3 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
6 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Added `user_count' to the SilcChannelEntry which now tells the
9 number of users on the channel. The user count is now saved
10 in normal server of global channels as well. Affected files
11 silcd/server.c, idlist.h, packet_receive.c and command.c.
13 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
14 include file utility functions.
16 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
17 instead of calling directly OS routines.
19 * Fixed NICK change printing in Irssi SILC Client. Fixed
20 KICKED notify printing in Irssi SILC Client. Affected file
21 irssi/src/silc/core/client_ops.c.

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

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

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

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

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

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

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

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

379 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
381 * Added lib/silcclient/client_ops_example.h as an template
382 file for application programmers to quickly start using
383 the SilcClientOperation functions in their application.
384 Updated the lib/silcclient/README as well to tell about this
385 nice file made available.
387 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
389 * Call silc_server_remove_from_channels when removing client
390 entry when NO_SUCH_CLIENT_ID was received. Affected file
391 is silcd/command_reply.c.
393 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
395 * Added server & router operator statistics updating. Affected
396 file silcd/packet_receive.c and silcd/command.c.
398 * Fixed the SERVER_SIGNOFF notify handling on normal server
399 not to save the history information for clients. Same was
400 fixed earlier in remove_clients_by_server function, but not
401 here. Affected file silcd/packet_receive.c.
403 * Raised the default connection-retry count from 4 to 7 in
404 server. Affected file silcd/server.h.
406 * Cancel any possible reconnect timeouts when we start the
407 key exchange. Affected file silcd/server.c.
409 * Do not reconnect on connection failure when SCONNECT was
410 given. Affected files silcd/server.[ch].
412 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
416 * Fixed the NICK command to always give the unformatted
417 nickname to the one giving the NICK command. If unformatted
418 nickname is cached already it will be formatted and the
419 local entry will always get the unformatted nickname.
420 Affected file lib/silcclient/idlist.c.
422 * Fixed some double frees from client library commands.
423 Affected file is lib/silcclient/command.c.
425 * Fixed CUMODE command in server to assure that no one can
426 change founder's mode than the founder itself, there was a
427 little bug. Affected file silcd/command.c.
429 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
431 * Removed the SilcClientCommandDestructor from the client
432 libary, it is not needed anymore. Affected files are
433 lib/silcclient/silcapi.h, command[_reply].[ch],
434 client_notify, idlist.c.
436 * Fixed GETKEY command to first resolve client, and then
437 resolve the server only if the client was not found, instead
438 of resolving both at the same time. Affected file is
439 lib/silcclient/command.c.
441 * Added silc_client_start_key_exchange_cb and lookup the
442 remote hostname and IP address before starting the key
443 exchange with server. The affected file is
444 lib/silcclient/client.c.
446 * The server's public key is now saved using the IP address
447 of the server and not the servername for the filename.
448 The hostname public key filename is checked as an fall back
449 method if the IP address based filename is not found.
451 Fixed the GETKEY command to save the fetched server key
454 Print the remote server's hostname now when new key is
455 received during connection process. Affected file is
456 irssi/src/silc/core/client_ops.c.
458 * Return always our own public key to the client if it asks
459 for it with GETKEY command. Affected file silcd/command.c.
461 * Removed the use_auto_addr variable from default config
462 file since it was in wrong section. Affected file is
465 * Fixed TOPIC_CHANGE notification to not route it when it
466 was sent using silc_server_send_notify_to_channel function.
467 Affected file silcd/command.c.
469 * Fixed silc_server_send_notify_kicked to send the kicker's
470 Client ID also, it was missing. Affected files are
471 silcd/command.c, silcd/packet_send.[ch].
473 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
475 * Do not save client history information in SERVER_SIGNOFF.
476 Fixes the bug in normal server that it does not detect
477 the client becoming valid after the server becomes back
478 online. Affected file silcd/server_util.c.
480 * Added `sock_error' field into the SilcSocketConnection
481 context. When error occurs during socket operation (read
482 or write) the error is saved. Added also new function
483 silc_socket_get_error to return human readable socket error
484 message. Affected files are lib/silcutil/silcsockconn.[ch],
485 lib/silcutil/unix/silcunixsockconn.c, and
486 lib/silcutil/win32/silcwin32sockconn.c.
488 * The server now prints the socket error message in the
489 signoff for client. Affected file silcd/server.c.
491 * Fixed the `created' channel information sending from router
492 to server in JOIN command. Checks now whether the channel
493 really was created or not and set it according that.
495 Fixed the JOIN command to use the client entry's current
496 ID during the joining procedure instead of the one it sent
497 in the command (it is checked though), since it can change
498 between the packet processing and command processing, and
499 would just case unnecessary pain in the client end. Affected
500 file silcd/command.c.
502 * Fixed a channel key payload sending to use correct channel
503 ID when the server was forced to change the channel's ID by
504 router. Router sent the key payload with the old Channel ID.
505 Affected file silcd/packet_receive.c.
507 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
509 * Call silc_server_save_channel_key only if the key payload
510 was provided in the JOIN command's command reply. Affected
511 file silcd/command_reply.c.
513 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
515 * Fixed silc_mp_sizeinbase to return the value correctly with
516 MPI. Affected file lib/silcmath/mp_mpi.c.
518 * Fixed the stop_server signal to correctly stop the scheduler
519 and gracefully stop the server when SIGTERM or SIGINT signals
520 are received. Affected file silcd/silcd.c.
522 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
524 * Simple handling of TERM and HUP signals. Also added some log
525 flushing call around. Affected file is
528 * Fixed small bugs in silclog.c. Now buffering output will take
529 effect after 10 seconds since startup: This will ensure that
530 no important startup messages are lost. Also output redirection
531 will preserve original format ([Date] [Type] message).
532 Affected file is lib/silcutil/silclog.c.
534 * Added two options to the config file, in the logging section:
535 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
536 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
538 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Do not print the warning about log files not being initialized
541 more than once to avoid excess logging. Affected file is
542 lib/silcutil/silclog.c.
544 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
545 the SIM copying in make install in Makefile.am.pre.
547 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
549 * Rewritten silclog APIs. Globally interesting changes follows:
550 silc_log_set_files() changed to silc_log_set_file().
551 silc_log_set_callbacks() changed to silc_log_set_callback().
552 ROBOdoc documented silclog header file.
553 SilcLogCb now returns bool to wether inihibit the default
554 handler or not (to keep the old behaviour return always TRUE).
555 The new APIs should also fix the problem of the
556 silcd_error.log file that was written in the current directory.
559 Log files streams will remain opened after silc_log_set_file()
560 call, means less CPU usage notably on high traffic servers.
561 File streams are now full buffered, and flushed to the disk
562 every 5 minutes, lesses HD activity and CPU usage.
563 Messages can be redirected, allowing admins to configure
564 one single logfile for all server messages.
565 the silc_log_quick global variable to activate fast-logging.
566 Affected files lib/silcutil/silclog.[ch]
568 * Changed some code to conform new silclog APIs. Affected
569 files are doc/example_silcd.conf.in, silcd/server.c
570 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
573 * Fixed a memory leak that could occur in some situations.
574 Affected file silcd/serverconfig.c.
576 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
578 * Added the silc_client_del_client to remove the client from
579 all channels as well. Affected file lib/silcclient/idlist.c.
581 * Fixed the client library to correctly remove the client
582 from all channels when the client entry is being destroyed.
583 Affected file lib/silcclient/client_notify.c, command.c.
585 * Added auto-nicking support to the client library. If the
586 applicatio now sets client->nickname it will be sent to the
587 server after connecting by the library. This way for example
588 SILCNICK (or IRCNICK) environment variables will have effect
589 and always change the nickname automatically to whatever
590 it is wanted. Affected file lib/silcclient/client.[ch].
592 * Renamed silc_server_command_bad_chars to the
593 silc_server_name_bad_chars and moved it to the
594 silcd/server_util.[ch]. Added also new function
595 silc_server_name_modify_bad to return nickname that
596 includes bad characters as new nickname without those
597 bad characters. This check and modify is now used in
598 silc_server_new_client when the username is initially set
599 as nickname, so it must be checked to be valid nickname.
600 Affected file silcd/packet_receive.c.
602 * The nickname length is now taken from the packet for real
603 and not trusted to strlen() since it clearly can return
604 wrong length for nickname including bad characters. This
605 also applies to channel names. Affected file silcd/command.c.
607 * Removed the lib/silcsilm/modules directory. Modules are now
608 compiled into the lib/silcsim. Fixed the copying of the
609 modules to follow symbolic links in Makefile.am.pre.
611 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
613 * Fixed silc_string_regexify list creation. Fixes bugs with
614 BAN and INVITE commands in server. The affected file is
615 lib/silcutil/unix/silcunixutil.c.
617 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Removed the command destructor entirely from the server's
620 command and command reply routines. It is not needed, and
621 its usage was buggy and caused crashes. Affected files are
622 silcd/command[_reply].[ch].
624 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Cancel protocol and NULL sock->protocol if timeout
627 occurred during protocol. Affected file silcd/server.c.
629 * Cancel protocol timeouts always before calling the final
630 callback, to assure that after final callback is called
631 no other state will be called for the protocol anymore.
632 Affected file silcd/protocol.c.
634 * Print error log if incoming connection configuration could
635 not be found. Affected file silcd/server.c.
637 * Fixed JOIN command to correctly save the founder mode
638 to the client on normal SILC server, when the channel
639 was created by the router. Affected file silcd/command.c.
641 * Fixed LIST command (hopefully) to send correct reply
642 packets. Affected file silcd/command.c.
644 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
646 * The silc_packet_receive_process now returns FALSE if the
647 read data was invalid packet, and TRUE if it was ok.
649 The server now checks that if unauthenticated connection
650 sends data and its processing fails the server will close
651 the connection since it could be a malicious flooder.
653 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
655 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
657 * Make sure the warning about error opening a log file is
658 printed only once and not everytime it fails (produces
659 too much useless log). Affected file lib/silcutil/silclog.c.
661 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
663 * Made the silc_server_daemonise() function more readable.
664 Affected file silcd/server.c.
666 * Pid file is now optional, the user may comment it out from
667 the config file. Removed define SILC_SERVER_PID_FILE, we
668 don't need a default any longer. Affected file
669 configure.in.pre, lib/Makefile.am.pre.
671 * Make some use of the pid file. The server now dies at startup
672 if it detects a valid pid file on his path. The server would
673 die anyway in this circumstance, because of the bind() failure.
674 Affected file silcd/silcd.c.
676 * No longer compiling lib/dotconf.
678 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Fixed JOIN command parsing not to crash. Affected file
681 lib/silcclient/command.c.
683 * Fied the NICK_CHANGE notify to add the new client entry
684 even it is resolved. This removes an <[unknown]> nick
685 thingy bug in the client. Affected file is
686 lib/silcclient/client_notify.c.
688 * Do not try to allocate 0 bytes (efence does not like it)
689 in lib/silccore/silccomand.c when encoding payload.
691 * Do not take IRCNICK as nickname in Irssi SILC client since
692 it is not possible to set nickname before hand connecting
693 the server (TODO has an entry about adding auto-nicking
696 * Changed the silc_server_command_pending to check whether
697 there already exists an pending entry with the specified
698 command, command identifier and pending callback. This is
699 to fix IDENTIFY and WHOIS related crashes that may register
700 multiple pending commands with same identifier. Affected
701 file silcd/command.c.
703 * Fixed the server to reconnect to the router even if it
704 was already reconnecting and EOF was received. This to
705 fix a possibility that the server wouldn't ever try to
706 auto-reconnect to the router. Affected file silcd/server.c.
708 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Fixed the server's password authentication to use the
711 length of the locally saved password, and not the one
712 sent in the packet. Affected file silcd/protocol.c.
714 * Fixed same password authentication problem in the
715 Authentication Payload handling routines in
716 lib/silccore/silcauth.c.
718 * Yet another password authentication problem fixed with
719 channel password handling in silcd/command.c.
721 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
723 * If first character of string in silc_parse_userfqdn is '@'
724 then do not parse it. Affected file is
725 lib/silcutil/silcutil.c.
727 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Fixed minor bug in IDENTIFY command reply sending, which
730 caused various weird problems during JOIN when it was
731 resolving names for users. Affected file silcd/command.c.
733 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Fixed the IDENTIFY command reply sending to chech better valid
736 clients. It was possible to send incomplete list of replies.
737 Affected file silcd/command.c.
739 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Added silc_client_command[s]_[un]register functions now to
742 dynamically register the commands in client library. Removed
743 the static table of commands. This allows the client library
744 to call commands without causing the application to know about
745 what commands library has called.
747 Removed the INFO command reply kludge to detect when the command
748 was called by library. Now library use its own command reply
749 function for INFO command.
751 Added function silc_client_command_call to call a command.
752 Application can use it to call command, not access the structure
755 Now all commands that are sent by the client library (not
756 explicitly sent by application) use own command reply functions.
758 Affected files around lib/silcclient/ and in
759 irssi/src/silc/core/.
761 * Fixed the WHOIS command reply sending to chech better valid
762 clients. It was possible to send incomplete list of replies.
764 Fixed the WHOIS and IDENTIFY to send the request to router
765 if normal server did not do it and did not find any results.
767 Affected file silcd/command.c.
769 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Moved the internal data from SilcClient context into its
772 own file, not accesible to application. Affected files
773 lib/silcclient/client.h and lib/silcclient/client_internal.h,
774 and other files in client library.
776 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Added doc/examples installation target in Makefile.am.pre.
781 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
783 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
784 commands the found client entry will be removed from the
785 cache, after notifying application about the error. Affected
786 file lib/silcclient/command_reply.c.
788 * Changed the /MSG to check for exact nickname user gave, and
789 not let `nick' match `nick@host' if it is only one found. Now,
790 user must type the exact nickname (like nick@host2) even if
791 there are no more than one same nicks found. This is to avoid
792 a possibility of sending nickname to wrong nickname since
793 `nick' could match `nick@host'. Affected file is
794 irssi/src/core/silc-servers.c.
796 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Do not print "you are now server operator" or similar when
799 giving /away command. Affected files are
800 irssi/src/silc/core/client_ops.c, silc-servers.h.
802 * Made the silc_server_command_pending_error_check to send
803 the same command reply payload it received back to the
804 original sender of the command. This way all arguments
805 that was received by the server will be received by the
806 client too. Affected file silcd/command.c.
808 * Added the silc_idcache_add to return the created cache entry
809 to a pointer. Affected file lib/silccore/silcidcache.[ch].
811 * Add global clients to expire if they are not on any channel.
812 This is because normal server will never know if they signoff
813 if they are not on any channel. The cache expiry will take
814 case of these entries. This is done by normal servers only.
815 The affected files are silcd/command_reply.c,
816 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
818 * If server receives invalid ID notification for WHOIS or
819 IDENTIFY and the ID exists in the lists, it is removed.
820 Affected file silcd/command_reply.c.
822 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
823 in client then client entry that it matches is searched and
824 the nickname is printed on the screen for user. Affected
825 file irssi/src/silc/core/client_ops.c.
827 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Use cache entry expire time in the LIST command reply to
830 purge old entries from the cache after the LIST command
831 reply has been received. This way we don't have non-existent
832 entries in the cache for too long. Affected file is
833 silcd/command_reply.c.
835 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * If we are normal server, and we've not resolved client info
838 in WHOIS or IDENTIFY from router, and it is global client,
839 we'll check whether it is on some channel. If it is not
840 then we cannot be sure about its validity and will resolve it
841 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
842 file silcd/command.c.
844 * Search channel by name (if possible) rather than by ID
845 in IDENTIFY command's command reply. Affected file is
846 silcd/command_reply.c.
848 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Distribute to the channel passphrase in CMODE_CHANGE notify.
851 Updated specs and implemented it. Affected file silcd/command.c,
852 silcd/packet_send.c and silcd/packet_receive.c.
854 * Implemented the <founder auth> payload handling in the JOIN
855 command. If provided all conditions for channel joining
856 except requirement to provide correct passphrase can be
857 overrided by the channel founder. Updated the protocol specs.
858 Affected file silcd/command.c.
860 Added support for founder auth in JOIN command in client
861 library. Fixed the parsing of the JOIN command now to support
862 all options as they should be. The affected file is
863 lib/silcclient/command.c.
865 * Optimized the WHOIS and IDENTIFY commands to send the request
866 to router only if it includes nicknames or other names. If
867 they include only IDs then check the local cache first before
868 routing. Affected file is silcd/command.c.
870 * Added channels topic announcements. Affected file is
871 silcd/packet_receive.c and silcd/server.c.
873 * Fixed the silc_server_send_notify_topic_set to really destine
874 the packet to channel. Affected file silcd/packet_send.c.
876 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
877 library. Affected file lib/silcclient/client_notify.c.
879 * Added UMODE announcements. Affected file silcd/server.c.
881 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Memory leak fixes in:
885 lib/silcutil/silcsockconn.c
886 lib/silcske/silcske.c
889 lib/silccrypt/silcpkcs.c
890 lib/silccore/silccommand.c
891 lib/silccore/silcidcache.c
896 * ROBOdoc documented the lib/silcske/groups.h file and a
897 bit changed the interface for better.
899 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
901 * Update the client entry context in the ID cache after
902 nick change. Affected file lib/silcclient/command.c.
903 Fixes the CUMODE command when regaining founder privileges,
904 and a little WHOIS problem.
906 * Fixed silc_net_gethostbyname to correctly call the
907 inet_ntop. Affected file lib/silcutil/silcnet.c.
909 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
911 * Added IPv6 support checking to the configure.in.pre, added
912 also --enable-ipv6 option to override the check. Affected
913 file configure.in.pre.
915 * The silc_thread_create now calls the start function
916 directly if threads support is not compiled in. Removes
917 ugly #ifdef's from generic code. Affected files are
918 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
920 * Added silc_net_gethostby[name/addr]_async to asynchronously
921 resolve. Affected files are lib/silcutil/silcnet.[ch].
923 * Added support for rendering IPv6 based server, client and
924 channel IDs. Affected file lib/silcutil/silcutil.c.
926 * Added support for creating IPv6 based server IDs. Affected
927 file is silcd/serverid.c.
929 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
931 * Added silc_net_gethostby[addr/name] into the
932 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
933 routines. Added silc_net_is_ip[4/6]. Affected file is
934 lib/silcutil/unix/silcunixnet.c. All routines that take
935 address as argument now supports both IPv4 and IPv6 addresses.
937 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
939 * Fixed LIST command reply sending in server. Affected file
942 * Server now sends the kicker's client ID in the KICK notify
943 to the kicked client. Affected file silcd/command.c.
945 * The client library now parses the kickers client ID and
946 UI displays it. Affected files lib/silcclient/client_notify.c
947 and irssi/src/silc/core/silc-channels.c, module-formats.c.
949 * Made all payload parsing function prototypes consistent.
950 They all take now const unsigned char * and uint32 pair as
951 the payload data instead of SilcBuffer. Changes all around
952 the source tree. Other unsigned char* -> const unsigned char*
953 changes around the tree as well.
955 * Optimized SFTP client and server packet sending not to
956 allocate new buffer for each packet but to recycle the
957 first allocated buffer. Affected files are
958 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
960 * Optimized the SFTP client to use SilcList instead of
961 SilcDList for requests, because it is faster. Affected file
962 is lib/silcsftp/sftp_client.c.
964 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
965 into lib/silccore/silcid.[ch].
967 Renamed silcpayload.[ch] into silcargument.[ch].
969 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
971 * If client entry is deleted with active key agreement
972 session, abort the session.
974 The silc_client_abort_key_agreement now calls the completion
975 callback with new SILC_KEY_AGREEMENT_ABORTED status.
977 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
980 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Don't use __restrict in older GCC's. Affected file is
983 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
985 * silc_net_localhost now attempts to reverse lookup the
986 IP/hostname. Affected file lib/silcutil/silcnet.c.
988 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
989 command. It can be used to gain founder privileges at
990 the same time when joining the channel.
992 Defined that the SILC_NOTIFY_TYPE_KICKED send the
993 kicker's client ID as well. Updated protocol specs.
995 Defined that the server must send SILC_COMMAND_IDENTIFY
996 command reply with error status to client who sent
997 private message with invalid client ID.
999 Updated the protocol specification.
1001 * Added silc_server_send_command_reply to send any
1002 command reply. Affected file silcd/packet_send.[ch].
1004 * Added silc_id_payload_encode_data to encode ID payload
1005 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1007 * The server now send IDENTIFY command reply with error
1008 status if client ID in private message is invalid. Affected
1009 file silcd/packet_receive.c.
1011 * Save the server key file with server's IP address in
1012 the filename instead of hostname. The affected file is
1013 irssi/src/silc/core/client_ops.c.
1015 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1020 * Added libtool support for compiling shared objects in
1021 lib/silcsim. Affected file configure.in.pre and
1022 lib/silcsim/Makefile.am. Original patch by cras.
1024 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Pid file configuration, and server's config file fixes
1027 patch by toma. Updated CREDITS file.
1029 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Fixed silc_client_channel_message to not try to decrypt
1032 the message twice if it resolved the destination client
1033 information. This could cause of dropping one channel
1034 message. Affected file lib/silcclient/client_channel.c.
1036 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1038 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1039 lib/silcclient/client.c. This function is used when the SILC
1040 Client is run under some other scheduler, or event loop or
1041 main loop. On GUI applications, for example this may be
1042 desired to used to run the client under the GUI application's
1043 main loop. Typically the GUI application would register an
1044 idle task that calls this function multiple times in a second
1045 to quickly process the SILC specific data.
1047 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1049 * Fixed silc_server_drop() for dropping the supplementary
1050 groups as well, this could cause a security hole on some
1053 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1058 * Write PID file after dropping privileges. Added -F option
1059 to run server on foreground. A patch by debolaz.
1060 Affected files silcd/server.c, silcd/silcd.c.
1062 * Fixed MOTD to return the MOTD file server name. Affected
1063 file silcd/command.c.
1065 * Added INFO command reply handling to the Irssi SILC Client.
1066 Affected file irssi/src/silc/core/client_ops.c.
1068 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Fixed the silc_idcache_list_* routines to really support
1071 the dynamic list. Fixes a crash. Affected file is
1072 lib/silccore/silcidcache.c.
1074 * Fixed the LIST command reply to really call LIST command's
1075 pending callbacks. Affected file silcd/command_reply.c.
1077 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Update conn->local_entry->nickname after giving NICK
1080 command. Affected file lib/silcclient/command.c.
1082 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1084 * Added the [pid] option to the silcd configuration file
1086 Affected files: serverconfig.[ch] and silcd.c
1088 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1090 * Save fingerprint in WHOIS command reply in server.
1091 Affected file silcd/command_reply.c.
1093 * Fixed NICK commands pending callback registration.
1094 Affected file lib/silcclient/command.c.
1096 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Use ++server->cmd_ident when sending commands in server,
1099 instead of random number. Affected file silcd/command.c.
1101 * Fixed GETKEY command reply to call actually GETKEY pending
1102 command callbacks. Affected file silcd/command_reply.c.
1104 * A bit stricter check for nicknames. Check for same nickname
1105 in NICK command also. Affected file silcd/command.c.
1107 * Do not call INFO command everytime client ID changes, only
1108 during first connecting. Affected file lib/silcclient/client.c.
1110 * Set the new nickname only after successful command reply for
1111 NICK command is returned by server. Affected file
1112 lib/silcclient/command.c.
1114 * Remove nicknames from nicklist during server_signoff notify.
1115 Should fix /NAMES bit more. The affected file is
1116 irssi/src/silc/core/silc-channels.c.
1118 * Added `fingerprint' field to the SilcIDListData in the
1119 silcd/idlist.h to hold the fingerprint of the client's
1122 Send the fingerprint of the client's public key in WHOIS
1125 Affected files silcd/command.c, and silcd/idlist.[ch].
1127 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1128 create fingerprint from given data.
1130 * Show the fingerprint of the client's public key in WHOIS.
1131 Affected files irssi/src/module-formats.[ch] and
1132 irssi/src/silc/core/client_ops.c.
1134 * Format the multiple same nicknames also during JOIN and
1135 NICK_CHANGE notifys. Affected file is
1136 lib/silcclient/client_notify.c.
1138 * Do not print error on screen for invalid private message
1139 payload since it can come if someone is sending private
1140 messages with wrong key. Affected file
1141 lib/silccore/silcprivate.c.
1143 * Fixed multiple concurrent /PING crash. Affected file
1144 lib/silcclient/command.c.
1146 * Changed the wrong ID encoding. All IP addresses must be
1147 in MSB first order in encoded format. They were encoded
1148 wrong and was in LSB format. Affected files are
1149 silcd/serverid.c, lib/silcutil/silcutil.c.
1151 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1153 * Call the `connect' client operation through the scheduler
1154 in case of error. Affected file lib/silcclient/client.c.
1156 * Call the `failure' client operation even if the error
1157 occurred locally during a protocol. Affected file is
1158 lib/silcclient/protocol.c.
1160 * Added support of sending LIST command to router from normal
1161 server. This way normal server can get list of all channels
1162 in the network too. Fixed the channel list sending in the
1163 server too. Affected files are silcd/command.c, and
1164 silcd/command_reply.[ch].
1166 * Added silc_server_update_channels_by_server and
1167 silc_server_remove_channels_by_server. They are used during
1168 disconnection of primary router and in backup router protocol.
1169 Affected file silcd/server_util.[ch], silcd/server.c and
1170 silcd/server_backup.c.
1172 * Fixed channel adding to global list in IDENTIFY command
1173 reply in server. Affected file silcd/command_reply.c.
1175 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * If the incoming packet type is REKEY or REKEY_DONE process
1178 that packet always synchronously. Fixes yet another MAC
1179 failed error on slow (dialup) connections. Affected file
1180 lib/silcclient/client.c and silcd/server.c.
1182 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Call check_version SKE callback for initiator too. Affected
1185 file lib/silcske/silcske.c.
1187 * Implemented fix for security hole found in the SKE that was
1188 fixed in the specification few days back; the initiator's
1189 public key is now added to the HASH value computation.
1190 Added backwards support for the old way of doing it too, for
1191 old clients and old servers. Affected file is
1192 lib/silcske/silcske.c.
1194 * Enabled mutual authentication by default in SKE. If initiator
1195 is not providing mutual authentication the responder will
1196 force it. This will provide the proof of posession of the
1197 private key for responder. The affected files are
1198 lib/silcclient/protocol.c and silcd/protocol.c.
1200 * Do not cache anymore the server's public key during SKE.
1201 We do mutual authentication so the proof of posession of
1202 private key is done, and if the server is authenticated in
1203 conn auth protocol with public key we must have the public
1204 key already. Affected file silcd/protocol.c.
