528 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
530 * Added new channel user mode BLOCK_MESSAGES which the client
531 may set to itself to tell server not send channel messages.
532 Other packets such as channel key packets are still sent.
533 Protocol TODO #23. Updated the protocol specs, client and
534 server. Affected files are lib/silccore/silcmode.h,
535 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
536 lib/silcutil/silcutil.c, silcd/command.c, and
539 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Redefined the Status Payload to include now two 8 bit fields,
542 instead of one 16 bit field. This now makes it possible to
543 send list of errors. Updated the protocol specs and the code
544 in core library, client library and server. Protocol TODO #1.
545 Affected files are lib/silccore/silccommand.[ch],
546 lib/silcclient/command_reply.[ch], silcd/command.c,
547 silcd/command_reply.c and silcd/packet_receive.[ch].
549 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
551 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
552 must be handled by the application and should tell the application
553 that an error message was already printed, and it should print the
554 config coords (line, filename, ...). Affected files are
555 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
557 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
558 server config parsing code more readable.
560 Fixed a bug in the fetch_logging() config callback.
562 Affected files is silcd/serverconfig.c.
564 * Drop root privileges when started in foreground. Don't drop them
565 if debugging also. Affected file is silcd/silcd.c.
567 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Added more IM-like features by introducing new user modes
570 for setting various presence information. Added new modes:
571 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
572 specs and code. Protocol TODO #19. Affected files are
573 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
574 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
576 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
578 * Added STATS command to the protocol after all, to return
579 various statistical information about the network. It can
580 be used by clients to retrieve statistical information, and
581 servers may use it to to fetch cell and network wide
582 statistics from router. Updated the protocol specs and
583 implemented it to the server. Protocol TODO #16.
584 Affected files are lib/silccore/silccommand, silcd/command.[ch],
585 silcd/command_reply.[ch].
587 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
589 * The LIST command reply in client libary now adds new channel
590 entry if the returned channel doesn't exist yet in cache,
591 and returns the channel entry to the application in the
592 command_reply client operation. Affected file is
593 lib/silcclient/command_reply.c.
595 * Changed the channel message payload's MAC generation to
596 include the IV in the MAC as well. This way all relevant
597 parts of the channel message payload are authenticated also
598 with the channel message MAC (and not only by packet MAC).
599 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
600 Affected file is lib/silccore/silcchannel.c.
602 * Fixed the SKE to save the remote version, since the
603 silc_ske_parse_version mistakenly checked wrong version,
604 after it replaced the start payload. Affected files are
605 lib/silcske/silcske.[ch].
607 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
609 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

611 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
612 Affected files lib/silcutil/silcstrutil.[ch].
614 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
615 files are lib/silcutil/silcstrutil.[ch].
617 * Defined that the security property fields in SKE SHOULD be
618 UTF-8 encoded, defined that version string MUST be US-ASCII
619 encoded, defined that passphrases sent in connection
620 authentication protocol MUST be UTF-8 encoded. Implemented
621 these to the client and server. Defined also that other
622 passphrases sent in the protocol MUST be UTF-8 encoded.
623 Affected files are lib/silcske/silcske.c,
624 lib/silcclient/protocol.c, silcd/protocol.c,
625 silcd/serverconfig.c, and lib/silccore/silcauth.c.
627 * Changed the silc_client_close_connection interface to not
628 need the SilcSocketConnection which should not be visible
629 to application. Affected files are lib/silcclient/client.c
630 and lib/silcclient/silcclient.h.
632 * Rewrote the text for Private Message Key Payload in the
633 protocol specification. Protocol TODO #11.
635 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Upgraded the protocol version to 1.1, updated protocol specs
640 * Added the nickname as new argument to NICK_CHANGE notify and

648 Protocol TODO #13. Affected files are silcd/command.c,
649 silcd/packet_receive.c, packet_send.[ch],
650 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
651 The killer's client entry is now returned to application in
652 the `notify' client operation.
654 * Fixed the Max Argument fields that had too large value set
655 in the protocol specs. Protocol TODO #14.
657 * Added the LEAVE command reply to return the ID of parted
658 channel. Updated protocol specs and implemented it to the
659 client and server. Protocol TODO #15. Affected files are
660 silcd/command.c, lib/silcclient/command_reply.c. The channel
661 entry is now returned to application in the `command_reply'
664 * Rewrote the version SKE version checking in client libary
665 and in server to use the silc_parse_version_string. Affected
666 files are lib/silcclient/protocol.c, silcd/protocol.c.
668 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
669 commands that was missing it, and updated protocol specs and
670 the server implementation. Protocol TODO #10. The affected
671 file is silcd/command.c.
673 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
674 generic reply to a generic request (REQUEST flag), and
675 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
676 way. A draft-riikonen-silc-flags-payloads-00.txt is written
677 to define the payload for DATA flag. Added the flags to
678 the implementation. Protocol TODO #9. Affected file is
679 lib/silccore/silcchannel.h.
681 Changed the client library to return the message length
682 to application as well in the channel_message and private_message
683 client operations. Affected files are
684 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
685 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
686 and lib/silcclient/client_ops_example.c.
688 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
689 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
690 the channel. Updated protocol specs and impelemented this
691 to client and server. Protocol TODO #6. Affected files are
692 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
693 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
695 Added new options m and M to CMODE command in Irssi SILC
696 client to set these modes.
698 * Deprecated all administrative commands from SILC protocol
699 since they are highly implementation specific commands.
700 Updated protocol specs. Moved the old commands in
701 implementations to private range of command types. Affected
702 files are silcd/command.c, lib/silcclient/command.c and
703 lib/silcclient/command_reply.c. Protocol TODO #8.
705 * Fixed a bug in server where sending unknown command crashes
706 the server. Affected file silcd/command.c.
708 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
710 * Added SILC_PROTOCOLVERSION macro to check protocol version
711 of a socket connection. The affected file is
712 lib/silcutil/silcsockconn.h.
714 * Added better error logging in rekey protocol. Affected file
717 * Do not check public key types in SKE during rekey. Affected
718 file lib/silcske/payload.c.
720 * Fixed the rekey protocol with PFS, which was totally broken.
721 Affected file silcd/protocol.c.
723 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Some client implementations quit network by doing first LEAVE
726 and then immediately SIGNOFF (like Bombyx). We now do check
727 after a short time after LEAVE notify and check whether the
728 client is still valid after LEAVE, and if not we remove it from
729 cache. Affected file is lib/silcclient/client_notify.c.
731 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
733 * Merged version 1.1.4 of zlib. Even if it not currently in use,
734 it's good not to have security holes here.
736 * Fixed a negative refcount situtuation for the config context.
737 Affected file is silcd/serverconfig.c.
739 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
741 * ROBOdoc documented lib/silcutil/silcutil.h.
743 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Optimized even more the SilcPacketContext structure. Now
746 totally saved 16 bytes of memory per context after optimization.
747 Affected files are lib/silccore/silcpacket.[ch].
749 * Made strict checks for valid SILC IDs. Affected file is
750 lib/silccore/silcid.c.
752 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Changed the object argument for silc_cipher_register,
755 silc_hash_register, silc_hmac_register and silc_pkcs_register
756 to const. Affected files are lib/silccrypt/silccipher.[ch],
757 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
759 * Changed the silc_get_username and silc_get_real_name to
760 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
762 * Fixed the Irssi SILC Client to use the silc_get_username and
763 silc_get_real_name insted of glib routines since the glib
764 routines only corrupt stack. Fixes the Irssi SILC to work in
765 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
767 * Fixed the Irssi to not use g_get_home_dir since it crashes
768 or returns garbage on cygwin and corrupts stack. Added function
769 get_home_dir to Irssi routines. Affected files are
770 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
772 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Made some structure optimizations. SFTP memory FS MemFSEntry
775 entry structure. Optimized SilcTask structure. Optimized
776 SilcPacketContext structure.
778 Affected files lib/silcsftp/sftp_fs_memory.c,
779 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
781 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
783 * And yet again reverted back the config thing since Johnny
784 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
787 * Fixed memory leaks from config object. Affected files are
788 silcd/serverconfig.[ch].
790 * Added support for adding new connections to the server in rehash.
791 After rehash they take effect.
793 Added support for changing the maximum allowed connections in
794 rehash. The number can grow but going smaller is not supported.
796 Added function silc_server_num_sockets_by_remote to the
797 silcd/server_util.[ch].
799 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
801 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
803 * Added preliminary checking during config parsing for a valid
804 public/private key and removed further checks in the code.
805 Affected files are silcd/serverconfig.[ch], server.c.
807 * Moved functions silc_server_drop() and silc_server_daemonise()
808 from server.c to silcd.c since they are stricly related to
809 the application activity.
811 * Reverted a small part of the automatic ref/unref since
812 it caused a double unref in some situations. Affected
813 files are silcd/silcd.[ch], server.c, serverconfig.c.
815 * Added some .cvsignore files in the lib directory.
817 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed silc_net_gethostbyaddr to correctly resolve by
820 address. Affected file lib/silcutil/silcnet.c.
822 * Fixed the notify relaying to client. The HMAC to be used
823 with relayed packets ws wrong and caused decryption failure
824 at the client end. Affected file is silcd/packet_receive.c.
826 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Created new branch silc_protocol_1_0_branch.
830 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
832 * Changed the silc_server_config_* routines to be SilcServer
833 independent. They are now officially application specific code
834 and not part of generic server implementation. Affected files
835 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
837 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
839 * Added automatic referencing of config context in the
840 silc_server_config_alloc, and automatic unreferencing in the
841 silc_server_config_destroy. Affected files are
842 silcd/serverconfig.[ch], silcd/silcd.c.
844 * Fixed the silc_log_quick handling in the logging routines.
845 It didn't log quickly when it was TRUE. Affected file is
846 lib/silcutil/silclog.c. Also the flush delay was set even
847 if it was 0 in config file. Affected file is
848 silcd/serverconfig.c.
850 * Added support for changing key pair of the server in rehash.
851 Affected file silcd/server.c.
853 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Fixed the TOPIC_SET notify to not cras. It changed the topic
856 too early, before getting the channel entry. Affected file
857 is silcd/packet_receive.c.
859 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
861 * Added functions silc_server_config_[ref/unref], these are used
862 to prevent that the config object is destroyed.
864 No longer directly affect global variables silc_log_quick and
865 silc_log_delay, they are first cached inside the config object
866 and then applied with silc_server_config_setlogfiles().
868 silc_server_config_set_defaults() is now internal to
869 serverconfig.c, there are no reasons to show this internal stuff
872 Affected files are silcd/serverconfig.[ch].
874 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
875 fprintf's to stderr, since some code may be executed again after
876 the server went into the background. Affected files are
879 * Added rehash support. Added function silc_server_rehash() that
880 will perform all the basic tasks of the rehashing procedure.
882 * Added command line option `-x, --hexdump'. This will enable the
883 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
884 The option `--hexdump' implies `--debug'.
886 * Fixed a bad bug in the logging APIs (silcutil library) where
887 the application would crash after calling silc_log_reset_all().
889 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Fixed the KICKED notify handling in client library to
892 correctly remove the channel and all entries from the
893 channel when I was kicked. This bug crashed the client.
895 Fixed yet another but in KICKED notify handling to remove
896 the kicked client correctly from the channel.
898 Affected file is lib/silcclient/client_notify.c.
900 * Fixed a minor bug in looking up correct client entry
901 in KICKED notify in server. Affected file is
902 silcd/packet_receive.c.
904 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
905 sources correctly to distribution. Fixes --with-gmp option.
907 * Removed the manual rehashing from ID Cache, and changed it
908 to use the SILC Hash Table's auto rehash feature. Affected
909 file is lib/silccore/silcidcache.c.
911 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Fixed a bug in the silc_client_nickname_format function that
914 handles the multiple same nickname formatting. Two clients
915 with same nickname caused problems after the first one left
916 and rejoined. It didn't format the nickname correctly.
917 Affected file is lib/silcclient/idlist.c.
919 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
921 * Don't change the topic if olod topic is same as new one.
922 Affected file is silcd/packet_receive.c.
924 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Added cross-reference support to the SILC Documentation
927 generator. All types across all HTML files are now cross-
928 referenced. Affected files util/robodoc/generator.c and
929 scripts/silcdoc/silcdoc.
931 * Added file lib/silcutil/silctypes.h to include all the
932 arithmetic type definitions and some macros. Removed
933 includes/bitmove.h and moved macros to silctypes.h.
935 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
939 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Added `type' argument to silc_id_payload_parse_id function which
942 now returns the type of the ID to the sent pointer. Affected
943 file is lib/silccore/silcid.[ch].
945 * Added check for CMODE_CHANGE notify type that mode change is
946 allowed by the sender. Affected file silcd/packet_receive.c.
948 * Added check for CUMODE_CHANGE notify type that mode change is
949 allowed by the sender. Affected file silcd/packet_receive.c.
950 Added the ID type as CUMODE_CHANGE notify type as argument
951 to the `notify' client operation. Affected files are
952 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
954 * Added function silc_client_add_server to the client library.
955 Added support for resolving also channel and server info when
956 received unknown entity in notify packet. Affected files are
957 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
959 * Added function silc_command_get_status to return the command
960 status from the command reply's argument payload. Affected files
961 are lib/silccore/silccommand.[ch].
963 * Added check for KICKED notify type that the kicking is
964 allowed by the client. Affected file silcd/packet_receive.c.
966 * Created function silc_get_input which can be used to get input
967 (echo on or off) from user on command line. Affected files are
968 lib/silcutil/silcutil.[ch].
970 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
972 * Optimized silc_server_packet_relay_to_channel function.
973 Added new function silc_channel_message_payload_encrypt which
974 can be called directly if channel message payload needs to
975 be encrypted and is already encoded (no need to call _encode
976 function). Packet relaying is now done by router without any
977 extra memory allocations. Affected files are
978 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
981 * Fixed the INVITE notify handling. It took wrong arguments
982 as invite list and invite delete. Affected file is
983 silcd/packet_receive.c.
985 * Added check for TOPIC_SET notify type that the topic change is
986 allowed by the client. Affected file silcd/packet_receive.c.

993 silc_server_check_cmode_rights to server_util.[ch].
994 Affected files are silcd/server_util.[ch], silcd/command.c.
996 * Added function silc_server_check_umode_rights to check whether
997 changing client's user mode is allowed. Added check for
998 UMODE_CHANGE notify type that the umode change is allowed
999 by the client. Affected files are silcd/server_util.[ch],
1000 silcd/packet_receive.c and silcd/command.c.
1002 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1004 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1005 ID length. It ignored that ID can be IPv6 based as well.
1006 Affected file lib/silccore/silcpacket.h.
1008 * Fixed the silc_id_id2str and silc_id_str2id to take the
1009 IPv6 address offset's into consideration. Affecte file is
1010 lib/silccore/silcid.c.
1012 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1014 * Fixed the internal Unix scheduler functions to check for
1015 NULL context they may receive. The affected file is
1016 lib/silcutil/unix/silcunixschedule.c.
1018 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1020 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1021 can specify different directory with --home command line
1022 parameter. Affected files irssi/src/silc/core/client_ops.c,
1025 * SILC-specific commands aren't now executed if the active server
1026 isn't of SILC-type, so there won't be problems with having
1027 IRC and SILC protocol support in same client. Affected files
1028 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1031 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1033 * Improved the signal support in SILC Schedule. Added new
1034 function silc_schedule_signal_call which is used by application
1035 to mark a signal to be called. It is now safe to perform
1036 any kind of tasks in signal callbacks since it is guaranteed
1037 that the application specified signal callback is called
1038 after the signal is over. Affected files are
1039 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1041 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1043 * Added `name' field to SilcChannelPrivateKey to represent
1044 application given name for the key. Moved also the context from
1045 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1046 Added the `name' argument also to the function
1047 silc_client_add_channel_private_key.
1049 Added function silc_client_current_channel_private_key to set the
1050 current channel private key in use.
1052 Added "change" command to KEY command which can be used to change
1053 the current channel private key. Bound the command also to
1054 alt+K (Alt+Shift+k).
1056 Also affected files lib/silcclient/client_channel.c,
1057 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1059 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1061 * Added silc_rng_get_byte_fast function in to the
1062 lib/silccrypt/silcrng.[ch].
1064 * Changed the interface of silc_packet_assemble and the
1065 silc_packet_send_prepare. If silc_packet_assmble is now
1066 called the application does not call silc_packet_send_prepare
1067 because the library will call it automatically. These
1068 interfaces now also return a reference to the outgoing buffer
1069 which includes the assembled packet, which the application can
1070 use to encrypt the packet.
1072 Affected files are lib/silccore/silcpacket.[ch],
1073 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1074 silcd/packet_send.c, server_backup.c and packet_receive.c.
1076 * Fixed a packet sending bug on very high load, where outgoing
1077 packet queue wasn't handled correctly and packets got corrupted.
1078 Affected files are lib/silcutil/*/silc*sockconn.c,
1079 lib/silcclient/client.c and silcd/server.c.
1081 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1083 * Added macro SILC_PACKET_DATALEN which can be used during
1084 packet assembling to check whether the data to be added to
1085 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1086 len is truncated until it fits it.
1088 Added checks for maximum length of channel message payload and
1089 private message payload also.
1091 Added checks for maximum packet length in server and in
1094 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1095 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1096 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1097 lib/silcclient/client_prvmsg.c.
1099 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1101 * Added silc_server_packet_queue_purge call to the
1102 silc_server_disconnect_remote to assure that all data in the
1103 queue before disconnecting is sent to the network. Affected
1104 file silcd/server.c.
1106 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1108 * Added the deleting of server's own ID cache entry to the
1109 silc_server_free function. Free also everything else that
1110 has been allocated in silc_server_init. The affected file
1113 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Added functions silc_parse_version_string, silc_version_to_num,
1116 and silc_ske_parse_version to parse SILC protocol style version
1117 strings. Affected files lib/silcutil/silcutil.[ch] and
1118 lib/silcske/silcske.[ch].
1120 * Added new configuration params: version_protocol, version_software
1121 and version_software_vendor to specify what version the remote
1122 host must at least be to be able to connect to server. The vendor
1123 string can be regex matched too. Added new function
1124 silc_server_connection_allowed to check maximum number of allowed
1125 connections, and allowed versions for incoming connections.
1126 Affected files are silcd/server.c, server_util.[ch] and
1129 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1131 * Added preliminary support for signals in scheduler. The
1132 signals we care about are now blocked always when the scheduler
1133 is locked. This way we can synchronise the use of signal with
1134 scheduler. It is guaranteed that when signal occurs the scheduler
1135 is not locked, and thus new tasks can be safely added to the
1138 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1139 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1140 Added new platform specific routines
1141 silc_schedule_internal_signals_[un]block and
1142 silc_schedule_internal_signal_[un]register.
1144 Added new functions to SILC Schedule API:
1145 silc_schedule_signal_[un]register. Each signal that application
1146 is going to use should be registered to the scheduler.
1148 Affected files are lib/silcutil/silcschedule.[ch],
1149 lib/silcutil/*/silc*schedule.c.
1151 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1153 * Check for unauthenticated client and server in the
1154 silc_server_new_client and silc_server_new_server functions.
1155 Affected file silcd/packet_receive.c.
1157 * Added function silc_string_is_ascii to check whether given
1158 string is 7-bit ASCII string. Affected files are
1159 lib/silcutil/silcutil.[ch].
1161 * Added function silc_id_is_valid_server_id into the
1162 silcd/serverid.c and added checking for valid Server ID's in
1163 silc_server_new_server. The Server ID must always be based
1164 on the server's public IP address.
1166 * Added logging of DISCONNECT packet message in the server.
1167 Affected file silcd/server.c.
1169 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1171 * Changed all library interfaces that use Global RNG to also
1172 accept SilcRng as argument. Affected files are
1173 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1174 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1175 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1176 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1177 lib/silccrypt/rsa.c.
1179 * Added function silc_pkcs_generate_key to the
1180 lib/silccrypt/silcpkcs.[ch] for applications so that they
1181 don't need to do pkcs->pkcs->init calls anymore.
1183 * Remove SilcSocketConnection from the SFTP API since it really
1184 wasn't needed there. The application has the information
1185 saved in its contexts anyway and the SFTP layer doesn't need
1186 know about it. Affected files lib/silcsft/silcsftp.h and
1187 lib/silcsftp/sftp_[server/client].c.
1189 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1190 The SilcSimContext is not SilcSim.
1192 * Fixed possible buffer overflows in silc_id_render in the
1193 lib/silcutil/silcutil.c.
1195 * On EPOC the global crypto module lists are not used at all
1196 in the crypto library. Added support for using the constant
1197 algorithm list on EPOC. Affected files are
1198 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1201 * Fixed the handling of third parameter of KICKED notify, since
1202 it was mistakenly updated to SILC Protocol 1.0 even though it
1203 is to be included in 1.1. Since it is not in 1.0 it is not
1204 mandatory, and this fix now handles it only if it is provided,
1205 and it is not error if it is not provided. Affected file
1206 lib/silcclient/client_notify.c.
1208 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1211 client. Affected file irssi/src/silc/core/client_ops.c.
1213 * Merged with Irssi 0.8.4 from irssi.org CVS.
1215 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Check for valid socket connection in client entries before
1218 sending any messages. Fixes a crash, but doesn't fix some
1219 other underlaying bug that is lurking there. Affected
1220 file silcd/packet_send.c.
1222 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1224 * $usermode, $cumode and $cumode_space expandos shouldn't do
1225 anything with non-SILC server records. Affected file
1226 irssi/src/silc/core/silc-expandos.c
1228 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1230 * Fixed the silc_net_check_[host/local]_by_sock to support
1231 IPv6 bound sockets as well. Now they can return IPv6 addresses
1232 as well. Affected file lib/silcutil/silcnet.c.
1234 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1235 Affected lib/silcutil/unix/silcunixnet.c.
1237 * Fixed ID rendering (at least on some platforms, not NetBSD)
1238 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1240 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Added silc_hash_public_key and silc_hash_public_key_compare
1243 functions to be used with SilcHashTable. They can be used to
1244 hash public keys and compare public keys in hash table. Affected
1245 file lib/silcutil/silcutil.[ch].
1247 * Added support for specifying multiple public keys for Client
1248 connection section in server configuration file. This makes it
1249 possible to accept multiple public keys from same host, or to
1250 make a section that accepts any incoming host, and have the
1251 accepted public keys listed in the section.
1253 Added functions silc_sever_[find/get]_public_key, added the
1254 support for this actually to all connection sections but only
1255 the Client section is currently allowed to specify multiple
1258 Affected files are silcd/server.c, server_internal.h,
1259 command.c, protocol.c, server_util.[ch], packet_receive.c.
1261 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1263 * Merged Irssi 0.8.2 from irssi.org CVS.
1265 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1267 * If silc_debug is TRUE, also output standard logging messages
1268 to stderr with the debug output.
1270 Made silc_log_reset_all() flushing all channels before returning.
1271 Also fixed some documentation typos.
1273 Affected files are lib/silcutil/silclog.[ch].
1275 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed the server to check correctly the amount of connections
1278 from single host, by checking also the type of the connection.
1279 Fixed also the comparison of number of connections and number
1280 of allowed connections. Affected files are silcd/server.c,
1283 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1285 * Fixed the USERS command reply to save the user's mode on the
1286 channel as well. Fixed JOIN command reply to check whether a
1287 client is on channel already and not join it twice. Affected
1288 file lib/silcclient/command_reply.c.
1290 * Added new file silc-expandos.c into irssi/silc/core/ to return
1291 various stuff for various signal for the statusbar etc. updating.
1292 Now Irssi SILC client prints channel user modes etc. on the
1295 * The user mode (like server/router operator changes) is now shown
1296 on the Irssi SILC client's statusbar. The affected files are
1297 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1299 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1302 to SILC_SCHEDULE_[UN]LOCK macros.
1304 * Added more error printing to logs in server code. Affected
1305 files silcd/server.c and silcd/protocol.c.
1307 * Fixed -S option parsing in Irssi SILC Client. Affected file
1308 irssi/src/silc/core/silc-core.c.
1310 * Added silc_buffer_alloc_size function. Affected file is
1311 lib/silcutil/silcbuffer.h.
1313 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1315 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1316 constants. Affected files in
1317 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1320 * Changed the internal SFTP Memory FS table to const. Affected
1321 file lib/silcsftp/sftp_fs_memory.c.
1323 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1325 * Fixed the buffer formatting and unformatting routines to
1326 check the size of 64 bits types with sizeof(). Affected
1327 file is lib/silcutil/silcbuffmt.c.
1329 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Removed 0.6.x backwards support.
1333 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1335 * Changed all integer type names:
1336 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1337 to avoid collisions with other libraries using same type names
1340 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Added `prefer_ipv6' argument to the functions
1343 silc_net_gethostbyname[_async]. If it is TRUE it will return
1344 IPv6 address over IPv4. If FALSE IPv4 address is returned
1345 even if IPv6 address was found. Affected files
1346 lib/silcutil/silcnet.[ch].
1348 * Added support silc_net_create_connection[_async] to fallback
1349 to IPv4 address if IPv6 address could not be used (like if
1350 it doesn't work on a specific system). Affected file in
1351 lib/silcutil/unix/silcunixnet.c.
1353 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1359 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1361 * Added automatic extern "C" { ... } for C++ compilers so the
1362 application does not need to define them. Affected file
1363 includes/silcincludes.h.
1365 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1366 old name went against naming convention. Applications now
1367 include "silcclient.h" instead of "clientlibincludes.h".
1368 Removed includes/clientlibincludes.h, it is redundant now.
1370 * Renamed includes/version.h to silcversion.h.
1372 * Added really preliminary support for OS/2 into the util
1373 library. Only thread & mutex API is implemented, others
1374 are still to be implemented. Created the lib/silcutil/os2/
1375 directory. Created also file includes/silcos2.h.
1377 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Added preliminary BeOS support into the util library.
1380 Created lib/silcutil/beos/, and implemented all the needed
1381 functions to support SILC on BeOS. Created also file
1382 includes/silcbeos.h.
1384 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1386 * Added proper initializations to silc's irssi code, so it's
1387 now possible to load it as module. Affected files
1388 irssi/src/silc/core/silc-core.c,
1389 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1391 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1393 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1396 * Fixed the silcdoc document generator to correct generate
1397 docs from all kinds of filenames. Affected files are
1398 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1400 * ROBOdoc documented lib/silcutil/silcmemory.h.
1401 Added also new function silc_memdup.
1403 * Removed lib/silcutil/silcbufutil.h and moved those routines
1404 to the lib/silcutil/silcbuffer.h.
1406 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1408 * Added `user_count' to the SilcChannelEntry which now tells the
1409 number of users on the channel. The user count is now saved
1410 in normal server of global channels as well. Affected files
1411 silcd/server.c, idlist.h, packet_receive.c and command.c.
1413 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1414 include file utility functions.
1416 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1417 instead of calling directly OS routines.
1419 * Fixed NICK change printing in Irssi SILC Client. Fixed
1420 KICKED notify printing in Irssi SILC Client. Affected file
1421 irssi/src/silc/core/client_ops.c.
1423 * Fixed a NICK change bug in client library, to not recreate the
1424 client_entry->channels hash table everytime nick is changed.
1425 Affected file lib/silcclient/client.c.
1427 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1429 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1430 the SKE interface a bit.
1432 * Fixed padding problem in PKCS#1. The padding was not actually
1433 random since the random number generator was used incorrectly.
1434 This security bug affects only when encrypting with PKCS#1, and
1435 it is not currently used at all in SILC. SILC only use signing
1436 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1438 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Rewrote the notify handling in Irssi SILC client to not call
1441 the events as signals. Fixes problems with Perl support.
1442 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1444 * Send the auto-nicking NICK command in client library with
1445 little timeout after connecting. The affected file is
1446 lib/silcclient/client.c.
1448 * Added following new config file settings:
1449 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1450 key_exchange_timeout, conn_auth_timeout, connections_max,
1453 Implemented all the new config settings handling in the server.
1455 Optimized the use of SKE Mutual flag usage. Use it only
1456 if connection authentication protocol is not based in public
1459 Renamed all SilcServerConfigSection* to SilcServerConfig*
1460 to have a bit shorter names.
1462 Affected files silcd/serverconfig.[ch], server.[ch], and
1465 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1467 * Cleaned up the listening sockets code, preparing for the rehash
1468 support. Affected file is silcd/server.c.
1470 * Fixed some output messages. Affected files are silcd/silcd.c,
1473 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1475 * Create lib/doc/silcrng_intro.html document as introduction
1476 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1478 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1480 * Fixes to the silcd config template. Affected file is
1481 doc/example_silcd.conf.in.
1483 * Removed type casts from silc_calloc(), conforming to the
1484 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1486 * Removed param_name member from client, server, and router
1487 section structs, now identifying the param directly.
1489 Added CONFIG_FREE_AUTH macro in config file parsing.
1491 Affected files are silcd/serverconfig.[ch].
1493 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1495 * Fixed command line parameter handling. All SILC initialization
1496 is now done in silc_core_init() which also fixes autoconnecting
1499 Affected files irssi/src/silc/core/silc-core.c,
1500 irssi/src/fe-text/silc.c.
1502 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1504 * Added new configuration options and blocks:
1505 keepalive_secs, reconnect_count, reconnect_interval,
1506 reconnect_interval_max, reconnect_keep_trying and
1507 require_reverser_lookup. Added ConnectionParam block, and
1508 implemented the connection parameters when connecting as
1509 initiator and when accepting connections as responder.
1511 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1512 whether given configuration value has been given already.
1514 Affected files silcd/serverconfig.[c], server.[c].
1516 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1517 algorithm parts and created new file silcalgs.conf, that
1518 is now included from the example_silcd.conf.in.
1520 * Optimized the silc_server_connect_to_router_second to take
1521 the connection configuration object from the SilcServerConnection
1522 object instead of finding it during the connecting phase.
1523 Added the configuration object to SilcServerConnection struct.
1524 Affected files silcd/server_internal.h, server.c.
1526 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1528 * Add the client on channel after it was resolved at the
1529 channel message receiving, and it was not already on the
1530 channel. Affected file lib/silcclient/client_channel.c.
1532 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * Fixed the public key authentication to allocate always the
1535 destination signature buffer instead of using static buffer.
1536 Affected file silcd/protocol.c.
1538 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1540 * Unified the serverconfig.[ch]'s helper function interface.
1541 Affected file silcd/serverconfig.[ch].
1543 * Removed doc/example_silc.conf.in since it is redundant.
1544 The make install will now install irssi/silc.conf file.
1546 * Added new Passphrase and Publickey authentication methods to
1547 config file, allowing both public key and passphrase based
1548 authentication to be set at the same time.
1550 Added `prefer_passphrase_auth' setting in config file which
1551 can be used to set to prefer passwd auth if both passwd and
1552 public key is set. If not set, public key is preferred.
1553 This has effect only when being initiator (responder will try
1556 Added support for authentication with passphrase and public key
1557 at the same time. The passphrase is tried first always since
1558 it is faster to check.
1560 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1562 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1564 * Merged the new SILC Config library, with the server parsing
1565 support. Read the header file silcconfig.h or the toolkit
1566 documentation for the news. Affected files are
1567 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
1568 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
1569 silcd/protocol.c silcd/server.c silcd/server_backup.c
1570 silcd/serverconfig.[ch] silcd/silcd.c.
