1 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added `user_count' to the SilcChannelEntry which now tells the
4 number of users on the channel. The user count is now saved
5 in normal server of global channels as well. Affected files
6 silcd/server.c, idlist.h, packet_receive.c and command.c.
8 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
9 include file utility functions.
11 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
12 instead of calling directly OS routines.
14 * Fixed NICK change printing in Irssi SILC Client. Fixed
15 KICKED notify printing in Irssi SILC Client. Affected file
16 irssi/src/silc/core/client_ops.c.

24 * ROBOdoc documented the lib/silcske/silcske.h, and improved
25 the SKE interface a bit.
27 * Fixed padding problem in PKCS#1. The padding was not actually
28 random since the random number generator was used incorrectly.
29 This security bug affects only when encrypting with PKCS#1, and
30 it is not currently used at all in SILC. SILC only use signing
31 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
33 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

99 * Added new configuration options and blocks:
100 keepalive_secs, reconnect_count, reconnect_interval,
101 reconnect_interval_max, reconnect_keep_trying and
102 require_reverser_lookup. Added ConnectionParam block, and
103 implemented the connection parameters when connecting as
104 initiator and when accepting connections as responder.
106 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
107 whether given configuration value has been given already.
109 Affected files silcd/serverconfig.[c], server.[c].
111 * Splitted the doc/example_silcd.conf.in. Separated the crypto
112 algorithm parts and created new file silcalgs.conf, that
113 is now included from the example_silcd.conf.in.
115 * Optimized the silc_server_connect_to_router_second to take
116 the connection configuration object from the SilcServerConnection
117 object instead of finding it during the connecting phase.
118 Added the configuration object to SilcServerConnection struct.
119 Affected files silcd/server_internal.h, server.c.
121 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

133 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
135 * Unified the serverconfig.[ch]'s helper function interface.
136 Affected file silcd/serverconfig.[ch].
138 * Removed doc/example_silc.conf.in since it is redundant.
139 The make install will now install irssi/silc.conf file.
141 * Added new Passphrase and Publickey authentication methods to
142 config file, allowing both public key and passphrase based
143 authentication to be set at the same time.
145 Added `prefer_passphrase_auth' setting in config file which
146 can be used to set to prefer passwd auth if both passwd and
147 public key is set. If not set, public key is preferred.
148 This has effect only when being initiator (responder will try
151 Added support for authentication with passphrase and public key
152 at the same time. The passphrase is tried first always since
153 it is faster to check.
155 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
157 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

199 hash algorithm. Affected file lib/silccrypt/silcrng.c.
201 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Fixed the file transfer's key agreement payload to include
204 zero port also if the hostname is NULL because it could not
207 Call file transfer monitor callback now also if error occurs
208 during key agreement protocol.
210 Changed the silc_client_file_send interface to return the
211 SilcClientFileError instead of session id. The session ID
212 is returned into pointer provided as argument.
214 Check that the file exists locally before sending the
215 file transfer request at all.
217 Affected file lib/silcclient/client_ftp.c, silcapi.h.

229 file lib/silcutil/silclog.c.
231 * Fixed the channel message payload decryption in the function
232 silc_channel_message_payload_decrypt to not modify the original
233 buffer before it is verified that the message decrypted
234 correctly. Otherwise, next time it is called with correct
235 channel key it won't encrypt since the payload is corrupted.
236 Affected file lib/silccore/silcchannel.c.
238 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

251 the table with foreach callback. The current entry may
252 become invalid in the callback but it was referenced after
253 the callback returned.
255 Do not allow auto rehashing of hash table during the
256 silc_hash_table_foreach operation, for same reasons as it is
257 not allowed for SilcHashTableList. Affected files are
258 lib/silcutil/silchashtable.[ch].
260 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Defined DLLAPI into silcincludes.h and silcwin32.h for

266 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
268 * Fixed private message handling. It used some old code that
269 caused the client to crash. Affecte file is
270 lib/silcclient/client_prvmsg.c.
272 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
274 * Added function silc_client_add_channel,
275 silc_client_replace_channel_id, and removed functions
276 silc_client_new_channel_id and silc_idlist_get_channel_by_id
279 * Added cross reference of the joined channels to the
280 SilcClientEntry, and changed the SilcChannelEntry's
281 users list to SilcHashTable. The affected files are
282 lib/silcclient/idlist.[ch].
284 * Fixed a bug in hash table tarversing. While the hash table
285 is traversed with SilcHashTableList the table must not be
286 rehashed. It is now guaranteed that auto rehashable tables
287 are not rehashed while tarversing the list. Also defined that
288 silc_hash_table_rehash must not be called while tarversing
289 the table. Added function silc_hash_table_list_reset that must
290 be called after the tarversing is over. The affected files are
291 lib/silcutil/silchashtable.[ch].
293 * Changed all hash table traversing to call the new
294 silc_hash_table_list_reset in server and in client library.
296 * Added function silc_client_on_channel to return the
297 SilcChannelUser entry if the specified client entry is joined
298 on the specified channel. This is exported to application as
299 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
301 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
303 * Fixed founder regaining problem with JOIN command on normal
304 server. The notify for mode change must be sent always and
305 not only if !cmd->pending. Affected file silcd/command.c.
307 * Fixed the WHOWAS command's reply sending to support the
308 lists correctly. Affected file silcd/command.c.
310 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * When sending JOIN command to router for processing the
313 sender's old command identifier was not saved back to the
314 sender's command context, fixed now. The affected file is
317 * Create the key in JOIN command of the router did not return
318 the channel key, added check for this. Affected file is
321 * Fixed a channel ID update bug in JOIN command reply. Do
322 not directly upgrade the ID but call the function
323 silc_idlist_replace_channel_id if the ID was changed.
324 Affected file silcd/command_reply.c.
326 * Fixed memory leaks from command calling if it would fail.
327 Affected file silcd/command.c.

339 * Removed TRQ from lib/trq, not needed anymore.
341 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
342 with server connections. Later this will be configurable
343 in config file after new config file is done. Affected file
346 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
348 * Fixed a crash in server related to channel announcements.
349 Affected file silcd/server.c.
351 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
353 * Fixed memory leaks in silc_server_create_new_channel*
354 functions. Affected file silcd/server.c.
356 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
357 which ID was changed. This way the router will send the
358 user list for the channel again, and server won't be in
359 desync in some rare circumstances. Affected file is
360 silcd/packet_receive.c.
362 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
364 * Check for NULL socket pointer in the function

374 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
376 * Added lib/silcclient/client_ops_example.h as an template
377 file for application programmers to quickly start using
378 the SilcClientOperation functions in their application.
379 Updated the lib/silcclient/README as well to tell about this
380 nice file made available.
382 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Call silc_server_remove_from_channels when removing client
385 entry when NO_SUCH_CLIENT_ID was received. Affected file
386 is silcd/command_reply.c.
388 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
390 * Added server & router operator statistics updating. Affected
391 file silcd/packet_receive.c and silcd/command.c.
393 * Fixed the SERVER_SIGNOFF notify handling on normal server
394 not to save the history information for clients. Same was
395 fixed earlier in remove_clients_by_server function, but not
396 here. Affected file silcd/packet_receive.c.
398 * Raised the default connection-retry count from 4 to 7 in
399 server. Affected file silcd/server.h.
401 * Cancel any possible reconnect timeouts when we start the
402 key exchange. Affected file silcd/server.c.

405 given. Affected files silcd/server.[ch].
407 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
411 * Fixed the NICK command to always give the unformatted
412 nickname to the one giving the NICK command. If unformatted
413 nickname is cached already it will be formatted and the
414 local entry will always get the unformatted nickname.
415 Affected file lib/silcclient/idlist.c.
417 * Fixed some double frees from client library commands.
418 Affected file is lib/silcclient/command.c.
420 * Fixed CUMODE command in server to assure that no one can
421 change founder's mode than the founder itself, there was a
422 little bug. Affected file silcd/command.c.
424 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
426 * Removed the SilcClientCommandDestructor from the client
427 libary, it is not needed anymore. Affected files are
428 lib/silcclient/silcapi.h, command[_reply].[ch],
429 client_notify, idlist.c.
431 * Fixed GETKEY command to first resolve client, and then
432 resolve the server only if the client was not found, instead
433 of resolving both at the same time. Affected file is
434 lib/silcclient/command.c.
436 * Added silc_client_start_key_exchange_cb and lookup the
437 remote hostname and IP address before starting the key
438 exchange with server. The affected file is
439 lib/silcclient/client.c.
441 * The server's public key is now saved using the IP address
442 of the server and not the servername for the filename.
443 The hostname public key filename is checked as an fall back
444 method if the IP address based filename is not found.
446 Fixed the GETKEY command to save the fetched server key
449 Print the remote server's hostname now when new key is
450 received during connection process. Affected file is
451 irssi/src/silc/core/client_ops.c.
453 * Return always our own public key to the client if it asks
454 for it with GETKEY command. Affected file silcd/command.c.
456 * Removed the use_auto_addr variable from default config
457 file since it was in wrong section. Affected file is
460 * Fixed TOPIC_CHANGE notification to not route it when it
461 was sent using silc_server_send_notify_to_channel function.
462 Affected file silcd/command.c.
464 * Fixed silc_server_send_notify_kicked to send the kicker's
465 Client ID also, it was missing. Affected files are
466 silcd/command.c, silcd/packet_send.[ch].
468 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
470 * Do not save client history information in SERVER_SIGNOFF.
471 Fixes the bug in normal server that it does not detect
472 the client becoming valid after the server becomes back
473 online. Affected file silcd/server_util.c.
475 * Added `sock_error' field into the SilcSocketConnection
476 context. When error occurs during socket operation (read
477 or write) the error is saved. Added also new function
478 silc_socket_get_error to return human readable socket error
479 message. Affected files are lib/silcutil/silcsockconn.[ch],
480 lib/silcutil/unix/silcunixsockconn.c, and
481 lib/silcutil/win32/silcwin32sockconn.c.
483 * The server now prints the socket error message in the
484 signoff for client. Affected file silcd/server.c.
486 * Fixed the `created' channel information sending from router
487 to server in JOIN command. Checks now whether the channel
488 really was created or not and set it according that.
490 Fixed the JOIN command to use the client entry's current
491 ID during the joining procedure instead of the one it sent
492 in the command (it is checked though), since it can change
493 between the packet processing and command processing, and
494 would just case unnecessary pain in the client end. Affected
495 file silcd/command.c.
497 * Fixed a channel key payload sending to use correct channel
498 ID when the server was forced to change the channel's ID by
499 router. Router sent the key payload with the old Channel ID.
500 Affected file silcd/packet_receive.c.
502 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
504 * Call silc_server_save_channel_key only if the key payload
505 was provided in the JOIN command's command reply. Affected
506 file silcd/command_reply.c.
508 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Fixed silc_mp_sizeinbase to return the value correctly with
511 MPI. Affected file lib/silcmath/mp_mpi.c.
513 * Fixed the stop_server signal to correctly stop the scheduler
514 and gracefully stop the server when SIGTERM or SIGINT signals
515 are received. Affected file silcd/silcd.c.
517 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
519 * Simple handling of TERM and HUP signals. Also added some log
520 flushing call around. Affected file is
523 * Fixed small bugs in silclog.c. Now buffering output will take
524 effect after 10 seconds since startup: This will ensure that
525 no important startup messages are lost. Also output redirection
526 will preserve original format ([Date] [Type] message).
527 Affected file is lib/silcutil/silclog.c.
529 * Added two options to the config file, in the logging section:
530 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
531 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
533 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
535 * Do not print the warning about log files not being initialized
536 more than once to avoid excess logging. Affected file is
537 lib/silcutil/silclog.c.
539 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
540 the SIM copying in make install in Makefile.am.pre.
542 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
544 * Rewritten silclog APIs. Globally interesting changes follows:
545 silc_log_set_files() changed to silc_log_set_file().
546 silc_log_set_callbacks() changed to silc_log_set_callback().
547 ROBOdoc documented silclog header file.
548 SilcLogCb now returns bool to wether inihibit the default
549 handler or not (to keep the old behaviour return always TRUE).
550 The new APIs should also fix the problem of the
551 silcd_error.log file that was written in the current directory.
554 Log files streams will remain opened after silc_log_set_file()
555 call, means less CPU usage notably on high traffic servers.
556 File streams are now full buffered, and flushed to the disk
557 every 5 minutes, lesses HD activity and CPU usage.
558 Messages can be redirected, allowing admins to configure
559 one single logfile for all server messages.
560 the silc_log_quick global variable to activate fast-logging.
561 Affected files lib/silcutil/silclog.[ch]
563 * Changed some code to conform new silclog APIs. Affected
564 files are doc/example_silcd.conf.in, silcd/server.c
565 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
568 * Fixed a memory leak that could occur in some situations.
569 Affected file silcd/serverconfig.c.
571 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
573 * Added the silc_client_del_client to remove the client from
574 all channels as well. Affected file lib/silcclient/idlist.c.
576 * Fixed the client library to correctly remove the client
577 from all channels when the client entry is being destroyed.
578 Affected file lib/silcclient/client_notify.c, command.c.
580 * Added auto-nicking support to the client library. If the
581 applicatio now sets client->nickname it will be sent to the
582 server after connecting by the library. This way for example
583 SILCNICK (or IRCNICK) environment variables will have effect
584 and always change the nickname automatically to whatever
585 it is wanted. Affected file lib/silcclient/client.[ch].
587 * Renamed silc_server_command_bad_chars to the
588 silc_server_name_bad_chars and moved it to the
589 silcd/server_util.[ch]. Added also new function
590 silc_server_name_modify_bad to return nickname that
591 includes bad characters as new nickname without those
592 bad characters. This check and modify is now used in
593 silc_server_new_client when the username is initially set
594 as nickname, so it must be checked to be valid nickname.
595 Affected file silcd/packet_receive.c.
597 * The nickname length is now taken from the packet for real
598 and not trusted to strlen() since it clearly can return
599 wrong length for nickname including bad characters. This
600 also applies to channel names. Affected file silcd/command.c.
602 * Removed the lib/silcsilm/modules directory. Modules are now
603 compiled into the lib/silcsim. Fixed the copying of the
604 modules to follow symbolic links in Makefile.am.pre.
606 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Fixed silc_string_regexify list creation. Fixes bugs with
609 BAN and INVITE commands in server. The affected file is
610 lib/silcutil/unix/silcunixutil.c.
612 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
614 * Removed the command destructor entirely from the server's
615 command and command reply routines. It is not needed, and
616 its usage was buggy and caused crashes. Affected files are
617 silcd/command[_reply].[ch].
619 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
621 * Cancel protocol and NULL sock->protocol if timeout
622 occurred during protocol. Affected file silcd/server.c.
624 * Cancel protocol timeouts always before calling the final
625 callback, to assure that after final callback is called
626 no other state will be called for the protocol anymore.
627 Affected file silcd/protocol.c.
629 * Print error log if incoming connection configuration could
630 not be found. Affected file silcd/server.c.
632 * Fixed JOIN command to correctly save the founder mode
633 to the client on normal SILC server, when the channel
634 was created by the router. Affected file silcd/command.c.
636 * Fixed LIST command (hopefully) to send correct reply
637 packets. Affected file silcd/command.c.
639 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
641 * The silc_packet_receive_process now returns FALSE if the
642 read data was invalid packet, and TRUE if it was ok.
644 The server now checks that if unauthenticated connection
645 sends data and its processing fails the server will close
646 the connection since it could be a malicious flooder.
648 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
650 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
652 * Make sure the warning about error opening a log file is
653 printed only once and not everytime it fails (produces
654 too much useless log). Affected file lib/silcutil/silclog.c.
656 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
658 * Made the silc_server_daemonise() function more readable.
659 Affected file silcd/server.c.
661 * Pid file is now optional, the user may comment it out from
662 the config file. Removed define SILC_SERVER_PID_FILE, we
663 don't need a default any longer. Affected file
664 configure.in.pre, lib/Makefile.am.pre.
666 * Make some use of the pid file. The server now dies at startup
667 if it detects a valid pid file on his path. The server would
668 die anyway in this circumstance, because of the bind() failure.
669 Affected file silcd/silcd.c.
671 * No longer compiling lib/dotconf.
673 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
675 * Fixed JOIN command parsing not to crash. Affected file
676 lib/silcclient/command.c.
678 * Fied the NICK_CHANGE notify to add the new client entry
679 even it is resolved. This removes an <[unknown]> nick
680 thingy bug in the client. Affected file is
681 lib/silcclient/client_notify.c.
683 * Do not try to allocate 0 bytes (efence does not like it)
684 in lib/silccore/silccomand.c when encoding payload.
686 * Do not take IRCNICK as nickname in Irssi SILC client since
687 it is not possible to set nickname before hand connecting
688 the server (TODO has an entry about adding auto-nicking
691 * Changed the silc_server_command_pending to check whether
692 there already exists an pending entry with the specified
693 command, command identifier and pending callback. This is
694 to fix IDENTIFY and WHOIS related crashes that may register
695 multiple pending commands with same identifier. Affected
696 file silcd/command.c.
698 * Fixed the server to reconnect to the router even if it
699 was already reconnecting and EOF was received. This to
700 fix a possibility that the server wouldn't ever try to
701 auto-reconnect to the router. Affected file silcd/server.c.
703 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Fixed the server's password authentication to use the
706 length of the locally saved password, and not the one
707 sent in the packet. Affected file silcd/protocol.c.
709 * Fixed same password authentication problem in the
710 Authentication Payload handling routines in
711 lib/silccore/silcauth.c.
713 * Yet another password authentication problem fixed with
714 channel password handling in silcd/command.c.
716 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
718 * If first character of string in silc_parse_userfqdn is '@'
719 then do not parse it. Affected file is
720 lib/silcutil/silcutil.c.
722 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Fixed minor bug in IDENTIFY command reply sending, which
725 caused various weird problems during JOIN when it was
726 resolving names for users. Affected file silcd/command.c.
728 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
730 * Fixed the IDENTIFY command reply sending to chech better valid
731 clients. It was possible to send incomplete list of replies.
732 Affected file silcd/command.c.
734 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
736 * Added silc_client_command[s]_[un]register functions now to
737 dynamically register the commands in client library. Removed
738 the static table of commands. This allows the client library
739 to call commands without causing the application to know about
740 what commands library has called.
742 Removed the INFO command reply kludge to detect when the command
743 was called by library. Now library use its own command reply
744 function for INFO command.
746 Added function silc_client_command_call to call a command.
747 Application can use it to call command, not access the structure
750 Now all commands that are sent by the client library (not
751 explicitly sent by application) use own command reply functions.
753 Affected files around lib/silcclient/ and in
754 irssi/src/silc/core/.
756 * Fixed the WHOIS command reply sending to chech better valid
757 clients. It was possible to send incomplete list of replies.
759 Fixed the WHOIS and IDENTIFY to send the request to router
760 if normal server did not do it and did not find any results.
762 Affected file silcd/command.c.
764 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
766 * Moved the internal data from SilcClient context into its
767 own file, not accesible to application. Affected files
768 lib/silcclient/client.h and lib/silcclient/client_internal.h,
769 and other files in client library.
771 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
773 * Added doc/examples installation target in Makefile.am.pre.
776 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
778 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
779 commands the found client entry will be removed from the
780 cache, after notifying application about the error. Affected
781 file lib/silcclient/command_reply.c.
783 * Changed the /MSG to check for exact nickname user gave, and
784 not let `nick' match `nick@host' if it is only one found. Now,
785 user must type the exact nickname (like nick@host2) even if
786 there are no more than one same nicks found. This is to avoid
787 a possibility of sending nickname to wrong nickname since
788 `nick' could match `nick@host'. Affected file is
789 irssi/src/core/silc-servers.c.
791 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
793 * Do not print "you are now server operator" or similar when
794 giving /away command. Affected files are
795 irssi/src/silc/core/client_ops.c, silc-servers.h.
797 * Made the silc_server_command_pending_error_check to send
798 the same command reply payload it received back to the
799 original sender of the command. This way all arguments
800 that was received by the server will be received by the
801 client too. Affected file silcd/command.c.
803 * Added the silc_idcache_add to return the created cache entry
804 to a pointer. Affected file lib/silccore/silcidcache.[ch].
806 * Add global clients to expire if they are not on any channel.
807 This is because normal server will never know if they signoff
808 if they are not on any channel. The cache expiry will take
809 case of these entries. This is done by normal servers only.
810 The affected files are silcd/command_reply.c,
811 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
813 * If server receives invalid ID notification for WHOIS or
814 IDENTIFY and the ID exists in the lists, it is removed.
815 Affected file silcd/command_reply.c.
817 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
818 in client then client entry that it matches is searched and
819 the nickname is printed on the screen for user. Affected
820 file irssi/src/silc/core/client_ops.c.
822 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Use cache entry expire time in the LIST command reply to
825 purge old entries from the cache after the LIST command
826 reply has been received. This way we don't have non-existent
827 entries in the cache for too long. Affected file is
828 silcd/command_reply.c.
830 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * If we are normal server, and we've not resolved client info
833 in WHOIS or IDENTIFY from router, and it is global client,
834 we'll check whether it is on some channel. If it is not
835 then we cannot be sure about its validity and will resolve it
836 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
837 file silcd/command.c.
839 * Search channel by name (if possible) rather than by ID
840 in IDENTIFY command's command reply. Affected file is
841 silcd/command_reply.c.
843 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Distribute to the channel passphrase in CMODE_CHANGE notify.
846 Updated specs and implemented it. Affected file silcd/command.c,
847 silcd/packet_send.c and silcd/packet_receive.c.
849 * Implemented the <founder auth> payload handling in the JOIN
850 command. If provided all conditions for channel joining
851 except requirement to provide correct passphrase can be
852 overrided by the channel founder. Updated the protocol specs.
853 Affected file silcd/command.c.
855 Added support for founder auth in JOIN command in client
856 library. Fixed the parsing of the JOIN command now to support
857 all options as they should be. The affected file is
858 lib/silcclient/command.c.
860 * Optimized the WHOIS and IDENTIFY commands to send the request
861 to router only if it includes nicknames or other names. If
862 they include only IDs then check the local cache first before
863 routing. Affected file is silcd/command.c.
865 * Added channels topic announcements. Affected file is
866 silcd/packet_receive.c and silcd/server.c.
868 * Fixed the silc_server_send_notify_topic_set to really destine
869 the packet to channel. Affected file silcd/packet_send.c.
871 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
872 library. Affected file lib/silcclient/client_notify.c.
874 * Added UMODE announcements. Affected file silcd/server.c.
876 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Memory leak fixes in:
880 lib/silcutil/silcsockconn.c
881 lib/silcske/silcske.c
884 lib/silccrypt/silcpkcs.c
885 lib/silccore/silccommand.c
886 lib/silccore/silcidcache.c
891 * ROBOdoc documented the lib/silcske/groups.h file and a
892 bit changed the interface for better.
894 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
896 * Update the client entry context in the ID cache after
897 nick change. Affected file lib/silcclient/command.c.
898 Fixes the CUMODE command when regaining founder privileges,
899 and a little WHOIS problem.
901 * Fixed silc_net_gethostbyname to correctly call the
902 inet_ntop. Affected file lib/silcutil/silcnet.c.
904 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
906 * Added IPv6 support checking to the configure.in.pre, added
907 also --enable-ipv6 option to override the check. Affected
908 file configure.in.pre.
910 * The silc_thread_create now calls the start function
911 directly if threads support is not compiled in. Removes
912 ugly #ifdef's from generic code. Affected files are
913 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
915 * Added silc_net_gethostby[name/addr]_async to asynchronously
916 resolve. Affected files are lib/silcutil/silcnet.[ch].
918 * Added support for rendering IPv6 based server, client and
919 channel IDs. Affected file lib/silcutil/silcutil.c.
921 * Added support for creating IPv6 based server IDs. Affected
922 file is silcd/serverid.c.
924 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
926 * Added silc_net_gethostby[addr/name] into the
927 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
928 routines. Added silc_net_is_ip[4/6]. Affected file is
929 lib/silcutil/unix/silcunixnet.c. All routines that take
930 address as argument now supports both IPv4 and IPv6 addresses.
932 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
934 * Fixed LIST command reply sending in server. Affected file
937 * Server now sends the kicker's client ID in the KICK notify
938 to the kicked client. Affected file silcd/command.c.
940 * The client library now parses the kickers client ID and
941 UI displays it. Affected files lib/silcclient/client_notify.c
942 and irssi/src/silc/core/silc-channels.c, module-formats.c.
944 * Made all payload parsing function prototypes consistent.
945 They all take now const unsigned char * and uint32 pair as
946 the payload data instead of SilcBuffer. Changes all around
947 the source tree. Other unsigned char* -> const unsigned char*
948 changes around the tree as well.
950 * Optimized SFTP client and server packet sending not to
951 allocate new buffer for each packet but to recycle the
952 first allocated buffer. Affected files are
953 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
955 * Optimized the SFTP client to use SilcList instead of
956 SilcDList for requests, because it is faster. Affected file
957 is lib/silcsftp/sftp_client.c.
959 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
960 into lib/silccore/silcid.[ch].
962 Renamed silcpayload.[ch] into silcargument.[ch].
964 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
966 * If client entry is deleted with active key agreement
967 session, abort the session.
969 The silc_client_abort_key_agreement now calls the completion
970 callback with new SILC_KEY_AGREEMENT_ABORTED status.
972 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
975 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * Don't use __restrict in older GCC's. Affected file is
978 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
980 * silc_net_localhost now attempts to reverse lookup the
981 IP/hostname. Affected file lib/silcutil/silcnet.c.
983 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
984 command. It can be used to gain founder privileges at
985 the same time when joining the channel.
987 Defined that the SILC_NOTIFY_TYPE_KICKED send the
988 kicker's client ID as well. Updated protocol specs.
990 Defined that the server must send SILC_COMMAND_IDENTIFY
991 command reply with error status to client who sent
992 private message with invalid client ID.
994 Updated the protocol specification.
996 * Added silc_server_send_command_reply to send any
997 command reply. Affected file silcd/packet_send.[ch].
999 * Added silc_id_payload_encode_data to encode ID payload
1000 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1002 * The server now send IDENTIFY command reply with error
1003 status if client ID in private message is invalid. Affected
1004 file silcd/packet_receive.c.
1006 * Save the server key file with server's IP address in
1007 the filename instead of hostname. The affected file is
1008 irssi/src/silc/core/client_ops.c.
1010 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1015 * Added libtool support for compiling shared objects in
1016 lib/silcsim. Affected file configure.in.pre and
1017 lib/silcsim/Makefile.am. Original patch by cras.
1019 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Pid file configuration, and server's config file fixes
1022 patch by toma. Updated CREDITS file.
1024 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Fixed silc_client_channel_message to not try to decrypt
1027 the message twice if it resolved the destination client
1028 information. This could cause of dropping one channel
1029 message. Affected file lib/silcclient/client_channel.c.
1031 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1034 lib/silcclient/client.c. This function is used when the SILC
1035 Client is run under some other scheduler, or event loop or
1036 main loop. On GUI applications, for example this may be
1037 desired to used to run the client under the GUI application's
1038 main loop. Typically the GUI application would register an
1039 idle task that calls this function multiple times in a second
1040 to quickly process the SILC specific data.
1042 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1044 * Fixed silc_server_drop() for dropping the supplementary
1045 groups as well, this could cause a security hole on some
1048 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1053 * Write PID file after dropping privileges. Added -F option
1054 to run server on foreground. A patch by debolaz.
