23 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Added `user_count' to the SilcChannelEntry which now tells the
26 number of users on the channel. The user count is now saved
27 in normal server of global channels as well. Affected files
28 silcd/server.c, idlist.h, packet_receive.c and command.c.
30 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

47 the SKE interface a bit.
49 * Fixed padding problem in PKCS#1. The padding was not actually
50 random since the random number generator was used incorrectly.
51 This security bug affects only when encrypting with PKCS#1, and
52 it is not currently used at all in SILC. SILC only use signing
53 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
55 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

122 keepalive_secs, reconnect_count, reconnect_interval,
123 reconnect_interval_max, reconnect_keep_trying and
124 require_reverser_lookup. Added ConnectionParam block, and
125 implemented the connection parameters when connecting as
126 initiator and when accepting connections as responder.
128 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
129 whether given configuration value has been given already.
131 Affected files silcd/serverconfig.[c], server.[c].
133 * Splitted the doc/example_silcd.conf.in. Separated the crypto
134 algorithm parts and created new file silcalgs.conf, that
135 is now included from the example_silcd.conf.in.
137 * Optimized the silc_server_connect_to_router_second to take
138 the connection configuration object from the SilcServerConnection
139 object instead of finding it during the connecting phase.
140 Added the configuration object to SilcServerConnection struct.
141 Affected files silcd/server_internal.h, server.c.

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

221 hash algorithm. Affected file lib/silccrypt/silcrng.c.
223 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Fixed the file transfer's key agreement payload to include
226 zero port also if the hostname is NULL because it could not
229 Call file transfer monitor callback now also if error occurs
230 during key agreement protocol.
232 Changed the silc_client_file_send interface to return the
233 SilcClientFileError instead of session id. The session ID
234 is returned into pointer provided as argument.

251 file lib/silcutil/silclog.c.
253 * Fixed the channel message payload decryption in the function
254 silc_channel_message_payload_decrypt to not modify the original
255 buffer before it is verified that the message decrypted
256 correctly. Otherwise, next time it is called with correct
257 channel key it won't encrypt since the payload is corrupted.
258 Affected file lib/silccore/silcchannel.c.
260 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

273 the table with foreach callback. The current entry may
274 become invalid in the callback but it was referenced after
275 the callback returned.
277 Do not allow auto rehashing of hash table during the
278 silc_hash_table_foreach operation, for same reasons as it is
279 not allowed for SilcHashTableList. Affected files are
280 lib/silcutil/silchashtable.[ch].
282 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

294 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
296 * Added function silc_client_add_channel,
297 silc_client_replace_channel_id, and removed functions
298 silc_client_new_channel_id and silc_idlist_get_channel_by_id
301 * Added cross reference of the joined channels to the
302 SilcClientEntry, and changed the SilcChannelEntry's
303 users list to SilcHashTable. The affected files are
304 lib/silcclient/idlist.[ch].
306 * Fixed a bug in hash table tarversing. While the hash table
307 is traversed with SilcHashTableList the table must not be
308 rehashed. It is now guaranteed that auto rehashable tables
309 are not rehashed while tarversing the list. Also defined that
310 silc_hash_table_rehash must not be called while tarversing
311 the table. Added function silc_hash_table_list_reset that must
312 be called after the tarversing is over. The affected files are
313 lib/silcutil/silchashtable.[ch].
315 * Changed all hash table traversing to call the new
316 silc_hash_table_list_reset in server and in client library.
318 * Added function silc_client_on_channel to return the
319 SilcChannelUser entry if the specified client entry is joined
320 on the specified channel. This is exported to application as
321 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
323 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
325 * Fixed founder regaining problem with JOIN command on normal
326 server. The notify for mode change must be sent always and
327 not only if !cmd->pending. Affected file silcd/command.c.
329 * Fixed the WHOWAS command's reply sending to support the
330 lists correctly. Affected file silcd/command.c.
332 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * When sending JOIN command to router for processing the
335 sender's old command identifier was not saved back to the
336 sender's command context, fixed now. The affected file is
339 * Create the key in JOIN command of the router did not return
340 the channel key, added check for this. Affected file is
343 * Fixed a channel ID update bug in JOIN command reply. Do
344 not directly upgrade the ID but call the function
345 silc_idlist_replace_channel_id if the ID was changed.
346 Affected file silcd/command_reply.c.
348 * Fixed memory leaks from command calling if it would fail.
349 Affected file silcd/command.c.

361 * Removed TRQ from lib/trq, not needed anymore.
363 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
364 with server connections. Later this will be configurable
365 in config file after new config file is done. Affected file
368 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
370 * Fixed a crash in server related to channel announcements.
371 Affected file silcd/server.c.
373 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
375 * Fixed memory leaks in silc_server_create_new_channel*
376 functions. Affected file silcd/server.c.
378 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
379 which ID was changed. This way the router will send the
380 user list for the channel again, and server won't be in
381 desync in some rare circumstances. Affected file is
382 silcd/packet_receive.c.
384 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

413 file silcd/packet_receive.c and silcd/command.c.
415 * Fixed the SERVER_SIGNOFF notify handling on normal server
416 not to save the history information for clients. Same was
417 fixed earlier in remove_clients_by_server function, but not
418 here. Affected file silcd/packet_receive.c.
420 * Raised the default connection-retry count from 4 to 7 in
421 server. Affected file silcd/server.h.

436 local entry will always get the unformatted nickname.
437 Affected file lib/silcclient/idlist.c.
439 * Fixed some double frees from client library commands.
440 Affected file is lib/silcclient/command.c.
442 * Fixed CUMODE command in server to assure that no one can

444 little bug. Affected file silcd/command.c.
446 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Removed the SilcClientCommandDestructor from the client
449 libary, it is not needed anymore. Affected files are
450 lib/silcclient/silcapi.h, command[_reply].[ch],
451 client_notify, idlist.c.
453 * Fixed GETKEY command to first resolve client, and then
454 resolve the server only if the client was not found, instead
455 of resolving both at the same time. Affected file is
456 lib/silcclient/command.c.
458 * Added silc_client_start_key_exchange_cb and lookup the
459 remote hostname and IP address before starting the key
460 exchange with server. The affected file is
461 lib/silcclient/client.c.
463 * The server's public key is now saved using the IP address
464 of the server and not the servername for the filename.
465 The hostname public key filename is checked as an fall back
466 method if the IP address based filename is not found.
468 Fixed the GETKEY command to save the fetched server key
471 Print the remote server's hostname now when new key is
472 received during connection process. Affected file is
473 irssi/src/silc/core/client_ops.c.
475 * Return always our own public key to the client if it asks
476 for it with GETKEY command. Affected file silcd/command.c.
478 * Removed the use_auto_addr variable from default config
479 file since it was in wrong section. Affected file is
482 * Fixed TOPIC_CHANGE notification to not route it when it
483 was sent using silc_server_send_notify_to_channel function.
484 Affected file silcd/command.c.
486 * Fixed silc_server_send_notify_kicked to send the kicker's
487 Client ID also, it was missing. Affected files are
488 silcd/command.c, silcd/packet_send.[ch].
490 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Do not save client history information in SERVER_SIGNOFF.
493 Fixes the bug in normal server that it does not detect
494 the client becoming valid after the server becomes back
495 online. Affected file silcd/server_util.c.
497 * Added `sock_error' field into the SilcSocketConnection
498 context. When error occurs during socket operation (read
499 or write) the error is saved. Added also new function
500 silc_socket_get_error to return human readable socket error
501 message. Affected files are lib/silcutil/silcsockconn.[ch],
502 lib/silcutil/unix/silcunixsockconn.c, and
503 lib/silcutil/win32/silcwin32sockconn.c.
505 * The server now prints the socket error message in the
506 signoff for client. Affected file silcd/server.c.
508 * Fixed the `created' channel information sending from router
509 to server in JOIN command. Checks now whether the channel
510 really was created or not and set it according that.
512 Fixed the JOIN command to use the client entry's current
513 ID during the joining procedure instead of the one it sent
514 in the command (it is checked though), since it can change
515 between the packet processing and command processing, and
516 would just case unnecessary pain in the client end. Affected
517 file silcd/command.c.
519 * Fixed a channel key payload sending to use correct channel
520 ID when the server was forced to change the channel's ID by
521 router. Router sent the key payload with the old Channel ID.
522 Affected file silcd/packet_receive.c.
524 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Call silc_server_save_channel_key only if the key payload
527 was provided in the JOIN command's command reply. Affected

533 MPI. Affected file lib/silcmath/mp_mpi.c.
535 * Fixed the stop_server signal to correctly stop the scheduler
536 and gracefully stop the server when SIGTERM or SIGINT signals
537 are received. Affected file silcd/silcd.c.
539 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
541 * Simple handling of TERM and HUP signals. Also added some log
542 flushing call around. Affected file is
545 * Fixed small bugs in silclog.c. Now buffering output will take
546 effect after 10 seconds since startup: This will ensure that
547 no important startup messages are lost. Also output redirection
548 will preserve original format ([Date] [Type] message).
549 Affected file is lib/silcutil/silclog.c.
551 * Added two options to the config file, in the logging section:
552 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
553 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
555 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Do not print the warning about log files not being initialized
558 more than once to avoid excess logging. Affected file is
559 lib/silcutil/silclog.c.
561 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
562 the SIM copying in make install in Makefile.am.pre.

566 * Rewritten silclog APIs. Globally interesting changes follows:
567 silc_log_set_files() changed to silc_log_set_file().
568 silc_log_set_callbacks() changed to silc_log_set_callback().
569 ROBOdoc documented silclog header file.
570 SilcLogCb now returns bool to wether inihibit the default
571 handler or not (to keep the old behaviour return always TRUE).
572 The new APIs should also fix the problem of the
573 silcd_error.log file that was written in the current directory.
576 Log files streams will remain opened after silc_log_set_file()
577 call, means less CPU usage notably on high traffic servers.
578 File streams are now full buffered, and flushed to the disk
579 every 5 minutes, lesses HD activity and CPU usage.
580 Messages can be redirected, allowing admins to configure
581 one single logfile for all server messages.
582 the silc_log_quick global variable to activate fast-logging.
583 Affected files lib/silcutil/silclog.[ch]
585 * Changed some code to conform new silclog APIs. Affected
586 files are doc/example_silcd.conf.in, silcd/server.c
587 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
590 * Fixed a memory leak that could occur in some situations.
591 Affected file silcd/serverconfig.c.
593 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
595 * Added the silc_client_del_client to remove the client from
596 all channels as well. Affected file lib/silcclient/idlist.c.
598 * Fixed the client library to correctly remove the client
599 from all channels when the client entry is being destroyed.
600 Affected file lib/silcclient/client_notify.c, command.c.
602 * Added auto-nicking support to the client library. If the
603 applicatio now sets client->nickname it will be sent to the
604 server after connecting by the library. This way for example
605 SILCNICK (or IRCNICK) environment variables will have effect
606 and always change the nickname automatically to whatever
607 it is wanted. Affected file lib/silcclient/client.[ch].
609 * Renamed silc_server_command_bad_chars to the
610 silc_server_name_bad_chars and moved it to the
611 silcd/server_util.[ch]. Added also new function
612 silc_server_name_modify_bad to return nickname that
613 includes bad characters as new nickname without those
614 bad characters. This check and modify is now used in
615 silc_server_new_client when the username is initially set
616 as nickname, so it must be checked to be valid nickname.
617 Affected file silcd/packet_receive.c.
619 * The nickname length is now taken from the packet for real
620 and not trusted to strlen() since it clearly can return
621 wrong length for nickname including bad characters. This
622 also applies to channel names. Affected file silcd/command.c.
624 * Removed the lib/silcsilm/modules directory. Modules are now
625 compiled into the lib/silcsim. Fixed the copying of the
626 modules to follow symbolic links in Makefile.am.pre.
628 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Fixed silc_string_regexify list creation. Fixes bugs with
631 BAN and INVITE commands in server. The affected file is
632 lib/silcutil/unix/silcunixutil.c.
634 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Removed the command destructor entirely from the server's
637 command and command reply routines. It is not needed, and
638 its usage was buggy and caused crashes. Affected files are
639 silcd/command[_reply].[ch].
641 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Cancel protocol and NULL sock->protocol if timeout
644 occurred during protocol. Affected file silcd/server.c.
646 * Cancel protocol timeouts always before calling the final
647 callback, to assure that after final callback is called
648 no other state will be called for the protocol anymore.
649 Affected file silcd/protocol.c.
651 * Print error log if incoming connection configuration could
652 not be found. Affected file silcd/server.c.
654 * Fixed JOIN command to correctly save the founder mode
655 to the client on normal SILC server, when the channel
656 was created by the router. Affected file silcd/command.c.
658 * Fixed LIST command (hopefully) to send correct reply
659 packets. Affected file silcd/command.c.
661 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
663 * The silc_packet_receive_process now returns FALSE if the
664 read data was invalid packet, and TRUE if it was ok.
666 The server now checks that if unauthenticated connection
667 sends data and its processing fails the server will close
668 the connection since it could be a malicious flooder.
670 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
672 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Make sure the warning about error opening a log file is
675 printed only once and not everytime it fails (produces
676 too much useless log). Affected file lib/silcutil/silclog.c.
678 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
680 * Made the silc_server_daemonise() function more readable.
681 Affected file silcd/server.c.
683 * Pid file is now optional, the user may comment it out from
684 the config file. Removed define SILC_SERVER_PID_FILE, we
685 don't need a default any longer. Affected file
686 configure.in.pre, lib/Makefile.am.pre.
688 * Make some use of the pid file. The server now dies at startup
689 if it detects a valid pid file on his path. The server would
690 die anyway in this circumstance, because of the bind() failure.
691 Affected file silcd/silcd.c.
693 * No longer compiling lib/dotconf.
695 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Fixed JOIN command parsing not to crash. Affected file
698 lib/silcclient/command.c.
700 * Fied the NICK_CHANGE notify to add the new client entry
701 even it is resolved. This removes an <[unknown]> nick
702 thingy bug in the client. Affected file is
703 lib/silcclient/client_notify.c.
705 * Do not try to allocate 0 bytes (efence does not like it)
706 in lib/silccore/silccomand.c when encoding payload.
708 * Do not take IRCNICK as nickname in Irssi SILC client since
709 it is not possible to set nickname before hand connecting
710 the server (TODO has an entry about adding auto-nicking
713 * Changed the silc_server_command_pending to check whether
714 there already exists an pending entry with the specified
715 command, command identifier and pending callback. This is
716 to fix IDENTIFY and WHOIS related crashes that may register
717 multiple pending commands with same identifier. Affected
718 file silcd/command.c.
720 * Fixed the server to reconnect to the router even if it
721 was already reconnecting and EOF was received. This to
722 fix a possibility that the server wouldn't ever try to
723 auto-reconnect to the router. Affected file silcd/server.c.
725 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Fixed the server's password authentication to use the
728 length of the locally saved password, and not the one
729 sent in the packet. Affected file silcd/protocol.c.
731 * Fixed same password authentication problem in the
732 Authentication Payload handling routines in
733 lib/silccore/silcauth.c.
735 * Yet another password authentication problem fixed with
736 channel password handling in silcd/command.c.
738 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
740 * If first character of string in silc_parse_userfqdn is '@'
741 then do not parse it. Affected file is
742 lib/silcutil/silcutil.c.
744 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Fixed minor bug in IDENTIFY command reply sending, which
747 caused various weird problems during JOIN when it was
748 resolving names for users. Affected file silcd/command.c.
750 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Fixed the IDENTIFY command reply sending to chech better valid
753 clients. It was possible to send incomplete list of replies.
754 Affected file silcd/command.c.
756 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
758 * Added silc_client_command[s]_[un]register functions now to
759 dynamically register the commands in client library. Removed
760 the static table of commands. This allows the client library
761 to call commands without causing the application to know about
762 what commands library has called.
764 Removed the INFO command reply kludge to detect when the command
765 was called by library. Now library use its own command reply
766 function for INFO command.
768 Added function silc_client_command_call to call a command.
769 Application can use it to call command, not access the structure
772 Now all commands that are sent by the client library (not
773 explicitly sent by application) use own command reply functions.
775 Affected files around lib/silcclient/ and in
776 irssi/src/silc/core/.
778 * Fixed the WHOIS command reply sending to chech better valid
779 clients. It was possible to send incomplete list of replies.
781 Fixed the WHOIS and IDENTIFY to send the request to router
782 if normal server did not do it and did not find any results.
784 Affected file silcd/command.c.
786 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Moved the internal data from SilcClient context into its
789 own file, not accesible to application. Affected files
790 lib/silcclient/client.h and lib/silcclient/client_internal.h,
791 and other files in client library.
793 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
795 * Added doc/examples installation target in Makefile.am.pre.
798 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
800 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
801 commands the found client entry will be removed from the
802 cache, after notifying application about the error. Affected
803 file lib/silcclient/command_reply.c.
805 * Changed the /MSG to check for exact nickname user gave, and
806 not let `nick' match `nick@host' if it is only one found. Now,
807 user must type the exact nickname (like nick@host2) even if
808 there are no more than one same nicks found. This is to avoid
809 a possibility of sending nickname to wrong nickname since
810 `nick' could match `nick@host'. Affected file is
811 irssi/src/core/silc-servers.c.
813 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Do not print "you are now server operator" or similar when
816 giving /away command. Affected files are
817 irssi/src/silc/core/client_ops.c, silc-servers.h.
819 * Made the silc_server_command_pending_error_check to send
820 the same command reply payload it received back to the
821 original sender of the command. This way all arguments
822 that was received by the server will be received by the
823 client too. Affected file silcd/command.c.
825 * Added the silc_idcache_add to return the created cache entry
826 to a pointer. Affected file lib/silccore/silcidcache.[ch].
828 * Add global clients to expire if they are not on any channel.
829 This is because normal server will never know if they signoff
830 if they are not on any channel. The cache expiry will take
831 case of these entries. This is done by normal servers only.
832 The affected files are silcd/command_reply.c,
833 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
835 * If server receives invalid ID notification for WHOIS or
836 IDENTIFY and the ID exists in the lists, it is removed.
837 Affected file silcd/command_reply.c.
839 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
840 in client then client entry that it matches is searched and
841 the nickname is printed on the screen for user. Affected
842 file irssi/src/silc/core/client_ops.c.
844 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Use cache entry expire time in the LIST command reply to
847 purge old entries from the cache after the LIST command
848 reply has been received. This way we don't have non-existent
849 entries in the cache for too long. Affected file is
850 silcd/command_reply.c.
852 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
854 * If we are normal server, and we've not resolved client info
855 in WHOIS or IDENTIFY from router, and it is global client,
856 we'll check whether it is on some channel. If it is not
857 then we cannot be sure about its validity and will resolve it
858 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
859 file silcd/command.c.
861 * Search channel by name (if possible) rather than by ID
862 in IDENTIFY command's command reply. Affected file is
863 silcd/command_reply.c.
865 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Distribute to the channel passphrase in CMODE_CHANGE notify.
868 Updated specs and implemented it. Affected file silcd/command.c,
869 silcd/packet_send.c and silcd/packet_receive.c.
871 * Implemented the <founder auth> payload handling in the JOIN
872 command. If provided all conditions for channel joining
873 except requirement to provide correct passphrase can be
874 overrided by the channel founder. Updated the protocol specs.
875 Affected file silcd/command.c.
877 Added support for founder auth in JOIN command in client
878 library. Fixed the parsing of the JOIN command now to support
879 all options as they should be. The affected file is
880 lib/silcclient/command.c.
882 * Optimized the WHOIS and IDENTIFY commands to send the request
883 to router only if it includes nicknames or other names. If
884 they include only IDs then check the local cache first before
885 routing. Affected file is silcd/command.c.
887 * Added channels topic announcements. Affected file is
888 silcd/packet_receive.c and silcd/server.c.
890 * Fixed the silc_server_send_notify_topic_set to really destine
891 the packet to channel. Affected file silcd/packet_send.c.
893 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
894 library. Affected file lib/silcclient/client_notify.c.
896 * Added UMODE announcements. Affected file silcd/server.c.
898 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Memory leak fixes in:
902 lib/silcutil/silcsockconn.c
903 lib/silcske/silcske.c
906 lib/silccrypt/silcpkcs.c
907 lib/silccore/silccommand.c
908 lib/silccore/silcidcache.c
913 * ROBOdoc documented the lib/silcske/groups.h file and a
914 bit changed the interface for better.
916 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
918 * Update the client entry context in the ID cache after
919 nick change. Affected file lib/silcclient/command.c.
920 Fixes the CUMODE command when regaining founder privileges,
921 and a little WHOIS problem.
923 * Fixed silc_net_gethostbyname to correctly call the
924 inet_ntop. Affected file lib/silcutil/silcnet.c.
926 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
928 * Added IPv6 support checking to the configure.in.pre, added
929 also --enable-ipv6 option to override the check. Affected
930 file configure.in.pre.
932 * The silc_thread_create now calls the start function
933 directly if threads support is not compiled in. Removes
934 ugly #ifdef's from generic code. Affected files are
935 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
937 * Added silc_net_gethostby[name/addr]_async to asynchronously
938 resolve. Affected files are lib/silcutil/silcnet.[ch].
940 * Added support for rendering IPv6 based server, client and
941 channel IDs. Affected file lib/silcutil/silcutil.c.
943 * Added support for creating IPv6 based server IDs. Affected
944 file is silcd/serverid.c.
946 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
948 * Added silc_net_gethostby[addr/name] into the
949 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
950 routines. Added silc_net_is_ip[4/6]. Affected file is
951 lib/silcutil/unix/silcunixnet.c. All routines that take
952 address as argument now supports both IPv4 and IPv6 addresses.
954 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
956 * Fixed LIST command reply sending in server. Affected file
959 * Server now sends the kicker's client ID in the KICK notify
960 to the kicked client. Affected file silcd/command.c.
962 * The client library now parses the kickers client ID and
963 UI displays it. Affected files lib/silcclient/client_notify.c
964 and irssi/src/silc/core/silc-channels.c, module-formats.c.
966 * Made all payload parsing function prototypes consistent.
967 They all take now const unsigned char * and uint32 pair as
968 the payload data instead of SilcBuffer. Changes all around
969 the source tree. Other unsigned char* -> const unsigned char*
970 changes around the tree as well.
972 * Optimized SFTP client and server packet sending not to
973 allocate new buffer for each packet but to recycle the
974 first allocated buffer. Affected files are
975 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
977 * Optimized the SFTP client to use SilcList instead of
978 SilcDList for requests, because it is faster. Affected file
979 is lib/silcsftp/sftp_client.c.
981 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
982 into lib/silccore/silcid.[ch].
984 Renamed silcpayload.[ch] into silcargument.[ch].
986 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
988 * If client entry is deleted with active key agreement
989 session, abort the session.
991 The silc_client_abort_key_agreement now calls the completion
992 callback with new SILC_KEY_AGREEMENT_ABORTED status.
994 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
997 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Don't use __restrict in older GCC's. Affected file is
1000 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1002 * silc_net_localhost now attempts to reverse lookup the
1003 IP/hostname. Affected file lib/silcutil/silcnet.c.
1005 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1006 command. It can be used to gain founder privileges at
1007 the same time when joining the channel.
1009 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1010 kicker's client ID as well. Updated protocol specs.
1012 Defined that the server must send SILC_COMMAND_IDENTIFY
1013 command reply with error status to client who sent
1014 private message with invalid client ID.
1016 Updated the protocol specification.
1018 * Added silc_server_send_command_reply to send any
1019 command reply. Affected file silcd/packet_send.[ch].
1021 * Added silc_id_payload_encode_data to encode ID payload
1022 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1024 * The server now send IDENTIFY command reply with error
1025 status if client ID in private message is invalid. Affected
1026 file silcd/packet_receive.c.
1028 * Save the server key file with server's IP address in
1029 the filename instead of hostname. The affected file is
1030 irssi/src/silc/core/client_ops.c.
1032 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1037 * Added libtool support for compiling shared objects in
1038 lib/silcsim. Affected file configure.in.pre and
1039 lib/silcsim/Makefile.am. Original patch by cras.
1041 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Pid file configuration, and server's config file fixes
1044 patch by toma. Updated CREDITS file.
1046 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Fixed silc_client_channel_message to not try to decrypt
1049 the message twice if it resolved the destination client
1050 information. This could cause of dropping one channel
1051 message. Affected file lib/silcclient/client_channel.c.
1053 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1056 lib/silcclient/client.c. This function is used when the SILC
1057 Client is run under some other scheduler, or event loop or
1058 main loop. On GUI applications, for example this may be
1059 desired to used to run the client under the GUI application's
1060 main loop. Typically the GUI application would register an
1061 idle task that calls this function multiple times in a second
1062 to quickly process the SILC specific data.
1064 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1066 * Fixed silc_server_drop() for dropping the supplementary
1067 groups as well, this could cause a security hole on some
1070 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1072 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1075 * Write PID file after dropping privileges. Added -F option
1076 to run server on foreground. A patch by debolaz.
1077 Affected files silcd/server.c, silcd/silcd.c.
1079 * Fixed MOTD to return the MOTD file server name. Affected
1080 file silcd/command.c.
1082 * Added INFO command reply handling to the Irssi SILC Client.
1083 Affected file irssi/src/silc/core/client_ops.c.
1085 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Fixed the silc_idcache_list_* routines to really support
1088 the dynamic list. Fixes a crash. Affected file is
1089 lib/silccore/silcidcache.c.
1091 * Fixed the LIST command reply to really call LIST command's
1092 pending callbacks. Affected file silcd/command_reply.c.
1094 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Update conn->local_entry->nickname after giving NICK
1097 command. Affected file lib/silcclient/command.c.
1099 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1101 * Added the [pid] option to the silcd configuration file
1103 Affected files: serverconfig.[ch] and silcd.c
1105 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Save fingerprint in WHOIS command reply in server.
1108 Affected file silcd/command_reply.c.
1110 * Fixed NICK commands pending callback registration.
1111 Affected file lib/silcclient/command.c.
1113 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Use ++server->cmd_ident when sending commands in server,
1116 instead of random number. Affected file silcd/command.c.
1118 * Fixed GETKEY command reply to call actually GETKEY pending
1119 command callbacks. Affected file silcd/command_reply.c.
1121 * A bit stricter check for nicknames. Check for same nickname
1122 in NICK command also. Affected file silcd/command.c.
1124 * Do not call INFO command everytime client ID changes, only
1125 during first connecting. Affected file lib/silcclient/client.c.
1127 * Set the new nickname only after successful command reply for
1128 NICK command is returned by server. Affected file
1129 lib/silcclient/command.c.
1131 * Remove nicknames from nicklist during server_signoff notify.
1132 Should fix /NAMES bit more. The affected file is
1133 irssi/src/silc/core/silc-channels.c.
1135 * Added `fingerprint' field to the SilcIDListData in the
1136 silcd/idlist.h to hold the fingerprint of the client's
1139 Send the fingerprint of the client's public key in WHOIS
1142 Affected files silcd/command.c, and silcd/idlist.[ch].
1144 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1145 create fingerprint from given data.
1147 * Show the fingerprint of the client's public key in WHOIS.
1148 Affected files irssi/src/module-formats.[ch] and
1149 irssi/src/silc/core/client_ops.c.
1151 * Format the multiple same nicknames also during JOIN and
1152 NICK_CHANGE notifys. Affected file is
1153 lib/silcclient/client_notify.c.
1155 * Do not print error on screen for invalid private message
1156 payload since it can come if someone is sending private
1157 messages with wrong key. Affected file
1158 lib/silccore/silcprivate.c.
1160 * Fixed multiple concurrent /PING crash. Affected file
1161 lib/silcclient/command.c.
1163 * Changed the wrong ID encoding. All IP addresses must be
1164 in MSB first order in encoded format. They were encoded
1165 wrong and was in LSB format. Affected files are
1166 silcd/serverid.c, lib/silcutil/silcutil.c.
1168 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1170 * Call the `connect' client operation through the scheduler
1171 in case of error. Affected file lib/silcclient/client.c.
1173 * Call the `failure' client operation even if the error
1174 occurred locally during a protocol. Affected file is
1175 lib/silcclient/protocol.c.
1177 * Added support of sending LIST command to router from normal
1178 server. This way normal server can get list of all channels
1179 in the network too. Fixed the channel list sending in the
1180 server too. Affected files are silcd/command.c, and
1181 silcd/command_reply.[ch].
1183 * Added silc_server_update_channels_by_server and
1184 silc_server_remove_channels_by_server. They are used during
1185 disconnection of primary router and in backup router protocol.
1186 Affected file silcd/server_util.[ch], silcd/server.c and
1187 silcd/server_backup.c.
1189 * Fixed channel adding to global list in IDENTIFY command
1190 reply in server. Affected file silcd/command_reply.c.
1192 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * If the incoming packet type is REKEY or REKEY_DONE process
1195 that packet always synchronously. Fixes yet another MAC
1196 failed error on slow (dialup) connections. Affected file
1197 lib/silcclient/client.c and silcd/server.c.
1199 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Call check_version SKE callback for initiator too. Affected
1202 file lib/silcske/silcske.c.
1204 * Implemented fix for security hole found in the SKE that was
1205 fixed in the specification few days back; the initiator's
1206 public key is now added to the HASH value computation.
1207 Added backwards support for the old way of doing it too, for
1208 old clients and old servers. Affected file is
1209 lib/silcske/silcske.c.
1211 * Enabled mutual authentication by default in SKE. If initiator
1212 is not providing mutual authentication the responder will
1213 force it. This will provide the proof of posession of the
1214 private key for responder. The affected files are
1215 lib/silcclient/protocol.c and silcd/protocol.c.
1217 * Do not cache anymore the server's public key during SKE.
1218 We do mutual authentication so the proof of posession of
1219 private key is done, and if the server is authenticated in
1220 conn auth protocol with public key we must have the public
1221 key already. Affected file silcd/protocol.c.
1223 * Added new global debug variable: silc_debug_hexdump. If
1224 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1225 file lib/silcutil/silclog.[ch].
1227 * Fixed compilation warning due to char * -> const char *.
1228 Affected files lib/silcutil/silcnet.h, and
1229 lib/silccore/silcauth.[ch].
1231 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Fixed CMODE command when new channel key was created. If
1234 the creation failed the old key was removed. Next time giving
1235 same command would crash the server since the old key was
1236 freed already. Affected file silcd/command.c.
1238 * Fixed the silc_server_announce_get_channels to not crash
1239 on reconnect. Affected file silcd/server.c.
1241 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Added silc_log_set_debug_string function to set a regex
1244 string to match for debug output. Only the function names,
1245 or filenames matching the given debug string is actually
1246 printed. This way it is possible to filter out those debug
1247 strings that user is not interested in.
1249 Fixed a bug in silc_string_regexify.
1251 Affected files lib/silcutil/silclog.[ch], and
1252 lib/silcutil/unix/silcunixutil.c.
1254 * Changed the -d options in both server and Irssi SILC client
1255 to take the debug string as argument. Affected files
1256 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1258 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Added silc_hash_babbleprint to create a Bubble Babble
1261 Encoded fingerprint. The encoding is developed by Antti
1262 Huima (draft-huima-babble-01.txt), and it creates human
1263 readable strings out of binary data. Affected file
1264 lib/silccrypt/silchash.[ch].
1266 * Print the babble print now in addition of fingerprint as well
1267 in Irssi SILC client. Affected files are
1268 irssi/src/fe-common/silc/module-formats.[ch],
1269 irssi/src/fe-common/silc/core/client_ops.c.
1271 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Fixed a security problem found in SKE. The initiator's
1274 public key too is now added to the HASH hash value creation
1275 which is signed by the responder to create the SIGN value.
1276 This will prevent anyone in the middle to lie to the responder
1277 about the initiator's public key. If this is done now, the
1278 man in the middle will get caught. Updated the protocol
1281 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Better installation directory handling. Configure module
1284 paths and other paths automatically to example_silc* files
1285 in doc/. A patch by toma.
1287 * Fixed compiler warning from MPI library, and from SILC RNG.
1290 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1291 It can be configured with ./configure. A patch by toma.
1293 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Find correct make to use in prepare-clean. A patch by
1296 toma. Affected file prepare-clean.
1298 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1300 * Added irssi variables use_auto_addr, auto_bind_ip,
1301 auto_bind_port and auto_public_ip.
1303 * Changed the interface for silc_client_send_key_agreement
1304 in lib/silcclient/silcapi.h
1308 irssi/src/silc/core/silc-core.c
1310 lib/silcclient/silcapi.h
1311 irssi/src/silc/core/silc-channels.c
1312 lib/silcclient/client_keyagr.c
1315 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Added silc_pkcs_public_key_compare to compare two
1318 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1320 * Check that the client who set the founder mode on the
1321 channel is the same client that is giving the founder
1322 mode to itself. It is done by comparing the saved public
1323 key (it is saved even in the authentication is passphrase).
1324 Affected file silcd/command.c.
1326 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Do not process packet for disconnected socket connection.
1329 Affected file lib/silccore/silcpacket.c.
1331 * Process the DISCONNECT packet through scheduler in the
1332 client library. Affected file lib/silcclient/client.c.
1334 * Fixed the silc_client_packet_parse to not to increase
1335 the packet sequence number if the conn->sock and the
1336 current socket connection is not same. This can happen
1337 for example during key agreement when the conn includes
1338 multiple socket connections (listeners). Affected file
1339 lib/silcclient/client.c.
1341 * The sender of the file transfer request now provides also
1342 the pointer (listener) for the key exchange protocol. If
1343 the listener cannot be created then it sends empty key
1344 agreement and lets the receiver provide the listener.
1346 Added `local_ip' and `local_port' arguments to the
1347 silc_client_file_send. If they are provided they are used,
1348 if not then it will attempt to find local IP address, if
1349 not found or bind fails then the remote client will provide
1352 Affected files are lib/silcclient/client_ftp.c and
1353 lib/silcclient/silcapi.h.
1355 * Extended the FILE SEND command to support defining the
1356 local IP and port for key exchange listener. They are
1357 optional. Affected file irssi/src/silc/core/silc-servers.c.
1359 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Defined to WHOIS command reply the sending of fingerprint
1362 of the client's public key (if the proof of posession of the
1363 corresponding private key is verified by the server).
1364 Updated to the protocol specification.
1366 * Added support of receiving the client's public key's
1367 fingerprint in command reply in client library. Affected
1368 file is lib/silcclient/command_reply.c, and
1369 lib/silcclient/idlist.[ch].
1371 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Do not send over 128 chars long nickname to the server
1374 in NICK command. Affected file lib/silcclient/command.c.
1376 * Do not send over 256 chars long channel names to the server
1377 in JOIN command. Affected file lib/silcclient/command.c.
1379 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Assure that silc_server_close_connection cannot be called
1382 twice for same socket context. Affected file is
1385 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Send error message to application if opening file for
1388 writing during file transfer fails. Affected file is
1389 lib/silcclient/client_ftp.c.
1391 Remove all file transfer sessions for a client that we're
1392 removing from ID cache.
1394 Affected file is lib/silcclient/client_ftp.c.
1396 * Fixed silc_net_addr2bin to return correct address. Affected
1397 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1399 * Fixed file transfer session removing on signoff notify.
1400 Affected file irssi/src/silc/core/silc-servers.c.
1402 * Added the SilcClientFileError to be returned in the monitor
1403 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1404 Affected file lib/silcclient/silcapi.h.
1406 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Fixed a crash in silc_client_ftp_free_sessions and
1409 silc_client_ftp_session_free_client. Affected file
1410 lib/silcclient/client_ftp.c.
1412 * Added `disabled' field in the SilcChannelEntry in the server
1413 to indicate if the server entry is disabled. Affected file
1414 silcd/idlist.h, silcd/command[_reply].c.

