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

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

210 client_entry->channels hash table everytime nick is changed.
211 Affected file lib/silcclient/client.c.
213 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
215 * ROBOdoc documented the lib/silcske/silcske.h, and improved
216 the SKE interface a bit.
218 * Fixed padding problem in PKCS#1. The padding was not actually
219 random since the random number generator was used incorrectly.
220 This security bug affects only when encrypting with PKCS#1, and
221 it is not currently used at all in SILC. SILC only use signing
222 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
224 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

290 * Added new configuration options and blocks:
291 keepalive_secs, reconnect_count, reconnect_interval,
292 reconnect_interval_max, reconnect_keep_trying and
293 require_reverser_lookup. Added ConnectionParam block, and
294 implemented the connection parameters when connecting as
295 initiator and when accepting connections as responder.

298 whether given configuration value has been given already.
300 Affected files silcd/serverconfig.[c], server.[c].
302 * Splitted the doc/example_silcd.conf.in. Separated the crypto
303 algorithm parts and created new file silcalgs.conf, that
304 is now included from the example_silcd.conf.in.
306 * Optimized the silc_server_connect_to_router_second to take
307 the connection configuration object from the SilcServerConnection
308 object instead of finding it during the connecting phase.
309 Added the configuration object to SilcServerConnection struct.
310 Affected files silcd/server_internal.h, server.c.
312 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

441 * Fixed a bug in hash table internal routine for traversing
442 the table with foreach callback. The current entry may
443 become invalid in the callback but it was referenced after
444 the callback returned.
446 Do not allow auto rehashing of hash table during the
447 silc_hash_table_foreach operation, for same reasons as it is
448 not allowed for SilcHashTableList. Affected files are
449 lib/silcutil/silchashtable.[ch].
451 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

471 SilcClientEntry, and changed the SilcChannelEntry's
472 users list to SilcHashTable. The affected files are
473 lib/silcclient/idlist.[ch].
475 * Fixed a bug in hash table tarversing. While the hash table
476 is traversed with SilcHashTableList the table must not be
477 rehashed. It is now guaranteed that auto rehashable tables
478 are not rehashed while tarversing the list. Also defined that
479 silc_hash_table_rehash must not be called while tarversing
480 the table. Added function silc_hash_table_list_reset that must
481 be called after the tarversing is over. The affected files are
482 lib/silcutil/silchashtable.[ch].
484 * Changed all hash table traversing to call the new
485 silc_hash_table_list_reset in server and in client library.
487 * Added function silc_client_on_channel to return the
488 SilcChannelUser entry if the specified client entry is joined
489 on the specified channel. This is exported to application as
490 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

496 not only if !cmd->pending. Affected file silcd/command.c.
498 * Fixed the WHOWAS command's reply sending to support the
499 lists correctly. Affected file silcd/command.c.
501 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
503 * When sending JOIN command to router for processing the
504 sender's old command identifier was not saved back to the
505 sender's command context, fixed now. The affected file is
508 * Create the key in JOIN command of the router did not return
509 the channel key, added check for this. Affected file is
512 * Fixed a channel ID update bug in JOIN command reply. Do
513 not directly upgrade the ID but call the function
514 silc_idlist_replace_channel_id if the ID was changed.
515 Affected file silcd/command_reply.c.
517 * Fixed memory leaks from command calling if it would fail.
518 Affected file silcd/command.c.
520 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

530 * Removed TRQ from lib/trq, not needed anymore.
532 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
533 with server connections. Later this will be configurable
534 in config file after new config file is done. Affected file
537 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
539 * Fixed a crash in server related to channel announcements.
540 Affected file silcd/server.c.
542 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed memory leaks in silc_server_create_new_channel*
545 functions. Affected file silcd/server.c.
547 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
548 which ID was changed. This way the router will send the
549 user list for the channel again, and server won't be in
550 desync in some rare circumstances. Affected file is
551 silcd/packet_receive.c.
553 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
555 * Check for NULL socket pointer in the function
556 silc_server_packet_send_to_channel_real. Affected file
559 * Fixed the BAN notify handling to correctly remove ban
560 list. Affected file silcd/packet_receive.c.
562 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
564 * Fixed some header addition to Toolkit distribution in
565 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
567 * Added lib/silcclient/client_ops_example.h as an template
568 file for application programmers to quickly start using
569 the SilcClientOperation functions in their application.
570 Updated the lib/silcclient/README as well to tell about this
571 nice file made available.
573 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Call silc_server_remove_from_channels when removing client
576 entry when NO_SUCH_CLIENT_ID was received. Affected file
577 is silcd/command_reply.c.
579 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Added server & router operator statistics updating. Affected
582 file silcd/packet_receive.c and silcd/command.c.
584 * Fixed the SERVER_SIGNOFF notify handling on normal server
585 not to save the history information for clients. Same was
586 fixed earlier in remove_clients_by_server function, but not
587 here. Affected file silcd/packet_receive.c.
589 * Raised the default connection-retry count from 4 to 7 in
590 server. Affected file silcd/server.h.
592 * Cancel any possible reconnect timeouts when we start the
593 key exchange. Affected file silcd/server.c.
595 * Do not reconnect on connection failure when SCONNECT was
596 given. Affected files silcd/server.[ch].
598 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
600 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
602 * Fixed the NICK command to always give the unformatted
603 nickname to the one giving the NICK command. If unformatted
604 nickname is cached already it will be formatted and the
605 local entry will always get the unformatted nickname.
606 Affected file lib/silcclient/idlist.c.
608 * Fixed some double frees from client library commands.
609 Affected file is lib/silcclient/command.c.
611 * Fixed CUMODE command in server to assure that no one can
612 change founder's mode than the founder itself, there was a
613 little bug. Affected file silcd/command.c.
615 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
617 * Removed the SilcClientCommandDestructor from the client
618 libary, it is not needed anymore. Affected files are
619 lib/silcclient/silcapi.h, command[_reply].[ch],
620 client_notify, idlist.c.
622 * Fixed GETKEY command to first resolve client, and then
623 resolve the server only if the client was not found, instead
624 of resolving both at the same time. Affected file is
625 lib/silcclient/command.c.
627 * Added silc_client_start_key_exchange_cb and lookup the
628 remote hostname and IP address before starting the key
629 exchange with server. The affected file is
630 lib/silcclient/client.c.
632 * The server's public key is now saved using the IP address
633 of the server and not the servername for the filename.
634 The hostname public key filename is checked as an fall back
635 method if the IP address based filename is not found.
637 Fixed the GETKEY command to save the fetched server key
640 Print the remote server's hostname now when new key is
641 received during connection process. Affected file is
642 irssi/src/silc/core/client_ops.c.
644 * Return always our own public key to the client if it asks
645 for it with GETKEY command. Affected file silcd/command.c.
647 * Removed the use_auto_addr variable from default config
648 file since it was in wrong section. Affected file is
651 * Fixed TOPIC_CHANGE notification to not route it when it
652 was sent using silc_server_send_notify_to_channel function.
653 Affected file silcd/command.c.
655 * Fixed silc_server_send_notify_kicked to send the kicker's
656 Client ID also, it was missing. Affected files are
657 silcd/command.c, silcd/packet_send.[ch].
659 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Do not save client history information in SERVER_SIGNOFF.
662 Fixes the bug in normal server that it does not detect
663 the client becoming valid after the server becomes back
664 online. Affected file silcd/server_util.c.
666 * Added `sock_error' field into the SilcSocketConnection
667 context. When error occurs during socket operation (read
668 or write) the error is saved. Added also new function
669 silc_socket_get_error to return human readable socket error
670 message. Affected files are lib/silcutil/silcsockconn.[ch],
671 lib/silcutil/unix/silcunixsockconn.c, and
672 lib/silcutil/win32/silcwin32sockconn.c.
674 * The server now prints the socket error message in the
675 signoff for client. Affected file silcd/server.c.
677 * Fixed the `created' channel information sending from router
678 to server in JOIN command. Checks now whether the channel
679 really was created or not and set it according that.
681 Fixed the JOIN command to use the client entry's current
682 ID during the joining procedure instead of the one it sent
683 in the command (it is checked though), since it can change
684 between the packet processing and command processing, and
685 would just case unnecessary pain in the client end. Affected
686 file silcd/command.c.
688 * Fixed a channel key payload sending to use correct channel
689 ID when the server was forced to change the channel's ID by
690 router. Router sent the key payload with the old Channel ID.
691 Affected file silcd/packet_receive.c.
693 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Call silc_server_save_channel_key only if the key payload
696 was provided in the JOIN command's command reply. Affected
697 file silcd/command_reply.c.
699 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Fixed silc_mp_sizeinbase to return the value correctly with
702 MPI. Affected file lib/silcmath/mp_mpi.c.
704 * Fixed the stop_server signal to correctly stop the scheduler
705 and gracefully stop the server when SIGTERM or SIGINT signals
706 are received. Affected file silcd/silcd.c.
708 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
710 * Simple handling of TERM and HUP signals. Also added some log
711 flushing call around. Affected file is
714 * Fixed small bugs in silclog.c. Now buffering output will take
715 effect after 10 seconds since startup: This will ensure that
716 no important startup messages are lost. Also output redirection
717 will preserve original format ([Date] [Type] message).
718 Affected file is lib/silcutil/silclog.c.
720 * Added two options to the config file, in the logging section:
721 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
722 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
724 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
726 * Do not print the warning about log files not being initialized
727 more than once to avoid excess logging. Affected file is
728 lib/silcutil/silclog.c.
730 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
731 the SIM copying in make install in Makefile.am.pre.
733 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
735 * Rewritten silclog APIs. Globally interesting changes follows:
736 silc_log_set_files() changed to silc_log_set_file().
737 silc_log_set_callbacks() changed to silc_log_set_callback().
738 ROBOdoc documented silclog header file.
739 SilcLogCb now returns bool to wether inihibit the default
740 handler or not (to keep the old behaviour return always TRUE).
741 The new APIs should also fix the problem of the
742 silcd_error.log file that was written in the current directory.
745 Log files streams will remain opened after silc_log_set_file()
746 call, means less CPU usage notably on high traffic servers.
747 File streams are now full buffered, and flushed to the disk
748 every 5 minutes, lesses HD activity and CPU usage.
749 Messages can be redirected, allowing admins to configure
750 one single logfile for all server messages.
751 the silc_log_quick global variable to activate fast-logging.
752 Affected files lib/silcutil/silclog.[ch]
754 * Changed some code to conform new silclog APIs. Affected
755 files are doc/example_silcd.conf.in, silcd/server.c
756 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
759 * Fixed a memory leak that could occur in some situations.
760 Affected file silcd/serverconfig.c.
762 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
764 * Added the silc_client_del_client to remove the client from
765 all channels as well. Affected file lib/silcclient/idlist.c.
767 * Fixed the client library to correctly remove the client
768 from all channels when the client entry is being destroyed.
769 Affected file lib/silcclient/client_notify.c, command.c.
771 * Added auto-nicking support to the client library. If the
772 applicatio now sets client->nickname it will be sent to the
773 server after connecting by the library. This way for example
774 SILCNICK (or IRCNICK) environment variables will have effect
775 and always change the nickname automatically to whatever
776 it is wanted. Affected file lib/silcclient/client.[ch].
778 * Renamed silc_server_command_bad_chars to the
779 silc_server_name_bad_chars and moved it to the
780 silcd/server_util.[ch]. Added also new function
781 silc_server_name_modify_bad to return nickname that
782 includes bad characters as new nickname without those
783 bad characters. This check and modify is now used in
784 silc_server_new_client when the username is initially set
785 as nickname, so it must be checked to be valid nickname.
786 Affected file silcd/packet_receive.c.
788 * The nickname length is now taken from the packet for real
789 and not trusted to strlen() since it clearly can return
790 wrong length for nickname including bad characters. This
791 also applies to channel names. Affected file silcd/command.c.
793 * Removed the lib/silcsilm/modules directory. Modules are now
794 compiled into the lib/silcsim. Fixed the copying of the
795 modules to follow symbolic links in Makefile.am.pre.
797 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
799 * Fixed silc_string_regexify list creation. Fixes bugs with
800 BAN and INVITE commands in server. The affected file is
801 lib/silcutil/unix/silcunixutil.c.
803 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Removed the command destructor entirely from the server's
806 command and command reply routines. It is not needed, and
807 its usage was buggy and caused crashes. Affected files are
808 silcd/command[_reply].[ch].
810 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Cancel protocol and NULL sock->protocol if timeout
813 occurred during protocol. Affected file silcd/server.c.
815 * Cancel protocol timeouts always before calling the final
816 callback, to assure that after final callback is called
817 no other state will be called for the protocol anymore.
818 Affected file silcd/protocol.c.
820 * Print error log if incoming connection configuration could
821 not be found. Affected file silcd/server.c.
823 * Fixed JOIN command to correctly save the founder mode
824 to the client on normal SILC server, when the channel
825 was created by the router. Affected file silcd/command.c.
827 * Fixed LIST command (hopefully) to send correct reply
828 packets. Affected file silcd/command.c.
830 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * The silc_packet_receive_process now returns FALSE if the
833 read data was invalid packet, and TRUE if it was ok.
835 The server now checks that if unauthenticated connection
836 sends data and its processing fails the server will close
837 the connection since it could be a malicious flooder.
839 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
841 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Make sure the warning about error opening a log file is
844 printed only once and not everytime it fails (produces
845 too much useless log). Affected file lib/silcutil/silclog.c.
847 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
849 * Made the silc_server_daemonise() function more readable.
850 Affected file silcd/server.c.
852 * Pid file is now optional, the user may comment it out from
853 the config file. Removed define SILC_SERVER_PID_FILE, we
854 don't need a default any longer. Affected file
855 configure.in.pre, lib/Makefile.am.pre.
857 * Make some use of the pid file. The server now dies at startup
858 if it detects a valid pid file on his path. The server would
859 die anyway in this circumstance, because of the bind() failure.
860 Affected file silcd/silcd.c.
862 * No longer compiling lib/dotconf.
864 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Fixed JOIN command parsing not to crash. Affected file
867 lib/silcclient/command.c.
869 * Fied the NICK_CHANGE notify to add the new client entry
870 even it is resolved. This removes an <[unknown]> nick
871 thingy bug in the client. Affected file is
872 lib/silcclient/client_notify.c.
874 * Do not try to allocate 0 bytes (efence does not like it)
875 in lib/silccore/silccomand.c when encoding payload.
877 * Do not take IRCNICK as nickname in Irssi SILC client since
878 it is not possible to set nickname before hand connecting
879 the server (TODO has an entry about adding auto-nicking
882 * Changed the silc_server_command_pending to check whether
883 there already exists an pending entry with the specified
884 command, command identifier and pending callback. This is
885 to fix IDENTIFY and WHOIS related crashes that may register
886 multiple pending commands with same identifier. Affected
887 file silcd/command.c.
889 * Fixed the server to reconnect to the router even if it
890 was already reconnecting and EOF was received. This to
891 fix a possibility that the server wouldn't ever try to
892 auto-reconnect to the router. Affected file silcd/server.c.
894 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Fixed the server's password authentication to use the
897 length of the locally saved password, and not the one
898 sent in the packet. Affected file silcd/protocol.c.
900 * Fixed same password authentication problem in the
901 Authentication Payload handling routines in
902 lib/silccore/silcauth.c.
904 * Yet another password authentication problem fixed with
905 channel password handling in silcd/command.c.
907 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * If first character of string in silc_parse_userfqdn is '@'
910 then do not parse it. Affected file is
911 lib/silcutil/silcutil.c.
913 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
915 * Fixed minor bug in IDENTIFY command reply sending, which
916 caused various weird problems during JOIN when it was
917 resolving names for users. Affected file silcd/command.c.
919 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Fixed the IDENTIFY command reply sending to chech better valid
922 clients. It was possible to send incomplete list of replies.
923 Affected file silcd/command.c.
925 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
927 * Added silc_client_command[s]_[un]register functions now to
928 dynamically register the commands in client library. Removed
929 the static table of commands. This allows the client library
930 to call commands without causing the application to know about
931 what commands library has called.
933 Removed the INFO command reply kludge to detect when the command
934 was called by library. Now library use its own command reply
935 function for INFO command.
937 Added function silc_client_command_call to call a command.
938 Application can use it to call command, not access the structure
941 Now all commands that are sent by the client library (not
942 explicitly sent by application) use own command reply functions.
944 Affected files around lib/silcclient/ and in
945 irssi/src/silc/core/.
947 * Fixed the WHOIS command reply sending to chech better valid
948 clients. It was possible to send incomplete list of replies.
950 Fixed the WHOIS and IDENTIFY to send the request to router
951 if normal server did not do it and did not find any results.
953 Affected file silcd/command.c.
955 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
957 * Moved the internal data from SilcClient context into its
958 own file, not accesible to application. Affected files
959 lib/silcclient/client.h and lib/silcclient/client_internal.h,
960 and other files in client library.
962 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Added doc/examples installation target in Makefile.am.pre.
967 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
969 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
970 commands the found client entry will be removed from the
971 cache, after notifying application about the error. Affected
972 file lib/silcclient/command_reply.c.
974 * Changed the /MSG to check for exact nickname user gave, and
975 not let `nick' match `nick@host' if it is only one found. Now,
976 user must type the exact nickname (like nick@host2) even if
977 there are no more than one same nicks found. This is to avoid
978 a possibility of sending nickname to wrong nickname since
979 `nick' could match `nick@host'. Affected file is
980 irssi/src/core/silc-servers.c.
982 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Do not print "you are now server operator" or similar when
985 giving /away command. Affected files are
986 irssi/src/silc/core/client_ops.c, silc-servers.h.
988 * Made the silc_server_command_pending_error_check to send
989 the same command reply payload it received back to the
990 original sender of the command. This way all arguments
991 that was received by the server will be received by the
992 client too. Affected file silcd/command.c.
994 * Added the silc_idcache_add to return the created cache entry
995 to a pointer. Affected file lib/silccore/silcidcache.[ch].
997 * Add global clients to expire if they are not on any channel.
998 This is because normal server will never know if they signoff
999 if they are not on any channel. The cache expiry will take
1000 case of these entries. This is done by normal servers only.
1001 The affected files are silcd/command_reply.c,
1002 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1004 * If server receives invalid ID notification for WHOIS or
1005 IDENTIFY and the ID exists in the lists, it is removed.
1006 Affected file silcd/command_reply.c.
1008 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1009 in client then client entry that it matches is searched and
1010 the nickname is printed on the screen for user. Affected
1011 file irssi/src/silc/core/client_ops.c.
1013 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Use cache entry expire time in the LIST command reply to
1016 purge old entries from the cache after the LIST command
1017 reply has been received. This way we don't have non-existent
1018 entries in the cache for too long. Affected file is
1019 silcd/command_reply.c.
1021 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * If we are normal server, and we've not resolved client info
1024 in WHOIS or IDENTIFY from router, and it is global client,
1025 we'll check whether it is on some channel. If it is not
1026 then we cannot be sure about its validity and will resolve it
1027 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1028 file silcd/command.c.
1030 * Search channel by name (if possible) rather than by ID
1031 in IDENTIFY command's command reply. Affected file is
1032 silcd/command_reply.c.
1034 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1037 Updated specs and implemented it. Affected file silcd/command.c,
1038 silcd/packet_send.c and silcd/packet_receive.c.
1040 * Implemented the <founder auth> payload handling in the JOIN
1041 command. If provided all conditions for channel joining
1042 except requirement to provide correct passphrase can be
1043 overrided by the channel founder. Updated the protocol specs.
1044 Affected file silcd/command.c.
1046 Added support for founder auth in JOIN command in client
1047 library. Fixed the parsing of the JOIN command now to support
1048 all options as they should be. The affected file is
1049 lib/silcclient/command.c.
1051 * Optimized the WHOIS and IDENTIFY commands to send the request
1052 to router only if it includes nicknames or other names. If
1053 they include only IDs then check the local cache first before
1054 routing. Affected file is silcd/command.c.
1056 * Added channels topic announcements. Affected file is
1057 silcd/packet_receive.c and silcd/server.c.
1059 * Fixed the silc_server_send_notify_topic_set to really destine
1060 the packet to channel. Affected file silcd/packet_send.c.
1062 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1063 library. Affected file lib/silcclient/client_notify.c.
1065 * Added UMODE announcements. Affected file silcd/server.c.
1067 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Memory leak fixes in:
1071 lib/silcutil/silcsockconn.c
1072 lib/silcske/silcske.c
1073 lib/silcske/groups.c
1075 lib/silccrypt/silcpkcs.c
1076 lib/silccore/silccommand.c
1077 lib/silccore/silcidcache.c
1082 * ROBOdoc documented the lib/silcske/groups.h file and a
1083 bit changed the interface for better.
1085 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1087 * Update the client entry context in the ID cache after
1088 nick change. Affected file lib/silcclient/command.c.
1089 Fixes the CUMODE command when regaining founder privileges,
1090 and a little WHOIS problem.
1092 * Fixed silc_net_gethostbyname to correctly call the
1093 inet_ntop. Affected file lib/silcutil/silcnet.c.
1095 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1097 * Added IPv6 support checking to the configure.in.pre, added
1098 also --enable-ipv6 option to override the check. Affected
1099 file configure.in.pre.
1101 * The silc_thread_create now calls the start function
1102 directly if threads support is not compiled in. Removes
1103 ugly #ifdef's from generic code. Affected files are
1104 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1106 * Added silc_net_gethostby[name/addr]_async to asynchronously
1107 resolve. Affected files are lib/silcutil/silcnet.[ch].

1118 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1119 routines. Added silc_net_is_ip[4/6]. Affected file is
1120 lib/silcutil/unix/silcunixnet.c. All routines that take
1121 address as argument now supports both IPv4 and IPv6 addresses.
1123 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1125 * Fixed LIST command reply sending in server. Affected file
1128 * Server now sends the kicker's client ID in the KICK notify
1129 to the kicked client. Affected file silcd/command.c.
1131 * The client library now parses the kickers client ID and
1132 UI displays it. Affected files lib/silcclient/client_notify.c
1133 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1135 * Made all payload parsing function prototypes consistent.
1136 They all take now const unsigned char * and uint32 pair as
1137 the payload data instead of SilcBuffer. Changes all around
1138 the source tree. Other unsigned char* -> const unsigned char*
1139 changes around the tree as well.
1141 * Optimized SFTP client and server packet sending not to
1142 allocate new buffer for each packet but to recycle the
1143 first allocated buffer. Affected files are
1144 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1146 * Optimized the SFTP client to use SilcList instead of
1147 SilcDList for requests, because it is faster. Affected file
1148 is lib/silcsftp/sftp_client.c.
1150 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1151 into lib/silccore/silcid.[ch].
1153 Renamed silcpayload.[ch] into silcargument.[ch].
1155 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * If client entry is deleted with active key agreement
1158 session, abort the session.
1160 The silc_client_abort_key_agreement now calls the completion
1161 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1163 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1166 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Don't use __restrict in older GCC's. Affected file is
1169 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1171 * silc_net_localhost now attempts to reverse lookup the
1172 IP/hostname. Affected file lib/silcutil/silcnet.c.
1174 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1175 command. It can be used to gain founder privileges at
1176 the same time when joining the channel.
1178 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1179 kicker's client ID as well. Updated protocol specs.
1181 Defined that the server must send SILC_COMMAND_IDENTIFY
1182 command reply with error status to client who sent
1183 private message with invalid client ID.
1185 Updated the protocol specification.
1187 * Added silc_server_send_command_reply to send any
1188 command reply. Affected file silcd/packet_send.[ch].
1190 * Added silc_id_payload_encode_data to encode ID payload
1191 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1193 * The server now send IDENTIFY command reply with error
1194 status if client ID in private message is invalid. Affected
1195 file silcd/packet_receive.c.
1197 * Save the server key file with server's IP address in
1198 the filename instead of hostname. The affected file is
1199 irssi/src/silc/core/client_ops.c.
1201 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1206 * Added libtool support for compiling shared objects in
1207 lib/silcsim. Affected file configure.in.pre and
1208 lib/silcsim/Makefile.am. Original patch by cras.
1210 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Pid file configuration, and server's config file fixes
1213 patch by toma. Updated CREDITS file.
1215 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Fixed silc_client_channel_message to not try to decrypt
1218 the message twice if it resolved the destination client
1219 information. This could cause of dropping one channel
1220 message. Affected file lib/silcclient/client_channel.c.
1222 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1225 lib/silcclient/client.c. This function is used when the SILC
1226 Client is run under some other scheduler, or event loop or
1227 main loop. On GUI applications, for example this may be
1228 desired to used to run the client under the GUI application's
1229 main loop. Typically the GUI application would register an
1230 idle task that calls this function multiple times in a second
1231 to quickly process the SILC specific data.
1233 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1235 * Fixed silc_server_drop() for dropping the supplementary
1236 groups as well, this could cause a security hole on some
1239 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1244 * Write PID file after dropping privileges. Added -F option
1245 to run server on foreground. A patch by debolaz.
1246 Affected files silcd/server.c, silcd/silcd.c.
1248 * Fixed MOTD to return the MOTD file server name. Affected
1249 file silcd/command.c.
1251 * Added INFO command reply handling to the Irssi SILC Client.
1252 Affected file irssi/src/silc/core/client_ops.c.
1254 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1256 * Fixed the silc_idcache_list_* routines to really support
1257 the dynamic list. Fixes a crash. Affected file is
1258 lib/silccore/silcidcache.c.
1260 * Fixed the LIST command reply to really call LIST command's
1261 pending callbacks. Affected file silcd/command_reply.c.
1263 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Update conn->local_entry->nickname after giving NICK
1266 command. Affected file lib/silcclient/command.c.
1268 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1270 * Added the [pid] option to the silcd configuration file
1272 Affected files: serverconfig.[ch] and silcd.c
1274 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Save fingerprint in WHOIS command reply in server.
1277 Affected file silcd/command_reply.c.
1279 * Fixed NICK commands pending callback registration.
1280 Affected file lib/silcclient/command.c.
1282 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Use ++server->cmd_ident when sending commands in server,
1285 instead of random number. Affected file silcd/command.c.
1287 * Fixed GETKEY command reply to call actually GETKEY pending
1288 command callbacks. Affected file silcd/command_reply.c.
1290 * A bit stricter check for nicknames. Check for same nickname
1291 in NICK command also. Affected file silcd/command.c.
1293 * Do not call INFO command everytime client ID changes, only
1294 during first connecting. Affected file lib/silcclient/client.c.
1296 * Set the new nickname only after successful command reply for
1297 NICK command is returned by server. Affected file
1298 lib/silcclient/command.c.
1300 * Remove nicknames from nicklist during server_signoff notify.
1301 Should fix /NAMES bit more. The affected file is
1302 irssi/src/silc/core/silc-channels.c.