1206 * Added new global debug variable: silc_debug_hexdump. If
1207 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1208 file lib/silcutil/silclog.[ch].
1210 * Fixed compilation warning due to char * -> const char *.
1211 Affected files lib/silcutil/silcnet.h, and
1212 lib/silccore/silcauth.[ch].
1214 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * Fixed CMODE command when new channel key was created. If
1217 the creation failed the old key was removed. Next time giving
1218 same command would crash the server since the old key was
1219 freed already. Affected file silcd/command.c.
1221 * Fixed the silc_server_announce_get_channels to not crash
1222 on reconnect. Affected file silcd/server.c.
1224 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Added silc_log_set_debug_string function to set a regex
1227 string to match for debug output. Only the function names,
1228 or filenames matching the given debug string is actually
1229 printed. This way it is possible to filter out those debug
1230 strings that user is not interested in.
1232 Fixed a bug in silc_string_regexify.
1234 Affected files lib/silcutil/silclog.[ch], and
1235 lib/silcutil/unix/silcunixutil.c.
1237 * Changed the -d options in both server and Irssi SILC client
1238 to take the debug string as argument. Affected files
1239 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1241 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Added silc_hash_babbleprint to create a Bubble Babble
1244 Encoded fingerprint. The encoding is developed by Antti
1245 Huima (draft-huima-babble-01.txt), and it creates human
1246 readable strings out of binary data. Affected file
1247 lib/silccrypt/silchash.[ch].
1249 * Print the babble print now in addition of fingerprint as well
1250 in Irssi SILC client. Affected files are
1251 irssi/src/fe-common/silc/module-formats.[ch],
1252 irssi/src/fe-common/silc/core/client_ops.c.
1254 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1256 * Fixed a security problem found in SKE. The initiator's
1257 public key too is now added to the HASH hash value creation
1258 which is signed by the responder to create the SIGN value.
1259 This will prevent anyone in the middle to lie to the responder
1260 about the initiator's public key. If this is done now, the
1261 man in the middle will get caught. Updated the protocol
1264 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Better installation directory handling. Configure module
1267 paths and other paths automatically to example_silc* files
1268 in doc/. A patch by toma.
1270 * Fixed compiler warning from MPI library, and from SILC RNG.
1273 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1274 It can be configured with ./configure. A patch by toma.
1276 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Find correct make to use in prepare-clean. A patch by
1279 toma. Affected file prepare-clean.
1281 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1283 * Added irssi variables use_auto_addr, auto_bind_ip,
1284 auto_bind_port and auto_public_ip.
1286 * Changed the interface for silc_client_send_key_agreement
1287 in lib/silcclient/silcapi.h
1291 irssi/src/silc/core/silc-core.c
1293 lib/silcclient/silcapi.h
1294 irssi/src/silc/core/silc-channels.c
1295 lib/silcclient/client_keyagr.c
1298 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Added silc_pkcs_public_key_compare to compare two
1301 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1303 * Check that the client who set the founder mode on the
1304 channel is the same client that is giving the founder
1305 mode to itself. It is done by comparing the saved public
1306 key (it is saved even in the authentication is passphrase).
1307 Affected file silcd/command.c.
1309 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Do not process packet for disconnected socket connection.
1312 Affected file lib/silccore/silcpacket.c.
1314 * Process the DISCONNECT packet through scheduler in the
1315 client library. Affected file lib/silcclient/client.c.
1317 * Fixed the silc_client_packet_parse to not to increase
1318 the packet sequence number if the conn->sock and the
1319 current socket connection is not same. This can happen
1320 for example during key agreement when the conn includes
1321 multiple socket connections (listeners). Affected file
1322 lib/silcclient/client.c.
1324 * The sender of the file transfer request now provides also
1325 the pointer (listener) for the key exchange protocol. If
1326 the listener cannot be created then it sends empty key
1327 agreement and lets the receiver provide the listener.
1329 Added `local_ip' and `local_port' arguments to the
1330 silc_client_file_send. If they are provided they are used,
1331 if not then it will attempt to find local IP address, if
1332 not found or bind fails then the remote client will provide
1335 Affected files are lib/silcclient/client_ftp.c and
1336 lib/silcclient/silcapi.h.
1338 * Extended the FILE SEND command to support defining the
1339 local IP and port for key exchange listener. They are
1340 optional. Affected file irssi/src/silc/core/silc-servers.c.
1342 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Defined to WHOIS command reply the sending of fingerprint
1345 of the client's public key (if the proof of posession of the
1346 corresponding private key is verified by the server).
1347 Updated to the protocol specification.
1349 * Added support of receiving the client's public key's
1350 fingerprint in command reply in client library. Affected
1351 file is lib/silcclient/command_reply.c, and
1352 lib/silcclient/idlist.[ch].
1354 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Do not send over 128 chars long nickname to the server
1357 in NICK command. Affected file lib/silcclient/command.c.
1359 * Do not send over 256 chars long channel names to the server
1360 in JOIN command. Affected file lib/silcclient/command.c.
1362 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Assure that silc_server_close_connection cannot be called
1365 twice for same socket context. Affected file is
1368 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Send error message to application if opening file for
1371 writing during file transfer fails. Affected file is
1372 lib/silcclient/client_ftp.c.
1374 Remove all file transfer sessions for a client that we're
1375 removing from ID cache.
1377 Affected file is lib/silcclient/client_ftp.c.
1379 * Fixed silc_net_addr2bin to return correct address. Affected
1380 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1382 * Fixed file transfer session removing on signoff notify.
1383 Affected file irssi/src/silc/core/silc-servers.c.
1385 * Added the SilcClientFileError to be returned in the monitor
1386 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1387 Affected file lib/silcclient/silcapi.h.
1389 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Fixed a crash in silc_client_ftp_free_sessions and
1392 silc_client_ftp_session_free_client. Affected file
1393 lib/silcclient/client_ftp.c.
1395 * Added `disabled' field in the SilcChannelEntry in the server
1396 to indicate if the server entry is disabled. Affected file
1397 silcd/idlist.h, silcd/command[_reply].c.

1400 started. Affected file silcd/silcd.c.
1402 * Added silc_server_packet_send_clients to send a packet to
1403 the provided table of client entries. Affected file
1404 silcd/packet_send.[ch].
1406 * Fixed a crash in client resolving in client_prvmsg.c in
1407 client library. Affected file lib/silcclient/client_prvmsg.c.
1409 * Do not actually remove the client directly from ID cache
1410 during SERVER_SIGNOFF, but invalidate it. This way we
1411 preserve the WHOWAS info for the client. Affected file
1412 silcd/server_util.c.
1414 * Fixed SERVER_SIGNOFF notify handling in the server. The
1415 server is now able to process incoming SERVER_SIGNOFF notify
1416 for a server that it doesn't even know about. It will remove
1417 the clients provided in the notify. Affected file
1418 silcd/packet_receive.c.
1420 * Check for partial packet in data queue after every packet that
1421 was found from the queue. Return and wait for more data if
1422 there is partial data in queue. Affected file is
1423 lib/silccore/silcpacket.c.
1425 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added SilcClietFileError enum to indicate error in
1428 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1429 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1430 Affected files lib/silcclient/silcapi.h and
1431 lib/silcclient/client_ftp.c.
1433 * Check that newsize in silc_buffer_realloc is larger than
1434 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1436 * Added better monitor of file transfers. It now monitors
1437 key agreement protocol during the file transfer too. Added
1438 error reporting too. Affected files
1439 irssi/src/silc/core/silc-servers.c,
1440 irssi/src/fe-common/silc/module-formats.[ch].
1442 * Wrote a help file for FILE command.
1444 * Added silc_rng_global_get_byte_fast to get not-so-secure
1445 random data as fast as possible. Random data is read from
1446 /dev/urandom if available and from the SILC RNG if not
1447 available. It is used in padding generation. Affected file
1448 lib/silccrypt/silcrng.[ch].
1450 * All packets in client library are now processed synchronously.
1451 Optimized packet processing a lot. Affected file
1452 lib/silcclient/client.c.
1454 * All server connection packets are processing synchronously
1455 now in server, to optimize packet processing. Affected file
1458 * Include files are installed now only in Toolkit distribution
1459 if make install is given. Affected files: all Makefile.am's.
1461 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Assure that silc_client_notify_by_server_resolve does not
1464 resolve the client information multiple times. If it cannot
1465 be found by the first it cannot be found at all. Affected
1466 file lib/silcclient/client_notify.c.
1468 * Fixed WHOWAS command reply calling. Affected file
1469 lib/silcclient/command_reply.c.
1471 * Removed all references to silc_idlist_get_client from the
1472 Irssi SILC client since that call is internal call used by
1473 the library. The Irssi SILC client will use now client
1474 retrieval functions found in silcapi.h.
1476 * Fixed a bug in resolving nickname info before sending
1477 private message. It used freed memory. Affected file
1478 irssi/src/silc/core/silc-servers.c.
1480 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Assure my_channels statistics cannot go negative in server.
1483 Affected files silcd/server.c, silcd/server_util.c.
1485 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1489 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1495 lib/sftp/sftp_fs_memory.c.
1497 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Added silc_net_localip to return local host's IP address.
1500 Affected file lib/silcutil/silcnet.[ch].
1502 * If key exchange or rekey protocol is active for a connection
1503 parse all packets syncronously since there might be packets
1504 in packet queue that we are not able to process without first
1505 processing packets before them. Affected file silcd/server,
1506 lib/silcclient/client.c.
1508 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1509 whether library should continue processing the packet.
1510 Affected file lib/silccore/silcpacket.h.
1512 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1513 SilcSFTPMonitorData to SFTP server to monitor various
1514 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1515 lib/silcsftp/sftp_server.c.
1517 * Added silc_file_size to return file size. Affected file

1522 transmission. Affected file lib/silcclient/client_ftp.c,
1523 lib/silccilent/client.[ch].
1525 * Added new local command FILE to the Irssi SILC Client.
1526 It is used to perform the file transfer. It has subcommands
1527 SEND, RECEIVE, SHOW and CLOSE. Affected files
1528 irssi/src/silc/core/client_ops.c,
1529 irssi/src/silc/core/silc-server.[ch].

1538 * Renamed silc_file_read and silc_file_write to functions
1539 silc_file_readfile and silc_file_writefile. Added function
1540 silc_file_open and silc_file_close. Affected files
1541 lib/silcutil/silcutil.[ch].
1543 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Resolve the client info when received private message or
1546 channel message for a client which nickname we don't know.
1547 Affected files lib/silcclient/client_prvmsg.c and
1548 lib/silcclient/client_channel.c.
1550 * Do not crash in /KEY if client is not connected. Affected
1551 file irssi/src/silc/core/silc-channels.c.
1553 * Added SilcClientStatus field to the SilcClientEntry in the
1554 lib/silcclient/idlist.h.
1556 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1557 is incomplete and is being resolved, it won't be resolved
1560 Make sure also that USERS command reply does not resolve
1561 twice information. Affected file is
1562 lib/silcclient/command_reply.c.
1564 Make sure that silc_client_get_clients_by_list does not
1565 resolve twice same information.
1567 * Check for valid client->id in the silc_server_free_client_data.
1568 Affected file silcd/server.c.
1570 * Fixed /GETKEY nick@server not to crash if the server entry
1571 is not found. Affected file lib/silcclient/command.c.
1573 * Fixed the silc_server_check_cmode_rights to check the
1574 requested modes correctly. Affected file silcd/command.c.
1576 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1578 * Better checks for non-printable chars in nick added.
1579 Affected file silcd/command.c.
1581 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Call the silc_server_udpate_servers_by_server in the
1584 primary router that comes back online in the backup resuming
1585 protocol. Otherwise it routes packets wrong. Affected file
1586 silcd/server_util.[ch], silcd/server_backup.c.
1588 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1591 lib/silcutil/silcbuffmt.[ch].
1593 * Redefined the SILC packet header to include the padding
1594 length. Affected file lib/silccore/silcpacket.[ch].
1596 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1597 length for maximum padding up to 128 bytes). Affected
1598 file lib/silccore/silcpacket.h.
1600 * Removed all backwards support for old 0.5.x MAC thingies.
1601 The SILC packet header change makes it impossible to be
1602 backwards compatible.
1604 * Send the ENDING packet with timeout in the backup resuming
1605 protocol. This is to assure that all routers has connected
1606 to the primary router. Affected file silcd/server_backup.c.
1608 * Changed the RNG to take the first IV from random data. It
1609 used to take it from zero actually. Changed the RNG also
1610 to use /dev/urandom during session. /dev/random is used
1611 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1613 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Changed the SILC packet header to have the first two bytes
1616 (the packet length) encrypted. Affected files aroung the
1617 code tree, lib/silccore/silcpacket.[ch]. Removed the
1618 SilcPacketCheckDecrypt callback. It is not needed anymore
1619 since the silc_packet_receive_process will determine now
1620 whether the packet is normal or special.
1622 * Implemented the unidirectional MAC keys. Affected files
1623 lib/silcske/silcske.c, silcd/protocol.c and
1624 lib/silcclient/protocol.c.
1626 * Implemented the packet sequence number to the MAC computation.
1627 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1628 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1629 lib/silcclient/protocol.c.
1631 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Allow backup router to announce servers. All servers
1634 announced by backup router are added to the global list
1635 automatically. Update hte server's socket to our primary
1636 router also when backup router announces a server.
1637 Affected file silcd/packet_receive.c.
1639 * Do not update the client->router in the function
1640 silc_server_udpate_clients_by_server if the client is on
1641 global list. We might fail to find any specific server
1642 for locally connected clients and local cell clients. They
1643 should still use the `from' and not `to' as client->router.
1644 This fixes backup router resuming protocol. Affected file
1645 silcd/server_util.c.
1647 * Decrease channel statistics count only if the channel
1648 deletion worked. Affected files are silcd/server.c and
1649 silcd/server_util.c.
1651 * Added silc_server_update_servers_by_server to update origin
1652 of all server entries. Used during backup router protocol.
1653 Affected files silcd/server_util.[ch], silcd/server.c. and
1654 silcd/backup_router.c.
1656 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1657 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1658 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1659 lib/silccrypt/silchmac.c.
1661 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Assure that router cannot reroute the same channel message
1664 to the sender. Affected file silcd/packet_receive.c.
1666 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Made better checks that the channel message is not sent
1669 to the router it came from. Affected file is
1670 silcd/packet_send.c. Fixed memory leak too.
1672 * Announce informations for incoming router connection, but
1673 only after checking if it is replaced by backup router.
1674 Affected file silcd/packet_receive.c.
1676 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed the backup resuming protocol to work in multiple
1679 router environment. Affected file silcd/server_backup.c.
1681 * Route packet only to one router in the function
1682 silc_server_packet_send_to_channel. Affected file is
1683 silcd/packet_send.c.
1685 * Fixed silc_server_send_notify_dest to set the broadcast
1686 flag. Fixed the silc_server_send_notify_topic to actually
1687 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1688 Affected file silcd/packet_send.c.
1690 * Changed the SFTP Filesystem interface. Changed the
1691 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1692 the filesystem operation function. The SilcSFTPFilesystem
1693 is now a context that is allocated by all filesystem allocation
1694 functions and it already includes the operations structure
1695 and filesystem specific context. It is given as argument
1696 now to the silc_sftp_server_start. This made the interface
1697 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1698 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1700 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Changed the backup router adding and getting interfaces
1703 in the server. The router that will be replaced by the
1704 specified backup router is now sent as argument. Affected
1705 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1708 * Added silc_net_addr2bin_ne to return the binary form of
1709 the IP address in network byte order. Affected files
1710 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1712 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Check for existing server ID in silc_server_new_server
1715 and in silc_server_connect_to_router_final and remove the
1716 old entry if it exists. Affected file silcd/packet_receive.c,
1719 * Send the channel message always to only one router, either
1720 in upstream or downstream. Affected file is
1721 silcd/packet_send.c.
1723 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Wrote the definition of the backup resuming protocol to the
1726 protocol specification.
1728 * Removed one redundant channel key generation from normal
1729 server during joining procedure. Removed one redundant
1730 channel key sending from server to router during joining
1731 procedure. Affected file silcd/command.c.
1733 * Made minor bugfixes to the backup router resuming protocol.
1734 Affected file silcd/server_backup.c, server.c.
1736 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Added --disable-asm configuration option. Affected files
1739 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1742 * Implemented the backup resuming protocol that is used to
1743 resume the primary router position in the cell after the
1744 primary router comes back online. Affected files
1745 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1746 and silcd/server_util.[ch].
1748 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Sleep two (2) seconds after sending QUIT command to server.
1751 Affected file lib/silcclient/command.c.
1753 * Assure that if outgoing data buffer is pending do not force
1754 send any data. Affected file silcd/packet_send.c.
1756 * Assure that if outgoing data buffer is pending do not force
1757 send any data. Affected file lib/silcclient/client.c.
1759 * Implemented the backup router support when the primary router
1760 goes down. The servers and routers can now use the backup
1761 router as new primary router without loosing connectivity.
1763 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1766 in the server to indicate disabled entry. All data read
1767 from the connection will be ignored and no data is sent
1768 for entry that is disabled. Affected files are
1769 silcd/idlist.h, silcd/server.c.
1771 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Created SFTP client and server test programs in the
1774 lib/silcsftp/tests directory.
1776 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Implemented memory filesystem (virtual filesystem) for
1779 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1782 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Implemented the SFTP (SSH File Transfer Protocol) to the
1785 lib/silcsftp. It includes SFTP client and SFTP server
1788 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Moved lib/silccore/silcprotocol.[ch] to the
1791 lib/silcutil library.
1793 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1794 take variable argument list pointer as argument. Affected
1795 file lib/silcutil/silcbuffmt.[ch].
1797 * Added silc_buffer_set function that is used to set data
1798 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1799 Affected file lib/silcutil/silcbuffer.h.
1801 * Changed various routines in the core library to use the new
1802 silc_buffer_set instead of allocating new buffer only for
1805 * Added 64-bit value formatting and unformatting support to the
1806 silc_buffer_[un]format routines. Affected file is
1807 lib/silcutil/silcbuffmt.[ch].
1809 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1810 to includes/bitmove.h.
1812 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed channel user mode saving in client library. Affected
1815 file lib/silcclient/command[_reply].c.
1817 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Defined the file transfer to the SILC Protocol. Added
1820 new packet type SILC_PACKET_FTP and defined File Transfer
1821 Payload. The mandatory file transfer protocol is SFTP
1822 (SSH File Transfer Protocol). Affected file in addition
1823 of the internet draft is lib/silccore/silcpacket.h.
1825 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1826 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1827 is used as part of backup router protocol when the primary
1828 router of the cell is back online and wishes to resume
1829 the position as primary router.
1831 * Redefined the MAC generation keys in the protocol. The
1832 same key is not used anymore in both direction. Both
1833 direction will now use different keys for sending and
1834 receiving. This fixes a potential security flaw. This
1835 change causes incompatibilities in the protocol.
1837 * Redefined also the MAC computation from the packet.
1838 An packet sequence number is now added to the MAC
1839 computation. This prevents possible replay attacks against
1840 the protocol. This change too causes incompatibilities
1843 Added `sequence' field to the SilcPacketContext to hold
1844 the current sequence number for the packet.
1846 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Added `created' field to the SilcIDListData in the file
1849 silcd/idlist.h to indicate the time when the entry was
1852 * Added `created' field to the SilcChannelEntry too. Affected
1853 file silcd/idlist.h.
1855 * Added `creation_time' aguments to all the announcement functions
1856 in the server. If it is provided then only the entries that
1857 was created after the provided time frame are actually
1858 announced. Affected file silcd/server.[ch].
1860 * The protocol says that the Channel ID's IP address must be
1861 based on the router's IP address. Added check for this in
1862 the silc_server_new_channel when processing incoming New Channel
1863 Payload. Affected file silcd/packet_receive.c.
1865 * Print out the correct version with --version in SILC client.
1866 Affected file irssi/src/silc/core/silc-core.c.
1868 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Fixed WHOWAS command to check for completnes of the client
1871 entry always, not just when the command is coming from client.
1872 Affected file silcd/command.c.
1874 * Added new function silc_server_packet_queue_purge to purge the
1875 outgoing data queue to the network. After the function returns
1876 it is guaranteed that the outgoing packet queue is empty.
1877 Affected file silcd/packet_send.[ch].
1879 * Purge the outgoing packet queue in the rekey protocol's final
1880 callback to assure that all rekey packets go to the network
1881 before quitting the protocol. Affected file silcd/server.c.
1883 * Added silc_client_packet_queue_parse as similar function as
1884 in server to the client library. The affected file is
1885 lib/silcclient/client.c.
1887 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Splitted silcd/server.c and created silcd/server_util.[ch]
1890 for utility functions.
1892 * Added new socket flag SILC_SF_DISABLED to indicate that the
1893 connection is open but nothing can be sent to or received from
1894 the connection. Affected file lib/silcutil/silsockconn.[ch].
1895 The checking for disabled socket is checked in the low level
1896 silc_socket_write and silc_socket_read functions.
1898 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Allow only nicknames and channel names that fits into the
1901 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1903 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * When processing JOIN command reply in server check that if
1906 the channel exists in our global list we'll move it the local
1907 list. Affected file silcd/command_reply.c.
1909 * Fixed the check whether client is joined on the channel already
1910 in JOIN command. Affected file lib/silcclient/command.c.
1912 * Fixed the JOIN command reply to check whether the channel
1913 already exists. Affected file lib/silcclient/command_reply.c.
1915 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Added silc_ske_status_string to map the SKE error numbers
1918 to readable strings. The affected files are
1919 lib/silcske/silcske[_status].[ch].
1921 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1923 * Do not show the private channels on the WHOIS channel list
1924 as it is not allowed by the protocol. The affected file is
1927 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Assure that the packet length digged from the actual packet
1930 is something sensible in the silc_packet_decrypt_rest_special
1931 in lib/silccrypt/silcpacket.c.
1933 * Free and NULL the allocated pointer in silc_hmac_alloc if
1934 the HMAC allocation fails. The affected file is
1935 lib/silccrypt/silchmac.c.
1937 * Print the selected security properties to the log files in
1938 the server. Affected file silcd/protocol.c.
1940 * Add SKE's reference counter even if calling the completion
1941 callback manually. Otherwise it goes negative, although it
1942 does not cause any problems. The affected file is
1943 lib/silcske/silcske.c.
1945 * Remove the client entry with short timeout after giving the
1946 KILL command. Affected file lib/silcclient/command.c.
1948 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1949 case all found clients are already disconnected (WHOWAS would
1950 found them) in the server. Affected file silcd/command.c.
1952 * Update the last_receive (time of last data received) to be
1953 updated only when received private or channel message so that
1954 the idle time showed in WHOIS makes more sense.
1956 * Added boolean field `valid' in to the SilcClientEntry in the
1957 client library to indicate whether the entry is valid or not.
1958 This fixes the nickname change bug on channel when changing
1959 the nickname to be same than the old (like nick to Nick) the
1960 nickname formatter doesn't set the new nick anymore to Nick@host.
1961 Affected file lib/silcclient/idlist.[ch].
1963 * Now actually fixed the nickname changing on disconnection.
1964 Added new function silc_change_nick to the Irssi SILC Client.
1965 Affected file irssi/src/silc/core/client_ops.c,
1966 irssi/src/silc/core/silc-nicklist.[ch].
1968 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Check that the public key exists in the GETKEY command before
1971 trying to encode it. Affected file silcd/command.c.
1973 * Print some notifications on received public keys with GETKEY
1974 command in the Irssi SILC Client. Affected files are
1975 irssi/src/fe-common/silc/module-formats.[ch],
1976 irssi/src/silc/core/client_ops.c.
1978 * Use IDENTIFY command to resolve the server information in the
1979 GETKEY command instead of INFO command. Affected file
1980 lib/silcclient/command.c.
1982 * All command reply functions in the client library now calls
1983 the pending command reply callbacks even if an error has
1984 occurred. The server has done this a long time and now it was
1985 time to move the client library to this as well. Now all
1986 errors can be delivered back to the pending command reply
1987 callbacks if necessary. Affected files are
1988 lib/silcclient/command[_reply].[ch].
1990 * Change the nickname on disconnection back to the username
1991 because in reconnect the server will enforce it to it anyway.
1992 Affected file irssi/src/silc/core/silc-servers.c.
1994 * Fixed a config file parsing bug in the Irssi SILC client.
1995 Affected file irssi/src/silc/core/clientconfig.c.
1997 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * When printing the channel mode on JOIN, verify that the
2000 channel key and channel's HMAC are valid. Affected file
2001 irssi/src/silc/core/client_ops.c.
2003 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2006 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2007 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2009 * Removed channel key rekey task deleting from the function
2010 silc_server_save_channel_key. Affected file silcd/server.c.
2011 Added explicit timeout task context instead that is used to
2012 delete the task if we are registering a new task before the
2013 new task has elapsed.
2015 * When channel key rekey occurs the client library now saves
2016 the old channel key for a short period of time (10 seconds) and
2017 is able to use it in case some is still sending channel
2018 messages encrypted with the old key after the rekey. Affected
2019 file lib/silcclient/[idlist.h|client_channel.c].
2021 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Added check to the silc_server_new_id_real to not accept
2024 new ID if it is the sender's own ID. Affected file is
2025 silcd/packet_receive.c.
2027 * Assure that we do not announce ourself or the one we've
2028 sending our announcements when we're router and are announcing
2029 servers to our primary router. Affected file silcd/server.c.
2031 * Fixed silc_server_command_identify_check_client to assemble
2032 correct WHOIS packet. It send corrupted WHOIS packet and
2033 caused problem with router to router connections. Affected
2034 file silcd/command.c.
2036 Fixed also silc_server_command_whois_check the same way
2037 as for the IDENTIFY command.
2039 * Added new SilcIDListStatus to the server in the SilcIDListData
2040 structure. The status now includes the current status of
2041 the entry (like registered, resolved etc.). Affected file
2042 silcd/idlist.[ch]. Defined a bunch of different status types
2043 as well. This replaced the old boolean registered field as well.
2045 Added resolve_cmd_ident field to the SilcClientEntry structure
2046 too so that if the entry is for example being resolved so
2047 another command may attach to the same pending command reply
2048 without requiring to resolve the same entry again. This concept
2049 should optimize the WHOIS and the IDENTIFY resolving under
2050 heavy load by taking away unnecessary resolving for entries
2051 that are being resolved already.
2053 Added support for adding multiple pending commands for one
2054 command idenfier. Affected file silcd/command[_reply].[ch].
