38 * Added support for specifying multiple public keys for Client
39 connection section in server configuration file. This makes it
40 possible to accept multiple public keys from same host, or to
41 make a section that accepts any incoming host, and have the
42 accepted public keys listed in the section.
44 Added functions silc_sever_[find/get]_public_key, added the
45 support for this actually to all connection sections but only
46 the Client section is currently allowed to specify multiple

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

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

295 * Added new configuration options and blocks:
296 keepalive_secs, reconnect_count, reconnect_interval,
297 reconnect_interval_max, reconnect_keep_trying and
298 require_reverser_lookup. Added ConnectionParam block, and
299 implemented the connection parameters when connecting as
300 initiator and when accepting connections as responder.

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

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

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

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

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

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

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

535 * Removed TRQ from lib/trq, not needed anymore.
537 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
538 with server connections. Later this will be configurable
539 in config file after new config file is done. Affected file
542 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed a crash in server related to channel announcements.
545 Affected file silcd/server.c.
547 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed memory leaks in silc_server_create_new_channel*
550 functions. Affected file silcd/server.c.
552 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
553 which ID was changed. This way the router will send the
554 user list for the channel again, and server won't be in
555 desync in some rare circumstances. Affected file is
556 silcd/packet_receive.c.
558 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
560 * Check for NULL socket pointer in the function
561 silc_server_packet_send_to_channel_real. Affected file
564 * Fixed the BAN notify handling to correctly remove ban
565 list. Affected file silcd/packet_receive.c.
567 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Fixed some header addition to Toolkit distribution in
570 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
572 * Added lib/silcclient/client_ops_example.h as an template
573 file for application programmers to quickly start using
574 the SilcClientOperation functions in their application.
575 Updated the lib/silcclient/README as well to tell about this
576 nice file made available.
578 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
580 * Call silc_server_remove_from_channels when removing client
581 entry when NO_SUCH_CLIENT_ID was received. Affected file
582 is silcd/command_reply.c.
584 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
586 * Added server & router operator statistics updating. Affected
587 file silcd/packet_receive.c and silcd/command.c.
589 * Fixed the SERVER_SIGNOFF notify handling on normal server
590 not to save the history information for clients. Same was
591 fixed earlier in remove_clients_by_server function, but not
592 here. Affected file silcd/packet_receive.c.
594 * Raised the default connection-retry count from 4 to 7 in
595 server. Affected file silcd/server.h.
597 * Cancel any possible reconnect timeouts when we start the
598 key exchange. Affected file silcd/server.c.
600 * Do not reconnect on connection failure when SCONNECT was
601 given. Affected files silcd/server.[ch].
603 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
605 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
607 * Fixed the NICK command to always give the unformatted
608 nickname to the one giving the NICK command. If unformatted
609 nickname is cached already it will be formatted and the
610 local entry will always get the unformatted nickname.
611 Affected file lib/silcclient/idlist.c.
613 * Fixed some double frees from client library commands.
614 Affected file is lib/silcclient/command.c.
616 * Fixed CUMODE command in server to assure that no one can
617 change founder's mode than the founder itself, there was a
618 little bug. Affected file silcd/command.c.
620 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
622 * Removed the SilcClientCommandDestructor from the client
623 libary, it is not needed anymore. Affected files are
624 lib/silcclient/silcapi.h, command[_reply].[ch],
625 client_notify, idlist.c.
627 * Fixed GETKEY command to first resolve client, and then
628 resolve the server only if the client was not found, instead
629 of resolving both at the same time. Affected file is
630 lib/silcclient/command.c.
632 * Added silc_client_start_key_exchange_cb and lookup the
633 remote hostname and IP address before starting the key
634 exchange with server. The affected file is
635 lib/silcclient/client.c.
637 * The server's public key is now saved using the IP address
638 of the server and not the servername for the filename.
639 The hostname public key filename is checked as an fall back
640 method if the IP address based filename is not found.
642 Fixed the GETKEY command to save the fetched server key
645 Print the remote server's hostname now when new key is
646 received during connection process. Affected file is
647 irssi/src/silc/core/client_ops.c.
649 * Return always our own public key to the client if it asks
650 for it with GETKEY command. Affected file silcd/command.c.
652 * Removed the use_auto_addr variable from default config
653 file since it was in wrong section. Affected file is
656 * Fixed TOPIC_CHANGE notification to not route it when it
657 was sent using silc_server_send_notify_to_channel function.
658 Affected file silcd/command.c.
660 * Fixed silc_server_send_notify_kicked to send the kicker's
661 Client ID also, it was missing. Affected files are
662 silcd/command.c, silcd/packet_send.[ch].
664 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Do not save client history information in SERVER_SIGNOFF.
667 Fixes the bug in normal server that it does not detect
668 the client becoming valid after the server becomes back
669 online. Affected file silcd/server_util.c.
671 * Added `sock_error' field into the SilcSocketConnection
672 context. When error occurs during socket operation (read
673 or write) the error is saved. Added also new function
674 silc_socket_get_error to return human readable socket error
675 message. Affected files are lib/silcutil/silcsockconn.[ch],
676 lib/silcutil/unix/silcunixsockconn.c, and
677 lib/silcutil/win32/silcwin32sockconn.c.
679 * The server now prints the socket error message in the
680 signoff for client. Affected file silcd/server.c.
682 * Fixed the `created' channel information sending from router
683 to server in JOIN command. Checks now whether the channel
684 really was created or not and set it according that.
686 Fixed the JOIN command to use the client entry's current
687 ID during the joining procedure instead of the one it sent
688 in the command (it is checked though), since it can change
689 between the packet processing and command processing, and
690 would just case unnecessary pain in the client end. Affected
691 file silcd/command.c.
693 * Fixed a channel key payload sending to use correct channel
694 ID when the server was forced to change the channel's ID by
695 router. Router sent the key payload with the old Channel ID.
696 Affected file silcd/packet_receive.c.
698 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Call silc_server_save_channel_key only if the key payload
701 was provided in the JOIN command's command reply. Affected
702 file silcd/command_reply.c.
704 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Fixed silc_mp_sizeinbase to return the value correctly with
707 MPI. Affected file lib/silcmath/mp_mpi.c.
709 * Fixed the stop_server signal to correctly stop the scheduler
710 and gracefully stop the server when SIGTERM or SIGINT signals
711 are received. Affected file silcd/silcd.c.
713 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
715 * Simple handling of TERM and HUP signals. Also added some log
716 flushing call around. Affected file is
719 * Fixed small bugs in silclog.c. Now buffering output will take
720 effect after 10 seconds since startup: This will ensure that
721 no important startup messages are lost. Also output redirection
722 will preserve original format ([Date] [Type] message).
723 Affected file is lib/silcutil/silclog.c.
725 * Added two options to the config file, in the logging section:
726 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
727 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
729 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
731 * Do not print the warning about log files not being initialized
732 more than once to avoid excess logging. Affected file is
733 lib/silcutil/silclog.c.
735 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
736 the SIM copying in make install in Makefile.am.pre.
738 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
740 * Rewritten silclog APIs. Globally interesting changes follows:
741 silc_log_set_files() changed to silc_log_set_file().
742 silc_log_set_callbacks() changed to silc_log_set_callback().
743 ROBOdoc documented silclog header file.
744 SilcLogCb now returns bool to wether inihibit the default
745 handler or not (to keep the old behaviour return always TRUE).
746 The new APIs should also fix the problem of the
747 silcd_error.log file that was written in the current directory.
750 Log files streams will remain opened after silc_log_set_file()
751 call, means less CPU usage notably on high traffic servers.
752 File streams are now full buffered, and flushed to the disk
753 every 5 minutes, lesses HD activity and CPU usage.
754 Messages can be redirected, allowing admins to configure
755 one single logfile for all server messages.
756 the silc_log_quick global variable to activate fast-logging.
757 Affected files lib/silcutil/silclog.[ch]
759 * Changed some code to conform new silclog APIs. Affected
760 files are doc/example_silcd.conf.in, silcd/server.c
761 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
764 * Fixed a memory leak that could occur in some situations.
765 Affected file silcd/serverconfig.c.
767 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
769 * Added the silc_client_del_client to remove the client from
770 all channels as well. Affected file lib/silcclient/idlist.c.
772 * Fixed the client library to correctly remove the client
773 from all channels when the client entry is being destroyed.
774 Affected file lib/silcclient/client_notify.c, command.c.
776 * Added auto-nicking support to the client library. If the
777 applicatio now sets client->nickname it will be sent to the
778 server after connecting by the library. This way for example
779 SILCNICK (or IRCNICK) environment variables will have effect
780 and always change the nickname automatically to whatever
781 it is wanted. Affected file lib/silcclient/client.[ch].
783 * Renamed silc_server_command_bad_chars to the
784 silc_server_name_bad_chars and moved it to the
785 silcd/server_util.[ch]. Added also new function
786 silc_server_name_modify_bad to return nickname that
787 includes bad characters as new nickname without those
788 bad characters. This check and modify is now used in
789 silc_server_new_client when the username is initially set
790 as nickname, so it must be checked to be valid nickname.
791 Affected file silcd/packet_receive.c.
793 * The nickname length is now taken from the packet for real
794 and not trusted to strlen() since it clearly can return
795 wrong length for nickname including bad characters. This
796 also applies to channel names. Affected file silcd/command.c.
798 * Removed the lib/silcsilm/modules directory. Modules are now
799 compiled into the lib/silcsim. Fixed the copying of the
800 modules to follow symbolic links in Makefile.am.pre.
802 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Fixed silc_string_regexify list creation. Fixes bugs with
805 BAN and INVITE commands in server. The affected file is
806 lib/silcutil/unix/silcunixutil.c.
808 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Removed the command destructor entirely from the server's
811 command and command reply routines. It is not needed, and
812 its usage was buggy and caused crashes. Affected files are
813 silcd/command[_reply].[ch].
815 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
817 * Cancel protocol and NULL sock->protocol if timeout
818 occurred during protocol. Affected file silcd/server.c.
820 * Cancel protocol timeouts always before calling the final
821 callback, to assure that after final callback is called
822 no other state will be called for the protocol anymore.
823 Affected file silcd/protocol.c.
825 * Print error log if incoming connection configuration could
826 not be found. Affected file silcd/server.c.
828 * Fixed JOIN command to correctly save the founder mode
829 to the client on normal SILC server, when the channel
830 was created by the router. Affected file silcd/command.c.
832 * Fixed LIST command (hopefully) to send correct reply
833 packets. Affected file silcd/command.c.
835 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
837 * The silc_packet_receive_process now returns FALSE if the
838 read data was invalid packet, and TRUE if it was ok.
840 The server now checks that if unauthenticated connection
841 sends data and its processing fails the server will close
842 the connection since it could be a malicious flooder.
844 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
846 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Make sure the warning about error opening a log file is
849 printed only once and not everytime it fails (produces
850 too much useless log). Affected file lib/silcutil/silclog.c.
852 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
854 * Made the silc_server_daemonise() function more readable.
855 Affected file silcd/server.c.
857 * Pid file is now optional, the user may comment it out from
858 the config file. Removed define SILC_SERVER_PID_FILE, we
859 don't need a default any longer. Affected file
860 configure.in.pre, lib/Makefile.am.pre.
862 * Make some use of the pid file. The server now dies at startup
863 if it detects a valid pid file on his path. The server would
864 die anyway in this circumstance, because of the bind() failure.
865 Affected file silcd/silcd.c.
867 * No longer compiling lib/dotconf.
869 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Fixed JOIN command parsing not to crash. Affected file
872 lib/silcclient/command.c.
874 * Fied the NICK_CHANGE notify to add the new client entry
875 even it is resolved. This removes an <[unknown]> nick
876 thingy bug in the client. Affected file is
877 lib/silcclient/client_notify.c.
879 * Do not try to allocate 0 bytes (efence does not like it)
880 in lib/silccore/silccomand.c when encoding payload.
882 * Do not take IRCNICK as nickname in Irssi SILC client since
883 it is not possible to set nickname before hand connecting
884 the server (TODO has an entry about adding auto-nicking
887 * Changed the silc_server_command_pending to check whether
888 there already exists an pending entry with the specified
889 command, command identifier and pending callback. This is
890 to fix IDENTIFY and WHOIS related crashes that may register
891 multiple pending commands with same identifier. Affected
892 file silcd/command.c.
894 * Fixed the server to reconnect to the router even if it
895 was already reconnecting and EOF was received. This to
896 fix a possibility that the server wouldn't ever try to
897 auto-reconnect to the router. Affected file silcd/server.c.
899 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Fixed the server's password authentication to use the
902 length of the locally saved password, and not the one
903 sent in the packet. Affected file silcd/protocol.c.
905 * Fixed same password authentication problem in the
906 Authentication Payload handling routines in
907 lib/silccore/silcauth.c.
909 * Yet another password authentication problem fixed with
910 channel password handling in silcd/command.c.
912 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
914 * If first character of string in silc_parse_userfqdn is '@'
915 then do not parse it. Affected file is
916 lib/silcutil/silcutil.c.
918 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Fixed minor bug in IDENTIFY command reply sending, which
921 caused various weird problems during JOIN when it was
922 resolving names for users. Affected file silcd/command.c.
924 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Fixed the IDENTIFY command reply sending to chech better valid
927 clients. It was possible to send incomplete list of replies.
928 Affected file silcd/command.c.
930 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Added silc_client_command[s]_[un]register functions now to
933 dynamically register the commands in client library. Removed
934 the static table of commands. This allows the client library
935 to call commands without causing the application to know about
936 what commands library has called.
938 Removed the INFO command reply kludge to detect when the command
939 was called by library. Now library use its own command reply
940 function for INFO command.
942 Added function silc_client_command_call to call a command.
943 Application can use it to call command, not access the structure
946 Now all commands that are sent by the client library (not
947 explicitly sent by application) use own command reply functions.
949 Affected files around lib/silcclient/ and in
950 irssi/src/silc/core/.
952 * Fixed the WHOIS command reply sending to chech better valid
953 clients. It was possible to send incomplete list of replies.
955 Fixed the WHOIS and IDENTIFY to send the request to router
956 if normal server did not do it and did not find any results.
958 Affected file silcd/command.c.
960 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Moved the internal data from SilcClient context into its
963 own file, not accesible to application. Affected files
964 lib/silcclient/client.h and lib/silcclient/client_internal.h,
965 and other files in client library.
967 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
969 * Added doc/examples installation target in Makefile.am.pre.
972 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
974 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
975 commands the found client entry will be removed from the
976 cache, after notifying application about the error. Affected
977 file lib/silcclient/command_reply.c.
979 * Changed the /MSG to check for exact nickname user gave, and
980 not let `nick' match `nick@host' if it is only one found. Now,
981 user must type the exact nickname (like nick@host2) even if
982 there are no more than one same nicks found. This is to avoid
983 a possibility of sending nickname to wrong nickname since
984 `nick' could match `nick@host'. Affected file is
985 irssi/src/core/silc-servers.c.
987 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Do not print "you are now server operator" or similar when
990 giving /away command. Affected files are
991 irssi/src/silc/core/client_ops.c, silc-servers.h.
993 * Made the silc_server_command_pending_error_check to send
994 the same command reply payload it received back to the
995 original sender of the command. This way all arguments
996 that was received by the server will be received by the
997 client too. Affected file silcd/command.c.
999 * Added the silc_idcache_add to return the created cache entry
1000 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1002 * Add global clients to expire if they are not on any channel.
1003 This is because normal server will never know if they signoff
1004 if they are not on any channel. The cache expiry will take
1005 case of these entries. This is done by normal servers only.
1006 The affected files are silcd/command_reply.c,
1007 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1009 * If server receives invalid ID notification for WHOIS or
1010 IDENTIFY and the ID exists in the lists, it is removed.
1011 Affected file silcd/command_reply.c.
1013 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1014 in client then client entry that it matches is searched and
1015 the nickname is printed on the screen for user. Affected
1016 file irssi/src/silc/core/client_ops.c.
1018 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Use cache entry expire time in the LIST command reply to
1021 purge old entries from the cache after the LIST command
1022 reply has been received. This way we don't have non-existent
1023 entries in the cache for too long. Affected file is
1024 silcd/command_reply.c.
1026 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * If we are normal server, and we've not resolved client info
1029 in WHOIS or IDENTIFY from router, and it is global client,
1030 we'll check whether it is on some channel. If it is not
1031 then we cannot be sure about its validity and will resolve it
1032 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1033 file silcd/command.c.
1035 * Search channel by name (if possible) rather than by ID
1036 in IDENTIFY command's command reply. Affected file is
1037 silcd/command_reply.c.
1039 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1042 Updated specs and implemented it. Affected file silcd/command.c,
1043 silcd/packet_send.c and silcd/packet_receive.c.
1045 * Implemented the <founder auth> payload handling in the JOIN
1046 command. If provided all conditions for channel joining
1047 except requirement to provide correct passphrase can be
1048 overrided by the channel founder. Updated the protocol specs.
1049 Affected file silcd/command.c.
1051 Added support for founder auth in JOIN command in client
1052 library. Fixed the parsing of the JOIN command now to support
1053 all options as they should be. The affected file is
1054 lib/silcclient/command.c.
1056 * Optimized the WHOIS and IDENTIFY commands to send the request
1057 to router only if it includes nicknames or other names. If
1058 they include only IDs then check the local cache first before
1059 routing. Affected file is silcd/command.c.
1061 * Added channels topic announcements. Affected file is
1062 silcd/packet_receive.c and silcd/server.c.
1064 * Fixed the silc_server_send_notify_topic_set to really destine
1065 the packet to channel. Affected file silcd/packet_send.c.
1067 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1068 library. Affected file lib/silcclient/client_notify.c.
1070 * Added UMODE announcements. Affected file silcd/server.c.
1072 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Memory leak fixes in:
1076 lib/silcutil/silcsockconn.c
1077 lib/silcske/silcske.c
1078 lib/silcske/groups.c
1080 lib/silccrypt/silcpkcs.c
1081 lib/silccore/silccommand.c
1082 lib/silccore/silcidcache.c
1087 * ROBOdoc documented the lib/silcske/groups.h file and a
1088 bit changed the interface for better.
1090 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1092 * Update the client entry context in the ID cache after
1093 nick change. Affected file lib/silcclient/command.c.
1094 Fixes the CUMODE command when regaining founder privileges,
1095 and a little WHOIS problem.
1097 * Fixed silc_net_gethostbyname to correctly call the
1098 inet_ntop. Affected file lib/silcutil/silcnet.c.
1100 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1102 * Added IPv6 support checking to the configure.in.pre, added
1103 also --enable-ipv6 option to override the check. Affected
1104 file configure.in.pre.
1106 * The silc_thread_create now calls the start function
1107 directly if threads support is not compiled in. Removes
1108 ugly #ifdef's from generic code. Affected files are
1109 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1111 * Added silc_net_gethostby[name/addr]_async to asynchronously
1112 resolve. Affected files are lib/silcutil/silcnet.[ch].

