542 * Fixed a bug in library where sending a bogus authentication
543 payload would lead to a crash. Affected file is
544 lib/silccore/silcauth.c.
546 Sat Apr 13 13:09:24 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
548 * Added detach_disabled and detach_timeout server config
549 options to the server. Affected files silcd/serverconfig.[ch],
550 silcd/command.c and silcd/packet_receive.c.
552 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
554 * Added resolve_cmd_ident field to the SilcClientEntry structure
555 too so that if the entry is for example being resolved so
556 another command may attach to the same pending command reply
557 without requiring to resolve the same entry again. Added
558 support for adding multiple pending commands for one
559 command idenfier. Affected files lib/silcclient/command.[ch],
560 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
562 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
564 * Defined that server receives WHOIS command reply for private
565 and secret channels too. Updated protocol specs and the
566 code in server. Affected file silcd/command.c.
568 * Defined <channel user mode list> argument to WHOIS command
569 reply for returning user modes on the channels. The
570 channel list now doesn't include the user mode anymore but the
571 actual channel mode. Updated protocol specs and the code in
572 client and server. Affected files are silcd/command_reply.c,
573 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
574 and lib/silcclient/command_reply.c.
576 * Save the channels list in WHOIS command reply in normal server
577 so that WHOIS always shows joined channels also in normal
578 server and not just on router. Affected file is
579 silcd/command_reply.c.
581 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

584 and secret channels too. Updated protocol specs and the
585 code in server. Affected file silcd/command.c.
587 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
589 * Changed the UMODE's mode mask argument to be optional. If
590 not provided then the command merely returns the current mode
591 mask to the client. Updated protocol specs and the server.
592 Affected file is silcd/command.c.
594 * Added SILC session detachment/resuming support. It is possible
595 to detach by closing the network connection and then re-connect
596 and resume to the old client session. Added DETACHED user
597 mode that server will set for detached client. Added new
598 packet RESUME_CLIENT which is used to perform the resuming
599 process. Added DETACH command. Updated the protocol specs,
600 core library, client and server. Protocol TODO #22. Very
601 many affected files around the tree.
603 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
605 * Changed the CMODE's mode mask argument to be optional. If
606 not provided then the command merely returns the current mode
607 mask to the client. Updated protocol specs and the server.
608 Affected file is silcd/command.c.
610 * Changed the Killer's Client ID in KILLED notify to be just
611 any ID payload since router server is allowed to kill as well.
612 Updated protocol specs, client libary and server. Affected
613 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
614 and irssi/src/silc/core/client_ops.c.
616 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
618 * Added new user modes ANONYMOUS for special anonymous servers
619 that may set the mode for client, and BLOCK_PRIVMSG which
620 client may set to block incoming private messages unless the
621 Private Message Key flag is set (using private keys to protect
622 private messages). Updated protocol specs and code in client
623 and server and core library. Protocol TODO #23. Affected
624 files are lib/silccore/silcmode.h, silcd/server.[ch],
625 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
626 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
628 * Added new channel user mode BLOCK_MESSAGES which the client
629 may set to itself to tell server not send channel messages.
630 Other packets such as channel key packets are still sent.
631 Protocol TODO #23. Updated the protocol specs, client and
632 server. Affected files are lib/silccore/silcmode.h,
633 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
634 lib/silcutil/silcutil.c, silcd/command.c, and
637 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Redefined the Status Payload to include now two 8 bit fields,
640 instead of one 16 bit field. This now makes it possible to
641 send list of errors. Updated the protocol specs and the code
642 in core library, client library and server. Protocol TODO #1.
643 Affected files are lib/silccore/silccommand.[ch],
644 lib/silcclient/command_reply.[ch], silcd/command.c,
645 silcd/command_reply.c and silcd/packet_receive.[ch].
647 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
649 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
650 must be handled by the application and should tell the application
651 that an error message was already printed, and it should print the
652 config coords (line, filename, ...). Affected files are
653 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
655 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
656 server config parsing code more readable.
658 Fixed a bug in the fetch_logging() config callback.
660 Affected files is silcd/serverconfig.c.
662 * Drop root privileges when started in foreground. Don't drop them
663 if debugging also. Affected file is silcd/silcd.c.

668 for setting various presence information. Added new modes:
669 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
670 specs and code. Protocol TODO #19. Affected files are
671 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
672 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
674 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
676 * Added STATS command to the protocol after all, to return
677 various statistical information about the network. It can
678 be used by clients to retrieve statistical information, and
679 servers may use it to to fetch cell and network wide
680 statistics from router. Updated the protocol specs and
681 implemented it to the server. Protocol TODO #16.
682 Affected files are lib/silccore/silccommand, silcd/command.[ch],
683 silcd/command_reply.[ch].
685 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
687 * The LIST command reply in client libary now adds new channel
688 entry if the returned channel doesn't exist yet in cache,
689 and returns the channel entry to the application in the
690 command_reply client operation. Affected file is
691 lib/silcclient/command_reply.c.
693 * Changed the channel message payload's MAC generation to
694 include the IV in the MAC as well. This way all relevant
695 parts of the channel message payload are authenticated also
696 with the channel message MAC (and not only by packet MAC).
697 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
698 Affected file is lib/silccore/silcchannel.c.
700 * Fixed the SKE to save the remote version, since the
701 silc_ske_parse_version mistakenly checked wrong version,
702 after it replaced the start payload. Affected files are
703 lib/silcske/silcske.[ch].
705 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
707 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
708 string utility functions. Added there also new functions
709 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
710 Affected files lib/silcutil/silcstrutil.[ch].
712 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
713 files are lib/silcutil/silcstrutil.[ch].
715 * Defined that the security property fields in SKE SHOULD be
716 UTF-8 encoded, defined that version string MUST be US-ASCII
717 encoded, defined that passphrases sent in connection
718 authentication protocol MUST be UTF-8 encoded. Implemented
719 these to the client and server. Defined also that other
720 passphrases sent in the protocol MUST be UTF-8 encoded.
721 Affected files are lib/silcske/silcske.c,
722 lib/silcclient/protocol.c, silcd/protocol.c,
723 silcd/serverconfig.c, and lib/silccore/silcauth.c.
725 * Changed the silc_client_close_connection interface to not
726 need the SilcSocketConnection which should not be visible
727 to application. Affected files are lib/silcclient/client.c
728 and lib/silcclient/silcclient.h.
730 * Rewrote the text for Private Message Key Payload in the
731 protocol specification. Protocol TODO #11.
733 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Upgraded the protocol version to 1.1, updated protocol specs
738 * Added the nickname as new argument to NICK_CHANGE notify and
739 added it to protocol specs and implemented it to client and
740 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
741 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
742 lib/silcclient/client_notify.c.

745 it to protocol specs and implemented it to client and server.
746 Protocol TODO #13. Affected files are silcd/command.c,
747 silcd/packet_receive.c, packet_send.[ch],
748 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
749 The killer's client entry is now returned to application in
750 the `notify' client operation.
752 * Fixed the Max Argument fields that had too large value set
753 in the protocol specs. Protocol TODO #14.
755 * Added the LEAVE command reply to return the ID of parted
756 channel. Updated protocol specs and implemented it to the
757 client and server. Protocol TODO #15. Affected files are
758 silcd/command.c, lib/silcclient/command_reply.c. The channel
759 entry is now returned to application in the `command_reply'
762 * Rewrote the version SKE version checking in client libary
763 and in server to use the silc_parse_version_string. Affected
764 files are lib/silcclient/protocol.c, silcd/protocol.c.
766 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
767 commands that was missing it, and updated protocol specs and
768 the server implementation. Protocol TODO #10. The affected
769 file is silcd/command.c.
771 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
772 generic reply to a generic request (REQUEST flag), and
773 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
774 way. A draft-riikonen-silc-flags-payloads-00.txt is written
775 to define the payload for DATA flag. Added the flags to
776 the implementation. Protocol TODO #9. Affected file is
777 lib/silccore/silcchannel.h.
779 Changed the client library to return the message length
780 to application as well in the channel_message and private_message
781 client operations. Affected files are
782 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
783 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
784 and lib/silcclient/client_ops_example.c.
786 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
787 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
788 the channel. Updated protocol specs and impelemented this
789 to client and server. Protocol TODO #6. Affected files are
790 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

793 Added new options m and M to CMODE command in Irssi SILC
794 client to set these modes.
796 * Deprecated all administrative commands from SILC protocol
797 since they are highly implementation specific commands.
798 Updated protocol specs. Moved the old commands in
799 implementations to private range of command types. Affected
800 files are silcd/command.c, lib/silcclient/command.c and
801 lib/silcclient/command_reply.c. Protocol TODO #8.
803 * Fixed a bug in server where sending unknown command crashes
804 the server. Affected file silcd/command.c.
806 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Added SILC_PROTOCOLVERSION macro to check protocol version
809 of a socket connection. The affected file is
810 lib/silcutil/silcsockconn.h.
812 * Added better error logging in rekey protocol. Affected file
815 * Do not check public key types in SKE during rekey. Affected
816 file lib/silcske/payload.c.
818 * Fixed the rekey protocol with PFS, which was totally broken.
819 Affected file silcd/protocol.c.
821 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
823 * Some client implementations quit network by doing first LEAVE
824 and then immediately SIGNOFF (like Bombyx). We now do check
825 after a short time after LEAVE notify and check whether the
826 client is still valid after LEAVE, and if not we remove it from
827 cache. Affected file is lib/silcclient/client_notify.c.
829 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
831 * Merged version 1.1.4 of zlib. Even if it not currently in use,
832 it's good not to have security holes here.
834 * Fixed a negative refcount situtuation for the config context.
835 Affected file is silcd/serverconfig.c.
837 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
839 * ROBOdoc documented lib/silcutil/silcutil.h.
841 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Optimized even more the SilcPacketContext structure. Now
844 totally saved 16 bytes of memory per context after optimization.
845 Affected files are lib/silccore/silcpacket.[ch].
847 * Made strict checks for valid SILC IDs. Affected file is
848 lib/silccore/silcid.c.
850 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
852 * Changed the object argument for silc_cipher_register,
853 silc_hash_register, silc_hmac_register and silc_pkcs_register
854 to const. Affected files are lib/silccrypt/silccipher.[ch],
855 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
857 * Changed the silc_get_username and silc_get_real_name to
858 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
860 * Fixed the Irssi SILC Client to use the silc_get_username and
861 silc_get_real_name insted of glib routines since the glib
862 routines only corrupt stack. Fixes the Irssi SILC to work in
863 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
865 * Fixed the Irssi to not use g_get_home_dir since it crashes
866 or returns garbage on cygwin and corrupts stack. Added function
867 get_home_dir to Irssi routines. Affected files are
868 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
870 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Made some structure optimizations. SFTP memory FS MemFSEntry
873 entry structure. Optimized SilcTask structure. Optimized
874 SilcPacketContext structure.
876 Affected files lib/silcsftp/sftp_fs_memory.c,
877 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
879 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * And yet again reverted back the config thing since Johnny
882 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
885 * Fixed memory leaks from config object. Affected files are
886 silcd/serverconfig.[ch].
888 * Added support for adding new connections to the server in rehash.
889 After rehash they take effect.
891 Added support for changing the maximum allowed connections in
892 rehash. The number can grow but going smaller is not supported.
894 Added function silc_server_num_sockets_by_remote to the
895 silcd/server_util.[ch].
897 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
899 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
901 * Added preliminary checking during config parsing for a valid
902 public/private key and removed further checks in the code.
903 Affected files are silcd/serverconfig.[ch], server.c.
905 * Moved functions silc_server_drop() and silc_server_daemonise()
906 from server.c to silcd.c since they are stricly related to
907 the application activity.
909 * Reverted a small part of the automatic ref/unref since
910 it caused a double unref in some situations. Affected
911 files are silcd/silcd.[ch], server.c, serverconfig.c.
913 * Added some .cvsignore files in the lib directory.
915 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
917 * Fixed silc_net_gethostbyaddr to correctly resolve by
918 address. Affected file lib/silcutil/silcnet.c.
920 * Fixed the notify relaying to client. The HMAC to be used
921 with relayed packets ws wrong and caused decryption failure
922 at the client end. Affected file is silcd/packet_receive.c.
924 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Created new branch silc_protocol_1_0_branch.
928 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
930 * Changed the silc_server_config_* routines to be SilcServer
931 independent. They are now officially application specific code
932 and not part of generic server implementation. Affected files
933 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
935 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Added automatic referencing of config context in the
938 silc_server_config_alloc, and automatic unreferencing in the
939 silc_server_config_destroy. Affected files are
940 silcd/serverconfig.[ch], silcd/silcd.c.
942 * Fixed the silc_log_quick handling in the logging routines.
943 It didn't log quickly when it was TRUE. Affected file is
944 lib/silcutil/silclog.c. Also the flush delay was set even
945 if it was 0 in config file. Affected file is
946 silcd/serverconfig.c.
948 * Added support for changing key pair of the server in rehash.
949 Affected file silcd/server.c.
951 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
953 * Fixed the TOPIC_SET notify to not cras. It changed the topic
954 too early, before getting the channel entry. Affected file
955 is silcd/packet_receive.c.
957 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
959 * Added functions silc_server_config_[ref/unref], these are used
960 to prevent that the config object is destroyed.
962 No longer directly affect global variables silc_log_quick and
963 silc_log_delay, they are first cached inside the config object
964 and then applied with silc_server_config_setlogfiles().
966 silc_server_config_set_defaults() is now internal to
967 serverconfig.c, there are no reasons to show this internal stuff
970 Affected files are silcd/serverconfig.[ch].
972 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
973 fprintf's to stderr, since some code may be executed again after
974 the server went into the background. Affected files are
977 * Added rehash support. Added function silc_server_rehash() that
978 will perform all the basic tasks of the rehashing procedure.
980 * Added command line option `-x, --hexdump'. This will enable the
981 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
982 The option `--hexdump' implies `--debug'.
984 * Fixed a bad bug in the logging APIs (silcutil library) where
985 the application would crash after calling silc_log_reset_all().
987 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
989 * Fixed the KICKED notify handling in client library to
990 correctly remove the channel and all entries from the
991 channel when I was kicked. This bug crashed the client.
993 Fixed yet another but in KICKED notify handling to remove
994 the kicked client correctly from the channel.
996 Affected file is lib/silcclient/client_notify.c.
998 * Fixed a minor bug in looking up correct client entry
999 in KICKED notify in server. Affected file is
1000 silcd/packet_receive.c.
1002 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1003 sources correctly to distribution. Fixes --with-gmp option.
1005 * Removed the manual rehashing from ID Cache, and changed it
1006 to use the SILC Hash Table's auto rehash feature. Affected
1007 file is lib/silccore/silcidcache.c.
1009 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Fixed a bug in the silc_client_nickname_format function that
1012 handles the multiple same nickname formatting. Two clients
1013 with same nickname caused problems after the first one left
1014 and rejoined. It didn't format the nickname correctly.
1015 Affected file is lib/silcclient/idlist.c.
1017 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1019 * Don't change the topic if olod topic is same as new one.
1020 Affected file is silcd/packet_receive.c.
1022 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1024 * Added cross-reference support to the SILC Documentation
1025 generator. All types across all HTML files are now cross-
1026 referenced. Affected files util/robodoc/generator.c and
1027 scripts/silcdoc/silcdoc.
1029 * Added file lib/silcutil/silctypes.h to include all the
1030 arithmetic type definitions and some macros. Removed
1031 includes/bitmove.h and moved macros to silctypes.h.
1033 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1035 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1037 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1039 * Added `type' argument to silc_id_payload_parse_id function which
1040 now returns the type of the ID to the sent pointer. Affected
1041 file is lib/silccore/silcid.[ch].
1043 * Added check for CMODE_CHANGE notify type that mode change is
1044 allowed by the sender. Affected file silcd/packet_receive.c.
1046 * Added check for CUMODE_CHANGE notify type that mode change is
1047 allowed by the sender. Affected file silcd/packet_receive.c.
1048 Added the ID type as CUMODE_CHANGE notify type as argument
1049 to the `notify' client operation. Affected files are
1050 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1052 * Added function silc_client_add_server to the client library.
1053 Added support for resolving also channel and server info when
1054 received unknown entity in notify packet. Affected files are
1055 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1057 * Added function silc_command_get_status to return the command
1058 status from the command reply's argument payload. Affected files
1059 are lib/silccore/silccommand.[ch].
1061 * Added check for KICKED notify type that the kicking is
1062 allowed by the client. Affected file silcd/packet_receive.c.
1064 * Created function silc_get_input which can be used to get input
1065 (echo on or off) from user on command line. Affected files are
1066 lib/silcutil/silcutil.[ch].
1068 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Optimized silc_server_packet_relay_to_channel function.
1071 Added new function silc_channel_message_payload_encrypt which
1072 can be called directly if channel message payload needs to
1073 be encrypted and is already encoded (no need to call _encode
1074 function). Packet relaying is now done by router without any
1075 extra memory allocations. Affected files are
1076 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1077 silcd/packet_send.c.
1079 * Fixed the INVITE notify handling. It took wrong arguments
1080 as invite list and invite delete. Affected file is
1081 silcd/packet_receive.c.
1083 * Added check for TOPIC_SET notify type that the topic change is
1084 allowed by the client. Affected file silcd/packet_receive.c.
1086 * Added check for INVITE notify type that inviting is allowed by
1087 the client. Affected file silcd/packet_receive.c.
1089 * Changed the silc_server_client_on_channel to return the
1090 SilcChannelClientEntry as well. Moved the function
1091 silc_server_check_cmode_rights to server_util.[ch].
1092 Affected files are silcd/server_util.[ch], silcd/command.c.
1094 * Added function silc_server_check_umode_rights to check whether
1095 changing client's user mode is allowed. Added check for
1096 UMODE_CHANGE notify type that the umode change is allowed
1097 by the client. Affected files are silcd/server_util.[ch],
1098 silcd/packet_receive.c and silcd/command.c.
1100 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1102 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1103 ID length. It ignored that ID can be IPv6 based as well.
1104 Affected file lib/silccore/silcpacket.h.
1106 * Fixed the silc_id_id2str and silc_id_str2id to take the
1107 IPv6 address offset's into consideration. Affecte file is
1108 lib/silccore/silcid.c.
1110 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Fixed the internal Unix scheduler functions to check for
1113 NULL context they may receive. The affected file is
1114 lib/silcutil/unix/silcunixschedule.c.
1116 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1118 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1119 can specify different directory with --home command line
1120 parameter. Affected files irssi/src/silc/core/client_ops.c,
1123 * SILC-specific commands aren't now executed if the active server
1124 isn't of SILC-type, so there won't be problems with having
1125 IRC and SILC protocol support in same client. Affected files
1126 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1129 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1131 * Improved the signal support in SILC Schedule. Added new
1132 function silc_schedule_signal_call which is used by application
1133 to mark a signal to be called. It is now safe to perform
1134 any kind of tasks in signal callbacks since it is guaranteed
1135 that the application specified signal callback is called
1136 after the signal is over. Affected files are
1137 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1139 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added `name' field to SilcChannelPrivateKey to represent
1142 application given name for the key. Moved also the context from
1143 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1144 Added the `name' argument also to the function
1145 silc_client_add_channel_private_key.
1147 Added function silc_client_current_channel_private_key to set the
1148 current channel private key in use.
1150 Added "change" command to KEY command which can be used to change
1151 the current channel private key. Bound the command also to
1152 alt+K (Alt+Shift+k).
1154 Also affected files lib/silcclient/client_channel.c,
1155 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1157 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1159 * Added silc_rng_get_byte_fast function in to the
1160 lib/silccrypt/silcrng.[ch].
1162 * Changed the interface of silc_packet_assemble and the
1163 silc_packet_send_prepare. If silc_packet_assmble is now
1164 called the application does not call silc_packet_send_prepare
1165 because the library will call it automatically. These
1166 interfaces now also return a reference to the outgoing buffer
1167 which includes the assembled packet, which the application can
1168 use to encrypt the packet.
1170 Affected files are lib/silccore/silcpacket.[ch],
1171 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1172 silcd/packet_send.c, server_backup.c and packet_receive.c.
1174 * Fixed a packet sending bug on very high load, where outgoing
1175 packet queue wasn't handled correctly and packets got corrupted.
1176 Affected files are lib/silcutil/*/silc*sockconn.c,
1177 lib/silcclient/client.c and silcd/server.c.
1179 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1181 * Added macro SILC_PACKET_DATALEN which can be used during
1182 packet assembling to check whether the data to be added to
1183 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1184 len is truncated until it fits it.
1186 Added checks for maximum length of channel message payload and
1187 private message payload also.
1189 Added checks for maximum packet length in server and in
1192 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1193 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1194 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1195 lib/silcclient/client_prvmsg.c.
1197 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1199 * Added silc_server_packet_queue_purge call to the
1200 silc_server_disconnect_remote to assure that all data in the
1201 queue before disconnecting is sent to the network. Affected
1202 file silcd/server.c.
1204 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * Added the deleting of server's own ID cache entry to the
1207 silc_server_free function. Free also everything else that
1208 has been allocated in silc_server_init. The affected file
1211 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1213 * Added functions silc_parse_version_string, silc_version_to_num,
1214 and silc_ske_parse_version to parse SILC protocol style version
1215 strings. Affected files lib/silcutil/silcutil.[ch] and
1216 lib/silcske/silcske.[ch].
1218 * Added new configuration params: version_protocol, version_software
1219 and version_software_vendor to specify what version the remote
1220 host must at least be to be able to connect to server. The vendor
1221 string can be regex matched too. Added new function
1222 silc_server_connection_allowed to check maximum number of allowed
1223 connections, and allowed versions for incoming connections.
1224 Affected files are silcd/server.c, server_util.[ch] and
1227 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1229 * Added preliminary support for signals in scheduler. The
1230 signals we care about are now blocked always when the scheduler
1231 is locked. This way we can synchronise the use of signal with
1232 scheduler. It is guaranteed that when signal occurs the scheduler
1233 is not locked, and thus new tasks can be safely added to the
1236 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1237 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1238 Added new platform specific routines
1239 silc_schedule_internal_signals_[un]block and
1240 silc_schedule_internal_signal_[un]register.
1242 Added new functions to SILC Schedule API:
1243 silc_schedule_signal_[un]register. Each signal that application
1244 is going to use should be registered to the scheduler.
1246 Affected files are lib/silcutil/silcschedule.[ch],
1247 lib/silcutil/*/silc*schedule.c.
1249 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1251 * Check for unauthenticated client and server in the
1252 silc_server_new_client and silc_server_new_server functions.
1253 Affected file silcd/packet_receive.c.
1255 * Added function silc_string_is_ascii to check whether given
1256 string is 7-bit ASCII string. Affected files are
1257 lib/silcutil/silcutil.[ch].
1259 * Added function silc_id_is_valid_server_id into the
1260 silcd/serverid.c and added checking for valid Server ID's in
1261 silc_server_new_server. The Server ID must always be based
1262 on the server's public IP address.
1264 * Added logging of DISCONNECT packet message in the server.
1265 Affected file silcd/server.c.
1267 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1269 * Changed all library interfaces that use Global RNG to also
1270 accept SilcRng as argument. Affected files are
1271 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1272 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1273 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1274 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1275 lib/silccrypt/rsa.c.
1277 * Added function silc_pkcs_generate_key to the
1278 lib/silccrypt/silcpkcs.[ch] for applications so that they
1279 don't need to do pkcs->pkcs->init calls anymore.
1281 * Remove SilcSocketConnection from the SFTP API since it really
1282 wasn't needed there. The application has the information
1283 saved in its contexts anyway and the SFTP layer doesn't need
1284 know about it. Affected files lib/silcsft/silcsftp.h and
1285 lib/silcsftp/sftp_[server/client].c.
1287 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1288 The SilcSimContext is not SilcSim.
1290 * Fixed possible buffer overflows in silc_id_render in the
1291 lib/silcutil/silcutil.c.
1293 * On EPOC the global crypto module lists are not used at all
1294 in the crypto library. Added support for using the constant
1295 algorithm list on EPOC. Affected files are
1296 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1299 * Fixed the handling of third parameter of KICKED notify, since
1300 it was mistakenly updated to SILC Protocol 1.0 even though it
1301 is to be included in 1.1. Since it is not in 1.0 it is not
1302 mandatory, and this fix now handles it only if it is provided,
1303 and it is not error if it is not provided. Affected file
1304 lib/silcclient/client_notify.c.
1306 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1309 client. Affected file irssi/src/silc/core/client_ops.c.
1311 * Merged with Irssi 0.8.4 from irssi.org CVS.
1313 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1315 * Check for valid socket connection in client entries before
1316 sending any messages. Fixes a crash, but doesn't fix some
1317 other underlaying bug that is lurking there. Affected
1318 file silcd/packet_send.c.
1320 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1322 * $usermode, $cumode and $cumode_space expandos shouldn't do
1323 anything with non-SILC server records. Affected file
1324 irssi/src/silc/core/silc-expandos.c
1326 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1328 * Fixed the silc_net_check_[host/local]_by_sock to support
1329 IPv6 bound sockets as well. Now they can return IPv6 addresses
1330 as well. Affected file lib/silcutil/silcnet.c.
1332 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1333 Affected lib/silcutil/unix/silcunixnet.c.
1335 * Fixed ID rendering (at least on some platforms, not NetBSD)
1336 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1338 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1340 * Added silc_hash_public_key and silc_hash_public_key_compare
1341 functions to be used with SilcHashTable. They can be used to
1342 hash public keys and compare public keys in hash table. Affected
1343 file lib/silcutil/silcutil.[ch].
1345 * Added support for specifying multiple public keys for Client
1346 connection section in server configuration file. This makes it
1347 possible to accept multiple public keys from same host, or to
1348 make a section that accepts any incoming host, and have the
1349 accepted public keys listed in the section.
1351 Added functions silc_sever_[find/get]_public_key, added the
1352 support for this actually to all connection sections but only
1353 the Client section is currently allowed to specify multiple
1356 Affected files are silcd/server.c, server_internal.h,
1357 command.c, protocol.c, server_util.[ch], packet_receive.c.
1359 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Merged Irssi 0.8.2 from irssi.org CVS.
1363 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1365 * If silc_debug is TRUE, also output standard logging messages
1366 to stderr with the debug output.
1368 Made silc_log_reset_all() flushing all channels before returning.
1369 Also fixed some documentation typos.
1371 Affected files are lib/silcutil/silclog.[ch].
1373 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Fixed the server to check correctly the amount of connections
1376 from single host, by checking also the type of the connection.
1377 Fixed also the comparison of number of connections and number
1378 of allowed connections. Affected files are silcd/server.c,
1381 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1383 * Fixed the USERS command reply to save the user's mode on the
1384 channel as well. Fixed JOIN command reply to check whether a
1385 client is on channel already and not join it twice. Affected
1386 file lib/silcclient/command_reply.c.
1388 * Added new file silc-expandos.c into irssi/silc/core/ to return
1389 various stuff for various signal for the statusbar etc. updating.
1390 Now Irssi SILC client prints channel user modes etc. on the
1393 * The user mode (like server/router operator changes) is now shown
1394 on the Irssi SILC client's statusbar. The affected files are
1395 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1397 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1399 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1400 to SILC_SCHEDULE_[UN]LOCK macros.
1402 * Added more error printing to logs in server code. Affected
1403 files silcd/server.c and silcd/protocol.c.
1405 * Fixed -S option parsing in Irssi SILC Client. Affected file
1406 irssi/src/silc/core/silc-core.c.
1408 * Added silc_buffer_alloc_size function. Affected file is
1409 lib/silcutil/silcbuffer.h.
1411 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1414 constants. Affected files in
1415 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1418 * Changed the internal SFTP Memory FS table to const. Affected
1419 file lib/silcsftp/sftp_fs_memory.c.
1421 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1423 * Fixed the buffer formatting and unformatting routines to
1424 check the size of 64 bits types with sizeof(). Affected
1425 file is lib/silcutil/silcbuffmt.c.
1427 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1429 * Removed 0.6.x backwards support.
1431 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1433 * Changed all integer type names:
1434 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1435 to avoid collisions with other libraries using same type names
1438 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Added `prefer_ipv6' argument to the functions
1441 silc_net_gethostbyname[_async]. If it is TRUE it will return
1442 IPv6 address over IPv4. If FALSE IPv4 address is returned
1443 even if IPv6 address was found. Affected files
1444 lib/silcutil/silcnet.[ch].
1446 * Added support silc_net_create_connection[_async] to fallback
1447 to IPv4 address if IPv6 address could not be used (like if
1448 it doesn't work on a specific system). Affected file in
1449 lib/silcutil/unix/silcunixnet.c.
1451 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1453 * Added silc_schedule_reinit function to do the enlarging
1454 of the max tasks handling capabilities of the scheduler.
1455 Affected files lib/silcutil/silcschedule.[ch].
1457 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Added automatic extern "C" { ... } for C++ compilers so the
1460 application does not need to define them. Affected file
1461 includes/silcincludes.h.
1463 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1464 old name went against naming convention. Applications now
1465 include "silcclient.h" instead of "clientlibincludes.h".
1466 Removed includes/clientlibincludes.h, it is redundant now.
1468 * Renamed includes/version.h to silcversion.h.
1470 * Added really preliminary support for OS/2 into the util
1471 library. Only thread & mutex API is implemented, others
1472 are still to be implemented. Created the lib/silcutil/os2/
1473 directory. Created also file includes/silcos2.h.
1475 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1477 * Added preliminary BeOS support into the util library.
1478 Created lib/silcutil/beos/, and implemented all the needed
1479 functions to support SILC on BeOS. Created also file
1480 includes/silcbeos.h.
1482 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1484 * Added proper initializations to silc's irssi code, so it's
1485 now possible to load it as module. Affected files
1486 irssi/src/silc/core/silc-core.c,
1487 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1489 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1491 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1494 * Fixed the silcdoc document generator to correct generate
1495 docs from all kinds of filenames. Affected files are
1496 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1498 * ROBOdoc documented lib/silcutil/silcmemory.h.
1499 Added also new function silc_memdup.
1501 * Removed lib/silcutil/silcbufutil.h and moved those routines
1502 to the lib/silcutil/silcbuffer.h.
1504 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1506 * Added `user_count' to the SilcChannelEntry which now tells the
1507 number of users on the channel. The user count is now saved
1508 in normal server of global channels as well. Affected files
1509 silcd/server.c, idlist.h, packet_receive.c and command.c.
1511 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1512 include file utility functions.
1514 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1515 instead of calling directly OS routines.
1517 * Fixed NICK change printing in Irssi SILC Client. Fixed
1518 KICKED notify printing in Irssi SILC Client. Affected file
1519 irssi/src/silc/core/client_ops.c.
1521 * Fixed a NICK change bug in client library, to not recreate the
1522 client_entry->channels hash table everytime nick is changed.
1523 Affected file lib/silcclient/client.c.
1525 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1527 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1528 the SKE interface a bit.
1530 * Fixed padding problem in PKCS#1. The padding was not actually
1531 random since the random number generator was used incorrectly.
