc_server_send_notify_channel_change to send the
5354 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5355 the silc_server_send_replace_id.
5357 * Added silc_server_send_notify_nick_change to send the
5358 NICK_CHANGE notify type. Deprecates the function
5359 silc_server_send_replace_id.
5361 * Added silc_server_send_notify_join to send the JOIN notify type.
5362 Deprecates the function silc_server_send_new_channel_user.
5364 * Added silc_server_send_notify_leave to send LEAVE notify type.
5365 Deprecates the function silc_server_send_remove_channel_user.
5367 * Added silc_server_send_notify_cmode and
5368 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5369 types. Deprecates the silc_server_send_set_mode function.
5371 * Added SERVER_SIGNOFF notify type to indicate that server has
5372 quit. This means that all clients on the channel from that
5373 server will drop. This can be also used when netsplit happens.
5375 Deprecated REMOVE_ID packet type since it is not needed anymore
5378 Added silc_server_send_notify_server_signoff to send the
5379 SERVER_SIGNOFF notify type. Deprecates the function
5380 silc_server_send_remove_id.
5382 Added also silc_server_send_notify_signoff to send the
5383 SIGNOFF notify type.
5385 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5386 SILC protocol from this day on. Changed the protocol
5387 specification as well.
5389 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5390 notify type. It is used between routers to notify about
5391 topic changes on a channel.
5393 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5396 * Partly updated the protocol specification to comply with the
5397 changes now made. It is still though a bit outdated.
5399 * The JOIN notify type now takes one extra argument <Channel ID>.
5400 The packet used to be destined to the channel but now the
5401 JOIN type may be sent as list thus it is impossible to
5402 destine it to any specific channel. By adding this argument
5403 it is again possible.
5405 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added CREDITS file. The CHANGES and CREDITS file will appear
5408 in the distribution as well.
5410 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5413 types in the server's silcd/packet_receive.c.
5415 * Implemented CMODE and CUMODE to work in router environment.
5417 * Fixed minor encoding and decoding buglet from the
5418 lib/silccore/silcmode.c.
5420 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5423 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5425 * Changed all SilcConfigServer* and silc_config_server* to
5426 SilcServerConfig* and silc_server_config*, respectively.
5429 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Associated the ID (client or server ID) to the Authentication
5432 Payload to avoid any possibility of forging. Updated the
5433 protocol specification and the code accordingly.
5435 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * The RSA key length is now save to the RsaKey context in the
5438 key generation process in lib/silccrypt/rsa.c. The key length
5439 is now used to figure out the maximum size of the block allowed
5440 to be encrypted/signed.
5442 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5443 is equivalent to the silc_mp_mp2bin but does not allocate any
5446 * Changed silc_mp_mp2bin API to take length argument. If it is
5447 non-zero then the buffer is allocated that large. If zero, then
5448 the size is approximated using silc_mp_sizeinbase, which however
5451 * Created Global RNG API which is global RNG that application can
5452 initialize. After initializing, any routine anywhere in the
5453 code (including library) can use RNG without allocating a new
5454 RNG object. This was done to allow this sort of use of the
5455 RNG in code that has no chance to allocate RNG object. All
5456 applications currently allocate this and many routines in the
5457 library use this. Affected file lib/silccrypt/silcrng.[ch].
5459 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5460 it to use the Global RNG API.
5462 * Defined Authentication Payload into protocol specification that
5463 is used during SILC session to authenticate entities. It is
5464 used for example by client to authenticate itself to the server
5465 to obtain server operator privileges.
5467 Implemented this payload into the lib/silccore/silcauth.[ch].
5468 Implemented also routines for public key based authentication
5469 as the new protocol specification dictates.
5471 Moved definitions of different authentication methods from
5472 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5474 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5475 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5476 silc_pkcs_verify_with_hash functions into the file
5477 lib/silccrypt/silcpkcs.[ch].
5479 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * The client entry's userinfo pointer must be always valid.
5482 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5483 will fail since it requires the userinfo. Now, the userinfo
5484 is allocated as "" if actual userinfo does not exist. Actually,
5485 it must exist and it is totally Ok to drop client connections
5486 that does not announce the userinfo. However, we will make
5487 this workaround for now.
5489 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5490 to return the remote port by socket.
5492 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5495 SILC_SERVER_PENDING_EXEC and added an new macro
5496 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5497 data or when error occurs while processing the pending command.
5499 Added new argument `destructor' into silc_server_command_pending
5500 and to the SilcServerCommandPending object. This destructor is
5501 now called after calling the pending callback or if error occurs
5502 immediately. If error occurs the actual pending callback won't
5503 be called at all - only the destructor. The destructor may be
5504 NULL if destructor is not needed.
5506 All this applies for client library code as well. Similar
5507 changes were made there as well for the pending commands.
5509 In the client, the application must now allocate the
5510 SilcClientCommandContext with the silc_client_command_alloc
5513 * Added reference counter to the SilcServerCommandContext. Added
5514 function silc_server_command_alloc and silc_server_command_dup
5517 Same type of functions added to the client library for the same
5520 * Removed the cmd_ident from IDListData away since it is now
5521 global for all connections. It is the command identifier used
5522 in command sending and with pending commands. The affected file
5525 * Added reference counter to the SilcSocketConnection objecet to
5526 indicate the usage count of the object. The object won't be
5527 freed untill the reference counter hits zero. Currently only
5528 server uses this, and client ignores it. The client must be
5529 set to use this too later. The affected files are
5530 lib/silccore/silcsockconn.[ch]. Added also the function
5531 silc_socket_dup to increase the reference counter.
5533 This was mainly added because it is possible that the socket
5534 is removed underneath of pending command or other async
5535 operation. Now it won't be free'd and proper DISCONNECTING
5536 flags, etc. can be set to avoid sending data to connection that
5537 is not valid anymore.
5539 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5540 the connection. After that it sets SILC_SET_DISCONNECTED.
5541 It is, however, possible that the socket data is not still freed.
5542 The silc_server_packet_process now checks that data is not
5543 read or written to connection that is DISCONNECTED. The socket
5544 get's freed when the reference counter hits zero.
5546 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Changed the client operation API: channel_message operation's
5549 `sender' is now the client entry of the sender, not the nickname
5550 and the `channel' is the channel entry, not the channel name.
5552 In the private_message operation the `sender' is now also the
5553 client entry of the sender not the nickname.
5555 Affected file is lib/silcclient/ops.h and all applications
5556 using the client operations.
5558 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Moved the calling of ops->connect() from connect_to_server_final
5561 into receive_new_id functin since that is the point when the
5562 client is actually allowed to send traffic to network. The
5563 affected file is lib/silcclient/client.c.
5565 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5568 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5569 (if needs broadcasting) instead of broadcasting the packets one
5570 by one which would make a burst in the network traffic.
5572 * Added `broadcast' argument to the functions in silcd/server.[ch]
5573 silc_server_create_new_channel[_with_id] to indicate whether
5574 to send New Channel packet to primary router.
