24 directions. Affected file silcd/packet_receice.c.
26 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
28 * Delete the client from channel even if the cilent->id is
29 NULL. It was possible that client was deleted without

41 to the primary router connection, the other one returns
42 TRUE if packet must be broadcasted to network.
44 * All notifys that are destined to primary router (to network)
45 are now automatically sent to backup routers even if the
46 router is standalone (and has backup router). Affected files
49 * Added --without-irssi and --without-silcd configuration
50 options for disabling the compilation of these applications.
51 Affected file configure.in.pre and prepare.

92 Router announces stuff only after server reannounces channel
93 after CHANNEL_CHANGE notify.
95 These fixes optimizes the announcing procedure, and perhaps
96 fixes some problems too. Affected file silcd/packet_receive.c.
98 * Fixed SERVER_SIGNOFF sending to local clients. It was
99 totally broken and sent the notify to all local clients,
100 instead of only to those that was on same channel as the
101 signing off clients. Affected file silcd/server_util.c.
103 * Added -D option to server. It can be used to give debug
104 level. The levels are from 0 - 99, and are predefined for
105 smooth server debugging. (see silcd.c for the predefined
106 levels). Affected file silcd/server.c.
108 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

551 * Added SilcStatus argument to `command' client operation
552 to return the error status when command sending fails
553 locally. Changed all command in client library to return
554 correct command status. Affected files are
555 lib/silcclient/command.c, lib/silcclient/silcclient.h and
556 irssi/src/silc/core/client_ops.c.
558 Thu Apr 18 14:09:51 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
560 * Added silc_mime_parse function to parse MIME headers.
561 Affected files are lib/silcutil/silcstruti.[ch].
563 * Added MIME header parsing in Irssi SILC Client. It displays
564 all textual MIME objects, others it ignores. Affected file
565 is irssi/src/silc/core/clien_ops.c.
567 Wed Apr 17 22:07:59 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
569 * Fixed a bug in the pid writing function, which couldn't be
570 written in a root-owned directory.
572 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Defined that channel message to unknown Channel ID must
575 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
576 Updated the protocol specs and the code in server. The
577 affected file is silcd/packet_receive.c.
579 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
582 that it is used to send error notifys if error occurs during
583 some SILC packet processing, except commands. The error
584 types are same as for command reply types. Defined that
585 if private message is sent to unknown Client ID the error
586 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
587 Updated the protocol specs and code. Affected files are
588 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
589 lib/silcclient/client_notify.c, silcd/packet_receive.c,
590 and irssi/src/silc/core/client_ops.c. Renamed the
591 SilcCommandStatus to SilcStatus.
593 * Defined the use of extra WHOIS attributes in WHOIS command.
594 The <Requested Attributes> (defined in a separate document)
595 can be used to request additional information about user
596 not returned by standard WHOIS command. Defined that server
597 can send WHOIS command directly to client. Client provides
598 the requested attributes to the server. Updated the protocol
599 specs. Protocol TODO #4. Implementation is not done yet
602 * Renamed function silc_client_command_status_message to
603 silc_client_status_message. Affected files are
604 lib/silcclient/command_reply.[ch].

622 options to the server. Affected files silcd/serverconfig.[ch],
623 silcd/command.c and silcd/packet_receive.c.
625 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Added resolve_cmd_ident field to the SilcClientEntry structure
628 too so that if the entry is for example being resolved so
629 another command may attach to the same pending command reply
630 without requiring to resolve the same entry again. Added
631 support for adding multiple pending commands for one
632 command idenfier. Affected files lib/silcclient/command.[ch],
633 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
635 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Defined that server receives WHOIS command reply for private
638 and secret channels too. Updated protocol specs and the
639 code in server. Affected file silcd/command.c.
641 * Defined <channel user mode list> argument to WHOIS command
642 reply for returning user modes on the channels. The
643 channel list now doesn't include the user mode anymore but the
644 actual channel mode. Updated protocol specs and the code in
645 client and server. Affected files are silcd/command_reply.c,
646 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
647 and lib/silcclient/command_reply.c.
649 * Save the channels list in WHOIS command reply in normal server
650 so that WHOIS always shows joined channels also in normal
651 server and not just on router. Affected file is
652 silcd/command_reply.c.
654 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Defined that server receives USERS command reply for private
657 and secret channels too. Updated protocol specs and the
658 code in server. Affected file silcd/command.c.
660 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
662 * Changed the UMODE's mode mask argument to be optional. If
663 not provided then the command merely returns the current mode
664 mask to the client. Updated protocol specs and the server.
665 Affected file is silcd/command.c.
667 * Added SILC session detachment/resuming support. It is possible
668 to detach by closing the network connection and then re-connect
669 and resume to the old client session. Added DETACHED user
670 mode that server will set for detached client. Added new
671 packet RESUME_CLIENT which is used to perform the resuming
672 process. Added DETACH command. Updated the protocol specs,
673 core library, client and server. Protocol TODO #22. Very
674 many affected files around the tree.
676 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Changed the CMODE's mode mask argument to be optional. If
679 not provided then the command merely returns the current mode
680 mask to the client. Updated protocol specs and the server.
681 Affected file is silcd/command.c.
683 * Changed the Killer's Client ID in KILLED notify to be just
684 any ID payload since router server is allowed to kill as well.
685 Updated protocol specs, client libary and server. Affected
686 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
687 and irssi/src/silc/core/client_ops.c.
689 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Added new user modes ANONYMOUS for special anonymous servers
692 that may set the mode for client, and BLOCK_PRIVMSG which
693 client may set to block incoming private messages unless the
694 Private Message Key flag is set (using private keys to protect
695 private messages). Updated protocol specs and code in client
696 and server and core library. Protocol TODO #23. Affected
697 files are lib/silccore/silcmode.h, silcd/server.[ch],
698 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
699 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
701 * Added new channel user mode BLOCK_MESSAGES which the client
702 may set to itself to tell server not send channel messages.
703 Other packets such as channel key packets are still sent.
704 Protocol TODO #23. Updated the protocol specs, client and
705 server. Affected files are lib/silccore/silcmode.h,
706 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
707 lib/silcutil/silcutil.c, silcd/command.c, and
710 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
712 * Redefined the Status Payload to include now two 8 bit fields,
713 instead of one 16 bit field. This now makes it possible to
714 send list of errors. Updated the protocol specs and the code
715 in core library, client library and server. Protocol TODO #1.
716 Affected files are lib/silccore/silccommand.[ch],
717 lib/silcclient/command_reply.[ch], silcd/command.c,
718 silcd/command_reply.c and silcd/packet_receive.[ch].
720 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
722 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
723 must be handled by the application and should tell the application
724 that an error message was already printed, and it should print the
725 config coords (line, filename, ...). Affected files are
726 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
728 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
729 server config parsing code more readable.
731 Fixed a bug in the fetch_logging() config callback.
733 Affected files is silcd/serverconfig.c.
735 * Drop root privileges when started in foreground. Don't drop them
736 if debugging also. Affected file is silcd/silcd.c.

741 for setting various presence information. Added new modes:
742 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
743 specs and code. Protocol TODO #19. Affected files are
744 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
745 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
747 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Added STATS command to the protocol after all, to return
750 various statistical information about the network. It can
751 be used by clients to retrieve statistical information, and
752 servers may use it to to fetch cell and network wide
753 statistics from router. Updated the protocol specs and
754 implemented it to the server. Protocol TODO #16.
755 Affected files are lib/silccore/silccommand, silcd/command.[ch],
756 silcd/command_reply.[ch].
758 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
760 * The LIST command reply in client libary now adds new channel
761 entry if the returned channel doesn't exist yet in cache,
762 and returns the channel entry to the application in the
763 command_reply client operation. Affected file is
764 lib/silcclient/command_reply.c.
766 * Changed the channel message payload's MAC generation to
767 include the IV in the MAC as well. This way all relevant
768 parts of the channel message payload are authenticated also
769 with the channel message MAC (and not only by packet MAC).
770 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
771 Affected file is lib/silccore/silcchannel.c.
773 * Fixed the SKE to save the remote version, since the
774 silc_ske_parse_version mistakenly checked wrong version,
775 after it replaced the start payload. Affected files are
776 lib/silcske/silcske.[ch].
778 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
781 string utility functions. Added there also new functions
782 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
783 Affected files lib/silcutil/silcstrutil.[ch].
785 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
786 files are lib/silcutil/silcstrutil.[ch].
788 * Defined that the security property fields in SKE SHOULD be
789 UTF-8 encoded, defined that version string MUST be US-ASCII
790 encoded, defined that passphrases sent in connection
791 authentication protocol MUST be UTF-8 encoded. Implemented
792 these to the client and server. Defined also that other
793 passphrases sent in the protocol MUST be UTF-8 encoded.
794 Affected files are lib/silcske/silcske.c,
795 lib/silcclient/protocol.c, silcd/protocol.c,
796 silcd/serverconfig.c, and lib/silccore/silcauth.c.
798 * Changed the silc_client_close_connection interface to not
799 need the SilcSocketConnection which should not be visible
800 to application. Affected files are lib/silcclient/client.c
801 and lib/silcclient/silcclient.h.
803 * Rewrote the text for Private Message Key Payload in the
804 protocol specification. Protocol TODO #11.
806 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Upgraded the protocol version to 1.1, updated protocol specs
811 * Added the nickname as new argument to NICK_CHANGE notify and
812 added it to protocol specs and implemented it to client and
813 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
814 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
815 lib/silcclient/client_notify.c.
817 * Added the killer's client ID to the KILLED notify and added
818 it to protocol specs and implemented it to client and server.
819 Protocol TODO #13. Affected files are silcd/command.c,
820 silcd/packet_receive.c, packet_send.[ch],
821 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
822 The killer's client entry is now returned to application in
823 the `notify' client operation.
825 * Fixed the Max Argument fields that had too large value set
826 in the protocol specs. Protocol TODO #14.
828 * Added the LEAVE command reply to return the ID of parted
829 channel. Updated protocol specs and implemented it to the
830 client and server. Protocol TODO #15. Affected files are
831 silcd/command.c, lib/silcclient/command_reply.c. The channel
832 entry is now returned to application in the `command_reply'
835 * Rewrote the version SKE version checking in client libary
836 and in server to use the silc_parse_version_string. Affected
837 files are lib/silcclient/protocol.c, silcd/protocol.c.
839 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
840 commands that was missing it, and updated protocol specs and
841 the server implementation. Protocol TODO #10. The affected
842 file is silcd/command.c.
844 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
845 generic reply to a generic request (REQUEST flag), and
846 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
847 way. A draft-riikonen-silc-flags-payloads-00.txt is written
848 to define the payload for DATA flag. Added the flags to
849 the implementation. Protocol TODO #9. Affected file is
850 lib/silccore/silcchannel.h.
852 Changed the client library to return the message length
853 to application as well in the channel_message and private_message
854 client operations. Affected files are
855 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
856 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
857 and lib/silcclient/client_ops_example.c.
859 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
860 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
861 the channel. Updated protocol specs and impelemented this
862 to client and server. Protocol TODO #6. Affected files are
863 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
864 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
866 Added new options m and M to CMODE command in Irssi SILC
867 client to set these modes.
869 * Deprecated all administrative commands from SILC protocol
870 since they are highly implementation specific commands.
871 Updated protocol specs. Moved the old commands in
872 implementations to private range of command types. Affected
873 files are silcd/command.c, lib/silcclient/command.c and
874 lib/silcclient/command_reply.c. Protocol TODO #8.
876 * Fixed a bug in server where sending unknown command crashes
877 the server. Affected file silcd/command.c.
879 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Added SILC_PROTOCOLVERSION macro to check protocol version
882 of a socket connection. The affected file is
883 lib/silcutil/silcsockconn.h.
885 * Added better error logging in rekey protocol. Affected file
888 * Do not check public key types in SKE during rekey. Affected
889 file lib/silcske/payload.c.
891 * Fixed the rekey protocol with PFS, which was totally broken.
892 Affected file silcd/protocol.c.
894 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
896 * Some client implementations quit network by doing first LEAVE
897 and then immediately SIGNOFF (like Bombyx). We now do check
898 after a short time after LEAVE notify and check whether the
899 client is still valid after LEAVE, and if not we remove it from
900 cache. Affected file is lib/silcclient/client_notify.c.
902 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
904 * Merged version 1.1.4 of zlib. Even if it not currently in use,
905 it's good not to have security holes here.
907 * Fixed a negative refcount situtuation for the config context.
908 Affected file is silcd/serverconfig.c.
910 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
912 * ROBOdoc documented lib/silcutil/silcutil.h.
914 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
916 * Optimized even more the SilcPacketContext structure. Now
917 totally saved 16 bytes of memory per context after optimization.
918 Affected files are lib/silccore/silcpacket.[ch].
920 * Made strict checks for valid SILC IDs. Affected file is
921 lib/silccore/silcid.c.
923 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
925 * Changed the object argument for silc_cipher_register,
926 silc_hash_register, silc_hmac_register and silc_pkcs_register
927 to const. Affected files are lib/silccrypt/silccipher.[ch],
928 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
930 * Changed the silc_get_username and silc_get_real_name to
931 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
933 * Fixed the Irssi SILC Client to use the silc_get_username and
934 silc_get_real_name insted of glib routines since the glib
935 routines only corrupt stack. Fixes the Irssi SILC to work in
936 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
938 * Fixed the Irssi to not use g_get_home_dir since it crashes
939 or returns garbage on cygwin and corrupts stack. Added function
940 get_home_dir to Irssi routines. Affected files are
941 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
943 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Made some structure optimizations. SFTP memory FS MemFSEntry
946 entry structure. Optimized SilcTask structure. Optimized
947 SilcPacketContext structure.
949 Affected files lib/silcsftp/sftp_fs_memory.c,
950 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
952 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
954 * And yet again reverted back the config thing since Johnny
955 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
958 * Fixed memory leaks from config object. Affected files are
959 silcd/serverconfig.[ch].
961 * Added support for adding new connections to the server in rehash.
962 After rehash they take effect.
964 Added support for changing the maximum allowed connections in
965 rehash. The number can grow but going smaller is not supported.
967 Added function silc_server_num_sockets_by_remote to the
968 silcd/server_util.[ch].
970 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
972 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
974 * Added preliminary checking during config parsing for a valid
975 public/private key and removed further checks in the code.
976 Affected files are silcd/serverconfig.[ch], server.c.
978 * Moved functions silc_server_drop() and silc_server_daemonise()
979 from server.c to silcd.c since they are stricly related to
980 the application activity.
982 * Reverted a small part of the automatic ref/unref since
983 it caused a double unref in some situations. Affected
984 files are silcd/silcd.[ch], server.c, serverconfig.c.
986 * Added some .cvsignore files in the lib directory.
988 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Fixed silc_net_gethostbyaddr to correctly resolve by
991 address. Affected file lib/silcutil/silcnet.c.
993 * Fixed the notify relaying to client. The HMAC to be used
994 with relayed packets ws wrong and caused decryption failure
995 at the client end. Affected file is silcd/packet_receive.c.
997 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
999 * Created new branch silc_protocol_1_0_branch.
1001 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1003 * Changed the silc_server_config_* routines to be SilcServer
1004 independent. They are now officially application specific code
1005 and not part of generic server implementation. Affected files
1006 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1008 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1010 * Added automatic referencing of config context in the
1011 silc_server_config_alloc, and automatic unreferencing in the
1012 silc_server_config_destroy. Affected files are
1013 silcd/serverconfig.[ch], silcd/silcd.c.
1015 * Fixed the silc_log_quick handling in the logging routines.
1016 It didn't log quickly when it was TRUE. Affected file is
1017 lib/silcutil/silclog.c. Also the flush delay was set even
1018 if it was 0 in config file. Affected file is
1019 silcd/serverconfig.c.
1021 * Added support for changing key pair of the server in rehash.
1022 Affected file silcd/server.c.
1024 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1026 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1027 too early, before getting the channel entry. Affected file
1028 is silcd/packet_receive.c.
1030 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1032 * Added functions silc_server_config_[ref/unref], these are used
1033 to prevent that the config object is destroyed.
1035 No longer directly affect global variables silc_log_quick and
1036 silc_log_delay, they are first cached inside the config object
1037 and then applied with silc_server_config_setlogfiles().
1039 silc_server_config_set_defaults() is now internal to
1040 serverconfig.c, there are no reasons to show this internal stuff
1043 Affected files are silcd/serverconfig.[ch].
1045 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1046 fprintf's to stderr, since some code may be executed again after
1047 the server went into the background. Affected files are
1050 * Added rehash support. Added function silc_server_rehash() that
1051 will perform all the basic tasks of the rehashing procedure.
1053 * Added command line option `-x, --hexdump'. This will enable the
1054 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1055 The option `--hexdump' implies `--debug'.
1057 * Fixed a bad bug in the logging APIs (silcutil library) where
1058 the application would crash after calling silc_log_reset_all().
1060 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1062 * Fixed the KICKED notify handling in client library to
1063 correctly remove the channel and all entries from the
1064 channel when I was kicked. This bug crashed the client.
1066 Fixed yet another but in KICKED notify handling to remove
1067 the kicked client correctly from the channel.
1069 Affected file is lib/silcclient/client_notify.c.
1071 * Fixed a minor bug in looking up correct client entry
1072 in KICKED notify in server. Affected file is
1073 silcd/packet_receive.c.
1075 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1076 sources correctly to distribution. Fixes --with-gmp option.
1078 * Removed the manual rehashing from ID Cache, and changed it
1079 to use the SILC Hash Table's auto rehash feature. Affected
1080 file is lib/silccore/silcidcache.c.
1082 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1084 * Fixed a bug in the silc_client_nickname_format function that
1085 handles the multiple same nickname formatting. Two clients
1086 with same nickname caused problems after the first one left
1087 and rejoined. It didn't format the nickname correctly.
1088 Affected file is lib/silcclient/idlist.c.
1090 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1092 * Don't change the topic if olod topic is same as new one.
1093 Affected file is silcd/packet_receive.c.
1095 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1097 * Added cross-reference support to the SILC Documentation
1098 generator. All types across all HTML files are now cross-
1099 referenced. Affected files util/robodoc/generator.c and
1100 scripts/silcdoc/silcdoc.
1102 * Added file lib/silcutil/silctypes.h to include all the
1103 arithmetic type definitions and some macros. Removed
1104 includes/bitmove.h and moved macros to silctypes.h.
1106 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1108 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1110 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Added `type' argument to silc_id_payload_parse_id function which
1113 now returns the type of the ID to the sent pointer. Affected
1114 file is lib/silccore/silcid.[ch].
1116 * Added check for CMODE_CHANGE notify type that mode change is
1117 allowed by the sender. Affected file silcd/packet_receive.c.
1119 * Added check for CUMODE_CHANGE notify type that mode change is
1120 allowed by the sender. Affected file silcd/packet_receive.c.
1121 Added the ID type as CUMODE_CHANGE notify type as argument
1122 to the `notify' client operation. Affected files are
1123 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1125 * Added function silc_client_add_server to the client library.
1126 Added support for resolving also channel and server info when
1127 received unknown entity in notify packet. Affected files are
1128 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1130 * Added function silc_command_get_status to return the command
1131 status from the command reply's argument payload. Affected files
1132 are lib/silccore/silccommand.[ch].
1134 * Added check for KICKED notify type that the kicking is
1135 allowed by the client. Affected file silcd/packet_receive.c.
1137 * Created function silc_get_input which can be used to get input
1138 (echo on or off) from user on command line. Affected files are
1139 lib/silcutil/silcutil.[ch].
1141 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1143 * Optimized silc_server_packet_relay_to_channel function.
1144 Added new function silc_channel_message_payload_encrypt which
1145 can be called directly if channel message payload needs to
1146 be encrypted and is already encoded (no need to call _encode
1147 function). Packet relaying is now done by router without any
1148 extra memory allocations. Affected files are
1149 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1150 silcd/packet_send.c.
1152 * Fixed the INVITE notify handling. It took wrong arguments
1153 as invite list and invite delete. Affected file is
1154 silcd/packet_receive.c.
1156 * Added check for TOPIC_SET notify type that the topic change is
1157 allowed by the client. Affected file silcd/packet_receive.c.
1159 * Added check for INVITE notify type that inviting is allowed by
1160 the client. Affected file silcd/packet_receive.c.
1162 * Changed the silc_server_client_on_channel to return the
1163 SilcChannelClientEntry as well. Moved the function
1164 silc_server_check_cmode_rights to server_util.[ch].
1165 Affected files are silcd/server_util.[ch], silcd/command.c.
1167 * Added function silc_server_check_umode_rights to check whether
1168 changing client's user mode is allowed. Added check for
1169 UMODE_CHANGE notify type that the umode change is allowed
1170 by the client. Affected files are silcd/server_util.[ch],
1171 silcd/packet_receive.c and silcd/command.c.
1173 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1175 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1176 ID length. It ignored that ID can be IPv6 based as well.
1177 Affected file lib/silccore/silcpacket.h.
1179 * Fixed the silc_id_id2str and silc_id_str2id to take the
1180 IPv6 address offset's into consideration. Affecte file is
1181 lib/silccore/silcid.c.
1183 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed the internal Unix scheduler functions to check for
1186 NULL context they may receive. The affected file is
1187 lib/silcutil/unix/silcunixschedule.c.
1189 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1191 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1192 can specify different directory with --home command line
1193 parameter. Affected files irssi/src/silc/core/client_ops.c,
1196 * SILC-specific commands aren't now executed if the active server
1197 isn't of SILC-type, so there won't be problems with having
1198 IRC and SILC protocol support in same client. Affected files
1199 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1202 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1204 * Improved the signal support in SILC Schedule. Added new
1205 function silc_schedule_signal_call which is used by application
1206 to mark a signal to be called. It is now safe to perform
1207 any kind of tasks in signal callbacks since it is guaranteed
1208 that the application specified signal callback is called
1209 after the signal is over. Affected files are
1210 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1212 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Added `name' field to SilcChannelPrivateKey to represent
1215 application given name for the key. Moved also the context from
1216 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1217 Added the `name' argument also to the function
1218 silc_client_add_channel_private_key.
1220 Added function silc_client_current_channel_private_key to set the
1221 current channel private key in use.
1223 Added "change" command to KEY command which can be used to change
1224 the current channel private key. Bound the command also to
1225 alt+K (Alt+Shift+k).
1227 Also affected files lib/silcclient/client_channel.c,
1228 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1230 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Added silc_rng_get_byte_fast function in to the
1233 lib/silccrypt/silcrng.[ch].
1235 * Changed the interface of silc_packet_assemble and the
1236 silc_packet_send_prepare. If silc_packet_assmble is now
1237 called the application does not call silc_packet_send_prepare
1238 because the library will call it automatically. These
1239 interfaces now also return a reference to the outgoing buffer
1240 which includes the assembled packet, which the application can
1241 use to encrypt the packet.
1243 Affected files are lib/silccore/silcpacket.[ch],
1244 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1245 silcd/packet_send.c, server_backup.c and packet_receive.c.
1247 * Fixed a packet sending bug on very high load, where outgoing
1248 packet queue wasn't handled correctly and packets got corrupted.
1249 Affected files are lib/silcutil/*/silc*sockconn.c,
1250 lib/silcclient/client.c and silcd/server.c.
1252 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Added macro SILC_PACKET_DATALEN which can be used during
1255 packet assembling to check whether the data to be added to
1256 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1257 len is truncated until it fits it.
1259 Added checks for maximum length of channel message payload and
1260 private message payload also.
1262 Added checks for maximum packet length in server and in
1265 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1266 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1267 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1268 lib/silcclient/client_prvmsg.c.
1270 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Added silc_server_packet_queue_purge call to the
1273 silc_server_disconnect_remote to assure that all data in the
1274 queue before disconnecting is sent to the network. Affected
1275 file silcd/server.c.
1277 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * Added the deleting of server's own ID cache entry to the
1280 silc_server_free function. Free also everything else that
1281 has been allocated in silc_server_init. The affected file
1284 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1286 * Added functions silc_parse_version_string, silc_version_to_num,
1287 and silc_ske_parse_version to parse SILC protocol style version
1288 strings. Affected files lib/silcutil/silcutil.[ch] and
1289 lib/silcske/silcske.[ch].
1291 * Added new configuration params: version_protocol, version_software
1292 and version_software_vendor to specify what version the remote
1293 host must at least be to be able to connect to server. The vendor
1294 string can be regex matched too. Added new function
1295 silc_server_connection_allowed to check maximum number of allowed
1296 connections, and allowed versions for incoming connections.
1297 Affected files are silcd/server.c, server_util.[ch] and
1300 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1302 * Added preliminary support for signals in scheduler. The
1303 signals we care about are now blocked always when the scheduler
1304 is locked. This way we can synchronise the use of signal with
1305 scheduler. It is guaranteed that when signal occurs the scheduler
1306 is not locked, and thus new tasks can be safely added to the
1309 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1310 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1311 Added new platform specific routines
1312 silc_schedule_internal_signals_[un]block and
1313 silc_schedule_internal_signal_[un]register.
1315 Added new functions to SILC Schedule API:
1316 silc_schedule_signal_[un]register. Each signal that application
1317 is going to use should be registered to the scheduler.
1319 Affected files are lib/silcutil/silcschedule.[ch],
1320 lib/silcutil/*/silc*schedule.c.
1322 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1324 * Check for unauthenticated client and server in the
1325 silc_server_new_client and silc_server_new_server functions.
1326 Affected file silcd/packet_receive.c.
1328 * Added function silc_string_is_ascii to check whether given
1329 string is 7-bit ASCII string. Affected files are
1330 lib/silcutil/silcutil.[ch].
1332 * Added function silc_id_is_valid_server_id into the
1333 silcd/serverid.c and added checking for valid Server ID's in
1334 silc_server_new_server. The Server ID must always be based
1335 on the server's public IP address.
1337 * Added logging of DISCONNECT packet message in the server.
1338 Affected file silcd/server.c.
1340 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Changed all library interfaces that use Global RNG to also
1343 accept SilcRng as argument. Affected files are
1344 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1345 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1346 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1347 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1348 lib/silccrypt/rsa.c.
1350 * Added function silc_pkcs_generate_key to the
1351 lib/silccrypt/silcpkcs.[ch] for applications so that they
1352 don't need to do pkcs->pkcs->init calls anymore.
1354 * Remove SilcSocketConnection from the SFTP API since it really
1355 wasn't needed there. The application has the information
1356 saved in its contexts anyway and the SFTP layer doesn't need
1357 know about it. Affected files lib/silcsft/silcsftp.h and
1358 lib/silcsftp/sftp_[server/client].c.
1360 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1361 The SilcSimContext is not SilcSim.
1363 * Fixed possible buffer overflows in silc_id_render in the
1364 lib/silcutil/silcutil.c.
1366 * On EPOC the global crypto module lists are not used at all
1367 in the crypto library. Added support for using the constant
1368 algorithm list on EPOC. Affected files are
1369 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1372 * Fixed the handling of third parameter of KICKED notify, since
1373 it was mistakenly updated to SILC Protocol 1.0 even though it
1374 is to be included in 1.1. Since it is not in 1.0 it is not
1375 mandatory, and this fix now handles it only if it is provided,
1376 and it is not error if it is not provided. Affected file
1377 lib/silcclient/client_notify.c.
1379 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1381 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1382 client. Affected file irssi/src/silc/core/client_ops.c.
1384 * Merged with Irssi 0.8.4 from irssi.org CVS.
1386 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1388 * Check for valid socket connection in client entries before
1389 sending any messages. Fixes a crash, but doesn't fix some
1390 other underlaying bug that is lurking there. Affected
1391 file silcd/packet_send.c.
1393 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1395 * $usermode, $cumode and $cumode_space expandos shouldn't do
1396 anything with non-SILC server records. Affected file
1397 irssi/src/silc/core/silc-expandos.c
1399 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed the silc_net_check_[host/local]_by_sock to support
1402 IPv6 bound sockets as well. Now they can return IPv6 addresses
1403 as well. Affected file lib/silcutil/silcnet.c.
1405 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1406 Affected lib/silcutil/unix/silcunixnet.c.
1408 * Fixed ID rendering (at least on some platforms, not NetBSD)
1409 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1411 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * Added silc_hash_public_key and silc_hash_public_key_compare
1414 functions to be used with SilcHashTable. They can be used to
1415 hash public keys and compare public keys in hash table. Affected
1416 file lib/silcutil/silcutil.[ch].
1418 * Added support for specifying multiple public keys for Client
1419 connection section in server configuration file. This makes it
1420 possible to accept multiple public keys from same host, or to
1421 make a section that accepts any incoming host, and have the
1422 accepted public keys listed in the section.
1424 Added functions silc_sever_[find/get]_public_key, added the
1425 support for this actually to all connection sections but only
1426 the Client section is currently allowed to specify multiple
1429 Affected files are silcd/server.c, server_internal.h,
1430 command.c, protocol.c, server_util.[ch], packet_receive.c.
1432 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Merged Irssi 0.8.2 from irssi.org CVS.
1436 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1438 * If silc_debug is TRUE, also output standard logging messages
1439 to stderr with the debug output.
1441 Made silc_log_reset_all() flushing all channels before returning.
1442 Also fixed some documentation typos.
1444 Affected files are lib/silcutil/silclog.[ch].
1446 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1448 * Fixed the server to check correctly the amount of connections
1449 from single host, by checking also the type of the connection.
1450 Fixed also the comparison of number of connections and number
1451 of allowed connections. Affected files are silcd/server.c,
1454 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1456 * Fixed the USERS command reply to save the user's mode on the
1457 channel as well. Fixed JOIN command reply to check whether a
1458 client is on channel already and not join it twice. Affected
1459 file lib/silcclient/command_reply.c.
1461 * Added new file silc-expandos.c into irssi/silc/core/ to return
1462 various stuff for various signal for the statusbar etc. updating.
1463 Now Irssi SILC client prints channel user modes etc. on the
1466 * The user mode (like server/router operator changes) is now shown
1467 on the Irssi SILC client's statusbar. The affected files are
1468 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1470 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1472 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1473 to SILC_SCHEDULE_[UN]LOCK macros.
1475 * Added more error printing to logs in server code. Affected
1476 files silcd/server.c and silcd/protocol.c.
1478 * Fixed -S option parsing in Irssi SILC Client. Affected file
1479 irssi/src/silc/core/silc-core.c.
1481 * Added silc_buffer_alloc_size function. Affected file is
1482 lib/silcutil/silcbuffer.h.
1484 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1486 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1487 constants. Affected files in
1488 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1491 * Changed the internal SFTP Memory FS table to const. Affected
1492 file lib/silcsftp/sftp_fs_memory.c.
1494 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed the buffer formatting and unformatting routines to
1497 check the size of 64 bits types with sizeof(). Affected
1498 file is lib/silcutil/silcbuffmt.c.
1500 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1502 * Removed 0.6.x backwards support.
1504 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1506 * Changed all integer type names:
1507 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1508 to avoid collisions with other libraries using same type names
1511 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1513 * Added `prefer_ipv6' argument to the functions
1514 silc_net_gethostbyname[_async]. If it is TRUE it will return
1515 IPv6 address over IPv4. If FALSE IPv4 address is returned
1516 even if IPv6 address was found. Affected files
1517 lib/silcutil/silcnet.[ch].
1519 * Added support silc_net_create_connection[_async] to fallback
1520 to IPv4 address if IPv6 address could not be used (like if
1521 it doesn't work on a specific system). Affected file in
1522 lib/silcutil/unix/silcunixnet.c.
1524 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1526 * Added silc_schedule_reinit function to do the enlarging
1527 of the max tasks handling capabilities of the scheduler.
1528 Affected files lib/silcutil/silcschedule.[ch].
1530 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1532 * Added automatic extern "C" { ... } for C++ compilers so the
1533 application does not need to define them. Affected file
1534 includes/silcincludes.h.
1536 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1537 old name went against naming convention. Applications now
1538 include "silcclient.h" instead of "clientlibincludes.h".
1539 Removed includes/clientlibincludes.h, it is redundant now.
1541 * Renamed includes/version.h to silcversion.h.
1543 * Added really preliminary support for OS/2 into the util
1544 library. Only thread & mutex API is implemented, others
1545 are still to be implemented. Created the lib/silcutil/os2/

1579 * Added `user_count' to the SilcChannelEntry which now tells the
1580 number of users on the channel. The user count is now saved
1581 in normal server of global channels as well. Affected files
1582 silcd/server.c, idlist.h, packet_receive.c and command.c.
1584 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1585 include file utility functions.

