544 not returned by standard WHOIS command. Defined that server
545 can send WHOIS command directly to client. Client provides
546 the requested attributes to the server. Updated the protocol
547 specs. Protocol TODO #4. Implementation is not done yet
550 * Renamed function silc_client_command_status_message to
551 silc_client_status_message. Affected files are
552 lib/silcclient/command_reply.[ch].

570 options to the server. Affected files silcd/serverconfig.[ch],
571 silcd/command.c and silcd/packet_receive.c.
573 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Added resolve_cmd_ident field to the SilcClientEntry structure
576 too so that if the entry is for example being resolved so
577 another command may attach to the same pending command reply
578 without requiring to resolve the same entry again. Added
579 support for adding multiple pending commands for one
580 command idenfier. Affected files lib/silcclient/command.[ch],
581 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
583 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
585 * Defined that server receives WHOIS command reply for private
586 and secret channels too. Updated protocol specs and the
587 code in server. Affected file silcd/command.c.
589 * Defined <channel user mode list> argument to WHOIS command
590 reply for returning user modes on the channels. The
591 channel list now doesn't include the user mode anymore but the
592 actual channel mode. Updated protocol specs and the code in
593 client and server. Affected files are silcd/command_reply.c,
594 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
595 and lib/silcclient/command_reply.c.
597 * Save the channels list in WHOIS command reply in normal server
598 so that WHOIS always shows joined channels also in normal
599 server and not just on router. Affected file is
600 silcd/command_reply.c.
602 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

612 mask to the client. Updated protocol specs and the server.
613 Affected file is silcd/command.c.
615 * Added SILC session detachment/resuming support. It is possible
616 to detach by closing the network connection and then re-connect
617 and resume to the old client session. Added DETACHED user
618 mode that server will set for detached client. Added new
619 packet RESUME_CLIENT which is used to perform the resuming
620 process. Added DETACH command. Updated the protocol specs,
621 core library, client and server. Protocol TODO #22. Very
622 many affected files around the tree.
624 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Changed the CMODE's mode mask argument to be optional. If
627 not provided then the command merely returns the current mode
628 mask to the client. Updated protocol specs and the server.
629 Affected file is silcd/command.c.
631 * Changed the Killer's Client ID in KILLED notify to be just
632 any ID payload since router server is allowed to kill as well.
633 Updated protocol specs, client libary and server. Affected
634 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
635 and irssi/src/silc/core/client_ops.c.
637 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Added new user modes ANONYMOUS for special anonymous servers
640 that may set the mode for client, and BLOCK_PRIVMSG which
641 client may set to block incoming private messages unless the
642 Private Message Key flag is set (using private keys to protect
643 private messages). Updated protocol specs and code in client
644 and server and core library. Protocol TODO #23. Affected
645 files are lib/silccore/silcmode.h, silcd/server.[ch],
646 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
647 irssi/docs/help/in/umode.in, lib/silcclient/command.c.

650 may set to itself to tell server not send channel messages.
651 Other packets such as channel key packets are still sent.
652 Protocol TODO #23. Updated the protocol specs, client and
653 server. Affected files are lib/silccore/silcmode.h,
654 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
655 lib/silcutil/silcutil.c, silcd/command.c, and
658 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Redefined the Status Payload to include now two 8 bit fields,
661 instead of one 16 bit field. This now makes it possible to
662 send list of errors. Updated the protocol specs and the code
663 in core library, client library and server. Protocol TODO #1.
664 Affected files are lib/silccore/silccommand.[ch],
665 lib/silcclient/command_reply.[ch], silcd/command.c,
666 silcd/command_reply.c and silcd/packet_receive.[ch].
668 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
670 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
671 must be handled by the application and should tell the application
672 that an error message was already printed, and it should print the
673 config coords (line, filename, ...). Affected files are
674 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
676 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
677 server config parsing code more readable.
679 Fixed a bug in the fetch_logging() config callback.
681 Affected files is silcd/serverconfig.c.
683 * Drop root privileges when started in foreground. Don't drop them

692 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
693 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
695 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Added STATS command to the protocol after all, to return
698 various statistical information about the network. It can
699 be used by clients to retrieve statistical information, and
700 servers may use it to to fetch cell and network wide
701 statistics from router. Updated the protocol specs and
702 implemented it to the server. Protocol TODO #16.
703 Affected files are lib/silccore/silccommand, silcd/command.[ch],
704 silcd/command_reply.[ch].
706 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
708 * The LIST command reply in client libary now adds new channel
709 entry if the returned channel doesn't exist yet in cache,
710 and returns the channel entry to the application in the
711 command_reply client operation. Affected file is
712 lib/silcclient/command_reply.c.
714 * Changed the channel message payload's MAC generation to
715 include the IV in the MAC as well. This way all relevant
716 parts of the channel message payload are authenticated also
717 with the channel message MAC (and not only by packet MAC).
718 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
719 Affected file is lib/silccore/silcchannel.c.
721 * Fixed the SKE to save the remote version, since the
722 silc_ske_parse_version mistakenly checked wrong version,
723 after it replaced the start payload. Affected files are
724 lib/silcske/silcske.[ch].
726 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

730 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
731 Affected files lib/silcutil/silcstrutil.[ch].
733 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
734 files are lib/silcutil/silcstrutil.[ch].
736 * Defined that the security property fields in SKE SHOULD be
737 UTF-8 encoded, defined that version string MUST be US-ASCII
738 encoded, defined that passphrases sent in connection
739 authentication protocol MUST be UTF-8 encoded. Implemented
740 these to the client and server. Defined also that other
741 passphrases sent in the protocol MUST be UTF-8 encoded.
742 Affected files are lib/silcske/silcske.c,
743 lib/silcclient/protocol.c, silcd/protocol.c,
744 silcd/serverconfig.c, and lib/silccore/silcauth.c.
746 * Changed the silc_client_close_connection interface to not
747 need the SilcSocketConnection which should not be visible
748 to application. Affected files are lib/silcclient/client.c
749 and lib/silcclient/silcclient.h.
751 * Rewrote the text for Private Message Key Payload in the
752 protocol specification. Protocol TODO #11.
754 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Upgraded the protocol version to 1.1, updated protocol specs
759 * Added the nickname as new argument to NICK_CHANGE notify and
760 added it to protocol specs and implemented it to client and
761 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
762 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
763 lib/silcclient/client_notify.c.

769 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
770 The killer's client entry is now returned to application in
771 the `notify' client operation.
773 * Fixed the Max Argument fields that had too large value set
774 in the protocol specs. Protocol TODO #14.
776 * Added the LEAVE command reply to return the ID of parted
777 channel. Updated protocol specs and implemented it to the
778 client and server. Protocol TODO #15. Affected files are
779 silcd/command.c, lib/silcclient/command_reply.c. The channel
780 entry is now returned to application in the `command_reply'
783 * Rewrote the version SKE version checking in client libary
784 and in server to use the silc_parse_version_string. Affected
785 files are lib/silcclient/protocol.c, silcd/protocol.c.
787 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
788 commands that was missing it, and updated protocol specs and
789 the server implementation. Protocol TODO #10. The affected
790 file is silcd/command.c.
792 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
793 generic reply to a generic request (REQUEST flag), and
794 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
795 way. A draft-riikonen-silc-flags-payloads-00.txt is written
796 to define the payload for DATA flag. Added the flags to
797 the implementation. Protocol TODO #9. Affected file is
798 lib/silccore/silcchannel.h.
800 Changed the client library to return the message length
801 to application as well in the channel_message and private_message
802 client operations. Affected files are
803 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
804 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
805 and lib/silcclient/client_ops_example.c.
807 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
808 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
809 the channel. Updated protocol specs and impelemented this
810 to client and server. Protocol TODO #6. Affected files are
811 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
812 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
814 Added new options m and M to CMODE command in Irssi SILC
815 client to set these modes.
817 * Deprecated all administrative commands from SILC protocol
818 since they are highly implementation specific commands.
819 Updated protocol specs. Moved the old commands in
820 implementations to private range of command types. Affected
821 files are silcd/command.c, lib/silcclient/command.c and
822 lib/silcclient/command_reply.c. Protocol TODO #8.
824 * Fixed a bug in server where sending unknown command crashes
825 the server. Affected file silcd/command.c.
827 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
829 * Added SILC_PROTOCOLVERSION macro to check protocol version
830 of a socket connection. The affected file is
831 lib/silcutil/silcsockconn.h.
833 * Added better error logging in rekey protocol. Affected file
836 * Do not check public key types in SKE during rekey. Affected
837 file lib/silcske/payload.c.
839 * Fixed the rekey protocol with PFS, which was totally broken.
840 Affected file silcd/protocol.c.
842 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
844 * Some client implementations quit network by doing first LEAVE
845 and then immediately SIGNOFF (like Bombyx). We now do check
846 after a short time after LEAVE notify and check whether the
847 client is still valid after LEAVE, and if not we remove it from
848 cache. Affected file is lib/silcclient/client_notify.c.
850 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
852 * Merged version 1.1.4 of zlib. Even if it not currently in use,
853 it's good not to have security holes here.
855 * Fixed a negative refcount situtuation for the config context.
856 Affected file is silcd/serverconfig.c.
858 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
860 * ROBOdoc documented lib/silcutil/silcutil.h.
862 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
864 * Optimized even more the SilcPacketContext structure. Now
865 totally saved 16 bytes of memory per context after optimization.
866 Affected files are lib/silccore/silcpacket.[ch].
868 * Made strict checks for valid SILC IDs. Affected file is
869 lib/silccore/silcid.c.
871 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Changed the object argument for silc_cipher_register,
874 silc_hash_register, silc_hmac_register and silc_pkcs_register
875 to const. Affected files are lib/silccrypt/silccipher.[ch],
876 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
878 * Changed the silc_get_username and silc_get_real_name to
879 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
881 * Fixed the Irssi SILC Client to use the silc_get_username and
882 silc_get_real_name insted of glib routines since the glib
883 routines only corrupt stack. Fixes the Irssi SILC to work in
884 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
886 * Fixed the Irssi to not use g_get_home_dir since it crashes
887 or returns garbage on cygwin and corrupts stack. Added function
888 get_home_dir to Irssi routines. Affected files are
889 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
891 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
893 * Made some structure optimizations. SFTP memory FS MemFSEntry
894 entry structure. Optimized SilcTask structure. Optimized
895 SilcPacketContext structure.
897 Affected files lib/silcsftp/sftp_fs_memory.c,
898 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
900 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
902 * And yet again reverted back the config thing since Johnny
903 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
906 * Fixed memory leaks from config object. Affected files are
907 silcd/serverconfig.[ch].
909 * Added support for adding new connections to the server in rehash.
910 After rehash they take effect.
912 Added support for changing the maximum allowed connections in
913 rehash. The number can grow but going smaller is not supported.
915 Added function silc_server_num_sockets_by_remote to the
916 silcd/server_util.[ch].
918 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
920 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
922 * Added preliminary checking during config parsing for a valid
923 public/private key and removed further checks in the code.
924 Affected files are silcd/serverconfig.[ch], server.c.
926 * Moved functions silc_server_drop() and silc_server_daemonise()
927 from server.c to silcd.c since they are stricly related to
928 the application activity.
930 * Reverted a small part of the automatic ref/unref since
931 it caused a double unref in some situations. Affected
932 files are silcd/silcd.[ch], server.c, serverconfig.c.
934 * Added some .cvsignore files in the lib directory.
936 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
938 * Fixed silc_net_gethostbyaddr to correctly resolve by
939 address. Affected file lib/silcutil/silcnet.c.
941 * Fixed the notify relaying to client. The HMAC to be used
942 with relayed packets ws wrong and caused decryption failure
943 at the client end. Affected file is silcd/packet_receive.c.
945 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
947 * Created new branch silc_protocol_1_0_branch.
949 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
951 * Changed the silc_server_config_* routines to be SilcServer
952 independent. They are now officially application specific code
953 and not part of generic server implementation. Affected files
954 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
956 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Added automatic referencing of config context in the
959 silc_server_config_alloc, and automatic unreferencing in the
960 silc_server_config_destroy. Affected files are
961 silcd/serverconfig.[ch], silcd/silcd.c.
963 * Fixed the silc_log_quick handling in the logging routines.
964 It didn't log quickly when it was TRUE. Affected file is
965 lib/silcutil/silclog.c. Also the flush delay was set even
966 if it was 0 in config file. Affected file is
967 silcd/serverconfig.c.
969 * Added support for changing key pair of the server in rehash.
970 Affected file silcd/server.c.
972 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Fixed the TOPIC_SET notify to not cras. It changed the topic
975 too early, before getting the channel entry. Affected file
976 is silcd/packet_receive.c.
978 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
980 * Added functions silc_server_config_[ref/unref], these are used
981 to prevent that the config object is destroyed.
983 No longer directly affect global variables silc_log_quick and
984 silc_log_delay, they are first cached inside the config object
985 and then applied with silc_server_config_setlogfiles().
987 silc_server_config_set_defaults() is now internal to
988 serverconfig.c, there are no reasons to show this internal stuff
991 Affected files are silcd/serverconfig.[ch].
993 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
994 fprintf's to stderr, since some code may be executed again after
995 the server went into the background. Affected files are
998 * Added rehash support. Added function silc_server_rehash() that
999 will perform all the basic tasks of the rehashing procedure.
1001 * Added command line option `-x, --hexdump'. This will enable the
1002 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1003 The option `--hexdump' implies `--debug'.
1005 * Fixed a bad bug in the logging APIs (silcutil library) where
1006 the application would crash after calling silc_log_reset_all().
1008 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1010 * Fixed the KICKED notify handling in client library to
1011 correctly remove the channel and all entries from the
1012 channel when I was kicked. This bug crashed the client.
1014 Fixed yet another but in KICKED notify handling to remove
1015 the kicked client correctly from the channel.
1017 Affected file is lib/silcclient/client_notify.c.
1019 * Fixed a minor bug in looking up correct client entry
1020 in KICKED notify in server. Affected file is
1021 silcd/packet_receive.c.
1023 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1024 sources correctly to distribution. Fixes --with-gmp option.
1026 * Removed the manual rehashing from ID Cache, and changed it
1027 to use the SILC Hash Table's auto rehash feature. Affected
1028 file is lib/silccore/silcidcache.c.
1030 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1032 * Fixed a bug in the silc_client_nickname_format function that
1033 handles the multiple same nickname formatting. Two clients
1034 with same nickname caused problems after the first one left
1035 and rejoined. It didn't format the nickname correctly.
1036 Affected file is lib/silcclient/idlist.c.
1038 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1040 * Don't change the topic if olod topic is same as new one.
1041 Affected file is silcd/packet_receive.c.
1043 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1045 * Added cross-reference support to the SILC Documentation
1046 generator. All types across all HTML files are now cross-
1047 referenced. Affected files util/robodoc/generator.c and
1048 scripts/silcdoc/silcdoc.
1050 * Added file lib/silcutil/silctypes.h to include all the
1051 arithmetic type definitions and some macros. Removed
1052 includes/bitmove.h and moved macros to silctypes.h.
1054 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1056 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1058 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1060 * Added `type' argument to silc_id_payload_parse_id function which
1061 now returns the type of the ID to the sent pointer. Affected
1062 file is lib/silccore/silcid.[ch].
1064 * Added check for CMODE_CHANGE notify type that mode change is
1065 allowed by the sender. Affected file silcd/packet_receive.c.
1067 * Added check for CUMODE_CHANGE notify type that mode change is
1068 allowed by the sender. Affected file silcd/packet_receive.c.
1069 Added the ID type as CUMODE_CHANGE notify type as argument
1070 to the `notify' client operation. Affected files are
1071 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1073 * Added function silc_client_add_server to the client library.
1074 Added support for resolving also channel and server info when
1075 received unknown entity in notify packet. Affected files are
1076 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1078 * Added function silc_command_get_status to return the command
1079 status from the command reply's argument payload. Affected files
1080 are lib/silccore/silccommand.[ch].
1082 * Added check for KICKED notify type that the kicking is
1083 allowed by the client. Affected file silcd/packet_receive.c.
1085 * Created function silc_get_input which can be used to get input
1086 (echo on or off) from user on command line. Affected files are
1087 lib/silcutil/silcutil.[ch].
1089 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1091 * Optimized silc_server_packet_relay_to_channel function.
1092 Added new function silc_channel_message_payload_encrypt which
1093 can be called directly if channel message payload needs to
1094 be encrypted and is already encoded (no need to call _encode
1095 function). Packet relaying is now done by router without any
1096 extra memory allocations. Affected files are
1097 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1098 silcd/packet_send.c.
1100 * Fixed the INVITE notify handling. It took wrong arguments
1101 as invite list and invite delete. Affected file is
1102 silcd/packet_receive.c.
1104 * Added check for TOPIC_SET notify type that the topic change is
1105 allowed by the client. Affected file silcd/packet_receive.c.
1107 * Added check for INVITE notify type that inviting is allowed by
1108 the client. Affected file silcd/packet_receive.c.
1110 * Changed the silc_server_client_on_channel to return the
1111 SilcChannelClientEntry as well. Moved the function
1112 silc_server_check_cmode_rights to server_util.[ch].
1113 Affected files are silcd/server_util.[ch], silcd/command.c.
1115 * Added function silc_server_check_umode_rights to check whether
1116 changing client's user mode is allowed. Added check for
1117 UMODE_CHANGE notify type that the umode change is allowed
1118 by the client. Affected files are silcd/server_util.[ch],
1119 silcd/packet_receive.c and silcd/command.c.
1121 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1123 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1124 ID length. It ignored that ID can be IPv6 based as well.
1125 Affected file lib/silccore/silcpacket.h.
1127 * Fixed the silc_id_id2str and silc_id_str2id to take the
1128 IPv6 address offset's into consideration. Affecte file is
1129 lib/silccore/silcid.c.
1131 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Fixed the internal Unix scheduler functions to check for
1134 NULL context they may receive. The affected file is
1135 lib/silcutil/unix/silcunixschedule.c.
1137 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1139 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1140 can specify different directory with --home command line
1141 parameter. Affected files irssi/src/silc/core/client_ops.c,
1144 * SILC-specific commands aren't now executed if the active server
1145 isn't of SILC-type, so there won't be problems with having
1146 IRC and SILC protocol support in same client. Affected files
1147 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1150 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * Improved the signal support in SILC Schedule. Added new
1153 function silc_schedule_signal_call which is used by application
1154 to mark a signal to be called. It is now safe to perform
1155 any kind of tasks in signal callbacks since it is guaranteed
1156 that the application specified signal callback is called
1157 after the signal is over. Affected files are
1158 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1160 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Added `name' field to SilcChannelPrivateKey to represent
1163 application given name for the key. Moved also the context from
1164 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1165 Added the `name' argument also to the function
1166 silc_client_add_channel_private_key.
1168 Added function silc_client_current_channel_private_key to set the
1169 current channel private key in use.
1171 Added "change" command to KEY command which can be used to change
1172 the current channel private key. Bound the command also to
1173 alt+K (Alt+Shift+k).
1175 Also affected files lib/silcclient/client_channel.c,
1176 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1178 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1180 * Added silc_rng_get_byte_fast function in to the
1181 lib/silccrypt/silcrng.[ch].
1183 * Changed the interface of silc_packet_assemble and the
1184 silc_packet_send_prepare. If silc_packet_assmble is now
1185 called the application does not call silc_packet_send_prepare
1186 because the library will call it automatically. These
1187 interfaces now also return a reference to the outgoing buffer
1188 which includes the assembled packet, which the application can
1189 use to encrypt the packet.
1191 Affected files are lib/silccore/silcpacket.[ch],
1192 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1193 silcd/packet_send.c, server_backup.c and packet_receive.c.
1195 * Fixed a packet sending bug on very high load, where outgoing
1196 packet queue wasn't handled correctly and packets got corrupted.
1197 Affected files are lib/silcutil/*/silc*sockconn.c,
1198 lib/silcclient/client.c and silcd/server.c.
1200 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1202 * Added macro SILC_PACKET_DATALEN which can be used during
1203 packet assembling to check whether the data to be added to
1204 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1205 len is truncated until it fits it.
1207 Added checks for maximum length of channel message payload and
1208 private message payload also.
1210 Added checks for maximum packet length in server and in
1213 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1214 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1215 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1216 lib/silcclient/client_prvmsg.c.
1218 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Added silc_server_packet_queue_purge call to the
1221 silc_server_disconnect_remote to assure that all data in the
1222 queue before disconnecting is sent to the network. Affected
1223 file silcd/server.c.
1225 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1227 * Added the deleting of server's own ID cache entry to the
1228 silc_server_free function. Free also everything else that
1229 has been allocated in silc_server_init. The affected file
1232 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1234 * Added functions silc_parse_version_string, silc_version_to_num,
1235 and silc_ske_parse_version to parse SILC protocol style version
1236 strings. Affected files lib/silcutil/silcutil.[ch] and
1237 lib/silcske/silcske.[ch].
1239 * Added new configuration params: version_protocol, version_software
1240 and version_software_vendor to specify what version the remote
1241 host must at least be to be able to connect to server. The vendor
1242 string can be regex matched too. Added new function
1243 silc_server_connection_allowed to check maximum number of allowed
1244 connections, and allowed versions for incoming connections.
1245 Affected files are silcd/server.c, server_util.[ch] and
1248 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1250 * Added preliminary support for signals in scheduler. The
1251 signals we care about are now blocked always when the scheduler
1252 is locked. This way we can synchronise the use of signal with
1253 scheduler. It is guaranteed that when signal occurs the scheduler
1254 is not locked, and thus new tasks can be safely added to the
1257 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1258 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1259 Added new platform specific routines
1260 silc_schedule_internal_signals_[un]block and
1261 silc_schedule_internal_signal_[un]register.
1263 Added new functions to SILC Schedule API:
1264 silc_schedule_signal_[un]register. Each signal that application
1265 is going to use should be registered to the scheduler.
1267 Affected files are lib/silcutil/silcschedule.[ch],
1268 lib/silcutil/*/silc*schedule.c.
1270 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Check for unauthenticated client and server in the
1273 silc_server_new_client and silc_server_new_server functions.
1274 Affected file silcd/packet_receive.c.
1276 * Added function silc_string_is_ascii to check whether given
1277 string is 7-bit ASCII string. Affected files are
1278 lib/silcutil/silcutil.[ch].
1280 * Added function silc_id_is_valid_server_id into the
1281 silcd/serverid.c and added checking for valid Server ID's in
1282 silc_server_new_server. The Server ID must always be based
1283 on the server's public IP address.
1285 * Added logging of DISCONNECT packet message in the server.
1286 Affected file silcd/server.c.
1288 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1290 * Changed all library interfaces that use Global RNG to also
1291 accept SilcRng as argument. Affected files are
1292 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1293 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1294 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1295 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1296 lib/silccrypt/rsa.c.
1298 * Added function silc_pkcs_generate_key to the
1299 lib/silccrypt/silcpkcs.[ch] for applications so that they
1300 don't need to do pkcs->pkcs->init calls anymore.
1302 * Remove SilcSocketConnection from the SFTP API since it really
1303 wasn't needed there. The application has the information
1304 saved in its contexts anyway and the SFTP layer doesn't need
1305 know about it. Affected files lib/silcsft/silcsftp.h and
1306 lib/silcsftp/sftp_[server/client].c.
1308 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1309 The SilcSimContext is not SilcSim.
1311 * Fixed possible buffer overflows in silc_id_render in the
1312 lib/silcutil/silcutil.c.
1314 * On EPOC the global crypto module lists are not used at all
1315 in the crypto library. Added support for using the constant
1316 algorithm list on EPOC. Affected files are
1317 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1320 * Fixed the handling of third parameter of KICKED notify, since
1321 it was mistakenly updated to SILC Protocol 1.0 even though it
1322 is to be included in 1.1. Since it is not in 1.0 it is not
1323 mandatory, and this fix now handles it only if it is provided,
1324 and it is not error if it is not provided. Affected file
1325 lib/silcclient/client_notify.c.
1327 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1329 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1330 client. Affected file irssi/src/silc/core/client_ops.c.
1332 * Merged with Irssi 0.8.4 from irssi.org CVS.
1334 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Check for valid socket connection in client entries before
1337 sending any messages. Fixes a crash, but doesn't fix some
1338 other underlaying bug that is lurking there. Affected
1339 file silcd/packet_send.c.
1341 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1343 * $usermode, $cumode and $cumode_space expandos shouldn't do
1344 anything with non-SILC server records. Affected file
1345 irssi/src/silc/core/silc-expandos.c
1347 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1349 * Fixed the silc_net_check_[host/local]_by_sock to support
1350 IPv6 bound sockets as well. Now they can return IPv6 addresses
1351 as well. Affected file lib/silcutil/silcnet.c.
1353 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1354 Affected lib/silcutil/unix/silcunixnet.c.
1356 * Fixed ID rendering (at least on some platforms, not NetBSD)
1357 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1359 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Added silc_hash_public_key and silc_hash_public_key_compare
1362 functions to be used with SilcHashTable. They can be used to
1363 hash public keys and compare public keys in hash table. Affected
1364 file lib/silcutil/silcutil.[ch].
1366 * Added support for specifying multiple public keys for Client
1367 connection section in server configuration file. This makes it
1368 possible to accept multiple public keys from same host, or to
1369 make a section that accepts any incoming host, and have the
1370 accepted public keys listed in the section.
1372 Added functions silc_sever_[find/get]_public_key, added the
1373 support for this actually to all connection sections but only
1374 the Client section is currently allowed to specify multiple
1377 Affected files are silcd/server.c, server_internal.h,
1378 command.c, protocol.c, server_util.[ch], packet_receive.c.
1380 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1382 * Merged Irssi 0.8.2 from irssi.org CVS.
1384 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1386 * If silc_debug is TRUE, also output standard logging messages
1387 to stderr with the debug output.
1389 Made silc_log_reset_all() flushing all channels before returning.
1390 Also fixed some documentation typos.
1392 Affected files are lib/silcutil/silclog.[ch].
1394 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1396 * Fixed the server to check correctly the amount of connections
1397 from single host, by checking also the type of the connection.
1398 Fixed also the comparison of number of connections and number
1399 of allowed connections. Affected files are silcd/server.c,
1402 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1404 * Fixed the USERS command reply to save the user's mode on the
1405 channel as well. Fixed JOIN command reply to check whether a
1406 client is on channel already and not join it twice. Affected
1407 file lib/silcclient/command_reply.c.
1409 * Added new file silc-expandos.c into irssi/silc/core/ to return
1410 various stuff for various signal for the statusbar etc. updating.
1411 Now Irssi SILC client prints channel user modes etc. on the
1414 * The user mode (like server/router operator changes) is now shown
1415 on the Irssi SILC client's statusbar. The affected files are
1416 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1418 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1420 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1421 to SILC_SCHEDULE_[UN]LOCK macros.
1423 * Added more error printing to logs in server code. Affected
1424 files silcd/server.c and silcd/protocol.c.
1426 * Fixed -S option parsing in Irssi SILC Client. Affected file
1427 irssi/src/silc/core/silc-core.c.
1429 * Added silc_buffer_alloc_size function. Affected file is
1430 lib/silcutil/silcbuffer.h.
1432 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1435 constants. Affected files in
1436 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1439 * Changed the internal SFTP Memory FS table to const. Affected
1440 file lib/silcsftp/sftp_fs_memory.c.
1442 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed the buffer formatting and unformatting routines to
1445 check the size of 64 bits types with sizeof(). Affected
1446 file is lib/silcutil/silcbuffmt.c.
1448 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1450 * Removed 0.6.x backwards support.
1452 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1454 * Changed all integer type names:
1455 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1456 to avoid collisions with other libraries using same type names
1459 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1461 * Added `prefer_ipv6' argument to the functions
1462 silc_net_gethostbyname[_async]. If it is TRUE it will return
1463 IPv6 address over IPv4. If FALSE IPv4 address is returned
1464 even if IPv6 address was found. Affected files
1465 lib/silcutil/silcnet.[ch].
1467 * Added support silc_net_create_connection[_async] to fallback
1468 to IPv4 address if IPv6 address could not be used (like if
1469 it doesn't work on a specific system). Affected file in
1470 lib/silcutil/unix/silcunixnet.c.
1472 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1474 * Added silc_schedule_reinit function to do the enlarging
1475 of the max tasks handling capabilities of the scheduler.
1476 Affected files lib/silcutil/silcschedule.[ch].
1478 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1480 * Added automatic extern "C" { ... } for C++ compilers so the
1481 application does not need to define them. Affected file
1482 includes/silcincludes.h.
1484 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1485 old name went against naming convention. Applications now
1486 include "silcclient.h" instead of "clientlibincludes.h".
1487 Removed includes/clientlibincludes.h, it is redundant now.
1489 * Renamed includes/version.h to silcversion.h.
1491 * Added really preliminary support for OS/2 into the util
1492 library. Only thread & mutex API is implemented, others
1493 are still to be implemented. Created the lib/silcutil/os2/
1494 directory. Created also file includes/silcos2.h.
1496 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1498 * Added preliminary BeOS support into the util library.
1499 Created lib/silcutil/beos/, and implemented all the needed
1500 functions to support SILC on BeOS. Created also file
1501 includes/silcbeos.h.
1503 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1505 * Added proper initializations to silc's irssi code, so it's
1506 now possible to load it as module. Affected files
1507 irssi/src/silc/core/silc-core.c,
1508 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1510 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1512 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1515 * Fixed the silcdoc document generator to correct generate
1516 docs from all kinds of filenames. Affected files are
1517 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1519 * ROBOdoc documented lib/silcutil/silcmemory.h.
1520 Added also new function silc_memdup.
1522 * Removed lib/silcutil/silcbufutil.h and moved those routines
1523 to the lib/silcutil/silcbuffer.h.
1525 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1527 * Added `user_count' to the SilcChannelEntry which now tells the
1528 number of users on the channel. The user count is now saved
1529 in normal server of global channels as well. Affected files
1530 silcd/server.c, idlist.h, packet_receive.c and command.c.
1532 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1533 include file utility functions.
1535 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1536 instead of calling directly OS routines.
1538 * Fixed NICK change printing in Irssi SILC Client. Fixed
1539 KICKED notify printing in Irssi SILC Client. Affected file
1540 irssi/src/silc/core/client_ops.c.
1542 * Fixed a NICK change bug in client library, to not recreate the

1548 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1549 the SKE interface a bit.
1551 * Fixed padding problem in PKCS#1. The padding was not actually
1552 random since the random number generator was used incorrectly.
1553 This security bug affects only when encrypting with PKCS#1, and
1554 it is not currently used at all in SILC. SILC only use signing
1555 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1557 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1564 little timeout after connecting. The affected file is
1565 lib/silcclient/client.c.
1567 * Added following new config file settings:
1568 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1569 key_exchange_timeout, conn_auth_timeout, connections_max,
1572 Implemented all the new config settings handling in the server.
1574 Optimized the use of SKE Mutual flag usage. Use it only
1575 if connection authentication protocol is not based in public
1578 Renamed all SilcServerConfigSection* to SilcServerConfig*
1579 to have a bit shorter names.
1581 Affected files silcd/serverconfig.[ch], server.[ch], and
1584 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1610 Affected files are silcd/serverconfig.[ch].