5576 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added new function into the silcd/server.[ch] files:
5579 silc_server_create_new_channel_with_id to create new channel with
5580 already existing Channel ID.
5582 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5583 lib/silccore/silcpacket.h. This packet is used t send list of
5584 Set Mode payloads inside one packet. Server uses this to set
5585 the modes for the channels and clients on those channels, that it
5586 announced to the router when it connected to it. The protocol
5587 specification has been updated accordingly.
5589 * The silc_server_new_channel did not handle the packet coming
5590 from normal server as it normally does not send that. However,
5591 when it announces its channels it does send it. Implemented
5592 the support for that.
5594 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5595 into the file lib/silccore/id.h.
5597 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Fixed memory leaks in the functions silc_idlist_del_client,
5600 silc_idlist_del_channel and silc_idlist_del_server in the file
5601 silcd/idlist.c. All of those leaked like a sieve.
5603 * Fixed some small memory leaks in the client's function
5604 silc_client_notify_by_server.
5606 * Added functions into silcd/server.c: silc_server_announce_clients,
5607 silc_server_announce_channels and silc_server_announce_server.
5608 These functions are used by normal and router server to announce
5609 to its primary router about clients, channels and servers (when
5610 router) that we own. This is done after we've connected to the
5613 These functions effectively implements the following packet types:
5614 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5615 and SILC_PACKET_NEW_ID_LIST.
5617 * Added new functions into the silcd/packet_receive.[ch]:
5618 silc_server_new_id_list, silc_server_new_channel_list and
5619 silc_server_new_channel_user_list to handle the incoming
5620 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5622 * Added support of changing Channel ID in the function
5623 silc_server_replace_id. If the server that announces a channel
5624 to the router already exists in the router (with same name but
5625 with different Channel ID), router is responsible to send
5626 Replace ID packet to the server and force the server to change
5627 the Channel ID to the one router has.
5629 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5630 client that the Channel ID has been changed by the router. The
5631 normal server sends this to the client. Client must start using
5632 the new Channel ID as the channel's ID.
5634 Implemented handling of this new type into lib/silcclient/client.c
5635 into the function silc_client_notify_by_server.
5637 * Added new function silc_idlist_replace_channel_id into the files
5638 silcd/idlist.[ch] to replace the Channel ID.
5640 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Call silc_server_command_identify_check always when processing
5643 the IDENTIFY command in silcd/command.c
5645 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5648 send keepalive packets. The packet can be sent by clients,
5649 servers and routers.
5651 Added function silc_socket_set_heartbeat into the file
5652 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5653 If not set, the heartbeat is not performed. The actual
5654 heartbeat is implemented in the low level socket connection
5655 library. However, application is responsible of actually
5658 Added silc_server_send_heartbeat to send the actual heartbeat
5659 packet into silcd/packet_send.[ch]. Server now performs
5660 keepalive with all connections.
5662 * Added silc_task_get_first function into lib/silcutil/silctask.c
5663 to return the timeout task with shortest timeout. There was a bug
5664 in task unregistration that caused problems. TODO has been
5665 updated to include that task system must be rewritten.
5667 * The client library will now resolve the client information when
5668 receiving JOIN notify from server for client that we know but
5669 have incomplete information.
5671 * Rewrote parts of silc_server_remove_from_channels and
5672 silc_server_remove_from_one_channel as they did not remove the
5673 channel in some circumstances even though they should've.
5675 * Encryption problem encountered in server:
5677 The LEAVE command used to send the Channel Key packet to the
5678 router immediately after generating it. However, the code
5679 had earlier sent Remove Channel user packet but not immediately,
5680 ie. it was put to queue. The order of packets in the router
5681 was that Channel Key packet was first and Remove Channel User
5682 packet was second, even though they were encrypted in the
5683 reverse order. For this reason, MAC check failed. Now, this
5684 is fixed by not sending the Channel Key packet immediately but
5685 putting it to queue. However, this is more fundamental problem:
5686 packets that are in queue should actually not be encrypted
5687 because packets that are sent immediately gets encrypted
5688 actually with wrong IV (and thus MAC check fails). So, packets
5689 that are in queue should be encrypted when they are sent to
5690 the wire and not when they put to the queue.
5692 However, the problem is that the current system has not been
5693 designed to work that way. Instead, the packet is encrypted
5694 as soon as possible and left to the queue. The queue is then
5695 just purged into wire. There won't be any fixes for this
5696 any time soon. So, the current semantic for packet sending
5699 o If you send packet to remote host and do not force the send
5700 (the packet will be in queue) then all subsequent packets to the
5701 same remote host must also be put to the queue. Only after the
5702 queue has been purged is it safe again to force the packet
5705 o If you send all packets immediately then it safe to send
5706 any of subsequent packets through the queue, however, after
5707 the first packet is put to queue then any subsequent packets
5708 must also be put to the queue.
5710 Follow these rules and everything works fine.
5712 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Added new function silc_server_remove_clients_by_server to
5715 remove all client entries from ID list when the server connection
5716 is lost. In this case it is also important to invalidate all
5717 client entires as they hold the invalid server entry. This
5718 fixes fatal bug when server has lost connection and will reconnect
5721 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Made some sanity checks to silc_server_daemonise like to check
5724 whether the requested user and group actually exists.
5726 * Added sanity check to SKE's silc_ske_responder_finish to check
5727 that the public and private key actually is valid.
5729 * Invalidate the client's nickname when receiving Replace ID
5730 packet and the Client ID is being replaced. This means that the
5731 server will query the nickname if someone needs it (client)
5734 * Sort the ID Cache in client library when the ID Cache data
5735 has changed (needs sorting).
5737 * Do not allow for SILC client to create several connections to
5738 several servers. The client does not support windows right now
5739 and generating multiple connections causes weird behaviour.
5741 Irssi-silc client does support windows and can handle several
5742 connections without problems, see: www.irssi.org and SILC plugin.
5744 * Fixed some places where client was added to the IDList. The
5745 rule of thumb is following (in order to get everything right):
5746 If the client is directly connected local client then the
5747 `connection' argument must be set and `router' argument must be
5748 NULL to silc_idlist_add_client function. If the client is not
5749 directly connected client then the `router' argument must
5750 bet set and the `connection' argument must be NULL to the
5751 silc_idlist_add_client function.
5753 * The funtion silc_server_packet_send_local_channel actually did
5754 not check whether the client was locally connected or not. It
5755 does that now. Fixed a bug related to LEAVE command.
5757 * Fixed Remove Channel User payload parsing bug in server's
5758 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5760 * The server's silc_server_save_channel_key now checks also the
5761 global ID list for the channel as it might not be in the local
5762 list. Fixed a bug related to LEAVE command.
5764 * Is this the end of the [<unknown>] buglet that has been lurking
5765 around for a long time? A little for loop fix in server's
5766 silc_server_command_whois_parse that is used by both IDENTIFY
5767 and WHOIS command. At least, this was a clear bug and a cause
5768 of one type of [<unknown>] buglet.