1572 * Fixed some silclog documentation. Affected file is
1573 lib/silcutil/silclog.h.
1575 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1577 * The silc_cipher_register, silc_hash_register and
1578 silc_hmac_register now checks if the object to be registered
1579 is registered already. Affected files are
1580 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1582 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1588 * Allow zero length channel messages inside the Channel Message
1589 Payload. Affected file lib/silccore/silcchannel.c.
1591 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1592 as header filenames.
1594 * Removed lib/silcclient/README and created HTML file
1595 lib/silcclient/silcclient_using.html, which is now included
1596 as part of Toolkit documentation.
1598 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1600 * Fixed CUMODE_CHANGE notify handling to change the mode of
1601 correct client. Affected file lib/silcclient/client_notify.c.
1603 * Make silc_rng_alloc fail if it cannot allocate the sha1
1604 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1606 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1608 * Fixed the file transfer's key agreement payload to include
1609 zero port also if the hostname is NULL because it could not
1612 Call file transfer monitor callback now also if error occurs
1613 during key agreement protocol.
1615 Changed the silc_client_file_send interface to return the
1616 SilcClientFileError instead of session id. The session ID
1617 is returned into pointer provided as argument.
1619 Check that the file exists locally before sending the
1620 file transfer request at all.
1622 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1624 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1625 error than can occur while key agreement protocol. Affected
1626 file lib/silcclient/silcapi.h.
1628 * Fixed the event_mode CMODE handler to not crash when mode
1629 is changed and +k mode is set in the channel. Affected file
1630 irssi/src/silc/core/silc-channels.c.
1632 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1633 SILC_LOG_WARNING to give out Warning and not Error. Affected
1634 file lib/silcutil/silclog.c.
1636 * Fixed the channel message payload decryption in the function
1637 silc_channel_message_payload_decrypt to not modify the original
1638 buffer before it is verified that the message decrypted
1639 correctly. Otherwise, next time it is called with correct
1640 channel key it won't encrypt since the payload is corrupted.
1641 Affected file lib/silccore/silcchannel.c.
1643 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Do not constantly resize the window. A fix patch by cras.
1646 Affected file irssi/src/fe-text/screen.c.
1648 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1650 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1651 Affected file lib/silcutil/silcnet.c.
1653 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1655 * Fixed a bug in hash table internal routine for traversing
1656 the table with foreach callback. The current entry may
1657 become invalid in the callback but it was referenced after
1658 the callback returned.
1660 Do not allow auto rehashing of hash table during the
1661 silc_hash_table_foreach operation, for same reasons as it is
1662 not allowed for SilcHashTableList. Affected files are
1663 lib/silcutil/silchashtable.[ch].
1665 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1667 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1668 Win32 DLL. extern's in header files are now declared with
1671 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1673 * Fixed private message handling. It used some old code that
1674 caused the client to crash. Affecte file is
1675 lib/silcclient/client_prvmsg.c.
1677 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Added function silc_client_add_channel,
1680 silc_client_replace_channel_id, and removed functions
1681 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1682 from client library.
1684 * Added cross reference of the joined channels to the
1685 SilcClientEntry, and changed the SilcChannelEntry's
1686 users list to SilcHashTable. The affected files are
1687 lib/silcclient/idlist.[ch].
1689 * Fixed a bug in hash table tarversing. While the hash table
1690 is traversed with SilcHashTableList the table must not be
1691 rehashed. It is now guaranteed that auto rehashable tables
1692 are not rehashed while tarversing the list. Also defined that
1693 silc_hash_table_rehash must not be called while tarversing
1694 the table. Added function silc_hash_table_list_reset that must
1695 be called after the tarversing is over. The affected files are
1696 lib/silcutil/silchashtable.[ch].
1698 * Changed all hash table traversing to call the new
1699 silc_hash_table_list_reset in server and in client library.
1701 * Added function silc_client_on_channel to return the
1702 SilcChannelUser entry if the specified client entry is joined
1703 on the specified channel. This is exported to application as
1704 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1706 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Fixed founder regaining problem with JOIN command on normal
1709 server. The notify for mode change must be sent always and
1710 not only if !cmd->pending. Affected file silcd/command.c.
1712 * Fixed the WHOWAS command's reply sending to support the
1713 lists correctly. Affected file silcd/command.c.
1715 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1717 * When sending JOIN command to router for processing the
1718 sender's old command identifier was not saved back to the
1719 sender's command context, fixed now. The affected file is
1722 * Create the key in JOIN command of the router did not return
1723 the channel key, added check for this. Affected file is
1726 * Fixed a channel ID update bug in JOIN command reply. Do
1727 not directly upgrade the ID but call the function
1728 silc_idlist_replace_channel_id if the ID was changed.
1729 Affected file silcd/command_reply.c.
1731 * Fixed memory leaks from command calling if it would fail.
1732 Affected file silcd/command.c.
1734 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1736 * Applied patches from cras:
1738 Memory leak fixes around libaries, irssi window resize fix,
1739 new silclist.h and silcdlist.h, all extern inline changed to
1742 * Removed dotconf from lib/dotconf, not needed anymore.
1744 * Removed TRQ from lib/trq, not needed anymore.
1746 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1747 with server connections. Later this will be configurable
1748 in config file after new config file is done. Affected file
1751 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1753 * Fixed a crash in server related to channel announcements.
1754 Affected file silcd/server.c.
1756 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1758 * Fixed memory leaks in silc_server_create_new_channel*
1759 functions. Affected file silcd/server.c.
1761 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1762 which ID was changed. This way the router will send the
1763 user list for the channel again, and server won't be in
1764 desync in some rare circumstances. Affected file is
1765 silcd/packet_receive.c.
1767 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Check for NULL socket pointer in the function
1770 silc_server_packet_send_to_channel_real. Affected file
1771 silcd/packet_send.c.

1774 list. Affected file silcd/packet_receive.c.
1776 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1778 * Fixed some header addition to Toolkit distribution in
1779 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1781 * Added lib/silcclient/client_ops_example.h as an template
1782 file for application programmers to quickly start using
1783 the SilcClientOperation functions in their application.
1784 Updated the lib/silcclient/README as well to tell about this
1785 nice file made available.
1787 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1789 * Call silc_server_remove_from_channels when removing client
1790 entry when NO_SUCH_CLIENT_ID was received. Affected file
1791 is silcd/command_reply.c.
1793 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1795 * Added server & router operator statistics updating. Affected
1796 file silcd/packet_receive.c and silcd/command.c.
1798 * Fixed the SERVER_SIGNOFF notify handling on normal server
1799 not to save the history information for clients. Same was
1800 fixed earlier in remove_clients_by_server function, but not
1801 here. Affected file silcd/packet_receive.c.
1803 * Raised the default connection-retry count from 4 to 7 in
1804 server. Affected file silcd/server.h.
1806 * Cancel any possible reconnect timeouts when we start the
1807 key exchange. Affected file silcd/server.c.
1809 * Do not reconnect on connection failure when SCONNECT was
1810 given. Affected files silcd/server.[ch].
1812 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1814 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1816 * Fixed the NICK command to always give the unformatted
1817 nickname to the one giving the NICK command. If unformatted
1818 nickname is cached already it will be formatted and the
1819 local entry will always get the unformatted nickname.
1820 Affected file lib/silcclient/idlist.c.
1822 * Fixed some double frees from client library commands.
1823 Affected file is lib/silcclient/command.c.
1825 * Fixed CUMODE command in server to assure that no one can
1826 change founder's mode than the founder itself, there was a
1827 little bug. Affected file silcd/command.c.
1829 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1831 * Removed the SilcClientCommandDestructor from the client
1832 libary, it is not needed anymore. Affected files are
1833 lib/silcclient/silcapi.h, command[_reply].[ch],
1834 client_notify, idlist.c.
1836 * Fixed GETKEY command to first resolve client, and then
1837 resolve the server only if the client was not found, instead
1838 of resolving both at the same time. Affected file is
1839 lib/silcclient/command.c.
1841 * Added silc_client_start_key_exchange_cb and lookup the
1842 remote hostname and IP address before starting the key
1843 exchange with server. The affected file is
1844 lib/silcclient/client.c.
1846 * The server's public key is now saved using the IP address
1847 of the server and not the servername for the filename.
1848 The hostname public key filename is checked as an fall back
1849 method if the IP address based filename is not found.
1851 Fixed the GETKEY command to save the fetched server key
1852 in correct filename.
1854 Print the remote server's hostname now when new key is
1855 received during connection process. Affected file is
1856 irssi/src/silc/core/client_ops.c.
1858 * Return always our own public key to the client if it asks
1859 for it with GETKEY command. Affected file silcd/command.c.
1861 * Removed the use_auto_addr variable from default config
1862 file since it was in wrong section. Affected file is
1865 * Fixed TOPIC_CHANGE notification to not route it when it
1866 was sent using silc_server_send_notify_to_channel function.
1867 Affected file silcd/command.c.
1869 * Fixed silc_server_send_notify_kicked to send the kicker's
1870 Client ID also, it was missing. Affected files are
1871 silcd/command.c, silcd/packet_send.[ch].
1873 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Do not save client history information in SERVER_SIGNOFF.
1876 Fixes the bug in normal server that it does not detect
1877 the client becoming valid after the server becomes back
1878 online. Affected file silcd/server_util.c.
1880 * Added `sock_error' field into the SilcSocketConnection
1881 context. When error occurs during socket operation (read
1882 or write) the error is saved. Added also new function
1883 silc_socket_get_error to return human readable socket error
1884 message. Affected files are lib/silcutil/silcsockconn.[ch],
1885 lib/silcutil/unix/silcunixsockconn.c, and
1886 lib/silcutil/win32/silcwin32sockconn.c.
1888 * The server now prints the socket error message in the
1889 signoff for client. Affected file silcd/server.c.
1891 * Fixed the `created' channel information sending from router
1892 to server in JOIN command. Checks now whether the channel
1893 really was created or not and set it according that.
1895 Fixed the JOIN command to use the client entry's current
1896 ID during the joining procedure instead of the one it sent
1897 in the command (it is checked though), since it can change
1898 between the packet processing and command processing, and
1899 would just case unnecessary pain in the client end. Affected
1900 file silcd/command.c.
1902 * Fixed a channel key payload sending to use correct channel
1903 ID when the server was forced to change the channel's ID by
1904 router. Router sent the key payload with the old Channel ID.
1905 Affected file silcd/packet_receive.c.
1907 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1909 * Call silc_server_save_channel_key only if the key payload
1910 was provided in the JOIN command's command reply. Affected
1911 file silcd/command_reply.c.
1913 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1915 * Fixed silc_mp_sizeinbase to return the value correctly with
1916 MPI. Affected file lib/silcmath/mp_mpi.c.
1918 * Fixed the stop_server signal to correctly stop the scheduler
1919 and gracefully stop the server when SIGTERM or SIGINT signals
1920 are received. Affected file silcd/silcd.c.
1922 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1924 * Simple handling of TERM and HUP signals. Also added some log
1925 flushing call around. Affected file is
1928 * Fixed small bugs in silclog.c. Now buffering output will take
1929 effect after 10 seconds since startup: This will ensure that
1930 no important startup messages are lost. Also output redirection
1931 will preserve original format ([Date] [Type] message).
1932 Affected file is lib/silcutil/silclog.c.
1934 * Added two options to the config file, in the logging section:
1935 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1936 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1938 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not print the warning about log files not being initialized
1941 more than once to avoid excess logging. Affected file is
1942 lib/silcutil/silclog.c.
1944 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1945 the SIM copying in make install in Makefile.am.pre.
1947 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1949 * Rewritten silclog APIs. Globally interesting changes follows:
1950 silc_log_set_files() changed to silc_log_set_file().
1951 silc_log_set_callbacks() changed to silc_log_set_callback().
1952 ROBOdoc documented silclog header file.
1953 SilcLogCb now returns bool to wether inihibit the default
1954 handler or not (to keep the old behaviour return always TRUE).
1955 The new APIs should also fix the problem of the
1956 silcd_error.log file that was written in the current directory.
1959 Log files streams will remain opened after silc_log_set_file()
1960 call, means less CPU usage notably on high traffic servers.
1961 File streams are now full buffered, and flushed to the disk
1962 every 5 minutes, lesses HD activity and CPU usage.
1963 Messages can be redirected, allowing admins to configure
1964 one single logfile for all server messages.
1965 the silc_log_quick global variable to activate fast-logging.
1966 Affected files lib/silcutil/silclog.[ch]
1968 * Changed some code to conform new silclog APIs. Affected
1969 files are doc/example_silcd.conf.in, silcd/server.c
1970 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1973 * Fixed a memory leak that could occur in some situations.
1974 Affected file silcd/serverconfig.c.
1976 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1978 * Added the silc_client_del_client to remove the client from
1979 all channels as well. Affected file lib/silcclient/idlist.c.
1981 * Fixed the client library to correctly remove the client
1982 from all channels when the client entry is being destroyed.
1983 Affected file lib/silcclient/client_notify.c, command.c.
1985 * Added auto-nicking support to the client library. If the
1986 applicatio now sets client->nickname it will be sent to the
1987 server after connecting by the library. This way for example
1988 SILCNICK (or IRCNICK) environment variables will have effect
1989 and always change the nickname automatically to whatever
1990 it is wanted. Affected file lib/silcclient/client.[ch].
1992 * Renamed silc_server_command_bad_chars to the
1993 silc_server_name_bad_chars and moved it to the
1994 silcd/server_util.[ch]. Added also new function
1995 silc_server_name_modify_bad to return nickname that
1996 includes bad characters as new nickname without those
1997 bad characters. This check and modify is now used in
1998 silc_server_new_client when the username is initially set
1999 as nickname, so it must be checked to be valid nickname.
2000 Affected file silcd/packet_receive.c.
2002 * The nickname length is now taken from the packet for real
2003 and not trusted to strlen() since it clearly can return
2004 wrong length for nickname including bad characters. This
2005 also applies to channel names. Affected file silcd/command.c.
2007 * Removed the lib/silcsilm/modules directory. Modules are now
2008 compiled into the lib/silcsim. Fixed the copying of the
2009 modules to follow symbolic links in Makefile.am.pre.
2011 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2013 * Fixed silc_string_regexify list creation. Fixes bugs with
2014 BAN and INVITE commands in server. The affected file is
2015 lib/silcutil/unix/silcunixutil.c.
2017 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Removed the command destructor entirely from the server's
2020 command and command reply routines. It is not needed, and
2021 its usage was buggy and caused crashes. Affected files are
2022 silcd/command[_reply].[ch].
2024 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Cancel protocol and NULL sock->protocol if timeout
2027 occurred during protocol. Affected file silcd/server.c.
2029 * Cancel protocol timeouts always before calling the final
2030 callback, to assure that after final callback is called
2031 no other state will be called for the protocol anymore.
2032 Affected file silcd/protocol.c.
2034 * Print error log if incoming connection configuration could
2035 not be found. Affected file silcd/server.c.
2037 * Fixed JOIN command to correctly save the founder mode
2038 to the client on normal SILC server, when the channel
2039 was created by the router. Affected file silcd/command.c.
2041 * Fixed LIST command (hopefully) to send correct reply
2042 packets. Affected file silcd/command.c.
2044 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * The silc_packet_receive_process now returns FALSE if the
2047 read data was invalid packet, and TRUE if it was ok.
2049 The server now checks that if unauthenticated connection
2050 sends data and its processing fails the server will close
2051 the connection since it could be a malicious flooder.
2053 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2055 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Make sure the warning about error opening a log file is
2058 printed only once and not everytime it fails (produces
2059 too much useless log). Affected file lib/silcutil/silclog.c.
2061 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2063 * Made the silc_server_daemonise() function more readable.
2064 Affected file silcd/server.c.
2066 * Pid file is now optional, the user may comment it out from
2067 the config file. Removed define SILC_SERVER_PID_FILE, we
2068 don't need a default any longer. Affected file
2069 configure.in.pre, lib/Makefile.am.pre.
2071 * Make some use of the pid file. The server now dies at startup
2072 if it detects a valid pid file on his path. The server would
2073 die anyway in this circumstance, because of the bind() failure.
2074 Affected file silcd/silcd.c.
2076 * No longer compiling lib/dotconf.
2078 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Fixed JOIN command parsing not to crash. Affected file
2081 lib/silcclient/command.c.
2083 * Fied the NICK_CHANGE notify to add the new client entry
2084 even it is resolved. This removes an <[unknown]> nick
2085 thingy bug in the client. Affected file is
2086 lib/silcclient/client_notify.c.
2088 * Do not try to allocate 0 bytes (efence does not like it)
2089 in lib/silccore/silccomand.c when encoding payload.
2091 * Do not take IRCNICK as nickname in Irssi SILC client since
2092 it is not possible to set nickname before hand connecting
2093 the server (TODO has an entry about adding auto-nicking
2096 * Changed the silc_server_command_pending to check whether
2097 there already exists an pending entry with the specified
2098 command, command identifier and pending callback. This is
2099 to fix IDENTIFY and WHOIS related crashes that may register
2100 multiple pending commands with same identifier. Affected
2101 file silcd/command.c.
2103 * Fixed the server to reconnect to the router even if it
2104 was already reconnecting and EOF was received. This to
2105 fix a possibility that the server wouldn't ever try to
2106 auto-reconnect to the router. Affected file silcd/server.c.
2108 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Fixed the server's password authentication to use the
2111 length of the locally saved password, and not the one
2112 sent in the packet. Affected file silcd/protocol.c.
2114 * Fixed same password authentication problem in the
2115 Authentication Payload handling routines in
2116 lib/silccore/silcauth.c.
2118 * Yet another password authentication problem fixed with
2119 channel password handling in silcd/command.c.
2121 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * If first character of string in silc_parse_userfqdn is '@'
2124 then do not parse it. Affected file is
2125 lib/silcutil/silcutil.c.
2127 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Fixed minor bug in IDENTIFY command reply sending, which
2130 caused various weird problems during JOIN when it was
2131 resolving names for users. Affected file silcd/command.c.
2133 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Fixed the IDENTIFY command reply sending to chech better valid
2136 clients. It was possible to send incomplete list of replies.
2137 Affected file silcd/command.c.
2139 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Added silc_client_command[s]_[un]register functions now to
2142 dynamically register the commands in client library. Removed
2143 the static table of commands. This allows the client library
2144 to call commands without causing the application to know about
2145 what commands library has called.
2147 Removed the INFO command reply kludge to detect when the command
2148 was called by library. Now library use its own command reply
2149 function for INFO command.
2151 Added function silc_client_command_call to call a command.
2152 Application can use it to call command, not access the structure
2155 Now all commands that are sent by the client library (not
2156 explicitly sent by application) use own command reply functions.
2158 Affected files around lib/silcclient/ and in
2159 irssi/src/silc/core/.
2161 * Fixed the WHOIS command reply sending to chech better valid
2162 clients. It was possible to send incomplete list of replies.
2164 Fixed the WHOIS and IDENTIFY to send the request to router
2165 if normal server did not do it and did not find any results.
2167 Affected file silcd/command.c.
2169 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Moved the internal data from SilcClient context into its
2172 own file, not accesible to application. Affected files
2173 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2174 and other files in client library.
2176 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Added doc/examples installation target in Makefile.am.pre.
2181 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2184 commands the found client entry will be removed from the
2185 cache, after notifying application about the error. Affected
2186 file lib/silcclient/command_reply.c.
2188 * Changed the /MSG to check for exact nickname user gave, and
2189 not let `nick' match `nick@host' if it is only one found. Now,
2190 user must type the exact nickname (like nick@host2) even if
2191 there are no more than one same nicks found. This is to avoid
2192 a possibility of sending nickname to wrong nickname since
2193 `nick' could match `nick@host'. Affected file is
2194 irssi/src/core/silc-servers.c.
2196 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Do not print "you are now server operator" or similar when
2199 giving /away command. Affected files are
2200 irssi/src/silc/core/client_ops.c, silc-servers.h.
2202 * Made the silc_server_command_pending_error_check to send
2203 the same command reply payload it received back to the
2204 original sender of the command. This way all arguments
2205 that was received by the server will be received by the
2206 client too. Affected file silcd/command.c.
2208 * Added the silc_idcache_add to return the created cache entry
2209 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2211 * Add global clients to expire if they are not on any channel.
2212 This is because normal server will never know if they signoff
2213 if they are not on any channel. The cache expiry will take
2214 case of these entries. This is done by normal servers only.
2215 The affected files are silcd/command_reply.c,
2216 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2218 * If server receives invalid ID notification for WHOIS or
2219 IDENTIFY and the ID exists in the lists, it is removed.
2220 Affected file silcd/command_reply.c.
2222 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2223 in client then client entry that it matches is searched and
2224 the nickname is printed on the screen for user. Affected
2225 file irssi/src/silc/core/client_ops.c.
2227 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2229 * Use cache entry expire time in the LIST command reply to
2230 purge old entries from the cache after the LIST command
2231 reply has been received. This way we don't have non-existent
2232 entries in the cache for too long. Affected file is
2233 silcd/command_reply.c.
2235 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * If we are normal server, and we've not resolved client info
2238 in WHOIS or IDENTIFY from router, and it is global client,
2239 we'll check whether it is on some channel. If it is not
2240 then we cannot be sure about its validity and will resolve it
2241 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2242 file silcd/command.c.
2244 * Search channel by name (if possible) rather than by ID
2245 in IDENTIFY command's command reply. Affected file is
2246 silcd/command_reply.c.
2248 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2251 Updated specs and implemented it. Affected file silcd/command.c,
2252 silcd/packet_send.c and silcd/packet_receive.c.
2254 * Implemented the <founder auth> payload handling in the JOIN
2255 command. If provided all conditions for channel joining
2256 except requirement to provide correct passphrase can be
2257 overrided by the channel founder. Updated the protocol specs.
2258 Affected file silcd/command.c.
2260 Added support for founder auth in JOIN command in client
2261 library. Fixed the parsing of the JOIN command now to support
2262 all options as they should be. The affected file is
2263 lib/silcclient/command.c.
2265 * Optimized the WHOIS and IDENTIFY commands to send the request
2266 to router only if it includes nicknames or other names. If
2267 they include only IDs then check the local cache first before
2268 routing. Affected file is silcd/command.c.
2270 * Added channels topic announcements. Affected file is
2271 silcd/packet_receive.c and silcd/server.c.
2273 * Fixed the silc_server_send_notify_topic_set to really destine
2274 the packet to channel. Affected file silcd/packet_send.c.
2276 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2277 library. Affected file lib/silcclient/client_notify.c.
2279 * Added UMODE announcements. Affected file silcd/server.c.
2281 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Memory leak fixes in:
2285 lib/silcutil/silcsockconn.c
2286 lib/silcske/silcske.c
2287 lib/silcske/groups.c
2289 lib/silccrypt/silcpkcs.c
2290 lib/silccore/silccommand.c
2291 lib/silccore/silcidcache.c
2296 * ROBOdoc documented the lib/silcske/groups.h file and a
2297 bit changed the interface for better.
2299 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2301 * Update the client entry context in the ID cache after
2302 nick change. Affected file lib/silcclient/command.c.
2303 Fixes the CUMODE command when regaining founder privileges,
2304 and a little WHOIS problem.
2306 * Fixed silc_net_gethostbyname to correctly call the
2307 inet_ntop. Affected file lib/silcutil/silcnet.c.
2309 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2311 * Added IPv6 support checking to the configure.in.pre, added
2312 also --enable-ipv6 option to override the check. Affected
2313 file configure.in.pre.
2315 * The silc_thread_create now calls the start function
2316 directly if threads support is not compiled in. Removes
2317 ugly #ifdef's from generic code. Affected files are
2318 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2320 * Added silc_net_gethostby[name/addr]_async to asynchronously
2321 resolve. Affected files are lib/silcutil/silcnet.[ch].
2323 * Added support for rendering IPv6 based server, client and
2324 channel IDs. Affected file lib/silcutil/silcutil.c.
2326 * Added support for creating IPv6 based server IDs. Affected
2327 file is silcd/serverid.c.
2329 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2331 * Added silc_net_gethostby[addr/name] into the
2332 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2333 routines. Added silc_net_is_ip[4/6]. Affected file is
2334 lib/silcutil/unix/silcunixnet.c. All routines that take
2335 address as argument now supports both IPv4 and IPv6 addresses.
2337 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2339 * Fixed LIST command reply sending in server. Affected file
2342 * Server now sends the kicker's client ID in the KICK notify
2343 to the kicked client. Affected file silcd/command.c.
2345 * The client library now parses the kickers client ID and
2346 UI displays it. Affected files lib/silcclient/client_notify.c
2347 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2349 * Made all payload parsing function prototypes consistent.
2350 They all take now const unsigned char * and uint32 pair as
2351 the payload data instead of SilcBuffer. Changes all around
2352 the source tree. Other unsigned char* -> const unsigned char*
2353 changes around the tree as well.
2355 * Optimized SFTP client and server packet sending not to
2356 allocate new buffer for each packet but to recycle the
2357 first allocated buffer. Affected files are
2358 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2360 * Optimized the SFTP client to use SilcList instead of
2361 SilcDList for requests, because it is faster. Affected file
2362 is lib/silcsftp/sftp_client.c.
2364 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2365 into lib/silccore/silcid.[ch].
2367 Renamed silcpayload.[ch] into silcargument.[ch].
2369 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * If client entry is deleted with active key agreement
2372 session, abort the session.
2374 The silc_client_abort_key_agreement now calls the completion
2375 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2377 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2380 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Don't use __restrict in older GCC's. Affected file is
2383 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2385 * silc_net_localhost now attempts to reverse lookup the
2386 IP/hostname. Affected file lib/silcutil/silcnet.c.
2388 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2389 command. It can be used to gain founder privileges at
2390 the same time when joining the channel.
2392 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2393 kicker's client ID as well. Updated protocol specs.
2395 Defined that the server must send SILC_COMMAND_IDENTIFY
2396 command reply with error status to client who sent
2397 private message with invalid client ID.
2399 Updated the protocol specification.
2401 * Added silc_server_send_command_reply to send any
2402 command reply. Affected file silcd/packet_send.[ch].
2404 * Added silc_id_payload_encode_data to encode ID payload
2405 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2407 * The server now send IDENTIFY command reply with error
2408 status if client ID in private message is invalid. Affected
2409 file silcd/packet_receive.c.
2411 * Save the server key file with server's IP address in
2412 the filename instead of hostname. The affected file is
2413 irssi/src/silc/core/client_ops.c.
2415 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2420 * Added libtool support for compiling shared objects in
2421 lib/silcsim. Affected file configure.in.pre and
2422 lib/silcsim/Makefile.am. Original patch by cras.
2424 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Pid file configuration, and server's config file fixes
2427 patch by toma. Updated CREDITS file.
2429 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Fixed silc_client_channel_message to not try to decrypt
2432 the message twice if it resolved the destination client
2433 information. This could cause of dropping one channel
2434 message. Affected file lib/silcclient/client_channel.c.
2436 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2439 lib/silcclient/client.c. This function is used when the SILC
2440 Client is run under some other scheduler, or event loop or
2441 main loop. On GUI applications, for example this may be
2442 desired to used to run the client under the GUI application's
2443 main loop. Typically the GUI application would register an
2444 idle task that calls this function multiple times in a second
2445 to quickly process the SILC specific data.
2447 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2449 * Fixed silc_server_drop() for dropping the supplementary
2450 groups as well, this could cause a security hole on some
2453 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2458 * Write PID file after dropping privileges. Added -F option
2459 to run server on foreground. A patch by debolaz.
2460 Affected files silcd/server.c, silcd/silcd.c.
2462 * Fixed MOTD to return the MOTD file server name. Affected
2463 file silcd/command.c.
2465 * Added INFO command reply handling to the Irssi SILC Client.
2466 Affected file irssi/src/silc/core/client_ops.c.
2468 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed the silc_idcache_list_* routines to really support
2471 the dynamic list. Fixes a crash. Affected file is
2472 lib/silccore/silcidcache.c.
2474 * Fixed the LIST command reply to really call LIST command's
2475 pending callbacks. Affected file silcd/command_reply.c.
2477 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2479 * Update conn->local_entry->nickname after giving NICK
2480 command. Affected file lib/silcclient/command.c.
2482 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2484 * Added the [pid] option to the silcd configuration file
2486 Affected files: serverconfig.[ch] and silcd.c
2488 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Save fingerprint in WHOIS command reply in server.
2491 Affected file silcd/command_reply.c.
2493 * Fixed NICK commands pending callback registration.
2494 Affected file lib/silcclient/command.c.
2496 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Use ++server->cmd_ident when sending commands in server,
2499 instead of random number. Affected file silcd/command.c.
2501 * Fixed GETKEY command reply to call actually GETKEY pending
2502 command callbacks. Affected file silcd/command_reply.c.
2504 * A bit stricter check for nicknames. Check for same nickname
2505 in NICK command also. Affected file silcd/command.c.
2507 * Do not call INFO command everytime client ID changes, only
2508 during first connecting. Affected file lib/silcclient/client.c.
2510 * Set the new nickname only after successful command reply for
2511 NICK command is returned by server. Affected file
2512 lib/silcclient/command.c.
2514 * Remove nicknames from nicklist during server_signoff notify.
2515 Should fix /NAMES bit more. The affected file is
2516 irssi/src/silc/core/silc-channels.c.
2518 * Added `fingerprint' field to the SilcIDListData in the
2519 silcd/idlist.h to hold the fingerprint of the client's
2522 Send the fingerprint of the client's public key in WHOIS
2525 Affected files silcd/command.c, and silcd/idlist.[ch].
2527 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2528 create fingerprint from given data.
2530 * Show the fingerprint of the client's public key in WHOIS.
2531 Affected files irssi/src/module-formats.[ch] and
2532 irssi/src/silc/core/client_ops.c.
2534 * Format the multiple same nicknames also during JOIN and
2535 NICK_CHANGE notifys. Affected file is
2536 lib/silcclient/client_notify.c.
2538 * Do not print error on screen for invalid private message
2539 payload since it can come if someone is sending private
2540 messages with wrong key. Affected file
2541 lib/silccore/silcprivate.c.
2543 * Fixed multiple concurrent /PING crash. Affected file
2544 lib/silcclient/command.c.
2546 * Changed the wrong ID encoding. All IP addresses must be
2547 in MSB first order in encoded format. They were encoded
2548 wrong and was in LSB format. Affected files are
2549 silcd/serverid.c, lib/silcutil/silcutil.c.
2551 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2553 * Call the `connect' client operation through the scheduler
2554 in case of error. Affected file lib/silcclient/client.c.
2556 * Call the `failure' client operation even if the error
2557 occurred locally during a protocol. Affected file is
2558 lib/silcclient/protocol.c.
2560 * Added support of sending LIST command to router from normal
2561 server. This way normal server can get list of all channels
2562 in the network too. Fixed the channel list sending in the
2563 server too. Affected files are silcd/command.c, and
2564 silcd/command_reply.[ch].
2566 * Added silc_server_update_channels_by_server and
2567 silc_server_remove_channels_by_server. They are used during
2568 disconnection of primary router and in backup router protocol.
2569 Affected file silcd/server_util.[ch], silcd/server.c and
2570 silcd/server_backup.c.
2572 * Fixed channel adding to global list in IDENTIFY command
2573 reply in server. Affected file silcd/command_reply.c.
