23 hash public keys and compare public keys in hash table. Affected
24 file lib/silcutil/silcutil.[ch].
26 * Added support for specifying multiple public keys for Client
27 connection section in server configuration file. This makes it
28 possible to accept multiple public keys from same host, or to
29 make a section that accepts any incoming host, and have the
30 accepted public keys listed in the section.
32 Added functions silc_sever_[find/get]_public_key, added the
33 support for this actually to all connection sections but only
34 the Client section is currently allowed to specify multiple

187 * Added `user_count' to the SilcChannelEntry which now tells the
188 number of users on the channel. The user count is now saved
189 in normal server of global channels as well. Affected files
190 silcd/server.c, idlist.h, packet_receive.c and command.c.
192 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

209 the SKE interface a bit.
211 * Fixed padding problem in PKCS#1. The padding was not actually
212 random since the random number generator was used incorrectly.
213 This security bug affects only when encrypting with PKCS#1, and
214 it is not currently used at all in SILC. SILC only use signing
215 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
217 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Rewrote the notify handling in Irssi SILC client to not call

283 * Added new configuration options and blocks:
284 keepalive_secs, reconnect_count, reconnect_interval,
285 reconnect_interval_max, reconnect_keep_trying and
286 require_reverser_lookup. Added ConnectionParam block, and
287 implemented the connection parameters when connecting as
288 initiator and when accepting connections as responder.

291 whether given configuration value has been given already.
293 Affected files silcd/serverconfig.[c], server.[c].
295 * Splitted the doc/example_silcd.conf.in. Separated the crypto
296 algorithm parts and created new file silcalgs.conf, that
297 is now included from the example_silcd.conf.in.
299 * Optimized the silc_server_connect_to_router_second to take
300 the connection configuration object from the SilcServerConnection
301 object instead of finding it during the connecting phase.
302 Added the configuration object to SilcServerConnection struct.
303 Affected files silcd/server_internal.h, server.c.

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

387 * Fixed the file transfer's key agreement payload to include
388 zero port also if the hostname is NULL because it could not
391 Call file transfer monitor callback now also if error occurs
392 during key agreement protocol.
394 Changed the silc_client_file_send interface to return the
395 SilcClientFileError instead of session id. The session ID
396 is returned into pointer provided as argument.
398 Check that the file exists locally before sending the
399 file transfer request at all.
401 Affected file lib/silcclient/client_ftp.c, silcapi.h.

413 file lib/silcutil/silclog.c.
415 * Fixed the channel message payload decryption in the function
416 silc_channel_message_payload_decrypt to not modify the original
417 buffer before it is verified that the message decrypted
418 correctly. Otherwise, next time it is called with correct
419 channel key it won't encrypt since the payload is corrupted.
420 Affected file lib/silccore/silcchannel.c.
422 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

465 users list to SilcHashTable. The affected files are
466 lib/silcclient/idlist.[ch].
468 * Fixed a bug in hash table tarversing. While the hash table
469 is traversed with SilcHashTableList the table must not be
470 rehashed. It is now guaranteed that auto rehashable tables
471 are not rehashed while tarversing the list. Also defined that
472 silc_hash_table_rehash must not be called while tarversing
473 the table. Added function silc_hash_table_list_reset that must
474 be called after the tarversing is over. The affected files are
475 lib/silcutil/silchashtable.[ch].
477 * Changed all hash table traversing to call the new
478 silc_hash_table_list_reset in server and in client library.
480 * Added function silc_client_on_channel to return the
481 SilcChannelUser entry if the specified client entry is joined
482 on the specified channel. This is exported to application as

492 lists correctly. Affected file silcd/command.c.
494 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
496 * When sending JOIN command to router for processing the
497 sender's old command identifier was not saved back to the
498 sender's command context, fixed now. The affected file is
501 * Create the key in JOIN command of the router did not return
502 the channel key, added check for this. Affected file is
505 * Fixed a channel ID update bug in JOIN command reply. Do
506 not directly upgrade the ID but call the function
507 silc_idlist_replace_channel_id if the ID was changed.
508 Affected file silcd/command_reply.c.
510 * Fixed memory leaks from command calling if it would fail.
511 Affected file silcd/command.c.

530 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Fixed a crash in server related to channel announcements.
533 Affected file silcd/server.c.
535 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Fixed memory leaks in silc_server_create_new_channel*
538 functions. Affected file silcd/server.c.
540 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
541 which ID was changed. This way the router will send the
542 user list for the channel again, and server won't be in
543 desync in some rare circumstances. Affected file is
544 silcd/packet_receive.c.
546 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

558 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
560 * Added lib/silcclient/client_ops_example.h as an template
561 file for application programmers to quickly start using
562 the SilcClientOperation functions in their application.
563 Updated the lib/silcclient/README as well to tell about this
564 nice file made available.
566 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Call silc_server_remove_from_channels when removing client
569 entry when NO_SUCH_CLIENT_ID was received. Affected file
570 is silcd/command_reply.c.
572 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Added server & router operator statistics updating. Affected
575 file silcd/packet_receive.c and silcd/command.c.
577 * Fixed the SERVER_SIGNOFF notify handling on normal server
578 not to save the history information for clients. Same was
579 fixed earlier in remove_clients_by_server function, but not
580 here. Affected file silcd/packet_receive.c.
582 * Raised the default connection-retry count from 4 to 7 in
583 server. Affected file silcd/server.h.
585 * Cancel any possible reconnect timeouts when we start the
586 key exchange. Affected file silcd/server.c.
588 * Do not reconnect on connection failure when SCONNECT was
589 given. Affected files silcd/server.[ch].
591 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
595 * Fixed the NICK command to always give the unformatted
596 nickname to the one giving the NICK command. If unformatted
597 nickname is cached already it will be formatted and the
598 local entry will always get the unformatted nickname.
599 Affected file lib/silcclient/idlist.c.
601 * Fixed some double frees from client library commands.
602 Affected file is lib/silcclient/command.c.
604 * Fixed CUMODE command in server to assure that no one can
605 change founder's mode than the founder itself, there was a
606 little bug. Affected file silcd/command.c.
608 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Removed the SilcClientCommandDestructor from the client
611 libary, it is not needed anymore. Affected files are
612 lib/silcclient/silcapi.h, command[_reply].[ch],
613 client_notify, idlist.c.
615 * Fixed GETKEY command to first resolve client, and then
616 resolve the server only if the client was not found, instead
617 of resolving both at the same time. Affected file is
618 lib/silcclient/command.c.
620 * Added silc_client_start_key_exchange_cb and lookup the
621 remote hostname and IP address before starting the key
622 exchange with server. The affected file is
623 lib/silcclient/client.c.
625 * The server's public key is now saved using the IP address
626 of the server and not the servername for the filename.
627 The hostname public key filename is checked as an fall back
628 method if the IP address based filename is not found.
630 Fixed the GETKEY command to save the fetched server key
633 Print the remote server's hostname now when new key is
634 received during connection process. Affected file is
635 irssi/src/silc/core/client_ops.c.
637 * Return always our own public key to the client if it asks
638 for it with GETKEY command. Affected file silcd/command.c.
640 * Removed the use_auto_addr variable from default config
641 file since it was in wrong section. Affected file is
644 * Fixed TOPIC_CHANGE notification to not route it when it
645 was sent using silc_server_send_notify_to_channel function.
646 Affected file silcd/command.c.
648 * Fixed silc_server_send_notify_kicked to send the kicker's
649 Client ID also, it was missing. Affected files are
650 silcd/command.c, silcd/packet_send.[ch].
652 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Do not save client history information in SERVER_SIGNOFF.
655 Fixes the bug in normal server that it does not detect
656 the client becoming valid after the server becomes back
657 online. Affected file silcd/server_util.c.
659 * Added `sock_error' field into the SilcSocketConnection
660 context. When error occurs during socket operation (read
661 or write) the error is saved. Added also new function
662 silc_socket_get_error to return human readable socket error
663 message. Affected files are lib/silcutil/silcsockconn.[ch],
664 lib/silcutil/unix/silcunixsockconn.c, and
665 lib/silcutil/win32/silcwin32sockconn.c.
667 * The server now prints the socket error message in the
668 signoff for client. Affected file silcd/server.c.
670 * Fixed the `created' channel information sending from router
671 to server in JOIN command. Checks now whether the channel
672 really was created or not and set it according that.
674 Fixed the JOIN command to use the client entry's current
675 ID during the joining procedure instead of the one it sent
676 in the command (it is checked though), since it can change
677 between the packet processing and command processing, and
678 would just case unnecessary pain in the client end. Affected
679 file silcd/command.c.
681 * Fixed a channel key payload sending to use correct channel
682 ID when the server was forced to change the channel's ID by
683 router. Router sent the key payload with the old Channel ID.
684 Affected file silcd/packet_receive.c.
686 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Call silc_server_save_channel_key only if the key payload
689 was provided in the JOIN command's command reply. Affected
690 file silcd/command_reply.c.
692 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
694 * Fixed silc_mp_sizeinbase to return the value correctly with
695 MPI. Affected file lib/silcmath/mp_mpi.c.
697 * Fixed the stop_server signal to correctly stop the scheduler
698 and gracefully stop the server when SIGTERM or SIGINT signals
699 are received. Affected file silcd/silcd.c.
701 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
703 * Simple handling of TERM and HUP signals. Also added some log
704 flushing call around. Affected file is
707 * Fixed small bugs in silclog.c. Now buffering output will take
708 effect after 10 seconds since startup: This will ensure that
709 no important startup messages are lost. Also output redirection
710 will preserve original format ([Date] [Type] message).
711 Affected file is lib/silcutil/silclog.c.
713 * Added two options to the config file, in the logging section:
714 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
715 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
717 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
719 * Do not print the warning about log files not being initialized
720 more than once to avoid excess logging. Affected file is
721 lib/silcutil/silclog.c.
723 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
724 the SIM copying in make install in Makefile.am.pre.
726 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
728 * Rewritten silclog APIs. Globally interesting changes follows:
729 silc_log_set_files() changed to silc_log_set_file().
730 silc_log_set_callbacks() changed to silc_log_set_callback().
731 ROBOdoc documented silclog header file.
732 SilcLogCb now returns bool to wether inihibit the default
733 handler or not (to keep the old behaviour return always TRUE).
734 The new APIs should also fix the problem of the
735 silcd_error.log file that was written in the current directory.
738 Log files streams will remain opened after silc_log_set_file()
739 call, means less CPU usage notably on high traffic servers.
740 File streams are now full buffered, and flushed to the disk
741 every 5 minutes, lesses HD activity and CPU usage.
742 Messages can be redirected, allowing admins to configure
743 one single logfile for all server messages.
744 the silc_log_quick global variable to activate fast-logging.
745 Affected files lib/silcutil/silclog.[ch]
747 * Changed some code to conform new silclog APIs. Affected
748 files are doc/example_silcd.conf.in, silcd/server.c
749 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
752 * Fixed a memory leak that could occur in some situations.
753 Affected file silcd/serverconfig.c.
755 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Added the silc_client_del_client to remove the client from
758 all channels as well. Affected file lib/silcclient/idlist.c.
760 * Fixed the client library to correctly remove the client
761 from all channels when the client entry is being destroyed.
762 Affected file lib/silcclient/client_notify.c, command.c.
764 * Added auto-nicking support to the client library. If the
765 applicatio now sets client->nickname it will be sent to the
766 server after connecting by the library. This way for example
767 SILCNICK (or IRCNICK) environment variables will have effect
768 and always change the nickname automatically to whatever
769 it is wanted. Affected file lib/silcclient/client.[ch].
771 * Renamed silc_server_command_bad_chars to the
772 silc_server_name_bad_chars and moved it to the
773 silcd/server_util.[ch]. Added also new function
774 silc_server_name_modify_bad to return nickname that
775 includes bad characters as new nickname without those
776 bad characters. This check and modify is now used in
777 silc_server_new_client when the username is initially set
778 as nickname, so it must be checked to be valid nickname.
779 Affected file silcd/packet_receive.c.
781 * The nickname length is now taken from the packet for real
782 and not trusted to strlen() since it clearly can return
783 wrong length for nickname including bad characters. This
784 also applies to channel names. Affected file silcd/command.c.
786 * Removed the lib/silcsilm/modules directory. Modules are now
787 compiled into the lib/silcsim. Fixed the copying of the
788 modules to follow symbolic links in Makefile.am.pre.
790 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
792 * Fixed silc_string_regexify list creation. Fixes bugs with
793 BAN and INVITE commands in server. The affected file is
794 lib/silcutil/unix/silcunixutil.c.
796 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Removed the command destructor entirely from the server's
799 command and command reply routines. It is not needed, and
800 its usage was buggy and caused crashes. Affected files are
801 silcd/command[_reply].[ch].
803 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Cancel protocol and NULL sock->protocol if timeout
806 occurred during protocol. Affected file silcd/server.c.
808 * Cancel protocol timeouts always before calling the final
809 callback, to assure that after final callback is called
810 no other state will be called for the protocol anymore.
811 Affected file silcd/protocol.c.
813 * Print error log if incoming connection configuration could
814 not be found. Affected file silcd/server.c.
816 * Fixed JOIN command to correctly save the founder mode
817 to the client on normal SILC server, when the channel
818 was created by the router. Affected file silcd/command.c.
820 * Fixed LIST command (hopefully) to send correct reply
821 packets. Affected file silcd/command.c.
823 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
825 * The silc_packet_receive_process now returns FALSE if the
826 read data was invalid packet, and TRUE if it was ok.
828 The server now checks that if unauthenticated connection
829 sends data and its processing fails the server will close
830 the connection since it could be a malicious flooder.
832 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
834 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Make sure the warning about error opening a log file is
837 printed only once and not everytime it fails (produces
838 too much useless log). Affected file lib/silcutil/silclog.c.
840 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
842 * Made the silc_server_daemonise() function more readable.
843 Affected file silcd/server.c.
845 * Pid file is now optional, the user may comment it out from
846 the config file. Removed define SILC_SERVER_PID_FILE, we
847 don't need a default any longer. Affected file
848 configure.in.pre, lib/Makefile.am.pre.
850 * Make some use of the pid file. The server now dies at startup
851 if it detects a valid pid file on his path. The server would
852 die anyway in this circumstance, because of the bind() failure.
853 Affected file silcd/silcd.c.
855 * No longer compiling lib/dotconf.
857 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Fixed JOIN command parsing not to crash. Affected file
860 lib/silcclient/command.c.
862 * Fied the NICK_CHANGE notify to add the new client entry
863 even it is resolved. This removes an <[unknown]> nick
864 thingy bug in the client. Affected file is
865 lib/silcclient/client_notify.c.
867 * Do not try to allocate 0 bytes (efence does not like it)
868 in lib/silccore/silccomand.c when encoding payload.
870 * Do not take IRCNICK as nickname in Irssi SILC client since
871 it is not possible to set nickname before hand connecting
872 the server (TODO has an entry about adding auto-nicking
875 * Changed the silc_server_command_pending to check whether
876 there already exists an pending entry with the specified
877 command, command identifier and pending callback. This is
878 to fix IDENTIFY and WHOIS related crashes that may register
879 multiple pending commands with same identifier. Affected
880 file silcd/command.c.
882 * Fixed the server to reconnect to the router even if it
883 was already reconnecting and EOF was received. This to
884 fix a possibility that the server wouldn't ever try to
885 auto-reconnect to the router. Affected file silcd/server.c.
887 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Fixed the server's password authentication to use the
890 length of the locally saved password, and not the one
891 sent in the packet. Affected file silcd/protocol.c.
893 * Fixed same password authentication problem in the
894 Authentication Payload handling routines in
895 lib/silccore/silcauth.c.
897 * Yet another password authentication problem fixed with
898 channel password handling in silcd/command.c.
900 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
902 * If first character of string in silc_parse_userfqdn is '@'
903 then do not parse it. Affected file is
904 lib/silcutil/silcutil.c.
906 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
908 * Fixed minor bug in IDENTIFY command reply sending, which
909 caused various weird problems during JOIN when it was
910 resolving names for users. Affected file silcd/command.c.
912 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Fixed the IDENTIFY command reply sending to chech better valid
915 clients. It was possible to send incomplete list of replies.
916 Affected file silcd/command.c.
918 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Added silc_client_command[s]_[un]register functions now to
921 dynamically register the commands in client library. Removed
922 the static table of commands. This allows the client library
923 to call commands without causing the application to know about
924 what commands library has called.
926 Removed the INFO command reply kludge to detect when the command
927 was called by library. Now library use its own command reply
928 function for INFO command.
930 Added function silc_client_command_call to call a command.
931 Application can use it to call command, not access the structure
934 Now all commands that are sent by the client library (not
935 explicitly sent by application) use own command reply functions.
937 Affected files around lib/silcclient/ and in
938 irssi/src/silc/core/.
940 * Fixed the WHOIS command reply sending to chech better valid
941 clients. It was possible to send incomplete list of replies.
943 Fixed the WHOIS and IDENTIFY to send the request to router
944 if normal server did not do it and did not find any results.
946 Affected file silcd/command.c.
948 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Moved the internal data from SilcClient context into its
951 own file, not accesible to application. Affected files
952 lib/silcclient/client.h and lib/silcclient/client_internal.h,
953 and other files in client library.
955 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
957 * Added doc/examples installation target in Makefile.am.pre.
960 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
962 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
963 commands the found client entry will be removed from the
964 cache, after notifying application about the error. Affected
965 file lib/silcclient/command_reply.c.
967 * Changed the /MSG to check for exact nickname user gave, and
968 not let `nick' match `nick@host' if it is only one found. Now,
969 user must type the exact nickname (like nick@host2) even if
970 there are no more than one same nicks found. This is to avoid
971 a possibility of sending nickname to wrong nickname since
972 `nick' could match `nick@host'. Affected file is
973 irssi/src/core/silc-servers.c.
975 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
977 * Do not print "you are now server operator" or similar when
978 giving /away command. Affected files are
979 irssi/src/silc/core/client_ops.c, silc-servers.h.
981 * Made the silc_server_command_pending_error_check to send
982 the same command reply payload it received back to the
983 original sender of the command. This way all arguments
984 that was received by the server will be received by the
985 client too. Affected file silcd/command.c.
987 * Added the silc_idcache_add to return the created cache entry
988 to a pointer. Affected file lib/silccore/silcidcache.[ch].
990 * Add global clients to expire if they are not on any channel.
991 This is because normal server will never know if they signoff
992 if they are not on any channel. The cache expiry will take
993 case of these entries. This is done by normal servers only.
994 The affected files are silcd/command_reply.c,
995 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
997 * If server receives invalid ID notification for WHOIS or
998 IDENTIFY and the ID exists in the lists, it is removed.
999 Affected file silcd/command_reply.c.
1001 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1002 in client then client entry that it matches is searched and
1003 the nickname is printed on the screen for user. Affected
1004 file irssi/src/silc/core/client_ops.c.
1006 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Use cache entry expire time in the LIST command reply to
1009 purge old entries from the cache after the LIST command
1010 reply has been received. This way we don't have non-existent
1011 entries in the cache for too long. Affected file is
1012 silcd/command_reply.c.
1014 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * If we are normal server, and we've not resolved client info
1017 in WHOIS or IDENTIFY from router, and it is global client,
1018 we'll check whether it is on some channel. If it is not
1019 then we cannot be sure about its validity and will resolve it
1020 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1021 file silcd/command.c.
1023 * Search channel by name (if possible) rather than by ID
1024 in IDENTIFY command's command reply. Affected file is
1025 silcd/command_reply.c.
1027 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1030 Updated specs and implemented it. Affected file silcd/command.c,
1031 silcd/packet_send.c and silcd/packet_receive.c.
1033 * Implemented the <founder auth> payload handling in the JOIN
1034 command. If provided all conditions for channel joining
1035 except requirement to provide correct passphrase can be
1036 overrided by the channel founder. Updated the protocol specs.
1037 Affected file silcd/command.c.
1039 Added support for founder auth in JOIN command in client
1040 library. Fixed the parsing of the JOIN command now to support
1041 all options as they should be. The affected file is
1042 lib/silcclient/command.c.
1044 * Optimized the WHOIS and IDENTIFY commands to send the request
1045 to router only if it includes nicknames or other names. If
1046 they include only IDs then check the local cache first before
1047 routing. Affected file is silcd/command.c.
1049 * Added channels topic announcements. Affected file is
1050 silcd/packet_receive.c and silcd/server.c.
1052 * Fixed the silc_server_send_notify_topic_set to really destine
1053 the packet to channel. Affected file silcd/packet_send.c.
1055 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1056 library. Affected file lib/silcclient/client_notify.c.
1058 * Added UMODE announcements. Affected file silcd/server.c.
1060 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Memory leak fixes in:
1064 lib/silcutil/silcsockconn.c
1065 lib/silcske/silcske.c
1066 lib/silcske/groups.c
1068 lib/silccrypt/silcpkcs.c
1069 lib/silccore/silccommand.c
1070 lib/silccore/silcidcache.c
1075 * ROBOdoc documented the lib/silcske/groups.h file and a
1076 bit changed the interface for better.
1078 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1080 * Update the client entry context in the ID cache after
1081 nick change. Affected file lib/silcclient/command.c.
1082 Fixes the CUMODE command when regaining founder privileges,
1083 and a little WHOIS problem.
1085 * Fixed silc_net_gethostbyname to correctly call the
1086 inet_ntop. Affected file lib/silcutil/silcnet.c.
1088 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1090 * Added IPv6 support checking to the configure.in.pre, added
1091 also --enable-ipv6 option to override the check. Affected
1092 file configure.in.pre.
1094 * The silc_thread_create now calls the start function
1095 directly if threads support is not compiled in. Removes
1096 ugly #ifdef's from generic code. Affected files are
1097 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1099 * Added silc_net_gethostby[name/addr]_async to asynchronously
1100 resolve. Affected files are lib/silcutil/silcnet.[ch].
1102 * Added support for rendering IPv6 based server, client and
1103 channel IDs. Affected file lib/silcutil/silcutil.c.

