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

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

640 silcd/packet_receive.c, packet_send.[ch],
641 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
642 The killer's client entry is now returned to application in
643 the `notify' client operation.
645 * Fixed the Max Argument fields that had too large value set
646 in the protocol specs. Protocol TODO #14.
648 * Added the LEAVE command reply to return the ID of parted
649 channel. Updated protocol specs and implemented it to the
650 client and server. Protocol TODO #15. Affected files are
651 silcd/command.c, lib/silcclient/command_reply.c. The channel
652 entry is now returned to application in the `command_reply'
655 * Rewrote the version SKE version checking in client libary
656 and in server to use the silc_parse_version_string. Affected
657 files are lib/silcclient/protocol.c, silcd/protocol.c.
659 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
660 commands that was missing it, and updated protocol specs and
661 the server implementation. Protocol TODO #10. The affected
662 file is silcd/command.c.
664 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
665 generic reply to a generic request (REQUEST flag), and
666 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
667 way. A draft-riikonen-silc-flags-payloads-00.txt is written
668 to define the payload for DATA flag. Added the flags to
669 the implementation. Protocol TODO #9. Affected file is
670 lib/silccore/silcchannel.h.
672 Changed the client library to return the message length
673 to application as well in the channel_message and private_message
674 client operations. Affected files are
675 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
676 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
677 and lib/silcclient/client_ops_example.c.
679 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
680 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
681 the channel. Updated protocol specs and impelemented this
682 to client and server. Protocol TODO #6. Affected files are
683 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
684 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
686 Added new options m and M to CMODE command in Irssi SILC
687 client to set these modes.
689 * Deprecated all administrative commands from SILC protocol
690 since they are highly implementation specific commands.
691 Updated protocol specs. Moved the old commands in
692 implementations to private range of command types. Affected
693 files are silcd/command.c, lib/silcclient/command.c and
694 lib/silcclient/command_reply.c. Protocol TODO #8.
696 * Fixed a bug in server where sending unknown command crashes
697 the server. Affected file silcd/command.c.
699 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Added SILC_PROTOCOLVERSION macro to check protocol version
702 of a socket connection. The affected file is
703 lib/silcutil/silcsockconn.h.
705 * Added better error logging in rekey protocol. Affected file
708 * Do not check public key types in SKE during rekey. Affected
709 file lib/silcske/payload.c.
711 * Fixed the rekey protocol with PFS, which was totally broken.
712 Affected file silcd/protocol.c.
714 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
716 * Some client implementations quit network by doing first LEAVE
717 and then immediately SIGNOFF (like Bombyx). We now do check
718 after a short time after LEAVE notify and check whether the
719 client is still valid after LEAVE, and if not we remove it from
720 cache. Affected file is lib/silcclient/client_notify.c.
722 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
724 * Merged version 1.1.4 of zlib. Even if it not currently in use,
725 it's good not to have security holes here.
727 * Fixed a negative refcount situtuation for the config context.
728 Affected file is silcd/serverconfig.c.
730 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
732 * ROBOdoc documented lib/silcutil/silcutil.h.
734 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
736 * Optimized even more the SilcPacketContext structure. Now
737 totally saved 16 bytes of memory per context after optimization.
738 Affected files are lib/silccore/silcpacket.[ch].
740 * Made strict checks for valid SILC IDs. Affected file is
741 lib/silccore/silcid.c.
743 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Changed the object argument for silc_cipher_register,
746 silc_hash_register, silc_hmac_register and silc_pkcs_register
747 to const. Affected files are lib/silccrypt/silccipher.[ch],
748 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
750 * Changed the silc_get_username and silc_get_real_name to
751 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
753 * Fixed the Irssi SILC Client to use the silc_get_username and
754 silc_get_real_name insted of glib routines since the glib
755 routines only corrupt stack. Fixes the Irssi SILC to work in
756 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
758 * Fixed the Irssi to not use g_get_home_dir since it crashes
759 or returns garbage on cygwin and corrupts stack. Added function
760 get_home_dir to Irssi routines. Affected files are
761 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
763 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
765 * Made some structure optimizations. SFTP memory FS MemFSEntry
766 entry structure. Optimized SilcTask structure. Optimized
767 SilcPacketContext structure.
769 Affected files lib/silcsftp/sftp_fs_memory.c,
770 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
772 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * And yet again reverted back the config thing since Johnny
775 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
778 * Fixed memory leaks from config object. Affected files are
779 silcd/serverconfig.[ch].
781 * Added support for adding new connections to the server in rehash.
782 After rehash they take effect.
784 Added support for changing the maximum allowed connections in
785 rehash. The number can grow but going smaller is not supported.
787 Added function silc_server_num_sockets_by_remote to the
788 silcd/server_util.[ch].
790 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
792 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
794 * Added preliminary checking during config parsing for a valid
795 public/private key and removed further checks in the code.
796 Affected files are silcd/serverconfig.[ch], server.c.
798 * Moved functions silc_server_drop() and silc_server_daemonise()
799 from server.c to silcd.c since they are stricly related to
800 the application activity.
802 * Reverted a small part of the automatic ref/unref since
803 it caused a double unref in some situations. Affected
804 files are silcd/silcd.[ch], server.c, serverconfig.c.
806 * Added some .cvsignore files in the lib directory.
808 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Fixed silc_net_gethostbyaddr to correctly resolve by
811 address. Affected file lib/silcutil/silcnet.c.
813 * Fixed the notify relaying to client. The HMAC to be used
814 with relayed packets ws wrong and caused decryption failure
815 at the client end. Affected file is silcd/packet_receive.c.
817 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
819 * Created new branch silc_protocol_1_0_branch.
821 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
823 * Changed the silc_server_config_* routines to be SilcServer
824 independent. They are now officially application specific code
825 and not part of generic server implementation. Affected files
826 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
828 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Added automatic referencing of config context in the
831 silc_server_config_alloc, and automatic unreferencing in the
832 silc_server_config_destroy. Affected files are
833 silcd/serverconfig.[ch], silcd/silcd.c.
835 * Fixed the silc_log_quick handling in the logging routines.
836 It didn't log quickly when it was TRUE. Affected file is
837 lib/silcutil/silclog.c. Also the flush delay was set even
838 if it was 0 in config file. Affected file is
839 silcd/serverconfig.c.
841 * Added support for changing key pair of the server in rehash.
842 Affected file silcd/server.c.
844 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
846 * Fixed the TOPIC_SET notify to not cras. It changed the topic
847 too early, before getting the channel entry. Affected file
848 is silcd/packet_receive.c.
850 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
852 * Added functions silc_server_config_[ref/unref], these are used
853 to prevent that the config object is destroyed.
855 No longer directly affect global variables silc_log_quick and
856 silc_log_delay, they are first cached inside the config object
857 and then applied with silc_server_config_setlogfiles().
859 silc_server_config_set_defaults() is now internal to
860 serverconfig.c, there are no reasons to show this internal stuff
863 Affected files are silcd/serverconfig.[ch].
865 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
866 fprintf's to stderr, since some code may be executed again after
867 the server went into the background. Affected files are
870 * Added rehash support. Added function silc_server_rehash() that
871 will perform all the basic tasks of the rehashing procedure.
873 * Added command line option `-x, --hexdump'. This will enable the
874 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
875 The option `--hexdump' implies `--debug'.
877 * Fixed a bad bug in the logging APIs (silcutil library) where
878 the application would crash after calling silc_log_reset_all().
880 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
882 * Fixed the KICKED notify handling in client library to
883 correctly remove the channel and all entries from the
884 channel when I was kicked. This bug crashed the client.
886 Fixed yet another but in KICKED notify handling to remove
887 the kicked client correctly from the channel.
889 Affected file is lib/silcclient/client_notify.c.
891 * Fixed a minor bug in looking up correct client entry
892 in KICKED notify in server. Affected file is
893 silcd/packet_receive.c.
895 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
896 sources correctly to distribution. Fixes --with-gmp option.
898 * Removed the manual rehashing from ID Cache, and changed it
899 to use the SILC Hash Table's auto rehash feature. Affected
900 file is lib/silccore/silcidcache.c.
902 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
904 * Fixed a bug in the silc_client_nickname_format function that
905 handles the multiple same nickname formatting. Two clients
906 with same nickname caused problems after the first one left
907 and rejoined. It didn't format the nickname correctly.
908 Affected file is lib/silcclient/idlist.c.
910 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
912 * Don't change the topic if olod topic is same as new one.
913 Affected file is silcd/packet_receive.c.
915 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
917 * Added cross-reference support to the SILC Documentation
918 generator. All types across all HTML files are now cross-
919 referenced. Affected files util/robodoc/generator.c and
920 scripts/silcdoc/silcdoc.
922 * Added file lib/silcutil/silctypes.h to include all the
923 arithmetic type definitions and some macros. Removed
924 includes/bitmove.h and moved macros to silctypes.h.
926 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
928 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

932 * Added `type' argument to silc_id_payload_parse_id function which
933 now returns the type of the ID to the sent pointer. Affected
934 file is lib/silccore/silcid.[ch].
936 * Added check for CMODE_CHANGE notify type that mode change is
937 allowed by the sender. Affected file silcd/packet_receive.c.
939 * Added check for CUMODE_CHANGE notify type that mode change is
940 allowed by the sender. Affected file silcd/packet_receive.c.
941 Added the ID type as CUMODE_CHANGE notify type as argument
942 to the `notify' client operation. Affected files are
943 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
945 * Added function silc_client_add_server to the client library.
946 Added support for resolving also channel and server info when
947 received unknown entity in notify packet. Affected files are
948 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
950 * Added function silc_command_get_status to return the command
951 status from the command reply's argument payload. Affected files
952 are lib/silccore/silccommand.[ch].
954 * Added check for KICKED notify type that the kicking is
955 allowed by the client. Affected file silcd/packet_receive.c.
957 * Created function silc_get_input which can be used to get input
958 (echo on or off) from user on command line. Affected files are
959 lib/silcutil/silcutil.[ch].
961 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
963 * Optimized silc_server_packet_relay_to_channel function.
964 Added new function silc_channel_message_payload_encrypt which
965 can be called directly if channel message payload needs to
966 be encrypted and is already encoded (no need to call _encode
967 function). Packet relaying is now done by router without any
968 extra memory allocations. Affected files are
969 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
972 * Fixed the INVITE notify handling. It took wrong arguments
973 as invite list and invite delete. Affected file is
974 silcd/packet_receive.c.
976 * Added check for TOPIC_SET notify type that the topic change is
977 allowed by the client. Affected file silcd/packet_receive.c.

985 Affected files are silcd/server_util.[ch], silcd/command.c.
987 * Added function silc_server_check_umode_rights to check whether
988 changing client's user mode is allowed. Added check for
989 UMODE_CHANGE notify type that the umode change is allowed
990 by the client. Affected files are silcd/server_util.[ch],
991 silcd/packet_receive.c and silcd/command.c.
993 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
996 ID length. It ignored that ID can be IPv6 based as well.
997 Affected file lib/silccore/silcpacket.h.
999 * Fixed the silc_id_id2str and silc_id_str2id to take the
1000 IPv6 address offset's into consideration. Affecte file is
1001 lib/silccore/silcid.c.
1003 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed the internal Unix scheduler functions to check for
1006 NULL context they may receive. The affected file is
1007 lib/silcutil/unix/silcunixschedule.c.
1009 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1011 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1012 can specify different directory with --home command line
1013 parameter. Affected files irssi/src/silc/core/client_ops.c,
1016 * SILC-specific commands aren't now executed if the active server
1017 isn't of SILC-type, so there won't be problems with having
1018 IRC and SILC protocol support in same client. Affected files
1019 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1022 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1024 * Improved the signal support in SILC Schedule. Added new
1025 function silc_schedule_signal_call which is used by application
1026 to mark a signal to be called. It is now safe to perform
1027 any kind of tasks in signal callbacks since it is guaranteed
1028 that the application specified signal callback is called
1029 after the signal is over. Affected files are
1030 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1032 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1034 * Added `name' field to SilcChannelPrivateKey to represent
1035 application given name for the key. Moved also the context from
1036 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1037 Added the `name' argument also to the function
1038 silc_client_add_channel_private_key.
1040 Added function silc_client_current_channel_private_key to set the
1041 current channel private key in use.
1043 Added "change" command to KEY command which can be used to change
1044 the current channel private key. Bound the command also to
1045 alt+K (Alt+Shift+k).
1047 Also affected files lib/silcclient/client_channel.c,
1048 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1050 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1052 * Added silc_rng_get_byte_fast function in to the
1053 lib/silccrypt/silcrng.[ch].
1055 * Changed the interface of silc_packet_assemble and the
1056 silc_packet_send_prepare. If silc_packet_assmble is now
1057 called the application does not call silc_packet_send_prepare
1058 because the library will call it automatically. These
1059 interfaces now also return a reference to the outgoing buffer
1060 which includes the assembled packet, which the application can
1061 use to encrypt the packet.
1063 Affected files are lib/silccore/silcpacket.[ch],
1064 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1065 silcd/packet_send.c, server_backup.c and packet_receive.c.
1067 * Fixed a packet sending bug on very high load, where outgoing
1068 packet queue wasn't handled correctly and packets got corrupted.
1069 Affected files are lib/silcutil/*/silc*sockconn.c,
1070 lib/silcclient/client.c and silcd/server.c.
1072 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1074 * Added macro SILC_PACKET_DATALEN which can be used during
1075 packet assembling to check whether the data to be added to
1076 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1077 len is truncated until it fits it.
1079 Added checks for maximum length of channel message payload and
1080 private message payload also.
1082 Added checks for maximum packet length in server and in
1085 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1086 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1087 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1088 lib/silcclient/client_prvmsg.c.
1090 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1092 * Added silc_server_packet_queue_purge call to the
1093 silc_server_disconnect_remote to assure that all data in the
1094 queue before disconnecting is sent to the network. Affected
1095 file silcd/server.c.
1097 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1099 * Added the deleting of server's own ID cache entry to the
1100 silc_server_free function. Free also everything else that
1101 has been allocated in silc_server_init. The affected file
1104 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1106 * Added functions silc_parse_version_string, silc_version_to_num,
1107 and silc_ske_parse_version to parse SILC protocol style version
1108 strings. Affected files lib/silcutil/silcutil.[ch] and
1109 lib/silcske/silcske.[ch].
1111 * Added new configuration params: version_protocol, version_software
1112 and version_software_vendor to specify what version the remote
1113 host must at least be to be able to connect to server. The vendor
1114 string can be regex matched too. Added new function
1115 silc_server_connection_allowed to check maximum number of allowed
1116 connections, and allowed versions for incoming connections.
1117 Affected files are silcd/server.c, server_util.[ch] and
1120 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Added preliminary support for signals in scheduler. The
1123 signals we care about are now blocked always when the scheduler
1124 is locked. This way we can synchronise the use of signal with
1125 scheduler. It is guaranteed that when signal occurs the scheduler
1126 is not locked, and thus new tasks can be safely added to the
1129 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1130 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1131 Added new platform specific routines
1132 silc_schedule_internal_signals_[un]block and
1133 silc_schedule_internal_signal_[un]register.
1135 Added new functions to SILC Schedule API:
1136 silc_schedule_signal_[un]register. Each signal that application
1137 is going to use should be registered to the scheduler.
1139 Affected files are lib/silcutil/silcschedule.[ch],
1140 lib/silcutil/*/silc*schedule.c.
1142 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Check for unauthenticated client and server in the
1145 silc_server_new_client and silc_server_new_server functions.
1146 Affected file silcd/packet_receive.c.
1148 * Added function silc_string_is_ascii to check whether given
1149 string is 7-bit ASCII string. Affected files are
1150 lib/silcutil/silcutil.[ch].
1152 * Added function silc_id_is_valid_server_id into the
1153 silcd/serverid.c and added checking for valid Server ID's in
1154 silc_server_new_server. The Server ID must always be based
1155 on the server's public IP address.
1157 * Added logging of DISCONNECT packet message in the server.
1158 Affected file silcd/server.c.
1160 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Changed all library interfaces that use Global RNG to also
1163 accept SilcRng as argument. Affected files are
1164 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1165 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1166 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1167 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1168 lib/silccrypt/rsa.c.
1170 * Added function silc_pkcs_generate_key to the
1171 lib/silccrypt/silcpkcs.[ch] for applications so that they
1172 don't need to do pkcs->pkcs->init calls anymore.
1174 * Remove SilcSocketConnection from the SFTP API since it really
1175 wasn't needed there. The application has the information
1176 saved in its contexts anyway and the SFTP layer doesn't need
1177 know about it. Affected files lib/silcsft/silcsftp.h and
1178 lib/silcsftp/sftp_[server/client].c.
1180 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1181 The SilcSimContext is not SilcSim.
1183 * Fixed possible buffer overflows in silc_id_render in the
1184 lib/silcutil/silcutil.c.
1186 * On EPOC the global crypto module lists are not used at all
1187 in the crypto library. Added support for using the constant
1188 algorithm list on EPOC. Affected files are
1189 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1192 * Fixed the handling of third parameter of KICKED notify, since
1193 it was mistakenly updated to SILC Protocol 1.0 even though it
1194 is to be included in 1.1. Since it is not in 1.0 it is not
1195 mandatory, and this fix now handles it only if it is provided,
1196 and it is not error if it is not provided. Affected file
1197 lib/silcclient/client_notify.c.
1199 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1202 client. Affected file irssi/src/silc/core/client_ops.c.
1204 * Merged with Irssi 0.8.4 from irssi.org CVS.
1206 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Check for valid socket connection in client entries before
1209 sending any messages. Fixes a crash, but doesn't fix some
1210 other underlaying bug that is lurking there. Affected
1211 file silcd/packet_send.c.
1213 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1215 * $usermode, $cumode and $cumode_space expandos shouldn't do
1216 anything with non-SILC server records. Affected file
1217 irssi/src/silc/core/silc-expandos.c
1219 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1221 * Fixed the silc_net_check_[host/local]_by_sock to support
1222 IPv6 bound sockets as well. Now they can return IPv6 addresses
1223 as well. Affected file lib/silcutil/silcnet.c.
1225 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1226 Affected lib/silcutil/unix/silcunixnet.c.
1228 * Fixed ID rendering (at least on some platforms, not NetBSD)
1229 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1231 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1233 * Added silc_hash_public_key and silc_hash_public_key_compare
1234 functions to be used with SilcHashTable. They can be used to
1235 hash public keys and compare public keys in hash table. Affected
1236 file lib/silcutil/silcutil.[ch].
1238 * Added support for specifying multiple public keys for Client
1239 connection section in server configuration file. This makes it
1240 possible to accept multiple public keys from same host, or to
1241 make a section that accepts any incoming host, and have the
1242 accepted public keys listed in the section.
1244 Added functions silc_sever_[find/get]_public_key, added the
1245 support for this actually to all connection sections but only
1246 the Client section is currently allowed to specify multiple
1249 Affected files are silcd/server.c, server_internal.h,
1250 command.c, protocol.c, server_util.[ch], packet_receive.c.
1252 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Merged Irssi 0.8.2 from irssi.org CVS.
1256 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1258 * If silc_debug is TRUE, also output standard logging messages
1259 to stderr with the debug output.
1261 Made silc_log_reset_all() flushing all channels before returning.
1262 Also fixed some documentation typos.
1264 Affected files are lib/silcutil/silclog.[ch].
1266 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1268 * Fixed the server to check correctly the amount of connections
1269 from single host, by checking also the type of the connection.
1270 Fixed also the comparison of number of connections and number
1271 of allowed connections. Affected files are silcd/server.c,
1274 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1276 * Fixed the USERS command reply to save the user's mode on the
1277 channel as well. Fixed JOIN command reply to check whether a
1278 client is on channel already and not join it twice. Affected
1279 file lib/silcclient/command_reply.c.
1281 * Added new file silc-expandos.c into irssi/silc/core/ to return
1282 various stuff for various signal for the statusbar etc. updating.
1283 Now Irssi SILC client prints channel user modes etc. on the
1286 * The user mode (like server/router operator changes) is now shown
1287 on the Irssi SILC client's statusbar. The affected files are
1288 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1290 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1292 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1293 to SILC_SCHEDULE_[UN]LOCK macros.
1295 * Added more error printing to logs in server code. Affected
1296 files silcd/server.c and silcd/protocol.c.
1298 * Fixed -S option parsing in Irssi SILC Client. Affected file
1299 irssi/src/silc/core/silc-core.c.
1301 * Added silc_buffer_alloc_size function. Affected file is
1302 lib/silcutil/silcbuffer.h.
1304 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1307 constants. Affected files in
1308 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1311 * Changed the internal SFTP Memory FS table to const. Affected
1312 file lib/silcsftp/sftp_fs_memory.c.
1314 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1316 * Fixed the buffer formatting and unformatting routines to
1317 check the size of 64 bits types with sizeof(). Affected
1318 file is lib/silcutil/silcbuffmt.c.
1320 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * Removed 0.6.x backwards support.
1324 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1326 * Changed all integer type names:
1327 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1328 to avoid collisions with other libraries using same type names
1331 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1333 * Added `prefer_ipv6' argument to the functions
1334 silc_net_gethostbyname[_async]. If it is TRUE it will return
1335 IPv6 address over IPv4. If FALSE IPv4 address is returned
1336 even if IPv6 address was found. Affected files
1337 lib/silcutil/silcnet.[ch].
1339 * Added support silc_net_create_connection[_async] to fallback
1340 to IPv4 address if IPv6 address could not be used (like if
1341 it doesn't work on a specific system). Affected file in
1342 lib/silcutil/unix/silcunixnet.c.
1344 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Added silc_schedule_reinit function to do the enlarging
1347 of the max tasks handling capabilities of the scheduler.
1348 Affected files lib/silcutil/silcschedule.[ch].
1350 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1352 * Added automatic extern "C" { ... } for C++ compilers so the
1353 application does not need to define them. Affected file
1354 includes/silcincludes.h.
1356 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1357 old name went against naming convention. Applications now
1358 include "silcclient.h" instead of "clientlibincludes.h".
1359 Removed includes/clientlibincludes.h, it is redundant now.
1361 * Renamed includes/version.h to silcversion.h.
1363 * Added really preliminary support for OS/2 into the util
1364 library. Only thread & mutex API is implemented, others
1365 are still to be implemented. Created the lib/silcutil/os2/
1366 directory. Created also file includes/silcos2.h.
1368 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1370 * Added preliminary BeOS support into the util library.
1371 Created lib/silcutil/beos/, and implemented all the needed
1372 functions to support SILC on BeOS. Created also file
1373 includes/silcbeos.h.
1375 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1377 * Added proper initializations to silc's irssi code, so it's
1378 now possible to load it as module. Affected files
1379 irssi/src/silc/core/silc-core.c,
1380 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1382 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1387 * Fixed the silcdoc document generator to correct generate
1388 docs from all kinds of filenames. Affected files are
1389 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1391 * ROBOdoc documented lib/silcutil/silcmemory.h.
1392 Added also new function silc_memdup.
1394 * Removed lib/silcutil/silcbufutil.h and moved those routines
1395 to the lib/silcutil/silcbuffer.h.
1397 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1399 * Added `user_count' to the SilcChannelEntry which now tells the
1400 number of users on the channel. The user count is now saved
1401 in normal server of global channels as well. Affected files
1402 silcd/server.c, idlist.h, packet_receive.c and command.c.
1404 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1405 include file utility functions.
1407 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1408 instead of calling directly OS routines.
1410 * Fixed NICK change printing in Irssi SILC Client. Fixed
1411 KICKED notify printing in Irssi SILC Client. Affected file
1412 irssi/src/silc/core/client_ops.c.
1414 * Fixed a NICK change bug in client library, to not recreate the
1415 client_entry->channels hash table everytime nick is changed.
1416 Affected file lib/silcclient/client.c.
1418 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1420 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1421 the SKE interface a bit.
1423 * Fixed padding problem in PKCS#1. The padding was not actually
1424 random since the random number generator was used incorrectly.
1425 This security bug affects only when encrypting with PKCS#1, and
1426 it is not currently used at all in SILC. SILC only use signing
1427 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1429 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1431 * Rewrote the notify handling in Irssi SILC client to not call
1432 the events as signals. Fixes problems with Perl support.
1433 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1435 * Send the auto-nicking NICK command in client library with
1436 little timeout after connecting. The affected file is
1437 lib/silcclient/client.c.
1439 * Added following new config file settings:
1440 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1441 key_exchange_timeout, conn_auth_timeout, connections_max,
1444 Implemented all the new config settings handling in the server.
1446 Optimized the use of SKE Mutual flag usage. Use it only
1447 if connection authentication protocol is not based in public
1450 Renamed all SilcServerConfigSection* to SilcServerConfig*
1451 to have a bit shorter names.
1453 Affected files silcd/serverconfig.[ch], server.[ch], and
1456 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1458 * Cleaned up the listening sockets code, preparing for the rehash
1459 support. Affected file is silcd/server.c.
1461 * Fixed some output messages. Affected files are silcd/silcd.c,
1464 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1466 * Create lib/doc/silcrng_intro.html document as introduction
1467 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1469 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1471 * Fixes to the silcd config template. Affected file is
1472 doc/example_silcd.conf.in.
1474 * Removed type casts from silc_calloc(), conforming to the
1475 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1477 * Removed param_name member from client, server, and router
1478 section structs, now identifying the param directly.
1480 Added CONFIG_FREE_AUTH macro in config file parsing.
1482 Affected files are silcd/serverconfig.[ch].
1484 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1486 * Fixed command line parameter handling. All SILC initialization
1487 is now done in silc_core_init() which also fixes autoconnecting
1490 Affected files irssi/src/silc/core/silc-core.c,
1491 irssi/src/fe-text/silc.c.
1493 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Added new configuration options and blocks:
1496 keepalive_secs, reconnect_count, reconnect_interval,
1497 reconnect_interval_max, reconnect_keep_trying and
1498 require_reverser_lookup. Added ConnectionParam block, and
1499 implemented the connection parameters when connecting as
1500 initiator and when accepting connections as responder.
1502 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1503 whether given configuration value has been given already.
1505 Affected files silcd/serverconfig.[c], server.[c].
1507 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1508 algorithm parts and created new file silcalgs.conf, that
1509 is now included from the example_silcd.conf.in.
1511 * Optimized the silc_server_connect_to_router_second to take
1512 the connection configuration object from the SilcServerConnection
1513 object instead of finding it during the connecting phase.
1514 Added the configuration object to SilcServerConnection struct.
1515 Affected files silcd/server_internal.h, server.c.
1517 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1519 * Add the client on channel after it was resolved at the
1520 channel message receiving, and it was not already on the
1521 channel. Affected file lib/silcclient/client_channel.c.
1523 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Fixed the public key authentication to allocate always the
1526 destination signature buffer instead of using static buffer.
1527 Affected file silcd/protocol.c.
1529 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Unified the serverconfig.[ch]'s helper function interface.
1532 Affected file silcd/serverconfig.[ch].
1534 * Removed doc/example_silc.conf.in since it is redundant.
1535 The make install will now install irssi/silc.conf file.
1537 * Added new Passphrase and Publickey authentication methods to
1538 config file, allowing both public key and passphrase based
1539 authentication to be set at the same time.
1541 Added `prefer_passphrase_auth' setting in config file which
1542 can be used to set to prefer passwd auth if both passwd and
1543 public key is set. If not set, public key is preferred.
1544 This has effect only when being initiator (responder will try
1547 Added support for authentication with passphrase and public key
1548 at the same time. The passphrase is tried first always since
1549 it is faster to check.
1551 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1553 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1555 * Merged the new SILC Config library, with the server parsing
1556 support. Read the header file silcconfig.h or the toolkit
1557 documentation for the news. Affected files are
1558 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
1559 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
1560 silcd/protocol.c silcd/server.c silcd/server_backup.c
1561 silcd/serverconfig.[ch] silcd/silcd.c.
1563 * Fixed some silclog documentation. Affected file is
1564 lib/silcutil/silclog.h.
1566 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1568 * The silc_cipher_register, silc_hash_register and
1569 silc_hmac_register now checks if the object to be registered
1570 is registered already. Affected files are
1571 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1573 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1575 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

1579 * Allow zero length channel messages inside the Channel Message
1580 Payload. Affected file lib/silccore/silcchannel.c.
1582 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1583 as header filenames.
1585 * Removed lib/silcclient/README and created HTML file
1586 lib/silcclient/silcclient_using.html, which is now included
1587 as part of Toolkit documentation.
1589 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1591 * Fixed CUMODE_CHANGE notify handling to change the mode of
1592 correct client. Affected file lib/silcclient/client_notify.c.
1594 * Make silc_rng_alloc fail if it cannot allocate the sha1
1595 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1597 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1599 * Fixed the file transfer's key agreement payload to include
1600 zero port also if the hostname is NULL because it could not
1603 Call file transfer monitor callback now also if error occurs
1604 during key agreement protocol.
1606 Changed the silc_client_file_send interface to return the
1607 SilcClientFileError instead of session id. The session ID
1608 is returned into pointer provided as argument.
1610 Check that the file exists locally before sending the
1611 file transfer request at all.
1613 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1615 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1616 error than can occur while key agreement protocol. Affected
1617 file lib/silcclient/silcapi.h.
1619 * Fixed the event_mode CMODE handler to not crash when mode
1620 is changed and +k mode is set in the channel. Affected file
1621 irssi/src/silc/core/silc-channels.c.
1623 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1624 SILC_LOG_WARNING to give out Warning and not Error. Affected
1625 file lib/silcutil/silclog.c.
1627 * Fixed the channel message payload decryption in the function
1628 silc_channel_message_payload_decrypt to not modify the original
1629 buffer before it is verified that the message decrypted
1630 correctly. Otherwise, next time it is called with correct
1631 channel key it won't encrypt since the payload is corrupted.
1632 Affected file lib/silccore/silcchannel.c.
1634 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Do not constantly resize the window. A fix patch by cras.
1637 Affected file irssi/src/fe-text/screen.c.
1639 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1641 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1642 Affected file lib/silcutil/silcnet.c.
1644 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1646 * Fixed a bug in hash table internal routine for traversing
1647 the table with foreach callback. The current entry may
1648 become invalid in the callback but it was referenced after
1649 the callback returned.
1651 Do not allow auto rehashing of hash table during the
1652 silc_hash_table_foreach operation, for same reasons as it is
1653 not allowed for SilcHashTableList. Affected files are
1654 lib/silcutil/silchashtable.[ch].
1656 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1659 Win32 DLL. extern's in header files are now declared with
1662 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Fixed private message handling. It used some old code that
1665 caused the client to crash. Affecte file is
1666 lib/silcclient/client_prvmsg.c.