1055 Affected files silcd/server.c, silcd/silcd.c.
1057 * Fixed MOTD to return the MOTD file server name. Affected
1058 file silcd/command.c.
1060 * Added INFO command reply handling to the Irssi SILC Client.
1061 Affected file irssi/src/silc/core/client_ops.c.
1063 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Fixed the silc_idcache_list_* routines to really support
1066 the dynamic list. Fixes a crash. Affected file is
1067 lib/silccore/silcidcache.c.
1069 * Fixed the LIST command reply to really call LIST command's
1070 pending callbacks. Affected file silcd/command_reply.c.
1072 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Update conn->local_entry->nickname after giving NICK
1075 command. Affected file lib/silcclient/command.c.
1077 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1079 * Added the [pid] option to the silcd configuration file
1081 Affected files: serverconfig.[ch] and silcd.c
1083 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Save fingerprint in WHOIS command reply in server.
1086 Affected file silcd/command_reply.c.
1088 * Fixed NICK commands pending callback registration.
1089 Affected file lib/silcclient/command.c.
1091 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Use ++server->cmd_ident when sending commands in server,
1094 instead of random number. Affected file silcd/command.c.
1096 * Fixed GETKEY command reply to call actually GETKEY pending
1097 command callbacks. Affected file silcd/command_reply.c.
1099 * A bit stricter check for nicknames. Check for same nickname
1100 in NICK command also. Affected file silcd/command.c.
1102 * Do not call INFO command everytime client ID changes, only
1103 during first connecting. Affected file lib/silcclient/client.c.
1105 * Set the new nickname only after successful command reply for
1106 NICK command is returned by server. Affected file
1107 lib/silcclient/command.c.
1109 * Remove nicknames from nicklist during server_signoff notify.
1110 Should fix /NAMES bit more. The affected file is
1111 irssi/src/silc/core/silc-channels.c.
1113 * Added `fingerprint' field to the SilcIDListData in the
1114 silcd/idlist.h to hold the fingerprint of the client's
1117 Send the fingerprint of the client's public key in WHOIS
1120 Affected files silcd/command.c, and silcd/idlist.[ch].
1122 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1123 create fingerprint from given data.
1125 * Show the fingerprint of the client's public key in WHOIS.
1126 Affected files irssi/src/module-formats.[ch] and
1127 irssi/src/silc/core/client_ops.c.
1129 * Format the multiple same nicknames also during JOIN and
1130 NICK_CHANGE notifys. Affected file is
1131 lib/silcclient/client_notify.c.
1133 * Do not print error on screen for invalid private message
1134 payload since it can come if someone is sending private
1135 messages with wrong key. Affected file
1136 lib/silccore/silcprivate.c.
1138 * Fixed multiple concurrent /PING crash. Affected file
1139 lib/silcclient/command.c.
1141 * Changed the wrong ID encoding. All IP addresses must be
1142 in MSB first order in encoded format. They were encoded
1143 wrong and was in LSB format. Affected files are
1144 silcd/serverid.c, lib/silcutil/silcutil.c.
1146 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1148 * Call the `connect' client operation through the scheduler
1149 in case of error. Affected file lib/silcclient/client.c.
1151 * Call the `failure' client operation even if the error
1152 occurred locally during a protocol. Affected file is
1153 lib/silcclient/protocol.c.
1155 * Added support of sending LIST command to router from normal
1156 server. This way normal server can get list of all channels
1157 in the network too. Fixed the channel list sending in the
1158 server too. Affected files are silcd/command.c, and
1159 silcd/command_reply.[ch].
1161 * Added silc_server_update_channels_by_server and
1162 silc_server_remove_channels_by_server. They are used during
1163 disconnection of primary router and in backup router protocol.
1164 Affected file silcd/server_util.[ch], silcd/server.c and
1165 silcd/server_backup.c.
1167 * Fixed channel adding to global list in IDENTIFY command
1168 reply in server. Affected file silcd/command_reply.c.
1170 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * If the incoming packet type is REKEY or REKEY_DONE process
1173 that packet always synchronously. Fixes yet another MAC
1174 failed error on slow (dialup) connections. Affected file
1175 lib/silcclient/client.c and silcd/server.c.
1177 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Call check_version SKE callback for initiator too. Affected
1180 file lib/silcske/silcske.c.
1182 * Implemented fix for security hole found in the SKE that was
1183 fixed in the specification few days back; the initiator's
1184 public key is now added to the HASH value computation.
1185 Added backwards support for the old way of doing it too, for
1186 old clients and old servers. Affected file is
1187 lib/silcske/silcske.c.
1189 * Enabled mutual authentication by default in SKE. If initiator
1190 is not providing mutual authentication the responder will
1191 force it. This will provide the proof of posession of the
1192 private key for responder. The affected files are
1193 lib/silcclient/protocol.c and silcd/protocol.c.
1195 * Do not cache anymore the server's public key during SKE.
1196 We do mutual authentication so the proof of posession of
1197 private key is done, and if the server is authenticated in
1198 conn auth protocol with public key we must have the public
1199 key already. Affected file silcd/protocol.c.
1201 * Added new global debug variable: silc_debug_hexdump. If
1202 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1203 file lib/silcutil/silclog.[ch].
1205 * Fixed compilation warning due to char * -> const char *.
1206 Affected files lib/silcutil/silcnet.h, and
1207 lib/silccore/silcauth.[ch].
1209 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Fixed CMODE command when new channel key was created. If
1212 the creation failed the old key was removed. Next time giving
1213 same command would crash the server since the old key was
1214 freed already. Affected file silcd/command.c.
1216 * Fixed the silc_server_announce_get_channels to not crash
1217 on reconnect. Affected file silcd/server.c.
1219 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Added silc_log_set_debug_string function to set a regex
1222 string to match for debug output. Only the function names,
1223 or filenames matching the given debug string is actually
1224 printed. This way it is possible to filter out those debug
1225 strings that user is not interested in.
1227 Fixed a bug in silc_string_regexify.
1229 Affected files lib/silcutil/silclog.[ch], and
1230 lib/silcutil/unix/silcunixutil.c.
1232 * Changed the -d options in both server and Irssi SILC client
1233 to take the debug string as argument. Affected files
1234 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1236 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Added silc_hash_babbleprint to create a Bubble Babble
1239 Encoded fingerprint. The encoding is developed by Antti
1240 Huima (draft-huima-babble-01.txt), and it creates human
1241 readable strings out of binary data. Affected file
1242 lib/silccrypt/silchash.[ch].
1244 * Print the babble print now in addition of fingerprint as well
1245 in Irssi SILC client. Affected files are
1246 irssi/src/fe-common/silc/module-formats.[ch],
1247 irssi/src/fe-common/silc/core/client_ops.c.
1249 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1251 * Fixed a security problem found in SKE. The initiator's
1252 public key too is now added to the HASH hash value creation
1253 which is signed by the responder to create the SIGN value.
1254 This will prevent anyone in the middle to lie to the responder
1255 about the initiator's public key. If this is done now, the
1256 man in the middle will get caught. Updated the protocol
1259 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1261 * Better installation directory handling. Configure module
1262 paths and other paths automatically to example_silc* files
1263 in doc/. A patch by toma.
1265 * Fixed compiler warning from MPI library, and from SILC RNG.
1268 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1269 It can be configured with ./configure. A patch by toma.
1271 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Find correct make to use in prepare-clean. A patch by
1274 toma. Affected file prepare-clean.
1276 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1278 * Added irssi variables use_auto_addr, auto_bind_ip,
1279 auto_bind_port and auto_public_ip.
1281 * Changed the interface for silc_client_send_key_agreement
1282 in lib/silcclient/silcapi.h
1286 irssi/src/silc/core/silc-core.c
1288 lib/silcclient/silcapi.h
1289 irssi/src/silc/core/silc-channels.c
1290 lib/silcclient/client_keyagr.c
1293 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Added silc_pkcs_public_key_compare to compare two
1296 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1298 * Check that the client who set the founder mode on the
1299 channel is the same client that is giving the founder
1300 mode to itself. It is done by comparing the saved public
1301 key (it is saved even in the authentication is passphrase).
1302 Affected file silcd/command.c.
1304 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Do not process packet for disconnected socket connection.
1307 Affected file lib/silccore/silcpacket.c.
1309 * Process the DISCONNECT packet through scheduler in the
1310 client library. Affected file lib/silcclient/client.c.
1312 * Fixed the silc_client_packet_parse to not to increase
1313 the packet sequence number if the conn->sock and the
1314 current socket connection is not same. This can happen
1315 for example during key agreement when the conn includes
1316 multiple socket connections (listeners). Affected file
1317 lib/silcclient/client.c.
1319 * The sender of the file transfer request now provides also
1320 the pointer (listener) for the key exchange protocol. If
1321 the listener cannot be created then it sends empty key
1322 agreement and lets the receiver provide the listener.
1324 Added `local_ip' and `local_port' arguments to the
1325 silc_client_file_send. If they are provided they are used,
1326 if not then it will attempt to find local IP address, if
1327 not found or bind fails then the remote client will provide
1330 Affected files are lib/silcclient/client_ftp.c and
1331 lib/silcclient/silcapi.h.
1333 * Extended the FILE SEND command to support defining the
1334 local IP and port for key exchange listener. They are
1335 optional. Affected file irssi/src/silc/core/silc-servers.c.
1337 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Defined to WHOIS command reply the sending of fingerprint
1340 of the client's public key (if the proof of posession of the
1341 corresponding private key is verified by the server).
1342 Updated to the protocol specification.
1344 * Added support of receiving the client's public key's
1345 fingerprint in command reply in client library. Affected
1346 file is lib/silcclient/command_reply.c, and
1347 lib/silcclient/idlist.[ch].
1349 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Do not send over 128 chars long nickname to the server
1352 in NICK command. Affected file lib/silcclient/command.c.
1354 * Do not send over 256 chars long channel names to the server
1355 in JOIN command. Affected file lib/silcclient/command.c.
1357 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1359 * Assure that silc_server_close_connection cannot be called
1360 twice for same socket context. Affected file is
1363 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Send error message to application if opening file for
1366 writing during file transfer fails. Affected file is
1367 lib/silcclient/client_ftp.c.
1369 Remove all file transfer sessions for a client that we're
1370 removing from ID cache.
1372 Affected file is lib/silcclient/client_ftp.c.
1374 * Fixed silc_net_addr2bin to return correct address. Affected
1375 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1377 * Fixed file transfer session removing on signoff notify.
1378 Affected file irssi/src/silc/core/silc-servers.c.
1380 * Added the SilcClientFileError to be returned in the monitor
1381 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1382 Affected file lib/silcclient/silcapi.h.
1384 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Fixed a crash in silc_client_ftp_free_sessions and
1387 silc_client_ftp_session_free_client. Affected file
1388 lib/silcclient/client_ftp.c.
1390 * Added `disabled' field in the SilcChannelEntry in the server
1391 to indicate if the server entry is disabled. Affected file
1392 silcd/idlist.h, silcd/command[_reply].c.
1394 * SILC server adds now /var/run/silcd.pid everytime it is
1395 started. Affected file silcd/silcd.c.
1397 * Added silc_server_packet_send_clients to send a packet to
1398 the provided table of client entries. Affected file
1399 silcd/packet_send.[ch].
1401 * Fixed a crash in client resolving in client_prvmsg.c in
1402 client library. Affected file lib/silcclient/client_prvmsg.c.
1404 * Do not actually remove the client directly from ID cache
1405 during SERVER_SIGNOFF, but invalidate it. This way we
1406 preserve the WHOWAS info for the client. Affected file
1407 silcd/server_util.c.
1409 * Fixed SERVER_SIGNOFF notify handling in the server. The
1410 server is now able to process incoming SERVER_SIGNOFF notify
1411 for a server that it doesn't even know about. It will remove
1412 the clients provided in the notify. Affected file
1413 silcd/packet_receive.c.
1415 * Check for partial packet in data queue after every packet that
1416 was found from the queue. Return and wait for more data if
1417 there is partial data in queue. Affected file is
1418 lib/silccore/silcpacket.c.
1420 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Added SilcClietFileError enum to indicate error in
1423 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1424 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1425 Affected files lib/silcclient/silcapi.h and
1426 lib/silcclient/client_ftp.c.
1428 * Check that newsize in silc_buffer_realloc is larger than
1429 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1431 * Added better monitor of file transfers. It now monitors
1432 key agreement protocol during the file transfer too. Added
1433 error reporting too. Affected files
1434 irssi/src/silc/core/silc-servers.c,
1435 irssi/src/fe-common/silc/module-formats.[ch].
1437 * Wrote a help file for FILE command.
1439 * Added silc_rng_global_get_byte_fast to get not-so-secure
1440 random data as fast as possible. Random data is read from
1441 /dev/urandom if available and from the SILC RNG if not
1442 available. It is used in padding generation. Affected file
1443 lib/silccrypt/silcrng.[ch].
1445 * All packets in client library are now processed synchronously.
1446 Optimized packet processing a lot. Affected file
1447 lib/silcclient/client.c.
1449 * All server connection packets are processing synchronously
1450 now in server, to optimize packet processing. Affected file
1453 * Include files are installed now only in Toolkit distribution
1454 if make install is given. Affected files: all Makefile.am's.
1456 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Assure that silc_client_notify_by_server_resolve does not
1459 resolve the client information multiple times. If it cannot
1460 be found by the first it cannot be found at all. Affected
1461 file lib/silcclient/client_notify.c.
1463 * Fixed WHOWAS command reply calling. Affected file
1464 lib/silcclient/command_reply.c.
1466 * Removed all references to silc_idlist_get_client from the
1467 Irssi SILC client since that call is internal call used by
1468 the library. The Irssi SILC client will use now client
1469 retrieval functions found in silcapi.h.
1471 * Fixed a bug in resolving nickname info before sending
1472 private message. It used freed memory. Affected file
1473 irssi/src/silc/core/silc-servers.c.
1475 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Assure my_channels statistics cannot go negative in server.
1478 Affected files silcd/server.c, silcd/server_util.c.
1480 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1484 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Win32 Toolkit changes. Affected files
1487 win32/silc.dsw, win32/libsilc/libsilc.def,
1488 win32/libsilcclient/libsilc.def,
1489 lib/silcutil/silcutil.c, and
1490 lib/sftp/sftp_fs_memory.c.
1492 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Added silc_net_localip to return local host's IP address.
1495 Affected file lib/silcutil/silcnet.[ch].
1497 * If key exchange or rekey protocol is active for a connection
1498 parse all packets syncronously since there might be packets
1499 in packet queue that we are not able to process without first
1500 processing packets before them. Affected file silcd/server,
1501 lib/silcclient/client.c.
1503 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1504 whether library should continue processing the packet.
1505 Affected file lib/silccore/silcpacket.h.
1507 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1508 SilcSFTPMonitorData to SFTP server to monitor various
1509 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1510 lib/silcsftp/sftp_server.c.
1512 * Added silc_file_size to return file size. Affected file
1513 lib/silcutil/silcutil.[ch].
1515 * Implemented the file transfer support for the client library.
1516 Added preliminary support for simple client to client one-file
1517 transmission. Affected file lib/silcclient/client_ftp.c,
1518 lib/silccilent/client.[ch].
1520 * Added new local command FILE to the Irssi SILC Client.
1521 It is used to perform the file transfer. It has subcommands
1522 SEND, RECEIVE, SHOW and CLOSE. Affected files
1523 irssi/src/silc/core/client_ops.c,
1524 irssi/src/silc/core/silc-server.[ch].
1526 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Relay the SILC_PACKET_FTP in the server. Affected files
1529 silcd/server.c and silcd/packet_receive.c.
1531 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Renamed silc_file_read and silc_file_write to functions
1534 silc_file_readfile and silc_file_writefile. Added function
1535 silc_file_open and silc_file_close. Affected files
1536 lib/silcutil/silcutil.[ch].
1538 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Resolve the client info when received private message or
1541 channel message for a client which nickname we don't know.
1542 Affected files lib/silcclient/client_prvmsg.c and
1543 lib/silcclient/client_channel.c.
1545 * Do not crash in /KEY if client is not connected. Affected
1546 file irssi/src/silc/core/silc-channels.c.
1548 * Added SilcClientStatus field to the SilcClientEntry in the
1549 lib/silcclient/idlist.h.
1551 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1552 is incomplete and is being resolved, it won't be resolved
1555 Make sure also that USERS command reply does not resolve
1556 twice information. Affected file is
1557 lib/silcclient/command_reply.c.
1559 Make sure that silc_client_get_clients_by_list does not
1560 resolve twice same information.
1562 * Check for valid client->id in the silc_server_free_client_data.
1563 Affected file silcd/server.c.
1565 * Fixed /GETKEY nick@server not to crash if the server entry
1566 is not found. Affected file lib/silcclient/command.c.
1568 * Fixed the silc_server_check_cmode_rights to check the
1569 requested modes correctly. Affected file silcd/command.c.
1571 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Better checks for non-printable chars in nick added.
1574 Affected file silcd/command.c.
1576 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Call the silc_server_udpate_servers_by_server in the
1579 primary router that comes back online in the backup resuming
1580 protocol. Otherwise it routes packets wrong. Affected file
1581 silcd/server_util.[ch], silcd/server_backup.c.
1583 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1586 lib/silcutil/silcbuffmt.[ch].
1588 * Redefined the SILC packet header to include the padding
1589 length. Affected file lib/silccore/silcpacket.[ch].
1591 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1592 length for maximum padding up to 128 bytes). Affected
1593 file lib/silccore/silcpacket.h.
1595 * Removed all backwards support for old 0.5.x MAC thingies.
1596 The SILC packet header change makes it impossible to be
1597 backwards compatible.
1599 * Send the ENDING packet with timeout in the backup resuming
1600 protocol. This is to assure that all routers has connected
1601 to the primary router. Affected file silcd/server_backup.c.
1603 * Changed the RNG to take the first IV from random data. It
1604 used to take it from zero actually. Changed the RNG also
1605 to use /dev/urandom during session. /dev/random is used
1606 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1608 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Changed the SILC packet header to have the first two bytes
1611 (the packet length) encrypted. Affected files aroung the
1612 code tree, lib/silccore/silcpacket.[ch]. Removed the
1613 SilcPacketCheckDecrypt callback. It is not needed anymore
1614 since the silc_packet_receive_process will determine now
1615 whether the packet is normal or special.
1617 * Implemented the unidirectional MAC keys. Affected files
1618 lib/silcske/silcske.c, silcd/protocol.c and
1619 lib/silcclient/protocol.c.
1621 * Implemented the packet sequence number to the MAC computation.
1622 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1623 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1624 lib/silcclient/protocol.c.
1626 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Allow backup router to announce servers. All servers
1629 announced by backup router are added to the global list
1630 automatically. Update hte server's socket to our primary
1631 router also when backup router announces a server.
1632 Affected file silcd/packet_receive.c.
1634 * Do not update the client->router in the function
1635 silc_server_udpate_clients_by_server if the client is on
1636 global list. We might fail to find any specific server
1637 for locally connected clients and local cell clients. They
1638 should still use the `from' and not `to' as client->router.
1639 This fixes backup router resuming protocol. Affected file
1640 silcd/server_util.c.
1642 * Decrease channel statistics count only if the channel
1643 deletion worked. Affected files are silcd/server.c and
1644 silcd/server_util.c.
1646 * Added silc_server_update_servers_by_server to update origin
1647 of all server entries. Used during backup router protocol.
1648 Affected files silcd/server_util.[ch], silcd/server.c. and
1649 silcd/backup_router.c.
1651 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1652 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1653 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1654 lib/silccrypt/silchmac.c.
1656 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Assure that router cannot reroute the same channel message
1659 to the sender. Affected file silcd/packet_receive.c.
1661 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Made better checks that the channel message is not sent
1664 to the router it came from. Affected file is
1665 silcd/packet_send.c. Fixed memory leak too.
1667 * Announce informations for incoming router connection, but
1668 only after checking if it is replaced by backup router.
1669 Affected file silcd/packet_receive.c.
1671 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Fixed the backup resuming protocol to work in multiple
1674 router environment. Affected file silcd/server_backup.c.
1676 * Route packet only to one router in the function
1677 silc_server_packet_send_to_channel. Affected file is
1678 silcd/packet_send.c.
1680 * Fixed silc_server_send_notify_dest to set the broadcast
1681 flag. Fixed the silc_server_send_notify_topic to actually
1682 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1683 Affected file silcd/packet_send.c.
1685 * Changed the SFTP Filesystem interface. Changed the
1686 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1687 the filesystem operation function. The SilcSFTPFilesystem
1688 is now a context that is allocated by all filesystem allocation
1689 functions and it already includes the operations structure
1690 and filesystem specific context. It is given as argument
1691 now to the silc_sftp_server_start. This made the interface
1692 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1693 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1695 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Changed the backup router adding and getting interfaces
1698 in the server. The router that will be replaced by the
1699 specified backup router is now sent as argument. Affected
1700 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1703 * Added silc_net_addr2bin_ne to return the binary form of
1704 the IP address in network byte order. Affected files
1705 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1707 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Check for existing server ID in silc_server_new_server
1710 and in silc_server_connect_to_router_final and remove the
1711 old entry if it exists. Affected file silcd/packet_receive.c,
1714 * Send the channel message always to only one router, either
1715 in upstream or downstream. Affected file is
1716 silcd/packet_send.c.
1718 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Wrote the definition of the backup resuming protocol to the
1721 protocol specification.
1723 * Removed one redundant channel key generation from normal
1724 server during joining procedure. Removed one redundant
1725 channel key sending from server to router during joining
1726 procedure. Affected file silcd/command.c.
1728 * Made minor bugfixes to the backup router resuming protocol.
1729 Affected file silcd/server_backup.c, server.c.
1731 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Added --disable-asm configuration option. Affected files
1734 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1737 * Implemented the backup resuming protocol that is used to
1738 resume the primary router position in the cell after the
1739 primary router comes back online. Affected files
1740 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1741 and silcd/server_util.[ch].
1743 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Sleep two (2) seconds after sending QUIT command to server.
1746 Affected file lib/silcclient/command.c.
1748 * Assure that if outgoing data buffer is pending do not force
1749 send any data. Affected file silcd/packet_send.c.
1751 * Assure that if outgoing data buffer is pending do not force
1752 send any data. Affected file lib/silcclient/client.c.
1754 * Implemented the backup router support when the primary router
1755 goes down. The servers and routers can now use the backup
1756 router as new primary router without loosing connectivity.
1758 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1761 in the server to indicate disabled entry. All data read
1762 from the connection will be ignored and no data is sent
1763 for entry that is disabled. Affected files are
1764 silcd/idlist.h, silcd/server.c.
1766 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Created SFTP client and server test programs in the
1769 lib/silcsftp/tests directory.
1771 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Implemented memory filesystem (virtual filesystem) for
1774 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1777 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Implemented the SFTP (SSH File Transfer Protocol) to the
1780 lib/silcsftp. It includes SFTP client and SFTP server
1783 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Moved lib/silccore/silcprotocol.[ch] to the
1786 lib/silcutil library.
1788 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1789 take variable argument list pointer as argument. Affected
1790 file lib/silcutil/silcbuffmt.[ch].
1792 * Added silc_buffer_set function that is used to set data
1793 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1794 Affected file lib/silcutil/silcbuffer.h.
1796 * Changed various routines in the core library to use the new
1797 silc_buffer_set instead of allocating new buffer only for
1800 * Added 64-bit value formatting and unformatting support to the
1801 silc_buffer_[un]format routines. Affected file is
1802 lib/silcutil/silcbuffmt.[ch].
1804 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1805 to includes/bitmove.h.
1807 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1809 * Fixed channel user mode saving in client library. Affected
1810 file lib/silcclient/command[_reply].c.
1812 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Defined the file transfer to the SILC Protocol. Added
1815 new packet type SILC_PACKET_FTP and defined File Transfer
1816 Payload. The mandatory file transfer protocol is SFTP
1817 (SSH File Transfer Protocol). Affected file in addition
1818 of the internet draft is lib/silccore/silcpacket.h.
1820 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1821 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1822 is used as part of backup router protocol when the primary
1823 router of the cell is back online and wishes to resume
1824 the position as primary router.
1826 * Redefined the MAC generation keys in the protocol. The
1827 same key is not used anymore in both direction. Both
1828 direction will now use different keys for sending and
1829 receiving. This fixes a potential security flaw. This
1830 change causes incompatibilities in the protocol.
1832 * Redefined also the MAC computation from the packet.
1833 An packet sequence number is now added to the MAC
1834 computation. This prevents possible replay attacks against
1835 the protocol. This change too causes incompatibilities
1838 Added `sequence' field to the SilcPacketContext to hold
1839 the current sequence number for the packet.
1841 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Added `created' field to the SilcIDListData in the file
1844 silcd/idlist.h to indicate the time when the entry was
1847 * Added `created' field to the SilcChannelEntry too. Affected
1848 file silcd/idlist.h.
1850 * Added `creation_time' aguments to all the announcement functions
1851 in the server. If it is provided then only the entries that
1852 was created after the provided time frame are actually
1853 announced. Affected file silcd/server.[ch].
1855 * The protocol says that the Channel ID's IP address must be
1856 based on the router's IP address. Added check for this in
1857 the silc_server_new_channel when processing incoming New Channel
1858 Payload. Affected file silcd/packet_receive.c.
1860 * Print out the correct version with --version in SILC client.
1861 Affected file irssi/src/silc/core/silc-core.c.
1863 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Fixed WHOWAS command to check for completnes of the client
1866 entry always, not just when the command is coming from client.
1867 Affected file silcd/command.c.
1869 * Added new function silc_server_packet_queue_purge to purge the
1870 outgoing data queue to the network. After the function returns
1871 it is guaranteed that the outgoing packet queue is empty.
1872 Affected file silcd/packet_send.[ch].
1874 * Purge the outgoing packet queue in the rekey protocol's final
1875 callback to assure that all rekey packets go to the network
1876 before quitting the protocol. Affected file silcd/server.c.
1878 * Added silc_client_packet_queue_parse as similar function as
1879 in server to the client library. The affected file is
1880 lib/silcclient/client.c.
1882 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Splitted silcd/server.c and created silcd/server_util.[ch]
1885 for utility functions.
1887 * Added new socket flag SILC_SF_DISABLED to indicate that the
1888 connection is open but nothing can be sent to or received from
1889 the connection. Affected file lib/silcutil/silsockconn.[ch].
1890 The checking for disabled socket is checked in the low level
1891 silc_socket_write and silc_socket_read functions.
1893 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Allow only nicknames and channel names that fits into the
1896 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1898 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * When processing JOIN command reply in server check that if
1901 the channel exists in our global list we'll move it the local
1902 list. Affected file silcd/command_reply.c.
1904 * Fixed the check whether client is joined on the channel already
1905 in JOIN command. Affected file lib/silcclient/command.c.
1907 * Fixed the JOIN command reply to check whether the channel
1908 already exists. Affected file lib/silcclient/command_reply.c.
1910 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Added silc_ske_status_string to map the SKE error numbers
1913 to readable strings. The affected files are
1914 lib/silcske/silcske[_status].[ch].
1916 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Do not show the private channels on the WHOIS channel list
1919 as it is not allowed by the protocol. The affected file is
1922 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Assure that the packet length digged from the actual packet
1925 is something sensible in the silc_packet_decrypt_rest_special
1926 in lib/silccrypt/silcpacket.c.