1123 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1124 routines. Added silc_net_is_ip[4/6]. Affected file is
1125 lib/silcutil/unix/silcunixnet.c. All routines that take
1126 address as argument now supports both IPv4 and IPv6 addresses.
1128 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1130 * Fixed LIST command reply sending in server. Affected file
1133 * Server now sends the kicker's client ID in the KICK notify
1134 to the kicked client. Affected file silcd/command.c.
1136 * The client library now parses the kickers client ID and
1137 UI displays it. Affected files lib/silcclient/client_notify.c
1138 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1140 * Made all payload parsing function prototypes consistent.
1141 They all take now const unsigned char * and uint32 pair as
1142 the payload data instead of SilcBuffer. Changes all around
1143 the source tree. Other unsigned char* -> const unsigned char*
1144 changes around the tree as well.
1146 * Optimized SFTP client and server packet sending not to
1147 allocate new buffer for each packet but to recycle the
1148 first allocated buffer. Affected files are
1149 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1151 * Optimized the SFTP client to use SilcList instead of
1152 SilcDList for requests, because it is faster. Affected file
1153 is lib/silcsftp/sftp_client.c.
1155 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1156 into lib/silccore/silcid.[ch].
1158 Renamed silcpayload.[ch] into silcargument.[ch].
1160 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * If client entry is deleted with active key agreement
1163 session, abort the session.
1165 The silc_client_abort_key_agreement now calls the completion
1166 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1168 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1171 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * Don't use __restrict in older GCC's. Affected file is
1174 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1176 * silc_net_localhost now attempts to reverse lookup the
1177 IP/hostname. Affected file lib/silcutil/silcnet.c.
1179 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1180 command. It can be used to gain founder privileges at
1181 the same time when joining the channel.
1183 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1184 kicker's client ID as well. Updated protocol specs.
1186 Defined that the server must send SILC_COMMAND_IDENTIFY
1187 command reply with error status to client who sent
1188 private message with invalid client ID.
1190 Updated the protocol specification.
1192 * Added silc_server_send_command_reply to send any
1193 command reply. Affected file silcd/packet_send.[ch].
1195 * Added silc_id_payload_encode_data to encode ID payload
1196 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1198 * The server now send IDENTIFY command reply with error
1199 status if client ID in private message is invalid. Affected
1200 file silcd/packet_receive.c.
1202 * Save the server key file with server's IP address in
1203 the filename instead of hostname. The affected file is
1204 irssi/src/silc/core/client_ops.c.
1206 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1211 * Added libtool support for compiling shared objects in
1212 lib/silcsim. Affected file configure.in.pre and
1213 lib/silcsim/Makefile.am. Original patch by cras.
1215 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Pid file configuration, and server's config file fixes
1218 patch by toma. Updated CREDITS file.
1220 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Fixed silc_client_channel_message to not try to decrypt
1223 the message twice if it resolved the destination client
1224 information. This could cause of dropping one channel
1225 message. Affected file lib/silcclient/client_channel.c.
1227 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1230 lib/silcclient/client.c. This function is used when the SILC
1231 Client is run under some other scheduler, or event loop or
1232 main loop. On GUI applications, for example this may be
1233 desired to used to run the client under the GUI application's
1234 main loop. Typically the GUI application would register an
1235 idle task that calls this function multiple times in a second
1236 to quickly process the SILC specific data.
1238 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1240 * Fixed silc_server_drop() for dropping the supplementary
1241 groups as well, this could cause a security hole on some
1244 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1249 * Write PID file after dropping privileges. Added -F option
1250 to run server on foreground. A patch by debolaz.
1251 Affected files silcd/server.c, silcd/silcd.c.
1253 * Fixed MOTD to return the MOTD file server name. Affected
1254 file silcd/command.c.
1256 * Added INFO command reply handling to the Irssi SILC Client.
1257 Affected file irssi/src/silc/core/client_ops.c.
1259 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1261 * Fixed the silc_idcache_list_* routines to really support
1262 the dynamic list. Fixes a crash. Affected file is
1263 lib/silccore/silcidcache.c.
1265 * Fixed the LIST command reply to really call LIST command's
1266 pending callbacks. Affected file silcd/command_reply.c.
1268 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Update conn->local_entry->nickname after giving NICK
1271 command. Affected file lib/silcclient/command.c.
1273 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1275 * Added the [pid] option to the silcd configuration file
1277 Affected files: serverconfig.[ch] and silcd.c
1279 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Save fingerprint in WHOIS command reply in server.
1282 Affected file silcd/command_reply.c.
1284 * Fixed NICK commands pending callback registration.
1285 Affected file lib/silcclient/command.c.
1287 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Use ++server->cmd_ident when sending commands in server,
1290 instead of random number. Affected file silcd/command.c.
1292 * Fixed GETKEY command reply to call actually GETKEY pending
1293 command callbacks. Affected file silcd/command_reply.c.
1295 * A bit stricter check for nicknames. Check for same nickname
1296 in NICK command also. Affected file silcd/command.c.
1298 * Do not call INFO command everytime client ID changes, only
1299 during first connecting. Affected file lib/silcclient/client.c.
1301 * Set the new nickname only after successful command reply for
1302 NICK command is returned by server. Affected file
1303 lib/silcclient/command.c.
1305 * Remove nicknames from nicklist during server_signoff notify.
1306 Should fix /NAMES bit more. The affected file is
1307 irssi/src/silc/core/silc-channels.c.
1309 * Added `fingerprint' field to the SilcIDListData in the
1310 silcd/idlist.h to hold the fingerprint of the client's
1313 Send the fingerprint of the client's public key in WHOIS
1316 Affected files silcd/command.c, and silcd/idlist.[ch].
1318 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1319 create fingerprint from given data.
1321 * Show the fingerprint of the client's public key in WHOIS.
1322 Affected files irssi/src/module-formats.[ch] and
1323 irssi/src/silc/core/client_ops.c.
1325 * Format the multiple same nicknames also during JOIN and
1326 NICK_CHANGE notifys. Affected file is
1327 lib/silcclient/client_notify.c.
1329 * Do not print error on screen for invalid private message
1330 payload since it can come if someone is sending private
1331 messages with wrong key. Affected file
1332 lib/silccore/silcprivate.c.
1334 * Fixed multiple concurrent /PING crash. Affected file
1335 lib/silcclient/command.c.
1337 * Changed the wrong ID encoding. All IP addresses must be
1338 in MSB first order in encoded format. They were encoded
1339 wrong and was in LSB format. Affected files are
1340 silcd/serverid.c, lib/silcutil/silcutil.c.
1342 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1344 * Call the `connect' client operation through the scheduler
1345 in case of error. Affected file lib/silcclient/client.c.
1347 * Call the `failure' client operation even if the error
1348 occurred locally during a protocol. Affected file is
1349 lib/silcclient/protocol.c.
1351 * Added support of sending LIST command to router from normal
1352 server. This way normal server can get list of all channels
1353 in the network too. Fixed the channel list sending in the
1354 server too. Affected files are silcd/command.c, and
1355 silcd/command_reply.[ch].
1357 * Added silc_server_update_channels_by_server and
1358 silc_server_remove_channels_by_server. They are used during
1359 disconnection of primary router and in backup router protocol.
1360 Affected file silcd/server_util.[ch], silcd/server.c and
1361 silcd/server_backup.c.
1363 * Fixed channel adding to global list in IDENTIFY command
1364 reply in server. Affected file silcd/command_reply.c.
1366 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * If the incoming packet type is REKEY or REKEY_DONE process
1369 that packet always synchronously. Fixes yet another MAC
1370 failed error on slow (dialup) connections. Affected file
1371 lib/silcclient/client.c and silcd/server.c.
1373 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Call check_version SKE callback for initiator too. Affected
1376 file lib/silcske/silcske.c.
1378 * Implemented fix for security hole found in the SKE that was
1379 fixed in the specification few days back; the initiator's
1380 public key is now added to the HASH value computation.
1381 Added backwards support for the old way of doing it too, for
1382 old clients and old servers. Affected file is
1383 lib/silcske/silcske.c.
1385 * Enabled mutual authentication by default in SKE. If initiator
1386 is not providing mutual authentication the responder will
1387 force it. This will provide the proof of posession of the
1388 private key for responder. The affected files are
1389 lib/silcclient/protocol.c and silcd/protocol.c.
1391 * Do not cache anymore the server's public key during SKE.
1392 We do mutual authentication so the proof of posession of
1393 private key is done, and if the server is authenticated in
1394 conn auth protocol with public key we must have the public
1395 key already. Affected file silcd/protocol.c.
1397 * Added new global debug variable: silc_debug_hexdump. If
1398 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1399 file lib/silcutil/silclog.[ch].
1401 * Fixed compilation warning due to char * -> const char *.
1402 Affected files lib/silcutil/silcnet.h, and
1403 lib/silccore/silcauth.[ch].
1405 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed CMODE command when new channel key was created. If
1408 the creation failed the old key was removed. Next time giving
1409 same command would crash the server since the old key was
1410 freed already. Affected file silcd/command.c.
1412 * Fixed the silc_server_announce_get_channels to not crash
1413 on reconnect. Affected file silcd/server.c.
1415 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Added silc_log_set_debug_string function to set a regex
1418 string to match for debug output. Only the function names,
1419 or filenames matching the given debug string is actually
1420 printed. This way it is possible to filter out those debug
1421 strings that user is not interested in.
1423 Fixed a bug in silc_string_regexify.
1425 Affected files lib/silcutil/silclog.[ch], and
1426 lib/silcutil/unix/silcunixutil.c.
1428 * Changed the -d options in both server and Irssi SILC client
1429 to take the debug string as argument. Affected files
1430 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1432 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Added silc_hash_babbleprint to create a Bubble Babble
1435 Encoded fingerprint. The encoding is developed by Antti
1436 Huima (draft-huima-babble-01.txt), and it creates human
1437 readable strings out of binary data. Affected file
1438 lib/silccrypt/silchash.[ch].
1440 * Print the babble print now in addition of fingerprint as well
1441 in Irssi SILC client. Affected files are
1442 irssi/src/fe-common/silc/module-formats.[ch],
1443 irssi/src/fe-common/silc/core/client_ops.c.
1445 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Fixed a security problem found in SKE. The initiator's
1448 public key too is now added to the HASH hash value creation
1449 which is signed by the responder to create the SIGN value.
1450 This will prevent anyone in the middle to lie to the responder
1451 about the initiator's public key. If this is done now, the
1452 man in the middle will get caught. Updated the protocol
1455 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Better installation directory handling. Configure module
1458 paths and other paths automatically to example_silc* files
1459 in doc/. A patch by toma.
1461 * Fixed compiler warning from MPI library, and from SILC RNG.
1464 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1465 It can be configured with ./configure. A patch by toma.
1467 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Find correct make to use in prepare-clean. A patch by
1470 toma. Affected file prepare-clean.
1472 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1474 * Added irssi variables use_auto_addr, auto_bind_ip,
1475 auto_bind_port and auto_public_ip.
1477 * Changed the interface for silc_client_send_key_agreement
1478 in lib/silcclient/silcapi.h
1482 irssi/src/silc/core/silc-core.c
1484 lib/silcclient/silcapi.h
1485 irssi/src/silc/core/silc-channels.c
1486 lib/silcclient/client_keyagr.c
1489 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Added silc_pkcs_public_key_compare to compare two
1492 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1494 * Check that the client who set the founder mode on the
1495 channel is the same client that is giving the founder
1496 mode to itself. It is done by comparing the saved public
1497 key (it is saved even in the authentication is passphrase).
1498 Affected file silcd/command.c.
1500 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Do not process packet for disconnected socket connection.
1503 Affected file lib/silccore/silcpacket.c.
1505 * Process the DISCONNECT packet through scheduler in the
1506 client library. Affected file lib/silcclient/client.c.
1508 * Fixed the silc_client_packet_parse to not to increase
1509 the packet sequence number if the conn->sock and the
1510 current socket connection is not same. This can happen
1511 for example during key agreement when the conn includes
1512 multiple socket connections (listeners). Affected file
1513 lib/silcclient/client.c.
1515 * The sender of the file transfer request now provides also
1516 the pointer (listener) for the key exchange protocol. If
1517 the listener cannot be created then it sends empty key
1518 agreement and lets the receiver provide the listener.
1520 Added `local_ip' and `local_port' arguments to the
1521 silc_client_file_send. If they are provided they are used,
1522 if not then it will attempt to find local IP address, if
1523 not found or bind fails then the remote client will provide
1526 Affected files are lib/silcclient/client_ftp.c and
1527 lib/silcclient/silcapi.h.
1529 * Extended the FILE SEND command to support defining the
1530 local IP and port for key exchange listener. They are
1531 optional. Affected file irssi/src/silc/core/silc-servers.c.
1533 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Defined to WHOIS command reply the sending of fingerprint
1536 of the client's public key (if the proof of posession of the
1537 corresponding private key is verified by the server).
1538 Updated to the protocol specification.
1540 * Added support of receiving the client's public key's
1541 fingerprint in command reply in client library. Affected
1542 file is lib/silcclient/command_reply.c, and
1543 lib/silcclient/idlist.[ch].
1545 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Do not send over 128 chars long nickname to the server
1548 in NICK command. Affected file lib/silcclient/command.c.
1550 * Do not send over 256 chars long channel names to the server
1551 in JOIN command. Affected file lib/silcclient/command.c.
1553 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * Assure that silc_server_close_connection cannot be called
1556 twice for same socket context. Affected file is
1559 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Send error message to application if opening file for
1562 writing during file transfer fails. Affected file is
1563 lib/silcclient/client_ftp.c.
1565 Remove all file transfer sessions for a client that we're
1566 removing from ID cache.
1568 Affected file is lib/silcclient/client_ftp.c.
1570 * Fixed silc_net_addr2bin to return correct address. Affected
1571 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1573 * Fixed file transfer session removing on signoff notify.
1574 Affected file irssi/src/silc/core/silc-servers.c.
1576 * Added the SilcClientFileError to be returned in the monitor
1577 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1578 Affected file lib/silcclient/silcapi.h.
1580 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Fixed a crash in silc_client_ftp_free_sessions and
1583 silc_client_ftp_session_free_client. Affected file
1584 lib/silcclient/client_ftp.c.
1586 * Added `disabled' field in the SilcChannelEntry in the server
1587 to indicate if the server entry is disabled. Affected file
1588 silcd/idlist.h, silcd/command[_reply].c.
1590 * SILC server adds now /var/run/silcd.pid everytime it is
1591 started. Affected file silcd/silcd.c.
1593 * Added silc_server_packet_send_clients to send a packet to
1594 the provided table of client entries. Affected file
1595 silcd/packet_send.[ch].
1597 * Fixed a crash in client resolving in client_prvmsg.c in
1598 client library. Affected file lib/silcclient/client_prvmsg.c.
1600 * Do not actually remove the client directly from ID cache
1601 during SERVER_SIGNOFF, but invalidate it. This way we
1602 preserve the WHOWAS info for the client. Affected file
1603 silcd/server_util.c.
1605 * Fixed SERVER_SIGNOFF notify handling in the server. The
1606 server is now able to process incoming SERVER_SIGNOFF notify
1607 for a server that it doesn't even know about. It will remove
1608 the clients provided in the notify. Affected file
1609 silcd/packet_receive.c.
1611 * Check for partial packet in data queue after every packet that
1612 was found from the queue. Return and wait for more data if
1613 there is partial data in queue. Affected file is
1614 lib/silccore/silcpacket.c.
1616 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Added SilcClietFileError enum to indicate error in
1619 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1620 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1621 Affected files lib/silcclient/silcapi.h and
1622 lib/silcclient/client_ftp.c.
1624 * Check that newsize in silc_buffer_realloc is larger than
1625 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1627 * Added better monitor of file transfers. It now monitors
1628 key agreement protocol during the file transfer too. Added
1629 error reporting too. Affected files
1630 irssi/src/silc/core/silc-servers.c,
1631 irssi/src/fe-common/silc/module-formats.[ch].
1633 * Wrote a help file for FILE command.
1635 * Added silc_rng_global_get_byte_fast to get not-so-secure
1636 random data as fast as possible. Random data is read from
1637 /dev/urandom if available and from the SILC RNG if not
1638 available. It is used in padding generation. Affected file
1639 lib/silccrypt/silcrng.[ch].

1650 if make install is given. Affected files: all Makefile.am's.
1652 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Assure that silc_client_notify_by_server_resolve does not
1655 resolve the client information multiple times. If it cannot
1656 be found by the first it cannot be found at all. Affected
1657 file lib/silcclient/client_notify.c.
1659 * Fixed WHOWAS command reply calling. Affected file
1660 lib/silcclient/command_reply.c.
1662 * Removed all references to silc_idlist_get_client from the
1663 Irssi SILC client since that call is internal call used by
1664 the library. The Irssi SILC client will use now client
1665 retrieval functions found in silcapi.h.
1667 * Fixed a bug in resolving nickname info before sending
1668 private message. It used freed memory. Affected file
1669 irssi/src/silc/core/silc-servers.c.

1690 * Added silc_net_localip to return local host's IP address.
1691 Affected file lib/silcutil/silcnet.[ch].
1693 * If key exchange or rekey protocol is active for a connection
1694 parse all packets syncronously since there might be packets
1695 in packet queue that we are not able to process without first
1696 processing packets before them. Affected file silcd/server,
1697 lib/silcclient/client.c.
1699 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1700 whether library should continue processing the packet.
1701 Affected file lib/silccore/silcpacket.h.

1736 * Resolve the client info when received private message or
1737 channel message for a client which nickname we don't know.
1738 Affected files lib/silcclient/client_prvmsg.c and
1739 lib/silcclient/client_channel.c.
1741 * Do not crash in /KEY if client is not connected. Affected
1742 file irssi/src/silc/core/silc-channels.c.
1744 * Added SilcClientStatus field to the SilcClientEntry in the

1747 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1748 is incomplete and is being resolved, it won't be resolved
1751 Make sure also that USERS command reply does not resolve
1752 twice information. Affected file is
1753 lib/silcclient/command_reply.c.
1755 Make sure that silc_client_get_clients_by_list does not
1756 resolve twice same information.
1758 * Check for valid client->id in the silc_server_free_client_data.
1759 Affected file silcd/server.c.
1761 * Fixed /GETKEY nick@server not to crash if the server entry
1762 is not found. Affected file lib/silcclient/command.c.

1770 Affected file silcd/command.c.
1772 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Call the silc_server_udpate_servers_by_server in the
1775 primary router that comes back online in the backup resuming
1776 protocol. Otherwise it routes packets wrong. Affected file
1777 silcd/server_util.[ch], silcd/server_backup.c.
1779 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1782 lib/silcutil/silcbuffmt.[ch].
1784 * Redefined the SILC packet header to include the padding
1785 length. Affected file lib/silccore/silcpacket.[ch].
1787 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1788 length for maximum padding up to 128 bytes). Affected
1789 file lib/silccore/silcpacket.h.
1791 * Removed all backwards support for old 0.5.x MAC thingies.
1792 The SILC packet header change makes it impossible to be
1793 backwards compatible.
1795 * Send the ENDING packet with timeout in the backup resuming
1796 protocol. This is to assure that all routers has connected
1797 to the primary router. Affected file silcd/server_backup.c.
1799 * Changed the RNG to take the first IV from random data. It
1800 used to take it from zero actually. Changed the RNG also
1801 to use /dev/urandom during session. /dev/random is used
1802 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1804 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Changed the SILC packet header to have the first two bytes
1807 (the packet length) encrypted. Affected files aroung the
1808 code tree, lib/silccore/silcpacket.[ch]. Removed the
1809 SilcPacketCheckDecrypt callback. It is not needed anymore
1810 since the silc_packet_receive_process will determine now
1811 whether the packet is normal or special.
1813 * Implemented the unidirectional MAC keys. Affected files
1814 lib/silcske/silcske.c, silcd/protocol.c and
1815 lib/silcclient/protocol.c.
1817 * Implemented the packet sequence number to the MAC computation.
1818 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1819 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1820 lib/silcclient/protocol.c.
1822 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Allow backup router to announce servers. All servers
1825 announced by backup router are added to the global list
1826 automatically. Update hte server's socket to our primary
1827 router also when backup router announces a server.
1828 Affected file silcd/packet_receive.c.
1830 * Do not update the client->router in the function
1831 silc_server_udpate_clients_by_server if the client is on
1832 global list. We might fail to find any specific server
1833 for locally connected clients and local cell clients. They
1834 should still use the `from' and not `to' as client->router.
1835 This fixes backup router resuming protocol. Affected file
1836 silcd/server_util.c.
1838 * Decrease channel statistics count only if the channel
1839 deletion worked. Affected files are silcd/server.c and
1840 silcd/server_util.c.
1842 * Added silc_server_update_servers_by_server to update origin
1843 of all server entries. Used during backup router protocol.
1844 Affected files silcd/server_util.[ch], silcd/server.c. and
1845 silcd/backup_router.c.
1847 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1848 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1849 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1850 lib/silccrypt/silchmac.c.
1852 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Assure that router cannot reroute the same channel message
1855 to the sender. Affected file silcd/packet_receive.c.
1857 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Made better checks that the channel message is not sent
1860 to the router it came from. Affected file is
1861 silcd/packet_send.c. Fixed memory leak too.
1863 * Announce informations for incoming router connection, but
1864 only after checking if it is replaced by backup router.
1865 Affected file silcd/packet_receive.c.
1867 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Fixed the backup resuming protocol to work in multiple
1870 router environment. Affected file silcd/server_backup.c.
1872 * Route packet only to one router in the function
1873 silc_server_packet_send_to_channel. Affected file is
1874 silcd/packet_send.c.
1876 * Fixed silc_server_send_notify_dest to set the broadcast
1877 flag. Fixed the silc_server_send_notify_topic to actually
1878 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1879 Affected file silcd/packet_send.c.
1881 * Changed the SFTP Filesystem interface. Changed the
1882 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1883 the filesystem operation function. The SilcSFTPFilesystem
1884 is now a context that is allocated by all filesystem allocation
1885 functions and it already includes the operations structure
1886 and filesystem specific context. It is given as argument
1887 now to the silc_sftp_server_start. This made the interface
1888 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1889 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1891 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Changed the backup router adding and getting interfaces
1894 in the server. The router that will be replaced by the
1895 specified backup router is now sent as argument. Affected
1896 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1899 * Added silc_net_addr2bin_ne to return the binary form of
1900 the IP address in network byte order. Affected files
1901 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1903 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Check for existing server ID in silc_server_new_server
1906 and in silc_server_connect_to_router_final and remove the
1907 old entry if it exists. Affected file silcd/packet_receive.c,
1910 * Send the channel message always to only one router, either
1911 in upstream or downstream. Affected file is
1912 silcd/packet_send.c.
1914 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Wrote the definition of the backup resuming protocol to the
1917 protocol specification.
1919 * Removed one redundant channel key generation from normal
1920 server during joining procedure. Removed one redundant
1921 channel key sending from server to router during joining
1922 procedure. Affected file silcd/command.c.
1924 * Made minor bugfixes to the backup router resuming protocol.
1925 Affected file silcd/server_backup.c, server.c.

