516 silcd/command.c, lib/silcclient/command_reply.c. The channel
517 entry is now returned to application in the `command_reply'
520 * Rewrote the version SKE version checking in client libary
521 and in server to use the silc_parse_version_string. Affected
522 files are lib/silcclient/protocol.c, silcd/protocol.c.
524 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
525 commands that was missing it, and updated protocol specs and
526 the server implementation. Protocol TODO #10. The affected
527 file is silcd/command.c.
529 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
530 generic reply to a generic request (REQUEST flag), and
531 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
532 way. A draft-riikonen-silc-flags-payloads-00.txt is written
533 to define the payload for DATA flag. Added the flags to
534 the implementation. Protocol TODO #9. Affected file is
535 lib/silccore/silcchannel.h.
537 Changed the client library to return the message length
538 to application as well in the channel_message and private_message
539 client operations. Affected files are
540 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
541 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
542 and lib/silcclient/client_ops_example.c.
544 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
545 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
546 the channel. Updated protocol specs and impelemented this
547 to client and server. Protocol TODO #6. Affected files are
548 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
549 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
551 Added new options m and M to CMODE command in Irssi SILC
552 client to set these modes.
554 * Deprecated all administrative commands from SILC protocol
555 since they are highly implementation specific commands.
556 Updated protocol specs. Moved the old commands in
557 implementations to private range of command types. Affected
558 files are silcd/command.c, lib/silcclient/command.c and
559 lib/silcclient/command_reply.c. Protocol TODO #8.
561 * Fixed a bug in server where sending unknown command crashes
562 the server. Affected file silcd/command.c.
564 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Added SILC_PROTOCOLVERSION macro to check protocol version
567 of a socket connection. The affected file is
568 lib/silcutil/silcsockconn.h.
570 * Added better error logging in rekey protocol. Affected file
573 * Do not check public key types in SKE during rekey. Affected
574 file lib/silcske/payload.c.
576 * Fixed the rekey protocol with PFS, which was totally broken.
577 Affected file silcd/protocol.c.
579 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Some client implementations quit network by doing first LEAVE
582 and then immediately SIGNOFF (like Bombyx). We now do check
583 after a short time after LEAVE notify and check whether the
584 client is still valid after LEAVE, and if not we remove it from
585 cache. Affected file is lib/silcclient/client_notify.c.
587 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
589 * Merged version 1.1.4 of zlib. Even if it not currently in use,
590 it's good not to have security holes here.
592 * Fixed a negative refcount situtuation for the config context.
593 Affected file is silcd/serverconfig.c.
595 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
597 * ROBOdoc documented lib/silcutil/silcutil.h.
599 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Optimized even more the SilcPacketContext structure. Now
602 totally saved 16 bytes of memory per context after optimization.
603 Affected files are lib/silccore/silcpacket.[ch].
605 * Made strict checks for valid SILC IDs. Affected file is
606 lib/silccore/silcid.c.
608 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Changed the object argument for silc_cipher_register,
611 silc_hash_register, silc_hmac_register and silc_pkcs_register
612 to const. Affected files are lib/silccrypt/silccipher.[ch],
613 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
615 * Changed the silc_get_username and silc_get_real_name to
616 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
618 * Fixed the Irssi SILC Client to use the silc_get_username and
619 silc_get_real_name insted of glib routines since the glib
620 routines only corrupt stack. Fixes the Irssi SILC to work in
621 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
623 * Fixed the Irssi to not use g_get_home_dir since it crashes
624 or returns garbage on cygwin and corrupts stack. Added function
625 get_home_dir to Irssi routines. Affected files are
626 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
628 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Made some structure optimizations. SFTP memory FS MemFSEntry
631 entry structure. Optimized SilcTask structure. Optimized
632 SilcPacketContext structure.
634 Affected files lib/silcsftp/sftp_fs_memory.c,
635 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
637 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * And yet again reverted back the config thing since Johnny
640 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
643 * Fixed memory leaks from config object. Affected files are
644 silcd/serverconfig.[ch].
646 * Added support for adding new connections to the server in rehash.
647 After rehash they take effect.
649 Added support for changing the maximum allowed connections in
650 rehash. The number can grow but going smaller is not supported.
652 Added function silc_server_num_sockets_by_remote to the
653 silcd/server_util.[ch].
655 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
657 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
659 * Added preliminary checking during config parsing for a valid
660 public/private key and removed further checks in the code.
661 Affected files are silcd/serverconfig.[ch], server.c.
663 * Moved functions silc_server_drop() and silc_server_daemonise()
664 from server.c to silcd.c since they are stricly related to
665 the application activity.
667 * Reverted a small part of the automatic ref/unref since
668 it caused a double unref in some situations. Affected
669 files are silcd/silcd.[ch], server.c, serverconfig.c.
671 * Added some .cvsignore files in the lib directory.
673 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
675 * Fixed silc_net_gethostbyaddr to correctly resolve by
676 address. Affected file lib/silcutil/silcnet.c.
678 * Fixed the notify relaying to client. The HMAC to be used
679 with relayed packets ws wrong and caused decryption failure
680 at the client end. Affected file is silcd/packet_receive.c.
682 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
684 * Created new branch silc_protocol_1_0_branch.
686 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
688 * Changed the silc_server_config_* routines to be SilcServer
689 independent. They are now officially application specific code
690 and not part of generic server implementation. Affected files
691 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
693 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Added automatic referencing of config context in the
696 silc_server_config_alloc, and automatic unreferencing in the
697 silc_server_config_destroy. Affected files are
698 silcd/serverconfig.[ch], silcd/silcd.c.
700 * Fixed the silc_log_quick handling in the logging routines.
701 It didn't log quickly when it was TRUE. Affected file is
702 lib/silcutil/silclog.c. Also the flush delay was set even
703 if it was 0 in config file. Affected file is
704 silcd/serverconfig.c.
706 * Added support for changing key pair of the server in rehash.
707 Affected file silcd/server.c.
709 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Fixed the TOPIC_SET notify to not cras. It changed the topic
712 too early, before getting the channel entry. Affected file
713 is silcd/packet_receive.c.
715 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
717 * Added functions silc_server_config_[ref/unref], these are used
718 to prevent that the config object is destroyed.
720 No longer directly affect global variables silc_log_quick and
721 silc_log_delay, they are first cached inside the config object
722 and then applied with silc_server_config_setlogfiles().
724 silc_server_config_set_defaults() is now internal to
725 serverconfig.c, there are no reasons to show this internal stuff
728 Affected files are silcd/serverconfig.[ch].
730 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
731 fprintf's to stderr, since some code may be executed again after
732 the server went into the background. Affected files are
735 * Added rehash support. Added function silc_server_rehash() that
736 will perform all the basic tasks of the rehashing procedure.
738 * Added command line option `-x, --hexdump'. This will enable the
739 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
740 The option `--hexdump' implies `--debug'.
742 * Fixed a bad bug in the logging APIs (silcutil library) where
743 the application would crash after calling silc_log_reset_all().
745 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Fixed the KICKED notify handling in client library to
748 correctly remove the channel and all entries from the
749 channel when I was kicked. This bug crashed the client.
751 Fixed yet another but in KICKED notify handling to remove
752 the kicked client correctly from the channel.
754 Affected file is lib/silcclient/client_notify.c.
756 * Fixed a minor bug in looking up correct client entry
757 in KICKED notify in server. Affected file is
758 silcd/packet_receive.c.
760 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
761 sources correctly to distribution. Fixes --with-gmp option.
763 * Removed the manual rehashing from ID Cache, and changed it
764 to use the SILC Hash Table's auto rehash feature. Affected
765 file is lib/silccore/silcidcache.c.
767 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
769 * Fixed a bug in the silc_client_nickname_format function that
770 handles the multiple same nickname formatting. Two clients
771 with same nickname caused problems after the first one left
772 and rejoined. It didn't format the nickname correctly.
773 Affected file is lib/silcclient/idlist.c.
775 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Don't change the topic if olod topic is same as new one.
778 Affected file is silcd/packet_receive.c.
780 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
782 * Added cross-reference support to the SILC Documentation
783 generator. All types across all HTML files are now cross-
784 referenced. Affected files util/robodoc/generator.c and
785 scripts/silcdoc/silcdoc.
787 * Added file lib/silcutil/silctypes.h to include all the
788 arithmetic type definitions and some macros. Removed
789 includes/bitmove.h and moved macros to silctypes.h.
791 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
795 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Added `type' argument to silc_id_payload_parse_id function which
798 now returns the type of the ID to the sent pointer. Affected
799 file is lib/silccore/silcid.[ch].
801 * Added check for CMODE_CHANGE notify type that mode change is
802 allowed by the sender. Affected file silcd/packet_receive.c.
804 * Added check for CUMODE_CHANGE notify type that mode change is
805 allowed by the sender. Affected file silcd/packet_receive.c.
806 Added the ID type as CUMODE_CHANGE notify type as argument
807 to the `notify' client operation. Affected files are
808 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
810 * Added function silc_client_add_server to the client library.
811 Added support for resolving also channel and server info when
812 received unknown entity in notify packet. Affected files are
813 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
815 * Added function silc_command_get_status to return the command
816 status from the command reply's argument payload. Affected files
817 are lib/silccore/silccommand.[ch].
819 * Added check for KICKED notify type that the kicking is
820 allowed by the client. Affected file silcd/packet_receive.c.
822 * Created function silc_get_input which can be used to get input
823 (echo on or off) from user on command line. Affected files are
824 lib/silcutil/silcutil.[ch].
826 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Optimized silc_server_packet_relay_to_channel function.
829 Added new function silc_channel_message_payload_encrypt which
830 can be called directly if channel message payload needs to
831 be encrypted and is already encoded (no need to call _encode
832 function). Packet relaying is now done by router without any
833 extra memory allocations. Affected files are
834 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
837 * Fixed the INVITE notify handling. It took wrong arguments
838 as invite list and invite delete. Affected file is
839 silcd/packet_receive.c.
841 * Added check for TOPIC_SET notify type that the topic change is
842 allowed by the client. Affected file silcd/packet_receive.c.
844 * Added check for INVITE notify type that inviting is allowed by
845 the client. Affected file silcd/packet_receive.c.
847 * Changed the silc_server_client_on_channel to return the
848 SilcChannelClientEntry as well. Moved the function
849 silc_server_check_cmode_rights to server_util.[ch].
850 Affected files are silcd/server_util.[ch], silcd/command.c.
852 * Added function silc_server_check_umode_rights to check whether
853 changing client's user mode is allowed. Added check for
854 UMODE_CHANGE notify type that the umode change is allowed
855 by the client. Affected files are silcd/server_util.[ch],
856 silcd/packet_receive.c and silcd/command.c.
858 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
860 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
861 ID length. It ignored that ID can be IPv6 based as well.
862 Affected file lib/silccore/silcpacket.h.
864 * Fixed the silc_id_id2str and silc_id_str2id to take the
865 IPv6 address offset's into consideration. Affecte file is
866 lib/silccore/silcid.c.
868 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed the internal Unix scheduler functions to check for
871 NULL context they may receive. The affected file is
872 lib/silcutil/unix/silcunixschedule.c.
874 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
876 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
877 can specify different directory with --home command line
878 parameter. Affected files irssi/src/silc/core/client_ops.c,
881 * SILC-specific commands aren't now executed if the active server
882 isn't of SILC-type, so there won't be problems with having
883 IRC and SILC protocol support in same client. Affected files
884 irssi/src/silc/core/silc-channels.c, silc-servers.c,
887 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
889 * Improved the signal support in SILC Schedule. Added new
890 function silc_schedule_signal_call which is used by application
891 to mark a signal to be called. It is now safe to perform
892 any kind of tasks in signal callbacks since it is guaranteed
893 that the application specified signal callback is called
894 after the signal is over. Affected files are
895 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
897 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
899 * Added `name' field to SilcChannelPrivateKey to represent
900 application given name for the key. Moved also the context from
901 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
902 Added the `name' argument also to the function
903 silc_client_add_channel_private_key.
905 Added function silc_client_current_channel_private_key to set the
906 current channel private key in use.
908 Added "change" command to KEY command which can be used to change
909 the current channel private key. Bound the command also to
912 Also affected files lib/silcclient/client_channel.c,
913 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
915 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
917 * Added silc_rng_get_byte_fast function in to the
918 lib/silccrypt/silcrng.[ch].
920 * Changed the interface of silc_packet_assemble and the
921 silc_packet_send_prepare. If silc_packet_assmble is now
922 called the application does not call silc_packet_send_prepare
923 because the library will call it automatically. These
924 interfaces now also return a reference to the outgoing buffer
925 which includes the assembled packet, which the application can
926 use to encrypt the packet.
928 Affected files are lib/silccore/silcpacket.[ch],
929 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
930 silcd/packet_send.c, server_backup.c and packet_receive.c.
932 * Fixed a packet sending bug on very high load, where outgoing
933 packet queue wasn't handled correctly and packets got corrupted.
934 Affected files are lib/silcutil/*/silc*sockconn.c,
935 lib/silcclient/client.c and silcd/server.c.
937 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Added macro SILC_PACKET_DATALEN which can be used during
940 packet assembling to check whether the data to be added to
941 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
942 len is truncated until it fits it.
944 Added checks for maximum length of channel message payload and
945 private message payload also.
947 Added checks for maximum packet length in server and in
950 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
951 lib/silcclient/client.c, lib/silccore/silcchannel.c and
952 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
953 lib/silcclient/client_prvmsg.c.
955 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
957 * Added silc_server_packet_queue_purge call to the
958 silc_server_disconnect_remote to assure that all data in the
959 queue before disconnecting is sent to the network. Affected
962 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
964 * Added the deleting of server's own ID cache entry to the
965 silc_server_free function. Free also everything else that
966 has been allocated in silc_server_init. The affected file
969 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Added functions silc_parse_version_string, silc_version_to_num,
972 and silc_ske_parse_version to parse SILC protocol style version
973 strings. Affected files lib/silcutil/silcutil.[ch] and
974 lib/silcske/silcske.[ch].
976 * Added new configuration params: version_protocol, version_software
977 and version_software_vendor to specify what version the remote
978 host must at least be to be able to connect to server. The vendor
979 string can be regex matched too. Added new function
980 silc_server_connection_allowed to check maximum number of allowed
981 connections, and allowed versions for incoming connections.
982 Affected files are silcd/server.c, server_util.[ch] and
985 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Added preliminary support for signals in scheduler. The
988 signals we care about are now blocked always when the scheduler
989 is locked. This way we can synchronise the use of signal with
990 scheduler. It is guaranteed that when signal occurs the scheduler
991 is not locked, and thus new tasks can be safely added to the
994 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
995 to silc_schedule_internal_init and silc_schedule_internal_uninit.
996 Added new platform specific routines
997 silc_schedule_internal_signals_[un]block and
998 silc_schedule_internal_signal_[un]register.
1000 Added new functions to SILC Schedule API:
1001 silc_schedule_signal_[un]register. Each signal that application
1002 is going to use should be registered to the scheduler.
1004 Affected files are lib/silcutil/silcschedule.[ch],
1005 lib/silcutil/*/silc*schedule.c.
1007 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1009 * Check for unauthenticated client and server in the
1010 silc_server_new_client and silc_server_new_server functions.
1011 Affected file silcd/packet_receive.c.
1013 * Added function silc_string_is_ascii to check whether given
1014 string is 7-bit ASCII string. Affected files are
1015 lib/silcutil/silcutil.[ch].
1017 * Added function silc_id_is_valid_server_id into the
1018 silcd/serverid.c and added checking for valid Server ID's in
1019 silc_server_new_server. The Server ID must always be based
1020 on the server's public IP address.
1022 * Added logging of DISCONNECT packet message in the server.
1023 Affected file silcd/server.c.
1025 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Changed all library interfaces that use Global RNG to also
1028 accept SilcRng as argument. Affected files are
1029 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1030 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1031 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1032 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1033 lib/silccrypt/rsa.c.
1035 * Added function silc_pkcs_generate_key to the
1036 lib/silccrypt/silcpkcs.[ch] for applications so that they
1037 don't need to do pkcs->pkcs->init calls anymore.
1039 * Remove SilcSocketConnection from the SFTP API since it really
1040 wasn't needed there. The application has the information
1041 saved in its contexts anyway and the SFTP layer doesn't need
1042 know about it. Affected files lib/silcsft/silcsftp.h and
1043 lib/silcsftp/sftp_[server/client].c.
1045 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1046 The SilcSimContext is not SilcSim.
1048 * Fixed possible buffer overflows in silc_id_render in the
1049 lib/silcutil/silcutil.c.
1051 * On EPOC the global crypto module lists are not used at all
1052 in the crypto library. Added support for using the constant
1053 algorithm list on EPOC. Affected files are
1054 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1057 * Fixed the handling of third parameter of KICKED notify, since
1058 it was mistakenly updated to SILC Protocol 1.0 even though it
1059 is to be included in 1.1. Since it is not in 1.0 it is not
1060 mandatory, and this fix now handles it only if it is provided,
1061 and it is not error if it is not provided. Affected file
1062 lib/silcclient/client_notify.c.
1064 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1066 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1067 client. Affected file irssi/src/silc/core/client_ops.c.
1069 * Merged with Irssi 0.8.4 from irssi.org CVS.
1071 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1073 * Check for valid socket connection in client entries before
1074 sending any messages. Fixes a crash, but doesn't fix some
1075 other underlaying bug that is lurking there. Affected
1076 file silcd/packet_send.c.
1078 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1080 * $usermode, $cumode and $cumode_space expandos shouldn't do
1081 anything with non-SILC server records. Affected file
1082 irssi/src/silc/core/silc-expandos.c
1084 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1086 * Fixed the silc_net_check_[host/local]_by_sock to support
1087 IPv6 bound sockets as well. Now they can return IPv6 addresses
1088 as well. Affected file lib/silcutil/silcnet.c.
1090 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1091 Affected lib/silcutil/unix/silcunixnet.c.
1093 * Fixed ID rendering (at least on some platforms, not NetBSD)
1094 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1096 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1098 * Added silc_hash_public_key and silc_hash_public_key_compare
1099 functions to be used with SilcHashTable. They can be used to
1100 hash public keys and compare public keys in hash table. Affected
1101 file lib/silcutil/silcutil.[ch].
1103 * Added support for specifying multiple public keys for Client
1104 connection section in server configuration file. This makes it
1105 possible to accept multiple public keys from same host, or to
1106 make a section that accepts any incoming host, and have the
1107 accepted public keys listed in the section.
1109 Added functions silc_sever_[find/get]_public_key, added the
1110 support for this actually to all connection sections but only
1111 the Client section is currently allowed to specify multiple
1114 Affected files are silcd/server.c, server_internal.h,
1115 command.c, protocol.c, server_util.[ch], packet_receive.c.
1117 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1121 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1123 * If silc_debug is TRUE, also output standard logging messages
1124 to stderr with the debug output.
1126 Made silc_log_reset_all() flushing all channels before returning.
1127 Also fixed some documentation typos.
1129 Affected files are lib/silcutil/silclog.[ch].
1131 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Fixed the server to check correctly the amount of connections
1134 from single host, by checking also the type of the connection.
1135 Fixed also the comparison of number of connections and number
1136 of allowed connections. Affected files are silcd/server.c,
1139 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Fixed the USERS command reply to save the user's mode on the
1142 channel as well. Fixed JOIN command reply to check whether a
1143 client is on channel already and not join it twice. Affected
1144 file lib/silcclient/command_reply.c.
1146 * Added new file silc-expandos.c into irssi/silc/core/ to return
1147 various stuff for various signal for the statusbar etc. updating.
1148 Now Irssi SILC client prints channel user modes etc. on the
1151 * The user mode (like server/router operator changes) is now shown
1152 on the Irssi SILC client's statusbar. The affected files are
1153 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1155 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1158 to SILC_SCHEDULE_[UN]LOCK macros.
1160 * Added more error printing to logs in server code. Affected
1161 files silcd/server.c and silcd/protocol.c.
1163 * Fixed -S option parsing in Irssi SILC Client. Affected file
1164 irssi/src/silc/core/silc-core.c.

1191 * Changed all integer type names:
1192 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1193 to avoid collisions with other libraries using same type names
1196 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Added `prefer_ipv6' argument to the functions
1199 silc_net_gethostbyname[_async]. If it is TRUE it will return
1200 IPv6 address over IPv4. If FALSE IPv4 address is returned
1201 even if IPv6 address was found. Affected files
1202 lib/silcutil/silcnet.[ch].
1204 * Added support silc_net_create_connection[_async] to fallback
1205 to IPv4 address if IPv6 address could not be used (like if
1206 it doesn't work on a specific system). Affected file in
1207 lib/silcutil/unix/silcunixnet.c.
1209 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1215 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1217 * Added automatic extern "C" { ... } for C++ compilers so the
1218 application does not need to define them. Affected file
1219 includes/silcincludes.h.
1221 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1222 old name went against naming convention. Applications now
1223 include "silcclient.h" instead of "clientlibincludes.h".
1224 Removed includes/clientlibincludes.h, it is redundant now.
1226 * Renamed includes/version.h to silcversion.h.
1228 * Added really preliminary support for OS/2 into the util
1229 library. Only thread & mutex API is implemented, others
1230 are still to be implemented. Created the lib/silcutil/os2/
1231 directory. Created also file includes/silcos2.h.
1233 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1238 includes/silcbeos.h.
1240 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1242 * Added proper initializations to silc's irssi code, so it's
1243 now possible to load it as module. Affected files
1244 irssi/src/silc/core/silc-core.c,
1245 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1264 * Added `user_count' to the SilcChannelEntry which now tells the
1265 number of users on the channel. The user count is now saved
1266 in normal server of global channels as well. Affected files
1267 silcd/server.c, idlist.h, packet_receive.c and command.c.
1269 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1270 include file utility functions.
1272 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1273 instead of calling directly OS routines.
1275 * Fixed NICK change printing in Irssi SILC Client. Fixed
1276 KICKED notify printing in Irssi SILC Client. Affected file
1277 irssi/src/silc/core/client_ops.c.
1279 * Fixed a NICK change bug in client library, to not recreate the
1280 client_entry->channels hash table everytime nick is changed.
1281 Affected file lib/silcclient/client.c.
1283 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1285 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1286 the SKE interface a bit.