2575 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * If the incoming packet type is REKEY or REKEY_DONE process
2578 that packet always synchronously. Fixes yet another MAC
2579 failed error on slow (dialup) connections. Affected file
2580 lib/silcclient/client.c and silcd/server.c.
2582 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Call check_version SKE callback for initiator too. Affected
2585 file lib/silcske/silcske.c.
2587 * Implemented fix for security hole found in the SKE that was
2588 fixed in the specification few days back; the initiator's
2589 public key is now added to the HASH value computation.
2590 Added backwards support for the old way of doing it too, for
2591 old clients and old servers. Affected file is
2592 lib/silcske/silcske.c.
2594 * Enabled mutual authentication by default in SKE. If initiator
2595 is not providing mutual authentication the responder will
2596 force it. This will provide the proof of posession of the
2597 private key for responder. The affected files are
2598 lib/silcclient/protocol.c and silcd/protocol.c.
2600 * Do not cache anymore the server's public key during SKE.
2601 We do mutual authentication so the proof of posession of
2602 private key is done, and if the server is authenticated in
2603 conn auth protocol with public key we must have the public
2604 key already. Affected file silcd/protocol.c.
2606 * Added new global debug variable: silc_debug_hexdump. If
2607 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2608 file lib/silcutil/silclog.[ch].
2610 * Fixed compilation warning due to char * -> const char *.
2611 Affected files lib/silcutil/silcnet.h, and
2612 lib/silccore/silcauth.[ch].
2614 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed CMODE command when new channel key was created. If
2617 the creation failed the old key was removed. Next time giving
2618 same command would crash the server since the old key was
2619 freed already. Affected file silcd/command.c.
2621 * Fixed the silc_server_announce_get_channels to not crash
2622 on reconnect. Affected file silcd/server.c.
2624 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Added silc_log_set_debug_string function to set a regex
2627 string to match for debug output. Only the function names,
2628 or filenames matching the given debug string is actually
2629 printed. This way it is possible to filter out those debug
2630 strings that user is not interested in.
2632 Fixed a bug in silc_string_regexify.
2634 Affected files lib/silcutil/silclog.[ch], and
2635 lib/silcutil/unix/silcunixutil.c.
2637 * Changed the -d options in both server and Irssi SILC client
2638 to take the debug string as argument. Affected files
2639 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2641 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Added silc_hash_babbleprint to create a Bubble Babble
2644 Encoded fingerprint. The encoding is developed by Antti
2645 Huima (draft-huima-babble-01.txt), and it creates human
2646 readable strings out of binary data. Affected file
2647 lib/silccrypt/silchash.[ch].
2649 * Print the babble print now in addition of fingerprint as well
2650 in Irssi SILC client. Affected files are
2651 irssi/src/fe-common/silc/module-formats.[ch],
2652 irssi/src/fe-common/silc/core/client_ops.c.
2654 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Fixed a security problem found in SKE. The initiator's
2657 public key too is now added to the HASH hash value creation
2658 which is signed by the responder to create the SIGN value.
2659 This will prevent anyone in the middle to lie to the responder
2660 about the initiator's public key. If this is done now, the
2661 man in the middle will get caught. Updated the protocol
2664 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Better installation directory handling. Configure module
2667 paths and other paths automatically to example_silc* files
2668 in doc/. A patch by toma.
2670 * Fixed compiler warning from MPI library, and from SILC RNG.
2673 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2674 It can be configured with ./configure. A patch by toma.
2676 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Find correct make to use in prepare-clean. A patch by
2679 toma. Affected file prepare-clean.
2681 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2683 * Added irssi variables use_auto_addr, auto_bind_ip,
2684 auto_bind_port and auto_public_ip.
2686 * Changed the interface for silc_client_send_key_agreement
2687 in lib/silcclient/silcapi.h
2691 irssi/src/silc/core/silc-core.c
2693 lib/silcclient/silcapi.h
2694 irssi/src/silc/core/silc-channels.c
2695 lib/silcclient/client_keyagr.c
2698 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Added silc_pkcs_public_key_compare to compare two
2701 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2703 * Check that the client who set the founder mode on the
2704 channel is the same client that is giving the founder
2705 mode to itself. It is done by comparing the saved public
2706 key (it is saved even in the authentication is passphrase).
2707 Affected file silcd/command.c.
2709 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Do not process packet for disconnected socket connection.
2712 Affected file lib/silccore/silcpacket.c.
2714 * Process the DISCONNECT packet through scheduler in the
2715 client library. Affected file lib/silcclient/client.c.
2717 * Fixed the silc_client_packet_parse to not to increase
2718 the packet sequence number if the conn->sock and the
2719 current socket connection is not same. This can happen
2720 for example during key agreement when the conn includes
2721 multiple socket connections (listeners). Affected file
2722 lib/silcclient/client.c.
2724 * The sender of the file transfer request now provides also
2725 the pointer (listener) for the key exchange protocol. If
2726 the listener cannot be created then it sends empty key
2727 agreement and lets the receiver provide the listener.
2729 Added `local_ip' and `local_port' arguments to the
2730 silc_client_file_send. If they are provided they are used,
2731 if not then it will attempt to find local IP address, if
2732 not found or bind fails then the remote client will provide
2735 Affected files are lib/silcclient/client_ftp.c and
2736 lib/silcclient/silcapi.h.
2738 * Extended the FILE SEND command to support defining the
2739 local IP and port for key exchange listener. They are
2740 optional. Affected file irssi/src/silc/core/silc-servers.c.
2742 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Defined to WHOIS command reply the sending of fingerprint
2745 of the client's public key (if the proof of posession of the
2746 corresponding private key is verified by the server).
2747 Updated to the protocol specification.
2749 * Added support of receiving the client's public key's
2750 fingerprint in command reply in client library. Affected
2751 file is lib/silcclient/command_reply.c, and
2752 lib/silcclient/idlist.[ch].
2754 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Do not send over 128 chars long nickname to the server
2757 in NICK command. Affected file lib/silcclient/command.c.
2759 * Do not send over 256 chars long channel names to the server
2760 in JOIN command. Affected file lib/silcclient/command.c.
2762 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Assure that silc_server_close_connection cannot be called
2765 twice for same socket context. Affected file is
2768 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Send error message to application if opening file for
2771 writing during file transfer fails. Affected file is
2772 lib/silcclient/client_ftp.c.
2774 Remove all file transfer sessions for a client that we're
2775 removing from ID cache.
2777 Affected file is lib/silcclient/client_ftp.c.
2779 * Fixed silc_net_addr2bin to return correct address. Affected
2780 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2782 * Fixed file transfer session removing on signoff notify.
2783 Affected file irssi/src/silc/core/silc-servers.c.
2785 * Added the SilcClientFileError to be returned in the monitor
2786 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2787 Affected file lib/silcclient/silcapi.h.
2789 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Fixed a crash in silc_client_ftp_free_sessions and
2792 silc_client_ftp_session_free_client. Affected file
2793 lib/silcclient/client_ftp.c.
2795 * Added `disabled' field in the SilcChannelEntry in the server
2796 to indicate if the server entry is disabled. Affected file
2797 silcd/idlist.h, silcd/command[_reply].c.

2800 started. Affected file silcd/silcd.c.
2802 * Added silc_server_packet_send_clients to send a packet to
2803 the provided table of client entries. Affected file
2804 silcd/packet_send.[ch].
2806 * Fixed a crash in client resolving in client_prvmsg.c in
2807 client library. Affected file lib/silcclient/client_prvmsg.c.
2809 * Do not actually remove the client directly from ID cache
2810 during SERVER_SIGNOFF, but invalidate it. This way we
2811 preserve the WHOWAS info for the client. Affected file
2812 silcd/server_util.c.
2814 * Fixed SERVER_SIGNOFF notify handling in the server. The
2815 server is now able to process incoming SERVER_SIGNOFF notify
2816 for a server that it doesn't even know about. It will remove
2817 the clients provided in the notify. Affected file
2818 silcd/packet_receive.c.
2820 * Check for partial packet in data queue after every packet that
2821 was found from the queue. Return and wait for more data if
2822 there is partial data in queue. Affected file is
2823 lib/silccore/silcpacket.c.
2825 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Added SilcClietFileError enum to indicate error in
2828 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2829 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2830 Affected files lib/silcclient/silcapi.h and
2831 lib/silcclient/client_ftp.c.
2833 * Check that newsize in silc_buffer_realloc is larger than
2834 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2836 * Added better monitor of file transfers. It now monitors
2837 key agreement protocol during the file transfer too. Added
2838 error reporting too. Affected files
2839 irssi/src/silc/core/silc-servers.c,
2840 irssi/src/fe-common/silc/module-formats.[ch].
2842 * Wrote a help file for FILE command.
2844 * Added silc_rng_global_get_byte_fast to get not-so-secure
2845 random data as fast as possible. Random data is read from
2846 /dev/urandom if available and from the SILC RNG if not
2847 available. It is used in padding generation. Affected file
2848 lib/silccrypt/silcrng.[ch].
2850 * All packets in client library are now processed synchronously.
2851 Optimized packet processing a lot. Affected file
2852 lib/silcclient/client.c.
2854 * All server connection packets are processing synchronously
2855 now in server, to optimize packet processing. Affected file
2858 * Include files are installed now only in Toolkit distribution
2859 if make install is given. Affected files: all Makefile.am's.
2861 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Assure that silc_client_notify_by_server_resolve does not
2864 resolve the client information multiple times. If it cannot
2865 be found by the first it cannot be found at all. Affected
2866 file lib/silcclient/client_notify.c.
2868 * Fixed WHOWAS command reply calling. Affected file
2869 lib/silcclient/command_reply.c.
2871 * Removed all references to silc_idlist_get_client from the
2872 Irssi SILC client since that call is internal call used by
2873 the library. The Irssi SILC client will use now client
2874 retrieval functions found in silcapi.h.
2876 * Fixed a bug in resolving nickname info before sending
2877 private message. It used freed memory. Affected file
2878 irssi/src/silc/core/silc-servers.c.
2880 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Assure my_channels statistics cannot go negative in server.
2883 Affected files silcd/server.c, silcd/server_util.c.
2885 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2889 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

2899 * Added silc_net_localip to return local host's IP address.
2900 Affected file lib/silcutil/silcnet.[ch].
2902 * If key exchange or rekey protocol is active for a connection
2903 parse all packets syncronously since there might be packets
2904 in packet queue that we are not able to process without first
2905 processing packets before them. Affected file silcd/server,
2906 lib/silcclient/client.c.
2908 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2909 whether library should continue processing the packet.
2910 Affected file lib/silccore/silcpacket.h.
2912 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2913 SilcSFTPMonitorData to SFTP server to monitor various
2914 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2921 Added preliminary support for simple client to client one-file
2922 transmission. Affected file lib/silcclient/client_ftp.c,
2923 lib/silccilent/client.[ch].
2925 * Added new local command FILE to the Irssi SILC Client.
2926 It is used to perform the file transfer. It has subcommands
2927 SEND, RECEIVE, SHOW and CLOSE. Affected files
2928 irssi/src/silc/core/client_ops.c,
2929 irssi/src/silc/core/silc-server.[ch].
2931 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Relay the SILC_PACKET_FTP in the server. Affected files
2934 silcd/server.c and silcd/packet_receive.c.
2936 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Renamed silc_file_read and silc_file_write to functions
2939 silc_file_readfile and silc_file_writefile. Added function

2941 lib/silcutil/silcutil.[ch].
2943 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Resolve the client info when received private message or
2946 channel message for a client which nickname we don't know.
2947 Affected files lib/silcclient/client_prvmsg.c and
2948 lib/silcclient/client_channel.c.
2950 * Do not crash in /KEY if client is not connected. Affected
2951 file irssi/src/silc/core/silc-channels.c.
2953 * Added SilcClientStatus field to the SilcClientEntry in the
2954 lib/silcclient/idlist.h.
2956 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2957 is incomplete and is being resolved, it won't be resolved
2960 Make sure also that USERS command reply does not resolve
2961 twice information. Affected file is
2962 lib/silcclient/command_reply.c.
2964 Make sure that silc_client_get_clients_by_list does not
2965 resolve twice same information.
2967 * Check for valid client->id in the silc_server_free_client_data.
2968 Affected file silcd/server.c.
2970 * Fixed /GETKEY nick@server not to crash if the server entry
2971 is not found. Affected file lib/silcclient/command.c.
2973 * Fixed the silc_server_check_cmode_rights to check the
2974 requested modes correctly. Affected file silcd/command.c.
2976 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Better checks for non-printable chars in nick added.
2979 Affected file silcd/command.c.
2981 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Call the silc_server_udpate_servers_by_server in the
2984 primary router that comes back online in the backup resuming
2985 protocol. Otherwise it routes packets wrong. Affected file
2986 silcd/server_util.[ch], silcd/server_backup.c.
2988 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2991 lib/silcutil/silcbuffmt.[ch].
2993 * Redefined the SILC packet header to include the padding
2994 length. Affected file lib/silccore/silcpacket.[ch].
2996 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2997 length for maximum padding up to 128 bytes). Affected
2998 file lib/silccore/silcpacket.h.
3000 * Removed all backwards support for old 0.5.x MAC thingies.
3001 The SILC packet header change makes it impossible to be
3002 backwards compatible.
3004 * Send the ENDING packet with timeout in the backup resuming
3005 protocol. This is to assure that all routers has connected
3006 to the primary router. Affected file silcd/server_backup.c.
3008 * Changed the RNG to take the first IV from random data. It
3009 used to take it from zero actually. Changed the RNG also
3010 to use /dev/urandom during session. /dev/random is used
3011 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3013 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Changed the SILC packet header to have the first two bytes
3016 (the packet length) encrypted. Affected files aroung the
3017 code tree, lib/silccore/silcpacket.[ch]. Removed the
3018 SilcPacketCheckDecrypt callback. It is not needed anymore
3019 since the silc_packet_receive_process will determine now
3020 whether the packet is normal or special.
3022 * Implemented the unidirectional MAC keys. Affected files
3023 lib/silcske/silcske.c, silcd/protocol.c and
3024 lib/silcclient/protocol.c.
3026 * Implemented the packet sequence number to the MAC computation.
3027 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3028 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3029 lib/silcclient/protocol.c.
3031 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Allow backup router to announce servers. All servers
3034 announced by backup router are added to the global list
3035 automatically. Update hte server's socket to our primary
3036 router also when backup router announces a server.
3037 Affected file silcd/packet_receive.c.
3039 * Do not update the client->router in the function
3040 silc_server_udpate_clients_by_server if the client is on
3041 global list. We might fail to find any specific server
3042 for locally connected clients and local cell clients. They
3043 should still use the `from' and not `to' as client->router.
3044 This fixes backup router resuming protocol. Affected file
3045 silcd/server_util.c.
3047 * Decrease channel statistics count only if the channel
3048 deletion worked. Affected files are silcd/server.c and
3049 silcd/server_util.c.
3051 * Added silc_server_update_servers_by_server to update origin
3052 of all server entries. Used during backup router protocol.
3053 Affected files silcd/server_util.[ch], silcd/server.c. and
3054 silcd/backup_router.c.
3056 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3057 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3058 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3059 lib/silccrypt/silchmac.c.
3061 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Assure that router cannot reroute the same channel message
3064 to the sender. Affected file silcd/packet_receive.c.
3066 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Made better checks that the channel message is not sent
3069 to the router it came from. Affected file is
3070 silcd/packet_send.c. Fixed memory leak too.
3072 * Announce informations for incoming router connection, but
3073 only after checking if it is replaced by backup router.
3074 Affected file silcd/packet_receive.c.
3076 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Fixed the backup resuming protocol to work in multiple
3079 router environment. Affected file silcd/server_backup.c.
3081 * Route packet only to one router in the function
3082 silc_server_packet_send_to_channel. Affected file is
3083 silcd/packet_send.c.
3085 * Fixed silc_server_send_notify_dest to set the broadcast
3086 flag. Fixed the silc_server_send_notify_topic to actually
3087 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3088 Affected file silcd/packet_send.c.
3090 * Changed the SFTP Filesystem interface. Changed the
3091 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3092 the filesystem operation function. The SilcSFTPFilesystem
3093 is now a context that is allocated by all filesystem allocation
3094 functions and it already includes the operations structure
3095 and filesystem specific context. It is given as argument
3096 now to the silc_sftp_server_start. This made the interface
3097 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3098 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3100 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Changed the backup router adding and getting interfaces
3103 in the server. The router that will be replaced by the
3104 specified backup router is now sent as argument. Affected
3105 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3108 * Added silc_net_addr2bin_ne to return the binary form of
3109 the IP address in network byte order. Affected files
3110 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3112 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Check for existing server ID in silc_server_new_server
3115 and in silc_server_connect_to_router_final and remove the
3116 old entry if it exists. Affected file silcd/packet_receive.c,
3119 * Send the channel message always to only one router, either
3120 in upstream or downstream. Affected file is
3121 silcd/packet_send.c.
3123 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Wrote the definition of the backup resuming protocol to the
3126 protocol specification.
3128 * Removed one redundant channel key generation from normal
3129 server during joining procedure. Removed one redundant
3130 channel key sending from server to router during joining
3131 procedure. Affected file silcd/command.c.
3133 * Made minor bugfixes to the backup router resuming protocol.
3134 Affected file silcd/server_backup.c, server.c.
3136 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Added --disable-asm configuration option. Affected files
3139 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3142 * Implemented the backup resuming protocol that is used to
3143 resume the primary router position in the cell after the
3144 primary router comes back online. Affected files
3145 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3146 and silcd/server_util.[ch].
3148 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Sleep two (2) seconds after sending QUIT command to server.
3151 Affected file lib/silcclient/command.c.
3153 * Assure that if outgoing data buffer is pending do not force
3154 send any data. Affected file silcd/packet_send.c.
3156 * Assure that if outgoing data buffer is pending do not force
3157 send any data. Affected file lib/silcclient/client.c.
3159 * Implemented the backup router support when the primary router
3160 goes down. The servers and routers can now use the backup
3161 router as new primary router without loosing connectivity.
3163 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3166 in the server to indicate disabled entry. All data read
3167 from the connection will be ignored and no data is sent
3168 for entry that is disabled. Affected files are
3169 silcd/idlist.h, silcd/server.c.
3171 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Created SFTP client and server test programs in the
3174 lib/silcsftp/tests directory.
3176 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Implemented memory filesystem (virtual filesystem) for
3179 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3182 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Implemented the SFTP (SSH File Transfer Protocol) to the
3185 lib/silcsftp. It includes SFTP client and SFTP server
3188 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Moved lib/silccore/silcprotocol.[ch] to the
3191 lib/silcutil library.
3193 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3194 take variable argument list pointer as argument. Affected
3195 file lib/silcutil/silcbuffmt.[ch].
3197 * Added silc_buffer_set function that is used to set data
3198 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3199 Affected file lib/silcutil/silcbuffer.h.
3201 * Changed various routines in the core library to use the new
3202 silc_buffer_set instead of allocating new buffer only for
3205 * Added 64-bit value formatting and unformatting support to the
3206 silc_buffer_[un]format routines. Affected file is
3207 lib/silcutil/silcbuffmt.[ch].
3209 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3210 to includes/bitmove.h.
3212 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Fixed channel user mode saving in client library. Affected
3215 file lib/silcclient/command[_reply].c.
3217 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Defined the file transfer to the SILC Protocol. Added
3220 new packet type SILC_PACKET_FTP and defined File Transfer
3221 Payload. The mandatory file transfer protocol is SFTP
3222 (SSH File Transfer Protocol). Affected file in addition
3223 of the internet draft is lib/silccore/silcpacket.h.
3225 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3226 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3227 is used as part of backup router protocol when the primary
3228 router of the cell is back online and wishes to resume
3229 the position as primary router.
3231 * Redefined the MAC generation keys in the protocol. The
3232 same key is not used anymore in both direction. Both
3233 direction will now use different keys for sending and
3234 receiving. This fixes a potential security flaw. This
3235 change causes incompatibilities in the protocol.
3237 * Redefined also the MAC computation from the packet.
3238 An packet sequence number is now added to the MAC
3239 computation. This prevents possible replay attacks against
3240 the protocol. This change too causes incompatibilities
3243 Added `sequence' field to the SilcPacketContext to hold
3244 the current sequence number for the packet.
3246 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * Added `created' field to the SilcIDListData in the file
3249 silcd/idlist.h to indicate the time when the entry was
3252 * Added `created' field to the SilcChannelEntry too. Affected
3253 file silcd/idlist.h.
3255 * Added `creation_time' aguments to all the announcement functions
3256 in the server. If it is provided then only the entries that
3257 was created after the provided time frame are actually
3258 announced. Affected file silcd/server.[ch].
3260 * The protocol says that the Channel ID's IP address must be
3261 based on the router's IP address. Added check for this in
3262 the silc_server_new_channel when processing incoming New Channel
3263 Payload. Affected file silcd/packet_receive.c.
3265 * Print out the correct version with --version in SILC client.
3266 Affected file irssi/src/silc/core/silc-core.c.
3268 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Fixed WHOWAS command to check for completnes of the client
3271 entry always, not just when the command is coming from client.
3272 Affected file silcd/command.c.
3274 * Added new function silc_server_packet_queue_purge to purge the
3275 outgoing data queue to the network. After the function returns
3276 it is guaranteed that the outgoing packet queue is empty.
3277 Affected file silcd/packet_send.[ch].
3279 * Purge the outgoing packet queue in the rekey protocol's final
3280 callback to assure that all rekey packets go to the network
3281 before quitting the protocol. Affected file silcd/server.c.
3283 * Added silc_client_packet_queue_parse as similar function as
3284 in server to the client library. The affected file is
3285 lib/silcclient/client.c.
3287 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Splitted silcd/server.c and created silcd/server_util.[ch]
3290 for utility functions.
3292 * Added new socket flag SILC_SF_DISABLED to indicate that the
3293 connection is open but nothing can be sent to or received from
3294 the connection. Affected file lib/silcutil/silsockconn.[ch].
3295 The checking for disabled socket is checked in the low level
3296 silc_socket_write and silc_socket_read functions.
3298 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * Allow only nicknames and channel names that fits into the
3301 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3303 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * When processing JOIN command reply in server check that if
3306 the channel exists in our global list we'll move it the local
3307 list. Affected file silcd/command_reply.c.
3309 * Fixed the check whether client is joined on the channel already
3310 in JOIN command. Affected file lib/silcclient/command.c.
3312 * Fixed the JOIN command reply to check whether the channel
3313 already exists. Affected file lib/silcclient/command_reply.c.
3315 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Added silc_ske_status_string to map the SKE error numbers
3318 to readable strings. The affected files are
3319 lib/silcske/silcske[_status].[ch].
3321 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3323 * Do not show the private channels on the WHOIS channel list
3324 as it is not allowed by the protocol. The affected file is
3327 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Assure that the packet length digged from the actual packet
3330 is something sensible in the silc_packet_decrypt_rest_special
3331 in lib/silccrypt/silcpacket.c.
3333 * Free and NULL the allocated pointer in silc_hmac_alloc if
3334 the HMAC allocation fails. The affected file is
3335 lib/silccrypt/silchmac.c.
3337 * Print the selected security properties to the log files in
3338 the server. Affected file silcd/protocol.c.
3340 * Add SKE's reference counter even if calling the completion
3341 callback manually. Otherwise it goes negative, although it
3342 does not cause any problems. The affected file is
3343 lib/silcske/silcske.c.
3345 * Remove the client entry with short timeout after giving the
3346 KILL command. Affected file lib/silcclient/command.c.
3348 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3349 case all found clients are already disconnected (WHOWAS would
3350 found them) in the server. Affected file silcd/command.c.
3352 * Update the last_receive (time of last data received) to be
3353 updated only when received private or channel message so that
3354 the idle time showed in WHOIS makes more sense.
3356 * Added boolean field `valid' in to the SilcClientEntry in the
3357 client library to indicate whether the entry is valid or not.
3358 This fixes the nickname change bug on channel when changing
3359 the nickname to be same than the old (like nick to Nick) the
3360 nickname formatter doesn't set the new nick anymore to Nick@host.
3361 Affected file lib/silcclient/idlist.[ch].
3363 * Now actually fixed the nickname changing on disconnection.
3364 Added new function silc_change_nick to the Irssi SILC Client.
3365 Affected file irssi/src/silc/core/client_ops.c,
3366 irssi/src/silc/core/silc-nicklist.[ch].
3368 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Check that the public key exists in the GETKEY command before
3371 trying to encode it. Affected file silcd/command.c.
3373 * Print some notifications on received public keys with GETKEY
3374 command in the Irssi SILC Client. Affected files are
3375 irssi/src/fe-common/silc/module-formats.[ch],
3376 irssi/src/silc/core/client_ops.c.
3378 * Use IDENTIFY command to resolve the server information in the
3379 GETKEY command instead of INFO command. Affected file
3380 lib/silcclient/command.c.
3382 * All command reply functions in the client library now calls
3383 the pending command reply callbacks even if an error has
3384 occurred. The server has done this a long time and now it was
3385 time to move the client library to this as well. Now all
3386 errors can be delivered back to the pending command reply
3387 callbacks if necessary. Affected files are
3388 lib/silcclient/command[_reply].[ch].
3390 * Change the nickname on disconnection back to the username
3391 because in reconnect the server will enforce it to it anyway.
3392 Affected file irssi/src/silc/core/silc-servers.c.
3394 * Fixed a config file parsing bug in the Irssi SILC client.
3395 Affected file irssi/src/silc/core/clientconfig.c.
3397 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * When printing the channel mode on JOIN, verify that the
3400 channel key and channel's HMAC are valid. Affected file
3401 irssi/src/silc/core/client_ops.c.
3403 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3406 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3407 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3409 * Removed channel key rekey task deleting from the function
3410 silc_server_save_channel_key. Affected file silcd/server.c.
3411 Added explicit timeout task context instead that is used to
3412 delete the task if we are registering a new task before the
3413 new task has elapsed.
3415 * When channel key rekey occurs the client library now saves
3416 the old channel key for a short period of time (10 seconds) and
3417 is able to use it in case some is still sending channel
3418 messages encrypted with the old key after the rekey. Affected
3419 file lib/silcclient/[idlist.h|client_channel.c].
3421 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Added check to the silc_server_new_id_real to not accept
3424 new ID if it is the sender's own ID. Affected file is
3425 silcd/packet_receive.c.
3427 * Assure that we do not announce ourself or the one we've
3428 sending our announcements when we're router and are announcing
3429 servers to our primary router. Affected file silcd/server.c.
3431 * Fixed silc_server_command_identify_check_client to assemble
3432 correct WHOIS packet. It send corrupted WHOIS packet and
3433 caused problem with router to router connections. Affected
3434 file silcd/command.c.
3436 Fixed also silc_server_command_whois_check the same way
3437 as for the IDENTIFY command.
3439 * Added new SilcIDListStatus to the server in the SilcIDListData
3440 structure. The status now includes the current status of
3441 the entry (like registered, resolved etc.). Affected file
3442 silcd/idlist.[ch]. Defined a bunch of different status types
3443 as well. This replaced the old boolean registered field as well.
3445 Added resolve_cmd_ident field to the SilcClientEntry structure
3446 too so that if the entry is for example being resolved so
3447 another command may attach to the same pending command reply
3448 without requiring to resolve the same entry again. This concept
3449 should optimize the WHOIS and the IDENTIFY resolving under
3450 heavy load by taking away unnecessary resolving for entries
3451 that are being resolved already.
3453 Added support for adding multiple pending commands for one
3454 command idenfier. Affected file silcd/command[_reply].[ch].
3456 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3457 before deleting the data. Otherwise the hash table will have
3458 freed data in comparison functions. Affected file is
3459 silcd/command_reply.c.
3461 * Fixed silc_idlist_replace_client_id to add the new entry to
3462 the cache with NULL nickname. Otherwise there will be invalid
3463 memory as the nickname after the nickname is freed. Affected
3464 file silcd/packet_receive.c.
3466 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3467 saved into wrong slots because the previous number of entries
3468 was not taken into account. Affected file silcd/idlist.c.
3469 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3471 * If we are router and we receive JOIN notify to a channel that
3472 does not have any users then notified client is marked as the
3473 channel founder, as it is it. The affected file is
3474 silcd/packet_receive.c
3476 * Added to the extended hash table API's table_del_*ext functions
3477 the destructor as argument too, so that the caller can decide
3478 which destructor to use or whether to use destructor at all.
3479 Affected file lib/silcutil/silchashtable.[ch].
3481 * Fixed ID Cache purging. It actually deleted the entries from
3482 the hash table after the data was freed. The hash table ended
3483 up comparing freed memory. The affected file is
3484 lib/silccore/silcidcache.c.
3486 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Fixed Irssi SILC client's KILL command's HELP syntax.
3490 * The USERS command now resolves the detailed user information
3491 if the userinfo field is missing. Affected file is
3492 lib/silcclient/command_reply.c.
3494 * Do not print error in silc_file_read if the read file does
3495 not exist. Just silently return NULL. Affected file is
3496 lib/silcutil/silcutil.c.
3498 * Fixed the silc_log_output to not wine about NULL filename
3499 and to not create some bogus " " filename. Affected file is
3500 lib/silcutil/silclog.c.
3502 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Fixed various printing bugs on the user interface in the
3505 Irssi SILC Client. Minor changes that were forgotten from
3508 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Fixed the configure.in.pre and the compilation and distribution
3511 environment to support the new autoconf 2.52. That version is
3512 now required to compile the CVS trunk.
3514 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3517 to generally parse user@fqdn format strings. Affected file
3518 lib/silcutil/silcutil.c.
3520 * Added nickname_format and nickname_force_format fields to the
3521 SilcClientParams structure. The first one defines the format
3522 for the nicknames that the library will enforce if the receives
3523 multiple same nicknames. The second one is boolean value and
3524 can be used to force the library to always enforce the format
3525 to the nicknames regardles whether there are multiple nicknames
3526 or not. This configurable formatting was employed to flexibly
3527 support accessing multiple nicknames from the user interface.
3528 The userinterface can now set the nicknames to what ever format
3529 they prefer. Affected file lib/silcclient/silcapi.h.
3531 Added function silc_client_nickname_format to the file
3532 lib/silcclient/idlist.c. It performs the nickname formatting.
3534 Added new field `hostname´ to the SilcClientEntry context.
3535 It holds the hostname of the client. Affected file is
3536 lib/silcclient/idlist.h.
3538 * Irssi SILC Client sets the nicknames in nick@hostn format.
3539 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3540 irssi/src/silc/core/silc-core.c.
3542 The WHOIS printing now also shows both the real nickname and
3543 the formatted nickname so that user knows how to access the
3544 user if there are multiple same nicknames cached. Affected
3545 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3546 printing formatting too to take the hostname now as a separate
3547 argument. The Affected file is
3548 irssi/src/fe-common/silc/modules-formats.[ch].
3550 * Changed the silc_client_get_clients_local to accept the formatted
3551 nickname as argument. It accepts the real nickname too but the
3552 formatted nickname can be used to find the true entry from
3553 multiple entries. Affected file lib/silcclient/silcapi.h and
3554 lib/silcclient/idlist.c.
3556 * Added nickname_format_parse field to the SilcClientParams.