5770 * WHOIS and IDENTIFY commands call the function
5771 silc_server_command_[whois/identify]_check function even if
5772 we are not router server.
5774 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Added --with-gmp configuration option. If set the GMP
5777 is always compiled in the SILC source tree. If not set then
5778 it is checked whether the system has the GMP3 installed. If
5779 it has then the GMP won't be compiled (the system's headers
5780 and library is used), if it doesn't have it then the GMP is
5781 compiled in the SILC source tree.
5783 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Changed RSA private exponent generation to what PKCS #1
5786 suggests. We try to find the smallest possible d by doing
5787 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5788 not security fix but optimization.
5790 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added new config entry [Identity] to fork the server and run
5793 it as specific user and group. A patch from Bostik.
5795 * Imported Dotconf configuration library into lib/dotconf.
5796 This will be used to create the SILC configuration files later.
5797 It will appear in the distsribution after this commit.
5799 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * A big code auditing weekend happening. Auditing code for
5802 obvious mistakes, bugs and errors. Also, removing any code
5805 Removed files for being obsolete:
5807 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5808 inline in the file lib/silcutil/silcbuffer.h)
5810 o lib/silcutil/silcbufutil.c (the header has inline versions)
5812 Changed code to fix possible error conditions:
5814 o The buffer formatting routines now check that the destination
5815 buffer really has enough space to add the data. This applies for
5816 both buffer formatting and unformatting
5817 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5818 unformatting was changed to accomodate following rules:
5819 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5820 sent to the function while XXX_*STRING will not allocate or copy
5821 the data into the buffer. Instead it sets the pointer from the
5822 buffer into the pointer sent as argument (XXX_*STRING used to
5823 require that the pointer must be allocated already). This change
5824 makes this whole thing a bit more consistent and more optimized
5825 (note that the data returned in the unformatting with XXX_*STRING
5826 must not be freed now). The routines return now -1 on error.
5828 o Tried to find all code that use buffer_format and buffer_unformat
5829 and added return value checking to prevent formatting and
5830 especially unformatting errors and possible subsequent fatal
5833 o Changed ske->x and ske->KEY to mallocated pointers in
5834 lib/silcske/silcske.h. Fixed possible data and memory leak.
5836 o Added return value checking to all *_parse* functions. Fixed
5837 many memory leaks as well.
5839 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5840 so that buffer overflows would not happen. All code now also
5841 checks the return value as it can fail.
5843 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added reconnection support to server if the normal server looses
5846 its connection to the router (for example if router is rebooted).
5847 The server performs normal reconnection strategy implemented
5848 to the server. Affected file silcd/server.c.
5850 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Added new packet type SILC_PACKET_SET_MODE that is used to
5853 distribute the information about changed modes (for clients,
5854 channels and clients channel modes) to all routers in the
5855 network. Updated the protocol specification accordingly.
5857 Added functions into silcd/packet_send.c and
5858 silcd/packet_receive.c: silc_server_send_set_mode,
5859 silc_server_set_mode.
5861 Added new files silcmode.[ch] into lib/silccore that implements
5862 the encoding and decoding of Set Mode Payload. Added new type
5863 SilcSetModePayload. Moved the definitions of different modes
5864 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5866 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Oops, a little mistake in server's connection authentication
5869 protocol. The protocol is not ended with FAILURE but with
5870 SUCCESS if the authentication is Ok. :) Affected file is
5873 * Implemented NICK_CHANGE notify handling in server in the file
5874 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5875 the local clients on the channel. After the changing nickname
5876 in router environment snhould work and the [<unknown>] nickname
5877 should appear no more.
5879 The silc_server_replace_id function that receives the Replace ID
5880 payload now sends the NICK_CHANGE notify type also in the file
5881 silcd/packet_receive.c
5883 * Changed WHOIS and IDENTIFY command to support the maximum amount
5884 of arguments defined in protocol specs (3328 arguments). This
5885 fixed a bug that caused problems when there were more than three
5888 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Added extra parameter, command identifier, to the
5891 silc_client_send_command so that explicit command identifier
5894 Changed that ID list routines uses specific command identifier
5895 when sending WHOIS/IDENTIFY requests to the server so that they
5896 can be identified when the reply comes back.
5898 Affected files lib/silcclient/command.[ch],
5899 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5901 * Added `sender' argument to silc_server_packet_send_to_channel
5902 to indicaet the sender who originally sent the packet to us
5903 that we are now re-sending. Ignored if NULL. Affected file
5904 silcd/packet_send.[ch].
5906 * Added some server statistics support in silcd/server_internal.h
5907 SilcServerStatistics structure and around the server code. Also
5908 send some nice statistics information when client is connecting
5911 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed channel ID decoding in server's JOIN command reply in
5914 silcd/command_reply.c
5916 * Fixed braodcasting of replace ID payload to not to send it if
5917 we are standalone server in silcd/packet_receive.c.
5919 * Fixed all channel message sending routines to not to send
5920 packets to clients that has router set, since they are routed
5921 separately in the same function earlier. Affects file
5922 silcd/packet_send.c and all channel packet sending functions.
5924 * In USERS reply, res_argv[i] are not allocated, the table
5925 is allocated. Thus changed that free the table, not its
5928 * In server's whois_check and identify_check if the client is
5929 locally connected do not send any WHOIS commands - they are not
5932 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Fixed some minor bugs in client when sending WHOIS command. The
5935 arguments was in wrong order.
5937 * Removed statis function add_to_channel from server in
5938 silcd/command.c that was previously used with the joining but
5941 * Tested USERS command in router environment successfully with two
5942 routers, two servers and two clients.
5944 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Reorganized the USERS command and command reply in client library
5947 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5948 When the command is given by user we register a pending command
5949 callback that will reprocess the command after the reply has been
5950 received from the server. When reprocessing the packet we then
5951 display the information. Thus, the USERS information is displayed
5952 now in the command callback instead of in the command reply
5953 callback. The processing of the command is same as previously
5954 when server has sent the command reply in the JOINing process.
5956 * Added to USERS command in silcd/command_reply.c to join the client,
5957 we didn't use to know about, to the channel after we've created
5958 a client entry for it. Also, for clienet we did know already still
5959 check whether it is on the channel or not and add it if not.
5961 * Removed silc_server_command_join_notify as the function and its
5964 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Changed the client's pending command handling to the same as the
5967 server's pending command handling. It is also now possible to
5968 execute command reply functions from other command reply
5969 function as the function callbacks for commands and command
5970 replies are one and same. The pending commands are not static
5971 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5972 in client connection context. Thus, pending commands are server
5973 connection specific as it is convenient.
5975 Changed the function silc_client_command_pending and
5976 silc_client_command_pending_del and added new function
5977 silc_client_command_pending_check. Removed the
5978 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5981 * Added cmd_ident, current command identifier, to the client
5982 connection context in lib/silcclient/client.h to keep track on
5983 command identifiers used in command sending. Client's command reply
5984 function handling now supports the mandatory command identifiers.