1423 * Fixed a crash in client resolving in client_prvmsg.c in
1424 client library. Affected file lib/silcclient/client_prvmsg.c.
1426 * Do not actually remove the client directly from ID cache
1427 during SERVER_SIGNOFF, but invalidate it. This way we
1428 preserve the WHOWAS info for the client. Affected file
1429 silcd/server_util.c.
1431 * Fixed SERVER_SIGNOFF notify handling in the server. The
1432 server is now able to process incoming SERVER_SIGNOFF notify
1433 for a server that it doesn't even know about. It will remove
1434 the clients provided in the notify. Affected file
1435 silcd/packet_receive.c.
1437 * Check for partial packet in data queue after every packet that
1438 was found from the queue. Return and wait for more data if
1439 there is partial data in queue. Affected file is
1440 lib/silccore/silcpacket.c.
1442 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Added SilcClietFileError enum to indicate error in
1445 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1446 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1447 Affected files lib/silcclient/silcapi.h and
1448 lib/silcclient/client_ftp.c.
1450 * Check that newsize in silc_buffer_realloc is larger than
1451 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1453 * Added better monitor of file transfers. It now monitors
1454 key agreement protocol during the file transfer too. Added
1455 error reporting too. Affected files
1456 irssi/src/silc/core/silc-servers.c,
1457 irssi/src/fe-common/silc/module-formats.[ch].
1459 * Wrote a help file for FILE command.
1461 * Added silc_rng_global_get_byte_fast to get not-so-secure
1462 random data as fast as possible. Random data is read from
1463 /dev/urandom if available and from the SILC RNG if not
1464 available. It is used in padding generation. Affected file
1465 lib/silccrypt/silcrng.[ch].
1467 * All packets in client library are now processed synchronously.
1468 Optimized packet processing a lot. Affected file
1469 lib/silcclient/client.c.
1471 * All server connection packets are processing synchronously
1472 now in server, to optimize packet processing. Affected file
1475 * Include files are installed now only in Toolkit distribution
1476 if make install is given. Affected files: all Makefile.am's.
1478 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Assure that silc_client_notify_by_server_resolve does not
1481 resolve the client information multiple times. If it cannot
1482 be found by the first it cannot be found at all. Affected
1483 file lib/silcclient/client_notify.c.
1485 * Fixed WHOWAS command reply calling. Affected file
1486 lib/silcclient/command_reply.c.
1488 * Removed all references to silc_idlist_get_client from the
1489 Irssi SILC client since that call is internal call used by
1490 the library. The Irssi SILC client will use now client
1491 retrieval functions found in silcapi.h.
1493 * Fixed a bug in resolving nickname info before sending
1494 private message. It used freed memory. Affected file
1495 irssi/src/silc/core/silc-servers.c.
1497 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Assure my_channels statistics cannot go negative in server.
1500 Affected files silcd/server.c, silcd/server_util.c.
1502 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1506 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1512 lib/sftp/sftp_fs_memory.c.
1514 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Added silc_net_localip to return local host's IP address.
1517 Affected file lib/silcutil/silcnet.[ch].
1519 * If key exchange or rekey protocol is active for a connection
1520 parse all packets syncronously since there might be packets
1521 in packet queue that we are not able to process without first
1522 processing packets before them. Affected file silcd/server,
1523 lib/silcclient/client.c.
1525 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1526 whether library should continue processing the packet.
1527 Affected file lib/silccore/silcpacket.h.
1529 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1530 SilcSFTPMonitorData to SFTP server to monitor various
1531 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1532 lib/silcsftp/sftp_server.c.
1534 * Added silc_file_size to return file size. Affected file

1539 transmission. Affected file lib/silcclient/client_ftp.c,
1540 lib/silccilent/client.[ch].
1542 * Added new local command FILE to the Irssi SILC Client.
1543 It is used to perform the file transfer. It has subcommands
1544 SEND, RECEIVE, SHOW and CLOSE. Affected files
1545 irssi/src/silc/core/client_ops.c,
1546 irssi/src/silc/core/silc-server.[ch].

1555 * Renamed silc_file_read and silc_file_write to functions
1556 silc_file_readfile and silc_file_writefile. Added function
1557 silc_file_open and silc_file_close. Affected files
1558 lib/silcutil/silcutil.[ch].
1560 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Resolve the client info when received private message or
1563 channel message for a client which nickname we don't know.
1564 Affected files lib/silcclient/client_prvmsg.c and
1565 lib/silcclient/client_channel.c.
1567 * Do not crash in /KEY if client is not connected. Affected