1108 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1110 * Added silc_net_gethostby[addr/name] into the
1111 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1112 routines. Added silc_net_is_ip[4/6]. Affected file is
1113 lib/silcutil/unix/silcunixnet.c. All routines that take
1114 address as argument now supports both IPv4 and IPv6 addresses.
1116 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1118 * Fixed LIST command reply sending in server. Affected file
1121 * Server now sends the kicker's client ID in the KICK notify
1122 to the kicked client. Affected file silcd/command.c.
1124 * The client library now parses the kickers client ID and
1125 UI displays it. Affected files lib/silcclient/client_notify.c
1126 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1128 * Made all payload parsing function prototypes consistent.
1129 They all take now const unsigned char * and uint32 pair as
1130 the payload data instead of SilcBuffer. Changes all around
1131 the source tree. Other unsigned char* -> const unsigned char*
1132 changes around the tree as well.
1134 * Optimized SFTP client and server packet sending not to
1135 allocate new buffer for each packet but to recycle the
1136 first allocated buffer. Affected files are
1137 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1139 * Optimized the SFTP client to use SilcList instead of
1140 SilcDList for requests, because it is faster. Affected file
1141 is lib/silcsftp/sftp_client.c.
1143 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1144 into lib/silccore/silcid.[ch].
1146 Renamed silcpayload.[ch] into silcargument.[ch].
1148 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * If client entry is deleted with active key agreement
1151 session, abort the session.
1153 The silc_client_abort_key_agreement now calls the completion
1154 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1156 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1159 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Don't use __restrict in older GCC's. Affected file is
1162 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1164 * silc_net_localhost now attempts to reverse lookup the
1165 IP/hostname. Affected file lib/silcutil/silcnet.c.
1167 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1168 command. It can be used to gain founder privileges at
1169 the same time when joining the channel.
1171 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1172 kicker's client ID as well. Updated protocol specs.
1174 Defined that the server must send SILC_COMMAND_IDENTIFY
1175 command reply with error status to client who sent
1176 private message with invalid client ID.
1178 Updated the protocol specification.
1180 * Added silc_server_send_command_reply to send any
1181 command reply. Affected file silcd/packet_send.[ch].
1183 * Added silc_id_payload_encode_data to encode ID payload
1184 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1186 * The server now send IDENTIFY command reply with error
1187 status if client ID in private message is invalid. Affected
1188 file silcd/packet_receive.c.
1190 * Save the server key file with server's IP address in
1191 the filename instead of hostname. The affected file is
1192 irssi/src/silc/core/client_ops.c.
1194 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1199 * Added libtool support for compiling shared objects in
1200 lib/silcsim. Affected file configure.in.pre and
1201 lib/silcsim/Makefile.am. Original patch by cras.
1203 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Pid file configuration, and server's config file fixes
1206 patch by toma. Updated CREDITS file.
1208 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed silc_client_channel_message to not try to decrypt
1211 the message twice if it resolved the destination client
1212 information. This could cause of dropping one channel
1213 message. Affected file lib/silcclient/client_channel.c.
1215 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1218 lib/silcclient/client.c. This function is used when the SILC
1219 Client is run under some other scheduler, or event loop or
1220 main loop. On GUI applications, for example this may be
1221 desired to used to run the client under the GUI application's
1222 main loop. Typically the GUI application would register an
1223 idle task that calls this function multiple times in a second
1224 to quickly process the SILC specific data.
1226 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1228 * Fixed silc_server_drop() for dropping the supplementary
1229 groups as well, this could cause a security hole on some
1232 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1234 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1237 * Write PID file after dropping privileges. Added -F option
1238 to run server on foreground. A patch by debolaz.
1239 Affected files silcd/server.c, silcd/silcd.c.
1241 * Fixed MOTD to return the MOTD file server name. Affected
1242 file silcd/command.c.
1244 * Added INFO command reply handling to the Irssi SILC Client.
1245 Affected file irssi/src/silc/core/client_ops.c.
1247 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Fixed the silc_idcache_list_* routines to really support
1250 the dynamic list. Fixes a crash. Affected file is
1251 lib/silccore/silcidcache.c.
1253 * Fixed the LIST command reply to really call LIST command's
1254 pending callbacks. Affected file silcd/command_reply.c.
1256 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Update conn->local_entry->nickname after giving NICK
1259 command. Affected file lib/silcclient/command.c.
1261 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1263 * Added the [pid] option to the silcd configuration file
1265 Affected files: serverconfig.[ch] and silcd.c
1267 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Save fingerprint in WHOIS command reply in server.
1270 Affected file silcd/command_reply.c.
1272 * Fixed NICK commands pending callback registration.
1273 Affected file lib/silcclient/command.c.
1275 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Use ++server->cmd_ident when sending commands in server,
1278 instead of random number. Affected file silcd/command.c.
1280 * Fixed GETKEY command reply to call actually GETKEY pending
1281 command callbacks. Affected file silcd/command_reply.c.
1283 * A bit stricter check for nicknames. Check for same nickname
1284 in NICK command also. Affected file silcd/command.c.
1286 * Do not call INFO command everytime client ID changes, only
1287 during first connecting. Affected file lib/silcclient/client.c.
1289 * Set the new nickname only after successful command reply for
1290 NICK command is returned by server. Affected file
1291 lib/silcclient/command.c.
1293 * Remove nicknames from nicklist during server_signoff notify.
1294 Should fix /NAMES bit more. The affected file is
1295 irssi/src/silc/core/silc-channels.c.
1297 * Added `fingerprint' field to the SilcIDListData in the
1298 silcd/idlist.h to hold the fingerprint of the client's
1301 Send the fingerprint of the client's public key in WHOIS
1304 Affected files silcd/command.c, and silcd/idlist.[ch].
1306 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1307 create fingerprint from given data.
1309 * Show the fingerprint of the client's public key in WHOIS.
1310 Affected files irssi/src/module-formats.[ch] and
1311 irssi/src/silc/core/client_ops.c.
1313 * Format the multiple same nicknames also during JOIN and
1314 NICK_CHANGE notifys. Affected file is
1315 lib/silcclient/client_notify.c.
1317 * Do not print error on screen for invalid private message
1318 payload since it can come if someone is sending private
1319 messages with wrong key. Affected file
1320 lib/silccore/silcprivate.c.
1322 * Fixed multiple concurrent /PING crash. Affected file
1323 lib/silcclient/command.c.
1325 * Changed the wrong ID encoding. All IP addresses must be
1326 in MSB first order in encoded format. They were encoded
1327 wrong and was in LSB format. Affected files are
1328 silcd/serverid.c, lib/silcutil/silcutil.c.
1330 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1332 * Call the `connect' client operation through the scheduler
1333 in case of error. Affected file lib/silcclient/client.c.
1335 * Call the `failure' client operation even if the error
1336 occurred locally during a protocol. Affected file is
1337 lib/silcclient/protocol.c.
1339 * Added support of sending LIST command to router from normal
1340 server. This way normal server can get list of all channels
1341 in the network too. Fixed the channel list sending in the
1342 server too. Affected files are silcd/command.c, and
1343 silcd/command_reply.[ch].
1345 * Added silc_server_update_channels_by_server and
1346 silc_server_remove_channels_by_server. They are used during
1347 disconnection of primary router and in backup router protocol.
1348 Affected file silcd/server_util.[ch], silcd/server.c and
1349 silcd/server_backup.c.
1351 * Fixed channel adding to global list in IDENTIFY command
1352 reply in server. Affected file silcd/command_reply.c.
1354 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * If the incoming packet type is REKEY or REKEY_DONE process
1357 that packet always synchronously. Fixes yet another MAC
1358 failed error on slow (dialup) connections. Affected file
1359 lib/silcclient/client.c and silcd/server.c.
1361 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Call check_version SKE callback for initiator too. Affected
1364 file lib/silcske/silcske.c.
1366 * Implemented fix for security hole found in the SKE that was
1367 fixed in the specification few days back; the initiator's
1368 public key is now added to the HASH value computation.
1369 Added backwards support for the old way of doing it too, for
1370 old clients and old servers. Affected file is
1371 lib/silcske/silcske.c.
1373 * Enabled mutual authentication by default in SKE. If initiator
1374 is not providing mutual authentication the responder will
1375 force it. This will provide the proof of posession of the
1376 private key for responder. The affected files are
1377 lib/silcclient/protocol.c and silcd/protocol.c.
1379 * Do not cache anymore the server's public key during SKE.
1380 We do mutual authentication so the proof of posession of
1381 private key is done, and if the server is authenticated in
1382 conn auth protocol with public key we must have the public
1383 key already. Affected file silcd/protocol.c.
1385 * Added new global debug variable: silc_debug_hexdump. If
1386 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1387 file lib/silcutil/silclog.[ch].
1389 * Fixed compilation warning due to char * -> const char *.
1390 Affected files lib/silcutil/silcnet.h, and
1391 lib/silccore/silcauth.[ch].
1393 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Fixed CMODE command when new channel key was created. If
1396 the creation failed the old key was removed. Next time giving
1397 same command would crash the server since the old key was
1398 freed already. Affected file silcd/command.c.
1400 * Fixed the silc_server_announce_get_channels to not crash
1401 on reconnect. Affected file silcd/server.c.
1403 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Added silc_log_set_debug_string function to set a regex
1406 string to match for debug output. Only the function names,
1407 or filenames matching the given debug string is actually
1408 printed. This way it is possible to filter out those debug
1409 strings that user is not interested in.
1411 Fixed a bug in silc_string_regexify.
1413 Affected files lib/silcutil/silclog.[ch], and
1414 lib/silcutil/unix/silcunixutil.c.
1416 * Changed the -d options in both server and Irssi SILC client
1417 to take the debug string as argument. Affected files
1418 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1420 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Added silc_hash_babbleprint to create a Bubble Babble
1423 Encoded fingerprint. The encoding is developed by Antti
1424 Huima (draft-huima-babble-01.txt), and it creates human
1425 readable strings out of binary data. Affected file
1426 lib/silccrypt/silchash.[ch].
1428 * Print the babble print now in addition of fingerprint as well
1429 in Irssi SILC client. Affected files are
1430 irssi/src/fe-common/silc/module-formats.[ch],
1431 irssi/src/fe-common/silc/core/client_ops.c.
1433 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Fixed a security problem found in SKE. The initiator's
1436 public key too is now added to the HASH hash value creation
1437 which is signed by the responder to create the SIGN value.
1438 This will prevent anyone in the middle to lie to the responder
1439 about the initiator's public key. If this is done now, the
1440 man in the middle will get caught. Updated the protocol
1443 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Better installation directory handling. Configure module
1446 paths and other paths automatically to example_silc* files
1447 in doc/. A patch by toma.
1449 * Fixed compiler warning from MPI library, and from SILC RNG.
1452 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1453 It can be configured with ./configure. A patch by toma.
1455 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Find correct make to use in prepare-clean. A patch by
1458 toma. Affected file prepare-clean.
1460 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1462 * Added irssi variables use_auto_addr, auto_bind_ip,
1463 auto_bind_port and auto_public_ip.
1465 * Changed the interface for silc_client_send_key_agreement
1466 in lib/silcclient/silcapi.h
1470 irssi/src/silc/core/silc-core.c
1472 lib/silcclient/silcapi.h
1473 irssi/src/silc/core/silc-channels.c
1474 lib/silcclient/client_keyagr.c
1477 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Added silc_pkcs_public_key_compare to compare two
1480 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1482 * Check that the client who set the founder mode on the
1483 channel is the same client that is giving the founder
1484 mode to itself. It is done by comparing the saved public
1485 key (it is saved even in the authentication is passphrase).
1486 Affected file silcd/command.c.
1488 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1490 * Do not process packet for disconnected socket connection.
1491 Affected file lib/silccore/silcpacket.c.
1493 * Process the DISCONNECT packet through scheduler in the
1494 client library. Affected file lib/silcclient/client.c.
1496 * Fixed the silc_client_packet_parse to not to increase
1497 the packet sequence number if the conn->sock and the
1498 current socket connection is not same. This can happen
1499 for example during key agreement when the conn includes
1500 multiple socket connections (listeners). Affected file
1501 lib/silcclient/client.c.
1503 * The sender of the file transfer request now provides also
1504 the pointer (listener) for the key exchange protocol. If
1505 the listener cannot be created then it sends empty key
1506 agreement and lets the receiver provide the listener.
1508 Added `local_ip' and `local_port' arguments to the
1509 silc_client_file_send. If they are provided they are used,
1510 if not then it will attempt to find local IP address, if
1511 not found or bind fails then the remote client will provide
1514 Affected files are lib/silcclient/client_ftp.c and
1515 lib/silcclient/silcapi.h.
1517 * Extended the FILE SEND command to support defining the
1518 local IP and port for key exchange listener. They are
1519 optional. Affected file irssi/src/silc/core/silc-servers.c.
1521 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Defined to WHOIS command reply the sending of fingerprint
1524 of the client's public key (if the proof of posession of the
1525 corresponding private key is verified by the server).
1526 Updated to the protocol specification.
1528 * Added support of receiving the client's public key's
1529 fingerprint in command reply in client library. Affected
1530 file is lib/silcclient/command_reply.c, and
1531 lib/silcclient/idlist.[ch].
1533 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Do not send over 128 chars long nickname to the server
1536 in NICK command. Affected file lib/silcclient/command.c.
1538 * Do not send over 256 chars long channel names to the server
1539 in JOIN command. Affected file lib/silcclient/command.c.
1541 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Assure that silc_server_close_connection cannot be called
1544 twice for same socket context. Affected file is
1547 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1549 * Send error message to application if opening file for
1550 writing during file transfer fails. Affected file is
1551 lib/silcclient/client_ftp.c.
1553 Remove all file transfer sessions for a client that we're
1554 removing from ID cache.
1556 Affected file is lib/silcclient/client_ftp.c.
1558 * Fixed silc_net_addr2bin to return correct address. Affected
1559 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1561 * Fixed file transfer session removing on signoff notify.
1562 Affected file irssi/src/silc/core/silc-servers.c.
1564 * Added the SilcClientFileError to be returned in the monitor
1565 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1566 Affected file lib/silcclient/silcapi.h.
1568 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * Fixed a crash in silc_client_ftp_free_sessions and
1571 silc_client_ftp_session_free_client. Affected file
1572 lib/silcclient/client_ftp.c.
1574 * Added `disabled' field in the SilcChannelEntry in the server
1575 to indicate if the server entry is disabled. Affected file
1576 silcd/idlist.h, silcd/command[_reply].c.
1578 * SILC server adds now /var/run/silcd.pid everytime it is
1579 started. Affected file silcd/silcd.c.
1581 * Added silc_server_packet_send_clients to send a packet to
1582 the provided table of client entries. Affected file
1583 silcd/packet_send.[ch].
1585 * Fixed a crash in client resolving in client_prvmsg.c in
1586 client library. Affected file lib/silcclient/client_prvmsg.c.
1588 * Do not actually remove the client directly from ID cache
1589 during SERVER_SIGNOFF, but invalidate it. This way we
1590 preserve the WHOWAS info for the client. Affected file
1591 silcd/server_util.c.
1593 * Fixed SERVER_SIGNOFF notify handling in the server. The
1594 server is now able to process incoming SERVER_SIGNOFF notify
1595 for a server that it doesn't even know about. It will remove
1596 the clients provided in the notify. Affected file
1597 silcd/packet_receive.c.
1599 * Check for partial packet in data queue after every packet that
1600 was found from the queue. Return and wait for more data if
1601 there is partial data in queue. Affected file is
1602 lib/silccore/silcpacket.c.
1604 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Added SilcClietFileError enum to indicate error in
1607 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1608 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1609 Affected files lib/silcclient/silcapi.h and
1610 lib/silcclient/client_ftp.c.
1612 * Check that newsize in silc_buffer_realloc is larger than
1613 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1615 * Added better monitor of file transfers. It now monitors
1616 key agreement protocol during the file transfer too. Added
1617 error reporting too. Affected files
1618 irssi/src/silc/core/silc-servers.c,
1619 irssi/src/fe-common/silc/module-formats.[ch].
1621 * Wrote a help file for FILE command.
1623 * Added silc_rng_global_get_byte_fast to get not-so-secure
1624 random data as fast as possible. Random data is read from
1625 /dev/urandom if available and from the SILC RNG if not
1626 available. It is used in padding generation. Affected file
1627 lib/silccrypt/silcrng.[ch].
1629 * All packets in client library are now processed synchronously.
1630 Optimized packet processing a lot. Affected file
1631 lib/silcclient/client.c.
1633 * All server connection packets are processing synchronously
1634 now in server, to optimize packet processing. Affected file
1637 * Include files are installed now only in Toolkit distribution
1638 if make install is given. Affected files: all Makefile.am's.

1642 * Assure that silc_client_notify_by_server_resolve does not
1643 resolve the client information multiple times. If it cannot
1644 be found by the first it cannot be found at all. Affected
1645 file lib/silcclient/client_notify.c.
1647 * Fixed WHOWAS command reply calling. Affected file
1648 lib/silcclient/command_reply.c.
1650 * Removed all references to silc_idlist_get_client from the
1651 Irssi SILC client since that call is internal call used by
1652 the library. The Irssi SILC client will use now client
1653 retrieval functions found in silcapi.h.
1655 * Fixed a bug in resolving nickname info before sending
1656 private message. It used freed memory. Affected file
1657 irssi/src/silc/core/silc-servers.c.

1678 * Added silc_net_localip to return local host's IP address.
1679 Affected file lib/silcutil/silcnet.[ch].
1681 * If key exchange or rekey protocol is active for a connection
1682 parse all packets syncronously since there might be packets
1683 in packet queue that we are not able to process without first
1684 processing packets before them. Affected file silcd/server,
1685 lib/silcclient/client.c.
1687 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1688 whether library should continue processing the packet.
1689 Affected file lib/silccore/silcpacket.h.

1735 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1736 is incomplete and is being resolved, it won't be resolved
1739 Make sure also that USERS command reply does not resolve
1740 twice information. Affected file is
1741 lib/silcclient/command_reply.c.
1743 Make sure that silc_client_get_clients_by_list does not
1744 resolve twice same information.
1746 * Check for valid client->id in the silc_server_free_client_data.
1747 Affected file silcd/server.c.
1749 * Fixed /GETKEY nick@server not to crash if the server entry
1750 is not found. Affected file lib/silcclient/command.c.
1752 * Fixed the silc_server_check_cmode_rights to check the
1753 requested modes correctly. Affected file silcd/command.c.

1757 * Better checks for non-printable chars in nick added.
1758 Affected file silcd/command.c.
1760 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Call the silc_server_udpate_servers_by_server in the
1763 primary router that comes back online in the backup resuming
1764 protocol. Otherwise it routes packets wrong. Affected file
1765 silcd/server_util.[ch], silcd/server_backup.c.
1767 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1770 lib/silcutil/silcbuffmt.[ch].
1772 * Redefined the SILC packet header to include the padding
1773 length. Affected file lib/silccore/silcpacket.[ch].
1775 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1776 length for maximum padding up to 128 bytes). Affected
1777 file lib/silccore/silcpacket.h.
1779 * Removed all backwards support for old 0.5.x MAC thingies.
1780 The SILC packet header change makes it impossible to be
1781 backwards compatible.
1783 * Send the ENDING packet with timeout in the backup resuming
1784 protocol. This is to assure that all routers has connected
1785 to the primary router. Affected file silcd/server_backup.c.
1787 * Changed the RNG to take the first IV from random data. It
1788 used to take it from zero actually. Changed the RNG also
1789 to use /dev/urandom during session. /dev/random is used
1790 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1792 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Changed the SILC packet header to have the first two bytes
1795 (the packet length) encrypted. Affected files aroung the
1796 code tree, lib/silccore/silcpacket.[ch]. Removed the
1797 SilcPacketCheckDecrypt callback. It is not needed anymore
1798 since the silc_packet_receive_process will determine now
1799 whether the packet is normal or special.
1801 * Implemented the unidirectional MAC keys. Affected files
1802 lib/silcske/silcske.c, silcd/protocol.c and
1803 lib/silcclient/protocol.c.
1805 * Implemented the packet sequence number to the MAC computation.
1806 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1807 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1808 lib/silcclient/protocol.c.
1810 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Allow backup router to announce servers. All servers
1813 announced by backup router are added to the global list
1814 automatically. Update hte server's socket to our primary
1815 router also when backup router announces a server.
1816 Affected file silcd/packet_receive.c.
1818 * Do not update the client->router in the function
1819 silc_server_udpate_clients_by_server if the client is on
1820 global list. We might fail to find any specific server
1821 for locally connected clients and local cell clients. They
1822 should still use the `from' and not `to' as client->router.
1823 This fixes backup router resuming protocol. Affected file
1824 silcd/server_util.c.
1826 * Decrease channel statistics count only if the channel
1827 deletion worked. Affected files are silcd/server.c and
1828 silcd/server_util.c.
1830 * Added silc_server_update_servers_by_server to update origin
1831 of all server entries. Used during backup router protocol.
1832 Affected files silcd/server_util.[ch], silcd/server.c. and
1833 silcd/backup_router.c.
1835 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1836 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1837 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1838 lib/silccrypt/silchmac.c.
1840 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Assure that router cannot reroute the same channel message
1843 to the sender. Affected file silcd/packet_receive.c.
1845 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Made better checks that the channel message is not sent
1848 to the router it came from. Affected file is
1849 silcd/packet_send.c. Fixed memory leak too.
1851 * Announce informations for incoming router connection, but
1852 only after checking if it is replaced by backup router.
1853 Affected file silcd/packet_receive.c.
1855 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Fixed the backup resuming protocol to work in multiple
1858 router environment. Affected file silcd/server_backup.c.
1860 * Route packet only to one router in the function
1861 silc_server_packet_send_to_channel. Affected file is
1862 silcd/packet_send.c.
1864 * Fixed silc_server_send_notify_dest to set the broadcast
1865 flag. Fixed the silc_server_send_notify_topic to actually
1866 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1867 Affected file silcd/packet_send.c.
1869 * Changed the SFTP Filesystem interface. Changed the
1870 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1871 the filesystem operation function. The SilcSFTPFilesystem
1872 is now a context that is allocated by all filesystem allocation
1873 functions and it already includes the operations structure
1874 and filesystem specific context. It is given as argument
1875 now to the silc_sftp_server_start. This made the interface
1876 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1877 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1879 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Changed the backup router adding and getting interfaces
1882 in the server. The router that will be replaced by the
1883 specified backup router is now sent as argument. Affected
1884 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1887 * Added silc_net_addr2bin_ne to return the binary form of
1888 the IP address in network byte order. Affected files
1889 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1891 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Check for existing server ID in silc_server_new_server
1894 and in silc_server_connect_to_router_final and remove the
1895 old entry if it exists. Affected file silcd/packet_receive.c,
1898 * Send the channel message always to only one router, either
1899 in upstream or downstream. Affected file is
1900 silcd/packet_send.c.
1902 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Wrote the definition of the backup resuming protocol to the
1905 protocol specification.
1907 * Removed one redundant channel key generation from normal
1908 server during joining procedure. Removed one redundant
1909 channel key sending from server to router during joining
1910 procedure. Affected file silcd/command.c.
1912 * Made minor bugfixes to the backup router resuming protocol.
1913 Affected file silcd/server_backup.c, server.c.

