536 channel list now doesn't include the user mode anymore but the
537 actual channel mode. Updated protocol specs and the code in
538 client and server. Affected files are silcd/command_reply.c,
539 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
540 and lib/silcclient/command_reply.c.
542 * Save the channels list in WHOIS command reply in normal server
543 so that WHOIS always shows joined channels also in normal
544 server and not just on router. Affected file is
545 silcd/command_reply.c.
547 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

635 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
636 specs and code. Protocol TODO #19. Affected files are
637 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
638 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
640 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Added STATS command to the protocol after all, to return
643 various statistical information about the network. It can
644 be used by clients to retrieve statistical information, and
645 servers may use it to to fetch cell and network wide
646 statistics from router. Updated the protocol specs and
647 implemented it to the server. Protocol TODO #16.
648 Affected files are lib/silccore/silccommand, silcd/command.[ch],
649 silcd/command_reply.[ch].
651 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
653 * The LIST command reply in client libary now adds new channel
654 entry if the returned channel doesn't exist yet in cache,
655 and returns the channel entry to the application in the
656 command_reply client operation. Affected file is
657 lib/silcclient/command_reply.c.
659 * Changed the channel message payload's MAC generation to
660 include the IV in the MAC as well. This way all relevant
661 parts of the channel message payload are authenticated also
662 with the channel message MAC (and not only by packet MAC).
663 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
664 Affected file is lib/silccore/silcchannel.c.
666 * Fixed the SKE to save the remote version, since the
667 silc_ske_parse_version mistakenly checked wrong version,
668 after it replaced the start payload. Affected files are
669 lib/silcske/silcske.[ch].
671 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
673 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
674 string utility functions. Added there also new functions
675 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
676 Affected files lib/silcutil/silcstrutil.[ch].
678 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
679 files are lib/silcutil/silcstrutil.[ch].
681 * Defined that the security property fields in SKE SHOULD be
682 UTF-8 encoded, defined that version string MUST be US-ASCII
683 encoded, defined that passphrases sent in connection
684 authentication protocol MUST be UTF-8 encoded. Implemented
685 these to the client and server. Defined also that other
686 passphrases sent in the protocol MUST be UTF-8 encoded.
687 Affected files are lib/silcske/silcske.c,
688 lib/silcclient/protocol.c, silcd/protocol.c,
689 silcd/serverconfig.c, and lib/silccore/silcauth.c.
691 * Changed the silc_client_close_connection interface to not
692 need the SilcSocketConnection which should not be visible
693 to application. Affected files are lib/silcclient/client.c
694 and lib/silcclient/silcclient.h.
696 * Rewrote the text for Private Message Key Payload in the
697 protocol specification. Protocol TODO #11.
699 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Upgraded the protocol version to 1.1, updated protocol specs
704 * Added the nickname as new argument to NICK_CHANGE notify and
705 added it to protocol specs and implemented it to client and
706 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
707 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
708 lib/silcclient/client_notify.c.
710 * Added the killer's client ID to the KILLED notify and added
711 it to protocol specs and implemented it to client and server.
712 Protocol TODO #13. Affected files are silcd/command.c,
713 silcd/packet_receive.c, packet_send.[ch],
714 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
715 The killer's client entry is now returned to application in
716 the `notify' client operation.
718 * Fixed the Max Argument fields that had too large value set
719 in the protocol specs. Protocol TODO #14.
721 * Added the LEAVE command reply to return the ID of parted
722 channel. Updated protocol specs and implemented it to the
723 client and server. Protocol TODO #15. Affected files are
724 silcd/command.c, lib/silcclient/command_reply.c. The channel
725 entry is now returned to application in the `command_reply'
728 * Rewrote the version SKE version checking in client libary
729 and in server to use the silc_parse_version_string. Affected
730 files are lib/silcclient/protocol.c, silcd/protocol.c.
732 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
733 commands that was missing it, and updated protocol specs and
734 the server implementation. Protocol TODO #10. The affected
735 file is silcd/command.c.
737 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
738 generic reply to a generic request (REQUEST flag), and
739 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
740 way. A draft-riikonen-silc-flags-payloads-00.txt is written
741 to define the payload for DATA flag. Added the flags to
742 the implementation. Protocol TODO #9. Affected file is
743 lib/silccore/silcchannel.h.
745 Changed the client library to return the message length
746 to application as well in the channel_message and private_message
747 client operations. Affected files are
748 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
749 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
750 and lib/silcclient/client_ops_example.c.
752 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
753 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
754 the channel. Updated protocol specs and impelemented this
755 to client and server. Protocol TODO #6. Affected files are
756 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
757 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
759 Added new options m and M to CMODE command in Irssi SILC
760 client to set these modes.
762 * Deprecated all administrative commands from SILC protocol
763 since they are highly implementation specific commands.
764 Updated protocol specs. Moved the old commands in
765 implementations to private range of command types. Affected
766 files are silcd/command.c, lib/silcclient/command.c and
767 lib/silcclient/command_reply.c. Protocol TODO #8.
769 * Fixed a bug in server where sending unknown command crashes
770 the server. Affected file silcd/command.c.
772 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Added SILC_PROTOCOLVERSION macro to check protocol version
775 of a socket connection. The affected file is
776 lib/silcutil/silcsockconn.h.
778 * Added better error logging in rekey protocol. Affected file
781 * Do not check public key types in SKE during rekey. Affected
782 file lib/silcske/payload.c.
784 * Fixed the rekey protocol with PFS, which was totally broken.
785 Affected file silcd/protocol.c.
787 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
789 * Some client implementations quit network by doing first LEAVE
790 and then immediately SIGNOFF (like Bombyx). We now do check
791 after a short time after LEAVE notify and check whether the
792 client is still valid after LEAVE, and if not we remove it from
793 cache. Affected file is lib/silcclient/client_notify.c.
795 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
797 * Merged version 1.1.4 of zlib. Even if it not currently in use,
798 it's good not to have security holes here.
800 * Fixed a negative refcount situtuation for the config context.
801 Affected file is silcd/serverconfig.c.
803 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
805 * ROBOdoc documented lib/silcutil/silcutil.h.
807 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
809 * Optimized even more the SilcPacketContext structure. Now
810 totally saved 16 bytes of memory per context after optimization.
811 Affected files are lib/silccore/silcpacket.[ch].
813 * Made strict checks for valid SILC IDs. Affected file is
814 lib/silccore/silcid.c.
816 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
818 * Changed the object argument for silc_cipher_register,
819 silc_hash_register, silc_hmac_register and silc_pkcs_register
820 to const. Affected files are lib/silccrypt/silccipher.[ch],
821 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
823 * Changed the silc_get_username and silc_get_real_name to
824 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
826 * Fixed the Irssi SILC Client to use the silc_get_username and
827 silc_get_real_name insted of glib routines since the glib
828 routines only corrupt stack. Fixes the Irssi SILC to work in
829 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
831 * Fixed the Irssi to not use g_get_home_dir since it crashes
832 or returns garbage on cygwin and corrupts stack. Added function
833 get_home_dir to Irssi routines. Affected files are
834 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
836 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Made some structure optimizations. SFTP memory FS MemFSEntry
839 entry structure. Optimized SilcTask structure. Optimized
840 SilcPacketContext structure.
842 Affected files lib/silcsftp/sftp_fs_memory.c,
843 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
845 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * And yet again reverted back the config thing since Johnny
848 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
851 * Fixed memory leaks from config object. Affected files are
852 silcd/serverconfig.[ch].
854 * Added support for adding new connections to the server in rehash.
855 After rehash they take effect.
857 Added support for changing the maximum allowed connections in
858 rehash. The number can grow but going smaller is not supported.
860 Added function silc_server_num_sockets_by_remote to the
861 silcd/server_util.[ch].
863 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
865 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
867 * Added preliminary checking during config parsing for a valid
868 public/private key and removed further checks in the code.
869 Affected files are silcd/serverconfig.[ch], server.c.
871 * Moved functions silc_server_drop() and silc_server_daemonise()
872 from server.c to silcd.c since they are stricly related to
873 the application activity.
875 * Reverted a small part of the automatic ref/unref since
876 it caused a double unref in some situations. Affected
877 files are silcd/silcd.[ch], server.c, serverconfig.c.
879 * Added some .cvsignore files in the lib directory.
881 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
883 * Fixed silc_net_gethostbyaddr to correctly resolve by
884 address. Affected file lib/silcutil/silcnet.c.
886 * Fixed the notify relaying to client. The HMAC to be used
887 with relayed packets ws wrong and caused decryption failure
888 at the client end. Affected file is silcd/packet_receive.c.
890 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Created new branch silc_protocol_1_0_branch.
894 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
896 * Changed the silc_server_config_* routines to be SilcServer
897 independent. They are now officially application specific code
898 and not part of generic server implementation. Affected files
899 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
901 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
903 * Added automatic referencing of config context in the
904 silc_server_config_alloc, and automatic unreferencing in the
905 silc_server_config_destroy. Affected files are
906 silcd/serverconfig.[ch], silcd/silcd.c.
908 * Fixed the silc_log_quick handling in the logging routines.
909 It didn't log quickly when it was TRUE. Affected file is
910 lib/silcutil/silclog.c. Also the flush delay was set even
911 if it was 0 in config file. Affected file is
912 silcd/serverconfig.c.
914 * Added support for changing key pair of the server in rehash.
915 Affected file silcd/server.c.
917 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
919 * Fixed the TOPIC_SET notify to not cras. It changed the topic
920 too early, before getting the channel entry. Affected file
921 is silcd/packet_receive.c.
923 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
925 * Added functions silc_server_config_[ref/unref], these are used
926 to prevent that the config object is destroyed.
928 No longer directly affect global variables silc_log_quick and
929 silc_log_delay, they are first cached inside the config object
930 and then applied with silc_server_config_setlogfiles().
932 silc_server_config_set_defaults() is now internal to
933 serverconfig.c, there are no reasons to show this internal stuff
936 Affected files are silcd/serverconfig.[ch].
938 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
939 fprintf's to stderr, since some code may be executed again after
940 the server went into the background. Affected files are
943 * Added rehash support. Added function silc_server_rehash() that
944 will perform all the basic tasks of the rehashing procedure.
946 * Added command line option `-x, --hexdump'. This will enable the
947 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
948 The option `--hexdump' implies `--debug'.
950 * Fixed a bad bug in the logging APIs (silcutil library) where
951 the application would crash after calling silc_log_reset_all().
953 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Fixed the KICKED notify handling in client library to
956 correctly remove the channel and all entries from the
957 channel when I was kicked. This bug crashed the client.
959 Fixed yet another but in KICKED notify handling to remove
960 the kicked client correctly from the channel.
962 Affected file is lib/silcclient/client_notify.c.
964 * Fixed a minor bug in looking up correct client entry
965 in KICKED notify in server. Affected file is
966 silcd/packet_receive.c.
968 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
969 sources correctly to distribution. Fixes --with-gmp option.
971 * Removed the manual rehashing from ID Cache, and changed it
972 to use the SILC Hash Table's auto rehash feature. Affected
973 file is lib/silccore/silcidcache.c.
975 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Fixed a bug in the silc_client_nickname_format function that
978 handles the multiple same nickname formatting. Two clients
979 with same nickname caused problems after the first one left
980 and rejoined. It didn't format the nickname correctly.
981 Affected file is lib/silcclient/idlist.c.
983 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
985 * Don't change the topic if olod topic is same as new one.
986 Affected file is silcd/packet_receive.c.
988 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Added cross-reference support to the SILC Documentation
991 generator. All types across all HTML files are now cross-
992 referenced. Affected files util/robodoc/generator.c and
993 scripts/silcdoc/silcdoc.
995 * Added file lib/silcutil/silctypes.h to include all the
996 arithmetic type definitions and some macros. Removed
997 includes/bitmove.h and moved macros to silctypes.h.
999 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1003 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Added `type' argument to silc_id_payload_parse_id function which
1006 now returns the type of the ID to the sent pointer. Affected
1007 file is lib/silccore/silcid.[ch].
1009 * Added check for CMODE_CHANGE notify type that mode change is
1010 allowed by the sender. Affected file silcd/packet_receive.c.
1012 * Added check for CUMODE_CHANGE notify type that mode change is
1013 allowed by the sender. Affected file silcd/packet_receive.c.
1014 Added the ID type as CUMODE_CHANGE notify type as argument
1015 to the `notify' client operation. Affected files are
1016 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1018 * Added function silc_client_add_server to the client library.
1019 Added support for resolving also channel and server info when
1020 received unknown entity in notify packet. Affected files are
1021 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1023 * Added function silc_command_get_status to return the command
1024 status from the command reply's argument payload. Affected files
1025 are lib/silccore/silccommand.[ch].
1027 * Added check for KICKED notify type that the kicking is
1028 allowed by the client. Affected file silcd/packet_receive.c.
1030 * Created function silc_get_input which can be used to get input
1031 (echo on or off) from user on command line. Affected files are
1032 lib/silcutil/silcutil.[ch].
1034 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1036 * Optimized silc_server_packet_relay_to_channel function.
1037 Added new function silc_channel_message_payload_encrypt which
1038 can be called directly if channel message payload needs to
1039 be encrypted and is already encoded (no need to call _encode
1040 function). Packet relaying is now done by router without any
1041 extra memory allocations. Affected files are
1042 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1043 silcd/packet_send.c.

1046 as invite list and invite delete. Affected file is
1047 silcd/packet_receive.c.
1049 * Added check for TOPIC_SET notify type that the topic change is
1050 allowed by the client. Affected file silcd/packet_receive.c.
1052 * Added check for INVITE notify type that inviting is allowed by
1053 the client. Affected file silcd/packet_receive.c.
1055 * Changed the silc_server_client_on_channel to return the
1056 SilcChannelClientEntry as well. Moved the function
1057 silc_server_check_cmode_rights to server_util.[ch].
1058 Affected files are silcd/server_util.[ch], silcd/command.c.
1060 * Added function silc_server_check_umode_rights to check whether
1061 changing client's user mode is allowed. Added check for
1062 UMODE_CHANGE notify type that the umode change is allowed
1063 by the client. Affected files are silcd/server_util.[ch],
1064 silcd/packet_receive.c and silcd/command.c.
1066 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1068 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1069 ID length. It ignored that ID can be IPv6 based as well.
1070 Affected file lib/silccore/silcpacket.h.
1072 * Fixed the silc_id_id2str and silc_id_str2id to take the
1073 IPv6 address offset's into consideration. Affecte file is
1074 lib/silccore/silcid.c.
1076 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1078 * Fixed the internal Unix scheduler functions to check for
1079 NULL context they may receive. The affected file is
1080 lib/silcutil/unix/silcunixschedule.c.
1082 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1084 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1085 can specify different directory with --home command line
1086 parameter. Affected files irssi/src/silc/core/client_ops.c,
1089 * SILC-specific commands aren't now executed if the active server
1090 isn't of SILC-type, so there won't be problems with having
1091 IRC and SILC protocol support in same client. Affected files
1092 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1095 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1097 * Improved the signal support in SILC Schedule. Added new
1098 function silc_schedule_signal_call which is used by application
1099 to mark a signal to be called. It is now safe to perform
1100 any kind of tasks in signal callbacks since it is guaranteed
1101 that the application specified signal callback is called
1102 after the signal is over. Affected files are
1103 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1105 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Added `name' field to SilcChannelPrivateKey to represent
1108 application given name for the key. Moved also the context from
1109 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1110 Added the `name' argument also to the function
1111 silc_client_add_channel_private_key.
1113 Added function silc_client_current_channel_private_key to set the
1114 current channel private key in use.
1116 Added "change" command to KEY command which can be used to change
1117 the current channel private key. Bound the command also to
1118 alt+K (Alt+Shift+k).
1120 Also affected files lib/silcclient/client_channel.c,
1121 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1123 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1125 * Added silc_rng_get_byte_fast function in to the
1126 lib/silccrypt/silcrng.[ch].
1128 * Changed the interface of silc_packet_assemble and the
1129 silc_packet_send_prepare. If silc_packet_assmble is now
1130 called the application does not call silc_packet_send_prepare
1131 because the library will call it automatically. These
1132 interfaces now also return a reference to the outgoing buffer
1133 which includes the assembled packet, which the application can
1134 use to encrypt the packet.
1136 Affected files are lib/silccore/silcpacket.[ch],
1137 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1138 silcd/packet_send.c, server_backup.c and packet_receive.c.
1140 * Fixed a packet sending bug on very high load, where outgoing
1141 packet queue wasn't handled correctly and packets got corrupted.
1142 Affected files are lib/silcutil/*/silc*sockconn.c,
1143 lib/silcclient/client.c and silcd/server.c.
1145 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1147 * Added macro SILC_PACKET_DATALEN which can be used during
1148 packet assembling to check whether the data to be added to
1149 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1150 len is truncated until it fits it.
1152 Added checks for maximum length of channel message payload and
1153 private message payload also.
1155 Added checks for maximum packet length in server and in
1158 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1159 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1160 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1161 lib/silcclient/client_prvmsg.c.
1163 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1165 * Added silc_server_packet_queue_purge call to the
1166 silc_server_disconnect_remote to assure that all data in the
1167 queue before disconnecting is sent to the network. Affected
1168 file silcd/server.c.
1170 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Added the deleting of server's own ID cache entry to the
1173 silc_server_free function. Free also everything else that
1174 has been allocated in silc_server_init. The affected file
1177 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Added functions silc_parse_version_string, silc_version_to_num,
1180 and silc_ske_parse_version to parse SILC protocol style version
1181 strings. Affected files lib/silcutil/silcutil.[ch] and
1182 lib/silcske/silcske.[ch].
1184 * Added new configuration params: version_protocol, version_software
1185 and version_software_vendor to specify what version the remote
1186 host must at least be to be able to connect to server. The vendor
1187 string can be regex matched too. Added new function
1188 silc_server_connection_allowed to check maximum number of allowed
1189 connections, and allowed versions for incoming connections.
1190 Affected files are silcd/server.c, server_util.[ch] and
1193 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1195 * Added preliminary support for signals in scheduler. The
1196 signals we care about are now blocked always when the scheduler
1197 is locked. This way we can synchronise the use of signal with
1198 scheduler. It is guaranteed that when signal occurs the scheduler
1199 is not locked, and thus new tasks can be safely added to the
1202 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1203 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1204 Added new platform specific routines
1205 silc_schedule_internal_signals_[un]block and
1206 silc_schedule_internal_signal_[un]register.
1208 Added new functions to SILC Schedule API:
1209 silc_schedule_signal_[un]register. Each signal that application
1210 is going to use should be registered to the scheduler.
1212 Affected files are lib/silcutil/silcschedule.[ch],
1213 lib/silcutil/*/silc*schedule.c.
1215 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Check for unauthenticated client and server in the
1218 silc_server_new_client and silc_server_new_server functions.
1219 Affected file silcd/packet_receive.c.
1221 * Added function silc_string_is_ascii to check whether given
1222 string is 7-bit ASCII string. Affected files are
1223 lib/silcutil/silcutil.[ch].
1225 * Added function silc_id_is_valid_server_id into the
1226 silcd/serverid.c and added checking for valid Server ID's in
1227 silc_server_new_server. The Server ID must always be based
1228 on the server's public IP address.
1230 * Added logging of DISCONNECT packet message in the server.
1231 Affected file silcd/server.c.
1233 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1235 * Changed all library interfaces that use Global RNG to also
1236 accept SilcRng as argument. Affected files are
1237 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1238 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1239 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1240 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1241 lib/silccrypt/rsa.c.
1243 * Added function silc_pkcs_generate_key to the
1244 lib/silccrypt/silcpkcs.[ch] for applications so that they
1245 don't need to do pkcs->pkcs->init calls anymore.
1247 * Remove SilcSocketConnection from the SFTP API since it really
1248 wasn't needed there. The application has the information
1249 saved in its contexts anyway and the SFTP layer doesn't need
1250 know about it. Affected files lib/silcsft/silcsftp.h and
1251 lib/silcsftp/sftp_[server/client].c.
1253 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1254 The SilcSimContext is not SilcSim.
1256 * Fixed possible buffer overflows in silc_id_render in the
1257 lib/silcutil/silcutil.c.
1259 * On EPOC the global crypto module lists are not used at all
1260 in the crypto library. Added support for using the constant
1261 algorithm list on EPOC. Affected files are
1262 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1265 * Fixed the handling of third parameter of KICKED notify, since
1266 it was mistakenly updated to SILC Protocol 1.0 even though it
1267 is to be included in 1.1. Since it is not in 1.0 it is not
1268 mandatory, and this fix now handles it only if it is provided,
1269 and it is not error if it is not provided. Affected file
1270 lib/silcclient/client_notify.c.
1272 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1275 client. Affected file irssi/src/silc/core/client_ops.c.
1277 * Merged with Irssi 0.8.4 from irssi.org CVS.
1279 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1281 * Check for valid socket connection in client entries before
1282 sending any messages. Fixes a crash, but doesn't fix some
1283 other underlaying bug that is lurking there. Affected
1284 file silcd/packet_send.c.
1286 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1288 * $usermode, $cumode and $cumode_space expandos shouldn't do
1289 anything with non-SILC server records. Affected file
1290 irssi/src/silc/core/silc-expandos.c
1292 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1294 * Fixed the silc_net_check_[host/local]_by_sock to support
1295 IPv6 bound sockets as well. Now they can return IPv6 addresses
1296 as well. Affected file lib/silcutil/silcnet.c.
1298 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1299 Affected lib/silcutil/unix/silcunixnet.c.
1301 * Fixed ID rendering (at least on some platforms, not NetBSD)
1302 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1304 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Added silc_hash_public_key and silc_hash_public_key_compare
1307 functions to be used with SilcHashTable. They can be used to
1308 hash public keys and compare public keys in hash table. Affected
1309 file lib/silcutil/silcutil.[ch].
1311 * Added support for specifying multiple public keys for Client
1312 connection section in server configuration file. This makes it
1313 possible to accept multiple public keys from same host, or to
1314 make a section that accepts any incoming host, and have the
1315 accepted public keys listed in the section.
1317 Added functions silc_sever_[find/get]_public_key, added the
1318 support for this actually to all connection sections but only
1319 the Client section is currently allowed to specify multiple
1322 Affected files are silcd/server.c, server_internal.h,
1323 command.c, protocol.c, server_util.[ch], packet_receive.c.
1325 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1327 * Merged Irssi 0.8.2 from irssi.org CVS.
1329 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1331 * If silc_debug is TRUE, also output standard logging messages
1332 to stderr with the debug output.
1334 Made silc_log_reset_all() flushing all channels before returning.
1335 Also fixed some documentation typos.
1337 Affected files are lib/silcutil/silclog.[ch].
1339 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1341 * Fixed the server to check correctly the amount of connections
1342 from single host, by checking also the type of the connection.
1343 Fixed also the comparison of number of connections and number
1344 of allowed connections. Affected files are silcd/server.c,
1347 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1349 * Fixed the USERS command reply to save the user's mode on the
1350 channel as well. Fixed JOIN command reply to check whether a
1351 client is on channel already and not join it twice. Affected
1352 file lib/silcclient/command_reply.c.
1354 * Added new file silc-expandos.c into irssi/silc/core/ to return
1355 various stuff for various signal for the statusbar etc. updating.
1356 Now Irssi SILC client prints channel user modes etc. on the
1359 * The user mode (like server/router operator changes) is now shown
1360 on the Irssi SILC client's statusbar. The affected files are
1361 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1363 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1365 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1366 to SILC_SCHEDULE_[UN]LOCK macros.
1368 * Added more error printing to logs in server code. Affected
1369 files silcd/server.c and silcd/protocol.c.
1371 * Fixed -S option parsing in Irssi SILC Client. Affected file
1372 irssi/src/silc/core/silc-core.c.
1374 * Added silc_buffer_alloc_size function. Affected file is
1375 lib/silcutil/silcbuffer.h.
1377 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1380 constants. Affected files in
1381 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1384 * Changed the internal SFTP Memory FS table to const. Affected
1385 file lib/silcsftp/sftp_fs_memory.c.
1387 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Fixed the buffer formatting and unformatting routines to
1390 check the size of 64 bits types with sizeof(). Affected
1391 file is lib/silcutil/silcbuffmt.c.
1393 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Removed 0.6.x backwards support.
1397 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1399 * Changed all integer type names:
1400 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1401 to avoid collisions with other libraries using same type names
1404 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1406 * Added `prefer_ipv6' argument to the functions
1407 silc_net_gethostbyname[_async]. If it is TRUE it will return
1408 IPv6 address over IPv4. If FALSE IPv4 address is returned
1409 even if IPv6 address was found. Affected files
1410 lib/silcutil/silcnet.[ch].
1412 * Added support silc_net_create_connection[_async] to fallback
1413 to IPv4 address if IPv6 address could not be used (like if
1414 it doesn't work on a specific system). Affected file in
1415 lib/silcutil/unix/silcunixnet.c.
1417 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Added silc_schedule_reinit function to do the enlarging
1420 of the max tasks handling capabilities of the scheduler.
1421 Affected files lib/silcutil/silcschedule.[ch].
1423 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1425 * Added automatic extern "C" { ... } for C++ compilers so the
1426 application does not need to define them. Affected file
1427 includes/silcincludes.h.
1429 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1430 old name went against naming convention. Applications now
1431 include "silcclient.h" instead of "clientlibincludes.h".
1432 Removed includes/clientlibincludes.h, it is redundant now.
1434 * Renamed includes/version.h to silcversion.h.
1436 * Added really preliminary support for OS/2 into the util
1437 library. Only thread & mutex API is implemented, others
1438 are still to be implemented. Created the lib/silcutil/os2/
1439 directory. Created also file includes/silcos2.h.
1441 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1443 * Added preliminary BeOS support into the util library.
1444 Created lib/silcutil/beos/, and implemented all the needed
1445 functions to support SILC on BeOS. Created also file
1446 includes/silcbeos.h.
1448 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1450 * Added proper initializations to silc's irssi code, so it's
1451 now possible to load it as module. Affected files
1452 irssi/src/silc/core/silc-core.c,
1453 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1455 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1457 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1460 * Fixed the silcdoc document generator to correct generate
1461 docs from all kinds of filenames. Affected files are
1462 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1464 * ROBOdoc documented lib/silcutil/silcmemory.h.
1465 Added also new function silc_memdup.
1467 * Removed lib/silcutil/silcbufutil.h and moved those routines
1468 to the lib/silcutil/silcbuffer.h.
1470 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1472 * Added `user_count' to the SilcChannelEntry which now tells the
1473 number of users on the channel. The user count is now saved
1474 in normal server of global channels as well. Affected files
1475 silcd/server.c, idlist.h, packet_receive.c and command.c.
1477 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1478 include file utility functions.
1480 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1481 instead of calling directly OS routines.
1483 * Fixed NICK change printing in Irssi SILC Client. Fixed
1484 KICKED notify printing in Irssi SILC Client. Affected file
1485 irssi/src/silc/core/client_ops.c.
1487 * Fixed a NICK change bug in client library, to not recreate the
1488 client_entry->channels hash table everytime nick is changed.
1489 Affected file lib/silcclient/client.c.
1491 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1493 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1494 the SKE interface a bit.
1496 * Fixed padding problem in PKCS#1. The padding was not actually
1497 random since the random number generator was used incorrectly.
1498 This security bug affects only when encrypting with PKCS#1, and
1499 it is not currently used at all in SILC. SILC only use signing
1500 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1502 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Rewrote the notify handling in Irssi SILC client to not call
1505 the events as signals. Fixes problems with Perl support.
1506 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1508 * Send the auto-nicking NICK command in client library with
1509 little timeout after connecting. The affected file is
1510 lib/silcclient/client.c.
1512 * Added following new config file settings:
1513 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1514 key_exchange_timeout, conn_auth_timeout, connections_max,
1517 Implemented all the new config settings handling in the server.
1519 Optimized the use of SKE Mutual flag usage. Use it only
1520 if connection authentication protocol is not based in public
1523 Renamed all SilcServerConfigSection* to SilcServerConfig*
1524 to have a bit shorter names.
1526 Affected files silcd/serverconfig.[ch], server.[ch], and
1529 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1531 * Cleaned up the listening sockets code, preparing for the rehash
1532 support. Affected file is silcd/server.c.
1534 * Fixed some output messages. Affected files are silcd/silcd.c,
1537 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1539 * Create lib/doc/silcrng_intro.html document as introduction
1540 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1542 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1544 * Fixes to the silcd config template. Affected file is

1548 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1550 * Removed param_name member from client, server, and router
1551 section structs, now identifying the param directly.
1553 Added CONFIG_FREE_AUTH macro in config file parsing.
1555 Affected files are silcd/serverconfig.[ch].
1557 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1559 * Fixed command line parameter handling. All SILC initialization
1560 is now done in silc_core_init() which also fixes autoconnecting
1563 Affected files irssi/src/silc/core/silc-core.c,
1564 irssi/src/fe-text/silc.c.
1566 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1568 * Added new configuration options and blocks:
1569 keepalive_secs, reconnect_count, reconnect_interval,
1570 reconnect_interval_max, reconnect_keep_trying and
1571 require_reverser_lookup. Added ConnectionParam block, and
1572 implemented the connection parameters when connecting as
1573 initiator and when accepting connections as responder.
1575 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1576 whether given configuration value has been given already.
1578 Affected files silcd/serverconfig.[c], server.[c].
1580 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1581 algorithm parts and created new file silcalgs.conf, that
1582 is now included from the example_silcd.conf.in.
1584 * Optimized the silc_server_connect_to_router_second to take
1585 the connection configuration object from the SilcServerConnection
1586 object instead of finding it during the connecting phase.
1587 Added the configuration object to SilcServerConnection struct.
1588 Affected files silcd/server_internal.h, server.c.
1590 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Add the client on channel after it was resolved at the
1593 channel message receiving, and it was not already on the
1594 channel. Affected file lib/silcclient/client_channel.c.
1596 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1605 Affected file silcd/serverconfig.[ch].
1607 * Removed doc/example_silc.conf.in since it is redundant.
1608 The make install will now install irssi/silc.conf file.
1610 * Added new Passphrase and Publickey authentication methods to
1611 config file, allowing both public key and passphrase based
1612 authentication to be set at the same time.
1614 Added `prefer_passphrase_auth' setting in config file which
1615 can be used to set to prefer passwd auth if both passwd and
1616 public key is set. If not set, public key is preferred.
1617 This has effect only when being initiator (responder will try
1620 Added support for authentication with passphrase and public key
1621 at the same time. The passphrase is tried first always since
1622 it is faster to check.
1624 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1626 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1628 * Merged the new SILC Config library, with the server parsing
1629 support. Read the header file silcconfig.h or the toolkit
1630 documentation for the news. Affected files are

1652 * Allow zero length channel messages inside the Channel Message
1653 Payload. Affected file lib/silccore/silcchannel.c.
1655 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1656 as header filenames.
1658 * Removed lib/silcclient/README and created HTML file
1659 lib/silcclient/silcclient_using.html, which is now included
1660 as part of Toolkit documentation.
1662 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Fixed CUMODE_CHANGE notify handling to change the mode of
1665 correct client. Affected file lib/silcclient/client_notify.c.