1668 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Added function silc_client_add_channel,
1671 silc_client_replace_channel_id, and removed functions
1672 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1673 from client library.
1675 * Added cross reference of the joined channels to the
1676 SilcClientEntry, and changed the SilcChannelEntry's
1677 users list to SilcHashTable. The affected files are
1678 lib/silcclient/idlist.[ch].
1680 * Fixed a bug in hash table tarversing. While the hash table
1681 is traversed with SilcHashTableList the table must not be
1682 rehashed. It is now guaranteed that auto rehashable tables
1683 are not rehashed while tarversing the list. Also defined that
1684 silc_hash_table_rehash must not be called while tarversing
1685 the table. Added function silc_hash_table_list_reset that must
1686 be called after the tarversing is over. The affected files are
1687 lib/silcutil/silchashtable.[ch].
1689 * Changed all hash table traversing to call the new
1690 silc_hash_table_list_reset in server and in client library.
1692 * Added function silc_client_on_channel to return the
1693 SilcChannelUser entry if the specified client entry is joined
1694 on the specified channel. This is exported to application as
1695 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1697 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed founder regaining problem with JOIN command on normal
1700 server. The notify for mode change must be sent always and
1701 not only if !cmd->pending. Affected file silcd/command.c.
1703 * Fixed the WHOWAS command's reply sending to support the
1704 lists correctly. Affected file silcd/command.c.
1706 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * When sending JOIN command to router for processing the
1709 sender's old command identifier was not saved back to the
1710 sender's command context, fixed now. The affected file is
1713 * Create the key in JOIN command of the router did not return
1714 the channel key, added check for this. Affected file is
1717 * Fixed a channel ID update bug in JOIN command reply. Do
1718 not directly upgrade the ID but call the function
1719 silc_idlist_replace_channel_id if the ID was changed.
1720 Affected file silcd/command_reply.c.
1722 * Fixed memory leaks from command calling if it would fail.
1723 Affected file silcd/command.c.
1725 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1727 * Applied patches from cras:
1729 Memory leak fixes around libaries, irssi window resize fix,
1730 new silclist.h and silcdlist.h, all extern inline changed to
1733 * Removed dotconf from lib/dotconf, not needed anymore.
1735 * Removed TRQ from lib/trq, not needed anymore.
1737 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1738 with server connections. Later this will be configurable
1739 in config file after new config file is done. Affected file
1742 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1744 * Fixed a crash in server related to channel announcements.
1745 Affected file silcd/server.c.
1747 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1749 * Fixed memory leaks in silc_server_create_new_channel*
1750 functions. Affected file silcd/server.c.
1752 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1753 which ID was changed. This way the router will send the
1754 user list for the channel again, and server won't be in
1755 desync in some rare circumstances. Affected file is
1756 silcd/packet_receive.c.
1758 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1760 * Check for NULL socket pointer in the function
1761 silc_server_packet_send_to_channel_real. Affected file
1762 silcd/packet_send.c.
1764 * Fixed the BAN notify handling to correctly remove ban
1765 list. Affected file silcd/packet_receive.c.
1767 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Fixed some header addition to Toolkit distribution in
1770 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1772 * Added lib/silcclient/client_ops_example.h as an template
1773 file for application programmers to quickly start using
1774 the SilcClientOperation functions in their application.
1775 Updated the lib/silcclient/README as well to tell about this
1776 nice file made available.
1778 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1780 * Call silc_server_remove_from_channels when removing client
1781 entry when NO_SUCH_CLIENT_ID was received. Affected file
1782 is silcd/command_reply.c.
1784 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Added server & router operator statistics updating. Affected
1787 file silcd/packet_receive.c and silcd/command.c.
1789 * Fixed the SERVER_SIGNOFF notify handling on normal server
1790 not to save the history information for clients. Same was
1791 fixed earlier in remove_clients_by_server function, but not
1792 here. Affected file silcd/packet_receive.c.
1794 * Raised the default connection-retry count from 4 to 7 in
1795 server. Affected file silcd/server.h.
1797 * Cancel any possible reconnect timeouts when we start the
1798 key exchange. Affected file silcd/server.c.
1800 * Do not reconnect on connection failure when SCONNECT was
1801 given. Affected files silcd/server.[ch].
1803 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1805 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1807 * Fixed the NICK command to always give the unformatted
1808 nickname to the one giving the NICK command. If unformatted
1809 nickname is cached already it will be formatted and the
1810 local entry will always get the unformatted nickname.
1811 Affected file lib/silcclient/idlist.c.
1813 * Fixed some double frees from client library commands.
1814 Affected file is lib/silcclient/command.c.
1816 * Fixed CUMODE command in server to assure that no one can
1817 change founder's mode than the founder itself, there was a
1818 little bug. Affected file silcd/command.c.
1820 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1822 * Removed the SilcClientCommandDestructor from the client
1823 libary, it is not needed anymore. Affected files are
1824 lib/silcclient/silcapi.h, command[_reply].[ch],
1825 client_notify, idlist.c.
1827 * Fixed GETKEY command to first resolve client, and then
1828 resolve the server only if the client was not found, instead
1829 of resolving both at the same time. Affected file is
1830 lib/silcclient/command.c.
1832 * Added silc_client_start_key_exchange_cb and lookup the
1833 remote hostname and IP address before starting the key
1834 exchange with server. The affected file is
1835 lib/silcclient/client.c.
1837 * The server's public key is now saved using the IP address
1838 of the server and not the servername for the filename.
1839 The hostname public key filename is checked as an fall back
1840 method if the IP address based filename is not found.
1842 Fixed the GETKEY command to save the fetched server key
1843 in correct filename.
1845 Print the remote server's hostname now when new key is
1846 received during connection process. Affected file is
1847 irssi/src/silc/core/client_ops.c.
1849 * Return always our own public key to the client if it asks
1850 for it with GETKEY command. Affected file silcd/command.c.
1852 * Removed the use_auto_addr variable from default config
1853 file since it was in wrong section. Affected file is
1856 * Fixed TOPIC_CHANGE notification to not route it when it
1857 was sent using silc_server_send_notify_to_channel function.
1858 Affected file silcd/command.c.
1860 * Fixed silc_server_send_notify_kicked to send the kicker's
1861 Client ID also, it was missing. Affected files are
1862 silcd/command.c, silcd/packet_send.[ch].
1864 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1866 * Do not save client history information in SERVER_SIGNOFF.
1867 Fixes the bug in normal server that it does not detect
1868 the client becoming valid after the server becomes back
1869 online. Affected file silcd/server_util.c.
1871 * Added `sock_error' field into the SilcSocketConnection
1872 context. When error occurs during socket operation (read
1873 or write) the error is saved. Added also new function
1874 silc_socket_get_error to return human readable socket error
1875 message. Affected files are lib/silcutil/silcsockconn.[ch],
1876 lib/silcutil/unix/silcunixsockconn.c, and
1877 lib/silcutil/win32/silcwin32sockconn.c.
1879 * The server now prints the socket error message in the
1880 signoff for client. Affected file silcd/server.c.
1882 * Fixed the `created' channel information sending from router
1883 to server in JOIN command. Checks now whether the channel
1884 really was created or not and set it according that.
1886 Fixed the JOIN command to use the client entry's current
1887 ID during the joining procedure instead of the one it sent
1888 in the command (it is checked though), since it can change
1889 between the packet processing and command processing, and
1890 would just case unnecessary pain in the client end. Affected
1891 file silcd/command.c.
1893 * Fixed a channel key payload sending to use correct channel
1894 ID when the server was forced to change the channel's ID by
1895 router. Router sent the key payload with the old Channel ID.
1896 Affected file silcd/packet_receive.c.
1898 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1900 * Call silc_server_save_channel_key only if the key payload
1901 was provided in the JOIN command's command reply. Affected
1902 file silcd/command_reply.c.
1904 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1906 * Fixed silc_mp_sizeinbase to return the value correctly with
1907 MPI. Affected file lib/silcmath/mp_mpi.c.
1909 * Fixed the stop_server signal to correctly stop the scheduler
1910 and gracefully stop the server when SIGTERM or SIGINT signals
1911 are received. Affected file silcd/silcd.c.
1913 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1915 * Simple handling of TERM and HUP signals. Also added some log
1916 flushing call around. Affected file is
1919 * Fixed small bugs in silclog.c. Now buffering output will take
1920 effect after 10 seconds since startup: This will ensure that
1921 no important startup messages are lost. Also output redirection
1922 will preserve original format ([Date] [Type] message).
1923 Affected file is lib/silcutil/silclog.c.
1925 * Added two options to the config file, in the logging section:
1926 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1927 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1929 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1931 * Do not print the warning about log files not being initialized
1932 more than once to avoid excess logging. Affected file is
1933 lib/silcutil/silclog.c.
1935 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1936 the SIM copying in make install in Makefile.am.pre.
1938 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1940 * Rewritten silclog APIs. Globally interesting changes follows:
1941 silc_log_set_files() changed to silc_log_set_file().
1942 silc_log_set_callbacks() changed to silc_log_set_callback().
1943 ROBOdoc documented silclog header file.
1944 SilcLogCb now returns bool to wether inihibit the default
1945 handler or not (to keep the old behaviour return always TRUE).
1946 The new APIs should also fix the problem of the
1947 silcd_error.log file that was written in the current directory.
1950 Log files streams will remain opened after silc_log_set_file()
1951 call, means less CPU usage notably on high traffic servers.
1952 File streams are now full buffered, and flushed to the disk
1953 every 5 minutes, lesses HD activity and CPU usage.
1954 Messages can be redirected, allowing admins to configure
1955 one single logfile for all server messages.
1956 the silc_log_quick global variable to activate fast-logging.
1957 Affected files lib/silcutil/silclog.[ch]
1959 * Changed some code to conform new silclog APIs. Affected
1960 files are doc/example_silcd.conf.in, silcd/server.c
1961 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1964 * Fixed a memory leak that could occur in some situations.
1965 Affected file silcd/serverconfig.c.
1967 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1969 * Added the silc_client_del_client to remove the client from
1970 all channels as well. Affected file lib/silcclient/idlist.c.
1972 * Fixed the client library to correctly remove the client
1973 from all channels when the client entry is being destroyed.
1974 Affected file lib/silcclient/client_notify.c, command.c.
1976 * Added auto-nicking support to the client library. If the
1977 applicatio now sets client->nickname it will be sent to the
1978 server after connecting by the library. This way for example
1979 SILCNICK (or IRCNICK) environment variables will have effect
1980 and always change the nickname automatically to whatever
1981 it is wanted. Affected file lib/silcclient/client.[ch].
1983 * Renamed silc_server_command_bad_chars to the
1984 silc_server_name_bad_chars and moved it to the
1985 silcd/server_util.[ch]. Added also new function
1986 silc_server_name_modify_bad to return nickname that
1987 includes bad characters as new nickname without those
1988 bad characters. This check and modify is now used in
1989 silc_server_new_client when the username is initially set
1990 as nickname, so it must be checked to be valid nickname.
1991 Affected file silcd/packet_receive.c.
1993 * The nickname length is now taken from the packet for real
1994 and not trusted to strlen() since it clearly can return
1995 wrong length for nickname including bad characters. This
1996 also applies to channel names. Affected file silcd/command.c.
1998 * Removed the lib/silcsilm/modules directory. Modules are now
1999 compiled into the lib/silcsim. Fixed the copying of the
2000 modules to follow symbolic links in Makefile.am.pre.
2002 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Fixed silc_string_regexify list creation. Fixes bugs with
2005 BAN and INVITE commands in server. The affected file is
2006 lib/silcutil/unix/silcunixutil.c.
2008 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Removed the command destructor entirely from the server's
2011 command and command reply routines. It is not needed, and
2012 its usage was buggy and caused crashes. Affected files are
2013 silcd/command[_reply].[ch].
2015 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Cancel protocol and NULL sock->protocol if timeout
2018 occurred during protocol. Affected file silcd/server.c.
2020 * Cancel protocol timeouts always before calling the final
2021 callback, to assure that after final callback is called
2022 no other state will be called for the protocol anymore.
2023 Affected file silcd/protocol.c.
2025 * Print error log if incoming connection configuration could
2026 not be found. Affected file silcd/server.c.
2028 * Fixed JOIN command to correctly save the founder mode
2029 to the client on normal SILC server, when the channel
2030 was created by the router. Affected file silcd/command.c.
2032 * Fixed LIST command (hopefully) to send correct reply
2033 packets. Affected file silcd/command.c.
2035 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * The silc_packet_receive_process now returns FALSE if the
2038 read data was invalid packet, and TRUE if it was ok.
2040 The server now checks that if unauthenticated connection
2041 sends data and its processing fails the server will close
2042 the connection since it could be a malicious flooder.
2044 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2046 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Make sure the warning about error opening a log file is
2049 printed only once and not everytime it fails (produces
2050 too much useless log). Affected file lib/silcutil/silclog.c.
2052 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2054 * Made the silc_server_daemonise() function more readable.
2055 Affected file silcd/server.c.
2057 * Pid file is now optional, the user may comment it out from
2058 the config file. Removed define SILC_SERVER_PID_FILE, we
2059 don't need a default any longer. Affected file
2060 configure.in.pre, lib/Makefile.am.pre.
2062 * Make some use of the pid file. The server now dies at startup
2063 if it detects a valid pid file on his path. The server would
2064 die anyway in this circumstance, because of the bind() failure.
2065 Affected file silcd/silcd.c.
2067 * No longer compiling lib/dotconf.
2069 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Fixed JOIN command parsing not to crash. Affected file
2072 lib/silcclient/command.c.
2074 * Fied the NICK_CHANGE notify to add the new client entry
2075 even it is resolved. This removes an <[unknown]> nick
2076 thingy bug in the client. Affected file is
2077 lib/silcclient/client_notify.c.
2079 * Do not try to allocate 0 bytes (efence does not like it)
2080 in lib/silccore/silccomand.c when encoding payload.
2082 * Do not take IRCNICK as nickname in Irssi SILC client since
2083 it is not possible to set nickname before hand connecting
2084 the server (TODO has an entry about adding auto-nicking
2087 * Changed the silc_server_command_pending to check whether
2088 there already exists an pending entry with the specified
2089 command, command identifier and pending callback. This is
2090 to fix IDENTIFY and WHOIS related crashes that may register
2091 multiple pending commands with same identifier. Affected
2092 file silcd/command.c.
2094 * Fixed the server to reconnect to the router even if it
2095 was already reconnecting and EOF was received. This to
2096 fix a possibility that the server wouldn't ever try to
2097 auto-reconnect to the router. Affected file silcd/server.c.
2099 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Fixed the server's password authentication to use the
2102 length of the locally saved password, and not the one
2103 sent in the packet. Affected file silcd/protocol.c.
2105 * Fixed same password authentication problem in the
2106 Authentication Payload handling routines in
2107 lib/silccore/silcauth.c.
2109 * Yet another password authentication problem fixed with
2110 channel password handling in silcd/command.c.
2112 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * If first character of string in silc_parse_userfqdn is '@'
2115 then do not parse it. Affected file is
2116 lib/silcutil/silcutil.c.
2118 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Fixed minor bug in IDENTIFY command reply sending, which
2121 caused various weird problems during JOIN when it was
2122 resolving names for users. Affected file silcd/command.c.
2124 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Fixed the IDENTIFY command reply sending to chech better valid
2127 clients. It was possible to send incomplete list of replies.
2128 Affected file silcd/command.c.
2130 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2132 * Added silc_client_command[s]_[un]register functions now to
2133 dynamically register the commands in client library. Removed
2134 the static table of commands. This allows the client library
2135 to call commands without causing the application to know about
2136 what commands library has called.
2138 Removed the INFO command reply kludge to detect when the command
2139 was called by library. Now library use its own command reply
2140 function for INFO command.
2142 Added function silc_client_command_call to call a command.
2143 Application can use it to call command, not access the structure
2146 Now all commands that are sent by the client library (not
2147 explicitly sent by application) use own command reply functions.
2149 Affected files around lib/silcclient/ and in
2150 irssi/src/silc/core/.
2152 * Fixed the WHOIS command reply sending to chech better valid
2153 clients. It was possible to send incomplete list of replies.
2155 Fixed the WHOIS and IDENTIFY to send the request to router
2156 if normal server did not do it and did not find any results.
2158 Affected file silcd/command.c.
2160 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Moved the internal data from SilcClient context into its
2163 own file, not accesible to application. Affected files
2164 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2165 and other files in client library.
2167 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Added doc/examples installation target in Makefile.am.pre.
2172 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2175 commands the found client entry will be removed from the
2176 cache, after notifying application about the error. Affected
2177 file lib/silcclient/command_reply.c.
2179 * Changed the /MSG to check for exact nickname user gave, and
2180 not let `nick' match `nick@host' if it is only one found. Now,
2181 user must type the exact nickname (like nick@host2) even if
2182 there are no more than one same nicks found. This is to avoid
2183 a possibility of sending nickname to wrong nickname since
2184 `nick' could match `nick@host'. Affected file is
2185 irssi/src/core/silc-servers.c.
2187 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Do not print "you are now server operator" or similar when
2190 giving /away command. Affected files are
2191 irssi/src/silc/core/client_ops.c, silc-servers.h.
2193 * Made the silc_server_command_pending_error_check to send
2194 the same command reply payload it received back to the
2195 original sender of the command. This way all arguments
2196 that was received by the server will be received by the
2197 client too. Affected file silcd/command.c.
2199 * Added the silc_idcache_add to return the created cache entry
2200 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2202 * Add global clients to expire if they are not on any channel.
2203 This is because normal server will never know if they signoff
2204 if they are not on any channel. The cache expiry will take
2205 case of these entries. This is done by normal servers only.
2206 The affected files are silcd/command_reply.c,
2207 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2209 * If server receives invalid ID notification for WHOIS or
2210 IDENTIFY and the ID exists in the lists, it is removed.
2211 Affected file silcd/command_reply.c.
2213 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2214 in client then client entry that it matches is searched and
2215 the nickname is printed on the screen for user. Affected
2216 file irssi/src/silc/core/client_ops.c.
2218 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Use cache entry expire time in the LIST command reply to
2221 purge old entries from the cache after the LIST command
2222 reply has been received. This way we don't have non-existent
2223 entries in the cache for too long. Affected file is
2224 silcd/command_reply.c.
2226 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * If we are normal server, and we've not resolved client info
2229 in WHOIS or IDENTIFY from router, and it is global client,
2230 we'll check whether it is on some channel. If it is not
2231 then we cannot be sure about its validity and will resolve it
2232 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2233 file silcd/command.c.
2235 * Search channel by name (if possible) rather than by ID
2236 in IDENTIFY command's command reply. Affected file is
2237 silcd/command_reply.c.
2239 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2242 Updated specs and implemented it. Affected file silcd/command.c,
2243 silcd/packet_send.c and silcd/packet_receive.c.
2245 * Implemented the <founder auth> payload handling in the JOIN
2246 command. If provided all conditions for channel joining
2247 except requirement to provide correct passphrase can be
2248 overrided by the channel founder. Updated the protocol specs.
2249 Affected file silcd/command.c.
2251 Added support for founder auth in JOIN command in client
2252 library. Fixed the parsing of the JOIN command now to support
2253 all options as they should be. The affected file is
2254 lib/silcclient/command.c.
2256 * Optimized the WHOIS and IDENTIFY commands to send the request
2257 to router only if it includes nicknames or other names. If
2258 they include only IDs then check the local cache first before
2259 routing. Affected file is silcd/command.c.
2261 * Added channels topic announcements. Affected file is
2262 silcd/packet_receive.c and silcd/server.c.
2264 * Fixed the silc_server_send_notify_topic_set to really destine
2265 the packet to channel. Affected file silcd/packet_send.c.
2267 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2268 library. Affected file lib/silcclient/client_notify.c.
2270 * Added UMODE announcements. Affected file silcd/server.c.
2272 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Memory leak fixes in:
2276 lib/silcutil/silcsockconn.c
2277 lib/silcske/silcske.c
2278 lib/silcske/groups.c
2280 lib/silccrypt/silcpkcs.c
2281 lib/silccore/silccommand.c
2282 lib/silccore/silcidcache.c
2287 * ROBOdoc documented the lib/silcske/groups.h file and a
2288 bit changed the interface for better.
2290 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2292 * Update the client entry context in the ID cache after
2293 nick change. Affected file lib/silcclient/command.c.
2294 Fixes the CUMODE command when regaining founder privileges,
2295 and a little WHOIS problem.
2297 * Fixed silc_net_gethostbyname to correctly call the
2298 inet_ntop. Affected file lib/silcutil/silcnet.c.
2300 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2302 * Added IPv6 support checking to the configure.in.pre, added
2303 also --enable-ipv6 option to override the check. Affected
2304 file configure.in.pre.
2306 * The silc_thread_create now calls the start function
2307 directly if threads support is not compiled in. Removes
2308 ugly #ifdef's from generic code. Affected files are
2309 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2311 * Added silc_net_gethostby[name/addr]_async to asynchronously
2312 resolve. Affected files are lib/silcutil/silcnet.[ch].
2314 * Added support for rendering IPv6 based server, client and
2315 channel IDs. Affected file lib/silcutil/silcutil.c.
2317 * Added support for creating IPv6 based server IDs. Affected
2318 file is silcd/serverid.c.
2320 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2322 * Added silc_net_gethostby[addr/name] into the
2323 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2324 routines. Added silc_net_is_ip[4/6]. Affected file is
2325 lib/silcutil/unix/silcunixnet.c. All routines that take
2326 address as argument now supports both IPv4 and IPv6 addresses.
2328 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2330 * Fixed LIST command reply sending in server. Affected file
2333 * Server now sends the kicker's client ID in the KICK notify
2334 to the kicked client. Affected file silcd/command.c.
2336 * The client library now parses the kickers client ID and
2337 UI displays it. Affected files lib/silcclient/client_notify.c
2338 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2340 * Made all payload parsing function prototypes consistent.
2341 They all take now const unsigned char * and uint32 pair as
2342 the payload data instead of SilcBuffer. Changes all around
2343 the source tree. Other unsigned char* -> const unsigned char*
2344 changes around the tree as well.
2346 * Optimized SFTP client and server packet sending not to
2347 allocate new buffer for each packet but to recycle the
2348 first allocated buffer. Affected files are
2349 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2351 * Optimized the SFTP client to use SilcList instead of
2352 SilcDList for requests, because it is faster. Affected file
2353 is lib/silcsftp/sftp_client.c.
2355 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2356 into lib/silccore/silcid.[ch].
2358 Renamed silcpayload.[ch] into silcargument.[ch].
2360 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * If client entry is deleted with active key agreement
2363 session, abort the session.
2365 The silc_client_abort_key_agreement now calls the completion
2366 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2368 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2371 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Don't use __restrict in older GCC's. Affected file is
2374 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2376 * silc_net_localhost now attempts to reverse lookup the
2377 IP/hostname. Affected file lib/silcutil/silcnet.c.
2379 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2380 command. It can be used to gain founder privileges at
2381 the same time when joining the channel.
2383 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2384 kicker's client ID as well. Updated protocol specs.
2386 Defined that the server must send SILC_COMMAND_IDENTIFY
2387 command reply with error status to client who sent
2388 private message with invalid client ID.
2390 Updated the protocol specification.
2392 * Added silc_server_send_command_reply to send any
2393 command reply. Affected file silcd/packet_send.[ch].
2395 * Added silc_id_payload_encode_data to encode ID payload
2396 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2398 * The server now send IDENTIFY command reply with error
2399 status if client ID in private message is invalid. Affected
2400 file silcd/packet_receive.c.
2402 * Save the server key file with server's IP address in
2403 the filename instead of hostname. The affected file is
2404 irssi/src/silc/core/client_ops.c.
2406 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2411 * Added libtool support for compiling shared objects in
2412 lib/silcsim. Affected file configure.in.pre and
2413 lib/silcsim/Makefile.am. Original patch by cras.
2415 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Pid file configuration, and server's config file fixes
2418 patch by toma. Updated CREDITS file.
2420 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Fixed silc_client_channel_message to not try to decrypt
2423 the message twice if it resolved the destination client
2424 information. This could cause of dropping one channel
2425 message. Affected file lib/silcclient/client_channel.c.
2427 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2430 lib/silcclient/client.c. This function is used when the SILC
2431 Client is run under some other scheduler, or event loop or
2432 main loop. On GUI applications, for example this may be
2433 desired to used to run the client under the GUI application's
2434 main loop. Typically the GUI application would register an
2435 idle task that calls this function multiple times in a second
2436 to quickly process the SILC specific data.
2438 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2440 * Fixed silc_server_drop() for dropping the supplementary
2441 groups as well, this could cause a security hole on some
2444 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2449 * Write PID file after dropping privileges. Added -F option
2450 to run server on foreground. A patch by debolaz.
2451 Affected files silcd/server.c, silcd/silcd.c.
2453 * Fixed MOTD to return the MOTD file server name. Affected
2454 file silcd/command.c.
2456 * Added INFO command reply handling to the Irssi SILC Client.
2457 Affected file irssi/src/silc/core/client_ops.c.
2459 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Fixed the silc_idcache_list_* routines to really support
2462 the dynamic list. Fixes a crash. Affected file is
2463 lib/silccore/silcidcache.c.
2465 * Fixed the LIST command reply to really call LIST command's
2466 pending callbacks. Affected file silcd/command_reply.c.
2468 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Update conn->local_entry->nickname after giving NICK
2471 command. Affected file lib/silcclient/command.c.
2473 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2475 * Added the [pid] option to the silcd configuration file
2477 Affected files: serverconfig.[ch] and silcd.c
2479 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * Save fingerprint in WHOIS command reply in server.
2482 Affected file silcd/command_reply.c.
2484 * Fixed NICK commands pending callback registration.
2485 Affected file lib/silcclient/command.c.
2487 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Use ++server->cmd_ident when sending commands in server,
2490 instead of random number. Affected file silcd/command.c.
2492 * Fixed GETKEY command reply to call actually GETKEY pending
2493 command callbacks. Affected file silcd/command_reply.c.
2495 * A bit stricter check for nicknames. Check for same nickname
2496 in NICK command also. Affected file silcd/command.c.
2498 * Do not call INFO command everytime client ID changes, only
2499 during first connecting. Affected file lib/silcclient/client.c.
2501 * Set the new nickname only after successful command reply for
2502 NICK command is returned by server. Affected file
2503 lib/silcclient/command.c.
2505 * Remove nicknames from nicklist during server_signoff notify.
2506 Should fix /NAMES bit more. The affected file is
2507 irssi/src/silc/core/silc-channels.c.
2509 * Added `fingerprint' field to the SilcIDListData in the
2510 silcd/idlist.h to hold the fingerprint of the client's
2513 Send the fingerprint of the client's public key in WHOIS
2516 Affected files silcd/command.c, and silcd/idlist.[ch].
2518 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2519 create fingerprint from given data.
2521 * Show the fingerprint of the client's public key in WHOIS.
2522 Affected files irssi/src/module-formats.[ch] and
2523 irssi/src/silc/core/client_ops.c.
2525 * Format the multiple same nicknames also during JOIN and
2526 NICK_CHANGE notifys. Affected file is
2527 lib/silcclient/client_notify.c.
2529 * Do not print error on screen for invalid private message
2530 payload since it can come if someone is sending private
2531 messages with wrong key. Affected file
2532 lib/silccore/silcprivate.c.
2534 * Fixed multiple concurrent /PING crash. Affected file
2535 lib/silcclient/command.c.
2537 * Changed the wrong ID encoding. All IP addresses must be
2538 in MSB first order in encoded format. They were encoded
2539 wrong and was in LSB format. Affected files are
2540 silcd/serverid.c, lib/silcutil/silcutil.c.
2542 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2544 * Call the `connect' client operation through the scheduler
2545 in case of error. Affected file lib/silcclient/client.c.
2547 * Call the `failure' client operation even if the error
2548 occurred locally during a protocol. Affected file is
2549 lib/silcclient/protocol.c.
2551 * Added support of sending LIST command to router from normal
2552 server. This way normal server can get list of all channels
2553 in the network too. Fixed the channel list sending in the
2554 server too. Affected files are silcd/command.c, and
2555 silcd/command_reply.[ch].
2557 * Added silc_server_update_channels_by_server and
2558 silc_server_remove_channels_by_server. They are used during
2559 disconnection of primary router and in backup router protocol.
2560 Affected file silcd/server_util.[ch], silcd/server.c and
2561 silcd/server_backup.c.
2563 * Fixed channel adding to global list in IDENTIFY command
2564 reply in server. Affected file silcd/command_reply.c.
2566 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * If the incoming packet type is REKEY or REKEY_DONE process
2569 that packet always synchronously. Fixes yet another MAC
2570 failed error on slow (dialup) connections. Affected file
2571 lib/silcclient/client.c and silcd/server.c.
2573 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Call check_version SKE callback for initiator too. Affected
2576 file lib/silcske/silcske.c.
2578 * Implemented fix for security hole found in the SKE that was
2579 fixed in the specification few days back; the initiator's
2580 public key is now added to the HASH value computation.
2581 Added backwards support for the old way of doing it too, for
2582 old clients and old servers. Affected file is
2583 lib/silcske/silcske.c.
2585 * Enabled mutual authentication by default in SKE. If initiator
2586 is not providing mutual authentication the responder will
2587 force it. This will provide the proof of posession of the
2588 private key for responder. The affected files are
2589 lib/silcclient/protocol.c and silcd/protocol.c.
2591 * Do not cache anymore the server's public key during SKE.
2592 We do mutual authentication so the proof of posession of
2593 private key is done, and if the server is authenticated in
2594 conn auth protocol with public key we must have the public
2595 key already. Affected file silcd/protocol.c.
2597 * Added new global debug variable: silc_debug_hexdump. If
2598 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2599 file lib/silcutil/silclog.[ch].
2601 * Fixed compilation warning due to char * -> const char *.
2602 Affected files lib/silcutil/silcnet.h, and
2603 lib/silccore/silcauth.[ch].
2605 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Fixed CMODE command when new channel key was created. If
2608 the creation failed the old key was removed. Next time giving
2609 same command would crash the server since the old key was
2610 freed already. Affected file silcd/command.c.
2612 * Fixed the silc_server_announce_get_channels to not crash
2613 on reconnect. Affected file silcd/server.c.
2615 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Added silc_log_set_debug_string function to set a regex
2618 string to match for debug output. Only the function names,
2619 or filenames matching the given debug string is actually
2620 printed. This way it is possible to filter out those debug
2621 strings that user is not interested in.