2056 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2057 before deleting the data. Otherwise the hash table will have
2058 freed data in comparison functions. Affected file is
2059 silcd/command_reply.c.
2061 * Fixed silc_idlist_replace_client_id to add the new entry to
2062 the cache with NULL nickname. Otherwise there will be invalid
2063 memory as the nickname after the nickname is freed. Affected
2064 file silcd/packet_receive.c.
2066 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2067 saved into wrong slots because the previous number of entries
2068 was not taken into account. Affected file silcd/idlist.c.
2069 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2071 * If we are router and we receive JOIN notify to a channel that
2072 does not have any users then notified client is marked as the
2073 channel founder, as it is it. The affected file is
2074 silcd/packet_receive.c
2076 * Added to the extended hash table API's table_del_*ext functions
2077 the destructor as argument too, so that the caller can decide
2078 which destructor to use or whether to use destructor at all.
2079 Affected file lib/silcutil/silchashtable.[ch].
2081 * Fixed ID Cache purging. It actually deleted the entries from
2082 the hash table after the data was freed. The hash table ended
2083 up comparing freed memory. The affected file is
2084 lib/silccore/silcidcache.c.
2086 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Fixed Irssi SILC client's KILL command's HELP syntax.
2090 * The USERS command now resolves the detailed user information
2091 if the userinfo field is missing. Affected file is
2092 lib/silcclient/command_reply.c.
2094 * Do not print error in silc_file_read if the read file does
2095 not exist. Just silently return NULL. Affected file is
2096 lib/silcutil/silcutil.c.
2098 * Fixed the silc_log_output to not wine about NULL filename
2099 and to not create some bogus " " filename. Affected file is
2100 lib/silcutil/silclog.c.
2102 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Fixed various printing bugs on the user interface in the
2105 Irssi SILC Client. Minor changes that were forgotten from
2108 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Fixed the configure.in.pre and the compilation and distribution
2111 environment to support the new autoconf 2.52. That version is
2112 now required to compile the CVS trunk.
2114 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2117 to generally parse user@fqdn format strings. Affected file
2118 lib/silcutil/silcutil.c.
2120 * Added nickname_format and nickname_force_format fields to the
2121 SilcClientParams structure. The first one defines the format
2122 for the nicknames that the library will enforce if the receives
2123 multiple same nicknames. The second one is boolean value and
2124 can be used to force the library to always enforce the format
2125 to the nicknames regardles whether there are multiple nicknames
2126 or not. This configurable formatting was employed to flexibly
2127 support accessing multiple nicknames from the user interface.
2128 The userinterface can now set the nicknames to what ever format
2129 they prefer. Affected file lib/silcclient/silcapi.h.
2131 Added function silc_client_nickname_format to the file
2132 lib/silcclient/idlist.c. It performs the nickname formatting.
2134 Added new field `hostname´ to the SilcClientEntry context.
2135 It holds the hostname of the client. Affected file is
2136 lib/silcclient/idlist.h.
2138 * Irssi SILC Client sets the nicknames in nick@hostn format.
2139 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2140 irssi/src/silc/core/silc-core.c.
2142 The WHOIS printing now also shows both the real nickname and
2143 the formatted nickname so that user knows how to access the
2144 user if there are multiple same nicknames cached. Affected
2145 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2146 printing formatting too to take the hostname now as a separate
2147 argument. The Affected file is
2148 irssi/src/fe-common/silc/modules-formats.[ch].
2150 * Changed the silc_client_get_clients_local to accept the formatted
2151 nickname as argument. It accepts the real nickname too but the
2152 formatted nickname can be used to find the true entry from
2153 multiple entries. Affected file lib/silcclient/silcapi.h and
2154 lib/silcclient/idlist.c.
2156 * Added nickname_format_parse field to the SilcClientParams.
2157 It is a callback function provided by the application to parse
2158 the nickname out of the formatted nickname string. The library
2159 calls it to get the nickname from the formatted string. Since
2160 the application generally knows better the format of the nickname
2161 string it parses it instead of the library, even though library
2162 encodes the formatted string. If the callback function is not
2163 provided then the library will use the string as is. The
2164 affected file is lib/silcclient/silcapi.h.
2166 * All the nickname strings passed to the client library in
2167 commands are now expected to be formatted nickname strings.
2168 If the command does not support the formatted nickname string
2169 it will assume that the sent string is the actual nickname.
2170 Affected file lib/silcclient/command.c.
2172 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Added public key authentication support to OPER and SILCOPER
2175 commands in the client library. Affected file is
2176 lib/silcclient/command.c.
2178 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Changed the get_auth_methdod client operation to be asynchronous.
2181 It can be async if the application resolves the authentication
2182 method from the server during the negotiation. Added new
2183 SilcGetAuthMeth completion callback that the application will
2184 call after resolving the authentication method.
2186 Added function silc_client_request_authentication_method that
2187 the application can use to resolve the authentication method
2188 from the server. Added also SilcConnectionAuthRequest callback
2189 that the library will call after the server has replied. The
2190 application can call this function if it does not know the
2191 current authentication method.
2193 Affected files are lib/silcclient/client.c and
2194 lib/silcclient/silcapi.h.
2196 * The Irssi SILC client now automatically resolves the authentication
2197 method incase any configuration information is not present (and
2198 currently there never is). The affected file is
2199 irssi/src/silc/core/client_ops.c.
2201 * Fixed public key authentication from the client library.
2202 Affected file lib/silcclient/protocol.c. Changed also the
2203 protocol specification about the public key authentication in
2204 the connection authentication protocol. The actual data to be
2205 signed is now computed with a hash function before signing.
2207 * Fixed the public key authentication from the server as well.
2208 Affected file silcd/protocol.c.
2210 * Removed the mlock()'s from the memory allocation routines.
2211 Affected file lib/silcutil/silcmemory.c. The ./configure does
2212 not check anymore for the mlock(). Affected file is
2215 * Fixed USERS command in server to allow the execution of the
2216 command for private and secret channels if the client sending
2217 the command is on the channel. Affected file silcd/command.c.
2219 * Fixed silc_client_get_clients_local to return the clients
2220 count correctly. It could return wrong value. Affected file
2221 lib/silcclient/idlist.c.
2223 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2226 types. The assembler optimizations seemed not to like 64-bit
2227 data types. The assmebler optimizations thus are now enabled
2228 also for BSD systems as opposed to only enable them for Linux.
2230 * Do not check for threads at all on BSD systems. Affected
2231 file configure.in.pre.
2233 * Removed -n and -h options from the Irssi SILC Client since
2234 they are not used in silc.
2236 * Fixed the prime generation to assure that the first digit
2237 of the generated random number is not zero since our conversion
2238 routines does not like number strings that starts with zero
2239 digit. If zero digit is seen the random number is regenerated.
2240 This caused some corrupted RSA keys when the zero first digit
2241 was met. Affected file lib/silcmath/silcprimegen.c.
2243 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Fixed WIN32 configuration in the ./configure script.
2246 Fixed to include xti.h on environments that has it.
2247 Patches by Carsten Ilchmann and andrew.
2249 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Changed the silc_id_create_client_id to be collision
2252 resistant. It is now assured that there cannot be created
2253 two same client ID's. I suspect that some weird bugs in
2254 the server were actually caused by duplicate Client IDs.
2255 Affected file silcd/serverid.[ch]. A router receiving
2256 new ID now also assures and informs the sending server
2257 if the ID caused collision.
2259 * Changed the silc_id_create_channel_id to also assure that
2260 there are no collisions.
2262 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Statement about ignoring the Mutual Authentication flag when
2265 performing rekey with PFS was a bit misleading. It is ignored
2266 if it was set in the initial negotiation, it cannot be even
2267 set in the rekey. Fixed in the ke-auth draft. Started the
2268 new versions of the protocol drafts in the doc/.
2270 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Fixed a bug in silc_client_command_identify_save when saving
2273 new channel information. The channel name was no duplicated
2274 and caused crash on exit. Affected file is
2275 lib/silcclient/command_reply.c.
2277 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Fixed the getkey command handling in the server. Send just
2280 empty OK reply to the sender if the key could not be fetched
2281 (but everything else was ok, like the key just was not available).
2282 Changed the public key parameter to optional in the protocol
2283 specs so that empty OK reply can be sent. Affected file
2286 Added a message to Irssi SILC client to tell to user if the
2287 server did not return a public key.
2289 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Fixed a channel key regeneration bug. It registered new
2292 timeout tasks exponentially until all system resources were
2293 used. Affected file silcd/server.c.
2295 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Added the SILC Document generator to the scripts/silcdoc.
2298 It can be used to generate the Toolkit Reference Manual out
2299 of the source tree. Internally it will also use the RoboDoc
2300 generator now imported in util/robodoc.
2302 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Added couple of return's in rekey protocol if error orccurred
2305 during the protocol. The execution must be terminated.
2306 Affected file silcd/protocol.c. Also, terminate the protocol
2307 always with timeout.
2309 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * The client's Client ID was created initally from the wrong
2312 nickname (it could have been in format nick@host) in the
2313 silc_server_new_client. Affected file silcd/packet_receive.c
2315 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Added some SILC_LOG_ERROR's to various error conditions
2318 if client could not be added to ID cache. Affected files
2319 silcd/packet_receive.c and silcd/server.c.
2321 * When client's sock->user_data is freed, NULL also the
2322 client->router and client->connection pointers. Added check
2323 for these pointers being NULL to various places around the
2324 code. Affected file silcd/server.c.
2326 * Added client->data.registered == TRUE checks to various
2327 places around the code to assure that unregistered client's
2328 are not handled when it is not allowed. Affected file
2331 * Added `bool registered' fields to all
2332 silc_idlist_[server|client]_get_* routines to indicate whether
2333 the fetched client needs to be registered or not. Affected
2334 file silcd/idlist.[ch].
2336 * Add your own entry as registered to the ID cache in the
2337 server. Affected file server.c.
2339 * Fixed a bug in silc_server_new_server. The SilcServer was
2340 set as the new server's context instead of SilcServerEntry.
2341 This naturally caused some weird bugs.
2343 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Do not delete the channel rekey task when adding it
2346 for in silc_server_create_channel_key.
2348 * Changed the silc_server_create_channel_key to return
2349 TRUE or FALSE to indicate the success of the channel key
2352 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Fixed MSVC++ project files and added missing files to
2355 Makefiles under win32/.
2357 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Do not add TCP_NODELAY flag if the operating system
2360 does not have it defined. Affected files are
2361 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2363 * Fixed buffer overflow from Irssi SILC Client. Affected
2364 file irssi/src/fe-common/core/themes.c.
2366 * Fixed double free in client library in the file
2367 lib/silcclient/client.c when disconnecting from server.
2369 * Applied double free patch from cras to Irssi SILC client.
2370 Affected files irssi/src/core/[modules/expandos].c
2372 * Fixed the disconnection handling to Irssi SILC Client.
2373 The application must call silc_client_close_connection
2374 in ops->connect client operation in case of failure of
2375 the connection. Affected file is
2376 irssi/src/silc/core/client_ops.c.
2378 * Do not set sock->protocol to NULL in the function
2379 silc_client_close_connection after executing the protocol's
2380 final callback since the sock might not be valid anymore.
2381 Affected file lib/silcclient/client.c.
2383 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Do not enable SILC_THREADS if the linking with libpthread
2386 did not happen. Affected file configure.in.pre.
2388 * Added notion to protocol specification that server must
2389 verify the sent authentication payload with CMODE when
2390 setting the channel founder key. Implemented it to the
2391 server. Affected file silcd/command.c.
2393 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Added _EXTRA_DIST SILC distribution variable to the
2396 distributions file. It is used to conditionally add extra
2397 files or directories to the specific distribution. Affected
2398 files ./prepare, Makefile.am.pre and distributions.
2400 Removed the `_' from the start of the distribution names.
2403 * Added README.WIN32 for instructions to compile the Toolkit
2406 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Fixed a double free in disconnection in the server. Affected
2409 file is silcd/server.c.
2411 * Fixed the lib/silcske/groups.c to work now also with GMP
2412 MP library. The string conversion did not work when using
2413 specific base and the base is indicated in the string as well.
2415 * Created win32/ directory which now includes MSVC++ specific
2416 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2417 It will appear only in the toolkit distribution
2419 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Changed the key material distribution function in case when
2422 the hash output is too short. The data is now concatenated
2423 a bit differently than it used to. Made the change to the
2424 SKE protocol specification.
2426 * Added better GMP detection to configure.in.pre. A patch
2429 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Fixed a minor bug in SKE that might cause some problem on
2432 some platforms. Affected file lib/silcske/silcske.c.
2434 * Added the cookie checking for initiator in the SKE. It checks
2435 that the responder returns the sent cookie unmodified. The
2436 affected file is lib/silcske/silcske.c. Added new SKE
2437 error type INVALID_COOKIE that can be sent during the
2438 negotiation. Fixed some memory leaks as well.
2440 * Added the "invalid cookie" error message to Irssi SILC client's
2443 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Added `task_max' field to the SilcClientParams to indicate
2446 the maximum tasks the scheduler can handle. If set to zero,
2447 default values are used. Affected file lib/silcclient/silcapi.h.
2449 * Fixed memory leaks in silc_client_close_connection. Affected
2450 file lib/silcclient/client.c.
2452 * Added silc_client_del_client_entry to client library to free
2453 all memory of given client entry. Affected file is
2454 lib/silcclient/idlist.[ch].
2456 * Added new functions silc_client_del_channel and
2457 silc_client_del_server to delete channel and server entries.
2458 Affected file lib/silcclient/[silcapi.h/idlist.c].
2460 * Removed silc_client_del_client_by_id from silcapi.h.
2462 * Fixed the INFO command to return the server's own info
2463 correctly when querying by Server ID. Affected file is
2466 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Removed the non-blocking settings in WIN32 code in the
2469 silc_sock_[read/write] and added SleepEx instead. Affected
2470 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2471 of input data is now checked with FIONREAD and ioctlsocket.
2473 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Call silc_schedule_task_del_by_context in the
2476 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2477 Affected file lib/silccore/silcprotocol.c.
2479 * Call silc_protocol_cancel for active protocols in the
2480 silc_server_close_connection if the funtion
2481 silc_server_free_sock_user_data has not been called.
2482 Affected file silcd/server.c.
2484 * Generic tasks cannot be deleted using the del_by_fd
2485 task deleting function since generic tasks does not match
2486 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2488 * Added a notion to SILCOPER help file that the SILCOPER works
2489 only on router server, not on normal server.
2491 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added for WIN32 support for the new scheduler as well.
2494 Affected file lib/silcutil/win32/silcwin32schedule.c.
2496 * Fixed the SHA1 implementation to work on various platforms.
2498 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2501 API. It is part of the scheduler now. Everything else is
2502 as previously but some functions has changed their names.
2503 Checkout the lib/silcutil/silcschedule.h for the interface.
2504 Updated all applications to use the new interface. Affected
2505 files are lib/silcutil/silcschedule.[ch].
2507 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Found a bug in the SKE implementation. The HASH value,
2510 specified by the protocol, was not computed correctly. The
2511 public key of the responder was not added to the computation
2512 even though it is mandatory. Affected file lib/silcske/silcske.c.
2513 This unfortunately causes incompatibilities with older
2514 clients and servers.
2516 * Added WIN32 specific network init and uninit functions:
2517 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2518 the Winsock2. Affected file lib/silcutil/silcnet.h and
2519 lib/silcutil/win32/silcwin32net.c.
2521 * Set the socket always to nonblocking mode on WIN32 after
2522 reading data or writing data. Affected file is
2523 lib/silcutil/win32/silcwin32sockconn.c.
2525 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Fixed various compilation problems under WIN32. Affected
2528 files lib/silcutil/win32/silcwin32thread.c and
2529 lib/silcutil/win32/silcwin32schedule.c.
2531 * Removed all _internal.h #includes from public header
2532 files. Internal headers must never be included from
2535 Removed also the lib/silcske/payload_internal.h file.
2537 * All include files that may be needed (public and some others
2538 included by the public headers) by application developers are
2539 now copied to the ./includes directory. It does not copy any
2540 internal headers. Affected file Makefile.defines.pre and all
2541 Makefile.am's under lib/ and subdirs.
2543 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Do not change the ~/.silc directory's permissions automatically.
2546 Affected file irssi/src/silc/core/clientutil.c.
2548 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Do not cancel the protocol in silc_server_close_connection
2551 it might cause recursion. Now cancelled in the function
2552 silc_server_free_sock_user_data. Affected file silcd/server.c.
2554 * Fixed the silc_server_remove_clients_by_server to regenerate
2555 the channel keys correctly finally. Added also new function
2556 silc_server_remove_clients_channels to actually do it.
2557 Affected file silcd/server.c.
2559 * Fixed the silc_server_new_channel to not crash by giving
2560 wrong router to the new channel. Affected file is
2561 silcd/packet_receive.c.
2563 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2566 which is given as argument to the silc_client_alloc now.
2567 It can be used to configure the client and set various parameters
2568 that affect the function of the client.
2570 * The USERS command in server did not check whether the channel
2571 is private or secret. Affected file silcd/command.c.
2573 * Added new argument to the USERS command in protocol specification.
2574 The USERS command now can take the channel name as argument
2575 as well. Added support for this in client and server and
2576 updated the protocol specs.
2578 * Completed the GETKEY command in client. It can be now used
2579 to fetch also servers public key not only some clients.
2580 Affected files lib/silcclient/command[_reply].c.
2582 * Added silc_client_get_server to return server entry by the
2583 server name. Affected files lib/silcclient/silcapi.h and
2586 * Redefined the IDENTIFY command in protocol specification to be
2587 more generic. It now can be used to query information about
2588 any entity in the SILC Network, including clients, servers and
2589 channels. The query may be based either the entity's name
2590 or the ID. Added support for this in both client and server.
2592 Affected files silcd/command.c and lib/silcclient/command.c
2593 and command_reply.c.
2595 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2596 the _from_client and _from_server functions. Affected file
2599 * Added silc_client_get_channel_by_id_resolve to the file
2600 lib/silcclient/silcapi.h to resolve channel information by
2601 its ID. Added also silc_client_get_channel_by_id that
2602 does not resolve it from the server.
2604 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Added SilcServerEntry context into the client library
2607 to represent one server. The INFO command now allocates
2608 these to save the resolved server info. For now on the
2609 client library will also keep information about servers,
2610 connected and resolved with INFO.
2612 The INFO command now allocates the SilcServerEntry context
2613 and saves the server info there. The COMMAND_REPLY in
2614 the INFO now returns the parameters to application in
2615 same order as defined in the protocol specification.
2617 The entries are cached in the client->server_cache.
2619 * The INFO command is now issued after received the Client ID
2620 from the server. Affected file lib/silcclient/client.c.
2622 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2623 to the application as the mode changer might be server.
2624 It is guaranteed that NULL is not returned anymore to the
2625 application. Affected file lib/silcclient/client_notify.c.
2627 The ID Type is now also passed to the application so that
2628 it can check whether the returned entry is SilcClientEntry
2631 Added new function silc_client_get_server_by_id to return
2632 the server entry by ID. Affected files are the
2633 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2635 * Do not create the channel in the Irssi SILC Client when issuing
2636 the JOIN command but when received the sucessful JOIN command
2637 reply. Otherwise the channel might get created even though we
2638 could not join it. The Affected file is
2639 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2641 * Fixed a channel joining bug in router. The router must also
2642 check the channel modes, invite and ban lists etc. when serving
2643 the JOIN command sent by normal server. Affected file is
2644 silcd/command.c. The router now resolves the client's
2645 information from the server who sent the JOIN command if it
2646 does not know it, and processes the JOIN command only after
2649 * Changed the SilcCommandCb to take new argument; void *context2.
2650 Affected file lib/silccore/silccommand.h
2652 The second argument in the command callbacks in the server now
2653 includes the SilcServerCommandReplyContext if the command was
2654 called as pending command callback from the command reply.
2655 Otherwise it is NULL. When called as pending the status of the
2656 command reply will be checked and if it was erronous the
2657 error will be sent to the original sender of the command.
2658 This way the client always receives the error messages even
2659 though the server was actually the one who received the error
2660 when it resent the command to router, for example. Affected
2661 files silcd/command[_reply].[ch].
2663 * Fixed sending WHOWAS command's error message to client if
2664 the requested client could not be found. It was missing.
2667 * Changed the CMODE and CUMODE commands reply arguments in the
2668 protocol specification. The Channel ID is now sent in both
2669 of the commands to identify the channel. Implemented this
2670 new feature to the client and server. Affected files
2671 lib/silcclient/command_reply.c and silcd/command.c.
2673 * Made better checks for invite and ban lists in the JOIN
2674 command in server. Affected file silcd/command.c.
2676 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * The server now performs the incoming host IP/DNS lookup
2679 using the silc_socket_host_lookup and thus does not block
2680 the server anymore. Affected file silcd/server.c.
2682 * Completed the multi-thread support for SILC Scheduler in
2683 the lib/silcutil/silcschedule.c.
2685 * Fixed the configure.in.pre to detect the pthread correctly
2688 * Fixed a deadlock in silc_task_queue_wakeup in the file
2689 lib/silcutil/silctask.c.
2691 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Added new function silc_schedule_wakeup that is used in
2694 multi-threaded environment to wakeup the main thread's
2695 schduler. It needs to be used when a thread adds a new task
2696 or removes a task from task queues. After waking up, the
2697 scheduler will detect the task queue changes. If threads
2698 support is not compiled in this function has no effect.
2699 Implemented the wakeup mechanism to both Unix and WIN32
2700 systems. Affected files are lib/silcutil/silcschedule.[ch],
2701 lib/silcutil/unix/silcunixschedule.c and the
2702 lib/silcutil/win32/silcwin32schedule.c.
2704 * Added new function silc_task_queue_wakeup to wakeup the
2705 scheduler by the specified task queue. Affected file
2706 lib/silcutil/silctask.[ch].
2708 * The silc_socket_host_lookup_start now wakes up the scheduler
2709 after adding the timeout task. Affected file is
2710 lib/silcutil/silcsockconn.c.
2712 * The silc_socket_host_lookup is synchronous now if the threads
2713 support is not compiled in. However, the callback is still
2714 called asyncronously through the scheduler, anyway. Affected
2715 file lib/silcutil/silcsockconn.c.
2717 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * Added new function silc_socket_host_lookup to perform
2720 asynchronous IP and FQDN lookups for the socket connection.
2721 Affected files lib/silcutil/silcsockconn.[ch].
2723 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2726 that may or may not compile the mutex support in.
2728 Changed the silc_mutex_alloc interface. It allocates the
2729 mutex now to the sent pointer and returns TRUE or FALSE.
2731 Affected file lib/silcutil/silcmutex.h.
2733 * Wrote the SILC Task Queue interface to support multi-threads.
2734 Affected file lib/silcutil/silctask.[ch].
2736 * Wrote the SILC Scheduler to support multi-threads. Affected
2737 file lib/silcutil/silcschedule.c.
2739 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2742 in lib/silcutil/win32/.
2744 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Defined SILC Mutex API and SILC Thread API and implemented
2747 them for Unix. Affected files are
2748 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2749 lib/silcutil/unix/silcunixmutex.c and
2750 lib/silcutil/unix/silcunixthread.c.
2752 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Fixed the silc_server_remove_clients_by_server's channel
2755 key re-generation. The hash table handling was incorrect
2756 and would not work with many channels. Affected file is
2759 * Fixed some memory leaks around the server code.
2761 * Rewrote the silc_server_get_users_on_channel to support IPv6
2762 based Client ID's. Affected file silcd/server.c.
2764 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2765 specification. However, a separate document must be written
2766 to define the detailed signing procedure and the payload
2767 associated with the flag. Defined the flag to the
2768 lib/silccore/silcchannel.h as well.
2770 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Changed the dynamic tables to static size tables in the
2773 lib/silccrypt/silchmac.c.
2775 * Removed GCC dependencies from the code. A patch by cras.
2777 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Do not show the error "Error receiving packet bla bla"
2780 in server if it really was not an error (-2 means that reading
2781 is pending). Affected file silcd/server.c.
2783 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Fixed a possible crash in silc_server_remove_clients_by_server
2786 in silcd/server.c. Fixed there also some memory leaks.
2788 * Fixed the silc_idlist_replace_client_id. It could replace
2789 wrong key in the hash table. Affected file silcd/idlist.c.
2791 * Do not check whether there are global users on the channel
2792 if the channel->global_users is FALSE. Affected functions
2793 silc_server_remove_from_one_channel and
2794 silc_server_remove_from_channels in silcd/server.c. Also,
2795 do not check if the removed client is local as we can be
2796 sure that global client was not removed from the channel
2797 and checking for global users is not needed.
2799 * The silc_server_remove_clients_by_server now re-generates
2800 the channel keys correctly for those channels that had
2801 clients removed from them. Affected file silcd/server.c.
2803 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Found the reason of random crashes in the server. We weren't
2806 ignoring the SIGPIPE signal (which can be sent in write())
2807 and it crashed the server. Affected file silcd/silcd.c.
2809 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Assure that sock->user_data is not NULL in the function
2812 silc_server_packet_send in silcd/packet_send.c.
2814 * Disconnect the remote connection if it could not be added
2815 to any ID lists in the server. The affected file is
2818 * Check in silc_server_packet_send[_real/dest] that the
2819 socket is not disconnecting and ignore the data if it is.
2820 Affected file silcd/packet_send.c.
2822 * Define inline to __inline on native WIN32 compilation.
2823 Affected file includes/silcwin32.h.
2825 * Added some explicit type casts for inline code since MSVC
2826 require them. Affected files lib/silcutil/silcbuffer.h,
2827 lib/trq/silcdlist.h and lib/trq/silclist.h.
2829 * Print warning in log files from now on if the packet
2830 decryption fails. Affected file silcd/server.c.
2832 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Changed the `say' client operation's interface to accept
2835 new `type' argument to indicate the type of the message sent
2836 by the library. The application may filter the library's
2837 messages according the type. The affected file is the
2838 lib/silcclient/silcapi.h.
2840 * Added two new functions to lib/silcclient/silcapi.h:
2841 silc_client_del_client and silc_client_del_client_by_id.
2842 Affected file lib/silcclient/idlist.c.
2844 * Moved the clientincludes.h from includes/ to silc/ and
2845 serverincludes.h from includes/ to silcd/.
2847 * The modes for the CMODE and CUMODE are now passed as
2848 uint32 for application with COMMAND_REPLY. The affected
2849 file is lib/silcclient/command_reply.c.
2851 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * /WHOIS without arguments shows client's own information.
2854 Affected file lib/silcclient/command.c.
2856 * Changed PING to not accept any arguments. The specs
2857 says that client can ping only the connected server so
2858 requiring an argument is not needed. Affected file is
2859 lib/silcclient/command.c.
