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

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

73 command reply from router, on normal server. Otherwise
74 joinig +a channels from normal server is not possible.
75 Affected file silcd/command.c.
77 * Fixed a bug in TOPIC_SET notify handling. The notifier
78 may be other than client too, like server or channel.

80 notify. Affected file silcd/packet_recieve.c.
82 * Removed some (unnecessary) debug printing from
83 lib/silccore/silcid.c and lib/silccore/silcargument.c.
85 * Do not force CMODE_CHANGE when server is announcing new
88 Router announces stuff only after server reannounces channel
89 after CHANNEL_CHANGE notify.
91 These fixes optimizes the announcing procedure, and perhaps
92 fixes some problems too. Affected file silcd/packet_receive.c.
94 * Fixed SERVER_SIGNOFF sending to local clients. It was
95 totally broken and sent the notify to all local clients,
96 instead of only to those that was on same channel as the
97 signing off clients. Affected file silcd/server_util.c.
99 * Added -D option to server. It can be used to give debug
100 level. The levels are from 0 - 99, and are predefined for
101 smooth server debugging. (see silcd.c for the predefined
102 levels). Affected file silcd/server.c.
104 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

738 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
739 specs and code. Protocol TODO #19. Affected files are
740 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
741 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
743 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added STATS command to the protocol after all, to return
746 various statistical information about the network. It can
747 be used by clients to retrieve statistical information, and
748 servers may use it to to fetch cell and network wide
749 statistics from router. Updated the protocol specs and
750 implemented it to the server. Protocol TODO #16.
751 Affected files are lib/silccore/silccommand, silcd/command.[ch],
752 silcd/command_reply.[ch].
754 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
756 * The LIST command reply in client libary now adds new channel
757 entry if the returned channel doesn't exist yet in cache,
758 and returns the channel entry to the application in the
759 command_reply client operation. Affected file is
760 lib/silcclient/command_reply.c.
762 * Changed the channel message payload's MAC generation to
763 include the IV in the MAC as well. This way all relevant
764 parts of the channel message payload are authenticated also
765 with the channel message MAC (and not only by packet MAC).
766 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
767 Affected file is lib/silccore/silcchannel.c.
769 * Fixed the SKE to save the remote version, since the
770 silc_ske_parse_version mistakenly checked wrong version,
771 after it replaced the start payload. Affected files are
772 lib/silcske/silcske.[ch].
774 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
777 string utility functions. Added there also new functions
778 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
779 Affected files lib/silcutil/silcstrutil.[ch].
781 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
782 files are lib/silcutil/silcstrutil.[ch].
784 * Defined that the security property fields in SKE SHOULD be
785 UTF-8 encoded, defined that version string MUST be US-ASCII
786 encoded, defined that passphrases sent in connection
787 authentication protocol MUST be UTF-8 encoded. Implemented
788 these to the client and server. Defined also that other
789 passphrases sent in the protocol MUST be UTF-8 encoded.
790 Affected files are lib/silcske/silcske.c,
791 lib/silcclient/protocol.c, silcd/protocol.c,
792 silcd/serverconfig.c, and lib/silccore/silcauth.c.
794 * Changed the silc_client_close_connection interface to not
795 need the SilcSocketConnection which should not be visible
796 to application. Affected files are lib/silcclient/client.c
797 and lib/silcclient/silcclient.h.
799 * Rewrote the text for Private Message Key Payload in the
800 protocol specification. Protocol TODO #11.
802 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Upgraded the protocol version to 1.1, updated protocol specs
807 * Added the nickname as new argument to NICK_CHANGE notify and
808 added it to protocol specs and implemented it to client and
809 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
810 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
811 lib/silcclient/client_notify.c.

814 it to protocol specs and implemented it to client and server.
815 Protocol TODO #13. Affected files are silcd/command.c,
816 silcd/packet_receive.c, packet_send.[ch],
817 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
818 The killer's client entry is now returned to application in
819 the `notify' client operation.
821 * Fixed the Max Argument fields that had too large value set
822 in the protocol specs. Protocol TODO #14.
824 * Added the LEAVE command reply to return the ID of parted
825 channel. Updated protocol specs and implemented it to the
826 client and server. Protocol TODO #15. Affected files are
827 silcd/command.c, lib/silcclient/command_reply.c. The channel
828 entry is now returned to application in the `command_reply'
831 * Rewrote the version SKE version checking in client libary
832 and in server to use the silc_parse_version_string. Affected
833 files are lib/silcclient/protocol.c, silcd/protocol.c.
835 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
836 commands that was missing it, and updated protocol specs and
837 the server implementation. Protocol TODO #10. The affected
838 file is silcd/command.c.
840 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
841 generic reply to a generic request (REQUEST flag), and
842 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
843 way. A draft-riikonen-silc-flags-payloads-00.txt is written
844 to define the payload for DATA flag. Added the flags to
845 the implementation. Protocol TODO #9. Affected file is
846 lib/silccore/silcchannel.h.
848 Changed the client library to return the message length
849 to application as well in the channel_message and private_message
850 client operations. Affected files are
851 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
852 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
853 and lib/silcclient/client_ops_example.c.
855 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
856 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
857 the channel. Updated protocol specs and impelemented this
858 to client and server. Protocol TODO #6. Affected files are
859 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
860 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
862 Added new options m and M to CMODE command in Irssi SILC
863 client to set these modes.
865 * Deprecated all administrative commands from SILC protocol
866 since they are highly implementation specific commands.
867 Updated protocol specs. Moved the old commands in
868 implementations to private range of command types. Affected
869 files are silcd/command.c, lib/silcclient/command.c and
870 lib/silcclient/command_reply.c. Protocol TODO #8.
872 * Fixed a bug in server where sending unknown command crashes
873 the server. Affected file silcd/command.c.
875 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Added SILC_PROTOCOLVERSION macro to check protocol version
878 of a socket connection. The affected file is
879 lib/silcutil/silcsockconn.h.
881 * Added better error logging in rekey protocol. Affected file
884 * Do not check public key types in SKE during rekey. Affected
885 file lib/silcske/payload.c.
887 * Fixed the rekey protocol with PFS, which was totally broken.
888 Affected file silcd/protocol.c.
890 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Some client implementations quit network by doing first LEAVE
893 and then immediately SIGNOFF (like Bombyx). We now do check
894 after a short time after LEAVE notify and check whether the
895 client is still valid after LEAVE, and if not we remove it from
896 cache. Affected file is lib/silcclient/client_notify.c.
898 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
900 * Merged version 1.1.4 of zlib. Even if it not currently in use,
901 it's good not to have security holes here.
903 * Fixed a negative refcount situtuation for the config context.
904 Affected file is silcd/serverconfig.c.
906 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
908 * ROBOdoc documented lib/silcutil/silcutil.h.
910 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
912 * Optimized even more the SilcPacketContext structure. Now
913 totally saved 16 bytes of memory per context after optimization.
914 Affected files are lib/silccore/silcpacket.[ch].
916 * Made strict checks for valid SILC IDs. Affected file is
917 lib/silccore/silcid.c.
919 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
921 * Changed the object argument for silc_cipher_register,
922 silc_hash_register, silc_hmac_register and silc_pkcs_register
923 to const. Affected files are lib/silccrypt/silccipher.[ch],
924 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
926 * Changed the silc_get_username and silc_get_real_name to
927 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
929 * Fixed the Irssi SILC Client to use the silc_get_username and
930 silc_get_real_name insted of glib routines since the glib
931 routines only corrupt stack. Fixes the Irssi SILC to work in
932 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
934 * Fixed the Irssi to not use g_get_home_dir since it crashes
935 or returns garbage on cygwin and corrupts stack. Added function
936 get_home_dir to Irssi routines. Affected files are
937 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
939 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Made some structure optimizations. SFTP memory FS MemFSEntry
942 entry structure. Optimized SilcTask structure. Optimized
943 SilcPacketContext structure.
945 Affected files lib/silcsftp/sftp_fs_memory.c,
946 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
948 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
950 * And yet again reverted back the config thing since Johnny
951 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
954 * Fixed memory leaks from config object. Affected files are
955 silcd/serverconfig.[ch].
957 * Added support for adding new connections to the server in rehash.
958 After rehash they take effect.
960 Added support for changing the maximum allowed connections in
961 rehash. The number can grow but going smaller is not supported.
963 Added function silc_server_num_sockets_by_remote to the
964 silcd/server_util.[ch].
966 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
968 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
970 * Added preliminary checking during config parsing for a valid
971 public/private key and removed further checks in the code.
972 Affected files are silcd/serverconfig.[ch], server.c.
974 * Moved functions silc_server_drop() and silc_server_daemonise()
975 from server.c to silcd.c since they are stricly related to
976 the application activity.
978 * Reverted a small part of the automatic ref/unref since
979 it caused a double unref in some situations. Affected
980 files are silcd/silcd.[ch], server.c, serverconfig.c.
982 * Added some .cvsignore files in the lib directory.
984 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Fixed silc_net_gethostbyaddr to correctly resolve by
987 address. Affected file lib/silcutil/silcnet.c.
989 * Fixed the notify relaying to client. The HMAC to be used
990 with relayed packets ws wrong and caused decryption failure
991 at the client end. Affected file is silcd/packet_receive.c.
993 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Created new branch silc_protocol_1_0_branch.
997 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
999 * Changed the silc_server_config_* routines to be SilcServer
1000 independent. They are now officially application specific code
1001 and not part of generic server implementation. Affected files
1002 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1004 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Added automatic referencing of config context in the
1007 silc_server_config_alloc, and automatic unreferencing in the
1008 silc_server_config_destroy. Affected files are
1009 silcd/serverconfig.[ch], silcd/silcd.c.
1011 * Fixed the silc_log_quick handling in the logging routines.
1012 It didn't log quickly when it was TRUE. Affected file is
1013 lib/silcutil/silclog.c. Also the flush delay was set even
1014 if it was 0 in config file. Affected file is
1015 silcd/serverconfig.c.
1017 * Added support for changing key pair of the server in rehash.
1018 Affected file silcd/server.c.
1020 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1023 too early, before getting the channel entry. Affected file
1024 is silcd/packet_receive.c.
1026 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1028 * Added functions silc_server_config_[ref/unref], these are used
1029 to prevent that the config object is destroyed.
1031 No longer directly affect global variables silc_log_quick and
1032 silc_log_delay, they are first cached inside the config object
1033 and then applied with silc_server_config_setlogfiles().
1035 silc_server_config_set_defaults() is now internal to
1036 serverconfig.c, there are no reasons to show this internal stuff
1039 Affected files are silcd/serverconfig.[ch].
1041 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1042 fprintf's to stderr, since some code may be executed again after
1043 the server went into the background. Affected files are
1046 * Added rehash support. Added function silc_server_rehash() that
1047 will perform all the basic tasks of the rehashing procedure.
1049 * Added command line option `-x, --hexdump'. This will enable the
1050 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1051 The option `--hexdump' implies `--debug'.
1053 * Fixed a bad bug in the logging APIs (silcutil library) where
1054 the application would crash after calling silc_log_reset_all().
1056 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1058 * Fixed the KICKED notify handling in client library to
1059 correctly remove the channel and all entries from the
1060 channel when I was kicked. This bug crashed the client.
1062 Fixed yet another but in KICKED notify handling to remove
1063 the kicked client correctly from the channel.
1065 Affected file is lib/silcclient/client_notify.c.
1067 * Fixed a minor bug in looking up correct client entry
1068 in KICKED notify in server. Affected file is
1069 silcd/packet_receive.c.
1071 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1072 sources correctly to distribution. Fixes --with-gmp option.
1074 * Removed the manual rehashing from ID Cache, and changed it
1075 to use the SILC Hash Table's auto rehash feature. Affected
1076 file is lib/silccore/silcidcache.c.
1078 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1080 * Fixed a bug in the silc_client_nickname_format function that
1081 handles the multiple same nickname formatting. Two clients
1082 with same nickname caused problems after the first one left
1083 and rejoined. It didn't format the nickname correctly.
1084 Affected file is lib/silcclient/idlist.c.
1086 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1088 * Don't change the topic if olod topic is same as new one.
1089 Affected file is silcd/packet_receive.c.
1091 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1093 * Added cross-reference support to the SILC Documentation
1094 generator. All types across all HTML files are now cross-
1095 referenced. Affected files util/robodoc/generator.c and
1096 scripts/silcdoc/silcdoc.
1098 * Added file lib/silcutil/silctypes.h to include all the
1099 arithmetic type definitions and some macros. Removed
1100 includes/bitmove.h and moved macros to silctypes.h.
1102 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1106 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1108 * Added `type' argument to silc_id_payload_parse_id function which
1109 now returns the type of the ID to the sent pointer. Affected
1110 file is lib/silccore/silcid.[ch].
1112 * Added check for CMODE_CHANGE notify type that mode change is
1113 allowed by the sender. Affected file silcd/packet_receive.c.
1115 * Added check for CUMODE_CHANGE notify type that mode change is
1116 allowed by the sender. Affected file silcd/packet_receive.c.
1117 Added the ID type as CUMODE_CHANGE notify type as argument
1118 to the `notify' client operation. Affected files are
1119 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1121 * Added function silc_client_add_server to the client library.
1122 Added support for resolving also channel and server info when
1123 received unknown entity in notify packet. Affected files are
1124 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1126 * Added function silc_command_get_status to return the command
1127 status from the command reply's argument payload. Affected files
1128 are lib/silccore/silccommand.[ch].
1130 * Added check for KICKED notify type that the kicking is
1131 allowed by the client. Affected file silcd/packet_receive.c.
1133 * Created function silc_get_input which can be used to get input
1134 (echo on or off) from user on command line. Affected files are
1135 lib/silcutil/silcutil.[ch].
1137 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1139 * Optimized silc_server_packet_relay_to_channel function.
1140 Added new function silc_channel_message_payload_encrypt which
1141 can be called directly if channel message payload needs to
1142 be encrypted and is already encoded (no need to call _encode
1143 function). Packet relaying is now done by router without any
1144 extra memory allocations. Affected files are
1145 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1146 silcd/packet_send.c.
1148 * Fixed the INVITE notify handling. It took wrong arguments
1149 as invite list and invite delete. Affected file is
1150 silcd/packet_receive.c.
1152 * Added check for TOPIC_SET notify type that the topic change is
1153 allowed by the client. Affected file silcd/packet_receive.c.
1155 * Added check for INVITE notify type that inviting is allowed by
1156 the client. Affected file silcd/packet_receive.c.
1158 * Changed the silc_server_client_on_channel to return the
1159 SilcChannelClientEntry as well. Moved the function
1160 silc_server_check_cmode_rights to server_util.[ch].
1161 Affected files are silcd/server_util.[ch], silcd/command.c.
1163 * Added function silc_server_check_umode_rights to check whether
1164 changing client's user mode is allowed. Added check for
1165 UMODE_CHANGE notify type that the umode change is allowed
1166 by the client. Affected files are silcd/server_util.[ch],
1167 silcd/packet_receive.c and silcd/command.c.
1169 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1171 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1172 ID length. It ignored that ID can be IPv6 based as well.
1173 Affected file lib/silccore/silcpacket.h.
1175 * Fixed the silc_id_id2str and silc_id_str2id to take the
1176 IPv6 address offset's into consideration. Affecte file is
1177 lib/silccore/silcid.c.
1179 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1181 * Fixed the internal Unix scheduler functions to check for
1182 NULL context they may receive. The affected file is
1183 lib/silcutil/unix/silcunixschedule.c.
1185 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1187 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1188 can specify different directory with --home command line
1189 parameter. Affected files irssi/src/silc/core/client_ops.c,
1192 * SILC-specific commands aren't now executed if the active server
1193 isn't of SILC-type, so there won't be problems with having
1194 IRC and SILC protocol support in same client. Affected files
1195 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1198 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Improved the signal support in SILC Schedule. Added new
1201 function silc_schedule_signal_call which is used by application
1202 to mark a signal to be called. It is now safe to perform
1203 any kind of tasks in signal callbacks since it is guaranteed
1204 that the application specified signal callback is called
1205 after the signal is over. Affected files are
1206 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1208 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Added `name' field to SilcChannelPrivateKey to represent
1211 application given name for the key. Moved also the context from
1212 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1213 Added the `name' argument also to the function
1214 silc_client_add_channel_private_key.
1216 Added function silc_client_current_channel_private_key to set the
1217 current channel private key in use.
1219 Added "change" command to KEY command which can be used to change
1220 the current channel private key. Bound the command also to
1221 alt+K (Alt+Shift+k).
1223 Also affected files lib/silcclient/client_channel.c,
1224 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1226 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1228 * Added silc_rng_get_byte_fast function in to the
1229 lib/silccrypt/silcrng.[ch].
1231 * Changed the interface of silc_packet_assemble and the
1232 silc_packet_send_prepare. If silc_packet_assmble is now
1233 called the application does not call silc_packet_send_prepare
1234 because the library will call it automatically. These
1235 interfaces now also return a reference to the outgoing buffer
1236 which includes the assembled packet, which the application can
1237 use to encrypt the packet.
1239 Affected files are lib/silccore/silcpacket.[ch],
1240 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1241 silcd/packet_send.c, server_backup.c and packet_receive.c.
1243 * Fixed a packet sending bug on very high load, where outgoing
1244 packet queue wasn't handled correctly and packets got corrupted.
1245 Affected files are lib/silcutil/*/silc*sockconn.c,
1246 lib/silcclient/client.c and silcd/server.c.
1248 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1250 * Added macro SILC_PACKET_DATALEN which can be used during
1251 packet assembling to check whether the data to be added to
1252 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1253 len is truncated until it fits it.
1255 Added checks for maximum length of channel message payload and
1256 private message payload also.
1258 Added checks for maximum packet length in server and in
1261 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1262 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1263 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1264 lib/silcclient/client_prvmsg.c.
1266 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Added silc_server_packet_queue_purge call to the
1269 silc_server_disconnect_remote to assure that all data in the
1270 queue before disconnecting is sent to the network. Affected
1271 file silcd/server.c.
1273 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Added the deleting of server's own ID cache entry to the
1276 silc_server_free function. Free also everything else that
1277 has been allocated in silc_server_init. The affected file
1280 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1282 * Added functions silc_parse_version_string, silc_version_to_num,
1283 and silc_ske_parse_version to parse SILC protocol style version
1284 strings. Affected files lib/silcutil/silcutil.[ch] and
1285 lib/silcske/silcske.[ch].
1287 * Added new configuration params: version_protocol, version_software
1288 and version_software_vendor to specify what version the remote
1289 host must at least be to be able to connect to server. The vendor
1290 string can be regex matched too. Added new function
1291 silc_server_connection_allowed to check maximum number of allowed
1292 connections, and allowed versions for incoming connections.
1293 Affected files are silcd/server.c, server_util.[ch] and
1296 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1298 * Added preliminary support for signals in scheduler. The
1299 signals we care about are now blocked always when the scheduler
1300 is locked. This way we can synchronise the use of signal with
1301 scheduler. It is guaranteed that when signal occurs the scheduler
1302 is not locked, and thus new tasks can be safely added to the
1305 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1306 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1307 Added new platform specific routines
1308 silc_schedule_internal_signals_[un]block and
1309 silc_schedule_internal_signal_[un]register.
1311 Added new functions to SILC Schedule API:
1312 silc_schedule_signal_[un]register. Each signal that application
1313 is going to use should be registered to the scheduler.
1315 Affected files are lib/silcutil/silcschedule.[ch],
1316 lib/silcutil/*/silc*schedule.c.
1318 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1320 * Check for unauthenticated client and server in the
1321 silc_server_new_client and silc_server_new_server functions.
1322 Affected file silcd/packet_receive.c.
1324 * Added function silc_string_is_ascii to check whether given
1325 string is 7-bit ASCII string. Affected files are
1326 lib/silcutil/silcutil.[ch].
1328 * Added function silc_id_is_valid_server_id into the
1329 silcd/serverid.c and added checking for valid Server ID's in
1330 silc_server_new_server. The Server ID must always be based
1331 on the server's public IP address.
1333 * Added logging of DISCONNECT packet message in the server.
1334 Affected file silcd/server.c.
1336 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1338 * Changed all library interfaces that use Global RNG to also
1339 accept SilcRng as argument. Affected files are
1340 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1341 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1342 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1343 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1344 lib/silccrypt/rsa.c.
1346 * Added function silc_pkcs_generate_key to the
1347 lib/silccrypt/silcpkcs.[ch] for applications so that they
1348 don't need to do pkcs->pkcs->init calls anymore.
1350 * Remove SilcSocketConnection from the SFTP API since it really
1351 wasn't needed there. The application has the information
1352 saved in its contexts anyway and the SFTP layer doesn't need
1353 know about it. Affected files lib/silcsft/silcsftp.h and
1354 lib/silcsftp/sftp_[server/client].c.
1356 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1357 The SilcSimContext is not SilcSim.
1359 * Fixed possible buffer overflows in silc_id_render in the
1360 lib/silcutil/silcutil.c.
1362 * On EPOC the global crypto module lists are not used at all
1363 in the crypto library. Added support for using the constant
1364 algorithm list on EPOC. Affected files are
1365 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1368 * Fixed the handling of third parameter of KICKED notify, since
1369 it was mistakenly updated to SILC Protocol 1.0 even though it
1370 is to be included in 1.1. Since it is not in 1.0 it is not
1371 mandatory, and this fix now handles it only if it is provided,
1372 and it is not error if it is not provided. Affected file
1373 lib/silcclient/client_notify.c.
1375 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1377 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1378 client. Affected file irssi/src/silc/core/client_ops.c.
1380 * Merged with Irssi 0.8.4 from irssi.org CVS.
1382 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Check for valid socket connection in client entries before
1385 sending any messages. Fixes a crash, but doesn't fix some
1386 other underlaying bug that is lurking there. Affected
1387 file silcd/packet_send.c.
1389 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1391 * $usermode, $cumode and $cumode_space expandos shouldn't do
1392 anything with non-SILC server records. Affected file
1393 irssi/src/silc/core/silc-expandos.c
1395 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1397 * Fixed the silc_net_check_[host/local]_by_sock to support
1398 IPv6 bound sockets as well. Now they can return IPv6 addresses
1399 as well. Affected file lib/silcutil/silcnet.c.
1401 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1402 Affected lib/silcutil/unix/silcunixnet.c.
1404 * Fixed ID rendering (at least on some platforms, not NetBSD)
1405 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1407 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1409 * Added silc_hash_public_key and silc_hash_public_key_compare
1410 functions to be used with SilcHashTable. They can be used to
1411 hash public keys and compare public keys in hash table. Affected
1412 file lib/silcutil/silcutil.[ch].
1414 * Added support for specifying multiple public keys for Client
1415 connection section in server configuration file. This makes it
1416 possible to accept multiple public keys from same host, or to
1417 make a section that accepts any incoming host, and have the
1418 accepted public keys listed in the section.
1420 Added functions silc_sever_[find/get]_public_key, added the
1421 support for this actually to all connection sections but only
1422 the Client section is currently allowed to specify multiple
1425 Affected files are silcd/server.c, server_internal.h,
1426 command.c, protocol.c, server_util.[ch], packet_receive.c.
1428 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1430 * Merged Irssi 0.8.2 from irssi.org CVS.
1432 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1434 * If silc_debug is TRUE, also output standard logging messages
1435 to stderr with the debug output.
1437 Made silc_log_reset_all() flushing all channels before returning.
1438 Also fixed some documentation typos.
1440 Affected files are lib/silcutil/silclog.[ch].
1442 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed the server to check correctly the amount of connections
1445 from single host, by checking also the type of the connection.
1446 Fixed also the comparison of number of connections and number
1447 of allowed connections. Affected files are silcd/server.c,
1450 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1452 * Fixed the USERS command reply to save the user's mode on the
1453 channel as well. Fixed JOIN command reply to check whether a
1454 client is on channel already and not join it twice. Affected
1455 file lib/silcclient/command_reply.c.
1457 * Added new file silc-expandos.c into irssi/silc/core/ to return
1458 various stuff for various signal for the statusbar etc. updating.
1459 Now Irssi SILC client prints channel user modes etc. on the
1462 * The user mode (like server/router operator changes) is now shown
1463 on the Irssi SILC client's statusbar. The affected files are
1464 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1466 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1469 to SILC_SCHEDULE_[UN]LOCK macros.
1471 * Added more error printing to logs in server code. Affected
1472 files silcd/server.c and silcd/protocol.c.
1474 * Fixed -S option parsing in Irssi SILC Client. Affected file
1475 irssi/src/silc/core/silc-core.c.
1477 * Added silc_buffer_alloc_size function. Affected file is
1478 lib/silcutil/silcbuffer.h.
1480 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1482 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1483 constants. Affected files in
1484 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1487 * Changed the internal SFTP Memory FS table to const. Affected
1488 file lib/silcsftp/sftp_fs_memory.c.
1490 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1492 * Fixed the buffer formatting and unformatting routines to
1493 check the size of 64 bits types with sizeof(). Affected
1494 file is lib/silcutil/silcbuffmt.c.
1496 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1498 * Removed 0.6.x backwards support.
1500 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1502 * Changed all integer type names:
1503 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1504 to avoid collisions with other libraries using same type names
1507 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1509 * Added `prefer_ipv6' argument to the functions
1510 silc_net_gethostbyname[_async]. If it is TRUE it will return
1511 IPv6 address over IPv4. If FALSE IPv4 address is returned
1512 even if IPv6 address was found. Affected files
1513 lib/silcutil/silcnet.[ch].
1515 * Added support silc_net_create_connection[_async] to fallback
1516 to IPv4 address if IPv6 address could not be used (like if
1517 it doesn't work on a specific system). Affected file in
1518 lib/silcutil/unix/silcunixnet.c.
1520 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1522 * Added silc_schedule_reinit function to do the enlarging
1523 of the max tasks handling capabilities of the scheduler.
1524 Affected files lib/silcutil/silcschedule.[ch].
1526 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1528 * Added automatic extern "C" { ... } for C++ compilers so the
1529 application does not need to define them. Affected file
1530 includes/silcincludes.h.
1532 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1533 old name went against naming convention. Applications now
1534 include "silcclient.h" instead of "clientlibincludes.h".
1535 Removed includes/clientlibincludes.h, it is redundant now.
1537 * Renamed includes/version.h to silcversion.h.
1539 * Added really preliminary support for OS/2 into the util
1540 library. Only thread & mutex API is implemented, others
1541 are still to be implemented. Created the lib/silcutil/os2/
1542 directory. Created also file includes/silcos2.h.
1544 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1546 * Added preliminary BeOS support into the util library.
1547 Created lib/silcutil/beos/, and implemented all the needed

1560 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1563 * Fixed the silcdoc document generator to correct generate
1564 docs from all kinds of filenames. Affected files are
1565 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1567 * ROBOdoc documented lib/silcutil/silcmemory.h.
1568 Added also new function silc_memdup.

1573 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1575 * Added `user_count' to the SilcChannelEntry which now tells the
1576 number of users on the channel. The user count is now saved
1577 in normal server of global channels as well. Affected files
1578 silcd/server.c, idlist.h, packet_receive.c and command.c.
1580 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1581 include file utility functions.
1583 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1584 instead of calling directly OS routines.
1586 * Fixed NICK change printing in Irssi SILC Client. Fixed
1587 KICKED notify printing in Irssi SILC Client. Affected file
1588 irssi/src/silc/core/client_ops.c.

1597 the SKE interface a bit.
1599 * Fixed padding problem in PKCS#1. The padding was not actually
1600 random since the random number generator was used incorrectly.
1601 This security bug affects only when encrypting with PKCS#1, and
1602 it is not currently used at all in SILC. SILC only use signing
1603 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1660 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1662 * Fixed command line parameter handling. All SILC initialization
1663 is now done in silc_core_init() which also fixes autoconnecting
1666 Affected files irssi/src/silc/core/silc-core.c,
1667 irssi/src/fe-text/silc.c.
1669 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1671 * Added new configuration options and blocks:
1672 keepalive_secs, reconnect_count, reconnect_interval,
1673 reconnect_interval_max, reconnect_keep_trying and
1674 require_reverser_lookup. Added ConnectionParam block, and
1675 implemented the connection parameters when connecting as
1676 initiator and when accepting connections as responder.

1688 the connection configuration object from the SilcServerConnection
1689 object instead of finding it during the connecting phase.
1690 Added the configuration object to SilcServerConnection struct.
1691 Affected files silcd/server_internal.h, server.c.
1693 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1695 * Add the client on channel after it was resolved at the
1696 channel message receiving, and it was not already on the
1697 channel. Affected file lib/silcclient/client_channel.c.
1699 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1715 authentication to be set at the same time.
1717 Added `prefer_passphrase_auth' setting in config file which
1718 can be used to set to prefer passwd auth if both passwd and
1719 public key is set. If not set, public key is preferred.
1720 This has effect only when being initiator (responder will try
1723 Added support for authentication with passphrase and public key
1724 at the same time. The passphrase is tried first always since
1725 it is faster to check.
1727 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1729 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1731 * Merged the new SILC Config library, with the server parsing

1775 * Fixed the file transfer's key agreement payload to include
1776 zero port also if the hostname is NULL because it could not
1779 Call file transfer monitor callback now also if error occurs
1780 during key agreement protocol.
1782 Changed the silc_client_file_send interface to return the
1783 SilcClientFileError instead of session id. The session ID
1784 is returned into pointer provided as argument.
1786 Check that the file exists locally before sending the
1787 file transfer request at all.
1789 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1791 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1801 file lib/silcutil/silclog.c.
1803 * Fixed the channel message payload decryption in the function
1804 silc_channel_message_payload_decrypt to not modify the original
1805 buffer before it is verified that the message decrypted
1806 correctly. Otherwise, next time it is called with correct
1807 channel key it won't encrypt since the payload is corrupted.
1808 Affected file lib/silccore/silcchannel.c.
1810 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1823 the table with foreach callback. The current entry may
1824 become invalid in the callback but it was referenced after
1825 the callback returned.
1827 Do not allow auto rehashing of hash table during the
1828 silc_hash_table_foreach operation, for same reasons as it is
1829 not allowed for SilcHashTableList. Affected files are
1830 lib/silcutil/silchashtable.[ch].
1832 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1838 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed private message handling. It used some old code that
1841 caused the client to crash. Affecte file is
1842 lib/silcclient/client_prvmsg.c.
1844 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * Added function silc_client_add_channel,
1847 silc_client_replace_channel_id, and removed functions
1848 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1849 from client library.
1851 * Added cross reference of the joined channels to the
1852 SilcClientEntry, and changed the SilcChannelEntry's
1853 users list to SilcHashTable. The affected files are
1854 lib/silcclient/idlist.[ch].
1856 * Fixed a bug in hash table tarversing. While the hash table
1857 is traversed with SilcHashTableList the table must not be
1858 rehashed. It is now guaranteed that auto rehashable tables
1859 are not rehashed while tarversing the list. Also defined that
1860 silc_hash_table_rehash must not be called while tarversing
1861 the table. Added function silc_hash_table_list_reset that must
1862 be called after the tarversing is over. The affected files are
1863 lib/silcutil/silchashtable.[ch].
1865 * Changed all hash table traversing to call the new
1866 silc_hash_table_list_reset in server and in client library.
1868 * Added function silc_client_on_channel to return the
1869 SilcChannelUser entry if the specified client entry is joined
1870 on the specified channel. This is exported to application as
1871 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1873 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed founder regaining problem with JOIN command on normal
1876 server. The notify for mode change must be sent always and
1877 not only if !cmd->pending. Affected file silcd/command.c.
1879 * Fixed the WHOWAS command's reply sending to support the
1880 lists correctly. Affected file silcd/command.c.
1882 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * When sending JOIN command to router for processing the
1885 sender's old command identifier was not saved back to the
1886 sender's command context, fixed now. The affected file is
1889 * Create the key in JOIN command of the router did not return
1890 the channel key, added check for this. Affected file is
1893 * Fixed a channel ID update bug in JOIN command reply. Do
1894 not directly upgrade the ID but call the function
1895 silc_idlist_replace_channel_id if the ID was changed.
1896 Affected file silcd/command_reply.c.
1898 * Fixed memory leaks from command calling if it would fail.
1899 Affected file silcd/command.c.