1928 * Free and NULL the allocated pointer in silc_hmac_alloc if
1929 the HMAC allocation fails. The affected file is
1930 lib/silccrypt/silchmac.c.
1932 * Print the selected security properties to the log files in
1933 the server. Affected file silcd/protocol.c.
1935 * Add SKE's reference counter even if calling the completion
1936 callback manually. Otherwise it goes negative, although it
1937 does not cause any problems. The affected file is
1938 lib/silcske/silcske.c.
1940 * Remove the client entry with short timeout after giving the
1941 KILL command. Affected file lib/silcclient/command.c.
1943 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1944 case all found clients are already disconnected (WHOWAS would
1945 found them) in the server. Affected file silcd/command.c.
1947 * Update the last_receive (time of last data received) to be
1948 updated only when received private or channel message so that
1949 the idle time showed in WHOIS makes more sense.
1951 * Added boolean field `valid' in to the SilcClientEntry in the
1952 client library to indicate whether the entry is valid or not.
1953 This fixes the nickname change bug on channel when changing
1954 the nickname to be same than the old (like nick to Nick) the
1955 nickname formatter doesn't set the new nick anymore to Nick@host.
1956 Affected file lib/silcclient/idlist.[ch].
1958 * Now actually fixed the nickname changing on disconnection.
1959 Added new function silc_change_nick to the Irssi SILC Client.
1960 Affected file irssi/src/silc/core/client_ops.c,
1961 irssi/src/silc/core/silc-nicklist.[ch].
1963 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Check that the public key exists in the GETKEY command before
1966 trying to encode it. Affected file silcd/command.c.
1968 * Print some notifications on received public keys with GETKEY
1969 command in the Irssi SILC Client. Affected files are
1970 irssi/src/fe-common/silc/module-formats.[ch],
1971 irssi/src/silc/core/client_ops.c.
1973 * Use IDENTIFY command to resolve the server information in the
1974 GETKEY command instead of INFO command. Affected file
1975 lib/silcclient/command.c.
1977 * All command reply functions in the client library now calls
1978 the pending command reply callbacks even if an error has
1979 occurred. The server has done this a long time and now it was
1980 time to move the client library to this as well. Now all
1981 errors can be delivered back to the pending command reply
1982 callbacks if necessary. Affected files are
1983 lib/silcclient/command[_reply].[ch].
1985 * Change the nickname on disconnection back to the username
1986 because in reconnect the server will enforce it to it anyway.
1987 Affected file irssi/src/silc/core/silc-servers.c.
1989 * Fixed a config file parsing bug in the Irssi SILC client.
1990 Affected file irssi/src/silc/core/clientconfig.c.
1992 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * When printing the channel mode on JOIN, verify that the
1995 channel key and channel's HMAC are valid. Affected file
1996 irssi/src/silc/core/client_ops.c.
1998 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2001 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2002 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2004 * Removed channel key rekey task deleting from the function
2005 silc_server_save_channel_key. Affected file silcd/server.c.
2006 Added explicit timeout task context instead that is used to
2007 delete the task if we are registering a new task before the
2008 new task has elapsed.
2010 * When channel key rekey occurs the client library now saves
2011 the old channel key for a short period of time (10 seconds) and
2012 is able to use it in case some is still sending channel
2013 messages encrypted with the old key after the rekey. Affected
2014 file lib/silcclient/[idlist.h|client_channel.c].
2016 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * Added check to the silc_server_new_id_real to not accept
2019 new ID if it is the sender's own ID. Affected file is
2020 silcd/packet_receive.c.
2022 * Assure that we do not announce ourself or the one we've
2023 sending our announcements when we're router and are announcing
2024 servers to our primary router. Affected file silcd/server.c.
2026 * Fixed silc_server_command_identify_check_client to assemble
2027 correct WHOIS packet. It send corrupted WHOIS packet and
2028 caused problem with router to router connections. Affected
2029 file silcd/command.c.
2031 Fixed also silc_server_command_whois_check the same way
2032 as for the IDENTIFY command.
2034 * Added new SilcIDListStatus to the server in the SilcIDListData
2035 structure. The status now includes the current status of
2036 the entry (like registered, resolved etc.). Affected file
2037 silcd/idlist.[ch]. Defined a bunch of different status types
2038 as well. This replaced the old boolean registered field as well.
2040 Added resolve_cmd_ident field to the SilcClientEntry structure
2041 too so that if the entry is for example being resolved so
2042 another command may attach to the same pending command reply
2043 without requiring to resolve the same entry again. This concept
2044 should optimize the WHOIS and the IDENTIFY resolving under
2045 heavy load by taking away unnecessary resolving for entries
2046 that are being resolved already.
2048 Added support for adding multiple pending commands for one
2049 command idenfier. Affected file silcd/command[_reply].[ch].
2051 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2052 before deleting the data. Otherwise the hash table will have
2053 freed data in comparison functions. Affected file is
2054 silcd/command_reply.c.
2056 * Fixed silc_idlist_replace_client_id to add the new entry to
2057 the cache with NULL nickname. Otherwise there will be invalid
2058 memory as the nickname after the nickname is freed. Affected
2059 file silcd/packet_receive.c.
2061 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2062 saved into wrong slots because the previous number of entries
2063 was not taken into account. Affected file silcd/idlist.c.
2064 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2066 * If we are router and we receive JOIN notify to a channel that
2067 does not have any users then notified client is marked as the
2068 channel founder, as it is it. The affected file is
2069 silcd/packet_receive.c
2071 * Added to the extended hash table API's table_del_*ext functions
2072 the destructor as argument too, so that the caller can decide
2073 which destructor to use or whether to use destructor at all.
2074 Affected file lib/silcutil/silchashtable.[ch].
2076 * Fixed ID Cache purging. It actually deleted the entries from
2077 the hash table after the data was freed. The hash table ended
2078 up comparing freed memory. The affected file is
2079 lib/silccore/silcidcache.c.
2081 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Fixed Irssi SILC client's KILL command's HELP syntax.
2085 * The USERS command now resolves the detailed user information
2086 if the userinfo field is missing. Affected file is
2087 lib/silcclient/command_reply.c.
2089 * Do not print error in silc_file_read if the read file does
2090 not exist. Just silently return NULL. Affected file is
2091 lib/silcutil/silcutil.c.
2093 * Fixed the silc_log_output to not wine about NULL filename
2094 and to not create some bogus " " filename. Affected file is
2095 lib/silcutil/silclog.c.
2097 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed various printing bugs on the user interface in the
2100 Irssi SILC Client. Minor changes that were forgotten from
2103 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Fixed the configure.in.pre and the compilation and distribution
2106 environment to support the new autoconf 2.52. That version is
2107 now required to compile the CVS trunk.
2109 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2112 to generally parse user@fqdn format strings. Affected file
2113 lib/silcutil/silcutil.c.
2115 * Added nickname_format and nickname_force_format fields to the
2116 SilcClientParams structure. The first one defines the format
2117 for the nicknames that the library will enforce if the receives
2118 multiple same nicknames. The second one is boolean value and
2119 can be used to force the library to always enforce the format
2120 to the nicknames regardles whether there are multiple nicknames
2121 or not. This configurable formatting was employed to flexibly
2122 support accessing multiple nicknames from the user interface.
2123 The userinterface can now set the nicknames to what ever format
2124 they prefer. Affected file lib/silcclient/silcapi.h.
2126 Added function silc_client_nickname_format to the file
2127 lib/silcclient/idlist.c. It performs the nickname formatting.
2129 Added new field `hostname´ to the SilcClientEntry context.
2130 It holds the hostname of the client. Affected file is
2131 lib/silcclient/idlist.h.
2133 * Irssi SILC Client sets the nicknames in nick@hostn format.
2134 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2135 irssi/src/silc/core/silc-core.c.
2137 The WHOIS printing now also shows both the real nickname and
2138 the formatted nickname so that user knows how to access the
2139 user if there are multiple same nicknames cached. Affected
2140 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2141 printing formatting too to take the hostname now as a separate
2142 argument. The Affected file is
2143 irssi/src/fe-common/silc/modules-formats.[ch].
2145 * Changed the silc_client_get_clients_local to accept the formatted
2146 nickname as argument. It accepts the real nickname too but the
2147 formatted nickname can be used to find the true entry from
2148 multiple entries. Affected file lib/silcclient/silcapi.h and
2149 lib/silcclient/idlist.c.
2151 * Added nickname_format_parse field to the SilcClientParams.
2152 It is a callback function provided by the application to parse
2153 the nickname out of the formatted nickname string. The library
2154 calls it to get the nickname from the formatted string. Since
2155 the application generally knows better the format of the nickname
2156 string it parses it instead of the library, even though library
2157 encodes the formatted string. If the callback function is not
2158 provided then the library will use the string as is. The
2159 affected file is lib/silcclient/silcapi.h.
2161 * All the nickname strings passed to the client library in
2162 commands are now expected to be formatted nickname strings.
2163 If the command does not support the formatted nickname string
2164 it will assume that the sent string is the actual nickname.
2165 Affected file lib/silcclient/command.c.
2167 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Added public key authentication support to OPER and SILCOPER
2170 commands in the client library. Affected file is
2171 lib/silcclient/command.c.
2173 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Changed the get_auth_methdod client operation to be asynchronous.
2176 It can be async if the application resolves the authentication
2177 method from the server during the negotiation. Added new
2178 SilcGetAuthMeth completion callback that the application will
2179 call after resolving the authentication method.
2181 Added function silc_client_request_authentication_method that
2182 the application can use to resolve the authentication method
2183 from the server. Added also SilcConnectionAuthRequest callback
2184 that the library will call after the server has replied. The
2185 application can call this function if it does not know the
2186 current authentication method.
2188 Affected files are lib/silcclient/client.c and
2189 lib/silcclient/silcapi.h.
2191 * The Irssi SILC client now automatically resolves the authentication
2192 method incase any configuration information is not present (and
2193 currently there never is). The affected file is
2194 irssi/src/silc/core/client_ops.c.
2196 * Fixed public key authentication from the client library.
2197 Affected file lib/silcclient/protocol.c. Changed also the
2198 protocol specification about the public key authentication in
2199 the connection authentication protocol. The actual data to be
2200 signed is now computed with a hash function before signing.
2202 * Fixed the public key authentication from the server as well.
2203 Affected file silcd/protocol.c.
2205 * Removed the mlock()'s from the memory allocation routines.
2206 Affected file lib/silcutil/silcmemory.c. The ./configure does
2207 not check anymore for the mlock(). Affected file is
2210 * Fixed USERS command in server to allow the execution of the
2211 command for private and secret channels if the client sending
2212 the command is on the channel. Affected file silcd/command.c.
2214 * Fixed silc_client_get_clients_local to return the clients
2215 count correctly. It could return wrong value. Affected file
2216 lib/silcclient/idlist.c.
2218 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2221 types. The assembler optimizations seemed not to like 64-bit
2222 data types. The assmebler optimizations thus are now enabled
2223 also for BSD systems as opposed to only enable them for Linux.
2225 * Do not check for threads at all on BSD systems. Affected
2226 file configure.in.pre.
2228 * Removed -n and -h options from the Irssi SILC Client since
2229 they are not used in silc.
2231 * Fixed the prime generation to assure that the first digit
2232 of the generated random number is not zero since our conversion
2233 routines does not like number strings that starts with zero
2234 digit. If zero digit is seen the random number is regenerated.
2235 This caused some corrupted RSA keys when the zero first digit
2236 was met. Affected file lib/silcmath/silcprimegen.c.
2238 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Fixed WIN32 configuration in the ./configure script.
2241 Fixed to include xti.h on environments that has it.
2242 Patches by Carsten Ilchmann and andrew.
2244 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Changed the silc_id_create_client_id to be collision
2247 resistant. It is now assured that there cannot be created
2248 two same client ID's. I suspect that some weird bugs in
2249 the server were actually caused by duplicate Client IDs.
2250 Affected file silcd/serverid.[ch]. A router receiving
2251 new ID now also assures and informs the sending server
2252 if the ID caused collision.
2254 * Changed the silc_id_create_channel_id to also assure that
2255 there are no collisions.
2257 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Statement about ignoring the Mutual Authentication flag when
2260 performing rekey with PFS was a bit misleading. It is ignored
2261 if it was set in the initial negotiation, it cannot be even
2262 set in the rekey. Fixed in the ke-auth draft. Started the
2263 new versions of the protocol drafts in the doc/.
2265 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Fixed a bug in silc_client_command_identify_save when saving
2268 new channel information. The channel name was no duplicated
2269 and caused crash on exit. Affected file is
2270 lib/silcclient/command_reply.c.
2272 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Fixed the getkey command handling in the server. Send just
2275 empty OK reply to the sender if the key could not be fetched
2276 (but everything else was ok, like the key just was not available).
2277 Changed the public key parameter to optional in the protocol
2278 specs so that empty OK reply can be sent. Affected file
2281 Added a message to Irssi SILC client to tell to user if the
2282 server did not return a public key.
2284 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Fixed a channel key regeneration bug. It registered new
2287 timeout tasks exponentially until all system resources were
2288 used. Affected file silcd/server.c.
2290 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Added the SILC Document generator to the scripts/silcdoc.
2293 It can be used to generate the Toolkit Reference Manual out
2294 of the source tree. Internally it will also use the RoboDoc
2295 generator now imported in util/robodoc.
2297 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Added couple of return's in rekey protocol if error orccurred
2300 during the protocol. The execution must be terminated.
2301 Affected file silcd/protocol.c. Also, terminate the protocol
2302 always with timeout.
2304 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * The client's Client ID was created initally from the wrong
2307 nickname (it could have been in format nick@host) in the
2308 silc_server_new_client. Affected file silcd/packet_receive.c
2310 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Added some SILC_LOG_ERROR's to various error conditions
2313 if client could not be added to ID cache. Affected files
2314 silcd/packet_receive.c and silcd/server.c.
2316 * When client's sock->user_data is freed, NULL also the
2317 client->router and client->connection pointers. Added check
2318 for these pointers being NULL to various places around the
2319 code. Affected file silcd/server.c.
2321 * Added client->data.registered == TRUE checks to various
2322 places around the code to assure that unregistered client's
2323 are not handled when it is not allowed. Affected file
2326 * Added `bool registered' fields to all
2327 silc_idlist_[server|client]_get_* routines to indicate whether
2328 the fetched client needs to be registered or not. Affected
2329 file silcd/idlist.[ch].
2331 * Add your own entry as registered to the ID cache in the
2332 server. Affected file server.c.
2334 * Fixed a bug in silc_server_new_server. The SilcServer was
2335 set as the new server's context instead of SilcServerEntry.
2336 This naturally caused some weird bugs.
2338 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Do not delete the channel rekey task when adding it
2341 for in silc_server_create_channel_key.
2343 * Changed the silc_server_create_channel_key to return
2344 TRUE or FALSE to indicate the success of the channel key
2347 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Fixed MSVC++ project files and added missing files to
2350 Makefiles under win32/.
2352 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Do not add TCP_NODELAY flag if the operating system
2355 does not have it defined. Affected files are
2356 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2358 * Fixed buffer overflow from Irssi SILC Client. Affected
2359 file irssi/src/fe-common/core/themes.c.
2361 * Fixed double free in client library in the file
2362 lib/silcclient/client.c when disconnecting from server.
2364 * Applied double free patch from cras to Irssi SILC client.
2365 Affected files irssi/src/core/[modules/expandos].c
2367 * Fixed the disconnection handling to Irssi SILC Client.
2368 The application must call silc_client_close_connection
2369 in ops->connect client operation in case of failure of
2370 the connection. Affected file is
2371 irssi/src/silc/core/client_ops.c.
2373 * Do not set sock->protocol to NULL in the function
2374 silc_client_close_connection after executing the protocol's
2375 final callback since the sock might not be valid anymore.
2376 Affected file lib/silcclient/client.c.
2378 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Do not enable SILC_THREADS if the linking with libpthread
2381 did not happen. Affected file configure.in.pre.
2383 * Added notion to protocol specification that server must
2384 verify the sent authentication payload with CMODE when
2385 setting the channel founder key. Implemented it to the
2386 server. Affected file silcd/command.c.
2388 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Added _EXTRA_DIST SILC distribution variable to the
2391 distributions file. It is used to conditionally add extra
2392 files or directories to the specific distribution. Affected
2393 files ./prepare, Makefile.am.pre and distributions.
2395 Removed the `_' from the start of the distribution names.
2398 * Added README.WIN32 for instructions to compile the Toolkit
2401 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Fixed a double free in disconnection in the server. Affected
2404 file is silcd/server.c.
2406 * Fixed the lib/silcske/groups.c to work now also with GMP
2407 MP library. The string conversion did not work when using
2408 specific base and the base is indicated in the string as well.
2410 * Created win32/ directory which now includes MSVC++ specific
2411 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2412 It will appear only in the toolkit distribution
2414 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Changed the key material distribution function in case when
2417 the hash output is too short. The data is now concatenated
2418 a bit differently than it used to. Made the change to the
2419 SKE protocol specification.
2421 * Added better GMP detection to configure.in.pre. A patch
2424 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Fixed a minor bug in SKE that might cause some problem on
2427 some platforms. Affected file lib/silcske/silcske.c.
2429 * Added the cookie checking for initiator in the SKE. It checks
2430 that the responder returns the sent cookie unmodified. The
2431 affected file is lib/silcske/silcske.c. Added new SKE
2432 error type INVALID_COOKIE that can be sent during the
2433 negotiation. Fixed some memory leaks as well.
2435 * Added the "invalid cookie" error message to Irssi SILC client's
2438 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Added `task_max' field to the SilcClientParams to indicate
2441 the maximum tasks the scheduler can handle. If set to zero,
2442 default values are used. Affected file lib/silcclient/silcapi.h.
2444 * Fixed memory leaks in silc_client_close_connection. Affected
2445 file lib/silcclient/client.c.
2447 * Added silc_client_del_client_entry to client library to free
2448 all memory of given client entry. Affected file is
2449 lib/silcclient/idlist.[ch].
2451 * Added new functions silc_client_del_channel and
2452 silc_client_del_server to delete channel and server entries.
2453 Affected file lib/silcclient/[silcapi.h/idlist.c].
2455 * Removed silc_client_del_client_by_id from silcapi.h.
2457 * Fixed the INFO command to return the server's own info
2458 correctly when querying by Server ID. Affected file is
2461 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Removed the non-blocking settings in WIN32 code in the
2464 silc_sock_[read/write] and added SleepEx instead. Affected
2465 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2466 of input data is now checked with FIONREAD and ioctlsocket.
2468 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Call silc_schedule_task_del_by_context in the
2471 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2472 Affected file lib/silccore/silcprotocol.c.
2474 * Call silc_protocol_cancel for active protocols in the
2475 silc_server_close_connection if the funtion
2476 silc_server_free_sock_user_data has not been called.
2477 Affected file silcd/server.c.
2479 * Generic tasks cannot be deleted using the del_by_fd
2480 task deleting function since generic tasks does not match
2481 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2483 * Added a notion to SILCOPER help file that the SILCOPER works
2484 only on router server, not on normal server.
2486 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Added for WIN32 support for the new scheduler as well.
2489 Affected file lib/silcutil/win32/silcwin32schedule.c.
2491 * Fixed the SHA1 implementation to work on various platforms.
2493 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2496 API. It is part of the scheduler now. Everything else is
2497 as previously but some functions has changed their names.
2498 Checkout the lib/silcutil/silcschedule.h for the interface.
2499 Updated all applications to use the new interface. Affected
2500 files are lib/silcutil/silcschedule.[ch].
2502 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Found a bug in the SKE implementation. The HASH value,
2505 specified by the protocol, was not computed correctly. The
2506 public key of the responder was not added to the computation
2507 even though it is mandatory. Affected file lib/silcske/silcske.c.
2508 This unfortunately causes incompatibilities with older
2509 clients and servers.
2511 * Added WIN32 specific network init and uninit functions:
2512 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2513 the Winsock2. Affected file lib/silcutil/silcnet.h and
2514 lib/silcutil/win32/silcwin32net.c.
2516 * Set the socket always to nonblocking mode on WIN32 after
2517 reading data or writing data. Affected file is
2518 lib/silcutil/win32/silcwin32sockconn.c.
2520 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Fixed various compilation problems under WIN32. Affected
2523 files lib/silcutil/win32/silcwin32thread.c and
2524 lib/silcutil/win32/silcwin32schedule.c.
2526 * Removed all _internal.h #includes from public header
2527 files. Internal headers must never be included from
2530 Removed also the lib/silcske/payload_internal.h file.
2532 * All include files that may be needed (public and some others
2533 included by the public headers) by application developers are
2534 now copied to the ./includes directory. It does not copy any
2535 internal headers. Affected file Makefile.defines.pre and all
2536 Makefile.am's under lib/ and subdirs.
2538 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Do not change the ~/.silc directory's permissions automatically.
2541 Affected file irssi/src/silc/core/clientutil.c.
2543 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Do not cancel the protocol in silc_server_close_connection
2546 it might cause recursion. Now cancelled in the function
2547 silc_server_free_sock_user_data. Affected file silcd/server.c.
2549 * Fixed the silc_server_remove_clients_by_server to regenerate
2550 the channel keys correctly finally. Added also new function
2551 silc_server_remove_clients_channels to actually do it.
2552 Affected file silcd/server.c.
2554 * Fixed the silc_server_new_channel to not crash by giving
2555 wrong router to the new channel. Affected file is
2556 silcd/packet_receive.c.
2558 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2561 which is given as argument to the silc_client_alloc now.
2562 It can be used to configure the client and set various parameters
2563 that affect the function of the client.
2565 * The USERS command in server did not check whether the channel
2566 is private or secret. Affected file silcd/command.c.
2568 * Added new argument to the USERS command in protocol specification.
2569 The USERS command now can take the channel name as argument
2570 as well. Added support for this in client and server and
2571 updated the protocol specs.
2573 * Completed the GETKEY command in client. It can be now used
2574 to fetch also servers public key not only some clients.
2575 Affected files lib/silcclient/command[_reply].c.
2577 * Added silc_client_get_server to return server entry by the
2578 server name. Affected files lib/silcclient/silcapi.h and
2581 * Redefined the IDENTIFY command in protocol specification to be
2582 more generic. It now can be used to query information about
2583 any entity in the SILC Network, including clients, servers and
2584 channels. The query may be based either the entity's name
2585 or the ID. Added support for this in both client and server.
2587 Affected files silcd/command.c and lib/silcclient/command.c
2588 and command_reply.c.
2590 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2591 the _from_client and _from_server functions. Affected file
2594 * Added silc_client_get_channel_by_id_resolve to the file
2595 lib/silcclient/silcapi.h to resolve channel information by
2596 its ID. Added also silc_client_get_channel_by_id that
2597 does not resolve it from the server.
2599 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Added SilcServerEntry context into the client library
2602 to represent one server. The INFO command now allocates
2603 these to save the resolved server info. For now on the
2604 client library will also keep information about servers,
2605 connected and resolved with INFO.
2607 The INFO command now allocates the SilcServerEntry context
2608 and saves the server info there. The COMMAND_REPLY in
2609 the INFO now returns the parameters to application in
2610 same order as defined in the protocol specification.
2612 The entries are cached in the client->server_cache.
2614 * The INFO command is now issued after received the Client ID
2615 from the server. Affected file lib/silcclient/client.c.
2617 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2618 to the application as the mode changer might be server.
2619 It is guaranteed that NULL is not returned anymore to the
2620 application. Affected file lib/silcclient/client_notify.c.
2622 The ID Type is now also passed to the application so that
2623 it can check whether the returned entry is SilcClientEntry
2626 Added new function silc_client_get_server_by_id to return
2627 the server entry by ID. Affected files are the
2628 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2630 * Do not create the channel in the Irssi SILC Client when issuing
2631 the JOIN command but when received the sucessful JOIN command
2632 reply. Otherwise the channel might get created even though we
2633 could not join it. The Affected file is
2634 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2636 * Fixed a channel joining bug in router. The router must also
2637 check the channel modes, invite and ban lists etc. when serving
2638 the JOIN command sent by normal server. Affected file is
2639 silcd/command.c. The router now resolves the client's
2640 information from the server who sent the JOIN command if it
2641 does not know it, and processes the JOIN command only after
2644 * Changed the SilcCommandCb to take new argument; void *context2.
2645 Affected file lib/silccore/silccommand.h
2647 The second argument in the command callbacks in the server now
2648 includes the SilcServerCommandReplyContext if the command was
2649 called as pending command callback from the command reply.
2650 Otherwise it is NULL. When called as pending the status of the
2651 command reply will be checked and if it was erronous the
2652 error will be sent to the original sender of the command.
2653 This way the client always receives the error messages even
2654 though the server was actually the one who received the error
2655 when it resent the command to router, for example. Affected
2656 files silcd/command[_reply].[ch].
2658 * Fixed sending WHOWAS command's error message to client if
2659 the requested client could not be found. It was missing.
2662 * Changed the CMODE and CUMODE commands reply arguments in the
2663 protocol specification. The Channel ID is now sent in both
2664 of the commands to identify the channel. Implemented this
2665 new feature to the client and server. Affected files
2666 lib/silcclient/command_reply.c and silcd/command.c.
2668 * Made better checks for invite and ban lists in the JOIN
2669 command in server. Affected file silcd/command.c.
2671 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * The server now performs the incoming host IP/DNS lookup
2674 using the silc_socket_host_lookup and thus does not block
2675 the server anymore. Affected file silcd/server.c.
2677 * Completed the multi-thread support for SILC Scheduler in
2678 the lib/silcutil/silcschedule.c.
2680 * Fixed the configure.in.pre to detect the pthread correctly
2683 * Fixed a deadlock in silc_task_queue_wakeup in the file
2684 lib/silcutil/silctask.c.
2686 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Added new function silc_schedule_wakeup that is used in
2689 multi-threaded environment to wakeup the main thread's
2690 schduler. It needs to be used when a thread adds a new task
2691 or removes a task from task queues. After waking up, the
2692 scheduler will detect the task queue changes. If threads
2693 support is not compiled in this function has no effect.
2694 Implemented the wakeup mechanism to both Unix and WIN32
2695 systems. Affected files are lib/silcutil/silcschedule.[ch],
2696 lib/silcutil/unix/silcunixschedule.c and the
2697 lib/silcutil/win32/silcwin32schedule.c.
2699 * Added new function silc_task_queue_wakeup to wakeup the
2700 scheduler by the specified task queue. Affected file
2701 lib/silcutil/silctask.[ch].
2703 * The silc_socket_host_lookup_start now wakes up the scheduler
2704 after adding the timeout task. Affected file is
2705 lib/silcutil/silcsockconn.c.
2707 * The silc_socket_host_lookup is synchronous now if the threads
2708 support is not compiled in. However, the callback is still
2709 called asyncronously through the scheduler, anyway. Affected
2710 file lib/silcutil/silcsockconn.c.
2712 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Added new function silc_socket_host_lookup to perform
2715 asynchronous IP and FQDN lookups for the socket connection.
2716 Affected files lib/silcutil/silcsockconn.[ch].
2718 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2721 that may or may not compile the mutex support in.
2723 Changed the silc_mutex_alloc interface. It allocates the
2724 mutex now to the sent pointer and returns TRUE or FALSE.
2726 Affected file lib/silcutil/silcmutex.h.
2728 * Wrote the SILC Task Queue interface to support multi-threads.