2861 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Fixed a fatal bug in private message sending and reception
2864 encryption and decryption when using private message keys.
2865 The implementation was incorrect and did not follow the
2866 specification. It causd that some of the message were
2867 lost since it did not use the sending and receiving keys
2868 as the protocol suggests. This has been fixed and will cause
2869 incompatibilities with older clients when sending private
2870 message encrypted with private message keys. Affected files
2871 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2872 and various other in Irssi SILC Client.
2874 Added `responder' boolean argument to the functions
2875 silc_client_add_private_message_key[_ske] to indicate when
2876 the key is added as responder or initiator of the key
2879 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Removed the silc_ske_check_version function and created
2882 a SilcSKECheckVersion callback. Added also a function
2883 silc_ske_set_callbacks that is now used to set all SKE
2884 callbacks. The callback functions are not given to
2885 the SKE functions anymore, but this function is used to
2888 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2890 * Added `silc_version' argument to the silc_client_alloc
2891 to define the version of the application for the library.
2892 The library will use the version string to compare it
2893 against the remote host's (usually a server) version
2894 string. Affected file lib/silcclient/silcapi.h
2896 * Added the KE protocol context to Key Agreement context
2897 in client library so that we can abort the SKE if it
2898 is in process when we get timeout. Affected file is
2899 lib/silcclient/client_keyagr.c.
2901 * Do not resolve the client ID forever if it returns in the
2902 first time that such client does not exist. This was done
2903 for example with private message. Affected file is
2904 lib/silcclient/client_prvmsg.c.
2906 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Do not add regex.h for WIN32. The affected file
2909 includes/silcincludes.h.
2911 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2912 not work yet 100%. It generates the DLL's automatically
2913 when compiling with --with-win32 under cygwin.
2915 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * lib/contrib/regex.c is not compiled on WIN32.
2919 * Added silc_net_get_socket_opt function to the
2920 lib/silcutil/silcnet.h.
2922 * Added includes/silcwin32.h for WIN32 specific includes
2925 * Do not use ptime structure or any of the posix process
2926 functions on WIN32 in lib/silccrypt/silrng.c.
2928 * Added silc_gettimeofday to provide generic function
2929 for struct timeval on all platforms. Added the function
2930 to lib/silcutil/silcutil.h.
2932 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2935 library as they clearly belong there. As a plus side we
2936 can make the actual socket connection routines platform
2939 Added also new generic function silc_socket_read and
2940 silc_socket_write (that used to be silc_packet_[read/write].
2941 The implementation of these are platform specific.
2943 * Added WIN32 specific routines of silc_socket_[read/write]
2944 to lib/silcutil/win32/silcwin32sockconn.c.
2946 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Added preliminary support for native WIN32 compilation under
2949 cygwin (using the -mno-cygwin option for GCC) to the
2950 ./configure.in.pre. The --with-win32 now prepares the
2951 compilation for native WIN32.
2953 * Rewrote the SILC Scheduler interface in the file
2954 lib/silcutil/silcschedule.h. The scheduler is now context
2955 based and does not have anymore any global static scheduler.
2956 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2957 and created lib/silcutil/win32 directory for WIN32 based
2960 * Added Unix specific network routines to the
2961 lib/silcutil/unix/silcunixnet.c and the old
2962 lib/silcutil/silcnet.c includes now only generic routines.
2964 Added WIN32 specific network routines to the
2965 lib/silcutil/win32/silcwin32net.c.
2967 * Added Unix specific utility functions from the
2968 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2970 * Added WIN32 SILC Scheduler to the file
2971 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2974 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Do not handle JOIN notify in the server if the target client
2977 is not registered (idata->registered == FALSE). The affected
2978 file is silcd/packet_receive.c.
2980 * Update the nickrec->founder in event_cumode in the Irssi SILC
2981 client. Affected file irssi/src/silc/core/silc-channels.c.
2983 * Fixed the CUMODE_CHANGE notify handling in the server when
2984 server and router are announcing their clients on channels.
2985 Now the mode changes are saved and notified correctly. The
2986 affected file is /silcd/packet_receive.c.
2988 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2989 They really did not replace the cache entry in the ID Cache.
2990 Now they do that. Affected file silcd/idlist.c.
2992 * Fixed the KICK notify handling in the Irssi SILC client to
2993 update the channel records so that the kicked client does not
2994 appear to be on the channel. The affected file is
2995 irssi/src/silc/core/silc-channels.c.
2997 * Always update the conn->current_channel when executing command
2998 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3000 * Fixed the KILL notify handling in Irssi SILC client to remove
3001 the killed client on all channels.
3003 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Fixed the silc_parse_command_line to remove extra spaces
3006 from the start and end of the arguments. Affected file is
3007 lib/silcutil/silcutil.c.
3009 * Cancel and free any active protocol in the function
3010 silc_server_close_connection. Affected file silcd/server.c.
3012 * Cancel and free any active protocol in the function
3013 silc_client_close_connction. Affected file is
3014 lib/silcclient/client.c.
3016 * Do not execute the KILL command for clients that are in
3017 history (ie. they are not in the network). Affected file is
3020 * Fixed KILL notify handling, client does not crash anymore.
3021 Affected file irssi/src/silc/core/silc-channels.c.
3023 * Reduced the default packet buffer size from 2048 to 1024 in
3024 lib/silccore/silcpacket.c.
3026 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3027 counter to the SKE context that is incresed when the SKE library
3028 performs async operation outside the library. If the outside
3029 process frees the SKE context and FREED status will be set
3030 and the library will detect after the sync operation that the
3031 libary is freed. The affected files are
3032 lib/silcske/silcske[_status].[ch].
3034 * Resolve the client entry information in the function
3035 silc_client_channel_message to assure that NULL pointer is not
3036 passed as client entry to the application. */
3038 * Fixed the task timeout calculation to assure that there is
3039 never negative timeouts. The affected file is
3040 lib/silcutil/silcschedule.c.
3042 * Fixed the channel user mode notification sending in server.
3043 It was sent point-to-point to the router (or to server by router)
3044 but it needs to be destined to a channel. The routines now
3045 supports sending the channel user mode notifys to the channels
3046 when announcing clients and channels. Affected files are
3047 silcd/server.c and silcd/packet_receive.c.
3049 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3050 It did not actually replace the old channel entry in the cache.
3051 Affected file lib/silcclient/client_notify.c.
3053 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Fixed a possible crash in silc_packet_send_prepare. It now
3056 assures always that there is enough space in the buffer and
3057 at the tail area of the buffer (for MAC).
3059 Fixed the inbound buffer reallocation in silc_packet_read.
3060 It was old code and did not handle the reallocation correctly.
3063 The affected file is lib/silccore/silcpacket.c.
3065 * Fixed buffer overflow in silc_parse_nickname in the file
3066 lib/silcutil/silcutil.c.
3068 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * make install generates new server keys only if there is not
3073 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3076 Added check that if the NOREPLY is set then we will not send
3077 the away message. This avoids infinite loop of away messages
3078 if both clients are away. The affected file is
3079 lib/silcclient/client_prvmsg.c.
3081 * Fixed client crash if /NICK was given without arguments.
3082 Affected file lib/silcclient/command.c.
3084 * Server does not send the invite list in INVITE command back
3085 to the client if the list was not altered. Added this notion
3086 to the protocol spec as well. Affected file silcd/command.c.
3088 Fixed possible crash in INVITE command by checking the
3089 value of silc_server_get_client_route command.
3091 * Fixed the INVITE notify type handling. The arguments are now
3092 taken in correct order and client does not crash. The affected
3093 file is irssi/src/silc/core/silc-channels.c.
3095 Removed the "Inviting xxx to channel" message from the
3096 client library away and let the application handle it.
3097 Affected file lib/silcclient/command.c. Added that message
3098 to Irssi SILC client's message formats.
3100 * Fixed CMODE command crash in client. It now checks the
3101 amount of arguments correctly and does not crash. The affected
3102 file is lib/silcclient/command.c.
3104 * Do not create new channel automatically in silc_channels_join
3105 but check whether the channel by that name already exists.
3106 Affected file irssi/silc/core/silc-channels.c.
3108 * Do not send the SERVER_SIGNOFF to router if the disconnected
3109 entity was the router. Affected file silcd/server.c.
3111 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3112 SILC client as it was missing from there.
3114 Added the handling of the KICK notify to the Irssi SILC client
3115 as it was missing. Added "you have been kicked" message to
3116 Irssi SILC client's message modules formats.
3118 Added the handing of the KILL notify to the Irssi SILC client
3119 as it was missing. Added the kill message module formats
3122 The affected file is irssi/src/silc/core/silc-channels.c.
3124 * The router did not save the channel mode the server announced.
3125 Affected file silcd/packet_receive.c.
3127 * Fixed a possible crash in INFO command in server. If the
3128 server did not provide the server info it crashed. Affected
3129 file silcd/command.c.
3131 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Fixed the GETKEY command in the server to check also the
3134 global list. Otherwise the GETKEY would not work correctly
3135 in normal SILC server. Affected file silcd/command.c.
3137 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Fixed GETKEY crash, it crashed if the command did not succseed.
3141 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3144 is now real and not just an macro interface to GMP.
3146 Removed the entire GMP from the source tree and imported new
3147 NSS MPI library instead. Reason for removing GMP is that it is
3148 extremely large and compiles extremely slow. The NSS MPI
3149 is only a few files and compiles in less than 10 seconds.
3150 The speed is also about the same as GMP. The MPI is imported
3151 to lib/silcmath/mpi.
3153 If the system has GMP installed we will still use the GMP.
3154 If it is not then the NSS MPI will be compiled.
3156 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Merged a long nickname (127 characters long) crash bugfix from
3159 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3161 * Merged a freed memory reference bugfix from Irssi CVS tree.
3162 Affected file irssi/src/core/commands.c.
3164 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Added the server's public key sving and verification to the
3167 server when performing the SKE. This was missing and the
3168 remote server's (or router's) public key was accepted without
3169 checking whether we have it previously or trust it at all.
3170 Affected file silcd/protocol.c.
3172 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Check in the silc_server_timeout_remote if protocol is active
3175 and make sure that the protocol's final callback is called so
3176 that all memory if freed. Affected file silcd/server.c.
3178 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * silc_server_whois_send_reply crashed the server if the nickname
3181 was 127 characters long. Affected file silcd/command.c.
3183 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Added sanity check to the silc_server_new_client. If the hostname
3186 is provided inside username then check that the provided hostname
3187 really is the same as the resolved one. If the hostname was not
3188 resolved then check it from the public key. Affected file is
3189 silcd/packet_receive.c.
3191 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3192 if the server disconnected us and the connection is not valid
3193 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3195 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3196 the library to the lib/silcutil/silcutil.[ch].
3198 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Close log file after open. Affected file
3201 lib/silcutil/silclog.c.
3203 * Check whether sock == NULL in silc_client_send_packet and return
3204 if it is. Affected file lib/silcclient/silcclient.c.
3206 * Check rec->entry == NULL in the Irssi SILC Client before
3207 sending the channel message. Affecte file is
3208 irssi/src/silc/core/silc-servers.c.
3210 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Merged a splitted window bugfix from Irssi CVS tree. The
3213 affected file is irssi/src/fe-text/textbuffer-view.c.
3215 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3216 It did not print nickname.
3218 * Improved the distributions system a bit.
3220 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3223 irssi/src/fe-text/gui-window.c.
3225 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3226 to in-active server. The affected file is
3227 irssi/src/silc/core/client_ops.c.
3229 * Resolve the client in USERS command reply if the entry does
3230 not have username resolved. The affected file is
3231 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3232 command to WHOIS command to really resolve stuff. The USERS
3233 is not used any more in any critical section so WHOIS can
3234 be used even though it might be slower than IDENTIFY.
3236 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3239 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Changed the protocol API a bit more consistent in the
3242 lib/silccore/silcprotocol.[ch].
3244 * Changed the following headers to ROBODoc format:
3246 lib/silccore/silcpayload.h
3247 lib/silccore/silcprotocol.h
3248 lib/silccore/silcsockconn.h
3250 All core library headers are now formatted.
3252 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Fixed a bug in Irssi SILC client; do not show that you are
3255 server/router operator if you really are not. Affected file is
3256 irssi/src/silc/core/client_ops.c.
3258 * Renamed silc_command_free_payload to silc_command_payload_free.
3259 Affected file lib/silccore/silccommand.h
3261 * Added silcmath.h to include the prototoypes of various routines
3262 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3265 * Changed the following headers to ROBODoc format:
3267 lib/silccore/silcchannel.h
3268 lib/silccore/silccommand.h
3269 lib/silccore/silcid.h
3270 lib/silccore/silcidcache.h
3271 lib/silccore/silcmode.h
3272 lib/silccore/silcnotify.h
3273 lib/silccore/silcpacket.h
3274 lib/silcmath/silcmath.h
3276 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Added checking to the server code not to start the server if
3279 ciphers and stuff are not configured properly. Affected files
3280 silcd/serverconfig.[h] and silcd/server.c.
3282 * Changed the layout of the header files of the public interfaces
3283 in the SILC libraries. The new layout supports ROBODoc
3284 documentation tool (and some others) so that it is easy to create
3285 a library reference manual. All the other headers and source
3286 code must still follow the CodingStyle document. Also source
3287 code must not include these ROBODoc stuffs, only the headers.
3288 Furthermore, all public interface headers must now be named
3289 by using `silc' prefix, example: silcapi.h, silccipher.h.
3290 Some files were renamed due to this. All the other headers
3291 must not be used as public interfaces. I will update the
3292 CodingStyle document later. Changed following headers, so far:
3294 lib/silcclient/silcapi.h
3295 lib/silccore/silcauth.h
3296 lib/silccore/silcprivate.h
3297 lib/silccrypt/silcdh.h
3299 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Removed silc_client_packet_send_flush from the client library
3304 as it is not needed. Affected file lib/silcclient/client.[ch].
3306 * Added printing of message of unresolved authentication method
3307 to the Irssi SILC client. Added it to the module formats.
3308 Removed the same message from the client library.
3310 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added new distribution feature, DISTLABEL. Every distribution
3313 can define own preprocessor label that can be used in the
3314 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3315 file distributions, acconfig.h.pre and prepare.
3317 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Added Makefile.defines_int to include the actual definitions
3320 for Makefile.defines.in. Tested the new distribution system,
3321 created distributions and tested installation.
3323 * Added AWAY message printing to the Irssi SILC client. Added
3324 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3326 * Added SCONNECT command to call the SILC's CONNECT command.
3327 Cannot use CONNECT directly since Irssi uses that internally.
3328 Affected file irssi/src/silc/core/silc-servers.c.
3330 Added ACTION local command. It is same as ME command but takes
3331 the channel as mandatory argument.
3333 Rewrote some of the Irssi's help files to suite for SILC
3336 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Added Makefile.defines[.in] that should for now on be included
3339 in all Makefile.am file in the source tree. That file includes
3340 all common compilation definitions for SILC source tree.
3342 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Minor changes to the ./prepare script to change the package
3345 name according the distribution name to the configure.in.
3347 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Created new distribution system. Added file `distributions'
3350 that defines all the distributions that can be created out of
3351 the SILC source tree. The ./prepare script now reads that
3352 file to determine how to prepare the distributions. The
3353 first argument to the ./prepare is the name of the distribution
3354 and second is the version of the distribution. If given
3355 without arguments it creates the default (toolkit) distribution
3356 with the default version (defined in ./prepare).
3358 All Makefile.am files that are subject to the distributions
3359 are now named as Makefile.am.pre. These are ./Makefile.am
3360 and lib/Makefile.am. Others may be changed later.
3362 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added invite list, ban list, some key management and connection
3365 error message printing to module formats in the Irssi SILC client.
3367 * Added new silc_client_set_away_message to set the away message
3368 that is back to the person who sent private message. The
3369 affected file lib/silcclient/silcapi.h and the
3370 lib/silcclient/client_prvmsg.c.
3372 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Fixed the private message sending in the Irssi SILC client,
3375 added local command KEY to the Irssi SILC client.
3377 Added key management and key agreement message formats to the
3378 irssi/src/fe-common/silc/module-formats.[ch].
3380 Added USERS (alias WHO) printing, server/router operator
3381 indication and LIST command printing to the module formats.
3383 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Fixed channel joining notify handling, cumode notify handling
3386 from Irssi SILC client.
3388 * Added SILC specific module-formats to the Irssi SILC client so
3389 that SILC specific message hilighting, colors etc is possible.
3390 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3392 Added channel mode, channel user mode, actions, notices,
3393 whois and whowas printing to the the module-formats.c.
3395 * Fixed a bug in channel deletion in the server. The channel
3396 is not left to the cache even if the channel founder auth mode
3397 is set when there are no users anymore on the channel. Affected
3398 file silcd/server.c.
3400 * The silc_net_localhost now resolves the entire hostname including
3401 the domain name. Affected file lib/silcutil/silcnet.c.
3403 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Changed the ask_passphrase client operation to be ascynchronous.
3406 It has now a completion callback and a context that the
3407 application must call after it has got the passphrase from
3408 the user. Affected files lib/silcclient/silcapi.h,
3409 lib/silcclient/protocol.c, lib/silcclient/command.c and
3412 Added SilcAskPassphrase callback that the application calls
3413 to deliver the passphrase to the library.
3415 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3416 The public key verification and especially a certificate
3417 verification is asynchronous procedure.
3419 Added new SILC_SKE_STATUS_PENDING status to indicate the
3420 request is pending and a callback will be called to finalize
3423 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3424 indicate that remote end did not send its public key (or
3425 certificate), even though we require it. Added check for this
3426 condition in the SKE. This was a security bug, now fixed.
3428 Defined new SilcSKEVerifyCbCompletion callback that is called
3429 when the verification process is completed.
3431 The affected files lib/silcske/silcske_status.h and
3432 lib/silcske/silcske.[ch].
3434 * Changed the verify_public_key client operation to be async
3435 as well. Defined SilcVerifyPublicKey callback that is used to
3436 indicate the success of the public key verification process.
3438 Changed the server and client to use the new async client
3441 * Changed the Irssi SILC client's internal scheduler to be called
3442 twice as many times as it used to be. As a result the client
3443 should be a bit faster now. Affected file is
3444 irssi/src/silc/core/silc-core.c.
3446 * Added support to Irssi SILC client of asynchronous public key
3447 verification and passphrase inquiry. Affected file is
3448 irssi/src/silc/core/silc-core.c.
3450 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Do not say "You have left channel %s" in client library.
3453 Moved it to the application. Affected files are
3454 lib/silcclient/command.c and silc/client_ops.c.
3456 * Fixed silc_client_get_clients. Command context was not
3457 duplicated and was freed memory in the callback. Affected
3458 file lib/silcclient/idlist.c.
3460 * Do not say "you are now talking..." on JOIN command in the
3461 client library. The appliation must handle it.
3463 * Do not say ".. changed topic to" in command reply in the
3464 client libary. The application must handle it.
3466 * Fixed TOPIC command sending in the client library.
3468 * Fixed a memory leak in silc_client_command_free in the file
3469 lib/silcclient/command.c.
3471 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3473 * Imported a modified version of Irssi client to the source tree.
3474 The Irssi will be used to create a new client called
3475 Irssi SILC. Imported to irssi/.
3477 Added silc_core_init_finish function to the Irssi. Affected
3478 file irssi/configure.in.
3480 A lot changes in the Makefile.ams around the irssi tree.
3482 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Do not rehash if the new size is same as the old size of the
3485 hash table, in the silc_hash_table_rehash*. The affected file
3486 lib/silcutil/silchashtable.c.
3488 * Replaced hash_table_del_by_context calls from the server
3489 (when channel->user_list and client->channels) to the
3490 hash_table_del as it is sufficient and faster.
3492 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Added silc_hash_table_list, silc_hash_table_get and the
3495 SilcHashTableList structure to provide an alternative way to
3496 traverse the hash table. The affected files are
3497 lib/silcutil/silchashtable.[ch].
3499 * Changed the server's idlist routines to use the hash table
3500 routines to optimize the code.
3502 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Replaced the client entry's `channel' list and channel entry's
3505 `user_list' list to hash tables for optimized lookup. Changed
3506 the code to use the hash table interface around the code.
3507 Affected file lib/silcd/idlist.[ch].
3509 * Added `auto_rehash' boolean argument to the function
3510 silc_hash_table_alloc to indicate whether the hash table should
3511 auto-rehash when it thinks is appropriate time. It will
3512 increase the hash table size if the there is twice as much
3513 entries in the table than the size of the table, and will
3514 decrease the size if there are twice as less entries than
3515 the size of the table.
3517 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3521 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * silc_idcache_purge_by_context deletes the entry now by context
3524 as it is supposed to do. Affected file lib/silccore/idcache.c.
3526 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3527 client is not anymore valid (WHOWAS givens the info) and not
3528 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3530 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Removed the `data' and `data_len' arguments from the ID Cache
3533 interfaces and added `name' argument. ID Cache does not handle
3534 anymore the binary data only a names associated with given ID.
3536 * When hashing a Client ID with silc_hash_id the entire ID is
3537 not hashed anymore, instead only the hash of the Client ID is
3538 hashed. This way we can access the Client ID from the cache
3539 with Client ID but with the hash of the ID (which is a hash of
3540 the nickname) as well without any difference in performance.
3542 Added also silc_idcache_find_by_id_one_ext to do one on one
3543 searching when we have the actual ID. Added also function
3544 silc_hash_client_id_compare. The affected files are
3545 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3547 * When hashing the name associated with a ID it is always done
3548 in lowercase. This way we can access the cache without worrying
3549 about case-sensitivity, even though, for example nicknames are
3552 * Fixed a bug in server with channel message sending. It put
3553 wrong ID type as destination ID. The affected file
3554 silcd/packet_send.c.
3556 * silc_idcache_del_by_context now deletes from all hash tables
3557 by context. Affected file lib/silccore/idcache.c.
3559 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Changed the client library to use the new ID Cache interface.
3562 Changes around the source tree.
3564 * Added silc_hash_table_rehash_ext to rehash with specific
3565 hash function. Affected file lib/silcutil/silchashtable.[ch].
3567 * Added silc_hash_string_compare to compare two strings in the
3568 hash table. Affected file lib/silcutil/silcutil.[ch].
3570 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Added new function silc_idcache_del_by_context into the
3573 lib/silccore/idcache.[ch].
3575 * Changed the server's ID list routines to use the new ID Cache
3576 interface. Changes around the source tree.
3578 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Added silc_hash_table_del[_by_context]_ext functions in to the
3581 lib/silcutil/silchashtable.[ch].
3583 Removed silc_hash_table_find_all* routines and added new
3584 silc_hash_table_find_foreach to replace them.
3586 Added silc_hash_table_replace_ext function as extended
3587 replacing function. Separated the simple hash table interface
3588 from the extended hash table interface in the file
3589 lib/silcutil/silchashtable.h.
3591 * Fixed minor bugs and changed it to use some of the new
3592 hash table functions in lib/silccore/idcache.c
3594 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Added new function silc_hash_table_find_all to return all keys
3597 in the hash table by the specified key. As the hash table is
3598 collision resistant it also makes it possible to have several
3599 duplicate keys in the hash table. This function may be used to
3600 find all of the keys from the hash.
3602 Added user_context arguments to the SilcHashFunction,
3603 SilcHashCompare and SilcHashDestructor to deliver user specified
3606 Added new fuctions silc_hash_table_find[_all]_ext to do
3607 extended lookup with specified hash and compare functions and
3608 specified user contexts.
3610 Added new function silc_hash_table_add_ext to add the key
3611 with specified hash function and user context.
3613 Added new function silc_hash_table_foreach to traverse all
3614 entrys in the hash table. Added SilcHashForeach callback
3617 Added new function silc_hash_table_del_by_context to delete
3618 the entry only if the context associated with the key matches.
3620 Affected files are lib/silcutil/silchashtable.[ch].
3622 * Removed silc_hash_[server/client/channel]_id and added just
3623 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3624 silc_hash_id_compare to compare two ID's using as the hash table
3625 comparison function. Added also silc_hash_data to hash
3626 binary data and silc_hash_data_compare to compare it.
3628 * Removed silc_idlist_find_client_by_hash as it is not needed
3629 anymore. Affected file silcd/idlist.[ch].
3631 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3632 to use internally the SilcHashTable. The new ID Cache is a lot
3633 faster than the old one. Some of the ID Cache interface was also
3634 rewritten and obsolete and stupid functions were removed.
3636 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added entry_count field to the SilcHashTable to keep the number
3639 of the entries in the table. Implemented the function
3640 silc_hash_table_rehash. Added new function
3641 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3643 Fixed a minor bug in silc_hash_table_free.
3645 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3646 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3647 into the lib/silcutil/silcutil.[ch].
3649 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Implemented a collision resistant hash table into the
3652 lib/silcutil/silchashtable[ch]. See the header and the source
3653 for the SilcHashTable API.
3655 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Merged dotconf version 1.0.2 into lib/dotconf.
3659 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Do not compile anything in lib/silcsim/* if the SIM support
3662 is not enabled. The tree should now compile without problems
3665 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Compiled the SILC under cygwin. Compiled and tested briefly
3668 without problems. More tests needed. The SIMs didn't compile
3671 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3673 * Fixed possible crash in silc_get_username in the
3674 lib/silcutil/silcutil.c.
3676 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Fixed a va_arg in silc/client_ops.c.
3680 * Oops, RC5 routines were named AES and caused some problems
3681 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3683 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Added new SilcIDIP structure into the lib/silccore/id.h and
3686 replaced the old `ip' fields from all SILC ID's to that type.
3687 This is a step towards IPv6 support.
3689 The silc_id_get_len takes now the ID as an extra argument.
3690 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3691 both IPv4 and IPv6 based ID's.
3693 The affected files are lib/silccore/id.[ch] and other files
3694 around the tree using these routines.
3696 * Removed the ID length arguments in server from various
3697 silc_server_send_notify_* routines -> they are not needed
3700 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Fixed memory leak in silc_encode_pem_file in the file
3703 lib/silcutil/silcutil.c.
3705 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Check minor version as well in the SKE. Affected files are
3708 silcd/protocol.c and lib/silcclient/protocol.c.
3710 * Added --identifier option to the server so that an identifier
3711 can be when creating the public key for the server. Affected
3712 file is silcd/silcd.c.
3714 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3715 lib/silccrypt/silcpkcs.c.
3717 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Register default ciphers and stuff when using -C option with
3720 the server. Affected file sildc/silcd.c.
3722 * Put back the servers public key filename format, it is better
3723 than the new one. For now, the client keys are saved with the
3724 new filename format. The affected file silc/client_ops.c.