1911 * Removed TRQ from lib/trq, not needed anymore.
1913 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1914 with server connections. Later this will be configurable
1915 in config file after new config file is done. Affected file
1918 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1920 * Fixed a crash in server related to channel announcements.
1921 Affected file silcd/server.c.
1923 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1925 * Fixed memory leaks in silc_server_create_new_channel*
1926 functions. Affected file silcd/server.c.
1928 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1929 which ID was changed. This way the router will send the
1930 user list for the channel again, and server won't be in
1931 desync in some rare circumstances. Affected file is
1932 silcd/packet_receive.c.
1934 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1949 file for application programmers to quickly start using
1950 the SilcClientOperation functions in their application.
1951 Updated the lib/silcclient/README as well to tell about this
1952 nice file made available.
1954 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1956 * Call silc_server_remove_from_channels when removing client
1957 entry when NO_SUCH_CLIENT_ID was received. Affected file

1962 * Added server & router operator statistics updating. Affected
1963 file silcd/packet_receive.c and silcd/command.c.
1965 * Fixed the SERVER_SIGNOFF notify handling on normal server
1966 not to save the history information for clients. Same was
1967 fixed earlier in remove_clients_by_server function, but not
1968 here. Affected file silcd/packet_receive.c.
1970 * Raised the default connection-retry count from 4 to 7 in
1971 server. Affected file silcd/server.h.
1973 * Cancel any possible reconnect timeouts when we start the
1974 key exchange. Affected file silcd/server.c.

1981 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1983 * Fixed the NICK command to always give the unformatted
1984 nickname to the one giving the NICK command. If unformatted
1985 nickname is cached already it will be formatted and the
1986 local entry will always get the unformatted nickname.
1987 Affected file lib/silcclient/idlist.c.
1989 * Fixed some double frees from client library commands.
1990 Affected file is lib/silcclient/command.c.
1992 * Fixed CUMODE command in server to assure that no one can
1993 change founder's mode than the founder itself, there was a
1994 little bug. Affected file silcd/command.c.
1996 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1998 * Removed the SilcClientCommandDestructor from the client
1999 libary, it is not needed anymore. Affected files are
2000 lib/silcclient/silcapi.h, command[_reply].[ch],
2001 client_notify, idlist.c.
2003 * Fixed GETKEY command to first resolve client, and then
2004 resolve the server only if the client was not found, instead
2005 of resolving both at the same time. Affected file is
2006 lib/silcclient/command.c.
2008 * Added silc_client_start_key_exchange_cb and lookup the
2009 remote hostname and IP address before starting the key
2010 exchange with server. The affected file is
2011 lib/silcclient/client.c.
2013 * The server's public key is now saved using the IP address
2014 of the server and not the servername for the filename.
2015 The hostname public key filename is checked as an fall back
2016 method if the IP address based filename is not found.
2018 Fixed the GETKEY command to save the fetched server key
2019 in correct filename.
2021 Print the remote server's hostname now when new key is
2022 received during connection process. Affected file is
2023 irssi/src/silc/core/client_ops.c.
2025 * Return always our own public key to the client if it asks
2026 for it with GETKEY command. Affected file silcd/command.c.
2028 * Removed the use_auto_addr variable from default config
2029 file since it was in wrong section. Affected file is
2032 * Fixed TOPIC_CHANGE notification to not route it when it
2033 was sent using silc_server_send_notify_to_channel function.
2034 Affected file silcd/command.c.
2036 * Fixed silc_server_send_notify_kicked to send the kicker's
2037 Client ID also, it was missing. Affected files are
2038 silcd/command.c, silcd/packet_send.[ch].
2040 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Do not save client history information in SERVER_SIGNOFF.
2043 Fixes the bug in normal server that it does not detect
2044 the client becoming valid after the server becomes back
2045 online. Affected file silcd/server_util.c.
2047 * Added `sock_error' field into the SilcSocketConnection
2048 context. When error occurs during socket operation (read
2049 or write) the error is saved. Added also new function
2050 silc_socket_get_error to return human readable socket error
2051 message. Affected files are lib/silcutil/silcsockconn.[ch],
2052 lib/silcutil/unix/silcunixsockconn.c, and
2053 lib/silcutil/win32/silcwin32sockconn.c.
2055 * The server now prints the socket error message in the
2056 signoff for client. Affected file silcd/server.c.
2058 * Fixed the `created' channel information sending from router
2059 to server in JOIN command. Checks now whether the channel
2060 really was created or not and set it according that.
2062 Fixed the JOIN command to use the client entry's current
2063 ID during the joining procedure instead of the one it sent
2064 in the command (it is checked though), since it can change
2065 between the packet processing and command processing, and
2066 would just case unnecessary pain in the client end. Affected
2067 file silcd/command.c.
2069 * Fixed a channel key payload sending to use correct channel
2070 ID when the server was forced to change the channel's ID by
2071 router. Router sent the key payload with the old Channel ID.
2072 Affected file silcd/packet_receive.c.
2074 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2076 * Call silc_server_save_channel_key only if the key payload
2077 was provided in the JOIN command's command reply. Affected
2078 file silcd/command_reply.c.
2080 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2082 * Fixed silc_mp_sizeinbase to return the value correctly with
2083 MPI. Affected file lib/silcmath/mp_mpi.c.
2085 * Fixed the stop_server signal to correctly stop the scheduler
2086 and gracefully stop the server when SIGTERM or SIGINT signals
2087 are received. Affected file silcd/silcd.c.
2089 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2091 * Simple handling of TERM and HUP signals. Also added some log
2092 flushing call around. Affected file is
2095 * Fixed small bugs in silclog.c. Now buffering output will take
2096 effect after 10 seconds since startup: This will ensure that
2097 no important startup messages are lost. Also output redirection
2098 will preserve original format ([Date] [Type] message).
2099 Affected file is lib/silcutil/silclog.c.
2101 * Added two options to the config file, in the logging section:
2102 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2103 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2105 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2107 * Do not print the warning about log files not being initialized
2108 more than once to avoid excess logging. Affected file is
2109 lib/silcutil/silclog.c.
2111 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2112 the SIM copying in make install in Makefile.am.pre.
2114 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2116 * Rewritten silclog APIs. Globally interesting changes follows:
2117 silc_log_set_files() changed to silc_log_set_file().
2118 silc_log_set_callbacks() changed to silc_log_set_callback().
2119 ROBOdoc documented silclog header file.
2120 SilcLogCb now returns bool to wether inihibit the default
2121 handler or not (to keep the old behaviour return always TRUE).
2122 The new APIs should also fix the problem of the
2123 silcd_error.log file that was written in the current directory.
2126 Log files streams will remain opened after silc_log_set_file()
2127 call, means less CPU usage notably on high traffic servers.
2128 File streams are now full buffered, and flushed to the disk
2129 every 5 minutes, lesses HD activity and CPU usage.
2130 Messages can be redirected, allowing admins to configure
2131 one single logfile for all server messages.
2132 the silc_log_quick global variable to activate fast-logging.
2133 Affected files lib/silcutil/silclog.[ch]
2135 * Changed some code to conform new silclog APIs. Affected
2136 files are doc/example_silcd.conf.in, silcd/server.c
2137 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2140 * Fixed a memory leak that could occur in some situations.
2141 Affected file silcd/serverconfig.c.
2143 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2145 * Added the silc_client_del_client to remove the client from
2146 all channels as well. Affected file lib/silcclient/idlist.c.
2148 * Fixed the client library to correctly remove the client
2149 from all channels when the client entry is being destroyed.
2150 Affected file lib/silcclient/client_notify.c, command.c.
2152 * Added auto-nicking support to the client library. If the
2153 applicatio now sets client->nickname it will be sent to the
2154 server after connecting by the library. This way for example
2155 SILCNICK (or IRCNICK) environment variables will have effect
2156 and always change the nickname automatically to whatever
2157 it is wanted. Affected file lib/silcclient/client.[ch].
2159 * Renamed silc_server_command_bad_chars to the
2160 silc_server_name_bad_chars and moved it to the
2161 silcd/server_util.[ch]. Added also new function
2162 silc_server_name_modify_bad to return nickname that
2163 includes bad characters as new nickname without those
2164 bad characters. This check and modify is now used in
2165 silc_server_new_client when the username is initially set
2166 as nickname, so it must be checked to be valid nickname.
2167 Affected file silcd/packet_receive.c.
2169 * The nickname length is now taken from the packet for real
2170 and not trusted to strlen() since it clearly can return
2171 wrong length for nickname including bad characters. This
2172 also applies to channel names. Affected file silcd/command.c.
2174 * Removed the lib/silcsilm/modules directory. Modules are now
2175 compiled into the lib/silcsim. Fixed the copying of the
2176 modules to follow symbolic links in Makefile.am.pre.
2178 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2180 * Fixed silc_string_regexify list creation. Fixes bugs with
2181 BAN and INVITE commands in server. The affected file is
2182 lib/silcutil/unix/silcunixutil.c.
2184 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Removed the command destructor entirely from the server's
2187 command and command reply routines. It is not needed, and
2188 its usage was buggy and caused crashes. Affected files are
2189 silcd/command[_reply].[ch].
2191 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Cancel protocol and NULL sock->protocol if timeout
2194 occurred during protocol. Affected file silcd/server.c.
2196 * Cancel protocol timeouts always before calling the final
2197 callback, to assure that after final callback is called
2198 no other state will be called for the protocol anymore.
2199 Affected file silcd/protocol.c.
2201 * Print error log if incoming connection configuration could
2202 not be found. Affected file silcd/server.c.
2204 * Fixed JOIN command to correctly save the founder mode
2205 to the client on normal SILC server, when the channel
2206 was created by the router. Affected file silcd/command.c.
2208 * Fixed LIST command (hopefully) to send correct reply
2209 packets. Affected file silcd/command.c.
2211 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * The silc_packet_receive_process now returns FALSE if the
2214 read data was invalid packet, and TRUE if it was ok.
2216 The server now checks that if unauthenticated connection
2217 sends data and its processing fails the server will close
2218 the connection since it could be a malicious flooder.
2220 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2222 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Make sure the warning about error opening a log file is
2225 printed only once and not everytime it fails (produces
2226 too much useless log). Affected file lib/silcutil/silclog.c.
2228 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2230 * Made the silc_server_daemonise() function more readable.
2231 Affected file silcd/server.c.
2233 * Pid file is now optional, the user may comment it out from
2234 the config file. Removed define SILC_SERVER_PID_FILE, we
2235 don't need a default any longer. Affected file
2236 configure.in.pre, lib/Makefile.am.pre.
2238 * Make some use of the pid file. The server now dies at startup
2239 if it detects a valid pid file on his path. The server would
2240 die anyway in this circumstance, because of the bind() failure.
2241 Affected file silcd/silcd.c.
2243 * No longer compiling lib/dotconf.
2245 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Fixed JOIN command parsing not to crash. Affected file
2248 lib/silcclient/command.c.
2250 * Fied the NICK_CHANGE notify to add the new client entry
2251 even it is resolved. This removes an <[unknown]> nick
2252 thingy bug in the client. Affected file is
2253 lib/silcclient/client_notify.c.
2255 * Do not try to allocate 0 bytes (efence does not like it)
2256 in lib/silccore/silccomand.c when encoding payload.
2258 * Do not take IRCNICK as nickname in Irssi SILC client since
2259 it is not possible to set nickname before hand connecting
2260 the server (TODO has an entry about adding auto-nicking
2263 * Changed the silc_server_command_pending to check whether
2264 there already exists an pending entry with the specified
2265 command, command identifier and pending callback. This is
2266 to fix IDENTIFY and WHOIS related crashes that may register
2267 multiple pending commands with same identifier. Affected
2268 file silcd/command.c.
2270 * Fixed the server to reconnect to the router even if it
2271 was already reconnecting and EOF was received. This to
2272 fix a possibility that the server wouldn't ever try to
2273 auto-reconnect to the router. Affected file silcd/server.c.
2275 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Fixed the server's password authentication to use the
2278 length of the locally saved password, and not the one
2279 sent in the packet. Affected file silcd/protocol.c.
2281 * Fixed same password authentication problem in the
2282 Authentication Payload handling routines in
2283 lib/silccore/silcauth.c.
2285 * Yet another password authentication problem fixed with
2286 channel password handling in silcd/command.c.
2288 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * If first character of string in silc_parse_userfqdn is '@'
2291 then do not parse it. Affected file is
2292 lib/silcutil/silcutil.c.
2294 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed minor bug in IDENTIFY command reply sending, which
2297 caused various weird problems during JOIN when it was
2298 resolving names for users. Affected file silcd/command.c.
2300 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Fixed the IDENTIFY command reply sending to chech better valid
2303 clients. It was possible to send incomplete list of replies.
2304 Affected file silcd/command.c.
2306 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Added silc_client_command[s]_[un]register functions now to
2309 dynamically register the commands in client library. Removed
2310 the static table of commands. This allows the client library
2311 to call commands without causing the application to know about
2312 what commands library has called.
2314 Removed the INFO command reply kludge to detect when the command
2315 was called by library. Now library use its own command reply
2316 function for INFO command.
2318 Added function silc_client_command_call to call a command.
2319 Application can use it to call command, not access the structure
2322 Now all commands that are sent by the client library (not
2323 explicitly sent by application) use own command reply functions.
2325 Affected files around lib/silcclient/ and in
2326 irssi/src/silc/core/.
2328 * Fixed the WHOIS command reply sending to chech better valid
2329 clients. It was possible to send incomplete list of replies.
2331 Fixed the WHOIS and IDENTIFY to send the request to router
2332 if normal server did not do it and did not find any results.
2334 Affected file silcd/command.c.
2336 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Moved the internal data from SilcClient context into its
2339 own file, not accesible to application. Affected files
2340 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2341 and other files in client library.
2343 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added doc/examples installation target in Makefile.am.pre.
2348 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2351 commands the found client entry will be removed from the
2352 cache, after notifying application about the error. Affected
2353 file lib/silcclient/command_reply.c.
2355 * Changed the /MSG to check for exact nickname user gave, and
2356 not let `nick' match `nick@host' if it is only one found. Now,
2357 user must type the exact nickname (like nick@host2) even if
2358 there are no more than one same nicks found. This is to avoid
2359 a possibility of sending nickname to wrong nickname since
2360 `nick' could match `nick@host'. Affected file is
2361 irssi/src/core/silc-servers.c.
2363 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Do not print "you are now server operator" or similar when
2366 giving /away command. Affected files are
2367 irssi/src/silc/core/client_ops.c, silc-servers.h.
2369 * Made the silc_server_command_pending_error_check to send
2370 the same command reply payload it received back to the
2371 original sender of the command. This way all arguments
2372 that was received by the server will be received by the
2373 client too. Affected file silcd/command.c.
2375 * Added the silc_idcache_add to return the created cache entry
2376 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2378 * Add global clients to expire if they are not on any channel.
2379 This is because normal server will never know if they signoff
2380 if they are not on any channel. The cache expiry will take
2381 case of these entries. This is done by normal servers only.
2382 The affected files are silcd/command_reply.c,
2383 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2385 * If server receives invalid ID notification for WHOIS or
2386 IDENTIFY and the ID exists in the lists, it is removed.
2387 Affected file silcd/command_reply.c.
2389 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2390 in client then client entry that it matches is searched and
2391 the nickname is printed on the screen for user. Affected
2392 file irssi/src/silc/core/client_ops.c.
2394 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Use cache entry expire time in the LIST command reply to
2397 purge old entries from the cache after the LIST command
2398 reply has been received. This way we don't have non-existent
2399 entries in the cache for too long. Affected file is
2400 silcd/command_reply.c.
2402 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * If we are normal server, and we've not resolved client info
2405 in WHOIS or IDENTIFY from router, and it is global client,
2406 we'll check whether it is on some channel. If it is not
2407 then we cannot be sure about its validity and will resolve it
2408 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2409 file silcd/command.c.
2411 * Search channel by name (if possible) rather than by ID
2412 in IDENTIFY command's command reply. Affected file is
2413 silcd/command_reply.c.
2415 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2418 Updated specs and implemented it. Affected file silcd/command.c,
2419 silcd/packet_send.c and silcd/packet_receive.c.
2421 * Implemented the <founder auth> payload handling in the JOIN
2422 command. If provided all conditions for channel joining
2423 except requirement to provide correct passphrase can be
2424 overrided by the channel founder. Updated the protocol specs.
2425 Affected file silcd/command.c.
2427 Added support for founder auth in JOIN command in client
2428 library. Fixed the parsing of the JOIN command now to support
2429 all options as they should be. The affected file is
2430 lib/silcclient/command.c.
2432 * Optimized the WHOIS and IDENTIFY commands to send the request
2433 to router only if it includes nicknames or other names. If
2434 they include only IDs then check the local cache first before
2435 routing. Affected file is silcd/command.c.
2437 * Added channels topic announcements. Affected file is
2438 silcd/packet_receive.c and silcd/server.c.
2440 * Fixed the silc_server_send_notify_topic_set to really destine
2441 the packet to channel. Affected file silcd/packet_send.c.
2443 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2444 library. Affected file lib/silcclient/client_notify.c.
2446 * Added UMODE announcements. Affected file silcd/server.c.
2448 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Memory leak fixes in:
2452 lib/silcutil/silcsockconn.c
2453 lib/silcske/silcske.c
2454 lib/silcske/groups.c
2456 lib/silccrypt/silcpkcs.c
2457 lib/silccore/silccommand.c
2458 lib/silccore/silcidcache.c
2463 * ROBOdoc documented the lib/silcske/groups.h file and a
2464 bit changed the interface for better.
2466 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2468 * Update the client entry context in the ID cache after
2469 nick change. Affected file lib/silcclient/command.c.
2470 Fixes the CUMODE command when regaining founder privileges,
2471 and a little WHOIS problem.
2473 * Fixed silc_net_gethostbyname to correctly call the
2474 inet_ntop. Affected file lib/silcutil/silcnet.c.
2476 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2478 * Added IPv6 support checking to the configure.in.pre, added
2479 also --enable-ipv6 option to override the check. Affected
2480 file configure.in.pre.
2482 * The silc_thread_create now calls the start function
2483 directly if threads support is not compiled in. Removes
2484 ugly #ifdef's from generic code. Affected files are
2485 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2487 * Added silc_net_gethostby[name/addr]_async to asynchronously
2488 resolve. Affected files are lib/silcutil/silcnet.[ch].
2490 * Added support for rendering IPv6 based server, client and
2491 channel IDs. Affected file lib/silcutil/silcutil.c.
2493 * Added support for creating IPv6 based server IDs. Affected
2494 file is silcd/serverid.c.
2496 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2498 * Added silc_net_gethostby[addr/name] into the
2499 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2500 routines. Added silc_net_is_ip[4/6]. Affected file is
2501 lib/silcutil/unix/silcunixnet.c. All routines that take
2502 address as argument now supports both IPv4 and IPv6 addresses.
2504 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2506 * Fixed LIST command reply sending in server. Affected file
2509 * Server now sends the kicker's client ID in the KICK notify
2510 to the kicked client. Affected file silcd/command.c.
2512 * The client library now parses the kickers client ID and
2513 UI displays it. Affected files lib/silcclient/client_notify.c
2514 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2516 * Made all payload parsing function prototypes consistent.
2517 They all take now const unsigned char * and uint32 pair as
2518 the payload data instead of SilcBuffer. Changes all around
2519 the source tree. Other unsigned char* -> const unsigned char*
2520 changes around the tree as well.
2522 * Optimized SFTP client and server packet sending not to
2523 allocate new buffer for each packet but to recycle the
2524 first allocated buffer. Affected files are
2525 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2527 * Optimized the SFTP client to use SilcList instead of
2528 SilcDList for requests, because it is faster. Affected file
2529 is lib/silcsftp/sftp_client.c.
2531 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2532 into lib/silccore/silcid.[ch].
2534 Renamed silcpayload.[ch] into silcargument.[ch].
2536 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * If client entry is deleted with active key agreement
2539 session, abort the session.
2541 The silc_client_abort_key_agreement now calls the completion
2542 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2544 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2547 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Don't use __restrict in older GCC's. Affected file is
2550 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2552 * silc_net_localhost now attempts to reverse lookup the
2553 IP/hostname. Affected file lib/silcutil/silcnet.c.
2555 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2556 command. It can be used to gain founder privileges at
2557 the same time when joining the channel.
2559 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2560 kicker's client ID as well. Updated protocol specs.
2562 Defined that the server must send SILC_COMMAND_IDENTIFY
2563 command reply with error status to client who sent
2564 private message with invalid client ID.
2566 Updated the protocol specification.
2568 * Added silc_server_send_command_reply to send any
2569 command reply. Affected file silcd/packet_send.[ch].
2571 * Added silc_id_payload_encode_data to encode ID payload
2572 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2574 * The server now send IDENTIFY command reply with error
2575 status if client ID in private message is invalid. Affected
2576 file silcd/packet_receive.c.
2578 * Save the server key file with server's IP address in
2579 the filename instead of hostname. The affected file is
2580 irssi/src/silc/core/client_ops.c.
2582 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2587 * Added libtool support for compiling shared objects in
2588 lib/silcsim. Affected file configure.in.pre and
2589 lib/silcsim/Makefile.am. Original patch by cras.
2591 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Pid file configuration, and server's config file fixes
2594 patch by toma. Updated CREDITS file.
2596 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Fixed silc_client_channel_message to not try to decrypt
2599 the message twice if it resolved the destination client
2600 information. This could cause of dropping one channel
2601 message. Affected file lib/silcclient/client_channel.c.
2603 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2606 lib/silcclient/client.c. This function is used when the SILC
2607 Client is run under some other scheduler, or event loop or
2608 main loop. On GUI applications, for example this may be
2609 desired to used to run the client under the GUI application's
2610 main loop. Typically the GUI application would register an
2611 idle task that calls this function multiple times in a second
2612 to quickly process the SILC specific data.
2614 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2616 * Fixed silc_server_drop() for dropping the supplementary
2617 groups as well, this could cause a security hole on some
2620 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2625 * Write PID file after dropping privileges. Added -F option
2626 to run server on foreground. A patch by debolaz.
2627 Affected files silcd/server.c, silcd/silcd.c.
2629 * Fixed MOTD to return the MOTD file server name. Affected
2630 file silcd/command.c.
2632 * Added INFO command reply handling to the Irssi SILC Client.
2633 Affected file irssi/src/silc/core/client_ops.c.
2635 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Fixed the silc_idcache_list_* routines to really support
2638 the dynamic list. Fixes a crash. Affected file is
2639 lib/silccore/silcidcache.c.
2641 * Fixed the LIST command reply to really call LIST command's
2642 pending callbacks. Affected file silcd/command_reply.c.
2644 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Update conn->local_entry->nickname after giving NICK
2647 command. Affected file lib/silcclient/command.c.
2649 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2651 * Added the [pid] option to the silcd configuration file
2653 Affected files: serverconfig.[ch] and silcd.c
2655 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Save fingerprint in WHOIS command reply in server.
2658 Affected file silcd/command_reply.c.
2660 * Fixed NICK commands pending callback registration.
2661 Affected file lib/silcclient/command.c.
2663 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2665 * Use ++server->cmd_ident when sending commands in server,
2666 instead of random number. Affected file silcd/command.c.
2668 * Fixed GETKEY command reply to call actually GETKEY pending
2669 command callbacks. Affected file silcd/command_reply.c.
2671 * A bit stricter check for nicknames. Check for same nickname
2672 in NICK command also. Affected file silcd/command.c.
2674 * Do not call INFO command everytime client ID changes, only
2675 during first connecting. Affected file lib/silcclient/client.c.
2677 * Set the new nickname only after successful command reply for
2678 NICK command is returned by server. Affected file
2679 lib/silcclient/command.c.
2681 * Remove nicknames from nicklist during server_signoff notify.
2682 Should fix /NAMES bit more. The affected file is
2683 irssi/src/silc/core/silc-channels.c.
2685 * Added `fingerprint' field to the SilcIDListData in the
2686 silcd/idlist.h to hold the fingerprint of the client's
2689 Send the fingerprint of the client's public key in WHOIS
2692 Affected files silcd/command.c, and silcd/idlist.[ch].
2694 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2695 create fingerprint from given data.
2697 * Show the fingerprint of the client's public key in WHOIS.
2698 Affected files irssi/src/module-formats.[ch] and
2699 irssi/src/silc/core/client_ops.c.
2701 * Format the multiple same nicknames also during JOIN and
2702 NICK_CHANGE notifys. Affected file is
2703 lib/silcclient/client_notify.c.
2705 * Do not print error on screen for invalid private message
2706 payload since it can come if someone is sending private
2707 messages with wrong key. Affected file
2708 lib/silccore/silcprivate.c.
2710 * Fixed multiple concurrent /PING crash. Affected file
2711 lib/silcclient/command.c.
2713 * Changed the wrong ID encoding. All IP addresses must be
2714 in MSB first order in encoded format. They were encoded
2715 wrong and was in LSB format. Affected files are
2716 silcd/serverid.c, lib/silcutil/silcutil.c.
2718 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2720 * Call the `connect' client operation through the scheduler
2721 in case of error. Affected file lib/silcclient/client.c.
2723 * Call the `failure' client operation even if the error
2724 occurred locally during a protocol. Affected file is
2725 lib/silcclient/protocol.c.
2727 * Added support of sending LIST command to router from normal
2728 server. This way normal server can get list of all channels
2729 in the network too. Fixed the channel list sending in the
2730 server too. Affected files are silcd/command.c, and
2731 silcd/command_reply.[ch].
2733 * Added silc_server_update_channels_by_server and
2734 silc_server_remove_channels_by_server. They are used during
2735 disconnection of primary router and in backup router protocol.
2736 Affected file silcd/server_util.[ch], silcd/server.c and
2737 silcd/server_backup.c.
2739 * Fixed channel adding to global list in IDENTIFY command
2740 reply in server. Affected file silcd/command_reply.c.
2742 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * If the incoming packet type is REKEY or REKEY_DONE process
2745 that packet always synchronously. Fixes yet another MAC
2746 failed error on slow (dialup) connections. Affected file
2747 lib/silcclient/client.c and silcd/server.c.
2749 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Call check_version SKE callback for initiator too. Affected
2752 file lib/silcske/silcske.c.
2754 * Implemented fix for security hole found in the SKE that was
2755 fixed in the specification few days back; the initiator's
2756 public key is now added to the HASH value computation.
2757 Added backwards support for the old way of doing it too, for
2758 old clients and old servers. Affected file is
2759 lib/silcske/silcske.c.
2761 * Enabled mutual authentication by default in SKE. If initiator
2762 is not providing mutual authentication the responder will
2763 force it. This will provide the proof of posession of the
2764 private key for responder. The affected files are
2765 lib/silcclient/protocol.c and silcd/protocol.c.
2767 * Do not cache anymore the server's public key during SKE.
2768 We do mutual authentication so the proof of posession of
2769 private key is done, and if the server is authenticated in
2770 conn auth protocol with public key we must have the public
2771 key already. Affected file silcd/protocol.c.
2773 * Added new global debug variable: silc_debug_hexdump. If
2774 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2775 file lib/silcutil/silclog.[ch].
2777 * Fixed compilation warning due to char * -> const char *.
2778 Affected files lib/silcutil/silcnet.h, and
2779 lib/silccore/silcauth.[ch].
2781 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Fixed CMODE command when new channel key was created. If
2784 the creation failed the old key was removed. Next time giving
2785 same command would crash the server since the old key was
2786 freed already. Affected file silcd/command.c.
2788 * Fixed the silc_server_announce_get_channels to not crash
2789 on reconnect. Affected file silcd/server.c.
2791 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Added silc_log_set_debug_string function to set a regex
2794 string to match for debug output. Only the function names,
2795 or filenames matching the given debug string is actually
2796 printed. This way it is possible to filter out those debug
2797 strings that user is not interested in.
2799 Fixed a bug in silc_string_regexify.
2801 Affected files lib/silcutil/silclog.[ch], and
2802 lib/silcutil/unix/silcunixutil.c.
2804 * Changed the -d options in both server and Irssi SILC client
2805 to take the debug string as argument. Affected files
2806 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2808 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Added silc_hash_babbleprint to create a Bubble Babble
2811 Encoded fingerprint. The encoding is developed by Antti
2812 Huima (draft-huima-babble-01.txt), and it creates human
2813 readable strings out of binary data. Affected file
2814 lib/silccrypt/silchash.[ch].
2816 * Print the babble print now in addition of fingerprint as well
2817 in Irssi SILC client. Affected files are
2818 irssi/src/fe-common/silc/module-formats.[ch],
2819 irssi/src/fe-common/silc/core/client_ops.c.
2821 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Fixed a security problem found in SKE. The initiator's
2824 public key too is now added to the HASH hash value creation
2825 which is signed by the responder to create the SIGN value.
2826 This will prevent anyone in the middle to lie to the responder
2827 about the initiator's public key. If this is done now, the
2828 man in the middle will get caught. Updated the protocol
2831 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Better installation directory handling. Configure module
2834 paths and other paths automatically to example_silc* files
2835 in doc/. A patch by toma.
2837 * Fixed compiler warning from MPI library, and from SILC RNG.
2840 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2841 It can be configured with ./configure. A patch by toma.
2843 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Find correct make to use in prepare-clean. A patch by
2846 toma. Affected file prepare-clean.
2848 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2850 * Added irssi variables use_auto_addr, auto_bind_ip,
2851 auto_bind_port and auto_public_ip.
2853 * Changed the interface for silc_client_send_key_agreement
2854 in lib/silcclient/silcapi.h
2858 irssi/src/silc/core/silc-core.c
2860 lib/silcclient/silcapi.h
2861 irssi/src/silc/core/silc-channels.c
2862 lib/silcclient/client_keyagr.c
2865 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Added silc_pkcs_public_key_compare to compare two
2868 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2870 * Check that the client who set the founder mode on the
2871 channel is the same client that is giving the founder
2872 mode to itself. It is done by comparing the saved public
2873 key (it is saved even in the authentication is passphrase).
2874 Affected file silcd/command.c.
2876 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Do not process packet for disconnected socket connection.
2879 Affected file lib/silccore/silcpacket.c.
2881 * Process the DISCONNECT packet through scheduler in the
2882 client library. Affected file lib/silcclient/client.c.
2884 * Fixed the silc_client_packet_parse to not to increase
2885 the packet sequence number if the conn->sock and the
2886 current socket connection is not same. This can happen
2887 for example during key agreement when the conn includes
2888 multiple socket connections (listeners). Affected file
2889 lib/silcclient/client.c.
2891 * The sender of the file transfer request now provides also
2892 the pointer (listener) for the key exchange protocol. If
2893 the listener cannot be created then it sends empty key
2894 agreement and lets the receiver provide the listener.
2896 Added `local_ip' and `local_port' arguments to the
2897 silc_client_file_send. If they are provided they are used,
2898 if not then it will attempt to find local IP address, if
2899 not found or bind fails then the remote client will provide
2902 Affected files are lib/silcclient/client_ftp.c and
2903 lib/silcclient/silcapi.h.
2905 * Extended the FILE SEND command to support defining the
2906 local IP and port for key exchange listener. They are
2907 optional. Affected file irssi/src/silc/core/silc-servers.c.
2909 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Defined to WHOIS command reply the sending of fingerprint
2912 of the client's public key (if the proof of posession of the
2913 corresponding private key is verified by the server).
2914 Updated to the protocol specification.
2916 * Added support of receiving the client's public key's
2917 fingerprint in command reply in client library. Affected
2918 file is lib/silcclient/command_reply.c, and
2919 lib/silcclient/idlist.[ch].
2921 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Do not send over 128 chars long nickname to the server
2924 in NICK command. Affected file lib/silcclient/command.c.
2926 * Do not send over 256 chars long channel names to the server
2927 in JOIN command. Affected file lib/silcclient/command.c.
2929 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Assure that silc_server_close_connection cannot be called
2932 twice for same socket context. Affected file is
2935 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Send error message to application if opening file for
2938 writing during file transfer fails. Affected file is
2939 lib/silcclient/client_ftp.c.
2941 Remove all file transfer sessions for a client that we're
2942 removing from ID cache.
2944 Affected file is lib/silcclient/client_ftp.c.
2946 * Fixed silc_net_addr2bin to return correct address. Affected
2947 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2949 * Fixed file transfer session removing on signoff notify.
2950 Affected file irssi/src/silc/core/silc-servers.c.
2952 * Added the SilcClientFileError to be returned in the monitor
2953 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2954 Affected file lib/silcclient/silcapi.h.
2956 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed a crash in silc_client_ftp_free_sessions and
2959 silc_client_ftp_session_free_client. Affected file
2960 lib/silcclient/client_ftp.c.
2962 * Added `disabled' field in the SilcChannelEntry in the server
2963 to indicate if the server entry is disabled. Affected file
2964 silcd/idlist.h, silcd/command[_reply].c.
2966 * SILC server adds now /var/run/silcd.pid everytime it is
2967 started. Affected file silcd/silcd.c.
2969 * Added silc_server_packet_send_clients to send a packet to
2970 the provided table of client entries. Affected file
2971 silcd/packet_send.[ch].
2973 * Fixed a crash in client resolving in client_prvmsg.c in
2974 client library. Affected file lib/silcclient/client_prvmsg.c.
2976 * Do not actually remove the client directly from ID cache
2977 during SERVER_SIGNOFF, but invalidate it. This way we
2978 preserve the WHOWAS info for the client. Affected file
2979 silcd/server_util.c.
2981 * Fixed SERVER_SIGNOFF notify handling in the server. The
2982 server is now able to process incoming SERVER_SIGNOFF notify
2983 for a server that it doesn't even know about. It will remove
2984 the clients provided in the notify. Affected file
2985 silcd/packet_receive.c.
2987 * Check for partial packet in data queue after every packet that
2988 was found from the queue. Return and wait for more data if
2989 there is partial data in queue. Affected file is
2990 lib/silccore/silcpacket.c.
2992 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2996 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2997 Affected files lib/silcclient/silcapi.h and
2998 lib/silcclient/client_ftp.c.
3000 * Check that newsize in silc_buffer_realloc is larger than
3001 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3003 * Added better monitor of file transfers. It now monitors
3004 key agreement protocol during the file transfer too. Added
3005 error reporting too. Affected files
3006 irssi/src/silc/core/silc-servers.c,
3007 irssi/src/fe-common/silc/module-formats.[ch].
3009 * Wrote a help file for FILE command.
3011 * Added silc_rng_global_get_byte_fast to get not-so-secure
3012 random data as fast as possible. Random data is read from
3013 /dev/urandom if available and from the SILC RNG if not
3014 available. It is used in padding generation. Affected file
3015 lib/silccrypt/silcrng.[ch].
3017 * All packets in client library are now processed synchronously.
3018 Optimized packet processing a lot. Affected file
3019 lib/silcclient/client.c.
3021 * All server connection packets are processing synchronously
3022 now in server, to optimize packet processing. Affected file
3025 * Include files are installed now only in Toolkit distribution
3026 if make install is given. Affected files: all Makefile.am's.
3028 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Assure that silc_client_notify_by_server_resolve does not
3031 resolve the client information multiple times. If it cannot
3032 be found by the first it cannot be found at all. Affected
3033 file lib/silcclient/client_notify.c.
3035 * Fixed WHOWAS command reply calling. Affected file
3036 lib/silcclient/command_reply.c.
3038 * Removed all references to silc_idlist_get_client from the
3039 Irssi SILC client since that call is internal call used by
3040 the library. The Irssi SILC client will use now client
3041 retrieval functions found in silcapi.h.
3043 * Fixed a bug in resolving nickname info before sending
3044 private message. It used freed memory. Affected file
3045 irssi/src/silc/core/silc-servers.c.
3047 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Assure my_channels statistics cannot go negative in server.
3050 Affected files silcd/server.c, silcd/server_util.c.
3052 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3064 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Added silc_net_localip to return local host's IP address.
3067 Affected file lib/silcutil/silcnet.[ch].
3069 * If key exchange or rekey protocol is active for a connection
3070 parse all packets syncronously since there might be packets
3071 in packet queue that we are not able to process without first
3072 processing packets before them. Affected file silcd/server,
3073 lib/silcclient/client.c.
3075 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3076 whether library should continue processing the packet.
3077 Affected file lib/silccore/silcpacket.h.
3079 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3107 silc_file_open and silc_file_close. Affected files
3108 lib/silcutil/silcutil.[ch].
3110 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Resolve the client info when received private message or
3113 channel message for a client which nickname we don't know.
3114 Affected files lib/silcclient/client_prvmsg.c and