5986 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5987 funtions in client to fully support pending command callbacks.
5989 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5990 as one of the arguments to the application in the command reply
5993 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5994 before first releasing SILC but came back. Now it is removed again
5995 and should come back nomore. The FORWARDED flag was used only
5996 by the JOINing procedure by forwarding the command packet to router.
5997 Now, the JOINing procedure has been changed to more generic (due
5998 to various router environment issues) and FORWARDED is not needed
5999 anymore for anything. The protocol specification is yet to be
6002 Now, removed silc_server_packet_forward from server and the flag
6003 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6005 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Renamed NAMES command to USERS command. The NAMES was named that
6008 due to historical reasons. Now it is renamed. Also, rewrote
6009 parts of the USERS command. The nickname list is not sent anymore
6010 by the server. Only Client ID and mode lists are sent in the USERS
6011 command. Changed this also to the protocol specification.
6013 The client now resolves the names and stuff after it receives
6014 the USERS list from the server when joining to the channel.
6016 * WHOIS and IDENTIFY commands has been changed to support multiple
6017 Client ID's per command. One can now search for multiple users
6018 in the network by sending only one WHOIS or IDENTIFY command.
6019 Changed the code and the protocol specifications.
6021 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6022 uses silc_server_command_whois_parse to parse the request. */
6024 * If normal server, do not parse the WHOIS and IDENTIFY requests
6025 before sending it to the router. Saves some time.
6027 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Fixed JOIN command on client library. Wrong number of arguments
6030 used to crash the client.
6032 * Added silc_server_channel_has_global function to check whether
6033 channel has global users or not.
6035 * Added silc_server_channel_has_local function to check whether channel
6036 has locally connected clients on the channel.
6038 * The silc_server_remove_from_one_channel now checks whether the
6039 channel has global users or not after given client was removed from
6040 the channel. It also checks whether the channel has local clients
6041 on the channel anymore. If it does not have then the channel entry
6042 is removed as it is not needed anymore.
6044 * The silc_server_notify now checks on JOIN notify whether the joining
6045 client is one of locally connected or global. If it is global then
6046 the channel has now global users on the channel and that is marked
6047 to the channel entry. Also, it now saves the global client to
6048 global list who is joining and JOINs it to the channel. This is
6049 for normal server, that is.
6051 Changed silc_server_send_notify_on_channel,
6052 silc_server_packet_relay_to_channel and
6053 silc_server_packet_send_to_channel check if we are normal server
6054 and client has router set (ie. global client) do not send the
6055 message to that client, as it is already routed to our router.
6057 * Implemented LEAVE notify type handling in silc_server_notify
6060 * Tested LEAVE command in router environment successfully. Tested
6061 with two routers, two servers and two clients.
6065 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6067 * Implemented SIGNOFF notify type handling in silc_server_notify
6070 * silc_server_remove_id now removes the client entry from all channels
6071 it has joined and thusly sends SIGNOFF notify type.
6073 * Rewrote the NAMES list generation in server by removing two excess
6074 loops. The lists are created now inside one loop.
6076 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * silc_server_remove_channel_user checks now also global list
6079 for channel and client.
6081 * silc_server_new_channel_user checks now both local and global
6082 list for channel and client. Fixed a bug in client id decoding.
6083 Used to decode wrong buffer.
6085 * silc_server_channel_message checks now both local and global
6086 list for channel entry.
6088 * Tested channel joining (hence JOIN) in router environment
6089 successfully. Tested with two routers, two servers and two
6092 * Tested channel message sending in router environment successfully.
6094 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Added silc_server_save_channel_key into server.[ch] to save the
6097 received channel key in Channel Key payload processing. It is
6098 also used in JOIN command reply handling.
6100 Equivalent function silc_client_save_channel_key added into
6101 client.[ch] into client library.
6103 * Changed JOIN command reply to send information whether the channel
6104 was created or not (is existing already) and the channel key
6105 payload. Changed protocol specs accordingly.
6107 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6108 the request was sent by ID and not by nickname. Crashed on
6111 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6114 now correctly save the received data.
6116 * silc_server_free_sock_user_data now notifies routers in the
6117 network about entities leaving the network.
6119 At the same time implemented functions silc_server_remove_id
6120 and silc_server_send_remove_id to receive and send REMOVE_ID
6121 packets. The packet is used to notify routers in the network
6122 about leaving entities. The ID removed will become invalid in
6125 * Added function silc_idlist_del_server into server. Removes and
6126 free's server entry from ID list.
6128 * silc_server_private_message function now checks, if we are router,
6129 that the destination ID really is valid ID, naturally.
6131 * In router when NEW_ID packet is received (for new client) the
6132 hash of the Client ID is saved in the ID Cache but the
6133 client->nickname is set to NULL, instead of putting the hash
6136 IDENTIFY command now also checks that client->nickname must be
6137 valid. If it is not if will request the data from the server who
6138 owns the client. Added new function
6139 silc_server_command_identify_check.
6141 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6142 to set the command to already allocated Command Payload.
6144 * Tested private message sending in router environment with two
6145 routers, two servers and two clients. Fixed minor bugs and now
6148 * Fixed segfault from client's NAMES command. Used to crash if
6151 * Forwarded packets must not be routed even if it is not destined
6152 to the receiver. Changed server code comply with this.
6154 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Added `require_reverse_mapping' boolean value to ServerParams
6157 structure. If TRUE (not default) the server will require that
6158 the connecting host has fully qualified domain name.
6160 If the reverse mapping is not required and hostname could not be
6161 found the IP address is used as hostname.
6163 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Implemented version string checking to both client and server.
6166 The check is incomplete currently due to the abnormal version
6167 strings used in development version of SILC.
6169 * Changed all command functions in server to use the new
6172 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Changed char *data to unsigned char *data in ID Cache system to
6175 support binary data as ID Cache data. Changed code to support
6176 binary data in lib/silccore/idcache.c.
6178 * Renamed silc_server_packet_relay_command_reply to
6179 silc_server_command_reply as it is normal packet receiving
6180 function. Rewrote the function to accept command replys for
6181 servers and not only for clients.
6183 * Mark remote router always as registered server if we are connecting
6184 to it. Otherwise, commands sent by the router to us are ignored.
6186 * All ID List find routines now returns the ID Cache Entry pointer
6187 as well if requested.
6189 * WHOIS command works now in router environment, tested with two
6190 routers, two servers and two clients.
6192 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6193 in router environment (as it is almost equivalent to WHOIS) but
6194 hasn't been tested thoroughly. Added new functions:
6196 silc_server_command_identify_parse
6197 silc_server_command_identify_send_reply
6198 silc_server_command_identify_from_client
6199 silc_server_command_identify_from_server
6201 * Disabled route cache adding because adding two different ID's with
6202 same IP replaces the old cache entry thus giving wrong route.