1601 the SKE interface a bit.
1603 * Fixed padding problem in PKCS#1. The padding was not actually
1604 random since the random number generator was used incorrectly.
1605 This security bug affects only when encrypting with PKCS#1, and
1606 it is not currently used at all in SILC. SILC only use signing
1607 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1670 Affected files irssi/src/silc/core/silc-core.c,
1671 irssi/src/fe-text/silc.c.
1673 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1675 * Added new configuration options and blocks:
1676 keepalive_secs, reconnect_count, reconnect_interval,
1677 reconnect_interval_max, reconnect_keep_trying and
1678 require_reverser_lookup. Added ConnectionParam block, and
1679 implemented the connection parameters when connecting as
1680 initiator and when accepting connections as responder.

1692 the connection configuration object from the SilcServerConnection
1693 object instead of finding it during the connecting phase.
1694 Added the configuration object to SilcServerConnection struct.
1695 Affected files silcd/server_internal.h, server.c.
1697 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Add the client on channel after it was resolved at the
1700 channel message receiving, and it was not already on the
1701 channel. Affected file lib/silcclient/client_channel.c.
1703 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1719 authentication to be set at the same time.
1721 Added `prefer_passphrase_auth' setting in config file which
1722 can be used to set to prefer passwd auth if both passwd and
1723 public key is set. If not set, public key is preferred.
1724 This has effect only when being initiator (responder will try
1727 Added support for authentication with passphrase and public key
1728 at the same time. The passphrase is tried first always since
1729 it is faster to check.
1731 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1733 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1735 * Merged the new SILC Config library, with the server parsing

1779 * Fixed the file transfer's key agreement payload to include
1780 zero port also if the hostname is NULL because it could not
1783 Call file transfer monitor callback now also if error occurs
1784 during key agreement protocol.
1786 Changed the silc_client_file_send interface to return the
1787 SilcClientFileError instead of session id. The session ID
1788 is returned into pointer provided as argument.
1790 Check that the file exists locally before sending the
1791 file transfer request at all.
1793 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1795 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1796 error than can occur while key agreement protocol. Affected
1797 file lib/silcclient/silcapi.h.

1805 file lib/silcutil/silclog.c.
1807 * Fixed the channel message payload decryption in the function
1808 silc_channel_message_payload_decrypt to not modify the original
1809 buffer before it is verified that the message decrypted
1810 correctly. Otherwise, next time it is called with correct
1811 channel key it won't encrypt since the payload is corrupted.
1812 Affected file lib/silccore/silcchannel.c.
1814 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1826 * Fixed a bug in hash table internal routine for traversing
1827 the table with foreach callback. The current entry may
1828 become invalid in the callback but it was referenced after
1829 the callback returned.
1831 Do not allow auto rehashing of hash table during the
1832 silc_hash_table_foreach operation, for same reasons as it is
1833 not allowed for SilcHashTableList. Affected files are
1834 lib/silcutil/silchashtable.[ch].
1836 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1842 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1844 * Fixed private message handling. It used some old code that
1845 caused the client to crash. Affecte file is
1846 lib/silcclient/client_prvmsg.c.
1848 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1850 * Added function silc_client_add_channel,
1851 silc_client_replace_channel_id, and removed functions
1852 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1853 from client library.
1855 * Added cross reference of the joined channels to the
1856 SilcClientEntry, and changed the SilcChannelEntry's
1857 users list to SilcHashTable. The affected files are
1858 lib/silcclient/idlist.[ch].
1860 * Fixed a bug in hash table tarversing. While the hash table
1861 is traversed with SilcHashTableList the table must not be
1862 rehashed. It is now guaranteed that auto rehashable tables
1863 are not rehashed while tarversing the list. Also defined that
1864 silc_hash_table_rehash must not be called while tarversing
1865 the table. Added function silc_hash_table_list_reset that must
1866 be called after the tarversing is over. The affected files are
1867 lib/silcutil/silchashtable.[ch].
1869 * Changed all hash table traversing to call the new
1870 silc_hash_table_list_reset in server and in client library.
1872 * Added function silc_client_on_channel to return the
1873 SilcChannelUser entry if the specified client entry is joined
1874 on the specified channel. This is exported to application as
1875 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1877 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1879 * Fixed founder regaining problem with JOIN command on normal
1880 server. The notify for mode change must be sent always and
1881 not only if !cmd->pending. Affected file silcd/command.c.
1883 * Fixed the WHOWAS command's reply sending to support the
1884 lists correctly. Affected file silcd/command.c.
1886 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1888 * When sending JOIN command to router for processing the
1889 sender's old command identifier was not saved back to the
1890 sender's command context, fixed now. The affected file is
1893 * Create the key in JOIN command of the router did not return
1894 the channel key, added check for this. Affected file is
1897 * Fixed a channel ID update bug in JOIN command reply. Do
1898 not directly upgrade the ID but call the function
1899 silc_idlist_replace_channel_id if the ID was changed.
1900 Affected file silcd/command_reply.c.
1902 * Fixed memory leaks from command calling if it would fail.
1903 Affected file silcd/command.c.
1905 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1915 * Removed TRQ from lib/trq, not needed anymore.
1917 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1918 with server connections. Later this will be configurable
1919 in config file after new config file is done. Affected file
1922 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1924 * Fixed a crash in server related to channel announcements.
1925 Affected file silcd/server.c.
1927 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1929 * Fixed memory leaks in silc_server_create_new_channel*
1930 functions. Affected file silcd/server.c.
1932 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1933 which ID was changed. This way the router will send the
1934 user list for the channel again, and server won't be in
1935 desync in some rare circumstances. Affected file is
1936 silcd/packet_receive.c.
1938 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1940 * Check for NULL socket pointer in the function

1953 file for application programmers to quickly start using
1954 the SilcClientOperation functions in their application.
1955 Updated the lib/silcclient/README as well to tell about this
1956 nice file made available.
1958 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1960 * Call silc_server_remove_from_channels when removing client
1961 entry when NO_SUCH_CLIENT_ID was received. Affected file

1966 * Added server & router operator statistics updating. Affected
1967 file silcd/packet_receive.c and silcd/command.c.
1969 * Fixed the SERVER_SIGNOFF notify handling on normal server
1970 not to save the history information for clients. Same was
1971 fixed earlier in remove_clients_by_server function, but not
1972 here. Affected file silcd/packet_receive.c.
1974 * Raised the default connection-retry count from 4 to 7 in
1975 server. Affected file silcd/server.h.
1977 * Cancel any possible reconnect timeouts when we start the
1978 key exchange. Affected file silcd/server.c.
1980 * Do not reconnect on connection failure when SCONNECT was
1981 given. Affected files silcd/server.[ch].
1983 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1985 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1987 * Fixed the NICK command to always give the unformatted
1988 nickname to the one giving the NICK command. If unformatted
1989 nickname is cached already it will be formatted and the
1990 local entry will always get the unformatted nickname.
1991 Affected file lib/silcclient/idlist.c.
1993 * Fixed some double frees from client library commands.
1994 Affected file is lib/silcclient/command.c.
1996 * Fixed CUMODE command in server to assure that no one can
1997 change founder's mode than the founder itself, there was a
1998 little bug. Affected file silcd/command.c.
2000 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2002 * Removed the SilcClientCommandDestructor from the client
2003 libary, it is not needed anymore. Affected files are
2004 lib/silcclient/silcapi.h, command[_reply].[ch],
2005 client_notify, idlist.c.
2007 * Fixed GETKEY command to first resolve client, and then
2008 resolve the server only if the client was not found, instead
2009 of resolving both at the same time. Affected file is
2010 lib/silcclient/command.c.
2012 * Added silc_client_start_key_exchange_cb and lookup the
2013 remote hostname and IP address before starting the key
2014 exchange with server. The affected file is
2015 lib/silcclient/client.c.
2017 * The server's public key is now saved using the IP address
2018 of the server and not the servername for the filename.
2019 The hostname public key filename is checked as an fall back
2020 method if the IP address based filename is not found.
2022 Fixed the GETKEY command to save the fetched server key
2023 in correct filename.
2025 Print the remote server's hostname now when new key is
2026 received during connection process. Affected file is
2027 irssi/src/silc/core/client_ops.c.
2029 * Return always our own public key to the client if it asks
2030 for it with GETKEY command. Affected file silcd/command.c.
2032 * Removed the use_auto_addr variable from default config
2033 file since it was in wrong section. Affected file is
2036 * Fixed TOPIC_CHANGE notification to not route it when it
2037 was sent using silc_server_send_notify_to_channel function.
2038 Affected file silcd/command.c.
2040 * Fixed silc_server_send_notify_kicked to send the kicker's
2041 Client ID also, it was missing. Affected files are
2042 silcd/command.c, silcd/packet_send.[ch].
2044 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2046 * Do not save client history information in SERVER_SIGNOFF.
2047 Fixes the bug in normal server that it does not detect
2048 the client becoming valid after the server becomes back
2049 online. Affected file silcd/server_util.c.
2051 * Added `sock_error' field into the SilcSocketConnection
2052 context. When error occurs during socket operation (read
2053 or write) the error is saved. Added also new function
2054 silc_socket_get_error to return human readable socket error
2055 message. Affected files are lib/silcutil/silcsockconn.[ch],
2056 lib/silcutil/unix/silcunixsockconn.c, and
2057 lib/silcutil/win32/silcwin32sockconn.c.
2059 * The server now prints the socket error message in the
2060 signoff for client. Affected file silcd/server.c.
2062 * Fixed the `created' channel information sending from router
2063 to server in JOIN command. Checks now whether the channel
2064 really was created or not and set it according that.
2066 Fixed the JOIN command to use the client entry's current
2067 ID during the joining procedure instead of the one it sent
2068 in the command (it is checked though), since it can change
2069 between the packet processing and command processing, and
2070 would just case unnecessary pain in the client end. Affected
2071 file silcd/command.c.
2073 * Fixed a channel key payload sending to use correct channel
2074 ID when the server was forced to change the channel's ID by
2075 router. Router sent the key payload with the old Channel ID.
2076 Affected file silcd/packet_receive.c.
2078 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2080 * Call silc_server_save_channel_key only if the key payload
2081 was provided in the JOIN command's command reply. Affected
2082 file silcd/command_reply.c.
2084 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2086 * Fixed silc_mp_sizeinbase to return the value correctly with
2087 MPI. Affected file lib/silcmath/mp_mpi.c.
2089 * Fixed the stop_server signal to correctly stop the scheduler
2090 and gracefully stop the server when SIGTERM or SIGINT signals
2091 are received. Affected file silcd/silcd.c.
2093 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2095 * Simple handling of TERM and HUP signals. Also added some log
2096 flushing call around. Affected file is
2099 * Fixed small bugs in silclog.c. Now buffering output will take
2100 effect after 10 seconds since startup: This will ensure that
2101 no important startup messages are lost. Also output redirection
2102 will preserve original format ([Date] [Type] message).
2103 Affected file is lib/silcutil/silclog.c.
2105 * Added two options to the config file, in the logging section:
2106 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2107 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2109 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2111 * Do not print the warning about log files not being initialized
2112 more than once to avoid excess logging. Affected file is
2113 lib/silcutil/silclog.c.
2115 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2116 the SIM copying in make install in Makefile.am.pre.
2118 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2120 * Rewritten silclog APIs. Globally interesting changes follows:
2121 silc_log_set_files() changed to silc_log_set_file().
2122 silc_log_set_callbacks() changed to silc_log_set_callback().
2123 ROBOdoc documented silclog header file.
2124 SilcLogCb now returns bool to wether inihibit the default
2125 handler or not (to keep the old behaviour return always TRUE).
2126 The new APIs should also fix the problem of the
2127 silcd_error.log file that was written in the current directory.
2130 Log files streams will remain opened after silc_log_set_file()
2131 call, means less CPU usage notably on high traffic servers.
2132 File streams are now full buffered, and flushed to the disk
2133 every 5 minutes, lesses HD activity and CPU usage.
2134 Messages can be redirected, allowing admins to configure
2135 one single logfile for all server messages.
2136 the silc_log_quick global variable to activate fast-logging.
2137 Affected files lib/silcutil/silclog.[ch]
2139 * Changed some code to conform new silclog APIs. Affected
2140 files are doc/example_silcd.conf.in, silcd/server.c
2141 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2144 * Fixed a memory leak that could occur in some situations.
2145 Affected file silcd/serverconfig.c.
2147 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2149 * Added the silc_client_del_client to remove the client from
2150 all channels as well. Affected file lib/silcclient/idlist.c.
2152 * Fixed the client library to correctly remove the client
2153 from all channels when the client entry is being destroyed.
2154 Affected file lib/silcclient/client_notify.c, command.c.
2156 * Added auto-nicking support to the client library. If the
2157 applicatio now sets client->nickname it will be sent to the
2158 server after connecting by the library. This way for example
2159 SILCNICK (or IRCNICK) environment variables will have effect
2160 and always change the nickname automatically to whatever
2161 it is wanted. Affected file lib/silcclient/client.[ch].
2163 * Renamed silc_server_command_bad_chars to the
2164 silc_server_name_bad_chars and moved it to the
2165 silcd/server_util.[ch]. Added also new function
2166 silc_server_name_modify_bad to return nickname that
2167 includes bad characters as new nickname without those
2168 bad characters. This check and modify is now used in
2169 silc_server_new_client when the username is initially set
2170 as nickname, so it must be checked to be valid nickname.
2171 Affected file silcd/packet_receive.c.
2173 * The nickname length is now taken from the packet for real
2174 and not trusted to strlen() since it clearly can return
2175 wrong length for nickname including bad characters. This
2176 also applies to channel names. Affected file silcd/command.c.
2178 * Removed the lib/silcsilm/modules directory. Modules are now
2179 compiled into the lib/silcsim. Fixed the copying of the
2180 modules to follow symbolic links in Makefile.am.pre.
2182 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed silc_string_regexify list creation. Fixes bugs with
2185 BAN and INVITE commands in server. The affected file is
2186 lib/silcutil/unix/silcunixutil.c.
2188 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Removed the command destructor entirely from the server's
2191 command and command reply routines. It is not needed, and
2192 its usage was buggy and caused crashes. Affected files are
2193 silcd/command[_reply].[ch].
2195 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Cancel protocol and NULL sock->protocol if timeout
2198 occurred during protocol. Affected file silcd/server.c.
2200 * Cancel protocol timeouts always before calling the final
2201 callback, to assure that after final callback is called
2202 no other state will be called for the protocol anymore.
2203 Affected file silcd/protocol.c.
2205 * Print error log if incoming connection configuration could
2206 not be found. Affected file silcd/server.c.
2208 * Fixed JOIN command to correctly save the founder mode
2209 to the client on normal SILC server, when the channel
2210 was created by the router. Affected file silcd/command.c.
2212 * Fixed LIST command (hopefully) to send correct reply
2213 packets. Affected file silcd/command.c.
2215 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * The silc_packet_receive_process now returns FALSE if the
2218 read data was invalid packet, and TRUE if it was ok.
2220 The server now checks that if unauthenticated connection
2221 sends data and its processing fails the server will close
2222 the connection since it could be a malicious flooder.
2224 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2226 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Make sure the warning about error opening a log file is
2229 printed only once and not everytime it fails (produces
2230 too much useless log). Affected file lib/silcutil/silclog.c.
2232 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2234 * Made the silc_server_daemonise() function more readable.
2235 Affected file silcd/server.c.
2237 * Pid file is now optional, the user may comment it out from
2238 the config file. Removed define SILC_SERVER_PID_FILE, we
2239 don't need a default any longer. Affected file
2240 configure.in.pre, lib/Makefile.am.pre.
2242 * Make some use of the pid file. The server now dies at startup
2243 if it detects a valid pid file on his path. The server would
2244 die anyway in this circumstance, because of the bind() failure.
2245 Affected file silcd/silcd.c.
2247 * No longer compiling lib/dotconf.
2249 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Fixed JOIN command parsing not to crash. Affected file
2252 lib/silcclient/command.c.
2254 * Fied the NICK_CHANGE notify to add the new client entry
2255 even it is resolved. This removes an <[unknown]> nick
2256 thingy bug in the client. Affected file is
2257 lib/silcclient/client_notify.c.
2259 * Do not try to allocate 0 bytes (efence does not like it)
2260 in lib/silccore/silccomand.c when encoding payload.
2262 * Do not take IRCNICK as nickname in Irssi SILC client since
2263 it is not possible to set nickname before hand connecting
2264 the server (TODO has an entry about adding auto-nicking
2267 * Changed the silc_server_command_pending to check whether
2268 there already exists an pending entry with the specified
2269 command, command identifier and pending callback. This is
2270 to fix IDENTIFY and WHOIS related crashes that may register
2271 multiple pending commands with same identifier. Affected
2272 file silcd/command.c.
2274 * Fixed the server to reconnect to the router even if it
2275 was already reconnecting and EOF was received. This to
2276 fix a possibility that the server wouldn't ever try to
2277 auto-reconnect to the router. Affected file silcd/server.c.
2279 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Fixed the server's password authentication to use the
2282 length of the locally saved password, and not the one
2283 sent in the packet. Affected file silcd/protocol.c.
2285 * Fixed same password authentication problem in the
2286 Authentication Payload handling routines in
2287 lib/silccore/silcauth.c.
2289 * Yet another password authentication problem fixed with
2290 channel password handling in silcd/command.c.
2292 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * If first character of string in silc_parse_userfqdn is '@'
2295 then do not parse it. Affected file is
2296 lib/silcutil/silcutil.c.
2298 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Fixed minor bug in IDENTIFY command reply sending, which
2301 caused various weird problems during JOIN when it was
2302 resolving names for users. Affected file silcd/command.c.
2304 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Fixed the IDENTIFY command reply sending to chech better valid
2307 clients. It was possible to send incomplete list of replies.
2308 Affected file silcd/command.c.
2310 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Added silc_client_command[s]_[un]register functions now to
2313 dynamically register the commands in client library. Removed
2314 the static table of commands. This allows the client library
2315 to call commands without causing the application to know about
2316 what commands library has called.
2318 Removed the INFO command reply kludge to detect when the command
2319 was called by library. Now library use its own command reply
2320 function for INFO command.
2322 Added function silc_client_command_call to call a command.
2323 Application can use it to call command, not access the structure
2326 Now all commands that are sent by the client library (not
2327 explicitly sent by application) use own command reply functions.
2329 Affected files around lib/silcclient/ and in
2330 irssi/src/silc/core/.
2332 * Fixed the WHOIS command reply sending to chech better valid
2333 clients. It was possible to send incomplete list of replies.
2335 Fixed the WHOIS and IDENTIFY to send the request to router
2336 if normal server did not do it and did not find any results.
2338 Affected file silcd/command.c.
2340 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Moved the internal data from SilcClient context into its
2343 own file, not accesible to application. Affected files
2344 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2345 and other files in client library.
2347 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Added doc/examples installation target in Makefile.am.pre.
2352 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2355 commands the found client entry will be removed from the
2356 cache, after notifying application about the error. Affected
2357 file lib/silcclient/command_reply.c.
2359 * Changed the /MSG to check for exact nickname user gave, and
2360 not let `nick' match `nick@host' if it is only one found. Now,
2361 user must type the exact nickname (like nick@host2) even if
2362 there are no more than one same nicks found. This is to avoid
2363 a possibility of sending nickname to wrong nickname since
2364 `nick' could match `nick@host'. Affected file is
2365 irssi/src/core/silc-servers.c.
2367 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Do not print "you are now server operator" or similar when
2370 giving /away command. Affected files are
2371 irssi/src/silc/core/client_ops.c, silc-servers.h.
2373 * Made the silc_server_command_pending_error_check to send
2374 the same command reply payload it received back to the
2375 original sender of the command. This way all arguments
2376 that was received by the server will be received by the
2377 client too. Affected file silcd/command.c.
2379 * Added the silc_idcache_add to return the created cache entry
2380 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2382 * Add global clients to expire if they are not on any channel.
2383 This is because normal server will never know if they signoff
2384 if they are not on any channel. The cache expiry will take
2385 case of these entries. This is done by normal servers only.
2386 The affected files are silcd/command_reply.c,
2387 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2389 * If server receives invalid ID notification for WHOIS or
2390 IDENTIFY and the ID exists in the lists, it is removed.
2391 Affected file silcd/command_reply.c.
2393 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2394 in client then client entry that it matches is searched and
2395 the nickname is printed on the screen for user. Affected
2396 file irssi/src/silc/core/client_ops.c.
2398 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Use cache entry expire time in the LIST command reply to
2401 purge old entries from the cache after the LIST command
2402 reply has been received. This way we don't have non-existent
2403 entries in the cache for too long. Affected file is
2404 silcd/command_reply.c.
2406 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * If we are normal server, and we've not resolved client info
2409 in WHOIS or IDENTIFY from router, and it is global client,
2410 we'll check whether it is on some channel. If it is not
2411 then we cannot be sure about its validity and will resolve it
2412 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2413 file silcd/command.c.
2415 * Search channel by name (if possible) rather than by ID
2416 in IDENTIFY command's command reply. Affected file is
2417 silcd/command_reply.c.
2419 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2422 Updated specs and implemented it. Affected file silcd/command.c,
2423 silcd/packet_send.c and silcd/packet_receive.c.
2425 * Implemented the <founder auth> payload handling in the JOIN
2426 command. If provided all conditions for channel joining
2427 except requirement to provide correct passphrase can be
2428 overrided by the channel founder. Updated the protocol specs.
2429 Affected file silcd/command.c.
2431 Added support for founder auth in JOIN command in client
2432 library. Fixed the parsing of the JOIN command now to support
2433 all options as they should be. The affected file is
2434 lib/silcclient/command.c.
2436 * Optimized the WHOIS and IDENTIFY commands to send the request
2437 to router only if it includes nicknames or other names. If
2438 they include only IDs then check the local cache first before
2439 routing. Affected file is silcd/command.c.
2441 * Added channels topic announcements. Affected file is
2442 silcd/packet_receive.c and silcd/server.c.
2444 * Fixed the silc_server_send_notify_topic_set to really destine
2445 the packet to channel. Affected file silcd/packet_send.c.
2447 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2448 library. Affected file lib/silcclient/client_notify.c.
2450 * Added UMODE announcements. Affected file silcd/server.c.
2452 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Memory leak fixes in:
2456 lib/silcutil/silcsockconn.c
2457 lib/silcske/silcske.c
2458 lib/silcske/groups.c
2460 lib/silccrypt/silcpkcs.c
2461 lib/silccore/silccommand.c
2462 lib/silccore/silcidcache.c
2467 * ROBOdoc documented the lib/silcske/groups.h file and a
2468 bit changed the interface for better.
2470 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2472 * Update the client entry context in the ID cache after
2473 nick change. Affected file lib/silcclient/command.c.
2474 Fixes the CUMODE command when regaining founder privileges,
2475 and a little WHOIS problem.
2477 * Fixed silc_net_gethostbyname to correctly call the
2478 inet_ntop. Affected file lib/silcutil/silcnet.c.
2480 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2482 * Added IPv6 support checking to the configure.in.pre, added
2483 also --enable-ipv6 option to override the check. Affected
2484 file configure.in.pre.
2486 * The silc_thread_create now calls the start function
2487 directly if threads support is not compiled in. Removes
2488 ugly #ifdef's from generic code. Affected files are
2489 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2491 * Added silc_net_gethostby[name/addr]_async to asynchronously
2492 resolve. Affected files are lib/silcutil/silcnet.[ch].
2494 * Added support for rendering IPv6 based server, client and
2495 channel IDs. Affected file lib/silcutil/silcutil.c.
2497 * Added support for creating IPv6 based server IDs. Affected
2498 file is silcd/serverid.c.
2500 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2502 * Added silc_net_gethostby[addr/name] into the
2503 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2504 routines. Added silc_net_is_ip[4/6]. Affected file is
2505 lib/silcutil/unix/silcunixnet.c. All routines that take
2506 address as argument now supports both IPv4 and IPv6 addresses.
2508 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2510 * Fixed LIST command reply sending in server. Affected file
2513 * Server now sends the kicker's client ID in the KICK notify
2514 to the kicked client. Affected file silcd/command.c.
2516 * The client library now parses the kickers client ID and
2517 UI displays it. Affected files lib/silcclient/client_notify.c
2518 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2520 * Made all payload parsing function prototypes consistent.
2521 They all take now const unsigned char * and uint32 pair as
2522 the payload data instead of SilcBuffer. Changes all around
2523 the source tree. Other unsigned char* -> const unsigned char*
2524 changes around the tree as well.
2526 * Optimized SFTP client and server packet sending not to
2527 allocate new buffer for each packet but to recycle the
2528 first allocated buffer. Affected files are
2529 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2531 * Optimized the SFTP client to use SilcList instead of
2532 SilcDList for requests, because it is faster. Affected file
2533 is lib/silcsftp/sftp_client.c.
2535 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2536 into lib/silccore/silcid.[ch].
2538 Renamed silcpayload.[ch] into silcargument.[ch].
2540 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2542 * If client entry is deleted with active key agreement
2543 session, abort the session.
2545 The silc_client_abort_key_agreement now calls the completion
2546 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2548 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2551 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Don't use __restrict in older GCC's. Affected file is
2554 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2556 * silc_net_localhost now attempts to reverse lookup the
2557 IP/hostname. Affected file lib/silcutil/silcnet.c.
2559 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2560 command. It can be used to gain founder privileges at
2561 the same time when joining the channel.
2563 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2564 kicker's client ID as well. Updated protocol specs.
2566 Defined that the server must send SILC_COMMAND_IDENTIFY
2567 command reply with error status to client who sent
2568 private message with invalid client ID.
2570 Updated the protocol specification.
2572 * Added silc_server_send_command_reply to send any
2573 command reply. Affected file silcd/packet_send.[ch].
2575 * Added silc_id_payload_encode_data to encode ID payload
2576 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2578 * The server now send IDENTIFY command reply with error
2579 status if client ID in private message is invalid. Affected
2580 file silcd/packet_receive.c.
2582 * Save the server key file with server's IP address in
2583 the filename instead of hostname. The affected file is
2584 irssi/src/silc/core/client_ops.c.
2586 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2591 * Added libtool support for compiling shared objects in
2592 lib/silcsim. Affected file configure.in.pre and
2593 lib/silcsim/Makefile.am. Original patch by cras.
2595 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Pid file configuration, and server's config file fixes
2598 patch by toma. Updated CREDITS file.
2600 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2602 * Fixed silc_client_channel_message to not try to decrypt
2603 the message twice if it resolved the destination client
2604 information. This could cause of dropping one channel
2605 message. Affected file lib/silcclient/client_channel.c.
2607 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2610 lib/silcclient/client.c. This function is used when the SILC
2611 Client is run under some other scheduler, or event loop or
2612 main loop. On GUI applications, for example this may be
2613 desired to used to run the client under the GUI application's
2614 main loop. Typically the GUI application would register an
2615 idle task that calls this function multiple times in a second
2616 to quickly process the SILC specific data.
2618 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2620 * Fixed silc_server_drop() for dropping the supplementary
2621 groups as well, this could cause a security hole on some
2624 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2629 * Write PID file after dropping privileges. Added -F option
2630 to run server on foreground. A patch by debolaz.
2631 Affected files silcd/server.c, silcd/silcd.c.
2633 * Fixed MOTD to return the MOTD file server name. Affected
2634 file silcd/command.c.
2636 * Added INFO command reply handling to the Irssi SILC Client.
2637 Affected file irssi/src/silc/core/client_ops.c.
2639 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Fixed the silc_idcache_list_* routines to really support
2642 the dynamic list. Fixes a crash. Affected file is
2643 lib/silccore/silcidcache.c.
2645 * Fixed the LIST command reply to really call LIST command's
2646 pending callbacks. Affected file silcd/command_reply.c.
2648 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Update conn->local_entry->nickname after giving NICK
2651 command. Affected file lib/silcclient/command.c.
2653 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2655 * Added the [pid] option to the silcd configuration file
2657 Affected files: serverconfig.[ch] and silcd.c
2659 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Save fingerprint in WHOIS command reply in server.
2662 Affected file silcd/command_reply.c.
2664 * Fixed NICK commands pending callback registration.
2665 Affected file lib/silcclient/command.c.
2667 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Use ++server->cmd_ident when sending commands in server,
2670 instead of random number. Affected file silcd/command.c.
2672 * Fixed GETKEY command reply to call actually GETKEY pending
2673 command callbacks. Affected file silcd/command_reply.c.
2675 * A bit stricter check for nicknames. Check for same nickname
2676 in NICK command also. Affected file silcd/command.c.
2678 * Do not call INFO command everytime client ID changes, only
2679 during first connecting. Affected file lib/silcclient/client.c.
2681 * Set the new nickname only after successful command reply for
2682 NICK command is returned by server. Affected file
2683 lib/silcclient/command.c.
2685 * Remove nicknames from nicklist during server_signoff notify.
2686 Should fix /NAMES bit more. The affected file is
2687 irssi/src/silc/core/silc-channels.c.
2689 * Added `fingerprint' field to the SilcIDListData in the
2690 silcd/idlist.h to hold the fingerprint of the client's
2693 Send the fingerprint of the client's public key in WHOIS
2696 Affected files silcd/command.c, and silcd/idlist.[ch].
2698 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2699 create fingerprint from given data.
2701 * Show the fingerprint of the client's public key in WHOIS.
2702 Affected files irssi/src/module-formats.[ch] and
2703 irssi/src/silc/core/client_ops.c.
2705 * Format the multiple same nicknames also during JOIN and
2706 NICK_CHANGE notifys. Affected file is
2707 lib/silcclient/client_notify.c.
2709 * Do not print error on screen for invalid private message
2710 payload since it can come if someone is sending private
2711 messages with wrong key. Affected file
2712 lib/silccore/silcprivate.c.
2714 * Fixed multiple concurrent /PING crash. Affected file
2715 lib/silcclient/command.c.
2717 * Changed the wrong ID encoding. All IP addresses must be
2718 in MSB first order in encoded format. They were encoded
2719 wrong and was in LSB format. Affected files are
2720 silcd/serverid.c, lib/silcutil/silcutil.c.
2722 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2724 * Call the `connect' client operation through the scheduler
2725 in case of error. Affected file lib/silcclient/client.c.
2727 * Call the `failure' client operation even if the error
2728 occurred locally during a protocol. Affected file is
2729 lib/silcclient/protocol.c.
2731 * Added support of sending LIST command to router from normal
2732 server. This way normal server can get list of all channels
2733 in the network too. Fixed the channel list sending in the
2734 server too. Affected files are silcd/command.c, and
2735 silcd/command_reply.[ch].
2737 * Added silc_server_update_channels_by_server and
2738 silc_server_remove_channels_by_server. They are used during
2739 disconnection of primary router and in backup router protocol.
2740 Affected file silcd/server_util.[ch], silcd/server.c and
2741 silcd/server_backup.c.
2743 * Fixed channel adding to global list in IDENTIFY command
2744 reply in server. Affected file silcd/command_reply.c.
2746 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * If the incoming packet type is REKEY or REKEY_DONE process
2749 that packet always synchronously. Fixes yet another MAC
2750 failed error on slow (dialup) connections. Affected file
2751 lib/silcclient/client.c and silcd/server.c.
2753 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Call check_version SKE callback for initiator too. Affected
2756 file lib/silcske/silcske.c.
2758 * Implemented fix for security hole found in the SKE that was
2759 fixed in the specification few days back; the initiator's
2760 public key is now added to the HASH value computation.
2761 Added backwards support for the old way of doing it too, for
2762 old clients and old servers. Affected file is
2763 lib/silcske/silcske.c.
2765 * Enabled mutual authentication by default in SKE. If initiator
2766 is not providing mutual authentication the responder will
2767 force it. This will provide the proof of posession of the
2768 private key for responder. The affected files are
2769 lib/silcclient/protocol.c and silcd/protocol.c.
2771 * Do not cache anymore the server's public key during SKE.
2772 We do mutual authentication so the proof of posession of
2773 private key is done, and if the server is authenticated in
2774 conn auth protocol with public key we must have the public
2775 key already. Affected file silcd/protocol.c.
2777 * Added new global debug variable: silc_debug_hexdump. If
2778 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2779 file lib/silcutil/silclog.[ch].
2781 * Fixed compilation warning due to char * -> const char *.
2782 Affected files lib/silcutil/silcnet.h, and
2783 lib/silccore/silcauth.[ch].
2785 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Fixed CMODE command when new channel key was created. If
2788 the creation failed the old key was removed. Next time giving
2789 same command would crash the server since the old key was
2790 freed already. Affected file silcd/command.c.
2792 * Fixed the silc_server_announce_get_channels to not crash
2793 on reconnect. Affected file silcd/server.c.
2795 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Added silc_log_set_debug_string function to set a regex
2798 string to match for debug output. Only the function names,
2799 or filenames matching the given debug string is actually
2800 printed. This way it is possible to filter out those debug
2801 strings that user is not interested in.
2803 Fixed a bug in silc_string_regexify.
2805 Affected files lib/silcutil/silclog.[ch], and
2806 lib/silcutil/unix/silcunixutil.c.
2808 * Changed the -d options in both server and Irssi SILC client
2809 to take the debug string as argument. Affected files
2810 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2812 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Added silc_hash_babbleprint to create a Bubble Babble
2815 Encoded fingerprint. The encoding is developed by Antti
2816 Huima (draft-huima-babble-01.txt), and it creates human
2817 readable strings out of binary data. Affected file
2818 lib/silccrypt/silchash.[ch].
2820 * Print the babble print now in addition of fingerprint as well
2821 in Irssi SILC client. Affected files are
2822 irssi/src/fe-common/silc/module-formats.[ch],
2823 irssi/src/fe-common/silc/core/client_ops.c.
2825 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Fixed a security problem found in SKE. The initiator's
2828 public key too is now added to the HASH hash value creation
2829 which is signed by the responder to create the SIGN value.
2830 This will prevent anyone in the middle to lie to the responder
2831 about the initiator's public key. If this is done now, the
2832 man in the middle will get caught. Updated the protocol
2835 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Better installation directory handling. Configure module
2838 paths and other paths automatically to example_silc* files
2839 in doc/. A patch by toma.
2841 * Fixed compiler warning from MPI library, and from SILC RNG.
2844 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2845 It can be configured with ./configure. A patch by toma.
2847 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2849 * Find correct make to use in prepare-clean. A patch by
2850 toma. Affected file prepare-clean.
2852 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2854 * Added irssi variables use_auto_addr, auto_bind_ip,
2855 auto_bind_port and auto_public_ip.
2857 * Changed the interface for silc_client_send_key_agreement
2858 in lib/silcclient/silcapi.h
2862 irssi/src/silc/core/silc-core.c
2864 lib/silcclient/silcapi.h
2865 irssi/src/silc/core/silc-channels.c
2866 lib/silcclient/client_keyagr.c
2869 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Added silc_pkcs_public_key_compare to compare two
2872 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2874 * Check that the client who set the founder mode on the
2875 channel is the same client that is giving the founder
2876 mode to itself. It is done by comparing the saved public
2877 key (it is saved even in the authentication is passphrase).
2878 Affected file silcd/command.c.
2880 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Do not process packet for disconnected socket connection.
2883 Affected file lib/silccore/silcpacket.c.
2885 * Process the DISCONNECT packet through scheduler in the
2886 client library. Affected file lib/silcclient/client.c.
2888 * Fixed the silc_client_packet_parse to not to increase
2889 the packet sequence number if the conn->sock and the
2890 current socket connection is not same. This can happen
2891 for example during key agreement when the conn includes
2892 multiple socket connections (listeners). Affected file
2893 lib/silcclient/client.c.
2895 * The sender of the file transfer request now provides also
2896 the pointer (listener) for the key exchange protocol. If
2897 the listener cannot be created then it sends empty key
2898 agreement and lets the receiver provide the listener.
2900 Added `local_ip' and `local_port' arguments to the
2901 silc_client_file_send. If they are provided they are used,
2902 if not then it will attempt to find local IP address, if
2903 not found or bind fails then the remote client will provide
2906 Affected files are lib/silcclient/client_ftp.c and
2907 lib/silcclient/silcapi.h.
2909 * Extended the FILE SEND command to support defining the
2910 local IP and port for key exchange listener. They are
2911 optional. Affected file irssi/src/silc/core/silc-servers.c.
2913 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Defined to WHOIS command reply the sending of fingerprint
2916 of the client's public key (if the proof of posession of the
2917 corresponding private key is verified by the server).
2918 Updated to the protocol specification.
2920 * Added support of receiving the client's public key's
2921 fingerprint in command reply in client library. Affected
2922 file is lib/silcclient/command_reply.c, and
2923 lib/silcclient/idlist.[ch].
2925 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Do not send over 128 chars long nickname to the server
2928 in NICK command. Affected file lib/silcclient/command.c.
2930 * Do not send over 256 chars long channel names to the server
2931 in JOIN command. Affected file lib/silcclient/command.c.
2933 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Assure that silc_server_close_connection cannot be called
2936 twice for same socket context. Affected file is
2939 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Send error message to application if opening file for
2942 writing during file transfer fails. Affected file is
2943 lib/silcclient/client_ftp.c.
2945 Remove all file transfer sessions for a client that we're
2946 removing from ID cache.
2948 Affected file is lib/silcclient/client_ftp.c.
2950 * Fixed silc_net_addr2bin to return correct address. Affected
2951 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2953 * Fixed file transfer session removing on signoff notify.
2954 Affected file irssi/src/silc/core/silc-servers.c.
2956 * Added the SilcClientFileError to be returned in the monitor
2957 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2958 Affected file lib/silcclient/silcapi.h.
2960 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Fixed a crash in silc_client_ftp_free_sessions and
2963 silc_client_ftp_session_free_client. Affected file
2964 lib/silcclient/client_ftp.c.
2966 * Added `disabled' field in the SilcChannelEntry in the server
2967 to indicate if the server entry is disabled. Affected file
2968 silcd/idlist.h, silcd/command[_reply].c.
2970 * SILC server adds now /var/run/silcd.pid everytime it is
2971 started. Affected file silcd/silcd.c.
2973 * Added silc_server_packet_send_clients to send a packet to
2974 the provided table of client entries. Affected file
2975 silcd/packet_send.[ch].
2977 * Fixed a crash in client resolving in client_prvmsg.c in
2978 client library. Affected file lib/silcclient/client_prvmsg.c.
2980 * Do not actually remove the client directly from ID cache
2981 during SERVER_SIGNOFF, but invalidate it. This way we
2982 preserve the WHOWAS info for the client. Affected file
2983 silcd/server_util.c.
2985 * Fixed SERVER_SIGNOFF notify handling in the server. The
2986 server is now able to process incoming SERVER_SIGNOFF notify
2987 for a server that it doesn't even know about. It will remove
2988 the clients provided in the notify. Affected file
2989 silcd/packet_receive.c.
2991 * Check for partial packet in data queue after every packet that
2992 was found from the queue. Return and wait for more data if
2993 there is partial data in queue. Affected file is
2994 lib/silccore/silcpacket.c.
2996 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Added SilcClietFileError enum to indicate error in
2999 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3000 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3001 Affected files lib/silcclient/silcapi.h and
3002 lib/silcclient/client_ftp.c.
3004 * Check that newsize in silc_buffer_realloc is larger than
3005 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3007 * Added better monitor of file transfers. It now monitors
3008 key agreement protocol during the file transfer too. Added
3009 error reporting too. Affected files
3010 irssi/src/silc/core/silc-servers.c,
3011 irssi/src/fe-common/silc/module-formats.[ch].
3013 * Wrote a help file for FILE command.
3015 * Added silc_rng_global_get_byte_fast to get not-so-secure
3016 random data as fast as possible. Random data is read from
3017 /dev/urandom if available and from the SILC RNG if not
3018 available. It is used in padding generation. Affected file
3019 lib/silccrypt/silcrng.[ch].
3021 * All packets in client library are now processed synchronously.
3022 Optimized packet processing a lot. Affected file
3023 lib/silcclient/client.c.
3025 * All server connection packets are processing synchronously
3026 now in server, to optimize packet processing. Affected file
3029 * Include files are installed now only in Toolkit distribution
3030 if make install is given. Affected files: all Makefile.am's.
3032 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Assure that silc_client_notify_by_server_resolve does not
3035 resolve the client information multiple times. If it cannot
3036 be found by the first it cannot be found at all. Affected
3037 file lib/silcclient/client_notify.c.
3039 * Fixed WHOWAS command reply calling. Affected file
3040 lib/silcclient/command_reply.c.
3042 * Removed all references to silc_idlist_get_client from the
3043 Irssi SILC client since that call is internal call used by
3044 the library. The Irssi SILC client will use now client
3045 retrieval functions found in silcapi.h.
3047 * Fixed a bug in resolving nickname info before sending
3048 private message. It used freed memory. Affected file
3049 irssi/src/silc/core/silc-servers.c.
3051 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Assure my_channels statistics cannot go negative in server.
3054 Affected files silcd/server.c, silcd/server_util.c.
3056 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3066 lib/sftp/sftp_fs_memory.c.
3068 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Added silc_net_localip to return local host's IP address.
3071 Affected file lib/silcutil/silcnet.[ch].
3073 * If key exchange or rekey protocol is active for a connection
3074 parse all packets syncronously since there might be packets
3075 in packet queue that we are not able to process without first
3076 processing packets before them. Affected file silcd/server,
3077 lib/silcclient/client.c.
3079 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3080 whether library should continue processing the packet.
3081 Affected file lib/silccore/silcpacket.h.
3083 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3084 SilcSFTPMonitorData to SFTP server to monitor various