3124 is incomplete and is being resolved, it won't be resolved
3127 Make sure also that USERS command reply does not resolve
3128 twice information. Affected file is
3129 lib/silcclient/command_reply.c.
3131 Make sure that silc_client_get_clients_by_list does not
3132 resolve twice same information.
3134 * Check for valid client->id in the silc_server_free_client_data.
3135 Affected file silcd/server.c.
3137 * Fixed /GETKEY nick@server not to crash if the server entry
3138 is not found. Affected file lib/silcclient/command.c.
3140 * Fixed the silc_server_check_cmode_rights to check the
3141 requested modes correctly. Affected file silcd/command.c.
3143 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Better checks for non-printable chars in nick added.
3146 Affected file silcd/command.c.
3148 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Call the silc_server_udpate_servers_by_server in the
3151 primary router that comes back online in the backup resuming
3152 protocol. Otherwise it routes packets wrong. Affected file
3153 silcd/server_util.[ch], silcd/server_backup.c.
3155 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3158 lib/silcutil/silcbuffmt.[ch].
3160 * Redefined the SILC packet header to include the padding
3161 length. Affected file lib/silccore/silcpacket.[ch].
3163 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3164 length for maximum padding up to 128 bytes). Affected
3165 file lib/silccore/silcpacket.h.
3167 * Removed all backwards support for old 0.5.x MAC thingies.
3168 The SILC packet header change makes it impossible to be
3169 backwards compatible.
3171 * Send the ENDING packet with timeout in the backup resuming
3172 protocol. This is to assure that all routers has connected
3173 to the primary router. Affected file silcd/server_backup.c.
3175 * Changed the RNG to take the first IV from random data. It
3176 used to take it from zero actually. Changed the RNG also
3177 to use /dev/urandom during session. /dev/random is used
3178 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3180 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Changed the SILC packet header to have the first two bytes
3183 (the packet length) encrypted. Affected files aroung the
3184 code tree, lib/silccore/silcpacket.[ch]. Removed the
3185 SilcPacketCheckDecrypt callback. It is not needed anymore
3186 since the silc_packet_receive_process will determine now
3187 whether the packet is normal or special.
3189 * Implemented the unidirectional MAC keys. Affected files
3190 lib/silcske/silcske.c, silcd/protocol.c and
3191 lib/silcclient/protocol.c.
3193 * Implemented the packet sequence number to the MAC computation.
3194 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3195 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3196 lib/silcclient/protocol.c.
3198 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Allow backup router to announce servers. All servers
3201 announced by backup router are added to the global list
3202 automatically. Update hte server's socket to our primary
3203 router also when backup router announces a server.
3204 Affected file silcd/packet_receive.c.
3206 * Do not update the client->router in the function
3207 silc_server_udpate_clients_by_server if the client is on
3208 global list. We might fail to find any specific server
3209 for locally connected clients and local cell clients. They
3210 should still use the `from' and not `to' as client->router.
3211 This fixes backup router resuming protocol. Affected file
3212 silcd/server_util.c.
3214 * Decrease channel statistics count only if the channel
3215 deletion worked. Affected files are silcd/server.c and
3216 silcd/server_util.c.
3218 * Added silc_server_update_servers_by_server to update origin
3219 of all server entries. Used during backup router protocol.
3220 Affected files silcd/server_util.[ch], silcd/server.c. and
3221 silcd/backup_router.c.
3223 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3224 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3225 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3226 lib/silccrypt/silchmac.c.
3228 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * Assure that router cannot reroute the same channel message
3231 to the sender. Affected file silcd/packet_receive.c.
3233 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Made better checks that the channel message is not sent
3236 to the router it came from. Affected file is
3237 silcd/packet_send.c. Fixed memory leak too.
3239 * Announce informations for incoming router connection, but
3240 only after checking if it is replaced by backup router.
3241 Affected file silcd/packet_receive.c.
3243 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Fixed the backup resuming protocol to work in multiple
3246 router environment. Affected file silcd/server_backup.c.
3248 * Route packet only to one router in the function
3249 silc_server_packet_send_to_channel. Affected file is
3250 silcd/packet_send.c.
3252 * Fixed silc_server_send_notify_dest to set the broadcast
3253 flag. Fixed the silc_server_send_notify_topic to actually
3254 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3255 Affected file silcd/packet_send.c.
3257 * Changed the SFTP Filesystem interface. Changed the
3258 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3259 the filesystem operation function. The SilcSFTPFilesystem
3260 is now a context that is allocated by all filesystem allocation
3261 functions and it already includes the operations structure
3262 and filesystem specific context. It is given as argument
3263 now to the silc_sftp_server_start. This made the interface
3264 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3265 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3267 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Changed the backup router adding and getting interfaces
3270 in the server. The router that will be replaced by the
3271 specified backup router is now sent as argument. Affected
3272 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3275 * Added silc_net_addr2bin_ne to return the binary form of
3276 the IP address in network byte order. Affected files
3277 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3279 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3281 * Check for existing server ID in silc_server_new_server
3282 and in silc_server_connect_to_router_final and remove the
3283 old entry if it exists. Affected file silcd/packet_receive.c,
3286 * Send the channel message always to only one router, either
3287 in upstream or downstream. Affected file is
3288 silcd/packet_send.c.
3290 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Wrote the definition of the backup resuming protocol to the
3293 protocol specification.
3295 * Removed one redundant channel key generation from normal
3296 server during joining procedure. Removed one redundant
3297 channel key sending from server to router during joining
3298 procedure. Affected file silcd/command.c.
3300 * Made minor bugfixes to the backup router resuming protocol.
3301 Affected file silcd/server_backup.c, server.c.
3303 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Added --disable-asm configuration option. Affected files
3306 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3309 * Implemented the backup resuming protocol that is used to
3310 resume the primary router position in the cell after the
3311 primary router comes back online. Affected files
3312 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3313 and silcd/server_util.[ch].
3315 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Sleep two (2) seconds after sending QUIT command to server.
3318 Affected file lib/silcclient/command.c.
3320 * Assure that if outgoing data buffer is pending do not force
3321 send any data. Affected file silcd/packet_send.c.
3323 * Assure that if outgoing data buffer is pending do not force
3324 send any data. Affected file lib/silcclient/client.c.
3326 * Implemented the backup router support when the primary router
3327 goes down. The servers and routers can now use the backup
3328 router as new primary router without loosing connectivity.
3330 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3332 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3333 in the server to indicate disabled entry. All data read
3334 from the connection will be ignored and no data is sent
3335 for entry that is disabled. Affected files are
3336 silcd/idlist.h, silcd/server.c.
3338 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Created SFTP client and server test programs in the
3341 lib/silcsftp/tests directory.
3343 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Implemented memory filesystem (virtual filesystem) for
3346 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3349 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3351 * Implemented the SFTP (SSH File Transfer Protocol) to the
3352 lib/silcsftp. It includes SFTP client and SFTP server
3355 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Moved lib/silccore/silcprotocol.[ch] to the
3358 lib/silcutil library.
3360 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3361 take variable argument list pointer as argument. Affected
3362 file lib/silcutil/silcbuffmt.[ch].
3364 * Added silc_buffer_set function that is used to set data
3365 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3366 Affected file lib/silcutil/silcbuffer.h.
3368 * Changed various routines in the core library to use the new
3369 silc_buffer_set instead of allocating new buffer only for
3372 * Added 64-bit value formatting and unformatting support to the
3373 silc_buffer_[un]format routines. Affected file is
3374 lib/silcutil/silcbuffmt.[ch].
3376 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3377 to includes/bitmove.h.
3379 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Fixed channel user mode saving in client library. Affected
3382 file lib/silcclient/command[_reply].c.
3384 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3386 * Defined the file transfer to the SILC Protocol. Added
3387 new packet type SILC_PACKET_FTP and defined File Transfer
3388 Payload. The mandatory file transfer protocol is SFTP
3389 (SSH File Transfer Protocol). Affected file in addition
3390 of the internet draft is lib/silccore/silcpacket.h.
3392 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3393 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3394 is used as part of backup router protocol when the primary
3395 router of the cell is back online and wishes to resume
3396 the position as primary router.
3398 * Redefined the MAC generation keys in the protocol. The
3399 same key is not used anymore in both direction. Both
3400 direction will now use different keys for sending and
3401 receiving. This fixes a potential security flaw. This
3402 change causes incompatibilities in the protocol.
3404 * Redefined also the MAC computation from the packet.
3405 An packet sequence number is now added to the MAC
3406 computation. This prevents possible replay attacks against
3407 the protocol. This change too causes incompatibilities
3410 Added `sequence' field to the SilcPacketContext to hold
3411 the current sequence number for the packet.
3413 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * Added `created' field to the SilcIDListData in the file
3416 silcd/idlist.h to indicate the time when the entry was
3419 * Added `created' field to the SilcChannelEntry too. Affected
3420 file silcd/idlist.h.
3422 * Added `creation_time' aguments to all the announcement functions
3423 in the server. If it is provided then only the entries that
3424 was created after the provided time frame are actually
3425 announced. Affected file silcd/server.[ch].
3427 * The protocol says that the Channel ID's IP address must be
3428 based on the router's IP address. Added check for this in
3429 the silc_server_new_channel when processing incoming New Channel
3430 Payload. Affected file silcd/packet_receive.c.
3432 * Print out the correct version with --version in SILC client.
3433 Affected file irssi/src/silc/core/silc-core.c.
3435 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Fixed WHOWAS command to check for completnes of the client
3438 entry always, not just when the command is coming from client.
3439 Affected file silcd/command.c.
3441 * Added new function silc_server_packet_queue_purge to purge the
3442 outgoing data queue to the network. After the function returns
3443 it is guaranteed that the outgoing packet queue is empty.
3444 Affected file silcd/packet_send.[ch].
3446 * Purge the outgoing packet queue in the rekey protocol's final
3447 callback to assure that all rekey packets go to the network
3448 before quitting the protocol. Affected file silcd/server.c.
3450 * Added silc_client_packet_queue_parse as similar function as
3451 in server to the client library. The affected file is
3452 lib/silcclient/client.c.
3454 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Splitted silcd/server.c and created silcd/server_util.[ch]
3457 for utility functions.
3459 * Added new socket flag SILC_SF_DISABLED to indicate that the
3460 connection is open but nothing can be sent to or received from
3461 the connection. Affected file lib/silcutil/silsockconn.[ch].
3462 The checking for disabled socket is checked in the low level
3463 silc_socket_write and silc_socket_read functions.
3465 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Allow only nicknames and channel names that fits into the
3468 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3470 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * When processing JOIN command reply in server check that if
3473 the channel exists in our global list we'll move it the local
3474 list. Affected file silcd/command_reply.c.
3476 * Fixed the check whether client is joined on the channel already
3477 in JOIN command. Affected file lib/silcclient/command.c.
3479 * Fixed the JOIN command reply to check whether the channel
3480 already exists. Affected file lib/silcclient/command_reply.c.
3482 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Added silc_ske_status_string to map the SKE error numbers
3485 to readable strings. The affected files are
3486 lib/silcske/silcske[_status].[ch].
3488 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3490 * Do not show the private channels on the WHOIS channel list
3491 as it is not allowed by the protocol. The affected file is
3494 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Assure that the packet length digged from the actual packet
3497 is something sensible in the silc_packet_decrypt_rest_special
3498 in lib/silccrypt/silcpacket.c.
3500 * Free and NULL the allocated pointer in silc_hmac_alloc if
3501 the HMAC allocation fails. The affected file is
3502 lib/silccrypt/silchmac.c.
3504 * Print the selected security properties to the log files in
3505 the server. Affected file silcd/protocol.c.
3507 * Add SKE's reference counter even if calling the completion
3508 callback manually. Otherwise it goes negative, although it
3509 does not cause any problems. The affected file is
3510 lib/silcske/silcske.c.
3512 * Remove the client entry with short timeout after giving the
3513 KILL command. Affected file lib/silcclient/command.c.
3515 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3516 case all found clients are already disconnected (WHOWAS would
3517 found them) in the server. Affected file silcd/command.c.
3519 * Update the last_receive (time of last data received) to be
3520 updated only when received private or channel message so that
3521 the idle time showed in WHOIS makes more sense.
3523 * Added boolean field `valid' in to the SilcClientEntry in the
3524 client library to indicate whether the entry is valid or not.
3525 This fixes the nickname change bug on channel when changing
3526 the nickname to be same than the old (like nick to Nick) the
3527 nickname formatter doesn't set the new nick anymore to Nick@host.
3528 Affected file lib/silcclient/idlist.[ch].
3530 * Now actually fixed the nickname changing on disconnection.
3531 Added new function silc_change_nick to the Irssi SILC Client.
3532 Affected file irssi/src/silc/core/client_ops.c,
3533 irssi/src/silc/core/silc-nicklist.[ch].
3535 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Check that the public key exists in the GETKEY command before
3538 trying to encode it. Affected file silcd/command.c.
3540 * Print some notifications on received public keys with GETKEY
3541 command in the Irssi SILC Client. Affected files are
3542 irssi/src/fe-common/silc/module-formats.[ch],
3543 irssi/src/silc/core/client_ops.c.
3545 * Use IDENTIFY command to resolve the server information in the
3546 GETKEY command instead of INFO command. Affected file
3547 lib/silcclient/command.c.
3549 * All command reply functions in the client library now calls
3550 the pending command reply callbacks even if an error has
3551 occurred. The server has done this a long time and now it was
3552 time to move the client library to this as well. Now all
3553 errors can be delivered back to the pending command reply
3554 callbacks if necessary. Affected files are
3555 lib/silcclient/command[_reply].[ch].
3557 * Change the nickname on disconnection back to the username
3558 because in reconnect the server will enforce it to it anyway.
3559 Affected file irssi/src/silc/core/silc-servers.c.
3561 * Fixed a config file parsing bug in the Irssi SILC client.
3562 Affected file irssi/src/silc/core/clientconfig.c.
3564 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3566 * When printing the channel mode on JOIN, verify that the
3567 channel key and channel's HMAC are valid. Affected file
3568 irssi/src/silc/core/client_ops.c.
3570 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3572 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3573 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3574 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3576 * Removed channel key rekey task deleting from the function
3577 silc_server_save_channel_key. Affected file silcd/server.c.
3578 Added explicit timeout task context instead that is used to
3579 delete the task if we are registering a new task before the
3580 new task has elapsed.
3582 * When channel key rekey occurs the client library now saves
3583 the old channel key for a short period of time (10 seconds) and
3584 is able to use it in case some is still sending channel
3585 messages encrypted with the old key after the rekey. Affected
3586 file lib/silcclient/[idlist.h|client_channel.c].
3588 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * Added check to the silc_server_new_id_real to not accept
3591 new ID if it is the sender's own ID. Affected file is
3592 silcd/packet_receive.c.
3594 * Assure that we do not announce ourself or the one we've
3595 sending our announcements when we're router and are announcing
3596 servers to our primary router. Affected file silcd/server.c.
3598 * Fixed silc_server_command_identify_check_client to assemble
3599 correct WHOIS packet. It send corrupted WHOIS packet and
3600 caused problem with router to router connections. Affected
3601 file silcd/command.c.
3603 Fixed also silc_server_command_whois_check the same way
3604 as for the IDENTIFY command.
3606 * Added new SilcIDListStatus to the server in the SilcIDListData
3607 structure. The status now includes the current status of
3608 the entry (like registered, resolved etc.). Affected file
3609 silcd/idlist.[ch]. Defined a bunch of different status types
3610 as well. This replaced the old boolean registered field as well.
3612 Added resolve_cmd_ident field to the SilcClientEntry structure
3613 too so that if the entry is for example being resolved so
3614 another command may attach to the same pending command reply
3615 without requiring to resolve the same entry again. This concept
3616 should optimize the WHOIS and the IDENTIFY resolving under
3617 heavy load by taking away unnecessary resolving for entries
3618 that are being resolved already.
3620 Added support for adding multiple pending commands for one
3621 command idenfier. Affected file silcd/command[_reply].[ch].
3623 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3624 before deleting the data. Otherwise the hash table will have
3625 freed data in comparison functions. Affected file is
3626 silcd/command_reply.c.
3628 * Fixed silc_idlist_replace_client_id to add the new entry to
3629 the cache with NULL nickname. Otherwise there will be invalid
3630 memory as the nickname after the nickname is freed. Affected
3631 file silcd/packet_receive.c.
3633 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3634 saved into wrong slots because the previous number of entries
3635 was not taken into account. Affected file silcd/idlist.c.
3636 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3638 * If we are router and we receive JOIN notify to a channel that
3639 does not have any users then notified client is marked as the
3640 channel founder, as it is it. The affected file is
3641 silcd/packet_receive.c
3643 * Added to the extended hash table API's table_del_*ext functions
3644 the destructor as argument too, so that the caller can decide
3645 which destructor to use or whether to use destructor at all.
3646 Affected file lib/silcutil/silchashtable.[ch].
3648 * Fixed ID Cache purging. It actually deleted the entries from
3649 the hash table after the data was freed. The hash table ended
3650 up comparing freed memory. The affected file is
3651 lib/silccore/silcidcache.c.
3653 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Fixed Irssi SILC client's KILL command's HELP syntax.
3657 * The USERS command now resolves the detailed user information
3658 if the userinfo field is missing. Affected file is
3659 lib/silcclient/command_reply.c.
3661 * Do not print error in silc_file_read if the read file does
3662 not exist. Just silently return NULL. Affected file is
3663 lib/silcutil/silcutil.c.
3665 * Fixed the silc_log_output to not wine about NULL filename
3666 and to not create some bogus " " filename. Affected file is
3667 lib/silcutil/silclog.c.
3669 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * Fixed various printing bugs on the user interface in the
3672 Irssi SILC Client. Minor changes that were forgotten from
3675 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Fixed the configure.in.pre and the compilation and distribution
3678 environment to support the new autoconf 2.52. That version is
3679 now required to compile the CVS trunk.
3681 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3684 to generally parse user@fqdn format strings. Affected file
3685 lib/silcutil/silcutil.c.
3687 * Added nickname_format and nickname_force_format fields to the
3688 SilcClientParams structure. The first one defines the format
3689 for the nicknames that the library will enforce if the receives
3690 multiple same nicknames. The second one is boolean value and
3691 can be used to force the library to always enforce the format
3692 to the nicknames regardles whether there are multiple nicknames
3693 or not. This configurable formatting was employed to flexibly
3694 support accessing multiple nicknames from the user interface.
3695 The userinterface can now set the nicknames to what ever format
3696 they prefer. Affected file lib/silcclient/silcapi.h.
3698 Added function silc_client_nickname_format to the file
3699 lib/silcclient/idlist.c. It performs the nickname formatting.
3701 Added new field `hostname´ to the SilcClientEntry context.
3702 It holds the hostname of the client. Affected file is
3703 lib/silcclient/idlist.h.
3705 * Irssi SILC Client sets the nicknames in nick@hostn format.
3706 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3707 irssi/src/silc/core/silc-core.c.
3709 The WHOIS printing now also shows both the real nickname and
3710 the formatted nickname so that user knows how to access the
3711 user if there are multiple same nicknames cached. Affected
3712 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3713 printing formatting too to take the hostname now as a separate
3714 argument. The Affected file is
3715 irssi/src/fe-common/silc/modules-formats.[ch].
3717 * Changed the silc_client_get_clients_local to accept the formatted
3718 nickname as argument. It accepts the real nickname too but the
3719 formatted nickname can be used to find the true entry from
3720 multiple entries. Affected file lib/silcclient/silcapi.h and
3721 lib/silcclient/idlist.c.
3723 * Added nickname_format_parse field to the SilcClientParams.
3724 It is a callback function provided by the application to parse
3725 the nickname out of the formatted nickname string. The library
3726 calls it to get the nickname from the formatted string. Since
3727 the application generally knows better the format of the nickname
3728 string it parses it instead of the library, even though library
3729 encodes the formatted string. If the callback function is not
3730 provided then the library will use the string as is. The
3731 affected file is lib/silcclient/silcapi.h.
3733 * All the nickname strings passed to the client library in
3734 commands are now expected to be formatted nickname strings.
3735 If the command does not support the formatted nickname string
3736 it will assume that the sent string is the actual nickname.
3737 Affected file lib/silcclient/command.c.
3739 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Added public key authentication support to OPER and SILCOPER
3742 commands in the client library. Affected file is
3743 lib/silcclient/command.c.
3745 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Changed the get_auth_methdod client operation to be asynchronous.
3748 It can be async if the application resolves the authentication
3749 method from the server during the negotiation. Added new
3750 SilcGetAuthMeth completion callback that the application will
3751 call after resolving the authentication method.
3753 Added function silc_client_request_authentication_method that
3754 the application can use to resolve the authentication method
3755 from the server. Added also SilcConnectionAuthRequest callback
3756 that the library will call after the server has replied. The
3757 application can call this function if it does not know the
3758 current authentication method.
3760 Affected files are lib/silcclient/client.c and
3761 lib/silcclient/silcapi.h.
3763 * The Irssi SILC client now automatically resolves the authentication
3764 method incase any configuration information is not present (and
3765 currently there never is). The affected file is
3766 irssi/src/silc/core/client_ops.c.
3768 * Fixed public key authentication from the client library.
3769 Affected file lib/silcclient/protocol.c. Changed also the
3770 protocol specification about the public key authentication in
3771 the connection authentication protocol. The actual data to be
3772 signed is now computed with a hash function before signing.
3774 * Fixed the public key authentication from the server as well.
3775 Affected file silcd/protocol.c.
3777 * Removed the mlock()'s from the memory allocation routines.
3778 Affected file lib/silcutil/silcmemory.c. The ./configure does
3779 not check anymore for the mlock(). Affected file is
3782 * Fixed USERS command in server to allow the execution of the
3783 command for private and secret channels if the client sending
3784 the command is on the channel. Affected file silcd/command.c.
3786 * Fixed silc_client_get_clients_local to return the clients
3787 count correctly. It could return wrong value. Affected file
3788 lib/silcclient/idlist.c.
3790 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3792 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3793 types. The assembler optimizations seemed not to like 64-bit
3794 data types. The assmebler optimizations thus are now enabled
3795 also for BSD systems as opposed to only enable them for Linux.
3797 * Do not check for threads at all on BSD systems. Affected
3798 file configure.in.pre.
3800 * Removed -n and -h options from the Irssi SILC Client since
3801 they are not used in silc.
3803 * Fixed the prime generation to assure that the first digit
3804 of the generated random number is not zero since our conversion
3805 routines does not like number strings that starts with zero
3806 digit. If zero digit is seen the random number is regenerated.
3807 This caused some corrupted RSA keys when the zero first digit
3808 was met. Affected file lib/silcmath/silcprimegen.c.
3810 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Fixed WIN32 configuration in the ./configure script.
3813 Fixed to include xti.h on environments that has it.
3814 Patches by Carsten Ilchmann and andrew.
3816 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Changed the silc_id_create_client_id to be collision
3819 resistant. It is now assured that there cannot be created
3820 two same client ID's. I suspect that some weird bugs in
3821 the server were actually caused by duplicate Client IDs.
3822 Affected file silcd/serverid.[ch]. A router receiving
3823 new ID now also assures and informs the sending server
3824 if the ID caused collision.
3826 * Changed the silc_id_create_channel_id to also assure that
3827 there are no collisions.
3829 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Statement about ignoring the Mutual Authentication flag when
3832 performing rekey with PFS was a bit misleading. It is ignored
3833 if it was set in the initial negotiation, it cannot be even
3834 set in the rekey. Fixed in the ke-auth draft. Started the
3835 new versions of the protocol drafts in the doc/.
3837 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Fixed a bug in silc_client_command_identify_save when saving
3840 new channel information. The channel name was no duplicated
3841 and caused crash on exit. Affected file is
3842 lib/silcclient/command_reply.c.
3844 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * Fixed the getkey command handling in the server. Send just
3847 empty OK reply to the sender if the key could not be fetched
3848 (but everything else was ok, like the key just was not available).
3849 Changed the public key parameter to optional in the protocol
3850 specs so that empty OK reply can be sent. Affected file
3853 Added a message to Irssi SILC client to tell to user if the
3854 server did not return a public key.
3856 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * Fixed a channel key regeneration bug. It registered new
3859 timeout tasks exponentially until all system resources were
3860 used. Affected file silcd/server.c.
3862 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Added the SILC Document generator to the scripts/silcdoc.
3865 It can be used to generate the Toolkit Reference Manual out
3866 of the source tree. Internally it will also use the RoboDoc
3867 generator now imported in util/robodoc.
3869 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Added couple of return's in rekey protocol if error orccurred
3872 during the protocol. The execution must be terminated.
3873 Affected file silcd/protocol.c. Also, terminate the protocol
3874 always with timeout.
3876 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3878 * The client's Client ID was created initally from the wrong
3879 nickname (it could have been in format nick@host) in the
3880 silc_server_new_client. Affected file silcd/packet_receive.c
3882 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Added some SILC_LOG_ERROR's to various error conditions
3885 if client could not be added to ID cache. Affected files
3886 silcd/packet_receive.c and silcd/server.c.
3888 * When client's sock->user_data is freed, NULL also the
3889 client->router and client->connection pointers. Added check
3890 for these pointers being NULL to various places around the
3891 code. Affected file silcd/server.c.
3893 * Added client->data.registered == TRUE checks to various
3894 places around the code to assure that unregistered client's
3895 are not handled when it is not allowed. Affected file
3898 * Added `bool registered' fields to all
3899 silc_idlist_[server|client]_get_* routines to indicate whether
3900 the fetched client needs to be registered or not. Affected
3901 file silcd/idlist.[ch].
3903 * Add your own entry as registered to the ID cache in the
3904 server. Affected file server.c.
3906 * Fixed a bug in silc_server_new_server. The SilcServer was
3907 set as the new server's context instead of SilcServerEntry.
3908 This naturally caused some weird bugs.
3910 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3912 * Do not delete the channel rekey task when adding it
3913 for in silc_server_create_channel_key.
3915 * Changed the silc_server_create_channel_key to return
3916 TRUE or FALSE to indicate the success of the channel key
3919 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Fixed MSVC++ project files and added missing files to
3922 Makefiles under win32/.
3924 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Do not add TCP_NODELAY flag if the operating system
3927 does not have it defined. Affected files are
3928 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3930 * Fixed buffer overflow from Irssi SILC Client. Affected
3931 file irssi/src/fe-common/core/themes.c.
3933 * Fixed double free in client library in the file
3934 lib/silcclient/client.c when disconnecting from server.
3936 * Applied double free patch from cras to Irssi SILC client.
3937 Affected files irssi/src/core/[modules/expandos].c
3939 * Fixed the disconnection handling to Irssi SILC Client.
3940 The application must call silc_client_close_connection
3941 in ops->connect client operation in case of failure of
3942 the connection. Affected file is
3943 irssi/src/silc/core/client_ops.c.
3945 * Do not set sock->protocol to NULL in the function
3946 silc_client_close_connection after executing the protocol's
3947 final callback since the sock might not be valid anymore.
3948 Affected file lib/silcclient/client.c.
3950 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Do not enable SILC_THREADS if the linking with libpthread
3953 did not happen. Affected file configure.in.pre.
3955 * Added notion to protocol specification that server must
3956 verify the sent authentication payload with CMODE when
3957 setting the channel founder key. Implemented it to the
3958 server. Affected file silcd/command.c.
3960 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Added _EXTRA_DIST SILC distribution variable to the
3963 distributions file. It is used to conditionally add extra
3964 files or directories to the specific distribution. Affected
3965 files ./prepare, Makefile.am.pre and distributions.
3967 Removed the `_' from the start of the distribution names.
3970 * Added README.WIN32 for instructions to compile the Toolkit
3973 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3975 * Fixed a double free in disconnection in the server. Affected
3976 file is silcd/server.c.
3978 * Fixed the lib/silcske/groups.c to work now also with GMP
3979 MP library. The string conversion did not work when using
3980 specific base and the base is indicated in the string as well.
3982 * Created win32/ directory which now includes MSVC++ specific
3983 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3984 It will appear only in the toolkit distribution
3986 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3988 * Changed the key material distribution function in case when
3989 the hash output is too short. The data is now concatenated
3990 a bit differently than it used to. Made the change to the
3991 SKE protocol specification.
3993 * Added better GMP detection to configure.in.pre. A patch
3996 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Fixed a minor bug in SKE that might cause some problem on
3999 some platforms. Affected file lib/silcske/silcske.c.
4001 * Added the cookie checking for initiator in the SKE. It checks
4002 that the responder returns the sent cookie unmodified. The
4003 affected file is lib/silcske/silcske.c. Added new SKE
4004 error type INVALID_COOKIE that can be sent during the
4005 negotiation. Fixed some memory leaks as well.
4007 * Added the "invalid cookie" error message to Irssi SILC client's
4010 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Added `task_max' field to the SilcClientParams to indicate
4013 the maximum tasks the scheduler can handle. If set to zero,
4014 default values are used. Affected file lib/silcclient/silcapi.h.
4016 * Fixed memory leaks in silc_client_close_connection. Affected
4017 file lib/silcclient/client.c.
4019 * Added silc_client_del_client_entry to client library to free
4020 all memory of given client entry. Affected file is
4021 lib/silcclient/idlist.[ch].
4023 * Added new functions silc_client_del_channel and
4024 silc_client_del_server to delete channel and server entries.
4025 Affected file lib/silcclient/[silcapi.h/idlist.c].
4027 * Removed silc_client_del_client_by_id from silcapi.h.
4029 * Fixed the INFO command to return the server's own info
4030 correctly when querying by Server ID. Affected file is
4033 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Removed the non-blocking settings in WIN32 code in the
4036 silc_sock_[read/write] and added SleepEx instead. Affected
4037 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4038 of input data is now checked with FIONREAD and ioctlsocket.
4040 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Call silc_schedule_task_del_by_context in the
4043 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4044 Affected file lib/silccore/silcprotocol.c.
4046 * Call silc_protocol_cancel for active protocols in the
4047 silc_server_close_connection if the funtion
4048 silc_server_free_sock_user_data has not been called.
4049 Affected file silcd/server.c.
4051 * Generic tasks cannot be deleted using the del_by_fd
4052 task deleting function since generic tasks does not match
4053 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4055 * Added a notion to SILCOPER help file that the SILCOPER works
4056 only on router server, not on normal server.
4058 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * Added for WIN32 support for the new scheduler as well.
4061 Affected file lib/silcutil/win32/silcwin32schedule.c.
4063 * Fixed the SHA1 implementation to work on various platforms.
4065 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4068 API. It is part of the scheduler now. Everything else is
4069 as previously but some functions has changed their names.
4070 Checkout the lib/silcutil/silcschedule.h for the interface.
4071 Updated all applications to use the new interface. Affected
4072 files are lib/silcutil/silcschedule.[ch].
4074 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4076 * Found a bug in the SKE implementation. The HASH value,
4077 specified by the protocol, was not computed correctly. The
4078 public key of the responder was not added to the computation
4079 even though it is mandatory. Affected file lib/silcske/silcske.c.
4080 This unfortunately causes incompatibilities with older
4081 clients and servers.
4083 * Added WIN32 specific network init and uninit functions:
4084 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4085 the Winsock2. Affected file lib/silcutil/silcnet.h and
4086 lib/silcutil/win32/silcwin32net.c.
4088 * Set the socket always to nonblocking mode on WIN32 after
4089 reading data or writing data. Affected file is
4090 lib/silcutil/win32/silcwin32sockconn.c.
4092 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4094 * Fixed various compilation problems under WIN32. Affected
4095 files lib/silcutil/win32/silcwin32thread.c and
4096 lib/silcutil/win32/silcwin32schedule.c.
4098 * Removed all _internal.h #includes from public header
4099 files. Internal headers must never be included from
4102 Removed also the lib/silcske/payload_internal.h file.
4104 * All include files that may be needed (public and some others
4105 included by the public headers) by application developers are
4106 now copied to the ./includes directory. It does not copy any
4107 internal headers. Affected file Makefile.defines.pre and all
4108 Makefile.am's under lib/ and subdirs.
4110 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4112 * Do not change the ~/.silc directory's permissions automatically.
4113 Affected file irssi/src/silc/core/clientutil.c.
4115 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Do not cancel the protocol in silc_server_close_connection
4118 it might cause recursion. Now cancelled in the function
4119 silc_server_free_sock_user_data. Affected file silcd/server.c.
4121 * Fixed the silc_server_remove_clients_by_server to regenerate
4122 the channel keys correctly finally. Added also new function
4123 silc_server_remove_clients_channels to actually do it.
4124 Affected file silcd/server.c.
4126 * Fixed the silc_server_new_channel to not crash by giving
4127 wrong router to the new channel. Affected file is
4128 silcd/packet_receive.c.
4130 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4133 which is given as argument to the silc_client_alloc now.
4134 It can be used to configure the client and set various parameters
4135 that affect the function of the client.
4137 * The USERS command in server did not check whether the channel
4138 is private or secret. Affected file silcd/command.c.
4140 * Added new argument to the USERS command in protocol specification.
4141 The USERS command now can take the channel name as argument
4142 as well. Added support for this in client and server and
4143 updated the protocol specs.
4145 * Completed the GETKEY command in client. It can be now used
4146 to fetch also servers public key not only some clients.
4147 Affected files lib/silcclient/command[_reply].c.
4149 * Added silc_client_get_server to return server entry by the
4150 server name. Affected files lib/silcclient/silcapi.h and
4153 * Redefined the IDENTIFY command in protocol specification to be
4154 more generic. It now can be used to query information about
4155 any entity in the SILC Network, including clients, servers and
4156 channels. The query may be based either the entity's name
4157 or the ID. Added support for this in both client and server.
4159 Affected files silcd/command.c and lib/silcclient/command.c
4160 and command_reply.c.
4162 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4163 the _from_client and _from_server functions. Affected file
4166 * Added silc_client_get_channel_by_id_resolve to the file
4167 lib/silcclient/silcapi.h to resolve channel information by
4168 its ID. Added also silc_client_get_channel_by_id that
4169 does not resolve it from the server.
4171 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * Added SilcServerEntry context into the client library
4174 to represent one server. The INFO command now allocates
4175 these to save the resolved server info. For now on the
4176 client library will also keep information about servers,
4177 connected and resolved with INFO.
4179 The INFO command now allocates the SilcServerEntry context
4180 and saves the server info there. The COMMAND_REPLY in
4181 the INFO now returns the parameters to application in
4182 same order as defined in the protocol specification.
4184 The entries are cached in the client->server_cache.
4186 * The INFO command is now issued after received the Client ID
4187 from the server. Affected file lib/silcclient/client.c.
4189 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4190 to the application as the mode changer might be server.
4191 It is guaranteed that NULL is not returned anymore to the
4192 application. Affected file lib/silcclient/client_notify.c.
4194 The ID Type is now also passed to the application so that
4195 it can check whether the returned entry is SilcClientEntry
4198 Added new function silc_client_get_server_by_id to return
4199 the server entry by ID. Affected files are the
4200 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4202 * Do not create the channel in the Irssi SILC Client when issuing
4203 the JOIN command but when received the sucessful JOIN command
4204 reply. Otherwise the channel might get created even though we
4205 could not join it. The Affected file is
4206 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4208 * Fixed a channel joining bug in router. The router must also
4209 check the channel modes, invite and ban lists etc. when serving
4210 the JOIN command sent by normal server. Affected file is
4211 silcd/command.c. The router now resolves the client's
4212 information from the server who sent the JOIN command if it
4213 does not know it, and processes the JOIN command only after
4216 * Changed the SilcCommandCb to take new argument; void *context2.
4217 Affected file lib/silccore/silccommand.h
4219 The second argument in the command callbacks in the server now
4220 includes the SilcServerCommandReplyContext if the command was
4221 called as pending command callback from the command reply.
4222 Otherwise it is NULL. When called as pending the status of the
4223 command reply will be checked and if it was erronous the
4224 error will be sent to the original sender of the command.
4225 This way the client always receives the error messages even
4226 though the server was actually the one who received the error
4227 when it resent the command to router, for example. Affected
4228 files silcd/command[_reply].[ch].
4230 * Fixed sending WHOWAS command's error message to client if
4231 the requested client could not be found. It was missing.
4234 * Changed the CMODE and CUMODE commands reply arguments in the
4235 protocol specification. The Channel ID is now sent in both
4236 of the commands to identify the channel. Implemented this
4237 new feature to the client and server. Affected files
4238 lib/silcclient/command_reply.c and silcd/command.c.
4240 * Made better checks for invite and ban lists in the JOIN
4241 command in server. Affected file silcd/command.c.
4243 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4245 * The server now performs the incoming host IP/DNS lookup
4246 using the silc_socket_host_lookup and thus does not block
4247 the server anymore. Affected file silcd/server.c.
4249 * Completed the multi-thread support for SILC Scheduler in
4250 the lib/silcutil/silcschedule.c.
4252 * Fixed the configure.in.pre to detect the pthread correctly
4255 * Fixed a deadlock in silc_task_queue_wakeup in the file
4256 lib/silcutil/silctask.c.
4258 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Added new function silc_schedule_wakeup that is used in
4261 multi-threaded environment to wakeup the main thread's
4262 schduler. It needs to be used when a thread adds a new task
4263 or removes a task from task queues. After waking up, the
4264 scheduler will detect the task queue changes. If threads
4265 support is not compiled in this function has no effect.
4266 Implemented the wakeup mechanism to both Unix and WIN32
4267 systems. Affected files are lib/silcutil/silcschedule.[ch],
4268 lib/silcutil/unix/silcunixschedule.c and the
4269 lib/silcutil/win32/silcwin32schedule.c.
4271 * Added new function silc_task_queue_wakeup to wakeup the
4272 scheduler by the specified task queue. Affected file
4273 lib/silcutil/silctask.[ch].
4275 * The silc_socket_host_lookup_start now wakes up the scheduler
4276 after adding the timeout task. Affected file is
4277 lib/silcutil/silcsockconn.c.
4279 * The silc_socket_host_lookup is synchronous now if the threads
4280 support is not compiled in. However, the callback is still
4281 called asyncronously through the scheduler, anyway. Affected
4282 file lib/silcutil/silcsockconn.c.
4284 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4286 * Added new function silc_socket_host_lookup to perform
4287 asynchronous IP and FQDN lookups for the socket connection.
4288 Affected files lib/silcutil/silcsockconn.[ch].
4290 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4293 that may or may not compile the mutex support in.
4295 Changed the silc_mutex_alloc interface. It allocates the
4296 mutex now to the sent pointer and returns TRUE or FALSE.
4298 Affected file lib/silcutil/silcmutex.h.
4300 * Wrote the SILC Task Queue interface to support multi-threads.
4301 Affected file lib/silcutil/silctask.[ch].
4303 * Wrote the SILC Scheduler to support multi-threads. Affected
4304 file lib/silcutil/silcschedule.c.
4306 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4308 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4309 in lib/silcutil/win32/.
4311 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4313 * Defined SILC Mutex API and SILC Thread API and implemented
4314 them for Unix. Affected files are
4315 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4316 lib/silcutil/unix/silcunixmutex.c and
4317 lib/silcutil/unix/silcunixthread.c.
4319 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4321 * Fixed the silc_server_remove_clients_by_server's channel
4322 key re-generation. The hash table handling was incorrect
4323 and would not work with many channels. Affected file is
4326 * Fixed some memory leaks around the server code.
4328 * Rewrote the silc_server_get_users_on_channel to support IPv6
4329 based Client ID's. Affected file silcd/server.c.
4331 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4332 specification. However, a separate document must be written
4333 to define the detailed signing procedure and the payload
4334 associated with the flag. Defined the flag to the
4335 lib/silccore/silcchannel.h as well.
4337 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Changed the dynamic tables to static size tables in the
4340 lib/silccrypt/silchmac.c.
4342 * Removed GCC dependencies from the code. A patch by cras.
4344 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4346 * Do not show the error "Error receiving packet bla bla"
4347 in server if it really was not an error (-2 means that reading