1667 * Make silc_rng_alloc fail if it cannot allocate the sha1
1668 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1672 * Fixed the file transfer's key agreement payload to include
1673 zero port also if the hostname is NULL because it could not
1676 Call file transfer monitor callback now also if error occurs
1677 during key agreement protocol.
1679 Changed the silc_client_file_send interface to return the
1680 SilcClientFileError instead of session id. The session ID
1681 is returned into pointer provided as argument.
1683 Check that the file exists locally before sending the
1684 file transfer request at all.
1686 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1688 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1689 error than can occur while key agreement protocol. Affected
1690 file lib/silcclient/silcapi.h.

1696 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1697 SILC_LOG_WARNING to give out Warning and not Error. Affected
1698 file lib/silcutil/silclog.c.
1700 * Fixed the channel message payload decryption in the function
1701 silc_channel_message_payload_decrypt to not modify the original
1702 buffer before it is verified that the message decrypted
1703 correctly. Otherwise, next time it is called with correct
1704 channel key it won't encrypt since the payload is corrupted.
1705 Affected file lib/silccore/silcchannel.c.
1707 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1717 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1719 * Fixed a bug in hash table internal routine for traversing
1720 the table with foreach callback. The current entry may
1721 become invalid in the callback but it was referenced after
1722 the callback returned.
1724 Do not allow auto rehashing of hash table during the
1725 silc_hash_table_foreach operation, for same reasons as it is
1726 not allowed for SilcHashTableList. Affected files are
1727 lib/silcutil/silchashtable.[ch].
1729 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1731 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1732 Win32 DLL. extern's in header files are now declared with
1735 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed private message handling. It used some old code that
1738 caused the client to crash. Affecte file is
1739 lib/silcclient/client_prvmsg.c.
1741 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1743 * Added function silc_client_add_channel,
1744 silc_client_replace_channel_id, and removed functions
1745 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1746 from client library.
1748 * Added cross reference of the joined channels to the
1749 SilcClientEntry, and changed the SilcChannelEntry's
1750 users list to SilcHashTable. The affected files are
1751 lib/silcclient/idlist.[ch].
1753 * Fixed a bug in hash table tarversing. While the hash table
1754 is traversed with SilcHashTableList the table must not be
1755 rehashed. It is now guaranteed that auto rehashable tables
1756 are not rehashed while tarversing the list. Also defined that
1757 silc_hash_table_rehash must not be called while tarversing
1758 the table. Added function silc_hash_table_list_reset that must
1759 be called after the tarversing is over. The affected files are
1760 lib/silcutil/silchashtable.[ch].
1762 * Changed all hash table traversing to call the new
1763 silc_hash_table_list_reset in server and in client library.
1765 * Added function silc_client_on_channel to return the
1766 SilcChannelUser entry if the specified client entry is joined
1767 on the specified channel. This is exported to application as
1768 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1770 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * Fixed founder regaining problem with JOIN command on normal
1773 server. The notify for mode change must be sent always and
1774 not only if !cmd->pending. Affected file silcd/command.c.
1776 * Fixed the WHOWAS command's reply sending to support the
1777 lists correctly. Affected file silcd/command.c.
1779 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1781 * When sending JOIN command to router for processing the
1782 sender's old command identifier was not saved back to the
1783 sender's command context, fixed now. The affected file is
1786 * Create the key in JOIN command of the router did not return
1787 the channel key, added check for this. Affected file is
1790 * Fixed a channel ID update bug in JOIN command reply. Do
1791 not directly upgrade the ID but call the function
1792 silc_idlist_replace_channel_id if the ID was changed.
1793 Affected file silcd/command_reply.c.
1795 * Fixed memory leaks from command calling if it would fail.
1796 Affected file silcd/command.c.
1798 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1800 * Applied patches from cras:
1802 Memory leak fixes around libaries, irssi window resize fix,
1803 new silclist.h and silcdlist.h, all extern inline changed to
1806 * Removed dotconf from lib/dotconf, not needed anymore.
1808 * Removed TRQ from lib/trq, not needed anymore.
1810 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1811 with server connections. Later this will be configurable
1812 in config file after new config file is done. Affected file
1815 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1817 * Fixed a crash in server related to channel announcements.
1818 Affected file silcd/server.c.
1820 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1822 * Fixed memory leaks in silc_server_create_new_channel*
1823 functions. Affected file silcd/server.c.
1825 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1826 which ID was changed. This way the router will send the
1827 user list for the channel again, and server won't be in
1828 desync in some rare circumstances. Affected file is
1829 silcd/packet_receive.c.
1831 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1833 * Check for NULL socket pointer in the function
1834 silc_server_packet_send_to_channel_real. Affected file
1835 silcd/packet_send.c.

1842 * Fixed some header addition to Toolkit distribution in
1843 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1845 * Added lib/silcclient/client_ops_example.h as an template
1846 file for application programmers to quickly start using
1847 the SilcClientOperation functions in their application.
1848 Updated the lib/silcclient/README as well to tell about this
1849 nice file made available.
1851 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1853 * Call silc_server_remove_from_channels when removing client
1854 entry when NO_SUCH_CLIENT_ID was received. Affected file
1855 is silcd/command_reply.c.
1857 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1859 * Added server & router operator statistics updating. Affected
1860 file silcd/packet_receive.c and silcd/command.c.
1862 * Fixed the SERVER_SIGNOFF notify handling on normal server
1863 not to save the history information for clients. Same was
1864 fixed earlier in remove_clients_by_server function, but not
1865 here. Affected file silcd/packet_receive.c.
1867 * Raised the default connection-retry count from 4 to 7 in
1868 server. Affected file silcd/server.h.
1870 * Cancel any possible reconnect timeouts when we start the
1871 key exchange. Affected file silcd/server.c.
1873 * Do not reconnect on connection failure when SCONNECT was
1874 given. Affected files silcd/server.[ch].
1876 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1878 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1880 * Fixed the NICK command to always give the unformatted
1881 nickname to the one giving the NICK command. If unformatted
1882 nickname is cached already it will be formatted and the
1883 local entry will always get the unformatted nickname.
1884 Affected file lib/silcclient/idlist.c.
1886 * Fixed some double frees from client library commands.
1887 Affected file is lib/silcclient/command.c.
1889 * Fixed CUMODE command in server to assure that no one can
1890 change founder's mode than the founder itself, there was a
1891 little bug. Affected file silcd/command.c.
1893 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Removed the SilcClientCommandDestructor from the client
1896 libary, it is not needed anymore. Affected files are
1897 lib/silcclient/silcapi.h, command[_reply].[ch],
1898 client_notify, idlist.c.
1900 * Fixed GETKEY command to first resolve client, and then
1901 resolve the server only if the client was not found, instead
1902 of resolving both at the same time. Affected file is
1903 lib/silcclient/command.c.
1905 * Added silc_client_start_key_exchange_cb and lookup the
1906 remote hostname and IP address before starting the key
1907 exchange with server. The affected file is
1908 lib/silcclient/client.c.
1910 * The server's public key is now saved using the IP address
1911 of the server and not the servername for the filename.
1912 The hostname public key filename is checked as an fall back
1913 method if the IP address based filename is not found.
1915 Fixed the GETKEY command to save the fetched server key
1916 in correct filename.
1918 Print the remote server's hostname now when new key is
1919 received during connection process. Affected file is
1920 irssi/src/silc/core/client_ops.c.
1922 * Return always our own public key to the client if it asks
1923 for it with GETKEY command. Affected file silcd/command.c.
1925 * Removed the use_auto_addr variable from default config
1926 file since it was in wrong section. Affected file is
1929 * Fixed TOPIC_CHANGE notification to not route it when it
1930 was sent using silc_server_send_notify_to_channel function.
1931 Affected file silcd/command.c.
1933 * Fixed silc_server_send_notify_kicked to send the kicker's
1934 Client ID also, it was missing. Affected files are
1935 silcd/command.c, silcd/packet_send.[ch].
1937 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1939 * Do not save client history information in SERVER_SIGNOFF.
1940 Fixes the bug in normal server that it does not detect
1941 the client becoming valid after the server becomes back
1942 online. Affected file silcd/server_util.c.
1944 * Added `sock_error' field into the SilcSocketConnection
1945 context. When error occurs during socket operation (read
1946 or write) the error is saved. Added also new function
1947 silc_socket_get_error to return human readable socket error
1948 message. Affected files are lib/silcutil/silcsockconn.[ch],
1949 lib/silcutil/unix/silcunixsockconn.c, and
1950 lib/silcutil/win32/silcwin32sockconn.c.
1952 * The server now prints the socket error message in the
1953 signoff for client. Affected file silcd/server.c.
1955 * Fixed the `created' channel information sending from router
1956 to server in JOIN command. Checks now whether the channel
1957 really was created or not and set it according that.
1959 Fixed the JOIN command to use the client entry's current
1960 ID during the joining procedure instead of the one it sent
1961 in the command (it is checked though), since it can change
1962 between the packet processing and command processing, and
1963 would just case unnecessary pain in the client end. Affected
1964 file silcd/command.c.
1966 * Fixed a channel key payload sending to use correct channel
1967 ID when the server was forced to change the channel's ID by
1968 router. Router sent the key payload with the old Channel ID.
1969 Affected file silcd/packet_receive.c.
1971 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1973 * Call silc_server_save_channel_key only if the key payload
1974 was provided in the JOIN command's command reply. Affected
1975 file silcd/command_reply.c.
1977 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1979 * Fixed silc_mp_sizeinbase to return the value correctly with
1980 MPI. Affected file lib/silcmath/mp_mpi.c.
1982 * Fixed the stop_server signal to correctly stop the scheduler
1983 and gracefully stop the server when SIGTERM or SIGINT signals
1984 are received. Affected file silcd/silcd.c.
1986 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1988 * Simple handling of TERM and HUP signals. Also added some log
1989 flushing call around. Affected file is
1992 * Fixed small bugs in silclog.c. Now buffering output will take
1993 effect after 10 seconds since startup: This will ensure that
1994 no important startup messages are lost. Also output redirection
1995 will preserve original format ([Date] [Type] message).
1996 Affected file is lib/silcutil/silclog.c.
1998 * Added two options to the config file, in the logging section:
1999 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2000 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2002 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Do not print the warning about log files not being initialized
2005 more than once to avoid excess logging. Affected file is
2006 lib/silcutil/silclog.c.
2008 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2009 the SIM copying in make install in Makefile.am.pre.
2011 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2013 * Rewritten silclog APIs. Globally interesting changes follows:
2014 silc_log_set_files() changed to silc_log_set_file().
2015 silc_log_set_callbacks() changed to silc_log_set_callback().
2016 ROBOdoc documented silclog header file.
2017 SilcLogCb now returns bool to wether inihibit the default
2018 handler or not (to keep the old behaviour return always TRUE).
2019 The new APIs should also fix the problem of the
2020 silcd_error.log file that was written in the current directory.
2023 Log files streams will remain opened after silc_log_set_file()
2024 call, means less CPU usage notably on high traffic servers.
2025 File streams are now full buffered, and flushed to the disk
2026 every 5 minutes, lesses HD activity and CPU usage.
2027 Messages can be redirected, allowing admins to configure
2028 one single logfile for all server messages.
2029 the silc_log_quick global variable to activate fast-logging.
2030 Affected files lib/silcutil/silclog.[ch]
2032 * Changed some code to conform new silclog APIs. Affected
2033 files are doc/example_silcd.conf.in, silcd/server.c
2034 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2037 * Fixed a memory leak that could occur in some situations.
2038 Affected file silcd/serverconfig.c.
2040 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Added the silc_client_del_client to remove the client from
2043 all channels as well. Affected file lib/silcclient/idlist.c.
2045 * Fixed the client library to correctly remove the client
2046 from all channels when the client entry is being destroyed.
2047 Affected file lib/silcclient/client_notify.c, command.c.
2049 * Added auto-nicking support to the client library. If the
2050 applicatio now sets client->nickname it will be sent to the
2051 server after connecting by the library. This way for example
2052 SILCNICK (or IRCNICK) environment variables will have effect
2053 and always change the nickname automatically to whatever
2054 it is wanted. Affected file lib/silcclient/client.[ch].
2056 * Renamed silc_server_command_bad_chars to the
2057 silc_server_name_bad_chars and moved it to the
2058 silcd/server_util.[ch]. Added also new function
2059 silc_server_name_modify_bad to return nickname that
2060 includes bad characters as new nickname without those
2061 bad characters. This check and modify is now used in
2062 silc_server_new_client when the username is initially set
2063 as nickname, so it must be checked to be valid nickname.
2064 Affected file silcd/packet_receive.c.
2066 * The nickname length is now taken from the packet for real
2067 and not trusted to strlen() since it clearly can return
2068 wrong length for nickname including bad characters. This
2069 also applies to channel names. Affected file silcd/command.c.
2071 * Removed the lib/silcsilm/modules directory. Modules are now
2072 compiled into the lib/silcsim. Fixed the copying of the
2073 modules to follow symbolic links in Makefile.am.pre.
2075 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2077 * Fixed silc_string_regexify list creation. Fixes bugs with
2078 BAN and INVITE commands in server. The affected file is
2079 lib/silcutil/unix/silcunixutil.c.
2081 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Removed the command destructor entirely from the server's
2084 command and command reply routines. It is not needed, and
2085 its usage was buggy and caused crashes. Affected files are
2086 silcd/command[_reply].[ch].
2088 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Cancel protocol and NULL sock->protocol if timeout
2091 occurred during protocol. Affected file silcd/server.c.
2093 * Cancel protocol timeouts always before calling the final
2094 callback, to assure that after final callback is called
2095 no other state will be called for the protocol anymore.
2096 Affected file silcd/protocol.c.
2098 * Print error log if incoming connection configuration could
2099 not be found. Affected file silcd/server.c.
2101 * Fixed JOIN command to correctly save the founder mode
2102 to the client on normal SILC server, when the channel
2103 was created by the router. Affected file silcd/command.c.
2105 * Fixed LIST command (hopefully) to send correct reply
2106 packets. Affected file silcd/command.c.
2108 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * The silc_packet_receive_process now returns FALSE if the
2111 read data was invalid packet, and TRUE if it was ok.
2113 The server now checks that if unauthenticated connection
2114 sends data and its processing fails the server will close
2115 the connection since it could be a malicious flooder.
2117 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2119 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * Make sure the warning about error opening a log file is
2122 printed only once and not everytime it fails (produces
2123 too much useless log). Affected file lib/silcutil/silclog.c.
2125 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2127 * Made the silc_server_daemonise() function more readable.
2128 Affected file silcd/server.c.
2130 * Pid file is now optional, the user may comment it out from
2131 the config file. Removed define SILC_SERVER_PID_FILE, we
2132 don't need a default any longer. Affected file
2133 configure.in.pre, lib/Makefile.am.pre.
2135 * Make some use of the pid file. The server now dies at startup
2136 if it detects a valid pid file on his path. The server would
2137 die anyway in this circumstance, because of the bind() failure.
2138 Affected file silcd/silcd.c.
2140 * No longer compiling lib/dotconf.
2142 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Fixed JOIN command parsing not to crash. Affected file
2145 lib/silcclient/command.c.
2147 * Fied the NICK_CHANGE notify to add the new client entry
2148 even it is resolved. This removes an <[unknown]> nick
2149 thingy bug in the client. Affected file is
2150 lib/silcclient/client_notify.c.
2152 * Do not try to allocate 0 bytes (efence does not like it)
2153 in lib/silccore/silccomand.c when encoding payload.
2155 * Do not take IRCNICK as nickname in Irssi SILC client since
2156 it is not possible to set nickname before hand connecting
2157 the server (TODO has an entry about adding auto-nicking
2160 * Changed the silc_server_command_pending to check whether
2161 there already exists an pending entry with the specified
2162 command, command identifier and pending callback. This is
2163 to fix IDENTIFY and WHOIS related crashes that may register
2164 multiple pending commands with same identifier. Affected
2165 file silcd/command.c.
2167 * Fixed the server to reconnect to the router even if it
2168 was already reconnecting and EOF was received. This to
2169 fix a possibility that the server wouldn't ever try to
2170 auto-reconnect to the router. Affected file silcd/server.c.
2172 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Fixed the server's password authentication to use the
2175 length of the locally saved password, and not the one
2176 sent in the packet. Affected file silcd/protocol.c.
2178 * Fixed same password authentication problem in the
2179 Authentication Payload handling routines in
2180 lib/silccore/silcauth.c.
2182 * Yet another password authentication problem fixed with
2183 channel password handling in silcd/command.c.
2185 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * If first character of string in silc_parse_userfqdn is '@'
2188 then do not parse it. Affected file is
2189 lib/silcutil/silcutil.c.
2191 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * Fixed minor bug in IDENTIFY command reply sending, which
2194 caused various weird problems during JOIN when it was
2195 resolving names for users. Affected file silcd/command.c.
2197 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Fixed the IDENTIFY command reply sending to chech better valid
2200 clients. It was possible to send incomplete list of replies.
2201 Affected file silcd/command.c.
2203 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2205 * Added silc_client_command[s]_[un]register functions now to
2206 dynamically register the commands in client library. Removed
2207 the static table of commands. This allows the client library
2208 to call commands without causing the application to know about
2209 what commands library has called.
2211 Removed the INFO command reply kludge to detect when the command
2212 was called by library. Now library use its own command reply
2213 function for INFO command.
2215 Added function silc_client_command_call to call a command.
2216 Application can use it to call command, not access the structure
2219 Now all commands that are sent by the client library (not
2220 explicitly sent by application) use own command reply functions.
2222 Affected files around lib/silcclient/ and in
2223 irssi/src/silc/core/.
2225 * Fixed the WHOIS command reply sending to chech better valid
2226 clients. It was possible to send incomplete list of replies.
2228 Fixed the WHOIS and IDENTIFY to send the request to router
2229 if normal server did not do it and did not find any results.
2231 Affected file silcd/command.c.
2233 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Moved the internal data from SilcClient context into its
2236 own file, not accesible to application. Affected files
2237 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2238 and other files in client library.
2240 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Added doc/examples installation target in Makefile.am.pre.
2245 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2248 commands the found client entry will be removed from the
2249 cache, after notifying application about the error. Affected
2250 file lib/silcclient/command_reply.c.
2252 * Changed the /MSG to check for exact nickname user gave, and
2253 not let `nick' match `nick@host' if it is only one found. Now,
2254 user must type the exact nickname (like nick@host2) even if
2255 there are no more than one same nicks found. This is to avoid
2256 a possibility of sending nickname to wrong nickname since
2257 `nick' could match `nick@host'. Affected file is
2258 irssi/src/core/silc-servers.c.
2260 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Do not print "you are now server operator" or similar when
2263 giving /away command. Affected files are
2264 irssi/src/silc/core/client_ops.c, silc-servers.h.
2266 * Made the silc_server_command_pending_error_check to send
2267 the same command reply payload it received back to the
2268 original sender of the command. This way all arguments
2269 that was received by the server will be received by the
2270 client too. Affected file silcd/command.c.
2272 * Added the silc_idcache_add to return the created cache entry
2273 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2275 * Add global clients to expire if they are not on any channel.
2276 This is because normal server will never know if they signoff
2277 if they are not on any channel. The cache expiry will take
2278 case of these entries. This is done by normal servers only.
2279 The affected files are silcd/command_reply.c,
2280 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2282 * If server receives invalid ID notification for WHOIS or
2283 IDENTIFY and the ID exists in the lists, it is removed.
2284 Affected file silcd/command_reply.c.
2286 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2287 in client then client entry that it matches is searched and
2288 the nickname is printed on the screen for user. Affected
2289 file irssi/src/silc/core/client_ops.c.
2291 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Use cache entry expire time in the LIST command reply to
2294 purge old entries from the cache after the LIST command
2295 reply has been received. This way we don't have non-existent
2296 entries in the cache for too long. Affected file is
2297 silcd/command_reply.c.
2299 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * If we are normal server, and we've not resolved client info
2302 in WHOIS or IDENTIFY from router, and it is global client,
2303 we'll check whether it is on some channel. If it is not
2304 then we cannot be sure about its validity and will resolve it
2305 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2306 file silcd/command.c.
2308 * Search channel by name (if possible) rather than by ID
2309 in IDENTIFY command's command reply. Affected file is
2310 silcd/command_reply.c.
2312 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2315 Updated specs and implemented it. Affected file silcd/command.c,
2316 silcd/packet_send.c and silcd/packet_receive.c.
2318 * Implemented the <founder auth> payload handling in the JOIN
2319 command. If provided all conditions for channel joining
2320 except requirement to provide correct passphrase can be
2321 overrided by the channel founder. Updated the protocol specs.
2322 Affected file silcd/command.c.
2324 Added support for founder auth in JOIN command in client
2325 library. Fixed the parsing of the JOIN command now to support
2326 all options as they should be. The affected file is
2327 lib/silcclient/command.c.
2329 * Optimized the WHOIS and IDENTIFY commands to send the request
2330 to router only if it includes nicknames or other names. If
2331 they include only IDs then check the local cache first before
2332 routing. Affected file is silcd/command.c.
2334 * Added channels topic announcements. Affected file is
2335 silcd/packet_receive.c and silcd/server.c.
2337 * Fixed the silc_server_send_notify_topic_set to really destine
2338 the packet to channel. Affected file silcd/packet_send.c.
2340 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2341 library. Affected file lib/silcclient/client_notify.c.
2343 * Added UMODE announcements. Affected file silcd/server.c.
2345 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Memory leak fixes in:
2349 lib/silcutil/silcsockconn.c
2350 lib/silcske/silcske.c
2351 lib/silcske/groups.c
2353 lib/silccrypt/silcpkcs.c
2354 lib/silccore/silccommand.c
2355 lib/silccore/silcidcache.c
2360 * ROBOdoc documented the lib/silcske/groups.h file and a
2361 bit changed the interface for better.
2363 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2365 * Update the client entry context in the ID cache after
2366 nick change. Affected file lib/silcclient/command.c.
2367 Fixes the CUMODE command when regaining founder privileges,
2368 and a little WHOIS problem.
2370 * Fixed silc_net_gethostbyname to correctly call the
2371 inet_ntop. Affected file lib/silcutil/silcnet.c.
2373 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2375 * Added IPv6 support checking to the configure.in.pre, added
2376 also --enable-ipv6 option to override the check. Affected
2377 file configure.in.pre.
2379 * The silc_thread_create now calls the start function
2380 directly if threads support is not compiled in. Removes
2381 ugly #ifdef's from generic code. Affected files are
2382 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2384 * Added silc_net_gethostby[name/addr]_async to asynchronously
2385 resolve. Affected files are lib/silcutil/silcnet.[ch].
2387 * Added support for rendering IPv6 based server, client and
2388 channel IDs. Affected file lib/silcutil/silcutil.c.
2390 * Added support for creating IPv6 based server IDs. Affected
2391 file is silcd/serverid.c.
2393 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2395 * Added silc_net_gethostby[addr/name] into the
2396 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2397 routines. Added silc_net_is_ip[4/6]. Affected file is
2398 lib/silcutil/unix/silcunixnet.c. All routines that take
2399 address as argument now supports both IPv4 and IPv6 addresses.
2401 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2403 * Fixed LIST command reply sending in server. Affected file
2406 * Server now sends the kicker's client ID in the KICK notify
2407 to the kicked client. Affected file silcd/command.c.
2409 * The client library now parses the kickers client ID and
2410 UI displays it. Affected files lib/silcclient/client_notify.c
2411 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2413 * Made all payload parsing function prototypes consistent.
2414 They all take now const unsigned char * and uint32 pair as
2415 the payload data instead of SilcBuffer. Changes all around
2416 the source tree. Other unsigned char* -> const unsigned char*
2417 changes around the tree as well.
2419 * Optimized SFTP client and server packet sending not to
2420 allocate new buffer for each packet but to recycle the
2421 first allocated buffer. Affected files are
2422 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2424 * Optimized the SFTP client to use SilcList instead of
2425 SilcDList for requests, because it is faster. Affected file
2426 is lib/silcsftp/sftp_client.c.
2428 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2429 into lib/silccore/silcid.[ch].
2431 Renamed silcpayload.[ch] into silcargument.[ch].
2433 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * If client entry is deleted with active key agreement
2436 session, abort the session.
2438 The silc_client_abort_key_agreement now calls the completion
2439 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2441 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2444 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Don't use __restrict in older GCC's. Affected file is
2447 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2449 * silc_net_localhost now attempts to reverse lookup the
2450 IP/hostname. Affected file lib/silcutil/silcnet.c.
2452 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2453 command. It can be used to gain founder privileges at
2454 the same time when joining the channel.
2456 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2457 kicker's client ID as well. Updated protocol specs.
2459 Defined that the server must send SILC_COMMAND_IDENTIFY
2460 command reply with error status to client who sent
2461 private message with invalid client ID.
2463 Updated the protocol specification.
2465 * Added silc_server_send_command_reply to send any
2466 command reply. Affected file silcd/packet_send.[ch].
2468 * Added silc_id_payload_encode_data to encode ID payload
2469 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2471 * The server now send IDENTIFY command reply with error
2472 status if client ID in private message is invalid. Affected
2473 file silcd/packet_receive.c.
2475 * Save the server key file with server's IP address in
2476 the filename instead of hostname. The affected file is
2477 irssi/src/silc/core/client_ops.c.
2479 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2484 * Added libtool support for compiling shared objects in
2485 lib/silcsim. Affected file configure.in.pre and
2486 lib/silcsim/Makefile.am. Original patch by cras.
2488 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Pid file configuration, and server's config file fixes
2491 patch by toma. Updated CREDITS file.
2493 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Fixed silc_client_channel_message to not try to decrypt
2496 the message twice if it resolved the destination client
2497 information. This could cause of dropping one channel
2498 message. Affected file lib/silcclient/client_channel.c.
2500 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2503 lib/silcclient/client.c. This function is used when the SILC
2504 Client is run under some other scheduler, or event loop or
2505 main loop. On GUI applications, for example this may be
2506 desired to used to run the client under the GUI application's
2507 main loop. Typically the GUI application would register an
2508 idle task that calls this function multiple times in a second
2509 to quickly process the SILC specific data.
2511 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2513 * Fixed silc_server_drop() for dropping the supplementary
2514 groups as well, this could cause a security hole on some
2517 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2522 * Write PID file after dropping privileges. Added -F option
2523 to run server on foreground. A patch by debolaz.
2524 Affected files silcd/server.c, silcd/silcd.c.
2526 * Fixed MOTD to return the MOTD file server name. Affected
2527 file silcd/command.c.
2529 * Added INFO command reply handling to the Irssi SILC Client.
2530 Affected file irssi/src/silc/core/client_ops.c.
2532 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Fixed the silc_idcache_list_* routines to really support
2535 the dynamic list. Fixes a crash. Affected file is
2536 lib/silccore/silcidcache.c.
2538 * Fixed the LIST command reply to really call LIST command's
2539 pending callbacks. Affected file silcd/command_reply.c.
2541 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Update conn->local_entry->nickname after giving NICK
2544 command. Affected file lib/silcclient/command.c.
2546 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2548 * Added the [pid] option to the silcd configuration file
2550 Affected files: serverconfig.[ch] and silcd.c
2552 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Save fingerprint in WHOIS command reply in server.
2555 Affected file silcd/command_reply.c.
2557 * Fixed NICK commands pending callback registration.
2558 Affected file lib/silcclient/command.c.
2560 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Use ++server->cmd_ident when sending commands in server,
2563 instead of random number. Affected file silcd/command.c.
2565 * Fixed GETKEY command reply to call actually GETKEY pending
2566 command callbacks. Affected file silcd/command_reply.c.
2568 * A bit stricter check for nicknames. Check for same nickname
2569 in NICK command also. Affected file silcd/command.c.
2571 * Do not call INFO command everytime client ID changes, only
2572 during first connecting. Affected file lib/silcclient/client.c.
2574 * Set the new nickname only after successful command reply for
2575 NICK command is returned by server. Affected file
2576 lib/silcclient/command.c.
2578 * Remove nicknames from nicklist during server_signoff notify.
2579 Should fix /NAMES bit more. The affected file is
2580 irssi/src/silc/core/silc-channels.c.
2582 * Added `fingerprint' field to the SilcIDListData in the
2583 silcd/idlist.h to hold the fingerprint of the client's
2586 Send the fingerprint of the client's public key in WHOIS
2589 Affected files silcd/command.c, and silcd/idlist.[ch].
2591 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2592 create fingerprint from given data.
2594 * Show the fingerprint of the client's public key in WHOIS.
2595 Affected files irssi/src/module-formats.[ch] and
2596 irssi/src/silc/core/client_ops.c.
2598 * Format the multiple same nicknames also during JOIN and
2599 NICK_CHANGE notifys. Affected file is
2600 lib/silcclient/client_notify.c.
2602 * Do not print error on screen for invalid private message
2603 payload since it can come if someone is sending private
2604 messages with wrong key. Affected file
2605 lib/silccore/silcprivate.c.
2607 * Fixed multiple concurrent /PING crash. Affected file
2608 lib/silcclient/command.c.
2610 * Changed the wrong ID encoding. All IP addresses must be
2611 in MSB first order in encoded format. They were encoded
2612 wrong and was in LSB format. Affected files are
2613 silcd/serverid.c, lib/silcutil/silcutil.c.
2615 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2617 * Call the `connect' client operation through the scheduler
2618 in case of error. Affected file lib/silcclient/client.c.
2620 * Call the `failure' client operation even if the error
2621 occurred locally during a protocol. Affected file is
2622 lib/silcclient/protocol.c.
2624 * Added support of sending LIST command to router from normal
2625 server. This way normal server can get list of all channels
2626 in the network too. Fixed the channel list sending in the
2627 server too. Affected files are silcd/command.c, and
2628 silcd/command_reply.[ch].
2630 * Added silc_server_update_channels_by_server and
2631 silc_server_remove_channels_by_server. They are used during
2632 disconnection of primary router and in backup router protocol.
2633 Affected file silcd/server_util.[ch], silcd/server.c and
2634 silcd/server_backup.c.
2636 * Fixed channel adding to global list in IDENTIFY command
2637 reply in server. Affected file silcd/command_reply.c.
2639 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * If the incoming packet type is REKEY or REKEY_DONE process
2642 that packet always synchronously. Fixes yet another MAC
2643 failed error on slow (dialup) connections. Affected file
2644 lib/silcclient/client.c and silcd/server.c.
2646 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * Call check_version SKE callback for initiator too. Affected
2649 file lib/silcske/silcske.c.
2651 * Implemented fix for security hole found in the SKE that was
2652 fixed in the specification few days back; the initiator's
2653 public key is now added to the HASH value computation.
2654 Added backwards support for the old way of doing it too, for
2655 old clients and old servers. Affected file is
2656 lib/silcske/silcske.c.
2658 * Enabled mutual authentication by default in SKE. If initiator
2659 is not providing mutual authentication the responder will
2660 force it. This will provide the proof of posession of the
2661 private key for responder. The affected files are
2662 lib/silcclient/protocol.c and silcd/protocol.c.
2664 * Do not cache anymore the server's public key during SKE.
2665 We do mutual authentication so the proof of posession of
2666 private key is done, and if the server is authenticated in
2667 conn auth protocol with public key we must have the public
2668 key already. Affected file silcd/protocol.c.