1532 This security bug affects only when encrypting with PKCS#1, and
1533 it is not currently used at all in SILC. SILC only use signing
1534 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1536 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1621 Added the configuration object to SilcServerConnection struct.
1622 Affected files silcd/server_internal.h, server.c.
1624 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1626 * Add the client on channel after it was resolved at the
1627 channel message receiving, and it was not already on the

1648 Added `prefer_passphrase_auth' setting in config file which
1649 can be used to set to prefer passwd auth if both passwd and
1650 public key is set. If not set, public key is preferred.
1651 This has effect only when being initiator (responder will try
1654 Added support for authentication with passphrase and public key
1655 at the same time. The passphrase is tried first always since
1656 it is faster to check.
1658 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1660 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1662 * Merged the new SILC Config library, with the server parsing

1706 * Fixed the file transfer's key agreement payload to include
1707 zero port also if the hostname is NULL because it could not
1710 Call file transfer monitor callback now also if error occurs
1711 during key agreement protocol.
1713 Changed the silc_client_file_send interface to return the
1714 SilcClientFileError instead of session id. The session ID
1715 is returned into pointer provided as argument.
1717 Check that the file exists locally before sending the
1718 file transfer request at all.
1720 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1722 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1732 file lib/silcutil/silclog.c.
1734 * Fixed the channel message payload decryption in the function
1735 silc_channel_message_payload_decrypt to not modify the original
1736 buffer before it is verified that the message decrypted
1737 correctly. Otherwise, next time it is called with correct
1738 channel key it won't encrypt since the payload is corrupted.
1739 Affected file lib/silccore/silcchannel.c.
1741 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1753 * Fixed a bug in hash table internal routine for traversing
1754 the table with foreach callback. The current entry may
1755 become invalid in the callback but it was referenced after
1756 the callback returned.
1758 Do not allow auto rehashing of hash table during the
1759 silc_hash_table_foreach operation, for same reasons as it is
1760 not allowed for SilcHashTableList. Affected files are
1761 lib/silcutil/silchashtable.[ch].
1763 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Defined DLLAPI into silcincludes.h and silcwin32.h for

1769 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed private message handling. It used some old code that
1772 caused the client to crash. Affecte file is
1773 lib/silcclient/client_prvmsg.c.
1775 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1777 * Added function silc_client_add_channel,
1778 silc_client_replace_channel_id, and removed functions
1779 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1780 from client library.
1782 * Added cross reference of the joined channels to the
1783 SilcClientEntry, and changed the SilcChannelEntry's
1784 users list to SilcHashTable. The affected files are
1785 lib/silcclient/idlist.[ch].
1787 * Fixed a bug in hash table tarversing. While the hash table
1788 is traversed with SilcHashTableList the table must not be
1789 rehashed. It is now guaranteed that auto rehashable tables
1790 are not rehashed while tarversing the list. Also defined that
1791 silc_hash_table_rehash must not be called while tarversing
1792 the table. Added function silc_hash_table_list_reset that must
1793 be called after the tarversing is over. The affected files are
1794 lib/silcutil/silchashtable.[ch].
1796 * Changed all hash table traversing to call the new
1797 silc_hash_table_list_reset in server and in client library.
1799 * Added function silc_client_on_channel to return the
1800 SilcChannelUser entry if the specified client entry is joined
1801 on the specified channel. This is exported to application as
1802 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1804 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1806 * Fixed founder regaining problem with JOIN command on normal
1807 server. The notify for mode change must be sent always and
1808 not only if !cmd->pending. Affected file silcd/command.c.
1810 * Fixed the WHOWAS command's reply sending to support the
1811 lists correctly. Affected file silcd/command.c.
1813 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * When sending JOIN command to router for processing the
1816 sender's old command identifier was not saved back to the
1817 sender's command context, fixed now. The affected file is
1820 * Create the key in JOIN command of the router did not return
1821 the channel key, added check for this. Affected file is
1824 * Fixed a channel ID update bug in JOIN command reply. Do
1825 not directly upgrade the ID but call the function
1826 silc_idlist_replace_channel_id if the ID was changed.
1827 Affected file silcd/command_reply.c.
1829 * Fixed memory leaks from command calling if it would fail.
1830 Affected file silcd/command.c.

1842 * Removed TRQ from lib/trq, not needed anymore.
1844 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1845 with server connections. Later this will be configurable
1846 in config file after new config file is done. Affected file
1849 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1851 * Fixed a crash in server related to channel announcements.
1852 Affected file silcd/server.c.
1854 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed memory leaks in silc_server_create_new_channel*
1857 functions. Affected file silcd/server.c.
1859 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1860 which ID was changed. This way the router will send the
1861 user list for the channel again, and server won't be in
1862 desync in some rare circumstances. Affected file is
1863 silcd/packet_receive.c.
1865 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1867 * Check for NULL socket pointer in the function

1877 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1879 * Added lib/silcclient/client_ops_example.h as an template
1880 file for application programmers to quickly start using
1881 the SilcClientOperation functions in their application.
1882 Updated the lib/silcclient/README as well to tell about this
1883 nice file made available.
1885 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1887 * Call silc_server_remove_from_channels when removing client
1888 entry when NO_SUCH_CLIENT_ID was received. Affected file
1889 is silcd/command_reply.c.
1891 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1893 * Added server & router operator statistics updating. Affected
1894 file silcd/packet_receive.c and silcd/command.c.
1896 * Fixed the SERVER_SIGNOFF notify handling on normal server
1897 not to save the history information for clients. Same was
1898 fixed earlier in remove_clients_by_server function, but not
1899 here. Affected file silcd/packet_receive.c.
1901 * Raised the default connection-retry count from 4 to 7 in
1902 server. Affected file silcd/server.h.
1904 * Cancel any possible reconnect timeouts when we start the
1905 key exchange. Affected file silcd/server.c.

1912 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1914 * Fixed the NICK command to always give the unformatted
1915 nickname to the one giving the NICK command. If unformatted
1916 nickname is cached already it will be formatted and the
1917 local entry will always get the unformatted nickname.
1918 Affected file lib/silcclient/idlist.c.
1920 * Fixed some double frees from client library commands.
1921 Affected file is lib/silcclient/command.c.
1923 * Fixed CUMODE command in server to assure that no one can
1924 change founder's mode than the founder itself, there was a
1925 little bug. Affected file silcd/command.c.
1927 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1929 * Removed the SilcClientCommandDestructor from the client
1930 libary, it is not needed anymore. Affected files are
1931 lib/silcclient/silcapi.h, command[_reply].[ch],
1932 client_notify, idlist.c.
1934 * Fixed GETKEY command to first resolve client, and then
1935 resolve the server only if the client was not found, instead
1936 of resolving both at the same time. Affected file is
1937 lib/silcclient/command.c.
1939 * Added silc_client_start_key_exchange_cb and lookup the
1940 remote hostname and IP address before starting the key
1941 exchange with server. The affected file is
1942 lib/silcclient/client.c.
1944 * The server's public key is now saved using the IP address
1945 of the server and not the servername for the filename.
1946 The hostname public key filename is checked as an fall back
1947 method if the IP address based filename is not found.
1949 Fixed the GETKEY command to save the fetched server key
1950 in correct filename.
1952 Print the remote server's hostname now when new key is
1953 received during connection process. Affected file is
1954 irssi/src/silc/core/client_ops.c.
1956 * Return always our own public key to the client if it asks
1957 for it with GETKEY command. Affected file silcd/command.c.
1959 * Removed the use_auto_addr variable from default config
1960 file since it was in wrong section. Affected file is
1963 * Fixed TOPIC_CHANGE notification to not route it when it
1964 was sent using silc_server_send_notify_to_channel function.
1965 Affected file silcd/command.c.
1967 * Fixed silc_server_send_notify_kicked to send the kicker's
1968 Client ID also, it was missing. Affected files are
1969 silcd/command.c, silcd/packet_send.[ch].
1971 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1973 * Do not save client history information in SERVER_SIGNOFF.
1974 Fixes the bug in normal server that it does not detect
1975 the client becoming valid after the server becomes back
1976 online. Affected file silcd/server_util.c.
1978 * Added `sock_error' field into the SilcSocketConnection
1979 context. When error occurs during socket operation (read
1980 or write) the error is saved. Added also new function
1981 silc_socket_get_error to return human readable socket error
1982 message. Affected files are lib/silcutil/silcsockconn.[ch],
1983 lib/silcutil/unix/silcunixsockconn.c, and
1984 lib/silcutil/win32/silcwin32sockconn.c.
1986 * The server now prints the socket error message in the
1987 signoff for client. Affected file silcd/server.c.
1989 * Fixed the `created' channel information sending from router
1990 to server in JOIN command. Checks now whether the channel
1991 really was created or not and set it according that.
1993 Fixed the JOIN command to use the client entry's current
1994 ID during the joining procedure instead of the one it sent
1995 in the command (it is checked though), since it can change
1996 between the packet processing and command processing, and
1997 would just case unnecessary pain in the client end. Affected
1998 file silcd/command.c.
2000 * Fixed a channel key payload sending to use correct channel
2001 ID when the server was forced to change the channel's ID by
2002 router. Router sent the key payload with the old Channel ID.
2003 Affected file silcd/packet_receive.c.
2005 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2007 * Call silc_server_save_channel_key only if the key payload
2008 was provided in the JOIN command's command reply. Affected
2009 file silcd/command_reply.c.
2011 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2013 * Fixed silc_mp_sizeinbase to return the value correctly with
2014 MPI. Affected file lib/silcmath/mp_mpi.c.
2016 * Fixed the stop_server signal to correctly stop the scheduler
2017 and gracefully stop the server when SIGTERM or SIGINT signals
2018 are received. Affected file silcd/silcd.c.
2020 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2022 * Simple handling of TERM and HUP signals. Also added some log
2023 flushing call around. Affected file is
2026 * Fixed small bugs in silclog.c. Now buffering output will take
2027 effect after 10 seconds since startup: This will ensure that
2028 no important startup messages are lost. Also output redirection
2029 will preserve original format ([Date] [Type] message).
2030 Affected file is lib/silcutil/silclog.c.
2032 * Added two options to the config file, in the logging section:
2033 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2034 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2036 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2038 * Do not print the warning about log files not being initialized
2039 more than once to avoid excess logging. Affected file is
2040 lib/silcutil/silclog.c.
2042 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2043 the SIM copying in make install in Makefile.am.pre.
2045 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2047 * Rewritten silclog APIs. Globally interesting changes follows:
2048 silc_log_set_files() changed to silc_log_set_file().
2049 silc_log_set_callbacks() changed to silc_log_set_callback().
2050 ROBOdoc documented silclog header file.
2051 SilcLogCb now returns bool to wether inihibit the default
2052 handler or not (to keep the old behaviour return always TRUE).
2053 The new APIs should also fix the problem of the
2054 silcd_error.log file that was written in the current directory.
2057 Log files streams will remain opened after silc_log_set_file()
2058 call, means less CPU usage notably on high traffic servers.
2059 File streams are now full buffered, and flushed to the disk
2060 every 5 minutes, lesses HD activity and CPU usage.
2061 Messages can be redirected, allowing admins to configure
2062 one single logfile for all server messages.
2063 the silc_log_quick global variable to activate fast-logging.
2064 Affected files lib/silcutil/silclog.[ch]
2066 * Changed some code to conform new silclog APIs. Affected
2067 files are doc/example_silcd.conf.in, silcd/server.c
2068 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2071 * Fixed a memory leak that could occur in some situations.
2072 Affected file silcd/serverconfig.c.
2074 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2076 * Added the silc_client_del_client to remove the client from
2077 all channels as well. Affected file lib/silcclient/idlist.c.
2079 * Fixed the client library to correctly remove the client
2080 from all channels when the client entry is being destroyed.
2081 Affected file lib/silcclient/client_notify.c, command.c.
2083 * Added auto-nicking support to the client library. If the
2084 applicatio now sets client->nickname it will be sent to the
2085 server after connecting by the library. This way for example
2086 SILCNICK (or IRCNICK) environment variables will have effect
2087 and always change the nickname automatically to whatever
2088 it is wanted. Affected file lib/silcclient/client.[ch].
2090 * Renamed silc_server_command_bad_chars to the
2091 silc_server_name_bad_chars and moved it to the
2092 silcd/server_util.[ch]. Added also new function
2093 silc_server_name_modify_bad to return nickname that
2094 includes bad characters as new nickname without those
2095 bad characters. This check and modify is now used in
2096 silc_server_new_client when the username is initially set
2097 as nickname, so it must be checked to be valid nickname.
2098 Affected file silcd/packet_receive.c.
2100 * The nickname length is now taken from the packet for real
2101 and not trusted to strlen() since it clearly can return
2102 wrong length for nickname including bad characters. This
2103 also applies to channel names. Affected file silcd/command.c.
2105 * Removed the lib/silcsilm/modules directory. Modules are now
2106 compiled into the lib/silcsim. Fixed the copying of the
2107 modules to follow symbolic links in Makefile.am.pre.
2109 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2111 * Fixed silc_string_regexify list creation. Fixes bugs with
2112 BAN and INVITE commands in server. The affected file is
2113 lib/silcutil/unix/silcunixutil.c.
2115 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Removed the command destructor entirely from the server's
2118 command and command reply routines. It is not needed, and
2119 its usage was buggy and caused crashes. Affected files are
2120 silcd/command[_reply].[ch].
2122 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2124 * Cancel protocol and NULL sock->protocol if timeout
2125 occurred during protocol. Affected file silcd/server.c.
2127 * Cancel protocol timeouts always before calling the final
2128 callback, to assure that after final callback is called
2129 no other state will be called for the protocol anymore.
2130 Affected file silcd/protocol.c.
2132 * Print error log if incoming connection configuration could
2133 not be found. Affected file silcd/server.c.
2135 * Fixed JOIN command to correctly save the founder mode
2136 to the client on normal SILC server, when the channel
2137 was created by the router. Affected file silcd/command.c.
2139 * Fixed LIST command (hopefully) to send correct reply
2140 packets. Affected file silcd/command.c.
2142 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * The silc_packet_receive_process now returns FALSE if the
2145 read data was invalid packet, and TRUE if it was ok.
2147 The server now checks that if unauthenticated connection
2148 sends data and its processing fails the server will close
2149 the connection since it could be a malicious flooder.
2151 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2153 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Make sure the warning about error opening a log file is
2156 printed only once and not everytime it fails (produces
2157 too much useless log). Affected file lib/silcutil/silclog.c.
2159 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2161 * Made the silc_server_daemonise() function more readable.
2162 Affected file silcd/server.c.
2164 * Pid file is now optional, the user may comment it out from
2165 the config file. Removed define SILC_SERVER_PID_FILE, we
2166 don't need a default any longer. Affected file
2167 configure.in.pre, lib/Makefile.am.pre.
2169 * Make some use of the pid file. The server now dies at startup
2170 if it detects a valid pid file on his path. The server would
2171 die anyway in this circumstance, because of the bind() failure.
2172 Affected file silcd/silcd.c.
2174 * No longer compiling lib/dotconf.
2176 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Fixed JOIN command parsing not to crash. Affected file
2179 lib/silcclient/command.c.
2181 * Fied the NICK_CHANGE notify to add the new client entry
2182 even it is resolved. This removes an <[unknown]> nick
2183 thingy bug in the client. Affected file is
2184 lib/silcclient/client_notify.c.
2186 * Do not try to allocate 0 bytes (efence does not like it)
2187 in lib/silccore/silccomand.c when encoding payload.
2189 * Do not take IRCNICK as nickname in Irssi SILC client since
2190 it is not possible to set nickname before hand connecting
2191 the server (TODO has an entry about adding auto-nicking
2194 * Changed the silc_server_command_pending to check whether
2195 there already exists an pending entry with the specified
2196 command, command identifier and pending callback. This is
2197 to fix IDENTIFY and WHOIS related crashes that may register
2198 multiple pending commands with same identifier. Affected
2199 file silcd/command.c.
2201 * Fixed the server to reconnect to the router even if it
2202 was already reconnecting and EOF was received. This to
2203 fix a possibility that the server wouldn't ever try to
2204 auto-reconnect to the router. Affected file silcd/server.c.
2206 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Fixed the server's password authentication to use the
2209 length of the locally saved password, and not the one
2210 sent in the packet. Affected file silcd/protocol.c.
2212 * Fixed same password authentication problem in the
2213 Authentication Payload handling routines in
2214 lib/silccore/silcauth.c.
2216 * Yet another password authentication problem fixed with
2217 channel password handling in silcd/command.c.
2219 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * If first character of string in silc_parse_userfqdn is '@'
2222 then do not parse it. Affected file is
2223 lib/silcutil/silcutil.c.
2225 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Fixed minor bug in IDENTIFY command reply sending, which
2228 caused various weird problems during JOIN when it was
2229 resolving names for users. Affected file silcd/command.c.
2231 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Fixed the IDENTIFY command reply sending to chech better valid
2234 clients. It was possible to send incomplete list of replies.
2235 Affected file silcd/command.c.
2237 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Added silc_client_command[s]_[un]register functions now to
2240 dynamically register the commands in client library. Removed
2241 the static table of commands. This allows the client library
2242 to call commands without causing the application to know about
2243 what commands library has called.
2245 Removed the INFO command reply kludge to detect when the command
2246 was called by library. Now library use its own command reply
2247 function for INFO command.
2249 Added function silc_client_command_call to call a command.
2250 Application can use it to call command, not access the structure
2253 Now all commands that are sent by the client library (not
2254 explicitly sent by application) use own command reply functions.
2256 Affected files around lib/silcclient/ and in
2257 irssi/src/silc/core/.
2259 * Fixed the WHOIS command reply sending to chech better valid
2260 clients. It was possible to send incomplete list of replies.
2262 Fixed the WHOIS and IDENTIFY to send the request to router
2263 if normal server did not do it and did not find any results.
2265 Affected file silcd/command.c.
2267 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Moved the internal data from SilcClient context into its
2270 own file, not accesible to application. Affected files
2271 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2272 and other files in client library.
2274 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Added doc/examples installation target in Makefile.am.pre.
2279 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2282 commands the found client entry will be removed from the
2283 cache, after notifying application about the error. Affected
2284 file lib/silcclient/command_reply.c.
2286 * Changed the /MSG to check for exact nickname user gave, and
2287 not let `nick' match `nick@host' if it is only one found. Now,
2288 user must type the exact nickname (like nick@host2) even if
2289 there are no more than one same nicks found. This is to avoid
2290 a possibility of sending nickname to wrong nickname since
2291 `nick' could match `nick@host'. Affected file is
2292 irssi/src/core/silc-servers.c.
2294 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Do not print "you are now server operator" or similar when
2297 giving /away command. Affected files are
2298 irssi/src/silc/core/client_ops.c, silc-servers.h.
2300 * Made the silc_server_command_pending_error_check to send
2301 the same command reply payload it received back to the
2302 original sender of the command. This way all arguments
2303 that was received by the server will be received by the
2304 client too. Affected file silcd/command.c.
2306 * Added the silc_idcache_add to return the created cache entry
2307 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2309 * Add global clients to expire if they are not on any channel.
2310 This is because normal server will never know if they signoff
2311 if they are not on any channel. The cache expiry will take
2312 case of these entries. This is done by normal servers only.
2313 The affected files are silcd/command_reply.c,
2314 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2316 * If server receives invalid ID notification for WHOIS or
2317 IDENTIFY and the ID exists in the lists, it is removed.
2318 Affected file silcd/command_reply.c.
2320 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2321 in client then client entry that it matches is searched and
2322 the nickname is printed on the screen for user. Affected
2323 file irssi/src/silc/core/client_ops.c.
2325 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Use cache entry expire time in the LIST command reply to
2328 purge old entries from the cache after the LIST command
2329 reply has been received. This way we don't have non-existent
2330 entries in the cache for too long. Affected file is
2331 silcd/command_reply.c.
2333 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * If we are normal server, and we've not resolved client info
2336 in WHOIS or IDENTIFY from router, and it is global client,
2337 we'll check whether it is on some channel. If it is not
2338 then we cannot be sure about its validity and will resolve it
2339 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2340 file silcd/command.c.
2342 * Search channel by name (if possible) rather than by ID
2343 in IDENTIFY command's command reply. Affected file is
2344 silcd/command_reply.c.
2346 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2349 Updated specs and implemented it. Affected file silcd/command.c,
2350 silcd/packet_send.c and silcd/packet_receive.c.
2352 * Implemented the <founder auth> payload handling in the JOIN
2353 command. If provided all conditions for channel joining
2354 except requirement to provide correct passphrase can be
2355 overrided by the channel founder. Updated the protocol specs.
2356 Affected file silcd/command.c.
2358 Added support for founder auth in JOIN command in client
2359 library. Fixed the parsing of the JOIN command now to support
2360 all options as they should be. The affected file is
2361 lib/silcclient/command.c.
2363 * Optimized the WHOIS and IDENTIFY commands to send the request
2364 to router only if it includes nicknames or other names. If
2365 they include only IDs then check the local cache first before
2366 routing. Affected file is silcd/command.c.
2368 * Added channels topic announcements. Affected file is
2369 silcd/packet_receive.c and silcd/server.c.
2371 * Fixed the silc_server_send_notify_topic_set to really destine
2372 the packet to channel. Affected file silcd/packet_send.c.
2374 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2375 library. Affected file lib/silcclient/client_notify.c.
2377 * Added UMODE announcements. Affected file silcd/server.c.
2379 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Memory leak fixes in:
2383 lib/silcutil/silcsockconn.c
2384 lib/silcske/silcske.c
2385 lib/silcske/groups.c
2387 lib/silccrypt/silcpkcs.c
2388 lib/silccore/silccommand.c
2389 lib/silccore/silcidcache.c
2394 * ROBOdoc documented the lib/silcske/groups.h file and a
2395 bit changed the interface for better.
2397 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2399 * Update the client entry context in the ID cache after
2400 nick change. Affected file lib/silcclient/command.c.
2401 Fixes the CUMODE command when regaining founder privileges,
2402 and a little WHOIS problem.
2404 * Fixed silc_net_gethostbyname to correctly call the
2405 inet_ntop. Affected file lib/silcutil/silcnet.c.
2407 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2409 * Added IPv6 support checking to the configure.in.pre, added
2410 also --enable-ipv6 option to override the check. Affected
2411 file configure.in.pre.
2413 * The silc_thread_create now calls the start function
2414 directly if threads support is not compiled in. Removes
2415 ugly #ifdef's from generic code. Affected files are
2416 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2418 * Added silc_net_gethostby[name/addr]_async to asynchronously
2419 resolve. Affected files are lib/silcutil/silcnet.[ch].
2421 * Added support for rendering IPv6 based server, client and
2422 channel IDs. Affected file lib/silcutil/silcutil.c.
2424 * Added support for creating IPv6 based server IDs. Affected
2425 file is silcd/serverid.c.
2427 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2429 * Added silc_net_gethostby[addr/name] into the
2430 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2431 routines. Added silc_net_is_ip[4/6]. Affected file is
2432 lib/silcutil/unix/silcunixnet.c. All routines that take
2433 address as argument now supports both IPv4 and IPv6 addresses.
2435 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2437 * Fixed LIST command reply sending in server. Affected file
2440 * Server now sends the kicker's client ID in the KICK notify
2441 to the kicked client. Affected file silcd/command.c.
2443 * The client library now parses the kickers client ID and
2444 UI displays it. Affected files lib/silcclient/client_notify.c
2445 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2447 * Made all payload parsing function prototypes consistent.
2448 They all take now const unsigned char * and uint32 pair as
2449 the payload data instead of SilcBuffer. Changes all around
2450 the source tree. Other unsigned char* -> const unsigned char*
2451 changes around the tree as well.
2453 * Optimized SFTP client and server packet sending not to
2454 allocate new buffer for each packet but to recycle the
2455 first allocated buffer. Affected files are
2456 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2458 * Optimized the SFTP client to use SilcList instead of
2459 SilcDList for requests, because it is faster. Affected file
2460 is lib/silcsftp/sftp_client.c.
2462 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2463 into lib/silccore/silcid.[ch].
2465 Renamed silcpayload.[ch] into silcargument.[ch].
2467 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * If client entry is deleted with active key agreement
2470 session, abort the session.
2472 The silc_client_abort_key_agreement now calls the completion
2473 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2475 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2478 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Don't use __restrict in older GCC's. Affected file is
2481 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2483 * silc_net_localhost now attempts to reverse lookup the
2484 IP/hostname. Affected file lib/silcutil/silcnet.c.
2486 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2487 command. It can be used to gain founder privileges at
2488 the same time when joining the channel.
2490 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2491 kicker's client ID as well. Updated protocol specs.
2493 Defined that the server must send SILC_COMMAND_IDENTIFY
2494 command reply with error status to client who sent
2495 private message with invalid client ID.
2497 Updated the protocol specification.
2499 * Added silc_server_send_command_reply to send any
2500 command reply. Affected file silcd/packet_send.[ch].
2502 * Added silc_id_payload_encode_data to encode ID payload
2503 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2505 * The server now send IDENTIFY command reply with error
2506 status if client ID in private message is invalid. Affected
2507 file silcd/packet_receive.c.
2509 * Save the server key file with server's IP address in
2510 the filename instead of hostname. The affected file is
2511 irssi/src/silc/core/client_ops.c.
2513 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2518 * Added libtool support for compiling shared objects in
2519 lib/silcsim. Affected file configure.in.pre and
2520 lib/silcsim/Makefile.am. Original patch by cras.
2522 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2524 * Pid file configuration, and server's config file fixes
2525 patch by toma. Updated CREDITS file.
2527 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Fixed silc_client_channel_message to not try to decrypt
2530 the message twice if it resolved the destination client
2531 information. This could cause of dropping one channel
2532 message. Affected file lib/silcclient/client_channel.c.
2534 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2537 lib/silcclient/client.c. This function is used when the SILC
2538 Client is run under some other scheduler, or event loop or
2539 main loop. On GUI applications, for example this may be
2540 desired to used to run the client under the GUI application's
2541 main loop. Typically the GUI application would register an
2542 idle task that calls this function multiple times in a second
2543 to quickly process the SILC specific data.
2545 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2547 * Fixed silc_server_drop() for dropping the supplementary
2548 groups as well, this could cause a security hole on some
2551 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2556 * Write PID file after dropping privileges. Added -F option
2557 to run server on foreground. A patch by debolaz.
2558 Affected files silcd/server.c, silcd/silcd.c.
2560 * Fixed MOTD to return the MOTD file server name. Affected
2561 file silcd/command.c.
2563 * Added INFO command reply handling to the Irssi SILC Client.
2564 Affected file irssi/src/silc/core/client_ops.c.
2566 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Fixed the silc_idcache_list_* routines to really support
2569 the dynamic list. Fixes a crash. Affected file is
2570 lib/silccore/silcidcache.c.
2572 * Fixed the LIST command reply to really call LIST command's
2573 pending callbacks. Affected file silcd/command_reply.c.
2575 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Update conn->local_entry->nickname after giving NICK
2578 command. Affected file lib/silcclient/command.c.
2580 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2582 * Added the [pid] option to the silcd configuration file
2584 Affected files: serverconfig.[ch] and silcd.c
2586 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Save fingerprint in WHOIS command reply in server.
2589 Affected file silcd/command_reply.c.
2591 * Fixed NICK commands pending callback registration.
2592 Affected file lib/silcclient/command.c.
2594 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Use ++server->cmd_ident when sending commands in server,
2597 instead of random number. Affected file silcd/command.c.
2599 * Fixed GETKEY command reply to call actually GETKEY pending
2600 command callbacks. Affected file silcd/command_reply.c.
2602 * A bit stricter check for nicknames. Check for same nickname
2603 in NICK command also. Affected file silcd/command.c.
2605 * Do not call INFO command everytime client ID changes, only
2606 during first connecting. Affected file lib/silcclient/client.c.
2608 * Set the new nickname only after successful command reply for
2609 NICK command is returned by server. Affected file
2610 lib/silcclient/command.c.
2612 * Remove nicknames from nicklist during server_signoff notify.
2613 Should fix /NAMES bit more. The affected file is
2614 irssi/src/silc/core/silc-channels.c.
2616 * Added `fingerprint' field to the SilcIDListData in the
2617 silcd/idlist.h to hold the fingerprint of the client's
2620 Send the fingerprint of the client's public key in WHOIS
2623 Affected files silcd/command.c, and silcd/idlist.[ch].
2625 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2626 create fingerprint from given data.
2628 * Show the fingerprint of the client's public key in WHOIS.
2629 Affected files irssi/src/module-formats.[ch] and
2630 irssi/src/silc/core/client_ops.c.
2632 * Format the multiple same nicknames also during JOIN and
2633 NICK_CHANGE notifys. Affected file is
2634 lib/silcclient/client_notify.c.
2636 * Do not print error on screen for invalid private message
2637 payload since it can come if someone is sending private
2638 messages with wrong key. Affected file
2639 lib/silccore/silcprivate.c.
2641 * Fixed multiple concurrent /PING crash. Affected file
2642 lib/silcclient/command.c.
2644 * Changed the wrong ID encoding. All IP addresses must be
2645 in MSB first order in encoded format. They were encoded
2646 wrong and was in LSB format. Affected files are
2647 silcd/serverid.c, lib/silcutil/silcutil.c.
2649 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2651 * Call the `connect' client operation through the scheduler
2652 in case of error. Affected file lib/silcclient/client.c.
2654 * Call the `failure' client operation even if the error
2655 occurred locally during a protocol. Affected file is
2656 lib/silcclient/protocol.c.
2658 * Added support of sending LIST command to router from normal
2659 server. This way normal server can get list of all channels
2660 in the network too. Fixed the channel list sending in the
2661 server too. Affected files are silcd/command.c, and
2662 silcd/command_reply.[ch].
2664 * Added silc_server_update_channels_by_server and
2665 silc_server_remove_channels_by_server. They are used during
2666 disconnection of primary router and in backup router protocol.
2667 Affected file silcd/server_util.[ch], silcd/server.c and
2668 silcd/server_backup.c.
2670 * Fixed channel adding to global list in IDENTIFY command
2671 reply in server. Affected file silcd/command_reply.c.
2673 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * If the incoming packet type is REKEY or REKEY_DONE process
2676 that packet always synchronously. Fixes yet another MAC
2677 failed error on slow (dialup) connections. Affected file
2678 lib/silcclient/client.c and silcd/server.c.
2680 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Call check_version SKE callback for initiator too. Affected
2683 file lib/silcske/silcske.c.
2685 * Implemented fix for security hole found in the SKE that was
2686 fixed in the specification few days back; the initiator's
2687 public key is now added to the HASH value computation.
2688 Added backwards support for the old way of doing it too, for
2689 old clients and old servers. Affected file is
2690 lib/silcske/silcske.c.
2692 * Enabled mutual authentication by default in SKE. If initiator
2693 is not providing mutual authentication the responder will
2694 force it. This will provide the proof of posession of the
2695 private key for responder. The affected files are
2696 lib/silcclient/protocol.c and silcd/protocol.c.