4348 is pending). Affected file silcd/server.c.
4350 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4352 * Fixed a possible crash in silc_server_remove_clients_by_server
4353 in silcd/server.c. Fixed there also some memory leaks.
4355 * Fixed the silc_idlist_replace_client_id. It could replace
4356 wrong key in the hash table. Affected file silcd/idlist.c.
4358 * Do not check whether there are global users on the channel
4359 if the channel->global_users is FALSE. Affected functions
4360 silc_server_remove_from_one_channel and
4361 silc_server_remove_from_channels in silcd/server.c. Also,
4362 do not check if the removed client is local as we can be
4363 sure that global client was not removed from the channel
4364 and checking for global users is not needed.
4366 * The silc_server_remove_clients_by_server now re-generates
4367 the channel keys correctly for those channels that had
4368 clients removed from them. Affected file silcd/server.c.
4370 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * Found the reason of random crashes in the server. We weren't
4373 ignoring the SIGPIPE signal (which can be sent in write())
4374 and it crashed the server. Affected file silcd/silcd.c.
4376 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4378 * Assure that sock->user_data is not NULL in the function
4379 silc_server_packet_send in silcd/packet_send.c.
4381 * Disconnect the remote connection if it could not be added
4382 to any ID lists in the server. The affected file is
4385 * Check in silc_server_packet_send[_real/dest] that the
4386 socket is not disconnecting and ignore the data if it is.
4387 Affected file silcd/packet_send.c.
4389 * Define inline to __inline on native WIN32 compilation.
4390 Affected file includes/silcwin32.h.
4392 * Added some explicit type casts for inline code since MSVC
4393 require them. Affected files lib/silcutil/silcbuffer.h,
4394 lib/trq/silcdlist.h and lib/trq/silclist.h.
4396 * Print warning in log files from now on if the packet
4397 decryption fails. Affected file silcd/server.c.
4399 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4401 * Changed the `say' client operation's interface to accept
4402 new `type' argument to indicate the type of the message sent
4403 by the library. The application may filter the library's
4404 messages according the type. The affected file is the
4405 lib/silcclient/silcapi.h.
4407 * Added two new functions to lib/silcclient/silcapi.h:
4408 silc_client_del_client and silc_client_del_client_by_id.
4409 Affected file lib/silcclient/idlist.c.
4411 * Moved the clientincludes.h from includes/ to silc/ and
4412 serverincludes.h from includes/ to silcd/.
4414 * The modes for the CMODE and CUMODE are now passed as
4415 uint32 for application with COMMAND_REPLY. The affected
4416 file is lib/silcclient/command_reply.c.
4418 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4420 * /WHOIS without arguments shows client's own information.
4421 Affected file lib/silcclient/command.c.
4423 * Changed PING to not accept any arguments. The specs
4424 says that client can ping only the connected server so
4425 requiring an argument is not needed. Affected file is
4426 lib/silcclient/command.c.
4428 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4430 * Fixed a fatal bug in private message sending and reception
4431 encryption and decryption when using private message keys.
4432 The implementation was incorrect and did not follow the
4433 specification. It causd that some of the message were
4434 lost since it did not use the sending and receiving keys
4435 as the protocol suggests. This has been fixed and will cause
4436 incompatibilities with older clients when sending private
4437 message encrypted with private message keys. Affected files
4438 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4439 and various other in Irssi SILC Client.
4441 Added `responder' boolean argument to the functions
4442 silc_client_add_private_message_key[_ske] to indicate when
4443 the key is added as responder or initiator of the key
4446 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4448 * Removed the silc_ske_check_version function and created
4449 a SilcSKECheckVersion callback. Added also a function
4450 silc_ske_set_callbacks that is now used to set all SKE
4451 callbacks. The callback functions are not given to
4452 the SKE functions anymore, but this function is used to
4455 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4457 * Added `silc_version' argument to the silc_client_alloc
4458 to define the version of the application for the library.
4459 The library will use the version string to compare it
4460 against the remote host's (usually a server) version
4461 string. Affected file lib/silcclient/silcapi.h
4463 * Added the KE protocol context to Key Agreement context
4464 in client library so that we can abort the SKE if it
4465 is in process when we get timeout. Affected file is
4466 lib/silcclient/client_keyagr.c.
4468 * Do not resolve the client ID forever if it returns in the
4469 first time that such client does not exist. This was done
4470 for example with private message. Affected file is
4471 lib/silcclient/client_prvmsg.c.
4473 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4475 * Do not add regex.h for WIN32. The affected file
4476 includes/silcincludes.h.
4478 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4479 not work yet 100%. It generates the DLL's automatically
4480 when compiling with --with-win32 under cygwin.
4482 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4484 * lib/contrib/regex.c is not compiled on WIN32.
4486 * Added silc_net_get_socket_opt function to the
4487 lib/silcutil/silcnet.h.
4489 * Added includes/silcwin32.h for WIN32 specific includes
4492 * Do not use ptime structure or any of the posix process
4493 functions on WIN32 in lib/silccrypt/silrng.c.
4495 * Added silc_gettimeofday to provide generic function
4496 for struct timeval on all platforms. Added the function
4497 to lib/silcutil/silcutil.h.
4499 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4501 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4502 library as they clearly belong there. As a plus side we
4503 can make the actual socket connection routines platform
4506 Added also new generic function silc_socket_read and
4507 silc_socket_write (that used to be silc_packet_[read/write].
4508 The implementation of these are platform specific.
4510 * Added WIN32 specific routines of silc_socket_[read/write]
4511 to lib/silcutil/win32/silcwin32sockconn.c.
4513 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4515 * Added preliminary support for native WIN32 compilation under
4516 cygwin (using the -mno-cygwin option for GCC) to the
4517 ./configure.in.pre. The --with-win32 now prepares the
4518 compilation for native WIN32.
4520 * Rewrote the SILC Scheduler interface in the file
4521 lib/silcutil/silcschedule.h. The scheduler is now context
4522 based and does not have anymore any global static scheduler.
4523 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4524 and created lib/silcutil/win32 directory for WIN32 based
4527 * Added Unix specific network routines to the
4528 lib/silcutil/unix/silcunixnet.c and the old
4529 lib/silcutil/silcnet.c includes now only generic routines.
4531 Added WIN32 specific network routines to the
4532 lib/silcutil/win32/silcwin32net.c.
4534 * Added Unix specific utility functions from the
4535 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4537 * Added WIN32 SILC Scheduler to the file
4538 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4541 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4543 * Do not handle JOIN notify in the server if the target client
4544 is not registered (idata->registered == FALSE). The affected
4545 file is silcd/packet_receive.c.
4547 * Update the nickrec->founder in event_cumode in the Irssi SILC
4548 client. Affected file irssi/src/silc/core/silc-channels.c.
4550 * Fixed the CUMODE_CHANGE notify handling in the server when
4551 server and router are announcing their clients on channels.
4552 Now the mode changes are saved and notified correctly. The
4553 affected file is /silcd/packet_receive.c.
4555 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4556 They really did not replace the cache entry in the ID Cache.
4557 Now they do that. Affected file silcd/idlist.c.
4559 * Fixed the KICK notify handling in the Irssi SILC client to
4560 update the channel records so that the kicked client does not
4561 appear to be on the channel. The affected file is
4562 irssi/src/silc/core/silc-channels.c.
4564 * Always update the conn->current_channel when executing command
4565 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4567 * Fixed the KILL notify handling in Irssi SILC client to remove
4568 the killed client on all channels.
4570 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Fixed the silc_parse_command_line to remove extra spaces
4573 from the start and end of the arguments. Affected file is
4574 lib/silcutil/silcutil.c.
4576 * Cancel and free any active protocol in the function
4577 silc_server_close_connection. Affected file silcd/server.c.
4579 * Cancel and free any active protocol in the function
4580 silc_client_close_connction. Affected file is
4581 lib/silcclient/client.c.
4583 * Do not execute the KILL command for clients that are in
4584 history (ie. they are not in the network). Affected file is
4587 * Fixed KILL notify handling, client does not crash anymore.
4588 Affected file irssi/src/silc/core/silc-channels.c.
4590 * Reduced the default packet buffer size from 2048 to 1024 in
4591 lib/silccore/silcpacket.c.
4593 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4594 counter to the SKE context that is incresed when the SKE library
4595 performs async operation outside the library. If the outside
4596 process frees the SKE context and FREED status will be set
4597 and the library will detect after the sync operation that the
4598 libary is freed. The affected files are
4599 lib/silcske/silcske[_status].[ch].
4601 * Resolve the client entry information in the function
4602 silc_client_channel_message to assure that NULL pointer is not
4603 passed as client entry to the application. */
4605 * Fixed the task timeout calculation to assure that there is
4606 never negative timeouts. The affected file is
4607 lib/silcutil/silcschedule.c.
4609 * Fixed the channel user mode notification sending in server.
4610 It was sent point-to-point to the router (or to server by router)
4611 but it needs to be destined to a channel. The routines now
4612 supports sending the channel user mode notifys to the channels
4613 when announcing clients and channels. Affected files are
4614 silcd/server.c and silcd/packet_receive.c.
4616 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4617 It did not actually replace the old channel entry in the cache.
4618 Affected file lib/silcclient/client_notify.c.
4620 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Fixed a possible crash in silc_packet_send_prepare. It now
4623 assures always that there is enough space in the buffer and
4624 at the tail area of the buffer (for MAC).
4626 Fixed the inbound buffer reallocation in silc_packet_read.
4627 It was old code and did not handle the reallocation correctly.
4630 The affected file is lib/silccore/silcpacket.c.
4632 * Fixed buffer overflow in silc_parse_nickname in the file
4633 lib/silcutil/silcutil.c.
4635 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * make install generates new server keys only if there is not
4640 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4643 Added check that if the NOREPLY is set then we will not send
4644 the away message. This avoids infinite loop of away messages
4645 if both clients are away. The affected file is
4646 lib/silcclient/client_prvmsg.c.
4648 * Fixed client crash if /NICK was given without arguments.
4649 Affected file lib/silcclient/command.c.
4651 * Server does not send the invite list in INVITE command back
4652 to the client if the list was not altered. Added this notion
4653 to the protocol spec as well. Affected file silcd/command.c.
4655 Fixed possible crash in INVITE command by checking the
4656 value of silc_server_get_client_route command.
4658 * Fixed the INVITE notify type handling. The arguments are now
4659 taken in correct order and client does not crash. The affected
4660 file is irssi/src/silc/core/silc-channels.c.
4662 Removed the "Inviting xxx to channel" message from the
4663 client library away and let the application handle it.
4664 Affected file lib/silcclient/command.c. Added that message
4665 to Irssi SILC client's message formats.
4667 * Fixed CMODE command crash in client. It now checks the
4668 amount of arguments correctly and does not crash. The affected
4669 file is lib/silcclient/command.c.
4671 * Do not create new channel automatically in silc_channels_join
4672 but check whether the channel by that name already exists.
4673 Affected file irssi/silc/core/silc-channels.c.
4675 * Do not send the SERVER_SIGNOFF to router if the disconnected
4676 entity was the router. Affected file silcd/server.c.
4678 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4679 SILC client as it was missing from there.
4681 Added the handling of the KICK notify to the Irssi SILC client
4682 as it was missing. Added "you have been kicked" message to
4683 Irssi SILC client's message modules formats.
4685 Added the handing of the KILL notify to the Irssi SILC client
4686 as it was missing. Added the kill message module formats
4689 The affected file is irssi/src/silc/core/silc-channels.c.
4691 * The router did not save the channel mode the server announced.
4692 Affected file silcd/packet_receive.c.
4694 * Fixed a possible crash in INFO command in server. If the
4695 server did not provide the server info it crashed. Affected
4696 file silcd/command.c.
4698 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Fixed the GETKEY command in the server to check also the
4701 global list. Otherwise the GETKEY would not work correctly
4702 in normal SILC server. Affected file silcd/command.c.
4704 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Fixed GETKEY crash, it crashed if the command did not succseed.
4708 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4711 is now real and not just an macro interface to GMP.
4713 Removed the entire GMP from the source tree and imported new
4714 NSS MPI library instead. Reason for removing GMP is that it is
4715 extremely large and compiles extremely slow. The NSS MPI
4716 is only a few files and compiles in less than 10 seconds.
4717 The speed is also about the same as GMP. The MPI is imported
4718 to lib/silcmath/mpi.
4720 If the system has GMP installed we will still use the GMP.
4721 If it is not then the NSS MPI will be compiled.
4723 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Merged a long nickname (127 characters long) crash bugfix from
4726 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4728 * Merged a freed memory reference bugfix from Irssi CVS tree.
4729 Affected file irssi/src/core/commands.c.
4731 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Added the server's public key sving and verification to the
4734 server when performing the SKE. This was missing and the
4735 remote server's (or router's) public key was accepted without
4736 checking whether we have it previously or trust it at all.
4737 Affected file silcd/protocol.c.
4739 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Check in the silc_server_timeout_remote if protocol is active
4742 and make sure that the protocol's final callback is called so
4743 that all memory if freed. Affected file silcd/server.c.
4745 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * silc_server_whois_send_reply crashed the server if the nickname
4748 was 127 characters long. Affected file silcd/command.c.
4750 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Added sanity check to the silc_server_new_client. If the hostname
4753 is provided inside username then check that the provided hostname
4754 really is the same as the resolved one. If the hostname was not
4755 resolved then check it from the public key. Affected file is
4756 silcd/packet_receive.c.
4758 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4759 if the server disconnected us and the connection is not valid
4760 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4762 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4763 the library to the lib/silcutil/silcutil.[ch].
4765 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Close log file after open. Affected file
4768 lib/silcutil/silclog.c.
4770 * Check whether sock == NULL in silc_client_send_packet and return
4771 if it is. Affected file lib/silcclient/silcclient.c.
4773 * Check rec->entry == NULL in the Irssi SILC Client before
4774 sending the channel message. Affecte file is
4775 irssi/src/silc/core/silc-servers.c.
4777 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Merged a splitted window bugfix from Irssi CVS tree. The
4780 affected file is irssi/src/fe-text/textbuffer-view.c.
4782 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4783 It did not print nickname.
4785 * Improved the distributions system a bit.
4787 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4790 irssi/src/fe-text/gui-window.c.
4792 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4793 to in-active server. The affected file is
4794 irssi/src/silc/core/client_ops.c.
4796 * Resolve the client in USERS command reply if the entry does
4797 not have username resolved. The affected file is
4798 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4799 command to WHOIS command to really resolve stuff. The USERS
4800 is not used any more in any critical section so WHOIS can
4801 be used even though it might be slower than IDENTIFY.
4803 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4806 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Changed the protocol API a bit more consistent in the
4809 lib/silccore/silcprotocol.[ch].
4811 * Changed the following headers to ROBODoc format:
4813 lib/silccore/silcpayload.h
4814 lib/silccore/silcprotocol.h
4815 lib/silccore/silcsockconn.h
4817 All core library headers are now formatted.
4819 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Fixed a bug in Irssi SILC client; do not show that you are
4822 server/router operator if you really are not. Affected file is
4823 irssi/src/silc/core/client_ops.c.
4825 * Renamed silc_command_free_payload to silc_command_payload_free.
4826 Affected file lib/silccore/silccommand.h
4828 * Added silcmath.h to include the prototoypes of various routines
4829 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4832 * Changed the following headers to ROBODoc format:
4834 lib/silccore/silcchannel.h
4835 lib/silccore/silccommand.h
4836 lib/silccore/silcid.h
4837 lib/silccore/silcidcache.h
4838 lib/silccore/silcmode.h
4839 lib/silccore/silcnotify.h
4840 lib/silccore/silcpacket.h
4841 lib/silcmath/silcmath.h
4843 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added checking to the server code not to start the server if
4846 ciphers and stuff are not configured properly. Affected files
4847 silcd/serverconfig.[h] and silcd/server.c.
4849 * Changed the layout of the header files of the public interfaces
4850 in the SILC libraries. The new layout supports ROBODoc
4851 documentation tool (and some others) so that it is easy to create
4852 a library reference manual. All the other headers and source
4853 code must still follow the CodingStyle document. Also source
4854 code must not include these ROBODoc stuffs, only the headers.
4855 Furthermore, all public interface headers must now be named
4856 by using `silc' prefix, example: silcapi.h, silccipher.h.
4857 Some files were renamed due to this. All the other headers
4858 must not be used as public interfaces. I will update the
4859 CodingStyle document later. Changed following headers, so far:
4861 lib/silcclient/silcapi.h
4862 lib/silccore/silcauth.h
4863 lib/silccore/silcprivate.h
4864 lib/silccrypt/silcdh.h
4866 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Removed silc_client_packet_send_flush from the client library
4871 as it is not needed. Affected file lib/silcclient/client.[ch].
4873 * Added printing of message of unresolved authentication method
4874 to the Irssi SILC client. Added it to the module formats.
4875 Removed the same message from the client library.
4877 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added new distribution feature, DISTLABEL. Every distribution
4880 can define own preprocessor label that can be used in the
4881 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4882 file distributions, acconfig.h.pre and prepare.
4884 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added Makefile.defines_int to include the actual definitions
4887 for Makefile.defines.in. Tested the new distribution system,
4888 created distributions and tested installation.
4890 * Added AWAY message printing to the Irssi SILC client. Added
4891 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4893 * Added SCONNECT command to call the SILC's CONNECT command.
4894 Cannot use CONNECT directly since Irssi uses that internally.
4895 Affected file irssi/src/silc/core/silc-servers.c.
4897 Added ACTION local command. It is same as ME command but takes
4898 the channel as mandatory argument.
4900 Rewrote some of the Irssi's help files to suite for SILC
4903 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added Makefile.defines[.in] that should for now on be included
4906 in all Makefile.am file in the source tree. That file includes
4907 all common compilation definitions for SILC source tree.
4909 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Minor changes to the ./prepare script to change the package
4912 name according the distribution name to the configure.in.
4914 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Created new distribution system. Added file `distributions'
4917 that defines all the distributions that can be created out of
4918 the SILC source tree. The ./prepare script now reads that
4919 file to determine how to prepare the distributions. The
4920 first argument to the ./prepare is the name of the distribution
4921 and second is the version of the distribution. If given
4922 without arguments it creates the default (toolkit) distribution
4923 with the default version (defined in ./prepare).
4925 All Makefile.am files that are subject to the distributions
4926 are now named as Makefile.am.pre. These are ./Makefile.am
4927 and lib/Makefile.am. Others may be changed later.
4929 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Added invite list, ban list, some key management and connection
4932 error message printing to module formats in the Irssi SILC client.
4934 * Added new silc_client_set_away_message to set the away message
4935 that is back to the person who sent private message. The
4936 affected file lib/silcclient/silcapi.h and the
4937 lib/silcclient/client_prvmsg.c.
4939 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Fixed the private message sending in the Irssi SILC client,
4942 added local command KEY to the Irssi SILC client.
4944 Added key management and key agreement message formats to the
4945 irssi/src/fe-common/silc/module-formats.[ch].
4947 Added USERS (alias WHO) printing, server/router operator
4948 indication and LIST command printing to the module formats.
4950 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Fixed channel joining notify handling, cumode notify handling
4953 from Irssi SILC client.
4955 * Added SILC specific module-formats to the Irssi SILC client so
4956 that SILC specific message hilighting, colors etc is possible.
4957 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4959 Added channel mode, channel user mode, actions, notices,
4960 whois and whowas printing to the the module-formats.c.
4962 * Fixed a bug in channel deletion in the server. The channel
4963 is not left to the cache even if the channel founder auth mode
4964 is set when there are no users anymore on the channel. Affected
4965 file silcd/server.c.
4967 * The silc_net_localhost now resolves the entire hostname including
4968 the domain name. Affected file lib/silcutil/silcnet.c.
4970 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Changed the ask_passphrase client operation to be ascynchronous.
4973 It has now a completion callback and a context that the
4974 application must call after it has got the passphrase from
4975 the user. Affected files lib/silcclient/silcapi.h,
4976 lib/silcclient/protocol.c, lib/silcclient/command.c and
4979 Added SilcAskPassphrase callback that the application calls
4980 to deliver the passphrase to the library.
4982 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4983 The public key verification and especially a certificate
4984 verification is asynchronous procedure.
4986 Added new SILC_SKE_STATUS_PENDING status to indicate the
4987 request is pending and a callback will be called to finalize
4990 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4991 indicate that remote end did not send its public key (or
4992 certificate), even though we require it. Added check for this
4993 condition in the SKE. This was a security bug, now fixed.
4995 Defined new SilcSKEVerifyCbCompletion callback that is called
4996 when the verification process is completed.
4998 The affected files lib/silcske/silcske_status.h and
4999 lib/silcske/silcske.[ch].
5001 * Changed the verify_public_key client operation to be async
5002 as well. Defined SilcVerifyPublicKey callback that is used to
5003 indicate the success of the public key verification process.
5005 Changed the server and client to use the new async client
5008 * Changed the Irssi SILC client's internal scheduler to be called
5009 twice as many times as it used to be. As a result the client
5010 should be a bit faster now. Affected file is
5011 irssi/src/silc/core/silc-core.c.
5013 * Added support to Irssi SILC client of asynchronous public key
5014 verification and passphrase inquiry. Affected file is
5015 irssi/src/silc/core/silc-core.c.
5017 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Do not say "You have left channel %s" in client library.
5020 Moved it to the application. Affected files are
5021 lib/silcclient/command.c and silc/client_ops.c.
5023 * Fixed silc_client_get_clients. Command context was not
5024 duplicated and was freed memory in the callback. Affected
5025 file lib/silcclient/idlist.c.
5027 * Do not say "you are now talking..." on JOIN command in the
5028 client library. The appliation must handle it.
5030 * Do not say ".. changed topic to" in command reply in the
5031 client libary. The application must handle it.
5033 * Fixed TOPIC command sending in the client library.
5035 * Fixed a memory leak in silc_client_command_free in the file
5036 lib/silcclient/command.c.
5038 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Imported a modified version of Irssi client to the source tree.
5041 The Irssi will be used to create a new client called
5042 Irssi SILC. Imported to irssi/.
5044 Added silc_core_init_finish function to the Irssi. Affected
5045 file irssi/configure.in.
5047 A lot changes in the Makefile.ams around the irssi tree.
5049 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Do not rehash if the new size is same as the old size of the
5052 hash table, in the silc_hash_table_rehash*. The affected file
5053 lib/silcutil/silchashtable.c.
5055 * Replaced hash_table_del_by_context calls from the server
5056 (when channel->user_list and client->channels) to the
5057 hash_table_del as it is sufficient and faster.
5059 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Added silc_hash_table_list, silc_hash_table_get and the
5062 SilcHashTableList structure to provide an alternative way to
5063 traverse the hash table. The affected files are
5064 lib/silcutil/silchashtable.[ch].
5066 * Changed the server's idlist routines to use the hash table
5067 routines to optimize the code.
5069 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Replaced the client entry's `channel' list and channel entry's
5072 `user_list' list to hash tables for optimized lookup. Changed
5073 the code to use the hash table interface around the code.
5074 Affected file lib/silcd/idlist.[ch].
5076 * Added `auto_rehash' boolean argument to the function
5077 silc_hash_table_alloc to indicate whether the hash table should
5078 auto-rehash when it thinks is appropriate time. It will
5079 increase the hash table size if the there is twice as much
5080 entries in the table than the size of the table, and will
5081 decrease the size if there are twice as less entries than
5082 the size of the table.
5084 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5088 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * silc_idcache_purge_by_context deletes the entry now by context
5091 as it is supposed to do. Affected file lib/silccore/idcache.c.
5093 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5094 client is not anymore valid (WHOWAS givens the info) and not
5095 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5097 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Removed the `data' and `data_len' arguments from the ID Cache
5100 interfaces and added `name' argument. ID Cache does not handle
5101 anymore the binary data only a names associated with given ID.
5103 * When hashing a Client ID with silc_hash_id the entire ID is
5104 not hashed anymore, instead only the hash of the Client ID is
5105 hashed. This way we can access the Client ID from the cache
5106 with Client ID but with the hash of the ID (which is a hash of
5107 the nickname) as well without any difference in performance.
5109 Added also silc_idcache_find_by_id_one_ext to do one on one
5110 searching when we have the actual ID. Added also function
5111 silc_hash_client_id_compare. The affected files are
5112 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5114 * When hashing the name associated with a ID it is always done
5115 in lowercase. This way we can access the cache without worrying
5116 about case-sensitivity, even though, for example nicknames are
5119 * Fixed a bug in server with channel message sending. It put
5120 wrong ID type as destination ID. The affected file
5121 silcd/packet_send.c.
5123 * silc_idcache_del_by_context now deletes from all hash tables
5124 by context. Affected file lib/silccore/idcache.c.
5126 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Changed the client library to use the new ID Cache interface.
5129 Changes around the source tree.
5131 * Added silc_hash_table_rehash_ext to rehash with specific
5132 hash function. Affected file lib/silcutil/silchashtable.[ch].
5134 * Added silc_hash_string_compare to compare two strings in the
5135 hash table. Affected file lib/silcutil/silcutil.[ch].
5137 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Added new function silc_idcache_del_by_context into the
5140 lib/silccore/idcache.[ch].
5142 * Changed the server's ID list routines to use the new ID Cache
5143 interface. Changes around the source tree.
5145 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Added silc_hash_table_del[_by_context]_ext functions in to the
5148 lib/silcutil/silchashtable.[ch].
5150 Removed silc_hash_table_find_all* routines and added new
5151 silc_hash_table_find_foreach to replace them.
5153 Added silc_hash_table_replace_ext function as extended
5154 replacing function. Separated the simple hash table interface
5155 from the extended hash table interface in the file
5156 lib/silcutil/silchashtable.h.
5158 * Fixed minor bugs and changed it to use some of the new
5159 hash table functions in lib/silccore/idcache.c
5161 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Added new function silc_hash_table_find_all to return all keys
5164 in the hash table by the specified key. As the hash table is
5165 collision resistant it also makes it possible to have several
5166 duplicate keys in the hash table. This function may be used to
5167 find all of the keys from the hash.
5169 Added user_context arguments to the SilcHashFunction,
5170 SilcHashCompare and SilcHashDestructor to deliver user specified
5173 Added new fuctions silc_hash_table_find[_all]_ext to do
5174 extended lookup with specified hash and compare functions and
5175 specified user contexts.
5177 Added new function silc_hash_table_add_ext to add the key
5178 with specified hash function and user context.
5180 Added new function silc_hash_table_foreach to traverse all
5181 entrys in the hash table. Added SilcHashForeach callback
5184 Added new function silc_hash_table_del_by_context to delete
5185 the entry only if the context associated with the key matches.
5187 Affected files are lib/silcutil/silchashtable.[ch].
5189 * Removed silc_hash_[server/client/channel]_id and added just
5190 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5191 silc_hash_id_compare to compare two ID's using as the hash table
5192 comparison function. Added also silc_hash_data to hash
5193 binary data and silc_hash_data_compare to compare it.
5195 * Removed silc_idlist_find_client_by_hash as it is not needed
5196 anymore. Affected file silcd/idlist.[ch].
5198 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5199 to use internally the SilcHashTable. The new ID Cache is a lot
5200 faster than the old one. Some of the ID Cache interface was also
5201 rewritten and obsolete and stupid functions were removed.
5203 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Added entry_count field to the SilcHashTable to keep the number
5206 of the entries in the table. Implemented the function
5207 silc_hash_table_rehash. Added new function
5208 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5210 Fixed a minor bug in silc_hash_table_free.
5212 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5213 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5214 into the lib/silcutil/silcutil.[ch].
5216 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Implemented a collision resistant hash table into the
5219 lib/silcutil/silchashtable[ch]. See the header and the source
5220 for the SilcHashTable API.
5222 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Merged dotconf version 1.0.2 into lib/dotconf.
5226 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Do not compile anything in lib/silcsim/* if the SIM support
5229 is not enabled. The tree should now compile without problems
5232 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Compiled the SILC under cygwin. Compiled and tested briefly
5235 without problems. More tests needed. The SIMs didn't compile
5238 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5240 * Fixed possible crash in silc_get_username in the
5241 lib/silcutil/silcutil.c.
5243 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Fixed a va_arg in silc/client_ops.c.
5247 * Oops, RC5 routines were named AES and caused some problems
5248 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5250 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added new SilcIDIP structure into the lib/silccore/id.h and
5253 replaced the old `ip' fields from all SILC ID's to that type.
5254 This is a step towards IPv6 support.
5256 The silc_id_get_len takes now the ID as an extra argument.
5257 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5258 both IPv4 and IPv6 based ID's.
5260 The affected files are lib/silccore/id.[ch] and other files
5261 around the tree using these routines.
5263 * Removed the ID length arguments in server from various
5264 silc_server_send_notify_* routines -> they are not needed
5267 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Fixed memory leak in silc_encode_pem_file in the file
5270 lib/silcutil/silcutil.c.
5272 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Check minor version as well in the SKE. Affected files are
5275 silcd/protocol.c and lib/silcclient/protocol.c.
5277 * Added --identifier option to the server so that an identifier
5278 can be when creating the public key for the server. Affected
5279 file is silcd/silcd.c.
5281 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5282 lib/silccrypt/silcpkcs.c.
5284 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Register default ciphers and stuff when using -C option with
5287 the server. Affected file sildc/silcd.c.
5289 * Put back the servers public key filename format, it is better
5290 than the new one. For now, the client keys are saved with the
5291 new filename format. The affected file silc/client_ops.c.
5293 * Implemented the Cipher API for the rest of the ciphers that
5294 did not implement it or implemented it the wrong way.
5296 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Register default ciphers and stuff when using the -S option
5299 in the client. Affected file silc/silc.c. Same also when
5300 creating new key pair with -C option.
5302 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Fixed the silc_verify_public_key client operation function to
5305 save the public keys differently. The fingerprint is now
5306 used as filename and not the hostname. This way also the
5307 client keys are saved uniquely and not with hostnames. The
5308 affected file is silc/client_ops.c.
5310 * Trimmed the silc_hash_fingerprint function to remove extra
5311 whitespaces from the end of the fingerprint. The affected
5312 file is lib/silccrypt/silchash.c.
5316 * Added silc_cipher_register_default function to register all
5317 default ciphers. It can be used when configuration files
5318 does not exist and the application does not want any specific
5319 ciphers in any specific order.
5321 The SilcDList is now used as silc_cipher_list dynamically
5322 allocated cipher list. Removed the static list all together
5323 and now all ciphers must be allocated to the dynamic list.
5324 The silc_cipher_alloc routine was changed to check only the
5327 All silc_cipher_* routines that used to return int returns
5330 The affected files lib/silccrypt/silccrypt.[ch].
5332 * The same thing was done to silc_hash_* as for silc_cipher_*
5333 routines. Affected files lib/silccrypt/silchash.[ch].
5335 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5336 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5337 Added also silc_pkcs_[un]register[_default] functions.
5338 Removed the data_context from the PKCS API.
5340 * Added silc_hmac_register_default function to register default
5341 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5342 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5343 to unregister all hmacs at once.
5345 * Register the default ciphers, hash functions, PKCSs and HMACs
5346 if client's configuration file does not exist. The affected
5349 * The client did not load the hash functions from the SIM
5350 modules at all. Added support for this. Affected file is
5351 silc/clientconfig.c.
5353 * When decoding public key with silc_pkcs_public_key_decode, check
5354 the supported algorithm only if PKCS are registered. Affected
5355 file lib/silccrypt/silcpkcs.c. The same was done with the
5356 silc_pkcs_private_key_decode.
5358 * Fixed the SILC List routines to keep the list always in order.
5359 It used to change the list's order when traversing the list but
5360 not it preserves the order. Affected file lib/trq/silclist.h.
5362 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Added the client library to use the SilcSocketConnection's
5365 reference counter (by silc_socket_dup) to prevent the bug that
5366 the socket object may be freed underneath async operation.
5368 * The name resolv library checking fixes in the configure.in.pre.
5371 * Created new version of the protocol drafts for future
5372 development. The -03 drafts are the ones that will be changed
5373 in the trunk now and the -02 will remain as they are.
5375 * Send list of CUMODE notifys to the router when announcing
5376 the channel users to the router. Affected file silcd/server.c.
5377 If the router receiving channel founder CUMODE for a channel
5378 that already has channel founder it will send CUMODE notify
5379 to the sender to remove the channel founder rights from the
5380 announced client. Affected file silcd/packet_receive.c.
5382 * The CUMODE notify may now use Server ID as well as the entity
5383 who changes the mode. Updated protocool specs.
5385 * Updated INSTALL and README files.
5387 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * New web pages in the http://silc.pspt.fi. The pages was
5394 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Implemented the [DenyConnectin] config section in the server.
5397 Added silc_server_config_denied_conn to check whether incoming
5398 connection is denied. Affected file silcd/serverconfig.[ch].
5400 * Do not check the ports when checking the incoming configuration
5401 data if the port is 0, meaning any. Affected file is
5402 silcd/serverconfig.c.
5404 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Fixed buffer overflow in silc_string_compare in the file
5407 lib/silcutil/silcutil.c.
5409 * Fixed double free in silc_server_command_leave in the file
5412 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Fixed the version checking in the server. Affected file is
5417 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Fixed the configuration data fetching when accepting new
5420 connections in the server. Affected file silcd/server.c.
5422 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added `sender_entry' argument to the function
5425 silc_server_packet_relay_to_channel so that we can check
5426 whether some destination actually belongs to the same route
5427 the sender belongs (ie, we must not resend the packet to the
5428 sender). Affected file silcd/packet_send.[ch].
5430 * Added `servername' field to the SilcClientEntry in the server
5431 to hold the name of the server where client is from. Affected
5432 file is silcd/idlist.h.
5434 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Moved the channel message encrypting in the router betwen
5437 router connections from silc_server_channel_message to the
5438 silc_server_packet_relay_to_channel since we want to check
5439 whether we have anybody channel before encrypting anything.
5440 Affected files silcd/packet_[receive/send].c.
5442 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Fixed the [AdminConnection] server config section to support
5445 multiple entries. Affected file silcd/serverconfig.c.
5447 * Added support into the server to check the validity of the
5448 incoming connection before executing any KE or authentication
5451 * The connection configuration is now saved to the KE and
5452 connection auth protocol contexts and not fetched anymore in
5453 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5455 * The local hosts listenning address and port is also resolved
5456 now when starting the server. We want to have the socket object
5457 to include the real address and port for the listener. Added
5458 new function silc_net_check_local_by_sock into the files
5459 lib/silcutil/silcnet.[ch].
5461 * Fixed a broadcast bug in server -> do not broadcast if we
5464 * Fixed a routing bug. Do not route broadcast packets ever.
5465 Broadcast packets must be processed always and not routed since
5466 they may be destined to some other host than yourself and thus
5467 would get routed without no good reason. Affected file is
5470 * Added function silc_server_config_is_primary_route to check
5471 whether primary router connection has been configured (a router
5472 configuration that we are initiating). If there is not, we
5473 will assume that there is only two routers in the SILC network
5474 and we will use the incoming router connection as our primary
5475 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5477 * Changed the order of the broadcasting. Broadcast _after_ the
5478 packet has been processed not before. Affected file is
5481 * Fixed a [ClientConnection] parsing bug. The port was never
5482 parsed correctly thus resulting to port 0. Affected file
5483 silcd/serverconfig.c.
5485 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5486 argument and did not set the broadcast packet flag. Affected
5487 file silcd/packet_send.c. Fixed same bug in the function
5488 silc_server_send_notify as well.
5490 * If we receive NEW_ID packet for our own ID in the server, ignore
5493 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Removed the nickname from the Private Message Payload.
5498 Updated the code and the protocol specs.
5500 * Updated protocol specs for submitting to the IETF.
5502 * Tweaked the Random Number Generator a bit. Affected file
5503 lib/silccrypt/silcrng.c. Exported a new function
5504 silc_rng_[global]_add_noise which can be used to add more
5507 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Do not parse packets with different timeout when protocol
5510 is active -> may cause problem with rekey. Affected file
5513 * When server receives signoff notify it must not create
5514 new channel key if the client is on any channels since the
5515 sender of the signoff notify will create it.
5517 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added printing of error messages during SKE protocol from the
5520 failure packet sent by server during SKE. Affected file
5523 * Removed the client's failure_callback handling with timeout
5524 and handle it immediately when received.
5526 * The SKE library returned wrong type in SUCCESS and FAILURE
5527 packets. They must be 32 bit MSB not 16 bit MSB.
5529 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Ok, rewrote the logic of the re-key and now it seems to work.
5532 I tested it on high traffic with frequent re-keys without
5533 problems. Added hmac_receive (and renamed hmac to hmac_send)
5534 in SilcClientConnection in lib/silcclient/client.h and
5535 in SilcIDListData in silcd/idlist.h. Also, removed the
5536 SilcPacketParserContext's cipher and hmac fields as they are
5537 not needed anymore and actually caused some problems when
5538 the ciphers and hmac's changed underneath the packet parser.
5540 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * If re-key protocol is active then process the incoming packets
5543 synchronously since we must assure that icoming packets encrypted
5544 with the old key is processed before the new keys is set to
5545 use. This is true other packets than for REKEY packets.
5546 Affected file silcd/server.c. The same was done to client library
5547 as well, affected file lib/silcclient/client.c.
5549 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Fixed bug in client and server to accept the force send if
5552 the packet is send from silc_[server/client]_packet_process
5553 function. Otherwise the packets are never delivered, oops.
5555 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Disable force sending of packets when REKEY protocol is active.
5558 We must assure that no packet is sent directly when rekey is
5559 performed. All packets must be sent through packet queue.
5560 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5561 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5562 function is silc_[server/client]_packet_send_real to check
5565 * Replaced the SIM paths from example config files to
5566 /usr/local/modules. Also, make install creates now
5567 /usr/local/silc/logs directory to hold all the SILC server
5570 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Made the configure.in.pre work on Solaris. Patch by salo.
5574 * Made all ciphers compatible with non-x86 machines. Defined
5575 CBC mode macros into lib/silccrypt/ciphers_def.h.
5577 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Fixed the make install.
5581 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * When MAC computation fails the silc_packet_decrypt returned 0
5584 even though it was supposed to return -1. Fixed this. The
5585 affected file is lib/silccore/silcpacket.c.
5587 * Do not replace the config files in /etc/silc (in make install)
5588 if they already exist. Affected file ./Makefile.am.
5590 * Do not send re-key packets immediately but through packet queue.
5591 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5593 * Changed silc_net_check_host_by_sock to return FALSE if the
5594 IP/DNS could not be resolved. Though, it returns the IP address
5595 now even if it could not resolve it (but returns also FALSE).
5596 Affected file lib/silcutil/silcnet.[ch].
5598 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added silc_pkcs_decode_identifier to decode the public key's
5601 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5602 Added also silc_pkcs_free_identifier. Added also new context
5603 SilcPublicKeyIdentifier.
5605 * Added -S option to the silc client. It is used to dump the
5606 contents of the specified public key file.
5608 * Changed the PKCS api to return the public key length when
5609 setting the public key.
5611 * Fixed a fatal bug in the public and private key file loading.
5612 Affected file lib/silccrypt/silcpkcs.c.
5614 * Execute the packet parsing for client with zero (0) timeout
5615 if the protocol is active. Affected file silcd/server.c.
5617 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * Made the key generation options to the silcd program. Added
5620 -C option, equivalent to client's option.
5622 * Added new [ServerKeys] config section to the server. It
5623 configures the server's public and private key.
5625 * Defined generic Public Key Payload into the protocol
5626 specification to send specific type of public keys and
5629 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5630 public key or certificate.
5632 * Implemented the GETKEY command to the server and to the
5633 client library and on user interface.
5635 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Made preliminary `make install' work.