1930 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1933 * Implemented the backup resuming protocol that is used to
1934 resume the primary router position in the cell after the
1935 primary router comes back online. Affected files
1936 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1937 and silcd/server_util.[ch].
1939 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Sleep two (2) seconds after sending QUIT command to server.
1942 Affected file lib/silcclient/command.c.
1944 * Assure that if outgoing data buffer is pending do not force
1945 send any data. Affected file silcd/packet_send.c.
1947 * Assure that if outgoing data buffer is pending do not force
1948 send any data. Affected file lib/silcclient/client.c.
1950 * Implemented the backup router support when the primary router
1951 goes down. The servers and routers can now use the backup
1952 router as new primary router without loosing connectivity.
1954 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1957 in the server to indicate disabled entry. All data read
1958 from the connection will be ignored and no data is sent
1959 for entry that is disabled. Affected files are
1960 silcd/idlist.h, silcd/server.c.
1962 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Created SFTP client and server test programs in the
1965 lib/silcsftp/tests directory.
1967 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Implemented memory filesystem (virtual filesystem) for
1970 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1973 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Implemented the SFTP (SSH File Transfer Protocol) to the
1976 lib/silcsftp. It includes SFTP client and SFTP server
1979 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Moved lib/silccore/silcprotocol.[ch] to the
1982 lib/silcutil library.
1984 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1985 take variable argument list pointer as argument. Affected
1986 file lib/silcutil/silcbuffmt.[ch].
1988 * Added silc_buffer_set function that is used to set data
1989 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1990 Affected file lib/silcutil/silcbuffer.h.
1992 * Changed various routines in the core library to use the new
1993 silc_buffer_set instead of allocating new buffer only for
1996 * Added 64-bit value formatting and unformatting support to the
1997 silc_buffer_[un]format routines. Affected file is
1998 lib/silcutil/silcbuffmt.[ch].
2000 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2001 to includes/bitmove.h.
2003 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Fixed channel user mode saving in client library. Affected
2006 file lib/silcclient/command[_reply].c.
2008 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Defined the file transfer to the SILC Protocol. Added
2011 new packet type SILC_PACKET_FTP and defined File Transfer
2012 Payload. The mandatory file transfer protocol is SFTP
2013 (SSH File Transfer Protocol). Affected file in addition
2014 of the internet draft is lib/silccore/silcpacket.h.
2016 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2017 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2018 is used as part of backup router protocol when the primary
2019 router of the cell is back online and wishes to resume
2020 the position as primary router.
2022 * Redefined the MAC generation keys in the protocol. The
2023 same key is not used anymore in both direction. Both
2024 direction will now use different keys for sending and
2025 receiving. This fixes a potential security flaw. This
2026 change causes incompatibilities in the protocol.
2028 * Redefined also the MAC computation from the packet.
2029 An packet sequence number is now added to the MAC
2030 computation. This prevents possible replay attacks against
2031 the protocol. This change too causes incompatibilities
2034 Added `sequence' field to the SilcPacketContext to hold
2035 the current sequence number for the packet.
2037 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Added `created' field to the SilcIDListData in the file
2040 silcd/idlist.h to indicate the time when the entry was
2043 * Added `created' field to the SilcChannelEntry too. Affected
2044 file silcd/idlist.h.
2046 * Added `creation_time' aguments to all the announcement functions
2047 in the server. If it is provided then only the entries that
2048 was created after the provided time frame are actually
2049 announced. Affected file silcd/server.[ch].
2051 * The protocol says that the Channel ID's IP address must be
2052 based on the router's IP address. Added check for this in
2053 the silc_server_new_channel when processing incoming New Channel
2054 Payload. Affected file silcd/packet_receive.c.
2056 * Print out the correct version with --version in SILC client.
2057 Affected file irssi/src/silc/core/silc-core.c.
2059 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Fixed WHOWAS command to check for completnes of the client
2062 entry always, not just when the command is coming from client.
2063 Affected file silcd/command.c.
2065 * Added new function silc_server_packet_queue_purge to purge the
2066 outgoing data queue to the network. After the function returns
2067 it is guaranteed that the outgoing packet queue is empty.
2068 Affected file silcd/packet_send.[ch].
2070 * Purge the outgoing packet queue in the rekey protocol's final
2071 callback to assure that all rekey packets go to the network
2072 before quitting the protocol. Affected file silcd/server.c.
2074 * Added silc_client_packet_queue_parse as similar function as
2075 in server to the client library. The affected file is
2076 lib/silcclient/client.c.
2078 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Splitted silcd/server.c and created silcd/server_util.[ch]
2081 for utility functions.
2083 * Added new socket flag SILC_SF_DISABLED to indicate that the
2084 connection is open but nothing can be sent to or received from
2085 the connection. Affected file lib/silcutil/silsockconn.[ch].
2086 The checking for disabled socket is checked in the low level
2087 silc_socket_write and silc_socket_read functions.
2089 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Allow only nicknames and channel names that fits into the
2092 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2094 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * When processing JOIN command reply in server check that if
2097 the channel exists in our global list we'll move it the local
2098 list. Affected file silcd/command_reply.c.
2100 * Fixed the check whether client is joined on the channel already
2101 in JOIN command. Affected file lib/silcclient/command.c.
2103 * Fixed the JOIN command reply to check whether the channel
2104 already exists. Affected file lib/silcclient/command_reply.c.
2106 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Added silc_ske_status_string to map the SKE error numbers
2109 to readable strings. The affected files are
2110 lib/silcske/silcske[_status].[ch].
2112 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Do not show the private channels on the WHOIS channel list
2115 as it is not allowed by the protocol. The affected file is
2118 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Assure that the packet length digged from the actual packet
2121 is something sensible in the silc_packet_decrypt_rest_special
2122 in lib/silccrypt/silcpacket.c.
2124 * Free and NULL the allocated pointer in silc_hmac_alloc if
2125 the HMAC allocation fails. The affected file is
2126 lib/silccrypt/silchmac.c.
2128 * Print the selected security properties to the log files in
2129 the server. Affected file silcd/protocol.c.
2131 * Add SKE's reference counter even if calling the completion
2132 callback manually. Otherwise it goes negative, although it
2133 does not cause any problems. The affected file is
2134 lib/silcske/silcske.c.
2136 * Remove the client entry with short timeout after giving the
2137 KILL command. Affected file lib/silcclient/command.c.
2139 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2140 case all found clients are already disconnected (WHOWAS would
2141 found them) in the server. Affected file silcd/command.c.
2143 * Update the last_receive (time of last data received) to be
2144 updated only when received private or channel message so that
2145 the idle time showed in WHOIS makes more sense.
2147 * Added boolean field `valid' in to the SilcClientEntry in the
2148 client library to indicate whether the entry is valid or not.
2149 This fixes the nickname change bug on channel when changing
2150 the nickname to be same than the old (like nick to Nick) the
2151 nickname formatter doesn't set the new nick anymore to Nick@host.
2152 Affected file lib/silcclient/idlist.[ch].
2154 * Now actually fixed the nickname changing on disconnection.
2155 Added new function silc_change_nick to the Irssi SILC Client.
2156 Affected file irssi/src/silc/core/client_ops.c,
2157 irssi/src/silc/core/silc-nicklist.[ch].
2159 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Check that the public key exists in the GETKEY command before
2162 trying to encode it. Affected file silcd/command.c.
2164 * Print some notifications on received public keys with GETKEY
2165 command in the Irssi SILC Client. Affected files are
2166 irssi/src/fe-common/silc/module-formats.[ch],
2167 irssi/src/silc/core/client_ops.c.
2169 * Use IDENTIFY command to resolve the server information in the
2170 GETKEY command instead of INFO command. Affected file
2171 lib/silcclient/command.c.
2173 * All command reply functions in the client library now calls
2174 the pending command reply callbacks even if an error has
2175 occurred. The server has done this a long time and now it was
2176 time to move the client library to this as well. Now all
2177 errors can be delivered back to the pending command reply
2178 callbacks if necessary. Affected files are
2179 lib/silcclient/command[_reply].[ch].
2181 * Change the nickname on disconnection back to the username
2182 because in reconnect the server will enforce it to it anyway.
2183 Affected file irssi/src/silc/core/silc-servers.c.
2185 * Fixed a config file parsing bug in the Irssi SILC client.
2186 Affected file irssi/src/silc/core/clientconfig.c.
2188 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * When printing the channel mode on JOIN, verify that the
2191 channel key and channel's HMAC are valid. Affected file
2192 irssi/src/silc/core/client_ops.c.
2194 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2197 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2198 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2200 * Removed channel key rekey task deleting from the function
2201 silc_server_save_channel_key. Affected file silcd/server.c.
2202 Added explicit timeout task context instead that is used to
2203 delete the task if we are registering a new task before the
2204 new task has elapsed.
2206 * When channel key rekey occurs the client library now saves
2207 the old channel key for a short period of time (10 seconds) and
2208 is able to use it in case some is still sending channel
2209 messages encrypted with the old key after the rekey. Affected
2210 file lib/silcclient/[idlist.h|client_channel.c].
2212 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Added check to the silc_server_new_id_real to not accept
2215 new ID if it is the sender's own ID. Affected file is
2216 silcd/packet_receive.c.
2218 * Assure that we do not announce ourself or the one we've
2219 sending our announcements when we're router and are announcing
2220 servers to our primary router. Affected file silcd/server.c.
2222 * Fixed silc_server_command_identify_check_client to assemble
2223 correct WHOIS packet. It send corrupted WHOIS packet and
2224 caused problem with router to router connections. Affected
2225 file silcd/command.c.
2227 Fixed also silc_server_command_whois_check the same way
2228 as for the IDENTIFY command.
2230 * Added new SilcIDListStatus to the server in the SilcIDListData
2231 structure. The status now includes the current status of
2232 the entry (like registered, resolved etc.). Affected file
2233 silcd/idlist.[ch]. Defined a bunch of different status types
2234 as well. This replaced the old boolean registered field as well.
2236 Added resolve_cmd_ident field to the SilcClientEntry structure
2237 too so that if the entry is for example being resolved so
2238 another command may attach to the same pending command reply
2239 without requiring to resolve the same entry again. This concept
2240 should optimize the WHOIS and the IDENTIFY resolving under
2241 heavy load by taking away unnecessary resolving for entries
2242 that are being resolved already.
2244 Added support for adding multiple pending commands for one
2245 command idenfier. Affected file silcd/command[_reply].[ch].
2247 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2248 before deleting the data. Otherwise the hash table will have
2249 freed data in comparison functions. Affected file is
2250 silcd/command_reply.c.
2252 * Fixed silc_idlist_replace_client_id to add the new entry to
2253 the cache with NULL nickname. Otherwise there will be invalid
2254 memory as the nickname after the nickname is freed. Affected
2255 file silcd/packet_receive.c.
2257 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2258 saved into wrong slots because the previous number of entries
2259 was not taken into account. Affected file silcd/idlist.c.
2260 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2262 * If we are router and we receive JOIN notify to a channel that
2263 does not have any users then notified client is marked as the
2264 channel founder, as it is it. The affected file is
2265 silcd/packet_receive.c
2267 * Added to the extended hash table API's table_del_*ext functions
2268 the destructor as argument too, so that the caller can decide
2269 which destructor to use or whether to use destructor at all.
2270 Affected file lib/silcutil/silchashtable.[ch].
2272 * Fixed ID Cache purging. It actually deleted the entries from
2273 the hash table after the data was freed. The hash table ended
2274 up comparing freed memory. The affected file is
2275 lib/silccore/silcidcache.c.
2277 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * Fixed Irssi SILC client's KILL command's HELP syntax.
2281 * The USERS command now resolves the detailed user information
2282 if the userinfo field is missing. Affected file is
2283 lib/silcclient/command_reply.c.
2285 * Do not print error in silc_file_read if the read file does
2286 not exist. Just silently return NULL. Affected file is
2287 lib/silcutil/silcutil.c.
2289 * Fixed the silc_log_output to not wine about NULL filename
2290 and to not create some bogus " " filename. Affected file is
2291 lib/silcutil/silclog.c.
2293 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Fixed various printing bugs on the user interface in the
2296 Irssi SILC Client. Minor changes that were forgotten from
2299 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Fixed the configure.in.pre and the compilation and distribution
2302 environment to support the new autoconf 2.52. That version is
2303 now required to compile the CVS trunk.
2305 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2308 to generally parse user@fqdn format strings. Affected file
2309 lib/silcutil/silcutil.c.
2311 * Added nickname_format and nickname_force_format fields to the
2312 SilcClientParams structure. The first one defines the format
2313 for the nicknames that the library will enforce if the receives
2314 multiple same nicknames. The second one is boolean value and
2315 can be used to force the library to always enforce the format
2316 to the nicknames regardles whether there are multiple nicknames
2317 or not. This configurable formatting was employed to flexibly
2318 support accessing multiple nicknames from the user interface.
2319 The userinterface can now set the nicknames to what ever format
2320 they prefer. Affected file lib/silcclient/silcapi.h.
2322 Added function silc_client_nickname_format to the file
2323 lib/silcclient/idlist.c. It performs the nickname formatting.
2325 Added new field `hostname´ to the SilcClientEntry context.
2326 It holds the hostname of the client. Affected file is
2327 lib/silcclient/idlist.h.
2329 * Irssi SILC Client sets the nicknames in nick@hostn format.
2330 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2331 irssi/src/silc/core/silc-core.c.
2333 The WHOIS printing now also shows both the real nickname and
2334 the formatted nickname so that user knows how to access the
2335 user if there are multiple same nicknames cached. Affected
2336 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2337 printing formatting too to take the hostname now as a separate
2338 argument. The Affected file is
2339 irssi/src/fe-common/silc/modules-formats.[ch].
2341 * Changed the silc_client_get_clients_local to accept the formatted
2342 nickname as argument. It accepts the real nickname too but the
2343 formatted nickname can be used to find the true entry from
2344 multiple entries. Affected file lib/silcclient/silcapi.h and
2345 lib/silcclient/idlist.c.
2347 * Added nickname_format_parse field to the SilcClientParams.
2348 It is a callback function provided by the application to parse
2349 the nickname out of the formatted nickname string. The library
2350 calls it to get the nickname from the formatted string. Since
2351 the application generally knows better the format of the nickname
2352 string it parses it instead of the library, even though library
2353 encodes the formatted string. If the callback function is not
2354 provided then the library will use the string as is. The
2355 affected file is lib/silcclient/silcapi.h.
2357 * All the nickname strings passed to the client library in
2358 commands are now expected to be formatted nickname strings.
2359 If the command does not support the formatted nickname string
2360 it will assume that the sent string is the actual nickname.
2361 Affected file lib/silcclient/command.c.
2363 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added public key authentication support to OPER and SILCOPER
2366 commands in the client library. Affected file is
2367 lib/silcclient/command.c.
2369 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Changed the get_auth_methdod client operation to be asynchronous.
2372 It can be async if the application resolves the authentication
2373 method from the server during the negotiation. Added new
2374 SilcGetAuthMeth completion callback that the application will
2375 call after resolving the authentication method.
2377 Added function silc_client_request_authentication_method that
2378 the application can use to resolve the authentication method
2379 from the server. Added also SilcConnectionAuthRequest callback
2380 that the library will call after the server has replied. The
2381 application can call this function if it does not know the
2382 current authentication method.
2384 Affected files are lib/silcclient/client.c and
2385 lib/silcclient/silcapi.h.
2387 * The Irssi SILC client now automatically resolves the authentication
2388 method incase any configuration information is not present (and
2389 currently there never is). The affected file is
2390 irssi/src/silc/core/client_ops.c.
2392 * Fixed public key authentication from the client library.
2393 Affected file lib/silcclient/protocol.c. Changed also the
2394 protocol specification about the public key authentication in
2395 the connection authentication protocol. The actual data to be
2396 signed is now computed with a hash function before signing.
2398 * Fixed the public key authentication from the server as well.
2399 Affected file silcd/protocol.c.
2401 * Removed the mlock()'s from the memory allocation routines.
2402 Affected file lib/silcutil/silcmemory.c. The ./configure does
2403 not check anymore for the mlock(). Affected file is
2406 * Fixed USERS command in server to allow the execution of the
2407 command for private and secret channels if the client sending
2408 the command is on the channel. Affected file silcd/command.c.
2410 * Fixed silc_client_get_clients_local to return the clients
2411 count correctly. It could return wrong value. Affected file
2412 lib/silcclient/idlist.c.
2414 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2417 types. The assembler optimizations seemed not to like 64-bit
2418 data types. The assmebler optimizations thus are now enabled
2419 also for BSD systems as opposed to only enable them for Linux.
2421 * Do not check for threads at all on BSD systems. Affected
2422 file configure.in.pre.
2424 * Removed -n and -h options from the Irssi SILC Client since
2425 they are not used in silc.
2427 * Fixed the prime generation to assure that the first digit
2428 of the generated random number is not zero since our conversion
2429 routines does not like number strings that starts with zero
2430 digit. If zero digit is seen the random number is regenerated.
2431 This caused some corrupted RSA keys when the zero first digit
2432 was met. Affected file lib/silcmath/silcprimegen.c.
2434 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Fixed WIN32 configuration in the ./configure script.
2437 Fixed to include xti.h on environments that has it.
2438 Patches by Carsten Ilchmann and andrew.
2440 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Changed the silc_id_create_client_id to be collision
2443 resistant. It is now assured that there cannot be created
2444 two same client ID's. I suspect that some weird bugs in
2445 the server were actually caused by duplicate Client IDs.
2446 Affected file silcd/serverid.[ch]. A router receiving
2447 new ID now also assures and informs the sending server
2448 if the ID caused collision.
2450 * Changed the silc_id_create_channel_id to also assure that
2451 there are no collisions.
2453 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Statement about ignoring the Mutual Authentication flag when
2456 performing rekey with PFS was a bit misleading. It is ignored
2457 if it was set in the initial negotiation, it cannot be even
2458 set in the rekey. Fixed in the ke-auth draft. Started the
2459 new versions of the protocol drafts in the doc/.
2461 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Fixed a bug in silc_client_command_identify_save when saving
2464 new channel information. The channel name was no duplicated
2465 and caused crash on exit. Affected file is
2466 lib/silcclient/command_reply.c.
2468 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed the getkey command handling in the server. Send just
2471 empty OK reply to the sender if the key could not be fetched
2472 (but everything else was ok, like the key just was not available).
2473 Changed the public key parameter to optional in the protocol
2474 specs so that empty OK reply can be sent. Affected file
2477 Added a message to Irssi SILC client to tell to user if the
2478 server did not return a public key.
2480 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Fixed a channel key regeneration bug. It registered new
2483 timeout tasks exponentially until all system resources were
2484 used. Affected file silcd/server.c.
2486 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Added the SILC Document generator to the scripts/silcdoc.
2489 It can be used to generate the Toolkit Reference Manual out
2490 of the source tree. Internally it will also use the RoboDoc
2491 generator now imported in util/robodoc.
2493 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Added couple of return's in rekey protocol if error orccurred
2496 during the protocol. The execution must be terminated.
2497 Affected file silcd/protocol.c. Also, terminate the protocol
2498 always with timeout.
2500 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * The client's Client ID was created initally from the wrong
2503 nickname (it could have been in format nick@host) in the
2504 silc_server_new_client. Affected file silcd/packet_receive.c
2506 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Added some SILC_LOG_ERROR's to various error conditions
2509 if client could not be added to ID cache. Affected files
2510 silcd/packet_receive.c and silcd/server.c.
2512 * When client's sock->user_data is freed, NULL also the
2513 client->router and client->connection pointers. Added check
2514 for these pointers being NULL to various places around the
2515 code. Affected file silcd/server.c.
2517 * Added client->data.registered == TRUE checks to various
2518 places around the code to assure that unregistered client's
2519 are not handled when it is not allowed. Affected file
2522 * Added `bool registered' fields to all
2523 silc_idlist_[server|client]_get_* routines to indicate whether
2524 the fetched client needs to be registered or not. Affected
2525 file silcd/idlist.[ch].
2527 * Add your own entry as registered to the ID cache in the
2528 server. Affected file server.c.
2530 * Fixed a bug in silc_server_new_server. The SilcServer was
2531 set as the new server's context instead of SilcServerEntry.
2532 This naturally caused some weird bugs.
2534 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Do not delete the channel rekey task when adding it
2537 for in silc_server_create_channel_key.
2539 * Changed the silc_server_create_channel_key to return
2540 TRUE or FALSE to indicate the success of the channel key
2543 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Fixed MSVC++ project files and added missing files to
2546 Makefiles under win32/.
2548 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Do not add TCP_NODELAY flag if the operating system
2551 does not have it defined. Affected files are
2552 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2554 * Fixed buffer overflow from Irssi SILC Client. Affected
2555 file irssi/src/fe-common/core/themes.c.
2557 * Fixed double free in client library in the file
2558 lib/silcclient/client.c when disconnecting from server.
2560 * Applied double free patch from cras to Irssi SILC client.
2561 Affected files irssi/src/core/[modules/expandos].c
2563 * Fixed the disconnection handling to Irssi SILC Client.
2564 The application must call silc_client_close_connection
2565 in ops->connect client operation in case of failure of
2566 the connection. Affected file is
2567 irssi/src/silc/core/client_ops.c.
2569 * Do not set sock->protocol to NULL in the function
2570 silc_client_close_connection after executing the protocol's
2571 final callback since the sock might not be valid anymore.
2572 Affected file lib/silcclient/client.c.
2574 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Do not enable SILC_THREADS if the linking with libpthread
2577 did not happen. Affected file configure.in.pre.
2579 * Added notion to protocol specification that server must
2580 verify the sent authentication payload with CMODE when
2581 setting the channel founder key. Implemented it to the
2582 server. Affected file silcd/command.c.
2584 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Added _EXTRA_DIST SILC distribution variable to the
2587 distributions file. It is used to conditionally add extra
2588 files or directories to the specific distribution. Affected
2589 files ./prepare, Makefile.am.pre and distributions.
2591 Removed the `_' from the start of the distribution names.
2594 * Added README.WIN32 for instructions to compile the Toolkit
2597 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Fixed a double free in disconnection in the server. Affected
2600 file is silcd/server.c.
2602 * Fixed the lib/silcske/groups.c to work now also with GMP
2603 MP library. The string conversion did not work when using
2604 specific base and the base is indicated in the string as well.
2606 * Created win32/ directory which now includes MSVC++ specific
2607 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2608 It will appear only in the toolkit distribution
2610 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Changed the key material distribution function in case when
2613 the hash output is too short. The data is now concatenated
2614 a bit differently than it used to. Made the change to the
2615 SKE protocol specification.
2617 * Added better GMP detection to configure.in.pre. A patch
2620 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Fixed a minor bug in SKE that might cause some problem on
2623 some platforms. Affected file lib/silcske/silcske.c.
2625 * Added the cookie checking for initiator in the SKE. It checks
2626 that the responder returns the sent cookie unmodified. The
2627 affected file is lib/silcske/silcske.c. Added new SKE
2628 error type INVALID_COOKIE that can be sent during the
2629 negotiation. Fixed some memory leaks as well.
2631 * Added the "invalid cookie" error message to Irssi SILC client's
2634 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Added `task_max' field to the SilcClientParams to indicate
2637 the maximum tasks the scheduler can handle. If set to zero,
2638 default values are used. Affected file lib/silcclient/silcapi.h.
2640 * Fixed memory leaks in silc_client_close_connection. Affected
2641 file lib/silcclient/client.c.
2643 * Added silc_client_del_client_entry to client library to free
2644 all memory of given client entry. Affected file is
2645 lib/silcclient/idlist.[ch].
2647 * Added new functions silc_client_del_channel and
2648 silc_client_del_server to delete channel and server entries.
2649 Affected file lib/silcclient/[silcapi.h/idlist.c].
2651 * Removed silc_client_del_client_by_id from silcapi.h.
2653 * Fixed the INFO command to return the server's own info
2654 correctly when querying by Server ID. Affected file is
2657 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Removed the non-blocking settings in WIN32 code in the
2660 silc_sock_[read/write] and added SleepEx instead. Affected
2661 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2662 of input data is now checked with FIONREAD and ioctlsocket.
2664 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Call silc_schedule_task_del_by_context in the
2667 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2668 Affected file lib/silccore/silcprotocol.c.
2670 * Call silc_protocol_cancel for active protocols in the
2671 silc_server_close_connection if the funtion
2672 silc_server_free_sock_user_data has not been called.
2673 Affected file silcd/server.c.
2675 * Generic tasks cannot be deleted using the del_by_fd
2676 task deleting function since generic tasks does not match
2677 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2679 * Added a notion to SILCOPER help file that the SILCOPER works
2680 only on router server, not on normal server.
2682 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Added for WIN32 support for the new scheduler as well.
2685 Affected file lib/silcutil/win32/silcwin32schedule.c.
2687 * Fixed the SHA1 implementation to work on various platforms.
2689 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2692 API. It is part of the scheduler now. Everything else is
2693 as previously but some functions has changed their names.
2694 Checkout the lib/silcutil/silcschedule.h for the interface.
2695 Updated all applications to use the new interface. Affected
2696 files are lib/silcutil/silcschedule.[ch].
2698 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Found a bug in the SKE implementation. The HASH value,
2701 specified by the protocol, was not computed correctly. The
2702 public key of the responder was not added to the computation
2703 even though it is mandatory. Affected file lib/silcske/silcske.c.
2704 This unfortunately causes incompatibilities with older
2705 clients and servers.
2707 * Added WIN32 specific network init and uninit functions:
2708 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2709 the Winsock2. Affected file lib/silcutil/silcnet.h and
2710 lib/silcutil/win32/silcwin32net.c.
2712 * Set the socket always to nonblocking mode on WIN32 after
2713 reading data or writing data. Affected file is
2714 lib/silcutil/win32/silcwin32sockconn.c.
2716 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Fixed various compilation problems under WIN32. Affected
2719 files lib/silcutil/win32/silcwin32thread.c and
2720 lib/silcutil/win32/silcwin32schedule.c.
2722 * Removed all _internal.h #includes from public header
2723 files. Internal headers must never be included from
2726 Removed also the lib/silcske/payload_internal.h file.
2728 * All include files that may be needed (public and some others
2729 included by the public headers) by application developers are
2730 now copied to the ./includes directory. It does not copy any
2731 internal headers. Affected file Makefile.defines.pre and all
2732 Makefile.am's under lib/ and subdirs.
2734 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Do not change the ~/.silc directory's permissions automatically.
2737 Affected file irssi/src/silc/core/clientutil.c.
2739 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Do not cancel the protocol in silc_server_close_connection
2742 it might cause recursion. Now cancelled in the function
2743 silc_server_free_sock_user_data. Affected file silcd/server.c.
2745 * Fixed the silc_server_remove_clients_by_server to regenerate
2746 the channel keys correctly finally. Added also new function
2747 silc_server_remove_clients_channels to actually do it.
2748 Affected file silcd/server.c.
2750 * Fixed the silc_server_new_channel to not crash by giving
2751 wrong router to the new channel. Affected file is
2752 silcd/packet_receive.c.
2754 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2757 which is given as argument to the silc_client_alloc now.
2758 It can be used to configure the client and set various parameters
2759 that affect the function of the client.
2761 * The USERS command in server did not check whether the channel
2762 is private or secret. Affected file silcd/command.c.
2764 * Added new argument to the USERS command in protocol specification.
2765 The USERS command now can take the channel name as argument
2766 as well. Added support for this in client and server and
2767 updated the protocol specs.
2769 * Completed the GETKEY command in client. It can be now used
2770 to fetch also servers public key not only some clients.
2771 Affected files lib/silcclient/command[_reply].c.
2773 * Added silc_client_get_server to return server entry by the
2774 server name. Affected files lib/silcclient/silcapi.h and
2777 * Redefined the IDENTIFY command in protocol specification to be
2778 more generic. It now can be used to query information about
2779 any entity in the SILC Network, including clients, servers and
2780 channels. The query may be based either the entity's name
2781 or the ID. Added support for this in both client and server.
2783 Affected files silcd/command.c and lib/silcclient/command.c
2784 and command_reply.c.
2786 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2787 the _from_client and _from_server functions. Affected file
2790 * Added silc_client_get_channel_by_id_resolve to the file
2791 lib/silcclient/silcapi.h to resolve channel information by
2792 its ID. Added also silc_client_get_channel_by_id that
2793 does not resolve it from the server.
2795 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Added SilcServerEntry context into the client library
2798 to represent one server. The INFO command now allocates
2799 these to save the resolved server info. For now on the
2800 client library will also keep information about servers,
2801 connected and resolved with INFO.
2803 The INFO command now allocates the SilcServerEntry context
2804 and saves the server info there. The COMMAND_REPLY in
2805 the INFO now returns the parameters to application in
2806 same order as defined in the protocol specification.
2808 The entries are cached in the client->server_cache.
2810 * The INFO command is now issued after received the Client ID
2811 from the server. Affected file lib/silcclient/client.c.
2813 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2814 to the application as the mode changer might be server.
2815 It is guaranteed that NULL is not returned anymore to the
2816 application. Affected file lib/silcclient/client_notify.c.
2818 The ID Type is now also passed to the application so that
2819 it can check whether the returned entry is SilcClientEntry
2822 Added new function silc_client_get_server_by_id to return