2623 Fixed a bug in silc_string_regexify.
2625 Affected files lib/silcutil/silclog.[ch], and
2626 lib/silcutil/unix/silcunixutil.c.
2628 * Changed the -d options in both server and Irssi SILC client
2629 to take the debug string as argument. Affected files
2630 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2632 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added silc_hash_babbleprint to create a Bubble Babble
2635 Encoded fingerprint. The encoding is developed by Antti
2636 Huima (draft-huima-babble-01.txt), and it creates human
2637 readable strings out of binary data. Affected file
2638 lib/silccrypt/silchash.[ch].
2640 * Print the babble print now in addition of fingerprint as well
2641 in Irssi SILC client. Affected files are
2642 irssi/src/fe-common/silc/module-formats.[ch],
2643 irssi/src/fe-common/silc/core/client_ops.c.
2645 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Fixed a security problem found in SKE. The initiator's
2648 public key too is now added to the HASH hash value creation
2649 which is signed by the responder to create the SIGN value.
2650 This will prevent anyone in the middle to lie to the responder
2651 about the initiator's public key. If this is done now, the
2652 man in the middle will get caught. Updated the protocol
2655 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Better installation directory handling. Configure module
2658 paths and other paths automatically to example_silc* files
2659 in doc/. A patch by toma.
2661 * Fixed compiler warning from MPI library, and from SILC RNG.
2664 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2665 It can be configured with ./configure. A patch by toma.
2667 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Find correct make to use in prepare-clean. A patch by
2670 toma. Affected file prepare-clean.
2672 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2674 * Added irssi variables use_auto_addr, auto_bind_ip,
2675 auto_bind_port and auto_public_ip.
2677 * Changed the interface for silc_client_send_key_agreement
2678 in lib/silcclient/silcapi.h
2682 irssi/src/silc/core/silc-core.c
2684 lib/silcclient/silcapi.h
2685 irssi/src/silc/core/silc-channels.c
2686 lib/silcclient/client_keyagr.c
2689 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added silc_pkcs_public_key_compare to compare two
2692 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2694 * Check that the client who set the founder mode on the
2695 channel is the same client that is giving the founder
2696 mode to itself. It is done by comparing the saved public
2697 key (it is saved even in the authentication is passphrase).
2698 Affected file silcd/command.c.

2705 * Process the DISCONNECT packet through scheduler in the
2706 client library. Affected file lib/silcclient/client.c.
2708 * Fixed the silc_client_packet_parse to not to increase
2709 the packet sequence number if the conn->sock and the
2710 current socket connection is not same. This can happen
2711 for example during key agreement when the conn includes
2712 multiple socket connections (listeners). Affected file
2713 lib/silcclient/client.c.
2715 * The sender of the file transfer request now provides also
2716 the pointer (listener) for the key exchange protocol. If
2717 the listener cannot be created then it sends empty key
2718 agreement and lets the receiver provide the listener.
2720 Added `local_ip' and `local_port' arguments to the
2721 silc_client_file_send. If they are provided they are used,
2722 if not then it will attempt to find local IP address, if
2723 not found or bind fails then the remote client will provide
2726 Affected files are lib/silcclient/client_ftp.c and
2727 lib/silcclient/silcapi.h.
2729 * Extended the FILE SEND command to support defining the
2730 local IP and port for key exchange listener. They are
2731 optional. Affected file irssi/src/silc/core/silc-servers.c.
2733 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Defined to WHOIS command reply the sending of fingerprint
2736 of the client's public key (if the proof of posession of the
2737 corresponding private key is verified by the server).
2738 Updated to the protocol specification.
2740 * Added support of receiving the client's public key's
2741 fingerprint in command reply in client library. Affected
2742 file is lib/silcclient/command_reply.c, and
2743 lib/silcclient/idlist.[ch].
2745 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2748 in NICK command. Affected file lib/silcclient/command.c.
2750 * Do not send over 256 chars long channel names to the server
2751 in JOIN command. Affected file lib/silcclient/command.c.
2753 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Assure that silc_server_close_connection cannot be called
2756 twice for same socket context. Affected file is
2759 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Send error message to application if opening file for
2762 writing during file transfer fails. Affected file is
2763 lib/silcclient/client_ftp.c.
2765 Remove all file transfer sessions for a client that we're
2766 removing from ID cache.
2768 Affected file is lib/silcclient/client_ftp.c.
2770 * Fixed silc_net_addr2bin to return correct address. Affected
2771 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2773 * Fixed file transfer session removing on signoff notify.
2774 Affected file irssi/src/silc/core/silc-servers.c.
2776 * Added the SilcClientFileError to be returned in the monitor
2777 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2778 Affected file lib/silcclient/silcapi.h.
2780 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2798 client library. Affected file lib/silcclient/client_prvmsg.c.
2800 * Do not actually remove the client directly from ID cache
2801 during SERVER_SIGNOFF, but invalidate it. This way we
2802 preserve the WHOWAS info for the client. Affected file
2803 silcd/server_util.c.
2805 * Fixed SERVER_SIGNOFF notify handling in the server. The
2806 server is now able to process incoming SERVER_SIGNOFF notify
2807 for a server that it doesn't even know about. It will remove
2808 the clients provided in the notify. Affected file
2809 silcd/packet_receive.c.
2811 * Check for partial packet in data queue after every packet that
2812 was found from the queue. Return and wait for more data if
2813 there is partial data in queue. Affected file is
2814 lib/silccore/silcpacket.c.
2816 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Added SilcClietFileError enum to indicate error in
2819 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2820 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2821 Affected files lib/silcclient/silcapi.h and

2824 * Check that newsize in silc_buffer_realloc is larger than
2825 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2827 * Added better monitor of file transfers. It now monitors
2828 key agreement protocol during the file transfer too. Added
2829 error reporting too. Affected files
2830 irssi/src/silc/core/silc-servers.c,
2831 irssi/src/fe-common/silc/module-formats.[ch].
2833 * Wrote a help file for FILE command.
2835 * Added silc_rng_global_get_byte_fast to get not-so-secure
2836 random data as fast as possible. Random data is read from
2837 /dev/urandom if available and from the SILC RNG if not
2838 available. It is used in padding generation. Affected file
2839 lib/silccrypt/silcrng.[ch].
2841 * All packets in client library are now processed synchronously.
2842 Optimized packet processing a lot. Affected file
2843 lib/silcclient/client.c.
2845 * All server connection packets are processing synchronously
2846 now in server, to optimize packet processing. Affected file
2849 * Include files are installed now only in Toolkit distribution
2850 if make install is given. Affected files: all Makefile.am's.
2852 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Assure that silc_client_notify_by_server_resolve does not
2855 resolve the client information multiple times. If it cannot
2856 be found by the first it cannot be found at all. Affected
2857 file lib/silcclient/client_notify.c.
2859 * Fixed WHOWAS command reply calling. Affected file
2860 lib/silcclient/command_reply.c.
2862 * Removed all references to silc_idlist_get_client from the
2863 Irssi SILC client since that call is internal call used by
2864 the library. The Irssi SILC client will use now client
2865 retrieval functions found in silcapi.h.
2867 * Fixed a bug in resolving nickname info before sending
2868 private message. It used freed memory. Affected file
2869 irssi/src/silc/core/silc-servers.c.
2871 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Assure my_channels statistics cannot go negative in server.
2874 Affected files silcd/server.c, silcd/server_util.c.

2890 * Added silc_net_localip to return local host's IP address.
2891 Affected file lib/silcutil/silcnet.[ch].
2893 * If key exchange or rekey protocol is active for a connection
2894 parse all packets syncronously since there might be packets
2895 in packet queue that we are not able to process without first
2896 processing packets before them. Affected file silcd/server,
2897 lib/silcclient/client.c.
2899 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2900 whether library should continue processing the packet.
2901 Affected file lib/silccore/silcpacket.h.
2903 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2904 SilcSFTPMonitorData to SFTP server to monitor various
2905 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2942 file irssi/src/silc/core/silc-channels.c.
2944 * Added SilcClientStatus field to the SilcClientEntry in the
2945 lib/silcclient/idlist.h.
2947 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2948 is incomplete and is being resolved, it won't be resolved
2951 Make sure also that USERS command reply does not resolve
2952 twice information. Affected file is
2953 lib/silcclient/command_reply.c.
2955 Make sure that silc_client_get_clients_by_list does not
2956 resolve twice same information.
2958 * Check for valid client->id in the silc_server_free_client_data.
2959 Affected file silcd/server.c.
2961 * Fixed /GETKEY nick@server not to crash if the server entry
2962 is not found. Affected file lib/silcclient/command.c.
2964 * Fixed the silc_server_check_cmode_rights to check the
2965 requested modes correctly. Affected file silcd/command.c.
2967 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Better checks for non-printable chars in nick added.
2970 Affected file silcd/command.c.
2972 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Call the silc_server_udpate_servers_by_server in the
2975 primary router that comes back online in the backup resuming
2976 protocol. Otherwise it routes packets wrong. Affected file
2977 silcd/server_util.[ch], silcd/server_backup.c.
2979 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2982 lib/silcutil/silcbuffmt.[ch].
2984 * Redefined the SILC packet header to include the padding
2985 length. Affected file lib/silccore/silcpacket.[ch].
2987 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2988 length for maximum padding up to 128 bytes). Affected
2989 file lib/silccore/silcpacket.h.
2991 * Removed all backwards support for old 0.5.x MAC thingies.
2992 The SILC packet header change makes it impossible to be
2993 backwards compatible.
2995 * Send the ENDING packet with timeout in the backup resuming
2996 protocol. This is to assure that all routers has connected
2997 to the primary router. Affected file silcd/server_backup.c.
2999 * Changed the RNG to take the first IV from random data. It
3000 used to take it from zero actually. Changed the RNG also
3001 to use /dev/urandom during session. /dev/random is used
3002 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3004 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Changed the SILC packet header to have the first two bytes
3007 (the packet length) encrypted. Affected files aroung the
3008 code tree, lib/silccore/silcpacket.[ch]. Removed the
3009 SilcPacketCheckDecrypt callback. It is not needed anymore
3010 since the silc_packet_receive_process will determine now
3011 whether the packet is normal or special.
3013 * Implemented the unidirectional MAC keys. Affected files
3014 lib/silcske/silcske.c, silcd/protocol.c and
3015 lib/silcclient/protocol.c.
3017 * Implemented the packet sequence number to the MAC computation.

3022 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Allow backup router to announce servers. All servers
3025 announced by backup router are added to the global list
3026 automatically. Update hte server's socket to our primary
3027 router also when backup router announces a server.
3028 Affected file silcd/packet_receive.c.
3030 * Do not update the client->router in the function
3031 silc_server_udpate_clients_by_server if the client is on
3032 global list. We might fail to find any specific server
3033 for locally connected clients and local cell clients. They
3034 should still use the `from' and not `to' as client->router.
3035 This fixes backup router resuming protocol. Affected file
3036 silcd/server_util.c.
3038 * Decrease channel statistics count only if the channel
3039 deletion worked. Affected files are silcd/server.c and
3040 silcd/server_util.c.
3042 * Added silc_server_update_servers_by_server to update origin
3043 of all server entries. Used during backup router protocol.
3044 Affected files silcd/server_util.[ch], silcd/server.c. and
3045 silcd/backup_router.c.
3047 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3048 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3049 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3050 lib/silccrypt/silchmac.c.
3052 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Assure that router cannot reroute the same channel message
3055 to the sender. Affected file silcd/packet_receive.c.
3057 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Made better checks that the channel message is not sent
3060 to the router it came from. Affected file is
3061 silcd/packet_send.c. Fixed memory leak too.
3063 * Announce informations for incoming router connection, but
3064 only after checking if it is replaced by backup router.
3065 Affected file silcd/packet_receive.c.
3067 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Fixed the backup resuming protocol to work in multiple
3070 router environment. Affected file silcd/server_backup.c.
3072 * Route packet only to one router in the function
3073 silc_server_packet_send_to_channel. Affected file is
3074 silcd/packet_send.c.
3076 * Fixed silc_server_send_notify_dest to set the broadcast
3077 flag. Fixed the silc_server_send_notify_topic to actually
3078 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3079 Affected file silcd/packet_send.c.
3081 * Changed the SFTP Filesystem interface. Changed the
3082 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3083 the filesystem operation function. The SilcSFTPFilesystem
3084 is now a context that is allocated by all filesystem allocation
3085 functions and it already includes the operations structure
3086 and filesystem specific context. It is given as argument
3087 now to the silc_sftp_server_start. This made the interface
3088 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3089 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3091 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Changed the backup router adding and getting interfaces
3094 in the server. The router that will be replaced by the
3095 specified backup router is now sent as argument. Affected
3096 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3099 * Added silc_net_addr2bin_ne to return the binary form of
3100 the IP address in network byte order. Affected files
3101 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3103 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3105 * Check for existing server ID in silc_server_new_server
3106 and in silc_server_connect_to_router_final and remove the
3107 old entry if it exists. Affected file silcd/packet_receive.c,
3110 * Send the channel message always to only one router, either
3111 in upstream or downstream. Affected file is
3112 silcd/packet_send.c.
3114 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Wrote the definition of the backup resuming protocol to the
3117 protocol specification.
3119 * Removed one redundant channel key generation from normal
3120 server during joining procedure. Removed one redundant
3121 channel key sending from server to router during joining
3122 procedure. Affected file silcd/command.c.
3124 * Made minor bugfixes to the backup router resuming protocol.
3125 Affected file silcd/server_backup.c, server.c.
3127 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Added --disable-asm configuration option. Affected files
3130 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3133 * Implemented the backup resuming protocol that is used to
3134 resume the primary router position in the cell after the
3135 primary router comes back online. Affected files
3136 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3137 and silcd/server_util.[ch].
3139 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Sleep two (2) seconds after sending QUIT command to server.
3142 Affected file lib/silcclient/command.c.
3144 * Assure that if outgoing data buffer is pending do not force
3145 send any data. Affected file silcd/packet_send.c.
3147 * Assure that if outgoing data buffer is pending do not force
3148 send any data. Affected file lib/silcclient/client.c.
3150 * Implemented the backup router support when the primary router
3151 goes down. The servers and routers can now use the backup
3152 router as new primary router without loosing connectivity.
3154 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3157 in the server to indicate disabled entry. All data read
3158 from the connection will be ignored and no data is sent
3159 for entry that is disabled. Affected files are
3160 silcd/idlist.h, silcd/server.c.
3162 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3164 * Created SFTP client and server test programs in the
3165 lib/silcsftp/tests directory.
3167 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3169 * Implemented memory filesystem (virtual filesystem) for
3170 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3173 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Implemented the SFTP (SSH File Transfer Protocol) to the
3176 lib/silcsftp. It includes SFTP client and SFTP server
3179 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Moved lib/silccore/silcprotocol.[ch] to the
3182 lib/silcutil library.
3184 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3185 take variable argument list pointer as argument. Affected
3186 file lib/silcutil/silcbuffmt.[ch].
3188 * Added silc_buffer_set function that is used to set data
3189 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3190 Affected file lib/silcutil/silcbuffer.h.
3192 * Changed various routines in the core library to use the new
3193 silc_buffer_set instead of allocating new buffer only for
3196 * Added 64-bit value formatting and unformatting support to the
3197 silc_buffer_[un]format routines. Affected file is
3198 lib/silcutil/silcbuffmt.[ch].
3200 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3201 to includes/bitmove.h.
3203 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Fixed channel user mode saving in client library. Affected
3206 file lib/silcclient/command[_reply].c.
3208 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Defined the file transfer to the SILC Protocol. Added
3211 new packet type SILC_PACKET_FTP and defined File Transfer
3212 Payload. The mandatory file transfer protocol is SFTP
3213 (SSH File Transfer Protocol). Affected file in addition
3214 of the internet draft is lib/silccore/silcpacket.h.
3216 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3217 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3218 is used as part of backup router protocol when the primary
3219 router of the cell is back online and wishes to resume
3220 the position as primary router.
3222 * Redefined the MAC generation keys in the protocol. The
3223 same key is not used anymore in both direction. Both
3224 direction will now use different keys for sending and
3225 receiving. This fixes a potential security flaw. This
3226 change causes incompatibilities in the protocol.
3228 * Redefined also the MAC computation from the packet.
3229 An packet sequence number is now added to the MAC
3230 computation. This prevents possible replay attacks against
3231 the protocol. This change too causes incompatibilities
3234 Added `sequence' field to the SilcPacketContext to hold
3235 the current sequence number for the packet.
3237 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * Added `created' field to the SilcIDListData in the file
3240 silcd/idlist.h to indicate the time when the entry was
3243 * Added `created' field to the SilcChannelEntry too. Affected
3244 file silcd/idlist.h.
3246 * Added `creation_time' aguments to all the announcement functions
3247 in the server. If it is provided then only the entries that
3248 was created after the provided time frame are actually
3249 announced. Affected file silcd/server.[ch].
3251 * The protocol says that the Channel ID's IP address must be
3252 based on the router's IP address. Added check for this in
3253 the silc_server_new_channel when processing incoming New Channel
3254 Payload. Affected file silcd/packet_receive.c.
3256 * Print out the correct version with --version in SILC client.
3257 Affected file irssi/src/silc/core/silc-core.c.
3259 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Fixed WHOWAS command to check for completnes of the client
3262 entry always, not just when the command is coming from client.
3263 Affected file silcd/command.c.
3265 * Added new function silc_server_packet_queue_purge to purge the
3266 outgoing data queue to the network. After the function returns
3267 it is guaranteed that the outgoing packet queue is empty.
3268 Affected file silcd/packet_send.[ch].
3270 * Purge the outgoing packet queue in the rekey protocol's final
3271 callback to assure that all rekey packets go to the network
3272 before quitting the protocol. Affected file silcd/server.c.
3274 * Added silc_client_packet_queue_parse as similar function as
3275 in server to the client library. The affected file is
3276 lib/silcclient/client.c.
3278 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Splitted silcd/server.c and created silcd/server_util.[ch]
3281 for utility functions.
3283 * Added new socket flag SILC_SF_DISABLED to indicate that the
3284 connection is open but nothing can be sent to or received from
3285 the connection. Affected file lib/silcutil/silsockconn.[ch].
3286 The checking for disabled socket is checked in the low level
3287 silc_socket_write and silc_socket_read functions.
3289 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Allow only nicknames and channel names that fits into the
3292 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3294 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * When processing JOIN command reply in server check that if
3297 the channel exists in our global list we'll move it the local
3298 list. Affected file silcd/command_reply.c.
3300 * Fixed the check whether client is joined on the channel already
3301 in JOIN command. Affected file lib/silcclient/command.c.
3303 * Fixed the JOIN command reply to check whether the channel
3304 already exists. Affected file lib/silcclient/command_reply.c.
3306 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Added silc_ske_status_string to map the SKE error numbers
3309 to readable strings. The affected files are
3310 lib/silcske/silcske[_status].[ch].
3312 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Do not show the private channels on the WHOIS channel list
3315 as it is not allowed by the protocol. The affected file is
3318 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Assure that the packet length digged from the actual packet
3321 is something sensible in the silc_packet_decrypt_rest_special
3322 in lib/silccrypt/silcpacket.c.
3324 * Free and NULL the allocated pointer in silc_hmac_alloc if
3325 the HMAC allocation fails. The affected file is
3326 lib/silccrypt/silchmac.c.
3328 * Print the selected security properties to the log files in
3329 the server. Affected file silcd/protocol.c.
3331 * Add SKE's reference counter even if calling the completion
3332 callback manually. Otherwise it goes negative, although it
3333 does not cause any problems. The affected file is
3334 lib/silcske/silcske.c.
3336 * Remove the client entry with short timeout after giving the
3337 KILL command. Affected file lib/silcclient/command.c.
3339 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3340 case all found clients are already disconnected (WHOWAS would
3341 found them) in the server. Affected file silcd/command.c.
3343 * Update the last_receive (time of last data received) to be
3344 updated only when received private or channel message so that
3345 the idle time showed in WHOIS makes more sense.
3347 * Added boolean field `valid' in to the SilcClientEntry in the
3348 client library to indicate whether the entry is valid or not.
3349 This fixes the nickname change bug on channel when changing
3350 the nickname to be same than the old (like nick to Nick) the
3351 nickname formatter doesn't set the new nick anymore to Nick@host.
3352 Affected file lib/silcclient/idlist.[ch].
3354 * Now actually fixed the nickname changing on disconnection.
3355 Added new function silc_change_nick to the Irssi SILC Client.
3356 Affected file irssi/src/silc/core/client_ops.c,
3357 irssi/src/silc/core/silc-nicklist.[ch].
3359 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Check that the public key exists in the GETKEY command before
3362 trying to encode it. Affected file silcd/command.c.
3364 * Print some notifications on received public keys with GETKEY
3365 command in the Irssi SILC Client. Affected files are
3366 irssi/src/fe-common/silc/module-formats.[ch],
3367 irssi/src/silc/core/client_ops.c.
3369 * Use IDENTIFY command to resolve the server information in the
3370 GETKEY command instead of INFO command. Affected file
3371 lib/silcclient/command.c.
3373 * All command reply functions in the client library now calls
3374 the pending command reply callbacks even if an error has
3375 occurred. The server has done this a long time and now it was
3376 time to move the client library to this as well. Now all
3377 errors can be delivered back to the pending command reply
3378 callbacks if necessary. Affected files are
3379 lib/silcclient/command[_reply].[ch].
3381 * Change the nickname on disconnection back to the username
3382 because in reconnect the server will enforce it to it anyway.
3383 Affected file irssi/src/silc/core/silc-servers.c.
3385 * Fixed a config file parsing bug in the Irssi SILC client.
3386 Affected file irssi/src/silc/core/clientconfig.c.
3388 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * When printing the channel mode on JOIN, verify that the
3391 channel key and channel's HMAC are valid. Affected file
3392 irssi/src/silc/core/client_ops.c.
3394 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3397 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3398 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3400 * Removed channel key rekey task deleting from the function
3401 silc_server_save_channel_key. Affected file silcd/server.c.
3402 Added explicit timeout task context instead that is used to
3403 delete the task if we are registering a new task before the
3404 new task has elapsed.
3406 * When channel key rekey occurs the client library now saves
3407 the old channel key for a short period of time (10 seconds) and
3408 is able to use it in case some is still sending channel
3409 messages encrypted with the old key after the rekey. Affected
3410 file lib/silcclient/[idlist.h|client_channel.c].
3412 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Added check to the silc_server_new_id_real to not accept
3415 new ID if it is the sender's own ID. Affected file is
3416 silcd/packet_receive.c.
3418 * Assure that we do not announce ourself or the one we've
3419 sending our announcements when we're router and are announcing
3420 servers to our primary router. Affected file silcd/server.c.
3422 * Fixed silc_server_command_identify_check_client to assemble
3423 correct WHOIS packet. It send corrupted WHOIS packet and
3424 caused problem with router to router connections. Affected
3425 file silcd/command.c.
3427 Fixed also silc_server_command_whois_check the same way
3428 as for the IDENTIFY command.
3430 * Added new SilcIDListStatus to the server in the SilcIDListData
3431 structure. The status now includes the current status of
3432 the entry (like registered, resolved etc.). Affected file
3433 silcd/idlist.[ch]. Defined a bunch of different status types
3434 as well. This replaced the old boolean registered field as well.
3436 Added resolve_cmd_ident field to the SilcClientEntry structure
3437 too so that if the entry is for example being resolved so
3438 another command may attach to the same pending command reply
3439 without requiring to resolve the same entry again. This concept
3440 should optimize the WHOIS and the IDENTIFY resolving under
3441 heavy load by taking away unnecessary resolving for entries
3442 that are being resolved already.
3444 Added support for adding multiple pending commands for one
3445 command idenfier. Affected file silcd/command[_reply].[ch].
3447 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3448 before deleting the data. Otherwise the hash table will have
3449 freed data in comparison functions. Affected file is
3450 silcd/command_reply.c.
3452 * Fixed silc_idlist_replace_client_id to add the new entry to
3453 the cache with NULL nickname. Otherwise there will be invalid
3454 memory as the nickname after the nickname is freed. Affected
3455 file silcd/packet_receive.c.
3457 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3458 saved into wrong slots because the previous number of entries
3459 was not taken into account. Affected file silcd/idlist.c.
3460 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3462 * If we are router and we receive JOIN notify to a channel that
3463 does not have any users then notified client is marked as the
3464 channel founder, as it is it. The affected file is
3465 silcd/packet_receive.c
3467 * Added to the extended hash table API's table_del_*ext functions
3468 the destructor as argument too, so that the caller can decide
3469 which destructor to use or whether to use destructor at all.
3470 Affected file lib/silcutil/silchashtable.[ch].
3472 * Fixed ID Cache purging. It actually deleted the entries from
3473 the hash table after the data was freed. The hash table ended
3474 up comparing freed memory. The affected file is
3475 lib/silccore/silcidcache.c.
3477 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3479 * Fixed Irssi SILC client's KILL command's HELP syntax.
3481 * The USERS command now resolves the detailed user information
3482 if the userinfo field is missing. Affected file is
3483 lib/silcclient/command_reply.c.
3485 * Do not print error in silc_file_read if the read file does
3486 not exist. Just silently return NULL. Affected file is
3487 lib/silcutil/silcutil.c.
3489 * Fixed the silc_log_output to not wine about NULL filename
3490 and to not create some bogus " " filename. Affected file is
3491 lib/silcutil/silclog.c.
3493 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Fixed various printing bugs on the user interface in the
3496 Irssi SILC Client. Minor changes that were forgotten from
3499 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Fixed the configure.in.pre and the compilation and distribution
3502 environment to support the new autoconf 2.52. That version is
3503 now required to compile the CVS trunk.
3505 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3508 to generally parse user@fqdn format strings. Affected file
3509 lib/silcutil/silcutil.c.
3511 * Added nickname_format and nickname_force_format fields to the
3512 SilcClientParams structure. The first one defines the format
3513 for the nicknames that the library will enforce if the receives
3514 multiple same nicknames. The second one is boolean value and
3515 can be used to force the library to always enforce the format
3516 to the nicknames regardles whether there are multiple nicknames
3517 or not. This configurable formatting was employed to flexibly
3518 support accessing multiple nicknames from the user interface.
3519 The userinterface can now set the nicknames to what ever format
3520 they prefer. Affected file lib/silcclient/silcapi.h.
3522 Added function silc_client_nickname_format to the file
3523 lib/silcclient/idlist.c. It performs the nickname formatting.
3525 Added new field `hostname´ to the SilcClientEntry context.
3526 It holds the hostname of the client. Affected file is
3527 lib/silcclient/idlist.h.
3529 * Irssi SILC Client sets the nicknames in nick@hostn format.
3530 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3531 irssi/src/silc/core/silc-core.c.
3533 The WHOIS printing now also shows both the real nickname and
3534 the formatted nickname so that user knows how to access the
3535 user if there are multiple same nicknames cached. Affected
3536 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3537 printing formatting too to take the hostname now as a separate
3538 argument. The Affected file is
3539 irssi/src/fe-common/silc/modules-formats.[ch].
3541 * Changed the silc_client_get_clients_local to accept the formatted
3542 nickname as argument. It accepts the real nickname too but the
3543 formatted nickname can be used to find the true entry from
3544 multiple entries. Affected file lib/silcclient/silcapi.h and
3545 lib/silcclient/idlist.c.
3547 * Added nickname_format_parse field to the SilcClientParams.
3548 It is a callback function provided by the application to parse
3549 the nickname out of the formatted nickname string. The library
3550 calls it to get the nickname from the formatted string. Since
3551 the application generally knows better the format of the nickname
3552 string it parses it instead of the library, even though library
3553 encodes the formatted string. If the callback function is not
3554 provided then the library will use the string as is. The
3555 affected file is lib/silcclient/silcapi.h.
3557 * All the nickname strings passed to the client library in
3558 commands are now expected to be formatted nickname strings.
3559 If the command does not support the formatted nickname string
3560 it will assume that the sent string is the actual nickname.
3561 Affected file lib/silcclient/command.c.
3563 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Added public key authentication support to OPER and SILCOPER
3566 commands in the client library. Affected file is
3567 lib/silcclient/command.c.
3569 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Changed the get_auth_methdod client operation to be asynchronous.
3572 It can be async if the application resolves the authentication
3573 method from the server during the negotiation. Added new
3574 SilcGetAuthMeth completion callback that the application will
3575 call after resolving the authentication method.
3577 Added function silc_client_request_authentication_method that
3578 the application can use to resolve the authentication method
3579 from the server. Added also SilcConnectionAuthRequest callback
3580 that the library will call after the server has replied. The
3581 application can call this function if it does not know the
3582 current authentication method.
3584 Affected files are lib/silcclient/client.c and
3585 lib/silcclient/silcapi.h.
3587 * The Irssi SILC client now automatically resolves the authentication
3588 method incase any configuration information is not present (and
3589 currently there never is). The affected file is
3590 irssi/src/silc/core/client_ops.c.
3592 * Fixed public key authentication from the client library.
3593 Affected file lib/silcclient/protocol.c. Changed also the
3594 protocol specification about the public key authentication in
3595 the connection authentication protocol. The actual data to be
3596 signed is now computed with a hash function before signing.
3598 * Fixed the public key authentication from the server as well.
3599 Affected file silcd/protocol.c.
3601 * Removed the mlock()'s from the memory allocation routines.
3602 Affected file lib/silcutil/silcmemory.c. The ./configure does
3603 not check anymore for the mlock(). Affected file is
3606 * Fixed USERS command in server to allow the execution of the
3607 command for private and secret channels if the client sending
3608 the command is on the channel. Affected file silcd/command.c.
3610 * Fixed silc_client_get_clients_local to return the clients
3611 count correctly. It could return wrong value. Affected file
3612 lib/silcclient/idlist.c.
3614 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3617 types. The assembler optimizations seemed not to like 64-bit
3618 data types. The assmebler optimizations thus are now enabled
3619 also for BSD systems as opposed to only enable them for Linux.
3621 * Do not check for threads at all on BSD systems. Affected
3622 file configure.in.pre.
3624 * Removed -n and -h options from the Irssi SILC Client since
3625 they are not used in silc.
3627 * Fixed the prime generation to assure that the first digit
3628 of the generated random number is not zero since our conversion
3629 routines does not like number strings that starts with zero
3630 digit. If zero digit is seen the random number is regenerated.
3631 This caused some corrupted RSA keys when the zero first digit
3632 was met. Affected file lib/silcmath/silcprimegen.c.
3634 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3636 * Fixed WIN32 configuration in the ./configure script.