1612 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1614 * Fixed command line parameter handling. All SILC initialization
1615 is now done in silc_core_init() which also fixes autoconnecting
1618 Affected files irssi/src/silc/core/silc-core.c,
1619 irssi/src/fe-text/silc.c.
1621 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1623 * Added new configuration options and blocks:
1624 keepalive_secs, reconnect_count, reconnect_interval,
1625 reconnect_interval_max, reconnect_keep_trying and
1626 require_reverser_lookup. Added ConnectionParam block, and
1627 implemented the connection parameters when connecting as
1628 initiator and when accepting connections as responder.

1631 whether given configuration value has been given already.
1633 Affected files silcd/serverconfig.[c], server.[c].
1635 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1636 algorithm parts and created new file silcalgs.conf, that
1637 is now included from the example_silcd.conf.in.
1639 * Optimized the silc_server_connect_to_router_second to take
1640 the connection configuration object from the SilcServerConnection
1641 object instead of finding it during the connecting phase.
1642 Added the configuration object to SilcServerConnection struct.
1643 Affected files silcd/server_internal.h, server.c.
1645 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1647 * Add the client on channel after it was resolved at the
1648 channel message receiving, and it was not already on the
1649 channel. Affected file lib/silcclient/client_channel.c.
1651 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1653 * Fixed the public key authentication to allocate always the
1654 destination signature buffer instead of using static buffer.
1655 Affected file silcd/protocol.c.
1657 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1665 * Added new Passphrase and Publickey authentication methods to
1666 config file, allowing both public key and passphrase based
1667 authentication to be set at the same time.
1669 Added `prefer_passphrase_auth' setting in config file which
1670 can be used to set to prefer passwd auth if both passwd and
1671 public key is set. If not set, public key is preferred.
1672 This has effect only when being initiator (responder will try
1675 Added support for authentication with passphrase and public key
1676 at the same time. The passphrase is tried first always since
1677 it is faster to check.
1679 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1681 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1683 * Merged the new SILC Config library, with the server parsing
1684 support. Read the header file silcconfig.h or the toolkit
1685 documentation for the news. Affected files are

1708 Payload. Affected file lib/silccore/silcchannel.c.
1710 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1711 as header filenames.
1713 * Removed lib/silcclient/README and created HTML file
1714 lib/silcclient/silcclient_using.html, which is now included
1715 as part of Toolkit documentation.
1717 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1719 * Fixed CUMODE_CHANGE notify handling to change the mode of
1720 correct client. Affected file lib/silcclient/client_notify.c.
1722 * Make silc_rng_alloc fail if it cannot allocate the sha1
1723 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1727 * Fixed the file transfer's key agreement payload to include
1728 zero port also if the hostname is NULL because it could not
1731 Call file transfer monitor callback now also if error occurs
1732 during key agreement protocol.
1734 Changed the silc_client_file_send interface to return the
1735 SilcClientFileError instead of session id. The session ID
1736 is returned into pointer provided as argument.
1738 Check that the file exists locally before sending the
1739 file transfer request at all.
1741 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1743 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1744 error than can occur while key agreement protocol. Affected
1745 file lib/silcclient/silcapi.h.
1747 * Fixed the event_mode CMODE handler to not crash when mode
1748 is changed and +k mode is set in the channel. Affected file
1749 irssi/src/silc/core/silc-channels.c.
1751 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1752 SILC_LOG_WARNING to give out Warning and not Error. Affected
1753 file lib/silcutil/silclog.c.
1755 * Fixed the channel message payload decryption in the function
1756 silc_channel_message_payload_decrypt to not modify the original
1757 buffer before it is verified that the message decrypted
1758 correctly. Otherwise, next time it is called with correct
1759 channel key it won't encrypt since the payload is corrupted.
1760 Affected file lib/silccore/silcchannel.c.
1762 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1774 * Fixed a bug in hash table internal routine for traversing
1775 the table with foreach callback. The current entry may
1776 become invalid in the callback but it was referenced after
1777 the callback returned.
1779 Do not allow auto rehashing of hash table during the
1780 silc_hash_table_foreach operation, for same reasons as it is
1781 not allowed for SilcHashTableList. Affected files are
1782 lib/silcutil/silchashtable.[ch].
1784 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1787 Win32 DLL. extern's in header files are now declared with
1790 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Fixed private message handling. It used some old code that
1793 caused the client to crash. Affecte file is
1794 lib/silcclient/client_prvmsg.c.
1796 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1798 * Added function silc_client_add_channel,
1799 silc_client_replace_channel_id, and removed functions
1800 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1801 from client library.
1803 * Added cross reference of the joined channels to the
1804 SilcClientEntry, and changed the SilcChannelEntry's
1805 users list to SilcHashTable. The affected files are
1806 lib/silcclient/idlist.[ch].
1808 * Fixed a bug in hash table tarversing. While the hash table
1809 is traversed with SilcHashTableList the table must not be
1810 rehashed. It is now guaranteed that auto rehashable tables
1811 are not rehashed while tarversing the list. Also defined that
1812 silc_hash_table_rehash must not be called while tarversing
1813 the table. Added function silc_hash_table_list_reset that must
1814 be called after the tarversing is over. The affected files are
1815 lib/silcutil/silchashtable.[ch].
1817 * Changed all hash table traversing to call the new
1818 silc_hash_table_list_reset in server and in client library.
1820 * Added function silc_client_on_channel to return the
1821 SilcChannelUser entry if the specified client entry is joined
1822 on the specified channel. This is exported to application as
1823 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1825 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1827 * Fixed founder regaining problem with JOIN command on normal
1828 server. The notify for mode change must be sent always and
1829 not only if !cmd->pending. Affected file silcd/command.c.
1831 * Fixed the WHOWAS command's reply sending to support the
1832 lists correctly. Affected file silcd/command.c.
1834 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1836 * When sending JOIN command to router for processing the
1837 sender's old command identifier was not saved back to the
1838 sender's command context, fixed now. The affected file is
1841 * Create the key in JOIN command of the router did not return
1842 the channel key, added check for this. Affected file is
1845 * Fixed a channel ID update bug in JOIN command reply. Do
1846 not directly upgrade the ID but call the function
1847 silc_idlist_replace_channel_id if the ID was changed.
1848 Affected file silcd/command_reply.c.
1850 * Fixed memory leaks from command calling if it would fail.
1851 Affected file silcd/command.c.
1853 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1863 * Removed TRQ from lib/trq, not needed anymore.
1865 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1866 with server connections. Later this will be configurable
1867 in config file after new config file is done. Affected file
1870 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1872 * Fixed a crash in server related to channel announcements.
1873 Affected file silcd/server.c.
1875 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1877 * Fixed memory leaks in silc_server_create_new_channel*
1878 functions. Affected file silcd/server.c.
1880 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1881 which ID was changed. This way the router will send the
1882 user list for the channel again, and server won't be in
1883 desync in some rare circumstances. Affected file is
1884 silcd/packet_receive.c.
1886 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1888 * Check for NULL socket pointer in the function

1898 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1900 * Added lib/silcclient/client_ops_example.h as an template
1901 file for application programmers to quickly start using
1902 the SilcClientOperation functions in their application.
1903 Updated the lib/silcclient/README as well to tell about this
1904 nice file made available.
1906 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1908 * Call silc_server_remove_from_channels when removing client
1909 entry when NO_SUCH_CLIENT_ID was received. Affected file
1910 is silcd/command_reply.c.
1912 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1914 * Added server & router operator statistics updating. Affected
1915 file silcd/packet_receive.c and silcd/command.c.
1917 * Fixed the SERVER_SIGNOFF notify handling on normal server
1918 not to save the history information for clients. Same was
1919 fixed earlier in remove_clients_by_server function, but not
1920 here. Affected file silcd/packet_receive.c.
1922 * Raised the default connection-retry count from 4 to 7 in
1923 server. Affected file silcd/server.h.
1925 * Cancel any possible reconnect timeouts when we start the
1926 key exchange. Affected file silcd/server.c.
1928 * Do not reconnect on connection failure when SCONNECT was
1929 given. Affected files silcd/server.[ch].
1931 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1933 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1935 * Fixed the NICK command to always give the unformatted
1936 nickname to the one giving the NICK command. If unformatted
1937 nickname is cached already it will be formatted and the
1938 local entry will always get the unformatted nickname.
1939 Affected file lib/silcclient/idlist.c.
1941 * Fixed some double frees from client library commands.
1942 Affected file is lib/silcclient/command.c.
1944 * Fixed CUMODE command in server to assure that no one can
1945 change founder's mode than the founder itself, there was a
1946 little bug. Affected file silcd/command.c.
1948 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1950 * Removed the SilcClientCommandDestructor from the client
1951 libary, it is not needed anymore. Affected files are
1952 lib/silcclient/silcapi.h, command[_reply].[ch],
1953 client_notify, idlist.c.
1955 * Fixed GETKEY command to first resolve client, and then
1956 resolve the server only if the client was not found, instead
1957 of resolving both at the same time. Affected file is
1958 lib/silcclient/command.c.
1960 * Added silc_client_start_key_exchange_cb and lookup the
1961 remote hostname and IP address before starting the key
1962 exchange with server. The affected file is
1963 lib/silcclient/client.c.
1965 * The server's public key is now saved using the IP address
1966 of the server and not the servername for the filename.
1967 The hostname public key filename is checked as an fall back
1968 method if the IP address based filename is not found.
1970 Fixed the GETKEY command to save the fetched server key
1971 in correct filename.
1973 Print the remote server's hostname now when new key is
1974 received during connection process. Affected file is
1975 irssi/src/silc/core/client_ops.c.
1977 * Return always our own public key to the client if it asks
1978 for it with GETKEY command. Affected file silcd/command.c.
1980 * Removed the use_auto_addr variable from default config
1981 file since it was in wrong section. Affected file is
1984 * Fixed TOPIC_CHANGE notification to not route it when it
1985 was sent using silc_server_send_notify_to_channel function.
1986 Affected file silcd/command.c.
1988 * Fixed silc_server_send_notify_kicked to send the kicker's
1989 Client ID also, it was missing. Affected files are
1990 silcd/command.c, silcd/packet_send.[ch].
1992 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1994 * Do not save client history information in SERVER_SIGNOFF.
1995 Fixes the bug in normal server that it does not detect
1996 the client becoming valid after the server becomes back
1997 online. Affected file silcd/server_util.c.
1999 * Added `sock_error' field into the SilcSocketConnection
2000 context. When error occurs during socket operation (read
2001 or write) the error is saved. Added also new function
2002 silc_socket_get_error to return human readable socket error
2003 message. Affected files are lib/silcutil/silcsockconn.[ch],
2004 lib/silcutil/unix/silcunixsockconn.c, and
2005 lib/silcutil/win32/silcwin32sockconn.c.
2007 * The server now prints the socket error message in the
2008 signoff for client. Affected file silcd/server.c.
2010 * Fixed the `created' channel information sending from router
2011 to server in JOIN command. Checks now whether the channel
2012 really was created or not and set it according that.
2014 Fixed the JOIN command to use the client entry's current
2015 ID during the joining procedure instead of the one it sent
2016 in the command (it is checked though), since it can change
2017 between the packet processing and command processing, and
2018 would just case unnecessary pain in the client end. Affected
2019 file silcd/command.c.
2021 * Fixed a channel key payload sending to use correct channel
2022 ID when the server was forced to change the channel's ID by
2023 router. Router sent the key payload with the old Channel ID.
2024 Affected file silcd/packet_receive.c.
2026 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2028 * Call silc_server_save_channel_key only if the key payload
2029 was provided in the JOIN command's command reply. Affected
2030 file silcd/command_reply.c.
2032 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2034 * Fixed silc_mp_sizeinbase to return the value correctly with
2035 MPI. Affected file lib/silcmath/mp_mpi.c.
2037 * Fixed the stop_server signal to correctly stop the scheduler
2038 and gracefully stop the server when SIGTERM or SIGINT signals
2039 are received. Affected file silcd/silcd.c.
2041 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2043 * Simple handling of TERM and HUP signals. Also added some log
2044 flushing call around. Affected file is
2047 * Fixed small bugs in silclog.c. Now buffering output will take
2048 effect after 10 seconds since startup: This will ensure that
2049 no important startup messages are lost. Also output redirection
2050 will preserve original format ([Date] [Type] message).
2051 Affected file is lib/silcutil/silclog.c.
2053 * Added two options to the config file, in the logging section:
2054 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2055 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2057 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2059 * Do not print the warning about log files not being initialized
2060 more than once to avoid excess logging. Affected file is
2061 lib/silcutil/silclog.c.
2063 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2064 the SIM copying in make install in Makefile.am.pre.
2066 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2068 * Rewritten silclog APIs. Globally interesting changes follows:
2069 silc_log_set_files() changed to silc_log_set_file().
2070 silc_log_set_callbacks() changed to silc_log_set_callback().
2071 ROBOdoc documented silclog header file.
2072 SilcLogCb now returns bool to wether inihibit the default
2073 handler or not (to keep the old behaviour return always TRUE).
2074 The new APIs should also fix the problem of the
2075 silcd_error.log file that was written in the current directory.
2078 Log files streams will remain opened after silc_log_set_file()
2079 call, means less CPU usage notably on high traffic servers.
2080 File streams are now full buffered, and flushed to the disk
2081 every 5 minutes, lesses HD activity and CPU usage.
2082 Messages can be redirected, allowing admins to configure
2083 one single logfile for all server messages.
2084 the silc_log_quick global variable to activate fast-logging.
2085 Affected files lib/silcutil/silclog.[ch]
2087 * Changed some code to conform new silclog APIs. Affected
2088 files are doc/example_silcd.conf.in, silcd/server.c
2089 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2092 * Fixed a memory leak that could occur in some situations.
2093 Affected file silcd/serverconfig.c.
2095 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2097 * Added the silc_client_del_client to remove the client from
2098 all channels as well. Affected file lib/silcclient/idlist.c.
2100 * Fixed the client library to correctly remove the client
2101 from all channels when the client entry is being destroyed.
2102 Affected file lib/silcclient/client_notify.c, command.c.
2104 * Added auto-nicking support to the client library. If the
2105 applicatio now sets client->nickname it will be sent to the
2106 server after connecting by the library. This way for example
2107 SILCNICK (or IRCNICK) environment variables will have effect
2108 and always change the nickname automatically to whatever
2109 it is wanted. Affected file lib/silcclient/client.[ch].
2111 * Renamed silc_server_command_bad_chars to the
2112 silc_server_name_bad_chars and moved it to the
2113 silcd/server_util.[ch]. Added also new function
2114 silc_server_name_modify_bad to return nickname that
2115 includes bad characters as new nickname without those
2116 bad characters. This check and modify is now used in
2117 silc_server_new_client when the username is initially set
2118 as nickname, so it must be checked to be valid nickname.
2119 Affected file silcd/packet_receive.c.
2121 * The nickname length is now taken from the packet for real
2122 and not trusted to strlen() since it clearly can return
2123 wrong length for nickname including bad characters. This
2124 also applies to channel names. Affected file silcd/command.c.
2126 * Removed the lib/silcsilm/modules directory. Modules are now
2127 compiled into the lib/silcsim. Fixed the copying of the
2128 modules to follow symbolic links in Makefile.am.pre.
2130 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2132 * Fixed silc_string_regexify list creation. Fixes bugs with
2133 BAN and INVITE commands in server. The affected file is
2134 lib/silcutil/unix/silcunixutil.c.
2136 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Removed the command destructor entirely from the server's
2139 command and command reply routines. It is not needed, and
2140 its usage was buggy and caused crashes. Affected files are
2141 silcd/command[_reply].[ch].
2143 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Cancel protocol and NULL sock->protocol if timeout
2146 occurred during protocol. Affected file silcd/server.c.
2148 * Cancel protocol timeouts always before calling the final
2149 callback, to assure that after final callback is called
2150 no other state will be called for the protocol anymore.
2151 Affected file silcd/protocol.c.
2153 * Print error log if incoming connection configuration could
2154 not be found. Affected file silcd/server.c.
2156 * Fixed JOIN command to correctly save the founder mode
2157 to the client on normal SILC server, when the channel
2158 was created by the router. Affected file silcd/command.c.
2160 * Fixed LIST command (hopefully) to send correct reply
2161 packets. Affected file silcd/command.c.
2163 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * The silc_packet_receive_process now returns FALSE if the
2166 read data was invalid packet, and TRUE if it was ok.
2168 The server now checks that if unauthenticated connection
2169 sends data and its processing fails the server will close
2170 the connection since it could be a malicious flooder.
2172 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2174 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Make sure the warning about error opening a log file is
2177 printed only once and not everytime it fails (produces
2178 too much useless log). Affected file lib/silcutil/silclog.c.
2180 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2182 * Made the silc_server_daemonise() function more readable.
2183 Affected file silcd/server.c.
2185 * Pid file is now optional, the user may comment it out from
2186 the config file. Removed define SILC_SERVER_PID_FILE, we
2187 don't need a default any longer. Affected file
2188 configure.in.pre, lib/Makefile.am.pre.
2190 * Make some use of the pid file. The server now dies at startup
2191 if it detects a valid pid file on his path. The server would
2192 die anyway in this circumstance, because of the bind() failure.
2193 Affected file silcd/silcd.c.
2195 * No longer compiling lib/dotconf.
2197 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Fixed JOIN command parsing not to crash. Affected file
2200 lib/silcclient/command.c.
2202 * Fied the NICK_CHANGE notify to add the new client entry
2203 even it is resolved. This removes an <[unknown]> nick
2204 thingy bug in the client. Affected file is
2205 lib/silcclient/client_notify.c.
2207 * Do not try to allocate 0 bytes (efence does not like it)
2208 in lib/silccore/silccomand.c when encoding payload.
2210 * Do not take IRCNICK as nickname in Irssi SILC client since
2211 it is not possible to set nickname before hand connecting
2212 the server (TODO has an entry about adding auto-nicking
2215 * Changed the silc_server_command_pending to check whether
2216 there already exists an pending entry with the specified
2217 command, command identifier and pending callback. This is
2218 to fix IDENTIFY and WHOIS related crashes that may register
2219 multiple pending commands with same identifier. Affected
2220 file silcd/command.c.
2222 * Fixed the server to reconnect to the router even if it
2223 was already reconnecting and EOF was received. This to
2224 fix a possibility that the server wouldn't ever try to
2225 auto-reconnect to the router. Affected file silcd/server.c.
2227 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Fixed the server's password authentication to use the
2230 length of the locally saved password, and not the one
2231 sent in the packet. Affected file silcd/protocol.c.
2233 * Fixed same password authentication problem in the
2234 Authentication Payload handling routines in
2235 lib/silccore/silcauth.c.
2237 * Yet another password authentication problem fixed with
2238 channel password handling in silcd/command.c.
2240 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * If first character of string in silc_parse_userfqdn is '@'
2243 then do not parse it. Affected file is
2244 lib/silcutil/silcutil.c.
2246 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Fixed minor bug in IDENTIFY command reply sending, which
2249 caused various weird problems during JOIN when it was
2250 resolving names for users. Affected file silcd/command.c.
2252 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Fixed the IDENTIFY command reply sending to chech better valid
2255 clients. It was possible to send incomplete list of replies.
2256 Affected file silcd/command.c.
2258 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Added silc_client_command[s]_[un]register functions now to
2261 dynamically register the commands in client library. Removed
2262 the static table of commands. This allows the client library
2263 to call commands without causing the application to know about
2264 what commands library has called.
2266 Removed the INFO command reply kludge to detect when the command
2267 was called by library. Now library use its own command reply
2268 function for INFO command.
2270 Added function silc_client_command_call to call a command.
2271 Application can use it to call command, not access the structure
2274 Now all commands that are sent by the client library (not
2275 explicitly sent by application) use own command reply functions.
2277 Affected files around lib/silcclient/ and in
2278 irssi/src/silc/core/.
2280 * Fixed the WHOIS command reply sending to chech better valid
2281 clients. It was possible to send incomplete list of replies.
2283 Fixed the WHOIS and IDENTIFY to send the request to router
2284 if normal server did not do it and did not find any results.
2286 Affected file silcd/command.c.
2288 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Moved the internal data from SilcClient context into its
2291 own file, not accesible to application. Affected files
2292 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2293 and other files in client library.
2295 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Added doc/examples installation target in Makefile.am.pre.
2300 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2303 commands the found client entry will be removed from the
2304 cache, after notifying application about the error. Affected
2305 file lib/silcclient/command_reply.c.
2307 * Changed the /MSG to check for exact nickname user gave, and
2308 not let `nick' match `nick@host' if it is only one found. Now,
2309 user must type the exact nickname (like nick@host2) even if
2310 there are no more than one same nicks found. This is to avoid
2311 a possibility of sending nickname to wrong nickname since
2312 `nick' could match `nick@host'. Affected file is
2313 irssi/src/core/silc-servers.c.
2315 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Do not print "you are now server operator" or similar when
2318 giving /away command. Affected files are
2319 irssi/src/silc/core/client_ops.c, silc-servers.h.
2321 * Made the silc_server_command_pending_error_check to send
2322 the same command reply payload it received back to the
2323 original sender of the command. This way all arguments
2324 that was received by the server will be received by the
2325 client too. Affected file silcd/command.c.
2327 * Added the silc_idcache_add to return the created cache entry
2328 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2330 * Add global clients to expire if they are not on any channel.
2331 This is because normal server will never know if they signoff
2332 if they are not on any channel. The cache expiry will take
2333 case of these entries. This is done by normal servers only.
2334 The affected files are silcd/command_reply.c,
2335 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2337 * If server receives invalid ID notification for WHOIS or
2338 IDENTIFY and the ID exists in the lists, it is removed.
2339 Affected file silcd/command_reply.c.
2341 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2342 in client then client entry that it matches is searched and
2343 the nickname is printed on the screen for user. Affected
2344 file irssi/src/silc/core/client_ops.c.
2346 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Use cache entry expire time in the LIST command reply to
2349 purge old entries from the cache after the LIST command
2350 reply has been received. This way we don't have non-existent
2351 entries in the cache for too long. Affected file is
2352 silcd/command_reply.c.
2354 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * If we are normal server, and we've not resolved client info
2357 in WHOIS or IDENTIFY from router, and it is global client,
2358 we'll check whether it is on some channel. If it is not
2359 then we cannot be sure about its validity and will resolve it
2360 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2361 file silcd/command.c.
2363 * Search channel by name (if possible) rather than by ID
2364 in IDENTIFY command's command reply. Affected file is
2365 silcd/command_reply.c.
2367 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2370 Updated specs and implemented it. Affected file silcd/command.c,
2371 silcd/packet_send.c and silcd/packet_receive.c.
2373 * Implemented the <founder auth> payload handling in the JOIN
2374 command. If provided all conditions for channel joining
2375 except requirement to provide correct passphrase can be
2376 overrided by the channel founder. Updated the protocol specs.
2377 Affected file silcd/command.c.
2379 Added support for founder auth in JOIN command in client
2380 library. Fixed the parsing of the JOIN command now to support
2381 all options as they should be. The affected file is
2382 lib/silcclient/command.c.
2384 * Optimized the WHOIS and IDENTIFY commands to send the request
2385 to router only if it includes nicknames or other names. If
2386 they include only IDs then check the local cache first before
2387 routing. Affected file is silcd/command.c.
2389 * Added channels topic announcements. Affected file is
2390 silcd/packet_receive.c and silcd/server.c.
2392 * Fixed the silc_server_send_notify_topic_set to really destine
2393 the packet to channel. Affected file silcd/packet_send.c.
2395 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2396 library. Affected file lib/silcclient/client_notify.c.
2398 * Added UMODE announcements. Affected file silcd/server.c.
2400 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Memory leak fixes in:
2404 lib/silcutil/silcsockconn.c
2405 lib/silcske/silcske.c
2406 lib/silcske/groups.c
2408 lib/silccrypt/silcpkcs.c
2409 lib/silccore/silccommand.c
2410 lib/silccore/silcidcache.c
2415 * ROBOdoc documented the lib/silcske/groups.h file and a
2416 bit changed the interface for better.
2418 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2420 * Update the client entry context in the ID cache after
2421 nick change. Affected file lib/silcclient/command.c.
2422 Fixes the CUMODE command when regaining founder privileges,
2423 and a little WHOIS problem.
2425 * Fixed silc_net_gethostbyname to correctly call the
2426 inet_ntop. Affected file lib/silcutil/silcnet.c.
2428 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2430 * Added IPv6 support checking to the configure.in.pre, added
2431 also --enable-ipv6 option to override the check. Affected
2432 file configure.in.pre.
2434 * The silc_thread_create now calls the start function
2435 directly if threads support is not compiled in. Removes
2436 ugly #ifdef's from generic code. Affected files are
2437 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2439 * Added silc_net_gethostby[name/addr]_async to asynchronously
2440 resolve. Affected files are lib/silcutil/silcnet.[ch].
2442 * Added support for rendering IPv6 based server, client and
2443 channel IDs. Affected file lib/silcutil/silcutil.c.
2445 * Added support for creating IPv6 based server IDs. Affected
2446 file is silcd/serverid.c.
2448 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2450 * Added silc_net_gethostby[addr/name] into the
2451 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2452 routines. Added silc_net_is_ip[4/6]. Affected file is
2453 lib/silcutil/unix/silcunixnet.c. All routines that take
2454 address as argument now supports both IPv4 and IPv6 addresses.
2456 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2458 * Fixed LIST command reply sending in server. Affected file
2461 * Server now sends the kicker's client ID in the KICK notify
2462 to the kicked client. Affected file silcd/command.c.
2464 * The client library now parses the kickers client ID and
2465 UI displays it. Affected files lib/silcclient/client_notify.c
2466 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2468 * Made all payload parsing function prototypes consistent.
2469 They all take now const unsigned char * and uint32 pair as
2470 the payload data instead of SilcBuffer. Changes all around
2471 the source tree. Other unsigned char* -> const unsigned char*
2472 changes around the tree as well.
2474 * Optimized SFTP client and server packet sending not to
2475 allocate new buffer for each packet but to recycle the
2476 first allocated buffer. Affected files are
2477 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2479 * Optimized the SFTP client to use SilcList instead of
2480 SilcDList for requests, because it is faster. Affected file
2481 is lib/silcsftp/sftp_client.c.
2483 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2484 into lib/silccore/silcid.[ch].
2486 Renamed silcpayload.[ch] into silcargument.[ch].
2488 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * If client entry is deleted with active key agreement
2491 session, abort the session.
2493 The silc_client_abort_key_agreement now calls the completion
2494 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2496 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2499 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Don't use __restrict in older GCC's. Affected file is
2502 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2504 * silc_net_localhost now attempts to reverse lookup the
2505 IP/hostname. Affected file lib/silcutil/silcnet.c.
2507 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2508 command. It can be used to gain founder privileges at
2509 the same time when joining the channel.
2511 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2512 kicker's client ID as well. Updated protocol specs.
2514 Defined that the server must send SILC_COMMAND_IDENTIFY
2515 command reply with error status to client who sent
2516 private message with invalid client ID.
2518 Updated the protocol specification.
2520 * Added silc_server_send_command_reply to send any
2521 command reply. Affected file silcd/packet_send.[ch].
2523 * Added silc_id_payload_encode_data to encode ID payload
2524 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2526 * The server now send IDENTIFY command reply with error
2527 status if client ID in private message is invalid. Affected
2528 file silcd/packet_receive.c.
2530 * Save the server key file with server's IP address in
2531 the filename instead of hostname. The affected file is
2532 irssi/src/silc/core/client_ops.c.
2534 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2539 * Added libtool support for compiling shared objects in
2540 lib/silcsim. Affected file configure.in.pre and
2541 lib/silcsim/Makefile.am. Original patch by cras.
2543 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Pid file configuration, and server's config file fixes
2546 patch by toma. Updated CREDITS file.
2548 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Fixed silc_client_channel_message to not try to decrypt
2551 the message twice if it resolved the destination client
2552 information. This could cause of dropping one channel
2553 message. Affected file lib/silcclient/client_channel.c.
2555 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2558 lib/silcclient/client.c. This function is used when the SILC
2559 Client is run under some other scheduler, or event loop or
2560 main loop. On GUI applications, for example this may be
2561 desired to used to run the client under the GUI application's
2562 main loop. Typically the GUI application would register an
2563 idle task that calls this function multiple times in a second
2564 to quickly process the SILC specific data.
2566 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2568 * Fixed silc_server_drop() for dropping the supplementary
2569 groups as well, this could cause a security hole on some
2572 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2577 * Write PID file after dropping privileges. Added -F option
2578 to run server on foreground. A patch by debolaz.
2579 Affected files silcd/server.c, silcd/silcd.c.
2581 * Fixed MOTD to return the MOTD file server name. Affected
2582 file silcd/command.c.
2584 * Added INFO command reply handling to the Irssi SILC Client.
2585 Affected file irssi/src/silc/core/client_ops.c.
2587 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Fixed the silc_idcache_list_* routines to really support
2590 the dynamic list. Fixes a crash. Affected file is
2591 lib/silccore/silcidcache.c.
2593 * Fixed the LIST command reply to really call LIST command's
2594 pending callbacks. Affected file silcd/command_reply.c.
2596 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Update conn->local_entry->nickname after giving NICK
2599 command. Affected file lib/silcclient/command.c.
2601 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2603 * Added the [pid] option to the silcd configuration file
2605 Affected files: serverconfig.[ch] and silcd.c
2607 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Save fingerprint in WHOIS command reply in server.
2610 Affected file silcd/command_reply.c.
2612 * Fixed NICK commands pending callback registration.
2613 Affected file lib/silcclient/command.c.
2615 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Use ++server->cmd_ident when sending commands in server,
2618 instead of random number. Affected file silcd/command.c.
2620 * Fixed GETKEY command reply to call actually GETKEY pending
2621 command callbacks. Affected file silcd/command_reply.c.
2623 * A bit stricter check for nicknames. Check for same nickname
2624 in NICK command also. Affected file silcd/command.c.
2626 * Do not call INFO command everytime client ID changes, only
2627 during first connecting. Affected file lib/silcclient/client.c.
2629 * Set the new nickname only after successful command reply for
2630 NICK command is returned by server. Affected file
2631 lib/silcclient/command.c.
2633 * Remove nicknames from nicklist during server_signoff notify.
2634 Should fix /NAMES bit more. The affected file is
2635 irssi/src/silc/core/silc-channels.c.
2637 * Added `fingerprint' field to the SilcIDListData in the
2638 silcd/idlist.h to hold the fingerprint of the client's
2641 Send the fingerprint of the client's public key in WHOIS
2644 Affected files silcd/command.c, and silcd/idlist.[ch].
2646 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2647 create fingerprint from given data.
2649 * Show the fingerprint of the client's public key in WHOIS.
2650 Affected files irssi/src/module-formats.[ch] and
2651 irssi/src/silc/core/client_ops.c.
2653 * Format the multiple same nicknames also during JOIN and
2654 NICK_CHANGE notifys. Affected file is
2655 lib/silcclient/client_notify.c.
2657 * Do not print error on screen for invalid private message
2658 payload since it can come if someone is sending private
2659 messages with wrong key. Affected file
2660 lib/silccore/silcprivate.c.
2662 * Fixed multiple concurrent /PING crash. Affected file
2663 lib/silcclient/command.c.