2823 the server entry by ID. Affected files are the
2824 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2826 * Do not create the channel in the Irssi SILC Client when issuing
2827 the JOIN command but when received the sucessful JOIN command
2828 reply. Otherwise the channel might get created even though we
2829 could not join it. The Affected file is
2830 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2832 * Fixed a channel joining bug in router. The router must also
2833 check the channel modes, invite and ban lists etc. when serving
2834 the JOIN command sent by normal server. Affected file is
2835 silcd/command.c. The router now resolves the client's
2836 information from the server who sent the JOIN command if it
2837 does not know it, and processes the JOIN command only after
2840 * Changed the SilcCommandCb to take new argument; void *context2.
2841 Affected file lib/silccore/silccommand.h
2843 The second argument in the command callbacks in the server now
2844 includes the SilcServerCommandReplyContext if the command was
2845 called as pending command callback from the command reply.
2846 Otherwise it is NULL. When called as pending the status of the
2847 command reply will be checked and if it was erronous the
2848 error will be sent to the original sender of the command.
2849 This way the client always receives the error messages even
2850 though the server was actually the one who received the error
2851 when it resent the command to router, for example. Affected
2852 files silcd/command[_reply].[ch].
2854 * Fixed sending WHOWAS command's error message to client if
2855 the requested client could not be found. It was missing.
2858 * Changed the CMODE and CUMODE commands reply arguments in the
2859 protocol specification. The Channel ID is now sent in both
2860 of the commands to identify the channel. Implemented this
2861 new feature to the client and server. Affected files
2862 lib/silcclient/command_reply.c and silcd/command.c.
2864 * Made better checks for invite and ban lists in the JOIN
2865 command in server. Affected file silcd/command.c.
2867 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * The server now performs the incoming host IP/DNS lookup
2870 using the silc_socket_host_lookup and thus does not block
2871 the server anymore. Affected file silcd/server.c.
2873 * Completed the multi-thread support for SILC Scheduler in
2874 the lib/silcutil/silcschedule.c.
2876 * Fixed the configure.in.pre to detect the pthread correctly
2879 * Fixed a deadlock in silc_task_queue_wakeup in the file
2880 lib/silcutil/silctask.c.
2882 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * Added new function silc_schedule_wakeup that is used in
2885 multi-threaded environment to wakeup the main thread's
2886 schduler. It needs to be used when a thread adds a new task
2887 or removes a task from task queues. After waking up, the
2888 scheduler will detect the task queue changes. If threads
2889 support is not compiled in this function has no effect.
2890 Implemented the wakeup mechanism to both Unix and WIN32
2891 systems. Affected files are lib/silcutil/silcschedule.[ch],
2892 lib/silcutil/unix/silcunixschedule.c and the
2893 lib/silcutil/win32/silcwin32schedule.c.
2895 * Added new function silc_task_queue_wakeup to wakeup the
2896 scheduler by the specified task queue. Affected file
2897 lib/silcutil/silctask.[ch].
2899 * The silc_socket_host_lookup_start now wakes up the scheduler
2900 after adding the timeout task. Affected file is
2901 lib/silcutil/silcsockconn.c.
2903 * The silc_socket_host_lookup is synchronous now if the threads
2904 support is not compiled in. However, the callback is still
2905 called asyncronously through the scheduler, anyway. Affected
2906 file lib/silcutil/silcsockconn.c.
2908 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Added new function silc_socket_host_lookup to perform
2911 asynchronous IP and FQDN lookups for the socket connection.
2912 Affected files lib/silcutil/silcsockconn.[ch].
2914 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2917 that may or may not compile the mutex support in.
2919 Changed the silc_mutex_alloc interface. It allocates the
2920 mutex now to the sent pointer and returns TRUE or FALSE.
2922 Affected file lib/silcutil/silcmutex.h.
2924 * Wrote the SILC Task Queue interface to support multi-threads.
2925 Affected file lib/silcutil/silctask.[ch].
2927 * Wrote the SILC Scheduler to support multi-threads. Affected
2928 file lib/silcutil/silcschedule.c.
2930 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2932 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2933 in lib/silcutil/win32/.
2935 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Defined SILC Mutex API and SILC Thread API and implemented
2938 them for Unix. Affected files are
2939 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2940 lib/silcutil/unix/silcunixmutex.c and
2941 lib/silcutil/unix/silcunixthread.c.
2943 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Fixed the silc_server_remove_clients_by_server's channel
2946 key re-generation. The hash table handling was incorrect
2947 and would not work with many channels. Affected file is
2950 * Fixed some memory leaks around the server code.
2952 * Rewrote the silc_server_get_users_on_channel to support IPv6
2953 based Client ID's. Affected file silcd/server.c.
2955 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2956 specification. However, a separate document must be written
2957 to define the detailed signing procedure and the payload
2958 associated with the flag. Defined the flag to the
2959 lib/silccore/silcchannel.h as well.
2961 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Changed the dynamic tables to static size tables in the
2964 lib/silccrypt/silchmac.c.
2966 * Removed GCC dependencies from the code. A patch by cras.
2968 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Do not show the error "Error receiving packet bla bla"
2971 in server if it really was not an error (-2 means that reading
2972 is pending). Affected file silcd/server.c.
2974 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Fixed a possible crash in silc_server_remove_clients_by_server
2977 in silcd/server.c. Fixed there also some memory leaks.
2979 * Fixed the silc_idlist_replace_client_id. It could replace
2980 wrong key in the hash table. Affected file silcd/idlist.c.
2982 * Do not check whether there are global users on the channel
2983 if the channel->global_users is FALSE. Affected functions
2984 silc_server_remove_from_one_channel and
2985 silc_server_remove_from_channels in silcd/server.c. Also,
2986 do not check if the removed client is local as we can be
2987 sure that global client was not removed from the channel
2988 and checking for global users is not needed.
2990 * The silc_server_remove_clients_by_server now re-generates
2991 the channel keys correctly for those channels that had
2992 clients removed from them. Affected file silcd/server.c.
2994 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Found the reason of random crashes in the server. We weren't
2997 ignoring the SIGPIPE signal (which can be sent in write())
2998 and it crashed the server. Affected file silcd/silcd.c.
3000 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Assure that sock->user_data is not NULL in the function
3003 silc_server_packet_send in silcd/packet_send.c.
3005 * Disconnect the remote connection if it could not be added
3006 to any ID lists in the server. The affected file is
3009 * Check in silc_server_packet_send[_real/dest] that the
3010 socket is not disconnecting and ignore the data if it is.
3011 Affected file silcd/packet_send.c.
3013 * Define inline to __inline on native WIN32 compilation.
3014 Affected file includes/silcwin32.h.
3016 * Added some explicit type casts for inline code since MSVC
3017 require them. Affected files lib/silcutil/silcbuffer.h,
3018 lib/trq/silcdlist.h and lib/trq/silclist.h.
3020 * Print warning in log files from now on if the packet
3021 decryption fails. Affected file silcd/server.c.
3023 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Changed the `say' client operation's interface to accept
3026 new `type' argument to indicate the type of the message sent
3027 by the library. The application may filter the library's
3028 messages according the type. The affected file is the
3029 lib/silcclient/silcapi.h.
3031 * Added two new functions to lib/silcclient/silcapi.h:
3032 silc_client_del_client and silc_client_del_client_by_id.
3033 Affected file lib/silcclient/idlist.c.
3035 * Moved the clientincludes.h from includes/ to silc/ and
3036 serverincludes.h from includes/ to silcd/.
3038 * The modes for the CMODE and CUMODE are now passed as
3039 uint32 for application with COMMAND_REPLY. The affected
3040 file is lib/silcclient/command_reply.c.
3042 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3044 * /WHOIS without arguments shows client's own information.
3045 Affected file lib/silcclient/command.c.
3047 * Changed PING to not accept any arguments. The specs
3048 says that client can ping only the connected server so
3049 requiring an argument is not needed. Affected file is
3050 lib/silcclient/command.c.
3052 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Fixed a fatal bug in private message sending and reception
3055 encryption and decryption when using private message keys.
3056 The implementation was incorrect and did not follow the
3057 specification. It causd that some of the message were
3058 lost since it did not use the sending and receiving keys
3059 as the protocol suggests. This has been fixed and will cause
3060 incompatibilities with older clients when sending private
3061 message encrypted with private message keys. Affected files
3062 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3063 and various other in Irssi SILC Client.
3065 Added `responder' boolean argument to the functions
3066 silc_client_add_private_message_key[_ske] to indicate when
3067 the key is added as responder or initiator of the key
3070 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Removed the silc_ske_check_version function and created
3073 a SilcSKECheckVersion callback. Added also a function
3074 silc_ske_set_callbacks that is now used to set all SKE
3075 callbacks. The callback functions are not given to
3076 the SKE functions anymore, but this function is used to
3079 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3081 * Added `silc_version' argument to the silc_client_alloc
3082 to define the version of the application for the library.
3083 The library will use the version string to compare it
3084 against the remote host's (usually a server) version
3085 string. Affected file lib/silcclient/silcapi.h
3087 * Added the KE protocol context to Key Agreement context
3088 in client library so that we can abort the SKE if it
3089 is in process when we get timeout. Affected file is
3090 lib/silcclient/client_keyagr.c.
3092 * Do not resolve the client ID forever if it returns in the
3093 first time that such client does not exist. This was done
3094 for example with private message. Affected file is
3095 lib/silcclient/client_prvmsg.c.
3097 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Do not add regex.h for WIN32. The affected file
3100 includes/silcincludes.h.
3102 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3103 not work yet 100%. It generates the DLL's automatically
3104 when compiling with --with-win32 under cygwin.
3106 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * lib/contrib/regex.c is not compiled on WIN32.
3110 * Added silc_net_get_socket_opt function to the
3111 lib/silcutil/silcnet.h.
3113 * Added includes/silcwin32.h for WIN32 specific includes
3116 * Do not use ptime structure or any of the posix process
3117 functions on WIN32 in lib/silccrypt/silrng.c.
3119 * Added silc_gettimeofday to provide generic function
3120 for struct timeval on all platforms. Added the function
3121 to lib/silcutil/silcutil.h.
3123 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3126 library as they clearly belong there. As a plus side we
3127 can make the actual socket connection routines platform
3130 Added also new generic function silc_socket_read and
3131 silc_socket_write (that used to be silc_packet_[read/write].
3132 The implementation of these are platform specific.
3134 * Added WIN32 specific routines of silc_socket_[read/write]
3135 to lib/silcutil/win32/silcwin32sockconn.c.
3137 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Added preliminary support for native WIN32 compilation under
3140 cygwin (using the -mno-cygwin option for GCC) to the
3141 ./configure.in.pre. The --with-win32 now prepares the
3142 compilation for native WIN32.
3144 * Rewrote the SILC Scheduler interface in the file
3145 lib/silcutil/silcschedule.h. The scheduler is now context
3146 based and does not have anymore any global static scheduler.
3147 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3148 and created lib/silcutil/win32 directory for WIN32 based
3151 * Added Unix specific network routines to the
3152 lib/silcutil/unix/silcunixnet.c and the old
3153 lib/silcutil/silcnet.c includes now only generic routines.
3155 Added WIN32 specific network routines to the
3156 lib/silcutil/win32/silcwin32net.c.
3158 * Added Unix specific utility functions from the
3159 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3161 * Added WIN32 SILC Scheduler to the file
3162 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3165 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Do not handle JOIN notify in the server if the target client
3168 is not registered (idata->registered == FALSE). The affected
3169 file is silcd/packet_receive.c.
3171 * Update the nickrec->founder in event_cumode in the Irssi SILC
3172 client. Affected file irssi/src/silc/core/silc-channels.c.
3174 * Fixed the CUMODE_CHANGE notify handling in the server when
3175 server and router are announcing their clients on channels.
3176 Now the mode changes are saved and notified correctly. The
3177 affected file is /silcd/packet_receive.c.
3179 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3180 They really did not replace the cache entry in the ID Cache.
3181 Now they do that. Affected file silcd/idlist.c.
3183 * Fixed the KICK notify handling in the Irssi SILC client to
3184 update the channel records so that the kicked client does not
3185 appear to be on the channel. The affected file is
3186 irssi/src/silc/core/silc-channels.c.
3188 * Always update the conn->current_channel when executing command
3189 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3191 * Fixed the KILL notify handling in Irssi SILC client to remove
3192 the killed client on all channels.
3194 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Fixed the silc_parse_command_line to remove extra spaces
3197 from the start and end of the arguments. Affected file is
3198 lib/silcutil/silcutil.c.
3200 * Cancel and free any active protocol in the function
3201 silc_server_close_connection. Affected file silcd/server.c.
3203 * Cancel and free any active protocol in the function
3204 silc_client_close_connction. Affected file is
3205 lib/silcclient/client.c.
3207 * Do not execute the KILL command for clients that are in
3208 history (ie. they are not in the network). Affected file is
3211 * Fixed KILL notify handling, client does not crash anymore.
3212 Affected file irssi/src/silc/core/silc-channels.c.
3214 * Reduced the default packet buffer size from 2048 to 1024 in
3215 lib/silccore/silcpacket.c.
3217 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3218 counter to the SKE context that is incresed when the SKE library
3219 performs async operation outside the library. If the outside
3220 process frees the SKE context and FREED status will be set
3221 and the library will detect after the sync operation that the
3222 libary is freed. The affected files are
3223 lib/silcske/silcske[_status].[ch].
3225 * Resolve the client entry information in the function
3226 silc_client_channel_message to assure that NULL pointer is not
3227 passed as client entry to the application. */
3229 * Fixed the task timeout calculation to assure that there is
3230 never negative timeouts. The affected file is
3231 lib/silcutil/silcschedule.c.
3233 * Fixed the channel user mode notification sending in server.
3234 It was sent point-to-point to the router (or to server by router)
3235 but it needs to be destined to a channel. The routines now
3236 supports sending the channel user mode notifys to the channels
3237 when announcing clients and channels. Affected files are
3238 silcd/server.c and silcd/packet_receive.c.
3240 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3241 It did not actually replace the old channel entry in the cache.
3242 Affected file lib/silcclient/client_notify.c.
3244 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Fixed a possible crash in silc_packet_send_prepare. It now
3247 assures always that there is enough space in the buffer and
3248 at the tail area of the buffer (for MAC).
3250 Fixed the inbound buffer reallocation in silc_packet_read.
3251 It was old code and did not handle the reallocation correctly.
3254 The affected file is lib/silccore/silcpacket.c.
3256 * Fixed buffer overflow in silc_parse_nickname in the file
3257 lib/silcutil/silcutil.c.
3259 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * make install generates new server keys only if there is not
3264 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3267 Added check that if the NOREPLY is set then we will not send
3268 the away message. This avoids infinite loop of away messages
3269 if both clients are away. The affected file is
3270 lib/silcclient/client_prvmsg.c.
3272 * Fixed client crash if /NICK was given without arguments.
3273 Affected file lib/silcclient/command.c.
3275 * Server does not send the invite list in INVITE command back
3276 to the client if the list was not altered. Added this notion
3277 to the protocol spec as well. Affected file silcd/command.c.
3279 Fixed possible crash in INVITE command by checking the
3280 value of silc_server_get_client_route command.
3282 * Fixed the INVITE notify type handling. The arguments are now
3283 taken in correct order and client does not crash. The affected
3284 file is irssi/src/silc/core/silc-channels.c.
3286 Removed the "Inviting xxx to channel" message from the
3287 client library away and let the application handle it.
3288 Affected file lib/silcclient/command.c. Added that message
3289 to Irssi SILC client's message formats.
3291 * Fixed CMODE command crash in client. It now checks the
3292 amount of arguments correctly and does not crash. The affected
3293 file is lib/silcclient/command.c.
3295 * Do not create new channel automatically in silc_channels_join
3296 but check whether the channel by that name already exists.
3297 Affected file irssi/silc/core/silc-channels.c.
3299 * Do not send the SERVER_SIGNOFF to router if the disconnected
3300 entity was the router. Affected file silcd/server.c.
3302 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3303 SILC client as it was missing from there.
3305 Added the handling of the KICK notify to the Irssi SILC client
3306 as it was missing. Added "you have been kicked" message to
3307 Irssi SILC client's message modules formats.
3309 Added the handing of the KILL notify to the Irssi SILC client
3310 as it was missing. Added the kill message module formats
3313 The affected file is irssi/src/silc/core/silc-channels.c.
3315 * The router did not save the channel mode the server announced.
3316 Affected file silcd/packet_receive.c.
3318 * Fixed a possible crash in INFO command in server. If the
3319 server did not provide the server info it crashed. Affected
3320 file silcd/command.c.
3322 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Fixed the GETKEY command in the server to check also the
3325 global list. Otherwise the GETKEY would not work correctly
3326 in normal SILC server. Affected file silcd/command.c.
3328 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Fixed GETKEY crash, it crashed if the command did not succseed.
3332 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3335 is now real and not just an macro interface to GMP.
3337 Removed the entire GMP from the source tree and imported new
3338 NSS MPI library instead. Reason for removing GMP is that it is
3339 extremely large and compiles extremely slow. The NSS MPI
3340 is only a few files and compiles in less than 10 seconds.
3341 The speed is also about the same as GMP. The MPI is imported
3342 to lib/silcmath/mpi.
3344 If the system has GMP installed we will still use the GMP.
3345 If it is not then the NSS MPI will be compiled.
3347 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Merged a long nickname (127 characters long) crash bugfix from
3350 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3352 * Merged a freed memory reference bugfix from Irssi CVS tree.
3353 Affected file irssi/src/core/commands.c.
3355 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Added the server's public key sving and verification to the
3358 server when performing the SKE. This was missing and the
3359 remote server's (or router's) public key was accepted without
3360 checking whether we have it previously or trust it at all.
3361 Affected file silcd/protocol.c.
3363 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Check in the silc_server_timeout_remote if protocol is active
3366 and make sure that the protocol's final callback is called so
3367 that all memory if freed. Affected file silcd/server.c.
3369 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * silc_server_whois_send_reply crashed the server if the nickname
3372 was 127 characters long. Affected file silcd/command.c.
3374 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Added sanity check to the silc_server_new_client. If the hostname
3377 is provided inside username then check that the provided hostname
3378 really is the same as the resolved one. If the hostname was not
3379 resolved then check it from the public key. Affected file is
3380 silcd/packet_receive.c.
3382 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3383 if the server disconnected us and the connection is not valid
3384 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3386 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3387 the library to the lib/silcutil/silcutil.[ch].
3389 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Close log file after open. Affected file
3392 lib/silcutil/silclog.c.
3394 * Check whether sock == NULL in silc_client_send_packet and return
3395 if it is. Affected file lib/silcclient/silcclient.c.
3397 * Check rec->entry == NULL in the Irssi SILC Client before
3398 sending the channel message. Affecte file is
3399 irssi/src/silc/core/silc-servers.c.
3401 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Merged a splitted window bugfix from Irssi CVS tree. The
3404 affected file is irssi/src/fe-text/textbuffer-view.c.
3406 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3407 It did not print nickname.
3409 * Improved the distributions system a bit.
3411 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3414 irssi/src/fe-text/gui-window.c.
3416 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3417 to in-active server. The affected file is
3418 irssi/src/silc/core/client_ops.c.
3420 * Resolve the client in USERS command reply if the entry does
3421 not have username resolved. The affected file is
3422 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3423 command to WHOIS command to really resolve stuff. The USERS
3424 is not used any more in any critical section so WHOIS can
3425 be used even though it might be slower than IDENTIFY.
3427 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3430 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Changed the protocol API a bit more consistent in the
3433 lib/silccore/silcprotocol.[ch].
3435 * Changed the following headers to ROBODoc format:
3437 lib/silccore/silcpayload.h
3438 lib/silccore/silcprotocol.h
3439 lib/silccore/silcsockconn.h
3441 All core library headers are now formatted.
3443 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Fixed a bug in Irssi SILC client; do not show that you are
3446 server/router operator if you really are not. Affected file is
3447 irssi/src/silc/core/client_ops.c.
3449 * Renamed silc_command_free_payload to silc_command_payload_free.
3450 Affected file lib/silccore/silccommand.h
3452 * Added silcmath.h to include the prototoypes of various routines
3453 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3456 * Changed the following headers to ROBODoc format:
3458 lib/silccore/silcchannel.h
3459 lib/silccore/silccommand.h
3460 lib/silccore/silcid.h
3461 lib/silccore/silcidcache.h
3462 lib/silccore/silcmode.h
3463 lib/silccore/silcnotify.h
3464 lib/silccore/silcpacket.h
3465 lib/silcmath/silcmath.h
3467 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Added checking to the server code not to start the server if
3470 ciphers and stuff are not configured properly. Affected files
3471 silcd/serverconfig.[h] and silcd/server.c.
3473 * Changed the layout of the header files of the public interfaces
3474 in the SILC libraries. The new layout supports ROBODoc
3475 documentation tool (and some others) so that it is easy to create
3476 a library reference manual. All the other headers and source
3477 code must still follow the CodingStyle document. Also source
3478 code must not include these ROBODoc stuffs, only the headers.
3479 Furthermore, all public interface headers must now be named
3480 by using `silc' prefix, example: silcapi.h, silccipher.h.
3481 Some files were renamed due to this. All the other headers
3482 must not be used as public interfaces. I will update the
3483 CodingStyle document later. Changed following headers, so far:
3485 lib/silcclient/silcapi.h
3486 lib/silccore/silcauth.h
3487 lib/silccore/silcprivate.h
3488 lib/silccrypt/silcdh.h
3490 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Removed silc_client_packet_send_flush from the client library
3495 as it is not needed. Affected file lib/silcclient/client.[ch].
3497 * Added printing of message of unresolved authentication method
3498 to the Irssi SILC client. Added it to the module formats.
3499 Removed the same message from the client library.
3501 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added new distribution feature, DISTLABEL. Every distribution
3504 can define own preprocessor label that can be used in the
3505 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3506 file distributions, acconfig.h.pre and prepare.
3508 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added Makefile.defines_int to include the actual definitions
3511 for Makefile.defines.in. Tested the new distribution system,
3512 created distributions and tested installation.
3514 * Added AWAY message printing to the Irssi SILC client. Added
3515 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3517 * Added SCONNECT command to call the SILC's CONNECT command.
3518 Cannot use CONNECT directly since Irssi uses that internally.
3519 Affected file irssi/src/silc/core/silc-servers.c.
3521 Added ACTION local command. It is same as ME command but takes
3522 the channel as mandatory argument.
3524 Rewrote some of the Irssi's help files to suite for SILC
3527 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Added Makefile.defines[.in] that should for now on be included
3530 in all Makefile.am file in the source tree. That file includes
3531 all common compilation definitions for SILC source tree.
3533 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Minor changes to the ./prepare script to change the package
3536 name according the distribution name to the configure.in.
3538 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Created new distribution system. Added file `distributions'
3541 that defines all the distributions that can be created out of
3542 the SILC source tree. The ./prepare script now reads that
3543 file to determine how to prepare the distributions. The
3544 first argument to the ./prepare is the name of the distribution
3545 and second is the version of the distribution. If given
3546 without arguments it creates the default (toolkit) distribution
3547 with the default version (defined in ./prepare).
3549 All Makefile.am files that are subject to the distributions
3550 are now named as Makefile.am.pre. These are ./Makefile.am
3551 and lib/Makefile.am. Others may be changed later.
3553 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added invite list, ban list, some key management and connection
3556 error message printing to module formats in the Irssi SILC client.
3558 * Added new silc_client_set_away_message to set the away message
3559 that is back to the person who sent private message. The
3560 affected file lib/silcclient/silcapi.h and the
3561 lib/silcclient/client_prvmsg.c.
3563 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Fixed the private message sending in the Irssi SILC client,
3566 added local command KEY to the Irssi SILC client.
3568 Added key management and key agreement message formats to the
3569 irssi/src/fe-common/silc/module-formats.[ch].
3571 Added USERS (alias WHO) printing, server/router operator
3572 indication and LIST command printing to the module formats.
3574 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Fixed channel joining notify handling, cumode notify handling
3577 from Irssi SILC client.
3579 * Added SILC specific module-formats to the Irssi SILC client so
3580 that SILC specific message hilighting, colors etc is possible.
3581 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3583 Added channel mode, channel user mode, actions, notices,
3584 whois and whowas printing to the the module-formats.c.
3586 * Fixed a bug in channel deletion in the server. The channel
3587 is not left to the cache even if the channel founder auth mode
3588 is set when there are no users anymore on the channel. Affected
3589 file silcd/server.c.
3591 * The silc_net_localhost now resolves the entire hostname including
3592 the domain name. Affected file lib/silcutil/silcnet.c.
3594 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Changed the ask_passphrase client operation to be ascynchronous.
3597 It has now a completion callback and a context that the
3598 application must call after it has got the passphrase from
3599 the user. Affected files lib/silcclient/silcapi.h,
3600 lib/silcclient/protocol.c, lib/silcclient/command.c and
3603 Added SilcAskPassphrase callback that the application calls
3604 to deliver the passphrase to the library.
3606 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3607 The public key verification and especially a certificate
3608 verification is asynchronous procedure.
3610 Added new SILC_SKE_STATUS_PENDING status to indicate the
3611 request is pending and a callback will be called to finalize
3614 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3615 indicate that remote end did not send its public key (or
3616 certificate), even though we require it. Added check for this
3617 condition in the SKE. This was a security bug, now fixed.
3619 Defined new SilcSKEVerifyCbCompletion callback that is called
3620 when the verification process is completed.
3622 The affected files lib/silcske/silcske_status.h and
3623 lib/silcske/silcske.[ch].
3625 * Changed the verify_public_key client operation to be async
3626 as well. Defined SilcVerifyPublicKey callback that is used to
3627 indicate the success of the public key verification process.
3629 Changed the server and client to use the new async client
3632 * Changed the Irssi SILC client's internal scheduler to be called
3633 twice as many times as it used to be. As a result the client
3634 should be a bit faster now. Affected file is
3635 irssi/src/silc/core/silc-core.c.
3637 * Added support to Irssi SILC client of asynchronous public key
3638 verification and passphrase inquiry. Affected file is
3639 irssi/src/silc/core/silc-core.c.
3641 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Do not say "You have left channel %s" in client library.
3644 Moved it to the application. Affected files are
3645 lib/silcclient/command.c and silc/client_ops.c.
3647 * Fixed silc_client_get_clients. Command context was not
3648 duplicated and was freed memory in the callback. Affected
3649 file lib/silcclient/idlist.c.
3651 * Do not say "you are now talking..." on JOIN command in the
3652 client library. The appliation must handle it.
3654 * Do not say ".. changed topic to" in command reply in the
3655 client libary. The application must handle it.
3657 * Fixed TOPIC command sending in the client library.
3659 * Fixed a memory leak in silc_client_command_free in the file
3660 lib/silcclient/command.c.
3662 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Imported a modified version of Irssi client to the source tree.
3665 The Irssi will be used to create a new client called
3666 Irssi SILC. Imported to irssi/.
3668 Added silc_core_init_finish function to the Irssi. Affected
3669 file irssi/configure.in.
3671 A lot changes in the Makefile.ams around the irssi tree.
3673 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Do not rehash if the new size is same as the old size of the
3676 hash table, in the silc_hash_table_rehash*. The affected file
3677 lib/silcutil/silchashtable.c.
3679 * Replaced hash_table_del_by_context calls from the server
3680 (when channel->user_list and client->channels) to the
3681 hash_table_del as it is sufficient and faster.
3683 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Added silc_hash_table_list, silc_hash_table_get and the
3686 SilcHashTableList structure to provide an alternative way to
3687 traverse the hash table. The affected files are
3688 lib/silcutil/silchashtable.[ch].
3690 * Changed the server's idlist routines to use the hash table
3691 routines to optimize the code.
3693 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Replaced the client entry's `channel' list and channel entry's
3696 `user_list' list to hash tables for optimized lookup. Changed
3697 the code to use the hash table interface around the code.
3698 Affected file lib/silcd/idlist.[ch].
3700 * Added `auto_rehash' boolean argument to the function
3701 silc_hash_table_alloc to indicate whether the hash table should
3702 auto-rehash when it thinks is appropriate time. It will
3703 increase the hash table size if the there is twice as much
3704 entries in the table than the size of the table, and will
3705 decrease the size if there are twice as less entries than
3706 the size of the table.
3708 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3712 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * silc_idcache_purge_by_context deletes the entry now by context
3715 as it is supposed to do. Affected file lib/silccore/idcache.c.
3717 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3718 client is not anymore valid (WHOWAS givens the info) and not
3719 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3721 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Removed the `data' and `data_len' arguments from the ID Cache
3724 interfaces and added `name' argument. ID Cache does not handle
3725 anymore the binary data only a names associated with given ID.
3727 * When hashing a Client ID with silc_hash_id the entire ID is
3728 not hashed anymore, instead only the hash of the Client ID is
3729 hashed. This way we can access the Client ID from the cache
3730 with Client ID but with the hash of the ID (which is a hash of
3731 the nickname) as well without any difference in performance.
3733 Added also silc_idcache_find_by_id_one_ext to do one on one
3734 searching when we have the actual ID. Added also function
3735 silc_hash_client_id_compare. The affected files are
3736 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3738 * When hashing the name associated with a ID it is always done
3739 in lowercase. This way we can access the cache without worrying
3740 about case-sensitivity, even though, for example nicknames are
3743 * Fixed a bug in server with channel message sending. It put
3744 wrong ID type as destination ID. The affected file
3745 silcd/packet_send.c.
3747 * silc_idcache_del_by_context now deletes from all hash tables