1304 * Added `fingerprint' field to the SilcIDListData in the
1305 silcd/idlist.h to hold the fingerprint of the client's
1308 Send the fingerprint of the client's public key in WHOIS
1311 Affected files silcd/command.c, and silcd/idlist.[ch].
1313 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1314 create fingerprint from given data.
1316 * Show the fingerprint of the client's public key in WHOIS.
1317 Affected files irssi/src/module-formats.[ch] and
1318 irssi/src/silc/core/client_ops.c.
1320 * Format the multiple same nicknames also during JOIN and
1321 NICK_CHANGE notifys. Affected file is
1322 lib/silcclient/client_notify.c.
1324 * Do not print error on screen for invalid private message
1325 payload since it can come if someone is sending private
1326 messages with wrong key. Affected file
1327 lib/silccore/silcprivate.c.
1329 * Fixed multiple concurrent /PING crash. Affected file
1330 lib/silcclient/command.c.
1332 * Changed the wrong ID encoding. All IP addresses must be
1333 in MSB first order in encoded format. They were encoded
1334 wrong and was in LSB format. Affected files are
1335 silcd/serverid.c, lib/silcutil/silcutil.c.
1337 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1339 * Call the `connect' client operation through the scheduler
1340 in case of error. Affected file lib/silcclient/client.c.
1342 * Call the `failure' client operation even if the error
1343 occurred locally during a protocol. Affected file is
1344 lib/silcclient/protocol.c.
1346 * Added support of sending LIST command to router from normal
1347 server. This way normal server can get list of all channels
1348 in the network too. Fixed the channel list sending in the
1349 server too. Affected files are silcd/command.c, and
1350 silcd/command_reply.[ch].
1352 * Added silc_server_update_channels_by_server and
1353 silc_server_remove_channels_by_server. They are used during
1354 disconnection of primary router and in backup router protocol.
1355 Affected file silcd/server_util.[ch], silcd/server.c and
1356 silcd/server_backup.c.
1358 * Fixed channel adding to global list in IDENTIFY command
1359 reply in server. Affected file silcd/command_reply.c.
1361 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * If the incoming packet type is REKEY or REKEY_DONE process
1364 that packet always synchronously. Fixes yet another MAC
1365 failed error on slow (dialup) connections. Affected file
1366 lib/silcclient/client.c and silcd/server.c.
1368 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Call check_version SKE callback for initiator too. Affected
1371 file lib/silcske/silcske.c.
1373 * Implemented fix for security hole found in the SKE that was
1374 fixed in the specification few days back; the initiator's
1375 public key is now added to the HASH value computation.
1376 Added backwards support for the old way of doing it too, for
1377 old clients and old servers. Affected file is
1378 lib/silcske/silcske.c.
1380 * Enabled mutual authentication by default in SKE. If initiator
1381 is not providing mutual authentication the responder will
1382 force it. This will provide the proof of posession of the
1383 private key for responder. The affected files are
1384 lib/silcclient/protocol.c and silcd/protocol.c.
1386 * Do not cache anymore the server's public key during SKE.
1387 We do mutual authentication so the proof of posession of
1388 private key is done, and if the server is authenticated in
1389 conn auth protocol with public key we must have the public
1390 key already. Affected file silcd/protocol.c.
1392 * Added new global debug variable: silc_debug_hexdump. If
1393 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1394 file lib/silcutil/silclog.[ch].
1396 * Fixed compilation warning due to char * -> const char *.
1397 Affected files lib/silcutil/silcnet.h, and
1398 lib/silccore/silcauth.[ch].
1400 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Fixed CMODE command when new channel key was created. If
1403 the creation failed the old key was removed. Next time giving
1404 same command would crash the server since the old key was
1405 freed already. Affected file silcd/command.c.
1407 * Fixed the silc_server_announce_get_channels to not crash
1408 on reconnect. Affected file silcd/server.c.
1410 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Added silc_log_set_debug_string function to set a regex
1413 string to match for debug output. Only the function names,
1414 or filenames matching the given debug string is actually
1415 printed. This way it is possible to filter out those debug
1416 strings that user is not interested in.
1418 Fixed a bug in silc_string_regexify.
1420 Affected files lib/silcutil/silclog.[ch], and
1421 lib/silcutil/unix/silcunixutil.c.
1423 * Changed the -d options in both server and Irssi SILC client
1424 to take the debug string as argument. Affected files
1425 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1427 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Added silc_hash_babbleprint to create a Bubble Babble
1430 Encoded fingerprint. The encoding is developed by Antti
1431 Huima (draft-huima-babble-01.txt), and it creates human
1432 readable strings out of binary data. Affected file
1433 lib/silccrypt/silchash.[ch].
1435 * Print the babble print now in addition of fingerprint as well
1436 in Irssi SILC client. Affected files are
1437 irssi/src/fe-common/silc/module-formats.[ch],
1438 irssi/src/fe-common/silc/core/client_ops.c.
1440 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Fixed a security problem found in SKE. The initiator's
1443 public key too is now added to the HASH hash value creation
1444 which is signed by the responder to create the SIGN value.
1445 This will prevent anyone in the middle to lie to the responder
1446 about the initiator's public key. If this is done now, the
1447 man in the middle will get caught. Updated the protocol
1450 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Better installation directory handling. Configure module
1453 paths and other paths automatically to example_silc* files
1454 in doc/. A patch by toma.
1456 * Fixed compiler warning from MPI library, and from SILC RNG.
1459 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1460 It can be configured with ./configure. A patch by toma.
1462 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Find correct make to use in prepare-clean. A patch by
1465 toma. Affected file prepare-clean.
1467 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1469 * Added irssi variables use_auto_addr, auto_bind_ip,
1470 auto_bind_port and auto_public_ip.
1472 * Changed the interface for silc_client_send_key_agreement
1473 in lib/silcclient/silcapi.h
1477 irssi/src/silc/core/silc-core.c
1479 lib/silcclient/silcapi.h
1480 irssi/src/silc/core/silc-channels.c
1481 lib/silcclient/client_keyagr.c
1484 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * Added silc_pkcs_public_key_compare to compare two
1487 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1489 * Check that the client who set the founder mode on the
1490 channel is the same client that is giving the founder
1491 mode to itself. It is done by comparing the saved public
1492 key (it is saved even in the authentication is passphrase).
1493 Affected file silcd/command.c.
1495 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Do not process packet for disconnected socket connection.
1498 Affected file lib/silccore/silcpacket.c.
1500 * Process the DISCONNECT packet through scheduler in the
1501 client library. Affected file lib/silcclient/client.c.
1503 * Fixed the silc_client_packet_parse to not to increase
1504 the packet sequence number if the conn->sock and the
1505 current socket connection is not same. This can happen
1506 for example during key agreement when the conn includes
1507 multiple socket connections (listeners). Affected file
1508 lib/silcclient/client.c.
1510 * The sender of the file transfer request now provides also
1511 the pointer (listener) for the key exchange protocol. If
1512 the listener cannot be created then it sends empty key
1513 agreement and lets the receiver provide the listener.
1515 Added `local_ip' and `local_port' arguments to the
1516 silc_client_file_send. If they are provided they are used,
1517 if not then it will attempt to find local IP address, if
1518 not found or bind fails then the remote client will provide
1521 Affected files are lib/silcclient/client_ftp.c and
1522 lib/silcclient/silcapi.h.
1524 * Extended the FILE SEND command to support defining the
1525 local IP and port for key exchange listener. They are
1526 optional. Affected file irssi/src/silc/core/silc-servers.c.
1528 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Defined to WHOIS command reply the sending of fingerprint
1531 of the client's public key (if the proof of posession of the
1532 corresponding private key is verified by the server).
1533 Updated to the protocol specification.
1535 * Added support of receiving the client's public key's
1536 fingerprint in command reply in client library. Affected
1537 file is lib/silcclient/command_reply.c, and
1538 lib/silcclient/idlist.[ch].
1540 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Do not send over 128 chars long nickname to the server
1543 in NICK command. Affected file lib/silcclient/command.c.
1545 * Do not send over 256 chars long channel names to the server
1546 in JOIN command. Affected file lib/silcclient/command.c.
1548 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Assure that silc_server_close_connection cannot be called
1551 twice for same socket context. Affected file is
1554 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Send error message to application if opening file for
1557 writing during file transfer fails. Affected file is
1558 lib/silcclient/client_ftp.c.
1560 Remove all file transfer sessions for a client that we're
1561 removing from ID cache.
1563 Affected file is lib/silcclient/client_ftp.c.
1565 * Fixed silc_net_addr2bin to return correct address. Affected
1566 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1568 * Fixed file transfer session removing on signoff notify.
1569 Affected file irssi/src/silc/core/silc-servers.c.
1571 * Added the SilcClientFileError to be returned in the monitor
1572 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1573 Affected file lib/silcclient/silcapi.h.
1575 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Fixed a crash in silc_client_ftp_free_sessions and
1578 silc_client_ftp_session_free_client. Affected file
1579 lib/silcclient/client_ftp.c.
1581 * Added `disabled' field in the SilcChannelEntry in the server
1582 to indicate if the server entry is disabled. Affected file
1583 silcd/idlist.h, silcd/command[_reply].c.
1585 * SILC server adds now /var/run/silcd.pid everytime it is
1586 started. Affected file silcd/silcd.c.
1588 * Added silc_server_packet_send_clients to send a packet to
1589 the provided table of client entries. Affected file
1590 silcd/packet_send.[ch].
1592 * Fixed a crash in client resolving in client_prvmsg.c in
1593 client library. Affected file lib/silcclient/client_prvmsg.c.
1595 * Do not actually remove the client directly from ID cache
1596 during SERVER_SIGNOFF, but invalidate it. This way we
1597 preserve the WHOWAS info for the client. Affected file
1598 silcd/server_util.c.
1600 * Fixed SERVER_SIGNOFF notify handling in the server. The
1601 server is now able to process incoming SERVER_SIGNOFF notify
1602 for a server that it doesn't even know about. It will remove
1603 the clients provided in the notify. Affected file
1604 silcd/packet_receive.c.
1606 * Check for partial packet in data queue after every packet that
1607 was found from the queue. Return and wait for more data if
1608 there is partial data in queue. Affected file is
1609 lib/silccore/silcpacket.c.
1611 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Added SilcClietFileError enum to indicate error in
1614 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1615 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1616 Affected files lib/silcclient/silcapi.h and
1617 lib/silcclient/client_ftp.c.
1619 * Check that newsize in silc_buffer_realloc is larger than
1620 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1622 * Added better monitor of file transfers. It now monitors
1623 key agreement protocol during the file transfer too. Added
1624 error reporting too. Affected files
1625 irssi/src/silc/core/silc-servers.c,
1626 irssi/src/fe-common/silc/module-formats.[ch].
1628 * Wrote a help file for FILE command.
1630 * Added silc_rng_global_get_byte_fast to get not-so-secure
1631 random data as fast as possible. Random data is read from
1632 /dev/urandom if available and from the SILC RNG if not
1633 available. It is used in padding generation. Affected file
1634 lib/silccrypt/silcrng.[ch].
1636 * All packets in client library are now processed synchronously.
1637 Optimized packet processing a lot. Affected file
1638 lib/silcclient/client.c.
1640 * All server connection packets are processing synchronously
1641 now in server, to optimize packet processing. Affected file

1645 if make install is given. Affected files: all Makefile.am's.
1647 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Assure that silc_client_notify_by_server_resolve does not
1650 resolve the client information multiple times. If it cannot
1651 be found by the first it cannot be found at all. Affected
1652 file lib/silcclient/client_notify.c.
1654 * Fixed WHOWAS command reply calling. Affected file
1655 lib/silcclient/command_reply.c.
1657 * Removed all references to silc_idlist_get_client from the
1658 Irssi SILC client since that call is internal call used by
1659 the library. The Irssi SILC client will use now client
1660 retrieval functions found in silcapi.h.
1662 * Fixed a bug in resolving nickname info before sending
1663 private message. It used freed memory. Affected file
1664 irssi/src/silc/core/silc-servers.c.

1685 * Added silc_net_localip to return local host's IP address.
1686 Affected file lib/silcutil/silcnet.[ch].
1688 * If key exchange or rekey protocol is active for a connection
1689 parse all packets syncronously since there might be packets
1690 in packet queue that we are not able to process without first
1691 processing packets before them. Affected file silcd/server,
1692 lib/silcclient/client.c.
1694 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1695 whether library should continue processing the packet.
1696 Affected file lib/silccore/silcpacket.h.

1742 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1743 is incomplete and is being resolved, it won't be resolved
1746 Make sure also that USERS command reply does not resolve
1747 twice information. Affected file is
1748 lib/silcclient/command_reply.c.
1750 Make sure that silc_client_get_clients_by_list does not
1751 resolve twice same information.
1753 * Check for valid client->id in the silc_server_free_client_data.
1754 Affected file silcd/server.c.
1756 * Fixed /GETKEY nick@server not to crash if the server entry
1757 is not found. Affected file lib/silcclient/command.c.

1765 Affected file silcd/command.c.
1767 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Call the silc_server_udpate_servers_by_server in the
1770 primary router that comes back online in the backup resuming
1771 protocol. Otherwise it routes packets wrong. Affected file
1772 silcd/server_util.[ch], silcd/server_backup.c.
1774 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1777 lib/silcutil/silcbuffmt.[ch].
1779 * Redefined the SILC packet header to include the padding
1780 length. Affected file lib/silccore/silcpacket.[ch].
1782 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1783 length for maximum padding up to 128 bytes). Affected
1784 file lib/silccore/silcpacket.h.
1786 * Removed all backwards support for old 0.5.x MAC thingies.
1787 The SILC packet header change makes it impossible to be
1788 backwards compatible.
1790 * Send the ENDING packet with timeout in the backup resuming
1791 protocol. This is to assure that all routers has connected
1792 to the primary router. Affected file silcd/server_backup.c.
1794 * Changed the RNG to take the first IV from random data. It
1795 used to take it from zero actually. Changed the RNG also
1796 to use /dev/urandom during session. /dev/random is used
1797 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1799 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Changed the SILC packet header to have the first two bytes
1802 (the packet length) encrypted. Affected files aroung the
1803 code tree, lib/silccore/silcpacket.[ch]. Removed the
1804 SilcPacketCheckDecrypt callback. It is not needed anymore
1805 since the silc_packet_receive_process will determine now
1806 whether the packet is normal or special.
1808 * Implemented the unidirectional MAC keys. Affected files
1809 lib/silcske/silcske.c, silcd/protocol.c and
1810 lib/silcclient/protocol.c.
1812 * Implemented the packet sequence number to the MAC computation.
1813 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1814 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1815 lib/silcclient/protocol.c.
1817 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Allow backup router to announce servers. All servers
1820 announced by backup router are added to the global list
1821 automatically. Update hte server's socket to our primary
1822 router also when backup router announces a server.
1823 Affected file silcd/packet_receive.c.
1825 * Do not update the client->router in the function
1826 silc_server_udpate_clients_by_server if the client is on
1827 global list. We might fail to find any specific server
1828 for locally connected clients and local cell clients. They
1829 should still use the `from' and not `to' as client->router.
1830 This fixes backup router resuming protocol. Affected file
1831 silcd/server_util.c.
1833 * Decrease channel statistics count only if the channel
1834 deletion worked. Affected files are silcd/server.c and
1835 silcd/server_util.c.
1837 * Added silc_server_update_servers_by_server to update origin
1838 of all server entries. Used during backup router protocol.
1839 Affected files silcd/server_util.[ch], silcd/server.c. and
1840 silcd/backup_router.c.
1842 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1843 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1844 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1845 lib/silccrypt/silchmac.c.
1847 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Assure that router cannot reroute the same channel message
1850 to the sender. Affected file silcd/packet_receive.c.
1852 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Made better checks that the channel message is not sent
1855 to the router it came from. Affected file is
1856 silcd/packet_send.c. Fixed memory leak too.
1858 * Announce informations for incoming router connection, but
1859 only after checking if it is replaced by backup router.
1860 Affected file silcd/packet_receive.c.
1862 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Fixed the backup resuming protocol to work in multiple
1865 router environment. Affected file silcd/server_backup.c.
1867 * Route packet only to one router in the function
1868 silc_server_packet_send_to_channel. Affected file is
1869 silcd/packet_send.c.
1871 * Fixed silc_server_send_notify_dest to set the broadcast
1872 flag. Fixed the silc_server_send_notify_topic to actually
1873 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1874 Affected file silcd/packet_send.c.
1876 * Changed the SFTP Filesystem interface. Changed the
1877 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1878 the filesystem operation function. The SilcSFTPFilesystem
1879 is now a context that is allocated by all filesystem allocation
1880 functions and it already includes the operations structure
1881 and filesystem specific context. It is given as argument
1882 now to the silc_sftp_server_start. This made the interface
1883 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1884 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1886 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Changed the backup router adding and getting interfaces
1889 in the server. The router that will be replaced by the
1890 specified backup router is now sent as argument. Affected
1891 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1894 * Added silc_net_addr2bin_ne to return the binary form of
1895 the IP address in network byte order. Affected files
1896 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1898 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Check for existing server ID in silc_server_new_server
1901 and in silc_server_connect_to_router_final and remove the
1902 old entry if it exists. Affected file silcd/packet_receive.c,
1905 * Send the channel message always to only one router, either
1906 in upstream or downstream. Affected file is
1907 silcd/packet_send.c.
1909 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Wrote the definition of the backup resuming protocol to the
1912 protocol specification.
1914 * Removed one redundant channel key generation from normal
1915 server during joining procedure. Removed one redundant
1916 channel key sending from server to router during joining
1917 procedure. Affected file silcd/command.c.
1919 * Made minor bugfixes to the backup router resuming protocol.
1920 Affected file silcd/server_backup.c, server.c.

1925 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1928 * Implemented the backup resuming protocol that is used to
1929 resume the primary router position in the cell after the
1930 primary router comes back online. Affected files
1931 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1932 and silcd/server_util.[ch].
1934 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Sleep two (2) seconds after sending QUIT command to server.
1937 Affected file lib/silcclient/command.c.
1939 * Assure that if outgoing data buffer is pending do not force
1940 send any data. Affected file silcd/packet_send.c.
1942 * Assure that if outgoing data buffer is pending do not force
1943 send any data. Affected file lib/silcclient/client.c.
1945 * Implemented the backup router support when the primary router
1946 goes down. The servers and routers can now use the backup
1947 router as new primary router without loosing connectivity.
1949 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1952 in the server to indicate disabled entry. All data read
1953 from the connection will be ignored and no data is sent
1954 for entry that is disabled. Affected files are
1955 silcd/idlist.h, silcd/server.c.
1957 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Created SFTP client and server test programs in the
1960 lib/silcsftp/tests directory.
1962 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Implemented memory filesystem (virtual filesystem) for
1965 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1968 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Implemented the SFTP (SSH File Transfer Protocol) to the
1971 lib/silcsftp. It includes SFTP client and SFTP server
1974 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Moved lib/silccore/silcprotocol.[ch] to the
1977 lib/silcutil library.
1979 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1980 take variable argument list pointer as argument. Affected
1981 file lib/silcutil/silcbuffmt.[ch].
1983 * Added silc_buffer_set function that is used to set data
1984 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1985 Affected file lib/silcutil/silcbuffer.h.
1987 * Changed various routines in the core library to use the new
1988 silc_buffer_set instead of allocating new buffer only for
1991 * Added 64-bit value formatting and unformatting support to the
1992 silc_buffer_[un]format routines. Affected file is
1993 lib/silcutil/silcbuffmt.[ch].
1995 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1996 to includes/bitmove.h.
1998 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Fixed channel user mode saving in client library. Affected
2001 file lib/silcclient/command[_reply].c.
2003 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Defined the file transfer to the SILC Protocol. Added
2006 new packet type SILC_PACKET_FTP and defined File Transfer
2007 Payload. The mandatory file transfer protocol is SFTP
2008 (SSH File Transfer Protocol). Affected file in addition
2009 of the internet draft is lib/silccore/silcpacket.h.
2011 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2012 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2013 is used as part of backup router protocol when the primary
2014 router of the cell is back online and wishes to resume
2015 the position as primary router.
2017 * Redefined the MAC generation keys in the protocol. The
2018 same key is not used anymore in both direction. Both
2019 direction will now use different keys for sending and
2020 receiving. This fixes a potential security flaw. This
2021 change causes incompatibilities in the protocol.
2023 * Redefined also the MAC computation from the packet.
2024 An packet sequence number is now added to the MAC
2025 computation. This prevents possible replay attacks against
2026 the protocol. This change too causes incompatibilities
2029 Added `sequence' field to the SilcPacketContext to hold
2030 the current sequence number for the packet.
2032 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Added `created' field to the SilcIDListData in the file
2035 silcd/idlist.h to indicate the time when the entry was
2038 * Added `created' field to the SilcChannelEntry too. Affected
2039 file silcd/idlist.h.
2041 * Added `creation_time' aguments to all the announcement functions
2042 in the server. If it is provided then only the entries that
2043 was created after the provided time frame are actually
2044 announced. Affected file silcd/server.[ch].
2046 * The protocol says that the Channel ID's IP address must be
2047 based on the router's IP address. Added check for this in
2048 the silc_server_new_channel when processing incoming New Channel
2049 Payload. Affected file silcd/packet_receive.c.
2051 * Print out the correct version with --version in SILC client.
2052 Affected file irssi/src/silc/core/silc-core.c.
2054 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Fixed WHOWAS command to check for completnes of the client
2057 entry always, not just when the command is coming from client.
2058 Affected file silcd/command.c.
2060 * Added new function silc_server_packet_queue_purge to purge the
2061 outgoing data queue to the network. After the function returns
2062 it is guaranteed that the outgoing packet queue is empty.
2063 Affected file silcd/packet_send.[ch].
2065 * Purge the outgoing packet queue in the rekey protocol's final
2066 callback to assure that all rekey packets go to the network
2067 before quitting the protocol. Affected file silcd/server.c.
2069 * Added silc_client_packet_queue_parse as similar function as
2070 in server to the client library. The affected file is
2071 lib/silcclient/client.c.
2073 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Splitted silcd/server.c and created silcd/server_util.[ch]
2076 for utility functions.
2078 * Added new socket flag SILC_SF_DISABLED to indicate that the
2079 connection is open but nothing can be sent to or received from
2080 the connection. Affected file lib/silcutil/silsockconn.[ch].
2081 The checking for disabled socket is checked in the low level
2082 silc_socket_write and silc_socket_read functions.
2084 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Allow only nicknames and channel names that fits into the
2087 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2089 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * When processing JOIN command reply in server check that if
2092 the channel exists in our global list we'll move it the local
2093 list. Affected file silcd/command_reply.c.
2095 * Fixed the check whether client is joined on the channel already
2096 in JOIN command. Affected file lib/silcclient/command.c.
2098 * Fixed the JOIN command reply to check whether the channel
2099 already exists. Affected file lib/silcclient/command_reply.c.
2101 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Added silc_ske_status_string to map the SKE error numbers
2104 to readable strings. The affected files are
2105 lib/silcske/silcske[_status].[ch].
2107 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Do not show the private channels on the WHOIS channel list
2110 as it is not allowed by the protocol. The affected file is
2113 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Assure that the packet length digged from the actual packet
2116 is something sensible in the silc_packet_decrypt_rest_special
2117 in lib/silccrypt/silcpacket.c.
2119 * Free and NULL the allocated pointer in silc_hmac_alloc if
2120 the HMAC allocation fails. The affected file is
2121 lib/silccrypt/silchmac.c.
2123 * Print the selected security properties to the log files in
2124 the server. Affected file silcd/protocol.c.
2126 * Add SKE's reference counter even if calling the completion
2127 callback manually. Otherwise it goes negative, although it
2128 does not cause any problems. The affected file is
2129 lib/silcske/silcske.c.
2131 * Remove the client entry with short timeout after giving the
2132 KILL command. Affected file lib/silcclient/command.c.
2134 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2135 case all found clients are already disconnected (WHOWAS would
2136 found them) in the server. Affected file silcd/command.c.
2138 * Update the last_receive (time of last data received) to be
2139 updated only when received private or channel message so that
2140 the idle time showed in WHOIS makes more sense.
2142 * Added boolean field `valid' in to the SilcClientEntry in the
2143 client library to indicate whether the entry is valid or not.
2144 This fixes the nickname change bug on channel when changing
2145 the nickname to be same than the old (like nick to Nick) the
2146 nickname formatter doesn't set the new nick anymore to Nick@host.
2147 Affected file lib/silcclient/idlist.[ch].
2149 * Now actually fixed the nickname changing on disconnection.
2150 Added new function silc_change_nick to the Irssi SILC Client.
2151 Affected file irssi/src/silc/core/client_ops.c,
2152 irssi/src/silc/core/silc-nicklist.[ch].
2154 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Check that the public key exists in the GETKEY command before
2157 trying to encode it. Affected file silcd/command.c.
2159 * Print some notifications on received public keys with GETKEY
2160 command in the Irssi SILC Client. Affected files are
2161 irssi/src/fe-common/silc/module-formats.[ch],
2162 irssi/src/silc/core/client_ops.c.
2164 * Use IDENTIFY command to resolve the server information in the
2165 GETKEY command instead of INFO command. Affected file
2166 lib/silcclient/command.c.
2168 * All command reply functions in the client library now calls
2169 the pending command reply callbacks even if an error has
2170 occurred. The server has done this a long time and now it was
2171 time to move the client library to this as well. Now all
2172 errors can be delivered back to the pending command reply
2173 callbacks if necessary. Affected files are
2174 lib/silcclient/command[_reply].[ch].
2176 * Change the nickname on disconnection back to the username
2177 because in reconnect the server will enforce it to it anyway.
2178 Affected file irssi/src/silc/core/silc-servers.c.
2180 * Fixed a config file parsing bug in the Irssi SILC client.
2181 Affected file irssi/src/silc/core/clientconfig.c.
2183 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * When printing the channel mode on JOIN, verify that the
2186 channel key and channel's HMAC are valid. Affected file
2187 irssi/src/silc/core/client_ops.c.
2189 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2192 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2193 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2195 * Removed channel key rekey task deleting from the function
2196 silc_server_save_channel_key. Affected file silcd/server.c.
2197 Added explicit timeout task context instead that is used to
2198 delete the task if we are registering a new task before the
2199 new task has elapsed.
2201 * When channel key rekey occurs the client library now saves
2202 the old channel key for a short period of time (10 seconds) and
2203 is able to use it in case some is still sending channel
2204 messages encrypted with the old key after the rekey. Affected
2205 file lib/silcclient/[idlist.h|client_channel.c].
2207 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Added check to the silc_server_new_id_real to not accept
2210 new ID if it is the sender's own ID. Affected file is
2211 silcd/packet_receive.c.
2213 * Assure that we do not announce ourself or the one we've
2214 sending our announcements when we're router and are announcing
2215 servers to our primary router. Affected file silcd/server.c.