1288 * Fixed padding problem in PKCS#1. The padding was not actually
1289 random since the random number generator was used incorrectly.
1290 This security bug affects only when encrypting with PKCS#1, and
1291 it is not currently used at all in SILC. SILC only use signing
1292 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1294 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1305 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1306 key_exchange_timeout, conn_auth_timeout, connections_max,
1309 Implemented all the new config settings handling in the server.
1311 Optimized the use of SKE Mutual flag usage. Use it only
1312 if connection authentication protocol is not based in public
1315 Renamed all SilcServerConfigSection* to SilcServerConfig*
1316 to have a bit shorter names.
1318 Affected files silcd/serverconfig.[ch], server.[ch], and
1321 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1340 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1342 * Removed param_name member from client, server, and router
1343 section structs, now identifying the param directly.
1345 Added CONFIG_FREE_AUTH macro in config file parsing.
1347 Affected files are silcd/serverconfig.[ch].
1349 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1351 * Fixed command line parameter handling. All SILC initialization
1352 is now done in silc_core_init() which also fixes autoconnecting
1355 Affected files irssi/src/silc/core/silc-core.c,
1356 irssi/src/fe-text/silc.c.
1358 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1360 * Added new configuration options and blocks:
1361 keepalive_secs, reconnect_count, reconnect_interval,
1362 reconnect_interval_max, reconnect_keep_trying and
1363 require_reverser_lookup. Added ConnectionParam block, and
1364 implemented the connection parameters when connecting as
1365 initiator and when accepting connections as responder.
1367 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1368 whether given configuration value has been given already.
1370 Affected files silcd/serverconfig.[c], server.[c].
1372 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1373 algorithm parts and created new file silcalgs.conf, that
1374 is now included from the example_silcd.conf.in.
1376 * Optimized the silc_server_connect_to_router_second to take
1377 the connection configuration object from the SilcServerConnection
1378 object instead of finding it during the connecting phase.
1379 Added the configuration object to SilcServerConnection struct.
1380 Affected files silcd/server_internal.h, server.c.
1382 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Add the client on channel after it was resolved at the
1385 channel message receiving, and it was not already on the
1386 channel. Affected file lib/silcclient/client_channel.c.
1388 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1390 * Fixed the public key authentication to allocate always the
1391 destination signature buffer instead of using static buffer.
1392 Affected file silcd/protocol.c.
1394 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1403 config file, allowing both public key and passphrase based
1404 authentication to be set at the same time.
1406 Added `prefer_passphrase_auth' setting in config file which
1407 can be used to set to prefer passwd auth if both passwd and
1408 public key is set. If not set, public key is preferred.
1409 This has effect only when being initiator (responder will try
1412 Added support for authentication with passphrase and public key
1413 at the same time. The passphrase is tried first always since
1414 it is faster to check.
1416 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1418 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1444 * Allow zero length channel messages inside the Channel Message
1445 Payload. Affected file lib/silccore/silcchannel.c.
1447 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1448 as header filenames.
1450 * Removed lib/silcclient/README and created HTML file
1451 lib/silcclient/silcclient_using.html, which is now included
1452 as part of Toolkit documentation.
1454 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1456 * Fixed CUMODE_CHANGE notify handling to change the mode of
1457 correct client. Affected file lib/silcclient/client_notify.c.
1459 * Make silc_rng_alloc fail if it cannot allocate the sha1
1460 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1462 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1464 * Fixed the file transfer's key agreement payload to include
1465 zero port also if the hostname is NULL because it could not
1468 Call file transfer monitor callback now also if error occurs
1469 during key agreement protocol.
1471 Changed the silc_client_file_send interface to return the
1472 SilcClientFileError instead of session id. The session ID
1473 is returned into pointer provided as argument.
1475 Check that the file exists locally before sending the
1476 file transfer request at all.
1478 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1480 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1481 error than can occur while key agreement protocol. Affected
1482 file lib/silcclient/silcapi.h.

1485 is changed and +k mode is set in the channel. Affected file
1486 irssi/src/silc/core/silc-channels.c.
1488 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1489 SILC_LOG_WARNING to give out Warning and not Error. Affected
1490 file lib/silcutil/silclog.c.
1492 * Fixed the channel message payload decryption in the function
1493 silc_channel_message_payload_decrypt to not modify the original
1494 buffer before it is verified that the message decrypted
1495 correctly. Otherwise, next time it is called with correct
1496 channel key it won't encrypt since the payload is corrupted.
1497 Affected file lib/silccore/silcchannel.c.
1499 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1509 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1511 * Fixed a bug in hash table internal routine for traversing
1512 the table with foreach callback. The current entry may
1513 become invalid in the callback but it was referenced after
1514 the callback returned.
1516 Do not allow auto rehashing of hash table during the
1517 silc_hash_table_foreach operation, for same reasons as it is
1518 not allowed for SilcHashTableList. Affected files are
1519 lib/silcutil/silchashtable.[ch].
1521 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1523 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1524 Win32 DLL. extern's in header files are now declared with
1527 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * Fixed private message handling. It used some old code that
1530 caused the client to crash. Affecte file is
1531 lib/silcclient/client_prvmsg.c.
1533 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1535 * Added function silc_client_add_channel,
1536 silc_client_replace_channel_id, and removed functions
1537 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1538 from client library.
1540 * Added cross reference of the joined channels to the
1541 SilcClientEntry, and changed the SilcChannelEntry's
1542 users list to SilcHashTable. The affected files are
1543 lib/silcclient/idlist.[ch].
1545 * Fixed a bug in hash table tarversing. While the hash table
1546 is traversed with SilcHashTableList the table must not be
1547 rehashed. It is now guaranteed that auto rehashable tables
1548 are not rehashed while tarversing the list. Also defined that
1549 silc_hash_table_rehash must not be called while tarversing
1550 the table. Added function silc_hash_table_list_reset that must
1551 be called after the tarversing is over. The affected files are
1552 lib/silcutil/silchashtable.[ch].
1554 * Changed all hash table traversing to call the new
1555 silc_hash_table_list_reset in server and in client library.
1557 * Added function silc_client_on_channel to return the
1558 SilcChannelUser entry if the specified client entry is joined
1559 on the specified channel. This is exported to application as
1560 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1562 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1564 * Fixed founder regaining problem with JOIN command on normal
1565 server. The notify for mode change must be sent always and
1566 not only if !cmd->pending. Affected file silcd/command.c.
1568 * Fixed the WHOWAS command's reply sending to support the
1569 lists correctly. Affected file silcd/command.c.
1571 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1573 * When sending JOIN command to router for processing the
1574 sender's old command identifier was not saved back to the
1575 sender's command context, fixed now. The affected file is
1578 * Create the key in JOIN command of the router did not return
1579 the channel key, added check for this. Affected file is
1582 * Fixed a channel ID update bug in JOIN command reply. Do
1583 not directly upgrade the ID but call the function
1584 silc_idlist_replace_channel_id if the ID was changed.
1585 Affected file silcd/command_reply.c.
1587 * Fixed memory leaks from command calling if it would fail.
1588 Affected file silcd/command.c.
1590 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Applied patches from cras:
1594 Memory leak fixes around libaries, irssi window resize fix,
1595 new silclist.h and silcdlist.h, all extern inline changed to
1598 * Removed dotconf from lib/dotconf, not needed anymore.
1600 * Removed TRQ from lib/trq, not needed anymore.
1602 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1603 with server connections. Later this will be configurable
1604 in config file after new config file is done. Affected file
1607 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1609 * Fixed a crash in server related to channel announcements.
1610 Affected file silcd/server.c.
1612 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed memory leaks in silc_server_create_new_channel*
1615 functions. Affected file silcd/server.c.
1617 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1618 which ID was changed. This way the router will send the
1619 user list for the channel again, and server won't be in
1620 desync in some rare circumstances. Affected file is
1621 silcd/packet_receive.c.
1623 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Check for NULL socket pointer in the function
1626 silc_server_packet_send_to_channel_real. Affected file
1627 silcd/packet_send.c.
1629 * Fixed the BAN notify handling to correctly remove ban
1630 list. Affected file silcd/packet_receive.c.
1632 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Fixed some header addition to Toolkit distribution in
1635 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1637 * Added lib/silcclient/client_ops_example.h as an template
1638 file for application programmers to quickly start using
1639 the SilcClientOperation functions in their application.
1640 Updated the lib/silcclient/README as well to tell about this
1641 nice file made available.
1643 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Call silc_server_remove_from_channels when removing client
1646 entry when NO_SUCH_CLIENT_ID was received. Affected file
1647 is silcd/command_reply.c.
1649 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1651 * Added server & router operator statistics updating. Affected
1652 file silcd/packet_receive.c and silcd/command.c.
1654 * Fixed the SERVER_SIGNOFF notify handling on normal server
1655 not to save the history information for clients. Same was
1656 fixed earlier in remove_clients_by_server function, but not
1657 here. Affected file silcd/packet_receive.c.
1659 * Raised the default connection-retry count from 4 to 7 in
1660 server. Affected file silcd/server.h.
1662 * Cancel any possible reconnect timeouts when we start the
1663 key exchange. Affected file silcd/server.c.
1665 * Do not reconnect on connection failure when SCONNECT was
1666 given. Affected files silcd/server.[ch].
1668 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1672 * Fixed the NICK command to always give the unformatted
1673 nickname to the one giving the NICK command. If unformatted
1674 nickname is cached already it will be formatted and the
1675 local entry will always get the unformatted nickname.
1676 Affected file lib/silcclient/idlist.c.
1678 * Fixed some double frees from client library commands.
1679 Affected file is lib/silcclient/command.c.
1681 * Fixed CUMODE command in server to assure that no one can
1682 change founder's mode than the founder itself, there was a
1683 little bug. Affected file silcd/command.c.
1685 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1687 * Removed the SilcClientCommandDestructor from the client
1688 libary, it is not needed anymore. Affected files are
1689 lib/silcclient/silcapi.h, command[_reply].[ch],
1690 client_notify, idlist.c.
1692 * Fixed GETKEY command to first resolve client, and then
1693 resolve the server only if the client was not found, instead
1694 of resolving both at the same time. Affected file is
1695 lib/silcclient/command.c.
1697 * Added silc_client_start_key_exchange_cb and lookup the
1698 remote hostname and IP address before starting the key
1699 exchange with server. The affected file is
1700 lib/silcclient/client.c.
1702 * The server's public key is now saved using the IP address
1703 of the server and not the servername for the filename.
1704 The hostname public key filename is checked as an fall back
1705 method if the IP address based filename is not found.
1707 Fixed the GETKEY command to save the fetched server key
1708 in correct filename.
1710 Print the remote server's hostname now when new key is
1711 received during connection process. Affected file is
1712 irssi/src/silc/core/client_ops.c.
1714 * Return always our own public key to the client if it asks
1715 for it with GETKEY command. Affected file silcd/command.c.
1717 * Removed the use_auto_addr variable from default config
1718 file since it was in wrong section. Affected file is
1721 * Fixed TOPIC_CHANGE notification to not route it when it
1722 was sent using silc_server_send_notify_to_channel function.
1723 Affected file silcd/command.c.
1725 * Fixed silc_server_send_notify_kicked to send the kicker's
1726 Client ID also, it was missing. Affected files are
1727 silcd/command.c, silcd/packet_send.[ch].
1729 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1731 * Do not save client history information in SERVER_SIGNOFF.
1732 Fixes the bug in normal server that it does not detect
1733 the client becoming valid after the server becomes back
1734 online. Affected file silcd/server_util.c.
1736 * Added `sock_error' field into the SilcSocketConnection
1737 context. When error occurs during socket operation (read
1738 or write) the error is saved. Added also new function
1739 silc_socket_get_error to return human readable socket error
1740 message. Affected files are lib/silcutil/silcsockconn.[ch],
1741 lib/silcutil/unix/silcunixsockconn.c, and
1742 lib/silcutil/win32/silcwin32sockconn.c.
1744 * The server now prints the socket error message in the
1745 signoff for client. Affected file silcd/server.c.
1747 * Fixed the `created' channel information sending from router
1748 to server in JOIN command. Checks now whether the channel
1749 really was created or not and set it according that.
1751 Fixed the JOIN command to use the client entry's current
1752 ID during the joining procedure instead of the one it sent
1753 in the command (it is checked though), since it can change
1754 between the packet processing and command processing, and
1755 would just case unnecessary pain in the client end. Affected
1756 file silcd/command.c.
1758 * Fixed a channel key payload sending to use correct channel
1759 ID when the server was forced to change the channel's ID by
1760 router. Router sent the key payload with the old Channel ID.
1761 Affected file silcd/packet_receive.c.
1763 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Call silc_server_save_channel_key only if the key payload
1766 was provided in the JOIN command's command reply. Affected
1767 file silcd/command_reply.c.
1769 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed silc_mp_sizeinbase to return the value correctly with
1772 MPI. Affected file lib/silcmath/mp_mpi.c.
1774 * Fixed the stop_server signal to correctly stop the scheduler
1775 and gracefully stop the server when SIGTERM or SIGINT signals
1776 are received. Affected file silcd/silcd.c.
1778 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1780 * Simple handling of TERM and HUP signals. Also added some log
1781 flushing call around. Affected file is
1784 * Fixed small bugs in silclog.c. Now buffering output will take
1785 effect after 10 seconds since startup: This will ensure that
1786 no important startup messages are lost. Also output redirection
1787 will preserve original format ([Date] [Type] message).
1788 Affected file is lib/silcutil/silclog.c.
1790 * Added two options to the config file, in the logging section:
1791 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1792 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1794 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1796 * Do not print the warning about log files not being initialized
1797 more than once to avoid excess logging. Affected file is
1798 lib/silcutil/silclog.c.
1800 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1801 the SIM copying in make install in Makefile.am.pre.
1803 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1805 * Rewritten silclog APIs. Globally interesting changes follows:
1806 silc_log_set_files() changed to silc_log_set_file().
1807 silc_log_set_callbacks() changed to silc_log_set_callback().
1808 ROBOdoc documented silclog header file.
1809 SilcLogCb now returns bool to wether inihibit the default
1810 handler or not (to keep the old behaviour return always TRUE).
1811 The new APIs should also fix the problem of the
1812 silcd_error.log file that was written in the current directory.
1815 Log files streams will remain opened after silc_log_set_file()
1816 call, means less CPU usage notably on high traffic servers.
1817 File streams are now full buffered, and flushed to the disk
1818 every 5 minutes, lesses HD activity and CPU usage.
1819 Messages can be redirected, allowing admins to configure
1820 one single logfile for all server messages.
1821 the silc_log_quick global variable to activate fast-logging.
1822 Affected files lib/silcutil/silclog.[ch]
1824 * Changed some code to conform new silclog APIs. Affected
1825 files are doc/example_silcd.conf.in, silcd/server.c
1826 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1829 * Fixed a memory leak that could occur in some situations.
1830 Affected file silcd/serverconfig.c.
1832 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1834 * Added the silc_client_del_client to remove the client from
1835 all channels as well. Affected file lib/silcclient/idlist.c.
1837 * Fixed the client library to correctly remove the client
1838 from all channels when the client entry is being destroyed.
1839 Affected file lib/silcclient/client_notify.c, command.c.
1841 * Added auto-nicking support to the client library. If the
1842 applicatio now sets client->nickname it will be sent to the
1843 server after connecting by the library. This way for example
1844 SILCNICK (or IRCNICK) environment variables will have effect
1845 and always change the nickname automatically to whatever
1846 it is wanted. Affected file lib/silcclient/client.[ch].
1848 * Renamed silc_server_command_bad_chars to the
1849 silc_server_name_bad_chars and moved it to the
1850 silcd/server_util.[ch]. Added also new function
1851 silc_server_name_modify_bad to return nickname that
1852 includes bad characters as new nickname without those
1853 bad characters. This check and modify is now used in
1854 silc_server_new_client when the username is initially set
1855 as nickname, so it must be checked to be valid nickname.
1856 Affected file silcd/packet_receive.c.
1858 * The nickname length is now taken from the packet for real
1859 and not trusted to strlen() since it clearly can return
1860 wrong length for nickname including bad characters. This
1861 also applies to channel names. Affected file silcd/command.c.
1863 * Removed the lib/silcsilm/modules directory. Modules are now
1864 compiled into the lib/silcsim. Fixed the copying of the
1865 modules to follow symbolic links in Makefile.am.pre.
1867 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1869 * Fixed silc_string_regexify list creation. Fixes bugs with
1870 BAN and INVITE commands in server. The affected file is
1871 lib/silcutil/unix/silcunixutil.c.
1873 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Removed the command destructor entirely from the server's
1876 command and command reply routines. It is not needed, and
1877 its usage was buggy and caused crashes. Affected files are
1878 silcd/command[_reply].[ch].
1880 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * Cancel protocol and NULL sock->protocol if timeout
1883 occurred during protocol. Affected file silcd/server.c.
1885 * Cancel protocol timeouts always before calling the final
1886 callback, to assure that after final callback is called
1887 no other state will be called for the protocol anymore.
1888 Affected file silcd/protocol.c.
1890 * Print error log if incoming connection configuration could
1891 not be found. Affected file silcd/server.c.
1893 * Fixed JOIN command to correctly save the founder mode
1894 to the client on normal SILC server, when the channel
1895 was created by the router. Affected file silcd/command.c.
1897 * Fixed LIST command (hopefully) to send correct reply
1898 packets. Affected file silcd/command.c.
1900 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * The silc_packet_receive_process now returns FALSE if the
1903 read data was invalid packet, and TRUE if it was ok.
1905 The server now checks that if unauthenticated connection
1906 sends data and its processing fails the server will close
1907 the connection since it could be a malicious flooder.
1909 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1911 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Make sure the warning about error opening a log file is
1914 printed only once and not everytime it fails (produces
1915 too much useless log). Affected file lib/silcutil/silclog.c.
1917 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1919 * Made the silc_server_daemonise() function more readable.
1920 Affected file silcd/server.c.
1922 * Pid file is now optional, the user may comment it out from
1923 the config file. Removed define SILC_SERVER_PID_FILE, we
1924 don't need a default any longer. Affected file
1925 configure.in.pre, lib/Makefile.am.pre.
1927 * Make some use of the pid file. The server now dies at startup
1928 if it detects a valid pid file on his path. The server would
1929 die anyway in this circumstance, because of the bind() failure.
1930 Affected file silcd/silcd.c.
1932 * No longer compiling lib/dotconf.
1934 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Fixed JOIN command parsing not to crash. Affected file
1937 lib/silcclient/command.c.
1939 * Fied the NICK_CHANGE notify to add the new client entry
1940 even it is resolved. This removes an <[unknown]> nick
1941 thingy bug in the client. Affected file is
1942 lib/silcclient/client_notify.c.
1944 * Do not try to allocate 0 bytes (efence does not like it)
1945 in lib/silccore/silccomand.c when encoding payload.
1947 * Do not take IRCNICK as nickname in Irssi SILC client since
1948 it is not possible to set nickname before hand connecting
1949 the server (TODO has an entry about adding auto-nicking
1952 * Changed the silc_server_command_pending to check whether
1953 there already exists an pending entry with the specified
1954 command, command identifier and pending callback. This is
1955 to fix IDENTIFY and WHOIS related crashes that may register
1956 multiple pending commands with same identifier. Affected
1957 file silcd/command.c.
1959 * Fixed the server to reconnect to the router even if it
1960 was already reconnecting and EOF was received. This to
1961 fix a possibility that the server wouldn't ever try to
1962 auto-reconnect to the router. Affected file silcd/server.c.
1964 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Fixed the server's password authentication to use the
1967 length of the locally saved password, and not the one
1968 sent in the packet. Affected file silcd/protocol.c.
1970 * Fixed same password authentication problem in the
1971 Authentication Payload handling routines in
1972 lib/silccore/silcauth.c.
1974 * Yet another password authentication problem fixed with
1975 channel password handling in silcd/command.c.
1977 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * If first character of string in silc_parse_userfqdn is '@'
1980 then do not parse it. Affected file is
1981 lib/silcutil/silcutil.c.
1983 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Fixed minor bug in IDENTIFY command reply sending, which
1986 caused various weird problems during JOIN when it was
1987 resolving names for users. Affected file silcd/command.c.
1989 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Fixed the IDENTIFY command reply sending to chech better valid
1992 clients. It was possible to send incomplete list of replies.
1993 Affected file silcd/command.c.
1995 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Added silc_client_command[s]_[un]register functions now to
1998 dynamically register the commands in client library. Removed
1999 the static table of commands. This allows the client library
2000 to call commands without causing the application to know about
2001 what commands library has called.
2003 Removed the INFO command reply kludge to detect when the command
2004 was called by library. Now library use its own command reply
2005 function for INFO command.
2007 Added function silc_client_command_call to call a command.
2008 Application can use it to call command, not access the structure
2011 Now all commands that are sent by the client library (not
2012 explicitly sent by application) use own command reply functions.
2014 Affected files around lib/silcclient/ and in
2015 irssi/src/silc/core/.
2017 * Fixed the WHOIS command reply sending to chech better valid
2018 clients. It was possible to send incomplete list of replies.
2020 Fixed the WHOIS and IDENTIFY to send the request to router
2021 if normal server did not do it and did not find any results.
2023 Affected file silcd/command.c.
2025 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Moved the internal data from SilcClient context into its
2028 own file, not accesible to application. Affected files
2029 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2030 and other files in client library.
2032 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Added doc/examples installation target in Makefile.am.pre.
2037 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2040 commands the found client entry will be removed from the
2041 cache, after notifying application about the error. Affected
2042 file lib/silcclient/command_reply.c.
2044 * Changed the /MSG to check for exact nickname user gave, and
2045 not let `nick' match `nick@host' if it is only one found. Now,
2046 user must type the exact nickname (like nick@host2) even if
2047 there are no more than one same nicks found. This is to avoid
2048 a possibility of sending nickname to wrong nickname since
2049 `nick' could match `nick@host'. Affected file is
2050 irssi/src/core/silc-servers.c.
2052 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Do not print "you are now server operator" or similar when
2055 giving /away command. Affected files are
2056 irssi/src/silc/core/client_ops.c, silc-servers.h.