5666 SilcClientConnection structure; not needed. Affected file is
5667 lib/silcclient/client.h.
5671 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Do not ask whether user wants to use the negotiated private key
5674 for private messages, just use it. Affected file is
5675 silc/local_command.c.
5677 * Added `send_enc_key' and `enc_key_len' fields to the
5678 SilcIDListData structure since they are needed in the re-key
5679 phase. Affected file is silcd/idlist.[ch].
5681 * Implemented the simple re-key protocol into the server.

5693 the PFS is to be performed in the re-key. Affected file is
5696 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5699 int64 of at least the xintXX size. If void * is less that 4
5700 bytes uint32 * will be used. Defined bool as boolean.
5702 * Changed _ALL_ unsigned long and unsigned int to uint32,
5703 unsgined short to uint16 in the source tree.
5705 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5706 not handle clients that has entry->data.registered == FALSE.
5707 They are not in the network anymore. Affected file is
5710 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Implemented the sending of the SERVER_SIGNOFF notify in the
5713 server. Affected file is silcd/server.c.
5715 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5716 Added also silc_notify_payload_encode_args into the

5720 Affected file silcd/packet_receive.c.
5722 * Implemented the SERVER_SIGNOFF notify handling in the client
5723 library. Affected file lib/silcclient/client_notify.c. Also,
5724 implemnted the printing of the SERVER_SIGNOFF info to the
5725 application. Affected file silc/client_ops.c.
5727 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5728 if the deleting was successful. Affected file silcd/idlist.[ch].
5730 * Added support for public key authentication in the connection
5731 authentication protocol in the client library. Affected file
5732 lib/silcclient/protocol.c.
5734 * Changed the server's silc_idlist_get_clients_by_* interface
5735 to support already allocated array so that new entries may be
5736 added to pre-allocated array. Affected file silcd/idlist.[ch].
5737 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5738 and command replies.
5740 * All command reply functions in the server now calls the
5741 pending command callback even if error occured. This way the
5742 error will be delivered to the client as well. Affected files
5743 silcd/command.c and silcd/command_reply.c.
5745 * Fixed INFO command to return local server's info if no server
5746 was provided. Affected file lib/silcclient/command.c.
5748 * Removed RESTART command for good. Updated the code and the