6203 The entry->router->connection is always the fastest route anyway
6204 so route cache may not be needed. Of course, new routes maybe
6205 established after receiving the ID when the entry->router->connection
6206 might not be anymore the most optimal.
6208 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Add route cache for received ID for fast routing.
6212 * Added silc_server_packet_route to route received packet on router
6213 that is not destined to us.
6215 * Renamed silc_server_get_route to silc_server_route_get.
6217 * Added id_string and id_string_len fields into SilcServer to
6218 include encoded ServerID for fast comparing without excess
6219 encoding of the ID's.
6221 * Cleaned up WHOIS command on server side. Added following static
6224 silc_server_command_whois_parse
6225 silc_server_command_whois_check
6226 silc_server_command_whois_send_reply
6227 silc_server_command_whois_from_client
6228 silc_server_command_whois_from_server
6230 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6231 arguments in command replies. All command functions should be
6232 updated to use this macro.
6234 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Minor typo fixes on command reply handling on server.
6238 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Added silc_server_command_add_to_channel internal routine to add
6241 the client to the channel after router has created the channel and
6242 sent command reply to the server.
6244 * Added generic silc_server_send_command to send any command from
6247 * Use static buffer with ID rendering instead of duplicating data.
6249 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Fixed a channel user mode bug when joining to a channel server gave
6252 everybody channel founder rights, oops.
6254 * We mark ourselves as the router of the incoming server connection
6255 if we are router ourselves. This way we can check in some packet
6256 sending functions whether it is locally connected server. For
6257 incoming router connections we put NULL.
6259 * For router sending packets locally means now always sending the
6260 packet cell wide; to local clients and local servers. For normal
6261 server sending packet locally means sending it to only local
6264 * Fixed the JOIN command to really work in router environment. If the
6265 channel is created it is always created by the router. Router is
6266 also responsible of making the initial joining to the channel,
6267 sending JOIN notify to the sending server and distributing
6268 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6269 does not exist server doesn't do anything else but forward the
6270 command to the router which performs everything.
6272 * Added silc_server_send_channel_key function to send the Channel Key
6275 * Added silc_server_create_channel_key to create new channel key. The
6276 channel key is now re-generated everytime someone joins or leaves
6277 a channel, as protocol dictates. Note: channel->key_len is the
6280 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6282 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6283 packet_receive.[ch] to separate packet sending and receiving
6284 routines. The server.[ch] now includes everything else including
6285 actual packet processing (writing and reading data) and other
6288 Renamed silc_server_private_message_send_internal to
6289 silc_server_send_private_message. The routine is still though
6290 used only to relay private messages as server does not send
6291 private messages itself.
6293 Renamed silc_server_new_channel to silc_server_create_new_channel
6294 and added new function sicl_server_new_channel that handles the
6295 incoming New Channel packet. Added also new sending function
6296 silc_server_send_new_channel to send New Channel Payload.
6298 * Added new function silc_server_notify to process incoming notify
6299 packet to the server/router. Server may then relay the notify
6300 to clients if needed.
6302 * Added new function silc_server_new_channel_user to process incoming
6303 New Channel User packet. Router will redistribute the packet and
6304 send JOIN notify to its local clients and locally connected servers
6305 if needed. Normal server will send JOIN notify to its local client
6306 on same channel when received this packet. Added also corresponding
6307 sending function silc_server_send_new_channel_user to sent the
6310 * Added boolean route argument to send_notif_to_channel and
6311 packet_send_to_channel functions to attempt to route the packet
6312 if it is TRUE and send only locally if it is FALSE.
6314 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * silc_server_replace_id now broadcasts the received replace ID
6317 packet if it is not broadcast packet already. The router must
6318 broadcast to inform other routers about changed ID.
6320 * Added backpointer to server's router into SilcServer context in
6321 silcd/server_internal.h.
6323 * Fixed silc_server_packet_broadcast to send correct broadcast
6326 * The channel key is now distributed to the local client as soon
6327 as it is received from the router (in router environment) so that
6328 no other packet may be sent for the channel until client has
6331 * silc_server_remove_channel_user now broadcasts the received
6332 Remove Channel User packet if it is not broadcast packet already.
6333 The router must broadcast to inform other routers about removed
6336 * Added users field into SilcPacketContext that is a reference count
6337 of the context. One can increase the reference count by calling
6338 silc_packet_context_dup which is now changed to just increase the
6339 reference count instead of duplicating the data. The reference
6340 count is decresed by calling silc_packet_context_free that will
6341 free the data after the reference count hits zero.
6343 For now on the packet context and everything allocated into it
6344 (including the raw packet from network) must be freed by calling
6345 the new silc_packet_context_free function. Added also new function
6346 silc_packet_context_alloc that must be used now to allocate the
6347 context. This also means that if a routine is asynchronous from
6348 silc_[client/server]_packet_parse_type the packet context must
6349 be duplicated by calling silc_packet_context_dup. Otherwise it
6350 gets free'd after silc_[client/server]_packet_parse_type returns.
6351 Also, one must remember that if packet is duplicated then its
6352 reference count must be decresed by calling the free function as
6353 many times as it was duplicated.
6355 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6356 from both client and server.
6358 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Made joining to a channel working in router environment.
6362 * Cleaned up JOIN command on server side and create function
6363 silc_server_command_join_channel internal routine to make the
6366 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Changed silc_command_pending list to SilcDList. Also, added
6369 `ident' field to SilcServerCommandPending structure to identify
6370 the reply and to call correct callback.
6372 Added silc_server_command_pending_check function to replace the
6373 corresnponding macro. The silc_command_pending list is not
6376 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6377 to set identifier to previously allocated Command Payload. It
6378 is used to set identifier for command when resending Command
6381 * Added silc_command_payload_encode_payload to encode Command
6382 Payload buffer from SilcCommandPayload structure.
6384 * Added silc_argument_payload_encode_payload to encode Argument
6385 payload buffer from SilcArgumentPayload structure.
6387 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Changed WHOIS command to support router connection on server side.
6390 The whois request is always sent to router unless the server is
6391 standalone server. After server has received the reply from the
6392 router will it send the reply to the client.
6394 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6395 broadcast received broadcast packet. The function is used only
6396 by router. The broadcast packet is always sent to the router's
6399 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6400 render given ID to printable string, for log files for example.
6402 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Made basic router to router connections working. At least they
6405 can now connect to each other but nothing really works the way
6406 they are supposed - yet.
6408 * Added new initiator token to RouterConnection configuration
6409 file in silcd/serverconfig.[ch]. It is used to tell whether we
6410 are the initiator to the remote router or whether we'll expect
6411 the other end to connect.