2058 * Made the silc_server_command_pending_error_check to send
2059 the same command reply payload it received back to the
2060 original sender of the command. This way all arguments
2061 that was received by the server will be received by the
2062 client too. Affected file silcd/command.c.
2064 * Added the silc_idcache_add to return the created cache entry
2065 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2067 * Add global clients to expire if they are not on any channel.
2068 This is because normal server will never know if they signoff
2069 if they are not on any channel. The cache expiry will take
2070 case of these entries. This is done by normal servers only.
2071 The affected files are silcd/command_reply.c,
2072 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2074 * If server receives invalid ID notification for WHOIS or
2075 IDENTIFY and the ID exists in the lists, it is removed.
2076 Affected file silcd/command_reply.c.
2078 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2079 in client then client entry that it matches is searched and
2080 the nickname is printed on the screen for user. Affected
2081 file irssi/src/silc/core/client_ops.c.
2083 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Use cache entry expire time in the LIST command reply to
2086 purge old entries from the cache after the LIST command
2087 reply has been received. This way we don't have non-existent
2088 entries in the cache for too long. Affected file is
2089 silcd/command_reply.c.
2091 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * If we are normal server, and we've not resolved client info
2094 in WHOIS or IDENTIFY from router, and it is global client,
2095 we'll check whether it is on some channel. If it is not
2096 then we cannot be sure about its validity and will resolve it
2097 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2098 file silcd/command.c.
2100 * Search channel by name (if possible) rather than by ID
2101 in IDENTIFY command's command reply. Affected file is
2102 silcd/command_reply.c.
2104 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2107 Updated specs and implemented it. Affected file silcd/command.c,
2108 silcd/packet_send.c and silcd/packet_receive.c.
2110 * Implemented the <founder auth> payload handling in the JOIN
2111 command. If provided all conditions for channel joining
2112 except requirement to provide correct passphrase can be
2113 overrided by the channel founder. Updated the protocol specs.
2114 Affected file silcd/command.c.
2116 Added support for founder auth in JOIN command in client
2117 library. Fixed the parsing of the JOIN command now to support
2118 all options as they should be. The affected file is
2119 lib/silcclient/command.c.
2121 * Optimized the WHOIS and IDENTIFY commands to send the request
2122 to router only if it includes nicknames or other names. If
2123 they include only IDs then check the local cache first before
2124 routing. Affected file is silcd/command.c.
2126 * Added channels topic announcements. Affected file is
2127 silcd/packet_receive.c and silcd/server.c.
2129 * Fixed the silc_server_send_notify_topic_set to really destine
2130 the packet to channel. Affected file silcd/packet_send.c.
2132 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2133 library. Affected file lib/silcclient/client_notify.c.
2135 * Added UMODE announcements. Affected file silcd/server.c.
2137 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Memory leak fixes in:

2146 lib/silccore/silccommand.c
2147 lib/silccore/silcidcache.c
2152 * ROBOdoc documented the lib/silcske/groups.h file and a
2153 bit changed the interface for better.
2155 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2157 * Update the client entry context in the ID cache after
2158 nick change. Affected file lib/silcclient/command.c.
2159 Fixes the CUMODE command when regaining founder privileges,
2160 and a little WHOIS problem.
2162 * Fixed silc_net_gethostbyname to correctly call the
2163 inet_ntop. Affected file lib/silcutil/silcnet.c.
2165 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2167 * Added IPv6 support checking to the configure.in.pre, added
2168 also --enable-ipv6 option to override the check. Affected
2169 file configure.in.pre.
2171 * The silc_thread_create now calls the start function
2172 directly if threads support is not compiled in. Removes
2173 ugly #ifdef's from generic code. Affected files are
2174 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2176 * Added silc_net_gethostby[name/addr]_async to asynchronously
2177 resolve. Affected files are lib/silcutil/silcnet.[ch].
2179 * Added support for rendering IPv6 based server, client and
2180 channel IDs. Affected file lib/silcutil/silcutil.c.
2182 * Added support for creating IPv6 based server IDs. Affected
2183 file is silcd/serverid.c.
2185 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2187 * Added silc_net_gethostby[addr/name] into the
2188 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2189 routines. Added silc_net_is_ip[4/6]. Affected file is
2190 lib/silcutil/unix/silcunixnet.c. All routines that take
2191 address as argument now supports both IPv4 and IPv6 addresses.
2193 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2195 * Fixed LIST command reply sending in server. Affected file
2198 * Server now sends the kicker's client ID in the KICK notify
2199 to the kicked client. Affected file silcd/command.c.
2201 * The client library now parses the kickers client ID and
2202 UI displays it. Affected files lib/silcclient/client_notify.c
2203 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2205 * Made all payload parsing function prototypes consistent.
2206 They all take now const unsigned char * and uint32 pair as
2207 the payload data instead of SilcBuffer. Changes all around
2208 the source tree. Other unsigned char* -> const unsigned char*
2209 changes around the tree as well.
2211 * Optimized SFTP client and server packet sending not to
2212 allocate new buffer for each packet but to recycle the
2213 first allocated buffer. Affected files are
2214 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2216 * Optimized the SFTP client to use SilcList instead of
2217 SilcDList for requests, because it is faster. Affected file
2218 is lib/silcsftp/sftp_client.c.
2220 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2221 into lib/silccore/silcid.[ch].
2223 Renamed silcpayload.[ch] into silcargument.[ch].
2225 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * If client entry is deleted with active key agreement
2228 session, abort the session.
2230 The silc_client_abort_key_agreement now calls the completion
2231 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2233 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2236 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * Don't use __restrict in older GCC's. Affected file is
2239 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2241 * silc_net_localhost now attempts to reverse lookup the
2242 IP/hostname. Affected file lib/silcutil/silcnet.c.
2244 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2245 command. It can be used to gain founder privileges at
2246 the same time when joining the channel.
2248 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2249 kicker's client ID as well. Updated protocol specs.
2251 Defined that the server must send SILC_COMMAND_IDENTIFY
2252 command reply with error status to client who sent
2253 private message with invalid client ID.
2255 Updated the protocol specification.
2257 * Added silc_server_send_command_reply to send any
2258 command reply. Affected file silcd/packet_send.[ch].
2260 * Added silc_id_payload_encode_data to encode ID payload
2261 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2263 * The server now send IDENTIFY command reply with error
2264 status if client ID in private message is invalid. Affected
2265 file silcd/packet_receive.c.
2267 * Save the server key file with server's IP address in
2268 the filename instead of hostname. The affected file is
2269 irssi/src/silc/core/client_ops.c.
2271 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2276 * Added libtool support for compiling shared objects in
2277 lib/silcsim. Affected file configure.in.pre and
2278 lib/silcsim/Makefile.am. Original patch by cras.
2280 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Pid file configuration, and server's config file fixes
2283 patch by toma. Updated CREDITS file.
2285 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Fixed silc_client_channel_message to not try to decrypt
2288 the message twice if it resolved the destination client
2289 information. This could cause of dropping one channel
2290 message. Affected file lib/silcclient/client_channel.c.
2292 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2295 lib/silcclient/client.c. This function is used when the SILC
2296 Client is run under some other scheduler, or event loop or
2297 main loop. On GUI applications, for example this may be
2298 desired to used to run the client under the GUI application's
2299 main loop. Typically the GUI application would register an
2300 idle task that calls this function multiple times in a second
2301 to quickly process the SILC specific data.
2303 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2305 * Fixed silc_server_drop() for dropping the supplementary
2306 groups as well, this could cause a security hole on some
2309 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2314 * Write PID file after dropping privileges. Added -F option
2315 to run server on foreground. A patch by debolaz.
2316 Affected files silcd/server.c, silcd/silcd.c.
2318 * Fixed MOTD to return the MOTD file server name. Affected
2319 file silcd/command.c.
2321 * Added INFO command reply handling to the Irssi SILC Client.
2322 Affected file irssi/src/silc/core/client_ops.c.
2324 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed the silc_idcache_list_* routines to really support
2327 the dynamic list. Fixes a crash. Affected file is
2328 lib/silccore/silcidcache.c.
2330 * Fixed the LIST command reply to really call LIST command's
2331 pending callbacks. Affected file silcd/command_reply.c.
2333 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Update conn->local_entry->nickname after giving NICK
2336 command. Affected file lib/silcclient/command.c.
2338 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2340 * Added the [pid] option to the silcd configuration file
2342 Affected files: serverconfig.[ch] and silcd.c
2344 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2346 * Save fingerprint in WHOIS command reply in server.
2347 Affected file silcd/command_reply.c.
2349 * Fixed NICK commands pending callback registration.
2350 Affected file lib/silcclient/command.c.
2352 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Use ++server->cmd_ident when sending commands in server,
2355 instead of random number. Affected file silcd/command.c.
2357 * Fixed GETKEY command reply to call actually GETKEY pending
2358 command callbacks. Affected file silcd/command_reply.c.
2360 * A bit stricter check for nicknames. Check for same nickname
2361 in NICK command also. Affected file silcd/command.c.
2363 * Do not call INFO command everytime client ID changes, only
2364 during first connecting. Affected file lib/silcclient/client.c.
2366 * Set the new nickname only after successful command reply for
2367 NICK command is returned by server. Affected file
2368 lib/silcclient/command.c.
2370 * Remove nicknames from nicklist during server_signoff notify.
2371 Should fix /NAMES bit more. The affected file is
2372 irssi/src/silc/core/silc-channels.c.
2374 * Added `fingerprint' field to the SilcIDListData in the
2375 silcd/idlist.h to hold the fingerprint of the client's
2378 Send the fingerprint of the client's public key in WHOIS
2381 Affected files silcd/command.c, and silcd/idlist.[ch].
2383 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2384 create fingerprint from given data.
2386 * Show the fingerprint of the client's public key in WHOIS.
2387 Affected files irssi/src/module-formats.[ch] and
2388 irssi/src/silc/core/client_ops.c.
2390 * Format the multiple same nicknames also during JOIN and
2391 NICK_CHANGE notifys. Affected file is
2392 lib/silcclient/client_notify.c.
2394 * Do not print error on screen for invalid private message
2395 payload since it can come if someone is sending private
2396 messages with wrong key. Affected file
2397 lib/silccore/silcprivate.c.
2399 * Fixed multiple concurrent /PING crash. Affected file
2400 lib/silcclient/command.c.
2402 * Changed the wrong ID encoding. All IP addresses must be
2403 in MSB first order in encoded format. They were encoded
2404 wrong and was in LSB format. Affected files are
2405 silcd/serverid.c, lib/silcutil/silcutil.c.
2407 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2409 * Call the `connect' client operation through the scheduler
2410 in case of error. Affected file lib/silcclient/client.c.
2412 * Call the `failure' client operation even if the error
2413 occurred locally during a protocol. Affected file is
2414 lib/silcclient/protocol.c.
2416 * Added support of sending LIST command to router from normal
2417 server. This way normal server can get list of all channels
2418 in the network too. Fixed the channel list sending in the
2419 server too. Affected files are silcd/command.c, and
2420 silcd/command_reply.[ch].
2422 * Added silc_server_update_channels_by_server and
2423 silc_server_remove_channels_by_server. They are used during
2424 disconnection of primary router and in backup router protocol.
2425 Affected file silcd/server_util.[ch], silcd/server.c and
2426 silcd/server_backup.c.
2428 * Fixed channel adding to global list in IDENTIFY command
2429 reply in server. Affected file silcd/command_reply.c.
2431 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * If the incoming packet type is REKEY or REKEY_DONE process
2434 that packet always synchronously. Fixes yet another MAC
2435 failed error on slow (dialup) connections. Affected file
2436 lib/silcclient/client.c and silcd/server.c.
2438 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Call check_version SKE callback for initiator too. Affected
2441 file lib/silcske/silcske.c.
2443 * Implemented fix for security hole found in the SKE that was
2444 fixed in the specification few days back; the initiator's
2445 public key is now added to the HASH value computation.
2446 Added backwards support for the old way of doing it too, for
2447 old clients and old servers. Affected file is
2448 lib/silcske/silcske.c.
2450 * Enabled mutual authentication by default in SKE. If initiator
2451 is not providing mutual authentication the responder will
2452 force it. This will provide the proof of posession of the
2453 private key for responder. The affected files are
2454 lib/silcclient/protocol.c and silcd/protocol.c.
2456 * Do not cache anymore the server's public key during SKE.
2457 We do mutual authentication so the proof of posession of
2458 private key is done, and if the server is authenticated in
2459 conn auth protocol with public key we must have the public
2460 key already. Affected file silcd/protocol.c.
2462 * Added new global debug variable: silc_debug_hexdump. If
2463 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2464 file lib/silcutil/silclog.[ch].
2466 * Fixed compilation warning due to char * -> const char *.
2467 Affected files lib/silcutil/silcnet.h, and
2468 lib/silccore/silcauth.[ch].
2470 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Fixed CMODE command when new channel key was created. If
2473 the creation failed the old key was removed. Next time giving
2474 same command would crash the server since the old key was
2475 freed already. Affected file silcd/command.c.
2477 * Fixed the silc_server_announce_get_channels to not crash
2478 on reconnect. Affected file silcd/server.c.
2480 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Added silc_log_set_debug_string function to set a regex
2483 string to match for debug output. Only the function names,
2484 or filenames matching the given debug string is actually
2485 printed. This way it is possible to filter out those debug
2486 strings that user is not interested in.
2488 Fixed a bug in silc_string_regexify.
2490 Affected files lib/silcutil/silclog.[ch], and
2491 lib/silcutil/unix/silcunixutil.c.
2493 * Changed the -d options in both server and Irssi SILC client
2494 to take the debug string as argument. Affected files
2495 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2497 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Added silc_hash_babbleprint to create a Bubble Babble
2500 Encoded fingerprint. The encoding is developed by Antti
2501 Huima (draft-huima-babble-01.txt), and it creates human
2502 readable strings out of binary data. Affected file
2503 lib/silccrypt/silchash.[ch].
2505 * Print the babble print now in addition of fingerprint as well
2506 in Irssi SILC client. Affected files are
2507 irssi/src/fe-common/silc/module-formats.[ch],
2508 irssi/src/fe-common/silc/core/client_ops.c.
2510 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Fixed a security problem found in SKE. The initiator's
2513 public key too is now added to the HASH hash value creation
2514 which is signed by the responder to create the SIGN value.
2515 This will prevent anyone in the middle to lie to the responder
2516 about the initiator's public key. If this is done now, the
2517 man in the middle will get caught. Updated the protocol
2520 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Better installation directory handling. Configure module
2523 paths and other paths automatically to example_silc* files
2524 in doc/. A patch by toma.
2526 * Fixed compiler warning from MPI library, and from SILC RNG.
2529 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2530 It can be configured with ./configure. A patch by toma.
2532 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Find correct make to use in prepare-clean. A patch by
2535 toma. Affected file prepare-clean.
2537 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2539 * Added irssi variables use_auto_addr, auto_bind_ip,
2540 auto_bind_port and auto_public_ip.
2542 * Changed the interface for silc_client_send_key_agreement
2543 in lib/silcclient/silcapi.h
2547 irssi/src/silc/core/silc-core.c
2549 lib/silcclient/silcapi.h
2550 irssi/src/silc/core/silc-channels.c
2551 lib/silcclient/client_keyagr.c
2554 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Added silc_pkcs_public_key_compare to compare two
2557 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2559 * Check that the client who set the founder mode on the
2560 channel is the same client that is giving the founder
2561 mode to itself. It is done by comparing the saved public
2562 key (it is saved even in the authentication is passphrase).
2563 Affected file silcd/command.c.
2565 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Do not process packet for disconnected socket connection.
2568 Affected file lib/silccore/silcpacket.c.
2570 * Process the DISCONNECT packet through scheduler in the
2571 client library. Affected file lib/silcclient/client.c.
2573 * Fixed the silc_client_packet_parse to not to increase
2574 the packet sequence number if the conn->sock and the
2575 current socket connection is not same. This can happen
2576 for example during key agreement when the conn includes
2577 multiple socket connections (listeners). Affected file
2578 lib/silcclient/client.c.
2580 * The sender of the file transfer request now provides also
2581 the pointer (listener) for the key exchange protocol. If
2582 the listener cannot be created then it sends empty key
2583 agreement and lets the receiver provide the listener.
2585 Added `local_ip' and `local_port' arguments to the
2586 silc_client_file_send. If they are provided they are used,
2587 if not then it will attempt to find local IP address, if
2588 not found or bind fails then the remote client will provide
2591 Affected files are lib/silcclient/client_ftp.c and
2592 lib/silcclient/silcapi.h.
2594 * Extended the FILE SEND command to support defining the
2595 local IP and port for key exchange listener. They are
2596 optional. Affected file irssi/src/silc/core/silc-servers.c.
2598 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Defined to WHOIS command reply the sending of fingerprint
2601 of the client's public key (if the proof of posession of the
2602 corresponding private key is verified by the server).
2603 Updated to the protocol specification.
2605 * Added support of receiving the client's public key's
2606 fingerprint in command reply in client library. Affected
2607 file is lib/silcclient/command_reply.c, and
2608 lib/silcclient/idlist.[ch].
2610 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Do not send over 128 chars long nickname to the server
2613 in NICK command. Affected file lib/silcclient/command.c.

2667 preserve the WHOWAS info for the client. Affected file
2668 silcd/server_util.c.
2670 * Fixed SERVER_SIGNOFF notify handling in the server. The
2671 server is now able to process incoming SERVER_SIGNOFF notify
2672 for a server that it doesn't even know about. It will remove
2673 the clients provided in the notify. Affected file
2674 silcd/packet_receive.c.
2676 * Check for partial packet in data queue after every packet that
2677 was found from the queue. Return and wait for more data if
2678 there is partial data in queue. Affected file is

2698 * Wrote a help file for FILE command.
2700 * Added silc_rng_global_get_byte_fast to get not-so-secure
2701 random data as fast as possible. Random data is read from
2702 /dev/urandom if available and from the SILC RNG if not
2703 available. It is used in padding generation. Affected file
2704 lib/silccrypt/silcrng.[ch].
2706 * All packets in client library are now processed synchronously.
2707 Optimized packet processing a lot. Affected file
2708 lib/silcclient/client.c.

2719 * Assure that silc_client_notify_by_server_resolve does not
2720 resolve the client information multiple times. If it cannot
2721 be found by the first it cannot be found at all. Affected
2722 file lib/silcclient/client_notify.c.
2724 * Fixed WHOWAS command reply calling. Affected file
2725 lib/silcclient/command_reply.c.
2727 * Removed all references to silc_idlist_get_client from the
2728 Irssi SILC client since that call is internal call used by
2729 the library. The Irssi SILC client will use now client
2730 retrieval functions found in silcapi.h.
2732 * Fixed a bug in resolving nickname info before sending
2733 private message. It used freed memory. Affected file
2734 irssi/src/silc/core/silc-servers.c.

2755 * Added silc_net_localip to return local host's IP address.
2756 Affected file lib/silcutil/silcnet.[ch].
2758 * If key exchange or rekey protocol is active for a connection
2759 parse all packets syncronously since there might be packets
2760 in packet queue that we are not able to process without first
2761 processing packets before them. Affected file silcd/server,
2762 lib/silcclient/client.c.
2764 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2765 whether library should continue processing the packet.

2812 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2813 is incomplete and is being resolved, it won't be resolved
2816 Make sure also that USERS command reply does not resolve
2817 twice information. Affected file is
2818 lib/silcclient/command_reply.c.
2820 Make sure that silc_client_get_clients_by_list does not
2821 resolve twice same information.
2823 * Check for valid client->id in the silc_server_free_client_data.
2824 Affected file silcd/server.c.
2826 * Fixed /GETKEY nick@server not to crash if the server entry
2827 is not found. Affected file lib/silcclient/command.c.
2829 * Fixed the silc_server_check_cmode_rights to check the
2830 requested modes correctly. Affected file silcd/command.c.

2837 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Call the silc_server_udpate_servers_by_server in the
2840 primary router that comes back online in the backup resuming
2841 protocol. Otherwise it routes packets wrong. Affected file
2842 silcd/server_util.[ch], silcd/server_backup.c.
2844 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2847 lib/silcutil/silcbuffmt.[ch].
2849 * Redefined the SILC packet header to include the padding
2850 length. Affected file lib/silccore/silcpacket.[ch].
2852 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2853 length for maximum padding up to 128 bytes). Affected
2854 file lib/silccore/silcpacket.h.
2856 * Removed all backwards support for old 0.5.x MAC thingies.
2857 The SILC packet header change makes it impossible to be
2858 backwards compatible.
2860 * Send the ENDING packet with timeout in the backup resuming
2861 protocol. This is to assure that all routers has connected
2862 to the primary router. Affected file silcd/server_backup.c.
2864 * Changed the RNG to take the first IV from random data. It
2865 used to take it from zero actually. Changed the RNG also
2866 to use /dev/urandom during session. /dev/random is used
2867 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2869 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Changed the SILC packet header to have the first two bytes
2872 (the packet length) encrypted. Affected files aroung the
2873 code tree, lib/silccore/silcpacket.[ch]. Removed the
2874 SilcPacketCheckDecrypt callback. It is not needed anymore
2875 since the silc_packet_receive_process will determine now
2876 whether the packet is normal or special.
2878 * Implemented the unidirectional MAC keys. Affected files
2879 lib/silcske/silcske.c, silcd/protocol.c and
2880 lib/silcclient/protocol.c.
2882 * Implemented the packet sequence number to the MAC computation.
2883 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2884 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2885 lib/silcclient/protocol.c.
2887 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Allow backup router to announce servers. All servers
2890 announced by backup router are added to the global list
2891 automatically. Update hte server's socket to our primary
2892 router also when backup router announces a server.
2893 Affected file silcd/packet_receive.c.
2895 * Do not update the client->router in the function
2896 silc_server_udpate_clients_by_server if the client is on
2897 global list. We might fail to find any specific server
2898 for locally connected clients and local cell clients. They
2899 should still use the `from' and not `to' as client->router.
2900 This fixes backup router resuming protocol. Affected file
2901 silcd/server_util.c.
2903 * Decrease channel statistics count only if the channel
2904 deletion worked. Affected files are silcd/server.c and
2905 silcd/server_util.c.
2907 * Added silc_server_update_servers_by_server to update origin
2908 of all server entries. Used during backup router protocol.