2729 Affected file lib/silcutil/silctask.[ch].
2731 * Wrote the SILC Scheduler to support multi-threads. Affected
2732 file lib/silcutil/silcschedule.c.
2734 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2737 in lib/silcutil/win32/.
2739 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Defined SILC Mutex API and SILC Thread API and implemented
2742 them for Unix. Affected files are
2743 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2744 lib/silcutil/unix/silcunixmutex.c and
2745 lib/silcutil/unix/silcunixthread.c.
2747 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Fixed the silc_server_remove_clients_by_server's channel
2750 key re-generation. The hash table handling was incorrect
2751 and would not work with many channels. Affected file is
2754 * Fixed some memory leaks around the server code.
2756 * Rewrote the silc_server_get_users_on_channel to support IPv6
2757 based Client ID's. Affected file silcd/server.c.
2759 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2760 specification. However, a separate document must be written
2761 to define the detailed signing procedure and the payload
2762 associated with the flag. Defined the flag to the
2763 lib/silccore/silcchannel.h as well.
2765 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Changed the dynamic tables to static size tables in the
2768 lib/silccrypt/silchmac.c.
2770 * Removed GCC dependencies from the code. A patch by cras.
2772 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Do not show the error "Error receiving packet bla bla"
2775 in server if it really was not an error (-2 means that reading
2776 is pending). Affected file silcd/server.c.
2778 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed a possible crash in silc_server_remove_clients_by_server
2781 in silcd/server.c. Fixed there also some memory leaks.
2783 * Fixed the silc_idlist_replace_client_id. It could replace
2784 wrong key in the hash table. Affected file silcd/idlist.c.
2786 * Do not check whether there are global users on the channel
2787 if the channel->global_users is FALSE. Affected functions
2788 silc_server_remove_from_one_channel and
2789 silc_server_remove_from_channels in silcd/server.c. Also,
2790 do not check if the removed client is local as we can be
2791 sure that global client was not removed from the channel
2792 and checking for global users is not needed.
2794 * The silc_server_remove_clients_by_server now re-generates
2795 the channel keys correctly for those channels that had
2796 clients removed from them. Affected file silcd/server.c.
2798 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Found the reason of random crashes in the server. We weren't
2801 ignoring the SIGPIPE signal (which can be sent in write())
2802 and it crashed the server. Affected file silcd/silcd.c.
2804 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Assure that sock->user_data is not NULL in the function
2807 silc_server_packet_send in silcd/packet_send.c.
2809 * Disconnect the remote connection if it could not be added
2810 to any ID lists in the server. The affected file is
2813 * Check in silc_server_packet_send[_real/dest] that the
2814 socket is not disconnecting and ignore the data if it is.
2815 Affected file silcd/packet_send.c.
2817 * Define inline to __inline on native WIN32 compilation.
2818 Affected file includes/silcwin32.h.
2820 * Added some explicit type casts for inline code since MSVC
2821 require them. Affected files lib/silcutil/silcbuffer.h,
2822 lib/trq/silcdlist.h and lib/trq/silclist.h.
2824 * Print warning in log files from now on if the packet
2825 decryption fails. Affected file silcd/server.c.
2827 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Changed the `say' client operation's interface to accept
2830 new `type' argument to indicate the type of the message sent
2831 by the library. The application may filter the library's
2832 messages according the type. The affected file is the
2833 lib/silcclient/silcapi.h.
2835 * Added two new functions to lib/silcclient/silcapi.h:
2836 silc_client_del_client and silc_client_del_client_by_id.
2837 Affected file lib/silcclient/idlist.c.
2839 * Moved the clientincludes.h from includes/ to silc/ and
2840 serverincludes.h from includes/ to silcd/.
2842 * The modes for the CMODE and CUMODE are now passed as
2843 uint32 for application with COMMAND_REPLY. The affected
2844 file is lib/silcclient/command_reply.c.
2846 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * /WHOIS without arguments shows client's own information.
2849 Affected file lib/silcclient/command.c.
2851 * Changed PING to not accept any arguments. The specs
2852 says that client can ping only the connected server so
2853 requiring an argument is not needed. Affected file is
2854 lib/silcclient/command.c.
2856 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Fixed a fatal bug in private message sending and reception
2859 encryption and decryption when using private message keys.
2860 The implementation was incorrect and did not follow the
2861 specification. It causd that some of the message were
2862 lost since it did not use the sending and receiving keys
2863 as the protocol suggests. This has been fixed and will cause
2864 incompatibilities with older clients when sending private
2865 message encrypted with private message keys. Affected files
2866 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2867 and various other in Irssi SILC Client.
2869 Added `responder' boolean argument to the functions
2870 silc_client_add_private_message_key[_ske] to indicate when
2871 the key is added as responder or initiator of the key
2874 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Removed the silc_ske_check_version function and created
2877 a SilcSKECheckVersion callback. Added also a function
2878 silc_ske_set_callbacks that is now used to set all SKE
2879 callbacks. The callback functions are not given to
2880 the SKE functions anymore, but this function is used to
2883 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2885 * Added `silc_version' argument to the silc_client_alloc
2886 to define the version of the application for the library.
2887 The library will use the version string to compare it
2888 against the remote host's (usually a server) version
2889 string. Affected file lib/silcclient/silcapi.h
2891 * Added the KE protocol context to Key Agreement context
2892 in client library so that we can abort the SKE if it
2893 is in process when we get timeout. Affected file is
2894 lib/silcclient/client_keyagr.c.
2896 * Do not resolve the client ID forever if it returns in the
2897 first time that such client does not exist. This was done
2898 for example with private message. Affected file is
2899 lib/silcclient/client_prvmsg.c.
2901 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Do not add regex.h for WIN32. The affected file
2904 includes/silcincludes.h.
2906 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2907 not work yet 100%. It generates the DLL's automatically
2908 when compiling with --with-win32 under cygwin.
2910 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * lib/contrib/regex.c is not compiled on WIN32.
2914 * Added silc_net_get_socket_opt function to the
2915 lib/silcutil/silcnet.h.
2917 * Added includes/silcwin32.h for WIN32 specific includes
2920 * Do not use ptime structure or any of the posix process
2921 functions on WIN32 in lib/silccrypt/silrng.c.
2923 * Added silc_gettimeofday to provide generic function
2924 for struct timeval on all platforms. Added the function
2925 to lib/silcutil/silcutil.h.
2927 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2930 library as they clearly belong there. As a plus side we
2931 can make the actual socket connection routines platform
2934 Added also new generic function silc_socket_read and
2935 silc_socket_write (that used to be silc_packet_[read/write].
2936 The implementation of these are platform specific.
2938 * Added WIN32 specific routines of silc_socket_[read/write]
2939 to lib/silcutil/win32/silcwin32sockconn.c.
2941 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Added preliminary support for native WIN32 compilation under
2944 cygwin (using the -mno-cygwin option for GCC) to the
2945 ./configure.in.pre. The --with-win32 now prepares the
2946 compilation for native WIN32.
2948 * Rewrote the SILC Scheduler interface in the file
2949 lib/silcutil/silcschedule.h. The scheduler is now context
2950 based and does not have anymore any global static scheduler.
2951 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2952 and created lib/silcutil/win32 directory for WIN32 based
2955 * Added Unix specific network routines to the
2956 lib/silcutil/unix/silcunixnet.c and the old
2957 lib/silcutil/silcnet.c includes now only generic routines.
2959 Added WIN32 specific network routines to the
2960 lib/silcutil/win32/silcwin32net.c.
2962 * Added Unix specific utility functions from the
2963 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2965 * Added WIN32 SILC Scheduler to the file
2966 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2969 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Do not handle JOIN notify in the server if the target client
2972 is not registered (idata->registered == FALSE). The affected
2973 file is silcd/packet_receive.c.
2975 * Update the nickrec->founder in event_cumode in the Irssi SILC
2976 client. Affected file irssi/src/silc/core/silc-channels.c.
2978 * Fixed the CUMODE_CHANGE notify handling in the server when
2979 server and router are announcing their clients on channels.
2980 Now the mode changes are saved and notified correctly. The
2981 affected file is /silcd/packet_receive.c.
2983 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2984 They really did not replace the cache entry in the ID Cache.
2985 Now they do that. Affected file silcd/idlist.c.
2987 * Fixed the KICK notify handling in the Irssi SILC client to
2988 update the channel records so that the kicked client does not
2989 appear to be on the channel. The affected file is
2990 irssi/src/silc/core/silc-channels.c.
2992 * Always update the conn->current_channel when executing command
2993 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2995 * Fixed the KILL notify handling in Irssi SILC client to remove
2996 the killed client on all channels.
2998 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Fixed the silc_parse_command_line to remove extra spaces
3001 from the start and end of the arguments. Affected file is
3002 lib/silcutil/silcutil.c.
3004 * Cancel and free any active protocol in the function
3005 silc_server_close_connection. Affected file silcd/server.c.
3007 * Cancel and free any active protocol in the function
3008 silc_client_close_connction. Affected file is
3009 lib/silcclient/client.c.
3011 * Do not execute the KILL command for clients that are in
3012 history (ie. they are not in the network). Affected file is
3015 * Fixed KILL notify handling, client does not crash anymore.
3016 Affected file irssi/src/silc/core/silc-channels.c.
3018 * Reduced the default packet buffer size from 2048 to 1024 in
3019 lib/silccore/silcpacket.c.
3021 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3022 counter to the SKE context that is incresed when the SKE library
3023 performs async operation outside the library. If the outside
3024 process frees the SKE context and FREED status will be set
3025 and the library will detect after the sync operation that the
3026 libary is freed. The affected files are
3027 lib/silcske/silcske[_status].[ch].
3029 * Resolve the client entry information in the function
3030 silc_client_channel_message to assure that NULL pointer is not
3031 passed as client entry to the application. */
3033 * Fixed the task timeout calculation to assure that there is
3034 never negative timeouts. The affected file is
3035 lib/silcutil/silcschedule.c.
3037 * Fixed the channel user mode notification sending in server.
3038 It was sent point-to-point to the router (or to server by router)
3039 but it needs to be destined to a channel. The routines now
3040 supports sending the channel user mode notifys to the channels
3041 when announcing clients and channels. Affected files are
3042 silcd/server.c and silcd/packet_receive.c.
3044 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3045 It did not actually replace the old channel entry in the cache.
3046 Affected file lib/silcclient/client_notify.c.
3048 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Fixed a possible crash in silc_packet_send_prepare. It now
3051 assures always that there is enough space in the buffer and
3052 at the tail area of the buffer (for MAC).
3054 Fixed the inbound buffer reallocation in silc_packet_read.
3055 It was old code and did not handle the reallocation correctly.
3058 The affected file is lib/silccore/silcpacket.c.
3060 * Fixed buffer overflow in silc_parse_nickname in the file
3061 lib/silcutil/silcutil.c.
3063 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * make install generates new server keys only if there is not
3068 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3071 Added check that if the NOREPLY is set then we will not send
3072 the away message. This avoids infinite loop of away messages
3073 if both clients are away. The affected file is
3074 lib/silcclient/client_prvmsg.c.
3076 * Fixed client crash if /NICK was given without arguments.
3077 Affected file lib/silcclient/command.c.
3079 * Server does not send the invite list in INVITE command back
3080 to the client if the list was not altered. Added this notion
3081 to the protocol spec as well. Affected file silcd/command.c.
3083 Fixed possible crash in INVITE command by checking the
3084 value of silc_server_get_client_route command.
3086 * Fixed the INVITE notify type handling. The arguments are now
3087 taken in correct order and client does not crash. The affected
3088 file is irssi/src/silc/core/silc-channels.c.
3090 Removed the "Inviting xxx to channel" message from the
3091 client library away and let the application handle it.
3092 Affected file lib/silcclient/command.c. Added that message
3093 to Irssi SILC client's message formats.
3095 * Fixed CMODE command crash in client. It now checks the
3096 amount of arguments correctly and does not crash. The affected
3097 file is lib/silcclient/command.c.
3099 * Do not create new channel automatically in silc_channels_join
3100 but check whether the channel by that name already exists.
3101 Affected file irssi/silc/core/silc-channels.c.
3103 * Do not send the SERVER_SIGNOFF to router if the disconnected
3104 entity was the router. Affected file silcd/server.c.
3106 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3107 SILC client as it was missing from there.
3109 Added the handling of the KICK notify to the Irssi SILC client
3110 as it was missing. Added "you have been kicked" message to
3111 Irssi SILC client's message modules formats.
3113 Added the handing of the KILL notify to the Irssi SILC client
3114 as it was missing. Added the kill message module formats
3117 The affected file is irssi/src/silc/core/silc-channels.c.
3119 * The router did not save the channel mode the server announced.
3120 Affected file silcd/packet_receive.c.
3122 * Fixed a possible crash in INFO command in server. If the
3123 server did not provide the server info it crashed. Affected
3124 file silcd/command.c.
3126 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Fixed the GETKEY command in the server to check also the
3129 global list. Otherwise the GETKEY would not work correctly
3130 in normal SILC server. Affected file silcd/command.c.
3132 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Fixed GETKEY crash, it crashed if the command did not succseed.
3136 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3139 is now real and not just an macro interface to GMP.
3141 Removed the entire GMP from the source tree and imported new
3142 NSS MPI library instead. Reason for removing GMP is that it is
3143 extremely large and compiles extremely slow. The NSS MPI
3144 is only a few files and compiles in less than 10 seconds.
3145 The speed is also about the same as GMP. The MPI is imported
3146 to lib/silcmath/mpi.
3148 If the system has GMP installed we will still use the GMP.
3149 If it is not then the NSS MPI will be compiled.
3151 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Merged a long nickname (127 characters long) crash bugfix from
3154 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3156 * Merged a freed memory reference bugfix from Irssi CVS tree.
3157 Affected file irssi/src/core/commands.c.
3159 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added the server's public key sving and verification to the
3162 server when performing the SKE. This was missing and the
3163 remote server's (or router's) public key was accepted without
3164 checking whether we have it previously or trust it at all.
3165 Affected file silcd/protocol.c.
3167 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Check in the silc_server_timeout_remote if protocol is active
3170 and make sure that the protocol's final callback is called so
3171 that all memory if freed. Affected file silcd/server.c.
3173 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * silc_server_whois_send_reply crashed the server if the nickname
3176 was 127 characters long. Affected file silcd/command.c.
3178 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * Added sanity check to the silc_server_new_client. If the hostname
3181 is provided inside username then check that the provided hostname
3182 really is the same as the resolved one. If the hostname was not
3183 resolved then check it from the public key. Affected file is
3184 silcd/packet_receive.c.
3186 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3187 if the server disconnected us and the connection is not valid
3188 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3190 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3191 the library to the lib/silcutil/silcutil.[ch].
3193 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Close log file after open. Affected file
3196 lib/silcutil/silclog.c.
3198 * Check whether sock == NULL in silc_client_send_packet and return
3199 if it is. Affected file lib/silcclient/silcclient.c.
3201 * Check rec->entry == NULL in the Irssi SILC Client before
3202 sending the channel message. Affecte file is
3203 irssi/src/silc/core/silc-servers.c.
3205 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Merged a splitted window bugfix from Irssi CVS tree. The
3208 affected file is irssi/src/fe-text/textbuffer-view.c.
3210 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3211 It did not print nickname.
3213 * Improved the distributions system a bit.
3215 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3218 irssi/src/fe-text/gui-window.c.
3220 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3221 to in-active server. The affected file is
3222 irssi/src/silc/core/client_ops.c.
3224 * Resolve the client in USERS command reply if the entry does
3225 not have username resolved. The affected file is
3226 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3227 command to WHOIS command to really resolve stuff. The USERS
3228 is not used any more in any critical section so WHOIS can
3229 be used even though it might be slower than IDENTIFY.
3231 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3234 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Changed the protocol API a bit more consistent in the
3237 lib/silccore/silcprotocol.[ch].
3239 * Changed the following headers to ROBODoc format:
3241 lib/silccore/silcpayload.h
3242 lib/silccore/silcprotocol.h
3243 lib/silccore/silcsockconn.h
3245 All core library headers are now formatted.
3247 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Fixed a bug in Irssi SILC client; do not show that you are
3250 server/router operator if you really are not. Affected file is
3251 irssi/src/silc/core/client_ops.c.
3253 * Renamed silc_command_free_payload to silc_command_payload_free.
3254 Affected file lib/silccore/silccommand.h
3256 * Added silcmath.h to include the prototoypes of various routines
3257 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3260 * Changed the following headers to ROBODoc format:
3262 lib/silccore/silcchannel.h
3263 lib/silccore/silccommand.h
3264 lib/silccore/silcid.h
3265 lib/silccore/silcidcache.h
3266 lib/silccore/silcmode.h
3267 lib/silccore/silcnotify.h
3268 lib/silccore/silcpacket.h
3269 lib/silcmath/silcmath.h
3271 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Added checking to the server code not to start the server if
3274 ciphers and stuff are not configured properly. Affected files
3275 silcd/serverconfig.[h] and silcd/server.c.
3277 * Changed the layout of the header files of the public interfaces
3278 in the SILC libraries. The new layout supports ROBODoc
3279 documentation tool (and some others) so that it is easy to create
3280 a library reference manual. All the other headers and source
3281 code must still follow the CodingStyle document. Also source
3282 code must not include these ROBODoc stuffs, only the headers.
3283 Furthermore, all public interface headers must now be named
3284 by using `silc' prefix, example: silcapi.h, silccipher.h.
3285 Some files were renamed due to this. All the other headers
3286 must not be used as public interfaces. I will update the
3287 CodingStyle document later. Changed following headers, so far:
3289 lib/silcclient/silcapi.h
3290 lib/silccore/silcauth.h
3291 lib/silccore/silcprivate.h
3292 lib/silccrypt/silcdh.h
3294 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Removed silc_client_packet_send_flush from the client library
3299 as it is not needed. Affected file lib/silcclient/client.[ch].
3301 * Added printing of message of unresolved authentication method
3302 to the Irssi SILC client. Added it to the module formats.
3303 Removed the same message from the client library.
3305 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Added new distribution feature, DISTLABEL. Every distribution
3308 can define own preprocessor label that can be used in the
3309 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3310 file distributions, acconfig.h.pre and prepare.
3312 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Added Makefile.defines_int to include the actual definitions
3315 for Makefile.defines.in. Tested the new distribution system,
3316 created distributions and tested installation.
3318 * Added AWAY message printing to the Irssi SILC client. Added
3319 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3321 * Added SCONNECT command to call the SILC's CONNECT command.
3322 Cannot use CONNECT directly since Irssi uses that internally.
3323 Affected file irssi/src/silc/core/silc-servers.c.
3325 Added ACTION local command. It is same as ME command but takes
3326 the channel as mandatory argument.
3328 Rewrote some of the Irssi's help files to suite for SILC
3331 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Added Makefile.defines[.in] that should for now on be included
3334 in all Makefile.am file in the source tree. That file includes
3335 all common compilation definitions for SILC source tree.
3337 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Minor changes to the ./prepare script to change the package
3340 name according the distribution name to the configure.in.
3342 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Created new distribution system. Added file `distributions'
3345 that defines all the distributions that can be created out of
3346 the SILC source tree. The ./prepare script now reads that
3347 file to determine how to prepare the distributions. The
3348 first argument to the ./prepare is the name of the distribution
3349 and second is the version of the distribution. If given
3350 without arguments it creates the default (toolkit) distribution
3351 with the default version (defined in ./prepare).
3353 All Makefile.am files that are subject to the distributions
3354 are now named as Makefile.am.pre. These are ./Makefile.am
3355 and lib/Makefile.am. Others may be changed later.
3357 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added invite list, ban list, some key management and connection
3360 error message printing to module formats in the Irssi SILC client.
3362 * Added new silc_client_set_away_message to set the away message
3363 that is back to the person who sent private message. The
3364 affected file lib/silcclient/silcapi.h and the
3365 lib/silcclient/client_prvmsg.c.
3367 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Fixed the private message sending in the Irssi SILC client,
3370 added local command KEY to the Irssi SILC client.
3372 Added key management and key agreement message formats to the
3373 irssi/src/fe-common/silc/module-formats.[ch].
3375 Added USERS (alias WHO) printing, server/router operator
3376 indication and LIST command printing to the module formats.
3378 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Fixed channel joining notify handling, cumode notify handling
3381 from Irssi SILC client.
3383 * Added SILC specific module-formats to the Irssi SILC client so
3384 that SILC specific message hilighting, colors etc is possible.
3385 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3387 Added channel mode, channel user mode, actions, notices,
3388 whois and whowas printing to the the module-formats.c.
3390 * Fixed a bug in channel deletion in the server. The channel
3391 is not left to the cache even if the channel founder auth mode
3392 is set when there are no users anymore on the channel. Affected
3393 file silcd/server.c.
3395 * The silc_net_localhost now resolves the entire hostname including
3396 the domain name. Affected file lib/silcutil/silcnet.c.
3398 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Changed the ask_passphrase client operation to be ascynchronous.
3401 It has now a completion callback and a context that the
3402 application must call after it has got the passphrase from
3403 the user. Affected files lib/silcclient/silcapi.h,
3404 lib/silcclient/protocol.c, lib/silcclient/command.c and
3407 Added SilcAskPassphrase callback that the application calls
3408 to deliver the passphrase to the library.
3410 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3411 The public key verification and especially a certificate
3412 verification is asynchronous procedure.
3414 Added new SILC_SKE_STATUS_PENDING status to indicate the
3415 request is pending and a callback will be called to finalize
3418 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3419 indicate that remote end did not send its public key (or
3420 certificate), even though we require it. Added check for this
3421 condition in the SKE. This was a security bug, now fixed.
3423 Defined new SilcSKEVerifyCbCompletion callback that is called
3424 when the verification process is completed.
3426 The affected files lib/silcske/silcske_status.h and
3427 lib/silcske/silcske.[ch].
3429 * Changed the verify_public_key client operation to be async
3430 as well. Defined SilcVerifyPublicKey callback that is used to
3431 indicate the success of the public key verification process.
3433 Changed the server and client to use the new async client
3436 * Changed the Irssi SILC client's internal scheduler to be called
3437 twice as many times as it used to be. As a result the client
3438 should be a bit faster now. Affected file is
3439 irssi/src/silc/core/silc-core.c.
3441 * Added support to Irssi SILC client of asynchronous public key
3442 verification and passphrase inquiry. Affected file is
3443 irssi/src/silc/core/silc-core.c.
3445 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Do not say "You have left channel %s" in client library.
3448 Moved it to the application. Affected files are
3449 lib/silcclient/command.c and silc/client_ops.c.
3451 * Fixed silc_client_get_clients. Command context was not
3452 duplicated and was freed memory in the callback. Affected
3453 file lib/silcclient/idlist.c.
3455 * Do not say "you are now talking..." on JOIN command in the
3456 client library. The appliation must handle it.
3458 * Do not say ".. changed topic to" in command reply in the
3459 client libary. The application must handle it.
3461 * Fixed TOPIC command sending in the client library.
3463 * Fixed a memory leak in silc_client_command_free in the file
3464 lib/silcclient/command.c.
3466 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Imported a modified version of Irssi client to the source tree.
3469 The Irssi will be used to create a new client called
3470 Irssi SILC. Imported to irssi/.
3472 Added silc_core_init_finish function to the Irssi. Affected
3473 file irssi/configure.in.
3475 A lot changes in the Makefile.ams around the irssi tree.
3477 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Do not rehash if the new size is same as the old size of the
3480 hash table, in the silc_hash_table_rehash*. The affected file
3481 lib/silcutil/silchashtable.c.
3483 * Replaced hash_table_del_by_context calls from the server
3484 (when channel->user_list and client->channels) to the
3485 hash_table_del as it is sufficient and faster.
3487 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Added silc_hash_table_list, silc_hash_table_get and the
3490 SilcHashTableList structure to provide an alternative way to
3491 traverse the hash table. The affected files are
3492 lib/silcutil/silchashtable.[ch].
3494 * Changed the server's idlist routines to use the hash table
3495 routines to optimize the code.
3497 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Replaced the client entry's `channel' list and channel entry's
3500 `user_list' list to hash tables for optimized lookup. Changed
3501 the code to use the hash table interface around the code.
3502 Affected file lib/silcd/idlist.[ch].
3504 * Added `auto_rehash' boolean argument to the function
3505 silc_hash_table_alloc to indicate whether the hash table should
3506 auto-rehash when it thinks is appropriate time. It will
3507 increase the hash table size if the there is twice as much
3508 entries in the table than the size of the table, and will
3509 decrease the size if there are twice as less entries than
3510 the size of the table.
3512 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3516 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * silc_idcache_purge_by_context deletes the entry now by context
3519 as it is supposed to do. Affected file lib/silccore/idcache.c.
3521 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3522 client is not anymore valid (WHOWAS givens the info) and not
3523 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3525 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Removed the `data' and `data_len' arguments from the ID Cache
3528 interfaces and added `name' argument. ID Cache does not handle
3529 anymore the binary data only a names associated with given ID.
3531 * When hashing a Client ID with silc_hash_id the entire ID is
3532 not hashed anymore, instead only the hash of the Client ID is
3533 hashed. This way we can access the Client ID from the cache
3534 with Client ID but with the hash of the ID (which is a hash of
3535 the nickname) as well without any difference in performance.
3537 Added also silc_idcache_find_by_id_one_ext to do one on one
3538 searching when we have the actual ID. Added also function
3539 silc_hash_client_id_compare. The affected files are
3540 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3542 * When hashing the name associated with a ID it is always done
3543 in lowercase. This way we can access the cache without worrying
3544 about case-sensitivity, even though, for example nicknames are
3547 * Fixed a bug in server with channel message sending. It put
3548 wrong ID type as destination ID. The affected file
3549 silcd/packet_send.c.
3551 * silc_idcache_del_by_context now deletes from all hash tables
3552 by context. Affected file lib/silccore/idcache.c.
3554 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Changed the client library to use the new ID Cache interface.
3557 Changes around the source tree.
3559 * Added silc_hash_table_rehash_ext to rehash with specific
3560 hash function. Affected file lib/silcutil/silchashtable.[ch].
3562 * Added silc_hash_string_compare to compare two strings in the
3563 hash table. Affected file lib/silcutil/silcutil.[ch].
3565 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Added new function silc_idcache_del_by_context into the
3568 lib/silccore/idcache.[ch].
3570 * Changed the server's ID list routines to use the new ID Cache
3571 interface. Changes around the source tree.
3573 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Added silc_hash_table_del[_by_context]_ext functions in to the
3576 lib/silcutil/silchashtable.[ch].
3578 Removed silc_hash_table_find_all* routines and added new
3579 silc_hash_table_find_foreach to replace them.
3581 Added silc_hash_table_replace_ext function as extended
3582 replacing function. Separated the simple hash table interface
3583 from the extended hash table interface in the file
3584 lib/silcutil/silchashtable.h.
3586 * Fixed minor bugs and changed it to use some of the new
3587 hash table functions in lib/silccore/idcache.c
3589 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Added new function silc_hash_table_find_all to return all keys
3592 in the hash table by the specified key. As the hash table is
3593 collision resistant it also makes it possible to have several
3594 duplicate keys in the hash table. This function may be used to
3595 find all of the keys from the hash.
3597 Added user_context arguments to the SilcHashFunction,
3598 SilcHashCompare and SilcHashDestructor to deliver user specified
3601 Added new fuctions silc_hash_table_find[_all]_ext to do
3602 extended lookup with specified hash and compare functions and
3603 specified user contexts.