3092 Added preliminary support for simple client to client one-file
3093 transmission. Affected file lib/silcclient/client_ftp.c,
3094 lib/silccilent/client.[ch].
3096 * Added new local command FILE to the Irssi SILC Client.
3097 It is used to perform the file transfer. It has subcommands
3098 SEND, RECEIVE, SHOW and CLOSE. Affected files
3099 irssi/src/silc/core/client_ops.c,
3100 irssi/src/silc/core/silc-server.[ch].

3104 * Relay the SILC_PACKET_FTP in the server. Affected files
3105 silcd/server.c and silcd/packet_receive.c.
3107 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Renamed silc_file_read and silc_file_write to functions
3110 silc_file_readfile and silc_file_writefile. Added function
3111 silc_file_open and silc_file_close. Affected files
3112 lib/silcutil/silcutil.[ch].
3114 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Resolve the client info when received private message or
3117 channel message for a client which nickname we don't know.
3118 Affected files lib/silcclient/client_prvmsg.c and
3119 lib/silcclient/client_channel.c.
3121 * Do not crash in /KEY if client is not connected. Affected

3127 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3128 is incomplete and is being resolved, it won't be resolved
3131 Make sure also that USERS command reply does not resolve
3132 twice information. Affected file is
3133 lib/silcclient/command_reply.c.
3135 Make sure that silc_client_get_clients_by_list does not
3136 resolve twice same information.
3138 * Check for valid client->id in the silc_server_free_client_data.
3139 Affected file silcd/server.c.
3141 * Fixed /GETKEY nick@server not to crash if the server entry
3142 is not found. Affected file lib/silcclient/command.c.
3144 * Fixed the silc_server_check_cmode_rights to check the
3145 requested modes correctly. Affected file silcd/command.c.
3147 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Better checks for non-printable chars in nick added.
3150 Affected file silcd/command.c.
3152 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Call the silc_server_udpate_servers_by_server in the
3155 primary router that comes back online in the backup resuming
3156 protocol. Otherwise it routes packets wrong. Affected file
3157 silcd/server_util.[ch], silcd/server_backup.c.
3159 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3162 lib/silcutil/silcbuffmt.[ch].
3164 * Redefined the SILC packet header to include the padding
3165 length. Affected file lib/silccore/silcpacket.[ch].
3167 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3168 length for maximum padding up to 128 bytes). Affected
3169 file lib/silccore/silcpacket.h.
3171 * Removed all backwards support for old 0.5.x MAC thingies.
3172 The SILC packet header change makes it impossible to be
3173 backwards compatible.
3175 * Send the ENDING packet with timeout in the backup resuming
3176 protocol. This is to assure that all routers has connected
3177 to the primary router. Affected file silcd/server_backup.c.
3179 * Changed the RNG to take the first IV from random data. It
3180 used to take it from zero actually. Changed the RNG also
3181 to use /dev/urandom during session. /dev/random is used
3182 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3184 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * Changed the SILC packet header to have the first two bytes
3187 (the packet length) encrypted. Affected files aroung the
3188 code tree, lib/silccore/silcpacket.[ch]. Removed the
3189 SilcPacketCheckDecrypt callback. It is not needed anymore
3190 since the silc_packet_receive_process will determine now
3191 whether the packet is normal or special.
3193 * Implemented the unidirectional MAC keys. Affected files
3194 lib/silcske/silcske.c, silcd/protocol.c and
3195 lib/silcclient/protocol.c.
3197 * Implemented the packet sequence number to the MAC computation.
3198 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3199 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3200 lib/silcclient/protocol.c.
3202 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Allow backup router to announce servers. All servers
3205 announced by backup router are added to the global list
3206 automatically. Update hte server's socket to our primary
3207 router also when backup router announces a server.
3208 Affected file silcd/packet_receive.c.
3210 * Do not update the client->router in the function
3211 silc_server_udpate_clients_by_server if the client is on
3212 global list. We might fail to find any specific server
3213 for locally connected clients and local cell clients. They
3214 should still use the `from' and not `to' as client->router.
3215 This fixes backup router resuming protocol. Affected file
3216 silcd/server_util.c.
3218 * Decrease channel statistics count only if the channel
3219 deletion worked. Affected files are silcd/server.c and
3220 silcd/server_util.c.
3222 * Added silc_server_update_servers_by_server to update origin
3223 of all server entries. Used during backup router protocol.
3224 Affected files silcd/server_util.[ch], silcd/server.c. and
3225 silcd/backup_router.c.
3227 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3228 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3229 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3230 lib/silccrypt/silchmac.c.
3232 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Assure that router cannot reroute the same channel message
3235 to the sender. Affected file silcd/packet_receive.c.
3237 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Made better checks that the channel message is not sent
3240 to the router it came from. Affected file is
3241 silcd/packet_send.c. Fixed memory leak too.
3243 * Announce informations for incoming router connection, but
3244 only after checking if it is replaced by backup router.
3245 Affected file silcd/packet_receive.c.
3247 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Fixed the backup resuming protocol to work in multiple
3250 router environment. Affected file silcd/server_backup.c.
3252 * Route packet only to one router in the function
3253 silc_server_packet_send_to_channel. Affected file is
3254 silcd/packet_send.c.
3256 * Fixed silc_server_send_notify_dest to set the broadcast
3257 flag. Fixed the silc_server_send_notify_topic to actually
3258 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3259 Affected file silcd/packet_send.c.
3261 * Changed the SFTP Filesystem interface. Changed the
3262 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3263 the filesystem operation function. The SilcSFTPFilesystem
3264 is now a context that is allocated by all filesystem allocation
3265 functions and it already includes the operations structure
3266 and filesystem specific context. It is given as argument
3267 now to the silc_sftp_server_start. This made the interface
3268 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3269 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3271 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Changed the backup router adding and getting interfaces
3274 in the server. The router that will be replaced by the
3275 specified backup router is now sent as argument. Affected
3276 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3279 * Added silc_net_addr2bin_ne to return the binary form of
3280 the IP address in network byte order. Affected files
3281 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3283 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3285 * Check for existing server ID in silc_server_new_server
3286 and in silc_server_connect_to_router_final and remove the
3287 old entry if it exists. Affected file silcd/packet_receive.c,
3290 * Send the channel message always to only one router, either
3291 in upstream or downstream. Affected file is
3292 silcd/packet_send.c.
3294 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Wrote the definition of the backup resuming protocol to the
3297 protocol specification.
3299 * Removed one redundant channel key generation from normal
3300 server during joining procedure. Removed one redundant
3301 channel key sending from server to router during joining
3302 procedure. Affected file silcd/command.c.
3304 * Made minor bugfixes to the backup router resuming protocol.
3305 Affected file silcd/server_backup.c, server.c.
3307 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3309 * Added --disable-asm configuration option. Affected files
3310 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3313 * Implemented the backup resuming protocol that is used to
3314 resume the primary router position in the cell after the
3315 primary router comes back online. Affected files
3316 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3317 and silcd/server_util.[ch].
3319 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Sleep two (2) seconds after sending QUIT command to server.
3322 Affected file lib/silcclient/command.c.
3324 * Assure that if outgoing data buffer is pending do not force
3325 send any data. Affected file silcd/packet_send.c.
3327 * Assure that if outgoing data buffer is pending do not force
3328 send any data. Affected file lib/silcclient/client.c.
3330 * Implemented the backup router support when the primary router
3331 goes down. The servers and routers can now use the backup
3332 router as new primary router without loosing connectivity.
3334 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3337 in the server to indicate disabled entry. All data read
3338 from the connection will be ignored and no data is sent
3339 for entry that is disabled. Affected files are
3340 silcd/idlist.h, silcd/server.c.
3342 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Created SFTP client and server test programs in the
3345 lib/silcsftp/tests directory.
3347 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Implemented memory filesystem (virtual filesystem) for
3350 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3353 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Implemented the SFTP (SSH File Transfer Protocol) to the
3356 lib/silcsftp. It includes SFTP client and SFTP server
3359 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Moved lib/silccore/silcprotocol.[ch] to the
3362 lib/silcutil library.
3364 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3365 take variable argument list pointer as argument. Affected
3366 file lib/silcutil/silcbuffmt.[ch].
3368 * Added silc_buffer_set function that is used to set data
3369 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3370 Affected file lib/silcutil/silcbuffer.h.
3372 * Changed various routines in the core library to use the new
3373 silc_buffer_set instead of allocating new buffer only for
3376 * Added 64-bit value formatting and unformatting support to the
3377 silc_buffer_[un]format routines. Affected file is
3378 lib/silcutil/silcbuffmt.[ch].
3380 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3381 to includes/bitmove.h.
3383 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Fixed channel user mode saving in client library. Affected
3386 file lib/silcclient/command[_reply].c.
3388 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Defined the file transfer to the SILC Protocol. Added
3391 new packet type SILC_PACKET_FTP and defined File Transfer
3392 Payload. The mandatory file transfer protocol is SFTP
3393 (SSH File Transfer Protocol). Affected file in addition
3394 of the internet draft is lib/silccore/silcpacket.h.
3396 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3397 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3398 is used as part of backup router protocol when the primary
3399 router of the cell is back online and wishes to resume
3400 the position as primary router.
3402 * Redefined the MAC generation keys in the protocol. The
3403 same key is not used anymore in both direction. Both
3404 direction will now use different keys for sending and
3405 receiving. This fixes a potential security flaw. This
3406 change causes incompatibilities in the protocol.
3408 * Redefined also the MAC computation from the packet.
3409 An packet sequence number is now added to the MAC
3410 computation. This prevents possible replay attacks against
3411 the protocol. This change too causes incompatibilities
3414 Added `sequence' field to the SilcPacketContext to hold
3415 the current sequence number for the packet.
3417 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Added `created' field to the SilcIDListData in the file
3420 silcd/idlist.h to indicate the time when the entry was
3423 * Added `created' field to the SilcChannelEntry too. Affected
3424 file silcd/idlist.h.
3426 * Added `creation_time' aguments to all the announcement functions
3427 in the server. If it is provided then only the entries that
3428 was created after the provided time frame are actually
3429 announced. Affected file silcd/server.[ch].
3431 * The protocol says that the Channel ID's IP address must be
3432 based on the router's IP address. Added check for this in
3433 the silc_server_new_channel when processing incoming New Channel
3434 Payload. Affected file silcd/packet_receive.c.
3436 * Print out the correct version with --version in SILC client.
3437 Affected file irssi/src/silc/core/silc-core.c.
3439 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Fixed WHOWAS command to check for completnes of the client
3442 entry always, not just when the command is coming from client.
3443 Affected file silcd/command.c.
3445 * Added new function silc_server_packet_queue_purge to purge the
3446 outgoing data queue to the network. After the function returns
3447 it is guaranteed that the outgoing packet queue is empty.
3448 Affected file silcd/packet_send.[ch].
3450 * Purge the outgoing packet queue in the rekey protocol's final
3451 callback to assure that all rekey packets go to the network
3452 before quitting the protocol. Affected file silcd/server.c.
3454 * Added silc_client_packet_queue_parse as similar function as
3455 in server to the client library. The affected file is
3456 lib/silcclient/client.c.
3458 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3460 * Splitted silcd/server.c and created silcd/server_util.[ch]
3461 for utility functions.
3463 * Added new socket flag SILC_SF_DISABLED to indicate that the
3464 connection is open but nothing can be sent to or received from
3465 the connection. Affected file lib/silcutil/silsockconn.[ch].
3466 The checking for disabled socket is checked in the low level
3467 silc_socket_write and silc_socket_read functions.
3469 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3471 * Allow only nicknames and channel names that fits into the
3472 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3474 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * When processing JOIN command reply in server check that if
3477 the channel exists in our global list we'll move it the local
3478 list. Affected file silcd/command_reply.c.
3480 * Fixed the check whether client is joined on the channel already
3481 in JOIN command. Affected file lib/silcclient/command.c.
3483 * Fixed the JOIN command reply to check whether the channel
3484 already exists. Affected file lib/silcclient/command_reply.c.
3486 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Added silc_ske_status_string to map the SKE error numbers
3489 to readable strings. The affected files are
3490 lib/silcske/silcske[_status].[ch].
3492 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Do not show the private channels on the WHOIS channel list
3495 as it is not allowed by the protocol. The affected file is
3498 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Assure that the packet length digged from the actual packet
3501 is something sensible in the silc_packet_decrypt_rest_special
3502 in lib/silccrypt/silcpacket.c.
3504 * Free and NULL the allocated pointer in silc_hmac_alloc if
3505 the HMAC allocation fails. The affected file is
3506 lib/silccrypt/silchmac.c.
3508 * Print the selected security properties to the log files in
3509 the server. Affected file silcd/protocol.c.
3511 * Add SKE's reference counter even if calling the completion
3512 callback manually. Otherwise it goes negative, although it
3513 does not cause any problems. The affected file is
3514 lib/silcske/silcske.c.
3516 * Remove the client entry with short timeout after giving the
3517 KILL command. Affected file lib/silcclient/command.c.
3519 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3520 case all found clients are already disconnected (WHOWAS would
3521 found them) in the server. Affected file silcd/command.c.
3523 * Update the last_receive (time of last data received) to be
3524 updated only when received private or channel message so that
3525 the idle time showed in WHOIS makes more sense.
3527 * Added boolean field `valid' in to the SilcClientEntry in the
3528 client library to indicate whether the entry is valid or not.
3529 This fixes the nickname change bug on channel when changing
3530 the nickname to be same than the old (like nick to Nick) the
3531 nickname formatter doesn't set the new nick anymore to Nick@host.
3532 Affected file lib/silcclient/idlist.[ch].
3534 * Now actually fixed the nickname changing on disconnection.
3535 Added new function silc_change_nick to the Irssi SILC Client.
3536 Affected file irssi/src/silc/core/client_ops.c,
3537 irssi/src/silc/core/silc-nicklist.[ch].
3539 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Check that the public key exists in the GETKEY command before
3542 trying to encode it. Affected file silcd/command.c.
3544 * Print some notifications on received public keys with GETKEY
3545 command in the Irssi SILC Client. Affected files are
3546 irssi/src/fe-common/silc/module-formats.[ch],
3547 irssi/src/silc/core/client_ops.c.
3549 * Use IDENTIFY command to resolve the server information in the
3550 GETKEY command instead of INFO command. Affected file
3551 lib/silcclient/command.c.
3553 * All command reply functions in the client library now calls
3554 the pending command reply callbacks even if an error has
3555 occurred. The server has done this a long time and now it was
3556 time to move the client library to this as well. Now all
3557 errors can be delivered back to the pending command reply
3558 callbacks if necessary. Affected files are
3559 lib/silcclient/command[_reply].[ch].
3561 * Change the nickname on disconnection back to the username
3562 because in reconnect the server will enforce it to it anyway.
3563 Affected file irssi/src/silc/core/silc-servers.c.
3565 * Fixed a config file parsing bug in the Irssi SILC client.
3566 Affected file irssi/src/silc/core/clientconfig.c.
3568 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * When printing the channel mode on JOIN, verify that the
3571 channel key and channel's HMAC are valid. Affected file
3572 irssi/src/silc/core/client_ops.c.
3574 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3577 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3578 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3580 * Removed channel key rekey task deleting from the function
3581 silc_server_save_channel_key. Affected file silcd/server.c.
3582 Added explicit timeout task context instead that is used to
3583 delete the task if we are registering a new task before the
3584 new task has elapsed.
3586 * When channel key rekey occurs the client library now saves
3587 the old channel key for a short period of time (10 seconds) and
3588 is able to use it in case some is still sending channel
3589 messages encrypted with the old key after the rekey. Affected
3590 file lib/silcclient/[idlist.h|client_channel.c].
3592 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Added check to the silc_server_new_id_real to not accept
3595 new ID if it is the sender's own ID. Affected file is
3596 silcd/packet_receive.c.
3598 * Assure that we do not announce ourself or the one we've
3599 sending our announcements when we're router and are announcing
3600 servers to our primary router. Affected file silcd/server.c.
3602 * Fixed silc_server_command_identify_check_client to assemble
3603 correct WHOIS packet. It send corrupted WHOIS packet and
3604 caused problem with router to router connections. Affected
3605 file silcd/command.c.
3607 Fixed also silc_server_command_whois_check the same way
3608 as for the IDENTIFY command.
3610 * Added new SilcIDListStatus to the server in the SilcIDListData
3611 structure. The status now includes the current status of
3612 the entry (like registered, resolved etc.). Affected file
3613 silcd/idlist.[ch]. Defined a bunch of different status types
3614 as well. This replaced the old boolean registered field as well.
3616 Added resolve_cmd_ident field to the SilcClientEntry structure
3617 too so that if the entry is for example being resolved so
3618 another command may attach to the same pending command reply
3619 without requiring to resolve the same entry again. This concept
3620 should optimize the WHOIS and the IDENTIFY resolving under
3621 heavy load by taking away unnecessary resolving for entries
3622 that are being resolved already.
3624 Added support for adding multiple pending commands for one
3625 command idenfier. Affected file silcd/command[_reply].[ch].
3627 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3628 before deleting the data. Otherwise the hash table will have
3629 freed data in comparison functions. Affected file is
3630 silcd/command_reply.c.
3632 * Fixed silc_idlist_replace_client_id to add the new entry to
3633 the cache with NULL nickname. Otherwise there will be invalid
3634 memory as the nickname after the nickname is freed. Affected
3635 file silcd/packet_receive.c.
3637 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3638 saved into wrong slots because the previous number of entries
3639 was not taken into account. Affected file silcd/idlist.c.
3640 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3642 * If we are router and we receive JOIN notify to a channel that
3643 does not have any users then notified client is marked as the
3644 channel founder, as it is it. The affected file is
3645 silcd/packet_receive.c
3647 * Added to the extended hash table API's table_del_*ext functions
3648 the destructor as argument too, so that the caller can decide
3649 which destructor to use or whether to use destructor at all.
3650 Affected file lib/silcutil/silchashtable.[ch].
3652 * Fixed ID Cache purging. It actually deleted the entries from
3653 the hash table after the data was freed. The hash table ended
3654 up comparing freed memory. The affected file is
3655 lib/silccore/silcidcache.c.
3657 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Fixed Irssi SILC client's KILL command's HELP syntax.
3661 * The USERS command now resolves the detailed user information
3662 if the userinfo field is missing. Affected file is
3663 lib/silcclient/command_reply.c.
3665 * Do not print error in silc_file_read if the read file does
3666 not exist. Just silently return NULL. Affected file is
3667 lib/silcutil/silcutil.c.
3669 * Fixed the silc_log_output to not wine about NULL filename
3670 and to not create some bogus " " filename. Affected file is
3671 lib/silcutil/silclog.c.
3673 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Fixed various printing bugs on the user interface in the
3676 Irssi SILC Client. Minor changes that were forgotten from
3679 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3681 * Fixed the configure.in.pre and the compilation and distribution
3682 environment to support the new autoconf 2.52. That version is
3683 now required to compile the CVS trunk.
3685 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3688 to generally parse user@fqdn format strings. Affected file
3689 lib/silcutil/silcutil.c.
3691 * Added nickname_format and nickname_force_format fields to the
3692 SilcClientParams structure. The first one defines the format
3693 for the nicknames that the library will enforce if the receives
3694 multiple same nicknames. The second one is boolean value and
3695 can be used to force the library to always enforce the format
3696 to the nicknames regardles whether there are multiple nicknames
3697 or not. This configurable formatting was employed to flexibly
3698 support accessing multiple nicknames from the user interface.
3699 The userinterface can now set the nicknames to what ever format
3700 they prefer. Affected file lib/silcclient/silcapi.h.
3702 Added function silc_client_nickname_format to the file
3703 lib/silcclient/idlist.c. It performs the nickname formatting.
3705 Added new field `hostname´ to the SilcClientEntry context.
3706 It holds the hostname of the client. Affected file is
3707 lib/silcclient/idlist.h.
3709 * Irssi SILC Client sets the nicknames in nick@hostn format.
3710 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3711 irssi/src/silc/core/silc-core.c.
3713 The WHOIS printing now also shows both the real nickname and
3714 the formatted nickname so that user knows how to access the
3715 user if there are multiple same nicknames cached. Affected
3716 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3717 printing formatting too to take the hostname now as a separate
3718 argument. The Affected file is
3719 irssi/src/fe-common/silc/modules-formats.[ch].
3721 * Changed the silc_client_get_clients_local to accept the formatted
3722 nickname as argument. It accepts the real nickname too but the
3723 formatted nickname can be used to find the true entry from
3724 multiple entries. Affected file lib/silcclient/silcapi.h and
3725 lib/silcclient/idlist.c.
3727 * Added nickname_format_parse field to the SilcClientParams.
3728 It is a callback function provided by the application to parse
3729 the nickname out of the formatted nickname string. The library
3730 calls it to get the nickname from the formatted string. Since
3731 the application generally knows better the format of the nickname
3732 string it parses it instead of the library, even though library
3733 encodes the formatted string. If the callback function is not
3734 provided then the library will use the string as is. The
3735 affected file is lib/silcclient/silcapi.h.
3737 * All the nickname strings passed to the client library in
3738 commands are now expected to be formatted nickname strings.
3739 If the command does not support the formatted nickname string
3740 it will assume that the sent string is the actual nickname.
3741 Affected file lib/silcclient/command.c.
3743 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Added public key authentication support to OPER and SILCOPER
3746 commands in the client library. Affected file is
3747 lib/silcclient/command.c.
3749 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Changed the get_auth_methdod client operation to be asynchronous.
3752 It can be async if the application resolves the authentication
3753 method from the server during the negotiation. Added new
3754 SilcGetAuthMeth completion callback that the application will
3755 call after resolving the authentication method.
3757 Added function silc_client_request_authentication_method that
3758 the application can use to resolve the authentication method
3759 from the server. Added also SilcConnectionAuthRequest callback
3760 that the library will call after the server has replied. The
3761 application can call this function if it does not know the
3762 current authentication method.
3764 Affected files are lib/silcclient/client.c and
3765 lib/silcclient/silcapi.h.
3767 * The Irssi SILC client now automatically resolves the authentication
3768 method incase any configuration information is not present (and
3769 currently there never is). The affected file is
3770 irssi/src/silc/core/client_ops.c.
3772 * Fixed public key authentication from the client library.
3773 Affected file lib/silcclient/protocol.c. Changed also the
3774 protocol specification about the public key authentication in
3775 the connection authentication protocol. The actual data to be
3776 signed is now computed with a hash function before signing.
3778 * Fixed the public key authentication from the server as well.
3779 Affected file silcd/protocol.c.
3781 * Removed the mlock()'s from the memory allocation routines.
3782 Affected file lib/silcutil/silcmemory.c. The ./configure does
3783 not check anymore for the mlock(). Affected file is
3786 * Fixed USERS command in server to allow the execution of the
3787 command for private and secret channels if the client sending
3788 the command is on the channel. Affected file silcd/command.c.
3790 * Fixed silc_client_get_clients_local to return the clients
3791 count correctly. It could return wrong value. Affected file
3792 lib/silcclient/idlist.c.
3794 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3796 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3797 types. The assembler optimizations seemed not to like 64-bit
3798 data types. The assmebler optimizations thus are now enabled
3799 also for BSD systems as opposed to only enable them for Linux.
3801 * Do not check for threads at all on BSD systems. Affected
3802 file configure.in.pre.
3804 * Removed -n and -h options from the Irssi SILC Client since
3805 they are not used in silc.
3807 * Fixed the prime generation to assure that the first digit
3808 of the generated random number is not zero since our conversion
3809 routines does not like number strings that starts with zero
3810 digit. If zero digit is seen the random number is regenerated.
3811 This caused some corrupted RSA keys when the zero first digit
3812 was met. Affected file lib/silcmath/silcprimegen.c.
3814 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * Fixed WIN32 configuration in the ./configure script.
3817 Fixed to include xti.h on environments that has it.
3818 Patches by Carsten Ilchmann and andrew.
3820 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * Changed the silc_id_create_client_id to be collision
3823 resistant. It is now assured that there cannot be created
3824 two same client ID's. I suspect that some weird bugs in
3825 the server were actually caused by duplicate Client IDs.
3826 Affected file silcd/serverid.[ch]. A router receiving
3827 new ID now also assures and informs the sending server
3828 if the ID caused collision.
3830 * Changed the silc_id_create_channel_id to also assure that
3831 there are no collisions.
3833 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Statement about ignoring the Mutual Authentication flag when
3836 performing rekey with PFS was a bit misleading. It is ignored
3837 if it was set in the initial negotiation, it cannot be even
3838 set in the rekey. Fixed in the ke-auth draft. Started the
3839 new versions of the protocol drafts in the doc/.
3841 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Fixed a bug in silc_client_command_identify_save when saving
3844 new channel information. The channel name was no duplicated
3845 and caused crash on exit. Affected file is
3846 lib/silcclient/command_reply.c.
3848 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Fixed the getkey command handling in the server. Send just
3851 empty OK reply to the sender if the key could not be fetched
3852 (but everything else was ok, like the key just was not available).
3853 Changed the public key parameter to optional in the protocol
3854 specs so that empty OK reply can be sent. Affected file
3857 Added a message to Irssi SILC client to tell to user if the
3858 server did not return a public key.
3860 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3862 * Fixed a channel key regeneration bug. It registered new
3863 timeout tasks exponentially until all system resources were
3864 used. Affected file silcd/server.c.
3866 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Added the SILC Document generator to the scripts/silcdoc.
3869 It can be used to generate the Toolkit Reference Manual out
3870 of the source tree. Internally it will also use the RoboDoc
3871 generator now imported in util/robodoc.
3873 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3875 * Added couple of return's in rekey protocol if error orccurred
3876 during the protocol. The execution must be terminated.
3877 Affected file silcd/protocol.c. Also, terminate the protocol
3878 always with timeout.
3880 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * The client's Client ID was created initally from the wrong
3883 nickname (it could have been in format nick@host) in the
3884 silc_server_new_client. Affected file silcd/packet_receive.c
3886 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3888 * Added some SILC_LOG_ERROR's to various error conditions
3889 if client could not be added to ID cache. Affected files
3890 silcd/packet_receive.c and silcd/server.c.
3892 * When client's sock->user_data is freed, NULL also the
3893 client->router and client->connection pointers. Added check
3894 for these pointers being NULL to various places around the
3895 code. Affected file silcd/server.c.
3897 * Added client->data.registered == TRUE checks to various
3898 places around the code to assure that unregistered client's
3899 are not handled when it is not allowed. Affected file
3902 * Added `bool registered' fields to all
3903 silc_idlist_[server|client]_get_* routines to indicate whether
3904 the fetched client needs to be registered or not. Affected
3905 file silcd/idlist.[ch].
3907 * Add your own entry as registered to the ID cache in the
3908 server. Affected file server.c.
3910 * Fixed a bug in silc_server_new_server. The SilcServer was
3911 set as the new server's context instead of SilcServerEntry.
3912 This naturally caused some weird bugs.