1918 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1921 * Implemented the backup resuming protocol that is used to
1922 resume the primary router position in the cell after the
1923 primary router comes back online. Affected files
1924 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1925 and silcd/server_util.[ch].
1927 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Sleep two (2) seconds after sending QUIT command to server.
1930 Affected file lib/silcclient/command.c.
1932 * Assure that if outgoing data buffer is pending do not force
1933 send any data. Affected file silcd/packet_send.c.
1935 * Assure that if outgoing data buffer is pending do not force
1936 send any data. Affected file lib/silcclient/client.c.
1938 * Implemented the backup router support when the primary router
1939 goes down. The servers and routers can now use the backup
1940 router as new primary router without loosing connectivity.
1942 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1945 in the server to indicate disabled entry. All data read
1946 from the connection will be ignored and no data is sent
1947 for entry that is disabled. Affected files are
1948 silcd/idlist.h, silcd/server.c.
1950 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Created SFTP client and server test programs in the
1953 lib/silcsftp/tests directory.
1955 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Implemented memory filesystem (virtual filesystem) for
1958 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1961 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Implemented the SFTP (SSH File Transfer Protocol) to the
1964 lib/silcsftp. It includes SFTP client and SFTP server
1967 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Moved lib/silccore/silcprotocol.[ch] to the
1970 lib/silcutil library.
1972 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1973 take variable argument list pointer as argument. Affected
1974 file lib/silcutil/silcbuffmt.[ch].
1976 * Added silc_buffer_set function that is used to set data
1977 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1978 Affected file lib/silcutil/silcbuffer.h.
1980 * Changed various routines in the core library to use the new
1981 silc_buffer_set instead of allocating new buffer only for
1984 * Added 64-bit value formatting and unformatting support to the
1985 silc_buffer_[un]format routines. Affected file is
1986 lib/silcutil/silcbuffmt.[ch].
1988 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1989 to includes/bitmove.h.
1991 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Fixed channel user mode saving in client library. Affected
1994 file lib/silcclient/command[_reply].c.
1996 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Defined the file transfer to the SILC Protocol. Added
1999 new packet type SILC_PACKET_FTP and defined File Transfer
2000 Payload. The mandatory file transfer protocol is SFTP
2001 (SSH File Transfer Protocol). Affected file in addition
2002 of the internet draft is lib/silccore/silcpacket.h.
2004 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2005 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2006 is used as part of backup router protocol when the primary
2007 router of the cell is back online and wishes to resume
2008 the position as primary router.
2010 * Redefined the MAC generation keys in the protocol. The
2011 same key is not used anymore in both direction. Both
2012 direction will now use different keys for sending and
2013 receiving. This fixes a potential security flaw. This
2014 change causes incompatibilities in the protocol.
2016 * Redefined also the MAC computation from the packet.
2017 An packet sequence number is now added to the MAC
2018 computation. This prevents possible replay attacks against
2019 the protocol. This change too causes incompatibilities
2022 Added `sequence' field to the SilcPacketContext to hold
2023 the current sequence number for the packet.
2025 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Added `created' field to the SilcIDListData in the file
2028 silcd/idlist.h to indicate the time when the entry was
2031 * Added `created' field to the SilcChannelEntry too. Affected
2032 file silcd/idlist.h.
2034 * Added `creation_time' aguments to all the announcement functions
2035 in the server. If it is provided then only the entries that
2036 was created after the provided time frame are actually
2037 announced. Affected file silcd/server.[ch].
2039 * The protocol says that the Channel ID's IP address must be
2040 based on the router's IP address. Added check for this in
2041 the silc_server_new_channel when processing incoming New Channel
2042 Payload. Affected file silcd/packet_receive.c.
2044 * Print out the correct version with --version in SILC client.
2045 Affected file irssi/src/silc/core/silc-core.c.
2047 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Fixed WHOWAS command to check for completnes of the client
2050 entry always, not just when the command is coming from client.
2051 Affected file silcd/command.c.
2053 * Added new function silc_server_packet_queue_purge to purge the
2054 outgoing data queue to the network. After the function returns
2055 it is guaranteed that the outgoing packet queue is empty.
2056 Affected file silcd/packet_send.[ch].
2058 * Purge the outgoing packet queue in the rekey protocol's final
2059 callback to assure that all rekey packets go to the network
2060 before quitting the protocol. Affected file silcd/server.c.
2062 * Added silc_client_packet_queue_parse as similar function as
2063 in server to the client library. The affected file is
2064 lib/silcclient/client.c.
2066 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Splitted silcd/server.c and created silcd/server_util.[ch]
2069 for utility functions.
2071 * Added new socket flag SILC_SF_DISABLED to indicate that the
2072 connection is open but nothing can be sent to or received from
2073 the connection. Affected file lib/silcutil/silsockconn.[ch].
2074 The checking for disabled socket is checked in the low level
2075 silc_socket_write and silc_socket_read functions.
2077 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Allow only nicknames and channel names that fits into the
2080 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2082 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * When processing JOIN command reply in server check that if
2085 the channel exists in our global list we'll move it the local
2086 list. Affected file silcd/command_reply.c.
2088 * Fixed the check whether client is joined on the channel already
2089 in JOIN command. Affected file lib/silcclient/command.c.
2091 * Fixed the JOIN command reply to check whether the channel
2092 already exists. Affected file lib/silcclient/command_reply.c.
2094 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Added silc_ske_status_string to map the SKE error numbers
2097 to readable strings. The affected files are
2098 lib/silcske/silcske[_status].[ch].
2100 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Do not show the private channels on the WHOIS channel list
2103 as it is not allowed by the protocol. The affected file is
2106 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Assure that the packet length digged from the actual packet
2109 is something sensible in the silc_packet_decrypt_rest_special
2110 in lib/silccrypt/silcpacket.c.
2112 * Free and NULL the allocated pointer in silc_hmac_alloc if
2113 the HMAC allocation fails. The affected file is
2114 lib/silccrypt/silchmac.c.
2116 * Print the selected security properties to the log files in
2117 the server. Affected file silcd/protocol.c.
2119 * Add SKE's reference counter even if calling the completion
2120 callback manually. Otherwise it goes negative, although it
2121 does not cause any problems. The affected file is
2122 lib/silcske/silcske.c.
2124 * Remove the client entry with short timeout after giving the
2125 KILL command. Affected file lib/silcclient/command.c.
2127 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2128 case all found clients are already disconnected (WHOWAS would
2129 found them) in the server. Affected file silcd/command.c.
2131 * Update the last_receive (time of last data received) to be
2132 updated only when received private or channel message so that
2133 the idle time showed in WHOIS makes more sense.
2135 * Added boolean field `valid' in to the SilcClientEntry in the
2136 client library to indicate whether the entry is valid or not.
2137 This fixes the nickname change bug on channel when changing
2138 the nickname to be same than the old (like nick to Nick) the
2139 nickname formatter doesn't set the new nick anymore to Nick@host.
2140 Affected file lib/silcclient/idlist.[ch].
2142 * Now actually fixed the nickname changing on disconnection.
2143 Added new function silc_change_nick to the Irssi SILC Client.
2144 Affected file irssi/src/silc/core/client_ops.c,
2145 irssi/src/silc/core/silc-nicklist.[ch].
2147 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Check that the public key exists in the GETKEY command before
2150 trying to encode it. Affected file silcd/command.c.
2152 * Print some notifications on received public keys with GETKEY
2153 command in the Irssi SILC Client. Affected files are
2154 irssi/src/fe-common/silc/module-formats.[ch],
2155 irssi/src/silc/core/client_ops.c.
2157 * Use IDENTIFY command to resolve the server information in the
2158 GETKEY command instead of INFO command. Affected file
2159 lib/silcclient/command.c.
2161 * All command reply functions in the client library now calls
2162 the pending command reply callbacks even if an error has
2163 occurred. The server has done this a long time and now it was
2164 time to move the client library to this as well. Now all
2165 errors can be delivered back to the pending command reply
2166 callbacks if necessary. Affected files are
2167 lib/silcclient/command[_reply].[ch].
2169 * Change the nickname on disconnection back to the username
2170 because in reconnect the server will enforce it to it anyway.
2171 Affected file irssi/src/silc/core/silc-servers.c.
2173 * Fixed a config file parsing bug in the Irssi SILC client.
2174 Affected file irssi/src/silc/core/clientconfig.c.
2176 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * When printing the channel mode on JOIN, verify that the
2179 channel key and channel's HMAC are valid. Affected file
2180 irssi/src/silc/core/client_ops.c.
2182 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2185 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2186 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2188 * Removed channel key rekey task deleting from the function
2189 silc_server_save_channel_key. Affected file silcd/server.c.
2190 Added explicit timeout task context instead that is used to
2191 delete the task if we are registering a new task before the
2192 new task has elapsed.
2194 * When channel key rekey occurs the client library now saves
2195 the old channel key for a short period of time (10 seconds) and
2196 is able to use it in case some is still sending channel
2197 messages encrypted with the old key after the rekey. Affected
2198 file lib/silcclient/[idlist.h|client_channel.c].
2200 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Added check to the silc_server_new_id_real to not accept
2203 new ID if it is the sender's own ID. Affected file is
2204 silcd/packet_receive.c.
2206 * Assure that we do not announce ourself or the one we've
2207 sending our announcements when we're router and are announcing
2208 servers to our primary router. Affected file silcd/server.c.
2210 * Fixed silc_server_command_identify_check_client to assemble
2211 correct WHOIS packet. It send corrupted WHOIS packet and
2212 caused problem with router to router connections. Affected
2213 file silcd/command.c.
2215 Fixed also silc_server_command_whois_check the same way
2216 as for the IDENTIFY command.
2218 * Added new SilcIDListStatus to the server in the SilcIDListData
2219 structure. The status now includes the current status of
2220 the entry (like registered, resolved etc.). Affected file
2221 silcd/idlist.[ch]. Defined a bunch of different status types
2222 as well. This replaced the old boolean registered field as well.
2224 Added resolve_cmd_ident field to the SilcClientEntry structure
2225 too so that if the entry is for example being resolved so
2226 another command may attach to the same pending command reply
2227 without requiring to resolve the same entry again. This concept
2228 should optimize the WHOIS and the IDENTIFY resolving under
2229 heavy load by taking away unnecessary resolving for entries
2230 that are being resolved already.
2232 Added support for adding multiple pending commands for one
2233 command idenfier. Affected file silcd/command[_reply].[ch].
2235 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2236 before deleting the data. Otherwise the hash table will have
2237 freed data in comparison functions. Affected file is
2238 silcd/command_reply.c.
2240 * Fixed silc_idlist_replace_client_id to add the new entry to
2241 the cache with NULL nickname. Otherwise there will be invalid
2242 memory as the nickname after the nickname is freed. Affected
2243 file silcd/packet_receive.c.
2245 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2246 saved into wrong slots because the previous number of entries
2247 was not taken into account. Affected file silcd/idlist.c.
2248 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2250 * If we are router and we receive JOIN notify to a channel that
2251 does not have any users then notified client is marked as the
2252 channel founder, as it is it. The affected file is
2253 silcd/packet_receive.c
2255 * Added to the extended hash table API's table_del_*ext functions
2256 the destructor as argument too, so that the caller can decide
2257 which destructor to use or whether to use destructor at all.
2258 Affected file lib/silcutil/silchashtable.[ch].
2260 * Fixed ID Cache purging. It actually deleted the entries from
2261 the hash table after the data was freed. The hash table ended
2262 up comparing freed memory. The affected file is
2263 lib/silccore/silcidcache.c.
2265 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Fixed Irssi SILC client's KILL command's HELP syntax.
2269 * The USERS command now resolves the detailed user information
2270 if the userinfo field is missing. Affected file is
2271 lib/silcclient/command_reply.c.
2273 * Do not print error in silc_file_read if the read file does
2274 not exist. Just silently return NULL. Affected file is
2275 lib/silcutil/silcutil.c.
2277 * Fixed the silc_log_output to not wine about NULL filename
2278 and to not create some bogus " " filename. Affected file is
2279 lib/silcutil/silclog.c.
2281 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Fixed various printing bugs on the user interface in the
2284 Irssi SILC Client. Minor changes that were forgotten from
2287 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Fixed the configure.in.pre and the compilation and distribution
2290 environment to support the new autoconf 2.52. That version is
2291 now required to compile the CVS trunk.
2293 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2296 to generally parse user@fqdn format strings. Affected file
2297 lib/silcutil/silcutil.c.
2299 * Added nickname_format and nickname_force_format fields to the
2300 SilcClientParams structure. The first one defines the format
2301 for the nicknames that the library will enforce if the receives
2302 multiple same nicknames. The second one is boolean value and
2303 can be used to force the library to always enforce the format
2304 to the nicknames regardles whether there are multiple nicknames
2305 or not. This configurable formatting was employed to flexibly
2306 support accessing multiple nicknames from the user interface.
2307 The userinterface can now set the nicknames to what ever format
2308 they prefer. Affected file lib/silcclient/silcapi.h.
2310 Added function silc_client_nickname_format to the file
2311 lib/silcclient/idlist.c. It performs the nickname formatting.
2313 Added new field `hostname´ to the SilcClientEntry context.
2314 It holds the hostname of the client. Affected file is
2315 lib/silcclient/idlist.h.
2317 * Irssi SILC Client sets the nicknames in nick@hostn format.
2318 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2319 irssi/src/silc/core/silc-core.c.
2321 The WHOIS printing now also shows both the real nickname and
2322 the formatted nickname so that user knows how to access the
2323 user if there are multiple same nicknames cached. Affected
2324 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2325 printing formatting too to take the hostname now as a separate
2326 argument. The Affected file is
2327 irssi/src/fe-common/silc/modules-formats.[ch].
2329 * Changed the silc_client_get_clients_local to accept the formatted
2330 nickname as argument. It accepts the real nickname too but the
2331 formatted nickname can be used to find the true entry from
2332 multiple entries. Affected file lib/silcclient/silcapi.h and
2333 lib/silcclient/idlist.c.
2335 * Added nickname_format_parse field to the SilcClientParams.
2336 It is a callback function provided by the application to parse
2337 the nickname out of the formatted nickname string. The library
2338 calls it to get the nickname from the formatted string. Since
2339 the application generally knows better the format of the nickname
2340 string it parses it instead of the library, even though library
2341 encodes the formatted string. If the callback function is not
2342 provided then the library will use the string as is. The
2343 affected file is lib/silcclient/silcapi.h.
2345 * All the nickname strings passed to the client library in
2346 commands are now expected to be formatted nickname strings.
2347 If the command does not support the formatted nickname string
2348 it will assume that the sent string is the actual nickname.
2349 Affected file lib/silcclient/command.c.
2351 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Added public key authentication support to OPER and SILCOPER
2354 commands in the client library. Affected file is
2355 lib/silcclient/command.c.
2357 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Changed the get_auth_methdod client operation to be asynchronous.
2360 It can be async if the application resolves the authentication
2361 method from the server during the negotiation. Added new
2362 SilcGetAuthMeth completion callback that the application will
2363 call after resolving the authentication method.
2365 Added function silc_client_request_authentication_method that
2366 the application can use to resolve the authentication method
2367 from the server. Added also SilcConnectionAuthRequest callback
2368 that the library will call after the server has replied. The
2369 application can call this function if it does not know the
2370 current authentication method.
2372 Affected files are lib/silcclient/client.c and
2373 lib/silcclient/silcapi.h.
2375 * The Irssi SILC client now automatically resolves the authentication
2376 method incase any configuration information is not present (and
2377 currently there never is). The affected file is
2378 irssi/src/silc/core/client_ops.c.
2380 * Fixed public key authentication from the client library.
2381 Affected file lib/silcclient/protocol.c. Changed also the
2382 protocol specification about the public key authentication in
2383 the connection authentication protocol. The actual data to be
2384 signed is now computed with a hash function before signing.
2386 * Fixed the public key authentication from the server as well.
2387 Affected file silcd/protocol.c.
2389 * Removed the mlock()'s from the memory allocation routines.
2390 Affected file lib/silcutil/silcmemory.c. The ./configure does
2391 not check anymore for the mlock(). Affected file is
2394 * Fixed USERS command in server to allow the execution of the
2395 command for private and secret channels if the client sending
2396 the command is on the channel. Affected file silcd/command.c.
2398 * Fixed silc_client_get_clients_local to return the clients
2399 count correctly. It could return wrong value. Affected file
2400 lib/silcclient/idlist.c.
2402 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2405 types. The assembler optimizations seemed not to like 64-bit
2406 data types. The assmebler optimizations thus are now enabled
2407 also for BSD systems as opposed to only enable them for Linux.
2409 * Do not check for threads at all on BSD systems. Affected
2410 file configure.in.pre.
2412 * Removed -n and -h options from the Irssi SILC Client since
2413 they are not used in silc.
2415 * Fixed the prime generation to assure that the first digit
2416 of the generated random number is not zero since our conversion
2417 routines does not like number strings that starts with zero
2418 digit. If zero digit is seen the random number is regenerated.
2419 This caused some corrupted RSA keys when the zero first digit
2420 was met. Affected file lib/silcmath/silcprimegen.c.
2422 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Fixed WIN32 configuration in the ./configure script.
2425 Fixed to include xti.h on environments that has it.
2426 Patches by Carsten Ilchmann and andrew.
2428 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Changed the silc_id_create_client_id to be collision
2431 resistant. It is now assured that there cannot be created
2432 two same client ID's. I suspect that some weird bugs in
2433 the server were actually caused by duplicate Client IDs.
2434 Affected file silcd/serverid.[ch]. A router receiving
2435 new ID now also assures and informs the sending server
2436 if the ID caused collision.
2438 * Changed the silc_id_create_channel_id to also assure that
2439 there are no collisions.
2441 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Statement about ignoring the Mutual Authentication flag when
2444 performing rekey with PFS was a bit misleading. It is ignored
2445 if it was set in the initial negotiation, it cannot be even
2446 set in the rekey. Fixed in the ke-auth draft. Started the
2447 new versions of the protocol drafts in the doc/.
2449 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Fixed a bug in silc_client_command_identify_save when saving
2452 new channel information. The channel name was no duplicated
2453 and caused crash on exit. Affected file is
2454 lib/silcclient/command_reply.c.
2456 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Fixed the getkey command handling in the server. Send just
2459 empty OK reply to the sender if the key could not be fetched
2460 (but everything else was ok, like the key just was not available).
2461 Changed the public key parameter to optional in the protocol
2462 specs so that empty OK reply can be sent. Affected file
2465 Added a message to Irssi SILC client to tell to user if the
2466 server did not return a public key.
2468 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed a channel key regeneration bug. It registered new
2471 timeout tasks exponentially until all system resources were
2472 used. Affected file silcd/server.c.
2474 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Added the SILC Document generator to the scripts/silcdoc.
2477 It can be used to generate the Toolkit Reference Manual out
2478 of the source tree. Internally it will also use the RoboDoc
2479 generator now imported in util/robodoc.
2481 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Added couple of return's in rekey protocol if error orccurred
2484 during the protocol. The execution must be terminated.
2485 Affected file silcd/protocol.c. Also, terminate the protocol
2486 always with timeout.
2488 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * The client's Client ID was created initally from the wrong
2491 nickname (it could have been in format nick@host) in the
2492 silc_server_new_client. Affected file silcd/packet_receive.c
2494 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Added some SILC_LOG_ERROR's to various error conditions
2497 if client could not be added to ID cache. Affected files
2498 silcd/packet_receive.c and silcd/server.c.
2500 * When client's sock->user_data is freed, NULL also the
2501 client->router and client->connection pointers. Added check
2502 for these pointers being NULL to various places around the
2503 code. Affected file silcd/server.c.
2505 * Added client->data.registered == TRUE checks to various
2506 places around the code to assure that unregistered client's
2507 are not handled when it is not allowed. Affected file
2510 * Added `bool registered' fields to all
2511 silc_idlist_[server|client]_get_* routines to indicate whether
2512 the fetched client needs to be registered or not. Affected
2513 file silcd/idlist.[ch].
2515 * Add your own entry as registered to the ID cache in the
2516 server. Affected file server.c.
2518 * Fixed a bug in silc_server_new_server. The SilcServer was
2519 set as the new server's context instead of SilcServerEntry.
2520 This naturally caused some weird bugs.
2522 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Do not delete the channel rekey task when adding it
2525 for in silc_server_create_channel_key.
2527 * Changed the silc_server_create_channel_key to return
2528 TRUE or FALSE to indicate the success of the channel key
2531 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Fixed MSVC++ project files and added missing files to
2534 Makefiles under win32/.
2536 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Do not add TCP_NODELAY flag if the operating system
2539 does not have it defined. Affected files are
2540 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2542 * Fixed buffer overflow from Irssi SILC Client. Affected
2543 file irssi/src/fe-common/core/themes.c.
2545 * Fixed double free in client library in the file
2546 lib/silcclient/client.c when disconnecting from server.
2548 * Applied double free patch from cras to Irssi SILC client.
2549 Affected files irssi/src/core/[modules/expandos].c
2551 * Fixed the disconnection handling to Irssi SILC Client.
2552 The application must call silc_client_close_connection
2553 in ops->connect client operation in case of failure of
2554 the connection. Affected file is
2555 irssi/src/silc/core/client_ops.c.
2557 * Do not set sock->protocol to NULL in the function
2558 silc_client_close_connection after executing the protocol's
2559 final callback since the sock might not be valid anymore.
2560 Affected file lib/silcclient/client.c.
2562 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Do not enable SILC_THREADS if the linking with libpthread
2565 did not happen. Affected file configure.in.pre.
2567 * Added notion to protocol specification that server must
2568 verify the sent authentication payload with CMODE when
2569 setting the channel founder key. Implemented it to the
2570 server. Affected file silcd/command.c.
2572 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Added _EXTRA_DIST SILC distribution variable to the
2575 distributions file. It is used to conditionally add extra
2576 files or directories to the specific distribution. Affected
2577 files ./prepare, Makefile.am.pre and distributions.
2579 Removed the `_' from the start of the distribution names.
2582 * Added README.WIN32 for instructions to compile the Toolkit
2585 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Fixed a double free in disconnection in the server. Affected
2588 file is silcd/server.c.
2590 * Fixed the lib/silcske/groups.c to work now also with GMP
2591 MP library. The string conversion did not work when using
2592 specific base and the base is indicated in the string as well.
2594 * Created win32/ directory which now includes MSVC++ specific
2595 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2596 It will appear only in the toolkit distribution
2598 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Changed the key material distribution function in case when
2601 the hash output is too short. The data is now concatenated
2602 a bit differently than it used to. Made the change to the
2603 SKE protocol specification.
2605 * Added better GMP detection to configure.in.pre. A patch
2608 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Fixed a minor bug in SKE that might cause some problem on
2611 some platforms. Affected file lib/silcske/silcske.c.
2613 * Added the cookie checking for initiator in the SKE. It checks
2614 that the responder returns the sent cookie unmodified. The
2615 affected file is lib/silcske/silcske.c. Added new SKE
2616 error type INVALID_COOKIE that can be sent during the
2617 negotiation. Fixed some memory leaks as well.
2619 * Added the "invalid cookie" error message to Irssi SILC client's
2622 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Added `task_max' field to the SilcClientParams to indicate
2625 the maximum tasks the scheduler can handle. If set to zero,
2626 default values are used. Affected file lib/silcclient/silcapi.h.
2628 * Fixed memory leaks in silc_client_close_connection. Affected
2629 file lib/silcclient/client.c.
2631 * Added silc_client_del_client_entry to client library to free
2632 all memory of given client entry. Affected file is
2633 lib/silcclient/idlist.[ch].
2635 * Added new functions silc_client_del_channel and
2636 silc_client_del_server to delete channel and server entries.
2637 Affected file lib/silcclient/[silcapi.h/idlist.c].
2639 * Removed silc_client_del_client_by_id from silcapi.h.
2641 * Fixed the INFO command to return the server's own info
2642 correctly when querying by Server ID. Affected file is
2645 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Removed the non-blocking settings in WIN32 code in the
2648 silc_sock_[read/write] and added SleepEx instead. Affected
2649 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2650 of input data is now checked with FIONREAD and ioctlsocket.
2652 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Call silc_schedule_task_del_by_context in the
2655 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2656 Affected file lib/silccore/silcprotocol.c.
2658 * Call silc_protocol_cancel for active protocols in the
2659 silc_server_close_connection if the funtion
2660 silc_server_free_sock_user_data has not been called.
2661 Affected file silcd/server.c.
2663 * Generic tasks cannot be deleted using the del_by_fd
2664 task deleting function since generic tasks does not match
2665 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2667 * Added a notion to SILCOPER help file that the SILCOPER works
2668 only on router server, not on normal server.