2217 * Fixed silc_server_command_identify_check_client to assemble
2218 correct WHOIS packet. It send corrupted WHOIS packet and
2219 caused problem with router to router connections. Affected
2220 file silcd/command.c.
2222 Fixed also silc_server_command_whois_check the same way
2223 as for the IDENTIFY command.
2225 * Added new SilcIDListStatus to the server in the SilcIDListData
2226 structure. The status now includes the current status of
2227 the entry (like registered, resolved etc.). Affected file
2228 silcd/idlist.[ch]. Defined a bunch of different status types
2229 as well. This replaced the old boolean registered field as well.
2231 Added resolve_cmd_ident field to the SilcClientEntry structure
2232 too so that if the entry is for example being resolved so
2233 another command may attach to the same pending command reply
2234 without requiring to resolve the same entry again. This concept
2235 should optimize the WHOIS and the IDENTIFY resolving under
2236 heavy load by taking away unnecessary resolving for entries
2237 that are being resolved already.
2239 Added support for adding multiple pending commands for one
2240 command idenfier. Affected file silcd/command[_reply].[ch].
2242 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2243 before deleting the data. Otherwise the hash table will have
2244 freed data in comparison functions. Affected file is
2245 silcd/command_reply.c.
2247 * Fixed silc_idlist_replace_client_id to add the new entry to
2248 the cache with NULL nickname. Otherwise there will be invalid
2249 memory as the nickname after the nickname is freed. Affected
2250 file silcd/packet_receive.c.
2252 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2253 saved into wrong slots because the previous number of entries
2254 was not taken into account. Affected file silcd/idlist.c.
2255 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2257 * If we are router and we receive JOIN notify to a channel that
2258 does not have any users then notified client is marked as the
2259 channel founder, as it is it. The affected file is
2260 silcd/packet_receive.c
2262 * Added to the extended hash table API's table_del_*ext functions
2263 the destructor as argument too, so that the caller can decide
2264 which destructor to use or whether to use destructor at all.
2265 Affected file lib/silcutil/silchashtable.[ch].
2267 * Fixed ID Cache purging. It actually deleted the entries from
2268 the hash table after the data was freed. The hash table ended
2269 up comparing freed memory. The affected file is
2270 lib/silccore/silcidcache.c.
2272 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Fixed Irssi SILC client's KILL command's HELP syntax.
2276 * The USERS command now resolves the detailed user information
2277 if the userinfo field is missing. Affected file is
2278 lib/silcclient/command_reply.c.
2280 * Do not print error in silc_file_read if the read file does
2281 not exist. Just silently return NULL. Affected file is
2282 lib/silcutil/silcutil.c.
2284 * Fixed the silc_log_output to not wine about NULL filename
2285 and to not create some bogus " " filename. Affected file is
2286 lib/silcutil/silclog.c.
2288 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Fixed various printing bugs on the user interface in the
2291 Irssi SILC Client. Minor changes that were forgotten from
2294 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed the configure.in.pre and the compilation and distribution
2297 environment to support the new autoconf 2.52. That version is
2298 now required to compile the CVS trunk.
2300 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2303 to generally parse user@fqdn format strings. Affected file
2304 lib/silcutil/silcutil.c.
2306 * Added nickname_format and nickname_force_format fields to the
2307 SilcClientParams structure. The first one defines the format
2308 for the nicknames that the library will enforce if the receives
2309 multiple same nicknames. The second one is boolean value and
2310 can be used to force the library to always enforce the format
2311 to the nicknames regardles whether there are multiple nicknames
2312 or not. This configurable formatting was employed to flexibly
2313 support accessing multiple nicknames from the user interface.
2314 The userinterface can now set the nicknames to what ever format
2315 they prefer. Affected file lib/silcclient/silcapi.h.
2317 Added function silc_client_nickname_format to the file
2318 lib/silcclient/idlist.c. It performs the nickname formatting.
2320 Added new field `hostname´ to the SilcClientEntry context.
2321 It holds the hostname of the client. Affected file is
2322 lib/silcclient/idlist.h.
2324 * Irssi SILC Client sets the nicknames in nick@hostn format.
2325 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2326 irssi/src/silc/core/silc-core.c.
2328 The WHOIS printing now also shows both the real nickname and
2329 the formatted nickname so that user knows how to access the
2330 user if there are multiple same nicknames cached. Affected
2331 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2332 printing formatting too to take the hostname now as a separate
2333 argument. The Affected file is
2334 irssi/src/fe-common/silc/modules-formats.[ch].
2336 * Changed the silc_client_get_clients_local to accept the formatted
2337 nickname as argument. It accepts the real nickname too but the
2338 formatted nickname can be used to find the true entry from
2339 multiple entries. Affected file lib/silcclient/silcapi.h and
2340 lib/silcclient/idlist.c.
2342 * Added nickname_format_parse field to the SilcClientParams.
2343 It is a callback function provided by the application to parse
2344 the nickname out of the formatted nickname string. The library
2345 calls it to get the nickname from the formatted string. Since
2346 the application generally knows better the format of the nickname
2347 string it parses it instead of the library, even though library
2348 encodes the formatted string. If the callback function is not
2349 provided then the library will use the string as is. The
2350 affected file is lib/silcclient/silcapi.h.
2352 * All the nickname strings passed to the client library in
2353 commands are now expected to be formatted nickname strings.
2354 If the command does not support the formatted nickname string
2355 it will assume that the sent string is the actual nickname.
2356 Affected file lib/silcclient/command.c.
2358 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Added public key authentication support to OPER and SILCOPER
2361 commands in the client library. Affected file is
2362 lib/silcclient/command.c.
2364 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Changed the get_auth_methdod client operation to be asynchronous.
2367 It can be async if the application resolves the authentication
2368 method from the server during the negotiation. Added new
2369 SilcGetAuthMeth completion callback that the application will
2370 call after resolving the authentication method.
2372 Added function silc_client_request_authentication_method that
2373 the application can use to resolve the authentication method
2374 from the server. Added also SilcConnectionAuthRequest callback
2375 that the library will call after the server has replied. The
2376 application can call this function if it does not know the
2377 current authentication method.
2379 Affected files are lib/silcclient/client.c and
2380 lib/silcclient/silcapi.h.
2382 * The Irssi SILC client now automatically resolves the authentication
2383 method incase any configuration information is not present (and
2384 currently there never is). The affected file is
2385 irssi/src/silc/core/client_ops.c.
2387 * Fixed public key authentication from the client library.
2388 Affected file lib/silcclient/protocol.c. Changed also the
2389 protocol specification about the public key authentication in
2390 the connection authentication protocol. The actual data to be
2391 signed is now computed with a hash function before signing.
2393 * Fixed the public key authentication from the server as well.
2394 Affected file silcd/protocol.c.
2396 * Removed the mlock()'s from the memory allocation routines.
2397 Affected file lib/silcutil/silcmemory.c. The ./configure does
2398 not check anymore for the mlock(). Affected file is
2401 * Fixed USERS command in server to allow the execution of the
2402 command for private and secret channels if the client sending
2403 the command is on the channel. Affected file silcd/command.c.
2405 * Fixed silc_client_get_clients_local to return the clients
2406 count correctly. It could return wrong value. Affected file
2407 lib/silcclient/idlist.c.
2409 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2412 types. The assembler optimizations seemed not to like 64-bit
2413 data types. The assmebler optimizations thus are now enabled
2414 also for BSD systems as opposed to only enable them for Linux.
2416 * Do not check for threads at all on BSD systems. Affected
2417 file configure.in.pre.
2419 * Removed -n and -h options from the Irssi SILC Client since
2420 they are not used in silc.
2422 * Fixed the prime generation to assure that the first digit
2423 of the generated random number is not zero since our conversion
2424 routines does not like number strings that starts with zero
2425 digit. If zero digit is seen the random number is regenerated.
2426 This caused some corrupted RSA keys when the zero first digit
2427 was met. Affected file lib/silcmath/silcprimegen.c.
2429 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Fixed WIN32 configuration in the ./configure script.
2432 Fixed to include xti.h on environments that has it.
2433 Patches by Carsten Ilchmann and andrew.
2435 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Changed the silc_id_create_client_id to be collision
2438 resistant. It is now assured that there cannot be created
2439 two same client ID's. I suspect that some weird bugs in
2440 the server were actually caused by duplicate Client IDs.
2441 Affected file silcd/serverid.[ch]. A router receiving
2442 new ID now also assures and informs the sending server
2443 if the ID caused collision.
2445 * Changed the silc_id_create_channel_id to also assure that
2446 there are no collisions.
2448 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Statement about ignoring the Mutual Authentication flag when
2451 performing rekey with PFS was a bit misleading. It is ignored
2452 if it was set in the initial negotiation, it cannot be even
2453 set in the rekey. Fixed in the ke-auth draft. Started the
2454 new versions of the protocol drafts in the doc/.
2456 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Fixed a bug in silc_client_command_identify_save when saving
2459 new channel information. The channel name was no duplicated
2460 and caused crash on exit. Affected file is
2461 lib/silcclient/command_reply.c.
2463 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Fixed the getkey command handling in the server. Send just
2466 empty OK reply to the sender if the key could not be fetched
2467 (but everything else was ok, like the key just was not available).
2468 Changed the public key parameter to optional in the protocol
2469 specs so that empty OK reply can be sent. Affected file
2472 Added a message to Irssi SILC client to tell to user if the
2473 server did not return a public key.
2475 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Fixed a channel key regeneration bug. It registered new
2478 timeout tasks exponentially until all system resources were
2479 used. Affected file silcd/server.c.
2481 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Added the SILC Document generator to the scripts/silcdoc.
2484 It can be used to generate the Toolkit Reference Manual out
2485 of the source tree. Internally it will also use the RoboDoc
2486 generator now imported in util/robodoc.
2488 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Added couple of return's in rekey protocol if error orccurred
2491 during the protocol. The execution must be terminated.
2492 Affected file silcd/protocol.c. Also, terminate the protocol
2493 always with timeout.
2495 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * The client's Client ID was created initally from the wrong
2498 nickname (it could have been in format nick@host) in the
2499 silc_server_new_client. Affected file silcd/packet_receive.c
2501 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Added some SILC_LOG_ERROR's to various error conditions
2504 if client could not be added to ID cache. Affected files
2505 silcd/packet_receive.c and silcd/server.c.
2507 * When client's sock->user_data is freed, NULL also the
2508 client->router and client->connection pointers. Added check
2509 for these pointers being NULL to various places around the
2510 code. Affected file silcd/server.c.
2512 * Added client->data.registered == TRUE checks to various
2513 places around the code to assure that unregistered client's
2514 are not handled when it is not allowed. Affected file
2517 * Added `bool registered' fields to all
2518 silc_idlist_[server|client]_get_* routines to indicate whether
2519 the fetched client needs to be registered or not. Affected
2520 file silcd/idlist.[ch].
2522 * Add your own entry as registered to the ID cache in the
2523 server. Affected file server.c.
2525 * Fixed a bug in silc_server_new_server. The SilcServer was
2526 set as the new server's context instead of SilcServerEntry.
2527 This naturally caused some weird bugs.
2529 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Do not delete the channel rekey task when adding it
2532 for in silc_server_create_channel_key.
2534 * Changed the silc_server_create_channel_key to return
2535 TRUE or FALSE to indicate the success of the channel key
2538 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Fixed MSVC++ project files and added missing files to
2541 Makefiles under win32/.
2543 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Do not add TCP_NODELAY flag if the operating system
2546 does not have it defined. Affected files are
2547 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2549 * Fixed buffer overflow from Irssi SILC Client. Affected
2550 file irssi/src/fe-common/core/themes.c.
2552 * Fixed double free in client library in the file
2553 lib/silcclient/client.c when disconnecting from server.
2555 * Applied double free patch from cras to Irssi SILC client.
2556 Affected files irssi/src/core/[modules/expandos].c
2558 * Fixed the disconnection handling to Irssi SILC Client.
2559 The application must call silc_client_close_connection
2560 in ops->connect client operation in case of failure of
2561 the connection. Affected file is
2562 irssi/src/silc/core/client_ops.c.
2564 * Do not set sock->protocol to NULL in the function
2565 silc_client_close_connection after executing the protocol's
2566 final callback since the sock might not be valid anymore.
2567 Affected file lib/silcclient/client.c.
2569 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Do not enable SILC_THREADS if the linking with libpthread
2572 did not happen. Affected file configure.in.pre.
2574 * Added notion to protocol specification that server must
2575 verify the sent authentication payload with CMODE when
2576 setting the channel founder key. Implemented it to the
2577 server. Affected file silcd/command.c.
2579 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Added _EXTRA_DIST SILC distribution variable to the
2582 distributions file. It is used to conditionally add extra
2583 files or directories to the specific distribution. Affected
2584 files ./prepare, Makefile.am.pre and distributions.
2586 Removed the `_' from the start of the distribution names.
2589 * Added README.WIN32 for instructions to compile the Toolkit
2592 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Fixed a double free in disconnection in the server. Affected
2595 file is silcd/server.c.
2597 * Fixed the lib/silcske/groups.c to work now also with GMP
2598 MP library. The string conversion did not work when using
2599 specific base and the base is indicated in the string as well.
2601 * Created win32/ directory which now includes MSVC++ specific
2602 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2603 It will appear only in the toolkit distribution
2605 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Changed the key material distribution function in case when
2608 the hash output is too short. The data is now concatenated
2609 a bit differently than it used to. Made the change to the
2610 SKE protocol specification.
2612 * Added better GMP detection to configure.in.pre. A patch
2615 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Fixed a minor bug in SKE that might cause some problem on
2618 some platforms. Affected file lib/silcske/silcske.c.
2620 * Added the cookie checking for initiator in the SKE. It checks
2621 that the responder returns the sent cookie unmodified. The
2622 affected file is lib/silcske/silcske.c. Added new SKE
2623 error type INVALID_COOKIE that can be sent during the
2624 negotiation. Fixed some memory leaks as well.
2626 * Added the "invalid cookie" error message to Irssi SILC client's
2629 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * Added `task_max' field to the SilcClientParams to indicate
2632 the maximum tasks the scheduler can handle. If set to zero,
2633 default values are used. Affected file lib/silcclient/silcapi.h.
2635 * Fixed memory leaks in silc_client_close_connection. Affected
2636 file lib/silcclient/client.c.
2638 * Added silc_client_del_client_entry to client library to free
2639 all memory of given client entry. Affected file is
2640 lib/silcclient/idlist.[ch].
2642 * Added new functions silc_client_del_channel and
2643 silc_client_del_server to delete channel and server entries.
2644 Affected file lib/silcclient/[silcapi.h/idlist.c].
2646 * Removed silc_client_del_client_by_id from silcapi.h.
2648 * Fixed the INFO command to return the server's own info
2649 correctly when querying by Server ID. Affected file is
2652 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Removed the non-blocking settings in WIN32 code in the
2655 silc_sock_[read/write] and added SleepEx instead. Affected
2656 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2657 of input data is now checked with FIONREAD and ioctlsocket.
2659 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Call silc_schedule_task_del_by_context in the
2662 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2663 Affected file lib/silccore/silcprotocol.c.
2665 * Call silc_protocol_cancel for active protocols in the
2666 silc_server_close_connection if the funtion
2667 silc_server_free_sock_user_data has not been called.
2668 Affected file silcd/server.c.
2670 * Generic tasks cannot be deleted using the del_by_fd
2671 task deleting function since generic tasks does not match
2672 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2674 * Added a notion to SILCOPER help file that the SILCOPER works
2675 only on router server, not on normal server.
2677 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Added for WIN32 support for the new scheduler as well.
2680 Affected file lib/silcutil/win32/silcwin32schedule.c.
2682 * Fixed the SHA1 implementation to work on various platforms.
2684 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2687 API. It is part of the scheduler now. Everything else is
2688 as previously but some functions has changed their names.
2689 Checkout the lib/silcutil/silcschedule.h for the interface.
2690 Updated all applications to use the new interface. Affected
2691 files are lib/silcutil/silcschedule.[ch].
2693 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Found a bug in the SKE implementation. The HASH value,
2696 specified by the protocol, was not computed correctly. The
2697 public key of the responder was not added to the computation
2698 even though it is mandatory. Affected file lib/silcske/silcske.c.
2699 This unfortunately causes incompatibilities with older
2700 clients and servers.
2702 * Added WIN32 specific network init and uninit functions:
2703 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2704 the Winsock2. Affected file lib/silcutil/silcnet.h and
2705 lib/silcutil/win32/silcwin32net.c.
2707 * Set the socket always to nonblocking mode on WIN32 after
2708 reading data or writing data. Affected file is
2709 lib/silcutil/win32/silcwin32sockconn.c.
2711 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Fixed various compilation problems under WIN32. Affected
2714 files lib/silcutil/win32/silcwin32thread.c and
2715 lib/silcutil/win32/silcwin32schedule.c.
2717 * Removed all _internal.h #includes from public header
2718 files. Internal headers must never be included from
2721 Removed also the lib/silcske/payload_internal.h file.
2723 * All include files that may be needed (public and some others
2724 included by the public headers) by application developers are
2725 now copied to the ./includes directory. It does not copy any
2726 internal headers. Affected file Makefile.defines.pre and all
2727 Makefile.am's under lib/ and subdirs.
2729 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Do not change the ~/.silc directory's permissions automatically.
2732 Affected file irssi/src/silc/core/clientutil.c.
2734 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Do not cancel the protocol in silc_server_close_connection
2737 it might cause recursion. Now cancelled in the function
2738 silc_server_free_sock_user_data. Affected file silcd/server.c.
2740 * Fixed the silc_server_remove_clients_by_server to regenerate
2741 the channel keys correctly finally. Added also new function
2742 silc_server_remove_clients_channels to actually do it.
2743 Affected file silcd/server.c.
2745 * Fixed the silc_server_new_channel to not crash by giving
2746 wrong router to the new channel. Affected file is
2747 silcd/packet_receive.c.
2749 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2752 which is given as argument to the silc_client_alloc now.
2753 It can be used to configure the client and set various parameters
2754 that affect the function of the client.
2756 * The USERS command in server did not check whether the channel
2757 is private or secret. Affected file silcd/command.c.
2759 * Added new argument to the USERS command in protocol specification.
2760 The USERS command now can take the channel name as argument
2761 as well. Added support for this in client and server and
2762 updated the protocol specs.
2764 * Completed the GETKEY command in client. It can be now used
2765 to fetch also servers public key not only some clients.
2766 Affected files lib/silcclient/command[_reply].c.
2768 * Added silc_client_get_server to return server entry by the
2769 server name. Affected files lib/silcclient/silcapi.h and
2772 * Redefined the IDENTIFY command in protocol specification to be
2773 more generic. It now can be used to query information about
2774 any entity in the SILC Network, including clients, servers and
2775 channels. The query may be based either the entity's name
2776 or the ID. Added support for this in both client and server.
2778 Affected files silcd/command.c and lib/silcclient/command.c
2779 and command_reply.c.
2781 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2782 the _from_client and _from_server functions. Affected file
2785 * Added silc_client_get_channel_by_id_resolve to the file
2786 lib/silcclient/silcapi.h to resolve channel information by
2787 its ID. Added also silc_client_get_channel_by_id that
2788 does not resolve it from the server.
2790 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Added SilcServerEntry context into the client library
2793 to represent one server. The INFO command now allocates
2794 these to save the resolved server info. For now on the
2795 client library will also keep information about servers,
2796 connected and resolved with INFO.
2798 The INFO command now allocates the SilcServerEntry context
2799 and saves the server info there. The COMMAND_REPLY in
2800 the INFO now returns the parameters to application in
2801 same order as defined in the protocol specification.
2803 The entries are cached in the client->server_cache.
2805 * The INFO command is now issued after received the Client ID
2806 from the server. Affected file lib/silcclient/client.c.
2808 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2809 to the application as the mode changer might be server.
2810 It is guaranteed that NULL is not returned anymore to the
2811 application. Affected file lib/silcclient/client_notify.c.
2813 The ID Type is now also passed to the application so that
2814 it can check whether the returned entry is SilcClientEntry
2817 Added new function silc_client_get_server_by_id to return
2818 the server entry by ID. Affected files are the
2819 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2821 * Do not create the channel in the Irssi SILC Client when issuing
2822 the JOIN command but when received the sucessful JOIN command
2823 reply. Otherwise the channel might get created even though we
2824 could not join it. The Affected file is
2825 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2827 * Fixed a channel joining bug in router. The router must also
2828 check the channel modes, invite and ban lists etc. when serving
2829 the JOIN command sent by normal server. Affected file is
2830 silcd/command.c. The router now resolves the client's
2831 information from the server who sent the JOIN command if it
2832 does not know it, and processes the JOIN command only after
2835 * Changed the SilcCommandCb to take new argument; void *context2.
2836 Affected file lib/silccore/silccommand.h
2838 The second argument in the command callbacks in the server now
2839 includes the SilcServerCommandReplyContext if the command was
2840 called as pending command callback from the command reply.
2841 Otherwise it is NULL. When called as pending the status of the
2842 command reply will be checked and if it was erronous the
2843 error will be sent to the original sender of the command.
2844 This way the client always receives the error messages even
2845 though the server was actually the one who received the error
2846 when it resent the command to router, for example. Affected
2847 files silcd/command[_reply].[ch].
2849 * Fixed sending WHOWAS command's error message to client if
2850 the requested client could not be found. It was missing.
2853 * Changed the CMODE and CUMODE commands reply arguments in the
2854 protocol specification. The Channel ID is now sent in both
2855 of the commands to identify the channel. Implemented this
2856 new feature to the client and server. Affected files
2857 lib/silcclient/command_reply.c and silcd/command.c.
2859 * Made better checks for invite and ban lists in the JOIN
2860 command in server. Affected file silcd/command.c.
2862 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * The server now performs the incoming host IP/DNS lookup
2865 using the silc_socket_host_lookup and thus does not block
2866 the server anymore. Affected file silcd/server.c.
2868 * Completed the multi-thread support for SILC Scheduler in
2869 the lib/silcutil/silcschedule.c.
2871 * Fixed the configure.in.pre to detect the pthread correctly
2874 * Fixed a deadlock in silc_task_queue_wakeup in the file
2875 lib/silcutil/silctask.c.
2877 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Added new function silc_schedule_wakeup that is used in
2880 multi-threaded environment to wakeup the main thread's
2881 schduler. It needs to be used when a thread adds a new task
2882 or removes a task from task queues. After waking up, the
2883 scheduler will detect the task queue changes. If threads
2884 support is not compiled in this function has no effect.
2885 Implemented the wakeup mechanism to both Unix and WIN32
2886 systems. Affected files are lib/silcutil/silcschedule.[ch],
2887 lib/silcutil/unix/silcunixschedule.c and the
2888 lib/silcutil/win32/silcwin32schedule.c.
2890 * Added new function silc_task_queue_wakeup to wakeup the
2891 scheduler by the specified task queue. Affected file
2892 lib/silcutil/silctask.[ch].
2894 * The silc_socket_host_lookup_start now wakes up the scheduler
2895 after adding the timeout task. Affected file is
2896 lib/silcutil/silcsockconn.c.
2898 * The silc_socket_host_lookup is synchronous now if the threads
2899 support is not compiled in. However, the callback is still
2900 called asyncronously through the scheduler, anyway. Affected
2901 file lib/silcutil/silcsockconn.c.
2903 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Added new function silc_socket_host_lookup to perform
2906 asynchronous IP and FQDN lookups for the socket connection.
2907 Affected files lib/silcutil/silcsockconn.[ch].
2909 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2912 that may or may not compile the mutex support in.
2914 Changed the silc_mutex_alloc interface. It allocates the
2915 mutex now to the sent pointer and returns TRUE or FALSE.
2917 Affected file lib/silcutil/silcmutex.h.
2919 * Wrote the SILC Task Queue interface to support multi-threads.
2920 Affected file lib/silcutil/silctask.[ch].
2922 * Wrote the SILC Scheduler to support multi-threads. Affected
2923 file lib/silcutil/silcschedule.c.
2925 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2928 in lib/silcutil/win32/.
2930 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2932 * Defined SILC Mutex API and SILC Thread API and implemented
2933 them for Unix. Affected files are
2934 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2935 lib/silcutil/unix/silcunixmutex.c and
2936 lib/silcutil/unix/silcunixthread.c.
2938 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Fixed the silc_server_remove_clients_by_server's channel
2941 key re-generation. The hash table handling was incorrect
2942 and would not work with many channels. Affected file is
2945 * Fixed some memory leaks around the server code.
2947 * Rewrote the silc_server_get_users_on_channel to support IPv6
2948 based Client ID's. Affected file silcd/server.c.
2950 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2951 specification. However, a separate document must be written
2952 to define the detailed signing procedure and the payload
2953 associated with the flag. Defined the flag to the
2954 lib/silccore/silcchannel.h as well.
2956 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Changed the dynamic tables to static size tables in the
2959 lib/silccrypt/silchmac.c.
2961 * Removed GCC dependencies from the code. A patch by cras.
2963 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Do not show the error "Error receiving packet bla bla"
2966 in server if it really was not an error (-2 means that reading
2967 is pending). Affected file silcd/server.c.
2969 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Fixed a possible crash in silc_server_remove_clients_by_server
2972 in silcd/server.c. Fixed there also some memory leaks.
2974 * Fixed the silc_idlist_replace_client_id. It could replace
2975 wrong key in the hash table. Affected file silcd/idlist.c.
2977 * Do not check whether there are global users on the channel
2978 if the channel->global_users is FALSE. Affected functions
2979 silc_server_remove_from_one_channel and
2980 silc_server_remove_from_channels in silcd/server.c. Also,
2981 do not check if the removed client is local as we can be
2982 sure that global client was not removed from the channel
2983 and checking for global users is not needed.
2985 * The silc_server_remove_clients_by_server now re-generates
2986 the channel keys correctly for those channels that had
2987 clients removed from them. Affected file silcd/server.c.
2989 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Found the reason of random crashes in the server. We weren't
2992 ignoring the SIGPIPE signal (which can be sent in write())
2993 and it crashed the server. Affected file silcd/silcd.c.
2995 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Assure that sock->user_data is not NULL in the function
2998 silc_server_packet_send in silcd/packet_send.c.
3000 * Disconnect the remote connection if it could not be added
3001 to any ID lists in the server. The affected file is
3004 * Check in silc_server_packet_send[_real/dest] that the
3005 socket is not disconnecting and ignore the data if it is.
3006 Affected file silcd/packet_send.c.
3008 * Define inline to __inline on native WIN32 compilation.
3009 Affected file includes/silcwin32.h.
3011 * Added some explicit type casts for inline code since MSVC
3012 require them. Affected files lib/silcutil/silcbuffer.h,
3013 lib/trq/silcdlist.h and lib/trq/silclist.h.