3605 Added new function silc_hash_table_add_ext to add the key
3606 with specified hash function and user context.
3608 Added new function silc_hash_table_foreach to traverse all
3609 entrys in the hash table. Added SilcHashForeach callback
3612 Added new function silc_hash_table_del_by_context to delete
3613 the entry only if the context associated with the key matches.
3615 Affected files are lib/silcutil/silchashtable.[ch].
3617 * Removed silc_hash_[server/client/channel]_id and added just
3618 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3619 silc_hash_id_compare to compare two ID's using as the hash table
3620 comparison function. Added also silc_hash_data to hash
3621 binary data and silc_hash_data_compare to compare it.
3623 * Removed silc_idlist_find_client_by_hash as it is not needed
3624 anymore. Affected file silcd/idlist.[ch].
3626 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3627 to use internally the SilcHashTable. The new ID Cache is a lot
3628 faster than the old one. Some of the ID Cache interface was also
3629 rewritten and obsolete and stupid functions were removed.
3631 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added entry_count field to the SilcHashTable to keep the number
3634 of the entries in the table. Implemented the function
3635 silc_hash_table_rehash. Added new function
3636 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3638 Fixed a minor bug in silc_hash_table_free.
3640 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3641 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3642 into the lib/silcutil/silcutil.[ch].
3644 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Implemented a collision resistant hash table into the
3647 lib/silcutil/silchashtable[ch]. See the header and the source
3648 for the SilcHashTable API.
3650 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Merged dotconf version 1.0.2 into lib/dotconf.
3654 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Do not compile anything in lib/silcsim/* if the SIM support
3657 is not enabled. The tree should now compile without problems
3660 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Compiled the SILC under cygwin. Compiled and tested briefly
3663 without problems. More tests needed. The SIMs didn't compile
3666 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3668 * Fixed possible crash in silc_get_username in the
3669 lib/silcutil/silcutil.c.
3671 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Fixed a va_arg in silc/client_ops.c.
3675 * Oops, RC5 routines were named AES and caused some problems
3676 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3678 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added new SilcIDIP structure into the lib/silccore/id.h and
3681 replaced the old `ip' fields from all SILC ID's to that type.
3682 This is a step towards IPv6 support.
3684 The silc_id_get_len takes now the ID as an extra argument.
3685 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3686 both IPv4 and IPv6 based ID's.
3688 The affected files are lib/silccore/id.[ch] and other files
3689 around the tree using these routines.
3691 * Removed the ID length arguments in server from various
3692 silc_server_send_notify_* routines -> they are not needed
3695 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Fixed memory leak in silc_encode_pem_file in the file
3698 lib/silcutil/silcutil.c.
3700 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Check minor version as well in the SKE. Affected files are
3703 silcd/protocol.c and lib/silcclient/protocol.c.
3705 * Added --identifier option to the server so that an identifier
3706 can be when creating the public key for the server. Affected
3707 file is silcd/silcd.c.
3709 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3710 lib/silccrypt/silcpkcs.c.
3712 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Register default ciphers and stuff when using -C option with
3715 the server. Affected file sildc/silcd.c.
3717 * Put back the servers public key filename format, it is better
3718 than the new one. For now, the client keys are saved with the
3719 new filename format. The affected file silc/client_ops.c.
3721 * Implemented the Cipher API for the rest of the ciphers that
3722 did not implement it or implemented it the wrong way.
3724 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Register default ciphers and stuff when using the -S option
3727 in the client. Affected file silc/silc.c. Same also when
3728 creating new key pair with -C option.
3730 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Fixed the silc_verify_public_key client operation function to
3733 save the public keys differently. The fingerprint is now
3734 used as filename and not the hostname. This way also the
3735 client keys are saved uniquely and not with hostnames. The
3736 affected file is silc/client_ops.c.
3738 * Trimmed the silc_hash_fingerprint function to remove extra
3739 whitespaces from the end of the fingerprint. The affected
3740 file is lib/silccrypt/silchash.c.
3744 * Added silc_cipher_register_default function to register all
3745 default ciphers. It can be used when configuration files
3746 does not exist and the application does not want any specific
3747 ciphers in any specific order.
3749 The SilcDList is now used as silc_cipher_list dynamically
3750 allocated cipher list. Removed the static list all together
3751 and now all ciphers must be allocated to the dynamic list.
3752 The silc_cipher_alloc routine was changed to check only the
3755 All silc_cipher_* routines that used to return int returns
3758 The affected files lib/silccrypt/silccrypt.[ch].
3760 * The same thing was done to silc_hash_* as for silc_cipher_*
3761 routines. Affected files lib/silccrypt/silchash.[ch].
3763 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3764 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3765 Added also silc_pkcs_[un]register[_default] functions.
3766 Removed the data_context from the PKCS API.
3768 * Added silc_hmac_register_default function to register default
3769 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3770 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3771 to unregister all hmacs at once.
3773 * Register the default ciphers, hash functions, PKCSs and HMACs
3774 if client's configuration file does not exist. The affected
3777 * The client did not load the hash functions from the SIM
3778 modules at all. Added support for this. Affected file is
3779 silc/clientconfig.c.
3781 * When decoding public key with silc_pkcs_public_key_decode, check
3782 the supported algorithm only if PKCS are registered. Affected
3783 file lib/silccrypt/silcpkcs.c. The same was done with the
3784 silc_pkcs_private_key_decode.
3786 * Fixed the SILC List routines to keep the list always in order.
3787 It used to change the list's order when traversing the list but
3788 not it preserves the order. Affected file lib/trq/silclist.h.
3790 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Added the client library to use the SilcSocketConnection's
3793 reference counter (by silc_socket_dup) to prevent the bug that
3794 the socket object may be freed underneath async operation.
3796 * The name resolv library checking fixes in the configure.in.pre.
3799 * Created new version of the protocol drafts for future
3800 development. The -03 drafts are the ones that will be changed
3801 in the trunk now and the -02 will remain as they are.
3803 * Send list of CUMODE notifys to the router when announcing
3804 the channel users to the router. Affected file silcd/server.c.
3805 If the router receiving channel founder CUMODE for a channel
3806 that already has channel founder it will send CUMODE notify
3807 to the sender to remove the channel founder rights from the
3808 announced client. Affected file silcd/packet_receive.c.
3810 * The CUMODE notify may now use Server ID as well as the entity
3811 who changes the mode. Updated protocool specs.
3813 * Updated INSTALL and README files.
3815 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * New web pages in the http://silc.pspt.fi. The pages was
3822 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Implemented the [DenyConnectin] config section in the server.
3825 Added silc_server_config_denied_conn to check whether incoming
3826 connection is denied. Affected file silcd/serverconfig.[ch].
3828 * Do not check the ports when checking the incoming configuration
3829 data if the port is 0, meaning any. Affected file is
3830 silcd/serverconfig.c.
3832 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Fixed buffer overflow in silc_string_compare in the file
3835 lib/silcutil/silcutil.c.
3837 * Fixed double free in silc_server_command_leave in the file
3840 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Fixed the version checking in the server. Affected file is
3845 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed the configuration data fetching when accepting new
3848 connections in the server. Affected file silcd/server.c.
3850 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added `sender_entry' argument to the function
3853 silc_server_packet_relay_to_channel so that we can check
3854 whether some destination actually belongs to the same route
3855 the sender belongs (ie, we must not resend the packet to the
3856 sender). Affected file silcd/packet_send.[ch].
3858 * Added `servername' field to the SilcClientEntry in the server
3859 to hold the name of the server where client is from. Affected
3860 file is silcd/idlist.h.
3862 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Moved the channel message encrypting in the router betwen
3865 router connections from silc_server_channel_message to the
3866 silc_server_packet_relay_to_channel since we want to check
3867 whether we have anybody channel before encrypting anything.
3868 Affected files silcd/packet_[receive/send].c.
3870 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Fixed the [AdminConnection] server config section to support
3873 multiple entries. Affected file silcd/serverconfig.c.
3875 * Added support into the server to check the validity of the
3876 incoming connection before executing any KE or authentication
3879 * The connection configuration is now saved to the KE and
3880 connection auth protocol contexts and not fetched anymore in
3881 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3883 * The local hosts listenning address and port is also resolved
3884 now when starting the server. We want to have the socket object
3885 to include the real address and port for the listener. Added
3886 new function silc_net_check_local_by_sock into the files
3887 lib/silcutil/silcnet.[ch].
3889 * Fixed a broadcast bug in server -> do not broadcast if we
3892 * Fixed a routing bug. Do not route broadcast packets ever.
3893 Broadcast packets must be processed always and not routed since
3894 they may be destined to some other host than yourself and thus
3895 would get routed without no good reason. Affected file is
3898 * Added function silc_server_config_is_primary_route to check
3899 whether primary router connection has been configured (a router
3900 configuration that we are initiating). If there is not, we
3901 will assume that there is only two routers in the SILC network
3902 and we will use the incoming router connection as our primary
3903 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3905 * Changed the order of the broadcasting. Broadcast _after_ the
3906 packet has been processed not before. Affected file is
3909 * Fixed a [ClientConnection] parsing bug. The port was never
3910 parsed correctly thus resulting to port 0. Affected file
3911 silcd/serverconfig.c.
3913 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3914 argument and did not set the broadcast packet flag. Affected
3915 file silcd/packet_send.c. Fixed same bug in the function
3916 silc_server_send_notify as well.
3918 * If we receive NEW_ID packet for our own ID in the server, ignore
3921 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Removed the nickname from the Private Message Payload.
3926 Updated the code and the protocol specs.
3928 * Updated protocol specs for submitting to the IETF.
3930 * Tweaked the Random Number Generator a bit. Affected file
3931 lib/silccrypt/silcrng.c. Exported a new function
3932 silc_rng_[global]_add_noise which can be used to add more
3935 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Do not parse packets with different timeout when protocol
3938 is active -> may cause problem with rekey. Affected file
3941 * When server receives signoff notify it must not create
3942 new channel key if the client is on any channels since the
3943 sender of the signoff notify will create it.
3945 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Added printing of error messages during SKE protocol from the
3948 failure packet sent by server during SKE. Affected file
3951 * Removed the client's failure_callback handling with timeout
3952 and handle it immediately when received.
3954 * The SKE library returned wrong type in SUCCESS and FAILURE
3955 packets. They must be 32 bit MSB not 16 bit MSB.
3957 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Ok, rewrote the logic of the re-key and now it seems to work.
3960 I tested it on high traffic with frequent re-keys without
3961 problems. Added hmac_receive (and renamed hmac to hmac_send)
3962 in SilcClientConnection in lib/silcclient/client.h and
3963 in SilcIDListData in silcd/idlist.h. Also, removed the
3964 SilcPacketParserContext's cipher and hmac fields as they are
3965 not needed anymore and actually caused some problems when
3966 the ciphers and hmac's changed underneath the packet parser.
3968 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * If re-key protocol is active then process the incoming packets
3971 synchronously since we must assure that icoming packets encrypted
3972 with the old key is processed before the new keys is set to
3973 use. This is true other packets than for REKEY packets.
3974 Affected file silcd/server.c. The same was done to client library
3975 as well, affected file lib/silcclient/client.c.
3977 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Fixed bug in client and server to accept the force send if
3980 the packet is send from silc_[server/client]_packet_process
3981 function. Otherwise the packets are never delivered, oops.
3983 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Disable force sending of packets when REKEY protocol is active.
3986 We must assure that no packet is sent directly when rekey is
3987 performed. All packets must be sent through packet queue.
3988 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3989 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3990 function is silc_[server/client]_packet_send_real to check
3993 * Replaced the SIM paths from example config files to
3994 /usr/local/modules. Also, make install creates now
3995 /usr/local/silc/logs directory to hold all the SILC server
3998 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Made the configure.in.pre work on Solaris. Patch by salo.
4002 * Made all ciphers compatible with non-x86 machines. Defined
4003 CBC mode macros into lib/silccrypt/ciphers_def.h.
4005 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Fixed the make install.
4009 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * When MAC computation fails the silc_packet_decrypt returned 0
4012 even though it was supposed to return -1. Fixed this. The
4013 affected file is lib/silccore/silcpacket.c.
4015 * Do not replace the config files in /etc/silc (in make install)
4016 if they already exist. Affected file ./Makefile.am.
4018 * Do not send re-key packets immediately but through packet queue.
4019 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4021 * Changed silc_net_check_host_by_sock to return FALSE if the
4022 IP/DNS could not be resolved. Though, it returns the IP address
4023 now even if it could not resolve it (but returns also FALSE).
4024 Affected file lib/silcutil/silcnet.[ch].
4026 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Added silc_pkcs_decode_identifier to decode the public key's
4029 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4030 Added also silc_pkcs_free_identifier. Added also new context
4031 SilcPublicKeyIdentifier.
4033 * Added -S option to the silc client. It is used to dump the
4034 contents of the specified public key file.
4036 * Changed the PKCS api to return the public key length when
4037 setting the public key.
4039 * Fixed a fatal bug in the public and private key file loading.
4040 Affected file lib/silccrypt/silcpkcs.c.
4042 * Execute the packet parsing for client with zero (0) timeout
4043 if the protocol is active. Affected file silcd/server.c.
4045 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Made the key generation options to the silcd program. Added
4048 -C option, equivalent to client's option.
4050 * Added new [ServerKeys] config section to the server. It
4051 configures the server's public and private key.
4053 * Defined generic Public Key Payload into the protocol
4054 specification to send specific type of public keys and
4057 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4058 public key or certificate.
4060 * Implemented the GETKEY command to the server and to the
4061 client library and on user interface.
4063 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Made preliminary `make install' work.
4067 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Added SilcServerRekey context into silcd/idlist.h.
4071 * Added the PFS support as defined in the specification to the
4072 SKE protocol. Affected files lib/silcske/*.c.
4074 * Added `ske_group' field to the SilcServerRekey context to hold
4075 the number of the SKE group that is used with PFS in re-key.
4076 Affected file silcd/idlist.h.
4078 * Added PFS re-key support to the server. Affected file is
4081 * Added silc_protocol_cancel to cancel execution of the next
4082 state of the protocol. Affected file is
4083 lib/silccore/silcprotocol.[ch].
4085 * Added the re-key support with and without PFS to the client
4086 library. Re-key is performed once in an hour, by default.
4088 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4089 Added silc_client_rekey_callback and silc_client_rekey_final.
4090 Affected files are lib/silcclient/protocol.[ch] and
4091 lib/silcclient/client.[ch].
4093 * Removed the `hmac_key' and `hmac_key_len' fields from the
4094 SilcClientConnection structure; not needed. Affected file is
4095 lib/silcclient/client.h.
4099 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Do not ask whether user wants to use the negotiated private key
4102 for private messages, just use it. Affected file is
4103 silc/local_command.c.
4105 * Added `send_enc_key' and `enc_key_len' fields to the
4106 SilcIDListData structure since they are needed in the re-key
4107 phase. Affected file is silcd/idlist.[ch].
4109 * Implemented the simple re-key protocol into the server.
4110 Affected files silcd/server.c and silcd/protocol.[ch]. The
4111 re-key will be performed once in an hour, by default.
4113 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4114 Added silc_server_rekey, silc_server_rekey_callback and
4115 silc_server_rekey_final.
4117 * Removed Tunneled flag from the protocol. Updated the code
4118 and the specifications.
4120 * Adde `pfs' field to the SilcIDListData to indicate whether
4121 the PFS is to be performed in the re-key. Affected file is
4124 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4127 int64 of at least the xintXX size. If void * is less that 4
4128 bytes uint32 * will be used. Defined bool as boolean.
4130 * Changed _ALL_ unsigned long and unsigned int to uint32,
4131 unsgined short to uint16 in the source tree.
4133 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4134 not handle clients that has entry->data.registered == FALSE.
4135 They are not in the network anymore. Affected file is
4138 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Implemented the sending of the SERVER_SIGNOFF notify in the
4141 server. Affected file is silcd/server.c.
4143 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4144 Added also silc_notify_payload_encode_args into the
4145 lib/silccore/silcnotify.[ch].
4147 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4148 Affected file silcd/packet_receive.c.
4150 * Implemented the SERVER_SIGNOFF notify handling in the client
4151 library. Affected file lib/silcclient/client_notify.c. Also,
4152 implemnted the printing of the SERVER_SIGNOFF info to the
4153 application. Affected file silc/client_ops.c.
4155 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4156 if the deleting was successful. Affected file silcd/idlist.[ch].
4158 * Added support for public key authentication in the connection
4159 authentication protocol in the client library. Affected file
4160 lib/silcclient/protocol.c.
4162 * Changed the server's silc_idlist_get_clients_by_* interface
4163 to support already allocated array so that new entries may be
4164 added to pre-allocated array. Affected file silcd/idlist.[ch].
4165 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4166 and command replies.
4168 * All command reply functions in the server now calls the
4169 pending command callback even if error occured. This way the
4170 error will be delivered to the client as well. Affected files
4171 silcd/command.c and silcd/command_reply.c.
4173 * Fixed INFO command to return local server's info if no server
4174 was provided. Affected file lib/silcclient/command.c.
4176 * Removed RESTART command for good. Updated the code and the
4179 * Rewrote parts of the task system. It is a bit simpler now.
4180 Removed unsued task priorities. The affected files are
4181 lib/silcutil/silctask.[ch].
4183 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Moved the USERS printing from the library to the application.
4186 Affected files lib/silcclient/command.c and silc/client_ops.c.
4188 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added channel key re-key support. The re-key is perfomed
4193 only by the router and is done once in an hour. Added `rekey'
4194 field to the SilcChannelEntry in the server. Affected files
4195 silcd/server.c and silcd/idlist.h.
4197 * Added silc_task_unregister_by_context into the file
4198 lib/silcutil/silctask.[ch].
4200 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added SILC_UMODE_GONE mode to indicate when the client is not
4203 present in the SILC network. Added also support to the local
4204 command AWAY that will set this mode. Added support of showing
4205 "xxx is gone" in WHOIS command. The USERS command shows the
4206 gone status as well.
4208 * Fixed setting server and router operator privileges in the
4209 server's UMODE command. Affected file silcd/command.c.
4211 * Merged the SKE KE1 and KE2 payloads into one payload. The
4212 new KE payload is equivalent to the old KE2 payload.
4214 Cleaned up the SKE Start Payload parsing. It now uses the
4215 simple buffer unformatting to do the parsing. A lot faster
4218 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4219 to the SKE that is used to indicate whether both of the SKE
4220 parties should perform authentication. By default only the
4221 responder performs authentication. By setting this flag also
4222 the initiator must do authentication. By default it is unset
4223 since in normal SKE case, client to server connection, only
4224 the responder should do authentication. When doing SKE between
4225 two clients both should perform authentication. Updated the
4226 code and the protocol specs.
4228 * A little fix to IDENTIFY command in the server. Search the
4229 client first by hash not nickname. Affected file is
4232 * Fixed the silc_client_close_connection to support closing
4233 the client to client connections wihtout deleting too much
4234 data. Affected file lib/silcclient/client.c.
4236 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4237 are received if protocol used to be active but is not anymore
4238 the application would crash due to NULL pointer dereference.
4239 Affected files silcd/server.c and lib/silcclient/client.c.
4241 * Added `hash' field to the SilcClientConnection to include
4242 the hash function negotiated in the SKE protocol.
4244 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4245 to set the channel founder authentication data. A client can
4246 claim the founder rights later by providing the authentication
4247 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4248 This way the channel founder can regain the channel founder
4249 privileges even it is left the channel. This works only on
4250 local server and the client must be connected to the same
4251 server to be able to regain the founder rights. Updated the
4252 protocol specs accordingly.
4254 Added support to the CMODE command in the client to set the
4255 founder auth data. Read the README to see how to set it.
4257 Added support to the CUMODE command to claim the founder
4258 rights. Read the README to see how to do it.
4260 Added support for the founder authentication to the Channel
4261 Entry in the server. Affected file silcd/idlist.h.
4263 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4264 server's CMODE command. Affected file silcd/command.c.
4266 * Added the following new functions into lib/silccore/silcauth.[ch]:
4267 silc_auth_get_method and silc_auth_get_data.
4269 * The server now saves the remote hosts public key to the
4270 SilcIDListData pointer. Affected file silcd/protocol.c.
4272 * The normal server now does not remove the channel entry from
4273 the cache if the founder authentication data is set. It used
4274 to remove it if the founder was the last one on the channel on
4275 the server and left the channel. The auth data is saved and
4276 if the channel is re-joined later the old entry is used with
4277 the old auth data. Affected files silcd/command_reply.c and
4280 * Removed the `pkcs' field from the SilcIDListData structure
4281 in the server; it is not used. Affected file silcd/idlist.h.
4283 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Fixed packet processing on slow links. Partial packets were
4286 never re-processed because the incoming data buffer was cleared
4287 by the application. Application must not directly clear the
4288 sock->inbuf, the packet processing routines handle it. Fixed
4289 this in client library and in server.
4291 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Fixed the WHOIS and IDENTIFY send reply function to really
4294 check whether to send list or just one entry. Affected file
4297 * Cleaned up the LEAVE command's channel key distribution. The
4298 affected file silcd/command.c.
4300 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4301 can enforce the channel mode as well. In that case the ID
4302 includes the ID of the server. The code now enforces the
4303 mode change if the router have different mode than the server.
4305 * The notify client operation with CMODE_CHANGE notify can now
4306 return NULL client_entry pointer if the CMODE was not changed
4307 by client. Application must check for this.
4309 * Added <Server ID> argument to INFO command to support server
4310 info fetching by Server ID.
4312 * Added silc_server_announce_get_channel_users to get assembled
4313 packets of channel users of the specified channel. Affected
4314 file silcd/server.[ch].
4316 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4317 was freed underneath the ID Cache.
4319 * Re-announce clients when the server received CHANNEL_CHANGE
4320 notify from the router. Affected file silcd/packet_send.c.
4322 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4325 crashed since it did not handle the fact that there is no cipher
4326 called "3" and didn't check the error condition. Now fixed.
4328 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4329 flag. It can be used to send message requests.
4331 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Implemented the RESTART command in the client.
4335 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4336 notice type messages. Added notice printing to the user
4339 * The channel keys are not re-generated if the channel's mode
4340 is PRIVKEY, ie private key on the channel exists. Affected
4341 files silcd/server.c and silcd/command.c.
4343 * Fixed a little bug in channel message delivery when channel
4344 private keys are set in the server. Affected file is
4345 silcd/packet_send.c.
4347 * Changed the setting on channel->on_channel = TRUE from the
4348 silc_client_save_channel_key to the JOIN command reply. The
4349 key payload is not received if the private channel key is set.
4350 Affected file lib/silcclient/command_reply.c and the
4351 lib/silcclient/client_channel.c.
4353 * When the CMODE_CHANGE notify is sent and the channel private
4354 key mode is removed the channel key must be re-generated in
4355 other cells as well. Added this support for the router in the
4356 silcd/packet_receive.c.
4358 * Added new local command NOTICE to send notice message on
4359 channel. Affected file silc/local_command.[ch].
4361 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Added new local command ME to the client. It is used to send
4364 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4365 some action. Affected file silc/local_command.[ch].
4367 * Changed channel_message and private_message client operations
4368 to deliver the message flags to the application. Added also
4369 the `flags' arguments to the silc_client_send_channel_message
4370 and silc_client_send_private_message functions. Affected file
4373 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Redefined the Private Message Payload to support private message
4376 keys and to support the new private message flags. Updated
4377 the protocol specs. Flags makes it possible to have for example
4378 CTCP style messages.
4380 * Added new type SilcPrivateMessagePayload and defined an API
4381 for it in the lib/silcclient/silcprivate.[ch].
4383 * Tested private message private keys successfully. Tested the
4384 private message key set, unset and list commands with the new
4387 * Redefined the Channel Message Payload to include the channel
4388 message flags (equal with private message flags) to support
4389 for example CTCP style messages.
4391 * Defined some of the message (for channel and private message)
4392 flags. Updated the protocol specs and added the flags to the
4393 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4395 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added SilcKeyAgreementStatus type to the key agreement routines
4398 to indicate the current status and error if one occured.
4399 The status types are defined in the lib/silcclient/silcapi.h.
4401 * Added new local command KEY that is used to set and unset private
4402 keys for channels, set and unset private keys for private messages
4403 with remote clients and to send key agreement requests and
4404 negotiate the key agreement protocol with remote client. The
4405 key agreement is supported only to negotiate private message keys,
4406 it currently cannot be used to negotiate private keys for channels,
4407 as it is not convenient for that purpose.
4409 * Fixed a minor pending callback setting bug in the function
4410 silc_client_get_client_by_id_resolve, now the function works.
4411 Affected file lib/silcclient/idlist.c.
4413 * Added function silc_net_get_local_port to get local bound
4414 port by socket. Added to lib/silcutil/silcnet.[ch].
4416 * Added `sockets' and `sockets_count' fields to the SilcClient
4417 object. They hold the sockets of the listenning sockets in
4418 the client. Listenning sockets may be for example the key
4419 agreement server. Affected file lib/silcclient/client.[ch].
4420 Added functions the silc_client_add_socket and the
4421 silc_client_del_socket. They are exported to the application
4424 * Added ~./silc/clientkeys to support other client's public keys.
4426 * Renamed verify_server_key client operation to verify_public_key
4427 and added one argument to indicate the type of the connection
4428 (server, client etc.).
4430 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Added silc_server_connection_auth_request to handle the
4433 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4434 silcd/packet_receive.[ch].
4436 * Added silc_server_send_connection_auth_request into the
4437 silcd/packet_send.c to send the connection auth request packet.
4439 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4442 * Fixed the public key authentication in responder side in the
4443 server. The `auth_data' pointer includes the SilcPublicKey
4444 not the path to the public key. Affected file silcd/protocol.c.
4446 * Implemented the public key authentication in the initiator side
4447 in the server. Affected file silcd/protocol.c.
4449 * Removed the [RedirectClient] config section from the server
4450 configuration. Is not needed and I don't want to implement it.
4452 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Cleaned up the CMODE command in the server. It now works
4455 correctly and supports all the modes defined in the protocol.
4456 Affected file is silcd/command.c.
4458 * Added `hmac_name' field to the SilcChannelEntry in the server
4459 to hold the default HMAC of the channel. It can be set when
4460 creating the channel (with JOIN command). Affected files
4463 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4464 type to indicate the change of the current cipher and hmac
4465 on the channel. Client can safely ignore the <cipher> argument
4466 (if it chooses to do so) since the CHANNEL_KEY packet will
4467 force the channel key change anyway. The <hmac> argument is
4468 important since the client is responsible of setting the new
4469 HMAC and the hmac key into use.
4471 * Fixed the CMODE command in the client library as well.
4473 * Tested CMODE command in router environment successfully.
4475 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Show the version of the remote client (or server) when connecting
4478 to the server. It is logged to the log file. Affected file
4479 is silcd/protocol.c.
4481 * Fixed the KILLED notify handling in the client library. The
4482 client must be removed from all channels when receiving the
4485 Also, do not remove the client entry when giving the KILL
4486 command but when the KILLED notify is received.
4488 * Removed silc_idlist_find_client_by_nickname from the server.
4489 Not needed anymore. Affected files silcd/idlist.[ch].
4491 * Implemented the CHANNEL_CHANGE notify type handling to the
4492 server. Affected file silcd/server.c.
4496 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Added silc_server_send_notify_invite to send the INVITE
4499 notify between routers.