2665 * Changed the wrong ID encoding. All IP addresses must be
2666 in MSB first order in encoded format. They were encoded
2667 wrong and was in LSB format. Affected files are
2668 silcd/serverid.c, lib/silcutil/silcutil.c.
2670 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2672 * Call the `connect' client operation through the scheduler
2673 in case of error. Affected file lib/silcclient/client.c.
2675 * Call the `failure' client operation even if the error
2676 occurred locally during a protocol. Affected file is
2677 lib/silcclient/protocol.c.
2679 * Added support of sending LIST command to router from normal
2680 server. This way normal server can get list of all channels
2681 in the network too. Fixed the channel list sending in the
2682 server too. Affected files are silcd/command.c, and
2683 silcd/command_reply.[ch].
2685 * Added silc_server_update_channels_by_server and
2686 silc_server_remove_channels_by_server. They are used during
2687 disconnection of primary router and in backup router protocol.
2688 Affected file silcd/server_util.[ch], silcd/server.c and
2689 silcd/server_backup.c.
2691 * Fixed channel adding to global list in IDENTIFY command
2692 reply in server. Affected file silcd/command_reply.c.
2694 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * If the incoming packet type is REKEY or REKEY_DONE process
2697 that packet always synchronously. Fixes yet another MAC
2698 failed error on slow (dialup) connections. Affected file
2699 lib/silcclient/client.c and silcd/server.c.
2701 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Call check_version SKE callback for initiator too. Affected
2704 file lib/silcske/silcske.c.
2706 * Implemented fix for security hole found in the SKE that was
2707 fixed in the specification few days back; the initiator's
2708 public key is now added to the HASH value computation.
2709 Added backwards support for the old way of doing it too, for
2710 old clients and old servers. Affected file is
2711 lib/silcske/silcske.c.
2713 * Enabled mutual authentication by default in SKE. If initiator
2714 is not providing mutual authentication the responder will
2715 force it. This will provide the proof of posession of the
2716 private key for responder. The affected files are
2717 lib/silcclient/protocol.c and silcd/protocol.c.
2719 * Do not cache anymore the server's public key during SKE.
2720 We do mutual authentication so the proof of posession of
2721 private key is done, and if the server is authenticated in
2722 conn auth protocol with public key we must have the public
2723 key already. Affected file silcd/protocol.c.
2725 * Added new global debug variable: silc_debug_hexdump. If
2726 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2727 file lib/silcutil/silclog.[ch].
2729 * Fixed compilation warning due to char * -> const char *.
2730 Affected files lib/silcutil/silcnet.h, and
2731 lib/silccore/silcauth.[ch].
2733 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Fixed CMODE command when new channel key was created. If
2736 the creation failed the old key was removed. Next time giving
2737 same command would crash the server since the old key was
2738 freed already. Affected file silcd/command.c.
2740 * Fixed the silc_server_announce_get_channels to not crash
2741 on reconnect. Affected file silcd/server.c.
2743 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Added silc_log_set_debug_string function to set a regex
2746 string to match for debug output. Only the function names,
2747 or filenames matching the given debug string is actually
2748 printed. This way it is possible to filter out those debug
2749 strings that user is not interested in.
2751 Fixed a bug in silc_string_regexify.
2753 Affected files lib/silcutil/silclog.[ch], and
2754 lib/silcutil/unix/silcunixutil.c.
2756 * Changed the -d options in both server and Irssi SILC client
2757 to take the debug string as argument. Affected files
2758 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2760 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Added silc_hash_babbleprint to create a Bubble Babble
2763 Encoded fingerprint. The encoding is developed by Antti
2764 Huima (draft-huima-babble-01.txt), and it creates human
2765 readable strings out of binary data. Affected file
2766 lib/silccrypt/silchash.[ch].
2768 * Print the babble print now in addition of fingerprint as well
2769 in Irssi SILC client. Affected files are
2770 irssi/src/fe-common/silc/module-formats.[ch],
2771 irssi/src/fe-common/silc/core/client_ops.c.
2773 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Fixed a security problem found in SKE. The initiator's
2776 public key too is now added to the HASH hash value creation
2777 which is signed by the responder to create the SIGN value.
2778 This will prevent anyone in the middle to lie to the responder
2779 about the initiator's public key. If this is done now, the
2780 man in the middle will get caught. Updated the protocol
2783 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Better installation directory handling. Configure module
2786 paths and other paths automatically to example_silc* files
2787 in doc/. A patch by toma.
2789 * Fixed compiler warning from MPI library, and from SILC RNG.
2792 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2793 It can be configured with ./configure. A patch by toma.
2795 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Find correct make to use in prepare-clean. A patch by
2798 toma. Affected file prepare-clean.
2800 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2802 * Added irssi variables use_auto_addr, auto_bind_ip,
2803 auto_bind_port and auto_public_ip.
2805 * Changed the interface for silc_client_send_key_agreement
2806 in lib/silcclient/silcapi.h
2810 irssi/src/silc/core/silc-core.c
2812 lib/silcclient/silcapi.h
2813 irssi/src/silc/core/silc-channels.c
2814 lib/silcclient/client_keyagr.c
2817 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Added silc_pkcs_public_key_compare to compare two
2820 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2822 * Check that the client who set the founder mode on the
2823 channel is the same client that is giving the founder
2824 mode to itself. It is done by comparing the saved public
2825 key (it is saved even in the authentication is passphrase).
2826 Affected file silcd/command.c.
2828 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2830 * Do not process packet for disconnected socket connection.
2831 Affected file lib/silccore/silcpacket.c.
2833 * Process the DISCONNECT packet through scheduler in the
2834 client library. Affected file lib/silcclient/client.c.
2836 * Fixed the silc_client_packet_parse to not to increase
2837 the packet sequence number if the conn->sock and the
2838 current socket connection is not same. This can happen
2839 for example during key agreement when the conn includes
2840 multiple socket connections (listeners). Affected file
2841 lib/silcclient/client.c.
2843 * The sender of the file transfer request now provides also
2844 the pointer (listener) for the key exchange protocol. If
2845 the listener cannot be created then it sends empty key
2846 agreement and lets the receiver provide the listener.
2848 Added `local_ip' and `local_port' arguments to the
2849 silc_client_file_send. If they are provided they are used,
2850 if not then it will attempt to find local IP address, if
2851 not found or bind fails then the remote client will provide
2854 Affected files are lib/silcclient/client_ftp.c and
2855 lib/silcclient/silcapi.h.
2857 * Extended the FILE SEND command to support defining the
2858 local IP and port for key exchange listener. They are
2859 optional. Affected file irssi/src/silc/core/silc-servers.c.
2861 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Defined to WHOIS command reply the sending of fingerprint
2864 of the client's public key (if the proof of posession of the
2865 corresponding private key is verified by the server).
2866 Updated to the protocol specification.
2868 * Added support of receiving the client's public key's
2869 fingerprint in command reply in client library. Affected
2870 file is lib/silcclient/command_reply.c, and
2871 lib/silcclient/idlist.[ch].
2873 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Do not send over 128 chars long nickname to the server
2876 in NICK command. Affected file lib/silcclient/command.c.
2878 * Do not send over 256 chars long channel names to the server
2879 in JOIN command. Affected file lib/silcclient/command.c.
2881 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Assure that silc_server_close_connection cannot be called
2884 twice for same socket context. Affected file is
2887 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Send error message to application if opening file for
2890 writing during file transfer fails. Affected file is
2891 lib/silcclient/client_ftp.c.
2893 Remove all file transfer sessions for a client that we're
2894 removing from ID cache.
2896 Affected file is lib/silcclient/client_ftp.c.
2898 * Fixed silc_net_addr2bin to return correct address. Affected
2899 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2901 * Fixed file transfer session removing on signoff notify.
2902 Affected file irssi/src/silc/core/silc-servers.c.
2904 * Added the SilcClientFileError to be returned in the monitor
2905 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2906 Affected file lib/silcclient/silcapi.h.
2908 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Fixed a crash in silc_client_ftp_free_sessions and
2911 silc_client_ftp_session_free_client. Affected file
2912 lib/silcclient/client_ftp.c.
2914 * Added `disabled' field in the SilcChannelEntry in the server
2915 to indicate if the server entry is disabled. Affected file
2916 silcd/idlist.h, silcd/command[_reply].c.

2925 * Fixed a crash in client resolving in client_prvmsg.c in
2926 client library. Affected file lib/silcclient/client_prvmsg.c.
2928 * Do not actually remove the client directly from ID cache
2929 during SERVER_SIGNOFF, but invalidate it. This way we
2930 preserve the WHOWAS info for the client. Affected file
2931 silcd/server_util.c.
2933 * Fixed SERVER_SIGNOFF notify handling in the server. The
2934 server is now able to process incoming SERVER_SIGNOFF notify
2935 for a server that it doesn't even know about. It will remove
2936 the clients provided in the notify. Affected file
2937 silcd/packet_receive.c.
2939 * Check for partial packet in data queue after every packet that
2940 was found from the queue. Return and wait for more data if
2941 there is partial data in queue. Affected file is
2942 lib/silccore/silcpacket.c.
2944 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2949 Affected files lib/silcclient/silcapi.h and
2950 lib/silcclient/client_ftp.c.
2952 * Check that newsize in silc_buffer_realloc is larger than
2953 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2955 * Added better monitor of file transfers. It now monitors
2956 key agreement protocol during the file transfer too. Added
2957 error reporting too. Affected files
2958 irssi/src/silc/core/silc-servers.c,
2959 irssi/src/fe-common/silc/module-formats.[ch].
2961 * Wrote a help file for FILE command.
2963 * Added silc_rng_global_get_byte_fast to get not-so-secure
2964 random data as fast as possible. Random data is read from
2965 /dev/urandom if available and from the SILC RNG if not
2966 available. It is used in padding generation. Affected file
2967 lib/silccrypt/silcrng.[ch].
2969 * All packets in client library are now processed synchronously.
2970 Optimized packet processing a lot. Affected file
2971 lib/silcclient/client.c.
2973 * All server connection packets are processing synchronously
2974 now in server, to optimize packet processing. Affected file
2977 * Include files are installed now only in Toolkit distribution
2978 if make install is given. Affected files: all Makefile.am's.
2980 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Assure that silc_client_notify_by_server_resolve does not
2983 resolve the client information multiple times. If it cannot
2984 be found by the first it cannot be found at all. Affected
2985 file lib/silcclient/client_notify.c.
2987 * Fixed WHOWAS command reply calling. Affected file
2988 lib/silcclient/command_reply.c.
2990 * Removed all references to silc_idlist_get_client from the
2991 Irssi SILC client since that call is internal call used by
2992 the library. The Irssi SILC client will use now client
2993 retrieval functions found in silcapi.h.
2995 * Fixed a bug in resolving nickname info before sending
2996 private message. It used freed memory. Affected file
2997 irssi/src/silc/core/silc-servers.c.
2999 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Assure my_channels statistics cannot go negative in server.
3002 Affected files silcd/server.c, silcd/server_util.c.
3004 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3018 * Added silc_net_localip to return local host's IP address.
3019 Affected file lib/silcutil/silcnet.[ch].
3021 * If key exchange or rekey protocol is active for a connection
3022 parse all packets syncronously since there might be packets
3023 in packet queue that we are not able to process without first
3024 processing packets before them. Affected file silcd/server,
3025 lib/silcclient/client.c.
3027 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3028 whether library should continue processing the packet.
3029 Affected file lib/silccore/silcpacket.h.
3031 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3060 lib/silcutil/silcutil.[ch].
3062 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3064 * Resolve the client info when received private message or
3065 channel message for a client which nickname we don't know.
3066 Affected files lib/silcclient/client_prvmsg.c and

3075 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3076 is incomplete and is being resolved, it won't be resolved
3079 Make sure also that USERS command reply does not resolve
3080 twice information. Affected file is
3081 lib/silcclient/command_reply.c.
3083 Make sure that silc_client_get_clients_by_list does not
3084 resolve twice same information.
3086 * Check for valid client->id in the silc_server_free_client_data.
3087 Affected file silcd/server.c.
3089 * Fixed /GETKEY nick@server not to crash if the server entry
3090 is not found. Affected file lib/silcclient/command.c.
3092 * Fixed the silc_server_check_cmode_rights to check the

3098 Affected file silcd/command.c.
3100 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Call the silc_server_udpate_servers_by_server in the
3103 primary router that comes back online in the backup resuming
3104 protocol. Otherwise it routes packets wrong. Affected file
3105 silcd/server_util.[ch], silcd/server_backup.c.
3107 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3110 lib/silcutil/silcbuffmt.[ch].
3112 * Redefined the SILC packet header to include the padding
3113 length. Affected file lib/silccore/silcpacket.[ch].
3115 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3116 length for maximum padding up to 128 bytes). Affected
3117 file lib/silccore/silcpacket.h.
3119 * Removed all backwards support for old 0.5.x MAC thingies.
3120 The SILC packet header change makes it impossible to be
3121 backwards compatible.
3123 * Send the ENDING packet with timeout in the backup resuming
3124 protocol. This is to assure that all routers has connected
3125 to the primary router. Affected file silcd/server_backup.c.
3127 * Changed the RNG to take the first IV from random data. It
3128 used to take it from zero actually. Changed the RNG also
3129 to use /dev/urandom during session. /dev/random is used
3130 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3132 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Changed the SILC packet header to have the first two bytes
3135 (the packet length) encrypted. Affected files aroung the
3136 code tree, lib/silccore/silcpacket.[ch]. Removed the
3137 SilcPacketCheckDecrypt callback. It is not needed anymore
3138 since the silc_packet_receive_process will determine now
3139 whether the packet is normal or special.
3141 * Implemented the unidirectional MAC keys. Affected files
3142 lib/silcske/silcske.c, silcd/protocol.c and
3143 lib/silcclient/protocol.c.
3145 * Implemented the packet sequence number to the MAC computation.
3146 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3147 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3148 lib/silcclient/protocol.c.
3150 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3152 * Allow backup router to announce servers. All servers
3153 announced by backup router are added to the global list
3154 automatically. Update hte server's socket to our primary
3155 router also when backup router announces a server.
3156 Affected file silcd/packet_receive.c.
3158 * Do not update the client->router in the function
3159 silc_server_udpate_clients_by_server if the client is on
3160 global list. We might fail to find any specific server
3161 for locally connected clients and local cell clients. They
3162 should still use the `from' and not `to' as client->router.
3163 This fixes backup router resuming protocol. Affected file
3164 silcd/server_util.c.
3166 * Decrease channel statistics count only if the channel
3167 deletion worked. Affected files are silcd/server.c and
3168 silcd/server_util.c.
3170 * Added silc_server_update_servers_by_server to update origin
3171 of all server entries. Used during backup router protocol.
3172 Affected files silcd/server_util.[ch], silcd/server.c. and
3173 silcd/backup_router.c.
3175 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3176 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3177 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3178 lib/silccrypt/silchmac.c.
3180 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Assure that router cannot reroute the same channel message
3183 to the sender. Affected file silcd/packet_receive.c.
3185 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Made better checks that the channel message is not sent
3188 to the router it came from. Affected file is
3189 silcd/packet_send.c. Fixed memory leak too.
3191 * Announce informations for incoming router connection, but
3192 only after checking if it is replaced by backup router.
3193 Affected file silcd/packet_receive.c.
3195 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Fixed the backup resuming protocol to work in multiple
3198 router environment. Affected file silcd/server_backup.c.
3200 * Route packet only to one router in the function
3201 silc_server_packet_send_to_channel. Affected file is
3202 silcd/packet_send.c.
3204 * Fixed silc_server_send_notify_dest to set the broadcast
3205 flag. Fixed the silc_server_send_notify_topic to actually
3206 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3207 Affected file silcd/packet_send.c.
3209 * Changed the SFTP Filesystem interface. Changed the
3210 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3211 the filesystem operation function. The SilcSFTPFilesystem
3212 is now a context that is allocated by all filesystem allocation
3213 functions and it already includes the operations structure
3214 and filesystem specific context. It is given as argument
3215 now to the silc_sftp_server_start. This made the interface
3216 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3217 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3219 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3221 * Changed the backup router adding and getting interfaces
3222 in the server. The router that will be replaced by the
3223 specified backup router is now sent as argument. Affected
3224 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3227 * Added silc_net_addr2bin_ne to return the binary form of
3228 the IP address in network byte order. Affected files
3229 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3231 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Check for existing server ID in silc_server_new_server
3234 and in silc_server_connect_to_router_final and remove the
3235 old entry if it exists. Affected file silcd/packet_receive.c,
3238 * Send the channel message always to only one router, either
3239 in upstream or downstream. Affected file is
3240 silcd/packet_send.c.
3242 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Wrote the definition of the backup resuming protocol to the
3245 protocol specification.
3247 * Removed one redundant channel key generation from normal
3248 server during joining procedure. Removed one redundant
3249 channel key sending from server to router during joining
3250 procedure. Affected file silcd/command.c.
3252 * Made minor bugfixes to the backup router resuming protocol.
3253 Affected file silcd/server_backup.c, server.c.
3255 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Added --disable-asm configuration option. Affected files
3258 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3261 * Implemented the backup resuming protocol that is used to
3262 resume the primary router position in the cell after the
3263 primary router comes back online. Affected files
3264 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3265 and silcd/server_util.[ch].
3267 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Sleep two (2) seconds after sending QUIT command to server.
3270 Affected file lib/silcclient/command.c.
3272 * Assure that if outgoing data buffer is pending do not force
3273 send any data. Affected file silcd/packet_send.c.
3275 * Assure that if outgoing data buffer is pending do not force
3276 send any data. Affected file lib/silcclient/client.c.
3278 * Implemented the backup router support when the primary router
3279 goes down. The servers and routers can now use the backup
3280 router as new primary router without loosing connectivity.
3282 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3285 in the server to indicate disabled entry. All data read
3286 from the connection will be ignored and no data is sent
3287 for entry that is disabled. Affected files are
3288 silcd/idlist.h, silcd/server.c.
3290 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3292 * Created SFTP client and server test programs in the
3293 lib/silcsftp/tests directory.
3295 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Implemented memory filesystem (virtual filesystem) for
3298 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3301 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Implemented the SFTP (SSH File Transfer Protocol) to the
3304 lib/silcsftp. It includes SFTP client and SFTP server
3307 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3309 * Moved lib/silccore/silcprotocol.[ch] to the
3310 lib/silcutil library.
3312 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3313 take variable argument list pointer as argument. Affected
3314 file lib/silcutil/silcbuffmt.[ch].
3316 * Added silc_buffer_set function that is used to set data
3317 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3318 Affected file lib/silcutil/silcbuffer.h.
3320 * Changed various routines in the core library to use the new
3321 silc_buffer_set instead of allocating new buffer only for
3324 * Added 64-bit value formatting and unformatting support to the
3325 silc_buffer_[un]format routines. Affected file is
3326 lib/silcutil/silcbuffmt.[ch].
3328 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3329 to includes/bitmove.h.
3331 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Fixed channel user mode saving in client library. Affected
3334 file lib/silcclient/command[_reply].c.
3336 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Defined the file transfer to the SILC Protocol. Added
3339 new packet type SILC_PACKET_FTP and defined File Transfer
3340 Payload. The mandatory file transfer protocol is SFTP
3341 (SSH File Transfer Protocol). Affected file in addition
3342 of the internet draft is lib/silccore/silcpacket.h.
3344 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3345 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3346 is used as part of backup router protocol when the primary
3347 router of the cell is back online and wishes to resume
3348 the position as primary router.
3350 * Redefined the MAC generation keys in the protocol. The
3351 same key is not used anymore in both direction. Both
3352 direction will now use different keys for sending and
3353 receiving. This fixes a potential security flaw. This
3354 change causes incompatibilities in the protocol.
3356 * Redefined also the MAC computation from the packet.
3357 An packet sequence number is now added to the MAC
3358 computation. This prevents possible replay attacks against
3359 the protocol. This change too causes incompatibilities
3362 Added `sequence' field to the SilcPacketContext to hold
3363 the current sequence number for the packet.
3365 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Added `created' field to the SilcIDListData in the file
3368 silcd/idlist.h to indicate the time when the entry was
3371 * Added `created' field to the SilcChannelEntry too. Affected
3372 file silcd/idlist.h.
3374 * Added `creation_time' aguments to all the announcement functions
3375 in the server. If it is provided then only the entries that
3376 was created after the provided time frame are actually
3377 announced. Affected file silcd/server.[ch].
3379 * The protocol says that the Channel ID's IP address must be
3380 based on the router's IP address. Added check for this in
3381 the silc_server_new_channel when processing incoming New Channel
3382 Payload. Affected file silcd/packet_receive.c.
3384 * Print out the correct version with --version in SILC client.
3385 Affected file irssi/src/silc/core/silc-core.c.
3387 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Fixed WHOWAS command to check for completnes of the client
3390 entry always, not just when the command is coming from client.
3391 Affected file silcd/command.c.
3393 * Added new function silc_server_packet_queue_purge to purge the
3394 outgoing data queue to the network. After the function returns
3395 it is guaranteed that the outgoing packet queue is empty.
3396 Affected file silcd/packet_send.[ch].
3398 * Purge the outgoing packet queue in the rekey protocol's final
3399 callback to assure that all rekey packets go to the network
3400 before quitting the protocol. Affected file silcd/server.c.
3402 * Added silc_client_packet_queue_parse as similar function as
3403 in server to the client library. The affected file is
3404 lib/silcclient/client.c.
3406 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Splitted silcd/server.c and created silcd/server_util.[ch]
3409 for utility functions.
3411 * Added new socket flag SILC_SF_DISABLED to indicate that the
3412 connection is open but nothing can be sent to or received from
3413 the connection. Affected file lib/silcutil/silsockconn.[ch].
3414 The checking for disabled socket is checked in the low level
3415 silc_socket_write and silc_socket_read functions.
3417 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Allow only nicknames and channel names that fits into the
3420 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3422 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * When processing JOIN command reply in server check that if
3425 the channel exists in our global list we'll move it the local
3426 list. Affected file silcd/command_reply.c.
3428 * Fixed the check whether client is joined on the channel already
3429 in JOIN command. Affected file lib/silcclient/command.c.
3431 * Fixed the JOIN command reply to check whether the channel
3432 already exists. Affected file lib/silcclient/command_reply.c.
3434 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Added silc_ske_status_string to map the SKE error numbers
3437 to readable strings. The affected files are
3438 lib/silcske/silcske[_status].[ch].
3440 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Do not show the private channels on the WHOIS channel list
3443 as it is not allowed by the protocol. The affected file is
3446 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Assure that the packet length digged from the actual packet
3449 is something sensible in the silc_packet_decrypt_rest_special
3450 in lib/silccrypt/silcpacket.c.
3452 * Free and NULL the allocated pointer in silc_hmac_alloc if
3453 the HMAC allocation fails. The affected file is
3454 lib/silccrypt/silchmac.c.
3456 * Print the selected security properties to the log files in
3457 the server. Affected file silcd/protocol.c.
3459 * Add SKE's reference counter even if calling the completion
3460 callback manually. Otherwise it goes negative, although it
3461 does not cause any problems. The affected file is
3462 lib/silcske/silcske.c.
3464 * Remove the client entry with short timeout after giving the
3465 KILL command. Affected file lib/silcclient/command.c.
3467 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3468 case all found clients are already disconnected (WHOWAS would
3469 found them) in the server. Affected file silcd/command.c.
3471 * Update the last_receive (time of last data received) to be
3472 updated only when received private or channel message so that
3473 the idle time showed in WHOIS makes more sense.
3475 * Added boolean field `valid' in to the SilcClientEntry in the
3476 client library to indicate whether the entry is valid or not.
3477 This fixes the nickname change bug on channel when changing
3478 the nickname to be same than the old (like nick to Nick) the
3479 nickname formatter doesn't set the new nick anymore to Nick@host.
3480 Affected file lib/silcclient/idlist.[ch].
3482 * Now actually fixed the nickname changing on disconnection.
3483 Added new function silc_change_nick to the Irssi SILC Client.
3484 Affected file irssi/src/silc/core/client_ops.c,
3485 irssi/src/silc/core/silc-nicklist.[ch].
3487 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3489 * Check that the public key exists in the GETKEY command before
3490 trying to encode it. Affected file silcd/command.c.
3492 * Print some notifications on received public keys with GETKEY
3493 command in the Irssi SILC Client. Affected files are
3494 irssi/src/fe-common/silc/module-formats.[ch],
3495 irssi/src/silc/core/client_ops.c.
3497 * Use IDENTIFY command to resolve the server information in the
3498 GETKEY command instead of INFO command. Affected file
3499 lib/silcclient/command.c.
3501 * All command reply functions in the client library now calls
3502 the pending command reply callbacks even if an error has
3503 occurred. The server has done this a long time and now it was
3504 time to move the client library to this as well. Now all
3505 errors can be delivered back to the pending command reply
3506 callbacks if necessary. Affected files are
3507 lib/silcclient/command[_reply].[ch].
3509 * Change the nickname on disconnection back to the username
3510 because in reconnect the server will enforce it to it anyway.
3511 Affected file irssi/src/silc/core/silc-servers.c.
3513 * Fixed a config file parsing bug in the Irssi SILC client.
3514 Affected file irssi/src/silc/core/clientconfig.c.
3516 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * When printing the channel mode on JOIN, verify that the
3519 channel key and channel's HMAC are valid. Affected file
3520 irssi/src/silc/core/client_ops.c.
3522 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3525 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3526 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3528 * Removed channel key rekey task deleting from the function
3529 silc_server_save_channel_key. Affected file silcd/server.c.
3530 Added explicit timeout task context instead that is used to
3531 delete the task if we are registering a new task before the
3532 new task has elapsed.
3534 * When channel key rekey occurs the client library now saves
3535 the old channel key for a short period of time (10 seconds) and
3536 is able to use it in case some is still sending channel
3537 messages encrypted with the old key after the rekey. Affected
3538 file lib/silcclient/[idlist.h|client_channel.c].
3540 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3542 * Added check to the silc_server_new_id_real to not accept
3543 new ID if it is the sender's own ID. Affected file is
3544 silcd/packet_receive.c.
3546 * Assure that we do not announce ourself or the one we've
3547 sending our announcements when we're router and are announcing
3548 servers to our primary router. Affected file silcd/server.c.
3550 * Fixed silc_server_command_identify_check_client to assemble
3551 correct WHOIS packet. It send corrupted WHOIS packet and
3552 caused problem with router to router connections. Affected
3553 file silcd/command.c.
3555 Fixed also silc_server_command_whois_check the same way
3556 as for the IDENTIFY command.
3558 * Added new SilcIDListStatus to the server in the SilcIDListData
3559 structure. The status now includes the current status of
3560 the entry (like registered, resolved etc.). Affected file
3561 silcd/idlist.[ch]. Defined a bunch of different status types
3562 as well. This replaced the old boolean registered field as well.
3564 Added resolve_cmd_ident field to the SilcClientEntry structure
3565 too so that if the entry is for example being resolved so
3566 another command may attach to the same pending command reply
3567 without requiring to resolve the same entry again. This concept
3568 should optimize the WHOIS and the IDENTIFY resolving under
3569 heavy load by taking away unnecessary resolving for entries
3570 that are being resolved already.
3572 Added support for adding multiple pending commands for one
3573 command idenfier. Affected file silcd/command[_reply].[ch].
3575 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3576 before deleting the data. Otherwise the hash table will have
3577 freed data in comparison functions. Affected file is
3578 silcd/command_reply.c.
3580 * Fixed silc_idlist_replace_client_id to add the new entry to
3581 the cache with NULL nickname. Otherwise there will be invalid
3582 memory as the nickname after the nickname is freed. Affected
3583 file silcd/packet_receive.c.
3585 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3586 saved into wrong slots because the previous number of entries
3587 was not taken into account. Affected file silcd/idlist.c.
3588 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3590 * If we are router and we receive JOIN notify to a channel that
3591 does not have any users then notified client is marked as the
3592 channel founder, as it is it. The affected file is
3593 silcd/packet_receive.c
3595 * Added to the extended hash table API's table_del_*ext functions
3596 the destructor as argument too, so that the caller can decide
3597 which destructor to use or whether to use destructor at all.
3598 Affected file lib/silcutil/silchashtable.[ch].
3600 * Fixed ID Cache purging. It actually deleted the entries from
3601 the hash table after the data was freed. The hash table ended
3602 up comparing freed memory. The affected file is
3603 lib/silccore/silcidcache.c.
3605 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Fixed Irssi SILC client's KILL command's HELP syntax.
3609 * The USERS command now resolves the detailed user information
3610 if the userinfo field is missing. Affected file is
3611 lib/silcclient/command_reply.c.
3613 * Do not print error in silc_file_read if the read file does
3614 not exist. Just silently return NULL. Affected file is
3615 lib/silcutil/silcutil.c.
3617 * Fixed the silc_log_output to not wine about NULL filename
3618 and to not create some bogus " " filename. Affected file is
3619 lib/silcutil/silclog.c.
3621 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Fixed various printing bugs on the user interface in the
3624 Irssi SILC Client. Minor changes that were forgotten from
3627 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed the configure.in.pre and the compilation and distribution
3630 environment to support the new autoconf 2.52. That version is
3631 now required to compile the CVS trunk.
3633 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3636 to generally parse user@fqdn format strings. Affected file
3637 lib/silcutil/silcutil.c.
3639 * Added nickname_format and nickname_force_format fields to the
3640 SilcClientParams structure. The first one defines the format
3641 for the nicknames that the library will enforce if the receives
3642 multiple same nicknames. The second one is boolean value and
3643 can be used to force the library to always enforce the format
3644 to the nicknames regardles whether there are multiple nicknames
3645 or not. This configurable formatting was employed to flexibly
3646 support accessing multiple nicknames from the user interface.
3647 The userinterface can now set the nicknames to what ever format
3648 they prefer. Affected file lib/silcclient/silcapi.h.
3650 Added function silc_client_nickname_format to the file
3651 lib/silcclient/idlist.c. It performs the nickname formatting.
3653 Added new field `hostname´ to the SilcClientEntry context.
3654 It holds the hostname of the client. Affected file is
3655 lib/silcclient/idlist.h.
3657 * Irssi SILC Client sets the nicknames in nick@hostn format.
3658 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3659 irssi/src/silc/core/silc-core.c.
3661 The WHOIS printing now also shows both the real nickname and
3662 the formatted nickname so that user knows how to access the
3663 user if there are multiple same nicknames cached. Affected
3664 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3665 printing formatting too to take the hostname now as a separate
3666 argument. The Affected file is
3667 irssi/src/fe-common/silc/modules-formats.[ch].
3669 * Changed the silc_client_get_clients_local to accept the formatted
3670 nickname as argument. It accepts the real nickname too but the
3671 formatted nickname can be used to find the true entry from
3672 multiple entries. Affected file lib/silcclient/silcapi.h and
3673 lib/silcclient/idlist.c.
3675 * Added nickname_format_parse field to the SilcClientParams.
3676 It is a callback function provided by the application to parse
3677 the nickname out of the formatted nickname string. The library
3678 calls it to get the nickname from the formatted string. Since
3679 the application generally knows better the format of the nickname
3680 string it parses it instead of the library, even though library
3681 encodes the formatted string. If the callback function is not
3682 provided then the library will use the string as is. The
3683 affected file is lib/silcclient/silcapi.h.