5752 Removed unsued task priorities. The affected files are
5753 lib/silcutil/silctask.[ch].
5755 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Moved the USERS printing from the library to the application.
5758 Affected files lib/silcclient/command.c and silc/client_ops.c.
5760 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Added channel key re-key support. The re-key is perfomed
5765 only by the router and is done once in an hour. Added `rekey'
5766 field to the SilcChannelEntry in the server. Affected files
5767 silcd/server.c and silcd/idlist.h.
5769 * Added silc_task_unregister_by_context into the file
5770 lib/silcutil/silctask.[ch].
5772 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added SILC_UMODE_GONE mode to indicate when the client is not
5775 present in the SILC network. Added also support to the local
5776 command AWAY that will set this mode. Added support of showing
5777 "xxx is gone" in WHOIS command. The USERS command shows the
5778 gone status as well.
5780 * Fixed setting server and router operator privileges in the
5781 server's UMODE command. Affected file silcd/command.c.
5783 * Merged the SKE KE1 and KE2 payloads into one payload. The
5784 new KE payload is equivalent to the old KE2 payload.
5786 Cleaned up the SKE Start Payload parsing. It now uses the
5787 simple buffer unformatting to do the parsing. A lot faster
5790 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5791 to the SKE that is used to indicate whether both of the SKE
5792 parties should perform authentication. By default only the
5793 responder performs authentication. By setting this flag also
5794 the initiator must do authentication. By default it is unset
5795 since in normal SKE case, client to server connection, only
5796 the responder should do authentication. When doing SKE between
5797 two clients both should perform authentication. Updated the
5798 code and the protocol specs.
5800 * A little fix to IDENTIFY command in the server. Search the
5801 client first by hash not nickname. Affected file is
5804 * Fixed the silc_client_close_connection to support closing
5805 the client to client connections wihtout deleting too much
5806 data. Affected file lib/silcclient/client.c.
5808 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5809 are received if protocol used to be active but is not anymore
5810 the application would crash due to NULL pointer dereference.
5811 Affected files silcd/server.c and lib/silcclient/client.c.
5813 * Added `hash' field to the SilcClientConnection to include
5814 the hash function negotiated in the SKE protocol.
5816 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5817 to set the channel founder authentication data. A client can
5818 claim the founder rights later by providing the authentication
5819 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5820 This way the channel founder can regain the channel founder
5821 privileges even it is left the channel. This works only on
5822 local server and the client must be connected to the same
5823 server to be able to regain the founder rights. Updated the
5824 protocol specs accordingly.
5826 Added support to the CMODE command in the client to set the
5827 founder auth data. Read the README to see how to set it.
5829 Added support to the CUMODE command to claim the founder
5830 rights. Read the README to see how to do it.
5832 Added support for the founder authentication to the Channel
5833 Entry in the server. Affected file silcd/idlist.h.
5835 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5836 server's CMODE command. Affected file silcd/command.c.
5838 * Added the following new functions into lib/silccore/silcauth.[ch]:
5839 silc_auth_get_method and silc_auth_get_data.
5841 * The server now saves the remote hosts public key to the
5842 SilcIDListData pointer. Affected file silcd/protocol.c.
5844 * The normal server now does not remove the channel entry from
5845 the cache if the founder authentication data is set. It used
5846 to remove it if the founder was the last one on the channel on
5847 the server and left the channel. The auth data is saved and
5848 if the channel is re-joined later the old entry is used with
5849 the old auth data. Affected files silcd/command_reply.c and
5852 * Removed the `pkcs' field from the SilcIDListData structure
5853 in the server; it is not used. Affected file silcd/idlist.h.
5855 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Fixed packet processing on slow links. Partial packets were
5858 never re-processed because the incoming data buffer was cleared
5859 by the application. Application must not directly clear the
5860 sock->inbuf, the packet processing routines handle it. Fixed
5861 this in client library and in server.
5863 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Fixed the WHOIS and IDENTIFY send reply function to really
5866 check whether to send list or just one entry. Affected file
5869 * Cleaned up the LEAVE command's channel key distribution. The
5870 affected file silcd/command.c.
5872 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5873 can enforce the channel mode as well. In that case the ID
5874 includes the ID of the server. The code now enforces the
5875 mode change if the router have different mode than the server.
5877 * The notify client operation with CMODE_CHANGE notify can now
5878 return NULL client_entry pointer if the CMODE was not changed
5879 by client. Application must check for this.
5881 * Added <Server ID> argument to INFO command to support server
5882 info fetching by Server ID.
5884 * Added silc_server_announce_get_channel_users to get assembled
5885 packets of channel users of the specified channel. Affected
5886 file silcd/server.[ch].
5888 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5889 was freed underneath the ID Cache.
5891 * Re-announce clients when the server received CHANNEL_CHANGE
5892 notify from the router. Affected file silcd/packet_send.c.
5894 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5897 crashed since it did not handle the fact that there is no cipher
5898 called "3" and didn't check the error condition. Now fixed.
5900 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5901 flag. It can be used to send message requests.
5903 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Implemented the RESTART command in the client.
5907 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5908 notice type messages. Added notice printing to the user
5911 * The channel keys are not re-generated if the channel's mode
5912 is PRIVKEY, ie private key on the channel exists. Affected
5913 files silcd/server.c and silcd/command.c.
5915 * Fixed a little bug in channel message delivery when channel
5916 private keys are set in the server. Affected file is
5917 silcd/packet_send.c.
5919 * Changed the setting on channel->on_channel = TRUE from the
5920 silc_client_save_channel_key to the JOIN command reply. The
5921 key payload is not received if the private channel key is set.
5922 Affected file lib/silcclient/command_reply.c and the
5923 lib/silcclient/client_channel.c.
5925 * When the CMODE_CHANGE notify is sent and the channel private
5926 key mode is removed the channel key must be re-generated in
5927 other cells as well. Added this support for the router in the
5928 silcd/packet_receive.c.
5930 * Added new local command NOTICE to send notice message on
5931 channel. Affected file silc/local_command.[ch].
5933 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added new local command ME to the client. It is used to send
5936 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5937 some action. Affected file silc/local_command.[ch].
5939 * Changed channel_message and private_message client operations
5940 to deliver the message flags to the application. Added also
5941 the `flags' arguments to the silc_client_send_channel_message
5942 and silc_client_send_private_message functions. Affected file
5945 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Redefined the Private Message Payload to support private message
5948 keys and to support the new private message flags. Updated
5949 the protocol specs. Flags makes it possible to have for example
5950 CTCP style messages.
5952 * Added new type SilcPrivateMessagePayload and defined an API
5953 for it in the lib/silcclient/silcprivate.[ch].
5955 * Tested private message private keys successfully. Tested the
5956 private message key set, unset and list commands with the new
5959 * Redefined the Channel Message Payload to include the channel
5960 message flags (equal with private message flags) to support
5961 for example CTCP style messages.
5963 * Defined some of the message (for channel and private message)
5964 flags. Updated the protocol specs and added the flags to the
5965 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5967 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Added SilcKeyAgreementStatus type to the key agreement routines
5970 to indicate the current status and error if one occured.
5971 The status types are defined in the lib/silcclient/silcapi.h.
5973 * Added new local command KEY that is used to set and unset private
5974 keys for channels, set and unset private keys for private messages
5975 with remote clients and to send key agreement requests and
5976 negotiate the key agreement protocol with remote client. The
5977 key agreement is supported only to negotiate private message keys,
5978 it currently cannot be used to negotiate private keys for channels,
5979 as it is not convenient for that purpose.
5981 * Fixed a minor pending callback setting bug in the function
5982 silc_client_get_client_by_id_resolve, now the function works.
5983 Affected file lib/silcclient/idlist.c.
5985 * Added function silc_net_get_local_port to get local bound
5986 port by socket. Added to lib/silcutil/silcnet.[ch].
5988 * Added `sockets' and `sockets_count' fields to the SilcClient
5989 object. They hold the sockets of the listenning sockets in
5990 the client. Listenning sockets may be for example the key
5991 agreement server. Affected file lib/silcclient/client.[ch].
5992 Added functions the silc_client_add_socket and the
5993 silc_client_del_socket. They are exported to the application
5996 * Added ~./silc/clientkeys to support other client's public keys.
5998 * Renamed verify_server_key client operation to verify_public_key
5999 and added one argument to indicate the type of the connection
6000 (server, client etc.).
6002 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added silc_server_connection_auth_request to handle the
6005 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6006 silcd/packet_receive.[ch].
6008 * Added silc_server_send_connection_auth_request into the
6009 silcd/packet_send.c to send the connection auth request packet.
6011 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6014 * Fixed the public key authentication in responder side in the
6015 server. The `auth_data' pointer includes the SilcPublicKey
6016 not the path to the public key. Affected file silcd/protocol.c.
6018 * Implemented the public key authentication in the initiator side
6019 in the server. Affected file silcd/protocol.c.
6021 * Removed the [RedirectClient] config section from the server
6022 configuration. Is not needed and I don't want to implement it.
6024 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Cleaned up the CMODE command in the server. It now works
6027 correctly and supports all the modes defined in the protocol.
6028 Affected file is silcd/command.c.
6030 * Added `hmac_name' field to the SilcChannelEntry in the server
6031 to hold the default HMAC of the channel. It can be set when
6032 creating the channel (with JOIN command). Affected files
6035 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6036 type to indicate the change of the current cipher and hmac
6037 on the channel. Client can safely ignore the <cipher> argument
6038 (if it chooses to do so) since the CHANNEL_KEY packet will
6039 force the channel key change anyway. The <hmac> argument is
6040 important since the client is responsible of setting the new
6041 HMAC and the hmac key into use.
6043 * Fixed the CMODE command in the client library as well.
6045 * Tested CMODE command in router environment successfully.
6047 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Show the version of the remote client (or server) when connecting
6050 to the server. It is logged to the log file. Affected file
6051 is silcd/protocol.c.
6053 * Fixed the KILLED notify handling in the client library. The
6054 client must be removed from all channels when receiving the
6057 Also, do not remove the client entry when giving the KILL
6058 command but when the KILLED notify is received.
6060 * Removed silc_idlist_find_client_by_nickname from the server.
6061 Not needed anymore. Affected files silcd/idlist.[ch].
6063 * Implemented the CHANNEL_CHANGE notify type handling to the
6064 server. Affected file silcd/server.c.
6068 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Added silc_server_send_notify_invite to send the INVITE
6071 notify between routers.
6073 * Implemented the INVITE command correctly to the server.

6082 * Added function silc_server_get_client_resolve to find the
6083 client entry by ID from all ID lists and then resolve it
6084 (using WHOIS) if it cannot be found. Affected file is
6087 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Implemented the BAN command to the client library.
6091 * The JOIN command in the server now checks the invite list
6094 * Changed the silc_command_reply_payload_encode_va and the
6095 silc_command_payload_encode_va to support that if argument is
6096 NULL it ignores and checks the next argument. Affected file
6097 lib/silccore/silccommand.c.
6099 * Added silc_server_send_notify_ban to send the BAN notify
6100 type between routers.
6102 * Chaned the silc_notify_payload_encode to support that if
6103 argument is NULL it ignores and checks the next argument.
6104 Affected file lib/silccore/silcnotify.c.
6106 * Tested ban lists in router environment successfully.
6108 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Implemented BAN command to the server, in silcd/command.[ch].
6112 * Removed the BAN and INVITE_LIST modes from the CMODE command
6115 * Added function silc_string_match to regex match two strings.
6116 Affected files lib/silcutil/silcutil.[ch].
6118 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Redefined parts of the SilcChannelEntry in the server to support
6121 the new ban and invite lists.
6123 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Redefined the INVITE command. The same command can be used to
6126 invite individuals to the channel but also to manage the invite
6127 list of the channel (to add to and remove from the invite list).
6128 Updated the protocol specs.
6130 * Added new command SILC_COMMAND_BAN that can be used to manage
6131 the ban list of the channel. Updated the protocol specs.
6133 * Removed the channel modes: the SILC_CMODE_BAN and the
6134 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6135 in the CMODE command. The equivalent features are now available
6136 using INVITE and BAN commands. Updated the protocol specs.
6138 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6139 in the network about change in the current ban list. The notify
6140 type is not used by the client.
6142 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6143 support the invite lists.
6145 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added new function silc_string_regexify that converts string
6148 including wildcard characters into regex string that can
6149 be used by the GNU regex library. Added into the file
6150 lib/silcutil/silcutil.[ch].
6152 Added silc_string_regex_combine to combine to regex strings
6153 into one so that they can be used as one regex string by
6154 the GNU regex library. Added into the file
6155 lib/silcutil/silcutil.[ch].
6157 Added silc_string_regex_match to match two strings. It returns
6158 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6160 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Imported GNU regex to the soruce tree into lib/contrib.
6163 Fixed some compiler warning from the regex.c.
6165 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6173 in the server, as the `nickname' argument may be binary data
6176 * Added silc_idlist_get_channels to return all channels from
6179 * Implemented LIST command to the server. Affected file is
6182 * Implemented the LIST command to the client library and on the
6185 * Added [<user count>] argument to the LIST command reply.
6186 With private channels the user count is not shown.
6188 * Updated TODO and README.
6190 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * The client entry's data.registered must be TRUE even with
6193 global client entry on global client list. The data.registered
6194 is used to check whether the client is anymore in the network,
6195 for example with WHOWAS command so it must be valid.
6197 * Fixed the WHOWAS command in the server. It now actually works
6198 in router environment. Added function into silcd/command_reply.c
6199 silc_server_command_reply_whowas_save.
6201 * Added silc_idlist_purge function to the silcd/idlist.c
6202 to periodically purge the ID Cache.

6212 they were buggy because of the WHOWAS information.
6214 * Fixed local command MSG to handle the async resolving of
6215 the remote client properly. It used to fail the first MSG.
6216 Affected file silc/local_command.c.
6218 * Added `data_len' field to SilcIDCache context.
6220 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Update TODO. Todo in commands in the server.
6224 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6227 used by routers as broadcast packet to inform other routers
6228 about the changed user mode.
6230 Implemented the notify handling in the server. Affected file is
6231 silcd/packet_receive.c. Added the function
6232 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6234 * Added new generic Channel Payload and deprecated the New Channel
6235 Payload. The New Channel Payload is now the generic Channel
6238 * Added new argument `mode' to the silc_server_send_new_channel
6239 as it is required in the Channel Payload now.
6241 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6242 and created a new and real SilChannelPayload to represent the
6243 new generic Channel Payload. Implemented the encode/decode
6244 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6246 * Added silc_server_get_client_channel_list to return the list
6247 of channels the client has joined for WHOIS command reply.
6248 Affected file silcd/server.[ch].
6250 * Implemented the channel list sending in the WHOIS command reply
6251 in server and in the client.
6253 Implemented the channel list displaying on the user interface
6254 as well. Affected file silc/client_ops.c.
6256 * Added silc_channel_payload_parse_list to parse list of Channel
6257 Payloads. It returns SilcDList list of SilcChannelPayloads.
6258 Client for example can use this function to parse the list of
6259 channels it receives in the WHOIS command reply. The caller
6260 must free the list by calling silc_channel_payload_list_free.
6261 Affected files lib/silccore/silcchannel.[ch].
6263 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Added one new argument <user mode> to the WHOIS command reply