4501 * Implemented the INVITE command correctly to the server.
4503 * Implemented the INVITE notify type handling in the server.
4505 * Implemented the INVITE command to the client library and on the
4508 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added function silc_server_get_client_resolve to find the
4511 client entry by ID from all ID lists and then resolve it
4512 (using WHOIS) if it cannot be found. Affected file is
4515 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Implemented the BAN command to the client library.
4519 * The JOIN command in the server now checks the invite list
4522 * Changed the silc_command_reply_payload_encode_va and the
4523 silc_command_payload_encode_va to support that if argument is
4524 NULL it ignores and checks the next argument. Affected file
4525 lib/silccore/silccommand.c.
4527 * Added silc_server_send_notify_ban to send the BAN notify
4528 type between routers.
4530 * Chaned the silc_notify_payload_encode to support that if
4531 argument is NULL it ignores and checks the next argument.
4532 Affected file lib/silccore/silcnotify.c.
4534 * Tested ban lists in router environment successfully.
4536 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Implemented BAN command to the server, in silcd/command.[ch].
4540 * Removed the BAN and INVITE_LIST modes from the CMODE command
4543 * Added function silc_string_match to regex match two strings.
4544 Affected files lib/silcutil/silcutil.[ch].
4546 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Redefined parts of the SilcChannelEntry in the server to support
4549 the new ban and invite lists.
4551 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Redefined the INVITE command. The same command can be used to
4554 invite individuals to the channel but also to manage the invite
4555 list of the channel (to add to and remove from the invite list).
4556 Updated the protocol specs.
4558 * Added new command SILC_COMMAND_BAN that can be used to manage
4559 the ban list of the channel. Updated the protocol specs.
4561 * Removed the channel modes: the SILC_CMODE_BAN and the
4562 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4563 in the CMODE command. The equivalent features are now available
4564 using INVITE and BAN commands. Updated the protocol specs.
4566 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4567 in the network about change in the current ban list. The notify
4568 type is not used by the client.
4570 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4571 support the invite lists.
4573 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added new function silc_string_regexify that converts string
4576 including wildcard characters into regex string that can
4577 be used by the GNU regex library. Added into the file
4578 lib/silcutil/silcutil.[ch].
4580 Added silc_string_regex_combine to combine to regex strings
4581 into one so that they can be used as one regex string by
4582 the GNU regex library. Added into the file
4583 lib/silcutil/silcutil.[ch].
4585 Added silc_string_regex_match to match two strings. It returns
4586 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4588 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Imported GNU regex to the soruce tree into lib/contrib.
4591 Fixed some compiler warning from the regex.c.
4593 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Fixed MOTD command in the server to work in router environment.
4597 * Fixed the MOTD command in the client library to support
4598 the server argument in the command.
4600 * Added `nickname_len' argument to the silc_idlist_add_client
4601 in the server, as the `nickname' argument may be binary data
4604 * Added silc_idlist_get_channels to return all channels from
4607 * Implemented LIST command to the server. Affected file is
4610 * Implemented the LIST command to the client library and on the
4613 * Added [<user count>] argument to the LIST command reply.
4614 With private channels the user count is not shown.
4616 * Updated TODO and README.
4618 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * The client entry's data.registered must be TRUE even with
4621 global client entry on global client list. The data.registered
4622 is used to check whether the client is anymore in the network,
4623 for example with WHOWAS command so it must be valid.
4625 * Fixed the WHOWAS command in the server. It now actually works
4626 in router environment. Added function into silcd/command_reply.c
4627 silc_server_command_reply_whowas_save.
4629 * Added silc_idlist_purge function to the silcd/idlist.c
4630 to periodically purge the ID Cache.
4632 * Fixed INFO command in the server. It works now in router
4633 environment. Added <server name> argument to the INFO command
4634 reply. Updated the protocol specs.
4636 * Fixed minor bug in silc_idcache_purge to not purge if the
4637 expire value is zero.
4639 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4640 they were buggy because of the WHOWAS information.
4642 * Fixed local command MSG to handle the async resolving of
4643 the remote client properly. It used to fail the first MSG.
4644 Affected file silc/local_command.c.
4646 * Added `data_len' field to SilcIDCache context.
4648 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Update TODO. Todo in commands in the server.
4652 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4655 used by routers as broadcast packet to inform other routers
4656 about the changed user mode.
4658 Implemented the notify handling in the server. Affected file is
4659 silcd/packet_receive.c. Added the function
4660 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4662 * Added new generic Channel Payload and deprecated the New Channel
4663 Payload. The New Channel Payload is now the generic Channel
4666 * Added new argument `mode' to the silc_server_send_new_channel
4667 as it is required in the Channel Payload now.
4669 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4670 and created a new and real SilChannelPayload to represent the
4671 new generic Channel Payload. Implemented the encode/decode
4672 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4674 * Added silc_server_get_client_channel_list to return the list
4675 of channels the client has joined for WHOIS command reply.
4676 Affected file silcd/server.[ch].
4678 * Implemented the channel list sending in the WHOIS command reply
4679 in server and in the client.
4681 Implemented the channel list displaying on the user interface
4682 as well. Affected file silc/client_ops.c.
4684 * Added silc_channel_payload_parse_list to parse list of Channel
4685 Payloads. It returns SilcDList list of SilcChannelPayloads.
4686 Client for example can use this function to parse the list of
4687 channels it receives in the WHOIS command reply. The caller
4688 must free the list by calling silc_channel_payload_list_free.
4689 Affected files lib/silccore/silcchannel.[ch].
4691 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added one new argument <user mode> to the WHOIS command reply
4694 to return the mode of the user in SILC. Updated the protocol
4697 Implemented it to the server and client.
4699 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Fixed the mode printing on the user interface on joining.
4702 Affected file silc/client_ops.c.
4704 * Implemented the UMODE command and user modes in general to the
4705 client library and to the user interface.
4707 * Implemented the UMODE command to the server.
4709 * The server now sends UNKNOWN_COMMAND error status if client sends
4710 unknown command. Affected file silcd/command.c.
4712 * All server commands now handle the command identifier the right
4713 way when sending the command reply to the client. The client can
4714 use to identify the command replies with the identifier.
4716 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Added silc_server_get_client_route to resolve the route to
4719 the client indicated by the client ID. Affected file is
4722 * Added silc_server_relay_packet as general function to relay
4723 packet to arbitrary destination. This deprecates functions
4724 like _send_private_message_key, _relay_notify etc. Affected
4725 file is silcd/packet_send.[ch].
4727 Removed silc_server_send_key_agreement,
4728 silc_server_send_private_message_key and
4729 silc_server_packet_relay_notify functions from the file
4730 silcd/packet_send.[ch].
4734 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4735 server. Affected file silcd/packet_receive.[ch].
4737 * Implemented the KILL command to the client. Implemented the
4738 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4739 Affected files lib/silcclient/command[_reply].c and
4740 lib/silcclient/client_notify.c. Implemented the KILL notify
4741 printing in the user inteface.
4743 * Fixed a lot silc_parse_nick memory leaks from the client
4744 library in the file lib/silcclient/command.c.
4746 * Changed the silc_server_send_notify_on_channels's `sender'
4747 argument from SilcSocketConnection to SilcClientEntry to
4748 check the sender as entry and not as connection object and not
4749 to send to the client provided as argument. The affected file
4750 is silcd/packet_send.[ch].
4752 * The notify packets that are destined directly to the client used
4753 to not to be processed by the server. Now changed that and the
4754 server processes all notify packets. After relaying the packet
4755 to the client the notify packet is processed in the server.
4757 * The silc_server_free_client_data now checks whether there is
4758 pending outgoing traffic for the client and purges the data to
4759 the network before removing the client entry.
4761 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4764 an client is killed from the SILC Network. Updated the protocol
4767 Added new function silc_server_send_notify_killed to the
4768 silcd/packet_send.[ch].
4770 * Added function silc_server_packet_relay_notify to relay notify
4771 packets that are destined directly to a client. In this case
4772 the server does not process the notify packets but merely relays
4773 it to the client. Affected file silcd/packet_send.[ch].
4775 Added also silc_server_packet_process_relay_notify to check
4776 whereto relay the notify. Affected file is
4777 silcd/packet_receive.[ch].
4779 * Implemented the KILL command to the server.
4783 * Added the backup schema desgined last fall to the protocol
4784 specs for everyone to see. The specification is in the
4785 *-spec-xx.txt draft and the packet type definitions for the
4786 backup routers is in *-pp-xx.txt draft. Thusly, added also
4787 new packet type SILC_PACKET_CELL_ROUTERS.
4789 * A big security problem in the implementation discovered. The
4790 signoff of an client did not cause new channel key generation
4791 which it of course should've done. The channel keys must be
4792 always re-generated when client leaves (or signoffs) the channel.
4793 The silc_server_remove_from_channels funtion now handles
4794 the channel key re-generation.
4796 * Added `sender' argument to the silc_server_send_notify_on_channels
4797 to not to send the client provided as argument. Affected file
4798 silcd/packet_send.[ch].
4800 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Implemented OPER and SILCOPER commands into the server and
4805 * Added silc_auth_verify and silc_auth_verify_data to verify
4806 the authentication directly from the authentication payload.
4807 It supports verifying both passphrase and public key based
4808 authentication. Affected file lib/silccore/silcauth.[ch].
4810 * Added `hash' field to the SilcIDListData structure. It is the
4811 hash negotiated in the SKE protocol. Affected file is
4814 * Slight redesigning of the SilcAuthPayload handling routines.
4815 Do not send SilcPKCS but SilcPublicKey as argument.
4817 * Implemented the public key authentication support to the
4818 serverconfig. The public key is loaded from the provided path
4819 and saved as authentication data to void * pointer. Thus,
4820 changed the unsigned char *auth_data to void *auth_data;
4822 * Fixed SHUTDOWN command to send the reply before the server
4823 is shutdown. :) Affected file silcd/command.c.
4825 * Fixed fatal bug in CONNECT command. The hostname was invalid
4826 memory and server crashed. Affected file silcd/command.c.
4828 * Fixed fatal bug in CLOSE command. The server_entry became
4829 invalid but was referenced later in the command. Affected file
4832 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Fixed fatal bug in failure packet handling. Server ignored
4835 the failure and thus crashed when it came.
4839 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4842 that the command may be executed only once in (about) 2 seconds.
4843 The old SILC_CF_LAG flag is same but allows command bursts up
4844 to five before limiting.
4846 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4847 server code. Various commands now includes the CF_LAG_STRICT
4848 flag to disallow any kind of miss-use of the command.
4850 * Fixed the silc_buffer_unformat to not to allocate any data
4851 if the length of the data is zero. It used to allocate the
4852 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4854 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Changed the format of AdminConnection configuration section
4857 in the server. Added username of the admin to the format.
4858 Affected files silcd/serverconfig.[ch].
4860 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4861 to return admin configuration data by host, username and/or
4864 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Implemented WHOWAS command to the server. Added the functions:
4868 silc_server_command_whowas_parse,
4869 silc_server_command_whowas_send_reply,
4870 silc_server_command_whowas_from_client and
4871 silc_server_command_whowas_from_server
4873 * Added <Client ID> argument to the WHOWAS command reply. Updated
4874 the protocol specs accordingly.
4876 * Implemented WHOWAS command and command_reply to the client
4879 Implemented the WHOWAS printing on the user interface.
4881 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Added new argument to the WHOWAS command reply, the real name.
4884 It is an optional argument. Updated the protocol specs.
4886 * Added SilcIDCacheDestructor callback that is registered when
4887 the SilcIDCache is allocated. The callback is called when
4888 an cache entry in the ID Cache expires, or is purged from the
4889 cache. Added into lib/silccore/idcache.[ch].
4891 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4892 to destruct the client entries when the cache entry expires.
4893 Other ID Cache's in server and in the client library ignores
4896 * If the ID Cache entry's `expire' field is zero then the entry
4897 never expires. Added boolean `expire' argument to the
4898 silc_idcache_add function in the lib/silccore/idcache.[ch].
4899 If it is TRUE the default expiry value is used.
4901 * Added silc_server_free_client_data_timeout that is registered
4902 when client disconnects. By default for 5 minutes we preserve
4903 the client entry for history - for WHOWAS command.
4905 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added support to the server to enforce that commands are not
4908 executed more than once in 2 seconds. If server receives
4909 commands from client more frequently, timeout is registered
4910 to process the commands. Affected file silcd/command.c.
4911 Added new function silc_server_command_process_timeout.
4913 * Changed NICK_NOTIFY handling in client library to check that
4914 if the client's nickname was changed, so there is no need to
4915 resolve anything from the server.
4917 * Removed error printing from the WHOIS and IDENTIFY commands.
4918 If error occurs then it is ignored silently in the client library.
4919 The application, however, may map the received error to
4920 human readable error string. The application currently maps
4921 the NO_SUCH_NICKNAME error to string.
4923 * Made the command status message public to the application. Moved
4924 them from lib/silcclient/command_reply.c to
4925 lib/silcclient/command_reply.h. The application can map the
4926 received command status to the string with the
4927 silc_client_command_status_message function.
4929 * Added check to the server to check that client's ID is same
4930 as the Source ID in the packet the client sent. They must
4933 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added dist-bzip hook to the Makefile.am to make bzip2
4936 compressed distributions.
4938 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Server now enforces the maximum length for the nickname and
4941 the channel as protocol specification dictates. 128 bytes for
4942 nickname and 256 bytes for channel name.
4944 * Moved the WHOIS printing to the application. The client libary
4945 does not print out the WHOIS information anymore, the application
4946 must do it. Renamed silc_client_command_reply_whois_print to
4947 the silc_client_command_reply_whois_save.
4949 The client's idle time is also sent to the application now, and
4950 the idle is shown on screen.
4952 * Added silc_client_command_reply_identify_save to save the
4953 received IDENTIFY entries.
4955 * Do not check for channel private keys in message sending and
4956 reception if the channel does not have the PRIVKEY mode set.
4957 Affected file lib/silclient/client_channel.c.
4959 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4962 just surfaced after chaning the JOIN procedure.
4964 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Added silc_client_get_clients_by_list to get client entries
4967 from Client ID list, that is returned for example by JOIN
4968 and USERS command replies. The application should use this
4969 function for example when JOIN command reply is received to
4970 resolve the clients already on the channel (library does not
4971 do that anymore as USERS command reply is not used in the JOIN
4972 procedure anymore). Affected files lib/silcclient/silcapi.h and
4973 lib/silcclient/idlist.c.
4975 * JOIN command reply and USERS command reply returns now SilcBuffer
4976 pointers instead of unsigned char pointers when returning
4977 the client list and mode list.
4979 * Added <Client ID> argument to the JOIN command reply, mainly
4980 for the server to identify for which client the command was
4981 originally sent. Updated protocol specs accordingly.
4983 * Added SilcDlist private_key pointer to the SilcChannelEntry
4984 in the client to support the channel private keys. Affected
4985 file is lib/silcclient/idlist.h.
4987 * Added SilcChannelPrivateKey argument to the function
4988 silc_client_send_channel_message so that application can choose
4989 to use specific private ke if it wants to. If it is not provided,
4990 the normal channel key is used, unless private keys are set.
4991 In this case the first (key that was added first) is used
4992 as the encryption key.
4994 * Implemented the support for channel private key handling.
4995 Implemented the following functions:
4997 silc_client_add_channel_private_key,
4998 silc_client_del_channel_private_keys,
4999 silc_client_del_channel_private_key,
5000 silc_client_list_channel_private_keys and
5001 silc_client_free_channel_private_keys
5003 Affected file lib/silcclient/client_channel.c.
5005 * Added the support for the private keys in the channel message
5006 sending and encryption and in the message reception and
5007 decryption. Affected funtions are
5008 silc_client_send_channel_message and silc_client_channel_message.
5010 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Added SKE's key verify callback to the client library's
5013 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5015 * Removed the statement that server (or router) must send USERS
5016 command reply when joining to the channel so that the client
5017 knows who are on the channel. Instead, the client list and
5018 client's mode list is now sent in the JOIN command reply to the
5019 client who joined channel. This is better solution.
5021 * Added function silc_server_get_users_on_channel and function
5022 silc_server_save_users_on_channel to the silcd/server.[ch].
5024 * Removed function silc_server_command_send_users from the
5027 * Do not show topic on the client library anymore. The topic is
5028 sent in the command reply notify to the application and the
5029 application must show the topic now.
5031 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added client searching by nickname hash into the IDENTIFY and
5034 WHOIS commands in the server as they were clearly missing from
5035 them. Affected file is silcd/command.c.
5037 * Fixed a bug in private message receiving in the client library.
5038 The remote ID was freed and it wasn't supposed, now it is
5041 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Minor fix to the channel payload; allocate the data area, as it
5044 needs to be of specific length.
5046 * If the key agreement port is zero then the operating
5047 system will define the bound port. Affected files are
5048 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5050 * Added new function silc_channel_payload_decrypt into the file
5051 lib/silccore/silcchannel.[ch].
5053 * Moved the channel message etc, check from silc_packet_decrypt
5054 to applications. The library calls now a generic
5055 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5056 when the packet is either normal or special. This was done to
5057 allow more wide range of checking that was not allowed when
5058 the code was in library. Now applications can do virtually any
5059 checks to the packet and return to the library the decision how
5060 the packet should be processed. Affected files are
5061 lib/silccore/silcpacket.[ch].
5063 Added silc_server_packet_decrypt_check to the server and
5064 silc_client_packet_decrypt_check to the client library.
5066 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5067 to send with specified source and destination information.
5069 * Channel message delivery between routers was broken after the
5070 channel key distribution was fixed earlier. The channel key
5071 was used be to distributed to other routers as well which is not
5072 allowed by the protocol. Now this is fixed and channel keys
5073 really are cell specific and the channel message delivery between
5074 routers comply with the protocol specification.
5076 * Fixed various commands in server to check also the global list
5077 for the channel entry and not just the local list. The affected
5078 file silcd/command.c.
5080 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Added assert()s to buffer formatting and unformatting routines
5083 to assert (if --enable-debug) when error occurs. Affected
5084 file: lib/silcutil/silcbuffmt.c.
5086 * Changed to auto-reconnect to check whether the remote host is
5087 router and register the re-connect timeout if it is. It used
5088 to check that whether we are normal server, but router must do
5089 auto-reconnect with another router as well. Affected file
5092 * Removed the [<key len>] option from CMODE command as the cipher
5093 name decides the key length, nowadays. See the defined ciphers
5094 from the protocol specification.
5096 * Added [<hmac>] option to the CMODE command to define the HMAC
5097 for the channel. Added SILC_CMODE_HMAC channel mode.
5099 * Added [<hmac>] option for the JOIN command so that user can
5100 select which HMAC is used to compute the MACs of the channel
5103 * Added Hmac field to the Channel Message Payload. The integrity
5104 of plaintext channel messages are now protected by computing
5105 MAC of the message and attaching the MAC to the payload. The
5106 MAC is encrypted. Now, it is clear that this causes some
5107 overhead to the size of the packet but rationale for this is that
5108 now the receiver can verify whether the channel message decrypted
5109 correctly and also when private keys are set for the channel the
5110 receiver can decrypt the packet with several keys and check from
5111 the MAC which key decrypted the message correctly.
5113 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5114 lib/silccrypt/silccipher.[ch].
5116 * Added silc_hash_len to return the digest length into the
5117 lib/silcrypt/silchash.[ch].
5119 * Rewrote parts of Silc Channel Payload interface in the
5120 lib/silccore/silcchannel.[ch]. The encode function now also
5121 encrypts the packet and parse function decrypts it.
5123 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Fixed a minor formatting bug in the SKE's key material processing.
5126 It actually might have processed the keys wrong way resulting
5129 * Redefined the mandatory HMAC algorithms and added new algorithms.
5130 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5131 and hmac-md5 truncated to 96 bits. The mandatory is now
5132 hmac-sha1-96. Rest are optional (including the one that used
5133 to be mandatory). Rationale for this is that the truncated HMAC
5134 length is sufficient from security point of view and can actually
5135 make the attack against the HMAC harder. Also, the truncated
5136 HMAC causes less overhead to the packets. See the RFC2104 for
5139 * Added new [hmac] configuration section. The SKE used to use
5140 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5141 is of course wrong. The official names that must be proposed in
5142 the SKE are the ones defined in the protocol specification
5143 (hmac-sha1-96 for example). The user can configure any hmac
5144 using any hash function configured in the [hash] section. At
5145 least, the mandatory must be configured.
5147 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5149 * Added HMAC list to the SKE proposal list. It has now both
5150 hash algorithm list and HMAC list. This makes the protocol
5151 incompatible with previous versions. The SKE now seems to work
5152 the way it is supposed to work, for the first time actually.
5154 * Defined plain Hash algorithms to the protocol specification.
5157 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Implemented support for key agreement packets into the server.
5160 Added functions silc_server_key_agreement and
5161 silc_server_send_key_agreement. Other than these functions,
5162 server has nothing to do with this packet.
5164 * Added support for private message key packets into the server.
5165 Added functions silc_server_private_message_key and
5166 silc_server_send_private_message_key.
5170 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5171 called in the protocol's final callback instead in the END
5172 protocol state. This makes a little more sense and in the same
5173 time in client we can use the same protocol routines for normal
5174 key exchange and to key agreement packet handling as well.
5176 * Added to both client's and server's KE protocol context the
5177 SilcSKEKeyMaterial pointer to save the key material. We will
5178 bring the key material to the protocol's final callback by doing
5179 this. The final callback must free the key material.
5181 * Added SKE's packet_send callback into client's KE protocol
5182 context so that the caller can choose what packet sending function
5183 is used. This way we can use different packet sending when
5184 doing normal SKE when doing key agreement packet handling (in
5185 the key agreement packet handling we do not want to encrypt
5188 * Implemented the responder side of the key agreement routines
5189 in the client. The client can now bind to specified port and
5190 accept incoming key negotiation. The key material is passed
5191 to the application after the protocol is over.
5193 * Implemented the processing of incoming Key Agreement packet
5194 in the client. Added function silc_client_key_agreement to
5197 * Implemented the intiator side of the key agreement routines
5198 in the client. The client can now initiate key agreement with
5199 another remote client. The key material is passed to the
5200 application after the protocol is over.
5202 * Created client_keyagr.c to include all the key agreement
5205 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5206 SILC_TASK_CALLBACK except that it is not static.
5208 * Created client_notify.c and moved the Notify packet handling
5209 from the client.[ch] into that file.
5211 * Created client_prvmsg.c and moved all private message and
5212 private message key routines from the client.[ch] into that file.
5214 * Create client_channel.c and moved all channel message and
5215 channel private key routines from the client.[ch] into that file.
5217 * Changed silc_client_get_client_by_id_resolve to resolve with
5218 WHOIS command instead of IDENTIFY command, in the file
5219 lib/silclient/idlist.c.
5221 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Implemented the SKE's responder side to the Client library.
5225 * When FAILURE is received to the protocol do not trust it
5226 blindly. Register a timeout to wait whether the remote closes
5227 the connection as it should do it, only after that process the
5228 actual failure. This was changed to both client and server.
5230 * Added client_internal.h to include some of the structures
5231 there instead of client.h in lib/silcclient/.
5233 * Added function silc_task_unregister_by_callback to unregister
5234 timeouts by the callback function.
5236 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Some "Incomplete WHOIS info" errors has been appearing on the
5239 log files. Took away the entry->userinfo check from WHOIS
5240 reply sending. The entry->userinfo is now " " if client did not
5241 provide one. I thought this was fixed earlier but something
5242 is wrong still. Let's see if the error still appears.
5244 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Fixed a minor bug in the login when the channel key is
5247 re-generated in the server. It used to generate the key in
5248 wrong order and thus caused problems in the channel traffic.
5250 * Fixed a minor bug in channel key distsribution after
5251 KICK command. The key was not sent to the router even though
5254 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added silc_ske_process_key_material_data as generic routine
5257 to process any key material as the SILC protocol dictates. The
5258 function is used by the actual SKE library but can be used by
5259 applications as well. This relates to the private message keys
5260 and the channel private keys since they must be processed the
5261 same way the normal SILC session keys. The protocol dictates
5262 this. Affected files: lib/silcske/silcske.[ch].
5264 Added also silc_ske_free_key_material to free the
5265 SilcSKEKeyMaterial structure.
5267 * Defined silc_cipher_set_key function to set the key for
5268 cipher without using the object's method function. The affected
5269 files: lib/silccrypt/silccipher.[ch].
5271 * Implemented silc silc_client_add_private_message_key,
5272 silc_client_add_private_message_key_ske,
5273 silc_client_del_private_message_key,
5274 silc_client_list_private_message_keys and
5275 silc_client_free_private_message_keys functions in the
5278 Added functions silc_client_send_private_message_key to send
5279 the Private Message Key payload and silc_client_private_message_key
5280 to handle incoming Private Message Key payload.
5282 * Added Cipher field to the Private Message Key payload to set
5283 the cipher to be used. If ignored, the default cipher defined
5284 in the SILC protocol (aes-256-cbc) is used.
5286 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Removed lib/silcclient/ops.h file.
5290 Redefined parts of the SILC Client Library API. Created new
5291 file silcapi.h that deprecates the ops.h file and defines the
5292 published Client Library API. Defined also private message key
5293 API and channel private key API into the file.
5295 This is the file that the application must include from the
5296 SILC Client Library. Other files need not be included by
5297 the application anymore.
5299 * Added new key_agreement client operation callback and also
5300 defined the Key Agreement library API for the application.
5302 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5305 is used by clients to request key negotiation between another
5306 client in the SILC network. If the negotiation is started it
5307 is performed using the SKE protocol. The result of the
5308 negotiation, the secret key material, can be used for example
5309 as private message key.
5311 Implemented the Key Agreement payload into the files
5312 lib/silccore/silauth.[ch].
5314 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Redefined ciphers for the SILC protocol. Added some new ciphers
5317 and defined the key lengths for the algorithms. Changed the
5318 code accordingly. The default key length is now 256 bits.
5320 * Fixed SKE key distribution function silc_ske_process_key_material
5321 when the key length is more than 128 bits. The default key
5322 length in SILC is now 256 bits.
5324 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5325 to indicate unsupported algorithm.
5327 * Renamed rijndael.c to aes.c and all functions as well.
5329 * Fixed a long standing channel key setting bug in client library.
5330 Weird that it has never surfaced before.
5332 * Fixed bug in channel deletion. If the entire channel is removed
5333 then it must also delete the references of the channel entry
5334 from the client's channel list as the client's channel entry and
5335 the channel's client entry share same memory.
5337 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Implemented CONNECT and SHUTDOWN commands in the client.
5341 * Implemented CLOSE command to the client.
5343 * Added the function silc_idlist_find_server_by_name into the
5344 files silcd/idlist.[ch].
5346 Added the function silc_idlist_find_server_by_conn into the
5347 files silcd/idlist.[ch].
5349 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * DIE command was renamed to SHUTDOWN. Updated the both code
5354 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5355 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5357 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5360 * Added function silc_server_create_connection function to create
5361 connection to remote router. My server implementation actually
5362 does not allow router to connect to normal server (it expects
5363 that normal server always initiates the connection to the router)
5364 so the CONNECT command is only good for connecting to another
5367 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5370 or some other client was kicked from the channel.
5372 Implemented the handling of the notify type to both client
5375 Implemented silc_server_send_notify_kicked to send the KICKED
5376 notify. It is used to send it to the server's primary router.
5378 * Implemented the KICK command into server and client.