3914 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3916 * Do not delete the channel rekey task when adding it
3917 for in silc_server_create_channel_key.
3919 * Changed the silc_server_create_channel_key to return
3920 TRUE or FALSE to indicate the success of the channel key
3923 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3925 * Fixed MSVC++ project files and added missing files to
3926 Makefiles under win32/.
3928 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Do not add TCP_NODELAY flag if the operating system
3931 does not have it defined. Affected files are
3932 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3934 * Fixed buffer overflow from Irssi SILC Client. Affected
3935 file irssi/src/fe-common/core/themes.c.
3937 * Fixed double free in client library in the file
3938 lib/silcclient/client.c when disconnecting from server.
3940 * Applied double free patch from cras to Irssi SILC client.
3941 Affected files irssi/src/core/[modules/expandos].c
3943 * Fixed the disconnection handling to Irssi SILC Client.
3944 The application must call silc_client_close_connection
3945 in ops->connect client operation in case of failure of
3946 the connection. Affected file is
3947 irssi/src/silc/core/client_ops.c.
3949 * Do not set sock->protocol to NULL in the function
3950 silc_client_close_connection after executing the protocol's
3951 final callback since the sock might not be valid anymore.
3952 Affected file lib/silcclient/client.c.
3954 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Do not enable SILC_THREADS if the linking with libpthread
3957 did not happen. Affected file configure.in.pre.
3959 * Added notion to protocol specification that server must
3960 verify the sent authentication payload with CMODE when
3961 setting the channel founder key. Implemented it to the
3962 server. Affected file silcd/command.c.
3964 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Added _EXTRA_DIST SILC distribution variable to the
3967 distributions file. It is used to conditionally add extra
3968 files or directories to the specific distribution. Affected
3969 files ./prepare, Makefile.am.pre and distributions.
3971 Removed the `_' from the start of the distribution names.
3974 * Added README.WIN32 for instructions to compile the Toolkit
3977 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Fixed a double free in disconnection in the server. Affected
3980 file is silcd/server.c.
3982 * Fixed the lib/silcske/groups.c to work now also with GMP
3983 MP library. The string conversion did not work when using
3984 specific base and the base is indicated in the string as well.
3986 * Created win32/ directory which now includes MSVC++ specific
3987 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3988 It will appear only in the toolkit distribution
3990 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3992 * Changed the key material distribution function in case when
3993 the hash output is too short. The data is now concatenated
3994 a bit differently than it used to. Made the change to the
3995 SKE protocol specification.
3997 * Added better GMP detection to configure.in.pre. A patch
4000 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Fixed a minor bug in SKE that might cause some problem on
4003 some platforms. Affected file lib/silcske/silcske.c.
4005 * Added the cookie checking for initiator in the SKE. It checks
4006 that the responder returns the sent cookie unmodified. The
4007 affected file is lib/silcske/silcske.c. Added new SKE
4008 error type INVALID_COOKIE that can be sent during the
4009 negotiation. Fixed some memory leaks as well.
4011 * Added the "invalid cookie" error message to Irssi SILC client's
4014 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Added `task_max' field to the SilcClientParams to indicate
4017 the maximum tasks the scheduler can handle. If set to zero,
4018 default values are used. Affected file lib/silcclient/silcapi.h.
4020 * Fixed memory leaks in silc_client_close_connection. Affected
4021 file lib/silcclient/client.c.
4023 * Added silc_client_del_client_entry to client library to free
4024 all memory of given client entry. Affected file is
4025 lib/silcclient/idlist.[ch].
4027 * Added new functions silc_client_del_channel and
4028 silc_client_del_server to delete channel and server entries.
4029 Affected file lib/silcclient/[silcapi.h/idlist.c].
4031 * Removed silc_client_del_client_by_id from silcapi.h.
4033 * Fixed the INFO command to return the server's own info
4034 correctly when querying by Server ID. Affected file is
4037 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Removed the non-blocking settings in WIN32 code in the
4040 silc_sock_[read/write] and added SleepEx instead. Affected
4041 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4042 of input data is now checked with FIONREAD and ioctlsocket.
4044 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Call silc_schedule_task_del_by_context in the
4047 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4048 Affected file lib/silccore/silcprotocol.c.
4050 * Call silc_protocol_cancel for active protocols in the
4051 silc_server_close_connection if the funtion
4052 silc_server_free_sock_user_data has not been called.
4053 Affected file silcd/server.c.
4055 * Generic tasks cannot be deleted using the del_by_fd
4056 task deleting function since generic tasks does not match
4057 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4059 * Added a notion to SILCOPER help file that the SILCOPER works
4060 only on router server, not on normal server.
4062 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Added for WIN32 support for the new scheduler as well.
4065 Affected file lib/silcutil/win32/silcwin32schedule.c.
4067 * Fixed the SHA1 implementation to work on various platforms.
4069 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4071 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4072 API. It is part of the scheduler now. Everything else is
4073 as previously but some functions has changed their names.
4074 Checkout the lib/silcutil/silcschedule.h for the interface.
4075 Updated all applications to use the new interface. Affected
4076 files are lib/silcutil/silcschedule.[ch].
4078 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Found a bug in the SKE implementation. The HASH value,
4081 specified by the protocol, was not computed correctly. The
4082 public key of the responder was not added to the computation
4083 even though it is mandatory. Affected file lib/silcske/silcske.c.
4084 This unfortunately causes incompatibilities with older
4085 clients and servers.
4087 * Added WIN32 specific network init and uninit functions:
4088 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4089 the Winsock2. Affected file lib/silcutil/silcnet.h and
4090 lib/silcutil/win32/silcwin32net.c.
4092 * Set the socket always to nonblocking mode on WIN32 after
4093 reading data or writing data. Affected file is
4094 lib/silcutil/win32/silcwin32sockconn.c.
4096 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Fixed various compilation problems under WIN32. Affected
4099 files lib/silcutil/win32/silcwin32thread.c and
4100 lib/silcutil/win32/silcwin32schedule.c.
4102 * Removed all _internal.h #includes from public header
4103 files. Internal headers must never be included from
4106 Removed also the lib/silcske/payload_internal.h file.
4108 * All include files that may be needed (public and some others
4109 included by the public headers) by application developers are
4110 now copied to the ./includes directory. It does not copy any
4111 internal headers. Affected file Makefile.defines.pre and all
4112 Makefile.am's under lib/ and subdirs.
4114 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4116 * Do not change the ~/.silc directory's permissions automatically.
4117 Affected file irssi/src/silc/core/clientutil.c.
4119 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4121 * Do not cancel the protocol in silc_server_close_connection
4122 it might cause recursion. Now cancelled in the function
4123 silc_server_free_sock_user_data. Affected file silcd/server.c.
4125 * Fixed the silc_server_remove_clients_by_server to regenerate
4126 the channel keys correctly finally. Added also new function
4127 silc_server_remove_clients_channels to actually do it.
4128 Affected file silcd/server.c.
4130 * Fixed the silc_server_new_channel to not crash by giving
4131 wrong router to the new channel. Affected file is
4132 silcd/packet_receive.c.
4134 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4136 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4137 which is given as argument to the silc_client_alloc now.
4138 It can be used to configure the client and set various parameters
4139 that affect the function of the client.
4141 * The USERS command in server did not check whether the channel
4142 is private or secret. Affected file silcd/command.c.
4144 * Added new argument to the USERS command in protocol specification.
4145 The USERS command now can take the channel name as argument
4146 as well. Added support for this in client and server and
4147 updated the protocol specs.
4149 * Completed the GETKEY command in client. It can be now used
4150 to fetch also servers public key not only some clients.
4151 Affected files lib/silcclient/command[_reply].c.
4153 * Added silc_client_get_server to return server entry by the
4154 server name. Affected files lib/silcclient/silcapi.h and
4157 * Redefined the IDENTIFY command in protocol specification to be
4158 more generic. It now can be used to query information about
4159 any entity in the SILC Network, including clients, servers and
4160 channels. The query may be based either the entity's name
4161 or the ID. Added support for this in both client and server.
4163 Affected files silcd/command.c and lib/silcclient/command.c
4164 and command_reply.c.
4166 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4167 the _from_client and _from_server functions. Affected file
4170 * Added silc_client_get_channel_by_id_resolve to the file
4171 lib/silcclient/silcapi.h to resolve channel information by
4172 its ID. Added also silc_client_get_channel_by_id that
4173 does not resolve it from the server.
4175 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4177 * Added SilcServerEntry context into the client library
4178 to represent one server. The INFO command now allocates
4179 these to save the resolved server info. For now on the
4180 client library will also keep information about servers,
4181 connected and resolved with INFO.
4183 The INFO command now allocates the SilcServerEntry context
4184 and saves the server info there. The COMMAND_REPLY in
4185 the INFO now returns the parameters to application in
4186 same order as defined in the protocol specification.
4188 The entries are cached in the client->server_cache.
4190 * The INFO command is now issued after received the Client ID
4191 from the server. Affected file lib/silcclient/client.c.
4193 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4194 to the application as the mode changer might be server.
4195 It is guaranteed that NULL is not returned anymore to the
4196 application. Affected file lib/silcclient/client_notify.c.
4198 The ID Type is now also passed to the application so that
4199 it can check whether the returned entry is SilcClientEntry
4202 Added new function silc_client_get_server_by_id to return
4203 the server entry by ID. Affected files are the
4204 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4206 * Do not create the channel in the Irssi SILC Client when issuing
4207 the JOIN command but when received the sucessful JOIN command
4208 reply. Otherwise the channel might get created even though we
4209 could not join it. The Affected file is
4210 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4212 * Fixed a channel joining bug in router. The router must also
4213 check the channel modes, invite and ban lists etc. when serving
4214 the JOIN command sent by normal server. Affected file is
4215 silcd/command.c. The router now resolves the client's
4216 information from the server who sent the JOIN command if it
4217 does not know it, and processes the JOIN command only after
4220 * Changed the SilcCommandCb to take new argument; void *context2.
4221 Affected file lib/silccore/silccommand.h
4223 The second argument in the command callbacks in the server now
4224 includes the SilcServerCommandReplyContext if the command was
4225 called as pending command callback from the command reply.
4226 Otherwise it is NULL. When called as pending the status of the
4227 command reply will be checked and if it was erronous the
4228 error will be sent to the original sender of the command.
4229 This way the client always receives the error messages even
4230 though the server was actually the one who received the error
4231 when it resent the command to router, for example. Affected
4232 files silcd/command[_reply].[ch].
4234 * Fixed sending WHOWAS command's error message to client if
4235 the requested client could not be found. It was missing.
4238 * Changed the CMODE and CUMODE commands reply arguments in the
4239 protocol specification. The Channel ID is now sent in both
4240 of the commands to identify the channel. Implemented this
4241 new feature to the client and server. Affected files
4242 lib/silcclient/command_reply.c and silcd/command.c.
4244 * Made better checks for invite and ban lists in the JOIN
4245 command in server. Affected file silcd/command.c.
4247 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4249 * The server now performs the incoming host IP/DNS lookup
4250 using the silc_socket_host_lookup and thus does not block
4251 the server anymore. Affected file silcd/server.c.
4253 * Completed the multi-thread support for SILC Scheduler in
4254 the lib/silcutil/silcschedule.c.
4256 * Fixed the configure.in.pre to detect the pthread correctly
4259 * Fixed a deadlock in silc_task_queue_wakeup in the file
4260 lib/silcutil/silctask.c.
4262 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4264 * Added new function silc_schedule_wakeup that is used in
4265 multi-threaded environment to wakeup the main thread's
4266 schduler. It needs to be used when a thread adds a new task
4267 or removes a task from task queues. After waking up, the
4268 scheduler will detect the task queue changes. If threads
4269 support is not compiled in this function has no effect.
4270 Implemented the wakeup mechanism to both Unix and WIN32
4271 systems. Affected files are lib/silcutil/silcschedule.[ch],
4272 lib/silcutil/unix/silcunixschedule.c and the
4273 lib/silcutil/win32/silcwin32schedule.c.
4275 * Added new function silc_task_queue_wakeup to wakeup the
4276 scheduler by the specified task queue. Affected file
4277 lib/silcutil/silctask.[ch].
4279 * The silc_socket_host_lookup_start now wakes up the scheduler
4280 after adding the timeout task. Affected file is
4281 lib/silcutil/silcsockconn.c.
4283 * The silc_socket_host_lookup is synchronous now if the threads
4284 support is not compiled in. However, the callback is still
4285 called asyncronously through the scheduler, anyway. Affected
4286 file lib/silcutil/silcsockconn.c.
4288 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4290 * Added new function silc_socket_host_lookup to perform
4291 asynchronous IP and FQDN lookups for the socket connection.
4292 Affected files lib/silcutil/silcsockconn.[ch].
4294 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4296 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4297 that may or may not compile the mutex support in.
4299 Changed the silc_mutex_alloc interface. It allocates the
4300 mutex now to the sent pointer and returns TRUE or FALSE.
4302 Affected file lib/silcutil/silcmutex.h.
4304 * Wrote the SILC Task Queue interface to support multi-threads.
4305 Affected file lib/silcutil/silctask.[ch].
4307 * Wrote the SILC Scheduler to support multi-threads. Affected
4308 file lib/silcutil/silcschedule.c.
4310 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4312 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4313 in lib/silcutil/win32/.
4315 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4317 * Defined SILC Mutex API and SILC Thread API and implemented
4318 them for Unix. Affected files are
4319 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4320 lib/silcutil/unix/silcunixmutex.c and
4321 lib/silcutil/unix/silcunixthread.c.
4323 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4325 * Fixed the silc_server_remove_clients_by_server's channel
4326 key re-generation. The hash table handling was incorrect
4327 and would not work with many channels. Affected file is
4330 * Fixed some memory leaks around the server code.
4332 * Rewrote the silc_server_get_users_on_channel to support IPv6
4333 based Client ID's. Affected file silcd/server.c.
4335 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4336 specification. However, a separate document must be written
4337 to define the detailed signing procedure and the payload
4338 associated with the flag. Defined the flag to the
4339 lib/silccore/silcchannel.h as well.
4341 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4343 * Changed the dynamic tables to static size tables in the
4344 lib/silccrypt/silchmac.c.
4346 * Removed GCC dependencies from the code. A patch by cras.
4348 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Do not show the error "Error receiving packet bla bla"
4351 in server if it really was not an error (-2 means that reading
4352 is pending). Affected file silcd/server.c.
4354 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Fixed a possible crash in silc_server_remove_clients_by_server
4357 in silcd/server.c. Fixed there also some memory leaks.
4359 * Fixed the silc_idlist_replace_client_id. It could replace
4360 wrong key in the hash table. Affected file silcd/idlist.c.
4362 * Do not check whether there are global users on the channel
4363 if the channel->global_users is FALSE. Affected functions
4364 silc_server_remove_from_one_channel and
4365 silc_server_remove_from_channels in silcd/server.c. Also,
4366 do not check if the removed client is local as we can be
4367 sure that global client was not removed from the channel
4368 and checking for global users is not needed.
4370 * The silc_server_remove_clients_by_server now re-generates
4371 the channel keys correctly for those channels that had
4372 clients removed from them. Affected file silcd/server.c.
4374 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Found the reason of random crashes in the server. We weren't
4377 ignoring the SIGPIPE signal (which can be sent in write())
4378 and it crashed the server. Affected file silcd/silcd.c.
4380 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Assure that sock->user_data is not NULL in the function
4383 silc_server_packet_send in silcd/packet_send.c.
4385 * Disconnect the remote connection if it could not be added
4386 to any ID lists in the server. The affected file is
4389 * Check in silc_server_packet_send[_real/dest] that the
4390 socket is not disconnecting and ignore the data if it is.
4391 Affected file silcd/packet_send.c.
4393 * Define inline to __inline on native WIN32 compilation.
4394 Affected file includes/silcwin32.h.
4396 * Added some explicit type casts for inline code since MSVC
4397 require them. Affected files lib/silcutil/silcbuffer.h,
4398 lib/trq/silcdlist.h and lib/trq/silclist.h.
4400 * Print warning in log files from now on if the packet
4401 decryption fails. Affected file silcd/server.c.
4403 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4405 * Changed the `say' client operation's interface to accept
4406 new `type' argument to indicate the type of the message sent
4407 by the library. The application may filter the library's
4408 messages according the type. The affected file is the
4409 lib/silcclient/silcapi.h.
4411 * Added two new functions to lib/silcclient/silcapi.h:
4412 silc_client_del_client and silc_client_del_client_by_id.
4413 Affected file lib/silcclient/idlist.c.
4415 * Moved the clientincludes.h from includes/ to silc/ and
4416 serverincludes.h from includes/ to silcd/.
4418 * The modes for the CMODE and CUMODE are now passed as
4419 uint32 for application with COMMAND_REPLY. The affected
4420 file is lib/silcclient/command_reply.c.
4422 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4424 * /WHOIS without arguments shows client's own information.
4425 Affected file lib/silcclient/command.c.
4427 * Changed PING to not accept any arguments. The specs
4428 says that client can ping only the connected server so
4429 requiring an argument is not needed. Affected file is
4430 lib/silcclient/command.c.
4432 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4434 * Fixed a fatal bug in private message sending and reception
4435 encryption and decryption when using private message keys.
4436 The implementation was incorrect and did not follow the
4437 specification. It causd that some of the message were
4438 lost since it did not use the sending and receiving keys
4439 as the protocol suggests. This has been fixed and will cause
4440 incompatibilities with older clients when sending private
4441 message encrypted with private message keys. Affected files
4442 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4443 and various other in Irssi SILC Client.
4445 Added `responder' boolean argument to the functions
4446 silc_client_add_private_message_key[_ske] to indicate when
4447 the key is added as responder or initiator of the key
4450 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4452 * Removed the silc_ske_check_version function and created
4453 a SilcSKECheckVersion callback. Added also a function
4454 silc_ske_set_callbacks that is now used to set all SKE
4455 callbacks. The callback functions are not given to
4456 the SKE functions anymore, but this function is used to
4459 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4461 * Added `silc_version' argument to the silc_client_alloc
4462 to define the version of the application for the library.
4463 The library will use the version string to compare it
4464 against the remote host's (usually a server) version
4465 string. Affected file lib/silcclient/silcapi.h
4467 * Added the KE protocol context to Key Agreement context
4468 in client library so that we can abort the SKE if it
4469 is in process when we get timeout. Affected file is
4470 lib/silcclient/client_keyagr.c.
4472 * Do not resolve the client ID forever if it returns in the
4473 first time that such client does not exist. This was done
4474 for example with private message. Affected file is
4475 lib/silcclient/client_prvmsg.c.
4477 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Do not add regex.h for WIN32. The affected file
4480 includes/silcincludes.h.
4482 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4483 not work yet 100%. It generates the DLL's automatically
4484 when compiling with --with-win32 under cygwin.
4486 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4488 * lib/contrib/regex.c is not compiled on WIN32.
4490 * Added silc_net_get_socket_opt function to the
4491 lib/silcutil/silcnet.h.
4493 * Added includes/silcwin32.h for WIN32 specific includes
4496 * Do not use ptime structure or any of the posix process
4497 functions on WIN32 in lib/silccrypt/silrng.c.
4499 * Added silc_gettimeofday to provide generic function
4500 for struct timeval on all platforms. Added the function
4501 to lib/silcutil/silcutil.h.
4503 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4505 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4506 library as they clearly belong there. As a plus side we
4507 can make the actual socket connection routines platform
4510 Added also new generic function silc_socket_read and
4511 silc_socket_write (that used to be silc_packet_[read/write].
4512 The implementation of these are platform specific.
4514 * Added WIN32 specific routines of silc_socket_[read/write]
4515 to lib/silcutil/win32/silcwin32sockconn.c.
4517 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4519 * Added preliminary support for native WIN32 compilation under
4520 cygwin (using the -mno-cygwin option for GCC) to the
4521 ./configure.in.pre. The --with-win32 now prepares the
4522 compilation for native WIN32.
4524 * Rewrote the SILC Scheduler interface in the file
4525 lib/silcutil/silcschedule.h. The scheduler is now context
4526 based and does not have anymore any global static scheduler.
4527 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4528 and created lib/silcutil/win32 directory for WIN32 based
4531 * Added Unix specific network routines to the
4532 lib/silcutil/unix/silcunixnet.c and the old
4533 lib/silcutil/silcnet.c includes now only generic routines.
4535 Added WIN32 specific network routines to the
4536 lib/silcutil/win32/silcwin32net.c.
4538 * Added Unix specific utility functions from the
4539 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4541 * Added WIN32 SILC Scheduler to the file
4542 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4545 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4547 * Do not handle JOIN notify in the server if the target client
4548 is not registered (idata->registered == FALSE). The affected
4549 file is silcd/packet_receive.c.
4551 * Update the nickrec->founder in event_cumode in the Irssi SILC
4552 client. Affected file irssi/src/silc/core/silc-channels.c.
4554 * Fixed the CUMODE_CHANGE notify handling in the server when
4555 server and router are announcing their clients on channels.
4556 Now the mode changes are saved and notified correctly. The
4557 affected file is /silcd/packet_receive.c.
4559 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4560 They really did not replace the cache entry in the ID Cache.
4561 Now they do that. Affected file silcd/idlist.c.
4563 * Fixed the KICK notify handling in the Irssi SILC client to
4564 update the channel records so that the kicked client does not
4565 appear to be on the channel. The affected file is
4566 irssi/src/silc/core/silc-channels.c.
4568 * Always update the conn->current_channel when executing command
4569 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4571 * Fixed the KILL notify handling in Irssi SILC client to remove
4572 the killed client on all channels.
4574 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Fixed the silc_parse_command_line to remove extra spaces
4577 from the start and end of the arguments. Affected file is
4578 lib/silcutil/silcutil.c.
4580 * Cancel and free any active protocol in the function
4581 silc_server_close_connection. Affected file silcd/server.c.
4583 * Cancel and free any active protocol in the function
4584 silc_client_close_connction. Affected file is
4585 lib/silcclient/client.c.
4587 * Do not execute the KILL command for clients that are in
4588 history (ie. they are not in the network). Affected file is
4591 * Fixed KILL notify handling, client does not crash anymore.
4592 Affected file irssi/src/silc/core/silc-channels.c.
4594 * Reduced the default packet buffer size from 2048 to 1024 in
4595 lib/silccore/silcpacket.c.
4597 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4598 counter to the SKE context that is incresed when the SKE library
4599 performs async operation outside the library. If the outside
4600 process frees the SKE context and FREED status will be set
4601 and the library will detect after the sync operation that the
4602 libary is freed. The affected files are
4603 lib/silcske/silcske[_status].[ch].
4605 * Resolve the client entry information in the function
4606 silc_client_channel_message to assure that NULL pointer is not
4607 passed as client entry to the application. */
4609 * Fixed the task timeout calculation to assure that there is
4610 never negative timeouts. The affected file is
4611 lib/silcutil/silcschedule.c.
4613 * Fixed the channel user mode notification sending in server.
4614 It was sent point-to-point to the router (or to server by router)
4615 but it needs to be destined to a channel. The routines now
4616 supports sending the channel user mode notifys to the channels
4617 when announcing clients and channels. Affected files are
4618 silcd/server.c and silcd/packet_receive.c.
4620 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4621 It did not actually replace the old channel entry in the cache.
4622 Affected file lib/silcclient/client_notify.c.
4624 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Fixed a possible crash in silc_packet_send_prepare. It now
4627 assures always that there is enough space in the buffer and
4628 at the tail area of the buffer (for MAC).
4630 Fixed the inbound buffer reallocation in silc_packet_read.
4631 It was old code and did not handle the reallocation correctly.
4634 The affected file is lib/silccore/silcpacket.c.
4636 * Fixed buffer overflow in silc_parse_nickname in the file
4637 lib/silcutil/silcutil.c.
4639 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * make install generates new server keys only if there is not
4644 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4647 Added check that if the NOREPLY is set then we will not send
4648 the away message. This avoids infinite loop of away messages
4649 if both clients are away. The affected file is
4650 lib/silcclient/client_prvmsg.c.
4652 * Fixed client crash if /NICK was given without arguments.
4653 Affected file lib/silcclient/command.c.
4655 * Server does not send the invite list in INVITE command back
4656 to the client if the list was not altered. Added this notion
4657 to the protocol spec as well. Affected file silcd/command.c.
4659 Fixed possible crash in INVITE command by checking the
4660 value of silc_server_get_client_route command.
4662 * Fixed the INVITE notify type handling. The arguments are now
4663 taken in correct order and client does not crash. The affected
4664 file is irssi/src/silc/core/silc-channels.c.
4666 Removed the "Inviting xxx to channel" message from the
4667 client library away and let the application handle it.
4668 Affected file lib/silcclient/command.c. Added that message
4669 to Irssi SILC client's message formats.
4671 * Fixed CMODE command crash in client. It now checks the
4672 amount of arguments correctly and does not crash. The affected
4673 file is lib/silcclient/command.c.
4675 * Do not create new channel automatically in silc_channels_join
4676 but check whether the channel by that name already exists.
4677 Affected file irssi/silc/core/silc-channels.c.
4679 * Do not send the SERVER_SIGNOFF to router if the disconnected
4680 entity was the router. Affected file silcd/server.c.
4682 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4683 SILC client as it was missing from there.
4685 Added the handling of the KICK notify to the Irssi SILC client
4686 as it was missing. Added "you have been kicked" message to
4687 Irssi SILC client's message modules formats.
4689 Added the handing of the KILL notify to the Irssi SILC client
4690 as it was missing. Added the kill message module formats
4693 The affected file is irssi/src/silc/core/silc-channels.c.
4695 * The router did not save the channel mode the server announced.
4696 Affected file silcd/packet_receive.c.
4698 * Fixed a possible crash in INFO command in server. If the
4699 server did not provide the server info it crashed. Affected
4700 file silcd/command.c.
4702 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Fixed the GETKEY command in the server to check also the
4705 global list. Otherwise the GETKEY would not work correctly
4706 in normal SILC server. Affected file silcd/command.c.
4708 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Fixed GETKEY crash, it crashed if the command did not succseed.
4712 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4715 is now real and not just an macro interface to GMP.
4717 Removed the entire GMP from the source tree and imported new
4718 NSS MPI library instead. Reason for removing GMP is that it is
4719 extremely large and compiles extremely slow. The NSS MPI
4720 is only a few files and compiles in less than 10 seconds.
4721 The speed is also about the same as GMP. The MPI is imported
4722 to lib/silcmath/mpi.
4724 If the system has GMP installed we will still use the GMP.
4725 If it is not then the NSS MPI will be compiled.
4727 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Merged a long nickname (127 characters long) crash bugfix from
4730 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4732 * Merged a freed memory reference bugfix from Irssi CVS tree.
4733 Affected file irssi/src/core/commands.c.
4735 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Added the server's public key sving and verification to the
4738 server when performing the SKE. This was missing and the
4739 remote server's (or router's) public key was accepted without
4740 checking whether we have it previously or trust it at all.
4741 Affected file silcd/protocol.c.
4743 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Check in the silc_server_timeout_remote if protocol is active
4746 and make sure that the protocol's final callback is called so
4747 that all memory if freed. Affected file silcd/server.c.
4749 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * silc_server_whois_send_reply crashed the server if the nickname
4752 was 127 characters long. Affected file silcd/command.c.
4754 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Added sanity check to the silc_server_new_client. If the hostname
4757 is provided inside username then check that the provided hostname
4758 really is the same as the resolved one. If the hostname was not
4759 resolved then check it from the public key. Affected file is