2909 Affected files silcd/server_util.[ch], silcd/server.c. and
2910 silcd/backup_router.c.
2912 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2913 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2914 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2915 lib/silccrypt/silchmac.c.
2917 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2919 * Assure that router cannot reroute the same channel message
2920 to the sender. Affected file silcd/packet_receive.c.
2922 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2924 * Made better checks that the channel message is not sent
2925 to the router it came from. Affected file is
2926 silcd/packet_send.c. Fixed memory leak too.
2928 * Announce informations for incoming router connection, but
2929 only after checking if it is replaced by backup router.
2930 Affected file silcd/packet_receive.c.
2932 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Fixed the backup resuming protocol to work in multiple
2935 router environment. Affected file silcd/server_backup.c.
2937 * Route packet only to one router in the function
2938 silc_server_packet_send_to_channel. Affected file is
2939 silcd/packet_send.c.
2941 * Fixed silc_server_send_notify_dest to set the broadcast
2942 flag. Fixed the silc_server_send_notify_topic to actually
2943 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2944 Affected file silcd/packet_send.c.
2946 * Changed the SFTP Filesystem interface. Changed the
2947 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2948 the filesystem operation function. The SilcSFTPFilesystem
2949 is now a context that is allocated by all filesystem allocation
2950 functions and it already includes the operations structure
2951 and filesystem specific context. It is given as argument
2952 now to the silc_sftp_server_start. This made the interface
2953 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2954 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2956 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Changed the backup router adding and getting interfaces
2959 in the server. The router that will be replaced by the
2960 specified backup router is now sent as argument. Affected
2961 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2964 * Added silc_net_addr2bin_ne to return the binary form of
2965 the IP address in network byte order. Affected files
2966 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2968 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Check for existing server ID in silc_server_new_server
2971 and in silc_server_connect_to_router_final and remove the
2972 old entry if it exists. Affected file silcd/packet_receive.c,
2975 * Send the channel message always to only one router, either
2976 in upstream or downstream. Affected file is
2977 silcd/packet_send.c.
2979 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Wrote the definition of the backup resuming protocol to the
2982 protocol specification.
2984 * Removed one redundant channel key generation from normal
2985 server during joining procedure. Removed one redundant
2986 channel key sending from server to router during joining
2987 procedure. Affected file silcd/command.c.
2989 * Made minor bugfixes to the backup router resuming protocol.
2990 Affected file silcd/server_backup.c, server.c.
2992 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Added --disable-asm configuration option. Affected files
2995 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2998 * Implemented the backup resuming protocol that is used to
2999 resume the primary router position in the cell after the
3000 primary router comes back online. Affected files
3001 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3002 and silcd/server_util.[ch].
3004 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Sleep two (2) seconds after sending QUIT command to server.
3007 Affected file lib/silcclient/command.c.
3009 * Assure that if outgoing data buffer is pending do not force
3010 send any data. Affected file silcd/packet_send.c.
3012 * Assure that if outgoing data buffer is pending do not force
3013 send any data. Affected file lib/silcclient/client.c.
3015 * Implemented the backup router support when the primary router
3016 goes down. The servers and routers can now use the backup
3017 router as new primary router without loosing connectivity.
3019 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3022 in the server to indicate disabled entry. All data read
3023 from the connection will be ignored and no data is sent
3024 for entry that is disabled. Affected files are
3025 silcd/idlist.h, silcd/server.c.
3027 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Created SFTP client and server test programs in the
3030 lib/silcsftp/tests directory.
3032 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Implemented memory filesystem (virtual filesystem) for
3035 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3038 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Implemented the SFTP (SSH File Transfer Protocol) to the
3041 lib/silcsftp. It includes SFTP client and SFTP server
3044 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3046 * Moved lib/silccore/silcprotocol.[ch] to the
3047 lib/silcutil library.
3049 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3050 take variable argument list pointer as argument. Affected
3051 file lib/silcutil/silcbuffmt.[ch].
3053 * Added silc_buffer_set function that is used to set data
3054 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3055 Affected file lib/silcutil/silcbuffer.h.
3057 * Changed various routines in the core library to use the new
3058 silc_buffer_set instead of allocating new buffer only for
3061 * Added 64-bit value formatting and unformatting support to the
3062 silc_buffer_[un]format routines. Affected file is
3063 lib/silcutil/silcbuffmt.[ch].
3065 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3066 to includes/bitmove.h.
3068 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Fixed channel user mode saving in client library. Affected
3071 file lib/silcclient/command[_reply].c.
3073 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Defined the file transfer to the SILC Protocol. Added
3076 new packet type SILC_PACKET_FTP and defined File Transfer
3077 Payload. The mandatory file transfer protocol is SFTP
3078 (SSH File Transfer Protocol). Affected file in addition
3079 of the internet draft is lib/silccore/silcpacket.h.
3081 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3082 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3083 is used as part of backup router protocol when the primary
3084 router of the cell is back online and wishes to resume
3085 the position as primary router.
3087 * Redefined the MAC generation keys in the protocol. The
3088 same key is not used anymore in both direction. Both
3089 direction will now use different keys for sending and
3090 receiving. This fixes a potential security flaw. This
3091 change causes incompatibilities in the protocol.
3093 * Redefined also the MAC computation from the packet.
3094 An packet sequence number is now added to the MAC
3095 computation. This prevents possible replay attacks against
3096 the protocol. This change too causes incompatibilities
3099 Added `sequence' field to the SilcPacketContext to hold
3100 the current sequence number for the packet.
3102 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Added `created' field to the SilcIDListData in the file
3105 silcd/idlist.h to indicate the time when the entry was
3108 * Added `created' field to the SilcChannelEntry too. Affected
3109 file silcd/idlist.h.
3111 * Added `creation_time' aguments to all the announcement functions
3112 in the server. If it is provided then only the entries that
3113 was created after the provided time frame are actually
3114 announced. Affected file silcd/server.[ch].
3116 * The protocol says that the Channel ID's IP address must be
3117 based on the router's IP address. Added check for this in
3118 the silc_server_new_channel when processing incoming New Channel
3119 Payload. Affected file silcd/packet_receive.c.
3121 * Print out the correct version with --version in SILC client.
3122 Affected file irssi/src/silc/core/silc-core.c.
3124 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Fixed WHOWAS command to check for completnes of the client
3127 entry always, not just when the command is coming from client.
3128 Affected file silcd/command.c.
3130 * Added new function silc_server_packet_queue_purge to purge the
3131 outgoing data queue to the network. After the function returns
3132 it is guaranteed that the outgoing packet queue is empty.
3133 Affected file silcd/packet_send.[ch].
3135 * Purge the outgoing packet queue in the rekey protocol's final
3136 callback to assure that all rekey packets go to the network
3137 before quitting the protocol. Affected file silcd/server.c.
3139 * Added silc_client_packet_queue_parse as similar function as
3140 in server to the client library. The affected file is
3141 lib/silcclient/client.c.
3143 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Splitted silcd/server.c and created silcd/server_util.[ch]
3146 for utility functions.
3148 * Added new socket flag SILC_SF_DISABLED to indicate that the
3149 connection is open but nothing can be sent to or received from
3150 the connection. Affected file lib/silcutil/silsockconn.[ch].
3151 The checking for disabled socket is checked in the low level
3152 silc_socket_write and silc_socket_read functions.
3154 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Allow only nicknames and channel names that fits into the
3157 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3159 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * When processing JOIN command reply in server check that if
3162 the channel exists in our global list we'll move it the local
3163 list. Affected file silcd/command_reply.c.
3165 * Fixed the check whether client is joined on the channel already
3166 in JOIN command. Affected file lib/silcclient/command.c.
3168 * Fixed the JOIN command reply to check whether the channel
3169 already exists. Affected file lib/silcclient/command_reply.c.
3171 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Added silc_ske_status_string to map the SKE error numbers
3174 to readable strings. The affected files are
3175 lib/silcske/silcske[_status].[ch].
3177 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Do not show the private channels on the WHOIS channel list
3180 as it is not allowed by the protocol. The affected file is
3183 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Assure that the packet length digged from the actual packet
3186 is something sensible in the silc_packet_decrypt_rest_special
3187 in lib/silccrypt/silcpacket.c.
3189 * Free and NULL the allocated pointer in silc_hmac_alloc if
3190 the HMAC allocation fails. The affected file is
3191 lib/silccrypt/silchmac.c.
3193 * Print the selected security properties to the log files in
3194 the server. Affected file silcd/protocol.c.
3196 * Add SKE's reference counter even if calling the completion
3197 callback manually. Otherwise it goes negative, although it
3198 does not cause any problems. The affected file is
3199 lib/silcske/silcske.c.
3201 * Remove the client entry with short timeout after giving the
3202 KILL command. Affected file lib/silcclient/command.c.
3204 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3205 case all found clients are already disconnected (WHOWAS would
3206 found them) in the server. Affected file silcd/command.c.
3208 * Update the last_receive (time of last data received) to be
3209 updated only when received private or channel message so that
3210 the idle time showed in WHOIS makes more sense.
3212 * Added boolean field `valid' in to the SilcClientEntry in the
3213 client library to indicate whether the entry is valid or not.
3214 This fixes the nickname change bug on channel when changing
3215 the nickname to be same than the old (like nick to Nick) the
3216 nickname formatter doesn't set the new nick anymore to Nick@host.
3217 Affected file lib/silcclient/idlist.[ch].
3219 * Now actually fixed the nickname changing on disconnection.
3220 Added new function silc_change_nick to the Irssi SILC Client.
3221 Affected file irssi/src/silc/core/client_ops.c,
3222 irssi/src/silc/core/silc-nicklist.[ch].
3224 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Check that the public key exists in the GETKEY command before
3227 trying to encode it. Affected file silcd/command.c.
3229 * Print some notifications on received public keys with GETKEY
3230 command in the Irssi SILC Client. Affected files are
3231 irssi/src/fe-common/silc/module-formats.[ch],
3232 irssi/src/silc/core/client_ops.c.
3234 * Use IDENTIFY command to resolve the server information in the
3235 GETKEY command instead of INFO command. Affected file
3236 lib/silcclient/command.c.
3238 * All command reply functions in the client library now calls
3239 the pending command reply callbacks even if an error has
3240 occurred. The server has done this a long time and now it was
3241 time to move the client library to this as well. Now all
3242 errors can be delivered back to the pending command reply
3243 callbacks if necessary. Affected files are
3244 lib/silcclient/command[_reply].[ch].
3246 * Change the nickname on disconnection back to the username
3247 because in reconnect the server will enforce it to it anyway.
3248 Affected file irssi/src/silc/core/silc-servers.c.
3250 * Fixed a config file parsing bug in the Irssi SILC client.
3251 Affected file irssi/src/silc/core/clientconfig.c.
3253 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * When printing the channel mode on JOIN, verify that the
3256 channel key and channel's HMAC are valid. Affected file
3257 irssi/src/silc/core/client_ops.c.
3259 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3262 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3263 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3265 * Removed channel key rekey task deleting from the function
3266 silc_server_save_channel_key. Affected file silcd/server.c.
3267 Added explicit timeout task context instead that is used to
3268 delete the task if we are registering a new task before the
3269 new task has elapsed.
3271 * When channel key rekey occurs the client library now saves
3272 the old channel key for a short period of time (10 seconds) and
3273 is able to use it in case some is still sending channel
3274 messages encrypted with the old key after the rekey. Affected
3275 file lib/silcclient/[idlist.h|client_channel.c].
3277 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Added check to the silc_server_new_id_real to not accept
3280 new ID if it is the sender's own ID. Affected file is
3281 silcd/packet_receive.c.
3283 * Assure that we do not announce ourself or the one we've
3284 sending our announcements when we're router and are announcing
3285 servers to our primary router. Affected file silcd/server.c.
3287 * Fixed silc_server_command_identify_check_client to assemble
3288 correct WHOIS packet. It send corrupted WHOIS packet and
3289 caused problem with router to router connections. Affected
3290 file silcd/command.c.
3292 Fixed also silc_server_command_whois_check the same way
3293 as for the IDENTIFY command.
3295 * Added new SilcIDListStatus to the server in the SilcIDListData
3296 structure. The status now includes the current status of
3297 the entry (like registered, resolved etc.). Affected file
3298 silcd/idlist.[ch]. Defined a bunch of different status types
3299 as well. This replaced the old boolean registered field as well.
3301 Added resolve_cmd_ident field to the SilcClientEntry structure
3302 too so that if the entry is for example being resolved so
3303 another command may attach to the same pending command reply
3304 without requiring to resolve the same entry again. This concept
3305 should optimize the WHOIS and the IDENTIFY resolving under
3306 heavy load by taking away unnecessary resolving for entries
3307 that are being resolved already.
3309 Added support for adding multiple pending commands for one
3310 command idenfier. Affected file silcd/command[_reply].[ch].
3312 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3313 before deleting the data. Otherwise the hash table will have
3314 freed data in comparison functions. Affected file is
3315 silcd/command_reply.c.
3317 * Fixed silc_idlist_replace_client_id to add the new entry to
3318 the cache with NULL nickname. Otherwise there will be invalid
3319 memory as the nickname after the nickname is freed. Affected
3320 file silcd/packet_receive.c.
3322 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3323 saved into wrong slots because the previous number of entries
3324 was not taken into account. Affected file silcd/idlist.c.
3325 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3327 * If we are router and we receive JOIN notify to a channel that
3328 does not have any users then notified client is marked as the
3329 channel founder, as it is it. The affected file is
3330 silcd/packet_receive.c
3332 * Added to the extended hash table API's table_del_*ext functions
3333 the destructor as argument too, so that the caller can decide
3334 which destructor to use or whether to use destructor at all.
3335 Affected file lib/silcutil/silchashtable.[ch].
3337 * Fixed ID Cache purging. It actually deleted the entries from
3338 the hash table after the data was freed. The hash table ended
3339 up comparing freed memory. The affected file is
3340 lib/silccore/silcidcache.c.
3342 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Fixed Irssi SILC client's KILL command's HELP syntax.
3346 * The USERS command now resolves the detailed user information
3347 if the userinfo field is missing. Affected file is
3348 lib/silcclient/command_reply.c.
3350 * Do not print error in silc_file_read if the read file does
3351 not exist. Just silently return NULL. Affected file is
3352 lib/silcutil/silcutil.c.
3354 * Fixed the silc_log_output to not wine about NULL filename
3355 and to not create some bogus " " filename. Affected file is
3356 lib/silcutil/silclog.c.
3358 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Fixed various printing bugs on the user interface in the
3361 Irssi SILC Client. Minor changes that were forgotten from
3364 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Fixed the configure.in.pre and the compilation and distribution
3367 environment to support the new autoconf 2.52. That version is
3368 now required to compile the CVS trunk.
3370 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3373 to generally parse user@fqdn format strings. Affected file
3374 lib/silcutil/silcutil.c.
3376 * Added nickname_format and nickname_force_format fields to the
3377 SilcClientParams structure. The first one defines the format
3378 for the nicknames that the library will enforce if the receives
3379 multiple same nicknames. The second one is boolean value and
3380 can be used to force the library to always enforce the format
3381 to the nicknames regardles whether there are multiple nicknames
3382 or not. This configurable formatting was employed to flexibly
3383 support accessing multiple nicknames from the user interface.
3384 The userinterface can now set the nicknames to what ever format
3385 they prefer. Affected file lib/silcclient/silcapi.h.
3387 Added function silc_client_nickname_format to the file
3388 lib/silcclient/idlist.c. It performs the nickname formatting.
3390 Added new field `hostname´ to the SilcClientEntry context.
3391 It holds the hostname of the client. Affected file is
3392 lib/silcclient/idlist.h.
3394 * Irssi SILC Client sets the nicknames in nick@hostn format.
3395 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3396 irssi/src/silc/core/silc-core.c.
3398 The WHOIS printing now also shows both the real nickname and
3399 the formatted nickname so that user knows how to access the
3400 user if there are multiple same nicknames cached. Affected
3401 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3402 printing formatting too to take the hostname now as a separate
3403 argument. The Affected file is
3404 irssi/src/fe-common/silc/modules-formats.[ch].
3406 * Changed the silc_client_get_clients_local to accept the formatted
3407 nickname as argument. It accepts the real nickname too but the
3408 formatted nickname can be used to find the true entry from
3409 multiple entries. Affected file lib/silcclient/silcapi.h and
3410 lib/silcclient/idlist.c.
3412 * Added nickname_format_parse field to the SilcClientParams.
3413 It is a callback function provided by the application to parse
3414 the nickname out of the formatted nickname string. The library
3415 calls it to get the nickname from the formatted string. Since
3416 the application generally knows better the format of the nickname
3417 string it parses it instead of the library, even though library
3418 encodes the formatted string. If the callback function is not
3419 provided then the library will use the string as is. The
3420 affected file is lib/silcclient/silcapi.h.
3422 * All the nickname strings passed to the client library in
3423 commands are now expected to be formatted nickname strings.
3424 If the command does not support the formatted nickname string
3425 it will assume that the sent string is the actual nickname.
3426 Affected file lib/silcclient/command.c.
3428 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Added public key authentication support to OPER and SILCOPER
3431 commands in the client library. Affected file is
3432 lib/silcclient/command.c.
3434 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Changed the get_auth_methdod client operation to be asynchronous.
3437 It can be async if the application resolves the authentication
3438 method from the server during the negotiation. Added new
3439 SilcGetAuthMeth completion callback that the application will
3440 call after resolving the authentication method.
3442 Added function silc_client_request_authentication_method that
3443 the application can use to resolve the authentication method
3444 from the server. Added also SilcConnectionAuthRequest callback
3445 that the library will call after the server has replied. The
3446 application can call this function if it does not know the
3447 current authentication method.
3449 Affected files are lib/silcclient/client.c and
3450 lib/silcclient/silcapi.h.
3452 * The Irssi SILC client now automatically resolves the authentication
3453 method incase any configuration information is not present (and
3454 currently there never is). The affected file is
3455 irssi/src/silc/core/client_ops.c.
3457 * Fixed public key authentication from the client library.
3458 Affected file lib/silcclient/protocol.c. Changed also the
3459 protocol specification about the public key authentication in
3460 the connection authentication protocol. The actual data to be
3461 signed is now computed with a hash function before signing.
3463 * Fixed the public key authentication from the server as well.
3464 Affected file silcd/protocol.c.
3466 * Removed the mlock()'s from the memory allocation routines.
3467 Affected file lib/silcutil/silcmemory.c. The ./configure does
3468 not check anymore for the mlock(). Affected file is
3471 * Fixed USERS command in server to allow the execution of the
3472 command for private and secret channels if the client sending
3473 the command is on the channel. Affected file silcd/command.c.
3475 * Fixed silc_client_get_clients_local to return the clients
3476 count correctly. It could return wrong value. Affected file
3477 lib/silcclient/idlist.c.
3479 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3482 types. The assembler optimizations seemed not to like 64-bit
3483 data types. The assmebler optimizations thus are now enabled
3484 also for BSD systems as opposed to only enable them for Linux.
3486 * Do not check for threads at all on BSD systems. Affected
3487 file configure.in.pre.
3489 * Removed -n and -h options from the Irssi SILC Client since
3490 they are not used in silc.
3492 * Fixed the prime generation to assure that the first digit
3493 of the generated random number is not zero since our conversion
3494 routines does not like number strings that starts with zero
3495 digit. If zero digit is seen the random number is regenerated.
3496 This caused some corrupted RSA keys when the zero first digit
3497 was met. Affected file lib/silcmath/silcprimegen.c.
3499 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Fixed WIN32 configuration in the ./configure script.
3502 Fixed to include xti.h on environments that has it.
3503 Patches by Carsten Ilchmann and andrew.
3505 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Changed the silc_id_create_client_id to be collision
3508 resistant. It is now assured that there cannot be created
3509 two same client ID's. I suspect that some weird bugs in
3510 the server were actually caused by duplicate Client IDs.
3511 Affected file silcd/serverid.[ch]. A router receiving
3512 new ID now also assures and informs the sending server
3513 if the ID caused collision.
3515 * Changed the silc_id_create_channel_id to also assure that
3516 there are no collisions.
3518 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Statement about ignoring the Mutual Authentication flag when
3521 performing rekey with PFS was a bit misleading. It is ignored
3522 if it was set in the initial negotiation, it cannot be even
3523 set in the rekey. Fixed in the ke-auth draft. Started the
3524 new versions of the protocol drafts in the doc/.
3526 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Fixed a bug in silc_client_command_identify_save when saving
3529 new channel information. The channel name was no duplicated
3530 and caused crash on exit. Affected file is
3531 lib/silcclient/command_reply.c.
3533 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Fixed the getkey command handling in the server. Send just
3536 empty OK reply to the sender if the key could not be fetched
3537 (but everything else was ok, like the key just was not available).
3538 Changed the public key parameter to optional in the protocol
3539 specs so that empty OK reply can be sent. Affected file
3542 Added a message to Irssi SILC client to tell to user if the
3543 server did not return a public key.
3545 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Fixed a channel key regeneration bug. It registered new
3548 timeout tasks exponentially until all system resources were
3549 used. Affected file silcd/server.c.
3551 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Added the SILC Document generator to the scripts/silcdoc.
3554 It can be used to generate the Toolkit Reference Manual out
3555 of the source tree. Internally it will also use the RoboDoc
3556 generator now imported in util/robodoc.
3558 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Added couple of return's in rekey protocol if error orccurred
3561 during the protocol. The execution must be terminated.
3562 Affected file silcd/protocol.c. Also, terminate the protocol
3563 always with timeout.
3565 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * The client's Client ID was created initally from the wrong
3568 nickname (it could have been in format nick@host) in the
3569 silc_server_new_client. Affected file silcd/packet_receive.c
3571 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3573 * Added some SILC_LOG_ERROR's to various error conditions
3574 if client could not be added to ID cache. Affected files
3575 silcd/packet_receive.c and silcd/server.c.
3577 * When client's sock->user_data is freed, NULL also the
3578 client->router and client->connection pointers. Added check
3579 for these pointers being NULL to various places around the
3580 code. Affected file silcd/server.c.