3015 * Print warning in log files from now on if the packet
3016 decryption fails. Affected file silcd/server.c.
3018 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Changed the `say' client operation's interface to accept
3021 new `type' argument to indicate the type of the message sent
3022 by the library. The application may filter the library's
3023 messages according the type. The affected file is the
3024 lib/silcclient/silcapi.h.
3026 * Added two new functions to lib/silcclient/silcapi.h:
3027 silc_client_del_client and silc_client_del_client_by_id.
3028 Affected file lib/silcclient/idlist.c.
3030 * Moved the clientincludes.h from includes/ to silc/ and
3031 serverincludes.h from includes/ to silcd/.
3033 * The modes for the CMODE and CUMODE are now passed as
3034 uint32 for application with COMMAND_REPLY. The affected
3035 file is lib/silcclient/command_reply.c.
3037 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * /WHOIS without arguments shows client's own information.
3040 Affected file lib/silcclient/command.c.
3042 * Changed PING to not accept any arguments. The specs
3043 says that client can ping only the connected server so
3044 requiring an argument is not needed. Affected file is
3045 lib/silcclient/command.c.
3047 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Fixed a fatal bug in private message sending and reception
3050 encryption and decryption when using private message keys.
3051 The implementation was incorrect and did not follow the
3052 specification. It causd that some of the message were
3053 lost since it did not use the sending and receiving keys
3054 as the protocol suggests. This has been fixed and will cause
3055 incompatibilities with older clients when sending private
3056 message encrypted with private message keys. Affected files
3057 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3058 and various other in Irssi SILC Client.
3060 Added `responder' boolean argument to the functions
3061 silc_client_add_private_message_key[_ske] to indicate when
3062 the key is added as responder or initiator of the key
3065 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Removed the silc_ske_check_version function and created
3068 a SilcSKECheckVersion callback. Added also a function
3069 silc_ske_set_callbacks that is now used to set all SKE
3070 callbacks. The callback functions are not given to
3071 the SKE functions anymore, but this function is used to
3074 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3076 * Added `silc_version' argument to the silc_client_alloc
3077 to define the version of the application for the library.
3078 The library will use the version string to compare it
3079 against the remote host's (usually a server) version
3080 string. Affected file lib/silcclient/silcapi.h
3082 * Added the KE protocol context to Key Agreement context
3083 in client library so that we can abort the SKE if it
3084 is in process when we get timeout. Affected file is
3085 lib/silcclient/client_keyagr.c.
3087 * Do not resolve the client ID forever if it returns in the
3088 first time that such client does not exist. This was done
3089 for example with private message. Affected file is
3090 lib/silcclient/client_prvmsg.c.
3092 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3094 * Do not add regex.h for WIN32. The affected file
3095 includes/silcincludes.h.
3097 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3098 not work yet 100%. It generates the DLL's automatically
3099 when compiling with --with-win32 under cygwin.
3101 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * lib/contrib/regex.c is not compiled on WIN32.
3105 * Added silc_net_get_socket_opt function to the
3106 lib/silcutil/silcnet.h.
3108 * Added includes/silcwin32.h for WIN32 specific includes
3111 * Do not use ptime structure or any of the posix process
3112 functions on WIN32 in lib/silccrypt/silrng.c.
3114 * Added silc_gettimeofday to provide generic function
3115 for struct timeval on all platforms. Added the function
3116 to lib/silcutil/silcutil.h.
3118 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3121 library as they clearly belong there. As a plus side we
3122 can make the actual socket connection routines platform
3125 Added also new generic function silc_socket_read and
3126 silc_socket_write (that used to be silc_packet_[read/write].
3127 The implementation of these are platform specific.
3129 * Added WIN32 specific routines of silc_socket_[read/write]
3130 to lib/silcutil/win32/silcwin32sockconn.c.
3132 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Added preliminary support for native WIN32 compilation under
3135 cygwin (using the -mno-cygwin option for GCC) to the
3136 ./configure.in.pre. The --with-win32 now prepares the
3137 compilation for native WIN32.
3139 * Rewrote the SILC Scheduler interface in the file
3140 lib/silcutil/silcschedule.h. The scheduler is now context
3141 based and does not have anymore any global static scheduler.
3142 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3143 and created lib/silcutil/win32 directory for WIN32 based
3146 * Added Unix specific network routines to the
3147 lib/silcutil/unix/silcunixnet.c and the old
3148 lib/silcutil/silcnet.c includes now only generic routines.
3150 Added WIN32 specific network routines to the
3151 lib/silcutil/win32/silcwin32net.c.
3153 * Added Unix specific utility functions from the
3154 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3156 * Added WIN32 SILC Scheduler to the file
3157 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3160 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Do not handle JOIN notify in the server if the target client
3163 is not registered (idata->registered == FALSE). The affected
3164 file is silcd/packet_receive.c.
3166 * Update the nickrec->founder in event_cumode in the Irssi SILC
3167 client. Affected file irssi/src/silc/core/silc-channels.c.
3169 * Fixed the CUMODE_CHANGE notify handling in the server when
3170 server and router are announcing their clients on channels.
3171 Now the mode changes are saved and notified correctly. The
3172 affected file is /silcd/packet_receive.c.
3174 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3175 They really did not replace the cache entry in the ID Cache.
3176 Now they do that. Affected file silcd/idlist.c.
3178 * Fixed the KICK notify handling in the Irssi SILC client to
3179 update the channel records so that the kicked client does not
3180 appear to be on the channel. The affected file is
3181 irssi/src/silc/core/silc-channels.c.
3183 * Always update the conn->current_channel when executing command
3184 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3186 * Fixed the KILL notify handling in Irssi SILC client to remove
3187 the killed client on all channels.
3189 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Fixed the silc_parse_command_line to remove extra spaces
3192 from the start and end of the arguments. Affected file is
3193 lib/silcutil/silcutil.c.
3195 * Cancel and free any active protocol in the function
3196 silc_server_close_connection. Affected file silcd/server.c.
3198 * Cancel and free any active protocol in the function
3199 silc_client_close_connction. Affected file is
3200 lib/silcclient/client.c.
3202 * Do not execute the KILL command for clients that are in
3203 history (ie. they are not in the network). Affected file is
3206 * Fixed KILL notify handling, client does not crash anymore.
3207 Affected file irssi/src/silc/core/silc-channels.c.
3209 * Reduced the default packet buffer size from 2048 to 1024 in
3210 lib/silccore/silcpacket.c.
3212 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3213 counter to the SKE context that is incresed when the SKE library
3214 performs async operation outside the library. If the outside
3215 process frees the SKE context and FREED status will be set
3216 and the library will detect after the sync operation that the
3217 libary is freed. The affected files are
3218 lib/silcske/silcske[_status].[ch].
3220 * Resolve the client entry information in the function
3221 silc_client_channel_message to assure that NULL pointer is not
3222 passed as client entry to the application. */
3224 * Fixed the task timeout calculation to assure that there is
3225 never negative timeouts. The affected file is
3226 lib/silcutil/silcschedule.c.
3228 * Fixed the channel user mode notification sending in server.
3229 It was sent point-to-point to the router (or to server by router)
3230 but it needs to be destined to a channel. The routines now
3231 supports sending the channel user mode notifys to the channels
3232 when announcing clients and channels. Affected files are
3233 silcd/server.c and silcd/packet_receive.c.
3235 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3236 It did not actually replace the old channel entry in the cache.
3237 Affected file lib/silcclient/client_notify.c.
3239 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Fixed a possible crash in silc_packet_send_prepare. It now
3242 assures always that there is enough space in the buffer and
3243 at the tail area of the buffer (for MAC).
3245 Fixed the inbound buffer reallocation in silc_packet_read.
3246 It was old code and did not handle the reallocation correctly.
3249 The affected file is lib/silccore/silcpacket.c.
3251 * Fixed buffer overflow in silc_parse_nickname in the file
3252 lib/silcutil/silcutil.c.
3254 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * make install generates new server keys only if there is not
3259 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3262 Added check that if the NOREPLY is set then we will not send
3263 the away message. This avoids infinite loop of away messages
3264 if both clients are away. The affected file is
3265 lib/silcclient/client_prvmsg.c.
3267 * Fixed client crash if /NICK was given without arguments.
3268 Affected file lib/silcclient/command.c.
3270 * Server does not send the invite list in INVITE command back
3271 to the client if the list was not altered. Added this notion
3272 to the protocol spec as well. Affected file silcd/command.c.
3274 Fixed possible crash in INVITE command by checking the
3275 value of silc_server_get_client_route command.
3277 * Fixed the INVITE notify type handling. The arguments are now
3278 taken in correct order and client does not crash. The affected
3279 file is irssi/src/silc/core/silc-channels.c.
3281 Removed the "Inviting xxx to channel" message from the
3282 client library away and let the application handle it.
3283 Affected file lib/silcclient/command.c. Added that message
3284 to Irssi SILC client's message formats.
3286 * Fixed CMODE command crash in client. It now checks the
3287 amount of arguments correctly and does not crash. The affected
3288 file is lib/silcclient/command.c.
3290 * Do not create new channel automatically in silc_channels_join
3291 but check whether the channel by that name already exists.
3292 Affected file irssi/silc/core/silc-channels.c.
3294 * Do not send the SERVER_SIGNOFF to router if the disconnected
3295 entity was the router. Affected file silcd/server.c.
3297 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3298 SILC client as it was missing from there.
3300 Added the handling of the KICK notify to the Irssi SILC client
3301 as it was missing. Added "you have been kicked" message to
3302 Irssi SILC client's message modules formats.
3304 Added the handing of the KILL notify to the Irssi SILC client
3305 as it was missing. Added the kill message module formats
3308 The affected file is irssi/src/silc/core/silc-channels.c.
3310 * The router did not save the channel mode the server announced.
3311 Affected file silcd/packet_receive.c.
3313 * Fixed a possible crash in INFO command in server. If the
3314 server did not provide the server info it crashed. Affected
3315 file silcd/command.c.
3317 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Fixed the GETKEY command in the server to check also the
3320 global list. Otherwise the GETKEY would not work correctly
3321 in normal SILC server. Affected file silcd/command.c.
3323 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Fixed GETKEY crash, it crashed if the command did not succseed.
3327 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3330 is now real and not just an macro interface to GMP.
3332 Removed the entire GMP from the source tree and imported new
3333 NSS MPI library instead. Reason for removing GMP is that it is
3334 extremely large and compiles extremely slow. The NSS MPI
3335 is only a few files and compiles in less than 10 seconds.
3336 The speed is also about the same as GMP. The MPI is imported
3337 to lib/silcmath/mpi.
3339 If the system has GMP installed we will still use the GMP.
3340 If it is not then the NSS MPI will be compiled.
3342 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Merged a long nickname (127 characters long) crash bugfix from
3345 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3347 * Merged a freed memory reference bugfix from Irssi CVS tree.
3348 Affected file irssi/src/core/commands.c.
3350 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Added the server's public key sving and verification to the
3353 server when performing the SKE. This was missing and the
3354 remote server's (or router's) public key was accepted without
3355 checking whether we have it previously or trust it at all.
3356 Affected file silcd/protocol.c.
3358 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Check in the silc_server_timeout_remote if protocol is active
3361 and make sure that the protocol's final callback is called so
3362 that all memory if freed. Affected file silcd/server.c.
3364 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * silc_server_whois_send_reply crashed the server if the nickname
3367 was 127 characters long. Affected file silcd/command.c.
3369 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Added sanity check to the silc_server_new_client. If the hostname
3372 is provided inside username then check that the provided hostname
3373 really is the same as the resolved one. If the hostname was not
3374 resolved then check it from the public key. Affected file is
3375 silcd/packet_receive.c.
3377 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3378 if the server disconnected us and the connection is not valid
3379 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3381 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3382 the library to the lib/silcutil/silcutil.[ch].
3384 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Close log file after open. Affected file
3387 lib/silcutil/silclog.c.
3389 * Check whether sock == NULL in silc_client_send_packet and return
3390 if it is. Affected file lib/silcclient/silcclient.c.
3392 * Check rec->entry == NULL in the Irssi SILC Client before
3393 sending the channel message. Affecte file is
3394 irssi/src/silc/core/silc-servers.c.
3396 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Merged a splitted window bugfix from Irssi CVS tree. The
3399 affected file is irssi/src/fe-text/textbuffer-view.c.
3401 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3402 It did not print nickname.
3404 * Improved the distributions system a bit.
3406 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3409 irssi/src/fe-text/gui-window.c.
3411 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3412 to in-active server. The affected file is
3413 irssi/src/silc/core/client_ops.c.
3415 * Resolve the client in USERS command reply if the entry does
3416 not have username resolved. The affected file is
3417 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3418 command to WHOIS command to really resolve stuff. The USERS
3419 is not used any more in any critical section so WHOIS can
3420 be used even though it might be slower than IDENTIFY.
3422 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3425 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Changed the protocol API a bit more consistent in the
3428 lib/silccore/silcprotocol.[ch].
3430 * Changed the following headers to ROBODoc format:
3432 lib/silccore/silcpayload.h
3433 lib/silccore/silcprotocol.h
3434 lib/silccore/silcsockconn.h
3436 All core library headers are now formatted.
3438 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Fixed a bug in Irssi SILC client; do not show that you are
3441 server/router operator if you really are not. Affected file is
3442 irssi/src/silc/core/client_ops.c.
3444 * Renamed silc_command_free_payload to silc_command_payload_free.
3445 Affected file lib/silccore/silccommand.h
3447 * Added silcmath.h to include the prototoypes of various routines
3448 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3451 * Changed the following headers to ROBODoc format:
3453 lib/silccore/silcchannel.h
3454 lib/silccore/silccommand.h
3455 lib/silccore/silcid.h
3456 lib/silccore/silcidcache.h
3457 lib/silccore/silcmode.h
3458 lib/silccore/silcnotify.h
3459 lib/silccore/silcpacket.h
3460 lib/silcmath/silcmath.h
3462 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added checking to the server code not to start the server if
3465 ciphers and stuff are not configured properly. Affected files
3466 silcd/serverconfig.[h] and silcd/server.c.
3468 * Changed the layout of the header files of the public interfaces
3469 in the SILC libraries. The new layout supports ROBODoc
3470 documentation tool (and some others) so that it is easy to create
3471 a library reference manual. All the other headers and source
3472 code must still follow the CodingStyle document. Also source
3473 code must not include these ROBODoc stuffs, only the headers.
3474 Furthermore, all public interface headers must now be named
3475 by using `silc' prefix, example: silcapi.h, silccipher.h.
3476 Some files were renamed due to this. All the other headers
3477 must not be used as public interfaces. I will update the
3478 CodingStyle document later. Changed following headers, so far:
3480 lib/silcclient/silcapi.h
3481 lib/silccore/silcauth.h
3482 lib/silccore/silcprivate.h
3483 lib/silccrypt/silcdh.h
3485 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Removed silc_client_packet_send_flush from the client library
3490 as it is not needed. Affected file lib/silcclient/client.[ch].
3492 * Added printing of message of unresolved authentication method
3493 to the Irssi SILC client. Added it to the module formats.
3494 Removed the same message from the client library.
3496 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Added new distribution feature, DISTLABEL. Every distribution
3499 can define own preprocessor label that can be used in the
3500 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3501 file distributions, acconfig.h.pre and prepare.
3503 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added Makefile.defines_int to include the actual definitions
3506 for Makefile.defines.in. Tested the new distribution system,
3507 created distributions and tested installation.
3509 * Added AWAY message printing to the Irssi SILC client. Added
3510 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3512 * Added SCONNECT command to call the SILC's CONNECT command.
3513 Cannot use CONNECT directly since Irssi uses that internally.
3514 Affected file irssi/src/silc/core/silc-servers.c.
3516 Added ACTION local command. It is same as ME command but takes
3517 the channel as mandatory argument.
3519 Rewrote some of the Irssi's help files to suite for SILC
3522 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added Makefile.defines[.in] that should for now on be included
3525 in all Makefile.am file in the source tree. That file includes
3526 all common compilation definitions for SILC source tree.
3528 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Minor changes to the ./prepare script to change the package
3531 name according the distribution name to the configure.in.
3533 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Created new distribution system. Added file `distributions'
3536 that defines all the distributions that can be created out of
3537 the SILC source tree. The ./prepare script now reads that
3538 file to determine how to prepare the distributions. The
3539 first argument to the ./prepare is the name of the distribution
3540 and second is the version of the distribution. If given
3541 without arguments it creates the default (toolkit) distribution
3542 with the default version (defined in ./prepare).
3544 All Makefile.am files that are subject to the distributions
3545 are now named as Makefile.am.pre. These are ./Makefile.am
3546 and lib/Makefile.am. Others may be changed later.
3548 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Added invite list, ban list, some key management and connection
3551 error message printing to module formats in the Irssi SILC client.
3553 * Added new silc_client_set_away_message to set the away message
3554 that is back to the person who sent private message. The
3555 affected file lib/silcclient/silcapi.h and the
3556 lib/silcclient/client_prvmsg.c.
3558 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Fixed the private message sending in the Irssi SILC client,
3561 added local command KEY to the Irssi SILC client.
3563 Added key management and key agreement message formats to the
3564 irssi/src/fe-common/silc/module-formats.[ch].
3566 Added USERS (alias WHO) printing, server/router operator
3567 indication and LIST command printing to the module formats.
3569 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Fixed channel joining notify handling, cumode notify handling
3572 from Irssi SILC client.
3574 * Added SILC specific module-formats to the Irssi SILC client so
3575 that SILC specific message hilighting, colors etc is possible.
3576 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3578 Added channel mode, channel user mode, actions, notices,
3579 whois and whowas printing to the the module-formats.c.
3581 * Fixed a bug in channel deletion in the server. The channel
3582 is not left to the cache even if the channel founder auth mode
3583 is set when there are no users anymore on the channel. Affected
3584 file silcd/server.c.
3586 * The silc_net_localhost now resolves the entire hostname including
3587 the domain name. Affected file lib/silcutil/silcnet.c.
3589 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Changed the ask_passphrase client operation to be ascynchronous.
3592 It has now a completion callback and a context that the
3593 application must call after it has got the passphrase from
3594 the user. Affected files lib/silcclient/silcapi.h,
3595 lib/silcclient/protocol.c, lib/silcclient/command.c and
3598 Added SilcAskPassphrase callback that the application calls
3599 to deliver the passphrase to the library.
3601 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3602 The public key verification and especially a certificate
3603 verification is asynchronous procedure.
3605 Added new SILC_SKE_STATUS_PENDING status to indicate the
3606 request is pending and a callback will be called to finalize
3609 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3610 indicate that remote end did not send its public key (or
3611 certificate), even though we require it. Added check for this
3612 condition in the SKE. This was a security bug, now fixed.
3614 Defined new SilcSKEVerifyCbCompletion callback that is called
3615 when the verification process is completed.
3617 The affected files lib/silcske/silcske_status.h and
3618 lib/silcske/silcske.[ch].
3620 * Changed the verify_public_key client operation to be async
3621 as well. Defined SilcVerifyPublicKey callback that is used to
3622 indicate the success of the public key verification process.
3624 Changed the server and client to use the new async client
3627 * Changed the Irssi SILC client's internal scheduler to be called
3628 twice as many times as it used to be. As a result the client
3629 should be a bit faster now. Affected file is
3630 irssi/src/silc/core/silc-core.c.
3632 * Added support to Irssi SILC client of asynchronous public key
3633 verification and passphrase inquiry. Affected file is
3634 irssi/src/silc/core/silc-core.c.
3636 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Do not say "You have left channel %s" in client library.
3639 Moved it to the application. Affected files are
3640 lib/silcclient/command.c and silc/client_ops.c.
3642 * Fixed silc_client_get_clients. Command context was not
3643 duplicated and was freed memory in the callback. Affected
3644 file lib/silcclient/idlist.c.
3646 * Do not say "you are now talking..." on JOIN command in the
3647 client library. The appliation must handle it.
3649 * Do not say ".. changed topic to" in command reply in the
3650 client libary. The application must handle it.
3652 * Fixed TOPIC command sending in the client library.
3654 * Fixed a memory leak in silc_client_command_free in the file
3655 lib/silcclient/command.c.
3657 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Imported a modified version of Irssi client to the source tree.
3660 The Irssi will be used to create a new client called
3661 Irssi SILC. Imported to irssi/.
3663 Added silc_core_init_finish function to the Irssi. Affected
3664 file irssi/configure.in.
3666 A lot changes in the Makefile.ams around the irssi tree.
3668 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Do not rehash if the new size is same as the old size of the
3671 hash table, in the silc_hash_table_rehash*. The affected file
3672 lib/silcutil/silchashtable.c.
3674 * Replaced hash_table_del_by_context calls from the server
3675 (when channel->user_list and client->channels) to the
3676 hash_table_del as it is sufficient and faster.
3678 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added silc_hash_table_list, silc_hash_table_get and the
3681 SilcHashTableList structure to provide an alternative way to
3682 traverse the hash table. The affected files are
3683 lib/silcutil/silchashtable.[ch].
3685 * Changed the server's idlist routines to use the hash table
3686 routines to optimize the code.
3688 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Replaced the client entry's `channel' list and channel entry's
3691 `user_list' list to hash tables for optimized lookup. Changed
3692 the code to use the hash table interface around the code.
3693 Affected file lib/silcd/idlist.[ch].
3695 * Added `auto_rehash' boolean argument to the function
3696 silc_hash_table_alloc to indicate whether the hash table should
3697 auto-rehash when it thinks is appropriate time. It will
3698 increase the hash table size if the there is twice as much
3699 entries in the table than the size of the table, and will
3700 decrease the size if there are twice as less entries than
3701 the size of the table.
3703 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3707 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * silc_idcache_purge_by_context deletes the entry now by context
3710 as it is supposed to do. Affected file lib/silccore/idcache.c.
3712 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3713 client is not anymore valid (WHOWAS givens the info) and not
3714 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3716 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Removed the `data' and `data_len' arguments from the ID Cache
3719 interfaces and added `name' argument. ID Cache does not handle
3720 anymore the binary data only a names associated with given ID.
3722 * When hashing a Client ID with silc_hash_id the entire ID is
3723 not hashed anymore, instead only the hash of the Client ID is
3724 hashed. This way we can access the Client ID from the cache
3725 with Client ID but with the hash of the ID (which is a hash of
3726 the nickname) as well without any difference in performance.
3728 Added also silc_idcache_find_by_id_one_ext to do one on one
3729 searching when we have the actual ID. Added also function
3730 silc_hash_client_id_compare. The affected files are
3731 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3733 * When hashing the name associated with a ID it is always done
3734 in lowercase. This way we can access the cache without worrying
3735 about case-sensitivity, even though, for example nicknames are
3738 * Fixed a bug in server with channel message sending. It put
3739 wrong ID type as destination ID. The affected file
3740 silcd/packet_send.c.
3742 * silc_idcache_del_by_context now deletes from all hash tables
3743 by context. Affected file lib/silccore/idcache.c.
3745 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Changed the client library to use the new ID Cache interface.
3748 Changes around the source tree.
3750 * Added silc_hash_table_rehash_ext to rehash with specific
3751 hash function. Affected file lib/silcutil/silchashtable.[ch].
3753 * Added silc_hash_string_compare to compare two strings in the
3754 hash table. Affected file lib/silcutil/silcutil.[ch].
3756 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added new function silc_idcache_del_by_context into the
3759 lib/silccore/idcache.[ch].
3761 * Changed the server's ID list routines to use the new ID Cache
3762 interface. Changes around the source tree.
3764 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added silc_hash_table_del[_by_context]_ext functions in to the
3767 lib/silcutil/silchashtable.[ch].
3769 Removed silc_hash_table_find_all* routines and added new
3770 silc_hash_table_find_foreach to replace them.
3772 Added silc_hash_table_replace_ext function as extended
3773 replacing function. Separated the simple hash table interface
3774 from the extended hash table interface in the file
3775 lib/silcutil/silchashtable.h.
3777 * Fixed minor bugs and changed it to use some of the new
3778 hash table functions in lib/silccore/idcache.c
3780 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Added new function silc_hash_table_find_all to return all keys
3783 in the hash table by the specified key. As the hash table is
3784 collision resistant it also makes it possible to have several
3785 duplicate keys in the hash table. This function may be used to
3786 find all of the keys from the hash.
3788 Added user_context arguments to the SilcHashFunction,
3789 SilcHashCompare and SilcHashDestructor to deliver user specified
3792 Added new fuctions silc_hash_table_find[_all]_ext to do
3793 extended lookup with specified hash and compare functions and
3794 specified user contexts.
3796 Added new function silc_hash_table_add_ext to add the key
3797 with specified hash function and user context.
3799 Added new function silc_hash_table_foreach to traverse all
3800 entrys in the hash table. Added SilcHashForeach callback
3803 Added new function silc_hash_table_del_by_context to delete
3804 the entry only if the context associated with the key matches.
3806 Affected files are lib/silcutil/silchashtable.[ch].
3808 * Removed silc_hash_[server/client/channel]_id and added just
3809 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3810 silc_hash_id_compare to compare two ID's using as the hash table
3811 comparison function. Added also silc_hash_data to hash
3812 binary data and silc_hash_data_compare to compare it.
3814 * Removed silc_idlist_find_client_by_hash as it is not needed
3815 anymore. Affected file silcd/idlist.[ch].
3817 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3818 to use internally the SilcHashTable. The new ID Cache is a lot
3819 faster than the old one. Some of the ID Cache interface was also
3820 rewritten and obsolete and stupid functions were removed.
3822 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Added entry_count field to the SilcHashTable to keep the number
3825 of the entries in the table. Implemented the function
3826 silc_hash_table_rehash. Added new function
3827 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3829 Fixed a minor bug in silc_hash_table_free.
3831 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3832 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3833 into the lib/silcutil/silcutil.[ch].
3835 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Implemented a collision resistant hash table into the
3838 lib/silcutil/silchashtable[ch]. See the header and the source
3839 for the SilcHashTable API.
3841 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Merged dotconf version 1.0.2 into lib/dotconf.
3845 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Do not compile anything in lib/silcsim/* if the SIM support
3848 is not enabled. The tree should now compile without problems
3851 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Compiled the SILC under cygwin. Compiled and tested briefly
3854 without problems. More tests needed. The SIMs didn't compile
3857 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3859 * Fixed possible crash in silc_get_username in the
3860 lib/silcutil/silcutil.c.
3862 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Fixed a va_arg in silc/client_ops.c.
3866 * Oops, RC5 routines were named AES and caused some problems
3867 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3869 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added new SilcIDIP structure into the lib/silccore/id.h and
3872 replaced the old `ip' fields from all SILC ID's to that type.
3873 This is a step towards IPv6 support.
3875 The silc_id_get_len takes now the ID as an extra argument.
3876 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3877 both IPv4 and IPv6 based ID's.
3879 The affected files are lib/silccore/id.[ch] and other files
3880 around the tree using these routines.