6282 unknown command. Affected file silcd/command.c.
6284 * All server commands now handle the command identifier the right
6285 way when sending the command reply to the client. The client can
6286 use to identify the command replies with the identifier.
6288 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_server_get_client_route to resolve the route to
6291 the client indicated by the client ID. Affected file is
6294 * Added silc_server_relay_packet as general function to relay
6295 packet to arbitrary destination. This deprecates functions
6296 like _send_private_message_key, _relay_notify etc. Affected
6297 file is silcd/packet_send.[ch].
6299 Removed silc_server_send_key_agreement,
6300 silc_server_send_private_message_key and
6301 silc_server_packet_relay_notify functions from the file
6302 silcd/packet_send.[ch].
6306 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6307 server. Affected file silcd/packet_receive.[ch].
6309 * Implemented the KILL command to the client. Implemented the
6310 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6311 Affected files lib/silcclient/command[_reply].c and
6312 lib/silcclient/client_notify.c. Implemented the KILL notify
6313 printing in the user inteface.
6315 * Fixed a lot silc_parse_nick memory leaks from the client
6316 library in the file lib/silcclient/command.c.
6318 * Changed the silc_server_send_notify_on_channels's `sender'
6319 argument from SilcSocketConnection to SilcClientEntry to
6320 check the sender as entry and not as connection object and not
6321 to send to the client provided as argument. The affected file
6322 is silcd/packet_send.[ch].
6324 * The notify packets that are destined directly to the client used
6325 to not to be processed by the server. Now changed that and the
6326 server processes all notify packets. After relaying the packet
6327 to the client the notify packet is processed in the server.
6329 * The silc_server_free_client_data now checks whether there is
6330 pending outgoing traffic for the client and purges the data to
6331 the network before removing the client entry.
6333 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6336 an client is killed from the SILC Network. Updated the protocol
6339 Added new function silc_server_send_notify_killed to the
6340 silcd/packet_send.[ch].
6342 * Added function silc_server_packet_relay_notify to relay notify
6343 packets that are destined directly to a client. In this case
6344 the server does not process the notify packets but merely relays
6345 it to the client. Affected file silcd/packet_send.[ch].
6347 Added also silc_server_packet_process_relay_notify to check
6348 whereto relay the notify. Affected file is
6349 silcd/packet_receive.[ch].
6351 * Implemented the KILL command to the server.
6355 * Added the backup schema desgined last fall to the protocol
6356 specs for everyone to see. The specification is in the
6357 *-spec-xx.txt draft and the packet type definitions for the
6358 backup routers is in *-pp-xx.txt draft. Thusly, added also
6359 new packet type SILC_PACKET_CELL_ROUTERS.
6361 * A big security problem in the implementation discovered. The
6362 signoff of an client did not cause new channel key generation
6363 which it of course should've done. The channel keys must be
6364 always re-generated when client leaves (or signoffs) the channel.
6365 The silc_server_remove_from_channels funtion now handles
6366 the channel key re-generation.
6368 * Added `sender' argument to the silc_server_send_notify_on_channels
6369 to not to send the client provided as argument. Affected file
6370 silcd/packet_send.[ch].
6372 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Implemented OPER and SILCOPER commands into the server and
6377 * Added silc_auth_verify and silc_auth_verify_data to verify
6378 the authentication directly from the authentication payload.
6379 It supports verifying both passphrase and public key based
6380 authentication. Affected file lib/silccore/silcauth.[ch].
6382 * Added `hash' field to the SilcIDListData structure. It is the
6383 hash negotiated in the SKE protocol. Affected file is
6386 * Slight redesigning of the SilcAuthPayload handling routines.
6387 Do not send SilcPKCS but SilcPublicKey as argument.
6389 * Implemented the public key authentication support to the
6390 serverconfig. The public key is loaded from the provided path
6391 and saved as authentication data to void * pointer. Thus,
6392 changed the unsigned char *auth_data to void *auth_data;
6394 * Fixed SHUTDOWN command to send the reply before the server
6395 is shutdown. :) Affected file silcd/command.c.
6397 * Fixed fatal bug in CONNECT command. The hostname was invalid
6398 memory and server crashed. Affected file silcd/command.c.
6400 * Fixed fatal bug in CLOSE command. The server_entry became
6401 invalid but was referenced later in the command. Affected file
6404 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Fixed fatal bug in failure packet handling. Server ignored
6407 the failure and thus crashed when it came.
6411 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6414 that the command may be executed only once in (about) 2 seconds.
6415 The old SILC_CF_LAG flag is same but allows command bursts up
6416 to five before limiting.
6418 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6419 server code. Various commands now includes the CF_LAG_STRICT
6420 flag to disallow any kind of miss-use of the command.
6422 * Fixed the silc_buffer_unformat to not to allocate any data
6423 if the length of the data is zero. It used to allocate the
6424 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6426 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Changed the format of AdminConnection configuration section
6429 in the server. Added username of the admin to the format.
6430 Affected files silcd/serverconfig.[ch].
6432 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6433 to return admin configuration data by host, username and/or
6436 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Implemented WHOWAS command to the server. Added the functions:
6440 silc_server_command_whowas_parse,
6441 silc_server_command_whowas_send_reply,
6442 silc_server_command_whowas_from_client and
6443 silc_server_command_whowas_from_server
6445 * Added <Client ID> argument to the WHOWAS command reply. Updated
6446 the protocol specs accordingly.
6448 * Implemented WHOWAS command and command_reply to the client
6451 Implemented the WHOWAS printing on the user interface.
6453 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Added new argument to the WHOWAS command reply, the real name.
6456 It is an optional argument. Updated the protocol specs.
6458 * Added SilcIDCacheDestructor callback that is registered when
6459 the SilcIDCache is allocated. The callback is called when
6460 an cache entry in the ID Cache expires, or is purged from the
6461 cache. Added into lib/silccore/idcache.[ch].
6463 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6464 to destruct the client entries when the cache entry expires.
6465 Other ID Cache's in server and in the client library ignores
6468 * If the ID Cache entry's `expire' field is zero then the entry
6469 never expires. Added boolean `expire' argument to the
6470 silc_idcache_add function in the lib/silccore/idcache.[ch].
6471 If it is TRUE the default expiry value is used.
6473 * Added silc_server_free_client_data_timeout that is registered
6474 when client disconnects. By default for 5 minutes we preserve
6475 the client entry for history - for WHOWAS command.
6477 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Added support to the server to enforce that commands are not
6480 executed more than once in 2 seconds. If server receives
6481 commands from client more frequently, timeout is registered
6482 to process the commands. Affected file silcd/command.c.
6483 Added new function silc_server_command_process_timeout.
6485 * Changed NICK_NOTIFY handling in client library to check that
6486 if the client's nickname was changed, so there is no need to
6487 resolve anything from the server.
6489 * Removed error printing from the WHOIS and IDENTIFY commands.
6490 If error occurs then it is ignored silently in the client library.
6491 The application, however, may map the received error to
6492 human readable error string. The application currently maps
6493 the NO_SUCH_NICKNAME error to string.
6495 * Made the command status message public to the application. Moved
6496 them from lib/silcclient/command_reply.c to
6497 lib/silcclient/command_reply.h. The application can map the
6498 received command status to the string with the
6499 silc_client_command_status_message function.
6501 * Added check to the server to check that client's ID is same
6502 as the Source ID in the packet the client sent. They must
6505 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Added dist-bzip hook to the Makefile.am to make bzip2
6508 compressed distributions.
6510 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Server now enforces the maximum length for the nickname and
6513 the channel as protocol specification dictates. 128 bytes for
6514 nickname and 256 bytes for channel name.
6516 * Moved the WHOIS printing to the application. The client libary
6517 does not print out the WHOIS information anymore, the application
6518 must do it. Renamed silc_client_command_reply_whois_print to
6519 the silc_client_command_reply_whois_save.
6521 The client's idle time is also sent to the application now, and
6522 the idle is shown on screen.
6524 * Added silc_client_command_reply_identify_save to save the
6525 received IDENTIFY entries.
6527 * Do not check for channel private keys in message sending and
6528 reception if the channel does not have the PRIVKEY mode set.
6529 Affected file lib/silclient/client_channel.c.
6531 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6534 just surfaced after chaning the JOIN procedure.
6536 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6538 * Added silc_client_get_clients_by_list to get client entries
6539 from Client ID list, that is returned for example by JOIN
6540 and USERS command replies. The application should use this
6541 function for example when JOIN command reply is received to
6542 resolve the clients already on the channel (library does not
6543 do that anymore as USERS command reply is not used in the JOIN
6544 procedure anymore). Affected files lib/silcclient/silcapi.h and
6545 lib/silcclient/idlist.c.
6547 * JOIN command reply and USERS command reply returns now SilcBuffer
6548 pointers instead of unsigned char pointers when returning
6549 the client list and mode list.
6551 * Added <Client ID> argument to the JOIN command reply, mainly
6552 for the server to identify for which client the command was
6553 originally sent. Updated protocol specs accordingly.
6555 * Added SilcDlist private_key pointer to the SilcChannelEntry
6556 in the client to support the channel private keys. Affected
6557 file is lib/silcclient/idlist.h.
6559 * Added SilcChannelPrivateKey argument to the function
6560 silc_client_send_channel_message so that application can choose
6561 to use specific private ke if it wants to. If it is not provided,
6562 the normal channel key is used, unless private keys are set.
6563 In this case the first (key that was added first) is used
6564 as the encryption key.
6566 * Implemented the support for channel private key handling.
6567 Implemented the following functions:
6569 silc_client_add_channel_private_key,
6570 silc_client_del_channel_private_keys,
6571 silc_client_del_channel_private_key,
6572 silc_client_list_channel_private_keys and
6573 silc_client_free_channel_private_keys
6575 Affected file lib/silcclient/client_channel.c.
6577 * Added the support for the private keys in the channel message
6578 sending and encryption and in the message reception and
6579 decryption. Affected funtions are
6580 silc_client_send_channel_message and silc_client_channel_message.
6582 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Added SKE's key verify callback to the client library's
6585 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6587 * Removed the statement that server (or router) must send USERS
6588 command reply when joining to the channel so that the client
6589 knows who are on the channel. Instead, the client list and
6590 client's mode list is now sent in the JOIN command reply to the
6591 client who joined channel. This is better solution.
6593 * Added function silc_server_get_users_on_channel and function
6594 silc_server_save_users_on_channel to the silcd/server.[ch].
6596 * Removed function silc_server_command_send_users from the
6599 * Do not show topic on the client library anymore. The topic is
6600 sent in the command reply notify to the application and the
6601 application must show the topic now.
6603 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Added client searching by nickname hash into the IDENTIFY and
6606 WHOIS commands in the server as they were clearly missing from
6607 them. Affected file is silcd/command.c.
6609 * Fixed a bug in private message receiving in the client library.
6610 The remote ID was freed and it wasn't supposed, now it is
6613 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Minor fix to the channel payload; allocate the data area, as it
6616 needs to be of specific length.
6618 * If the key agreement port is zero then the operating
6619 system will define the bound port. Affected files are
6620 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6622 * Added new function silc_channel_payload_decrypt into the file
6623 lib/silccore/silcchannel.[ch].
6625 * Moved the channel message etc, check from silc_packet_decrypt
6626 to applications. The library calls now a generic
6627 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6628 when the packet is either normal or special. This was done to
6629 allow more wide range of checking that was not allowed when
6630 the code was in library. Now applications can do virtually any
6631 checks to the packet and return to the library the decision how
6632 the packet should be processed. Affected files are
6633 lib/silccore/silcpacket.[ch].
6635 Added silc_server_packet_decrypt_check to the server and
6636 silc_client_packet_decrypt_check to the client library.
6638 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6639 to send with specified source and destination information.
6641 * Channel message delivery between routers was broken after the
6642 channel key distribution was fixed earlier. The channel key
6643 was used be to distributed to other routers as well which is not
6644 allowed by the protocol. Now this is fixed and channel keys
6645 really are cell specific and the channel message delivery between
6646 routers comply with the protocol specification.
6648 * Fixed various commands in server to check also the global list
6649 for the channel entry and not just the local list. The affected
6650 file silcd/command.c.
6652 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added assert()s to buffer formatting and unformatting routines
6655 to assert (if --enable-debug) when error occurs. Affected
6656 file: lib/silcutil/silcbuffmt.c.
6658 * Changed to auto-reconnect to check whether the remote host is
6659 router and register the re-connect timeout if it is. It used
6660 to check that whether we are normal server, but router must do
6661 auto-reconnect with another router as well. Affected file
6664 * Removed the [<key len>] option from CMODE command as the cipher
6665 name decides the key length, nowadays. See the defined ciphers
6666 from the protocol specification.
6668 * Added [<hmac>] option to the CMODE command to define the HMAC
6669 for the channel. Added SILC_CMODE_HMAC channel mode.
6671 * Added [<hmac>] option for the JOIN command so that user can
6672 select which HMAC is used to compute the MACs of the channel
6675 * Added Hmac field to the Channel Message Payload. The integrity
6676 of plaintext channel messages are now protected by computing
6677 MAC of the message and attaching the MAC to the payload. The
6678 MAC is encrypted. Now, it is clear that this causes some
6679 overhead to the size of the packet but rationale for this is that
6680 now the receiver can verify whether the channel message decrypted
6681 correctly and also when private keys are set for the channel the
6682 receiver can decrypt the packet with several keys and check from
6683 the MAC which key decrypted the message correctly.
6685 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6686 lib/silccrypt/silccipher.[ch].
6688 * Added silc_hash_len to return the digest length into the
6689 lib/silcrypt/silchash.[ch].
6691 * Rewrote parts of Silc Channel Payload interface in the
6692 lib/silccore/silcchannel.[ch]. The encode function now also
6693 encrypts the packet and parse function decrypts it.
6695 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed a minor formatting bug in the SKE's key material processing.
6698 It actually might have processed the keys wrong way resulting
6701 * Redefined the mandatory HMAC algorithms and added new algorithms.
6702 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6703 and hmac-md5 truncated to 96 bits. The mandatory is now
6704 hmac-sha1-96. Rest are optional (including the one that used
6705 to be mandatory). Rationale for this is that the truncated HMAC
6706 length is sufficient from security point of view and can actually
6707 make the attack against the HMAC harder. Also, the truncated
6708 HMAC causes less overhead to the packets. See the RFC2104 for
6711 * Added new [hmac] configuration section. The SKE used to use
6712 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6713 is of course wrong. The official names that must be proposed in
6714 the SKE are the ones defined in the protocol specification
6715 (hmac-sha1-96 for example). The user can configure any hmac
6716 using any hash function configured in the [hash] section. At
6717 least, the mandatory must be configured.
6719 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6721 * Added HMAC list to the SKE proposal list. It has now both
6722 hash algorithm list and HMAC list. This makes the protocol
6723 incompatible with previous versions. The SKE now seems to work
6724 the way it is supposed to work, for the first time actually.
6726 * Defined plain Hash algorithms to the protocol specification.
6729 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Implemented support for key agreement packets into the server.
6732 Added functions silc_server_key_agreement and
6733 silc_server_send_key_agreement. Other than these functions,
6734 server has nothing to do with this packet.
6736 * Added support for private message key packets into the server.
6737 Added functions silc_server_private_message_key and
6738 silc_server_send_private_message_key.
6742 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6743 called in the protocol's final callback instead in the END
6744 protocol state. This makes a little more sense and in the same
6745 time in client we can use the same protocol routines for normal
6746 key exchange and to key agreement packet handling as well.
6748 * Added to both client's and server's KE protocol context the
6749 SilcSKEKeyMaterial pointer to save the key material. We will
6750 bring the key material to the protocol's final callback by doing
6751 this. The final callback must free the key material.
6753 * Added SKE's packet_send callback into client's KE protocol
6754 context so that the caller can choose what packet sending function
6755 is used. This way we can use different packet sending when
6756 doing normal SKE when doing key agreement packet handling (in
6757 the key agreement packet handling we do not want to encrypt
6760 * Implemented the responder side of the key agreement routines
6761 in the client. The client can now bind to specified port and
6762 accept incoming key negotiation. The key material is passed
6763 to the application after the protocol is over.
6765 * Implemented the processing of incoming Key Agreement packet
6766 in the client. Added function silc_client_key_agreement to
6769 * Implemented the intiator side of the key agreement routines
6770 in the client. The client can now initiate key agreement with
6771 another remote client. The key material is passed to the
6772 application after the protocol is over.
6774 * Created client_keyagr.c to include all the key agreement
6777 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6778 SILC_TASK_CALLBACK except that it is not static.
6780 * Created client_notify.c and moved the Notify packet handling
6781 from the client.[ch] into that file.
6783 * Created client_prvmsg.c and moved all private message and
6784 private message key routines from the client.[ch] into that file.
6786 * Create client_channel.c and moved all channel message and
6787 channel private key routines from the client.[ch] into that file.
6789 * Changed silc_client_get_client_by_id_resolve to resolve with
6790 WHOIS command instead of IDENTIFY command, in the file
6791 lib/silclient/idlist.c.
6793 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Implemented the SKE's responder side to the Client library.
6797 * When FAILURE is received to the protocol do not trust it
6798 blindly. Register a timeout to wait whether the remote closes
6799 the connection as it should do it, only after that process the
6800 actual failure. This was changed to both client and server.
6802 * Added client_internal.h to include some of the structures
6803 there instead of client.h in lib/silcclient/.
6805 * Added function silc_task_unregister_by_callback to unregister
6806 timeouts by the callback function.
6808 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Some "Incomplete WHOIS info" errors has been appearing on the
6811 log files. Took away the entry->userinfo check from WHOIS
6812 reply sending. The entry->userinfo is now " " if client did not
6813 provide one. I thought this was fixed earlier but something
6814 is wrong still. Let's see if the error still appears.
6816 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Fixed a minor bug in the login when the channel key is
6819 re-generated in the server. It used to generate the key in
6820 wrong order and thus caused problems in the channel traffic.
6822 * Fixed a minor bug in channel key distsribution after
6823 KICK command. The key was not sent to the router even though
6826 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added silc_ske_process_key_material_data as generic routine
6829 to process any key material as the SILC protocol dictates. The
6830 function is used by the actual SKE library but can be used by
6831 applications as well. This relates to the private message keys
6832 and the channel private keys since they must be processed the
6833 same way the normal SILC session keys. The protocol dictates
6834 this. Affected files: lib/silcske/silcske.[ch].
6836 Added also silc_ske_free_key_material to free the
6837 SilcSKEKeyMaterial structure.
6839 * Defined silc_cipher_set_key function to set the key for
6840 cipher without using the object's method function. The affected
6841 files: lib/silccrypt/silccipher.[ch].
6843 * Implemented silc silc_client_add_private_message_key,
6844 silc_client_add_private_message_key_ske,
6845 silc_client_del_private_message_key,
6846 silc_client_list_private_message_keys and
6847 silc_client_free_private_message_keys functions in the
6850 Added functions silc_client_send_private_message_key to send
6851 the Private Message Key payload and silc_client_private_message_key
6852 to handle incoming Private Message Key payload.
6854 * Added Cipher field to the Private Message Key payload to set
6855 the cipher to be used. If ignored, the default cipher defined
6856 in the SILC protocol (aes-256-cbc) is used.
6858 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Removed lib/silcclient/ops.h file.
6862 Redefined parts of the SILC Client Library API. Created new
6863 file silcapi.h that deprecates the ops.h file and defines the
6864 published Client Library API. Defined also private message key
6865 API and channel private key API into the file.
6867 This is the file that the application must include from the
6868 SILC Client Library. Other files need not be included by
6869 the application anymore.
6871 * Added new key_agreement client operation callback and also
6872 defined the Key Agreement library API for the application.
6874 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6877 is used by clients to request key negotiation between another
6878 client in the SILC network. If the negotiation is started it
6879 is performed using the SKE protocol. The result of the
6880 negotiation, the secret key material, can be used for example
6881 as private message key.
6883 Implemented the Key Agreement payload into the files
6884 lib/silccore/silauth.[ch].
6886 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Redefined ciphers for the SILC protocol. Added some new ciphers
6889 and defined the key lengths for the algorithms. Changed the
6890 code accordingly. The default key length is now 256 bits.
6892 * Fixed SKE key distribution function silc_ske_process_key_material
6893 when the key length is more than 128 bits. The default key
6894 length in SILC is now 256 bits.
6896 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6897 to indicate unsupported algorithm.
6899 * Renamed rijndael.c to aes.c and all functions as well.
6901 * Fixed a long standing channel key setting bug in client library.
6902 Weird that it has never surfaced before.
6904 * Fixed bug in channel deletion. If the entire channel is removed
6905 then it must also delete the references of the channel entry
6906 from the client's channel list as the client's channel entry and
6907 the channel's client entry share same memory.
6909 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Implemented CONNECT and SHUTDOWN commands in the client.
6913 * Implemented CLOSE command to the client.
6915 * Added the function silc_idlist_find_server_by_name into the
6916 files silcd/idlist.[ch].
6918 Added the function silc_idlist_find_server_by_conn into the
6919 files silcd/idlist.[ch].
6921 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6923 * DIE command was renamed to SHUTDOWN. Updated the both code
6926 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6927 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6929 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6932 * Added function silc_server_create_connection function to create
6933 connection to remote router. My server implementation actually
6934 does not allow router to connect to normal server (it expects
6935 that normal server always initiates the connection to the router)
6936 so the CONNECT command is only good for connecting to another
6939 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6942 or some other client was kicked from the channel.
6944 Implemented the handling of the notify type to both client
6947 Implemented silc_server_send_notify_kicked to send the KICKED
6948 notify. It is used to send it to the server's primary router.
6950 * Implemented the KICK command into server and client.
6952 * Added `query' argument to the silc_idlist_get_client function
6953 to indicate whether to query the client from server or not if
6956 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6957 to indicate that the client is not channel founder.
6961 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Removed the rng context from SilcPacketContext structure and
6964 changed that the packet routine uses the Global RNG API.
6966 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Added support for quit message that client can "leave" on the
6969 channel when it quits the SILC. It is ditributed inside the
6970 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6972 Added silc_server_free_client_data that will take the
6973 signoff message as argument.
6975 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6977 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Updated parts of the protocol specification to keep it up
6982 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6985 payloads in one packet.
6987 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6988 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6989 use now the new List flag.
6991 * Also deprecated the following packet types: REPLACE_ID,
6992 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6994 * Added list support for Notify packet in server.
6996 * Added silc_server_send_notify_channel_change to send the
6997 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6998 the silc_server_send_replace_id.
7000 * Added silc_server_send_notify_nick_change to send the
7001 NICK_CHANGE notify type. Deprecates the function
7002 silc_server_send_replace_id.
7004 * Added silc_server_send_notify_join to send the JOIN notify type.
7005 Deprecates the function silc_server_send_new_channel_user.
7007 * Added silc_server_send_notify_leave to send LEAVE notify type.
7008 Deprecates the function silc_server_send_remove_channel_user.
7010 * Added silc_server_send_notify_cmode and
7011 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7012 types. Deprecates the silc_server_send_set_mode function.
7014 * Added SERVER_SIGNOFF notify type to indicate that server has
7015 quit. This means that all clients on the channel from that
7016 server will drop. This can be also used when netsplit happens.
7018 Deprecated REMOVE_ID packet type since it is not needed anymore
7021 Added silc_server_send_notify_server_signoff to send the
7022 SERVER_SIGNOFF notify type. Deprecates the function
7023 silc_server_send_remove_id.
7025 Added also silc_server_send_notify_signoff to send the
7026 SIGNOFF notify type.
7028 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7029 SILC protocol from this day on. Changed the protocol
7030 specification as well.
7032 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7033 notify type. It is used between routers to notify about
7034 topic changes on a channel.
7036 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7039 * Partly updated the protocol specification to comply with the
7040 changes now made. It is still though a bit outdated.
7042 * The JOIN notify type now takes one extra argument <Channel ID>.
7043 The packet used to be destined to the channel but now the
7044 JOIN type may be sent as list thus it is impossible to
7045 destine it to any specific channel. By adding this argument
7046 it is again possible.
7048 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Added CREDITS file. The CHANGES and CREDITS file will appear
7051 in the distribution as well.
7053 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7056 types in the server's silcd/packet_receive.c.
7058 * Implemented CMODE and CUMODE to work in router environment.
7060 * Fixed minor encoding and decoding buglet from the
7061 lib/silccore/silcmode.c.
7063 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7066 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7068 * Changed all SilcConfigServer* and silc_config_server* to
7069 SilcServerConfig* and silc_server_config*, respectively.
7072 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Associated the ID (client or server ID) to the Authentication
7075 Payload to avoid any possibility of forging. Updated the
7076 protocol specification and the code accordingly.
7078 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * The RSA key length is now save to the RsaKey context in the
7081 key generation process in lib/silccrypt/rsa.c. The key length
7082 is now used to figure out the maximum size of the block allowed
7083 to be encrypted/signed.
7085 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7086 is equivalent to the silc_mp_mp2bin but does not allocate any
7089 * Changed silc_mp_mp2bin API to take length argument. If it is
7090 non-zero then the buffer is allocated that large. If zero, then
7091 the size is approximated using silc_mp_sizeinbase, which however
7094 * Created Global RNG API which is global RNG that application can
7095 initialize. After initializing, any routine anywhere in the
7096 code (including library) can use RNG without allocating a new
7097 RNG object. This was done to allow this sort of use of the
7098 RNG in code that has no chance to allocate RNG object. All
7099 applications currently allocate this and many routines in the
7100 library use this. Affected file lib/silccrypt/silcrng.[ch].
7102 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7103 it to use the Global RNG API.
7105 * Defined Authentication Payload into protocol specification that
7106 is used during SILC session to authenticate entities. It is
7107 used for example by client to authenticate itself to the server
7108 to obtain server operator privileges.
7110 Implemented this payload into the lib/silccore/silcauth.[ch].
7111 Implemented also routines for public key based authentication
7112 as the new protocol specification dictates.
7114 Moved definitions of different authentication methods from
7115 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7117 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7118 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7119 silc_pkcs_verify_with_hash functions into the file
7120 lib/silccrypt/silcpkcs.[ch].
7122 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * The client entry's userinfo pointer must be always valid.
7125 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7126 will fail since it requires the userinfo. Now, the userinfo
7127 is allocated as "" if actual userinfo does not exist. Actually,
7128 it must exist and it is totally Ok to drop client connections
7129 that does not announce the userinfo. However, we will make
7130 this workaround for now.
7132 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7133 to return the remote port by socket.
7135 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7138 SILC_SERVER_PENDING_EXEC and added an new macro
7139 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7140 data or when error occurs while processing the pending command.
7142 Added new argument `destructor' into silc_server_command_pending
7143 and to the SilcServerCommandPending object. This destructor is
7144 now called after calling the pending callback or if error occurs
7145 immediately. If error occurs the actual pending callback won't
7146 be called at all - only the destructor. The destructor may be
7147 NULL if destructor is not needed.
7149 All this applies for client library code as well. Similar
7150 changes were made there as well for the pending commands.
7152 In the client, the application must now allocate the
7153 SilcClientCommandContext with the silc_client_command_alloc
7156 * Added reference counter to the SilcServerCommandContext. Added
7157 function silc_server_command_alloc and silc_server_command_dup
7160 Same type of functions added to the client library for the same
7163 * Removed the cmd_ident from IDListData away since it is now
7164 global for all connections. It is the command identifier used
7165 in command sending and with pending commands. The affected file
7168 * Added reference counter to the SilcSocketConnection objecet to
7169 indicate the usage count of the object. The object won't be
7170 freed untill the reference counter hits zero. Currently only
7171 server uses this, and client ignores it. The client must be
7172 set to use this too later. The affected files are
7173 lib/silccore/silcsockconn.[ch]. Added also the function
7174 silc_socket_dup to increase the reference counter.
7176 This was mainly added because it is possible that the socket
7177 is removed underneath of pending command or other async
7178 operation. Now it won't be free'd and proper DISCONNECTING
7179 flags, etc. can be set to avoid sending data to connection that
7180 is not valid anymore.
7182 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7183 the connection. After that it sets SILC_SET_DISCONNECTED.
7184 It is, however, possible that the socket data is not still freed.
7185 The silc_server_packet_process now checks that data is not
7186 read or written to connection that is DISCONNECTED. The socket
7187 get's freed when the reference counter hits zero.
7189 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7191 * Changed the client operation API: channel_message operation's
7192 `sender' is now the client entry of the sender, not the nickname
7193 and the `channel' is the channel entry, not the channel name.
7195 In the private_message operation the `sender' is now also the
7196 client entry of the sender not the nickname.
7198 Affected file is lib/silcclient/ops.h and all applications
7199 using the client operations.
7201 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Moved the calling of ops->connect() from connect_to_server_final
7204 into receive_new_id functin since that is the point when the
7205 client is actually allowed to send traffic to network. The
7206 affected file is lib/silcclient/client.c.
7208 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7211 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7212 (if needs broadcasting) instead of broadcasting the packets one
7213 by one which would make a burst in the network traffic.
7215 * Added `broadcast' argument to the functions in silcd/server.[ch]
7216 silc_server_create_new_channel[_with_id] to indicate whether
7217 to send New Channel packet to primary router.
7219 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Added new function into the silcd/server.[ch] files:
7222 silc_server_create_new_channel_with_id to create new channel with
7223 already existing Channel ID.
7225 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7226 lib/silccore/silcpacket.h. This packet is used t send list of
7227 Set Mode payloads inside one packet. Server uses this to set
7228 the modes for the channels and clients on those channels, that it
7229 announced to the router when it connected to it. The protocol
7230 specification has been updated accordingly.
7232 * The silc_server_new_channel did not handle the packet coming
7233 from normal server as it normally does not send that. However,
7234 when it announces its channels it does send it. Implemented
7235 the support for that.
7237 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7238 into the file lib/silccore/id.h.
7240 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Fixed memory leaks in the functions silc_idlist_del_client,
7243 silc_idlist_del_channel and silc_idlist_del_server in the file
7244 silcd/idlist.c. All of those leaked like a sieve.
7246 * Fixed some small memory leaks in the client's function
7247 silc_client_notify_by_server.
7249 * Added functions into silcd/server.c: silc_server_announce_clients,
7250 silc_server_announce_channels and silc_server_announce_server.
7251 These functions are used by normal and router server to announce
7252 to its primary router about clients, channels and servers (when
7253 router) that we own. This is done after we've connected to the
7256 These functions effectively implements the following packet types:
7257 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7258 and SILC_PACKET_NEW_ID_LIST.
7260 * Added new functions into the silcd/packet_receive.[ch]:
7261 silc_server_new_id_list, silc_server_new_channel_list and
7262 silc_server_new_channel_user_list to handle the incoming
7263 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7265 * Added support of changing Channel ID in the function
7266 silc_server_replace_id. If the server that announces a channel
7267 to the router already exists in the router (with same name but
7268 with different Channel ID), router is responsible to send
7269 Replace ID packet to the server and force the server to change
7270 the Channel ID to the one router has.
7272 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7273 client that the Channel ID has been changed by the router. The
7274 normal server sends this to the client. Client must start using
7275 the new Channel ID as the channel's ID.
7277 Implemented handling of this new type into lib/silcclient/client.c
7278 into the function silc_client_notify_by_server.
7280 * Added new function silc_idlist_replace_channel_id into the files
7281 silcd/idlist.[ch] to replace the Channel ID.
7283 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Call silc_server_command_identify_check always when processing
7286 the IDENTIFY command in silcd/command.c
7288 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7291 send keepalive packets. The packet can be sent by clients,
7292 servers and routers.
7294 Added function silc_socket_set_heartbeat into the file
7295 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7296 If not set, the heartbeat is not performed. The actual
7297 heartbeat is implemented in the low level socket connection
7298 library. However, application is responsible of actually
7301 Added silc_server_send_heartbeat to send the actual heartbeat
7302 packet into silcd/packet_send.[ch]. Server now performs
7303 keepalive with all connections.
7305 * Added silc_task_get_first function into lib/silcutil/silctask.c
7306 to return the timeout task with shortest timeout. There was a bug
7307 in task unregistration that caused problems. TODO has been
7308 updated to include that task system must be rewritten.
7310 * The client library will now resolve the client information when
7311 receiving JOIN notify from server for client that we know but
7312 have incomplete information.
7314 * Rewrote parts of silc_server_remove_from_channels and
7315 silc_server_remove_from_one_channel as they did not remove the
7316 channel in some circumstances even though they should've.
7318 * Encryption problem encountered in server:
7320 The LEAVE command used to send the Channel Key packet to the
7321 router immediately after generating it. However, the code
7322 had earlier sent Remove Channel user packet but not immediately,
7323 ie. it was put to queue. The order of packets in the router
7324 was that Channel Key packet was first and Remove Channel User
7325 packet was second, even though they were encrypted in the
7326 reverse order. For this reason, MAC check failed. Now, this
7327 is fixed by not sending the Channel Key packet immediately but
7328 putting it to queue. However, this is more fundamental problem:
7329 packets that are in queue should actually not be encrypted
7330 because packets that are sent immediately gets encrypted
7331 actually with wrong IV (and thus MAC check fails). So, packets
7332 that are in queue should be encrypted when they are sent to
7333 the wire and not when they put to the queue.
7335 However, the problem is that the current system has not been
7336 designed to work that way. Instead, the packet is encrypted
7337 as soon as possible and left to the queue. The queue is then
7338 just purged into wire. There won't be any fixes for this
7339 any time soon. So, the current semantic for packet sending
7342 o If you send packet to remote host and do not force the send
7343 (the packet will be in queue) then all subsequent packets to the
7344 same remote host must also be put to the queue. Only after the
7345 queue has been purged is it safe again to force the packet
7348 o If you send all packets immediately then it safe to send
7349 any of subsequent packets through the queue, however, after
7350 the first packet is put to queue then any subsequent packets
7351 must also be put to the queue.
7353 Follow these rules and everything works fine.
7355 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Added new function silc_server_remove_clients_by_server to
7358 remove all client entries from ID list when the server connection
7359 is lost. In this case it is also important to invalidate all
7360 client entires as they hold the invalid server entry. This
7361 fixes fatal bug when server has lost connection and will reconnect
7364 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Made some sanity checks to silc_server_daemonise like to check
7367 whether the requested user and group actually exists.
7369 * Added sanity check to SKE's silc_ske_responder_finish to check
7370 that the public and private key actually is valid.
7372 * Invalidate the client's nickname when receiving Replace ID
7373 packet and the Client ID is being replaced. This means that the
7374 server will query the nickname if someone needs it (client)
7377 * Sort the ID Cache in client library when the ID Cache data
7378 has changed (needs sorting).
7380 * Do not allow for SILC client to create several connections to
7381 several servers. The client does not support windows right now
7382 and generating multiple connections causes weird behaviour.
7384 Irssi-silc client does support windows and can handle several
7385 connections without problems, see: www.irssi.org and SILC plugin.
7387 * Fixed some places where client was added to the IDList. The
7388 rule of thumb is following (in order to get everything right):
7389 If the client is directly connected local client then the
7390 `connection' argument must be set and `router' argument must be
7391 NULL to silc_idlist_add_client function. If the client is not
7392 directly connected client then the `router' argument must
7393 bet set and the `connection' argument must be NULL to the
7394 silc_idlist_add_client function.
7396 * The funtion silc_server_packet_send_local_channel actually did
7397 not check whether the client was locally connected or not. It
7398 does that now. Fixed a bug related to LEAVE command.
7400 * Fixed Remove Channel User payload parsing bug in server's
7401 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7403 * The server's silc_server_save_channel_key now checks also the
7404 global ID list for the channel as it might not be in the local
7405 list. Fixed a bug related to LEAVE command.
7407 * Is this the end of the [<unknown>] buglet that has been lurking
7408 around for a long time? A little for loop fix in server's
7409 silc_server_command_whois_parse that is used by both IDENTIFY
7410 and WHOIS command. At least, this was a clear bug and a cause
7411 of one type of [<unknown>] buglet.
7413 * WHOIS and IDENTIFY commands call the function
7414 silc_server_command_[whois/identify]_check function even if
7415 we are not router server.
7417 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Added --with-gmp configuration option. If set the GMP
7420 is always compiled in the SILC source tree. If not set then
7421 it is checked whether the system has the GMP3 installed. If
7422 it has then the GMP won't be compiled (the system's headers
7423 and library is used), if it doesn't have it then the GMP is
7424 compiled in the SILC source tree.
7426 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Changed RSA private exponent generation to what PKCS #1
7429 suggests. We try to find the smallest possible d by doing
7430 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7431 not security fix but optimization.
7433 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7435 * Added new config entry [Identity] to fork the server and run
7436 it as specific user and group. A patch from Bostik.
7438 * Imported Dotconf configuration library into lib/dotconf.
7439 This will be used to create the SILC configuration files later.
7440 It will appear in the distsribution after this commit.
7442 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * A big code auditing weekend happening. Auditing code for
7445 obvious mistakes, bugs and errors. Also, removing any code
7448 Removed files for being obsolete:
7450 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7451 inline in the file lib/silcutil/silcbuffer.h)
7453 o lib/silcutil/silcbufutil.c (the header has inline versions)
7455 Changed code to fix possible error conditions:
7457 o The buffer formatting routines now check that the destination
7458 buffer really has enough space to add the data. This applies for
7459 both buffer formatting and unformatting
7460 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7461 unformatting was changed to accomodate following rules:
7462 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7463 sent to the function while XXX_*STRING will not allocate or copy
7464 the data into the buffer. Instead it sets the pointer from the
7465 buffer into the pointer sent as argument (XXX_*STRING used to
7466 require that the pointer must be allocated already). This change
7467 makes this whole thing a bit more consistent and more optimized
7468 (note that the data returned in the unformatting with XXX_*STRING
7469 must not be freed now). The routines return now -1 on error.
7471 o Tried to find all code that use buffer_format and buffer_unformat
7472 and added return value checking to prevent formatting and
7473 especially unformatting errors and possible subsequent fatal
7476 o Changed ske->x and ske->KEY to mallocated pointers in
7477 lib/silcske/silcske.h. Fixed possible data and memory leak.
7479 o Added return value checking to all *_parse* functions. Fixed
7480 many memory leaks as well.
7482 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7483 so that buffer overflows would not happen. All code now also
7484 checks the return value as it can fail.
7486 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Added reconnection support to server if the normal server looses
7489 its connection to the router (for example if router is rebooted).
7490 The server performs normal reconnection strategy implemented
7491 to the server. Affected file silcd/server.c.
7493 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added new packet type SILC_PACKET_SET_MODE that is used to
7496 distribute the information about changed modes (for clients,
7497 channels and clients channel modes) to all routers in the
7498 network. Updated the protocol specification accordingly.
7500 Added functions into silcd/packet_send.c and
7501 silcd/packet_receive.c: silc_server_send_set_mode,
7502 silc_server_set_mode.
7504 Added new files silcmode.[ch] into lib/silccore that implements
7505 the encoding and decoding of Set Mode Payload. Added new type
7506 SilcSetModePayload. Moved the definitions of different modes
7507 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7509 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Oops, a little mistake in server's connection authentication
7512 protocol. The protocol is not ended with FAILURE but with
7513 SUCCESS if the authentication is Ok. :) Affected file is
7516 * Implemented NICK_CHANGE notify handling in server in the file