1570 * Added SilcClientStatus field to the SilcClientEntry in the
1571 lib/silcclient/idlist.h.
1573 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1574 is incomplete and is being resolved, it won't be resolved
1577 Make sure also that USERS command reply does not resolve
1578 twice information. Affected file is
1579 lib/silcclient/command_reply.c.
1581 Make sure that silc_client_get_clients_by_list does not
1582 resolve twice same information.
1584 * Check for valid client->id in the silc_server_free_client_data.
1585 Affected file silcd/server.c.
1587 * Fixed /GETKEY nick@server not to crash if the server entry
1588 is not found. Affected file lib/silcclient/command.c.
1590 * Fixed the silc_server_check_cmode_rights to check the
1591 requested modes correctly. Affected file silcd/command.c.
1593 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Better checks for non-printable chars in nick added.
1596 Affected file silcd/command.c.
1598 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Call the silc_server_udpate_servers_by_server in the
1601 primary router that comes back online in the backup resuming
1602 protocol. Otherwise it routes packets wrong. Affected file
1603 silcd/server_util.[ch], silcd/server_backup.c.
1605 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1608 lib/silcutil/silcbuffmt.[ch].
1610 * Redefined the SILC packet header to include the padding
1611 length. Affected file lib/silccore/silcpacket.[ch].
1613 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1614 length for maximum padding up to 128 bytes). Affected
1615 file lib/silccore/silcpacket.h.
1617 * Removed all backwards support for old 0.5.x MAC thingies.
1618 The SILC packet header change makes it impossible to be
1619 backwards compatible.
1621 * Send the ENDING packet with timeout in the backup resuming
1622 protocol. This is to assure that all routers has connected
1623 to the primary router. Affected file silcd/server_backup.c.
1625 * Changed the RNG to take the first IV from random data. It
1626 used to take it from zero actually. Changed the RNG also
1627 to use /dev/urandom during session. /dev/random is used
1628 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1630 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Changed the SILC packet header to have the first two bytes
1633 (the packet length) encrypted. Affected files aroung the
1634 code tree, lib/silccore/silcpacket.[ch]. Removed the
1635 SilcPacketCheckDecrypt callback. It is not needed anymore
1636 since the silc_packet_receive_process will determine now
1637 whether the packet is normal or special.
1639 * Implemented the unidirectional MAC keys. Affected files
1640 lib/silcske/silcske.c, silcd/protocol.c and
1641 lib/silcclient/protocol.c.
1643 * Implemented the packet sequence number to the MAC computation.
1644 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1645 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1646 lib/silcclient/protocol.c.
1648 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Allow backup router to announce servers. All servers
1651 announced by backup router are added to the global list
1652 automatically. Update hte server's socket to our primary
1653 router also when backup router announces a server.
1654 Affected file silcd/packet_receive.c.
1656 * Do not update the client->router in the function
1657 silc_server_udpate_clients_by_server if the client is on
1658 global list. We might fail to find any specific server
1659 for locally connected clients and local cell clients. They
1660 should still use the `from' and not `to' as client->router.
1661 This fixes backup router resuming protocol. Affected file
1662 silcd/server_util.c.
1664 * Decrease channel statistics count only if the channel
1665 deletion worked. Affected files are silcd/server.c and
1666 silcd/server_util.c.
1668 * Added silc_server_update_servers_by_server to update origin
1669 of all server entries. Used during backup router protocol.
1670 Affected files silcd/server_util.[ch], silcd/server.c. and
1671 silcd/backup_router.c.
1673 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1674 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1675 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1676 lib/silccrypt/silchmac.c.
1678 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Assure that router cannot reroute the same channel message
1681 to the sender. Affected file silcd/packet_receive.c.
1683 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Made better checks that the channel message is not sent
1686 to the router it came from. Affected file is
1687 silcd/packet_send.c. Fixed memory leak too.
1689 * Announce informations for incoming router connection, but
1690 only after checking if it is replaced by backup router.
1691 Affected file silcd/packet_receive.c.
1693 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Fixed the backup resuming protocol to work in multiple
1696 router environment. Affected file silcd/server_backup.c.
1698 * Route packet only to one router in the function
1699 silc_server_packet_send_to_channel. Affected file is
1700 silcd/packet_send.c.
1702 * Fixed silc_server_send_notify_dest to set the broadcast
1703 flag. Fixed the silc_server_send_notify_topic to actually
1704 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1705 Affected file silcd/packet_send.c.
1707 * Changed the SFTP Filesystem interface. Changed the
1708 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1709 the filesystem operation function. The SilcSFTPFilesystem
1710 is now a context that is allocated by all filesystem allocation
1711 functions and it already includes the operations structure
1712 and filesystem specific context. It is given as argument
1713 now to the silc_sftp_server_start. This made the interface
1714 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1715 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1717 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Changed the backup router adding and getting interfaces
1720 in the server. The router that will be replaced by the
1721 specified backup router is now sent as argument. Affected
1722 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1725 * Added silc_net_addr2bin_ne to return the binary form of
1726 the IP address in network byte order. Affected files
1727 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1729 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Check for existing server ID in silc_server_new_server
1732 and in silc_server_connect_to_router_final and remove the
1733 old entry if it exists. Affected file silcd/packet_receive.c,
1736 * Send the channel message always to only one router, either
1737 in upstream or downstream. Affected file is
1738 silcd/packet_send.c.
1740 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Wrote the definition of the backup resuming protocol to the
1743 protocol specification.
1745 * Removed one redundant channel key generation from normal
1746 server during joining procedure. Removed one redundant
1747 channel key sending from server to router during joining
1748 procedure. Affected file silcd/command.c.
1750 * Made minor bugfixes to the backup router resuming protocol.
1751 Affected file silcd/server_backup.c, server.c.
1753 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Added --disable-asm configuration option. Affected files
1756 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1759 * Implemented the backup resuming protocol that is used to
1760 resume the primary router position in the cell after the
1761 primary router comes back online. Affected files
1762 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1763 and silcd/server_util.[ch].
1765 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Sleep two (2) seconds after sending QUIT command to server.
1768 Affected file lib/silcclient/command.c.
1770 * Assure that if outgoing data buffer is pending do not force
1771 send any data. Affected file silcd/packet_send.c.
1773 * Assure that if outgoing data buffer is pending do not force
1774 send any data. Affected file lib/silcclient/client.c.
1776 * Implemented the backup router support when the primary router
1777 goes down. The servers and routers can now use the backup
1778 router as new primary router without loosing connectivity.
1780 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1783 in the server to indicate disabled entry. All data read
1784 from the connection will be ignored and no data is sent
1785 for entry that is disabled. Affected files are
1786 silcd/idlist.h, silcd/server.c.
1788 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Created SFTP client and server test programs in the
1791 lib/silcsftp/tests directory.
1793 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Implemented memory filesystem (virtual filesystem) for
1796 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1799 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Implemented the SFTP (SSH File Transfer Protocol) to the
1802 lib/silcsftp. It includes SFTP client and SFTP server
1805 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Moved lib/silccore/silcprotocol.[ch] to the
1808 lib/silcutil library.
1810 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1811 take variable argument list pointer as argument. Affected
1812 file lib/silcutil/silcbuffmt.[ch].
1814 * Added silc_buffer_set function that is used to set data
1815 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1816 Affected file lib/silcutil/silcbuffer.h.
1818 * Changed various routines in the core library to use the new
1819 silc_buffer_set instead of allocating new buffer only for
1822 * Added 64-bit value formatting and unformatting support to the
1823 silc_buffer_[un]format routines. Affected file is
1824 lib/silcutil/silcbuffmt.[ch].
1826 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1827 to includes/bitmove.h.
1829 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Fixed channel user mode saving in client library. Affected
1832 file lib/silcclient/command[_reply].c.
1834 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Defined the file transfer to the SILC Protocol. Added
1837 new packet type SILC_PACKET_FTP and defined File Transfer
1838 Payload. The mandatory file transfer protocol is SFTP
1839 (SSH File Transfer Protocol). Affected file in addition
1840 of the internet draft is lib/silccore/silcpacket.h.
1842 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1843 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1844 is used as part of backup router protocol when the primary
1845 router of the cell is back online and wishes to resume
1846 the position as primary router.
1848 * Redefined the MAC generation keys in the protocol. The
1849 same key is not used anymore in both direction. Both
1850 direction will now use different keys for sending and
1851 receiving. This fixes a potential security flaw. This
1852 change causes incompatibilities in the protocol.
1854 * Redefined also the MAC computation from the packet.
1855 An packet sequence number is now added to the MAC
1856 computation. This prevents possible replay attacks against
1857 the protocol. This change too causes incompatibilities
1860 Added `sequence' field to the SilcPacketContext to hold
1861 the current sequence number for the packet.
1863 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Added `created' field to the SilcIDListData in the file
1866 silcd/idlist.h to indicate the time when the entry was
1869 * Added `created' field to the SilcChannelEntry too. Affected
1870 file silcd/idlist.h.
1872 * Added `creation_time' aguments to all the announcement functions
1873 in the server. If it is provided then only the entries that
1874 was created after the provided time frame are actually
1875 announced. Affected file silcd/server.[ch].
1877 * The protocol says that the Channel ID's IP address must be
1878 based on the router's IP address. Added check for this in
1879 the silc_server_new_channel when processing incoming New Channel
1880 Payload. Affected file silcd/packet_receive.c.
1882 * Print out the correct version with --version in SILC client.
1883 Affected file irssi/src/silc/core/silc-core.c.
1885 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Fixed WHOWAS command to check for completnes of the client
1888 entry always, not just when the command is coming from client.
1889 Affected file silcd/command.c.
1891 * Added new function silc_server_packet_queue_purge to purge the
1892 outgoing data queue to the network. After the function returns
1893 it is guaranteed that the outgoing packet queue is empty.
1894 Affected file silcd/packet_send.[ch].
1896 * Purge the outgoing packet queue in the rekey protocol's final
1897 callback to assure that all rekey packets go to the network
1898 before quitting the protocol. Affected file silcd/server.c.
1900 * Added silc_client_packet_queue_parse as similar function as
1901 in server to the client library. The affected file is
1902 lib/silcclient/client.c.
1904 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Splitted silcd/server.c and created silcd/server_util.[ch]
1907 for utility functions.
1909 * Added new socket flag SILC_SF_DISABLED to indicate that the
1910 connection is open but nothing can be sent to or received from
1911 the connection. Affected file lib/silcutil/silsockconn.[ch].
1912 The checking for disabled socket is checked in the low level
1913 silc_socket_write and silc_socket_read functions.
1915 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Allow only nicknames and channel names that fits into the
1918 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1920 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * When processing JOIN command reply in server check that if
1923 the channel exists in our global list we'll move it the local
1924 list. Affected file silcd/command_reply.c.
1926 * Fixed the check whether client is joined on the channel already
1927 in JOIN command. Affected file lib/silcclient/command.c.
1929 * Fixed the JOIN command reply to check whether the channel
1930 already exists. Affected file lib/silcclient/command_reply.c.
1932 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Added silc_ske_status_string to map the SKE error numbers
1935 to readable strings. The affected files are
1936 lib/silcske/silcske[_status].[ch].
1938 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not show the private channels on the WHOIS channel list
1941 as it is not allowed by the protocol. The affected file is
1944 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Assure that the packet length digged from the actual packet
1947 is something sensible in the silc_packet_decrypt_rest_special
1948 in lib/silccrypt/silcpacket.c.
1950 * Free and NULL the allocated pointer in silc_hmac_alloc if
1951 the HMAC allocation fails. The affected file is
1952 lib/silccrypt/silchmac.c.
1954 * Print the selected security properties to the log files in
1955 the server. Affected file silcd/protocol.c.
1957 * Add SKE's reference counter even if calling the completion
1958 callback manually. Otherwise it goes negative, although it
1959 does not cause any problems. The affected file is
1960 lib/silcske/silcske.c.
1962 * Remove the client entry with short timeout after giving the
1963 KILL command. Affected file lib/silcclient/command.c.
1965 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1966 case all found clients are already disconnected (WHOWAS would
1967 found them) in the server. Affected file silcd/command.c.
1969 * Update the last_receive (time of last data received) to be
1970 updated only when received private or channel message so that
1971 the idle time showed in WHOIS makes more sense.
1973 * Added boolean field `valid' in to the SilcClientEntry in the
1974 client library to indicate whether the entry is valid or not.
1975 This fixes the nickname change bug on channel when changing
1976 the nickname to be same than the old (like nick to Nick) the
1977 nickname formatter doesn't set the new nick anymore to Nick@host.
1978 Affected file lib/silcclient/idlist.[ch].
1980 * Now actually fixed the nickname changing on disconnection.
1981 Added new function silc_change_nick to the Irssi SILC Client.
1982 Affected file irssi/src/silc/core/client_ops.c,
1983 irssi/src/silc/core/silc-nicklist.[ch].
1985 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Check that the public key exists in the GETKEY command before
1988 trying to encode it. Affected file silcd/command.c.
1990 * Print some notifications on received public keys with GETKEY
1991 command in the Irssi SILC Client. Affected files are
1992 irssi/src/fe-common/silc/module-formats.[ch],
1993 irssi/src/silc/core/client_ops.c.
1995 * Use IDENTIFY command to resolve the server information in the
1996 GETKEY command instead of INFO command. Affected file
1997 lib/silcclient/command.c.
1999 * All command reply functions in the client library now calls
2000 the pending command reply callbacks even if an error has
2001 occurred. The server has done this a long time and now it was
2002 time to move the client library to this as well. Now all
2003 errors can be delivered back to the pending command reply
2004 callbacks if necessary. Affected files are
2005 lib/silcclient/command[_reply].[ch].
2007 * Change the nickname on disconnection back to the username
2008 because in reconnect the server will enforce it to it anyway.
2009 Affected file irssi/src/silc/core/silc-servers.c.
2011 * Fixed a config file parsing bug in the Irssi SILC client.
2012 Affected file irssi/src/silc/core/clientconfig.c.
2014 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * When printing the channel mode on JOIN, verify that the
2017 channel key and channel's HMAC are valid. Affected file
2018 irssi/src/silc/core/client_ops.c.
2020 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2023 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2024 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2026 * Removed channel key rekey task deleting from the function
2027 silc_server_save_channel_key. Affected file silcd/server.c.
2028 Added explicit timeout task context instead that is used to
2029 delete the task if we are registering a new task before the
2030 new task has elapsed.
2032 * When channel key rekey occurs the client library now saves
2033 the old channel key for a short period of time (10 seconds) and
2034 is able to use it in case some is still sending channel
2035 messages encrypted with the old key after the rekey. Affected
2036 file lib/silcclient/[idlist.h|client_channel.c].
2038 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Added check to the silc_server_new_id_real to not accept
2041 new ID if it is the sender's own ID. Affected file is
2042 silcd/packet_receive.c.
2044 * Assure that we do not announce ourself or the one we've
2045 sending our announcements when we're router and are announcing
2046 servers to our primary router. Affected file silcd/server.c.
2048 * Fixed silc_server_command_identify_check_client to assemble
2049 correct WHOIS packet. It send corrupted WHOIS packet and
2050 caused problem with router to router connections. Affected
2051 file silcd/command.c.
2053 Fixed also silc_server_command_whois_check the same way
2054 as for the IDENTIFY command.
2056 * Added new SilcIDListStatus to the server in the SilcIDListData
2057 structure. The status now includes the current status of
2058 the entry (like registered, resolved etc.). Affected file
2059 silcd/idlist.[ch]. Defined a bunch of different status types
2060 as well. This replaced the old boolean registered field as well.
2062 Added resolve_cmd_ident field to the SilcClientEntry structure
2063 too so that if the entry is for example being resolved so
2064 another command may attach to the same pending command reply
2065 without requiring to resolve the same entry again. This concept
2066 should optimize the WHOIS and the IDENTIFY resolving under
2067 heavy load by taking away unnecessary resolving for entries
2068 that are being resolved already.
2070 Added support for adding multiple pending commands for one
2071 command idenfier. Affected file silcd/command[_reply].[ch].
2073 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2074 before deleting the data. Otherwise the hash table will have
2075 freed data in comparison functions. Affected file is
2076 silcd/command_reply.c.
2078 * Fixed silc_idlist_replace_client_id to add the new entry to
2079 the cache with NULL nickname. Otherwise there will be invalid
2080 memory as the nickname after the nickname is freed. Affected
2081 file silcd/packet_receive.c.
2083 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2084 saved into wrong slots because the previous number of entries
2085 was not taken into account. Affected file silcd/idlist.c.
2086 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2088 * If we are router and we receive JOIN notify to a channel that
2089 does not have any users then notified client is marked as the
2090 channel founder, as it is it. The affected file is
2091 silcd/packet_receive.c
2093 * Added to the extended hash table API's table_del_*ext functions
2094 the destructor as argument too, so that the caller can decide
2095 which destructor to use or whether to use destructor at all.
2096 Affected file lib/silcutil/silchashtable.[ch].
2098 * Fixed ID Cache purging. It actually deleted the entries from
2099 the hash table after the data was freed. The hash table ended
2100 up comparing freed memory. The affected file is
2101 lib/silccore/silcidcache.c.
2103 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Fixed Irssi SILC client's KILL command's HELP syntax.
2107 * The USERS command now resolves the detailed user information
2108 if the userinfo field is missing. Affected file is
2109 lib/silcclient/command_reply.c.
2111 * Do not print error in silc_file_read if the read file does
2112 not exist. Just silently return NULL. Affected file is
2113 lib/silcutil/silcutil.c.
2115 * Fixed the silc_log_output to not wine about NULL filename
2116 and to not create some bogus " " filename. Affected file is
2117 lib/silcutil/silclog.c.
2119 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Fixed various printing bugs on the user interface in the
2122 Irssi SILC Client. Minor changes that were forgotten from
2125 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Fixed the configure.in.pre and the compilation and distribution
2128 environment to support the new autoconf 2.52. That version is
2129 now required to compile the CVS trunk.
2131 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2134 to generally parse user@fqdn format strings. Affected file
2135 lib/silcutil/silcutil.c.
2137 * Added nickname_format and nickname_force_format fields to the
2138 SilcClientParams structure. The first one defines the format
2139 for the nicknames that the library will enforce if the receives
2140 multiple same nicknames. The second one is boolean value and
2141 can be used to force the library to always enforce the format
2142 to the nicknames regardles whether there are multiple nicknames
2143 or not. This configurable formatting was employed to flexibly
2144 support accessing multiple nicknames from the user interface.
2145 The userinterface can now set the nicknames to what ever format
2146 they prefer. Affected file lib/silcclient/silcapi.h.
2148 Added function silc_client_nickname_format to the file
2149 lib/silcclient/idlist.c. It performs the nickname formatting.
2151 Added new field `hostname´ to the SilcClientEntry context.
2152 It holds the hostname of the client. Affected file is
2153 lib/silcclient/idlist.h.
2155 * Irssi SILC Client sets the nicknames in nick@hostn format.
2156 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2157 irssi/src/silc/core/silc-core.c.
2159 The WHOIS printing now also shows both the real nickname and
2160 the formatted nickname so that user knows how to access the
2161 user if there are multiple same nicknames cached. Affected
2162 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2163 printing formatting too to take the hostname now as a separate
2164 argument. The Affected file is
2165 irssi/src/fe-common/silc/modules-formats.[ch].
2167 * Changed the silc_client_get_clients_local to accept the formatted
2168 nickname as argument. It accepts the real nickname too but the
2169 formatted nickname can be used to find the true entry from
2170 multiple entries. Affected file lib/silcclient/silcapi.h and
2171 lib/silcclient/idlist.c.
2173 * Added nickname_format_parse field to the SilcClientParams.
2174 It is a callback function provided by the application to parse
2175 the nickname out of the formatted nickname string. The library
2176 calls it to get the nickname from the formatted string. Since
2177 the application generally knows better the format of the nickname
2178 string it parses it instead of the library, even though library
2179 encodes the formatted string. If the callback function is not
2180 provided then the library will use the string as is. The
2181 affected file is lib/silcclient/silcapi.h.
2183 * All the nickname strings passed to the client library in
2184 commands are now expected to be formatted nickname strings.
2185 If the command does not support the formatted nickname string
2186 it will assume that the sent string is the actual nickname.
2187 Affected file lib/silcclient/command.c.
2189 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Added public key authentication support to OPER and SILCOPER
2192 commands in the client library. Affected file is
2193 lib/silcclient/command.c.
2195 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Changed the get_auth_methdod client operation to be asynchronous.
2198 It can be async if the application resolves the authentication
2199 method from the server during the negotiation. Added new
2200 SilcGetAuthMeth completion callback that the application will
2201 call after resolving the authentication method.
2203 Added function silc_client_request_authentication_method that
2204 the application can use to resolve the authentication method
2205 from the server. Added also SilcConnectionAuthRequest callback
2206 that the library will call after the server has replied. The
2207 application can call this function if it does not know the
2208 current authentication method.
2210 Affected files are lib/silcclient/client.c and
2211 lib/silcclient/silcapi.h.
2213 * The Irssi SILC client now automatically resolves the authentication
2214 method incase any configuration information is not present (and
2215 currently there never is). The affected file is
2216 irssi/src/silc/core/client_ops.c.
2218 * Fixed public key authentication from the client library.
2219 Affected file lib/silcclient/protocol.c. Changed also the
2220 protocol specification about the public key authentication in
2221 the connection authentication protocol. The actual data to be
2222 signed is now computed with a hash function before signing.
2224 * Fixed the public key authentication from the server as well.
2225 Affected file silcd/protocol.c.
2227 * Removed the mlock()'s from the memory allocation routines.
2228 Affected file lib/silcutil/silcmemory.c. The ./configure does
2229 not check anymore for the mlock(). Affected file is
2232 * Fixed USERS command in server to allow the execution of the
2233 command for private and secret channels if the client sending
2234 the command is on the channel. Affected file silcd/command.c.
2236 * Fixed silc_client_get_clients_local to return the clients
2237 count correctly. It could return wrong value. Affected file
2238 lib/silcclient/idlist.c.
2240 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2243 types. The assembler optimizations seemed not to like 64-bit
2244 data types. The assmebler optimizations thus are now enabled
2245 also for BSD systems as opposed to only enable them for Linux.
2247 * Do not check for threads at all on BSD systems. Affected
2248 file configure.in.pre.
2250 * Removed -n and -h options from the Irssi SILC Client since
2251 they are not used in silc.
2253 * Fixed the prime generation to assure that the first digit
2254 of the generated random number is not zero since our conversion
2255 routines does not like number strings that starts with zero
2256 digit. If zero digit is seen the random number is regenerated.
2257 This caused some corrupted RSA keys when the zero first digit
2258 was met. Affected file lib/silcmath/silcprimegen.c.
2260 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Fixed WIN32 configuration in the ./configure script.
2263 Fixed to include xti.h on environments that has it.
2264 Patches by Carsten Ilchmann and andrew.
2266 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Changed the silc_id_create_client_id to be collision
2269 resistant. It is now assured that there cannot be created
2270 two same client ID's. I suspect that some weird bugs in
2271 the server were actually caused by duplicate Client IDs.
2272 Affected file silcd/serverid.[ch]. A router receiving
2273 new ID now also assures and informs the sending server
2274 if the ID caused collision.
2276 * Changed the silc_id_create_channel_id to also assure that
2277 there are no collisions.
2279 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Statement about ignoring the Mutual Authentication flag when
2282 performing rekey with PFS was a bit misleading. It is ignored
2283 if it was set in the initial negotiation, it cannot be even
2284 set in the rekey. Fixed in the ke-auth draft. Started the
2285 new versions of the protocol drafts in the doc/.
2287 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Fixed a bug in silc_client_command_identify_save when saving
2290 new channel information. The channel name was no duplicated
2291 and caused crash on exit. Affected file is
2292 lib/silcclient/command_reply.c.
2294 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed the getkey command handling in the server. Send just
2297 empty OK reply to the sender if the key could not be fetched
2298 (but everything else was ok, like the key just was not available).
2299 Changed the public key parameter to optional in the protocol
2300 specs so that empty OK reply can be sent. Affected file
2303 Added a message to Irssi SILC client to tell to user if the
2304 server did not return a public key.
2306 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Fixed a channel key regeneration bug. It registered new
2309 timeout tasks exponentially until all system resources were
2310 used. Affected file silcd/server.c.
2312 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added the SILC Document generator to the scripts/silcdoc.
2315 It can be used to generate the Toolkit Reference Manual out
2316 of the source tree. Internally it will also use the RoboDoc
2317 generator now imported in util/robodoc.
2319 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Added couple of return's in rekey protocol if error orccurred
2322 during the protocol. The execution must be terminated.
2323 Affected file silcd/protocol.c. Also, terminate the protocol
2324 always with timeout.
2326 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * The client's Client ID was created initally from the wrong
2329 nickname (it could have been in format nick@host) in the
2330 silc_server_new_client. Affected file silcd/packet_receive.c
2332 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * Added some SILC_LOG_ERROR's to various error conditions
2335 if client could not be added to ID cache. Affected files
2336 silcd/packet_receive.c and silcd/server.c.
2338 * When client's sock->user_data is freed, NULL also the
2339 client->router and client->connection pointers. Added check
2340 for these pointers being NULL to various places around the
2341 code. Affected file silcd/server.c.
2343 * Added client->data.registered == TRUE checks to various
2344 places around the code to assure that unregistered client's
2345 are not handled when it is not allowed. Affected file
2348 * Added `bool registered' fields to all
2349 silc_idlist_[server|client]_get_* routines to indicate whether
2350 the fetched client needs to be registered or not. Affected
2351 file silcd/idlist.[ch].
2353 * Add your own entry as registered to the ID cache in the
2354 server. Affected file server.c.
2356 * Fixed a bug in silc_server_new_server. The SilcServer was
2357 set as the new server's context instead of SilcServerEntry.
2358 This naturally caused some weird bugs.
2360 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Do not delete the channel rekey task when adding it
2363 for in silc_server_create_channel_key.
2365 * Changed the silc_server_create_channel_key to return
2366 TRUE or FALSE to indicate the success of the channel key
2369 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Fixed MSVC++ project files and added missing files to
2372 Makefiles under win32/.
2374 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Do not add TCP_NODELAY flag if the operating system
2377 does not have it defined. Affected files are
2378 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2380 * Fixed buffer overflow from Irssi SILC Client. Affected
2381 file irssi/src/fe-common/core/themes.c.
2383 * Fixed double free in client library in the file
2384 lib/silcclient/client.c when disconnecting from server.
2386 * Applied double free patch from cras to Irssi SILC client.
2387 Affected files irssi/src/core/[modules/expandos].c
2389 * Fixed the disconnection handling to Irssi SILC Client.
2390 The application must call silc_client_close_connection
2391 in ops->connect client operation in case of failure of
2392 the connection. Affected file is
2393 irssi/src/silc/core/client_ops.c.
2395 * Do not set sock->protocol to NULL in the function
2396 silc_client_close_connection after executing the protocol's
2397 final callback since the sock might not be valid anymore.
2398 Affected file lib/silcclient/client.c.
2400 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Do not enable SILC_THREADS if the linking with libpthread
2403 did not happen. Affected file configure.in.pre.
2405 * Added notion to protocol specification that server must
2406 verify the sent authentication payload with CMODE when
2407 setting the channel founder key. Implemented it to the
2408 server. Affected file silcd/command.c.
2410 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Added _EXTRA_DIST SILC distribution variable to the
2413 distributions file. It is used to conditionally add extra
2414 files or directories to the specific distribution. Affected
2415 files ./prepare, Makefile.am.pre and distributions.
2417 Removed the `_' from the start of the distribution names.
2420 * Added README.WIN32 for instructions to compile the Toolkit
2423 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Fixed a double free in disconnection in the server. Affected
2426 file is silcd/server.c.
2428 * Fixed the lib/silcske/groups.c to work now also with GMP
2429 MP library. The string conversion did not work when using
2430 specific base and the base is indicated in the string as well.
2432 * Created win32/ directory which now includes MSVC++ specific
2433 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2434 It will appear only in the toolkit distribution
2436 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Changed the key material distribution function in case when
2439 the hash output is too short. The data is now concatenated
2440 a bit differently than it used to. Made the change to the
2441 SKE protocol specification.
2443 * Added better GMP detection to configure.in.pre. A patch
2446 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Fixed a minor bug in SKE that might cause some problem on
2449 some platforms. Affected file lib/silcske/silcske.c.
2451 * Added the cookie checking for initiator in the SKE. It checks
2452 that the responder returns the sent cookie unmodified. The
2453 affected file is lib/silcske/silcske.c. Added new SKE
2454 error type INVALID_COOKIE that can be sent during the
2455 negotiation. Fixed some memory leaks as well.
2457 * Added the "invalid cookie" error message to Irssi SILC client's
2460 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Added `task_max' field to the SilcClientParams to indicate
2463 the maximum tasks the scheduler can handle. If set to zero,
2464 default values are used. Affected file lib/silcclient/silcapi.h.
2466 * Fixed memory leaks in silc_client_close_connection. Affected
2467 file lib/silcclient/client.c.
2469 * Added silc_client_del_client_entry to client library to free
2470 all memory of given client entry. Affected file is
2471 lib/silcclient/idlist.[ch].
2473 * Added new functions silc_client_del_channel and
2474 silc_client_del_server to delete channel and server entries.
2475 Affected file lib/silcclient/[silcapi.h/idlist.c].
2477 * Removed silc_client_del_client_by_id from silcapi.h.
2479 * Fixed the INFO command to return the server's own info
2480 correctly when querying by Server ID. Affected file is
2483 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Removed the non-blocking settings in WIN32 code in the
2486 silc_sock_[read/write] and added SleepEx instead. Affected
2487 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2488 of input data is now checked with FIONREAD and ioctlsocket.
2490 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Call silc_schedule_task_del_by_context in the
2493 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2494 Affected file lib/silccore/silcprotocol.c.
2496 * Call silc_protocol_cancel for active protocols in the