2698 * Do not cache anymore the server's public key during SKE.
2699 We do mutual authentication so the proof of posession of
2700 private key is done, and if the server is authenticated in
2701 conn auth protocol with public key we must have the public
2702 key already. Affected file silcd/protocol.c.
2704 * Added new global debug variable: silc_debug_hexdump. If
2705 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2706 file lib/silcutil/silclog.[ch].
2708 * Fixed compilation warning due to char * -> const char *.
2709 Affected files lib/silcutil/silcnet.h, and
2710 lib/silccore/silcauth.[ch].
2712 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Fixed CMODE command when new channel key was created. If
2715 the creation failed the old key was removed. Next time giving
2716 same command would crash the server since the old key was
2717 freed already. Affected file silcd/command.c.
2719 * Fixed the silc_server_announce_get_channels to not crash
2720 on reconnect. Affected file silcd/server.c.
2722 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Added silc_log_set_debug_string function to set a regex
2725 string to match for debug output. Only the function names,
2726 or filenames matching the given debug string is actually
2727 printed. This way it is possible to filter out those debug
2728 strings that user is not interested in.
2730 Fixed a bug in silc_string_regexify.
2732 Affected files lib/silcutil/silclog.[ch], and
2733 lib/silcutil/unix/silcunixutil.c.
2735 * Changed the -d options in both server and Irssi SILC client
2736 to take the debug string as argument. Affected files
2737 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2739 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Added silc_hash_babbleprint to create a Bubble Babble
2742 Encoded fingerprint. The encoding is developed by Antti
2743 Huima (draft-huima-babble-01.txt), and it creates human
2744 readable strings out of binary data. Affected file
2745 lib/silccrypt/silchash.[ch].
2747 * Print the babble print now in addition of fingerprint as well
2748 in Irssi SILC client. Affected files are
2749 irssi/src/fe-common/silc/module-formats.[ch],
2750 irssi/src/fe-common/silc/core/client_ops.c.
2752 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Fixed a security problem found in SKE. The initiator's
2755 public key too is now added to the HASH hash value creation
2756 which is signed by the responder to create the SIGN value.
2757 This will prevent anyone in the middle to lie to the responder
2758 about the initiator's public key. If this is done now, the
2759 man in the middle will get caught. Updated the protocol
2762 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Better installation directory handling. Configure module
2765 paths and other paths automatically to example_silc* files
2766 in doc/. A patch by toma.
2768 * Fixed compiler warning from MPI library, and from SILC RNG.
2771 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2772 It can be configured with ./configure. A patch by toma.
2774 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2776 * Find correct make to use in prepare-clean. A patch by
2777 toma. Affected file prepare-clean.
2779 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2781 * Added irssi variables use_auto_addr, auto_bind_ip,
2782 auto_bind_port and auto_public_ip.
2784 * Changed the interface for silc_client_send_key_agreement
2785 in lib/silcclient/silcapi.h
2789 irssi/src/silc/core/silc-core.c
2791 lib/silcclient/silcapi.h
2792 irssi/src/silc/core/silc-channels.c
2793 lib/silcclient/client_keyagr.c
2796 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Added silc_pkcs_public_key_compare to compare two
2799 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2801 * Check that the client who set the founder mode on the
2802 channel is the same client that is giving the founder
2803 mode to itself. It is done by comparing the saved public
2804 key (it is saved even in the authentication is passphrase).
2805 Affected file silcd/command.c.
2807 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Do not process packet for disconnected socket connection.
2810 Affected file lib/silccore/silcpacket.c.
2812 * Process the DISCONNECT packet through scheduler in the
2813 client library. Affected file lib/silcclient/client.c.
2815 * Fixed the silc_client_packet_parse to not to increase
2816 the packet sequence number if the conn->sock and the
2817 current socket connection is not same. This can happen
2818 for example during key agreement when the conn includes
2819 multiple socket connections (listeners). Affected file
2820 lib/silcclient/client.c.
2822 * The sender of the file transfer request now provides also
2823 the pointer (listener) for the key exchange protocol. If
2824 the listener cannot be created then it sends empty key
2825 agreement and lets the receiver provide the listener.
2827 Added `local_ip' and `local_port' arguments to the
2828 silc_client_file_send. If they are provided they are used,
2829 if not then it will attempt to find local IP address, if
2830 not found or bind fails then the remote client will provide
2833 Affected files are lib/silcclient/client_ftp.c and
2834 lib/silcclient/silcapi.h.
2836 * Extended the FILE SEND command to support defining the
2837 local IP and port for key exchange listener. They are
2838 optional. Affected file irssi/src/silc/core/silc-servers.c.
2840 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Defined to WHOIS command reply the sending of fingerprint
2843 of the client's public key (if the proof of posession of the
2844 corresponding private key is verified by the server).
2845 Updated to the protocol specification.
2847 * Added support of receiving the client's public key's
2848 fingerprint in command reply in client library. Affected
2849 file is lib/silcclient/command_reply.c, and
2850 lib/silcclient/idlist.[ch].
2852 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Do not send over 128 chars long nickname to the server
2855 in NICK command. Affected file lib/silcclient/command.c.
2857 * Do not send over 256 chars long channel names to the server
2858 in JOIN command. Affected file lib/silcclient/command.c.
2860 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Assure that silc_server_close_connection cannot be called
2863 twice for same socket context. Affected file is
2866 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Send error message to application if opening file for
2869 writing during file transfer fails. Affected file is
2870 lib/silcclient/client_ftp.c.
2872 Remove all file transfer sessions for a client that we're
2873 removing from ID cache.
2875 Affected file is lib/silcclient/client_ftp.c.
2877 * Fixed silc_net_addr2bin to return correct address. Affected
2878 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2880 * Fixed file transfer session removing on signoff notify.
2881 Affected file irssi/src/silc/core/silc-servers.c.
2883 * Added the SilcClientFileError to be returned in the monitor
2884 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2885 Affected file lib/silcclient/silcapi.h.
2887 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Fixed a crash in silc_client_ftp_free_sessions and
2890 silc_client_ftp_session_free_client. Affected file
2891 lib/silcclient/client_ftp.c.
2893 * Added `disabled' field in the SilcChannelEntry in the server
2894 to indicate if the server entry is disabled. Affected file

2904 * Fixed a crash in client resolving in client_prvmsg.c in
2905 client library. Affected file lib/silcclient/client_prvmsg.c.
2907 * Do not actually remove the client directly from ID cache
2908 during SERVER_SIGNOFF, but invalidate it. This way we
2909 preserve the WHOWAS info for the client. Affected file
2910 silcd/server_util.c.
2912 * Fixed SERVER_SIGNOFF notify handling in the server. The
2913 server is now able to process incoming SERVER_SIGNOFF notify
2914 for a server that it doesn't even know about. It will remove
2915 the clients provided in the notify. Affected file
2916 silcd/packet_receive.c.
2918 * Check for partial packet in data queue after every packet that
2919 was found from the queue. Return and wait for more data if
2920 there is partial data in queue. Affected file is
2921 lib/silccore/silcpacket.c.
2923 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Added SilcClietFileError enum to indicate error in
2926 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2927 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2928 Affected files lib/silcclient/silcapi.h and
2929 lib/silcclient/client_ftp.c.
2931 * Check that newsize in silc_buffer_realloc is larger than
2932 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2934 * Added better monitor of file transfers. It now monitors
2935 key agreement protocol during the file transfer too. Added
2936 error reporting too. Affected files
2937 irssi/src/silc/core/silc-servers.c,
2938 irssi/src/fe-common/silc/module-formats.[ch].
2940 * Wrote a help file for FILE command.
2942 * Added silc_rng_global_get_byte_fast to get not-so-secure
2943 random data as fast as possible. Random data is read from
2944 /dev/urandom if available and from the SILC RNG if not
2945 available. It is used in padding generation. Affected file
2946 lib/silccrypt/silcrng.[ch].
2948 * All packets in client library are now processed synchronously.
2949 Optimized packet processing a lot. Affected file
2950 lib/silcclient/client.c.
2952 * All server connection packets are processing synchronously
2953 now in server, to optimize packet processing. Affected file
2956 * Include files are installed now only in Toolkit distribution
2957 if make install is given. Affected files: all Makefile.am's.
2959 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Assure that silc_client_notify_by_server_resolve does not
2962 resolve the client information multiple times. If it cannot
2963 be found by the first it cannot be found at all. Affected
2964 file lib/silcclient/client_notify.c.
2966 * Fixed WHOWAS command reply calling. Affected file
2967 lib/silcclient/command_reply.c.
2969 * Removed all references to silc_idlist_get_client from the
2970 Irssi SILC client since that call is internal call used by
2971 the library. The Irssi SILC client will use now client
2972 retrieval functions found in silcapi.h.
2974 * Fixed a bug in resolving nickname info before sending
2975 private message. It used freed memory. Affected file
2976 irssi/src/silc/core/silc-servers.c.
2978 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Assure my_channels statistics cannot go negative in server.
2981 Affected files silcd/server.c, silcd/server_util.c.
2983 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2997 * Added silc_net_localip to return local host's IP address.
2998 Affected file lib/silcutil/silcnet.[ch].
3000 * If key exchange or rekey protocol is active for a connection
3001 parse all packets syncronously since there might be packets
3002 in packet queue that we are not able to process without first
3003 processing packets before them. Affected file silcd/server,
3004 lib/silcclient/client.c.
3006 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3007 whether library should continue processing the packet.
3008 Affected file lib/silccore/silcpacket.h.
3010 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3038 silc_file_open and silc_file_close. Affected files
3039 lib/silcutil/silcutil.[ch].
3041 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Resolve the client info when received private message or
3044 channel message for a client which nickname we don't know.
3045 Affected files lib/silcclient/client_prvmsg.c and
3046 lib/silcclient/client_channel.c.

3054 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3055 is incomplete and is being resolved, it won't be resolved
3058 Make sure also that USERS command reply does not resolve
3059 twice information. Affected file is
3060 lib/silcclient/command_reply.c.
3062 Make sure that silc_client_get_clients_by_list does not
3063 resolve twice same information.
3065 * Check for valid client->id in the silc_server_free_client_data.
3066 Affected file silcd/server.c.
3068 * Fixed /GETKEY nick@server not to crash if the server entry
3069 is not found. Affected file lib/silcclient/command.c.
3071 * Fixed the silc_server_check_cmode_rights to check the
3072 requested modes correctly. Affected file silcd/command.c.
3074 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Better checks for non-printable chars in nick added.
3077 Affected file silcd/command.c.
3079 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Call the silc_server_udpate_servers_by_server in the
3082 primary router that comes back online in the backup resuming
3083 protocol. Otherwise it routes packets wrong. Affected file
3084 silcd/server_util.[ch], silcd/server_backup.c.
3086 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3089 lib/silcutil/silcbuffmt.[ch].
3091 * Redefined the SILC packet header to include the padding
3092 length. Affected file lib/silccore/silcpacket.[ch].
3094 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3095 length for maximum padding up to 128 bytes). Affected
3096 file lib/silccore/silcpacket.h.
3098 * Removed all backwards support for old 0.5.x MAC thingies.
3099 The SILC packet header change makes it impossible to be
3100 backwards compatible.
3102 * Send the ENDING packet with timeout in the backup resuming
3103 protocol. This is to assure that all routers has connected
3104 to the primary router. Affected file silcd/server_backup.c.
3106 * Changed the RNG to take the first IV from random data. It
3107 used to take it from zero actually. Changed the RNG also
3108 to use /dev/urandom during session. /dev/random is used
3109 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3111 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Changed the SILC packet header to have the first two bytes
3114 (the packet length) encrypted. Affected files aroung the
3115 code tree, lib/silccore/silcpacket.[ch]. Removed the
3116 SilcPacketCheckDecrypt callback. It is not needed anymore
3117 since the silc_packet_receive_process will determine now
3118 whether the packet is normal or special.
3120 * Implemented the unidirectional MAC keys. Affected files
3121 lib/silcske/silcske.c, silcd/protocol.c and
3122 lib/silcclient/protocol.c.
3124 * Implemented the packet sequence number to the MAC computation.
3125 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,

3131 * Allow backup router to announce servers. All servers
3132 announced by backup router are added to the global list
3133 automatically. Update hte server's socket to our primary
3134 router also when backup router announces a server.
3135 Affected file silcd/packet_receive.c.
3137 * Do not update the client->router in the function
3138 silc_server_udpate_clients_by_server if the client is on
3139 global list. We might fail to find any specific server
3140 for locally connected clients and local cell clients. They
3141 should still use the `from' and not `to' as client->router.
3142 This fixes backup router resuming protocol. Affected file
3143 silcd/server_util.c.
3145 * Decrease channel statistics count only if the channel
3146 deletion worked. Affected files are silcd/server.c and
3147 silcd/server_util.c.
3149 * Added silc_server_update_servers_by_server to update origin
3150 of all server entries. Used during backup router protocol.
3151 Affected files silcd/server_util.[ch], silcd/server.c. and
3152 silcd/backup_router.c.
3154 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3155 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3156 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3157 lib/silccrypt/silchmac.c.
3159 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Assure that router cannot reroute the same channel message
3162 to the sender. Affected file silcd/packet_receive.c.
3164 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Made better checks that the channel message is not sent
3167 to the router it came from. Affected file is
3168 silcd/packet_send.c. Fixed memory leak too.
3170 * Announce informations for incoming router connection, but
3171 only after checking if it is replaced by backup router.
3172 Affected file silcd/packet_receive.c.
3174 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Fixed the backup resuming protocol to work in multiple
3177 router environment. Affected file silcd/server_backup.c.
3179 * Route packet only to one router in the function
3180 silc_server_packet_send_to_channel. Affected file is
3181 silcd/packet_send.c.
3183 * Fixed silc_server_send_notify_dest to set the broadcast
3184 flag. Fixed the silc_server_send_notify_topic to actually
3185 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3186 Affected file silcd/packet_send.c.
3188 * Changed the SFTP Filesystem interface. Changed the
3189 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3190 the filesystem operation function. The SilcSFTPFilesystem
3191 is now a context that is allocated by all filesystem allocation
3192 functions and it already includes the operations structure
3193 and filesystem specific context. It is given as argument
3194 now to the silc_sftp_server_start. This made the interface
3195 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3196 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3198 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Changed the backup router adding and getting interfaces
3201 in the server. The router that will be replaced by the
3202 specified backup router is now sent as argument. Affected
3203 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3206 * Added silc_net_addr2bin_ne to return the binary form of
3207 the IP address in network byte order. Affected files
3208 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3210 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Check for existing server ID in silc_server_new_server
3213 and in silc_server_connect_to_router_final and remove the
3214 old entry if it exists. Affected file silcd/packet_receive.c,
3217 * Send the channel message always to only one router, either
3218 in upstream or downstream. Affected file is
3219 silcd/packet_send.c.
3221 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Wrote the definition of the backup resuming protocol to the
3224 protocol specification.
3226 * Removed one redundant channel key generation from normal
3227 server during joining procedure. Removed one redundant
3228 channel key sending from server to router during joining
3229 procedure. Affected file silcd/command.c.
3231 * Made minor bugfixes to the backup router resuming protocol.
3232 Affected file silcd/server_backup.c, server.c.
3234 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Added --disable-asm configuration option. Affected files
3237 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3240 * Implemented the backup resuming protocol that is used to
3241 resume the primary router position in the cell after the
3242 primary router comes back online. Affected files
3243 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3244 and silcd/server_util.[ch].
3246 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Sleep two (2) seconds after sending QUIT command to server.
3249 Affected file lib/silcclient/command.c.
3251 * Assure that if outgoing data buffer is pending do not force
3252 send any data. Affected file silcd/packet_send.c.
3254 * Assure that if outgoing data buffer is pending do not force
3255 send any data. Affected file lib/silcclient/client.c.
3257 * Implemented the backup router support when the primary router
3258 goes down. The servers and routers can now use the backup
3259 router as new primary router without loosing connectivity.
3261 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3264 in the server to indicate disabled entry. All data read
3265 from the connection will be ignored and no data is sent
3266 for entry that is disabled. Affected files are
3267 silcd/idlist.h, silcd/server.c.
3269 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Created SFTP client and server test programs in the
3272 lib/silcsftp/tests directory.
3274 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Implemented memory filesystem (virtual filesystem) for
3277 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3280 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Implemented the SFTP (SSH File Transfer Protocol) to the
3283 lib/silcsftp. It includes SFTP client and SFTP server
3286 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Moved lib/silccore/silcprotocol.[ch] to the
3289 lib/silcutil library.
3291 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3292 take variable argument list pointer as argument. Affected
3293 file lib/silcutil/silcbuffmt.[ch].
3295 * Added silc_buffer_set function that is used to set data
3296 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3297 Affected file lib/silcutil/silcbuffer.h.
3299 * Changed various routines in the core library to use the new
3300 silc_buffer_set instead of allocating new buffer only for
3303 * Added 64-bit value formatting and unformatting support to the
3304 silc_buffer_[un]format routines. Affected file is
3305 lib/silcutil/silcbuffmt.[ch].
3307 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3308 to includes/bitmove.h.
3310 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Fixed channel user mode saving in client library. Affected
3313 file lib/silcclient/command[_reply].c.
3315 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Defined the file transfer to the SILC Protocol. Added
3318 new packet type SILC_PACKET_FTP and defined File Transfer
3319 Payload. The mandatory file transfer protocol is SFTP
3320 (SSH File Transfer Protocol). Affected file in addition
3321 of the internet draft is lib/silccore/silcpacket.h.
3323 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3324 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3325 is used as part of backup router protocol when the primary
3326 router of the cell is back online and wishes to resume
3327 the position as primary router.
3329 * Redefined the MAC generation keys in the protocol. The
3330 same key is not used anymore in both direction. Both
3331 direction will now use different keys for sending and
3332 receiving. This fixes a potential security flaw. This
3333 change causes incompatibilities in the protocol.
3335 * Redefined also the MAC computation from the packet.
3336 An packet sequence number is now added to the MAC
3337 computation. This prevents possible replay attacks against
3338 the protocol. This change too causes incompatibilities
3341 Added `sequence' field to the SilcPacketContext to hold
3342 the current sequence number for the packet.
3344 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Added `created' field to the SilcIDListData in the file
3347 silcd/idlist.h to indicate the time when the entry was
3350 * Added `created' field to the SilcChannelEntry too. Affected
3351 file silcd/idlist.h.
3353 * Added `creation_time' aguments to all the announcement functions
3354 in the server. If it is provided then only the entries that
3355 was created after the provided time frame are actually
3356 announced. Affected file silcd/server.[ch].
3358 * The protocol says that the Channel ID's IP address must be
3359 based on the router's IP address. Added check for this in
3360 the silc_server_new_channel when processing incoming New Channel
3361 Payload. Affected file silcd/packet_receive.c.
3363 * Print out the correct version with --version in SILC client.
3364 Affected file irssi/src/silc/core/silc-core.c.
3366 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Fixed WHOWAS command to check for completnes of the client
3369 entry always, not just when the command is coming from client.
3370 Affected file silcd/command.c.
3372 * Added new function silc_server_packet_queue_purge to purge the
3373 outgoing data queue to the network. After the function returns
3374 it is guaranteed that the outgoing packet queue is empty.
3375 Affected file silcd/packet_send.[ch].
3377 * Purge the outgoing packet queue in the rekey protocol's final
3378 callback to assure that all rekey packets go to the network
3379 before quitting the protocol. Affected file silcd/server.c.
3381 * Added silc_client_packet_queue_parse as similar function as
3382 in server to the client library. The affected file is
3383 lib/silcclient/client.c.
3385 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Splitted silcd/server.c and created silcd/server_util.[ch]
3388 for utility functions.
3390 * Added new socket flag SILC_SF_DISABLED to indicate that the
3391 connection is open but nothing can be sent to or received from
3392 the connection. Affected file lib/silcutil/silsockconn.[ch].
3393 The checking for disabled socket is checked in the low level
3394 silc_socket_write and silc_socket_read functions.
3396 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3398 * Allow only nicknames and channel names that fits into the
3399 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3401 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3403 * When processing JOIN command reply in server check that if
3404 the channel exists in our global list we'll move it the local
3405 list. Affected file silcd/command_reply.c.
3407 * Fixed the check whether client is joined on the channel already
3408 in JOIN command. Affected file lib/silcclient/command.c.
3410 * Fixed the JOIN command reply to check whether the channel
3411 already exists. Affected file lib/silcclient/command_reply.c.
3413 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * Added silc_ske_status_string to map the SKE error numbers
3416 to readable strings. The affected files are
3417 lib/silcske/silcske[_status].[ch].
3419 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Do not show the private channels on the WHOIS channel list
3422 as it is not allowed by the protocol. The affected file is
3425 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Assure that the packet length digged from the actual packet
3428 is something sensible in the silc_packet_decrypt_rest_special
3429 in lib/silccrypt/silcpacket.c.
3431 * Free and NULL the allocated pointer in silc_hmac_alloc if
3432 the HMAC allocation fails. The affected file is
3433 lib/silccrypt/silchmac.c.
3435 * Print the selected security properties to the log files in
3436 the server. Affected file silcd/protocol.c.
3438 * Add SKE's reference counter even if calling the completion
3439 callback manually. Otherwise it goes negative, although it
3440 does not cause any problems. The affected file is
3441 lib/silcske/silcske.c.
3443 * Remove the client entry with short timeout after giving the
3444 KILL command. Affected file lib/silcclient/command.c.
3446 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3447 case all found clients are already disconnected (WHOWAS would
3448 found them) in the server. Affected file silcd/command.c.
3450 * Update the last_receive (time of last data received) to be
3451 updated only when received private or channel message so that
3452 the idle time showed in WHOIS makes more sense.
3454 * Added boolean field `valid' in to the SilcClientEntry in the
3455 client library to indicate whether the entry is valid or not.
3456 This fixes the nickname change bug on channel when changing
3457 the nickname to be same than the old (like nick to Nick) the
3458 nickname formatter doesn't set the new nick anymore to Nick@host.
3459 Affected file lib/silcclient/idlist.[ch].
3461 * Now actually fixed the nickname changing on disconnection.
3462 Added new function silc_change_nick to the Irssi SILC Client.
3463 Affected file irssi/src/silc/core/client_ops.c,
3464 irssi/src/silc/core/silc-nicklist.[ch].
3466 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Check that the public key exists in the GETKEY command before
3469 trying to encode it. Affected file silcd/command.c.
3471 * Print some notifications on received public keys with GETKEY
3472 command in the Irssi SILC Client. Affected files are
3473 irssi/src/fe-common/silc/module-formats.[ch],
3474 irssi/src/silc/core/client_ops.c.
3476 * Use IDENTIFY command to resolve the server information in the
3477 GETKEY command instead of INFO command. Affected file
3478 lib/silcclient/command.c.
3480 * All command reply functions in the client library now calls
3481 the pending command reply callbacks even if an error has
3482 occurred. The server has done this a long time and now it was
3483 time to move the client library to this as well. Now all
3484 errors can be delivered back to the pending command reply
3485 callbacks if necessary. Affected files are
3486 lib/silcclient/command[_reply].[ch].
3488 * Change the nickname on disconnection back to the username
3489 because in reconnect the server will enforce it to it anyway.
3490 Affected file irssi/src/silc/core/silc-servers.c.
3492 * Fixed a config file parsing bug in the Irssi SILC client.
3493 Affected file irssi/src/silc/core/clientconfig.c.
3495 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * When printing the channel mode on JOIN, verify that the
3498 channel key and channel's HMAC are valid. Affected file
3499 irssi/src/silc/core/client_ops.c.
3501 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3504 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3505 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3507 * Removed channel key rekey task deleting from the function
3508 silc_server_save_channel_key. Affected file silcd/server.c.
3509 Added explicit timeout task context instead that is used to
3510 delete the task if we are registering a new task before the
3511 new task has elapsed.
3513 * When channel key rekey occurs the client library now saves
3514 the old channel key for a short period of time (10 seconds) and
3515 is able to use it in case some is still sending channel
3516 messages encrypted with the old key after the rekey. Affected
3517 file lib/silcclient/[idlist.h|client_channel.c].
3519 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3521 * Added check to the silc_server_new_id_real to not accept
3522 new ID if it is the sender's own ID. Affected file is
3523 silcd/packet_receive.c.
3525 * Assure that we do not announce ourself or the one we've
3526 sending our announcements when we're router and are announcing
3527 servers to our primary router. Affected file silcd/server.c.
3529 * Fixed silc_server_command_identify_check_client to assemble
3530 correct WHOIS packet. It send corrupted WHOIS packet and
3531 caused problem with router to router connections. Affected
3532 file silcd/command.c.
3534 Fixed also silc_server_command_whois_check the same way
3535 as for the IDENTIFY command.
3537 * Added new SilcIDListStatus to the server in the SilcIDListData
3538 structure. The status now includes the current status of
3539 the entry (like registered, resolved etc.). Affected file
3540 silcd/idlist.[ch]. Defined a bunch of different status types
3541 as well. This replaced the old boolean registered field as well.
3543 Added resolve_cmd_ident field to the SilcClientEntry structure
3544 too so that if the entry is for example being resolved so
3545 another command may attach to the same pending command reply
3546 without requiring to resolve the same entry again. This concept
3547 should optimize the WHOIS and the IDENTIFY resolving under
3548 heavy load by taking away unnecessary resolving for entries
3549 that are being resolved already.
3551 Added support for adding multiple pending commands for one
3552 command idenfier. Affected file silcd/command[_reply].[ch].
3554 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3555 before deleting the data. Otherwise the hash table will have
3556 freed data in comparison functions. Affected file is
3557 silcd/command_reply.c.
3559 * Fixed silc_idlist_replace_client_id to add the new entry to
3560 the cache with NULL nickname. Otherwise there will be invalid
3561 memory as the nickname after the nickname is freed. Affected
3562 file silcd/packet_receive.c.
3564 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3565 saved into wrong slots because the previous number of entries
3566 was not taken into account. Affected file silcd/idlist.c.
3567 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3569 * If we are router and we receive JOIN notify to a channel that
3570 does not have any users then notified client is marked as the
3571 channel founder, as it is it. The affected file is
3572 silcd/packet_receive.c
3574 * Added to the extended hash table API's table_del_*ext functions
3575 the destructor as argument too, so that the caller can decide
3576 which destructor to use or whether to use destructor at all.
3577 Affected file lib/silcutil/silchashtable.[ch].
3579 * Fixed ID Cache purging. It actually deleted the entries from
3580 the hash table after the data was freed. The hash table ended
3581 up comparing freed memory. The affected file is
3582 lib/silccore/silcidcache.c.
3584 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3586 * Fixed Irssi SILC client's KILL command's HELP syntax.
3588 * The USERS command now resolves the detailed user information
3589 if the userinfo field is missing. Affected file is
3590 lib/silcclient/command_reply.c.
3592 * Do not print error in silc_file_read if the read file does
3593 not exist. Just silently return NULL. Affected file is
3594 lib/silcutil/silcutil.c.
3596 * Fixed the silc_log_output to not wine about NULL filename
3597 and to not create some bogus " " filename. Affected file is
3598 lib/silcutil/silclog.c.
3600 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Fixed various printing bugs on the user interface in the
3603 Irssi SILC Client. Minor changes that were forgotten from
3606 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Fixed the configure.in.pre and the compilation and distribution
3609 environment to support the new autoconf 2.52. That version is
3610 now required to compile the CVS trunk.
3612 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3614 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3615 to generally parse user@fqdn format strings. Affected file
3616 lib/silcutil/silcutil.c.
3618 * Added nickname_format and nickname_force_format fields to the
3619 SilcClientParams structure. The first one defines the format
3620 for the nicknames that the library will enforce if the receives
3621 multiple same nicknames. The second one is boolean value and
3622 can be used to force the library to always enforce the format
3623 to the nicknames regardles whether there are multiple nicknames
3624 or not. This configurable formatting was employed to flexibly
3625 support accessing multiple nicknames from the user interface.
3626 The userinterface can now set the nicknames to what ever format
3627 they prefer. Affected file lib/silcclient/silcapi.h.
3629 Added function silc_client_nickname_format to the file
3630 lib/silcclient/idlist.c. It performs the nickname formatting.
3632 Added new field `hostname´ to the SilcClientEntry context.
3633 It holds the hostname of the client. Affected file is
3634 lib/silcclient/idlist.h.
3636 * Irssi SILC Client sets the nicknames in nick@hostn format.
3637 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3638 irssi/src/silc/core/silc-core.c.
3640 The WHOIS printing now also shows both the real nickname and
3641 the formatted nickname so that user knows how to access the
3642 user if there are multiple same nicknames cached. Affected
3643 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3644 printing formatting too to take the hostname now as a separate
3645 argument. The Affected file is
3646 irssi/src/fe-common/silc/modules-formats.[ch].
3648 * Changed the silc_client_get_clients_local to accept the formatted
3649 nickname as argument. It accepts the real nickname too but the
3650 formatted nickname can be used to find the true entry from
3651 multiple entries. Affected file lib/silcclient/silcapi.h and
3652 lib/silcclient/idlist.c.
3654 * Added nickname_format_parse field to the SilcClientParams.
3655 It is a callback function provided by the application to parse
3656 the nickname out of the formatted nickname string. The library
3657 calls it to get the nickname from the formatted string. Since
3658 the application generally knows better the format of the nickname
3659 string it parses it instead of the library, even though library
3660 encodes the formatted string. If the callback function is not
3661 provided then the library will use the string as is. The
3662 affected file is lib/silcclient/silcapi.h.
3664 * All the nickname strings passed to the client library in
3665 commands are now expected to be formatted nickname strings.
3666 If the command does not support the formatted nickname string
3667 it will assume that the sent string is the actual nickname.
3668 Affected file lib/silcclient/command.c.
3670 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Added public key authentication support to OPER and SILCOPER
3673 commands in the client library. Affected file is
3674 lib/silcclient/command.c.
3676 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Changed the get_auth_methdod client operation to be asynchronous.
3679 It can be async if the application resolves the authentication
3680 method from the server during the negotiation. Added new
3681 SilcGetAuthMeth completion callback that the application will
3682 call after resolving the authentication method.
3684 Added function silc_client_request_authentication_method that
3685 the application can use to resolve the authentication method
3686 from the server. Added also SilcConnectionAuthRequest callback
3687 that the library will call after the server has replied. The
3688 application can call this function if it does not know the
3689 current authentication method.
3691 Affected files are lib/silcclient/client.c and
3692 lib/silcclient/silcapi.h.
3694 * The Irssi SILC client now automatically resolves the authentication
3695 method incase any configuration information is not present (and
3696 currently there never is). The affected file is
3697 irssi/src/silc/core/client_ops.c.
3699 * Fixed public key authentication from the client library.
3700 Affected file lib/silcclient/protocol.c. Changed also the
3701 protocol specification about the public key authentication in
3702 the connection authentication protocol. The actual data to be
3703 signed is now computed with a hash function before signing.