5380 * Added `query' argument to the silc_idlist_get_client function
5381 to indicate whether to query the client from server or not if
5384 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5385 to indicate that the client is not channel founder.
5389 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Removed the rng context from SilcPacketContext structure and
5392 changed that the packet routine uses the Global RNG API.
5394 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added support for quit message that client can "leave" on the
5397 channel when it quits the SILC. It is ditributed inside the
5398 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5400 Added silc_server_free_client_data that will take the
5401 signoff message as argument.
5403 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5405 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Updated parts of the protocol specification to keep it up
5410 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5413 payloads in one packet.
5415 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5416 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5417 use now the new List flag.
5419 * Also deprecated the following packet types: REPLACE_ID,
5420 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5422 * Added list support for Notify packet in server.
5424 * Added silc_server_send_notify_channel_change to send the
5425 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5426 the silc_server_send_replace_id.
5428 * Added silc_server_send_notify_nick_change to send the
5429 NICK_CHANGE notify type. Deprecates the function
5430 silc_server_send_replace_id.
5432 * Added silc_server_send_notify_join to send the JOIN notify type.
5433 Deprecates the function silc_server_send_new_channel_user.
5435 * Added silc_server_send_notify_leave to send LEAVE notify type.
5436 Deprecates the function silc_server_send_remove_channel_user.
5438 * Added silc_server_send_notify_cmode and
5439 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5440 types. Deprecates the silc_server_send_set_mode function.
5442 * Added SERVER_SIGNOFF notify type to indicate that server has
5443 quit. This means that all clients on the channel from that
5444 server will drop. This can be also used when netsplit happens.
5446 Deprecated REMOVE_ID packet type since it is not needed anymore
5449 Added silc_server_send_notify_server_signoff to send the
5450 SERVER_SIGNOFF notify type. Deprecates the function
5451 silc_server_send_remove_id.
5453 Added also silc_server_send_notify_signoff to send the
5454 SIGNOFF notify type.
5456 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5457 SILC protocol from this day on. Changed the protocol
5458 specification as well.
5460 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5461 notify type. It is used between routers to notify about
5462 topic changes on a channel.
5464 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5467 * Partly updated the protocol specification to comply with the
5468 changes now made. It is still though a bit outdated.
5470 * The JOIN notify type now takes one extra argument <Channel ID>.
5471 The packet used to be destined to the channel but now the
5472 JOIN type may be sent as list thus it is impossible to
5473 destine it to any specific channel. By adding this argument
5474 it is again possible.
5476 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added CREDITS file. The CHANGES and CREDITS file will appear
5479 in the distribution as well.
5481 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5484 types in the server's silcd/packet_receive.c.
5486 * Implemented CMODE and CUMODE to work in router environment.
5488 * Fixed minor encoding and decoding buglet from the
5489 lib/silccore/silcmode.c.
5491 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5494 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5496 * Changed all SilcConfigServer* and silc_config_server* to
5497 SilcServerConfig* and silc_server_config*, respectively.
5500 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Associated the ID (client or server ID) to the Authentication
5503 Payload to avoid any possibility of forging. Updated the
5504 protocol specification and the code accordingly.
5506 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * The RSA key length is now save to the RsaKey context in the
5509 key generation process in lib/silccrypt/rsa.c. The key length
5510 is now used to figure out the maximum size of the block allowed
5511 to be encrypted/signed.
5513 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5514 is equivalent to the silc_mp_mp2bin but does not allocate any
5517 * Changed silc_mp_mp2bin API to take length argument. If it is
5518 non-zero then the buffer is allocated that large. If zero, then
5519 the size is approximated using silc_mp_sizeinbase, which however
5522 * Created Global RNG API which is global RNG that application can
5523 initialize. After initializing, any routine anywhere in the
5524 code (including library) can use RNG without allocating a new
5525 RNG object. This was done to allow this sort of use of the
5526 RNG in code that has no chance to allocate RNG object. All
5527 applications currently allocate this and many routines in the
5528 library use this. Affected file lib/silccrypt/silcrng.[ch].
5530 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5531 it to use the Global RNG API.
5533 * Defined Authentication Payload into protocol specification that
5534 is used during SILC session to authenticate entities. It is
5535 used for example by client to authenticate itself to the server
5536 to obtain server operator privileges.
5538 Implemented this payload into the lib/silccore/silcauth.[ch].
5539 Implemented also routines for public key based authentication
5540 as the new protocol specification dictates.
5542 Moved definitions of different authentication methods from
5543 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5545 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5546 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5547 silc_pkcs_verify_with_hash functions into the file
5548 lib/silccrypt/silcpkcs.[ch].
5550 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * The client entry's userinfo pointer must be always valid.
5553 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5554 will fail since it requires the userinfo. Now, the userinfo
5555 is allocated as "" if actual userinfo does not exist. Actually,
5556 it must exist and it is totally Ok to drop client connections
5557 that does not announce the userinfo. However, we will make
5558 this workaround for now.
5560 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5561 to return the remote port by socket.
5563 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5566 SILC_SERVER_PENDING_EXEC and added an new macro
5567 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5568 data or when error occurs while processing the pending command.
5570 Added new argument `destructor' into silc_server_command_pending
5571 and to the SilcServerCommandPending object. This destructor is
5572 now called after calling the pending callback or if error occurs
5573 immediately. If error occurs the actual pending callback won't
5574 be called at all - only the destructor. The destructor may be
5575 NULL if destructor is not needed.
5577 All this applies for client library code as well. Similar
5578 changes were made there as well for the pending commands.
5580 In the client, the application must now allocate the
5581 SilcClientCommandContext with the silc_client_command_alloc
5584 * Added reference counter to the SilcServerCommandContext. Added
5585 function silc_server_command_alloc and silc_server_command_dup
5588 Same type of functions added to the client library for the same
5591 * Removed the cmd_ident from IDListData away since it is now
5592 global for all connections. It is the command identifier used
5593 in command sending and with pending commands. The affected file
5596 * Added reference counter to the SilcSocketConnection objecet to
5597 indicate the usage count of the object. The object won't be
5598 freed untill the reference counter hits zero. Currently only
5599 server uses this, and client ignores it. The client must be
5600 set to use this too later. The affected files are
5601 lib/silccore/silcsockconn.[ch]. Added also the function
5602 silc_socket_dup to increase the reference counter.
5604 This was mainly added because it is possible that the socket
5605 is removed underneath of pending command or other async
5606 operation. Now it won't be free'd and proper DISCONNECTING
5607 flags, etc. can be set to avoid sending data to connection that
5608 is not valid anymore.
5610 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5611 the connection. After that it sets SILC_SET_DISCONNECTED.
5612 It is, however, possible that the socket data is not still freed.
5613 The silc_server_packet_process now checks that data is not
5614 read or written to connection that is DISCONNECTED. The socket
5615 get's freed when the reference counter hits zero.
5617 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Changed the client operation API: channel_message operation's
5620 `sender' is now the client entry of the sender, not the nickname
5621 and the `channel' is the channel entry, not the channel name.
5623 In the private_message operation the `sender' is now also the
5624 client entry of the sender not the nickname.
5626 Affected file is lib/silcclient/ops.h and all applications
5627 using the client operations.
5629 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Moved the calling of ops->connect() from connect_to_server_final
5632 into receive_new_id functin since that is the point when the
5633 client is actually allowed to send traffic to network. The
5634 affected file is lib/silcclient/client.c.
5636 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5639 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5640 (if needs broadcasting) instead of broadcasting the packets one
5641 by one which would make a burst in the network traffic.
5643 * Added `broadcast' argument to the functions in silcd/server.[ch]
5644 silc_server_create_new_channel[_with_id] to indicate whether
5645 to send New Channel packet to primary router.
5647 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added new function into the silcd/server.[ch] files:
5650 silc_server_create_new_channel_with_id to create new channel with
5651 already existing Channel ID.
5653 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5654 lib/silccore/silcpacket.h. This packet is used t send list of
5655 Set Mode payloads inside one packet. Server uses this to set
5656 the modes for the channels and clients on those channels, that it
5657 announced to the router when it connected to it. The protocol
5658 specification has been updated accordingly.
5660 * The silc_server_new_channel did not handle the packet coming
5661 from normal server as it normally does not send that. However,
5662 when it announces its channels it does send it. Implemented
5663 the support for that.
5665 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5666 into the file lib/silccore/id.h.
5668 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Fixed memory leaks in the functions silc_idlist_del_client,
5671 silc_idlist_del_channel and silc_idlist_del_server in the file
5672 silcd/idlist.c. All of those leaked like a sieve.
5674 * Fixed some small memory leaks in the client's function
5675 silc_client_notify_by_server.
5677 * Added functions into silcd/server.c: silc_server_announce_clients,
5678 silc_server_announce_channels and silc_server_announce_server.
5679 These functions are used by normal and router server to announce
5680 to its primary router about clients, channels and servers (when
5681 router) that we own. This is done after we've connected to the
5684 These functions effectively implements the following packet types:
5685 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5686 and SILC_PACKET_NEW_ID_LIST.
5688 * Added new functions into the silcd/packet_receive.[ch]:
5689 silc_server_new_id_list, silc_server_new_channel_list and
5690 silc_server_new_channel_user_list to handle the incoming
5691 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5693 * Added support of changing Channel ID in the function
5694 silc_server_replace_id. If the server that announces a channel
5695 to the router already exists in the router (with same name but
5696 with different Channel ID), router is responsible to send
5697 Replace ID packet to the server and force the server to change
5698 the Channel ID to the one router has.
5700 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5701 client that the Channel ID has been changed by the router. The
5702 normal server sends this to the client. Client must start using
5703 the new Channel ID as the channel's ID.
5705 Implemented handling of this new type into lib/silcclient/client.c
5706 into the function silc_client_notify_by_server.
5708 * Added new function silc_idlist_replace_channel_id into the files
5709 silcd/idlist.[ch] to replace the Channel ID.
5711 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Call silc_server_command_identify_check always when processing
5714 the IDENTIFY command in silcd/command.c
5716 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5719 send keepalive packets. The packet can be sent by clients,
5720 servers and routers.
5722 Added function silc_socket_set_heartbeat into the file
5723 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5724 If not set, the heartbeat is not performed. The actual
5725 heartbeat is implemented in the low level socket connection
5726 library. However, application is responsible of actually
5729 Added silc_server_send_heartbeat to send the actual heartbeat
5730 packet into silcd/packet_send.[ch]. Server now performs
5731 keepalive with all connections.
5733 * Added silc_task_get_first function into lib/silcutil/silctask.c
5734 to return the timeout task with shortest timeout. There was a bug
5735 in task unregistration that caused problems. TODO has been
5736 updated to include that task system must be rewritten.
5738 * The client library will now resolve the client information when
5739 receiving JOIN notify from server for client that we know but
5740 have incomplete information.
5742 * Rewrote parts of silc_server_remove_from_channels and
5743 silc_server_remove_from_one_channel as they did not remove the
5744 channel in some circumstances even though they should've.
5746 * Encryption problem encountered in server:
5748 The LEAVE command used to send the Channel Key packet to the
5749 router immediately after generating it. However, the code
5750 had earlier sent Remove Channel user packet but not immediately,
5751 ie. it was put to queue. The order of packets in the router
5752 was that Channel Key packet was first and Remove Channel User
5753 packet was second, even though they were encrypted in the
5754 reverse order. For this reason, MAC check failed. Now, this
5755 is fixed by not sending the Channel Key packet immediately but
5756 putting it to queue. However, this is more fundamental problem:
5757 packets that are in queue should actually not be encrypted
5758 because packets that are sent immediately gets encrypted
5759 actually with wrong IV (and thus MAC check fails). So, packets
5760 that are in queue should be encrypted when they are sent to
5761 the wire and not when they put to the queue.
5763 However, the problem is that the current system has not been
5764 designed to work that way. Instead, the packet is encrypted
5765 as soon as possible and left to the queue. The queue is then
5766 just purged into wire. There won't be any fixes for this
5767 any time soon. So, the current semantic for packet sending
5770 o If you send packet to remote host and do not force the send
5771 (the packet will be in queue) then all subsequent packets to the
5772 same remote host must also be put to the queue. Only after the
5773 queue has been purged is it safe again to force the packet
5776 o If you send all packets immediately then it safe to send
5777 any of subsequent packets through the queue, however, after
5778 the first packet is put to queue then any subsequent packets
5779 must also be put to the queue.
5781 Follow these rules and everything works fine.
5783 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added new function silc_server_remove_clients_by_server to
5786 remove all client entries from ID list when the server connection
5787 is lost. In this case it is also important to invalidate all
5788 client entires as they hold the invalid server entry. This
5789 fixes fatal bug when server has lost connection and will reconnect
5792 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Made some sanity checks to silc_server_daemonise like to check
5795 whether the requested user and group actually exists.
5797 * Added sanity check to SKE's silc_ske_responder_finish to check
5798 that the public and private key actually is valid.
5800 * Invalidate the client's nickname when receiving Replace ID
5801 packet and the Client ID is being replaced. This means that the
5802 server will query the nickname if someone needs it (client)
5805 * Sort the ID Cache in client library when the ID Cache data
5806 has changed (needs sorting).
5808 * Do not allow for SILC client to create several connections to
5809 several servers. The client does not support windows right now
5810 and generating multiple connections causes weird behaviour.
5812 Irssi-silc client does support windows and can handle several
5813 connections without problems, see: www.irssi.org and SILC plugin.
5815 * Fixed some places where client was added to the IDList. The
5816 rule of thumb is following (in order to get everything right):
5817 If the client is directly connected local client then the
5818 `connection' argument must be set and `router' argument must be
5819 NULL to silc_idlist_add_client function. If the client is not
5820 directly connected client then the `router' argument must
5821 bet set and the `connection' argument must be NULL to the
5822 silc_idlist_add_client function.
5824 * The funtion silc_server_packet_send_local_channel actually did
5825 not check whether the client was locally connected or not. It
5826 does that now. Fixed a bug related to LEAVE command.
5828 * Fixed Remove Channel User payload parsing bug in server's
5829 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5831 * The server's silc_server_save_channel_key now checks also the
5832 global ID list for the channel as it might not be in the local
5833 list. Fixed a bug related to LEAVE command.
5835 * Is this the end of the [<unknown>] buglet that has been lurking
5836 around for a long time? A little for loop fix in server's
5837 silc_server_command_whois_parse that is used by both IDENTIFY
5838 and WHOIS command. At least, this was a clear bug and a cause
5839 of one type of [<unknown>] buglet.
5841 * WHOIS and IDENTIFY commands call the function
5842 silc_server_command_[whois/identify]_check function even if
5843 we are not router server.
5845 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Added --with-gmp configuration option. If set the GMP
5848 is always compiled in the SILC source tree. If not set then
5849 it is checked whether the system has the GMP3 installed. If
5850 it has then the GMP won't be compiled (the system's headers
5851 and library is used), if it doesn't have it then the GMP is
5852 compiled in the SILC source tree.
5854 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Changed RSA private exponent generation to what PKCS #1
5857 suggests. We try to find the smallest possible d by doing
5858 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5859 not security fix but optimization.
5861 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added new config entry [Identity] to fork the server and run
5864 it as specific user and group. A patch from Bostik.
5866 * Imported Dotconf configuration library into lib/dotconf.
5867 This will be used to create the SILC configuration files later.
5868 It will appear in the distsribution after this commit.
5870 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * A big code auditing weekend happening. Auditing code for
5873 obvious mistakes, bugs and errors. Also, removing any code
5876 Removed files for being obsolete:
5878 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5879 inline in the file lib/silcutil/silcbuffer.h)
5881 o lib/silcutil/silcbufutil.c (the header has inline versions)
5883 Changed code to fix possible error conditions:
5885 o The buffer formatting routines now check that the destination
5886 buffer really has enough space to add the data. This applies for
5887 both buffer formatting and unformatting
5888 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5889 unformatting was changed to accomodate following rules:
5890 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5891 sent to the function while XXX_*STRING will not allocate or copy
5892 the data into the buffer. Instead it sets the pointer from the
5893 buffer into the pointer sent as argument (XXX_*STRING used to
5894 require that the pointer must be allocated already). This change
5895 makes this whole thing a bit more consistent and more optimized
5896 (note that the data returned in the unformatting with XXX_*STRING
5897 must not be freed now). The routines return now -1 on error.
5899 o Tried to find all code that use buffer_format and buffer_unformat
5900 and added return value checking to prevent formatting and
5901 especially unformatting errors and possible subsequent fatal
5904 o Changed ske->x and ske->KEY to mallocated pointers in
5905 lib/silcske/silcske.h. Fixed possible data and memory leak.
5907 o Added return value checking to all *_parse* functions. Fixed
5908 many memory leaks as well.
5910 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5911 so that buffer overflows would not happen. All code now also
5912 checks the return value as it can fail.
5914 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Added reconnection support to server if the normal server looses
5917 its connection to the router (for example if router is rebooted).
5918 The server performs normal reconnection strategy implemented
5919 to the server. Affected file silcd/server.c.
5921 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Added new packet type SILC_PACKET_SET_MODE that is used to
5924 distribute the information about changed modes (for clients,
5925 channels and clients channel modes) to all routers in the
5926 network. Updated the protocol specification accordingly.
5928 Added functions into silcd/packet_send.c and
5929 silcd/packet_receive.c: silc_server_send_set_mode,
5930 silc_server_set_mode.
5932 Added new files silcmode.[ch] into lib/silccore that implements
5933 the encoding and decoding of Set Mode Payload. Added new type
5934 SilcSetModePayload. Moved the definitions of different modes
5935 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5937 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Oops, a little mistake in server's connection authentication
5940 protocol. The protocol is not ended with FAILURE but with
5941 SUCCESS if the authentication is Ok. :) Affected file is
5944 * Implemented NICK_CHANGE notify handling in server in the file
5945 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5946 the local clients on the channel. After the changing nickname
5947 in router environment snhould work and the [<unknown>] nickname
5948 should appear no more.
5950 The silc_server_replace_id function that receives the Replace ID
5951 payload now sends the NICK_CHANGE notify type also in the file
5952 silcd/packet_receive.c
5954 * Changed WHOIS and IDENTIFY command to support the maximum amount
5955 of arguments defined in protocol specs (3328 arguments). This
5956 fixed a bug that caused problems when there were more than three
5959 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Added extra parameter, command identifier, to the
5962 silc_client_send_command so that explicit command identifier
5965 Changed that ID list routines uses specific command identifier
5966 when sending WHOIS/IDENTIFY requests to the server so that they
5967 can be identified when the reply comes back.
5969 Affected files lib/silcclient/command.[ch],
5970 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5972 * Added `sender' argument to silc_server_packet_send_to_channel
5973 to indicaet the sender who originally sent the packet to us
5974 that we are now re-sending. Ignored if NULL. Affected file
5975 silcd/packet_send.[ch].
5977 * Added some server statistics support in silcd/server_internal.h
5978 SilcServerStatistics structure and around the server code. Also
5979 send some nice statistics information when client is connecting
5982 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Fixed channel ID decoding in server's JOIN command reply in
5985 silcd/command_reply.c
5987 * Fixed braodcasting of replace ID payload to not to send it if
5988 we are standalone server in silcd/packet_receive.c.
5990 * Fixed all channel message sending routines to not to send
5991 packets to clients that has router set, since they are routed
5992 separately in the same function earlier. Affects file
5993 silcd/packet_send.c and all channel packet sending functions.
5995 * In USERS reply, res_argv[i] are not allocated, the table
5996 is allocated. Thus changed that free the table, not its
5999 * In server's whois_check and identify_check if the client is
6000 locally connected do not send any WHOIS commands - they are not
6003 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Fixed some minor bugs in client when sending WHOIS command. The
6006 arguments was in wrong order.
6008 * Removed statis function add_to_channel from server in
6009 silcd/command.c that was previously used with the joining but
6012 * Tested USERS command in router environment successfully with two
6013 routers, two servers and two clients.
6015 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Reorganized the USERS command and command reply in client library
6018 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6019 When the command is given by user we register a pending command
6020 callback that will reprocess the command after the reply has been
6021 received from the server. When reprocessing the packet we then
6022 display the information. Thus, the USERS information is displayed
6023 now in the command callback instead of in the command reply
6024 callback. The processing of the command is same as previously
6025 when server has sent the command reply in the JOINing process.
6027 * Added to USERS command in silcd/command_reply.c to join the client,
6028 we didn't use to know about, to the channel after we've created
6029 a client entry for it. Also, for clienet we did know already still
6030 check whether it is on the channel or not and add it if not.
6032 * Removed silc_server_command_join_notify as the function and its
6035 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Changed the client's pending command handling to the same as the
6038 server's pending command handling. It is also now possible to
6039 execute command reply functions from other command reply
6040 function as the function callbacks for commands and command
6041 replies are one and same. The pending commands are not static
6042 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6043 in client connection context. Thus, pending commands are server
6044 connection specific as it is convenient.
6046 Changed the function silc_client_command_pending and
6047 silc_client_command_pending_del and added new function
6048 silc_client_command_pending_check. Removed the
6049 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6052 * Added cmd_ident, current command identifier, to the client
6053 connection context in lib/silcclient/client.h to keep track on
6054 command identifiers used in command sending. Client's command reply
6055 function handling now supports the mandatory command identifiers.
6057 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6058 funtions in client to fully support pending command callbacks.
6060 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6061 as one of the arguments to the application in the command reply
6064 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6065 before first releasing SILC but came back. Now it is removed again
6066 and should come back nomore. The FORWARDED flag was used only
6067 by the JOINing procedure by forwarding the command packet to router.
6068 Now, the JOINing procedure has been changed to more generic (due
6069 to various router environment issues) and FORWARDED is not needed
6070 anymore for anything. The protocol specification is yet to be
6073 Now, removed silc_server_packet_forward from server and the flag
6074 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6076 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Renamed NAMES command to USERS command. The NAMES was named that
6079 due to historical reasons. Now it is renamed. Also, rewrote
6080 parts of the USERS command. The nickname list is not sent anymore
6081 by the server. Only Client ID and mode lists are sent in the USERS
6082 command. Changed this also to the protocol specification.
6084 The client now resolves the names and stuff after it receives
6085 the USERS list from the server when joining to the channel.
6087 * WHOIS and IDENTIFY commands has been changed to support multiple
6088 Client ID's per command. One can now search for multiple users
6089 in the network by sending only one WHOIS or IDENTIFY command.
6090 Changed the code and the protocol specifications.
6092 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6093 uses silc_server_command_whois_parse to parse the request. */
6095 * If normal server, do not parse the WHOIS and IDENTIFY requests
6096 before sending it to the router. Saves some time.
6098 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Fixed JOIN command on client library. Wrong number of arguments
6101 used to crash the client.
6103 * Added silc_server_channel_has_global function to check whether
6104 channel has global users or not.
6106 * Added silc_server_channel_has_local function to check whether channel
6107 has locally connected clients on the channel.
6109 * The silc_server_remove_from_one_channel now checks whether the
6110 channel has global users or not after given client was removed from
6111 the channel. It also checks whether the channel has local clients
6112 on the channel anymore. If it does not have then the channel entry
6113 is removed as it is not needed anymore.
6115 * The silc_server_notify now checks on JOIN notify whether the joining
6116 client is one of locally connected or global. If it is global then
6117 the channel has now global users on the channel and that is marked
6118 to the channel entry. Also, it now saves the global client to
6119 global list who is joining and JOINs it to the channel. This is
6120 for normal server, that is.
6122 Changed silc_server_send_notify_on_channel,
6123 silc_server_packet_relay_to_channel and
6124 silc_server_packet_send_to_channel check if we are normal server
6125 and client has router set (ie. global client) do not send the
6126 message to that client, as it is already routed to our router.
6128 * Implemented LEAVE notify type handling in silc_server_notify
6131 * Tested LEAVE command in router environment successfully. Tested
6132 with two routers, two servers and two clients.
6136 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6138 * Implemented SIGNOFF notify type handling in silc_server_notify
6141 * silc_server_remove_id now removes the client entry from all channels
6142 it has joined and thusly sends SIGNOFF notify type.
6144 * Rewrote the NAMES list generation in server by removing two excess
6145 loops. The lists are created now inside one loop.
6147 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * silc_server_remove_channel_user checks now also global list
6150 for channel and client.
6152 * silc_server_new_channel_user checks now both local and global
6153 list for channel and client. Fixed a bug in client id decoding.
6154 Used to decode wrong buffer.
6156 * silc_server_channel_message checks now both local and global
6157 list for channel entry.
6159 * Tested channel joining (hence JOIN) in router environment
6160 successfully. Tested with two routers, two servers and two
6163 * Tested channel message sending in router environment successfully.
6165 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added silc_server_save_channel_key into server.[ch] to save the
6168 received channel key in Channel Key payload processing. It is
6169 also used in JOIN command reply handling.
6171 Equivalent function silc_client_save_channel_key added into
6172 client.[ch] into client library.
6174 * Changed JOIN command reply to send information whether the channel
6175 was created or not (is existing already) and the channel key
6176 payload. Changed protocol specs accordingly.
6178 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6179 the request was sent by ID and not by nickname. Crashed on
6182 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6185 now correctly save the received data.
6187 * silc_server_free_sock_user_data now notifies routers in the
6188 network about entities leaving the network.
6190 At the same time implemented functions silc_server_remove_id
6191 and silc_server_send_remove_id to receive and send REMOVE_ID
6192 packets. The packet is used to notify routers in the network
6193 about leaving entities. The ID removed will become invalid in
6196 * Added function silc_idlist_del_server into server. Removes and
6197 free's server entry from ID list.
6199 * silc_server_private_message function now checks, if we are router,
6200 that the destination ID really is valid ID, naturally.
6202 * In router when NEW_ID packet is received (for new client) the
6203 hash of the Client ID is saved in the ID Cache but the
6204 client->nickname is set to NULL, instead of putting the hash
6207 IDENTIFY command now also checks that client->nickname must be
6208 valid. If it is not if will request the data from the server who
6209 owns the client. Added new function
6210 silc_server_command_identify_check.
6212 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6213 to set the command to already allocated Command Payload.
6215 * Tested private message sending in router environment with two
6216 routers, two servers and two clients. Fixed minor bugs and now
6219 * Fixed segfault from client's NAMES command. Used to crash if
6222 * Forwarded packets must not be routed even if it is not destined
6223 to the receiver. Changed server code comply with this.
6225 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added `require_reverse_mapping' boolean value to ServerParams
6228 structure. If TRUE (not default) the server will require that
6229 the connecting host has fully qualified domain name.
6231 If the reverse mapping is not required and hostname could not be
6232 found the IP address is used as hostname.
6234 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Implemented version string checking to both client and server.
6237 The check is incomplete currently due to the abnormal version
6238 strings used in development version of SILC.
6240 * Changed all command functions in server to use the new
6243 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Changed char *data to unsigned char *data in ID Cache system to
6246 support binary data as ID Cache data. Changed code to support
6247 binary data in lib/silccore/idcache.c.
6249 * Renamed silc_server_packet_relay_command_reply to
6250 silc_server_command_reply as it is normal packet receiving
6251 function. Rewrote the function to accept command replys for
6252 servers and not only for clients.
6254 * Mark remote router always as registered server if we are connecting
6255 to it. Otherwise, commands sent by the router to us are ignored.
6257 * All ID List find routines now returns the ID Cache Entry pointer
6258 as well if requested.
6260 * WHOIS command works now in router environment, tested with two
6261 routers, two servers and two clients.