4760 silcd/packet_receive.c.
4762 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4763 if the server disconnected us and the connection is not valid
4764 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4766 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4767 the library to the lib/silcutil/silcutil.[ch].
4769 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Close log file after open. Affected file
4772 lib/silcutil/silclog.c.
4774 * Check whether sock == NULL in silc_client_send_packet and return
4775 if it is. Affected file lib/silcclient/silcclient.c.
4777 * Check rec->entry == NULL in the Irssi SILC Client before
4778 sending the channel message. Affecte file is
4779 irssi/src/silc/core/silc-servers.c.
4781 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4783 * Merged a splitted window bugfix from Irssi CVS tree. The
4784 affected file is irssi/src/fe-text/textbuffer-view.c.
4786 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4787 It did not print nickname.
4789 * Improved the distributions system a bit.
4791 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4794 irssi/src/fe-text/gui-window.c.
4796 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4797 to in-active server. The affected file is
4798 irssi/src/silc/core/client_ops.c.
4800 * Resolve the client in USERS command reply if the entry does
4801 not have username resolved. The affected file is
4802 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4803 command to WHOIS command to really resolve stuff. The USERS
4804 is not used any more in any critical section so WHOIS can
4805 be used even though it might be slower than IDENTIFY.
4807 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4810 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Changed the protocol API a bit more consistent in the
4813 lib/silccore/silcprotocol.[ch].
4815 * Changed the following headers to ROBODoc format:
4817 lib/silccore/silcpayload.h
4818 lib/silccore/silcprotocol.h
4819 lib/silccore/silcsockconn.h
4821 All core library headers are now formatted.
4823 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed a bug in Irssi SILC client; do not show that you are
4826 server/router operator if you really are not. Affected file is
4827 irssi/src/silc/core/client_ops.c.
4829 * Renamed silc_command_free_payload to silc_command_payload_free.
4830 Affected file lib/silccore/silccommand.h
4832 * Added silcmath.h to include the prototoypes of various routines
4833 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4836 * Changed the following headers to ROBODoc format:
4838 lib/silccore/silcchannel.h
4839 lib/silccore/silccommand.h
4840 lib/silccore/silcid.h
4841 lib/silccore/silcidcache.h
4842 lib/silccore/silcmode.h
4843 lib/silccore/silcnotify.h
4844 lib/silccore/silcpacket.h
4845 lib/silcmath/silcmath.h
4847 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added checking to the server code not to start the server if
4850 ciphers and stuff are not configured properly. Affected files
4851 silcd/serverconfig.[h] and silcd/server.c.
4853 * Changed the layout of the header files of the public interfaces
4854 in the SILC libraries. The new layout supports ROBODoc
4855 documentation tool (and some others) so that it is easy to create
4856 a library reference manual. All the other headers and source
4857 code must still follow the CodingStyle document. Also source
4858 code must not include these ROBODoc stuffs, only the headers.
4859 Furthermore, all public interface headers must now be named
4860 by using `silc' prefix, example: silcapi.h, silccipher.h.
4861 Some files were renamed due to this. All the other headers
4862 must not be used as public interfaces. I will update the
4863 CodingStyle document later. Changed following headers, so far:
4865 lib/silcclient/silcapi.h
4866 lib/silccore/silcauth.h
4867 lib/silccore/silcprivate.h
4868 lib/silccrypt/silcdh.h
4870 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Removed silc_client_packet_send_flush from the client library
4875 as it is not needed. Affected file lib/silcclient/client.[ch].
4877 * Added printing of message of unresolved authentication method
4878 to the Irssi SILC client. Added it to the module formats.
4879 Removed the same message from the client library.
4881 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Added new distribution feature, DISTLABEL. Every distribution
4884 can define own preprocessor label that can be used in the
4885 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4886 file distributions, acconfig.h.pre and prepare.
4888 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Added Makefile.defines_int to include the actual definitions
4891 for Makefile.defines.in. Tested the new distribution system,
4892 created distributions and tested installation.
4894 * Added AWAY message printing to the Irssi SILC client. Added
4895 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4897 * Added SCONNECT command to call the SILC's CONNECT command.
4898 Cannot use CONNECT directly since Irssi uses that internally.
4899 Affected file irssi/src/silc/core/silc-servers.c.
4901 Added ACTION local command. It is same as ME command but takes
4902 the channel as mandatory argument.
4904 Rewrote some of the Irssi's help files to suite for SILC
4907 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added Makefile.defines[.in] that should for now on be included
4910 in all Makefile.am file in the source tree. That file includes
4911 all common compilation definitions for SILC source tree.
4913 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Minor changes to the ./prepare script to change the package
4916 name according the distribution name to the configure.in.
4918 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Created new distribution system. Added file `distributions'
4921 that defines all the distributions that can be created out of
4922 the SILC source tree. The ./prepare script now reads that
4923 file to determine how to prepare the distributions. The
4924 first argument to the ./prepare is the name of the distribution
4925 and second is the version of the distribution. If given
4926 without arguments it creates the default (toolkit) distribution
4927 with the default version (defined in ./prepare).
4929 All Makefile.am files that are subject to the distributions
4930 are now named as Makefile.am.pre. These are ./Makefile.am
4931 and lib/Makefile.am. Others may be changed later.
4933 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added invite list, ban list, some key management and connection
4936 error message printing to module formats in the Irssi SILC client.
4938 * Added new silc_client_set_away_message to set the away message
4939 that is back to the person who sent private message. The
4940 affected file lib/silcclient/silcapi.h and the
4941 lib/silcclient/client_prvmsg.c.
4943 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed the private message sending in the Irssi SILC client,
4946 added local command KEY to the Irssi SILC client.
4948 Added key management and key agreement message formats to the
4949 irssi/src/fe-common/silc/module-formats.[ch].
4951 Added USERS (alias WHO) printing, server/router operator
4952 indication and LIST command printing to the module formats.
4954 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Fixed channel joining notify handling, cumode notify handling
4957 from Irssi SILC client.
4959 * Added SILC specific module-formats to the Irssi SILC client so
4960 that SILC specific message hilighting, colors etc is possible.
4961 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4963 Added channel mode, channel user mode, actions, notices,
4964 whois and whowas printing to the the module-formats.c.
4966 * Fixed a bug in channel deletion in the server. The channel
4967 is not left to the cache even if the channel founder auth mode
4968 is set when there are no users anymore on the channel. Affected
4969 file silcd/server.c.
4971 * The silc_net_localhost now resolves the entire hostname including
4972 the domain name. Affected file lib/silcutil/silcnet.c.
4974 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Changed the ask_passphrase client operation to be ascynchronous.
4977 It has now a completion callback and a context that the
4978 application must call after it has got the passphrase from
4979 the user. Affected files lib/silcclient/silcapi.h,
4980 lib/silcclient/protocol.c, lib/silcclient/command.c and
4983 Added SilcAskPassphrase callback that the application calls
4984 to deliver the passphrase to the library.
4986 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4987 The public key verification and especially a certificate
4988 verification is asynchronous procedure.
4990 Added new SILC_SKE_STATUS_PENDING status to indicate the
4991 request is pending and a callback will be called to finalize
4994 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4995 indicate that remote end did not send its public key (or
4996 certificate), even though we require it. Added check for this
4997 condition in the SKE. This was a security bug, now fixed.
4999 Defined new SilcSKEVerifyCbCompletion callback that is called
5000 when the verification process is completed.
5002 The affected files lib/silcske/silcske_status.h and
5003 lib/silcske/silcske.[ch].
5005 * Changed the verify_public_key client operation to be async
5006 as well. Defined SilcVerifyPublicKey callback that is used to
5007 indicate the success of the public key verification process.
5009 Changed the server and client to use the new async client
5012 * Changed the Irssi SILC client's internal scheduler to be called
5013 twice as many times as it used to be. As a result the client
5014 should be a bit faster now. Affected file is
5015 irssi/src/silc/core/silc-core.c.
5017 * Added support to Irssi SILC client of asynchronous public key
5018 verification and passphrase inquiry. Affected file is
5019 irssi/src/silc/core/silc-core.c.
5021 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Do not say "You have left channel %s" in client library.
5024 Moved it to the application. Affected files are
5025 lib/silcclient/command.c and silc/client_ops.c.
5027 * Fixed silc_client_get_clients. Command context was not
5028 duplicated and was freed memory in the callback. Affected
5029 file lib/silcclient/idlist.c.
5031 * Do not say "you are now talking..." on JOIN command in the
5032 client library. The appliation must handle it.
5034 * Do not say ".. changed topic to" in command reply in the
5035 client libary. The application must handle it.
5037 * Fixed TOPIC command sending in the client library.
5039 * Fixed a memory leak in silc_client_command_free in the file
5040 lib/silcclient/command.c.
5042 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Imported a modified version of Irssi client to the source tree.
5045 The Irssi will be used to create a new client called
5046 Irssi SILC. Imported to irssi/.
5048 Added silc_core_init_finish function to the Irssi. Affected
5049 file irssi/configure.in.
5051 A lot changes in the Makefile.ams around the irssi tree.
5053 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Do not rehash if the new size is same as the old size of the
5056 hash table, in the silc_hash_table_rehash*. The affected file
5057 lib/silcutil/silchashtable.c.
5059 * Replaced hash_table_del_by_context calls from the server
5060 (when channel->user_list and client->channels) to the
5061 hash_table_del as it is sufficient and faster.
5063 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Added silc_hash_table_list, silc_hash_table_get and the
5066 SilcHashTableList structure to provide an alternative way to
5067 traverse the hash table. The affected files are
5068 lib/silcutil/silchashtable.[ch].
5070 * Changed the server's idlist routines to use the hash table
5071 routines to optimize the code.
5073 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Replaced the client entry's `channel' list and channel entry's
5076 `user_list' list to hash tables for optimized lookup. Changed
5077 the code to use the hash table interface around the code.
5078 Affected file lib/silcd/idlist.[ch].
5080 * Added `auto_rehash' boolean argument to the function
5081 silc_hash_table_alloc to indicate whether the hash table should
5082 auto-rehash when it thinks is appropriate time. It will
5083 increase the hash table size if the there is twice as much
5084 entries in the table than the size of the table, and will
5085 decrease the size if there are twice as less entries than
5086 the size of the table.
5088 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5092 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * silc_idcache_purge_by_context deletes the entry now by context
5095 as it is supposed to do. Affected file lib/silccore/idcache.c.
5097 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5098 client is not anymore valid (WHOWAS givens the info) and not
5099 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5101 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Removed the `data' and `data_len' arguments from the ID Cache
5104 interfaces and added `name' argument. ID Cache does not handle
5105 anymore the binary data only a names associated with given ID.
5107 * When hashing a Client ID with silc_hash_id the entire ID is
5108 not hashed anymore, instead only the hash of the Client ID is
5109 hashed. This way we can access the Client ID from the cache
5110 with Client ID but with the hash of the ID (which is a hash of
5111 the nickname) as well without any difference in performance.
5113 Added also silc_idcache_find_by_id_one_ext to do one on one
5114 searching when we have the actual ID. Added also function
5115 silc_hash_client_id_compare. The affected files are
5116 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5118 * When hashing the name associated with a ID it is always done
5119 in lowercase. This way we can access the cache without worrying
5120 about case-sensitivity, even though, for example nicknames are
5123 * Fixed a bug in server with channel message sending. It put
5124 wrong ID type as destination ID. The affected file
5125 silcd/packet_send.c.
5127 * silc_idcache_del_by_context now deletes from all hash tables
5128 by context. Affected file lib/silccore/idcache.c.
5130 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Changed the client library to use the new ID Cache interface.
5133 Changes around the source tree.
5135 * Added silc_hash_table_rehash_ext to rehash with specific
5136 hash function. Affected file lib/silcutil/silchashtable.[ch].
5138 * Added silc_hash_string_compare to compare two strings in the
5139 hash table. Affected file lib/silcutil/silcutil.[ch].
5141 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Added new function silc_idcache_del_by_context into the
5144 lib/silccore/idcache.[ch].
5146 * Changed the server's ID list routines to use the new ID Cache
5147 interface. Changes around the source tree.
5149 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Added silc_hash_table_del[_by_context]_ext functions in to the
5152 lib/silcutil/silchashtable.[ch].
5154 Removed silc_hash_table_find_all* routines and added new
5155 silc_hash_table_find_foreach to replace them.
5157 Added silc_hash_table_replace_ext function as extended
5158 replacing function. Separated the simple hash table interface
5159 from the extended hash table interface in the file
5160 lib/silcutil/silchashtable.h.
5162 * Fixed minor bugs and changed it to use some of the new
5163 hash table functions in lib/silccore/idcache.c
5165 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Added new function silc_hash_table_find_all to return all keys
5168 in the hash table by the specified key. As the hash table is
5169 collision resistant it also makes it possible to have several
5170 duplicate keys in the hash table. This function may be used to
5171 find all of the keys from the hash.
5173 Added user_context arguments to the SilcHashFunction,
5174 SilcHashCompare and SilcHashDestructor to deliver user specified
5177 Added new fuctions silc_hash_table_find[_all]_ext to do
5178 extended lookup with specified hash and compare functions and
5179 specified user contexts.
5181 Added new function silc_hash_table_add_ext to add the key
5182 with specified hash function and user context.
5184 Added new function silc_hash_table_foreach to traverse all
5185 entrys in the hash table. Added SilcHashForeach callback
5188 Added new function silc_hash_table_del_by_context to delete
5189 the entry only if the context associated with the key matches.
5191 Affected files are lib/silcutil/silchashtable.[ch].
5193 * Removed silc_hash_[server/client/channel]_id and added just
5194 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5195 silc_hash_id_compare to compare two ID's using as the hash table
5196 comparison function. Added also silc_hash_data to hash
5197 binary data and silc_hash_data_compare to compare it.
5199 * Removed silc_idlist_find_client_by_hash as it is not needed
5200 anymore. Affected file silcd/idlist.[ch].
5202 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5203 to use internally the SilcHashTable. The new ID Cache is a lot
5204 faster than the old one. Some of the ID Cache interface was also
5205 rewritten and obsolete and stupid functions were removed.
5207 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added entry_count field to the SilcHashTable to keep the number
5210 of the entries in the table. Implemented the function
5211 silc_hash_table_rehash. Added new function
5212 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5214 Fixed a minor bug in silc_hash_table_free.
5216 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5217 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5218 into the lib/silcutil/silcutil.[ch].
5220 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5222 * Implemented a collision resistant hash table into the
5223 lib/silcutil/silchashtable[ch]. See the header and the source
5224 for the SilcHashTable API.
5226 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Merged dotconf version 1.0.2 into lib/dotconf.
5230 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Do not compile anything in lib/silcsim/* if the SIM support
5233 is not enabled. The tree should now compile without problems
5236 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Compiled the SILC under cygwin. Compiled and tested briefly
5239 without problems. More tests needed. The SIMs didn't compile
5242 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5244 * Fixed possible crash in silc_get_username in the
5245 lib/silcutil/silcutil.c.
5247 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Fixed a va_arg in silc/client_ops.c.
5251 * Oops, RC5 routines were named AES and caused some problems
5252 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5254 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added new SilcIDIP structure into the lib/silccore/id.h and
5257 replaced the old `ip' fields from all SILC ID's to that type.
5258 This is a step towards IPv6 support.
5260 The silc_id_get_len takes now the ID as an extra argument.
5261 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5262 both IPv4 and IPv6 based ID's.
5264 The affected files are lib/silccore/id.[ch] and other files
5265 around the tree using these routines.
5267 * Removed the ID length arguments in server from various
5268 silc_server_send_notify_* routines -> they are not needed
5271 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Fixed memory leak in silc_encode_pem_file in the file
5274 lib/silcutil/silcutil.c.
5276 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Check minor version as well in the SKE. Affected files are
5279 silcd/protocol.c and lib/silcclient/protocol.c.
5281 * Added --identifier option to the server so that an identifier
5282 can be when creating the public key for the server. Affected
5283 file is silcd/silcd.c.
5285 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5286 lib/silccrypt/silcpkcs.c.
5288 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Register default ciphers and stuff when using -C option with
5291 the server. Affected file sildc/silcd.c.
5293 * Put back the servers public key filename format, it is better
5294 than the new one. For now, the client keys are saved with the
5295 new filename format. The affected file silc/client_ops.c.
5297 * Implemented the Cipher API for the rest of the ciphers that
5298 did not implement it or implemented it the wrong way.
5300 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Register default ciphers and stuff when using the -S option
5303 in the client. Affected file silc/silc.c. Same also when
5304 creating new key pair with -C option.
5306 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Fixed the silc_verify_public_key client operation function to
5309 save the public keys differently. The fingerprint is now
5310 used as filename and not the hostname. This way also the
5311 client keys are saved uniquely and not with hostnames. The
5312 affected file is silc/client_ops.c.
5314 * Trimmed the silc_hash_fingerprint function to remove extra
5315 whitespaces from the end of the fingerprint. The affected
5316 file is lib/silccrypt/silchash.c.
5320 * Added silc_cipher_register_default function to register all
5321 default ciphers. It can be used when configuration files
5322 does not exist and the application does not want any specific
5323 ciphers in any specific order.
5325 The SilcDList is now used as silc_cipher_list dynamically
5326 allocated cipher list. Removed the static list all together
5327 and now all ciphers must be allocated to the dynamic list.
5328 The silc_cipher_alloc routine was changed to check only the
5331 All silc_cipher_* routines that used to return int returns
5334 The affected files lib/silccrypt/silccrypt.[ch].
5336 * The same thing was done to silc_hash_* as for silc_cipher_*
5337 routines. Affected files lib/silccrypt/silchash.[ch].
5339 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5340 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5341 Added also silc_pkcs_[un]register[_default] functions.
5342 Removed the data_context from the PKCS API.
5344 * Added silc_hmac_register_default function to register default
5345 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5346 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5347 to unregister all hmacs at once.
5349 * Register the default ciphers, hash functions, PKCSs and HMACs
5350 if client's configuration file does not exist. The affected
5353 * The client did not load the hash functions from the SIM
5354 modules at all. Added support for this. Affected file is
5355 silc/clientconfig.c.
5357 * When decoding public key with silc_pkcs_public_key_decode, check
5358 the supported algorithm only if PKCS are registered. Affected
5359 file lib/silccrypt/silcpkcs.c. The same was done with the
5360 silc_pkcs_private_key_decode.
5362 * Fixed the SILC List routines to keep the list always in order.
5363 It used to change the list's order when traversing the list but
5364 not it preserves the order. Affected file lib/trq/silclist.h.
5366 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added the client library to use the SilcSocketConnection's
5369 reference counter (by silc_socket_dup) to prevent the bug that
5370 the socket object may be freed underneath async operation.
5372 * The name resolv library checking fixes in the configure.in.pre.
5375 * Created new version of the protocol drafts for future
5376 development. The -03 drafts are the ones that will be changed
5377 in the trunk now and the -02 will remain as they are.
5379 * Send list of CUMODE notifys to the router when announcing
5380 the channel users to the router. Affected file silcd/server.c.
5381 If the router receiving channel founder CUMODE for a channel
5382 that already has channel founder it will send CUMODE notify
5383 to the sender to remove the channel founder rights from the
5384 announced client. Affected file silcd/packet_receive.c.
5386 * The CUMODE notify may now use Server ID as well as the entity
5387 who changes the mode. Updated protocool specs.
5389 * Updated INSTALL and README files.
5391 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * New web pages in the http://silc.pspt.fi. The pages was
5398 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Implemented the [DenyConnectin] config section in the server.
5401 Added silc_server_config_denied_conn to check whether incoming
5402 connection is denied. Affected file silcd/serverconfig.[ch].
5404 * Do not check the ports when checking the incoming configuration
5405 data if the port is 0, meaning any. Affected file is
5406 silcd/serverconfig.c.
5408 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Fixed buffer overflow in silc_string_compare in the file
5411 lib/silcutil/silcutil.c.
5413 * Fixed double free in silc_server_command_leave in the file
5416 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Fixed the version checking in the server. Affected file is
5421 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Fixed the configuration data fetching when accepting new
5424 connections in the server. Affected file silcd/server.c.
5426 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Added `sender_entry' argument to the function
5429 silc_server_packet_relay_to_channel so that we can check
5430 whether some destination actually belongs to the same route
5431 the sender belongs (ie, we must not resend the packet to the
5432 sender). Affected file silcd/packet_send.[ch].
5434 * Added `servername' field to the SilcClientEntry in the server
5435 to hold the name of the server where client is from. Affected
5436 file is silcd/idlist.h.
5438 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Moved the channel message encrypting in the router betwen
5441 router connections from silc_server_channel_message to the
5442 silc_server_packet_relay_to_channel since we want to check
5443 whether we have anybody channel before encrypting anything.
5444 Affected files silcd/packet_[receive/send].c.
5446 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed the [AdminConnection] server config section to support
5449 multiple entries. Affected file silcd/serverconfig.c.
5451 * Added support into the server to check the validity of the
5452 incoming connection before executing any KE or authentication
5455 * The connection configuration is now saved to the KE and
5456 connection auth protocol contexts and not fetched anymore in
5457 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5459 * The local hosts listenning address and port is also resolved
5460 now when starting the server. We want to have the socket object
5461 to include the real address and port for the listener. Added
5462 new function silc_net_check_local_by_sock into the files
5463 lib/silcutil/silcnet.[ch].
5465 * Fixed a broadcast bug in server -> do not broadcast if we
5468 * Fixed a routing bug. Do not route broadcast packets ever.
5469 Broadcast packets must be processed always and not routed since
5470 they may be destined to some other host than yourself and thus
5471 would get routed without no good reason. Affected file is
5474 * Added function silc_server_config_is_primary_route to check
5475 whether primary router connection has been configured (a router
5476 configuration that we are initiating). If there is not, we
5477 will assume that there is only two routers in the SILC network
5478 and we will use the incoming router connection as our primary
5479 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5481 * Changed the order of the broadcasting. Broadcast _after_ the
5482 packet has been processed not before. Affected file is
5485 * Fixed a [ClientConnection] parsing bug. The port was never
5486 parsed correctly thus resulting to port 0. Affected file
5487 silcd/serverconfig.c.
5489 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5490 argument and did not set the broadcast packet flag. Affected
5491 file silcd/packet_send.c. Fixed same bug in the function
5492 silc_server_send_notify as well.
5494 * If we receive NEW_ID packet for our own ID in the server, ignore
5497 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Removed the nickname from the Private Message Payload.
5502 Updated the code and the protocol specs.
5504 * Updated protocol specs for submitting to the IETF.
5506 * Tweaked the Random Number Generator a bit. Affected file
5507 lib/silccrypt/silcrng.c. Exported a new function
5508 silc_rng_[global]_add_noise which can be used to add more
5511 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Do not parse packets with different timeout when protocol
5514 is active -> may cause problem with rekey. Affected file
5517 * When server receives signoff notify it must not create
5518 new channel key if the client is on any channels since the
5519 sender of the signoff notify will create it.
5521 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added printing of error messages during SKE protocol from the
5524 failure packet sent by server during SKE. Affected file
5527 * Removed the client's failure_callback handling with timeout
5528 and handle it immediately when received.
5530 * The SKE library returned wrong type in SUCCESS and FAILURE
5531 packets. They must be 32 bit MSB not 16 bit MSB.
5533 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Ok, rewrote the logic of the re-key and now it seems to work.
5536 I tested it on high traffic with frequent re-keys without
5537 problems. Added hmac_receive (and renamed hmac to hmac_send)
5538 in SilcClientConnection in lib/silcclient/client.h and
5539 in SilcIDListData in silcd/idlist.h. Also, removed the
5540 SilcPacketParserContext's cipher and hmac fields as they are
5541 not needed anymore and actually caused some problems when
5542 the ciphers and hmac's changed underneath the packet parser.
5544 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * If re-key protocol is active then process the incoming packets
5547 synchronously since we must assure that icoming packets encrypted
5548 with the old key is processed before the new keys is set to
5549 use. This is true other packets than for REKEY packets.
5550 Affected file silcd/server.c. The same was done to client library
5551 as well, affected file lib/silcclient/client.c.
5553 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Fixed bug in client and server to accept the force send if
5556 the packet is send from silc_[server/client]_packet_process
5557 function. Otherwise the packets are never delivered, oops.
5559 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Disable force sending of packets when REKEY protocol is active.
5562 We must assure that no packet is sent directly when rekey is
5563 performed. All packets must be sent through packet queue.
5564 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5565 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5566 function is silc_[server/client]_packet_send_real to check
5569 * Replaced the SIM paths from example config files to
5570 /usr/local/modules. Also, make install creates now
5571 /usr/local/silc/logs directory to hold all the SILC server
5574 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Made the configure.in.pre work on Solaris. Patch by salo.
5578 * Made all ciphers compatible with non-x86 machines. Defined
5579 CBC mode macros into lib/silccrypt/ciphers_def.h.
5581 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Fixed the make install.
5585 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * When MAC computation fails the silc_packet_decrypt returned 0
5588 even though it was supposed to return -1. Fixed this. The
5589 affected file is lib/silccore/silcpacket.c.
5591 * Do not replace the config files in /etc/silc (in make install)
5592 if they already exist. Affected file ./Makefile.am.
5594 * Do not send re-key packets immediately but through packet queue.
5595 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5597 * Changed silc_net_check_host_by_sock to return FALSE if the
5598 IP/DNS could not be resolved. Though, it returns the IP address
5599 now even if it could not resolve it (but returns also FALSE).
5600 Affected file lib/silcutil/silcnet.[ch].
5602 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added silc_pkcs_decode_identifier to decode the public key's
5605 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5606 Added also silc_pkcs_free_identifier. Added also new context
5607 SilcPublicKeyIdentifier.
5609 * Added -S option to the silc client. It is used to dump the
5610 contents of the specified public key file.
5612 * Changed the PKCS api to return the public key length when
5613 setting the public key.
5615 * Fixed a fatal bug in the public and private key file loading.
5616 Affected file lib/silccrypt/silcpkcs.c.
5618 * Execute the packet parsing for client with zero (0) timeout
5619 if the protocol is active. Affected file silcd/server.c.
5621 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Made the key generation options to the silcd program. Added
5624 -C option, equivalent to client's option.
5626 * Added new [ServerKeys] config section to the server. It
5627 configures the server's public and private key.
5629 * Defined generic Public Key Payload into the protocol
5630 specification to send specific type of public keys and
5633 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5634 public key or certificate.
5636 * Implemented the GETKEY command to the server and to the
5637 client library and on user interface.
5639 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Made preliminary `make install' work.