3637 Fixed to include xti.h on environments that has it.
3638 Patches by Carsten Ilchmann and andrew.
3640 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3642 * Changed the silc_id_create_client_id to be collision
3643 resistant. It is now assured that there cannot be created
3644 two same client ID's. I suspect that some weird bugs in
3645 the server were actually caused by duplicate Client IDs.
3646 Affected file silcd/serverid.[ch]. A router receiving
3647 new ID now also assures and informs the sending server
3648 if the ID caused collision.
3650 * Changed the silc_id_create_channel_id to also assure that
3651 there are no collisions.
3653 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Statement about ignoring the Mutual Authentication flag when
3656 performing rekey with PFS was a bit misleading. It is ignored
3657 if it was set in the initial negotiation, it cannot be even
3658 set in the rekey. Fixed in the ke-auth draft. Started the
3659 new versions of the protocol drafts in the doc/.
3661 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3663 * Fixed a bug in silc_client_command_identify_save when saving
3664 new channel information. The channel name was no duplicated
3665 and caused crash on exit. Affected file is
3666 lib/silcclient/command_reply.c.
3668 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3670 * Fixed the getkey command handling in the server. Send just
3671 empty OK reply to the sender if the key could not be fetched
3672 (but everything else was ok, like the key just was not available).
3673 Changed the public key parameter to optional in the protocol
3674 specs so that empty OK reply can be sent. Affected file
3677 Added a message to Irssi SILC client to tell to user if the
3678 server did not return a public key.
3680 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3682 * Fixed a channel key regeneration bug. It registered new
3683 timeout tasks exponentially until all system resources were
3684 used. Affected file silcd/server.c.
3686 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Added the SILC Document generator to the scripts/silcdoc.
3689 It can be used to generate the Toolkit Reference Manual out
3690 of the source tree. Internally it will also use the RoboDoc
3691 generator now imported in util/robodoc.
3693 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Added couple of return's in rekey protocol if error orccurred
3696 during the protocol. The execution must be terminated.
3697 Affected file silcd/protocol.c. Also, terminate the protocol
3698 always with timeout.
3700 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * The client's Client ID was created initally from the wrong
3703 nickname (it could have been in format nick@host) in the
3704 silc_server_new_client. Affected file silcd/packet_receive.c
3706 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Added some SILC_LOG_ERROR's to various error conditions
3709 if client could not be added to ID cache. Affected files
3710 silcd/packet_receive.c and silcd/server.c.
3712 * When client's sock->user_data is freed, NULL also the
3713 client->router and client->connection pointers. Added check
3714 for these pointers being NULL to various places around the
3715 code. Affected file silcd/server.c.
3717 * Added client->data.registered == TRUE checks to various
3718 places around the code to assure that unregistered client's
3719 are not handled when it is not allowed. Affected file
3722 * Added `bool registered' fields to all
3723 silc_idlist_[server|client]_get_* routines to indicate whether
3724 the fetched client needs to be registered or not. Affected
3725 file silcd/idlist.[ch].
3727 * Add your own entry as registered to the ID cache in the
3728 server. Affected file server.c.
3730 * Fixed a bug in silc_server_new_server. The SilcServer was
3731 set as the new server's context instead of SilcServerEntry.
3732 This naturally caused some weird bugs.
3734 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Do not delete the channel rekey task when adding it
3737 for in silc_server_create_channel_key.
3739 * Changed the silc_server_create_channel_key to return
3740 TRUE or FALSE to indicate the success of the channel key
3743 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Fixed MSVC++ project files and added missing files to
3746 Makefiles under win32/.
3748 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Do not add TCP_NODELAY flag if the operating system
3751 does not have it defined. Affected files are
3752 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3754 * Fixed buffer overflow from Irssi SILC Client. Affected
3755 file irssi/src/fe-common/core/themes.c.
3757 * Fixed double free in client library in the file
3758 lib/silcclient/client.c when disconnecting from server.
3760 * Applied double free patch from cras to Irssi SILC client.
3761 Affected files irssi/src/core/[modules/expandos].c
3763 * Fixed the disconnection handling to Irssi SILC Client.
3764 The application must call silc_client_close_connection
3765 in ops->connect client operation in case of failure of
3766 the connection. Affected file is
3767 irssi/src/silc/core/client_ops.c.
3769 * Do not set sock->protocol to NULL in the function
3770 silc_client_close_connection after executing the protocol's
3771 final callback since the sock might not be valid anymore.
3772 Affected file lib/silcclient/client.c.
3774 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3776 * Do not enable SILC_THREADS if the linking with libpthread
3777 did not happen. Affected file configure.in.pre.
3779 * Added notion to protocol specification that server must
3780 verify the sent authentication payload with CMODE when
3781 setting the channel founder key. Implemented it to the
3782 server. Affected file silcd/command.c.
3784 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Added _EXTRA_DIST SILC distribution variable to the
3787 distributions file. It is used to conditionally add extra
3788 files or directories to the specific distribution. Affected
3789 files ./prepare, Makefile.am.pre and distributions.
3791 Removed the `_' from the start of the distribution names.
3794 * Added README.WIN32 for instructions to compile the Toolkit
3797 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Fixed a double free in disconnection in the server. Affected
3800 file is silcd/server.c.
3802 * Fixed the lib/silcske/groups.c to work now also with GMP
3803 MP library. The string conversion did not work when using
3804 specific base and the base is indicated in the string as well.
3806 * Created win32/ directory which now includes MSVC++ specific
3807 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3808 It will appear only in the toolkit distribution
3810 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Changed the key material distribution function in case when
3813 the hash output is too short. The data is now concatenated
3814 a bit differently than it used to. Made the change to the
3815 SKE protocol specification.
3817 * Added better GMP detection to configure.in.pre. A patch
3820 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * Fixed a minor bug in SKE that might cause some problem on
3823 some platforms. Affected file lib/silcske/silcske.c.
3825 * Added the cookie checking for initiator in the SKE. It checks
3826 that the responder returns the sent cookie unmodified. The
3827 affected file is lib/silcske/silcske.c. Added new SKE
3828 error type INVALID_COOKIE that can be sent during the
3829 negotiation. Fixed some memory leaks as well.
3831 * Added the "invalid cookie" error message to Irssi SILC client's
3834 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3836 * Added `task_max' field to the SilcClientParams to indicate
3837 the maximum tasks the scheduler can handle. If set to zero,
3838 default values are used. Affected file lib/silcclient/silcapi.h.
3840 * Fixed memory leaks in silc_client_close_connection. Affected
3841 file lib/silcclient/client.c.
3843 * Added silc_client_del_client_entry to client library to free
3844 all memory of given client entry. Affected file is
3845 lib/silcclient/idlist.[ch].
3847 * Added new functions silc_client_del_channel and
3848 silc_client_del_server to delete channel and server entries.
3849 Affected file lib/silcclient/[silcapi.h/idlist.c].
3851 * Removed silc_client_del_client_by_id from silcapi.h.
3853 * Fixed the INFO command to return the server's own info
3854 correctly when querying by Server ID. Affected file is
3857 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3859 * Removed the non-blocking settings in WIN32 code in the
3860 silc_sock_[read/write] and added SleepEx instead. Affected
3861 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3862 of input data is now checked with FIONREAD and ioctlsocket.
3864 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Call silc_schedule_task_del_by_context in the
3867 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3868 Affected file lib/silccore/silcprotocol.c.
3870 * Call silc_protocol_cancel for active protocols in the
3871 silc_server_close_connection if the funtion
3872 silc_server_free_sock_user_data has not been called.
3873 Affected file silcd/server.c.
3875 * Generic tasks cannot be deleted using the del_by_fd
3876 task deleting function since generic tasks does not match
3877 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3879 * Added a notion to SILCOPER help file that the SILCOPER works
3880 only on router server, not on normal server.
3882 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Added for WIN32 support for the new scheduler as well.
3885 Affected file lib/silcutil/win32/silcwin32schedule.c.
3887 * Fixed the SHA1 implementation to work on various platforms.
3889 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3892 API. It is part of the scheduler now. Everything else is
3893 as previously but some functions has changed their names.
3894 Checkout the lib/silcutil/silcschedule.h for the interface.
3895 Updated all applications to use the new interface. Affected
3896 files are lib/silcutil/silcschedule.[ch].
3898 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Found a bug in the SKE implementation. The HASH value,
3901 specified by the protocol, was not computed correctly. The
3902 public key of the responder was not added to the computation
3903 even though it is mandatory. Affected file lib/silcske/silcske.c.
3904 This unfortunately causes incompatibilities with older
3905 clients and servers.
3907 * Added WIN32 specific network init and uninit functions:
3908 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3909 the Winsock2. Affected file lib/silcutil/silcnet.h and
3910 lib/silcutil/win32/silcwin32net.c.
3912 * Set the socket always to nonblocking mode on WIN32 after
3913 reading data or writing data. Affected file is
3914 lib/silcutil/win32/silcwin32sockconn.c.
3916 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3918 * Fixed various compilation problems under WIN32. Affected
3919 files lib/silcutil/win32/silcwin32thread.c and
3920 lib/silcutil/win32/silcwin32schedule.c.
3922 * Removed all _internal.h #includes from public header
3923 files. Internal headers must never be included from
3926 Removed also the lib/silcske/payload_internal.h file.
3928 * All include files that may be needed (public and some others
3929 included by the public headers) by application developers are
3930 now copied to the ./includes directory. It does not copy any
3931 internal headers. Affected file Makefile.defines.pre and all
3932 Makefile.am's under lib/ and subdirs.
3934 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Do not change the ~/.silc directory's permissions automatically.
3937 Affected file irssi/src/silc/core/clientutil.c.
3939 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Do not cancel the protocol in silc_server_close_connection
3942 it might cause recursion. Now cancelled in the function
3943 silc_server_free_sock_user_data. Affected file silcd/server.c.
3945 * Fixed the silc_server_remove_clients_by_server to regenerate
3946 the channel keys correctly finally. Added also new function
3947 silc_server_remove_clients_channels to actually do it.
3948 Affected file silcd/server.c.
3950 * Fixed the silc_server_new_channel to not crash by giving
3951 wrong router to the new channel. Affected file is
3952 silcd/packet_receive.c.
3954 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3956 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3957 which is given as argument to the silc_client_alloc now.
3958 It can be used to configure the client and set various parameters
3959 that affect the function of the client.
3961 * The USERS command in server did not check whether the channel
3962 is private or secret. Affected file silcd/command.c.
3964 * Added new argument to the USERS command in protocol specification.
3965 The USERS command now can take the channel name as argument
3966 as well. Added support for this in client and server and
3967 updated the protocol specs.
3969 * Completed the GETKEY command in client. It can be now used
3970 to fetch also servers public key not only some clients.
3971 Affected files lib/silcclient/command[_reply].c.
3973 * Added silc_client_get_server to return server entry by the
3974 server name. Affected files lib/silcclient/silcapi.h and
3977 * Redefined the IDENTIFY command in protocol specification to be
3978 more generic. It now can be used to query information about
3979 any entity in the SILC Network, including clients, servers and
3980 channels. The query may be based either the entity's name
3981 or the ID. Added support for this in both client and server.
3983 Affected files silcd/command.c and lib/silcclient/command.c
3984 and command_reply.c.
3986 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3987 the _from_client and _from_server functions. Affected file
3990 * Added silc_client_get_channel_by_id_resolve to the file
3991 lib/silcclient/silcapi.h to resolve channel information by
3992 its ID. Added also silc_client_get_channel_by_id that
3993 does not resolve it from the server.
3995 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Added SilcServerEntry context into the client library
3998 to represent one server. The INFO command now allocates
3999 these to save the resolved server info. For now on the
4000 client library will also keep information about servers,
4001 connected and resolved with INFO.
4003 The INFO command now allocates the SilcServerEntry context
4004 and saves the server info there. The COMMAND_REPLY in
4005 the INFO now returns the parameters to application in
4006 same order as defined in the protocol specification.
4008 The entries are cached in the client->server_cache.
4010 * The INFO command is now issued after received the Client ID
4011 from the server. Affected file lib/silcclient/client.c.
4013 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4014 to the application as the mode changer might be server.
4015 It is guaranteed that NULL is not returned anymore to the
4016 application. Affected file lib/silcclient/client_notify.c.
4018 The ID Type is now also passed to the application so that
4019 it can check whether the returned entry is SilcClientEntry
4022 Added new function silc_client_get_server_by_id to return
4023 the server entry by ID. Affected files are the
4024 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4026 * Do not create the channel in the Irssi SILC Client when issuing
4027 the JOIN command but when received the sucessful JOIN command
4028 reply. Otherwise the channel might get created even though we
4029 could not join it. The Affected file is
4030 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4032 * Fixed a channel joining bug in router. The router must also
4033 check the channel modes, invite and ban lists etc. when serving
4034 the JOIN command sent by normal server. Affected file is
4035 silcd/command.c. The router now resolves the client's
4036 information from the server who sent the JOIN command if it
4037 does not know it, and processes the JOIN command only after
4040 * Changed the SilcCommandCb to take new argument; void *context2.
4041 Affected file lib/silccore/silccommand.h
4043 The second argument in the command callbacks in the server now
4044 includes the SilcServerCommandReplyContext if the command was
4045 called as pending command callback from the command reply.
4046 Otherwise it is NULL. When called as pending the status of the
4047 command reply will be checked and if it was erronous the
4048 error will be sent to the original sender of the command.
4049 This way the client always receives the error messages even
4050 though the server was actually the one who received the error
4051 when it resent the command to router, for example. Affected
4052 files silcd/command[_reply].[ch].
4054 * Fixed sending WHOWAS command's error message to client if
4055 the requested client could not be found. It was missing.
4058 * Changed the CMODE and CUMODE commands reply arguments in the
4059 protocol specification. The Channel ID is now sent in both
4060 of the commands to identify the channel. Implemented this
4061 new feature to the client and server. Affected files
4062 lib/silcclient/command_reply.c and silcd/command.c.
4064 * Made better checks for invite and ban lists in the JOIN
4065 command in server. Affected file silcd/command.c.
4067 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4069 * The server now performs the incoming host IP/DNS lookup
4070 using the silc_socket_host_lookup and thus does not block
4071 the server anymore. Affected file silcd/server.c.
4073 * Completed the multi-thread support for SILC Scheduler in
4074 the lib/silcutil/silcschedule.c.
4076 * Fixed the configure.in.pre to detect the pthread correctly
4079 * Fixed a deadlock in silc_task_queue_wakeup in the file
4080 lib/silcutil/silctask.c.
4082 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Added new function silc_schedule_wakeup that is used in
4085 multi-threaded environment to wakeup the main thread's
4086 schduler. It needs to be used when a thread adds a new task
4087 or removes a task from task queues. After waking up, the
4088 scheduler will detect the task queue changes. If threads
4089 support is not compiled in this function has no effect.
4090 Implemented the wakeup mechanism to both Unix and WIN32
4091 systems. Affected files are lib/silcutil/silcschedule.[ch],
4092 lib/silcutil/unix/silcunixschedule.c and the
4093 lib/silcutil/win32/silcwin32schedule.c.
4095 * Added new function silc_task_queue_wakeup to wakeup the
4096 scheduler by the specified task queue. Affected file
4097 lib/silcutil/silctask.[ch].
4099 * The silc_socket_host_lookup_start now wakes up the scheduler
4100 after adding the timeout task. Affected file is
4101 lib/silcutil/silcsockconn.c.
4103 * The silc_socket_host_lookup is synchronous now if the threads
4104 support is not compiled in. However, the callback is still
4105 called asyncronously through the scheduler, anyway. Affected
4106 file lib/silcutil/silcsockconn.c.
4108 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4110 * Added new function silc_socket_host_lookup to perform
4111 asynchronous IP and FQDN lookups for the socket connection.
4112 Affected files lib/silcutil/silcsockconn.[ch].
4114 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4116 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4117 that may or may not compile the mutex support in.
4119 Changed the silc_mutex_alloc interface. It allocates the
4120 mutex now to the sent pointer and returns TRUE or FALSE.
4122 Affected file lib/silcutil/silcmutex.h.
4124 * Wrote the SILC Task Queue interface to support multi-threads.
4125 Affected file lib/silcutil/silctask.[ch].
4127 * Wrote the SILC Scheduler to support multi-threads. Affected
4128 file lib/silcutil/silcschedule.c.
4130 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4133 in lib/silcutil/win32/.
4135 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Defined SILC Mutex API and SILC Thread API and implemented
4138 them for Unix. Affected files are
4139 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4140 lib/silcutil/unix/silcunixmutex.c and
4141 lib/silcutil/unix/silcunixthread.c.
4143 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4145 * Fixed the silc_server_remove_clients_by_server's channel
4146 key re-generation. The hash table handling was incorrect
4147 and would not work with many channels. Affected file is
4150 * Fixed some memory leaks around the server code.
4152 * Rewrote the silc_server_get_users_on_channel to support IPv6
4153 based Client ID's. Affected file silcd/server.c.
4155 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4156 specification. However, a separate document must be written
4157 to define the detailed signing procedure and the payload
4158 associated with the flag. Defined the flag to the
4159 lib/silccore/silcchannel.h as well.
4161 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Changed the dynamic tables to static size tables in the
4164 lib/silccrypt/silchmac.c.
4166 * Removed GCC dependencies from the code. A patch by cras.
4168 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Do not show the error "Error receiving packet bla bla"
4171 in server if it really was not an error (-2 means that reading
4172 is pending). Affected file silcd/server.c.
4174 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Fixed a possible crash in silc_server_remove_clients_by_server
4177 in silcd/server.c. Fixed there also some memory leaks.
4179 * Fixed the silc_idlist_replace_client_id. It could replace
4180 wrong key in the hash table. Affected file silcd/idlist.c.
4182 * Do not check whether there are global users on the channel
4183 if the channel->global_users is FALSE. Affected functions
4184 silc_server_remove_from_one_channel and
4185 silc_server_remove_from_channels in silcd/server.c. Also,
4186 do not check if the removed client is local as we can be
4187 sure that global client was not removed from the channel
4188 and checking for global users is not needed.
4190 * The silc_server_remove_clients_by_server now re-generates
4191 the channel keys correctly for those channels that had
4192 clients removed from them. Affected file silcd/server.c.
4194 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4196 * Found the reason of random crashes in the server. We weren't
4197 ignoring the SIGPIPE signal (which can be sent in write())
4198 and it crashed the server. Affected file silcd/silcd.c.
4200 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4202 * Assure that sock->user_data is not NULL in the function
4203 silc_server_packet_send in silcd/packet_send.c.
4205 * Disconnect the remote connection if it could not be added
4206 to any ID lists in the server. The affected file is
4209 * Check in silc_server_packet_send[_real/dest] that the
4210 socket is not disconnecting and ignore the data if it is.
4211 Affected file silcd/packet_send.c.
4213 * Define inline to __inline on native WIN32 compilation.
4214 Affected file includes/silcwin32.h.
4216 * Added some explicit type casts for inline code since MSVC
4217 require them. Affected files lib/silcutil/silcbuffer.h,
4218 lib/trq/silcdlist.h and lib/trq/silclist.h.
4220 * Print warning in log files from now on if the packet
4221 decryption fails. Affected file silcd/server.c.
4223 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4225 * Changed the `say' client operation's interface to accept
4226 new `type' argument to indicate the type of the message sent
4227 by the library. The application may filter the library's
4228 messages according the type. The affected file is the
4229 lib/silcclient/silcapi.h.
4231 * Added two new functions to lib/silcclient/silcapi.h:
4232 silc_client_del_client and silc_client_del_client_by_id.
4233 Affected file lib/silcclient/idlist.c.
4235 * Moved the clientincludes.h from includes/ to silc/ and
4236 serverincludes.h from includes/ to silcd/.
4238 * The modes for the CMODE and CUMODE are now passed as
4239 uint32 for application with COMMAND_REPLY. The affected
4240 file is lib/silcclient/command_reply.c.
4242 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4244 * /WHOIS without arguments shows client's own information.
4245 Affected file lib/silcclient/command.c.
4247 * Changed PING to not accept any arguments. The specs
4248 says that client can ping only the connected server so
4249 requiring an argument is not needed. Affected file is
4250 lib/silcclient/command.c.
4252 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Fixed a fatal bug in private message sending and reception
4255 encryption and decryption when using private message keys.
4256 The implementation was incorrect and did not follow the
4257 specification. It causd that some of the message were
4258 lost since it did not use the sending and receiving keys
4259 as the protocol suggests. This has been fixed and will cause
4260 incompatibilities with older clients when sending private
4261 message encrypted with private message keys. Affected files
4262 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4263 and various other in Irssi SILC Client.
4265 Added `responder' boolean argument to the functions
4266 silc_client_add_private_message_key[_ske] to indicate when
4267 the key is added as responder or initiator of the key
4270 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4272 * Removed the silc_ske_check_version function and created
4273 a SilcSKECheckVersion callback. Added also a function
4274 silc_ske_set_callbacks that is now used to set all SKE
4275 callbacks. The callback functions are not given to
4276 the SKE functions anymore, but this function is used to
4279 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4281 * Added `silc_version' argument to the silc_client_alloc
4282 to define the version of the application for the library.
4283 The library will use the version string to compare it
4284 against the remote host's (usually a server) version
4285 string. Affected file lib/silcclient/silcapi.h
4287 * Added the KE protocol context to Key Agreement context
4288 in client library so that we can abort the SKE if it
4289 is in process when we get timeout. Affected file is
4290 lib/silcclient/client_keyagr.c.
4292 * Do not resolve the client ID forever if it returns in the
4293 first time that such client does not exist. This was done
4294 for example with private message. Affected file is
4295 lib/silcclient/client_prvmsg.c.
4297 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4299 * Do not add regex.h for WIN32. The affected file
4300 includes/silcincludes.h.
4302 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4303 not work yet 100%. It generates the DLL's automatically
4304 when compiling with --with-win32 under cygwin.
4306 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4308 * lib/contrib/regex.c is not compiled on WIN32.
4310 * Added silc_net_get_socket_opt function to the
4311 lib/silcutil/silcnet.h.
4313 * Added includes/silcwin32.h for WIN32 specific includes
4316 * Do not use ptime structure or any of the posix process
4317 functions on WIN32 in lib/silccrypt/silrng.c.
4319 * Added silc_gettimeofday to provide generic function
4320 for struct timeval on all platforms. Added the function
4321 to lib/silcutil/silcutil.h.
4323 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4325 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4326 library as they clearly belong there. As a plus side we
4327 can make the actual socket connection routines platform
4330 Added also new generic function silc_socket_read and
4331 silc_socket_write (that used to be silc_packet_[read/write].
4332 The implementation of these are platform specific.
4334 * Added WIN32 specific routines of silc_socket_[read/write]
4335 to lib/silcutil/win32/silcwin32sockconn.c.
4337 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Added preliminary support for native WIN32 compilation under
4340 cygwin (using the -mno-cygwin option for GCC) to the
4341 ./configure.in.pre. The --with-win32 now prepares the
4342 compilation for native WIN32.
4344 * Rewrote the SILC Scheduler interface in the file
4345 lib/silcutil/silcschedule.h. The scheduler is now context
4346 based and does not have anymore any global static scheduler.
4347 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4348 and created lib/silcutil/win32 directory for WIN32 based
4351 * Added Unix specific network routines to the
4352 lib/silcutil/unix/silcunixnet.c and the old
4353 lib/silcutil/silcnet.c includes now only generic routines.
4355 Added WIN32 specific network routines to the
4356 lib/silcutil/win32/silcwin32net.c.
4358 * Added Unix specific utility functions from the
4359 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4361 * Added WIN32 SILC Scheduler to the file
4362 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4365 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4367 * Do not handle JOIN notify in the server if the target client
4368 is not registered (idata->registered == FALSE). The affected
4369 file is silcd/packet_receive.c.
4371 * Update the nickrec->founder in event_cumode in the Irssi SILC
4372 client. Affected file irssi/src/silc/core/silc-channels.c.
4374 * Fixed the CUMODE_CHANGE notify handling in the server when
4375 server and router are announcing their clients on channels.
4376 Now the mode changes are saved and notified correctly. The
4377 affected file is /silcd/packet_receive.c.
4379 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4380 They really did not replace the cache entry in the ID Cache.
4381 Now they do that. Affected file silcd/idlist.c.
4383 * Fixed the KICK notify handling in the Irssi SILC client to
4384 update the channel records so that the kicked client does not
4385 appear to be on the channel. The affected file is
4386 irssi/src/silc/core/silc-channels.c.
4388 * Always update the conn->current_channel when executing command
4389 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4391 * Fixed the KILL notify handling in Irssi SILC client to remove
4392 the killed client on all channels.
4394 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Fixed the silc_parse_command_line to remove extra spaces
4397 from the start and end of the arguments. Affected file is
4398 lib/silcutil/silcutil.c.
4400 * Cancel and free any active protocol in the function
4401 silc_server_close_connection. Affected file silcd/server.c.
4403 * Cancel and free any active protocol in the function
4404 silc_client_close_connction. Affected file is
4405 lib/silcclient/client.c.
4407 * Do not execute the KILL command for clients that are in
4408 history (ie. they are not in the network). Affected file is
4411 * Fixed KILL notify handling, client does not crash anymore.
4412 Affected file irssi/src/silc/core/silc-channels.c.
4414 * Reduced the default packet buffer size from 2048 to 1024 in
4415 lib/silccore/silcpacket.c.
4417 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4418 counter to the SKE context that is incresed when the SKE library
4419 performs async operation outside the library. If the outside
4420 process frees the SKE context and FREED status will be set
4421 and the library will detect after the sync operation that the
4422 libary is freed. The affected files are
4423 lib/silcske/silcske[_status].[ch].
4425 * Resolve the client entry information in the function
4426 silc_client_channel_message to assure that NULL pointer is not
4427 passed as client entry to the application. */
4429 * Fixed the task timeout calculation to assure that there is
4430 never negative timeouts. The affected file is
4431 lib/silcutil/silcschedule.c.
4433 * Fixed the channel user mode notification sending in server.
4434 It was sent point-to-point to the router (or to server by router)
4435 but it needs to be destined to a channel. The routines now
4436 supports sending the channel user mode notifys to the channels
4437 when announcing clients and channels. Affected files are
4438 silcd/server.c and silcd/packet_receive.c.
4440 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4441 It did not actually replace the old channel entry in the cache.
4442 Affected file lib/silcclient/client_notify.c.
4444 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Fixed a possible crash in silc_packet_send_prepare. It now
4447 assures always that there is enough space in the buffer and
4448 at the tail area of the buffer (for MAC).
4450 Fixed the inbound buffer reallocation in silc_packet_read.
4451 It was old code and did not handle the reallocation correctly.
4454 The affected file is lib/silccore/silcpacket.c.
4456 * Fixed buffer overflow in silc_parse_nickname in the file
4457 lib/silcutil/silcutil.c.
4459 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * make install generates new server keys only if there is not
4464 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4467 Added check that if the NOREPLY is set then we will not send
4468 the away message. This avoids infinite loop of away messages
4469 if both clients are away. The affected file is
4470 lib/silcclient/client_prvmsg.c.
4472 * Fixed client crash if /NICK was given without arguments.
4473 Affected file lib/silcclient/command.c.
4475 * Server does not send the invite list in INVITE command back
4476 to the client if the list was not altered. Added this notion
4477 to the protocol spec as well. Affected file silcd/command.c.
4479 Fixed possible crash in INVITE command by checking the
4480 value of silc_server_get_client_route command.
4482 * Fixed the INVITE notify type handling. The arguments are now
4483 taken in correct order and client does not crash. The affected
4484 file is irssi/src/silc/core/silc-channels.c.
4486 Removed the "Inviting xxx to channel" message from the
4487 client library away and let the application handle it.
4488 Affected file lib/silcclient/command.c. Added that message
4489 to Irssi SILC client's message formats.
4491 * Fixed CMODE command crash in client. It now checks the
4492 amount of arguments correctly and does not crash. The affected
4493 file is lib/silcclient/command.c.
4495 * Do not create new channel automatically in silc_channels_join
4496 but check whether the channel by that name already exists.
4497 Affected file irssi/silc/core/silc-channels.c.
4499 * Do not send the SERVER_SIGNOFF to router if the disconnected
4500 entity was the router. Affected file silcd/server.c.
4502 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4503 SILC client as it was missing from there.
4505 Added the handling of the KICK notify to the Irssi SILC client
4506 as it was missing. Added "you have been kicked" message to
4507 Irssi SILC client's message modules formats.
4509 Added the handing of the KILL notify to the Irssi SILC client
4510 as it was missing. Added the kill message module formats
4513 The affected file is irssi/src/silc/core/silc-channels.c.
4515 * The router did not save the channel mode the server announced.
4516 Affected file silcd/packet_receive.c.
4518 * Fixed a possible crash in INFO command in server. If the
4519 server did not provide the server info it crashed. Affected
4520 file silcd/command.c.
4522 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed the GETKEY command in the server to check also the
4525 global list. Otherwise the GETKEY would not work correctly
4526 in normal SILC server. Affected file silcd/command.c.
4528 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Fixed GETKEY crash, it crashed if the command did not succseed.
4532 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4535 is now real and not just an macro interface to GMP.
4537 Removed the entire GMP from the source tree and imported new
4538 NSS MPI library instead. Reason for removing GMP is that it is
4539 extremely large and compiles extremely slow. The NSS MPI
4540 is only a few files and compiles in less than 10 seconds.
4541 The speed is also about the same as GMP. The MPI is imported
4542 to lib/silcmath/mpi.
4544 If the system has GMP installed we will still use the GMP.
4545 If it is not then the NSS MPI will be compiled.
4547 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Merged a long nickname (127 characters long) crash bugfix from
4550 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4552 * Merged a freed memory reference bugfix from Irssi CVS tree.
4553 Affected file irssi/src/core/commands.c.
4555 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added the server's public key sving and verification to the
4558 server when performing the SKE. This was missing and the
4559 remote server's (or router's) public key was accepted without
4560 checking whether we have it previously or trust it at all.
4561 Affected file silcd/protocol.c.
4563 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Check in the silc_server_timeout_remote if protocol is active
4566 and make sure that the protocol's final callback is called so
4567 that all memory if freed. Affected file silcd/server.c.
4569 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * silc_server_whois_send_reply crashed the server if the nickname
4572 was 127 characters long. Affected file silcd/command.c.
4574 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Added sanity check to the silc_server_new_client. If the hostname
4577 is provided inside username then check that the provided hostname
4578 really is the same as the resolved one. If the hostname was not
4579 resolved then check it from the public key. Affected file is
4580 silcd/packet_receive.c.
4582 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4583 if the server disconnected us and the connection is not valid
4584 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4586 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4587 the library to the lib/silcutil/silcutil.[ch].