3748 by context. Affected file lib/silccore/idcache.c.
3750 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Changed the client library to use the new ID Cache interface.
3753 Changes around the source tree.
3755 * Added silc_hash_table_rehash_ext to rehash with specific
3756 hash function. Affected file lib/silcutil/silchashtable.[ch].
3758 * Added silc_hash_string_compare to compare two strings in the
3759 hash table. Affected file lib/silcutil/silcutil.[ch].
3761 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Added new function silc_idcache_del_by_context into the
3764 lib/silccore/idcache.[ch].
3766 * Changed the server's ID list routines to use the new ID Cache
3767 interface. Changes around the source tree.
3769 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Added silc_hash_table_del[_by_context]_ext functions in to the
3772 lib/silcutil/silchashtable.[ch].
3774 Removed silc_hash_table_find_all* routines and added new
3775 silc_hash_table_find_foreach to replace them.
3777 Added silc_hash_table_replace_ext function as extended
3778 replacing function. Separated the simple hash table interface
3779 from the extended hash table interface in the file
3780 lib/silcutil/silchashtable.h.
3782 * Fixed minor bugs and changed it to use some of the new
3783 hash table functions in lib/silccore/idcache.c
3785 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Added new function silc_hash_table_find_all to return all keys
3788 in the hash table by the specified key. As the hash table is
3789 collision resistant it also makes it possible to have several
3790 duplicate keys in the hash table. This function may be used to
3791 find all of the keys from the hash.
3793 Added user_context arguments to the SilcHashFunction,
3794 SilcHashCompare and SilcHashDestructor to deliver user specified
3797 Added new fuctions silc_hash_table_find[_all]_ext to do
3798 extended lookup with specified hash and compare functions and
3799 specified user contexts.
3801 Added new function silc_hash_table_add_ext to add the key
3802 with specified hash function and user context.
3804 Added new function silc_hash_table_foreach to traverse all
3805 entrys in the hash table. Added SilcHashForeach callback
3808 Added new function silc_hash_table_del_by_context to delete
3809 the entry only if the context associated with the key matches.
3811 Affected files are lib/silcutil/silchashtable.[ch].
3813 * Removed silc_hash_[server/client/channel]_id and added just
3814 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3815 silc_hash_id_compare to compare two ID's using as the hash table
3816 comparison function. Added also silc_hash_data to hash
3817 binary data and silc_hash_data_compare to compare it.
3819 * Removed silc_idlist_find_client_by_hash as it is not needed
3820 anymore. Affected file silcd/idlist.[ch].
3822 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3823 to use internally the SilcHashTable. The new ID Cache is a lot
3824 faster than the old one. Some of the ID Cache interface was also
3825 rewritten and obsolete and stupid functions were removed.
3827 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Added entry_count field to the SilcHashTable to keep the number
3830 of the entries in the table. Implemented the function
3831 silc_hash_table_rehash. Added new function
3832 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3834 Fixed a minor bug in silc_hash_table_free.
3836 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3837 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3838 into the lib/silcutil/silcutil.[ch].
3840 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Implemented a collision resistant hash table into the
3843 lib/silcutil/silchashtable[ch]. See the header and the source
3844 for the SilcHashTable API.
3846 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Merged dotconf version 1.0.2 into lib/dotconf.
3850 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Do not compile anything in lib/silcsim/* if the SIM support
3853 is not enabled. The tree should now compile without problems
3856 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Compiled the SILC under cygwin. Compiled and tested briefly
3859 without problems. More tests needed. The SIMs didn't compile
3862 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3864 * Fixed possible crash in silc_get_username in the
3865 lib/silcutil/silcutil.c.
3867 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Fixed a va_arg in silc/client_ops.c.
3871 * Oops, RC5 routines were named AES and caused some problems
3872 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3874 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added new SilcIDIP structure into the lib/silccore/id.h and
3877 replaced the old `ip' fields from all SILC ID's to that type.
3878 This is a step towards IPv6 support.
3880 The silc_id_get_len takes now the ID as an extra argument.
3881 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3882 both IPv4 and IPv6 based ID's.
3884 The affected files are lib/silccore/id.[ch] and other files
3885 around the tree using these routines.
3887 * Removed the ID length arguments in server from various
3888 silc_server_send_notify_* routines -> they are not needed
3891 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Fixed memory leak in silc_encode_pem_file in the file
3894 lib/silcutil/silcutil.c.
3896 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Check minor version as well in the SKE. Affected files are
3899 silcd/protocol.c and lib/silcclient/protocol.c.
3901 * Added --identifier option to the server so that an identifier
3902 can be when creating the public key for the server. Affected
3903 file is silcd/silcd.c.
3905 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3906 lib/silccrypt/silcpkcs.c.
3908 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Register default ciphers and stuff when using -C option with
3911 the server. Affected file sildc/silcd.c.
3913 * Put back the servers public key filename format, it is better
3914 than the new one. For now, the client keys are saved with the
3915 new filename format. The affected file silc/client_ops.c.
3917 * Implemented the Cipher API for the rest of the ciphers that
3918 did not implement it or implemented it the wrong way.
3920 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Register default ciphers and stuff when using the -S option
3923 in the client. Affected file silc/silc.c. Same also when
3924 creating new key pair with -C option.
3926 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Fixed the silc_verify_public_key client operation function to
3929 save the public keys differently. The fingerprint is now
3930 used as filename and not the hostname. This way also the
3931 client keys are saved uniquely and not with hostnames. The
3932 affected file is silc/client_ops.c.
3934 * Trimmed the silc_hash_fingerprint function to remove extra
3935 whitespaces from the end of the fingerprint. The affected
3936 file is lib/silccrypt/silchash.c.
3940 * Added silc_cipher_register_default function to register all
3941 default ciphers. It can be used when configuration files
3942 does not exist and the application does not want any specific
3943 ciphers in any specific order.
3945 The SilcDList is now used as silc_cipher_list dynamically
3946 allocated cipher list. Removed the static list all together
3947 and now all ciphers must be allocated to the dynamic list.
3948 The silc_cipher_alloc routine was changed to check only the
3951 All silc_cipher_* routines that used to return int returns
3954 The affected files lib/silccrypt/silccrypt.[ch].
3956 * The same thing was done to silc_hash_* as for silc_cipher_*
3957 routines. Affected files lib/silccrypt/silchash.[ch].
3959 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3960 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3961 Added also silc_pkcs_[un]register[_default] functions.
3962 Removed the data_context from the PKCS API.
3964 * Added silc_hmac_register_default function to register default
3965 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3966 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3967 to unregister all hmacs at once.
3969 * Register the default ciphers, hash functions, PKCSs and HMACs
3970 if client's configuration file does not exist. The affected
3973 * The client did not load the hash functions from the SIM
3974 modules at all. Added support for this. Affected file is
3975 silc/clientconfig.c.
3977 * When decoding public key with silc_pkcs_public_key_decode, check
3978 the supported algorithm only if PKCS are registered. Affected
3979 file lib/silccrypt/silcpkcs.c. The same was done with the
3980 silc_pkcs_private_key_decode.
3982 * Fixed the SILC List routines to keep the list always in order.
3983 It used to change the list's order when traversing the list but
3984 not it preserves the order. Affected file lib/trq/silclist.h.
3986 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Added the client library to use the SilcSocketConnection's
3989 reference counter (by silc_socket_dup) to prevent the bug that
3990 the socket object may be freed underneath async operation.
3992 * The name resolv library checking fixes in the configure.in.pre.
3995 * Created new version of the protocol drafts for future
3996 development. The -03 drafts are the ones that will be changed
3997 in the trunk now and the -02 will remain as they are.
3999 * Send list of CUMODE notifys to the router when announcing
4000 the channel users to the router. Affected file silcd/server.c.
4001 If the router receiving channel founder CUMODE for a channel
4002 that already has channel founder it will send CUMODE notify
4003 to the sender to remove the channel founder rights from the
4004 announced client. Affected file silcd/packet_receive.c.
4006 * The CUMODE notify may now use Server ID as well as the entity
4007 who changes the mode. Updated protocool specs.
4009 * Updated INSTALL and README files.
4011 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * New web pages in the http://silc.pspt.fi. The pages was
4018 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Implemented the [DenyConnectin] config section in the server.
4021 Added silc_server_config_denied_conn to check whether incoming
4022 connection is denied. Affected file silcd/serverconfig.[ch].
4024 * Do not check the ports when checking the incoming configuration
4025 data if the port is 0, meaning any. Affected file is
4026 silcd/serverconfig.c.
4028 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Fixed buffer overflow in silc_string_compare in the file
4031 lib/silcutil/silcutil.c.
4033 * Fixed double free in silc_server_command_leave in the file
4036 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed the version checking in the server. Affected file is
4041 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Fixed the configuration data fetching when accepting new
4044 connections in the server. Affected file silcd/server.c.
4046 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added `sender_entry' argument to the function
4049 silc_server_packet_relay_to_channel so that we can check
4050 whether some destination actually belongs to the same route
4051 the sender belongs (ie, we must not resend the packet to the
4052 sender). Affected file silcd/packet_send.[ch].
4054 * Added `servername' field to the SilcClientEntry in the server
4055 to hold the name of the server where client is from. Affected
4056 file is silcd/idlist.h.
4058 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Moved the channel message encrypting in the router betwen
4061 router connections from silc_server_channel_message to the
4062 silc_server_packet_relay_to_channel since we want to check
4063 whether we have anybody channel before encrypting anything.
4064 Affected files silcd/packet_[receive/send].c.
4066 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Fixed the [AdminConnection] server config section to support
4069 multiple entries. Affected file silcd/serverconfig.c.
4071 * Added support into the server to check the validity of the
4072 incoming connection before executing any KE or authentication
4075 * The connection configuration is now saved to the KE and
4076 connection auth protocol contexts and not fetched anymore in
4077 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4079 * The local hosts listenning address and port is also resolved
4080 now when starting the server. We want to have the socket object
4081 to include the real address and port for the listener. Added
4082 new function silc_net_check_local_by_sock into the files
4083 lib/silcutil/silcnet.[ch].
4085 * Fixed a broadcast bug in server -> do not broadcast if we
4088 * Fixed a routing bug. Do not route broadcast packets ever.
4089 Broadcast packets must be processed always and not routed since
4090 they may be destined to some other host than yourself and thus
4091 would get routed without no good reason. Affected file is
4094 * Added function silc_server_config_is_primary_route to check
4095 whether primary router connection has been configured (a router
4096 configuration that we are initiating). If there is not, we
4097 will assume that there is only two routers in the SILC network
4098 and we will use the incoming router connection as our primary
4099 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4101 * Changed the order of the broadcasting. Broadcast _after_ the
4102 packet has been processed not before. Affected file is
4105 * Fixed a [ClientConnection] parsing bug. The port was never
4106 parsed correctly thus resulting to port 0. Affected file
4107 silcd/serverconfig.c.
4109 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4110 argument and did not set the broadcast packet flag. Affected
4111 file silcd/packet_send.c. Fixed same bug in the function
4112 silc_server_send_notify as well.
4114 * If we receive NEW_ID packet for our own ID in the server, ignore
4117 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Removed the nickname from the Private Message Payload.
4122 Updated the code and the protocol specs.
4124 * Updated protocol specs for submitting to the IETF.
4126 * Tweaked the Random Number Generator a bit. Affected file
4127 lib/silccrypt/silcrng.c. Exported a new function
4128 silc_rng_[global]_add_noise which can be used to add more
4131 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Do not parse packets with different timeout when protocol
4134 is active -> may cause problem with rekey. Affected file
4137 * When server receives signoff notify it must not create
4138 new channel key if the client is on any channels since the
4139 sender of the signoff notify will create it.
4141 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Added printing of error messages during SKE protocol from the
4144 failure packet sent by server during SKE. Affected file
4147 * Removed the client's failure_callback handling with timeout
4148 and handle it immediately when received.
4150 * The SKE library returned wrong type in SUCCESS and FAILURE
4151 packets. They must be 32 bit MSB not 16 bit MSB.
4153 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Ok, rewrote the logic of the re-key and now it seems to work.
4156 I tested it on high traffic with frequent re-keys without
4157 problems. Added hmac_receive (and renamed hmac to hmac_send)
4158 in SilcClientConnection in lib/silcclient/client.h and
4159 in SilcIDListData in silcd/idlist.h. Also, removed the
4160 SilcPacketParserContext's cipher and hmac fields as they are
4161 not needed anymore and actually caused some problems when
4162 the ciphers and hmac's changed underneath the packet parser.
4164 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * If re-key protocol is active then process the incoming packets
4167 synchronously since we must assure that icoming packets encrypted
4168 with the old key is processed before the new keys is set to
4169 use. This is true other packets than for REKEY packets.
4170 Affected file silcd/server.c. The same was done to client library
4171 as well, affected file lib/silcclient/client.c.
4173 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Fixed bug in client and server to accept the force send if
4176 the packet is send from silc_[server/client]_packet_process
4177 function. Otherwise the packets are never delivered, oops.
4179 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Disable force sending of packets when REKEY protocol is active.
4182 We must assure that no packet is sent directly when rekey is
4183 performed. All packets must be sent through packet queue.
4184 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4185 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4186 function is silc_[server/client]_packet_send_real to check
4189 * Replaced the SIM paths from example config files to
4190 /usr/local/modules. Also, make install creates now
4191 /usr/local/silc/logs directory to hold all the SILC server
4194 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Made the configure.in.pre work on Solaris. Patch by salo.
4198 * Made all ciphers compatible with non-x86 machines. Defined
4199 CBC mode macros into lib/silccrypt/ciphers_def.h.
4201 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Fixed the make install.
4205 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * When MAC computation fails the silc_packet_decrypt returned 0
4208 even though it was supposed to return -1. Fixed this. The
4209 affected file is lib/silccore/silcpacket.c.
4211 * Do not replace the config files in /etc/silc (in make install)
4212 if they already exist. Affected file ./Makefile.am.
4214 * Do not send re-key packets immediately but through packet queue.
4215 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4217 * Changed silc_net_check_host_by_sock to return FALSE if the
4218 IP/DNS could not be resolved. Though, it returns the IP address
4219 now even if it could not resolve it (but returns also FALSE).
4220 Affected file lib/silcutil/silcnet.[ch].
4222 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added silc_pkcs_decode_identifier to decode the public key's
4225 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4226 Added also silc_pkcs_free_identifier. Added also new context
4227 SilcPublicKeyIdentifier.
4229 * Added -S option to the silc client. It is used to dump the
4230 contents of the specified public key file.
4232 * Changed the PKCS api to return the public key length when
4233 setting the public key.
4235 * Fixed a fatal bug in the public and private key file loading.
4236 Affected file lib/silccrypt/silcpkcs.c.
4238 * Execute the packet parsing for client with zero (0) timeout
4239 if the protocol is active. Affected file silcd/server.c.
4241 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Made the key generation options to the silcd program. Added
4244 -C option, equivalent to client's option.
4246 * Added new [ServerKeys] config section to the server. It
4247 configures the server's public and private key.
4249 * Defined generic Public Key Payload into the protocol
4250 specification to send specific type of public keys and
4253 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4254 public key or certificate.
4256 * Implemented the GETKEY command to the server and to the
4257 client library and on user interface.
4259 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Made preliminary `make install' work.
4263 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added SilcServerRekey context into silcd/idlist.h.
4267 * Added the PFS support as defined in the specification to the
4268 SKE protocol. Affected files lib/silcske/*.c.
4270 * Added `ske_group' field to the SilcServerRekey context to hold
4271 the number of the SKE group that is used with PFS in re-key.
4272 Affected file silcd/idlist.h.
4274 * Added PFS re-key support to the server. Affected file is
4277 * Added silc_protocol_cancel to cancel execution of the next
4278 state of the protocol. Affected file is
4279 lib/silccore/silcprotocol.[ch].
4281 * Added the re-key support with and without PFS to the client
4282 library. Re-key is performed once in an hour, by default.
4284 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4285 Added silc_client_rekey_callback and silc_client_rekey_final.
4286 Affected files are lib/silcclient/protocol.[ch] and
4287 lib/silcclient/client.[ch].
4289 * Removed the `hmac_key' and `hmac_key_len' fields from the
4290 SilcClientConnection structure; not needed. Affected file is
4291 lib/silcclient/client.h.
4295 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Do not ask whether user wants to use the negotiated private key
4298 for private messages, just use it. Affected file is
4299 silc/local_command.c.
4301 * Added `send_enc_key' and `enc_key_len' fields to the
4302 SilcIDListData structure since they are needed in the re-key
4303 phase. Affected file is silcd/idlist.[ch].
4305 * Implemented the simple re-key protocol into the server.
4306 Affected files silcd/server.c and silcd/protocol.[ch]. The
4307 re-key will be performed once in an hour, by default.
4309 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4310 Added silc_server_rekey, silc_server_rekey_callback and
4311 silc_server_rekey_final.
4313 * Removed Tunneled flag from the protocol. Updated the code
4314 and the specifications.
4316 * Adde `pfs' field to the SilcIDListData to indicate whether
4317 the PFS is to be performed in the re-key. Affected file is
4320 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4323 int64 of at least the xintXX size. If void * is less that 4
4324 bytes uint32 * will be used. Defined bool as boolean.
4326 * Changed _ALL_ unsigned long and unsigned int to uint32,
4327 unsgined short to uint16 in the source tree.
4329 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4330 not handle clients that has entry->data.registered == FALSE.
4331 They are not in the network anymore. Affected file is
4334 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Implemented the sending of the SERVER_SIGNOFF notify in the
4337 server. Affected file is silcd/server.c.
4339 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4340 Added also silc_notify_payload_encode_args into the
4341 lib/silccore/silcnotify.[ch].
4343 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4344 Affected file silcd/packet_receive.c.
4346 * Implemented the SERVER_SIGNOFF notify handling in the client
4347 library. Affected file lib/silcclient/client_notify.c. Also,
4348 implemnted the printing of the SERVER_SIGNOFF info to the
4349 application. Affected file silc/client_ops.c.
4351 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4352 if the deleting was successful. Affected file silcd/idlist.[ch].
4354 * Added support for public key authentication in the connection
4355 authentication protocol in the client library. Affected file
4356 lib/silcclient/protocol.c.
4358 * Changed the server's silc_idlist_get_clients_by_* interface
4359 to support already allocated array so that new entries may be
4360 added to pre-allocated array. Affected file silcd/idlist.[ch].
4361 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4362 and command replies.
4364 * All command reply functions in the server now calls the
4365 pending command callback even if error occured. This way the
4366 error will be delivered to the client as well. Affected files
4367 silcd/command.c and silcd/command_reply.c.
4369 * Fixed INFO command to return local server's info if no server
4370 was provided. Affected file lib/silcclient/command.c.
4372 * Removed RESTART command for good. Updated the code and the
4375 * Rewrote parts of the task system. It is a bit simpler now.
4376 Removed unsued task priorities. The affected files are
4377 lib/silcutil/silctask.[ch].
4379 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Moved the USERS printing from the library to the application.
4382 Affected files lib/silcclient/command.c and silc/client_ops.c.
4384 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Added channel key re-key support. The re-key is perfomed
4389 only by the router and is done once in an hour. Added `rekey'
4390 field to the SilcChannelEntry in the server. Affected files
4391 silcd/server.c and silcd/idlist.h.
4393 * Added silc_task_unregister_by_context into the file
4394 lib/silcutil/silctask.[ch].
4396 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Added SILC_UMODE_GONE mode to indicate when the client is not
4399 present in the SILC network. Added also support to the local
4400 command AWAY that will set this mode. Added support of showing
4401 "xxx is gone" in WHOIS command. The USERS command shows the
4402 gone status as well.
4404 * Fixed setting server and router operator privileges in the
4405 server's UMODE command. Affected file silcd/command.c.
4407 * Merged the SKE KE1 and KE2 payloads into one payload. The
4408 new KE payload is equivalent to the old KE2 payload.
4410 Cleaned up the SKE Start Payload parsing. It now uses the
4411 simple buffer unformatting to do the parsing. A lot faster
4414 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4415 to the SKE that is used to indicate whether both of the SKE
4416 parties should perform authentication. By default only the
4417 responder performs authentication. By setting this flag also
4418 the initiator must do authentication. By default it is unset
4419 since in normal SKE case, client to server connection, only
4420 the responder should do authentication. When doing SKE between
4421 two clients both should perform authentication. Updated the
4422 code and the protocol specs.
4424 * A little fix to IDENTIFY command in the server. Search the
4425 client first by hash not nickname. Affected file is
4428 * Fixed the silc_client_close_connection to support closing
4429 the client to client connections wihtout deleting too much
4430 data. Affected file lib/silcclient/client.c.
4432 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4433 are received if protocol used to be active but is not anymore
4434 the application would crash due to NULL pointer dereference.
4435 Affected files silcd/server.c and lib/silcclient/client.c.
4437 * Added `hash' field to the SilcClientConnection to include
4438 the hash function negotiated in the SKE protocol.
4440 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4441 to set the channel founder authentication data. A client can
4442 claim the founder rights later by providing the authentication
4443 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4444 This way the channel founder can regain the channel founder
4445 privileges even it is left the channel. This works only on
4446 local server and the client must be connected to the same
4447 server to be able to regain the founder rights. Updated the
4448 protocol specs accordingly.
4450 Added support to the CMODE command in the client to set the
4451 founder auth data. Read the README to see how to set it.
4453 Added support to the CUMODE command to claim the founder
4454 rights. Read the README to see how to do it.
4456 Added support for the founder authentication to the Channel
4457 Entry in the server. Affected file silcd/idlist.h.
4459 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4460 server's CMODE command. Affected file silcd/command.c.
4462 * Added the following new functions into lib/silccore/silcauth.[ch]:
4463 silc_auth_get_method and silc_auth_get_data.
4465 * The server now saves the remote hosts public key to the
4466 SilcIDListData pointer. Affected file silcd/protocol.c.
4468 * The normal server now does not remove the channel entry from
4469 the cache if the founder authentication data is set. It used
4470 to remove it if the founder was the last one on the channel on
4471 the server and left the channel. The auth data is saved and
4472 if the channel is re-joined later the old entry is used with
4473 the old auth data. Affected files silcd/command_reply.c and
4476 * Removed the `pkcs' field from the SilcIDListData structure
4477 in the server; it is not used. Affected file silcd/idlist.h.
4479 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed packet processing on slow links. Partial packets were
4482 never re-processed because the incoming data buffer was cleared
4483 by the application. Application must not directly clear the
4484 sock->inbuf, the packet processing routines handle it. Fixed
4485 this in client library and in server.
4487 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Fixed the WHOIS and IDENTIFY send reply function to really
4490 check whether to send list or just one entry. Affected file
4493 * Cleaned up the LEAVE command's channel key distribution. The
4494 affected file silcd/command.c.
4496 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4497 can enforce the channel mode as well. In that case the ID
4498 includes the ID of the server. The code now enforces the
4499 mode change if the router have different mode than the server.
4501 * The notify client operation with CMODE_CHANGE notify can now
4502 return NULL client_entry pointer if the CMODE was not changed
4503 by client. Application must check for this.
4505 * Added <Server ID> argument to INFO command to support server
4506 info fetching by Server ID.
4508 * Added silc_server_announce_get_channel_users to get assembled
4509 packets of channel users of the specified channel. Affected
4510 file silcd/server.[ch].
4512 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4513 was freed underneath the ID Cache.
4515 * Re-announce clients when the server received CHANNEL_CHANGE
4516 notify from the router. Affected file silcd/packet_send.c.
4518 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4521 crashed since it did not handle the fact that there is no cipher
4522 called "3" and didn't check the error condition. Now fixed.
4524 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4525 flag. It can be used to send message requests.
4527 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Implemented the RESTART command in the client.
4531 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4532 notice type messages. Added notice printing to the user
4535 * The channel keys are not re-generated if the channel's mode
4536 is PRIVKEY, ie private key on the channel exists. Affected
4537 files silcd/server.c and silcd/command.c.
4539 * Fixed a little bug in channel message delivery when channel
4540 private keys are set in the server. Affected file is
4541 silcd/packet_send.c.
4543 * Changed the setting on channel->on_channel = TRUE from the
4544 silc_client_save_channel_key to the JOIN command reply. The
4545 key payload is not received if the private channel key is set.
4546 Affected file lib/silcclient/command_reply.c and the
4547 lib/silcclient/client_channel.c.
4549 * When the CMODE_CHANGE notify is sent and the channel private
4550 key mode is removed the channel key must be re-generated in
4551 other cells as well. Added this support for the router in the
4552 silcd/packet_receive.c.
4554 * Added new local command NOTICE to send notice message on
4555 channel. Affected file silc/local_command.[ch].
4557 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Added new local command ME to the client. It is used to send
4560 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4561 some action. Affected file silc/local_command.[ch].
4563 * Changed channel_message and private_message client operations
4564 to deliver the message flags to the application. Added also
4565 the `flags' arguments to the silc_client_send_channel_message
4566 and silc_client_send_private_message functions. Affected file
4569 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Redefined the Private Message Payload to support private message
4572 keys and to support the new private message flags. Updated
4573 the protocol specs. Flags makes it possible to have for example
4574 CTCP style messages.
4576 * Added new type SilcPrivateMessagePayload and defined an API
4577 for it in the lib/silcclient/silcprivate.[ch].
4579 * Tested private message private keys successfully. Tested the
4580 private message key set, unset and list commands with the new
4583 * Redefined the Channel Message Payload to include the channel
4584 message flags (equal with private message flags) to support
4585 for example CTCP style messages.
4587 * Defined some of the message (for channel and private message)
4588 flags. Updated the protocol specs and added the flags to the
4589 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4591 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Added SilcKeyAgreementStatus type to the key agreement routines
4594 to indicate the current status and error if one occured.
4595 The status types are defined in the lib/silcclient/silcapi.h.
4597 * Added new local command KEY that is used to set and unset private
4598 keys for channels, set and unset private keys for private messages
4599 with remote clients and to send key agreement requests and
4600 negotiate the key agreement protocol with remote client. The
4601 key agreement is supported only to negotiate private message keys,
4602 it currently cannot be used to negotiate private keys for channels,
4603 as it is not convenient for that purpose.
4605 * Fixed a minor pending callback setting bug in the function
4606 silc_client_get_client_by_id_resolve, now the function works.
4607 Affected file lib/silcclient/idlist.c.
4609 * Added function silc_net_get_local_port to get local bound
4610 port by socket. Added to lib/silcutil/silcnet.[ch].
4612 * Added `sockets' and `sockets_count' fields to the SilcClient
4613 object. They hold the sockets of the listenning sockets in
4614 the client. Listenning sockets may be for example the key
4615 agreement server. Affected file lib/silcclient/client.[ch].
4616 Added functions the silc_client_add_socket and the
4617 silc_client_del_socket. They are exported to the application
4620 * Added ~./silc/clientkeys to support other client's public keys.
4622 * Renamed verify_server_key client operation to verify_public_key
4623 and added one argument to indicate the type of the connection
4624 (server, client etc.).
4626 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Added silc_server_connection_auth_request to handle the
4629 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4630 silcd/packet_receive.[ch].
4632 * Added silc_server_send_connection_auth_request into the
4633 silcd/packet_send.c to send the connection auth request packet.
4635 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4638 * Fixed the public key authentication in responder side in the
4639 server. The `auth_data' pointer includes the SilcPublicKey
4640 not the path to the public key. Affected file silcd/protocol.c.
4642 * Implemented the public key authentication in the initiator side
4643 in the server. Affected file silcd/protocol.c.
4645 * Removed the [RedirectClient] config section from the server
4646 configuration. Is not needed and I don't want to implement it.
4648 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Cleaned up the CMODE command in the server. It now works
4651 correctly and supports all the modes defined in the protocol.
4652 Affected file is silcd/command.c.
4654 * Added `hmac_name' field to the SilcChannelEntry in the server
4655 to hold the default HMAC of the channel. It can be set when
4656 creating the channel (with JOIN command). Affected files
4659 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4660 type to indicate the change of the current cipher and hmac
4661 on the channel. Client can safely ignore the <cipher> argument
4662 (if it chooses to do so) since the CHANNEL_KEY packet will
4663 force the channel key change anyway. The <hmac> argument is
4664 important since the client is responsible of setting the new
4665 HMAC and the hmac key into use.
4667 * Fixed the CMODE command in the client library as well.
4669 * Tested CMODE command in router environment successfully.
4671 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Show the version of the remote client (or server) when connecting
4674 to the server. It is logged to the log file. Affected file
4675 is silcd/protocol.c.
4677 * Fixed the KILLED notify handling in the client library. The
4678 client must be removed from all channels when receiving the
4681 Also, do not remove the client entry when giving the KILL