3705 * Fixed the public key authentication from the server as well.
3706 Affected file silcd/protocol.c.
3708 * Removed the mlock()'s from the memory allocation routines.
3709 Affected file lib/silcutil/silcmemory.c. The ./configure does
3710 not check anymore for the mlock(). Affected file is
3713 * Fixed USERS command in server to allow the execution of the
3714 command for private and secret channels if the client sending
3715 the command is on the channel. Affected file silcd/command.c.
3717 * Fixed silc_client_get_clients_local to return the clients
3718 count correctly. It could return wrong value. Affected file
3719 lib/silcclient/idlist.c.
3721 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3724 types. The assembler optimizations seemed not to like 64-bit
3725 data types. The assmebler optimizations thus are now enabled
3726 also for BSD systems as opposed to only enable them for Linux.
3728 * Do not check for threads at all on BSD systems. Affected
3729 file configure.in.pre.
3731 * Removed -n and -h options from the Irssi SILC Client since
3732 they are not used in silc.
3734 * Fixed the prime generation to assure that the first digit
3735 of the generated random number is not zero since our conversion
3736 routines does not like number strings that starts with zero
3737 digit. If zero digit is seen the random number is regenerated.
3738 This caused some corrupted RSA keys when the zero first digit
3739 was met. Affected file lib/silcmath/silcprimegen.c.
3741 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Fixed WIN32 configuration in the ./configure script.
3744 Fixed to include xti.h on environments that has it.
3745 Patches by Carsten Ilchmann and andrew.
3747 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3749 * Changed the silc_id_create_client_id to be collision
3750 resistant. It is now assured that there cannot be created
3751 two same client ID's. I suspect that some weird bugs in
3752 the server were actually caused by duplicate Client IDs.
3753 Affected file silcd/serverid.[ch]. A router receiving
3754 new ID now also assures and informs the sending server
3755 if the ID caused collision.
3757 * Changed the silc_id_create_channel_id to also assure that
3758 there are no collisions.
3760 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3762 * Statement about ignoring the Mutual Authentication flag when
3763 performing rekey with PFS was a bit misleading. It is ignored
3764 if it was set in the initial negotiation, it cannot be even
3765 set in the rekey. Fixed in the ke-auth draft. Started the
3766 new versions of the protocol drafts in the doc/.
3768 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Fixed a bug in silc_client_command_identify_save when saving
3771 new channel information. The channel name was no duplicated
3772 and caused crash on exit. Affected file is
3773 lib/silcclient/command_reply.c.
3775 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Fixed the getkey command handling in the server. Send just
3778 empty OK reply to the sender if the key could not be fetched
3779 (but everything else was ok, like the key just was not available).
3780 Changed the public key parameter to optional in the protocol
3781 specs so that empty OK reply can be sent. Affected file
3784 Added a message to Irssi SILC client to tell to user if the
3785 server did not return a public key.
3787 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3789 * Fixed a channel key regeneration bug. It registered new
3790 timeout tasks exponentially until all system resources were
3791 used. Affected file silcd/server.c.
3793 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Added the SILC Document generator to the scripts/silcdoc.
3796 It can be used to generate the Toolkit Reference Manual out
3797 of the source tree. Internally it will also use the RoboDoc
3798 generator now imported in util/robodoc.
3800 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3802 * Added couple of return's in rekey protocol if error orccurred
3803 during the protocol. The execution must be terminated.
3804 Affected file silcd/protocol.c. Also, terminate the protocol
3805 always with timeout.
3807 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * The client's Client ID was created initally from the wrong
3810 nickname (it could have been in format nick@host) in the
3811 silc_server_new_client. Affected file silcd/packet_receive.c
3813 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Added some SILC_LOG_ERROR's to various error conditions
3816 if client could not be added to ID cache. Affected files
3817 silcd/packet_receive.c and silcd/server.c.
3819 * When client's sock->user_data is freed, NULL also the
3820 client->router and client->connection pointers. Added check
3821 for these pointers being NULL to various places around the
3822 code. Affected file silcd/server.c.
3824 * Added client->data.registered == TRUE checks to various
3825 places around the code to assure that unregistered client's
3826 are not handled when it is not allowed. Affected file
3829 * Added `bool registered' fields to all
3830 silc_idlist_[server|client]_get_* routines to indicate whether
3831 the fetched client needs to be registered or not. Affected
3832 file silcd/idlist.[ch].
3834 * Add your own entry as registered to the ID cache in the
3835 server. Affected file server.c.
3837 * Fixed a bug in silc_server_new_server. The SilcServer was
3838 set as the new server's context instead of SilcServerEntry.
3839 This naturally caused some weird bugs.
3841 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Do not delete the channel rekey task when adding it
3844 for in silc_server_create_channel_key.
3846 * Changed the silc_server_create_channel_key to return
3847 TRUE or FALSE to indicate the success of the channel key
3850 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Fixed MSVC++ project files and added missing files to
3853 Makefiles under win32/.
3855 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Do not add TCP_NODELAY flag if the operating system
3858 does not have it defined. Affected files are
3859 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3861 * Fixed buffer overflow from Irssi SILC Client. Affected
3862 file irssi/src/fe-common/core/themes.c.
3864 * Fixed double free in client library in the file
3865 lib/silcclient/client.c when disconnecting from server.
3867 * Applied double free patch from cras to Irssi SILC client.
3868 Affected files irssi/src/core/[modules/expandos].c
3870 * Fixed the disconnection handling to Irssi SILC Client.
3871 The application must call silc_client_close_connection
3872 in ops->connect client operation in case of failure of
3873 the connection. Affected file is
3874 irssi/src/silc/core/client_ops.c.
3876 * Do not set sock->protocol to NULL in the function
3877 silc_client_close_connection after executing the protocol's
3878 final callback since the sock might not be valid anymore.
3879 Affected file lib/silcclient/client.c.
3881 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * Do not enable SILC_THREADS if the linking with libpthread
3884 did not happen. Affected file configure.in.pre.
3886 * Added notion to protocol specification that server must
3887 verify the sent authentication payload with CMODE when
3888 setting the channel founder key. Implemented it to the
3889 server. Affected file silcd/command.c.
3891 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3893 * Added _EXTRA_DIST SILC distribution variable to the
3894 distributions file. It is used to conditionally add extra
3895 files or directories to the specific distribution. Affected
3896 files ./prepare, Makefile.am.pre and distributions.
3898 Removed the `_' from the start of the distribution names.
3901 * Added README.WIN32 for instructions to compile the Toolkit
3904 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3906 * Fixed a double free in disconnection in the server. Affected
3907 file is silcd/server.c.
3909 * Fixed the lib/silcske/groups.c to work now also with GMP
3910 MP library. The string conversion did not work when using
3911 specific base and the base is indicated in the string as well.
3913 * Created win32/ directory which now includes MSVC++ specific
3914 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3915 It will appear only in the toolkit distribution
3917 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Changed the key material distribution function in case when
3920 the hash output is too short. The data is now concatenated
3921 a bit differently than it used to. Made the change to the
3922 SKE protocol specification.
3924 * Added better GMP detection to configure.in.pre. A patch
3927 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Fixed a minor bug in SKE that might cause some problem on
3930 some platforms. Affected file lib/silcske/silcske.c.
3932 * Added the cookie checking for initiator in the SKE. It checks
3933 that the responder returns the sent cookie unmodified. The
3934 affected file is lib/silcske/silcske.c. Added new SKE
3935 error type INVALID_COOKIE that can be sent during the
3936 negotiation. Fixed some memory leaks as well.
3938 * Added the "invalid cookie" error message to Irssi SILC client's
3941 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3943 * Added `task_max' field to the SilcClientParams to indicate
3944 the maximum tasks the scheduler can handle. If set to zero,
3945 default values are used. Affected file lib/silcclient/silcapi.h.
3947 * Fixed memory leaks in silc_client_close_connection. Affected
3948 file lib/silcclient/client.c.
3950 * Added silc_client_del_client_entry to client library to free
3951 all memory of given client entry. Affected file is
3952 lib/silcclient/idlist.[ch].
3954 * Added new functions silc_client_del_channel and
3955 silc_client_del_server to delete channel and server entries.
3956 Affected file lib/silcclient/[silcapi.h/idlist.c].
3958 * Removed silc_client_del_client_by_id from silcapi.h.
3960 * Fixed the INFO command to return the server's own info
3961 correctly when querying by Server ID. Affected file is
3964 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Removed the non-blocking settings in WIN32 code in the
3967 silc_sock_[read/write] and added SleepEx instead. Affected
3968 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3969 of input data is now checked with FIONREAD and ioctlsocket.
3971 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Call silc_schedule_task_del_by_context in the
3974 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3975 Affected file lib/silccore/silcprotocol.c.
3977 * Call silc_protocol_cancel for active protocols in the
3978 silc_server_close_connection if the funtion
3979 silc_server_free_sock_user_data has not been called.
3980 Affected file silcd/server.c.
3982 * Generic tasks cannot be deleted using the del_by_fd
3983 task deleting function since generic tasks does not match
3984 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3986 * Added a notion to SILCOPER help file that the SILCOPER works
3987 only on router server, not on normal server.
3989 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Added for WIN32 support for the new scheduler as well.
3992 Affected file lib/silcutil/win32/silcwin32schedule.c.
3994 * Fixed the SHA1 implementation to work on various platforms.
3996 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3999 API. It is part of the scheduler now. Everything else is
4000 as previously but some functions has changed their names.
4001 Checkout the lib/silcutil/silcschedule.h for the interface.
4002 Updated all applications to use the new interface. Affected
4003 files are lib/silcutil/silcschedule.[ch].
4005 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4007 * Found a bug in the SKE implementation. The HASH value,
4008 specified by the protocol, was not computed correctly. The
4009 public key of the responder was not added to the computation
4010 even though it is mandatory. Affected file lib/silcske/silcske.c.
4011 This unfortunately causes incompatibilities with older
4012 clients and servers.
4014 * Added WIN32 specific network init and uninit functions:
4015 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4016 the Winsock2. Affected file lib/silcutil/silcnet.h and
4017 lib/silcutil/win32/silcwin32net.c.
4019 * Set the socket always to nonblocking mode on WIN32 after
4020 reading data or writing data. Affected file is
4021 lib/silcutil/win32/silcwin32sockconn.c.
4023 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4025 * Fixed various compilation problems under WIN32. Affected
4026 files lib/silcutil/win32/silcwin32thread.c and
4027 lib/silcutil/win32/silcwin32schedule.c.
4029 * Removed all _internal.h #includes from public header
4030 files. Internal headers must never be included from
4033 Removed also the lib/silcske/payload_internal.h file.
4035 * All include files that may be needed (public and some others
4036 included by the public headers) by application developers are
4037 now copied to the ./includes directory. It does not copy any
4038 internal headers. Affected file Makefile.defines.pre and all
4039 Makefile.am's under lib/ and subdirs.
4041 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4043 * Do not change the ~/.silc directory's permissions automatically.
4044 Affected file irssi/src/silc/core/clientutil.c.
4046 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4048 * Do not cancel the protocol in silc_server_close_connection
4049 it might cause recursion. Now cancelled in the function
4050 silc_server_free_sock_user_data. Affected file silcd/server.c.
4052 * Fixed the silc_server_remove_clients_by_server to regenerate
4053 the channel keys correctly finally. Added also new function
4054 silc_server_remove_clients_channels to actually do it.
4055 Affected file silcd/server.c.
4057 * Fixed the silc_server_new_channel to not crash by giving
4058 wrong router to the new channel. Affected file is
4059 silcd/packet_receive.c.
4061 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4063 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4064 which is given as argument to the silc_client_alloc now.
4065 It can be used to configure the client and set various parameters
4066 that affect the function of the client.
4068 * The USERS command in server did not check whether the channel
4069 is private or secret. Affected file silcd/command.c.
4071 * Added new argument to the USERS command in protocol specification.
4072 The USERS command now can take the channel name as argument
4073 as well. Added support for this in client and server and
4074 updated the protocol specs.
4076 * Completed the GETKEY command in client. It can be now used
4077 to fetch also servers public key not only some clients.
4078 Affected files lib/silcclient/command[_reply].c.
4080 * Added silc_client_get_server to return server entry by the
4081 server name. Affected files lib/silcclient/silcapi.h and
4084 * Redefined the IDENTIFY command in protocol specification to be
4085 more generic. It now can be used to query information about
4086 any entity in the SILC Network, including clients, servers and
4087 channels. The query may be based either the entity's name
4088 or the ID. Added support for this in both client and server.
4090 Affected files silcd/command.c and lib/silcclient/command.c
4091 and command_reply.c.
4093 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4094 the _from_client and _from_server functions. Affected file
4097 * Added silc_client_get_channel_by_id_resolve to the file
4098 lib/silcclient/silcapi.h to resolve channel information by
4099 its ID. Added also silc_client_get_channel_by_id that
4100 does not resolve it from the server.
4102 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4104 * Added SilcServerEntry context into the client library
4105 to represent one server. The INFO command now allocates
4106 these to save the resolved server info. For now on the
4107 client library will also keep information about servers,
4108 connected and resolved with INFO.
4110 The INFO command now allocates the SilcServerEntry context
4111 and saves the server info there. The COMMAND_REPLY in
4112 the INFO now returns the parameters to application in
4113 same order as defined in the protocol specification.
4115 The entries are cached in the client->server_cache.
4117 * The INFO command is now issued after received the Client ID
4118 from the server. Affected file lib/silcclient/client.c.
4120 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4121 to the application as the mode changer might be server.
4122 It is guaranteed that NULL is not returned anymore to the
4123 application. Affected file lib/silcclient/client_notify.c.
4125 The ID Type is now also passed to the application so that
4126 it can check whether the returned entry is SilcClientEntry
4129 Added new function silc_client_get_server_by_id to return
4130 the server entry by ID. Affected files are the
4131 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4133 * Do not create the channel in the Irssi SILC Client when issuing
4134 the JOIN command but when received the sucessful JOIN command
4135 reply. Otherwise the channel might get created even though we
4136 could not join it. The Affected file is
4137 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4139 * Fixed a channel joining bug in router. The router must also
4140 check the channel modes, invite and ban lists etc. when serving
4141 the JOIN command sent by normal server. Affected file is
4142 silcd/command.c. The router now resolves the client's
4143 information from the server who sent the JOIN command if it
4144 does not know it, and processes the JOIN command only after
4147 * Changed the SilcCommandCb to take new argument; void *context2.
4148 Affected file lib/silccore/silccommand.h
4150 The second argument in the command callbacks in the server now
4151 includes the SilcServerCommandReplyContext if the command was
4152 called as pending command callback from the command reply.
4153 Otherwise it is NULL. When called as pending the status of the
4154 command reply will be checked and if it was erronous the
4155 error will be sent to the original sender of the command.
4156 This way the client always receives the error messages even
4157 though the server was actually the one who received the error
4158 when it resent the command to router, for example. Affected
4159 files silcd/command[_reply].[ch].
4161 * Fixed sending WHOWAS command's error message to client if
4162 the requested client could not be found. It was missing.
4165 * Changed the CMODE and CUMODE commands reply arguments in the
4166 protocol specification. The Channel ID is now sent in both
4167 of the commands to identify the channel. Implemented this
4168 new feature to the client and server. Affected files
4169 lib/silcclient/command_reply.c and silcd/command.c.
4171 * Made better checks for invite and ban lists in the JOIN
4172 command in server. Affected file silcd/command.c.
4174 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * The server now performs the incoming host IP/DNS lookup
4177 using the silc_socket_host_lookup and thus does not block
4178 the server anymore. Affected file silcd/server.c.
4180 * Completed the multi-thread support for SILC Scheduler in
4181 the lib/silcutil/silcschedule.c.
4183 * Fixed the configure.in.pre to detect the pthread correctly
4186 * Fixed a deadlock in silc_task_queue_wakeup in the file
4187 lib/silcutil/silctask.c.
4189 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4191 * Added new function silc_schedule_wakeup that is used in
4192 multi-threaded environment to wakeup the main thread's
4193 schduler. It needs to be used when a thread adds a new task
4194 or removes a task from task queues. After waking up, the
4195 scheduler will detect the task queue changes. If threads
4196 support is not compiled in this function has no effect.
4197 Implemented the wakeup mechanism to both Unix and WIN32
4198 systems. Affected files are lib/silcutil/silcschedule.[ch],
4199 lib/silcutil/unix/silcunixschedule.c and the
4200 lib/silcutil/win32/silcwin32schedule.c.
4202 * Added new function silc_task_queue_wakeup to wakeup the
4203 scheduler by the specified task queue. Affected file
4204 lib/silcutil/silctask.[ch].
4206 * The silc_socket_host_lookup_start now wakes up the scheduler
4207 after adding the timeout task. Affected file is
4208 lib/silcutil/silcsockconn.c.
4210 * The silc_socket_host_lookup is synchronous now if the threads
4211 support is not compiled in. However, the callback is still
4212 called asyncronously through the scheduler, anyway. Affected
4213 file lib/silcutil/silcsockconn.c.
4215 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4217 * Added new function silc_socket_host_lookup to perform
4218 asynchronous IP and FQDN lookups for the socket connection.
4219 Affected files lib/silcutil/silcsockconn.[ch].
4221 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4223 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4224 that may or may not compile the mutex support in.
4226 Changed the silc_mutex_alloc interface. It allocates the
4227 mutex now to the sent pointer and returns TRUE or FALSE.
4229 Affected file lib/silcutil/silcmutex.h.
4231 * Wrote the SILC Task Queue interface to support multi-threads.
4232 Affected file lib/silcutil/silctask.[ch].
4234 * Wrote the SILC Scheduler to support multi-threads. Affected
4235 file lib/silcutil/silcschedule.c.
4237 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4239 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4240 in lib/silcutil/win32/.
4242 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4244 * Defined SILC Mutex API and SILC Thread API and implemented
4245 them for Unix. Affected files are
4246 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4247 lib/silcutil/unix/silcunixmutex.c and
4248 lib/silcutil/unix/silcunixthread.c.
4250 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4252 * Fixed the silc_server_remove_clients_by_server's channel
4253 key re-generation. The hash table handling was incorrect
4254 and would not work with many channels. Affected file is
4257 * Fixed some memory leaks around the server code.
4259 * Rewrote the silc_server_get_users_on_channel to support IPv6
4260 based Client ID's. Affected file silcd/server.c.
4262 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4263 specification. However, a separate document must be written
4264 to define the detailed signing procedure and the payload
4265 associated with the flag. Defined the flag to the
4266 lib/silccore/silcchannel.h as well.
4268 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4270 * Changed the dynamic tables to static size tables in the
4271 lib/silccrypt/silchmac.c.
4273 * Removed GCC dependencies from the code. A patch by cras.
4275 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4277 * Do not show the error "Error receiving packet bla bla"
4278 in server if it really was not an error (-2 means that reading
4279 is pending). Affected file silcd/server.c.
4281 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4283 * Fixed a possible crash in silc_server_remove_clients_by_server
4284 in silcd/server.c. Fixed there also some memory leaks.
4286 * Fixed the silc_idlist_replace_client_id. It could replace
4287 wrong key in the hash table. Affected file silcd/idlist.c.
4289 * Do not check whether there are global users on the channel
4290 if the channel->global_users is FALSE. Affected functions
4291 silc_server_remove_from_one_channel and
4292 silc_server_remove_from_channels in silcd/server.c. Also,
4293 do not check if the removed client is local as we can be
4294 sure that global client was not removed from the channel
4295 and checking for global users is not needed.
4297 * The silc_server_remove_clients_by_server now re-generates
4298 the channel keys correctly for those channels that had
4299 clients removed from them. Affected file silcd/server.c.
4301 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4303 * Found the reason of random crashes in the server. We weren't
4304 ignoring the SIGPIPE signal (which can be sent in write())
4305 and it crashed the server. Affected file silcd/silcd.c.
4307 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * Assure that sock->user_data is not NULL in the function
4310 silc_server_packet_send in silcd/packet_send.c.
4312 * Disconnect the remote connection if it could not be added
4313 to any ID lists in the server. The affected file is
4316 * Check in silc_server_packet_send[_real/dest] that the
4317 socket is not disconnecting and ignore the data if it is.
4318 Affected file silcd/packet_send.c.
4320 * Define inline to __inline on native WIN32 compilation.
4321 Affected file includes/silcwin32.h.
4323 * Added some explicit type casts for inline code since MSVC
4324 require them. Affected files lib/silcutil/silcbuffer.h,
4325 lib/trq/silcdlist.h and lib/trq/silclist.h.
4327 * Print warning in log files from now on if the packet
4328 decryption fails. Affected file silcd/server.c.
4330 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4332 * Changed the `say' client operation's interface to accept
4333 new `type' argument to indicate the type of the message sent
4334 by the library. The application may filter the library's
4335 messages according the type. The affected file is the
4336 lib/silcclient/silcapi.h.
4338 * Added two new functions to lib/silcclient/silcapi.h:
4339 silc_client_del_client and silc_client_del_client_by_id.
4340 Affected file lib/silcclient/idlist.c.
4342 * Moved the clientincludes.h from includes/ to silc/ and
4343 serverincludes.h from includes/ to silcd/.
4345 * The modes for the CMODE and CUMODE are now passed as
4346 uint32 for application with COMMAND_REPLY. The affected
4347 file is lib/silcclient/command_reply.c.
4349 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4351 * /WHOIS without arguments shows client's own information.
4352 Affected file lib/silcclient/command.c.
4354 * Changed PING to not accept any arguments. The specs
4355 says that client can ping only the connected server so
4356 requiring an argument is not needed. Affected file is
4357 lib/silcclient/command.c.
4359 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4361 * Fixed a fatal bug in private message sending and reception
4362 encryption and decryption when using private message keys.
4363 The implementation was incorrect and did not follow the
4364 specification. It causd that some of the message were
4365 lost since it did not use the sending and receiving keys
4366 as the protocol suggests. This has been fixed and will cause
4367 incompatibilities with older clients when sending private
4368 message encrypted with private message keys. Affected files
4369 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4370 and various other in Irssi SILC Client.
4372 Added `responder' boolean argument to the functions
4373 silc_client_add_private_message_key[_ske] to indicate when
4374 the key is added as responder or initiator of the key
4377 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4379 * Removed the silc_ske_check_version function and created
4380 a SilcSKECheckVersion callback. Added also a function
4381 silc_ske_set_callbacks that is now used to set all SKE
4382 callbacks. The callback functions are not given to
4383 the SKE functions anymore, but this function is used to
4386 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4388 * Added `silc_version' argument to the silc_client_alloc
4389 to define the version of the application for the library.
4390 The library will use the version string to compare it
4391 against the remote host's (usually a server) version
4392 string. Affected file lib/silcclient/silcapi.h
4394 * Added the KE protocol context to Key Agreement context
4395 in client library so that we can abort the SKE if it
4396 is in process when we get timeout. Affected file is
4397 lib/silcclient/client_keyagr.c.
4399 * Do not resolve the client ID forever if it returns in the
4400 first time that such client does not exist. This was done
4401 for example with private message. Affected file is
4402 lib/silcclient/client_prvmsg.c.
4404 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4406 * Do not add regex.h for WIN32. The affected file
4407 includes/silcincludes.h.
4409 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4410 not work yet 100%. It generates the DLL's automatically
4411 when compiling with --with-win32 under cygwin.
4413 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4415 * lib/contrib/regex.c is not compiled on WIN32.
4417 * Added silc_net_get_socket_opt function to the
4418 lib/silcutil/silcnet.h.
4420 * Added includes/silcwin32.h for WIN32 specific includes
4423 * Do not use ptime structure or any of the posix process
4424 functions on WIN32 in lib/silccrypt/silrng.c.
4426 * Added silc_gettimeofday to provide generic function
4427 for struct timeval on all platforms. Added the function
4428 to lib/silcutil/silcutil.h.
4430 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4432 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4433 library as they clearly belong there. As a plus side we
4434 can make the actual socket connection routines platform
4437 Added also new generic function silc_socket_read and
4438 silc_socket_write (that used to be silc_packet_[read/write].
4439 The implementation of these are platform specific.
4441 * Added WIN32 specific routines of silc_socket_[read/write]
4442 to lib/silcutil/win32/silcwin32sockconn.c.
4444 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4446 * Added preliminary support for native WIN32 compilation under
4447 cygwin (using the -mno-cygwin option for GCC) to the
4448 ./configure.in.pre. The --with-win32 now prepares the
4449 compilation for native WIN32.
4451 * Rewrote the SILC Scheduler interface in the file
4452 lib/silcutil/silcschedule.h. The scheduler is now context
4453 based and does not have anymore any global static scheduler.
4454 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4455 and created lib/silcutil/win32 directory for WIN32 based
4458 * Added Unix specific network routines to the
4459 lib/silcutil/unix/silcunixnet.c and the old
4460 lib/silcutil/silcnet.c includes now only generic routines.
4462 Added WIN32 specific network routines to the
4463 lib/silcutil/win32/silcwin32net.c.
4465 * Added Unix specific utility functions from the
4466 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4468 * Added WIN32 SILC Scheduler to the file
4469 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4472 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4474 * Do not handle JOIN notify in the server if the target client
4475 is not registered (idata->registered == FALSE). The affected
4476 file is silcd/packet_receive.c.
4478 * Update the nickrec->founder in event_cumode in the Irssi SILC
4479 client. Affected file irssi/src/silc/core/silc-channels.c.
4481 * Fixed the CUMODE_CHANGE notify handling in the server when
4482 server and router are announcing their clients on channels.
4483 Now the mode changes are saved and notified correctly. The
4484 affected file is /silcd/packet_receive.c.
4486 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4487 They really did not replace the cache entry in the ID Cache.
4488 Now they do that. Affected file silcd/idlist.c.
4490 * Fixed the KICK notify handling in the Irssi SILC client to
4491 update the channel records so that the kicked client does not
4492 appear to be on the channel. The affected file is
4493 irssi/src/silc/core/silc-channels.c.
4495 * Always update the conn->current_channel when executing command
4496 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4498 * Fixed the KILL notify handling in Irssi SILC client to remove
4499 the killed client on all channels.
4501 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Fixed the silc_parse_command_line to remove extra spaces
4504 from the start and end of the arguments. Affected file is
4505 lib/silcutil/silcutil.c.
4507 * Cancel and free any active protocol in the function
4508 silc_server_close_connection. Affected file silcd/server.c.
4510 * Cancel and free any active protocol in the function
4511 silc_client_close_connction. Affected file is
4512 lib/silcclient/client.c.
4514 * Do not execute the KILL command for clients that are in
4515 history (ie. they are not in the network). Affected file is
4518 * Fixed KILL notify handling, client does not crash anymore.
4519 Affected file irssi/src/silc/core/silc-channels.c.
4521 * Reduced the default packet buffer size from 2048 to 1024 in
4522 lib/silccore/silcpacket.c.
4524 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4525 counter to the SKE context that is incresed when the SKE library
4526 performs async operation outside the library. If the outside
4527 process frees the SKE context and FREED status will be set
4528 and the library will detect after the sync operation that the
4529 libary is freed. The affected files are
4530 lib/silcske/silcske[_status].[ch].
4532 * Resolve the client entry information in the function
4533 silc_client_channel_message to assure that NULL pointer is not
4534 passed as client entry to the application. */
4536 * Fixed the task timeout calculation to assure that there is
4537 never negative timeouts. The affected file is
4538 lib/silcutil/silcschedule.c.
4540 * Fixed the channel user mode notification sending in server.
4541 It was sent point-to-point to the router (or to server by router)
4542 but it needs to be destined to a channel. The routines now
4543 supports sending the channel user mode notifys to the channels
4544 when announcing clients and channels. Affected files are
4545 silcd/server.c and silcd/packet_receive.c.
4547 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4548 It did not actually replace the old channel entry in the cache.
4549 Affected file lib/silcclient/client_notify.c.
4551 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Fixed a possible crash in silc_packet_send_prepare. It now
4554 assures always that there is enough space in the buffer and
4555 at the tail area of the buffer (for MAC).
4557 Fixed the inbound buffer reallocation in silc_packet_read.
4558 It was old code and did not handle the reallocation correctly.
4561 The affected file is lib/silccore/silcpacket.c.
4563 * Fixed buffer overflow in silc_parse_nickname in the file
4564 lib/silcutil/silcutil.c.
4566 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * make install generates new server keys only if there is not
4571 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4574 Added check that if the NOREPLY is set then we will not send
4575 the away message. This avoids infinite loop of away messages
4576 if both clients are away. The affected file is
4577 lib/silcclient/client_prvmsg.c.
4579 * Fixed client crash if /NICK was given without arguments.
4580 Affected file lib/silcclient/command.c.
4582 * Server does not send the invite list in INVITE command back
4583 to the client if the list was not altered. Added this notion
4584 to the protocol spec as well. Affected file silcd/command.c.
4586 Fixed possible crash in INVITE command by checking the
4587 value of silc_server_get_client_route command.
4589 * Fixed the INVITE notify type handling. The arguments are now
4590 taken in correct order and client does not crash. The affected
4591 file is irssi/src/silc/core/silc-channels.c.
4593 Removed the "Inviting xxx to channel" message from the
4594 client library away and let the application handle it.
4595 Affected file lib/silcclient/command.c. Added that message
4596 to Irssi SILC client's message formats.
4598 * Fixed CMODE command crash in client. It now checks the
4599 amount of arguments correctly and does not crash. The affected
4600 file is lib/silcclient/command.c.
4602 * Do not create new channel automatically in silc_channels_join
4603 but check whether the channel by that name already exists.
4604 Affected file irssi/silc/core/silc-channels.c.
4606 * Do not send the SERVER_SIGNOFF to router if the disconnected
4607 entity was the router. Affected file silcd/server.c.
4609 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4610 SILC client as it was missing from there.
4612 Added the handling of the KICK notify to the Irssi SILC client
4613 as it was missing. Added "you have been kicked" message to
4614 Irssi SILC client's message modules formats.
4616 Added the handing of the KILL notify to the Irssi SILC client
4617 as it was missing. Added the kill message module formats
4620 The affected file is irssi/src/silc/core/silc-channels.c.
4622 * The router did not save the channel mode the server announced.
4623 Affected file silcd/packet_receive.c.
4625 * Fixed a possible crash in INFO command in server. If the
4626 server did not provide the server info it crashed. Affected
4627 file silcd/command.c.
4629 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Fixed the GETKEY command in the server to check also the
4632 global list. Otherwise the GETKEY would not work correctly
4633 in normal SILC server. Affected file silcd/command.c.
4635 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Fixed GETKEY crash, it crashed if the command did not succseed.
4639 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4642 is now real and not just an macro interface to GMP.
4644 Removed the entire GMP from the source tree and imported new
4645 NSS MPI library instead. Reason for removing GMP is that it is
4646 extremely large and compiles extremely slow. The NSS MPI
4647 is only a few files and compiles in less than 10 seconds.
4648 The speed is also about the same as GMP. The MPI is imported
4649 to lib/silcmath/mpi.