6413 * Moved registering of listener task to silc_server_init, hence
6414 the server starts listenning as soon as it is run, even if it
6415 does not have connections to other routers. Let's see how well
6418 * Changed default connection retry timeouts for more suitable in
6421 * Removed cipher and such arguments from silc_idlist_add_client
6422 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6423 Added new function silc_idlist_add_data to add the keys and stuff
6426 * Added SilcIDListData structure and added it to SilcClientEntry
6427 and SilcServerEntry as their first field in the structure. This
6428 way we can explicitly cast the ID entries to the SilcIDListData
6429 structure and get common data for the entries. In past, we had
6430 to first check what type of connection it is and then cast it to
6431 correct ID entry type. Now, we can directly cast the opaque
6432 pointer to the SilcIDListData (no matter what ID entry it actually
6433 is) and get the data needed.
6435 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6438 in some circumstances even if threre were timeout tasks, though not
6439 IO tasks, but tasks anyway. Now fixed.
6441 * Defined SilcServerConnection structure to hold connection specific
6442 stuff about directly connected servers and routers. The definition
6443 is currently in silcd/server_internal.h. I thought about having
6444 a bit more important role fro this struct but for now it is used
6445 only when connecting to other server (or router actually).
6447 * Added connecting retry support in server when connecting to
6448 router(s). The retry feature implement exponential backoff
6449 algorithm. Also, added SilcServerParams structure to hold default
6450 parameters for server. For now, it include these retry settings
6451 and are hard coded. After server is moded to be as Silc Server
6452 Library this structure will be more important.
6454 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Changed client librarys channel->clients table to SilcList and
6457 changed code accordingly.
6459 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Changed client's channel table to SilcList and changed code
6462 accordingly. Also changed SilcChannelClientEntry to include back-
6463 pointer to the channel so that client entry can use that structure
6464 as list as well and we have fast cross-reference to the channel.
6465 This change dramatically decreased the complexity of channel
6466 handling with client entry and vice versa (removed one extra
6467 loop when searching for channel entry from many functions).
6469 * Changed server->sim from table to SilcDList and changed code
6472 * NAMES command can now be used from user interface. It will show
6473 the user list on the channel, neatly.
6475 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6476 Code now saves realname of the user if it becomes available.
6478 * Renamed configure.in to configure.in.pre and made ./prepare
6479 script to automatically add correct version string to
6480 configure.in which it creates from configure.in.pre.
6482 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * NAMES command reply now shows users mode with the nickname when
6487 * Moved silc_client_ch[u]mode[_char] functions from
6488 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6489 place sucks, they are utility functions and should be in some
6492 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6494 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6497 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added TRQ (efficient deque and list library) into lib/trq. This is
6502 a very good list library that is currently used in the SILC. Defined
6503 SilcList API over the library because I didn't like the API very
6504 much. See lib/trq/silclist.h for the API and examples of how to
6505 use the API. Fixed various places in the code to use the new
6506 SilcList API. The SilcList is meant for lists that has a structure
6507 already defined as a list. It is not suitable to add just some
6508 context to the list (in TRQ, the context is the list actually).
6510 So, I defined SilcDList that can be used for the purpose where
6511 predefined list structure does not exit. This can be used as
6512 such list. Now some context just can be added to the SilcDList.
6513 Currently this list is not used in the SILC just yet, though there
6514 are a lot places where this can replace dynamically allocated
6515 tables and I will fix these places, later, to use SilcDList.
6516 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6517 and use TRQ internally).
6519 Also fixed some annoying warning messages that the original TRQ
6520 code generated. Also minor changes to TRQ's Makefile.in.
6522 * Added support for querying by Client ID to both WHOIS and
6523 IDENTIFY commands into server, as required by the protocol.
6525 * Removed method function pointers from SilcBuffer structure. They
6526 weren't used to anything and just increased the context size for
6527 no good reason. This change also made silc_buffer_alloc and
6528 silc_buffer_free functions inline functions.
6530 * Disabled command flooding detection support until it's fixed so
6531 that it accepts commands in but does not execute them more than once
6534 * Added silc_net_localhost(), to return local hostname, into
6535 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6536 that must be initialized before calling silc_client_init.
6538 * Added new function: silc_server_send_notify_on_channels to send
6539 notify messages to all channels client has joined. It is assured
6540 that the message is sent only once per client.
6542 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6543 lib/silcutil/silcutil.[ch] as silc_format function. The new
6544 function is generic and is used by server as well, not only by
6545 the logging routines.
6547 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6548 the provided version string was not acceptable. Added new function:
6549 silc_ske_check_version into lib/silcske/silcske.h. The function
6550 must be implemented by the application (client or server) and it
6551 does not reside in the SKE library. The function checks the version
6552 string remote end sent.
6554 * Added back pointers (to opaque context and to SilcSocketConnection)
6555 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6557 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6558 duplicate packet context structure.
6560 * Changed `notify' client operation to send same arguments as client
6561 receives from server except for ID's. ID's are mapped to correct
6562 ID entry and that is returned. Also, if channel entry is not sent
6563 by server but the notify is for channel the channel entry is sent
6564 to application (otherwise application doesn't know that it is for
6565 channel (library gets it from packet's Destination ID)).
6567 * Added silc_client_remove_from_channels into client library to
6568 remove a client from all channels it has joined to. Used when
6569 received SIGNOFF notify from server. Added also new function
6570 silc_client_replace_from_channels to replace old ID entry with
6571 new ID entry on all channels. Used when received NICK_CHANGE
6574 * Fixed ID Cache list handling in silc_idlist_get_client in
6575 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6576 to get (or query) client by ID.
6578 * Updated TODO list.
6580 * Added connection authentication status message defined by the
6581 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6582 support for these into the code in client and server side.
6584 * Added generic function silc_client_send_command to send any command
6585 with variable argument list. Application should use this function
6586 to send commands if the command functions provided by the library
6587 does not suite for the application's user interface needs.
6589 * Added new `failure' client operation. Application is notified about
6590 received failure packet if client is executing a protocol. In this
6591 case the protocol's execution has failed.
6593 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6594 is required by the protocol.
6596 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6597 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6600 * Added status flag to SilcSKE object to indicate realtime status
6601 of the SKE protocol.
6603 * Application receives now exactly same command reply arguments as
6604 the library receives from server. However, if ID is received the
6605 corresponding ID entry is returned to the application (eg. Client
6606 ID is mapped to correct SilcClientEntry entry and that is returned).
6607 Changed command_reply client operation due to this change.
6609 * Changed all ID's in commands and in command replys as ID Payloads.
6610 Change affected both client and server side codes.
6612 All ID's sent in SILC network (with execption of ID's in SILC
6613 Packet header) are sent in ID Payload to support variable length
6616 * Server now notifies nick changes and notifies all clients on
6617 the channels about the new nickname (about the new Client ID,
6620 * Implemented CMODE command to change channel modes. Supports all
6621 channel modes defined by the protocol specs except ban and invite
6622 lists. (Also, private channel key mode is supported but support for
6623 setting private channel key in client is missing, thus, this mode
6624 has no effect on client side (except that server requires that the
6625 client uses private channel key and normal channel traffic does not
6628 Also, invite mode works per se, but INVITE command does not work
6629 yet correctly, so you can set channel as invite only channel but
6630 inviting clients to the channel does not work (it is yet to be
6631 thought what's the best way to do it).