2670 * Added new global debug variable: silc_debug_hexdump. If
2671 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2672 file lib/silcutil/silclog.[ch].
2674 * Fixed compilation warning due to char * -> const char *.
2675 Affected files lib/silcutil/silcnet.h, and
2676 lib/silccore/silcauth.[ch].
2678 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Fixed CMODE command when new channel key was created. If
2681 the creation failed the old key was removed. Next time giving
2682 same command would crash the server since the old key was
2683 freed already. Affected file silcd/command.c.
2685 * Fixed the silc_server_announce_get_channels to not crash
2686 on reconnect. Affected file silcd/server.c.
2688 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Added silc_log_set_debug_string function to set a regex
2691 string to match for debug output. Only the function names,
2692 or filenames matching the given debug string is actually
2693 printed. This way it is possible to filter out those debug
2694 strings that user is not interested in.
2696 Fixed a bug in silc_string_regexify.
2698 Affected files lib/silcutil/silclog.[ch], and
2699 lib/silcutil/unix/silcunixutil.c.
2701 * Changed the -d options in both server and Irssi SILC client
2702 to take the debug string as argument. Affected files
2703 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2705 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Added silc_hash_babbleprint to create a Bubble Babble
2708 Encoded fingerprint. The encoding is developed by Antti
2709 Huima (draft-huima-babble-01.txt), and it creates human
2710 readable strings out of binary data. Affected file
2711 lib/silccrypt/silchash.[ch].
2713 * Print the babble print now in addition of fingerprint as well
2714 in Irssi SILC client. Affected files are
2715 irssi/src/fe-common/silc/module-formats.[ch],
2716 irssi/src/fe-common/silc/core/client_ops.c.
2718 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Fixed a security problem found in SKE. The initiator's
2721 public key too is now added to the HASH hash value creation
2722 which is signed by the responder to create the SIGN value.
2723 This will prevent anyone in the middle to lie to the responder
2724 about the initiator's public key. If this is done now, the
2725 man in the middle will get caught. Updated the protocol
2728 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2730 * Better installation directory handling. Configure module
2731 paths and other paths automatically to example_silc* files
2732 in doc/. A patch by toma.
2734 * Fixed compiler warning from MPI library, and from SILC RNG.
2737 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2738 It can be configured with ./configure. A patch by toma.
2740 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Find correct make to use in prepare-clean. A patch by
2743 toma. Affected file prepare-clean.
2745 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2747 * Added irssi variables use_auto_addr, auto_bind_ip,
2748 auto_bind_port and auto_public_ip.
2750 * Changed the interface for silc_client_send_key_agreement
2751 in lib/silcclient/silcapi.h
2755 irssi/src/silc/core/silc-core.c
2757 lib/silcclient/silcapi.h
2758 irssi/src/silc/core/silc-channels.c
2759 lib/silcclient/client_keyagr.c
2762 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Added silc_pkcs_public_key_compare to compare two
2765 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2767 * Check that the client who set the founder mode on the
2768 channel is the same client that is giving the founder
2769 mode to itself. It is done by comparing the saved public
2770 key (it is saved even in the authentication is passphrase).
2771 Affected file silcd/command.c.
2773 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Do not process packet for disconnected socket connection.
2776 Affected file lib/silccore/silcpacket.c.
2778 * Process the DISCONNECT packet through scheduler in the
2779 client library. Affected file lib/silcclient/client.c.
2781 * Fixed the silc_client_packet_parse to not to increase
2782 the packet sequence number if the conn->sock and the
2783 current socket connection is not same. This can happen
2784 for example during key agreement when the conn includes
2785 multiple socket connections (listeners). Affected file
2786 lib/silcclient/client.c.
2788 * The sender of the file transfer request now provides also
2789 the pointer (listener) for the key exchange protocol. If
2790 the listener cannot be created then it sends empty key
2791 agreement and lets the receiver provide the listener.
2793 Added `local_ip' and `local_port' arguments to the
2794 silc_client_file_send. If they are provided they are used,
2795 if not then it will attempt to find local IP address, if
2796 not found or bind fails then the remote client will provide
2799 Affected files are lib/silcclient/client_ftp.c and
2800 lib/silcclient/silcapi.h.
2802 * Extended the FILE SEND command to support defining the
2803 local IP and port for key exchange listener. They are
2804 optional. Affected file irssi/src/silc/core/silc-servers.c.
2806 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2808 * Defined to WHOIS command reply the sending of fingerprint
2809 of the client's public key (if the proof of posession of the
2810 corresponding private key is verified by the server).
2811 Updated to the protocol specification.
2813 * Added support of receiving the client's public key's
2814 fingerprint in command reply in client library. Affected
2815 file is lib/silcclient/command_reply.c, and
2816 lib/silcclient/idlist.[ch].
2818 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Do not send over 128 chars long nickname to the server
2821 in NICK command. Affected file lib/silcclient/command.c.
2823 * Do not send over 256 chars long channel names to the server
2824 in JOIN command. Affected file lib/silcclient/command.c.
2826 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Assure that silc_server_close_connection cannot be called
2829 twice for same socket context. Affected file is
2832 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Send error message to application if opening file for
2835 writing during file transfer fails. Affected file is
2836 lib/silcclient/client_ftp.c.
2838 Remove all file transfer sessions for a client that we're
2839 removing from ID cache.
2841 Affected file is lib/silcclient/client_ftp.c.
2843 * Fixed silc_net_addr2bin to return correct address. Affected
2844 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2846 * Fixed file transfer session removing on signoff notify.
2847 Affected file irssi/src/silc/core/silc-servers.c.
2849 * Added the SilcClientFileError to be returned in the monitor
2850 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2851 Affected file lib/silcclient/silcapi.h.
2853 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2855 * Fixed a crash in silc_client_ftp_free_sessions and
2856 silc_client_ftp_session_free_client. Affected file
2857 lib/silcclient/client_ftp.c.
2859 * Added `disabled' field in the SilcChannelEntry in the server
2860 to indicate if the server entry is disabled. Affected file
2861 silcd/idlist.h, silcd/command[_reply].c.
2863 * SILC server adds now /var/run/silcd.pid everytime it is
2864 started. Affected file silcd/silcd.c.
2866 * Added silc_server_packet_send_clients to send a packet to
2867 the provided table of client entries. Affected file
2868 silcd/packet_send.[ch].
2870 * Fixed a crash in client resolving in client_prvmsg.c in
2871 client library. Affected file lib/silcclient/client_prvmsg.c.
2873 * Do not actually remove the client directly from ID cache
2874 during SERVER_SIGNOFF, but invalidate it. This way we
2875 preserve the WHOWAS info for the client. Affected file
2876 silcd/server_util.c.
2878 * Fixed SERVER_SIGNOFF notify handling in the server. The
2879 server is now able to process incoming SERVER_SIGNOFF notify
2880 for a server that it doesn't even know about. It will remove
2881 the clients provided in the notify. Affected file
2882 silcd/packet_receive.c.
2884 * Check for partial packet in data queue after every packet that
2885 was found from the queue. Return and wait for more data if
2886 there is partial data in queue. Affected file is
2887 lib/silccore/silcpacket.c.
2889 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * Added SilcClietFileError enum to indicate error in
2892 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2893 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2894 Affected files lib/silcclient/silcapi.h and
2895 lib/silcclient/client_ftp.c.
2897 * Check that newsize in silc_buffer_realloc is larger than
2898 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2900 * Added better monitor of file transfers. It now monitors
2901 key agreement protocol during the file transfer too. Added
2902 error reporting too. Affected files
2903 irssi/src/silc/core/silc-servers.c,
2904 irssi/src/fe-common/silc/module-formats.[ch].
2906 * Wrote a help file for FILE command.
2908 * Added silc_rng_global_get_byte_fast to get not-so-secure
2909 random data as fast as possible. Random data is read from
2910 /dev/urandom if available and from the SILC RNG if not
2911 available. It is used in padding generation. Affected file
2912 lib/silccrypt/silcrng.[ch].
2914 * All packets in client library are now processed synchronously.
2915 Optimized packet processing a lot. Affected file
2916 lib/silcclient/client.c.
2918 * All server connection packets are processing synchronously
2919 now in server, to optimize packet processing. Affected file
2922 * Include files are installed now only in Toolkit distribution
2923 if make install is given. Affected files: all Makefile.am's.
2925 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Assure that silc_client_notify_by_server_resolve does not
2928 resolve the client information multiple times. If it cannot
2929 be found by the first it cannot be found at all. Affected
2930 file lib/silcclient/client_notify.c.
2932 * Fixed WHOWAS command reply calling. Affected file
2933 lib/silcclient/command_reply.c.
2935 * Removed all references to silc_idlist_get_client from the
2936 Irssi SILC client since that call is internal call used by
2937 the library. The Irssi SILC client will use now client
2938 retrieval functions found in silcapi.h.
2940 * Fixed a bug in resolving nickname info before sending
2941 private message. It used freed memory. Affected file
2942 irssi/src/silc/core/silc-servers.c.
2944 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Assure my_channels statistics cannot go negative in server.
2947 Affected files silcd/server.c, silcd/server_util.c.
2949 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2953 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Win32 Toolkit changes. Affected files

2959 lib/sftp/sftp_fs_memory.c.
2961 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Added silc_net_localip to return local host's IP address.
2964 Affected file lib/silcutil/silcnet.[ch].
2966 * If key exchange or rekey protocol is active for a connection
2967 parse all packets syncronously since there might be packets
2968 in packet queue that we are not able to process without first
2969 processing packets before them. Affected file silcd/server,
2970 lib/silcclient/client.c.
2972 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2973 whether library should continue processing the packet.
2974 Affected file lib/silccore/silcpacket.h.
2976 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2977 SilcSFTPMonitorData to SFTP server to monitor various
2978 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2979 lib/silcsftp/sftp_server.c.
2981 * Added silc_file_size to return file size. Affected file
2982 lib/silcutil/silcutil.[ch].
2984 * Implemented the file transfer support for the client library.
2985 Added preliminary support for simple client to client one-file
2986 transmission. Affected file lib/silcclient/client_ftp.c,
2987 lib/silccilent/client.[ch].
2989 * Added new local command FILE to the Irssi SILC Client.
2990 It is used to perform the file transfer. It has subcommands
2991 SEND, RECEIVE, SHOW and CLOSE. Affected files
2992 irssi/src/silc/core/client_ops.c,
2993 irssi/src/silc/core/silc-server.[ch].

3002 * Renamed silc_file_read and silc_file_write to functions
3003 silc_file_readfile and silc_file_writefile. Added function
3004 silc_file_open and silc_file_close. Affected files
3005 lib/silcutil/silcutil.[ch].
3007 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Resolve the client info when received private message or
3010 channel message for a client which nickname we don't know.
3011 Affected files lib/silcclient/client_prvmsg.c and
3012 lib/silcclient/client_channel.c.
3014 * Do not crash in /KEY if client is not connected. Affected
3015 file irssi/src/silc/core/silc-channels.c.
3017 * Added SilcClientStatus field to the SilcClientEntry in the
3018 lib/silcclient/idlist.h.
3020 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3021 is incomplete and is being resolved, it won't be resolved
3024 Make sure also that USERS command reply does not resolve
3025 twice information. Affected file is
3026 lib/silcclient/command_reply.c.
3028 Make sure that silc_client_get_clients_by_list does not
3029 resolve twice same information.
3031 * Check for valid client->id in the silc_server_free_client_data.
3032 Affected file silcd/server.c.
3034 * Fixed /GETKEY nick@server not to crash if the server entry
3035 is not found. Affected file lib/silcclient/command.c.
3037 * Fixed the silc_server_check_cmode_rights to check the
3038 requested modes correctly. Affected file silcd/command.c.
3040 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Better checks for non-printable chars in nick added.
3043 Affected file silcd/command.c.
3045 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Call the silc_server_udpate_servers_by_server in the
3048 primary router that comes back online in the backup resuming
3049 protocol. Otherwise it routes packets wrong. Affected file
3050 silcd/server_util.[ch], silcd/server_backup.c.
3052 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3055 lib/silcutil/silcbuffmt.[ch].
3057 * Redefined the SILC packet header to include the padding
3058 length. Affected file lib/silccore/silcpacket.[ch].
3060 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3061 length for maximum padding up to 128 bytes). Affected
3062 file lib/silccore/silcpacket.h.
3064 * Removed all backwards support for old 0.5.x MAC thingies.
3065 The SILC packet header change makes it impossible to be
3066 backwards compatible.
3068 * Send the ENDING packet with timeout in the backup resuming
3069 protocol. This is to assure that all routers has connected
3070 to the primary router. Affected file silcd/server_backup.c.
3072 * Changed the RNG to take the first IV from random data. It
3073 used to take it from zero actually. Changed the RNG also
3074 to use /dev/urandom during session. /dev/random is used
3075 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3077 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Changed the SILC packet header to have the first two bytes
3080 (the packet length) encrypted. Affected files aroung the
3081 code tree, lib/silccore/silcpacket.[ch]. Removed the
3082 SilcPacketCheckDecrypt callback. It is not needed anymore
3083 since the silc_packet_receive_process will determine now
3084 whether the packet is normal or special.
3086 * Implemented the unidirectional MAC keys. Affected files
3087 lib/silcske/silcske.c, silcd/protocol.c and
3088 lib/silcclient/protocol.c.
3090 * Implemented the packet sequence number to the MAC computation.
3091 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3092 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3093 lib/silcclient/protocol.c.
3095 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Allow backup router to announce servers. All servers
3098 announced by backup router are added to the global list
3099 automatically. Update hte server's socket to our primary
3100 router also when backup router announces a server.
3101 Affected file silcd/packet_receive.c.
3103 * Do not update the client->router in the function
3104 silc_server_udpate_clients_by_server if the client is on
3105 global list. We might fail to find any specific server
3106 for locally connected clients and local cell clients. They
3107 should still use the `from' and not `to' as client->router.
3108 This fixes backup router resuming protocol. Affected file
3109 silcd/server_util.c.
3111 * Decrease channel statistics count only if the channel
3112 deletion worked. Affected files are silcd/server.c and
3113 silcd/server_util.c.
3115 * Added silc_server_update_servers_by_server to update origin
3116 of all server entries. Used during backup router protocol.
3117 Affected files silcd/server_util.[ch], silcd/server.c. and
3118 silcd/backup_router.c.
3120 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3121 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3122 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3123 lib/silccrypt/silchmac.c.
3125 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Assure that router cannot reroute the same channel message
3128 to the sender. Affected file silcd/packet_receive.c.
3130 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3132 * Made better checks that the channel message is not sent
3133 to the router it came from. Affected file is
3134 silcd/packet_send.c. Fixed memory leak too.
3136 * Announce informations for incoming router connection, but
3137 only after checking if it is replaced by backup router.
3138 Affected file silcd/packet_receive.c.
3140 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Fixed the backup resuming protocol to work in multiple
3143 router environment. Affected file silcd/server_backup.c.
3145 * Route packet only to one router in the function
3146 silc_server_packet_send_to_channel. Affected file is
3147 silcd/packet_send.c.
3149 * Fixed silc_server_send_notify_dest to set the broadcast
3150 flag. Fixed the silc_server_send_notify_topic to actually
3151 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3152 Affected file silcd/packet_send.c.
3154 * Changed the SFTP Filesystem interface. Changed the
3155 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3156 the filesystem operation function. The SilcSFTPFilesystem
3157 is now a context that is allocated by all filesystem allocation
3158 functions and it already includes the operations structure
3159 and filesystem specific context. It is given as argument
3160 now to the silc_sftp_server_start. This made the interface
3161 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3162 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3164 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Changed the backup router adding and getting interfaces
3167 in the server. The router that will be replaced by the
3168 specified backup router is now sent as argument. Affected
3169 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3172 * Added silc_net_addr2bin_ne to return the binary form of
3173 the IP address in network byte order. Affected files
3174 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3176 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Check for existing server ID in silc_server_new_server
3179 and in silc_server_connect_to_router_final and remove the
3180 old entry if it exists. Affected file silcd/packet_receive.c,
3183 * Send the channel message always to only one router, either
3184 in upstream or downstream. Affected file is
3185 silcd/packet_send.c.
3187 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Wrote the definition of the backup resuming protocol to the
3190 protocol specification.
3192 * Removed one redundant channel key generation from normal
3193 server during joining procedure. Removed one redundant
3194 channel key sending from server to router during joining
3195 procedure. Affected file silcd/command.c.
3197 * Made minor bugfixes to the backup router resuming protocol.
3198 Affected file silcd/server_backup.c, server.c.
3200 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Added --disable-asm configuration option. Affected files
3203 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3206 * Implemented the backup resuming protocol that is used to
3207 resume the primary router position in the cell after the
3208 primary router comes back online. Affected files
3209 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3210 and silcd/server_util.[ch].
3212 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Sleep two (2) seconds after sending QUIT command to server.
3215 Affected file lib/silcclient/command.c.
3217 * Assure that if outgoing data buffer is pending do not force
3218 send any data. Affected file silcd/packet_send.c.
3220 * Assure that if outgoing data buffer is pending do not force
3221 send any data. Affected file lib/silcclient/client.c.
3223 * Implemented the backup router support when the primary router
3224 goes down. The servers and routers can now use the backup
3225 router as new primary router without loosing connectivity.
3227 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3230 in the server to indicate disabled entry. All data read
3231 from the connection will be ignored and no data is sent
3232 for entry that is disabled. Affected files are
3233 silcd/idlist.h, silcd/server.c.
3235 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3237 * Created SFTP client and server test programs in the
3238 lib/silcsftp/tests directory.
3240 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * Implemented memory filesystem (virtual filesystem) for
3243 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3246 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Implemented the SFTP (SSH File Transfer Protocol) to the
3249 lib/silcsftp. It includes SFTP client and SFTP server
3252 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Moved lib/silccore/silcprotocol.[ch] to the
3255 lib/silcutil library.
3257 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3258 take variable argument list pointer as argument. Affected
3259 file lib/silcutil/silcbuffmt.[ch].
3261 * Added silc_buffer_set function that is used to set data
3262 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3263 Affected file lib/silcutil/silcbuffer.h.
3265 * Changed various routines in the core library to use the new
3266 silc_buffer_set instead of allocating new buffer only for
3269 * Added 64-bit value formatting and unformatting support to the
3270 silc_buffer_[un]format routines. Affected file is
3271 lib/silcutil/silcbuffmt.[ch].
3273 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3274 to includes/bitmove.h.
3276 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Fixed channel user mode saving in client library. Affected
3279 file lib/silcclient/command[_reply].c.
3281 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Defined the file transfer to the SILC Protocol. Added
3284 new packet type SILC_PACKET_FTP and defined File Transfer
3285 Payload. The mandatory file transfer protocol is SFTP
3286 (SSH File Transfer Protocol). Affected file in addition
3287 of the internet draft is lib/silccore/silcpacket.h.
3289 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3290 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3291 is used as part of backup router protocol when the primary
3292 router of the cell is back online and wishes to resume
3293 the position as primary router.
3295 * Redefined the MAC generation keys in the protocol. The
3296 same key is not used anymore in both direction. Both
3297 direction will now use different keys for sending and
3298 receiving. This fixes a potential security flaw. This
3299 change causes incompatibilities in the protocol.
3301 * Redefined also the MAC computation from the packet.
3302 An packet sequence number is now added to the MAC
3303 computation. This prevents possible replay attacks against
3304 the protocol. This change too causes incompatibilities
3307 Added `sequence' field to the SilcPacketContext to hold
3308 the current sequence number for the packet.
3310 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Added `created' field to the SilcIDListData in the file
3313 silcd/idlist.h to indicate the time when the entry was
3316 * Added `created' field to the SilcChannelEntry too. Affected
3317 file silcd/idlist.h.
3319 * Added `creation_time' aguments to all the announcement functions
3320 in the server. If it is provided then only the entries that
3321 was created after the provided time frame are actually
3322 announced. Affected file silcd/server.[ch].
3324 * The protocol says that the Channel ID's IP address must be
3325 based on the router's IP address. Added check for this in
3326 the silc_server_new_channel when processing incoming New Channel
3327 Payload. Affected file silcd/packet_receive.c.
3329 * Print out the correct version with --version in SILC client.
3330 Affected file irssi/src/silc/core/silc-core.c.
3332 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * Fixed WHOWAS command to check for completnes of the client
3335 entry always, not just when the command is coming from client.
3336 Affected file silcd/command.c.
3338 * Added new function silc_server_packet_queue_purge to purge the
3339 outgoing data queue to the network. After the function returns
3340 it is guaranteed that the outgoing packet queue is empty.
3341 Affected file silcd/packet_send.[ch].
3343 * Purge the outgoing packet queue in the rekey protocol's final
3344 callback to assure that all rekey packets go to the network
3345 before quitting the protocol. Affected file silcd/server.c.
3347 * Added silc_client_packet_queue_parse as similar function as
3348 in server to the client library. The affected file is
3349 lib/silcclient/client.c.
3351 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Splitted silcd/server.c and created silcd/server_util.[ch]
3354 for utility functions.
3356 * Added new socket flag SILC_SF_DISABLED to indicate that the
3357 connection is open but nothing can be sent to or received from
3358 the connection. Affected file lib/silcutil/silsockconn.[ch].
3359 The checking for disabled socket is checked in the low level
3360 silc_socket_write and silc_socket_read functions.
3362 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Allow only nicknames and channel names that fits into the
3365 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3367 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * When processing JOIN command reply in server check that if
3370 the channel exists in our global list we'll move it the local
3371 list. Affected file silcd/command_reply.c.
3373 * Fixed the check whether client is joined on the channel already
3374 in JOIN command. Affected file lib/silcclient/command.c.
3376 * Fixed the JOIN command reply to check whether the channel
3377 already exists. Affected file lib/silcclient/command_reply.c.
3379 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Added silc_ske_status_string to map the SKE error numbers
3382 to readable strings. The affected files are
3383 lib/silcske/silcske[_status].[ch].
3385 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Do not show the private channels on the WHOIS channel list
3388 as it is not allowed by the protocol. The affected file is
3391 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Assure that the packet length digged from the actual packet
3394 is something sensible in the silc_packet_decrypt_rest_special
3395 in lib/silccrypt/silcpacket.c.
3397 * Free and NULL the allocated pointer in silc_hmac_alloc if
3398 the HMAC allocation fails. The affected file is
3399 lib/silccrypt/silchmac.c.
3401 * Print the selected security properties to the log files in
3402 the server. Affected file silcd/protocol.c.
3404 * Add SKE's reference counter even if calling the completion
3405 callback manually. Otherwise it goes negative, although it
3406 does not cause any problems. The affected file is
3407 lib/silcske/silcske.c.
3409 * Remove the client entry with short timeout after giving the
3410 KILL command. Affected file lib/silcclient/command.c.
3412 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3413 case all found clients are already disconnected (WHOWAS would
3414 found them) in the server. Affected file silcd/command.c.
3416 * Update the last_receive (time of last data received) to be
3417 updated only when received private or channel message so that
3418 the idle time showed in WHOIS makes more sense.
3420 * Added boolean field `valid' in to the SilcClientEntry in the
3421 client library to indicate whether the entry is valid or not.
3422 This fixes the nickname change bug on channel when changing
3423 the nickname to be same than the old (like nick to Nick) the
3424 nickname formatter doesn't set the new nick anymore to Nick@host.
3425 Affected file lib/silcclient/idlist.[ch].
3427 * Now actually fixed the nickname changing on disconnection.
3428 Added new function silc_change_nick to the Irssi SILC Client.
3429 Affected file irssi/src/silc/core/client_ops.c,
3430 irssi/src/silc/core/silc-nicklist.[ch].
3432 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Check that the public key exists in the GETKEY command before
3435 trying to encode it. Affected file silcd/command.c.
3437 * Print some notifications on received public keys with GETKEY
3438 command in the Irssi SILC Client. Affected files are
3439 irssi/src/fe-common/silc/module-formats.[ch],
3440 irssi/src/silc/core/client_ops.c.
3442 * Use IDENTIFY command to resolve the server information in the
3443 GETKEY command instead of INFO command. Affected file
3444 lib/silcclient/command.c.
3446 * All command reply functions in the client library now calls
3447 the pending command reply callbacks even if an error has
3448 occurred. The server has done this a long time and now it was
3449 time to move the client library to this as well. Now all
3450 errors can be delivered back to the pending command reply
3451 callbacks if necessary. Affected files are
3452 lib/silcclient/command[_reply].[ch].
3454 * Change the nickname on disconnection back to the username
3455 because in reconnect the server will enforce it to it anyway.
3456 Affected file irssi/src/silc/core/silc-servers.c.
3458 * Fixed a config file parsing bug in the Irssi SILC client.
3459 Affected file irssi/src/silc/core/clientconfig.c.
3461 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * When printing the channel mode on JOIN, verify that the
3464 channel key and channel's HMAC are valid. Affected file
3465 irssi/src/silc/core/client_ops.c.
3467 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3470 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3471 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3473 * Removed channel key rekey task deleting from the function
3474 silc_server_save_channel_key. Affected file silcd/server.c.
3475 Added explicit timeout task context instead that is used to
3476 delete the task if we are registering a new task before the
3477 new task has elapsed.
3479 * When channel key rekey occurs the client library now saves
3480 the old channel key for a short period of time (10 seconds) and
3481 is able to use it in case some is still sending channel
3482 messages encrypted with the old key after the rekey. Affected
3483 file lib/silcclient/[idlist.h|client_channel.c].
3485 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Added check to the silc_server_new_id_real to not accept
3488 new ID if it is the sender's own ID. Affected file is
3489 silcd/packet_receive.c.
3491 * Assure that we do not announce ourself or the one we've
3492 sending our announcements when we're router and are announcing
3493 servers to our primary router. Affected file silcd/server.c.
3495 * Fixed silc_server_command_identify_check_client to assemble
3496 correct WHOIS packet. It send corrupted WHOIS packet and
3497 caused problem with router to router connections. Affected
3498 file silcd/command.c.
3500 Fixed also silc_server_command_whois_check the same way
3501 as for the IDENTIFY command.
3503 * Added new SilcIDListStatus to the server in the SilcIDListData
3504 structure. The status now includes the current status of
3505 the entry (like registered, resolved etc.). Affected file
3506 silcd/idlist.[ch]. Defined a bunch of different status types
3507 as well. This replaced the old boolean registered field as well.
3509 Added resolve_cmd_ident field to the SilcClientEntry structure
3510 too so that if the entry is for example being resolved so
3511 another command may attach to the same pending command reply
3512 without requiring to resolve the same entry again. This concept
3513 should optimize the WHOIS and the IDENTIFY resolving under
3514 heavy load by taking away unnecessary resolving for entries
3515 that are being resolved already.
3517 Added support for adding multiple pending commands for one
3518 command idenfier. Affected file silcd/command[_reply].[ch].
3520 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3521 before deleting the data. Otherwise the hash table will have
3522 freed data in comparison functions. Affected file is
3523 silcd/command_reply.c.
3525 * Fixed silc_idlist_replace_client_id to add the new entry to
3526 the cache with NULL nickname. Otherwise there will be invalid
3527 memory as the nickname after the nickname is freed. Affected
3528 file silcd/packet_receive.c.
3530 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3531 saved into wrong slots because the previous number of entries
3532 was not taken into account. Affected file silcd/idlist.c.
3533 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3535 * If we are router and we receive JOIN notify to a channel that
3536 does not have any users then notified client is marked as the
3537 channel founder, as it is it. The affected file is
3538 silcd/packet_receive.c
3540 * Added to the extended hash table API's table_del_*ext functions
3541 the destructor as argument too, so that the caller can decide
3542 which destructor to use or whether to use destructor at all.
3543 Affected file lib/silcutil/silchashtable.[ch].
3545 * Fixed ID Cache purging. It actually deleted the entries from
3546 the hash table after the data was freed. The hash table ended
3547 up comparing freed memory. The affected file is
3548 lib/silccore/silcidcache.c.
3550 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3552 * Fixed Irssi SILC client's KILL command's HELP syntax.
3554 * The USERS command now resolves the detailed user information
3555 if the userinfo field is missing. Affected file is
3556 lib/silcclient/command_reply.c.
3558 * Do not print error in silc_file_read if the read file does
3559 not exist. Just silently return NULL. Affected file is
3560 lib/silcutil/silcutil.c.
3562 * Fixed the silc_log_output to not wine about NULL filename
3563 and to not create some bogus " " filename. Affected file is
3564 lib/silcutil/silclog.c.
3566 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3568 * Fixed various printing bugs on the user interface in the
3569 Irssi SILC Client. Minor changes that were forgotten from
3572 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Fixed the configure.in.pre and the compilation and distribution
3575 environment to support the new autoconf 2.52. That version is
3576 now required to compile the CVS trunk.
3578 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3580 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3581 to generally parse user@fqdn format strings. Affected file
3582 lib/silcutil/silcutil.c.
3584 * Added nickname_format and nickname_force_format fields to the
3585 SilcClientParams structure. The first one defines the format
3586 for the nicknames that the library will enforce if the receives
3587 multiple same nicknames. The second one is boolean value and
3588 can be used to force the library to always enforce the format
3589 to the nicknames regardles whether there are multiple nicknames
3590 or not. This configurable formatting was employed to flexibly
3591 support accessing multiple nicknames from the user interface.
3592 The userinterface can now set the nicknames to what ever format
3593 they prefer. Affected file lib/silcclient/silcapi.h.
3595 Added function silc_client_nickname_format to the file
3596 lib/silcclient/idlist.c. It performs the nickname formatting.
3598 Added new field `hostname´ to the SilcClientEntry context.
3599 It holds the hostname of the client. Affected file is
3600 lib/silcclient/idlist.h.
3602 * Irssi SILC Client sets the nicknames in nick@hostn format.
3603 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3604 irssi/src/silc/core/silc-core.c.
3606 The WHOIS printing now also shows both the real nickname and
3607 the formatted nickname so that user knows how to access the
3608 user if there are multiple same nicknames cached. Affected
3609 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3610 printing formatting too to take the hostname now as a separate
3611 argument. The Affected file is
3612 irssi/src/fe-common/silc/modules-formats.[ch].
3614 * Changed the silc_client_get_clients_local to accept the formatted
3615 nickname as argument. It accepts the real nickname too but the
3616 formatted nickname can be used to find the true entry from
3617 multiple entries. Affected file lib/silcclient/silcapi.h and
3618 lib/silcclient/idlist.c.
3620 * Added nickname_format_parse field to the SilcClientParams.
3621 It is a callback function provided by the application to parse
3622 the nickname out of the formatted nickname string. The library
3623 calls it to get the nickname from the formatted string. Since
3624 the application generally knows better the format of the nickname
3625 string it parses it instead of the library, even though library
3626 encodes the formatted string. If the callback function is not
3627 provided then the library will use the string as is. The
3628 affected file is lib/silcclient/silcapi.h.
3630 * All the nickname strings passed to the client library in
3631 commands are now expected to be formatted nickname strings.
3632 If the command does not support the formatted nickname string
3633 it will assume that the sent string is the actual nickname.
3634 Affected file lib/silcclient/command.c.
3636 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Added public key authentication support to OPER and SILCOPER
3639 commands in the client library. Affected file is
3640 lib/silcclient/command.c.