4589 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Close log file after open. Affected file
4592 lib/silcutil/silclog.c.
4594 * Check whether sock == NULL in silc_client_send_packet and return
4595 if it is. Affected file lib/silcclient/silcclient.c.
4597 * Check rec->entry == NULL in the Irssi SILC Client before
4598 sending the channel message. Affecte file is
4599 irssi/src/silc/core/silc-servers.c.
4601 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Merged a splitted window bugfix from Irssi CVS tree. The
4604 affected file is irssi/src/fe-text/textbuffer-view.c.
4606 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4607 It did not print nickname.
4609 * Improved the distributions system a bit.
4611 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4614 irssi/src/fe-text/gui-window.c.
4616 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4617 to in-active server. The affected file is
4618 irssi/src/silc/core/client_ops.c.
4620 * Resolve the client in USERS command reply if the entry does
4621 not have username resolved. The affected file is
4622 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4623 command to WHOIS command to really resolve stuff. The USERS
4624 is not used any more in any critical section so WHOIS can
4625 be used even though it might be slower than IDENTIFY.
4627 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4630 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Changed the protocol API a bit more consistent in the
4633 lib/silccore/silcprotocol.[ch].
4635 * Changed the following headers to ROBODoc format:
4637 lib/silccore/silcpayload.h
4638 lib/silccore/silcprotocol.h
4639 lib/silccore/silcsockconn.h
4641 All core library headers are now formatted.
4643 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Fixed a bug in Irssi SILC client; do not show that you are
4646 server/router operator if you really are not. Affected file is
4647 irssi/src/silc/core/client_ops.c.
4649 * Renamed silc_command_free_payload to silc_command_payload_free.
4650 Affected file lib/silccore/silccommand.h
4652 * Added silcmath.h to include the prototoypes of various routines
4653 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4656 * Changed the following headers to ROBODoc format:
4658 lib/silccore/silcchannel.h
4659 lib/silccore/silccommand.h
4660 lib/silccore/silcid.h
4661 lib/silccore/silcidcache.h
4662 lib/silccore/silcmode.h
4663 lib/silccore/silcnotify.h
4664 lib/silccore/silcpacket.h
4665 lib/silcmath/silcmath.h
4667 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added checking to the server code not to start the server if
4670 ciphers and stuff are not configured properly. Affected files
4671 silcd/serverconfig.[h] and silcd/server.c.
4673 * Changed the layout of the header files of the public interfaces
4674 in the SILC libraries. The new layout supports ROBODoc
4675 documentation tool (and some others) so that it is easy to create
4676 a library reference manual. All the other headers and source
4677 code must still follow the CodingStyle document. Also source
4678 code must not include these ROBODoc stuffs, only the headers.
4679 Furthermore, all public interface headers must now be named
4680 by using `silc' prefix, example: silcapi.h, silccipher.h.
4681 Some files were renamed due to this. All the other headers
4682 must not be used as public interfaces. I will update the
4683 CodingStyle document later. Changed following headers, so far:
4685 lib/silcclient/silcapi.h
4686 lib/silccore/silcauth.h
4687 lib/silccore/silcprivate.h
4688 lib/silccrypt/silcdh.h
4690 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Removed silc_client_packet_send_flush from the client library
4695 as it is not needed. Affected file lib/silcclient/client.[ch].
4697 * Added printing of message of unresolved authentication method
4698 to the Irssi SILC client. Added it to the module formats.
4699 Removed the same message from the client library.
4701 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added new distribution feature, DISTLABEL. Every distribution
4704 can define own preprocessor label that can be used in the
4705 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4706 file distributions, acconfig.h.pre and prepare.
4708 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Added Makefile.defines_int to include the actual definitions
4711 for Makefile.defines.in. Tested the new distribution system,
4712 created distributions and tested installation.
4714 * Added AWAY message printing to the Irssi SILC client. Added
4715 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4717 * Added SCONNECT command to call the SILC's CONNECT command.
4718 Cannot use CONNECT directly since Irssi uses that internally.
4719 Affected file irssi/src/silc/core/silc-servers.c.
4721 Added ACTION local command. It is same as ME command but takes
4722 the channel as mandatory argument.
4724 Rewrote some of the Irssi's help files to suite for SILC
4727 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Added Makefile.defines[.in] that should for now on be included
4730 in all Makefile.am file in the source tree. That file includes
4731 all common compilation definitions for SILC source tree.
4733 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Minor changes to the ./prepare script to change the package
4736 name according the distribution name to the configure.in.
4738 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Created new distribution system. Added file `distributions'
4741 that defines all the distributions that can be created out of
4742 the SILC source tree. The ./prepare script now reads that
4743 file to determine how to prepare the distributions. The
4744 first argument to the ./prepare is the name of the distribution
4745 and second is the version of the distribution. If given
4746 without arguments it creates the default (toolkit) distribution
4747 with the default version (defined in ./prepare).
4749 All Makefile.am files that are subject to the distributions
4750 are now named as Makefile.am.pre. These are ./Makefile.am
4751 and lib/Makefile.am. Others may be changed later.
4753 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added invite list, ban list, some key management and connection
4756 error message printing to module formats in the Irssi SILC client.
4758 * Added new silc_client_set_away_message to set the away message
4759 that is back to the person who sent private message. The
4760 affected file lib/silcclient/silcapi.h and the
4761 lib/silcclient/client_prvmsg.c.
4763 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Fixed the private message sending in the Irssi SILC client,
4766 added local command KEY to the Irssi SILC client.
4768 Added key management and key agreement message formats to the
4769 irssi/src/fe-common/silc/module-formats.[ch].
4771 Added USERS (alias WHO) printing, server/router operator
4772 indication and LIST command printing to the module formats.
4774 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Fixed channel joining notify handling, cumode notify handling
4777 from Irssi SILC client.
4779 * Added SILC specific module-formats to the Irssi SILC client so
4780 that SILC specific message hilighting, colors etc is possible.
4781 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4783 Added channel mode, channel user mode, actions, notices,
4784 whois and whowas printing to the the module-formats.c.
4786 * Fixed a bug in channel deletion in the server. The channel
4787 is not left to the cache even if the channel founder auth mode
4788 is set when there are no users anymore on the channel. Affected
4789 file silcd/server.c.
4791 * The silc_net_localhost now resolves the entire hostname including
4792 the domain name. Affected file lib/silcutil/silcnet.c.
4794 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Changed the ask_passphrase client operation to be ascynchronous.
4797 It has now a completion callback and a context that the
4798 application must call after it has got the passphrase from
4799 the user. Affected files lib/silcclient/silcapi.h,
4800 lib/silcclient/protocol.c, lib/silcclient/command.c and
4803 Added SilcAskPassphrase callback that the application calls
4804 to deliver the passphrase to the library.
4806 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4807 The public key verification and especially a certificate
4808 verification is asynchronous procedure.
4810 Added new SILC_SKE_STATUS_PENDING status to indicate the
4811 request is pending and a callback will be called to finalize
4814 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4815 indicate that remote end did not send its public key (or
4816 certificate), even though we require it. Added check for this
4817 condition in the SKE. This was a security bug, now fixed.
4819 Defined new SilcSKEVerifyCbCompletion callback that is called
4820 when the verification process is completed.
4822 The affected files lib/silcske/silcske_status.h and
4823 lib/silcske/silcske.[ch].
4825 * Changed the verify_public_key client operation to be async
4826 as well. Defined SilcVerifyPublicKey callback that is used to
4827 indicate the success of the public key verification process.
4829 Changed the server and client to use the new async client
4832 * Changed the Irssi SILC client's internal scheduler to be called
4833 twice as many times as it used to be. As a result the client
4834 should be a bit faster now. Affected file is
4835 irssi/src/silc/core/silc-core.c.
4837 * Added support to Irssi SILC client of asynchronous public key
4838 verification and passphrase inquiry. Affected file is
4839 irssi/src/silc/core/silc-core.c.
4841 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Do not say "You have left channel %s" in client library.
4844 Moved it to the application. Affected files are
4845 lib/silcclient/command.c and silc/client_ops.c.
4847 * Fixed silc_client_get_clients. Command context was not
4848 duplicated and was freed memory in the callback. Affected
4849 file lib/silcclient/idlist.c.
4851 * Do not say "you are now talking..." on JOIN command in the
4852 client library. The appliation must handle it.
4854 * Do not say ".. changed topic to" in command reply in the
4855 client libary. The application must handle it.
4857 * Fixed TOPIC command sending in the client library.
4859 * Fixed a memory leak in silc_client_command_free in the file
4860 lib/silcclient/command.c.
4862 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Imported a modified version of Irssi client to the source tree.
4865 The Irssi will be used to create a new client called
4866 Irssi SILC. Imported to irssi/.
4868 Added silc_core_init_finish function to the Irssi. Affected
4869 file irssi/configure.in.
4871 A lot changes in the Makefile.ams around the irssi tree.
4873 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Do not rehash if the new size is same as the old size of the
4876 hash table, in the silc_hash_table_rehash*. The affected file
4877 lib/silcutil/silchashtable.c.
4879 * Replaced hash_table_del_by_context calls from the server
4880 (when channel->user_list and client->channels) to the
4881 hash_table_del as it is sufficient and faster.
4883 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added silc_hash_table_list, silc_hash_table_get and the
4886 SilcHashTableList structure to provide an alternative way to
4887 traverse the hash table. The affected files are
4888 lib/silcutil/silchashtable.[ch].
4890 * Changed the server's idlist routines to use the hash table
4891 routines to optimize the code.
4893 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Replaced the client entry's `channel' list and channel entry's
4896 `user_list' list to hash tables for optimized lookup. Changed
4897 the code to use the hash table interface around the code.
4898 Affected file lib/silcd/idlist.[ch].
4900 * Added `auto_rehash' boolean argument to the function
4901 silc_hash_table_alloc to indicate whether the hash table should
4902 auto-rehash when it thinks is appropriate time. It will
4903 increase the hash table size if the there is twice as much
4904 entries in the table than the size of the table, and will
4905 decrease the size if there are twice as less entries than
4906 the size of the table.
4908 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4912 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * silc_idcache_purge_by_context deletes the entry now by context
4915 as it is supposed to do. Affected file lib/silccore/idcache.c.
4917 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4918 client is not anymore valid (WHOWAS givens the info) and not
4919 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4921 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Removed the `data' and `data_len' arguments from the ID Cache
4924 interfaces and added `name' argument. ID Cache does not handle
4925 anymore the binary data only a names associated with given ID.
4927 * When hashing a Client ID with silc_hash_id the entire ID is
4928 not hashed anymore, instead only the hash of the Client ID is
4929 hashed. This way we can access the Client ID from the cache
4930 with Client ID but with the hash of the ID (which is a hash of
4931 the nickname) as well without any difference in performance.
4933 Added also silc_idcache_find_by_id_one_ext to do one on one
4934 searching when we have the actual ID. Added also function
4935 silc_hash_client_id_compare. The affected files are
4936 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4938 * When hashing the name associated with a ID it is always done
4939 in lowercase. This way we can access the cache without worrying
4940 about case-sensitivity, even though, for example nicknames are
4943 * Fixed a bug in server with channel message sending. It put
4944 wrong ID type as destination ID. The affected file
4945 silcd/packet_send.c.
4947 * silc_idcache_del_by_context now deletes from all hash tables
4948 by context. Affected file lib/silccore/idcache.c.
4950 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Changed the client library to use the new ID Cache interface.
4953 Changes around the source tree.
4955 * Added silc_hash_table_rehash_ext to rehash with specific
4956 hash function. Affected file lib/silcutil/silchashtable.[ch].
4958 * Added silc_hash_string_compare to compare two strings in the
4959 hash table. Affected file lib/silcutil/silcutil.[ch].
4961 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added new function silc_idcache_del_by_context into the
4964 lib/silccore/idcache.[ch].
4966 * Changed the server's ID list routines to use the new ID Cache
4967 interface. Changes around the source tree.
4969 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added silc_hash_table_del[_by_context]_ext functions in to the
4972 lib/silcutil/silchashtable.[ch].
4974 Removed silc_hash_table_find_all* routines and added new
4975 silc_hash_table_find_foreach to replace them.
4977 Added silc_hash_table_replace_ext function as extended
4978 replacing function. Separated the simple hash table interface
4979 from the extended hash table interface in the file
4980 lib/silcutil/silchashtable.h.
4982 * Fixed minor bugs and changed it to use some of the new
4983 hash table functions in lib/silccore/idcache.c
4985 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Added new function silc_hash_table_find_all to return all keys
4988 in the hash table by the specified key. As the hash table is
4989 collision resistant it also makes it possible to have several
4990 duplicate keys in the hash table. This function may be used to
4991 find all of the keys from the hash.
4993 Added user_context arguments to the SilcHashFunction,
4994 SilcHashCompare and SilcHashDestructor to deliver user specified
4997 Added new fuctions silc_hash_table_find[_all]_ext to do
4998 extended lookup with specified hash and compare functions and
4999 specified user contexts.
5001 Added new function silc_hash_table_add_ext to add the key
5002 with specified hash function and user context.
5004 Added new function silc_hash_table_foreach to traverse all
5005 entrys in the hash table. Added SilcHashForeach callback
5008 Added new function silc_hash_table_del_by_context to delete
5009 the entry only if the context associated with the key matches.
5011 Affected files are lib/silcutil/silchashtable.[ch].
5013 * Removed silc_hash_[server/client/channel]_id and added just
5014 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5015 silc_hash_id_compare to compare two ID's using as the hash table
5016 comparison function. Added also silc_hash_data to hash
5017 binary data and silc_hash_data_compare to compare it.
5019 * Removed silc_idlist_find_client_by_hash as it is not needed
5020 anymore. Affected file silcd/idlist.[ch].
5022 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5023 to use internally the SilcHashTable. The new ID Cache is a lot
5024 faster than the old one. Some of the ID Cache interface was also
5025 rewritten and obsolete and stupid functions were removed.
5027 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Added entry_count field to the SilcHashTable to keep the number
5030 of the entries in the table. Implemented the function
5031 silc_hash_table_rehash. Added new function
5032 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5034 Fixed a minor bug in silc_hash_table_free.
5036 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5037 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5038 into the lib/silcutil/silcutil.[ch].
5040 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Implemented a collision resistant hash table into the
5043 lib/silcutil/silchashtable[ch]. See the header and the source
5044 for the SilcHashTable API.
5046 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Merged dotconf version 1.0.2 into lib/dotconf.
5050 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Do not compile anything in lib/silcsim/* if the SIM support
5053 is not enabled. The tree should now compile without problems
5056 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Compiled the SILC under cygwin. Compiled and tested briefly
5059 without problems. More tests needed. The SIMs didn't compile
5062 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5064 * Fixed possible crash in silc_get_username in the
5065 lib/silcutil/silcutil.c.
5067 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Fixed a va_arg in silc/client_ops.c.
5071 * Oops, RC5 routines were named AES and caused some problems
5072 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5074 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Added new SilcIDIP structure into the lib/silccore/id.h and
5077 replaced the old `ip' fields from all SILC ID's to that type.
5078 This is a step towards IPv6 support.
5080 The silc_id_get_len takes now the ID as an extra argument.
5081 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5082 both IPv4 and IPv6 based ID's.
5084 The affected files are lib/silccore/id.[ch] and other files
5085 around the tree using these routines.
5087 * Removed the ID length arguments in server from various
5088 silc_server_send_notify_* routines -> they are not needed
5091 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Fixed memory leak in silc_encode_pem_file in the file
5094 lib/silcutil/silcutil.c.
5096 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Check minor version as well in the SKE. Affected files are
5099 silcd/protocol.c and lib/silcclient/protocol.c.
5101 * Added --identifier option to the server so that an identifier
5102 can be when creating the public key for the server. Affected
5103 file is silcd/silcd.c.
5105 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5106 lib/silccrypt/silcpkcs.c.
5108 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Register default ciphers and stuff when using -C option with
5111 the server. Affected file sildc/silcd.c.
5113 * Put back the servers public key filename format, it is better
5114 than the new one. For now, the client keys are saved with the
5115 new filename format. The affected file silc/client_ops.c.
5117 * Implemented the Cipher API for the rest of the ciphers that
5118 did not implement it or implemented it the wrong way.
5120 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Register default ciphers and stuff when using the -S option
5123 in the client. Affected file silc/silc.c. Same also when
5124 creating new key pair with -C option.
5126 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Fixed the silc_verify_public_key client operation function to
5129 save the public keys differently. The fingerprint is now
5130 used as filename and not the hostname. This way also the
5131 client keys are saved uniquely and not with hostnames. The
5132 affected file is silc/client_ops.c.
5134 * Trimmed the silc_hash_fingerprint function to remove extra
5135 whitespaces from the end of the fingerprint. The affected
5136 file is lib/silccrypt/silchash.c.
5140 * Added silc_cipher_register_default function to register all
5141 default ciphers. It can be used when configuration files
5142 does not exist and the application does not want any specific
5143 ciphers in any specific order.
5145 The SilcDList is now used as silc_cipher_list dynamically
5146 allocated cipher list. Removed the static list all together
5147 and now all ciphers must be allocated to the dynamic list.
5148 The silc_cipher_alloc routine was changed to check only the
5151 All silc_cipher_* routines that used to return int returns
5154 The affected files lib/silccrypt/silccrypt.[ch].
5156 * The same thing was done to silc_hash_* as for silc_cipher_*
5157 routines. Affected files lib/silccrypt/silchash.[ch].
5159 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5160 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5161 Added also silc_pkcs_[un]register[_default] functions.
5162 Removed the data_context from the PKCS API.
5164 * Added silc_hmac_register_default function to register default
5165 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5166 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5167 to unregister all hmacs at once.
5169 * Register the default ciphers, hash functions, PKCSs and HMACs
5170 if client's configuration file does not exist. The affected
5173 * The client did not load the hash functions from the SIM
5174 modules at all. Added support for this. Affected file is
5175 silc/clientconfig.c.
5177 * When decoding public key with silc_pkcs_public_key_decode, check
5178 the supported algorithm only if PKCS are registered. Affected
5179 file lib/silccrypt/silcpkcs.c. The same was done with the
5180 silc_pkcs_private_key_decode.
5182 * Fixed the SILC List routines to keep the list always in order.
5183 It used to change the list's order when traversing the list but
5184 not it preserves the order. Affected file lib/trq/silclist.h.
5186 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added the client library to use the SilcSocketConnection's
5189 reference counter (by silc_socket_dup) to prevent the bug that
5190 the socket object may be freed underneath async operation.
5192 * The name resolv library checking fixes in the configure.in.pre.
5195 * Created new version of the protocol drafts for future
5196 development. The -03 drafts are the ones that will be changed
5197 in the trunk now and the -02 will remain as they are.
5199 * Send list of CUMODE notifys to the router when announcing
5200 the channel users to the router. Affected file silcd/server.c.
5201 If the router receiving channel founder CUMODE for a channel
5202 that already has channel founder it will send CUMODE notify
5203 to the sender to remove the channel founder rights from the
5204 announced client. Affected file silcd/packet_receive.c.
5206 * The CUMODE notify may now use Server ID as well as the entity
5207 who changes the mode. Updated protocool specs.
5209 * Updated INSTALL and README files.
5211 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * New web pages in the http://silc.pspt.fi. The pages was
5218 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Implemented the [DenyConnectin] config section in the server.
5221 Added silc_server_config_denied_conn to check whether incoming
5222 connection is denied. Affected file silcd/serverconfig.[ch].
5224 * Do not check the ports when checking the incoming configuration
5225 data if the port is 0, meaning any. Affected file is
5226 silcd/serverconfig.c.
5228 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Fixed buffer overflow in silc_string_compare in the file
5231 lib/silcutil/silcutil.c.
5233 * Fixed double free in silc_server_command_leave in the file
5236 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Fixed the version checking in the server. Affected file is
5241 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Fixed the configuration data fetching when accepting new
5244 connections in the server. Affected file silcd/server.c.
5246 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Added `sender_entry' argument to the function
5249 silc_server_packet_relay_to_channel so that we can check
5250 whether some destination actually belongs to the same route
5251 the sender belongs (ie, we must not resend the packet to the
5252 sender). Affected file silcd/packet_send.[ch].
5254 * Added `servername' field to the SilcClientEntry in the server
5255 to hold the name of the server where client is from. Affected
5256 file is silcd/idlist.h.
5258 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Moved the channel message encrypting in the router betwen
5261 router connections from silc_server_channel_message to the
5262 silc_server_packet_relay_to_channel since we want to check
5263 whether we have anybody channel before encrypting anything.
5264 Affected files silcd/packet_[receive/send].c.
5266 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed the [AdminConnection] server config section to support
5269 multiple entries. Affected file silcd/serverconfig.c.
5271 * Added support into the server to check the validity of the
5272 incoming connection before executing any KE or authentication
5275 * The connection configuration is now saved to the KE and
5276 connection auth protocol contexts and not fetched anymore in
5277 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5279 * The local hosts listenning address and port is also resolved
5280 now when starting the server. We want to have the socket object
5281 to include the real address and port for the listener. Added
5282 new function silc_net_check_local_by_sock into the files
5283 lib/silcutil/silcnet.[ch].
5285 * Fixed a broadcast bug in server -> do not broadcast if we
5288 * Fixed a routing bug. Do not route broadcast packets ever.
5289 Broadcast packets must be processed always and not routed since
5290 they may be destined to some other host than yourself and thus
5291 would get routed without no good reason. Affected file is
5294 * Added function silc_server_config_is_primary_route to check
5295 whether primary router connection has been configured (a router
5296 configuration that we are initiating). If there is not, we
5297 will assume that there is only two routers in the SILC network
5298 and we will use the incoming router connection as our primary
5299 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5301 * Changed the order of the broadcasting. Broadcast _after_ the
5302 packet has been processed not before. Affected file is
5305 * Fixed a [ClientConnection] parsing bug. The port was never
5306 parsed correctly thus resulting to port 0. Affected file
5307 silcd/serverconfig.c.
5309 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5310 argument and did not set the broadcast packet flag. Affected
5311 file silcd/packet_send.c. Fixed same bug in the function
5312 silc_server_send_notify as well.
5314 * If we receive NEW_ID packet for our own ID in the server, ignore
5317 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Removed the nickname from the Private Message Payload.
5322 Updated the code and the protocol specs.
5324 * Updated protocol specs for submitting to the IETF.
5326 * Tweaked the Random Number Generator a bit. Affected file
5327 lib/silccrypt/silcrng.c. Exported a new function
5328 silc_rng_[global]_add_noise which can be used to add more
5331 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Do not parse packets with different timeout when protocol
5334 is active -> may cause problem with rekey. Affected file
5337 * When server receives signoff notify it must not create
5338 new channel key if the client is on any channels since the
5339 sender of the signoff notify will create it.
5341 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Added printing of error messages during SKE protocol from the
5344 failure packet sent by server during SKE. Affected file
5347 * Removed the client's failure_callback handling with timeout
5348 and handle it immediately when received.
5350 * The SKE library returned wrong type in SUCCESS and FAILURE
5351 packets. They must be 32 bit MSB not 16 bit MSB.
5353 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Ok, rewrote the logic of the re-key and now it seems to work.
5356 I tested it on high traffic with frequent re-keys without
5357 problems. Added hmac_receive (and renamed hmac to hmac_send)
5358 in SilcClientConnection in lib/silcclient/client.h and
5359 in SilcIDListData in silcd/idlist.h. Also, removed the
5360 SilcPacketParserContext's cipher and hmac fields as they are
5361 not needed anymore and actually caused some problems when
5362 the ciphers and hmac's changed underneath the packet parser.
5364 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * If re-key protocol is active then process the incoming packets
5367 synchronously since we must assure that icoming packets encrypted
5368 with the old key is processed before the new keys is set to
5369 use. This is true other packets than for REKEY packets.
5370 Affected file silcd/server.c. The same was done to client library
5371 as well, affected file lib/silcclient/client.c.
5373 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Fixed bug in client and server to accept the force send if
5376 the packet is send from silc_[server/client]_packet_process
5377 function. Otherwise the packets are never delivered, oops.
5379 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Disable force sending of packets when REKEY protocol is active.
5382 We must assure that no packet is sent directly when rekey is
5383 performed. All packets must be sent through packet queue.
5384 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5385 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5386 function is silc_[server/client]_packet_send_real to check
5389 * Replaced the SIM paths from example config files to
5390 /usr/local/modules. Also, make install creates now
5391 /usr/local/silc/logs directory to hold all the SILC server
5394 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Made the configure.in.pre work on Solaris. Patch by salo.
5398 * Made all ciphers compatible with non-x86 machines. Defined
5399 CBC mode macros into lib/silccrypt/ciphers_def.h.
5401 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Fixed the make install.
5405 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * When MAC computation fails the silc_packet_decrypt returned 0
5408 even though it was supposed to return -1. Fixed this. The
5409 affected file is lib/silccore/silcpacket.c.
5411 * Do not replace the config files in /etc/silc (in make install)
5412 if they already exist. Affected file ./Makefile.am.
5414 * Do not send re-key packets immediately but through packet queue.
5415 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5417 * Changed silc_net_check_host_by_sock to return FALSE if the
5418 IP/DNS could not be resolved. Though, it returns the IP address
5419 now even if it could not resolve it (but returns also FALSE).
5420 Affected file lib/silcutil/silcnet.[ch].
5422 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added silc_pkcs_decode_identifier to decode the public key's
5425 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5426 Added also silc_pkcs_free_identifier. Added also new context
5427 SilcPublicKeyIdentifier.
5429 * Added -S option to the silc client. It is used to dump the
5430 contents of the specified public key file.
5432 * Changed the PKCS api to return the public key length when
5433 setting the public key.
5435 * Fixed a fatal bug in the public and private key file loading.
5436 Affected file lib/silccrypt/silcpkcs.c.
5438 * Execute the packet parsing for client with zero (0) timeout
5439 if the protocol is active. Affected file silcd/server.c.
5441 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Made the key generation options to the silcd program. Added
5444 -C option, equivalent to client's option.
5446 * Added new [ServerKeys] config section to the server. It
5447 configures the server's public and private key.
5449 * Defined generic Public Key Payload into the protocol
5450 specification to send specific type of public keys and
5453 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5454 public key or certificate.
5456 * Implemented the GETKEY command to the server and to the
5457 client library and on user interface.
5459 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Made preliminary `make install' work.
5463 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Added SilcServerRekey context into silcd/idlist.h.
5467 * Added the PFS support as defined in the specification to the
5468 SKE protocol. Affected files lib/silcske/*.c.
5470 * Added `ske_group' field to the SilcServerRekey context to hold
5471 the number of the SKE group that is used with PFS in re-key.
5472 Affected file silcd/idlist.h.
5474 * Added PFS re-key support to the server. Affected file is
5477 * Added silc_protocol_cancel to cancel execution of the next
5478 state of the protocol. Affected file is
5479 lib/silccore/silcprotocol.[ch].
5481 * Added the re-key support with and without PFS to the client
5482 library. Re-key is performed once in an hour, by default.
5484 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5485 Added silc_client_rekey_callback and silc_client_rekey_final.
5486 Affected files are lib/silcclient/protocol.[ch] and
5487 lib/silcclient/client.[ch].
5489 * Removed the `hmac_key' and `hmac_key_len' fields from the
5490 SilcClientConnection structure; not needed. Affected file is
5491 lib/silcclient/client.h.
5495 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Do not ask whether user wants to use the negotiated private key
5498 for private messages, just use it. Affected file is
5499 silc/local_command.c.
5501 * Added `send_enc_key' and `enc_key_len' fields to the
5502 SilcIDListData structure since they are needed in the re-key
5503 phase. Affected file is silcd/idlist.[ch].
5505 * Implemented the simple re-key protocol into the server.
5506 Affected files silcd/server.c and silcd/protocol.[ch]. The
5507 re-key will be performed once in an hour, by default.
5509 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5510 Added silc_server_rekey, silc_server_rekey_callback and
5511 silc_server_rekey_final.
5513 * Removed Tunneled flag from the protocol. Updated the code
5514 and the specifications.
5516 * Adde `pfs' field to the SilcIDListData to indicate whether
5517 the PFS is to be performed in the re-key. Affected file is
5520 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5523 int64 of at least the xintXX size. If void * is less that 4
5524 bytes uint32 * will be used. Defined bool as boolean.
5526 * Changed _ALL_ unsigned long and unsigned int to uint32,
5527 unsgined short to uint16 in the source tree.
5529 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5530 not handle clients that has entry->data.registered == FALSE.
5531 They are not in the network anymore. Affected file is
5534 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Implemented the sending of the SERVER_SIGNOFF notify in the
5537 server. Affected file is silcd/server.c.
5539 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5540 Added also silc_notify_payload_encode_args into the
5541 lib/silccore/silcnotify.[ch].
5543 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5544 Affected file silcd/packet_receive.c.
5546 * Implemented the SERVER_SIGNOFF notify handling in the client
5547 library. Affected file lib/silcclient/client_notify.c. Also,
5548 implemnted the printing of the SERVER_SIGNOFF info to the
5549 application. Affected file silc/client_ops.c.
5551 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5552 if the deleting was successful. Affected file silcd/idlist.[ch].
5554 * Added support for public key authentication in the connection
5555 authentication protocol in the client library. Affected file
5556 lib/silcclient/protocol.c.
5558 * Changed the server's silc_idlist_get_clients_by_* interface
5559 to support already allocated array so that new entries may be
5560 added to pre-allocated array. Affected file silcd/idlist.[ch].
5561 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5562 and command replies.
5564 * All command reply functions in the server now calls the
5565 pending command callback even if error occured. This way the
5566 error will be delivered to the client as well. Affected files
5567 silcd/command.c and silcd/command_reply.c.
5569 * Fixed INFO command to return local server's info if no server
5570 was provided. Affected file lib/silcclient/command.c.
5572 * Removed RESTART command for good. Updated the code and the
5575 * Rewrote parts of the task system. It is a bit simpler now.
5576 Removed unsued task priorities. The affected files are
5577 lib/silcutil/silctask.[ch].
5579 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Moved the USERS printing from the library to the application.
5582 Affected files lib/silcclient/command.c and silc/client_ops.c.
5584 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Added channel key re-key support. The re-key is perfomed
5589 only by the router and is done once in an hour. Added `rekey'
5590 field to the SilcChannelEntry in the server. Affected files
5591 silcd/server.c and silcd/idlist.h.
5593 * Added silc_task_unregister_by_context into the file
5594 lib/silcutil/silctask.[ch].