4651 If the system has GMP installed we will still use the GMP.
4652 If it is not then the NSS MPI will be compiled.
4654 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Merged a long nickname (127 characters long) crash bugfix from
4657 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4659 * Merged a freed memory reference bugfix from Irssi CVS tree.
4660 Affected file irssi/src/core/commands.c.
4662 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Added the server's public key sving and verification to the
4665 server when performing the SKE. This was missing and the
4666 remote server's (or router's) public key was accepted without
4667 checking whether we have it previously or trust it at all.
4668 Affected file silcd/protocol.c.
4670 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Check in the silc_server_timeout_remote if protocol is active
4673 and make sure that the protocol's final callback is called so
4674 that all memory if freed. Affected file silcd/server.c.
4676 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * silc_server_whois_send_reply crashed the server if the nickname
4679 was 127 characters long. Affected file silcd/command.c.
4681 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added sanity check to the silc_server_new_client. If the hostname
4684 is provided inside username then check that the provided hostname
4685 really is the same as the resolved one. If the hostname was not
4686 resolved then check it from the public key. Affected file is
4687 silcd/packet_receive.c.
4689 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4690 if the server disconnected us and the connection is not valid
4691 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4693 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4694 the library to the lib/silcutil/silcutil.[ch].
4696 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Close log file after open. Affected file
4699 lib/silcutil/silclog.c.
4701 * Check whether sock == NULL in silc_client_send_packet and return
4702 if it is. Affected file lib/silcclient/silcclient.c.
4704 * Check rec->entry == NULL in the Irssi SILC Client before
4705 sending the channel message. Affecte file is
4706 irssi/src/silc/core/silc-servers.c.
4708 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Merged a splitted window bugfix from Irssi CVS tree. The
4711 affected file is irssi/src/fe-text/textbuffer-view.c.
4713 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4714 It did not print nickname.
4716 * Improved the distributions system a bit.
4718 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4720 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4721 irssi/src/fe-text/gui-window.c.
4723 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4724 to in-active server. The affected file is
4725 irssi/src/silc/core/client_ops.c.
4727 * Resolve the client in USERS command reply if the entry does
4728 not have username resolved. The affected file is
4729 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4730 command to WHOIS command to really resolve stuff. The USERS
4731 is not used any more in any critical section so WHOIS can
4732 be used even though it might be slower than IDENTIFY.
4734 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4737 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Changed the protocol API a bit more consistent in the
4740 lib/silccore/silcprotocol.[ch].
4742 * Changed the following headers to ROBODoc format:
4744 lib/silccore/silcpayload.h
4745 lib/silccore/silcprotocol.h
4746 lib/silccore/silcsockconn.h
4748 All core library headers are now formatted.
4750 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed a bug in Irssi SILC client; do not show that you are
4753 server/router operator if you really are not. Affected file is
4754 irssi/src/silc/core/client_ops.c.
4756 * Renamed silc_command_free_payload to silc_command_payload_free.
4757 Affected file lib/silccore/silccommand.h
4759 * Added silcmath.h to include the prototoypes of various routines
4760 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4763 * Changed the following headers to ROBODoc format:
4765 lib/silccore/silcchannel.h
4766 lib/silccore/silccommand.h
4767 lib/silccore/silcid.h
4768 lib/silccore/silcidcache.h
4769 lib/silccore/silcmode.h
4770 lib/silccore/silcnotify.h
4771 lib/silccore/silcpacket.h
4772 lib/silcmath/silcmath.h
4774 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added checking to the server code not to start the server if
4777 ciphers and stuff are not configured properly. Affected files
4778 silcd/serverconfig.[h] and silcd/server.c.
4780 * Changed the layout of the header files of the public interfaces
4781 in the SILC libraries. The new layout supports ROBODoc
4782 documentation tool (and some others) so that it is easy to create
4783 a library reference manual. All the other headers and source
4784 code must still follow the CodingStyle document. Also source
4785 code must not include these ROBODoc stuffs, only the headers.
4786 Furthermore, all public interface headers must now be named
4787 by using `silc' prefix, example: silcapi.h, silccipher.h.
4788 Some files were renamed due to this. All the other headers
4789 must not be used as public interfaces. I will update the
4790 CodingStyle document later. Changed following headers, so far:
4792 lib/silcclient/silcapi.h
4793 lib/silccore/silcauth.h
4794 lib/silccore/silcprivate.h
4795 lib/silccrypt/silcdh.h
4797 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Removed silc_client_packet_send_flush from the client library
4802 as it is not needed. Affected file lib/silcclient/client.[ch].
4804 * Added printing of message of unresolved authentication method
4805 to the Irssi SILC client. Added it to the module formats.
4806 Removed the same message from the client library.
4808 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added new distribution feature, DISTLABEL. Every distribution
4811 can define own preprocessor label that can be used in the
4812 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4813 file distributions, acconfig.h.pre and prepare.
4815 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Added Makefile.defines_int to include the actual definitions
4818 for Makefile.defines.in. Tested the new distribution system,
4819 created distributions and tested installation.
4821 * Added AWAY message printing to the Irssi SILC client. Added
4822 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4824 * Added SCONNECT command to call the SILC's CONNECT command.
4825 Cannot use CONNECT directly since Irssi uses that internally.
4826 Affected file irssi/src/silc/core/silc-servers.c.
4828 Added ACTION local command. It is same as ME command but takes
4829 the channel as mandatory argument.
4831 Rewrote some of the Irssi's help files to suite for SILC
4834 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added Makefile.defines[.in] that should for now on be included
4837 in all Makefile.am file in the source tree. That file includes
4838 all common compilation definitions for SILC source tree.
4840 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Minor changes to the ./prepare script to change the package
4843 name according the distribution name to the configure.in.
4845 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Created new distribution system. Added file `distributions'
4848 that defines all the distributions that can be created out of
4849 the SILC source tree. The ./prepare script now reads that
4850 file to determine how to prepare the distributions. The
4851 first argument to the ./prepare is the name of the distribution
4852 and second is the version of the distribution. If given
4853 without arguments it creates the default (toolkit) distribution
4854 with the default version (defined in ./prepare).
4856 All Makefile.am files that are subject to the distributions
4857 are now named as Makefile.am.pre. These are ./Makefile.am
4858 and lib/Makefile.am. Others may be changed later.
4860 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added invite list, ban list, some key management and connection
4863 error message printing to module formats in the Irssi SILC client.
4865 * Added new silc_client_set_away_message to set the away message
4866 that is back to the person who sent private message. The
4867 affected file lib/silcclient/silcapi.h and the
4868 lib/silcclient/client_prvmsg.c.
4870 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Fixed the private message sending in the Irssi SILC client,
4873 added local command KEY to the Irssi SILC client.
4875 Added key management and key agreement message formats to the
4876 irssi/src/fe-common/silc/module-formats.[ch].
4878 Added USERS (alias WHO) printing, server/router operator
4879 indication and LIST command printing to the module formats.
4881 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Fixed channel joining notify handling, cumode notify handling
4884 from Irssi SILC client.
4886 * Added SILC specific module-formats to the Irssi SILC client so
4887 that SILC specific message hilighting, colors etc is possible.
4888 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4890 Added channel mode, channel user mode, actions, notices,
4891 whois and whowas printing to the the module-formats.c.
4893 * Fixed a bug in channel deletion in the server. The channel
4894 is not left to the cache even if the channel founder auth mode
4895 is set when there are no users anymore on the channel. Affected
4896 file silcd/server.c.
4898 * The silc_net_localhost now resolves the entire hostname including
4899 the domain name. Affected file lib/silcutil/silcnet.c.
4901 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Changed the ask_passphrase client operation to be ascynchronous.
4904 It has now a completion callback and a context that the
4905 application must call after it has got the passphrase from
4906 the user. Affected files lib/silcclient/silcapi.h,
4907 lib/silcclient/protocol.c, lib/silcclient/command.c and
4910 Added SilcAskPassphrase callback that the application calls
4911 to deliver the passphrase to the library.
4913 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4914 The public key verification and especially a certificate
4915 verification is asynchronous procedure.
4917 Added new SILC_SKE_STATUS_PENDING status to indicate the
4918 request is pending and a callback will be called to finalize
4921 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4922 indicate that remote end did not send its public key (or
4923 certificate), even though we require it. Added check for this
4924 condition in the SKE. This was a security bug, now fixed.
4926 Defined new SilcSKEVerifyCbCompletion callback that is called
4927 when the verification process is completed.
4929 The affected files lib/silcske/silcske_status.h and
4930 lib/silcske/silcske.[ch].
4932 * Changed the verify_public_key client operation to be async
4933 as well. Defined SilcVerifyPublicKey callback that is used to
4934 indicate the success of the public key verification process.
4936 Changed the server and client to use the new async client
4939 * Changed the Irssi SILC client's internal scheduler to be called
4940 twice as many times as it used to be. As a result the client
4941 should be a bit faster now. Affected file is
4942 irssi/src/silc/core/silc-core.c.
4944 * Added support to Irssi SILC client of asynchronous public key
4945 verification and passphrase inquiry. Affected file is
4946 irssi/src/silc/core/silc-core.c.
4948 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Do not say "You have left channel %s" in client library.
4951 Moved it to the application. Affected files are
4952 lib/silcclient/command.c and silc/client_ops.c.
4954 * Fixed silc_client_get_clients. Command context was not
4955 duplicated and was freed memory in the callback. Affected
4956 file lib/silcclient/idlist.c.
4958 * Do not say "you are now talking..." on JOIN command in the
4959 client library. The appliation must handle it.
4961 * Do not say ".. changed topic to" in command reply in the
4962 client libary. The application must handle it.
4964 * Fixed TOPIC command sending in the client library.
4966 * Fixed a memory leak in silc_client_command_free in the file
4967 lib/silcclient/command.c.
4969 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Imported a modified version of Irssi client to the source tree.
4972 The Irssi will be used to create a new client called
4973 Irssi SILC. Imported to irssi/.
4975 Added silc_core_init_finish function to the Irssi. Affected
4976 file irssi/configure.in.
4978 A lot changes in the Makefile.ams around the irssi tree.
4980 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Do not rehash if the new size is same as the old size of the
4983 hash table, in the silc_hash_table_rehash*. The affected file
4984 lib/silcutil/silchashtable.c.
4986 * Replaced hash_table_del_by_context calls from the server
4987 (when channel->user_list and client->channels) to the
4988 hash_table_del as it is sufficient and faster.
4990 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added silc_hash_table_list, silc_hash_table_get and the
4993 SilcHashTableList structure to provide an alternative way to
4994 traverse the hash table. The affected files are
4995 lib/silcutil/silchashtable.[ch].
4997 * Changed the server's idlist routines to use the hash table
4998 routines to optimize the code.
5000 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5002 * Replaced the client entry's `channel' list and channel entry's
5003 `user_list' list to hash tables for optimized lookup. Changed
5004 the code to use the hash table interface around the code.
5005 Affected file lib/silcd/idlist.[ch].
5007 * Added `auto_rehash' boolean argument to the function
5008 silc_hash_table_alloc to indicate whether the hash table should
5009 auto-rehash when it thinks is appropriate time. It will
5010 increase the hash table size if the there is twice as much
5011 entries in the table than the size of the table, and will
5012 decrease the size if there are twice as less entries than
5013 the size of the table.
5015 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5019 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * silc_idcache_purge_by_context deletes the entry now by context
5022 as it is supposed to do. Affected file lib/silccore/idcache.c.
5024 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5025 client is not anymore valid (WHOWAS givens the info) and not
5026 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5028 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Removed the `data' and `data_len' arguments from the ID Cache
5031 interfaces and added `name' argument. ID Cache does not handle
5032 anymore the binary data only a names associated with given ID.
5034 * When hashing a Client ID with silc_hash_id the entire ID is
5035 not hashed anymore, instead only the hash of the Client ID is
5036 hashed. This way we can access the Client ID from the cache
5037 with Client ID but with the hash of the ID (which is a hash of
5038 the nickname) as well without any difference in performance.
5040 Added also silc_idcache_find_by_id_one_ext to do one on one
5041 searching when we have the actual ID. Added also function
5042 silc_hash_client_id_compare. The affected files are
5043 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5045 * When hashing the name associated with a ID it is always done
5046 in lowercase. This way we can access the cache without worrying
5047 about case-sensitivity, even though, for example nicknames are
5050 * Fixed a bug in server with channel message sending. It put
5051 wrong ID type as destination ID. The affected file
5052 silcd/packet_send.c.
5054 * silc_idcache_del_by_context now deletes from all hash tables
5055 by context. Affected file lib/silccore/idcache.c.
5057 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Changed the client library to use the new ID Cache interface.
5060 Changes around the source tree.
5062 * Added silc_hash_table_rehash_ext to rehash with specific
5063 hash function. Affected file lib/silcutil/silchashtable.[ch].
5065 * Added silc_hash_string_compare to compare two strings in the
5066 hash table. Affected file lib/silcutil/silcutil.[ch].
5068 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Added new function silc_idcache_del_by_context into the
5071 lib/silccore/idcache.[ch].
5073 * Changed the server's ID list routines to use the new ID Cache
5074 interface. Changes around the source tree.
5076 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Added silc_hash_table_del[_by_context]_ext functions in to the
5079 lib/silcutil/silchashtable.[ch].
5081 Removed silc_hash_table_find_all* routines and added new
5082 silc_hash_table_find_foreach to replace them.
5084 Added silc_hash_table_replace_ext function as extended
5085 replacing function. Separated the simple hash table interface
5086 from the extended hash table interface in the file
5087 lib/silcutil/silchashtable.h.
5089 * Fixed minor bugs and changed it to use some of the new
5090 hash table functions in lib/silccore/idcache.c
5092 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Added new function silc_hash_table_find_all to return all keys
5095 in the hash table by the specified key. As the hash table is
5096 collision resistant it also makes it possible to have several
5097 duplicate keys in the hash table. This function may be used to
5098 find all of the keys from the hash.
5100 Added user_context arguments to the SilcHashFunction,
5101 SilcHashCompare and SilcHashDestructor to deliver user specified
5104 Added new fuctions silc_hash_table_find[_all]_ext to do
5105 extended lookup with specified hash and compare functions and
5106 specified user contexts.
5108 Added new function silc_hash_table_add_ext to add the key
5109 with specified hash function and user context.
5111 Added new function silc_hash_table_foreach to traverse all
5112 entrys in the hash table. Added SilcHashForeach callback
5115 Added new function silc_hash_table_del_by_context to delete
5116 the entry only if the context associated with the key matches.
5118 Affected files are lib/silcutil/silchashtable.[ch].
5120 * Removed silc_hash_[server/client/channel]_id and added just
5121 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5122 silc_hash_id_compare to compare two ID's using as the hash table
5123 comparison function. Added also silc_hash_data to hash
5124 binary data and silc_hash_data_compare to compare it.
5126 * Removed silc_idlist_find_client_by_hash as it is not needed
5127 anymore. Affected file silcd/idlist.[ch].
5129 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5130 to use internally the SilcHashTable. The new ID Cache is a lot
5131 faster than the old one. Some of the ID Cache interface was also
5132 rewritten and obsolete and stupid functions were removed.
5134 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Added entry_count field to the SilcHashTable to keep the number
5137 of the entries in the table. Implemented the function
5138 silc_hash_table_rehash. Added new function
5139 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5141 Fixed a minor bug in silc_hash_table_free.
5143 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5144 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5145 into the lib/silcutil/silcutil.[ch].
5147 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Implemented a collision resistant hash table into the
5150 lib/silcutil/silchashtable[ch]. See the header and the source
5151 for the SilcHashTable API.
5153 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Merged dotconf version 1.0.2 into lib/dotconf.
5157 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Do not compile anything in lib/silcsim/* if the SIM support
5160 is not enabled. The tree should now compile without problems
5163 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Compiled the SILC under cygwin. Compiled and tested briefly
5166 without problems. More tests needed. The SIMs didn't compile
5169 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5171 * Fixed possible crash in silc_get_username in the
5172 lib/silcutil/silcutil.c.
5174 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Fixed a va_arg in silc/client_ops.c.
5178 * Oops, RC5 routines were named AES and caused some problems
5179 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5181 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Added new SilcIDIP structure into the lib/silccore/id.h and
5184 replaced the old `ip' fields from all SILC ID's to that type.
5185 This is a step towards IPv6 support.
5187 The silc_id_get_len takes now the ID as an extra argument.
5188 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5189 both IPv4 and IPv6 based ID's.
5191 The affected files are lib/silccore/id.[ch] and other files
5192 around the tree using these routines.
5194 * Removed the ID length arguments in server from various
5195 silc_server_send_notify_* routines -> they are not needed
5198 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Fixed memory leak in silc_encode_pem_file in the file
5201 lib/silcutil/silcutil.c.
5203 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Check minor version as well in the SKE. Affected files are
5206 silcd/protocol.c and lib/silcclient/protocol.c.
5208 * Added --identifier option to the server so that an identifier
5209 can be when creating the public key for the server. Affected
5210 file is silcd/silcd.c.
5212 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5213 lib/silccrypt/silcpkcs.c.
5215 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Register default ciphers and stuff when using -C option with
5218 the server. Affected file sildc/silcd.c.
5220 * Put back the servers public key filename format, it is better
5221 than the new one. For now, the client keys are saved with the
5222 new filename format. The affected file silc/client_ops.c.
5224 * Implemented the Cipher API for the rest of the ciphers that
5225 did not implement it or implemented it the wrong way.
5227 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Register default ciphers and stuff when using the -S option
5230 in the client. Affected file silc/silc.c. Same also when
5231 creating new key pair with -C option.
5233 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Fixed the silc_verify_public_key client operation function to
5236 save the public keys differently. The fingerprint is now
5237 used as filename and not the hostname. This way also the
5238 client keys are saved uniquely and not with hostnames. The
5239 affected file is silc/client_ops.c.
5241 * Trimmed the silc_hash_fingerprint function to remove extra
5242 whitespaces from the end of the fingerprint. The affected
5243 file is lib/silccrypt/silchash.c.
5247 * Added silc_cipher_register_default function to register all
5248 default ciphers. It can be used when configuration files
5249 does not exist and the application does not want any specific
5250 ciphers in any specific order.
5252 The SilcDList is now used as silc_cipher_list dynamically
5253 allocated cipher list. Removed the static list all together
5254 and now all ciphers must be allocated to the dynamic list.
5255 The silc_cipher_alloc routine was changed to check only the
5258 All silc_cipher_* routines that used to return int returns
5261 The affected files lib/silccrypt/silccrypt.[ch].
5263 * The same thing was done to silc_hash_* as for silc_cipher_*
5264 routines. Affected files lib/silccrypt/silchash.[ch].
5266 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5267 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5268 Added also silc_pkcs_[un]register[_default] functions.
5269 Removed the data_context from the PKCS API.
5271 * Added silc_hmac_register_default function to register default
5272 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5273 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5274 to unregister all hmacs at once.
5276 * Register the default ciphers, hash functions, PKCSs and HMACs
5277 if client's configuration file does not exist. The affected
5280 * The client did not load the hash functions from the SIM
5281 modules at all. Added support for this. Affected file is
5282 silc/clientconfig.c.
5284 * When decoding public key with silc_pkcs_public_key_decode, check
5285 the supported algorithm only if PKCS are registered. Affected
5286 file lib/silccrypt/silcpkcs.c. The same was done with the
5287 silc_pkcs_private_key_decode.
5289 * Fixed the SILC List routines to keep the list always in order.
5290 It used to change the list's order when traversing the list but
5291 not it preserves the order. Affected file lib/trq/silclist.h.
5293 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added the client library to use the SilcSocketConnection's
5296 reference counter (by silc_socket_dup) to prevent the bug that
5297 the socket object may be freed underneath async operation.
5299 * The name resolv library checking fixes in the configure.in.pre.
5302 * Created new version of the protocol drafts for future
5303 development. The -03 drafts are the ones that will be changed
5304 in the trunk now and the -02 will remain as they are.
5306 * Send list of CUMODE notifys to the router when announcing
5307 the channel users to the router. Affected file silcd/server.c.
5308 If the router receiving channel founder CUMODE for a channel
5309 that already has channel founder it will send CUMODE notify
5310 to the sender to remove the channel founder rights from the
5311 announced client. Affected file silcd/packet_receive.c.
5313 * The CUMODE notify may now use Server ID as well as the entity
5314 who changes the mode. Updated protocool specs.
5316 * Updated INSTALL and README files.
5318 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * New web pages in the http://silc.pspt.fi. The pages was
5325 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Implemented the [DenyConnectin] config section in the server.
5328 Added silc_server_config_denied_conn to check whether incoming
5329 connection is denied. Affected file silcd/serverconfig.[ch].
5331 * Do not check the ports when checking the incoming configuration
5332 data if the port is 0, meaning any. Affected file is
5333 silcd/serverconfig.c.
5335 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Fixed buffer overflow in silc_string_compare in the file
5338 lib/silcutil/silcutil.c.
5340 * Fixed double free in silc_server_command_leave in the file
5343 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Fixed the version checking in the server. Affected file is
5348 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Fixed the configuration data fetching when accepting new
5351 connections in the server. Affected file silcd/server.c.
5353 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Added `sender_entry' argument to the function
5356 silc_server_packet_relay_to_channel so that we can check
5357 whether some destination actually belongs to the same route
5358 the sender belongs (ie, we must not resend the packet to the
5359 sender). Affected file silcd/packet_send.[ch].
5361 * Added `servername' field to the SilcClientEntry in the server
5362 to hold the name of the server where client is from. Affected
5363 file is silcd/idlist.h.
5365 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Moved the channel message encrypting in the router betwen
5368 router connections from silc_server_channel_message to the
5369 silc_server_packet_relay_to_channel since we want to check
5370 whether we have anybody channel before encrypting anything.
5371 Affected files silcd/packet_[receive/send].c.
5373 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Fixed the [AdminConnection] server config section to support
5376 multiple entries. Affected file silcd/serverconfig.c.
5378 * Added support into the server to check the validity of the
5379 incoming connection before executing any KE or authentication
5382 * The connection configuration is now saved to the KE and
5383 connection auth protocol contexts and not fetched anymore in
5384 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5386 * The local hosts listenning address and port is also resolved
5387 now when starting the server. We want to have the socket object
5388 to include the real address and port for the listener. Added
5389 new function silc_net_check_local_by_sock into the files
5390 lib/silcutil/silcnet.[ch].
5392 * Fixed a broadcast bug in server -> do not broadcast if we
5395 * Fixed a routing bug. Do not route broadcast packets ever.
5396 Broadcast packets must be processed always and not routed since
5397 they may be destined to some other host than yourself and thus
5398 would get routed without no good reason. Affected file is
5401 * Added function silc_server_config_is_primary_route to check
5402 whether primary router connection has been configured (a router
5403 configuration that we are initiating). If there is not, we
5404 will assume that there is only two routers in the SILC network
5405 and we will use the incoming router connection as our primary
5406 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5408 * Changed the order of the broadcasting. Broadcast _after_ the
5409 packet has been processed not before. Affected file is
5412 * Fixed a [ClientConnection] parsing bug. The port was never
5413 parsed correctly thus resulting to port 0. Affected file
5414 silcd/serverconfig.c.
5416 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5417 argument and did not set the broadcast packet flag. Affected
5418 file silcd/packet_send.c. Fixed same bug in the function
5419 silc_server_send_notify as well.
5421 * If we receive NEW_ID packet for our own ID in the server, ignore
5424 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Removed the nickname from the Private Message Payload.
5429 Updated the code and the protocol specs.
5431 * Updated protocol specs for submitting to the IETF.
5433 * Tweaked the Random Number Generator a bit. Affected file
5434 lib/silccrypt/silcrng.c. Exported a new function
5435 silc_rng_[global]_add_noise which can be used to add more
5438 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Do not parse packets with different timeout when protocol
5441 is active -> may cause problem with rekey. Affected file
5444 * When server receives signoff notify it must not create
5445 new channel key if the client is on any channels since the
5446 sender of the signoff notify will create it.
5448 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Added printing of error messages during SKE protocol from the
5451 failure packet sent by server during SKE. Affected file
5454 * Removed the client's failure_callback handling with timeout
5455 and handle it immediately when received.
5457 * The SKE library returned wrong type in SUCCESS and FAILURE
5458 packets. They must be 32 bit MSB not 16 bit MSB.
5460 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Ok, rewrote the logic of the re-key and now it seems to work.
5463 I tested it on high traffic with frequent re-keys without
5464 problems. Added hmac_receive (and renamed hmac to hmac_send)
5465 in SilcClientConnection in lib/silcclient/client.h and
5466 in SilcIDListData in silcd/idlist.h. Also, removed the
5467 SilcPacketParserContext's cipher and hmac fields as they are
5468 not needed anymore and actually caused some problems when
5469 the ciphers and hmac's changed underneath the packet parser.
5471 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * If re-key protocol is active then process the incoming packets
5474 synchronously since we must assure that icoming packets encrypted
5475 with the old key is processed before the new keys is set to
5476 use. This is true other packets than for REKEY packets.
5477 Affected file silcd/server.c. The same was done to client library
5478 as well, affected file lib/silcclient/client.c.
5480 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Fixed bug in client and server to accept the force send if
5483 the packet is send from silc_[server/client]_packet_process
5484 function. Otherwise the packets are never delivered, oops.
5486 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Disable force sending of packets when REKEY protocol is active.
5489 We must assure that no packet is sent directly when rekey is
5490 performed. All packets must be sent through packet queue.
5491 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5492 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5493 function is silc_[server/client]_packet_send_real to check
5496 * Replaced the SIM paths from example config files to
5497 /usr/local/modules. Also, make install creates now
5498 /usr/local/silc/logs directory to hold all the SILC server
5501 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Made the configure.in.pre work on Solaris. Patch by salo.
5505 * Made all ciphers compatible with non-x86 machines. Defined
5506 CBC mode macros into lib/silccrypt/ciphers_def.h.
5508 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Fixed the make install.
5512 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * When MAC computation fails the silc_packet_decrypt returned 0
5515 even though it was supposed to return -1. Fixed this. The
5516 affected file is lib/silccore/silcpacket.c.
5518 * Do not replace the config files in /etc/silc (in make install)
5519 if they already exist. Affected file ./Makefile.am.
5521 * Do not send re-key packets immediately but through packet queue.
5522 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5524 * Changed silc_net_check_host_by_sock to return FALSE if the
5525 IP/DNS could not be resolved. Though, it returns the IP address
5526 now even if it could not resolve it (but returns also FALSE).
5527 Affected file lib/silcutil/silcnet.[ch].
5529 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added silc_pkcs_decode_identifier to decode the public key's
5532 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5533 Added also silc_pkcs_free_identifier. Added also new context
5534 SilcPublicKeyIdentifier.
5536 * Added -S option to the silc client. It is used to dump the
5537 contents of the specified public key file.
5539 * Changed the PKCS api to return the public key length when
5540 setting the public key.
5542 * Fixed a fatal bug in the public and private key file loading.
5543 Affected file lib/silccrypt/silcpkcs.c.
5545 * Execute the packet parsing for client with zero (0) timeout
5546 if the protocol is active. Affected file silcd/server.c.
5548 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Made the key generation options to the silcd program. Added
5551 -C option, equivalent to client's option.
5553 * Added new [ServerKeys] config section to the server. It
5554 configures the server's public and private key.
5556 * Defined generic Public Key Payload into the protocol
5557 specification to send specific type of public keys and
5560 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5561 public key or certificate.
5563 * Implemented the GETKEY command to the server and to the
5564 client library and on user interface.
5566 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Made preliminary `make install' work.
5570 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Added SilcServerRekey context into silcd/idlist.h.
5574 * Added the PFS support as defined in the specification to the
5575 SKE protocol. Affected files lib/silcske/*.c.
5577 * Added `ske_group' field to the SilcServerRekey context to hold
5578 the number of the SKE group that is used with PFS in re-key.
5579 Affected file silcd/idlist.h.
5581 * Added PFS re-key support to the server. Affected file is
5584 * Added silc_protocol_cancel to cancel execution of the next
5585 state of the protocol. Affected file is
5586 lib/silccore/silcprotocol.[ch].
5588 * Added the re-key support with and without PFS to the client
5589 library. Re-key is performed once in an hour, by default.
5591 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5592 Added silc_client_rekey_callback and silc_client_rekey_final.
5593 Affected files are lib/silcclient/protocol.[ch] and
5594 lib/silcclient/client.[ch].
5596 * Removed the `hmac_key' and `hmac_key_len' fields from the
5597 SilcClientConnection structure; not needed. Affected file is
5598 lib/silcclient/client.h.
5602 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Do not ask whether user wants to use the negotiated private key
5605 for private messages, just use it. Affected file is
5606 silc/local_command.c.
5608 * Added `send_enc_key' and `enc_key_len' fields to the
5609 SilcIDListData structure since they are needed in the re-key
5610 phase. Affected file is silcd/idlist.[ch].
5612 * Implemented the simple re-key protocol into the server.
5613 Affected files silcd/server.c and silcd/protocol.[ch]. The
5614 re-key will be performed once in an hour, by default.
5616 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5617 Added silc_server_rekey, silc_server_rekey_callback and
5618 silc_server_rekey_final.
5620 * Removed Tunneled flag from the protocol. Updated the code
5621 and the specifications.
5623 * Adde `pfs' field to the SilcIDListData to indicate whether
5624 the PFS is to be performed in the re-key. Affected file is
5627 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5630 int64 of at least the xintXX size. If void * is less that 4
5631 bytes uint32 * will be used. Defined bool as boolean.
5633 * Changed _ALL_ unsigned long and unsigned int to uint32,
5634 unsgined short to uint16 in the source tree.
5636 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5637 not handle clients that has entry->data.registered == FALSE.
5638 They are not in the network anymore. Affected file is
5641 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Implemented the sending of the SERVER_SIGNOFF notify in the
5644 server. Affected file is silcd/server.c.
5646 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5647 Added also silc_notify_payload_encode_args into the
5648 lib/silccore/silcnotify.[ch].
5650 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5651 Affected file silcd/packet_receive.c.
5653 * Implemented the SERVER_SIGNOFF notify handling in the client
5654 library. Affected file lib/silcclient/client_notify.c. Also,
5655 implemnted the printing of the SERVER_SIGNOFF info to the
5656 application. Affected file silc/client_ops.c.
5658 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5659 if the deleting was successful. Affected file silcd/idlist.[ch].
5661 * Added support for public key authentication in the connection
5662 authentication protocol in the client library. Affected file
5663 lib/silcclient/protocol.c.
5665 * Changed the server's silc_idlist_get_clients_by_* interface
5666 to support already allocated array so that new entries may be
5667 added to pre-allocated array. Affected file silcd/idlist.[ch].
5668 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5669 and command replies.
5671 * All command reply functions in the server now calls the
5672 pending command callback even if error occured. This way the
5673 error will be delivered to the client as well. Affected files
5674 silcd/command.c and silcd/command_reply.c.
5676 * Fixed INFO command to return local server's info if no server
5677 was provided. Affected file lib/silcclient/command.c.