3726 * Implemented the Cipher API for the rest of the ciphers that
3727 did not implement it or implemented it the wrong way.
3729 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Register default ciphers and stuff when using the -S option
3732 in the client. Affected file silc/silc.c. Same also when
3733 creating new key pair with -C option.
3735 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Fixed the silc_verify_public_key client operation function to
3738 save the public keys differently. The fingerprint is now
3739 used as filename and not the hostname. This way also the
3740 client keys are saved uniquely and not with hostnames. The
3741 affected file is silc/client_ops.c.
3743 * Trimmed the silc_hash_fingerprint function to remove extra
3744 whitespaces from the end of the fingerprint. The affected
3745 file is lib/silccrypt/silchash.c.
3749 * Added silc_cipher_register_default function to register all
3750 default ciphers. It can be used when configuration files
3751 does not exist and the application does not want any specific
3752 ciphers in any specific order.
3754 The SilcDList is now used as silc_cipher_list dynamically
3755 allocated cipher list. Removed the static list all together
3756 and now all ciphers must be allocated to the dynamic list.
3757 The silc_cipher_alloc routine was changed to check only the
3760 All silc_cipher_* routines that used to return int returns
3763 The affected files lib/silccrypt/silccrypt.[ch].
3765 * The same thing was done to silc_hash_* as for silc_cipher_*
3766 routines. Affected files lib/silccrypt/silchash.[ch].
3768 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3769 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3770 Added also silc_pkcs_[un]register[_default] functions.
3771 Removed the data_context from the PKCS API.
3773 * Added silc_hmac_register_default function to register default
3774 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3775 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3776 to unregister all hmacs at once.
3778 * Register the default ciphers, hash functions, PKCSs and HMACs
3779 if client's configuration file does not exist. The affected
3782 * The client did not load the hash functions from the SIM
3783 modules at all. Added support for this. Affected file is
3784 silc/clientconfig.c.
3786 * When decoding public key with silc_pkcs_public_key_decode, check
3787 the supported algorithm only if PKCS are registered. Affected
3788 file lib/silccrypt/silcpkcs.c. The same was done with the
3789 silc_pkcs_private_key_decode.
3791 * Fixed the SILC List routines to keep the list always in order.
3792 It used to change the list's order when traversing the list but
3793 not it preserves the order. Affected file lib/trq/silclist.h.
3795 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added the client library to use the SilcSocketConnection's
3798 reference counter (by silc_socket_dup) to prevent the bug that
3799 the socket object may be freed underneath async operation.
3801 * The name resolv library checking fixes in the configure.in.pre.
3804 * Created new version of the protocol drafts for future
3805 development. The -03 drafts are the ones that will be changed
3806 in the trunk now and the -02 will remain as they are.
3808 * Send list of CUMODE notifys to the router when announcing
3809 the channel users to the router. Affected file silcd/server.c.
3810 If the router receiving channel founder CUMODE for a channel
3811 that already has channel founder it will send CUMODE notify
3812 to the sender to remove the channel founder rights from the
3813 announced client. Affected file silcd/packet_receive.c.
3815 * The CUMODE notify may now use Server ID as well as the entity
3816 who changes the mode. Updated protocool specs.
3818 * Updated INSTALL and README files.
3820 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * New web pages in the http://silc.pspt.fi. The pages was
3827 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Implemented the [DenyConnectin] config section in the server.
3830 Added silc_server_config_denied_conn to check whether incoming
3831 connection is denied. Affected file silcd/serverconfig.[ch].
3833 * Do not check the ports when checking the incoming configuration
3834 data if the port is 0, meaning any. Affected file is
3835 silcd/serverconfig.c.
3837 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Fixed buffer overflow in silc_string_compare in the file
3840 lib/silcutil/silcutil.c.
3842 * Fixed double free in silc_server_command_leave in the file
3845 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed the version checking in the server. Affected file is
3850 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Fixed the configuration data fetching when accepting new
3853 connections in the server. Affected file silcd/server.c.
3855 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added `sender_entry' argument to the function
3858 silc_server_packet_relay_to_channel so that we can check
3859 whether some destination actually belongs to the same route
3860 the sender belongs (ie, we must not resend the packet to the
3861 sender). Affected file silcd/packet_send.[ch].
3863 * Added `servername' field to the SilcClientEntry in the server
3864 to hold the name of the server where client is from. Affected
3865 file is silcd/idlist.h.
3867 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Moved the channel message encrypting in the router betwen
3870 router connections from silc_server_channel_message to the
3871 silc_server_packet_relay_to_channel since we want to check
3872 whether we have anybody channel before encrypting anything.
3873 Affected files silcd/packet_[receive/send].c.
3875 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Fixed the [AdminConnection] server config section to support
3878 multiple entries. Affected file silcd/serverconfig.c.
3880 * Added support into the server to check the validity of the
3881 incoming connection before executing any KE or authentication
3884 * The connection configuration is now saved to the KE and
3885 connection auth protocol contexts and not fetched anymore in
3886 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3888 * The local hosts listenning address and port is also resolved
3889 now when starting the server. We want to have the socket object
3890 to include the real address and port for the listener. Added
3891 new function silc_net_check_local_by_sock into the files
3892 lib/silcutil/silcnet.[ch].
3894 * Fixed a broadcast bug in server -> do not broadcast if we
3897 * Fixed a routing bug. Do not route broadcast packets ever.
3898 Broadcast packets must be processed always and not routed since
3899 they may be destined to some other host than yourself and thus
3900 would get routed without no good reason. Affected file is
3903 * Added function silc_server_config_is_primary_route to check
3904 whether primary router connection has been configured (a router
3905 configuration that we are initiating). If there is not, we
3906 will assume that there is only two routers in the SILC network
3907 and we will use the incoming router connection as our primary
3908 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3910 * Changed the order of the broadcasting. Broadcast _after_ the
3911 packet has been processed not before. Affected file is
3914 * Fixed a [ClientConnection] parsing bug. The port was never
3915 parsed correctly thus resulting to port 0. Affected file
3916 silcd/serverconfig.c.
3918 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3919 argument and did not set the broadcast packet flag. Affected
3920 file silcd/packet_send.c. Fixed same bug in the function
3921 silc_server_send_notify as well.
3923 * If we receive NEW_ID packet for our own ID in the server, ignore
3926 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Removed the nickname from the Private Message Payload.
3931 Updated the code and the protocol specs.
3933 * Updated protocol specs for submitting to the IETF.
3935 * Tweaked the Random Number Generator a bit. Affected file
3936 lib/silccrypt/silcrng.c. Exported a new function
3937 silc_rng_[global]_add_noise which can be used to add more
3940 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Do not parse packets with different timeout when protocol
3943 is active -> may cause problem with rekey. Affected file
3946 * When server receives signoff notify it must not create
3947 new channel key if the client is on any channels since the
3948 sender of the signoff notify will create it.
3950 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Added printing of error messages during SKE protocol from the
3953 failure packet sent by server during SKE. Affected file
3956 * Removed the client's failure_callback handling with timeout
3957 and handle it immediately when received.
3959 * The SKE library returned wrong type in SUCCESS and FAILURE
3960 packets. They must be 32 bit MSB not 16 bit MSB.
3962 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Ok, rewrote the logic of the re-key and now it seems to work.
3965 I tested it on high traffic with frequent re-keys without
3966 problems. Added hmac_receive (and renamed hmac to hmac_send)
3967 in SilcClientConnection in lib/silcclient/client.h and
3968 in SilcIDListData in silcd/idlist.h. Also, removed the
3969 SilcPacketParserContext's cipher and hmac fields as they are
3970 not needed anymore and actually caused some problems when
3971 the ciphers and hmac's changed underneath the packet parser.
3973 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * If re-key protocol is active then process the incoming packets
3976 synchronously since we must assure that icoming packets encrypted
3977 with the old key is processed before the new keys is set to
3978 use. This is true other packets than for REKEY packets.
3979 Affected file silcd/server.c. The same was done to client library
3980 as well, affected file lib/silcclient/client.c.
3982 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Fixed bug in client and server to accept the force send if
3985 the packet is send from silc_[server/client]_packet_process
3986 function. Otherwise the packets are never delivered, oops.
3988 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Disable force sending of packets when REKEY protocol is active.
3991 We must assure that no packet is sent directly when rekey is
3992 performed. All packets must be sent through packet queue.
3993 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3994 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3995 function is silc_[server/client]_packet_send_real to check
3998 * Replaced the SIM paths from example config files to
3999 /usr/local/modules. Also, make install creates now
4000 /usr/local/silc/logs directory to hold all the SILC server
4003 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Made the configure.in.pre work on Solaris. Patch by salo.
4007 * Made all ciphers compatible with non-x86 machines. Defined
4008 CBC mode macros into lib/silccrypt/ciphers_def.h.
4010 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Fixed the make install.
4014 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * When MAC computation fails the silc_packet_decrypt returned 0
4017 even though it was supposed to return -1. Fixed this. The
4018 affected file is lib/silccore/silcpacket.c.
4020 * Do not replace the config files in /etc/silc (in make install)
4021 if they already exist. Affected file ./Makefile.am.
4023 * Do not send re-key packets immediately but through packet queue.
4024 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4026 * Changed silc_net_check_host_by_sock to return FALSE if the
4027 IP/DNS could not be resolved. Though, it returns the IP address
4028 now even if it could not resolve it (but returns also FALSE).
4029 Affected file lib/silcutil/silcnet.[ch].
4031 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Added silc_pkcs_decode_identifier to decode the public key's
4034 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4035 Added also silc_pkcs_free_identifier. Added also new context
4036 SilcPublicKeyIdentifier.
4038 * Added -S option to the silc client. It is used to dump the
4039 contents of the specified public key file.
4041 * Changed the PKCS api to return the public key length when
4042 setting the public key.
4044 * Fixed a fatal bug in the public and private key file loading.
4045 Affected file lib/silccrypt/silcpkcs.c.
4047 * Execute the packet parsing for client with zero (0) timeout
4048 if the protocol is active. Affected file silcd/server.c.
4050 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Made the key generation options to the silcd program. Added
4053 -C option, equivalent to client's option.
4055 * Added new [ServerKeys] config section to the server. It
4056 configures the server's public and private key.
4058 * Defined generic Public Key Payload into the protocol
4059 specification to send specific type of public keys and
4062 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4063 public key or certificate.
4065 * Implemented the GETKEY command to the server and to the
4066 client library and on user interface.
4068 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Made preliminary `make install' work.
4072 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added SilcServerRekey context into silcd/idlist.h.
4076 * Added the PFS support as defined in the specification to the
4077 SKE protocol. Affected files lib/silcske/*.c.
4079 * Added `ske_group' field to the SilcServerRekey context to hold
4080 the number of the SKE group that is used with PFS in re-key.
4081 Affected file silcd/idlist.h.
4083 * Added PFS re-key support to the server. Affected file is
4086 * Added silc_protocol_cancel to cancel execution of the next
4087 state of the protocol. Affected file is
4088 lib/silccore/silcprotocol.[ch].
4090 * Added the re-key support with and without PFS to the client
4091 library. Re-key is performed once in an hour, by default.
4093 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4094 Added silc_client_rekey_callback and silc_client_rekey_final.
4095 Affected files are lib/silcclient/protocol.[ch] and
4096 lib/silcclient/client.[ch].
4098 * Removed the `hmac_key' and `hmac_key_len' fields from the
4099 SilcClientConnection structure; not needed. Affected file is
4100 lib/silcclient/client.h.
4104 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Do not ask whether user wants to use the negotiated private key
4107 for private messages, just use it. Affected file is
4108 silc/local_command.c.
4110 * Added `send_enc_key' and `enc_key_len' fields to the
4111 SilcIDListData structure since they are needed in the re-key
4112 phase. Affected file is silcd/idlist.[ch].
4114 * Implemented the simple re-key protocol into the server.
4115 Affected files silcd/server.c and silcd/protocol.[ch]. The
4116 re-key will be performed once in an hour, by default.
4118 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4119 Added silc_server_rekey, silc_server_rekey_callback and
4120 silc_server_rekey_final.
4122 * Removed Tunneled flag from the protocol. Updated the code
4123 and the specifications.
4125 * Adde `pfs' field to the SilcIDListData to indicate whether
4126 the PFS is to be performed in the re-key. Affected file is
4129 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4132 int64 of at least the xintXX size. If void * is less that 4
4133 bytes uint32 * will be used. Defined bool as boolean.
4135 * Changed _ALL_ unsigned long and unsigned int to uint32,
4136 unsgined short to uint16 in the source tree.
4138 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4139 not handle clients that has entry->data.registered == FALSE.
4140 They are not in the network anymore. Affected file is
4143 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Implemented the sending of the SERVER_SIGNOFF notify in the
4146 server. Affected file is silcd/server.c.
4148 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4149 Added also silc_notify_payload_encode_args into the
4150 lib/silccore/silcnotify.[ch].
4152 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4153 Affected file silcd/packet_receive.c.
4155 * Implemented the SERVER_SIGNOFF notify handling in the client
4156 library. Affected file lib/silcclient/client_notify.c. Also,
4157 implemnted the printing of the SERVER_SIGNOFF info to the
4158 application. Affected file silc/client_ops.c.
4160 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4161 if the deleting was successful. Affected file silcd/idlist.[ch].
4163 * Added support for public key authentication in the connection
4164 authentication protocol in the client library. Affected file
4165 lib/silcclient/protocol.c.
4167 * Changed the server's silc_idlist_get_clients_by_* interface
4168 to support already allocated array so that new entries may be
4169 added to pre-allocated array. Affected file silcd/idlist.[ch].
4170 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4171 and command replies.
4173 * All command reply functions in the server now calls the
4174 pending command callback even if error occured. This way the
4175 error will be delivered to the client as well. Affected files
4176 silcd/command.c and silcd/command_reply.c.
4178 * Fixed INFO command to return local server's info if no server
4179 was provided. Affected file lib/silcclient/command.c.
4181 * Removed RESTART command for good. Updated the code and the
4184 * Rewrote parts of the task system. It is a bit simpler now.
4185 Removed unsued task priorities. The affected files are
4186 lib/silcutil/silctask.[ch].
4188 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Moved the USERS printing from the library to the application.
4191 Affected files lib/silcclient/command.c and silc/client_ops.c.
4193 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Added channel key re-key support. The re-key is perfomed
4198 only by the router and is done once in an hour. Added `rekey'
4199 field to the SilcChannelEntry in the server. Affected files
4200 silcd/server.c and silcd/idlist.h.
4202 * Added silc_task_unregister_by_context into the file
4203 lib/silcutil/silctask.[ch].
4205 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added SILC_UMODE_GONE mode to indicate when the client is not
4208 present in the SILC network. Added also support to the local
4209 command AWAY that will set this mode. Added support of showing
4210 "xxx is gone" in WHOIS command. The USERS command shows the
4211 gone status as well.
4213 * Fixed setting server and router operator privileges in the
4214 server's UMODE command. Affected file silcd/command.c.
4216 * Merged the SKE KE1 and KE2 payloads into one payload. The
4217 new KE payload is equivalent to the old KE2 payload.
4219 Cleaned up the SKE Start Payload parsing. It now uses the
4220 simple buffer unformatting to do the parsing. A lot faster
4223 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4224 to the SKE that is used to indicate whether both of the SKE
4225 parties should perform authentication. By default only the
4226 responder performs authentication. By setting this flag also
4227 the initiator must do authentication. By default it is unset
4228 since in normal SKE case, client to server connection, only
4229 the responder should do authentication. When doing SKE between
4230 two clients both should perform authentication. Updated the
4231 code and the protocol specs.
4233 * A little fix to IDENTIFY command in the server. Search the
4234 client first by hash not nickname. Affected file is
4237 * Fixed the silc_client_close_connection to support closing
4238 the client to client connections wihtout deleting too much
4239 data. Affected file lib/silcclient/client.c.
4241 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4242 are received if protocol used to be active but is not anymore
4243 the application would crash due to NULL pointer dereference.
4244 Affected files silcd/server.c and lib/silcclient/client.c.
4246 * Added `hash' field to the SilcClientConnection to include
4247 the hash function negotiated in the SKE protocol.
4249 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4250 to set the channel founder authentication data. A client can
4251 claim the founder rights later by providing the authentication
4252 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4253 This way the channel founder can regain the channel founder
4254 privileges even it is left the channel. This works only on
4255 local server and the client must be connected to the same
4256 server to be able to regain the founder rights. Updated the
4257 protocol specs accordingly.
4259 Added support to the CMODE command in the client to set the
4260 founder auth data. Read the README to see how to set it.
4262 Added support to the CUMODE command to claim the founder
4263 rights. Read the README to see how to do it.
4265 Added support for the founder authentication to the Channel
4266 Entry in the server. Affected file silcd/idlist.h.
4268 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4269 server's CMODE command. Affected file silcd/command.c.
4271 * Added the following new functions into lib/silccore/silcauth.[ch]:
4272 silc_auth_get_method and silc_auth_get_data.
4274 * The server now saves the remote hosts public key to the
4275 SilcIDListData pointer. Affected file silcd/protocol.c.
4277 * The normal server now does not remove the channel entry from
4278 the cache if the founder authentication data is set. It used
4279 to remove it if the founder was the last one on the channel on
4280 the server and left the channel. The auth data is saved and
4281 if the channel is re-joined later the old entry is used with
4282 the old auth data. Affected files silcd/command_reply.c and
4285 * Removed the `pkcs' field from the SilcIDListData structure
4286 in the server; it is not used. Affected file silcd/idlist.h.
4288 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Fixed packet processing on slow links. Partial packets were
4291 never re-processed because the incoming data buffer was cleared
4292 by the application. Application must not directly clear the
4293 sock->inbuf, the packet processing routines handle it. Fixed
4294 this in client library and in server.
4296 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Fixed the WHOIS and IDENTIFY send reply function to really
4299 check whether to send list or just one entry. Affected file
4302 * Cleaned up the LEAVE command's channel key distribution. The
4303 affected file silcd/command.c.
4305 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4306 can enforce the channel mode as well. In that case the ID
4307 includes the ID of the server. The code now enforces the
4308 mode change if the router have different mode than the server.
4310 * The notify client operation with CMODE_CHANGE notify can now
4311 return NULL client_entry pointer if the CMODE was not changed
4312 by client. Application must check for this.
4314 * Added <Server ID> argument to INFO command to support server
4315 info fetching by Server ID.
4317 * Added silc_server_announce_get_channel_users to get assembled
4318 packets of channel users of the specified channel. Affected
4319 file silcd/server.[ch].
4321 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4322 was freed underneath the ID Cache.
4324 * Re-announce clients when the server received CHANNEL_CHANGE
4325 notify from the router. Affected file silcd/packet_send.c.
4327 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4330 crashed since it did not handle the fact that there is no cipher
4331 called "3" and didn't check the error condition. Now fixed.
4333 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4334 flag. It can be used to send message requests.
4336 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Implemented the RESTART command in the client.
4340 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4341 notice type messages. Added notice printing to the user
4344 * The channel keys are not re-generated if the channel's mode
4345 is PRIVKEY, ie private key on the channel exists. Affected
4346 files silcd/server.c and silcd/command.c.
4348 * Fixed a little bug in channel message delivery when channel
4349 private keys are set in the server. Affected file is
4350 silcd/packet_send.c.
4352 * Changed the setting on channel->on_channel = TRUE from the
4353 silc_client_save_channel_key to the JOIN command reply. The
4354 key payload is not received if the private channel key is set.
4355 Affected file lib/silcclient/command_reply.c and the
4356 lib/silcclient/client_channel.c.
4358 * When the CMODE_CHANGE notify is sent and the channel private
4359 key mode is removed the channel key must be re-generated in
4360 other cells as well. Added this support for the router in the
4361 silcd/packet_receive.c.
4363 * Added new local command NOTICE to send notice message on
4364 channel. Affected file silc/local_command.[ch].
4366 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added new local command ME to the client. It is used to send
4369 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4370 some action. Affected file silc/local_command.[ch].
4372 * Changed channel_message and private_message client operations
4373 to deliver the message flags to the application. Added also
4374 the `flags' arguments to the silc_client_send_channel_message
4375 and silc_client_send_private_message functions. Affected file
4378 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Redefined the Private Message Payload to support private message
4381 keys and to support the new private message flags. Updated
4382 the protocol specs. Flags makes it possible to have for example
4383 CTCP style messages.
4385 * Added new type SilcPrivateMessagePayload and defined an API
4386 for it in the lib/silcclient/silcprivate.[ch].
4388 * Tested private message private keys successfully. Tested the
4389 private message key set, unset and list commands with the new
4392 * Redefined the Channel Message Payload to include the channel
4393 message flags (equal with private message flags) to support
4394 for example CTCP style messages.
4396 * Defined some of the message (for channel and private message)
4397 flags. Updated the protocol specs and added the flags to the
4398 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4400 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added SilcKeyAgreementStatus type to the key agreement routines
4403 to indicate the current status and error if one occured.
4404 The status types are defined in the lib/silcclient/silcapi.h.
4406 * Added new local command KEY that is used to set and unset private
4407 keys for channels, set and unset private keys for private messages
4408 with remote clients and to send key agreement requests and
4409 negotiate the key agreement protocol with remote client. The
4410 key agreement is supported only to negotiate private message keys,
4411 it currently cannot be used to negotiate private keys for channels,
4412 as it is not convenient for that purpose.
4414 * Fixed a minor pending callback setting bug in the function
4415 silc_client_get_client_by_id_resolve, now the function works.
4416 Affected file lib/silcclient/idlist.c.
4418 * Added function silc_net_get_local_port to get local bound
4419 port by socket. Added to lib/silcutil/silcnet.[ch].
4421 * Added `sockets' and `sockets_count' fields to the SilcClient
4422 object. They hold the sockets of the listenning sockets in
4423 the client. Listenning sockets may be for example the key
4424 agreement server. Affected file lib/silcclient/client.[ch].
4425 Added functions the silc_client_add_socket and the
4426 silc_client_del_socket. They are exported to the application
4429 * Added ~./silc/clientkeys to support other client's public keys.
4431 * Renamed verify_server_key client operation to verify_public_key
4432 and added one argument to indicate the type of the connection
4433 (server, client etc.).
4435 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Added silc_server_connection_auth_request to handle the
4438 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4439 silcd/packet_receive.[ch].
4441 * Added silc_server_send_connection_auth_request into the
4442 silcd/packet_send.c to send the connection auth request packet.
4444 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4447 * Fixed the public key authentication in responder side in the
4448 server. The `auth_data' pointer includes the SilcPublicKey
4449 not the path to the public key. Affected file silcd/protocol.c.
4451 * Implemented the public key authentication in the initiator side
4452 in the server. Affected file silcd/protocol.c.
4454 * Removed the [RedirectClient] config section from the server
4455 configuration. Is not needed and I don't want to implement it.
4457 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Cleaned up the CMODE command in the server. It now works
4460 correctly and supports all the modes defined in the protocol.
4461 Affected file is silcd/command.c.
4463 * Added `hmac_name' field to the SilcChannelEntry in the server
4464 to hold the default HMAC of the channel. It can be set when
4465 creating the channel (with JOIN command). Affected files
4468 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4469 type to indicate the change of the current cipher and hmac
4470 on the channel. Client can safely ignore the <cipher> argument
4471 (if it chooses to do so) since the CHANNEL_KEY packet will
4472 force the channel key change anyway. The <hmac> argument is
4473 important since the client is responsible of setting the new
4474 HMAC and the hmac key into use.
4476 * Fixed the CMODE command in the client library as well.
4478 * Tested CMODE command in router environment successfully.
4480 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Show the version of the remote client (or server) when connecting
4483 to the server. It is logged to the log file. Affected file
4484 is silcd/protocol.c.
4486 * Fixed the KILLED notify handling in the client library. The
4487 client must be removed from all channels when receiving the
4490 Also, do not remove the client entry when giving the KILL
4491 command but when the KILLED notify is received.
4493 * Removed silc_idlist_find_client_by_nickname from the server.
4494 Not needed anymore. Affected files silcd/idlist.[ch].
4496 * Implemented the CHANNEL_CHANGE notify type handling to the
4497 server. Affected file silcd/server.c.
4501 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Added silc_server_send_notify_invite to send the INVITE
4504 notify between routers.
4506 * Implemented the INVITE command correctly to the server.
4508 * Implemented the INVITE notify type handling in the server.
4510 * Implemented the INVITE command to the client library and on the
4513 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added function silc_server_get_client_resolve to find the
4516 client entry by ID from all ID lists and then resolve it
4517 (using WHOIS) if it cannot be found. Affected file is
4520 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Implemented the BAN command to the client library.
4524 * The JOIN command in the server now checks the invite list
4527 * Changed the silc_command_reply_payload_encode_va and the
4528 silc_command_payload_encode_va to support that if argument is
4529 NULL it ignores and checks the next argument. Affected file
4530 lib/silccore/silccommand.c.
4532 * Added silc_server_send_notify_ban to send the BAN notify
4533 type between routers.
4535 * Chaned the silc_notify_payload_encode to support that if
4536 argument is NULL it ignores and checks the next argument.
4537 Affected file lib/silccore/silcnotify.c.
4539 * Tested ban lists in router environment successfully.
4541 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Implemented BAN command to the server, in silcd/command.[ch].
4545 * Removed the BAN and INVITE_LIST modes from the CMODE command
4548 * Added function silc_string_match to regex match two strings.
4549 Affected files lib/silcutil/silcutil.[ch].
4551 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Redefined parts of the SilcChannelEntry in the server to support
4554 the new ban and invite lists.
4556 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Redefined the INVITE command. The same command can be used to
4559 invite individuals to the channel but also to manage the invite
4560 list of the channel (to add to and remove from the invite list).
4561 Updated the protocol specs.
4563 * Added new command SILC_COMMAND_BAN that can be used to manage
4564 the ban list of the channel. Updated the protocol specs.
4566 * Removed the channel modes: the SILC_CMODE_BAN and the
4567 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4568 in the CMODE command. The equivalent features are now available
4569 using INVITE and BAN commands. Updated the protocol specs.
4571 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4572 in the network about change in the current ban list. The notify
4573 type is not used by the client.
4575 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4576 support the invite lists.
4578 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added new function silc_string_regexify that converts string
4581 including wildcard characters into regex string that can
4582 be used by the GNU regex library. Added into the file
4583 lib/silcutil/silcutil.[ch].
4585 Added silc_string_regex_combine to combine to regex strings
4586 into one so that they can be used as one regex string by
4587 the GNU regex library. Added into the file
4588 lib/silcutil/silcutil.[ch].