7517 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7518 the local clients on the channel. After the changing nickname
7519 in router environment snhould work and the [<unknown>] nickname
7520 should appear no more.
7522 The silc_server_replace_id function that receives the Replace ID
7523 payload now sends the NICK_CHANGE notify type also in the file
7524 silcd/packet_receive.c
7526 * Changed WHOIS and IDENTIFY command to support the maximum amount
7527 of arguments defined in protocol specs (3328 arguments). This
7528 fixed a bug that caused problems when there were more than three
7531 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7533 * Added extra parameter, command identifier, to the
7534 silc_client_send_command so that explicit command identifier
7537 Changed that ID list routines uses specific command identifier
7538 when sending WHOIS/IDENTIFY requests to the server so that they
7539 can be identified when the reply comes back.
7541 Affected files lib/silcclient/command.[ch],
7542 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7544 * Added `sender' argument to silc_server_packet_send_to_channel
7545 to indicaet the sender who originally sent the packet to us
7546 that we are now re-sending. Ignored if NULL. Affected file
7547 silcd/packet_send.[ch].
7549 * Added some server statistics support in silcd/server_internal.h
7550 SilcServerStatistics structure and around the server code. Also
7551 send some nice statistics information when client is connecting
7554 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Fixed channel ID decoding in server's JOIN command reply in
7557 silcd/command_reply.c
7559 * Fixed braodcasting of replace ID payload to not to send it if
7560 we are standalone server in silcd/packet_receive.c.
7562 * Fixed all channel message sending routines to not to send
7563 packets to clients that has router set, since they are routed
7564 separately in the same function earlier. Affects file
7565 silcd/packet_send.c and all channel packet sending functions.
7567 * In USERS reply, res_argv[i] are not allocated, the table
7568 is allocated. Thus changed that free the table, not its
7571 * In server's whois_check and identify_check if the client is
7572 locally connected do not send any WHOIS commands - they are not
7575 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Fixed some minor bugs in client when sending WHOIS command. The
7578 arguments was in wrong order.
7580 * Removed statis function add_to_channel from server in
7581 silcd/command.c that was previously used with the joining but
7584 * Tested USERS command in router environment successfully with two
7585 routers, two servers and two clients.
7587 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * Reorganized the USERS command and command reply in client library
7590 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7591 When the command is given by user we register a pending command
7592 callback that will reprocess the command after the reply has been
7593 received from the server. When reprocessing the packet we then
7594 display the information. Thus, the USERS information is displayed
7595 now in the command callback instead of in the command reply
7596 callback. The processing of the command is same as previously
7597 when server has sent the command reply in the JOINing process.
7599 * Added to USERS command in silcd/command_reply.c to join the client,
7600 we didn't use to know about, to the channel after we've created
7601 a client entry for it. Also, for clienet we did know already still
7602 check whether it is on the channel or not and add it if not.
7604 * Removed silc_server_command_join_notify as the function and its
7607 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Changed the client's pending command handling to the same as the
7610 server's pending command handling. It is also now possible to
7611 execute command reply functions from other command reply
7612 function as the function callbacks for commands and command
7613 replies are one and same. The pending commands are not static
7614 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7615 in client connection context. Thus, pending commands are server
7616 connection specific as it is convenient.
7618 Changed the function silc_client_command_pending and
7619 silc_client_command_pending_del and added new function
7620 silc_client_command_pending_check. Removed the
7621 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7624 * Added cmd_ident, current command identifier, to the client
7625 connection context in lib/silcclient/client.h to keep track on
7626 command identifiers used in command sending. Client's command reply
7627 function handling now supports the mandatory command identifiers.
7629 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7630 funtions in client to fully support pending command callbacks.
7632 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7633 as one of the arguments to the application in the command reply
7636 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7637 before first releasing SILC but came back. Now it is removed again
7638 and should come back nomore. The FORWARDED flag was used only
7639 by the JOINing procedure by forwarding the command packet to router.
7640 Now, the JOINing procedure has been changed to more generic (due
7641 to various router environment issues) and FORWARDED is not needed
7642 anymore for anything. The protocol specification is yet to be
7645 Now, removed silc_server_packet_forward from server and the flag
7646 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7648 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Renamed NAMES command to USERS command. The NAMES was named that
7651 due to historical reasons. Now it is renamed. Also, rewrote
7652 parts of the USERS command. The nickname list is not sent anymore
7653 by the server. Only Client ID and mode lists are sent in the USERS
7654 command. Changed this also to the protocol specification.
7656 The client now resolves the names and stuff after it receives
7657 the USERS list from the server when joining to the channel.
7659 * WHOIS and IDENTIFY commands has been changed to support multiple
7660 Client ID's per command. One can now search for multiple users
7661 in the network by sending only one WHOIS or IDENTIFY command.
7662 Changed the code and the protocol specifications.
7664 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7665 uses silc_server_command_whois_parse to parse the request. */
7667 * If normal server, do not parse the WHOIS and IDENTIFY requests
7668 before sending it to the router. Saves some time.
7670 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7672 * Fixed JOIN command on client library. Wrong number of arguments
7673 used to crash the client.
7675 * Added silc_server_channel_has_global function to check whether
7676 channel has global users or not.
7678 * Added silc_server_channel_has_local function to check whether channel
7679 has locally connected clients on the channel.
7681 * The silc_server_remove_from_one_channel now checks whether the
7682 channel has global users or not after given client was removed from
7683 the channel. It also checks whether the channel has local clients
7684 on the channel anymore. If it does not have then the channel entry
7685 is removed as it is not needed anymore.
7687 * The silc_server_notify now checks on JOIN notify whether the joining
7688 client is one of locally connected or global. If it is global then
7689 the channel has now global users on the channel and that is marked
7690 to the channel entry. Also, it now saves the global client to
7691 global list who is joining and JOINs it to the channel. This is
7692 for normal server, that is.
7694 Changed silc_server_send_notify_on_channel,
7695 silc_server_packet_relay_to_channel and
7696 silc_server_packet_send_to_channel check if we are normal server
7697 and client has router set (ie. global client) do not send the
7698 message to that client, as it is already routed to our router.
7700 * Implemented LEAVE notify type handling in silc_server_notify
7703 * Tested LEAVE command in router environment successfully. Tested
7704 with two routers, two servers and two clients.
7708 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7710 * Implemented SIGNOFF notify type handling in silc_server_notify
7713 * silc_server_remove_id now removes the client entry from all channels
7714 it has joined and thusly sends SIGNOFF notify type.
7716 * Rewrote the NAMES list generation in server by removing two excess
7717 loops. The lists are created now inside one loop.
7719 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * silc_server_remove_channel_user checks now also global list
7722 for channel and client.
7724 * silc_server_new_channel_user checks now both local and global
7725 list for channel and client. Fixed a bug in client id decoding.
7726 Used to decode wrong buffer.
7728 * silc_server_channel_message checks now both local and global
7729 list for channel entry.
7731 * Tested channel joining (hence JOIN) in router environment
7732 successfully. Tested with two routers, two servers and two
7735 * Tested channel message sending in router environment successfully.
7737 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Added silc_server_save_channel_key into server.[ch] to save the
7740 received channel key in Channel Key payload processing. It is
7741 also used in JOIN command reply handling.
7743 Equivalent function silc_client_save_channel_key added into
7744 client.[ch] into client library.
7746 * Changed JOIN command reply to send information whether the channel
7747 was created or not (is existing already) and the channel key
7748 payload. Changed protocol specs accordingly.
7750 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7751 the request was sent by ID and not by nickname. Crashed on
7754 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7757 now correctly save the received data.
7759 * silc_server_free_sock_user_data now notifies routers in the
7760 network about entities leaving the network.
7762 At the same time implemented functions silc_server_remove_id
7763 and silc_server_send_remove_id to receive and send REMOVE_ID
7764 packets. The packet is used to notify routers in the network
7765 about leaving entities. The ID removed will become invalid in
7768 * Added function silc_idlist_del_server into server. Removes and
7769 free's server entry from ID list.
7771 * silc_server_private_message function now checks, if we are router,
7772 that the destination ID really is valid ID, naturally.
7774 * In router when NEW_ID packet is received (for new client) the
7775 hash of the Client ID is saved in the ID Cache but the
7776 client->nickname is set to NULL, instead of putting the hash
7779 IDENTIFY command now also checks that client->nickname must be
7780 valid. If it is not if will request the data from the server who
7781 owns the client. Added new function
7782 silc_server_command_identify_check.
7784 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7785 to set the command to already allocated Command Payload.
7787 * Tested private message sending in router environment with two
7788 routers, two servers and two clients. Fixed minor bugs and now
7791 * Fixed segfault from client's NAMES command. Used to crash if
7794 * Forwarded packets must not be routed even if it is not destined
7795 to the receiver. Changed server code comply with this.
7797 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Added `require_reverse_mapping' boolean value to ServerParams
7800 structure. If TRUE (not default) the server will require that
7801 the connecting host has fully qualified domain name.
7803 If the reverse mapping is not required and hostname could not be
7804 found the IP address is used as hostname.
7806 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7808 * Implemented version string checking to both client and server.
7809 The check is incomplete currently due to the abnormal version
7810 strings used in development version of SILC.
7812 * Changed all command functions in server to use the new
7815 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Changed char *data to unsigned char *data in ID Cache system to
7818 support binary data as ID Cache data. Changed code to support
7819 binary data in lib/silccore/idcache.c.
7821 * Renamed silc_server_packet_relay_command_reply to
7822 silc_server_command_reply as it is normal packet receiving
7823 function. Rewrote the function to accept command replys for
7824 servers and not only for clients.
7826 * Mark remote router always as registered server if we are connecting
7827 to it. Otherwise, commands sent by the router to us are ignored.
7829 * All ID List find routines now returns the ID Cache Entry pointer
7830 as well if requested.
7832 * WHOIS command works now in router environment, tested with two
7833 routers, two servers and two clients.
7835 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7836 in router environment (as it is almost equivalent to WHOIS) but
7837 hasn't been tested thoroughly. Added new functions:
7839 silc_server_command_identify_parse
7840 silc_server_command_identify_send_reply
7841 silc_server_command_identify_from_client
7842 silc_server_command_identify_from_server
7844 * Disabled route cache adding because adding two different ID's with
7845 same IP replaces the old cache entry thus giving wrong route.
7846 The entry->router->connection is always the fastest route anyway
7847 so route cache may not be needed. Of course, new routes maybe
7848 established after receiving the ID when the entry->router->connection
7849 might not be anymore the most optimal.
7851 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7853 * Add route cache for received ID for fast routing.
7855 * Added silc_server_packet_route to route received packet on router
7856 that is not destined to us.
7858 * Renamed silc_server_get_route to silc_server_route_get.
7860 * Added id_string and id_string_len fields into SilcServer to
7861 include encoded ServerID for fast comparing without excess
7862 encoding of the ID's.
7864 * Cleaned up WHOIS command on server side. Added following static
7867 silc_server_command_whois_parse
7868 silc_server_command_whois_check
7869 silc_server_command_whois_send_reply
7870 silc_server_command_whois_from_client
7871 silc_server_command_whois_from_server
7873 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7874 arguments in command replies. All command functions should be
7875 updated to use this macro.
7877 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * Minor typo fixes on command reply handling on server.
7881 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Added silc_server_command_add_to_channel internal routine to add
7884 the client to the channel after router has created the channel and
7885 sent command reply to the server.
7887 * Added generic silc_server_send_command to send any command from
7890 * Use static buffer with ID rendering instead of duplicating data.
7892 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7894 * Fixed a channel user mode bug when joining to a channel server gave
7895 everybody channel founder rights, oops.
7897 * We mark ourselves as the router of the incoming server connection
7898 if we are router ourselves. This way we can check in some packet
7899 sending functions whether it is locally connected server. For
7900 incoming router connections we put NULL.
7902 * For router sending packets locally means now always sending the
7903 packet cell wide; to local clients and local servers. For normal
7904 server sending packet locally means sending it to only local
7907 * Fixed the JOIN command to really work in router environment. If the
7908 channel is created it is always created by the router. Router is
7909 also responsible of making the initial joining to the channel,
7910 sending JOIN notify to the sending server and distributing
7911 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7912 does not exist server doesn't do anything else but forward the
7913 command to the router which performs everything.
7915 * Added silc_server_send_channel_key function to send the Channel Key
7918 * Added silc_server_create_channel_key to create new channel key. The
7919 channel key is now re-generated everytime someone joins or leaves
7920 a channel, as protocol dictates. Note: channel->key_len is the
7923 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7925 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7926 packet_receive.[ch] to separate packet sending and receiving
7927 routines. The server.[ch] now includes everything else including
7928 actual packet processing (writing and reading data) and other
7931 Renamed silc_server_private_message_send_internal to
7932 silc_server_send_private_message. The routine is still though
7933 used only to relay private messages as server does not send
7934 private messages itself.
7936 Renamed silc_server_new_channel to silc_server_create_new_channel
7937 and added new function sicl_server_new_channel that handles the
7938 incoming New Channel packet. Added also new sending function
7939 silc_server_send_new_channel to send New Channel Payload.
7941 * Added new function silc_server_notify to process incoming notify
7942 packet to the server/router. Server may then relay the notify
7943 to clients if needed.
7945 * Added new function silc_server_new_channel_user to process incoming
7946 New Channel User packet. Router will redistribute the packet and
7947 send JOIN notify to its local clients and locally connected servers
7948 if needed. Normal server will send JOIN notify to its local client
7949 on same channel when received this packet. Added also corresponding
7950 sending function silc_server_send_new_channel_user to sent the
7953 * Added boolean route argument to send_notif_to_channel and
7954 packet_send_to_channel functions to attempt to route the packet
7955 if it is TRUE and send only locally if it is FALSE.
7957 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7959 * silc_server_replace_id now broadcasts the received replace ID
7960 packet if it is not broadcast packet already. The router must
7961 broadcast to inform other routers about changed ID.
7963 * Added backpointer to server's router into SilcServer context in
7964 silcd/server_internal.h.
7966 * Fixed silc_server_packet_broadcast to send correct broadcast
7969 * The channel key is now distributed to the local client as soon
7970 as it is received from the router (in router environment) so that
7971 no other packet may be sent for the channel until client has
7974 * silc_server_remove_channel_user now broadcasts the received
7975 Remove Channel User packet if it is not broadcast packet already.
7976 The router must broadcast to inform other routers about removed
7979 * Added users field into SilcPacketContext that is a reference count
7980 of the context. One can increase the reference count by calling
7981 silc_packet_context_dup which is now changed to just increase the
7982 reference count instead of duplicating the data. The reference
7983 count is decresed by calling silc_packet_context_free that will
7984 free the data after the reference count hits zero.
7986 For now on the packet context and everything allocated into it
7987 (including the raw packet from network) must be freed by calling
7988 the new silc_packet_context_free function. Added also new function
7989 silc_packet_context_alloc that must be used now to allocate the
7990 context. This also means that if a routine is asynchronous from
7991 silc_[client/server]_packet_parse_type the packet context must
7992 be duplicated by calling silc_packet_context_dup. Otherwise it
7993 gets free'd after silc_[client/server]_packet_parse_type returns.
7994 Also, one must remember that if packet is duplicated then its
7995 reference count must be decresed by calling the free function as
7996 many times as it was duplicated.
7998 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7999 from both client and server.
8001 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8003 * Made joining to a channel working in router environment.
8005 * Cleaned up JOIN command on server side and create function
8006 silc_server_command_join_channel internal routine to make the
8009 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Changed silc_command_pending list to SilcDList. Also, added
8012 `ident' field to SilcServerCommandPending structure to identify
8013 the reply and to call correct callback.
8015 Added silc_server_command_pending_check function to replace the
8016 corresnponding macro. The silc_command_pending list is not
8019 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8020 to set identifier to previously allocated Command Payload. It
8021 is used to set identifier for command when resending Command
8024 * Added silc_command_payload_encode_payload to encode Command
8025 Payload buffer from SilcCommandPayload structure.
8027 * Added silc_argument_payload_encode_payload to encode Argument
8028 payload buffer from SilcArgumentPayload structure.
8030 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8032 * Changed WHOIS command to support router connection on server side.
8033 The whois request is always sent to router unless the server is
8034 standalone server. After server has received the reply from the
8035 router will it send the reply to the client.
8037 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8038 broadcast received broadcast packet. The function is used only
8039 by router. The broadcast packet is always sent to the router's
8042 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8043 render given ID to printable string, for log files for example.
8045 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Made basic router to router connections working. At least they
8048 can now connect to each other but nothing really works the way
8049 they are supposed - yet.
8051 * Added new initiator token to RouterConnection configuration
8052 file in silcd/serverconfig.[ch]. It is used to tell whether we
8053 are the initiator to the remote router or whether we'll expect
8054 the other end to connect.
8056 * Moved registering of listener task to silc_server_init, hence
8057 the server starts listenning as soon as it is run, even if it
8058 does not have connections to other routers. Let's see how well
8061 * Changed default connection retry timeouts for more suitable in
8064 * Removed cipher and such arguments from silc_idlist_add_client
8065 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8066 Added new function silc_idlist_add_data to add the keys and stuff
8069 * Added SilcIDListData structure and added it to SilcClientEntry
8070 and SilcServerEntry as their first field in the structure. This
8071 way we can explicitly cast the ID entries to the SilcIDListData
8072 structure and get common data for the entries. In past, we had
8073 to first check what type of connection it is and then cast it to
8074 correct ID entry type. Now, we can directly cast the opaque
8075 pointer to the SilcIDListData (no matter what ID entry it actually
8076 is) and get the data needed.
8078 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8081 in some circumstances even if threre were timeout tasks, though not
8082 IO tasks, but tasks anyway. Now fixed.
8084 * Defined SilcServerConnection structure to hold connection specific
8085 stuff about directly connected servers and routers. The definition
8086 is currently in silcd/server_internal.h. I thought about having
8087 a bit more important role fro this struct but for now it is used
8088 only when connecting to other server (or router actually).
8090 * Added connecting retry support in server when connecting to
8091 router(s). The retry feature implement exponential backoff
8092 algorithm. Also, added SilcServerParams structure to hold default
8093 parameters for server. For now, it include these retry settings
8094 and are hard coded. After server is moded to be as Silc Server
8095 Library this structure will be more important.
8097 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8099 * Changed client librarys channel->clients table to SilcList and
8100 changed code accordingly.
8102 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Changed client's channel table to SilcList and changed code
8105 accordingly. Also changed SilcChannelClientEntry to include back-
8106 pointer to the channel so that client entry can use that structure
8107 as list as well and we have fast cross-reference to the channel.
8108 This change dramatically decreased the complexity of channel
8109 handling with client entry and vice versa (removed one extra
8110 loop when searching for channel entry from many functions).
8112 * Changed server->sim from table to SilcDList and changed code
8115 * NAMES command can now be used from user interface. It will show
8116 the user list on the channel, neatly.
8118 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8119 Code now saves realname of the user if it becomes available.
8121 * Renamed configure.in to configure.in.pre and made ./prepare
8122 script to automatically add correct version string to
8123 configure.in which it creates from configure.in.pre.
8125 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8127 * NAMES command reply now shows users mode with the nickname when
8130 * Moved silc_client_ch[u]mode[_char] functions from
8131 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8132 place sucks, they are utility functions and should be in some
8135 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8137 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8140 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Added TRQ (efficient deque and list library) into lib/trq. This is
8145 a very good list library that is currently used in the SILC. Defined
8146 SilcList API over the library because I didn't like the API very
8147 much. See lib/trq/silclist.h for the API and examples of how to
8148 use the API. Fixed various places in the code to use the new
8149 SilcList API. The SilcList is meant for lists that has a structure
8150 already defined as a list. It is not suitable to add just some
8151 context to the list (in TRQ, the context is the list actually).
8153 So, I defined SilcDList that can be used for the purpose where
8154 predefined list structure does not exit. This can be used as
8155 such list. Now some context just can be added to the SilcDList.
8156 Currently this list is not used in the SILC just yet, though there
8157 are a lot places where this can replace dynamically allocated
8158 tables and I will fix these places, later, to use SilcDList.
8159 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8160 and use TRQ internally).
8162 Also fixed some annoying warning messages that the original TRQ
8163 code generated. Also minor changes to TRQ's Makefile.in.
8165 * Added support for querying by Client ID to both WHOIS and
8166 IDENTIFY commands into server, as required by the protocol.
8168 * Removed method function pointers from SilcBuffer structure. They
8169 weren't used to anything and just increased the context size for
8170 no good reason. This change also made silc_buffer_alloc and
8171 silc_buffer_free functions inline functions.
8173 * Disabled command flooding detection support until it's fixed so
8174 that it accepts commands in but does not execute them more than once
8177 * Added silc_net_localhost(), to return local hostname, into
8178 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8179 that must be initialized before calling silc_client_init.
8181 * Added new function: silc_server_send_notify_on_channels to send
8182 notify messages to all channels client has joined. It is assured
8183 that the message is sent only once per client.
8185 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8186 lib/silcutil/silcutil.[ch] as silc_format function. The new
8187 function is generic and is used by server as well, not only by
8188 the logging routines.
8190 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8191 the provided version string was not acceptable. Added new function:
8192 silc_ske_check_version into lib/silcske/silcske.h. The function
8193 must be implemented by the application (client or server) and it
8194 does not reside in the SKE library. The function checks the version
8195 string remote end sent.
8197 * Added back pointers (to opaque context and to SilcSocketConnection)
8198 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8200 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8201 duplicate packet context structure.
8203 * Changed `notify' client operation to send same arguments as client
8204 receives from server except for ID's. ID's are mapped to correct
8205 ID entry and that is returned. Also, if channel entry is not sent
8206 by server but the notify is for channel the channel entry is sent
8207 to application (otherwise application doesn't know that it is for
8208 channel (library gets it from packet's Destination ID)).
8210 * Added silc_client_remove_from_channels into client library to
8211 remove a client from all channels it has joined to. Used when
8212 received SIGNOFF notify from server. Added also new function
8213 silc_client_replace_from_channels to replace old ID entry with
8214 new ID entry on all channels. Used when received NICK_CHANGE
8217 * Fixed ID Cache list handling in silc_idlist_get_client in
8218 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8219 to get (or query) client by ID.
8221 * Updated TODO list.
8223 * Added connection authentication status message defined by the
8224 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8225 support for these into the code in client and server side.
8227 * Added generic function silc_client_send_command to send any command
8228 with variable argument list. Application should use this function
8229 to send commands if the command functions provided by the library
8230 does not suite for the application's user interface needs.
8232 * Added new `failure' client operation. Application is notified about
8233 received failure packet if client is executing a protocol. In this
8234 case the protocol's execution has failed.
8236 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8237 is required by the protocol.
8239 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8240 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8243 * Added status flag to SilcSKE object to indicate realtime status
8244 of the SKE protocol.
8246 * Application receives now exactly same command reply arguments as
8247 the library receives from server. However, if ID is received the
8248 corresponding ID entry is returned to the application (eg. Client
8249 ID is mapped to correct SilcClientEntry entry and that is returned).
8250 Changed command_reply client operation due to this change.
8252 * Changed all ID's in commands and in command replys as ID Payloads.
8253 Change affected both client and server side codes.
8255 All ID's sent in SILC network (with execption of ID's in SILC
8256 Packet header) are sent in ID Payload to support variable length
8259 * Server now notifies nick changes and notifies all clients on
8260 the channels about the new nickname (about the new Client ID,
8263 * Implemented CMODE command to change channel modes. Supports all
8264 channel modes defined by the protocol specs except ban and invite
8265 lists. (Also, private channel key mode is supported but support for
8266 setting private channel key in client is missing, thus, this mode
8267 has no effect on client side (except that server requires that the
8268 client uses private channel key and normal channel traffic does not
8271 Also, invite mode works per se, but INVITE command does not work
8272 yet correctly, so you can set channel as invite only channel but
8273 inviting clients to the channel does not work (it is yet to be
8274 thought what's the best way to do it).
8276 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8277 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8278 Implemented CUMODE command to change user's mode on the channel.
8279 Supports all modes defined by the protocol specs.
8281 * Added NAMES command reply to return users modes on the channel.
8283 * Removed unnecessary and slow ciphers from lib/silccrypt.
8285 * Set SO_KEEPALIVE option to connection sockets by default.
8287 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8289 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8290 redefined the Notify Payload into protocol specs.
8292 * Added silc_id_payload_parse_id to get ID directly from raw
8295 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8297 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8298 accept searching by Client ID as well.
8300 * Added support for LEAVE and SIGNOFF notify types in client library.
8302 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8303 to parse ID Payload from raw data.
8305 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8307 * Added flags parameter into silc_ske_assemble_security_properties
8308 function in lib/silcske/silcske.[ch].
8310 * Changed notify client operation to fit better for notify messages
8311 sent by server. The notify payload received from server is now
8312 passed to the application (after parsing it to SilcNotifyPayload).
8313 It is application's responsibility to retrieve the arguments
8314 from the payload and show the message the way it wants. The message
8315 sent by server is implementation specific.
8317 * Changed public keys to comply with the protocol specification.
8318 Old public keys are not supported anymore and are not compatible.
8320 * Removed nickname from Channel Payload as the latest draft removed
8321 it. The client must resolve the nickname from the NAMES command
8322 reply received when it joined the channel.
8324 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8326 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8328 * Fixed some errors in protocol specification drafts.
8330 * Created lib/silccore/silcnotify.c to implement Notify Payload
8331 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8332 generic payloads described by protocol specifications. The file
8333 includes implementations for ID Payload and Argument Payload.
8335 * Changed Command Payload implementation to use the new Argument
8336 Payload. Changed command_xxxx_payload to command_payload_xxxx
8337 to comply with SILC coding conventions.
8339 * Added suppport for Argument Payload handling in Notify Payload
8340 implementation as protocol requires it. Added the new support
8341 into server and client lib as well.
8343 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8345 * Added support for multiple nicknames on same channel. [n] is
8346 added locally to the nickname if there are more than one same
8347 nicknames on the channel.
8349 * Server now sends all nicknames that matched WHOIS request.
8350 Client also shows the list received from server.
8352 * Added TOPIC command to client side. User can now set and show
8353 current topic on channel.
8355 * Added MOTD command to client and server. Also, server sends the
8356 motd when client connects to the server.
8358 * Changed version strings to comply ISO 8601.
8360 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8362 * Fixed protocol error handling in client library. It should now
8363 cope even if the SKE fails for some reason.
8365 * Made new protocol specification drafts for submitting to IETF.
8367 * Implemented TOPIC command to server in silcd/command.c.
8369 * Added two new notify types into lib/silccore/silcnotify.h:
8370 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8371 notify nickname change and topic setting/change on a channel.
8373 * API change of command_reply operation in client library. The
8374 application gets now the status type received from server as well.
8376 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8380 * Cras fixed and optimized the packet handling even further and
8381 it should work now. Minor change to the prototype of function
8382 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8384 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added new function into lib/silcutil/silcschedule.[ch]:
8387 silc_schedule_with_fd to select() a specified fd. The function
8388 returns after timeout expires or data arrives or goes. The
8389 function is used by packet routines to wait that all data is
8390 received from network.
8392 * Fixed data reading from network in lib/silccore/silcpacket.c.
8393 The code now assures that all data is read from the fd and then
8394 continues packet processing. This was a bug fix since the code
8395 used to drop some data in some circumstances.
8397 * Added new function into lib/silcclient/client.[ch]:
8398 silc_client_start_key_exchange to start key exchange after
8399 connection has been established to server. The code internally
8400 now uses this funtion but its main purpose was to provide it
8401 for applications that perform their own connecting. After
8402 application has created a connection it merely calls this
8403 function to start the key exchange between client and server.
8404 The library takes care of everything else after that.
8406 Updated also lib/silcclient/README to explain the usage of
8409 * Do not send to application information that connection has
8410 been established. Application gets notified it by connect
8413 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8415 * Applied cras's patch to add silc_schedule_one function. The
8416 function runs scheduler once and returns.
8418 * Fixed the scheduler after cras messed it up. The timeout
8419 handling works now as it's supposed to work.
8421 * Added into lib/silccore/ silcnotify.h to include notify
8422 message types support. Changed silc_server_send_notify*
8423 functions, in server.[ch], to support those new notify types.
8424 Added the support for the notify types into client library,
8425 as well. Added new notify client operation into ops.h in
8428 * Changed silc_server_packet_send_to_channel to send normal
8429 packets instead of just channel message packets. The function
8430 is now used to send the notify packets to channels. It is not
8431 used to send channel message packets anymore, as server never
8434 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8435 va_arg()s as it seems to require it nowadays. I guess, if SILC
8436 is compiled with older va_arg() the new code should work anyway.
8438 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8440 * Splitted core library. Core library (lib/silccore) includes
8441 now only SILC protocol specific core (and common) components.
8442 Created new utility library (lib/silcutil) that includes more
8443 generic purpose stuff. The stuff for util library was taken
8444 from the old core library. This was minor and easy split.
8446 * Created SILC Client Library (lib/silcclient) that includes
8447 implementation of the SILC client without user interface. This
8448 was major move from silc/ directory. The code has been changed
8449 so that it is transparent towards the user interface. The
8450 silc/ directory includes now the same user interface as before
8451 and it uses the new client library. Read lib/silcclient/README.
8452 Basicly, the client library performs everything else related
8453 to SILC except user interface handling. Also, configuration
8454 files are considered to be part of user interface and library
8455 does not handle them.
8457 This change also changed a lot of structures, function naming etc.
8458 Most important change was that SilcClientWindow object was
8459 renamed to SilcClientConnection in the client library. Created
8460 also new file lib/silcclient/ops.h. Also added new files
8461 silc/local_command.[ch] and silc/client_ops.[ch].
8463 All these changes were made to make it easier for user interface
8464 designers to create what ever user interface for the SILC client
8467 It is also expected that the server will be moved to lib
8468 directory as well and SILC Server Library will be created;
8469 sometimes in the future.
8471 * Removed Local commands from lib/silccore/silccommand.h as
8472 they are application specific and new client library does not
8473 handle any of those anymore.
8475 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8476 old client implementation in silc/.
8478 * Added support for callback functions in SILC_LOG_* macros.
8479 Application can now set its own callbacks that will be called
8480 instead of using the default functions that will always print
8481 the debug messages to stderr (or stdout). Also, debugging can
8482 now be disabled by setting silc_debug to FALSE and re-enabled by
8483 setting it to TRUE. Note, that logging will still work even
8484 if debugging is disabled.
8486 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8487 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8488 silc_log_reset_debug_callbacks.
8490 * To enable debugging in silc client one must give now -d
8491 option on command line.
8493 * Changed silc_schedule_init to automatically allocate task queues
8494 if they are not allocated before calling it.
8496 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8498 * Added GMP 3.1 into math library.
8500 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8502 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8503 a channel in SILC network. The packet is used by servers and
8504 routers to notify other routers that user has left a channel.
8505 This little feature was missing until now. Added the feature
8506 to protocol specification as well.
8508 Added functions: silc_server_send_remove_channel_user and
8509 silc_server_remove_channel_user into server.[ch].
8511 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8512 lib/silccore/silcpacket.h. However, they are not implemented
8515 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8517 * Fixed joining to a channel and sending channel messages
8518 between server and router. The channel message sending should
8519 now work inside a cell.
8521 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8523 * Fixed the private message sending between server and router.
8524 The private message sending should now work inside a cell.
8526 * Added silc_server_replace_id into server.[ch] to replace
8527 existing ID in the SILC network.
8529 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8530 and silc_idlist_replace_server_id into idlist.[ch] in server.
8532 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8534 * Fixed the server to server connections. Server can again now
8535 connect to router. Router to router connections probably does
8538 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8540 * Added dynamic protocol registering support. Now protocols can
8541 registered and unregistered on the fly. Patch by cras.
8543 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8545 * Added lib/contrib directory to hold routines that some platforms
8546 don't have but are needed by SILC.
8548 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8549 into lin/contrib to provide getopt() and getopt_long() for
8550 those who don't have it.
8552 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8554 * Added AWAY command to client. When away message is set and
8555 client receives a private message packet the client automatically
8556 replies to the sender with the away message.
8558 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8559 bug seemed to be the cause of recent problems when compiling
8562 * Added version detection support to SKE protocol specification
8563 and added the new changes to the SKE implementation as well.
8564 There were other minor changes in the SKE protocol as well.
8566 Many changes in lib/silcske/silcske.[ch] and in
8567 lib/silcske/payload.[ch].
8569 * Added ^U functionality, clear input line. Patch from cras.
8571 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8573 * Mainly small bugfixes on core library. Fixed some debugging
8574 logging and buffer overflow in silclog.c.
8576 * Updated config.sub and config.guess on the distribution tree.
8578 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8580 * Added command lagging support in server. Client may execute
8581 commands now only once in two seconds.
8583 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8585 * Optimized packet reception. MAC computation and checking is now
8586 also more optimized. A lot previously duplicated code is now
8587 used as generic by both client and server.
8589 * Fixed key pair generation in clientutil.c
8591 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8593 * Added into lib/silccore/silcbufutil.[ch] new function;
8594 silc_buffer_realloc.
8596 * Moved generic packet sending/encryption functions to
8597 lib/silccore/silcpacket.[ch] from client and server. Some
8598 rewriting of the functions.
8600 * Moved all generic packet reception/decryption functions to
8601 lib/silccore/silcpacket.[ch] from client and server. The
8602 packet processing is now much cleaner in both client and server.
8603 These were major changes in both client and server.
8605 * Created many common functions in server to do packet sending.
8606 Previously code were duplicated a lot, this has been removed
8609 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8611 * Rewrote major parts of the ID cache system. Don't know
8612 whether it is better now or not but at least the API is more
8615 * Major rewrite on ID cache stuff on client because of the ID
8616 cache API changes. Added idlist.c to client.
8618 * Also major rewrite on ID cache stuff on server as well.
8619 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8620 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8621 in hand, instead they are all put into the ID cache system now.
8622 All server_idlist_* routines uses ID cache now instead of
8623 traversing its own lists (those lists does not exist anymore).
8624 SilcIDList though still exists. Also, SilcXXXEntry's are
8627 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8629 * Finally made the SKE implementation compliant to the protocol
8630 specification. All mp integers are now binary encoded as
8631 opposed being HEX encoded.
8633 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8636 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8637 functions: silc_[encode/decode]_pem. Also added function
8638 silc_encode_pem_file to PEM encode with newlines ('\n') for
8641 * SILC public keys are now encoded either PEM or binary. Same
8642 option is for private keys as well. By default private keys
8643 are binary encoded and public keys PEM encoded. Silly HEX
8644 encoding were removed.
8646 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8647 function to create fingerprints.
8649 * Fixed a bug in SHA1; does not change the original data anymore.
8651 * Partly implemented INFO command on client and server side.
8652 Fixed CLEAR command. Changes to SERVER command; show current
8653 server(s) when giving command without arguments. Added
8654 VERSION command to client.
8656 * Added check to server that unregistered connections cannot
8657 execute commands (unless it is specificly allowed).
8659 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8661 * Fixed screen refresh.
8663 * Fixed channel joining bug from client. On some circumstances
8664 client tried to join to a channel it had already joined.
8666 * Added public key verification process into client's protocol.c.
8667 The client now verifies the public key from user and saves
8668 it into ~./silc/serverkeys/ directory.
8670 Added into: clientutil.[ch]: silc_client_verify_server_key.
8672 * Changed SKE protocol's silc_ske_initiator_finish function
8673 to accept callback function that verifies the received public
8674 key. Removed old silc_ske_verify_public_key function.
8676 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8678 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8679 silc_pkcs_private_key[_data]_set.
8681 * Made the password and public authentication more cleaner in
8682 server's protocol.c.
8684 * Removed historic and obsolete protocol `channel_auth' from
8685 both client and server.
8687 * Removed wrong way of sending command status messages from
8688 server to client in server's command.c. The old way violated
8689 protocol specification.
8691 Changes to silccore/silccommand.[ch]: removed
8692 silc_command_encode_status_payload -> not needed anymore,
8693 changed silc_command_encode_payload_va to accept extra
8694 argument on variable argument list. The argument type must
8695 now be provided to the function. Also, added new function:
8696 silc_command_encode_reply_payload_va which is same as
8697 normal command_encode_payload_va except command status type
8698 is provided as extra argument.
8700 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8702 * Added ~./silc directory handling. The directory includes the
8703 public and private keys for the client.
8705 Added silc_client_check_silc_dir, silc_client_create_identifier
8706 and silc_client_load_keys.
8708 * Implemented SILC protocol compliant public key. Added public
8709 and private key saving to and loading from files.
8711 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8712 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8713 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8714 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8715 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8717 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8718 silc_pkcs_load_[public/private]_key.
8720 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8722 * Added silc_server_get_route (route.[ch]) to get connection
8723 data for the fastest route for given ID.
8725 * Implemented INVITE command on client and server. The command
8726 were re-defined in the SILC Protocol Specification and the
8727 implementation now complies with the specification.
8729 * Implemented PING command on client and server.
8731 * Implemented NAMES command on client and server. The server side
8732 supports currently only normal server not router server yet.
8733 Some changes to NAMES definition in SILC protocol specification.
8735 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8737 * Implemented LEAVE command on client and server.
8739 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8740 again. This change was made to the protocol as well. Server
8741 should not violate the protocol specification anymore.
8743 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8745 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8746 was tested. SOCKS4 was not but should work anyway.