5679 * Removed RESTART command for good. Updated the code and the
5682 * Rewrote parts of the task system. It is a bit simpler now.
5683 Removed unsued task priorities. The affected files are
5684 lib/silcutil/silctask.[ch].
5686 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Moved the USERS printing from the library to the application.
5689 Affected files lib/silcclient/command.c and silc/client_ops.c.
5691 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added channel key re-key support. The re-key is perfomed
5696 only by the router and is done once in an hour. Added `rekey'
5697 field to the SilcChannelEntry in the server. Affected files
5698 silcd/server.c and silcd/idlist.h.
5700 * Added silc_task_unregister_by_context into the file
5701 lib/silcutil/silctask.[ch].
5703 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added SILC_UMODE_GONE mode to indicate when the client is not
5706 present in the SILC network. Added also support to the local
5707 command AWAY that will set this mode. Added support of showing
5708 "xxx is gone" in WHOIS command. The USERS command shows the
5709 gone status as well.
5711 * Fixed setting server and router operator privileges in the
5712 server's UMODE command. Affected file silcd/command.c.
5714 * Merged the SKE KE1 and KE2 payloads into one payload. The
5715 new KE payload is equivalent to the old KE2 payload.
5717 Cleaned up the SKE Start Payload parsing. It now uses the
5718 simple buffer unformatting to do the parsing. A lot faster
5721 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5722 to the SKE that is used to indicate whether both of the SKE
5723 parties should perform authentication. By default only the
5724 responder performs authentication. By setting this flag also
5725 the initiator must do authentication. By default it is unset
5726 since in normal SKE case, client to server connection, only
5727 the responder should do authentication. When doing SKE between
5728 two clients both should perform authentication. Updated the
5729 code and the protocol specs.
5731 * A little fix to IDENTIFY command in the server. Search the
5732 client first by hash not nickname. Affected file is
5735 * Fixed the silc_client_close_connection to support closing
5736 the client to client connections wihtout deleting too much
5737 data. Affected file lib/silcclient/client.c.
5739 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5740 are received if protocol used to be active but is not anymore
5741 the application would crash due to NULL pointer dereference.
5742 Affected files silcd/server.c and lib/silcclient/client.c.
5744 * Added `hash' field to the SilcClientConnection to include
5745 the hash function negotiated in the SKE protocol.
5747 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5748 to set the channel founder authentication data. A client can
5749 claim the founder rights later by providing the authentication
5750 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5751 This way the channel founder can regain the channel founder
5752 privileges even it is left the channel. This works only on
5753 local server and the client must be connected to the same
5754 server to be able to regain the founder rights. Updated the
5755 protocol specs accordingly.
5757 Added support to the CMODE command in the client to set the
5758 founder auth data. Read the README to see how to set it.
5760 Added support to the CUMODE command to claim the founder
5761 rights. Read the README to see how to do it.
5763 Added support for the founder authentication to the Channel
5764 Entry in the server. Affected file silcd/idlist.h.
5766 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5767 server's CMODE command. Affected file silcd/command.c.
5769 * Added the following new functions into lib/silccore/silcauth.[ch]:
5770 silc_auth_get_method and silc_auth_get_data.
5772 * The server now saves the remote hosts public key to the
5773 SilcIDListData pointer. Affected file silcd/protocol.c.
5775 * The normal server now does not remove the channel entry from
5776 the cache if the founder authentication data is set. It used
5777 to remove it if the founder was the last one on the channel on
5778 the server and left the channel. The auth data is saved and
5779 if the channel is re-joined later the old entry is used with
5780 the old auth data. Affected files silcd/command_reply.c and
5783 * Removed the `pkcs' field from the SilcIDListData structure
5784 in the server; it is not used. Affected file silcd/idlist.h.
5786 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Fixed packet processing on slow links. Partial packets were
5789 never re-processed because the incoming data buffer was cleared
5790 by the application. Application must not directly clear the
5791 sock->inbuf, the packet processing routines handle it. Fixed
5792 this in client library and in server.
5794 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Fixed the WHOIS and IDENTIFY send reply function to really
5797 check whether to send list or just one entry. Affected file
5800 * Cleaned up the LEAVE command's channel key distribution. The
5801 affected file silcd/command.c.
5803 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5804 can enforce the channel mode as well. In that case the ID
5805 includes the ID of the server. The code now enforces the
5806 mode change if the router have different mode than the server.
5808 * The notify client operation with CMODE_CHANGE notify can now
5809 return NULL client_entry pointer if the CMODE was not changed
5810 by client. Application must check for this.
5812 * Added <Server ID> argument to INFO command to support server
5813 info fetching by Server ID.
5815 * Added silc_server_announce_get_channel_users to get assembled
5816 packets of channel users of the specified channel. Affected
5817 file silcd/server.[ch].
5819 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5820 was freed underneath the ID Cache.
5822 * Re-announce clients when the server received CHANNEL_CHANGE
5823 notify from the router. Affected file silcd/packet_send.c.
5825 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5828 crashed since it did not handle the fact that there is no cipher
5829 called "3" and didn't check the error condition. Now fixed.
5831 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5832 flag. It can be used to send message requests.
5834 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Implemented the RESTART command in the client.
5838 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5839 notice type messages. Added notice printing to the user
5842 * The channel keys are not re-generated if the channel's mode
5843 is PRIVKEY, ie private key on the channel exists. Affected
5844 files silcd/server.c and silcd/command.c.
5846 * Fixed a little bug in channel message delivery when channel
5847 private keys are set in the server. Affected file is
5848 silcd/packet_send.c.
5850 * Changed the setting on channel->on_channel = TRUE from the
5851 silc_client_save_channel_key to the JOIN command reply. The
5852 key payload is not received if the private channel key is set.
5853 Affected file lib/silcclient/command_reply.c and the
5854 lib/silcclient/client_channel.c.
5856 * When the CMODE_CHANGE notify is sent and the channel private
5857 key mode is removed the channel key must be re-generated in
5858 other cells as well. Added this support for the router in the
5859 silcd/packet_receive.c.
5861 * Added new local command NOTICE to send notice message on
5862 channel. Affected file silc/local_command.[ch].
5864 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added new local command ME to the client. It is used to send
5867 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5868 some action. Affected file silc/local_command.[ch].
5870 * Changed channel_message and private_message client operations
5871 to deliver the message flags to the application. Added also
5872 the `flags' arguments to the silc_client_send_channel_message
5873 and silc_client_send_private_message functions. Affected file
5876 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Redefined the Private Message Payload to support private message
5879 keys and to support the new private message flags. Updated
5880 the protocol specs. Flags makes it possible to have for example
5881 CTCP style messages.
5883 * Added new type SilcPrivateMessagePayload and defined an API
5884 for it in the lib/silcclient/silcprivate.[ch].
5886 * Tested private message private keys successfully. Tested the
5887 private message key set, unset and list commands with the new
5890 * Redefined the Channel Message Payload to include the channel
5891 message flags (equal with private message flags) to support
5892 for example CTCP style messages.
5894 * Defined some of the message (for channel and private message)
5895 flags. Updated the protocol specs and added the flags to the
5896 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5898 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added SilcKeyAgreementStatus type to the key agreement routines
5901 to indicate the current status and error if one occured.
5902 The status types are defined in the lib/silcclient/silcapi.h.
5904 * Added new local command KEY that is used to set and unset private
5905 keys for channels, set and unset private keys for private messages
5906 with remote clients and to send key agreement requests and
5907 negotiate the key agreement protocol with remote client. The
5908 key agreement is supported only to negotiate private message keys,
5909 it currently cannot be used to negotiate private keys for channels,
5910 as it is not convenient for that purpose.
5912 * Fixed a minor pending callback setting bug in the function
5913 silc_client_get_client_by_id_resolve, now the function works.
5914 Affected file lib/silcclient/idlist.c.
5916 * Added function silc_net_get_local_port to get local bound
5917 port by socket. Added to lib/silcutil/silcnet.[ch].
5919 * Added `sockets' and `sockets_count' fields to the SilcClient
5920 object. They hold the sockets of the listenning sockets in
5921 the client. Listenning sockets may be for example the key
5922 agreement server. Affected file lib/silcclient/client.[ch].
5923 Added functions the silc_client_add_socket and the
5924 silc_client_del_socket. They are exported to the application
5927 * Added ~./silc/clientkeys to support other client's public keys.
5929 * Renamed verify_server_key client operation to verify_public_key
5930 and added one argument to indicate the type of the connection
5931 (server, client etc.).
5933 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added silc_server_connection_auth_request to handle the
5936 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5937 silcd/packet_receive.[ch].
5939 * Added silc_server_send_connection_auth_request into the
5940 silcd/packet_send.c to send the connection auth request packet.
5942 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5945 * Fixed the public key authentication in responder side in the
5946 server. The `auth_data' pointer includes the SilcPublicKey
5947 not the path to the public key. Affected file silcd/protocol.c.
5949 * Implemented the public key authentication in the initiator side
5950 in the server. Affected file silcd/protocol.c.
5952 * Removed the [RedirectClient] config section from the server
5953 configuration. Is not needed and I don't want to implement it.
5955 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Cleaned up the CMODE command in the server. It now works
5958 correctly and supports all the modes defined in the protocol.
5959 Affected file is silcd/command.c.
5961 * Added `hmac_name' field to the SilcChannelEntry in the server
5962 to hold the default HMAC of the channel. It can be set when
5963 creating the channel (with JOIN command). Affected files
5966 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5967 type to indicate the change of the current cipher and hmac
5968 on the channel. Client can safely ignore the <cipher> argument
5969 (if it chooses to do so) since the CHANNEL_KEY packet will
5970 force the channel key change anyway. The <hmac> argument is
5971 important since the client is responsible of setting the new
5972 HMAC and the hmac key into use.
5974 * Fixed the CMODE command in the client library as well.
5976 * Tested CMODE command in router environment successfully.
5978 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Show the version of the remote client (or server) when connecting
5981 to the server. It is logged to the log file. Affected file
5982 is silcd/protocol.c.
5984 * Fixed the KILLED notify handling in the client library. The
5985 client must be removed from all channels when receiving the
5988 Also, do not remove the client entry when giving the KILL
5989 command but when the KILLED notify is received.
5991 * Removed silc_idlist_find_client_by_nickname from the server.
5992 Not needed anymore. Affected files silcd/idlist.[ch].
5994 * Implemented the CHANNEL_CHANGE notify type handling to the
5995 server. Affected file silcd/server.c.
5999 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Added silc_server_send_notify_invite to send the INVITE
6002 notify between routers.
6004 * Implemented the INVITE command correctly to the server.
6006 * Implemented the INVITE notify type handling in the server.
6008 * Implemented the INVITE command to the client library and on the
6011 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Added function silc_server_get_client_resolve to find the
6014 client entry by ID from all ID lists and then resolve it
6015 (using WHOIS) if it cannot be found. Affected file is
6018 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Implemented the BAN command to the client library.
6022 * The JOIN command in the server now checks the invite list
6025 * Changed the silc_command_reply_payload_encode_va and the
6026 silc_command_payload_encode_va to support that if argument is
6027 NULL it ignores and checks the next argument. Affected file
6028 lib/silccore/silccommand.c.
6030 * Added silc_server_send_notify_ban to send the BAN notify
6031 type between routers.
6033 * Chaned the silc_notify_payload_encode to support that if
6034 argument is NULL it ignores and checks the next argument.
6035 Affected file lib/silccore/silcnotify.c.
6037 * Tested ban lists in router environment successfully.
6039 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Implemented BAN command to the server, in silcd/command.[ch].
6043 * Removed the BAN and INVITE_LIST modes from the CMODE command
6046 * Added function silc_string_match to regex match two strings.
6047 Affected files lib/silcutil/silcutil.[ch].
6049 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Redefined parts of the SilcChannelEntry in the server to support
6052 the new ban and invite lists.
6054 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Redefined the INVITE command. The same command can be used to
6057 invite individuals to the channel but also to manage the invite
6058 list of the channel (to add to and remove from the invite list).
6059 Updated the protocol specs.
6061 * Added new command SILC_COMMAND_BAN that can be used to manage
6062 the ban list of the channel. Updated the protocol specs.
6064 * Removed the channel modes: the SILC_CMODE_BAN and the
6065 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6066 in the CMODE command. The equivalent features are now available
6067 using INVITE and BAN commands. Updated the protocol specs.
6069 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6070 in the network about change in the current ban list. The notify
6071 type is not used by the client.
6073 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6074 support the invite lists.
6076 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Added new function silc_string_regexify that converts string
6079 including wildcard characters into regex string that can
6080 be used by the GNU regex library. Added into the file
6081 lib/silcutil/silcutil.[ch].
6083 Added silc_string_regex_combine to combine to regex strings
6084 into one so that they can be used as one regex string by
6085 the GNU regex library. Added into the file
6086 lib/silcutil/silcutil.[ch].
6088 Added silc_string_regex_match to match two strings. It returns
6089 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6091 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Imported GNU regex to the soruce tree into lib/contrib.
6094 Fixed some compiler warning from the regex.c.
6096 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Fixed MOTD command in the server to work in router environment.
6100 * Fixed the MOTD command in the client library to support
6101 the server argument in the command.
6103 * Added `nickname_len' argument to the silc_idlist_add_client
6104 in the server, as the `nickname' argument may be binary data
6107 * Added silc_idlist_get_channels to return all channels from
6110 * Implemented LIST command to the server. Affected file is
6113 * Implemented the LIST command to the client library and on the
6116 * Added [<user count>] argument to the LIST command reply.
6117 With private channels the user count is not shown.
6119 * Updated TODO and README.
6121 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * The client entry's data.registered must be TRUE even with
6124 global client entry on global client list. The data.registered
6125 is used to check whether the client is anymore in the network,
6126 for example with WHOWAS command so it must be valid.
6128 * Fixed the WHOWAS command in the server. It now actually works
6129 in router environment. Added function into silcd/command_reply.c
6130 silc_server_command_reply_whowas_save.
6132 * Added silc_idlist_purge function to the silcd/idlist.c
6133 to periodically purge the ID Cache.
6135 * Fixed INFO command in the server. It works now in router
6136 environment. Added <server name> argument to the INFO command
6137 reply. Updated the protocol specs.
6139 * Fixed minor bug in silc_idcache_purge to not purge if the
6140 expire value is zero.
6142 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6143 they were buggy because of the WHOWAS information.
6145 * Fixed local command MSG to handle the async resolving of
6146 the remote client properly. It used to fail the first MSG.
6147 Affected file silc/local_command.c.
6149 * Added `data_len' field to SilcIDCache context.
6151 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Update TODO. Todo in commands in the server.
6155 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6158 used by routers as broadcast packet to inform other routers
6159 about the changed user mode.
6161 Implemented the notify handling in the server. Affected file is
6162 silcd/packet_receive.c. Added the function
6163 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6165 * Added new generic Channel Payload and deprecated the New Channel
6166 Payload. The New Channel Payload is now the generic Channel
6169 * Added new argument `mode' to the silc_server_send_new_channel
6170 as it is required in the Channel Payload now.
6172 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6173 and created a new and real SilChannelPayload to represent the
6174 new generic Channel Payload. Implemented the encode/decode
6175 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6177 * Added silc_server_get_client_channel_list to return the list
6178 of channels the client has joined for WHOIS command reply.
6179 Affected file silcd/server.[ch].
6181 * Implemented the channel list sending in the WHOIS command reply
6182 in server and in the client.
6184 Implemented the channel list displaying on the user interface
6185 as well. Affected file silc/client_ops.c.
6187 * Added silc_channel_payload_parse_list to parse list of Channel
6188 Payloads. It returns SilcDList list of SilcChannelPayloads.
6189 Client for example can use this function to parse the list of
6190 channels it receives in the WHOIS command reply. The caller
6191 must free the list by calling silc_channel_payload_list_free.
6192 Affected files lib/silccore/silcchannel.[ch].
6194 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added one new argument <user mode> to the WHOIS command reply
6197 to return the mode of the user in SILC. Updated the protocol
6200 Implemented it to the server and client.
6202 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Fixed the mode printing on the user interface on joining.
6205 Affected file silc/client_ops.c.
6207 * Implemented the UMODE command and user modes in general to the
6208 client library and to the user interface.
6210 * Implemented the UMODE command to the server.
6212 * The server now sends UNKNOWN_COMMAND error status if client sends
6213 unknown command. Affected file silcd/command.c.
6215 * All server commands now handle the command identifier the right
6216 way when sending the command reply to the client. The client can
6217 use to identify the command replies with the identifier.
6219 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Added silc_server_get_client_route to resolve the route to
6222 the client indicated by the client ID. Affected file is
6225 * Added silc_server_relay_packet as general function to relay
6226 packet to arbitrary destination. This deprecates functions
6227 like _send_private_message_key, _relay_notify etc. Affected
6228 file is silcd/packet_send.[ch].
6230 Removed silc_server_send_key_agreement,
6231 silc_server_send_private_message_key and
6232 silc_server_packet_relay_notify functions from the file
6233 silcd/packet_send.[ch].
6237 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6238 server. Affected file silcd/packet_receive.[ch].
6240 * Implemented the KILL command to the client. Implemented the
6241 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6242 Affected files lib/silcclient/command[_reply].c and
6243 lib/silcclient/client_notify.c. Implemented the KILL notify
6244 printing in the user inteface.
6246 * Fixed a lot silc_parse_nick memory leaks from the client
6247 library in the file lib/silcclient/command.c.
6249 * Changed the silc_server_send_notify_on_channels's `sender'
6250 argument from SilcSocketConnection to SilcClientEntry to
6251 check the sender as entry and not as connection object and not
6252 to send to the client provided as argument. The affected file
6253 is silcd/packet_send.[ch].
6255 * The notify packets that are destined directly to the client used
6256 to not to be processed by the server. Now changed that and the
6257 server processes all notify packets. After relaying the packet
6258 to the client the notify packet is processed in the server.
6260 * The silc_server_free_client_data now checks whether there is
6261 pending outgoing traffic for the client and purges the data to
6262 the network before removing the client entry.
6264 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6267 an client is killed from the SILC Network. Updated the protocol
6270 Added new function silc_server_send_notify_killed to the
6271 silcd/packet_send.[ch].
6273 * Added function silc_server_packet_relay_notify to relay notify
6274 packets that are destined directly to a client. In this case
6275 the server does not process the notify packets but merely relays
6276 it to the client. Affected file silcd/packet_send.[ch].
6278 Added also silc_server_packet_process_relay_notify to check
6279 whereto relay the notify. Affected file is
6280 silcd/packet_receive.[ch].
6282 * Implemented the KILL command to the server.
6286 * Added the backup schema desgined last fall to the protocol
6287 specs for everyone to see. The specification is in the
6288 *-spec-xx.txt draft and the packet type definitions for the
6289 backup routers is in *-pp-xx.txt draft. Thusly, added also
6290 new packet type SILC_PACKET_CELL_ROUTERS.
6292 * A big security problem in the implementation discovered. The
6293 signoff of an client did not cause new channel key generation
6294 which it of course should've done. The channel keys must be
6295 always re-generated when client leaves (or signoffs) the channel.
6296 The silc_server_remove_from_channels funtion now handles
6297 the channel key re-generation.
6299 * Added `sender' argument to the silc_server_send_notify_on_channels
6300 to not to send the client provided as argument. Affected file
6301 silcd/packet_send.[ch].
6303 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6305 * Implemented OPER and SILCOPER commands into the server and
6308 * Added silc_auth_verify and silc_auth_verify_data to verify
6309 the authentication directly from the authentication payload.
6310 It supports verifying both passphrase and public key based
6311 authentication. Affected file lib/silccore/silcauth.[ch].
6313 * Added `hash' field to the SilcIDListData structure. It is the
6314 hash negotiated in the SKE protocol. Affected file is
6317 * Slight redesigning of the SilcAuthPayload handling routines.
6318 Do not send SilcPKCS but SilcPublicKey as argument.
6320 * Implemented the public key authentication support to the
6321 serverconfig. The public key is loaded from the provided path
6322 and saved as authentication data to void * pointer. Thus,
6323 changed the unsigned char *auth_data to void *auth_data;
6325 * Fixed SHUTDOWN command to send the reply before the server
6326 is shutdown. :) Affected file silcd/command.c.
6328 * Fixed fatal bug in CONNECT command. The hostname was invalid
6329 memory and server crashed. Affected file silcd/command.c.
6331 * Fixed fatal bug in CLOSE command. The server_entry became
6332 invalid but was referenced later in the command. Affected file
6335 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Fixed fatal bug in failure packet handling. Server ignored
6338 the failure and thus crashed when it came.
6342 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6345 that the command may be executed only once in (about) 2 seconds.
6346 The old SILC_CF_LAG flag is same but allows command bursts up
6347 to five before limiting.
6349 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6350 server code. Various commands now includes the CF_LAG_STRICT
6351 flag to disallow any kind of miss-use of the command.
6353 * Fixed the silc_buffer_unformat to not to allocate any data
6354 if the length of the data is zero. It used to allocate the
6355 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6357 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Changed the format of AdminConnection configuration section
6360 in the server. Added username of the admin to the format.
6361 Affected files silcd/serverconfig.[ch].
6363 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6364 to return admin configuration data by host, username and/or
6367 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Implemented WHOWAS command to the server. Added the functions:
6371 silc_server_command_whowas_parse,
6372 silc_server_command_whowas_send_reply,
6373 silc_server_command_whowas_from_client and
6374 silc_server_command_whowas_from_server
6376 * Added <Client ID> argument to the WHOWAS command reply. Updated
6377 the protocol specs accordingly.
6379 * Implemented WHOWAS command and command_reply to the client
6382 Implemented the WHOWAS printing on the user interface.
6384 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Added new argument to the WHOWAS command reply, the real name.
6387 It is an optional argument. Updated the protocol specs.
6389 * Added SilcIDCacheDestructor callback that is registered when
6390 the SilcIDCache is allocated. The callback is called when
6391 an cache entry in the ID Cache expires, or is purged from the
6392 cache. Added into lib/silccore/idcache.[ch].
6394 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6395 to destruct the client entries when the cache entry expires.
6396 Other ID Cache's in server and in the client library ignores
6399 * If the ID Cache entry's `expire' field is zero then the entry
6400 never expires. Added boolean `expire' argument to the
6401 silc_idcache_add function in the lib/silccore/idcache.[ch].
6402 If it is TRUE the default expiry value is used.
6404 * Added silc_server_free_client_data_timeout that is registered
6405 when client disconnects. By default for 5 minutes we preserve
6406 the client entry for history - for WHOWAS command.
6408 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added support to the server to enforce that commands are not
6411 executed more than once in 2 seconds. If server receives
6412 commands from client more frequently, timeout is registered
6413 to process the commands. Affected file silcd/command.c.
6414 Added new function silc_server_command_process_timeout.
6416 * Changed NICK_NOTIFY handling in client library to check that
6417 if the client's nickname was changed, so there is no need to
6418 resolve anything from the server.
6420 * Removed error printing from the WHOIS and IDENTIFY commands.
6421 If error occurs then it is ignored silently in the client library.
6422 The application, however, may map the received error to
6423 human readable error string. The application currently maps
6424 the NO_SUCH_NICKNAME error to string.
6426 * Made the command status message public to the application. Moved
6427 them from lib/silcclient/command_reply.c to
6428 lib/silcclient/command_reply.h. The application can map the
6429 received command status to the string with the
6430 silc_client_command_status_message function.
6432 * Added check to the server to check that client's ID is same
6433 as the Source ID in the packet the client sent. They must
6436 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Added dist-bzip hook to the Makefile.am to make bzip2
6439 compressed distributions.
6441 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Server now enforces the maximum length for the nickname and
6444 the channel as protocol specification dictates. 128 bytes for
6445 nickname and 256 bytes for channel name.
6447 * Moved the WHOIS printing to the application. The client libary
6448 does not print out the WHOIS information anymore, the application
6449 must do it. Renamed silc_client_command_reply_whois_print to
6450 the silc_client_command_reply_whois_save.
6452 The client's idle time is also sent to the application now, and
6453 the idle is shown on screen.
6455 * Added silc_client_command_reply_identify_save to save the
6456 received IDENTIFY entries.
6458 * Do not check for channel private keys in message sending and
6459 reception if the channel does not have the PRIVKEY mode set.
6460 Affected file lib/silclient/client_channel.c.
6462 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6465 just surfaced after chaning the JOIN procedure.
6467 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Added silc_client_get_clients_by_list to get client entries
6470 from Client ID list, that is returned for example by JOIN
6471 and USERS command replies. The application should use this
6472 function for example when JOIN command reply is received to
6473 resolve the clients already on the channel (library does not
6474 do that anymore as USERS command reply is not used in the JOIN
6475 procedure anymore). Affected files lib/silcclient/silcapi.h and
6476 lib/silcclient/idlist.c.
6478 * JOIN command reply and USERS command reply returns now SilcBuffer
6479 pointers instead of unsigned char pointers when returning
6480 the client list and mode list.
6482 * Added <Client ID> argument to the JOIN command reply, mainly
6483 for the server to identify for which client the command was
6484 originally sent. Updated protocol specs accordingly.
6486 * Added SilcDlist private_key pointer to the SilcChannelEntry
6487 in the client to support the channel private keys. Affected
6488 file is lib/silcclient/idlist.h.
6490 * Added SilcChannelPrivateKey argument to the function
6491 silc_client_send_channel_message so that application can choose
6492 to use specific private ke if it wants to. If it is not provided,
6493 the normal channel key is used, unless private keys are set.
6494 In this case the first (key that was added first) is used
6495 as the encryption key.
6497 * Implemented the support for channel private key handling.
6498 Implemented the following functions:
6500 silc_client_add_channel_private_key,
6501 silc_client_del_channel_private_keys,
6502 silc_client_del_channel_private_key,
6503 silc_client_list_channel_private_keys and
6504 silc_client_free_channel_private_keys
6506 Affected file lib/silcclient/client_channel.c.
6508 * Added the support for the private keys in the channel message
6509 sending and encryption and in the message reception and
6510 decryption. Affected funtions are
6511 silc_client_send_channel_message and silc_client_channel_message.
6513 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Added SKE's key verify callback to the client library's
6516 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6518 * Removed the statement that server (or router) must send USERS
6519 command reply when joining to the channel so that the client
6520 knows who are on the channel. Instead, the client list and
6521 client's mode list is now sent in the JOIN command reply to the
6522 client who joined channel. This is better solution.
6524 * Added function silc_server_get_users_on_channel and function
6525 silc_server_save_users_on_channel to the silcd/server.[ch].
6527 * Removed function silc_server_command_send_users from the
6530 * Do not show topic on the client library anymore. The topic is
6531 sent in the command reply notify to the application and the
6532 application must show the topic now.
6534 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added client searching by nickname hash into the IDENTIFY and
6537 WHOIS commands in the server as they were clearly missing from
6538 them. Affected file is silcd/command.c.
6540 * Fixed a bug in private message receiving in the client library.
6541 The remote ID was freed and it wasn't supposed, now it is
6544 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Minor fix to the channel payload; allocate the data area, as it
6547 needs to be of specific length.
6549 * If the key agreement port is zero then the operating
6550 system will define the bound port. Affected files are
6551 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6553 * Added new function silc_channel_payload_decrypt into the file
6554 lib/silccore/silcchannel.[ch].
6556 * Moved the channel message etc, check from silc_packet_decrypt
6557 to applications. The library calls now a generic
6558 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6559 when the packet is either normal or special. This was done to
6560 allow more wide range of checking that was not allowed when
6561 the code was in library. Now applications can do virtually any
6562 checks to the packet and return to the library the decision how
6563 the packet should be processed. Affected files are
6564 lib/silccore/silcpacket.[ch].
6566 Added silc_server_packet_decrypt_check to the server and
6567 silc_client_packet_decrypt_check to the client library.
6569 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6570 to send with specified source and destination information.
6572 * Channel message delivery between routers was broken after the
6573 channel key distribution was fixed earlier. The channel key
6574 was used be to distributed to other routers as well which is not
6575 allowed by the protocol. Now this is fixed and channel keys
6576 really are cell specific and the channel message delivery between
6577 routers comply with the protocol specification.
6579 * Fixed various commands in server to check also the global list
6580 for the channel entry and not just the local list. The affected
6581 file silcd/command.c.
6583 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added assert()s to buffer formatting and unformatting routines
6586 to assert (if --enable-debug) when error occurs. Affected
6587 file: lib/silcutil/silcbuffmt.c.
6589 * Changed to auto-reconnect to check whether the remote host is
6590 router and register the re-connect timeout if it is. It used
6591 to check that whether we are normal server, but router must do
6592 auto-reconnect with another router as well. Affected file
6595 * Removed the [<key len>] option from CMODE command as the cipher
6596 name decides the key length, nowadays. See the defined ciphers
6597 from the protocol specification.
6599 * Added [<hmac>] option to the CMODE command to define the HMAC
6600 for the channel. Added SILC_CMODE_HMAC channel mode.
6602 * Added [<hmac>] option for the JOIN command so that user can
6603 select which HMAC is used to compute the MACs of the channel
6606 * Added Hmac field to the Channel Message Payload. The integrity
6607 of plaintext channel messages are now protected by computing
6608 MAC of the message and attaching the MAC to the payload. The
6609 MAC is encrypted. Now, it is clear that this causes some
6610 overhead to the size of the packet but rationale for this is that
6611 now the receiver can verify whether the channel message decrypted
6612 correctly and also when private keys are set for the channel the
6613 receiver can decrypt the packet with several keys and check from
6614 the MAC which key decrypted the message correctly.
6616 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6617 lib/silccrypt/silccipher.[ch].
6619 * Added silc_hash_len to return the digest length into the
6620 lib/silcrypt/silchash.[ch].
6622 * Rewrote parts of Silc Channel Payload interface in the
6623 lib/silccore/silcchannel.[ch]. The encode function now also
6624 encrypts the packet and parse function decrypts it.
6626 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Fixed a minor formatting bug in the SKE's key material processing.
6629 It actually might have processed the keys wrong way resulting
6632 * Redefined the mandatory HMAC algorithms and added new algorithms.
6633 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6634 and hmac-md5 truncated to 96 bits. The mandatory is now
6635 hmac-sha1-96. Rest are optional (including the one that used
6636 to be mandatory). Rationale for this is that the truncated HMAC
6637 length is sufficient from security point of view and can actually
6638 make the attack against the HMAC harder. Also, the truncated
6639 HMAC causes less overhead to the packets. See the RFC2104 for
6642 * Added new [hmac] configuration section. The SKE used to use
6643 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6644 is of course wrong. The official names that must be proposed in
6645 the SKE are the ones defined in the protocol specification
6646 (hmac-sha1-96 for example). The user can configure any hmac
6647 using any hash function configured in the [hash] section. At
6648 least, the mandatory must be configured.
6650 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6652 * Added HMAC list to the SKE proposal list. It has now both
6653 hash algorithm list and HMAC list. This makes the protocol
6654 incompatible with previous versions. The SKE now seems to work
6655 the way it is supposed to work, for the first time actually.