2670 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Added for WIN32 support for the new scheduler as well.
2673 Affected file lib/silcutil/win32/silcwin32schedule.c.
2675 * Fixed the SHA1 implementation to work on various platforms.
2677 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2680 API. It is part of the scheduler now. Everything else is
2681 as previously but some functions has changed their names.
2682 Checkout the lib/silcutil/silcschedule.h for the interface.
2683 Updated all applications to use the new interface. Affected
2684 files are lib/silcutil/silcschedule.[ch].
2686 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Found a bug in the SKE implementation. The HASH value,
2689 specified by the protocol, was not computed correctly. The
2690 public key of the responder was not added to the computation
2691 even though it is mandatory. Affected file lib/silcske/silcske.c.
2692 This unfortunately causes incompatibilities with older
2693 clients and servers.
2695 * Added WIN32 specific network init and uninit functions:
2696 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2697 the Winsock2. Affected file lib/silcutil/silcnet.h and
2698 lib/silcutil/win32/silcwin32net.c.
2700 * Set the socket always to nonblocking mode on WIN32 after
2701 reading data or writing data. Affected file is
2702 lib/silcutil/win32/silcwin32sockconn.c.
2704 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Fixed various compilation problems under WIN32. Affected
2707 files lib/silcutil/win32/silcwin32thread.c and
2708 lib/silcutil/win32/silcwin32schedule.c.
2710 * Removed all _internal.h #includes from public header
2711 files. Internal headers must never be included from
2714 Removed also the lib/silcske/payload_internal.h file.
2716 * All include files that may be needed (public and some others
2717 included by the public headers) by application developers are
2718 now copied to the ./includes directory. It does not copy any
2719 internal headers. Affected file Makefile.defines.pre and all
2720 Makefile.am's under lib/ and subdirs.
2722 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Do not change the ~/.silc directory's permissions automatically.
2725 Affected file irssi/src/silc/core/clientutil.c.
2727 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Do not cancel the protocol in silc_server_close_connection
2730 it might cause recursion. Now cancelled in the function
2731 silc_server_free_sock_user_data. Affected file silcd/server.c.
2733 * Fixed the silc_server_remove_clients_by_server to regenerate
2734 the channel keys correctly finally. Added also new function
2735 silc_server_remove_clients_channels to actually do it.
2736 Affected file silcd/server.c.
2738 * Fixed the silc_server_new_channel to not crash by giving
2739 wrong router to the new channel. Affected file is
2740 silcd/packet_receive.c.
2742 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2745 which is given as argument to the silc_client_alloc now.
2746 It can be used to configure the client and set various parameters
2747 that affect the function of the client.
2749 * The USERS command in server did not check whether the channel
2750 is private or secret. Affected file silcd/command.c.
2752 * Added new argument to the USERS command in protocol specification.
2753 The USERS command now can take the channel name as argument
2754 as well. Added support for this in client and server and
2755 updated the protocol specs.
2757 * Completed the GETKEY command in client. It can be now used
2758 to fetch also servers public key not only some clients.
2759 Affected files lib/silcclient/command[_reply].c.
2761 * Added silc_client_get_server to return server entry by the
2762 server name. Affected files lib/silcclient/silcapi.h and
2765 * Redefined the IDENTIFY command in protocol specification to be
2766 more generic. It now can be used to query information about
2767 any entity in the SILC Network, including clients, servers and
2768 channels. The query may be based either the entity's name
2769 or the ID. Added support for this in both client and server.
2771 Affected files silcd/command.c and lib/silcclient/command.c
2772 and command_reply.c.
2774 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2775 the _from_client and _from_server functions. Affected file
2778 * Added silc_client_get_channel_by_id_resolve to the file
2779 lib/silcclient/silcapi.h to resolve channel information by
2780 its ID. Added also silc_client_get_channel_by_id that
2781 does not resolve it from the server.
2783 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Added SilcServerEntry context into the client library
2786 to represent one server. The INFO command now allocates
2787 these to save the resolved server info. For now on the
2788 client library will also keep information about servers,
2789 connected and resolved with INFO.
2791 The INFO command now allocates the SilcServerEntry context
2792 and saves the server info there. The COMMAND_REPLY in
2793 the INFO now returns the parameters to application in
2794 same order as defined in the protocol specification.
2796 The entries are cached in the client->server_cache.
2798 * The INFO command is now issued after received the Client ID
2799 from the server. Affected file lib/silcclient/client.c.
2801 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2802 to the application as the mode changer might be server.
2803 It is guaranteed that NULL is not returned anymore to the
2804 application. Affected file lib/silcclient/client_notify.c.
2806 The ID Type is now also passed to the application so that
2807 it can check whether the returned entry is SilcClientEntry
2810 Added new function silc_client_get_server_by_id to return
2811 the server entry by ID. Affected files are the
2812 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2814 * Do not create the channel in the Irssi SILC Client when issuing
2815 the JOIN command but when received the sucessful JOIN command
2816 reply. Otherwise the channel might get created even though we
2817 could not join it. The Affected file is
2818 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2820 * Fixed a channel joining bug in router. The router must also
2821 check the channel modes, invite and ban lists etc. when serving
2822 the JOIN command sent by normal server. Affected file is
2823 silcd/command.c. The router now resolves the client's
2824 information from the server who sent the JOIN command if it
2825 does not know it, and processes the JOIN command only after
2828 * Changed the SilcCommandCb to take new argument; void *context2.
2829 Affected file lib/silccore/silccommand.h
2831 The second argument in the command callbacks in the server now
2832 includes the SilcServerCommandReplyContext if the command was
2833 called as pending command callback from the command reply.
2834 Otherwise it is NULL. When called as pending the status of the
2835 command reply will be checked and if it was erronous the
2836 error will be sent to the original sender of the command.
2837 This way the client always receives the error messages even
2838 though the server was actually the one who received the error
2839 when it resent the command to router, for example. Affected
2840 files silcd/command[_reply].[ch].
2842 * Fixed sending WHOWAS command's error message to client if
2843 the requested client could not be found. It was missing.
2846 * Changed the CMODE and CUMODE commands reply arguments in the
2847 protocol specification. The Channel ID is now sent in both
2848 of the commands to identify the channel. Implemented this
2849 new feature to the client and server. Affected files
2850 lib/silcclient/command_reply.c and silcd/command.c.
2852 * Made better checks for invite and ban lists in the JOIN
2853 command in server. Affected file silcd/command.c.
2855 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * The server now performs the incoming host IP/DNS lookup
2858 using the silc_socket_host_lookup and thus does not block
2859 the server anymore. Affected file silcd/server.c.
2861 * Completed the multi-thread support for SILC Scheduler in
2862 the lib/silcutil/silcschedule.c.
2864 * Fixed the configure.in.pre to detect the pthread correctly
2867 * Fixed a deadlock in silc_task_queue_wakeup in the file
2868 lib/silcutil/silctask.c.
2870 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Added new function silc_schedule_wakeup that is used in
2873 multi-threaded environment to wakeup the main thread's
2874 schduler. It needs to be used when a thread adds a new task
2875 or removes a task from task queues. After waking up, the
2876 scheduler will detect the task queue changes. If threads
2877 support is not compiled in this function has no effect.
2878 Implemented the wakeup mechanism to both Unix and WIN32
2879 systems. Affected files are lib/silcutil/silcschedule.[ch],
2880 lib/silcutil/unix/silcunixschedule.c and the
2881 lib/silcutil/win32/silcwin32schedule.c.
2883 * Added new function silc_task_queue_wakeup to wakeup the
2884 scheduler by the specified task queue. Affected file
2885 lib/silcutil/silctask.[ch].
2887 * The silc_socket_host_lookup_start now wakes up the scheduler
2888 after adding the timeout task. Affected file is
2889 lib/silcutil/silcsockconn.c.
2891 * The silc_socket_host_lookup is synchronous now if the threads
2892 support is not compiled in. However, the callback is still
2893 called asyncronously through the scheduler, anyway. Affected
2894 file lib/silcutil/silcsockconn.c.
2896 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Added new function silc_socket_host_lookup to perform
2899 asynchronous IP and FQDN lookups for the socket connection.
2900 Affected files lib/silcutil/silcsockconn.[ch].
2902 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2905 that may or may not compile the mutex support in.
2907 Changed the silc_mutex_alloc interface. It allocates the
2908 mutex now to the sent pointer and returns TRUE or FALSE.
2910 Affected file lib/silcutil/silcmutex.h.
2912 * Wrote the SILC Task Queue interface to support multi-threads.
2913 Affected file lib/silcutil/silctask.[ch].
2915 * Wrote the SILC Scheduler to support multi-threads. Affected
2916 file lib/silcutil/silcschedule.c.
2918 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2921 in lib/silcutil/win32/.
2923 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Defined SILC Mutex API and SILC Thread API and implemented
2926 them for Unix. Affected files are
2927 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2928 lib/silcutil/unix/silcunixmutex.c and
2929 lib/silcutil/unix/silcunixthread.c.
2931 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Fixed the silc_server_remove_clients_by_server's channel
2934 key re-generation. The hash table handling was incorrect
2935 and would not work with many channels. Affected file is
2938 * Fixed some memory leaks around the server code.
2940 * Rewrote the silc_server_get_users_on_channel to support IPv6
2941 based Client ID's. Affected file silcd/server.c.
2943 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2944 specification. However, a separate document must be written
2945 to define the detailed signing procedure and the payload
2946 associated with the flag. Defined the flag to the
2947 lib/silccore/silcchannel.h as well.
2949 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Changed the dynamic tables to static size tables in the
2952 lib/silccrypt/silchmac.c.
2954 * Removed GCC dependencies from the code. A patch by cras.
2956 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Do not show the error "Error receiving packet bla bla"
2959 in server if it really was not an error (-2 means that reading
2960 is pending). Affected file silcd/server.c.
2962 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Fixed a possible crash in silc_server_remove_clients_by_server
2965 in silcd/server.c. Fixed there also some memory leaks.
2967 * Fixed the silc_idlist_replace_client_id. It could replace
2968 wrong key in the hash table. Affected file silcd/idlist.c.
2970 * Do not check whether there are global users on the channel
2971 if the channel->global_users is FALSE. Affected functions
2972 silc_server_remove_from_one_channel and
2973 silc_server_remove_from_channels in silcd/server.c. Also,
2974 do not check if the removed client is local as we can be
2975 sure that global client was not removed from the channel
2976 and checking for global users is not needed.
2978 * The silc_server_remove_clients_by_server now re-generates
2979 the channel keys correctly for those channels that had
2980 clients removed from them. Affected file silcd/server.c.
2982 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Found the reason of random crashes in the server. We weren't
2985 ignoring the SIGPIPE signal (which can be sent in write())
2986 and it crashed the server. Affected file silcd/silcd.c.
2988 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Assure that sock->user_data is not NULL in the function
2991 silc_server_packet_send in silcd/packet_send.c.
2993 * Disconnect the remote connection if it could not be added
2994 to any ID lists in the server. The affected file is
2997 * Check in silc_server_packet_send[_real/dest] that the
2998 socket is not disconnecting and ignore the data if it is.
2999 Affected file silcd/packet_send.c.
3001 * Define inline to __inline on native WIN32 compilation.
3002 Affected file includes/silcwin32.h.
3004 * Added some explicit type casts for inline code since MSVC
3005 require them. Affected files lib/silcutil/silcbuffer.h,
3006 lib/trq/silcdlist.h and lib/trq/silclist.h.
3008 * Print warning in log files from now on if the packet
3009 decryption fails. Affected file silcd/server.c.
3011 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Changed the `say' client operation's interface to accept
3014 new `type' argument to indicate the type of the message sent
3015 by the library. The application may filter the library's
3016 messages according the type. The affected file is the
3017 lib/silcclient/silcapi.h.
3019 * Added two new functions to lib/silcclient/silcapi.h:
3020 silc_client_del_client and silc_client_del_client_by_id.
3021 Affected file lib/silcclient/idlist.c.
3023 * Moved the clientincludes.h from includes/ to silc/ and
3024 serverincludes.h from includes/ to silcd/.
3026 * The modes for the CMODE and CUMODE are now passed as
3027 uint32 for application with COMMAND_REPLY. The affected
3028 file is lib/silcclient/command_reply.c.
3030 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * /WHOIS without arguments shows client's own information.
3033 Affected file lib/silcclient/command.c.
3035 * Changed PING to not accept any arguments. The specs
3036 says that client can ping only the connected server so
3037 requiring an argument is not needed. Affected file is
3038 lib/silcclient/command.c.
3040 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Fixed a fatal bug in private message sending and reception
3043 encryption and decryption when using private message keys.
3044 The implementation was incorrect and did not follow the
3045 specification. It causd that some of the message were
3046 lost since it did not use the sending and receiving keys
3047 as the protocol suggests. This has been fixed and will cause
3048 incompatibilities with older clients when sending private
3049 message encrypted with private message keys. Affected files
3050 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3051 and various other in Irssi SILC Client.
3053 Added `responder' boolean argument to the functions
3054 silc_client_add_private_message_key[_ske] to indicate when
3055 the key is added as responder or initiator of the key
3058 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Removed the silc_ske_check_version function and created
3061 a SilcSKECheckVersion callback. Added also a function
3062 silc_ske_set_callbacks that is now used to set all SKE
3063 callbacks. The callback functions are not given to
3064 the SKE functions anymore, but this function is used to
3067 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3069 * Added `silc_version' argument to the silc_client_alloc
3070 to define the version of the application for the library.
3071 The library will use the version string to compare it
3072 against the remote host's (usually a server) version
3073 string. Affected file lib/silcclient/silcapi.h
3075 * Added the KE protocol context to Key Agreement context
3076 in client library so that we can abort the SKE if it
3077 is in process when we get timeout. Affected file is
3078 lib/silcclient/client_keyagr.c.
3080 * Do not resolve the client ID forever if it returns in the
3081 first time that such client does not exist. This was done
3082 for example with private message. Affected file is
3083 lib/silcclient/client_prvmsg.c.
3085 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Do not add regex.h for WIN32. The affected file
3088 includes/silcincludes.h.
3090 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3091 not work yet 100%. It generates the DLL's automatically
3092 when compiling with --with-win32 under cygwin.
3094 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * lib/contrib/regex.c is not compiled on WIN32.
3098 * Added silc_net_get_socket_opt function to the
3099 lib/silcutil/silcnet.h.
3101 * Added includes/silcwin32.h for WIN32 specific includes
3104 * Do not use ptime structure or any of the posix process
3105 functions on WIN32 in lib/silccrypt/silrng.c.
3107 * Added silc_gettimeofday to provide generic function
3108 for struct timeval on all platforms. Added the function
3109 to lib/silcutil/silcutil.h.
3111 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3114 library as they clearly belong there. As a plus side we
3115 can make the actual socket connection routines platform
3118 Added also new generic function silc_socket_read and
3119 silc_socket_write (that used to be silc_packet_[read/write].
3120 The implementation of these are platform specific.
3122 * Added WIN32 specific routines of silc_socket_[read/write]
3123 to lib/silcutil/win32/silcwin32sockconn.c.
3125 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Added preliminary support for native WIN32 compilation under
3128 cygwin (using the -mno-cygwin option for GCC) to the
3129 ./configure.in.pre. The --with-win32 now prepares the
3130 compilation for native WIN32.
3132 * Rewrote the SILC Scheduler interface in the file
3133 lib/silcutil/silcschedule.h. The scheduler is now context
3134 based and does not have anymore any global static scheduler.
3135 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3136 and created lib/silcutil/win32 directory for WIN32 based
3139 * Added Unix specific network routines to the
3140 lib/silcutil/unix/silcunixnet.c and the old
3141 lib/silcutil/silcnet.c includes now only generic routines.
3143 Added WIN32 specific network routines to the
3144 lib/silcutil/win32/silcwin32net.c.
3146 * Added Unix specific utility functions from the
3147 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3149 * Added WIN32 SILC Scheduler to the file
3150 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3153 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Do not handle JOIN notify in the server if the target client
3156 is not registered (idata->registered == FALSE). The affected
3157 file is silcd/packet_receive.c.
3159 * Update the nickrec->founder in event_cumode in the Irssi SILC
3160 client. Affected file irssi/src/silc/core/silc-channels.c.
3162 * Fixed the CUMODE_CHANGE notify handling in the server when
3163 server and router are announcing their clients on channels.
3164 Now the mode changes are saved and notified correctly. The
3165 affected file is /silcd/packet_receive.c.
3167 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3168 They really did not replace the cache entry in the ID Cache.
3169 Now they do that. Affected file silcd/idlist.c.
3171 * Fixed the KICK notify handling in the Irssi SILC client to
3172 update the channel records so that the kicked client does not
3173 appear to be on the channel. The affected file is
3174 irssi/src/silc/core/silc-channels.c.
3176 * Always update the conn->current_channel when executing command
3177 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3179 * Fixed the KILL notify handling in Irssi SILC client to remove
3180 the killed client on all channels.
3182 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Fixed the silc_parse_command_line to remove extra spaces
3185 from the start and end of the arguments. Affected file is
3186 lib/silcutil/silcutil.c.
3188 * Cancel and free any active protocol in the function
3189 silc_server_close_connection. Affected file silcd/server.c.
3191 * Cancel and free any active protocol in the function
3192 silc_client_close_connction. Affected file is
3193 lib/silcclient/client.c.
3195 * Do not execute the KILL command for clients that are in
3196 history (ie. they are not in the network). Affected file is
3199 * Fixed KILL notify handling, client does not crash anymore.
3200 Affected file irssi/src/silc/core/silc-channels.c.
3202 * Reduced the default packet buffer size from 2048 to 1024 in
3203 lib/silccore/silcpacket.c.
3205 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3206 counter to the SKE context that is incresed when the SKE library
3207 performs async operation outside the library. If the outside
3208 process frees the SKE context and FREED status will be set
3209 and the library will detect after the sync operation that the
3210 libary is freed. The affected files are
3211 lib/silcske/silcske[_status].[ch].
3213 * Resolve the client entry information in the function
3214 silc_client_channel_message to assure that NULL pointer is not
3215 passed as client entry to the application. */
3217 * Fixed the task timeout calculation to assure that there is
3218 never negative timeouts. The affected file is
3219 lib/silcutil/silcschedule.c.
3221 * Fixed the channel user mode notification sending in server.
3222 It was sent point-to-point to the router (or to server by router)
3223 but it needs to be destined to a channel. The routines now
3224 supports sending the channel user mode notifys to the channels
3225 when announcing clients and channels. Affected files are
3226 silcd/server.c and silcd/packet_receive.c.
3228 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3229 It did not actually replace the old channel entry in the cache.
3230 Affected file lib/silcclient/client_notify.c.
3232 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Fixed a possible crash in silc_packet_send_prepare. It now
3235 assures always that there is enough space in the buffer and
3236 at the tail area of the buffer (for MAC).
3238 Fixed the inbound buffer reallocation in silc_packet_read.
3239 It was old code and did not handle the reallocation correctly.
3242 The affected file is lib/silccore/silcpacket.c.
3244 * Fixed buffer overflow in silc_parse_nickname in the file
3245 lib/silcutil/silcutil.c.
3247 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * make install generates new server keys only if there is not
3252 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3255 Added check that if the NOREPLY is set then we will not send
3256 the away message. This avoids infinite loop of away messages
3257 if both clients are away. The affected file is
3258 lib/silcclient/client_prvmsg.c.
3260 * Fixed client crash if /NICK was given without arguments.
3261 Affected file lib/silcclient/command.c.
3263 * Server does not send the invite list in INVITE command back
3264 to the client if the list was not altered. Added this notion
3265 to the protocol spec as well. Affected file silcd/command.c.
3267 Fixed possible crash in INVITE command by checking the
3268 value of silc_server_get_client_route command.
3270 * Fixed the INVITE notify type handling. The arguments are now
3271 taken in correct order and client does not crash. The affected
3272 file is irssi/src/silc/core/silc-channels.c.
3274 Removed the "Inviting xxx to channel" message from the
3275 client library away and let the application handle it.
3276 Affected file lib/silcclient/command.c. Added that message
3277 to Irssi SILC client's message formats.
3279 * Fixed CMODE command crash in client. It now checks the
3280 amount of arguments correctly and does not crash. The affected
3281 file is lib/silcclient/command.c.
3283 * Do not create new channel automatically in silc_channels_join
3284 but check whether the channel by that name already exists.
3285 Affected file irssi/silc/core/silc-channels.c.
3287 * Do not send the SERVER_SIGNOFF to router if the disconnected
3288 entity was the router. Affected file silcd/server.c.
3290 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3291 SILC client as it was missing from there.
3293 Added the handling of the KICK notify to the Irssi SILC client
3294 as it was missing. Added "you have been kicked" message to
3295 Irssi SILC client's message modules formats.
3297 Added the handing of the KILL notify to the Irssi SILC client
3298 as it was missing. Added the kill message module formats
3301 The affected file is irssi/src/silc/core/silc-channels.c.
3303 * The router did not save the channel mode the server announced.
3304 Affected file silcd/packet_receive.c.
3306 * Fixed a possible crash in INFO command in server. If the
3307 server did not provide the server info it crashed. Affected
3308 file silcd/command.c.
3310 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Fixed the GETKEY command in the server to check also the
3313 global list. Otherwise the GETKEY would not work correctly
3314 in normal SILC server. Affected file silcd/command.c.
3316 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Fixed GETKEY crash, it crashed if the command did not succseed.
3320 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3323 is now real and not just an macro interface to GMP.
3325 Removed the entire GMP from the source tree and imported new
3326 NSS MPI library instead. Reason for removing GMP is that it is
3327 extremely large and compiles extremely slow. The NSS MPI
3328 is only a few files and compiles in less than 10 seconds.
3329 The speed is also about the same as GMP. The MPI is imported
3330 to lib/silcmath/mpi.
3332 If the system has GMP installed we will still use the GMP.
3333 If it is not then the NSS MPI will be compiled.
3335 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Merged a long nickname (127 characters long) crash bugfix from
3338 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3340 * Merged a freed memory reference bugfix from Irssi CVS tree.
3341 Affected file irssi/src/core/commands.c.
3343 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Added the server's public key sving and verification to the
3346 server when performing the SKE. This was missing and the
3347 remote server's (or router's) public key was accepted without
3348 checking whether we have it previously or trust it at all.
3349 Affected file silcd/protocol.c.
3351 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Check in the silc_server_timeout_remote if protocol is active
3354 and make sure that the protocol's final callback is called so
3355 that all memory if freed. Affected file silcd/server.c.
3357 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * silc_server_whois_send_reply crashed the server if the nickname
3360 was 127 characters long. Affected file silcd/command.c.
3362 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added sanity check to the silc_server_new_client. If the hostname
3365 is provided inside username then check that the provided hostname
3366 really is the same as the resolved one. If the hostname was not
3367 resolved then check it from the public key. Affected file is
3368 silcd/packet_receive.c.
3370 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3371 if the server disconnected us and the connection is not valid
3372 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3374 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3375 the library to the lib/silcutil/silcutil.[ch].
3377 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Close log file after open. Affected file
3380 lib/silcutil/silclog.c.
3382 * Check whether sock == NULL in silc_client_send_packet and return
3383 if it is. Affected file lib/silcclient/silcclient.c.
3385 * Check rec->entry == NULL in the Irssi SILC Client before
3386 sending the channel message. Affecte file is
3387 irssi/src/silc/core/silc-servers.c.
3389 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Merged a splitted window bugfix from Irssi CVS tree. The
3392 affected file is irssi/src/fe-text/textbuffer-view.c.
3394 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3395 It did not print nickname.
3397 * Improved the distributions system a bit.
3399 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3402 irssi/src/fe-text/gui-window.c.
3404 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3405 to in-active server. The affected file is
3406 irssi/src/silc/core/client_ops.c.
3408 * Resolve the client in USERS command reply if the entry does
3409 not have username resolved. The affected file is
3410 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3411 command to WHOIS command to really resolve stuff. The USERS
3412 is not used any more in any critical section so WHOIS can
3413 be used even though it might be slower than IDENTIFY.
3415 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3418 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Changed the protocol API a bit more consistent in the
3421 lib/silccore/silcprotocol.[ch].
3423 * Changed the following headers to ROBODoc format:
3425 lib/silccore/silcpayload.h
3426 lib/silccore/silcprotocol.h
3427 lib/silccore/silcsockconn.h
3429 All core library headers are now formatted.
3431 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Fixed a bug in Irssi SILC client; do not show that you are
3434 server/router operator if you really are not. Affected file is
3435 irssi/src/silc/core/client_ops.c.
3437 * Renamed silc_command_free_payload to silc_command_payload_free.
3438 Affected file lib/silccore/silccommand.h
3440 * Added silcmath.h to include the prototoypes of various routines
3441 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3444 * Changed the following headers to ROBODoc format:
3446 lib/silccore/silcchannel.h
3447 lib/silccore/silccommand.h
3448 lib/silccore/silcid.h
3449 lib/silccore/silcidcache.h
3450 lib/silccore/silcmode.h
3451 lib/silccore/silcnotify.h
3452 lib/silccore/silcpacket.h
3453 lib/silcmath/silcmath.h
3455 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added checking to the server code not to start the server if