3882 * Removed the ID length arguments in server from various
3883 silc_server_send_notify_* routines -> they are not needed
3886 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Fixed memory leak in silc_encode_pem_file in the file
3889 lib/silcutil/silcutil.c.
3891 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Check minor version as well in the SKE. Affected files are
3894 silcd/protocol.c and lib/silcclient/protocol.c.
3896 * Added --identifier option to the server so that an identifier
3897 can be when creating the public key for the server. Affected
3898 file is silcd/silcd.c.
3900 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3901 lib/silccrypt/silcpkcs.c.
3903 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Register default ciphers and stuff when using -C option with
3906 the server. Affected file sildc/silcd.c.
3908 * Put back the servers public key filename format, it is better
3909 than the new one. For now, the client keys are saved with the
3910 new filename format. The affected file silc/client_ops.c.
3912 * Implemented the Cipher API for the rest of the ciphers that
3913 did not implement it or implemented it the wrong way.
3915 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Register default ciphers and stuff when using the -S option
3918 in the client. Affected file silc/silc.c. Same also when
3919 creating new key pair with -C option.
3921 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Fixed the silc_verify_public_key client operation function to
3924 save the public keys differently. The fingerprint is now
3925 used as filename and not the hostname. This way also the
3926 client keys are saved uniquely and not with hostnames. The
3927 affected file is silc/client_ops.c.
3929 * Trimmed the silc_hash_fingerprint function to remove extra
3930 whitespaces from the end of the fingerprint. The affected
3931 file is lib/silccrypt/silchash.c.
3935 * Added silc_cipher_register_default function to register all
3936 default ciphers. It can be used when configuration files
3937 does not exist and the application does not want any specific
3938 ciphers in any specific order.
3940 The SilcDList is now used as silc_cipher_list dynamically
3941 allocated cipher list. Removed the static list all together
3942 and now all ciphers must be allocated to the dynamic list.
3943 The silc_cipher_alloc routine was changed to check only the
3946 All silc_cipher_* routines that used to return int returns
3949 The affected files lib/silccrypt/silccrypt.[ch].
3951 * The same thing was done to silc_hash_* as for silc_cipher_*
3952 routines. Affected files lib/silccrypt/silchash.[ch].
3954 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3955 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3956 Added also silc_pkcs_[un]register[_default] functions.
3957 Removed the data_context from the PKCS API.
3959 * Added silc_hmac_register_default function to register default
3960 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3961 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3962 to unregister all hmacs at once.
3964 * Register the default ciphers, hash functions, PKCSs and HMACs
3965 if client's configuration file does not exist. The affected
3968 * The client did not load the hash functions from the SIM
3969 modules at all. Added support for this. Affected file is
3970 silc/clientconfig.c.
3972 * When decoding public key with silc_pkcs_public_key_decode, check
3973 the supported algorithm only if PKCS are registered. Affected
3974 file lib/silccrypt/silcpkcs.c. The same was done with the
3975 silc_pkcs_private_key_decode.
3977 * Fixed the SILC List routines to keep the list always in order.
3978 It used to change the list's order when traversing the list but
3979 not it preserves the order. Affected file lib/trq/silclist.h.
3981 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Added the client library to use the SilcSocketConnection's
3984 reference counter (by silc_socket_dup) to prevent the bug that
3985 the socket object may be freed underneath async operation.
3987 * The name resolv library checking fixes in the configure.in.pre.
3990 * Created new version of the protocol drafts for future
3991 development. The -03 drafts are the ones that will be changed
3992 in the trunk now and the -02 will remain as they are.
3994 * Send list of CUMODE notifys to the router when announcing
3995 the channel users to the router. Affected file silcd/server.c.
3996 If the router receiving channel founder CUMODE for a channel
3997 that already has channel founder it will send CUMODE notify
3998 to the sender to remove the channel founder rights from the
3999 announced client. Affected file silcd/packet_receive.c.
4001 * The CUMODE notify may now use Server ID as well as the entity
4002 who changes the mode. Updated protocool specs.
4004 * Updated INSTALL and README files.
4006 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * New web pages in the http://silc.pspt.fi. The pages was
4013 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Implemented the [DenyConnectin] config section in the server.
4016 Added silc_server_config_denied_conn to check whether incoming
4017 connection is denied. Affected file silcd/serverconfig.[ch].
4019 * Do not check the ports when checking the incoming configuration
4020 data if the port is 0, meaning any. Affected file is
4021 silcd/serverconfig.c.
4023 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed buffer overflow in silc_string_compare in the file
4026 lib/silcutil/silcutil.c.
4028 * Fixed double free in silc_server_command_leave in the file
4031 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Fixed the version checking in the server. Affected file is
4036 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed the configuration data fetching when accepting new
4039 connections in the server. Affected file silcd/server.c.
4041 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added `sender_entry' argument to the function
4044 silc_server_packet_relay_to_channel so that we can check
4045 whether some destination actually belongs to the same route
4046 the sender belongs (ie, we must not resend the packet to the
4047 sender). Affected file silcd/packet_send.[ch].
4049 * Added `servername' field to the SilcClientEntry in the server
4050 to hold the name of the server where client is from. Affected
4051 file is silcd/idlist.h.
4053 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Moved the channel message encrypting in the router betwen
4056 router connections from silc_server_channel_message to the
4057 silc_server_packet_relay_to_channel since we want to check
4058 whether we have anybody channel before encrypting anything.
4059 Affected files silcd/packet_[receive/send].c.
4061 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Fixed the [AdminConnection] server config section to support
4064 multiple entries. Affected file silcd/serverconfig.c.
4066 * Added support into the server to check the validity of the
4067 incoming connection before executing any KE or authentication
4070 * The connection configuration is now saved to the KE and
4071 connection auth protocol contexts and not fetched anymore in
4072 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4074 * The local hosts listenning address and port is also resolved
4075 now when starting the server. We want to have the socket object
4076 to include the real address and port for the listener. Added
4077 new function silc_net_check_local_by_sock into the files
4078 lib/silcutil/silcnet.[ch].
4080 * Fixed a broadcast bug in server -> do not broadcast if we
4083 * Fixed a routing bug. Do not route broadcast packets ever.
4084 Broadcast packets must be processed always and not routed since
4085 they may be destined to some other host than yourself and thus
4086 would get routed without no good reason. Affected file is
4089 * Added function silc_server_config_is_primary_route to check
4090 whether primary router connection has been configured (a router
4091 configuration that we are initiating). If there is not, we
4092 will assume that there is only two routers in the SILC network
4093 and we will use the incoming router connection as our primary
4094 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4096 * Changed the order of the broadcasting. Broadcast _after_ the
4097 packet has been processed not before. Affected file is
4100 * Fixed a [ClientConnection] parsing bug. The port was never
4101 parsed correctly thus resulting to port 0. Affected file
4102 silcd/serverconfig.c.
4104 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4105 argument and did not set the broadcast packet flag. Affected
4106 file silcd/packet_send.c. Fixed same bug in the function
4107 silc_server_send_notify as well.
4109 * If we receive NEW_ID packet for our own ID in the server, ignore
4112 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Removed the nickname from the Private Message Payload.
4117 Updated the code and the protocol specs.
4119 * Updated protocol specs for submitting to the IETF.
4121 * Tweaked the Random Number Generator a bit. Affected file
4122 lib/silccrypt/silcrng.c. Exported a new function
4123 silc_rng_[global]_add_noise which can be used to add more
4126 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Do not parse packets with different timeout when protocol
4129 is active -> may cause problem with rekey. Affected file
4132 * When server receives signoff notify it must not create
4133 new channel key if the client is on any channels since the
4134 sender of the signoff notify will create it.
4136 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added printing of error messages during SKE protocol from the
4139 failure packet sent by server during SKE. Affected file
4142 * Removed the client's failure_callback handling with timeout
4143 and handle it immediately when received.
4145 * The SKE library returned wrong type in SUCCESS and FAILURE
4146 packets. They must be 32 bit MSB not 16 bit MSB.
4148 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Ok, rewrote the logic of the re-key and now it seems to work.
4151 I tested it on high traffic with frequent re-keys without
4152 problems. Added hmac_receive (and renamed hmac to hmac_send)
4153 in SilcClientConnection in lib/silcclient/client.h and
4154 in SilcIDListData in silcd/idlist.h. Also, removed the
4155 SilcPacketParserContext's cipher and hmac fields as they are
4156 not needed anymore and actually caused some problems when
4157 the ciphers and hmac's changed underneath the packet parser.
4159 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * If re-key protocol is active then process the incoming packets
4162 synchronously since we must assure that icoming packets encrypted
4163 with the old key is processed before the new keys is set to
4164 use. This is true other packets than for REKEY packets.
4165 Affected file silcd/server.c. The same was done to client library
4166 as well, affected file lib/silcclient/client.c.
4168 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Fixed bug in client and server to accept the force send if
4171 the packet is send from silc_[server/client]_packet_process
4172 function. Otherwise the packets are never delivered, oops.
4174 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Disable force sending of packets when REKEY protocol is active.
4177 We must assure that no packet is sent directly when rekey is
4178 performed. All packets must be sent through packet queue.
4179 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4180 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4181 function is silc_[server/client]_packet_send_real to check
4184 * Replaced the SIM paths from example config files to
4185 /usr/local/modules. Also, make install creates now
4186 /usr/local/silc/logs directory to hold all the SILC server
4189 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Made the configure.in.pre work on Solaris. Patch by salo.
4193 * Made all ciphers compatible with non-x86 machines. Defined
4194 CBC mode macros into lib/silccrypt/ciphers_def.h.
4196 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Fixed the make install.
4200 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * When MAC computation fails the silc_packet_decrypt returned 0
4203 even though it was supposed to return -1. Fixed this. The
4204 affected file is lib/silccore/silcpacket.c.
4206 * Do not replace the config files in /etc/silc (in make install)
4207 if they already exist. Affected file ./Makefile.am.
4209 * Do not send re-key packets immediately but through packet queue.
4210 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4212 * Changed silc_net_check_host_by_sock to return FALSE if the
4213 IP/DNS could not be resolved. Though, it returns the IP address
4214 now even if it could not resolve it (but returns also FALSE).
4215 Affected file lib/silcutil/silcnet.[ch].
4217 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Added silc_pkcs_decode_identifier to decode the public key's
4220 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4221 Added also silc_pkcs_free_identifier. Added also new context
4222 SilcPublicKeyIdentifier.
4224 * Added -S option to the silc client. It is used to dump the
4225 contents of the specified public key file.
4227 * Changed the PKCS api to return the public key length when
4228 setting the public key.
4230 * Fixed a fatal bug in the public and private key file loading.
4231 Affected file lib/silccrypt/silcpkcs.c.
4233 * Execute the packet parsing for client with zero (0) timeout
4234 if the protocol is active. Affected file silcd/server.c.
4236 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Made the key generation options to the silcd program. Added
4239 -C option, equivalent to client's option.
4241 * Added new [ServerKeys] config section to the server. It
4242 configures the server's public and private key.
4244 * Defined generic Public Key Payload into the protocol
4245 specification to send specific type of public keys and
4248 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4249 public key or certificate.
4251 * Implemented the GETKEY command to the server and to the
4252 client library and on user interface.
4254 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Made preliminary `make install' work.
4258 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Added SilcServerRekey context into silcd/idlist.h.
4262 * Added the PFS support as defined in the specification to the
4263 SKE protocol. Affected files lib/silcske/*.c.
4265 * Added `ske_group' field to the SilcServerRekey context to hold
4266 the number of the SKE group that is used with PFS in re-key.
4267 Affected file silcd/idlist.h.
4269 * Added PFS re-key support to the server. Affected file is
4272 * Added silc_protocol_cancel to cancel execution of the next
4273 state of the protocol. Affected file is
4274 lib/silccore/silcprotocol.[ch].
4276 * Added the re-key support with and without PFS to the client
4277 library. Re-key is performed once in an hour, by default.
4279 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4280 Added silc_client_rekey_callback and silc_client_rekey_final.
4281 Affected files are lib/silcclient/protocol.[ch] and
4282 lib/silcclient/client.[ch].
4284 * Removed the `hmac_key' and `hmac_key_len' fields from the
4285 SilcClientConnection structure; not needed. Affected file is
4286 lib/silcclient/client.h.
4290 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Do not ask whether user wants to use the negotiated private key
4293 for private messages, just use it. Affected file is
4294 silc/local_command.c.
4296 * Added `send_enc_key' and `enc_key_len' fields to the
4297 SilcIDListData structure since they are needed in the re-key
4298 phase. Affected file is silcd/idlist.[ch].
4300 * Implemented the simple re-key protocol into the server.
4301 Affected files silcd/server.c and silcd/protocol.[ch]. The
4302 re-key will be performed once in an hour, by default.
4304 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4305 Added silc_server_rekey, silc_server_rekey_callback and
4306 silc_server_rekey_final.
4308 * Removed Tunneled flag from the protocol. Updated the code
4309 and the specifications.
4311 * Adde `pfs' field to the SilcIDListData to indicate whether
4312 the PFS is to be performed in the re-key. Affected file is
4315 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4318 int64 of at least the xintXX size. If void * is less that 4
4319 bytes uint32 * will be used. Defined bool as boolean.
4321 * Changed _ALL_ unsigned long and unsigned int to uint32,
4322 unsgined short to uint16 in the source tree.
4324 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4325 not handle clients that has entry->data.registered == FALSE.
4326 They are not in the network anymore. Affected file is
4329 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Implemented the sending of the SERVER_SIGNOFF notify in the
4332 server. Affected file is silcd/server.c.
4334 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4335 Added also silc_notify_payload_encode_args into the
4336 lib/silccore/silcnotify.[ch].
4338 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4339 Affected file silcd/packet_receive.c.
4341 * Implemented the SERVER_SIGNOFF notify handling in the client
4342 library. Affected file lib/silcclient/client_notify.c. Also,
4343 implemnted the printing of the SERVER_SIGNOFF info to the
4344 application. Affected file silc/client_ops.c.
4346 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4347 if the deleting was successful. Affected file silcd/idlist.[ch].
4349 * Added support for public key authentication in the connection
4350 authentication protocol in the client library. Affected file
4351 lib/silcclient/protocol.c.
4353 * Changed the server's silc_idlist_get_clients_by_* interface
4354 to support already allocated array so that new entries may be
4355 added to pre-allocated array. Affected file silcd/idlist.[ch].
4356 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4357 and command replies.
4359 * All command reply functions in the server now calls the
4360 pending command callback even if error occured. This way the
4361 error will be delivered to the client as well. Affected files
4362 silcd/command.c and silcd/command_reply.c.
4364 * Fixed INFO command to return local server's info if no server
4365 was provided. Affected file lib/silcclient/command.c.
4367 * Removed RESTART command for good. Updated the code and the
4370 * Rewrote parts of the task system. It is a bit simpler now.
4371 Removed unsued task priorities. The affected files are
4372 lib/silcutil/silctask.[ch].
4374 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Moved the USERS printing from the library to the application.
4377 Affected files lib/silcclient/command.c and silc/client_ops.c.
4379 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added channel key re-key support. The re-key is perfomed
4384 only by the router and is done once in an hour. Added `rekey'
4385 field to the SilcChannelEntry in the server. Affected files
4386 silcd/server.c and silcd/idlist.h.
4388 * Added silc_task_unregister_by_context into the file
4389 lib/silcutil/silctask.[ch].
4391 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added SILC_UMODE_GONE mode to indicate when the client is not
4394 present in the SILC network. Added also support to the local
4395 command AWAY that will set this mode. Added support of showing
4396 "xxx is gone" in WHOIS command. The USERS command shows the
4397 gone status as well.
4399 * Fixed setting server and router operator privileges in the
4400 server's UMODE command. Affected file silcd/command.c.
4402 * Merged the SKE KE1 and KE2 payloads into one payload. The
4403 new KE payload is equivalent to the old KE2 payload.
4405 Cleaned up the SKE Start Payload parsing. It now uses the
4406 simple buffer unformatting to do the parsing. A lot faster
4409 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4410 to the SKE that is used to indicate whether both of the SKE
4411 parties should perform authentication. By default only the
4412 responder performs authentication. By setting this flag also
4413 the initiator must do authentication. By default it is unset
4414 since in normal SKE case, client to server connection, only
4415 the responder should do authentication. When doing SKE between
4416 two clients both should perform authentication. Updated the
4417 code and the protocol specs.
4419 * A little fix to IDENTIFY command in the server. Search the
4420 client first by hash not nickname. Affected file is
4423 * Fixed the silc_client_close_connection to support closing
4424 the client to client connections wihtout deleting too much
4425 data. Affected file lib/silcclient/client.c.
4427 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4428 are received if protocol used to be active but is not anymore
4429 the application would crash due to NULL pointer dereference.
4430 Affected files silcd/server.c and lib/silcclient/client.c.
4432 * Added `hash' field to the SilcClientConnection to include
4433 the hash function negotiated in the SKE protocol.
4435 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4436 to set the channel founder authentication data. A client can
4437 claim the founder rights later by providing the authentication
4438 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4439 This way the channel founder can regain the channel founder
4440 privileges even it is left the channel. This works only on
4441 local server and the client must be connected to the same
4442 server to be able to regain the founder rights. Updated the
4443 protocol specs accordingly.
4445 Added support to the CMODE command in the client to set the
4446 founder auth data. Read the README to see how to set it.
4448 Added support to the CUMODE command to claim the founder
4449 rights. Read the README to see how to do it.
4451 Added support for the founder authentication to the Channel
4452 Entry in the server. Affected file silcd/idlist.h.
4454 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4455 server's CMODE command. Affected file silcd/command.c.
4457 * Added the following new functions into lib/silccore/silcauth.[ch]:
4458 silc_auth_get_method and silc_auth_get_data.
4460 * The server now saves the remote hosts public key to the
4461 SilcIDListData pointer. Affected file silcd/protocol.c.
4463 * The normal server now does not remove the channel entry from
4464 the cache if the founder authentication data is set. It used
4465 to remove it if the founder was the last one on the channel on
4466 the server and left the channel. The auth data is saved and
4467 if the channel is re-joined later the old entry is used with
4468 the old auth data. Affected files silcd/command_reply.c and
4471 * Removed the `pkcs' field from the SilcIDListData structure
4472 in the server; it is not used. Affected file silcd/idlist.h.
4474 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Fixed packet processing on slow links. Partial packets were
4477 never re-processed because the incoming data buffer was cleared
4478 by the application. Application must not directly clear the
4479 sock->inbuf, the packet processing routines handle it. Fixed
4480 this in client library and in server.
4482 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Fixed the WHOIS and IDENTIFY send reply function to really
4485 check whether to send list or just one entry. Affected file
4488 * Cleaned up the LEAVE command's channel key distribution. The
4489 affected file silcd/command.c.
4491 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4492 can enforce the channel mode as well. In that case the ID
4493 includes the ID of the server. The code now enforces the
4494 mode change if the router have different mode than the server.
4496 * The notify client operation with CMODE_CHANGE notify can now
4497 return NULL client_entry pointer if the CMODE was not changed
4498 by client. Application must check for this.
4500 * Added <Server ID> argument to INFO command to support server
4501 info fetching by Server ID.
4503 * Added silc_server_announce_get_channel_users to get assembled
4504 packets of channel users of the specified channel. Affected
4505 file silcd/server.[ch].
4507 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4508 was freed underneath the ID Cache.
4510 * Re-announce clients when the server received CHANNEL_CHANGE
4511 notify from the router. Affected file silcd/packet_send.c.
4513 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4516 crashed since it did not handle the fact that there is no cipher
4517 called "3" and didn't check the error condition. Now fixed.
4519 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4520 flag. It can be used to send message requests.
4522 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Implemented the RESTART command in the client.
4526 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4527 notice type messages. Added notice printing to the user
4530 * The channel keys are not re-generated if the channel's mode
4531 is PRIVKEY, ie private key on the channel exists. Affected
4532 files silcd/server.c and silcd/command.c.
4534 * Fixed a little bug in channel message delivery when channel
4535 private keys are set in the server. Affected file is
4536 silcd/packet_send.c.
4538 * Changed the setting on channel->on_channel = TRUE from the
4539 silc_client_save_channel_key to the JOIN command reply. The
4540 key payload is not received if the private channel key is set.
4541 Affected file lib/silcclient/command_reply.c and the
4542 lib/silcclient/client_channel.c.
4544 * When the CMODE_CHANGE notify is sent and the channel private
4545 key mode is removed the channel key must be re-generated in
4546 other cells as well. Added this support for the router in the
4547 silcd/packet_receive.c.
4549 * Added new local command NOTICE to send notice message on
4550 channel. Affected file silc/local_command.[ch].
4552 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added new local command ME to the client. It is used to send
4555 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4556 some action. Affected file silc/local_command.[ch].
4558 * Changed channel_message and private_message client operations
4559 to deliver the message flags to the application. Added also
4560 the `flags' arguments to the silc_client_send_channel_message
4561 and silc_client_send_private_message functions. Affected file
4564 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Redefined the Private Message Payload to support private message
4567 keys and to support the new private message flags. Updated
4568 the protocol specs. Flags makes it possible to have for example
4569 CTCP style messages.
4571 * Added new type SilcPrivateMessagePayload and defined an API
4572 for it in the lib/silcclient/silcprivate.[ch].
4574 * Tested private message private keys successfully. Tested the
4575 private message key set, unset and list commands with the new
4578 * Redefined the Channel Message Payload to include the channel
4579 message flags (equal with private message flags) to support
4580 for example CTCP style messages.
4582 * Defined some of the message (for channel and private message)
4583 flags. Updated the protocol specs and added the flags to the
4584 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4586 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added SilcKeyAgreementStatus type to the key agreement routines
4589 to indicate the current status and error if one occured.
4590 The status types are defined in the lib/silcclient/silcapi.h.
4592 * Added new local command KEY that is used to set and unset private
4593 keys for channels, set and unset private keys for private messages
4594 with remote clients and to send key agreement requests and
4595 negotiate the key agreement protocol with remote client. The
4596 key agreement is supported only to negotiate private message keys,
4597 it currently cannot be used to negotiate private keys for channels,
4598 as it is not convenient for that purpose.
4600 * Fixed a minor pending callback setting bug in the function
4601 silc_client_get_client_by_id_resolve, now the function works.
4602 Affected file lib/silcclient/idlist.c.
4604 * Added function silc_net_get_local_port to get local bound
4605 port by socket. Added to lib/silcutil/silcnet.[ch].
4607 * Added `sockets' and `sockets_count' fields to the SilcClient
4608 object. They hold the sockets of the listenning sockets in
4609 the client. Listenning sockets may be for example the key
4610 agreement server. Affected file lib/silcclient/client.[ch].
4611 Added functions the silc_client_add_socket and the
4612 silc_client_del_socket. They are exported to the application
4615 * Added ~./silc/clientkeys to support other client's public keys.
4617 * Renamed verify_server_key client operation to verify_public_key
4618 and added one argument to indicate the type of the connection
4619 (server, client etc.).
4621 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Added silc_server_connection_auth_request to handle the
4624 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4625 silcd/packet_receive.[ch].
4627 * Added silc_server_send_connection_auth_request into the
4628 silcd/packet_send.c to send the connection auth request packet.
4630 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4633 * Fixed the public key authentication in responder side in the
4634 server. The `auth_data' pointer includes the SilcPublicKey
4635 not the path to the public key. Affected file silcd/protocol.c.
4637 * Implemented the public key authentication in the initiator side
4638 in the server. Affected file silcd/protocol.c.
4640 * Removed the [RedirectClient] config section from the server
4641 configuration. Is not needed and I don't want to implement it.
4643 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Cleaned up the CMODE command in the server. It now works
4646 correctly and supports all the modes defined in the protocol.
4647 Affected file is silcd/command.c.
4649 * Added `hmac_name' field to the SilcChannelEntry in the server
4650 to hold the default HMAC of the channel. It can be set when
4651 creating the channel (with JOIN command). Affected files
4654 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4655 type to indicate the change of the current cipher and hmac
4656 on the channel. Client can safely ignore the <cipher> argument
4657 (if it chooses to do so) since the CHANNEL_KEY packet will
4658 force the channel key change anyway. The <hmac> argument is
4659 important since the client is responsible of setting the new
4660 HMAC and the hmac key into use.
4662 * Fixed the CMODE command in the client library as well.
4664 * Tested CMODE command in router environment successfully.
4666 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Show the version of the remote client (or server) when connecting
4669 to the server. It is logged to the log file. Affected file
4670 is silcd/protocol.c.
4672 * Fixed the KILLED notify handling in the client library. The
4673 client must be removed from all channels when receiving the
4676 Also, do not remove the client entry when giving the KILL
4677 command but when the KILLED notify is received.
4679 * Removed silc_idlist_find_client_by_nickname from the server.
4680 Not needed anymore. Affected files silcd/idlist.[ch].
4682 * Implemented the CHANNEL_CHANGE notify type handling to the
4683 server. Affected file silcd/server.c.
4687 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Added silc_server_send_notify_invite to send the INVITE
4690 notify between routers.
4692 * Implemented the INVITE command correctly to the server.
4694 * Implemented the INVITE notify type handling in the server.
4696 * Implemented the INVITE command to the client library and on the
4699 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Added function silc_server_get_client_resolve to find the
4702 client entry by ID from all ID lists and then resolve it
4703 (using WHOIS) if it cannot be found. Affected file is
4706 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Implemented the BAN command to the client library.
4710 * The JOIN command in the server now checks the invite list
4713 * Changed the silc_command_reply_payload_encode_va and the
4714 silc_command_payload_encode_va to support that if argument is
4715 NULL it ignores and checks the next argument. Affected file
4716 lib/silccore/silccommand.c.
4718 * Added silc_server_send_notify_ban to send the BAN notify
4719 type between routers.
4721 * Chaned the silc_notify_payload_encode to support that if
4722 argument is NULL it ignores and checks the next argument.
4723 Affected file lib/silccore/silcnotify.c.
4725 * Tested ban lists in router environment successfully.
4727 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Implemented BAN command to the server, in silcd/command.[ch].
4731 * Removed the BAN and INVITE_LIST modes from the CMODE command
4734 * Added function silc_string_match to regex match two strings.
4735 Affected files lib/silcutil/silcutil.[ch].
4737 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Redefined parts of the SilcChannelEntry in the server to support
4740 the new ban and invite lists.
4742 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Redefined the INVITE command. The same command can be used to
4745 invite individuals to the channel but also to manage the invite
4746 list of the channel (to add to and remove from the invite list).
4747 Updated the protocol specs.
4749 * Added new command SILC_COMMAND_BAN that can be used to manage
4750 the ban list of the channel. Updated the protocol specs.
4752 * Removed the channel modes: the SILC_CMODE_BAN and the
4753 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4754 in the CMODE command. The equivalent features are now available
4755 using INVITE and BAN commands. Updated the protocol specs.