3642 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * Changed the get_auth_methdod client operation to be asynchronous.
3645 It can be async if the application resolves the authentication
3646 method from the server during the negotiation. Added new
3647 SilcGetAuthMeth completion callback that the application will
3648 call after resolving the authentication method.
3650 Added function silc_client_request_authentication_method that
3651 the application can use to resolve the authentication method
3652 from the server. Added also SilcConnectionAuthRequest callback
3653 that the library will call after the server has replied. The
3654 application can call this function if it does not know the
3655 current authentication method.
3657 Affected files are lib/silcclient/client.c and
3658 lib/silcclient/silcapi.h.
3660 * The Irssi SILC client now automatically resolves the authentication
3661 method incase any configuration information is not present (and
3662 currently there never is). The affected file is
3663 irssi/src/silc/core/client_ops.c.
3665 * Fixed public key authentication from the client library.
3666 Affected file lib/silcclient/protocol.c. Changed also the
3667 protocol specification about the public key authentication in
3668 the connection authentication protocol. The actual data to be
3669 signed is now computed with a hash function before signing.
3671 * Fixed the public key authentication from the server as well.
3672 Affected file silcd/protocol.c.
3674 * Removed the mlock()'s from the memory allocation routines.
3675 Affected file lib/silcutil/silcmemory.c. The ./configure does
3676 not check anymore for the mlock(). Affected file is
3679 * Fixed USERS command in server to allow the execution of the
3680 command for private and secret channels if the client sending
3681 the command is on the channel. Affected file silcd/command.c.
3683 * Fixed silc_client_get_clients_local to return the clients
3684 count correctly. It could return wrong value. Affected file
3685 lib/silcclient/idlist.c.
3687 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3689 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3690 types. The assembler optimizations seemed not to like 64-bit
3691 data types. The assmebler optimizations thus are now enabled
3692 also for BSD systems as opposed to only enable them for Linux.
3694 * Do not check for threads at all on BSD systems. Affected
3695 file configure.in.pre.
3697 * Removed -n and -h options from the Irssi SILC Client since
3698 they are not used in silc.
3700 * Fixed the prime generation to assure that the first digit
3701 of the generated random number is not zero since our conversion
3702 routines does not like number strings that starts with zero
3703 digit. If zero digit is seen the random number is regenerated.
3704 This caused some corrupted RSA keys when the zero first digit
3705 was met. Affected file lib/silcmath/silcprimegen.c.
3707 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3709 * Fixed WIN32 configuration in the ./configure script.
3710 Fixed to include xti.h on environments that has it.
3711 Patches by Carsten Ilchmann and andrew.
3713 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3715 * Changed the silc_id_create_client_id to be collision
3716 resistant. It is now assured that there cannot be created
3717 two same client ID's. I suspect that some weird bugs in
3718 the server were actually caused by duplicate Client IDs.
3719 Affected file silcd/serverid.[ch]. A router receiving
3720 new ID now also assures and informs the sending server
3721 if the ID caused collision.
3723 * Changed the silc_id_create_channel_id to also assure that
3724 there are no collisions.
3726 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * Statement about ignoring the Mutual Authentication flag when
3729 performing rekey with PFS was a bit misleading. It is ignored
3730 if it was set in the initial negotiation, it cannot be even
3731 set in the rekey. Fixed in the ke-auth draft. Started the
3732 new versions of the protocol drafts in the doc/.
3734 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Fixed a bug in silc_client_command_identify_save when saving
3737 new channel information. The channel name was no duplicated
3738 and caused crash on exit. Affected file is
3739 lib/silcclient/command_reply.c.
3741 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Fixed the getkey command handling in the server. Send just
3744 empty OK reply to the sender if the key could not be fetched
3745 (but everything else was ok, like the key just was not available).
3746 Changed the public key parameter to optional in the protocol
3747 specs so that empty OK reply can be sent. Affected file
3750 Added a message to Irssi SILC client to tell to user if the
3751 server did not return a public key.
3753 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3755 * Fixed a channel key regeneration bug. It registered new
3756 timeout tasks exponentially until all system resources were
3757 used. Affected file silcd/server.c.
3759 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3761 * Added the SILC Document generator to the scripts/silcdoc.
3762 It can be used to generate the Toolkit Reference Manual out
3763 of the source tree. Internally it will also use the RoboDoc
3764 generator now imported in util/robodoc.
3766 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Added couple of return's in rekey protocol if error orccurred
3769 during the protocol. The execution must be terminated.
3770 Affected file silcd/protocol.c. Also, terminate the protocol
3771 always with timeout.
3773 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * The client's Client ID was created initally from the wrong
3776 nickname (it could have been in format nick@host) in the
3777 silc_server_new_client. Affected file silcd/packet_receive.c
3779 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Added some SILC_LOG_ERROR's to various error conditions
3782 if client could not be added to ID cache. Affected files
3783 silcd/packet_receive.c and silcd/server.c.
3785 * When client's sock->user_data is freed, NULL also the
3786 client->router and client->connection pointers. Added check
3787 for these pointers being NULL to various places around the
3788 code. Affected file silcd/server.c.
3790 * Added client->data.registered == TRUE checks to various
3791 places around the code to assure that unregistered client's
3792 are not handled when it is not allowed. Affected file
3795 * Added `bool registered' fields to all
3796 silc_idlist_[server|client]_get_* routines to indicate whether
3797 the fetched client needs to be registered or not. Affected
3798 file silcd/idlist.[ch].
3800 * Add your own entry as registered to the ID cache in the
3801 server. Affected file server.c.
3803 * Fixed a bug in silc_server_new_server. The SilcServer was
3804 set as the new server's context instead of SilcServerEntry.
3805 This naturally caused some weird bugs.
3807 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * Do not delete the channel rekey task when adding it
3810 for in silc_server_create_channel_key.
3812 * Changed the silc_server_create_channel_key to return
3813 TRUE or FALSE to indicate the success of the channel key
3816 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3818 * Fixed MSVC++ project files and added missing files to
3819 Makefiles under win32/.
3821 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Do not add TCP_NODELAY flag if the operating system
3824 does not have it defined. Affected files are
3825 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3827 * Fixed buffer overflow from Irssi SILC Client. Affected
3828 file irssi/src/fe-common/core/themes.c.
3830 * Fixed double free in client library in the file
3831 lib/silcclient/client.c when disconnecting from server.
3833 * Applied double free patch from cras to Irssi SILC client.
3834 Affected files irssi/src/core/[modules/expandos].c
3836 * Fixed the disconnection handling to Irssi SILC Client.
3837 The application must call silc_client_close_connection
3838 in ops->connect client operation in case of failure of
3839 the connection. Affected file is
3840 irssi/src/silc/core/client_ops.c.
3842 * Do not set sock->protocol to NULL in the function
3843 silc_client_close_connection after executing the protocol's
3844 final callback since the sock might not be valid anymore.
3845 Affected file lib/silcclient/client.c.
3847 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3849 * Do not enable SILC_THREADS if the linking with libpthread
3850 did not happen. Affected file configure.in.pre.
3852 * Added notion to protocol specification that server must
3853 verify the sent authentication payload with CMODE when
3854 setting the channel founder key. Implemented it to the
3855 server. Affected file silcd/command.c.
3857 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3859 * Added _EXTRA_DIST SILC distribution variable to the
3860 distributions file. It is used to conditionally add extra
3861 files or directories to the specific distribution. Affected
3862 files ./prepare, Makefile.am.pre and distributions.
3864 Removed the `_' from the start of the distribution names.
3867 * Added README.WIN32 for instructions to compile the Toolkit
3870 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3872 * Fixed a double free in disconnection in the server. Affected
3873 file is silcd/server.c.
3875 * Fixed the lib/silcske/groups.c to work now also with GMP
3876 MP library. The string conversion did not work when using
3877 specific base and the base is indicated in the string as well.
3879 * Created win32/ directory which now includes MSVC++ specific
3880 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3881 It will appear only in the toolkit distribution
3883 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3885 * Changed the key material distribution function in case when
3886 the hash output is too short. The data is now concatenated
3887 a bit differently than it used to. Made the change to the
3888 SKE protocol specification.
3890 * Added better GMP detection to configure.in.pre. A patch
3893 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Fixed a minor bug in SKE that might cause some problem on
3896 some platforms. Affected file lib/silcske/silcske.c.
3898 * Added the cookie checking for initiator in the SKE. It checks
3899 that the responder returns the sent cookie unmodified. The
3900 affected file is lib/silcske/silcske.c. Added new SKE
3901 error type INVALID_COOKIE that can be sent during the
3902 negotiation. Fixed some memory leaks as well.
3904 * Added the "invalid cookie" error message to Irssi SILC client's
3907 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3909 * Added `task_max' field to the SilcClientParams to indicate
3910 the maximum tasks the scheduler can handle. If set to zero,
3911 default values are used. Affected file lib/silcclient/silcapi.h.
3913 * Fixed memory leaks in silc_client_close_connection. Affected
3914 file lib/silcclient/client.c.
3916 * Added silc_client_del_client_entry to client library to free
3917 all memory of given client entry. Affected file is
3918 lib/silcclient/idlist.[ch].
3920 * Added new functions silc_client_del_channel and
3921 silc_client_del_server to delete channel and server entries.
3922 Affected file lib/silcclient/[silcapi.h/idlist.c].
3924 * Removed silc_client_del_client_by_id from silcapi.h.
3926 * Fixed the INFO command to return the server's own info
3927 correctly when querying by Server ID. Affected file is
3930 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3932 * Removed the non-blocking settings in WIN32 code in the
3933 silc_sock_[read/write] and added SleepEx instead. Affected
3934 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3935 of input data is now checked with FIONREAD and ioctlsocket.
3937 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3939 * Call silc_schedule_task_del_by_context in the
3940 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3941 Affected file lib/silccore/silcprotocol.c.
3943 * Call silc_protocol_cancel for active protocols in the
3944 silc_server_close_connection if the funtion
3945 silc_server_free_sock_user_data has not been called.
3946 Affected file silcd/server.c.
3948 * Generic tasks cannot be deleted using the del_by_fd
3949 task deleting function since generic tasks does not match
3950 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3952 * Added a notion to SILCOPER help file that the SILCOPER works
3953 only on router server, not on normal server.
3955 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3957 * Added for WIN32 support for the new scheduler as well.
3958 Affected file lib/silcutil/win32/silcwin32schedule.c.
3960 * Fixed the SHA1 implementation to work on various platforms.
3962 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3964 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3965 API. It is part of the scheduler now. Everything else is
3966 as previously but some functions has changed their names.
3967 Checkout the lib/silcutil/silcschedule.h for the interface.
3968 Updated all applications to use the new interface. Affected
3969 files are lib/silcutil/silcschedule.[ch].
3971 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Found a bug in the SKE implementation. The HASH value,
3974 specified by the protocol, was not computed correctly. The
3975 public key of the responder was not added to the computation
3976 even though it is mandatory. Affected file lib/silcske/silcske.c.
3977 This unfortunately causes incompatibilities with older
3978 clients and servers.
3980 * Added WIN32 specific network init and uninit functions:
3981 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3982 the Winsock2. Affected file lib/silcutil/silcnet.h and
3983 lib/silcutil/win32/silcwin32net.c.
3985 * Set the socket always to nonblocking mode on WIN32 after
3986 reading data or writing data. Affected file is
3987 lib/silcutil/win32/silcwin32sockconn.c.
3989 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Fixed various compilation problems under WIN32. Affected
3992 files lib/silcutil/win32/silcwin32thread.c and
3993 lib/silcutil/win32/silcwin32schedule.c.
3995 * Removed all _internal.h #includes from public header
3996 files. Internal headers must never be included from
3999 Removed also the lib/silcske/payload_internal.h file.
4001 * All include files that may be needed (public and some others
4002 included by the public headers) by application developers are
4003 now copied to the ./includes directory. It does not copy any
4004 internal headers. Affected file Makefile.defines.pre and all
4005 Makefile.am's under lib/ and subdirs.
4007 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4009 * Do not change the ~/.silc directory's permissions automatically.
4010 Affected file irssi/src/silc/core/clientutil.c.
4012 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Do not cancel the protocol in silc_server_close_connection
4015 it might cause recursion. Now cancelled in the function
4016 silc_server_free_sock_user_data. Affected file silcd/server.c.
4018 * Fixed the silc_server_remove_clients_by_server to regenerate
4019 the channel keys correctly finally. Added also new function
4020 silc_server_remove_clients_channels to actually do it.
4021 Affected file silcd/server.c.
4023 * Fixed the silc_server_new_channel to not crash by giving
4024 wrong router to the new channel. Affected file is
4025 silcd/packet_receive.c.
4027 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4030 which is given as argument to the silc_client_alloc now.
4031 It can be used to configure the client and set various parameters
4032 that affect the function of the client.
4034 * The USERS command in server did not check whether the channel
4035 is private or secret. Affected file silcd/command.c.
4037 * Added new argument to the USERS command in protocol specification.
4038 The USERS command now can take the channel name as argument
4039 as well. Added support for this in client and server and
4040 updated the protocol specs.
4042 * Completed the GETKEY command in client. It can be now used
4043 to fetch also servers public key not only some clients.
4044 Affected files lib/silcclient/command[_reply].c.
4046 * Added silc_client_get_server to return server entry by the
4047 server name. Affected files lib/silcclient/silcapi.h and
4050 * Redefined the IDENTIFY command in protocol specification to be
4051 more generic. It now can be used to query information about
4052 any entity in the SILC Network, including clients, servers and
4053 channels. The query may be based either the entity's name
4054 or the ID. Added support for this in both client and server.
4056 Affected files silcd/command.c and lib/silcclient/command.c
4057 and command_reply.c.
4059 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4060 the _from_client and _from_server functions. Affected file
4063 * Added silc_client_get_channel_by_id_resolve to the file
4064 lib/silcclient/silcapi.h to resolve channel information by
4065 its ID. Added also silc_client_get_channel_by_id that
4066 does not resolve it from the server.
4068 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Added SilcServerEntry context into the client library
4071 to represent one server. The INFO command now allocates
4072 these to save the resolved server info. For now on the
4073 client library will also keep information about servers,
4074 connected and resolved with INFO.
4076 The INFO command now allocates the SilcServerEntry context
4077 and saves the server info there. The COMMAND_REPLY in
4078 the INFO now returns the parameters to application in
4079 same order as defined in the protocol specification.
4081 The entries are cached in the client->server_cache.
4083 * The INFO command is now issued after received the Client ID
4084 from the server. Affected file lib/silcclient/client.c.
4086 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4087 to the application as the mode changer might be server.
4088 It is guaranteed that NULL is not returned anymore to the
4089 application. Affected file lib/silcclient/client_notify.c.
4091 The ID Type is now also passed to the application so that
4092 it can check whether the returned entry is SilcClientEntry
4095 Added new function silc_client_get_server_by_id to return
4096 the server entry by ID. Affected files are the
4097 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4099 * Do not create the channel in the Irssi SILC Client when issuing
4100 the JOIN command but when received the sucessful JOIN command
4101 reply. Otherwise the channel might get created even though we
4102 could not join it. The Affected file is
4103 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4105 * Fixed a channel joining bug in router. The router must also
4106 check the channel modes, invite and ban lists etc. when serving
4107 the JOIN command sent by normal server. Affected file is
4108 silcd/command.c. The router now resolves the client's
4109 information from the server who sent the JOIN command if it
4110 does not know it, and processes the JOIN command only after
4113 * Changed the SilcCommandCb to take new argument; void *context2.
4114 Affected file lib/silccore/silccommand.h
4116 The second argument in the command callbacks in the server now
4117 includes the SilcServerCommandReplyContext if the command was
4118 called as pending command callback from the command reply.
4119 Otherwise it is NULL. When called as pending the status of the
4120 command reply will be checked and if it was erronous the
4121 error will be sent to the original sender of the command.
4122 This way the client always receives the error messages even
4123 though the server was actually the one who received the error
4124 when it resent the command to router, for example. Affected
4125 files silcd/command[_reply].[ch].
4127 * Fixed sending WHOWAS command's error message to client if
4128 the requested client could not be found. It was missing.
4131 * Changed the CMODE and CUMODE commands reply arguments in the
4132 protocol specification. The Channel ID is now sent in both
4133 of the commands to identify the channel. Implemented this
4134 new feature to the client and server. Affected files
4135 lib/silcclient/command_reply.c and silcd/command.c.
4137 * Made better checks for invite and ban lists in the JOIN
4138 command in server. Affected file silcd/command.c.
4140 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4142 * The server now performs the incoming host IP/DNS lookup
4143 using the silc_socket_host_lookup and thus does not block
4144 the server anymore. Affected file silcd/server.c.
4146 * Completed the multi-thread support for SILC Scheduler in
4147 the lib/silcutil/silcschedule.c.
4149 * Fixed the configure.in.pre to detect the pthread correctly
4152 * Fixed a deadlock in silc_task_queue_wakeup in the file
4153 lib/silcutil/silctask.c.
4155 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4157 * Added new function silc_schedule_wakeup that is used in
4158 multi-threaded environment to wakeup the main thread's
4159 schduler. It needs to be used when a thread adds a new task
4160 or removes a task from task queues. After waking up, the
4161 scheduler will detect the task queue changes. If threads
4162 support is not compiled in this function has no effect.
4163 Implemented the wakeup mechanism to both Unix and WIN32
4164 systems. Affected files are lib/silcutil/silcschedule.[ch],
4165 lib/silcutil/unix/silcunixschedule.c and the
4166 lib/silcutil/win32/silcwin32schedule.c.
4168 * Added new function silc_task_queue_wakeup to wakeup the
4169 scheduler by the specified task queue. Affected file
4170 lib/silcutil/silctask.[ch].
4172 * The silc_socket_host_lookup_start now wakes up the scheduler
4173 after adding the timeout task. Affected file is
4174 lib/silcutil/silcsockconn.c.
4176 * The silc_socket_host_lookup is synchronous now if the threads
4177 support is not compiled in. However, the callback is still
4178 called asyncronously through the scheduler, anyway. Affected
4179 file lib/silcutil/silcsockconn.c.
4181 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4183 * Added new function silc_socket_host_lookup to perform
4184 asynchronous IP and FQDN lookups for the socket connection.
4185 Affected files lib/silcutil/silcsockconn.[ch].
4187 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4190 that may or may not compile the mutex support in.
4192 Changed the silc_mutex_alloc interface. It allocates the
4193 mutex now to the sent pointer and returns TRUE or FALSE.
4195 Affected file lib/silcutil/silcmutex.h.
4197 * Wrote the SILC Task Queue interface to support multi-threads.
4198 Affected file lib/silcutil/silctask.[ch].
4200 * Wrote the SILC Scheduler to support multi-threads. Affected
4201 file lib/silcutil/silcschedule.c.
4203 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4206 in lib/silcutil/win32/.
4208 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4210 * Defined SILC Mutex API and SILC Thread API and implemented
4211 them for Unix. Affected files are
4212 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4213 lib/silcutil/unix/silcunixmutex.c and
4214 lib/silcutil/unix/silcunixthread.c.
4216 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Fixed the silc_server_remove_clients_by_server's channel
4219 key re-generation. The hash table handling was incorrect
4220 and would not work with many channels. Affected file is
4223 * Fixed some memory leaks around the server code.
4225 * Rewrote the silc_server_get_users_on_channel to support IPv6
4226 based Client ID's. Affected file silcd/server.c.
4228 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4229 specification. However, a separate document must be written
4230 to define the detailed signing procedure and the payload
4231 associated with the flag. Defined the flag to the
4232 lib/silccore/silcchannel.h as well.
4234 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4236 * Changed the dynamic tables to static size tables in the
4237 lib/silccrypt/silchmac.c.
4239 * Removed GCC dependencies from the code. A patch by cras.
4241 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4243 * Do not show the error "Error receiving packet bla bla"
4244 in server if it really was not an error (-2 means that reading
4245 is pending). Affected file silcd/server.c.
4247 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4249 * Fixed a possible crash in silc_server_remove_clients_by_server
4250 in silcd/server.c. Fixed there also some memory leaks.
4252 * Fixed the silc_idlist_replace_client_id. It could replace
4253 wrong key in the hash table. Affected file silcd/idlist.c.
4255 * Do not check whether there are global users on the channel
4256 if the channel->global_users is FALSE. Affected functions
4257 silc_server_remove_from_one_channel and
4258 silc_server_remove_from_channels in silcd/server.c. Also,
4259 do not check if the removed client is local as we can be
4260 sure that global client was not removed from the channel
4261 and checking for global users is not needed.
4263 * The silc_server_remove_clients_by_server now re-generates
4264 the channel keys correctly for those channels that had
4265 clients removed from them. Affected file silcd/server.c.
4267 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4269 * Found the reason of random crashes in the server. We weren't
4270 ignoring the SIGPIPE signal (which can be sent in write())
4271 and it crashed the server. Affected file silcd/silcd.c.
4273 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4275 * Assure that sock->user_data is not NULL in the function
4276 silc_server_packet_send in silcd/packet_send.c.
4278 * Disconnect the remote connection if it could not be added
4279 to any ID lists in the server. The affected file is
4282 * Check in silc_server_packet_send[_real/dest] that the
4283 socket is not disconnecting and ignore the data if it is.
4284 Affected file silcd/packet_send.c.
4286 * Define inline to __inline on native WIN32 compilation.
4287 Affected file includes/silcwin32.h.
4289 * Added some explicit type casts for inline code since MSVC
4290 require them. Affected files lib/silcutil/silcbuffer.h,
4291 lib/trq/silcdlist.h and lib/trq/silclist.h.
4293 * Print warning in log files from now on if the packet
4294 decryption fails. Affected file silcd/server.c.
4296 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4298 * Changed the `say' client operation's interface to accept
4299 new `type' argument to indicate the type of the message sent
4300 by the library. The application may filter the library's
4301 messages according the type. The affected file is the
4302 lib/silcclient/silcapi.h.
4304 * Added two new functions to lib/silcclient/silcapi.h:
4305 silc_client_del_client and silc_client_del_client_by_id.
4306 Affected file lib/silcclient/idlist.c.
4308 * Moved the clientincludes.h from includes/ to silc/ and
4309 serverincludes.h from includes/ to silcd/.
4311 * The modes for the CMODE and CUMODE are now passed as
4312 uint32 for application with COMMAND_REPLY. The affected
4313 file is lib/silcclient/command_reply.c.
4315 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4317 * /WHOIS without arguments shows client's own information.
4318 Affected file lib/silcclient/command.c.
4320 * Changed PING to not accept any arguments. The specs
4321 says that client can ping only the connected server so
4322 requiring an argument is not needed. Affected file is
4323 lib/silcclient/command.c.
4325 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4327 * Fixed a fatal bug in private message sending and reception
4328 encryption and decryption when using private message keys.
4329 The implementation was incorrect and did not follow the
4330 specification. It causd that some of the message were
4331 lost since it did not use the sending and receiving keys
4332 as the protocol suggests. This has been fixed and will cause
4333 incompatibilities with older clients when sending private
4334 message encrypted with private message keys. Affected files
4335 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4336 and various other in Irssi SILC Client.
4338 Added `responder' boolean argument to the functions
4339 silc_client_add_private_message_key[_ske] to indicate when
4340 the key is added as responder or initiator of the key
4343 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4345 * Removed the silc_ske_check_version function and created
4346 a SilcSKECheckVersion callback. Added also a function
4347 silc_ske_set_callbacks that is now used to set all SKE
4348 callbacks. The callback functions are not given to
4349 the SKE functions anymore, but this function is used to
4352 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4354 * Added `silc_version' argument to the silc_client_alloc
4355 to define the version of the application for the library.
4356 The library will use the version string to compare it
4357 against the remote host's (usually a server) version
4358 string. Affected file lib/silcclient/silcapi.h
4360 * Added the KE protocol context to Key Agreement context
4361 in client library so that we can abort the SKE if it
4362 is in process when we get timeout. Affected file is
4363 lib/silcclient/client_keyagr.c.
4365 * Do not resolve the client ID forever if it returns in the
4366 first time that such client does not exist. This was done
4367 for example with private message. Affected file is
4368 lib/silcclient/client_prvmsg.c.
4370 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * Do not add regex.h for WIN32. The affected file
4373 includes/silcincludes.h.
4375 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4376 not work yet 100%. It generates the DLL's automatically
4377 when compiling with --with-win32 under cygwin.
4379 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4381 * lib/contrib/regex.c is not compiled on WIN32.
4383 * Added silc_net_get_socket_opt function to the
4384 lib/silcutil/silcnet.h.
4386 * Added includes/silcwin32.h for WIN32 specific includes
4389 * Do not use ptime structure or any of the posix process
4390 functions on WIN32 in lib/silccrypt/silrng.c.
4392 * Added silc_gettimeofday to provide generic function
4393 for struct timeval on all platforms. Added the function
4394 to lib/silcutil/silcutil.h.
4396 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4398 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4399 library as they clearly belong there. As a plus side we
4400 can make the actual socket connection routines platform
4403 Added also new generic function silc_socket_read and
4404 silc_socket_write (that used to be silc_packet_[read/write].
4405 The implementation of these are platform specific.
4407 * Added WIN32 specific routines of silc_socket_[read/write]
4408 to lib/silcutil/win32/silcwin32sockconn.c.
4410 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4412 * Added preliminary support for native WIN32 compilation under
4413 cygwin (using the -mno-cygwin option for GCC) to the
4414 ./configure.in.pre. The --with-win32 now prepares the
4415 compilation for native WIN32.
4417 * Rewrote the SILC Scheduler interface in the file
4418 lib/silcutil/silcschedule.h. The scheduler is now context
4419 based and does not have anymore any global static scheduler.
4420 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4421 and created lib/silcutil/win32 directory for WIN32 based
4424 * Added Unix specific network routines to the
4425 lib/silcutil/unix/silcunixnet.c and the old
4426 lib/silcutil/silcnet.c includes now only generic routines.
4428 Added WIN32 specific network routines to the
4429 lib/silcutil/win32/silcwin32net.c.
4431 * Added Unix specific utility functions from the
4432 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4434 * Added WIN32 SILC Scheduler to the file
4435 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4438 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4440 * Do not handle JOIN notify in the server if the target client
4441 is not registered (idata->registered == FALSE). The affected
4442 file is silcd/packet_receive.c.
4444 * Update the nickrec->founder in event_cumode in the Irssi SILC
4445 client. Affected file irssi/src/silc/core/silc-channels.c.
4447 * Fixed the CUMODE_CHANGE notify handling in the server when
4448 server and router are announcing their clients on channels.
4449 Now the mode changes are saved and notified correctly. The
4450 affected file is /silcd/packet_receive.c.
4452 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4453 They really did not replace the cache entry in the ID Cache.
4454 Now they do that. Affected file silcd/idlist.c.
4456 * Fixed the KICK notify handling in the Irssi SILC client to
4457 update the channel records so that the kicked client does not
4458 appear to be on the channel. The affected file is
4459 irssi/src/silc/core/silc-channels.c.
4461 * Always update the conn->current_channel when executing command
4462 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4464 * Fixed the KILL notify handling in Irssi SILC client to remove
4465 the killed client on all channels.
4467 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Fixed the silc_parse_command_line to remove extra spaces
4470 from the start and end of the arguments. Affected file is
4471 lib/silcutil/silcutil.c.
4473 * Cancel and free any active protocol in the function
4474 silc_server_close_connection. Affected file silcd/server.c.
4476 * Cancel and free any active protocol in the function
4477 silc_client_close_connction. Affected file is
4478 lib/silcclient/client.c.
4480 * Do not execute the KILL command for clients that are in
4481 history (ie. they are not in the network). Affected file is
4484 * Fixed KILL notify handling, client does not crash anymore.
4485 Affected file irssi/src/silc/core/silc-channels.c.
4487 * Reduced the default packet buffer size from 2048 to 1024 in
4488 lib/silccore/silcpacket.c.
4490 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4491 counter to the SKE context that is incresed when the SKE library
4492 performs async operation outside the library. If the outside
4493 process frees the SKE context and FREED status will be set
4494 and the library will detect after the sync operation that the
4495 libary is freed. The affected files are
4496 lib/silcske/silcske[_status].[ch].
4498 * Resolve the client entry information in the function
4499 silc_client_channel_message to assure that NULL pointer is not
4500 passed as client entry to the application. */
4502 * Fixed the task timeout calculation to assure that there is
4503 never negative timeouts. The affected file is
4504 lib/silcutil/silcschedule.c.
4506 * Fixed the channel user mode notification sending in server.
4507 It was sent point-to-point to the router (or to server by router)
4508 but it needs to be destined to a channel. The routines now
4509 supports sending the channel user mode notifys to the channels
4510 when announcing clients and channels. Affected files are
4511 silcd/server.c and silcd/packet_receive.c.
4513 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4514 It did not actually replace the old channel entry in the cache.
4515 Affected file lib/silcclient/client_notify.c.
4517 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Fixed a possible crash in silc_packet_send_prepare. It now
4520 assures always that there is enough space in the buffer and
4521 at the tail area of the buffer (for MAC).
4523 Fixed the inbound buffer reallocation in silc_packet_read.
4524 It was old code and did not handle the reallocation correctly.
4527 The affected file is lib/silccore/silcpacket.c.
4529 * Fixed buffer overflow in silc_parse_nickname in the file
4530 lib/silcutil/silcutil.c.
4532 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * make install generates new server keys only if there is not
4537 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4540 Added check that if the NOREPLY is set then we will not send
4541 the away message. This avoids infinite loop of away messages
4542 if both clients are away. The affected file is
4543 lib/silcclient/client_prvmsg.c.
4545 * Fixed client crash if /NICK was given without arguments.
4546 Affected file lib/silcclient/command.c.
4548 * Server does not send the invite list in INVITE command back
4549 to the client if the list was not altered. Added this notion
4550 to the protocol spec as well. Affected file silcd/command.c.
4552 Fixed possible crash in INVITE command by checking the
4553 value of silc_server_get_client_route command.
4555 * Fixed the INVITE notify type handling. The arguments are now
4556 taken in correct order and client does not crash. The affected
4557 file is irssi/src/silc/core/silc-channels.c.
4559 Removed the "Inviting xxx to channel" message from the
4560 client library away and let the application handle it.
4561 Affected file lib/silcclient/command.c. Added that message
4562 to Irssi SILC client's message formats.
4564 * Fixed CMODE command crash in client. It now checks the
4565 amount of arguments correctly and does not crash. The affected
4566 file is lib/silcclient/command.c.
4568 * Do not create new channel automatically in silc_channels_join
4569 but check whether the channel by that name already exists.
4570 Affected file irssi/silc/core/silc-channels.c.
4572 * Do not send the SERVER_SIGNOFF to router if the disconnected
4573 entity was the router. Affected file silcd/server.c.
4575 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4576 SILC client as it was missing from there.
4578 Added the handling of the KICK notify to the Irssi SILC client
4579 as it was missing. Added "you have been kicked" message to
4580 Irssi SILC client's message modules formats.
4582 Added the handing of the KILL notify to the Irssi SILC client
4583 as it was missing. Added the kill message module formats
4586 The affected file is irssi/src/silc/core/silc-channels.c.
4588 * The router did not save the channel mode the server announced.