3685 * All the nickname strings passed to the client library in
3686 commands are now expected to be formatted nickname strings.
3687 If the command does not support the formatted nickname string
3688 it will assume that the sent string is the actual nickname.
3689 Affected file lib/silcclient/command.c.
3691 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Added public key authentication support to OPER and SILCOPER
3694 commands in the client library. Affected file is
3695 lib/silcclient/command.c.
3697 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3699 * Changed the get_auth_methdod client operation to be asynchronous.
3700 It can be async if the application resolves the authentication
3701 method from the server during the negotiation. Added new
3702 SilcGetAuthMeth completion callback that the application will
3703 call after resolving the authentication method.
3705 Added function silc_client_request_authentication_method that
3706 the application can use to resolve the authentication method
3707 from the server. Added also SilcConnectionAuthRequest callback
3708 that the library will call after the server has replied. The
3709 application can call this function if it does not know the
3710 current authentication method.
3712 Affected files are lib/silcclient/client.c and
3713 lib/silcclient/silcapi.h.
3715 * The Irssi SILC client now automatically resolves the authentication
3716 method incase any configuration information is not present (and
3717 currently there never is). The affected file is
3718 irssi/src/silc/core/client_ops.c.
3720 * Fixed public key authentication from the client library.
3721 Affected file lib/silcclient/protocol.c. Changed also the
3722 protocol specification about the public key authentication in
3723 the connection authentication protocol. The actual data to be
3724 signed is now computed with a hash function before signing.
3726 * Fixed the public key authentication from the server as well.
3727 Affected file silcd/protocol.c.
3729 * Removed the mlock()'s from the memory allocation routines.
3730 Affected file lib/silcutil/silcmemory.c. The ./configure does
3731 not check anymore for the mlock(). Affected file is
3734 * Fixed USERS command in server to allow the execution of the
3735 command for private and secret channels if the client sending
3736 the command is on the channel. Affected file silcd/command.c.
3738 * Fixed silc_client_get_clients_local to return the clients
3739 count correctly. It could return wrong value. Affected file
3740 lib/silcclient/idlist.c.
3742 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3744 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3745 types. The assembler optimizations seemed not to like 64-bit
3746 data types. The assmebler optimizations thus are now enabled
3747 also for BSD systems as opposed to only enable them for Linux.
3749 * Do not check for threads at all on BSD systems. Affected
3750 file configure.in.pre.
3752 * Removed -n and -h options from the Irssi SILC Client since
3753 they are not used in silc.
3755 * Fixed the prime generation to assure that the first digit
3756 of the generated random number is not zero since our conversion
3757 routines does not like number strings that starts with zero
3758 digit. If zero digit is seen the random number is regenerated.
3759 This caused some corrupted RSA keys when the zero first digit
3760 was met. Affected file lib/silcmath/silcprimegen.c.
3762 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Fixed WIN32 configuration in the ./configure script.
3765 Fixed to include xti.h on environments that has it.
3766 Patches by Carsten Ilchmann and andrew.
3768 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Changed the silc_id_create_client_id to be collision
3771 resistant. It is now assured that there cannot be created
3772 two same client ID's. I suspect that some weird bugs in
3773 the server were actually caused by duplicate Client IDs.
3774 Affected file silcd/serverid.[ch]. A router receiving
3775 new ID now also assures and informs the sending server
3776 if the ID caused collision.
3778 * Changed the silc_id_create_channel_id to also assure that
3779 there are no collisions.
3781 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Statement about ignoring the Mutual Authentication flag when
3784 performing rekey with PFS was a bit misleading. It is ignored
3785 if it was set in the initial negotiation, it cannot be even
3786 set in the rekey. Fixed in the ke-auth draft. Started the
3787 new versions of the protocol drafts in the doc/.
3789 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3791 * Fixed a bug in silc_client_command_identify_save when saving
3792 new channel information. The channel name was no duplicated
3793 and caused crash on exit. Affected file is
3794 lib/silcclient/command_reply.c.
3796 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3798 * Fixed the getkey command handling in the server. Send just
3799 empty OK reply to the sender if the key could not be fetched
3800 (but everything else was ok, like the key just was not available).
3801 Changed the public key parameter to optional in the protocol
3802 specs so that empty OK reply can be sent. Affected file
3805 Added a message to Irssi SILC client to tell to user if the
3806 server did not return a public key.
3808 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Fixed a channel key regeneration bug. It registered new
3811 timeout tasks exponentially until all system resources were
3812 used. Affected file silcd/server.c.
3814 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * Added the SILC Document generator to the scripts/silcdoc.
3817 It can be used to generate the Toolkit Reference Manual out
3818 of the source tree. Internally it will also use the RoboDoc
3819 generator now imported in util/robodoc.
3821 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Added couple of return's in rekey protocol if error orccurred
3824 during the protocol. The execution must be terminated.
3825 Affected file silcd/protocol.c. Also, terminate the protocol
3826 always with timeout.
3828 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * The client's Client ID was created initally from the wrong
3831 nickname (it could have been in format nick@host) in the
3832 silc_server_new_client. Affected file silcd/packet_receive.c
3834 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3836 * Added some SILC_LOG_ERROR's to various error conditions
3837 if client could not be added to ID cache. Affected files
3838 silcd/packet_receive.c and silcd/server.c.
3840 * When client's sock->user_data is freed, NULL also the
3841 client->router and client->connection pointers. Added check
3842 for these pointers being NULL to various places around the
3843 code. Affected file silcd/server.c.
3845 * Added client->data.registered == TRUE checks to various
3846 places around the code to assure that unregistered client's
3847 are not handled when it is not allowed. Affected file
3850 * Added `bool registered' fields to all
3851 silc_idlist_[server|client]_get_* routines to indicate whether
3852 the fetched client needs to be registered or not. Affected
3853 file silcd/idlist.[ch].
3855 * Add your own entry as registered to the ID cache in the
3856 server. Affected file server.c.
3858 * Fixed a bug in silc_server_new_server. The SilcServer was
3859 set as the new server's context instead of SilcServerEntry.
3860 This naturally caused some weird bugs.
3862 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Do not delete the channel rekey task when adding it
3865 for in silc_server_create_channel_key.
3867 * Changed the silc_server_create_channel_key to return
3868 TRUE or FALSE to indicate the success of the channel key
3871 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * Fixed MSVC++ project files and added missing files to
3874 Makefiles under win32/.
3876 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3878 * Do not add TCP_NODELAY flag if the operating system
3879 does not have it defined. Affected files are
3880 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3882 * Fixed buffer overflow from Irssi SILC Client. Affected
3883 file irssi/src/fe-common/core/themes.c.
3885 * Fixed double free in client library in the file
3886 lib/silcclient/client.c when disconnecting from server.
3888 * Applied double free patch from cras to Irssi SILC client.
3889 Affected files irssi/src/core/[modules/expandos].c
3891 * Fixed the disconnection handling to Irssi SILC Client.
3892 The application must call silc_client_close_connection
3893 in ops->connect client operation in case of failure of
3894 the connection. Affected file is
3895 irssi/src/silc/core/client_ops.c.
3897 * Do not set sock->protocol to NULL in the function
3898 silc_client_close_connection after executing the protocol's
3899 final callback since the sock might not be valid anymore.
3900 Affected file lib/silcclient/client.c.
3902 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Do not enable SILC_THREADS if the linking with libpthread
3905 did not happen. Affected file configure.in.pre.
3907 * Added notion to protocol specification that server must
3908 verify the sent authentication payload with CMODE when
3909 setting the channel founder key. Implemented it to the
3910 server. Affected file silcd/command.c.
3912 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Added _EXTRA_DIST SILC distribution variable to the
3915 distributions file. It is used to conditionally add extra
3916 files or directories to the specific distribution. Affected
3917 files ./prepare, Makefile.am.pre and distributions.
3919 Removed the `_' from the start of the distribution names.
3922 * Added README.WIN32 for instructions to compile the Toolkit
3925 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Fixed a double free in disconnection in the server. Affected
3928 file is silcd/server.c.
3930 * Fixed the lib/silcske/groups.c to work now also with GMP
3931 MP library. The string conversion did not work when using
3932 specific base and the base is indicated in the string as well.
3934 * Created win32/ directory which now includes MSVC++ specific
3935 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3936 It will appear only in the toolkit distribution
3938 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3940 * Changed the key material distribution function in case when
3941 the hash output is too short. The data is now concatenated
3942 a bit differently than it used to. Made the change to the
3943 SKE protocol specification.
3945 * Added better GMP detection to configure.in.pre. A patch
3948 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Fixed a minor bug in SKE that might cause some problem on
3951 some platforms. Affected file lib/silcske/silcske.c.
3953 * Added the cookie checking for initiator in the SKE. It checks
3954 that the responder returns the sent cookie unmodified. The
3955 affected file is lib/silcske/silcske.c. Added new SKE
3956 error type INVALID_COOKIE that can be sent during the
3957 negotiation. Fixed some memory leaks as well.
3959 * Added the "invalid cookie" error message to Irssi SILC client's
3962 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3964 * Added `task_max' field to the SilcClientParams to indicate
3965 the maximum tasks the scheduler can handle. If set to zero,
3966 default values are used. Affected file lib/silcclient/silcapi.h.
3968 * Fixed memory leaks in silc_client_close_connection. Affected
3969 file lib/silcclient/client.c.
3971 * Added silc_client_del_client_entry to client library to free
3972 all memory of given client entry. Affected file is
3973 lib/silcclient/idlist.[ch].
3975 * Added new functions silc_client_del_channel and
3976 silc_client_del_server to delete channel and server entries.
3977 Affected file lib/silcclient/[silcapi.h/idlist.c].
3979 * Removed silc_client_del_client_by_id from silcapi.h.
3981 * Fixed the INFO command to return the server's own info
3982 correctly when querying by Server ID. Affected file is
3985 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3987 * Removed the non-blocking settings in WIN32 code in the
3988 silc_sock_[read/write] and added SleepEx instead. Affected
3989 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3990 of input data is now checked with FIONREAD and ioctlsocket.
3992 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Call silc_schedule_task_del_by_context in the
3995 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3996 Affected file lib/silccore/silcprotocol.c.
3998 * Call silc_protocol_cancel for active protocols in the
3999 silc_server_close_connection if the funtion
4000 silc_server_free_sock_user_data has not been called.
4001 Affected file silcd/server.c.
4003 * Generic tasks cannot be deleted using the del_by_fd
4004 task deleting function since generic tasks does not match
4005 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4007 * Added a notion to SILCOPER help file that the SILCOPER works
4008 only on router server, not on normal server.
4010 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Added for WIN32 support for the new scheduler as well.
4013 Affected file lib/silcutil/win32/silcwin32schedule.c.
4015 * Fixed the SHA1 implementation to work on various platforms.
4017 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4020 API. It is part of the scheduler now. Everything else is
4021 as previously but some functions has changed their names.
4022 Checkout the lib/silcutil/silcschedule.h for the interface.
4023 Updated all applications to use the new interface. Affected
4024 files are lib/silcutil/silcschedule.[ch].
4026 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Found a bug in the SKE implementation. The HASH value,
4029 specified by the protocol, was not computed correctly. The
4030 public key of the responder was not added to the computation
4031 even though it is mandatory. Affected file lib/silcske/silcske.c.
4032 This unfortunately causes incompatibilities with older
4033 clients and servers.
4035 * Added WIN32 specific network init and uninit functions:
4036 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4037 the Winsock2. Affected file lib/silcutil/silcnet.h and
4038 lib/silcutil/win32/silcwin32net.c.
4040 * Set the socket always to nonblocking mode on WIN32 after
4041 reading data or writing data. Affected file is
4042 lib/silcutil/win32/silcwin32sockconn.c.
4044 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Fixed various compilation problems under WIN32. Affected
4047 files lib/silcutil/win32/silcwin32thread.c and
4048 lib/silcutil/win32/silcwin32schedule.c.
4050 * Removed all _internal.h #includes from public header
4051 files. Internal headers must never be included from
4054 Removed also the lib/silcske/payload_internal.h file.
4056 * All include files that may be needed (public and some others
4057 included by the public headers) by application developers are
4058 now copied to the ./includes directory. It does not copy any
4059 internal headers. Affected file Makefile.defines.pre and all
4060 Makefile.am's under lib/ and subdirs.
4062 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Do not change the ~/.silc directory's permissions automatically.
4065 Affected file irssi/src/silc/core/clientutil.c.
4067 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4069 * Do not cancel the protocol in silc_server_close_connection
4070 it might cause recursion. Now cancelled in the function
4071 silc_server_free_sock_user_data. Affected file silcd/server.c.
4073 * Fixed the silc_server_remove_clients_by_server to regenerate
4074 the channel keys correctly finally. Added also new function
4075 silc_server_remove_clients_channels to actually do it.
4076 Affected file silcd/server.c.
4078 * Fixed the silc_server_new_channel to not crash by giving
4079 wrong router to the new channel. Affected file is
4080 silcd/packet_receive.c.
4082 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4085 which is given as argument to the silc_client_alloc now.
4086 It can be used to configure the client and set various parameters
4087 that affect the function of the client.
4089 * The USERS command in server did not check whether the channel
4090 is private or secret. Affected file silcd/command.c.
4092 * Added new argument to the USERS command in protocol specification.
4093 The USERS command now can take the channel name as argument
4094 as well. Added support for this in client and server and
4095 updated the protocol specs.
4097 * Completed the GETKEY command in client. It can be now used
4098 to fetch also servers public key not only some clients.
4099 Affected files lib/silcclient/command[_reply].c.
4101 * Added silc_client_get_server to return server entry by the
4102 server name. Affected files lib/silcclient/silcapi.h and
4105 * Redefined the IDENTIFY command in protocol specification to be
4106 more generic. It now can be used to query information about
4107 any entity in the SILC Network, including clients, servers and
4108 channels. The query may be based either the entity's name
4109 or the ID. Added support for this in both client and server.
4111 Affected files silcd/command.c and lib/silcclient/command.c
4112 and command_reply.c.
4114 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4115 the _from_client and _from_server functions. Affected file
4118 * Added silc_client_get_channel_by_id_resolve to the file
4119 lib/silcclient/silcapi.h to resolve channel information by
4120 its ID. Added also silc_client_get_channel_by_id that
4121 does not resolve it from the server.
4123 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * Added SilcServerEntry context into the client library
4126 to represent one server. The INFO command now allocates
4127 these to save the resolved server info. For now on the
4128 client library will also keep information about servers,
4129 connected and resolved with INFO.
4131 The INFO command now allocates the SilcServerEntry context
4132 and saves the server info there. The COMMAND_REPLY in
4133 the INFO now returns the parameters to application in
4134 same order as defined in the protocol specification.
4136 The entries are cached in the client->server_cache.
4138 * The INFO command is now issued after received the Client ID
4139 from the server. Affected file lib/silcclient/client.c.
4141 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4142 to the application as the mode changer might be server.
4143 It is guaranteed that NULL is not returned anymore to the
4144 application. Affected file lib/silcclient/client_notify.c.
4146 The ID Type is now also passed to the application so that
4147 it can check whether the returned entry is SilcClientEntry
4150 Added new function silc_client_get_server_by_id to return
4151 the server entry by ID. Affected files are the
4152 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4154 * Do not create the channel in the Irssi SILC Client when issuing
4155 the JOIN command but when received the sucessful JOIN command
4156 reply. Otherwise the channel might get created even though we
4157 could not join it. The Affected file is
4158 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4160 * Fixed a channel joining bug in router. The router must also
4161 check the channel modes, invite and ban lists etc. when serving
4162 the JOIN command sent by normal server. Affected file is
4163 silcd/command.c. The router now resolves the client's
4164 information from the server who sent the JOIN command if it
4165 does not know it, and processes the JOIN command only after
4168 * Changed the SilcCommandCb to take new argument; void *context2.
4169 Affected file lib/silccore/silccommand.h
4171 The second argument in the command callbacks in the server now
4172 includes the SilcServerCommandReplyContext if the command was
4173 called as pending command callback from the command reply.
4174 Otherwise it is NULL. When called as pending the status of the
4175 command reply will be checked and if it was erronous the
4176 error will be sent to the original sender of the command.
4177 This way the client always receives the error messages even
4178 though the server was actually the one who received the error
4179 when it resent the command to router, for example. Affected
4180 files silcd/command[_reply].[ch].
4182 * Fixed sending WHOWAS command's error message to client if
4183 the requested client could not be found. It was missing.
4186 * Changed the CMODE and CUMODE commands reply arguments in the
4187 protocol specification. The Channel ID is now sent in both
4188 of the commands to identify the channel. Implemented this
4189 new feature to the client and server. Affected files
4190 lib/silcclient/command_reply.c and silcd/command.c.
4192 * Made better checks for invite and ban lists in the JOIN
4193 command in server. Affected file silcd/command.c.
4195 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4197 * The server now performs the incoming host IP/DNS lookup
4198 using the silc_socket_host_lookup and thus does not block
4199 the server anymore. Affected file silcd/server.c.
4201 * Completed the multi-thread support for SILC Scheduler in
4202 the lib/silcutil/silcschedule.c.
4204 * Fixed the configure.in.pre to detect the pthread correctly
4207 * Fixed a deadlock in silc_task_queue_wakeup in the file
4208 lib/silcutil/silctask.c.
4210 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4212 * Added new function silc_schedule_wakeup that is used in
4213 multi-threaded environment to wakeup the main thread's
4214 schduler. It needs to be used when a thread adds a new task
4215 or removes a task from task queues. After waking up, the
4216 scheduler will detect the task queue changes. If threads
4217 support is not compiled in this function has no effect.
4218 Implemented the wakeup mechanism to both Unix and WIN32
4219 systems. Affected files are lib/silcutil/silcschedule.[ch],
4220 lib/silcutil/unix/silcunixschedule.c and the
4221 lib/silcutil/win32/silcwin32schedule.c.
4223 * Added new function silc_task_queue_wakeup to wakeup the
4224 scheduler by the specified task queue. Affected file
4225 lib/silcutil/silctask.[ch].
4227 * The silc_socket_host_lookup_start now wakes up the scheduler
4228 after adding the timeout task. Affected file is
4229 lib/silcutil/silcsockconn.c.
4231 * The silc_socket_host_lookup is synchronous now if the threads
4232 support is not compiled in. However, the callback is still
4233 called asyncronously through the scheduler, anyway. Affected
4234 file lib/silcutil/silcsockconn.c.
4236 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4238 * Added new function silc_socket_host_lookup to perform
4239 asynchronous IP and FQDN lookups for the socket connection.
4240 Affected files lib/silcutil/silcsockconn.[ch].
4242 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4244 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4245 that may or may not compile the mutex support in.
4247 Changed the silc_mutex_alloc interface. It allocates the
4248 mutex now to the sent pointer and returns TRUE or FALSE.
4250 Affected file lib/silcutil/silcmutex.h.
4252 * Wrote the SILC Task Queue interface to support multi-threads.
4253 Affected file lib/silcutil/silctask.[ch].
4255 * Wrote the SILC Scheduler to support multi-threads. Affected
4256 file lib/silcutil/silcschedule.c.
4258 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4261 in lib/silcutil/win32/.
4263 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4265 * Defined SILC Mutex API and SILC Thread API and implemented
4266 them for Unix. Affected files are
4267 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4268 lib/silcutil/unix/silcunixmutex.c and
4269 lib/silcutil/unix/silcunixthread.c.
4271 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4273 * Fixed the silc_server_remove_clients_by_server's channel
4274 key re-generation. The hash table handling was incorrect
4275 and would not work with many channels. Affected file is
4278 * Fixed some memory leaks around the server code.
4280 * Rewrote the silc_server_get_users_on_channel to support IPv6
4281 based Client ID's. Affected file silcd/server.c.
4283 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4284 specification. However, a separate document must be written
4285 to define the detailed signing procedure and the payload
4286 associated with the flag. Defined the flag to the
4287 lib/silccore/silcchannel.h as well.
4289 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4291 * Changed the dynamic tables to static size tables in the
4292 lib/silccrypt/silchmac.c.
4294 * Removed GCC dependencies from the code. A patch by cras.
4296 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4298 * Do not show the error "Error receiving packet bla bla"
4299 in server if it really was not an error (-2 means that reading
4300 is pending). Affected file silcd/server.c.
4302 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4304 * Fixed a possible crash in silc_server_remove_clients_by_server
4305 in silcd/server.c. Fixed there also some memory leaks.
4307 * Fixed the silc_idlist_replace_client_id. It could replace
4308 wrong key in the hash table. Affected file silcd/idlist.c.
4310 * Do not check whether there are global users on the channel
4311 if the channel->global_users is FALSE. Affected functions
4312 silc_server_remove_from_one_channel and
4313 silc_server_remove_from_channels in silcd/server.c. Also,
4314 do not check if the removed client is local as we can be
4315 sure that global client was not removed from the channel
4316 and checking for global users is not needed.
4318 * The silc_server_remove_clients_by_server now re-generates
4319 the channel keys correctly for those channels that had
4320 clients removed from them. Affected file silcd/server.c.
4322 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4324 * Found the reason of random crashes in the server. We weren't
4325 ignoring the SIGPIPE signal (which can be sent in write())
4326 and it crashed the server. Affected file silcd/silcd.c.
4328 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4330 * Assure that sock->user_data is not NULL in the function
4331 silc_server_packet_send in silcd/packet_send.c.
4333 * Disconnect the remote connection if it could not be added
4334 to any ID lists in the server. The affected file is
4337 * Check in silc_server_packet_send[_real/dest] that the
4338 socket is not disconnecting and ignore the data if it is.
4339 Affected file silcd/packet_send.c.
4341 * Define inline to __inline on native WIN32 compilation.
4342 Affected file includes/silcwin32.h.
4344 * Added some explicit type casts for inline code since MSVC
4345 require them. Affected files lib/silcutil/silcbuffer.h,
4346 lib/trq/silcdlist.h and lib/trq/silclist.h.
4348 * Print warning in log files from now on if the packet
4349 decryption fails. Affected file silcd/server.c.
4351 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4353 * Changed the `say' client operation's interface to accept
4354 new `type' argument to indicate the type of the message sent
4355 by the library. The application may filter the library's
4356 messages according the type. The affected file is the
4357 lib/silcclient/silcapi.h.
4359 * Added two new functions to lib/silcclient/silcapi.h:
4360 silc_client_del_client and silc_client_del_client_by_id.
4361 Affected file lib/silcclient/idlist.c.
4363 * Moved the clientincludes.h from includes/ to silc/ and
4364 serverincludes.h from includes/ to silcd/.
4366 * The modes for the CMODE and CUMODE are now passed as
4367 uint32 for application with COMMAND_REPLY. The affected
4368 file is lib/silcclient/command_reply.c.
4370 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * /WHOIS without arguments shows client's own information.
4373 Affected file lib/silcclient/command.c.
4375 * Changed PING to not accept any arguments. The specs
4376 says that client can ping only the connected server so
4377 requiring an argument is not needed. Affected file is
4378 lib/silcclient/command.c.
4380 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4382 * Fixed a fatal bug in private message sending and reception
4383 encryption and decryption when using private message keys.
4384 The implementation was incorrect and did not follow the
4385 specification. It causd that some of the message were
4386 lost since it did not use the sending and receiving keys
4387 as the protocol suggests. This has been fixed and will cause
4388 incompatibilities with older clients when sending private
4389 message encrypted with private message keys. Affected files
4390 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4391 and various other in Irssi SILC Client.
4393 Added `responder' boolean argument to the functions
4394 silc_client_add_private_message_key[_ske] to indicate when
4395 the key is added as responder or initiator of the key
4398 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Removed the silc_ske_check_version function and created
4401 a SilcSKECheckVersion callback. Added also a function
4402 silc_ske_set_callbacks that is now used to set all SKE
4403 callbacks. The callback functions are not given to
4404 the SKE functions anymore, but this function is used to
4407 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4409 * Added `silc_version' argument to the silc_client_alloc
4410 to define the version of the application for the library.
4411 The library will use the version string to compare it
4412 against the remote host's (usually a server) version
4413 string. Affected file lib/silcclient/silcapi.h
4415 * Added the KE protocol context to Key Agreement context
4416 in client library so that we can abort the SKE if it
4417 is in process when we get timeout. Affected file is
4418 lib/silcclient/client_keyagr.c.
4420 * Do not resolve the client ID forever if it returns in the
4421 first time that such client does not exist. This was done
4422 for example with private message. Affected file is
4423 lib/silcclient/client_prvmsg.c.
4425 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4427 * Do not add regex.h for WIN32. The affected file
4428 includes/silcincludes.h.
4430 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4431 not work yet 100%. It generates the DLL's automatically
4432 when compiling with --with-win32 under cygwin.
4434 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4436 * lib/contrib/regex.c is not compiled on WIN32.
4438 * Added silc_net_get_socket_opt function to the
4439 lib/silcutil/silcnet.h.
4441 * Added includes/silcwin32.h for WIN32 specific includes
4444 * Do not use ptime structure or any of the posix process
4445 functions on WIN32 in lib/silccrypt/silrng.c.
4447 * Added silc_gettimeofday to provide generic function
4448 for struct timeval on all platforms. Added the function
4449 to lib/silcutil/silcutil.h.
4451 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4453 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4454 library as they clearly belong there. As a plus side we
4455 can make the actual socket connection routines platform
4458 Added also new generic function silc_socket_read and
4459 silc_socket_write (that used to be silc_packet_[read/write].
4460 The implementation of these are platform specific.
4462 * Added WIN32 specific routines of silc_socket_[read/write]
4463 to lib/silcutil/win32/silcwin32sockconn.c.
4465 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4467 * Added preliminary support for native WIN32 compilation under
4468 cygwin (using the -mno-cygwin option for GCC) to the
4469 ./configure.in.pre. The --with-win32 now prepares the
4470 compilation for native WIN32.
4472 * Rewrote the SILC Scheduler interface in the file
4473 lib/silcutil/silcschedule.h. The scheduler is now context
4474 based and does not have anymore any global static scheduler.
4475 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4476 and created lib/silcutil/win32 directory for WIN32 based
4479 * Added Unix specific network routines to the
4480 lib/silcutil/unix/silcunixnet.c and the old
4481 lib/silcutil/silcnet.c includes now only generic routines.
4483 Added WIN32 specific network routines to the
4484 lib/silcutil/win32/silcwin32net.c.
4486 * Added Unix specific utility functions from the
4487 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4489 * Added WIN32 SILC Scheduler to the file
4490 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4493 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4495 * Do not handle JOIN notify in the server if the target client
4496 is not registered (idata->registered == FALSE). The affected
4497 file is silcd/packet_receive.c.
4499 * Update the nickrec->founder in event_cumode in the Irssi SILC
4500 client. Affected file irssi/src/silc/core/silc-channels.c.
4502 * Fixed the CUMODE_CHANGE notify handling in the server when
4503 server and router are announcing their clients on channels.
4504 Now the mode changes are saved and notified correctly. The
4505 affected file is /silcd/packet_receive.c.
4507 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4508 They really did not replace the cache entry in the ID Cache.
4509 Now they do that. Affected file silcd/idlist.c.
4511 * Fixed the KICK notify handling in the Irssi SILC client to
4512 update the channel records so that the kicked client does not
4513 appear to be on the channel. The affected file is
4514 irssi/src/silc/core/silc-channels.c.
4516 * Always update the conn->current_channel when executing command
4517 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4519 * Fixed the KILL notify handling in Irssi SILC client to remove
4520 the killed client on all channels.
4522 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed the silc_parse_command_line to remove extra spaces
4525 from the start and end of the arguments. Affected file is
4526 lib/silcutil/silcutil.c.
4528 * Cancel and free any active protocol in the function
4529 silc_server_close_connection. Affected file silcd/server.c.
4531 * Cancel and free any active protocol in the function
4532 silc_client_close_connction. Affected file is
4533 lib/silcclient/client.c.
4535 * Do not execute the KILL command for clients that are in
4536 history (ie. they are not in the network). Affected file is
4539 * Fixed KILL notify handling, client does not crash anymore.
4540 Affected file irssi/src/silc/core/silc-channels.c.
4542 * Reduced the default packet buffer size from 2048 to 1024 in
4543 lib/silccore/silcpacket.c.
4545 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4546 counter to the SKE context that is incresed when the SKE library
4547 performs async operation outside the library. If the outside
4548 process frees the SKE context and FREED status will be set
4549 and the library will detect after the sync operation that the
4550 libary is freed. The affected files are
4551 lib/silcske/silcske[_status].[ch].
4553 * Resolve the client entry information in the function
4554 silc_client_channel_message to assure that NULL pointer is not
4555 passed as client entry to the application. */
4557 * Fixed the task timeout calculation to assure that there is
4558 never negative timeouts. The affected file is
4559 lib/silcutil/silcschedule.c.
4561 * Fixed the channel user mode notification sending in server.
4562 It was sent point-to-point to the router (or to server by router)
4563 but it needs to be destined to a channel. The routines now
4564 supports sending the channel user mode notifys to the channels
4565 when announcing clients and channels. Affected files are
4566 silcd/server.c and silcd/packet_receive.c.
4568 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4569 It did not actually replace the old channel entry in the cache.
4570 Affected file lib/silcclient/client_notify.c.
4572 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Fixed a possible crash in silc_packet_send_prepare. It now
4575 assures always that there is enough space in the buffer and
4576 at the tail area of the buffer (for MAC).
4578 Fixed the inbound buffer reallocation in silc_packet_read.
4579 It was old code and did not handle the reallocation correctly.
4582 The affected file is lib/silccore/silcpacket.c.
4584 * Fixed buffer overflow in silc_parse_nickname in the file
4585 lib/silcutil/silcutil.c.
4587 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * make install generates new server keys only if there is not
4592 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4595 Added check that if the NOREPLY is set then we will not send
4596 the away message. This avoids infinite loop of away messages
4597 if both clients are away. The affected file is
4598 lib/silcclient/client_prvmsg.c.
4600 * Fixed client crash if /NICK was given without arguments.
4601 Affected file lib/silcclient/command.c.
4603 * Server does not send the invite list in INVITE command back
4604 to the client if the list was not altered. Added this notion
4605 to the protocol spec as well. Affected file silcd/command.c.
4607 Fixed possible crash in INVITE command by checking the
4608 value of silc_server_get_client_route command.
4610 * Fixed the INVITE notify type handling. The arguments are now
4611 taken in correct order and client does not crash. The affected
4612 file is irssi/src/silc/core/silc-channels.c.
4614 Removed the "Inviting xxx to channel" message from the
4615 client library away and let the application handle it.
4616 Affected file lib/silcclient/command.c. Added that message
4617 to Irssi SILC client's message formats.
4619 * Fixed CMODE command crash in client. It now checks the
4620 amount of arguments correctly and does not crash. The affected
4621 file is lib/silcclient/command.c.
4623 * Do not create new channel automatically in silc_channels_join
4624 but check whether the channel by that name already exists.
4625 Affected file irssi/silc/core/silc-channels.c.
4627 * Do not send the SERVER_SIGNOFF to router if the disconnected
4628 entity was the router. Affected file silcd/server.c.
4630 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4631 SILC client as it was missing from there.