2497 silc_server_close_connection if the funtion
2498 silc_server_free_sock_user_data has not been called.
2499 Affected file silcd/server.c.
2501 * Generic tasks cannot be deleted using the del_by_fd
2502 task deleting function since generic tasks does not match
2503 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2505 * Added a notion to SILCOPER help file that the SILCOPER works
2506 only on router server, not on normal server.
2508 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Added for WIN32 support for the new scheduler as well.
2511 Affected file lib/silcutil/win32/silcwin32schedule.c.
2513 * Fixed the SHA1 implementation to work on various platforms.
2515 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2518 API. It is part of the scheduler now. Everything else is
2519 as previously but some functions has changed their names.
2520 Checkout the lib/silcutil/silcschedule.h for the interface.
2521 Updated all applications to use the new interface. Affected
2522 files are lib/silcutil/silcschedule.[ch].
2524 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Found a bug in the SKE implementation. The HASH value,
2527 specified by the protocol, was not computed correctly. The
2528 public key of the responder was not added to the computation
2529 even though it is mandatory. Affected file lib/silcske/silcske.c.
2530 This unfortunately causes incompatibilities with older
2531 clients and servers.
2533 * Added WIN32 specific network init and uninit functions:
2534 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2535 the Winsock2. Affected file lib/silcutil/silcnet.h and
2536 lib/silcutil/win32/silcwin32net.c.
2538 * Set the socket always to nonblocking mode on WIN32 after
2539 reading data or writing data. Affected file is
2540 lib/silcutil/win32/silcwin32sockconn.c.
2542 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Fixed various compilation problems under WIN32. Affected
2545 files lib/silcutil/win32/silcwin32thread.c and
2546 lib/silcutil/win32/silcwin32schedule.c.
2548 * Removed all _internal.h #includes from public header
2549 files. Internal headers must never be included from
2552 Removed also the lib/silcske/payload_internal.h file.
2554 * All include files that may be needed (public and some others
2555 included by the public headers) by application developers are
2556 now copied to the ./includes directory. It does not copy any
2557 internal headers. Affected file Makefile.defines.pre and all
2558 Makefile.am's under lib/ and subdirs.
2560 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Do not change the ~/.silc directory's permissions automatically.
2563 Affected file irssi/src/silc/core/clientutil.c.
2565 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Do not cancel the protocol in silc_server_close_connection
2568 it might cause recursion. Now cancelled in the function
2569 silc_server_free_sock_user_data. Affected file silcd/server.c.
2571 * Fixed the silc_server_remove_clients_by_server to regenerate
2572 the channel keys correctly finally. Added also new function
2573 silc_server_remove_clients_channels to actually do it.
2574 Affected file silcd/server.c.
2576 * Fixed the silc_server_new_channel to not crash by giving
2577 wrong router to the new channel. Affected file is
2578 silcd/packet_receive.c.
2580 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2583 which is given as argument to the silc_client_alloc now.
2584 It can be used to configure the client and set various parameters
2585 that affect the function of the client.
2587 * The USERS command in server did not check whether the channel
2588 is private or secret. Affected file silcd/command.c.
2590 * Added new argument to the USERS command in protocol specification.
2591 The USERS command now can take the channel name as argument
2592 as well. Added support for this in client and server and
2593 updated the protocol specs.
2595 * Completed the GETKEY command in client. It can be now used
2596 to fetch also servers public key not only some clients.
2597 Affected files lib/silcclient/command[_reply].c.
2599 * Added silc_client_get_server to return server entry by the
2600 server name. Affected files lib/silcclient/silcapi.h and
2603 * Redefined the IDENTIFY command in protocol specification to be
2604 more generic. It now can be used to query information about
2605 any entity in the SILC Network, including clients, servers and
2606 channels. The query may be based either the entity's name
2607 or the ID. Added support for this in both client and server.
2609 Affected files silcd/command.c and lib/silcclient/command.c
2610 and command_reply.c.
2612 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2613 the _from_client and _from_server functions. Affected file
2616 * Added silc_client_get_channel_by_id_resolve to the file
2617 lib/silcclient/silcapi.h to resolve channel information by
2618 its ID. Added also silc_client_get_channel_by_id that
2619 does not resolve it from the server.
2621 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Added SilcServerEntry context into the client library
2624 to represent one server. The INFO command now allocates
2625 these to save the resolved server info. For now on the
2626 client library will also keep information about servers,
2627 connected and resolved with INFO.
2629 The INFO command now allocates the SilcServerEntry context
2630 and saves the server info there. The COMMAND_REPLY in
2631 the INFO now returns the parameters to application in
2632 same order as defined in the protocol specification.
2634 The entries are cached in the client->server_cache.
2636 * The INFO command is now issued after received the Client ID
2637 from the server. Affected file lib/silcclient/client.c.
2639 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2640 to the application as the mode changer might be server.
2641 It is guaranteed that NULL is not returned anymore to the
2642 application. Affected file lib/silcclient/client_notify.c.
2644 The ID Type is now also passed to the application so that
2645 it can check whether the returned entry is SilcClientEntry
2648 Added new function silc_client_get_server_by_id to return
2649 the server entry by ID. Affected files are the
2650 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2652 * Do not create the channel in the Irssi SILC Client when issuing
2653 the JOIN command but when received the sucessful JOIN command
2654 reply. Otherwise the channel might get created even though we
2655 could not join it. The Affected file is
2656 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2658 * Fixed a channel joining bug in router. The router must also
2659 check the channel modes, invite and ban lists etc. when serving
2660 the JOIN command sent by normal server. Affected file is
2661 silcd/command.c. The router now resolves the client's
2662 information from the server who sent the JOIN command if it
2663 does not know it, and processes the JOIN command only after
2666 * Changed the SilcCommandCb to take new argument; void *context2.
2667 Affected file lib/silccore/silccommand.h
2669 The second argument in the command callbacks in the server now
2670 includes the SilcServerCommandReplyContext if the command was
2671 called as pending command callback from the command reply.
2672 Otherwise it is NULL. When called as pending the status of the
2673 command reply will be checked and if it was erronous the
2674 error will be sent to the original sender of the command.
2675 This way the client always receives the error messages even
2676 though the server was actually the one who received the error
2677 when it resent the command to router, for example. Affected
2678 files silcd/command[_reply].[ch].
2680 * Fixed sending WHOWAS command's error message to client if
2681 the requested client could not be found. It was missing.
2684 * Changed the CMODE and CUMODE commands reply arguments in the
2685 protocol specification. The Channel ID is now sent in both
2686 of the commands to identify the channel. Implemented this
2687 new feature to the client and server. Affected files
2688 lib/silcclient/command_reply.c and silcd/command.c.
2690 * Made better checks for invite and ban lists in the JOIN
2691 command in server. Affected file silcd/command.c.
2693 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * The server now performs the incoming host IP/DNS lookup
2696 using the silc_socket_host_lookup and thus does not block
2697 the server anymore. Affected file silcd/server.c.
2699 * Completed the multi-thread support for SILC Scheduler in
2700 the lib/silcutil/silcschedule.c.
2702 * Fixed the configure.in.pre to detect the pthread correctly
2705 * Fixed a deadlock in silc_task_queue_wakeup in the file
2706 lib/silcutil/silctask.c.
2708 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Added new function silc_schedule_wakeup that is used in
2711 multi-threaded environment to wakeup the main thread's
2712 schduler. It needs to be used when a thread adds a new task
2713 or removes a task from task queues. After waking up, the
2714 scheduler will detect the task queue changes. If threads
2715 support is not compiled in this function has no effect.
2716 Implemented the wakeup mechanism to both Unix and WIN32
2717 systems. Affected files are lib/silcutil/silcschedule.[ch],
2718 lib/silcutil/unix/silcunixschedule.c and the
2719 lib/silcutil/win32/silcwin32schedule.c.
2721 * Added new function silc_task_queue_wakeup to wakeup the
2722 scheduler by the specified task queue. Affected file
2723 lib/silcutil/silctask.[ch].
2725 * The silc_socket_host_lookup_start now wakes up the scheduler
2726 after adding the timeout task. Affected file is
2727 lib/silcutil/silcsockconn.c.
2729 * The silc_socket_host_lookup is synchronous now if the threads
2730 support is not compiled in. However, the callback is still
2731 called asyncronously through the scheduler, anyway. Affected
2732 file lib/silcutil/silcsockconn.c.
2734 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Added new function silc_socket_host_lookup to perform
2737 asynchronous IP and FQDN lookups for the socket connection.
2738 Affected files lib/silcutil/silcsockconn.[ch].
2740 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2743 that may or may not compile the mutex support in.
2745 Changed the silc_mutex_alloc interface. It allocates the
2746 mutex now to the sent pointer and returns TRUE or FALSE.
2748 Affected file lib/silcutil/silcmutex.h.
2750 * Wrote the SILC Task Queue interface to support multi-threads.
2751 Affected file lib/silcutil/silctask.[ch].
2753 * Wrote the SILC Scheduler to support multi-threads. Affected
2754 file lib/silcutil/silcschedule.c.
2756 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2759 in lib/silcutil/win32/.
2761 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Defined SILC Mutex API and SILC Thread API and implemented
2764 them for Unix. Affected files are
2765 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2766 lib/silcutil/unix/silcunixmutex.c and
2767 lib/silcutil/unix/silcunixthread.c.
2769 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Fixed the silc_server_remove_clients_by_server's channel
2772 key re-generation. The hash table handling was incorrect
2773 and would not work with many channels. Affected file is
2776 * Fixed some memory leaks around the server code.
2778 * Rewrote the silc_server_get_users_on_channel to support IPv6
2779 based Client ID's. Affected file silcd/server.c.
2781 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2782 specification. However, a separate document must be written
2783 to define the detailed signing procedure and the payload
2784 associated with the flag. Defined the flag to the
2785 lib/silccore/silcchannel.h as well.
2787 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Changed the dynamic tables to static size tables in the
2790 lib/silccrypt/silchmac.c.
2792 * Removed GCC dependencies from the code. A patch by cras.
2794 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2796 * Do not show the error "Error receiving packet bla bla"
2797 in server if it really was not an error (-2 means that reading
2798 is pending). Affected file silcd/server.c.
2800 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Fixed a possible crash in silc_server_remove_clients_by_server
2803 in silcd/server.c. Fixed there also some memory leaks.
2805 * Fixed the silc_idlist_replace_client_id. It could replace
2806 wrong key in the hash table. Affected file silcd/idlist.c.
2808 * Do not check whether there are global users on the channel
2809 if the channel->global_users is FALSE. Affected functions
2810 silc_server_remove_from_one_channel and
2811 silc_server_remove_from_channels in silcd/server.c. Also,
2812 do not check if the removed client is local as we can be
2813 sure that global client was not removed from the channel
2814 and checking for global users is not needed.
2816 * The silc_server_remove_clients_by_server now re-generates
2817 the channel keys correctly for those channels that had
2818 clients removed from them. Affected file silcd/server.c.
2820 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Found the reason of random crashes in the server. We weren't
2823 ignoring the SIGPIPE signal (which can be sent in write())
2824 and it crashed the server. Affected file silcd/silcd.c.
2826 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Assure that sock->user_data is not NULL in the function
2829 silc_server_packet_send in silcd/packet_send.c.
2831 * Disconnect the remote connection if it could not be added
2832 to any ID lists in the server. The affected file is
2835 * Check in silc_server_packet_send[_real/dest] that the
2836 socket is not disconnecting and ignore the data if it is.
2837 Affected file silcd/packet_send.c.
2839 * Define inline to __inline on native WIN32 compilation.
2840 Affected file includes/silcwin32.h.
2842 * Added some explicit type casts for inline code since MSVC
2843 require them. Affected files lib/silcutil/silcbuffer.h,
2844 lib/trq/silcdlist.h and lib/trq/silclist.h.
2846 * Print warning in log files from now on if the packet
2847 decryption fails. Affected file silcd/server.c.
2849 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Changed the `say' client operation's interface to accept
2852 new `type' argument to indicate the type of the message sent
2853 by the library. The application may filter the library's
2854 messages according the type. The affected file is the
2855 lib/silcclient/silcapi.h.
2857 * Added two new functions to lib/silcclient/silcapi.h:
2858 silc_client_del_client and silc_client_del_client_by_id.
2859 Affected file lib/silcclient/idlist.c.
2861 * Moved the clientincludes.h from includes/ to silc/ and
2862 serverincludes.h from includes/ to silcd/.
2864 * The modes for the CMODE and CUMODE are now passed as
2865 uint32 for application with COMMAND_REPLY. The affected
2866 file is lib/silcclient/command_reply.c.
2868 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * /WHOIS without arguments shows client's own information.
2871 Affected file lib/silcclient/command.c.
2873 * Changed PING to not accept any arguments. The specs
2874 says that client can ping only the connected server so
2875 requiring an argument is not needed. Affected file is
2876 lib/silcclient/command.c.
2878 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Fixed a fatal bug in private message sending and reception
2881 encryption and decryption when using private message keys.
2882 The implementation was incorrect and did not follow the
2883 specification. It causd that some of the message were
2884 lost since it did not use the sending and receiving keys
2885 as the protocol suggests. This has been fixed and will cause
2886 incompatibilities with older clients when sending private
2887 message encrypted with private message keys. Affected files
2888 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2889 and various other in Irssi SILC Client.
2891 Added `responder' boolean argument to the functions
2892 silc_client_add_private_message_key[_ske] to indicate when
2893 the key is added as responder or initiator of the key
2896 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Removed the silc_ske_check_version function and created
2899 a SilcSKECheckVersion callback. Added also a function
2900 silc_ske_set_callbacks that is now used to set all SKE
2901 callbacks. The callback functions are not given to
2902 the SKE functions anymore, but this function is used to
2905 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2907 * Added `silc_version' argument to the silc_client_alloc
2908 to define the version of the application for the library.
2909 The library will use the version string to compare it
2910 against the remote host's (usually a server) version
2911 string. Affected file lib/silcclient/silcapi.h
2913 * Added the KE protocol context to Key Agreement context
2914 in client library so that we can abort the SKE if it
2915 is in process when we get timeout. Affected file is
2916 lib/silcclient/client_keyagr.c.
2918 * Do not resolve the client ID forever if it returns in the
2919 first time that such client does not exist. This was done
2920 for example with private message. Affected file is
2921 lib/silcclient/client_prvmsg.c.
2923 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Do not add regex.h for WIN32. The affected file
2926 includes/silcincludes.h.
2928 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2929 not work yet 100%. It generates the DLL's automatically
2930 when compiling with --with-win32 under cygwin.
2932 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * lib/contrib/regex.c is not compiled on WIN32.
2936 * Added silc_net_get_socket_opt function to the
2937 lib/silcutil/silcnet.h.
2939 * Added includes/silcwin32.h for WIN32 specific includes
2942 * Do not use ptime structure or any of the posix process
2943 functions on WIN32 in lib/silccrypt/silrng.c.
2945 * Added silc_gettimeofday to provide generic function
2946 for struct timeval on all platforms. Added the function
2947 to lib/silcutil/silcutil.h.
2949 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2952 library as they clearly belong there. As a plus side we
2953 can make the actual socket connection routines platform
2956 Added also new generic function silc_socket_read and
2957 silc_socket_write (that used to be silc_packet_[read/write].
2958 The implementation of these are platform specific.
2960 * Added WIN32 specific routines of silc_socket_[read/write]
2961 to lib/silcutil/win32/silcwin32sockconn.c.
2963 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Added preliminary support for native WIN32 compilation under
2966 cygwin (using the -mno-cygwin option for GCC) to the
2967 ./configure.in.pre. The --with-win32 now prepares the
2968 compilation for native WIN32.
2970 * Rewrote the SILC Scheduler interface in the file
2971 lib/silcutil/silcschedule.h. The scheduler is now context
2972 based and does not have anymore any global static scheduler.
2973 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2974 and created lib/silcutil/win32 directory for WIN32 based
2977 * Added Unix specific network routines to the
2978 lib/silcutil/unix/silcunixnet.c and the old
2979 lib/silcutil/silcnet.c includes now only generic routines.
2981 Added WIN32 specific network routines to the
2982 lib/silcutil/win32/silcwin32net.c.
2984 * Added Unix specific utility functions from the
2985 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2987 * Added WIN32 SILC Scheduler to the file
2988 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2991 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Do not handle JOIN notify in the server if the target client
2994 is not registered (idata->registered == FALSE). The affected
2995 file is silcd/packet_receive.c.
2997 * Update the nickrec->founder in event_cumode in the Irssi SILC
2998 client. Affected file irssi/src/silc/core/silc-channels.c.
3000 * Fixed the CUMODE_CHANGE notify handling in the server when
3001 server and router are announcing their clients on channels.
3002 Now the mode changes are saved and notified correctly. The
3003 affected file is /silcd/packet_receive.c.
3005 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3006 They really did not replace the cache entry in the ID Cache.
3007 Now they do that. Affected file silcd/idlist.c.
3009 * Fixed the KICK notify handling in the Irssi SILC client to
3010 update the channel records so that the kicked client does not
3011 appear to be on the channel. The affected file is
3012 irssi/src/silc/core/silc-channels.c.
3014 * Always update the conn->current_channel when executing command
3015 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3017 * Fixed the KILL notify handling in Irssi SILC client to remove
3018 the killed client on all channels.
3020 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Fixed the silc_parse_command_line to remove extra spaces
3023 from the start and end of the arguments. Affected file is
3024 lib/silcutil/silcutil.c.
3026 * Cancel and free any active protocol in the function
3027 silc_server_close_connection. Affected file silcd/server.c.
3029 * Cancel and free any active protocol in the function
3030 silc_client_close_connction. Affected file is
3031 lib/silcclient/client.c.
3033 * Do not execute the KILL command for clients that are in
3034 history (ie. they are not in the network). Affected file is
3037 * Fixed KILL notify handling, client does not crash anymore.
3038 Affected file irssi/src/silc/core/silc-channels.c.
3040 * Reduced the default packet buffer size from 2048 to 1024 in
3041 lib/silccore/silcpacket.c.
3043 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3044 counter to the SKE context that is incresed when the SKE library
3045 performs async operation outside the library. If the outside
3046 process frees the SKE context and FREED status will be set
3047 and the library will detect after the sync operation that the
3048 libary is freed. The affected files are
3049 lib/silcske/silcske[_status].[ch].
3051 * Resolve the client entry information in the function
3052 silc_client_channel_message to assure that NULL pointer is not
3053 passed as client entry to the application. */
3055 * Fixed the task timeout calculation to assure that there is
3056 never negative timeouts. The affected file is
3057 lib/silcutil/silcschedule.c.
3059 * Fixed the channel user mode notification sending in server.
3060 It was sent point-to-point to the router (or to server by router)
3061 but it needs to be destined to a channel. The routines now
3062 supports sending the channel user mode notifys to the channels
3063 when announcing clients and channels. Affected files are
3064 silcd/server.c and silcd/packet_receive.c.
3066 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3067 It did not actually replace the old channel entry in the cache.
3068 Affected file lib/silcclient/client_notify.c.
3070 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Fixed a possible crash in silc_packet_send_prepare. It now
3073 assures always that there is enough space in the buffer and
3074 at the tail area of the buffer (for MAC).
3076 Fixed the inbound buffer reallocation in silc_packet_read.
3077 It was old code and did not handle the reallocation correctly.
3080 The affected file is lib/silccore/silcpacket.c.
3082 * Fixed buffer overflow in silc_parse_nickname in the file
3083 lib/silcutil/silcutil.c.
3085 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * make install generates new server keys only if there is not
3090 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3093 Added check that if the NOREPLY is set then we will not send
3094 the away message. This avoids infinite loop of away messages
3095 if both clients are away. The affected file is
3096 lib/silcclient/client_prvmsg.c.
3098 * Fixed client crash if /NICK was given without arguments.
3099 Affected file lib/silcclient/command.c.
3101 * Server does not send the invite list in INVITE command back
3102 to the client if the list was not altered. Added this notion
3103 to the protocol spec as well. Affected file silcd/command.c.
3105 Fixed possible crash in INVITE command by checking the
3106 value of silc_server_get_client_route command.
3108 * Fixed the INVITE notify type handling. The arguments are now
3109 taken in correct order and client does not crash. The affected
3110 file is irssi/src/silc/core/silc-channels.c.
3112 Removed the "Inviting xxx to channel" message from the
3113 client library away and let the application handle it.
3114 Affected file lib/silcclient/command.c. Added that message
3115 to Irssi SILC client's message formats.
3117 * Fixed CMODE command crash in client. It now checks the
3118 amount of arguments correctly and does not crash. The affected
3119 file is lib/silcclient/command.c.
3121 * Do not create new channel automatically in silc_channels_join
3122 but check whether the channel by that name already exists.
3123 Affected file irssi/silc/core/silc-channels.c.
3125 * Do not send the SERVER_SIGNOFF to router if the disconnected
3126 entity was the router. Affected file silcd/server.c.
3128 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3129 SILC client as it was missing from there.
3131 Added the handling of the KICK notify to the Irssi SILC client
3132 as it was missing. Added "you have been kicked" message to
3133 Irssi SILC client's message modules formats.
3135 Added the handing of the KILL notify to the Irssi SILC client
3136 as it was missing. Added the kill message module formats
3139 The affected file is irssi/src/silc/core/silc-channels.c.
3141 * The router did not save the channel mode the server announced.
3142 Affected file silcd/packet_receive.c.
3144 * Fixed a possible crash in INFO command in server. If the
3145 server did not provide the server info it crashed. Affected
3146 file silcd/command.c.
3148 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Fixed the GETKEY command in the server to check also the
3151 global list. Otherwise the GETKEY would not work correctly
3152 in normal SILC server. Affected file silcd/command.c.
3154 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Fixed GETKEY crash, it crashed if the command did not succseed.
3158 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3160 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3161 is now real and not just an macro interface to GMP.
3163 Removed the entire GMP from the source tree and imported new
3164 NSS MPI library instead. Reason for removing GMP is that it is
3165 extremely large and compiles extremely slow. The NSS MPI
3166 is only a few files and compiles in less than 10 seconds.
3167 The speed is also about the same as GMP. The MPI is imported
3168 to lib/silcmath/mpi.
3170 If the system has GMP installed we will still use the GMP.
3171 If it is not then the NSS MPI will be compiled.
3173 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Merged a long nickname (127 characters long) crash bugfix from
3176 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3178 * Merged a freed memory reference bugfix from Irssi CVS tree.
3179 Affected file irssi/src/core/commands.c.
3181 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Added the server's public key sving and verification to the
3184 server when performing the SKE. This was missing and the
3185 remote server's (or router's) public key was accepted without
3186 checking whether we have it previously or trust it at all.
3187 Affected file silcd/protocol.c.
3189 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Check in the silc_server_timeout_remote if protocol is active
3192 and make sure that the protocol's final callback is called so
3193 that all memory if freed. Affected file silcd/server.c.
3195 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * silc_server_whois_send_reply crashed the server if the nickname
3198 was 127 characters long. Affected file silcd/command.c.
3200 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Added sanity check to the silc_server_new_client. If the hostname
3203 is provided inside username then check that the provided hostname
3204 really is the same as the resolved one. If the hostname was not
3205 resolved then check it from the public key. Affected file is
3206 silcd/packet_receive.c.
3208 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3209 if the server disconnected us and the connection is not valid
3210 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3212 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3213 the library to the lib/silcutil/silcutil.[ch].
3215 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Close log file after open. Affected file
3218 lib/silcutil/silclog.c.
3220 * Check whether sock == NULL in silc_client_send_packet and return
3221 if it is. Affected file lib/silcclient/silcclient.c.
3223 * Check rec->entry == NULL in the Irssi SILC Client before
3224 sending the channel message. Affecte file is
3225 irssi/src/silc/core/silc-servers.c.
3227 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Merged a splitted window bugfix from Irssi CVS tree. The
3230 affected file is irssi/src/fe-text/textbuffer-view.c.
3232 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3233 It did not print nickname.
3235 * Improved the distributions system a bit.
3237 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3240 irssi/src/fe-text/gui-window.c.
3242 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3243 to in-active server. The affected file is
3244 irssi/src/silc/core/client_ops.c.
3246 * Resolve the client in USERS command reply if the entry does
3247 not have username resolved. The affected file is
3248 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3249 command to WHOIS command to really resolve stuff. The USERS
3250 is not used any more in any critical section so WHOIS can
3251 be used even though it might be slower than IDENTIFY.
3253 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3256 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Changed the protocol API a bit more consistent in the
3259 lib/silccore/silcprotocol.[ch].
3261 * Changed the following headers to ROBODoc format:
3263 lib/silccore/silcpayload.h
3264 lib/silccore/silcprotocol.h
3265 lib/silccore/silcsockconn.h
3267 All core library headers are now formatted.
3269 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Fixed a bug in Irssi SILC client; do not show that you are
3272 server/router operator if you really are not. Affected file is
3273 irssi/src/silc/core/client_ops.c.
3275 * Renamed silc_command_free_payload to silc_command_payload_free.
3276 Affected file lib/silccore/silccommand.h
3278 * Added silcmath.h to include the prototoypes of various routines
3279 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3282 * Changed the following headers to ROBODoc format:
3284 lib/silccore/silcchannel.h
3285 lib/silccore/silccommand.h
3286 lib/silccore/silcid.h
3287 lib/silccore/silcidcache.h
3288 lib/silccore/silcmode.h
3289 lib/silccore/silcnotify.h
3290 lib/silccore/silcpacket.h
3291 lib/silcmath/silcmath.h
3293 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Added checking to the server code not to start the server if
3296 ciphers and stuff are not configured properly. Affected files
3297 silcd/serverconfig.[h] and silcd/server.c.
3299 * Changed the layout of the header files of the public interfaces
3300 in the SILC libraries. The new layout supports ROBODoc
3301 documentation tool (and some others) so that it is easy to create
3302 a library reference manual. All the other headers and source
3303 code must still follow the CodingStyle document. Also source
3304 code must not include these ROBODoc stuffs, only the headers.
3305 Furthermore, all public interface headers must now be named
3306 by using `silc' prefix, example: silcapi.h, silccipher.h.
3307 Some files were renamed due to this. All the other headers
3308 must not be used as public interfaces. I will update the
3309 CodingStyle document later. Changed following headers, so far:
3311 lib/silcclient/silcapi.h
3312 lib/silccore/silcauth.h
3313 lib/silccore/silcprivate.h
3314 lib/silccrypt/silcdh.h
3316 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Removed silc_client_packet_send_flush from the client library
3321 as it is not needed. Affected file lib/silcclient/client.[ch].
3323 * Added printing of message of unresolved authentication method
3324 to the Irssi SILC client. Added it to the module formats.
3325 Removed the same message from the client library.
3327 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added new distribution feature, DISTLABEL. Every distribution
3330 can define own preprocessor label that can be used in the
3331 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3332 file distributions, acconfig.h.pre and prepare.
3334 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added Makefile.defines_int to include the actual definitions
3337 for Makefile.defines.in. Tested the new distribution system,
3338 created distributions and tested installation.
3340 * Added AWAY message printing to the Irssi SILC client. Added
3341 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3343 * Added SCONNECT command to call the SILC's CONNECT command.
3344 Cannot use CONNECT directly since Irssi uses that internally.
3345 Affected file irssi/src/silc/core/silc-servers.c.
3347 Added ACTION local command. It is same as ME command but takes
3348 the channel as mandatory argument.
3350 Rewrote some of the Irssi's help files to suite for SILC
3353 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Added Makefile.defines[.in] that should for now on be included
3356 in all Makefile.am file in the source tree. That file includes
3357 all common compilation definitions for SILC source tree.
3359 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Minor changes to the ./prepare script to change the package
3362 name according the distribution name to the configure.in.
3364 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Created new distribution system. Added file `distributions'
3367 that defines all the distributions that can be created out of
3368 the SILC source tree. The ./prepare script now reads that
3369 file to determine how to prepare the distributions. The
3370 first argument to the ./prepare is the name of the distribution
3371 and second is the version of the distribution. If given
3372 without arguments it creates the default (toolkit) distribution
3373 with the default version (defined in ./prepare).
3375 All Makefile.am files that are subject to the distributions
3376 are now named as Makefile.am.pre. These are ./Makefile.am
3377 and lib/Makefile.am. Others may be changed later.
3379 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Added invite list, ban list, some key management and connection
3382 error message printing to module formats in the Irssi SILC client.
3384 * Added new silc_client_set_away_message to set the away message
3385 that is back to the person who sent private message. The
3386 affected file lib/silcclient/silcapi.h and the
3387 lib/silcclient/client_prvmsg.c.
3389 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Fixed the private message sending in the Irssi SILC client,
3392 added local command KEY to the Irssi SILC client.
3394 Added key management and key agreement message formats to the
3395 irssi/src/fe-common/silc/module-formats.[ch].
3397 Added USERS (alias WHO) printing, server/router operator
3398 indication and LIST command printing to the module formats.
3400 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Fixed channel joining notify handling, cumode notify handling
3403 from Irssi SILC client.
3405 * Added SILC specific module-formats to the Irssi SILC client so
3406 that SILC specific message hilighting, colors etc is possible.
3407 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3409 Added channel mode, channel user mode, actions, notices,
3410 whois and whowas printing to the the module-formats.c.
3412 * Fixed a bug in channel deletion in the server. The channel
3413 is not left to the cache even if the channel founder auth mode
3414 is set when there are no users anymore on the channel. Affected
3415 file silcd/server.c.
3417 * The silc_net_localhost now resolves the entire hostname including
3418 the domain name. Affected file lib/silcutil/silcnet.c.
3420 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Changed the ask_passphrase client operation to be ascynchronous.
3423 It has now a completion callback and a context that the
3424 application must call after it has got the passphrase from
3425 the user. Affected files lib/silcclient/silcapi.h,
3426 lib/silcclient/protocol.c, lib/silcclient/command.c and
3429 Added SilcAskPassphrase callback that the application calls
3430 to deliver the passphrase to the library.
3432 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3433 The public key verification and especially a certificate
3434 verification is asynchronous procedure.
3436 Added new SILC_SKE_STATUS_PENDING status to indicate the
3437 request is pending and a callback will be called to finalize
3440 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3441 indicate that remote end did not send its public key (or
3442 certificate), even though we require it. Added check for this
3443 condition in the SKE. This was a security bug, now fixed.
3445 Defined new SilcSKEVerifyCbCompletion callback that is called
3446 when the verification process is completed.