6633 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6634 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6635 Implemented CUMODE command to change user's mode on the channel.
6636 Supports all modes defined by the protocol specs.
6638 * Added NAMES command reply to return users modes on the channel.
6640 * Removed unnecessary and slow ciphers from lib/silccrypt.
6642 * Set SO_KEEPALIVE option to connection sockets by default.
6644 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6646 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6647 redefined the Notify Payload into protocol specs.
6649 * Added silc_id_payload_parse_id to get ID directly from raw
6652 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6655 accept searching by Client ID as well.
6657 * Added support for LEAVE and SIGNOFF notify types in client library.
6659 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6660 to parse ID Payload from raw data.
6662 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Added flags parameter into silc_ske_assemble_security_properties
6665 function in lib/silcske/silcske.[ch].
6667 * Changed notify client operation to fit better for notify messages
6668 sent by server. The notify payload received from server is now
6669 passed to the application (after parsing it to SilcNotifyPayload).
6670 It is application's responsibility to retrieve the arguments
6671 from the payload and show the message the way it wants. The message
6672 sent by server is implementation specific.
6674 * Changed public keys to comply with the protocol specification.
6675 Old public keys are not supported anymore and are not compatible.
6677 * Removed nickname from Channel Payload as the latest draft removed
6678 it. The client must resolve the nickname from the NAMES command
6679 reply received when it joined the channel.
6681 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6683 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Fixed some errors in protocol specification drafts.
6687 * Created lib/silccore/silcnotify.c to implement Notify Payload
6688 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6689 generic payloads described by protocol specifications. The file
6690 includes implementations for ID Payload and Argument Payload.
6692 * Changed Command Payload implementation to use the new Argument
6693 Payload. Changed command_xxxx_payload to command_payload_xxxx
6694 to comply with SILC coding conventions.
6696 * Added suppport for Argument Payload handling in Notify Payload
6697 implementation as protocol requires it. Added the new support
6698 into server and client lib as well.
6700 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Added support for multiple nicknames on same channel. [n] is
6703 added locally to the nickname if there are more than one same
6704 nicknames on the channel.
6706 * Server now sends all nicknames that matched WHOIS request.
6707 Client also shows the list received from server.
6709 * Added TOPIC command to client side. User can now set and show
6710 current topic on channel.
6712 * Added MOTD command to client and server. Also, server sends the
6713 motd when client connects to the server.
6715 * Changed version strings to comply ISO 8601.
6717 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6719 * Fixed protocol error handling in client library. It should now
6720 cope even if the SKE fails for some reason.
6722 * Made new protocol specification drafts for submitting to IETF.
6724 * Implemented TOPIC command to server in silcd/command.c.
6726 * Added two new notify types into lib/silccore/silcnotify.h:
6727 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6728 notify nickname change and topic setting/change on a channel.
6730 * API change of command_reply operation in client library. The
6731 application gets now the status type received from server as well.
6733 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6737 * Cras fixed and optimized the packet handling even further and
6738 it should work now. Minor change to the prototype of function
6739 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6741 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added new function into lib/silcutil/silcschedule.[ch]:
6744 silc_schedule_with_fd to select() a specified fd. The function
6745 returns after timeout expires or data arrives or goes. The
6746 function is used by packet routines to wait that all data is
6747 received from network.
6749 * Fixed data reading from network in lib/silccore/silcpacket.c.
6750 The code now assures that all data is read from the fd and then
6751 continues packet processing. This was a bug fix since the code
6752 used to drop some data in some circumstances.
6754 * Added new function into lib/silcclient/client.[ch]:
6755 silc_client_start_key_exchange to start key exchange after
6756 connection has been established to server. The code internally
6757 now uses this funtion but its main purpose was to provide it
6758 for applications that perform their own connecting. After
6759 application has created a connection it merely calls this
6760 function to start the key exchange between client and server.
6761 The library takes care of everything else after that.
6763 Updated also lib/silcclient/README to explain the usage of
6766 * Do not send to application information that connection has
6767 been established. Application gets notified it by connect
6770 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Applied cras's patch to add silc_schedule_one function. The
6773 function runs scheduler once and returns.
6775 * Fixed the scheduler after cras messed it up. The timeout
6776 handling works now as it's supposed to work.
6778 * Added into lib/silccore/ silcnotify.h to include notify
6779 message types support. Changed silc_server_send_notify*
6780 functions, in server.[ch], to support those new notify types.
6781 Added the support for the notify types into client library,
6782 as well. Added new notify client operation into ops.h in
6785 * Changed silc_server_packet_send_to_channel to send normal
6786 packets instead of just channel message packets. The function
6787 is now used to send the notify packets to channels. It is not
6788 used to send channel message packets anymore, as server never
6791 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6792 va_arg()s as it seems to require it nowadays. I guess, if SILC
6793 is compiled with older va_arg() the new code should work anyway.
6795 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Splitted core library. Core library (lib/silccore) includes
6798 now only SILC protocol specific core (and common) components.
6799 Created new utility library (lib/silcutil) that includes more
6800 generic purpose stuff. The stuff for util library was taken
6801 from the old core library. This was minor and easy split.
6803 * Created SILC Client Library (lib/silcclient) that includes
6804 implementation of the SILC client without user interface. This
6805 was major move from silc/ directory. The code has been changed
6806 so that it is transparent towards the user interface. The
6807 silc/ directory includes now the same user interface as before
6808 and it uses the new client library. Read lib/silcclient/README.
6809 Basicly, the client library performs everything else related
6810 to SILC except user interface handling. Also, configuration
6811 files are considered to be part of user interface and library
6812 does not handle them.
6814 This change also changed a lot of structures, function naming etc.
6815 Most important change was that SilcClientWindow object was
6816 renamed to SilcClientConnection in the client library. Created
6817 also new file lib/silcclient/ops.h. Also added new files
6818 silc/local_command.[ch] and silc/client_ops.[ch].
6820 All these changes were made to make it easier for user interface
6821 designers to create what ever user interface for the SILC client
6824 It is also expected that the server will be moved to lib
6825 directory as well and SILC Server Library will be created;
6826 sometimes in the future.
6828 * Removed Local commands from lib/silccore/silccommand.h as
6829 they are application specific and new client library does not
6830 handle any of those anymore.
6832 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6833 old client implementation in silc/.
6835 * Added support for callback functions in SILC_LOG_* macros.
6836 Application can now set its own callbacks that will be called
6837 instead of using the default functions that will always print
6838 the debug messages to stderr (or stdout). Also, debugging can
6839 now be disabled by setting silc_debug to FALSE and re-enabled by
6840 setting it to TRUE. Note, that logging will still work even
6841 if debugging is disabled.