4589 Affected file silcd/packet_receive.c.
4591 * Fixed a possible crash in INFO command in server. If the
4592 server did not provide the server info it crashed. Affected
4593 file silcd/command.c.
4595 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Fixed the GETKEY command in the server to check also the
4598 global list. Otherwise the GETKEY would not work correctly
4599 in normal SILC server. Affected file silcd/command.c.
4601 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Fixed GETKEY crash, it crashed if the command did not succseed.
4605 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4608 is now real and not just an macro interface to GMP.
4610 Removed the entire GMP from the source tree and imported new
4611 NSS MPI library instead. Reason for removing GMP is that it is
4612 extremely large and compiles extremely slow. The NSS MPI
4613 is only a few files and compiles in less than 10 seconds.
4614 The speed is also about the same as GMP. The MPI is imported
4615 to lib/silcmath/mpi.
4617 If the system has GMP installed we will still use the GMP.
4618 If it is not then the NSS MPI will be compiled.
4620 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Merged a long nickname (127 characters long) crash bugfix from
4623 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4625 * Merged a freed memory reference bugfix from Irssi CVS tree.
4626 Affected file irssi/src/core/commands.c.
4628 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Added the server's public key sving and verification to the
4631 server when performing the SKE. This was missing and the
4632 remote server's (or router's) public key was accepted without
4633 checking whether we have it previously or trust it at all.
4634 Affected file silcd/protocol.c.
4636 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Check in the silc_server_timeout_remote if protocol is active
4639 and make sure that the protocol's final callback is called so
4640 that all memory if freed. Affected file silcd/server.c.
4642 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * silc_server_whois_send_reply crashed the server if the nickname
4645 was 127 characters long. Affected file silcd/command.c.
4647 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added sanity check to the silc_server_new_client. If the hostname
4650 is provided inside username then check that the provided hostname
4651 really is the same as the resolved one. If the hostname was not
4652 resolved then check it from the public key. Affected file is
4653 silcd/packet_receive.c.
4655 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4656 if the server disconnected us and the connection is not valid
4657 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4659 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4660 the library to the lib/silcutil/silcutil.[ch].
4662 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Close log file after open. Affected file
4665 lib/silcutil/silclog.c.
4667 * Check whether sock == NULL in silc_client_send_packet and return
4668 if it is. Affected file lib/silcclient/silcclient.c.
4670 * Check rec->entry == NULL in the Irssi SILC Client before
4671 sending the channel message. Affecte file is
4672 irssi/src/silc/core/silc-servers.c.
4674 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Merged a splitted window bugfix from Irssi CVS tree. The
4677 affected file is irssi/src/fe-text/textbuffer-view.c.
4679 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4680 It did not print nickname.
4682 * Improved the distributions system a bit.
4684 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4687 irssi/src/fe-text/gui-window.c.
4689 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4690 to in-active server. The affected file is
4691 irssi/src/silc/core/client_ops.c.
4693 * Resolve the client in USERS command reply if the entry does
4694 not have username resolved. The affected file is
4695 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4696 command to WHOIS command to really resolve stuff. The USERS
4697 is not used any more in any critical section so WHOIS can
4698 be used even though it might be slower than IDENTIFY.
4700 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4703 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Changed the protocol API a bit more consistent in the
4706 lib/silccore/silcprotocol.[ch].
4708 * Changed the following headers to ROBODoc format:
4710 lib/silccore/silcpayload.h
4711 lib/silccore/silcprotocol.h
4712 lib/silccore/silcsockconn.h
4714 All core library headers are now formatted.
4716 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Fixed a bug in Irssi SILC client; do not show that you are
4719 server/router operator if you really are not. Affected file is
4720 irssi/src/silc/core/client_ops.c.
4722 * Renamed silc_command_free_payload to silc_command_payload_free.
4723 Affected file lib/silccore/silccommand.h
4725 * Added silcmath.h to include the prototoypes of various routines
4726 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4729 * Changed the following headers to ROBODoc format:
4731 lib/silccore/silcchannel.h
4732 lib/silccore/silccommand.h
4733 lib/silccore/silcid.h
4734 lib/silccore/silcidcache.h
4735 lib/silccore/silcmode.h
4736 lib/silccore/silcnotify.h
4737 lib/silccore/silcpacket.h
4738 lib/silcmath/silcmath.h
4740 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Added checking to the server code not to start the server if
4743 ciphers and stuff are not configured properly. Affected files
4744 silcd/serverconfig.[h] and silcd/server.c.
4746 * Changed the layout of the header files of the public interfaces
4747 in the SILC libraries. The new layout supports ROBODoc
4748 documentation tool (and some others) so that it is easy to create
4749 a library reference manual. All the other headers and source
4750 code must still follow the CodingStyle document. Also source
4751 code must not include these ROBODoc stuffs, only the headers.
4752 Furthermore, all public interface headers must now be named
4753 by using `silc' prefix, example: silcapi.h, silccipher.h.
4754 Some files were renamed due to this. All the other headers
4755 must not be used as public interfaces. I will update the
4756 CodingStyle document later. Changed following headers, so far:
4758 lib/silcclient/silcapi.h
4759 lib/silccore/silcauth.h
4760 lib/silccore/silcprivate.h
4761 lib/silccrypt/silcdh.h
4763 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Removed silc_client_packet_send_flush from the client library
4768 as it is not needed. Affected file lib/silcclient/client.[ch].
4770 * Added printing of message of unresolved authentication method
4771 to the Irssi SILC client. Added it to the module formats.
4772 Removed the same message from the client library.
4774 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added new distribution feature, DISTLABEL. Every distribution
4777 can define own preprocessor label that can be used in the
4778 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4779 file distributions, acconfig.h.pre and prepare.
4781 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4783 * Added Makefile.defines_int to include the actual definitions
4784 for Makefile.defines.in. Tested the new distribution system,
4785 created distributions and tested installation.
4787 * Added AWAY message printing to the Irssi SILC client. Added
4788 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4790 * Added SCONNECT command to call the SILC's CONNECT command.
4791 Cannot use CONNECT directly since Irssi uses that internally.
4792 Affected file irssi/src/silc/core/silc-servers.c.
4794 Added ACTION local command. It is same as ME command but takes
4795 the channel as mandatory argument.
4797 Rewrote some of the Irssi's help files to suite for SILC
4800 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Added Makefile.defines[.in] that should for now on be included
4803 in all Makefile.am file in the source tree. That file includes
4804 all common compilation definitions for SILC source tree.
4806 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Minor changes to the ./prepare script to change the package
4809 name according the distribution name to the configure.in.
4811 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Created new distribution system. Added file `distributions'
4814 that defines all the distributions that can be created out of
4815 the SILC source tree. The ./prepare script now reads that
4816 file to determine how to prepare the distributions. The
4817 first argument to the ./prepare is the name of the distribution
4818 and second is the version of the distribution. If given
4819 without arguments it creates the default (toolkit) distribution
4820 with the default version (defined in ./prepare).
4822 All Makefile.am files that are subject to the distributions
4823 are now named as Makefile.am.pre. These are ./Makefile.am
4824 and lib/Makefile.am. Others may be changed later.
4826 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added invite list, ban list, some key management and connection
4829 error message printing to module formats in the Irssi SILC client.
4831 * Added new silc_client_set_away_message to set the away message
4832 that is back to the person who sent private message. The
4833 affected file lib/silcclient/silcapi.h and the
4834 lib/silcclient/client_prvmsg.c.
4836 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Fixed the private message sending in the Irssi SILC client,
4839 added local command KEY to the Irssi SILC client.
4841 Added key management and key agreement message formats to the
4842 irssi/src/fe-common/silc/module-formats.[ch].
4844 Added USERS (alias WHO) printing, server/router operator
4845 indication and LIST command printing to the module formats.
4847 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Fixed channel joining notify handling, cumode notify handling
4850 from Irssi SILC client.
4852 * Added SILC specific module-formats to the Irssi SILC client so
4853 that SILC specific message hilighting, colors etc is possible.
4854 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4856 Added channel mode, channel user mode, actions, notices,
4857 whois and whowas printing to the the module-formats.c.
4859 * Fixed a bug in channel deletion in the server. The channel
4860 is not left to the cache even if the channel founder auth mode
4861 is set when there are no users anymore on the channel. Affected
4862 file silcd/server.c.
4864 * The silc_net_localhost now resolves the entire hostname including
4865 the domain name. Affected file lib/silcutil/silcnet.c.
4867 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Changed the ask_passphrase client operation to be ascynchronous.
4870 It has now a completion callback and a context that the
4871 application must call after it has got the passphrase from
4872 the user. Affected files lib/silcclient/silcapi.h,
4873 lib/silcclient/protocol.c, lib/silcclient/command.c and
4876 Added SilcAskPassphrase callback that the application calls
4877 to deliver the passphrase to the library.
4879 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4880 The public key verification and especially a certificate
4881 verification is asynchronous procedure.
4883 Added new SILC_SKE_STATUS_PENDING status to indicate the
4884 request is pending and a callback will be called to finalize
4887 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4888 indicate that remote end did not send its public key (or
4889 certificate), even though we require it. Added check for this
4890 condition in the SKE. This was a security bug, now fixed.
4892 Defined new SilcSKEVerifyCbCompletion callback that is called
4893 when the verification process is completed.
4895 The affected files lib/silcske/silcske_status.h and
4896 lib/silcske/silcske.[ch].
4898 * Changed the verify_public_key client operation to be async
4899 as well. Defined SilcVerifyPublicKey callback that is used to
4900 indicate the success of the public key verification process.
4902 Changed the server and client to use the new async client
4905 * Changed the Irssi SILC client's internal scheduler to be called
4906 twice as many times as it used to be. As a result the client
4907 should be a bit faster now. Affected file is
4908 irssi/src/silc/core/silc-core.c.
4910 * Added support to Irssi SILC client of asynchronous public key
4911 verification and passphrase inquiry. Affected file is
4912 irssi/src/silc/core/silc-core.c.
4914 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Do not say "You have left channel %s" in client library.
4917 Moved it to the application. Affected files are
4918 lib/silcclient/command.c and silc/client_ops.c.
4920 * Fixed silc_client_get_clients. Command context was not
4921 duplicated and was freed memory in the callback. Affected
4922 file lib/silcclient/idlist.c.
4924 * Do not say "you are now talking..." on JOIN command in the
4925 client library. The appliation must handle it.
4927 * Do not say ".. changed topic to" in command reply in the
4928 client libary. The application must handle it.
4930 * Fixed TOPIC command sending in the client library.
4932 * Fixed a memory leak in silc_client_command_free in the file
4933 lib/silcclient/command.c.
4935 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Imported a modified version of Irssi client to the source tree.
4938 The Irssi will be used to create a new client called
4939 Irssi SILC. Imported to irssi/.
4941 Added silc_core_init_finish function to the Irssi. Affected
4942 file irssi/configure.in.
4944 A lot changes in the Makefile.ams around the irssi tree.
4946 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Do not rehash if the new size is same as the old size of the
4949 hash table, in the silc_hash_table_rehash*. The affected file
4950 lib/silcutil/silchashtable.c.
4952 * Replaced hash_table_del_by_context calls from the server
4953 (when channel->user_list and client->channels) to the
4954 hash_table_del as it is sufficient and faster.
4956 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Added silc_hash_table_list, silc_hash_table_get and the
4959 SilcHashTableList structure to provide an alternative way to
4960 traverse the hash table. The affected files are
4961 lib/silcutil/silchashtable.[ch].
4963 * Changed the server's idlist routines to use the hash table
4964 routines to optimize the code.
4966 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Replaced the client entry's `channel' list and channel entry's
4969 `user_list' list to hash tables for optimized lookup. Changed
4970 the code to use the hash table interface around the code.
4971 Affected file lib/silcd/idlist.[ch].
4973 * Added `auto_rehash' boolean argument to the function
4974 silc_hash_table_alloc to indicate whether the hash table should
4975 auto-rehash when it thinks is appropriate time. It will
4976 increase the hash table size if the there is twice as much
4977 entries in the table than the size of the table, and will
4978 decrease the size if there are twice as less entries than
4979 the size of the table.
4981 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4985 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * silc_idcache_purge_by_context deletes the entry now by context
4988 as it is supposed to do. Affected file lib/silccore/idcache.c.
4990 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4991 client is not anymore valid (WHOWAS givens the info) and not
4992 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4994 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Removed the `data' and `data_len' arguments from the ID Cache
4997 interfaces and added `name' argument. ID Cache does not handle
4998 anymore the binary data only a names associated with given ID.
5000 * When hashing a Client ID with silc_hash_id the entire ID is
5001 not hashed anymore, instead only the hash of the Client ID is
5002 hashed. This way we can access the Client ID from the cache
5003 with Client ID but with the hash of the ID (which is a hash of
5004 the nickname) as well without any difference in performance.
5006 Added also silc_idcache_find_by_id_one_ext to do one on one
5007 searching when we have the actual ID. Added also function
5008 silc_hash_client_id_compare. The affected files are
5009 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5011 * When hashing the name associated with a ID it is always done
5012 in lowercase. This way we can access the cache without worrying
5013 about case-sensitivity, even though, for example nicknames are
5016 * Fixed a bug in server with channel message sending. It put
5017 wrong ID type as destination ID. The affected file
5018 silcd/packet_send.c.
5020 * silc_idcache_del_by_context now deletes from all hash tables
5021 by context. Affected file lib/silccore/idcache.c.
5023 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Changed the client library to use the new ID Cache interface.
5026 Changes around the source tree.
5028 * Added silc_hash_table_rehash_ext to rehash with specific
5029 hash function. Affected file lib/silcutil/silchashtable.[ch].
5031 * Added silc_hash_string_compare to compare two strings in the
5032 hash table. Affected file lib/silcutil/silcutil.[ch].
5034 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Added new function silc_idcache_del_by_context into the
5037 lib/silccore/idcache.[ch].
5039 * Changed the server's ID list routines to use the new ID Cache
5040 interface. Changes around the source tree.
5042 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Added silc_hash_table_del[_by_context]_ext functions in to the
5045 lib/silcutil/silchashtable.[ch].
5047 Removed silc_hash_table_find_all* routines and added new
5048 silc_hash_table_find_foreach to replace them.
5050 Added silc_hash_table_replace_ext function as extended
5051 replacing function. Separated the simple hash table interface
5052 from the extended hash table interface in the file
5053 lib/silcutil/silchashtable.h.
5055 * Fixed minor bugs and changed it to use some of the new
5056 hash table functions in lib/silccore/idcache.c
5058 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Added new function silc_hash_table_find_all to return all keys
5061 in the hash table by the specified key. As the hash table is
5062 collision resistant it also makes it possible to have several
5063 duplicate keys in the hash table. This function may be used to
5064 find all of the keys from the hash.
5066 Added user_context arguments to the SilcHashFunction,
5067 SilcHashCompare and SilcHashDestructor to deliver user specified
5070 Added new fuctions silc_hash_table_find[_all]_ext to do
5071 extended lookup with specified hash and compare functions and
5072 specified user contexts.
5074 Added new function silc_hash_table_add_ext to add the key
5075 with specified hash function and user context.
5077 Added new function silc_hash_table_foreach to traverse all
5078 entrys in the hash table. Added SilcHashForeach callback
5081 Added new function silc_hash_table_del_by_context to delete
5082 the entry only if the context associated with the key matches.
5084 Affected files are lib/silcutil/silchashtable.[ch].
5086 * Removed silc_hash_[server/client/channel]_id and added just
5087 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5088 silc_hash_id_compare to compare two ID's using as the hash table
5089 comparison function. Added also silc_hash_data to hash
5090 binary data and silc_hash_data_compare to compare it.
5092 * Removed silc_idlist_find_client_by_hash as it is not needed
5093 anymore. Affected file silcd/idlist.[ch].
5095 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5096 to use internally the SilcHashTable. The new ID Cache is a lot
5097 faster than the old one. Some of the ID Cache interface was also
5098 rewritten and obsolete and stupid functions were removed.
5100 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Added entry_count field to the SilcHashTable to keep the number
5103 of the entries in the table. Implemented the function
5104 silc_hash_table_rehash. Added new function
5105 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5107 Fixed a minor bug in silc_hash_table_free.
5109 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5110 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5111 into the lib/silcutil/silcutil.[ch].
5113 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Implemented a collision resistant hash table into the
5116 lib/silcutil/silchashtable[ch]. See the header and the source
5117 for the SilcHashTable API.
5119 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Merged dotconf version 1.0.2 into lib/dotconf.
5123 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Do not compile anything in lib/silcsim/* if the SIM support
5126 is not enabled. The tree should now compile without problems
5129 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Compiled the SILC under cygwin. Compiled and tested briefly
5132 without problems. More tests needed. The SIMs didn't compile
5135 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5137 * Fixed possible crash in silc_get_username in the
5138 lib/silcutil/silcutil.c.
5140 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Fixed a va_arg in silc/client_ops.c.
5144 * Oops, RC5 routines were named AES and caused some problems
5145 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5147 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Added new SilcIDIP structure into the lib/silccore/id.h and
5150 replaced the old `ip' fields from all SILC ID's to that type.
5151 This is a step towards IPv6 support.
5153 The silc_id_get_len takes now the ID as an extra argument.
5154 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5155 both IPv4 and IPv6 based ID's.
5157 The affected files are lib/silccore/id.[ch] and other files
5158 around the tree using these routines.
5160 * Removed the ID length arguments in server from various
5161 silc_server_send_notify_* routines -> they are not needed
5164 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Fixed memory leak in silc_encode_pem_file in the file
5167 lib/silcutil/silcutil.c.
5169 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Check minor version as well in the SKE. Affected files are
5172 silcd/protocol.c and lib/silcclient/protocol.c.
5174 * Added --identifier option to the server so that an identifier
5175 can be when creating the public key for the server. Affected
5176 file is silcd/silcd.c.
5178 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5179 lib/silccrypt/silcpkcs.c.
5181 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Register default ciphers and stuff when using -C option with
5184 the server. Affected file sildc/silcd.c.
5186 * Put back the servers public key filename format, it is better
5187 than the new one. For now, the client keys are saved with the
5188 new filename format. The affected file silc/client_ops.c.
5190 * Implemented the Cipher API for the rest of the ciphers that
5191 did not implement it or implemented it the wrong way.
5193 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Register default ciphers and stuff when using the -S option
5196 in the client. Affected file silc/silc.c. Same also when
5197 creating new key pair with -C option.
5199 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Fixed the silc_verify_public_key client operation function to
5202 save the public keys differently. The fingerprint is now
5203 used as filename and not the hostname. This way also the
5204 client keys are saved uniquely and not with hostnames. The
5205 affected file is silc/client_ops.c.
5207 * Trimmed the silc_hash_fingerprint function to remove extra
5208 whitespaces from the end of the fingerprint. The affected
5209 file is lib/silccrypt/silchash.c.
5213 * Added silc_cipher_register_default function to register all
5214 default ciphers. It can be used when configuration files
5215 does not exist and the application does not want any specific
5216 ciphers in any specific order.
5218 The SilcDList is now used as silc_cipher_list dynamically
5219 allocated cipher list. Removed the static list all together
5220 and now all ciphers must be allocated to the dynamic list.
5221 The silc_cipher_alloc routine was changed to check only the
5224 All silc_cipher_* routines that used to return int returns
5227 The affected files lib/silccrypt/silccrypt.[ch].
5229 * The same thing was done to silc_hash_* as for silc_cipher_*
5230 routines. Affected files lib/silccrypt/silchash.[ch].
5232 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5233 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5234 Added also silc_pkcs_[un]register[_default] functions.
5235 Removed the data_context from the PKCS API.
5237 * Added silc_hmac_register_default function to register default
5238 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5239 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5240 to unregister all hmacs at once.
5242 * Register the default ciphers, hash functions, PKCSs and HMACs
5243 if client's configuration file does not exist. The affected
5246 * The client did not load the hash functions from the SIM
5247 modules at all. Added support for this. Affected file is
5248 silc/clientconfig.c.
5250 * When decoding public key with silc_pkcs_public_key_decode, check
5251 the supported algorithm only if PKCS are registered. Affected
5252 file lib/silccrypt/silcpkcs.c. The same was done with the
5253 silc_pkcs_private_key_decode.
5255 * Fixed the SILC List routines to keep the list always in order.
5256 It used to change the list's order when traversing the list but
5257 not it preserves the order. Affected file lib/trq/silclist.h.
5259 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Added the client library to use the SilcSocketConnection's
5262 reference counter (by silc_socket_dup) to prevent the bug that
5263 the socket object may be freed underneath async operation.
5265 * The name resolv library checking fixes in the configure.in.pre.
5268 * Created new version of the protocol drafts for future
5269 development. The -03 drafts are the ones that will be changed
5270 in the trunk now and the -02 will remain as they are.
5272 * Send list of CUMODE notifys to the router when announcing
5273 the channel users to the router. Affected file silcd/server.c.
5274 If the router receiving channel founder CUMODE for a channel
5275 that already has channel founder it will send CUMODE notify
5276 to the sender to remove the channel founder rights from the
5277 announced client. Affected file silcd/packet_receive.c.
5279 * The CUMODE notify may now use Server ID as well as the entity
5280 who changes the mode. Updated protocool specs.
5282 * Updated INSTALL and README files.
5284 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * New web pages in the http://silc.pspt.fi. The pages was
5291 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Implemented the [DenyConnectin] config section in the server.
5294 Added silc_server_config_denied_conn to check whether incoming
5295 connection is denied. Affected file silcd/serverconfig.[ch].
5297 * Do not check the ports when checking the incoming configuration
5298 data if the port is 0, meaning any. Affected file is
5299 silcd/serverconfig.c.
5301 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed buffer overflow in silc_string_compare in the file
5304 lib/silcutil/silcutil.c.
5306 * Fixed double free in silc_server_command_leave in the file
5309 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Fixed the version checking in the server. Affected file is
5314 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Fixed the configuration data fetching when accepting new
5317 connections in the server. Affected file silcd/server.c.
5319 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Added `sender_entry' argument to the function
5322 silc_server_packet_relay_to_channel so that we can check
5323 whether some destination actually belongs to the same route
5324 the sender belongs (ie, we must not resend the packet to the
5325 sender). Affected file silcd/packet_send.[ch].
5327 * Added `servername' field to the SilcClientEntry in the server
5328 to hold the name of the server where client is from. Affected
5329 file is silcd/idlist.h.
5331 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Moved the channel message encrypting in the router betwen
5334 router connections from silc_server_channel_message to the
5335 silc_server_packet_relay_to_channel since we want to check
5336 whether we have anybody channel before encrypting anything.
5337 Affected files silcd/packet_[receive/send].c.
5339 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Fixed the [AdminConnection] server config section to support
5342 multiple entries. Affected file silcd/serverconfig.c.
5344 * Added support into the server to check the validity of the
5345 incoming connection before executing any KE or authentication
5348 * The connection configuration is now saved to the KE and
5349 connection auth protocol contexts and not fetched anymore in
5350 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5352 * The local hosts listenning address and port is also resolved
5353 now when starting the server. We want to have the socket object
5354 to include the real address and port for the listener. Added
5355 new function silc_net_check_local_by_sock into the files
5356 lib/silcutil/silcnet.[ch].
5358 * Fixed a broadcast bug in server -> do not broadcast if we
5361 * Fixed a routing bug. Do not route broadcast packets ever.
5362 Broadcast packets must be processed always and not routed since
5363 they may be destined to some other host than yourself and thus
5364 would get routed without no good reason. Affected file is
5367 * Added function silc_server_config_is_primary_route to check
5368 whether primary router connection has been configured (a router
5369 configuration that we are initiating). If there is not, we
5370 will assume that there is only two routers in the SILC network
5371 and we will use the incoming router connection as our primary
5372 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5374 * Changed the order of the broadcasting. Broadcast _after_ the
5375 packet has been processed not before. Affected file is
5378 * Fixed a [ClientConnection] parsing bug. The port was never
5379 parsed correctly thus resulting to port 0. Affected file
5380 silcd/serverconfig.c.
5382 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5383 argument and did not set the broadcast packet flag. Affected
5384 file silcd/packet_send.c. Fixed same bug in the function
5385 silc_server_send_notify as well.
5387 * If we receive NEW_ID packet for our own ID in the server, ignore
5390 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Removed the nickname from the Private Message Payload.
5395 Updated the code and the protocol specs.
5397 * Updated protocol specs for submitting to the IETF.
5399 * Tweaked the Random Number Generator a bit. Affected file
5400 lib/silccrypt/silcrng.c. Exported a new function
5401 silc_rng_[global]_add_noise which can be used to add more
5404 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Do not parse packets with different timeout when protocol
5407 is active -> may cause problem with rekey. Affected file
5410 * When server receives signoff notify it must not create
5411 new channel key if the client is on any channels since the
5412 sender of the signoff notify will create it.
5414 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added printing of error messages during SKE protocol from the
5417 failure packet sent by server during SKE. Affected file
5420 * Removed the client's failure_callback handling with timeout
5421 and handle it immediately when received.
5423 * The SKE library returned wrong type in SUCCESS and FAILURE
5424 packets. They must be 32 bit MSB not 16 bit MSB.
5426 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Ok, rewrote the logic of the re-key and now it seems to work.
5429 I tested it on high traffic with frequent re-keys without
5430 problems. Added hmac_receive (and renamed hmac to hmac_send)
5431 in SilcClientConnection in lib/silcclient/client.h and
5432 in SilcIDListData in silcd/idlist.h. Also, removed the
5433 SilcPacketParserContext's cipher and hmac fields as they are
5434 not needed anymore and actually caused some problems when
5435 the ciphers and hmac's changed underneath the packet parser.
5437 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * If re-key protocol is active then process the incoming packets
5440 synchronously since we must assure that icoming packets encrypted
5441 with the old key is processed before the new keys is set to
5442 use. This is true other packets than for REKEY packets.
5443 Affected file silcd/server.c. The same was done to client library
5444 as well, affected file lib/silcclient/client.c.
5446 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed bug in client and server to accept the force send if
5449 the packet is send from silc_[server/client]_packet_process
5450 function. Otherwise the packets are never delivered, oops.
5452 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Disable force sending of packets when REKEY protocol is active.
5455 We must assure that no packet is sent directly when rekey is
5456 performed. All packets must be sent through packet queue.
5457 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5458 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5459 function is silc_[server/client]_packet_send_real to check
5462 * Replaced the SIM paths from example config files to
5463 /usr/local/modules. Also, make install creates now
5464 /usr/local/silc/logs directory to hold all the SILC server
5467 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Made the configure.in.pre work on Solaris. Patch by salo.
5471 * Made all ciphers compatible with non-x86 machines. Defined
5472 CBC mode macros into lib/silccrypt/ciphers_def.h.
5474 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Fixed the make install.
5478 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * When MAC computation fails the silc_packet_decrypt returned 0
5481 even though it was supposed to return -1. Fixed this. The
5482 affected file is lib/silccore/silcpacket.c.
5484 * Do not replace the config files in /etc/silc (in make install)
5485 if they already exist. Affected file ./Makefile.am.
5487 * Do not send re-key packets immediately but through packet queue.
5488 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5490 * Changed silc_net_check_host_by_sock to return FALSE if the
5491 IP/DNS could not be resolved. Though, it returns the IP address
5492 now even if it could not resolve it (but returns also FALSE).
5493 Affected file lib/silcutil/silcnet.[ch].
5495 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added silc_pkcs_decode_identifier to decode the public key's
5498 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5499 Added also silc_pkcs_free_identifier. Added also new context
5500 SilcPublicKeyIdentifier.
5502 * Added -S option to the silc client. It is used to dump the
5503 contents of the specified public key file.
5505 * Changed the PKCS api to return the public key length when
5506 setting the public key.
5508 * Fixed a fatal bug in the public and private key file loading.
5509 Affected file lib/silccrypt/silcpkcs.c.
5511 * Execute the packet parsing for client with zero (0) timeout
5512 if the protocol is active. Affected file silcd/server.c.
5514 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Made the key generation options to the silcd program. Added
5517 -C option, equivalent to client's option.
5519 * Added new [ServerKeys] config section to the server. It
5520 configures the server's public and private key.
5522 * Defined generic Public Key Payload into the protocol
5523 specification to send specific type of public keys and
5526 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5527 public key or certificate.
5529 * Implemented the GETKEY command to the server and to the
5530 client library and on user interface.
5532 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Made preliminary `make install' work.
5536 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added SilcServerRekey context into silcd/idlist.h.
5540 * Added the PFS support as defined in the specification to the
5541 SKE protocol. Affected files lib/silcske/*.c.
5543 * Added `ske_group' field to the SilcServerRekey context to hold
5544 the number of the SKE group that is used with PFS in re-key.
5545 Affected file silcd/idlist.h.
5547 * Added PFS re-key support to the server. Affected file is
5550 * Added silc_protocol_cancel to cancel execution of the next
5551 state of the protocol. Affected file is
5552 lib/silccore/silcprotocol.[ch].
5554 * Added the re-key support with and without PFS to the client
5555 library. Re-key is performed once in an hour, by default.
5557 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5558 Added silc_client_rekey_callback and silc_client_rekey_final.
5559 Affected files are lib/silcclient/protocol.[ch] and
5560 lib/silcclient/client.[ch].
5562 * Removed the `hmac_key' and `hmac_key_len' fields from the
5563 SilcClientConnection structure; not needed. Affected file is
5564 lib/silcclient/client.h.
5568 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Do not ask whether user wants to use the negotiated private key
5571 for private messages, just use it. Affected file is
5572 silc/local_command.c.
5574 * Added `send_enc_key' and `enc_key_len' fields to the
5575 SilcIDListData structure since they are needed in the re-key
5576 phase. Affected file is silcd/idlist.[ch].
5578 * Implemented the simple re-key protocol into the server.
5579 Affected files silcd/server.c and silcd/protocol.[ch]. The
5580 re-key will be performed once in an hour, by default.
5582 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5583 Added silc_server_rekey, silc_server_rekey_callback and
5584 silc_server_rekey_final.
5586 * Removed Tunneled flag from the protocol. Updated the code
5587 and the specifications.
5589 * Adde `pfs' field to the SilcIDListData to indicate whether
5590 the PFS is to be performed in the re-key. Affected file is
5593 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5596 int64 of at least the xintXX size. If void * is less that 4
5597 bytes uint32 * will be used. Defined bool as boolean.
5599 * Changed _ALL_ unsigned long and unsigned int to uint32,
5600 unsgined short to uint16 in the source tree.
5602 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5603 not handle clients that has entry->data.registered == FALSE.
5604 They are not in the network anymore. Affected file is
5607 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Implemented the sending of the SERVER_SIGNOFF notify in the
5610 server. Affected file is silcd/server.c.
5612 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5613 Added also silc_notify_payload_encode_args into the
5614 lib/silccore/silcnotify.[ch].
5616 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5617 Affected file silcd/packet_receive.c.
5619 * Implemented the SERVER_SIGNOFF notify handling in the client
5620 library. Affected file lib/silcclient/client_notify.c. Also,
5621 implemnted the printing of the SERVER_SIGNOFF info to the
5622 application. Affected file silc/client_ops.c.
5624 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5625 if the deleting was successful. Affected file silcd/idlist.[ch].