4757 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4758 in the network about change in the current ban list. The notify
4759 type is not used by the client.
4761 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4762 support the invite lists.
4764 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Added new function silc_string_regexify that converts string
4767 including wildcard characters into regex string that can
4768 be used by the GNU regex library. Added into the file
4769 lib/silcutil/silcutil.[ch].
4771 Added silc_string_regex_combine to combine to regex strings
4772 into one so that they can be used as one regex string by
4773 the GNU regex library. Added into the file
4774 lib/silcutil/silcutil.[ch].
4776 Added silc_string_regex_match to match two strings. It returns
4777 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4779 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Imported GNU regex to the soruce tree into lib/contrib.
4782 Fixed some compiler warning from the regex.c.
4784 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Fixed MOTD command in the server to work in router environment.
4788 * Fixed the MOTD command in the client library to support
4789 the server argument in the command.
4791 * Added `nickname_len' argument to the silc_idlist_add_client
4792 in the server, as the `nickname' argument may be binary data
4795 * Added silc_idlist_get_channels to return all channels from
4798 * Implemented LIST command to the server. Affected file is
4801 * Implemented the LIST command to the client library and on the
4804 * Added [<user count>] argument to the LIST command reply.
4805 With private channels the user count is not shown.
4807 * Updated TODO and README.
4809 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * The client entry's data.registered must be TRUE even with
4812 global client entry on global client list. The data.registered
4813 is used to check whether the client is anymore in the network,
4814 for example with WHOWAS command so it must be valid.
4816 * Fixed the WHOWAS command in the server. It now actually works
4817 in router environment. Added function into silcd/command_reply.c
4818 silc_server_command_reply_whowas_save.
4820 * Added silc_idlist_purge function to the silcd/idlist.c
4821 to periodically purge the ID Cache.
4823 * Fixed INFO command in the server. It works now in router
4824 environment. Added <server name> argument to the INFO command
4825 reply. Updated the protocol specs.
4827 * Fixed minor bug in silc_idcache_purge to not purge if the
4828 expire value is zero.
4830 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4831 they were buggy because of the WHOWAS information.
4833 * Fixed local command MSG to handle the async resolving of
4834 the remote client properly. It used to fail the first MSG.
4835 Affected file silc/local_command.c.
4837 * Added `data_len' field to SilcIDCache context.
4839 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Update TODO. Todo in commands in the server.
4843 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4846 used by routers as broadcast packet to inform other routers
4847 about the changed user mode.
4849 Implemented the notify handling in the server. Affected file is
4850 silcd/packet_receive.c. Added the function
4851 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4853 * Added new generic Channel Payload and deprecated the New Channel
4854 Payload. The New Channel Payload is now the generic Channel
4857 * Added new argument `mode' to the silc_server_send_new_channel
4858 as it is required in the Channel Payload now.
4860 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4861 and created a new and real SilChannelPayload to represent the
4862 new generic Channel Payload. Implemented the encode/decode
4863 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4865 * Added silc_server_get_client_channel_list to return the list
4866 of channels the client has joined for WHOIS command reply.
4867 Affected file silcd/server.[ch].
4869 * Implemented the channel list sending in the WHOIS command reply
4870 in server and in the client.
4872 Implemented the channel list displaying on the user interface
4873 as well. Affected file silc/client_ops.c.
4875 * Added silc_channel_payload_parse_list to parse list of Channel
4876 Payloads. It returns SilcDList list of SilcChannelPayloads.
4877 Client for example can use this function to parse the list of
4878 channels it receives in the WHOIS command reply. The caller
4879 must free the list by calling silc_channel_payload_list_free.
4880 Affected files lib/silccore/silcchannel.[ch].
4882 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added one new argument <user mode> to the WHOIS command reply
4885 to return the mode of the user in SILC. Updated the protocol
4888 Implemented it to the server and client.
4890 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Fixed the mode printing on the user interface on joining.
4893 Affected file silc/client_ops.c.
4895 * Implemented the UMODE command and user modes in general to the
4896 client library and to the user interface.
4898 * Implemented the UMODE command to the server.
4900 * The server now sends UNKNOWN_COMMAND error status if client sends
4901 unknown command. Affected file silcd/command.c.
4903 * All server commands now handle the command identifier the right
4904 way when sending the command reply to the client. The client can
4905 use to identify the command replies with the identifier.
4907 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added silc_server_get_client_route to resolve the route to
4910 the client indicated by the client ID. Affected file is
4913 * Added silc_server_relay_packet as general function to relay
4914 packet to arbitrary destination. This deprecates functions
4915 like _send_private_message_key, _relay_notify etc. Affected
4916 file is silcd/packet_send.[ch].
4918 Removed silc_server_send_key_agreement,
4919 silc_server_send_private_message_key and
4920 silc_server_packet_relay_notify functions from the file
4921 silcd/packet_send.[ch].
4925 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4926 server. Affected file silcd/packet_receive.[ch].
4928 * Implemented the KILL command to the client. Implemented the
4929 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4930 Affected files lib/silcclient/command[_reply].c and
4931 lib/silcclient/client_notify.c. Implemented the KILL notify
4932 printing in the user inteface.
4934 * Fixed a lot silc_parse_nick memory leaks from the client
4935 library in the file lib/silcclient/command.c.
4937 * Changed the silc_server_send_notify_on_channels's `sender'
4938 argument from SilcSocketConnection to SilcClientEntry to
4939 check the sender as entry and not as connection object and not
4940 to send to the client provided as argument. The affected file
4941 is silcd/packet_send.[ch].
4943 * The notify packets that are destined directly to the client used
4944 to not to be processed by the server. Now changed that and the
4945 server processes all notify packets. After relaying the packet
4946 to the client the notify packet is processed in the server.
4948 * The silc_server_free_client_data now checks whether there is
4949 pending outgoing traffic for the client and purges the data to
4950 the network before removing the client entry.
4952 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4955 an client is killed from the SILC Network. Updated the protocol
4958 Added new function silc_server_send_notify_killed to the
4959 silcd/packet_send.[ch].
4961 * Added function silc_server_packet_relay_notify to relay notify
4962 packets that are destined directly to a client. In this case
4963 the server does not process the notify packets but merely relays
4964 it to the client. Affected file silcd/packet_send.[ch].
4966 Added also silc_server_packet_process_relay_notify to check
4967 whereto relay the notify. Affected file is
4968 silcd/packet_receive.[ch].
4970 * Implemented the KILL command to the server.
4974 * Added the backup schema desgined last fall to the protocol
4975 specs for everyone to see. The specification is in the
4976 *-spec-xx.txt draft and the packet type definitions for the
4977 backup routers is in *-pp-xx.txt draft. Thusly, added also
4978 new packet type SILC_PACKET_CELL_ROUTERS.
4980 * A big security problem in the implementation discovered. The
4981 signoff of an client did not cause new channel key generation
4982 which it of course should've done. The channel keys must be
4983 always re-generated when client leaves (or signoffs) the channel.
4984 The silc_server_remove_from_channels funtion now handles
4985 the channel key re-generation.
4987 * Added `sender' argument to the silc_server_send_notify_on_channels
4988 to not to send the client provided as argument. Affected file
4989 silcd/packet_send.[ch].
4991 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Implemented OPER and SILCOPER commands into the server and
4996 * Added silc_auth_verify and silc_auth_verify_data to verify
4997 the authentication directly from the authentication payload.
4998 It supports verifying both passphrase and public key based
4999 authentication. Affected file lib/silccore/silcauth.[ch].
5001 * Added `hash' field to the SilcIDListData structure. It is the
5002 hash negotiated in the SKE protocol. Affected file is
5005 * Slight redesigning of the SilcAuthPayload handling routines.
5006 Do not send SilcPKCS but SilcPublicKey as argument.
5008 * Implemented the public key authentication support to the
5009 serverconfig. The public key is loaded from the provided path
5010 and saved as authentication data to void * pointer. Thus,
5011 changed the unsigned char *auth_data to void *auth_data;
5013 * Fixed SHUTDOWN command to send the reply before the server
5014 is shutdown. :) Affected file silcd/command.c.
5016 * Fixed fatal bug in CONNECT command. The hostname was invalid
5017 memory and server crashed. Affected file silcd/command.c.
5019 * Fixed fatal bug in CLOSE command. The server_entry became
5020 invalid but was referenced later in the command. Affected file
5023 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Fixed fatal bug in failure packet handling. Server ignored
5026 the failure and thus crashed when it came.
5030 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5033 that the command may be executed only once in (about) 2 seconds.
5034 The old SILC_CF_LAG flag is same but allows command bursts up
5035 to five before limiting.
5037 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5038 server code. Various commands now includes the CF_LAG_STRICT
5039 flag to disallow any kind of miss-use of the command.
5041 * Fixed the silc_buffer_unformat to not to allocate any data
5042 if the length of the data is zero. It used to allocate the
5043 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5045 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Changed the format of AdminConnection configuration section
5048 in the server. Added username of the admin to the format.
5049 Affected files silcd/serverconfig.[ch].
5051 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5052 to return admin configuration data by host, username and/or
5055 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Implemented WHOWAS command to the server. Added the functions:
5059 silc_server_command_whowas_parse,
5060 silc_server_command_whowas_send_reply,
5061 silc_server_command_whowas_from_client and
5062 silc_server_command_whowas_from_server
5064 * Added <Client ID> argument to the WHOWAS command reply. Updated
5065 the protocol specs accordingly.
5067 * Implemented WHOWAS command and command_reply to the client
5070 Implemented the WHOWAS printing on the user interface.
5072 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Added new argument to the WHOWAS command reply, the real name.
5075 It is an optional argument. Updated the protocol specs.
5077 * Added SilcIDCacheDestructor callback that is registered when
5078 the SilcIDCache is allocated. The callback is called when
5079 an cache entry in the ID Cache expires, or is purged from the
5080 cache. Added into lib/silccore/idcache.[ch].
5082 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5083 to destruct the client entries when the cache entry expires.
5084 Other ID Cache's in server and in the client library ignores
5087 * If the ID Cache entry's `expire' field is zero then the entry
5088 never expires. Added boolean `expire' argument to the
5089 silc_idcache_add function in the lib/silccore/idcache.[ch].
5090 If it is TRUE the default expiry value is used.
5092 * Added silc_server_free_client_data_timeout that is registered
5093 when client disconnects. By default for 5 minutes we preserve
5094 the client entry for history - for WHOWAS command.
5096 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Added support to the server to enforce that commands are not
5099 executed more than once in 2 seconds. If server receives
5100 commands from client more frequently, timeout is registered
5101 to process the commands. Affected file silcd/command.c.
5102 Added new function silc_server_command_process_timeout.
5104 * Changed NICK_NOTIFY handling in client library to check that
5105 if the client's nickname was changed, so there is no need to
5106 resolve anything from the server.
5108 * Removed error printing from the WHOIS and IDENTIFY commands.
5109 If error occurs then it is ignored silently in the client library.
5110 The application, however, may map the received error to
5111 human readable error string. The application currently maps
5112 the NO_SUCH_NICKNAME error to string.
5114 * Made the command status message public to the application. Moved
5115 them from lib/silcclient/command_reply.c to
5116 lib/silcclient/command_reply.h. The application can map the
5117 received command status to the string with the
5118 silc_client_command_status_message function.
5120 * Added check to the server to check that client's ID is same
5121 as the Source ID in the packet the client sent. They must
5124 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Added dist-bzip hook to the Makefile.am to make bzip2
5127 compressed distributions.
5129 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Server now enforces the maximum length for the nickname and
5132 the channel as protocol specification dictates. 128 bytes for
5133 nickname and 256 bytes for channel name.
5135 * Moved the WHOIS printing to the application. The client libary
5136 does not print out the WHOIS information anymore, the application
5137 must do it. Renamed silc_client_command_reply_whois_print to
5138 the silc_client_command_reply_whois_save.
5140 The client's idle time is also sent to the application now, and
5141 the idle is shown on screen.
5143 * Added silc_client_command_reply_identify_save to save the
5144 received IDENTIFY entries.
5146 * Do not check for channel private keys in message sending and
5147 reception if the channel does not have the PRIVKEY mode set.
5148 Affected file lib/silclient/client_channel.c.
5150 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5153 just surfaced after chaning the JOIN procedure.
5155 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added silc_client_get_clients_by_list to get client entries
5158 from Client ID list, that is returned for example by JOIN
5159 and USERS command replies. The application should use this
5160 function for example when JOIN command reply is received to
5161 resolve the clients already on the channel (library does not
5162 do that anymore as USERS command reply is not used in the JOIN
5163 procedure anymore). Affected files lib/silcclient/silcapi.h and
5164 lib/silcclient/idlist.c.
5166 * JOIN command reply and USERS command reply returns now SilcBuffer
5167 pointers instead of unsigned char pointers when returning
5168 the client list and mode list.
5170 * Added <Client ID> argument to the JOIN command reply, mainly
5171 for the server to identify for which client the command was
5172 originally sent. Updated protocol specs accordingly.
5174 * Added SilcDlist private_key pointer to the SilcChannelEntry
5175 in the client to support the channel private keys. Affected
5176 file is lib/silcclient/idlist.h.
5178 * Added SilcChannelPrivateKey argument to the function
5179 silc_client_send_channel_message so that application can choose
5180 to use specific private ke if it wants to. If it is not provided,
5181 the normal channel key is used, unless private keys are set.
5182 In this case the first (key that was added first) is used
5183 as the encryption key.
5185 * Implemented the support for channel private key handling.
5186 Implemented the following functions:
5188 silc_client_add_channel_private_key,
5189 silc_client_del_channel_private_keys,
5190 silc_client_del_channel_private_key,
5191 silc_client_list_channel_private_keys and
5192 silc_client_free_channel_private_keys
5194 Affected file lib/silcclient/client_channel.c.
5196 * Added the support for the private keys in the channel message
5197 sending and encryption and in the message reception and
5198 decryption. Affected funtions are
5199 silc_client_send_channel_message and silc_client_channel_message.
5201 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Added SKE's key verify callback to the client library's
5204 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5206 * Removed the statement that server (or router) must send USERS
5207 command reply when joining to the channel so that the client
5208 knows who are on the channel. Instead, the client list and
5209 client's mode list is now sent in the JOIN command reply to the
5210 client who joined channel. This is better solution.
5212 * Added function silc_server_get_users_on_channel and function
5213 silc_server_save_users_on_channel to the silcd/server.[ch].
5215 * Removed function silc_server_command_send_users from the
5218 * Do not show topic on the client library anymore. The topic is
5219 sent in the command reply notify to the application and the
5220 application must show the topic now.
5222 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Added client searching by nickname hash into the IDENTIFY and
5225 WHOIS commands in the server as they were clearly missing from
5226 them. Affected file is silcd/command.c.
5228 * Fixed a bug in private message receiving in the client library.
5229 The remote ID was freed and it wasn't supposed, now it is
5232 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Minor fix to the channel payload; allocate the data area, as it
5235 needs to be of specific length.
5237 * If the key agreement port is zero then the operating
5238 system will define the bound port. Affected files are
5239 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5241 * Added new function silc_channel_payload_decrypt into the file
5242 lib/silccore/silcchannel.[ch].
5244 * Moved the channel message etc, check from silc_packet_decrypt
5245 to applications. The library calls now a generic
5246 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5247 when the packet is either normal or special. This was done to
5248 allow more wide range of checking that was not allowed when
5249 the code was in library. Now applications can do virtually any
5250 checks to the packet and return to the library the decision how
5251 the packet should be processed. Affected files are
5252 lib/silccore/silcpacket.[ch].
5254 Added silc_server_packet_decrypt_check to the server and
5255 silc_client_packet_decrypt_check to the client library.
5257 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5258 to send with specified source and destination information.
5260 * Channel message delivery between routers was broken after the
5261 channel key distribution was fixed earlier. The channel key
5262 was used be to distributed to other routers as well which is not
5263 allowed by the protocol. Now this is fixed and channel keys
5264 really are cell specific and the channel message delivery between
5265 routers comply with the protocol specification.
5267 * Fixed various commands in server to check also the global list
5268 for the channel entry and not just the local list. The affected
5269 file silcd/command.c.
5271 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Added assert()s to buffer formatting and unformatting routines
5274 to assert (if --enable-debug) when error occurs. Affected
5275 file: lib/silcutil/silcbuffmt.c.
5277 * Changed to auto-reconnect to check whether the remote host is
5278 router and register the re-connect timeout if it is. It used
5279 to check that whether we are normal server, but router must do
5280 auto-reconnect with another router as well. Affected file
5283 * Removed the [<key len>] option from CMODE command as the cipher
5284 name decides the key length, nowadays. See the defined ciphers
5285 from the protocol specification.
5287 * Added [<hmac>] option to the CMODE command to define the HMAC
5288 for the channel. Added SILC_CMODE_HMAC channel mode.
5290 * Added [<hmac>] option for the JOIN command so that user can
5291 select which HMAC is used to compute the MACs of the channel
5294 * Added Hmac field to the Channel Message Payload. The integrity
5295 of plaintext channel messages are now protected by computing
5296 MAC of the message and attaching the MAC to the payload. The
5297 MAC is encrypted. Now, it is clear that this causes some
5298 overhead to the size of the packet but rationale for this is that
5299 now the receiver can verify whether the channel message decrypted
5300 correctly and also when private keys are set for the channel the
5301 receiver can decrypt the packet with several keys and check from
5302 the MAC which key decrypted the message correctly.
5304 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5305 lib/silccrypt/silccipher.[ch].
5307 * Added silc_hash_len to return the digest length into the
5308 lib/silcrypt/silchash.[ch].
5310 * Rewrote parts of Silc Channel Payload interface in the
5311 lib/silccore/silcchannel.[ch]. The encode function now also
5312 encrypts the packet and parse function decrypts it.
5314 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Fixed a minor formatting bug in the SKE's key material processing.
5317 It actually might have processed the keys wrong way resulting
5320 * Redefined the mandatory HMAC algorithms and added new algorithms.
5321 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5322 and hmac-md5 truncated to 96 bits. The mandatory is now
5323 hmac-sha1-96. Rest are optional (including the one that used
5324 to be mandatory). Rationale for this is that the truncated HMAC
5325 length is sufficient from security point of view and can actually
5326 make the attack against the HMAC harder. Also, the truncated
5327 HMAC causes less overhead to the packets. See the RFC2104 for
5330 * Added new [hmac] configuration section. The SKE used to use
5331 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5332 is of course wrong. The official names that must be proposed in
5333 the SKE are the ones defined in the protocol specification
5334 (hmac-sha1-96 for example). The user can configure any hmac
5335 using any hash function configured in the [hash] section. At
5336 least, the mandatory must be configured.
5338 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5340 * Added HMAC list to the SKE proposal list. It has now both
5341 hash algorithm list and HMAC list. This makes the protocol
5342 incompatible with previous versions. The SKE now seems to work
5343 the way it is supposed to work, for the first time actually.
5345 * Defined plain Hash algorithms to the protocol specification.
5348 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Implemented support for key agreement packets into the server.
5351 Added functions silc_server_key_agreement and
5352 silc_server_send_key_agreement. Other than these functions,
5353 server has nothing to do with this packet.
5355 * Added support for private message key packets into the server.
5356 Added functions silc_server_private_message_key and
5357 silc_server_send_private_message_key.
5361 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5362 called in the protocol's final callback instead in the END
5363 protocol state. This makes a little more sense and in the same
5364 time in client we can use the same protocol routines for normal
5365 key exchange and to key agreement packet handling as well.
5367 * Added to both client's and server's KE protocol context the
5368 SilcSKEKeyMaterial pointer to save the key material. We will
5369 bring the key material to the protocol's final callback by doing
5370 this. The final callback must free the key material.
5372 * Added SKE's packet_send callback into client's KE protocol
5373 context so that the caller can choose what packet sending function
5374 is used. This way we can use different packet sending when
5375 doing normal SKE when doing key agreement packet handling (in
5376 the key agreement packet handling we do not want to encrypt
5379 * Implemented the responder side of the key agreement routines
5380 in the client. The client can now bind to specified port and
5381 accept incoming key negotiation. The key material is passed
5382 to the application after the protocol is over.
5384 * Implemented the processing of incoming Key Agreement packet
5385 in the client. Added function silc_client_key_agreement to
5388 * Implemented the intiator side of the key agreement routines
5389 in the client. The client can now initiate key agreement with
5390 another remote client. The key material is passed to the
5391 application after the protocol is over.
5393 * Created client_keyagr.c to include all the key agreement
5396 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5397 SILC_TASK_CALLBACK except that it is not static.
5399 * Created client_notify.c and moved the Notify packet handling
5400 from the client.[ch] into that file.
5402 * Created client_prvmsg.c and moved all private message and
5403 private message key routines from the client.[ch] into that file.
5405 * Create client_channel.c and moved all channel message and
5406 channel private key routines from the client.[ch] into that file.
5408 * Changed silc_client_get_client_by_id_resolve to resolve with
5409 WHOIS command instead of IDENTIFY command, in the file
5410 lib/silclient/idlist.c.
5412 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Implemented the SKE's responder side to the Client library.
5416 * When FAILURE is received to the protocol do not trust it
5417 blindly. Register a timeout to wait whether the remote closes
5418 the connection as it should do it, only after that process the
5419 actual failure. This was changed to both client and server.
5421 * Added client_internal.h to include some of the structures
5422 there instead of client.h in lib/silcclient/.
5424 * Added function silc_task_unregister_by_callback to unregister
5425 timeouts by the callback function.
5427 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Some "Incomplete WHOIS info" errors has been appearing on the
5430 log files. Took away the entry->userinfo check from WHOIS
5431 reply sending. The entry->userinfo is now " " if client did not
5432 provide one. I thought this was fixed earlier but something
5433 is wrong still. Let's see if the error still appears.
5435 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Fixed a minor bug in the login when the channel key is
5438 re-generated in the server. It used to generate the key in
5439 wrong order and thus caused problems in the channel traffic.
5441 * Fixed a minor bug in channel key distsribution after
5442 KICK command. The key was not sent to the router even though
5445 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added silc_ske_process_key_material_data as generic routine
5448 to process any key material as the SILC protocol dictates. The
5449 function is used by the actual SKE library but can be used by
5450 applications as well. This relates to the private message keys
5451 and the channel private keys since they must be processed the
5452 same way the normal SILC session keys. The protocol dictates
5453 this. Affected files: lib/silcske/silcske.[ch].
5455 Added also silc_ske_free_key_material to free the
5456 SilcSKEKeyMaterial structure.
5458 * Defined silc_cipher_set_key function to set the key for
5459 cipher without using the object's method function. The affected
5460 files: lib/silccrypt/silccipher.[ch].
5462 * Implemented silc silc_client_add_private_message_key,
5463 silc_client_add_private_message_key_ske,
5464 silc_client_del_private_message_key,
5465 silc_client_list_private_message_keys and
5466 silc_client_free_private_message_keys functions in the
5469 Added functions silc_client_send_private_message_key to send
5470 the Private Message Key payload and silc_client_private_message_key
5471 to handle incoming Private Message Key payload.
5473 * Added Cipher field to the Private Message Key payload to set
5474 the cipher to be used. If ignored, the default cipher defined
5475 in the SILC protocol (aes-256-cbc) is used.
5477 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Removed lib/silcclient/ops.h file.
5481 Redefined parts of the SILC Client Library API. Created new
5482 file silcapi.h that deprecates the ops.h file and defines the
5483 published Client Library API. Defined also private message key
5484 API and channel private key API into the file.
5486 This is the file that the application must include from the
5487 SILC Client Library. Other files need not be included by
5488 the application anymore.
5490 * Added new key_agreement client operation callback and also
5491 defined the Key Agreement library API for the application.
5493 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5496 is used by clients to request key negotiation between another
5497 client in the SILC network. If the negotiation is started it
5498 is performed using the SKE protocol. The result of the
5499 negotiation, the secret key material, can be used for example
5500 as private message key.
5502 Implemented the Key Agreement payload into the files
5503 lib/silccore/silauth.[ch].
5505 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Redefined ciphers for the SILC protocol. Added some new ciphers
5508 and defined the key lengths for the algorithms. Changed the
5509 code accordingly. The default key length is now 256 bits.
5511 * Fixed SKE key distribution function silc_ske_process_key_material
5512 when the key length is more than 128 bits. The default key
5513 length in SILC is now 256 bits.
5515 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5516 to indicate unsupported algorithm.
5518 * Renamed rijndael.c to aes.c and all functions as well.
5520 * Fixed a long standing channel key setting bug in client library.
5521 Weird that it has never surfaced before.
5523 * Fixed bug in channel deletion. If the entire channel is removed
5524 then it must also delete the references of the channel entry
5525 from the client's channel list as the client's channel entry and
5526 the channel's client entry share same memory.
5528 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Implemented CONNECT and SHUTDOWN commands in the client.
5532 * Implemented CLOSE command to the client.
5534 * Added the function silc_idlist_find_server_by_name into the
5535 files silcd/idlist.[ch].
5537 Added the function silc_idlist_find_server_by_conn into the
5538 files silcd/idlist.[ch].
5540 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * DIE command was renamed to SHUTDOWN. Updated the both code
5545 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5546 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5548 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5551 * Added function silc_server_create_connection function to create
5552 connection to remote router. My server implementation actually
5553 does not allow router to connect to normal server (it expects
5554 that normal server always initiates the connection to the router)
5555 so the CONNECT command is only good for connecting to another
5558 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5561 or some other client was kicked from the channel.
5563 Implemented the handling of the notify type to both client
5566 Implemented silc_server_send_notify_kicked to send the KICKED
5567 notify. It is used to send it to the server's primary router.
5569 * Implemented the KICK command into server and client.
5571 * Added `query' argument to the silc_idlist_get_client function
5572 to indicate whether to query the client from server or not if
5575 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5576 to indicate that the client is not channel founder.
5580 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Removed the rng context from SilcPacketContext structure and
5583 changed that the packet routine uses the Global RNG API.
5585 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Added support for quit message that client can "leave" on the
5588 channel when it quits the SILC. It is ditributed inside the
5589 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5591 Added silc_server_free_client_data that will take the
5592 signoff message as argument.
5594 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5596 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Updated parts of the protocol specification to keep it up
5601 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5604 payloads in one packet.
5606 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5607 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5608 use now the new List flag.
5610 * Also deprecated the following packet types: REPLACE_ID,
5611 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5613 * Added list support for Notify packet in server.
5615 * Added silc_server_send_notify_channel_change to send the
5616 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5617 the silc_server_send_replace_id.
5619 * Added silc_server_send_notify_nick_change to send the
5620 NICK_CHANGE notify type. Deprecates the function
5621 silc_server_send_replace_id.
5623 * Added silc_server_send_notify_join to send the JOIN notify type.
5624 Deprecates the function silc_server_send_new_channel_user.
5626 * Added silc_server_send_notify_leave to send LEAVE notify type.