5596 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added SILC_UMODE_GONE mode to indicate when the client is not
5599 present in the SILC network. Added also support to the local
5600 command AWAY that will set this mode. Added support of showing
5601 "xxx is gone" in WHOIS command. The USERS command shows the
5602 gone status as well.
5604 * Fixed setting server and router operator privileges in the
5605 server's UMODE command. Affected file silcd/command.c.
5607 * Merged the SKE KE1 and KE2 payloads into one payload. The
5608 new KE payload is equivalent to the old KE2 payload.
5610 Cleaned up the SKE Start Payload parsing. It now uses the
5611 simple buffer unformatting to do the parsing. A lot faster
5614 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5615 to the SKE that is used to indicate whether both of the SKE
5616 parties should perform authentication. By default only the
5617 responder performs authentication. By setting this flag also
5618 the initiator must do authentication. By default it is unset
5619 since in normal SKE case, client to server connection, only
5620 the responder should do authentication. When doing SKE between
5621 two clients both should perform authentication. Updated the
5622 code and the protocol specs.
5624 * A little fix to IDENTIFY command in the server. Search the
5625 client first by hash not nickname. Affected file is
5628 * Fixed the silc_client_close_connection to support closing
5629 the client to client connections wihtout deleting too much
5630 data. Affected file lib/silcclient/client.c.
5632 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5633 are received if protocol used to be active but is not anymore
5634 the application would crash due to NULL pointer dereference.
5635 Affected files silcd/server.c and lib/silcclient/client.c.
5637 * Added `hash' field to the SilcClientConnection to include
5638 the hash function negotiated in the SKE protocol.
5640 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5641 to set the channel founder authentication data. A client can
5642 claim the founder rights later by providing the authentication
5643 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5644 This way the channel founder can regain the channel founder
5645 privileges even it is left the channel. This works only on
5646 local server and the client must be connected to the same
5647 server to be able to regain the founder rights. Updated the
5648 protocol specs accordingly.
5650 Added support to the CMODE command in the client to set the
5651 founder auth data. Read the README to see how to set it.
5653 Added support to the CUMODE command to claim the founder
5654 rights. Read the README to see how to do it.
5656 Added support for the founder authentication to the Channel
5657 Entry in the server. Affected file silcd/idlist.h.
5659 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5660 server's CMODE command. Affected file silcd/command.c.
5662 * Added the following new functions into lib/silccore/silcauth.[ch]:
5663 silc_auth_get_method and silc_auth_get_data.
5665 * The server now saves the remote hosts public key to the
5666 SilcIDListData pointer. Affected file silcd/protocol.c.
5668 * The normal server now does not remove the channel entry from
5669 the cache if the founder authentication data is set. It used
5670 to remove it if the founder was the last one on the channel on
5671 the server and left the channel. The auth data is saved and
5672 if the channel is re-joined later the old entry is used with
5673 the old auth data. Affected files silcd/command_reply.c and
5676 * Removed the `pkcs' field from the SilcIDListData structure
5677 in the server; it is not used. Affected file silcd/idlist.h.
5679 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Fixed packet processing on slow links. Partial packets were
5682 never re-processed because the incoming data buffer was cleared
5683 by the application. Application must not directly clear the
5684 sock->inbuf, the packet processing routines handle it. Fixed
5685 this in client library and in server.
5687 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5689 * Fixed the WHOIS and IDENTIFY send reply function to really
5690 check whether to send list or just one entry. Affected file
5693 * Cleaned up the LEAVE command's channel key distribution. The
5694 affected file silcd/command.c.
5696 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5697 can enforce the channel mode as well. In that case the ID
5698 includes the ID of the server. The code now enforces the
5699 mode change if the router have different mode than the server.
5701 * The notify client operation with CMODE_CHANGE notify can now
5702 return NULL client_entry pointer if the CMODE was not changed
5703 by client. Application must check for this.
5705 * Added <Server ID> argument to INFO command to support server
5706 info fetching by Server ID.
5708 * Added silc_server_announce_get_channel_users to get assembled
5709 packets of channel users of the specified channel. Affected
5710 file silcd/server.[ch].
5712 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5713 was freed underneath the ID Cache.
5715 * Re-announce clients when the server received CHANNEL_CHANGE
5716 notify from the router. Affected file silcd/packet_send.c.
5718 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5721 crashed since it did not handle the fact that there is no cipher
5722 called "3" and didn't check the error condition. Now fixed.
5724 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5725 flag. It can be used to send message requests.
5727 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Implemented the RESTART command in the client.
5731 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5732 notice type messages. Added notice printing to the user
5735 * The channel keys are not re-generated if the channel's mode
5736 is PRIVKEY, ie private key on the channel exists. Affected
5737 files silcd/server.c and silcd/command.c.
5739 * Fixed a little bug in channel message delivery when channel
5740 private keys are set in the server. Affected file is
5741 silcd/packet_send.c.
5743 * Changed the setting on channel->on_channel = TRUE from the
5744 silc_client_save_channel_key to the JOIN command reply. The
5745 key payload is not received if the private channel key is set.
5746 Affected file lib/silcclient/command_reply.c and the
5747 lib/silcclient/client_channel.c.
5749 * When the CMODE_CHANGE notify is sent and the channel private
5750 key mode is removed the channel key must be re-generated in
5751 other cells as well. Added this support for the router in the
5752 silcd/packet_receive.c.
5754 * Added new local command NOTICE to send notice message on
5755 channel. Affected file silc/local_command.[ch].
5757 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Added new local command ME to the client. It is used to send
5760 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5761 some action. Affected file silc/local_command.[ch].
5763 * Changed channel_message and private_message client operations
5764 to deliver the message flags to the application. Added also
5765 the `flags' arguments to the silc_client_send_channel_message
5766 and silc_client_send_private_message functions. Affected file
5769 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Redefined the Private Message Payload to support private message
5772 keys and to support the new private message flags. Updated
5773 the protocol specs. Flags makes it possible to have for example
5774 CTCP style messages.
5776 * Added new type SilcPrivateMessagePayload and defined an API
5777 for it in the lib/silcclient/silcprivate.[ch].
5779 * Tested private message private keys successfully. Tested the
5780 private message key set, unset and list commands with the new
5783 * Redefined the Channel Message Payload to include the channel
5784 message flags (equal with private message flags) to support
5785 for example CTCP style messages.
5787 * Defined some of the message (for channel and private message)
5788 flags. Updated the protocol specs and added the flags to the
5789 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5791 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Added SilcKeyAgreementStatus type to the key agreement routines
5794 to indicate the current status and error if one occured.
5795 The status types are defined in the lib/silcclient/silcapi.h.
5797 * Added new local command KEY that is used to set and unset private
5798 keys for channels, set and unset private keys for private messages
5799 with remote clients and to send key agreement requests and
5800 negotiate the key agreement protocol with remote client. The
5801 key agreement is supported only to negotiate private message keys,
5802 it currently cannot be used to negotiate private keys for channels,
5803 as it is not convenient for that purpose.
5805 * Fixed a minor pending callback setting bug in the function
5806 silc_client_get_client_by_id_resolve, now the function works.
5807 Affected file lib/silcclient/idlist.c.
5809 * Added function silc_net_get_local_port to get local bound
5810 port by socket. Added to lib/silcutil/silcnet.[ch].
5812 * Added `sockets' and `sockets_count' fields to the SilcClient
5813 object. They hold the sockets of the listenning sockets in
5814 the client. Listenning sockets may be for example the key
5815 agreement server. Affected file lib/silcclient/client.[ch].
5816 Added functions the silc_client_add_socket and the
5817 silc_client_del_socket. They are exported to the application
5820 * Added ~./silc/clientkeys to support other client's public keys.
5822 * Renamed verify_server_key client operation to verify_public_key
5823 and added one argument to indicate the type of the connection
5824 (server, client etc.).
5826 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Added silc_server_connection_auth_request to handle the
5829 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5830 silcd/packet_receive.[ch].
5832 * Added silc_server_send_connection_auth_request into the
5833 silcd/packet_send.c to send the connection auth request packet.
5835 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5838 * Fixed the public key authentication in responder side in the
5839 server. The `auth_data' pointer includes the SilcPublicKey
5840 not the path to the public key. Affected file silcd/protocol.c.
5842 * Implemented the public key authentication in the initiator side
5843 in the server. Affected file silcd/protocol.c.
5845 * Removed the [RedirectClient] config section from the server
5846 configuration. Is not needed and I don't want to implement it.
5848 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Cleaned up the CMODE command in the server. It now works
5851 correctly and supports all the modes defined in the protocol.
5852 Affected file is silcd/command.c.
5854 * Added `hmac_name' field to the SilcChannelEntry in the server
5855 to hold the default HMAC of the channel. It can be set when
5856 creating the channel (with JOIN command). Affected files
5859 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5860 type to indicate the change of the current cipher and hmac
5861 on the channel. Client can safely ignore the <cipher> argument
5862 (if it chooses to do so) since the CHANNEL_KEY packet will
5863 force the channel key change anyway. The <hmac> argument is
5864 important since the client is responsible of setting the new
5865 HMAC and the hmac key into use.
5867 * Fixed the CMODE command in the client library as well.
5869 * Tested CMODE command in router environment successfully.
5871 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Show the version of the remote client (or server) when connecting
5874 to the server. It is logged to the log file. Affected file
5875 is silcd/protocol.c.
5877 * Fixed the KILLED notify handling in the client library. The
5878 client must be removed from all channels when receiving the
5881 Also, do not remove the client entry when giving the KILL
5882 command but when the KILLED notify is received.
5884 * Removed silc_idlist_find_client_by_nickname from the server.
5885 Not needed anymore. Affected files silcd/idlist.[ch].
5887 * Implemented the CHANNEL_CHANGE notify type handling to the
5888 server. Affected file silcd/server.c.
5892 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added silc_server_send_notify_invite to send the INVITE
5895 notify between routers.
5897 * Implemented the INVITE command correctly to the server.
5899 * Implemented the INVITE notify type handling in the server.
5901 * Implemented the INVITE command to the client library and on the
5904 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added function silc_server_get_client_resolve to find the
5907 client entry by ID from all ID lists and then resolve it
5908 (using WHOIS) if it cannot be found. Affected file is
5911 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Implemented the BAN command to the client library.
5915 * The JOIN command in the server now checks the invite list
5918 * Changed the silc_command_reply_payload_encode_va and the
5919 silc_command_payload_encode_va to support that if argument is
5920 NULL it ignores and checks the next argument. Affected file
5921 lib/silccore/silccommand.c.
5923 * Added silc_server_send_notify_ban to send the BAN notify
5924 type between routers.
5926 * Chaned the silc_notify_payload_encode to support that if
5927 argument is NULL it ignores and checks the next argument.
5928 Affected file lib/silccore/silcnotify.c.
5930 * Tested ban lists in router environment successfully.
5932 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Implemented BAN command to the server, in silcd/command.[ch].
5936 * Removed the BAN and INVITE_LIST modes from the CMODE command
5939 * Added function silc_string_match to regex match two strings.
5940 Affected files lib/silcutil/silcutil.[ch].
5942 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Redefined parts of the SilcChannelEntry in the server to support
5945 the new ban and invite lists.
5947 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Redefined the INVITE command. The same command can be used to
5950 invite individuals to the channel but also to manage the invite
5951 list of the channel (to add to and remove from the invite list).
5952 Updated the protocol specs.
5954 * Added new command SILC_COMMAND_BAN that can be used to manage
5955 the ban list of the channel. Updated the protocol specs.
5957 * Removed the channel modes: the SILC_CMODE_BAN and the
5958 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5959 in the CMODE command. The equivalent features are now available
5960 using INVITE and BAN commands. Updated the protocol specs.
5962 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5963 in the network about change in the current ban list. The notify
5964 type is not used by the client.
5966 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5967 support the invite lists.
5969 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Added new function silc_string_regexify that converts string
5972 including wildcard characters into regex string that can
5973 be used by the GNU regex library. Added into the file
5974 lib/silcutil/silcutil.[ch].
5976 Added silc_string_regex_combine to combine to regex strings
5977 into one so that they can be used as one regex string by
5978 the GNU regex library. Added into the file
5979 lib/silcutil/silcutil.[ch].
5981 Added silc_string_regex_match to match two strings. It returns
5982 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5984 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Imported GNU regex to the soruce tree into lib/contrib.
5987 Fixed some compiler warning from the regex.c.
5989 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Fixed MOTD command in the server to work in router environment.
5993 * Fixed the MOTD command in the client library to support
5994 the server argument in the command.
5996 * Added `nickname_len' argument to the silc_idlist_add_client
5997 in the server, as the `nickname' argument may be binary data
6000 * Added silc_idlist_get_channels to return all channels from
6003 * Implemented LIST command to the server. Affected file is
6006 * Implemented the LIST command to the client library and on the
6009 * Added [<user count>] argument to the LIST command reply.
6010 With private channels the user count is not shown.
6012 * Updated TODO and README.
6014 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * The client entry's data.registered must be TRUE even with
6017 global client entry on global client list. The data.registered
6018 is used to check whether the client is anymore in the network,
6019 for example with WHOWAS command so it must be valid.
6021 * Fixed the WHOWAS command in the server. It now actually works
6022 in router environment. Added function into silcd/command_reply.c
6023 silc_server_command_reply_whowas_save.
6025 * Added silc_idlist_purge function to the silcd/idlist.c
6026 to periodically purge the ID Cache.
6028 * Fixed INFO command in the server. It works now in router
6029 environment. Added <server name> argument to the INFO command
6030 reply. Updated the protocol specs.
6032 * Fixed minor bug in silc_idcache_purge to not purge if the
6033 expire value is zero.
6035 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6036 they were buggy because of the WHOWAS information.
6038 * Fixed local command MSG to handle the async resolving of
6039 the remote client properly. It used to fail the first MSG.
6040 Affected file silc/local_command.c.
6042 * Added `data_len' field to SilcIDCache context.
6044 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Update TODO. Todo in commands in the server.
6048 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6051 used by routers as broadcast packet to inform other routers
6052 about the changed user mode.
6054 Implemented the notify handling in the server. Affected file is
6055 silcd/packet_receive.c. Added the function
6056 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6058 * Added new generic Channel Payload and deprecated the New Channel
6059 Payload. The New Channel Payload is now the generic Channel
6062 * Added new argument `mode' to the silc_server_send_new_channel
6063 as it is required in the Channel Payload now.
6065 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6066 and created a new and real SilChannelPayload to represent the
6067 new generic Channel Payload. Implemented the encode/decode
6068 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6070 * Added silc_server_get_client_channel_list to return the list
6071 of channels the client has joined for WHOIS command reply.
6072 Affected file silcd/server.[ch].
6074 * Implemented the channel list sending in the WHOIS command reply
6075 in server and in the client.
6077 Implemented the channel list displaying on the user interface
6078 as well. Affected file silc/client_ops.c.
6080 * Added silc_channel_payload_parse_list to parse list of Channel
6081 Payloads. It returns SilcDList list of SilcChannelPayloads.
6082 Client for example can use this function to parse the list of
6083 channels it receives in the WHOIS command reply. The caller
6084 must free the list by calling silc_channel_payload_list_free.
6085 Affected files lib/silccore/silcchannel.[ch].
6087 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Added one new argument <user mode> to the WHOIS command reply
6090 to return the mode of the user in SILC. Updated the protocol
6093 Implemented it to the server and client.
6095 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Fixed the mode printing on the user interface on joining.
6098 Affected file silc/client_ops.c.
6100 * Implemented the UMODE command and user modes in general to the
6101 client library and to the user interface.
6103 * Implemented the UMODE command to the server.
6105 * The server now sends UNKNOWN_COMMAND error status if client sends
6106 unknown command. Affected file silcd/command.c.
6108 * All server commands now handle the command identifier the right
6109 way when sending the command reply to the client. The client can
6110 use to identify the command replies with the identifier.
6112 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added silc_server_get_client_route to resolve the route to
6115 the client indicated by the client ID. Affected file is
6118 * Added silc_server_relay_packet as general function to relay
6119 packet to arbitrary destination. This deprecates functions
6120 like _send_private_message_key, _relay_notify etc. Affected
6121 file is silcd/packet_send.[ch].
6123 Removed silc_server_send_key_agreement,
6124 silc_server_send_private_message_key and
6125 silc_server_packet_relay_notify functions from the file
6126 silcd/packet_send.[ch].
6130 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6131 server. Affected file silcd/packet_receive.[ch].
6133 * Implemented the KILL command to the client. Implemented the
6134 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6135 Affected files lib/silcclient/command[_reply].c and
6136 lib/silcclient/client_notify.c. Implemented the KILL notify
6137 printing in the user inteface.
6139 * Fixed a lot silc_parse_nick memory leaks from the client
6140 library in the file lib/silcclient/command.c.
6142 * Changed the silc_server_send_notify_on_channels's `sender'
6143 argument from SilcSocketConnection to SilcClientEntry to
6144 check the sender as entry and not as connection object and not
6145 to send to the client provided as argument. The affected file
6146 is silcd/packet_send.[ch].
6148 * The notify packets that are destined directly to the client used
6149 to not to be processed by the server. Now changed that and the
6150 server processes all notify packets. After relaying the packet
6151 to the client the notify packet is processed in the server.
6153 * The silc_server_free_client_data now checks whether there is
6154 pending outgoing traffic for the client and purges the data to
6155 the network before removing the client entry.
6157 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6160 an client is killed from the SILC Network. Updated the protocol
6163 Added new function silc_server_send_notify_killed to the
6164 silcd/packet_send.[ch].
6166 * Added function silc_server_packet_relay_notify to relay notify
6167 packets that are destined directly to a client. In this case
6168 the server does not process the notify packets but merely relays
6169 it to the client. Affected file silcd/packet_send.[ch].
6171 Added also silc_server_packet_process_relay_notify to check
6172 whereto relay the notify. Affected file is
6173 silcd/packet_receive.[ch].
6175 * Implemented the KILL command to the server.
6179 * Added the backup schema desgined last fall to the protocol
6180 specs for everyone to see. The specification is in the
6181 *-spec-xx.txt draft and the packet type definitions for the
6182 backup routers is in *-pp-xx.txt draft. Thusly, added also
6183 new packet type SILC_PACKET_CELL_ROUTERS.
6185 * A big security problem in the implementation discovered. The
6186 signoff of an client did not cause new channel key generation
6187 which it of course should've done. The channel keys must be
6188 always re-generated when client leaves (or signoffs) the channel.
6189 The silc_server_remove_from_channels funtion now handles
6190 the channel key re-generation.
6192 * Added `sender' argument to the silc_server_send_notify_on_channels
6193 to not to send the client provided as argument. Affected file
6194 silcd/packet_send.[ch].
6196 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Implemented OPER and SILCOPER commands into the server and
6201 * Added silc_auth_verify and silc_auth_verify_data to verify
6202 the authentication directly from the authentication payload.
6203 It supports verifying both passphrase and public key based
6204 authentication. Affected file lib/silccore/silcauth.[ch].
6206 * Added `hash' field to the SilcIDListData structure. It is the
6207 hash negotiated in the SKE protocol. Affected file is
6210 * Slight redesigning of the SilcAuthPayload handling routines.
6211 Do not send SilcPKCS but SilcPublicKey as argument.
6213 * Implemented the public key authentication support to the
6214 serverconfig. The public key is loaded from the provided path
6215 and saved as authentication data to void * pointer. Thus,
6216 changed the unsigned char *auth_data to void *auth_data;
6218 * Fixed SHUTDOWN command to send the reply before the server
6219 is shutdown. :) Affected file silcd/command.c.
6221 * Fixed fatal bug in CONNECT command. The hostname was invalid
6222 memory and server crashed. Affected file silcd/command.c.
6224 * Fixed fatal bug in CLOSE command. The server_entry became
6225 invalid but was referenced later in the command. Affected file
6228 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Fixed fatal bug in failure packet handling. Server ignored
6231 the failure and thus crashed when it came.
6235 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6238 that the command may be executed only once in (about) 2 seconds.
6239 The old SILC_CF_LAG flag is same but allows command bursts up
6240 to five before limiting.
6242 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6243 server code. Various commands now includes the CF_LAG_STRICT
6244 flag to disallow any kind of miss-use of the command.
6246 * Fixed the silc_buffer_unformat to not to allocate any data
6247 if the length of the data is zero. It used to allocate the
6248 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6250 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Changed the format of AdminConnection configuration section
6253 in the server. Added username of the admin to the format.
6254 Affected files silcd/serverconfig.[ch].
6256 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6257 to return admin configuration data by host, username and/or
6260 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Implemented WHOWAS command to the server. Added the functions:
6264 silc_server_command_whowas_parse,
6265 silc_server_command_whowas_send_reply,
6266 silc_server_command_whowas_from_client and
6267 silc_server_command_whowas_from_server
6269 * Added <Client ID> argument to the WHOWAS command reply. Updated
6270 the protocol specs accordingly.
6272 * Implemented WHOWAS command and command_reply to the client
6275 Implemented the WHOWAS printing on the user interface.
6277 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Added new argument to the WHOWAS command reply, the real name.
6280 It is an optional argument. Updated the protocol specs.
6282 * Added SilcIDCacheDestructor callback that is registered when
6283 the SilcIDCache is allocated. The callback is called when
6284 an cache entry in the ID Cache expires, or is purged from the
6285 cache. Added into lib/silccore/idcache.[ch].
6287 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6288 to destruct the client entries when the cache entry expires.
6289 Other ID Cache's in server and in the client library ignores
6292 * If the ID Cache entry's `expire' field is zero then the entry
6293 never expires. Added boolean `expire' argument to the
6294 silc_idcache_add function in the lib/silccore/idcache.[ch].
6295 If it is TRUE the default expiry value is used.
6297 * Added silc_server_free_client_data_timeout that is registered
6298 when client disconnects. By default for 5 minutes we preserve
6299 the client entry for history - for WHOWAS command.
6301 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Added support to the server to enforce that commands are not
6304 executed more than once in 2 seconds. If server receives
6305 commands from client more frequently, timeout is registered
6306 to process the commands. Affected file silcd/command.c.
6307 Added new function silc_server_command_process_timeout.
6309 * Changed NICK_NOTIFY handling in client library to check that
6310 if the client's nickname was changed, so there is no need to
6311 resolve anything from the server.
6313 * Removed error printing from the WHOIS and IDENTIFY commands.
6314 If error occurs then it is ignored silently in the client library.
6315 The application, however, may map the received error to
6316 human readable error string. The application currently maps
6317 the NO_SUCH_NICKNAME error to string.
6319 * Made the command status message public to the application. Moved
6320 them from lib/silcclient/command_reply.c to
6321 lib/silcclient/command_reply.h. The application can map the
6322 received command status to the string with the
6323 silc_client_command_status_message function.
6325 * Added check to the server to check that client's ID is same
6326 as the Source ID in the packet the client sent. They must
6329 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added dist-bzip hook to the Makefile.am to make bzip2
6332 compressed distributions.
6334 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Server now enforces the maximum length for the nickname and
6337 the channel as protocol specification dictates. 128 bytes for
6338 nickname and 256 bytes for channel name.
6340 * Moved the WHOIS printing to the application. The client libary
6341 does not print out the WHOIS information anymore, the application
6342 must do it. Renamed silc_client_command_reply_whois_print to
6343 the silc_client_command_reply_whois_save.
6345 The client's idle time is also sent to the application now, and
6346 the idle is shown on screen.
6348 * Added silc_client_command_reply_identify_save to save the
6349 received IDENTIFY entries.
6351 * Do not check for channel private keys in message sending and
6352 reception if the channel does not have the PRIVKEY mode set.
6353 Affected file lib/silclient/client_channel.c.
6355 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6358 just surfaced after chaning the JOIN procedure.
6360 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Added silc_client_get_clients_by_list to get client entries
6363 from Client ID list, that is returned for example by JOIN
6364 and USERS command replies. The application should use this
6365 function for example when JOIN command reply is received to
6366 resolve the clients already on the channel (library does not
6367 do that anymore as USERS command reply is not used in the JOIN
6368 procedure anymore). Affected files lib/silcclient/silcapi.h and
6369 lib/silcclient/idlist.c.
6371 * JOIN command reply and USERS command reply returns now SilcBuffer
6372 pointers instead of unsigned char pointers when returning
6373 the client list and mode list.
6375 * Added <Client ID> argument to the JOIN command reply, mainly
6376 for the server to identify for which client the command was
6377 originally sent. Updated protocol specs accordingly.
6379 * Added SilcDlist private_key pointer to the SilcChannelEntry
6380 in the client to support the channel private keys. Affected
6381 file is lib/silcclient/idlist.h.
6383 * Added SilcChannelPrivateKey argument to the function
6384 silc_client_send_channel_message so that application can choose
6385 to use specific private ke if it wants to. If it is not provided,
6386 the normal channel key is used, unless private keys are set.
6387 In this case the first (key that was added first) is used
6388 as the encryption key.
6390 * Implemented the support for channel private key handling.
6391 Implemented the following functions:
6393 silc_client_add_channel_private_key,
6394 silc_client_del_channel_private_keys,
6395 silc_client_del_channel_private_key,
6396 silc_client_list_channel_private_keys and
6397 silc_client_free_channel_private_keys
6399 Affected file lib/silcclient/client_channel.c.
6401 * Added the support for the private keys in the channel message
6402 sending and encryption and in the message reception and
6403 decryption. Affected funtions are
6404 silc_client_send_channel_message and silc_client_channel_message.
6406 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Added SKE's key verify callback to the client library's
6409 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6411 * Removed the statement that server (or router) must send USERS
6412 command reply when joining to the channel so that the client
6413 knows who are on the channel. Instead, the client list and
6414 client's mode list is now sent in the JOIN command reply to the
6415 client who joined channel. This is better solution.
6417 * Added function silc_server_get_users_on_channel and function
6418 silc_server_save_users_on_channel to the silcd/server.[ch].
6420 * Removed function silc_server_command_send_users from the
6423 * Do not show topic on the client library anymore. The topic is
6424 sent in the command reply notify to the application and the
6425 application must show the topic now.
6427 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Added client searching by nickname hash into the IDENTIFY and
6430 WHOIS commands in the server as they were clearly missing from
6431 them. Affected file is silcd/command.c.
6433 * Fixed a bug in private message receiving in the client library.
6434 The remote ID was freed and it wasn't supposed, now it is
6437 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6439 * Minor fix to the channel payload; allocate the data area, as it
6440 needs to be of specific length.
6442 * If the key agreement port is zero then the operating
6443 system will define the bound port. Affected files are
6444 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6446 * Added new function silc_channel_payload_decrypt into the file
6447 lib/silccore/silcchannel.[ch].
6449 * Moved the channel message etc, check from silc_packet_decrypt
6450 to applications. The library calls now a generic
6451 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6452 when the packet is either normal or special. This was done to
6453 allow more wide range of checking that was not allowed when
6454 the code was in library. Now applications can do virtually any
6455 checks to the packet and return to the library the decision how
6456 the packet should be processed. Affected files are
6457 lib/silccore/silcpacket.[ch].
6459 Added silc_server_packet_decrypt_check to the server and
6460 silc_client_packet_decrypt_check to the client library.
6462 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6463 to send with specified source and destination information.
6465 * Channel message delivery between routers was broken after the
6466 channel key distribution was fixed earlier. The channel key
6467 was used be to distributed to other routers as well which is not
6468 allowed by the protocol. Now this is fixed and channel keys
6469 really are cell specific and the channel message delivery between
6470 routers comply with the protocol specification.
6472 * Fixed various commands in server to check also the global list
6473 for the channel entry and not just the local list. The affected
6474 file silcd/command.c.
6476 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Added assert()s to buffer formatting and unformatting routines
6479 to assert (if --enable-debug) when error occurs. Affected
6480 file: lib/silcutil/silcbuffmt.c.
6482 * Changed to auto-reconnect to check whether the remote host is
6483 router and register the re-connect timeout if it is. It used
6484 to check that whether we are normal server, but router must do
6485 auto-reconnect with another router as well. Affected file
6488 * Removed the [<key len>] option from CMODE command as the cipher
6489 name decides the key length, nowadays. See the defined ciphers
6490 from the protocol specification.
6492 * Added [<hmac>] option to the CMODE command to define the HMAC
6493 for the channel. Added SILC_CMODE_HMAC channel mode.
6495 * Added [<hmac>] option for the JOIN command so that user can
6496 select which HMAC is used to compute the MACs of the channel
6499 * Added Hmac field to the Channel Message Payload. The integrity
6500 of plaintext channel messages are now protected by computing
6501 MAC of the message and attaching the MAC to the payload. The
6502 MAC is encrypted. Now, it is clear that this causes some
6503 overhead to the size of the packet but rationale for this is that
6504 now the receiver can verify whether the channel message decrypted
6505 correctly and also when private keys are set for the channel the
6506 receiver can decrypt the packet with several keys and check from
6507 the MAC which key decrypted the message correctly.
6509 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6510 lib/silccrypt/silccipher.[ch].
6512 * Added silc_hash_len to return the digest length into the
6513 lib/silcrypt/silchash.[ch].
6515 * Rewrote parts of Silc Channel Payload interface in the
6516 lib/silccore/silcchannel.[ch]. The encode function now also
6517 encrypts the packet and parse function decrypts it.
6519 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Fixed a minor formatting bug in the SKE's key material processing.
6522 It actually might have processed the keys wrong way resulting
6525 * Redefined the mandatory HMAC algorithms and added new algorithms.
6526 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6527 and hmac-md5 truncated to 96 bits. The mandatory is now
6528 hmac-sha1-96. Rest are optional (including the one that used
6529 to be mandatory). Rationale for this is that the truncated HMAC
6530 length is sufficient from security point of view and can actually
6531 make the attack against the HMAC harder. Also, the truncated
6532 HMAC causes less overhead to the packets. See the RFC2104 for
6535 * Added new [hmac] configuration section. The SKE used to use
6536 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6537 is of course wrong. The official names that must be proposed in
6538 the SKE are the ones defined in the protocol specification
6539 (hmac-sha1-96 for example). The user can configure any hmac
6540 using any hash function configured in the [hash] section. At
6541 least, the mandatory must be configured.
6543 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6545 * Added HMAC list to the SKE proposal list. It has now both
6546 hash algorithm list and HMAC list. This makes the protocol
6547 incompatible with previous versions. The SKE now seems to work
6548 the way it is supposed to work, for the first time actually.
6550 * Defined plain Hash algorithms to the protocol specification.
6553 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Implemented support for key agreement packets into the server.
6556 Added functions silc_server_key_agreement and
6557 silc_server_send_key_agreement. Other than these functions,
6558 server has nothing to do with this packet.
6560 * Added support for private message key packets into the server.