5670 SilcClientConnection structure; not needed. Affected file is
5671 lib/silcclient/client.h.
5675 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Do not ask whether user wants to use the negotiated private key
5678 for private messages, just use it. Affected file is
5679 silc/local_command.c.
5681 * Added `send_enc_key' and `enc_key_len' fields to the
5682 SilcIDListData structure since they are needed in the re-key
5683 phase. Affected file is silcd/idlist.[ch].
5685 * Implemented the simple re-key protocol into the server.

5697 the PFS is to be performed in the re-key. Affected file is
5700 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5703 int64 of at least the xintXX size. If void * is less that 4
5704 bytes uint32 * will be used. Defined bool as boolean.
5706 * Changed _ALL_ unsigned long and unsigned int to uint32,
5707 unsgined short to uint16 in the source tree.
5709 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5710 not handle clients that has entry->data.registered == FALSE.
5711 They are not in the network anymore. Affected file is
5714 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Implemented the sending of the SERVER_SIGNOFF notify in the
5717 server. Affected file is silcd/server.c.
5719 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5720 Added also silc_notify_payload_encode_args into the

5723 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5724 Affected file silcd/packet_receive.c.
5726 * Implemented the SERVER_SIGNOFF notify handling in the client
5727 library. Affected file lib/silcclient/client_notify.c. Also,
5728 implemnted the printing of the SERVER_SIGNOFF info to the
5729 application. Affected file silc/client_ops.c.
5731 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5732 if the deleting was successful. Affected file silcd/idlist.[ch].
5734 * Added support for public key authentication in the connection
5735 authentication protocol in the client library. Affected file
5736 lib/silcclient/protocol.c.
5738 * Changed the server's silc_idlist_get_clients_by_* interface
5739 to support already allocated array so that new entries may be
5740 added to pre-allocated array. Affected file silcd/idlist.[ch].
5741 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5742 and command replies.
5744 * All command reply functions in the server now calls the
5745 pending command callback even if error occured. This way the
5746 error will be delivered to the client as well. Affected files
5747 silcd/command.c and silcd/command_reply.c.
5749 * Fixed INFO command to return local server's info if no server
5750 was provided. Affected file lib/silcclient/command.c.
5752 * Removed RESTART command for good. Updated the code and the
5755 * Rewrote parts of the task system. It is a bit simpler now.
5756 Removed unsued task priorities. The affected files are
5757 lib/silcutil/silctask.[ch].
5759 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Moved the USERS printing from the library to the application.
5762 Affected files lib/silcclient/command.c and silc/client_ops.c.
5764 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Added channel key re-key support. The re-key is perfomed
5769 only by the router and is done once in an hour. Added `rekey'
5770 field to the SilcChannelEntry in the server. Affected files
5771 silcd/server.c and silcd/idlist.h.
5773 * Added silc_task_unregister_by_context into the file
5774 lib/silcutil/silctask.[ch].
5776 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added SILC_UMODE_GONE mode to indicate when the client is not
5779 present in the SILC network. Added also support to the local
5780 command AWAY that will set this mode. Added support of showing
5781 "xxx is gone" in WHOIS command. The USERS command shows the
5782 gone status as well.
5784 * Fixed setting server and router operator privileges in the
5785 server's UMODE command. Affected file silcd/command.c.
5787 * Merged the SKE KE1 and KE2 payloads into one payload. The
5788 new KE payload is equivalent to the old KE2 payload.
5790 Cleaned up the SKE Start Payload parsing. It now uses the
5791 simple buffer unformatting to do the parsing. A lot faster
5794 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5795 to the SKE that is used to indicate whether both of the SKE
5796 parties should perform authentication. By default only the
5797 responder performs authentication. By setting this flag also
5798 the initiator must do authentication. By default it is unset
5799 since in normal SKE case, client to server connection, only
5800 the responder should do authentication. When doing SKE between
5801 two clients both should perform authentication. Updated the
5802 code and the protocol specs.
5804 * A little fix to IDENTIFY command in the server. Search the
5805 client first by hash not nickname. Affected file is
5808 * Fixed the silc_client_close_connection to support closing
5809 the client to client connections wihtout deleting too much
5810 data. Affected file lib/silcclient/client.c.
5812 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5813 are received if protocol used to be active but is not anymore
5814 the application would crash due to NULL pointer dereference.
5815 Affected files silcd/server.c and lib/silcclient/client.c.
5817 * Added `hash' field to the SilcClientConnection to include
5818 the hash function negotiated in the SKE protocol.
5820 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5821 to set the channel founder authentication data. A client can
5822 claim the founder rights later by providing the authentication
5823 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5824 This way the channel founder can regain the channel founder
5825 privileges even it is left the channel. This works only on
5826 local server and the client must be connected to the same
5827 server to be able to regain the founder rights. Updated the
5828 protocol specs accordingly.
5830 Added support to the CMODE command in the client to set the
5831 founder auth data. Read the README to see how to set it.
5833 Added support to the CUMODE command to claim the founder
5834 rights. Read the README to see how to do it.
5836 Added support for the founder authentication to the Channel
5837 Entry in the server. Affected file silcd/idlist.h.
5839 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5840 server's CMODE command. Affected file silcd/command.c.
5842 * Added the following new functions into lib/silccore/silcauth.[ch]:
5843 silc_auth_get_method and silc_auth_get_data.
5845 * The server now saves the remote hosts public key to the
5846 SilcIDListData pointer. Affected file silcd/protocol.c.
5848 * The normal server now does not remove the channel entry from
5849 the cache if the founder authentication data is set. It used
5850 to remove it if the founder was the last one on the channel on
5851 the server and left the channel. The auth data is saved and
5852 if the channel is re-joined later the old entry is used with
5853 the old auth data. Affected files silcd/command_reply.c and
5856 * Removed the `pkcs' field from the SilcIDListData structure
5857 in the server; it is not used. Affected file silcd/idlist.h.
5859 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Fixed packet processing on slow links. Partial packets were
5862 never re-processed because the incoming data buffer was cleared
5863 by the application. Application must not directly clear the
5864 sock->inbuf, the packet processing routines handle it. Fixed
5865 this in client library and in server.
5867 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Fixed the WHOIS and IDENTIFY send reply function to really
5870 check whether to send list or just one entry. Affected file
5873 * Cleaned up the LEAVE command's channel key distribution. The
5874 affected file silcd/command.c.
5876 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5877 can enforce the channel mode as well. In that case the ID
5878 includes the ID of the server. The code now enforces the
5879 mode change if the router have different mode than the server.
5881 * The notify client operation with CMODE_CHANGE notify can now
5882 return NULL client_entry pointer if the CMODE was not changed
5883 by client. Application must check for this.
5885 * Added <Server ID> argument to INFO command to support server
5886 info fetching by Server ID.
5888 * Added silc_server_announce_get_channel_users to get assembled
5889 packets of channel users of the specified channel. Affected
5890 file silcd/server.[ch].
5892 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5893 was freed underneath the ID Cache.
5895 * Re-announce clients when the server received CHANNEL_CHANGE
5896 notify from the router. Affected file silcd/packet_send.c.
5898 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5901 crashed since it did not handle the fact that there is no cipher
5902 called "3" and didn't check the error condition. Now fixed.
5904 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5905 flag. It can be used to send message requests.
5907 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Implemented the RESTART command in the client.
5911 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5912 notice type messages. Added notice printing to the user
5915 * The channel keys are not re-generated if the channel's mode
5916 is PRIVKEY, ie private key on the channel exists. Affected
5917 files silcd/server.c and silcd/command.c.
5919 * Fixed a little bug in channel message delivery when channel
5920 private keys are set in the server. Affected file is
5921 silcd/packet_send.c.
5923 * Changed the setting on channel->on_channel = TRUE from the
5924 silc_client_save_channel_key to the JOIN command reply. The
5925 key payload is not received if the private channel key is set.
5926 Affected file lib/silcclient/command_reply.c and the
5927 lib/silcclient/client_channel.c.
5929 * When the CMODE_CHANGE notify is sent and the channel private
5930 key mode is removed the channel key must be re-generated in
5931 other cells as well. Added this support for the router in the
5932 silcd/packet_receive.c.
5934 * Added new local command NOTICE to send notice message on
5935 channel. Affected file silc/local_command.[ch].
5937 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added new local command ME to the client. It is used to send
5940 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5941 some action. Affected file silc/local_command.[ch].
5943 * Changed channel_message and private_message client operations
5944 to deliver the message flags to the application. Added also
5945 the `flags' arguments to the silc_client_send_channel_message
5946 and silc_client_send_private_message functions. Affected file
5949 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Redefined the Private Message Payload to support private message
5952 keys and to support the new private message flags. Updated
5953 the protocol specs. Flags makes it possible to have for example
5954 CTCP style messages.
5956 * Added new type SilcPrivateMessagePayload and defined an API
5957 for it in the lib/silcclient/silcprivate.[ch].
5959 * Tested private message private keys successfully. Tested the
5960 private message key set, unset and list commands with the new
5963 * Redefined the Channel Message Payload to include the channel
5964 message flags (equal with private message flags) to support
5965 for example CTCP style messages.
5967 * Defined some of the message (for channel and private message)
5968 flags. Updated the protocol specs and added the flags to the
5969 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5971 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added SilcKeyAgreementStatus type to the key agreement routines
5974 to indicate the current status and error if one occured.
5975 The status types are defined in the lib/silcclient/silcapi.h.
5977 * Added new local command KEY that is used to set and unset private
5978 keys for channels, set and unset private keys for private messages
5979 with remote clients and to send key agreement requests and
5980 negotiate the key agreement protocol with remote client. The
5981 key agreement is supported only to negotiate private message keys,
5982 it currently cannot be used to negotiate private keys for channels,
5983 as it is not convenient for that purpose.
5985 * Fixed a minor pending callback setting bug in the function
5986 silc_client_get_client_by_id_resolve, now the function works.
5987 Affected file lib/silcclient/idlist.c.
5989 * Added function silc_net_get_local_port to get local bound
5990 port by socket. Added to lib/silcutil/silcnet.[ch].
5992 * Added `sockets' and `sockets_count' fields to the SilcClient
5993 object. They hold the sockets of the listenning sockets in
5994 the client. Listenning sockets may be for example the key
5995 agreement server. Affected file lib/silcclient/client.[ch].
5996 Added functions the silc_client_add_socket and the
5997 silc_client_del_socket. They are exported to the application
6000 * Added ~./silc/clientkeys to support other client's public keys.
6002 * Renamed verify_server_key client operation to verify_public_key
6003 and added one argument to indicate the type of the connection
6004 (server, client etc.).
6006 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added silc_server_connection_auth_request to handle the
6009 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6010 silcd/packet_receive.[ch].
6012 * Added silc_server_send_connection_auth_request into the
6013 silcd/packet_send.c to send the connection auth request packet.
6015 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6018 * Fixed the public key authentication in responder side in the
6019 server. The `auth_data' pointer includes the SilcPublicKey
6020 not the path to the public key. Affected file silcd/protocol.c.
6022 * Implemented the public key authentication in the initiator side
6023 in the server. Affected file silcd/protocol.c.
6025 * Removed the [RedirectClient] config section from the server
6026 configuration. Is not needed and I don't want to implement it.
6028 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Cleaned up the CMODE command in the server. It now works
6031 correctly and supports all the modes defined in the protocol.
6032 Affected file is silcd/command.c.
6034 * Added `hmac_name' field to the SilcChannelEntry in the server
6035 to hold the default HMAC of the channel. It can be set when
6036 creating the channel (with JOIN command). Affected files
6039 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6040 type to indicate the change of the current cipher and hmac
6041 on the channel. Client can safely ignore the <cipher> argument
6042 (if it chooses to do so) since the CHANNEL_KEY packet will
6043 force the channel key change anyway. The <hmac> argument is
6044 important since the client is responsible of setting the new
6045 HMAC and the hmac key into use.
6047 * Fixed the CMODE command in the client library as well.
6049 * Tested CMODE command in router environment successfully.
6051 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Show the version of the remote client (or server) when connecting
6054 to the server. It is logged to the log file. Affected file
6055 is silcd/protocol.c.
6057 * Fixed the KILLED notify handling in the client library. The
6058 client must be removed from all channels when receiving the
6061 Also, do not remove the client entry when giving the KILL
6062 command but when the KILLED notify is received.
6064 * Removed silc_idlist_find_client_by_nickname from the server.
6065 Not needed anymore. Affected files silcd/idlist.[ch].
6067 * Implemented the CHANNEL_CHANGE notify type handling to the
6068 server. Affected file silcd/server.c.
6072 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Added silc_server_send_notify_invite to send the INVITE
6075 notify between routers.
6077 * Implemented the INVITE command correctly to the server.

6086 * Added function silc_server_get_client_resolve to find the
6087 client entry by ID from all ID lists and then resolve it
6088 (using WHOIS) if it cannot be found. Affected file is
6091 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Implemented the BAN command to the client library.
6095 * The JOIN command in the server now checks the invite list
6098 * Changed the silc_command_reply_payload_encode_va and the
6099 silc_command_payload_encode_va to support that if argument is
6100 NULL it ignores and checks the next argument. Affected file
6101 lib/silccore/silccommand.c.
6103 * Added silc_server_send_notify_ban to send the BAN notify
6104 type between routers.
6106 * Chaned the silc_notify_payload_encode to support that if
6107 argument is NULL it ignores and checks the next argument.
6108 Affected file lib/silccore/silcnotify.c.
6110 * Tested ban lists in router environment successfully.
6112 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Implemented BAN command to the server, in silcd/command.[ch].
6116 * Removed the BAN and INVITE_LIST modes from the CMODE command
6119 * Added function silc_string_match to regex match two strings.
6120 Affected files lib/silcutil/silcutil.[ch].
6122 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Redefined parts of the SilcChannelEntry in the server to support
6125 the new ban and invite lists.
6127 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Redefined the INVITE command. The same command can be used to
6130 invite individuals to the channel but also to manage the invite
6131 list of the channel (to add to and remove from the invite list).
6132 Updated the protocol specs.
6134 * Added new command SILC_COMMAND_BAN that can be used to manage
6135 the ban list of the channel. Updated the protocol specs.
6137 * Removed the channel modes: the SILC_CMODE_BAN and the
6138 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6139 in the CMODE command. The equivalent features are now available
6140 using INVITE and BAN commands. Updated the protocol specs.
6142 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6143 in the network about change in the current ban list. The notify
6144 type is not used by the client.
6146 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6147 support the invite lists.
6149 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Added new function silc_string_regexify that converts string
6152 including wildcard characters into regex string that can
6153 be used by the GNU regex library. Added into the file
6154 lib/silcutil/silcutil.[ch].
6156 Added silc_string_regex_combine to combine to regex strings
6157 into one so that they can be used as one regex string by
6158 the GNU regex library. Added into the file
6159 lib/silcutil/silcutil.[ch].
6161 Added silc_string_regex_match to match two strings. It returns
6162 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6164 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Imported GNU regex to the soruce tree into lib/contrib.
6167 Fixed some compiler warning from the regex.c.
6169 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Fixed MOTD command in the server to work in router environment.
6173 * Fixed the MOTD command in the client library to support
6174 the server argument in the command.
6176 * Added `nickname_len' argument to the silc_idlist_add_client
6177 in the server, as the `nickname' argument may be binary data
6180 * Added silc_idlist_get_channels to return all channels from
6183 * Implemented LIST command to the server. Affected file is
6186 * Implemented the LIST command to the client library and on the
6189 * Added [<user count>] argument to the LIST command reply.
6190 With private channels the user count is not shown.
6192 * Updated TODO and README.
6194 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * The client entry's data.registered must be TRUE even with
6197 global client entry on global client list. The data.registered
6198 is used to check whether the client is anymore in the network,
6199 for example with WHOWAS command so it must be valid.
6201 * Fixed the WHOWAS command in the server. It now actually works
6202 in router environment. Added function into silcd/command_reply.c
6203 silc_server_command_reply_whowas_save.
6205 * Added silc_idlist_purge function to the silcd/idlist.c
6206 to periodically purge the ID Cache.

6216 they were buggy because of the WHOWAS information.
6218 * Fixed local command MSG to handle the async resolving of
6219 the remote client properly. It used to fail the first MSG.
6220 Affected file silc/local_command.c.
6222 * Added `data_len' field to SilcIDCache context.
6224 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Update TODO. Todo in commands in the server.
6228 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6231 used by routers as broadcast packet to inform other routers
6232 about the changed user mode.
6234 Implemented the notify handling in the server. Affected file is
6235 silcd/packet_receive.c. Added the function
6236 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6238 * Added new generic Channel Payload and deprecated the New Channel
6239 Payload. The New Channel Payload is now the generic Channel
6242 * Added new argument `mode' to the silc_server_send_new_channel
6243 as it is required in the Channel Payload now.
6245 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6246 and created a new and real SilChannelPayload to represent the
6247 new generic Channel Payload. Implemented the encode/decode
6248 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6250 * Added silc_server_get_client_channel_list to return the list
6251 of channels the client has joined for WHOIS command reply.
6252 Affected file silcd/server.[ch].
6254 * Implemented the channel list sending in the WHOIS command reply
6255 in server and in the client.
6257 Implemented the channel list displaying on the user interface
6258 as well. Affected file silc/client_ops.c.
6260 * Added silc_channel_payload_parse_list to parse list of Channel
6261 Payloads. It returns SilcDList list of SilcChannelPayloads.
6262 Client for example can use this function to parse the list of
6263 channels it receives in the WHOIS command reply. The caller
6264 must free the list by calling silc_channel_payload_list_free.
6265 Affected files lib/silccore/silcchannel.[ch].
6267 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Added one new argument <user mode> to the WHOIS command reply
6270 to return the mode of the user in SILC. Updated the protocol