3458 ciphers and stuff are not configured properly. Affected files
3459 silcd/serverconfig.[h] and silcd/server.c.
3461 * Changed the layout of the header files of the public interfaces
3462 in the SILC libraries. The new layout supports ROBODoc
3463 documentation tool (and some others) so that it is easy to create
3464 a library reference manual. All the other headers and source
3465 code must still follow the CodingStyle document. Also source
3466 code must not include these ROBODoc stuffs, only the headers.
3467 Furthermore, all public interface headers must now be named
3468 by using `silc' prefix, example: silcapi.h, silccipher.h.
3469 Some files were renamed due to this. All the other headers
3470 must not be used as public interfaces. I will update the
3471 CodingStyle document later. Changed following headers, so far:
3473 lib/silcclient/silcapi.h
3474 lib/silccore/silcauth.h
3475 lib/silccore/silcprivate.h
3476 lib/silccrypt/silcdh.h
3478 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Removed silc_client_packet_send_flush from the client library
3483 as it is not needed. Affected file lib/silcclient/client.[ch].
3485 * Added printing of message of unresolved authentication method
3486 to the Irssi SILC client. Added it to the module formats.
3487 Removed the same message from the client library.
3489 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Added new distribution feature, DISTLABEL. Every distribution
3492 can define own preprocessor label that can be used in the
3493 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3494 file distributions, acconfig.h.pre and prepare.
3496 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Added Makefile.defines_int to include the actual definitions
3499 for Makefile.defines.in. Tested the new distribution system,
3500 created distributions and tested installation.
3502 * Added AWAY message printing to the Irssi SILC client. Added
3503 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3505 * Added SCONNECT command to call the SILC's CONNECT command.
3506 Cannot use CONNECT directly since Irssi uses that internally.
3507 Affected file irssi/src/silc/core/silc-servers.c.
3509 Added ACTION local command. It is same as ME command but takes
3510 the channel as mandatory argument.
3512 Rewrote some of the Irssi's help files to suite for SILC
3515 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Added Makefile.defines[.in] that should for now on be included
3518 in all Makefile.am file in the source tree. That file includes
3519 all common compilation definitions for SILC source tree.
3521 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Minor changes to the ./prepare script to change the package
3524 name according the distribution name to the configure.in.
3526 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Created new distribution system. Added file `distributions'
3529 that defines all the distributions that can be created out of
3530 the SILC source tree. The ./prepare script now reads that
3531 file to determine how to prepare the distributions. The
3532 first argument to the ./prepare is the name of the distribution
3533 and second is the version of the distribution. If given
3534 without arguments it creates the default (toolkit) distribution
3535 with the default version (defined in ./prepare).
3537 All Makefile.am files that are subject to the distributions
3538 are now named as Makefile.am.pre. These are ./Makefile.am
3539 and lib/Makefile.am. Others may be changed later.
3541 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Added invite list, ban list, some key management and connection
3544 error message printing to module formats in the Irssi SILC client.
3546 * Added new silc_client_set_away_message to set the away message
3547 that is back to the person who sent private message. The
3548 affected file lib/silcclient/silcapi.h and the
3549 lib/silcclient/client_prvmsg.c.
3551 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Fixed the private message sending in the Irssi SILC client,
3554 added local command KEY to the Irssi SILC client.
3556 Added key management and key agreement message formats to the
3557 irssi/src/fe-common/silc/module-formats.[ch].
3559 Added USERS (alias WHO) printing, server/router operator
3560 indication and LIST command printing to the module formats.
3562 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Fixed channel joining notify handling, cumode notify handling
3565 from Irssi SILC client.
3567 * Added SILC specific module-formats to the Irssi SILC client so
3568 that SILC specific message hilighting, colors etc is possible.
3569 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3571 Added channel mode, channel user mode, actions, notices,
3572 whois and whowas printing to the the module-formats.c.
3574 * Fixed a bug in channel deletion in the server. The channel
3575 is not left to the cache even if the channel founder auth mode
3576 is set when there are no users anymore on the channel. Affected
3577 file silcd/server.c.
3579 * The silc_net_localhost now resolves the entire hostname including
3580 the domain name. Affected file lib/silcutil/silcnet.c.
3582 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Changed the ask_passphrase client operation to be ascynchronous.
3585 It has now a completion callback and a context that the
3586 application must call after it has got the passphrase from
3587 the user. Affected files lib/silcclient/silcapi.h,
3588 lib/silcclient/protocol.c, lib/silcclient/command.c and
3591 Added SilcAskPassphrase callback that the application calls
3592 to deliver the passphrase to the library.
3594 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3595 The public key verification and especially a certificate
3596 verification is asynchronous procedure.
3598 Added new SILC_SKE_STATUS_PENDING status to indicate the
3599 request is pending and a callback will be called to finalize
3602 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3603 indicate that remote end did not send its public key (or
3604 certificate), even though we require it. Added check for this
3605 condition in the SKE. This was a security bug, now fixed.
3607 Defined new SilcSKEVerifyCbCompletion callback that is called
3608 when the verification process is completed.
3610 The affected files lib/silcske/silcske_status.h and
3611 lib/silcske/silcske.[ch].
3613 * Changed the verify_public_key client operation to be async
3614 as well. Defined SilcVerifyPublicKey callback that is used to
3615 indicate the success of the public key verification process.
3617 Changed the server and client to use the new async client
3620 * Changed the Irssi SILC client's internal scheduler to be called
3621 twice as many times as it used to be. As a result the client
3622 should be a bit faster now. Affected file is
3623 irssi/src/silc/core/silc-core.c.
3625 * Added support to Irssi SILC client of asynchronous public key
3626 verification and passphrase inquiry. Affected file is
3627 irssi/src/silc/core/silc-core.c.
3629 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Do not say "You have left channel %s" in client library.
3632 Moved it to the application. Affected files are
3633 lib/silcclient/command.c and silc/client_ops.c.
3635 * Fixed silc_client_get_clients. Command context was not
3636 duplicated and was freed memory in the callback. Affected
3637 file lib/silcclient/idlist.c.
3639 * Do not say "you are now talking..." on JOIN command in the
3640 client library. The appliation must handle it.
3642 * Do not say ".. changed topic to" in command reply in the
3643 client libary. The application must handle it.
3645 * Fixed TOPIC command sending in the client library.
3647 * Fixed a memory leak in silc_client_command_free in the file
3648 lib/silcclient/command.c.
3650 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Imported a modified version of Irssi client to the source tree.
3653 The Irssi will be used to create a new client called
3654 Irssi SILC. Imported to irssi/.
3656 Added silc_core_init_finish function to the Irssi. Affected
3657 file irssi/configure.in.
3659 A lot changes in the Makefile.ams around the irssi tree.
3661 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Do not rehash if the new size is same as the old size of the
3664 hash table, in the silc_hash_table_rehash*. The affected file
3665 lib/silcutil/silchashtable.c.
3667 * Replaced hash_table_del_by_context calls from the server
3668 (when channel->user_list and client->channels) to the
3669 hash_table_del as it is sufficient and faster.
3671 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Added silc_hash_table_list, silc_hash_table_get and the
3674 SilcHashTableList structure to provide an alternative way to
3675 traverse the hash table. The affected files are
3676 lib/silcutil/silchashtable.[ch].
3678 * Changed the server's idlist routines to use the hash table
3679 routines to optimize the code.
3681 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Replaced the client entry's `channel' list and channel entry's
3684 `user_list' list to hash tables for optimized lookup. Changed
3685 the code to use the hash table interface around the code.
3686 Affected file lib/silcd/idlist.[ch].
3688 * Added `auto_rehash' boolean argument to the function
3689 silc_hash_table_alloc to indicate whether the hash table should
3690 auto-rehash when it thinks is appropriate time. It will
3691 increase the hash table size if the there is twice as much
3692 entries in the table than the size of the table, and will
3693 decrease the size if there are twice as less entries than
3694 the size of the table.
3696 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3700 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * silc_idcache_purge_by_context deletes the entry now by context
3703 as it is supposed to do. Affected file lib/silccore/idcache.c.
3705 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3706 client is not anymore valid (WHOWAS givens the info) and not
3707 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3709 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Removed the `data' and `data_len' arguments from the ID Cache
3712 interfaces and added `name' argument. ID Cache does not handle
3713 anymore the binary data only a names associated with given ID.
3715 * When hashing a Client ID with silc_hash_id the entire ID is
3716 not hashed anymore, instead only the hash of the Client ID is
3717 hashed. This way we can access the Client ID from the cache
3718 with Client ID but with the hash of the ID (which is a hash of
3719 the nickname) as well without any difference in performance.
3721 Added also silc_idcache_find_by_id_one_ext to do one on one
3722 searching when we have the actual ID. Added also function
3723 silc_hash_client_id_compare. The affected files are
3724 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3726 * When hashing the name associated with a ID it is always done
3727 in lowercase. This way we can access the cache without worrying
3728 about case-sensitivity, even though, for example nicknames are
3731 * Fixed a bug in server with channel message sending. It put
3732 wrong ID type as destination ID. The affected file
3733 silcd/packet_send.c.
3735 * silc_idcache_del_by_context now deletes from all hash tables
3736 by context. Affected file lib/silccore/idcache.c.
3738 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Changed the client library to use the new ID Cache interface.
3741 Changes around the source tree.
3743 * Added silc_hash_table_rehash_ext to rehash with specific
3744 hash function. Affected file lib/silcutil/silchashtable.[ch].
3746 * Added silc_hash_string_compare to compare two strings in the
3747 hash table. Affected file lib/silcutil/silcutil.[ch].
3749 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Added new function silc_idcache_del_by_context into the
3752 lib/silccore/idcache.[ch].
3754 * Changed the server's ID list routines to use the new ID Cache
3755 interface. Changes around the source tree.
3757 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Added silc_hash_table_del[_by_context]_ext functions in to the
3760 lib/silcutil/silchashtable.[ch].
3762 Removed silc_hash_table_find_all* routines and added new
3763 silc_hash_table_find_foreach to replace them.
3765 Added silc_hash_table_replace_ext function as extended
3766 replacing function. Separated the simple hash table interface
3767 from the extended hash table interface in the file
3768 lib/silcutil/silchashtable.h.
3770 * Fixed minor bugs and changed it to use some of the new
3771 hash table functions in lib/silccore/idcache.c
3773 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added new function silc_hash_table_find_all to return all keys
3776 in the hash table by the specified key. As the hash table is
3777 collision resistant it also makes it possible to have several
3778 duplicate keys in the hash table. This function may be used to
3779 find all of the keys from the hash.
3781 Added user_context arguments to the SilcHashFunction,
3782 SilcHashCompare and SilcHashDestructor to deliver user specified
3785 Added new fuctions silc_hash_table_find[_all]_ext to do
3786 extended lookup with specified hash and compare functions and
3787 specified user contexts.
3789 Added new function silc_hash_table_add_ext to add the key
3790 with specified hash function and user context.
3792 Added new function silc_hash_table_foreach to traverse all
3793 entrys in the hash table. Added SilcHashForeach callback
3796 Added new function silc_hash_table_del_by_context to delete
3797 the entry only if the context associated with the key matches.
3799 Affected files are lib/silcutil/silchashtable.[ch].
3801 * Removed silc_hash_[server/client/channel]_id and added just
3802 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3803 silc_hash_id_compare to compare two ID's using as the hash table
3804 comparison function. Added also silc_hash_data to hash
3805 binary data and silc_hash_data_compare to compare it.
3807 * Removed silc_idlist_find_client_by_hash as it is not needed
3808 anymore. Affected file silcd/idlist.[ch].
3810 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3811 to use internally the SilcHashTable. The new ID Cache is a lot
3812 faster than the old one. Some of the ID Cache interface was also
3813 rewritten and obsolete and stupid functions were removed.
3815 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Added entry_count field to the SilcHashTable to keep the number
3818 of the entries in the table. Implemented the function
3819 silc_hash_table_rehash. Added new function
3820 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3822 Fixed a minor bug in silc_hash_table_free.
3824 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3825 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3826 into the lib/silcutil/silcutil.[ch].
3828 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Implemented a collision resistant hash table into the
3831 lib/silcutil/silchashtable[ch]. See the header and the source
3832 for the SilcHashTable API.
3834 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Merged dotconf version 1.0.2 into lib/dotconf.
3838 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Do not compile anything in lib/silcsim/* if the SIM support
3841 is not enabled. The tree should now compile without problems
3844 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Compiled the SILC under cygwin. Compiled and tested briefly
3847 without problems. More tests needed. The SIMs didn't compile
3850 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3852 * Fixed possible crash in silc_get_username in the
3853 lib/silcutil/silcutil.c.
3855 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Fixed a va_arg in silc/client_ops.c.
3859 * Oops, RC5 routines were named AES and caused some problems
3860 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3862 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added new SilcIDIP structure into the lib/silccore/id.h and
3865 replaced the old `ip' fields from all SILC ID's to that type.
3866 This is a step towards IPv6 support.
3868 The silc_id_get_len takes now the ID as an extra argument.
3869 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3870 both IPv4 and IPv6 based ID's.
3872 The affected files are lib/silccore/id.[ch] and other files
3873 around the tree using these routines.
3875 * Removed the ID length arguments in server from various
3876 silc_server_send_notify_* routines -> they are not needed
3879 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Fixed memory leak in silc_encode_pem_file in the file
3882 lib/silcutil/silcutil.c.
3884 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Check minor version as well in the SKE. Affected files are
3887 silcd/protocol.c and lib/silcclient/protocol.c.
3889 * Added --identifier option to the server so that an identifier
3890 can be when creating the public key for the server. Affected
3891 file is silcd/silcd.c.
3893 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3894 lib/silccrypt/silcpkcs.c.
3896 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Register default ciphers and stuff when using -C option with
3899 the server. Affected file sildc/silcd.c.
3901 * Put back the servers public key filename format, it is better
3902 than the new one. For now, the client keys are saved with the
3903 new filename format. The affected file silc/client_ops.c.
3905 * Implemented the Cipher API for the rest of the ciphers that
3906 did not implement it or implemented it the wrong way.
3908 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Register default ciphers and stuff when using the -S option
3911 in the client. Affected file silc/silc.c. Same also when
3912 creating new key pair with -C option.
3914 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Fixed the silc_verify_public_key client operation function to
3917 save the public keys differently. The fingerprint is now
3918 used as filename and not the hostname. This way also the
3919 client keys are saved uniquely and not with hostnames. The
3920 affected file is silc/client_ops.c.
3922 * Trimmed the silc_hash_fingerprint function to remove extra
3923 whitespaces from the end of the fingerprint. The affected
3924 file is lib/silccrypt/silchash.c.
3928 * Added silc_cipher_register_default function to register all
3929 default ciphers. It can be used when configuration files
3930 does not exist and the application does not want any specific
3931 ciphers in any specific order.
3933 The SilcDList is now used as silc_cipher_list dynamically
3934 allocated cipher list. Removed the static list all together
3935 and now all ciphers must be allocated to the dynamic list.
3936 The silc_cipher_alloc routine was changed to check only the
3939 All silc_cipher_* routines that used to return int returns
3942 The affected files lib/silccrypt/silccrypt.[ch].
3944 * The same thing was done to silc_hash_* as for silc_cipher_*
3945 routines. Affected files lib/silccrypt/silchash.[ch].
3947 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3948 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3949 Added also silc_pkcs_[un]register[_default] functions.
3950 Removed the data_context from the PKCS API.
3952 * Added silc_hmac_register_default function to register default
3953 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3954 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3955 to unregister all hmacs at once.
3957 * Register the default ciphers, hash functions, PKCSs and HMACs
3958 if client's configuration file does not exist. The affected
3961 * The client did not load the hash functions from the SIM
3962 modules at all. Added support for this. Affected file is
3963 silc/clientconfig.c.
3965 * When decoding public key with silc_pkcs_public_key_decode, check
3966 the supported algorithm only if PKCS are registered. Affected
3967 file lib/silccrypt/silcpkcs.c. The same was done with the
3968 silc_pkcs_private_key_decode.
3970 * Fixed the SILC List routines to keep the list always in order.
3971 It used to change the list's order when traversing the list but
3972 not it preserves the order. Affected file lib/trq/silclist.h.
3974 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added the client library to use the SilcSocketConnection's
3977 reference counter (by silc_socket_dup) to prevent the bug that
3978 the socket object may be freed underneath async operation.
3980 * The name resolv library checking fixes in the configure.in.pre.
3983 * Created new version of the protocol drafts for future
3984 development. The -03 drafts are the ones that will be changed
3985 in the trunk now and the -02 will remain as they are.
3987 * Send list of CUMODE notifys to the router when announcing
3988 the channel users to the router. Affected file silcd/server.c.
3989 If the router receiving channel founder CUMODE for a channel
3990 that already has channel founder it will send CUMODE notify
3991 to the sender to remove the channel founder rights from the
3992 announced client. Affected file silcd/packet_receive.c.
3994 * The CUMODE notify may now use Server ID as well as the entity
3995 who changes the mode. Updated protocool specs.
3997 * Updated INSTALL and README files.
3999 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * New web pages in the http://silc.pspt.fi. The pages was
4006 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Implemented the [DenyConnectin] config section in the server.
4009 Added silc_server_config_denied_conn to check whether incoming
4010 connection is denied. Affected file silcd/serverconfig.[ch].
4012 * Do not check the ports when checking the incoming configuration
4013 data if the port is 0, meaning any. Affected file is
4014 silcd/serverconfig.c.
4016 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Fixed buffer overflow in silc_string_compare in the file
4019 lib/silcutil/silcutil.c.
4021 * Fixed double free in silc_server_command_leave in the file
4024 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Fixed the version checking in the server. Affected file is
4029 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Fixed the configuration data fetching when accepting new
4032 connections in the server. Affected file silcd/server.c.
4034 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added `sender_entry' argument to the function
4037 silc_server_packet_relay_to_channel so that we can check
4038 whether some destination actually belongs to the same route
4039 the sender belongs (ie, we must not resend the packet to the
4040 sender). Affected file silcd/packet_send.[ch].
4042 * Added `servername' field to the SilcClientEntry in the server
4043 to hold the name of the server where client is from. Affected
4044 file is silcd/idlist.h.
4046 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Moved the channel message encrypting in the router betwen
4049 router connections from silc_server_channel_message to the
4050 silc_server_packet_relay_to_channel since we want to check
4051 whether we have anybody channel before encrypting anything.
4052 Affected files silcd/packet_[receive/send].c.
4054 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Fixed the [AdminConnection] server config section to support
4057 multiple entries. Affected file silcd/serverconfig.c.
4059 * Added support into the server to check the validity of the
4060 incoming connection before executing any KE or authentication
4063 * The connection configuration is now saved to the KE and
4064 connection auth protocol contexts and not fetched anymore in
4065 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4067 * The local hosts listenning address and port is also resolved
4068 now when starting the server. We want to have the socket object
4069 to include the real address and port for the listener. Added
4070 new function silc_net_check_local_by_sock into the files
4071 lib/silcutil/silcnet.[ch].
4073 * Fixed a broadcast bug in server -> do not broadcast if we
4076 * Fixed a routing bug. Do not route broadcast packets ever.
4077 Broadcast packets must be processed always and not routed since
4078 they may be destined to some other host than yourself and thus
4079 would get routed without no good reason. Affected file is
4082 * Added function silc_server_config_is_primary_route to check
4083 whether primary router connection has been configured (a router
4084 configuration that we are initiating). If there is not, we
4085 will assume that there is only two routers in the SILC network
4086 and we will use the incoming router connection as our primary
4087 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4089 * Changed the order of the broadcasting. Broadcast _after_ the
4090 packet has been processed not before. Affected file is
4093 * Fixed a [ClientConnection] parsing bug. The port was never
4094 parsed correctly thus resulting to port 0. Affected file
4095 silcd/serverconfig.c.
4097 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4098 argument and did not set the broadcast packet flag. Affected
4099 file silcd/packet_send.c. Fixed same bug in the function
4100 silc_server_send_notify as well.
4102 * If we receive NEW_ID packet for our own ID in the server, ignore
4105 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Removed the nickname from the Private Message Payload.
4110 Updated the code and the protocol specs.
4112 * Updated protocol specs for submitting to the IETF.
4114 * Tweaked the Random Number Generator a bit. Affected file
4115 lib/silccrypt/silcrng.c. Exported a new function
4116 silc_rng_[global]_add_noise which can be used to add more
4119 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Do not parse packets with different timeout when protocol
4122 is active -> may cause problem with rekey. Affected file
4125 * When server receives signoff notify it must not create
4126 new channel key if the client is on any channels since the
4127 sender of the signoff notify will create it.
4129 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Added printing of error messages during SKE protocol from the
4132 failure packet sent by server during SKE. Affected file
4135 * Removed the client's failure_callback handling with timeout
4136 and handle it immediately when received.
4138 * The SKE library returned wrong type in SUCCESS and FAILURE
4139 packets. They must be 32 bit MSB not 16 bit MSB.
4141 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Ok, rewrote the logic of the re-key and now it seems to work.
4144 I tested it on high traffic with frequent re-keys without
4145 problems. Added hmac_receive (and renamed hmac to hmac_send)
4146 in SilcClientConnection in lib/silcclient/client.h and
4147 in SilcIDListData in silcd/idlist.h. Also, removed the
4148 SilcPacketParserContext's cipher and hmac fields as they are
4149 not needed anymore and actually caused some problems when
4150 the ciphers and hmac's changed underneath the packet parser.
4152 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * If re-key protocol is active then process the incoming packets
4155 synchronously since we must assure that icoming packets encrypted
4156 with the old key is processed before the new keys is set to
4157 use. This is true other packets than for REKEY packets.
4158 Affected file silcd/server.c. The same was done to client library
4159 as well, affected file lib/silcclient/client.c.
4161 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Fixed bug in client and server to accept the force send if
4164 the packet is send from silc_[server/client]_packet_process
4165 function. Otherwise the packets are never delivered, oops.
4167 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Disable force sending of packets when REKEY protocol is active.
4170 We must assure that no packet is sent directly when rekey is
4171 performed. All packets must be sent through packet queue.
4172 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4173 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4174 function is silc_[server/client]_packet_send_real to check
4177 * Replaced the SIM paths from example config files to
4178 /usr/local/modules. Also, make install creates now
4179 /usr/local/silc/logs directory to hold all the SILC server
4182 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Made the configure.in.pre work on Solaris. Patch by salo.
4186 * Made all ciphers compatible with non-x86 machines. Defined
4187 CBC mode macros into lib/silccrypt/ciphers_def.h.
4189 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Fixed the make install.
4193 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * When MAC computation fails the silc_packet_decrypt returned 0
4196 even though it was supposed to return -1. Fixed this. The
4197 affected file is lib/silccore/silcpacket.c.
4199 * Do not replace the config files in /etc/silc (in make install)
4200 if they already exist. Affected file ./Makefile.am.
4202 * Do not send re-key packets immediately but through packet queue.
4203 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4205 * Changed silc_net_check_host_by_sock to return FALSE if the
4206 IP/DNS could not be resolved. Though, it returns the IP address
4207 now even if it could not resolve it (but returns also FALSE).
4208 Affected file lib/silcutil/silcnet.[ch].
4210 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Added silc_pkcs_decode_identifier to decode the public key's
4213 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4214 Added also silc_pkcs_free_identifier. Added also new context
4215 SilcPublicKeyIdentifier.
4217 * Added -S option to the silc client. It is used to dump the
4218 contents of the specified public key file.
4220 * Changed the PKCS api to return the public key length when
4221 setting the public key.
4223 * Fixed a fatal bug in the public and private key file loading.
4224 Affected file lib/silccrypt/silcpkcs.c.
4226 * Execute the packet parsing for client with zero (0) timeout
4227 if the protocol is active. Affected file silcd/server.c.
4229 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Made the key generation options to the silcd program. Added
4232 -C option, equivalent to client's option.
4234 * Added new [ServerKeys] config section to the server. It
4235 configures the server's public and private key.
4237 * Defined generic Public Key Payload into the protocol
4238 specification to send specific type of public keys and
4241 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4242 public key or certificate.
4244 * Implemented the GETKEY command to the server and to the
4245 client library and on user interface.