3557 It is a callback function provided by the application to parse
3558 the nickname out of the formatted nickname string. The library
3559 calls it to get the nickname from the formatted string. Since
3560 the application generally knows better the format of the nickname
3561 string it parses it instead of the library, even though library
3562 encodes the formatted string. If the callback function is not
3563 provided then the library will use the string as is. The
3564 affected file is lib/silcclient/silcapi.h.
3566 * All the nickname strings passed to the client library in
3567 commands are now expected to be formatted nickname strings.
3568 If the command does not support the formatted nickname string
3569 it will assume that the sent string is the actual nickname.
3570 Affected file lib/silcclient/command.c.
3572 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3574 * Added public key authentication support to OPER and SILCOPER
3575 commands in the client library. Affected file is
3576 lib/silcclient/command.c.
3578 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3580 * Changed the get_auth_methdod client operation to be asynchronous.
3581 It can be async if the application resolves the authentication
3582 method from the server during the negotiation. Added new
3583 SilcGetAuthMeth completion callback that the application will
3584 call after resolving the authentication method.
3586 Added function silc_client_request_authentication_method that
3587 the application can use to resolve the authentication method
3588 from the server. Added also SilcConnectionAuthRequest callback
3589 that the library will call after the server has replied. The
3590 application can call this function if it does not know the
3591 current authentication method.
3593 Affected files are lib/silcclient/client.c and
3594 lib/silcclient/silcapi.h.
3596 * The Irssi SILC client now automatically resolves the authentication
3597 method incase any configuration information is not present (and
3598 currently there never is). The affected file is
3599 irssi/src/silc/core/client_ops.c.
3601 * Fixed public key authentication from the client library.
3602 Affected file lib/silcclient/protocol.c. Changed also the
3603 protocol specification about the public key authentication in
3604 the connection authentication protocol. The actual data to be
3605 signed is now computed with a hash function before signing.
3607 * Fixed the public key authentication from the server as well.
3608 Affected file silcd/protocol.c.
3610 * Removed the mlock()'s from the memory allocation routines.
3611 Affected file lib/silcutil/silcmemory.c. The ./configure does
3612 not check anymore for the mlock(). Affected file is
3615 * Fixed USERS command in server to allow the execution of the
3616 command for private and secret channels if the client sending
3617 the command is on the channel. Affected file silcd/command.c.
3619 * Fixed silc_client_get_clients_local to return the clients
3620 count correctly. It could return wrong value. Affected file
3621 lib/silcclient/idlist.c.
3623 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3625 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3626 types. The assembler optimizations seemed not to like 64-bit
3627 data types. The assmebler optimizations thus are now enabled
3628 also for BSD systems as opposed to only enable them for Linux.
3630 * Do not check for threads at all on BSD systems. Affected
3631 file configure.in.pre.
3633 * Removed -n and -h options from the Irssi SILC Client since
3634 they are not used in silc.
3636 * Fixed the prime generation to assure that the first digit
3637 of the generated random number is not zero since our conversion
3638 routines does not like number strings that starts with zero
3639 digit. If zero digit is seen the random number is regenerated.
3640 This caused some corrupted RSA keys when the zero first digit
3641 was met. Affected file lib/silcmath/silcprimegen.c.
3643 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Fixed WIN32 configuration in the ./configure script.
3646 Fixed to include xti.h on environments that has it.
3647 Patches by Carsten Ilchmann and andrew.
3649 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Changed the silc_id_create_client_id to be collision
3652 resistant. It is now assured that there cannot be created
3653 two same client ID's. I suspect that some weird bugs in
3654 the server were actually caused by duplicate Client IDs.
3655 Affected file silcd/serverid.[ch]. A router receiving
3656 new ID now also assures and informs the sending server
3657 if the ID caused collision.
3659 * Changed the silc_id_create_channel_id to also assure that
3660 there are no collisions.
3662 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Statement about ignoring the Mutual Authentication flag when
3665 performing rekey with PFS was a bit misleading. It is ignored
3666 if it was set in the initial negotiation, it cannot be even
3667 set in the rekey. Fixed in the ke-auth draft. Started the
3668 new versions of the protocol drafts in the doc/.
3670 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Fixed a bug in silc_client_command_identify_save when saving
3673 new channel information. The channel name was no duplicated
3674 and caused crash on exit. Affected file is
3675 lib/silcclient/command_reply.c.
3677 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3679 * Fixed the getkey command handling in the server. Send just
3680 empty OK reply to the sender if the key could not be fetched
3681 (but everything else was ok, like the key just was not available).
3682 Changed the public key parameter to optional in the protocol
3683 specs so that empty OK reply can be sent. Affected file
3686 Added a message to Irssi SILC client to tell to user if the
3687 server did not return a public key.
3689 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Fixed a channel key regeneration bug. It registered new
3692 timeout tasks exponentially until all system resources were
3693 used. Affected file silcd/server.c.
3695 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3697 * Added the SILC Document generator to the scripts/silcdoc.
3698 It can be used to generate the Toolkit Reference Manual out
3699 of the source tree. Internally it will also use the RoboDoc
3700 generator now imported in util/robodoc.
3702 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Added couple of return's in rekey protocol if error orccurred
3705 during the protocol. The execution must be terminated.
3706 Affected file silcd/protocol.c. Also, terminate the protocol
3707 always with timeout.
3709 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3711 * The client's Client ID was created initally from the wrong
3712 nickname (it could have been in format nick@host) in the
3713 silc_server_new_client. Affected file silcd/packet_receive.c
3715 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Added some SILC_LOG_ERROR's to various error conditions
3718 if client could not be added to ID cache. Affected files
3719 silcd/packet_receive.c and silcd/server.c.
3721 * When client's sock->user_data is freed, NULL also the
3722 client->router and client->connection pointers. Added check
3723 for these pointers being NULL to various places around the
3724 code. Affected file silcd/server.c.
3726 * Added client->data.registered == TRUE checks to various
3727 places around the code to assure that unregistered client's
3728 are not handled when it is not allowed. Affected file
3731 * Added `bool registered' fields to all
3732 silc_idlist_[server|client]_get_* routines to indicate whether
3733 the fetched client needs to be registered or not. Affected
3734 file silcd/idlist.[ch].
3736 * Add your own entry as registered to the ID cache in the
3737 server. Affected file server.c.
3739 * Fixed a bug in silc_server_new_server. The SilcServer was
3740 set as the new server's context instead of SilcServerEntry.
3741 This naturally caused some weird bugs.
3743 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Do not delete the channel rekey task when adding it
3746 for in silc_server_create_channel_key.
3748 * Changed the silc_server_create_channel_key to return
3749 TRUE or FALSE to indicate the success of the channel key
3752 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3754 * Fixed MSVC++ project files and added missing files to
3755 Makefiles under win32/.
3757 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Do not add TCP_NODELAY flag if the operating system
3760 does not have it defined. Affected files are
3761 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3763 * Fixed buffer overflow from Irssi SILC Client. Affected
3764 file irssi/src/fe-common/core/themes.c.
3766 * Fixed double free in client library in the file
3767 lib/silcclient/client.c when disconnecting from server.
3769 * Applied double free patch from cras to Irssi SILC client.
3770 Affected files irssi/src/core/[modules/expandos].c
3772 * Fixed the disconnection handling to Irssi SILC Client.
3773 The application must call silc_client_close_connection
3774 in ops->connect client operation in case of failure of
3775 the connection. Affected file is
3776 irssi/src/silc/core/client_ops.c.
3778 * Do not set sock->protocol to NULL in the function
3779 silc_client_close_connection after executing the protocol's
3780 final callback since the sock might not be valid anymore.
3781 Affected file lib/silcclient/client.c.
3783 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3785 * Do not enable SILC_THREADS if the linking with libpthread
3786 did not happen. Affected file configure.in.pre.
3788 * Added notion to protocol specification that server must
3789 verify the sent authentication payload with CMODE when
3790 setting the channel founder key. Implemented it to the
3791 server. Affected file silcd/command.c.
3793 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Added _EXTRA_DIST SILC distribution variable to the
3796 distributions file. It is used to conditionally add extra
3797 files or directories to the specific distribution. Affected
3798 files ./prepare, Makefile.am.pre and distributions.
3800 Removed the `_' from the start of the distribution names.
3803 * Added README.WIN32 for instructions to compile the Toolkit
3806 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3808 * Fixed a double free in disconnection in the server. Affected
3809 file is silcd/server.c.
3811 * Fixed the lib/silcske/groups.c to work now also with GMP
3812 MP library. The string conversion did not work when using
3813 specific base and the base is indicated in the string as well.
3815 * Created win32/ directory which now includes MSVC++ specific
3816 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3817 It will appear only in the toolkit distribution
3819 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Changed the key material distribution function in case when
3822 the hash output is too short. The data is now concatenated
3823 a bit differently than it used to. Made the change to the
3824 SKE protocol specification.
3826 * Added better GMP detection to configure.in.pre. A patch
3829 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Fixed a minor bug in SKE that might cause some problem on
3832 some platforms. Affected file lib/silcske/silcske.c.
3834 * Added the cookie checking for initiator in the SKE. It checks
3835 that the responder returns the sent cookie unmodified. The
3836 affected file is lib/silcske/silcske.c. Added new SKE
3837 error type INVALID_COOKIE that can be sent during the
3838 negotiation. Fixed some memory leaks as well.
3840 * Added the "invalid cookie" error message to Irssi SILC client's
3843 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3845 * Added `task_max' field to the SilcClientParams to indicate
3846 the maximum tasks the scheduler can handle. If set to zero,
3847 default values are used. Affected file lib/silcclient/silcapi.h.
3849 * Fixed memory leaks in silc_client_close_connection. Affected
3850 file lib/silcclient/client.c.
3852 * Added silc_client_del_client_entry to client library to free
3853 all memory of given client entry. Affected file is
3854 lib/silcclient/idlist.[ch].
3856 * Added new functions silc_client_del_channel and
3857 silc_client_del_server to delete channel and server entries.
3858 Affected file lib/silcclient/[silcapi.h/idlist.c].
3860 * Removed silc_client_del_client_by_id from silcapi.h.
3862 * Fixed the INFO command to return the server's own info
3863 correctly when querying by Server ID. Affected file is
3866 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Removed the non-blocking settings in WIN32 code in the
3869 silc_sock_[read/write] and added SleepEx instead. Affected
3870 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3871 of input data is now checked with FIONREAD and ioctlsocket.
3873 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3875 * Call silc_schedule_task_del_by_context in the
3876 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3877 Affected file lib/silccore/silcprotocol.c.
3879 * Call silc_protocol_cancel for active protocols in the
3880 silc_server_close_connection if the funtion
3881 silc_server_free_sock_user_data has not been called.
3882 Affected file silcd/server.c.
3884 * Generic tasks cannot be deleted using the del_by_fd
3885 task deleting function since generic tasks does not match
3886 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3888 * Added a notion to SILCOPER help file that the SILCOPER works
3889 only on router server, not on normal server.
3891 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3893 * Added for WIN32 support for the new scheduler as well.
3894 Affected file lib/silcutil/win32/silcwin32schedule.c.
3896 * Fixed the SHA1 implementation to work on various platforms.
3898 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3901 API. It is part of the scheduler now. Everything else is
3902 as previously but some functions has changed their names.
3903 Checkout the lib/silcutil/silcschedule.h for the interface.
3904 Updated all applications to use the new interface. Affected
3905 files are lib/silcutil/silcschedule.[ch].
3907 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3909 * Found a bug in the SKE implementation. The HASH value,
3910 specified by the protocol, was not computed correctly. The
3911 public key of the responder was not added to the computation
3912 even though it is mandatory. Affected file lib/silcske/silcske.c.
3913 This unfortunately causes incompatibilities with older
3914 clients and servers.
3916 * Added WIN32 specific network init and uninit functions:
3917 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3918 the Winsock2. Affected file lib/silcutil/silcnet.h and
3919 lib/silcutil/win32/silcwin32net.c.
3921 * Set the socket always to nonblocking mode on WIN32 after
3922 reading data or writing data. Affected file is
3923 lib/silcutil/win32/silcwin32sockconn.c.
3925 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Fixed various compilation problems under WIN32. Affected
3928 files lib/silcutil/win32/silcwin32thread.c and
3929 lib/silcutil/win32/silcwin32schedule.c.
3931 * Removed all _internal.h #includes from public header
3932 files. Internal headers must never be included from
3935 Removed also the lib/silcske/payload_internal.h file.
3937 * All include files that may be needed (public and some others
3938 included by the public headers) by application developers are
3939 now copied to the ./includes directory. It does not copy any
3940 internal headers. Affected file Makefile.defines.pre and all
3941 Makefile.am's under lib/ and subdirs.
3943 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3945 * Do not change the ~/.silc directory's permissions automatically.
3946 Affected file irssi/src/silc/core/clientutil.c.
3948 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Do not cancel the protocol in silc_server_close_connection
3951 it might cause recursion. Now cancelled in the function
3952 silc_server_free_sock_user_data. Affected file silcd/server.c.
3954 * Fixed the silc_server_remove_clients_by_server to regenerate
3955 the channel keys correctly finally. Added also new function
3956 silc_server_remove_clients_channels to actually do it.
3957 Affected file silcd/server.c.
3959 * Fixed the silc_server_new_channel to not crash by giving
3960 wrong router to the new channel. Affected file is
3961 silcd/packet_receive.c.
3963 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3965 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3966 which is given as argument to the silc_client_alloc now.
3967 It can be used to configure the client and set various parameters
3968 that affect the function of the client.
3970 * The USERS command in server did not check whether the channel
3971 is private or secret. Affected file silcd/command.c.
3973 * Added new argument to the USERS command in protocol specification.
3974 The USERS command now can take the channel name as argument
3975 as well. Added support for this in client and server and
3976 updated the protocol specs.
3978 * Completed the GETKEY command in client. It can be now used
3979 to fetch also servers public key not only some clients.
3980 Affected files lib/silcclient/command[_reply].c.
3982 * Added silc_client_get_server to return server entry by the
3983 server name. Affected files lib/silcclient/silcapi.h and
3986 * Redefined the IDENTIFY command in protocol specification to be
3987 more generic. It now can be used to query information about
3988 any entity in the SILC Network, including clients, servers and
3989 channels. The query may be based either the entity's name
3990 or the ID. Added support for this in both client and server.
3992 Affected files silcd/command.c and lib/silcclient/command.c
3993 and command_reply.c.
3995 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3996 the _from_client and _from_server functions. Affected file
3999 * Added silc_client_get_channel_by_id_resolve to the file
4000 lib/silcclient/silcapi.h to resolve channel information by
4001 its ID. Added also silc_client_get_channel_by_id that
4002 does not resolve it from the server.
4004 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4006 * Added SilcServerEntry context into the client library
4007 to represent one server. The INFO command now allocates
4008 these to save the resolved server info. For now on the
4009 client library will also keep information about servers,
4010 connected and resolved with INFO.
4012 The INFO command now allocates the SilcServerEntry context
4013 and saves the server info there. The COMMAND_REPLY in
4014 the INFO now returns the parameters to application in
4015 same order as defined in the protocol specification.
4017 The entries are cached in the client->server_cache.
4019 * The INFO command is now issued after received the Client ID
4020 from the server. Affected file lib/silcclient/client.c.
4022 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4023 to the application as the mode changer might be server.
4024 It is guaranteed that NULL is not returned anymore to the
4025 application. Affected file lib/silcclient/client_notify.c.
4027 The ID Type is now also passed to the application so that
4028 it can check whether the returned entry is SilcClientEntry
4031 Added new function silc_client_get_server_by_id to return
4032 the server entry by ID. Affected files are the
4033 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4035 * Do not create the channel in the Irssi SILC Client when issuing
4036 the JOIN command but when received the sucessful JOIN command
4037 reply. Otherwise the channel might get created even though we
4038 could not join it. The Affected file is
4039 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4041 * Fixed a channel joining bug in router. The router must also
4042 check the channel modes, invite and ban lists etc. when serving
4043 the JOIN command sent by normal server. Affected file is
4044 silcd/command.c. The router now resolves the client's
4045 information from the server who sent the JOIN command if it
4046 does not know it, and processes the JOIN command only after
4049 * Changed the SilcCommandCb to take new argument; void *context2.
4050 Affected file lib/silccore/silccommand.h
4052 The second argument in the command callbacks in the server now
4053 includes the SilcServerCommandReplyContext if the command was
4054 called as pending command callback from the command reply.
4055 Otherwise it is NULL. When called as pending the status of the
4056 command reply will be checked and if it was erronous the
4057 error will be sent to the original sender of the command.
4058 This way the client always receives the error messages even
4059 though the server was actually the one who received the error
4060 when it resent the command to router, for example. Affected
4061 files silcd/command[_reply].[ch].
4063 * Fixed sending WHOWAS command's error message to client if
4064 the requested client could not be found. It was missing.
4067 * Changed the CMODE and CUMODE commands reply arguments in the
4068 protocol specification. The Channel ID is now sent in both
4069 of the commands to identify the channel. Implemented this
4070 new feature to the client and server. Affected files
4071 lib/silcclient/command_reply.c and silcd/command.c.
4073 * Made better checks for invite and ban lists in the JOIN
4074 command in server. Affected file silcd/command.c.
4076 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * The server now performs the incoming host IP/DNS lookup
4079 using the silc_socket_host_lookup and thus does not block
4080 the server anymore. Affected file silcd/server.c.
4082 * Completed the multi-thread support for SILC Scheduler in
4083 the lib/silcutil/silcschedule.c.
4085 * Fixed the configure.in.pre to detect the pthread correctly
4088 * Fixed a deadlock in silc_task_queue_wakeup in the file
4089 lib/silcutil/silctask.c.
4091 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4093 * Added new function silc_schedule_wakeup that is used in
4094 multi-threaded environment to wakeup the main thread's
4095 schduler. It needs to be used when a thread adds a new task
4096 or removes a task from task queues. After waking up, the
4097 scheduler will detect the task queue changes. If threads
4098 support is not compiled in this function has no effect.
4099 Implemented the wakeup mechanism to both Unix and WIN32
4100 systems. Affected files are lib/silcutil/silcschedule.[ch],
4101 lib/silcutil/unix/silcunixschedule.c and the
4102 lib/silcutil/win32/silcwin32schedule.c.
4104 * Added new function silc_task_queue_wakeup to wakeup the
4105 scheduler by the specified task queue. Affected file
4106 lib/silcutil/silctask.[ch].
4108 * The silc_socket_host_lookup_start now wakes up the scheduler
4109 after adding the timeout task. Affected file is
4110 lib/silcutil/silcsockconn.c.
4112 * The silc_socket_host_lookup is synchronous now if the threads
4113 support is not compiled in. However, the callback is still
4114 called asyncronously through the scheduler, anyway. Affected
4115 file lib/silcutil/silcsockconn.c.
4117 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Added new function silc_socket_host_lookup to perform
4120 asynchronous IP and FQDN lookups for the socket connection.
4121 Affected files lib/silcutil/silcsockconn.[ch].
4123 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4126 that may or may not compile the mutex support in.
4128 Changed the silc_mutex_alloc interface. It allocates the
4129 mutex now to the sent pointer and returns TRUE or FALSE.
4131 Affected file lib/silcutil/silcmutex.h.
4133 * Wrote the SILC Task Queue interface to support multi-threads.
4134 Affected file lib/silcutil/silctask.[ch].
4136 * Wrote the SILC Scheduler to support multi-threads. Affected
4137 file lib/silcutil/silcschedule.c.
4139 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4141 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4142 in lib/silcutil/win32/.
4144 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4146 * Defined SILC Mutex API and SILC Thread API and implemented
4147 them for Unix. Affected files are
4148 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4149 lib/silcutil/unix/silcunixmutex.c and
4150 lib/silcutil/unix/silcunixthread.c.
4152 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Fixed the silc_server_remove_clients_by_server's channel
4155 key re-generation. The hash table handling was incorrect
4156 and would not work with many channels. Affected file is
4159 * Fixed some memory leaks around the server code.
4161 * Rewrote the silc_server_get_users_on_channel to support IPv6
4162 based Client ID's. Affected file silcd/server.c.
4164 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4165 specification. However, a separate document must be written
4166 to define the detailed signing procedure and the payload
4167 associated with the flag. Defined the flag to the
4168 lib/silccore/silcchannel.h as well.
4170 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4172 * Changed the dynamic tables to static size tables in the
4173 lib/silccrypt/silchmac.c.
4175 * Removed GCC dependencies from the code. A patch by cras.
4177 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4179 * Do not show the error "Error receiving packet bla bla"
4180 in server if it really was not an error (-2 means that reading
4181 is pending). Affected file silcd/server.c.
4183 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4185 * Fixed a possible crash in silc_server_remove_clients_by_server
4186 in silcd/server.c. Fixed there also some memory leaks.
4188 * Fixed the silc_idlist_replace_client_id. It could replace
4189 wrong key in the hash table. Affected file silcd/idlist.c.
4191 * Do not check whether there are global users on the channel
4192 if the channel->global_users is FALSE. Affected functions
4193 silc_server_remove_from_one_channel and
4194 silc_server_remove_from_channels in silcd/server.c. Also,
4195 do not check if the removed client is local as we can be
4196 sure that global client was not removed from the channel
4197 and checking for global users is not needed.
4199 * The silc_server_remove_clients_by_server now re-generates
4200 the channel keys correctly for those channels that had
4201 clients removed from them. Affected file silcd/server.c.
4203 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Found the reason of random crashes in the server. We weren't
4206 ignoring the SIGPIPE signal (which can be sent in write())
4207 and it crashed the server. Affected file silcd/silcd.c.
4209 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4211 * Assure that sock->user_data is not NULL in the function
4212 silc_server_packet_send in silcd/packet_send.c.
4214 * Disconnect the remote connection if it could not be added
4215 to any ID lists in the server. The affected file is
4218 * Check in silc_server_packet_send[_real/dest] that the
4219 socket is not disconnecting and ignore the data if it is.
4220 Affected file silcd/packet_send.c.
4222 * Define inline to __inline on native WIN32 compilation.
4223 Affected file includes/silcwin32.h.
4225 * Added some explicit type casts for inline code since MSVC
4226 require them. Affected files lib/silcutil/silcbuffer.h,
4227 lib/trq/silcdlist.h and lib/trq/silclist.h.
4229 * Print warning in log files from now on if the packet
4230 decryption fails. Affected file silcd/server.c.
4232 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Changed the `say' client operation's interface to accept
4235 new `type' argument to indicate the type of the message sent
4236 by the library. The application may filter the library's
4237 messages according the type. The affected file is the
4238 lib/silcclient/silcapi.h.
4240 * Added two new functions to lib/silcclient/silcapi.h:
4241 silc_client_del_client and silc_client_del_client_by_id.
4242 Affected file lib/silcclient/idlist.c.
4244 * Moved the clientincludes.h from includes/ to silc/ and
4245 serverincludes.h from includes/ to silcd/.
4247 * The modes for the CMODE and CUMODE are now passed as
4248 uint32 for application with COMMAND_REPLY. The affected
4249 file is lib/silcclient/command_reply.c.
4251 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * /WHOIS without arguments shows client's own information.
4254 Affected file lib/silcclient/command.c.
4256 * Changed PING to not accept any arguments. The specs
4257 says that client can ping only the connected server so
4258 requiring an argument is not needed. Affected file is
4259 lib/silcclient/command.c.
4261 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4263 * Fixed a fatal bug in private message sending and reception
4264 encryption and decryption when using private message keys.
4265 The implementation was incorrect and did not follow the
4266 specification. It causd that some of the message were
4267 lost since it did not use the sending and receiving keys
4268 as the protocol suggests. This has been fixed and will cause
4269 incompatibilities with older clients when sending private
4270 message encrypted with private message keys. Affected files
4271 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4272 and various other in Irssi SILC Client.
4274 Added `responder' boolean argument to the functions
4275 silc_client_add_private_message_key[_ske] to indicate when
4276 the key is added as responder or initiator of the key
4279 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4281 * Removed the silc_ske_check_version function and created
4282 a SilcSKECheckVersion callback. Added also a function
4283 silc_ske_set_callbacks that is now used to set all SKE
4284 callbacks. The callback functions are not given to
4285 the SKE functions anymore, but this function is used to
4288 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4290 * Added `silc_version' argument to the silc_client_alloc
4291 to define the version of the application for the library.
4292 The library will use the version string to compare it
4293 against the remote host's (usually a server) version
4294 string. Affected file lib/silcclient/silcapi.h
4296 * Added the KE protocol context to Key Agreement context
4297 in client library so that we can abort the SKE if it
4298 is in process when we get timeout. Affected file is
4299 lib/silcclient/client_keyagr.c.
4301 * Do not resolve the client ID forever if it returns in the
4302 first time that such client does not exist. This was done
4303 for example with private message. Affected file is
4304 lib/silcclient/client_prvmsg.c.
4306 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4308 * Do not add regex.h for WIN32. The affected file
4309 includes/silcincludes.h.
4311 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4312 not work yet 100%. It generates the DLL's automatically
4313 when compiling with --with-win32 under cygwin.
4315 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4317 * lib/contrib/regex.c is not compiled on WIN32.
4319 * Added silc_net_get_socket_opt function to the
4320 lib/silcutil/silcnet.h.
4322 * Added includes/silcwin32.h for WIN32 specific includes
4325 * Do not use ptime structure or any of the posix process
4326 functions on WIN32 in lib/silccrypt/silrng.c.
4328 * Added silc_gettimeofday to provide generic function
4329 for struct timeval on all platforms. Added the function
4330 to lib/silcutil/silcutil.h.
4332 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4334 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4335 library as they clearly belong there. As a plus side we
4336 can make the actual socket connection routines platform
4339 Added also new generic function silc_socket_read and
4340 silc_socket_write (that used to be silc_packet_[read/write].
4341 The implementation of these are platform specific.
4343 * Added WIN32 specific routines of silc_socket_[read/write]
4344 to lib/silcutil/win32/silcwin32sockconn.c.
4346 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4348 * Added preliminary support for native WIN32 compilation under
4349 cygwin (using the -mno-cygwin option for GCC) to the
4350 ./configure.in.pre. The --with-win32 now prepares the
4351 compilation for native WIN32.
4353 * Rewrote the SILC Scheduler interface in the file
4354 lib/silcutil/silcschedule.h. The scheduler is now context
4355 based and does not have anymore any global static scheduler.
4356 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4357 and created lib/silcutil/win32 directory for WIN32 based
4360 * Added Unix specific network routines to the
4361 lib/silcutil/unix/silcunixnet.c and the old
4362 lib/silcutil/silcnet.c includes now only generic routines.
4364 Added WIN32 specific network routines to the
4365 lib/silcutil/win32/silcwin32net.c.
4367 * Added Unix specific utility functions from the
4368 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4370 * Added WIN32 SILC Scheduler to the file
4371 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4374 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Do not handle JOIN notify in the server if the target client
4377 is not registered (idata->registered == FALSE). The affected
4378 file is silcd/packet_receive.c.
4380 * Update the nickrec->founder in event_cumode in the Irssi SILC
4381 client. Affected file irssi/src/silc/core/silc-channels.c.
4383 * Fixed the CUMODE_CHANGE notify handling in the server when
4384 server and router are announcing their clients on channels.
4385 Now the mode changes are saved and notified correctly. The
4386 affected file is /silcd/packet_receive.c.
4388 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4389 They really did not replace the cache entry in the ID Cache.
4390 Now they do that. Affected file silcd/idlist.c.
4392 * Fixed the KICK notify handling in the Irssi SILC client to
4393 update the channel records so that the kicked client does not
4394 appear to be on the channel. The affected file is
4395 irssi/src/silc/core/silc-channels.c.
4397 * Always update the conn->current_channel when executing command
4398 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4400 * Fixed the KILL notify handling in Irssi SILC client to remove
4401 the killed client on all channels.
4403 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Fixed the silc_parse_command_line to remove extra spaces
4406 from the start and end of the arguments. Affected file is
4407 lib/silcutil/silcutil.c.
4409 * Cancel and free any active protocol in the function
4410 silc_server_close_connection. Affected file silcd/server.c.
4412 * Cancel and free any active protocol in the function
4413 silc_client_close_connction. Affected file is
4414 lib/silcclient/client.c.
4416 * Do not execute the KILL command for clients that are in
4417 history (ie. they are not in the network). Affected file is
4420 * Fixed KILL notify handling, client does not crash anymore.
4421 Affected file irssi/src/silc/core/silc-channels.c.
4423 * Reduced the default packet buffer size from 2048 to 1024 in
4424 lib/silccore/silcpacket.c.
4426 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4427 counter to the SKE context that is incresed when the SKE library
4428 performs async operation outside the library. If the outside
4429 process frees the SKE context and FREED status will be set
4430 and the library will detect after the sync operation that the
4431 libary is freed. The affected files are
4432 lib/silcske/silcske[_status].[ch].
4434 * Resolve the client entry information in the function
4435 silc_client_channel_message to assure that NULL pointer is not
4436 passed as client entry to the application. */
4438 * Fixed the task timeout calculation to assure that there is
4439 never negative timeouts. The affected file is
4440 lib/silcutil/silcschedule.c.
4442 * Fixed the channel user mode notification sending in server.
4443 It was sent point-to-point to the router (or to server by router)
4444 but it needs to be destined to a channel. The routines now
4445 supports sending the channel user mode notifys to the channels
4446 when announcing clients and channels. Affected files are
4447 silcd/server.c and silcd/packet_receive.c.
4449 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4450 It did not actually replace the old channel entry in the cache.
4451 Affected file lib/silcclient/client_notify.c.
4453 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Fixed a possible crash in silc_packet_send_prepare. It now
4456 assures always that there is enough space in the buffer and
4457 at the tail area of the buffer (for MAC).
4459 Fixed the inbound buffer reallocation in silc_packet_read.
4460 It was old code and did not handle the reallocation correctly.
4463 The affected file is lib/silccore/silcpacket.c.
4465 * Fixed buffer overflow in silc_parse_nickname in the file
4466 lib/silcutil/silcutil.c.
4468 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * make install generates new server keys only if there is not
4473 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4476 Added check that if the NOREPLY is set then we will not send
4477 the away message. This avoids infinite loop of away messages
4478 if both clients are away. The affected file is
4479 lib/silcclient/client_prvmsg.c.
4481 * Fixed client crash if /NICK was given without arguments.
4482 Affected file lib/silcclient/command.c.
4484 * Server does not send the invite list in INVITE command back
4485 to the client if the list was not altered. Added this notion
4486 to the protocol spec as well. Affected file silcd/command.c.
4488 Fixed possible crash in INVITE command by checking the
4489 value of silc_server_get_client_route command.
4491 * Fixed the INVITE notify type handling. The arguments are now
4492 taken in correct order and client does not crash. The affected
4493 file is irssi/src/silc/core/silc-channels.c.
4495 Removed the "Inviting xxx to channel" message from the
4496 client library away and let the application handle it.
4497 Affected file lib/silcclient/command.c. Added that message
4498 to Irssi SILC client's message formats.
4500 * Fixed CMODE command crash in client. It now checks the
4501 amount of arguments correctly and does not crash. The affected
4502 file is lib/silcclient/command.c.
4504 * Do not create new channel automatically in silc_channels_join
4505 but check whether the channel by that name already exists.
4506 Affected file irssi/silc/core/silc-channels.c.
4508 * Do not send the SERVER_SIGNOFF to router if the disconnected
4509 entity was the router. Affected file silcd/server.c.