6843 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6844 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6845 silc_log_reset_debug_callbacks.
6847 * To enable debugging in silc client one must give now -d
6848 option on command line.
6850 * Changed silc_schedule_init to automatically allocate task queues
6851 if they are not allocated before calling it.
6853 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * Added GMP 3.1 into math library.
6857 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6860 a channel in SILC network. The packet is used by servers and
6861 routers to notify other routers that user has left a channel.
6862 This little feature was missing until now. Added the feature
6863 to protocol specification as well.
6865 Added functions: silc_server_send_remove_channel_user and
6866 silc_server_remove_channel_user into server.[ch].
6868 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6869 lib/silccore/silcpacket.h. However, they are not implemented
6872 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Fixed joining to a channel and sending channel messages
6875 between server and router. The channel message sending should
6876 now work inside a cell.
6878 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Fixed the private message sending between server and router.
6881 The private message sending should now work inside a cell.
6883 * Added silc_server_replace_id into server.[ch] to replace
6884 existing ID in the SILC network.
6886 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6887 and silc_idlist_replace_server_id into idlist.[ch] in server.
6889 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Fixed the server to server connections. Server can again now
6892 connect to router. Router to router connections probably does
6895 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Added dynamic protocol registering support. Now protocols can
6898 registered and unregistered on the fly. Patch by cras.
6900 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Added lib/contrib directory to hold routines that some platforms
6903 don't have but are needed by SILC.
6905 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6906 into lin/contrib to provide getopt() and getopt_long() for
6907 those who don't have it.
6909 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Added AWAY command to client. When away message is set and
6912 client receives a private message packet the client automatically
6913 replies to the sender with the away message.
6915 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6916 bug seemed to be the cause of recent problems when compiling
6919 * Added version detection support to SKE protocol specification
6920 and added the new changes to the SKE implementation as well.
6921 There were other minor changes in the SKE protocol as well.
6923 Many changes in lib/silcske/silcske.[ch] and in
6924 lib/silcske/payload.[ch].
6926 * Added ^U functionality, clear input line. Patch from cras.
6928 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Mainly small bugfixes on core library. Fixed some debugging
6931 logging and buffer overflow in silclog.c.
6933 * Updated config.sub and config.guess on the distribution tree.
6935 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added command lagging support in server. Client may execute
6938 commands now only once in two seconds.
6940 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Optimized packet reception. MAC computation and checking is now
6943 also more optimized. A lot previously duplicated code is now
6944 used as generic by both client and server.
6946 * Fixed key pair generation in clientutil.c
6948 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added into lib/silccore/silcbufutil.[ch] new function;
6951 silc_buffer_realloc.
6953 * Moved generic packet sending/encryption functions to
6954 lib/silccore/silcpacket.[ch] from client and server. Some
6955 rewriting of the functions.
6957 * Moved all generic packet reception/decryption functions to
6958 lib/silccore/silcpacket.[ch] from client and server. The
6959 packet processing is now much cleaner in both client and server.
6960 These were major changes in both client and server.
6962 * Created many common functions in server to do packet sending.
6963 Previously code were duplicated a lot, this has been removed
6966 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Rewrote major parts of the ID cache system. Don't know
6969 whether it is better now or not but at least the API is more
6972 * Major rewrite on ID cache stuff on client because of the ID
6973 cache API changes. Added idlist.c to client.
6975 * Also major rewrite on ID cache stuff on server as well.
6976 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6977 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6978 in hand, instead they are all put into the ID cache system now.
6979 All server_idlist_* routines uses ID cache now instead of
6980 traversing its own lists (those lists does not exist anymore).
6981 SilcIDList though still exists. Also, SilcXXXEntry's are
6984 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Finally made the SKE implementation compliant to the protocol
6987 specification. All mp integers are now binary encoded as
6988 opposed being HEX encoded.
6990 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6993 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6994 functions: silc_[encode/decode]_pem. Also added function
6995 silc_encode_pem_file to PEM encode with newlines ('\n') for
6998 * SILC public keys are now encoded either PEM or binary. Same
6999 option is for private keys as well. By default private keys
7000 are binary encoded and public keys PEM encoded. Silly HEX
7001 encoding were removed.
7003 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7004 function to create fingerprints.
7006 * Fixed a bug in SHA1; does not change the original data anymore.
7008 * Partly implemented INFO command on client and server side.
7009 Fixed CLEAR command. Changes to SERVER command; show current
7010 server(s) when giving command without arguments. Added
7011 VERSION command to client.
7013 * Added check to server that unregistered connections cannot
7014 execute commands (unless it is specificly allowed).
7016 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Fixed screen refresh.
7020 * Fixed channel joining bug from client. On some circumstances
7021 client tried to join to a channel it had already joined.
7023 * Added public key verification process into client's protocol.c.
7024 The client now verifies the public key from user and saves
7025 it into ~./silc/serverkeys/ directory.
7027 Added into: clientutil.[ch]: silc_client_verify_server_key.
7029 * Changed SKE protocol's silc_ske_initiator_finish function
7030 to accept callback function that verifies the received public
7031 key. Removed old silc_ske_verify_public_key function.
7033 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7036 silc_pkcs_private_key[_data]_set.
7038 * Made the password and public authentication more cleaner in
7039 server's protocol.c.
7041 * Removed historic and obsolete protocol `channel_auth' from
7042 both client and server.
7044 * Removed wrong way of sending command status messages from
7045 server to client in server's command.c. The old way violated
7046 protocol specification.
7048 Changes to silccore/silccommand.[ch]: removed
7049 silc_command_encode_status_payload -> not needed anymore,
7050 changed silc_command_encode_payload_va to accept extra
7051 argument on variable argument list. The argument type must
7052 now be provided to the function. Also, added new function:
7053 silc_command_encode_reply_payload_va which is same as
7054 normal command_encode_payload_va except command status type
7055 is provided as extra argument.
7057 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * Added ~./silc directory handling. The directory includes the
7060 public and private keys for the client.
7062 Added silc_client_check_silc_dir, silc_client_create_identifier
7063 and silc_client_load_keys.
7065 * Implemented SILC protocol compliant public key. Added public
7066 and private key saving to and loading from files.
7068 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7069 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7070 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7071 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7072 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7074 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7075 silc_pkcs_load_[public/private]_key.
7077 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Added silc_server_get_route (route.[ch]) to get connection
7080 data for the fastest route for given ID.
7082 * Implemented INVITE command on client and server. The command
7083 were re-defined in the SILC Protocol Specification and the
7084 implementation now complies with the specification.
7086 * Implemented PING command on client and server.
7088 * Implemented NAMES command on client and server. The server side
7089 supports currently only normal server not router server yet.
7090 Some changes to NAMES definition in SILC protocol specification.
7092 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Implemented LEAVE command on client and server.
7096 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7097 again. This change was made to the protocol as well. Server
7098 should not violate the protocol specification anymore.
7100 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7103 was tested. SOCKS4 was not but should work anyway.