4633 Added the handling of the KICK notify to the Irssi SILC client
4634 as it was missing. Added "you have been kicked" message to
4635 Irssi SILC client's message modules formats.
4637 Added the handing of the KILL notify to the Irssi SILC client
4638 as it was missing. Added the kill message module formats
4641 The affected file is irssi/src/silc/core/silc-channels.c.
4643 * The router did not save the channel mode the server announced.
4644 Affected file silcd/packet_receive.c.
4646 * Fixed a possible crash in INFO command in server. If the
4647 server did not provide the server info it crashed. Affected
4648 file silcd/command.c.
4650 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed the GETKEY command in the server to check also the
4653 global list. Otherwise the GETKEY would not work correctly
4654 in normal SILC server. Affected file silcd/command.c.
4656 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Fixed GETKEY crash, it crashed if the command did not succseed.
4660 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4663 is now real and not just an macro interface to GMP.
4665 Removed the entire GMP from the source tree and imported new
4666 NSS MPI library instead. Reason for removing GMP is that it is
4667 extremely large and compiles extremely slow. The NSS MPI
4668 is only a few files and compiles in less than 10 seconds.
4669 The speed is also about the same as GMP. The MPI is imported
4670 to lib/silcmath/mpi.
4672 If the system has GMP installed we will still use the GMP.
4673 If it is not then the NSS MPI will be compiled.
4675 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Merged a long nickname (127 characters long) crash bugfix from
4678 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4680 * Merged a freed memory reference bugfix from Irssi CVS tree.
4681 Affected file irssi/src/core/commands.c.
4683 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added the server's public key sving and verification to the
4686 server when performing the SKE. This was missing and the
4687 remote server's (or router's) public key was accepted without
4688 checking whether we have it previously or trust it at all.
4689 Affected file silcd/protocol.c.
4691 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Check in the silc_server_timeout_remote if protocol is active
4694 and make sure that the protocol's final callback is called so
4695 that all memory if freed. Affected file silcd/server.c.
4697 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * silc_server_whois_send_reply crashed the server if the nickname
4700 was 127 characters long. Affected file silcd/command.c.
4702 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added sanity check to the silc_server_new_client. If the hostname
4705 is provided inside username then check that the provided hostname
4706 really is the same as the resolved one. If the hostname was not
4707 resolved then check it from the public key. Affected file is
4708 silcd/packet_receive.c.
4710 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4711 if the server disconnected us and the connection is not valid
4712 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4714 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4715 the library to the lib/silcutil/silcutil.[ch].
4717 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Close log file after open. Affected file
4720 lib/silcutil/silclog.c.
4722 * Check whether sock == NULL in silc_client_send_packet and return
4723 if it is. Affected file lib/silcclient/silcclient.c.
4725 * Check rec->entry == NULL in the Irssi SILC Client before
4726 sending the channel message. Affecte file is
4727 irssi/src/silc/core/silc-servers.c.
4729 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Merged a splitted window bugfix from Irssi CVS tree. The
4732 affected file is irssi/src/fe-text/textbuffer-view.c.
4734 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4735 It did not print nickname.
4737 * Improved the distributions system a bit.
4739 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4742 irssi/src/fe-text/gui-window.c.
4744 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4745 to in-active server. The affected file is
4746 irssi/src/silc/core/client_ops.c.
4748 * Resolve the client in USERS command reply if the entry does
4749 not have username resolved. The affected file is
4750 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4751 command to WHOIS command to really resolve stuff. The USERS
4752 is not used any more in any critical section so WHOIS can
4753 be used even though it might be slower than IDENTIFY.
4755 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4758 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Changed the protocol API a bit more consistent in the
4761 lib/silccore/silcprotocol.[ch].
4763 * Changed the following headers to ROBODoc format:
4765 lib/silccore/silcpayload.h
4766 lib/silccore/silcprotocol.h
4767 lib/silccore/silcsockconn.h
4769 All core library headers are now formatted.
4771 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Fixed a bug in Irssi SILC client; do not show that you are
4774 server/router operator if you really are not. Affected file is
4775 irssi/src/silc/core/client_ops.c.
4777 * Renamed silc_command_free_payload to silc_command_payload_free.
4778 Affected file lib/silccore/silccommand.h
4780 * Added silcmath.h to include the prototoypes of various routines
4781 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4784 * Changed the following headers to ROBODoc format:
4786 lib/silccore/silcchannel.h
4787 lib/silccore/silccommand.h
4788 lib/silccore/silcid.h
4789 lib/silccore/silcidcache.h
4790 lib/silccore/silcmode.h
4791 lib/silccore/silcnotify.h
4792 lib/silccore/silcpacket.h
4793 lib/silcmath/silcmath.h
4795 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added checking to the server code not to start the server if
4798 ciphers and stuff are not configured properly. Affected files
4799 silcd/serverconfig.[h] and silcd/server.c.
4801 * Changed the layout of the header files of the public interfaces
4802 in the SILC libraries. The new layout supports ROBODoc
4803 documentation tool (and some others) so that it is easy to create
4804 a library reference manual. All the other headers and source
4805 code must still follow the CodingStyle document. Also source
4806 code must not include these ROBODoc stuffs, only the headers.
4807 Furthermore, all public interface headers must now be named
4808 by using `silc' prefix, example: silcapi.h, silccipher.h.
4809 Some files were renamed due to this. All the other headers
4810 must not be used as public interfaces. I will update the
4811 CodingStyle document later. Changed following headers, so far:
4813 lib/silcclient/silcapi.h
4814 lib/silccore/silcauth.h
4815 lib/silccore/silcprivate.h
4816 lib/silccrypt/silcdh.h
4818 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Removed silc_client_packet_send_flush from the client library
4823 as it is not needed. Affected file lib/silcclient/client.[ch].
4825 * Added printing of message of unresolved authentication method
4826 to the Irssi SILC client. Added it to the module formats.
4827 Removed the same message from the client library.
4829 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Added new distribution feature, DISTLABEL. Every distribution
4832 can define own preprocessor label that can be used in the
4833 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4834 file distributions, acconfig.h.pre and prepare.
4836 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Added Makefile.defines_int to include the actual definitions
4839 for Makefile.defines.in. Tested the new distribution system,
4840 created distributions and tested installation.
4842 * Added AWAY message printing to the Irssi SILC client. Added
4843 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4845 * Added SCONNECT command to call the SILC's CONNECT command.
4846 Cannot use CONNECT directly since Irssi uses that internally.
4847 Affected file irssi/src/silc/core/silc-servers.c.
4849 Added ACTION local command. It is same as ME command but takes
4850 the channel as mandatory argument.
4852 Rewrote some of the Irssi's help files to suite for SILC
4855 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Added Makefile.defines[.in] that should for now on be included
4858 in all Makefile.am file in the source tree. That file includes
4859 all common compilation definitions for SILC source tree.
4861 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Minor changes to the ./prepare script to change the package
4864 name according the distribution name to the configure.in.
4866 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Created new distribution system. Added file `distributions'
4869 that defines all the distributions that can be created out of
4870 the SILC source tree. The ./prepare script now reads that
4871 file to determine how to prepare the distributions. The
4872 first argument to the ./prepare is the name of the distribution
4873 and second is the version of the distribution. If given
4874 without arguments it creates the default (toolkit) distribution
4875 with the default version (defined in ./prepare).
4877 All Makefile.am files that are subject to the distributions
4878 are now named as Makefile.am.pre. These are ./Makefile.am
4879 and lib/Makefile.am. Others may be changed later.
4881 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Added invite list, ban list, some key management and connection
4884 error message printing to module formats in the Irssi SILC client.
4886 * Added new silc_client_set_away_message to set the away message
4887 that is back to the person who sent private message. The
4888 affected file lib/silcclient/silcapi.h and the
4889 lib/silcclient/client_prvmsg.c.
4891 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Fixed the private message sending in the Irssi SILC client,
4894 added local command KEY to the Irssi SILC client.
4896 Added key management and key agreement message formats to the
4897 irssi/src/fe-common/silc/module-formats.[ch].
4899 Added USERS (alias WHO) printing, server/router operator
4900 indication and LIST command printing to the module formats.
4902 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Fixed channel joining notify handling, cumode notify handling
4905 from Irssi SILC client.
4907 * Added SILC specific module-formats to the Irssi SILC client so
4908 that SILC specific message hilighting, colors etc is possible.
4909 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4911 Added channel mode, channel user mode, actions, notices,
4912 whois and whowas printing to the the module-formats.c.
4914 * Fixed a bug in channel deletion in the server. The channel
4915 is not left to the cache even if the channel founder auth mode
4916 is set when there are no users anymore on the channel. Affected
4917 file silcd/server.c.
4919 * The silc_net_localhost now resolves the entire hostname including
4920 the domain name. Affected file lib/silcutil/silcnet.c.
4922 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Changed the ask_passphrase client operation to be ascynchronous.
4925 It has now a completion callback and a context that the
4926 application must call after it has got the passphrase from
4927 the user. Affected files lib/silcclient/silcapi.h,
4928 lib/silcclient/protocol.c, lib/silcclient/command.c and
4931 Added SilcAskPassphrase callback that the application calls
4932 to deliver the passphrase to the library.
4934 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4935 The public key verification and especially a certificate
4936 verification is asynchronous procedure.
4938 Added new SILC_SKE_STATUS_PENDING status to indicate the
4939 request is pending and a callback will be called to finalize
4942 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4943 indicate that remote end did not send its public key (or
4944 certificate), even though we require it. Added check for this
4945 condition in the SKE. This was a security bug, now fixed.
4947 Defined new SilcSKEVerifyCbCompletion callback that is called
4948 when the verification process is completed.
4950 The affected files lib/silcske/silcske_status.h and
4951 lib/silcske/silcske.[ch].
4953 * Changed the verify_public_key client operation to be async
4954 as well. Defined SilcVerifyPublicKey callback that is used to
4955 indicate the success of the public key verification process.
4957 Changed the server and client to use the new async client
4960 * Changed the Irssi SILC client's internal scheduler to be called
4961 twice as many times as it used to be. As a result the client
4962 should be a bit faster now. Affected file is
4963 irssi/src/silc/core/silc-core.c.
4965 * Added support to Irssi SILC client of asynchronous public key
4966 verification and passphrase inquiry. Affected file is
4967 irssi/src/silc/core/silc-core.c.
4969 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Do not say "You have left channel %s" in client library.
4972 Moved it to the application. Affected files are
4973 lib/silcclient/command.c and silc/client_ops.c.
4975 * Fixed silc_client_get_clients. Command context was not
4976 duplicated and was freed memory in the callback. Affected
4977 file lib/silcclient/idlist.c.
4979 * Do not say "you are now talking..." on JOIN command in the
4980 client library. The appliation must handle it.
4982 * Do not say ".. changed topic to" in command reply in the
4983 client libary. The application must handle it.
4985 * Fixed TOPIC command sending in the client library.
4987 * Fixed a memory leak in silc_client_command_free in the file
4988 lib/silcclient/command.c.
4990 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Imported a modified version of Irssi client to the source tree.
4993 The Irssi will be used to create a new client called
4994 Irssi SILC. Imported to irssi/.
4996 Added silc_core_init_finish function to the Irssi. Affected
4997 file irssi/configure.in.
4999 A lot changes in the Makefile.ams around the irssi tree.
5001 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Do not rehash if the new size is same as the old size of the
5004 hash table, in the silc_hash_table_rehash*. The affected file
5005 lib/silcutil/silchashtable.c.
5007 * Replaced hash_table_del_by_context calls from the server
5008 (when channel->user_list and client->channels) to the
5009 hash_table_del as it is sufficient and faster.
5011 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Added silc_hash_table_list, silc_hash_table_get and the
5014 SilcHashTableList structure to provide an alternative way to
5015 traverse the hash table. The affected files are
5016 lib/silcutil/silchashtable.[ch].
5018 * Changed the server's idlist routines to use the hash table
5019 routines to optimize the code.
5021 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Replaced the client entry's `channel' list and channel entry's
5024 `user_list' list to hash tables for optimized lookup. Changed
5025 the code to use the hash table interface around the code.
5026 Affected file lib/silcd/idlist.[ch].
5028 * Added `auto_rehash' boolean argument to the function
5029 silc_hash_table_alloc to indicate whether the hash table should
5030 auto-rehash when it thinks is appropriate time. It will
5031 increase the hash table size if the there is twice as much
5032 entries in the table than the size of the table, and will
5033 decrease the size if there are twice as less entries than
5034 the size of the table.
5036 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5040 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * silc_idcache_purge_by_context deletes the entry now by context
5043 as it is supposed to do. Affected file lib/silccore/idcache.c.
5045 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5046 client is not anymore valid (WHOWAS givens the info) and not
5047 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5049 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Removed the `data' and `data_len' arguments from the ID Cache
5052 interfaces and added `name' argument. ID Cache does not handle
5053 anymore the binary data only a names associated with given ID.
5055 * When hashing a Client ID with silc_hash_id the entire ID is
5056 not hashed anymore, instead only the hash of the Client ID is
5057 hashed. This way we can access the Client ID from the cache
5058 with Client ID but with the hash of the ID (which is a hash of
5059 the nickname) as well without any difference in performance.
5061 Added also silc_idcache_find_by_id_one_ext to do one on one
5062 searching when we have the actual ID. Added also function
5063 silc_hash_client_id_compare. The affected files are
5064 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5066 * When hashing the name associated with a ID it is always done
5067 in lowercase. This way we can access the cache without worrying
5068 about case-sensitivity, even though, for example nicknames are
5071 * Fixed a bug in server with channel message sending. It put
5072 wrong ID type as destination ID. The affected file
5073 silcd/packet_send.c.
5075 * silc_idcache_del_by_context now deletes from all hash tables
5076 by context. Affected file lib/silccore/idcache.c.
5078 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Changed the client library to use the new ID Cache interface.
5081 Changes around the source tree.
5083 * Added silc_hash_table_rehash_ext to rehash with specific
5084 hash function. Affected file lib/silcutil/silchashtable.[ch].
5086 * Added silc_hash_string_compare to compare two strings in the
5087 hash table. Affected file lib/silcutil/silcutil.[ch].
5089 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Added new function silc_idcache_del_by_context into the
5092 lib/silccore/idcache.[ch].
5094 * Changed the server's ID list routines to use the new ID Cache
5095 interface. Changes around the source tree.
5097 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added silc_hash_table_del[_by_context]_ext functions in to the
5100 lib/silcutil/silchashtable.[ch].
5102 Removed silc_hash_table_find_all* routines and added new
5103 silc_hash_table_find_foreach to replace them.
5105 Added silc_hash_table_replace_ext function as extended
5106 replacing function. Separated the simple hash table interface
5107 from the extended hash table interface in the file
5108 lib/silcutil/silchashtable.h.
5110 * Fixed minor bugs and changed it to use some of the new
5111 hash table functions in lib/silccore/idcache.c
5113 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Added new function silc_hash_table_find_all to return all keys
5116 in the hash table by the specified key. As the hash table is
5117 collision resistant it also makes it possible to have several
5118 duplicate keys in the hash table. This function may be used to
5119 find all of the keys from the hash.
5121 Added user_context arguments to the SilcHashFunction,
5122 SilcHashCompare and SilcHashDestructor to deliver user specified
5125 Added new fuctions silc_hash_table_find[_all]_ext to do
5126 extended lookup with specified hash and compare functions and
5127 specified user contexts.
5129 Added new function silc_hash_table_add_ext to add the key
5130 with specified hash function and user context.
5132 Added new function silc_hash_table_foreach to traverse all
5133 entrys in the hash table. Added SilcHashForeach callback
5136 Added new function silc_hash_table_del_by_context to delete
5137 the entry only if the context associated with the key matches.
5139 Affected files are lib/silcutil/silchashtable.[ch].
5141 * Removed silc_hash_[server/client/channel]_id and added just
5142 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5143 silc_hash_id_compare to compare two ID's using as the hash table
5144 comparison function. Added also silc_hash_data to hash
5145 binary data and silc_hash_data_compare to compare it.
5147 * Removed silc_idlist_find_client_by_hash as it is not needed
5148 anymore. Affected file silcd/idlist.[ch].
5150 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5151 to use internally the SilcHashTable. The new ID Cache is a lot
5152 faster than the old one. Some of the ID Cache interface was also
5153 rewritten and obsolete and stupid functions were removed.
5155 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added entry_count field to the SilcHashTable to keep the number
5158 of the entries in the table. Implemented the function
5159 silc_hash_table_rehash. Added new function
5160 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5162 Fixed a minor bug in silc_hash_table_free.
5164 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5165 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5166 into the lib/silcutil/silcutil.[ch].
5168 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Implemented a collision resistant hash table into the
5171 lib/silcutil/silchashtable[ch]. See the header and the source
5172 for the SilcHashTable API.
5174 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Merged dotconf version 1.0.2 into lib/dotconf.
5178 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Do not compile anything in lib/silcsim/* if the SIM support
5181 is not enabled. The tree should now compile without problems
5184 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Compiled the SILC under cygwin. Compiled and tested briefly
5187 without problems. More tests needed. The SIMs didn't compile
5190 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5192 * Fixed possible crash in silc_get_username in the
5193 lib/silcutil/silcutil.c.
5195 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Fixed a va_arg in silc/client_ops.c.
5199 * Oops, RC5 routines were named AES and caused some problems
5200 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5202 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Added new SilcIDIP structure into the lib/silccore/id.h and
5205 replaced the old `ip' fields from all SILC ID's to that type.
5206 This is a step towards IPv6 support.
5208 The silc_id_get_len takes now the ID as an extra argument.
5209 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5210 both IPv4 and IPv6 based ID's.
5212 The affected files are lib/silccore/id.[ch] and other files
5213 around the tree using these routines.
5215 * Removed the ID length arguments in server from various
5216 silc_server_send_notify_* routines -> they are not needed
5219 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Fixed memory leak in silc_encode_pem_file in the file
5222 lib/silcutil/silcutil.c.
5224 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Check minor version as well in the SKE. Affected files are
5227 silcd/protocol.c and lib/silcclient/protocol.c.
5229 * Added --identifier option to the server so that an identifier
5230 can be when creating the public key for the server. Affected
5231 file is silcd/silcd.c.
5233 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5234 lib/silccrypt/silcpkcs.c.
5236 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Register default ciphers and stuff when using -C option with
5239 the server. Affected file sildc/silcd.c.
5241 * Put back the servers public key filename format, it is better
5242 than the new one. For now, the client keys are saved with the
5243 new filename format. The affected file silc/client_ops.c.
5245 * Implemented the Cipher API for the rest of the ciphers that
5246 did not implement it or implemented it the wrong way.
5248 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Register default ciphers and stuff when using the -S option
5251 in the client. Affected file silc/silc.c. Same also when
5252 creating new key pair with -C option.
5254 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Fixed the silc_verify_public_key client operation function to
5257 save the public keys differently. The fingerprint is now
5258 used as filename and not the hostname. This way also the
5259 client keys are saved uniquely and not with hostnames. The
5260 affected file is silc/client_ops.c.
5262 * Trimmed the silc_hash_fingerprint function to remove extra
5263 whitespaces from the end of the fingerprint. The affected
5264 file is lib/silccrypt/silchash.c.
5268 * Added silc_cipher_register_default function to register all
5269 default ciphers. It can be used when configuration files
5270 does not exist and the application does not want any specific
5271 ciphers in any specific order.
5273 The SilcDList is now used as silc_cipher_list dynamically
5274 allocated cipher list. Removed the static list all together
5275 and now all ciphers must be allocated to the dynamic list.
5276 The silc_cipher_alloc routine was changed to check only the
5279 All silc_cipher_* routines that used to return int returns
5282 The affected files lib/silccrypt/silccrypt.[ch].
5284 * The same thing was done to silc_hash_* as for silc_cipher_*
5285 routines. Affected files lib/silccrypt/silchash.[ch].
5287 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5288 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5289 Added also silc_pkcs_[un]register[_default] functions.
5290 Removed the data_context from the PKCS API.
5292 * Added silc_hmac_register_default function to register default
5293 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5294 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5295 to unregister all hmacs at once.
5297 * Register the default ciphers, hash functions, PKCSs and HMACs
5298 if client's configuration file does not exist. The affected
5301 * The client did not load the hash functions from the SIM
5302 modules at all. Added support for this. Affected file is
5303 silc/clientconfig.c.
5305 * When decoding public key with silc_pkcs_public_key_decode, check
5306 the supported algorithm only if PKCS are registered. Affected
5307 file lib/silccrypt/silcpkcs.c. The same was done with the
5308 silc_pkcs_private_key_decode.
5310 * Fixed the SILC List routines to keep the list always in order.
5311 It used to change the list's order when traversing the list but
5312 not it preserves the order. Affected file lib/trq/silclist.h.
5314 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added the client library to use the SilcSocketConnection's
5317 reference counter (by silc_socket_dup) to prevent the bug that
5318 the socket object may be freed underneath async operation.
5320 * The name resolv library checking fixes in the configure.in.pre.
5323 * Created new version of the protocol drafts for future
5324 development. The -03 drafts are the ones that will be changed
5325 in the trunk now and the -02 will remain as they are.
5327 * Send list of CUMODE notifys to the router when announcing
5328 the channel users to the router. Affected file silcd/server.c.
5329 If the router receiving channel founder CUMODE for a channel
5330 that already has channel founder it will send CUMODE notify
5331 to the sender to remove the channel founder rights from the
5332 announced client. Affected file silcd/packet_receive.c.
5334 * The CUMODE notify may now use Server ID as well as the entity
5335 who changes the mode. Updated protocool specs.
5337 * Updated INSTALL and README files.
5339 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * New web pages in the http://silc.pspt.fi. The pages was
5346 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Implemented the [DenyConnectin] config section in the server.
5349 Added silc_server_config_denied_conn to check whether incoming
5350 connection is denied. Affected file silcd/serverconfig.[ch].
5352 * Do not check the ports when checking the incoming configuration
5353 data if the port is 0, meaning any. Affected file is
5354 silcd/serverconfig.c.
5356 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Fixed buffer overflow in silc_string_compare in the file
5359 lib/silcutil/silcutil.c.
5361 * Fixed double free in silc_server_command_leave in the file
5364 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Fixed the version checking in the server. Affected file is
5369 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Fixed the configuration data fetching when accepting new
5372 connections in the server. Affected file silcd/server.c.
5374 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Added `sender_entry' argument to the function
5377 silc_server_packet_relay_to_channel so that we can check
5378 whether some destination actually belongs to the same route
5379 the sender belongs (ie, we must not resend the packet to the
5380 sender). Affected file silcd/packet_send.[ch].
5382 * Added `servername' field to the SilcClientEntry in the server
5383 to hold the name of the server where client is from. Affected
5384 file is silcd/idlist.h.
5386 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Moved the channel message encrypting in the router betwen
5389 router connections from silc_server_channel_message to the
5390 silc_server_packet_relay_to_channel since we want to check
5391 whether we have anybody channel before encrypting anything.
5392 Affected files silcd/packet_[receive/send].c.
5394 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Fixed the [AdminConnection] server config section to support
5397 multiple entries. Affected file silcd/serverconfig.c.
5399 * Added support into the server to check the validity of the
5400 incoming connection before executing any KE or authentication
5403 * The connection configuration is now saved to the KE and
5404 connection auth protocol contexts and not fetched anymore in
5405 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5407 * The local hosts listenning address and port is also resolved
5408 now when starting the server. We want to have the socket object
5409 to include the real address and port for the listener. Added
5410 new function silc_net_check_local_by_sock into the files
5411 lib/silcutil/silcnet.[ch].
5413 * Fixed a broadcast bug in server -> do not broadcast if we
5416 * Fixed a routing bug. Do not route broadcast packets ever.
5417 Broadcast packets must be processed always and not routed since
5418 they may be destined to some other host than yourself and thus
5419 would get routed without no good reason. Affected file is
5422 * Added function silc_server_config_is_primary_route to check
5423 whether primary router connection has been configured (a router
5424 configuration that we are initiating). If there is not, we
5425 will assume that there is only two routers in the SILC network
5426 and we will use the incoming router connection as our primary
5427 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5429 * Changed the order of the broadcasting. Broadcast _after_ the
5430 packet has been processed not before. Affected file is
5433 * Fixed a [ClientConnection] parsing bug. The port was never
5434 parsed correctly thus resulting to port 0. Affected file
5435 silcd/serverconfig.c.
5437 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5438 argument and did not set the broadcast packet flag. Affected
5439 file silcd/packet_send.c. Fixed same bug in the function
5440 silc_server_send_notify as well.
5442 * If we receive NEW_ID packet for our own ID in the server, ignore
5445 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Removed the nickname from the Private Message Payload.
5450 Updated the code and the protocol specs.
5452 * Updated protocol specs for submitting to the IETF.
5454 * Tweaked the Random Number Generator a bit. Affected file
5455 lib/silccrypt/silcrng.c. Exported a new function
5456 silc_rng_[global]_add_noise which can be used to add more
5459 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Do not parse packets with different timeout when protocol
5462 is active -> may cause problem with rekey. Affected file
5465 * When server receives signoff notify it must not create
5466 new channel key if the client is on any channels since the
5467 sender of the signoff notify will create it.
5469 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Added printing of error messages during SKE protocol from the
5472 failure packet sent by server during SKE. Affected file
5475 * Removed the client's failure_callback handling with timeout
5476 and handle it immediately when received.
5478 * The SKE library returned wrong type in SUCCESS and FAILURE
5479 packets. They must be 32 bit MSB not 16 bit MSB.
5481 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Ok, rewrote the logic of the re-key and now it seems to work.
5484 I tested it on high traffic with frequent re-keys without
5485 problems. Added hmac_receive (and renamed hmac to hmac_send)
5486 in SilcClientConnection in lib/silcclient/client.h and
5487 in SilcIDListData in silcd/idlist.h. Also, removed the
5488 SilcPacketParserContext's cipher and hmac fields as they are
5489 not needed anymore and actually caused some problems when
5490 the ciphers and hmac's changed underneath the packet parser.
5492 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * If re-key protocol is active then process the incoming packets
5495 synchronously since we must assure that icoming packets encrypted
5496 with the old key is processed before the new keys is set to
5497 use. This is true other packets than for REKEY packets.
5498 Affected file silcd/server.c. The same was done to client library
5499 as well, affected file lib/silcclient/client.c.
5501 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Fixed bug in client and server to accept the force send if
5504 the packet is send from silc_[server/client]_packet_process
5505 function. Otherwise the packets are never delivered, oops.
5507 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Disable force sending of packets when REKEY protocol is active.
5510 We must assure that no packet is sent directly when rekey is
5511 performed. All packets must be sent through packet queue.
5512 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5513 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5514 function is silc_[server/client]_packet_send_real to check
5517 * Replaced the SIM paths from example config files to
5518 /usr/local/modules. Also, make install creates now
5519 /usr/local/silc/logs directory to hold all the SILC server
5522 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Made the configure.in.pre work on Solaris. Patch by salo.
5526 * Made all ciphers compatible with non-x86 machines. Defined
5527 CBC mode macros into lib/silccrypt/ciphers_def.h.
5529 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Fixed the make install.
5533 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * When MAC computation fails the silc_packet_decrypt returned 0
5536 even though it was supposed to return -1. Fixed this. The
5537 affected file is lib/silccore/silcpacket.c.
5539 * Do not replace the config files in /etc/silc (in make install)
5540 if they already exist. Affected file ./Makefile.am.
5542 * Do not send re-key packets immediately but through packet queue.
5543 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5545 * Changed silc_net_check_host_by_sock to return FALSE if the
5546 IP/DNS could not be resolved. Though, it returns the IP address
5547 now even if it could not resolve it (but returns also FALSE).
5548 Affected file lib/silcutil/silcnet.[ch].
5550 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Added silc_pkcs_decode_identifier to decode the public key's
5553 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5554 Added also silc_pkcs_free_identifier. Added also new context
5555 SilcPublicKeyIdentifier.
5557 * Added -S option to the silc client. It is used to dump the
5558 contents of the specified public key file.
5560 * Changed the PKCS api to return the public key length when
5561 setting the public key.
5563 * Fixed a fatal bug in the public and private key file loading.
5564 Affected file lib/silccrypt/silcpkcs.c.
5566 * Execute the packet parsing for client with zero (0) timeout
5567 if the protocol is active. Affected file silcd/server.c.
5569 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Made the key generation options to the silcd program. Added
5572 -C option, equivalent to client's option.
5574 * Added new [ServerKeys] config section to the server. It
5575 configures the server's public and private key.
5577 * Defined generic Public Key Payload into the protocol
5578 specification to send specific type of public keys and
5581 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5582 public key or certificate.
5584 * Implemented the GETKEY command to the server and to the
5585 client library and on user interface.
5587 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Made preliminary `make install' work.
5591 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Added SilcServerRekey context into silcd/idlist.h.
5595 * Added the PFS support as defined in the specification to the
5596 SKE protocol. Affected files lib/silcske/*.c.
5598 * Added `ske_group' field to the SilcServerRekey context to hold
5599 the number of the SKE group that is used with PFS in re-key.
5600 Affected file silcd/idlist.h.
5602 * Added PFS re-key support to the server. Affected file is
5605 * Added silc_protocol_cancel to cancel execution of the next
5606 state of the protocol. Affected file is
5607 lib/silccore/silcprotocol.[ch].
5609 * Added the re-key support with and without PFS to the client
5610 library. Re-key is performed once in an hour, by default.
5612 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5613 Added silc_client_rekey_callback and silc_client_rekey_final.
5614 Affected files are lib/silcclient/protocol.[ch] and
5615 lib/silcclient/client.[ch].
5617 * Removed the `hmac_key' and `hmac_key_len' fields from the
5618 SilcClientConnection structure; not needed. Affected file is
5619 lib/silcclient/client.h.
5623 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Do not ask whether user wants to use the negotiated private key
5626 for private messages, just use it. Affected file is
5627 silc/local_command.c.
5629 * Added `send_enc_key' and `enc_key_len' fields to the
5630 SilcIDListData structure since they are needed in the re-key
5631 phase. Affected file is silcd/idlist.[ch].
5633 * Implemented the simple re-key protocol into the server.
5634 Affected files silcd/server.c and silcd/protocol.[ch]. The
5635 re-key will be performed once in an hour, by default.
5637 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5638 Added silc_server_rekey, silc_server_rekey_callback and
5639 silc_server_rekey_final.
5641 * Removed Tunneled flag from the protocol. Updated the code
5642 and the specifications.
5644 * Adde `pfs' field to the SilcIDListData to indicate whether
5645 the PFS is to be performed in the re-key. Affected file is
5648 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5651 int64 of at least the xintXX size. If void * is less that 4
5652 bytes uint32 * will be used. Defined bool as boolean.
5654 * Changed _ALL_ unsigned long and unsigned int to uint32,
5655 unsgined short to uint16 in the source tree.
5657 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5658 not handle clients that has entry->data.registered == FALSE.
5659 They are not in the network anymore. Affected file is
5662 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Implemented the sending of the SERVER_SIGNOFF notify in the
5665 server. Affected file is silcd/server.c.
5667 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5668 Added also silc_notify_payload_encode_args into the
5669 lib/silccore/silcnotify.[ch].
5671 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5672 Affected file silcd/packet_receive.c.
5674 * Implemented the SERVER_SIGNOFF notify handling in the client
5675 library. Affected file lib/silcclient/client_notify.c. Also,
5676 implemnted the printing of the SERVER_SIGNOFF info to the
5677 application. Affected file silc/client_ops.c.