3582 * Added client->data.registered == TRUE checks to various
3583 places around the code to assure that unregistered client's
3584 are not handled when it is not allowed. Affected file
3587 * Added `bool registered' fields to all
3588 silc_idlist_[server|client]_get_* routines to indicate whether
3589 the fetched client needs to be registered or not. Affected
3590 file silcd/idlist.[ch].
3592 * Add your own entry as registered to the ID cache in the
3593 server. Affected file server.c.
3595 * Fixed a bug in silc_server_new_server. The SilcServer was
3596 set as the new server's context instead of SilcServerEntry.
3597 This naturally caused some weird bugs.
3599 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3601 * Do not delete the channel rekey task when adding it
3602 for in silc_server_create_channel_key.
3604 * Changed the silc_server_create_channel_key to return
3605 TRUE or FALSE to indicate the success of the channel key
3608 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Fixed MSVC++ project files and added missing files to
3611 Makefiles under win32/.
3613 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Do not add TCP_NODELAY flag if the operating system
3616 does not have it defined. Affected files are
3617 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3619 * Fixed buffer overflow from Irssi SILC Client. Affected
3620 file irssi/src/fe-common/core/themes.c.
3622 * Fixed double free in client library in the file
3623 lib/silcclient/client.c when disconnecting from server.
3625 * Applied double free patch from cras to Irssi SILC client.
3626 Affected files irssi/src/core/[modules/expandos].c
3628 * Fixed the disconnection handling to Irssi SILC Client.
3629 The application must call silc_client_close_connection
3630 in ops->connect client operation in case of failure of
3631 the connection. Affected file is
3632 irssi/src/silc/core/client_ops.c.
3634 * Do not set sock->protocol to NULL in the function
3635 silc_client_close_connection after executing the protocol's
3636 final callback since the sock might not be valid anymore.
3637 Affected file lib/silcclient/client.c.
3639 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Do not enable SILC_THREADS if the linking with libpthread
3642 did not happen. Affected file configure.in.pre.
3644 * Added notion to protocol specification that server must
3645 verify the sent authentication payload with CMODE when
3646 setting the channel founder key. Implemented it to the
3647 server. Affected file silcd/command.c.
3649 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Added _EXTRA_DIST SILC distribution variable to the
3652 distributions file. It is used to conditionally add extra
3653 files or directories to the specific distribution. Affected
3654 files ./prepare, Makefile.am.pre and distributions.
3656 Removed the `_' from the start of the distribution names.
3659 * Added README.WIN32 for instructions to compile the Toolkit
3662 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Fixed a double free in disconnection in the server. Affected
3665 file is silcd/server.c.
3667 * Fixed the lib/silcske/groups.c to work now also with GMP
3668 MP library. The string conversion did not work when using
3669 specific base and the base is indicated in the string as well.
3671 * Created win32/ directory which now includes MSVC++ specific
3672 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3673 It will appear only in the toolkit distribution
3675 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Changed the key material distribution function in case when
3678 the hash output is too short. The data is now concatenated
3679 a bit differently than it used to. Made the change to the
3680 SKE protocol specification.
3682 * Added better GMP detection to configure.in.pre. A patch
3685 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Fixed a minor bug in SKE that might cause some problem on
3688 some platforms. Affected file lib/silcske/silcske.c.
3690 * Added the cookie checking for initiator in the SKE. It checks
3691 that the responder returns the sent cookie unmodified. The
3692 affected file is lib/silcske/silcske.c. Added new SKE
3693 error type INVALID_COOKIE that can be sent during the
3694 negotiation. Fixed some memory leaks as well.
3696 * Added the "invalid cookie" error message to Irssi SILC client's
3699 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Added `task_max' field to the SilcClientParams to indicate
3702 the maximum tasks the scheduler can handle. If set to zero,
3703 default values are used. Affected file lib/silcclient/silcapi.h.
3705 * Fixed memory leaks in silc_client_close_connection. Affected
3706 file lib/silcclient/client.c.
3708 * Added silc_client_del_client_entry to client library to free
3709 all memory of given client entry. Affected file is
3710 lib/silcclient/idlist.[ch].
3712 * Added new functions silc_client_del_channel and
3713 silc_client_del_server to delete channel and server entries.
3714 Affected file lib/silcclient/[silcapi.h/idlist.c].
3716 * Removed silc_client_del_client_by_id from silcapi.h.
3718 * Fixed the INFO command to return the server's own info
3719 correctly when querying by Server ID. Affected file is
3722 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3724 * Removed the non-blocking settings in WIN32 code in the
3725 silc_sock_[read/write] and added SleepEx instead. Affected
3726 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3727 of input data is now checked with FIONREAD and ioctlsocket.
3729 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3731 * Call silc_schedule_task_del_by_context in the
3732 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3733 Affected file lib/silccore/silcprotocol.c.
3735 * Call silc_protocol_cancel for active protocols in the
3736 silc_server_close_connection if the funtion
3737 silc_server_free_sock_user_data has not been called.
3738 Affected file silcd/server.c.
3740 * Generic tasks cannot be deleted using the del_by_fd
3741 task deleting function since generic tasks does not match
3742 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3744 * Added a notion to SILCOPER help file that the SILCOPER works
3745 only on router server, not on normal server.
3747 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3749 * Added for WIN32 support for the new scheduler as well.
3750 Affected file lib/silcutil/win32/silcwin32schedule.c.
3752 * Fixed the SHA1 implementation to work on various platforms.
3754 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3756 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3757 API. It is part of the scheduler now. Everything else is
3758 as previously but some functions has changed their names.
3759 Checkout the lib/silcutil/silcschedule.h for the interface.
3760 Updated all applications to use the new interface. Affected
3761 files are lib/silcutil/silcschedule.[ch].
3763 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3765 * Found a bug in the SKE implementation. The HASH value,
3766 specified by the protocol, was not computed correctly. The
3767 public key of the responder was not added to the computation
3768 even though it is mandatory. Affected file lib/silcske/silcske.c.
3769 This unfortunately causes incompatibilities with older
3770 clients and servers.
3772 * Added WIN32 specific network init and uninit functions:
3773 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3774 the Winsock2. Affected file lib/silcutil/silcnet.h and
3775 lib/silcutil/win32/silcwin32net.c.
3777 * Set the socket always to nonblocking mode on WIN32 after
3778 reading data or writing data. Affected file is
3779 lib/silcutil/win32/silcwin32sockconn.c.
3781 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3783 * Fixed various compilation problems under WIN32. Affected
3784 files lib/silcutil/win32/silcwin32thread.c and
3785 lib/silcutil/win32/silcwin32schedule.c.
3787 * Removed all _internal.h #includes from public header
3788 files. Internal headers must never be included from
3791 Removed also the lib/silcske/payload_internal.h file.
3793 * All include files that may be needed (public and some others
3794 included by the public headers) by application developers are
3795 now copied to the ./includes directory. It does not copy any
3796 internal headers. Affected file Makefile.defines.pre and all
3797 Makefile.am's under lib/ and subdirs.
3799 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3801 * Do not change the ~/.silc directory's permissions automatically.
3802 Affected file irssi/src/silc/core/clientutil.c.
3804 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * Do not cancel the protocol in silc_server_close_connection
3807 it might cause recursion. Now cancelled in the function
3808 silc_server_free_sock_user_data. Affected file silcd/server.c.
3810 * Fixed the silc_server_remove_clients_by_server to regenerate
3811 the channel keys correctly finally. Added also new function
3812 silc_server_remove_clients_channels to actually do it.
3813 Affected file silcd/server.c.
3815 * Fixed the silc_server_new_channel to not crash by giving
3816 wrong router to the new channel. Affected file is
3817 silcd/packet_receive.c.
3819 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3822 which is given as argument to the silc_client_alloc now.
3823 It can be used to configure the client and set various parameters
3824 that affect the function of the client.
3826 * The USERS command in server did not check whether the channel
3827 is private or secret. Affected file silcd/command.c.
3829 * Added new argument to the USERS command in protocol specification.
3830 The USERS command now can take the channel name as argument
3831 as well. Added support for this in client and server and
3832 updated the protocol specs.
3834 * Completed the GETKEY command in client. It can be now used
3835 to fetch also servers public key not only some clients.
3836 Affected files lib/silcclient/command[_reply].c.
3838 * Added silc_client_get_server to return server entry by the
3839 server name. Affected files lib/silcclient/silcapi.h and
3842 * Redefined the IDENTIFY command in protocol specification to be
3843 more generic. It now can be used to query information about
3844 any entity in the SILC Network, including clients, servers and
3845 channels. The query may be based either the entity's name
3846 or the ID. Added support for this in both client and server.
3848 Affected files silcd/command.c and lib/silcclient/command.c
3849 and command_reply.c.
3851 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3852 the _from_client and _from_server functions. Affected file
3855 * Added silc_client_get_channel_by_id_resolve to the file
3856 lib/silcclient/silcapi.h to resolve channel information by
3857 its ID. Added also silc_client_get_channel_by_id that
3858 does not resolve it from the server.
3860 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3862 * Added SilcServerEntry context into the client library
3863 to represent one server. The INFO command now allocates
3864 these to save the resolved server info. For now on the
3865 client library will also keep information about servers,
3866 connected and resolved with INFO.
3868 The INFO command now allocates the SilcServerEntry context
3869 and saves the server info there. The COMMAND_REPLY in
3870 the INFO now returns the parameters to application in
3871 same order as defined in the protocol specification.
3873 The entries are cached in the client->server_cache.
3875 * The INFO command is now issued after received the Client ID
3876 from the server. Affected file lib/silcclient/client.c.
3878 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3879 to the application as the mode changer might be server.
3880 It is guaranteed that NULL is not returned anymore to the
3881 application. Affected file lib/silcclient/client_notify.c.
3883 The ID Type is now also passed to the application so that
3884 it can check whether the returned entry is SilcClientEntry
3887 Added new function silc_client_get_server_by_id to return
3888 the server entry by ID. Affected files are the
3889 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3891 * Do not create the channel in the Irssi SILC Client when issuing
3892 the JOIN command but when received the sucessful JOIN command
3893 reply. Otherwise the channel might get created even though we
3894 could not join it. The Affected file is
3895 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3897 * Fixed a channel joining bug in router. The router must also
3898 check the channel modes, invite and ban lists etc. when serving
3899 the JOIN command sent by normal server. Affected file is
3900 silcd/command.c. The router now resolves the client's
3901 information from the server who sent the JOIN command if it
3902 does not know it, and processes the JOIN command only after
3905 * Changed the SilcCommandCb to take new argument; void *context2.
3906 Affected file lib/silccore/silccommand.h
3908 The second argument in the command callbacks in the server now
3909 includes the SilcServerCommandReplyContext if the command was
3910 called as pending command callback from the command reply.
3911 Otherwise it is NULL. When called as pending the status of the
3912 command reply will be checked and if it was erronous the
3913 error will be sent to the original sender of the command.
3914 This way the client always receives the error messages even
3915 though the server was actually the one who received the error
3916 when it resent the command to router, for example. Affected
3917 files silcd/command[_reply].[ch].
3919 * Fixed sending WHOWAS command's error message to client if
3920 the requested client could not be found. It was missing.
3923 * Changed the CMODE and CUMODE commands reply arguments in the
3924 protocol specification. The Channel ID is now sent in both
3925 of the commands to identify the channel. Implemented this
3926 new feature to the client and server. Affected files
3927 lib/silcclient/command_reply.c and silcd/command.c.
3929 * Made better checks for invite and ban lists in the JOIN
3930 command in server. Affected file silcd/command.c.
3932 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3934 * The server now performs the incoming host IP/DNS lookup
3935 using the silc_socket_host_lookup and thus does not block
3936 the server anymore. Affected file silcd/server.c.
3938 * Completed the multi-thread support for SILC Scheduler in
3939 the lib/silcutil/silcschedule.c.
3941 * Fixed the configure.in.pre to detect the pthread correctly
3944 * Fixed a deadlock in silc_task_queue_wakeup in the file
3945 lib/silcutil/silctask.c.
3947 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Added new function silc_schedule_wakeup that is used in
3950 multi-threaded environment to wakeup the main thread's
3951 schduler. It needs to be used when a thread adds a new task
3952 or removes a task from task queues. After waking up, the
3953 scheduler will detect the task queue changes. If threads
3954 support is not compiled in this function has no effect.
3955 Implemented the wakeup mechanism to both Unix and WIN32
3956 systems. Affected files are lib/silcutil/silcschedule.[ch],
3957 lib/silcutil/unix/silcunixschedule.c and the
3958 lib/silcutil/win32/silcwin32schedule.c.
3960 * Added new function silc_task_queue_wakeup to wakeup the
3961 scheduler by the specified task queue. Affected file
3962 lib/silcutil/silctask.[ch].
3964 * The silc_socket_host_lookup_start now wakes up the scheduler
3965 after adding the timeout task. Affected file is
3966 lib/silcutil/silcsockconn.c.
3968 * The silc_socket_host_lookup is synchronous now if the threads
3969 support is not compiled in. However, the callback is still
3970 called asyncronously through the scheduler, anyway. Affected
3971 file lib/silcutil/silcsockconn.c.
3973 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3975 * Added new function silc_socket_host_lookup to perform
3976 asynchronous IP and FQDN lookups for the socket connection.
3977 Affected files lib/silcutil/silcsockconn.[ch].
3979 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3981 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3982 that may or may not compile the mutex support in.
3984 Changed the silc_mutex_alloc interface. It allocates the
3985 mutex now to the sent pointer and returns TRUE or FALSE.
3987 Affected file lib/silcutil/silcmutex.h.
3989 * Wrote the SILC Task Queue interface to support multi-threads.
3990 Affected file lib/silcutil/silctask.[ch].
3992 * Wrote the SILC Scheduler to support multi-threads. Affected
3993 file lib/silcutil/silcschedule.c.
3995 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3998 in lib/silcutil/win32/.
4000 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Defined SILC Mutex API and SILC Thread API and implemented
4003 them for Unix. Affected files are
4004 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4005 lib/silcutil/unix/silcunixmutex.c and
4006 lib/silcutil/unix/silcunixthread.c.
4008 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4010 * Fixed the silc_server_remove_clients_by_server's channel
4011 key re-generation. The hash table handling was incorrect
4012 and would not work with many channels. Affected file is
4015 * Fixed some memory leaks around the server code.
4017 * Rewrote the silc_server_get_users_on_channel to support IPv6
4018 based Client ID's. Affected file silcd/server.c.
4020 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4021 specification. However, a separate document must be written
4022 to define the detailed signing procedure and the payload
4023 associated with the flag. Defined the flag to the
4024 lib/silccore/silcchannel.h as well.
4026 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Changed the dynamic tables to static size tables in the
4029 lib/silccrypt/silchmac.c.
4031 * Removed GCC dependencies from the code. A patch by cras.
4033 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Do not show the error "Error receiving packet bla bla"
4036 in server if it really was not an error (-2 means that reading
4037 is pending). Affected file silcd/server.c.
4039 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Fixed a possible crash in silc_server_remove_clients_by_server
4042 in silcd/server.c. Fixed there also some memory leaks.
4044 * Fixed the silc_idlist_replace_client_id. It could replace
4045 wrong key in the hash table. Affected file silcd/idlist.c.
4047 * Do not check whether there are global users on the channel
4048 if the channel->global_users is FALSE. Affected functions
4049 silc_server_remove_from_one_channel and
4050 silc_server_remove_from_channels in silcd/server.c. Also,
4051 do not check if the removed client is local as we can be
4052 sure that global client was not removed from the channel
4053 and checking for global users is not needed.
4055 * The silc_server_remove_clients_by_server now re-generates
4056 the channel keys correctly for those channels that had
4057 clients removed from them. Affected file silcd/server.c.
4059 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Found the reason of random crashes in the server. We weren't
4062 ignoring the SIGPIPE signal (which can be sent in write())
4063 and it crashed the server. Affected file silcd/silcd.c.
4065 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Assure that sock->user_data is not NULL in the function
4068 silc_server_packet_send in silcd/packet_send.c.
4070 * Disconnect the remote connection if it could not be added
4071 to any ID lists in the server. The affected file is
4074 * Check in silc_server_packet_send[_real/dest] that the
4075 socket is not disconnecting and ignore the data if it is.
4076 Affected file silcd/packet_send.c.
4078 * Define inline to __inline on native WIN32 compilation.
4079 Affected file includes/silcwin32.h.
4081 * Added some explicit type casts for inline code since MSVC
4082 require them. Affected files lib/silcutil/silcbuffer.h,
4083 lib/trq/silcdlist.h and lib/trq/silclist.h.
4085 * Print warning in log files from now on if the packet
4086 decryption fails. Affected file silcd/server.c.
4088 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4090 * Changed the `say' client operation's interface to accept
4091 new `type' argument to indicate the type of the message sent
4092 by the library. The application may filter the library's
4093 messages according the type. The affected file is the
4094 lib/silcclient/silcapi.h.
4096 * Added two new functions to lib/silcclient/silcapi.h:
4097 silc_client_del_client and silc_client_del_client_by_id.
4098 Affected file lib/silcclient/idlist.c.
4100 * Moved the clientincludes.h from includes/ to silc/ and
4101 serverincludes.h from includes/ to silcd/.
4103 * The modes for the CMODE and CUMODE are now passed as
4104 uint32 for application with COMMAND_REPLY. The affected
4105 file is lib/silcclient/command_reply.c.
4107 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4109 * /WHOIS without arguments shows client's own information.
4110 Affected file lib/silcclient/command.c.
4112 * Changed PING to not accept any arguments. The specs
4113 says that client can ping only the connected server so
4114 requiring an argument is not needed. Affected file is
4115 lib/silcclient/command.c.
4117 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Fixed a fatal bug in private message sending and reception
4120 encryption and decryption when using private message keys.
4121 The implementation was incorrect and did not follow the
4122 specification. It causd that some of the message were
4123 lost since it did not use the sending and receiving keys
4124 as the protocol suggests. This has been fixed and will cause
4125 incompatibilities with older clients when sending private
4126 message encrypted with private message keys. Affected files
4127 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4128 and various other in Irssi SILC Client.
4130 Added `responder' boolean argument to the functions
4131 silc_client_add_private_message_key[_ske] to indicate when
4132 the key is added as responder or initiator of the key
4135 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Removed the silc_ske_check_version function and created
4138 a SilcSKECheckVersion callback. Added also a function
4139 silc_ske_set_callbacks that is now used to set all SKE
4140 callbacks. The callback functions are not given to
4141 the SKE functions anymore, but this function is used to
4144 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4146 * Added `silc_version' argument to the silc_client_alloc
4147 to define the version of the application for the library.
4148 The library will use the version string to compare it
4149 against the remote host's (usually a server) version
4150 string. Affected file lib/silcclient/silcapi.h
4152 * Added the KE protocol context to Key Agreement context
4153 in client library so that we can abort the SKE if it
4154 is in process when we get timeout. Affected file is
4155 lib/silcclient/client_keyagr.c.
4157 * Do not resolve the client ID forever if it returns in the
4158 first time that such client does not exist. This was done
4159 for example with private message. Affected file is
4160 lib/silcclient/client_prvmsg.c.
4162 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4164 * Do not add regex.h for WIN32. The affected file
4165 includes/silcincludes.h.
4167 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4168 not work yet 100%. It generates the DLL's automatically
4169 when compiling with --with-win32 under cygwin.
4171 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * lib/contrib/regex.c is not compiled on WIN32.
4175 * Added silc_net_get_socket_opt function to the
4176 lib/silcutil/silcnet.h.
4178 * Added includes/silcwin32.h for WIN32 specific includes
4181 * Do not use ptime structure or any of the posix process
4182 functions on WIN32 in lib/silccrypt/silrng.c.
4184 * Added silc_gettimeofday to provide generic function
4185 for struct timeval on all platforms. Added the function
4186 to lib/silcutil/silcutil.h.
4188 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4190 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4191 library as they clearly belong there. As a plus side we
4192 can make the actual socket connection routines platform
4195 Added also new generic function silc_socket_read and
4196 silc_socket_write (that used to be silc_packet_[read/write].
4197 The implementation of these are platform specific.
4199 * Added WIN32 specific routines of silc_socket_[read/write]
4200 to lib/silcutil/win32/silcwin32sockconn.c.
4202 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4204 * Added preliminary support for native WIN32 compilation under
4205 cygwin (using the -mno-cygwin option for GCC) to the
4206 ./configure.in.pre. The --with-win32 now prepares the
4207 compilation for native WIN32.
4209 * Rewrote the SILC Scheduler interface in the file
4210 lib/silcutil/silcschedule.h. The scheduler is now context
4211 based and does not have anymore any global static scheduler.
4212 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4213 and created lib/silcutil/win32 directory for WIN32 based
4216 * Added Unix specific network routines to the
4217 lib/silcutil/unix/silcunixnet.c and the old
4218 lib/silcutil/silcnet.c includes now only generic routines.
4220 Added WIN32 specific network routines to the
4221 lib/silcutil/win32/silcwin32net.c.
4223 * Added Unix specific utility functions from the
4224 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4226 * Added WIN32 SILC Scheduler to the file
4227 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4230 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4232 * Do not handle JOIN notify in the server if the target client
4233 is not registered (idata->registered == FALSE). The affected
4234 file is silcd/packet_receive.c.
4236 * Update the nickrec->founder in event_cumode in the Irssi SILC
4237 client. Affected file irssi/src/silc/core/silc-channels.c.
4239 * Fixed the CUMODE_CHANGE notify handling in the server when
4240 server and router are announcing their clients on channels.
4241 Now the mode changes are saved and notified correctly. The
4242 affected file is /silcd/packet_receive.c.
4244 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4245 They really did not replace the cache entry in the ID Cache.
4246 Now they do that. Affected file silcd/idlist.c.
4248 * Fixed the KICK notify handling in the Irssi SILC client to
4249 update the channel records so that the kicked client does not
4250 appear to be on the channel. The affected file is
4251 irssi/src/silc/core/silc-channels.c.
4253 * Always update the conn->current_channel when executing command
4254 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4256 * Fixed the KILL notify handling in Irssi SILC client to remove
4257 the killed client on all channels.
4259 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Fixed the silc_parse_command_line to remove extra spaces
4262 from the start and end of the arguments. Affected file is
4263 lib/silcutil/silcutil.c.
4265 * Cancel and free any active protocol in the function
4266 silc_server_close_connection. Affected file silcd/server.c.