6280 * Implemented the UMODE command and user modes in general to the
6281 client library and to the user interface.
6283 * Implemented the UMODE command to the server.
6285 * The server now sends UNKNOWN_COMMAND error status if client sends
6286 unknown command. Affected file silcd/command.c.
6288 * All server commands now handle the command identifier the right
6289 way when sending the command reply to the client. The client can
6290 use to identify the command replies with the identifier.
6292 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Added silc_server_get_client_route to resolve the route to
6295 the client indicated by the client ID. Affected file is
6298 * Added silc_server_relay_packet as general function to relay
6299 packet to arbitrary destination. This deprecates functions
6300 like _send_private_message_key, _relay_notify etc. Affected
6301 file is silcd/packet_send.[ch].
6303 Removed silc_server_send_key_agreement,
6304 silc_server_send_private_message_key and
6305 silc_server_packet_relay_notify functions from the file
6306 silcd/packet_send.[ch].
6310 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6311 server. Affected file silcd/packet_receive.[ch].
6313 * Implemented the KILL command to the client. Implemented the
6314 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6315 Affected files lib/silcclient/command[_reply].c and
6316 lib/silcclient/client_notify.c. Implemented the KILL notify
6317 printing in the user inteface.
6319 * Fixed a lot silc_parse_nick memory leaks from the client
6320 library in the file lib/silcclient/command.c.
6322 * Changed the silc_server_send_notify_on_channels's `sender'
6323 argument from SilcSocketConnection to SilcClientEntry to
6324 check the sender as entry and not as connection object and not
6325 to send to the client provided as argument. The affected file
6326 is silcd/packet_send.[ch].
6328 * The notify packets that are destined directly to the client used
6329 to not to be processed by the server. Now changed that and the
6330 server processes all notify packets. After relaying the packet
6331 to the client the notify packet is processed in the server.
6333 * The silc_server_free_client_data now checks whether there is
6334 pending outgoing traffic for the client and purges the data to
6335 the network before removing the client entry.
6337 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6340 an client is killed from the SILC Network. Updated the protocol
6343 Added new function silc_server_send_notify_killed to the
6344 silcd/packet_send.[ch].
6346 * Added function silc_server_packet_relay_notify to relay notify
6347 packets that are destined directly to a client. In this case
6348 the server does not process the notify packets but merely relays
6349 it to the client. Affected file silcd/packet_send.[ch].
6351 Added also silc_server_packet_process_relay_notify to check
6352 whereto relay the notify. Affected file is
6353 silcd/packet_receive.[ch].
6355 * Implemented the KILL command to the server.
6359 * Added the backup schema desgined last fall to the protocol
6360 specs for everyone to see. The specification is in the
6361 *-spec-xx.txt draft and the packet type definitions for the
6362 backup routers is in *-pp-xx.txt draft. Thusly, added also
6363 new packet type SILC_PACKET_CELL_ROUTERS.
6365 * A big security problem in the implementation discovered. The
6366 signoff of an client did not cause new channel key generation
6367 which it of course should've done. The channel keys must be
6368 always re-generated when client leaves (or signoffs) the channel.
6369 The silc_server_remove_from_channels funtion now handles
6370 the channel key re-generation.
6372 * Added `sender' argument to the silc_server_send_notify_on_channels
6373 to not to send the client provided as argument. Affected file
6374 silcd/packet_send.[ch].
6376 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * Implemented OPER and SILCOPER commands into the server and
6381 * Added silc_auth_verify and silc_auth_verify_data to verify
6382 the authentication directly from the authentication payload.
6383 It supports verifying both passphrase and public key based
6384 authentication. Affected file lib/silccore/silcauth.[ch].
6386 * Added `hash' field to the SilcIDListData structure. It is the
6387 hash negotiated in the SKE protocol. Affected file is
6390 * Slight redesigning of the SilcAuthPayload handling routines.
6391 Do not send SilcPKCS but SilcPublicKey as argument.
6393 * Implemented the public key authentication support to the
6394 serverconfig. The public key is loaded from the provided path
6395 and saved as authentication data to void * pointer. Thus,
6396 changed the unsigned char *auth_data to void *auth_data;
6398 * Fixed SHUTDOWN command to send the reply before the server
6399 is shutdown. :) Affected file silcd/command.c.
6401 * Fixed fatal bug in CONNECT command. The hostname was invalid
6402 memory and server crashed. Affected file silcd/command.c.
6404 * Fixed fatal bug in CLOSE command. The server_entry became
6405 invalid but was referenced later in the command. Affected file
6408 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Fixed fatal bug in failure packet handling. Server ignored
6411 the failure and thus crashed when it came.
6415 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6418 that the command may be executed only once in (about) 2 seconds.
6419 The old SILC_CF_LAG flag is same but allows command bursts up
6420 to five before limiting.
6422 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6423 server code. Various commands now includes the CF_LAG_STRICT
6424 flag to disallow any kind of miss-use of the command.
6426 * Fixed the silc_buffer_unformat to not to allocate any data
6427 if the length of the data is zero. It used to allocate the
6428 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6430 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Changed the format of AdminConnection configuration section
6433 in the server. Added username of the admin to the format.
6434 Affected files silcd/serverconfig.[ch].
6436 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6437 to return admin configuration data by host, username and/or
6440 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Implemented WHOWAS command to the server. Added the functions:
6444 silc_server_command_whowas_parse,
6445 silc_server_command_whowas_send_reply,
6446 silc_server_command_whowas_from_client and
6447 silc_server_command_whowas_from_server
6449 * Added <Client ID> argument to the WHOWAS command reply. Updated
6450 the protocol specs accordingly.
6452 * Implemented WHOWAS command and command_reply to the client
6455 Implemented the WHOWAS printing on the user interface.
6457 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Added new argument to the WHOWAS command reply, the real name.
6460 It is an optional argument. Updated the protocol specs.
6462 * Added SilcIDCacheDestructor callback that is registered when
6463 the SilcIDCache is allocated. The callback is called when
6464 an cache entry in the ID Cache expires, or is purged from the
6465 cache. Added into lib/silccore/idcache.[ch].
6467 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6468 to destruct the client entries when the cache entry expires.
6469 Other ID Cache's in server and in the client library ignores
6472 * If the ID Cache entry's `expire' field is zero then the entry
6473 never expires. Added boolean `expire' argument to the
6474 silc_idcache_add function in the lib/silccore/idcache.[ch].
6475 If it is TRUE the default expiry value is used.
6477 * Added silc_server_free_client_data_timeout that is registered
6478 when client disconnects. By default for 5 minutes we preserve
6479 the client entry for history - for WHOWAS command.
6481 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Added support to the server to enforce that commands are not
6484 executed more than once in 2 seconds. If server receives
6485 commands from client more frequently, timeout is registered
6486 to process the commands. Affected file silcd/command.c.
6487 Added new function silc_server_command_process_timeout.
6489 * Changed NICK_NOTIFY handling in client library to check that
6490 if the client's nickname was changed, so there is no need to
6491 resolve anything from the server.
6493 * Removed error printing from the WHOIS and IDENTIFY commands.
6494 If error occurs then it is ignored silently in the client library.
6495 The application, however, may map the received error to
6496 human readable error string. The application currently maps
6497 the NO_SUCH_NICKNAME error to string.
6499 * Made the command status message public to the application. Moved
6500 them from lib/silcclient/command_reply.c to
6501 lib/silcclient/command_reply.h. The application can map the
6502 received command status to the string with the
6503 silc_client_command_status_message function.
6505 * Added check to the server to check that client's ID is same
6506 as the Source ID in the packet the client sent. They must
6509 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Added dist-bzip hook to the Makefile.am to make bzip2
6512 compressed distributions.
6514 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Server now enforces the maximum length for the nickname and
6517 the channel as protocol specification dictates. 128 bytes for
6518 nickname and 256 bytes for channel name.
6520 * Moved the WHOIS printing to the application. The client libary
6521 does not print out the WHOIS information anymore, the application
6522 must do it. Renamed silc_client_command_reply_whois_print to
6523 the silc_client_command_reply_whois_save.
6525 The client's idle time is also sent to the application now, and
6526 the idle is shown on screen.
6528 * Added silc_client_command_reply_identify_save to save the
6529 received IDENTIFY entries.
6531 * Do not check for channel private keys in message sending and
6532 reception if the channel does not have the PRIVKEY mode set.
6533 Affected file lib/silclient/client_channel.c.
6535 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6538 just surfaced after chaning the JOIN procedure.
6540 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Added silc_client_get_clients_by_list to get client entries
6543 from Client ID list, that is returned for example by JOIN
6544 and USERS command replies. The application should use this
6545 function for example when JOIN command reply is received to
6546 resolve the clients already on the channel (library does not
6547 do that anymore as USERS command reply is not used in the JOIN
6548 procedure anymore). Affected files lib/silcclient/silcapi.h and
6549 lib/silcclient/idlist.c.
6551 * JOIN command reply and USERS command reply returns now SilcBuffer
6552 pointers instead of unsigned char pointers when returning
6553 the client list and mode list.
6555 * Added <Client ID> argument to the JOIN command reply, mainly
6556 for the server to identify for which client the command was
6557 originally sent. Updated protocol specs accordingly.
6559 * Added SilcDlist private_key pointer to the SilcChannelEntry
6560 in the client to support the channel private keys. Affected
6561 file is lib/silcclient/idlist.h.
6563 * Added SilcChannelPrivateKey argument to the function
6564 silc_client_send_channel_message so that application can choose
6565 to use specific private ke if it wants to. If it is not provided,
6566 the normal channel key is used, unless private keys are set.
6567 In this case the first (key that was added first) is used
6568 as the encryption key.
6570 * Implemented the support for channel private key handling.
6571 Implemented the following functions:
6573 silc_client_add_channel_private_key,
6574 silc_client_del_channel_private_keys,
6575 silc_client_del_channel_private_key,
6576 silc_client_list_channel_private_keys and
6577 silc_client_free_channel_private_keys
6579 Affected file lib/silcclient/client_channel.c.
6581 * Added the support for the private keys in the channel message
6582 sending and encryption and in the message reception and
6583 decryption. Affected funtions are
6584 silc_client_send_channel_message and silc_client_channel_message.
6586 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Added SKE's key verify callback to the client library's
6589 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6591 * Removed the statement that server (or router) must send USERS
6592 command reply when joining to the channel so that the client
6593 knows who are on the channel. Instead, the client list and
6594 client's mode list is now sent in the JOIN command reply to the
6595 client who joined channel. This is better solution.
6597 * Added function silc_server_get_users_on_channel and function
6598 silc_server_save_users_on_channel to the silcd/server.[ch].
6600 * Removed function silc_server_command_send_users from the
6603 * Do not show topic on the client library anymore. The topic is
6604 sent in the command reply notify to the application and the
6605 application must show the topic now.
6607 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added client searching by nickname hash into the IDENTIFY and
6610 WHOIS commands in the server as they were clearly missing from
6611 them. Affected file is silcd/command.c.
6613 * Fixed a bug in private message receiving in the client library.
6614 The remote ID was freed and it wasn't supposed, now it is
6617 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Minor fix to the channel payload; allocate the data area, as it
6620 needs to be of specific length.
6622 * If the key agreement port is zero then the operating
6623 system will define the bound port. Affected files are
6624 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6626 * Added new function silc_channel_payload_decrypt into the file
6627 lib/silccore/silcchannel.[ch].
6629 * Moved the channel message etc, check from silc_packet_decrypt
6630 to applications. The library calls now a generic
6631 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6632 when the packet is either normal or special. This was done to
6633 allow more wide range of checking that was not allowed when
6634 the code was in library. Now applications can do virtually any
6635 checks to the packet and return to the library the decision how
6636 the packet should be processed. Affected files are
6637 lib/silccore/silcpacket.[ch].
6639 Added silc_server_packet_decrypt_check to the server and
6640 silc_client_packet_decrypt_check to the client library.
6642 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6643 to send with specified source and destination information.
6645 * Channel message delivery between routers was broken after the
6646 channel key distribution was fixed earlier. The channel key
6647 was used be to distributed to other routers as well which is not
6648 allowed by the protocol. Now this is fixed and channel keys
6649 really are cell specific and the channel message delivery between
6650 routers comply with the protocol specification.
6652 * Fixed various commands in server to check also the global list
6653 for the channel entry and not just the local list. The affected
6654 file silcd/command.c.
6656 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added assert()s to buffer formatting and unformatting routines
6659 to assert (if --enable-debug) when error occurs. Affected
6660 file: lib/silcutil/silcbuffmt.c.
6662 * Changed to auto-reconnect to check whether the remote host is
6663 router and register the re-connect timeout if it is. It used
6664 to check that whether we are normal server, but router must do
6665 auto-reconnect with another router as well. Affected file
6668 * Removed the [<key len>] option from CMODE command as the cipher
6669 name decides the key length, nowadays. See the defined ciphers
6670 from the protocol specification.
6672 * Added [<hmac>] option to the CMODE command to define the HMAC
6673 for the channel. Added SILC_CMODE_HMAC channel mode.
6675 * Added [<hmac>] option for the JOIN command so that user can
6676 select which HMAC is used to compute the MACs of the channel
6679 * Added Hmac field to the Channel Message Payload. The integrity
6680 of plaintext channel messages are now protected by computing
6681 MAC of the message and attaching the MAC to the payload. The
6682 MAC is encrypted. Now, it is clear that this causes some
6683 overhead to the size of the packet but rationale for this is that
6684 now the receiver can verify whether the channel message decrypted
6685 correctly and also when private keys are set for the channel the
6686 receiver can decrypt the packet with several keys and check from
6687 the MAC which key decrypted the message correctly.
6689 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6690 lib/silccrypt/silccipher.[ch].
6692 * Added silc_hash_len to return the digest length into the
6693 lib/silcrypt/silchash.[ch].
6695 * Rewrote parts of Silc Channel Payload interface in the
6696 lib/silccore/silcchannel.[ch]. The encode function now also
6697 encrypts the packet and parse function decrypts it.
6699 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Fixed a minor formatting bug in the SKE's key material processing.
6702 It actually might have processed the keys wrong way resulting
6705 * Redefined the mandatory HMAC algorithms and added new algorithms.
6706 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6707 and hmac-md5 truncated to 96 bits. The mandatory is now
6708 hmac-sha1-96. Rest are optional (including the one that used
6709 to be mandatory). Rationale for this is that the truncated HMAC
6710 length is sufficient from security point of view and can actually
6711 make the attack against the HMAC harder. Also, the truncated
6712 HMAC causes less overhead to the packets. See the RFC2104 for
6715 * Added new [hmac] configuration section. The SKE used to use
6716 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6717 is of course wrong. The official names that must be proposed in
6718 the SKE are the ones defined in the protocol specification
6719 (hmac-sha1-96 for example). The user can configure any hmac
6720 using any hash function configured in the [hash] section. At
6721 least, the mandatory must be configured.
6723 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6725 * Added HMAC list to the SKE proposal list. It has now both
6726 hash algorithm list and HMAC list. This makes the protocol
6727 incompatible with previous versions. The SKE now seems to work
6728 the way it is supposed to work, for the first time actually.
6730 * Defined plain Hash algorithms to the protocol specification.
6733 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Implemented support for key agreement packets into the server.
6736 Added functions silc_server_key_agreement and
6737 silc_server_send_key_agreement. Other than these functions,
6738 server has nothing to do with this packet.
6740 * Added support for private message key packets into the server.
6741 Added functions silc_server_private_message_key and
6742 silc_server_send_private_message_key.
6746 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6747 called in the protocol's final callback instead in the END
6748 protocol state. This makes a little more sense and in the same
6749 time in client we can use the same protocol routines for normal
6750 key exchange and to key agreement packet handling as well.
6752 * Added to both client's and server's KE protocol context the
6753 SilcSKEKeyMaterial pointer to save the key material. We will
6754 bring the key material to the protocol's final callback by doing
6755 this. The final callback must free the key material.
6757 * Added SKE's packet_send callback into client's KE protocol
6758 context so that the caller can choose what packet sending function
6759 is used. This way we can use different packet sending when
6760 doing normal SKE when doing key agreement packet handling (in
6761 the key agreement packet handling we do not want to encrypt
6764 * Implemented the responder side of the key agreement routines
6765 in the client. The client can now bind to specified port and
6766 accept incoming key negotiation. The key material is passed
6767 to the application after the protocol is over.
6769 * Implemented the processing of incoming Key Agreement packet
6770 in the client. Added function silc_client_key_agreement to
6773 * Implemented the intiator side of the key agreement routines
6774 in the client. The client can now initiate key agreement with
6775 another remote client. The key material is passed to the
6776 application after the protocol is over.
6778 * Created client_keyagr.c to include all the key agreement
6781 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6782 SILC_TASK_CALLBACK except that it is not static.
6784 * Created client_notify.c and moved the Notify packet handling
6785 from the client.[ch] into that file.
6787 * Created client_prvmsg.c and moved all private message and
6788 private message key routines from the client.[ch] into that file.
6790 * Create client_channel.c and moved all channel message and
6791 channel private key routines from the client.[ch] into that file.
6793 * Changed silc_client_get_client_by_id_resolve to resolve with
6794 WHOIS command instead of IDENTIFY command, in the file
6795 lib/silclient/idlist.c.
6797 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Implemented the SKE's responder side to the Client library.
6801 * When FAILURE is received to the protocol do not trust it
6802 blindly. Register a timeout to wait whether the remote closes
6803 the connection as it should do it, only after that process the
6804 actual failure. This was changed to both client and server.
6806 * Added client_internal.h to include some of the structures
6807 there instead of client.h in lib/silcclient/.
6809 * Added function silc_task_unregister_by_callback to unregister
6810 timeouts by the callback function.
6812 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Some "Incomplete WHOIS info" errors has been appearing on the
6815 log files. Took away the entry->userinfo check from WHOIS
6816 reply sending. The entry->userinfo is now " " if client did not
6817 provide one. I thought this was fixed earlier but something
6818 is wrong still. Let's see if the error still appears.
6820 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Fixed a minor bug in the login when the channel key is
6823 re-generated in the server. It used to generate the key in
6824 wrong order and thus caused problems in the channel traffic.
6826 * Fixed a minor bug in channel key distsribution after
6827 KICK command. The key was not sent to the router even though
6830 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Added silc_ske_process_key_material_data as generic routine
6833 to process any key material as the SILC protocol dictates. The
6834 function is used by the actual SKE library but can be used by
6835 applications as well. This relates to the private message keys
6836 and the channel private keys since they must be processed the
6837 same way the normal SILC session keys. The protocol dictates
6838 this. Affected files: lib/silcske/silcske.[ch].
6840 Added also silc_ske_free_key_material to free the
6841 SilcSKEKeyMaterial structure.
6843 * Defined silc_cipher_set_key function to set the key for
6844 cipher without using the object's method function. The affected
6845 files: lib/silccrypt/silccipher.[ch].
6847 * Implemented silc silc_client_add_private_message_key,
6848 silc_client_add_private_message_key_ske,
6849 silc_client_del_private_message_key,
6850 silc_client_list_private_message_keys and
6851 silc_client_free_private_message_keys functions in the
6854 Added functions silc_client_send_private_message_key to send
6855 the Private Message Key payload and silc_client_private_message_key
6856 to handle incoming Private Message Key payload.
6858 * Added Cipher field to the Private Message Key payload to set
6859 the cipher to be used. If ignored, the default cipher defined
6860 in the SILC protocol (aes-256-cbc) is used.
6862 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Removed lib/silcclient/ops.h file.
6866 Redefined parts of the SILC Client Library API. Created new
6867 file silcapi.h that deprecates the ops.h file and defines the
6868 published Client Library API. Defined also private message key
6869 API and channel private key API into the file.
6871 This is the file that the application must include from the
6872 SILC Client Library. Other files need not be included by
6873 the application anymore.
6875 * Added new key_agreement client operation callback and also
6876 defined the Key Agreement library API for the application.
6878 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6881 is used by clients to request key negotiation between another
6882 client in the SILC network. If the negotiation is started it
6883 is performed using the SKE protocol. The result of the
6884 negotiation, the secret key material, can be used for example
6885 as private message key.
6887 Implemented the Key Agreement payload into the files
6888 lib/silccore/silauth.[ch].
6890 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Redefined ciphers for the SILC protocol. Added some new ciphers
6893 and defined the key lengths for the algorithms. Changed the
6894 code accordingly. The default key length is now 256 bits.
6896 * Fixed SKE key distribution function silc_ske_process_key_material
6897 when the key length is more than 128 bits. The default key
6898 length in SILC is now 256 bits.
6900 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6901 to indicate unsupported algorithm.
6903 * Renamed rijndael.c to aes.c and all functions as well.
6905 * Fixed a long standing channel key setting bug in client library.
6906 Weird that it has never surfaced before.
6908 * Fixed bug in channel deletion. If the entire channel is removed
6909 then it must also delete the references of the channel entry
6910 from the client's channel list as the client's channel entry and
6911 the channel's client entry share same memory.
6913 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Implemented CONNECT and SHUTDOWN commands in the client.
6917 * Implemented CLOSE command to the client.
6919 * Added the function silc_idlist_find_server_by_name into the
6920 files silcd/idlist.[ch].
6922 Added the function silc_idlist_find_server_by_conn into the
6923 files silcd/idlist.[ch].
6925 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6927 * DIE command was renamed to SHUTDOWN. Updated the both code
6930 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6931 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6933 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6936 * Added function silc_server_create_connection function to create
6937 connection to remote router. My server implementation actually
6938 does not allow router to connect to normal server (it expects
6939 that normal server always initiates the connection to the router)
6940 so the CONNECT command is only good for connecting to another
6943 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6946 or some other client was kicked from the channel.
6948 Implemented the handling of the notify type to both client
6951 Implemented silc_server_send_notify_kicked to send the KICKED
6952 notify. It is used to send it to the server's primary router.
6954 * Implemented the KICK command into server and client.
6956 * Added `query' argument to the silc_idlist_get_client function
6957 to indicate whether to query the client from server or not if
6960 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6961 to indicate that the client is not channel founder.
6965 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Removed the rng context from SilcPacketContext structure and
6968 changed that the packet routine uses the Global RNG API.
6970 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Added support for quit message that client can "leave" on the
6973 channel when it quits the SILC. It is ditributed inside the
6974 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6976 Added silc_server_free_client_data that will take the
6977 signoff message as argument.
6979 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6981 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6983 * Updated parts of the protocol specification to keep it up
6986 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6989 payloads in one packet.
6991 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6992 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6993 use now the new List flag.
6995 * Also deprecated the following packet types: REPLACE_ID,
6996 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6998 * Added list support for Notify packet in server.
7000 * Added silc_server_send_notify_channel_change to send the
7001 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7002 the silc_server_send_replace_id.
7004 * Added silc_server_send_notify_nick_change to send the
7005 NICK_CHANGE notify type. Deprecates the function
7006 silc_server_send_replace_id.
7008 * Added silc_server_send_notify_join to send the JOIN notify type.
7009 Deprecates the function silc_server_send_new_channel_user.
7011 * Added silc_server_send_notify_leave to send LEAVE notify type.
7012 Deprecates the function silc_server_send_remove_channel_user.
7014 * Added silc_server_send_notify_cmode and
7015 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7016 types. Deprecates the silc_server_send_set_mode function.
7018 * Added SERVER_SIGNOFF notify type to indicate that server has
7019 quit. This means that all clients on the channel from that
7020 server will drop. This can be also used when netsplit happens.
7022 Deprecated REMOVE_ID packet type since it is not needed anymore
7025 Added silc_server_send_notify_server_signoff to send the
7026 SERVER_SIGNOFF notify type. Deprecates the function
7027 silc_server_send_remove_id.
7029 Added also silc_server_send_notify_signoff to send the
7030 SIGNOFF notify type.
7032 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7033 SILC protocol from this day on. Changed the protocol
7034 specification as well.
7036 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7037 notify type. It is used between routers to notify about
7038 topic changes on a channel.
7040 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7043 * Partly updated the protocol specification to comply with the
7044 changes now made. It is still though a bit outdated.
7046 * The JOIN notify type now takes one extra argument <Channel ID>.
7047 The packet used to be destined to the channel but now the
7048 JOIN type may be sent as list thus it is impossible to
7049 destine it to any specific channel. By adding this argument
7050 it is again possible.
7052 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Added CREDITS file. The CHANGES and CREDITS file will appear
7055 in the distribution as well.
7057 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7060 types in the server's silcd/packet_receive.c.
7062 * Implemented CMODE and CUMODE to work in router environment.
7064 * Fixed minor encoding and decoding buglet from the
7065 lib/silccore/silcmode.c.
7067 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7070 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7072 * Changed all SilcConfigServer* and silc_config_server* to
7073 SilcServerConfig* and silc_server_config*, respectively.
7076 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Associated the ID (client or server ID) to the Authentication
7079 Payload to avoid any possibility of forging. Updated the
7080 protocol specification and the code accordingly.
7082 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * The RSA key length is now save to the RsaKey context in the
7085 key generation process in lib/silccrypt/rsa.c. The key length
7086 is now used to figure out the maximum size of the block allowed
7087 to be encrypted/signed.
7089 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7090 is equivalent to the silc_mp_mp2bin but does not allocate any
7093 * Changed silc_mp_mp2bin API to take length argument. If it is
7094 non-zero then the buffer is allocated that large. If zero, then
7095 the size is approximated using silc_mp_sizeinbase, which however
7098 * Created Global RNG API which is global RNG that application can
7099 initialize. After initializing, any routine anywhere in the
7100 code (including library) can use RNG without allocating a new
7101 RNG object. This was done to allow this sort of use of the
7102 RNG in code that has no chance to allocate RNG object. All
7103 applications currently allocate this and many routines in the
7104 library use this. Affected file lib/silccrypt/silcrng.[ch].
7106 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7107 it to use the Global RNG API.
7109 * Defined Authentication Payload into protocol specification that
7110 is used during SILC session to authenticate entities. It is
7111 used for example by client to authenticate itself to the server
7112 to obtain server operator privileges.
7114 Implemented this payload into the lib/silccore/silcauth.[ch].
7115 Implemented also routines for public key based authentication
7116 as the new protocol specification dictates.
7118 Moved definitions of different authentication methods from
7119 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7121 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7122 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7123 silc_pkcs_verify_with_hash functions into the file
7124 lib/silccrypt/silcpkcs.[ch].
7126 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * The client entry's userinfo pointer must be always valid.
7129 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7130 will fail since it requires the userinfo. Now, the userinfo
7131 is allocated as "" if actual userinfo does not exist. Actually,
7132 it must exist and it is totally Ok to drop client connections
7133 that does not announce the userinfo. However, we will make
7134 this workaround for now.
7136 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7137 to return the remote port by socket.
7139 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7142 SILC_SERVER_PENDING_EXEC and added an new macro
7143 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7144 data or when error occurs while processing the pending command.
7146 Added new argument `destructor' into silc_server_command_pending
7147 and to the SilcServerCommandPending object. This destructor is
7148 now called after calling the pending callback or if error occurs
7149 immediately. If error occurs the actual pending callback won't
7150 be called at all - only the destructor. The destructor may be
7151 NULL if destructor is not needed.
7153 All this applies for client library code as well. Similar
7154 changes were made there as well for the pending commands.
7156 In the client, the application must now allocate the
7157 SilcClientCommandContext with the silc_client_command_alloc
7160 * Added reference counter to the SilcServerCommandContext. Added
7161 function silc_server_command_alloc and silc_server_command_dup
7164 Same type of functions added to the client library for the same
7167 * Removed the cmd_ident from IDListData away since it is now
7168 global for all connections. It is the command identifier used
7169 in command sending and with pending commands. The affected file
7172 * Added reference counter to the SilcSocketConnection objecet to
7173 indicate the usage count of the object. The object won't be
7174 freed untill the reference counter hits zero. Currently only
7175 server uses this, and client ignores it. The client must be
7176 set to use this too later. The affected files are
7177 lib/silccore/silcsockconn.[ch]. Added also the function
7178 silc_socket_dup to increase the reference counter.
7180 This was mainly added because it is possible that the socket
7181 is removed underneath of pending command or other async
7182 operation. Now it won't be free'd and proper DISCONNECTING
7183 flags, etc. can be set to avoid sending data to connection that
7184 is not valid anymore.
7186 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7187 the connection. After that it sets SILC_SET_DISCONNECTED.
7188 It is, however, possible that the socket data is not still freed.
7189 The silc_server_packet_process now checks that data is not
7190 read or written to connection that is DISCONNECTED. The socket
7191 get's freed when the reference counter hits zero.
7193 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Changed the client operation API: channel_message operation's
7196 `sender' is now the client entry of the sender, not the nickname
7197 and the `channel' is the channel entry, not the channel name.
7199 In the private_message operation the `sender' is now also the
7200 client entry of the sender not the nickname.
7202 Affected file is lib/silcclient/ops.h and all applications
7203 using the client operations.
7205 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Moved the calling of ops->connect() from connect_to_server_final
7208 into receive_new_id functin since that is the point when the
7209 client is actually allowed to send traffic to network. The
7210 affected file is lib/silcclient/client.c.
7212 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7214 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7215 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7216 (if needs broadcasting) instead of broadcasting the packets one
7217 by one which would make a burst in the network traffic.
7219 * Added `broadcast' argument to the functions in silcd/server.[ch]
7220 silc_server_create_new_channel[_with_id] to indicate whether
7221 to send New Channel packet to primary router.
7223 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Added new function into the silcd/server.[ch] files:
7226 silc_server_create_new_channel_with_id to create new channel with
7227 already existing Channel ID.
7229 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7230 lib/silccore/silcpacket.h. This packet is used t send list of
7231 Set Mode payloads inside one packet. Server uses this to set
7232 the modes for the channels and clients on those channels, that it
7233 announced to the router when it connected to it. The protocol
7234 specification has been updated accordingly.
7236 * The silc_server_new_channel did not handle the packet coming
7237 from normal server as it normally does not send that. However,
7238 when it announces its channels it does send it. Implemented
7239 the support for that.
7241 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7242 into the file lib/silccore/id.h.
7244 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Fixed memory leaks in the functions silc_idlist_del_client,
7247 silc_idlist_del_channel and silc_idlist_del_server in the file
7248 silcd/idlist.c. All of those leaked like a sieve.
7250 * Fixed some small memory leaks in the client's function
7251 silc_client_notify_by_server.
7253 * Added functions into silcd/server.c: silc_server_announce_clients,
7254 silc_server_announce_channels and silc_server_announce_server.
7255 These functions are used by normal and router server to announce
7256 to its primary router about clients, channels and servers (when
7257 router) that we own. This is done after we've connected to the
7260 These functions effectively implements the following packet types:
7261 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7262 and SILC_PACKET_NEW_ID_LIST.
7264 * Added new functions into the silcd/packet_receive.[ch]:
7265 silc_server_new_id_list, silc_server_new_channel_list and
7266 silc_server_new_channel_user_list to handle the incoming
7267 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7269 * Added support of changing Channel ID in the function
7270 silc_server_replace_id. If the server that announces a channel
7271 to the router already exists in the router (with same name but
7272 with different Channel ID), router is responsible to send
7273 Replace ID packet to the server and force the server to change
7274 the Channel ID to the one router has.
7276 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7277 client that the Channel ID has been changed by the router. The
7278 normal server sends this to the client. Client must start using
7279 the new Channel ID as the channel's ID.
7281 Implemented handling of this new type into lib/silcclient/client.c
7282 into the function silc_client_notify_by_server.
7284 * Added new function silc_idlist_replace_channel_id into the files
7285 silcd/idlist.[ch] to replace the Channel ID.
7287 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7289 * Call silc_server_command_identify_check always when processing
7290 the IDENTIFY command in silcd/command.c
7292 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7294 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7295 send keepalive packets. The packet can be sent by clients,
7296 servers and routers.
7298 Added function silc_socket_set_heartbeat into the file
7299 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7300 If not set, the heartbeat is not performed. The actual
7301 heartbeat is implemented in the low level socket connection
7302 library. However, application is responsible of actually
7305 Added silc_server_send_heartbeat to send the actual heartbeat
7306 packet into silcd/packet_send.[ch]. Server now performs
7307 keepalive with all connections.
7309 * Added silc_task_get_first function into lib/silcutil/silctask.c
7310 to return the timeout task with shortest timeout. There was a bug
7311 in task unregistration that caused problems. TODO has been
7312 updated to include that task system must be rewritten.
7314 * The client library will now resolve the client information when
7315 receiving JOIN notify from server for client that we know but
7316 have incomplete information.
7318 * Rewrote parts of silc_server_remove_from_channels and
7319 silc_server_remove_from_one_channel as they did not remove the
7320 channel in some circumstances even though they should've.
7322 * Encryption problem encountered in server:
7324 The LEAVE command used to send the Channel Key packet to the
7325 router immediately after generating it. However, the code
7326 had earlier sent Remove Channel user packet but not immediately,
7327 ie. it was put to queue. The order of packets in the router
7328 was that Channel Key packet was first and Remove Channel User
7329 packet was second, even though they were encrypted in the
7330 reverse order. For this reason, MAC check failed. Now, this
7331 is fixed by not sending the Channel Key packet immediately but
7332 putting it to queue. However, this is more fundamental problem:
7333 packets that are in queue should actually not be encrypted
7334 because packets that are sent immediately gets encrypted
7335 actually with wrong IV (and thus MAC check fails). So, packets
7336 that are in queue should be encrypted when they are sent to
7337 the wire and not when they put to the queue.
7339 However, the problem is that the current system has not been
7340 designed to work that way. Instead, the packet is encrypted
7341 as soon as possible and left to the queue. The queue is then
7342 just purged into wire. There won't be any fixes for this
7343 any time soon. So, the current semantic for packet sending
7346 o If you send packet to remote host and do not force the send
7347 (the packet will be in queue) then all subsequent packets to the
7348 same remote host must also be put to the queue. Only after the
7349 queue has been purged is it safe again to force the packet
7352 o If you send all packets immediately then it safe to send
7353 any of subsequent packets through the queue, however, after
7354 the first packet is put to queue then any subsequent packets
7355 must also be put to the queue.
7357 Follow these rules and everything works fine.
7359 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added new function silc_server_remove_clients_by_server to
7362 remove all client entries from ID list when the server connection
7363 is lost. In this case it is also important to invalidate all
7364 client entires as they hold the invalid server entry. This
7365 fixes fatal bug when server has lost connection and will reconnect
7368 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Made some sanity checks to silc_server_daemonise like to check
7371 whether the requested user and group actually exists.
7373 * Added sanity check to SKE's silc_ske_responder_finish to check
7374 that the public and private key actually is valid.
7376 * Invalidate the client's nickname when receiving Replace ID
7377 packet and the Client ID is being replaced. This means that the
7378 server will query the nickname if someone needs it (client)
7381 * Sort the ID Cache in client library when the ID Cache data
7382 has changed (needs sorting).
7384 * Do not allow for SILC client to create several connections to
7385 several servers. The client does not support windows right now
7386 and generating multiple connections causes weird behaviour.
7388 Irssi-silc client does support windows and can handle several
7389 connections without problems, see: www.irssi.org and SILC plugin.
7391 * Fixed some places where client was added to the IDList. The
7392 rule of thumb is following (in order to get everything right):
7393 If the client is directly connected local client then the
7394 `connection' argument must be set and `router' argument must be
7395 NULL to silc_idlist_add_client function. If the client is not
7396 directly connected client then the `router' argument must
7397 bet set and the `connection' argument must be NULL to the
7398 silc_idlist_add_client function.
7400 * The funtion silc_server_packet_send_local_channel actually did
7401 not check whether the client was locally connected or not. It
7402 does that now. Fixed a bug related to LEAVE command.
7404 * Fixed Remove Channel User payload parsing bug in server's
7405 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7407 * The server's silc_server_save_channel_key now checks also the
7408 global ID list for the channel as it might not be in the local
7409 list. Fixed a bug related to LEAVE command.
7411 * Is this the end of the [<unknown>] buglet that has been lurking
7412 around for a long time? A little for loop fix in server's
7413 silc_server_command_whois_parse that is used by both IDENTIFY
7414 and WHOIS command. At least, this was a clear bug and a cause
7415 of one type of [<unknown>] buglet.
7417 * WHOIS and IDENTIFY commands call the function
7418 silc_server_command_[whois/identify]_check function even if
7419 we are not router server.
7421 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Added --with-gmp configuration option. If set the GMP
7424 is always compiled in the SILC source tree. If not set then
7425 it is checked whether the system has the GMP3 installed. If
7426 it has then the GMP won't be compiled (the system's headers
7427 and library is used), if it doesn't have it then the GMP is
7428 compiled in the SILC source tree.
7430 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Changed RSA private exponent generation to what PKCS #1
7433 suggests. We try to find the smallest possible d by doing
7434 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7435 not security fix but optimization.
7437 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Added new config entry [Identity] to fork the server and run
7440 it as specific user and group. A patch from Bostik.
7442 * Imported Dotconf configuration library into lib/dotconf.
7443 This will be used to create the SILC configuration files later.
7444 It will appear in the distsribution after this commit.
7446 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * A big code auditing weekend happening. Auditing code for
7449 obvious mistakes, bugs and errors. Also, removing any code
7452 Removed files for being obsolete:
7454 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7455 inline in the file lib/silcutil/silcbuffer.h)
7457 o lib/silcutil/silcbufutil.c (the header has inline versions)
7459 Changed code to fix possible error conditions:
7461 o The buffer formatting routines now check that the destination
7462 buffer really has enough space to add the data. This applies for
7463 both buffer formatting and unformatting
7464 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7465 unformatting was changed to accomodate following rules:
7466 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7467 sent to the function while XXX_*STRING will not allocate or copy
7468 the data into the buffer. Instead it sets the pointer from the
7469 buffer into the pointer sent as argument (XXX_*STRING used to
7470 require that the pointer must be allocated already). This change
7471 makes this whole thing a bit more consistent and more optimized
7472 (note that the data returned in the unformatting with XXX_*STRING
7473 must not be freed now). The routines return now -1 on error.
7475 o Tried to find all code that use buffer_format and buffer_unformat
7476 and added return value checking to prevent formatting and
7477 especially unformatting errors and possible subsequent fatal
7480 o Changed ske->x and ske->KEY to mallocated pointers in
7481 lib/silcske/silcske.h. Fixed possible data and memory leak.
7483 o Added return value checking to all *_parse* functions. Fixed
7484 many memory leaks as well.
7486 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7487 so that buffer overflows would not happen. All code now also
7488 checks the return value as it can fail.
7490 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Added reconnection support to server if the normal server looses
7493 its connection to the router (for example if router is rebooted).
7494 The server performs normal reconnection strategy implemented
7495 to the server. Affected file silcd/server.c.
7497 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added new packet type SILC_PACKET_SET_MODE that is used to
7500 distribute the information about changed modes (for clients,
7501 channels and clients channel modes) to all routers in the
7502 network. Updated the protocol specification accordingly.
7504 Added functions into silcd/packet_send.c and
7505 silcd/packet_receive.c: silc_server_send_set_mode,
7506 silc_server_set_mode.
7508 Added new files silcmode.[ch] into lib/silccore that implements
7509 the encoding and decoding of Set Mode Payload. Added new type
7510 SilcSetModePayload. Moved the definitions of different modes
7511 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7513 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Oops, a little mistake in server's connection authentication