5627 * Added support for public key authentication in the connection
5628 authentication protocol in the client library. Affected file
5629 lib/silcclient/protocol.c.
5631 * Changed the server's silc_idlist_get_clients_by_* interface
5632 to support already allocated array so that new entries may be
5633 added to pre-allocated array. Affected file silcd/idlist.[ch].
5634 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5635 and command replies.
5637 * All command reply functions in the server now calls the
5638 pending command callback even if error occured. This way the
5639 error will be delivered to the client as well. Affected files
5640 silcd/command.c and silcd/command_reply.c.
5642 * Fixed INFO command to return local server's info if no server
5643 was provided. Affected file lib/silcclient/command.c.
5645 * Removed RESTART command for good. Updated the code and the
5648 * Rewrote parts of the task system. It is a bit simpler now.
5649 Removed unsued task priorities. The affected files are
5650 lib/silcutil/silctask.[ch].
5652 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Moved the USERS printing from the library to the application.
5655 Affected files lib/silcclient/command.c and silc/client_ops.c.
5657 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Added channel key re-key support. The re-key is perfomed
5662 only by the router and is done once in an hour. Added `rekey'
5663 field to the SilcChannelEntry in the server. Affected files
5664 silcd/server.c and silcd/idlist.h.
5666 * Added silc_task_unregister_by_context into the file
5667 lib/silcutil/silctask.[ch].
5669 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added SILC_UMODE_GONE mode to indicate when the client is not
5672 present in the SILC network. Added also support to the local
5673 command AWAY that will set this mode. Added support of showing
5674 "xxx is gone" in WHOIS command. The USERS command shows the
5675 gone status as well.
5677 * Fixed setting server and router operator privileges in the
5678 server's UMODE command. Affected file silcd/command.c.
5680 * Merged the SKE KE1 and KE2 payloads into one payload. The
5681 new KE payload is equivalent to the old KE2 payload.
5683 Cleaned up the SKE Start Payload parsing. It now uses the
5684 simple buffer unformatting to do the parsing. A lot faster
5687 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5688 to the SKE that is used to indicate whether both of the SKE
5689 parties should perform authentication. By default only the
5690 responder performs authentication. By setting this flag also
5691 the initiator must do authentication. By default it is unset
5692 since in normal SKE case, client to server connection, only
5693 the responder should do authentication. When doing SKE between
5694 two clients both should perform authentication. Updated the
5695 code and the protocol specs.
5697 * A little fix to IDENTIFY command in the server. Search the
5698 client first by hash not nickname. Affected file is
5701 * Fixed the silc_client_close_connection to support closing
5702 the client to client connections wihtout deleting too much
5703 data. Affected file lib/silcclient/client.c.
5705 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5706 are received if protocol used to be active but is not anymore
5707 the application would crash due to NULL pointer dereference.
5708 Affected files silcd/server.c and lib/silcclient/client.c.
5710 * Added `hash' field to the SilcClientConnection to include
5711 the hash function negotiated in the SKE protocol.
5713 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5714 to set the channel founder authentication data. A client can
5715 claim the founder rights later by providing the authentication
5716 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5717 This way the channel founder can regain the channel founder
5718 privileges even it is left the channel. This works only on
5719 local server and the client must be connected to the same
5720 server to be able to regain the founder rights. Updated the
5721 protocol specs accordingly.
5723 Added support to the CMODE command in the client to set the
5724 founder auth data. Read the README to see how to set it.
5726 Added support to the CUMODE command to claim the founder
5727 rights. Read the README to see how to do it.
5729 Added support for the founder authentication to the Channel
5730 Entry in the server. Affected file silcd/idlist.h.
5732 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5733 server's CMODE command. Affected file silcd/command.c.
5735 * Added the following new functions into lib/silccore/silcauth.[ch]:
5736 silc_auth_get_method and silc_auth_get_data.
5738 * The server now saves the remote hosts public key to the
5739 SilcIDListData pointer. Affected file silcd/protocol.c.
5741 * The normal server now does not remove the channel entry from
5742 the cache if the founder authentication data is set. It used
5743 to remove it if the founder was the last one on the channel on
5744 the server and left the channel. The auth data is saved and
5745 if the channel is re-joined later the old entry is used with
5746 the old auth data. Affected files silcd/command_reply.c and
5749 * Removed the `pkcs' field from the SilcIDListData structure
5750 in the server; it is not used. Affected file silcd/idlist.h.
5752 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Fixed packet processing on slow links. Partial packets were
5755 never re-processed because the incoming data buffer was cleared
5756 by the application. Application must not directly clear the
5757 sock->inbuf, the packet processing routines handle it. Fixed
5758 this in client library and in server.
5760 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Fixed the WHOIS and IDENTIFY send reply function to really
5763 check whether to send list or just one entry. Affected file
5766 * Cleaned up the LEAVE command's channel key distribution. The
5767 affected file silcd/command.c.
5769 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5770 can enforce the channel mode as well. In that case the ID
5771 includes the ID of the server. The code now enforces the
5772 mode change if the router have different mode than the server.
5774 * The notify client operation with CMODE_CHANGE notify can now
5775 return NULL client_entry pointer if the CMODE was not changed
5776 by client. Application must check for this.
5778 * Added <Server ID> argument to INFO command to support server
5779 info fetching by Server ID.
5781 * Added silc_server_announce_get_channel_users to get assembled
5782 packets of channel users of the specified channel. Affected
5783 file silcd/server.[ch].
5785 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5786 was freed underneath the ID Cache.
5788 * Re-announce clients when the server received CHANNEL_CHANGE
5789 notify from the router. Affected file silcd/packet_send.c.
5791 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5794 crashed since it did not handle the fact that there is no cipher
5795 called "3" and didn't check the error condition. Now fixed.
5797 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5798 flag. It can be used to send message requests.
5800 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Implemented the RESTART command in the client.
5804 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5805 notice type messages. Added notice printing to the user
5808 * The channel keys are not re-generated if the channel's mode
5809 is PRIVKEY, ie private key on the channel exists. Affected
5810 files silcd/server.c and silcd/command.c.
5812 * Fixed a little bug in channel message delivery when channel
5813 private keys are set in the server. Affected file is
5814 silcd/packet_send.c.
5816 * Changed the setting on channel->on_channel = TRUE from the
5817 silc_client_save_channel_key to the JOIN command reply. The
5818 key payload is not received if the private channel key is set.
5819 Affected file lib/silcclient/command_reply.c and the
5820 lib/silcclient/client_channel.c.
5822 * When the CMODE_CHANGE notify is sent and the channel private
5823 key mode is removed the channel key must be re-generated in
5824 other cells as well. Added this support for the router in the
5825 silcd/packet_receive.c.
5827 * Added new local command NOTICE to send notice message on
5828 channel. Affected file silc/local_command.[ch].
5830 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added new local command ME to the client. It is used to send
5833 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5834 some action. Affected file silc/local_command.[ch].
5836 * Changed channel_message and private_message client operations
5837 to deliver the message flags to the application. Added also
5838 the `flags' arguments to the silc_client_send_channel_message
5839 and silc_client_send_private_message functions. Affected file
5842 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Redefined the Private Message Payload to support private message
5845 keys and to support the new private message flags. Updated
5846 the protocol specs. Flags makes it possible to have for example
5847 CTCP style messages.
5849 * Added new type SilcPrivateMessagePayload and defined an API
5850 for it in the lib/silcclient/silcprivate.[ch].
5852 * Tested private message private keys successfully. Tested the
5853 private message key set, unset and list commands with the new
5856 * Redefined the Channel Message Payload to include the channel
5857 message flags (equal with private message flags) to support
5858 for example CTCP style messages.
5860 * Defined some of the message (for channel and private message)
5861 flags. Updated the protocol specs and added the flags to the
5862 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5864 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added SilcKeyAgreementStatus type to the key agreement routines
5867 to indicate the current status and error if one occured.
5868 The status types are defined in the lib/silcclient/silcapi.h.
5870 * Added new local command KEY that is used to set and unset private
5871 keys for channels, set and unset private keys for private messages
5872 with remote clients and to send key agreement requests and
5873 negotiate the key agreement protocol with remote client. The
5874 key agreement is supported only to negotiate private message keys,
5875 it currently cannot be used to negotiate private keys for channels,
5876 as it is not convenient for that purpose.
5878 * Fixed a minor pending callback setting bug in the function
5879 silc_client_get_client_by_id_resolve, now the function works.
5880 Affected file lib/silcclient/idlist.c.
5882 * Added function silc_net_get_local_port to get local bound
5883 port by socket. Added to lib/silcutil/silcnet.[ch].
5885 * Added `sockets' and `sockets_count' fields to the SilcClient
5886 object. They hold the sockets of the listenning sockets in
5887 the client. Listenning sockets may be for example the key
5888 agreement server. Affected file lib/silcclient/client.[ch].
5889 Added functions the silc_client_add_socket and the
5890 silc_client_del_socket. They are exported to the application
5893 * Added ~./silc/clientkeys to support other client's public keys.
5895 * Renamed verify_server_key client operation to verify_public_key
5896 and added one argument to indicate the type of the connection
5897 (server, client etc.).
5899 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Added silc_server_connection_auth_request to handle the
5902 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5903 silcd/packet_receive.[ch].
5905 * Added silc_server_send_connection_auth_request into the
5906 silcd/packet_send.c to send the connection auth request packet.
5908 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5911 * Fixed the public key authentication in responder side in the
5912 server. The `auth_data' pointer includes the SilcPublicKey
5913 not the path to the public key. Affected file silcd/protocol.c.
5915 * Implemented the public key authentication in the initiator side
5916 in the server. Affected file silcd/protocol.c.
5918 * Removed the [RedirectClient] config section from the server
5919 configuration. Is not needed and I don't want to implement it.
5921 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Cleaned up the CMODE command in the server. It now works
5924 correctly and supports all the modes defined in the protocol.
5925 Affected file is silcd/command.c.
5927 * Added `hmac_name' field to the SilcChannelEntry in the server
5928 to hold the default HMAC of the channel. It can be set when
5929 creating the channel (with JOIN command). Affected files
5932 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5933 type to indicate the change of the current cipher and hmac
5934 on the channel. Client can safely ignore the <cipher> argument
5935 (if it chooses to do so) since the CHANNEL_KEY packet will
5936 force the channel key change anyway. The <hmac> argument is
5937 important since the client is responsible of setting the new
5938 HMAC and the hmac key into use.
5940 * Fixed the CMODE command in the client library as well.
5942 * Tested CMODE command in router environment successfully.
5944 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Show the version of the remote client (or server) when connecting
5947 to the server. It is logged to the log file. Affected file
5948 is silcd/protocol.c.
5950 * Fixed the KILLED notify handling in the client library. The
5951 client must be removed from all channels when receiving the
5954 Also, do not remove the client entry when giving the KILL
5955 command but when the KILLED notify is received.
5957 * Removed silc_idlist_find_client_by_nickname from the server.
5958 Not needed anymore. Affected files silcd/idlist.[ch].
5960 * Implemented the CHANNEL_CHANGE notify type handling to the
5961 server. Affected file silcd/server.c.
5965 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added silc_server_send_notify_invite to send the INVITE
5968 notify between routers.
5970 * Implemented the INVITE command correctly to the server.
5972 * Implemented the INVITE notify type handling in the server.
5974 * Implemented the INVITE command to the client library and on the
5977 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Added function silc_server_get_client_resolve to find the
5980 client entry by ID from all ID lists and then resolve it
5981 (using WHOIS) if it cannot be found. Affected file is
5984 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Implemented the BAN command to the client library.
5988 * The JOIN command in the server now checks the invite list
5991 * Changed the silc_command_reply_payload_encode_va and the
5992 silc_command_payload_encode_va to support that if argument is
5993 NULL it ignores and checks the next argument. Affected file
5994 lib/silccore/silccommand.c.
5996 * Added silc_server_send_notify_ban to send the BAN notify
5997 type between routers.
5999 * Chaned the silc_notify_payload_encode to support that if
6000 argument is NULL it ignores and checks the next argument.
6001 Affected file lib/silccore/silcnotify.c.
6003 * Tested ban lists in router environment successfully.
6005 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Implemented BAN command to the server, in silcd/command.[ch].
6009 * Removed the BAN and INVITE_LIST modes from the CMODE command
6012 * Added function silc_string_match to regex match two strings.
6013 Affected files lib/silcutil/silcutil.[ch].
6015 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Redefined parts of the SilcChannelEntry in the server to support
6018 the new ban and invite lists.
6020 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Redefined the INVITE command. The same command can be used to
6023 invite individuals to the channel but also to manage the invite
6024 list of the channel (to add to and remove from the invite list).
6025 Updated the protocol specs.
6027 * Added new command SILC_COMMAND_BAN that can be used to manage
6028 the ban list of the channel. Updated the protocol specs.
6030 * Removed the channel modes: the SILC_CMODE_BAN and the
6031 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6032 in the CMODE command. The equivalent features are now available
6033 using INVITE and BAN commands. Updated the protocol specs.
6035 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6036 in the network about change in the current ban list. The notify
6037 type is not used by the client.
6039 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6040 support the invite lists.
6042 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Added new function silc_string_regexify that converts string
6045 including wildcard characters into regex string that can
6046 be used by the GNU regex library. Added into the file
6047 lib/silcutil/silcutil.[ch].
6049 Added silc_string_regex_combine to combine to regex strings
6050 into one so that they can be used as one regex string by
6051 the GNU regex library. Added into the file
6052 lib/silcutil/silcutil.[ch].
6054 Added silc_string_regex_match to match two strings. It returns
6055 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6057 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Imported GNU regex to the soruce tree into lib/contrib.
6060 Fixed some compiler warning from the regex.c.
6062 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Fixed MOTD command in the server to work in router environment.
6066 * Fixed the MOTD command in the client library to support
6067 the server argument in the command.
6069 * Added `nickname_len' argument to the silc_idlist_add_client
6070 in the server, as the `nickname' argument may be binary data
6073 * Added silc_idlist_get_channels to return all channels from
6076 * Implemented LIST command to the server. Affected file is
6079 * Implemented the LIST command to the client library and on the
6082 * Added [<user count>] argument to the LIST command reply.
6083 With private channels the user count is not shown.
6085 * Updated TODO and README.
6087 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * The client entry's data.registered must be TRUE even with
6090 global client entry on global client list. The data.registered
6091 is used to check whether the client is anymore in the network,
6092 for example with WHOWAS command so it must be valid.
6094 * Fixed the WHOWAS command in the server. It now actually works
6095 in router environment. Added function into silcd/command_reply.c
6096 silc_server_command_reply_whowas_save.
6098 * Added silc_idlist_purge function to the silcd/idlist.c
6099 to periodically purge the ID Cache.
6101 * Fixed INFO command in the server. It works now in router
6102 environment. Added <server name> argument to the INFO command
6103 reply. Updated the protocol specs.
6105 * Fixed minor bug in silc_idcache_purge to not purge if the
6106 expire value is zero.
6108 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6109 they were buggy because of the WHOWAS information.
6111 * Fixed local command MSG to handle the async resolving of
6112 the remote client properly. It used to fail the first MSG.
6113 Affected file silc/local_command.c.
6115 * Added `data_len' field to SilcIDCache context.
6117 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Update TODO. Todo in commands in the server.
6121 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6124 used by routers as broadcast packet to inform other routers
6125 about the changed user mode.
6127 Implemented the notify handling in the server. Affected file is
6128 silcd/packet_receive.c. Added the function
6129 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6131 * Added new generic Channel Payload and deprecated the New Channel
6132 Payload. The New Channel Payload is now the generic Channel
6135 * Added new argument `mode' to the silc_server_send_new_channel
6136 as it is required in the Channel Payload now.
6138 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6139 and created a new and real SilChannelPayload to represent the
6140 new generic Channel Payload. Implemented the encode/decode
6141 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6143 * Added silc_server_get_client_channel_list to return the list
6144 of channels the client has joined for WHOIS command reply.
6145 Affected file silcd/server.[ch].
6147 * Implemented the channel list sending in the WHOIS command reply
6148 in server and in the client.
6150 Implemented the channel list displaying on the user interface
6151 as well. Affected file silc/client_ops.c.
6153 * Added silc_channel_payload_parse_list to parse list of Channel
6154 Payloads. It returns SilcDList list of SilcChannelPayloads.
6155 Client for example can use this function to parse the list of
6156 channels it receives in the WHOIS command reply. The caller
6157 must free the list by calling silc_channel_payload_list_free.
6158 Affected files lib/silccore/silcchannel.[ch].
6160 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added one new argument <user mode> to the WHOIS command reply
6163 to return the mode of the user in SILC. Updated the protocol
6166 Implemented it to the server and client.
6168 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Fixed the mode printing on the user interface on joining.
6171 Affected file silc/client_ops.c.
6173 * Implemented the UMODE command and user modes in general to the
6174 client library and to the user interface.
6176 * Implemented the UMODE command to the server.
6178 * The server now sends UNKNOWN_COMMAND error status if client sends
6179 unknown command. Affected file silcd/command.c.
6181 * All server commands now handle the command identifier the right
6182 way when sending the command reply to the client. The client can
6183 use to identify the command replies with the identifier.
6185 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Added silc_server_get_client_route to resolve the route to
6188 the client indicated by the client ID. Affected file is
6191 * Added silc_server_relay_packet as general function to relay
6192 packet to arbitrary destination. This deprecates functions
6193 like _send_private_message_key, _relay_notify etc. Affected
6194 file is silcd/packet_send.[ch].
6196 Removed silc_server_send_key_agreement,
6197 silc_server_send_private_message_key and
6198 silc_server_packet_relay_notify functions from the file
6199 silcd/packet_send.[ch].
6203 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6204 server. Affected file silcd/packet_receive.[ch].
6206 * Implemented the KILL command to the client. Implemented the
6207 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6208 Affected files lib/silcclient/command[_reply].c and
6209 lib/silcclient/client_notify.c. Implemented the KILL notify
6210 printing in the user inteface.
6212 * Fixed a lot silc_parse_nick memory leaks from the client
6213 library in the file lib/silcclient/command.c.
6215 * Changed the silc_server_send_notify_on_channels's `sender'
6216 argument from SilcSocketConnection to SilcClientEntry to
6217 check the sender as entry and not as connection object and not
6218 to send to the client provided as argument. The affected file
6219 is silcd/packet_send.[ch].
6221 * The notify packets that are destined directly to the client used
6222 to not to be processed by the server. Now changed that and the
6223 server processes all notify packets. After relaying the packet
6224 to the client the notify packet is processed in the server.
6226 * The silc_server_free_client_data now checks whether there is
6227 pending outgoing traffic for the client and purges the data to
6228 the network before removing the client entry.
6230 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6233 an client is killed from the SILC Network. Updated the protocol
6236 Added new function silc_server_send_notify_killed to the
6237 silcd/packet_send.[ch].
6239 * Added function silc_server_packet_relay_notify to relay notify
6240 packets that are destined directly to a client. In this case
6241 the server does not process the notify packets but merely relays
6242 it to the client. Affected file silcd/packet_send.[ch].
6244 Added also silc_server_packet_process_relay_notify to check
6245 whereto relay the notify. Affected file is
6246 silcd/packet_receive.[ch].
6248 * Implemented the KILL command to the server.
6252 * Added the backup schema desgined last fall to the protocol
6253 specs for everyone to see. The specification is in the
6254 *-spec-xx.txt draft and the packet type definitions for the
6255 backup routers is in *-pp-xx.txt draft. Thusly, added also
6256 new packet type SILC_PACKET_CELL_ROUTERS.
6258 * A big security problem in the implementation discovered. The
6259 signoff of an client did not cause new channel key generation
6260 which it of course should've done. The channel keys must be
6261 always re-generated when client leaves (or signoffs) the channel.
6262 The silc_server_remove_from_channels funtion now handles
6263 the channel key re-generation.
6265 * Added `sender' argument to the silc_server_send_notify_on_channels
6266 to not to send the client provided as argument. Affected file
6267 silcd/packet_send.[ch].
6269 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Implemented OPER and SILCOPER commands into the server and
6274 * Added silc_auth_verify and silc_auth_verify_data to verify
6275 the authentication directly from the authentication payload.
6276 It supports verifying both passphrase and public key based
6277 authentication. Affected file lib/silccore/silcauth.[ch].
6279 * Added `hash' field to the SilcIDListData structure. It is the
6280 hash negotiated in the SKE protocol. Affected file is
6283 * Slight redesigning of the SilcAuthPayload handling routines.
6284 Do not send SilcPKCS but SilcPublicKey as argument.
6286 * Implemented the public key authentication support to the
6287 serverconfig. The public key is loaded from the provided path
6288 and saved as authentication data to void * pointer. Thus,
6289 changed the unsigned char *auth_data to void *auth_data;
6291 * Fixed SHUTDOWN command to send the reply before the server
6292 is shutdown. :) Affected file silcd/command.c.
6294 * Fixed fatal bug in CONNECT command. The hostname was invalid
6295 memory and server crashed. Affected file silcd/command.c.
6297 * Fixed fatal bug in CLOSE command. The server_entry became
6298 invalid but was referenced later in the command. Affected file
6301 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Fixed fatal bug in failure packet handling. Server ignored
6304 the failure and thus crashed when it came.
6308 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6311 that the command may be executed only once in (about) 2 seconds.
6312 The old SILC_CF_LAG flag is same but allows command bursts up
6313 to five before limiting.
6315 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6316 server code. Various commands now includes the CF_LAG_STRICT
6317 flag to disallow any kind of miss-use of the command.
6319 * Fixed the silc_buffer_unformat to not to allocate any data
6320 if the length of the data is zero. It used to allocate the
6321 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6323 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Changed the format of AdminConnection configuration section
6326 in the server. Added username of the admin to the format.
6327 Affected files silcd/serverconfig.[ch].
6329 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6330 to return admin configuration data by host, username and/or
6333 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Implemented WHOWAS command to the server. Added the functions:
6337 silc_server_command_whowas_parse,
6338 silc_server_command_whowas_send_reply,
6339 silc_server_command_whowas_from_client and
6340 silc_server_command_whowas_from_server
6342 * Added <Client ID> argument to the WHOWAS command reply. Updated
6343 the protocol specs accordingly.
6345 * Implemented WHOWAS command and command_reply to the client
6348 Implemented the WHOWAS printing on the user interface.
6350 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Added new argument to the WHOWAS command reply, the real name.
6353 It is an optional argument. Updated the protocol specs.
6355 * Added SilcIDCacheDestructor callback that is registered when
6356 the SilcIDCache is allocated. The callback is called when
6357 an cache entry in the ID Cache expires, or is purged from the
6358 cache. Added into lib/silccore/idcache.[ch].
6360 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6361 to destruct the client entries when the cache entry expires.
6362 Other ID Cache's in server and in the client library ignores
6365 * If the ID Cache entry's `expire' field is zero then the entry
6366 never expires. Added boolean `expire' argument to the
6367 silc_idcache_add function in the lib/silccore/idcache.[ch].
6368 If it is TRUE the default expiry value is used.
6370 * Added silc_server_free_client_data_timeout that is registered
6371 when client disconnects. By default for 5 minutes we preserve
6372 the client entry for history - for WHOWAS command.
6374 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6376 * Added support to the server to enforce that commands are not
6377 executed more than once in 2 seconds. If server receives
6378 commands from client more frequently, timeout is registered
6379 to process the commands. Affected file silcd/command.c.
6380 Added new function silc_server_command_process_timeout.
6382 * Changed NICK_NOTIFY handling in client library to check that
6383 if the client's nickname was changed, so there is no need to
6384 resolve anything from the server.
6386 * Removed error printing from the WHOIS and IDENTIFY commands.
6387 If error occurs then it is ignored silently in the client library.
6388 The application, however, may map the received error to
6389 human readable error string. The application currently maps
6390 the NO_SUCH_NICKNAME error to string.
6392 * Made the command status message public to the application. Moved
6393 them from lib/silcclient/command_reply.c to
6394 lib/silcclient/command_reply.h. The application can map the
6395 received command status to the string with the
6396 silc_client_command_status_message function.
6398 * Added check to the server to check that client's ID is same
6399 as the Source ID in the packet the client sent. They must
6402 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Added dist-bzip hook to the Makefile.am to make bzip2
6405 compressed distributions.
6407 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Server now enforces the maximum length for the nickname and
6410 the channel as protocol specification dictates. 128 bytes for
6411 nickname and 256 bytes for channel name.
6413 * Moved the WHOIS printing to the application. The client libary
6414 does not print out the WHOIS information anymore, the application
6415 must do it. Renamed silc_client_command_reply_whois_print to
6416 the silc_client_command_reply_whois_save.
6418 The client's idle time is also sent to the application now, and
6419 the idle is shown on screen.
6421 * Added silc_client_command_reply_identify_save to save the
6422 received IDENTIFY entries.
6424 * Do not check for channel private keys in message sending and
6425 reception if the channel does not have the PRIVKEY mode set.
6426 Affected file lib/silclient/client_channel.c.
6428 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6431 just surfaced after chaning the JOIN procedure.
6433 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Added silc_client_get_clients_by_list to get client entries
6436 from Client ID list, that is returned for example by JOIN
6437 and USERS command replies. The application should use this
6438 function for example when JOIN command reply is received to
6439 resolve the clients already on the channel (library does not
6440 do that anymore as USERS command reply is not used in the JOIN
6441 procedure anymore). Affected files lib/silcclient/silcapi.h and
6442 lib/silcclient/idlist.c.
6444 * JOIN command reply and USERS command reply returns now SilcBuffer
6445 pointers instead of unsigned char pointers when returning
6446 the client list and mode list.
6448 * Added <Client ID> argument to the JOIN command reply, mainly
6449 for the server to identify for which client the command was
6450 originally sent. Updated protocol specs accordingly.
6452 * Added SilcDlist private_key pointer to the SilcChannelEntry
6453 in the client to support the channel private keys. Affected
6454 file is lib/silcclient/idlist.h.
6456 * Added SilcChannelPrivateKey argument to the function
6457 silc_client_send_channel_message so that application can choose
6458 to use specific private ke if it wants to. If it is not provided,
6459 the normal channel key is used, unless private keys are set.
6460 In this case the first (key that was added first) is used
6461 as the encryption key.
6463 * Implemented the support for channel private key handling.
6464 Implemented the following functions:
6466 silc_client_add_channel_private_key,
6467 silc_client_del_channel_private_keys,
6468 silc_client_del_channel_private_key,
6469 silc_client_list_channel_private_keys and
6470 silc_client_free_channel_private_keys
6472 Affected file lib/silcclient/client_channel.c.
6474 * Added the support for the private keys in the channel message
6475 sending and encryption and in the message reception and
6476 decryption. Affected funtions are
6477 silc_client_send_channel_message and silc_client_channel_message.
6479 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Added SKE's key verify callback to the client library's
6482 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6484 * Removed the statement that server (or router) must send USERS
6485 command reply when joining to the channel so that the client
6486 knows who are on the channel. Instead, the client list and
6487 client's mode list is now sent in the JOIN command reply to the
6488 client who joined channel. This is better solution.
6490 * Added function silc_server_get_users_on_channel and function
6491 silc_server_save_users_on_channel to the silcd/server.[ch].
6493 * Removed function silc_server_command_send_users from the
6496 * Do not show topic on the client library anymore. The topic is
6497 sent in the command reply notify to the application and the
6498 application must show the topic now.
6500 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added client searching by nickname hash into the IDENTIFY and
6503 WHOIS commands in the server as they were clearly missing from
6504 them. Affected file is silcd/command.c.
6506 * Fixed a bug in private message receiving in the client library.
6507 The remote ID was freed and it wasn't supposed, now it is
6510 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Minor fix to the channel payload; allocate the data area, as it
6513 needs to be of specific length.
6515 * If the key agreement port is zero then the operating
6516 system will define the bound port. Affected files are
6517 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6519 * Added new function silc_channel_payload_decrypt into the file
6520 lib/silccore/silcchannel.[ch].
6522 * Moved the channel message etc, check from silc_packet_decrypt
6523 to applications. The library calls now a generic
6524 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6525 when the packet is either normal or special. This was done to
6526 allow more wide range of checking that was not allowed when
6527 the code was in library. Now applications can do virtually any
6528 checks to the packet and return to the library the decision how
6529 the packet should be processed. Affected files are
6530 lib/silccore/silcpacket.[ch].
6532 Added silc_server_packet_decrypt_check to the server and
6533 silc_client_packet_decrypt_check to the client library.
6535 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6536 to send with specified source and destination information.
6538 * Channel message delivery between routers was broken after the
6539 channel key distribution was fixed earlier. The channel key
6540 was used be to distributed to other routers as well which is not
6541 allowed by the protocol. Now this is fixed and channel keys
6542 really are cell specific and the channel message delivery between
6543 routers comply with the protocol specification.
6545 * Fixed various commands in server to check also the global list
6546 for the channel entry and not just the local list. The affected
6547 file silcd/command.c.
6549 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6551 * Added assert()s to buffer formatting and unformatting routines
6552 to assert (if --enable-debug) when error occurs. Affected
6553 file: lib/silcutil/silcbuffmt.c.
6555 * Changed to auto-reconnect to check whether the remote host is
6556 router and register the re-connect timeout if it is. It used
6557 to check that whether we are normal server, but router must do
6558 auto-reconnect with another router as well. Affected file
6561 * Removed the [<key len>] option from CMODE command as the cipher
6562 name decides the key length, nowadays. See the defined ciphers
6563 from the protocol specification.
6565 * Added [<hmac>] option to the CMODE command to define the HMAC
6566 for the channel. Added SILC_CMODE_HMAC channel mode.
6568 * Added [<hmac>] option for the JOIN command so that user can
6569 select which HMAC is used to compute the MACs of the channel
6572 * Added Hmac field to the Channel Message Payload. The integrity
6573 of plaintext channel messages are now protected by computing
6574 MAC of the message and attaching the MAC to the payload. The
6575 MAC is encrypted. Now, it is clear that this causes some
6576 overhead to the size of the packet but rationale for this is that
6577 now the receiver can verify whether the channel message decrypted
6578 correctly and also when private keys are set for the channel the
6579 receiver can decrypt the packet with several keys and check from
6580 the MAC which key decrypted the message correctly.
6582 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6583 lib/silccrypt/silccipher.[ch].
6585 * Added silc_hash_len to return the digest length into the
6586 lib/silcrypt/silchash.[ch].
6588 * Rewrote parts of Silc Channel Payload interface in the
6589 lib/silccore/silcchannel.[ch]. The encode function now also
6590 encrypts the packet and parse function decrypts it.
6592 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Fixed a minor formatting bug in the SKE's key material processing.
6595 It actually might have processed the keys wrong way resulting
6598 * Redefined the mandatory HMAC algorithms and added new algorithms.
6599 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6600 and hmac-md5 truncated to 96 bits. The mandatory is now
6601 hmac-sha1-96. Rest are optional (including the one that used
6602 to be mandatory). Rationale for this is that the truncated HMAC
6603 length is sufficient from security point of view and can actually
6604 make the attack against the HMAC harder. Also, the truncated
6605 HMAC causes less overhead to the packets. See the RFC2104 for
6608 * Added new [hmac] configuration section. The SKE used to use
6609 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6610 is of course wrong. The official names that must be proposed in
6611 the SKE are the ones defined in the protocol specification
6612 (hmac-sha1-96 for example). The user can configure any hmac
6613 using any hash function configured in the [hash] section. At
6614 least, the mandatory must be configured.