5679 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5680 if the deleting was successful. Affected file silcd/idlist.[ch].
5682 * Added support for public key authentication in the connection
5683 authentication protocol in the client library. Affected file
5684 lib/silcclient/protocol.c.
5686 * Changed the server's silc_idlist_get_clients_by_* interface
5687 to support already allocated array so that new entries may be
5688 added to pre-allocated array. Affected file silcd/idlist.[ch].
5689 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5690 and command replies.
5692 * All command reply functions in the server now calls the
5693 pending command callback even if error occured. This way the
5694 error will be delivered to the client as well. Affected files
5695 silcd/command.c and silcd/command_reply.c.
5697 * Fixed INFO command to return local server's info if no server
5698 was provided. Affected file lib/silcclient/command.c.
5700 * Removed RESTART command for good. Updated the code and the
5703 * Rewrote parts of the task system. It is a bit simpler now.
5704 Removed unsued task priorities. The affected files are
5705 lib/silcutil/silctask.[ch].
5707 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Moved the USERS printing from the library to the application.
5710 Affected files lib/silcclient/command.c and silc/client_ops.c.
5712 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added channel key re-key support. The re-key is perfomed
5717 only by the router and is done once in an hour. Added `rekey'
5718 field to the SilcChannelEntry in the server. Affected files
5719 silcd/server.c and silcd/idlist.h.
5721 * Added silc_task_unregister_by_context into the file
5722 lib/silcutil/silctask.[ch].
5724 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added SILC_UMODE_GONE mode to indicate when the client is not
5727 present in the SILC network. Added also support to the local
5728 command AWAY that will set this mode. Added support of showing
5729 "xxx is gone" in WHOIS command. The USERS command shows the
5730 gone status as well.
5732 * Fixed setting server and router operator privileges in the
5733 server's UMODE command. Affected file silcd/command.c.
5735 * Merged the SKE KE1 and KE2 payloads into one payload. The
5736 new KE payload is equivalent to the old KE2 payload.
5738 Cleaned up the SKE Start Payload parsing. It now uses the
5739 simple buffer unformatting to do the parsing. A lot faster
5742 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5743 to the SKE that is used to indicate whether both of the SKE
5744 parties should perform authentication. By default only the
5745 responder performs authentication. By setting this flag also
5746 the initiator must do authentication. By default it is unset
5747 since in normal SKE case, client to server connection, only
5748 the responder should do authentication. When doing SKE between
5749 two clients both should perform authentication. Updated the
5750 code and the protocol specs.
5752 * A little fix to IDENTIFY command in the server. Search the
5753 client first by hash not nickname. Affected file is
5756 * Fixed the silc_client_close_connection to support closing
5757 the client to client connections wihtout deleting too much
5758 data. Affected file lib/silcclient/client.c.
5760 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5761 are received if protocol used to be active but is not anymore
5762 the application would crash due to NULL pointer dereference.
5763 Affected files silcd/server.c and lib/silcclient/client.c.
5765 * Added `hash' field to the SilcClientConnection to include
5766 the hash function negotiated in the SKE protocol.
5768 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5769 to set the channel founder authentication data. A client can
5770 claim the founder rights later by providing the authentication
5771 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5772 This way the channel founder can regain the channel founder
5773 privileges even it is left the channel. This works only on
5774 local server and the client must be connected to the same
5775 server to be able to regain the founder rights. Updated the
5776 protocol specs accordingly.
5778 Added support to the CMODE command in the client to set the
5779 founder auth data. Read the README to see how to set it.
5781 Added support to the CUMODE command to claim the founder
5782 rights. Read the README to see how to do it.
5784 Added support for the founder authentication to the Channel
5785 Entry in the server. Affected file silcd/idlist.h.
5787 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5788 server's CMODE command. Affected file silcd/command.c.
5790 * Added the following new functions into lib/silccore/silcauth.[ch]:
5791 silc_auth_get_method and silc_auth_get_data.
5793 * The server now saves the remote hosts public key to the
5794 SilcIDListData pointer. Affected file silcd/protocol.c.
5796 * The normal server now does not remove the channel entry from
5797 the cache if the founder authentication data is set. It used
5798 to remove it if the founder was the last one on the channel on
5799 the server and left the channel. The auth data is saved and
5800 if the channel is re-joined later the old entry is used with
5801 the old auth data. Affected files silcd/command_reply.c and
5804 * Removed the `pkcs' field from the SilcIDListData structure
5805 in the server; it is not used. Affected file silcd/idlist.h.
5807 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Fixed packet processing on slow links. Partial packets were
5810 never re-processed because the incoming data buffer was cleared
5811 by the application. Application must not directly clear the
5812 sock->inbuf, the packet processing routines handle it. Fixed
5813 this in client library and in server.
5815 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Fixed the WHOIS and IDENTIFY send reply function to really
5818 check whether to send list or just one entry. Affected file
5821 * Cleaned up the LEAVE command's channel key distribution. The
5822 affected file silcd/command.c.
5824 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5825 can enforce the channel mode as well. In that case the ID
5826 includes the ID of the server. The code now enforces the
5827 mode change if the router have different mode than the server.
5829 * The notify client operation with CMODE_CHANGE notify can now
5830 return NULL client_entry pointer if the CMODE was not changed
5831 by client. Application must check for this.
5833 * Added <Server ID> argument to INFO command to support server
5834 info fetching by Server ID.
5836 * Added silc_server_announce_get_channel_users to get assembled
5837 packets of channel users of the specified channel. Affected
5838 file silcd/server.[ch].
5840 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5841 was freed underneath the ID Cache.
5843 * Re-announce clients when the server received CHANNEL_CHANGE
5844 notify from the router. Affected file silcd/packet_send.c.
5846 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5849 crashed since it did not handle the fact that there is no cipher
5850 called "3" and didn't check the error condition. Now fixed.
5852 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5853 flag. It can be used to send message requests.
5855 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Implemented the RESTART command in the client.
5859 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5860 notice type messages. Added notice printing to the user
5863 * The channel keys are not re-generated if the channel's mode
5864 is PRIVKEY, ie private key on the channel exists. Affected
5865 files silcd/server.c and silcd/command.c.
5867 * Fixed a little bug in channel message delivery when channel
5868 private keys are set in the server. Affected file is
5869 silcd/packet_send.c.
5871 * Changed the setting on channel->on_channel = TRUE from the
5872 silc_client_save_channel_key to the JOIN command reply. The
5873 key payload is not received if the private channel key is set.
5874 Affected file lib/silcclient/command_reply.c and the
5875 lib/silcclient/client_channel.c.
5877 * When the CMODE_CHANGE notify is sent and the channel private
5878 key mode is removed the channel key must be re-generated in
5879 other cells as well. Added this support for the router in the
5880 silcd/packet_receive.c.
5882 * Added new local command NOTICE to send notice message on
5883 channel. Affected file silc/local_command.[ch].
5885 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Added new local command ME to the client. It is used to send
5888 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5889 some action. Affected file silc/local_command.[ch].
5891 * Changed channel_message and private_message client operations
5892 to deliver the message flags to the application. Added also
5893 the `flags' arguments to the silc_client_send_channel_message
5894 and silc_client_send_private_message functions. Affected file
5897 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Redefined the Private Message Payload to support private message
5900 keys and to support the new private message flags. Updated
5901 the protocol specs. Flags makes it possible to have for example
5902 CTCP style messages.
5904 * Added new type SilcPrivateMessagePayload and defined an API
5905 for it in the lib/silcclient/silcprivate.[ch].
5907 * Tested private message private keys successfully. Tested the
5908 private message key set, unset and list commands with the new
5911 * Redefined the Channel Message Payload to include the channel
5912 message flags (equal with private message flags) to support
5913 for example CTCP style messages.
5915 * Defined some of the message (for channel and private message)
5916 flags. Updated the protocol specs and added the flags to the
5917 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5919 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added SilcKeyAgreementStatus type to the key agreement routines
5922 to indicate the current status and error if one occured.
5923 The status types are defined in the lib/silcclient/silcapi.h.
5925 * Added new local command KEY that is used to set and unset private
5926 keys for channels, set and unset private keys for private messages
5927 with remote clients and to send key agreement requests and
5928 negotiate the key agreement protocol with remote client. The
5929 key agreement is supported only to negotiate private message keys,
5930 it currently cannot be used to negotiate private keys for channels,
5931 as it is not convenient for that purpose.
5933 * Fixed a minor pending callback setting bug in the function
5934 silc_client_get_client_by_id_resolve, now the function works.
5935 Affected file lib/silcclient/idlist.c.
5937 * Added function silc_net_get_local_port to get local bound
5938 port by socket. Added to lib/silcutil/silcnet.[ch].
5940 * Added `sockets' and `sockets_count' fields to the SilcClient
5941 object. They hold the sockets of the listenning sockets in
5942 the client. Listenning sockets may be for example the key
5943 agreement server. Affected file lib/silcclient/client.[ch].
5944 Added functions the silc_client_add_socket and the
5945 silc_client_del_socket. They are exported to the application
5948 * Added ~./silc/clientkeys to support other client's public keys.
5950 * Renamed verify_server_key client operation to verify_public_key
5951 and added one argument to indicate the type of the connection
5952 (server, client etc.).
5954 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added silc_server_connection_auth_request to handle the
5957 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5958 silcd/packet_receive.[ch].
5960 * Added silc_server_send_connection_auth_request into the
5961 silcd/packet_send.c to send the connection auth request packet.
5963 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5966 * Fixed the public key authentication in responder side in the
5967 server. The `auth_data' pointer includes the SilcPublicKey
5968 not the path to the public key. Affected file silcd/protocol.c.
5970 * Implemented the public key authentication in the initiator side
5971 in the server. Affected file silcd/protocol.c.
5973 * Removed the [RedirectClient] config section from the server
5974 configuration. Is not needed and I don't want to implement it.
5976 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Cleaned up the CMODE command in the server. It now works
5979 correctly and supports all the modes defined in the protocol.
5980 Affected file is silcd/command.c.
5982 * Added `hmac_name' field to the SilcChannelEntry in the server
5983 to hold the default HMAC of the channel. It can be set when
5984 creating the channel (with JOIN command). Affected files
5987 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5988 type to indicate the change of the current cipher and hmac
5989 on the channel. Client can safely ignore the <cipher> argument
5990 (if it chooses to do so) since the CHANNEL_KEY packet will
5991 force the channel key change anyway. The <hmac> argument is
5992 important since the client is responsible of setting the new
5993 HMAC and the hmac key into use.
5995 * Fixed the CMODE command in the client library as well.
5997 * Tested CMODE command in router environment successfully.
5999 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Show the version of the remote client (or server) when connecting
6002 to the server. It is logged to the log file. Affected file
6003 is silcd/protocol.c.
6005 * Fixed the KILLED notify handling in the client library. The
6006 client must be removed from all channels when receiving the
6009 Also, do not remove the client entry when giving the KILL
6010 command but when the KILLED notify is received.
6012 * Removed silc_idlist_find_client_by_nickname from the server.
6013 Not needed anymore. Affected files silcd/idlist.[ch].
6015 * Implemented the CHANNEL_CHANGE notify type handling to the
6016 server. Affected file silcd/server.c.
6020 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Added silc_server_send_notify_invite to send the INVITE
6023 notify between routers.
6025 * Implemented the INVITE command correctly to the server.
6027 * Implemented the INVITE notify type handling in the server.
6029 * Implemented the INVITE command to the client library and on the
6032 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added function silc_server_get_client_resolve to find the
6035 client entry by ID from all ID lists and then resolve it
6036 (using WHOIS) if it cannot be found. Affected file is
6039 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Implemented the BAN command to the client library.
6043 * The JOIN command in the server now checks the invite list
6046 * Changed the silc_command_reply_payload_encode_va and the
6047 silc_command_payload_encode_va to support that if argument is
6048 NULL it ignores and checks the next argument. Affected file
6049 lib/silccore/silccommand.c.
6051 * Added silc_server_send_notify_ban to send the BAN notify
6052 type between routers.
6054 * Chaned the silc_notify_payload_encode to support that if
6055 argument is NULL it ignores and checks the next argument.
6056 Affected file lib/silccore/silcnotify.c.
6058 * Tested ban lists in router environment successfully.
6060 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Implemented BAN command to the server, in silcd/command.[ch].
6064 * Removed the BAN and INVITE_LIST modes from the CMODE command
6067 * Added function silc_string_match to regex match two strings.
6068 Affected files lib/silcutil/silcutil.[ch].
6070 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Redefined parts of the SilcChannelEntry in the server to support
6073 the new ban and invite lists.
6075 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Redefined the INVITE command. The same command can be used to
6078 invite individuals to the channel but also to manage the invite
6079 list of the channel (to add to and remove from the invite list).
6080 Updated the protocol specs.
6082 * Added new command SILC_COMMAND_BAN that can be used to manage
6083 the ban list of the channel. Updated the protocol specs.
6085 * Removed the channel modes: the SILC_CMODE_BAN and the
6086 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6087 in the CMODE command. The equivalent features are now available
6088 using INVITE and BAN commands. Updated the protocol specs.
6090 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6091 in the network about change in the current ban list. The notify
6092 type is not used by the client.
6094 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6095 support the invite lists.
6097 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Added new function silc_string_regexify that converts string
6100 including wildcard characters into regex string that can
6101 be used by the GNU regex library. Added into the file
6102 lib/silcutil/silcutil.[ch].
6104 Added silc_string_regex_combine to combine to regex strings
6105 into one so that they can be used as one regex string by
6106 the GNU regex library. Added into the file
6107 lib/silcutil/silcutil.[ch].
6109 Added silc_string_regex_match to match two strings. It returns
6110 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6112 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Imported GNU regex to the soruce tree into lib/contrib.
6115 Fixed some compiler warning from the regex.c.
6117 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Fixed MOTD command in the server to work in router environment.
6121 * Fixed the MOTD command in the client library to support
6122 the server argument in the command.
6124 * Added `nickname_len' argument to the silc_idlist_add_client
6125 in the server, as the `nickname' argument may be binary data
6128 * Added silc_idlist_get_channels to return all channels from
6131 * Implemented LIST command to the server. Affected file is
6134 * Implemented the LIST command to the client library and on the
6137 * Added [<user count>] argument to the LIST command reply.
6138 With private channels the user count is not shown.
6140 * Updated TODO and README.
6142 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * The client entry's data.registered must be TRUE even with
6145 global client entry on global client list. The data.registered
6146 is used to check whether the client is anymore in the network,
6147 for example with WHOWAS command so it must be valid.
6149 * Fixed the WHOWAS command in the server. It now actually works
6150 in router environment. Added function into silcd/command_reply.c
6151 silc_server_command_reply_whowas_save.
6153 * Added silc_idlist_purge function to the silcd/idlist.c
6154 to periodically purge the ID Cache.
6156 * Fixed INFO command in the server. It works now in router
6157 environment. Added <server name> argument to the INFO command
6158 reply. Updated the protocol specs.
6160 * Fixed minor bug in silc_idcache_purge to not purge if the
6161 expire value is zero.
6163 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6164 they were buggy because of the WHOWAS information.
6166 * Fixed local command MSG to handle the async resolving of
6167 the remote client properly. It used to fail the first MSG.
6168 Affected file silc/local_command.c.
6170 * Added `data_len' field to SilcIDCache context.
6172 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Update TODO. Todo in commands in the server.
6176 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6179 used by routers as broadcast packet to inform other routers
6180 about the changed user mode.
6182 Implemented the notify handling in the server. Affected file is
6183 silcd/packet_receive.c. Added the function
6184 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6186 * Added new generic Channel Payload and deprecated the New Channel
6187 Payload. The New Channel Payload is now the generic Channel
6190 * Added new argument `mode' to the silc_server_send_new_channel
6191 as it is required in the Channel Payload now.
6193 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6194 and created a new and real SilChannelPayload to represent the
6195 new generic Channel Payload. Implemented the encode/decode
6196 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6198 * Added silc_server_get_client_channel_list to return the list
6199 of channels the client has joined for WHOIS command reply.
6200 Affected file silcd/server.[ch].
6202 * Implemented the channel list sending in the WHOIS command reply
6203 in server and in the client.
6205 Implemented the channel list displaying on the user interface
6206 as well. Affected file silc/client_ops.c.
6208 * Added silc_channel_payload_parse_list to parse list of Channel
6209 Payloads. It returns SilcDList list of SilcChannelPayloads.
6210 Client for example can use this function to parse the list of
6211 channels it receives in the WHOIS command reply. The caller
6212 must free the list by calling silc_channel_payload_list_free.
6213 Affected files lib/silccore/silcchannel.[ch].
6215 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Added one new argument <user mode> to the WHOIS command reply
6218 to return the mode of the user in SILC. Updated the protocol
6221 Implemented it to the server and client.
6223 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Fixed the mode printing on the user interface on joining.
6226 Affected file silc/client_ops.c.
6228 * Implemented the UMODE command and user modes in general to the
6229 client library and to the user interface.
6231 * Implemented the UMODE command to the server.
6233 * The server now sends UNKNOWN_COMMAND error status if client sends
6234 unknown command. Affected file silcd/command.c.
6236 * All server commands now handle the command identifier the right
6237 way when sending the command reply to the client. The client can
6238 use to identify the command replies with the identifier.
6240 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Added silc_server_get_client_route to resolve the route to
6243 the client indicated by the client ID. Affected file is
6246 * Added silc_server_relay_packet as general function to relay
6247 packet to arbitrary destination. This deprecates functions
6248 like _send_private_message_key, _relay_notify etc. Affected
6249 file is silcd/packet_send.[ch].
6251 Removed silc_server_send_key_agreement,
6252 silc_server_send_private_message_key and
6253 silc_server_packet_relay_notify functions from the file
6254 silcd/packet_send.[ch].
6258 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6259 server. Affected file silcd/packet_receive.[ch].
6261 * Implemented the KILL command to the client. Implemented the
6262 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6263 Affected files lib/silcclient/command[_reply].c and
6264 lib/silcclient/client_notify.c. Implemented the KILL notify
6265 printing in the user inteface.
6267 * Fixed a lot silc_parse_nick memory leaks from the client
6268 library in the file lib/silcclient/command.c.
6270 * Changed the silc_server_send_notify_on_channels's `sender'
6271 argument from SilcSocketConnection to SilcClientEntry to
6272 check the sender as entry and not as connection object and not
6273 to send to the client provided as argument. The affected file
6274 is silcd/packet_send.[ch].
6276 * The notify packets that are destined directly to the client used
6277 to not to be processed by the server. Now changed that and the
6278 server processes all notify packets. After relaying the packet
6279 to the client the notify packet is processed in the server.
6281 * The silc_server_free_client_data now checks whether there is
6282 pending outgoing traffic for the client and purges the data to
6283 the network before removing the client entry.
6285 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6288 an client is killed from the SILC Network. Updated the protocol
6291 Added new function silc_server_send_notify_killed to the
6292 silcd/packet_send.[ch].
6294 * Added function silc_server_packet_relay_notify to relay notify
6295 packets that are destined directly to a client. In this case
6296 the server does not process the notify packets but merely relays
6297 it to the client. Affected file silcd/packet_send.[ch].
6299 Added also silc_server_packet_process_relay_notify to check
6300 whereto relay the notify. Affected file is
6301 silcd/packet_receive.[ch].
6303 * Implemented the KILL command to the server.
6307 * Added the backup schema desgined last fall to the protocol
6308 specs for everyone to see. The specification is in the
6309 *-spec-xx.txt draft and the packet type definitions for the
6310 backup routers is in *-pp-xx.txt draft. Thusly, added also
6311 new packet type SILC_PACKET_CELL_ROUTERS.
6313 * A big security problem in the implementation discovered. The
6314 signoff of an client did not cause new channel key generation
6315 which it of course should've done. The channel keys must be
6316 always re-generated when client leaves (or signoffs) the channel.
6317 The silc_server_remove_from_channels funtion now handles
6318 the channel key re-generation.
6320 * Added `sender' argument to the silc_server_send_notify_on_channels
6321 to not to send the client provided as argument. Affected file
6322 silcd/packet_send.[ch].
6324 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Implemented OPER and SILCOPER commands into the server and
6329 * Added silc_auth_verify and silc_auth_verify_data to verify
6330 the authentication directly from the authentication payload.
6331 It supports verifying both passphrase and public key based
6332 authentication. Affected file lib/silccore/silcauth.[ch].
6334 * Added `hash' field to the SilcIDListData structure. It is the
6335 hash negotiated in the SKE protocol. Affected file is
6338 * Slight redesigning of the SilcAuthPayload handling routines.
6339 Do not send SilcPKCS but SilcPublicKey as argument.
6341 * Implemented the public key authentication support to the
6342 serverconfig. The public key is loaded from the provided path
6343 and saved as authentication data to void * pointer. Thus,
6344 changed the unsigned char *auth_data to void *auth_data;
6346 * Fixed SHUTDOWN command to send the reply before the server
6347 is shutdown. :) Affected file silcd/command.c.
6349 * Fixed fatal bug in CONNECT command. The hostname was invalid
6350 memory and server crashed. Affected file silcd/command.c.
6352 * Fixed fatal bug in CLOSE command. The server_entry became
6353 invalid but was referenced later in the command. Affected file
6356 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Fixed fatal bug in failure packet handling. Server ignored
6359 the failure and thus crashed when it came.
6363 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6366 that the command may be executed only once in (about) 2 seconds.
6367 The old SILC_CF_LAG flag is same but allows command bursts up
6368 to five before limiting.
6370 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6371 server code. Various commands now includes the CF_LAG_STRICT
6372 flag to disallow any kind of miss-use of the command.
6374 * Fixed the silc_buffer_unformat to not to allocate any data
6375 if the length of the data is zero. It used to allocate the
6376 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6378 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Changed the format of AdminConnection configuration section
6381 in the server. Added username of the admin to the format.
6382 Affected files silcd/serverconfig.[ch].
6384 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6385 to return admin configuration data by host, username and/or
6388 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Implemented WHOWAS command to the server. Added the functions:
6392 silc_server_command_whowas_parse,
6393 silc_server_command_whowas_send_reply,
6394 silc_server_command_whowas_from_client and
6395 silc_server_command_whowas_from_server
6397 * Added <Client ID> argument to the WHOWAS command reply. Updated
6398 the protocol specs accordingly.
6400 * Implemented WHOWAS command and command_reply to the client
6403 Implemented the WHOWAS printing on the user interface.
6405 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6407 * Added new argument to the WHOWAS command reply, the real name.
6408 It is an optional argument. Updated the protocol specs.
6410 * Added SilcIDCacheDestructor callback that is registered when
6411 the SilcIDCache is allocated. The callback is called when
6412 an cache entry in the ID Cache expires, or is purged from the
6413 cache. Added into lib/silccore/idcache.[ch].
6415 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6416 to destruct the client entries when the cache entry expires.
6417 Other ID Cache's in server and in the client library ignores
6420 * If the ID Cache entry's `expire' field is zero then the entry
6421 never expires. Added boolean `expire' argument to the
6422 silc_idcache_add function in the lib/silccore/idcache.[ch].
6423 If it is TRUE the default expiry value is used.
6425 * Added silc_server_free_client_data_timeout that is registered
6426 when client disconnects. By default for 5 minutes we preserve
6427 the client entry for history - for WHOWAS command.
6429 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Added support to the server to enforce that commands are not
6432 executed more than once in 2 seconds. If server receives
6433 commands from client more frequently, timeout is registered
6434 to process the commands. Affected file silcd/command.c.
6435 Added new function silc_server_command_process_timeout.
6437 * Changed NICK_NOTIFY handling in client library to check that
6438 if the client's nickname was changed, so there is no need to
6439 resolve anything from the server.
6441 * Removed error printing from the WHOIS and IDENTIFY commands.
6442 If error occurs then it is ignored silently in the client library.
6443 The application, however, may map the received error to
6444 human readable error string. The application currently maps
6445 the NO_SUCH_NICKNAME error to string.
6447 * Made the command status message public to the application. Moved
6448 them from lib/silcclient/command_reply.c to
6449 lib/silcclient/command_reply.h. The application can map the
6450 received command status to the string with the
6451 silc_client_command_status_message function.
6453 * Added check to the server to check that client's ID is same
6454 as the Source ID in the packet the client sent. They must
6457 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Added dist-bzip hook to the Makefile.am to make bzip2
6460 compressed distributions.
6462 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Server now enforces the maximum length for the nickname and
6465 the channel as protocol specification dictates. 128 bytes for
6466 nickname and 256 bytes for channel name.
6468 * Moved the WHOIS printing to the application. The client libary
6469 does not print out the WHOIS information anymore, the application
6470 must do it. Renamed silc_client_command_reply_whois_print to
6471 the silc_client_command_reply_whois_save.
6473 The client's idle time is also sent to the application now, and
6474 the idle is shown on screen.
6476 * Added silc_client_command_reply_identify_save to save the
6477 received IDENTIFY entries.
6479 * Do not check for channel private keys in message sending and
6480 reception if the channel does not have the PRIVKEY mode set.
6481 Affected file lib/silclient/client_channel.c.
6483 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6486 just surfaced after chaning the JOIN procedure.
6488 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Added silc_client_get_clients_by_list to get client entries
6491 from Client ID list, that is returned for example by JOIN
6492 and USERS command replies. The application should use this
6493 function for example when JOIN command reply is received to
6494 resolve the clients already on the channel (library does not
6495 do that anymore as USERS command reply is not used in the JOIN
6496 procedure anymore). Affected files lib/silcclient/silcapi.h and
6497 lib/silcclient/idlist.c.
6499 * JOIN command reply and USERS command reply returns now SilcBuffer
6500 pointers instead of unsigned char pointers when returning
6501 the client list and mode list.
6503 * Added <Client ID> argument to the JOIN command reply, mainly
6504 for the server to identify for which client the command was
6505 originally sent. Updated protocol specs accordingly.
6507 * Added SilcDlist private_key pointer to the SilcChannelEntry
6508 in the client to support the channel private keys. Affected
6509 file is lib/silcclient/idlist.h.
6511 * Added SilcChannelPrivateKey argument to the function
6512 silc_client_send_channel_message so that application can choose
6513 to use specific private ke if it wants to. If it is not provided,
6514 the normal channel key is used, unless private keys are set.
6515 In this case the first (key that was added first) is used
6516 as the encryption key.
6518 * Implemented the support for channel private key handling.
6519 Implemented the following functions:
6521 silc_client_add_channel_private_key,
6522 silc_client_del_channel_private_keys,
6523 silc_client_del_channel_private_key,
6524 silc_client_list_channel_private_keys and
6525 silc_client_free_channel_private_keys
6527 Affected file lib/silcclient/client_channel.c.
6529 * Added the support for the private keys in the channel message
6530 sending and encryption and in the message reception and
6531 decryption. Affected funtions are
6532 silc_client_send_channel_message and silc_client_channel_message.
6534 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added SKE's key verify callback to the client library's
6537 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6539 * Removed the statement that server (or router) must send USERS
6540 command reply when joining to the channel so that the client
6541 knows who are on the channel. Instead, the client list and
6542 client's mode list is now sent in the JOIN command reply to the
6543 client who joined channel. This is better solution.
6545 * Added function silc_server_get_users_on_channel and function
6546 silc_server_save_users_on_channel to the silcd/server.[ch].
6548 * Removed function silc_server_command_send_users from the
6551 * Do not show topic on the client library anymore. The topic is
6552 sent in the command reply notify to the application and the
6553 application must show the topic now.
6555 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Added client searching by nickname hash into the IDENTIFY and
6558 WHOIS commands in the server as they were clearly missing from
6559 them. Affected file is silcd/command.c.
6561 * Fixed a bug in private message receiving in the client library.
6562 The remote ID was freed and it wasn't supposed, now it is
6565 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Minor fix to the channel payload; allocate the data area, as it
6568 needs to be of specific length.
6570 * If the key agreement port is zero then the operating
6571 system will define the bound port. Affected files are
6572 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6574 * Added new function silc_channel_payload_decrypt into the file
6575 lib/silccore/silcchannel.[ch].
6577 * Moved the channel message etc, check from silc_packet_decrypt
6578 to applications. The library calls now a generic
6579 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6580 when the packet is either normal or special. This was done to
6581 allow more wide range of checking that was not allowed when
6582 the code was in library. Now applications can do virtually any
6583 checks to the packet and return to the library the decision how
6584 the packet should be processed. Affected files are
6585 lib/silccore/silcpacket.[ch].
6587 Added silc_server_packet_decrypt_check to the server and
6588 silc_client_packet_decrypt_check to the client library.
6590 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6591 to send with specified source and destination information.
6593 * Channel message delivery between routers was broken after the
6594 channel key distribution was fixed earlier. The channel key
6595 was used be to distributed to other routers as well which is not
6596 allowed by the protocol. Now this is fixed and channel keys
6597 really are cell specific and the channel message delivery between
6598 routers comply with the protocol specification.
6600 * Fixed various commands in server to check also the global list
6601 for the channel entry and not just the local list. The affected
6602 file silcd/command.c.
6604 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Added assert()s to buffer formatting and unformatting routines
6607 to assert (if --enable-debug) when error occurs. Affected
6608 file: lib/silcutil/silcbuffmt.c.
6610 * Changed to auto-reconnect to check whether the remote host is
6611 router and register the re-connect timeout if it is. It used
6612 to check that whether we are normal server, but router must do
6613 auto-reconnect with another router as well. Affected file
6616 * Removed the [<key len>] option from CMODE command as the cipher
6617 name decides the key length, nowadays. See the defined ciphers
6618 from the protocol specification.
6620 * Added [<hmac>] option to the CMODE command to define the HMAC
6621 for the channel. Added SILC_CMODE_HMAC channel mode.
6623 * Added [<hmac>] option for the JOIN command so that user can
6624 select which HMAC is used to compute the MACs of the channel
6627 * Added Hmac field to the Channel Message Payload. The integrity
6628 of plaintext channel messages are now protected by computing
6629 MAC of the message and attaching the MAC to the payload. The
6630 MAC is encrypted. Now, it is clear that this causes some
6631 overhead to the size of the packet but rationale for this is that
6632 now the receiver can verify whether the channel message decrypted
6633 correctly and also when private keys are set for the channel the
6634 receiver can decrypt the packet with several keys and check from
6635 the MAC which key decrypted the message correctly.
6637 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6638 lib/silccrypt/silccipher.[ch].
6640 * Added silc_hash_len to return the digest length into the
6641 lib/silcrypt/silchash.[ch].
6643 * Rewrote parts of Silc Channel Payload interface in the
6644 lib/silccore/silcchannel.[ch]. The encode function now also
6645 encrypts the packet and parse function decrypts it.
6647 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Fixed a minor formatting bug in the SKE's key material processing.
6650 It actually might have processed the keys wrong way resulting
6653 * Redefined the mandatory HMAC algorithms and added new algorithms.