3448 The affected files lib/silcske/silcske_status.h and
3449 lib/silcske/silcske.[ch].
3451 * Changed the verify_public_key client operation to be async
3452 as well. Defined SilcVerifyPublicKey callback that is used to
3453 indicate the success of the public key verification process.
3455 Changed the server and client to use the new async client
3458 * Changed the Irssi SILC client's internal scheduler to be called
3459 twice as many times as it used to be. As a result the client
3460 should be a bit faster now. Affected file is
3461 irssi/src/silc/core/silc-core.c.
3463 * Added support to Irssi SILC client of asynchronous public key
3464 verification and passphrase inquiry. Affected file is
3465 irssi/src/silc/core/silc-core.c.
3467 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Do not say "You have left channel %s" in client library.
3470 Moved it to the application. Affected files are
3471 lib/silcclient/command.c and silc/client_ops.c.
3473 * Fixed silc_client_get_clients. Command context was not
3474 duplicated and was freed memory in the callback. Affected
3475 file lib/silcclient/idlist.c.
3477 * Do not say "you are now talking..." on JOIN command in the
3478 client library. The appliation must handle it.
3480 * Do not say ".. changed topic to" in command reply in the
3481 client libary. The application must handle it.
3483 * Fixed TOPIC command sending in the client library.
3485 * Fixed a memory leak in silc_client_command_free in the file
3486 lib/silcclient/command.c.
3488 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Imported a modified version of Irssi client to the source tree.
3491 The Irssi will be used to create a new client called
3492 Irssi SILC. Imported to irssi/.
3494 Added silc_core_init_finish function to the Irssi. Affected
3495 file irssi/configure.in.
3497 A lot changes in the Makefile.ams around the irssi tree.
3499 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Do not rehash if the new size is same as the old size of the
3502 hash table, in the silc_hash_table_rehash*. The affected file
3503 lib/silcutil/silchashtable.c.
3505 * Replaced hash_table_del_by_context calls from the server
3506 (when channel->user_list and client->channels) to the
3507 hash_table_del as it is sufficient and faster.
3509 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Added silc_hash_table_list, silc_hash_table_get and the
3512 SilcHashTableList structure to provide an alternative way to
3513 traverse the hash table. The affected files are
3514 lib/silcutil/silchashtable.[ch].
3516 * Changed the server's idlist routines to use the hash table
3517 routines to optimize the code.
3519 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Replaced the client entry's `channel' list and channel entry's
3522 `user_list' list to hash tables for optimized lookup. Changed
3523 the code to use the hash table interface around the code.
3524 Affected file lib/silcd/idlist.[ch].
3526 * Added `auto_rehash' boolean argument to the function
3527 silc_hash_table_alloc to indicate whether the hash table should
3528 auto-rehash when it thinks is appropriate time. It will
3529 increase the hash table size if the there is twice as much
3530 entries in the table than the size of the table, and will
3531 decrease the size if there are twice as less entries than
3532 the size of the table.
3534 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3538 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * silc_idcache_purge_by_context deletes the entry now by context
3541 as it is supposed to do. Affected file lib/silccore/idcache.c.
3543 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3544 client is not anymore valid (WHOWAS givens the info) and not
3545 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3547 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Removed the `data' and `data_len' arguments from the ID Cache
3550 interfaces and added `name' argument. ID Cache does not handle
3551 anymore the binary data only a names associated with given ID.
3553 * When hashing a Client ID with silc_hash_id the entire ID is
3554 not hashed anymore, instead only the hash of the Client ID is
3555 hashed. This way we can access the Client ID from the cache
3556 with Client ID but with the hash of the ID (which is a hash of
3557 the nickname) as well without any difference in performance.
3559 Added also silc_idcache_find_by_id_one_ext to do one on one
3560 searching when we have the actual ID. Added also function
3561 silc_hash_client_id_compare. The affected files are
3562 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3564 * When hashing the name associated with a ID it is always done
3565 in lowercase. This way we can access the cache without worrying
3566 about case-sensitivity, even though, for example nicknames are
3569 * Fixed a bug in server with channel message sending. It put
3570 wrong ID type as destination ID. The affected file
3571 silcd/packet_send.c.
3573 * silc_idcache_del_by_context now deletes from all hash tables
3574 by context. Affected file lib/silccore/idcache.c.
3576 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Changed the client library to use the new ID Cache interface.
3579 Changes around the source tree.
3581 * Added silc_hash_table_rehash_ext to rehash with specific
3582 hash function. Affected file lib/silcutil/silchashtable.[ch].
3584 * Added silc_hash_string_compare to compare two strings in the
3585 hash table. Affected file lib/silcutil/silcutil.[ch].
3587 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Added new function silc_idcache_del_by_context into the
3590 lib/silccore/idcache.[ch].
3592 * Changed the server's ID list routines to use the new ID Cache
3593 interface. Changes around the source tree.
3595 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Added silc_hash_table_del[_by_context]_ext functions in to the
3598 lib/silcutil/silchashtable.[ch].
3600 Removed silc_hash_table_find_all* routines and added new
3601 silc_hash_table_find_foreach to replace them.
3603 Added silc_hash_table_replace_ext function as extended
3604 replacing function. Separated the simple hash table interface
3605 from the extended hash table interface in the file
3606 lib/silcutil/silchashtable.h.
3608 * Fixed minor bugs and changed it to use some of the new
3609 hash table functions in lib/silccore/idcache.c
3611 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Added new function silc_hash_table_find_all to return all keys
3614 in the hash table by the specified key. As the hash table is
3615 collision resistant it also makes it possible to have several
3616 duplicate keys in the hash table. This function may be used to
3617 find all of the keys from the hash.
3619 Added user_context arguments to the SilcHashFunction,
3620 SilcHashCompare and SilcHashDestructor to deliver user specified
3623 Added new fuctions silc_hash_table_find[_all]_ext to do
3624 extended lookup with specified hash and compare functions and
3625 specified user contexts.
3627 Added new function silc_hash_table_add_ext to add the key
3628 with specified hash function and user context.
3630 Added new function silc_hash_table_foreach to traverse all
3631 entrys in the hash table. Added SilcHashForeach callback
3634 Added new function silc_hash_table_del_by_context to delete
3635 the entry only if the context associated with the key matches.
3637 Affected files are lib/silcutil/silchashtable.[ch].
3639 * Removed silc_hash_[server/client/channel]_id and added just
3640 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3641 silc_hash_id_compare to compare two ID's using as the hash table
3642 comparison function. Added also silc_hash_data to hash
3643 binary data and silc_hash_data_compare to compare it.
3645 * Removed silc_idlist_find_client_by_hash as it is not needed
3646 anymore. Affected file silcd/idlist.[ch].
3648 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3649 to use internally the SilcHashTable. The new ID Cache is a lot
3650 faster than the old one. Some of the ID Cache interface was also
3651 rewritten and obsolete and stupid functions were removed.
3653 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Added entry_count field to the SilcHashTable to keep the number
3656 of the entries in the table. Implemented the function
3657 silc_hash_table_rehash. Added new function
3658 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3660 Fixed a minor bug in silc_hash_table_free.
3662 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3663 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3664 into the lib/silcutil/silcutil.[ch].
3666 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Implemented a collision resistant hash table into the
3669 lib/silcutil/silchashtable[ch]. See the header and the source
3670 for the SilcHashTable API.
3672 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Merged dotconf version 1.0.2 into lib/dotconf.
3676 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Do not compile anything in lib/silcsim/* if the SIM support
3679 is not enabled. The tree should now compile without problems
3682 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Compiled the SILC under cygwin. Compiled and tested briefly
3685 without problems. More tests needed. The SIMs didn't compile
3688 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3690 * Fixed possible crash in silc_get_username in the
3691 lib/silcutil/silcutil.c.
3693 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Fixed a va_arg in silc/client_ops.c.
3697 * Oops, RC5 routines were named AES and caused some problems
3698 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3700 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Added new SilcIDIP structure into the lib/silccore/id.h and
3703 replaced the old `ip' fields from all SILC ID's to that type.
3704 This is a step towards IPv6 support.
3706 The silc_id_get_len takes now the ID as an extra argument.
3707 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3708 both IPv4 and IPv6 based ID's.
3710 The affected files are lib/silccore/id.[ch] and other files
3711 around the tree using these routines.
3713 * Removed the ID length arguments in server from various
3714 silc_server_send_notify_* routines -> they are not needed
3717 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Fixed memory leak in silc_encode_pem_file in the file
3720 lib/silcutil/silcutil.c.
3722 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Check minor version as well in the SKE. Affected files are
3725 silcd/protocol.c and lib/silcclient/protocol.c.
3727 * Added --identifier option to the server so that an identifier
3728 can be when creating the public key for the server. Affected
3729 file is silcd/silcd.c.
3731 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3732 lib/silccrypt/silcpkcs.c.
3734 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Register default ciphers and stuff when using -C option with
3737 the server. Affected file sildc/silcd.c.
3739 * Put back the servers public key filename format, it is better
3740 than the new one. For now, the client keys are saved with the
3741 new filename format. The affected file silc/client_ops.c.
3743 * Implemented the Cipher API for the rest of the ciphers that
3744 did not implement it or implemented it the wrong way.
3746 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Register default ciphers and stuff when using the -S option
3749 in the client. Affected file silc/silc.c. Same also when
3750 creating new key pair with -C option.
3752 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Fixed the silc_verify_public_key client operation function to
3755 save the public keys differently. The fingerprint is now
3756 used as filename and not the hostname. This way also the
3757 client keys are saved uniquely and not with hostnames. The
3758 affected file is silc/client_ops.c.
3760 * Trimmed the silc_hash_fingerprint function to remove extra
3761 whitespaces from the end of the fingerprint. The affected
3762 file is lib/silccrypt/silchash.c.
3766 * Added silc_cipher_register_default function to register all
3767 default ciphers. It can be used when configuration files
3768 does not exist and the application does not want any specific
3769 ciphers in any specific order.
3771 The SilcDList is now used as silc_cipher_list dynamically
3772 allocated cipher list. Removed the static list all together
3773 and now all ciphers must be allocated to the dynamic list.
3774 The silc_cipher_alloc routine was changed to check only the
3777 All silc_cipher_* routines that used to return int returns
3780 The affected files lib/silccrypt/silccrypt.[ch].
3782 * The same thing was done to silc_hash_* as for silc_cipher_*
3783 routines. Affected files lib/silccrypt/silchash.[ch].
3785 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3786 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3787 Added also silc_pkcs_[un]register[_default] functions.
3788 Removed the data_context from the PKCS API.
3790 * Added silc_hmac_register_default function to register default
3791 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3792 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3793 to unregister all hmacs at once.
3795 * Register the default ciphers, hash functions, PKCSs and HMACs
3796 if client's configuration file does not exist. The affected
3799 * The client did not load the hash functions from the SIM
3800 modules at all. Added support for this. Affected file is
3801 silc/clientconfig.c.
3803 * When decoding public key with silc_pkcs_public_key_decode, check
3804 the supported algorithm only if PKCS are registered. Affected
3805 file lib/silccrypt/silcpkcs.c. The same was done with the
3806 silc_pkcs_private_key_decode.
3808 * Fixed the SILC List routines to keep the list always in order.
3809 It used to change the list's order when traversing the list but
3810 not it preserves the order. Affected file lib/trq/silclist.h.
3812 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Added the client library to use the SilcSocketConnection's
3815 reference counter (by silc_socket_dup) to prevent the bug that
3816 the socket object may be freed underneath async operation.
3818 * The name resolv library checking fixes in the configure.in.pre.
3821 * Created new version of the protocol drafts for future
3822 development. The -03 drafts are the ones that will be changed
3823 in the trunk now and the -02 will remain as they are.
3825 * Send list of CUMODE notifys to the router when announcing
3826 the channel users to the router. Affected file silcd/server.c.
3827 If the router receiving channel founder CUMODE for a channel
3828 that already has channel founder it will send CUMODE notify
3829 to the sender to remove the channel founder rights from the
3830 announced client. Affected file silcd/packet_receive.c.
3832 * The CUMODE notify may now use Server ID as well as the entity
3833 who changes the mode. Updated protocool specs.
3835 * Updated INSTALL and README files.
3837 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * New web pages in the http://silc.pspt.fi. The pages was
3844 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Implemented the [DenyConnectin] config section in the server.
3847 Added silc_server_config_denied_conn to check whether incoming
3848 connection is denied. Affected file silcd/serverconfig.[ch].
3850 * Do not check the ports when checking the incoming configuration
3851 data if the port is 0, meaning any. Affected file is
3852 silcd/serverconfig.c.
3854 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Fixed buffer overflow in silc_string_compare in the file
3857 lib/silcutil/silcutil.c.
3859 * Fixed double free in silc_server_command_leave in the file
3862 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Fixed the version checking in the server. Affected file is
3867 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Fixed the configuration data fetching when accepting new
3870 connections in the server. Affected file silcd/server.c.
3872 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added `sender_entry' argument to the function
3875 silc_server_packet_relay_to_channel so that we can check
3876 whether some destination actually belongs to the same route
3877 the sender belongs (ie, we must not resend the packet to the
3878 sender). Affected file silcd/packet_send.[ch].
3880 * Added `servername' field to the SilcClientEntry in the server
3881 to hold the name of the server where client is from. Affected
3882 file is silcd/idlist.h.
3884 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Moved the channel message encrypting in the router betwen
3887 router connections from silc_server_channel_message to the
3888 silc_server_packet_relay_to_channel since we want to check
3889 whether we have anybody channel before encrypting anything.
3890 Affected files silcd/packet_[receive/send].c.
3892 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Fixed the [AdminConnection] server config section to support
3895 multiple entries. Affected file silcd/serverconfig.c.
3897 * Added support into the server to check the validity of the
3898 incoming connection before executing any KE or authentication
3901 * The connection configuration is now saved to the KE and
3902 connection auth protocol contexts and not fetched anymore in
3903 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3905 * The local hosts listenning address and port is also resolved
3906 now when starting the server. We want to have the socket object
3907 to include the real address and port for the listener. Added
3908 new function silc_net_check_local_by_sock into the files
3909 lib/silcutil/silcnet.[ch].
3911 * Fixed a broadcast bug in server -> do not broadcast if we
3914 * Fixed a routing bug. Do not route broadcast packets ever.
3915 Broadcast packets must be processed always and not routed since
3916 they may be destined to some other host than yourself and thus
3917 would get routed without no good reason. Affected file is
3920 * Added function silc_server_config_is_primary_route to check
3921 whether primary router connection has been configured (a router
3922 configuration that we are initiating). If there is not, we
3923 will assume that there is only two routers in the SILC network
3924 and we will use the incoming router connection as our primary
3925 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3927 * Changed the order of the broadcasting. Broadcast _after_ the
3928 packet has been processed not before. Affected file is
3931 * Fixed a [ClientConnection] parsing bug. The port was never
3932 parsed correctly thus resulting to port 0. Affected file
3933 silcd/serverconfig.c.
3935 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3936 argument and did not set the broadcast packet flag. Affected
3937 file silcd/packet_send.c. Fixed same bug in the function
3938 silc_server_send_notify as well.
3940 * If we receive NEW_ID packet for our own ID in the server, ignore
3943 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Removed the nickname from the Private Message Payload.
3948 Updated the code and the protocol specs.
3950 * Updated protocol specs for submitting to the IETF.
3952 * Tweaked the Random Number Generator a bit. Affected file
3953 lib/silccrypt/silcrng.c. Exported a new function
3954 silc_rng_[global]_add_noise which can be used to add more
3957 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Do not parse packets with different timeout when protocol
3960 is active -> may cause problem with rekey. Affected file
3963 * When server receives signoff notify it must not create
3964 new channel key if the client is on any channels since the
3965 sender of the signoff notify will create it.
3967 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Added printing of error messages during SKE protocol from the
3970 failure packet sent by server during SKE. Affected file
3973 * Removed the client's failure_callback handling with timeout
3974 and handle it immediately when received.
3976 * The SKE library returned wrong type in SUCCESS and FAILURE
3977 packets. They must be 32 bit MSB not 16 bit MSB.
3979 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Ok, rewrote the logic of the re-key and now it seems to work.
3982 I tested it on high traffic with frequent re-keys without
3983 problems. Added hmac_receive (and renamed hmac to hmac_send)
3984 in SilcClientConnection in lib/silcclient/client.h and
3985 in SilcIDListData in silcd/idlist.h. Also, removed the
3986 SilcPacketParserContext's cipher and hmac fields as they are
3987 not needed anymore and actually caused some problems when
3988 the ciphers and hmac's changed underneath the packet parser.
3990 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * If re-key protocol is active then process the incoming packets
3993 synchronously since we must assure that icoming packets encrypted
3994 with the old key is processed before the new keys is set to
3995 use. This is true other packets than for REKEY packets.
3996 Affected file silcd/server.c. The same was done to client library
3997 as well, affected file lib/silcclient/client.c.
3999 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed bug in client and server to accept the force send if
4002 the packet is send from silc_[server/client]_packet_process
4003 function. Otherwise the packets are never delivered, oops.
4005 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Disable force sending of packets when REKEY protocol is active.
4008 We must assure that no packet is sent directly when rekey is
4009 performed. All packets must be sent through packet queue.
4010 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4011 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4012 function is silc_[server/client]_packet_send_real to check
4015 * Replaced the SIM paths from example config files to
4016 /usr/local/modules. Also, make install creates now
4017 /usr/local/silc/logs directory to hold all the SILC server
4020 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Made the configure.in.pre work on Solaris. Patch by salo.
4024 * Made all ciphers compatible with non-x86 machines. Defined
4025 CBC mode macros into lib/silccrypt/ciphers_def.h.
4027 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Fixed the make install.
4031 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * When MAC computation fails the silc_packet_decrypt returned 0
4034 even though it was supposed to return -1. Fixed this. The
4035 affected file is lib/silccore/silcpacket.c.
4037 * Do not replace the config files in /etc/silc (in make install)
4038 if they already exist. Affected file ./Makefile.am.
4040 * Do not send re-key packets immediately but through packet queue.
4041 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4043 * Changed silc_net_check_host_by_sock to return FALSE if the
4044 IP/DNS could not be resolved. Though, it returns the IP address
4045 now even if it could not resolve it (but returns also FALSE).
4046 Affected file lib/silcutil/silcnet.[ch].
4048 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added silc_pkcs_decode_identifier to decode the public key's
4051 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4052 Added also silc_pkcs_free_identifier. Added also new context
4053 SilcPublicKeyIdentifier.
4055 * Added -S option to the silc client. It is used to dump the
4056 contents of the specified public key file.
4058 * Changed the PKCS api to return the public key length when
4059 setting the public key.
4061 * Fixed a fatal bug in the public and private key file loading.
4062 Affected file lib/silccrypt/silcpkcs.c.
4064 * Execute the packet parsing for client with zero (0) timeout
4065 if the protocol is active. Affected file silcd/server.c.
4067 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Made the key generation options to the silcd program. Added
4070 -C option, equivalent to client's option.
4072 * Added new [ServerKeys] config section to the server. It
4073 configures the server's public and private key.
4075 * Defined generic Public Key Payload into the protocol
4076 specification to send specific type of public keys and
4079 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4080 public key or certificate.
4082 * Implemented the GETKEY command to the server and to the
4083 client library and on user interface.
4085 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Made preliminary `make install' work.
4089 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added SilcServerRekey context into silcd/idlist.h.
4093 * Added the PFS support as defined in the specification to the
4094 SKE protocol. Affected files lib/silcske/*.c.
4096 * Added `ske_group' field to the SilcServerRekey context to hold
4097 the number of the SKE group that is used with PFS in re-key.
4098 Affected file silcd/idlist.h.
4100 * Added PFS re-key support to the server. Affected file is
4103 * Added silc_protocol_cancel to cancel execution of the next
4104 state of the protocol. Affected file is
4105 lib/silccore/silcprotocol.[ch].
4107 * Added the re-key support with and without PFS to the client
4108 library. Re-key is performed once in an hour, by default.
4110 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4111 Added silc_client_rekey_callback and silc_client_rekey_final.
4112 Affected files are lib/silcclient/protocol.[ch] and
4113 lib/silcclient/client.[ch].
4115 * Removed the `hmac_key' and `hmac_key_len' fields from the
4116 SilcClientConnection structure; not needed. Affected file is
4117 lib/silcclient/client.h.
4121 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Do not ask whether user wants to use the negotiated private key
4124 for private messages, just use it. Affected file is
4125 silc/local_command.c.
4127 * Added `send_enc_key' and `enc_key_len' fields to the
4128 SilcIDListData structure since they are needed in the re-key
4129 phase. Affected file is silcd/idlist.[ch].
4131 * Implemented the simple re-key protocol into the server.
4132 Affected files silcd/server.c and silcd/protocol.[ch]. The
4133 re-key will be performed once in an hour, by default.
4135 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4136 Added silc_server_rekey, silc_server_rekey_callback and
4137 silc_server_rekey_final.
4139 * Removed Tunneled flag from the protocol. Updated the code
4140 and the specifications.
4142 * Adde `pfs' field to the SilcIDListData to indicate whether
4143 the PFS is to be performed in the re-key. Affected file is
4146 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4149 int64 of at least the xintXX size. If void * is less that 4
4150 bytes uint32 * will be used. Defined bool as boolean.
4152 * Changed _ALL_ unsigned long and unsigned int to uint32,
4153 unsgined short to uint16 in the source tree.
4155 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4156 not handle clients that has entry->data.registered == FALSE.
4157 They are not in the network anymore. Affected file is
4160 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Implemented the sending of the SERVER_SIGNOFF notify in the
4163 server. Affected file is silcd/server.c.
4165 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4166 Added also silc_notify_payload_encode_args into the
4167 lib/silccore/silcnotify.[ch].
4169 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4170 Affected file silcd/packet_receive.c.
4172 * Implemented the SERVER_SIGNOFF notify handling in the client
4173 library. Affected file lib/silcclient/client_notify.c. Also,
4174 implemnted the printing of the SERVER_SIGNOFF info to the
4175 application. Affected file silc/client_ops.c.
4177 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4178 if the deleting was successful. Affected file silcd/idlist.[ch].
4180 * Added support for public key authentication in the connection
4181 authentication protocol in the client library. Affected file
4182 lib/silcclient/protocol.c.
4184 * Changed the server's silc_idlist_get_clients_by_* interface
4185 to support already allocated array so that new entries may be
4186 added to pre-allocated array. Affected file silcd/idlist.[ch].
4187 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4188 and command replies.
4190 * All command reply functions in the server now calls the
4191 pending command callback even if error occured. This way the
4192 error will be delivered to the client as well. Affected files
4193 silcd/command.c and silcd/command_reply.c.
4195 * Fixed INFO command to return local server's info if no server
4196 was provided. Affected file lib/silcclient/command.c.
4198 * Removed RESTART command for good. Updated the code and the
4201 * Rewrote parts of the task system. It is a bit simpler now.
4202 Removed unsued task priorities. The affected files are
4203 lib/silcutil/silctask.[ch].
4205 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Moved the USERS printing from the library to the application.
4208 Affected files lib/silcclient/command.c and silc/client_ops.c.
4210 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added channel key re-key support. The re-key is perfomed
4215 only by the router and is done once in an hour. Added `rekey'
4216 field to the SilcChannelEntry in the server. Affected files
4217 silcd/server.c and silcd/idlist.h.
4219 * Added silc_task_unregister_by_context into the file
4220 lib/silcutil/silctask.[ch].
4222 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added SILC_UMODE_GONE mode to indicate when the client is not
4225 present in the SILC network. Added also support to the local
4226 command AWAY that will set this mode. Added support of showing
4227 "xxx is gone" in WHOIS command. The USERS command shows the
4228 gone status as well.
4230 * Fixed setting server and router operator privileges in the
4231 server's UMODE command. Affected file silcd/command.c.
4233 * Merged the SKE KE1 and KE2 payloads into one payload. The
4234 new KE payload is equivalent to the old KE2 payload.
4236 Cleaned up the SKE Start Payload parsing. It now uses the
4237 simple buffer unformatting to do the parsing. A lot faster
4240 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4241 to the SKE that is used to indicate whether both of the SKE
4242 parties should perform authentication. By default only the
4243 responder performs authentication. By setting this flag also
4244 the initiator must do authentication. By default it is unset
4245 since in normal SKE case, client to server connection, only
4246 the responder should do authentication. When doing SKE between
4247 two clients both should perform authentication. Updated the
4248 code and the protocol specs.
4250 * A little fix to IDENTIFY command in the server. Search the
4251 client first by hash not nickname. Affected file is
4254 * Fixed the silc_client_close_connection to support closing
4255 the client to client connections wihtout deleting too much
4256 data. Affected file lib/silcclient/client.c.
4258 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4259 are received if protocol used to be active but is not anymore
4260 the application would crash due to NULL pointer dereference.
4261 Affected files silcd/server.c and lib/silcclient/client.c.
4263 * Added `hash' field to the SilcClientConnection to include
4264 the hash function negotiated in the SKE protocol.
4266 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4267 to set the channel founder authentication data. A client can
4268 claim the founder rights later by providing the authentication
4269 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4270 This way the channel founder can regain the channel founder
4271 privileges even it is left the channel. This works only on
4272 local server and the client must be connected to the same
4273 server to be able to regain the founder rights. Updated the
4274 protocol specs accordingly.
4276 Added support to the CMODE command in the client to set the
4277 founder auth data. Read the README to see how to set it.
4279 Added support to the CUMODE command to claim the founder
4280 rights. Read the README to see how to do it.
4282 Added support for the founder authentication to the Channel
4283 Entry in the server. Affected file silcd/idlist.h.
4285 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4286 server's CMODE command. Affected file silcd/command.c.
4288 * Added the following new functions into lib/silccore/silcauth.[ch]:
4289 silc_auth_get_method and silc_auth_get_data.
4291 * The server now saves the remote hosts public key to the
4292 SilcIDListData pointer. Affected file silcd/protocol.c.
4294 * The normal server now does not remove the channel entry from
4295 the cache if the founder authentication data is set. It used
4296 to remove it if the founder was the last one on the channel on
4297 the server and left the channel. The auth data is saved and
4298 if the channel is re-joined later the old entry is used with
4299 the old auth data. Affected files silcd/command_reply.c and
4302 * Removed the `pkcs' field from the SilcIDListData structure
4303 in the server; it is not used. Affected file silcd/idlist.h.
4305 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Fixed packet processing on slow links. Partial packets were
4308 never re-processed because the incoming data buffer was cleared
4309 by the application. Application must not directly clear the
4310 sock->inbuf, the packet processing routines handle it. Fixed
4311 this in client library and in server.
4313 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Fixed the WHOIS and IDENTIFY send reply function to really
4316 check whether to send list or just one entry. Affected file
4319 * Cleaned up the LEAVE command's channel key distribution. The
4320 affected file silcd/command.c.
4322 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4323 can enforce the channel mode as well. In that case the ID
4324 includes the ID of the server. The code now enforces the
4325 mode change if the router have different mode than the server.
4327 * The notify client operation with CMODE_CHANGE notify can now
4328 return NULL client_entry pointer if the CMODE was not changed
4329 by client. Application must check for this.
4331 * Added <Server ID> argument to INFO command to support server
4332 info fetching by Server ID.
4334 * Added silc_server_announce_get_channel_users to get assembled
4335 packets of channel users of the specified channel. Affected
4336 file silcd/server.[ch].
4338 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4339 was freed underneath the ID Cache.
4341 * Re-announce clients when the server received CHANNEL_CHANGE
4342 notify from the router. Affected file silcd/packet_send.c.
4344 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4347 crashed since it did not handle the fact that there is no cipher
4348 called "3" and didn't check the error condition. Now fixed.
4350 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4351 flag. It can be used to send message requests.
4353 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Implemented the RESTART command in the client.
4357 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4358 notice type messages. Added notice printing to the user
4361 * The channel keys are not re-generated if the channel's mode
4362 is PRIVKEY, ie private key on the channel exists. Affected
4363 files silcd/server.c and silcd/command.c.
4365 * Fixed a little bug in channel message delivery when channel
4366 private keys are set in the server. Affected file is
4367 silcd/packet_send.c.
4369 * Changed the setting on channel->on_channel = TRUE from the
4370 silc_client_save_channel_key to the JOIN command reply. The
4371 key payload is not received if the private channel key is set.
4372 Affected file lib/silcclient/command_reply.c and the
4373 lib/silcclient/client_channel.c.
4375 * When the CMODE_CHANGE notify is sent and the channel private
4376 key mode is removed the channel key must be re-generated in
4377 other cells as well. Added this support for the router in the
4378 silcd/packet_receive.c.
4380 * Added new local command NOTICE to send notice message on
4381 channel. Affected file silc/local_command.[ch].
4383 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Added new local command ME to the client. It is used to send
4386 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4387 some action. Affected file silc/local_command.[ch].
4389 * Changed channel_message and private_message client operations
4390 to deliver the message flags to the application. Added also
4391 the `flags' arguments to the silc_client_send_channel_message
4392 and silc_client_send_private_message functions. Affected file
4395 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Redefined the Private Message Payload to support private message
4398 keys and to support the new private message flags. Updated
4399 the protocol specs. Flags makes it possible to have for example
4400 CTCP style messages.
4402 * Added new type SilcPrivateMessagePayload and defined an API
4403 for it in the lib/silcclient/silcprivate.[ch].
4405 * Tested private message private keys successfully. Tested the
4406 private message key set, unset and list commands with the new
4409 * Redefined the Channel Message Payload to include the channel
4410 message flags (equal with private message flags) to support
4411 for example CTCP style messages.
4413 * Defined some of the message (for channel and private message)
4414 flags. Updated the protocol specs and added the flags to the
4415 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4417 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Added SilcKeyAgreementStatus type to the key agreement routines