6263 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6264 in router environment (as it is almost equivalent to WHOIS) but
6265 hasn't been tested thoroughly. Added new functions:
6267 silc_server_command_identify_parse
6268 silc_server_command_identify_send_reply
6269 silc_server_command_identify_from_client
6270 silc_server_command_identify_from_server
6272 * Disabled route cache adding because adding two different ID's with
6273 same IP replaces the old cache entry thus giving wrong route.
6274 The entry->router->connection is always the fastest route anyway
6275 so route cache may not be needed. Of course, new routes maybe
6276 established after receiving the ID when the entry->router->connection
6277 might not be anymore the most optimal.
6279 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Add route cache for received ID for fast routing.
6283 * Added silc_server_packet_route to route received packet on router
6284 that is not destined to us.
6286 * Renamed silc_server_get_route to silc_server_route_get.
6288 * Added id_string and id_string_len fields into SilcServer to
6289 include encoded ServerID for fast comparing without excess
6290 encoding of the ID's.
6292 * Cleaned up WHOIS command on server side. Added following static
6295 silc_server_command_whois_parse
6296 silc_server_command_whois_check
6297 silc_server_command_whois_send_reply
6298 silc_server_command_whois_from_client
6299 silc_server_command_whois_from_server
6301 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6302 arguments in command replies. All command functions should be
6303 updated to use this macro.
6305 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Minor typo fixes on command reply handling on server.
6309 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Added silc_server_command_add_to_channel internal routine to add
6312 the client to the channel after router has created the channel and
6313 sent command reply to the server.
6315 * Added generic silc_server_send_command to send any command from
6318 * Use static buffer with ID rendering instead of duplicating data.
6320 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Fixed a channel user mode bug when joining to a channel server gave
6323 everybody channel founder rights, oops.
6325 * We mark ourselves as the router of the incoming server connection
6326 if we are router ourselves. This way we can check in some packet
6327 sending functions whether it is locally connected server. For
6328 incoming router connections we put NULL.
6330 * For router sending packets locally means now always sending the
6331 packet cell wide; to local clients and local servers. For normal
6332 server sending packet locally means sending it to only local
6335 * Fixed the JOIN command to really work in router environment. If the
6336 channel is created it is always created by the router. Router is
6337 also responsible of making the initial joining to the channel,
6338 sending JOIN notify to the sending server and distributing
6339 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6340 does not exist server doesn't do anything else but forward the
6341 command to the router which performs everything.
6343 * Added silc_server_send_channel_key function to send the Channel Key
6346 * Added silc_server_create_channel_key to create new channel key. The
6347 channel key is now re-generated everytime someone joins or leaves
6348 a channel, as protocol dictates. Note: channel->key_len is the
6351 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6354 packet_receive.[ch] to separate packet sending and receiving
6355 routines. The server.[ch] now includes everything else including
6356 actual packet processing (writing and reading data) and other
6359 Renamed silc_server_private_message_send_internal to
6360 silc_server_send_private_message. The routine is still though
6361 used only to relay private messages as server does not send
6362 private messages itself.
6364 Renamed silc_server_new_channel to silc_server_create_new_channel
6365 and added new function sicl_server_new_channel that handles the
6366 incoming New Channel packet. Added also new sending function
6367 silc_server_send_new_channel to send New Channel Payload.
6369 * Added new function silc_server_notify to process incoming notify
6370 packet to the server/router. Server may then relay the notify
6371 to clients if needed.
6373 * Added new function silc_server_new_channel_user to process incoming
6374 New Channel User packet. Router will redistribute the packet and
6375 send JOIN notify to its local clients and locally connected servers
6376 if needed. Normal server will send JOIN notify to its local client
6377 on same channel when received this packet. Added also corresponding
6378 sending function silc_server_send_new_channel_user to sent the
6381 * Added boolean route argument to send_notif_to_channel and
6382 packet_send_to_channel functions to attempt to route the packet
6383 if it is TRUE and send only locally if it is FALSE.
6385 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * silc_server_replace_id now broadcasts the received replace ID
6388 packet if it is not broadcast packet already. The router must
6389 broadcast to inform other routers about changed ID.
6391 * Added backpointer to server's router into SilcServer context in
6392 silcd/server_internal.h.
6394 * Fixed silc_server_packet_broadcast to send correct broadcast
6397 * The channel key is now distributed to the local client as soon
6398 as it is received from the router (in router environment) so that
6399 no other packet may be sent for the channel until client has
6402 * silc_server_remove_channel_user now broadcasts the received
6403 Remove Channel User packet if it is not broadcast packet already.
6404 The router must broadcast to inform other routers about removed
6407 * Added users field into SilcPacketContext that is a reference count
6408 of the context. One can increase the reference count by calling
6409 silc_packet_context_dup which is now changed to just increase the
6410 reference count instead of duplicating the data. The reference
6411 count is decresed by calling silc_packet_context_free that will
6412 free the data after the reference count hits zero.
6414 For now on the packet context and everything allocated into it
6415 (including the raw packet from network) must be freed by calling
6416 the new silc_packet_context_free function. Added also new function
6417 silc_packet_context_alloc that must be used now to allocate the
6418 context. This also means that if a routine is asynchronous from
6419 silc_[client/server]_packet_parse_type the packet context must
6420 be duplicated by calling silc_packet_context_dup. Otherwise it
6421 gets free'd after silc_[client/server]_packet_parse_type returns.
6422 Also, one must remember that if packet is duplicated then its
6423 reference count must be decresed by calling the free function as
6424 many times as it was duplicated.
6426 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6427 from both client and server.
6429 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Made joining to a channel working in router environment.
6433 * Cleaned up JOIN command on server side and create function
6434 silc_server_command_join_channel internal routine to make the
6437 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Changed silc_command_pending list to SilcDList. Also, added
6440 `ident' field to SilcServerCommandPending structure to identify
6441 the reply and to call correct callback.
6443 Added silc_server_command_pending_check function to replace the
6444 corresnponding macro. The silc_command_pending list is not
6447 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6448 to set identifier to previously allocated Command Payload. It
6449 is used to set identifier for command when resending Command
6452 * Added silc_command_payload_encode_payload to encode Command
6453 Payload buffer from SilcCommandPayload structure.
6455 * Added silc_argument_payload_encode_payload to encode Argument
6456 payload buffer from SilcArgumentPayload structure.
6458 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Changed WHOIS command to support router connection on server side.
6461 The whois request is always sent to router unless the server is
6462 standalone server. After server has received the reply from the
6463 router will it send the reply to the client.
6465 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6466 broadcast received broadcast packet. The function is used only
6467 by router. The broadcast packet is always sent to the router's
6470 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6471 render given ID to printable string, for log files for example.
6473 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Made basic router to router connections working. At least they
6476 can now connect to each other but nothing really works the way
6477 they are supposed - yet.
6479 * Added new initiator token to RouterConnection configuration
6480 file in silcd/serverconfig.[ch]. It is used to tell whether we
6481 are the initiator to the remote router or whether we'll expect
6482 the other end to connect.
6484 * Moved registering of listener task to silc_server_init, hence
6485 the server starts listenning as soon as it is run, even if it
6486 does not have connections to other routers. Let's see how well
6489 * Changed default connection retry timeouts for more suitable in
6492 * Removed cipher and such arguments from silc_idlist_add_client
6493 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6494 Added new function silc_idlist_add_data to add the keys and stuff
6497 * Added SilcIDListData structure and added it to SilcClientEntry
6498 and SilcServerEntry as their first field in the structure. This
6499 way we can explicitly cast the ID entries to the SilcIDListData
6500 structure and get common data for the entries. In past, we had
6501 to first check what type of connection it is and then cast it to
6502 correct ID entry type. Now, we can directly cast the opaque
6503 pointer to the SilcIDListData (no matter what ID entry it actually
6504 is) and get the data needed.
6506 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6509 in some circumstances even if threre were timeout tasks, though not
6510 IO tasks, but tasks anyway. Now fixed.
6512 * Defined SilcServerConnection structure to hold connection specific
6513 stuff about directly connected servers and routers. The definition
6514 is currently in silcd/server_internal.h. I thought about having
6515 a bit more important role fro this struct but for now it is used
6516 only when connecting to other server (or router actually).
6518 * Added connecting retry support in server when connecting to
6519 router(s). The retry feature implement exponential backoff
6520 algorithm. Also, added SilcServerParams structure to hold default
6521 parameters for server. For now, it include these retry settings
6522 and are hard coded. After server is moded to be as Silc Server
6523 Library this structure will be more important.
6525 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Changed client librarys channel->clients table to SilcList and
6528 changed code accordingly.
6530 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Changed client's channel table to SilcList and changed code
6533 accordingly. Also changed SilcChannelClientEntry to include back-
6534 pointer to the channel so that client entry can use that structure
6535 as list as well and we have fast cross-reference to the channel.
6536 This change dramatically decreased the complexity of channel
6537 handling with client entry and vice versa (removed one extra
6538 loop when searching for channel entry from many functions).
6540 * Changed server->sim from table to SilcDList and changed code
6543 * NAMES command can now be used from user interface. It will show
6544 the user list on the channel, neatly.
6546 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6547 Code now saves realname of the user if it becomes available.
6549 * Renamed configure.in to configure.in.pre and made ./prepare
6550 script to automatically add correct version string to
6551 configure.in which it creates from configure.in.pre.
6553 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * NAMES command reply now shows users mode with the nickname when
6558 * Moved silc_client_ch[u]mode[_char] functions from
6559 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6560 place sucks, they are utility functions and should be in some
6563 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6565 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6568 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Added TRQ (efficient deque and list library) into lib/trq. This is
6573 a very good list library that is currently used in the SILC. Defined
6574 SilcList API over the library because I didn't like the API very
6575 much. See lib/trq/silclist.h for the API and examples of how to
6576 use the API. Fixed various places in the code to use the new
6577 SilcList API. The SilcList is meant for lists that has a structure
6578 already defined as a list. It is not suitable to add just some
6579 context to the list (in TRQ, the context is the list actually).
6581 So, I defined SilcDList that can be used for the purpose where
6582 predefined list structure does not exit. This can be used as
6583 such list. Now some context just can be added to the SilcDList.
6584 Currently this list is not used in the SILC just yet, though there
6585 are a lot places where this can replace dynamically allocated
6586 tables and I will fix these places, later, to use SilcDList.
6587 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6588 and use TRQ internally).
6590 Also fixed some annoying warning messages that the original TRQ
6591 code generated. Also minor changes to TRQ's Makefile.in.
6593 * Added support for querying by Client ID to both WHOIS and
6594 IDENTIFY commands into server, as required by the protocol.
6596 * Removed method function pointers from SilcBuffer structure. They
6597 weren't used to anything and just increased the context size for
6598 no good reason. This change also made silc_buffer_alloc and
6599 silc_buffer_free functions inline functions.
6601 * Disabled command flooding detection support until it's fixed so
6602 that it accepts commands in but does not execute them more than once
6605 * Added silc_net_localhost(), to return local hostname, into
6606 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6607 that must be initialized before calling silc_client_init.
6609 * Added new function: silc_server_send_notify_on_channels to send
6610 notify messages to all channels client has joined. It is assured
6611 that the message is sent only once per client.
6613 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6614 lib/silcutil/silcutil.[ch] as silc_format function. The new
6615 function is generic and is used by server as well, not only by
6616 the logging routines.
6618 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6619 the provided version string was not acceptable. Added new function:
6620 silc_ske_check_version into lib/silcske/silcske.h. The function
6621 must be implemented by the application (client or server) and it
6622 does not reside in the SKE library. The function checks the version
6623 string remote end sent.
6625 * Added back pointers (to opaque context and to SilcSocketConnection)
6626 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6628 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6629 duplicate packet context structure.
6631 * Changed `notify' client operation to send same arguments as client
6632 receives from server except for ID's. ID's are mapped to correct
6633 ID entry and that is returned. Also, if channel entry is not sent
6634 by server but the notify is for channel the channel entry is sent
6635 to application (otherwise application doesn't know that it is for
6636 channel (library gets it from packet's Destination ID)).
6638 * Added silc_client_remove_from_channels into client library to
6639 remove a client from all channels it has joined to. Used when
6640 received SIGNOFF notify from server. Added also new function
6641 silc_client_replace_from_channels to replace old ID entry with
6642 new ID entry on all channels. Used when received NICK_CHANGE
6645 * Fixed ID Cache list handling in silc_idlist_get_client in
6646 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6647 to get (or query) client by ID.
6649 * Updated TODO list.
6651 * Added connection authentication status message defined by the
6652 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6653 support for these into the code in client and server side.
6655 * Added generic function silc_client_send_command to send any command
6656 with variable argument list. Application should use this function
6657 to send commands if the command functions provided by the library
6658 does not suite for the application's user interface needs.
6660 * Added new `failure' client operation. Application is notified about
6661 received failure packet if client is executing a protocol. In this
6662 case the protocol's execution has failed.
6664 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6665 is required by the protocol.
6667 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6668 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6671 * Added status flag to SilcSKE object to indicate realtime status
6672 of the SKE protocol.
6674 * Application receives now exactly same command reply arguments as
6675 the library receives from server. However, if ID is received the
6676 corresponding ID entry is returned to the application (eg. Client
6677 ID is mapped to correct SilcClientEntry entry and that is returned).
6678 Changed command_reply client operation due to this change.
6680 * Changed all ID's in commands and in command replys as ID Payloads.
6681 Change affected both client and server side codes.
6683 All ID's sent in SILC network (with execption of ID's in SILC
6684 Packet header) are sent in ID Payload to support variable length
6687 * Server now notifies nick changes and notifies all clients on
6688 the channels about the new nickname (about the new Client ID,
6691 * Implemented CMODE command to change channel modes. Supports all
6692 channel modes defined by the protocol specs except ban and invite
6693 lists. (Also, private channel key mode is supported but support for
6694 setting private channel key in client is missing, thus, this mode
6695 has no effect on client side (except that server requires that the
6696 client uses private channel key and normal channel traffic does not
6699 Also, invite mode works per se, but INVITE command does not work
6700 yet correctly, so you can set channel as invite only channel but
6701 inviting clients to the channel does not work (it is yet to be
6702 thought what's the best way to do it).
6704 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6705 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6706 Implemented CUMODE command to change user's mode on the channel.
6707 Supports all modes defined by the protocol specs.
6709 * Added NAMES command reply to return users modes on the channel.
6711 * Removed unnecessary and slow ciphers from lib/silccrypt.
6713 * Set SO_KEEPALIVE option to connection sockets by default.
6715 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6717 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6718 redefined the Notify Payload into protocol specs.
6720 * Added silc_id_payload_parse_id to get ID directly from raw
6723 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6726 accept searching by Client ID as well.
6728 * Added support for LEAVE and SIGNOFF notify types in client library.
6730 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6731 to parse ID Payload from raw data.
6733 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Added flags parameter into silc_ske_assemble_security_properties
6736 function in lib/silcske/silcske.[ch].
6738 * Changed notify client operation to fit better for notify messages
6739 sent by server. The notify payload received from server is now
6740 passed to the application (after parsing it to SilcNotifyPayload).
6741 It is application's responsibility to retrieve the arguments
6742 from the payload and show the message the way it wants. The message
6743 sent by server is implementation specific.
6745 * Changed public keys to comply with the protocol specification.
6746 Old public keys are not supported anymore and are not compatible.
6748 * Removed nickname from Channel Payload as the latest draft removed
6749 it. The client must resolve the nickname from the NAMES command
6750 reply received when it joined the channel.
6752 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6754 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Fixed some errors in protocol specification drafts.
6758 * Created lib/silccore/silcnotify.c to implement Notify Payload
6759 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6760 generic payloads described by protocol specifications. The file
6761 includes implementations for ID Payload and Argument Payload.
6763 * Changed Command Payload implementation to use the new Argument
6764 Payload. Changed command_xxxx_payload to command_payload_xxxx
6765 to comply with SILC coding conventions.
6767 * Added suppport for Argument Payload handling in Notify Payload
6768 implementation as protocol requires it. Added the new support
6769 into server and client lib as well.
6771 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added support for multiple nicknames on same channel. [n] is
6774 added locally to the nickname if there are more than one same
6775 nicknames on the channel.
6777 * Server now sends all nicknames that matched WHOIS request.
6778 Client also shows the list received from server.
6780 * Added TOPIC command to client side. User can now set and show
6781 current topic on channel.
6783 * Added MOTD command to client and server. Also, server sends the
6784 motd when client connects to the server.
6786 * Changed version strings to comply ISO 8601.
6788 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * Fixed protocol error handling in client library. It should now
6791 cope even if the SKE fails for some reason.
6793 * Made new protocol specification drafts for submitting to IETF.
6795 * Implemented TOPIC command to server in silcd/command.c.
6797 * Added two new notify types into lib/silccore/silcnotify.h:
6798 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6799 notify nickname change and topic setting/change on a channel.
6801 * API change of command_reply operation in client library. The
6802 application gets now the status type received from server as well.
6804 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6808 * Cras fixed and optimized the packet handling even further and
6809 it should work now. Minor change to the prototype of function
6810 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6812 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Added new function into lib/silcutil/silcschedule.[ch]:
6815 silc_schedule_with_fd to select() a specified fd. The function
6816 returns after timeout expires or data arrives or goes. The
6817 function is used by packet routines to wait that all data is
6818 received from network.
6820 * Fixed data reading from network in lib/silccore/silcpacket.c.
6821 The code now assures that all data is read from the fd and then
6822 continues packet processing. This was a bug fix since the code
6823 used to drop some data in some circumstances.
6825 * Added new function into lib/silcclient/client.[ch]:
6826 silc_client_start_key_exchange to start key exchange after
6827 connection has been established to server. The code internally
6828 now uses this funtion but its main purpose was to provide it
6829 for applications that perform their own connecting. After
6830 application has created a connection it merely calls this
6831 function to start the key exchange between client and server.
6832 The library takes care of everything else after that.
6834 Updated also lib/silcclient/README to explain the usage of
6837 * Do not send to application information that connection has
6838 been established. Application gets notified it by connect
6841 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Applied cras's patch to add silc_schedule_one function. The
6844 function runs scheduler once and returns.
6846 * Fixed the scheduler after cras messed it up. The timeout
6847 handling works now as it's supposed to work.
6849 * Added into lib/silccore/ silcnotify.h to include notify
6850 message types support. Changed silc_server_send_notify*
6851 functions, in server.[ch], to support those new notify types.
6852 Added the support for the notify types into client library,
6853 as well. Added new notify client operation into ops.h in
6856 * Changed silc_server_packet_send_to_channel to send normal
6857 packets instead of just channel message packets. The function
6858 is now used to send the notify packets to channels. It is not
6859 used to send channel message packets anymore, as server never
6862 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6863 va_arg()s as it seems to require it nowadays. I guess, if SILC
6864 is compiled with older va_arg() the new code should work anyway.
6866 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Splitted core library. Core library (lib/silccore) includes
6869 now only SILC protocol specific core (and common) components.
6870 Created new utility library (lib/silcutil) that includes more
6871 generic purpose stuff. The stuff for util library was taken
6872 from the old core library. This was minor and easy split.
6874 * Created SILC Client Library (lib/silcclient) that includes
6875 implementation of the SILC client without user interface. This
6876 was major move from silc/ directory. The code has been changed
6877 so that it is transparent towards the user interface. The
6878 silc/ directory includes now the same user interface as before
6879 and it uses the new client library. Read lib/silcclient/README.
6880 Basicly, the client library performs everything else related
6881 to SILC except user interface handling. Also, configuration
6882 files are considered to be part of user interface and library
6883 does not handle them.
6885 This change also changed a lot of structures, function naming etc.
6886 Most important change was that SilcClientWindow object was
6887 renamed to SilcClientConnection in the client library. Created
6888 also new file lib/silcclient/ops.h. Also added new files
6889 silc/local_command.[ch] and silc/client_ops.[ch].
6891 All these changes were made to make it easier for user interface
6892 designers to create what ever user interface for the SILC client
6895 It is also expected that the server will be moved to lib
6896 directory as well and SILC Server Library will be created;
6897 sometimes in the future.
6899 * Removed Local commands from lib/silccore/silccommand.h as
6900 they are application specific and new client library does not
6901 handle any of those anymore.
6903 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6904 old client implementation in silc/.
6906 * Added support for callback functions in SILC_LOG_* macros.
6907 Application can now set its own callbacks that will be called
6908 instead of using the default functions that will always print
6909 the debug messages to stderr (or stdout). Also, debugging can
6910 now be disabled by setting silc_debug to FALSE and re-enabled by
6911 setting it to TRUE. Note, that logging will still work even
6912 if debugging is disabled.
6914 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6915 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6916 silc_log_reset_debug_callbacks.
6918 * To enable debugging in silc client one must give now -d
6919 option on command line.
6921 * Changed silc_schedule_init to automatically allocate task queues
6922 if they are not allocated before calling it.
6924 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added GMP 3.1 into math library.
6928 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6931 a channel in SILC network. The packet is used by servers and
6932 routers to notify other routers that user has left a channel.
6933 This little feature was missing until now. Added the feature
6934 to protocol specification as well.
6936 Added functions: silc_server_send_remove_channel_user and
6937 silc_server_remove_channel_user into server.[ch].
6939 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6940 lib/silccore/silcpacket.h. However, they are not implemented
6943 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Fixed joining to a channel and sending channel messages
6946 between server and router. The channel message sending should
6947 now work inside a cell.
6949 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6951 * Fixed the private message sending between server and router.
6952 The private message sending should now work inside a cell.
6954 * Added silc_server_replace_id into server.[ch] to replace
6955 existing ID in the SILC network.
6957 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6958 and silc_idlist_replace_server_id into idlist.[ch] in server.
6960 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Fixed the server to server connections. Server can again now
6963 connect to router. Router to router connections probably does
6966 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Added dynamic protocol registering support. Now protocols can
6969 registered and unregistered on the fly. Patch by cras.
6971 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added lib/contrib directory to hold routines that some platforms
6974 don't have but are needed by SILC.
6976 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6977 into lin/contrib to provide getopt() and getopt_long() for
6978 those who don't have it.
6980 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6982 * Added AWAY command to client. When away message is set and
6983 client receives a private message packet the client automatically
6984 replies to the sender with the away message.
6986 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6987 bug seemed to be the cause of recent problems when compiling
6990 * Added version detection support to SKE protocol specification
6991 and added the new changes to the SKE implementation as well.
6992 There were other minor changes in the SKE protocol as well.
6994 Many changes in lib/silcske/silcske.[ch] and in
6995 lib/silcske/payload.[ch].
6997 * Added ^U functionality, clear input line. Patch from cras.
6999 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Mainly small bugfixes on core library. Fixed some debugging
7002 logging and buffer overflow in silclog.c.
7004 * Updated config.sub and config.guess on the distribution tree.
7006 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Added command lagging support in server. Client may execute
7009 commands now only once in two seconds.
7011 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Optimized packet reception. MAC computation and checking is now
7014 also more optimized. A lot previously duplicated code is now
7015 used as generic by both client and server.
7017 * Fixed key pair generation in clientutil.c
7019 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * Added into lib/silccore/silcbufutil.[ch] new function;
7022 silc_buffer_realloc.
7024 * Moved generic packet sending/encryption functions to
7025 lib/silccore/silcpacket.[ch] from client and server. Some
7026 rewriting of the functions.
7028 * Moved all generic packet reception/decryption functions to
7029 lib/silccore/silcpacket.[ch] from client and server. The
7030 packet processing is now much cleaner in both client and server.
7031 These were major changes in both client and server.
7033 * Created many common functions in server to do packet sending.
7034 Previously code were duplicated a lot, this has been removed
7037 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Rewrote major parts of the ID cache system. Don't know
7040 whether it is better now or not but at least the API is more
7043 * Major rewrite on ID cache stuff on client because of the ID
7044 cache API changes. Added idlist.c to client.
7046 * Also major rewrite on ID cache stuff on server as well.
7047 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7048 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7049 in hand, instead they are all put into the ID cache system now.
7050 All server_idlist_* routines uses ID cache now instead of
7051 traversing its own lists (those lists does not exist anymore).
7052 SilcIDList though still exists. Also, SilcXXXEntry's are
7055 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Finally made the SKE implementation compliant to the protocol
7058 specification. All mp integers are now binary encoded as
7059 opposed being HEX encoded.
7061 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7064 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7065 functions: silc_[encode/decode]_pem. Also added function
7066 silc_encode_pem_file to PEM encode with newlines ('\n') for
7069 * SILC public keys are now encoded either PEM or binary. Same
7070 option is for private keys as well. By default private keys
7071 are binary encoded and public keys PEM encoded. Silly HEX
7072 encoding were removed.
7074 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7075 function to create fingerprints.
7077 * Fixed a bug in SHA1; does not change the original data anymore.
7079 * Partly implemented INFO command on client and server side.
7080 Fixed CLEAR command. Changes to SERVER command; show current
7081 server(s) when giving command without arguments. Added
7082 VERSION command to client.
7084 * Added check to server that unregistered connections cannot
7085 execute commands (unless it is specificly allowed).
7087 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Fixed screen refresh.
7091 * Fixed channel joining bug from client. On some circumstances
7092 client tried to join to a channel it had already joined.
7094 * Added public key verification process into client's protocol.c.
7095 The client now verifies the public key from user and saves
7096 it into ~./silc/serverkeys/ directory.
7098 Added into: clientutil.[ch]: silc_client_verify_server_key.
7100 * Changed SKE protocol's silc_ske_initiator_finish function
7101 to accept callback function that verifies the received public
7102 key. Removed old silc_ske_verify_public_key function.
7104 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7107 silc_pkcs_private_key[_data]_set.
7109 * Made the password and public authentication more cleaner in
7110 server's protocol.c.
7112 * Removed historic and obsolete protocol `channel_auth' from
7113 both client and server.
7115 * Removed wrong way of sending command status messages from
7116 server to client in server's command.c. The old way violated
7117 protocol specification.
7119 Changes to silccore/silccommand.[ch]: removed
7120 silc_command_encode_status_payload -> not needed anymore,
7121 changed silc_command_encode_payload_va to accept extra
7122 argument on variable argument list. The argument type must
7123 now be provided to the function. Also, added new function:
7124 silc_command_encode_reply_payload_va which is same as
7125 normal command_encode_payload_va except command status type
7126 is provided as extra argument.
7128 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7130 * Added ~./silc directory handling. The directory includes the
7131 public and private keys for the client.
7133 Added silc_client_check_silc_dir, silc_client_create_identifier
7134 and silc_client_load_keys.
7136 * Implemented SILC protocol compliant public key. Added public
7137 and private key saving to and loading from files.
7139 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7140 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7141 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7142 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7143 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7145 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7146 silc_pkcs_load_[public/private]_key.
7148 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Added silc_server_get_route (route.[ch]) to get connection
7151 data for the fastest route for given ID.
7153 * Implemented INVITE command on client and server. The command
7154 were re-defined in the SILC Protocol Specification and the
7155 implementation now complies with the specification.
7157 * Implemented PING command on client and server.
7159 * Implemented NAMES command on client and server. The server side
7160 supports currently only normal server not router server yet.
7161 Some changes to NAMES definition in SILC protocol specification.
7163 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * Implemented LEAVE command on client and server.
7167 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7168 again. This change was made to the protocol as well. Server
7169 should not violate the protocol specification anymore.
7171 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7174 was tested. SOCKS4 was not but should work anyway.