7516 protocol. The protocol is not ended with FAILURE but with
7517 SUCCESS if the authentication is Ok. :) Affected file is
7520 * Implemented NICK_CHANGE notify handling in server in the file
7521 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7522 the local clients on the channel. After the changing nickname
7523 in router environment snhould work and the [<unknown>] nickname
7524 should appear no more.
7526 The silc_server_replace_id function that receives the Replace ID
7527 payload now sends the NICK_CHANGE notify type also in the file
7528 silcd/packet_receive.c
7530 * Changed WHOIS and IDENTIFY command to support the maximum amount
7531 of arguments defined in protocol specs (3328 arguments). This
7532 fixed a bug that caused problems when there were more than three
7535 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Added extra parameter, command identifier, to the
7538 silc_client_send_command so that explicit command identifier
7541 Changed that ID list routines uses specific command identifier
7542 when sending WHOIS/IDENTIFY requests to the server so that they
7543 can be identified when the reply comes back.
7545 Affected files lib/silcclient/command.[ch],
7546 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7548 * Added `sender' argument to silc_server_packet_send_to_channel
7549 to indicaet the sender who originally sent the packet to us
7550 that we are now re-sending. Ignored if NULL. Affected file
7551 silcd/packet_send.[ch].
7553 * Added some server statistics support in silcd/server_internal.h
7554 SilcServerStatistics structure and around the server code. Also
7555 send some nice statistics information when client is connecting
7558 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Fixed channel ID decoding in server's JOIN command reply in
7561 silcd/command_reply.c
7563 * Fixed braodcasting of replace ID payload to not to send it if
7564 we are standalone server in silcd/packet_receive.c.
7566 * Fixed all channel message sending routines to not to send
7567 packets to clients that has router set, since they are routed
7568 separately in the same function earlier. Affects file
7569 silcd/packet_send.c and all channel packet sending functions.
7571 * In USERS reply, res_argv[i] are not allocated, the table
7572 is allocated. Thus changed that free the table, not its
7575 * In server's whois_check and identify_check if the client is
7576 locally connected do not send any WHOIS commands - they are not
7579 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7581 * Fixed some minor bugs in client when sending WHOIS command. The
7582 arguments was in wrong order.
7584 * Removed statis function add_to_channel from server in
7585 silcd/command.c that was previously used with the joining but
7588 * Tested USERS command in router environment successfully with two
7589 routers, two servers and two clients.
7591 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Reorganized the USERS command and command reply in client library
7594 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7595 When the command is given by user we register a pending command
7596 callback that will reprocess the command after the reply has been
7597 received from the server. When reprocessing the packet we then
7598 display the information. Thus, the USERS information is displayed
7599 now in the command callback instead of in the command reply
7600 callback. The processing of the command is same as previously
7601 when server has sent the command reply in the JOINing process.
7603 * Added to USERS command in silcd/command_reply.c to join the client,
7604 we didn't use to know about, to the channel after we've created
7605 a client entry for it. Also, for clienet we did know already still
7606 check whether it is on the channel or not and add it if not.
7608 * Removed silc_server_command_join_notify as the function and its
7611 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Changed the client's pending command handling to the same as the
7614 server's pending command handling. It is also now possible to
7615 execute command reply functions from other command reply
7616 function as the function callbacks for commands and command
7617 replies are one and same. The pending commands are not static
7618 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7619 in client connection context. Thus, pending commands are server
7620 connection specific as it is convenient.
7622 Changed the function silc_client_command_pending and
7623 silc_client_command_pending_del and added new function
7624 silc_client_command_pending_check. Removed the
7625 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7628 * Added cmd_ident, current command identifier, to the client
7629 connection context in lib/silcclient/client.h to keep track on
7630 command identifiers used in command sending. Client's command reply
7631 function handling now supports the mandatory command identifiers.
7633 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7634 funtions in client to fully support pending command callbacks.
7636 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7637 as one of the arguments to the application in the command reply
7640 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7641 before first releasing SILC but came back. Now it is removed again
7642 and should come back nomore. The FORWARDED flag was used only
7643 by the JOINing procedure by forwarding the command packet to router.
7644 Now, the JOINing procedure has been changed to more generic (due
7645 to various router environment issues) and FORWARDED is not needed
7646 anymore for anything. The protocol specification is yet to be
7649 Now, removed silc_server_packet_forward from server and the flag
7650 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7652 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7654 * Renamed NAMES command to USERS command. The NAMES was named that
7655 due to historical reasons. Now it is renamed. Also, rewrote
7656 parts of the USERS command. The nickname list is not sent anymore
7657 by the server. Only Client ID and mode lists are sent in the USERS
7658 command. Changed this also to the protocol specification.
7660 The client now resolves the names and stuff after it receives
7661 the USERS list from the server when joining to the channel.
7663 * WHOIS and IDENTIFY commands has been changed to support multiple
7664 Client ID's per command. One can now search for multiple users
7665 in the network by sending only one WHOIS or IDENTIFY command.
7666 Changed the code and the protocol specifications.
7668 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7669 uses silc_server_command_whois_parse to parse the request. */
7671 * If normal server, do not parse the WHOIS and IDENTIFY requests
7672 before sending it to the router. Saves some time.
7674 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7676 * Fixed JOIN command on client library. Wrong number of arguments
7677 used to crash the client.
7679 * Added silc_server_channel_has_global function to check whether
7680 channel has global users or not.
7682 * Added silc_server_channel_has_local function to check whether channel
7683 has locally connected clients on the channel.
7685 * The silc_server_remove_from_one_channel now checks whether the
7686 channel has global users or not after given client was removed from
7687 the channel. It also checks whether the channel has local clients
7688 on the channel anymore. If it does not have then the channel entry
7689 is removed as it is not needed anymore.
7691 * The silc_server_notify now checks on JOIN notify whether the joining
7692 client is one of locally connected or global. If it is global then
7693 the channel has now global users on the channel and that is marked
7694 to the channel entry. Also, it now saves the global client to
7695 global list who is joining and JOINs it to the channel. This is
7696 for normal server, that is.
7698 Changed silc_server_send_notify_on_channel,
7699 silc_server_packet_relay_to_channel and
7700 silc_server_packet_send_to_channel check if we are normal server
7701 and client has router set (ie. global client) do not send the
7702 message to that client, as it is already routed to our router.
7704 * Implemented LEAVE notify type handling in silc_server_notify
7707 * Tested LEAVE command in router environment successfully. Tested
7708 with two routers, two servers and two clients.
7712 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7714 * Implemented SIGNOFF notify type handling in silc_server_notify
7717 * silc_server_remove_id now removes the client entry from all channels
7718 it has joined and thusly sends SIGNOFF notify type.
7720 * Rewrote the NAMES list generation in server by removing two excess
7721 loops. The lists are created now inside one loop.
7723 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7725 * silc_server_remove_channel_user checks now also global list
7726 for channel and client.
7728 * silc_server_new_channel_user checks now both local and global
7729 list for channel and client. Fixed a bug in client id decoding.
7730 Used to decode wrong buffer.
7732 * silc_server_channel_message checks now both local and global
7733 list for channel entry.
7735 * Tested channel joining (hence JOIN) in router environment
7736 successfully. Tested with two routers, two servers and two
7739 * Tested channel message sending in router environment successfully.
7741 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7743 * Added silc_server_save_channel_key into server.[ch] to save the
7744 received channel key in Channel Key payload processing. It is
7745 also used in JOIN command reply handling.
7747 Equivalent function silc_client_save_channel_key added into
7748 client.[ch] into client library.
7750 * Changed JOIN command reply to send information whether the channel
7751 was created or not (is existing already) and the channel key
7752 payload. Changed protocol specs accordingly.
7754 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7755 the request was sent by ID and not by nickname. Crashed on
7758 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7761 now correctly save the received data.
7763 * silc_server_free_sock_user_data now notifies routers in the
7764 network about entities leaving the network.
7766 At the same time implemented functions silc_server_remove_id
7767 and silc_server_send_remove_id to receive and send REMOVE_ID
7768 packets. The packet is used to notify routers in the network
7769 about leaving entities. The ID removed will become invalid in
7772 * Added function silc_idlist_del_server into server. Removes and
7773 free's server entry from ID list.
7775 * silc_server_private_message function now checks, if we are router,
7776 that the destination ID really is valid ID, naturally.
7778 * In router when NEW_ID packet is received (for new client) the
7779 hash of the Client ID is saved in the ID Cache but the
7780 client->nickname is set to NULL, instead of putting the hash
7783 IDENTIFY command now also checks that client->nickname must be
7784 valid. If it is not if will request the data from the server who
7785 owns the client. Added new function
7786 silc_server_command_identify_check.
7788 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7789 to set the command to already allocated Command Payload.
7791 * Tested private message sending in router environment with two
7792 routers, two servers and two clients. Fixed minor bugs and now
7795 * Fixed segfault from client's NAMES command. Used to crash if
7798 * Forwarded packets must not be routed even if it is not destined
7799 to the receiver. Changed server code comply with this.
7801 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * Added `require_reverse_mapping' boolean value to ServerParams
7804 structure. If TRUE (not default) the server will require that
7805 the connecting host has fully qualified domain name.
7807 If the reverse mapping is not required and hostname could not be
7808 found the IP address is used as hostname.
7810 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Implemented version string checking to both client and server.
7813 The check is incomplete currently due to the abnormal version
7814 strings used in development version of SILC.
7816 * Changed all command functions in server to use the new
7819 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * Changed char *data to unsigned char *data in ID Cache system to
7822 support binary data as ID Cache data. Changed code to support
7823 binary data in lib/silccore/idcache.c.
7825 * Renamed silc_server_packet_relay_command_reply to
7826 silc_server_command_reply as it is normal packet receiving
7827 function. Rewrote the function to accept command replys for
7828 servers and not only for clients.
7830 * Mark remote router always as registered server if we are connecting
7831 to it. Otherwise, commands sent by the router to us are ignored.
7833 * All ID List find routines now returns the ID Cache Entry pointer
7834 as well if requested.
7836 * WHOIS command works now in router environment, tested with two
7837 routers, two servers and two clients.
7839 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7840 in router environment (as it is almost equivalent to WHOIS) but
7841 hasn't been tested thoroughly. Added new functions:
7843 silc_server_command_identify_parse
7844 silc_server_command_identify_send_reply
7845 silc_server_command_identify_from_client
7846 silc_server_command_identify_from_server
7848 * Disabled route cache adding because adding two different ID's with
7849 same IP replaces the old cache entry thus giving wrong route.
7850 The entry->router->connection is always the fastest route anyway
7851 so route cache may not be needed. Of course, new routes maybe
7852 established after receiving the ID when the entry->router->connection
7853 might not be anymore the most optimal.
7855 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7857 * Add route cache for received ID for fast routing.
7859 * Added silc_server_packet_route to route received packet on router
7860 that is not destined to us.
7862 * Renamed silc_server_get_route to silc_server_route_get.
7864 * Added id_string and id_string_len fields into SilcServer to
7865 include encoded ServerID for fast comparing without excess
7866 encoding of the ID's.
7868 * Cleaned up WHOIS command on server side. Added following static
7871 silc_server_command_whois_parse
7872 silc_server_command_whois_check
7873 silc_server_command_whois_send_reply
7874 silc_server_command_whois_from_client
7875 silc_server_command_whois_from_server
7877 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7878 arguments in command replies. All command functions should be
7879 updated to use this macro.
7881 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Minor typo fixes on command reply handling on server.
7885 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * Added silc_server_command_add_to_channel internal routine to add
7888 the client to the channel after router has created the channel and
7889 sent command reply to the server.
7891 * Added generic silc_server_send_command to send any command from
7894 * Use static buffer with ID rendering instead of duplicating data.
7896 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7898 * Fixed a channel user mode bug when joining to a channel server gave
7899 everybody channel founder rights, oops.
7901 * We mark ourselves as the router of the incoming server connection
7902 if we are router ourselves. This way we can check in some packet
7903 sending functions whether it is locally connected server. For
7904 incoming router connections we put NULL.
7906 * For router sending packets locally means now always sending the
7907 packet cell wide; to local clients and local servers. For normal
7908 server sending packet locally means sending it to only local
7911 * Fixed the JOIN command to really work in router environment. If the
7912 channel is created it is always created by the router. Router is
7913 also responsible of making the initial joining to the channel,
7914 sending JOIN notify to the sending server and distributing
7915 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7916 does not exist server doesn't do anything else but forward the
7917 command to the router which performs everything.
7919 * Added silc_server_send_channel_key function to send the Channel Key
7922 * Added silc_server_create_channel_key to create new channel key. The
7923 channel key is now re-generated everytime someone joins or leaves
7924 a channel, as protocol dictates. Note: channel->key_len is the
7927 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7930 packet_receive.[ch] to separate packet sending and receiving
7931 routines. The server.[ch] now includes everything else including
7932 actual packet processing (writing and reading data) and other
7935 Renamed silc_server_private_message_send_internal to
7936 silc_server_send_private_message. The routine is still though
7937 used only to relay private messages as server does not send
7938 private messages itself.
7940 Renamed silc_server_new_channel to silc_server_create_new_channel
7941 and added new function sicl_server_new_channel that handles the
7942 incoming New Channel packet. Added also new sending function
7943 silc_server_send_new_channel to send New Channel Payload.
7945 * Added new function silc_server_notify to process incoming notify
7946 packet to the server/router. Server may then relay the notify
7947 to clients if needed.
7949 * Added new function silc_server_new_channel_user to process incoming
7950 New Channel User packet. Router will redistribute the packet and
7951 send JOIN notify to its local clients and locally connected servers
7952 if needed. Normal server will send JOIN notify to its local client
7953 on same channel when received this packet. Added also corresponding
7954 sending function silc_server_send_new_channel_user to sent the
7957 * Added boolean route argument to send_notif_to_channel and
7958 packet_send_to_channel functions to attempt to route the packet
7959 if it is TRUE and send only locally if it is FALSE.
7961 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * silc_server_replace_id now broadcasts the received replace ID
7964 packet if it is not broadcast packet already. The router must
7965 broadcast to inform other routers about changed ID.
7967 * Added backpointer to server's router into SilcServer context in
7968 silcd/server_internal.h.
7970 * Fixed silc_server_packet_broadcast to send correct broadcast
7973 * The channel key is now distributed to the local client as soon
7974 as it is received from the router (in router environment) so that
7975 no other packet may be sent for the channel until client has
7978 * silc_server_remove_channel_user now broadcasts the received
7979 Remove Channel User packet if it is not broadcast packet already.
7980 The router must broadcast to inform other routers about removed
7983 * Added users field into SilcPacketContext that is a reference count
7984 of the context. One can increase the reference count by calling
7985 silc_packet_context_dup which is now changed to just increase the
7986 reference count instead of duplicating the data. The reference
7987 count is decresed by calling silc_packet_context_free that will
7988 free the data after the reference count hits zero.
7990 For now on the packet context and everything allocated into it
7991 (including the raw packet from network) must be freed by calling
7992 the new silc_packet_context_free function. Added also new function
7993 silc_packet_context_alloc that must be used now to allocate the
7994 context. This also means that if a routine is asynchronous from
7995 silc_[client/server]_packet_parse_type the packet context must
7996 be duplicated by calling silc_packet_context_dup. Otherwise it
7997 gets free'd after silc_[client/server]_packet_parse_type returns.
7998 Also, one must remember that if packet is duplicated then its
7999 reference count must be decresed by calling the free function as
8000 many times as it was duplicated.
8002 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8003 from both client and server.
8005 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8007 * Made joining to a channel working in router environment.
8009 * Cleaned up JOIN command on server side and create function
8010 silc_server_command_join_channel internal routine to make the
8013 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Changed silc_command_pending list to SilcDList. Also, added
8016 `ident' field to SilcServerCommandPending structure to identify
8017 the reply and to call correct callback.
8019 Added silc_server_command_pending_check function to replace the
8020 corresnponding macro. The silc_command_pending list is not
8023 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8024 to set identifier to previously allocated Command Payload. It
8025 is used to set identifier for command when resending Command
8028 * Added silc_command_payload_encode_payload to encode Command
8029 Payload buffer from SilcCommandPayload structure.
8031 * Added silc_argument_payload_encode_payload to encode Argument
8032 payload buffer from SilcArgumentPayload structure.
8034 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Changed WHOIS command to support router connection on server side.
8037 The whois request is always sent to router unless the server is
8038 standalone server. After server has received the reply from the
8039 router will it send the reply to the client.
8041 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8042 broadcast received broadcast packet. The function is used only
8043 by router. The broadcast packet is always sent to the router's
8046 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8047 render given ID to printable string, for log files for example.
8049 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * Made basic router to router connections working. At least they
8052 can now connect to each other but nothing really works the way
8053 they are supposed - yet.
8055 * Added new initiator token to RouterConnection configuration
8056 file in silcd/serverconfig.[ch]. It is used to tell whether we
8057 are the initiator to the remote router or whether we'll expect
8058 the other end to connect.
8060 * Moved registering of listener task to silc_server_init, hence
8061 the server starts listenning as soon as it is run, even if it
8062 does not have connections to other routers. Let's see how well
8065 * Changed default connection retry timeouts for more suitable in
8068 * Removed cipher and such arguments from silc_idlist_add_client
8069 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8070 Added new function silc_idlist_add_data to add the keys and stuff
8073 * Added SilcIDListData structure and added it to SilcClientEntry
8074 and SilcServerEntry as their first field in the structure. This
8075 way we can explicitly cast the ID entries to the SilcIDListData
8076 structure and get common data for the entries. In past, we had
8077 to first check what type of connection it is and then cast it to
8078 correct ID entry type. Now, we can directly cast the opaque
8079 pointer to the SilcIDListData (no matter what ID entry it actually
8080 is) and get the data needed.
8082 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8085 in some circumstances even if threre were timeout tasks, though not
8086 IO tasks, but tasks anyway. Now fixed.
8088 * Defined SilcServerConnection structure to hold connection specific
8089 stuff about directly connected servers and routers. The definition
8090 is currently in silcd/server_internal.h. I thought about having
8091 a bit more important role fro this struct but for now it is used
8092 only when connecting to other server (or router actually).
8094 * Added connecting retry support in server when connecting to
8095 router(s). The retry feature implement exponential backoff
8096 algorithm. Also, added SilcServerParams structure to hold default
8097 parameters for server. For now, it include these retry settings
8098 and are hard coded. After server is moded to be as Silc Server
8099 Library this structure will be more important.
8101 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8103 * Changed client librarys channel->clients table to SilcList and
8104 changed code accordingly.
8106 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8108 * Changed client's channel table to SilcList and changed code
8109 accordingly. Also changed SilcChannelClientEntry to include back-
8110 pointer to the channel so that client entry can use that structure
8111 as list as well and we have fast cross-reference to the channel.
8112 This change dramatically decreased the complexity of channel
8113 handling with client entry and vice versa (removed one extra
8114 loop when searching for channel entry from many functions).
8116 * Changed server->sim from table to SilcDList and changed code
8119 * NAMES command can now be used from user interface. It will show
8120 the user list on the channel, neatly.
8122 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8123 Code now saves realname of the user if it becomes available.
8125 * Renamed configure.in to configure.in.pre and made ./prepare
8126 script to automatically add correct version string to
8127 configure.in which it creates from configure.in.pre.
8129 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * NAMES command reply now shows users mode with the nickname when
8134 * Moved silc_client_ch[u]mode[_char] functions from
8135 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8136 place sucks, they are utility functions and should be in some
8139 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8141 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8144 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Added TRQ (efficient deque and list library) into lib/trq. This is
8149 a very good list library that is currently used in the SILC. Defined
8150 SilcList API over the library because I didn't like the API very
8151 much. See lib/trq/silclist.h for the API and examples of how to
8152 use the API. Fixed various places in the code to use the new
8153 SilcList API. The SilcList is meant for lists that has a structure
8154 already defined as a list. It is not suitable to add just some
8155 context to the list (in TRQ, the context is the list actually).
8157 So, I defined SilcDList that can be used for the purpose where
8158 predefined list structure does not exit. This can be used as
8159 such list. Now some context just can be added to the SilcDList.
8160 Currently this list is not used in the SILC just yet, though there
8161 are a lot places where this can replace dynamically allocated
8162 tables and I will fix these places, later, to use SilcDList.
8163 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8164 and use TRQ internally).
8166 Also fixed some annoying warning messages that the original TRQ
8167 code generated. Also minor changes to TRQ's Makefile.in.
8169 * Added support for querying by Client ID to both WHOIS and
8170 IDENTIFY commands into server, as required by the protocol.
8172 * Removed method function pointers from SilcBuffer structure. They
8173 weren't used to anything and just increased the context size for
8174 no good reason. This change also made silc_buffer_alloc and
8175 silc_buffer_free functions inline functions.
8177 * Disabled command flooding detection support until it's fixed so
8178 that it accepts commands in but does not execute them more than once
8181 * Added silc_net_localhost(), to return local hostname, into
8182 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8183 that must be initialized before calling silc_client_init.
8185 * Added new function: silc_server_send_notify_on_channels to send
8186 notify messages to all channels client has joined. It is assured
8187 that the message is sent only once per client.
8189 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8190 lib/silcutil/silcutil.[ch] as silc_format function. The new
8191 function is generic and is used by server as well, not only by
8192 the logging routines.
8194 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8195 the provided version string was not acceptable. Added new function:
8196 silc_ske_check_version into lib/silcske/silcske.h. The function
8197 must be implemented by the application (client or server) and it
8198 does not reside in the SKE library. The function checks the version
8199 string remote end sent.
8201 * Added back pointers (to opaque context and to SilcSocketConnection)
8202 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8204 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8205 duplicate packet context structure.
8207 * Changed `notify' client operation to send same arguments as client
8208 receives from server except for ID's. ID's are mapped to correct
8209 ID entry and that is returned. Also, if channel entry is not sent
8210 by server but the notify is for channel the channel entry is sent
8211 to application (otherwise application doesn't know that it is for
8212 channel (library gets it from packet's Destination ID)).
8214 * Added silc_client_remove_from_channels into client library to
8215 remove a client from all channels it has joined to. Used when
8216 received SIGNOFF notify from server. Added also new function
8217 silc_client_replace_from_channels to replace old ID entry with
8218 new ID entry on all channels. Used when received NICK_CHANGE
8221 * Fixed ID Cache list handling in silc_idlist_get_client in
8222 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8223 to get (or query) client by ID.
8225 * Updated TODO list.
8227 * Added connection authentication status message defined by the
8228 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8229 support for these into the code in client and server side.
8231 * Added generic function silc_client_send_command to send any command
8232 with variable argument list. Application should use this function
8233 to send commands if the command functions provided by the library
8234 does not suite for the application's user interface needs.
8236 * Added new `failure' client operation. Application is notified about
8237 received failure packet if client is executing a protocol. In this
8238 case the protocol's execution has failed.
8240 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8241 is required by the protocol.
8243 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8244 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8247 * Added status flag to SilcSKE object to indicate realtime status
8248 of the SKE protocol.
8250 * Application receives now exactly same command reply arguments as
8251 the library receives from server. However, if ID is received the
8252 corresponding ID entry is returned to the application (eg. Client
8253 ID is mapped to correct SilcClientEntry entry and that is returned).
8254 Changed command_reply client operation due to this change.
8256 * Changed all ID's in commands and in command replys as ID Payloads.
8257 Change affected both client and server side codes.
8259 All ID's sent in SILC network (with execption of ID's in SILC
8260 Packet header) are sent in ID Payload to support variable length
8263 * Server now notifies nick changes and notifies all clients on
8264 the channels about the new nickname (about the new Client ID,
8267 * Implemented CMODE command to change channel modes. Supports all
8268 channel modes defined by the protocol specs except ban and invite
8269 lists. (Also, private channel key mode is supported but support for
8270 setting private channel key in client is missing, thus, this mode
8271 has no effect on client side (except that server requires that the
8272 client uses private channel key and normal channel traffic does not
8275 Also, invite mode works per se, but INVITE command does not work
8276 yet correctly, so you can set channel as invite only channel but
8277 inviting clients to the channel does not work (it is yet to be
8278 thought what's the best way to do it).
8280 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8281 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8282 Implemented CUMODE command to change user's mode on the channel.
8283 Supports all modes defined by the protocol specs.
8285 * Added NAMES command reply to return users modes on the channel.
8287 * Removed unnecessary and slow ciphers from lib/silccrypt.
8289 * Set SO_KEEPALIVE option to connection sockets by default.
8291 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8293 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8294 redefined the Notify Payload into protocol specs.
8296 * Added silc_id_payload_parse_id to get ID directly from raw
8299 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8301 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8302 accept searching by Client ID as well.
8304 * Added support for LEAVE and SIGNOFF notify types in client library.
8306 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8307 to parse ID Payload from raw data.
8309 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Added flags parameter into silc_ske_assemble_security_properties
8312 function in lib/silcske/silcske.[ch].
8314 * Changed notify client operation to fit better for notify messages
8315 sent by server. The notify payload received from server is now
8316 passed to the application (after parsing it to SilcNotifyPayload).
8317 It is application's responsibility to retrieve the arguments
8318 from the payload and show the message the way it wants. The message
8319 sent by server is implementation specific.
8321 * Changed public keys to comply with the protocol specification.
8322 Old public keys are not supported anymore and are not compatible.
8324 * Removed nickname from Channel Payload as the latest draft removed
8325 it. The client must resolve the nickname from the NAMES command
8326 reply received when it joined the channel.
8328 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8330 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Fixed some errors in protocol specification drafts.
8334 * Created lib/silccore/silcnotify.c to implement Notify Payload
8335 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8336 generic payloads described by protocol specifications. The file
8337 includes implementations for ID Payload and Argument Payload.
8339 * Changed Command Payload implementation to use the new Argument
8340 Payload. Changed command_xxxx_payload to command_payload_xxxx
8341 to comply with SILC coding conventions.
8343 * Added suppport for Argument Payload handling in Notify Payload
8344 implementation as protocol requires it. Added the new support
8345 into server and client lib as well.
8347 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8349 * Added support for multiple nicknames on same channel. [n] is
8350 added locally to the nickname if there are more than one same
8351 nicknames on the channel.
8353 * Server now sends all nicknames that matched WHOIS request.
8354 Client also shows the list received from server.
8356 * Added TOPIC command to client side. User can now set and show
8357 current topic on channel.
8359 * Added MOTD command to client and server. Also, server sends the
8360 motd when client connects to the server.
8362 * Changed version strings to comply ISO 8601.
8364 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * Fixed protocol error handling in client library. It should now
8367 cope even if the SKE fails for some reason.
8369 * Made new protocol specification drafts for submitting to IETF.
8371 * Implemented TOPIC command to server in silcd/command.c.
8373 * Added two new notify types into lib/silccore/silcnotify.h:
8374 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8375 notify nickname change and topic setting/change on a channel.
8377 * API change of command_reply operation in client library. The
8378 application gets now the status type received from server as well.
8380 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8382 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8384 * Cras fixed and optimized the packet handling even further and
8385 it should work now. Minor change to the prototype of function
8386 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8388 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8390 * Added new function into lib/silcutil/silcschedule.[ch]:
8391 silc_schedule_with_fd to select() a specified fd. The function
8392 returns after timeout expires or data arrives or goes. The
8393 function is used by packet routines to wait that all data is
8394 received from network.
8396 * Fixed data reading from network in lib/silccore/silcpacket.c.
8397 The code now assures that all data is read from the fd and then
8398 continues packet processing. This was a bug fix since the code
8399 used to drop some data in some circumstances.
8401 * Added new function into lib/silcclient/client.[ch]:
8402 silc_client_start_key_exchange to start key exchange after
8403 connection has been established to server. The code internally
8404 now uses this funtion but its main purpose was to provide it
8405 for applications that perform their own connecting. After
8406 application has created a connection it merely calls this
8407 function to start the key exchange between client and server.
8408 The library takes care of everything else after that.
8410 Updated also lib/silcclient/README to explain the usage of
8413 * Do not send to application information that connection has
8414 been established. Application gets notified it by connect
8417 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8419 * Applied cras's patch to add silc_schedule_one function. The
8420 function runs scheduler once and returns.
8422 * Fixed the scheduler after cras messed it up. The timeout
8423 handling works now as it's supposed to work.
8425 * Added into lib/silccore/ silcnotify.h to include notify
8426 message types support. Changed silc_server_send_notify*
8427 functions, in server.[ch], to support those new notify types.
8428 Added the support for the notify types into client library,
8429 as well. Added new notify client operation into ops.h in
8432 * Changed silc_server_packet_send_to_channel to send normal
8433 packets instead of just channel message packets. The function
8434 is now used to send the notify packets to channels. It is not
8435 used to send channel message packets anymore, as server never
8438 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8439 va_arg()s as it seems to require it nowadays. I guess, if SILC
8440 is compiled with older va_arg() the new code should work anyway.
8442 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Splitted core library. Core library (lib/silccore) includes
8445 now only SILC protocol specific core (and common) components.
8446 Created new utility library (lib/silcutil) that includes more
8447 generic purpose stuff. The stuff for util library was taken
8448 from the old core library. This was minor and easy split.
8450 * Created SILC Client Library (lib/silcclient) that includes
8451 implementation of the SILC client without user interface. This
8452 was major move from silc/ directory. The code has been changed
8453 so that it is transparent towards the user interface. The
8454 silc/ directory includes now the same user interface as before
8455 and it uses the new client library. Read lib/silcclient/README.
8456 Basicly, the client library performs everything else related
8457 to SILC except user interface handling. Also, configuration
8458 files are considered to be part of user interface and library
8459 does not handle them.
8461 This change also changed a lot of structures, function naming etc.
8462 Most important change was that SilcClientWindow object was
8463 renamed to SilcClientConnection in the client library. Created
8464 also new file lib/silcclient/ops.h. Also added new files
8465 silc/local_command.[ch] and silc/client_ops.[ch].
8467 All these changes were made to make it easier for user interface
8468 designers to create what ever user interface for the SILC client
8471 It is also expected that the server will be moved to lib
8472 directory as well and SILC Server Library will be created;
8473 sometimes in the future.
8475 * Removed Local commands from lib/silccore/silccommand.h as
8476 they are application specific and new client library does not
8477 handle any of those anymore.
8479 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8480 old client implementation in silc/.
8482 * Added support for callback functions in SILC_LOG_* macros.
8483 Application can now set its own callbacks that will be called
8484 instead of using the default functions that will always print
8485 the debug messages to stderr (or stdout). Also, debugging can
8486 now be disabled by setting silc_debug to FALSE and re-enabled by
8487 setting it to TRUE. Note, that logging will still work even
8488 if debugging is disabled.
8490 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8491 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8492 silc_log_reset_debug_callbacks.
8494 * To enable debugging in silc client one must give now -d
8495 option on command line.
8497 * Changed silc_schedule_init to automatically allocate task queues
8498 if they are not allocated before calling it.
8500 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8502 * Added GMP 3.1 into math library.
8504 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8507 a channel in SILC network. The packet is used by servers and
8508 routers to notify other routers that user has left a channel.
8509 This little feature was missing until now. Added the feature
8510 to protocol specification as well.
8512 Added functions: silc_server_send_remove_channel_user and
8513 silc_server_remove_channel_user into server.[ch].
8515 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8516 lib/silccore/silcpacket.h. However, they are not implemented
8519 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8521 * Fixed joining to a channel and sending channel messages
8522 between server and router. The channel message sending should
8523 now work inside a cell.
8525 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8527 * Fixed the private message sending between server and router.
8528 The private message sending should now work inside a cell.
8530 * Added silc_server_replace_id into server.[ch] to replace
8531 existing ID in the SILC network.
8533 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8534 and silc_idlist_replace_server_id into idlist.[ch] in server.
8536 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8538 * Fixed the server to server connections. Server can again now
8539 connect to router. Router to router connections probably does
8542 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8544 * Added dynamic protocol registering support. Now protocols can
8545 registered and unregistered on the fly. Patch by cras.
8547 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8549 * Added lib/contrib directory to hold routines that some platforms
8550 don't have but are needed by SILC.
8552 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8553 into lin/contrib to provide getopt() and getopt_long() for
8554 those who don't have it.
8556 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8558 * Added AWAY command to client. When away message is set and
8559 client receives a private message packet the client automatically
8560 replies to the sender with the away message.
8562 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8563 bug seemed to be the cause of recent problems when compiling
8566 * Added version detection support to SKE protocol specification
8567 and added the new changes to the SKE implementation as well.
8568 There were other minor changes in the SKE protocol as well.
8570 Many changes in lib/silcske/silcske.[ch] and in
8571 lib/silcske/payload.[ch].
8573 * Added ^U functionality, clear input line. Patch from cras.
8575 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8577 * Mainly small bugfixes on core library. Fixed some debugging
8578 logging and buffer overflow in silclog.c.
8580 * Updated config.sub and config.guess on the distribution tree.
8582 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8584 * Added command lagging support in server. Client may execute
8585 commands now only once in two seconds.
8587 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8589 * Optimized packet reception. MAC computation and checking is now
8590 also more optimized. A lot previously duplicated code is now
8591 used as generic by both client and server.
8593 * Fixed key pair generation in clientutil.c
8595 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8597 * Added into lib/silccore/silcbufutil.[ch] new function;
8598 silc_buffer_realloc.
8600 * Moved generic packet sending/encryption functions to
8601 lib/silccore/silcpacket.[ch] from client and server. Some
8602 rewriting of the functions.
8604 * Moved all generic packet reception/decryption functions to
8605 lib/silccore/silcpacket.[ch] from client and server. The
8606 packet processing is now much cleaner in both client and server.
8607 These were major changes in both client and server.
8609 * Created many common functions in server to do packet sending.
8610 Previously code were duplicated a lot, this has been removed
8613 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8615 * Rewrote major parts of the ID cache system. Don't know
8616 whether it is better now or not but at least the API is more
8619 * Major rewrite on ID cache stuff on client because of the ID
8620 cache API changes. Added idlist.c to client.
8622 * Also major rewrite on ID cache stuff on server as well.
8623 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8624 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8625 in hand, instead they are all put into the ID cache system now.
8626 All server_idlist_* routines uses ID cache now instead of
8627 traversing its own lists (those lists does not exist anymore).
8628 SilcIDList though still exists. Also, SilcXXXEntry's are
8631 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8633 * Finally made the SKE implementation compliant to the protocol
8634 specification. All mp integers are now binary encoded as
8635 opposed being HEX encoded.
8637 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8640 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8641 functions: silc_[encode/decode]_pem. Also added function
8642 silc_encode_pem_file to PEM encode with newlines ('\n') for
8645 * SILC public keys are now encoded either PEM or binary. Same
8646 option is for private keys as well. By default private keys
8647 are binary encoded and public keys PEM encoded. Silly HEX
8648 encoding were removed.
8650 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8651 function to create fingerprints.
8653 * Fixed a bug in SHA1; does not change the original data anymore.
8655 * Partly implemented INFO command on client and server side.
8656 Fixed CLEAR command. Changes to SERVER command; show current
8657 server(s) when giving command without arguments. Added
8658 VERSION command to client.
8660 * Added check to server that unregistered connections cannot
8661 execute commands (unless it is specificly allowed).
8663 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8665 * Fixed screen refresh.
8667 * Fixed channel joining bug from client. On some circumstances
8668 client tried to join to a channel it had already joined.
8670 * Added public key verification process into client's protocol.c.
8671 The client now verifies the public key from user and saves
8672 it into ~./silc/serverkeys/ directory.
8674 Added into: clientutil.[ch]: silc_client_verify_server_key.
8676 * Changed SKE protocol's silc_ske_initiator_finish function
8677 to accept callback function that verifies the received public
8678 key. Removed old silc_ske_verify_public_key function.
8680 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8682 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8683 silc_pkcs_private_key[_data]_set.
8685 * Made the password and public authentication more cleaner in
8686 server's protocol.c.
8688 * Removed historic and obsolete protocol `channel_auth' from
8689 both client and server.
8691 * Removed wrong way of sending command status messages from
8692 server to client in server's command.c. The old way violated
8693 protocol specification.
8695 Changes to silccore/silccommand.[ch]: removed
8696 silc_command_encode_status_payload -> not needed anymore,
8697 changed silc_command_encode_payload_va to accept extra
8698 argument on variable argument list. The argument type must
8699 now be provided to the function. Also, added new function:
8700 silc_command_encode_reply_payload_va which is same as
8701 normal command_encode_payload_va except command status type
8702 is provided as extra argument.
8704 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8706 * Added ~./silc directory handling. The directory includes the
8707 public and private keys for the client.
8709 Added silc_client_check_silc_dir, silc_client_create_identifier
8710 and silc_client_load_keys.
8712 * Implemented SILC protocol compliant public key. Added public
8713 and private key saving to and loading from files.
8715 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8716 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8717 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8718 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8719 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8721 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8722 silc_pkcs_load_[public/private]_key.
8724 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8726 * Added silc_server_get_route (route.[ch]) to get connection
8727 data for the fastest route for given ID.
8729 * Implemented INVITE command on client and server. The command
8730 were re-defined in the SILC Protocol Specification and the
8731 implementation now complies with the specification.
8733 * Implemented PING command on client and server.
8735 * Implemented NAMES command on client and server. The server side
8736 supports currently only normal server not router server yet.
8737 Some changes to NAMES definition in SILC protocol specification.
8739 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8741 * Implemented LEAVE command on client and server.
8743 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8744 again. This change was made to the protocol as well. Server
8745 should not violate the protocol specification anymore.
8747 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8749 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8750 was tested. SOCKS4 was not but should work anyway.