4420 to indicate the current status and error if one occured.
4421 The status types are defined in the lib/silcclient/silcapi.h.
4423 * Added new local command KEY that is used to set and unset private
4424 keys for channels, set and unset private keys for private messages
4425 with remote clients and to send key agreement requests and
4426 negotiate the key agreement protocol with remote client. The
4427 key agreement is supported only to negotiate private message keys,
4428 it currently cannot be used to negotiate private keys for channels,
4429 as it is not convenient for that purpose.
4431 * Fixed a minor pending callback setting bug in the function
4432 silc_client_get_client_by_id_resolve, now the function works.
4433 Affected file lib/silcclient/idlist.c.
4435 * Added function silc_net_get_local_port to get local bound
4436 port by socket. Added to lib/silcutil/silcnet.[ch].
4438 * Added `sockets' and `sockets_count' fields to the SilcClient
4439 object. They hold the sockets of the listenning sockets in
4440 the client. Listenning sockets may be for example the key
4441 agreement server. Affected file lib/silcclient/client.[ch].
4442 Added functions the silc_client_add_socket and the
4443 silc_client_del_socket. They are exported to the application
4446 * Added ~./silc/clientkeys to support other client's public keys.
4448 * Renamed verify_server_key client operation to verify_public_key
4449 and added one argument to indicate the type of the connection
4450 (server, client etc.).
4452 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Added silc_server_connection_auth_request to handle the
4455 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4456 silcd/packet_receive.[ch].
4458 * Added silc_server_send_connection_auth_request into the
4459 silcd/packet_send.c to send the connection auth request packet.
4461 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4464 * Fixed the public key authentication in responder side in the
4465 server. The `auth_data' pointer includes the SilcPublicKey
4466 not the path to the public key. Affected file silcd/protocol.c.
4468 * Implemented the public key authentication in the initiator side
4469 in the server. Affected file silcd/protocol.c.
4471 * Removed the [RedirectClient] config section from the server
4472 configuration. Is not needed and I don't want to implement it.
4474 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Cleaned up the CMODE command in the server. It now works
4477 correctly and supports all the modes defined in the protocol.
4478 Affected file is silcd/command.c.
4480 * Added `hmac_name' field to the SilcChannelEntry in the server
4481 to hold the default HMAC of the channel. It can be set when
4482 creating the channel (with JOIN command). Affected files
4485 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4486 type to indicate the change of the current cipher and hmac
4487 on the channel. Client can safely ignore the <cipher> argument
4488 (if it chooses to do so) since the CHANNEL_KEY packet will
4489 force the channel key change anyway. The <hmac> argument is
4490 important since the client is responsible of setting the new
4491 HMAC and the hmac key into use.
4493 * Fixed the CMODE command in the client library as well.
4495 * Tested CMODE command in router environment successfully.
4497 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Show the version of the remote client (or server) when connecting
4500 to the server. It is logged to the log file. Affected file
4501 is silcd/protocol.c.
4503 * Fixed the KILLED notify handling in the client library. The
4504 client must be removed from all channels when receiving the
4507 Also, do not remove the client entry when giving the KILL
4508 command but when the KILLED notify is received.
4510 * Removed silc_idlist_find_client_by_nickname from the server.
4511 Not needed anymore. Affected files silcd/idlist.[ch].
4513 * Implemented the CHANNEL_CHANGE notify type handling to the
4514 server. Affected file silcd/server.c.
4518 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Added silc_server_send_notify_invite to send the INVITE
4521 notify between routers.
4523 * Implemented the INVITE command correctly to the server.
4525 * Implemented the INVITE notify type handling in the server.
4527 * Implemented the INVITE command to the client library and on the
4530 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added function silc_server_get_client_resolve to find the
4533 client entry by ID from all ID lists and then resolve it
4534 (using WHOIS) if it cannot be found. Affected file is
4537 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Implemented the BAN command to the client library.
4541 * The JOIN command in the server now checks the invite list
4544 * Changed the silc_command_reply_payload_encode_va and the
4545 silc_command_payload_encode_va to support that if argument is
4546 NULL it ignores and checks the next argument. Affected file
4547 lib/silccore/silccommand.c.
4549 * Added silc_server_send_notify_ban to send the BAN notify
4550 type between routers.
4552 * Chaned the silc_notify_payload_encode to support that if
4553 argument is NULL it ignores and checks the next argument.
4554 Affected file lib/silccore/silcnotify.c.
4556 * Tested ban lists in router environment successfully.
4558 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Implemented BAN command to the server, in silcd/command.[ch].
4562 * Removed the BAN and INVITE_LIST modes from the CMODE command
4565 * Added function silc_string_match to regex match two strings.
4566 Affected files lib/silcutil/silcutil.[ch].
4568 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Redefined parts of the SilcChannelEntry in the server to support
4571 the new ban and invite lists.
4573 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Redefined the INVITE command. The same command can be used to
4576 invite individuals to the channel but also to manage the invite
4577 list of the channel (to add to and remove from the invite list).
4578 Updated the protocol specs.
4580 * Added new command SILC_COMMAND_BAN that can be used to manage
4581 the ban list of the channel. Updated the protocol specs.
4583 * Removed the channel modes: the SILC_CMODE_BAN and the
4584 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4585 in the CMODE command. The equivalent features are now available
4586 using INVITE and BAN commands. Updated the protocol specs.
4588 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4589 in the network about change in the current ban list. The notify
4590 type is not used by the client.
4592 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4593 support the invite lists.
4595 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added new function silc_string_regexify that converts string
4598 including wildcard characters into regex string that can
4599 be used by the GNU regex library. Added into the file
4600 lib/silcutil/silcutil.[ch].
4602 Added silc_string_regex_combine to combine to regex strings
4603 into one so that they can be used as one regex string by
4604 the GNU regex library. Added into the file
4605 lib/silcutil/silcutil.[ch].
4607 Added silc_string_regex_match to match two strings. It returns
4608 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4610 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Imported GNU regex to the soruce tree into lib/contrib.
4613 Fixed some compiler warning from the regex.c.
4615 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Fixed MOTD command in the server to work in router environment.
4619 * Fixed the MOTD command in the client library to support
4620 the server argument in the command.
4622 * Added `nickname_len' argument to the silc_idlist_add_client
4623 in the server, as the `nickname' argument may be binary data
4626 * Added silc_idlist_get_channels to return all channels from
4629 * Implemented LIST command to the server. Affected file is
4632 * Implemented the LIST command to the client library and on the
4635 * Added [<user count>] argument to the LIST command reply.
4636 With private channels the user count is not shown.
4638 * Updated TODO and README.
4640 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * The client entry's data.registered must be TRUE even with
4643 global client entry on global client list. The data.registered
4644 is used to check whether the client is anymore in the network,
4645 for example with WHOWAS command so it must be valid.
4647 * Fixed the WHOWAS command in the server. It now actually works
4648 in router environment. Added function into silcd/command_reply.c
4649 silc_server_command_reply_whowas_save.
4651 * Added silc_idlist_purge function to the silcd/idlist.c
4652 to periodically purge the ID Cache.
4654 * Fixed INFO command in the server. It works now in router
4655 environment. Added <server name> argument to the INFO command
4656 reply. Updated the protocol specs.
4658 * Fixed minor bug in silc_idcache_purge to not purge if the
4659 expire value is zero.
4661 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4662 they were buggy because of the WHOWAS information.
4664 * Fixed local command MSG to handle the async resolving of
4665 the remote client properly. It used to fail the first MSG.
4666 Affected file silc/local_command.c.
4668 * Added `data_len' field to SilcIDCache context.
4670 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Update TODO. Todo in commands in the server.
4674 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4677 used by routers as broadcast packet to inform other routers
4678 about the changed user mode.
4680 Implemented the notify handling in the server. Affected file is
4681 silcd/packet_receive.c. Added the function
4682 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4684 * Added new generic Channel Payload and deprecated the New Channel
4685 Payload. The New Channel Payload is now the generic Channel
4688 * Added new argument `mode' to the silc_server_send_new_channel
4689 as it is required in the Channel Payload now.
4691 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4692 and created a new and real SilChannelPayload to represent the
4693 new generic Channel Payload. Implemented the encode/decode
4694 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4696 * Added silc_server_get_client_channel_list to return the list
4697 of channels the client has joined for WHOIS command reply.
4698 Affected file silcd/server.[ch].
4700 * Implemented the channel list sending in the WHOIS command reply
4701 in server and in the client.
4703 Implemented the channel list displaying on the user interface
4704 as well. Affected file silc/client_ops.c.
4706 * Added silc_channel_payload_parse_list to parse list of Channel
4707 Payloads. It returns SilcDList list of SilcChannelPayloads.
4708 Client for example can use this function to parse the list of
4709 channels it receives in the WHOIS command reply. The caller
4710 must free the list by calling silc_channel_payload_list_free.
4711 Affected files lib/silccore/silcchannel.[ch].
4713 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added one new argument <user mode> to the WHOIS command reply
4716 to return the mode of the user in SILC. Updated the protocol
4719 Implemented it to the server and client.
4721 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Fixed the mode printing on the user interface on joining.
4724 Affected file silc/client_ops.c.
4726 * Implemented the UMODE command and user modes in general to the
4727 client library and to the user interface.
4729 * Implemented the UMODE command to the server.
4731 * The server now sends UNKNOWN_COMMAND error status if client sends
4732 unknown command. Affected file silcd/command.c.
4734 * All server commands now handle the command identifier the right
4735 way when sending the command reply to the client. The client can
4736 use to identify the command replies with the identifier.
4738 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added silc_server_get_client_route to resolve the route to
4741 the client indicated by the client ID. Affected file is
4744 * Added silc_server_relay_packet as general function to relay
4745 packet to arbitrary destination. This deprecates functions
4746 like _send_private_message_key, _relay_notify etc. Affected
4747 file is silcd/packet_send.[ch].
4749 Removed silc_server_send_key_agreement,
4750 silc_server_send_private_message_key and
4751 silc_server_packet_relay_notify functions from the file
4752 silcd/packet_send.[ch].
4756 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4757 server. Affected file silcd/packet_receive.[ch].
4759 * Implemented the KILL command to the client. Implemented the
4760 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4761 Affected files lib/silcclient/command[_reply].c and
4762 lib/silcclient/client_notify.c. Implemented the KILL notify
4763 printing in the user inteface.
4765 * Fixed a lot silc_parse_nick memory leaks from the client
4766 library in the file lib/silcclient/command.c.
4768 * Changed the silc_server_send_notify_on_channels's `sender'
4769 argument from SilcSocketConnection to SilcClientEntry to
4770 check the sender as entry and not as connection object and not
4771 to send to the client provided as argument. The affected file
4772 is silcd/packet_send.[ch].
4774 * The notify packets that are destined directly to the client used
4775 to not to be processed by the server. Now changed that and the
4776 server processes all notify packets. After relaying the packet
4777 to the client the notify packet is processed in the server.
4779 * The silc_server_free_client_data now checks whether there is
4780 pending outgoing traffic for the client and purges the data to
4781 the network before removing the client entry.
4783 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4786 an client is killed from the SILC Network. Updated the protocol
4789 Added new function silc_server_send_notify_killed to the
4790 silcd/packet_send.[ch].
4792 * Added function silc_server_packet_relay_notify to relay notify
4793 packets that are destined directly to a client. In this case
4794 the server does not process the notify packets but merely relays
4795 it to the client. Affected file silcd/packet_send.[ch].
4797 Added also silc_server_packet_process_relay_notify to check
4798 whereto relay the notify. Affected file is
4799 silcd/packet_receive.[ch].
4801 * Implemented the KILL command to the server.
4805 * Added the backup schema desgined last fall to the protocol
4806 specs for everyone to see. The specification is in the
4807 *-spec-xx.txt draft and the packet type definitions for the
4808 backup routers is in *-pp-xx.txt draft. Thusly, added also
4809 new packet type SILC_PACKET_CELL_ROUTERS.
4811 * A big security problem in the implementation discovered. The
4812 signoff of an client did not cause new channel key generation
4813 which it of course should've done. The channel keys must be
4814 always re-generated when client leaves (or signoffs) the channel.
4815 The silc_server_remove_from_channels funtion now handles
4816 the channel key re-generation.
4818 * Added `sender' argument to the silc_server_send_notify_on_channels
4819 to not to send the client provided as argument. Affected file
4820 silcd/packet_send.[ch].
4822 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Implemented OPER and SILCOPER commands into the server and
4827 * Added silc_auth_verify and silc_auth_verify_data to verify
4828 the authentication directly from the authentication payload.
4829 It supports verifying both passphrase and public key based
4830 authentication. Affected file lib/silccore/silcauth.[ch].
4832 * Added `hash' field to the SilcIDListData structure. It is the
4833 hash negotiated in the SKE protocol. Affected file is
4836 * Slight redesigning of the SilcAuthPayload handling routines.
4837 Do not send SilcPKCS but SilcPublicKey as argument.
4839 * Implemented the public key authentication support to the
4840 serverconfig. The public key is loaded from the provided path
4841 and saved as authentication data to void * pointer. Thus,
4842 changed the unsigned char *auth_data to void *auth_data;
4844 * Fixed SHUTDOWN command to send the reply before the server
4845 is shutdown. :) Affected file silcd/command.c.
4847 * Fixed fatal bug in CONNECT command. The hostname was invalid
4848 memory and server crashed. Affected file silcd/command.c.
4850 * Fixed fatal bug in CLOSE command. The server_entry became
4851 invalid but was referenced later in the command. Affected file
4854 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Fixed fatal bug in failure packet handling. Server ignored
4857 the failure and thus crashed when it came.
4861 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4864 that the command may be executed only once in (about) 2 seconds.
4865 The old SILC_CF_LAG flag is same but allows command bursts up
4866 to five before limiting.
4868 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4869 server code. Various commands now includes the CF_LAG_STRICT
4870 flag to disallow any kind of miss-use of the command.
4872 * Fixed the silc_buffer_unformat to not to allocate any data
4873 if the length of the data is zero. It used to allocate the
4874 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4876 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Changed the format of AdminConnection configuration section
4879 in the server. Added username of the admin to the format.
4880 Affected files silcd/serverconfig.[ch].
4882 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4883 to return admin configuration data by host, username and/or
4886 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Implemented WHOWAS command to the server. Added the functions:
4890 silc_server_command_whowas_parse,
4891 silc_server_command_whowas_send_reply,
4892 silc_server_command_whowas_from_client and
4893 silc_server_command_whowas_from_server
4895 * Added <Client ID> argument to the WHOWAS command reply. Updated
4896 the protocol specs accordingly.
4898 * Implemented WHOWAS command and command_reply to the client
4901 Implemented the WHOWAS printing on the user interface.
4903 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added new argument to the WHOWAS command reply, the real name.
4906 It is an optional argument. Updated the protocol specs.
4908 * Added SilcIDCacheDestructor callback that is registered when
4909 the SilcIDCache is allocated. The callback is called when
4910 an cache entry in the ID Cache expires, or is purged from the
4911 cache. Added into lib/silccore/idcache.[ch].
4913 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4914 to destruct the client entries when the cache entry expires.
4915 Other ID Cache's in server and in the client library ignores
4918 * If the ID Cache entry's `expire' field is zero then the entry
4919 never expires. Added boolean `expire' argument to the
4920 silc_idcache_add function in the lib/silccore/idcache.[ch].
4921 If it is TRUE the default expiry value is used.
4923 * Added silc_server_free_client_data_timeout that is registered
4924 when client disconnects. By default for 5 minutes we preserve
4925 the client entry for history - for WHOWAS command.
4927 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Added support to the server to enforce that commands are not
4930 executed more than once in 2 seconds. If server receives
4931 commands from client more frequently, timeout is registered
4932 to process the commands. Affected file silcd/command.c.
4933 Added new function silc_server_command_process_timeout.
4935 * Changed NICK_NOTIFY handling in client library to check that
4936 if the client's nickname was changed, so there is no need to
4937 resolve anything from the server.
4939 * Removed error printing from the WHOIS and IDENTIFY commands.
4940 If error occurs then it is ignored silently in the client library.
4941 The application, however, may map the received error to
4942 human readable error string. The application currently maps
4943 the NO_SUCH_NICKNAME error to string.
4945 * Made the command status message public to the application. Moved
4946 them from lib/silcclient/command_reply.c to
4947 lib/silcclient/command_reply.h. The application can map the
4948 received command status to the string with the
4949 silc_client_command_status_message function.
4951 * Added check to the server to check that client's ID is same
4952 as the Source ID in the packet the client sent. They must
4955 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Added dist-bzip hook to the Makefile.am to make bzip2
4958 compressed distributions.
4960 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Server now enforces the maximum length for the nickname and
4963 the channel as protocol specification dictates. 128 bytes for
4964 nickname and 256 bytes for channel name.
4966 * Moved the WHOIS printing to the application. The client libary
4967 does not print out the WHOIS information anymore, the application
4968 must do it. Renamed silc_client_command_reply_whois_print to
4969 the silc_client_command_reply_whois_save.
4971 The client's idle time is also sent to the application now, and
4972 the idle is shown on screen.
4974 * Added silc_client_command_reply_identify_save to save the
4975 received IDENTIFY entries.
4977 * Do not check for channel private keys in message sending and
4978 reception if the channel does not have the PRIVKEY mode set.
4979 Affected file lib/silclient/client_channel.c.
4981 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4984 just surfaced after chaning the JOIN procedure.
4986 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Added silc_client_get_clients_by_list to get client entries
4989 from Client ID list, that is returned for example by JOIN
4990 and USERS command replies. The application should use this
4991 function for example when JOIN command reply is received to
4992 resolve the clients already on the channel (library does not
4993 do that anymore as USERS command reply is not used in the JOIN
4994 procedure anymore). Affected files lib/silcclient/silcapi.h and
4995 lib/silcclient/idlist.c.
4997 * JOIN command reply and USERS command reply returns now SilcBuffer
4998 pointers instead of unsigned char pointers when returning
4999 the client list and mode list.
5001 * Added <Client ID> argument to the JOIN command reply, mainly
5002 for the server to identify for which client the command was
5003 originally sent. Updated protocol specs accordingly.
5005 * Added SilcDlist private_key pointer to the SilcChannelEntry
5006 in the client to support the channel private keys. Affected
5007 file is lib/silcclient/idlist.h.
5009 * Added SilcChannelPrivateKey argument to the function
5010 silc_client_send_channel_message so that application can choose
5011 to use specific private ke if it wants to. If it is not provided,
5012 the normal channel key is used, unless private keys are set.
5013 In this case the first (key that was added first) is used
5014 as the encryption key.
5016 * Implemented the support for channel private key handling.
5017 Implemented the following functions:
5019 silc_client_add_channel_private_key,
5020 silc_client_del_channel_private_keys,
5021 silc_client_del_channel_private_key,
5022 silc_client_list_channel_private_keys and
5023 silc_client_free_channel_private_keys
5025 Affected file lib/silcclient/client_channel.c.
5027 * Added the support for the private keys in the channel message
5028 sending and encryption and in the message reception and
5029 decryption. Affected funtions are
5030 silc_client_send_channel_message and silc_client_channel_message.
5032 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Added SKE's key verify callback to the client library's
5035 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5037 * Removed the statement that server (or router) must send USERS
5038 command reply when joining to the channel so that the client
5039 knows who are on the channel. Instead, the client list and
5040 client's mode list is now sent in the JOIN command reply to the
5041 client who joined channel. This is better solution.
5043 * Added function silc_server_get_users_on_channel and function
5044 silc_server_save_users_on_channel to the silcd/server.[ch].
5046 * Removed function silc_server_command_send_users from the
5049 * Do not show topic on the client library anymore. The topic is
5050 sent in the command reply notify to the application and the
5051 application must show the topic now.
5053 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Added client searching by nickname hash into the IDENTIFY and
5056 WHOIS commands in the server as they were clearly missing from
5057 them. Affected file is silcd/command.c.
5059 * Fixed a bug in private message receiving in the client library.
5060 The remote ID was freed and it wasn't supposed, now it is
5063 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Minor fix to the channel payload; allocate the data area, as it
5066 needs to be of specific length.
5068 * If the key agreement port is zero then the operating
5069 system will define the bound port. Affected files are
5070 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5072 * Added new function silc_channel_payload_decrypt into the file
5073 lib/silccore/silcchannel.[ch].
5075 * Moved the channel message etc, check from silc_packet_decrypt
5076 to applications. The library calls now a generic
5077 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5078 when the packet is either normal or special. This was done to
5079 allow more wide range of checking that was not allowed when
5080 the code was in library. Now applications can do virtually any
5081 checks to the packet and return to the library the decision how
5082 the packet should be processed. Affected files are
5083 lib/silccore/silcpacket.[ch].
5085 Added silc_server_packet_decrypt_check to the server and
5086 silc_client_packet_decrypt_check to the client library.
5088 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5089 to send with specified source and destination information.
5091 * Channel message delivery between routers was broken after the
5092 channel key distribution was fixed earlier. The channel key
5093 was used be to distributed to other routers as well which is not
5094 allowed by the protocol. Now this is fixed and channel keys
5095 really are cell specific and the channel message delivery between
5096 routers comply with the protocol specification.
5098 * Fixed various commands in server to check also the global list
5099 for the channel entry and not just the local list. The affected
5100 file silcd/command.c.
5102 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Added assert()s to buffer formatting and unformatting routines
5105 to assert (if --enable-debug) when error occurs. Affected
5106 file: lib/silcutil/silcbuffmt.c.
5108 * Changed to auto-reconnect to check whether the remote host is
5109 router and register the re-connect timeout if it is. It used
5110 to check that whether we are normal server, but router must do
5111 auto-reconnect with another router as well. Affected file
5114 * Removed the [<key len>] option from CMODE command as the cipher
5115 name decides the key length, nowadays. See the defined ciphers
5116 from the protocol specification.
5118 * Added [<hmac>] option to the CMODE command to define the HMAC
5119 for the channel. Added SILC_CMODE_HMAC channel mode.
5121 * Added [<hmac>] option for the JOIN command so that user can
5122 select which HMAC is used to compute the MACs of the channel
5125 * Added Hmac field to the Channel Message Payload. The integrity
5126 of plaintext channel messages are now protected by computing
5127 MAC of the message and attaching the MAC to the payload. The
5128 MAC is encrypted. Now, it is clear that this causes some
5129 overhead to the size of the packet but rationale for this is that
5130 now the receiver can verify whether the channel message decrypted
5131 correctly and also when private keys are set for the channel the
5132 receiver can decrypt the packet with several keys and check from
5133 the MAC which key decrypted the message correctly.
5135 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5136 lib/silccrypt/silccipher.[ch].
5138 * Added silc_hash_len to return the digest length into the
5139 lib/silcrypt/silchash.[ch].
5141 * Rewrote parts of Silc Channel Payload interface in the
5142 lib/silccore/silcchannel.[ch]. The encode function now also
5143 encrypts the packet and parse function decrypts it.
5145 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Fixed a minor formatting bug in the SKE's key material processing.
5148 It actually might have processed the keys wrong way resulting
5151 * Redefined the mandatory HMAC algorithms and added new algorithms.
5152 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5153 and hmac-md5 truncated to 96 bits. The mandatory is now
5154 hmac-sha1-96. Rest are optional (including the one that used
5155 to be mandatory). Rationale for this is that the truncated HMAC
5156 length is sufficient from security point of view and can actually
5157 make the attack against the HMAC harder. Also, the truncated
5158 HMAC causes less overhead to the packets. See the RFC2104 for
5161 * Added new [hmac] configuration section. The SKE used to use
5162 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5163 is of course wrong. The official names that must be proposed in
5164 the SKE are the ones defined in the protocol specification
5165 (hmac-sha1-96 for example). The user can configure any hmac
5166 using any hash function configured in the [hash] section. At
5167 least, the mandatory must be configured.
5169 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5171 * Added HMAC list to the SKE proposal list. It has now both
5172 hash algorithm list and HMAC list. This makes the protocol
5173 incompatible with previous versions. The SKE now seems to work
5174 the way it is supposed to work, for the first time actually.
5176 * Defined plain Hash algorithms to the protocol specification.
5179 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Implemented support for key agreement packets into the server.
5182 Added functions silc_server_key_agreement and
5183 silc_server_send_key_agreement. Other than these functions,
5184 server has nothing to do with this packet.
5186 * Added support for private message key packets into the server.
5187 Added functions silc_server_private_message_key and
5188 silc_server_send_private_message_key.
5192 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5193 called in the protocol's final callback instead in the END
5194 protocol state. This makes a little more sense and in the same
5195 time in client we can use the same protocol routines for normal
5196 key exchange and to key agreement packet handling as well.
5198 * Added to both client's and server's KE protocol context the
5199 SilcSKEKeyMaterial pointer to save the key material. We will
5200 bring the key material to the protocol's final callback by doing
5201 this. The final callback must free the key material.
5203 * Added SKE's packet_send callback into client's KE protocol
5204 context so that the caller can choose what packet sending function
5205 is used. This way we can use different packet sending when
5206 doing normal SKE when doing key agreement packet handling (in
5207 the key agreement packet handling we do not want to encrypt
5210 * Implemented the responder side of the key agreement routines
5211 in the client. The client can now bind to specified port and
5212 accept incoming key negotiation. The key material is passed
5213 to the application after the protocol is over.
5215 * Implemented the processing of incoming Key Agreement packet
5216 in the client. Added function silc_client_key_agreement to
5219 * Implemented the intiator side of the key agreement routines
5220 in the client. The client can now initiate key agreement with
5221 another remote client. The key material is passed to the
5222 application after the protocol is over.
5224 * Created client_keyagr.c to include all the key agreement
5227 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5228 SILC_TASK_CALLBACK except that it is not static.
5230 * Created client_notify.c and moved the Notify packet handling
5231 from the client.[ch] into that file.
5233 * Created client_prvmsg.c and moved all private message and
5234 private message key routines from the client.[ch] into that file.
5236 * Create client_channel.c and moved all channel message and
5237 channel private key routines from the client.[ch] into that file.
5239 * Changed silc_client_get_client_by_id_resolve to resolve with
5240 WHOIS command instead of IDENTIFY command, in the file
5241 lib/silclient/idlist.c.
5243 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Implemented the SKE's responder side to the Client library.
5247 * When FAILURE is received to the protocol do not trust it
5248 blindly. Register a timeout to wait whether the remote closes
5249 the connection as it should do it, only after that process the
5250 actual failure. This was changed to both client and server.
5252 * Added client_internal.h to include some of the structures
5253 there instead of client.h in lib/silcclient/.
5255 * Added function silc_task_unregister_by_callback to unregister
5256 timeouts by the callback function.
5258 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Some "Incomplete WHOIS info" errors has been appearing on the
5261 log files. Took away the entry->userinfo check from WHOIS
5262 reply sending. The entry->userinfo is now " " if client did not
5263 provide one. I thought this was fixed earlier but something
5264 is wrong still. Let's see if the error still appears.
5266 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed a minor bug in the login when the channel key is
5269 re-generated in the server. It used to generate the key in
5270 wrong order and thus caused problems in the channel traffic.
5272 * Fixed a minor bug in channel key distsribution after
5273 KICK command. The key was not sent to the router even though
5276 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Added silc_ske_process_key_material_data as generic routine
5279 to process any key material as the SILC protocol dictates. The
5280 function is used by the actual SKE library but can be used by
5281 applications as well. This relates to the private message keys
5282 and the channel private keys since they must be processed the
5283 same way the normal SILC session keys. The protocol dictates
5284 this. Affected files: lib/silcske/silcske.[ch].
5286 Added also silc_ske_free_key_material to free the
5287 SilcSKEKeyMaterial structure.
5289 * Defined silc_cipher_set_key function to set the key for
5290 cipher without using the object's method function. The affected
5291 files: lib/silccrypt/silccipher.[ch].
5293 * Implemented silc silc_client_add_private_message_key,
5294 silc_client_add_private_message_key_ske,
5295 silc_client_del_private_message_key,
5296 silc_client_list_private_message_keys and
5297 silc_client_free_private_message_keys functions in the
5300 Added functions silc_client_send_private_message_key to send
5301 the Private Message Key payload and silc_client_private_message_key
5302 to handle incoming Private Message Key payload.
5304 * Added Cipher field to the Private Message Key payload to set
5305 the cipher to be used. If ignored, the default cipher defined
5306 in the SILC protocol (aes-256-cbc) is used.
5308 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Removed lib/silcclient/ops.h file.
5312 Redefined parts of the SILC Client Library API. Created new
5313 file silcapi.h that deprecates the ops.h file and defines the
5314 published Client Library API. Defined also private message key
5315 API and channel private key API into the file.
5317 This is the file that the application must include from the
5318 SILC Client Library. Other files need not be included by
5319 the application anymore.
5321 * Added new key_agreement client operation callback and also
5322 defined the Key Agreement library API for the application.
5324 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5327 is used by clients to request key negotiation between another
5328 client in the SILC network. If the negotiation is started it
5329 is performed using the SKE protocol. The result of the
5330 negotiation, the secret key material, can be used for example
5331 as private message key.
5333 Implemented the Key Agreement payload into the files
5334 lib/silccore/silauth.[ch].
5336 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Redefined ciphers for the SILC protocol. Added some new ciphers
5339 and defined the key lengths for the algorithms. Changed the
5340 code accordingly. The default key length is now 256 bits.
5342 * Fixed SKE key distribution function silc_ske_process_key_material
5343 when the key length is more than 128 bits. The default key
5344 length in SILC is now 256 bits.
5346 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5347 to indicate unsupported algorithm.
5349 * Renamed rijndael.c to aes.c and all functions as well.
5351 * Fixed a long standing channel key setting bug in client library.
5352 Weird that it has never surfaced before.
5354 * Fixed bug in channel deletion. If the entire channel is removed
5355 then it must also delete the references of the channel entry
5356 from the client's channel list as the client's channel entry and