4511 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4512 SILC client as it was missing from there.
4514 Added the handling of the KICK notify to the Irssi SILC client
4515 as it was missing. Added "you have been kicked" message to
4516 Irssi SILC client's message modules formats.
4518 Added the handing of the KILL notify to the Irssi SILC client
4519 as it was missing. Added the kill message module formats
4522 The affected file is irssi/src/silc/core/silc-channels.c.
4524 * The router did not save the channel mode the server announced.
4525 Affected file silcd/packet_receive.c.
4527 * Fixed a possible crash in INFO command in server. If the
4528 server did not provide the server info it crashed. Affected
4529 file silcd/command.c.
4531 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Fixed the GETKEY command in the server to check also the
4534 global list. Otherwise the GETKEY would not work correctly
4535 in normal SILC server. Affected file silcd/command.c.
4537 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Fixed GETKEY crash, it crashed if the command did not succseed.
4541 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4544 is now real and not just an macro interface to GMP.
4546 Removed the entire GMP from the source tree and imported new
4547 NSS MPI library instead. Reason for removing GMP is that it is
4548 extremely large and compiles extremely slow. The NSS MPI
4549 is only a few files and compiles in less than 10 seconds.
4550 The speed is also about the same as GMP. The MPI is imported
4551 to lib/silcmath/mpi.
4553 If the system has GMP installed we will still use the GMP.
4554 If it is not then the NSS MPI will be compiled.
4556 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Merged a long nickname (127 characters long) crash bugfix from
4559 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4561 * Merged a freed memory reference bugfix from Irssi CVS tree.
4562 Affected file irssi/src/core/commands.c.
4564 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Added the server's public key sving and verification to the
4567 server when performing the SKE. This was missing and the
4568 remote server's (or router's) public key was accepted without
4569 checking whether we have it previously or trust it at all.
4570 Affected file silcd/protocol.c.
4572 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Check in the silc_server_timeout_remote if protocol is active
4575 and make sure that the protocol's final callback is called so
4576 that all memory if freed. Affected file silcd/server.c.
4578 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * silc_server_whois_send_reply crashed the server if the nickname
4581 was 127 characters long. Affected file silcd/command.c.
4583 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added sanity check to the silc_server_new_client. If the hostname
4586 is provided inside username then check that the provided hostname
4587 really is the same as the resolved one. If the hostname was not
4588 resolved then check it from the public key. Affected file is
4589 silcd/packet_receive.c.
4591 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4592 if the server disconnected us and the connection is not valid
4593 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4595 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4596 the library to the lib/silcutil/silcutil.[ch].
4598 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Close log file after open. Affected file
4601 lib/silcutil/silclog.c.
4603 * Check whether sock == NULL in silc_client_send_packet and return
4604 if it is. Affected file lib/silcclient/silcclient.c.
4606 * Check rec->entry == NULL in the Irssi SILC Client before
4607 sending the channel message. Affecte file is
4608 irssi/src/silc/core/silc-servers.c.
4610 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Merged a splitted window bugfix from Irssi CVS tree. The
4613 affected file is irssi/src/fe-text/textbuffer-view.c.
4615 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4616 It did not print nickname.
4618 * Improved the distributions system a bit.
4620 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4623 irssi/src/fe-text/gui-window.c.
4625 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4626 to in-active server. The affected file is
4627 irssi/src/silc/core/client_ops.c.
4629 * Resolve the client in USERS command reply if the entry does
4630 not have username resolved. The affected file is
4631 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4632 command to WHOIS command to really resolve stuff. The USERS
4633 is not used any more in any critical section so WHOIS can
4634 be used even though it might be slower than IDENTIFY.
4636 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4639 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Changed the protocol API a bit more consistent in the
4642 lib/silccore/silcprotocol.[ch].
4644 * Changed the following headers to ROBODoc format:
4646 lib/silccore/silcpayload.h
4647 lib/silccore/silcprotocol.h
4648 lib/silccore/silcsockconn.h
4650 All core library headers are now formatted.
4652 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed a bug in Irssi SILC client; do not show that you are
4655 server/router operator if you really are not. Affected file is
4656 irssi/src/silc/core/client_ops.c.
4658 * Renamed silc_command_free_payload to silc_command_payload_free.
4659 Affected file lib/silccore/silccommand.h
4661 * Added silcmath.h to include the prototoypes of various routines
4662 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4665 * Changed the following headers to ROBODoc format:
4667 lib/silccore/silcchannel.h
4668 lib/silccore/silccommand.h
4669 lib/silccore/silcid.h
4670 lib/silccore/silcidcache.h
4671 lib/silccore/silcmode.h
4672 lib/silccore/silcnotify.h
4673 lib/silccore/silcpacket.h
4674 lib/silcmath/silcmath.h
4676 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Added checking to the server code not to start the server if
4679 ciphers and stuff are not configured properly. Affected files
4680 silcd/serverconfig.[h] and silcd/server.c.
4682 * Changed the layout of the header files of the public interfaces
4683 in the SILC libraries. The new layout supports ROBODoc
4684 documentation tool (and some others) so that it is easy to create
4685 a library reference manual. All the other headers and source
4686 code must still follow the CodingStyle document. Also source
4687 code must not include these ROBODoc stuffs, only the headers.
4688 Furthermore, all public interface headers must now be named
4689 by using `silc' prefix, example: silcapi.h, silccipher.h.
4690 Some files were renamed due to this. All the other headers
4691 must not be used as public interfaces. I will update the
4692 CodingStyle document later. Changed following headers, so far:
4694 lib/silcclient/silcapi.h
4695 lib/silccore/silcauth.h
4696 lib/silccore/silcprivate.h
4697 lib/silccrypt/silcdh.h
4699 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Removed silc_client_packet_send_flush from the client library
4704 as it is not needed. Affected file lib/silcclient/client.[ch].
4706 * Added printing of message of unresolved authentication method
4707 to the Irssi SILC client. Added it to the module formats.
4708 Removed the same message from the client library.
4710 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added new distribution feature, DISTLABEL. Every distribution
4713 can define own preprocessor label that can be used in the
4714 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4715 file distributions, acconfig.h.pre and prepare.
4717 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added Makefile.defines_int to include the actual definitions
4720 for Makefile.defines.in. Tested the new distribution system,
4721 created distributions and tested installation.
4723 * Added AWAY message printing to the Irssi SILC client. Added
4724 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4726 * Added SCONNECT command to call the SILC's CONNECT command.
4727 Cannot use CONNECT directly since Irssi uses that internally.
4728 Affected file irssi/src/silc/core/silc-servers.c.
4730 Added ACTION local command. It is same as ME command but takes
4731 the channel as mandatory argument.
4733 Rewrote some of the Irssi's help files to suite for SILC
4736 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added Makefile.defines[.in] that should for now on be included
4739 in all Makefile.am file in the source tree. That file includes
4740 all common compilation definitions for SILC source tree.
4742 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Minor changes to the ./prepare script to change the package
4745 name according the distribution name to the configure.in.
4747 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Created new distribution system. Added file `distributions'
4750 that defines all the distributions that can be created out of
4751 the SILC source tree. The ./prepare script now reads that
4752 file to determine how to prepare the distributions. The
4753 first argument to the ./prepare is the name of the distribution
4754 and second is the version of the distribution. If given
4755 without arguments it creates the default (toolkit) distribution
4756 with the default version (defined in ./prepare).
4758 All Makefile.am files that are subject to the distributions
4759 are now named as Makefile.am.pre. These are ./Makefile.am
4760 and lib/Makefile.am. Others may be changed later.
4762 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Added invite list, ban list, some key management and connection
4765 error message printing to module formats in the Irssi SILC client.
4767 * Added new silc_client_set_away_message to set the away message
4768 that is back to the person who sent private message. The
4769 affected file lib/silcclient/silcapi.h and the
4770 lib/silcclient/client_prvmsg.c.
4772 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Fixed the private message sending in the Irssi SILC client,
4775 added local command KEY to the Irssi SILC client.
4777 Added key management and key agreement message formats to the
4778 irssi/src/fe-common/silc/module-formats.[ch].
4780 Added USERS (alias WHO) printing, server/router operator
4781 indication and LIST command printing to the module formats.
4783 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Fixed channel joining notify handling, cumode notify handling
4786 from Irssi SILC client.
4788 * Added SILC specific module-formats to the Irssi SILC client so
4789 that SILC specific message hilighting, colors etc is possible.
4790 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4792 Added channel mode, channel user mode, actions, notices,
4793 whois and whowas printing to the the module-formats.c.
4795 * Fixed a bug in channel deletion in the server. The channel
4796 is not left to the cache even if the channel founder auth mode
4797 is set when there are no users anymore on the channel. Affected
4798 file silcd/server.c.
4800 * The silc_net_localhost now resolves the entire hostname including
4801 the domain name. Affected file lib/silcutil/silcnet.c.
4803 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Changed the ask_passphrase client operation to be ascynchronous.
4806 It has now a completion callback and a context that the
4807 application must call after it has got the passphrase from
4808 the user. Affected files lib/silcclient/silcapi.h,
4809 lib/silcclient/protocol.c, lib/silcclient/command.c and
4812 Added SilcAskPassphrase callback that the application calls
4813 to deliver the passphrase to the library.
4815 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4816 The public key verification and especially a certificate
4817 verification is asynchronous procedure.
4819 Added new SILC_SKE_STATUS_PENDING status to indicate the
4820 request is pending and a callback will be called to finalize
4823 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4824 indicate that remote end did not send its public key (or
4825 certificate), even though we require it. Added check for this
4826 condition in the SKE. This was a security bug, now fixed.
4828 Defined new SilcSKEVerifyCbCompletion callback that is called
4829 when the verification process is completed.
4831 The affected files lib/silcske/silcske_status.h and
4832 lib/silcske/silcske.[ch].
4834 * Changed the verify_public_key client operation to be async
4835 as well. Defined SilcVerifyPublicKey callback that is used to
4836 indicate the success of the public key verification process.
4838 Changed the server and client to use the new async client
4841 * Changed the Irssi SILC client's internal scheduler to be called
4842 twice as many times as it used to be. As a result the client
4843 should be a bit faster now. Affected file is
4844 irssi/src/silc/core/silc-core.c.
4846 * Added support to Irssi SILC client of asynchronous public key
4847 verification and passphrase inquiry. Affected file is
4848 irssi/src/silc/core/silc-core.c.
4850 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Do not say "You have left channel %s" in client library.
4853 Moved it to the application. Affected files are
4854 lib/silcclient/command.c and silc/client_ops.c.
4856 * Fixed silc_client_get_clients. Command context was not
4857 duplicated and was freed memory in the callback. Affected
4858 file lib/silcclient/idlist.c.
4860 * Do not say "you are now talking..." on JOIN command in the
4861 client library. The appliation must handle it.
4863 * Do not say ".. changed topic to" in command reply in the
4864 client libary. The application must handle it.
4866 * Fixed TOPIC command sending in the client library.
4868 * Fixed a memory leak in silc_client_command_free in the file
4869 lib/silcclient/command.c.
4871 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Imported a modified version of Irssi client to the source tree.
4874 The Irssi will be used to create a new client called
4875 Irssi SILC. Imported to irssi/.
4877 Added silc_core_init_finish function to the Irssi. Affected
4878 file irssi/configure.in.
4880 A lot changes in the Makefile.ams around the irssi tree.
4882 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Do not rehash if the new size is same as the old size of the
4885 hash table, in the silc_hash_table_rehash*. The affected file
4886 lib/silcutil/silchashtable.c.
4888 * Replaced hash_table_del_by_context calls from the server
4889 (when channel->user_list and client->channels) to the
4890 hash_table_del as it is sufficient and faster.
4892 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Added silc_hash_table_list, silc_hash_table_get and the
4895 SilcHashTableList structure to provide an alternative way to
4896 traverse the hash table. The affected files are
4897 lib/silcutil/silchashtable.[ch].
4899 * Changed the server's idlist routines to use the hash table
4900 routines to optimize the code.
4902 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Replaced the client entry's `channel' list and channel entry's
4905 `user_list' list to hash tables for optimized lookup. Changed
4906 the code to use the hash table interface around the code.
4907 Affected file lib/silcd/idlist.[ch].
4909 * Added `auto_rehash' boolean argument to the function
4910 silc_hash_table_alloc to indicate whether the hash table should
4911 auto-rehash when it thinks is appropriate time. It will
4912 increase the hash table size if the there is twice as much
4913 entries in the table than the size of the table, and will
4914 decrease the size if there are twice as less entries than
4915 the size of the table.
4917 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4921 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * silc_idcache_purge_by_context deletes the entry now by context
4924 as it is supposed to do. Affected file lib/silccore/idcache.c.
4926 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4927 client is not anymore valid (WHOWAS givens the info) and not
4928 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4930 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Removed the `data' and `data_len' arguments from the ID Cache
4933 interfaces and added `name' argument. ID Cache does not handle
4934 anymore the binary data only a names associated with given ID.
4936 * When hashing a Client ID with silc_hash_id the entire ID is
4937 not hashed anymore, instead only the hash of the Client ID is
4938 hashed. This way we can access the Client ID from the cache
4939 with Client ID but with the hash of the ID (which is a hash of
4940 the nickname) as well without any difference in performance.
4942 Added also silc_idcache_find_by_id_one_ext to do one on one
4943 searching when we have the actual ID. Added also function
4944 silc_hash_client_id_compare. The affected files are
4945 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4947 * When hashing the name associated with a ID it is always done
4948 in lowercase. This way we can access the cache without worrying
4949 about case-sensitivity, even though, for example nicknames are
4952 * Fixed a bug in server with channel message sending. It put
4953 wrong ID type as destination ID. The affected file
4954 silcd/packet_send.c.
4956 * silc_idcache_del_by_context now deletes from all hash tables
4957 by context. Affected file lib/silccore/idcache.c.
4959 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Changed the client library to use the new ID Cache interface.
4962 Changes around the source tree.
4964 * Added silc_hash_table_rehash_ext to rehash with specific
4965 hash function. Affected file lib/silcutil/silchashtable.[ch].
4967 * Added silc_hash_string_compare to compare two strings in the
4968 hash table. Affected file lib/silcutil/silcutil.[ch].
4970 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Added new function silc_idcache_del_by_context into the
4973 lib/silccore/idcache.[ch].
4975 * Changed the server's ID list routines to use the new ID Cache
4976 interface. Changes around the source tree.
4978 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added silc_hash_table_del[_by_context]_ext functions in to the
4981 lib/silcutil/silchashtable.[ch].
4983 Removed silc_hash_table_find_all* routines and added new
4984 silc_hash_table_find_foreach to replace them.
4986 Added silc_hash_table_replace_ext function as extended
4987 replacing function. Separated the simple hash table interface
4988 from the extended hash table interface in the file
4989 lib/silcutil/silchashtable.h.
4991 * Fixed minor bugs and changed it to use some of the new
4992 hash table functions in lib/silccore/idcache.c
4994 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Added new function silc_hash_table_find_all to return all keys
4997 in the hash table by the specified key. As the hash table is
4998 collision resistant it also makes it possible to have several
4999 duplicate keys in the hash table. This function may be used to
5000 find all of the keys from the hash.
5002 Added user_context arguments to the SilcHashFunction,
5003 SilcHashCompare and SilcHashDestructor to deliver user specified
5006 Added new fuctions silc_hash_table_find[_all]_ext to do
5007 extended lookup with specified hash and compare functions and
5008 specified user contexts.
5010 Added new function silc_hash_table_add_ext to add the key
5011 with specified hash function and user context.
5013 Added new function silc_hash_table_foreach to traverse all
5014 entrys in the hash table. Added SilcHashForeach callback
5017 Added new function silc_hash_table_del_by_context to delete
5018 the entry only if the context associated with the key matches.
5020 Affected files are lib/silcutil/silchashtable.[ch].
5022 * Removed silc_hash_[server/client/channel]_id and added just
5023 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5024 silc_hash_id_compare to compare two ID's using as the hash table
5025 comparison function. Added also silc_hash_data to hash
5026 binary data and silc_hash_data_compare to compare it.
5028 * Removed silc_idlist_find_client_by_hash as it is not needed
5029 anymore. Affected file silcd/idlist.[ch].
5031 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5032 to use internally the SilcHashTable. The new ID Cache is a lot
5033 faster than the old one. Some of the ID Cache interface was also
5034 rewritten and obsolete and stupid functions were removed.
5036 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added entry_count field to the SilcHashTable to keep the number
5039 of the entries in the table. Implemented the function
5040 silc_hash_table_rehash. Added new function
5041 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5043 Fixed a minor bug in silc_hash_table_free.
5045 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5046 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5047 into the lib/silcutil/silcutil.[ch].
5049 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Implemented a collision resistant hash table into the
5052 lib/silcutil/silchashtable[ch]. See the header and the source
5053 for the SilcHashTable API.
5055 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Merged dotconf version 1.0.2 into lib/dotconf.
5059 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Do not compile anything in lib/silcsim/* if the SIM support
5062 is not enabled. The tree should now compile without problems
5065 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Compiled the SILC under cygwin. Compiled and tested briefly
5068 without problems. More tests needed. The SIMs didn't compile
5071 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5073 * Fixed possible crash in silc_get_username in the
5074 lib/silcutil/silcutil.c.
5076 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Fixed a va_arg in silc/client_ops.c.
5080 * Oops, RC5 routines were named AES and caused some problems
5081 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5083 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added new SilcIDIP structure into the lib/silccore/id.h and
5086 replaced the old `ip' fields from all SILC ID's to that type.
5087 This is a step towards IPv6 support.
5089 The silc_id_get_len takes now the ID as an extra argument.
5090 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5091 both IPv4 and IPv6 based ID's.
5093 The affected files are lib/silccore/id.[ch] and other files
5094 around the tree using these routines.
5096 * Removed the ID length arguments in server from various
5097 silc_server_send_notify_* routines -> they are not needed
5100 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed memory leak in silc_encode_pem_file in the file
5103 lib/silcutil/silcutil.c.
5105 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Check minor version as well in the SKE. Affected files are
5108 silcd/protocol.c and lib/silcclient/protocol.c.
5110 * Added --identifier option to the server so that an identifier
5111 can be when creating the public key for the server. Affected
5112 file is silcd/silcd.c.
5114 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5115 lib/silccrypt/silcpkcs.c.
5117 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Register default ciphers and stuff when using -C option with
5120 the server. Affected file sildc/silcd.c.
5122 * Put back the servers public key filename format, it is better
5123 than the new one. For now, the client keys are saved with the
5124 new filename format. The affected file silc/client_ops.c.
5126 * Implemented the Cipher API for the rest of the ciphers that
5127 did not implement it or implemented it the wrong way.
5129 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Register default ciphers and stuff when using the -S option
5132 in the client. Affected file silc/silc.c. Same also when
5133 creating new key pair with -C option.
5135 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Fixed the silc_verify_public_key client operation function to
5138 save the public keys differently. The fingerprint is now
5139 used as filename and not the hostname. This way also the
5140 client keys are saved uniquely and not with hostnames. The
5141 affected file is silc/client_ops.c.
5143 * Trimmed the silc_hash_fingerprint function to remove extra
5144 whitespaces from the end of the fingerprint. The affected
5145 file is lib/silccrypt/silchash.c.
5149 * Added silc_cipher_register_default function to register all
5150 default ciphers. It can be used when configuration files
5151 does not exist and the application does not want any specific
5152 ciphers in any specific order.
5154 The SilcDList is now used as silc_cipher_list dynamically
5155 allocated cipher list. Removed the static list all together
5156 and now all ciphers must be allocated to the dynamic list.
5157 The silc_cipher_alloc routine was changed to check only the
5160 All silc_cipher_* routines that used to return int returns
5163 The affected files lib/silccrypt/silccrypt.[ch].
5165 * The same thing was done to silc_hash_* as for silc_cipher_*
5166 routines. Affected files lib/silccrypt/silchash.[ch].
5168 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5169 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5170 Added also silc_pkcs_[un]register[_default] functions.
5171 Removed the data_context from the PKCS API.
5173 * Added silc_hmac_register_default function to register default
5174 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5175 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5176 to unregister all hmacs at once.
5178 * Register the default ciphers, hash functions, PKCSs and HMACs
5179 if client's configuration file does not exist. The affected
5182 * The client did not load the hash functions from the SIM
5183 modules at all. Added support for this. Affected file is
5184 silc/clientconfig.c.
5186 * When decoding public key with silc_pkcs_public_key_decode, check
5187 the supported algorithm only if PKCS are registered. Affected
5188 file lib/silccrypt/silcpkcs.c. The same was done with the
5189 silc_pkcs_private_key_decode.
5191 * Fixed the SILC List routines to keep the list always in order.
5192 It used to change the list's order when traversing the list but
5193 not it preserves the order. Affected file lib/trq/silclist.h.
5195 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added the client library to use the SilcSocketConnection's
5198 reference counter (by silc_socket_dup) to prevent the bug that
5199 the socket object may be freed underneath async operation.
5201 * The name resolv library checking fixes in the configure.in.pre.
5204 * Created new version of the protocol drafts for future
5205 development. The -03 drafts are the ones that will be changed
5206 in the trunk now and the -02 will remain as they are.
5208 * Send list of CUMODE notifys to the router when announcing
5209 the channel users to the router. Affected file silcd/server.c.
5210 If the router receiving channel founder CUMODE for a channel
5211 that already has channel founder it will send CUMODE notify
5212 to the sender to remove the channel founder rights from the
5213 announced client. Affected file silcd/packet_receive.c.
5215 * The CUMODE notify may now use Server ID as well as the entity
5216 who changes the mode. Updated protocool specs.
5218 * Updated INSTALL and README files.
5220 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5222 * New web pages in the http://silc.pspt.fi. The pages was
5227 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Implemented the [DenyConnectin] config section in the server.
5230 Added silc_server_config_denied_conn to check whether incoming
5231 connection is denied. Affected file silcd/serverconfig.[ch].
5233 * Do not check the ports when checking the incoming configuration
5234 data if the port is 0, meaning any. Affected file is
5235 silcd/serverconfig.c.
5237 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Fixed buffer overflow in silc_string_compare in the file
5240 lib/silcutil/silcutil.c.
5242 * Fixed double free in silc_server_command_leave in the file
5245 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Fixed the version checking in the server. Affected file is
5250 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Fixed the configuration data fetching when accepting new
5253 connections in the server. Affected file silcd/server.c.
5255 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Added `sender_entry' argument to the function
5258 silc_server_packet_relay_to_channel so that we can check
5259 whether some destination actually belongs to the same route
5260 the sender belongs (ie, we must not resend the packet to the
5261 sender). Affected file silcd/packet_send.[ch].
5263 * Added `servername' field to the SilcClientEntry in the server
5264 to hold the name of the server where client is from. Affected
5265 file is silcd/idlist.h.
5267 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Moved the channel message encrypting in the router betwen
5270 router connections from silc_server_channel_message to the
5271 silc_server_packet_relay_to_channel since we want to check
5272 whether we have anybody channel before encrypting anything.
5273 Affected files silcd/packet_[receive/send].c.
5275 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Fixed the [AdminConnection] server config section to support
5278 multiple entries. Affected file silcd/serverconfig.c.
5280 * Added support into the server to check the validity of the
5281 incoming connection before executing any KE or authentication
5284 * The connection configuration is now saved to the KE and
5285 connection auth protocol contexts and not fetched anymore in
5286 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5288 * The local hosts listenning address and port is also resolved
5289 now when starting the server. We want to have the socket object
5290 to include the real address and port for the listener. Added
5291 new function silc_net_check_local_by_sock into the files
5292 lib/silcutil/silcnet.[ch].
5294 * Fixed a broadcast bug in server -> do not broadcast if we
5297 * Fixed a routing bug. Do not route broadcast packets ever.
5298 Broadcast packets must be processed always and not routed since
5299 they may be destined to some other host than yourself and thus
5300 would get routed without no good reason. Affected file is
5303 * Added function silc_server_config_is_primary_route to check
5304 whether primary router connection has been configured (a router
5305 configuration that we are initiating). If there is not, we
5306 will assume that there is only two routers in the SILC network
5307 and we will use the incoming router connection as our primary
5308 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5310 * Changed the order of the broadcasting. Broadcast _after_ the
5311 packet has been processed not before. Affected file is
5314 * Fixed a [ClientConnection] parsing bug. The port was never
5315 parsed correctly thus resulting to port 0. Affected file
5316 silcd/serverconfig.c.
5318 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5319 argument and did not set the broadcast packet flag. Affected
5320 file silcd/packet_send.c. Fixed same bug in the function
5321 silc_server_send_notify as well.
5323 * If we receive NEW_ID packet for our own ID in the server, ignore
5326 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * Removed the nickname from the Private Message Payload.
5331 Updated the code and the protocol specs.
5333 * Updated protocol specs for submitting to the IETF.
5335 * Tweaked the Random Number Generator a bit. Affected file
5336 lib/silccrypt/silcrng.c. Exported a new function
5337 silc_rng_[global]_add_noise which can be used to add more
5340 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Do not parse packets with different timeout when protocol
5343 is active -> may cause problem with rekey. Affected file
5346 * When server receives signoff notify it must not create
5347 new channel key if the client is on any channels since the
5348 sender of the signoff notify will create it.
5350 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added printing of error messages during SKE protocol from the
5353 failure packet sent by server during SKE. Affected file
5356 * Removed the client's failure_callback handling with timeout
5357 and handle it immediately when received.
5359 * The SKE library returned wrong type in SUCCESS and FAILURE
5360 packets. They must be 32 bit MSB not 16 bit MSB.
5362 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Ok, rewrote the logic of the re-key and now it seems to work.
5365 I tested it on high traffic with frequent re-keys without
5366 problems. Added hmac_receive (and renamed hmac to hmac_send)
5367 in SilcClientConnection in lib/silcclient/client.h and
5368 in SilcIDListData in silcd/idlist.h. Also, removed the
5369 SilcPacketParserContext's cipher and hmac fields as they are
5370 not needed anymore and actually caused some problems when
5371 the ciphers and hmac's changed underneath the packet parser.
5373 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * If re-key protocol is active then process the incoming packets
5376 synchronously since we must assure that icoming packets encrypted
5377 with the old key is processed before the new keys is set to
5378 use. This is true other packets than for REKEY packets.
5379 Affected file silcd/server.c. The same was done to client library
5380 as well, affected file lib/silcclient/client.c.
5382 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Fixed bug in client and server to accept the force send if
5385 the packet is send from silc_[server/client]_packet_process
5386 function. Otherwise the packets are never delivered, oops.
5388 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Disable force sending of packets when REKEY protocol is active.
5391 We must assure that no packet is sent directly when rekey is
5392 performed. All packets must be sent through packet queue.
5393 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5394 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5395 function is silc_[server/client]_packet_send_real to check
5398 * Replaced the SIM paths from example config files to
5399 /usr/local/modules. Also, make install creates now
5400 /usr/local/silc/logs directory to hold all the SILC server
5403 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Made the configure.in.pre work on Solaris. Patch by salo.
5407 * Made all ciphers compatible with non-x86 machines. Defined
5408 CBC mode macros into lib/silccrypt/ciphers_def.h.
5410 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Fixed the make install.
5414 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * When MAC computation fails the silc_packet_decrypt returned 0
5417 even though it was supposed to return -1. Fixed this. The
5418 affected file is lib/silccore/silcpacket.c.
5420 * Do not replace the config files in /etc/silc (in make install)
5421 if they already exist. Affected file ./Makefile.am.
5423 * Do not send re-key packets immediately but through packet queue.
5424 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5426 * Changed silc_net_check_host_by_sock to return FALSE if the
5427 IP/DNS could not be resolved. Though, it returns the IP address
5428 now even if it could not resolve it (but returns also FALSE).
5429 Affected file lib/silcutil/silcnet.[ch].
5431 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Added silc_pkcs_decode_identifier to decode the public key's
5434 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5435 Added also silc_pkcs_free_identifier. Added also new context
5436 SilcPublicKeyIdentifier.
5438 * Added -S option to the silc client. It is used to dump the
5439 contents of the specified public key file.
5441 * Changed the PKCS api to return the public key length when
5442 setting the public key.
5444 * Fixed a fatal bug in the public and private key file loading.
5445 Affected file lib/silccrypt/silcpkcs.c.
5447 * Execute the packet parsing for client with zero (0) timeout
5448 if the protocol is active. Affected file silcd/server.c.
5450 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Made the key generation options to the silcd program. Added
5453 -C option, equivalent to client's option.
5455 * Added new [ServerKeys] config section to the server. It
5456 configures the server's public and private key.
5458 * Defined generic Public Key Payload into the protocol
5459 specification to send specific type of public keys and
5462 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5463 public key or certificate.
5465 * Implemented the GETKEY command to the server and to the
5466 client library and on user interface.
5468 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Made preliminary `make install' work.
5472 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Added SilcServerRekey context into silcd/idlist.h.
5476 * Added the PFS support as defined in the specification to the
5477 SKE protocol. Affected files lib/silcske/*.c.
5479 * Added `ske_group' field to the SilcServerRekey context to hold
5480 the number of the SKE group that is used with PFS in re-key.
5481 Affected file silcd/idlist.h.
5483 * Added PFS re-key support to the server. Affected file is
5486 * Added silc_protocol_cancel to cancel execution of the next
5487 state of the protocol. Affected file is
5488 lib/silccore/silcprotocol.[ch].
5490 * Added the re-key support with and without PFS to the client
5491 library. Re-key is performed once in an hour, by default.
5493 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5494 Added silc_client_rekey_callback and silc_client_rekey_final.
5495 Affected files are lib/silcclient/protocol.[ch] and
5496 lib/silcclient/client.[ch].
5498 * Removed the `hmac_key' and `hmac_key_len' fields from the
5499 SilcClientConnection structure; not needed. Affected file is
5500 lib/silcclient/client.h.
5504 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Do not ask whether user wants to use the negotiated private key
5507 for private messages, just use it. Affected file is
5508 silc/local_command.c.
5510 * Added `send_enc_key' and `enc_key_len' fields to the
5511 SilcIDListData structure since they are needed in the re-key
5512 phase. Affected file is silcd/idlist.[ch].
5514 * Implemented the simple re-key protocol into the server.
5515 Affected files silcd/server.c and silcd/protocol.[ch]. The
5516 re-key will be performed once in an hour, by default.
5518 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5519 Added silc_server_rekey, silc_server_rekey_callback and
5520 silc_server_rekey_final.
5522 * Removed Tunneled flag from the protocol. Updated the code
5523 and the specifications.
5525 * Adde `pfs' field to the SilcIDListData to indicate whether
5526 the PFS is to be performed in the re-key. Affected file is
5529 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5532 int64 of at least the xintXX size. If void * is less that 4
5533 bytes uint32 * will be used. Defined bool as boolean.
5535 * Changed _ALL_ unsigned long and unsigned int to uint32,
5536 unsgined short to uint16 in the source tree.
5538 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5539 not handle clients that has entry->data.registered == FALSE.
5540 They are not in the network anymore. Affected file is
5543 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Implemented the sending of the SERVER_SIGNOFF notify in the
5546 server. Affected file is silcd/server.c.
5548 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5549 Added also silc_notify_payload_encode_args into the
5550 lib/silccore/silcnotify.[ch].