4268 * Cancel and free any active protocol in the function
4269 silc_client_close_connction. Affected file is
4270 lib/silcclient/client.c.
4272 * Do not execute the KILL command for clients that are in
4273 history (ie. they are not in the network). Affected file is
4276 * Fixed KILL notify handling, client does not crash anymore.
4277 Affected file irssi/src/silc/core/silc-channels.c.
4279 * Reduced the default packet buffer size from 2048 to 1024 in
4280 lib/silccore/silcpacket.c.
4282 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4283 counter to the SKE context that is incresed when the SKE library
4284 performs async operation outside the library. If the outside
4285 process frees the SKE context and FREED status will be set
4286 and the library will detect after the sync operation that the
4287 libary is freed. The affected files are
4288 lib/silcske/silcske[_status].[ch].
4290 * Resolve the client entry information in the function
4291 silc_client_channel_message to assure that NULL pointer is not
4292 passed as client entry to the application. */
4294 * Fixed the task timeout calculation to assure that there is
4295 never negative timeouts. The affected file is
4296 lib/silcutil/silcschedule.c.
4298 * Fixed the channel user mode notification sending in server.
4299 It was sent point-to-point to the router (or to server by router)
4300 but it needs to be destined to a channel. The routines now
4301 supports sending the channel user mode notifys to the channels
4302 when announcing clients and channels. Affected files are
4303 silcd/server.c and silcd/packet_receive.c.
4305 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4306 It did not actually replace the old channel entry in the cache.
4307 Affected file lib/silcclient/client_notify.c.
4309 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Fixed a possible crash in silc_packet_send_prepare. It now
4312 assures always that there is enough space in the buffer and
4313 at the tail area of the buffer (for MAC).
4315 Fixed the inbound buffer reallocation in silc_packet_read.
4316 It was old code and did not handle the reallocation correctly.
4319 The affected file is lib/silccore/silcpacket.c.
4321 * Fixed buffer overflow in silc_parse_nickname in the file
4322 lib/silcutil/silcutil.c.
4324 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * make install generates new server keys only if there is not
4329 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4332 Added check that if the NOREPLY is set then we will not send
4333 the away message. This avoids infinite loop of away messages
4334 if both clients are away. The affected file is
4335 lib/silcclient/client_prvmsg.c.
4337 * Fixed client crash if /NICK was given without arguments.
4338 Affected file lib/silcclient/command.c.
4340 * Server does not send the invite list in INVITE command back
4341 to the client if the list was not altered. Added this notion
4342 to the protocol spec as well. Affected file silcd/command.c.
4344 Fixed possible crash in INVITE command by checking the
4345 value of silc_server_get_client_route command.
4347 * Fixed the INVITE notify type handling. The arguments are now
4348 taken in correct order and client does not crash. The affected
4349 file is irssi/src/silc/core/silc-channels.c.
4351 Removed the "Inviting xxx to channel" message from the
4352 client library away and let the application handle it.
4353 Affected file lib/silcclient/command.c. Added that message
4354 to Irssi SILC client's message formats.
4356 * Fixed CMODE command crash in client. It now checks the
4357 amount of arguments correctly and does not crash. The affected
4358 file is lib/silcclient/command.c.
4360 * Do not create new channel automatically in silc_channels_join
4361 but check whether the channel by that name already exists.
4362 Affected file irssi/silc/core/silc-channels.c.
4364 * Do not send the SERVER_SIGNOFF to router if the disconnected
4365 entity was the router. Affected file silcd/server.c.
4367 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4368 SILC client as it was missing from there.
4370 Added the handling of the KICK notify to the Irssi SILC client
4371 as it was missing. Added "you have been kicked" message to
4372 Irssi SILC client's message modules formats.
4374 Added the handing of the KILL notify to the Irssi SILC client
4375 as it was missing. Added the kill message module formats
4378 The affected file is irssi/src/silc/core/silc-channels.c.
4380 * The router did not save the channel mode the server announced.
4381 Affected file silcd/packet_receive.c.
4383 * Fixed a possible crash in INFO command in server. If the
4384 server did not provide the server info it crashed. Affected
4385 file silcd/command.c.
4387 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Fixed the GETKEY command in the server to check also the
4390 global list. Otherwise the GETKEY would not work correctly
4391 in normal SILC server. Affected file silcd/command.c.
4393 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed GETKEY crash, it crashed if the command did not succseed.
4397 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4400 is now real and not just an macro interface to GMP.
4402 Removed the entire GMP from the source tree and imported new
4403 NSS MPI library instead. Reason for removing GMP is that it is
4404 extremely large and compiles extremely slow. The NSS MPI
4405 is only a few files and compiles in less than 10 seconds.
4406 The speed is also about the same as GMP. The MPI is imported
4407 to lib/silcmath/mpi.
4409 If the system has GMP installed we will still use the GMP.
4410 If it is not then the NSS MPI will be compiled.
4412 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Merged a long nickname (127 characters long) crash bugfix from
4415 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4417 * Merged a freed memory reference bugfix from Irssi CVS tree.
4418 Affected file irssi/src/core/commands.c.
4420 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added the server's public key sving and verification to the
4423 server when performing the SKE. This was missing and the
4424 remote server's (or router's) public key was accepted without
4425 checking whether we have it previously or trust it at all.
4426 Affected file silcd/protocol.c.
4428 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Check in the silc_server_timeout_remote if protocol is active
4431 and make sure that the protocol's final callback is called so
4432 that all memory if freed. Affected file silcd/server.c.
4434 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * silc_server_whois_send_reply crashed the server if the nickname
4437 was 127 characters long. Affected file silcd/command.c.
4439 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Added sanity check to the silc_server_new_client. If the hostname
4442 is provided inside username then check that the provided hostname
4443 really is the same as the resolved one. If the hostname was not
4444 resolved then check it from the public key. Affected file is
4445 silcd/packet_receive.c.
4447 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4448 if the server disconnected us and the connection is not valid
4449 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4451 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4452 the library to the lib/silcutil/silcutil.[ch].
4454 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Close log file after open. Affected file
4457 lib/silcutil/silclog.c.
4459 * Check whether sock == NULL in silc_client_send_packet and return
4460 if it is. Affected file lib/silcclient/silcclient.c.
4462 * Check rec->entry == NULL in the Irssi SILC Client before
4463 sending the channel message. Affecte file is
4464 irssi/src/silc/core/silc-servers.c.
4466 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Merged a splitted window bugfix from Irssi CVS tree. The
4469 affected file is irssi/src/fe-text/textbuffer-view.c.
4471 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4472 It did not print nickname.
4474 * Improved the distributions system a bit.
4476 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4479 irssi/src/fe-text/gui-window.c.
4481 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4482 to in-active server. The affected file is
4483 irssi/src/silc/core/client_ops.c.
4485 * Resolve the client in USERS command reply if the entry does
4486 not have username resolved. The affected file is
4487 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4488 command to WHOIS command to really resolve stuff. The USERS
4489 is not used any more in any critical section so WHOIS can
4490 be used even though it might be slower than IDENTIFY.
4492 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4495 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Changed the protocol API a bit more consistent in the
4498 lib/silccore/silcprotocol.[ch].
4500 * Changed the following headers to ROBODoc format:
4502 lib/silccore/silcpayload.h
4503 lib/silccore/silcprotocol.h
4504 lib/silccore/silcsockconn.h
4506 All core library headers are now formatted.
4508 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Fixed a bug in Irssi SILC client; do not show that you are
4511 server/router operator if you really are not. Affected file is
4512 irssi/src/silc/core/client_ops.c.
4514 * Renamed silc_command_free_payload to silc_command_payload_free.
4515 Affected file lib/silccore/silccommand.h
4517 * Added silcmath.h to include the prototoypes of various routines
4518 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4521 * Changed the following headers to ROBODoc format:
4523 lib/silccore/silcchannel.h
4524 lib/silccore/silccommand.h
4525 lib/silccore/silcid.h
4526 lib/silccore/silcidcache.h
4527 lib/silccore/silcmode.h
4528 lib/silccore/silcnotify.h
4529 lib/silccore/silcpacket.h
4530 lib/silcmath/silcmath.h
4532 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Added checking to the server code not to start the server if
4535 ciphers and stuff are not configured properly. Affected files
4536 silcd/serverconfig.[h] and silcd/server.c.
4538 * Changed the layout of the header files of the public interfaces
4539 in the SILC libraries. The new layout supports ROBODoc
4540 documentation tool (and some others) so that it is easy to create
4541 a library reference manual. All the other headers and source
4542 code must still follow the CodingStyle document. Also source
4543 code must not include these ROBODoc stuffs, only the headers.
4544 Furthermore, all public interface headers must now be named
4545 by using `silc' prefix, example: silcapi.h, silccipher.h.
4546 Some files were renamed due to this. All the other headers
4547 must not be used as public interfaces. I will update the
4548 CodingStyle document later. Changed following headers, so far:
4550 lib/silcclient/silcapi.h
4551 lib/silccore/silcauth.h
4552 lib/silccore/silcprivate.h
4553 lib/silccrypt/silcdh.h
4555 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Removed silc_client_packet_send_flush from the client library
4560 as it is not needed. Affected file lib/silcclient/client.[ch].
4562 * Added printing of message of unresolved authentication method
4563 to the Irssi SILC client. Added it to the module formats.
4564 Removed the same message from the client library.
4566 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added new distribution feature, DISTLABEL. Every distribution
4569 can define own preprocessor label that can be used in the
4570 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4571 file distributions, acconfig.h.pre and prepare.
4573 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added Makefile.defines_int to include the actual definitions
4576 for Makefile.defines.in. Tested the new distribution system,
4577 created distributions and tested installation.
4579 * Added AWAY message printing to the Irssi SILC client. Added
4580 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4582 * Added SCONNECT command to call the SILC's CONNECT command.
4583 Cannot use CONNECT directly since Irssi uses that internally.
4584 Affected file irssi/src/silc/core/silc-servers.c.
4586 Added ACTION local command. It is same as ME command but takes
4587 the channel as mandatory argument.
4589 Rewrote some of the Irssi's help files to suite for SILC
4592 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added Makefile.defines[.in] that should for now on be included
4595 in all Makefile.am file in the source tree. That file includes
4596 all common compilation definitions for SILC source tree.
4598 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Minor changes to the ./prepare script to change the package
4601 name according the distribution name to the configure.in.
4603 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Created new distribution system. Added file `distributions'
4606 that defines all the distributions that can be created out of
4607 the SILC source tree. The ./prepare script now reads that
4608 file to determine how to prepare the distributions. The
4609 first argument to the ./prepare is the name of the distribution
4610 and second is the version of the distribution. If given
4611 without arguments it creates the default (toolkit) distribution
4612 with the default version (defined in ./prepare).
4614 All Makefile.am files that are subject to the distributions
4615 are now named as Makefile.am.pre. These are ./Makefile.am
4616 and lib/Makefile.am. Others may be changed later.
4618 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Added invite list, ban list, some key management and connection
4621 error message printing to module formats in the Irssi SILC client.
4623 * Added new silc_client_set_away_message to set the away message
4624 that is back to the person who sent private message. The
4625 affected file lib/silcclient/silcapi.h and the
4626 lib/silcclient/client_prvmsg.c.
4628 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Fixed the private message sending in the Irssi SILC client,
4631 added local command KEY to the Irssi SILC client.
4633 Added key management and key agreement message formats to the
4634 irssi/src/fe-common/silc/module-formats.[ch].
4636 Added USERS (alias WHO) printing, server/router operator
4637 indication and LIST command printing to the module formats.
4639 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed channel joining notify handling, cumode notify handling
4642 from Irssi SILC client.
4644 * Added SILC specific module-formats to the Irssi SILC client so
4645 that SILC specific message hilighting, colors etc is possible.
4646 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4648 Added channel mode, channel user mode, actions, notices,
4649 whois and whowas printing to the the module-formats.c.
4651 * Fixed a bug in channel deletion in the server. The channel
4652 is not left to the cache even if the channel founder auth mode
4653 is set when there are no users anymore on the channel. Affected
4654 file silcd/server.c.
4656 * The silc_net_localhost now resolves the entire hostname including
4657 the domain name. Affected file lib/silcutil/silcnet.c.
4659 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Changed the ask_passphrase client operation to be ascynchronous.
4662 It has now a completion callback and a context that the
4663 application must call after it has got the passphrase from
4664 the user. Affected files lib/silcclient/silcapi.h,
4665 lib/silcclient/protocol.c, lib/silcclient/command.c and
4668 Added SilcAskPassphrase callback that the application calls
4669 to deliver the passphrase to the library.
4671 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4672 The public key verification and especially a certificate
4673 verification is asynchronous procedure.
4675 Added new SILC_SKE_STATUS_PENDING status to indicate the
4676 request is pending and a callback will be called to finalize
4679 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4680 indicate that remote end did not send its public key (or
4681 certificate), even though we require it. Added check for this
4682 condition in the SKE. This was a security bug, now fixed.
4684 Defined new SilcSKEVerifyCbCompletion callback that is called
4685 when the verification process is completed.
4687 The affected files lib/silcske/silcske_status.h and
4688 lib/silcske/silcske.[ch].
4690 * Changed the verify_public_key client operation to be async
4691 as well. Defined SilcVerifyPublicKey callback that is used to
4692 indicate the success of the public key verification process.
4694 Changed the server and client to use the new async client
4697 * Changed the Irssi SILC client's internal scheduler to be called
4698 twice as many times as it used to be. As a result the client
4699 should be a bit faster now. Affected file is
4700 irssi/src/silc/core/silc-core.c.
4702 * Added support to Irssi SILC client of asynchronous public key
4703 verification and passphrase inquiry. Affected file is
4704 irssi/src/silc/core/silc-core.c.
4706 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Do not say "You have left channel %s" in client library.
4709 Moved it to the application. Affected files are
4710 lib/silcclient/command.c and silc/client_ops.c.
4712 * Fixed silc_client_get_clients. Command context was not
4713 duplicated and was freed memory in the callback. Affected
4714 file lib/silcclient/idlist.c.
4716 * Do not say "you are now talking..." on JOIN command in the
4717 client library. The appliation must handle it.
4719 * Do not say ".. changed topic to" in command reply in the
4720 client libary. The application must handle it.
4722 * Fixed TOPIC command sending in the client library.
4724 * Fixed a memory leak in silc_client_command_free in the file
4725 lib/silcclient/command.c.
4727 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Imported a modified version of Irssi client to the source tree.
4730 The Irssi will be used to create a new client called
4731 Irssi SILC. Imported to irssi/.
4733 Added silc_core_init_finish function to the Irssi. Affected
4734 file irssi/configure.in.
4736 A lot changes in the Makefile.ams around the irssi tree.
4738 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Do not rehash if the new size is same as the old size of the
4741 hash table, in the silc_hash_table_rehash*. The affected file
4742 lib/silcutil/silchashtable.c.
4744 * Replaced hash_table_del_by_context calls from the server
4745 (when channel->user_list and client->channels) to the
4746 hash_table_del as it is sufficient and faster.
4748 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added silc_hash_table_list, silc_hash_table_get and the
4751 SilcHashTableList structure to provide an alternative way to
4752 traverse the hash table. The affected files are
4753 lib/silcutil/silchashtable.[ch].
4755 * Changed the server's idlist routines to use the hash table
4756 routines to optimize the code.
4758 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Replaced the client entry's `channel' list and channel entry's
4761 `user_list' list to hash tables for optimized lookup. Changed
4762 the code to use the hash table interface around the code.
4763 Affected file lib/silcd/idlist.[ch].
4765 * Added `auto_rehash' boolean argument to the function
4766 silc_hash_table_alloc to indicate whether the hash table should
4767 auto-rehash when it thinks is appropriate time. It will
4768 increase the hash table size if the there is twice as much
4769 entries in the table than the size of the table, and will
4770 decrease the size if there are twice as less entries than
4771 the size of the table.
4773 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4777 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * silc_idcache_purge_by_context deletes the entry now by context
4780 as it is supposed to do. Affected file lib/silccore/idcache.c.
4782 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4783 client is not anymore valid (WHOWAS givens the info) and not
4784 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4786 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Removed the `data' and `data_len' arguments from the ID Cache
4789 interfaces and added `name' argument. ID Cache does not handle
4790 anymore the binary data only a names associated with given ID.
4792 * When hashing a Client ID with silc_hash_id the entire ID is
4793 not hashed anymore, instead only the hash of the Client ID is
4794 hashed. This way we can access the Client ID from the cache
4795 with Client ID but with the hash of the ID (which is a hash of
4796 the nickname) as well without any difference in performance.
4798 Added also silc_idcache_find_by_id_one_ext to do one on one
4799 searching when we have the actual ID. Added also function
4800 silc_hash_client_id_compare. The affected files are
4801 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4803 * When hashing the name associated with a ID it is always done
4804 in lowercase. This way we can access the cache without worrying
4805 about case-sensitivity, even though, for example nicknames are
4808 * Fixed a bug in server with channel message sending. It put
4809 wrong ID type as destination ID. The affected file
4810 silcd/packet_send.c.
4812 * silc_idcache_del_by_context now deletes from all hash tables
4813 by context. Affected file lib/silccore/idcache.c.
4815 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Changed the client library to use the new ID Cache interface.
4818 Changes around the source tree.
4820 * Added silc_hash_table_rehash_ext to rehash with specific
4821 hash function. Affected file lib/silcutil/silchashtable.[ch].
4823 * Added silc_hash_string_compare to compare two strings in the
4824 hash table. Affected file lib/silcutil/silcutil.[ch].
4826 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added new function silc_idcache_del_by_context into the
4829 lib/silccore/idcache.[ch].
4831 * Changed the server's ID list routines to use the new ID Cache
4832 interface. Changes around the source tree.
4834 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added silc_hash_table_del[_by_context]_ext functions in to the
4837 lib/silcutil/silchashtable.[ch].
4839 Removed silc_hash_table_find_all* routines and added new
4840 silc_hash_table_find_foreach to replace them.
4842 Added silc_hash_table_replace_ext function as extended
4843 replacing function. Separated the simple hash table interface
4844 from the extended hash table interface in the file
4845 lib/silcutil/silchashtable.h.
4847 * Fixed minor bugs and changed it to use some of the new
4848 hash table functions in lib/silccore/idcache.c
4850 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added new function silc_hash_table_find_all to return all keys
4853 in the hash table by the specified key. As the hash table is
4854 collision resistant it also makes it possible to have several
4855 duplicate keys in the hash table. This function may be used to
4856 find all of the keys from the hash.
4858 Added user_context arguments to the SilcHashFunction,
4859 SilcHashCompare and SilcHashDestructor to deliver user specified
4862 Added new fuctions silc_hash_table_find[_all]_ext to do
4863 extended lookup with specified hash and compare functions and
4864 specified user contexts.
4866 Added new function silc_hash_table_add_ext to add the key
4867 with specified hash function and user context.
4869 Added new function silc_hash_table_foreach to traverse all
4870 entrys in the hash table. Added SilcHashForeach callback
4873 Added new function silc_hash_table_del_by_context to delete
4874 the entry only if the context associated with the key matches.
4876 Affected files are lib/silcutil/silchashtable.[ch].
4878 * Removed silc_hash_[server/client/channel]_id and added just
4879 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4880 silc_hash_id_compare to compare two ID's using as the hash table
4881 comparison function. Added also silc_hash_data to hash
4882 binary data and silc_hash_data_compare to compare it.
4884 * Removed silc_idlist_find_client_by_hash as it is not needed
4885 anymore. Affected file silcd/idlist.[ch].
4887 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4888 to use internally the SilcHashTable. The new ID Cache is a lot
4889 faster than the old one. Some of the ID Cache interface was also
4890 rewritten and obsolete and stupid functions were removed.
4892 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Added entry_count field to the SilcHashTable to keep the number
4895 of the entries in the table. Implemented the function
4896 silc_hash_table_rehash. Added new function
4897 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4899 Fixed a minor bug in silc_hash_table_free.
4901 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4902 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4903 into the lib/silcutil/silcutil.[ch].
4905 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Implemented a collision resistant hash table into the
4908 lib/silcutil/silchashtable[ch]. See the header and the source
4909 for the SilcHashTable API.
4911 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Merged dotconf version 1.0.2 into lib/dotconf.
4915 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Do not compile anything in lib/silcsim/* if the SIM support
4918 is not enabled. The tree should now compile without problems
4921 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Compiled the SILC under cygwin. Compiled and tested briefly
4924 without problems. More tests needed. The SIMs didn't compile
4927 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4929 * Fixed possible crash in silc_get_username in the
4930 lib/silcutil/silcutil.c.
4932 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Fixed a va_arg in silc/client_ops.c.
4936 * Oops, RC5 routines were named AES and caused some problems
4937 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4939 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Added new SilcIDIP structure into the lib/silccore/id.h and
4942 replaced the old `ip' fields from all SILC ID's to that type.
4943 This is a step towards IPv6 support.
4945 The silc_id_get_len takes now the ID as an extra argument.
4946 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4947 both IPv4 and IPv6 based ID's.
4949 The affected files are lib/silccore/id.[ch] and other files
4950 around the tree using these routines.
4952 * Removed the ID length arguments in server from various
4953 silc_server_send_notify_* routines -> they are not needed
4956 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Fixed memory leak in silc_encode_pem_file in the file
4959 lib/silcutil/silcutil.c.
4961 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Check minor version as well in the SKE. Affected files are
4964 silcd/protocol.c and lib/silcclient/protocol.c.
4966 * Added --identifier option to the server so that an identifier
4967 can be when creating the public key for the server. Affected
4968 file is silcd/silcd.c.
4970 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4971 lib/silccrypt/silcpkcs.c.
4973 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Register default ciphers and stuff when using -C option with
4976 the server. Affected file sildc/silcd.c.
4978 * Put back the servers public key filename format, it is better
4979 than the new one. For now, the client keys are saved with the
4980 new filename format. The affected file silc/client_ops.c.
4982 * Implemented the Cipher API for the rest of the ciphers that
4983 did not implement it or implemented it the wrong way.
4985 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Register default ciphers and stuff when using the -S option
4988 in the client. Affected file silc/silc.c. Same also when
4989 creating new key pair with -C option.