4682 command but when the KILLED notify is received.
4684 * Removed silc_idlist_find_client_by_nickname from the server.
4685 Not needed anymore. Affected files silcd/idlist.[ch].
4687 * Implemented the CHANNEL_CHANGE notify type handling to the
4688 server. Affected file silcd/server.c.
4692 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added silc_server_send_notify_invite to send the INVITE
4695 notify between routers.
4697 * Implemented the INVITE command correctly to the server.
4699 * Implemented the INVITE notify type handling in the server.
4701 * Implemented the INVITE command to the client library and on the
4704 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Added function silc_server_get_client_resolve to find the
4707 client entry by ID from all ID lists and then resolve it
4708 (using WHOIS) if it cannot be found. Affected file is
4711 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Implemented the BAN command to the client library.
4715 * The JOIN command in the server now checks the invite list
4718 * Changed the silc_command_reply_payload_encode_va and the
4719 silc_command_payload_encode_va to support that if argument is
4720 NULL it ignores and checks the next argument. Affected file
4721 lib/silccore/silccommand.c.
4723 * Added silc_server_send_notify_ban to send the BAN notify
4724 type between routers.
4726 * Chaned the silc_notify_payload_encode to support that if
4727 argument is NULL it ignores and checks the next argument.
4728 Affected file lib/silccore/silcnotify.c.
4730 * Tested ban lists in router environment successfully.
4732 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Implemented BAN command to the server, in silcd/command.[ch].
4736 * Removed the BAN and INVITE_LIST modes from the CMODE command
4739 * Added function silc_string_match to regex match two strings.
4740 Affected files lib/silcutil/silcutil.[ch].
4742 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Redefined parts of the SilcChannelEntry in the server to support
4745 the new ban and invite lists.
4747 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Redefined the INVITE command. The same command can be used to
4750 invite individuals to the channel but also to manage the invite
4751 list of the channel (to add to and remove from the invite list).
4752 Updated the protocol specs.
4754 * Added new command SILC_COMMAND_BAN that can be used to manage
4755 the ban list of the channel. Updated the protocol specs.
4757 * Removed the channel modes: the SILC_CMODE_BAN and the
4758 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4759 in the CMODE command. The equivalent features are now available
4760 using INVITE and BAN commands. Updated the protocol specs.
4762 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4763 in the network about change in the current ban list. The notify
4764 type is not used by the client.
4766 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4767 support the invite lists.
4769 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Added new function silc_string_regexify that converts string
4772 including wildcard characters into regex string that can
4773 be used by the GNU regex library. Added into the file
4774 lib/silcutil/silcutil.[ch].
4776 Added silc_string_regex_combine to combine to regex strings
4777 into one so that they can be used as one regex string by
4778 the GNU regex library. Added into the file
4779 lib/silcutil/silcutil.[ch].
4781 Added silc_string_regex_match to match two strings. It returns
4782 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4784 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Imported GNU regex to the soruce tree into lib/contrib.
4787 Fixed some compiler warning from the regex.c.
4789 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Fixed MOTD command in the server to work in router environment.
4793 * Fixed the MOTD command in the client library to support
4794 the server argument in the command.
4796 * Added `nickname_len' argument to the silc_idlist_add_client
4797 in the server, as the `nickname' argument may be binary data
4800 * Added silc_idlist_get_channels to return all channels from
4803 * Implemented LIST command to the server. Affected file is
4806 * Implemented the LIST command to the client library and on the
4809 * Added [<user count>] argument to the LIST command reply.
4810 With private channels the user count is not shown.
4812 * Updated TODO and README.
4814 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * The client entry's data.registered must be TRUE even with
4817 global client entry on global client list. The data.registered
4818 is used to check whether the client is anymore in the network,
4819 for example with WHOWAS command so it must be valid.
4821 * Fixed the WHOWAS command in the server. It now actually works
4822 in router environment. Added function into silcd/command_reply.c
4823 silc_server_command_reply_whowas_save.
4825 * Added silc_idlist_purge function to the silcd/idlist.c
4826 to periodically purge the ID Cache.
4828 * Fixed INFO command in the server. It works now in router
4829 environment. Added <server name> argument to the INFO command
4830 reply. Updated the protocol specs.
4832 * Fixed minor bug in silc_idcache_purge to not purge if the
4833 expire value is zero.
4835 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4836 they were buggy because of the WHOWAS information.
4838 * Fixed local command MSG to handle the async resolving of
4839 the remote client properly. It used to fail the first MSG.
4840 Affected file silc/local_command.c.
4842 * Added `data_len' field to SilcIDCache context.
4844 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Update TODO. Todo in commands in the server.
4848 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4851 used by routers as broadcast packet to inform other routers
4852 about the changed user mode.
4854 Implemented the notify handling in the server. Affected file is
4855 silcd/packet_receive.c. Added the function
4856 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4858 * Added new generic Channel Payload and deprecated the New Channel
4859 Payload. The New Channel Payload is now the generic Channel
4862 * Added new argument `mode' to the silc_server_send_new_channel
4863 as it is required in the Channel Payload now.
4865 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4866 and created a new and real SilChannelPayload to represent the
4867 new generic Channel Payload. Implemented the encode/decode
4868 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4870 * Added silc_server_get_client_channel_list to return the list
4871 of channels the client has joined for WHOIS command reply.
4872 Affected file silcd/server.[ch].
4874 * Implemented the channel list sending in the WHOIS command reply
4875 in server and in the client.
4877 Implemented the channel list displaying on the user interface
4878 as well. Affected file silc/client_ops.c.
4880 * Added silc_channel_payload_parse_list to parse list of Channel
4881 Payloads. It returns SilcDList list of SilcChannelPayloads.
4882 Client for example can use this function to parse the list of
4883 channels it receives in the WHOIS command reply. The caller
4884 must free the list by calling silc_channel_payload_list_free.
4885 Affected files lib/silccore/silcchannel.[ch].
4887 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added one new argument <user mode> to the WHOIS command reply
4890 to return the mode of the user in SILC. Updated the protocol
4893 Implemented it to the server and client.
4895 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Fixed the mode printing on the user interface on joining.
4898 Affected file silc/client_ops.c.
4900 * Implemented the UMODE command and user modes in general to the
4901 client library and to the user interface.
4903 * Implemented the UMODE command to the server.
4905 * The server now sends UNKNOWN_COMMAND error status if client sends
4906 unknown command. Affected file silcd/command.c.
4908 * All server commands now handle the command identifier the right
4909 way when sending the command reply to the client. The client can
4910 use to identify the command replies with the identifier.
4912 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added silc_server_get_client_route to resolve the route to
4915 the client indicated by the client ID. Affected file is
4918 * Added silc_server_relay_packet as general function to relay
4919 packet to arbitrary destination. This deprecates functions
4920 like _send_private_message_key, _relay_notify etc. Affected
4921 file is silcd/packet_send.[ch].
4923 Removed silc_server_send_key_agreement,
4924 silc_server_send_private_message_key and
4925 silc_server_packet_relay_notify functions from the file
4926 silcd/packet_send.[ch].
4930 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4931 server. Affected file silcd/packet_receive.[ch].
4933 * Implemented the KILL command to the client. Implemented the
4934 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4935 Affected files lib/silcclient/command[_reply].c and
4936 lib/silcclient/client_notify.c. Implemented the KILL notify
4937 printing in the user inteface.
4939 * Fixed a lot silc_parse_nick memory leaks from the client
4940 library in the file lib/silcclient/command.c.
4942 * Changed the silc_server_send_notify_on_channels's `sender'
4943 argument from SilcSocketConnection to SilcClientEntry to
4944 check the sender as entry and not as connection object and not
4945 to send to the client provided as argument. The affected file
4946 is silcd/packet_send.[ch].
4948 * The notify packets that are destined directly to the client used
4949 to not to be processed by the server. Now changed that and the
4950 server processes all notify packets. After relaying the packet
4951 to the client the notify packet is processed in the server.
4953 * The silc_server_free_client_data now checks whether there is
4954 pending outgoing traffic for the client and purges the data to
4955 the network before removing the client entry.
4957 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4960 an client is killed from the SILC Network. Updated the protocol
4963 Added new function silc_server_send_notify_killed to the
4964 silcd/packet_send.[ch].
4966 * Added function silc_server_packet_relay_notify to relay notify
4967 packets that are destined directly to a client. In this case
4968 the server does not process the notify packets but merely relays
4969 it to the client. Affected file silcd/packet_send.[ch].
4971 Added also silc_server_packet_process_relay_notify to check
4972 whereto relay the notify. Affected file is
4973 silcd/packet_receive.[ch].
4975 * Implemented the KILL command to the server.
4979 * Added the backup schema desgined last fall to the protocol
4980 specs for everyone to see. The specification is in the
4981 *-spec-xx.txt draft and the packet type definitions for the
4982 backup routers is in *-pp-xx.txt draft. Thusly, added also
4983 new packet type SILC_PACKET_CELL_ROUTERS.
4985 * A big security problem in the implementation discovered. The
4986 signoff of an client did not cause new channel key generation
4987 which it of course should've done. The channel keys must be
4988 always re-generated when client leaves (or signoffs) the channel.
4989 The silc_server_remove_from_channels funtion now handles
4990 the channel key re-generation.
4992 * Added `sender' argument to the silc_server_send_notify_on_channels
4993 to not to send the client provided as argument. Affected file
4994 silcd/packet_send.[ch].
4996 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Implemented OPER and SILCOPER commands into the server and
5001 * Added silc_auth_verify and silc_auth_verify_data to verify
5002 the authentication directly from the authentication payload.
5003 It supports verifying both passphrase and public key based
5004 authentication. Affected file lib/silccore/silcauth.[ch].
5006 * Added `hash' field to the SilcIDListData structure. It is the
5007 hash negotiated in the SKE protocol. Affected file is
5010 * Slight redesigning of the SilcAuthPayload handling routines.
5011 Do not send SilcPKCS but SilcPublicKey as argument.
5013 * Implemented the public key authentication support to the
5014 serverconfig. The public key is loaded from the provided path
5015 and saved as authentication data to void * pointer. Thus,
5016 changed the unsigned char *auth_data to void *auth_data;
5018 * Fixed SHUTDOWN command to send the reply before the server
5019 is shutdown. :) Affected file silcd/command.c.
5021 * Fixed fatal bug in CONNECT command. The hostname was invalid
5022 memory and server crashed. Affected file silcd/command.c.
5024 * Fixed fatal bug in CLOSE command. The server_entry became
5025 invalid but was referenced later in the command. Affected file
5028 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed fatal bug in failure packet handling. Server ignored
5031 the failure and thus crashed when it came.
5035 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5038 that the command may be executed only once in (about) 2 seconds.
5039 The old SILC_CF_LAG flag is same but allows command bursts up
5040 to five before limiting.
5042 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5043 server code. Various commands now includes the CF_LAG_STRICT
5044 flag to disallow any kind of miss-use of the command.
5046 * Fixed the silc_buffer_unformat to not to allocate any data
5047 if the length of the data is zero. It used to allocate the
5048 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5050 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Changed the format of AdminConnection configuration section
5053 in the server. Added username of the admin to the format.
5054 Affected files silcd/serverconfig.[ch].
5056 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5057 to return admin configuration data by host, username and/or
5060 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Implemented WHOWAS command to the server. Added the functions:
5064 silc_server_command_whowas_parse,
5065 silc_server_command_whowas_send_reply,
5066 silc_server_command_whowas_from_client and
5067 silc_server_command_whowas_from_server
5069 * Added <Client ID> argument to the WHOWAS command reply. Updated
5070 the protocol specs accordingly.
5072 * Implemented WHOWAS command and command_reply to the client
5075 Implemented the WHOWAS printing on the user interface.
5077 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added new argument to the WHOWAS command reply, the real name.
5080 It is an optional argument. Updated the protocol specs.
5082 * Added SilcIDCacheDestructor callback that is registered when
5083 the SilcIDCache is allocated. The callback is called when
5084 an cache entry in the ID Cache expires, or is purged from the
5085 cache. Added into lib/silccore/idcache.[ch].
5087 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5088 to destruct the client entries when the cache entry expires.
5089 Other ID Cache's in server and in the client library ignores
5092 * If the ID Cache entry's `expire' field is zero then the entry
5093 never expires. Added boolean `expire' argument to the
5094 silc_idcache_add function in the lib/silccore/idcache.[ch].
5095 If it is TRUE the default expiry value is used.
5097 * Added silc_server_free_client_data_timeout that is registered
5098 when client disconnects. By default for 5 minutes we preserve
5099 the client entry for history - for WHOWAS command.
5101 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added support to the server to enforce that commands are not
5104 executed more than once in 2 seconds. If server receives
5105 commands from client more frequently, timeout is registered
5106 to process the commands. Affected file silcd/command.c.
5107 Added new function silc_server_command_process_timeout.
5109 * Changed NICK_NOTIFY handling in client library to check that
5110 if the client's nickname was changed, so there is no need to
5111 resolve anything from the server.
5113 * Removed error printing from the WHOIS and IDENTIFY commands.
5114 If error occurs then it is ignored silently in the client library.
5115 The application, however, may map the received error to
5116 human readable error string. The application currently maps
5117 the NO_SUCH_NICKNAME error to string.
5119 * Made the command status message public to the application. Moved
5120 them from lib/silcclient/command_reply.c to
5121 lib/silcclient/command_reply.h. The application can map the
5122 received command status to the string with the
5123 silc_client_command_status_message function.
5125 * Added check to the server to check that client's ID is same
5126 as the Source ID in the packet the client sent. They must
5129 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Added dist-bzip hook to the Makefile.am to make bzip2
5132 compressed distributions.
5134 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Server now enforces the maximum length for the nickname and
5137 the channel as protocol specification dictates. 128 bytes for
5138 nickname and 256 bytes for channel name.
5140 * Moved the WHOIS printing to the application. The client libary
5141 does not print out the WHOIS information anymore, the application
5142 must do it. Renamed silc_client_command_reply_whois_print to
5143 the silc_client_command_reply_whois_save.
5145 The client's idle time is also sent to the application now, and
5146 the idle is shown on screen.
5148 * Added silc_client_command_reply_identify_save to save the
5149 received IDENTIFY entries.
5151 * Do not check for channel private keys in message sending and
5152 reception if the channel does not have the PRIVKEY mode set.
5153 Affected file lib/silclient/client_channel.c.
5155 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5158 just surfaced after chaning the JOIN procedure.
5160 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Added silc_client_get_clients_by_list to get client entries
5163 from Client ID list, that is returned for example by JOIN
5164 and USERS command replies. The application should use this
5165 function for example when JOIN command reply is received to
5166 resolve the clients already on the channel (library does not
5167 do that anymore as USERS command reply is not used in the JOIN
5168 procedure anymore). Affected files lib/silcclient/silcapi.h and
5169 lib/silcclient/idlist.c.
5171 * JOIN command reply and USERS command reply returns now SilcBuffer
5172 pointers instead of unsigned char pointers when returning
5173 the client list and mode list.
5175 * Added <Client ID> argument to the JOIN command reply, mainly
5176 for the server to identify for which client the command was
5177 originally sent. Updated protocol specs accordingly.
5179 * Added SilcDlist private_key pointer to the SilcChannelEntry
5180 in the client to support the channel private keys. Affected
5181 file is lib/silcclient/idlist.h.
5183 * Added SilcChannelPrivateKey argument to the function
5184 silc_client_send_channel_message so that application can choose
5185 to use specific private ke if it wants to. If it is not provided,
5186 the normal channel key is used, unless private keys are set.
5187 In this case the first (key that was added first) is used
5188 as the encryption key.
5190 * Implemented the support for channel private key handling.
5191 Implemented the following functions:
5193 silc_client_add_channel_private_key,
5194 silc_client_del_channel_private_keys,
5195 silc_client_del_channel_private_key,
5196 silc_client_list_channel_private_keys and
5197 silc_client_free_channel_private_keys
5199 Affected file lib/silcclient/client_channel.c.
5201 * Added the support for the private keys in the channel message
5202 sending and encryption and in the message reception and
5203 decryption. Affected funtions are
5204 silc_client_send_channel_message and silc_client_channel_message.
5206 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added SKE's key verify callback to the client library's
5209 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5211 * Removed the statement that server (or router) must send USERS
5212 command reply when joining to the channel so that the client
5213 knows who are on the channel. Instead, the client list and
5214 client's mode list is now sent in the JOIN command reply to the
5215 client who joined channel. This is better solution.
5217 * Added function silc_server_get_users_on_channel and function
5218 silc_server_save_users_on_channel to the silcd/server.[ch].
5220 * Removed function silc_server_command_send_users from the
5223 * Do not show topic on the client library anymore. The topic is
5224 sent in the command reply notify to the application and the
5225 application must show the topic now.
5227 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added client searching by nickname hash into the IDENTIFY and
5230 WHOIS commands in the server as they were clearly missing from
5231 them. Affected file is silcd/command.c.
5233 * Fixed a bug in private message receiving in the client library.
5234 The remote ID was freed and it wasn't supposed, now it is
5237 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Minor fix to the channel payload; allocate the data area, as it
5240 needs to be of specific length.
5242 * If the key agreement port is zero then the operating
5243 system will define the bound port. Affected files are
5244 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5246 * Added new function silc_channel_payload_decrypt into the file
5247 lib/silccore/silcchannel.[ch].
5249 * Moved the channel message etc, check from silc_packet_decrypt
5250 to applications. The library calls now a generic
5251 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5252 when the packet is either normal or special. This was done to
5253 allow more wide range of checking that was not allowed when
5254 the code was in library. Now applications can do virtually any
5255 checks to the packet and return to the library the decision how
5256 the packet should be processed. Affected files are
5257 lib/silccore/silcpacket.[ch].
5259 Added silc_server_packet_decrypt_check to the server and
5260 silc_client_packet_decrypt_check to the client library.
5262 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5263 to send with specified source and destination information.
5265 * Channel message delivery between routers was broken after the
5266 channel key distribution was fixed earlier. The channel key
5267 was used be to distributed to other routers as well which is not
5268 allowed by the protocol. Now this is fixed and channel keys
5269 really are cell specific and the channel message delivery between
5270 routers comply with the protocol specification.
5272 * Fixed various commands in server to check also the global list
5273 for the channel entry and not just the local list. The affected
5274 file silcd/command.c.
5276 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Added assert()s to buffer formatting and unformatting routines
5279 to assert (if --enable-debug) when error occurs. Affected
5280 file: lib/silcutil/silcbuffmt.c.
5282 * Changed to auto-reconnect to check whether the remote host is
5283 router and register the re-connect timeout if it is. It used
5284 to check that whether we are normal server, but router must do
5285 auto-reconnect with another router as well. Affected file
5288 * Removed the [<key len>] option from CMODE command as the cipher
5289 name decides the key length, nowadays. See the defined ciphers
5290 from the protocol specification.
5292 * Added [<hmac>] option to the CMODE command to define the HMAC
5293 for the channel. Added SILC_CMODE_HMAC channel mode.
5295 * Added [<hmac>] option for the JOIN command so that user can
5296 select which HMAC is used to compute the MACs of the channel
5299 * Added Hmac field to the Channel Message Payload. The integrity
5300 of plaintext channel messages are now protected by computing
5301 MAC of the message and attaching the MAC to the payload. The
5302 MAC is encrypted. Now, it is clear that this causes some
5303 overhead to the size of the packet but rationale for this is that
5304 now the receiver can verify whether the channel message decrypted
5305 correctly and also when private keys are set for the channel the
5306 receiver can decrypt the packet with several keys and check from
5307 the MAC which key decrypted the message correctly.
5309 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5310 lib/silccrypt/silccipher.[ch].
5312 * Added silc_hash_len to return the digest length into the
5313 lib/silcrypt/silchash.[ch].
5315 * Rewrote parts of Silc Channel Payload interface in the
5316 lib/silccore/silcchannel.[ch]. The encode function now also
5317 encrypts the packet and parse function decrypts it.
5319 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Fixed a minor formatting bug in the SKE's key material processing.
5322 It actually might have processed the keys wrong way resulting
5325 * Redefined the mandatory HMAC algorithms and added new algorithms.
5326 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5327 and hmac-md5 truncated to 96 bits. The mandatory is now
5328 hmac-sha1-96. Rest are optional (including the one that used
5329 to be mandatory). Rationale for this is that the truncated HMAC
5330 length is sufficient from security point of view and can actually
5331 make the attack against the HMAC harder. Also, the truncated
5332 HMAC causes less overhead to the packets. See the RFC2104 for
5335 * Added new [hmac] configuration section. The SKE used to use
5336 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5337 is of course wrong. The official names that must be proposed in
5338 the SKE are the ones defined in the protocol specification
5339 (hmac-sha1-96 for example). The user can configure any hmac
5340 using any hash function configured in the [hash] section. At
5341 least, the mandatory must be configured.
5343 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5345 * Added HMAC list to the SKE proposal list. It has now both
5346 hash algorithm list and HMAC list. This makes the protocol
5347 incompatible with previous versions. The SKE now seems to work
5348 the way it is supposed to work, for the first time actually.
5350 * Defined plain Hash algorithms to the protocol specification.
5353 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Implemented support for key agreement packets into the server.
5356 Added functions silc_server_key_agreement and
5357 silc_server_send_key_agreement. Other than these functions,
5358 server has nothing to do with this packet.
5360 * Added support for private message key packets into the server.
5361 Added functions silc_server_private_message_key and
5362 silc_server_send_private_message_key.
5366 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5367 called in the protocol's final callback instead in the END
5368 protocol state. This makes a little more sense and in the same
5369 time in client we can use the same protocol routines for normal
5370 key exchange and to key agreement packet handling as well.
5372 * Added to both client's and server's KE protocol context the
5373 SilcSKEKeyMaterial pointer to save the key material. We will
5374 bring the key material to the protocol's final callback by doing
5375 this. The final callback must free the key material.
5377 * Added SKE's packet_send callback into client's KE protocol
5378 context so that the caller can choose what packet sending function
5379 is used. This way we can use different packet sending when
5380 doing normal SKE when doing key agreement packet handling (in
5381 the key agreement packet handling we do not want to encrypt
5384 * Implemented the responder side of the key agreement routines
5385 in the client. The client can now bind to specified port and
5386 accept incoming key negotiation. The key material is passed
5387 to the application after the protocol is over.
5389 * Implemented the processing of incoming Key Agreement packet
5390 in the client. Added function silc_client_key_agreement to
5393 * Implemented the intiator side of the key agreement routines
5394 in the client. The client can now initiate key agreement with
5395 another remote client. The key material is passed to the
5396 application after the protocol is over.
5398 * Created client_keyagr.c to include all the key agreement
5401 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5402 SILC_TASK_CALLBACK except that it is not static.
5404 * Created client_notify.c and moved the Notify packet handling
5405 from the client.[ch] into that file.
5407 * Created client_prvmsg.c and moved all private message and
5408 private message key routines from the client.[ch] into that file.
5410 * Create client_channel.c and moved all channel message and
5411 channel private key routines from the client.[ch] into that file.
5413 * Changed silc_client_get_client_by_id_resolve to resolve with
5414 WHOIS command instead of IDENTIFY command, in the file
5415 lib/silclient/idlist.c.
5417 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Implemented the SKE's responder side to the Client library.
5421 * When FAILURE is received to the protocol do not trust it
5422 blindly. Register a timeout to wait whether the remote closes
5423 the connection as it should do it, only after that process the
5424 actual failure. This was changed to both client and server.
5426 * Added client_internal.h to include some of the structures
5427 there instead of client.h in lib/silcclient/.
5429 * Added function silc_task_unregister_by_callback to unregister
5430 timeouts by the callback function.
5432 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Some "Incomplete WHOIS info" errors has been appearing on the
5435 log files. Took away the entry->userinfo check from WHOIS
5436 reply sending. The entry->userinfo is now " " if client did not
5437 provide one. I thought this was fixed earlier but something
5438 is wrong still. Let's see if the error still appears.
5440 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Fixed a minor bug in the login when the channel key is
5443 re-generated in the server. It used to generate the key in
5444 wrong order and thus caused problems in the channel traffic.
5446 * Fixed a minor bug in channel key distsribution after
5447 KICK command. The key was not sent to the router even though
5450 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added silc_ske_process_key_material_data as generic routine
5453 to process any key material as the SILC protocol dictates. The
5454 function is used by the actual SKE library but can be used by
5455 applications as well. This relates to the private message keys
5456 and the channel private keys since they must be processed the
5457 same way the normal SILC session keys. The protocol dictates
5458 this. Affected files: lib/silcske/silcske.[ch].
5460 Added also silc_ske_free_key_material to free the
5461 SilcSKEKeyMaterial structure.
5463 * Defined silc_cipher_set_key function to set the key for
5464 cipher without using the object's method function. The affected
5465 files: lib/silccrypt/silccipher.[ch].
5467 * Implemented silc silc_client_add_private_message_key,
5468 silc_client_add_private_message_key_ske,
5469 silc_client_del_private_message_key,
5470 silc_client_list_private_message_keys and
5471 silc_client_free_private_message_keys functions in the
5474 Added functions silc_client_send_private_message_key to send
5475 the Private Message Key payload and silc_client_private_message_key
5476 to handle incoming Private Message Key payload.
5478 * Added Cipher field to the Private Message Key payload to set
5479 the cipher to be used. If ignored, the default cipher defined
5480 in the SILC protocol (aes-256-cbc) is used.
5482 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Removed lib/silcclient/ops.h file.
5486 Redefined parts of the SILC Client Library API. Created new
5487 file silcapi.h that deprecates the ops.h file and defines the
5488 published Client Library API. Defined also private message key
5489 API and channel private key API into the file.
5491 This is the file that the application must include from the
5492 SILC Client Library. Other files need not be included by
5493 the application anymore.
5495 * Added new key_agreement client operation callback and also
5496 defined the Key Agreement library API for the application.
5498 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5501 is used by clients to request key negotiation between another
5502 client in the SILC network. If the negotiation is started it
5503 is performed using the SKE protocol. The result of the
5504 negotiation, the secret key material, can be used for example
5505 as private message key.
5507 Implemented the Key Agreement payload into the files
5508 lib/silccore/silauth.[ch].
5510 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Redefined ciphers for the SILC protocol. Added some new ciphers
5513 and defined the key lengths for the algorithms. Changed the
5514 code accordingly. The default key length is now 256 bits.
5516 * Fixed SKE key distribution function silc_ske_process_key_material
5517 when the key length is more than 128 bits. The default key
5518 length in SILC is now 256 bits.
5520 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5521 to indicate unsupported algorithm.
5523 * Renamed rijndael.c to aes.c and all functions as well.
5525 * Fixed a long standing channel key setting bug in client library.
5526 Weird that it has never surfaced before.
5528 * Fixed bug in channel deletion. If the entire channel is removed
5529 then it must also delete the references of the channel entry
5530 from the client's channel list as the client's channel entry and
5531 the channel's client entry share same memory.
5533 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Implemented CONNECT and SHUTDOWN commands in the client.
5537 * Implemented CLOSE command to the client.
5539 * Added the function silc_idlist_find_server_by_name into the
5540 files silcd/idlist.[ch].
5542 Added the function silc_idlist_find_server_by_conn into the
5543 files silcd/idlist.[ch].
5545 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * DIE command was renamed to SHUTDOWN. Updated the both code
5550 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5551 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5553 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5556 * Added function silc_server_create_connection function to create
5557 connection to remote router. My server implementation actually
5558 does not allow router to connect to normal server (it expects
5559 that normal server always initiates the connection to the router)
5560 so the CONNECT command is only good for connecting to another
5563 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5566 or some other client was kicked from the channel.
5568 Implemented the handling of the notify type to both client
5571 Implemented silc_server_send_notify_kicked to send the KICKED
5572 notify. It is used to send it to the server's primary router.
5574 * Implemented the KICK command into server and client.
5576 * Added `query' argument to the silc_idlist_get_client function
5577 to indicate whether to query the client from server or not if
5580 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5581 to indicate that the client is not channel founder.
5585 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Removed the rng context from SilcPacketContext structure and
5588 changed that the packet routine uses the Global RNG API.
5590 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added support for quit message that client can "leave" on the
5593 channel when it quits the SILC. It is ditributed inside the
5594 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5596 Added silc_server_free_client_data that will take the
5597 signoff message as argument.
5599 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5601 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Updated parts of the protocol specification to keep it up
5606 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5608 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5609 payloads in one packet.