5552 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5553 Affected file silcd/packet_receive.c.
5555 * Implemented the SERVER_SIGNOFF notify handling in the client
5556 library. Affected file lib/silcclient/client_notify.c. Also,
5557 implemnted the printing of the SERVER_SIGNOFF info to the
5558 application. Affected file silc/client_ops.c.
5560 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5561 if the deleting was successful. Affected file silcd/idlist.[ch].
5563 * Added support for public key authentication in the connection
5564 authentication protocol in the client library. Affected file
5565 lib/silcclient/protocol.c.
5567 * Changed the server's silc_idlist_get_clients_by_* interface
5568 to support already allocated array so that new entries may be
5569 added to pre-allocated array. Affected file silcd/idlist.[ch].
5570 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5571 and command replies.
5573 * All command reply functions in the server now calls the
5574 pending command callback even if error occured. This way the
5575 error will be delivered to the client as well. Affected files
5576 silcd/command.c and silcd/command_reply.c.
5578 * Fixed INFO command to return local server's info if no server
5579 was provided. Affected file lib/silcclient/command.c.
5581 * Removed RESTART command for good. Updated the code and the
5584 * Rewrote parts of the task system. It is a bit simpler now.
5585 Removed unsued task priorities. The affected files are
5586 lib/silcutil/silctask.[ch].
5588 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Moved the USERS printing from the library to the application.
5591 Affected files lib/silcclient/command.c and silc/client_ops.c.
5593 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added channel key re-key support. The re-key is perfomed
5598 only by the router and is done once in an hour. Added `rekey'
5599 field to the SilcChannelEntry in the server. Affected files
5600 silcd/server.c and silcd/idlist.h.
5602 * Added silc_task_unregister_by_context into the file
5603 lib/silcutil/silctask.[ch].
5605 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added SILC_UMODE_GONE mode to indicate when the client is not
5608 present in the SILC network. Added also support to the local
5609 command AWAY that will set this mode. Added support of showing
5610 "xxx is gone" in WHOIS command. The USERS command shows the
5611 gone status as well.
5613 * Fixed setting server and router operator privileges in the
5614 server's UMODE command. Affected file silcd/command.c.
5616 * Merged the SKE KE1 and KE2 payloads into one payload. The
5617 new KE payload is equivalent to the old KE2 payload.
5619 Cleaned up the SKE Start Payload parsing. It now uses the
5620 simple buffer unformatting to do the parsing. A lot faster
5623 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5624 to the SKE that is used to indicate whether both of the SKE
5625 parties should perform authentication. By default only the
5626 responder performs authentication. By setting this flag also
5627 the initiator must do authentication. By default it is unset
5628 since in normal SKE case, client to server connection, only
5629 the responder should do authentication. When doing SKE between
5630 two clients both should perform authentication. Updated the
5631 code and the protocol specs.
5633 * A little fix to IDENTIFY command in the server. Search the
5634 client first by hash not nickname. Affected file is
5637 * Fixed the silc_client_close_connection to support closing
5638 the client to client connections wihtout deleting too much
5639 data. Affected file lib/silcclient/client.c.
5641 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5642 are received if protocol used to be active but is not anymore
5643 the application would crash due to NULL pointer dereference.
5644 Affected files silcd/server.c and lib/silcclient/client.c.
5646 * Added `hash' field to the SilcClientConnection to include
5647 the hash function negotiated in the SKE protocol.
5649 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5650 to set the channel founder authentication data. A client can
5651 claim the founder rights later by providing the authentication
5652 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5653 This way the channel founder can regain the channel founder
5654 privileges even it is left the channel. This works only on
5655 local server and the client must be connected to the same
5656 server to be able to regain the founder rights. Updated the
5657 protocol specs accordingly.
5659 Added support to the CMODE command in the client to set the
5660 founder auth data. Read the README to see how to set it.
5662 Added support to the CUMODE command to claim the founder
5663 rights. Read the README to see how to do it.
5665 Added support for the founder authentication to the Channel
5666 Entry in the server. Affected file silcd/idlist.h.
5668 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5669 server's CMODE command. Affected file silcd/command.c.
5671 * Added the following new functions into lib/silccore/silcauth.[ch]:
5672 silc_auth_get_method and silc_auth_get_data.
5674 * The server now saves the remote hosts public key to the
5675 SilcIDListData pointer. Affected file silcd/protocol.c.
5677 * The normal server now does not remove the channel entry from
5678 the cache if the founder authentication data is set. It used
5679 to remove it if the founder was the last one on the channel on
5680 the server and left the channel. The auth data is saved and
5681 if the channel is re-joined later the old entry is used with
5682 the old auth data. Affected files silcd/command_reply.c and
5685 * Removed the `pkcs' field from the SilcIDListData structure
5686 in the server; it is not used. Affected file silcd/idlist.h.
5688 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Fixed packet processing on slow links. Partial packets were
5691 never re-processed because the incoming data buffer was cleared
5692 by the application. Application must not directly clear the
5693 sock->inbuf, the packet processing routines handle it. Fixed
5694 this in client library and in server.
5696 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Fixed the WHOIS and IDENTIFY send reply function to really
5699 check whether to send list or just one entry. Affected file
5702 * Cleaned up the LEAVE command's channel key distribution. The
5703 affected file silcd/command.c.
5705 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5706 can enforce the channel mode as well. In that case the ID
5707 includes the ID of the server. The code now enforces the
5708 mode change if the router have different mode than the server.
5710 * The notify client operation with CMODE_CHANGE notify can now
5711 return NULL client_entry pointer if the CMODE was not changed
5712 by client. Application must check for this.
5714 * Added <Server ID> argument to INFO command to support server
5715 info fetching by Server ID.
5717 * Added silc_server_announce_get_channel_users to get assembled
5718 packets of channel users of the specified channel. Affected
5719 file silcd/server.[ch].
5721 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5722 was freed underneath the ID Cache.
5724 * Re-announce clients when the server received CHANNEL_CHANGE
5725 notify from the router. Affected file silcd/packet_send.c.
5727 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5730 crashed since it did not handle the fact that there is no cipher
5731 called "3" and didn't check the error condition. Now fixed.
5733 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5734 flag. It can be used to send message requests.
5736 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Implemented the RESTART command in the client.
5740 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5741 notice type messages. Added notice printing to the user
5744 * The channel keys are not re-generated if the channel's mode
5745 is PRIVKEY, ie private key on the channel exists. Affected
5746 files silcd/server.c and silcd/command.c.
5748 * Fixed a little bug in channel message delivery when channel
5749 private keys are set in the server. Affected file is
5750 silcd/packet_send.c.
5752 * Changed the setting on channel->on_channel = TRUE from the
5753 silc_client_save_channel_key to the JOIN command reply. The
5754 key payload is not received if the private channel key is set.
5755 Affected file lib/silcclient/command_reply.c and the
5756 lib/silcclient/client_channel.c.
5758 * When the CMODE_CHANGE notify is sent and the channel private
5759 key mode is removed the channel key must be re-generated in
5760 other cells as well. Added this support for the router in the
5761 silcd/packet_receive.c.
5763 * Added new local command NOTICE to send notice message on
5764 channel. Affected file silc/local_command.[ch].
5766 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Added new local command ME to the client. It is used to send
5769 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5770 some action. Affected file silc/local_command.[ch].
5772 * Changed channel_message and private_message client operations
5773 to deliver the message flags to the application. Added also
5774 the `flags' arguments to the silc_client_send_channel_message
5775 and silc_client_send_private_message functions. Affected file
5778 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * Redefined the Private Message Payload to support private message
5781 keys and to support the new private message flags. Updated
5782 the protocol specs. Flags makes it possible to have for example
5783 CTCP style messages.
5785 * Added new type SilcPrivateMessagePayload and defined an API
5786 for it in the lib/silcclient/silcprivate.[ch].
5788 * Tested private message private keys successfully. Tested the
5789 private message key set, unset and list commands with the new
5792 * Redefined the Channel Message Payload to include the channel
5793 message flags (equal with private message flags) to support
5794 for example CTCP style messages.
5796 * Defined some of the message (for channel and private message)
5797 flags. Updated the protocol specs and added the flags to the
5798 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5800 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Added SilcKeyAgreementStatus type to the key agreement routines
5803 to indicate the current status and error if one occured.
5804 The status types are defined in the lib/silcclient/silcapi.h.
5806 * Added new local command KEY that is used to set and unset private
5807 keys for channels, set and unset private keys for private messages
5808 with remote clients and to send key agreement requests and
5809 negotiate the key agreement protocol with remote client. The
5810 key agreement is supported only to negotiate private message keys,
5811 it currently cannot be used to negotiate private keys for channels,
5812 as it is not convenient for that purpose.
5814 * Fixed a minor pending callback setting bug in the function
5815 silc_client_get_client_by_id_resolve, now the function works.
5816 Affected file lib/silcclient/idlist.c.
5818 * Added function silc_net_get_local_port to get local bound
5819 port by socket. Added to lib/silcutil/silcnet.[ch].
5821 * Added `sockets' and `sockets_count' fields to the SilcClient
5822 object. They hold the sockets of the listenning sockets in
5823 the client. Listenning sockets may be for example the key
5824 agreement server. Affected file lib/silcclient/client.[ch].
5825 Added functions the silc_client_add_socket and the
5826 silc_client_del_socket. They are exported to the application
5829 * Added ~./silc/clientkeys to support other client's public keys.
5831 * Renamed verify_server_key client operation to verify_public_key
5832 and added one argument to indicate the type of the connection
5833 (server, client etc.).
5835 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added silc_server_connection_auth_request to handle the
5838 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5839 silcd/packet_receive.[ch].
5841 * Added silc_server_send_connection_auth_request into the
5842 silcd/packet_send.c to send the connection auth request packet.
5844 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5847 * Fixed the public key authentication in responder side in the
5848 server. The `auth_data' pointer includes the SilcPublicKey
5849 not the path to the public key. Affected file silcd/protocol.c.
5851 * Implemented the public key authentication in the initiator side
5852 in the server. Affected file silcd/protocol.c.
5854 * Removed the [RedirectClient] config section from the server
5855 configuration. Is not needed and I don't want to implement it.
5857 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Cleaned up the CMODE command in the server. It now works
5860 correctly and supports all the modes defined in the protocol.
5861 Affected file is silcd/command.c.
5863 * Added `hmac_name' field to the SilcChannelEntry in the server
5864 to hold the default HMAC of the channel. It can be set when
5865 creating the channel (with JOIN command). Affected files
5868 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5869 type to indicate the change of the current cipher and hmac
5870 on the channel. Client can safely ignore the <cipher> argument
5871 (if it chooses to do so) since the CHANNEL_KEY packet will
5872 force the channel key change anyway. The <hmac> argument is
5873 important since the client is responsible of setting the new
5874 HMAC and the hmac key into use.
5876 * Fixed the CMODE command in the client library as well.
5878 * Tested CMODE command in router environment successfully.
5880 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Show the version of the remote client (or server) when connecting
5883 to the server. It is logged to the log file. Affected file
5884 is silcd/protocol.c.
5886 * Fixed the KILLED notify handling in the client library. The
5887 client must be removed from all channels when receiving the
5890 Also, do not remove the client entry when giving the KILL
5891 command but when the KILLED notify is received.
5893 * Removed silc_idlist_find_client_by_nickname from the server.
5894 Not needed anymore. Affected files silcd/idlist.[ch].
5896 * Implemented the CHANNEL_CHANGE notify type handling to the
5897 server. Affected file silcd/server.c.
5901 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Added silc_server_send_notify_invite to send the INVITE
5904 notify between routers.
5906 * Implemented the INVITE command correctly to the server.
5908 * Implemented the INVITE notify type handling in the server.
5910 * Implemented the INVITE command to the client library and on the
5913 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added function silc_server_get_client_resolve to find the
5916 client entry by ID from all ID lists and then resolve it
5917 (using WHOIS) if it cannot be found. Affected file is
5920 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Implemented the BAN command to the client library.
5924 * The JOIN command in the server now checks the invite list
5927 * Changed the silc_command_reply_payload_encode_va and the
5928 silc_command_payload_encode_va to support that if argument is
5929 NULL it ignores and checks the next argument. Affected file
5930 lib/silccore/silccommand.c.
5932 * Added silc_server_send_notify_ban to send the BAN notify
5933 type between routers.
5935 * Chaned the silc_notify_payload_encode to support that if
5936 argument is NULL it ignores and checks the next argument.
5937 Affected file lib/silccore/silcnotify.c.
5939 * Tested ban lists in router environment successfully.
5941 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Implemented BAN command to the server, in silcd/command.[ch].
5945 * Removed the BAN and INVITE_LIST modes from the CMODE command
5948 * Added function silc_string_match to regex match two strings.
5949 Affected files lib/silcutil/silcutil.[ch].
5951 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Redefined parts of the SilcChannelEntry in the server to support
5954 the new ban and invite lists.
5956 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Redefined the INVITE command. The same command can be used to
5959 invite individuals to the channel but also to manage the invite
5960 list of the channel (to add to and remove from the invite list).
5961 Updated the protocol specs.
5963 * Added new command SILC_COMMAND_BAN that can be used to manage
5964 the ban list of the channel. Updated the protocol specs.
5966 * Removed the channel modes: the SILC_CMODE_BAN and the
5967 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5968 in the CMODE command. The equivalent features are now available
5969 using INVITE and BAN commands. Updated the protocol specs.
5971 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5972 in the network about change in the current ban list. The notify
5973 type is not used by the client.
5975 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5976 support the invite lists.
5978 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added new function silc_string_regexify that converts string
5981 including wildcard characters into regex string that can
5982 be used by the GNU regex library. Added into the file
5983 lib/silcutil/silcutil.[ch].
5985 Added silc_string_regex_combine to combine to regex strings
5986 into one so that they can be used as one regex string by
5987 the GNU regex library. Added into the file
5988 lib/silcutil/silcutil.[ch].
5990 Added silc_string_regex_match to match two strings. It returns
5991 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5993 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Imported GNU regex to the soruce tree into lib/contrib.
5996 Fixed some compiler warning from the regex.c.
5998 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Fixed MOTD command in the server to work in router environment.
6002 * Fixed the MOTD command in the client library to support
6003 the server argument in the command.
6005 * Added `nickname_len' argument to the silc_idlist_add_client
6006 in the server, as the `nickname' argument may be binary data
6009 * Added silc_idlist_get_channels to return all channels from
6012 * Implemented LIST command to the server. Affected file is
6015 * Implemented the LIST command to the client library and on the
6018 * Added [<user count>] argument to the LIST command reply.
6019 With private channels the user count is not shown.
6021 * Updated TODO and README.
6023 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * The client entry's data.registered must be TRUE even with
6026 global client entry on global client list. The data.registered
6027 is used to check whether the client is anymore in the network,
6028 for example with WHOWAS command so it must be valid.
6030 * Fixed the WHOWAS command in the server. It now actually works
6031 in router environment. Added function into silcd/command_reply.c
6032 silc_server_command_reply_whowas_save.
6034 * Added silc_idlist_purge function to the silcd/idlist.c
6035 to periodically purge the ID Cache.
6037 * Fixed INFO command in the server. It works now in router
6038 environment. Added <server name> argument to the INFO command
6039 reply. Updated the protocol specs.
6041 * Fixed minor bug in silc_idcache_purge to not purge if the
6042 expire value is zero.
6044 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6045 they were buggy because of the WHOWAS information.
6047 * Fixed local command MSG to handle the async resolving of
6048 the remote client properly. It used to fail the first MSG.
6049 Affected file silc/local_command.c.
6051 * Added `data_len' field to SilcIDCache context.
6053 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Update TODO. Todo in commands in the server.
6057 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6060 used by routers as broadcast packet to inform other routers
6061 about the changed user mode.
6063 Implemented the notify handling in the server. Affected file is
6064 silcd/packet_receive.c. Added the function
6065 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6067 * Added new generic Channel Payload and deprecated the New Channel
6068 Payload. The New Channel Payload is now the generic Channel
6071 * Added new argument `mode' to the silc_server_send_new_channel
6072 as it is required in the Channel Payload now.
6074 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6075 and created a new and real SilChannelPayload to represent the
6076 new generic Channel Payload. Implemented the encode/decode
6077 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6079 * Added silc_server_get_client_channel_list to return the list
6080 of channels the client has joined for WHOIS command reply.
6081 Affected file silcd/server.[ch].
6083 * Implemented the channel list sending in the WHOIS command reply
6084 in server and in the client.
6086 Implemented the channel list displaying on the user interface
6087 as well. Affected file silc/client_ops.c.
6089 * Added silc_channel_payload_parse_list to parse list of Channel
6090 Payloads. It returns SilcDList list of SilcChannelPayloads.
6091 Client for example can use this function to parse the list of
6092 channels it receives in the WHOIS command reply. The caller
6093 must free the list by calling silc_channel_payload_list_free.
6094 Affected files lib/silccore/silcchannel.[ch].
6096 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Added one new argument <user mode> to the WHOIS command reply
6099 to return the mode of the user in SILC. Updated the protocol
6102 Implemented it to the server and client.
6104 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Fixed the mode printing on the user interface on joining.
6107 Affected file silc/client_ops.c.
6109 * Implemented the UMODE command and user modes in general to the
6110 client library and to the user interface.
6112 * Implemented the UMODE command to the server.
6114 * The server now sends UNKNOWN_COMMAND error status if client sends
6115 unknown command. Affected file silcd/command.c.
6117 * All server commands now handle the command identifier the right
6118 way when sending the command reply to the client. The client can
6119 use to identify the command replies with the identifier.
6121 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added silc_server_get_client_route to resolve the route to
6124 the client indicated by the client ID. Affected file is
6127 * Added silc_server_relay_packet as general function to relay
6128 packet to arbitrary destination. This deprecates functions
6129 like _send_private_message_key, _relay_notify etc. Affected
6130 file is silcd/packet_send.[ch].
6132 Removed silc_server_send_key_agreement,
6133 silc_server_send_private_message_key and
6134 silc_server_packet_relay_notify functions from the file
6135 silcd/packet_send.[ch].
6139 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6140 server. Affected file silcd/packet_receive.[ch].
6142 * Implemented the KILL command to the client. Implemented the
6143 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6144 Affected files lib/silcclient/command[_reply].c and
6145 lib/silcclient/client_notify.c. Implemented the KILL notify
6146 printing in the user inteface.
6148 * Fixed a lot silc_parse_nick memory leaks from the client
6149 library in the file lib/silcclient/command.c.
6151 * Changed the silc_server_send_notify_on_channels's `sender'
6152 argument from SilcSocketConnection to SilcClientEntry to
6153 check the sender as entry and not as connection object and not
6154 to send to the client provided as argument. The affected file
6155 is silcd/packet_send.[ch].
6157 * The notify packets that are destined directly to the client used
6158 to not to be processed by the server. Now changed that and the
6159 server processes all notify packets. After relaying the packet
6160 to the client the notify packet is processed in the server.
6162 * The silc_server_free_client_data now checks whether there is
6163 pending outgoing traffic for the client and purges the data to
6164 the network before removing the client entry.
6166 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6169 an client is killed from the SILC Network. Updated the protocol
6172 Added new function silc_server_send_notify_killed to the
6173 silcd/packet_send.[ch].
6175 * Added function silc_server_packet_relay_notify to relay notify
6176 packets that are destined directly to a client. In this case
6177 the server does not process the notify packets but merely relays
6178 it to the client. Affected file silcd/packet_send.[ch].
6180 Added also silc_server_packet_process_relay_notify to check
6181 whereto relay the notify. Affected file is
6182 silcd/packet_receive.[ch].
6184 * Implemented the KILL command to the server.
6188 * Added the backup schema desgined last fall to the protocol
6189 specs for everyone to see. The specification is in the
6190 *-spec-xx.txt draft and the packet type definitions for the
6191 backup routers is in *-pp-xx.txt draft. Thusly, added also
6192 new packet type SILC_PACKET_CELL_ROUTERS.
6194 * A big security problem in the implementation discovered. The
6195 signoff of an client did not cause new channel key generation
6196 which it of course should've done. The channel keys must be
6197 always re-generated when client leaves (or signoffs) the channel.
6198 The silc_server_remove_from_channels funtion now handles
6199 the channel key re-generation.
6201 * Added `sender' argument to the silc_server_send_notify_on_channels
6202 to not to send the client provided as argument. Affected file
6203 silcd/packet_send.[ch].
6205 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Implemented OPER and SILCOPER commands into the server and
6210 * Added silc_auth_verify and silc_auth_verify_data to verify
6211 the authentication directly from the authentication payload.
6212 It supports verifying both passphrase and public key based
6213 authentication. Affected file lib/silccore/silcauth.[ch].
6215 * Added `hash' field to the SilcIDListData structure. It is the
6216 hash negotiated in the SKE protocol. Affected file is
6219 * Slight redesigning of the SilcAuthPayload handling routines.
6220 Do not send SilcPKCS but SilcPublicKey as argument.
6222 * Implemented the public key authentication support to the
6223 serverconfig. The public key is loaded from the provided path
6224 and saved as authentication data to void * pointer. Thus,
6225 changed the unsigned char *auth_data to void *auth_data;
6227 * Fixed SHUTDOWN command to send the reply before the server
6228 is shutdown. :) Affected file silcd/command.c.
6230 * Fixed fatal bug in CONNECT command. The hostname was invalid
6231 memory and server crashed. Affected file silcd/command.c.
6233 * Fixed fatal bug in CLOSE command. The server_entry became
6234 invalid but was referenced later in the command. Affected file
6237 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Fixed fatal bug in failure packet handling. Server ignored
6240 the failure and thus crashed when it came.
6244 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6247 that the command may be executed only once in (about) 2 seconds.
6248 The old SILC_CF_LAG flag is same but allows command bursts up
6249 to five before limiting.
6251 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6252 server code. Various commands now includes the CF_LAG_STRICT
6253 flag to disallow any kind of miss-use of the command.
6255 * Fixed the silc_buffer_unformat to not to allocate any data
6256 if the length of the data is zero. It used to allocate the
6257 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6259 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Changed the format of AdminConnection configuration section
6262 in the server. Added username of the admin to the format.
6263 Affected files silcd/serverconfig.[ch].
6265 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6266 to return admin configuration data by host, username and/or
6269 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Implemented WHOWAS command to the server. Added the functions:
6273 silc_server_command_whowas_parse,
6274 silc_server_command_whowas_send_reply,
6275 silc_server_command_whowas_from_client and
6276 silc_server_command_whowas_from_server
6278 * Added <Client ID> argument to the WHOWAS command reply. Updated
6279 the protocol specs accordingly.
6281 * Implemented WHOWAS command and command_reply to the client
6284 Implemented the WHOWAS printing on the user interface.
6286 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Added new argument to the WHOWAS command reply, the real name.
6289 It is an optional argument. Updated the protocol specs.
6291 * Added SilcIDCacheDestructor callback that is registered when
6292 the SilcIDCache is allocated. The callback is called when
6293 an cache entry in the ID Cache expires, or is purged from the
6294 cache. Added into lib/silccore/idcache.[ch].
6296 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6297 to destruct the client entries when the cache entry expires.
6298 Other ID Cache's in server and in the client library ignores
6301 * If the ID Cache entry's `expire' field is zero then the entry
6302 never expires. Added boolean `expire' argument to the
6303 silc_idcache_add function in the lib/silccore/idcache.[ch].
6304 If it is TRUE the default expiry value is used.
6306 * Added silc_server_free_client_data_timeout that is registered
6307 when client disconnects. By default for 5 minutes we preserve
6308 the client entry for history - for WHOWAS command.
6310 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added support to the server to enforce that commands are not
6313 executed more than once in 2 seconds. If server receives
6314 commands from client more frequently, timeout is registered
6315 to process the commands. Affected file silcd/command.c.
6316 Added new function silc_server_command_process_timeout.
6318 * Changed NICK_NOTIFY handling in client library to check that
6319 if the client's nickname was changed, so there is no need to
6320 resolve anything from the server.
6322 * Removed error printing from the WHOIS and IDENTIFY commands.
6323 If error occurs then it is ignored silently in the client library.
6324 The application, however, may map the received error to
6325 human readable error string. The application currently maps
6326 the NO_SUCH_NICKNAME error to string.
6328 * Made the command status message public to the application. Moved
6329 them from lib/silcclient/command_reply.c to
6330 lib/silcclient/command_reply.h. The application can map the
6331 received command status to the string with the
6332 silc_client_command_status_message function.
6334 * Added check to the server to check that client's ID is same
6335 as the Source ID in the packet the client sent. They must
6338 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added dist-bzip hook to the Makefile.am to make bzip2
6341 compressed distributions.
6343 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Server now enforces the maximum length for the nickname and
6346 the channel as protocol specification dictates. 128 bytes for
6347 nickname and 256 bytes for channel name.
6349 * Moved the WHOIS printing to the application. The client libary
6350 does not print out the WHOIS information anymore, the application
6351 must do it. Renamed silc_client_command_reply_whois_print to
6352 the silc_client_command_reply_whois_save.
6354 The client's idle time is also sent to the application now, and
6355 the idle is shown on screen.
6357 * Added silc_client_command_reply_identify_save to save the
6358 received IDENTIFY entries.
6360 * Do not check for channel private keys in message sending and
6361 reception if the channel does not have the PRIVKEY mode set.
6362 Affected file lib/silclient/client_channel.c.
6364 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6367 just surfaced after chaning the JOIN procedure.
6369 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Added silc_client_get_clients_by_list to get client entries
6372 from Client ID list, that is returned for example by JOIN
6373 and USERS command replies. The application should use this
6374 function for example when JOIN command reply is received to
6375 resolve the clients already on the channel (library does not
6376 do that anymore as USERS command reply is not used in the JOIN
6377 procedure anymore). Affected files lib/silcclient/silcapi.h and
6378 lib/silcclient/idlist.c.
6380 * JOIN command reply and USERS command reply returns now SilcBuffer
6381 pointers instead of unsigned char pointers when returning
6382 the client list and mode list.
6384 * Added <Client ID> argument to the JOIN command reply, mainly
6385 for the server to identify for which client the command was
6386 originally sent. Updated protocol specs accordingly.
6388 * Added SilcDlist private_key pointer to the SilcChannelEntry
6389 in the client to support the channel private keys. Affected
6390 file is lib/silcclient/idlist.h.
6392 * Added SilcChannelPrivateKey argument to the function
6393 silc_client_send_channel_message so that application can choose
6394 to use specific private ke if it wants to. If it is not provided,
6395 the normal channel key is used, unless private keys are set.
6396 In this case the first (key that was added first) is used
6397 as the encryption key.
6399 * Implemented the support for channel private key handling.
6400 Implemented the following functions:
6402 silc_client_add_channel_private_key,
6403 silc_client_del_channel_private_keys,
6404 silc_client_del_channel_private_key,
6405 silc_client_list_channel_private_keys and
6406 silc_client_free_channel_private_keys
6408 Affected file lib/silcclient/client_channel.c.
6410 * Added the support for the private keys in the channel message
6411 sending and encryption and in the message reception and
6412 decryption. Affected funtions are
6413 silc_client_send_channel_message and silc_client_channel_message.
6415 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Added SKE's key verify callback to the client library's
6418 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6420 * Removed the statement that server (or router) must send USERS
6421 command reply when joining to the channel so that the client
6422 knows who are on the channel. Instead, the client list and
6423 client's mode list is now sent in the JOIN command reply to the
6424 client who joined channel. This is better solution.
6426 * Added function silc_server_get_users_on_channel and function
6427 silc_server_save_users_on_channel to the silcd/server.[ch].
6429 * Removed function silc_server_command_send_users from the
6432 * Do not show topic on the client library anymore. The topic is
6433 sent in the command reply notify to the application and the
6434 application must show the topic now.
6436 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Added client searching by nickname hash into the IDENTIFY and
6439 WHOIS commands in the server as they were clearly missing from
6440 them. Affected file is silcd/command.c.
6442 * Fixed a bug in private message receiving in the client library.
6443 The remote ID was freed and it wasn't supposed, now it is
6446 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Minor fix to the channel payload; allocate the data area, as it
6449 needs to be of specific length.
6451 * If the key agreement port is zero then the operating
6452 system will define the bound port. Affected files are
6453 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6455 * Added new function silc_channel_payload_decrypt into the file
6456 lib/silccore/silcchannel.[ch].
6458 * Moved the channel message etc, check from silc_packet_decrypt
6459 to applications. The library calls now a generic
6460 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6461 when the packet is either normal or special. This was done to
6462 allow more wide range of checking that was not allowed when
6463 the code was in library. Now applications can do virtually any
6464 checks to the packet and return to the library the decision how
6465 the packet should be processed. Affected files are
6466 lib/silccore/silcpacket.[ch].
6468 Added silc_server_packet_decrypt_check to the server and
6469 silc_client_packet_decrypt_check to the client library.
6471 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6472 to send with specified source and destination information.
6474 * Channel message delivery between routers was broken after the
6475 channel key distribution was fixed earlier. The channel key
6476 was used be to distributed to other routers as well which is not
6477 allowed by the protocol. Now this is fixed and channel keys
6478 really are cell specific and the channel message delivery between
6479 routers comply with the protocol specification.
6481 * Fixed various commands in server to check also the global list
6482 for the channel entry and not just the local list. The affected
6483 file silcd/command.c.
6485 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Added assert()s to buffer formatting and unformatting routines
6488 to assert (if --enable-debug) when error occurs. Affected
6489 file: lib/silcutil/silcbuffmt.c.
6491 * Changed to auto-reconnect to check whether the remote host is
6492 router and register the re-connect timeout if it is. It used
6493 to check that whether we are normal server, but router must do
6494 auto-reconnect with another router as well. Affected file
6497 * Removed the [<key len>] option from CMODE command as the cipher
6498 name decides the key length, nowadays. See the defined ciphers
6499 from the protocol specification.
6501 * Added [<hmac>] option to the CMODE command to define the HMAC
6502 for the channel. Added SILC_CMODE_HMAC channel mode.
6504 * Added [<hmac>] option for the JOIN command so that user can
6505 select which HMAC is used to compute the MACs of the channel
6508 * Added Hmac field to the Channel Message Payload. The integrity
6509 of plaintext channel messages are now protected by computing
6510 MAC of the message and attaching the MAC to the payload. The
6511 MAC is encrypted. Now, it is clear that this causes some
6512 overhead to the size of the packet but rationale for this is that
6513 now the receiver can verify whether the channel message decrypted
6514 correctly and also when private keys are set for the channel the
6515 receiver can decrypt the packet with several keys and check from
6516 the MAC which key decrypted the message correctly.
6518 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6519 lib/silccrypt/silccipher.[ch].
6521 * Added silc_hash_len to return the digest length into the
6522 lib/silcrypt/silchash.[ch].
6524 * Rewrote parts of Silc Channel Payload interface in the
6525 lib/silccore/silcchannel.[ch]. The encode function now also
6526 encrypts the packet and parse function decrypts it.
6528 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Fixed a minor formatting bug in the SKE's key material processing.
6531 It actually might have processed the keys wrong way resulting
6534 * Redefined the mandatory HMAC algorithms and added new algorithms.