4991 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Fixed the silc_verify_public_key client operation function to
4994 save the public keys differently. The fingerprint is now
4995 used as filename and not the hostname. This way also the
4996 client keys are saved uniquely and not with hostnames. The
4997 affected file is silc/client_ops.c.
4999 * Trimmed the silc_hash_fingerprint function to remove extra
5000 whitespaces from the end of the fingerprint. The affected
5001 file is lib/silccrypt/silchash.c.
5005 * Added silc_cipher_register_default function to register all
5006 default ciphers. It can be used when configuration files
5007 does not exist and the application does not want any specific
5008 ciphers in any specific order.
5010 The SilcDList is now used as silc_cipher_list dynamically
5011 allocated cipher list. Removed the static list all together
5012 and now all ciphers must be allocated to the dynamic list.
5013 The silc_cipher_alloc routine was changed to check only the
5016 All silc_cipher_* routines that used to return int returns
5019 The affected files lib/silccrypt/silccrypt.[ch].
5021 * The same thing was done to silc_hash_* as for silc_cipher_*
5022 routines. Affected files lib/silccrypt/silchash.[ch].
5024 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5025 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5026 Added also silc_pkcs_[un]register[_default] functions.
5027 Removed the data_context from the PKCS API.
5029 * Added silc_hmac_register_default function to register default
5030 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5031 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5032 to unregister all hmacs at once.
5034 * Register the default ciphers, hash functions, PKCSs and HMACs
5035 if client's configuration file does not exist. The affected
5038 * The client did not load the hash functions from the SIM
5039 modules at all. Added support for this. Affected file is
5040 silc/clientconfig.c.
5042 * When decoding public key with silc_pkcs_public_key_decode, check
5043 the supported algorithm only if PKCS are registered. Affected
5044 file lib/silccrypt/silcpkcs.c. The same was done with the
5045 silc_pkcs_private_key_decode.
5047 * Fixed the SILC List routines to keep the list always in order.
5048 It used to change the list's order when traversing the list but
5049 not it preserves the order. Affected file lib/trq/silclist.h.
5051 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Added the client library to use the SilcSocketConnection's
5054 reference counter (by silc_socket_dup) to prevent the bug that
5055 the socket object may be freed underneath async operation.
5057 * The name resolv library checking fixes in the configure.in.pre.
5060 * Created new version of the protocol drafts for future
5061 development. The -03 drafts are the ones that will be changed
5062 in the trunk now and the -02 will remain as they are.
5064 * Send list of CUMODE notifys to the router when announcing
5065 the channel users to the router. Affected file silcd/server.c.
5066 If the router receiving channel founder CUMODE for a channel
5067 that already has channel founder it will send CUMODE notify
5068 to the sender to remove the channel founder rights from the
5069 announced client. Affected file silcd/packet_receive.c.
5071 * The CUMODE notify may now use Server ID as well as the entity
5072 who changes the mode. Updated protocool specs.
5074 * Updated INSTALL and README files.
5076 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * New web pages in the http://silc.pspt.fi. The pages was
5083 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Implemented the [DenyConnectin] config section in the server.
5086 Added silc_server_config_denied_conn to check whether incoming
5087 connection is denied. Affected file silcd/serverconfig.[ch].
5089 * Do not check the ports when checking the incoming configuration
5090 data if the port is 0, meaning any. Affected file is
5091 silcd/serverconfig.c.
5093 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Fixed buffer overflow in silc_string_compare in the file
5096 lib/silcutil/silcutil.c.
5098 * Fixed double free in silc_server_command_leave in the file
5101 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Fixed the version checking in the server. Affected file is
5106 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Fixed the configuration data fetching when accepting new
5109 connections in the server. Affected file silcd/server.c.
5111 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added `sender_entry' argument to the function
5114 silc_server_packet_relay_to_channel so that we can check
5115 whether some destination actually belongs to the same route
5116 the sender belongs (ie, we must not resend the packet to the
5117 sender). Affected file silcd/packet_send.[ch].
5119 * Added `servername' field to the SilcClientEntry in the server
5120 to hold the name of the server where client is from. Affected
5121 file is silcd/idlist.h.
5123 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Moved the channel message encrypting in the router betwen
5126 router connections from silc_server_channel_message to the
5127 silc_server_packet_relay_to_channel since we want to check
5128 whether we have anybody channel before encrypting anything.
5129 Affected files silcd/packet_[receive/send].c.
5131 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Fixed the [AdminConnection] server config section to support
5134 multiple entries. Affected file silcd/serverconfig.c.
5136 * Added support into the server to check the validity of the
5137 incoming connection before executing any KE or authentication
5140 * The connection configuration is now saved to the KE and
5141 connection auth protocol contexts and not fetched anymore in
5142 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5144 * The local hosts listenning address and port is also resolved
5145 now when starting the server. We want to have the socket object
5146 to include the real address and port for the listener. Added
5147 new function silc_net_check_local_by_sock into the files
5148 lib/silcutil/silcnet.[ch].
5150 * Fixed a broadcast bug in server -> do not broadcast if we
5153 * Fixed a routing bug. Do not route broadcast packets ever.
5154 Broadcast packets must be processed always and not routed since
5155 they may be destined to some other host than yourself and thus
5156 would get routed without no good reason. Affected file is
5159 * Added function silc_server_config_is_primary_route to check
5160 whether primary router connection has been configured (a router
5161 configuration that we are initiating). If there is not, we
5162 will assume that there is only two routers in the SILC network
5163 and we will use the incoming router connection as our primary
5164 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5166 * Changed the order of the broadcasting. Broadcast _after_ the
5167 packet has been processed not before. Affected file is
5170 * Fixed a [ClientConnection] parsing bug. The port was never
5171 parsed correctly thus resulting to port 0. Affected file
5172 silcd/serverconfig.c.
5174 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5175 argument and did not set the broadcast packet flag. Affected
5176 file silcd/packet_send.c. Fixed same bug in the function
5177 silc_server_send_notify as well.
5179 * If we receive NEW_ID packet for our own ID in the server, ignore
5182 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Removed the nickname from the Private Message Payload.
5187 Updated the code and the protocol specs.
5189 * Updated protocol specs for submitting to the IETF.
5191 * Tweaked the Random Number Generator a bit. Affected file
5192 lib/silccrypt/silcrng.c. Exported a new function
5193 silc_rng_[global]_add_noise which can be used to add more
5196 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Do not parse packets with different timeout when protocol
5199 is active -> may cause problem with rekey. Affected file
5202 * When server receives signoff notify it must not create
5203 new channel key if the client is on any channels since the
5204 sender of the signoff notify will create it.
5206 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added printing of error messages during SKE protocol from the
5209 failure packet sent by server during SKE. Affected file
5212 * Removed the client's failure_callback handling with timeout
5213 and handle it immediately when received.
5215 * The SKE library returned wrong type in SUCCESS and FAILURE
5216 packets. They must be 32 bit MSB not 16 bit MSB.
5218 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Ok, rewrote the logic of the re-key and now it seems to work.
5221 I tested it on high traffic with frequent re-keys without
5222 problems. Added hmac_receive (and renamed hmac to hmac_send)
5223 in SilcClientConnection in lib/silcclient/client.h and
5224 in SilcIDListData in silcd/idlist.h. Also, removed the
5225 SilcPacketParserContext's cipher and hmac fields as they are
5226 not needed anymore and actually caused some problems when
5227 the ciphers and hmac's changed underneath the packet parser.
5229 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * If re-key protocol is active then process the incoming packets
5232 synchronously since we must assure that icoming packets encrypted
5233 with the old key is processed before the new keys is set to
5234 use. This is true other packets than for REKEY packets.
5235 Affected file silcd/server.c. The same was done to client library
5236 as well, affected file lib/silcclient/client.c.
5238 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Fixed bug in client and server to accept the force send if
5241 the packet is send from silc_[server/client]_packet_process
5242 function. Otherwise the packets are never delivered, oops.
5244 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Disable force sending of packets when REKEY protocol is active.
5247 We must assure that no packet is sent directly when rekey is
5248 performed. All packets must be sent through packet queue.
5249 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5250 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5251 function is silc_[server/client]_packet_send_real to check
5254 * Replaced the SIM paths from example config files to
5255 /usr/local/modules. Also, make install creates now
5256 /usr/local/silc/logs directory to hold all the SILC server
5259 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Made the configure.in.pre work on Solaris. Patch by salo.
5263 * Made all ciphers compatible with non-x86 machines. Defined
5264 CBC mode macros into lib/silccrypt/ciphers_def.h.
5266 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed the make install.
5270 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * When MAC computation fails the silc_packet_decrypt returned 0
5273 even though it was supposed to return -1. Fixed this. The
5274 affected file is lib/silccore/silcpacket.c.
5276 * Do not replace the config files in /etc/silc (in make install)
5277 if they already exist. Affected file ./Makefile.am.
5279 * Do not send re-key packets immediately but through packet queue.
5280 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5282 * Changed silc_net_check_host_by_sock to return FALSE if the
5283 IP/DNS could not be resolved. Though, it returns the IP address
5284 now even if it could not resolve it (but returns also FALSE).
5285 Affected file lib/silcutil/silcnet.[ch].
5287 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Added silc_pkcs_decode_identifier to decode the public key's
5290 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5291 Added also silc_pkcs_free_identifier. Added also new context
5292 SilcPublicKeyIdentifier.
5294 * Added -S option to the silc client. It is used to dump the
5295 contents of the specified public key file.
5297 * Changed the PKCS api to return the public key length when
5298 setting the public key.
5300 * Fixed a fatal bug in the public and private key file loading.
5301 Affected file lib/silccrypt/silcpkcs.c.
5303 * Execute the packet parsing for client with zero (0) timeout
5304 if the protocol is active. Affected file silcd/server.c.
5306 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Made the key generation options to the silcd program. Added
5309 -C option, equivalent to client's option.
5311 * Added new [ServerKeys] config section to the server. It
5312 configures the server's public and private key.
5314 * Defined generic Public Key Payload into the protocol
5315 specification to send specific type of public keys and
5318 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5319 public key or certificate.
5321 * Implemented the GETKEY command to the server and to the
5322 client library and on user interface.
5324 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Made preliminary `make install' work.
5328 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5330 * Added SilcServerRekey context into silcd/idlist.h.
5332 * Added the PFS support as defined in the specification to the
5333 SKE protocol. Affected files lib/silcske/*.c.
5335 * Added `ske_group' field to the SilcServerRekey context to hold
5336 the number of the SKE group that is used with PFS in re-key.
5337 Affected file silcd/idlist.h.
5339 * Added PFS re-key support to the server. Affected file is
5342 * Added silc_protocol_cancel to cancel execution of the next
5343 state of the protocol. Affected file is
5344 lib/silccore/silcprotocol.[ch].
5346 * Added the re-key support with and without PFS to the client
5347 library. Re-key is performed once in an hour, by default.
5349 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5350 Added silc_client_rekey_callback and silc_client_rekey_final.
5351 Affected files are lib/silcclient/protocol.[ch] and
5352 lib/silcclient/client.[ch].
5354 * Removed the `hmac_key' and `hmac_key_len' fields from the
5355 SilcClientConnection structure; not needed. Affected file is
5356 lib/silcclient/client.h.
5360 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Do not ask whether user wants to use the negotiated private key
5363 for private messages, just use it. Affected file is
5364 silc/local_command.c.
5366 * Added `send_enc_key' and `enc_key_len' fields to the
5367 SilcIDListData structure since they are needed in the re-key
5368 phase. Affected file is silcd/idlist.[ch].
5370 * Implemented the simple re-key protocol into the server.
5371 Affected files silcd/server.c and silcd/protocol.[ch]. The
5372 re-key will be performed once in an hour, by default.
5374 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5375 Added silc_server_rekey, silc_server_rekey_callback and
5376 silc_server_rekey_final.
5378 * Removed Tunneled flag from the protocol. Updated the code
5379 and the specifications.
5381 * Adde `pfs' field to the SilcIDListData to indicate whether
5382 the PFS is to be performed in the re-key. Affected file is
5385 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5388 int64 of at least the xintXX size. If void * is less that 4
5389 bytes uint32 * will be used. Defined bool as boolean.
5391 * Changed _ALL_ unsigned long and unsigned int to uint32,
5392 unsgined short to uint16 in the source tree.
5394 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5395 not handle clients that has entry->data.registered == FALSE.
5396 They are not in the network anymore. Affected file is
5399 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Implemented the sending of the SERVER_SIGNOFF notify in the
5402 server. Affected file is silcd/server.c.
5404 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5405 Added also silc_notify_payload_encode_args into the
5406 lib/silccore/silcnotify.[ch].
5408 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5409 Affected file silcd/packet_receive.c.
5411 * Implemented the SERVER_SIGNOFF notify handling in the client
5412 library. Affected file lib/silcclient/client_notify.c. Also,
5413 implemnted the printing of the SERVER_SIGNOFF info to the
5414 application. Affected file silc/client_ops.c.
5416 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5417 if the deleting was successful. Affected file silcd/idlist.[ch].
5419 * Added support for public key authentication in the connection
5420 authentication protocol in the client library. Affected file
5421 lib/silcclient/protocol.c.
5423 * Changed the server's silc_idlist_get_clients_by_* interface
5424 to support already allocated array so that new entries may be
5425 added to pre-allocated array. Affected file silcd/idlist.[ch].
5426 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5427 and command replies.
5429 * All command reply functions in the server now calls the
5430 pending command callback even if error occured. This way the
5431 error will be delivered to the client as well. Affected files
5432 silcd/command.c and silcd/command_reply.c.
5434 * Fixed INFO command to return local server's info if no server
5435 was provided. Affected file lib/silcclient/command.c.
5437 * Removed RESTART command for good. Updated the code and the
5440 * Rewrote parts of the task system. It is a bit simpler now.
5441 Removed unsued task priorities. The affected files are
5442 lib/silcutil/silctask.[ch].
5444 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Moved the USERS printing from the library to the application.
5447 Affected files lib/silcclient/command.c and silc/client_ops.c.
5449 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Added channel key re-key support. The re-key is perfomed
5454 only by the router and is done once in an hour. Added `rekey'
5455 field to the SilcChannelEntry in the server. Affected files
5456 silcd/server.c and silcd/idlist.h.
5458 * Added silc_task_unregister_by_context into the file
5459 lib/silcutil/silctask.[ch].
5461 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Added SILC_UMODE_GONE mode to indicate when the client is not
5464 present in the SILC network. Added also support to the local
5465 command AWAY that will set this mode. Added support of showing
5466 "xxx is gone" in WHOIS command. The USERS command shows the
5467 gone status as well.
5469 * Fixed setting server and router operator privileges in the
5470 server's UMODE command. Affected file silcd/command.c.
5472 * Merged the SKE KE1 and KE2 payloads into one payload. The
5473 new KE payload is equivalent to the old KE2 payload.
5475 Cleaned up the SKE Start Payload parsing. It now uses the
5476 simple buffer unformatting to do the parsing. A lot faster
5479 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5480 to the SKE that is used to indicate whether both of the SKE
5481 parties should perform authentication. By default only the
5482 responder performs authentication. By setting this flag also
5483 the initiator must do authentication. By default it is unset
5484 since in normal SKE case, client to server connection, only
5485 the responder should do authentication. When doing SKE between
5486 two clients both should perform authentication. Updated the
5487 code and the protocol specs.
5489 * A little fix to IDENTIFY command in the server. Search the
5490 client first by hash not nickname. Affected file is
5493 * Fixed the silc_client_close_connection to support closing
5494 the client to client connections wihtout deleting too much
5495 data. Affected file lib/silcclient/client.c.
5497 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5498 are received if protocol used to be active but is not anymore
5499 the application would crash due to NULL pointer dereference.
5500 Affected files silcd/server.c and lib/silcclient/client.c.
5502 * Added `hash' field to the SilcClientConnection to include
5503 the hash function negotiated in the SKE protocol.
5505 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5506 to set the channel founder authentication data. A client can
5507 claim the founder rights later by providing the authentication
5508 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5509 This way the channel founder can regain the channel founder
5510 privileges even it is left the channel. This works only on
5511 local server and the client must be connected to the same
5512 server to be able to regain the founder rights. Updated the
5513 protocol specs accordingly.
5515 Added support to the CMODE command in the client to set the
5516 founder auth data. Read the README to see how to set it.
5518 Added support to the CUMODE command to claim the founder
5519 rights. Read the README to see how to do it.
5521 Added support for the founder authentication to the Channel
5522 Entry in the server. Affected file silcd/idlist.h.
5524 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5525 server's CMODE command. Affected file silcd/command.c.
5527 * Added the following new functions into lib/silccore/silcauth.[ch]:
5528 silc_auth_get_method and silc_auth_get_data.
5530 * The server now saves the remote hosts public key to the
5531 SilcIDListData pointer. Affected file silcd/protocol.c.
5533 * The normal server now does not remove the channel entry from
5534 the cache if the founder authentication data is set. It used
5535 to remove it if the founder was the last one on the channel on
5536 the server and left the channel. The auth data is saved and
5537 if the channel is re-joined later the old entry is used with
5538 the old auth data. Affected files silcd/command_reply.c and
5541 * Removed the `pkcs' field from the SilcIDListData structure
5542 in the server; it is not used. Affected file silcd/idlist.h.
5544 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed packet processing on slow links. Partial packets were
5547 never re-processed because the incoming data buffer was cleared
5548 by the application. Application must not directly clear the
5549 sock->inbuf, the packet processing routines handle it. Fixed
5550 this in client library and in server.
5552 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Fixed the WHOIS and IDENTIFY send reply function to really
5555 check whether to send list or just one entry. Affected file
5558 * Cleaned up the LEAVE command's channel key distribution. The
5559 affected file silcd/command.c.
5561 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5562 can enforce the channel mode as well. In that case the ID
5563 includes the ID of the server. The code now enforces the
5564 mode change if the router have different mode than the server.
5566 * The notify client operation with CMODE_CHANGE notify can now
5567 return NULL client_entry pointer if the CMODE was not changed
5568 by client. Application must check for this.
5570 * Added <Server ID> argument to INFO command to support server
5571 info fetching by Server ID.
5573 * Added silc_server_announce_get_channel_users to get assembled
5574 packets of channel users of the specified channel. Affected
5575 file silcd/server.[ch].
5577 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5578 was freed underneath the ID Cache.
5580 * Re-announce clients when the server received CHANNEL_CHANGE
5581 notify from the router. Affected file silcd/packet_send.c.
5583 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5586 crashed since it did not handle the fact that there is no cipher
5587 called "3" and didn't check the error condition. Now fixed.
5589 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5590 flag. It can be used to send message requests.
5592 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Implemented the RESTART command in the client.
5596 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5597 notice type messages. Added notice printing to the user
5600 * The channel keys are not re-generated if the channel's mode
5601 is PRIVKEY, ie private key on the channel exists. Affected
5602 files silcd/server.c and silcd/command.c.
5604 * Fixed a little bug in channel message delivery when channel
5605 private keys are set in the server. Affected file is
5606 silcd/packet_send.c.
5608 * Changed the setting on channel->on_channel = TRUE from the
5609 silc_client_save_channel_key to the JOIN command reply. The
5610 key payload is not received if the private channel key is set.
5611 Affected file lib/silcclient/command_reply.c and the
5612 lib/silcclient/client_channel.c.
5614 * When the CMODE_CHANGE notify is sent and the channel private
5615 key mode is removed the channel key must be re-generated in
5616 other cells as well. Added this support for the router in the
5617 silcd/packet_receive.c.
5619 * Added new local command NOTICE to send notice message on
5620 channel. Affected file silc/local_command.[ch].
5622 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Added new local command ME to the client. It is used to send
5625 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5626 some action. Affected file silc/local_command.[ch].
5628 * Changed channel_message and private_message client operations
5629 to deliver the message flags to the application. Added also
5630 the `flags' arguments to the silc_client_send_channel_message
5631 and silc_client_send_private_message functions. Affected file
5634 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Redefined the Private Message Payload to support private message
5637 keys and to support the new private message flags. Updated
5638 the protocol specs. Flags makes it possible to have for example
5639 CTCP style messages.
5641 * Added new type SilcPrivateMessagePayload and defined an API
5642 for it in the lib/silcclient/silcprivate.[ch].
5644 * Tested private message private keys successfully. Tested the
5645 private message key set, unset and list commands with the new
5648 * Redefined the Channel Message Payload to include the channel
5649 message flags (equal with private message flags) to support
5650 for example CTCP style messages.
5652 * Defined some of the message (for channel and private message)
5653 flags. Updated the protocol specs and added the flags to the
5654 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5656 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added SilcKeyAgreementStatus type to the key agreement routines
5659 to indicate the current status and error if one occured.
5660 The status types are defined in the lib/silcclient/silcapi.h.
5662 * Added new local command KEY that is used to set and unset private
5663 keys for channels, set and unset private keys for private messages
5664 with remote clients and to send key agreement requests and
5665 negotiate the key agreement protocol with remote client. The
5666 key agreement is supported only to negotiate private message keys,
5667 it currently cannot be used to negotiate private keys for channels,
5668 as it is not convenient for that purpose.
5670 * Fixed a minor pending callback setting bug in the function
5671 silc_client_get_client_by_id_resolve, now the function works.
5672 Affected file lib/silcclient/idlist.c.
5674 * Added function silc_net_get_local_port to get local bound
5675 port by socket. Added to lib/silcutil/silcnet.[ch].
5677 * Added `sockets' and `sockets_count' fields to the SilcClient
5678 object. They hold the sockets of the listenning sockets in
5679 the client. Listenning sockets may be for example the key
5680 agreement server. Affected file lib/silcclient/client.[ch].
5681 Added functions the silc_client_add_socket and the
5682 silc_client_del_socket. They are exported to the application
5685 * Added ~./silc/clientkeys to support other client's public keys.
5687 * Renamed verify_server_key client operation to verify_public_key
5688 and added one argument to indicate the type of the connection
5689 (server, client etc.).
5691 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added silc_server_connection_auth_request to handle the
5694 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5695 silcd/packet_receive.[ch].
5697 * Added silc_server_send_connection_auth_request into the
5698 silcd/packet_send.c to send the connection auth request packet.