5627 Deprecates the function silc_server_send_remove_channel_user.
5629 * Added silc_server_send_notify_cmode and
5630 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5631 types. Deprecates the silc_server_send_set_mode function.
5633 * Added SERVER_SIGNOFF notify type to indicate that server has
5634 quit. This means that all clients on the channel from that
5635 server will drop. This can be also used when netsplit happens.
5637 Deprecated REMOVE_ID packet type since it is not needed anymore
5640 Added silc_server_send_notify_server_signoff to send the
5641 SERVER_SIGNOFF notify type. Deprecates the function
5642 silc_server_send_remove_id.
5644 Added also silc_server_send_notify_signoff to send the
5645 SIGNOFF notify type.
5647 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5648 SILC protocol from this day on. Changed the protocol
5649 specification as well.
5651 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5652 notify type. It is used between routers to notify about
5653 topic changes on a channel.
5655 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5658 * Partly updated the protocol specification to comply with the
5659 changes now made. It is still though a bit outdated.
5661 * The JOIN notify type now takes one extra argument <Channel ID>.
5662 The packet used to be destined to the channel but now the
5663 JOIN type may be sent as list thus it is impossible to
5664 destine it to any specific channel. By adding this argument
5665 it is again possible.
5667 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added CREDITS file. The CHANGES and CREDITS file will appear
5670 in the distribution as well.
5672 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5675 types in the server's silcd/packet_receive.c.
5677 * Implemented CMODE and CUMODE to work in router environment.
5679 * Fixed minor encoding and decoding buglet from the
5680 lib/silccore/silcmode.c.
5682 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5685 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5687 * Changed all SilcConfigServer* and silc_config_server* to
5688 SilcServerConfig* and silc_server_config*, respectively.
5691 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Associated the ID (client or server ID) to the Authentication
5694 Payload to avoid any possibility of forging. Updated the
5695 protocol specification and the code accordingly.
5697 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * The RSA key length is now save to the RsaKey context in the
5700 key generation process in lib/silccrypt/rsa.c. The key length
5701 is now used to figure out the maximum size of the block allowed
5702 to be encrypted/signed.
5704 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5705 is equivalent to the silc_mp_mp2bin but does not allocate any
5708 * Changed silc_mp_mp2bin API to take length argument. If it is
5709 non-zero then the buffer is allocated that large. If zero, then
5710 the size is approximated using silc_mp_sizeinbase, which however
5713 * Created Global RNG API which is global RNG that application can
5714 initialize. After initializing, any routine anywhere in the
5715 code (including library) can use RNG without allocating a new
5716 RNG object. This was done to allow this sort of use of the
5717 RNG in code that has no chance to allocate RNG object. All
5718 applications currently allocate this and many routines in the
5719 library use this. Affected file lib/silccrypt/silcrng.[ch].
5721 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5722 it to use the Global RNG API.
5724 * Defined Authentication Payload into protocol specification that
5725 is used during SILC session to authenticate entities. It is
5726 used for example by client to authenticate itself to the server
5727 to obtain server operator privileges.
5729 Implemented this payload into the lib/silccore/silcauth.[ch].
5730 Implemented also routines for public key based authentication
5731 as the new protocol specification dictates.
5733 Moved definitions of different authentication methods from
5734 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5736 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5737 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5738 silc_pkcs_verify_with_hash functions into the file
5739 lib/silccrypt/silcpkcs.[ch].
5741 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * The client entry's userinfo pointer must be always valid.
5744 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5745 will fail since it requires the userinfo. Now, the userinfo
5746 is allocated as "" if actual userinfo does not exist. Actually,
5747 it must exist and it is totally Ok to drop client connections
5748 that does not announce the userinfo. However, we will make
5749 this workaround for now.
5751 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5752 to return the remote port by socket.
5754 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5757 SILC_SERVER_PENDING_EXEC and added an new macro
5758 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5759 data or when error occurs while processing the pending command.
5761 Added new argument `destructor' into silc_server_command_pending
5762 and to the SilcServerCommandPending object. This destructor is
5763 now called after calling the pending callback or if error occurs
5764 immediately. If error occurs the actual pending callback won't
5765 be called at all - only the destructor. The destructor may be
5766 NULL if destructor is not needed.
5768 All this applies for client library code as well. Similar
5769 changes were made there as well for the pending commands.
5771 In the client, the application must now allocate the
5772 SilcClientCommandContext with the silc_client_command_alloc
5775 * Added reference counter to the SilcServerCommandContext. Added
5776 function silc_server_command_alloc and silc_server_command_dup
5779 Same type of functions added to the client library for the same
5782 * Removed the cmd_ident from IDListData away since it is now
5783 global for all connections. It is the command identifier used
5784 in command sending and with pending commands. The affected file
5787 * Added reference counter to the SilcSocketConnection objecet to
5788 indicate the usage count of the object. The object won't be
5789 freed untill the reference counter hits zero. Currently only
5790 server uses this, and client ignores it. The client must be
5791 set to use this too later. The affected files are
5792 lib/silccore/silcsockconn.[ch]. Added also the function
5793 silc_socket_dup to increase the reference counter.
5795 This was mainly added because it is possible that the socket
5796 is removed underneath of pending command or other async
5797 operation. Now it won't be free'd and proper DISCONNECTING
5798 flags, etc. can be set to avoid sending data to connection that
5799 is not valid anymore.
5801 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5802 the connection. After that it sets SILC_SET_DISCONNECTED.
5803 It is, however, possible that the socket data is not still freed.
5804 The silc_server_packet_process now checks that data is not
5805 read or written to connection that is DISCONNECTED. The socket
5806 get's freed when the reference counter hits zero.
5808 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Changed the client operation API: channel_message operation's
5811 `sender' is now the client entry of the sender, not the nickname
5812 and the `channel' is the channel entry, not the channel name.
5814 In the private_message operation the `sender' is now also the
5815 client entry of the sender not the nickname.
5817 Affected file is lib/silcclient/ops.h and all applications
5818 using the client operations.
5820 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Moved the calling of ops->connect() from connect_to_server_final
5823 into receive_new_id functin since that is the point when the
5824 client is actually allowed to send traffic to network. The
5825 affected file is lib/silcclient/client.c.
5827 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5830 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5831 (if needs broadcasting) instead of broadcasting the packets one
5832 by one which would make a burst in the network traffic.
5834 * Added `broadcast' argument to the functions in silcd/server.[ch]
5835 silc_server_create_new_channel[_with_id] to indicate whether
5836 to send New Channel packet to primary router.
5838 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added new function into the silcd/server.[ch] files:
5841 silc_server_create_new_channel_with_id to create new channel with
5842 already existing Channel ID.
5844 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5845 lib/silccore/silcpacket.h. This packet is used t send list of
5846 Set Mode payloads inside one packet. Server uses this to set
5847 the modes for the channels and clients on those channels, that it
5848 announced to the router when it connected to it. The protocol
5849 specification has been updated accordingly.
5851 * The silc_server_new_channel did not handle the packet coming
5852 from normal server as it normally does not send that. However,
5853 when it announces its channels it does send it. Implemented
5854 the support for that.
5856 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5857 into the file lib/silccore/id.h.
5859 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Fixed memory leaks in the functions silc_idlist_del_client,
5862 silc_idlist_del_channel and silc_idlist_del_server in the file
5863 silcd/idlist.c. All of those leaked like a sieve.
5865 * Fixed some small memory leaks in the client's function
5866 silc_client_notify_by_server.
5868 * Added functions into silcd/server.c: silc_server_announce_clients,
5869 silc_server_announce_channels and silc_server_announce_server.
5870 These functions are used by normal and router server to announce
5871 to its primary router about clients, channels and servers (when
5872 router) that we own. This is done after we've connected to the
5875 These functions effectively implements the following packet types:
5876 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5877 and SILC_PACKET_NEW_ID_LIST.
5879 * Added new functions into the silcd/packet_receive.[ch]:
5880 silc_server_new_id_list, silc_server_new_channel_list and
5881 silc_server_new_channel_user_list to handle the incoming
5882 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5884 * Added support of changing Channel ID in the function
5885 silc_server_replace_id. If the server that announces a channel
5886 to the router already exists in the router (with same name but
5887 with different Channel ID), router is responsible to send
5888 Replace ID packet to the server and force the server to change
5889 the Channel ID to the one router has.
5891 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5892 client that the Channel ID has been changed by the router. The
5893 normal server sends this to the client. Client must start using
5894 the new Channel ID as the channel's ID.
5896 Implemented handling of this new type into lib/silcclient/client.c
5897 into the function silc_client_notify_by_server.
5899 * Added new function silc_idlist_replace_channel_id into the files
5900 silcd/idlist.[ch] to replace the Channel ID.
5902 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Call silc_server_command_identify_check always when processing
5905 the IDENTIFY command in silcd/command.c
5907 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5910 send keepalive packets. The packet can be sent by clients,
5911 servers and routers.
5913 Added function silc_socket_set_heartbeat into the file
5914 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5915 If not set, the heartbeat is not performed. The actual
5916 heartbeat is implemented in the low level socket connection
5917 library. However, application is responsible of actually
5920 Added silc_server_send_heartbeat to send the actual heartbeat
5921 packet into silcd/packet_send.[ch]. Server now performs
5922 keepalive with all connections.
5924 * Added silc_task_get_first function into lib/silcutil/silctask.c
5925 to return the timeout task with shortest timeout. There was a bug
5926 in task unregistration that caused problems. TODO has been
5927 updated to include that task system must be rewritten.
5929 * The client library will now resolve the client information when
5930 receiving JOIN notify from server for client that we know but
5931 have incomplete information.
5933 * Rewrote parts of silc_server_remove_from_channels and
5934 silc_server_remove_from_one_channel as they did not remove the
5935 channel in some circumstances even though they should've.
5937 * Encryption problem encountered in server:
5939 The LEAVE command used to send the Channel Key packet to the
5940 router immediately after generating it. However, the code
5941 had earlier sent Remove Channel user packet but not immediately,
5942 ie. it was put to queue. The order of packets in the router
5943 was that Channel Key packet was first and Remove Channel User
5944 packet was second, even though they were encrypted in the
5945 reverse order. For this reason, MAC check failed. Now, this
5946 is fixed by not sending the Channel Key packet immediately but
5947 putting it to queue. However, this is more fundamental problem:
5948 packets that are in queue should actually not be encrypted
5949 because packets that are sent immediately gets encrypted
5950 actually with wrong IV (and thus MAC check fails). So, packets
5951 that are in queue should be encrypted when they are sent to
5952 the wire and not when they put to the queue.
5954 However, the problem is that the current system has not been
5955 designed to work that way. Instead, the packet is encrypted
5956 as soon as possible and left to the queue. The queue is then
5957 just purged into wire. There won't be any fixes for this
5958 any time soon. So, the current semantic for packet sending
5961 o If you send packet to remote host and do not force the send
5962 (the packet will be in queue) then all subsequent packets to the
5963 same remote host must also be put to the queue. Only after the
5964 queue has been purged is it safe again to force the packet
5967 o If you send all packets immediately then it safe to send
5968 any of subsequent packets through the queue, however, after
5969 the first packet is put to queue then any subsequent packets
5970 must also be put to the queue.
5972 Follow these rules and everything works fine.
5974 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added new function silc_server_remove_clients_by_server to
5977 remove all client entries from ID list when the server connection
5978 is lost. In this case it is also important to invalidate all
5979 client entires as they hold the invalid server entry. This
5980 fixes fatal bug when server has lost connection and will reconnect
5983 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Made some sanity checks to silc_server_daemonise like to check
5986 whether the requested user and group actually exists.
5988 * Added sanity check to SKE's silc_ske_responder_finish to check
5989 that the public and private key actually is valid.
5991 * Invalidate the client's nickname when receiving Replace ID
5992 packet and the Client ID is being replaced. This means that the
5993 server will query the nickname if someone needs it (client)
5996 * Sort the ID Cache in client library when the ID Cache data
5997 has changed (needs sorting).
5999 * Do not allow for SILC client to create several connections to
6000 several servers. The client does not support windows right now
6001 and generating multiple connections causes weird behaviour.
6003 Irssi-silc client does support windows and can handle several
6004 connections without problems, see: www.irssi.org and SILC plugin.
6006 * Fixed some places where client was added to the IDList. The
6007 rule of thumb is following (in order to get everything right):
6008 If the client is directly connected local client then the
6009 `connection' argument must be set and `router' argument must be
6010 NULL to silc_idlist_add_client function. If the client is not
6011 directly connected client then the `router' argument must
6012 bet set and the `connection' argument must be NULL to the
6013 silc_idlist_add_client function.
6015 * The funtion silc_server_packet_send_local_channel actually did
6016 not check whether the client was locally connected or not. It
6017 does that now. Fixed a bug related to LEAVE command.
6019 * Fixed Remove Channel User payload parsing bug in server's
6020 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6022 * The server's silc_server_save_channel_key now checks also the
6023 global ID list for the channel as it might not be in the local
6024 list. Fixed a bug related to LEAVE command.
6026 * Is this the end of the [<unknown>] buglet that has been lurking
6027 around for a long time? A little for loop fix in server's
6028 silc_server_command_whois_parse that is used by both IDENTIFY
6029 and WHOIS command. At least, this was a clear bug and a cause
6030 of one type of [<unknown>] buglet.
6032 * WHOIS and IDENTIFY commands call the function
6033 silc_server_command_[whois/identify]_check function even if
6034 we are not router server.
6036 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added --with-gmp configuration option. If set the GMP
6039 is always compiled in the SILC source tree. If not set then
6040 it is checked whether the system has the GMP3 installed. If
6041 it has then the GMP won't be compiled (the system's headers
6042 and library is used), if it doesn't have it then the GMP is
6043 compiled in the SILC source tree.
6045 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Changed RSA private exponent generation to what PKCS #1
6048 suggests. We try to find the smallest possible d by doing
6049 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6050 not security fix but optimization.
6052 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Added new config entry [Identity] to fork the server and run
6055 it as specific user and group. A patch from Bostik.
6057 * Imported Dotconf configuration library into lib/dotconf.
6058 This will be used to create the SILC configuration files later.
6059 It will appear in the distsribution after this commit.
6061 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * A big code auditing weekend happening. Auditing code for
6064 obvious mistakes, bugs and errors. Also, removing any code
6067 Removed files for being obsolete:
6069 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6070 inline in the file lib/silcutil/silcbuffer.h)
6072 o lib/silcutil/silcbufutil.c (the header has inline versions)
6074 Changed code to fix possible error conditions:
6076 o The buffer formatting routines now check that the destination
6077 buffer really has enough space to add the data. This applies for
6078 both buffer formatting and unformatting
6079 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6080 unformatting was changed to accomodate following rules:
6081 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6082 sent to the function while XXX_*STRING will not allocate or copy
6083 the data into the buffer. Instead it sets the pointer from the
6084 buffer into the pointer sent as argument (XXX_*STRING used to
6085 require that the pointer must be allocated already). This change
6086 makes this whole thing a bit more consistent and more optimized
6087 (note that the data returned in the unformatting with XXX_*STRING
6088 must not be freed now). The routines return now -1 on error.
6090 o Tried to find all code that use buffer_format and buffer_unformat
6091 and added return value checking to prevent formatting and
6092 especially unformatting errors and possible subsequent fatal
6095 o Changed ske->x and ske->KEY to mallocated pointers in
6096 lib/silcske/silcske.h. Fixed possible data and memory leak.
6098 o Added return value checking to all *_parse* functions. Fixed
6099 many memory leaks as well.
6101 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6102 so that buffer overflows would not happen. All code now also
6103 checks the return value as it can fail.
6105 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added reconnection support to server if the normal server looses
6108 its connection to the router (for example if router is rebooted).
6109 The server performs normal reconnection strategy implemented
6110 to the server. Affected file silcd/server.c.
6112 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added new packet type SILC_PACKET_SET_MODE that is used to
6115 distribute the information about changed modes (for clients,
6116 channels and clients channel modes) to all routers in the
6117 network. Updated the protocol specification accordingly.
6119 Added functions into silcd/packet_send.c and
6120 silcd/packet_receive.c: silc_server_send_set_mode,
6121 silc_server_set_mode.
6123 Added new files silcmode.[ch] into lib/silccore that implements
6124 the encoding and decoding of Set Mode Payload. Added new type
6125 SilcSetModePayload. Moved the definitions of different modes
6126 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6128 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Oops, a little mistake in server's connection authentication
6131 protocol. The protocol is not ended with FAILURE but with
6132 SUCCESS if the authentication is Ok. :) Affected file is
6135 * Implemented NICK_CHANGE notify handling in server in the file
6136 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6137 the local clients on the channel. After the changing nickname
6138 in router environment snhould work and the [<unknown>] nickname
6139 should appear no more.
6141 The silc_server_replace_id function that receives the Replace ID
6142 payload now sends the NICK_CHANGE notify type also in the file
6143 silcd/packet_receive.c
6145 * Changed WHOIS and IDENTIFY command to support the maximum amount
6146 of arguments defined in protocol specs (3328 arguments). This
6147 fixed a bug that caused problems when there were more than three
6150 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added extra parameter, command identifier, to the
6153 silc_client_send_command so that explicit command identifier
6156 Changed that ID list routines uses specific command identifier
6157 when sending WHOIS/IDENTIFY requests to the server so that they
6158 can be identified when the reply comes back.
6160 Affected files lib/silcclient/command.[ch],
6161 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6163 * Added `sender' argument to silc_server_packet_send_to_channel
6164 to indicaet the sender who originally sent the packet to us
6165 that we are now re-sending. Ignored if NULL. Affected file
6166 silcd/packet_send.[ch].
6168 * Added some server statistics support in silcd/server_internal.h
6169 SilcServerStatistics structure and around the server code. Also
6170 send some nice statistics information when client is connecting
6173 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Fixed channel ID decoding in server's JOIN command reply in
6176 silcd/command_reply.c
6178 * Fixed braodcasting of replace ID payload to not to send it if
6179 we are standalone server in silcd/packet_receive.c.
6181 * Fixed all channel message sending routines to not to send
6182 packets to clients that has router set, since they are routed
6183 separately in the same function earlier. Affects file
6184 silcd/packet_send.c and all channel packet sending functions.
6186 * In USERS reply, res_argv[i] are not allocated, the table
6187 is allocated. Thus changed that free the table, not its
6190 * In server's whois_check and identify_check if the client is
6191 locally connected do not send any WHOIS commands - they are not
6194 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Fixed some minor bugs in client when sending WHOIS command. The
6197 arguments was in wrong order.
6199 * Removed statis function add_to_channel from server in
6200 silcd/command.c that was previously used with the joining but
6203 * Tested USERS command in router environment successfully with two
6204 routers, two servers and two clients.
6206 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Reorganized the USERS command and command reply in client library
6209 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6210 When the command is given by user we register a pending command
6211 callback that will reprocess the command after the reply has been
6212 received from the server. When reprocessing the packet we then
6213 display the information. Thus, the USERS information is displayed
6214 now in the command callback instead of in the command reply
6215 callback. The processing of the command is same as previously
6216 when server has sent the command reply in the JOINing process.
6218 * Added to USERS command in silcd/command_reply.c to join the client,
6219 we didn't use to know about, to the channel after we've created
6220 a client entry for it. Also, for clienet we did know already still
6221 check whether it is on the channel or not and add it if not.
6223 * Removed silc_server_command_join_notify as the function and its
6226 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Changed the client's pending command handling to the same as the
6229 server's pending command handling. It is also now possible to
6230 execute command reply functions from other command reply
6231 function as the function callbacks for commands and command
6232 replies are one and same. The pending commands are not static
6233 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6234 in client connection context. Thus, pending commands are server
6235 connection specific as it is convenient.
6237 Changed the function silc_client_command_pending and
6238 silc_client_command_pending_del and added new function
6239 silc_client_command_pending_check. Removed the
6240 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6243 * Added cmd_ident, current command identifier, to the client
6244 connection context in lib/silcclient/client.h to keep track on
6245 command identifiers used in command sending. Client's command reply
6246 function handling now supports the mandatory command identifiers.
6248 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6249 funtions in client to fully support pending command callbacks.
6251 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6252 as one of the arguments to the application in the command reply
6255 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6256 before first releasing SILC but came back. Now it is removed again
6257 and should come back nomore. The FORWARDED flag was used only
6258 by the JOINing procedure by forwarding the command packet to router.
6259 Now, the JOINing procedure has been changed to more generic (due
6260 to various router environment issues) and FORWARDED is not needed
6261 anymore for anything. The protocol specification is yet to be
6264 Now, removed silc_server_packet_forward from server and the flag
6265 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6267 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Renamed NAMES command to USERS command. The NAMES was named that
6270 due to historical reasons. Now it is renamed. Also, rewrote
6271 parts of the USERS command. The nickname list is not sent anymore
6272 by the server. Only Client ID and mode lists are sent in the USERS
6273 command. Changed this also to the protocol specification.
6275 The client now resolves the names and stuff after it receives
6276 the USERS list from the server when joining to the channel.
6278 * WHOIS and IDENTIFY commands has been changed to support multiple
6279 Client ID's per command. One can now search for multiple users
6280 in the network by sending only one WHOIS or IDENTIFY command.
6281 Changed the code and the protocol specifications.
6283 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6284 uses silc_server_command_whois_parse to parse the request. */
6286 * If normal server, do not parse the WHOIS and IDENTIFY requests
6287 before sending it to the router. Saves some time.
6289 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Fixed JOIN command on client library. Wrong number of arguments
6292 used to crash the client.
6294 * Added silc_server_channel_has_global function to check whether
6295 channel has global users or not.
6297 * Added silc_server_channel_has_local function to check whether channel
6298 has locally connected clients on the channel.
6300 * The silc_server_remove_from_one_channel now checks whether the
6301 channel has global users or not after given client was removed from
6302 the channel. It also checks whether the channel has local clients
6303 on the channel anymore. If it does not have then the channel entry
6304 is removed as it is not needed anymore.
6306 * The silc_server_notify now checks on JOIN notify whether the joining
6307 client is one of locally connected or global. If it is global then
6308 the channel has now global users on the channel and that is marked
6309 to the channel entry. Also, it now saves the global client to
6310 global list who is joining and JOINs it to the channel. This is
6311 for normal server, that is.
6313 Changed silc_server_send_notify_on_channel,
6314 silc_server_packet_relay_to_channel and
6315 silc_server_packet_send_to_channel check if we are normal server
6316 and client has router set (ie. global client) do not send the
6317 message to that client, as it is already routed to our router.
6319 * Implemented LEAVE notify type handling in silc_server_notify
6322 * Tested LEAVE command in router environment successfully. Tested
6323 with two routers, two servers and two clients.
6327 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6329 * Implemented SIGNOFF notify type handling in silc_server_notify
6332 * silc_server_remove_id now removes the client entry from all channels
6333 it has joined and thusly sends SIGNOFF notify type.
6335 * Rewrote the NAMES list generation in server by removing two excess
6336 loops. The lists are created now inside one loop.
6338 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * silc_server_remove_channel_user checks now also global list
6341 for channel and client.
6343 * silc_server_new_channel_user checks now both local and global
6344 list for channel and client. Fixed a bug in client id decoding.
6345 Used to decode wrong buffer.
6347 * silc_server_channel_message checks now both local and global
6348 list for channel entry.
6350 * Tested channel joining (hence JOIN) in router environment
6351 successfully. Tested with two routers, two servers and two
6354 * Tested channel message sending in router environment successfully.
6356 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Added silc_server_save_channel_key into server.[ch] to save the
6359 received channel key in Channel Key payload processing. It is
6360 also used in JOIN command reply handling.
6362 Equivalent function silc_client_save_channel_key added into
6363 client.[ch] into client library.
6365 * Changed JOIN command reply to send information whether the channel
6366 was created or not (is existing already) and the channel key
6367 payload. Changed protocol specs accordingly.
6369 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6370 the request was sent by ID and not by nickname. Crashed on
6373 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6376 now correctly save the received data.
6378 * silc_server_free_sock_user_data now notifies routers in the
6379 network about entities leaving the network.
6381 At the same time implemented functions silc_server_remove_id
6382 and silc_server_send_remove_id to receive and send REMOVE_ID
6383 packets. The packet is used to notify routers in the network
6384 about leaving entities. The ID removed will become invalid in
6387 * Added function silc_idlist_del_server into server. Removes and
6388 free's server entry from ID list.
6390 * silc_server_private_message function now checks, if we are router,
6391 that the destination ID really is valid ID, naturally.
6393 * In router when NEW_ID packet is received (for new client) the
6394 hash of the Client ID is saved in the ID Cache but the
6395 client->nickname is set to NULL, instead of putting the hash
6398 IDENTIFY command now also checks that client->nickname must be
6399 valid. If it is not if will request the data from the server who
6400 owns the client. Added new function
6401 silc_server_command_identify_check.
6403 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6404 to set the command to already allocated Command Payload.
6406 * Tested private message sending in router environment with two
6407 routers, two servers and two clients. Fixed minor bugs and now
6410 * Fixed segfault from client's NAMES command. Used to crash if
6413 * Forwarded packets must not be routed even if it is not destined
6414 to the receiver. Changed server code comply with this.
6416 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Added `require_reverse_mapping' boolean value to ServerParams
6419 structure. If TRUE (not default) the server will require that
6420 the connecting host has fully qualified domain name.
6422 If the reverse mapping is not required and hostname could not be
6423 found the IP address is used as hostname.
6425 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6427 * Implemented version string checking to both client and server.
6428 The check is incomplete currently due to the abnormal version
6429 strings used in development version of SILC.
6431 * Changed all command functions in server to use the new
6434 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Changed char *data to unsigned char *data in ID Cache system to
6437 support binary data as ID Cache data. Changed code to support
6438 binary data in lib/silccore/idcache.c.
6440 * Renamed silc_server_packet_relay_command_reply to
6441 silc_server_command_reply as it is normal packet receiving
6442 function. Rewrote the function to accept command replys for
6443 servers and not only for clients.
6445 * Mark remote router always as registered server if we are connecting
6446 to it. Otherwise, commands sent by the router to us are ignored.
6448 * All ID List find routines now returns the ID Cache Entry pointer
6449 as well if requested.
6451 * WHOIS command works now in router environment, tested with two
6452 routers, two servers and two clients.
6454 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6455 in router environment (as it is almost equivalent to WHOIS) but
6456 hasn't been tested thoroughly. Added new functions:
6458 silc_server_command_identify_parse
6459 silc_server_command_identify_send_reply
6460 silc_server_command_identify_from_client
6461 silc_server_command_identify_from_server
6463 * Disabled route cache adding because adding two different ID's with
6464 same IP replaces the old cache entry thus giving wrong route.
6465 The entry->router->connection is always the fastest route anyway
6466 so route cache may not be needed. Of course, new routes maybe
6467 established after receiving the ID when the entry->router->connection
6468 might not be anymore the most optimal.