6657 * Defined plain Hash algorithms to the protocol specification.
6660 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Implemented support for key agreement packets into the server.
6663 Added functions silc_server_key_agreement and
6664 silc_server_send_key_agreement. Other than these functions,
6665 server has nothing to do with this packet.
6667 * Added support for private message key packets into the server.
6668 Added functions silc_server_private_message_key and
6669 silc_server_send_private_message_key.
6673 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6674 called in the protocol's final callback instead in the END
6675 protocol state. This makes a little more sense and in the same
6676 time in client we can use the same protocol routines for normal
6677 key exchange and to key agreement packet handling as well.
6679 * Added to both client's and server's KE protocol context the
6680 SilcSKEKeyMaterial pointer to save the key material. We will
6681 bring the key material to the protocol's final callback by doing
6682 this. The final callback must free the key material.
6684 * Added SKE's packet_send callback into client's KE protocol
6685 context so that the caller can choose what packet sending function
6686 is used. This way we can use different packet sending when
6687 doing normal SKE when doing key agreement packet handling (in
6688 the key agreement packet handling we do not want to encrypt
6691 * Implemented the responder side of the key agreement routines
6692 in the client. The client can now bind to specified port and
6693 accept incoming key negotiation. The key material is passed
6694 to the application after the protocol is over.
6696 * Implemented the processing of incoming Key Agreement packet
6697 in the client. Added function silc_client_key_agreement to
6700 * Implemented the intiator side of the key agreement routines
6701 in the client. The client can now initiate key agreement with
6702 another remote client. The key material is passed to the
6703 application after the protocol is over.
6705 * Created client_keyagr.c to include all the key agreement
6708 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6709 SILC_TASK_CALLBACK except that it is not static.
6711 * Created client_notify.c and moved the Notify packet handling
6712 from the client.[ch] into that file.
6714 * Created client_prvmsg.c and moved all private message and
6715 private message key routines from the client.[ch] into that file.
6717 * Create client_channel.c and moved all channel message and
6718 channel private key routines from the client.[ch] into that file.
6720 * Changed silc_client_get_client_by_id_resolve to resolve with
6721 WHOIS command instead of IDENTIFY command, in the file
6722 lib/silclient/idlist.c.
6724 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Implemented the SKE's responder side to the Client library.
6728 * When FAILURE is received to the protocol do not trust it
6729 blindly. Register a timeout to wait whether the remote closes
6730 the connection as it should do it, only after that process the
6731 actual failure. This was changed to both client and server.
6733 * Added client_internal.h to include some of the structures
6734 there instead of client.h in lib/silcclient/.
6736 * Added function silc_task_unregister_by_callback to unregister
6737 timeouts by the callback function.
6739 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Some "Incomplete WHOIS info" errors has been appearing on the
6742 log files. Took away the entry->userinfo check from WHOIS
6743 reply sending. The entry->userinfo is now " " if client did not
6744 provide one. I thought this was fixed earlier but something
6745 is wrong still. Let's see if the error still appears.
6747 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Fixed a minor bug in the login when the channel key is
6750 re-generated in the server. It used to generate the key in
6751 wrong order and thus caused problems in the channel traffic.
6753 * Fixed a minor bug in channel key distsribution after
6754 KICK command. The key was not sent to the router even though
6757 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Added silc_ske_process_key_material_data as generic routine
6760 to process any key material as the SILC protocol dictates. The
6761 function is used by the actual SKE library but can be used by
6762 applications as well. This relates to the private message keys
6763 and the channel private keys since they must be processed the
6764 same way the normal SILC session keys. The protocol dictates
6765 this. Affected files: lib/silcske/silcske.[ch].
6767 Added also silc_ske_free_key_material to free the
6768 SilcSKEKeyMaterial structure.
6770 * Defined silc_cipher_set_key function to set the key for
6771 cipher without using the object's method function. The affected
6772 files: lib/silccrypt/silccipher.[ch].
6774 * Implemented silc silc_client_add_private_message_key,
6775 silc_client_add_private_message_key_ske,
6776 silc_client_del_private_message_key,
6777 silc_client_list_private_message_keys and
6778 silc_client_free_private_message_keys functions in the
6781 Added functions silc_client_send_private_message_key to send
6782 the Private Message Key payload and silc_client_private_message_key
6783 to handle incoming Private Message Key payload.
6785 * Added Cipher field to the Private Message Key payload to set
6786 the cipher to be used. If ignored, the default cipher defined
6787 in the SILC protocol (aes-256-cbc) is used.
6789 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Removed lib/silcclient/ops.h file.
6793 Redefined parts of the SILC Client Library API. Created new
6794 file silcapi.h that deprecates the ops.h file and defines the
6795 published Client Library API. Defined also private message key
6796 API and channel private key API into the file.
6798 This is the file that the application must include from the
6799 SILC Client Library. Other files need not be included by
6800 the application anymore.
6802 * Added new key_agreement client operation callback and also
6803 defined the Key Agreement library API for the application.
6805 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6808 is used by clients to request key negotiation between another
6809 client in the SILC network. If the negotiation is started it
6810 is performed using the SKE protocol. The result of the
6811 negotiation, the secret key material, can be used for example
6812 as private message key.
6814 Implemented the Key Agreement payload into the files
6815 lib/silccore/silauth.[ch].
6817 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Redefined ciphers for the SILC protocol. Added some new ciphers
6820 and defined the key lengths for the algorithms. Changed the
6821 code accordingly. The default key length is now 256 bits.
6823 * Fixed SKE key distribution function silc_ske_process_key_material
6824 when the key length is more than 128 bits. The default key
6825 length in SILC is now 256 bits.
6827 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6828 to indicate unsupported algorithm.
6830 * Renamed rijndael.c to aes.c and all functions as well.
6832 * Fixed a long standing channel key setting bug in client library.
6833 Weird that it has never surfaced before.
6835 * Fixed bug in channel deletion. If the entire channel is removed
6836 then it must also delete the references of the channel entry
6837 from the client's channel list as the client's channel entry and
6838 the channel's client entry share same memory.
6840 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Implemented CONNECT and SHUTDOWN commands in the client.
6844 * Implemented CLOSE command to the client.
6846 * Added the function silc_idlist_find_server_by_name into the
6847 files silcd/idlist.[ch].
6849 Added the function silc_idlist_find_server_by_conn into the
6850 files silcd/idlist.[ch].
6852 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * DIE command was renamed to SHUTDOWN. Updated the both code
6857 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6858 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6860 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6863 * Added function silc_server_create_connection function to create
6864 connection to remote router. My server implementation actually
6865 does not allow router to connect to normal server (it expects
6866 that normal server always initiates the connection to the router)
6867 so the CONNECT command is only good for connecting to another
6870 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6873 or some other client was kicked from the channel.
6875 Implemented the handling of the notify type to both client
6878 Implemented silc_server_send_notify_kicked to send the KICKED
6879 notify. It is used to send it to the server's primary router.
6881 * Implemented the KICK command into server and client.
6883 * Added `query' argument to the silc_idlist_get_client function
6884 to indicate whether to query the client from server or not if
6887 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6888 to indicate that the client is not channel founder.
6892 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6894 * Removed the rng context from SilcPacketContext structure and
6895 changed that the packet routine uses the Global RNG API.
6897 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Added support for quit message that client can "leave" on the
6900 channel when it quits the SILC. It is ditributed inside the
6901 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6903 Added silc_server_free_client_data that will take the
6904 signoff message as argument.
6906 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6908 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Updated parts of the protocol specification to keep it up
6913 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6916 payloads in one packet.
6918 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6919 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6920 use now the new List flag.
6922 * Also deprecated the following packet types: REPLACE_ID,
6923 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6925 * Added list support for Notify packet in server.
6927 * Added silc_server_send_notify_channel_change to send the
6928 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6929 the silc_server_send_replace_id.
6931 * Added silc_server_send_notify_nick_change to send the
6932 NICK_CHANGE notify type. Deprecates the function
6933 silc_server_send_replace_id.
6935 * Added silc_server_send_notify_join to send the JOIN notify type.
6936 Deprecates the function silc_server_send_new_channel_user.
6938 * Added silc_server_send_notify_leave to send LEAVE notify type.
6939 Deprecates the function silc_server_send_remove_channel_user.
6941 * Added silc_server_send_notify_cmode and
6942 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6943 types. Deprecates the silc_server_send_set_mode function.
6945 * Added SERVER_SIGNOFF notify type to indicate that server has
6946 quit. This means that all clients on the channel from that
6947 server will drop. This can be also used when netsplit happens.
6949 Deprecated REMOVE_ID packet type since it is not needed anymore
6952 Added silc_server_send_notify_server_signoff to send the
6953 SERVER_SIGNOFF notify type. Deprecates the function
6954 silc_server_send_remove_id.
6956 Added also silc_server_send_notify_signoff to send the
6957 SIGNOFF notify type.
6959 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6960 SILC protocol from this day on. Changed the protocol
6961 specification as well.
6963 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6964 notify type. It is used between routers to notify about
6965 topic changes on a channel.
6967 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6970 * Partly updated the protocol specification to comply with the
6971 changes now made. It is still though a bit outdated.
6973 * The JOIN notify type now takes one extra argument <Channel ID>.
6974 The packet used to be destined to the channel but now the
6975 JOIN type may be sent as list thus it is impossible to
6976 destine it to any specific channel. By adding this argument
6977 it is again possible.
6979 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Added CREDITS file. The CHANGES and CREDITS file will appear
6982 in the distribution as well.
6984 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6987 types in the server's silcd/packet_receive.c.
6989 * Implemented CMODE and CUMODE to work in router environment.
6991 * Fixed minor encoding and decoding buglet from the
6992 lib/silccore/silcmode.c.
6994 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6997 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6999 * Changed all SilcConfigServer* and silc_config_server* to
7000 SilcServerConfig* and silc_server_config*, respectively.
7003 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Associated the ID (client or server ID) to the Authentication
7006 Payload to avoid any possibility of forging. Updated the
7007 protocol specification and the code accordingly.
7009 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * The RSA key length is now save to the RsaKey context in the
7012 key generation process in lib/silccrypt/rsa.c. The key length
7013 is now used to figure out the maximum size of the block allowed
7014 to be encrypted/signed.
7016 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7017 is equivalent to the silc_mp_mp2bin but does not allocate any
7020 * Changed silc_mp_mp2bin API to take length argument. If it is
7021 non-zero then the buffer is allocated that large. If zero, then
7022 the size is approximated using silc_mp_sizeinbase, which however
7025 * Created Global RNG API which is global RNG that application can
7026 initialize. After initializing, any routine anywhere in the
7027 code (including library) can use RNG without allocating a new
7028 RNG object. This was done to allow this sort of use of the
7029 RNG in code that has no chance to allocate RNG object. All
7030 applications currently allocate this and many routines in the
7031 library use this. Affected file lib/silccrypt/silcrng.[ch].
7033 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7034 it to use the Global RNG API.
7036 * Defined Authentication Payload into protocol specification that
7037 is used during SILC session to authenticate entities. It is
7038 used for example by client to authenticate itself to the server
7039 to obtain server operator privileges.
7041 Implemented this payload into the lib/silccore/silcauth.[ch].
7042 Implemented also routines for public key based authentication
7043 as the new protocol specification dictates.
7045 Moved definitions of different authentication methods from
7046 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7048 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7049 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7050 silc_pkcs_verify_with_hash functions into the file
7051 lib/silccrypt/silcpkcs.[ch].
7053 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * The client entry's userinfo pointer must be always valid.
7056 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7057 will fail since it requires the userinfo. Now, the userinfo
7058 is allocated as "" if actual userinfo does not exist. Actually,
7059 it must exist and it is totally Ok to drop client connections
7060 that does not announce the userinfo. However, we will make
7061 this workaround for now.
7063 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7064 to return the remote port by socket.
7066 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7069 SILC_SERVER_PENDING_EXEC and added an new macro
7070 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7071 data or when error occurs while processing the pending command.
7073 Added new argument `destructor' into silc_server_command_pending
7074 and to the SilcServerCommandPending object. This destructor is
7075 now called after calling the pending callback or if error occurs
7076 immediately. If error occurs the actual pending callback won't
7077 be called at all - only the destructor. The destructor may be
7078 NULL if destructor is not needed.
7080 All this applies for client library code as well. Similar
7081 changes were made there as well for the pending commands.
7083 In the client, the application must now allocate the
7084 SilcClientCommandContext with the silc_client_command_alloc
7087 * Added reference counter to the SilcServerCommandContext. Added
7088 function silc_server_command_alloc and silc_server_command_dup
7091 Same type of functions added to the client library for the same
7094 * Removed the cmd_ident from IDListData away since it is now
7095 global for all connections. It is the command identifier used
7096 in command sending and with pending commands. The affected file
7099 * Added reference counter to the SilcSocketConnection objecet to
7100 indicate the usage count of the object. The object won't be
7101 freed untill the reference counter hits zero. Currently only
7102 server uses this, and client ignores it. The client must be
7103 set to use this too later. The affected files are
7104 lib/silccore/silcsockconn.[ch]. Added also the function
7105 silc_socket_dup to increase the reference counter.
7107 This was mainly added because it is possible that the socket
7108 is removed underneath of pending command or other async
7109 operation. Now it won't be free'd and proper DISCONNECTING
7110 flags, etc. can be set to avoid sending data to connection that
7111 is not valid anymore.
7113 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7114 the connection. After that it sets SILC_SET_DISCONNECTED.
7115 It is, however, possible that the socket data is not still freed.
7116 The silc_server_packet_process now checks that data is not
7117 read or written to connection that is DISCONNECTED. The socket
7118 get's freed when the reference counter hits zero.
7120 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Changed the client operation API: channel_message operation's
7123 `sender' is now the client entry of the sender, not the nickname
7124 and the `channel' is the channel entry, not the channel name.
7126 In the private_message operation the `sender' is now also the
7127 client entry of the sender not the nickname.
7129 Affected file is lib/silcclient/ops.h and all applications
7130 using the client operations.
7132 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Moved the calling of ops->connect() from connect_to_server_final
7135 into receive_new_id functin since that is the point when the
7136 client is actually allowed to send traffic to network. The
7137 affected file is lib/silcclient/client.c.
7139 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7142 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7143 (if needs broadcasting) instead of broadcasting the packets one
7144 by one which would make a burst in the network traffic.
7146 * Added `broadcast' argument to the functions in silcd/server.[ch]
7147 silc_server_create_new_channel[_with_id] to indicate whether
7148 to send New Channel packet to primary router.
7150 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Added new function into the silcd/server.[ch] files:
7153 silc_server_create_new_channel_with_id to create new channel with
7154 already existing Channel ID.
7156 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7157 lib/silccore/silcpacket.h. This packet is used t send list of
7158 Set Mode payloads inside one packet. Server uses this to set
7159 the modes for the channels and clients on those channels, that it
7160 announced to the router when it connected to it. The protocol
7161 specification has been updated accordingly.
7163 * The silc_server_new_channel did not handle the packet coming
7164 from normal server as it normally does not send that. However,
7165 when it announces its channels it does send it. Implemented
7166 the support for that.
7168 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7169 into the file lib/silccore/id.h.
7171 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Fixed memory leaks in the functions silc_idlist_del_client,
7174 silc_idlist_del_channel and silc_idlist_del_server in the file
7175 silcd/idlist.c. All of those leaked like a sieve.
7177 * Fixed some small memory leaks in the client's function
7178 silc_client_notify_by_server.
7180 * Added functions into silcd/server.c: silc_server_announce_clients,
7181 silc_server_announce_channels and silc_server_announce_server.
7182 These functions are used by normal and router server to announce
7183 to its primary router about clients, channels and servers (when
7184 router) that we own. This is done after we've connected to the
7187 These functions effectively implements the following packet types:
7188 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7189 and SILC_PACKET_NEW_ID_LIST.
7191 * Added new functions into the silcd/packet_receive.[ch]:
7192 silc_server_new_id_list, silc_server_new_channel_list and
7193 silc_server_new_channel_user_list to handle the incoming
7194 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7196 * Added support of changing Channel ID in the function
7197 silc_server_replace_id. If the server that announces a channel
7198 to the router already exists in the router (with same name but
7199 with different Channel ID), router is responsible to send
7200 Replace ID packet to the server and force the server to change
7201 the Channel ID to the one router has.
7203 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7204 client that the Channel ID has been changed by the router. The
7205 normal server sends this to the client. Client must start using
7206 the new Channel ID as the channel's ID.
7208 Implemented handling of this new type into lib/silcclient/client.c
7209 into the function silc_client_notify_by_server.
7211 * Added new function silc_idlist_replace_channel_id into the files
7212 silcd/idlist.[ch] to replace the Channel ID.
7214 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Call silc_server_command_identify_check always when processing
7217 the IDENTIFY command in silcd/command.c
7219 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7221 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7222 send keepalive packets. The packet can be sent by clients,
7223 servers and routers.
7225 Added function silc_socket_set_heartbeat into the file
7226 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7227 If not set, the heartbeat is not performed. The actual
7228 heartbeat is implemented in the low level socket connection
7229 library. However, application is responsible of actually
7232 Added silc_server_send_heartbeat to send the actual heartbeat
7233 packet into silcd/packet_send.[ch]. Server now performs
7234 keepalive with all connections.
7236 * Added silc_task_get_first function into lib/silcutil/silctask.c
7237 to return the timeout task with shortest timeout. There was a bug
7238 in task unregistration that caused problems. TODO has been
7239 updated to include that task system must be rewritten.
7241 * The client library will now resolve the client information when
7242 receiving JOIN notify from server for client that we know but
7243 have incomplete information.
7245 * Rewrote parts of silc_server_remove_from_channels and
7246 silc_server_remove_from_one_channel as they did not remove the
7247 channel in some circumstances even though they should've.
7249 * Encryption problem encountered in server:
7251 The LEAVE command used to send the Channel Key packet to the
7252 router immediately after generating it. However, the code
7253 had earlier sent Remove Channel user packet but not immediately,
7254 ie. it was put to queue. The order of packets in the router
7255 was that Channel Key packet was first and Remove Channel User
7256 packet was second, even though they were encrypted in the
7257 reverse order. For this reason, MAC check failed. Now, this
7258 is fixed by not sending the Channel Key packet immediately but
7259 putting it to queue. However, this is more fundamental problem:
7260 packets that are in queue should actually not be encrypted
7261 because packets that are sent immediately gets encrypted
7262 actually with wrong IV (and thus MAC check fails). So, packets
7263 that are in queue should be encrypted when they are sent to
7264 the wire and not when they put to the queue.
7266 However, the problem is that the current system has not been
7267 designed to work that way. Instead, the packet is encrypted
7268 as soon as possible and left to the queue. The queue is then
7269 just purged into wire. There won't be any fixes for this
7270 any time soon. So, the current semantic for packet sending
7273 o If you send packet to remote host and do not force the send
7274 (the packet will be in queue) then all subsequent packets to the
7275 same remote host must also be put to the queue. Only after the
7276 queue has been purged is it safe again to force the packet
7279 o If you send all packets immediately then it safe to send
7280 any of subsequent packets through the queue, however, after
7281 the first packet is put to queue then any subsequent packets
7282 must also be put to the queue.
7284 Follow these rules and everything works fine.
7286 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Added new function silc_server_remove_clients_by_server to
7289 remove all client entries from ID list when the server connection
7290 is lost. In this case it is also important to invalidate all
7291 client entires as they hold the invalid server entry. This
7292 fixes fatal bug when server has lost connection and will reconnect
7295 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7297 * Made some sanity checks to silc_server_daemonise like to check
7298 whether the requested user and group actually exists.
7300 * Added sanity check to SKE's silc_ske_responder_finish to check
7301 that the public and private key actually is valid.
7303 * Invalidate the client's nickname when receiving Replace ID
7304 packet and the Client ID is being replaced. This means that the
7305 server will query the nickname if someone needs it (client)
7308 * Sort the ID Cache in client library when the ID Cache data
7309 has changed (needs sorting).
7311 * Do not allow for SILC client to create several connections to
7312 several servers. The client does not support windows right now
7313 and generating multiple connections causes weird behaviour.
7315 Irssi-silc client does support windows and can handle several
7316 connections without problems, see: www.irssi.org and SILC plugin.
7318 * Fixed some places where client was added to the IDList. The
7319 rule of thumb is following (in order to get everything right):
7320 If the client is directly connected local client then the
7321 `connection' argument must be set and `router' argument must be
7322 NULL to silc_idlist_add_client function. If the client is not
7323 directly connected client then the `router' argument must
7324 bet set and the `connection' argument must be NULL to the
7325 silc_idlist_add_client function.
7327 * The funtion silc_server_packet_send_local_channel actually did
7328 not check whether the client was locally connected or not. It
7329 does that now. Fixed a bug related to LEAVE command.
7331 * Fixed Remove Channel User payload parsing bug in server's
7332 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7334 * The server's silc_server_save_channel_key now checks also the
7335 global ID list for the channel as it might not be in the local
7336 list. Fixed a bug related to LEAVE command.
7338 * Is this the end of the [<unknown>] buglet that has been lurking
7339 around for a long time? A little for loop fix in server's
7340 silc_server_command_whois_parse that is used by both IDENTIFY
7341 and WHOIS command. At least, this was a clear bug and a cause
7342 of one type of [<unknown>] buglet.
7344 * WHOIS and IDENTIFY commands call the function
7345 silc_server_command_[whois/identify]_check function even if
7346 we are not router server.
7348 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Added --with-gmp configuration option. If set the GMP
7351 is always compiled in the SILC source tree. If not set then
7352 it is checked whether the system has the GMP3 installed. If
7353 it has then the GMP won't be compiled (the system's headers
7354 and library is used), if it doesn't have it then the GMP is
7355 compiled in the SILC source tree.
7357 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * Changed RSA private exponent generation to what PKCS #1
7360 suggests. We try to find the smallest possible d by doing
7361 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7362 not security fix but optimization.
7364 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Added new config entry [Identity] to fork the server and run
7367 it as specific user and group. A patch from Bostik.
7369 * Imported Dotconf configuration library into lib/dotconf.
7370 This will be used to create the SILC configuration files later.
7371 It will appear in the distsribution after this commit.
7373 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * A big code auditing weekend happening. Auditing code for
7376 obvious mistakes, bugs and errors. Also, removing any code
7379 Removed files for being obsolete:
7381 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7382 inline in the file lib/silcutil/silcbuffer.h)
7384 o lib/silcutil/silcbufutil.c (the header has inline versions)
7386 Changed code to fix possible error conditions:
7388 o The buffer formatting routines now check that the destination
7389 buffer really has enough space to add the data. This applies for
7390 both buffer formatting and unformatting
7391 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7392 unformatting was changed to accomodate following rules:
7393 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7394 sent to the function while XXX_*STRING will not allocate or copy
7395 the data into the buffer. Instead it sets the pointer from the
7396 buffer into the pointer sent as argument (XXX_*STRING used to
7397 require that the pointer must be allocated already). This change
7398 makes this whole thing a bit more consistent and more optimized
7399 (note that the data returned in the unformatting with XXX_*STRING
7400 must not be freed now). The routines return now -1 on error.
7402 o Tried to find all code that use buffer_format and buffer_unformat
7403 and added return value checking to prevent formatting and
7404 especially unformatting errors and possible subsequent fatal
7407 o Changed ske->x and ske->KEY to mallocated pointers in
7408 lib/silcske/silcske.h. Fixed possible data and memory leak.
7410 o Added return value checking to all *_parse* functions. Fixed
7411 many memory leaks as well.
7413 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7414 so that buffer overflows would not happen. All code now also
7415 checks the return value as it can fail.
7417 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Added reconnection support to server if the normal server looses
7420 its connection to the router (for example if router is rebooted).
7421 The server performs normal reconnection strategy implemented
7422 to the server. Affected file silcd/server.c.
7424 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7426 * Added new packet type SILC_PACKET_SET_MODE that is used to
7427 distribute the information about changed modes (for clients,
7428 channels and clients channel modes) to all routers in the
7429 network. Updated the protocol specification accordingly.
7431 Added functions into silcd/packet_send.c and
7432 silcd/packet_receive.c: silc_server_send_set_mode,
7433 silc_server_set_mode.
7435 Added new files silcmode.[ch] into lib/silccore that implements
7436 the encoding and decoding of Set Mode Payload. Added new type
7437 SilcSetModePayload. Moved the definitions of different modes
7438 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7440 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Oops, a little mistake in server's connection authentication
7443 protocol. The protocol is not ended with FAILURE but with
7444 SUCCESS if the authentication is Ok. :) Affected file is
7447 * Implemented NICK_CHANGE notify handling in server in the file
7448 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7449 the local clients on the channel. After the changing nickname
7450 in router environment snhould work and the [<unknown>] nickname
7451 should appear no more.
7453 The silc_server_replace_id function that receives the Replace ID
7454 payload now sends the NICK_CHANGE notify type also in the file
7455 silcd/packet_receive.c
7457 * Changed WHOIS and IDENTIFY command to support the maximum amount
7458 of arguments defined in protocol specs (3328 arguments). This
7459 fixed a bug that caused problems when there were more than three
7462 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Added extra parameter, command identifier, to the
7465 silc_client_send_command so that explicit command identifier
7468 Changed that ID list routines uses specific command identifier
7469 when sending WHOIS/IDENTIFY requests to the server so that they
7470 can be identified when the reply comes back.
7472 Affected files lib/silcclient/command.[ch],
7473 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7475 * Added `sender' argument to silc_server_packet_send_to_channel
7476 to indicaet the sender who originally sent the packet to us
7477 that we are now re-sending. Ignored if NULL. Affected file
7478 silcd/packet_send.[ch].
7480 * Added some server statistics support in silcd/server_internal.h
7481 SilcServerStatistics structure and around the server code. Also
7482 send some nice statistics information when client is connecting
7485 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Fixed channel ID decoding in server's JOIN command reply in
7488 silcd/command_reply.c
7490 * Fixed braodcasting of replace ID payload to not to send it if
7491 we are standalone server in silcd/packet_receive.c.
7493 * Fixed all channel message sending routines to not to send
7494 packets to clients that has router set, since they are routed
7495 separately in the same function earlier. Affects file
7496 silcd/packet_send.c and all channel packet sending functions.
7498 * In USERS reply, res_argv[i] are not allocated, the table
7499 is allocated. Thus changed that free the table, not its
7502 * In server's whois_check and identify_check if the client is
7503 locally connected do not send any WHOIS commands - they are not
7506 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Fixed some minor bugs in client when sending WHOIS command. The
7509 arguments was in wrong order.
7511 * Removed statis function add_to_channel from server in
7512 silcd/command.c that was previously used with the joining but
7515 * Tested USERS command in router environment successfully with two
7516 routers, two servers and two clients.
7518 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Reorganized the USERS command and command reply in client library
7521 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7522 When the command is given by user we register a pending command
7523 callback that will reprocess the command after the reply has been
7524 received from the server. When reprocessing the packet we then
7525 display the information. Thus, the USERS information is displayed
7526 now in the command callback instead of in the command reply
7527 callback. The processing of the command is same as previously
7528 when server has sent the command reply in the JOINing process.
7530 * Added to USERS command in silcd/command_reply.c to join the client,
7531 we didn't use to know about, to the channel after we've created
7532 a client entry for it. Also, for clienet we did know already still
7533 check whether it is on the channel or not and add it if not.
7535 * Removed silc_server_command_join_notify as the function and its
7538 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Changed the client's pending command handling to the same as the
7541 server's pending command handling. It is also now possible to
7542 execute command reply functions from other command reply
7543 function as the function callbacks for commands and command
7544 replies are one and same. The pending commands are not static
7545 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7546 in client connection context. Thus, pending commands are server
7547 connection specific as it is convenient.
7549 Changed the function silc_client_command_pending and
7550 silc_client_command_pending_del and added new function
7551 silc_client_command_pending_check. Removed the
7552 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7555 * Added cmd_ident, current command identifier, to the client
7556 connection context in lib/silcclient/client.h to keep track on
7557 command identifiers used in command sending. Client's command reply
7558 function handling now supports the mandatory command identifiers.
7560 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7561 funtions in client to fully support pending command callbacks.
7563 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7564 as one of the arguments to the application in the command reply
7567 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7568 before first releasing SILC but came back. Now it is removed again
7569 and should come back nomore. The FORWARDED flag was used only
7570 by the JOINing procedure by forwarding the command packet to router.
7571 Now, the JOINing procedure has been changed to more generic (due
7572 to various router environment issues) and FORWARDED is not needed
7573 anymore for anything. The protocol specification is yet to be
7576 Now, removed silc_server_packet_forward from server and the flag
7577 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7579 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7581 * Renamed NAMES command to USERS command. The NAMES was named that
7582 due to historical reasons. Now it is renamed. Also, rewrote
7583 parts of the USERS command. The nickname list is not sent anymore
7584 by the server. Only Client ID and mode lists are sent in the USERS
7585 command. Changed this also to the protocol specification.
7587 The client now resolves the names and stuff after it receives
7588 the USERS list from the server when joining to the channel.
7590 * WHOIS and IDENTIFY commands has been changed to support multiple
7591 Client ID's per command. One can now search for multiple users
7592 in the network by sending only one WHOIS or IDENTIFY command.
7593 Changed the code and the protocol specifications.
7595 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7596 uses silc_server_command_whois_parse to parse the request. */
7598 * If normal server, do not parse the WHOIS and IDENTIFY requests
7599 before sending it to the router. Saves some time.
7601 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7603 * Fixed JOIN command on client library. Wrong number of arguments
7604 used to crash the client.
7606 * Added silc_server_channel_has_global function to check whether
7607 channel has global users or not.
7609 * Added silc_server_channel_has_local function to check whether channel
7610 has locally connected clients on the channel.
7612 * The silc_server_remove_from_one_channel now checks whether the
7613 channel has global users or not after given client was removed from
7614 the channel. It also checks whether the channel has local clients
7615 on the channel anymore. If it does not have then the channel entry
7616 is removed as it is not needed anymore.
7618 * The silc_server_notify now checks on JOIN notify whether the joining
7619 client is one of locally connected or global. If it is global then
7620 the channel has now global users on the channel and that is marked
7621 to the channel entry. Also, it now saves the global client to
7622 global list who is joining and JOINs it to the channel. This is
7623 for normal server, that is.
7625 Changed silc_server_send_notify_on_channel,
7626 silc_server_packet_relay_to_channel and
7627 silc_server_packet_send_to_channel check if we are normal server
7628 and client has router set (ie. global client) do not send the
7629 message to that client, as it is already routed to our router.
7631 * Implemented LEAVE notify type handling in silc_server_notify
7634 * Tested LEAVE command in router environment successfully. Tested
7635 with two routers, two servers and two clients.
7639 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7641 * Implemented SIGNOFF notify type handling in silc_server_notify
7644 * silc_server_remove_id now removes the client entry from all channels
7645 it has joined and thusly sends SIGNOFF notify type.