4590 Added silc_string_regex_match to match two strings. It returns
4591 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4593 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Imported GNU regex to the soruce tree into lib/contrib.
4596 Fixed some compiler warning from the regex.c.
4598 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Fixed MOTD command in the server to work in router environment.
4602 * Fixed the MOTD command in the client library to support
4603 the server argument in the command.
4605 * Added `nickname_len' argument to the silc_idlist_add_client
4606 in the server, as the `nickname' argument may be binary data
4609 * Added silc_idlist_get_channels to return all channels from
4612 * Implemented LIST command to the server. Affected file is
4615 * Implemented the LIST command to the client library and on the
4618 * Added [<user count>] argument to the LIST command reply.
4619 With private channels the user count is not shown.
4621 * Updated TODO and README.
4623 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * The client entry's data.registered must be TRUE even with
4626 global client entry on global client list. The data.registered
4627 is used to check whether the client is anymore in the network,
4628 for example with WHOWAS command so it must be valid.
4630 * Fixed the WHOWAS command in the server. It now actually works
4631 in router environment. Added function into silcd/command_reply.c
4632 silc_server_command_reply_whowas_save.
4634 * Added silc_idlist_purge function to the silcd/idlist.c
4635 to periodically purge the ID Cache.
4637 * Fixed INFO command in the server. It works now in router
4638 environment. Added <server name> argument to the INFO command
4639 reply. Updated the protocol specs.
4641 * Fixed minor bug in silc_idcache_purge to not purge if the
4642 expire value is zero.
4644 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4645 they were buggy because of the WHOWAS information.
4647 * Fixed local command MSG to handle the async resolving of
4648 the remote client properly. It used to fail the first MSG.
4649 Affected file silc/local_command.c.
4651 * Added `data_len' field to SilcIDCache context.
4653 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Update TODO. Todo in commands in the server.
4657 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4660 used by routers as broadcast packet to inform other routers
4661 about the changed user mode.
4663 Implemented the notify handling in the server. Affected file is
4664 silcd/packet_receive.c. Added the function
4665 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4667 * Added new generic Channel Payload and deprecated the New Channel
4668 Payload. The New Channel Payload is now the generic Channel
4671 * Added new argument `mode' to the silc_server_send_new_channel
4672 as it is required in the Channel Payload now.
4674 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4675 and created a new and real SilChannelPayload to represent the
4676 new generic Channel Payload. Implemented the encode/decode
4677 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4679 * Added silc_server_get_client_channel_list to return the list
4680 of channels the client has joined for WHOIS command reply.
4681 Affected file silcd/server.[ch].
4683 * Implemented the channel list sending in the WHOIS command reply
4684 in server and in the client.
4686 Implemented the channel list displaying on the user interface
4687 as well. Affected file silc/client_ops.c.
4689 * Added silc_channel_payload_parse_list to parse list of Channel
4690 Payloads. It returns SilcDList list of SilcChannelPayloads.
4691 Client for example can use this function to parse the list of
4692 channels it receives in the WHOIS command reply. The caller
4693 must free the list by calling silc_channel_payload_list_free.
4694 Affected files lib/silccore/silcchannel.[ch].
4696 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added one new argument <user mode> to the WHOIS command reply
4699 to return the mode of the user in SILC. Updated the protocol
4702 Implemented it to the server and client.
4704 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Fixed the mode printing on the user interface on joining.
4707 Affected file silc/client_ops.c.
4709 * Implemented the UMODE command and user modes in general to the
4710 client library and to the user interface.
4712 * Implemented the UMODE command to the server.
4714 * The server now sends UNKNOWN_COMMAND error status if client sends
4715 unknown command. Affected file silcd/command.c.
4717 * All server commands now handle the command identifier the right
4718 way when sending the command reply to the client. The client can
4719 use to identify the command replies with the identifier.
4721 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Added silc_server_get_client_route to resolve the route to
4724 the client indicated by the client ID. Affected file is
4727 * Added silc_server_relay_packet as general function to relay
4728 packet to arbitrary destination. This deprecates functions
4729 like _send_private_message_key, _relay_notify etc. Affected
4730 file is silcd/packet_send.[ch].
4732 Removed silc_server_send_key_agreement,
4733 silc_server_send_private_message_key and
4734 silc_server_packet_relay_notify functions from the file
4735 silcd/packet_send.[ch].
4739 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4740 server. Affected file silcd/packet_receive.[ch].
4742 * Implemented the KILL command to the client. Implemented the
4743 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4744 Affected files lib/silcclient/command[_reply].c and
4745 lib/silcclient/client_notify.c. Implemented the KILL notify
4746 printing in the user inteface.
4748 * Fixed a lot silc_parse_nick memory leaks from the client
4749 library in the file lib/silcclient/command.c.
4751 * Changed the silc_server_send_notify_on_channels's `sender'
4752 argument from SilcSocketConnection to SilcClientEntry to
4753 check the sender as entry and not as connection object and not
4754 to send to the client provided as argument. The affected file
4755 is silcd/packet_send.[ch].
4757 * The notify packets that are destined directly to the client used
4758 to not to be processed by the server. Now changed that and the
4759 server processes all notify packets. After relaying the packet
4760 to the client the notify packet is processed in the server.
4762 * The silc_server_free_client_data now checks whether there is
4763 pending outgoing traffic for the client and purges the data to
4764 the network before removing the client entry.
4766 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4769 an client is killed from the SILC Network. Updated the protocol
4772 Added new function silc_server_send_notify_killed to the
4773 silcd/packet_send.[ch].
4775 * Added function silc_server_packet_relay_notify to relay notify
4776 packets that are destined directly to a client. In this case
4777 the server does not process the notify packets but merely relays
4778 it to the client. Affected file silcd/packet_send.[ch].
4780 Added also silc_server_packet_process_relay_notify to check
4781 whereto relay the notify. Affected file is
4782 silcd/packet_receive.[ch].
4784 * Implemented the KILL command to the server.
4788 * Added the backup schema desgined last fall to the protocol
4789 specs for everyone to see. The specification is in the
4790 *-spec-xx.txt draft and the packet type definitions for the
4791 backup routers is in *-pp-xx.txt draft. Thusly, added also
4792 new packet type SILC_PACKET_CELL_ROUTERS.
4794 * A big security problem in the implementation discovered. The
4795 signoff of an client did not cause new channel key generation
4796 which it of course should've done. The channel keys must be
4797 always re-generated when client leaves (or signoffs) the channel.
4798 The silc_server_remove_from_channels funtion now handles
4799 the channel key re-generation.
4801 * Added `sender' argument to the silc_server_send_notify_on_channels
4802 to not to send the client provided as argument. Affected file
4803 silcd/packet_send.[ch].
4805 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Implemented OPER and SILCOPER commands into the server and
4810 * Added silc_auth_verify and silc_auth_verify_data to verify
4811 the authentication directly from the authentication payload.
4812 It supports verifying both passphrase and public key based
4813 authentication. Affected file lib/silccore/silcauth.[ch].
4815 * Added `hash' field to the SilcIDListData structure. It is the
4816 hash negotiated in the SKE protocol. Affected file is
4819 * Slight redesigning of the SilcAuthPayload handling routines.
4820 Do not send SilcPKCS but SilcPublicKey as argument.
4822 * Implemented the public key authentication support to the
4823 serverconfig. The public key is loaded from the provided path
4824 and saved as authentication data to void * pointer. Thus,
4825 changed the unsigned char *auth_data to void *auth_data;
4827 * Fixed SHUTDOWN command to send the reply before the server
4828 is shutdown. :) Affected file silcd/command.c.
4830 * Fixed fatal bug in CONNECT command. The hostname was invalid
4831 memory and server crashed. Affected file silcd/command.c.
4833 * Fixed fatal bug in CLOSE command. The server_entry became
4834 invalid but was referenced later in the command. Affected file
4837 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Fixed fatal bug in failure packet handling. Server ignored
4840 the failure and thus crashed when it came.
4844 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4847 that the command may be executed only once in (about) 2 seconds.
4848 The old SILC_CF_LAG flag is same but allows command bursts up
4849 to five before limiting.
4851 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4852 server code. Various commands now includes the CF_LAG_STRICT
4853 flag to disallow any kind of miss-use of the command.
4855 * Fixed the silc_buffer_unformat to not to allocate any data
4856 if the length of the data is zero. It used to allocate the
4857 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4859 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Changed the format of AdminConnection configuration section
4862 in the server. Added username of the admin to the format.
4863 Affected files silcd/serverconfig.[ch].
4865 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4866 to return admin configuration data by host, username and/or
4869 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Implemented WHOWAS command to the server. Added the functions:
4873 silc_server_command_whowas_parse,
4874 silc_server_command_whowas_send_reply,
4875 silc_server_command_whowas_from_client and
4876 silc_server_command_whowas_from_server
4878 * Added <Client ID> argument to the WHOWAS command reply. Updated
4879 the protocol specs accordingly.
4881 * Implemented WHOWAS command and command_reply to the client
4884 Implemented the WHOWAS printing on the user interface.
4886 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added new argument to the WHOWAS command reply, the real name.
4889 It is an optional argument. Updated the protocol specs.
4891 * Added SilcIDCacheDestructor callback that is registered when
4892 the SilcIDCache is allocated. The callback is called when
4893 an cache entry in the ID Cache expires, or is purged from the
4894 cache. Added into lib/silccore/idcache.[ch].
4896 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4897 to destruct the client entries when the cache entry expires.
4898 Other ID Cache's in server and in the client library ignores
4901 * If the ID Cache entry's `expire' field is zero then the entry
4902 never expires. Added boolean `expire' argument to the
4903 silc_idcache_add function in the lib/silccore/idcache.[ch].
4904 If it is TRUE the default expiry value is used.
4906 * Added silc_server_free_client_data_timeout that is registered
4907 when client disconnects. By default for 5 minutes we preserve
4908 the client entry for history - for WHOWAS command.
4910 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Added support to the server to enforce that commands are not
4913 executed more than once in 2 seconds. If server receives
4914 commands from client more frequently, timeout is registered
4915 to process the commands. Affected file silcd/command.c.
4916 Added new function silc_server_command_process_timeout.
4918 * Changed NICK_NOTIFY handling in client library to check that
4919 if the client's nickname was changed, so there is no need to
4920 resolve anything from the server.
4922 * Removed error printing from the WHOIS and IDENTIFY commands.
4923 If error occurs then it is ignored silently in the client library.
4924 The application, however, may map the received error to
4925 human readable error string. The application currently maps
4926 the NO_SUCH_NICKNAME error to string.
4928 * Made the command status message public to the application. Moved
4929 them from lib/silcclient/command_reply.c to
4930 lib/silcclient/command_reply.h. The application can map the
4931 received command status to the string with the
4932 silc_client_command_status_message function.
4934 * Added check to the server to check that client's ID is same
4935 as the Source ID in the packet the client sent. They must
4938 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Added dist-bzip hook to the Makefile.am to make bzip2
4941 compressed distributions.
4943 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Server now enforces the maximum length for the nickname and
4946 the channel as protocol specification dictates. 128 bytes for
4947 nickname and 256 bytes for channel name.
4949 * Moved the WHOIS printing to the application. The client libary
4950 does not print out the WHOIS information anymore, the application
4951 must do it. Renamed silc_client_command_reply_whois_print to
4952 the silc_client_command_reply_whois_save.
4954 The client's idle time is also sent to the application now, and
4955 the idle is shown on screen.
4957 * Added silc_client_command_reply_identify_save to save the
4958 received IDENTIFY entries.
4960 * Do not check for channel private keys in message sending and
4961 reception if the channel does not have the PRIVKEY mode set.
4962 Affected file lib/silclient/client_channel.c.
4964 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4967 just surfaced after chaning the JOIN procedure.
4969 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added silc_client_get_clients_by_list to get client entries
4972 from Client ID list, that is returned for example by JOIN
4973 and USERS command replies. The application should use this
4974 function for example when JOIN command reply is received to
4975 resolve the clients already on the channel (library does not
4976 do that anymore as USERS command reply is not used in the JOIN
4977 procedure anymore). Affected files lib/silcclient/silcapi.h and
4978 lib/silcclient/idlist.c.
4980 * JOIN command reply and USERS command reply returns now SilcBuffer
4981 pointers instead of unsigned char pointers when returning
4982 the client list and mode list.
4984 * Added <Client ID> argument to the JOIN command reply, mainly
4985 for the server to identify for which client the command was
4986 originally sent. Updated protocol specs accordingly.
4988 * Added SilcDlist private_key pointer to the SilcChannelEntry
4989 in the client to support the channel private keys. Affected
4990 file is lib/silcclient/idlist.h.
4992 * Added SilcChannelPrivateKey argument to the function
4993 silc_client_send_channel_message so that application can choose
4994 to use specific private ke if it wants to. If it is not provided,
4995 the normal channel key is used, unless private keys are set.
4996 In this case the first (key that was added first) is used
4997 as the encryption key.
4999 * Implemented the support for channel private key handling.
5000 Implemented the following functions:
5002 silc_client_add_channel_private_key,
5003 silc_client_del_channel_private_keys,
5004 silc_client_del_channel_private_key,
5005 silc_client_list_channel_private_keys and
5006 silc_client_free_channel_private_keys
5008 Affected file lib/silcclient/client_channel.c.
5010 * Added the support for the private keys in the channel message
5011 sending and encryption and in the message reception and
5012 decryption. Affected funtions are
5013 silc_client_send_channel_message and silc_client_channel_message.
5015 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Added SKE's key verify callback to the client library's
5018 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5020 * Removed the statement that server (or router) must send USERS
5021 command reply when joining to the channel so that the client
5022 knows who are on the channel. Instead, the client list and
5023 client's mode list is now sent in the JOIN command reply to the
5024 client who joined channel. This is better solution.
5026 * Added function silc_server_get_users_on_channel and function
5027 silc_server_save_users_on_channel to the silcd/server.[ch].
5029 * Removed function silc_server_command_send_users from the
5032 * Do not show topic on the client library anymore. The topic is
5033 sent in the command reply notify to the application and the
5034 application must show the topic now.
5036 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added client searching by nickname hash into the IDENTIFY and
5039 WHOIS commands in the server as they were clearly missing from
5040 them. Affected file is silcd/command.c.
5042 * Fixed a bug in private message receiving in the client library.
5043 The remote ID was freed and it wasn't supposed, now it is
5046 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Minor fix to the channel payload; allocate the data area, as it
5049 needs to be of specific length.
5051 * If the key agreement port is zero then the operating
5052 system will define the bound port. Affected files are
5053 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5055 * Added new function silc_channel_payload_decrypt into the file
5056 lib/silccore/silcchannel.[ch].
5058 * Moved the channel message etc, check from silc_packet_decrypt
5059 to applications. The library calls now a generic
5060 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5061 when the packet is either normal or special. This was done to
5062 allow more wide range of checking that was not allowed when
5063 the code was in library. Now applications can do virtually any
5064 checks to the packet and return to the library the decision how
5065 the packet should be processed. Affected files are
5066 lib/silccore/silcpacket.[ch].
5068 Added silc_server_packet_decrypt_check to the server and
5069 silc_client_packet_decrypt_check to the client library.
5071 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5072 to send with specified source and destination information.
5074 * Channel message delivery between routers was broken after the
5075 channel key distribution was fixed earlier. The channel key
5076 was used be to distributed to other routers as well which is not
5077 allowed by the protocol. Now this is fixed and channel keys
5078 really are cell specific and the channel message delivery between
5079 routers comply with the protocol specification.
5081 * Fixed various commands in server to check also the global list
5082 for the channel entry and not just the local list. The affected
5083 file silcd/command.c.
5085 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added assert()s to buffer formatting and unformatting routines
5088 to assert (if --enable-debug) when error occurs. Affected
5089 file: lib/silcutil/silcbuffmt.c.
5091 * Changed to auto-reconnect to check whether the remote host is
5092 router and register the re-connect timeout if it is. It used
5093 to check that whether we are normal server, but router must do
5094 auto-reconnect with another router as well. Affected file
5097 * Removed the [<key len>] option from CMODE command as the cipher
5098 name decides the key length, nowadays. See the defined ciphers
5099 from the protocol specification.
5101 * Added [<hmac>] option to the CMODE command to define the HMAC
5102 for the channel. Added SILC_CMODE_HMAC channel mode.
5104 * Added [<hmac>] option for the JOIN command so that user can
5105 select which HMAC is used to compute the MACs of the channel
5108 * Added Hmac field to the Channel Message Payload. The integrity
5109 of plaintext channel messages are now protected by computing
5110 MAC of the message and attaching the MAC to the payload. The
5111 MAC is encrypted. Now, it is clear that this causes some
5112 overhead to the size of the packet but rationale for this is that
5113 now the receiver can verify whether the channel message decrypted
5114 correctly and also when private keys are set for the channel the
5115 receiver can decrypt the packet with several keys and check from
5116 the MAC which key decrypted the message correctly.
5118 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5119 lib/silccrypt/silccipher.[ch].
5121 * Added silc_hash_len to return the digest length into the
5122 lib/silcrypt/silchash.[ch].
5124 * Rewrote parts of Silc Channel Payload interface in the
5125 lib/silccore/silcchannel.[ch]. The encode function now also
5126 encrypts the packet and parse function decrypts it.
5128 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Fixed a minor formatting bug in the SKE's key material processing.
5131 It actually might have processed the keys wrong way resulting
5134 * Redefined the mandatory HMAC algorithms and added new algorithms.
5135 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5136 and hmac-md5 truncated to 96 bits. The mandatory is now
5137 hmac-sha1-96. Rest are optional (including the one that used
5138 to be mandatory). Rationale for this is that the truncated HMAC
5139 length is sufficient from security point of view and can actually
5140 make the attack against the HMAC harder. Also, the truncated
5141 HMAC causes less overhead to the packets. See the RFC2104 for
5144 * Added new [hmac] configuration section. The SKE used to use
5145 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5146 is of course wrong. The official names that must be proposed in
5147 the SKE are the ones defined in the protocol specification
5148 (hmac-sha1-96 for example). The user can configure any hmac
5149 using any hash function configured in the [hash] section. At
5150 least, the mandatory must be configured.
5152 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5154 * Added HMAC list to the SKE proposal list. It has now both
5155 hash algorithm list and HMAC list. This makes the protocol
5156 incompatible with previous versions. The SKE now seems to work
5157 the way it is supposed to work, for the first time actually.
5159 * Defined plain Hash algorithms to the protocol specification.
5162 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Implemented support for key agreement packets into the server.
5165 Added functions silc_server_key_agreement and
5166 silc_server_send_key_agreement. Other than these functions,
5167 server has nothing to do with this packet.
5169 * Added support for private message key packets into the server.
5170 Added functions silc_server_private_message_key and
5171 silc_server_send_private_message_key.
5175 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5176 called in the protocol's final callback instead in the END
5177 protocol state. This makes a little more sense and in the same
5178 time in client we can use the same protocol routines for normal
5179 key exchange and to key agreement packet handling as well.
5181 * Added to both client's and server's KE protocol context the
5182 SilcSKEKeyMaterial pointer to save the key material. We will
5183 bring the key material to the protocol's final callback by doing
5184 this. The final callback must free the key material.
5186 * Added SKE's packet_send callback into client's KE protocol
5187 context so that the caller can choose what packet sending function
5188 is used. This way we can use different packet sending when
5189 doing normal SKE when doing key agreement packet handling (in
5190 the key agreement packet handling we do not want to encrypt
5193 * Implemented the responder side of the key agreement routines
5194 in the client. The client can now bind to specified port and
5195 accept incoming key negotiation. The key material is passed
5196 to the application after the protocol is over.
5198 * Implemented the processing of incoming Key Agreement packet
5199 in the client. Added function silc_client_key_agreement to
5202 * Implemented the intiator side of the key agreement routines
5203 in the client. The client can now initiate key agreement with
5204 another remote client. The key material is passed to the
5205 application after the protocol is over.
5207 * Created client_keyagr.c to include all the key agreement
5210 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5211 SILC_TASK_CALLBACK except that it is not static.
5213 * Created client_notify.c and moved the Notify packet handling
5214 from the client.[ch] into that file.
5216 * Created client_prvmsg.c and moved all private message and
5217 private message key routines from the client.[ch] into that file.
5219 * Create client_channel.c and moved all channel message and
5220 channel private key routines from the client.[ch] into that file.
5222 * Changed silc_client_get_client_by_id_resolve to resolve with
5223 WHOIS command instead of IDENTIFY command, in the file
5224 lib/silclient/idlist.c.
5226 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Implemented the SKE's responder side to the Client library.
5230 * When FAILURE is received to the protocol do not trust it
5231 blindly. Register a timeout to wait whether the remote closes
5232 the connection as it should do it, only after that process the
5233 actual failure. This was changed to both client and server.
5235 * Added client_internal.h to include some of the structures
5236 there instead of client.h in lib/silcclient/.
5238 * Added function silc_task_unregister_by_callback to unregister
5239 timeouts by the callback function.
5241 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Some "Incomplete WHOIS info" errors has been appearing on the
5244 log files. Took away the entry->userinfo check from WHOIS
5245 reply sending. The entry->userinfo is now " " if client did not
5246 provide one. I thought this was fixed earlier but something
5247 is wrong still. Let's see if the error still appears.
5249 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Fixed a minor bug in the login when the channel key is
5252 re-generated in the server. It used to generate the key in
5253 wrong order and thus caused problems in the channel traffic.
5255 * Fixed a minor bug in channel key distsribution after
5256 KICK command. The key was not sent to the router even though
5259 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Added silc_ske_process_key_material_data as generic routine
5262 to process any key material as the SILC protocol dictates. The
5263 function is used by the actual SKE library but can be used by
5264 applications as well. This relates to the private message keys
5265 and the channel private keys since they must be processed the
5266 same way the normal SILC session keys. The protocol dictates
5267 this. Affected files: lib/silcske/silcske.[ch].
5269 Added also silc_ske_free_key_material to free the
5270 SilcSKEKeyMaterial structure.
5272 * Defined silc_cipher_set_key function to set the key for
5273 cipher without using the object's method function. The affected
5274 files: lib/silccrypt/silccipher.[ch].
5276 * Implemented silc silc_client_add_private_message_key,
5277 silc_client_add_private_message_key_ske,
5278 silc_client_del_private_message_key,
5279 silc_client_list_private_message_keys and
5280 silc_client_free_private_message_keys functions in the
5283 Added functions silc_client_send_private_message_key to send
5284 the Private Message Key payload and silc_client_private_message_key
5285 to handle incoming Private Message Key payload.
5287 * Added Cipher field to the Private Message Key payload to set
5288 the cipher to be used. If ignored, the default cipher defined
5289 in the SILC protocol (aes-256-cbc) is used.
5291 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Removed lib/silcclient/ops.h file.
5295 Redefined parts of the SILC Client Library API. Created new
5296 file silcapi.h that deprecates the ops.h file and defines the
5297 published Client Library API. Defined also private message key
5298 API and channel private key API into the file.
5300 This is the file that the application must include from the
5301 SILC Client Library. Other files need not be included by
5302 the application anymore.
5304 * Added new key_agreement client operation callback and also
5305 defined the Key Agreement library API for the application.
5307 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5310 is used by clients to request key negotiation between another
5311 client in the SILC network. If the negotiation is started it
5312 is performed using the SKE protocol. The result of the
5313 negotiation, the secret key material, can be used for example
5314 as private message key.
5316 Implemented the Key Agreement payload into the files
5317 lib/silccore/silauth.[ch].
5319 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Redefined ciphers for the SILC protocol. Added some new ciphers
5322 and defined the key lengths for the algorithms. Changed the
5323 code accordingly. The default key length is now 256 bits.
5325 * Fixed SKE key distribution function silc_ske_process_key_material
5326 when the key length is more than 128 bits. The default key
5327 length in SILC is now 256 bits.
5329 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5330 to indicate unsupported algorithm.
5332 * Renamed rijndael.c to aes.c and all functions as well.
5334 * Fixed a long standing channel key setting bug in client library.
5335 Weird that it has never surfaced before.
5337 * Fixed bug in channel deletion. If the entire channel is removed
5338 then it must also delete the references of the channel entry
5339 from the client's channel list as the client's channel entry and
5340 the channel's client entry share same memory.
5342 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Implemented CONNECT and SHUTDOWN commands in the client.
5346 * Implemented CLOSE command to the client.
5348 * Added the function silc_idlist_find_server_by_name into the
5349 files silcd/idlist.[ch].
5351 Added the function silc_idlist_find_server_by_conn into the
5352 files silcd/idlist.[ch].
5354 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * DIE command was renamed to SHUTDOWN. Updated the both code
5359 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5360 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5362 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5365 * Added function silc_server_create_connection function to create
5366 connection to remote router. My server implementation actually
5367 does not allow router to connect to normal server (it expects
5368 that normal server always initiates the connection to the router)
5369 so the CONNECT command is only good for connecting to another
5372 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5375 or some other client was kicked from the channel.
5377 Implemented the handling of the notify type to both client
5380 Implemented silc_server_send_notify_kicked to send the KICKED
5381 notify. It is used to send it to the server's primary router.
5383 * Implemented the KICK command into server and client.
5385 * Added `query' argument to the silc_idlist_get_client function
5386 to indicate whether to query the client from server or not if
5389 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5390 to indicate that the client is not channel founder.
5394 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Removed the rng context from SilcPacketContext structure and
5397 changed that the packet routine uses the Global RNG API.
5399 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added support for quit message that client can "leave" on the
5402 channel when it quits the SILC. It is ditributed inside the
5403 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5405 Added silc_server_free_client_data that will take the
5406 signoff message as argument.
5408 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5410 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Updated parts of the protocol specification to keep it up
5415 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5418 payloads in one packet.
5420 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5421 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5422 use now the new List flag.
5424 * Also deprecated the following packet types: REPLACE_ID,
5425 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5427 * Added list support for Notify packet in server.
5429 * Added silc_server_send_notify_channel_change to send the
5430 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5431 the silc_server_send_replace_id.
5433 * Added silc_server_send_notify_nick_change to send the
5434 NICK_CHANGE notify type. Deprecates the function
5435 silc_server_send_replace_id.
5437 * Added silc_server_send_notify_join to send the JOIN notify type.
5438 Deprecates the function silc_server_send_new_channel_user.
5440 * Added silc_server_send_notify_leave to send LEAVE notify type.
5441 Deprecates the function silc_server_send_remove_channel_user.
5443 * Added silc_server_send_notify_cmode and
5444 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5445 types. Deprecates the silc_server_send_set_mode function.
5447 * Added SERVER_SIGNOFF notify type to indicate that server has
5448 quit. This means that all clients on the channel from that
5449 server will drop. This can be also used when netsplit happens.