4253 * Added SilcServerRekey context into silcd/idlist.h.
4255 * Added the PFS support as defined in the specification to the
4256 SKE protocol. Affected files lib/silcske/*.c.
4258 * Added `ske_group' field to the SilcServerRekey context to hold
4259 the number of the SKE group that is used with PFS in re-key.
4260 Affected file silcd/idlist.h.
4262 * Added PFS re-key support to the server. Affected file is
4265 * Added silc_protocol_cancel to cancel execution of the next
4266 state of the protocol. Affected file is
4267 lib/silccore/silcprotocol.[ch].
4269 * Added the re-key support with and without PFS to the client
4270 library. Re-key is performed once in an hour, by default.
4272 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4273 Added silc_client_rekey_callback and silc_client_rekey_final.
4274 Affected files are lib/silcclient/protocol.[ch] and
4275 lib/silcclient/client.[ch].
4277 * Removed the `hmac_key' and `hmac_key_len' fields from the
4278 SilcClientConnection structure; not needed. Affected file is
4279 lib/silcclient/client.h.
4283 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Do not ask whether user wants to use the negotiated private key
4286 for private messages, just use it. Affected file is
4287 silc/local_command.c.
4289 * Added `send_enc_key' and `enc_key_len' fields to the
4290 SilcIDListData structure since they are needed in the re-key
4291 phase. Affected file is silcd/idlist.[ch].
4293 * Implemented the simple re-key protocol into the server.
4294 Affected files silcd/server.c and silcd/protocol.[ch]. The
4295 re-key will be performed once in an hour, by default.
4297 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4298 Added silc_server_rekey, silc_server_rekey_callback and
4299 silc_server_rekey_final.
4301 * Removed Tunneled flag from the protocol. Updated the code
4302 and the specifications.
4304 * Adde `pfs' field to the SilcIDListData to indicate whether
4305 the PFS is to be performed in the re-key. Affected file is
4308 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4311 int64 of at least the xintXX size. If void * is less that 4
4312 bytes uint32 * will be used. Defined bool as boolean.
4314 * Changed _ALL_ unsigned long and unsigned int to uint32,
4315 unsgined short to uint16 in the source tree.
4317 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4318 not handle clients that has entry->data.registered == FALSE.
4319 They are not in the network anymore. Affected file is
4322 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Implemented the sending of the SERVER_SIGNOFF notify in the
4325 server. Affected file is silcd/server.c.
4327 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4328 Added also silc_notify_payload_encode_args into the
4329 lib/silccore/silcnotify.[ch].
4331 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4332 Affected file silcd/packet_receive.c.
4334 * Implemented the SERVER_SIGNOFF notify handling in the client
4335 library. Affected file lib/silcclient/client_notify.c. Also,
4336 implemnted the printing of the SERVER_SIGNOFF info to the
4337 application. Affected file silc/client_ops.c.
4339 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4340 if the deleting was successful. Affected file silcd/idlist.[ch].
4342 * Added support for public key authentication in the connection
4343 authentication protocol in the client library. Affected file
4344 lib/silcclient/protocol.c.
4346 * Changed the server's silc_idlist_get_clients_by_* interface
4347 to support already allocated array so that new entries may be
4348 added to pre-allocated array. Affected file silcd/idlist.[ch].
4349 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4350 and command replies.
4352 * All command reply functions in the server now calls the
4353 pending command callback even if error occured. This way the
4354 error will be delivered to the client as well. Affected files
4355 silcd/command.c and silcd/command_reply.c.
4357 * Fixed INFO command to return local server's info if no server
4358 was provided. Affected file lib/silcclient/command.c.
4360 * Removed RESTART command for good. Updated the code and the
4363 * Rewrote parts of the task system. It is a bit simpler now.
4364 Removed unsued task priorities. The affected files are
4365 lib/silcutil/silctask.[ch].
4367 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Moved the USERS printing from the library to the application.
4370 Affected files lib/silcclient/command.c and silc/client_ops.c.
4372 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added channel key re-key support. The re-key is perfomed
4377 only by the router and is done once in an hour. Added `rekey'
4378 field to the SilcChannelEntry in the server. Affected files
4379 silcd/server.c and silcd/idlist.h.
4381 * Added silc_task_unregister_by_context into the file
4382 lib/silcutil/silctask.[ch].
4384 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Added SILC_UMODE_GONE mode to indicate when the client is not
4387 present in the SILC network. Added also support to the local
4388 command AWAY that will set this mode. Added support of showing
4389 "xxx is gone" in WHOIS command. The USERS command shows the
4390 gone status as well.
4392 * Fixed setting server and router operator privileges in the
4393 server's UMODE command. Affected file silcd/command.c.
4395 * Merged the SKE KE1 and KE2 payloads into one payload. The
4396 new KE payload is equivalent to the old KE2 payload.
4398 Cleaned up the SKE Start Payload parsing. It now uses the
4399 simple buffer unformatting to do the parsing. A lot faster
4402 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4403 to the SKE that is used to indicate whether both of the SKE
4404 parties should perform authentication. By default only the
4405 responder performs authentication. By setting this flag also
4406 the initiator must do authentication. By default it is unset
4407 since in normal SKE case, client to server connection, only
4408 the responder should do authentication. When doing SKE between
4409 two clients both should perform authentication. Updated the
4410 code and the protocol specs.
4412 * A little fix to IDENTIFY command in the server. Search the
4413 client first by hash not nickname. Affected file is
4416 * Fixed the silc_client_close_connection to support closing
4417 the client to client connections wihtout deleting too much
4418 data. Affected file lib/silcclient/client.c.
4420 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4421 are received if protocol used to be active but is not anymore
4422 the application would crash due to NULL pointer dereference.
4423 Affected files silcd/server.c and lib/silcclient/client.c.
4425 * Added `hash' field to the SilcClientConnection to include
4426 the hash function negotiated in the SKE protocol.
4428 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4429 to set the channel founder authentication data. A client can
4430 claim the founder rights later by providing the authentication
4431 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4432 This way the channel founder can regain the channel founder
4433 privileges even it is left the channel. This works only on
4434 local server and the client must be connected to the same
4435 server to be able to regain the founder rights. Updated the
4436 protocol specs accordingly.
4438 Added support to the CMODE command in the client to set the
4439 founder auth data. Read the README to see how to set it.
4441 Added support to the CUMODE command to claim the founder
4442 rights. Read the README to see how to do it.
4444 Added support for the founder authentication to the Channel
4445 Entry in the server. Affected file silcd/idlist.h.
4447 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4448 server's CMODE command. Affected file silcd/command.c.
4450 * Added the following new functions into lib/silccore/silcauth.[ch]:
4451 silc_auth_get_method and silc_auth_get_data.
4453 * The server now saves the remote hosts public key to the
4454 SilcIDListData pointer. Affected file silcd/protocol.c.
4456 * The normal server now does not remove the channel entry from
4457 the cache if the founder authentication data is set. It used
4458 to remove it if the founder was the last one on the channel on
4459 the server and left the channel. The auth data is saved and
4460 if the channel is re-joined later the old entry is used with
4461 the old auth data. Affected files silcd/command_reply.c and
4464 * Removed the `pkcs' field from the SilcIDListData structure
4465 in the server; it is not used. Affected file silcd/idlist.h.
4467 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Fixed packet processing on slow links. Partial packets were
4470 never re-processed because the incoming data buffer was cleared
4471 by the application. Application must not directly clear the
4472 sock->inbuf, the packet processing routines handle it. Fixed
4473 this in client library and in server.
4475 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Fixed the WHOIS and IDENTIFY send reply function to really
4478 check whether to send list or just one entry. Affected file
4481 * Cleaned up the LEAVE command's channel key distribution. The
4482 affected file silcd/command.c.
4484 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4485 can enforce the channel mode as well. In that case the ID
4486 includes the ID of the server. The code now enforces the
4487 mode change if the router have different mode than the server.
4489 * The notify client operation with CMODE_CHANGE notify can now
4490 return NULL client_entry pointer if the CMODE was not changed
4491 by client. Application must check for this.
4493 * Added <Server ID> argument to INFO command to support server
4494 info fetching by Server ID.
4496 * Added silc_server_announce_get_channel_users to get assembled
4497 packets of channel users of the specified channel. Affected
4498 file silcd/server.[ch].
4500 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4501 was freed underneath the ID Cache.
4503 * Re-announce clients when the server received CHANNEL_CHANGE
4504 notify from the router. Affected file silcd/packet_send.c.
4506 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4509 crashed since it did not handle the fact that there is no cipher
4510 called "3" and didn't check the error condition. Now fixed.
4512 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4513 flag. It can be used to send message requests.
4515 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Implemented the RESTART command in the client.
4519 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4520 notice type messages. Added notice printing to the user
4523 * The channel keys are not re-generated if the channel's mode
4524 is PRIVKEY, ie private key on the channel exists. Affected
4525 files silcd/server.c and silcd/command.c.
4527 * Fixed a little bug in channel message delivery when channel
4528 private keys are set in the server. Affected file is
4529 silcd/packet_send.c.
4531 * Changed the setting on channel->on_channel = TRUE from the
4532 silc_client_save_channel_key to the JOIN command reply. The
4533 key payload is not received if the private channel key is set.
4534 Affected file lib/silcclient/command_reply.c and the
4535 lib/silcclient/client_channel.c.
4537 * When the CMODE_CHANGE notify is sent and the channel private
4538 key mode is removed the channel key must be re-generated in
4539 other cells as well. Added this support for the router in the
4540 silcd/packet_receive.c.
4542 * Added new local command NOTICE to send notice message on
4543 channel. Affected file silc/local_command.[ch].
4545 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added new local command ME to the client. It is used to send
4548 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4549 some action. Affected file silc/local_command.[ch].
4551 * Changed channel_message and private_message client operations
4552 to deliver the message flags to the application. Added also
4553 the `flags' arguments to the silc_client_send_channel_message
4554 and silc_client_send_private_message functions. Affected file
4557 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Redefined the Private Message Payload to support private message
4560 keys and to support the new private message flags. Updated
4561 the protocol specs. Flags makes it possible to have for example
4562 CTCP style messages.
4564 * Added new type SilcPrivateMessagePayload and defined an API
4565 for it in the lib/silcclient/silcprivate.[ch].
4567 * Tested private message private keys successfully. Tested the
4568 private message key set, unset and list commands with the new
4571 * Redefined the Channel Message Payload to include the channel
4572 message flags (equal with private message flags) to support
4573 for example CTCP style messages.
4575 * Defined some of the message (for channel and private message)
4576 flags. Updated the protocol specs and added the flags to the
4577 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4579 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added SilcKeyAgreementStatus type to the key agreement routines
4582 to indicate the current status and error if one occured.
4583 The status types are defined in the lib/silcclient/silcapi.h.
4585 * Added new local command KEY that is used to set and unset private
4586 keys for channels, set and unset private keys for private messages
4587 with remote clients and to send key agreement requests and
4588 negotiate the key agreement protocol with remote client. The
4589 key agreement is supported only to negotiate private message keys,
4590 it currently cannot be used to negotiate private keys for channels,
4591 as it is not convenient for that purpose.
4593 * Fixed a minor pending callback setting bug in the function
4594 silc_client_get_client_by_id_resolve, now the function works.
4595 Affected file lib/silcclient/idlist.c.
4597 * Added function silc_net_get_local_port to get local bound
4598 port by socket. Added to lib/silcutil/silcnet.[ch].
4600 * Added `sockets' and `sockets_count' fields to the SilcClient
4601 object. They hold the sockets of the listenning sockets in
4602 the client. Listenning sockets may be for example the key
4603 agreement server. Affected file lib/silcclient/client.[ch].
4604 Added functions the silc_client_add_socket and the
4605 silc_client_del_socket. They are exported to the application
4608 * Added ~./silc/clientkeys to support other client's public keys.
4610 * Renamed verify_server_key client operation to verify_public_key
4611 and added one argument to indicate the type of the connection
4612 (server, client etc.).
4614 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Added silc_server_connection_auth_request to handle the
4617 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4618 silcd/packet_receive.[ch].
4620 * Added silc_server_send_connection_auth_request into the
4621 silcd/packet_send.c to send the connection auth request packet.
4623 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4626 * Fixed the public key authentication in responder side in the
4627 server. The `auth_data' pointer includes the SilcPublicKey
4628 not the path to the public key. Affected file silcd/protocol.c.
4630 * Implemented the public key authentication in the initiator side
4631 in the server. Affected file silcd/protocol.c.
4633 * Removed the [RedirectClient] config section from the server
4634 configuration. Is not needed and I don't want to implement it.
4636 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Cleaned up the CMODE command in the server. It now works
4639 correctly and supports all the modes defined in the protocol.
4640 Affected file is silcd/command.c.
4642 * Added `hmac_name' field to the SilcChannelEntry in the server
4643 to hold the default HMAC of the channel. It can be set when
4644 creating the channel (with JOIN command). Affected files
4647 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4648 type to indicate the change of the current cipher and hmac
4649 on the channel. Client can safely ignore the <cipher> argument
4650 (if it chooses to do so) since the CHANNEL_KEY packet will
4651 force the channel key change anyway. The <hmac> argument is
4652 important since the client is responsible of setting the new
4653 HMAC and the hmac key into use.
4655 * Fixed the CMODE command in the client library as well.
4657 * Tested CMODE command in router environment successfully.
4659 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Show the version of the remote client (or server) when connecting
4662 to the server. It is logged to the log file. Affected file
4663 is silcd/protocol.c.
4665 * Fixed the KILLED notify handling in the client library. The
4666 client must be removed from all channels when receiving the
4669 Also, do not remove the client entry when giving the KILL
4670 command but when the KILLED notify is received.
4672 * Removed silc_idlist_find_client_by_nickname from the server.
4673 Not needed anymore. Affected files silcd/idlist.[ch].
4675 * Implemented the CHANNEL_CHANGE notify type handling to the
4676 server. Affected file silcd/server.c.
4680 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added silc_server_send_notify_invite to send the INVITE
4683 notify between routers.
4685 * Implemented the INVITE command correctly to the server.
4687 * Implemented the INVITE notify type handling in the server.
4689 * Implemented the INVITE command to the client library and on the
4692 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added function silc_server_get_client_resolve to find the
4695 client entry by ID from all ID lists and then resolve it
4696 (using WHOIS) if it cannot be found. Affected file is
4699 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Implemented the BAN command to the client library.
4703 * The JOIN command in the server now checks the invite list
4706 * Changed the silc_command_reply_payload_encode_va and the
4707 silc_command_payload_encode_va to support that if argument is
4708 NULL it ignores and checks the next argument. Affected file
4709 lib/silccore/silccommand.c.
4711 * Added silc_server_send_notify_ban to send the BAN notify
4712 type between routers.
4714 * Chaned the silc_notify_payload_encode to support that if
4715 argument is NULL it ignores and checks the next argument.
4716 Affected file lib/silccore/silcnotify.c.
4718 * Tested ban lists in router environment successfully.
4720 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Implemented BAN command to the server, in silcd/command.[ch].
4724 * Removed the BAN and INVITE_LIST modes from the CMODE command
4727 * Added function silc_string_match to regex match two strings.
4728 Affected files lib/silcutil/silcutil.[ch].
4730 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Redefined parts of the SilcChannelEntry in the server to support
4733 the new ban and invite lists.
4735 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Redefined the INVITE command. The same command can be used to
4738 invite individuals to the channel but also to manage the invite
4739 list of the channel (to add to and remove from the invite list).
4740 Updated the protocol specs.
4742 * Added new command SILC_COMMAND_BAN that can be used to manage
4743 the ban list of the channel. Updated the protocol specs.
4745 * Removed the channel modes: the SILC_CMODE_BAN and the
4746 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4747 in the CMODE command. The equivalent features are now available
4748 using INVITE and BAN commands. Updated the protocol specs.
4750 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4751 in the network about change in the current ban list. The notify
4752 type is not used by the client.
4754 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4755 support the invite lists.
4757 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added new function silc_string_regexify that converts string
4760 including wildcard characters into regex string that can
4761 be used by the GNU regex library. Added into the file
4762 lib/silcutil/silcutil.[ch].
4764 Added silc_string_regex_combine to combine to regex strings
4765 into one so that they can be used as one regex string by
4766 the GNU regex library. Added into the file
4767 lib/silcutil/silcutil.[ch].
4769 Added silc_string_regex_match to match two strings. It returns
4770 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4772 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Imported GNU regex to the soruce tree into lib/contrib.
4775 Fixed some compiler warning from the regex.c.
4777 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Fixed MOTD command in the server to work in router environment.
4781 * Fixed the MOTD command in the client library to support
4782 the server argument in the command.
4784 * Added `nickname_len' argument to the silc_idlist_add_client
4785 in the server, as the `nickname' argument may be binary data
4788 * Added silc_idlist_get_channels to return all channels from
4791 * Implemented LIST command to the server. Affected file is
4794 * Implemented the LIST command to the client library and on the
4797 * Added [<user count>] argument to the LIST command reply.
4798 With private channels the user count is not shown.
4800 * Updated TODO and README.
4802 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * The client entry's data.registered must be TRUE even with
4805 global client entry on global client list. The data.registered
4806 is used to check whether the client is anymore in the network,
4807 for example with WHOWAS command so it must be valid.
4809 * Fixed the WHOWAS command in the server. It now actually works
4810 in router environment. Added function into silcd/command_reply.c
4811 silc_server_command_reply_whowas_save.
4813 * Added silc_idlist_purge function to the silcd/idlist.c
4814 to periodically purge the ID Cache.
4816 * Fixed INFO command in the server. It works now in router
4817 environment. Added <server name> argument to the INFO command
4818 reply. Updated the protocol specs.
4820 * Fixed minor bug in silc_idcache_purge to not purge if the
4821 expire value is zero.
4823 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4824 they were buggy because of the WHOWAS information.
4826 * Fixed local command MSG to handle the async resolving of
4827 the remote client properly. It used to fail the first MSG.
4828 Affected file silc/local_command.c.
4830 * Added `data_len' field to SilcIDCache context.
4832 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Update TODO. Todo in commands in the server.
4836 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4839 used by routers as broadcast packet to inform other routers
4840 about the changed user mode.
4842 Implemented the notify handling in the server. Affected file is
4843 silcd/packet_receive.c. Added the function
4844 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4846 * Added new generic Channel Payload and deprecated the New Channel
4847 Payload. The New Channel Payload is now the generic Channel
4850 * Added new argument `mode' to the silc_server_send_new_channel
4851 as it is required in the Channel Payload now.
4853 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4854 and created a new and real SilChannelPayload to represent the
4855 new generic Channel Payload. Implemented the encode/decode
4856 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4858 * Added silc_server_get_client_channel_list to return the list
4859 of channels the client has joined for WHOIS command reply.
4860 Affected file silcd/server.[ch].
4862 * Implemented the channel list sending in the WHOIS command reply
4863 in server and in the client.
4865 Implemented the channel list displaying on the user interface
4866 as well. Affected file silc/client_ops.c.
4868 * Added silc_channel_payload_parse_list to parse list of Channel
4869 Payloads. It returns SilcDList list of SilcChannelPayloads.
4870 Client for example can use this function to parse the list of
4871 channels it receives in the WHOIS command reply. The caller
4872 must free the list by calling silc_channel_payload_list_free.
4873 Affected files lib/silccore/silcchannel.[ch].
4875 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Added one new argument <user mode> to the WHOIS command reply
4878 to return the mode of the user in SILC. Updated the protocol
4881 Implemented it to the server and client.
4883 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Fixed the mode printing on the user interface on joining.
4886 Affected file silc/client_ops.c.
4888 * Implemented the UMODE command and user modes in general to the
4889 client library and to the user interface.
4891 * Implemented the UMODE command to the server.
4893 * The server now sends UNKNOWN_COMMAND error status if client sends
4894 unknown command. Affected file silcd/command.c.
4896 * All server commands now handle the command identifier the right
4897 way when sending the command reply to the client. The client can
4898 use to identify the command replies with the identifier.
4900 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added silc_server_get_client_route to resolve the route to
4903 the client indicated by the client ID. Affected file is
4906 * Added silc_server_relay_packet as general function to relay
4907 packet to arbitrary destination. This deprecates functions
4908 like _send_private_message_key, _relay_notify etc. Affected
4909 file is silcd/packet_send.[ch].
4911 Removed silc_server_send_key_agreement,
4912 silc_server_send_private_message_key and
4913 silc_server_packet_relay_notify functions from the file
4914 silcd/packet_send.[ch].
4918 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4919 server. Affected file silcd/packet_receive.[ch].
4921 * Implemented the KILL command to the client. Implemented the
4922 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4923 Affected files lib/silcclient/command[_reply].c and
4924 lib/silcclient/client_notify.c. Implemented the KILL notify
4925 printing in the user inteface.
4927 * Fixed a lot silc_parse_nick memory leaks from the client
4928 library in the file lib/silcclient/command.c.
4930 * Changed the silc_server_send_notify_on_channels's `sender'
4931 argument from SilcSocketConnection to SilcClientEntry to
4932 check the sender as entry and not as connection object and not
4933 to send to the client provided as argument. The affected file
4934 is silcd/packet_send.[ch].
4936 * The notify packets that are destined directly to the client used
4937 to not to be processed by the server. Now changed that and the
4938 server processes all notify packets. After relaying the packet
4939 to the client the notify packet is processed in the server.
4941 * The silc_server_free_client_data now checks whether there is
4942 pending outgoing traffic for the client and purges the data to
4943 the network before removing the client entry.
4945 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4948 an client is killed from the SILC Network. Updated the protocol
4951 Added new function silc_server_send_notify_killed to the
4952 silcd/packet_send.[ch].
4954 * Added function silc_server_packet_relay_notify to relay notify
4955 packets that are destined directly to a client. In this case
4956 the server does not process the notify packets but merely relays
4957 it to the client. Affected file silcd/packet_send.[ch].
4959 Added also silc_server_packet_process_relay_notify to check
4960 whereto relay the notify. Affected file is
4961 silcd/packet_receive.[ch].
4963 * Implemented the KILL command to the server.
4967 * Added the backup schema desgined last fall to the protocol
4968 specs for everyone to see. The specification is in the
4969 *-spec-xx.txt draft and the packet type definitions for the
4970 backup routers is in *-pp-xx.txt draft. Thusly, added also
4971 new packet type SILC_PACKET_CELL_ROUTERS.
4973 * A big security problem in the implementation discovered. The
4974 signoff of an client did not cause new channel key generation
4975 which it of course should've done. The channel keys must be
4976 always re-generated when client leaves (or signoffs) the channel.
4977 The silc_server_remove_from_channels funtion now handles
4978 the channel key re-generation.
4980 * Added `sender' argument to the silc_server_send_notify_on_channels
4981 to not to send the client provided as argument. Affected file
4982 silcd/packet_send.[ch].
4984 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Implemented OPER and SILCOPER commands into the server and
4989 * Added silc_auth_verify and silc_auth_verify_data to verify
4990 the authentication directly from the authentication payload.
4991 It supports verifying both passphrase and public key based
4992 authentication. Affected file lib/silccore/silcauth.[ch].
4994 * Added `hash' field to the SilcIDListData structure. It is the
4995 hash negotiated in the SKE protocol. Affected file is
4998 * Slight redesigning of the SilcAuthPayload handling routines.
4999 Do not send SilcPKCS but SilcPublicKey as argument.
5001 * Implemented the public key authentication support to the
5002 serverconfig. The public key is loaded from the provided path
5003 and saved as authentication data to void * pointer. Thus,
5004 changed the unsigned char *auth_data to void *auth_data;
5006 * Fixed SHUTDOWN command to send the reply before the server
5007 is shutdown. :) Affected file silcd/command.c.
5009 * Fixed fatal bug in CONNECT command. The hostname was invalid
5010 memory and server crashed. Affected file silcd/command.c.
5012 * Fixed fatal bug in CLOSE command. The server_entry became
5013 invalid but was referenced later in the command. Affected file
5016 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Fixed fatal bug in failure packet handling. Server ignored
5019 the failure and thus crashed when it came.
5023 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5026 that the command may be executed only once in (about) 2 seconds.
5027 The old SILC_CF_LAG flag is same but allows command bursts up
5028 to five before limiting.
5030 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5031 server code. Various commands now includes the CF_LAG_STRICT
5032 flag to disallow any kind of miss-use of the command.
5034 * Fixed the silc_buffer_unformat to not to allocate any data
5035 if the length of the data is zero. It used to allocate the
5036 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5038 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Changed the format of AdminConnection configuration section
5041 in the server. Added username of the admin to the format.
5042 Affected files silcd/serverconfig.[ch].
5044 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5045 to return admin configuration data by host, username and/or
5048 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Implemented WHOWAS command to the server. Added the functions:
5052 silc_server_command_whowas_parse,
5053 silc_server_command_whowas_send_reply,
5054 silc_server_command_whowas_from_client and
5055 silc_server_command_whowas_from_server
5057 * Added <Client ID> argument to the WHOWAS command reply. Updated
5058 the protocol specs accordingly.
5060 * Implemented WHOWAS command and command_reply to the client
5063 Implemented the WHOWAS printing on the user interface.
5065 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added new argument to the WHOWAS command reply, the real name.
5068 It is an optional argument. Updated the protocol specs.
5070 * Added SilcIDCacheDestructor callback that is registered when
5071 the SilcIDCache is allocated. The callback is called when
5072 an cache entry in the ID Cache expires, or is purged from the
5073 cache. Added into lib/silccore/idcache.[ch].
5075 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5076 to destruct the client entries when the cache entry expires.
5077 Other ID Cache's in server and in the client library ignores
5080 * If the ID Cache entry's `expire' field is zero then the entry
5081 never expires. Added boolean `expire' argument to the
5082 silc_idcache_add function in the lib/silccore/idcache.[ch].
5083 If it is TRUE the default expiry value is used.
5085 * Added silc_server_free_client_data_timeout that is registered
5086 when client disconnects. By default for 5 minutes we preserve
5087 the client entry for history - for WHOWAS command.
5089 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Added support to the server to enforce that commands are not
5092 executed more than once in 2 seconds. If server receives
5093 commands from client more frequently, timeout is registered
5094 to process the commands. Affected file silcd/command.c.
5095 Added new function silc_server_command_process_timeout.
5097 * Changed NICK_NOTIFY handling in client library to check that
5098 if the client's nickname was changed, so there is no need to
5099 resolve anything from the server.
5101 * Removed error printing from the WHOIS and IDENTIFY commands.
5102 If error occurs then it is ignored silently in the client library.
5103 The application, however, may map the received error to
5104 human readable error string. The application currently maps
5105 the NO_SUCH_NICKNAME error to string.
5107 * Made the command status message public to the application. Moved
5108 them from lib/silcclient/command_reply.c to
5109 lib/silcclient/command_reply.h. The application can map the
5110 received command status to the string with the
5111 silc_client_command_status_message function.
5113 * Added check to the server to check that client's ID is same
5114 as the Source ID in the packet the client sent. They must
5117 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added dist-bzip hook to the Makefile.am to make bzip2
5120 compressed distributions.
5122 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Server now enforces the maximum length for the nickname and
5125 the channel as protocol specification dictates. 128 bytes for
5126 nickname and 256 bytes for channel name.
5128 * Moved the WHOIS printing to the application. The client libary
5129 does not print out the WHOIS information anymore, the application
5130 must do it. Renamed silc_client_command_reply_whois_print to
5131 the silc_client_command_reply_whois_save.
5133 The client's idle time is also sent to the application now, and
5134 the idle is shown on screen.
5136 * Added silc_client_command_reply_identify_save to save the
5137 received IDENTIFY entries.
5139 * Do not check for channel private keys in message sending and
5140 reception if the channel does not have the PRIVKEY mode set.
5141 Affected file lib/silclient/client_channel.c.
5143 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5146 just surfaced after chaning the JOIN procedure.
5148 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Added silc_client_get_clients_by_list to get client entries
5151 from Client ID list, that is returned for example by JOIN
5152 and USERS command replies. The application should use this
5153 function for example when JOIN command reply is received to
5154 resolve the clients already on the channel (library does not
5155 do that anymore as USERS command reply is not used in the JOIN
5156 procedure anymore). Affected files lib/silcclient/silcapi.h and
5157 lib/silcclient/idlist.c.
5159 * JOIN command reply and USERS command reply returns now SilcBuffer
5160 pointers instead of unsigned char pointers when returning
5161 the client list and mode list.
5163 * Added <Client ID> argument to the JOIN command reply, mainly
5164 for the server to identify for which client the command was
5165 originally sent. Updated protocol specs accordingly.
5167 * Added SilcDlist private_key pointer to the SilcChannelEntry
5168 in the client to support the channel private keys. Affected
5169 file is lib/silcclient/idlist.h.
5171 * Added SilcChannelPrivateKey argument to the function
5172 silc_client_send_channel_message so that application can choose
5173 to use specific private ke if it wants to. If it is not provided,
5174 the normal channel key is used, unless private keys are set.
5175 In this case the first (key that was added first) is used
5176 as the encryption key.
5178 * Implemented the support for channel private key handling.
5179 Implemented the following functions:
5181 silc_client_add_channel_private_key,
5182 silc_client_del_channel_private_keys,
5183 silc_client_del_channel_private_key,
5184 silc_client_list_channel_private_keys and
5185 silc_client_free_channel_private_keys
5187 Affected file lib/silcclient/client_channel.c.
5189 * Added the support for the private keys in the channel message
5190 sending and encryption and in the message reception and
5191 decryption. Affected funtions are
5192 silc_client_send_channel_message and silc_client_channel_message.
5194 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added SKE's key verify callback to the client library's
5197 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5199 * Removed the statement that server (or router) must send USERS
5200 command reply when joining to the channel so that the client
5201 knows who are on the channel. Instead, the client list and
5202 client's mode list is now sent in the JOIN command reply to the
5203 client who joined channel. This is better solution.
5205 * Added function silc_server_get_users_on_channel and function
5206 silc_server_save_users_on_channel to the silcd/server.[ch].
5208 * Removed function silc_server_command_send_users from the
5211 * Do not show topic on the client library anymore. The topic is
5212 sent in the command reply notify to the application and the
5213 application must show the topic now.
5215 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Added client searching by nickname hash into the IDENTIFY and
5218 WHOIS commands in the server as they were clearly missing from
5219 them. Affected file is silcd/command.c.
5221 * Fixed a bug in private message receiving in the client library.
5222 The remote ID was freed and it wasn't supposed, now it is
5225 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Minor fix to the channel payload; allocate the data area, as it
5228 needs to be of specific length.
5230 * If the key agreement port is zero then the operating
5231 system will define the bound port. Affected files are
5232 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5234 * Added new function silc_channel_payload_decrypt into the file
5235 lib/silccore/silcchannel.[ch].
5237 * Moved the channel message etc, check from silc_packet_decrypt
5238 to applications. The library calls now a generic
5239 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5240 when the packet is either normal or special. This was done to
5241 allow more wide range of checking that was not allowed when
5242 the code was in library. Now applications can do virtually any
5243 checks to the packet and return to the library the decision how
5244 the packet should be processed. Affected files are
5245 lib/silccore/silcpacket.[ch].
5247 Added silc_server_packet_decrypt_check to the server and
5248 silc_client_packet_decrypt_check to the client library.
5250 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5251 to send with specified source and destination information.
5253 * Channel message delivery between routers was broken after the
5254 channel key distribution was fixed earlier. The channel key
5255 was used be to distributed to other routers as well which is not
5256 allowed by the protocol. Now this is fixed and channel keys
5257 really are cell specific and the channel message delivery between
5258 routers comply with the protocol specification.
5260 * Fixed various commands in server to check also the global list
5261 for the channel entry and not just the local list. The affected
5262 file silcd/command.c.
5264 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * Added assert()s to buffer formatting and unformatting routines
5267 to assert (if --enable-debug) when error occurs. Affected
5268 file: lib/silcutil/silcbuffmt.c.
5270 * Changed to auto-reconnect to check whether the remote host is
5271 router and register the re-connect timeout if it is. It used
5272 to check that whether we are normal server, but router must do
5273 auto-reconnect with another router as well. Affected file
5276 * Removed the [<key len>] option from CMODE command as the cipher
5277 name decides the key length, nowadays. See the defined ciphers
5278 from the protocol specification.
5280 * Added [<hmac>] option to the CMODE command to define the HMAC
5281 for the channel. Added SILC_CMODE_HMAC channel mode.
5283 * Added [<hmac>] option for the JOIN command so that user can
5284 select which HMAC is used to compute the MACs of the channel
5287 * Added Hmac field to the Channel Message Payload. The integrity
5288 of plaintext channel messages are now protected by computing
5289 MAC of the message and attaching the MAC to the payload. The
5290 MAC is encrypted. Now, it is clear that this causes some
5291 overhead to the size of the packet but rationale for this is that
5292 now the receiver can verify whether the channel message decrypted
5293 correctly and also when private keys are set for the channel the
5294 receiver can decrypt the packet with several keys and check from
5295 the MAC which key decrypted the message correctly.
5297 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5298 lib/silccrypt/silccipher.[ch].
5300 * Added silc_hash_len to return the digest length into the
5301 lib/silcrypt/silchash.[ch].
5303 * Rewrote parts of Silc Channel Payload interface in the
5304 lib/silccore/silcchannel.[ch]. The encode function now also
5305 encrypts the packet and parse function decrypts it.
5307 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed a minor formatting bug in the SKE's key material processing.
5310 It actually might have processed the keys wrong way resulting