6561 Added functions silc_server_private_message_key and
6562 silc_server_send_private_message_key.
6566 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6567 called in the protocol's final callback instead in the END
6568 protocol state. This makes a little more sense and in the same
6569 time in client we can use the same protocol routines for normal
6570 key exchange and to key agreement packet handling as well.
6572 * Added to both client's and server's KE protocol context the
6573 SilcSKEKeyMaterial pointer to save the key material. We will
6574 bring the key material to the protocol's final callback by doing
6575 this. The final callback must free the key material.
6577 * Added SKE's packet_send callback into client's KE protocol
6578 context so that the caller can choose what packet sending function
6579 is used. This way we can use different packet sending when
6580 doing normal SKE when doing key agreement packet handling (in
6581 the key agreement packet handling we do not want to encrypt
6584 * Implemented the responder side of the key agreement routines
6585 in the client. The client can now bind to specified port and
6586 accept incoming key negotiation. The key material is passed
6587 to the application after the protocol is over.
6589 * Implemented the processing of incoming Key Agreement packet
6590 in the client. Added function silc_client_key_agreement to
6593 * Implemented the intiator side of the key agreement routines
6594 in the client. The client can now initiate key agreement with
6595 another remote client. The key material is passed to the
6596 application after the protocol is over.
6598 * Created client_keyagr.c to include all the key agreement
6601 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6602 SILC_TASK_CALLBACK except that it is not static.
6604 * Created client_notify.c and moved the Notify packet handling
6605 from the client.[ch] into that file.
6607 * Created client_prvmsg.c and moved all private message and
6608 private message key routines from the client.[ch] into that file.
6610 * Create client_channel.c and moved all channel message and
6611 channel private key routines from the client.[ch] into that file.
6613 * Changed silc_client_get_client_by_id_resolve to resolve with
6614 WHOIS command instead of IDENTIFY command, in the file
6615 lib/silclient/idlist.c.
6617 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Implemented the SKE's responder side to the Client library.
6621 * When FAILURE is received to the protocol do not trust it
6622 blindly. Register a timeout to wait whether the remote closes
6623 the connection as it should do it, only after that process the
6624 actual failure. This was changed to both client and server.
6626 * Added client_internal.h to include some of the structures
6627 there instead of client.h in lib/silcclient/.
6629 * Added function silc_task_unregister_by_callback to unregister
6630 timeouts by the callback function.
6632 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Some "Incomplete WHOIS info" errors has been appearing on the
6635 log files. Took away the entry->userinfo check from WHOIS
6636 reply sending. The entry->userinfo is now " " if client did not
6637 provide one. I thought this was fixed earlier but something
6638 is wrong still. Let's see if the error still appears.
6640 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Fixed a minor bug in the login when the channel key is
6643 re-generated in the server. It used to generate the key in
6644 wrong order and thus caused problems in the channel traffic.
6646 * Fixed a minor bug in channel key distsribution after
6647 KICK command. The key was not sent to the router even though
6650 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Added silc_ske_process_key_material_data as generic routine
6653 to process any key material as the SILC protocol dictates. The
6654 function is used by the actual SKE library but can be used by
6655 applications as well. This relates to the private message keys
6656 and the channel private keys since they must be processed the
6657 same way the normal SILC session keys. The protocol dictates
6658 this. Affected files: lib/silcske/silcske.[ch].
6660 Added also silc_ske_free_key_material to free the
6661 SilcSKEKeyMaterial structure.
6663 * Defined silc_cipher_set_key function to set the key for
6664 cipher without using the object's method function. The affected
6665 files: lib/silccrypt/silccipher.[ch].
6667 * Implemented silc silc_client_add_private_message_key,
6668 silc_client_add_private_message_key_ske,
6669 silc_client_del_private_message_key,
6670 silc_client_list_private_message_keys and
6671 silc_client_free_private_message_keys functions in the
6674 Added functions silc_client_send_private_message_key to send
6675 the Private Message Key payload and silc_client_private_message_key
6676 to handle incoming Private Message Key payload.
6678 * Added Cipher field to the Private Message Key payload to set
6679 the cipher to be used. If ignored, the default cipher defined
6680 in the SILC protocol (aes-256-cbc) is used.
6682 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6684 * Removed lib/silcclient/ops.h file.
6686 Redefined parts of the SILC Client Library API. Created new
6687 file silcapi.h that deprecates the ops.h file and defines the
6688 published Client Library API. Defined also private message key
6689 API and channel private key API into the file.
6691 This is the file that the application must include from the
6692 SILC Client Library. Other files need not be included by
6693 the application anymore.
6695 * Added new key_agreement client operation callback and also
6696 defined the Key Agreement library API for the application.
6698 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6701 is used by clients to request key negotiation between another
6702 client in the SILC network. If the negotiation is started it
6703 is performed using the SKE protocol. The result of the
6704 negotiation, the secret key material, can be used for example
6705 as private message key.
6707 Implemented the Key Agreement payload into the files
6708 lib/silccore/silauth.[ch].
6710 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Redefined ciphers for the SILC protocol. Added some new ciphers
6713 and defined the key lengths for the algorithms. Changed the
6714 code accordingly. The default key length is now 256 bits.
6716 * Fixed SKE key distribution function silc_ske_process_key_material
6717 when the key length is more than 128 bits. The default key
6718 length in SILC is now 256 bits.
6720 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6721 to indicate unsupported algorithm.
6723 * Renamed rijndael.c to aes.c and all functions as well.
6725 * Fixed a long standing channel key setting bug in client library.
6726 Weird that it has never surfaced before.
6728 * Fixed bug in channel deletion. If the entire channel is removed
6729 then it must also delete the references of the channel entry
6730 from the client's channel list as the client's channel entry and
6731 the channel's client entry share same memory.
6733 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6735 * Implemented CONNECT and SHUTDOWN commands in the client.
6737 * Implemented CLOSE command to the client.
6739 * Added the function silc_idlist_find_server_by_name into the
6740 files silcd/idlist.[ch].
6742 Added the function silc_idlist_find_server_by_conn into the
6743 files silcd/idlist.[ch].
6745 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * DIE command was renamed to SHUTDOWN. Updated the both code
6750 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6751 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6753 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6756 * Added function silc_server_create_connection function to create
6757 connection to remote router. My server implementation actually
6758 does not allow router to connect to normal server (it expects
6759 that normal server always initiates the connection to the router)
6760 so the CONNECT command is only good for connecting to another
6763 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6766 or some other client was kicked from the channel.
6768 Implemented the handling of the notify type to both client
6771 Implemented silc_server_send_notify_kicked to send the KICKED
6772 notify. It is used to send it to the server's primary router.
6774 * Implemented the KICK command into server and client.
6776 * Added `query' argument to the silc_idlist_get_client function
6777 to indicate whether to query the client from server or not if
6780 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6781 to indicate that the client is not channel founder.
6785 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Removed the rng context from SilcPacketContext structure and
6788 changed that the packet routine uses the Global RNG API.
6790 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Added support for quit message that client can "leave" on the
6793 channel when it quits the SILC. It is ditributed inside the
6794 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6796 Added silc_server_free_client_data that will take the
6797 signoff message as argument.
6799 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6801 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Updated parts of the protocol specification to keep it up
6806 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6809 payloads in one packet.
6811 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6812 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6813 use now the new List flag.
6815 * Also deprecated the following packet types: REPLACE_ID,
6816 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6818 * Added list support for Notify packet in server.
6820 * Added silc_server_send_notify_channel_change to send the
6821 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6822 the silc_server_send_replace_id.
6824 * Added silc_server_send_notify_nick_change to send the
6825 NICK_CHANGE notify type. Deprecates the function
6826 silc_server_send_replace_id.
6828 * Added silc_server_send_notify_join to send the JOIN notify type.
6829 Deprecates the function silc_server_send_new_channel_user.
6831 * Added silc_server_send_notify_leave to send LEAVE notify type.
6832 Deprecates the function silc_server_send_remove_channel_user.
6834 * Added silc_server_send_notify_cmode and
6835 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6836 types. Deprecates the silc_server_send_set_mode function.
6838 * Added SERVER_SIGNOFF notify type to indicate that server has
6839 quit. This means that all clients on the channel from that
6840 server will drop. This can be also used when netsplit happens.
6842 Deprecated REMOVE_ID packet type since it is not needed anymore
6845 Added silc_server_send_notify_server_signoff to send the
6846 SERVER_SIGNOFF notify type. Deprecates the function
6847 silc_server_send_remove_id.
6849 Added also silc_server_send_notify_signoff to send the
6850 SIGNOFF notify type.
6852 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6853 SILC protocol from this day on. Changed the protocol
6854 specification as well.
6856 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6857 notify type. It is used between routers to notify about
6858 topic changes on a channel.
6860 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6863 * Partly updated the protocol specification to comply with the
6864 changes now made. It is still though a bit outdated.
6866 * The JOIN notify type now takes one extra argument <Channel ID>.
6867 The packet used to be destined to the channel but now the
6868 JOIN type may be sent as list thus it is impossible to
6869 destine it to any specific channel. By adding this argument
6870 it is again possible.
6872 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Added CREDITS file. The CHANGES and CREDITS file will appear
6875 in the distribution as well.
6877 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6880 types in the server's silcd/packet_receive.c.
6882 * Implemented CMODE and CUMODE to work in router environment.
6884 * Fixed minor encoding and decoding buglet from the
6885 lib/silccore/silcmode.c.
6887 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6890 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6892 * Changed all SilcConfigServer* and silc_config_server* to
6893 SilcServerConfig* and silc_server_config*, respectively.
6896 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6898 * Associated the ID (client or server ID) to the Authentication
6899 Payload to avoid any possibility of forging. Updated the
6900 protocol specification and the code accordingly.
6902 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * The RSA key length is now save to the RsaKey context in the
6905 key generation process in lib/silccrypt/rsa.c. The key length
6906 is now used to figure out the maximum size of the block allowed
6907 to be encrypted/signed.
6909 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6910 is equivalent to the silc_mp_mp2bin but does not allocate any
6913 * Changed silc_mp_mp2bin API to take length argument. If it is
6914 non-zero then the buffer is allocated that large. If zero, then
6915 the size is approximated using silc_mp_sizeinbase, which however
6918 * Created Global RNG API which is global RNG that application can
6919 initialize. After initializing, any routine anywhere in the
6920 code (including library) can use RNG without allocating a new
6921 RNG object. This was done to allow this sort of use of the
6922 RNG in code that has no chance to allocate RNG object. All
6923 applications currently allocate this and many routines in the
6924 library use this. Affected file lib/silccrypt/silcrng.[ch].
6926 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6927 it to use the Global RNG API.
6929 * Defined Authentication Payload into protocol specification that
6930 is used during SILC session to authenticate entities. It is
6931 used for example by client to authenticate itself to the server
6932 to obtain server operator privileges.
6934 Implemented this payload into the lib/silccore/silcauth.[ch].
6935 Implemented also routines for public key based authentication
6936 as the new protocol specification dictates.
6938 Moved definitions of different authentication methods from
6939 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6941 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6942 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6943 silc_pkcs_verify_with_hash functions into the file
6944 lib/silccrypt/silcpkcs.[ch].
6946 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * The client entry's userinfo pointer must be always valid.
6949 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6950 will fail since it requires the userinfo. Now, the userinfo
6951 is allocated as "" if actual userinfo does not exist. Actually,
6952 it must exist and it is totally Ok to drop client connections
6953 that does not announce the userinfo. However, we will make
6954 this workaround for now.
6956 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6957 to return the remote port by socket.
6959 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6962 SILC_SERVER_PENDING_EXEC and added an new macro
6963 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6964 data or when error occurs while processing the pending command.
6966 Added new argument `destructor' into silc_server_command_pending
6967 and to the SilcServerCommandPending object. This destructor is
6968 now called after calling the pending callback or if error occurs
6969 immediately. If error occurs the actual pending callback won't
6970 be called at all - only the destructor. The destructor may be
6971 NULL if destructor is not needed.
6973 All this applies for client library code as well. Similar
6974 changes were made there as well for the pending commands.
6976 In the client, the application must now allocate the
6977 SilcClientCommandContext with the silc_client_command_alloc
6980 * Added reference counter to the SilcServerCommandContext. Added
6981 function silc_server_command_alloc and silc_server_command_dup
6984 Same type of functions added to the client library for the same
6987 * Removed the cmd_ident from IDListData away since it is now
6988 global for all connections. It is the command identifier used
6989 in command sending and with pending commands. The affected file
6992 * Added reference counter to the SilcSocketConnection objecet to
6993 indicate the usage count of the object. The object won't be
6994 freed untill the reference counter hits zero. Currently only
6995 server uses this, and client ignores it. The client must be
6996 set to use this too later. The affected files are
6997 lib/silccore/silcsockconn.[ch]. Added also the function
6998 silc_socket_dup to increase the reference counter.
7000 This was mainly added because it is possible that the socket
7001 is removed underneath of pending command or other async
7002 operation. Now it won't be free'd and proper DISCONNECTING
7003 flags, etc. can be set to avoid sending data to connection that
7004 is not valid anymore.
7006 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7007 the connection. After that it sets SILC_SET_DISCONNECTED.
7008 It is, however, possible that the socket data is not still freed.
7009 The silc_server_packet_process now checks that data is not
7010 read or written to connection that is DISCONNECTED. The socket
7011 get's freed when the reference counter hits zero.
7013 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Changed the client operation API: channel_message operation's
7016 `sender' is now the client entry of the sender, not the nickname
7017 and the `channel' is the channel entry, not the channel name.
7019 In the private_message operation the `sender' is now also the
7020 client entry of the sender not the nickname.
7022 Affected file is lib/silcclient/ops.h and all applications
7023 using the client operations.
7025 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Moved the calling of ops->connect() from connect_to_server_final
7028 into receive_new_id functin since that is the point when the
7029 client is actually allowed to send traffic to network. The
7030 affected file is lib/silcclient/client.c.
7032 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7035 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7036 (if needs broadcasting) instead of broadcasting the packets one
7037 by one which would make a burst in the network traffic.
7039 * Added `broadcast' argument to the functions in silcd/server.[ch]
7040 silc_server_create_new_channel[_with_id] to indicate whether
7041 to send New Channel packet to primary router.
7043 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Added new function into the silcd/server.[ch] files:
7046 silc_server_create_new_channel_with_id to create new channel with
7047 already existing Channel ID.
7049 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7050 lib/silccore/silcpacket.h. This packet is used t send list of
7051 Set Mode payloads inside one packet. Server uses this to set
7052 the modes for the channels and clients on those channels, that it
7053 announced to the router when it connected to it. The protocol
7054 specification has been updated accordingly.
7056 * The silc_server_new_channel did not handle the packet coming
7057 from normal server as it normally does not send that. However,
7058 when it announces its channels it does send it. Implemented
7059 the support for that.
7061 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7062 into the file lib/silccore/id.h.
7064 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * Fixed memory leaks in the functions silc_idlist_del_client,
7067 silc_idlist_del_channel and silc_idlist_del_server in the file
7068 silcd/idlist.c. All of those leaked like a sieve.
7070 * Fixed some small memory leaks in the client's function
7071 silc_client_notify_by_server.
7073 * Added functions into silcd/server.c: silc_server_announce_clients,
7074 silc_server_announce_channels and silc_server_announce_server.
7075 These functions are used by normal and router server to announce
7076 to its primary router about clients, channels and servers (when
7077 router) that we own. This is done after we've connected to the
7080 These functions effectively implements the following packet types:
7081 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7082 and SILC_PACKET_NEW_ID_LIST.
7084 * Added new functions into the silcd/packet_receive.[ch]:
7085 silc_server_new_id_list, silc_server_new_channel_list and
7086 silc_server_new_channel_user_list to handle the incoming
7087 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7089 * Added support of changing Channel ID in the function
7090 silc_server_replace_id. If the server that announces a channel
7091 to the router already exists in the router (with same name but
7092 with different Channel ID), router is responsible to send
7093 Replace ID packet to the server and force the server to change
7094 the Channel ID to the one router has.
7096 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7097 client that the Channel ID has been changed by the router. The
7098 normal server sends this to the client. Client must start using
7099 the new Channel ID as the channel's ID.
7101 Implemented handling of this new type into lib/silcclient/client.c
7102 into the function silc_client_notify_by_server.
7104 * Added new function silc_idlist_replace_channel_id into the files
7105 silcd/idlist.[ch] to replace the Channel ID.
7107 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Call silc_server_command_identify_check always when processing
7110 the IDENTIFY command in silcd/command.c
7112 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7114 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7115 send keepalive packets. The packet can be sent by clients,
7116 servers and routers.
7118 Added function silc_socket_set_heartbeat into the file
7119 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7120 If not set, the heartbeat is not performed. The actual
7121 heartbeat is implemented in the low level socket connection
7122 library. However, application is responsible of actually
7125 Added silc_server_send_heartbeat to send the actual heartbeat
7126 packet into silcd/packet_send.[ch]. Server now performs
7127 keepalive with all connections.
7129 * Added silc_task_get_first function into lib/silcutil/silctask.c
7130 to return the timeout task with shortest timeout. There was a bug
7131 in task unregistration that caused problems. TODO has been
7132 updated to include that task system must be rewritten.
7134 * The client library will now resolve the client information when
7135 receiving JOIN notify from server for client that we know but
7136 have incomplete information.
7138 * Rewrote parts of silc_server_remove_from_channels and
7139 silc_server_remove_from_one_channel as they did not remove the
7140 channel in some circumstances even though they should've.
7142 * Encryption problem encountered in server:
7144 The LEAVE command used to send the Channel Key packet to the
7145 router immediately after generating it. However, the code
7146 had earlier sent Remove Channel user packet but not immediately,
7147 ie. it was put to queue. The order of packets in the router
7148 was that Channel Key packet was first and Remove Channel User
7149 packet was second, even though they were encrypted in the
7150 reverse order. For this reason, MAC check failed. Now, this
7151 is fixed by not sending the Channel Key packet immediately but
7152 putting it to queue. However, this is more fundamental problem:
7153 packets that are in queue should actually not be encrypted
7154 because packets that are sent immediately gets encrypted
7155 actually with wrong IV (and thus MAC check fails). So, packets
7156 that are in queue should be encrypted when they are sent to
7157 the wire and not when they put to the queue.
7159 However, the problem is that the current system has not been
7160 designed to work that way. Instead, the packet is encrypted
7161 as soon as possible and left to the queue. The queue is then
7162 just purged into wire. There won't be any fixes for this
7163 any time soon. So, the current semantic for packet sending
7166 o If you send packet to remote host and do not force the send
7167 (the packet will be in queue) then all subsequent packets to the
7168 same remote host must also be put to the queue. Only after the
7169 queue has been purged is it safe again to force the packet
7172 o If you send all packets immediately then it safe to send
7173 any of subsequent packets through the queue, however, after
7174 the first packet is put to queue then any subsequent packets
7175 must also be put to the queue.
7177 Follow these rules and everything works fine.
7179 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Added new function silc_server_remove_clients_by_server to
7182 remove all client entries from ID list when the server connection
7183 is lost. In this case it is also important to invalidate all
7184 client entires as they hold the invalid server entry. This
7185 fixes fatal bug when server has lost connection and will reconnect
7188 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Made some sanity checks to silc_server_daemonise like to check
7191 whether the requested user and group actually exists.
7193 * Added sanity check to SKE's silc_ske_responder_finish to check
7194 that the public and private key actually is valid.
7196 * Invalidate the client's nickname when receiving Replace ID
7197 packet and the Client ID is being replaced. This means that the
7198 server will query the nickname if someone needs it (client)
7201 * Sort the ID Cache in client library when the ID Cache data
7202 has changed (needs sorting).
7204 * Do not allow for SILC client to create several connections to
7205 several servers. The client does not support windows right now
7206 and generating multiple connections causes weird behaviour.
7208 Irssi-silc client does support windows and can handle several
7209 connections without problems, see: www.irssi.org and SILC plugin.
7211 * Fixed some places where client was added to the IDList. The
7212 rule of thumb is following (in order to get everything right):
7213 If the client is directly connected local client then the
7214 `connection' argument must be set and `router' argument must be
7215 NULL to silc_idlist_add_client function. If the client is not
7216 directly connected client then the `router' argument must
7217 bet set and the `connection' argument must be NULL to the
7218 silc_idlist_add_client function.
7220 * The funtion silc_server_packet_send_local_channel actually did
7221 not check whether the client was locally connected or not. It
7222 does that now. Fixed a bug related to LEAVE command.
7224 * Fixed Remove Channel User payload parsing bug in server's
7225 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7227 * The server's silc_server_save_channel_key now checks also the
7228 global ID list for the channel as it might not be in the local
7229 list. Fixed a bug related to LEAVE command.
7231 * Is this the end of the [<unknown>] buglet that has been lurking
7232 around for a long time? A little for loop fix in server's
7233 silc_server_command_whois_parse that is used by both IDENTIFY
7234 and WHOIS command. At least, this was a clear bug and a cause
7235 of one type of [<unknown>] buglet.
7237 * WHOIS and IDENTIFY commands call the function
7238 silc_server_command_[whois/identify]_check function even if
7239 we are not router server.
7241 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Added --with-gmp configuration option. If set the GMP
7244 is always compiled in the SILC source tree. If not set then
7245 it is checked whether the system has the GMP3 installed. If
7246 it has then the GMP won't be compiled (the system's headers
7247 and library is used), if it doesn't have it then the GMP is
7248 compiled in the SILC source tree.
7250 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7252 * Changed RSA private exponent generation to what PKCS #1
7253 suggests. We try to find the smallest possible d by doing
7254 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7255 not security fix but optimization.
7257 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Added new config entry [Identity] to fork the server and run
7260 it as specific user and group. A patch from Bostik.
7262 * Imported Dotconf configuration library into lib/dotconf.
7263 This will be used to create the SILC configuration files later.
7264 It will appear in the distsribution after this commit.
7266 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * A big code auditing weekend happening. Auditing code for
7269 obvious mistakes, bugs and errors. Also, removing any code
7272 Removed files for being obsolete:
7274 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7275 inline in the file lib/silcutil/silcbuffer.h)
7277 o lib/silcutil/silcbufutil.c (the header has inline versions)
7279 Changed code to fix possible error conditions:
7281 o The buffer formatting routines now check that the destination
7282 buffer really has enough space to add the data. This applies for
7283 both buffer formatting and unformatting
7284 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7285 unformatting was changed to accomodate following rules:
7286 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7287 sent to the function while XXX_*STRING will not allocate or copy
7288 the data into the buffer. Instead it sets the pointer from the
7289 buffer into the pointer sent as argument (XXX_*STRING used to
7290 require that the pointer must be allocated already). This change
7291 makes this whole thing a bit more consistent and more optimized
7292 (note that the data returned in the unformatting with XXX_*STRING
7293 must not be freed now). The routines return now -1 on error.
7295 o Tried to find all code that use buffer_format and buffer_unformat
7296 and added return value checking to prevent formatting and
7297 especially unformatting errors and possible subsequent fatal
7300 o Changed ske->x and ske->KEY to mallocated pointers in
7301 lib/silcske/silcske.h. Fixed possible data and memory leak.
7303 o Added return value checking to all *_parse* functions. Fixed
7304 many memory leaks as well.
7306 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7307 so that buffer overflows would not happen. All code now also
7308 checks the return value as it can fail.
7310 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Added reconnection support to server if the normal server looses
7313 its connection to the router (for example if router is rebooted).
7314 The server performs normal reconnection strategy implemented
7315 to the server. Affected file silcd/server.c.
7317 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Added new packet type SILC_PACKET_SET_MODE that is used to
7320 distribute the information about changed modes (for clients,
7321 channels and clients channel modes) to all routers in the
7322 network. Updated the protocol specification accordingly.
7324 Added functions into silcd/packet_send.c and
7325 silcd/packet_receive.c: silc_server_send_set_mode,
7326 silc_server_set_mode.
7328 Added new files silcmode.[ch] into lib/silccore that implements
7329 the encoding and decoding of Set Mode Payload. Added new type
7330 SilcSetModePayload. Moved the definitions of different modes
7331 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7333 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7335 * Oops, a little mistake in server's connection authentication
7336 protocol. The protocol is not ended with FAILURE but with
7337 SUCCESS if the authentication is Ok. :) Affected file is
7340 * Implemented NICK_CHANGE notify handling in server in the file
7341 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7342 the local clients on the channel. After the changing nickname
7343 in router environment snhould work and the [<unknown>] nickname
7344 should appear no more.
7346 The silc_server_replace_id function that receives the Replace ID
7347 payload now sends the NICK_CHANGE notify type also in the file
7348 silcd/packet_receive.c
7350 * Changed WHOIS and IDENTIFY command to support the maximum amount
7351 of arguments defined in protocol specs (3328 arguments). This
7352 fixed a bug that caused problems when there were more than three
7355 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Added extra parameter, command identifier, to the
7358 silc_client_send_command so that explicit command identifier
7361 Changed that ID list routines uses specific command identifier
7362 when sending WHOIS/IDENTIFY requests to the server so that they
7363 can be identified when the reply comes back.
7365 Affected files lib/silcclient/command.[ch],
7366 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7368 * Added `sender' argument to silc_server_packet_send_to_channel
7369 to indicaet the sender who originally sent the packet to us
7370 that we are now re-sending. Ignored if NULL. Affected file
7371 silcd/packet_send.[ch].
7373 * Added some server statistics support in silcd/server_internal.h
7374 SilcServerStatistics structure and around the server code. Also
7375 send some nice statistics information when client is connecting
7378 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Fixed channel ID decoding in server's JOIN command reply in
7381 silcd/command_reply.c
7383 * Fixed braodcasting of replace ID payload to not to send it if
7384 we are standalone server in silcd/packet_receive.c.
7386 * Fixed all channel message sending routines to not to send
7387 packets to clients that has router set, since they are routed
7388 separately in the same function earlier. Affects file
7389 silcd/packet_send.c and all channel packet sending functions.
7391 * In USERS reply, res_argv[i] are not allocated, the table
7392 is allocated. Thus changed that free the table, not its
7395 * In server's whois_check and identify_check if the client is
7396 locally connected do not send any WHOIS commands - they are not
7399 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Fixed some minor bugs in client when sending WHOIS command. The
7402 arguments was in wrong order.
7404 * Removed statis function add_to_channel from server in
7405 silcd/command.c that was previously used with the joining but
7408 * Tested USERS command in router environment successfully with two
7409 routers, two servers and two clients.
7411 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * Reorganized the USERS command and command reply in client library
7414 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7415 When the command is given by user we register a pending command
7416 callback that will reprocess the command after the reply has been
7417 received from the server. When reprocessing the packet we then
7418 display the information. Thus, the USERS information is displayed
7419 now in the command callback instead of in the command reply
7420 callback. The processing of the command is same as previously
7421 when server has sent the command reply in the JOINing process.
7423 * Added to USERS command in silcd/command_reply.c to join the client,
7424 we didn't use to know about, to the channel after we've created
7425 a client entry for it. Also, for clienet we did know already still
7426 check whether it is on the channel or not and add it if not.
7428 * Removed silc_server_command_join_notify as the function and its
7431 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Changed the client's pending command handling to the same as the
7434 server's pending command handling. It is also now possible to
7435 execute command reply functions from other command reply
7436 function as the function callbacks for commands and command
7437 replies are one and same. The pending commands are not static
7438 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7439 in client connection context. Thus, pending commands are server
7440 connection specific as it is convenient.
7442 Changed the function silc_client_command_pending and
7443 silc_client_command_pending_del and added new function
7444 silc_client_command_pending_check. Removed the
7445 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7448 * Added cmd_ident, current command identifier, to the client
7449 connection context in lib/silcclient/client.h to keep track on
7450 command identifiers used in command sending. Client's command reply
7451 function handling now supports the mandatory command identifiers.
7453 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7454 funtions in client to fully support pending command callbacks.
7456 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7457 as one of the arguments to the application in the command reply
7460 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7461 before first releasing SILC but came back. Now it is removed again
7462 and should come back nomore. The FORWARDED flag was used only
7463 by the JOINing procedure by forwarding the command packet to router.
7464 Now, the JOINing procedure has been changed to more generic (due
7465 to various router environment issues) and FORWARDED is not needed
7466 anymore for anything. The protocol specification is yet to be
7469 Now, removed silc_server_packet_forward from server and the flag
7470 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7472 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7474 * Renamed NAMES command to USERS command. The NAMES was named that
7475 due to historical reasons. Now it is renamed. Also, rewrote
7476 parts of the USERS command. The nickname list is not sent anymore
7477 by the server. Only Client ID and mode lists are sent in the USERS
7478 command. Changed this also to the protocol specification.
7480 The client now resolves the names and stuff after it receives
7481 the USERS list from the server when joining to the channel.
7483 * WHOIS and IDENTIFY commands has been changed to support multiple
7484 Client ID's per command. One can now search for multiple users
7485 in the network by sending only one WHOIS or IDENTIFY command.
7486 Changed the code and the protocol specifications.
7488 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7489 uses silc_server_command_whois_parse to parse the request. */
7491 * If normal server, do not parse the WHOIS and IDENTIFY requests
7492 before sending it to the router. Saves some time.
7494 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7496 * Fixed JOIN command on client library. Wrong number of arguments
7497 used to crash the client.
7499 * Added silc_server_channel_has_global function to check whether
7500 channel has global users or not.
7502 * Added silc_server_channel_has_local function to check whether channel
7503 has locally connected clients on the channel.
7505 * The silc_server_remove_from_one_channel now checks whether the
7506 channel has global users or not after given client was removed from
7507 the channel. It also checks whether the channel has local clients
7508 on the channel anymore. If it does not have then the channel entry
7509 is removed as it is not needed anymore.
7511 * The silc_server_notify now checks on JOIN notify whether the joining
7512 client is one of locally connected or global. If it is global then
7513 the channel has now global users on the channel and that is marked
7514 to the channel entry. Also, it now saves the global client to
7515 global list who is joining and JOINs it to the channel. This is
7516 for normal server, that is.
7518 Changed silc_server_send_notify_on_channel,
7519 silc_server_packet_relay_to_channel and
7520 silc_server_packet_send_to_channel check if we are normal server
7521 and client has router set (ie. global client) do not send the
7522 message to that client, as it is already routed to our router.
7524 * Implemented LEAVE notify type handling in silc_server_notify
7527 * Tested LEAVE command in router environment successfully. Tested
7528 with two routers, two servers and two clients.
7532 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7534 * Implemented SIGNOFF notify type handling in silc_server_notify
7537 * silc_server_remove_id now removes the client entry from all channels
7538 it has joined and thusly sends SIGNOFF notify type.