5357 the channel's client entry share same memory.
5359 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Implemented CONNECT and SHUTDOWN commands in the client.
5363 * Implemented CLOSE command to the client.
5365 * Added the function silc_idlist_find_server_by_name into the
5366 files silcd/idlist.[ch].
5368 Added the function silc_idlist_find_server_by_conn into the
5369 files silcd/idlist.[ch].
5371 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * DIE command was renamed to SHUTDOWN. Updated the both code
5376 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5377 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5379 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5382 * Added function silc_server_create_connection function to create
5383 connection to remote router. My server implementation actually
5384 does not allow router to connect to normal server (it expects
5385 that normal server always initiates the connection to the router)
5386 so the CONNECT command is only good for connecting to another
5389 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5392 or some other client was kicked from the channel.
5394 Implemented the handling of the notify type to both client
5397 Implemented silc_server_send_notify_kicked to send the KICKED
5398 notify. It is used to send it to the server's primary router.
5400 * Implemented the KICK command into server and client.
5402 * Added `query' argument to the silc_idlist_get_client function
5403 to indicate whether to query the client from server or not if
5406 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5407 to indicate that the client is not channel founder.
5411 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Removed the rng context from SilcPacketContext structure and
5414 changed that the packet routine uses the Global RNG API.
5416 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Added support for quit message that client can "leave" on the
5419 channel when it quits the SILC. It is ditributed inside the
5420 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5422 Added silc_server_free_client_data that will take the
5423 signoff message as argument.
5425 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5427 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Updated parts of the protocol specification to keep it up
5432 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5435 payloads in one packet.
5437 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5438 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5439 use now the new List flag.
5441 * Also deprecated the following packet types: REPLACE_ID,
5442 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5444 * Added list support for Notify packet in server.
5446 * Added silc_server_send_notify_channel_change to send the
5447 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5448 the silc_server_send_replace_id.
5450 * Added silc_server_send_notify_nick_change to send the
5451 NICK_CHANGE notify type. Deprecates the function
5452 silc_server_send_replace_id.
5454 * Added silc_server_send_notify_join to send the JOIN notify type.
5455 Deprecates the function silc_server_send_new_channel_user.
5457 * Added silc_server_send_notify_leave to send LEAVE notify type.
5458 Deprecates the function silc_server_send_remove_channel_user.
5460 * Added silc_server_send_notify_cmode and
5461 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5462 types. Deprecates the silc_server_send_set_mode function.
5464 * Added SERVER_SIGNOFF notify type to indicate that server has
5465 quit. This means that all clients on the channel from that
5466 server will drop. This can be also used when netsplit happens.
5468 Deprecated REMOVE_ID packet type since it is not needed anymore
5471 Added silc_server_send_notify_server_signoff to send the
5472 SERVER_SIGNOFF notify type. Deprecates the function
5473 silc_server_send_remove_id.
5475 Added also silc_server_send_notify_signoff to send the
5476 SIGNOFF notify type.
5478 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5479 SILC protocol from this day on. Changed the protocol
5480 specification as well.
5482 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5483 notify type. It is used between routers to notify about
5484 topic changes on a channel.
5486 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5489 * Partly updated the protocol specification to comply with the
5490 changes now made. It is still though a bit outdated.
5492 * The JOIN notify type now takes one extra argument <Channel ID>.
5493 The packet used to be destined to the channel but now the
5494 JOIN type may be sent as list thus it is impossible to
5495 destine it to any specific channel. By adding this argument
5496 it is again possible.
5498 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added CREDITS file. The CHANGES and CREDITS file will appear
5501 in the distribution as well.
5503 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5506 types in the server's silcd/packet_receive.c.
5508 * Implemented CMODE and CUMODE to work in router environment.
5510 * Fixed minor encoding and decoding buglet from the
5511 lib/silccore/silcmode.c.
5513 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5516 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5518 * Changed all SilcConfigServer* and silc_config_server* to
5519 SilcServerConfig* and silc_server_config*, respectively.
5522 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Associated the ID (client or server ID) to the Authentication
5525 Payload to avoid any possibility of forging. Updated the
5526 protocol specification and the code accordingly.
5528 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * The RSA key length is now save to the RsaKey context in the
5531 key generation process in lib/silccrypt/rsa.c. The key length
5532 is now used to figure out the maximum size of the block allowed
5533 to be encrypted/signed.
5535 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5536 is equivalent to the silc_mp_mp2bin but does not allocate any
5539 * Changed silc_mp_mp2bin API to take length argument. If it is
5540 non-zero then the buffer is allocated that large. If zero, then
5541 the size is approximated using silc_mp_sizeinbase, which however
5544 * Created Global RNG API which is global RNG that application can
5545 initialize. After initializing, any routine anywhere in the
5546 code (including library) can use RNG without allocating a new
5547 RNG object. This was done to allow this sort of use of the
5548 RNG in code that has no chance to allocate RNG object. All
5549 applications currently allocate this and many routines in the
5550 library use this. Affected file lib/silccrypt/silcrng.[ch].
5552 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5553 it to use the Global RNG API.
5555 * Defined Authentication Payload into protocol specification that
5556 is used during SILC session to authenticate entities. It is
5557 used for example by client to authenticate itself to the server
5558 to obtain server operator privileges.
5560 Implemented this payload into the lib/silccore/silcauth.[ch].
5561 Implemented also routines for public key based authentication
5562 as the new protocol specification dictates.
5564 Moved definitions of different authentication methods from
5565 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5567 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5568 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5569 silc_pkcs_verify_with_hash functions into the file
5570 lib/silccrypt/silcpkcs.[ch].
5572 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * The client entry's userinfo pointer must be always valid.
5575 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5576 will fail since it requires the userinfo. Now, the userinfo
5577 is allocated as "" if actual userinfo does not exist. Actually,
5578 it must exist and it is totally Ok to drop client connections
5579 that does not announce the userinfo. However, we will make
5580 this workaround for now.
5582 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5583 to return the remote port by socket.
5585 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5588 SILC_SERVER_PENDING_EXEC and added an new macro
5589 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5590 data or when error occurs while processing the pending command.
5592 Added new argument `destructor' into silc_server_command_pending
5593 and to the SilcServerCommandPending object. This destructor is
5594 now called after calling the pending callback or if error occurs
5595 immediately. If error occurs the actual pending callback won't
5596 be called at all - only the destructor. The destructor may be
5597 NULL if destructor is not needed.
5599 All this applies for client library code as well. Similar
5600 changes were made there as well for the pending commands.
5602 In the client, the application must now allocate the
5603 SilcClientCommandContext with the silc_client_command_alloc
5606 * Added reference counter to the SilcServerCommandContext. Added
5607 function silc_server_command_alloc and silc_server_command_dup
5610 Same type of functions added to the client library for the same
5613 * Removed the cmd_ident from IDListData away since it is now
5614 global for all connections. It is the command identifier used
5615 in command sending and with pending commands. The affected file
5618 * Added reference counter to the SilcSocketConnection objecet to
5619 indicate the usage count of the object. The object won't be
5620 freed untill the reference counter hits zero. Currently only
5621 server uses this, and client ignores it. The client must be
5622 set to use this too later. The affected files are
5623 lib/silccore/silcsockconn.[ch]. Added also the function
5624 silc_socket_dup to increase the reference counter.
5626 This was mainly added because it is possible that the socket
5627 is removed underneath of pending command or other async
5628 operation. Now it won't be free'd and proper DISCONNECTING
5629 flags, etc. can be set to avoid sending data to connection that
5630 is not valid anymore.
5632 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5633 the connection. After that it sets SILC_SET_DISCONNECTED.
5634 It is, however, possible that the socket data is not still freed.
5635 The silc_server_packet_process now checks that data is not
5636 read or written to connection that is DISCONNECTED. The socket
5637 get's freed when the reference counter hits zero.
5639 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Changed the client operation API: channel_message operation's
5642 `sender' is now the client entry of the sender, not the nickname
5643 and the `channel' is the channel entry, not the channel name.
5645 In the private_message operation the `sender' is now also the
5646 client entry of the sender not the nickname.
5648 Affected file is lib/silcclient/ops.h and all applications
5649 using the client operations.
5651 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Moved the calling of ops->connect() from connect_to_server_final
5654 into receive_new_id functin since that is the point when the
5655 client is actually allowed to send traffic to network. The
5656 affected file is lib/silcclient/client.c.
5658 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5661 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5662 (if needs broadcasting) instead of broadcasting the packets one
5663 by one which would make a burst in the network traffic.
5665 * Added `broadcast' argument to the functions in silcd/server.[ch]
5666 silc_server_create_new_channel[_with_id] to indicate whether
5667 to send New Channel packet to primary router.
5669 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added new function into the silcd/server.[ch] files:
5672 silc_server_create_new_channel_with_id to create new channel with
5673 already existing Channel ID.
5675 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5676 lib/silccore/silcpacket.h. This packet is used t send list of
5677 Set Mode payloads inside one packet. Server uses this to set
5678 the modes for the channels and clients on those channels, that it
5679 announced to the router when it connected to it. The protocol
5680 specification has been updated accordingly.
5682 * The silc_server_new_channel did not handle the packet coming
5683 from normal server as it normally does not send that. However,
5684 when it announces its channels it does send it. Implemented
5685 the support for that.
5687 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5688 into the file lib/silccore/id.h.
5690 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Fixed memory leaks in the functions silc_idlist_del_client,
5693 silc_idlist_del_channel and silc_idlist_del_server in the file
5694 silcd/idlist.c. All of those leaked like a sieve.
5696 * Fixed some small memory leaks in the client's function
5697 silc_client_notify_by_server.
5699 * Added functions into silcd/server.c: silc_server_announce_clients,
5700 silc_server_announce_channels and silc_server_announce_server.
5701 These functions are used by normal and router server to announce
5702 to its primary router about clients, channels and servers (when
5703 router) that we own. This is done after we've connected to the
5706 These functions effectively implements the following packet types:
5707 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5708 and SILC_PACKET_NEW_ID_LIST.
5710 * Added new functions into the silcd/packet_receive.[ch]:
5711 silc_server_new_id_list, silc_server_new_channel_list and
5712 silc_server_new_channel_user_list to handle the incoming
5713 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5715 * Added support of changing Channel ID in the function
5716 silc_server_replace_id. If the server that announces a channel
5717 to the router already exists in the router (with same name but
5718 with different Channel ID), router is responsible to send
5719 Replace ID packet to the server and force the server to change
5720 the Channel ID to the one router has.
5722 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5723 client that the Channel ID has been changed by the router. The
5724 normal server sends this to the client. Client must start using
5725 the new Channel ID as the channel's ID.
5727 Implemented handling of this new type into lib/silcclient/client.c
5728 into the function silc_client_notify_by_server.
5730 * Added new function silc_idlist_replace_channel_id into the files
5731 silcd/idlist.[ch] to replace the Channel ID.
5733 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Call silc_server_command_identify_check always when processing
5736 the IDENTIFY command in silcd/command.c
5738 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5741 send keepalive packets. The packet can be sent by clients,
5742 servers and routers.
5744 Added function silc_socket_set_heartbeat into the file
5745 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5746 If not set, the heartbeat is not performed. The actual
5747 heartbeat is implemented in the low level socket connection
5748 library. However, application is responsible of actually
5751 Added silc_server_send_heartbeat to send the actual heartbeat
5752 packet into silcd/packet_send.[ch]. Server now performs
5753 keepalive with all connections.
5755 * Added silc_task_get_first function into lib/silcutil/silctask.c
5756 to return the timeout task with shortest timeout. There was a bug
5757 in task unregistration that caused problems. TODO has been
5758 updated to include that task system must be rewritten.
5760 * The client library will now resolve the client information when
5761 receiving JOIN notify from server for client that we know but
5762 have incomplete information.
5764 * Rewrote parts of silc_server_remove_from_channels and
5765 silc_server_remove_from_one_channel as they did not remove the
5766 channel in some circumstances even though they should've.
5768 * Encryption problem encountered in server:
5770 The LEAVE command used to send the Channel Key packet to the
5771 router immediately after generating it. However, the code
5772 had earlier sent Remove Channel user packet but not immediately,
5773 ie. it was put to queue. The order of packets in the router
5774 was that Channel Key packet was first and Remove Channel User
5775 packet was second, even though they were encrypted in the
5776 reverse order. For this reason, MAC check failed. Now, this
5777 is fixed by not sending the Channel Key packet immediately but
5778 putting it to queue. However, this is more fundamental problem:
5779 packets that are in queue should actually not be encrypted
5780 because packets that are sent immediately gets encrypted
5781 actually with wrong IV (and thus MAC check fails). So, packets
5782 that are in queue should be encrypted when they are sent to
5783 the wire and not when they put to the queue.
5785 However, the problem is that the current system has not been
5786 designed to work that way. Instead, the packet is encrypted
5787 as soon as possible and left to the queue. The queue is then
5788 just purged into wire. There won't be any fixes for this
5789 any time soon. So, the current semantic for packet sending
5792 o If you send packet to remote host and do not force the send
5793 (the packet will be in queue) then all subsequent packets to the
5794 same remote host must also be put to the queue. Only after the
5795 queue has been purged is it safe again to force the packet
5798 o If you send all packets immediately then it safe to send
5799 any of subsequent packets through the queue, however, after
5800 the first packet is put to queue then any subsequent packets
5801 must also be put to the queue.
5803 Follow these rules and everything works fine.
5805 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Added new function silc_server_remove_clients_by_server to
5808 remove all client entries from ID list when the server connection
5809 is lost. In this case it is also important to invalidate all
5810 client entires as they hold the invalid server entry. This
5811 fixes fatal bug when server has lost connection and will reconnect
5814 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Made some sanity checks to silc_server_daemonise like to check
5817 whether the requested user and group actually exists.
5819 * Added sanity check to SKE's silc_ske_responder_finish to check
5820 that the public and private key actually is valid.
5822 * Invalidate the client's nickname when receiving Replace ID
5823 packet and the Client ID is being replaced. This means that the
5824 server will query the nickname if someone needs it (client)
5827 * Sort the ID Cache in client library when the ID Cache data
5828 has changed (needs sorting).
5830 * Do not allow for SILC client to create several connections to
5831 several servers. The client does not support windows right now
5832 and generating multiple connections causes weird behaviour.
5834 Irssi-silc client does support windows and can handle several
5835 connections without problems, see: www.irssi.org and SILC plugin.
5837 * Fixed some places where client was added to the IDList. The
5838 rule of thumb is following (in order to get everything right):
5839 If the client is directly connected local client then the
5840 `connection' argument must be set and `router' argument must be
5841 NULL to silc_idlist_add_client function. If the client is not
5842 directly connected client then the `router' argument must
5843 bet set and the `connection' argument must be NULL to the
5844 silc_idlist_add_client function.
5846 * The funtion silc_server_packet_send_local_channel actually did
5847 not check whether the client was locally connected or not. It
5848 does that now. Fixed a bug related to LEAVE command.
5850 * Fixed Remove Channel User payload parsing bug in server's
5851 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5853 * The server's silc_server_save_channel_key now checks also the
5854 global ID list for the channel as it might not be in the local
5855 list. Fixed a bug related to LEAVE command.
5857 * Is this the end of the [<unknown>] buglet that has been lurking
5858 around for a long time? A little for loop fix in server's
5859 silc_server_command_whois_parse that is used by both IDENTIFY
5860 and WHOIS command. At least, this was a clear bug and a cause
5861 of one type of [<unknown>] buglet.
5863 * WHOIS and IDENTIFY commands call the function
5864 silc_server_command_[whois/identify]_check function even if
5865 we are not router server.
5867 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Added --with-gmp configuration option. If set the GMP
5870 is always compiled in the SILC source tree. If not set then
5871 it is checked whether the system has the GMP3 installed. If
5872 it has then the GMP won't be compiled (the system's headers
5873 and library is used), if it doesn't have it then the GMP is
5874 compiled in the SILC source tree.
5876 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Changed RSA private exponent generation to what PKCS #1
5879 suggests. We try to find the smallest possible d by doing
5880 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5881 not security fix but optimization.
5883 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Added new config entry [Identity] to fork the server and run
5886 it as specific user and group. A patch from Bostik.
5888 * Imported Dotconf configuration library into lib/dotconf.
5889 This will be used to create the SILC configuration files later.
5890 It will appear in the distsribution after this commit.
5892 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * A big code auditing weekend happening. Auditing code for
5895 obvious mistakes, bugs and errors. Also, removing any code
5898 Removed files for being obsolete:
5900 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5901 inline in the file lib/silcutil/silcbuffer.h)
5903 o lib/silcutil/silcbufutil.c (the header has inline versions)
5905 Changed code to fix possible error conditions:
5907 o The buffer formatting routines now check that the destination
5908 buffer really has enough space to add the data. This applies for
5909 both buffer formatting and unformatting
5910 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5911 unformatting was changed to accomodate following rules:
5912 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5913 sent to the function while XXX_*STRING will not allocate or copy
5914 the data into the buffer. Instead it sets the pointer from the
5915 buffer into the pointer sent as argument (XXX_*STRING used to
5916 require that the pointer must be allocated already). This change
5917 makes this whole thing a bit more consistent and more optimized
5918 (note that the data returned in the unformatting with XXX_*STRING
5919 must not be freed now). The routines return now -1 on error.
5921 o Tried to find all code that use buffer_format and buffer_unformat
5922 and added return value checking to prevent formatting and
5923 especially unformatting errors and possible subsequent fatal
5926 o Changed ske->x and ske->KEY to mallocated pointers in
5927 lib/silcske/silcske.h. Fixed possible data and memory leak.
5929 o Added return value checking to all *_parse* functions. Fixed
5930 many memory leaks as well.
5932 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5933 so that buffer overflows would not happen. All code now also
5934 checks the return value as it can fail.
5936 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Added reconnection support to server if the normal server looses
5939 its connection to the router (for example if router is rebooted).
5940 The server performs normal reconnection strategy implemented
5941 to the server. Affected file silcd/server.c.
5943 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added new packet type SILC_PACKET_SET_MODE that is used to
5946 distribute the information about changed modes (for clients,
5947 channels and clients channel modes) to all routers in the
5948 network. Updated the protocol specification accordingly.
5950 Added functions into silcd/packet_send.c and
5951 silcd/packet_receive.c: silc_server_send_set_mode,
5952 silc_server_set_mode.
5954 Added new files silcmode.[ch] into lib/silccore that implements
5955 the encoding and decoding of Set Mode Payload. Added new type
5956 SilcSetModePayload. Moved the definitions of different modes
5957 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5959 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Oops, a little mistake in server's connection authentication
5962 protocol. The protocol is not ended with FAILURE but with
5963 SUCCESS if the authentication is Ok. :) Affected file is
5966 * Implemented NICK_CHANGE notify handling in server in the file
5967 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5968 the local clients on the channel. After the changing nickname
5969 in router environment snhould work and the [<unknown>] nickname
5970 should appear no more.
5972 The silc_server_replace_id function that receives the Replace ID
5973 payload now sends the NICK_CHANGE notify type also in the file
5974 silcd/packet_receive.c
5976 * Changed WHOIS and IDENTIFY command to support the maximum amount
5977 of arguments defined in protocol specs (3328 arguments). This
5978 fixed a bug that caused problems when there were more than three
5981 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added extra parameter, command identifier, to the
5984 silc_client_send_command so that explicit command identifier
5987 Changed that ID list routines uses specific command identifier
5988 when sending WHOIS/IDENTIFY requests to the server so that they
5989 can be identified when the reply comes back.
5991 Affected files lib/silcclient/command.[ch],
5992 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5994 * Added `sender' argument to silc_server_packet_send_to_channel
5995 to indicaet the sender who originally sent the packet to us
5996 that we are now re-sending. Ignored if NULL. Affected file
5997 silcd/packet_send.[ch].
5999 * Added some server statistics support in silcd/server_internal.h
6000 SilcServerStatistics structure and around the server code. Also
6001 send some nice statistics information when client is connecting
6004 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Fixed channel ID decoding in server's JOIN command reply in
6007 silcd/command_reply.c
6009 * Fixed braodcasting of replace ID payload to not to send it if
6010 we are standalone server in silcd/packet_receive.c.
6012 * Fixed all channel message sending routines to not to send
6013 packets to clients that has router set, since they are routed
6014 separately in the same function earlier. Affects file
6015 silcd/packet_send.c and all channel packet sending functions.
6017 * In USERS reply, res_argv[i] are not allocated, the table
6018 is allocated. Thus changed that free the table, not its
6021 * In server's whois_check and identify_check if the client is
6022 locally connected do not send any WHOIS commands - they are not
6025 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Fixed some minor bugs in client when sending WHOIS command. The
6028 arguments was in wrong order.
6030 * Removed statis function add_to_channel from server in
6031 silcd/command.c that was previously used with the joining but
6034 * Tested USERS command in router environment successfully with two
6035 routers, two servers and two clients.
6037 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Reorganized the USERS command and command reply in client library
6040 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6041 When the command is given by user we register a pending command
6042 callback that will reprocess the command after the reply has been
6043 received from the server. When reprocessing the packet we then
6044 display the information. Thus, the USERS information is displayed
6045 now in the command callback instead of in the command reply
6046 callback. The processing of the command is same as previously
6047 when server has sent the command reply in the JOINing process.
6049 * Added to USERS command in silcd/command_reply.c to join the client,
6050 we didn't use to know about, to the channel after we've created
6051 a client entry for it. Also, for clienet we did know already still
6052 check whether it is on the channel or not and add it if not.
6054 * Removed silc_server_command_join_notify as the function and its
6057 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Changed the client's pending command handling to the same as the
6060 server's pending command handling. It is also now possible to
6061 execute command reply functions from other command reply
6062 function as the function callbacks for commands and command
6063 replies are one and same. The pending commands are not static
6064 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6065 in client connection context. Thus, pending commands are server
6066 connection specific as it is convenient.
6068 Changed the function silc_client_command_pending and
6069 silc_client_command_pending_del and added new function
6070 silc_client_command_pending_check. Removed the
6071 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6074 * Added cmd_ident, current command identifier, to the client
6075 connection context in lib/silcclient/client.h to keep track on
6076 command identifiers used in command sending. Client's command reply
6077 function handling now supports the mandatory command identifiers.
6079 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6080 funtions in client to fully support pending command callbacks.
6082 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6083 as one of the arguments to the application in the command reply
6086 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6087 before first releasing SILC but came back. Now it is removed again
6088 and should come back nomore. The FORWARDED flag was used only
6089 by the JOINing procedure by forwarding the command packet to router.
6090 Now, the JOINing procedure has been changed to more generic (due
6091 to various router environment issues) and FORWARDED is not needed
6092 anymore for anything. The protocol specification is yet to be
6095 Now, removed silc_server_packet_forward from server and the flag
6096 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6098 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Renamed NAMES command to USERS command. The NAMES was named that
6101 due to historical reasons. Now it is renamed. Also, rewrote
6102 parts of the USERS command. The nickname list is not sent anymore
6103 by the server. Only Client ID and mode lists are sent in the USERS
6104 command. Changed this also to the protocol specification.
6106 The client now resolves the names and stuff after it receives
6107 the USERS list from the server when joining to the channel.
6109 * WHOIS and IDENTIFY commands has been changed to support multiple
6110 Client ID's per command. One can now search for multiple users
6111 in the network by sending only one WHOIS or IDENTIFY command.
6112 Changed the code and the protocol specifications.
6114 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6115 uses silc_server_command_whois_parse to parse the request. */
6117 * If normal server, do not parse the WHOIS and IDENTIFY requests
6118 before sending it to the router. Saves some time.
6120 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Fixed JOIN command on client library. Wrong number of arguments
6123 used to crash the client.
6125 * Added silc_server_channel_has_global function to check whether
6126 channel has global users or not.
6128 * Added silc_server_channel_has_local function to check whether channel
6129 has locally connected clients on the channel.
6131 * The silc_server_remove_from_one_channel now checks whether the
6132 channel has global users or not after given client was removed from
6133 the channel. It also checks whether the channel has local clients
6134 on the channel anymore. If it does not have then the channel entry
6135 is removed as it is not needed anymore.
6137 * The silc_server_notify now checks on JOIN notify whether the joining
6138 client is one of locally connected or global. If it is global then
6139 the channel has now global users on the channel and that is marked
6140 to the channel entry. Also, it now saves the global client to
6141 global list who is joining and JOINs it to the channel. This is
6142 for normal server, that is.
6144 Changed silc_server_send_notify_on_channel,
6145 silc_server_packet_relay_to_channel and
6146 silc_server_packet_send_to_channel check if we are normal server
6147 and client has router set (ie. global client) do not send the
6148 message to that client, as it is already routed to our router.
6150 * Implemented LEAVE notify type handling in silc_server_notify
6153 * Tested LEAVE command in router environment successfully. Tested
6154 with two routers, two servers and two clients.
6158 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6160 * Implemented SIGNOFF notify type handling in silc_server_notify
6163 * silc_server_remove_id now removes the client entry from all channels
6164 it has joined and thusly sends SIGNOFF notify type.
6166 * Rewrote the NAMES list generation in server by removing two excess
6167 loops. The lists are created now inside one loop.
6169 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * silc_server_remove_channel_user checks now also global list
6172 for channel and client.
6174 * silc_server_new_channel_user checks now both local and global
6175 list for channel and client. Fixed a bug in client id decoding.
6176 Used to decode wrong buffer.
6178 * silc_server_channel_message checks now both local and global
6179 list for channel entry.
6181 * Tested channel joining (hence JOIN) in router environment
6182 successfully. Tested with two routers, two servers and two
6185 * Tested channel message sending in router environment successfully.
6187 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Added silc_server_save_channel_key into server.[ch] to save the
6190 received channel key in Channel Key payload processing. It is
6191 also used in JOIN command reply handling.
6193 Equivalent function silc_client_save_channel_key added into
6194 client.[ch] into client library.
6196 * Changed JOIN command reply to send information whether the channel
6197 was created or not (is existing already) and the channel key
6198 payload. Changed protocol specs accordingly.
6200 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6201 the request was sent by ID and not by nickname. Crashed on
6204 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6207 now correctly save the received data.
6209 * silc_server_free_sock_user_data now notifies routers in the
6210 network about entities leaving the network.
6212 At the same time implemented functions silc_server_remove_id
6213 and silc_server_send_remove_id to receive and send REMOVE_ID
6214 packets. The packet is used to notify routers in the network
6215 about leaving entities. The ID removed will become invalid in
6218 * Added function silc_idlist_del_server into server. Removes and
6219 free's server entry from ID list.
6221 * silc_server_private_message function now checks, if we are router,
6222 that the destination ID really is valid ID, naturally.
6224 * In router when NEW_ID packet is received (for new client) the
6225 hash of the Client ID is saved in the ID Cache but the
6226 client->nickname is set to NULL, instead of putting the hash
6229 IDENTIFY command now also checks that client->nickname must be
6230 valid. If it is not if will request the data from the server who
6231 owns the client. Added new function
6232 silc_server_command_identify_check.
6234 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6235 to set the command to already allocated Command Payload.
6237 * Tested private message sending in router environment with two
6238 routers, two servers and two clients. Fixed minor bugs and now
6241 * Fixed segfault from client's NAMES command. Used to crash if
6244 * Forwarded packets must not be routed even if it is not destined
6245 to the receiver. Changed server code comply with this.
6247 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Added `require_reverse_mapping' boolean value to ServerParams
6250 structure. If TRUE (not default) the server will require that
6251 the connecting host has fully qualified domain name.
6253 If the reverse mapping is not required and hostname could not be
6254 found the IP address is used as hostname.
6256 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Implemented version string checking to both client and server.
6259 The check is incomplete currently due to the abnormal version
6260 strings used in development version of SILC.
6262 * Changed all command functions in server to use the new
6265 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Changed char *data to unsigned char *data in ID Cache system to
6268 support binary data as ID Cache data. Changed code to support
6269 binary data in lib/silccore/idcache.c.
6271 * Renamed silc_server_packet_relay_command_reply to
6272 silc_server_command_reply as it is normal packet receiving
6273 function. Rewrote the function to accept command replys for
6274 servers and not only for clients.
6276 * Mark remote router always as registered server if we are connecting
6277 to it. Otherwise, commands sent by the router to us are ignored.