5611 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5612 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5613 use now the new List flag.
5615 * Also deprecated the following packet types: REPLACE_ID,
5616 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5618 * Added list support for Notify packet in server.
5620 * Added silc_server_send_notify_channel_change to send the
5621 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5622 the silc_server_send_replace_id.
5624 * Added silc_server_send_notify_nick_change to send the
5625 NICK_CHANGE notify type. Deprecates the function
5626 silc_server_send_replace_id.
5628 * Added silc_server_send_notify_join to send the JOIN notify type.
5629 Deprecates the function silc_server_send_new_channel_user.
5631 * Added silc_server_send_notify_leave to send LEAVE notify type.
5632 Deprecates the function silc_server_send_remove_channel_user.
5634 * Added silc_server_send_notify_cmode and
5635 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5636 types. Deprecates the silc_server_send_set_mode function.
5638 * Added SERVER_SIGNOFF notify type to indicate that server has
5639 quit. This means that all clients on the channel from that
5640 server will drop. This can be also used when netsplit happens.
5642 Deprecated REMOVE_ID packet type since it is not needed anymore
5645 Added silc_server_send_notify_server_signoff to send the
5646 SERVER_SIGNOFF notify type. Deprecates the function
5647 silc_server_send_remove_id.
5649 Added also silc_server_send_notify_signoff to send the
5650 SIGNOFF notify type.
5652 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5653 SILC protocol from this day on. Changed the protocol
5654 specification as well.
5656 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5657 notify type. It is used between routers to notify about
5658 topic changes on a channel.
5660 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5663 * Partly updated the protocol specification to comply with the
5664 changes now made. It is still though a bit outdated.
5666 * The JOIN notify type now takes one extra argument <Channel ID>.
5667 The packet used to be destined to the channel but now the
5668 JOIN type may be sent as list thus it is impossible to
5669 destine it to any specific channel. By adding this argument
5670 it is again possible.
5672 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Added CREDITS file. The CHANGES and CREDITS file will appear
5675 in the distribution as well.
5677 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5680 types in the server's silcd/packet_receive.c.
5682 * Implemented CMODE and CUMODE to work in router environment.
5684 * Fixed minor encoding and decoding buglet from the
5685 lib/silccore/silcmode.c.
5687 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5690 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5692 * Changed all SilcConfigServer* and silc_config_server* to
5693 SilcServerConfig* and silc_server_config*, respectively.
5696 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Associated the ID (client or server ID) to the Authentication
5699 Payload to avoid any possibility of forging. Updated the
5700 protocol specification and the code accordingly.
5702 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * The RSA key length is now save to the RsaKey context in the
5705 key generation process in lib/silccrypt/rsa.c. The key length
5706 is now used to figure out the maximum size of the block allowed
5707 to be encrypted/signed.
5709 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5710 is equivalent to the silc_mp_mp2bin but does not allocate any
5713 * Changed silc_mp_mp2bin API to take length argument. If it is
5714 non-zero then the buffer is allocated that large. If zero, then
5715 the size is approximated using silc_mp_sizeinbase, which however
5718 * Created Global RNG API which is global RNG that application can
5719 initialize. After initializing, any routine anywhere in the
5720 code (including library) can use RNG without allocating a new
5721 RNG object. This was done to allow this sort of use of the
5722 RNG in code that has no chance to allocate RNG object. All
5723 applications currently allocate this and many routines in the
5724 library use this. Affected file lib/silccrypt/silcrng.[ch].
5726 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5727 it to use the Global RNG API.
5729 * Defined Authentication Payload into protocol specification that
5730 is used during SILC session to authenticate entities. It is
5731 used for example by client to authenticate itself to the server
5732 to obtain server operator privileges.
5734 Implemented this payload into the lib/silccore/silcauth.[ch].
5735 Implemented also routines for public key based authentication
5736 as the new protocol specification dictates.
5738 Moved definitions of different authentication methods from
5739 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5741 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5742 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5743 silc_pkcs_verify_with_hash functions into the file
5744 lib/silccrypt/silcpkcs.[ch].
5746 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * The client entry's userinfo pointer must be always valid.
5749 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5750 will fail since it requires the userinfo. Now, the userinfo
5751 is allocated as "" if actual userinfo does not exist. Actually,
5752 it must exist and it is totally Ok to drop client connections
5753 that does not announce the userinfo. However, we will make
5754 this workaround for now.
5756 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5757 to return the remote port by socket.
5759 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5762 SILC_SERVER_PENDING_EXEC and added an new macro
5763 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5764 data or when error occurs while processing the pending command.
5766 Added new argument `destructor' into silc_server_command_pending
5767 and to the SilcServerCommandPending object. This destructor is
5768 now called after calling the pending callback or if error occurs
5769 immediately. If error occurs the actual pending callback won't
5770 be called at all - only the destructor. The destructor may be
5771 NULL if destructor is not needed.
5773 All this applies for client library code as well. Similar
5774 changes were made there as well for the pending commands.
5776 In the client, the application must now allocate the
5777 SilcClientCommandContext with the silc_client_command_alloc
5780 * Added reference counter to the SilcServerCommandContext. Added
5781 function silc_server_command_alloc and silc_server_command_dup
5784 Same type of functions added to the client library for the same
5787 * Removed the cmd_ident from IDListData away since it is now
5788 global for all connections. It is the command identifier used
5789 in command sending and with pending commands. The affected file
5792 * Added reference counter to the SilcSocketConnection objecet to
5793 indicate the usage count of the object. The object won't be
5794 freed untill the reference counter hits zero. Currently only
5795 server uses this, and client ignores it. The client must be
5796 set to use this too later. The affected files are
5797 lib/silccore/silcsockconn.[ch]. Added also the function
5798 silc_socket_dup to increase the reference counter.
5800 This was mainly added because it is possible that the socket
5801 is removed underneath of pending command or other async
5802 operation. Now it won't be free'd and proper DISCONNECTING
5803 flags, etc. can be set to avoid sending data to connection that
5804 is not valid anymore.
5806 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5807 the connection. After that it sets SILC_SET_DISCONNECTED.
5808 It is, however, possible that the socket data is not still freed.
5809 The silc_server_packet_process now checks that data is not
5810 read or written to connection that is DISCONNECTED. The socket
5811 get's freed when the reference counter hits zero.
5813 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Changed the client operation API: channel_message operation's
5816 `sender' is now the client entry of the sender, not the nickname
5817 and the `channel' is the channel entry, not the channel name.
5819 In the private_message operation the `sender' is now also the
5820 client entry of the sender not the nickname.
5822 Affected file is lib/silcclient/ops.h and all applications
5823 using the client operations.
5825 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Moved the calling of ops->connect() from connect_to_server_final
5828 into receive_new_id functin since that is the point when the
5829 client is actually allowed to send traffic to network. The
5830 affected file is lib/silcclient/client.c.
5832 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5835 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5836 (if needs broadcasting) instead of broadcasting the packets one
5837 by one which would make a burst in the network traffic.
5839 * Added `broadcast' argument to the functions in silcd/server.[ch]
5840 silc_server_create_new_channel[_with_id] to indicate whether
5841 to send New Channel packet to primary router.
5843 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added new function into the silcd/server.[ch] files:
5846 silc_server_create_new_channel_with_id to create new channel with
5847 already existing Channel ID.
5849 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5850 lib/silccore/silcpacket.h. This packet is used t send list of
5851 Set Mode payloads inside one packet. Server uses this to set
5852 the modes for the channels and clients on those channels, that it
5853 announced to the router when it connected to it. The protocol
5854 specification has been updated accordingly.
5856 * The silc_server_new_channel did not handle the packet coming
5857 from normal server as it normally does not send that. However,
5858 when it announces its channels it does send it. Implemented
5859 the support for that.
5861 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5862 into the file lib/silccore/id.h.
5864 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Fixed memory leaks in the functions silc_idlist_del_client,
5867 silc_idlist_del_channel and silc_idlist_del_server in the file
5868 silcd/idlist.c. All of those leaked like a sieve.
5870 * Fixed some small memory leaks in the client's function
5871 silc_client_notify_by_server.
5873 * Added functions into silcd/server.c: silc_server_announce_clients,
5874 silc_server_announce_channels and silc_server_announce_server.
5875 These functions are used by normal and router server to announce
5876 to its primary router about clients, channels and servers (when
5877 router) that we own. This is done after we've connected to the
5880 These functions effectively implements the following packet types:
5881 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5882 and SILC_PACKET_NEW_ID_LIST.
5884 * Added new functions into the silcd/packet_receive.[ch]:
5885 silc_server_new_id_list, silc_server_new_channel_list and
5886 silc_server_new_channel_user_list to handle the incoming
5887 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5889 * Added support of changing Channel ID in the function
5890 silc_server_replace_id. If the server that announces a channel
5891 to the router already exists in the router (with same name but
5892 with different Channel ID), router is responsible to send
5893 Replace ID packet to the server and force the server to change
5894 the Channel ID to the one router has.
5896 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5897 client that the Channel ID has been changed by the router. The
5898 normal server sends this to the client. Client must start using
5899 the new Channel ID as the channel's ID.
5901 Implemented handling of this new type into lib/silcclient/client.c
5902 into the function silc_client_notify_by_server.
5904 * Added new function silc_idlist_replace_channel_id into the files
5905 silcd/idlist.[ch] to replace the Channel ID.
5907 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Call silc_server_command_identify_check always when processing
5910 the IDENTIFY command in silcd/command.c
5912 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5915 send keepalive packets. The packet can be sent by clients,
5916 servers and routers.
5918 Added function silc_socket_set_heartbeat into the file
5919 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5920 If not set, the heartbeat is not performed. The actual
5921 heartbeat is implemented in the low level socket connection
5922 library. However, application is responsible of actually
5925 Added silc_server_send_heartbeat to send the actual heartbeat
5926 packet into silcd/packet_send.[ch]. Server now performs
5927 keepalive with all connections.
5929 * Added silc_task_get_first function into lib/silcutil/silctask.c
5930 to return the timeout task with shortest timeout. There was a bug
5931 in task unregistration that caused problems. TODO has been
5932 updated to include that task system must be rewritten.
5934 * The client library will now resolve the client information when
5935 receiving JOIN notify from server for client that we know but
5936 have incomplete information.
5938 * Rewrote parts of silc_server_remove_from_channels and
5939 silc_server_remove_from_one_channel as they did not remove the
5940 channel in some circumstances even though they should've.
5942 * Encryption problem encountered in server:
5944 The LEAVE command used to send the Channel Key packet to the
5945 router immediately after generating it. However, the code
5946 had earlier sent Remove Channel user packet but not immediately,
5947 ie. it was put to queue. The order of packets in the router
5948 was that Channel Key packet was first and Remove Channel User
5949 packet was second, even though they were encrypted in the
5950 reverse order. For this reason, MAC check failed. Now, this
5951 is fixed by not sending the Channel Key packet immediately but
5952 putting it to queue. However, this is more fundamental problem:
5953 packets that are in queue should actually not be encrypted
5954 because packets that are sent immediately gets encrypted
5955 actually with wrong IV (and thus MAC check fails). So, packets
5956 that are in queue should be encrypted when they are sent to
5957 the wire and not when they put to the queue.
5959 However, the problem is that the current system has not been
5960 designed to work that way. Instead, the packet is encrypted
5961 as soon as possible and left to the queue. The queue is then
5962 just purged into wire. There won't be any fixes for this
5963 any time soon. So, the current semantic for packet sending
5966 o If you send packet to remote host and do not force the send
5967 (the packet will be in queue) then all subsequent packets to the
5968 same remote host must also be put to the queue. Only after the
5969 queue has been purged is it safe again to force the packet
5972 o If you send all packets immediately then it safe to send
5973 any of subsequent packets through the queue, however, after
5974 the first packet is put to queue then any subsequent packets
5975 must also be put to the queue.
5977 Follow these rules and everything works fine.
5979 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added new function silc_server_remove_clients_by_server to
5982 remove all client entries from ID list when the server connection
5983 is lost. In this case it is also important to invalidate all
5984 client entires as they hold the invalid server entry. This
5985 fixes fatal bug when server has lost connection and will reconnect
5988 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Made some sanity checks to silc_server_daemonise like to check
5991 whether the requested user and group actually exists.
5993 * Added sanity check to SKE's silc_ske_responder_finish to check
5994 that the public and private key actually is valid.
5996 * Invalidate the client's nickname when receiving Replace ID
5997 packet and the Client ID is being replaced. This means that the
5998 server will query the nickname if someone needs it (client)
6001 * Sort the ID Cache in client library when the ID Cache data
6002 has changed (needs sorting).
6004 * Do not allow for SILC client to create several connections to
6005 several servers. The client does not support windows right now
6006 and generating multiple connections causes weird behaviour.
6008 Irssi-silc client does support windows and can handle several
6009 connections without problems, see: www.irssi.org and SILC plugin.
6011 * Fixed some places where client was added to the IDList. The
6012 rule of thumb is following (in order to get everything right):
6013 If the client is directly connected local client then the
6014 `connection' argument must be set and `router' argument must be
6015 NULL to silc_idlist_add_client function. If the client is not
6016 directly connected client then the `router' argument must
6017 bet set and the `connection' argument must be NULL to the
6018 silc_idlist_add_client function.
6020 * The funtion silc_server_packet_send_local_channel actually did
6021 not check whether the client was locally connected or not. It
6022 does that now. Fixed a bug related to LEAVE command.
6024 * Fixed Remove Channel User payload parsing bug in server's
6025 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6027 * The server's silc_server_save_channel_key now checks also the
6028 global ID list for the channel as it might not be in the local
6029 list. Fixed a bug related to LEAVE command.
6031 * Is this the end of the [<unknown>] buglet that has been lurking
6032 around for a long time? A little for loop fix in server's
6033 silc_server_command_whois_parse that is used by both IDENTIFY
6034 and WHOIS command. At least, this was a clear bug and a cause
6035 of one type of [<unknown>] buglet.
6037 * WHOIS and IDENTIFY commands call the function
6038 silc_server_command_[whois/identify]_check function even if
6039 we are not router server.
6041 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added --with-gmp configuration option. If set the GMP
6044 is always compiled in the SILC source tree. If not set then
6045 it is checked whether the system has the GMP3 installed. If
6046 it has then the GMP won't be compiled (the system's headers
6047 and library is used), if it doesn't have it then the GMP is
6048 compiled in the SILC source tree.
6050 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Changed RSA private exponent generation to what PKCS #1
6053 suggests. We try to find the smallest possible d by doing
6054 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6055 not security fix but optimization.
6057 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added new config entry [Identity] to fork the server and run
6060 it as specific user and group. A patch from Bostik.
6062 * Imported Dotconf configuration library into lib/dotconf.
6063 This will be used to create the SILC configuration files later.
6064 It will appear in the distsribution after this commit.
6066 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * A big code auditing weekend happening. Auditing code for
6069 obvious mistakes, bugs and errors. Also, removing any code
6072 Removed files for being obsolete:
6074 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6075 inline in the file lib/silcutil/silcbuffer.h)
6077 o lib/silcutil/silcbufutil.c (the header has inline versions)
6079 Changed code to fix possible error conditions:
6081 o The buffer formatting routines now check that the destination
6082 buffer really has enough space to add the data. This applies for
6083 both buffer formatting and unformatting
6084 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6085 unformatting was changed to accomodate following rules:
6086 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6087 sent to the function while XXX_*STRING will not allocate or copy
6088 the data into the buffer. Instead it sets the pointer from the
6089 buffer into the pointer sent as argument (XXX_*STRING used to
6090 require that the pointer must be allocated already). This change
6091 makes this whole thing a bit more consistent and more optimized
6092 (note that the data returned in the unformatting with XXX_*STRING
6093 must not be freed now). The routines return now -1 on error.
6095 o Tried to find all code that use buffer_format and buffer_unformat
6096 and added return value checking to prevent formatting and
6097 especially unformatting errors and possible subsequent fatal
6100 o Changed ske->x and ske->KEY to mallocated pointers in
6101 lib/silcske/silcske.h. Fixed possible data and memory leak.
6103 o Added return value checking to all *_parse* functions. Fixed
6104 many memory leaks as well.
6106 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6107 so that buffer overflows would not happen. All code now also
6108 checks the return value as it can fail.
6110 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added reconnection support to server if the normal server looses
6113 its connection to the router (for example if router is rebooted).
6114 The server performs normal reconnection strategy implemented
6115 to the server. Affected file silcd/server.c.
6117 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Added new packet type SILC_PACKET_SET_MODE that is used to
6120 distribute the information about changed modes (for clients,
6121 channels and clients channel modes) to all routers in the
6122 network. Updated the protocol specification accordingly.
6124 Added functions into silcd/packet_send.c and
6125 silcd/packet_receive.c: silc_server_send_set_mode,
6126 silc_server_set_mode.
6128 Added new files silcmode.[ch] into lib/silccore that implements
6129 the encoding and decoding of Set Mode Payload. Added new type
6130 SilcSetModePayload. Moved the definitions of different modes
6131 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6133 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Oops, a little mistake in server's connection authentication
6136 protocol. The protocol is not ended with FAILURE but with
6137 SUCCESS if the authentication is Ok. :) Affected file is
6140 * Implemented NICK_CHANGE notify handling in server in the file
6141 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6142 the local clients on the channel. After the changing nickname
6143 in router environment snhould work and the [<unknown>] nickname
6144 should appear no more.
6146 The silc_server_replace_id function that receives the Replace ID
6147 payload now sends the NICK_CHANGE notify type also in the file
6148 silcd/packet_receive.c
6150 * Changed WHOIS and IDENTIFY command to support the maximum amount
6151 of arguments defined in protocol specs (3328 arguments). This
6152 fixed a bug that caused problems when there were more than three
6155 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Added extra parameter, command identifier, to the
6158 silc_client_send_command so that explicit command identifier
6161 Changed that ID list routines uses specific command identifier
6162 when sending WHOIS/IDENTIFY requests to the server so that they
6163 can be identified when the reply comes back.
6165 Affected files lib/silcclient/command.[ch],
6166 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6168 * Added `sender' argument to silc_server_packet_send_to_channel
6169 to indicaet the sender who originally sent the packet to us
6170 that we are now re-sending. Ignored if NULL. Affected file
6171 silcd/packet_send.[ch].
6173 * Added some server statistics support in silcd/server_internal.h
6174 SilcServerStatistics structure and around the server code. Also
6175 send some nice statistics information when client is connecting
6178 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Fixed channel ID decoding in server's JOIN command reply in
6181 silcd/command_reply.c
6183 * Fixed braodcasting of replace ID payload to not to send it if
6184 we are standalone server in silcd/packet_receive.c.
6186 * Fixed all channel message sending routines to not to send
6187 packets to clients that has router set, since they are routed
6188 separately in the same function earlier. Affects file
6189 silcd/packet_send.c and all channel packet sending functions.
6191 * In USERS reply, res_argv[i] are not allocated, the table
6192 is allocated. Thus changed that free the table, not its
6195 * In server's whois_check and identify_check if the client is
6196 locally connected do not send any WHOIS commands - they are not
6199 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Fixed some minor bugs in client when sending WHOIS command. The
6202 arguments was in wrong order.
6204 * Removed statis function add_to_channel from server in
6205 silcd/command.c that was previously used with the joining but
6208 * Tested USERS command in router environment successfully with two
6209 routers, two servers and two clients.
6211 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Reorganized the USERS command and command reply in client library
6214 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6215 When the command is given by user we register a pending command
6216 callback that will reprocess the command after the reply has been
6217 received from the server. When reprocessing the packet we then
6218 display the information. Thus, the USERS information is displayed
6219 now in the command callback instead of in the command reply
6220 callback. The processing of the command is same as previously
6221 when server has sent the command reply in the JOINing process.
6223 * Added to USERS command in silcd/command_reply.c to join the client,
6224 we didn't use to know about, to the channel after we've created
6225 a client entry for it. Also, for clienet we did know already still
6226 check whether it is on the channel or not and add it if not.
6228 * Removed silc_server_command_join_notify as the function and its
6231 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Changed the client's pending command handling to the same as the
6234 server's pending command handling. It is also now possible to
6235 execute command reply functions from other command reply
6236 function as the function callbacks for commands and command
6237 replies are one and same. The pending commands are not static
6238 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6239 in client connection context. Thus, pending commands are server
6240 connection specific as it is convenient.
6242 Changed the function silc_client_command_pending and
6243 silc_client_command_pending_del and added new function
6244 silc_client_command_pending_check. Removed the
6245 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6248 * Added cmd_ident, current command identifier, to the client
6249 connection context in lib/silcclient/client.h to keep track on
6250 command identifiers used in command sending. Client's command reply
6251 function handling now supports the mandatory command identifiers.
6253 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6254 funtions in client to fully support pending command callbacks.
6256 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6257 as one of the arguments to the application in the command reply
6260 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6261 before first releasing SILC but came back. Now it is removed again
6262 and should come back nomore. The FORWARDED flag was used only
6263 by the JOINing procedure by forwarding the command packet to router.
6264 Now, the JOINing procedure has been changed to more generic (due
6265 to various router environment issues) and FORWARDED is not needed
6266 anymore for anything. The protocol specification is yet to be
6269 Now, removed silc_server_packet_forward from server and the flag
6270 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6272 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Renamed NAMES command to USERS command. The NAMES was named that
6275 due to historical reasons. Now it is renamed. Also, rewrote
6276 parts of the USERS command. The nickname list is not sent anymore
6277 by the server. Only Client ID and mode lists are sent in the USERS
6278 command. Changed this also to the protocol specification.
6280 The client now resolves the names and stuff after it receives
6281 the USERS list from the server when joining to the channel.
6283 * WHOIS and IDENTIFY commands has been changed to support multiple
6284 Client ID's per command. One can now search for multiple users
6285 in the network by sending only one WHOIS or IDENTIFY command.
6286 Changed the code and the protocol specifications.
6288 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6289 uses silc_server_command_whois_parse to parse the request. */
6291 * If normal server, do not parse the WHOIS and IDENTIFY requests
6292 before sending it to the router. Saves some time.
6294 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Fixed JOIN command on client library. Wrong number of arguments
6297 used to crash the client.
6299 * Added silc_server_channel_has_global function to check whether
6300 channel has global users or not.
6302 * Added silc_server_channel_has_local function to check whether channel
6303 has locally connected clients on the channel.
6305 * The silc_server_remove_from_one_channel now checks whether the
6306 channel has global users or not after given client was removed from
6307 the channel. It also checks whether the channel has local clients
6308 on the channel anymore. If it does not have then the channel entry
6309 is removed as it is not needed anymore.
6311 * The silc_server_notify now checks on JOIN notify whether the joining
6312 client is one of locally connected or global. If it is global then
6313 the channel has now global users on the channel and that is marked
6314 to the channel entry. Also, it now saves the global client to
6315 global list who is joining and JOINs it to the channel. This is
6316 for normal server, that is.
6318 Changed silc_server_send_notify_on_channel,
6319 silc_server_packet_relay_to_channel and
6320 silc_server_packet_send_to_channel check if we are normal server
6321 and client has router set (ie. global client) do not send the
6322 message to that client, as it is already routed to our router.
6324 * Implemented LEAVE notify type handling in silc_server_notify
6327 * Tested LEAVE command in router environment successfully. Tested
6328 with two routers, two servers and two clients.
6332 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6334 * Implemented SIGNOFF notify type handling in silc_server_notify
6337 * silc_server_remove_id now removes the client entry from all channels
6338 it has joined and thusly sends SIGNOFF notify type.
6340 * Rewrote the NAMES list generation in server by removing two excess
6341 loops. The lists are created now inside one loop.
6343 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * silc_server_remove_channel_user checks now also global list
6346 for channel and client.
6348 * silc_server_new_channel_user checks now both local and global
6349 list for channel and client. Fixed a bug in client id decoding.
6350 Used to decode wrong buffer.
6352 * silc_server_channel_message checks now both local and global
6353 list for channel entry.
6355 * Tested channel joining (hence JOIN) in router environment
6356 successfully. Tested with two routers, two servers and two
6359 * Tested channel message sending in router environment successfully.
6361 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Added silc_server_save_channel_key into server.[ch] to save the
6364 received channel key in Channel Key payload processing. It is
6365 also used in JOIN command reply handling.
6367 Equivalent function silc_client_save_channel_key added into
6368 client.[ch] into client library.
6370 * Changed JOIN command reply to send information whether the channel
6371 was created or not (is existing already) and the channel key
6372 payload. Changed protocol specs accordingly.
6374 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6375 the request was sent by ID and not by nickname. Crashed on
6378 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6381 now correctly save the received data.
6383 * silc_server_free_sock_user_data now notifies routers in the
6384 network about entities leaving the network.
6386 At the same time implemented functions silc_server_remove_id
6387 and silc_server_send_remove_id to receive and send REMOVE_ID
6388 packets. The packet is used to notify routers in the network
6389 about leaving entities. The ID removed will become invalid in
6392 * Added function silc_idlist_del_server into server. Removes and
6393 free's server entry from ID list.
6395 * silc_server_private_message function now checks, if we are router,
6396 that the destination ID really is valid ID, naturally.
6398 * In router when NEW_ID packet is received (for new client) the
6399 hash of the Client ID is saved in the ID Cache but the
6400 client->nickname is set to NULL, instead of putting the hash
6403 IDENTIFY command now also checks that client->nickname must be
6404 valid. If it is not if will request the data from the server who
6405 owns the client. Added new function
6406 silc_server_command_identify_check.
6408 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6409 to set the command to already allocated Command Payload.
6411 * Tested private message sending in router environment with two
6412 routers, two servers and two clients. Fixed minor bugs and now
6415 * Fixed segfault from client's NAMES command. Used to crash if
6418 * Forwarded packets must not be routed even if it is not destined
6419 to the receiver. Changed server code comply with this.
6421 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added `require_reverse_mapping' boolean value to ServerParams
6424 structure. If TRUE (not default) the server will require that
6425 the connecting host has fully qualified domain name.
6427 If the reverse mapping is not required and hostname could not be
6428 found the IP address is used as hostname.
6430 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Implemented version string checking to both client and server.
6433 The check is incomplete currently due to the abnormal version
6434 strings used in development version of SILC.
6436 * Changed all command functions in server to use the new
6439 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Changed char *data to unsigned char *data in ID Cache system to
6442 support binary data as ID Cache data. Changed code to support
6443 binary data in lib/silccore/idcache.c.
6445 * Renamed silc_server_packet_relay_command_reply to
6446 silc_server_command_reply as it is normal packet receiving
6447 function. Rewrote the function to accept command replys for
6448 servers and not only for clients.
6450 * Mark remote router always as registered server if we are connecting
6451 to it. Otherwise, commands sent by the router to us are ignored.
6453 * All ID List find routines now returns the ID Cache Entry pointer
6454 as well if requested.
6456 * WHOIS command works now in router environment, tested with two
6457 routers, two servers and two clients.
6459 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6460 in router environment (as it is almost equivalent to WHOIS) but
6461 hasn't been tested thoroughly. Added new functions:
6463 silc_server_command_identify_parse
6464 silc_server_command_identify_send_reply
6465 silc_server_command_identify_from_client
6466 silc_server_command_identify_from_server
6468 * Disabled route cache adding because adding two different ID's with
6469 same IP replaces the old cache entry thus giving wrong route.
6470 The entry->router->connection is always the fastest route anyway
6471 so route cache may not be needed. Of course, new routes maybe
6472 established after receiving the ID when the entry->router->connection
6473 might not be anymore the most optimal.
6475 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Add route cache for received ID for fast routing.
6479 * Added silc_server_packet_route to route received packet on router
6480 that is not destined to us.
6482 * Renamed silc_server_get_route to silc_server_route_get.
6484 * Added id_string and id_string_len fields into SilcServer to