6535 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6536 and hmac-md5 truncated to 96 bits. The mandatory is now
6537 hmac-sha1-96. Rest are optional (including the one that used
6538 to be mandatory). Rationale for this is that the truncated HMAC
6539 length is sufficient from security point of view and can actually
6540 make the attack against the HMAC harder. Also, the truncated
6541 HMAC causes less overhead to the packets. See the RFC2104 for
6544 * Added new [hmac] configuration section. The SKE used to use
6545 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6546 is of course wrong. The official names that must be proposed in
6547 the SKE are the ones defined in the protocol specification
6548 (hmac-sha1-96 for example). The user can configure any hmac
6549 using any hash function configured in the [hash] section. At
6550 least, the mandatory must be configured.
6552 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6554 * Added HMAC list to the SKE proposal list. It has now both
6555 hash algorithm list and HMAC list. This makes the protocol
6556 incompatible with previous versions. The SKE now seems to work
6557 the way it is supposed to work, for the first time actually.
6559 * Defined plain Hash algorithms to the protocol specification.
6562 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Implemented support for key agreement packets into the server.
6565 Added functions silc_server_key_agreement and
6566 silc_server_send_key_agreement. Other than these functions,
6567 server has nothing to do with this packet.
6569 * Added support for private message key packets into the server.
6570 Added functions silc_server_private_message_key and
6571 silc_server_send_private_message_key.
6575 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6576 called in the protocol's final callback instead in the END
6577 protocol state. This makes a little more sense and in the same
6578 time in client we can use the same protocol routines for normal
6579 key exchange and to key agreement packet handling as well.
6581 * Added to both client's and server's KE protocol context the
6582 SilcSKEKeyMaterial pointer to save the key material. We will
6583 bring the key material to the protocol's final callback by doing
6584 this. The final callback must free the key material.
6586 * Added SKE's packet_send callback into client's KE protocol
6587 context so that the caller can choose what packet sending function
6588 is used. This way we can use different packet sending when
6589 doing normal SKE when doing key agreement packet handling (in
6590 the key agreement packet handling we do not want to encrypt
6593 * Implemented the responder side of the key agreement routines
6594 in the client. The client can now bind to specified port and
6595 accept incoming key negotiation. The key material is passed
6596 to the application after the protocol is over.
6598 * Implemented the processing of incoming Key Agreement packet
6599 in the client. Added function silc_client_key_agreement to
6602 * Implemented the intiator side of the key agreement routines
6603 in the client. The client can now initiate key agreement with
6604 another remote client. The key material is passed to the
6605 application after the protocol is over.
6607 * Created client_keyagr.c to include all the key agreement
6610 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6611 SILC_TASK_CALLBACK except that it is not static.
6613 * Created client_notify.c and moved the Notify packet handling
6614 from the client.[ch] into that file.
6616 * Created client_prvmsg.c and moved all private message and
6617 private message key routines from the client.[ch] into that file.
6619 * Create client_channel.c and moved all channel message and
6620 channel private key routines from the client.[ch] into that file.
6622 * Changed silc_client_get_client_by_id_resolve to resolve with
6623 WHOIS command instead of IDENTIFY command, in the file
6624 lib/silclient/idlist.c.
6626 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Implemented the SKE's responder side to the Client library.
6630 * When FAILURE is received to the protocol do not trust it
6631 blindly. Register a timeout to wait whether the remote closes
6632 the connection as it should do it, only after that process the
6633 actual failure. This was changed to both client and server.
6635 * Added client_internal.h to include some of the structures
6636 there instead of client.h in lib/silcclient/.
6638 * Added function silc_task_unregister_by_callback to unregister
6639 timeouts by the callback function.
6641 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * Some "Incomplete WHOIS info" errors has been appearing on the
6644 log files. Took away the entry->userinfo check from WHOIS
6645 reply sending. The entry->userinfo is now " " if client did not
6646 provide one. I thought this was fixed earlier but something
6647 is wrong still. Let's see if the error still appears.
6649 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Fixed a minor bug in the login when the channel key is
6652 re-generated in the server. It used to generate the key in
6653 wrong order and thus caused problems in the channel traffic.
6655 * Fixed a minor bug in channel key distsribution after
6656 KICK command. The key was not sent to the router even though
6659 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Added silc_ske_process_key_material_data as generic routine
6662 to process any key material as the SILC protocol dictates. The
6663 function is used by the actual SKE library but can be used by
6664 applications as well. This relates to the private message keys
6665 and the channel private keys since they must be processed the
6666 same way the normal SILC session keys. The protocol dictates
6667 this. Affected files: lib/silcske/silcske.[ch].
6669 Added also silc_ske_free_key_material to free the
6670 SilcSKEKeyMaterial structure.
6672 * Defined silc_cipher_set_key function to set the key for
6673 cipher without using the object's method function. The affected
6674 files: lib/silccrypt/silccipher.[ch].
6676 * Implemented silc silc_client_add_private_message_key,
6677 silc_client_add_private_message_key_ske,
6678 silc_client_del_private_message_key,
6679 silc_client_list_private_message_keys and
6680 silc_client_free_private_message_keys functions in the
6683 Added functions silc_client_send_private_message_key to send
6684 the Private Message Key payload and silc_client_private_message_key
6685 to handle incoming Private Message Key payload.
6687 * Added Cipher field to the Private Message Key payload to set
6688 the cipher to be used. If ignored, the default cipher defined
6689 in the SILC protocol (aes-256-cbc) is used.
6691 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6693 * Removed lib/silcclient/ops.h file.
6695 Redefined parts of the SILC Client Library API. Created new
6696 file silcapi.h that deprecates the ops.h file and defines the
6697 published Client Library API. Defined also private message key
6698 API and channel private key API into the file.
6700 This is the file that the application must include from the
6701 SILC Client Library. Other files need not be included by
6702 the application anymore.
6704 * Added new key_agreement client operation callback and also
6705 defined the Key Agreement library API for the application.
6707 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6710 is used by clients to request key negotiation between another
6711 client in the SILC network. If the negotiation is started it
6712 is performed using the SKE protocol. The result of the
6713 negotiation, the secret key material, can be used for example
6714 as private message key.
6716 Implemented the Key Agreement payload into the files
6717 lib/silccore/silauth.[ch].
6719 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Redefined ciphers for the SILC protocol. Added some new ciphers
6722 and defined the key lengths for the algorithms. Changed the
6723 code accordingly. The default key length is now 256 bits.
6725 * Fixed SKE key distribution function silc_ske_process_key_material
6726 when the key length is more than 128 bits. The default key
6727 length in SILC is now 256 bits.
6729 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6730 to indicate unsupported algorithm.
6732 * Renamed rijndael.c to aes.c and all functions as well.
6734 * Fixed a long standing channel key setting bug in client library.
6735 Weird that it has never surfaced before.
6737 * Fixed bug in channel deletion. If the entire channel is removed
6738 then it must also delete the references of the channel entry
6739 from the client's channel list as the client's channel entry and
6740 the channel's client entry share same memory.
6742 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Implemented CONNECT and SHUTDOWN commands in the client.
6746 * Implemented CLOSE command to the client.
6748 * Added the function silc_idlist_find_server_by_name into the
6749 files silcd/idlist.[ch].
6751 Added the function silc_idlist_find_server_by_conn into the
6752 files silcd/idlist.[ch].
6754 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * DIE command was renamed to SHUTDOWN. Updated the both code
6759 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6760 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6762 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6765 * Added function silc_server_create_connection function to create
6766 connection to remote router. My server implementation actually
6767 does not allow router to connect to normal server (it expects
6768 that normal server always initiates the connection to the router)
6769 so the CONNECT command is only good for connecting to another
6772 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6775 or some other client was kicked from the channel.
6777 Implemented the handling of the notify type to both client
6780 Implemented silc_server_send_notify_kicked to send the KICKED
6781 notify. It is used to send it to the server's primary router.
6783 * Implemented the KICK command into server and client.
6785 * Added `query' argument to the silc_idlist_get_client function
6786 to indicate whether to query the client from server or not if
6789 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6790 to indicate that the client is not channel founder.
6794 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Removed the rng context from SilcPacketContext structure and
6797 changed that the packet routine uses the Global RNG API.
6799 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Added support for quit message that client can "leave" on the
6802 channel when it quits the SILC. It is ditributed inside the
6803 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6805 Added silc_server_free_client_data that will take the
6806 signoff message as argument.
6808 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6810 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Updated parts of the protocol specification to keep it up
6815 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6818 payloads in one packet.
6820 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6821 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6822 use now the new List flag.
6824 * Also deprecated the following packet types: REPLACE_ID,
6825 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6827 * Added list support for Notify packet in server.
6829 * Added silc_server_send_notify_channel_change to send the
6830 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6831 the silc_server_send_replace_id.
6833 * Added silc_server_send_notify_nick_change to send the
6834 NICK_CHANGE notify type. Deprecates the function
6835 silc_server_send_replace_id.
6837 * Added silc_server_send_notify_join to send the JOIN notify type.
6838 Deprecates the function silc_server_send_new_channel_user.
6840 * Added silc_server_send_notify_leave to send LEAVE notify type.
6841 Deprecates the function silc_server_send_remove_channel_user.
6843 * Added silc_server_send_notify_cmode and
6844 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6845 types. Deprecates the silc_server_send_set_mode function.
6847 * Added SERVER_SIGNOFF notify type to indicate that server has
6848 quit. This means that all clients on the channel from that
6849 server will drop. This can be also used when netsplit happens.
6851 Deprecated REMOVE_ID packet type since it is not needed anymore
6854 Added silc_server_send_notify_server_signoff to send the
6855 SERVER_SIGNOFF notify type. Deprecates the function
6856 silc_server_send_remove_id.
6858 Added also silc_server_send_notify_signoff to send the
6859 SIGNOFF notify type.
6861 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6862 SILC protocol from this day on. Changed the protocol
6863 specification as well.
6865 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6866 notify type. It is used between routers to notify about
6867 topic changes on a channel.
6869 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6872 * Partly updated the protocol specification to comply with the
6873 changes now made. It is still though a bit outdated.
6875 * The JOIN notify type now takes one extra argument <Channel ID>.
6876 The packet used to be destined to the channel but now the
6877 JOIN type may be sent as list thus it is impossible to
6878 destine it to any specific channel. By adding this argument
6879 it is again possible.
6881 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Added CREDITS file. The CHANGES and CREDITS file will appear
6884 in the distribution as well.
6886 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6889 types in the server's silcd/packet_receive.c.
6891 * Implemented CMODE and CUMODE to work in router environment.
6893 * Fixed minor encoding and decoding buglet from the
6894 lib/silccore/silcmode.c.
6896 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6899 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6901 * Changed all SilcConfigServer* and silc_config_server* to
6902 SilcServerConfig* and silc_server_config*, respectively.
6905 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Associated the ID (client or server ID) to the Authentication
6908 Payload to avoid any possibility of forging. Updated the
6909 protocol specification and the code accordingly.
6911 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * The RSA key length is now save to the RsaKey context in the
6914 key generation process in lib/silccrypt/rsa.c. The key length
6915 is now used to figure out the maximum size of the block allowed
6916 to be encrypted/signed.
6918 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6919 is equivalent to the silc_mp_mp2bin but does not allocate any
6922 * Changed silc_mp_mp2bin API to take length argument. If it is
6923 non-zero then the buffer is allocated that large. If zero, then
6924 the size is approximated using silc_mp_sizeinbase, which however
6927 * Created Global RNG API which is global RNG that application can
6928 initialize. After initializing, any routine anywhere in the
6929 code (including library) can use RNG without allocating a new
6930 RNG object. This was done to allow this sort of use of the
6931 RNG in code that has no chance to allocate RNG object. All
6932 applications currently allocate this and many routines in the
6933 library use this. Affected file lib/silccrypt/silcrng.[ch].
6935 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6936 it to use the Global RNG API.
6938 * Defined Authentication Payload into protocol specification that
6939 is used during SILC session to authenticate entities. It is
6940 used for example by client to authenticate itself to the server
6941 to obtain server operator privileges.
6943 Implemented this payload into the lib/silccore/silcauth.[ch].
6944 Implemented also routines for public key based authentication
6945 as the new protocol specification dictates.
6947 Moved definitions of different authentication methods from
6948 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6950 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6951 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6952 silc_pkcs_verify_with_hash functions into the file
6953 lib/silccrypt/silcpkcs.[ch].
6955 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * The client entry's userinfo pointer must be always valid.
6958 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6959 will fail since it requires the userinfo. Now, the userinfo
6960 is allocated as "" if actual userinfo does not exist. Actually,
6961 it must exist and it is totally Ok to drop client connections
6962 that does not announce the userinfo. However, we will make
6963 this workaround for now.
6965 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6966 to return the remote port by socket.
6968 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6971 SILC_SERVER_PENDING_EXEC and added an new macro
6972 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6973 data or when error occurs while processing the pending command.
6975 Added new argument `destructor' into silc_server_command_pending
6976 and to the SilcServerCommandPending object. This destructor is
6977 now called after calling the pending callback or if error occurs
6978 immediately. If error occurs the actual pending callback won't
6979 be called at all - only the destructor. The destructor may be
6980 NULL if destructor is not needed.
6982 All this applies for client library code as well. Similar
6983 changes were made there as well for the pending commands.
6985 In the client, the application must now allocate the
6986 SilcClientCommandContext with the silc_client_command_alloc
6989 * Added reference counter to the SilcServerCommandContext. Added
6990 function silc_server_command_alloc and silc_server_command_dup
6993 Same type of functions added to the client library for the same
6996 * Removed the cmd_ident from IDListData away since it is now
6997 global for all connections. It is the command identifier used
6998 in command sending and with pending commands. The affected file
7001 * Added reference counter to the SilcSocketConnection objecet to
7002 indicate the usage count of the object. The object won't be
7003 freed untill the reference counter hits zero. Currently only
7004 server uses this, and client ignores it. The client must be
7005 set to use this too later. The affected files are
7006 lib/silccore/silcsockconn.[ch]. Added also the function
7007 silc_socket_dup to increase the reference counter.
7009 This was mainly added because it is possible that the socket
7010 is removed underneath of pending command or other async
7011 operation. Now it won't be free'd and proper DISCONNECTING
7012 flags, etc. can be set to avoid sending data to connection that
7013 is not valid anymore.
7015 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7016 the connection. After that it sets SILC_SET_DISCONNECTED.
7017 It is, however, possible that the socket data is not still freed.
7018 The silc_server_packet_process now checks that data is not
7019 read or written to connection that is DISCONNECTED. The socket
7020 get's freed when the reference counter hits zero.
7022 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Changed the client operation API: channel_message operation's
7025 `sender' is now the client entry of the sender, not the nickname
7026 and the `channel' is the channel entry, not the channel name.
7028 In the private_message operation the `sender' is now also the
7029 client entry of the sender not the nickname.
7031 Affected file is lib/silcclient/ops.h and all applications
7032 using the client operations.
7034 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Moved the calling of ops->connect() from connect_to_server_final
7037 into receive_new_id functin since that is the point when the
7038 client is actually allowed to send traffic to network. The
7039 affected file is lib/silcclient/client.c.
7041 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7043 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7044 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7045 (if needs broadcasting) instead of broadcasting the packets one
7046 by one which would make a burst in the network traffic.
7048 * Added `broadcast' argument to the functions in silcd/server.[ch]
7049 silc_server_create_new_channel[_with_id] to indicate whether
7050 to send New Channel packet to primary router.
7052 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Added new function into the silcd/server.[ch] files:
7055 silc_server_create_new_channel_with_id to create new channel with
7056 already existing Channel ID.
7058 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7059 lib/silccore/silcpacket.h. This packet is used t send list of
7060 Set Mode payloads inside one packet. Server uses this to set
7061 the modes for the channels and clients on those channels, that it
7062 announced to the router when it connected to it. The protocol
7063 specification has been updated accordingly.
7065 * The silc_server_new_channel did not handle the packet coming
7066 from normal server as it normally does not send that. However,
7067 when it announces its channels it does send it. Implemented
7068 the support for that.
7070 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7071 into the file lib/silccore/id.h.
7073 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Fixed memory leaks in the functions silc_idlist_del_client,
7076 silc_idlist_del_channel and silc_idlist_del_server in the file
7077 silcd/idlist.c. All of those leaked like a sieve.
7079 * Fixed some small memory leaks in the client's function
7080 silc_client_notify_by_server.
7082 * Added functions into silcd/server.c: silc_server_announce_clients,
7083 silc_server_announce_channels and silc_server_announce_server.
7084 These functions are used by normal and router server to announce
7085 to its primary router about clients, channels and servers (when
7086 router) that we own. This is done after we've connected to the
7089 These functions effectively implements the following packet types:
7090 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7091 and SILC_PACKET_NEW_ID_LIST.
7093 * Added new functions into the silcd/packet_receive.[ch]:
7094 silc_server_new_id_list, silc_server_new_channel_list and
7095 silc_server_new_channel_user_list to handle the incoming
7096 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7098 * Added support of changing Channel ID in the function
7099 silc_server_replace_id. If the server that announces a channel
7100 to the router already exists in the router (with same name but
7101 with different Channel ID), router is responsible to send
7102 Replace ID packet to the server and force the server to change
7103 the Channel ID to the one router has.
7105 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7106 client that the Channel ID has been changed by the router. The
7107 normal server sends this to the client. Client must start using
7108 the new Channel ID as the channel's ID.
7110 Implemented handling of this new type into lib/silcclient/client.c
7111 into the function silc_client_notify_by_server.
7113 * Added new function silc_idlist_replace_channel_id into the files
7114 silcd/idlist.[ch] to replace the Channel ID.
7116 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Call silc_server_command_identify_check always when processing
7119 the IDENTIFY command in silcd/command.c
7121 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7124 send keepalive packets. The packet can be sent by clients,
7125 servers and routers.
7127 Added function silc_socket_set_heartbeat into the file
7128 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7129 If not set, the heartbeat is not performed. The actual
7130 heartbeat is implemented in the low level socket connection
7131 library. However, application is responsible of actually
7134 Added silc_server_send_heartbeat to send the actual heartbeat
7135 packet into silcd/packet_send.[ch]. Server now performs
7136 keepalive with all connections.
7138 * Added silc_task_get_first function into lib/silcutil/silctask.c
7139 to return the timeout task with shortest timeout. There was a bug
7140 in task unregistration that caused problems. TODO has been
7141 updated to include that task system must be rewritten.
7143 * The client library will now resolve the client information when
7144 receiving JOIN notify from server for client that we know but
7145 have incomplete information.
7147 * Rewrote parts of silc_server_remove_from_channels and
7148 silc_server_remove_from_one_channel as they did not remove the
7149 channel in some circumstances even though they should've.
7151 * Encryption problem encountered in server:
7153 The LEAVE command used to send the Channel Key packet to the
7154 router immediately after generating it. However, the code
7155 had earlier sent Remove Channel user packet but not immediately,
7156 ie. it was put to queue. The order of packets in the router
7157 was that Channel Key packet was first and Remove Channel User
7158 packet was second, even though they were encrypted in the
7159 reverse order. For this reason, MAC check failed. Now, this
7160 is fixed by not sending the Channel Key packet immediately but
7161 putting it to queue. However, this is more fundamental problem:
7162 packets that are in queue should actually not be encrypted
7163 because packets that are sent immediately gets encrypted
7164 actually with wrong IV (and thus MAC check fails). So, packets
7165 that are in queue should be encrypted when they are sent to
7166 the wire and not when they put to the queue.
7168 However, the problem is that the current system has not been
7169 designed to work that way. Instead, the packet is encrypted
7170 as soon as possible and left to the queue. The queue is then
7171 just purged into wire. There won't be any fixes for this
7172 any time soon. So, the current semantic for packet sending
7175 o If you send packet to remote host and do not force the send
7176 (the packet will be in queue) then all subsequent packets to the
7177 same remote host must also be put to the queue. Only after the
7178 queue has been purged is it safe again to force the packet
7181 o If you send all packets immediately then it safe to send
7182 any of subsequent packets through the queue, however, after
7183 the first packet is put to queue then any subsequent packets
7184 must also be put to the queue.
7186 Follow these rules and everything works fine.
7188 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Added new function silc_server_remove_clients_by_server to
7191 remove all client entries from ID list when the server connection
7192 is lost. In this case it is also important to invalidate all
7193 client entires as they hold the invalid server entry. This
7194 fixes fatal bug when server has lost connection and will reconnect
7197 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Made some sanity checks to silc_server_daemonise like to check
7200 whether the requested user and group actually exists.
7202 * Added sanity check to SKE's silc_ske_responder_finish to check
7203 that the public and private key actually is valid.
7205 * Invalidate the client's nickname when receiving Replace ID
7206 packet and the Client ID is being replaced. This means that the
7207 server will query the nickname if someone needs it (client)
7210 * Sort the ID Cache in client library when the ID Cache data
7211 has changed (needs sorting).
7213 * Do not allow for SILC client to create several connections to
7214 several servers. The client does not support windows right now
7215 and generating multiple connections causes weird behaviour.
7217 Irssi-silc client does support windows and can handle several
7218 connections without problems, see: www.irssi.org and SILC plugin.
7220 * Fixed some places where client was added to the IDList. The
7221 rule of thumb is following (in order to get everything right):
7222 If the client is directly connected local client then the
7223 `connection' argument must be set and `router' argument must be
7224 NULL to silc_idlist_add_client function. If the client is not
7225 directly connected client then the `router' argument must
7226 bet set and the `connection' argument must be NULL to the
7227 silc_idlist_add_client function.
7229 * The funtion silc_server_packet_send_local_channel actually did
7230 not check whether the client was locally connected or not. It
7231 does that now. Fixed a bug related to LEAVE command.
7233 * Fixed Remove Channel User payload parsing bug in server's
7234 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7236 * The server's silc_server_save_channel_key now checks also the
7237 global ID list for the channel as it might not be in the local
7238 list. Fixed a bug related to LEAVE command.
7240 * Is this the end of the [<unknown>] buglet that has been lurking
7241 around for a long time? A little for loop fix in server's
7242 silc_server_command_whois_parse that is used by both IDENTIFY
7243 and WHOIS command. At least, this was a clear bug and a cause
7244 of one type of [<unknown>] buglet.
7246 * WHOIS and IDENTIFY commands call the function
7247 silc_server_command_[whois/identify]_check function even if
7248 we are not router server.
7250 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Added --with-gmp configuration option. If set the GMP
7253 is always compiled in the SILC source tree. If not set then
7254 it is checked whether the system has the GMP3 installed. If
7255 it has then the GMP won't be compiled (the system's headers
7256 and library is used), if it doesn't have it then the GMP is
7257 compiled in the SILC source tree.
7259 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Changed RSA private exponent generation to what PKCS #1
7262 suggests. We try to find the smallest possible d by doing
7263 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7264 not security fix but optimization.
7266 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added new config entry [Identity] to fork the server and run
7269 it as specific user and group. A patch from Bostik.
7271 * Imported Dotconf configuration library into lib/dotconf.
7272 This will be used to create the SILC configuration files later.
7273 It will appear in the distsribution after this commit.
7275 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * A big code auditing weekend happening. Auditing code for
7278 obvious mistakes, bugs and errors. Also, removing any code
7281 Removed files for being obsolete:
7283 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7284 inline in the file lib/silcutil/silcbuffer.h)
7286 o lib/silcutil/silcbufutil.c (the header has inline versions)
7288 Changed code to fix possible error conditions:
7290 o The buffer formatting routines now check that the destination
7291 buffer really has enough space to add the data. This applies for
7292 both buffer formatting and unformatting
7293 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7294 unformatting was changed to accomodate following rules:
7295 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7296 sent to the function while XXX_*STRING will not allocate or copy
7297 the data into the buffer. Instead it sets the pointer from the
7298 buffer into the pointer sent as argument (XXX_*STRING used to
7299 require that the pointer must be allocated already). This change
7300 makes this whole thing a bit more consistent and more optimized
7301 (note that the data returned in the unformatting with XXX_*STRING
7302 must not be freed now). The routines return now -1 on error.
7304 o Tried to find all code that use buffer_format and buffer_unformat
7305 and added return value checking to prevent formatting and
7306 especially unformatting errors and possible subsequent fatal
7309 o Changed ske->x and ske->KEY to mallocated pointers in
7310 lib/silcske/silcske.h. Fixed possible data and memory leak.
7312 o Added return value checking to all *_parse* functions. Fixed
7313 many memory leaks as well.
7315 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7316 so that buffer overflows would not happen. All code now also
7317 checks the return value as it can fail.
7319 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added reconnection support to server if the normal server looses
7322 its connection to the router (for example if router is rebooted).
7323 The server performs normal reconnection strategy implemented
7324 to the server. Affected file silcd/server.c.
7326 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added new packet type SILC_PACKET_SET_MODE that is used to
7329 distribute the information about changed modes (for clients,
7330 channels and clients channel modes) to all routers in the
7331 network. Updated the protocol specification accordingly.
7333 Added functions into silcd/packet_send.c and
7334 silcd/packet_receive.c: silc_server_send_set_mode,
7335 silc_server_set_mode.
7337 Added new files silcmode.[ch] into lib/silccore that implements
7338 the encoding and decoding of Set Mode Payload. Added new type
7339 SilcSetModePayload. Moved the definitions of different modes
7340 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7342 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * Oops, a little mistake in server's connection authentication
7345 protocol. The protocol is not ended with FAILURE but with
7346 SUCCESS if the authentication is Ok. :) Affected file is
7349 * Implemented NICK_CHANGE notify handling in server in the file
7350 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7351 the local clients on the channel. After the changing nickname
7352 in router environment snhould work and the [<unknown>] nickname
7353 should appear no more.
7355 The silc_server_replace_id function that receives the Replace ID
7356 payload now sends the NICK_CHANGE notify type also in the file
7357 silcd/packet_receive.c
7359 * Changed WHOIS and IDENTIFY command to support the maximum amount
7360 of arguments defined in protocol specs (3328 arguments). This
7361 fixed a bug that caused problems when there were more than three
7364 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Added extra parameter, command identifier, to the
7367 silc_client_send_command so that explicit command identifier
7370 Changed that ID list routines uses specific command identifier
7371 when sending WHOIS/IDENTIFY requests to the server so that they
7372 can be identified when the reply comes back.
7374 Affected files lib/silcclient/command.[ch],
7375 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7377 * Added `sender' argument to silc_server_packet_send_to_channel
7378 to indicaet the sender who originally sent the packet to us
7379 that we are now re-sending. Ignored if NULL. Affected file
7380 silcd/packet_send.[ch].
7382 * Added some server statistics support in silcd/server_internal.h
7383 SilcServerStatistics structure and around the server code. Also
7384 send some nice statistics information when client is connecting
7387 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Fixed channel ID decoding in server's JOIN command reply in
7390 silcd/command_reply.c
7392 * Fixed braodcasting of replace ID payload to not to send it if
7393 we are standalone server in silcd/packet_receive.c.
7395 * Fixed all channel message sending routines to not to send
7396 packets to clients that has router set, since they are routed
7397 separately in the same function earlier. Affects file
7398 silcd/packet_send.c and all channel packet sending functions.
7400 * In USERS reply, res_argv[i] are not allocated, the table
7401 is allocated. Thus changed that free the table, not its
7404 * In server's whois_check and identify_check if the client is
7405 locally connected do not send any WHOIS commands - they are not
7408 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * Fixed some minor bugs in client when sending WHOIS command. The
7411 arguments was in wrong order.
7413 * Removed statis function add_to_channel from server in
7414 silcd/command.c that was previously used with the joining but
7417 * Tested USERS command in router environment successfully with two
7418 routers, two servers and two clients.
7420 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Reorganized the USERS command and command reply in client library
7423 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7424 When the command is given by user we register a pending command
7425 callback that will reprocess the command after the reply has been
7426 received from the server. When reprocessing the packet we then
7427 display the information. Thus, the USERS information is displayed
7428 now in the command callback instead of in the command reply
7429 callback. The processing of the command is same as previously
7430 when server has sent the command reply in the JOINing process.
7432 * Added to USERS command in silcd/command_reply.c to join the client,
7433 we didn't use to know about, to the channel after we've created
7434 a client entry for it. Also, for clienet we did know already still
7435 check whether it is on the channel or not and add it if not.
7437 * Removed silc_server_command_join_notify as the function and its
7440 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7442 * Changed the client's pending command handling to the same as the
7443 server's pending command handling. It is also now possible to
7444 execute command reply functions from other command reply
7445 function as the function callbacks for commands and command
7446 replies are one and same. The pending commands are not static
7447 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7448 in client connection context. Thus, pending commands are server
7449 connection specific as it is convenient.
7451 Changed the function silc_client_command_pending and
7452 silc_client_command_pending_del and added new function
7453 silc_client_command_pending_check. Removed the
7454 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7457 * Added cmd_ident, current command identifier, to the client
7458 connection context in lib/silcclient/client.h to keep track on
7459 command identifiers used in command sending. Client's command reply
7460 function handling now supports the mandatory command identifiers.
7462 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7463 funtions in client to fully support pending command callbacks.
7465 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7466 as one of the arguments to the application in the command reply
7469 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7470 before first releasing SILC but came back. Now it is removed again
7471 and should come back nomore. The FORWARDED flag was used only
7472 by the JOINing procedure by forwarding the command packet to router.
7473 Now, the JOINing procedure has been changed to more generic (due
7474 to various router environment issues) and FORWARDED is not needed
7475 anymore for anything. The protocol specification is yet to be
7478 Now, removed silc_server_packet_forward from server and the flag
7479 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7481 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Renamed NAMES command to USERS command. The NAMES was named that
7484 due to historical reasons. Now it is renamed. Also, rewrote
7485 parts of the USERS command. The nickname list is not sent anymore
7486 by the server. Only Client ID and mode lists are sent in the USERS
7487 command. Changed this also to the protocol specification.
7489 The client now resolves the names and stuff after it receives
7490 the USERS list from the server when joining to the channel.
7492 * WHOIS and IDENTIFY commands has been changed to support multiple
7493 Client ID's per command. One can now search for multiple users
7494 in the network by sending only one WHOIS or IDENTIFY command.
7495 Changed the code and the protocol specifications.
7497 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7498 uses silc_server_command_whois_parse to parse the request. */
7500 * If normal server, do not parse the WHOIS and IDENTIFY requests
7501 before sending it to the router. Saves some time.
7503 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Fixed JOIN command on client library. Wrong number of arguments
7506 used to crash the client.
7508 * Added silc_server_channel_has_global function to check whether
7509 channel has global users or not.
7511 * Added silc_server_channel_has_local function to check whether channel
7512 has locally connected clients on the channel.
7514 * The silc_server_remove_from_one_channel now checks whether the
7515 channel has global users or not after given client was removed from
7516 the channel. It also checks whether the channel has local clients
7517 on the channel anymore. If it does not have then the channel entry
7518 is removed as it is not needed anymore.
7520 * The silc_server_notify now checks on JOIN notify whether the joining
7521 client is one of locally connected or global. If it is global then
7522 the channel has now global users on the channel and that is marked
7523 to the channel entry. Also, it now saves the global client to
7524 global list who is joining and JOINs it to the channel. This is
7525 for normal server, that is.
7527 Changed silc_server_send_notify_on_channel,
7528 silc_server_packet_relay_to_channel and
7529 silc_server_packet_send_to_channel check if we are normal server
7530 and client has router set (ie. global client) do not send the
7531 message to that client, as it is already routed to our router.