6654 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6655 and hmac-md5 truncated to 96 bits. The mandatory is now
6656 hmac-sha1-96. Rest are optional (including the one that used
6657 to be mandatory). Rationale for this is that the truncated HMAC
6658 length is sufficient from security point of view and can actually
6659 make the attack against the HMAC harder. Also, the truncated
6660 HMAC causes less overhead to the packets. See the RFC2104 for
6663 * Added new [hmac] configuration section. The SKE used to use
6664 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6665 is of course wrong. The official names that must be proposed in
6666 the SKE are the ones defined in the protocol specification
6667 (hmac-sha1-96 for example). The user can configure any hmac
6668 using any hash function configured in the [hash] section. At
6669 least, the mandatory must be configured.
6671 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6673 * Added HMAC list to the SKE proposal list. It has now both
6674 hash algorithm list and HMAC list. This makes the protocol
6675 incompatible with previous versions. The SKE now seems to work
6676 the way it is supposed to work, for the first time actually.
6678 * Defined plain Hash algorithms to the protocol specification.
6681 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Implemented support for key agreement packets into the server.
6684 Added functions silc_server_key_agreement and
6685 silc_server_send_key_agreement. Other than these functions,
6686 server has nothing to do with this packet.
6688 * Added support for private message key packets into the server.
6689 Added functions silc_server_private_message_key and
6690 silc_server_send_private_message_key.
6694 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6695 called in the protocol's final callback instead in the END
6696 protocol state. This makes a little more sense and in the same
6697 time in client we can use the same protocol routines for normal
6698 key exchange and to key agreement packet handling as well.
6700 * Added to both client's and server's KE protocol context the
6701 SilcSKEKeyMaterial pointer to save the key material. We will
6702 bring the key material to the protocol's final callback by doing
6703 this. The final callback must free the key material.
6705 * Added SKE's packet_send callback into client's KE protocol
6706 context so that the caller can choose what packet sending function
6707 is used. This way we can use different packet sending when
6708 doing normal SKE when doing key agreement packet handling (in
6709 the key agreement packet handling we do not want to encrypt
6712 * Implemented the responder side of the key agreement routines
6713 in the client. The client can now bind to specified port and
6714 accept incoming key negotiation. The key material is passed
6715 to the application after the protocol is over.
6717 * Implemented the processing of incoming Key Agreement packet
6718 in the client. Added function silc_client_key_agreement to
6721 * Implemented the intiator side of the key agreement routines
6722 in the client. The client can now initiate key agreement with
6723 another remote client. The key material is passed to the
6724 application after the protocol is over.
6726 * Created client_keyagr.c to include all the key agreement
6729 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6730 SILC_TASK_CALLBACK except that it is not static.
6732 * Created client_notify.c and moved the Notify packet handling
6733 from the client.[ch] into that file.
6735 * Created client_prvmsg.c and moved all private message and
6736 private message key routines from the client.[ch] into that file.
6738 * Create client_channel.c and moved all channel message and
6739 channel private key routines from the client.[ch] into that file.
6741 * Changed silc_client_get_client_by_id_resolve to resolve with
6742 WHOIS command instead of IDENTIFY command, in the file
6743 lib/silclient/idlist.c.
6745 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Implemented the SKE's responder side to the Client library.
6749 * When FAILURE is received to the protocol do not trust it
6750 blindly. Register a timeout to wait whether the remote closes
6751 the connection as it should do it, only after that process the
6752 actual failure. This was changed to both client and server.
6754 * Added client_internal.h to include some of the structures
6755 there instead of client.h in lib/silcclient/.
6757 * Added function silc_task_unregister_by_callback to unregister
6758 timeouts by the callback function.
6760 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Some "Incomplete WHOIS info" errors has been appearing on the
6763 log files. Took away the entry->userinfo check from WHOIS
6764 reply sending. The entry->userinfo is now " " if client did not
6765 provide one. I thought this was fixed earlier but something
6766 is wrong still. Let's see if the error still appears.
6768 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Fixed a minor bug in the login when the channel key is
6771 re-generated in the server. It used to generate the key in
6772 wrong order and thus caused problems in the channel traffic.
6774 * Fixed a minor bug in channel key distsribution after
6775 KICK command. The key was not sent to the router even though
6778 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added silc_ske_process_key_material_data as generic routine
6781 to process any key material as the SILC protocol dictates. The
6782 function is used by the actual SKE library but can be used by
6783 applications as well. This relates to the private message keys
6784 and the channel private keys since they must be processed the
6785 same way the normal SILC session keys. The protocol dictates
6786 this. Affected files: lib/silcske/silcske.[ch].
6788 Added also silc_ske_free_key_material to free the
6789 SilcSKEKeyMaterial structure.
6791 * Defined silc_cipher_set_key function to set the key for
6792 cipher without using the object's method function. The affected
6793 files: lib/silccrypt/silccipher.[ch].
6795 * Implemented silc silc_client_add_private_message_key,
6796 silc_client_add_private_message_key_ske,
6797 silc_client_del_private_message_key,
6798 silc_client_list_private_message_keys and
6799 silc_client_free_private_message_keys functions in the
6802 Added functions silc_client_send_private_message_key to send
6803 the Private Message Key payload and silc_client_private_message_key
6804 to handle incoming Private Message Key payload.
6806 * Added Cipher field to the Private Message Key payload to set
6807 the cipher to be used. If ignored, the default cipher defined
6808 in the SILC protocol (aes-256-cbc) is used.
6810 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Removed lib/silcclient/ops.h file.
6814 Redefined parts of the SILC Client Library API. Created new
6815 file silcapi.h that deprecates the ops.h file and defines the
6816 published Client Library API. Defined also private message key
6817 API and channel private key API into the file.
6819 This is the file that the application must include from the
6820 SILC Client Library. Other files need not be included by
6821 the application anymore.
6823 * Added new key_agreement client operation callback and also
6824 defined the Key Agreement library API for the application.
6826 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6829 is used by clients to request key negotiation between another
6830 client in the SILC network. If the negotiation is started it
6831 is performed using the SKE protocol. The result of the
6832 negotiation, the secret key material, can be used for example
6833 as private message key.
6835 Implemented the Key Agreement payload into the files
6836 lib/silccore/silauth.[ch].
6838 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Redefined ciphers for the SILC protocol. Added some new ciphers
6841 and defined the key lengths for the algorithms. Changed the
6842 code accordingly. The default key length is now 256 bits.
6844 * Fixed SKE key distribution function silc_ske_process_key_material
6845 when the key length is more than 128 bits. The default key
6846 length in SILC is now 256 bits.
6848 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6849 to indicate unsupported algorithm.
6851 * Renamed rijndael.c to aes.c and all functions as well.
6853 * Fixed a long standing channel key setting bug in client library.
6854 Weird that it has never surfaced before.
6856 * Fixed bug in channel deletion. If the entire channel is removed
6857 then it must also delete the references of the channel entry
6858 from the client's channel list as the client's channel entry and
6859 the channel's client entry share same memory.
6861 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Implemented CONNECT and SHUTDOWN commands in the client.
6865 * Implemented CLOSE command to the client.
6867 * Added the function silc_idlist_find_server_by_name into the
6868 files silcd/idlist.[ch].
6870 Added the function silc_idlist_find_server_by_conn into the
6871 files silcd/idlist.[ch].
6873 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * DIE command was renamed to SHUTDOWN. Updated the both code
6878 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6879 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6881 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6884 * Added function silc_server_create_connection function to create
6885 connection to remote router. My server implementation actually
6886 does not allow router to connect to normal server (it expects
6887 that normal server always initiates the connection to the router)
6888 so the CONNECT command is only good for connecting to another
6891 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6894 or some other client was kicked from the channel.
6896 Implemented the handling of the notify type to both client
6899 Implemented silc_server_send_notify_kicked to send the KICKED
6900 notify. It is used to send it to the server's primary router.
6902 * Implemented the KICK command into server and client.
6904 * Added `query' argument to the silc_idlist_get_client function
6905 to indicate whether to query the client from server or not if
6908 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6909 to indicate that the client is not channel founder.
6913 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Removed the rng context from SilcPacketContext structure and
6916 changed that the packet routine uses the Global RNG API.
6918 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Added support for quit message that client can "leave" on the
6921 channel when it quits the SILC. It is ditributed inside the
6922 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6924 Added silc_server_free_client_data that will take the
6925 signoff message as argument.
6927 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6929 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Updated parts of the protocol specification to keep it up
6934 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6937 payloads in one packet.
6939 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6940 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6941 use now the new List flag.
6943 * Also deprecated the following packet types: REPLACE_ID,
6944 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6946 * Added list support for Notify packet in server.
6948 * Added silc_server_send_notify_channel_change to send the
6949 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6950 the silc_server_send_replace_id.
6952 * Added silc_server_send_notify_nick_change to send the
6953 NICK_CHANGE notify type. Deprecates the function
6954 silc_server_send_replace_id.
6956 * Added silc_server_send_notify_join to send the JOIN notify type.
6957 Deprecates the function silc_server_send_new_channel_user.
6959 * Added silc_server_send_notify_leave to send LEAVE notify type.
6960 Deprecates the function silc_server_send_remove_channel_user.
6962 * Added silc_server_send_notify_cmode and
6963 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6964 types. Deprecates the silc_server_send_set_mode function.
6966 * Added SERVER_SIGNOFF notify type to indicate that server has
6967 quit. This means that all clients on the channel from that
6968 server will drop. This can be also used when netsplit happens.
6970 Deprecated REMOVE_ID packet type since it is not needed anymore
6973 Added silc_server_send_notify_server_signoff to send the
6974 SERVER_SIGNOFF notify type. Deprecates the function
6975 silc_server_send_remove_id.
6977 Added also silc_server_send_notify_signoff to send the
6978 SIGNOFF notify type.
6980 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6981 SILC protocol from this day on. Changed the protocol
6982 specification as well.
6984 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6985 notify type. It is used between routers to notify about
6986 topic changes on a channel.
6988 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6991 * Partly updated the protocol specification to comply with the
6992 changes now made. It is still though a bit outdated.
6994 * The JOIN notify type now takes one extra argument <Channel ID>.
6995 The packet used to be destined to the channel but now the
6996 JOIN type may be sent as list thus it is impossible to
6997 destine it to any specific channel. By adding this argument
6998 it is again possible.
7000 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7002 * Added CREDITS file. The CHANGES and CREDITS file will appear
7003 in the distribution as well.
7005 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7008 types in the server's silcd/packet_receive.c.
7010 * Implemented CMODE and CUMODE to work in router environment.
7012 * Fixed minor encoding and decoding buglet from the
7013 lib/silccore/silcmode.c.
7015 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7018 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7020 * Changed all SilcConfigServer* and silc_config_server* to
7021 SilcServerConfig* and silc_server_config*, respectively.
7024 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Associated the ID (client or server ID) to the Authentication
7027 Payload to avoid any possibility of forging. Updated the
7028 protocol specification and the code accordingly.
7030 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * The RSA key length is now save to the RsaKey context in the
7033 key generation process in lib/silccrypt/rsa.c. The key length
7034 is now used to figure out the maximum size of the block allowed
7035 to be encrypted/signed.
7037 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7038 is equivalent to the silc_mp_mp2bin but does not allocate any
7041 * Changed silc_mp_mp2bin API to take length argument. If it is
7042 non-zero then the buffer is allocated that large. If zero, then
7043 the size is approximated using silc_mp_sizeinbase, which however
7046 * Created Global RNG API which is global RNG that application can
7047 initialize. After initializing, any routine anywhere in the
7048 code (including library) can use RNG without allocating a new
7049 RNG object. This was done to allow this sort of use of the
7050 RNG in code that has no chance to allocate RNG object. All
7051 applications currently allocate this and many routines in the
7052 library use this. Affected file lib/silccrypt/silcrng.[ch].
7054 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7055 it to use the Global RNG API.
7057 * Defined Authentication Payload into protocol specification that
7058 is used during SILC session to authenticate entities. It is
7059 used for example by client to authenticate itself to the server
7060 to obtain server operator privileges.
7062 Implemented this payload into the lib/silccore/silcauth.[ch].
7063 Implemented also routines for public key based authentication
7064 as the new protocol specification dictates.
7066 Moved definitions of different authentication methods from
7067 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7069 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7070 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7071 silc_pkcs_verify_with_hash functions into the file
7072 lib/silccrypt/silcpkcs.[ch].
7074 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * The client entry's userinfo pointer must be always valid.
7077 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7078 will fail since it requires the userinfo. Now, the userinfo
7079 is allocated as "" if actual userinfo does not exist. Actually,
7080 it must exist and it is totally Ok to drop client connections
7081 that does not announce the userinfo. However, we will make
7082 this workaround for now.
7084 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7085 to return the remote port by socket.
7087 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7090 SILC_SERVER_PENDING_EXEC and added an new macro
7091 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7092 data or when error occurs while processing the pending command.
7094 Added new argument `destructor' into silc_server_command_pending
7095 and to the SilcServerCommandPending object. This destructor is
7096 now called after calling the pending callback or if error occurs
7097 immediately. If error occurs the actual pending callback won't
7098 be called at all - only the destructor. The destructor may be
7099 NULL if destructor is not needed.
7101 All this applies for client library code as well. Similar
7102 changes were made there as well for the pending commands.
7104 In the client, the application must now allocate the
7105 SilcClientCommandContext with the silc_client_command_alloc
7108 * Added reference counter to the SilcServerCommandContext. Added
7109 function silc_server_command_alloc and silc_server_command_dup
7112 Same type of functions added to the client library for the same
7115 * Removed the cmd_ident from IDListData away since it is now
7116 global for all connections. It is the command identifier used
7117 in command sending and with pending commands. The affected file
7120 * Added reference counter to the SilcSocketConnection objecet to
7121 indicate the usage count of the object. The object won't be
7122 freed untill the reference counter hits zero. Currently only
7123 server uses this, and client ignores it. The client must be
7124 set to use this too later. The affected files are
7125 lib/silccore/silcsockconn.[ch]. Added also the function
7126 silc_socket_dup to increase the reference counter.
7128 This was mainly added because it is possible that the socket
7129 is removed underneath of pending command or other async
7130 operation. Now it won't be free'd and proper DISCONNECTING
7131 flags, etc. can be set to avoid sending data to connection that
7132 is not valid anymore.
7134 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7135 the connection. After that it sets SILC_SET_DISCONNECTED.
7136 It is, however, possible that the socket data is not still freed.
7137 The silc_server_packet_process now checks that data is not
7138 read or written to connection that is DISCONNECTED. The socket
7139 get's freed when the reference counter hits zero.
7141 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Changed the client operation API: channel_message operation's
7144 `sender' is now the client entry of the sender, not the nickname
7145 and the `channel' is the channel entry, not the channel name.
7147 In the private_message operation the `sender' is now also the
7148 client entry of the sender not the nickname.
7150 Affected file is lib/silcclient/ops.h and all applications
7151 using the client operations.
7153 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Moved the calling of ops->connect() from connect_to_server_final
7156 into receive_new_id functin since that is the point when the
7157 client is actually allowed to send traffic to network. The
7158 affected file is lib/silcclient/client.c.
7160 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7163 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7164 (if needs broadcasting) instead of broadcasting the packets one
7165 by one which would make a burst in the network traffic.
7167 * Added `broadcast' argument to the functions in silcd/server.[ch]
7168 silc_server_create_new_channel[_with_id] to indicate whether
7169 to send New Channel packet to primary router.
7171 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Added new function into the silcd/server.[ch] files:
7174 silc_server_create_new_channel_with_id to create new channel with
7175 already existing Channel ID.
7177 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7178 lib/silccore/silcpacket.h. This packet is used t send list of
7179 Set Mode payloads inside one packet. Server uses this to set
7180 the modes for the channels and clients on those channels, that it
7181 announced to the router when it connected to it. The protocol
7182 specification has been updated accordingly.
7184 * The silc_server_new_channel did not handle the packet coming
7185 from normal server as it normally does not send that. However,
7186 when it announces its channels it does send it. Implemented
7187 the support for that.
7189 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7190 into the file lib/silccore/id.h.
7192 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Fixed memory leaks in the functions silc_idlist_del_client,
7195 silc_idlist_del_channel and silc_idlist_del_server in the file
7196 silcd/idlist.c. All of those leaked like a sieve.
7198 * Fixed some small memory leaks in the client's function
7199 silc_client_notify_by_server.
7201 * Added functions into silcd/server.c: silc_server_announce_clients,
7202 silc_server_announce_channels and silc_server_announce_server.
7203 These functions are used by normal and router server to announce
7204 to its primary router about clients, channels and servers (when
7205 router) that we own. This is done after we've connected to the
7208 These functions effectively implements the following packet types:
7209 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7210 and SILC_PACKET_NEW_ID_LIST.
7212 * Added new functions into the silcd/packet_receive.[ch]:
7213 silc_server_new_id_list, silc_server_new_channel_list and
7214 silc_server_new_channel_user_list to handle the incoming
7215 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7217 * Added support of changing Channel ID in the function
7218 silc_server_replace_id. If the server that announces a channel
7219 to the router already exists in the router (with same name but
7220 with different Channel ID), router is responsible to send
7221 Replace ID packet to the server and force the server to change
7222 the Channel ID to the one router has.
7224 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7225 client that the Channel ID has been changed by the router. The
7226 normal server sends this to the client. Client must start using
7227 the new Channel ID as the channel's ID.
7229 Implemented handling of this new type into lib/silcclient/client.c
7230 into the function silc_client_notify_by_server.
7232 * Added new function silc_idlist_replace_channel_id into the files
7233 silcd/idlist.[ch] to replace the Channel ID.
7235 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Call silc_server_command_identify_check always when processing
7238 the IDENTIFY command in silcd/command.c
7240 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7243 send keepalive packets. The packet can be sent by clients,
7244 servers and routers.
7246 Added function silc_socket_set_heartbeat into the file
7247 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7248 If not set, the heartbeat is not performed. The actual
7249 heartbeat is implemented in the low level socket connection
7250 library. However, application is responsible of actually
7253 Added silc_server_send_heartbeat to send the actual heartbeat
7254 packet into silcd/packet_send.[ch]. Server now performs
7255 keepalive with all connections.
7257 * Added silc_task_get_first function into lib/silcutil/silctask.c
7258 to return the timeout task with shortest timeout. There was a bug
7259 in task unregistration that caused problems. TODO has been
7260 updated to include that task system must be rewritten.
7262 * The client library will now resolve the client information when
7263 receiving JOIN notify from server for client that we know but
7264 have incomplete information.
7266 * Rewrote parts of silc_server_remove_from_channels and
7267 silc_server_remove_from_one_channel as they did not remove the
7268 channel in some circumstances even though they should've.
7270 * Encryption problem encountered in server:
7272 The LEAVE command used to send the Channel Key packet to the
7273 router immediately after generating it. However, the code
7274 had earlier sent Remove Channel user packet but not immediately,
7275 ie. it was put to queue. The order of packets in the router
7276 was that Channel Key packet was first and Remove Channel User
7277 packet was second, even though they were encrypted in the
7278 reverse order. For this reason, MAC check failed. Now, this
7279 is fixed by not sending the Channel Key packet immediately but
7280 putting it to queue. However, this is more fundamental problem:
7281 packets that are in queue should actually not be encrypted
7282 because packets that are sent immediately gets encrypted
7283 actually with wrong IV (and thus MAC check fails). So, packets
7284 that are in queue should be encrypted when they are sent to
7285 the wire and not when they put to the queue.
7287 However, the problem is that the current system has not been
7288 designed to work that way. Instead, the packet is encrypted
7289 as soon as possible and left to the queue. The queue is then
7290 just purged into wire. There won't be any fixes for this
7291 any time soon. So, the current semantic for packet sending
7294 o If you send packet to remote host and do not force the send
7295 (the packet will be in queue) then all subsequent packets to the
7296 same remote host must also be put to the queue. Only after the
7297 queue has been purged is it safe again to force the packet
7300 o If you send all packets immediately then it safe to send
7301 any of subsequent packets through the queue, however, after
7302 the first packet is put to queue then any subsequent packets
7303 must also be put to the queue.
7305 Follow these rules and everything works fine.
7307 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Added new function silc_server_remove_clients_by_server to
7310 remove all client entries from ID list when the server connection
7311 is lost. In this case it is also important to invalidate all
7312 client entires as they hold the invalid server entry. This
7313 fixes fatal bug when server has lost connection and will reconnect
7316 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7318 * Made some sanity checks to silc_server_daemonise like to check
7319 whether the requested user and group actually exists.
7321 * Added sanity check to SKE's silc_ske_responder_finish to check
7322 that the public and private key actually is valid.
7324 * Invalidate the client's nickname when receiving Replace ID
7325 packet and the Client ID is being replaced. This means that the
7326 server will query the nickname if someone needs it (client)
7329 * Sort the ID Cache in client library when the ID Cache data
7330 has changed (needs sorting).
7332 * Do not allow for SILC client to create several connections to
7333 several servers. The client does not support windows right now
7334 and generating multiple connections causes weird behaviour.
7336 Irssi-silc client does support windows and can handle several
7337 connections without problems, see: www.irssi.org and SILC plugin.
7339 * Fixed some places where client was added to the IDList. The
7340 rule of thumb is following (in order to get everything right):
7341 If the client is directly connected local client then the
7342 `connection' argument must be set and `router' argument must be
7343 NULL to silc_idlist_add_client function. If the client is not
7344 directly connected client then the `router' argument must
7345 bet set and the `connection' argument must be NULL to the
7346 silc_idlist_add_client function.
7348 * The funtion silc_server_packet_send_local_channel actually did
7349 not check whether the client was locally connected or not. It
7350 does that now. Fixed a bug related to LEAVE command.
7352 * Fixed Remove Channel User payload parsing bug in server's
7353 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7355 * The server's silc_server_save_channel_key now checks also the
7356 global ID list for the channel as it might not be in the local
7357 list. Fixed a bug related to LEAVE command.
7359 * Is this the end of the [<unknown>] buglet that has been lurking
7360 around for a long time? A little for loop fix in server's
7361 silc_server_command_whois_parse that is used by both IDENTIFY
7362 and WHOIS command. At least, this was a clear bug and a cause
7363 of one type of [<unknown>] buglet.
7365 * WHOIS and IDENTIFY commands call the function
7366 silc_server_command_[whois/identify]_check function even if
7367 we are not router server.
7369 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Added --with-gmp configuration option. If set the GMP
7372 is always compiled in the SILC source tree. If not set then
7373 it is checked whether the system has the GMP3 installed. If
7374 it has then the GMP won't be compiled (the system's headers
7375 and library is used), if it doesn't have it then the GMP is
7376 compiled in the SILC source tree.
7378 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Changed RSA private exponent generation to what PKCS #1
7381 suggests. We try to find the smallest possible d by doing
7382 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7383 not security fix but optimization.
7385 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Added new config entry [Identity] to fork the server and run
7388 it as specific user and group. A patch from Bostik.
7390 * Imported Dotconf configuration library into lib/dotconf.
7391 This will be used to create the SILC configuration files later.
7392 It will appear in the distsribution after this commit.
7394 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * A big code auditing weekend happening. Auditing code for
7397 obvious mistakes, bugs and errors. Also, removing any code
7400 Removed files for being obsolete:
7402 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7403 inline in the file lib/silcutil/silcbuffer.h)
7405 o lib/silcutil/silcbufutil.c (the header has inline versions)
7407 Changed code to fix possible error conditions:
7409 o The buffer formatting routines now check that the destination
7410 buffer really has enough space to add the data. This applies for
7411 both buffer formatting and unformatting
7412 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7413 unformatting was changed to accomodate following rules:
7414 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7415 sent to the function while XXX_*STRING will not allocate or copy
7416 the data into the buffer. Instead it sets the pointer from the
7417 buffer into the pointer sent as argument (XXX_*STRING used to
7418 require that the pointer must be allocated already). This change
7419 makes this whole thing a bit more consistent and more optimized
7420 (note that the data returned in the unformatting with XXX_*STRING
7421 must not be freed now). The routines return now -1 on error.
7423 o Tried to find all code that use buffer_format and buffer_unformat
7424 and added return value checking to prevent formatting and
7425 especially unformatting errors and possible subsequent fatal
7428 o Changed ske->x and ske->KEY to mallocated pointers in
7429 lib/silcske/silcske.h. Fixed possible data and memory leak.
7431 o Added return value checking to all *_parse* functions. Fixed
7432 many memory leaks as well.
7434 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7435 so that buffer overflows would not happen. All code now also
7436 checks the return value as it can fail.
7438 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Added reconnection support to server if the normal server looses
7441 its connection to the router (for example if router is rebooted).
7442 The server performs normal reconnection strategy implemented
7443 to the server. Affected file silcd/server.c.
7445 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Added new packet type SILC_PACKET_SET_MODE that is used to
7448 distribute the information about changed modes (for clients,
7449 channels and clients channel modes) to all routers in the
7450 network. Updated the protocol specification accordingly.
7452 Added functions into silcd/packet_send.c and
7453 silcd/packet_receive.c: silc_server_send_set_mode,
7454 silc_server_set_mode.
7456 Added new files silcmode.[ch] into lib/silccore that implements
7457 the encoding and decoding of Set Mode Payload. Added new type
7458 SilcSetModePayload. Moved the definitions of different modes
7459 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7461 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7463 * Oops, a little mistake in server's connection authentication
7464 protocol. The protocol is not ended with FAILURE but with
7465 SUCCESS if the authentication is Ok. :) Affected file is
7468 * Implemented NICK_CHANGE notify handling in server in the file
7469 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7470 the local clients on the channel. After the changing nickname
7471 in router environment snhould work and the [<unknown>] nickname
7472 should appear no more.
7474 The silc_server_replace_id function that receives the Replace ID
7475 payload now sends the NICK_CHANGE notify type also in the file
7476 silcd/packet_receive.c
7478 * Changed WHOIS and IDENTIFY command to support the maximum amount
7479 of arguments defined in protocol specs (3328 arguments). This
7480 fixed a bug that caused problems when there were more than three
7483 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Added extra parameter, command identifier, to the
7486 silc_client_send_command so that explicit command identifier
7489 Changed that ID list routines uses specific command identifier
7490 when sending WHOIS/IDENTIFY requests to the server so that they
7491 can be identified when the reply comes back.
7493 Affected files lib/silcclient/command.[ch],
7494 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7496 * Added `sender' argument to silc_server_packet_send_to_channel
7497 to indicaet the sender who originally sent the packet to us
7498 that we are now re-sending. Ignored if NULL. Affected file
7499 silcd/packet_send.[ch].
7501 * Added some server statistics support in silcd/server_internal.h
7502 SilcServerStatistics structure and around the server code. Also
7503 send some nice statistics information when client is connecting
7506 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Fixed channel ID decoding in server's JOIN command reply in
7509 silcd/command_reply.c
7511 * Fixed braodcasting of replace ID payload to not to send it if
7512 we are standalone server in silcd/packet_receive.c.
7514 * Fixed all channel message sending routines to not to send
7515 packets to clients that has router set, since they are routed
7516 separately in the same function earlier. Affects file
7517 silcd/packet_send.c and all channel packet sending functions.
7519 * In USERS reply, res_argv[i] are not allocated, the table
7520 is allocated. Thus changed that free the table, not its
7523 * In server's whois_check and identify_check if the client is
7524 locally connected do not send any WHOIS commands - they are not
7527 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7529 * Fixed some minor bugs in client when sending WHOIS command. The
7530 arguments was in wrong order.
7532 * Removed statis function add_to_channel from server in
7533 silcd/command.c that was previously used with the joining but
7536 * Tested USERS command in router environment successfully with two
7537 routers, two servers and two clients.
7539 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Reorganized the USERS command and command reply in client library
7542 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7543 When the command is given by user we register a pending command
7544 callback that will reprocess the command after the reply has been
7545 received from the server. When reprocessing the packet we then
7546 display the information. Thus, the USERS information is displayed
7547 now in the command callback instead of in the command reply
7548 callback. The processing of the command is same as previously
7549 when server has sent the command reply in the JOINing process.
7551 * Added to USERS command in silcd/command_reply.c to join the client,
7552 we didn't use to know about, to the channel after we've created
7553 a client entry for it. Also, for clienet we did know already still
7554 check whether it is on the channel or not and add it if not.
7556 * Removed silc_server_command_join_notify as the function and its
7559 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Changed the client's pending command handling to the same as the
7562 server's pending command handling. It is also now possible to
7563 execute command reply functions from other command reply
7564 function as the function callbacks for commands and command
7565 replies are one and same. The pending commands are not static
7566 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7567 in client connection context. Thus, pending commands are server
7568 connection specific as it is convenient.
7570 Changed the function silc_client_command_pending and
7571 silc_client_command_pending_del and added new function
7572 silc_client_command_pending_check. Removed the
7573 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7576 * Added cmd_ident, current command identifier, to the client
7577 connection context in lib/silcclient/client.h to keep track on
7578 command identifiers used in command sending. Client's command reply
7579 function handling now supports the mandatory command identifiers.
7581 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7582 funtions in client to fully support pending command callbacks.
7584 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7585 as one of the arguments to the application in the command reply
7588 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7589 before first releasing SILC but came back. Now it is removed again
7590 and should come back nomore. The FORWARDED flag was used only
7591 by the JOINing procedure by forwarding the command packet to router.
7592 Now, the JOINing procedure has been changed to more generic (due
7593 to various router environment issues) and FORWARDED is not needed
7594 anymore for anything. The protocol specification is yet to be
7597 Now, removed silc_server_packet_forward from server and the flag
7598 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7600 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Renamed NAMES command to USERS command. The NAMES was named that
7603 due to historical reasons. Now it is renamed. Also, rewrote
7604 parts of the USERS command. The nickname list is not sent anymore
7605 by the server. Only Client ID and mode lists are sent in the USERS
7606 command. Changed this also to the protocol specification.
7608 The client now resolves the names and stuff after it receives
7609 the USERS list from the server when joining to the channel.
7611 * WHOIS and IDENTIFY commands has been changed to support multiple
7612 Client ID's per command. One can now search for multiple users
7613 in the network by sending only one WHOIS or IDENTIFY command.
7614 Changed the code and the protocol specifications.
7616 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7617 uses silc_server_command_whois_parse to parse the request. */
7619 * If normal server, do not parse the WHOIS and IDENTIFY requests
7620 before sending it to the router. Saves some time.
7622 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Fixed JOIN command on client library. Wrong number of arguments
7625 used to crash the client.
7627 * Added silc_server_channel_has_global function to check whether
7628 channel has global users or not.
7630 * Added silc_server_channel_has_local function to check whether channel
7631 has locally connected clients on the channel.
7633 * The silc_server_remove_from_one_channel now checks whether the
7634 channel has global users or not after given client was removed from
7635 the channel. It also checks whether the channel has local clients
7636 on the channel anymore. If it does not have then the channel entry
7637 is removed as it is not needed anymore.
7639 * The silc_server_notify now checks on JOIN notify whether the joining
7640 client is one of locally connected or global. If it is global then
7641 the channel has now global users on the channel and that is marked
7642 to the channel entry. Also, it now saves the global client to
7643 global list who is joining and JOINs it to the channel. This is
7644 for normal server, that is.
7646 Changed silc_server_send_notify_on_channel,
7647 silc_server_packet_relay_to_channel and
7648 silc_server_packet_send_to_channel check if we are normal server
7649 and client has router set (ie. global client) do not send the
7650 message to that client, as it is already routed to our router.
7652 * Implemented LEAVE notify type handling in silc_server_notify
7655 * Tested LEAVE command in router environment successfully. Tested
7656 with two routers, two servers and two clients.