6616 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6618 * Added HMAC list to the SKE proposal list. It has now both
6619 hash algorithm list and HMAC list. This makes the protocol
6620 incompatible with previous versions. The SKE now seems to work
6621 the way it is supposed to work, for the first time actually.
6623 * Defined plain Hash algorithms to the protocol specification.
6626 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Implemented support for key agreement packets into the server.
6629 Added functions silc_server_key_agreement and
6630 silc_server_send_key_agreement. Other than these functions,
6631 server has nothing to do with this packet.
6633 * Added support for private message key packets into the server.
6634 Added functions silc_server_private_message_key and
6635 silc_server_send_private_message_key.
6639 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6640 called in the protocol's final callback instead in the END
6641 protocol state. This makes a little more sense and in the same
6642 time in client we can use the same protocol routines for normal
6643 key exchange and to key agreement packet handling as well.
6645 * Added to both client's and server's KE protocol context the
6646 SilcSKEKeyMaterial pointer to save the key material. We will
6647 bring the key material to the protocol's final callback by doing
6648 this. The final callback must free the key material.
6650 * Added SKE's packet_send callback into client's KE protocol
6651 context so that the caller can choose what packet sending function
6652 is used. This way we can use different packet sending when
6653 doing normal SKE when doing key agreement packet handling (in
6654 the key agreement packet handling we do not want to encrypt
6657 * Implemented the responder side of the key agreement routines
6658 in the client. The client can now bind to specified port and
6659 accept incoming key negotiation. The key material is passed
6660 to the application after the protocol is over.
6662 * Implemented the processing of incoming Key Agreement packet
6663 in the client. Added function silc_client_key_agreement to
6666 * Implemented the intiator side of the key agreement routines
6667 in the client. The client can now initiate key agreement with
6668 another remote client. The key material is passed to the
6669 application after the protocol is over.
6671 * Created client_keyagr.c to include all the key agreement
6674 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6675 SILC_TASK_CALLBACK except that it is not static.
6677 * Created client_notify.c and moved the Notify packet handling
6678 from the client.[ch] into that file.
6680 * Created client_prvmsg.c and moved all private message and
6681 private message key routines from the client.[ch] into that file.
6683 * Create client_channel.c and moved all channel message and
6684 channel private key routines from the client.[ch] into that file.
6686 * Changed silc_client_get_client_by_id_resolve to resolve with
6687 WHOIS command instead of IDENTIFY command, in the file
6688 lib/silclient/idlist.c.
6690 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Implemented the SKE's responder side to the Client library.
6694 * When FAILURE is received to the protocol do not trust it
6695 blindly. Register a timeout to wait whether the remote closes
6696 the connection as it should do it, only after that process the
6697 actual failure. This was changed to both client and server.
6699 * Added client_internal.h to include some of the structures
6700 there instead of client.h in lib/silcclient/.
6702 * Added function silc_task_unregister_by_callback to unregister
6703 timeouts by the callback function.
6705 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Some "Incomplete WHOIS info" errors has been appearing on the
6708 log files. Took away the entry->userinfo check from WHOIS
6709 reply sending. The entry->userinfo is now " " if client did not
6710 provide one. I thought this was fixed earlier but something
6711 is wrong still. Let's see if the error still appears.
6713 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Fixed a minor bug in the login when the channel key is
6716 re-generated in the server. It used to generate the key in
6717 wrong order and thus caused problems in the channel traffic.
6719 * Fixed a minor bug in channel key distsribution after
6720 KICK command. The key was not sent to the router even though
6723 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Added silc_ske_process_key_material_data as generic routine
6726 to process any key material as the SILC protocol dictates. The
6727 function is used by the actual SKE library but can be used by
6728 applications as well. This relates to the private message keys
6729 and the channel private keys since they must be processed the
6730 same way the normal SILC session keys. The protocol dictates
6731 this. Affected files: lib/silcske/silcske.[ch].
6733 Added also silc_ske_free_key_material to free the
6734 SilcSKEKeyMaterial structure.
6736 * Defined silc_cipher_set_key function to set the key for
6737 cipher without using the object's method function. The affected
6738 files: lib/silccrypt/silccipher.[ch].
6740 * Implemented silc silc_client_add_private_message_key,
6741 silc_client_add_private_message_key_ske,
6742 silc_client_del_private_message_key,
6743 silc_client_list_private_message_keys and
6744 silc_client_free_private_message_keys functions in the
6747 Added functions silc_client_send_private_message_key to send
6748 the Private Message Key payload and silc_client_private_message_key
6749 to handle incoming Private Message Key payload.
6751 * Added Cipher field to the Private Message Key payload to set
6752 the cipher to be used. If ignored, the default cipher defined
6753 in the SILC protocol (aes-256-cbc) is used.
6755 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Removed lib/silcclient/ops.h file.
6759 Redefined parts of the SILC Client Library API. Created new
6760 file silcapi.h that deprecates the ops.h file and defines the
6761 published Client Library API. Defined also private message key
6762 API and channel private key API into the file.
6764 This is the file that the application must include from the
6765 SILC Client Library. Other files need not be included by
6766 the application anymore.
6768 * Added new key_agreement client operation callback and also
6769 defined the Key Agreement library API for the application.
6771 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6774 is used by clients to request key negotiation between another
6775 client in the SILC network. If the negotiation is started it
6776 is performed using the SKE protocol. The result of the
6777 negotiation, the secret key material, can be used for example
6778 as private message key.
6780 Implemented the Key Agreement payload into the files
6781 lib/silccore/silauth.[ch].
6783 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Redefined ciphers for the SILC protocol. Added some new ciphers
6786 and defined the key lengths for the algorithms. Changed the
6787 code accordingly. The default key length is now 256 bits.
6789 * Fixed SKE key distribution function silc_ske_process_key_material
6790 when the key length is more than 128 bits. The default key
6791 length in SILC is now 256 bits.
6793 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6794 to indicate unsupported algorithm.
6796 * Renamed rijndael.c to aes.c and all functions as well.
6798 * Fixed a long standing channel key setting bug in client library.
6799 Weird that it has never surfaced before.
6801 * Fixed bug in channel deletion. If the entire channel is removed
6802 then it must also delete the references of the channel entry
6803 from the client's channel list as the client's channel entry and
6804 the channel's client entry share same memory.
6806 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Implemented CONNECT and SHUTDOWN commands in the client.
6810 * Implemented CLOSE command to the client.
6812 * Added the function silc_idlist_find_server_by_name into the
6813 files silcd/idlist.[ch].
6815 Added the function silc_idlist_find_server_by_conn into the
6816 files silcd/idlist.[ch].
6818 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * DIE command was renamed to SHUTDOWN. Updated the both code
6823 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6824 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6826 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6829 * Added function silc_server_create_connection function to create
6830 connection to remote router. My server implementation actually
6831 does not allow router to connect to normal server (it expects
6832 that normal server always initiates the connection to the router)
6833 so the CONNECT command is only good for connecting to another
6836 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6839 or some other client was kicked from the channel.
6841 Implemented the handling of the notify type to both client
6844 Implemented silc_server_send_notify_kicked to send the KICKED
6845 notify. It is used to send it to the server's primary router.
6847 * Implemented the KICK command into server and client.
6849 * Added `query' argument to the silc_idlist_get_client function
6850 to indicate whether to query the client from server or not if
6853 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6854 to indicate that the client is not channel founder.
6858 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Removed the rng context from SilcPacketContext structure and
6861 changed that the packet routine uses the Global RNG API.
6863 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Added support for quit message that client can "leave" on the
6866 channel when it quits the SILC. It is ditributed inside the
6867 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6869 Added silc_server_free_client_data that will take the
6870 signoff message as argument.
6872 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6874 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Updated parts of the protocol specification to keep it up
6879 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6882 payloads in one packet.
6884 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6885 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6886 use now the new List flag.
6888 * Also deprecated the following packet types: REPLACE_ID,
6889 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6891 * Added list support for Notify packet in server.
6893 * Added silc_server_send_notify_channel_change to send the
6894 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6895 the silc_server_send_replace_id.
6897 * Added silc_server_send_notify_nick_change to send the
6898 NICK_CHANGE notify type. Deprecates the function
6899 silc_server_send_replace_id.
6901 * Added silc_server_send_notify_join to send the JOIN notify type.
6902 Deprecates the function silc_server_send_new_channel_user.
6904 * Added silc_server_send_notify_leave to send LEAVE notify type.
6905 Deprecates the function silc_server_send_remove_channel_user.
6907 * Added silc_server_send_notify_cmode and
6908 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6909 types. Deprecates the silc_server_send_set_mode function.
6911 * Added SERVER_SIGNOFF notify type to indicate that server has
6912 quit. This means that all clients on the channel from that
6913 server will drop. This can be also used when netsplit happens.
6915 Deprecated REMOVE_ID packet type since it is not needed anymore
6918 Added silc_server_send_notify_server_signoff to send the
6919 SERVER_SIGNOFF notify type. Deprecates the function
6920 silc_server_send_remove_id.
6922 Added also silc_server_send_notify_signoff to send the
6923 SIGNOFF notify type.
6925 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6926 SILC protocol from this day on. Changed the protocol
6927 specification as well.
6929 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6930 notify type. It is used between routers to notify about
6931 topic changes on a channel.
6933 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6936 * Partly updated the protocol specification to comply with the
6937 changes now made. It is still though a bit outdated.
6939 * The JOIN notify type now takes one extra argument <Channel ID>.
6940 The packet used to be destined to the channel but now the
6941 JOIN type may be sent as list thus it is impossible to
6942 destine it to any specific channel. By adding this argument
6943 it is again possible.
6945 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Added CREDITS file. The CHANGES and CREDITS file will appear
6948 in the distribution as well.
6950 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6953 types in the server's silcd/packet_receive.c.
6955 * Implemented CMODE and CUMODE to work in router environment.
6957 * Fixed minor encoding and decoding buglet from the
6958 lib/silccore/silcmode.c.
6960 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6963 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6965 * Changed all SilcConfigServer* and silc_config_server* to
6966 SilcServerConfig* and silc_server_config*, respectively.
6969 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Associated the ID (client or server ID) to the Authentication
6972 Payload to avoid any possibility of forging. Updated the
6973 protocol specification and the code accordingly.
6975 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * The RSA key length is now save to the RsaKey context in the
6978 key generation process in lib/silccrypt/rsa.c. The key length
6979 is now used to figure out the maximum size of the block allowed
6980 to be encrypted/signed.
6982 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6983 is equivalent to the silc_mp_mp2bin but does not allocate any
6986 * Changed silc_mp_mp2bin API to take length argument. If it is
6987 non-zero then the buffer is allocated that large. If zero, then
6988 the size is approximated using silc_mp_sizeinbase, which however
6991 * Created Global RNG API which is global RNG that application can
6992 initialize. After initializing, any routine anywhere in the
6993 code (including library) can use RNG without allocating a new
6994 RNG object. This was done to allow this sort of use of the
6995 RNG in code that has no chance to allocate RNG object. All
6996 applications currently allocate this and many routines in the
6997 library use this. Affected file lib/silccrypt/silcrng.[ch].
6999 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7000 it to use the Global RNG API.
7002 * Defined Authentication Payload into protocol specification that
7003 is used during SILC session to authenticate entities. It is
7004 used for example by client to authenticate itself to the server
7005 to obtain server operator privileges.
7007 Implemented this payload into the lib/silccore/silcauth.[ch].
7008 Implemented also routines for public key based authentication
7009 as the new protocol specification dictates.
7011 Moved definitions of different authentication methods from
7012 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7014 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7015 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7016 silc_pkcs_verify_with_hash functions into the file
7017 lib/silccrypt/silcpkcs.[ch].
7019 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * The client entry's userinfo pointer must be always valid.
7022 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7023 will fail since it requires the userinfo. Now, the userinfo
7024 is allocated as "" if actual userinfo does not exist. Actually,
7025 it must exist and it is totally Ok to drop client connections
7026 that does not announce the userinfo. However, we will make
7027 this workaround for now.
7029 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7030 to return the remote port by socket.
7032 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7035 SILC_SERVER_PENDING_EXEC and added an new macro
7036 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7037 data or when error occurs while processing the pending command.
7039 Added new argument `destructor' into silc_server_command_pending
7040 and to the SilcServerCommandPending object. This destructor is
7041 now called after calling the pending callback or if error occurs
7042 immediately. If error occurs the actual pending callback won't
7043 be called at all - only the destructor. The destructor may be
7044 NULL if destructor is not needed.
7046 All this applies for client library code as well. Similar
7047 changes were made there as well for the pending commands.
7049 In the client, the application must now allocate the
7050 SilcClientCommandContext with the silc_client_command_alloc
7053 * Added reference counter to the SilcServerCommandContext. Added
7054 function silc_server_command_alloc and silc_server_command_dup
7057 Same type of functions added to the client library for the same
7060 * Removed the cmd_ident from IDListData away since it is now
7061 global for all connections. It is the command identifier used
7062 in command sending and with pending commands. The affected file
7065 * Added reference counter to the SilcSocketConnection objecet to
7066 indicate the usage count of the object. The object won't be
7067 freed untill the reference counter hits zero. Currently only
7068 server uses this, and client ignores it. The client must be
7069 set to use this too later. The affected files are
7070 lib/silccore/silcsockconn.[ch]. Added also the function
7071 silc_socket_dup to increase the reference counter.
7073 This was mainly added because it is possible that the socket
7074 is removed underneath of pending command or other async
7075 operation. Now it won't be free'd and proper DISCONNECTING
7076 flags, etc. can be set to avoid sending data to connection that
7077 is not valid anymore.
7079 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7080 the connection. After that it sets SILC_SET_DISCONNECTED.
7081 It is, however, possible that the socket data is not still freed.
7082 The silc_server_packet_process now checks that data is not
7083 read or written to connection that is DISCONNECTED. The socket
7084 get's freed when the reference counter hits zero.
7086 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Changed the client operation API: channel_message operation's
7089 `sender' is now the client entry of the sender, not the nickname
7090 and the `channel' is the channel entry, not the channel name.
7092 In the private_message operation the `sender' is now also the
7093 client entry of the sender not the nickname.
7095 Affected file is lib/silcclient/ops.h and all applications
7096 using the client operations.
7098 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Moved the calling of ops->connect() from connect_to_server_final
7101 into receive_new_id functin since that is the point when the
7102 client is actually allowed to send traffic to network. The
7103 affected file is lib/silcclient/client.c.
7105 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7108 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7109 (if needs broadcasting) instead of broadcasting the packets one
7110 by one which would make a burst in the network traffic.
7112 * Added `broadcast' argument to the functions in silcd/server.[ch]
7113 silc_server_create_new_channel[_with_id] to indicate whether
7114 to send New Channel packet to primary router.
7116 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added new function into the silcd/server.[ch] files:
7119 silc_server_create_new_channel_with_id to create new channel with
7120 already existing Channel ID.
7122 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7123 lib/silccore/silcpacket.h. This packet is used t send list of
7124 Set Mode payloads inside one packet. Server uses this to set
7125 the modes for the channels and clients on those channels, that it
7126 announced to the router when it connected to it. The protocol
7127 specification has been updated accordingly.
7129 * The silc_server_new_channel did not handle the packet coming
7130 from normal server as it normally does not send that. However,
7131 when it announces its channels it does send it. Implemented
7132 the support for that.
7134 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7135 into the file lib/silccore/id.h.
7137 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Fixed memory leaks in the functions silc_idlist_del_client,
7140 silc_idlist_del_channel and silc_idlist_del_server in the file
7141 silcd/idlist.c. All of those leaked like a sieve.
7143 * Fixed some small memory leaks in the client's function
7144 silc_client_notify_by_server.
7146 * Added functions into silcd/server.c: silc_server_announce_clients,
7147 silc_server_announce_channels and silc_server_announce_server.
7148 These functions are used by normal and router server to announce
7149 to its primary router about clients, channels and servers (when
7150 router) that we own. This is done after we've connected to the
7153 These functions effectively implements the following packet types:
7154 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7155 and SILC_PACKET_NEW_ID_LIST.
7157 * Added new functions into the silcd/packet_receive.[ch]:
7158 silc_server_new_id_list, silc_server_new_channel_list and
7159 silc_server_new_channel_user_list to handle the incoming
7160 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7162 * Added support of changing Channel ID in the function
7163 silc_server_replace_id. If the server that announces a channel
7164 to the router already exists in the router (with same name but
7165 with different Channel ID), router is responsible to send
7166 Replace ID packet to the server and force the server to change
7167 the Channel ID to the one router has.
7169 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7170 client that the Channel ID has been changed by the router. The
7171 normal server sends this to the client. Client must start using
7172 the new Channel ID as the channel's ID.
7174 Implemented handling of this new type into lib/silcclient/client.c
7175 into the function silc_client_notify_by_server.
7177 * Added new function silc_idlist_replace_channel_id into the files
7178 silcd/idlist.[ch] to replace the Channel ID.
7180 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Call silc_server_command_identify_check always when processing
7183 the IDENTIFY command in silcd/command.c
7185 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7188 send keepalive packets. The packet can be sent by clients,
7189 servers and routers.
7191 Added function silc_socket_set_heartbeat into the file
7192 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7193 If not set, the heartbeat is not performed. The actual
7194 heartbeat is implemented in the low level socket connection
7195 library. However, application is responsible of actually
7198 Added silc_server_send_heartbeat to send the actual heartbeat
7199 packet into silcd/packet_send.[ch]. Server now performs
7200 keepalive with all connections.
7202 * Added silc_task_get_first function into lib/silcutil/silctask.c
7203 to return the timeout task with shortest timeout. There was a bug
7204 in task unregistration that caused problems. TODO has been
7205 updated to include that task system must be rewritten.
7207 * The client library will now resolve the client information when
7208 receiving JOIN notify from server for client that we know but
7209 have incomplete information.
7211 * Rewrote parts of silc_server_remove_from_channels and
7212 silc_server_remove_from_one_channel as they did not remove the
7213 channel in some circumstances even though they should've.
7215 * Encryption problem encountered in server:
7217 The LEAVE command used to send the Channel Key packet to the
7218 router immediately after generating it. However, the code
7219 had earlier sent Remove Channel user packet but not immediately,
7220 ie. it was put to queue. The order of packets in the router
7221 was that Channel Key packet was first and Remove Channel User
7222 packet was second, even though they were encrypted in the
7223 reverse order. For this reason, MAC check failed. Now, this
7224 is fixed by not sending the Channel Key packet immediately but
7225 putting it to queue. However, this is more fundamental problem:
7226 packets that are in queue should actually not be encrypted
7227 because packets that are sent immediately gets encrypted
7228 actually with wrong IV (and thus MAC check fails). So, packets
7229 that are in queue should be encrypted when they are sent to
7230 the wire and not when they put to the queue.
7232 However, the problem is that the current system has not been
7233 designed to work that way. Instead, the packet is encrypted
7234 as soon as possible and left to the queue. The queue is then
7235 just purged into wire. There won't be any fixes for this
7236 any time soon. So, the current semantic for packet sending
7239 o If you send packet to remote host and do not force the send
7240 (the packet will be in queue) then all subsequent packets to the
7241 same remote host must also be put to the queue. Only after the
7242 queue has been purged is it safe again to force the packet
7245 o If you send all packets immediately then it safe to send
7246 any of subsequent packets through the queue, however, after
7247 the first packet is put to queue then any subsequent packets
7248 must also be put to the queue.
7250 Follow these rules and everything works fine.
7252 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Added new function silc_server_remove_clients_by_server to
7255 remove all client entries from ID list when the server connection
7256 is lost. In this case it is also important to invalidate all
7257 client entires as they hold the invalid server entry. This
7258 fixes fatal bug when server has lost connection and will reconnect
7261 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7263 * Made some sanity checks to silc_server_daemonise like to check
7264 whether the requested user and group actually exists.
7266 * Added sanity check to SKE's silc_ske_responder_finish to check
7267 that the public and private key actually is valid.
7269 * Invalidate the client's nickname when receiving Replace ID
7270 packet and the Client ID is being replaced. This means that the
7271 server will query the nickname if someone needs it (client)
7274 * Sort the ID Cache in client library when the ID Cache data
7275 has changed (needs sorting).
7277 * Do not allow for SILC client to create several connections to
7278 several servers. The client does not support windows right now
7279 and generating multiple connections causes weird behaviour.
7281 Irssi-silc client does support windows and can handle several
7282 connections without problems, see: www.irssi.org and SILC plugin.
7284 * Fixed some places where client was added to the IDList. The
7285 rule of thumb is following (in order to get everything right):
7286 If the client is directly connected local client then the
7287 `connection' argument must be set and `router' argument must be
7288 NULL to silc_idlist_add_client function. If the client is not
7289 directly connected client then the `router' argument must
7290 bet set and the `connection' argument must be NULL to the
7291 silc_idlist_add_client function.
7293 * The funtion silc_server_packet_send_local_channel actually did
7294 not check whether the client was locally connected or not. It
7295 does that now. Fixed a bug related to LEAVE command.
7297 * Fixed Remove Channel User payload parsing bug in server's
7298 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7300 * The server's silc_server_save_channel_key now checks also the
7301 global ID list for the channel as it might not be in the local
7302 list. Fixed a bug related to LEAVE command.
7304 * Is this the end of the [<unknown>] buglet that has been lurking
7305 around for a long time? A little for loop fix in server's
7306 silc_server_command_whois_parse that is used by both IDENTIFY
7307 and WHOIS command. At least, this was a clear bug and a cause
7308 of one type of [<unknown>] buglet.
7310 * WHOIS and IDENTIFY commands call the function
7311 silc_server_command_[whois/identify]_check function even if
7312 we are not router server.
7314 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Added --with-gmp configuration option. If set the GMP
7317 is always compiled in the SILC source tree. If not set then
7318 it is checked whether the system has the GMP3 installed. If
7319 it has then the GMP won't be compiled (the system's headers
7320 and library is used), if it doesn't have it then the GMP is
7321 compiled in the SILC source tree.
7323 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * Changed RSA private exponent generation to what PKCS #1
7326 suggests. We try to find the smallest possible d by doing
7327 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7328 not security fix but optimization.
7330 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Added new config entry [Identity] to fork the server and run
7333 it as specific user and group. A patch from Bostik.
7335 * Imported Dotconf configuration library into lib/dotconf.
7336 This will be used to create the SILC configuration files later.
7337 It will appear in the distsribution after this commit.
7339 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * A big code auditing weekend happening. Auditing code for
7342 obvious mistakes, bugs and errors. Also, removing any code
7345 Removed files for being obsolete:
7347 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7348 inline in the file lib/silcutil/silcbuffer.h)
7350 o lib/silcutil/silcbufutil.c (the header has inline versions)
7352 Changed code to fix possible error conditions:
7354 o The buffer formatting routines now check that the destination
7355 buffer really has enough space to add the data. This applies for
7356 both buffer formatting and unformatting
7357 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7358 unformatting was changed to accomodate following rules:
7359 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7360 sent to the function while XXX_*STRING will not allocate or copy
7361 the data into the buffer. Instead it sets the pointer from the
7362 buffer into the pointer sent as argument (XXX_*STRING used to
7363 require that the pointer must be allocated already). This change
7364 makes this whole thing a bit more consistent and more optimized
7365 (note that the data returned in the unformatting with XXX_*STRING
7366 must not be freed now). The routines return now -1 on error.
7368 o Tried to find all code that use buffer_format and buffer_unformat
7369 and added return value checking to prevent formatting and
7370 especially unformatting errors and possible subsequent fatal
7373 o Changed ske->x and ske->KEY to mallocated pointers in
7374 lib/silcske/silcske.h. Fixed possible data and memory leak.
7376 o Added return value checking to all *_parse* functions. Fixed
7377 many memory leaks as well.
7379 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7380 so that buffer overflows would not happen. All code now also
7381 checks the return value as it can fail.
7383 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * Added reconnection support to server if the normal server looses
7386 its connection to the router (for example if router is rebooted).
7387 The server performs normal reconnection strategy implemented
7388 to the server. Affected file silcd/server.c.
7390 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Added new packet type SILC_PACKET_SET_MODE that is used to
7393 distribute the information about changed modes (for clients,
7394 channels and clients channel modes) to all routers in the
7395 network. Updated the protocol specification accordingly.
7397 Added functions into silcd/packet_send.c and
7398 silcd/packet_receive.c: silc_server_send_set_mode,
7399 silc_server_set_mode.
7401 Added new files silcmode.[ch] into lib/silccore that implements
7402 the encoding and decoding of Set Mode Payload. Added new type
7403 SilcSetModePayload. Moved the definitions of different modes
7404 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7406 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Oops, a little mistake in server's connection authentication
7409 protocol. The protocol is not ended with FAILURE but with
7410 SUCCESS if the authentication is Ok. :) Affected file is
7413 * Implemented NICK_CHANGE notify handling in server in the file
7414 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7415 the local clients on the channel. After the changing nickname
7416 in router environment snhould work and the [<unknown>] nickname
7417 should appear no more.
7419 The silc_server_replace_id function that receives the Replace ID
7420 payload now sends the NICK_CHANGE notify type also in the file
7421 silcd/packet_receive.c
7423 * Changed WHOIS and IDENTIFY command to support the maximum amount
7424 of arguments defined in protocol specs (3328 arguments). This
7425 fixed a bug that caused problems when there were more than three
7428 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7430 * Added extra parameter, command identifier, to the
7431 silc_client_send_command so that explicit command identifier
7434 Changed that ID list routines uses specific command identifier
7435 when sending WHOIS/IDENTIFY requests to the server so that they
7436 can be identified when the reply comes back.
7438 Affected files lib/silcclient/command.[ch],
7439 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7441 * Added `sender' argument to silc_server_packet_send_to_channel
7442 to indicaet the sender who originally sent the packet to us
7443 that we are now re-sending. Ignored if NULL. Affected file
7444 silcd/packet_send.[ch].
7446 * Added some server statistics support in silcd/server_internal.h
7447 SilcServerStatistics structure and around the server code. Also
7448 send some nice statistics information when client is connecting
7451 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Fixed channel ID decoding in server's JOIN command reply in
7454 silcd/command_reply.c
7456 * Fixed braodcasting of replace ID payload to not to send it if
7457 we are standalone server in silcd/packet_receive.c.
7459 * Fixed all channel message sending routines to not to send
7460 packets to clients that has router set, since they are routed
7461 separately in the same function earlier. Affects file
7462 silcd/packet_send.c and all channel packet sending functions.
7464 * In USERS reply, res_argv[i] are not allocated, the table
7465 is allocated. Thus changed that free the table, not its
7468 * In server's whois_check and identify_check if the client is
7469 locally connected do not send any WHOIS commands - they are not
7472 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7474 * Fixed some minor bugs in client when sending WHOIS command. The
7475 arguments was in wrong order.
7477 * Removed statis function add_to_channel from server in
7478 silcd/command.c that was previously used with the joining but
7481 * Tested USERS command in router environment successfully with two
7482 routers, two servers and two clients.
7484 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7486 * Reorganized the USERS command and command reply in client library
7487 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7488 When the command is given by user we register a pending command
7489 callback that will reprocess the command after the reply has been
7490 received from the server. When reprocessing the packet we then
7491 display the information. Thus, the USERS information is displayed
7492 now in the command callback instead of in the command reply
7493 callback. The processing of the command is same as previously
7494 when server has sent the command reply in the JOINing process.
7496 * Added to USERS command in silcd/command_reply.c to join the client,
7497 we didn't use to know about, to the channel after we've created
7498 a client entry for it. Also, for clienet we did know already still
7499 check whether it is on the channel or not and add it if not.
7501 * Removed silc_server_command_join_notify as the function and its
7504 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Changed the client's pending command handling to the same as the
7507 server's pending command handling. It is also now possible to
7508 execute command reply functions from other command reply
7509 function as the function callbacks for commands and command
7510 replies are one and same. The pending commands are not static
7511 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7512 in client connection context. Thus, pending commands are server
7513 connection specific as it is convenient.
7515 Changed the function silc_client_command_pending and
7516 silc_client_command_pending_del and added new function
7517 silc_client_command_pending_check. Removed the
7518 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7521 * Added cmd_ident, current command identifier, to the client
7522 connection context in lib/silcclient/client.h to keep track on
7523 command identifiers used in command sending. Client's command reply
7524 function handling now supports the mandatory command identifiers.
7526 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7527 funtions in client to fully support pending command callbacks.
7529 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7530 as one of the arguments to the application in the command reply
7533 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7534 before first releasing SILC but came back. Now it is removed again
7535 and should come back nomore. The FORWARDED flag was used only
7536 by the JOINing procedure by forwarding the command packet to router.
7537 Now, the JOINing procedure has been changed to more generic (due
7538 to various router environment issues) and FORWARDED is not needed
7539 anymore for anything. The protocol specification is yet to be
7542 Now, removed silc_server_packet_forward from server and the flag
7543 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7545 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Renamed NAMES command to USERS command. The NAMES was named that
7548 due to historical reasons. Now it is renamed. Also, rewrote
7549 parts of the USERS command. The nickname list is not sent anymore
7550 by the server. Only Client ID and mode lists are sent in the USERS
7551 command. Changed this also to the protocol specification.
7553 The client now resolves the names and stuff after it receives
7554 the USERS list from the server when joining to the channel.
7556 * WHOIS and IDENTIFY commands has been changed to support multiple
7557 Client ID's per command. One can now search for multiple users
7558 in the network by sending only one WHOIS or IDENTIFY command.
7559 Changed the code and the protocol specifications.
7561 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7562 uses silc_server_command_whois_parse to parse the request. */
7564 * If normal server, do not parse the WHOIS and IDENTIFY requests
7565 before sending it to the router. Saves some time.
7567 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7569 * Fixed JOIN command on client library. Wrong number of arguments
7570 used to crash the client.
7572 * Added silc_server_channel_has_global function to check whether
7573 channel has global users or not.
7575 * Added silc_server_channel_has_local function to check whether channel
7576 has locally connected clients on the channel.
7578 * The silc_server_remove_from_one_channel now checks whether the
7579 channel has global users or not after given client was removed from
7580 the channel. It also checks whether the channel has local clients
7581 on the channel anymore. If it does not have then the channel entry
7582 is removed as it is not needed anymore.
7584 * The silc_server_notify now checks on JOIN notify whether the joining
7585 client is one of locally connected or global. If it is global then
7586 the channel has now global users on the channel and that is marked
7587 to the channel entry. Also, it now saves the global client to
7588 global list who is joining and JOINs it to the channel. This is
7589 for normal server, that is.
7591 Changed silc_server_send_notify_on_channel,
7592 silc_server_packet_relay_to_channel and
7593 silc_server_packet_send_to_channel check if we are normal server
7594 and client has router set (ie. global client) do not send the
7595 message to that client, as it is already routed to our router.
7597 * Implemented LEAVE notify type handling in silc_server_notify
7600 * Tested LEAVE command in router environment successfully. Tested
7601 with two routers, two servers and two clients.