7647 * Rewrote the NAMES list generation in server by removing two excess
7648 loops. The lists are created now inside one loop.
7650 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7652 * silc_server_remove_channel_user checks now also global list
7653 for channel and client.
7655 * silc_server_new_channel_user checks now both local and global
7656 list for channel and client. Fixed a bug in client id decoding.
7657 Used to decode wrong buffer.
7659 * silc_server_channel_message checks now both local and global
7660 list for channel entry.
7662 * Tested channel joining (hence JOIN) in router environment
7663 successfully. Tested with two routers, two servers and two
7666 * Tested channel message sending in router environment successfully.
7668 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7670 * Added silc_server_save_channel_key into server.[ch] to save the
7671 received channel key in Channel Key payload processing. It is
7672 also used in JOIN command reply handling.
7674 Equivalent function silc_client_save_channel_key added into
7675 client.[ch] into client library.
7677 * Changed JOIN command reply to send information whether the channel
7678 was created or not (is existing already) and the channel key
7679 payload. Changed protocol specs accordingly.
7681 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7682 the request was sent by ID and not by nickname. Crashed on
7685 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7688 now correctly save the received data.
7690 * silc_server_free_sock_user_data now notifies routers in the
7691 network about entities leaving the network.
7693 At the same time implemented functions silc_server_remove_id
7694 and silc_server_send_remove_id to receive and send REMOVE_ID
7695 packets. The packet is used to notify routers in the network
7696 about leaving entities. The ID removed will become invalid in
7699 * Added function silc_idlist_del_server into server. Removes and
7700 free's server entry from ID list.
7702 * silc_server_private_message function now checks, if we are router,
7703 that the destination ID really is valid ID, naturally.
7705 * In router when NEW_ID packet is received (for new client) the
7706 hash of the Client ID is saved in the ID Cache but the
7707 client->nickname is set to NULL, instead of putting the hash
7710 IDENTIFY command now also checks that client->nickname must be
7711 valid. If it is not if will request the data from the server who
7712 owns the client. Added new function
7713 silc_server_command_identify_check.
7715 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7716 to set the command to already allocated Command Payload.
7718 * Tested private message sending in router environment with two
7719 routers, two servers and two clients. Fixed minor bugs and now
7722 * Fixed segfault from client's NAMES command. Used to crash if
7725 * Forwarded packets must not be routed even if it is not destined
7726 to the receiver. Changed server code comply with this.
7728 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Added `require_reverse_mapping' boolean value to ServerParams
7731 structure. If TRUE (not default) the server will require that
7732 the connecting host has fully qualified domain name.
7734 If the reverse mapping is not required and hostname could not be
7735 found the IP address is used as hostname.
7737 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Implemented version string checking to both client and server.
7740 The check is incomplete currently due to the abnormal version
7741 strings used in development version of SILC.
7743 * Changed all command functions in server to use the new
7746 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Changed char *data to unsigned char *data in ID Cache system to
7749 support binary data as ID Cache data. Changed code to support
7750 binary data in lib/silccore/idcache.c.
7752 * Renamed silc_server_packet_relay_command_reply to
7753 silc_server_command_reply as it is normal packet receiving
7754 function. Rewrote the function to accept command replys for
7755 servers and not only for clients.
7757 * Mark remote router always as registered server if we are connecting
7758 to it. Otherwise, commands sent by the router to us are ignored.
7760 * All ID List find routines now returns the ID Cache Entry pointer
7761 as well if requested.
7763 * WHOIS command works now in router environment, tested with two
7764 routers, two servers and two clients.
7766 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7767 in router environment (as it is almost equivalent to WHOIS) but
7768 hasn't been tested thoroughly. Added new functions:
7770 silc_server_command_identify_parse
7771 silc_server_command_identify_send_reply
7772 silc_server_command_identify_from_client
7773 silc_server_command_identify_from_server
7775 * Disabled route cache adding because adding two different ID's with
7776 same IP replaces the old cache entry thus giving wrong route.
7777 The entry->router->connection is always the fastest route anyway
7778 so route cache may not be needed. Of course, new routes maybe
7779 established after receiving the ID when the entry->router->connection
7780 might not be anymore the most optimal.
7782 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Add route cache for received ID for fast routing.
7786 * Added silc_server_packet_route to route received packet on router
7787 that is not destined to us.
7789 * Renamed silc_server_get_route to silc_server_route_get.
7791 * Added id_string and id_string_len fields into SilcServer to
7792 include encoded ServerID for fast comparing without excess
7793 encoding of the ID's.
7795 * Cleaned up WHOIS command on server side. Added following static
7798 silc_server_command_whois_parse
7799 silc_server_command_whois_check
7800 silc_server_command_whois_send_reply
7801 silc_server_command_whois_from_client
7802 silc_server_command_whois_from_server
7804 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7805 arguments in command replies. All command functions should be
7806 updated to use this macro.
7808 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * Minor typo fixes on command reply handling on server.
7812 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * Added silc_server_command_add_to_channel internal routine to add
7815 the client to the channel after router has created the channel and
7816 sent command reply to the server.
7818 * Added generic silc_server_send_command to send any command from
7821 * Use static buffer with ID rendering instead of duplicating data.
7823 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Fixed a channel user mode bug when joining to a channel server gave
7826 everybody channel founder rights, oops.
7828 * We mark ourselves as the router of the incoming server connection
7829 if we are router ourselves. This way we can check in some packet
7830 sending functions whether it is locally connected server. For
7831 incoming router connections we put NULL.
7833 * For router sending packets locally means now always sending the
7834 packet cell wide; to local clients and local servers. For normal
7835 server sending packet locally means sending it to only local
7838 * Fixed the JOIN command to really work in router environment. If the
7839 channel is created it is always created by the router. Router is
7840 also responsible of making the initial joining to the channel,
7841 sending JOIN notify to the sending server and distributing
7842 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7843 does not exist server doesn't do anything else but forward the
7844 command to the router which performs everything.
7846 * Added silc_server_send_channel_key function to send the Channel Key
7849 * Added silc_server_create_channel_key to create new channel key. The
7850 channel key is now re-generated everytime someone joins or leaves
7851 a channel, as protocol dictates. Note: channel->key_len is the
7854 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7857 packet_receive.[ch] to separate packet sending and receiving
7858 routines. The server.[ch] now includes everything else including
7859 actual packet processing (writing and reading data) and other
7862 Renamed silc_server_private_message_send_internal to
7863 silc_server_send_private_message. The routine is still though
7864 used only to relay private messages as server does not send
7865 private messages itself.
7867 Renamed silc_server_new_channel to silc_server_create_new_channel
7868 and added new function sicl_server_new_channel that handles the
7869 incoming New Channel packet. Added also new sending function
7870 silc_server_send_new_channel to send New Channel Payload.
7872 * Added new function silc_server_notify to process incoming notify
7873 packet to the server/router. Server may then relay the notify
7874 to clients if needed.
7876 * Added new function silc_server_new_channel_user to process incoming
7877 New Channel User packet. Router will redistribute the packet and
7878 send JOIN notify to its local clients and locally connected servers
7879 if needed. Normal server will send JOIN notify to its local client
7880 on same channel when received this packet. Added also corresponding
7881 sending function silc_server_send_new_channel_user to sent the
7884 * Added boolean route argument to send_notif_to_channel and
7885 packet_send_to_channel functions to attempt to route the packet
7886 if it is TRUE and send only locally if it is FALSE.
7888 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * silc_server_replace_id now broadcasts the received replace ID
7891 packet if it is not broadcast packet already. The router must
7892 broadcast to inform other routers about changed ID.
7894 * Added backpointer to server's router into SilcServer context in
7895 silcd/server_internal.h.
7897 * Fixed silc_server_packet_broadcast to send correct broadcast
7900 * The channel key is now distributed to the local client as soon
7901 as it is received from the router (in router environment) so that
7902 no other packet may be sent for the channel until client has
7905 * silc_server_remove_channel_user now broadcasts the received
7906 Remove Channel User packet if it is not broadcast packet already.
7907 The router must broadcast to inform other routers about removed
7910 * Added users field into SilcPacketContext that is a reference count
7911 of the context. One can increase the reference count by calling
7912 silc_packet_context_dup which is now changed to just increase the
7913 reference count instead of duplicating the data. The reference
7914 count is decresed by calling silc_packet_context_free that will
7915 free the data after the reference count hits zero.
7917 For now on the packet context and everything allocated into it
7918 (including the raw packet from network) must be freed by calling
7919 the new silc_packet_context_free function. Added also new function
7920 silc_packet_context_alloc that must be used now to allocate the
7921 context. This also means that if a routine is asynchronous from
7922 silc_[client/server]_packet_parse_type the packet context must
7923 be duplicated by calling silc_packet_context_dup. Otherwise it
7924 gets free'd after silc_[client/server]_packet_parse_type returns.
7925 Also, one must remember that if packet is duplicated then its
7926 reference count must be decresed by calling the free function as
7927 many times as it was duplicated.
7929 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7930 from both client and server.
7932 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7934 * Made joining to a channel working in router environment.
7936 * Cleaned up JOIN command on server side and create function
7937 silc_server_command_join_channel internal routine to make the
7940 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7942 * Changed silc_command_pending list to SilcDList. Also, added
7943 `ident' field to SilcServerCommandPending structure to identify
7944 the reply and to call correct callback.
7946 Added silc_server_command_pending_check function to replace the
7947 corresnponding macro. The silc_command_pending list is not
7950 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7951 to set identifier to previously allocated Command Payload. It
7952 is used to set identifier for command when resending Command
7955 * Added silc_command_payload_encode_payload to encode Command
7956 Payload buffer from SilcCommandPayload structure.
7958 * Added silc_argument_payload_encode_payload to encode Argument
7959 payload buffer from SilcArgumentPayload structure.
7961 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Changed WHOIS command to support router connection on server side.
7964 The whois request is always sent to router unless the server is
7965 standalone server. After server has received the reply from the
7966 router will it send the reply to the client.
7968 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7969 broadcast received broadcast packet. The function is used only
7970 by router. The broadcast packet is always sent to the router's
7973 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7974 render given ID to printable string, for log files for example.
7976 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Made basic router to router connections working. At least they
7979 can now connect to each other but nothing really works the way
7980 they are supposed - yet.
7982 * Added new initiator token to RouterConnection configuration
7983 file in silcd/serverconfig.[ch]. It is used to tell whether we
7984 are the initiator to the remote router or whether we'll expect
7985 the other end to connect.
7987 * Moved registering of listener task to silc_server_init, hence
7988 the server starts listenning as soon as it is run, even if it
7989 does not have connections to other routers. Let's see how well
7992 * Changed default connection retry timeouts for more suitable in
7995 * Removed cipher and such arguments from silc_idlist_add_client
7996 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7997 Added new function silc_idlist_add_data to add the keys and stuff
8000 * Added SilcIDListData structure and added it to SilcClientEntry
8001 and SilcServerEntry as their first field in the structure. This
8002 way we can explicitly cast the ID entries to the SilcIDListData
8003 structure and get common data for the entries. In past, we had
8004 to first check what type of connection it is and then cast it to
8005 correct ID entry type. Now, we can directly cast the opaque
8006 pointer to the SilcIDListData (no matter what ID entry it actually
8007 is) and get the data needed.
8009 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8012 in some circumstances even if threre were timeout tasks, though not
8013 IO tasks, but tasks anyway. Now fixed.
8015 * Defined SilcServerConnection structure to hold connection specific
8016 stuff about directly connected servers and routers. The definition
8017 is currently in silcd/server_internal.h. I thought about having
8018 a bit more important role fro this struct but for now it is used
8019 only when connecting to other server (or router actually).
8021 * Added connecting retry support in server when connecting to
8022 router(s). The retry feature implement exponential backoff
8023 algorithm. Also, added SilcServerParams structure to hold default
8024 parameters for server. For now, it include these retry settings
8025 and are hard coded. After server is moded to be as Silc Server
8026 Library this structure will be more important.
8028 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * Changed client librarys channel->clients table to SilcList and
8031 changed code accordingly.
8033 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Changed client's channel table to SilcList and changed code
8036 accordingly. Also changed SilcChannelClientEntry to include back-
8037 pointer to the channel so that client entry can use that structure
8038 as list as well and we have fast cross-reference to the channel.
8039 This change dramatically decreased the complexity of channel
8040 handling with client entry and vice versa (removed one extra
8041 loop when searching for channel entry from many functions).
8043 * Changed server->sim from table to SilcDList and changed code
8046 * NAMES command can now be used from user interface. It will show
8047 the user list on the channel, neatly.
8049 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8050 Code now saves realname of the user if it becomes available.
8052 * Renamed configure.in to configure.in.pre and made ./prepare
8053 script to automatically add correct version string to
8054 configure.in which it creates from configure.in.pre.
8056 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * NAMES command reply now shows users mode with the nickname when
8061 * Moved silc_client_ch[u]mode[_char] functions from
8062 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8063 place sucks, they are utility functions and should be in some
8066 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8068 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8071 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Added TRQ (efficient deque and list library) into lib/trq. This is
8076 a very good list library that is currently used in the SILC. Defined
8077 SilcList API over the library because I didn't like the API very
8078 much. See lib/trq/silclist.h for the API and examples of how to
8079 use the API. Fixed various places in the code to use the new
8080 SilcList API. The SilcList is meant for lists that has a structure
8081 already defined as a list. It is not suitable to add just some
8082 context to the list (in TRQ, the context is the list actually).
8084 So, I defined SilcDList that can be used for the purpose where
8085 predefined list structure does not exit. This can be used as
8086 such list. Now some context just can be added to the SilcDList.
8087 Currently this list is not used in the SILC just yet, though there
8088 are a lot places where this can replace dynamically allocated
8089 tables and I will fix these places, later, to use SilcDList.
8090 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8091 and use TRQ internally).
8093 Also fixed some annoying warning messages that the original TRQ
8094 code generated. Also minor changes to TRQ's Makefile.in.
8096 * Added support for querying by Client ID to both WHOIS and
8097 IDENTIFY commands into server, as required by the protocol.
8099 * Removed method function pointers from SilcBuffer structure. They
8100 weren't used to anything and just increased the context size for
8101 no good reason. This change also made silc_buffer_alloc and
8102 silc_buffer_free functions inline functions.
8104 * Disabled command flooding detection support until it's fixed so
8105 that it accepts commands in but does not execute them more than once
8108 * Added silc_net_localhost(), to return local hostname, into
8109 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8110 that must be initialized before calling silc_client_init.
8112 * Added new function: silc_server_send_notify_on_channels to send
8113 notify messages to all channels client has joined. It is assured
8114 that the message is sent only once per client.
8116 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8117 lib/silcutil/silcutil.[ch] as silc_format function. The new
8118 function is generic and is used by server as well, not only by
8119 the logging routines.
8121 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8122 the provided version string was not acceptable. Added new function:
8123 silc_ske_check_version into lib/silcske/silcske.h. The function
8124 must be implemented by the application (client or server) and it
8125 does not reside in the SKE library. The function checks the version
8126 string remote end sent.
8128 * Added back pointers (to opaque context and to SilcSocketConnection)
8129 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8131 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8132 duplicate packet context structure.
8134 * Changed `notify' client operation to send same arguments as client
8135 receives from server except for ID's. ID's are mapped to correct
8136 ID entry and that is returned. Also, if channel entry is not sent
8137 by server but the notify is for channel the channel entry is sent
8138 to application (otherwise application doesn't know that it is for
8139 channel (library gets it from packet's Destination ID)).
8141 * Added silc_client_remove_from_channels into client library to
8142 remove a client from all channels it has joined to. Used when
8143 received SIGNOFF notify from server. Added also new function
8144 silc_client_replace_from_channels to replace old ID entry with
8145 new ID entry on all channels. Used when received NICK_CHANGE
8148 * Fixed ID Cache list handling in silc_idlist_get_client in
8149 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8150 to get (or query) client by ID.
8152 * Updated TODO list.
8154 * Added connection authentication status message defined by the
8155 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8156 support for these into the code in client and server side.
8158 * Added generic function silc_client_send_command to send any command
8159 with variable argument list. Application should use this function
8160 to send commands if the command functions provided by the library
8161 does not suite for the application's user interface needs.
8163 * Added new `failure' client operation. Application is notified about
8164 received failure packet if client is executing a protocol. In this
8165 case the protocol's execution has failed.
8167 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8168 is required by the protocol.
8170 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8171 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8174 * Added status flag to SilcSKE object to indicate realtime status
8175 of the SKE protocol.
8177 * Application receives now exactly same command reply arguments as
8178 the library receives from server. However, if ID is received the
8179 corresponding ID entry is returned to the application (eg. Client
8180 ID is mapped to correct SilcClientEntry entry and that is returned).
8181 Changed command_reply client operation due to this change.
8183 * Changed all ID's in commands and in command replys as ID Payloads.
8184 Change affected both client and server side codes.
8186 All ID's sent in SILC network (with execption of ID's in SILC
8187 Packet header) are sent in ID Payload to support variable length
8190 * Server now notifies nick changes and notifies all clients on
8191 the channels about the new nickname (about the new Client ID,
8194 * Implemented CMODE command to change channel modes. Supports all
8195 channel modes defined by the protocol specs except ban and invite
8196 lists. (Also, private channel key mode is supported but support for
8197 setting private channel key in client is missing, thus, this mode
8198 has no effect on client side (except that server requires that the
8199 client uses private channel key and normal channel traffic does not
8202 Also, invite mode works per se, but INVITE command does not work
8203 yet correctly, so you can set channel as invite only channel but
8204 inviting clients to the channel does not work (it is yet to be
8205 thought what's the best way to do it).
8207 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8208 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8209 Implemented CUMODE command to change user's mode on the channel.
8210 Supports all modes defined by the protocol specs.
8212 * Added NAMES command reply to return users modes on the channel.
8214 * Removed unnecessary and slow ciphers from lib/silccrypt.
8216 * Set SO_KEEPALIVE option to connection sockets by default.
8218 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8220 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8221 redefined the Notify Payload into protocol specs.
8223 * Added silc_id_payload_parse_id to get ID directly from raw
8226 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8228 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8229 accept searching by Client ID as well.
8231 * Added support for LEAVE and SIGNOFF notify types in client library.
8233 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8234 to parse ID Payload from raw data.
8236 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8238 * Added flags parameter into silc_ske_assemble_security_properties
8239 function in lib/silcske/silcske.[ch].
8241 * Changed notify client operation to fit better for notify messages
8242 sent by server. The notify payload received from server is now
8243 passed to the application (after parsing it to SilcNotifyPayload).
8244 It is application's responsibility to retrieve the arguments
8245 from the payload and show the message the way it wants. The message
8246 sent by server is implementation specific.
8248 * Changed public keys to comply with the protocol specification.
8249 Old public keys are not supported anymore and are not compatible.
8251 * Removed nickname from Channel Payload as the latest draft removed
8252 it. The client must resolve the nickname from the NAMES command
8253 reply received when it joined the channel.
8255 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8257 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Fixed some errors in protocol specification drafts.
8261 * Created lib/silccore/silcnotify.c to implement Notify Payload
8262 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8263 generic payloads described by protocol specifications. The file
8264 includes implementations for ID Payload and Argument Payload.
8266 * Changed Command Payload implementation to use the new Argument
8267 Payload. Changed command_xxxx_payload to command_payload_xxxx
8268 to comply with SILC coding conventions.
8270 * Added suppport for Argument Payload handling in Notify Payload
8271 implementation as protocol requires it. Added the new support
8272 into server and client lib as well.
8274 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8276 * Added support for multiple nicknames on same channel. [n] is
8277 added locally to the nickname if there are more than one same
8278 nicknames on the channel.
8280 * Server now sends all nicknames that matched WHOIS request.
8281 Client also shows the list received from server.
8283 * Added TOPIC command to client side. User can now set and show
8284 current topic on channel.
8286 * Added MOTD command to client and server. Also, server sends the
8287 motd when client connects to the server.
8289 * Changed version strings to comply ISO 8601.
8291 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Fixed protocol error handling in client library. It should now
8294 cope even if the SKE fails for some reason.
8296 * Made new protocol specification drafts for submitting to IETF.
8298 * Implemented TOPIC command to server in silcd/command.c.
8300 * Added two new notify types into lib/silccore/silcnotify.h:
8301 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8302 notify nickname change and topic setting/change on a channel.
8304 * API change of command_reply operation in client library. The
8305 application gets now the status type received from server as well.
8307 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8309 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8311 * Cras fixed and optimized the packet handling even further and
8312 it should work now. Minor change to the prototype of function
8313 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8315 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8317 * Added new function into lib/silcutil/silcschedule.[ch]:
8318 silc_schedule_with_fd to select() a specified fd. The function
8319 returns after timeout expires or data arrives or goes. The
8320 function is used by packet routines to wait that all data is
8321 received from network.
8323 * Fixed data reading from network in lib/silccore/silcpacket.c.
8324 The code now assures that all data is read from the fd and then
8325 continues packet processing. This was a bug fix since the code
8326 used to drop some data in some circumstances.
8328 * Added new function into lib/silcclient/client.[ch]:
8329 silc_client_start_key_exchange to start key exchange after
8330 connection has been established to server. The code internally
8331 now uses this funtion but its main purpose was to provide it
8332 for applications that perform their own connecting. After
8333 application has created a connection it merely calls this
8334 function to start the key exchange between client and server.
8335 The library takes care of everything else after that.
8337 Updated also lib/silcclient/README to explain the usage of
8340 * Do not send to application information that connection has
8341 been established. Application gets notified it by connect
8344 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8346 * Applied cras's patch to add silc_schedule_one function. The
8347 function runs scheduler once and returns.
8349 * Fixed the scheduler after cras messed it up. The timeout
8350 handling works now as it's supposed to work.
8352 * Added into lib/silccore/ silcnotify.h to include notify
8353 message types support. Changed silc_server_send_notify*
8354 functions, in server.[ch], to support those new notify types.
8355 Added the support for the notify types into client library,
8356 as well. Added new notify client operation into ops.h in
8359 * Changed silc_server_packet_send_to_channel to send normal
8360 packets instead of just channel message packets. The function
8361 is now used to send the notify packets to channels. It is not
8362 used to send channel message packets anymore, as server never
8365 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8366 va_arg()s as it seems to require it nowadays. I guess, if SILC
8367 is compiled with older va_arg() the new code should work anyway.
8369 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8371 * Splitted core library. Core library (lib/silccore) includes
8372 now only SILC protocol specific core (and common) components.
8373 Created new utility library (lib/silcutil) that includes more
8374 generic purpose stuff. The stuff for util library was taken
8375 from the old core library. This was minor and easy split.
8377 * Created SILC Client Library (lib/silcclient) that includes
8378 implementation of the SILC client without user interface. This
8379 was major move from silc/ directory. The code has been changed
8380 so that it is transparent towards the user interface. The
8381 silc/ directory includes now the same user interface as before
8382 and it uses the new client library. Read lib/silcclient/README.
8383 Basicly, the client library performs everything else related
8384 to SILC except user interface handling. Also, configuration
8385 files are considered to be part of user interface and library
8386 does not handle them.
8388 This change also changed a lot of structures, function naming etc.
8389 Most important change was that SilcClientWindow object was
8390 renamed to SilcClientConnection in the client library. Created
8391 also new file lib/silcclient/ops.h. Also added new files
8392 silc/local_command.[ch] and silc/client_ops.[ch].
8394 All these changes were made to make it easier for user interface
8395 designers to create what ever user interface for the SILC client
8398 It is also expected that the server will be moved to lib
8399 directory as well and SILC Server Library will be created;
8400 sometimes in the future.
8402 * Removed Local commands from lib/silccore/silccommand.h as
8403 they are application specific and new client library does not
8404 handle any of those anymore.
8406 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8407 old client implementation in silc/.
8409 * Added support for callback functions in SILC_LOG_* macros.
8410 Application can now set its own callbacks that will be called
8411 instead of using the default functions that will always print
8412 the debug messages to stderr (or stdout). Also, debugging can
8413 now be disabled by setting silc_debug to FALSE and re-enabled by
8414 setting it to TRUE. Note, that logging will still work even
8415 if debugging is disabled.
8417 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8418 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8419 silc_log_reset_debug_callbacks.
8421 * To enable debugging in silc client one must give now -d
8422 option on command line.
8424 * Changed silc_schedule_init to automatically allocate task queues
8425 if they are not allocated before calling it.
8427 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8429 * Added GMP 3.1 into math library.
8431 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8433 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8434 a channel in SILC network. The packet is used by servers and
8435 routers to notify other routers that user has left a channel.
8436 This little feature was missing until now. Added the feature
8437 to protocol specification as well.
8439 Added functions: silc_server_send_remove_channel_user and
8440 silc_server_remove_channel_user into server.[ch].
8442 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8443 lib/silccore/silcpacket.h. However, they are not implemented
8446 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8448 * Fixed joining to a channel and sending channel messages
8449 between server and router. The channel message sending should
8450 now work inside a cell.
8452 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Fixed the private message sending between server and router.
8455 The private message sending should now work inside a cell.
8457 * Added silc_server_replace_id into server.[ch] to replace
8458 existing ID in the SILC network.
8460 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8461 and silc_idlist_replace_server_id into idlist.[ch] in server.
8463 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8465 * Fixed the server to server connections. Server can again now
8466 connect to router. Router to router connections probably does
8469 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8471 * Added dynamic protocol registering support. Now protocols can
8472 registered and unregistered on the fly. Patch by cras.
8474 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8476 * Added lib/contrib directory to hold routines that some platforms
8477 don't have but are needed by SILC.
8479 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8480 into lin/contrib to provide getopt() and getopt_long() for
8481 those who don't have it.
8483 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8485 * Added AWAY command to client. When away message is set and
8486 client receives a private message packet the client automatically
8487 replies to the sender with the away message.
8489 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8490 bug seemed to be the cause of recent problems when compiling
8493 * Added version detection support to SKE protocol specification
8494 and added the new changes to the SKE implementation as well.
8495 There were other minor changes in the SKE protocol as well.
8497 Many changes in lib/silcske/silcske.[ch] and in
8498 lib/silcske/payload.[ch].
8500 * Added ^U functionality, clear input line. Patch from cras.
8502 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8504 * Mainly small bugfixes on core library. Fixed some debugging
8505 logging and buffer overflow in silclog.c.
8507 * Updated config.sub and config.guess on the distribution tree.
8509 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8511 * Added command lagging support in server. Client may execute
8512 commands now only once in two seconds.
8514 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8516 * Optimized packet reception. MAC computation and checking is now
8517 also more optimized. A lot previously duplicated code is now
8518 used as generic by both client and server.
8520 * Fixed key pair generation in clientutil.c
8522 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8524 * Added into lib/silccore/silcbufutil.[ch] new function;
8525 silc_buffer_realloc.
8527 * Moved generic packet sending/encryption functions to
8528 lib/silccore/silcpacket.[ch] from client and server. Some
8529 rewriting of the functions.
8531 * Moved all generic packet reception/decryption functions to
8532 lib/silccore/silcpacket.[ch] from client and server. The
8533 packet processing is now much cleaner in both client and server.
8534 These were major changes in both client and server.
8536 * Created many common functions in server to do packet sending.
8537 Previously code were duplicated a lot, this has been removed
8540 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8542 * Rewrote major parts of the ID cache system. Don't know
8543 whether it is better now or not but at least the API is more
8546 * Major rewrite on ID cache stuff on client because of the ID
8547 cache API changes. Added idlist.c to client.
8549 * Also major rewrite on ID cache stuff on server as well.
8550 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8551 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8552 in hand, instead they are all put into the ID cache system now.
8553 All server_idlist_* routines uses ID cache now instead of
8554 traversing its own lists (those lists does not exist anymore).
8555 SilcIDList though still exists. Also, SilcXXXEntry's are
8558 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8560 * Finally made the SKE implementation compliant to the protocol
8561 specification. All mp integers are now binary encoded as
8562 opposed being HEX encoded.
8564 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8567 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8568 functions: silc_[encode/decode]_pem. Also added function
8569 silc_encode_pem_file to PEM encode with newlines ('\n') for
8572 * SILC public keys are now encoded either PEM or binary. Same
8573 option is for private keys as well. By default private keys
8574 are binary encoded and public keys PEM encoded. Silly HEX
8575 encoding were removed.
8577 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8578 function to create fingerprints.
8580 * Fixed a bug in SHA1; does not change the original data anymore.
8582 * Partly implemented INFO command on client and server side.
8583 Fixed CLEAR command. Changes to SERVER command; show current
8584 server(s) when giving command without arguments. Added
8585 VERSION command to client.
8587 * Added check to server that unregistered connections cannot
8588 execute commands (unless it is specificly allowed).
8590 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8592 * Fixed screen refresh.
8594 * Fixed channel joining bug from client. On some circumstances
8595 client tried to join to a channel it had already joined.
8597 * Added public key verification process into client's protocol.c.
8598 The client now verifies the public key from user and saves
8599 it into ~./silc/serverkeys/ directory.
8601 Added into: clientutil.[ch]: silc_client_verify_server_key.
8603 * Changed SKE protocol's silc_ske_initiator_finish function
8604 to accept callback function that verifies the received public
8605 key. Removed old silc_ske_verify_public_key function.
8607 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8609 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8610 silc_pkcs_private_key[_data]_set.
8612 * Made the password and public authentication more cleaner in
8613 server's protocol.c.
8615 * Removed historic and obsolete protocol `channel_auth' from
8616 both client and server.
8618 * Removed wrong way of sending command status messages from
8619 server to client in server's command.c. The old way violated
8620 protocol specification.
8622 Changes to silccore/silccommand.[ch]: removed
8623 silc_command_encode_status_payload -> not needed anymore,
8624 changed silc_command_encode_payload_va to accept extra
8625 argument on variable argument list. The argument type must
8626 now be provided to the function. Also, added new function:
8627 silc_command_encode_reply_payload_va which is same as
8628 normal command_encode_payload_va except command status type
8629 is provided as extra argument.
8631 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8633 * Added ~./silc directory handling. The directory includes the
8634 public and private keys for the client.
8636 Added silc_client_check_silc_dir, silc_client_create_identifier
8637 and silc_client_load_keys.
8639 * Implemented SILC protocol compliant public key. Added public
8640 and private key saving to and loading from files.
8642 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8643 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8644 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8645 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8646 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8648 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8649 silc_pkcs_load_[public/private]_key.
8651 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8653 * Added silc_server_get_route (route.[ch]) to get connection
8654 data for the fastest route for given ID.
8656 * Implemented INVITE command on client and server. The command
8657 were re-defined in the SILC Protocol Specification and the
8658 implementation now complies with the specification.
8660 * Implemented PING command on client and server.
8662 * Implemented NAMES command on client and server. The server side
8663 supports currently only normal server not router server yet.
8664 Some changes to NAMES definition in SILC protocol specification.
8666 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8668 * Implemented LEAVE command on client and server.
8670 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8671 again. This change was made to the protocol as well. Server
8672 should not violate the protocol specification anymore.
8674 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8676 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8677 was tested. SOCKS4 was not but should work anyway.