7533 * Implemented LEAVE notify type handling in silc_server_notify
7536 * Tested LEAVE command in router environment successfully. Tested
7537 with two routers, two servers and two clients.
7541 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7543 * Implemented SIGNOFF notify type handling in silc_server_notify
7546 * silc_server_remove_id now removes the client entry from all channels
7547 it has joined and thusly sends SIGNOFF notify type.
7549 * Rewrote the NAMES list generation in server by removing two excess
7550 loops. The lists are created now inside one loop.
7552 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * silc_server_remove_channel_user checks now also global list
7555 for channel and client.
7557 * silc_server_new_channel_user checks now both local and global
7558 list for channel and client. Fixed a bug in client id decoding.
7559 Used to decode wrong buffer.
7561 * silc_server_channel_message checks now both local and global
7562 list for channel entry.
7564 * Tested channel joining (hence JOIN) in router environment
7565 successfully. Tested with two routers, two servers and two
7568 * Tested channel message sending in router environment successfully.
7570 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Added silc_server_save_channel_key into server.[ch] to save the
7573 received channel key in Channel Key payload processing. It is
7574 also used in JOIN command reply handling.
7576 Equivalent function silc_client_save_channel_key added into
7577 client.[ch] into client library.
7579 * Changed JOIN command reply to send information whether the channel
7580 was created or not (is existing already) and the channel key
7581 payload. Changed protocol specs accordingly.
7583 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7584 the request was sent by ID and not by nickname. Crashed on
7587 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7589 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7590 now correctly save the received data.
7592 * silc_server_free_sock_user_data now notifies routers in the
7593 network about entities leaving the network.
7595 At the same time implemented functions silc_server_remove_id
7596 and silc_server_send_remove_id to receive and send REMOVE_ID
7597 packets. The packet is used to notify routers in the network
7598 about leaving entities. The ID removed will become invalid in
7601 * Added function silc_idlist_del_server into server. Removes and
7602 free's server entry from ID list.
7604 * silc_server_private_message function now checks, if we are router,
7605 that the destination ID really is valid ID, naturally.
7607 * In router when NEW_ID packet is received (for new client) the
7608 hash of the Client ID is saved in the ID Cache but the
7609 client->nickname is set to NULL, instead of putting the hash
7612 IDENTIFY command now also checks that client->nickname must be
7613 valid. If it is not if will request the data from the server who
7614 owns the client. Added new function
7615 silc_server_command_identify_check.
7617 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7618 to set the command to already allocated Command Payload.
7620 * Tested private message sending in router environment with two
7621 routers, two servers and two clients. Fixed minor bugs and now
7624 * Fixed segfault from client's NAMES command. Used to crash if
7627 * Forwarded packets must not be routed even if it is not destined
7628 to the receiver. Changed server code comply with this.
7630 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Added `require_reverse_mapping' boolean value to ServerParams
7633 structure. If TRUE (not default) the server will require that
7634 the connecting host has fully qualified domain name.
7636 If the reverse mapping is not required and hostname could not be
7637 found the IP address is used as hostname.
7639 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Implemented version string checking to both client and server.
7642 The check is incomplete currently due to the abnormal version
7643 strings used in development version of SILC.
7645 * Changed all command functions in server to use the new
7648 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Changed char *data to unsigned char *data in ID Cache system to
7651 support binary data as ID Cache data. Changed code to support
7652 binary data in lib/silccore/idcache.c.
7654 * Renamed silc_server_packet_relay_command_reply to
7655 silc_server_command_reply as it is normal packet receiving
7656 function. Rewrote the function to accept command replys for
7657 servers and not only for clients.
7659 * Mark remote router always as registered server if we are connecting
7660 to it. Otherwise, commands sent by the router to us are ignored.
7662 * All ID List find routines now returns the ID Cache Entry pointer
7663 as well if requested.
7665 * WHOIS command works now in router environment, tested with two
7666 routers, two servers and two clients.
7668 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7669 in router environment (as it is almost equivalent to WHOIS) but
7670 hasn't been tested thoroughly. Added new functions:
7672 silc_server_command_identify_parse
7673 silc_server_command_identify_send_reply
7674 silc_server_command_identify_from_client
7675 silc_server_command_identify_from_server
7677 * Disabled route cache adding because adding two different ID's with
7678 same IP replaces the old cache entry thus giving wrong route.
7679 The entry->router->connection is always the fastest route anyway
7680 so route cache may not be needed. Of course, new routes maybe
7681 established after receiving the ID when the entry->router->connection
7682 might not be anymore the most optimal.
7684 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Add route cache for received ID for fast routing.
7688 * Added silc_server_packet_route to route received packet on router
7689 that is not destined to us.
7691 * Renamed silc_server_get_route to silc_server_route_get.
7693 * Added id_string and id_string_len fields into SilcServer to
7694 include encoded ServerID for fast comparing without excess
7695 encoding of the ID's.
7697 * Cleaned up WHOIS command on server side. Added following static
7700 silc_server_command_whois_parse
7701 silc_server_command_whois_check
7702 silc_server_command_whois_send_reply
7703 silc_server_command_whois_from_client
7704 silc_server_command_whois_from_server
7706 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7707 arguments in command replies. All command functions should be
7708 updated to use this macro.
7710 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7712 * Minor typo fixes on command reply handling on server.
7714 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Added silc_server_command_add_to_channel internal routine to add
7717 the client to the channel after router has created the channel and
7718 sent command reply to the server.
7720 * Added generic silc_server_send_command to send any command from
7723 * Use static buffer with ID rendering instead of duplicating data.
7725 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7727 * Fixed a channel user mode bug when joining to a channel server gave
7728 everybody channel founder rights, oops.
7730 * We mark ourselves as the router of the incoming server connection
7731 if we are router ourselves. This way we can check in some packet
7732 sending functions whether it is locally connected server. For
7733 incoming router connections we put NULL.
7735 * For router sending packets locally means now always sending the
7736 packet cell wide; to local clients and local servers. For normal
7737 server sending packet locally means sending it to only local
7740 * Fixed the JOIN command to really work in router environment. If the
7741 channel is created it is always created by the router. Router is
7742 also responsible of making the initial joining to the channel,
7743 sending JOIN notify to the sending server and distributing
7744 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7745 does not exist server doesn't do anything else but forward the
7746 command to the router which performs everything.
7748 * Added silc_server_send_channel_key function to send the Channel Key
7751 * Added silc_server_create_channel_key to create new channel key. The
7752 channel key is now re-generated everytime someone joins or leaves
7753 a channel, as protocol dictates. Note: channel->key_len is the
7756 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7759 packet_receive.[ch] to separate packet sending and receiving
7760 routines. The server.[ch] now includes everything else including
7761 actual packet processing (writing and reading data) and other
7764 Renamed silc_server_private_message_send_internal to
7765 silc_server_send_private_message. The routine is still though
7766 used only to relay private messages as server does not send
7767 private messages itself.
7769 Renamed silc_server_new_channel to silc_server_create_new_channel
7770 and added new function sicl_server_new_channel that handles the
7771 incoming New Channel packet. Added also new sending function
7772 silc_server_send_new_channel to send New Channel Payload.
7774 * Added new function silc_server_notify to process incoming notify
7775 packet to the server/router. Server may then relay the notify
7776 to clients if needed.
7778 * Added new function silc_server_new_channel_user to process incoming
7779 New Channel User packet. Router will redistribute the packet and
7780 send JOIN notify to its local clients and locally connected servers
7781 if needed. Normal server will send JOIN notify to its local client
7782 on same channel when received this packet. Added also corresponding
7783 sending function silc_server_send_new_channel_user to sent the
7786 * Added boolean route argument to send_notif_to_channel and
7787 packet_send_to_channel functions to attempt to route the packet
7788 if it is TRUE and send only locally if it is FALSE.
7790 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * silc_server_replace_id now broadcasts the received replace ID
7793 packet if it is not broadcast packet already. The router must
7794 broadcast to inform other routers about changed ID.
7796 * Added backpointer to server's router into SilcServer context in
7797 silcd/server_internal.h.
7799 * Fixed silc_server_packet_broadcast to send correct broadcast
7802 * The channel key is now distributed to the local client as soon
7803 as it is received from the router (in router environment) so that
7804 no other packet may be sent for the channel until client has
7807 * silc_server_remove_channel_user now broadcasts the received
7808 Remove Channel User packet if it is not broadcast packet already.
7809 The router must broadcast to inform other routers about removed
7812 * Added users field into SilcPacketContext that is a reference count
7813 of the context. One can increase the reference count by calling
7814 silc_packet_context_dup which is now changed to just increase the
7815 reference count instead of duplicating the data. The reference
7816 count is decresed by calling silc_packet_context_free that will
7817 free the data after the reference count hits zero.
7819 For now on the packet context and everything allocated into it
7820 (including the raw packet from network) must be freed by calling
7821 the new silc_packet_context_free function. Added also new function
7822 silc_packet_context_alloc that must be used now to allocate the
7823 context. This also means that if a routine is asynchronous from
7824 silc_[client/server]_packet_parse_type the packet context must
7825 be duplicated by calling silc_packet_context_dup. Otherwise it
7826 gets free'd after silc_[client/server]_packet_parse_type returns.
7827 Also, one must remember that if packet is duplicated then its
7828 reference count must be decresed by calling the free function as
7829 many times as it was duplicated.
7831 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7832 from both client and server.
7834 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Made joining to a channel working in router environment.
7838 * Cleaned up JOIN command on server side and create function
7839 silc_server_command_join_channel internal routine to make the
7842 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7844 * Changed silc_command_pending list to SilcDList. Also, added
7845 `ident' field to SilcServerCommandPending structure to identify
7846 the reply and to call correct callback.
7848 Added silc_server_command_pending_check function to replace the
7849 corresnponding macro. The silc_command_pending list is not
7852 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7853 to set identifier to previously allocated Command Payload. It
7854 is used to set identifier for command when resending Command
7857 * Added silc_command_payload_encode_payload to encode Command
7858 Payload buffer from SilcCommandPayload structure.
7860 * Added silc_argument_payload_encode_payload to encode Argument
7861 payload buffer from SilcArgumentPayload structure.
7863 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * Changed WHOIS command to support router connection on server side.
7866 The whois request is always sent to router unless the server is
7867 standalone server. After server has received the reply from the
7868 router will it send the reply to the client.
7870 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7871 broadcast received broadcast packet. The function is used only
7872 by router. The broadcast packet is always sent to the router's
7875 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7876 render given ID to printable string, for log files for example.
7878 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Made basic router to router connections working. At least they
7881 can now connect to each other but nothing really works the way
7882 they are supposed - yet.
7884 * Added new initiator token to RouterConnection configuration
7885 file in silcd/serverconfig.[ch]. It is used to tell whether we
7886 are the initiator to the remote router or whether we'll expect
7887 the other end to connect.
7889 * Moved registering of listener task to silc_server_init, hence
7890 the server starts listenning as soon as it is run, even if it
7891 does not have connections to other routers. Let's see how well
7894 * Changed default connection retry timeouts for more suitable in
7897 * Removed cipher and such arguments from silc_idlist_add_client
7898 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7899 Added new function silc_idlist_add_data to add the keys and stuff
7902 * Added SilcIDListData structure and added it to SilcClientEntry
7903 and SilcServerEntry as their first field in the structure. This
7904 way we can explicitly cast the ID entries to the SilcIDListData
7905 structure and get common data for the entries. In past, we had
7906 to first check what type of connection it is and then cast it to
7907 correct ID entry type. Now, we can directly cast the opaque
7908 pointer to the SilcIDListData (no matter what ID entry it actually
7909 is) and get the data needed.
7911 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7914 in some circumstances even if threre were timeout tasks, though not
7915 IO tasks, but tasks anyway. Now fixed.
7917 * Defined SilcServerConnection structure to hold connection specific
7918 stuff about directly connected servers and routers. The definition
7919 is currently in silcd/server_internal.h. I thought about having
7920 a bit more important role fro this struct but for now it is used
7921 only when connecting to other server (or router actually).
7923 * Added connecting retry support in server when connecting to
7924 router(s). The retry feature implement exponential backoff
7925 algorithm. Also, added SilcServerParams structure to hold default
7926 parameters for server. For now, it include these retry settings
7927 and are hard coded. After server is moded to be as Silc Server
7928 Library this structure will be more important.
7930 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Changed client librarys channel->clients table to SilcList and
7933 changed code accordingly.
7935 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Changed client's channel table to SilcList and changed code
7938 accordingly. Also changed SilcChannelClientEntry to include back-
7939 pointer to the channel so that client entry can use that structure
7940 as list as well and we have fast cross-reference to the channel.
7941 This change dramatically decreased the complexity of channel
7942 handling with client entry and vice versa (removed one extra
7943 loop when searching for channel entry from many functions).
7945 * Changed server->sim from table to SilcDList and changed code
7948 * NAMES command can now be used from user interface. It will show
7949 the user list on the channel, neatly.
7951 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7952 Code now saves realname of the user if it becomes available.
7954 * Renamed configure.in to configure.in.pre and made ./prepare
7955 script to automatically add correct version string to
7956 configure.in which it creates from configure.in.pre.
7958 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * NAMES command reply now shows users mode with the nickname when
7963 * Moved silc_client_ch[u]mode[_char] functions from
7964 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7965 place sucks, they are utility functions and should be in some
7968 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7970 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7973 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Added TRQ (efficient deque and list library) into lib/trq. This is
7978 a very good list library that is currently used in the SILC. Defined
7979 SilcList API over the library because I didn't like the API very
7980 much. See lib/trq/silclist.h for the API and examples of how to
7981 use the API. Fixed various places in the code to use the new
7982 SilcList API. The SilcList is meant for lists that has a structure
7983 already defined as a list. It is not suitable to add just some
7984 context to the list (in TRQ, the context is the list actually).
7986 So, I defined SilcDList that can be used for the purpose where
7987 predefined list structure does not exit. This can be used as
7988 such list. Now some context just can be added to the SilcDList.
7989 Currently this list is not used in the SILC just yet, though there
7990 are a lot places where this can replace dynamically allocated
7991 tables and I will fix these places, later, to use SilcDList.
7992 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7993 and use TRQ internally).
7995 Also fixed some annoying warning messages that the original TRQ
7996 code generated. Also minor changes to TRQ's Makefile.in.
7998 * Added support for querying by Client ID to both WHOIS and
7999 IDENTIFY commands into server, as required by the protocol.
8001 * Removed method function pointers from SilcBuffer structure. They
8002 weren't used to anything and just increased the context size for
8003 no good reason. This change also made silc_buffer_alloc and
8004 silc_buffer_free functions inline functions.
8006 * Disabled command flooding detection support until it's fixed so
8007 that it accepts commands in but does not execute them more than once
8010 * Added silc_net_localhost(), to return local hostname, into
8011 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8012 that must be initialized before calling silc_client_init.
8014 * Added new function: silc_server_send_notify_on_channels to send
8015 notify messages to all channels client has joined. It is assured
8016 that the message is sent only once per client.
8018 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8019 lib/silcutil/silcutil.[ch] as silc_format function. The new
8020 function is generic and is used by server as well, not only by
8021 the logging routines.
8023 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8024 the provided version string was not acceptable. Added new function:
8025 silc_ske_check_version into lib/silcske/silcske.h. The function
8026 must be implemented by the application (client or server) and it
8027 does not reside in the SKE library. The function checks the version
8028 string remote end sent.
8030 * Added back pointers (to opaque context and to SilcSocketConnection)
8031 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8033 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8034 duplicate packet context structure.
8036 * Changed `notify' client operation to send same arguments as client
8037 receives from server except for ID's. ID's are mapped to correct
8038 ID entry and that is returned. Also, if channel entry is not sent
8039 by server but the notify is for channel the channel entry is sent
8040 to application (otherwise application doesn't know that it is for
8041 channel (library gets it from packet's Destination ID)).
8043 * Added silc_client_remove_from_channels into client library to
8044 remove a client from all channels it has joined to. Used when
8045 received SIGNOFF notify from server. Added also new function
8046 silc_client_replace_from_channels to replace old ID entry with
8047 new ID entry on all channels. Used when received NICK_CHANGE
8050 * Fixed ID Cache list handling in silc_idlist_get_client in
8051 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8052 to get (or query) client by ID.
8054 * Updated TODO list.
8056 * Added connection authentication status message defined by the
8057 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8058 support for these into the code in client and server side.
8060 * Added generic function silc_client_send_command to send any command
8061 with variable argument list. Application should use this function
8062 to send commands if the command functions provided by the library
8063 does not suite for the application's user interface needs.
8065 * Added new `failure' client operation. Application is notified about
8066 received failure packet if client is executing a protocol. In this
8067 case the protocol's execution has failed.
8069 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8070 is required by the protocol.
8072 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8073 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8076 * Added status flag to SilcSKE object to indicate realtime status
8077 of the SKE protocol.
8079 * Application receives now exactly same command reply arguments as
8080 the library receives from server. However, if ID is received the
8081 corresponding ID entry is returned to the application (eg. Client
8082 ID is mapped to correct SilcClientEntry entry and that is returned).
8083 Changed command_reply client operation due to this change.
8085 * Changed all ID's in commands and in command replys as ID Payloads.
8086 Change affected both client and server side codes.
8088 All ID's sent in SILC network (with execption of ID's in SILC
8089 Packet header) are sent in ID Payload to support variable length
8092 * Server now notifies nick changes and notifies all clients on
8093 the channels about the new nickname (about the new Client ID,
8096 * Implemented CMODE command to change channel modes. Supports all
8097 channel modes defined by the protocol specs except ban and invite
8098 lists. (Also, private channel key mode is supported but support for
8099 setting private channel key in client is missing, thus, this mode
8100 has no effect on client side (except that server requires that the
8101 client uses private channel key and normal channel traffic does not
8104 Also, invite mode works per se, but INVITE command does not work
8105 yet correctly, so you can set channel as invite only channel but
8106 inviting clients to the channel does not work (it is yet to be
8107 thought what's the best way to do it).
8109 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8110 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8111 Implemented CUMODE command to change user's mode on the channel.
8112 Supports all modes defined by the protocol specs.
8114 * Added NAMES command reply to return users modes on the channel.
8116 * Removed unnecessary and slow ciphers from lib/silccrypt.
8118 * Set SO_KEEPALIVE option to connection sockets by default.
8120 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8122 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8123 redefined the Notify Payload into protocol specs.
8125 * Added silc_id_payload_parse_id to get ID directly from raw
8128 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8130 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8131 accept searching by Client ID as well.
8133 * Added support for LEAVE and SIGNOFF notify types in client library.
8135 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8136 to parse ID Payload from raw data.
8138 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Added flags parameter into silc_ske_assemble_security_properties
8141 function in lib/silcske/silcske.[ch].
8143 * Changed notify client operation to fit better for notify messages
8144 sent by server. The notify payload received from server is now
8145 passed to the application (after parsing it to SilcNotifyPayload).
8146 It is application's responsibility to retrieve the arguments
8147 from the payload and show the message the way it wants. The message
8148 sent by server is implementation specific.
8150 * Changed public keys to comply with the protocol specification.
8151 Old public keys are not supported anymore and are not compatible.
8153 * Removed nickname from Channel Payload as the latest draft removed
8154 it. The client must resolve the nickname from the NAMES command
8155 reply received when it joined the channel.
8157 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8159 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8161 * Fixed some errors in protocol specification drafts.
8163 * Created lib/silccore/silcnotify.c to implement Notify Payload
8164 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8165 generic payloads described by protocol specifications. The file
8166 includes implementations for ID Payload and Argument Payload.
8168 * Changed Command Payload implementation to use the new Argument
8169 Payload. Changed command_xxxx_payload to command_payload_xxxx
8170 to comply with SILC coding conventions.
8172 * Added suppport for Argument Payload handling in Notify Payload
8173 implementation as protocol requires it. Added the new support
8174 into server and client lib as well.
8176 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8178 * Added support for multiple nicknames on same channel. [n] is
8179 added locally to the nickname if there are more than one same
8180 nicknames on the channel.
8182 * Server now sends all nicknames that matched WHOIS request.
8183 Client also shows the list received from server.
8185 * Added TOPIC command to client side. User can now set and show
8186 current topic on channel.
8188 * Added MOTD command to client and server. Also, server sends the
8189 motd when client connects to the server.
8191 * Changed version strings to comply ISO 8601.
8193 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8195 * Fixed protocol error handling in client library. It should now
8196 cope even if the SKE fails for some reason.
8198 * Made new protocol specification drafts for submitting to IETF.
8200 * Implemented TOPIC command to server in silcd/command.c.
8202 * Added two new notify types into lib/silccore/silcnotify.h:
8203 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8204 notify nickname change and topic setting/change on a channel.
8206 * API change of command_reply operation in client library. The
8207 application gets now the status type received from server as well.
8209 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8211 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8213 * Cras fixed and optimized the packet handling even further and
8214 it should work now. Minor change to the prototype of function
8215 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8217 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8219 * Added new function into lib/silcutil/silcschedule.[ch]:
8220 silc_schedule_with_fd to select() a specified fd. The function
8221 returns after timeout expires or data arrives or goes. The
8222 function is used by packet routines to wait that all data is
8223 received from network.
8225 * Fixed data reading from network in lib/silccore/silcpacket.c.
8226 The code now assures that all data is read from the fd and then
8227 continues packet processing. This was a bug fix since the code
8228 used to drop some data in some circumstances.
8230 * Added new function into lib/silcclient/client.[ch]:
8231 silc_client_start_key_exchange to start key exchange after
8232 connection has been established to server. The code internally
8233 now uses this funtion but its main purpose was to provide it
8234 for applications that perform their own connecting. After
8235 application has created a connection it merely calls this
8236 function to start the key exchange between client and server.
8237 The library takes care of everything else after that.
8239 Updated also lib/silcclient/README to explain the usage of
8242 * Do not send to application information that connection has
8243 been established. Application gets notified it by connect
8246 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Applied cras's patch to add silc_schedule_one function. The
8249 function runs scheduler once and returns.
8251 * Fixed the scheduler after cras messed it up. The timeout
8252 handling works now as it's supposed to work.
8254 * Added into lib/silccore/ silcnotify.h to include notify
8255 message types support. Changed silc_server_send_notify*
8256 functions, in server.[ch], to support those new notify types.
8257 Added the support for the notify types into client library,
8258 as well. Added new notify client operation into ops.h in
8261 * Changed silc_server_packet_send_to_channel to send normal
8262 packets instead of just channel message packets. The function
8263 is now used to send the notify packets to channels. It is not
8264 used to send channel message packets anymore, as server never
8267 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8268 va_arg()s as it seems to require it nowadays. I guess, if SILC
8269 is compiled with older va_arg() the new code should work anyway.
8271 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Splitted core library. Core library (lib/silccore) includes
8274 now only SILC protocol specific core (and common) components.
8275 Created new utility library (lib/silcutil) that includes more
8276 generic purpose stuff. The stuff for util library was taken
8277 from the old core library. This was minor and easy split.
8279 * Created SILC Client Library (lib/silcclient) that includes
8280 implementation of the SILC client without user interface. This
8281 was major move from silc/ directory. The code has been changed
8282 so that it is transparent towards the user interface. The
8283 silc/ directory includes now the same user interface as before
8284 and it uses the new client library. Read lib/silcclient/README.
8285 Basicly, the client library performs everything else related
8286 to SILC except user interface handling. Also, configuration
8287 files are considered to be part of user interface and library
8288 does not handle them.
8290 This change also changed a lot of structures, function naming etc.
8291 Most important change was that SilcClientWindow object was
8292 renamed to SilcClientConnection in the client library. Created
8293 also new file lib/silcclient/ops.h. Also added new files
8294 silc/local_command.[ch] and silc/client_ops.[ch].
8296 All these changes were made to make it easier for user interface
8297 designers to create what ever user interface for the SILC client
8300 It is also expected that the server will be moved to lib
8301 directory as well and SILC Server Library will be created;
8302 sometimes in the future.
8304 * Removed Local commands from lib/silccore/silccommand.h as
8305 they are application specific and new client library does not
8306 handle any of those anymore.
8308 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8309 old client implementation in silc/.
8311 * Added support for callback functions in SILC_LOG_* macros.
8312 Application can now set its own callbacks that will be called
8313 instead of using the default functions that will always print
8314 the debug messages to stderr (or stdout). Also, debugging can
8315 now be disabled by setting silc_debug to FALSE and re-enabled by
8316 setting it to TRUE. Note, that logging will still work even
8317 if debugging is disabled.
8319 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8320 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8321 silc_log_reset_debug_callbacks.
8323 * To enable debugging in silc client one must give now -d
8324 option on command line.
8326 * Changed silc_schedule_init to automatically allocate task queues
8327 if they are not allocated before calling it.
8329 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8331 * Added GMP 3.1 into math library.
8333 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8335 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8336 a channel in SILC network. The packet is used by servers and
8337 routers to notify other routers that user has left a channel.
8338 This little feature was missing until now. Added the feature
8339 to protocol specification as well.
8341 Added functions: silc_server_send_remove_channel_user and
8342 silc_server_remove_channel_user into server.[ch].
8344 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8345 lib/silccore/silcpacket.h. However, they are not implemented
8348 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8350 * Fixed joining to a channel and sending channel messages
8351 between server and router. The channel message sending should
8352 now work inside a cell.
8354 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8356 * Fixed the private message sending between server and router.
8357 The private message sending should now work inside a cell.
8359 * Added silc_server_replace_id into server.[ch] to replace
8360 existing ID in the SILC network.
8362 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8363 and silc_idlist_replace_server_id into idlist.[ch] in server.
8365 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8367 * Fixed the server to server connections. Server can again now
8368 connect to router. Router to router connections probably does
8371 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8373 * Added dynamic protocol registering support. Now protocols can
8374 registered and unregistered on the fly. Patch by cras.
8376 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Added lib/contrib directory to hold routines that some platforms
8379 don't have but are needed by SILC.
8381 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8382 into lin/contrib to provide getopt() and getopt_long() for
8383 those who don't have it.
8385 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8387 * Added AWAY command to client. When away message is set and
8388 client receives a private message packet the client automatically
8389 replies to the sender with the away message.
8391 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8392 bug seemed to be the cause of recent problems when compiling
8395 * Added version detection support to SKE protocol specification
8396 and added the new changes to the SKE implementation as well.
8397 There were other minor changes in the SKE protocol as well.
8399 Many changes in lib/silcske/silcske.[ch] and in
8400 lib/silcske/payload.[ch].
8402 * Added ^U functionality, clear input line. Patch from cras.
8404 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * Mainly small bugfixes on core library. Fixed some debugging
8407 logging and buffer overflow in silclog.c.
8409 * Updated config.sub and config.guess on the distribution tree.
8411 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8413 * Added command lagging support in server. Client may execute
8414 commands now only once in two seconds.
8416 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8418 * Optimized packet reception. MAC computation and checking is now
8419 also more optimized. A lot previously duplicated code is now
8420 used as generic by both client and server.
8422 * Fixed key pair generation in clientutil.c
8424 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Added into lib/silccore/silcbufutil.[ch] new function;
8427 silc_buffer_realloc.
8429 * Moved generic packet sending/encryption functions to
8430 lib/silccore/silcpacket.[ch] from client and server. Some
8431 rewriting of the functions.
8433 * Moved all generic packet reception/decryption functions to
8434 lib/silccore/silcpacket.[ch] from client and server. The
8435 packet processing is now much cleaner in both client and server.
8436 These were major changes in both client and server.
8438 * Created many common functions in server to do packet sending.
8439 Previously code were duplicated a lot, this has been removed
8442 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * Rewrote major parts of the ID cache system. Don't know
8445 whether it is better now or not but at least the API is more
8448 * Major rewrite on ID cache stuff on client because of the ID
8449 cache API changes. Added idlist.c to client.
8451 * Also major rewrite on ID cache stuff on server as well.
8452 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8453 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8454 in hand, instead they are all put into the ID cache system now.
8455 All server_idlist_* routines uses ID cache now instead of
8456 traversing its own lists (those lists does not exist anymore).
8457 SilcIDList though still exists. Also, SilcXXXEntry's are
8460 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8462 * Finally made the SKE implementation compliant to the protocol
8463 specification. All mp integers are now binary encoded as
8464 opposed being HEX encoded.
8466 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8469 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8470 functions: silc_[encode/decode]_pem. Also added function
8471 silc_encode_pem_file to PEM encode with newlines ('\n') for
8474 * SILC public keys are now encoded either PEM or binary. Same
8475 option is for private keys as well. By default private keys
8476 are binary encoded and public keys PEM encoded. Silly HEX
8477 encoding were removed.
8479 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8480 function to create fingerprints.
8482 * Fixed a bug in SHA1; does not change the original data anymore.
8484 * Partly implemented INFO command on client and server side.
8485 Fixed CLEAR command. Changes to SERVER command; show current
8486 server(s) when giving command without arguments. Added
8487 VERSION command to client.
8489 * Added check to server that unregistered connections cannot
8490 execute commands (unless it is specificly allowed).
8492 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8494 * Fixed screen refresh.
8496 * Fixed channel joining bug from client. On some circumstances
8497 client tried to join to a channel it had already joined.
8499 * Added public key verification process into client's protocol.c.
8500 The client now verifies the public key from user and saves
8501 it into ~./silc/serverkeys/ directory.
8503 Added into: clientutil.[ch]: silc_client_verify_server_key.
8505 * Changed SKE protocol's silc_ske_initiator_finish function
8506 to accept callback function that verifies the received public
8507 key. Removed old silc_ske_verify_public_key function.
8509 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8511 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8512 silc_pkcs_private_key[_data]_set.
8514 * Made the password and public authentication more cleaner in
8515 server's protocol.c.
8517 * Removed historic and obsolete protocol `channel_auth' from
8518 both client and server.
8520 * Removed wrong way of sending command status messages from
8521 server to client in server's command.c. The old way violated
8522 protocol specification.
8524 Changes to silccore/silccommand.[ch]: removed
8525 silc_command_encode_status_payload -> not needed anymore,
8526 changed silc_command_encode_payload_va to accept extra
8527 argument on variable argument list. The argument type must
8528 now be provided to the function. Also, added new function:
8529 silc_command_encode_reply_payload_va which is same as
8530 normal command_encode_payload_va except command status type
8531 is provided as extra argument.
8533 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8535 * Added ~./silc directory handling. The directory includes the
8536 public and private keys for the client.
8538 Added silc_client_check_silc_dir, silc_client_create_identifier
8539 and silc_client_load_keys.
8541 * Implemented SILC protocol compliant public key. Added public
8542 and private key saving to and loading from files.
8544 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8545 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8546 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8547 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8548 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8550 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8551 silc_pkcs_load_[public/private]_key.
8553 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8555 * Added silc_server_get_route (route.[ch]) to get connection
8556 data for the fastest route for given ID.
8558 * Implemented INVITE command on client and server. The command
8559 were re-defined in the SILC Protocol Specification and the
8560 implementation now complies with the specification.
8562 * Implemented PING command on client and server.
8564 * Implemented NAMES command on client and server. The server side
8565 supports currently only normal server not router server yet.
8566 Some changes to NAMES definition in SILC protocol specification.
8568 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8570 * Implemented LEAVE command on client and server.
8572 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8573 again. This change was made to the protocol as well. Server
8574 should not violate the protocol specification anymore.
8576 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8578 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8579 was tested. SOCKS4 was not but should work anyway.