6485 include encoded ServerID for fast comparing without excess
6486 encoding of the ID's.
6488 * Cleaned up WHOIS command on server side. Added following static
6491 silc_server_command_whois_parse
6492 silc_server_command_whois_check
6493 silc_server_command_whois_send_reply
6494 silc_server_command_whois_from_client
6495 silc_server_command_whois_from_server
6497 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6498 arguments in command replies. All command functions should be
6499 updated to use this macro.
6501 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Minor typo fixes on command reply handling on server.
6505 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Added silc_server_command_add_to_channel internal routine to add
6508 the client to the channel after router has created the channel and
6509 sent command reply to the server.
6511 * Added generic silc_server_send_command to send any command from
6514 * Use static buffer with ID rendering instead of duplicating data.
6516 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Fixed a channel user mode bug when joining to a channel server gave
6519 everybody channel founder rights, oops.
6521 * We mark ourselves as the router of the incoming server connection
6522 if we are router ourselves. This way we can check in some packet
6523 sending functions whether it is locally connected server. For
6524 incoming router connections we put NULL.
6526 * For router sending packets locally means now always sending the
6527 packet cell wide; to local clients and local servers. For normal
6528 server sending packet locally means sending it to only local
6531 * Fixed the JOIN command to really work in router environment. If the
6532 channel is created it is always created by the router. Router is
6533 also responsible of making the initial joining to the channel,
6534 sending JOIN notify to the sending server and distributing
6535 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6536 does not exist server doesn't do anything else but forward the
6537 command to the router which performs everything.
6539 * Added silc_server_send_channel_key function to send the Channel Key
6542 * Added silc_server_create_channel_key to create new channel key. The
6543 channel key is now re-generated everytime someone joins or leaves
6544 a channel, as protocol dictates. Note: channel->key_len is the
6547 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6550 packet_receive.[ch] to separate packet sending and receiving
6551 routines. The server.[ch] now includes everything else including
6552 actual packet processing (writing and reading data) and other
6555 Renamed silc_server_private_message_send_internal to
6556 silc_server_send_private_message. The routine is still though
6557 used only to relay private messages as server does not send
6558 private messages itself.
6560 Renamed silc_server_new_channel to silc_server_create_new_channel
6561 and added new function sicl_server_new_channel that handles the
6562 incoming New Channel packet. Added also new sending function
6563 silc_server_send_new_channel to send New Channel Payload.
6565 * Added new function silc_server_notify to process incoming notify
6566 packet to the server/router. Server may then relay the notify
6567 to clients if needed.
6569 * Added new function silc_server_new_channel_user to process incoming
6570 New Channel User packet. Router will redistribute the packet and
6571 send JOIN notify to its local clients and locally connected servers
6572 if needed. Normal server will send JOIN notify to its local client
6573 on same channel when received this packet. Added also corresponding
6574 sending function silc_server_send_new_channel_user to sent the
6577 * Added boolean route argument to send_notif_to_channel and
6578 packet_send_to_channel functions to attempt to route the packet
6579 if it is TRUE and send only locally if it is FALSE.
6581 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * silc_server_replace_id now broadcasts the received replace ID
6584 packet if it is not broadcast packet already. The router must
6585 broadcast to inform other routers about changed ID.
6587 * Added backpointer to server's router into SilcServer context in
6588 silcd/server_internal.h.
6590 * Fixed silc_server_packet_broadcast to send correct broadcast
6593 * The channel key is now distributed to the local client as soon
6594 as it is received from the router (in router environment) so that
6595 no other packet may be sent for the channel until client has
6598 * silc_server_remove_channel_user now broadcasts the received
6599 Remove Channel User packet if it is not broadcast packet already.
6600 The router must broadcast to inform other routers about removed
6603 * Added users field into SilcPacketContext that is a reference count
6604 of the context. One can increase the reference count by calling
6605 silc_packet_context_dup which is now changed to just increase the
6606 reference count instead of duplicating the data. The reference
6607 count is decresed by calling silc_packet_context_free that will
6608 free the data after the reference count hits zero.
6610 For now on the packet context and everything allocated into it
6611 (including the raw packet from network) must be freed by calling
6612 the new silc_packet_context_free function. Added also new function
6613 silc_packet_context_alloc that must be used now to allocate the
6614 context. This also means that if a routine is asynchronous from
6615 silc_[client/server]_packet_parse_type the packet context must
6616 be duplicated by calling silc_packet_context_dup. Otherwise it
6617 gets free'd after silc_[client/server]_packet_parse_type returns.
6618 Also, one must remember that if packet is duplicated then its
6619 reference count must be decresed by calling the free function as
6620 many times as it was duplicated.
6622 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6623 from both client and server.
6625 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Made joining to a channel working in router environment.
6629 * Cleaned up JOIN command on server side and create function
6630 silc_server_command_join_channel internal routine to make the
6633 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6635 * Changed silc_command_pending list to SilcDList. Also, added
6636 `ident' field to SilcServerCommandPending structure to identify
6637 the reply and to call correct callback.
6639 Added silc_server_command_pending_check function to replace the
6640 corresnponding macro. The silc_command_pending list is not
6643 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6644 to set identifier to previously allocated Command Payload. It
6645 is used to set identifier for command when resending Command
6648 * Added silc_command_payload_encode_payload to encode Command
6649 Payload buffer from SilcCommandPayload structure.
6651 * Added silc_argument_payload_encode_payload to encode Argument
6652 payload buffer from SilcArgumentPayload structure.
6654 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Changed WHOIS command to support router connection on server side.
6657 The whois request is always sent to router unless the server is
6658 standalone server. After server has received the reply from the
6659 router will it send the reply to the client.
6661 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6662 broadcast received broadcast packet. The function is used only
6663 by router. The broadcast packet is always sent to the router's
6666 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6667 render given ID to printable string, for log files for example.
6669 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Made basic router to router connections working. At least they
6672 can now connect to each other but nothing really works the way
6673 they are supposed - yet.
6675 * Added new initiator token to RouterConnection configuration
6676 file in silcd/serverconfig.[ch]. It is used to tell whether we
6677 are the initiator to the remote router or whether we'll expect
6678 the other end to connect.
6680 * Moved registering of listener task to silc_server_init, hence
6681 the server starts listenning as soon as it is run, even if it
6682 does not have connections to other routers. Let's see how well
6685 * Changed default connection retry timeouts for more suitable in
6688 * Removed cipher and such arguments from silc_idlist_add_client
6689 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6690 Added new function silc_idlist_add_data to add the keys and stuff
6693 * Added SilcIDListData structure and added it to SilcClientEntry
6694 and SilcServerEntry as their first field in the structure. This
6695 way we can explicitly cast the ID entries to the SilcIDListData
6696 structure and get common data for the entries. In past, we had
6697 to first check what type of connection it is and then cast it to
6698 correct ID entry type. Now, we can directly cast the opaque
6699 pointer to the SilcIDListData (no matter what ID entry it actually
6700 is) and get the data needed.
6702 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6705 in some circumstances even if threre were timeout tasks, though not
6706 IO tasks, but tasks anyway. Now fixed.
6708 * Defined SilcServerConnection structure to hold connection specific
6709 stuff about directly connected servers and routers. The definition
6710 is currently in silcd/server_internal.h. I thought about having
6711 a bit more important role fro this struct but for now it is used
6712 only when connecting to other server (or router actually).
6714 * Added connecting retry support in server when connecting to
6715 router(s). The retry feature implement exponential backoff
6716 algorithm. Also, added SilcServerParams structure to hold default
6717 parameters for server. For now, it include these retry settings
6718 and are hard coded. After server is moded to be as Silc Server
6719 Library this structure will be more important.
6721 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Changed client librarys channel->clients table to SilcList and
6724 changed code accordingly.
6726 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Changed client's channel table to SilcList and changed code
6729 accordingly. Also changed SilcChannelClientEntry to include back-
6730 pointer to the channel so that client entry can use that structure
6731 as list as well and we have fast cross-reference to the channel.
6732 This change dramatically decreased the complexity of channel
6733 handling with client entry and vice versa (removed one extra
6734 loop when searching for channel entry from many functions).
6736 * Changed server->sim from table to SilcDList and changed code
6739 * NAMES command can now be used from user interface. It will show
6740 the user list on the channel, neatly.
6742 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6743 Code now saves realname of the user if it becomes available.
6745 * Renamed configure.in to configure.in.pre and made ./prepare
6746 script to automatically add correct version string to
6747 configure.in which it creates from configure.in.pre.
6749 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6751 * NAMES command reply now shows users mode with the nickname when
6754 * Moved silc_client_ch[u]mode[_char] functions from
6755 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6756 place sucks, they are utility functions and should be in some
6759 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6761 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6764 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Added TRQ (efficient deque and list library) into lib/trq. This is
6769 a very good list library that is currently used in the SILC. Defined
6770 SilcList API over the library because I didn't like the API very
6771 much. See lib/trq/silclist.h for the API and examples of how to
6772 use the API. Fixed various places in the code to use the new
6773 SilcList API. The SilcList is meant for lists that has a structure
6774 already defined as a list. It is not suitable to add just some
6775 context to the list (in TRQ, the context is the list actually).
6777 So, I defined SilcDList that can be used for the purpose where
6778 predefined list structure does not exit. This can be used as
6779 such list. Now some context just can be added to the SilcDList.
6780 Currently this list is not used in the SILC just yet, though there
6781 are a lot places where this can replace dynamically allocated
6782 tables and I will fix these places, later, to use SilcDList.
6783 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6784 and use TRQ internally).
6786 Also fixed some annoying warning messages that the original TRQ
6787 code generated. Also minor changes to TRQ's Makefile.in.
6789 * Added support for querying by Client ID to both WHOIS and
6790 IDENTIFY commands into server, as required by the protocol.
6792 * Removed method function pointers from SilcBuffer structure. They
6793 weren't used to anything and just increased the context size for
6794 no good reason. This change also made silc_buffer_alloc and
6795 silc_buffer_free functions inline functions.
6797 * Disabled command flooding detection support until it's fixed so
6798 that it accepts commands in but does not execute them more than once
6801 * Added silc_net_localhost(), to return local hostname, into
6802 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6803 that must be initialized before calling silc_client_init.
6805 * Added new function: silc_server_send_notify_on_channels to send
6806 notify messages to all channels client has joined. It is assured
6807 that the message is sent only once per client.
6809 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6810 lib/silcutil/silcutil.[ch] as silc_format function. The new
6811 function is generic and is used by server as well, not only by
6812 the logging routines.
6814 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6815 the provided version string was not acceptable. Added new function:
6816 silc_ske_check_version into lib/silcske/silcske.h. The function
6817 must be implemented by the application (client or server) and it
6818 does not reside in the SKE library. The function checks the version
6819 string remote end sent.
6821 * Added back pointers (to opaque context and to SilcSocketConnection)
6822 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6824 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6825 duplicate packet context structure.
6827 * Changed `notify' client operation to send same arguments as client
6828 receives from server except for ID's. ID's are mapped to correct
6829 ID entry and that is returned. Also, if channel entry is not sent
6830 by server but the notify is for channel the channel entry is sent
6831 to application (otherwise application doesn't know that it is for
6832 channel (library gets it from packet's Destination ID)).
6834 * Added silc_client_remove_from_channels into client library to
6835 remove a client from all channels it has joined to. Used when
6836 received SIGNOFF notify from server. Added also new function
6837 silc_client_replace_from_channels to replace old ID entry with
6838 new ID entry on all channels. Used when received NICK_CHANGE
6841 * Fixed ID Cache list handling in silc_idlist_get_client in
6842 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6843 to get (or query) client by ID.
6845 * Updated TODO list.
6847 * Added connection authentication status message defined by the
6848 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6849 support for these into the code in client and server side.
6851 * Added generic function silc_client_send_command to send any command
6852 with variable argument list. Application should use this function
6853 to send commands if the command functions provided by the library
6854 does not suite for the application's user interface needs.
6856 * Added new `failure' client operation. Application is notified about
6857 received failure packet if client is executing a protocol. In this
6858 case the protocol's execution has failed.
6860 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6861 is required by the protocol.
6863 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6864 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6867 * Added status flag to SilcSKE object to indicate realtime status
6868 of the SKE protocol.
6870 * Application receives now exactly same command reply arguments as
6871 the library receives from server. However, if ID is received the
6872 corresponding ID entry is returned to the application (eg. Client
6873 ID is mapped to correct SilcClientEntry entry and that is returned).
6874 Changed command_reply client operation due to this change.
6876 * Changed all ID's in commands and in command replys as ID Payloads.
6877 Change affected both client and server side codes.
6879 All ID's sent in SILC network (with execption of ID's in SILC
6880 Packet header) are sent in ID Payload to support variable length
6883 * Server now notifies nick changes and notifies all clients on
6884 the channels about the new nickname (about the new Client ID,
6887 * Implemented CMODE command to change channel modes. Supports all
6888 channel modes defined by the protocol specs except ban and invite
6889 lists. (Also, private channel key mode is supported but support for
6890 setting private channel key in client is missing, thus, this mode
6891 has no effect on client side (except that server requires that the
6892 client uses private channel key and normal channel traffic does not
6895 Also, invite mode works per se, but INVITE command does not work
6896 yet correctly, so you can set channel as invite only channel but
6897 inviting clients to the channel does not work (it is yet to be
6898 thought what's the best way to do it).
6900 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6901 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6902 Implemented CUMODE command to change user's mode on the channel.
6903 Supports all modes defined by the protocol specs.
6905 * Added NAMES command reply to return users modes on the channel.
6907 * Removed unnecessary and slow ciphers from lib/silccrypt.
6909 * Set SO_KEEPALIVE option to connection sockets by default.
6911 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6913 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6914 redefined the Notify Payload into protocol specs.
6916 * Added silc_id_payload_parse_id to get ID directly from raw
6919 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6922 accept searching by Client ID as well.
6924 * Added support for LEAVE and SIGNOFF notify types in client library.
6926 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6927 to parse ID Payload from raw data.
6929 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added flags parameter into silc_ske_assemble_security_properties
6932 function in lib/silcske/silcske.[ch].
6934 * Changed notify client operation to fit better for notify messages
6935 sent by server. The notify payload received from server is now
6936 passed to the application (after parsing it to SilcNotifyPayload).
6937 It is application's responsibility to retrieve the arguments
6938 from the payload and show the message the way it wants. The message
6939 sent by server is implementation specific.
6941 * Changed public keys to comply with the protocol specification.
6942 Old public keys are not supported anymore and are not compatible.
6944 * Removed nickname from Channel Payload as the latest draft removed
6945 it. The client must resolve the nickname from the NAMES command
6946 reply received when it joined the channel.
6948 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6950 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Fixed some errors in protocol specification drafts.
6954 * Created lib/silccore/silcnotify.c to implement Notify Payload
6955 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6956 generic payloads described by protocol specifications. The file
6957 includes implementations for ID Payload and Argument Payload.
6959 * Changed Command Payload implementation to use the new Argument
6960 Payload. Changed command_xxxx_payload to command_payload_xxxx
6961 to comply with SILC coding conventions.
6963 * Added suppport for Argument Payload handling in Notify Payload
6964 implementation as protocol requires it. Added the new support
6965 into server and client lib as well.
6967 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6969 * Added support for multiple nicknames on same channel. [n] is
6970 added locally to the nickname if there are more than one same
6971 nicknames on the channel.
6973 * Server now sends all nicknames that matched WHOIS request.
6974 Client also shows the list received from server.
6976 * Added TOPIC command to client side. User can now set and show
6977 current topic on channel.
6979 * Added MOTD command to client and server. Also, server sends the
6980 motd when client connects to the server.
6982 * Changed version strings to comply ISO 8601.
6984 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Fixed protocol error handling in client library. It should now
6987 cope even if the SKE fails for some reason.
6989 * Made new protocol specification drafts for submitting to IETF.
6991 * Implemented TOPIC command to server in silcd/command.c.
6993 * Added two new notify types into lib/silccore/silcnotify.h:
6994 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6995 notify nickname change and topic setting/change on a channel.
6997 * API change of command_reply operation in client library. The
6998 application gets now the status type received from server as well.
7000 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7004 * Cras fixed and optimized the packet handling even further and
7005 it should work now. Minor change to the prototype of function
7006 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7008 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Added new function into lib/silcutil/silcschedule.[ch]:
7011 silc_schedule_with_fd to select() a specified fd. The function
7012 returns after timeout expires or data arrives or goes. The
7013 function is used by packet routines to wait that all data is
7014 received from network.
7016 * Fixed data reading from network in lib/silccore/silcpacket.c.
7017 The code now assures that all data is read from the fd and then
7018 continues packet processing. This was a bug fix since the code
7019 used to drop some data in some circumstances.
7021 * Added new function into lib/silcclient/client.[ch]:
7022 silc_client_start_key_exchange to start key exchange after
7023 connection has been established to server. The code internally
7024 now uses this funtion but its main purpose was to provide it
7025 for applications that perform their own connecting. After
7026 application has created a connection it merely calls this
7027 function to start the key exchange between client and server.
7028 The library takes care of everything else after that.
7030 Updated also lib/silcclient/README to explain the usage of
7033 * Do not send to application information that connection has
7034 been established. Application gets notified it by connect
7037 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Applied cras's patch to add silc_schedule_one function. The
7040 function runs scheduler once and returns.
7042 * Fixed the scheduler after cras messed it up. The timeout
7043 handling works now as it's supposed to work.
7045 * Added into lib/silccore/ silcnotify.h to include notify
7046 message types support. Changed silc_server_send_notify*
7047 functions, in server.[ch], to support those new notify types.
7048 Added the support for the notify types into client library,
7049 as well. Added new notify client operation into ops.h in
7052 * Changed silc_server_packet_send_to_channel to send normal
7053 packets instead of just channel message packets. The function
7054 is now used to send the notify packets to channels. It is not
7055 used to send channel message packets anymore, as server never
7058 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7059 va_arg()s as it seems to require it nowadays. I guess, if SILC
7060 is compiled with older va_arg() the new code should work anyway.
7062 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Splitted core library. Core library (lib/silccore) includes
7065 now only SILC protocol specific core (and common) components.
7066 Created new utility library (lib/silcutil) that includes more
7067 generic purpose stuff. The stuff for util library was taken
7068 from the old core library. This was minor and easy split.
7070 * Created SILC Client Library (lib/silcclient) that includes
7071 implementation of the SILC client without user interface. This
7072 was major move from silc/ directory. The code has been changed
7073 so that it is transparent towards the user interface. The
7074 silc/ directory includes now the same user interface as before
7075 and it uses the new client library. Read lib/silcclient/README.
7076 Basicly, the client library performs everything else related
7077 to SILC except user interface handling. Also, configuration
7078 files are considered to be part of user interface and library
7079 does not handle them.
7081 This change also changed a lot of structures, function naming etc.
7082 Most important change was that SilcClientWindow object was
7083 renamed to SilcClientConnection in the client library. Created
7084 also new file lib/silcclient/ops.h. Also added new files
7085 silc/local_command.[ch] and silc/client_ops.[ch].
7087 All these changes were made to make it easier for user interface
7088 designers to create what ever user interface for the SILC client
7091 It is also expected that the server will be moved to lib
7092 directory as well and SILC Server Library will be created;
7093 sometimes in the future.
7095 * Removed Local commands from lib/silccore/silccommand.h as
7096 they are application specific and new client library does not
7097 handle any of those anymore.
7099 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7100 old client implementation in silc/.
7102 * Added support for callback functions in SILC_LOG_* macros.
7103 Application can now set its own callbacks that will be called
7104 instead of using the default functions that will always print
7105 the debug messages to stderr (or stdout). Also, debugging can
7106 now be disabled by setting silc_debug to FALSE and re-enabled by
7107 setting it to TRUE. Note, that logging will still work even
7108 if debugging is disabled.
7110 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7111 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7112 silc_log_reset_debug_callbacks.
7114 * To enable debugging in silc client one must give now -d
7115 option on command line.
7117 * Changed silc_schedule_init to automatically allocate task queues
7118 if they are not allocated before calling it.
7120 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Added GMP 3.1 into math library.
7124 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7127 a channel in SILC network. The packet is used by servers and
7128 routers to notify other routers that user has left a channel.
7129 This little feature was missing until now. Added the feature
7130 to protocol specification as well.
7132 Added functions: silc_server_send_remove_channel_user and
7133 silc_server_remove_channel_user into server.[ch].
7135 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7136 lib/silccore/silcpacket.h. However, they are not implemented
7139 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Fixed joining to a channel and sending channel messages
7142 between server and router. The channel message sending should
7143 now work inside a cell.
7145 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * Fixed the private message sending between server and router.
7148 The private message sending should now work inside a cell.
7150 * Added silc_server_replace_id into server.[ch] to replace
7151 existing ID in the SILC network.
7153 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7154 and silc_idlist_replace_server_id into idlist.[ch] in server.
7156 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Fixed the server to server connections. Server can again now
7159 connect to router. Router to router connections probably does
7162 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Added dynamic protocol registering support. Now protocols can
7165 registered and unregistered on the fly. Patch by cras.
7167 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7169 * Added lib/contrib directory to hold routines that some platforms
7170 don't have but are needed by SILC.
7172 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7173 into lin/contrib to provide getopt() and getopt_long() for
7174 those who don't have it.
7176 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added AWAY command to client. When away message is set and
7179 client receives a private message packet the client automatically
7180 replies to the sender with the away message.
7182 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7183 bug seemed to be the cause of recent problems when compiling
7186 * Added version detection support to SKE protocol specification
7187 and added the new changes to the SKE implementation as well.
7188 There were other minor changes in the SKE protocol as well.
7190 Many changes in lib/silcske/silcske.[ch] and in
7191 lib/silcske/payload.[ch].
7193 * Added ^U functionality, clear input line. Patch from cras.
7195 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Mainly small bugfixes on core library. Fixed some debugging
7198 logging and buffer overflow in silclog.c.
7200 * Updated config.sub and config.guess on the distribution tree.
7202 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Added command lagging support in server. Client may execute
7205 commands now only once in two seconds.
7207 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * Optimized packet reception. MAC computation and checking is now
7210 also more optimized. A lot previously duplicated code is now
7211 used as generic by both client and server.
7213 * Fixed key pair generation in clientutil.c
7215 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Added into lib/silccore/silcbufutil.[ch] new function;
7218 silc_buffer_realloc.
7220 * Moved generic packet sending/encryption functions to
7221 lib/silccore/silcpacket.[ch] from client and server. Some
7222 rewriting of the functions.
7224 * Moved all generic packet reception/decryption functions to
7225 lib/silccore/silcpacket.[ch] from client and server. The
7226 packet processing is now much cleaner in both client and server.
7227 These were major changes in both client and server.
7229 * Created many common functions in server to do packet sending.
7230 Previously code were duplicated a lot, this has been removed
7233 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Rewrote major parts of the ID cache system. Don't know
7236 whether it is better now or not but at least the API is more
7239 * Major rewrite on ID cache stuff on client because of the ID
7240 cache API changes. Added idlist.c to client.
7242 * Also major rewrite on ID cache stuff on server as well.
7243 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7244 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7245 in hand, instead they are all put into the ID cache system now.
7246 All server_idlist_* routines uses ID cache now instead of
7247 traversing its own lists (those lists does not exist anymore).
7248 SilcIDList though still exists. Also, SilcXXXEntry's are
7251 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * Finally made the SKE implementation compliant to the protocol
7254 specification. All mp integers are now binary encoded as
7255 opposed being HEX encoded.
7257 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7260 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7261 functions: silc_[encode/decode]_pem. Also added function
7262 silc_encode_pem_file to PEM encode with newlines ('\n') for
7265 * SILC public keys are now encoded either PEM or binary. Same
7266 option is for private keys as well. By default private keys
7267 are binary encoded and public keys PEM encoded. Silly HEX
7268 encoding were removed.
7270 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7271 function to create fingerprints.
7273 * Fixed a bug in SHA1; does not change the original data anymore.
7275 * Partly implemented INFO command on client and server side.
7276 Fixed CLEAR command. Changes to SERVER command; show current
7277 server(s) when giving command without arguments. Added
7278 VERSION command to client.
7280 * Added check to server that unregistered connections cannot
7281 execute commands (unless it is specificly allowed).
7283 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Fixed screen refresh.
7287 * Fixed channel joining bug from client. On some circumstances
7288 client tried to join to a channel it had already joined.
7290 * Added public key verification process into client's protocol.c.
7291 The client now verifies the public key from user and saves
7292 it into ~./silc/serverkeys/ directory.
7294 Added into: clientutil.[ch]: silc_client_verify_server_key.
7296 * Changed SKE protocol's silc_ske_initiator_finish function
7297 to accept callback function that verifies the received public
7298 key. Removed old silc_ske_verify_public_key function.
7300 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7302 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7303 silc_pkcs_private_key[_data]_set.
7305 * Made the password and public authentication more cleaner in
7306 server's protocol.c.
7308 * Removed historic and obsolete protocol `channel_auth' from
7309 both client and server.
7311 * Removed wrong way of sending command status messages from
7312 server to client in server's command.c. The old way violated
7313 protocol specification.
7315 Changes to silccore/silccommand.[ch]: removed
7316 silc_command_encode_status_payload -> not needed anymore,
7317 changed silc_command_encode_payload_va to accept extra
7318 argument on variable argument list. The argument type must
7319 now be provided to the function. Also, added new function:
7320 silc_command_encode_reply_payload_va which is same as
7321 normal command_encode_payload_va except command status type
7322 is provided as extra argument.
7324 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added ~./silc directory handling. The directory includes the
7327 public and private keys for the client.
7329 Added silc_client_check_silc_dir, silc_client_create_identifier
7330 and silc_client_load_keys.
7332 * Implemented SILC protocol compliant public key. Added public
7333 and private key saving to and loading from files.
7335 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7336 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7337 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7338 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7339 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7341 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7342 silc_pkcs_load_[public/private]_key.
7344 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Added silc_server_get_route (route.[ch]) to get connection
7347 data for the fastest route for given ID.
7349 * Implemented INVITE command on client and server. The command
7350 were re-defined in the SILC Protocol Specification and the
7351 implementation now complies with the specification.
7353 * Implemented PING command on client and server.
7355 * Implemented NAMES command on client and server. The server side
7356 supports currently only normal server not router server yet.
7357 Some changes to NAMES definition in SILC protocol specification.
7359 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Implemented LEAVE command on client and server.
7363 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7364 again. This change was made to the protocol as well. Server
7365 should not violate the protocol specification anymore.
7367 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7369 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7370 was tested. SOCKS4 was not but should work anyway.