5313 * Redefined the mandatory HMAC algorithms and added new algorithms.
5314 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5315 and hmac-md5 truncated to 96 bits. The mandatory is now
5316 hmac-sha1-96. Rest are optional (including the one that used
5317 to be mandatory). Rationale for this is that the truncated HMAC
5318 length is sufficient from security point of view and can actually
5319 make the attack against the HMAC harder. Also, the truncated
5320 HMAC causes less overhead to the packets. See the RFC2104 for
5323 * Added new [hmac] configuration section. The SKE used to use
5324 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5325 is of course wrong. The official names that must be proposed in
5326 the SKE are the ones defined in the protocol specification
5327 (hmac-sha1-96 for example). The user can configure any hmac
5328 using any hash function configured in the [hash] section. At
5329 least, the mandatory must be configured.
5331 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5333 * Added HMAC list to the SKE proposal list. It has now both
5334 hash algorithm list and HMAC list. This makes the protocol
5335 incompatible with previous versions. The SKE now seems to work
5336 the way it is supposed to work, for the first time actually.
5338 * Defined plain Hash algorithms to the protocol specification.
5341 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Implemented support for key agreement packets into the server.
5344 Added functions silc_server_key_agreement and
5345 silc_server_send_key_agreement. Other than these functions,
5346 server has nothing to do with this packet.
5348 * Added support for private message key packets into the server.
5349 Added functions silc_server_private_message_key and
5350 silc_server_send_private_message_key.
5354 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5355 called in the protocol's final callback instead in the END
5356 protocol state. This makes a little more sense and in the same
5357 time in client we can use the same protocol routines for normal
5358 key exchange and to key agreement packet handling as well.
5360 * Added to both client's and server's KE protocol context the
5361 SilcSKEKeyMaterial pointer to save the key material. We will
5362 bring the key material to the protocol's final callback by doing
5363 this. The final callback must free the key material.
5365 * Added SKE's packet_send callback into client's KE protocol
5366 context so that the caller can choose what packet sending function
5367 is used. This way we can use different packet sending when
5368 doing normal SKE when doing key agreement packet handling (in
5369 the key agreement packet handling we do not want to encrypt
5372 * Implemented the responder side of the key agreement routines
5373 in the client. The client can now bind to specified port and
5374 accept incoming key negotiation. The key material is passed
5375 to the application after the protocol is over.
5377 * Implemented the processing of incoming Key Agreement packet
5378 in the client. Added function silc_client_key_agreement to
5381 * Implemented the intiator side of the key agreement routines
5382 in the client. The client can now initiate key agreement with
5383 another remote client. The key material is passed to the
5384 application after the protocol is over.
5386 * Created client_keyagr.c to include all the key agreement
5389 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5390 SILC_TASK_CALLBACK except that it is not static.
5392 * Created client_notify.c and moved the Notify packet handling
5393 from the client.[ch] into that file.
5395 * Created client_prvmsg.c and moved all private message and
5396 private message key routines from the client.[ch] into that file.
5398 * Create client_channel.c and moved all channel message and
5399 channel private key routines from the client.[ch] into that file.
5401 * Changed silc_client_get_client_by_id_resolve to resolve with
5402 WHOIS command instead of IDENTIFY command, in the file
5403 lib/silclient/idlist.c.
5405 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Implemented the SKE's responder side to the Client library.
5409 * When FAILURE is received to the protocol do not trust it
5410 blindly. Register a timeout to wait whether the remote closes
5411 the connection as it should do it, only after that process the
5412 actual failure. This was changed to both client and server.
5414 * Added client_internal.h to include some of the structures
5415 there instead of client.h in lib/silcclient/.
5417 * Added function silc_task_unregister_by_callback to unregister
5418 timeouts by the callback function.
5420 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Some "Incomplete WHOIS info" errors has been appearing on the
5423 log files. Took away the entry->userinfo check from WHOIS
5424 reply sending. The entry->userinfo is now " " if client did not
5425 provide one. I thought this was fixed earlier but something
5426 is wrong still. Let's see if the error still appears.
5428 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Fixed a minor bug in the login when the channel key is
5431 re-generated in the server. It used to generate the key in
5432 wrong order and thus caused problems in the channel traffic.
5434 * Fixed a minor bug in channel key distsribution after
5435 KICK command. The key was not sent to the router even though
5438 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added silc_ske_process_key_material_data as generic routine
5441 to process any key material as the SILC protocol dictates. The
5442 function is used by the actual SKE library but can be used by
5443 applications as well. This relates to the private message keys
5444 and the channel private keys since they must be processed the
5445 same way the normal SILC session keys. The protocol dictates
5446 this. Affected files: lib/silcske/silcske.[ch].
5448 Added also silc_ske_free_key_material to free the
5449 SilcSKEKeyMaterial structure.
5451 * Defined silc_cipher_set_key function to set the key for
5452 cipher without using the object's method function. The affected
5453 files: lib/silccrypt/silccipher.[ch].
5455 * Implemented silc silc_client_add_private_message_key,
5456 silc_client_add_private_message_key_ske,
5457 silc_client_del_private_message_key,
5458 silc_client_list_private_message_keys and
5459 silc_client_free_private_message_keys functions in the
5462 Added functions silc_client_send_private_message_key to send
5463 the Private Message Key payload and silc_client_private_message_key
5464 to handle incoming Private Message Key payload.
5466 * Added Cipher field to the Private Message Key payload to set
5467 the cipher to be used. If ignored, the default cipher defined
5468 in the SILC protocol (aes-256-cbc) is used.
5470 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Removed lib/silcclient/ops.h file.
5474 Redefined parts of the SILC Client Library API. Created new
5475 file silcapi.h that deprecates the ops.h file and defines the
5476 published Client Library API. Defined also private message key
5477 API and channel private key API into the file.
5479 This is the file that the application must include from the
5480 SILC Client Library. Other files need not be included by
5481 the application anymore.
5483 * Added new key_agreement client operation callback and also
5484 defined the Key Agreement library API for the application.
5486 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5489 is used by clients to request key negotiation between another
5490 client in the SILC network. If the negotiation is started it
5491 is performed using the SKE protocol. The result of the
5492 negotiation, the secret key material, can be used for example
5493 as private message key.
5495 Implemented the Key Agreement payload into the files
5496 lib/silccore/silauth.[ch].
5498 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Redefined ciphers for the SILC protocol. Added some new ciphers
5501 and defined the key lengths for the algorithms. Changed the
5502 code accordingly. The default key length is now 256 bits.
5504 * Fixed SKE key distribution function silc_ske_process_key_material
5505 when the key length is more than 128 bits. The default key
5506 length in SILC is now 256 bits.
5508 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5509 to indicate unsupported algorithm.
5511 * Renamed rijndael.c to aes.c and all functions as well.
5513 * Fixed a long standing channel key setting bug in client library.
5514 Weird that it has never surfaced before.
5516 * Fixed bug in channel deletion. If the entire channel is removed
5517 then it must also delete the references of the channel entry
5518 from the client's channel list as the client's channel entry and
5519 the channel's client entry share same memory.
5521 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Implemented CONNECT and SHUTDOWN commands in the client.
5525 * Implemented CLOSE command to the client.
5527 * Added the function silc_idlist_find_server_by_name into the
5528 files silcd/idlist.[ch].
5530 Added the function silc_idlist_find_server_by_conn into the
5531 files silcd/idlist.[ch].
5533 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * DIE command was renamed to SHUTDOWN. Updated the both code
5538 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5539 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5541 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5544 * Added function silc_server_create_connection function to create
5545 connection to remote router. My server implementation actually
5546 does not allow router to connect to normal server (it expects
5547 that normal server always initiates the connection to the router)
5548 so the CONNECT command is only good for connecting to another
5551 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5554 or some other client was kicked from the channel.
5556 Implemented the handling of the notify type to both client
5559 Implemented silc_server_send_notify_kicked to send the KICKED
5560 notify. It is used to send it to the server's primary router.
5562 * Implemented the KICK command into server and client.
5564 * Added `query' argument to the silc_idlist_get_client function
5565 to indicate whether to query the client from server or not if
5568 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5569 to indicate that the client is not channel founder.
5573 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Removed the rng context from SilcPacketContext structure and
5576 changed that the packet routine uses the Global RNG API.
5578 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added support for quit message that client can "leave" on the
5581 channel when it quits the SILC. It is ditributed inside the
5582 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5584 Added silc_server_free_client_data that will take the
5585 signoff message as argument.
5587 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5589 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Updated parts of the protocol specification to keep it up
5594 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5597 payloads in one packet.
5599 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5600 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5601 use now the new List flag.
5603 * Also deprecated the following packet types: REPLACE_ID,
5604 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5606 * Added list support for Notify packet in server.
5608 * Added silc_server_send_notify_channel_change to send the
5609 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5610 the silc_server_send_replace_id.
5612 * Added silc_server_send_notify_nick_change to send the
5613 NICK_CHANGE notify type. Deprecates the function
5614 silc_server_send_replace_id.
5616 * Added silc_server_send_notify_join to send the JOIN notify type.
5617 Deprecates the function silc_server_send_new_channel_user.
5619 * Added silc_server_send_notify_leave to send LEAVE notify type.
5620 Deprecates the function silc_server_send_remove_channel_user.
5622 * Added silc_server_send_notify_cmode and
5623 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5624 types. Deprecates the silc_server_send_set_mode function.
5626 * Added SERVER_SIGNOFF notify type to indicate that server has
5627 quit. This means that all clients on the channel from that
5628 server will drop. This can be also used when netsplit happens.
5630 Deprecated REMOVE_ID packet type since it is not needed anymore
5633 Added silc_server_send_notify_server_signoff to send the
5634 SERVER_SIGNOFF notify type. Deprecates the function
5635 silc_server_send_remove_id.
5637 Added also silc_server_send_notify_signoff to send the
5638 SIGNOFF notify type.
5640 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5641 SILC protocol from this day on. Changed the protocol
5642 specification as well.
5644 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5645 notify type. It is used between routers to notify about
5646 topic changes on a channel.
5648 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5651 * Partly updated the protocol specification to comply with the
5652 changes now made. It is still though a bit outdated.
5654 * The JOIN notify type now takes one extra argument <Channel ID>.
5655 The packet used to be destined to the channel but now the
5656 JOIN type may be sent as list thus it is impossible to
5657 destine it to any specific channel. By adding this argument
5658 it is again possible.
5660 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Added CREDITS file. The CHANGES and CREDITS file will appear
5663 in the distribution as well.
5665 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5668 types in the server's silcd/packet_receive.c.
5670 * Implemented CMODE and CUMODE to work in router environment.
5672 * Fixed minor encoding and decoding buglet from the
5673 lib/silccore/silcmode.c.
5675 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5678 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5680 * Changed all SilcConfigServer* and silc_config_server* to
5681 SilcServerConfig* and silc_server_config*, respectively.
5684 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Associated the ID (client or server ID) to the Authentication
5687 Payload to avoid any possibility of forging. Updated the
5688 protocol specification and the code accordingly.
5690 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * The RSA key length is now save to the RsaKey context in the
5693 key generation process in lib/silccrypt/rsa.c. The key length
5694 is now used to figure out the maximum size of the block allowed
5695 to be encrypted/signed.
5697 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5698 is equivalent to the silc_mp_mp2bin but does not allocate any
5701 * Changed silc_mp_mp2bin API to take length argument. If it is
5702 non-zero then the buffer is allocated that large. If zero, then
5703 the size is approximated using silc_mp_sizeinbase, which however
5706 * Created Global RNG API which is global RNG that application can
5707 initialize. After initializing, any routine anywhere in the
5708 code (including library) can use RNG without allocating a new
5709 RNG object. This was done to allow this sort of use of the
5710 RNG in code that has no chance to allocate RNG object. All
5711 applications currently allocate this and many routines in the
5712 library use this. Affected file lib/silccrypt/silcrng.[ch].
5714 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5715 it to use the Global RNG API.
5717 * Defined Authentication Payload into protocol specification that
5718 is used during SILC session to authenticate entities. It is
5719 used for example by client to authenticate itself to the server
5720 to obtain server operator privileges.
5722 Implemented this payload into the lib/silccore/silcauth.[ch].
5723 Implemented also routines for public key based authentication
5724 as the new protocol specification dictates.
5726 Moved definitions of different authentication methods from
5727 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5729 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5730 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5731 silc_pkcs_verify_with_hash functions into the file
5732 lib/silccrypt/silcpkcs.[ch].
5734 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * The client entry's userinfo pointer must be always valid.
5737 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5738 will fail since it requires the userinfo. Now, the userinfo
5739 is allocated as "" if actual userinfo does not exist. Actually,
5740 it must exist and it is totally Ok to drop client connections
5741 that does not announce the userinfo. However, we will make
5742 this workaround for now.
5744 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5745 to return the remote port by socket.
5747 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5750 SILC_SERVER_PENDING_EXEC and added an new macro
5751 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5752 data or when error occurs while processing the pending command.
5754 Added new argument `destructor' into silc_server_command_pending
5755 and to the SilcServerCommandPending object. This destructor is
5756 now called after calling the pending callback or if error occurs
5757 immediately. If error occurs the actual pending callback won't
5758 be called at all - only the destructor. The destructor may be
5759 NULL if destructor is not needed.
5761 All this applies for client library code as well. Similar
5762 changes were made there as well for the pending commands.
5764 In the client, the application must now allocate the
5765 SilcClientCommandContext with the silc_client_command_alloc
5768 * Added reference counter to the SilcServerCommandContext. Added
5769 function silc_server_command_alloc and silc_server_command_dup
5772 Same type of functions added to the client library for the same
5775 * Removed the cmd_ident from IDListData away since it is now
5776 global for all connections. It is the command identifier used
5777 in command sending and with pending commands. The affected file
5780 * Added reference counter to the SilcSocketConnection objecet to
5781 indicate the usage count of the object. The object won't be
5782 freed untill the reference counter hits zero. Currently only
5783 server uses this, and client ignores it. The client must be
5784 set to use this too later. The affected files are
5785 lib/silccore/silcsockconn.[ch]. Added also the function
5786 silc_socket_dup to increase the reference counter.
5788 This was mainly added because it is possible that the socket
5789 is removed underneath of pending command or other async
5790 operation. Now it won't be free'd and proper DISCONNECTING
5791 flags, etc. can be set to avoid sending data to connection that
5792 is not valid anymore.
5794 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5795 the connection. After that it sets SILC_SET_DISCONNECTED.
5796 It is, however, possible that the socket data is not still freed.
5797 The silc_server_packet_process now checks that data is not
5798 read or written to connection that is DISCONNECTED. The socket
5799 get's freed when the reference counter hits zero.
5801 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Changed the client operation API: channel_message operation's
5804 `sender' is now the client entry of the sender, not the nickname
5805 and the `channel' is the channel entry, not the channel name.
5807 In the private_message operation the `sender' is now also the
5808 client entry of the sender not the nickname.
5810 Affected file is lib/silcclient/ops.h and all applications
5811 using the client operations.
5813 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Moved the calling of ops->connect() from connect_to_server_final
5816 into receive_new_id functin since that is the point when the
5817 client is actually allowed to send traffic to network. The
5818 affected file is lib/silcclient/client.c.
5820 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5823 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5824 (if needs broadcasting) instead of broadcasting the packets one
5825 by one which would make a burst in the network traffic.
5827 * Added `broadcast' argument to the functions in silcd/server.[ch]
5828 silc_server_create_new_channel[_with_id] to indicate whether
5829 to send New Channel packet to primary router.
5831 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Added new function into the silcd/server.[ch] files:
5834 silc_server_create_new_channel_with_id to create new channel with
5835 already existing Channel ID.
5837 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5838 lib/silccore/silcpacket.h. This packet is used t send list of
5839 Set Mode payloads inside one packet. Server uses this to set
5840 the modes for the channels and clients on those channels, that it
5841 announced to the router when it connected to it. The protocol
5842 specification has been updated accordingly.
5844 * The silc_server_new_channel did not handle the packet coming
5845 from normal server as it normally does not send that. However,
5846 when it announces its channels it does send it. Implemented
5847 the support for that.
5849 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5850 into the file lib/silccore/id.h.
5852 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Fixed memory leaks in the functions silc_idlist_del_client,
5855 silc_idlist_del_channel and silc_idlist_del_server in the file
5856 silcd/idlist.c. All of those leaked like a sieve.
5858 * Fixed some small memory leaks in the client's function
5859 silc_client_notify_by_server.
5861 * Added functions into silcd/server.c: silc_server_announce_clients,
5862 silc_server_announce_channels and silc_server_announce_server.
5863 These functions are used by normal and router server to announce
5864 to its primary router about clients, channels and servers (when
5865 router) that we own. This is done after we've connected to the
5868 These functions effectively implements the following packet types:
5869 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5870 and SILC_PACKET_NEW_ID_LIST.
5872 * Added new functions into the silcd/packet_receive.[ch]:
5873 silc_server_new_id_list, silc_server_new_channel_list and
5874 silc_server_new_channel_user_list to handle the incoming
5875 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5877 * Added support of changing Channel ID in the function
5878 silc_server_replace_id. If the server that announces a channel
5879 to the router already exists in the router (with same name but
5880 with different Channel ID), router is responsible to send
5881 Replace ID packet to the server and force the server to change
5882 the Channel ID to the one router has.
5884 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5885 client that the Channel ID has been changed by the router. The
5886 normal server sends this to the client. Client must start using
5887 the new Channel ID as the channel's ID.
5889 Implemented handling of this new type into lib/silcclient/client.c
5890 into the function silc_client_notify_by_server.
5892 * Added new function silc_idlist_replace_channel_id into the files
5893 silcd/idlist.[ch] to replace the Channel ID.
5895 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Call silc_server_command_identify_check always when processing
5898 the IDENTIFY command in silcd/command.c
5900 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5903 send keepalive packets. The packet can be sent by clients,
5904 servers and routers.
5906 Added function silc_socket_set_heartbeat into the file
5907 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5908 If not set, the heartbeat is not performed. The actual
5909 heartbeat is implemented in the low level socket connection
5910 library. However, application is responsible of actually
5913 Added silc_server_send_heartbeat to send the actual heartbeat
5914 packet into silcd/packet_send.[ch]. Server now performs
5915 keepalive with all connections.
5917 * Added silc_task_get_first function into lib/silcutil/silctask.c
5918 to return the timeout task with shortest timeout. There was a bug
5919 in task unregistration that caused problems. TODO has been
5920 updated to include that task system must be rewritten.
5922 * The client library will now resolve the client information when
5923 receiving JOIN notify from server for client that we know but
5924 have incomplete information.
5926 * Rewrote parts of silc_server_remove_from_channels and
5927 silc_server_remove_from_one_channel as they did not remove the
5928 channel in some circumstances even though they should've.
5930 * Encryption problem encountered in server:
5932 The LEAVE command used to send the Channel Key packet to the
5933 router immediately after generating it. However, the code
5934 had earlier sent Remove Channel user packet but not immediately,
5935 ie. it was put to queue. The order of packets in the router
5936 was that Channel Key packet was first and Remove Channel User
5937 packet was second, even though they were encrypted in the
5938 reverse order. For this reason, MAC check failed. Now, this
5939 is fixed by not sending the Channel Key packet immediately but
5940 putting it to queue. However, this is more fundamental problem:
5941 packets that are in queue should actually not be encrypted
5942 because packets that are sent immediately gets encrypted
5943 actually with wrong IV (and thus MAC check fails). So, packets
5944 that are in queue should be encrypted when they are sent to
5945 the wire and not when they put to the queue.
5947 However, the problem is that the current system has not been
5948 designed to work that way. Instead, the packet is encrypted
5949 as soon as possible and left to the queue. The queue is then
5950 just purged into wire. There won't be any fixes for this
5951 any time soon. So, the current semantic for packet sending
5954 o If you send packet to remote host and do not force the send
5955 (the packet will be in queue) then all subsequent packets to the
5956 same remote host must also be put to the queue. Only after the
5957 queue has been purged is it safe again to force the packet
5960 o If you send all packets immediately then it safe to send
5961 any of subsequent packets through the queue, however, after
5962 the first packet is put to queue then any subsequent packets
5963 must also be put to the queue.
5965 Follow these rules and everything works fine.
5967 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Added new function silc_server_remove_clients_by_server to
5970 remove all client entries from ID list when the server connection
5971 is lost. In this case it is also important to invalidate all
5972 client entires as they hold the invalid server entry. This
5973 fixes fatal bug when server has lost connection and will reconnect
5976 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Made some sanity checks to silc_server_daemonise like to check
5979 whether the requested user and group actually exists.
5981 * Added sanity check to SKE's silc_ske_responder_finish to check
5982 that the public and private key actually is valid.
5984 * Invalidate the client's nickname when receiving Replace ID
5985 packet and the Client ID is being replaced. This means that the
5986 server will query the nickname if someone needs it (client)
5989 * Sort the ID Cache in client library when the ID Cache data
5990 has changed (needs sorting).
5992 * Do not allow for SILC client to create several connections to
5993 several servers. The client does not support windows right now
5994 and generating multiple connections causes weird behaviour.
5996 Irssi-silc client does support windows and can handle several
5997 connections without problems, see: www.irssi.org and SILC plugin.
5999 * Fixed some places where client was added to the IDList. The
6000 rule of thumb is following (in order to get everything right):
6001 If the client is directly connected local client then the
6002 `connection' argument must be set and `router' argument must be
6003 NULL to silc_idlist_add_client function. If the client is not
6004 directly connected client then the `router' argument must
6005 bet set and the `connection' argument must be NULL to the
6006 silc_idlist_add_client function.
6008 * The funtion silc_server_packet_send_local_channel actually did
6009 not check whether the client was locally connected or not. It
6010 does that now. Fixed a bug related to LEAVE command.
6012 * Fixed Remove Channel User payload parsing bug in server's
6013 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6015 * The server's silc_server_save_channel_key now checks also the
6016 global ID list for the channel as it might not be in the local
6017 list. Fixed a bug related to LEAVE command.
6019 * Is this the end of the [<unknown>] buglet that has been lurking
6020 around for a long time? A little for loop fix in server's
6021 silc_server_command_whois_parse that is used by both IDENTIFY
6022 and WHOIS command. At least, this was a clear bug and a cause
6023 of one type of [<unknown>] buglet.
6025 * WHOIS and IDENTIFY commands call the function
6026 silc_server_command_[whois/identify]_check function even if
6027 we are not router server.
6029 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Added --with-gmp configuration option. If set the GMP
6032 is always compiled in the SILC source tree. If not set then
6033 it is checked whether the system has the GMP3 installed. If
6034 it has then the GMP won't be compiled (the system's headers
6035 and library is used), if it doesn't have it then the GMP is
6036 compiled in the SILC source tree.
6038 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Changed RSA private exponent generation to what PKCS #1
6041 suggests. We try to find the smallest possible d by doing
6042 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6043 not security fix but optimization.
6045 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added new config entry [Identity] to fork the server and run
6048 it as specific user and group. A patch from Bostik.
6050 * Imported Dotconf configuration library into lib/dotconf.
6051 This will be used to create the SILC configuration files later.
6052 It will appear in the distsribution after this commit.
6054 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * A big code auditing weekend happening. Auditing code for
6057 obvious mistakes, bugs and errors. Also, removing any code
6060 Removed files for being obsolete:
6062 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6063 inline in the file lib/silcutil/silcbuffer.h)
6065 o lib/silcutil/silcbufutil.c (the header has inline versions)
6067 Changed code to fix possible error conditions:
6069 o The buffer formatting routines now check that the destination
6070 buffer really has enough space to add the data. This applies for
6071 both buffer formatting and unformatting
6072 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6073 unformatting was changed to accomodate following rules:
6074 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6075 sent to the function while XXX_*STRING will not allocate or copy
6076 the data into the buffer. Instead it sets the pointer from the
6077 buffer into the pointer sent as argument (XXX_*STRING used to
6078 require that the pointer must be allocated already). This change
6079 makes this whole thing a bit more consistent and more optimized
6080 (note that the data returned in the unformatting with XXX_*STRING
6081 must not be freed now). The routines return now -1 on error.
6083 o Tried to find all code that use buffer_format and buffer_unformat
6084 and added return value checking to prevent formatting and
6085 especially unformatting errors and possible subsequent fatal
6088 o Changed ske->x and ske->KEY to mallocated pointers in
6089 lib/silcske/silcske.h. Fixed possible data and memory leak.
6091 o Added return value checking to all *_parse* functions. Fixed
6092 many memory leaks as well.
6094 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6095 so that buffer overflows would not happen. All code now also
6096 checks the return value as it can fail.
6098 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Added reconnection support to server if the normal server looses
6101 its connection to the router (for example if router is rebooted).
6102 The server performs normal reconnection strategy implemented
6103 to the server. Affected file silcd/server.c.
6105 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added new packet type SILC_PACKET_SET_MODE that is used to
6108 distribute the information about changed modes (for clients,
6109 channels and clients channel modes) to all routers in the
6110 network. Updated the protocol specification accordingly.
6112 Added functions into silcd/packet_send.c and
6113 silcd/packet_receive.c: silc_server_send_set_mode,
6114 silc_server_set_mode.
6116 Added new files silcmode.[ch] into lib/silccore that implements
6117 the encoding and decoding of Set Mode Payload. Added new type
6118 SilcSetModePayload. Moved the definitions of different modes
6119 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6121 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Oops, a little mistake in server's connection authentication
6124 protocol. The protocol is not ended with FAILURE but with
6125 SUCCESS if the authentication is Ok. :) Affected file is
6128 * Implemented NICK_CHANGE notify handling in server in the file
6129 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6130 the local clients on the channel. After the changing nickname
6131 in router environment snhould work and the [<unknown>] nickname
6132 should appear no more.
6134 The silc_server_replace_id function that receives the Replace ID
6135 payload now sends the NICK_CHANGE notify type also in the file
6136 silcd/packet_receive.c
6138 * Changed WHOIS and IDENTIFY command to support the maximum amount
6139 of arguments defined in protocol specs (3328 arguments). This
6140 fixed a bug that caused problems when there were more than three
6143 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Added extra parameter, command identifier, to the
6146 silc_client_send_command so that explicit command identifier
6149 Changed that ID list routines uses specific command identifier
6150 when sending WHOIS/IDENTIFY requests to the server so that they
6151 can be identified when the reply comes back.
6153 Affected files lib/silcclient/command.[ch],
6154 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6156 * Added `sender' argument to silc_server_packet_send_to_channel
6157 to indicaet the sender who originally sent the packet to us
6158 that we are now re-sending. Ignored if NULL. Affected file
6159 silcd/packet_send.[ch].
6161 * Added some server statistics support in silcd/server_internal.h
6162 SilcServerStatistics structure and around the server code. Also
6163 send some nice statistics information when client is connecting
6166 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Fixed channel ID decoding in server's JOIN command reply in
6169 silcd/command_reply.c
6171 * Fixed braodcasting of replace ID payload to not to send it if
6172 we are standalone server in silcd/packet_receive.c.
6174 * Fixed all channel message sending routines to not to send
6175 packets to clients that has router set, since they are routed
6176 separately in the same function earlier. Affects file
6177 silcd/packet_send.c and all channel packet sending functions.
6179 * In USERS reply, res_argv[i] are not allocated, the table
6180 is allocated. Thus changed that free the table, not its
6183 * In server's whois_check and identify_check if the client is
6184 locally connected do not send any WHOIS commands - they are not
6187 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Fixed some minor bugs in client when sending WHOIS command. The
6190 arguments was in wrong order.
6192 * Removed statis function add_to_channel from server in
6193 silcd/command.c that was previously used with the joining but
6196 * Tested USERS command in router environment successfully with two
6197 routers, two servers and two clients.
6199 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Reorganized the USERS command and command reply in client library
6202 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6203 When the command is given by user we register a pending command
6204 callback that will reprocess the command after the reply has been
6205 received from the server. When reprocessing the packet we then
6206 display the information. Thus, the USERS information is displayed
6207 now in the command callback instead of in the command reply
6208 callback. The processing of the command is same as previously
6209 when server has sent the command reply in the JOINing process.
6211 * Added to USERS command in silcd/command_reply.c to join the client,
6212 we didn't use to know about, to the channel after we've created
6213 a client entry for it. Also, for clienet we did know already still
6214 check whether it is on the channel or not and add it if not.
6216 * Removed silc_server_command_join_notify as the function and its
6219 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Changed the client's pending command handling to the same as the
6222 server's pending command handling. It is also now possible to
6223 execute command reply functions from other command reply
6224 function as the function callbacks for commands and command
6225 replies are one and same. The pending commands are not static
6226 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6227 in client connection context. Thus, pending commands are server
6228 connection specific as it is convenient.
6230 Changed the function silc_client_command_pending and
6231 silc_client_command_pending_del and added new function
6232 silc_client_command_pending_check. Removed the
6233 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6236 * Added cmd_ident, current command identifier, to the client
6237 connection context in lib/silcclient/client.h to keep track on
6238 command identifiers used in command sending. Client's command reply
6239 function handling now supports the mandatory command identifiers.
6241 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6242 funtions in client to fully support pending command callbacks.
6244 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6245 as one of the arguments to the application in the command reply
6248 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6249 before first releasing SILC but came back. Now it is removed again
6250 and should come back nomore. The FORWARDED flag was used only
6251 by the JOINing procedure by forwarding the command packet to router.
6252 Now, the JOINing procedure has been changed to more generic (due
6253 to various router environment issues) and FORWARDED is not needed
6254 anymore for anything. The protocol specification is yet to be
6257 Now, removed silc_server_packet_forward from server and the flag
6258 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6260 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Renamed NAMES command to USERS command. The NAMES was named that
6263 due to historical reasons. Now it is renamed. Also, rewrote
6264 parts of the USERS command. The nickname list is not sent anymore
6265 by the server. Only Client ID and mode lists are sent in the USERS
6266 command. Changed this also to the protocol specification.
6268 The client now resolves the names and stuff after it receives
6269 the USERS list from the server when joining to the channel.
6271 * WHOIS and IDENTIFY commands has been changed to support multiple
6272 Client ID's per command. One can now search for multiple users
6273 in the network by sending only one WHOIS or IDENTIFY command.
6274 Changed the code and the protocol specifications.
6276 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6277 uses silc_server_command_whois_parse to parse the request. */
6279 * If normal server, do not parse the WHOIS and IDENTIFY requests
6280 before sending it to the router. Saves some time.
6282 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Fixed JOIN command on client library. Wrong number of arguments
6285 used to crash the client.
6287 * Added silc_server_channel_has_global function to check whether
6288 channel has global users or not.
6290 * Added silc_server_channel_has_local function to check whether channel
6291 has locally connected clients on the channel.
6293 * The silc_server_remove_from_one_channel now checks whether the
6294 channel has global users or not after given client was removed from
6295 the channel. It also checks whether the channel has local clients
6296 on the channel anymore. If it does not have then the channel entry
6297 is removed as it is not needed anymore.
6299 * The silc_server_notify now checks on JOIN notify whether the joining
6300 client is one of locally connected or global. If it is global then
6301 the channel has now global users on the channel and that is marked
6302 to the channel entry. Also, it now saves the global client to
6303 global list who is joining and JOINs it to the channel. This is
6304 for normal server, that is.
6306 Changed silc_server_send_notify_on_channel,
6307 silc_server_packet_relay_to_channel and
6308 silc_server_packet_send_to_channel check if we are normal server
6309 and client has router set (ie. global client) do not send the
6310 message to that client, as it is already routed to our router.
6312 * Implemented LEAVE notify type handling in silc_server_notify
6315 * Tested LEAVE command in router environment successfully. Tested
6316 with two routers, two servers and two clients.
6320 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6322 * Implemented SIGNOFF notify type handling in silc_server_notify
6325 * silc_server_remove_id now removes the client entry from all channels