6279 * All ID List find routines now returns the ID Cache Entry pointer
6280 as well if requested.
6282 * WHOIS command works now in router environment, tested with two
6283 routers, two servers and two clients.
6285 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6286 in router environment (as it is almost equivalent to WHOIS) but
6287 hasn't been tested thoroughly. Added new functions:
6289 silc_server_command_identify_parse
6290 silc_server_command_identify_send_reply
6291 silc_server_command_identify_from_client
6292 silc_server_command_identify_from_server
6294 * Disabled route cache adding because adding two different ID's with
6295 same IP replaces the old cache entry thus giving wrong route.
6296 The entry->router->connection is always the fastest route anyway
6297 so route cache may not be needed. Of course, new routes maybe
6298 established after receiving the ID when the entry->router->connection
6299 might not be anymore the most optimal.
6301 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Add route cache for received ID for fast routing.
6305 * Added silc_server_packet_route to route received packet on router
6306 that is not destined to us.
6308 * Renamed silc_server_get_route to silc_server_route_get.
6310 * Added id_string and id_string_len fields into SilcServer to
6311 include encoded ServerID for fast comparing without excess
6312 encoding of the ID's.
6314 * Cleaned up WHOIS command on server side. Added following static
6317 silc_server_command_whois_parse
6318 silc_server_command_whois_check
6319 silc_server_command_whois_send_reply
6320 silc_server_command_whois_from_client
6321 silc_server_command_whois_from_server
6323 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6324 arguments in command replies. All command functions should be
6325 updated to use this macro.
6327 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Minor typo fixes on command reply handling on server.
6331 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Added silc_server_command_add_to_channel internal routine to add
6334 the client to the channel after router has created the channel and
6335 sent command reply to the server.
6337 * Added generic silc_server_send_command to send any command from
6340 * Use static buffer with ID rendering instead of duplicating data.
6342 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Fixed a channel user mode bug when joining to a channel server gave
6345 everybody channel founder rights, oops.
6347 * We mark ourselves as the router of the incoming server connection
6348 if we are router ourselves. This way we can check in some packet
6349 sending functions whether it is locally connected server. For
6350 incoming router connections we put NULL.
6352 * For router sending packets locally means now always sending the
6353 packet cell wide; to local clients and local servers. For normal
6354 server sending packet locally means sending it to only local
6357 * Fixed the JOIN command to really work in router environment. If the
6358 channel is created it is always created by the router. Router is
6359 also responsible of making the initial joining to the channel,
6360 sending JOIN notify to the sending server and distributing
6361 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6362 does not exist server doesn't do anything else but forward the
6363 command to the router which performs everything.
6365 * Added silc_server_send_channel_key function to send the Channel Key
6368 * Added silc_server_create_channel_key to create new channel key. The
6369 channel key is now re-generated everytime someone joins or leaves
6370 a channel, as protocol dictates. Note: channel->key_len is the
6373 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6376 packet_receive.[ch] to separate packet sending and receiving
6377 routines. The server.[ch] now includes everything else including
6378 actual packet processing (writing and reading data) and other
6381 Renamed silc_server_private_message_send_internal to
6382 silc_server_send_private_message. The routine is still though
6383 used only to relay private messages as server does not send
6384 private messages itself.
6386 Renamed silc_server_new_channel to silc_server_create_new_channel
6387 and added new function sicl_server_new_channel that handles the
6388 incoming New Channel packet. Added also new sending function
6389 silc_server_send_new_channel to send New Channel Payload.
6391 * Added new function silc_server_notify to process incoming notify
6392 packet to the server/router. Server may then relay the notify
6393 to clients if needed.
6395 * Added new function silc_server_new_channel_user to process incoming
6396 New Channel User packet. Router will redistribute the packet and
6397 send JOIN notify to its local clients and locally connected servers
6398 if needed. Normal server will send JOIN notify to its local client
6399 on same channel when received this packet. Added also corresponding
6400 sending function silc_server_send_new_channel_user to sent the
6403 * Added boolean route argument to send_notif_to_channel and
6404 packet_send_to_channel functions to attempt to route the packet
6405 if it is TRUE and send only locally if it is FALSE.
6407 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * silc_server_replace_id now broadcasts the received replace ID
6410 packet if it is not broadcast packet already. The router must
6411 broadcast to inform other routers about changed ID.
6413 * Added backpointer to server's router into SilcServer context in
6414 silcd/server_internal.h.
6416 * Fixed silc_server_packet_broadcast to send correct broadcast
6419 * The channel key is now distributed to the local client as soon
6420 as it is received from the router (in router environment) so that
6421 no other packet may be sent for the channel until client has
6424 * silc_server_remove_channel_user now broadcasts the received
6425 Remove Channel User packet if it is not broadcast packet already.
6426 The router must broadcast to inform other routers about removed
6429 * Added users field into SilcPacketContext that is a reference count
6430 of the context. One can increase the reference count by calling
6431 silc_packet_context_dup which is now changed to just increase the
6432 reference count instead of duplicating the data. The reference
6433 count is decresed by calling silc_packet_context_free that will
6434 free the data after the reference count hits zero.
6436 For now on the packet context and everything allocated into it
6437 (including the raw packet from network) must be freed by calling
6438 the new silc_packet_context_free function. Added also new function
6439 silc_packet_context_alloc that must be used now to allocate the
6440 context. This also means that if a routine is asynchronous from
6441 silc_[client/server]_packet_parse_type the packet context must
6442 be duplicated by calling silc_packet_context_dup. Otherwise it
6443 gets free'd after silc_[client/server]_packet_parse_type returns.
6444 Also, one must remember that if packet is duplicated then its
6445 reference count must be decresed by calling the free function as
6446 many times as it was duplicated.
6448 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6449 from both client and server.
6451 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Made joining to a channel working in router environment.
6455 * Cleaned up JOIN command on server side and create function
6456 silc_server_command_join_channel internal routine to make the
6459 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Changed silc_command_pending list to SilcDList. Also, added
6462 `ident' field to SilcServerCommandPending structure to identify
6463 the reply and to call correct callback.
6465 Added silc_server_command_pending_check function to replace the
6466 corresnponding macro. The silc_command_pending list is not
6469 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6470 to set identifier to previously allocated Command Payload. It
6471 is used to set identifier for command when resending Command
6474 * Added silc_command_payload_encode_payload to encode Command
6475 Payload buffer from SilcCommandPayload structure.
6477 * Added silc_argument_payload_encode_payload to encode Argument
6478 payload buffer from SilcArgumentPayload structure.
6480 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Changed WHOIS command to support router connection on server side.
6483 The whois request is always sent to router unless the server is
6484 standalone server. After server has received the reply from the
6485 router will it send the reply to the client.
6487 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6488 broadcast received broadcast packet. The function is used only
6489 by router. The broadcast packet is always sent to the router's
6492 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6493 render given ID to printable string, for log files for example.
6495 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Made basic router to router connections working. At least they
6498 can now connect to each other but nothing really works the way
6499 they are supposed - yet.
6501 * Added new initiator token to RouterConnection configuration
6502 file in silcd/serverconfig.[ch]. It is used to tell whether we
6503 are the initiator to the remote router or whether we'll expect
6504 the other end to connect.
6506 * Moved registering of listener task to silc_server_init, hence
6507 the server starts listenning as soon as it is run, even if it
6508 does not have connections to other routers. Let's see how well
6511 * Changed default connection retry timeouts for more suitable in
6514 * Removed cipher and such arguments from silc_idlist_add_client
6515 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6516 Added new function silc_idlist_add_data to add the keys and stuff
6519 * Added SilcIDListData structure and added it to SilcClientEntry
6520 and SilcServerEntry as their first field in the structure. This
6521 way we can explicitly cast the ID entries to the SilcIDListData
6522 structure and get common data for the entries. In past, we had
6523 to first check what type of connection it is and then cast it to
6524 correct ID entry type. Now, we can directly cast the opaque
6525 pointer to the SilcIDListData (no matter what ID entry it actually
6526 is) and get the data needed.
6528 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6531 in some circumstances even if threre were timeout tasks, though not
6532 IO tasks, but tasks anyway. Now fixed.
6534 * Defined SilcServerConnection structure to hold connection specific
6535 stuff about directly connected servers and routers. The definition
6536 is currently in silcd/server_internal.h. I thought about having
6537 a bit more important role fro this struct but for now it is used
6538 only when connecting to other server (or router actually).
6540 * Added connecting retry support in server when connecting to
6541 router(s). The retry feature implement exponential backoff
6542 algorithm. Also, added SilcServerParams structure to hold default
6543 parameters for server. For now, it include these retry settings
6544 and are hard coded. After server is moded to be as Silc Server
6545 Library this structure will be more important.
6547 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Changed client librarys channel->clients table to SilcList and
6550 changed code accordingly.
6552 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Changed client's channel table to SilcList and changed code
6555 accordingly. Also changed SilcChannelClientEntry to include back-
6556 pointer to the channel so that client entry can use that structure
6557 as list as well and we have fast cross-reference to the channel.
6558 This change dramatically decreased the complexity of channel
6559 handling with client entry and vice versa (removed one extra
6560 loop when searching for channel entry from many functions).
6562 * Changed server->sim from table to SilcDList and changed code
6565 * NAMES command can now be used from user interface. It will show
6566 the user list on the channel, neatly.
6568 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6569 Code now saves realname of the user if it becomes available.
6571 * Renamed configure.in to configure.in.pre and made ./prepare
6572 script to automatically add correct version string to
6573 configure.in which it creates from configure.in.pre.
6575 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * NAMES command reply now shows users mode with the nickname when
6580 * Moved silc_client_ch[u]mode[_char] functions from
6581 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6582 place sucks, they are utility functions and should be in some
6585 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6587 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6590 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Added TRQ (efficient deque and list library) into lib/trq. This is
6595 a very good list library that is currently used in the SILC. Defined
6596 SilcList API over the library because I didn't like the API very
6597 much. See lib/trq/silclist.h for the API and examples of how to
6598 use the API. Fixed various places in the code to use the new
6599 SilcList API. The SilcList is meant for lists that has a structure
6600 already defined as a list. It is not suitable to add just some
6601 context to the list (in TRQ, the context is the list actually).
6603 So, I defined SilcDList that can be used for the purpose where
6604 predefined list structure does not exit. This can be used as
6605 such list. Now some context just can be added to the SilcDList.
6606 Currently this list is not used in the SILC just yet, though there
6607 are a lot places where this can replace dynamically allocated
6608 tables and I will fix these places, later, to use SilcDList.
6609 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6610 and use TRQ internally).
6612 Also fixed some annoying warning messages that the original TRQ
6613 code generated. Also minor changes to TRQ's Makefile.in.
6615 * Added support for querying by Client ID to both WHOIS and
6616 IDENTIFY commands into server, as required by the protocol.
6618 * Removed method function pointers from SilcBuffer structure. They
6619 weren't used to anything and just increased the context size for
6620 no good reason. This change also made silc_buffer_alloc and
6621 silc_buffer_free functions inline functions.
6623 * Disabled command flooding detection support until it's fixed so
6624 that it accepts commands in but does not execute them more than once
6627 * Added silc_net_localhost(), to return local hostname, into
6628 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6629 that must be initialized before calling silc_client_init.
6631 * Added new function: silc_server_send_notify_on_channels to send
6632 notify messages to all channels client has joined. It is assured
6633 that the message is sent only once per client.
6635 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6636 lib/silcutil/silcutil.[ch] as silc_format function. The new
6637 function is generic and is used by server as well, not only by
6638 the logging routines.
6640 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6641 the provided version string was not acceptable. Added new function:
6642 silc_ske_check_version into lib/silcske/silcske.h. The function
6643 must be implemented by the application (client or server) and it
6644 does not reside in the SKE library. The function checks the version
6645 string remote end sent.
6647 * Added back pointers (to opaque context and to SilcSocketConnection)
6648 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6650 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6651 duplicate packet context structure.
6653 * Changed `notify' client operation to send same arguments as client
6654 receives from server except for ID's. ID's are mapped to correct
6655 ID entry and that is returned. Also, if channel entry is not sent
6656 by server but the notify is for channel the channel entry is sent
6657 to application (otherwise application doesn't know that it is for
6658 channel (library gets it from packet's Destination ID)).
6660 * Added silc_client_remove_from_channels into client library to
6661 remove a client from all channels it has joined to. Used when
6662 received SIGNOFF notify from server. Added also new function
6663 silc_client_replace_from_channels to replace old ID entry with
6664 new ID entry on all channels. Used when received NICK_CHANGE
6667 * Fixed ID Cache list handling in silc_idlist_get_client in
6668 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6669 to get (or query) client by ID.
6671 * Updated TODO list.
6673 * Added connection authentication status message defined by the
6674 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6675 support for these into the code in client and server side.
6677 * Added generic function silc_client_send_command to send any command
6678 with variable argument list. Application should use this function
6679 to send commands if the command functions provided by the library
6680 does not suite for the application's user interface needs.
6682 * Added new `failure' client operation. Application is notified about
6683 received failure packet if client is executing a protocol. In this
6684 case the protocol's execution has failed.
6686 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6687 is required by the protocol.
6689 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6690 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6693 * Added status flag to SilcSKE object to indicate realtime status
6694 of the SKE protocol.
6696 * Application receives now exactly same command reply arguments as
6697 the library receives from server. However, if ID is received the
6698 corresponding ID entry is returned to the application (eg. Client
6699 ID is mapped to correct SilcClientEntry entry and that is returned).
6700 Changed command_reply client operation due to this change.
6702 * Changed all ID's in commands and in command replys as ID Payloads.
6703 Change affected both client and server side codes.
6705 All ID's sent in SILC network (with execption of ID's in SILC
6706 Packet header) are sent in ID Payload to support variable length
6709 * Server now notifies nick changes and notifies all clients on
6710 the channels about the new nickname (about the new Client ID,
6713 * Implemented CMODE command to change channel modes. Supports all
6714 channel modes defined by the protocol specs except ban and invite
6715 lists. (Also, private channel key mode is supported but support for
6716 setting private channel key in client is missing, thus, this mode
6717 has no effect on client side (except that server requires that the
6718 client uses private channel key and normal channel traffic does not
6721 Also, invite mode works per se, but INVITE command does not work
6722 yet correctly, so you can set channel as invite only channel but
6723 inviting clients to the channel does not work (it is yet to be
6724 thought what's the best way to do it).
6726 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6727 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6728 Implemented CUMODE command to change user's mode on the channel.
6729 Supports all modes defined by the protocol specs.
6731 * Added NAMES command reply to return users modes on the channel.
6733 * Removed unnecessary and slow ciphers from lib/silccrypt.
6735 * Set SO_KEEPALIVE option to connection sockets by default.
6737 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6739 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6740 redefined the Notify Payload into protocol specs.
6742 * Added silc_id_payload_parse_id to get ID directly from raw
6745 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6748 accept searching by Client ID as well.
6750 * Added support for LEAVE and SIGNOFF notify types in client library.
6752 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6753 to parse ID Payload from raw data.
6755 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Added flags parameter into silc_ske_assemble_security_properties
6758 function in lib/silcske/silcske.[ch].
6760 * Changed notify client operation to fit better for notify messages
6761 sent by server. The notify payload received from server is now
6762 passed to the application (after parsing it to SilcNotifyPayload).
6763 It is application's responsibility to retrieve the arguments
6764 from the payload and show the message the way it wants. The message
6765 sent by server is implementation specific.
6767 * Changed public keys to comply with the protocol specification.
6768 Old public keys are not supported anymore and are not compatible.
6770 * Removed nickname from Channel Payload as the latest draft removed
6771 it. The client must resolve the nickname from the NAMES command
6772 reply received when it joined the channel.
6774 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6776 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Fixed some errors in protocol specification drafts.
6780 * Created lib/silccore/silcnotify.c to implement Notify Payload
6781 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6782 generic payloads described by protocol specifications. The file
6783 includes implementations for ID Payload and Argument Payload.
6785 * Changed Command Payload implementation to use the new Argument
6786 Payload. Changed command_xxxx_payload to command_payload_xxxx
6787 to comply with SILC coding conventions.
6789 * Added suppport for Argument Payload handling in Notify Payload
6790 implementation as protocol requires it. Added the new support
6791 into server and client lib as well.
6793 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Added support for multiple nicknames on same channel. [n] is
6796 added locally to the nickname if there are more than one same
6797 nicknames on the channel.
6799 * Server now sends all nicknames that matched WHOIS request.
6800 Client also shows the list received from server.
6802 * Added TOPIC command to client side. User can now set and show
6803 current topic on channel.
6805 * Added MOTD command to client and server. Also, server sends the
6806 motd when client connects to the server.
6808 * Changed version strings to comply ISO 8601.
6810 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Fixed protocol error handling in client library. It should now
6813 cope even if the SKE fails for some reason.
6815 * Made new protocol specification drafts for submitting to IETF.
6817 * Implemented TOPIC command to server in silcd/command.c.
6819 * Added two new notify types into lib/silccore/silcnotify.h:
6820 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6821 notify nickname change and topic setting/change on a channel.
6823 * API change of command_reply operation in client library. The
6824 application gets now the status type received from server as well.
6826 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6830 * Cras fixed and optimized the packet handling even further and
6831 it should work now. Minor change to the prototype of function
6832 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6834 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Added new function into lib/silcutil/silcschedule.[ch]:
6837 silc_schedule_with_fd to select() a specified fd. The function
6838 returns after timeout expires or data arrives or goes. The
6839 function is used by packet routines to wait that all data is
6840 received from network.
6842 * Fixed data reading from network in lib/silccore/silcpacket.c.
6843 The code now assures that all data is read from the fd and then
6844 continues packet processing. This was a bug fix since the code
6845 used to drop some data in some circumstances.
6847 * Added new function into lib/silcclient/client.[ch]:
6848 silc_client_start_key_exchange to start key exchange after
6849 connection has been established to server. The code internally
6850 now uses this funtion but its main purpose was to provide it
6851 for applications that perform their own connecting. After
6852 application has created a connection it merely calls this
6853 function to start the key exchange between client and server.
6854 The library takes care of everything else after that.
6856 Updated also lib/silcclient/README to explain the usage of
6859 * Do not send to application information that connection has
6860 been established. Application gets notified it by connect
6863 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Applied cras's patch to add silc_schedule_one function. The
6866 function runs scheduler once and returns.
6868 * Fixed the scheduler after cras messed it up. The timeout
6869 handling works now as it's supposed to work.
6871 * Added into lib/silccore/ silcnotify.h to include notify
6872 message types support. Changed silc_server_send_notify*
6873 functions, in server.[ch], to support those new notify types.
6874 Added the support for the notify types into client library,
6875 as well. Added new notify client operation into ops.h in
6878 * Changed silc_server_packet_send_to_channel to send normal
6879 packets instead of just channel message packets. The function
6880 is now used to send the notify packets to channels. It is not
6881 used to send channel message packets anymore, as server never
6884 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6885 va_arg()s as it seems to require it nowadays. I guess, if SILC
6886 is compiled with older va_arg() the new code should work anyway.
6888 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Splitted core library. Core library (lib/silccore) includes
6891 now only SILC protocol specific core (and common) components.
6892 Created new utility library (lib/silcutil) that includes more
6893 generic purpose stuff. The stuff for util library was taken
6894 from the old core library. This was minor and easy split.
6896 * Created SILC Client Library (lib/silcclient) that includes
6897 implementation of the SILC client without user interface. This
6898 was major move from silc/ directory. The code has been changed
6899 so that it is transparent towards the user interface. The
6900 silc/ directory includes now the same user interface as before
6901 and it uses the new client library. Read lib/silcclient/README.
6902 Basicly, the client library performs everything else related
6903 to SILC except user interface handling. Also, configuration
6904 files are considered to be part of user interface and library
6905 does not handle them.
6907 This change also changed a lot of structures, function naming etc.
6908 Most important change was that SilcClientWindow object was
6909 renamed to SilcClientConnection in the client library. Created
6910 also new file lib/silcclient/ops.h. Also added new files
6911 silc/local_command.[ch] and silc/client_ops.[ch].
6913 All these changes were made to make it easier for user interface
6914 designers to create what ever user interface for the SILC client
6917 It is also expected that the server will be moved to lib
6918 directory as well and SILC Server Library will be created;
6919 sometimes in the future.
6921 * Removed Local commands from lib/silccore/silccommand.h as
6922 they are application specific and new client library does not
6923 handle any of those anymore.
6925 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6926 old client implementation in silc/.
6928 * Added support for callback functions in SILC_LOG_* macros.
6929 Application can now set its own callbacks that will be called
6930 instead of using the default functions that will always print
6931 the debug messages to stderr (or stdout). Also, debugging can
6932 now be disabled by setting silc_debug to FALSE and re-enabled by
6933 setting it to TRUE. Note, that logging will still work even
6934 if debugging is disabled.
6936 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6937 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6938 silc_log_reset_debug_callbacks.
6940 * To enable debugging in silc client one must give now -d
6941 option on command line.
6943 * Changed silc_schedule_init to automatically allocate task queues
6944 if they are not allocated before calling it.
6946 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Added GMP 3.1 into math library.
6950 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6953 a channel in SILC network. The packet is used by servers and
6954 routers to notify other routers that user has left a channel.
6955 This little feature was missing until now. Added the feature
6956 to protocol specification as well.
6958 Added functions: silc_server_send_remove_channel_user and
6959 silc_server_remove_channel_user into server.[ch].
6961 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6962 lib/silccore/silcpacket.h. However, they are not implemented
6965 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Fixed joining to a channel and sending channel messages
6968 between server and router. The channel message sending should
6969 now work inside a cell.
6971 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Fixed the private message sending between server and router.
6974 The private message sending should now work inside a cell.
6976 * Added silc_server_replace_id into server.[ch] to replace
6977 existing ID in the SILC network.
6979 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6980 and silc_idlist_replace_server_id into idlist.[ch] in server.
6982 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Fixed the server to server connections. Server can again now
6985 connect to router. Router to router connections probably does
6988 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Added dynamic protocol registering support. Now protocols can
6991 registered and unregistered on the fly. Patch by cras.
6993 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Added lib/contrib directory to hold routines that some platforms
6996 don't have but are needed by SILC.
6998 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6999 into lin/contrib to provide getopt() and getopt_long() for
7000 those who don't have it.
7002 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7004 * Added AWAY command to client. When away message is set and
7005 client receives a private message packet the client automatically
7006 replies to the sender with the away message.
7008 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7009 bug seemed to be the cause of recent problems when compiling
7012 * Added version detection support to SKE protocol specification
7013 and added the new changes to the SKE implementation as well.
7014 There were other minor changes in the SKE protocol as well.
7016 Many changes in lib/silcske/silcske.[ch] and in
7017 lib/silcske/payload.[ch].
7019 * Added ^U functionality, clear input line. Patch from cras.
7021 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Mainly small bugfixes on core library. Fixed some debugging
7024 logging and buffer overflow in silclog.c.
7026 * Updated config.sub and config.guess on the distribution tree.
7028 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Added command lagging support in server. Client may execute
7031 commands now only once in two seconds.
7033 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Optimized packet reception. MAC computation and checking is now
7036 also more optimized. A lot previously duplicated code is now
7037 used as generic by both client and server.
7039 * Fixed key pair generation in clientutil.c
7041 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7043 * Added into lib/silccore/silcbufutil.[ch] new function;
7044 silc_buffer_realloc.
7046 * Moved generic packet sending/encryption functions to
7047 lib/silccore/silcpacket.[ch] from client and server. Some
7048 rewriting of the functions.
7050 * Moved all generic packet reception/decryption functions to
7051 lib/silccore/silcpacket.[ch] from client and server. The
7052 packet processing is now much cleaner in both client and server.
7053 These were major changes in both client and server.
7055 * Created many common functions in server to do packet sending.
7056 Previously code were duplicated a lot, this has been removed
7059 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Rewrote major parts of the ID cache system. Don't know
7062 whether it is better now or not but at least the API is more
7065 * Major rewrite on ID cache stuff on client because of the ID
7066 cache API changes. Added idlist.c to client.
7068 * Also major rewrite on ID cache stuff on server as well.
7069 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7070 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7071 in hand, instead they are all put into the ID cache system now.
7072 All server_idlist_* routines uses ID cache now instead of
7073 traversing its own lists (those lists does not exist anymore).
7074 SilcIDList though still exists. Also, SilcXXXEntry's are
7077 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Finally made the SKE implementation compliant to the protocol
7080 specification. All mp integers are now binary encoded as
7081 opposed being HEX encoded.
7083 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7086 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7087 functions: silc_[encode/decode]_pem. Also added function
7088 silc_encode_pem_file to PEM encode with newlines ('\n') for
7091 * SILC public keys are now encoded either PEM or binary. Same
7092 option is for private keys as well. By default private keys
7093 are binary encoded and public keys PEM encoded. Silly HEX
7094 encoding were removed.
7096 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7097 function to create fingerprints.
7099 * Fixed a bug in SHA1; does not change the original data anymore.
7101 * Partly implemented INFO command on client and server side.
7102 Fixed CLEAR command. Changes to SERVER command; show current
7103 server(s) when giving command without arguments. Added
7104 VERSION command to client.
7106 * Added check to server that unregistered connections cannot
7107 execute commands (unless it is specificly allowed).
7109 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Fixed screen refresh.
7113 * Fixed channel joining bug from client. On some circumstances
7114 client tried to join to a channel it had already joined.
7116 * Added public key verification process into client's protocol.c.
7117 The client now verifies the public key from user and saves
7118 it into ~./silc/serverkeys/ directory.
7120 Added into: clientutil.[ch]: silc_client_verify_server_key.
7122 * Changed SKE protocol's silc_ske_initiator_finish function
7123 to accept callback function that verifies the received public
7124 key. Removed old silc_ske_verify_public_key function.
7126 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7129 silc_pkcs_private_key[_data]_set.
7131 * Made the password and public authentication more cleaner in
7132 server's protocol.c.
7134 * Removed historic and obsolete protocol `channel_auth' from
7135 both client and server.
7137 * Removed wrong way of sending command status messages from
7138 server to client in server's command.c. The old way violated
7139 protocol specification.
7141 Changes to silccore/silccommand.[ch]: removed
7142 silc_command_encode_status_payload -> not needed anymore,
7143 changed silc_command_encode_payload_va to accept extra
7144 argument on variable argument list. The argument type must
7145 now be provided to the function. Also, added new function:
7146 silc_command_encode_reply_payload_va which is same as
7147 normal command_encode_payload_va except command status type
7148 is provided as extra argument.
7150 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added ~./silc directory handling. The directory includes the
7153 public and private keys for the client.
7155 Added silc_client_check_silc_dir, silc_client_create_identifier
7156 and silc_client_load_keys.
7158 * Implemented SILC protocol compliant public key. Added public
7159 and private key saving to and loading from files.
7161 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7162 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7163 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7164 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7165 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7167 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7168 silc_pkcs_load_[public/private]_key.
7170 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Added silc_server_get_route (route.[ch]) to get connection
7173 data for the fastest route for given ID.
7175 * Implemented INVITE command on client and server. The command
7176 were re-defined in the SILC Protocol Specification and the
7177 implementation now complies with the specification.
7179 * Implemented PING command on client and server.
7181 * Implemented NAMES command on client and server. The server side
7182 supports currently only normal server not router server yet.
7183 Some changes to NAMES definition in SILC protocol specification.
7185 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Implemented LEAVE command on client and server.
7189 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7190 again. This change was made to the protocol as well. Server
7191 should not violate the protocol specification anymore.
7193 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7196 was tested. SOCKS4 was not but should work anyway.