7660 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7662 * Implemented SIGNOFF notify type handling in silc_server_notify
7665 * silc_server_remove_id now removes the client entry from all channels
7666 it has joined and thusly sends SIGNOFF notify type.
7668 * Rewrote the NAMES list generation in server by removing two excess
7669 loops. The lists are created now inside one loop.
7671 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * silc_server_remove_channel_user checks now also global list
7674 for channel and client.
7676 * silc_server_new_channel_user checks now both local and global
7677 list for channel and client. Fixed a bug in client id decoding.
7678 Used to decode wrong buffer.
7680 * silc_server_channel_message checks now both local and global
7681 list for channel entry.
7683 * Tested channel joining (hence JOIN) in router environment
7684 successfully. Tested with two routers, two servers and two
7687 * Tested channel message sending in router environment successfully.
7689 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Added silc_server_save_channel_key into server.[ch] to save the
7692 received channel key in Channel Key payload processing. It is
7693 also used in JOIN command reply handling.
7695 Equivalent function silc_client_save_channel_key added into
7696 client.[ch] into client library.
7698 * Changed JOIN command reply to send information whether the channel
7699 was created or not (is existing already) and the channel key
7700 payload. Changed protocol specs accordingly.
7702 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7703 the request was sent by ID and not by nickname. Crashed on
7706 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7708 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7709 now correctly save the received data.
7711 * silc_server_free_sock_user_data now notifies routers in the
7712 network about entities leaving the network.
7714 At the same time implemented functions silc_server_remove_id
7715 and silc_server_send_remove_id to receive and send REMOVE_ID
7716 packets. The packet is used to notify routers in the network
7717 about leaving entities. The ID removed will become invalid in
7720 * Added function silc_idlist_del_server into server. Removes and
7721 free's server entry from ID list.
7723 * silc_server_private_message function now checks, if we are router,
7724 that the destination ID really is valid ID, naturally.
7726 * In router when NEW_ID packet is received (for new client) the
7727 hash of the Client ID is saved in the ID Cache but the
7728 client->nickname is set to NULL, instead of putting the hash
7731 IDENTIFY command now also checks that client->nickname must be
7732 valid. If it is not if will request the data from the server who
7733 owns the client. Added new function
7734 silc_server_command_identify_check.
7736 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7737 to set the command to already allocated Command Payload.
7739 * Tested private message sending in router environment with two
7740 routers, two servers and two clients. Fixed minor bugs and now
7743 * Fixed segfault from client's NAMES command. Used to crash if
7746 * Forwarded packets must not be routed even if it is not destined
7747 to the receiver. Changed server code comply with this.
7749 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7751 * Added `require_reverse_mapping' boolean value to ServerParams
7752 structure. If TRUE (not default) the server will require that
7753 the connecting host has fully qualified domain name.
7755 If the reverse mapping is not required and hostname could not be
7756 found the IP address is used as hostname.
7758 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Implemented version string checking to both client and server.
7761 The check is incomplete currently due to the abnormal version
7762 strings used in development version of SILC.
7764 * Changed all command functions in server to use the new
7767 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7769 * Changed char *data to unsigned char *data in ID Cache system to
7770 support binary data as ID Cache data. Changed code to support
7771 binary data in lib/silccore/idcache.c.
7773 * Renamed silc_server_packet_relay_command_reply to
7774 silc_server_command_reply as it is normal packet receiving
7775 function. Rewrote the function to accept command replys for
7776 servers and not only for clients.
7778 * Mark remote router always as registered server if we are connecting
7779 to it. Otherwise, commands sent by the router to us are ignored.
7781 * All ID List find routines now returns the ID Cache Entry pointer
7782 as well if requested.
7784 * WHOIS command works now in router environment, tested with two
7785 routers, two servers and two clients.
7787 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7788 in router environment (as it is almost equivalent to WHOIS) but
7789 hasn't been tested thoroughly. Added new functions:
7791 silc_server_command_identify_parse
7792 silc_server_command_identify_send_reply
7793 silc_server_command_identify_from_client
7794 silc_server_command_identify_from_server
7796 * Disabled route cache adding because adding two different ID's with
7797 same IP replaces the old cache entry thus giving wrong route.
7798 The entry->router->connection is always the fastest route anyway
7799 so route cache may not be needed. Of course, new routes maybe
7800 established after receiving the ID when the entry->router->connection
7801 might not be anymore the most optimal.
7803 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7805 * Add route cache for received ID for fast routing.
7807 * Added silc_server_packet_route to route received packet on router
7808 that is not destined to us.
7810 * Renamed silc_server_get_route to silc_server_route_get.
7812 * Added id_string and id_string_len fields into SilcServer to
7813 include encoded ServerID for fast comparing without excess
7814 encoding of the ID's.
7816 * Cleaned up WHOIS command on server side. Added following static
7819 silc_server_command_whois_parse
7820 silc_server_command_whois_check
7821 silc_server_command_whois_send_reply
7822 silc_server_command_whois_from_client
7823 silc_server_command_whois_from_server
7825 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7826 arguments in command replies. All command functions should be
7827 updated to use this macro.
7829 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7831 * Minor typo fixes on command reply handling on server.
7833 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Added silc_server_command_add_to_channel internal routine to add
7836 the client to the channel after router has created the channel and
7837 sent command reply to the server.
7839 * Added generic silc_server_send_command to send any command from
7842 * Use static buffer with ID rendering instead of duplicating data.
7844 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * Fixed a channel user mode bug when joining to a channel server gave
7847 everybody channel founder rights, oops.
7849 * We mark ourselves as the router of the incoming server connection
7850 if we are router ourselves. This way we can check in some packet
7851 sending functions whether it is locally connected server. For
7852 incoming router connections we put NULL.
7854 * For router sending packets locally means now always sending the
7855 packet cell wide; to local clients and local servers. For normal
7856 server sending packet locally means sending it to only local
7859 * Fixed the JOIN command to really work in router environment. If the
7860 channel is created it is always created by the router. Router is
7861 also responsible of making the initial joining to the channel,
7862 sending JOIN notify to the sending server and distributing
7863 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7864 does not exist server doesn't do anything else but forward the
7865 command to the router which performs everything.
7867 * Added silc_server_send_channel_key function to send the Channel Key
7870 * Added silc_server_create_channel_key to create new channel key. The
7871 channel key is now re-generated everytime someone joins or leaves
7872 a channel, as protocol dictates. Note: channel->key_len is the
7875 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7878 packet_receive.[ch] to separate packet sending and receiving
7879 routines. The server.[ch] now includes everything else including
7880 actual packet processing (writing and reading data) and other
7883 Renamed silc_server_private_message_send_internal to
7884 silc_server_send_private_message. The routine is still though
7885 used only to relay private messages as server does not send
7886 private messages itself.
7888 Renamed silc_server_new_channel to silc_server_create_new_channel
7889 and added new function sicl_server_new_channel that handles the
7890 incoming New Channel packet. Added also new sending function
7891 silc_server_send_new_channel to send New Channel Payload.
7893 * Added new function silc_server_notify to process incoming notify
7894 packet to the server/router. Server may then relay the notify
7895 to clients if needed.
7897 * Added new function silc_server_new_channel_user to process incoming
7898 New Channel User packet. Router will redistribute the packet and
7899 send JOIN notify to its local clients and locally connected servers
7900 if needed. Normal server will send JOIN notify to its local client
7901 on same channel when received this packet. Added also corresponding
7902 sending function silc_server_send_new_channel_user to sent the
7905 * Added boolean route argument to send_notif_to_channel and
7906 packet_send_to_channel functions to attempt to route the packet
7907 if it is TRUE and send only locally if it is FALSE.
7909 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7911 * silc_server_replace_id now broadcasts the received replace ID
7912 packet if it is not broadcast packet already. The router must
7913 broadcast to inform other routers about changed ID.
7915 * Added backpointer to server's router into SilcServer context in
7916 silcd/server_internal.h.
7918 * Fixed silc_server_packet_broadcast to send correct broadcast
7921 * The channel key is now distributed to the local client as soon
7922 as it is received from the router (in router environment) so that
7923 no other packet may be sent for the channel until client has
7926 * silc_server_remove_channel_user now broadcasts the received
7927 Remove Channel User packet if it is not broadcast packet already.
7928 The router must broadcast to inform other routers about removed
7931 * Added users field into SilcPacketContext that is a reference count
7932 of the context. One can increase the reference count by calling
7933 silc_packet_context_dup which is now changed to just increase the
7934 reference count instead of duplicating the data. The reference
7935 count is decresed by calling silc_packet_context_free that will
7936 free the data after the reference count hits zero.
7938 For now on the packet context and everything allocated into it
7939 (including the raw packet from network) must be freed by calling
7940 the new silc_packet_context_free function. Added also new function
7941 silc_packet_context_alloc that must be used now to allocate the
7942 context. This also means that if a routine is asynchronous from
7943 silc_[client/server]_packet_parse_type the packet context must
7944 be duplicated by calling silc_packet_context_dup. Otherwise it
7945 gets free'd after silc_[client/server]_packet_parse_type returns.
7946 Also, one must remember that if packet is duplicated then its
7947 reference count must be decresed by calling the free function as
7948 many times as it was duplicated.
7950 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7951 from both client and server.
7953 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7955 * Made joining to a channel working in router environment.
7957 * Cleaned up JOIN command on server side and create function
7958 silc_server_command_join_channel internal routine to make the
7961 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Changed silc_command_pending list to SilcDList. Also, added
7964 `ident' field to SilcServerCommandPending structure to identify
7965 the reply and to call correct callback.
7967 Added silc_server_command_pending_check function to replace the
7968 corresnponding macro. The silc_command_pending list is not
7971 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7972 to set identifier to previously allocated Command Payload. It
7973 is used to set identifier for command when resending Command
7976 * Added silc_command_payload_encode_payload to encode Command
7977 Payload buffer from SilcCommandPayload structure.
7979 * Added silc_argument_payload_encode_payload to encode Argument
7980 payload buffer from SilcArgumentPayload structure.
7982 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7984 * Changed WHOIS command to support router connection on server side.
7985 The whois request is always sent to router unless the server is
7986 standalone server. After server has received the reply from the
7987 router will it send the reply to the client.
7989 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7990 broadcast received broadcast packet. The function is used only
7991 by router. The broadcast packet is always sent to the router's
7994 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7995 render given ID to printable string, for log files for example.
7997 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Made basic router to router connections working. At least they
8000 can now connect to each other but nothing really works the way
8001 they are supposed - yet.
8003 * Added new initiator token to RouterConnection configuration
8004 file in silcd/serverconfig.[ch]. It is used to tell whether we
8005 are the initiator to the remote router or whether we'll expect
8006 the other end to connect.
8008 * Moved registering of listener task to silc_server_init, hence
8009 the server starts listenning as soon as it is run, even if it
8010 does not have connections to other routers. Let's see how well
8013 * Changed default connection retry timeouts for more suitable in
8016 * Removed cipher and such arguments from silc_idlist_add_client
8017 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8018 Added new function silc_idlist_add_data to add the keys and stuff
8021 * Added SilcIDListData structure and added it to SilcClientEntry
8022 and SilcServerEntry as their first field in the structure. This
8023 way we can explicitly cast the ID entries to the SilcIDListData
8024 structure and get common data for the entries. In past, we had
8025 to first check what type of connection it is and then cast it to
8026 correct ID entry type. Now, we can directly cast the opaque
8027 pointer to the SilcIDListData (no matter what ID entry it actually
8028 is) and get the data needed.
8030 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8032 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8033 in some circumstances even if threre were timeout tasks, though not
8034 IO tasks, but tasks anyway. Now fixed.
8036 * Defined SilcServerConnection structure to hold connection specific
8037 stuff about directly connected servers and routers. The definition
8038 is currently in silcd/server_internal.h. I thought about having
8039 a bit more important role fro this struct but for now it is used
8040 only when connecting to other server (or router actually).
8042 * Added connecting retry support in server when connecting to
8043 router(s). The retry feature implement exponential backoff
8044 algorithm. Also, added SilcServerParams structure to hold default
8045 parameters for server. For now, it include these retry settings
8046 and are hard coded. After server is moded to be as Silc Server
8047 Library this structure will be more important.
8049 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * Changed client librarys channel->clients table to SilcList and
8052 changed code accordingly.
8054 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Changed client's channel table to SilcList and changed code
8057 accordingly. Also changed SilcChannelClientEntry to include back-
8058 pointer to the channel so that client entry can use that structure
8059 as list as well and we have fast cross-reference to the channel.
8060 This change dramatically decreased the complexity of channel
8061 handling with client entry and vice versa (removed one extra
8062 loop when searching for channel entry from many functions).
8064 * Changed server->sim from table to SilcDList and changed code
8067 * NAMES command can now be used from user interface. It will show
8068 the user list on the channel, neatly.
8070 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8071 Code now saves realname of the user if it becomes available.
8073 * Renamed configure.in to configure.in.pre and made ./prepare
8074 script to automatically add correct version string to
8075 configure.in which it creates from configure.in.pre.
8077 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8079 * NAMES command reply now shows users mode with the nickname when
8082 * Moved silc_client_ch[u]mode[_char] functions from
8083 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8084 place sucks, they are utility functions and should be in some
8087 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8089 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8092 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Added TRQ (efficient deque and list library) into lib/trq. This is
8097 a very good list library that is currently used in the SILC. Defined
8098 SilcList API over the library because I didn't like the API very
8099 much. See lib/trq/silclist.h for the API and examples of how to
8100 use the API. Fixed various places in the code to use the new
8101 SilcList API. The SilcList is meant for lists that has a structure
8102 already defined as a list. It is not suitable to add just some
8103 context to the list (in TRQ, the context is the list actually).
8105 So, I defined SilcDList that can be used for the purpose where
8106 predefined list structure does not exit. This can be used as
8107 such list. Now some context just can be added to the SilcDList.
8108 Currently this list is not used in the SILC just yet, though there
8109 are a lot places where this can replace dynamically allocated
8110 tables and I will fix these places, later, to use SilcDList.
8111 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8112 and use TRQ internally).
8114 Also fixed some annoying warning messages that the original TRQ
8115 code generated. Also minor changes to TRQ's Makefile.in.
8117 * Added support for querying by Client ID to both WHOIS and
8118 IDENTIFY commands into server, as required by the protocol.
8120 * Removed method function pointers from SilcBuffer structure. They
8121 weren't used to anything and just increased the context size for
8122 no good reason. This change also made silc_buffer_alloc and
8123 silc_buffer_free functions inline functions.
8125 * Disabled command flooding detection support until it's fixed so
8126 that it accepts commands in but does not execute them more than once
8129 * Added silc_net_localhost(), to return local hostname, into
8130 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8131 that must be initialized before calling silc_client_init.
8133 * Added new function: silc_server_send_notify_on_channels to send
8134 notify messages to all channels client has joined. It is assured
8135 that the message is sent only once per client.
8137 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8138 lib/silcutil/silcutil.[ch] as silc_format function. The new
8139 function is generic and is used by server as well, not only by
8140 the logging routines.
8142 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8143 the provided version string was not acceptable. Added new function:
8144 silc_ske_check_version into lib/silcske/silcske.h. The function
8145 must be implemented by the application (client or server) and it
8146 does not reside in the SKE library. The function checks the version
8147 string remote end sent.
8149 * Added back pointers (to opaque context and to SilcSocketConnection)
8150 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8152 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8153 duplicate packet context structure.
8155 * Changed `notify' client operation to send same arguments as client
8156 receives from server except for ID's. ID's are mapped to correct
8157 ID entry and that is returned. Also, if channel entry is not sent
8158 by server but the notify is for channel the channel entry is sent
8159 to application (otherwise application doesn't know that it is for
8160 channel (library gets it from packet's Destination ID)).
8162 * Added silc_client_remove_from_channels into client library to
8163 remove a client from all channels it has joined to. Used when
8164 received SIGNOFF notify from server. Added also new function
8165 silc_client_replace_from_channels to replace old ID entry with
8166 new ID entry on all channels. Used when received NICK_CHANGE
8169 * Fixed ID Cache list handling in silc_idlist_get_client in
8170 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8171 to get (or query) client by ID.
8173 * Updated TODO list.
8175 * Added connection authentication status message defined by the
8176 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8177 support for these into the code in client and server side.
8179 * Added generic function silc_client_send_command to send any command
8180 with variable argument list. Application should use this function
8181 to send commands if the command functions provided by the library
8182 does not suite for the application's user interface needs.
8184 * Added new `failure' client operation. Application is notified about
8185 received failure packet if client is executing a protocol. In this
8186 case the protocol's execution has failed.
8188 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8189 is required by the protocol.
8191 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8192 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8195 * Added status flag to SilcSKE object to indicate realtime status
8196 of the SKE protocol.
8198 * Application receives now exactly same command reply arguments as
8199 the library receives from server. However, if ID is received the
8200 corresponding ID entry is returned to the application (eg. Client
8201 ID is mapped to correct SilcClientEntry entry and that is returned).
8202 Changed command_reply client operation due to this change.
8204 * Changed all ID's in commands and in command replys as ID Payloads.
8205 Change affected both client and server side codes.
8207 All ID's sent in SILC network (with execption of ID's in SILC
8208 Packet header) are sent in ID Payload to support variable length
8211 * Server now notifies nick changes and notifies all clients on
8212 the channels about the new nickname (about the new Client ID,
8215 * Implemented CMODE command to change channel modes. Supports all
8216 channel modes defined by the protocol specs except ban and invite
8217 lists. (Also, private channel key mode is supported but support for
8218 setting private channel key in client is missing, thus, this mode
8219 has no effect on client side (except that server requires that the
8220 client uses private channel key and normal channel traffic does not
8223 Also, invite mode works per se, but INVITE command does not work
8224 yet correctly, so you can set channel as invite only channel but
8225 inviting clients to the channel does not work (it is yet to be
8226 thought what's the best way to do it).
8228 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8229 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8230 Implemented CUMODE command to change user's mode on the channel.
8231 Supports all modes defined by the protocol specs.
8233 * Added NAMES command reply to return users modes on the channel.
8235 * Removed unnecessary and slow ciphers from lib/silccrypt.
8237 * Set SO_KEEPALIVE option to connection sockets by default.
8239 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8241 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8242 redefined the Notify Payload into protocol specs.
8244 * Added silc_id_payload_parse_id to get ID directly from raw
8247 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8249 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8250 accept searching by Client ID as well.
8252 * Added support for LEAVE and SIGNOFF notify types in client library.
8254 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8255 to parse ID Payload from raw data.
8257 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Added flags parameter into silc_ske_assemble_security_properties
8260 function in lib/silcske/silcske.[ch].
8262 * Changed notify client operation to fit better for notify messages
8263 sent by server. The notify payload received from server is now
8264 passed to the application (after parsing it to SilcNotifyPayload).
8265 It is application's responsibility to retrieve the arguments
8266 from the payload and show the message the way it wants. The message
8267 sent by server is implementation specific.
8269 * Changed public keys to comply with the protocol specification.
8270 Old public keys are not supported anymore and are not compatible.
8272 * Removed nickname from Channel Payload as the latest draft removed
8273 it. The client must resolve the nickname from the NAMES command
8274 reply received when it joined the channel.
8276 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8278 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Fixed some errors in protocol specification drafts.
8282 * Created lib/silccore/silcnotify.c to implement Notify Payload
8283 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8284 generic payloads described by protocol specifications. The file
8285 includes implementations for ID Payload and Argument Payload.
8287 * Changed Command Payload implementation to use the new Argument
8288 Payload. Changed command_xxxx_payload to command_payload_xxxx
8289 to comply with SILC coding conventions.
8291 * Added suppport for Argument Payload handling in Notify Payload
8292 implementation as protocol requires it. Added the new support
8293 into server and client lib as well.
8295 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8297 * Added support for multiple nicknames on same channel. [n] is
8298 added locally to the nickname if there are more than one same
8299 nicknames on the channel.
8301 * Server now sends all nicknames that matched WHOIS request.
8302 Client also shows the list received from server.
8304 * Added TOPIC command to client side. User can now set and show
8305 current topic on channel.
8307 * Added MOTD command to client and server. Also, server sends the
8308 motd when client connects to the server.
8310 * Changed version strings to comply ISO 8601.
8312 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8314 * Fixed protocol error handling in client library. It should now
8315 cope even if the SKE fails for some reason.
8317 * Made new protocol specification drafts for submitting to IETF.
8319 * Implemented TOPIC command to server in silcd/command.c.
8321 * Added two new notify types into lib/silccore/silcnotify.h:
8322 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8323 notify nickname change and topic setting/change on a channel.
8325 * API change of command_reply operation in client library. The
8326 application gets now the status type received from server as well.
8328 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8332 * Cras fixed and optimized the packet handling even further and
8333 it should work now. Minor change to the prototype of function
8334 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8336 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Added new function into lib/silcutil/silcschedule.[ch]:
8339 silc_schedule_with_fd to select() a specified fd. The function
8340 returns after timeout expires or data arrives or goes. The
8341 function is used by packet routines to wait that all data is
8342 received from network.
8344 * Fixed data reading from network in lib/silccore/silcpacket.c.
8345 The code now assures that all data is read from the fd and then
8346 continues packet processing. This was a bug fix since the code
8347 used to drop some data in some circumstances.
8349 * Added new function into lib/silcclient/client.[ch]:
8350 silc_client_start_key_exchange to start key exchange after
8351 connection has been established to server. The code internally
8352 now uses this funtion but its main purpose was to provide it
8353 for applications that perform their own connecting. After
8354 application has created a connection it merely calls this
8355 function to start the key exchange between client and server.
8356 The library takes care of everything else after that.
8358 Updated also lib/silcclient/README to explain the usage of
8361 * Do not send to application information that connection has
8362 been established. Application gets notified it by connect
8365 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8367 * Applied cras's patch to add silc_schedule_one function. The
8368 function runs scheduler once and returns.
8370 * Fixed the scheduler after cras messed it up. The timeout
8371 handling works now as it's supposed to work.
8373 * Added into lib/silccore/ silcnotify.h to include notify
8374 message types support. Changed silc_server_send_notify*
8375 functions, in server.[ch], to support those new notify types.
8376 Added the support for the notify types into client library,
8377 as well. Added new notify client operation into ops.h in
8380 * Changed silc_server_packet_send_to_channel to send normal
8381 packets instead of just channel message packets. The function
8382 is now used to send the notify packets to channels. It is not
8383 used to send channel message packets anymore, as server never
8386 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8387 va_arg()s as it seems to require it nowadays. I guess, if SILC
8388 is compiled with older va_arg() the new code should work anyway.
8390 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8392 * Splitted core library. Core library (lib/silccore) includes
8393 now only SILC protocol specific core (and common) components.
8394 Created new utility library (lib/silcutil) that includes more
8395 generic purpose stuff. The stuff for util library was taken
8396 from the old core library. This was minor and easy split.
8398 * Created SILC Client Library (lib/silcclient) that includes
8399 implementation of the SILC client without user interface. This
8400 was major move from silc/ directory. The code has been changed
8401 so that it is transparent towards the user interface. The
8402 silc/ directory includes now the same user interface as before
8403 and it uses the new client library. Read lib/silcclient/README.
8404 Basicly, the client library performs everything else related
8405 to SILC except user interface handling. Also, configuration
8406 files are considered to be part of user interface and library
8407 does not handle them.
8409 This change also changed a lot of structures, function naming etc.
8410 Most important change was that SilcClientWindow object was
8411 renamed to SilcClientConnection in the client library. Created
8412 also new file lib/silcclient/ops.h. Also added new files
8413 silc/local_command.[ch] and silc/client_ops.[ch].
8415 All these changes were made to make it easier for user interface
8416 designers to create what ever user interface for the SILC client
8419 It is also expected that the server will be moved to lib
8420 directory as well and SILC Server Library will be created;
8421 sometimes in the future.
8423 * Removed Local commands from lib/silccore/silccommand.h as
8424 they are application specific and new client library does not
8425 handle any of those anymore.
8427 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8428 old client implementation in silc/.
8430 * Added support for callback functions in SILC_LOG_* macros.
8431 Application can now set its own callbacks that will be called
8432 instead of using the default functions that will always print
8433 the debug messages to stderr (or stdout). Also, debugging can
8434 now be disabled by setting silc_debug to FALSE and re-enabled by
8435 setting it to TRUE. Note, that logging will still work even
8436 if debugging is disabled.
8438 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8439 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8440 silc_log_reset_debug_callbacks.
8442 * To enable debugging in silc client one must give now -d
8443 option on command line.
8445 * Changed silc_schedule_init to automatically allocate task queues
8446 if they are not allocated before calling it.
8448 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8450 * Added GMP 3.1 into math library.
8452 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8455 a channel in SILC network. The packet is used by servers and
8456 routers to notify other routers that user has left a channel.
8457 This little feature was missing until now. Added the feature
8458 to protocol specification as well.
8460 Added functions: silc_server_send_remove_channel_user and
8461 silc_server_remove_channel_user into server.[ch].
8463 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8464 lib/silccore/silcpacket.h. However, they are not implemented
8467 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8469 * Fixed joining to a channel and sending channel messages
8470 between server and router. The channel message sending should
8471 now work inside a cell.
8473 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8475 * Fixed the private message sending between server and router.
8476 The private message sending should now work inside a cell.
8478 * Added silc_server_replace_id into server.[ch] to replace
8479 existing ID in the SILC network.
8481 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8482 and silc_idlist_replace_server_id into idlist.[ch] in server.
8484 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8486 * Fixed the server to server connections. Server can again now
8487 connect to router. Router to router connections probably does
8490 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8492 * Added dynamic protocol registering support. Now protocols can
8493 registered and unregistered on the fly. Patch by cras.
8495 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8497 * Added lib/contrib directory to hold routines that some platforms
8498 don't have but are needed by SILC.
8500 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8501 into lin/contrib to provide getopt() and getopt_long() for
8502 those who don't have it.
8504 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Added AWAY command to client. When away message is set and
8507 client receives a private message packet the client automatically
8508 replies to the sender with the away message.
8510 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8511 bug seemed to be the cause of recent problems when compiling
8514 * Added version detection support to SKE protocol specification
8515 and added the new changes to the SKE implementation as well.
8516 There were other minor changes in the SKE protocol as well.
8518 Many changes in lib/silcske/silcske.[ch] and in
8519 lib/silcske/payload.[ch].
8521 * Added ^U functionality, clear input line. Patch from cras.
8523 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8525 * Mainly small bugfixes on core library. Fixed some debugging
8526 logging and buffer overflow in silclog.c.
8528 * Updated config.sub and config.guess on the distribution tree.
8530 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8532 * Added command lagging support in server. Client may execute
8533 commands now only once in two seconds.
8535 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8537 * Optimized packet reception. MAC computation and checking is now
8538 also more optimized. A lot previously duplicated code is now
8539 used as generic by both client and server.
8541 * Fixed key pair generation in clientutil.c
8543 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8545 * Added into lib/silccore/silcbufutil.[ch] new function;
8546 silc_buffer_realloc.
8548 * Moved generic packet sending/encryption functions to
8549 lib/silccore/silcpacket.[ch] from client and server. Some
8550 rewriting of the functions.
8552 * Moved all generic packet reception/decryption functions to
8553 lib/silccore/silcpacket.[ch] from client and server. The
8554 packet processing is now much cleaner in both client and server.
8555 These were major changes in both client and server.
8557 * Created many common functions in server to do packet sending.
8558 Previously code were duplicated a lot, this has been removed
8561 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8563 * Rewrote major parts of the ID cache system. Don't know
8564 whether it is better now or not but at least the API is more
8567 * Major rewrite on ID cache stuff on client because of the ID
8568 cache API changes. Added idlist.c to client.
8570 * Also major rewrite on ID cache stuff on server as well.
8571 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8572 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8573 in hand, instead they are all put into the ID cache system now.
8574 All server_idlist_* routines uses ID cache now instead of
8575 traversing its own lists (those lists does not exist anymore).
8576 SilcIDList though still exists. Also, SilcXXXEntry's are
8579 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Finally made the SKE implementation compliant to the protocol
8582 specification. All mp integers are now binary encoded as
8583 opposed being HEX encoded.
8585 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8588 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8589 functions: silc_[encode/decode]_pem. Also added function
8590 silc_encode_pem_file to PEM encode with newlines ('\n') for
8593 * SILC public keys are now encoded either PEM or binary. Same
8594 option is for private keys as well. By default private keys
8595 are binary encoded and public keys PEM encoded. Silly HEX
8596 encoding were removed.
8598 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8599 function to create fingerprints.
8601 * Fixed a bug in SHA1; does not change the original data anymore.
8603 * Partly implemented INFO command on client and server side.
8604 Fixed CLEAR command. Changes to SERVER command; show current
8605 server(s) when giving command without arguments. Added
8606 VERSION command to client.
8608 * Added check to server that unregistered connections cannot
8609 execute commands (unless it is specificly allowed).
8611 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8613 * Fixed screen refresh.
8615 * Fixed channel joining bug from client. On some circumstances
8616 client tried to join to a channel it had already joined.
8618 * Added public key verification process into client's protocol.c.
8619 The client now verifies the public key from user and saves
8620 it into ~./silc/serverkeys/ directory.
8622 Added into: clientutil.[ch]: silc_client_verify_server_key.
8624 * Changed SKE protocol's silc_ske_initiator_finish function
8625 to accept callback function that verifies the received public
8626 key. Removed old silc_ske_verify_public_key function.
8628 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8630 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8631 silc_pkcs_private_key[_data]_set.
8633 * Made the password and public authentication more cleaner in
8634 server's protocol.c.
8636 * Removed historic and obsolete protocol `channel_auth' from
8637 both client and server.
8639 * Removed wrong way of sending command status messages from
8640 server to client in server's command.c. The old way violated
8641 protocol specification.
8643 Changes to silccore/silccommand.[ch]: removed
8644 silc_command_encode_status_payload -> not needed anymore,
8645 changed silc_command_encode_payload_va to accept extra
8646 argument on variable argument list. The argument type must
8647 now be provided to the function. Also, added new function:
8648 silc_command_encode_reply_payload_va which is same as
8649 normal command_encode_payload_va except command status type
8650 is provided as extra argument.
8652 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8654 * Added ~./silc directory handling. The directory includes the
8655 public and private keys for the client.
8657 Added silc_client_check_silc_dir, silc_client_create_identifier
8658 and silc_client_load_keys.
8660 * Implemented SILC protocol compliant public key. Added public
8661 and private key saving to and loading from files.
8663 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8664 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8665 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8666 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8667 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8669 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8670 silc_pkcs_load_[public/private]_key.
8672 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8674 * Added silc_server_get_route (route.[ch]) to get connection
8675 data for the fastest route for given ID.
8677 * Implemented INVITE command on client and server. The command
8678 were re-defined in the SILC Protocol Specification and the
8679 implementation now complies with the specification.
8681 * Implemented PING command on client and server.
8683 * Implemented NAMES command on client and server. The server side
8684 supports currently only normal server not router server yet.
8685 Some changes to NAMES definition in SILC protocol specification.
8687 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8689 * Implemented LEAVE command on client and server.
8691 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8692 again. This change was made to the protocol as well. Server
8693 should not violate the protocol specification anymore.
8695 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8697 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8698 was tested. SOCKS4 was not but should work anyway.