6326 it has joined and thusly sends SIGNOFF notify type.
6328 * Rewrote the NAMES list generation in server by removing two excess
6329 loops. The lists are created now inside one loop.
6331 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * silc_server_remove_channel_user checks now also global list
6334 for channel and client.
6336 * silc_server_new_channel_user checks now both local and global
6337 list for channel and client. Fixed a bug in client id decoding.
6338 Used to decode wrong buffer.
6340 * silc_server_channel_message checks now both local and global
6341 list for channel entry.
6343 * Tested channel joining (hence JOIN) in router environment
6344 successfully. Tested with two routers, two servers and two
6347 * Tested channel message sending in router environment successfully.
6349 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Added silc_server_save_channel_key into server.[ch] to save the
6352 received channel key in Channel Key payload processing. It is
6353 also used in JOIN command reply handling.
6355 Equivalent function silc_client_save_channel_key added into
6356 client.[ch] into client library.
6358 * Changed JOIN command reply to send information whether the channel
6359 was created or not (is existing already) and the channel key
6360 payload. Changed protocol specs accordingly.
6362 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6363 the request was sent by ID and not by nickname. Crashed on
6366 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6368 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6369 now correctly save the received data.
6371 * silc_server_free_sock_user_data now notifies routers in the
6372 network about entities leaving the network.
6374 At the same time implemented functions silc_server_remove_id
6375 and silc_server_send_remove_id to receive and send REMOVE_ID
6376 packets. The packet is used to notify routers in the network
6377 about leaving entities. The ID removed will become invalid in
6380 * Added function silc_idlist_del_server into server. Removes and
6381 free's server entry from ID list.
6383 * silc_server_private_message function now checks, if we are router,
6384 that the destination ID really is valid ID, naturally.
6386 * In router when NEW_ID packet is received (for new client) the
6387 hash of the Client ID is saved in the ID Cache but the
6388 client->nickname is set to NULL, instead of putting the hash
6391 IDENTIFY command now also checks that client->nickname must be
6392 valid. If it is not if will request the data from the server who
6393 owns the client. Added new function
6394 silc_server_command_identify_check.
6396 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6397 to set the command to already allocated Command Payload.
6399 * Tested private message sending in router environment with two
6400 routers, two servers and two clients. Fixed minor bugs and now
6403 * Fixed segfault from client's NAMES command. Used to crash if
6406 * Forwarded packets must not be routed even if it is not destined
6407 to the receiver. Changed server code comply with this.
6409 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added `require_reverse_mapping' boolean value to ServerParams
6412 structure. If TRUE (not default) the server will require that
6413 the connecting host has fully qualified domain name.
6415 If the reverse mapping is not required and hostname could not be
6416 found the IP address is used as hostname.
6418 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Implemented version string checking to both client and server.
6421 The check is incomplete currently due to the abnormal version
6422 strings used in development version of SILC.
6424 * Changed all command functions in server to use the new
6427 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Changed char *data to unsigned char *data in ID Cache system to
6430 support binary data as ID Cache data. Changed code to support
6431 binary data in lib/silccore/idcache.c.
6433 * Renamed silc_server_packet_relay_command_reply to
6434 silc_server_command_reply as it is normal packet receiving
6435 function. Rewrote the function to accept command replys for
6436 servers and not only for clients.
6438 * Mark remote router always as registered server if we are connecting
6439 to it. Otherwise, commands sent by the router to us are ignored.
6441 * All ID List find routines now returns the ID Cache Entry pointer
6442 as well if requested.
6444 * WHOIS command works now in router environment, tested with two
6445 routers, two servers and two clients.
6447 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6448 in router environment (as it is almost equivalent to WHOIS) but
6449 hasn't been tested thoroughly. Added new functions:
6451 silc_server_command_identify_parse
6452 silc_server_command_identify_send_reply
6453 silc_server_command_identify_from_client
6454 silc_server_command_identify_from_server
6456 * Disabled route cache adding because adding two different ID's with
6457 same IP replaces the old cache entry thus giving wrong route.
6458 The entry->router->connection is always the fastest route anyway
6459 so route cache may not be needed. Of course, new routes maybe
6460 established after receiving the ID when the entry->router->connection
6461 might not be anymore the most optimal.
6463 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Add route cache for received ID for fast routing.
6467 * Added silc_server_packet_route to route received packet on router
6468 that is not destined to us.
6470 * Renamed silc_server_get_route to silc_server_route_get.
6472 * Added id_string and id_string_len fields into SilcServer to
6473 include encoded ServerID for fast comparing without excess
6474 encoding of the ID's.
6476 * Cleaned up WHOIS command on server side. Added following static
6479 silc_server_command_whois_parse
6480 silc_server_command_whois_check
6481 silc_server_command_whois_send_reply
6482 silc_server_command_whois_from_client
6483 silc_server_command_whois_from_server
6485 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6486 arguments in command replies. All command functions should be
6487 updated to use this macro.
6489 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Minor typo fixes on command reply handling on server.
6493 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Added silc_server_command_add_to_channel internal routine to add
6496 the client to the channel after router has created the channel and
6497 sent command reply to the server.
6499 * Added generic silc_server_send_command to send any command from
6502 * Use static buffer with ID rendering instead of duplicating data.
6504 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Fixed a channel user mode bug when joining to a channel server gave
6507 everybody channel founder rights, oops.
6509 * We mark ourselves as the router of the incoming server connection
6510 if we are router ourselves. This way we can check in some packet
6511 sending functions whether it is locally connected server. For
6512 incoming router connections we put NULL.
6514 * For router sending packets locally means now always sending the
6515 packet cell wide; to local clients and local servers. For normal
6516 server sending packet locally means sending it to only local
6519 * Fixed the JOIN command to really work in router environment. If the
6520 channel is created it is always created by the router. Router is
6521 also responsible of making the initial joining to the channel,
6522 sending JOIN notify to the sending server and distributing
6523 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6524 does not exist server doesn't do anything else but forward the
6525 command to the router which performs everything.
6527 * Added silc_server_send_channel_key function to send the Channel Key
6530 * Added silc_server_create_channel_key to create new channel key. The
6531 channel key is now re-generated everytime someone joins or leaves
6532 a channel, as protocol dictates. Note: channel->key_len is the
6535 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6538 packet_receive.[ch] to separate packet sending and receiving
6539 routines. The server.[ch] now includes everything else including
6540 actual packet processing (writing and reading data) and other
6543 Renamed silc_server_private_message_send_internal to
6544 silc_server_send_private_message. The routine is still though
6545 used only to relay private messages as server does not send
6546 private messages itself.
6548 Renamed silc_server_new_channel to silc_server_create_new_channel
6549 and added new function sicl_server_new_channel that handles the
6550 incoming New Channel packet. Added also new sending function
6551 silc_server_send_new_channel to send New Channel Payload.
6553 * Added new function silc_server_notify to process incoming notify
6554 packet to the server/router. Server may then relay the notify
6555 to clients if needed.
6557 * Added new function silc_server_new_channel_user to process incoming
6558 New Channel User packet. Router will redistribute the packet and
6559 send JOIN notify to its local clients and locally connected servers
6560 if needed. Normal server will send JOIN notify to its local client
6561 on same channel when received this packet. Added also corresponding
6562 sending function silc_server_send_new_channel_user to sent the
6565 * Added boolean route argument to send_notif_to_channel and
6566 packet_send_to_channel functions to attempt to route the packet
6567 if it is TRUE and send only locally if it is FALSE.
6569 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * silc_server_replace_id now broadcasts the received replace ID
6572 packet if it is not broadcast packet already. The router must
6573 broadcast to inform other routers about changed ID.
6575 * Added backpointer to server's router into SilcServer context in
6576 silcd/server_internal.h.
6578 * Fixed silc_server_packet_broadcast to send correct broadcast
6581 * The channel key is now distributed to the local client as soon
6582 as it is received from the router (in router environment) so that
6583 no other packet may be sent for the channel until client has
6586 * silc_server_remove_channel_user now broadcasts the received
6587 Remove Channel User packet if it is not broadcast packet already.
6588 The router must broadcast to inform other routers about removed
6591 * Added users field into SilcPacketContext that is a reference count
6592 of the context. One can increase the reference count by calling
6593 silc_packet_context_dup which is now changed to just increase the
6594 reference count instead of duplicating the data. The reference
6595 count is decresed by calling silc_packet_context_free that will
6596 free the data after the reference count hits zero.
6598 For now on the packet context and everything allocated into it
6599 (including the raw packet from network) must be freed by calling
6600 the new silc_packet_context_free function. Added also new function
6601 silc_packet_context_alloc that must be used now to allocate the
6602 context. This also means that if a routine is asynchronous from
6603 silc_[client/server]_packet_parse_type the packet context must
6604 be duplicated by calling silc_packet_context_dup. Otherwise it
6605 gets free'd after silc_[client/server]_packet_parse_type returns.
6606 Also, one must remember that if packet is duplicated then its
6607 reference count must be decresed by calling the free function as
6608 many times as it was duplicated.
6610 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6611 from both client and server.
6613 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Made joining to a channel working in router environment.
6617 * Cleaned up JOIN command on server side and create function
6618 silc_server_command_join_channel internal routine to make the
6621 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Changed silc_command_pending list to SilcDList. Also, added
6624 `ident' field to SilcServerCommandPending structure to identify
6625 the reply and to call correct callback.
6627 Added silc_server_command_pending_check function to replace the
6628 corresnponding macro. The silc_command_pending list is not
6631 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6632 to set identifier to previously allocated Command Payload. It
6633 is used to set identifier for command when resending Command
6636 * Added silc_command_payload_encode_payload to encode Command
6637 Payload buffer from SilcCommandPayload structure.
6639 * Added silc_argument_payload_encode_payload to encode Argument
6640 payload buffer from SilcArgumentPayload structure.
6642 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * Changed WHOIS command to support router connection on server side.
6645 The whois request is always sent to router unless the server is
6646 standalone server. After server has received the reply from the
6647 router will it send the reply to the client.
6649 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6650 broadcast received broadcast packet. The function is used only
6651 by router. The broadcast packet is always sent to the router's
6654 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6655 render given ID to printable string, for log files for example.
6657 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Made basic router to router connections working. At least they
6660 can now connect to each other but nothing really works the way
6661 they are supposed - yet.
6663 * Added new initiator token to RouterConnection configuration
6664 file in silcd/serverconfig.[ch]. It is used to tell whether we
6665 are the initiator to the remote router or whether we'll expect
6666 the other end to connect.
6668 * Moved registering of listener task to silc_server_init, hence
6669 the server starts listenning as soon as it is run, even if it
6670 does not have connections to other routers. Let's see how well
6673 * Changed default connection retry timeouts for more suitable in
6676 * Removed cipher and such arguments from silc_idlist_add_client
6677 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6678 Added new function silc_idlist_add_data to add the keys and stuff
6681 * Added SilcIDListData structure and added it to SilcClientEntry
6682 and SilcServerEntry as their first field in the structure. This
6683 way we can explicitly cast the ID entries to the SilcIDListData
6684 structure and get common data for the entries. In past, we had
6685 to first check what type of connection it is and then cast it to
6686 correct ID entry type. Now, we can directly cast the opaque
6687 pointer to the SilcIDListData (no matter what ID entry it actually
6688 is) and get the data needed.
6690 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6693 in some circumstances even if threre were timeout tasks, though not
6694 IO tasks, but tasks anyway. Now fixed.
6696 * Defined SilcServerConnection structure to hold connection specific
6697 stuff about directly connected servers and routers. The definition
6698 is currently in silcd/server_internal.h. I thought about having
6699 a bit more important role fro this struct but for now it is used
6700 only when connecting to other server (or router actually).
6702 * Added connecting retry support in server when connecting to
6703 router(s). The retry feature implement exponential backoff
6704 algorithm. Also, added SilcServerParams structure to hold default
6705 parameters for server. For now, it include these retry settings
6706 and are hard coded. After server is moded to be as Silc Server
6707 Library this structure will be more important.
6709 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Changed client librarys channel->clients table to SilcList and
6712 changed code accordingly.
6714 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Changed client's channel table to SilcList and changed code
6717 accordingly. Also changed SilcChannelClientEntry to include back-
6718 pointer to the channel so that client entry can use that structure
6719 as list as well and we have fast cross-reference to the channel.
6720 This change dramatically decreased the complexity of channel
6721 handling with client entry and vice versa (removed one extra
6722 loop when searching for channel entry from many functions).
6724 * Changed server->sim from table to SilcDList and changed code
6727 * NAMES command can now be used from user interface. It will show
6728 the user list on the channel, neatly.
6730 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6731 Code now saves realname of the user if it becomes available.
6733 * Renamed configure.in to configure.in.pre and made ./prepare
6734 script to automatically add correct version string to
6735 configure.in which it creates from configure.in.pre.
6737 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * NAMES command reply now shows users mode with the nickname when
6742 * Moved silc_client_ch[u]mode[_char] functions from
6743 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6744 place sucks, they are utility functions and should be in some
6747 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6749 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6752 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added TRQ (efficient deque and list library) into lib/trq. This is
6757 a very good list library that is currently used in the SILC. Defined
6758 SilcList API over the library because I didn't like the API very
6759 much. See lib/trq/silclist.h for the API and examples of how to
6760 use the API. Fixed various places in the code to use the new
6761 SilcList API. The SilcList is meant for lists that has a structure
6762 already defined as a list. It is not suitable to add just some
6763 context to the list (in TRQ, the context is the list actually).
6765 So, I defined SilcDList that can be used for the purpose where
6766 predefined list structure does not exit. This can be used as
6767 such list. Now some context just can be added to the SilcDList.
6768 Currently this list is not used in the SILC just yet, though there
6769 are a lot places where this can replace dynamically allocated
6770 tables and I will fix these places, later, to use SilcDList.
6771 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6772 and use TRQ internally).
6774 Also fixed some annoying warning messages that the original TRQ
6775 code generated. Also minor changes to TRQ's Makefile.in.
6777 * Added support for querying by Client ID to both WHOIS and
6778 IDENTIFY commands into server, as required by the protocol.
6780 * Removed method function pointers from SilcBuffer structure. They
6781 weren't used to anything and just increased the context size for
6782 no good reason. This change also made silc_buffer_alloc and
6783 silc_buffer_free functions inline functions.
6785 * Disabled command flooding detection support until it's fixed so
6786 that it accepts commands in but does not execute them more than once
6789 * Added silc_net_localhost(), to return local hostname, into
6790 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6791 that must be initialized before calling silc_client_init.
6793 * Added new function: silc_server_send_notify_on_channels to send
6794 notify messages to all channels client has joined. It is assured
6795 that the message is sent only once per client.
6797 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6798 lib/silcutil/silcutil.[ch] as silc_format function. The new
6799 function is generic and is used by server as well, not only by
6800 the logging routines.
6802 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6803 the provided version string was not acceptable. Added new function:
6804 silc_ske_check_version into lib/silcske/silcske.h. The function
6805 must be implemented by the application (client or server) and it
6806 does not reside in the SKE library. The function checks the version
6807 string remote end sent.
6809 * Added back pointers (to opaque context and to SilcSocketConnection)
6810 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6812 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6813 duplicate packet context structure.
6815 * Changed `notify' client operation to send same arguments as client
6816 receives from server except for ID's. ID's are mapped to correct
6817 ID entry and that is returned. Also, if channel entry is not sent
6818 by server but the notify is for channel the channel entry is sent
6819 to application (otherwise application doesn't know that it is for
6820 channel (library gets it from packet's Destination ID)).
6822 * Added silc_client_remove_from_channels into client library to
6823 remove a client from all channels it has joined to. Used when
6824 received SIGNOFF notify from server. Added also new function
6825 silc_client_replace_from_channels to replace old ID entry with
6826 new ID entry on all channels. Used when received NICK_CHANGE
6829 * Fixed ID Cache list handling in silc_idlist_get_client in
6830 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6831 to get (or query) client by ID.
6833 * Updated TODO list.
6835 * Added connection authentication status message defined by the
6836 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6837 support for these into the code in client and server side.
6839 * Added generic function silc_client_send_command to send any command
6840 with variable argument list. Application should use this function
6841 to send commands if the command functions provided by the library
6842 does not suite for the application's user interface needs.
6844 * Added new `failure' client operation. Application is notified about
6845 received failure packet if client is executing a protocol. In this
6846 case the protocol's execution has failed.
6848 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6849 is required by the protocol.
6851 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6852 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6855 * Added status flag to SilcSKE object to indicate realtime status
6856 of the SKE protocol.
6858 * Application receives now exactly same command reply arguments as
6859 the library receives from server. However, if ID is received the
6860 corresponding ID entry is returned to the application (eg. Client
6861 ID is mapped to correct SilcClientEntry entry and that is returned).
6862 Changed command_reply client operation due to this change.
6864 * Changed all ID's in commands and in command replys as ID Payloads.
6865 Change affected both client and server side codes.
6867 All ID's sent in SILC network (with execption of ID's in SILC
6868 Packet header) are sent in ID Payload to support variable length
6871 * Server now notifies nick changes and notifies all clients on
6872 the channels about the new nickname (about the new Client ID,
6875 * Implemented CMODE command to change channel modes. Supports all
6876 channel modes defined by the protocol specs except ban and invite
6877 lists. (Also, private channel key mode is supported but support for
6878 setting private channel key in client is missing, thus, this mode
6879 has no effect on client side (except that server requires that the
6880 client uses private channel key and normal channel traffic does not
6883 Also, invite mode works per se, but INVITE command does not work
6884 yet correctly, so you can set channel as invite only channel but
6885 inviting clients to the channel does not work (it is yet to be
6886 thought what's the best way to do it).
6888 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6889 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6890 Implemented CUMODE command to change user's mode on the channel.
6891 Supports all modes defined by the protocol specs.
6893 * Added NAMES command reply to return users modes on the channel.
6895 * Removed unnecessary and slow ciphers from lib/silccrypt.
6897 * Set SO_KEEPALIVE option to connection sockets by default.
6899 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6901 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6902 redefined the Notify Payload into protocol specs.
6904 * Added silc_id_payload_parse_id to get ID directly from raw
6907 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6910 accept searching by Client ID as well.
6912 * Added support for LEAVE and SIGNOFF notify types in client library.
6914 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6915 to parse ID Payload from raw data.
6917 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Added flags parameter into silc_ske_assemble_security_properties
6920 function in lib/silcske/silcske.[ch].
6922 * Changed notify client operation to fit better for notify messages
6923 sent by server. The notify payload received from server is now
6924 passed to the application (after parsing it to SilcNotifyPayload).
6925 It is application's responsibility to retrieve the arguments
6926 from the payload and show the message the way it wants. The message
6927 sent by server is implementation specific.
6929 * Changed public keys to comply with the protocol specification.
6930 Old public keys are not supported anymore and are not compatible.
6932 * Removed nickname from Channel Payload as the latest draft removed
6933 it. The client must resolve the nickname from the NAMES command
6934 reply received when it joined the channel.
6936 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6938 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Fixed some errors in protocol specification drafts.
6942 * Created lib/silccore/silcnotify.c to implement Notify Payload
6943 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6944 generic payloads described by protocol specifications. The file
6945 includes implementations for ID Payload and Argument Payload.
6947 * Changed Command Payload implementation to use the new Argument
6948 Payload. Changed command_xxxx_payload to command_payload_xxxx
6949 to comply with SILC coding conventions.
6951 * Added suppport for Argument Payload handling in Notify Payload
6952 implementation as protocol requires it. Added the new support
6953 into server and client lib as well.
6955 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Added support for multiple nicknames on same channel. [n] is
6958 added locally to the nickname if there are more than one same
6959 nicknames on the channel.
6961 * Server now sends all nicknames that matched WHOIS request.
6962 Client also shows the list received from server.
6964 * Added TOPIC command to client side. User can now set and show
6965 current topic on channel.
6967 * Added MOTD command to client and server. Also, server sends the
6968 motd when client connects to the server.
6970 * Changed version strings to comply ISO 8601.
6972 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Fixed protocol error handling in client library. It should now
6975 cope even if the SKE fails for some reason.
6977 * Made new protocol specification drafts for submitting to IETF.
6979 * Implemented TOPIC command to server in silcd/command.c.
6981 * Added two new notify types into lib/silccore/silcnotify.h:
6982 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6983 notify nickname change and topic setting/change on a channel.
6985 * API change of command_reply operation in client library. The
6986 application gets now the status type received from server as well.
6988 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6992 * Cras fixed and optimized the packet handling even further and
6993 it should work now. Minor change to the prototype of function
6994 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6996 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added new function into lib/silcutil/silcschedule.[ch]:
6999 silc_schedule_with_fd to select() a specified fd. The function
7000 returns after timeout expires or data arrives or goes. The
7001 function is used by packet routines to wait that all data is
7002 received from network.
7004 * Fixed data reading from network in lib/silccore/silcpacket.c.
7005 The code now assures that all data is read from the fd and then
7006 continues packet processing. This was a bug fix since the code
7007 used to drop some data in some circumstances.
7009 * Added new function into lib/silcclient/client.[ch]:
7010 silc_client_start_key_exchange to start key exchange after
7011 connection has been established to server. The code internally
7012 now uses this funtion but its main purpose was to provide it
7013 for applications that perform their own connecting. After
7014 application has created a connection it merely calls this
7015 function to start the key exchange between client and server.
7016 The library takes care of everything else after that.
7018 Updated also lib/silcclient/README to explain the usage of
7021 * Do not send to application information that connection has
7022 been established. Application gets notified it by connect
7025 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Applied cras's patch to add silc_schedule_one function. The
7028 function runs scheduler once and returns.
7030 * Fixed the scheduler after cras messed it up. The timeout
7031 handling works now as it's supposed to work.
7033 * Added into lib/silccore/ silcnotify.h to include notify
7034 message types support. Changed silc_server_send_notify*
7035 functions, in server.[ch], to support those new notify types.
7036 Added the support for the notify types into client library,
7037 as well. Added new notify client operation into ops.h in
7040 * Changed silc_server_packet_send_to_channel to send normal
7041 packets instead of just channel message packets. The function
7042 is now used to send the notify packets to channels. It is not
7043 used to send channel message packets anymore, as server never
7046 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7047 va_arg()s as it seems to require it nowadays. I guess, if SILC
7048 is compiled with older va_arg() the new code should work anyway.
7050 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Splitted core library. Core library (lib/silccore) includes
7053 now only SILC protocol specific core (and common) components.
7054 Created new utility library (lib/silcutil) that includes more
7055 generic purpose stuff. The stuff for util library was taken
7056 from the old core library. This was minor and easy split.
7058 * Created SILC Client Library (lib/silcclient) that includes
7059 implementation of the SILC client without user interface. This
7060 was major move from silc/ directory. The code has been changed
7061 so that it is transparent towards the user interface. The
7062 silc/ directory includes now the same user interface as before
7063 and it uses the new client library. Read lib/silcclient/README.
7064 Basicly, the client library performs everything else related
7065 to SILC except user interface handling. Also, configuration
7066 files are considered to be part of user interface and library
7067 does not handle them.
7069 This change also changed a lot of structures, function naming etc.
7070 Most important change was that SilcClientWindow object was
7071 renamed to SilcClientConnection in the client library. Created
7072 also new file lib/silcclient/ops.h. Also added new files
7073 silc/local_command.[ch] and silc/client_ops.[ch].
7075 All these changes were made to make it easier for user interface
7076 designers to create what ever user interface for the SILC client
7079 It is also expected that the server will be moved to lib
7080 directory as well and SILC Server Library will be created;
7081 sometimes in the future.
7083 * Removed Local commands from lib/silccore/silccommand.h as
7084 they are application specific and new client library does not
7085 handle any of those anymore.
7087 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7088 old client implementation in silc/.
7090 * Added support for callback functions in SILC_LOG_* macros.
7091 Application can now set its own callbacks that will be called
7092 instead of using the default functions that will always print
7093 the debug messages to stderr (or stdout). Also, debugging can
7094 now be disabled by setting silc_debug to FALSE and re-enabled by
7095 setting it to TRUE. Note, that logging will still work even
7096 if debugging is disabled.
7098 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7099 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7100 silc_log_reset_debug_callbacks.
7102 * To enable debugging in silc client one must give now -d
7103 option on command line.
7105 * Changed silc_schedule_init to automatically allocate task queues
7106 if they are not allocated before calling it.
7108 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7110 * Added GMP 3.1 into math library.
7112 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7115 a channel in SILC network. The packet is used by servers and
7116 routers to notify other routers that user has left a channel.
7117 This little feature was missing until now. Added the feature
7118 to protocol specification as well.
7120 Added functions: silc_server_send_remove_channel_user and
7121 silc_server_remove_channel_user into server.[ch].
7123 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7124 lib/silccore/silcpacket.h. However, they are not implemented
7127 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Fixed joining to a channel and sending channel messages
7130 between server and router. The channel message sending should
7131 now work inside a cell.
7133 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7135 * Fixed the private message sending between server and router.
7136 The private message sending should now work inside a cell.
7138 * Added silc_server_replace_id into server.[ch] to replace
7139 existing ID in the SILC network.
7141 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7142 and silc_idlist_replace_server_id into idlist.[ch] in server.
7144 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Fixed the server to server connections. Server can again now
7147 connect to router. Router to router connections probably does
7150 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added dynamic protocol registering support. Now protocols can
7153 registered and unregistered on the fly. Patch by cras.
7155 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7157 * Added lib/contrib directory to hold routines that some platforms
7158 don't have but are needed by SILC.
7160 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7161 into lin/contrib to provide getopt() and getopt_long() for
7162 those who don't have it.
7164 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Added AWAY command to client. When away message is set and
7167 client receives a private message packet the client automatically
7168 replies to the sender with the away message.
7170 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7171 bug seemed to be the cause of recent problems when compiling
7174 * Added version detection support to SKE protocol specification
7175 and added the new changes to the SKE implementation as well.
7176 There were other minor changes in the SKE protocol as well.
7178 Many changes in lib/silcske/silcske.[ch] and in
7179 lib/silcske/payload.[ch].
7181 * Added ^U functionality, clear input line. Patch from cras.
7183 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Mainly small bugfixes on core library. Fixed some debugging
7186 logging and buffer overflow in silclog.c.
7188 * Updated config.sub and config.guess on the distribution tree.
7190 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7192 * Added command lagging support in server. Client may execute
7193 commands now only once in two seconds.
7195 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Optimized packet reception. MAC computation and checking is now
7198 also more optimized. A lot previously duplicated code is now
7199 used as generic by both client and server.
7201 * Fixed key pair generation in clientutil.c
7203 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Added into lib/silccore/silcbufutil.[ch] new function;
7206 silc_buffer_realloc.
7208 * Moved generic packet sending/encryption functions to
7209 lib/silccore/silcpacket.[ch] from client and server. Some
7210 rewriting of the functions.
7212 * Moved all generic packet reception/decryption functions to
7213 lib/silccore/silcpacket.[ch] from client and server. The
7214 packet processing is now much cleaner in both client and server.
7215 These were major changes in both client and server.
7217 * Created many common functions in server to do packet sending.
7218 Previously code were duplicated a lot, this has been removed
7221 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Rewrote major parts of the ID cache system. Don't know
7224 whether it is better now or not but at least the API is more
7227 * Major rewrite on ID cache stuff on client because of the ID
7228 cache API changes. Added idlist.c to client.
7230 * Also major rewrite on ID cache stuff on server as well.
7231 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7232 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7233 in hand, instead they are all put into the ID cache system now.
7234 All server_idlist_* routines uses ID cache now instead of
7235 traversing its own lists (those lists does not exist anymore).
7236 SilcIDList though still exists. Also, SilcXXXEntry's are
7239 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Finally made the SKE implementation compliant to the protocol
7242 specification. All mp integers are now binary encoded as
7243 opposed being HEX encoded.
7245 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7248 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7249 functions: silc_[encode/decode]_pem. Also added function
7250 silc_encode_pem_file to PEM encode with newlines ('\n') for
7253 * SILC public keys are now encoded either PEM or binary. Same
7254 option is for private keys as well. By default private keys
7255 are binary encoded and public keys PEM encoded. Silly HEX
7256 encoding were removed.
7258 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7259 function to create fingerprints.
7261 * Fixed a bug in SHA1; does not change the original data anymore.
7263 * Partly implemented INFO command on client and server side.
7264 Fixed CLEAR command. Changes to SERVER command; show current
7265 server(s) when giving command without arguments. Added
7266 VERSION command to client.
7268 * Added check to server that unregistered connections cannot
7269 execute commands (unless it is specificly allowed).
7271 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Fixed screen refresh.
7275 * Fixed channel joining bug from client. On some circumstances
7276 client tried to join to a channel it had already joined.
7278 * Added public key verification process into client's protocol.c.
7279 The client now verifies the public key from user and saves
7280 it into ~./silc/serverkeys/ directory.
7282 Added into: clientutil.[ch]: silc_client_verify_server_key.
7284 * Changed SKE protocol's silc_ske_initiator_finish function
7285 to accept callback function that verifies the received public
7286 key. Removed old silc_ske_verify_public_key function.
7288 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7291 silc_pkcs_private_key[_data]_set.
7293 * Made the password and public authentication more cleaner in
7294 server's protocol.c.
7296 * Removed historic and obsolete protocol `channel_auth' from
7297 both client and server.
7299 * Removed wrong way of sending command status messages from
7300 server to client in server's command.c. The old way violated
7301 protocol specification.
7303 Changes to silccore/silccommand.[ch]: removed
7304 silc_command_encode_status_payload -> not needed anymore,
7305 changed silc_command_encode_payload_va to accept extra
7306 argument on variable argument list. The argument type must
7307 now be provided to the function. Also, added new function:
7308 silc_command_encode_reply_payload_va which is same as
7309 normal command_encode_payload_va except command status type
7310 is provided as extra argument.
7312 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Added ~./silc directory handling. The directory includes the
7315 public and private keys for the client.
7317 Added silc_client_check_silc_dir, silc_client_create_identifier
7318 and silc_client_load_keys.
7320 * Implemented SILC protocol compliant public key. Added public
7321 and private key saving to and loading from files.
7323 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7324 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7325 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7326 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7327 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7329 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7330 silc_pkcs_load_[public/private]_key.
7332 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Added silc_server_get_route (route.[ch]) to get connection
7335 data for the fastest route for given ID.
7337 * Implemented INVITE command on client and server. The command
7338 were re-defined in the SILC Protocol Specification and the
7339 implementation now complies with the specification.
7341 * Implemented PING command on client and server.
7343 * Implemented NAMES command on client and server. The server side
7344 supports currently only normal server not router server yet.
7345 Some changes to NAMES definition in SILC protocol specification.
7347 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Implemented LEAVE command on client and server.
7351 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7352 again. This change was made to the protocol as well. Server
7353 should not violate the protocol specification anymore.
7355 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7358 was tested. SOCKS4 was not but should work anyway.