5451 Deprecated REMOVE_ID packet type since it is not needed anymore
5454 Added silc_server_send_notify_server_signoff to send the
5455 SERVER_SIGNOFF notify type. Deprecates the function
5456 silc_server_send_remove_id.
5458 Added also silc_server_send_notify_signoff to send the
5459 SIGNOFF notify type.
5461 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5462 SILC protocol from this day on. Changed the protocol
5463 specification as well.
5465 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5466 notify type. It is used between routers to notify about
5467 topic changes on a channel.
5469 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5472 * Partly updated the protocol specification to comply with the
5473 changes now made. It is still though a bit outdated.
5475 * The JOIN notify type now takes one extra argument <Channel ID>.
5476 The packet used to be destined to the channel but now the
5477 JOIN type may be sent as list thus it is impossible to
5478 destine it to any specific channel. By adding this argument
5479 it is again possible.
5481 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Added CREDITS file. The CHANGES and CREDITS file will appear
5484 in the distribution as well.
5486 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5489 types in the server's silcd/packet_receive.c.
5491 * Implemented CMODE and CUMODE to work in router environment.
5493 * Fixed minor encoding and decoding buglet from the
5494 lib/silccore/silcmode.c.
5496 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5499 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5501 * Changed all SilcConfigServer* and silc_config_server* to
5502 SilcServerConfig* and silc_server_config*, respectively.
5505 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Associated the ID (client or server ID) to the Authentication
5508 Payload to avoid any possibility of forging. Updated the
5509 protocol specification and the code accordingly.
5511 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * The RSA key length is now save to the RsaKey context in the
5514 key generation process in lib/silccrypt/rsa.c. The key length
5515 is now used to figure out the maximum size of the block allowed
5516 to be encrypted/signed.
5518 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5519 is equivalent to the silc_mp_mp2bin but does not allocate any
5522 * Changed silc_mp_mp2bin API to take length argument. If it is
5523 non-zero then the buffer is allocated that large. If zero, then
5524 the size is approximated using silc_mp_sizeinbase, which however
5527 * Created Global RNG API which is global RNG that application can
5528 initialize. After initializing, any routine anywhere in the
5529 code (including library) can use RNG without allocating a new
5530 RNG object. This was done to allow this sort of use of the
5531 RNG in code that has no chance to allocate RNG object. All
5532 applications currently allocate this and many routines in the
5533 library use this. Affected file lib/silccrypt/silcrng.[ch].
5535 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5536 it to use the Global RNG API.
5538 * Defined Authentication Payload into protocol specification that
5539 is used during SILC session to authenticate entities. It is
5540 used for example by client to authenticate itself to the server
5541 to obtain server operator privileges.
5543 Implemented this payload into the lib/silccore/silcauth.[ch].
5544 Implemented also routines for public key based authentication
5545 as the new protocol specification dictates.
5547 Moved definitions of different authentication methods from
5548 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5550 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5551 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5552 silc_pkcs_verify_with_hash functions into the file
5553 lib/silccrypt/silcpkcs.[ch].
5555 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * The client entry's userinfo pointer must be always valid.
5558 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5559 will fail since it requires the userinfo. Now, the userinfo
5560 is allocated as "" if actual userinfo does not exist. Actually,
5561 it must exist and it is totally Ok to drop client connections
5562 that does not announce the userinfo. However, we will make
5563 this workaround for now.
5565 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5566 to return the remote port by socket.
5568 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5571 SILC_SERVER_PENDING_EXEC and added an new macro
5572 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5573 data or when error occurs while processing the pending command.
5575 Added new argument `destructor' into silc_server_command_pending
5576 and to the SilcServerCommandPending object. This destructor is
5577 now called after calling the pending callback or if error occurs
5578 immediately. If error occurs the actual pending callback won't
5579 be called at all - only the destructor. The destructor may be
5580 NULL if destructor is not needed.
5582 All this applies for client library code as well. Similar
5583 changes were made there as well for the pending commands.
5585 In the client, the application must now allocate the
5586 SilcClientCommandContext with the silc_client_command_alloc
5589 * Added reference counter to the SilcServerCommandContext. Added
5590 function silc_server_command_alloc and silc_server_command_dup
5593 Same type of functions added to the client library for the same
5596 * Removed the cmd_ident from IDListData away since it is now
5597 global for all connections. It is the command identifier used
5598 in command sending and with pending commands. The affected file
5601 * Added reference counter to the SilcSocketConnection objecet to
5602 indicate the usage count of the object. The object won't be
5603 freed untill the reference counter hits zero. Currently only
5604 server uses this, and client ignores it. The client must be
5605 set to use this too later. The affected files are
5606 lib/silccore/silcsockconn.[ch]. Added also the function
5607 silc_socket_dup to increase the reference counter.
5609 This was mainly added because it is possible that the socket
5610 is removed underneath of pending command or other async
5611 operation. Now it won't be free'd and proper DISCONNECTING
5612 flags, etc. can be set to avoid sending data to connection that
5613 is not valid anymore.
5615 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5616 the connection. After that it sets SILC_SET_DISCONNECTED.
5617 It is, however, possible that the socket data is not still freed.
5618 The silc_server_packet_process now checks that data is not
5619 read or written to connection that is DISCONNECTED. The socket
5620 get's freed when the reference counter hits zero.
5622 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Changed the client operation API: channel_message operation's
5625 `sender' is now the client entry of the sender, not the nickname
5626 and the `channel' is the channel entry, not the channel name.
5628 In the private_message operation the `sender' is now also the
5629 client entry of the sender not the nickname.
5631 Affected file is lib/silcclient/ops.h and all applications
5632 using the client operations.
5634 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Moved the calling of ops->connect() from connect_to_server_final
5637 into receive_new_id functin since that is the point when the
5638 client is actually allowed to send traffic to network. The
5639 affected file is lib/silcclient/client.c.
5641 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5644 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5645 (if needs broadcasting) instead of broadcasting the packets one
5646 by one which would make a burst in the network traffic.
5648 * Added `broadcast' argument to the functions in silcd/server.[ch]
5649 silc_server_create_new_channel[_with_id] to indicate whether
5650 to send New Channel packet to primary router.
5652 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added new function into the silcd/server.[ch] files:
5655 silc_server_create_new_channel_with_id to create new channel with
5656 already existing Channel ID.
5658 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5659 lib/silccore/silcpacket.h. This packet is used t send list of
5660 Set Mode payloads inside one packet. Server uses this to set
5661 the modes for the channels and clients on those channels, that it
5662 announced to the router when it connected to it. The protocol
5663 specification has been updated accordingly.
5665 * The silc_server_new_channel did not handle the packet coming
5666 from normal server as it normally does not send that. However,
5667 when it announces its channels it does send it. Implemented
5668 the support for that.
5670 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5671 into the file lib/silccore/id.h.
5673 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Fixed memory leaks in the functions silc_idlist_del_client,
5676 silc_idlist_del_channel and silc_idlist_del_server in the file
5677 silcd/idlist.c. All of those leaked like a sieve.
5679 * Fixed some small memory leaks in the client's function
5680 silc_client_notify_by_server.
5682 * Added functions into silcd/server.c: silc_server_announce_clients,
5683 silc_server_announce_channels and silc_server_announce_server.
5684 These functions are used by normal and router server to announce
5685 to its primary router about clients, channels and servers (when
5686 router) that we own. This is done after we've connected to the
5689 These functions effectively implements the following packet types:
5690 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5691 and SILC_PACKET_NEW_ID_LIST.
5693 * Added new functions into the silcd/packet_receive.[ch]:
5694 silc_server_new_id_list, silc_server_new_channel_list and
5695 silc_server_new_channel_user_list to handle the incoming
5696 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5698 * Added support of changing Channel ID in the function
5699 silc_server_replace_id. If the server that announces a channel
5700 to the router already exists in the router (with same name but
5701 with different Channel ID), router is responsible to send
5702 Replace ID packet to the server and force the server to change
5703 the Channel ID to the one router has.
5705 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5706 client that the Channel ID has been changed by the router. The
5707 normal server sends this to the client. Client must start using
5708 the new Channel ID as the channel's ID.
5710 Implemented handling of this new type into lib/silcclient/client.c
5711 into the function silc_client_notify_by_server.
5713 * Added new function silc_idlist_replace_channel_id into the files
5714 silcd/idlist.[ch] to replace the Channel ID.
5716 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Call silc_server_command_identify_check always when processing
5719 the IDENTIFY command in silcd/command.c
5721 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5724 send keepalive packets. The packet can be sent by clients,
5725 servers and routers.
5727 Added function silc_socket_set_heartbeat into the file
5728 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5729 If not set, the heartbeat is not performed. The actual
5730 heartbeat is implemented in the low level socket connection
5731 library. However, application is responsible of actually
5734 Added silc_server_send_heartbeat to send the actual heartbeat
5735 packet into silcd/packet_send.[ch]. Server now performs
5736 keepalive with all connections.
5738 * Added silc_task_get_first function into lib/silcutil/silctask.c
5739 to return the timeout task with shortest timeout. There was a bug
5740 in task unregistration that caused problems. TODO has been
5741 updated to include that task system must be rewritten.
5743 * The client library will now resolve the client information when
5744 receiving JOIN notify from server for client that we know but
5745 have incomplete information.
5747 * Rewrote parts of silc_server_remove_from_channels and
5748 silc_server_remove_from_one_channel as they did not remove the
5749 channel in some circumstances even though they should've.
5751 * Encryption problem encountered in server:
5753 The LEAVE command used to send the Channel Key packet to the
5754 router immediately after generating it. However, the code
5755 had earlier sent Remove Channel user packet but not immediately,
5756 ie. it was put to queue. The order of packets in the router
5757 was that Channel Key packet was first and Remove Channel User
5758 packet was second, even though they were encrypted in the
5759 reverse order. For this reason, MAC check failed. Now, this
5760 is fixed by not sending the Channel Key packet immediately but
5761 putting it to queue. However, this is more fundamental problem:
5762 packets that are in queue should actually not be encrypted
5763 because packets that are sent immediately gets encrypted
5764 actually with wrong IV (and thus MAC check fails). So, packets
5765 that are in queue should be encrypted when they are sent to
5766 the wire and not when they put to the queue.
5768 However, the problem is that the current system has not been
5769 designed to work that way. Instead, the packet is encrypted
5770 as soon as possible and left to the queue. The queue is then
5771 just purged into wire. There won't be any fixes for this
5772 any time soon. So, the current semantic for packet sending
5775 o If you send packet to remote host and do not force the send
5776 (the packet will be in queue) then all subsequent packets to the
5777 same remote host must also be put to the queue. Only after the
5778 queue has been purged is it safe again to force the packet
5781 o If you send all packets immediately then it safe to send
5782 any of subsequent packets through the queue, however, after
5783 the first packet is put to queue then any subsequent packets
5784 must also be put to the queue.
5786 Follow these rules and everything works fine.
5788 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added new function silc_server_remove_clients_by_server to
5791 remove all client entries from ID list when the server connection
5792 is lost. In this case it is also important to invalidate all
5793 client entires as they hold the invalid server entry. This
5794 fixes fatal bug when server has lost connection and will reconnect
5797 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Made some sanity checks to silc_server_daemonise like to check
5800 whether the requested user and group actually exists.
5802 * Added sanity check to SKE's silc_ske_responder_finish to check
5803 that the public and private key actually is valid.
5805 * Invalidate the client's nickname when receiving Replace ID
5806 packet and the Client ID is being replaced. This means that the
5807 server will query the nickname if someone needs it (client)
5810 * Sort the ID Cache in client library when the ID Cache data
5811 has changed (needs sorting).
5813 * Do not allow for SILC client to create several connections to
5814 several servers. The client does not support windows right now
5815 and generating multiple connections causes weird behaviour.
5817 Irssi-silc client does support windows and can handle several
5818 connections without problems, see: www.irssi.org and SILC plugin.
5820 * Fixed some places where client was added to the IDList. The
5821 rule of thumb is following (in order to get everything right):
5822 If the client is directly connected local client then the
5823 `connection' argument must be set and `router' argument must be
5824 NULL to silc_idlist_add_client function. If the client is not
5825 directly connected client then the `router' argument must
5826 bet set and the `connection' argument must be NULL to the
5827 silc_idlist_add_client function.
5829 * The funtion silc_server_packet_send_local_channel actually did
5830 not check whether the client was locally connected or not. It
5831 does that now. Fixed a bug related to LEAVE command.
5833 * Fixed Remove Channel User payload parsing bug in server's
5834 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5836 * The server's silc_server_save_channel_key now checks also the
5837 global ID list for the channel as it might not be in the local
5838 list. Fixed a bug related to LEAVE command.
5840 * Is this the end of the [<unknown>] buglet that has been lurking
5841 around for a long time? A little for loop fix in server's
5842 silc_server_command_whois_parse that is used by both IDENTIFY
5843 and WHOIS command. At least, this was a clear bug and a cause
5844 of one type of [<unknown>] buglet.
5846 * WHOIS and IDENTIFY commands call the function
5847 silc_server_command_[whois/identify]_check function even if
5848 we are not router server.
5850 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Added --with-gmp configuration option. If set the GMP
5853 is always compiled in the SILC source tree. If not set then
5854 it is checked whether the system has the GMP3 installed. If
5855 it has then the GMP won't be compiled (the system's headers
5856 and library is used), if it doesn't have it then the GMP is
5857 compiled in the SILC source tree.
5859 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Changed RSA private exponent generation to what PKCS #1
5862 suggests. We try to find the smallest possible d by doing
5863 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5864 not security fix but optimization.
5866 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Added new config entry [Identity] to fork the server and run
5869 it as specific user and group. A patch from Bostik.
5871 * Imported Dotconf configuration library into lib/dotconf.
5872 This will be used to create the SILC configuration files later.
5873 It will appear in the distsribution after this commit.
5875 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * A big code auditing weekend happening. Auditing code for
5878 obvious mistakes, bugs and errors. Also, removing any code
5881 Removed files for being obsolete:
5883 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5884 inline in the file lib/silcutil/silcbuffer.h)
5886 o lib/silcutil/silcbufutil.c (the header has inline versions)
5888 Changed code to fix possible error conditions:
5890 o The buffer formatting routines now check that the destination
5891 buffer really has enough space to add the data. This applies for
5892 both buffer formatting and unformatting
5893 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5894 unformatting was changed to accomodate following rules:
5895 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5896 sent to the function while XXX_*STRING will not allocate or copy
5897 the data into the buffer. Instead it sets the pointer from the
5898 buffer into the pointer sent as argument (XXX_*STRING used to
5899 require that the pointer must be allocated already). This change
5900 makes this whole thing a bit more consistent and more optimized
5901 (note that the data returned in the unformatting with XXX_*STRING
5902 must not be freed now). The routines return now -1 on error.
5904 o Tried to find all code that use buffer_format and buffer_unformat
5905 and added return value checking to prevent formatting and
5906 especially unformatting errors and possible subsequent fatal
5909 o Changed ske->x and ske->KEY to mallocated pointers in
5910 lib/silcske/silcske.h. Fixed possible data and memory leak.
5912 o Added return value checking to all *_parse* functions. Fixed
5913 many memory leaks as well.
5915 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5916 so that buffer overflows would not happen. All code now also
5917 checks the return value as it can fail.
5919 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added reconnection support to server if the normal server looses
5922 its connection to the router (for example if router is rebooted).
5923 The server performs normal reconnection strategy implemented
5924 to the server. Affected file silcd/server.c.
5926 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Added new packet type SILC_PACKET_SET_MODE that is used to
5929 distribute the information about changed modes (for clients,
5930 channels and clients channel modes) to all routers in the
5931 network. Updated the protocol specification accordingly.
5933 Added functions into silcd/packet_send.c and
5934 silcd/packet_receive.c: silc_server_send_set_mode,
5935 silc_server_set_mode.
5937 Added new files silcmode.[ch] into lib/silccore that implements
5938 the encoding and decoding of Set Mode Payload. Added new type
5939 SilcSetModePayload. Moved the definitions of different modes
5940 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5942 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Oops, a little mistake in server's connection authentication
5945 protocol. The protocol is not ended with FAILURE but with
5946 SUCCESS if the authentication is Ok. :) Affected file is
5949 * Implemented NICK_CHANGE notify handling in server in the file
5950 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5951 the local clients on the channel. After the changing nickname
5952 in router environment snhould work and the [<unknown>] nickname
5953 should appear no more.
5955 The silc_server_replace_id function that receives the Replace ID
5956 payload now sends the NICK_CHANGE notify type also in the file
5957 silcd/packet_receive.c
5959 * Changed WHOIS and IDENTIFY command to support the maximum amount
5960 of arguments defined in protocol specs (3328 arguments). This
5961 fixed a bug that caused problems when there were more than three
5964 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Added extra parameter, command identifier, to the
5967 silc_client_send_command so that explicit command identifier
5970 Changed that ID list routines uses specific command identifier
5971 when sending WHOIS/IDENTIFY requests to the server so that they
5972 can be identified when the reply comes back.
5974 Affected files lib/silcclient/command.[ch],
5975 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5977 * Added `sender' argument to silc_server_packet_send_to_channel
5978 to indicaet the sender who originally sent the packet to us
5979 that we are now re-sending. Ignored if NULL. Affected file
5980 silcd/packet_send.[ch].
5982 * Added some server statistics support in silcd/server_internal.h
5983 SilcServerStatistics structure and around the server code. Also
5984 send some nice statistics information when client is connecting
5987 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Fixed channel ID decoding in server's JOIN command reply in
5990 silcd/command_reply.c
5992 * Fixed braodcasting of replace ID payload to not to send it if
5993 we are standalone server in silcd/packet_receive.c.
5995 * Fixed all channel message sending routines to not to send
5996 packets to clients that has router set, since they are routed
5997 separately in the same function earlier. Affects file
5998 silcd/packet_send.c and all channel packet sending functions.
6000 * In USERS reply, res_argv[i] are not allocated, the table
6001 is allocated. Thus changed that free the table, not its
6004 * In server's whois_check and identify_check if the client is
6005 locally connected do not send any WHOIS commands - they are not
6008 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Fixed some minor bugs in client when sending WHOIS command. The
6011 arguments was in wrong order.
6013 * Removed statis function add_to_channel from server in
6014 silcd/command.c that was previously used with the joining but
6017 * Tested USERS command in router environment successfully with two
6018 routers, two servers and two clients.
6020 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Reorganized the USERS command and command reply in client library
6023 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6024 When the command is given by user we register a pending command
6025 callback that will reprocess the command after the reply has been
6026 received from the server. When reprocessing the packet we then
6027 display the information. Thus, the USERS information is displayed
6028 now in the command callback instead of in the command reply
6029 callback. The processing of the command is same as previously
6030 when server has sent the command reply in the JOINing process.
6032 * Added to USERS command in silcd/command_reply.c to join the client,
6033 we didn't use to know about, to the channel after we've created
6034 a client entry for it. Also, for clienet we did know already still
6035 check whether it is on the channel or not and add it if not.
6037 * Removed silc_server_command_join_notify as the function and its
6040 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Changed the client's pending command handling to the same as the
6043 server's pending command handling. It is also now possible to
6044 execute command reply functions from other command reply
6045 function as the function callbacks for commands and command
6046 replies are one and same. The pending commands are not static
6047 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6048 in client connection context. Thus, pending commands are server
6049 connection specific as it is convenient.
6051 Changed the function silc_client_command_pending and
6052 silc_client_command_pending_del and added new function
6053 silc_client_command_pending_check. Removed the
6054 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6057 * Added cmd_ident, current command identifier, to the client
6058 connection context in lib/silcclient/client.h to keep track on
6059 command identifiers used in command sending. Client's command reply
6060 function handling now supports the mandatory command identifiers.
6062 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6063 funtions in client to fully support pending command callbacks.
6065 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6066 as one of the arguments to the application in the command reply
6069 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6070 before first releasing SILC but came back. Now it is removed again
6071 and should come back nomore. The FORWARDED flag was used only
6072 by the JOINing procedure by forwarding the command packet to router.
6073 Now, the JOINing procedure has been changed to more generic (due
6074 to various router environment issues) and FORWARDED is not needed
6075 anymore for anything. The protocol specification is yet to be
6078 Now, removed silc_server_packet_forward from server and the flag
6079 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6081 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Renamed NAMES command to USERS command. The NAMES was named that
6084 due to historical reasons. Now it is renamed. Also, rewrote
6085 parts of the USERS command. The nickname list is not sent anymore
6086 by the server. Only Client ID and mode lists are sent in the USERS
6087 command. Changed this also to the protocol specification.
6089 The client now resolves the names and stuff after it receives
6090 the USERS list from the server when joining to the channel.
6092 * WHOIS and IDENTIFY commands has been changed to support multiple
6093 Client ID's per command. One can now search for multiple users
6094 in the network by sending only one WHOIS or IDENTIFY command.
6095 Changed the code and the protocol specifications.
6097 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6098 uses silc_server_command_whois_parse to parse the request. */
6100 * If normal server, do not parse the WHOIS and IDENTIFY requests
6101 before sending it to the router. Saves some time.
6103 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Fixed JOIN command on client library. Wrong number of arguments
6106 used to crash the client.
6108 * Added silc_server_channel_has_global function to check whether
6109 channel has global users or not.
6111 * Added silc_server_channel_has_local function to check whether channel
6112 has locally connected clients on the channel.
6114 * The silc_server_remove_from_one_channel now checks whether the
6115 channel has global users or not after given client was removed from
6116 the channel. It also checks whether the channel has local clients
6117 on the channel anymore. If it does not have then the channel entry
6118 is removed as it is not needed anymore.
6120 * The silc_server_notify now checks on JOIN notify whether the joining
6121 client is one of locally connected or global. If it is global then
6122 the channel has now global users on the channel and that is marked
6123 to the channel entry. Also, it now saves the global client to
6124 global list who is joining and JOINs it to the channel. This is
6125 for normal server, that is.
6127 Changed silc_server_send_notify_on_channel,
6128 silc_server_packet_relay_to_channel and
6129 silc_server_packet_send_to_channel check if we are normal server
6130 and client has router set (ie. global client) do not send the
6131 message to that client, as it is already routed to our router.
6133 * Implemented LEAVE notify type handling in silc_server_notify
6136 * Tested LEAVE command in router environment successfully. Tested
6137 with two routers, two servers and two clients.
6141 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6143 * Implemented SIGNOFF notify type handling in silc_server_notify
6146 * silc_server_remove_id now removes the client entry from all channels
6147 it has joined and thusly sends SIGNOFF notify type.
6149 * Rewrote the NAMES list generation in server by removing two excess
6150 loops. The lists are created now inside one loop.
6152 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * silc_server_remove_channel_user checks now also global list
6155 for channel and client.
6157 * silc_server_new_channel_user checks now both local and global
6158 list for channel and client. Fixed a bug in client id decoding.
6159 Used to decode wrong buffer.
6161 * silc_server_channel_message checks now both local and global
6162 list for channel entry.
6164 * Tested channel joining (hence JOIN) in router environment
6165 successfully. Tested with two routers, two servers and two
6168 * Tested channel message sending in router environment successfully.
6170 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Added silc_server_save_channel_key into server.[ch] to save the
6173 received channel key in Channel Key payload processing. It is
6174 also used in JOIN command reply handling.
6176 Equivalent function silc_client_save_channel_key added into
6177 client.[ch] into client library.
6179 * Changed JOIN command reply to send information whether the channel
6180 was created or not (is existing already) and the channel key
6181 payload. Changed protocol specs accordingly.
6183 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6184 the request was sent by ID and not by nickname. Crashed on
6187 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6190 now correctly save the received data.
6192 * silc_server_free_sock_user_data now notifies routers in the
6193 network about entities leaving the network.
6195 At the same time implemented functions silc_server_remove_id
6196 and silc_server_send_remove_id to receive and send REMOVE_ID
6197 packets. The packet is used to notify routers in the network
6198 about leaving entities. The ID removed will become invalid in
6201 * Added function silc_idlist_del_server into server. Removes and
6202 free's server entry from ID list.
6204 * silc_server_private_message function now checks, if we are router,
6205 that the destination ID really is valid ID, naturally.
6207 * In router when NEW_ID packet is received (for new client) the
6208 hash of the Client ID is saved in the ID Cache but the
6209 client->nickname is set to NULL, instead of putting the hash
6212 IDENTIFY command now also checks that client->nickname must be
6213 valid. If it is not if will request the data from the server who
6214 owns the client. Added new function
6215 silc_server_command_identify_check.
6217 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6218 to set the command to already allocated Command Payload.
6220 * Tested private message sending in router environment with two
6221 routers, two servers and two clients. Fixed minor bugs and now
6224 * Fixed segfault from client's NAMES command. Used to crash if
6227 * Forwarded packets must not be routed even if it is not destined
6228 to the receiver. Changed server code comply with this.
6230 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Added `require_reverse_mapping' boolean value to ServerParams
6233 structure. If TRUE (not default) the server will require that
6234 the connecting host has fully qualified domain name.
6236 If the reverse mapping is not required and hostname could not be
6237 found the IP address is used as hostname.
6239 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Implemented version string checking to both client and server.
6242 The check is incomplete currently due to the abnormal version
6243 strings used in development version of SILC.
6245 * Changed all command functions in server to use the new
6248 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Changed char *data to unsigned char *data in ID Cache system to
6251 support binary data as ID Cache data. Changed code to support
6252 binary data in lib/silccore/idcache.c.
6254 * Renamed silc_server_packet_relay_command_reply to
6255 silc_server_command_reply as it is normal packet receiving
6256 function. Rewrote the function to accept command replys for
6257 servers and not only for clients.
6259 * Mark remote router always as registered server if we are connecting
6260 to it. Otherwise, commands sent by the router to us are ignored.
6262 * All ID List find routines now returns the ID Cache Entry pointer
6263 as well if requested.
6265 * WHOIS command works now in router environment, tested with two
6266 routers, two servers and two clients.
6268 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6269 in router environment (as it is almost equivalent to WHOIS) but
6270 hasn't been tested thoroughly. Added new functions:
6272 silc_server_command_identify_parse
6273 silc_server_command_identify_send_reply
6274 silc_server_command_identify_from_client
6275 silc_server_command_identify_from_server
6277 * Disabled route cache adding because adding two different ID's with
6278 same IP replaces the old cache entry thus giving wrong route.
6279 The entry->router->connection is always the fastest route anyway
6280 so route cache may not be needed. Of course, new routes maybe
6281 established after receiving the ID when the entry->router->connection
6282 might not be anymore the most optimal.
6284 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Add route cache for received ID for fast routing.
6288 * Added silc_server_packet_route to route received packet on router
6289 that is not destined to us.