7605 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7607 * Implemented SIGNOFF notify type handling in silc_server_notify
7610 * silc_server_remove_id now removes the client entry from all channels
7611 it has joined and thusly sends SIGNOFF notify type.
7613 * Rewrote the NAMES list generation in server by removing two excess
7614 loops. The lists are created now inside one loop.
7616 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * silc_server_remove_channel_user checks now also global list
7619 for channel and client.
7621 * silc_server_new_channel_user checks now both local and global
7622 list for channel and client. Fixed a bug in client id decoding.
7623 Used to decode wrong buffer.
7625 * silc_server_channel_message checks now both local and global
7626 list for channel entry.
7628 * Tested channel joining (hence JOIN) in router environment
7629 successfully. Tested with two routers, two servers and two
7632 * Tested channel message sending in router environment successfully.
7634 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Added silc_server_save_channel_key into server.[ch] to save the
7637 received channel key in Channel Key payload processing. It is
7638 also used in JOIN command reply handling.
7640 Equivalent function silc_client_save_channel_key added into
7641 client.[ch] into client library.
7643 * Changed JOIN command reply to send information whether the channel
7644 was created or not (is existing already) and the channel key
7645 payload. Changed protocol specs accordingly.
7647 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7648 the request was sent by ID and not by nickname. Crashed on
7651 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7654 now correctly save the received data.
7656 * silc_server_free_sock_user_data now notifies routers in the
7657 network about entities leaving the network.
7659 At the same time implemented functions silc_server_remove_id
7660 and silc_server_send_remove_id to receive and send REMOVE_ID
7661 packets. The packet is used to notify routers in the network
7662 about leaving entities. The ID removed will become invalid in
7665 * Added function silc_idlist_del_server into server. Removes and
7666 free's server entry from ID list.
7668 * silc_server_private_message function now checks, if we are router,
7669 that the destination ID really is valid ID, naturally.
7671 * In router when NEW_ID packet is received (for new client) the
7672 hash of the Client ID is saved in the ID Cache but the
7673 client->nickname is set to NULL, instead of putting the hash
7676 IDENTIFY command now also checks that client->nickname must be
7677 valid. If it is not if will request the data from the server who
7678 owns the client. Added new function
7679 silc_server_command_identify_check.
7681 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7682 to set the command to already allocated Command Payload.
7684 * Tested private message sending in router environment with two
7685 routers, two servers and two clients. Fixed minor bugs and now
7688 * Fixed segfault from client's NAMES command. Used to crash if
7691 * Forwarded packets must not be routed even if it is not destined
7692 to the receiver. Changed server code comply with this.
7694 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Added `require_reverse_mapping' boolean value to ServerParams
7697 structure. If TRUE (not default) the server will require that
7698 the connecting host has fully qualified domain name.
7700 If the reverse mapping is not required and hostname could not be
7701 found the IP address is used as hostname.
7703 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7705 * Implemented version string checking to both client and server.
7706 The check is incomplete currently due to the abnormal version
7707 strings used in development version of SILC.
7709 * Changed all command functions in server to use the new
7712 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Changed char *data to unsigned char *data in ID Cache system to
7715 support binary data as ID Cache data. Changed code to support
7716 binary data in lib/silccore/idcache.c.
7718 * Renamed silc_server_packet_relay_command_reply to
7719 silc_server_command_reply as it is normal packet receiving
7720 function. Rewrote the function to accept command replys for
7721 servers and not only for clients.
7723 * Mark remote router always as registered server if we are connecting
7724 to it. Otherwise, commands sent by the router to us are ignored.
7726 * All ID List find routines now returns the ID Cache Entry pointer
7727 as well if requested.
7729 * WHOIS command works now in router environment, tested with two
7730 routers, two servers and two clients.
7732 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7733 in router environment (as it is almost equivalent to WHOIS) but
7734 hasn't been tested thoroughly. Added new functions:
7736 silc_server_command_identify_parse
7737 silc_server_command_identify_send_reply
7738 silc_server_command_identify_from_client
7739 silc_server_command_identify_from_server
7741 * Disabled route cache adding because adding two different ID's with
7742 same IP replaces the old cache entry thus giving wrong route.
7743 The entry->router->connection is always the fastest route anyway
7744 so route cache may not be needed. Of course, new routes maybe
7745 established after receiving the ID when the entry->router->connection
7746 might not be anymore the most optimal.
7748 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Add route cache for received ID for fast routing.
7752 * Added silc_server_packet_route to route received packet on router
7753 that is not destined to us.
7755 * Renamed silc_server_get_route to silc_server_route_get.
7757 * Added id_string and id_string_len fields into SilcServer to
7758 include encoded ServerID for fast comparing without excess
7759 encoding of the ID's.
7761 * Cleaned up WHOIS command on server side. Added following static
7764 silc_server_command_whois_parse
7765 silc_server_command_whois_check
7766 silc_server_command_whois_send_reply
7767 silc_server_command_whois_from_client
7768 silc_server_command_whois_from_server
7770 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7771 arguments in command replies. All command functions should be
7772 updated to use this macro.
7774 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Minor typo fixes on command reply handling on server.
7778 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7780 * Added silc_server_command_add_to_channel internal routine to add
7781 the client to the channel after router has created the channel and
7782 sent command reply to the server.
7784 * Added generic silc_server_send_command to send any command from
7787 * Use static buffer with ID rendering instead of duplicating data.
7789 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7791 * Fixed a channel user mode bug when joining to a channel server gave
7792 everybody channel founder rights, oops.
7794 * We mark ourselves as the router of the incoming server connection
7795 if we are router ourselves. This way we can check in some packet
7796 sending functions whether it is locally connected server. For
7797 incoming router connections we put NULL.
7799 * For router sending packets locally means now always sending the
7800 packet cell wide; to local clients and local servers. For normal
7801 server sending packet locally means sending it to only local
7804 * Fixed the JOIN command to really work in router environment. If the
7805 channel is created it is always created by the router. Router is
7806 also responsible of making the initial joining to the channel,
7807 sending JOIN notify to the sending server and distributing
7808 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7809 does not exist server doesn't do anything else but forward the
7810 command to the router which performs everything.
7812 * Added silc_server_send_channel_key function to send the Channel Key
7815 * Added silc_server_create_channel_key to create new channel key. The
7816 channel key is now re-generated everytime someone joins or leaves
7817 a channel, as protocol dictates. Note: channel->key_len is the
7820 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7823 packet_receive.[ch] to separate packet sending and receiving
7824 routines. The server.[ch] now includes everything else including
7825 actual packet processing (writing and reading data) and other
7828 Renamed silc_server_private_message_send_internal to
7829 silc_server_send_private_message. The routine is still though
7830 used only to relay private messages as server does not send
7831 private messages itself.
7833 Renamed silc_server_new_channel to silc_server_create_new_channel
7834 and added new function sicl_server_new_channel that handles the
7835 incoming New Channel packet. Added also new sending function
7836 silc_server_send_new_channel to send New Channel Payload.
7838 * Added new function silc_server_notify to process incoming notify
7839 packet to the server/router. Server may then relay the notify
7840 to clients if needed.
7842 * Added new function silc_server_new_channel_user to process incoming
7843 New Channel User packet. Router will redistribute the packet and
7844 send JOIN notify to its local clients and locally connected servers
7845 if needed. Normal server will send JOIN notify to its local client
7846 on same channel when received this packet. Added also corresponding
7847 sending function silc_server_send_new_channel_user to sent the
7850 * Added boolean route argument to send_notif_to_channel and
7851 packet_send_to_channel functions to attempt to route the packet
7852 if it is TRUE and send only locally if it is FALSE.
7854 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * silc_server_replace_id now broadcasts the received replace ID
7857 packet if it is not broadcast packet already. The router must
7858 broadcast to inform other routers about changed ID.
7860 * Added backpointer to server's router into SilcServer context in
7861 silcd/server_internal.h.
7863 * Fixed silc_server_packet_broadcast to send correct broadcast
7866 * The channel key is now distributed to the local client as soon
7867 as it is received from the router (in router environment) so that
7868 no other packet may be sent for the channel until client has
7871 * silc_server_remove_channel_user now broadcasts the received
7872 Remove Channel User packet if it is not broadcast packet already.
7873 The router must broadcast to inform other routers about removed
7876 * Added users field into SilcPacketContext that is a reference count
7877 of the context. One can increase the reference count by calling
7878 silc_packet_context_dup which is now changed to just increase the
7879 reference count instead of duplicating the data. The reference
7880 count is decresed by calling silc_packet_context_free that will
7881 free the data after the reference count hits zero.
7883 For now on the packet context and everything allocated into it
7884 (including the raw packet from network) must be freed by calling
7885 the new silc_packet_context_free function. Added also new function
7886 silc_packet_context_alloc that must be used now to allocate the
7887 context. This also means that if a routine is asynchronous from
7888 silc_[client/server]_packet_parse_type the packet context must
7889 be duplicated by calling silc_packet_context_dup. Otherwise it
7890 gets free'd after silc_[client/server]_packet_parse_type returns.
7891 Also, one must remember that if packet is duplicated then its
7892 reference count must be decresed by calling the free function as
7893 many times as it was duplicated.
7895 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7896 from both client and server.
7898 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7900 * Made joining to a channel working in router environment.
7902 * Cleaned up JOIN command on server side and create function
7903 silc_server_command_join_channel internal routine to make the
7906 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7908 * Changed silc_command_pending list to SilcDList. Also, added
7909 `ident' field to SilcServerCommandPending structure to identify
7910 the reply and to call correct callback.
7912 Added silc_server_command_pending_check function to replace the
7913 corresnponding macro. The silc_command_pending list is not
7916 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7917 to set identifier to previously allocated Command Payload. It
7918 is used to set identifier for command when resending Command
7921 * Added silc_command_payload_encode_payload to encode Command
7922 Payload buffer from SilcCommandPayload structure.
7924 * Added silc_argument_payload_encode_payload to encode Argument
7925 payload buffer from SilcArgumentPayload structure.
7927 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Changed WHOIS command to support router connection on server side.
7930 The whois request is always sent to router unless the server is
7931 standalone server. After server has received the reply from the
7932 router will it send the reply to the client.
7934 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7935 broadcast received broadcast packet. The function is used only
7936 by router. The broadcast packet is always sent to the router's
7939 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7940 render given ID to printable string, for log files for example.
7942 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Made basic router to router connections working. At least they
7945 can now connect to each other but nothing really works the way
7946 they are supposed - yet.
7948 * Added new initiator token to RouterConnection configuration
7949 file in silcd/serverconfig.[ch]. It is used to tell whether we
7950 are the initiator to the remote router or whether we'll expect
7951 the other end to connect.
7953 * Moved registering of listener task to silc_server_init, hence
7954 the server starts listenning as soon as it is run, even if it
7955 does not have connections to other routers. Let's see how well
7958 * Changed default connection retry timeouts for more suitable in
7961 * Removed cipher and such arguments from silc_idlist_add_client
7962 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7963 Added new function silc_idlist_add_data to add the keys and stuff
7966 * Added SilcIDListData structure and added it to SilcClientEntry
7967 and SilcServerEntry as their first field in the structure. This
7968 way we can explicitly cast the ID entries to the SilcIDListData
7969 structure and get common data for the entries. In past, we had
7970 to first check what type of connection it is and then cast it to
7971 correct ID entry type. Now, we can directly cast the opaque
7972 pointer to the SilcIDListData (no matter what ID entry it actually
7973 is) and get the data needed.
7975 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7978 in some circumstances even if threre were timeout tasks, though not
7979 IO tasks, but tasks anyway. Now fixed.
7981 * Defined SilcServerConnection structure to hold connection specific
7982 stuff about directly connected servers and routers. The definition
7983 is currently in silcd/server_internal.h. I thought about having
7984 a bit more important role fro this struct but for now it is used
7985 only when connecting to other server (or router actually).
7987 * Added connecting retry support in server when connecting to
7988 router(s). The retry feature implement exponential backoff
7989 algorithm. Also, added SilcServerParams structure to hold default
7990 parameters for server. For now, it include these retry settings
7991 and are hard coded. After server is moded to be as Silc Server
7992 Library this structure will be more important.
7994 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * Changed client librarys channel->clients table to SilcList and
7997 changed code accordingly.
7999 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8001 * Changed client's channel table to SilcList and changed code
8002 accordingly. Also changed SilcChannelClientEntry to include back-
8003 pointer to the channel so that client entry can use that structure
8004 as list as well and we have fast cross-reference to the channel.
8005 This change dramatically decreased the complexity of channel
8006 handling with client entry and vice versa (removed one extra
8007 loop when searching for channel entry from many functions).
8009 * Changed server->sim from table to SilcDList and changed code
8012 * NAMES command can now be used from user interface. It will show
8013 the user list on the channel, neatly.
8015 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8016 Code now saves realname of the user if it becomes available.
8018 * Renamed configure.in to configure.in.pre and made ./prepare
8019 script to automatically add correct version string to
8020 configure.in which it creates from configure.in.pre.
8022 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8024 * NAMES command reply now shows users mode with the nickname when
8027 * Moved silc_client_ch[u]mode[_char] functions from
8028 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8029 place sucks, they are utility functions and should be in some
8032 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8034 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8037 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Added TRQ (efficient deque and list library) into lib/trq. This is
8042 a very good list library that is currently used in the SILC. Defined
8043 SilcList API over the library because I didn't like the API very
8044 much. See lib/trq/silclist.h for the API and examples of how to
8045 use the API. Fixed various places in the code to use the new
8046 SilcList API. The SilcList is meant for lists that has a structure
8047 already defined as a list. It is not suitable to add just some
8048 context to the list (in TRQ, the context is the list actually).
8050 So, I defined SilcDList that can be used for the purpose where
8051 predefined list structure does not exit. This can be used as
8052 such list. Now some context just can be added to the SilcDList.
8053 Currently this list is not used in the SILC just yet, though there
8054 are a lot places where this can replace dynamically allocated
8055 tables and I will fix these places, later, to use SilcDList.
8056 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8057 and use TRQ internally).
8059 Also fixed some annoying warning messages that the original TRQ
8060 code generated. Also minor changes to TRQ's Makefile.in.
8062 * Added support for querying by Client ID to both WHOIS and
8063 IDENTIFY commands into server, as required by the protocol.
8065 * Removed method function pointers from SilcBuffer structure. They
8066 weren't used to anything and just increased the context size for
8067 no good reason. This change also made silc_buffer_alloc and
8068 silc_buffer_free functions inline functions.
8070 * Disabled command flooding detection support until it's fixed so
8071 that it accepts commands in but does not execute them more than once
8074 * Added silc_net_localhost(), to return local hostname, into
8075 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8076 that must be initialized before calling silc_client_init.
8078 * Added new function: silc_server_send_notify_on_channels to send
8079 notify messages to all channels client has joined. It is assured
8080 that the message is sent only once per client.
8082 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8083 lib/silcutil/silcutil.[ch] as silc_format function. The new
8084 function is generic and is used by server as well, not only by
8085 the logging routines.
8087 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8088 the provided version string was not acceptable. Added new function:
8089 silc_ske_check_version into lib/silcske/silcske.h. The function
8090 must be implemented by the application (client or server) and it
8091 does not reside in the SKE library. The function checks the version
8092 string remote end sent.
8094 * Added back pointers (to opaque context and to SilcSocketConnection)
8095 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8097 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8098 duplicate packet context structure.
8100 * Changed `notify' client operation to send same arguments as client
8101 receives from server except for ID's. ID's are mapped to correct
8102 ID entry and that is returned. Also, if channel entry is not sent
8103 by server but the notify is for channel the channel entry is sent
8104 to application (otherwise application doesn't know that it is for
8105 channel (library gets it from packet's Destination ID)).
8107 * Added silc_client_remove_from_channels into client library to
8108 remove a client from all channels it has joined to. Used when
8109 received SIGNOFF notify from server. Added also new function
8110 silc_client_replace_from_channels to replace old ID entry with
8111 new ID entry on all channels. Used when received NICK_CHANGE
8114 * Fixed ID Cache list handling in silc_idlist_get_client in
8115 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8116 to get (or query) client by ID.
8118 * Updated TODO list.
8120 * Added connection authentication status message defined by the
8121 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8122 support for these into the code in client and server side.
8124 * Added generic function silc_client_send_command to send any command
8125 with variable argument list. Application should use this function
8126 to send commands if the command functions provided by the library
8127 does not suite for the application's user interface needs.
8129 * Added new `failure' client operation. Application is notified about
8130 received failure packet if client is executing a protocol. In this
8131 case the protocol's execution has failed.
8133 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8134 is required by the protocol.
8136 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8137 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8140 * Added status flag to SilcSKE object to indicate realtime status
8141 of the SKE protocol.
8143 * Application receives now exactly same command reply arguments as
8144 the library receives from server. However, if ID is received the
8145 corresponding ID entry is returned to the application (eg. Client
8146 ID is mapped to correct SilcClientEntry entry and that is returned).
8147 Changed command_reply client operation due to this change.
8149 * Changed all ID's in commands and in command replys as ID Payloads.
8150 Change affected both client and server side codes.
8152 All ID's sent in SILC network (with execption of ID's in SILC
8153 Packet header) are sent in ID Payload to support variable length
8156 * Server now notifies nick changes and notifies all clients on
8157 the channels about the new nickname (about the new Client ID,
8160 * Implemented CMODE command to change channel modes. Supports all
8161 channel modes defined by the protocol specs except ban and invite
8162 lists. (Also, private channel key mode is supported but support for
8163 setting private channel key in client is missing, thus, this mode
8164 has no effect on client side (except that server requires that the
8165 client uses private channel key and normal channel traffic does not
8168 Also, invite mode works per se, but INVITE command does not work
8169 yet correctly, so you can set channel as invite only channel but
8170 inviting clients to the channel does not work (it is yet to be
8171 thought what's the best way to do it).
8173 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8174 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8175 Implemented CUMODE command to change user's mode on the channel.
8176 Supports all modes defined by the protocol specs.
8178 * Added NAMES command reply to return users modes on the channel.
8180 * Removed unnecessary and slow ciphers from lib/silccrypt.
8182 * Set SO_KEEPALIVE option to connection sockets by default.
8184 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8186 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8187 redefined the Notify Payload into protocol specs.
8189 * Added silc_id_payload_parse_id to get ID directly from raw
8192 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8194 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8195 accept searching by Client ID as well.
8197 * Added support for LEAVE and SIGNOFF notify types in client library.
8199 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8200 to parse ID Payload from raw data.
8202 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added flags parameter into silc_ske_assemble_security_properties
8205 function in lib/silcske/silcske.[ch].
8207 * Changed notify client operation to fit better for notify messages
8208 sent by server. The notify payload received from server is now
8209 passed to the application (after parsing it to SilcNotifyPayload).
8210 It is application's responsibility to retrieve the arguments
8211 from the payload and show the message the way it wants. The message
8212 sent by server is implementation specific.
8214 * Changed public keys to comply with the protocol specification.
8215 Old public keys are not supported anymore and are not compatible.
8217 * Removed nickname from Channel Payload as the latest draft removed
8218 it. The client must resolve the nickname from the NAMES command
8219 reply received when it joined the channel.
8221 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8223 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8225 * Fixed some errors in protocol specification drafts.
8227 * Created lib/silccore/silcnotify.c to implement Notify Payload
8228 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8229 generic payloads described by protocol specifications. The file
8230 includes implementations for ID Payload and Argument Payload.
8232 * Changed Command Payload implementation to use the new Argument
8233 Payload. Changed command_xxxx_payload to command_payload_xxxx
8234 to comply with SILC coding conventions.
8236 * Added suppport for Argument Payload handling in Notify Payload
8237 implementation as protocol requires it. Added the new support
8238 into server and client lib as well.
8240 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8242 * Added support for multiple nicknames on same channel. [n] is
8243 added locally to the nickname if there are more than one same
8244 nicknames on the channel.
8246 * Server now sends all nicknames that matched WHOIS request.
8247 Client also shows the list received from server.
8249 * Added TOPIC command to client side. User can now set and show
8250 current topic on channel.
8252 * Added MOTD command to client and server. Also, server sends the
8253 motd when client connects to the server.
8255 * Changed version strings to comply ISO 8601.
8257 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8259 * Fixed protocol error handling in client library. It should now
8260 cope even if the SKE fails for some reason.
8262 * Made new protocol specification drafts for submitting to IETF.
8264 * Implemented TOPIC command to server in silcd/command.c.
8266 * Added two new notify types into lib/silccore/silcnotify.h:
8267 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8268 notify nickname change and topic setting/change on a channel.
8270 * API change of command_reply operation in client library. The
8271 application gets now the status type received from server as well.
8273 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8275 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8277 * Cras fixed and optimized the packet handling even further and
8278 it should work now. Minor change to the prototype of function
8279 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8281 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8283 * Added new function into lib/silcutil/silcschedule.[ch]:
8284 silc_schedule_with_fd to select() a specified fd. The function
8285 returns after timeout expires or data arrives or goes. The
8286 function is used by packet routines to wait that all data is
8287 received from network.
8289 * Fixed data reading from network in lib/silccore/silcpacket.c.
8290 The code now assures that all data is read from the fd and then
8291 continues packet processing. This was a bug fix since the code
8292 used to drop some data in some circumstances.
8294 * Added new function into lib/silcclient/client.[ch]:
8295 silc_client_start_key_exchange to start key exchange after
8296 connection has been established to server. The code internally
8297 now uses this funtion but its main purpose was to provide it
8298 for applications that perform their own connecting. After
8299 application has created a connection it merely calls this
8300 function to start the key exchange between client and server.
8301 The library takes care of everything else after that.
8303 Updated also lib/silcclient/README to explain the usage of
8306 * Do not send to application information that connection has
8307 been established. Application gets notified it by connect
8310 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8312 * Applied cras's patch to add silc_schedule_one function. The
8313 function runs scheduler once and returns.
8315 * Fixed the scheduler after cras messed it up. The timeout
8316 handling works now as it's supposed to work.
8318 * Added into lib/silccore/ silcnotify.h to include notify
8319 message types support. Changed silc_server_send_notify*
8320 functions, in server.[ch], to support those new notify types.
8321 Added the support for the notify types into client library,
8322 as well. Added new notify client operation into ops.h in
8325 * Changed silc_server_packet_send_to_channel to send normal
8326 packets instead of just channel message packets. The function
8327 is now used to send the notify packets to channels. It is not
8328 used to send channel message packets anymore, as server never
8331 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8332 va_arg()s as it seems to require it nowadays. I guess, if SILC
8333 is compiled with older va_arg() the new code should work anyway.
8335 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8337 * Splitted core library. Core library (lib/silccore) includes
8338 now only SILC protocol specific core (and common) components.
8339 Created new utility library (lib/silcutil) that includes more
8340 generic purpose stuff. The stuff for util library was taken
8341 from the old core library. This was minor and easy split.
8343 * Created SILC Client Library (lib/silcclient) that includes
8344 implementation of the SILC client without user interface. This
8345 was major move from silc/ directory. The code has been changed
8346 so that it is transparent towards the user interface. The
8347 silc/ directory includes now the same user interface as before
8348 and it uses the new client library. Read lib/silcclient/README.
8349 Basicly, the client library performs everything else related
8350 to SILC except user interface handling. Also, configuration
8351 files are considered to be part of user interface and library
8352 does not handle them.
8354 This change also changed a lot of structures, function naming etc.
8355 Most important change was that SilcClientWindow object was
8356 renamed to SilcClientConnection in the client library. Created
8357 also new file lib/silcclient/ops.h. Also added new files
8358 silc/local_command.[ch] and silc/client_ops.[ch].
8360 All these changes were made to make it easier for user interface
8361 designers to create what ever user interface for the SILC client
8364 It is also expected that the server will be moved to lib
8365 directory as well and SILC Server Library will be created;
8366 sometimes in the future.
8368 * Removed Local commands from lib/silccore/silccommand.h as
8369 they are application specific and new client library does not
8370 handle any of those anymore.
8372 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8373 old client implementation in silc/.
8375 * Added support for callback functions in SILC_LOG_* macros.
8376 Application can now set its own callbacks that will be called
8377 instead of using the default functions that will always print
8378 the debug messages to stderr (or stdout). Also, debugging can
8379 now be disabled by setting silc_debug to FALSE and re-enabled by
8380 setting it to TRUE. Note, that logging will still work even
8381 if debugging is disabled.
8383 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8384 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8385 silc_log_reset_debug_callbacks.
8387 * To enable debugging in silc client one must give now -d
8388 option on command line.
8390 * Changed silc_schedule_init to automatically allocate task queues
8391 if they are not allocated before calling it.
8393 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8395 * Added GMP 3.1 into math library.
8397 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8400 a channel in SILC network. The packet is used by servers and
8401 routers to notify other routers that user has left a channel.
8402 This little feature was missing until now. Added the feature
8403 to protocol specification as well.
8405 Added functions: silc_server_send_remove_channel_user and
8406 silc_server_remove_channel_user into server.[ch].
8408 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8409 lib/silccore/silcpacket.h. However, they are not implemented
8412 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8414 * Fixed joining to a channel and sending channel messages
8415 between server and router. The channel message sending should
8416 now work inside a cell.
8418 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Fixed the private message sending between server and router.
8421 The private message sending should now work inside a cell.
8423 * Added silc_server_replace_id into server.[ch] to replace
8424 existing ID in the SILC network.
8426 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8427 and silc_idlist_replace_server_id into idlist.[ch] in server.
8429 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8431 * Fixed the server to server connections. Server can again now
8432 connect to router. Router to router connections probably does
8435 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Added dynamic protocol registering support. Now protocols can
8438 registered and unregistered on the fly. Patch by cras.
8440 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8442 * Added lib/contrib directory to hold routines that some platforms
8443 don't have but are needed by SILC.
8445 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8446 into lin/contrib to provide getopt() and getopt_long() for
8447 those who don't have it.
8449 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8451 * Added AWAY command to client. When away message is set and
8452 client receives a private message packet the client automatically
8453 replies to the sender with the away message.
8455 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8456 bug seemed to be the cause of recent problems when compiling
8459 * Added version detection support to SKE protocol specification
8460 and added the new changes to the SKE implementation as well.
8461 There were other minor changes in the SKE protocol as well.
8463 Many changes in lib/silcske/silcske.[ch] and in
8464 lib/silcske/payload.[ch].
8466 * Added ^U functionality, clear input line. Patch from cras.
8468 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8470 * Mainly small bugfixes on core library. Fixed some debugging
8471 logging and buffer overflow in silclog.c.
8473 * Updated config.sub and config.guess on the distribution tree.
8475 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8477 * Added command lagging support in server. Client may execute
8478 commands now only once in two seconds.
8480 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8482 * Optimized packet reception. MAC computation and checking is now
8483 also more optimized. A lot previously duplicated code is now
8484 used as generic by both client and server.
8486 * Fixed key pair generation in clientutil.c
8488 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8490 * Added into lib/silccore/silcbufutil.[ch] new function;
8491 silc_buffer_realloc.
8493 * Moved generic packet sending/encryption functions to
8494 lib/silccore/silcpacket.[ch] from client and server. Some
8495 rewriting of the functions.
8497 * Moved all generic packet reception/decryption functions to
8498 lib/silccore/silcpacket.[ch] from client and server. The
8499 packet processing is now much cleaner in both client and server.
8500 These were major changes in both client and server.
8502 * Created many common functions in server to do packet sending.
8503 Previously code were duplicated a lot, this has been removed
8506 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8508 * Rewrote major parts of the ID cache system. Don't know
8509 whether it is better now or not but at least the API is more
8512 * Major rewrite on ID cache stuff on client because of the ID
8513 cache API changes. Added idlist.c to client.
8515 * Also major rewrite on ID cache stuff on server as well.
8516 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8517 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8518 in hand, instead they are all put into the ID cache system now.
8519 All server_idlist_* routines uses ID cache now instead of
8520 traversing its own lists (those lists does not exist anymore).
8521 SilcIDList though still exists. Also, SilcXXXEntry's are
8524 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8526 * Finally made the SKE implementation compliant to the protocol
8527 specification. All mp integers are now binary encoded as
8528 opposed being HEX encoded.
8530 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8533 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8534 functions: silc_[encode/decode]_pem. Also added function
8535 silc_encode_pem_file to PEM encode with newlines ('\n') for
8538 * SILC public keys are now encoded either PEM or binary. Same
8539 option is for private keys as well. By default private keys
8540 are binary encoded and public keys PEM encoded. Silly HEX
8541 encoding were removed.
8543 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8544 function to create fingerprints.
8546 * Fixed a bug in SHA1; does not change the original data anymore.
8548 * Partly implemented INFO command on client and server side.
8549 Fixed CLEAR command. Changes to SERVER command; show current
8550 server(s) when giving command without arguments. Added
8551 VERSION command to client.
8553 * Added check to server that unregistered connections cannot
8554 execute commands (unless it is specificly allowed).
8556 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8558 * Fixed screen refresh.
8560 * Fixed channel joining bug from client. On some circumstances
8561 client tried to join to a channel it had already joined.
8563 * Added public key verification process into client's protocol.c.
8564 The client now verifies the public key from user and saves
8565 it into ~./silc/serverkeys/ directory.
8567 Added into: clientutil.[ch]: silc_client_verify_server_key.
8569 * Changed SKE protocol's silc_ske_initiator_finish function
8570 to accept callback function that verifies the received public
8571 key. Removed old silc_ske_verify_public_key function.
8573 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8575 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8576 silc_pkcs_private_key[_data]_set.
8578 * Made the password and public authentication more cleaner in
8579 server's protocol.c.
8581 * Removed historic and obsolete protocol `channel_auth' from
8582 both client and server.
8584 * Removed wrong way of sending command status messages from
8585 server to client in server's command.c. The old way violated
8586 protocol specification.
8588 Changes to silccore/silccommand.[ch]: removed
8589 silc_command_encode_status_payload -> not needed anymore,
8590 changed silc_command_encode_payload_va to accept extra
8591 argument on variable argument list. The argument type must
8592 now be provided to the function. Also, added new function:
8593 silc_command_encode_reply_payload_va which is same as
8594 normal command_encode_payload_va except command status type
8595 is provided as extra argument.
8597 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8599 * Added ~./silc directory handling. The directory includes the
8600 public and private keys for the client.
8602 Added silc_client_check_silc_dir, silc_client_create_identifier
8603 and silc_client_load_keys.
8605 * Implemented SILC protocol compliant public key. Added public
8606 and private key saving to and loading from files.
8608 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8609 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8610 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8611 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8612 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8614 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8615 silc_pkcs_load_[public/private]_key.
8617 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8619 * Added silc_server_get_route (route.[ch]) to get connection
8620 data for the fastest route for given ID.
8622 * Implemented INVITE command on client and server. The command
8623 were re-defined in the SILC Protocol Specification and the
8624 implementation now complies with the specification.
8626 * Implemented PING command on client and server.
8628 * Implemented NAMES command on client and server. The server side
8629 supports currently only normal server not router server yet.
8630 Some changes to NAMES definition in SILC protocol specification.
8632 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8634 * Implemented LEAVE command on client and server.
8636 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8637 again. This change was made to the protocol as well. Server
8638 should not violate the protocol specification anymore.
8640 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8642 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8643 was tested. SOCKS4 was not but should work anyway.