6470 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Add route cache for received ID for fast routing.
6474 * Added silc_server_packet_route to route received packet on router
6475 that is not destined to us.
6477 * Renamed silc_server_get_route to silc_server_route_get.
6479 * Added id_string and id_string_len fields into SilcServer to
6480 include encoded ServerID for fast comparing without excess
6481 encoding of the ID's.
6483 * Cleaned up WHOIS command on server side. Added following static
6486 silc_server_command_whois_parse
6487 silc_server_command_whois_check
6488 silc_server_command_whois_send_reply
6489 silc_server_command_whois_from_client
6490 silc_server_command_whois_from_server
6492 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6493 arguments in command replies. All command functions should be
6494 updated to use this macro.
6496 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Minor typo fixes on command reply handling on server.
6500 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added silc_server_command_add_to_channel internal routine to add
6503 the client to the channel after router has created the channel and
6504 sent command reply to the server.
6506 * Added generic silc_server_send_command to send any command from
6509 * Use static buffer with ID rendering instead of duplicating data.
6511 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Fixed a channel user mode bug when joining to a channel server gave
6514 everybody channel founder rights, oops.
6516 * We mark ourselves as the router of the incoming server connection
6517 if we are router ourselves. This way we can check in some packet
6518 sending functions whether it is locally connected server. For
6519 incoming router connections we put NULL.
6521 * For router sending packets locally means now always sending the
6522 packet cell wide; to local clients and local servers. For normal
6523 server sending packet locally means sending it to only local
6526 * Fixed the JOIN command to really work in router environment. If the
6527 channel is created it is always created by the router. Router is
6528 also responsible of making the initial joining to the channel,
6529 sending JOIN notify to the sending server and distributing
6530 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6531 does not exist server doesn't do anything else but forward the
6532 command to the router which performs everything.
6534 * Added silc_server_send_channel_key function to send the Channel Key
6537 * Added silc_server_create_channel_key to create new channel key. The
6538 channel key is now re-generated everytime someone joins or leaves
6539 a channel, as protocol dictates. Note: channel->key_len is the
6542 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6545 packet_receive.[ch] to separate packet sending and receiving
6546 routines. The server.[ch] now includes everything else including
6547 actual packet processing (writing and reading data) and other
6550 Renamed silc_server_private_message_send_internal to
6551 silc_server_send_private_message. The routine is still though
6552 used only to relay private messages as server does not send
6553 private messages itself.
6555 Renamed silc_server_new_channel to silc_server_create_new_channel
6556 and added new function sicl_server_new_channel that handles the
6557 incoming New Channel packet. Added also new sending function
6558 silc_server_send_new_channel to send New Channel Payload.
6560 * Added new function silc_server_notify to process incoming notify
6561 packet to the server/router. Server may then relay the notify
6562 to clients if needed.
6564 * Added new function silc_server_new_channel_user to process incoming
6565 New Channel User packet. Router will redistribute the packet and
6566 send JOIN notify to its local clients and locally connected servers
6567 if needed. Normal server will send JOIN notify to its local client
6568 on same channel when received this packet. Added also corresponding
6569 sending function silc_server_send_new_channel_user to sent the
6572 * Added boolean route argument to send_notif_to_channel and
6573 packet_send_to_channel functions to attempt to route the packet
6574 if it is TRUE and send only locally if it is FALSE.
6576 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * silc_server_replace_id now broadcasts the received replace ID
6579 packet if it is not broadcast packet already. The router must
6580 broadcast to inform other routers about changed ID.
6582 * Added backpointer to server's router into SilcServer context in
6583 silcd/server_internal.h.
6585 * Fixed silc_server_packet_broadcast to send correct broadcast
6588 * The channel key is now distributed to the local client as soon
6589 as it is received from the router (in router environment) so that
6590 no other packet may be sent for the channel until client has
6593 * silc_server_remove_channel_user now broadcasts the received
6594 Remove Channel User packet if it is not broadcast packet already.
6595 The router must broadcast to inform other routers about removed
6598 * Added users field into SilcPacketContext that is a reference count
6599 of the context. One can increase the reference count by calling
6600 silc_packet_context_dup which is now changed to just increase the
6601 reference count instead of duplicating the data. The reference
6602 count is decresed by calling silc_packet_context_free that will
6603 free the data after the reference count hits zero.
6605 For now on the packet context and everything allocated into it
6606 (including the raw packet from network) must be freed by calling
6607 the new silc_packet_context_free function. Added also new function
6608 silc_packet_context_alloc that must be used now to allocate the
6609 context. This also means that if a routine is asynchronous from
6610 silc_[client/server]_packet_parse_type the packet context must
6611 be duplicated by calling silc_packet_context_dup. Otherwise it
6612 gets free'd after silc_[client/server]_packet_parse_type returns.
6613 Also, one must remember that if packet is duplicated then its
6614 reference count must be decresed by calling the free function as
6615 many times as it was duplicated.
6617 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6618 from both client and server.
6620 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Made joining to a channel working in router environment.
6624 * Cleaned up JOIN command on server side and create function
6625 silc_server_command_join_channel internal routine to make the
6628 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Changed silc_command_pending list to SilcDList. Also, added
6631 `ident' field to SilcServerCommandPending structure to identify
6632 the reply and to call correct callback.
6634 Added silc_server_command_pending_check function to replace the
6635 corresnponding macro. The silc_command_pending list is not
6638 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6639 to set identifier to previously allocated Command Payload. It
6640 is used to set identifier for command when resending Command
6643 * Added silc_command_payload_encode_payload to encode Command
6644 Payload buffer from SilcCommandPayload structure.
6646 * Added silc_argument_payload_encode_payload to encode Argument
6647 payload buffer from SilcArgumentPayload structure.
6649 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Changed WHOIS command to support router connection on server side.
6652 The whois request is always sent to router unless the server is
6653 standalone server. After server has received the reply from the
6654 router will it send the reply to the client.
6656 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6657 broadcast received broadcast packet. The function is used only
6658 by router. The broadcast packet is always sent to the router's
6661 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6662 render given ID to printable string, for log files for example.
6664 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Made basic router to router connections working. At least they
6667 can now connect to each other but nothing really works the way
6668 they are supposed - yet.
6670 * Added new initiator token to RouterConnection configuration
6671 file in silcd/serverconfig.[ch]. It is used to tell whether we
6672 are the initiator to the remote router or whether we'll expect
6673 the other end to connect.
6675 * Moved registering of listener task to silc_server_init, hence
6676 the server starts listenning as soon as it is run, even if it
6677 does not have connections to other routers. Let's see how well
6680 * Changed default connection retry timeouts for more suitable in
6683 * Removed cipher and such arguments from silc_idlist_add_client
6684 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6685 Added new function silc_idlist_add_data to add the keys and stuff
6688 * Added SilcIDListData structure and added it to SilcClientEntry
6689 and SilcServerEntry as their first field in the structure. This
6690 way we can explicitly cast the ID entries to the SilcIDListData
6691 structure and get common data for the entries. In past, we had
6692 to first check what type of connection it is and then cast it to
6693 correct ID entry type. Now, we can directly cast the opaque
6694 pointer to the SilcIDListData (no matter what ID entry it actually
6695 is) and get the data needed.
6697 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6700 in some circumstances even if threre were timeout tasks, though not
6701 IO tasks, but tasks anyway. Now fixed.
6703 * Defined SilcServerConnection structure to hold connection specific
6704 stuff about directly connected servers and routers. The definition
6705 is currently in silcd/server_internal.h. I thought about having
6706 a bit more important role fro this struct but for now it is used
6707 only when connecting to other server (or router actually).
6709 * Added connecting retry support in server when connecting to
6710 router(s). The retry feature implement exponential backoff
6711 algorithm. Also, added SilcServerParams structure to hold default
6712 parameters for server. For now, it include these retry settings
6713 and are hard coded. After server is moded to be as Silc Server
6714 Library this structure will be more important.
6716 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Changed client librarys channel->clients table to SilcList and
6719 changed code accordingly.
6721 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Changed client's channel table to SilcList and changed code
6724 accordingly. Also changed SilcChannelClientEntry to include back-
6725 pointer to the channel so that client entry can use that structure
6726 as list as well and we have fast cross-reference to the channel.
6727 This change dramatically decreased the complexity of channel
6728 handling with client entry and vice versa (removed one extra
6729 loop when searching for channel entry from many functions).
6731 * Changed server->sim from table to SilcDList and changed code
6734 * NAMES command can now be used from user interface. It will show
6735 the user list on the channel, neatly.
6737 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6738 Code now saves realname of the user if it becomes available.
6740 * Renamed configure.in to configure.in.pre and made ./prepare
6741 script to automatically add correct version string to
6742 configure.in which it creates from configure.in.pre.
6744 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * NAMES command reply now shows users mode with the nickname when
6749 * Moved silc_client_ch[u]mode[_char] functions from
6750 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6751 place sucks, they are utility functions and should be in some
6754 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6756 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6759 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Added TRQ (efficient deque and list library) into lib/trq. This is
6764 a very good list library that is currently used in the SILC. Defined
6765 SilcList API over the library because I didn't like the API very
6766 much. See lib/trq/silclist.h for the API and examples of how to
6767 use the API. Fixed various places in the code to use the new
6768 SilcList API. The SilcList is meant for lists that has a structure
6769 already defined as a list. It is not suitable to add just some
6770 context to the list (in TRQ, the context is the list actually).
6772 So, I defined SilcDList that can be used for the purpose where
6773 predefined list structure does not exit. This can be used as
6774 such list. Now some context just can be added to the SilcDList.
6775 Currently this list is not used in the SILC just yet, though there
6776 are a lot places where this can replace dynamically allocated
6777 tables and I will fix these places, later, to use SilcDList.
6778 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6779 and use TRQ internally).
6781 Also fixed some annoying warning messages that the original TRQ
6782 code generated. Also minor changes to TRQ's Makefile.in.
6784 * Added support for querying by Client ID to both WHOIS and
6785 IDENTIFY commands into server, as required by the protocol.
6787 * Removed method function pointers from SilcBuffer structure. They
6788 weren't used to anything and just increased the context size for
6789 no good reason. This change also made silc_buffer_alloc and
6790 silc_buffer_free functions inline functions.
6792 * Disabled command flooding detection support until it's fixed so
6793 that it accepts commands in but does not execute them more than once
6796 * Added silc_net_localhost(), to return local hostname, into
6797 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6798 that must be initialized before calling silc_client_init.
6800 * Added new function: silc_server_send_notify_on_channels to send
6801 notify messages to all channels client has joined. It is assured
6802 that the message is sent only once per client.
6804 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6805 lib/silcutil/silcutil.[ch] as silc_format function. The new
6806 function is generic and is used by server as well, not only by
6807 the logging routines.
6809 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6810 the provided version string was not acceptable. Added new function:
6811 silc_ske_check_version into lib/silcske/silcske.h. The function
6812 must be implemented by the application (client or server) and it
6813 does not reside in the SKE library. The function checks the version
6814 string remote end sent.
6816 * Added back pointers (to opaque context and to SilcSocketConnection)
6817 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6819 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6820 duplicate packet context structure.
6822 * Changed `notify' client operation to send same arguments as client
6823 receives from server except for ID's. ID's are mapped to correct
6824 ID entry and that is returned. Also, if channel entry is not sent
6825 by server but the notify is for channel the channel entry is sent
6826 to application (otherwise application doesn't know that it is for
6827 channel (library gets it from packet's Destination ID)).
6829 * Added silc_client_remove_from_channels into client library to
6830 remove a client from all channels it has joined to. Used when
6831 received SIGNOFF notify from server. Added also new function
6832 silc_client_replace_from_channels to replace old ID entry with
6833 new ID entry on all channels. Used when received NICK_CHANGE
6836 * Fixed ID Cache list handling in silc_idlist_get_client in
6837 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6838 to get (or query) client by ID.
6840 * Updated TODO list.
6842 * Added connection authentication status message defined by the
6843 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6844 support for these into the code in client and server side.
6846 * Added generic function silc_client_send_command to send any command
6847 with variable argument list. Application should use this function
6848 to send commands if the command functions provided by the library
6849 does not suite for the application's user interface needs.
6851 * Added new `failure' client operation. Application is notified about
6852 received failure packet if client is executing a protocol. In this
6853 case the protocol's execution has failed.
6855 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6856 is required by the protocol.
6858 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6859 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6862 * Added status flag to SilcSKE object to indicate realtime status
6863 of the SKE protocol.
6865 * Application receives now exactly same command reply arguments as
6866 the library receives from server. However, if ID is received the
6867 corresponding ID entry is returned to the application (eg. Client
6868 ID is mapped to correct SilcClientEntry entry and that is returned).
6869 Changed command_reply client operation due to this change.
6871 * Changed all ID's in commands and in command replys as ID Payloads.
6872 Change affected both client and server side codes.
6874 All ID's sent in SILC network (with execption of ID's in SILC
6875 Packet header) are sent in ID Payload to support variable length
6878 * Server now notifies nick changes and notifies all clients on
6879 the channels about the new nickname (about the new Client ID,
6882 * Implemented CMODE command to change channel modes. Supports all
6883 channel modes defined by the protocol specs except ban and invite
6884 lists. (Also, private channel key mode is supported but support for
6885 setting private channel key in client is missing, thus, this mode
6886 has no effect on client side (except that server requires that the
6887 client uses private channel key and normal channel traffic does not
6890 Also, invite mode works per se, but INVITE command does not work
6891 yet correctly, so you can set channel as invite only channel but
6892 inviting clients to the channel does not work (it is yet to be
6893 thought what's the best way to do it).
6895 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6896 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6897 Implemented CUMODE command to change user's mode on the channel.
6898 Supports all modes defined by the protocol specs.
6900 * Added NAMES command reply to return users modes on the channel.
6902 * Removed unnecessary and slow ciphers from lib/silccrypt.
6904 * Set SO_KEEPALIVE option to connection sockets by default.
6906 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6908 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6909 redefined the Notify Payload into protocol specs.
6911 * Added silc_id_payload_parse_id to get ID directly from raw
6914 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6917 accept searching by Client ID as well.
6919 * Added support for LEAVE and SIGNOFF notify types in client library.
6921 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6922 to parse ID Payload from raw data.
6924 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added flags parameter into silc_ske_assemble_security_properties
6927 function in lib/silcske/silcske.[ch].
6929 * Changed notify client operation to fit better for notify messages
6930 sent by server. The notify payload received from server is now
6931 passed to the application (after parsing it to SilcNotifyPayload).
6932 It is application's responsibility to retrieve the arguments
6933 from the payload and show the message the way it wants. The message
6934 sent by server is implementation specific.
6936 * Changed public keys to comply with the protocol specification.
6937 Old public keys are not supported anymore and are not compatible.
6939 * Removed nickname from Channel Payload as the latest draft removed
6940 it. The client must resolve the nickname from the NAMES command
6941 reply received when it joined the channel.
6943 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6945 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Fixed some errors in protocol specification drafts.
6949 * Created lib/silccore/silcnotify.c to implement Notify Payload
6950 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6951 generic payloads described by protocol specifications. The file
6952 includes implementations for ID Payload and Argument Payload.
6954 * Changed Command Payload implementation to use the new Argument
6955 Payload. Changed command_xxxx_payload to command_payload_xxxx
6956 to comply with SILC coding conventions.
6958 * Added suppport for Argument Payload handling in Notify Payload
6959 implementation as protocol requires it. Added the new support
6960 into server and client lib as well.
6962 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Added support for multiple nicknames on same channel. [n] is
6965 added locally to the nickname if there are more than one same
6966 nicknames on the channel.
6968 * Server now sends all nicknames that matched WHOIS request.
6969 Client also shows the list received from server.
6971 * Added TOPIC command to client side. User can now set and show
6972 current topic on channel.
6974 * Added MOTD command to client and server. Also, server sends the
6975 motd when client connects to the server.
6977 * Changed version strings to comply ISO 8601.
6979 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Fixed protocol error handling in client library. It should now
6982 cope even if the SKE fails for some reason.
6984 * Made new protocol specification drafts for submitting to IETF.
6986 * Implemented TOPIC command to server in silcd/command.c.
6988 * Added two new notify types into lib/silccore/silcnotify.h:
6989 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6990 notify nickname change and topic setting/change on a channel.
6992 * API change of command_reply operation in client library. The
6993 application gets now the status type received from server as well.
6995 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6997 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6999 * Cras fixed and optimized the packet handling even further and
7000 it should work now. Minor change to the prototype of function
7001 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7003 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Added new function into lib/silcutil/silcschedule.[ch]:
7006 silc_schedule_with_fd to select() a specified fd. The function
7007 returns after timeout expires or data arrives or goes. The
7008 function is used by packet routines to wait that all data is
7009 received from network.
7011 * Fixed data reading from network in lib/silccore/silcpacket.c.
7012 The code now assures that all data is read from the fd and then
7013 continues packet processing. This was a bug fix since the code
7014 used to drop some data in some circumstances.
7016 * Added new function into lib/silcclient/client.[ch]:
7017 silc_client_start_key_exchange to start key exchange after
7018 connection has been established to server. The code internally
7019 now uses this funtion but its main purpose was to provide it
7020 for applications that perform their own connecting. After
7021 application has created a connection it merely calls this
7022 function to start the key exchange between client and server.
7023 The library takes care of everything else after that.
7025 Updated also lib/silcclient/README to explain the usage of
7028 * Do not send to application information that connection has
7029 been established. Application gets notified it by connect
7032 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Applied cras's patch to add silc_schedule_one function. The
7035 function runs scheduler once and returns.
7037 * Fixed the scheduler after cras messed it up. The timeout
7038 handling works now as it's supposed to work.
7040 * Added into lib/silccore/ silcnotify.h to include notify
7041 message types support. Changed silc_server_send_notify*
7042 functions, in server.[ch], to support those new notify types.
7043 Added the support for the notify types into client library,
7044 as well. Added new notify client operation into ops.h in
7047 * Changed silc_server_packet_send_to_channel to send normal
7048 packets instead of just channel message packets. The function
7049 is now used to send the notify packets to channels. It is not
7050 used to send channel message packets anymore, as server never
7053 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7054 va_arg()s as it seems to require it nowadays. I guess, if SILC
7055 is compiled with older va_arg() the new code should work anyway.
7057 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * Splitted core library. Core library (lib/silccore) includes
7060 now only SILC protocol specific core (and common) components.
7061 Created new utility library (lib/silcutil) that includes more
7062 generic purpose stuff. The stuff for util library was taken
7063 from the old core library. This was minor and easy split.
7065 * Created SILC Client Library (lib/silcclient) that includes
7066 implementation of the SILC client without user interface. This
7067 was major move from silc/ directory. The code has been changed
7068 so that it is transparent towards the user interface. The
7069 silc/ directory includes now the same user interface as before
7070 and it uses the new client library. Read lib/silcclient/README.
7071 Basicly, the client library performs everything else related
7072 to SILC except user interface handling. Also, configuration
7073 files are considered to be part of user interface and library
7074 does not handle them.
7076 This change also changed a lot of structures, function naming etc.
7077 Most important change was that SilcClientWindow object was
7078 renamed to SilcClientConnection in the client library. Created
7079 also new file lib/silcclient/ops.h. Also added new files
7080 silc/local_command.[ch] and silc/client_ops.[ch].
7082 All these changes were made to make it easier for user interface
7083 designers to create what ever user interface for the SILC client
7086 It is also expected that the server will be moved to lib
7087 directory as well and SILC Server Library will be created;
7088 sometimes in the future.
7090 * Removed Local commands from lib/silccore/silccommand.h as
7091 they are application specific and new client library does not
7092 handle any of those anymore.
7094 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7095 old client implementation in silc/.
7097 * Added support for callback functions in SILC_LOG_* macros.
7098 Application can now set its own callbacks that will be called
7099 instead of using the default functions that will always print
7100 the debug messages to stderr (or stdout). Also, debugging can
7101 now be disabled by setting silc_debug to FALSE and re-enabled by
7102 setting it to TRUE. Note, that logging will still work even
7103 if debugging is disabled.
7105 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7106 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7107 silc_log_reset_debug_callbacks.
7109 * To enable debugging in silc client one must give now -d
7110 option on command line.
7112 * Changed silc_schedule_init to automatically allocate task queues
7113 if they are not allocated before calling it.
7115 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * Added GMP 3.1 into math library.
7119 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7122 a channel in SILC network. The packet is used by servers and
7123 routers to notify other routers that user has left a channel.
7124 This little feature was missing until now. Added the feature
7125 to protocol specification as well.
7127 Added functions: silc_server_send_remove_channel_user and
7128 silc_server_remove_channel_user into server.[ch].
7130 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7131 lib/silccore/silcpacket.h. However, they are not implemented
7134 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Fixed joining to a channel and sending channel messages
7137 between server and router. The channel message sending should
7138 now work inside a cell.
7140 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Fixed the private message sending between server and router.
7143 The private message sending should now work inside a cell.
7145 * Added silc_server_replace_id into server.[ch] to replace
7146 existing ID in the SILC network.
7148 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7149 and silc_idlist_replace_server_id into idlist.[ch] in server.
7151 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Fixed the server to server connections. Server can again now
7154 connect to router. Router to router connections probably does
7157 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Added dynamic protocol registering support. Now protocols can
7160 registered and unregistered on the fly. Patch by cras.
7162 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Added lib/contrib directory to hold routines that some platforms
7165 don't have but are needed by SILC.
7167 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7168 into lin/contrib to provide getopt() and getopt_long() for
7169 those who don't have it.
7171 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Added AWAY command to client. When away message is set and
7174 client receives a private message packet the client automatically
7175 replies to the sender with the away message.
7177 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7178 bug seemed to be the cause of recent problems when compiling
7181 * Added version detection support to SKE protocol specification
7182 and added the new changes to the SKE implementation as well.
7183 There were other minor changes in the SKE protocol as well.
7185 Many changes in lib/silcske/silcske.[ch] and in
7186 lib/silcske/payload.[ch].
7188 * Added ^U functionality, clear input line. Patch from cras.
7190 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7192 * Mainly small bugfixes on core library. Fixed some debugging
7193 logging and buffer overflow in silclog.c.
7195 * Updated config.sub and config.guess on the distribution tree.
7197 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Added command lagging support in server. Client may execute
7200 commands now only once in two seconds.
7202 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Optimized packet reception. MAC computation and checking is now
7205 also more optimized. A lot previously duplicated code is now
7206 used as generic by both client and server.
7208 * Fixed key pair generation in clientutil.c
7210 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Added into lib/silccore/silcbufutil.[ch] new function;
7213 silc_buffer_realloc.
7215 * Moved generic packet sending/encryption functions to
7216 lib/silccore/silcpacket.[ch] from client and server. Some
7217 rewriting of the functions.
7219 * Moved all generic packet reception/decryption functions to
7220 lib/silccore/silcpacket.[ch] from client and server. The
7221 packet processing is now much cleaner in both client and server.
7222 These were major changes in both client and server.
7224 * Created many common functions in server to do packet sending.
7225 Previously code were duplicated a lot, this has been removed
7228 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Rewrote major parts of the ID cache system. Don't know
7231 whether it is better now or not but at least the API is more
7234 * Major rewrite on ID cache stuff on client because of the ID
7235 cache API changes. Added idlist.c to client.
7237 * Also major rewrite on ID cache stuff on server as well.
7238 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7239 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7240 in hand, instead they are all put into the ID cache system now.
7241 All server_idlist_* routines uses ID cache now instead of
7242 traversing its own lists (those lists does not exist anymore).
7243 SilcIDList though still exists. Also, SilcXXXEntry's are
7246 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Finally made the SKE implementation compliant to the protocol
7249 specification. All mp integers are now binary encoded as
7250 opposed being HEX encoded.
7252 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7255 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7256 functions: silc_[encode/decode]_pem. Also added function
7257 silc_encode_pem_file to PEM encode with newlines ('\n') for
7260 * SILC public keys are now encoded either PEM or binary. Same
7261 option is for private keys as well. By default private keys
7262 are binary encoded and public keys PEM encoded. Silly HEX
7263 encoding were removed.
7265 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7266 function to create fingerprints.
7268 * Fixed a bug in SHA1; does not change the original data anymore.
7270 * Partly implemented INFO command on client and server side.
7271 Fixed CLEAR command. Changes to SERVER command; show current
7272 server(s) when giving command without arguments. Added
7273 VERSION command to client.
7275 * Added check to server that unregistered connections cannot
7276 execute commands (unless it is specificly allowed).
7278 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * Fixed screen refresh.
7282 * Fixed channel joining bug from client. On some circumstances
7283 client tried to join to a channel it had already joined.
7285 * Added public key verification process into client's protocol.c.
7286 The client now verifies the public key from user and saves
7287 it into ~./silc/serverkeys/ directory.
7289 Added into: clientutil.[ch]: silc_client_verify_server_key.
7291 * Changed SKE protocol's silc_ske_initiator_finish function
7292 to accept callback function that verifies the received public
7293 key. Removed old silc_ske_verify_public_key function.
7295 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7298 silc_pkcs_private_key[_data]_set.
7300 * Made the password and public authentication more cleaner in
7301 server's protocol.c.
7303 * Removed historic and obsolete protocol `channel_auth' from
7304 both client and server.
7306 * Removed wrong way of sending command status messages from
7307 server to client in server's command.c. The old way violated
7308 protocol specification.
7310 Changes to silccore/silccommand.[ch]: removed
7311 silc_command_encode_status_payload -> not needed anymore,
7312 changed silc_command_encode_payload_va to accept extra
7313 argument on variable argument list. The argument type must
7314 now be provided to the function. Also, added new function:
7315 silc_command_encode_reply_payload_va which is same as
7316 normal command_encode_payload_va except command status type
7317 is provided as extra argument.
7319 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added ~./silc directory handling. The directory includes the
7322 public and private keys for the client.
7324 Added silc_client_check_silc_dir, silc_client_create_identifier
7325 and silc_client_load_keys.
7327 * Implemented SILC protocol compliant public key. Added public
7328 and private key saving to and loading from files.
7330 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7331 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7332 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7333 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7334 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7336 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7337 silc_pkcs_load_[public/private]_key.
7339 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Added silc_server_get_route (route.[ch]) to get connection
7342 data for the fastest route for given ID.
7344 * Implemented INVITE command on client and server. The command
7345 were re-defined in the SILC Protocol Specification and the
7346 implementation now complies with the specification.
7348 * Implemented PING command on client and server.
7350 * Implemented NAMES command on client and server. The server side
7351 supports currently only normal server not router server yet.
7352 Some changes to NAMES definition in SILC protocol specification.
7354 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Implemented LEAVE command on client and server.
7358 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7359 again. This change was made to the protocol as well. Server
7360 should not violate the protocol specification anymore.
7362 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7365 was tested. SOCKS4 was not but should work anyway.