6291 * Renamed silc_server_get_route to silc_server_route_get.
6293 * Added id_string and id_string_len fields into SilcServer to
6294 include encoded ServerID for fast comparing without excess
6295 encoding of the ID's.
6297 * Cleaned up WHOIS command on server side. Added following static
6300 silc_server_command_whois_parse
6301 silc_server_command_whois_check
6302 silc_server_command_whois_send_reply
6303 silc_server_command_whois_from_client
6304 silc_server_command_whois_from_server
6306 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6307 arguments in command replies. All command functions should be
6308 updated to use this macro.
6310 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Minor typo fixes on command reply handling on server.
6314 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added silc_server_command_add_to_channel internal routine to add
6317 the client to the channel after router has created the channel and
6318 sent command reply to the server.
6320 * Added generic silc_server_send_command to send any command from
6323 * Use static buffer with ID rendering instead of duplicating data.
6325 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Fixed a channel user mode bug when joining to a channel server gave
6328 everybody channel founder rights, oops.
6330 * We mark ourselves as the router of the incoming server connection
6331 if we are router ourselves. This way we can check in some packet
6332 sending functions whether it is locally connected server. For
6333 incoming router connections we put NULL.
6335 * For router sending packets locally means now always sending the
6336 packet cell wide; to local clients and local servers. For normal
6337 server sending packet locally means sending it to only local
6340 * Fixed the JOIN command to really work in router environment. If the
6341 channel is created it is always created by the router. Router is
6342 also responsible of making the initial joining to the channel,
6343 sending JOIN notify to the sending server and distributing
6344 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6345 does not exist server doesn't do anything else but forward the
6346 command to the router which performs everything.
6348 * Added silc_server_send_channel_key function to send the Channel Key
6351 * Added silc_server_create_channel_key to create new channel key. The
6352 channel key is now re-generated everytime someone joins or leaves
6353 a channel, as protocol dictates. Note: channel->key_len is the
6356 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6359 packet_receive.[ch] to separate packet sending and receiving
6360 routines. The server.[ch] now includes everything else including
6361 actual packet processing (writing and reading data) and other
6364 Renamed silc_server_private_message_send_internal to
6365 silc_server_send_private_message. The routine is still though
6366 used only to relay private messages as server does not send
6367 private messages itself.
6369 Renamed silc_server_new_channel to silc_server_create_new_channel
6370 and added new function sicl_server_new_channel that handles the
6371 incoming New Channel packet. Added also new sending function
6372 silc_server_send_new_channel to send New Channel Payload.
6374 * Added new function silc_server_notify to process incoming notify
6375 packet to the server/router. Server may then relay the notify
6376 to clients if needed.
6378 * Added new function silc_server_new_channel_user to process incoming
6379 New Channel User packet. Router will redistribute the packet and
6380 send JOIN notify to its local clients and locally connected servers
6381 if needed. Normal server will send JOIN notify to its local client
6382 on same channel when received this packet. Added also corresponding
6383 sending function silc_server_send_new_channel_user to sent the
6386 * Added boolean route argument to send_notif_to_channel and
6387 packet_send_to_channel functions to attempt to route the packet
6388 if it is TRUE and send only locally if it is FALSE.
6390 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * silc_server_replace_id now broadcasts the received replace ID
6393 packet if it is not broadcast packet already. The router must
6394 broadcast to inform other routers about changed ID.
6396 * Added backpointer to server's router into SilcServer context in
6397 silcd/server_internal.h.
6399 * Fixed silc_server_packet_broadcast to send correct broadcast
6402 * The channel key is now distributed to the local client as soon
6403 as it is received from the router (in router environment) so that
6404 no other packet may be sent for the channel until client has
6407 * silc_server_remove_channel_user now broadcasts the received
6408 Remove Channel User packet if it is not broadcast packet already.
6409 The router must broadcast to inform other routers about removed
6412 * Added users field into SilcPacketContext that is a reference count
6413 of the context. One can increase the reference count by calling
6414 silc_packet_context_dup which is now changed to just increase the
6415 reference count instead of duplicating the data. The reference
6416 count is decresed by calling silc_packet_context_free that will
6417 free the data after the reference count hits zero.
6419 For now on the packet context and everything allocated into it
6420 (including the raw packet from network) must be freed by calling
6421 the new silc_packet_context_free function. Added also new function
6422 silc_packet_context_alloc that must be used now to allocate the
6423 context. This also means that if a routine is asynchronous from
6424 silc_[client/server]_packet_parse_type the packet context must
6425 be duplicated by calling silc_packet_context_dup. Otherwise it
6426 gets free'd after silc_[client/server]_packet_parse_type returns.
6427 Also, one must remember that if packet is duplicated then its
6428 reference count must be decresed by calling the free function as
6429 many times as it was duplicated.
6431 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6432 from both client and server.
6434 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Made joining to a channel working in router environment.
6438 * Cleaned up JOIN command on server side and create function
6439 silc_server_command_join_channel internal routine to make the
6442 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Changed silc_command_pending list to SilcDList. Also, added
6445 `ident' field to SilcServerCommandPending structure to identify
6446 the reply and to call correct callback.
6448 Added silc_server_command_pending_check function to replace the
6449 corresnponding macro. The silc_command_pending list is not
6452 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6453 to set identifier to previously allocated Command Payload. It
6454 is used to set identifier for command when resending Command
6457 * Added silc_command_payload_encode_payload to encode Command
6458 Payload buffer from SilcCommandPayload structure.
6460 * Added silc_argument_payload_encode_payload to encode Argument
6461 payload buffer from SilcArgumentPayload structure.
6463 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Changed WHOIS command to support router connection on server side.
6466 The whois request is always sent to router unless the server is
6467 standalone server. After server has received the reply from the
6468 router will it send the reply to the client.
6470 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6471 broadcast received broadcast packet. The function is used only
6472 by router. The broadcast packet is always sent to the router's
6475 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6476 render given ID to printable string, for log files for example.
6478 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Made basic router to router connections working. At least they
6481 can now connect to each other but nothing really works the way
6482 they are supposed - yet.
6484 * Added new initiator token to RouterConnection configuration
6485 file in silcd/serverconfig.[ch]. It is used to tell whether we
6486 are the initiator to the remote router or whether we'll expect
6487 the other end to connect.
6489 * Moved registering of listener task to silc_server_init, hence
6490 the server starts listenning as soon as it is run, even if it
6491 does not have connections to other routers. Let's see how well
6494 * Changed default connection retry timeouts for more suitable in
6497 * Removed cipher and such arguments from silc_idlist_add_client
6498 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6499 Added new function silc_idlist_add_data to add the keys and stuff
6502 * Added SilcIDListData structure and added it to SilcClientEntry
6503 and SilcServerEntry as their first field in the structure. This
6504 way we can explicitly cast the ID entries to the SilcIDListData
6505 structure and get common data for the entries. In past, we had
6506 to first check what type of connection it is and then cast it to
6507 correct ID entry type. Now, we can directly cast the opaque
6508 pointer to the SilcIDListData (no matter what ID entry it actually
6509 is) and get the data needed.
6511 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6514 in some circumstances even if threre were timeout tasks, though not
6515 IO tasks, but tasks anyway. Now fixed.
6517 * Defined SilcServerConnection structure to hold connection specific
6518 stuff about directly connected servers and routers. The definition
6519 is currently in silcd/server_internal.h. I thought about having
6520 a bit more important role fro this struct but for now it is used
6521 only when connecting to other server (or router actually).
6523 * Added connecting retry support in server when connecting to
6524 router(s). The retry feature implement exponential backoff
6525 algorithm. Also, added SilcServerParams structure to hold default
6526 parameters for server. For now, it include these retry settings
6527 and are hard coded. After server is moded to be as Silc Server
6528 Library this structure will be more important.
6530 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Changed client librarys channel->clients table to SilcList and
6533 changed code accordingly.
6535 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Changed client's channel table to SilcList and changed code
6538 accordingly. Also changed SilcChannelClientEntry to include back-
6539 pointer to the channel so that client entry can use that structure
6540 as list as well and we have fast cross-reference to the channel.
6541 This change dramatically decreased the complexity of channel
6542 handling with client entry and vice versa (removed one extra
6543 loop when searching for channel entry from many functions).
6545 * Changed server->sim from table to SilcDList and changed code
6548 * NAMES command can now be used from user interface. It will show
6549 the user list on the channel, neatly.
6551 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6552 Code now saves realname of the user if it becomes available.
6554 * Renamed configure.in to configure.in.pre and made ./prepare
6555 script to automatically add correct version string to
6556 configure.in which it creates from configure.in.pre.
6558 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * NAMES command reply now shows users mode with the nickname when
6563 * Moved silc_client_ch[u]mode[_char] functions from
6564 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6565 place sucks, they are utility functions and should be in some
6568 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6570 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6573 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Added TRQ (efficient deque and list library) into lib/trq. This is
6578 a very good list library that is currently used in the SILC. Defined
6579 SilcList API over the library because I didn't like the API very
6580 much. See lib/trq/silclist.h for the API and examples of how to
6581 use the API. Fixed various places in the code to use the new
6582 SilcList API. The SilcList is meant for lists that has a structure
6583 already defined as a list. It is not suitable to add just some
6584 context to the list (in TRQ, the context is the list actually).
6586 So, I defined SilcDList that can be used for the purpose where
6587 predefined list structure does not exit. This can be used as
6588 such list. Now some context just can be added to the SilcDList.
6589 Currently this list is not used in the SILC just yet, though there
6590 are a lot places where this can replace dynamically allocated
6591 tables and I will fix these places, later, to use SilcDList.
6592 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6593 and use TRQ internally).
6595 Also fixed some annoying warning messages that the original TRQ
6596 code generated. Also minor changes to TRQ's Makefile.in.
6598 * Added support for querying by Client ID to both WHOIS and
6599 IDENTIFY commands into server, as required by the protocol.
6601 * Removed method function pointers from SilcBuffer structure. They
6602 weren't used to anything and just increased the context size for
6603 no good reason. This change also made silc_buffer_alloc and
6604 silc_buffer_free functions inline functions.
6606 * Disabled command flooding detection support until it's fixed so
6607 that it accepts commands in but does not execute them more than once
6610 * Added silc_net_localhost(), to return local hostname, into
6611 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6612 that must be initialized before calling silc_client_init.
6614 * Added new function: silc_server_send_notify_on_channels to send
6615 notify messages to all channels client has joined. It is assured
6616 that the message is sent only once per client.
6618 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6619 lib/silcutil/silcutil.[ch] as silc_format function. The new
6620 function is generic and is used by server as well, not only by
6621 the logging routines.
6623 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6624 the provided version string was not acceptable. Added new function:
6625 silc_ske_check_version into lib/silcske/silcske.h. The function
6626 must be implemented by the application (client or server) and it
6627 does not reside in the SKE library. The function checks the version
6628 string remote end sent.
6630 * Added back pointers (to opaque context and to SilcSocketConnection)
6631 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6633 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6634 duplicate packet context structure.
6636 * Changed `notify' client operation to send same arguments as client
6637 receives from server except for ID's. ID's are mapped to correct
6638 ID entry and that is returned. Also, if channel entry is not sent
6639 by server but the notify is for channel the channel entry is sent
6640 to application (otherwise application doesn't know that it is for
6641 channel (library gets it from packet's Destination ID)).
6643 * Added silc_client_remove_from_channels into client library to
6644 remove a client from all channels it has joined to. Used when
6645 received SIGNOFF notify from server. Added also new function
6646 silc_client_replace_from_channels to replace old ID entry with
6647 new ID entry on all channels. Used when received NICK_CHANGE
6650 * Fixed ID Cache list handling in silc_idlist_get_client in
6651 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6652 to get (or query) client by ID.
6654 * Updated TODO list.
6656 * Added connection authentication status message defined by the
6657 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6658 support for these into the code in client and server side.
6660 * Added generic function silc_client_send_command to send any command
6661 with variable argument list. Application should use this function
6662 to send commands if the command functions provided by the library
6663 does not suite for the application's user interface needs.
6665 * Added new `failure' client operation. Application is notified about
6666 received failure packet if client is executing a protocol. In this
6667 case the protocol's execution has failed.
6669 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6670 is required by the protocol.
6672 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6673 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6676 * Added status flag to SilcSKE object to indicate realtime status
6677 of the SKE protocol.
6679 * Application receives now exactly same command reply arguments as
6680 the library receives from server. However, if ID is received the
6681 corresponding ID entry is returned to the application (eg. Client
6682 ID is mapped to correct SilcClientEntry entry and that is returned).
6683 Changed command_reply client operation due to this change.
6685 * Changed all ID's in commands and in command replys as ID Payloads.
6686 Change affected both client and server side codes.
6688 All ID's sent in SILC network (with execption of ID's in SILC
6689 Packet header) are sent in ID Payload to support variable length
6692 * Server now notifies nick changes and notifies all clients on
6693 the channels about the new nickname (about the new Client ID,
6696 * Implemented CMODE command to change channel modes. Supports all
6697 channel modes defined by the protocol specs except ban and invite
6698 lists. (Also, private channel key mode is supported but support for
6699 setting private channel key in client is missing, thus, this mode
6700 has no effect on client side (except that server requires that the
6701 client uses private channel key and normal channel traffic does not
6704 Also, invite mode works per se, but INVITE command does not work
6705 yet correctly, so you can set channel as invite only channel but
6706 inviting clients to the channel does not work (it is yet to be
6707 thought what's the best way to do it).
6709 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6710 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6711 Implemented CUMODE command to change user's mode on the channel.
6712 Supports all modes defined by the protocol specs.
6714 * Added NAMES command reply to return users modes on the channel.
6716 * Removed unnecessary and slow ciphers from lib/silccrypt.
6718 * Set SO_KEEPALIVE option to connection sockets by default.
6720 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6722 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6723 redefined the Notify Payload into protocol specs.
6725 * Added silc_id_payload_parse_id to get ID directly from raw
6728 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6731 accept searching by Client ID as well.
6733 * Added support for LEAVE and SIGNOFF notify types in client library.
6735 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6736 to parse ID Payload from raw data.
6738 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Added flags parameter into silc_ske_assemble_security_properties
6741 function in lib/silcske/silcske.[ch].
6743 * Changed notify client operation to fit better for notify messages
6744 sent by server. The notify payload received from server is now
6745 passed to the application (after parsing it to SilcNotifyPayload).
6746 It is application's responsibility to retrieve the arguments
6747 from the payload and show the message the way it wants. The message
6748 sent by server is implementation specific.
6750 * Changed public keys to comply with the protocol specification.
6751 Old public keys are not supported anymore and are not compatible.
6753 * Removed nickname from Channel Payload as the latest draft removed
6754 it. The client must resolve the nickname from the NAMES command
6755 reply received when it joined the channel.
6757 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6759 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Fixed some errors in protocol specification drafts.
6763 * Created lib/silccore/silcnotify.c to implement Notify Payload
6764 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6765 generic payloads described by protocol specifications. The file
6766 includes implementations for ID Payload and Argument Payload.
6768 * Changed Command Payload implementation to use the new Argument
6769 Payload. Changed command_xxxx_payload to command_payload_xxxx
6770 to comply with SILC coding conventions.
6772 * Added suppport for Argument Payload handling in Notify Payload
6773 implementation as protocol requires it. Added the new support
6774 into server and client lib as well.
6776 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Added support for multiple nicknames on same channel. [n] is
6779 added locally to the nickname if there are more than one same
6780 nicknames on the channel.
6782 * Server now sends all nicknames that matched WHOIS request.
6783 Client also shows the list received from server.
6785 * Added TOPIC command to client side. User can now set and show
6786 current topic on channel.
6788 * Added MOTD command to client and server. Also, server sends the
6789 motd when client connects to the server.
6791 * Changed version strings to comply ISO 8601.
6793 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Fixed protocol error handling in client library. It should now
6796 cope even if the SKE fails for some reason.
6798 * Made new protocol specification drafts for submitting to IETF.
6800 * Implemented TOPIC command to server in silcd/command.c.
6802 * Added two new notify types into lib/silccore/silcnotify.h:
6803 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6804 notify nickname change and topic setting/change on a channel.
6806 * API change of command_reply operation in client library. The
6807 application gets now the status type received from server as well.
6809 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6813 * Cras fixed and optimized the packet handling even further and
6814 it should work now. Minor change to the prototype of function
6815 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6817 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added new function into lib/silcutil/silcschedule.[ch]:
6820 silc_schedule_with_fd to select() a specified fd. The function
6821 returns after timeout expires or data arrives or goes. The
6822 function is used by packet routines to wait that all data is
6823 received from network.
6825 * Fixed data reading from network in lib/silccore/silcpacket.c.
6826 The code now assures that all data is read from the fd and then
6827 continues packet processing. This was a bug fix since the code
6828 used to drop some data in some circumstances.
6830 * Added new function into lib/silcclient/client.[ch]:
6831 silc_client_start_key_exchange to start key exchange after
6832 connection has been established to server. The code internally
6833 now uses this funtion but its main purpose was to provide it
6834 for applications that perform their own connecting. After
6835 application has created a connection it merely calls this
6836 function to start the key exchange between client and server.
6837 The library takes care of everything else after that.
6839 Updated also lib/silcclient/README to explain the usage of
6842 * Do not send to application information that connection has
6843 been established. Application gets notified it by connect
6846 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Applied cras's patch to add silc_schedule_one function. The
6849 function runs scheduler once and returns.
6851 * Fixed the scheduler after cras messed it up. The timeout
6852 handling works now as it's supposed to work.
6854 * Added into lib/silccore/ silcnotify.h to include notify
6855 message types support. Changed silc_server_send_notify*
6856 functions, in server.[ch], to support those new notify types.
6857 Added the support for the notify types into client library,
6858 as well. Added new notify client operation into ops.h in
6861 * Changed silc_server_packet_send_to_channel to send normal
6862 packets instead of just channel message packets. The function
6863 is now used to send the notify packets to channels. It is not
6864 used to send channel message packets anymore, as server never
6867 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6868 va_arg()s as it seems to require it nowadays. I guess, if SILC
6869 is compiled with older va_arg() the new code should work anyway.
6871 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Splitted core library. Core library (lib/silccore) includes
6874 now only SILC protocol specific core (and common) components.
6875 Created new utility library (lib/silcutil) that includes more
6876 generic purpose stuff. The stuff for util library was taken
6877 from the old core library. This was minor and easy split.
6879 * Created SILC Client Library (lib/silcclient) that includes
6880 implementation of the SILC client without user interface. This
6881 was major move from silc/ directory. The code has been changed
6882 so that it is transparent towards the user interface. The
6883 silc/ directory includes now the same user interface as before
6884 and it uses the new client library. Read lib/silcclient/README.
6885 Basicly, the client library performs everything else related
6886 to SILC except user interface handling. Also, configuration
6887 files are considered to be part of user interface and library
6888 does not handle them.
6890 This change also changed a lot of structures, function naming etc.
6891 Most important change was that SilcClientWindow object was
6892 renamed to SilcClientConnection in the client library. Created
6893 also new file lib/silcclient/ops.h. Also added new files
6894 silc/local_command.[ch] and silc/client_ops.[ch].
6896 All these changes were made to make it easier for user interface
6897 designers to create what ever user interface for the SILC client
6900 It is also expected that the server will be moved to lib
6901 directory as well and SILC Server Library will be created;
6902 sometimes in the future.
6904 * Removed Local commands from lib/silccore/silccommand.h as
6905 they are application specific and new client library does not
6906 handle any of those anymore.
6908 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6909 old client implementation in silc/.
6911 * Added support for callback functions in SILC_LOG_* macros.
6912 Application can now set its own callbacks that will be called
6913 instead of using the default functions that will always print
6914 the debug messages to stderr (or stdout). Also, debugging can
6915 now be disabled by setting silc_debug to FALSE and re-enabled by
6916 setting it to TRUE. Note, that logging will still work even
6917 if debugging is disabled.
6919 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6920 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6921 silc_log_reset_debug_callbacks.
6923 * To enable debugging in silc client one must give now -d
6924 option on command line.
6926 * Changed silc_schedule_init to automatically allocate task queues
6927 if they are not allocated before calling it.
6929 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added GMP 3.1 into math library.
6933 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6936 a channel in SILC network. The packet is used by servers and
6937 routers to notify other routers that user has left a channel.
6938 This little feature was missing until now. Added the feature
6939 to protocol specification as well.
6941 Added functions: silc_server_send_remove_channel_user and
6942 silc_server_remove_channel_user into server.[ch].
6944 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6945 lib/silccore/silcpacket.h. However, they are not implemented
6948 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Fixed joining to a channel and sending channel messages
6951 between server and router. The channel message sending should
6952 now work inside a cell.
6954 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Fixed the private message sending between server and router.
6957 The private message sending should now work inside a cell.
6959 * Added silc_server_replace_id into server.[ch] to replace
6960 existing ID in the SILC network.
6962 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6963 and silc_idlist_replace_server_id into idlist.[ch] in server.
6965 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Fixed the server to server connections. Server can again now
6968 connect to router. Router to router connections probably does
6971 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added dynamic protocol registering support. Now protocols can
6974 registered and unregistered on the fly. Patch by cras.
6976 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Added lib/contrib directory to hold routines that some platforms
6979 don't have but are needed by SILC.
6981 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6982 into lin/contrib to provide getopt() and getopt_long() for
6983 those who don't have it.
6985 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Added AWAY command to client. When away message is set and
6988 client receives a private message packet the client automatically
6989 replies to the sender with the away message.
6991 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6992 bug seemed to be the cause of recent problems when compiling
6995 * Added version detection support to SKE protocol specification
6996 and added the new changes to the SKE implementation as well.
6997 There were other minor changes in the SKE protocol as well.
6999 Many changes in lib/silcske/silcske.[ch] and in
7000 lib/silcske/payload.[ch].
7002 * Added ^U functionality, clear input line. Patch from cras.
7004 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Mainly small bugfixes on core library. Fixed some debugging
7007 logging and buffer overflow in silclog.c.
7009 * Updated config.sub and config.guess on the distribution tree.
7011 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Added command lagging support in server. Client may execute
7014 commands now only once in two seconds.
7016 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Optimized packet reception. MAC computation and checking is now
7019 also more optimized. A lot previously duplicated code is now
7020 used as generic by both client and server.
7022 * Fixed key pair generation in clientutil.c
7024 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Added into lib/silccore/silcbufutil.[ch] new function;
7027 silc_buffer_realloc.
7029 * Moved generic packet sending/encryption functions to
7030 lib/silccore/silcpacket.[ch] from client and server. Some
7031 rewriting of the functions.
7033 * Moved all generic packet reception/decryption functions to
7034 lib/silccore/silcpacket.[ch] from client and server. The
7035 packet processing is now much cleaner in both client and server.
7036 These were major changes in both client and server.
7038 * Created many common functions in server to do packet sending.
7039 Previously code were duplicated a lot, this has been removed
7042 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Rewrote major parts of the ID cache system. Don't know
7045 whether it is better now or not but at least the API is more
7048 * Major rewrite on ID cache stuff on client because of the ID
7049 cache API changes. Added idlist.c to client.
7051 * Also major rewrite on ID cache stuff on server as well.
7052 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7053 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7054 in hand, instead they are all put into the ID cache system now.
7055 All server_idlist_* routines uses ID cache now instead of
7056 traversing its own lists (those lists does not exist anymore).
7057 SilcIDList though still exists. Also, SilcXXXEntry's are
7060 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Finally made the SKE implementation compliant to the protocol
7063 specification. All mp integers are now binary encoded as
7064 opposed being HEX encoded.
7066 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7069 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7070 functions: silc_[encode/decode]_pem. Also added function
7071 silc_encode_pem_file to PEM encode with newlines ('\n') for
7074 * SILC public keys are now encoded either PEM or binary. Same
7075 option is for private keys as well. By default private keys
7076 are binary encoded and public keys PEM encoded. Silly HEX
7077 encoding were removed.
7079 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7080 function to create fingerprints.
7082 * Fixed a bug in SHA1; does not change the original data anymore.
7084 * Partly implemented INFO command on client and server side.
7085 Fixed CLEAR command. Changes to SERVER command; show current
7086 server(s) when giving command without arguments. Added
7087 VERSION command to client.
7089 * Added check to server that unregistered connections cannot
7090 execute commands (unless it is specificly allowed).
7092 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Fixed screen refresh.
7096 * Fixed channel joining bug from client. On some circumstances
7097 client tried to join to a channel it had already joined.
7099 * Added public key verification process into client's protocol.c.
7100 The client now verifies the public key from user and saves
7101 it into ~./silc/serverkeys/ directory.
7103 Added into: clientutil.[ch]: silc_client_verify_server_key.
7105 * Changed SKE protocol's silc_ske_initiator_finish function
7106 to accept callback function that verifies the received public
7107 key. Removed old silc_ske_verify_public_key function.
7109 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7112 silc_pkcs_private_key[_data]_set.
7114 * Made the password and public authentication more cleaner in
7115 server's protocol.c.
7117 * Removed historic and obsolete protocol `channel_auth' from
7118 both client and server.
7120 * Removed wrong way of sending command status messages from
7121 server to client in server's command.c. The old way violated
7122 protocol specification.
7124 Changes to silccore/silccommand.[ch]: removed
7125 silc_command_encode_status_payload -> not needed anymore,
7126 changed silc_command_encode_payload_va to accept extra
7127 argument on variable argument list. The argument type must
7128 now be provided to the function. Also, added new function:
7129 silc_command_encode_reply_payload_va which is same as
7130 normal command_encode_payload_va except command status type
7131 is provided as extra argument.
7133 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Added ~./silc directory handling. The directory includes the
7136 public and private keys for the client.
7138 Added silc_client_check_silc_dir, silc_client_create_identifier
7139 and silc_client_load_keys.
7141 * Implemented SILC protocol compliant public key. Added public
7142 and private key saving to and loading from files.
7144 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7145 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7146 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7147 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7148 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7150 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7151 silc_pkcs_load_[public/private]_key.
7153 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Added silc_server_get_route (route.[ch]) to get connection
7156 data for the fastest route for given ID.
7158 * Implemented INVITE command on client and server. The command
7159 were re-defined in the SILC Protocol Specification and the
7160 implementation now complies with the specification.
7162 * Implemented PING command on client and server.
7164 * Implemented NAMES command on client and server. The server side
7165 supports currently only normal server not router server yet.
7166 Some changes to NAMES definition in SILC protocol specification.
7168 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7170 * Implemented LEAVE command on client and server.
7172 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7173 again. This change was made to the protocol as well. Server
7174 should not violate the protocol specification anymore.
7176 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7179 was tested. SOCKS4 was not but should work anyway.