7540 * Rewrote the NAMES list generation in server by removing two excess
7541 loops. The lists are created now inside one loop.
7543 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7545 * silc_server_remove_channel_user checks now also global list
7546 for channel and client.
7548 * silc_server_new_channel_user checks now both local and global
7549 list for channel and client. Fixed a bug in client id decoding.
7550 Used to decode wrong buffer.
7552 * silc_server_channel_message checks now both local and global
7553 list for channel entry.
7555 * Tested channel joining (hence JOIN) in router environment
7556 successfully. Tested with two routers, two servers and two
7559 * Tested channel message sending in router environment successfully.
7561 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Added silc_server_save_channel_key into server.[ch] to save the
7564 received channel key in Channel Key payload processing. It is
7565 also used in JOIN command reply handling.
7567 Equivalent function silc_client_save_channel_key added into
7568 client.[ch] into client library.
7570 * Changed JOIN command reply to send information whether the channel
7571 was created or not (is existing already) and the channel key
7572 payload. Changed protocol specs accordingly.
7574 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7575 the request was sent by ID and not by nickname. Crashed on
7578 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7580 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7581 now correctly save the received data.
7583 * silc_server_free_sock_user_data now notifies routers in the
7584 network about entities leaving the network.
7586 At the same time implemented functions silc_server_remove_id
7587 and silc_server_send_remove_id to receive and send REMOVE_ID
7588 packets. The packet is used to notify routers in the network
7589 about leaving entities. The ID removed will become invalid in
7592 * Added function silc_idlist_del_server into server. Removes and
7593 free's server entry from ID list.
7595 * silc_server_private_message function now checks, if we are router,
7596 that the destination ID really is valid ID, naturally.
7598 * In router when NEW_ID packet is received (for new client) the
7599 hash of the Client ID is saved in the ID Cache but the
7600 client->nickname is set to NULL, instead of putting the hash
7603 IDENTIFY command now also checks that client->nickname must be
7604 valid. If it is not if will request the data from the server who
7605 owns the client. Added new function
7606 silc_server_command_identify_check.
7608 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7609 to set the command to already allocated Command Payload.
7611 * Tested private message sending in router environment with two
7612 routers, two servers and two clients. Fixed minor bugs and now
7615 * Fixed segfault from client's NAMES command. Used to crash if
7618 * Forwarded packets must not be routed even if it is not destined
7619 to the receiver. Changed server code comply with this.
7621 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added `require_reverse_mapping' boolean value to ServerParams
7624 structure. If TRUE (not default) the server will require that
7625 the connecting host has fully qualified domain name.
7627 If the reverse mapping is not required and hostname could not be
7628 found the IP address is used as hostname.
7630 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Implemented version string checking to both client and server.
7633 The check is incomplete currently due to the abnormal version
7634 strings used in development version of SILC.
7636 * Changed all command functions in server to use the new
7639 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7641 * Changed char *data to unsigned char *data in ID Cache system to
7642 support binary data as ID Cache data. Changed code to support
7643 binary data in lib/silccore/idcache.c.
7645 * Renamed silc_server_packet_relay_command_reply to
7646 silc_server_command_reply as it is normal packet receiving
7647 function. Rewrote the function to accept command replys for
7648 servers and not only for clients.
7650 * Mark remote router always as registered server if we are connecting
7651 to it. Otherwise, commands sent by the router to us are ignored.
7653 * All ID List find routines now returns the ID Cache Entry pointer
7654 as well if requested.
7656 * WHOIS command works now in router environment, tested with two
7657 routers, two servers and two clients.
7659 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7660 in router environment (as it is almost equivalent to WHOIS) but
7661 hasn't been tested thoroughly. Added new functions:
7663 silc_server_command_identify_parse
7664 silc_server_command_identify_send_reply
7665 silc_server_command_identify_from_client
7666 silc_server_command_identify_from_server
7668 * Disabled route cache adding because adding two different ID's with
7669 same IP replaces the old cache entry thus giving wrong route.
7670 The entry->router->connection is always the fastest route anyway
7671 so route cache may not be needed. Of course, new routes maybe
7672 established after receiving the ID when the entry->router->connection
7673 might not be anymore the most optimal.
7675 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Add route cache for received ID for fast routing.
7679 * Added silc_server_packet_route to route received packet on router
7680 that is not destined to us.
7682 * Renamed silc_server_get_route to silc_server_route_get.
7684 * Added id_string and id_string_len fields into SilcServer to
7685 include encoded ServerID for fast comparing without excess
7686 encoding of the ID's.
7688 * Cleaned up WHOIS command on server side. Added following static
7691 silc_server_command_whois_parse
7692 silc_server_command_whois_check
7693 silc_server_command_whois_send_reply
7694 silc_server_command_whois_from_client
7695 silc_server_command_whois_from_server
7697 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7698 arguments in command replies. All command functions should be
7699 updated to use this macro.
7701 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Minor typo fixes on command reply handling on server.
7705 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Added silc_server_command_add_to_channel internal routine to add
7708 the client to the channel after router has created the channel and
7709 sent command reply to the server.
7711 * Added generic silc_server_send_command to send any command from
7714 * Use static buffer with ID rendering instead of duplicating data.
7716 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7718 * Fixed a channel user mode bug when joining to a channel server gave
7719 everybody channel founder rights, oops.
7721 * We mark ourselves as the router of the incoming server connection
7722 if we are router ourselves. This way we can check in some packet
7723 sending functions whether it is locally connected server. For
7724 incoming router connections we put NULL.
7726 * For router sending packets locally means now always sending the
7727 packet cell wide; to local clients and local servers. For normal
7728 server sending packet locally means sending it to only local
7731 * Fixed the JOIN command to really work in router environment. If the
7732 channel is created it is always created by the router. Router is
7733 also responsible of making the initial joining to the channel,
7734 sending JOIN notify to the sending server and distributing
7735 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7736 does not exist server doesn't do anything else but forward the
7737 command to the router which performs everything.
7739 * Added silc_server_send_channel_key function to send the Channel Key
7742 * Added silc_server_create_channel_key to create new channel key. The
7743 channel key is now re-generated everytime someone joins or leaves
7744 a channel, as protocol dictates. Note: channel->key_len is the
7747 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7750 packet_receive.[ch] to separate packet sending and receiving
7751 routines. The server.[ch] now includes everything else including
7752 actual packet processing (writing and reading data) and other
7755 Renamed silc_server_private_message_send_internal to
7756 silc_server_send_private_message. The routine is still though
7757 used only to relay private messages as server does not send
7758 private messages itself.
7760 Renamed silc_server_new_channel to silc_server_create_new_channel
7761 and added new function sicl_server_new_channel that handles the
7762 incoming New Channel packet. Added also new sending function
7763 silc_server_send_new_channel to send New Channel Payload.
7765 * Added new function silc_server_notify to process incoming notify
7766 packet to the server/router. Server may then relay the notify
7767 to clients if needed.
7769 * Added new function silc_server_new_channel_user to process incoming
7770 New Channel User packet. Router will redistribute the packet and
7771 send JOIN notify to its local clients and locally connected servers
7772 if needed. Normal server will send JOIN notify to its local client
7773 on same channel when received this packet. Added also corresponding
7774 sending function silc_server_send_new_channel_user to sent the
7777 * Added boolean route argument to send_notif_to_channel and
7778 packet_send_to_channel functions to attempt to route the packet
7779 if it is TRUE and send only locally if it is FALSE.
7781 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * silc_server_replace_id now broadcasts the received replace ID
7784 packet if it is not broadcast packet already. The router must
7785 broadcast to inform other routers about changed ID.
7787 * Added backpointer to server's router into SilcServer context in
7788 silcd/server_internal.h.
7790 * Fixed silc_server_packet_broadcast to send correct broadcast
7793 * The channel key is now distributed to the local client as soon
7794 as it is received from the router (in router environment) so that
7795 no other packet may be sent for the channel until client has
7798 * silc_server_remove_channel_user now broadcasts the received
7799 Remove Channel User packet if it is not broadcast packet already.
7800 The router must broadcast to inform other routers about removed
7803 * Added users field into SilcPacketContext that is a reference count
7804 of the context. One can increase the reference count by calling
7805 silc_packet_context_dup which is now changed to just increase the
7806 reference count instead of duplicating the data. The reference
7807 count is decresed by calling silc_packet_context_free that will
7808 free the data after the reference count hits zero.
7810 For now on the packet context and everything allocated into it
7811 (including the raw packet from network) must be freed by calling
7812 the new silc_packet_context_free function. Added also new function
7813 silc_packet_context_alloc that must be used now to allocate the
7814 context. This also means that if a routine is asynchronous from
7815 silc_[client/server]_packet_parse_type the packet context must
7816 be duplicated by calling silc_packet_context_dup. Otherwise it
7817 gets free'd after silc_[client/server]_packet_parse_type returns.
7818 Also, one must remember that if packet is duplicated then its
7819 reference count must be decresed by calling the free function as
7820 many times as it was duplicated.
7822 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7823 from both client and server.
7825 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * Made joining to a channel working in router environment.
7829 * Cleaned up JOIN command on server side and create function
7830 silc_server_command_join_channel internal routine to make the
7833 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Changed silc_command_pending list to SilcDList. Also, added
7836 `ident' field to SilcServerCommandPending structure to identify
7837 the reply and to call correct callback.
7839 Added silc_server_command_pending_check function to replace the
7840 corresnponding macro. The silc_command_pending list is not
7843 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7844 to set identifier to previously allocated Command Payload. It
7845 is used to set identifier for command when resending Command
7848 * Added silc_command_payload_encode_payload to encode Command
7849 Payload buffer from SilcCommandPayload structure.
7851 * Added silc_argument_payload_encode_payload to encode Argument
7852 payload buffer from SilcArgumentPayload structure.
7854 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Changed WHOIS command to support router connection on server side.
7857 The whois request is always sent to router unless the server is
7858 standalone server. After server has received the reply from the
7859 router will it send the reply to the client.
7861 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7862 broadcast received broadcast packet. The function is used only
7863 by router. The broadcast packet is always sent to the router's
7866 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7867 render given ID to printable string, for log files for example.
7869 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7871 * Made basic router to router connections working. At least they
7872 can now connect to each other but nothing really works the way
7873 they are supposed - yet.
7875 * Added new initiator token to RouterConnection configuration
7876 file in silcd/serverconfig.[ch]. It is used to tell whether we
7877 are the initiator to the remote router or whether we'll expect
7878 the other end to connect.
7880 * Moved registering of listener task to silc_server_init, hence
7881 the server starts listenning as soon as it is run, even if it
7882 does not have connections to other routers. Let's see how well
7885 * Changed default connection retry timeouts for more suitable in
7888 * Removed cipher and such arguments from silc_idlist_add_client
7889 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7890 Added new function silc_idlist_add_data to add the keys and stuff
7893 * Added SilcIDListData structure and added it to SilcClientEntry
7894 and SilcServerEntry as their first field in the structure. This
7895 way we can explicitly cast the ID entries to the SilcIDListData
7896 structure and get common data for the entries. In past, we had
7897 to first check what type of connection it is and then cast it to
7898 correct ID entry type. Now, we can directly cast the opaque
7899 pointer to the SilcIDListData (no matter what ID entry it actually
7900 is) and get the data needed.
7902 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7904 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7905 in some circumstances even if threre were timeout tasks, though not
7906 IO tasks, but tasks anyway. Now fixed.
7908 * Defined SilcServerConnection structure to hold connection specific
7909 stuff about directly connected servers and routers. The definition
7910 is currently in silcd/server_internal.h. I thought about having
7911 a bit more important role fro this struct but for now it is used
7912 only when connecting to other server (or router actually).
7914 * Added connecting retry support in server when connecting to
7915 router(s). The retry feature implement exponential backoff
7916 algorithm. Also, added SilcServerParams structure to hold default
7917 parameters for server. For now, it include these retry settings
7918 and are hard coded. After server is moded to be as Silc Server
7919 Library this structure will be more important.
7921 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7923 * Changed client librarys channel->clients table to SilcList and
7924 changed code accordingly.
7926 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7928 * Changed client's channel table to SilcList and changed code
7929 accordingly. Also changed SilcChannelClientEntry to include back-
7930 pointer to the channel so that client entry can use that structure
7931 as list as well and we have fast cross-reference to the channel.
7932 This change dramatically decreased the complexity of channel
7933 handling with client entry and vice versa (removed one extra
7934 loop when searching for channel entry from many functions).
7936 * Changed server->sim from table to SilcDList and changed code
7939 * NAMES command can now be used from user interface. It will show
7940 the user list on the channel, neatly.
7942 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7943 Code now saves realname of the user if it becomes available.
7945 * Renamed configure.in to configure.in.pre and made ./prepare
7946 script to automatically add correct version string to
7947 configure.in which it creates from configure.in.pre.
7949 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7951 * NAMES command reply now shows users mode with the nickname when
7954 * Moved silc_client_ch[u]mode[_char] functions from
7955 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7956 place sucks, they are utility functions and should be in some
7959 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7961 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7964 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7968 * Added TRQ (efficient deque and list library) into lib/trq. This is
7969 a very good list library that is currently used in the SILC. Defined
7970 SilcList API over the library because I didn't like the API very
7971 much. See lib/trq/silclist.h for the API and examples of how to
7972 use the API. Fixed various places in the code to use the new
7973 SilcList API. The SilcList is meant for lists that has a structure
7974 already defined as a list. It is not suitable to add just some
7975 context to the list (in TRQ, the context is the list actually).
7977 So, I defined SilcDList that can be used for the purpose where
7978 predefined list structure does not exit. This can be used as
7979 such list. Now some context just can be added to the SilcDList.
7980 Currently this list is not used in the SILC just yet, though there
7981 are a lot places where this can replace dynamically allocated
7982 tables and I will fix these places, later, to use SilcDList.
7983 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7984 and use TRQ internally).
7986 Also fixed some annoying warning messages that the original TRQ
7987 code generated. Also minor changes to TRQ's Makefile.in.
7989 * Added support for querying by Client ID to both WHOIS and
7990 IDENTIFY commands into server, as required by the protocol.
7992 * Removed method function pointers from SilcBuffer structure. They
7993 weren't used to anything and just increased the context size for
7994 no good reason. This change also made silc_buffer_alloc and
7995 silc_buffer_free functions inline functions.
7997 * Disabled command flooding detection support until it's fixed so
7998 that it accepts commands in but does not execute them more than once
8001 * Added silc_net_localhost(), to return local hostname, into
8002 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8003 that must be initialized before calling silc_client_init.
8005 * Added new function: silc_server_send_notify_on_channels to send
8006 notify messages to all channels client has joined. It is assured
8007 that the message is sent only once per client.
8009 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8010 lib/silcutil/silcutil.[ch] as silc_format function. The new
8011 function is generic and is used by server as well, not only by
8012 the logging routines.
8014 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8015 the provided version string was not acceptable. Added new function:
8016 silc_ske_check_version into lib/silcske/silcske.h. The function
8017 must be implemented by the application (client or server) and it
8018 does not reside in the SKE library. The function checks the version
8019 string remote end sent.
8021 * Added back pointers (to opaque context and to SilcSocketConnection)
8022 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8024 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8025 duplicate packet context structure.
8027 * Changed `notify' client operation to send same arguments as client
8028 receives from server except for ID's. ID's are mapped to correct
8029 ID entry and that is returned. Also, if channel entry is not sent
8030 by server but the notify is for channel the channel entry is sent
8031 to application (otherwise application doesn't know that it is for
8032 channel (library gets it from packet's Destination ID)).
8034 * Added silc_client_remove_from_channels into client library to
8035 remove a client from all channels it has joined to. Used when
8036 received SIGNOFF notify from server. Added also new function
8037 silc_client_replace_from_channels to replace old ID entry with
8038 new ID entry on all channels. Used when received NICK_CHANGE
8041 * Fixed ID Cache list handling in silc_idlist_get_client in
8042 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8043 to get (or query) client by ID.
8045 * Updated TODO list.
8047 * Added connection authentication status message defined by the
8048 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8049 support for these into the code in client and server side.
8051 * Added generic function silc_client_send_command to send any command
8052 with variable argument list. Application should use this function
8053 to send commands if the command functions provided by the library
8054 does not suite for the application's user interface needs.
8056 * Added new `failure' client operation. Application is notified about
8057 received failure packet if client is executing a protocol. In this
8058 case the protocol's execution has failed.
8060 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8061 is required by the protocol.
8063 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8064 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8067 * Added status flag to SilcSKE object to indicate realtime status
8068 of the SKE protocol.
8070 * Application receives now exactly same command reply arguments as
8071 the library receives from server. However, if ID is received the
8072 corresponding ID entry is returned to the application (eg. Client
8073 ID is mapped to correct SilcClientEntry entry and that is returned).
8074 Changed command_reply client operation due to this change.
8076 * Changed all ID's in commands and in command replys as ID Payloads.
8077 Change affected both client and server side codes.
8079 All ID's sent in SILC network (with execption of ID's in SILC
8080 Packet header) are sent in ID Payload to support variable length
8083 * Server now notifies nick changes and notifies all clients on
8084 the channels about the new nickname (about the new Client ID,
8087 * Implemented CMODE command to change channel modes. Supports all
8088 channel modes defined by the protocol specs except ban and invite
8089 lists. (Also, private channel key mode is supported but support for
8090 setting private channel key in client is missing, thus, this mode
8091 has no effect on client side (except that server requires that the
8092 client uses private channel key and normal channel traffic does not
8095 Also, invite mode works per se, but INVITE command does not work
8096 yet correctly, so you can set channel as invite only channel but
8097 inviting clients to the channel does not work (it is yet to be
8098 thought what's the best way to do it).
8100 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8101 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8102 Implemented CUMODE command to change user's mode on the channel.
8103 Supports all modes defined by the protocol specs.
8105 * Added NAMES command reply to return users modes on the channel.
8107 * Removed unnecessary and slow ciphers from lib/silccrypt.
8109 * Set SO_KEEPALIVE option to connection sockets by default.
8111 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8113 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8114 redefined the Notify Payload into protocol specs.
8116 * Added silc_id_payload_parse_id to get ID directly from raw
8119 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8122 accept searching by Client ID as well.
8124 * Added support for LEAVE and SIGNOFF notify types in client library.
8126 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8127 to parse ID Payload from raw data.
8129 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * Added flags parameter into silc_ske_assemble_security_properties
8132 function in lib/silcske/silcske.[ch].
8134 * Changed notify client operation to fit better for notify messages
8135 sent by server. The notify payload received from server is now
8136 passed to the application (after parsing it to SilcNotifyPayload).
8137 It is application's responsibility to retrieve the arguments
8138 from the payload and show the message the way it wants. The message
8139 sent by server is implementation specific.
8141 * Changed public keys to comply with the protocol specification.
8142 Old public keys are not supported anymore and are not compatible.
8144 * Removed nickname from Channel Payload as the latest draft removed
8145 it. The client must resolve the nickname from the NAMES command
8146 reply received when it joined the channel.
8148 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8150 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8152 * Fixed some errors in protocol specification drafts.
8154 * Created lib/silccore/silcnotify.c to implement Notify Payload
8155 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8156 generic payloads described by protocol specifications. The file
8157 includes implementations for ID Payload and Argument Payload.
8159 * Changed Command Payload implementation to use the new Argument
8160 Payload. Changed command_xxxx_payload to command_payload_xxxx
8161 to comply with SILC coding conventions.
8163 * Added suppport for Argument Payload handling in Notify Payload
8164 implementation as protocol requires it. Added the new support
8165 into server and client lib as well.
8167 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8169 * Added support for multiple nicknames on same channel. [n] is
8170 added locally to the nickname if there are more than one same
8171 nicknames on the channel.
8173 * Server now sends all nicknames that matched WHOIS request.
8174 Client also shows the list received from server.
8176 * Added TOPIC command to client side. User can now set and show
8177 current topic on channel.
8179 * Added MOTD command to client and server. Also, server sends the
8180 motd when client connects to the server.
8182 * Changed version strings to comply ISO 8601.
8184 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8186 * Fixed protocol error handling in client library. It should now
8187 cope even if the SKE fails for some reason.
8189 * Made new protocol specification drafts for submitting to IETF.
8191 * Implemented TOPIC command to server in silcd/command.c.
8193 * Added two new notify types into lib/silccore/silcnotify.h:
8194 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8195 notify nickname change and topic setting/change on a channel.
8197 * API change of command_reply operation in client library. The
8198 application gets now the status type received from server as well.
8200 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8202 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8204 * Cras fixed and optimized the packet handling even further and
8205 it should work now. Minor change to the prototype of function
8206 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8208 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Added new function into lib/silcutil/silcschedule.[ch]:
8211 silc_schedule_with_fd to select() a specified fd. The function
8212 returns after timeout expires or data arrives or goes. The
8213 function is used by packet routines to wait that all data is
8214 received from network.
8216 * Fixed data reading from network in lib/silccore/silcpacket.c.
8217 The code now assures that all data is read from the fd and then
8218 continues packet processing. This was a bug fix since the code
8219 used to drop some data in some circumstances.
8221 * Added new function into lib/silcclient/client.[ch]:
8222 silc_client_start_key_exchange to start key exchange after
8223 connection has been established to server. The code internally
8224 now uses this funtion but its main purpose was to provide it
8225 for applications that perform their own connecting. After
8226 application has created a connection it merely calls this
8227 function to start the key exchange between client and server.
8228 The library takes care of everything else after that.
8230 Updated also lib/silcclient/README to explain the usage of
8233 * Do not send to application information that connection has
8234 been established. Application gets notified it by connect
8237 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8239 * Applied cras's patch to add silc_schedule_one function. The
8240 function runs scheduler once and returns.
8242 * Fixed the scheduler after cras messed it up. The timeout
8243 handling works now as it's supposed to work.
8245 * Added into lib/silccore/ silcnotify.h to include notify
8246 message types support. Changed silc_server_send_notify*
8247 functions, in server.[ch], to support those new notify types.
8248 Added the support for the notify types into client library,
8249 as well. Added new notify client operation into ops.h in
8252 * Changed silc_server_packet_send_to_channel to send normal
8253 packets instead of just channel message packets. The function
8254 is now used to send the notify packets to channels. It is not
8255 used to send channel message packets anymore, as server never
8258 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8259 va_arg()s as it seems to require it nowadays. I guess, if SILC
8260 is compiled with older va_arg() the new code should work anyway.
8262 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8264 * Splitted core library. Core library (lib/silccore) includes
8265 now only SILC protocol specific core (and common) components.
8266 Created new utility library (lib/silcutil) that includes more
8267 generic purpose stuff. The stuff for util library was taken
8268 from the old core library. This was minor and easy split.
8270 * Created SILC Client Library (lib/silcclient) that includes
8271 implementation of the SILC client without user interface. This
8272 was major move from silc/ directory. The code has been changed
8273 so that it is transparent towards the user interface. The
8274 silc/ directory includes now the same user interface as before
8275 and it uses the new client library. Read lib/silcclient/README.
8276 Basicly, the client library performs everything else related
8277 to SILC except user interface handling. Also, configuration
8278 files are considered to be part of user interface and library
8279 does not handle them.
8281 This change also changed a lot of structures, function naming etc.
8282 Most important change was that SilcClientWindow object was
8283 renamed to SilcClientConnection in the client library. Created
8284 also new file lib/silcclient/ops.h. Also added new files
8285 silc/local_command.[ch] and silc/client_ops.[ch].
8287 All these changes were made to make it easier for user interface
8288 designers to create what ever user interface for the SILC client
8291 It is also expected that the server will be moved to lib
8292 directory as well and SILC Server Library will be created;
8293 sometimes in the future.
8295 * Removed Local commands from lib/silccore/silccommand.h as
8296 they are application specific and new client library does not
8297 handle any of those anymore.
8299 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8300 old client implementation in silc/.
8302 * Added support for callback functions in SILC_LOG_* macros.
8303 Application can now set its own callbacks that will be called
8304 instead of using the default functions that will always print
8305 the debug messages to stderr (or stdout). Also, debugging can
8306 now be disabled by setting silc_debug to FALSE and re-enabled by
8307 setting it to TRUE. Note, that logging will still work even
8308 if debugging is disabled.
8310 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8311 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8312 silc_log_reset_debug_callbacks.
8314 * To enable debugging in silc client one must give now -d
8315 option on command line.
8317 * Changed silc_schedule_init to automatically allocate task queues
8318 if they are not allocated before calling it.
8320 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8322 * Added GMP 3.1 into math library.
8324 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8326 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8327 a channel in SILC network. The packet is used by servers and
8328 routers to notify other routers that user has left a channel.
8329 This little feature was missing until now. Added the feature
8330 to protocol specification as well.
8332 Added functions: silc_server_send_remove_channel_user and
8333 silc_server_remove_channel_user into server.[ch].
8335 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8336 lib/silccore/silcpacket.h. However, they are not implemented
8339 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8341 * Fixed joining to a channel and sending channel messages
8342 between server and router. The channel message sending should
8343 now work inside a cell.
8345 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * Fixed the private message sending between server and router.
8348 The private message sending should now work inside a cell.
8350 * Added silc_server_replace_id into server.[ch] to replace
8351 existing ID in the SILC network.
8353 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8354 and silc_idlist_replace_server_id into idlist.[ch] in server.
8356 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8358 * Fixed the server to server connections. Server can again now
8359 connect to router. Router to router connections probably does
8362 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8364 * Added dynamic protocol registering support. Now protocols can
8365 registered and unregistered on the fly. Patch by cras.
8367 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8369 * Added lib/contrib directory to hold routines that some platforms
8370 don't have but are needed by SILC.
8372 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8373 into lin/contrib to provide getopt() and getopt_long() for
8374 those who don't have it.
8376 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Added AWAY command to client. When away message is set and
8379 client receives a private message packet the client automatically
8380 replies to the sender with the away message.
8382 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8383 bug seemed to be the cause of recent problems when compiling
8386 * Added version detection support to SKE protocol specification
8387 and added the new changes to the SKE implementation as well.
8388 There were other minor changes in the SKE protocol as well.
8390 Many changes in lib/silcske/silcske.[ch] and in
8391 lib/silcske/payload.[ch].
8393 * Added ^U functionality, clear input line. Patch from cras.
8395 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8397 * Mainly small bugfixes on core library. Fixed some debugging
8398 logging and buffer overflow in silclog.c.
8400 * Updated config.sub and config.guess on the distribution tree.
8402 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8404 * Added command lagging support in server. Client may execute
8405 commands now only once in two seconds.
8407 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8409 * Optimized packet reception. MAC computation and checking is now
8410 also more optimized. A lot previously duplicated code is now
8411 used as generic by both client and server.
8413 * Fixed key pair generation in clientutil.c
8415 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8417 * Added into lib/silccore/silcbufutil.[ch] new function;
8418 silc_buffer_realloc.
8420 * Moved generic packet sending/encryption functions to
8421 lib/silccore/silcpacket.[ch] from client and server. Some
8422 rewriting of the functions.
8424 * Moved all generic packet reception/decryption functions to
8425 lib/silccore/silcpacket.[ch] from client and server. The
8426 packet processing is now much cleaner in both client and server.
8427 These were major changes in both client and server.
8429 * Created many common functions in server to do packet sending.
8430 Previously code were duplicated a lot, this has been removed
8433 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Rewrote major parts of the ID cache system. Don't know
8436 whether it is better now or not but at least the API is more
8439 * Major rewrite on ID cache stuff on client because of the ID
8440 cache API changes. Added idlist.c to client.
8442 * Also major rewrite on ID cache stuff on server as well.
8443 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8444 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8445 in hand, instead they are all put into the ID cache system now.
8446 All server_idlist_* routines uses ID cache now instead of
8447 traversing its own lists (those lists does not exist anymore).
8448 SilcIDList though still exists. Also, SilcXXXEntry's are
8451 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8453 * Finally made the SKE implementation compliant to the protocol
8454 specification. All mp integers are now binary encoded as
8455 opposed being HEX encoded.
8457 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8460 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8461 functions: silc_[encode/decode]_pem. Also added function
8462 silc_encode_pem_file to PEM encode with newlines ('\n') for
8465 * SILC public keys are now encoded either PEM or binary. Same
8466 option is for private keys as well. By default private keys
8467 are binary encoded and public keys PEM encoded. Silly HEX
8468 encoding were removed.
8470 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8471 function to create fingerprints.
8473 * Fixed a bug in SHA1; does not change the original data anymore.
8475 * Partly implemented INFO command on client and server side.
8476 Fixed CLEAR command. Changes to SERVER command; show current
8477 server(s) when giving command without arguments. Added
8478 VERSION command to client.
8480 * Added check to server that unregistered connections cannot
8481 execute commands (unless it is specificly allowed).
8483 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8485 * Fixed screen refresh.
8487 * Fixed channel joining bug from client. On some circumstances
8488 client tried to join to a channel it had already joined.
8490 * Added public key verification process into client's protocol.c.
8491 The client now verifies the public key from user and saves
8492 it into ~./silc/serverkeys/ directory.
8494 Added into: clientutil.[ch]: silc_client_verify_server_key.
8496 * Changed SKE protocol's silc_ske_initiator_finish function
8497 to accept callback function that verifies the received public
8498 key. Removed old silc_ske_verify_public_key function.
8500 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8502 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8503 silc_pkcs_private_key[_data]_set.
8505 * Made the password and public authentication more cleaner in
8506 server's protocol.c.
8508 * Removed historic and obsolete protocol `channel_auth' from
8509 both client and server.
8511 * Removed wrong way of sending command status messages from
8512 server to client in server's command.c. The old way violated
8513 protocol specification.
8515 Changes to silccore/silccommand.[ch]: removed
8516 silc_command_encode_status_payload -> not needed anymore,
8517 changed silc_command_encode_payload_va to accept extra
8518 argument on variable argument list. The argument type must
8519 now be provided to the function. Also, added new function:
8520 silc_command_encode_reply_payload_va which is same as
8521 normal command_encode_payload_va except command status type
8522 is provided as extra argument.
8524 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8526 * Added ~./silc directory handling. The directory includes the
8527 public and private keys for the client.
8529 Added silc_client_check_silc_dir, silc_client_create_identifier
8530 and silc_client_load_keys.
8532 * Implemented SILC protocol compliant public key. Added public
8533 and private key saving to and loading from files.
8535 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8536 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8537 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8538 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

8546 * Added silc_server_get_route (route.[ch]) to get connection
8547 data for the fastest route for given ID.

8550 were re-defined in the SILC Protocol Specification and the
8551 implementation now complies with the specification.
8553 * Implemented PING command on client and server.
8555 * Implemented NAMES command on client and server. The server side

8569 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