5700 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5703 * Fixed the public key authentication in responder side in the
5704 server. The `auth_data' pointer includes the SilcPublicKey
5705 not the path to the public key. Affected file silcd/protocol.c.
5707 * Implemented the public key authentication in the initiator side
5708 in the server. Affected file silcd/protocol.c.
5710 * Removed the [RedirectClient] config section from the server
5711 configuration. Is not needed and I don't want to implement it.
5713 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Cleaned up the CMODE command in the server. It now works
5716 correctly and supports all the modes defined in the protocol.
5717 Affected file is silcd/command.c.
5719 * Added `hmac_name' field to the SilcChannelEntry in the server
5720 to hold the default HMAC of the channel. It can be set when
5721 creating the channel (with JOIN command). Affected files
5724 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5725 type to indicate the change of the current cipher and hmac
5726 on the channel. Client can safely ignore the <cipher> argument
5727 (if it chooses to do so) since the CHANNEL_KEY packet will
5728 force the channel key change anyway. The <hmac> argument is
5729 important since the client is responsible of setting the new
5730 HMAC and the hmac key into use.
5732 * Fixed the CMODE command in the client library as well.
5734 * Tested CMODE command in router environment successfully.
5736 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Show the version of the remote client (or server) when connecting
5739 to the server. It is logged to the log file. Affected file
5740 is silcd/protocol.c.
5742 * Fixed the KILLED notify handling in the client library. The
5743 client must be removed from all channels when receiving the
5746 Also, do not remove the client entry when giving the KILL
5747 command but when the KILLED notify is received.
5749 * Removed silc_idlist_find_client_by_nickname from the server.
5750 Not needed anymore. Affected files silcd/idlist.[ch].
5752 * Implemented the CHANNEL_CHANGE notify type handling to the
5753 server. Affected file silcd/server.c.
5757 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Added silc_server_send_notify_invite to send the INVITE
5760 notify between routers.
5762 * Implemented the INVITE command correctly to the server.
5764 * Implemented the INVITE notify type handling in the server.
5766 * Implemented the INVITE command to the client library and on the
5769 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added function silc_server_get_client_resolve to find the
5772 client entry by ID from all ID lists and then resolve it
5773 (using WHOIS) if it cannot be found. Affected file is
5776 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Implemented the BAN command to the client library.
5780 * The JOIN command in the server now checks the invite list
5783 * Changed the silc_command_reply_payload_encode_va and the
5784 silc_command_payload_encode_va to support that if argument is
5785 NULL it ignores and checks the next argument. Affected file
5786 lib/silccore/silccommand.c.
5788 * Added silc_server_send_notify_ban to send the BAN notify
5789 type between routers.
5791 * Chaned the silc_notify_payload_encode to support that if
5792 argument is NULL it ignores and checks the next argument.
5793 Affected file lib/silccore/silcnotify.c.
5795 * Tested ban lists in router environment successfully.
5797 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Implemented BAN command to the server, in silcd/command.[ch].
5801 * Removed the BAN and INVITE_LIST modes from the CMODE command
5804 * Added function silc_string_match to regex match two strings.
5805 Affected files lib/silcutil/silcutil.[ch].
5807 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Redefined parts of the SilcChannelEntry in the server to support
5810 the new ban and invite lists.
5812 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Redefined the INVITE command. The same command can be used to
5815 invite individuals to the channel but also to manage the invite
5816 list of the channel (to add to and remove from the invite list).
5817 Updated the protocol specs.
5819 * Added new command SILC_COMMAND_BAN that can be used to manage
5820 the ban list of the channel. Updated the protocol specs.
5822 * Removed the channel modes: the SILC_CMODE_BAN and the
5823 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5824 in the CMODE command. The equivalent features are now available
5825 using INVITE and BAN commands. Updated the protocol specs.
5827 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5828 in the network about change in the current ban list. The notify
5829 type is not used by the client.
5831 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5832 support the invite lists.
5834 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Added new function silc_string_regexify that converts string
5837 including wildcard characters into regex string that can
5838 be used by the GNU regex library. Added into the file
5839 lib/silcutil/silcutil.[ch].
5841 Added silc_string_regex_combine to combine to regex strings
5842 into one so that they can be used as one regex string by
5843 the GNU regex library. Added into the file
5844 lib/silcutil/silcutil.[ch].
5846 Added silc_string_regex_match to match two strings. It returns
5847 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5849 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Imported GNU regex to the soruce tree into lib/contrib.
5852 Fixed some compiler warning from the regex.c.
5854 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Fixed MOTD command in the server to work in router environment.
5858 * Fixed the MOTD command in the client library to support
5859 the server argument in the command.
5861 * Added `nickname_len' argument to the silc_idlist_add_client
5862 in the server, as the `nickname' argument may be binary data
5865 * Added silc_idlist_get_channels to return all channels from
5868 * Implemented LIST command to the server. Affected file is
5871 * Implemented the LIST command to the client library and on the
5874 * Added [<user count>] argument to the LIST command reply.
5875 With private channels the user count is not shown.
5877 * Updated TODO and README.
5879 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * The client entry's data.registered must be TRUE even with
5882 global client entry on global client list. The data.registered
5883 is used to check whether the client is anymore in the network,
5884 for example with WHOWAS command so it must be valid.
5886 * Fixed the WHOWAS command in the server. It now actually works
5887 in router environment. Added function into silcd/command_reply.c
5888 silc_server_command_reply_whowas_save.
5890 * Added silc_idlist_purge function to the silcd/idlist.c
5891 to periodically purge the ID Cache.
5893 * Fixed INFO command in the server. It works now in router
5894 environment. Added <server name> argument to the INFO command
5895 reply. Updated the protocol specs.
5897 * Fixed minor bug in silc_idcache_purge to not purge if the
5898 expire value is zero.
5900 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5901 they were buggy because of the WHOWAS information.
5903 * Fixed local command MSG to handle the async resolving of
5904 the remote client properly. It used to fail the first MSG.
5905 Affected file silc/local_command.c.
5907 * Added `data_len' field to SilcIDCache context.
5909 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Update TODO. Todo in commands in the server.
5913 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5916 used by routers as broadcast packet to inform other routers
5917 about the changed user mode.
5919 Implemented the notify handling in the server. Affected file is
5920 silcd/packet_receive.c. Added the function
5921 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5923 * Added new generic Channel Payload and deprecated the New Channel
5924 Payload. The New Channel Payload is now the generic Channel
5927 * Added new argument `mode' to the silc_server_send_new_channel
5928 as it is required in the Channel Payload now.
5930 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5931 and created a new and real SilChannelPayload to represent the
5932 new generic Channel Payload. Implemented the encode/decode
5933 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5935 * Added silc_server_get_client_channel_list to return the list
5936 of channels the client has joined for WHOIS command reply.
5937 Affected file silcd/server.[ch].
5939 * Implemented the channel list sending in the WHOIS command reply
5940 in server and in the client.
5942 Implemented the channel list displaying on the user interface
5943 as well. Affected file silc/client_ops.c.
5945 * Added silc_channel_payload_parse_list to parse list of Channel
5946 Payloads. It returns SilcDList list of SilcChannelPayloads.
5947 Client for example can use this function to parse the list of
5948 channels it receives in the WHOIS command reply. The caller
5949 must free the list by calling silc_channel_payload_list_free.
5950 Affected files lib/silccore/silcchannel.[ch].
5952 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added one new argument <user mode> to the WHOIS command reply
5955 to return the mode of the user in SILC. Updated the protocol
5958 Implemented it to the server and client.
5960 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Fixed the mode printing on the user interface on joining.
5963 Affected file silc/client_ops.c.
5965 * Implemented the UMODE command and user modes in general to the
5966 client library and to the user interface.
5968 * Implemented the UMODE command to the server.
5970 * The server now sends UNKNOWN_COMMAND error status if client sends
5971 unknown command. Affected file silcd/command.c.
5973 * All server commands now handle the command identifier the right
5974 way when sending the command reply to the client. The client can
5975 use to identify the command replies with the identifier.
5977 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Added silc_server_get_client_route to resolve the route to
5980 the client indicated by the client ID. Affected file is
5983 * Added silc_server_relay_packet as general function to relay
5984 packet to arbitrary destination. This deprecates functions
5985 like _send_private_message_key, _relay_notify etc. Affected
5986 file is silcd/packet_send.[ch].
5988 Removed silc_server_send_key_agreement,
5989 silc_server_send_private_message_key and
5990 silc_server_packet_relay_notify functions from the file
5991 silcd/packet_send.[ch].
5995 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5996 server. Affected file silcd/packet_receive.[ch].
5998 * Implemented the KILL command to the client. Implemented the
5999 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6000 Affected files lib/silcclient/command[_reply].c and
6001 lib/silcclient/client_notify.c. Implemented the KILL notify
6002 printing in the user inteface.
6004 * Fixed a lot silc_parse_nick memory leaks from the client
6005 library in the file lib/silcclient/command.c.
6007 * Changed the silc_server_send_notify_on_channels's `sender'
6008 argument from SilcSocketConnection to SilcClientEntry to
6009 check the sender as entry and not as connection object and not
6010 to send to the client provided as argument. The affected file
6011 is silcd/packet_send.[ch].
6013 * The notify packets that are destined directly to the client used
6014 to not to be processed by the server. Now changed that and the
6015 server processes all notify packets. After relaying the packet
6016 to the client the notify packet is processed in the server.
6018 * The silc_server_free_client_data now checks whether there is
6019 pending outgoing traffic for the client and purges the data to
6020 the network before removing the client entry.
6022 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6025 an client is killed from the SILC Network. Updated the protocol
6028 Added new function silc_server_send_notify_killed to the
6029 silcd/packet_send.[ch].
6031 * Added function silc_server_packet_relay_notify to relay notify
6032 packets that are destined directly to a client. In this case
6033 the server does not process the notify packets but merely relays
6034 it to the client. Affected file silcd/packet_send.[ch].
6036 Added also silc_server_packet_process_relay_notify to check
6037 whereto relay the notify. Affected file is
6038 silcd/packet_receive.[ch].
6040 * Implemented the KILL command to the server.
6044 * Added the backup schema desgined last fall to the protocol
6045 specs for everyone to see. The specification is in the
6046 *-spec-xx.txt draft and the packet type definitions for the
6047 backup routers is in *-pp-xx.txt draft. Thusly, added also
6048 new packet type SILC_PACKET_CELL_ROUTERS.
6050 * A big security problem in the implementation discovered. The
6051 signoff of an client did not cause new channel key generation
6052 which it of course should've done. The channel keys must be
6053 always re-generated when client leaves (or signoffs) the channel.
6054 The silc_server_remove_from_channels funtion now handles
6055 the channel key re-generation.
6057 * Added `sender' argument to the silc_server_send_notify_on_channels
6058 to not to send the client provided as argument. Affected file
6059 silcd/packet_send.[ch].
6061 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Implemented OPER and SILCOPER commands into the server and
6066 * Added silc_auth_verify and silc_auth_verify_data to verify
6067 the authentication directly from the authentication payload.
6068 It supports verifying both passphrase and public key based
6069 authentication. Affected file lib/silccore/silcauth.[ch].
6071 * Added `hash' field to the SilcIDListData structure. It is the
6072 hash negotiated in the SKE protocol. Affected file is
6075 * Slight redesigning of the SilcAuthPayload handling routines.
6076 Do not send SilcPKCS but SilcPublicKey as argument.
6078 * Implemented the public key authentication support to the
6079 serverconfig. The public key is loaded from the provided path
6080 and saved as authentication data to void * pointer. Thus,
6081 changed the unsigned char *auth_data to void *auth_data;
6083 * Fixed SHUTDOWN command to send the reply before the server
6084 is shutdown. :) Affected file silcd/command.c.
6086 * Fixed fatal bug in CONNECT command. The hostname was invalid
6087 memory and server crashed. Affected file silcd/command.c.
6089 * Fixed fatal bug in CLOSE command. The server_entry became
6090 invalid but was referenced later in the command. Affected file
6093 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Fixed fatal bug in failure packet handling. Server ignored
6096 the failure and thus crashed when it came.
6100 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6103 that the command may be executed only once in (about) 2 seconds.
6104 The old SILC_CF_LAG flag is same but allows command bursts up
6105 to five before limiting.
6107 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6108 server code. Various commands now includes the CF_LAG_STRICT
6109 flag to disallow any kind of miss-use of the command.
6111 * Fixed the silc_buffer_unformat to not to allocate any data
6112 if the length of the data is zero. It used to allocate the
6113 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6115 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Changed the format of AdminConnection configuration section
6118 in the server. Added username of the admin to the format.
6119 Affected files silcd/serverconfig.[ch].
6121 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6122 to return admin configuration data by host, username and/or
6125 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Implemented WHOWAS command to the server. Added the functions:
6129 silc_server_command_whowas_parse,
6130 silc_server_command_whowas_send_reply,
6131 silc_server_command_whowas_from_client and
6132 silc_server_command_whowas_from_server
6134 * Added <Client ID> argument to the WHOWAS command reply. Updated
6135 the protocol specs accordingly.
6137 * Implemented WHOWAS command and command_reply to the client
6140 Implemented the WHOWAS printing on the user interface.
6142 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added new argument to the WHOWAS command reply, the real name.
6145 It is an optional argument. Updated the protocol specs.
6147 * Added SilcIDCacheDestructor callback that is registered when
6148 the SilcIDCache is allocated. The callback is called when
6149 an cache entry in the ID Cache expires, or is purged from the
6150 cache. Added into lib/silccore/idcache.[ch].
6152 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6153 to destruct the client entries when the cache entry expires.
6154 Other ID Cache's in server and in the client library ignores
6157 * If the ID Cache entry's `expire' field is zero then the entry
6158 never expires. Added boolean `expire' argument to the
6159 silc_idcache_add function in the lib/silccore/idcache.[ch].
6160 If it is TRUE the default expiry value is used.
6162 * Added silc_server_free_client_data_timeout that is registered
6163 when client disconnects. By default for 5 minutes we preserve
6164 the client entry for history - for WHOWAS command.
6166 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Added support to the server to enforce that commands are not
6169 executed more than once in 2 seconds. If server receives
6170 commands from client more frequently, timeout is registered
6171 to process the commands. Affected file silcd/command.c.
6172 Added new function silc_server_command_process_timeout.
6174 * Changed NICK_NOTIFY handling in client library to check that
6175 if the client's nickname was changed, so there is no need to
6176 resolve anything from the server.
6178 * Removed error printing from the WHOIS and IDENTIFY commands.
6179 If error occurs then it is ignored silently in the client library.
6180 The application, however, may map the received error to
6181 human readable error string. The application currently maps
6182 the NO_SUCH_NICKNAME error to string.
6184 * Made the command status message public to the application. Moved
6185 them from lib/silcclient/command_reply.c to
6186 lib/silcclient/command_reply.h. The application can map the
6187 received command status to the string with the
6188 silc_client_command_status_message function.
6190 * Added check to the server to check that client's ID is same
6191 as the Source ID in the packet the client sent. They must
6194 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added dist-bzip hook to the Makefile.am to make bzip2
6197 compressed distributions.
6199 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6201 * Server now enforces the maximum length for the nickname and
6202 the channel as protocol specification dictates. 128 bytes for
6203 nickname and 256 bytes for channel name.
6205 * Moved the WHOIS printing to the application. The client libary
6206 does not print out the WHOIS information anymore, the application
6207 must do it. Renamed silc_client_command_reply_whois_print to
6208 the silc_client_command_reply_whois_save.
6210 The client's idle time is also sent to the application now, and
6211 the idle is shown on screen.
6213 * Added silc_client_command_reply_identify_save to save the
6214 received IDENTIFY entries.
6216 * Do not check for channel private keys in message sending and
6217 reception if the channel does not have the PRIVKEY mode set.
6218 Affected file lib/silclient/client_channel.c.
6220 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6223 just surfaced after chaning the JOIN procedure.
6225 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added silc_client_get_clients_by_list to get client entries
6228 from Client ID list, that is returned for example by JOIN
6229 and USERS command replies. The application should use this
6230 function for example when JOIN command reply is received to
6231 resolve the clients already on the channel (library does not
6232 do that anymore as USERS command reply is not used in the JOIN
6233 procedure anymore). Affected files lib/silcclient/silcapi.h and
6234 lib/silcclient/idlist.c.
6236 * JOIN command reply and USERS command reply returns now SilcBuffer
6237 pointers instead of unsigned char pointers when returning
6238 the client list and mode list.
6240 * Added <Client ID> argument to the JOIN command reply, mainly
6241 for the server to identify for which client the command was
6242 originally sent. Updated protocol specs accordingly.
6244 * Added SilcDlist private_key pointer to the SilcChannelEntry
6245 in the client to support the channel private keys. Affected
6246 file is lib/silcclient/idlist.h.
6248 * Added SilcChannelPrivateKey argument to the function
6249 silc_client_send_channel_message so that application can choose
6250 to use specific private ke if it wants to. If it is not provided,
6251 the normal channel key is used, unless private keys are set.
6252 In this case the first (key that was added first) is used
6253 as the encryption key.
6255 * Implemented the support for channel private key handling.
6256 Implemented the following functions:
6258 silc_client_add_channel_private_key,
6259 silc_client_del_channel_private_keys,
6260 silc_client_del_channel_private_key,
6261 silc_client_list_channel_private_keys and
6262 silc_client_free_channel_private_keys
6264 Affected file lib/silcclient/client_channel.c.
6266 * Added the support for the private keys in the channel message
6267 sending and encryption and in the message reception and
6268 decryption. Affected funtions are
6269 silc_client_send_channel_message and silc_client_channel_message.
6271 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Added SKE's key verify callback to the client library's
6274 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6276 * Removed the statement that server (or router) must send USERS
6277 command reply when joining to the channel so that the client
6278 knows who are on the channel. Instead, the client list and
6279 client's mode list is now sent in the JOIN command reply to the
6280 client who joined channel. This is better solution.
6282 * Added function silc_server_get_users_on_channel and function
6283 silc_server_save_users_on_channel to the silcd/server.[ch].
6285 * Removed function silc_server_command_send_users from the
6288 * Do not show topic on the client library anymore. The topic is
6289 sent in the command reply notify to the application and the
6290 application must show the topic now.
6292 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Added client searching by nickname hash into the IDENTIFY and
6295 WHOIS commands in the server as they were clearly missing from
6296 them. Affected file is silcd/command.c.
6298 * Fixed a bug in private message receiving in the client library.
6299 The remote ID was freed and it wasn't supposed, now it is
6302 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Minor fix to the channel payload; allocate the data area, as it
6305 needs to be of specific length.
6307 * If the key agreement port is zero then the operating
6308 system will define the bound port. Affected files are
6309 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6311 * Added new function silc_channel_payload_decrypt into the file
6312 lib/silccore/silcchannel.[ch].
6314 * Moved the channel message etc, check from silc_packet_decrypt
6315 to applications. The library calls now a generic
6316 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6317 when the packet is either normal or special. This was done to
6318 allow more wide range of checking that was not allowed when
6319 the code was in library. Now applications can do virtually any
6320 checks to the packet and return to the library the decision how
6321 the packet should be processed. Affected files are
6322 lib/silccore/silcpacket.[ch].
6324 Added silc_server_packet_decrypt_check to the server and
6325 silc_client_packet_decrypt_check to the client library.
6327 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6328 to send with specified source and destination information.
6330 * Channel message delivery between routers was broken after the
6331 channel key distribution was fixed earlier. The channel key
6332 was used be to distributed to other routers as well which is not
6333 allowed by the protocol. Now this is fixed and channel keys
6334 really are cell specific and the channel message delivery between
6335 routers comply with the protocol specification.
6337 * Fixed various commands in server to check also the global list
6338 for the channel entry and not just the local list. The affected
6339 file silcd/command.c.
6341 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Added assert()s to buffer formatting and unformatting routines
6344 to assert (if --enable-debug) when error occurs. Affected
6345 file: lib/silcutil/silcbuffmt.c.
6347 * Changed to auto-reconnect to check whether the remote host is
6348 router and register the re-connect timeout if it is. It used
6349 to check that whether we are normal server, but router must do
6350 auto-reconnect with another router as well. Affected file
6353 * Removed the [<key len>] option from CMODE command as the cipher
6354 name decides the key length, nowadays. See the defined ciphers
6355 from the protocol specification.
6357 * Added [<hmac>] option to the CMODE command to define the HMAC
6358 for the channel. Added SILC_CMODE_HMAC channel mode.
6360 * Added [<hmac>] option for the JOIN command so that user can
6361 select which HMAC is used to compute the MACs of the channel
6364 * Added Hmac field to the Channel Message Payload. The integrity
6365 of plaintext channel messages are now protected by computing
6366 MAC of the message and attaching the MAC to the payload. The
6367 MAC is encrypted. Now, it is clear that this causes some
6368 overhead to the size of the packet but rationale for this is that
6369 now the receiver can verify whether the channel message decrypted
6370 correctly and also when private keys are set for the channel the
6371 receiver can decrypt the packet with several keys and check from
6372 the MAC which key decrypted the message correctly.
6374 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6375 lib/silccrypt/silccipher.[ch].
6377 * Added silc_hash_len to return the digest length into the
6378 lib/silcrypt/silchash.[ch].
6380 * Rewrote parts of Silc Channel Payload interface in the
6381 lib/silccore/silcchannel.[ch]. The encode function now also
6382 encrypts the packet and parse function decrypts it.
6384 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * Fixed a minor formatting bug in the SKE's key material processing.
6387 It actually might have processed the keys wrong way resulting
6390 * Redefined the mandatory HMAC algorithms and added new algorithms.
6391 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6392 and hmac-md5 truncated to 96 bits. The mandatory is now
6393 hmac-sha1-96. Rest are optional (including the one that used
6394 to be mandatory). Rationale for this is that the truncated HMAC
6395 length is sufficient from security point of view and can actually
6396 make the attack against the HMAC harder. Also, the truncated
6397 HMAC causes less overhead to the packets. See the RFC2104 for
6400 * Added new [hmac] configuration section. The SKE used to use
6401 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6402 is of course wrong. The official names that must be proposed in
6403 the SKE are the ones defined in the protocol specification
6404 (hmac-sha1-96 for example). The user can configure any hmac
6405 using any hash function configured in the [hash] section. At
6406 least, the mandatory must be configured.
6408 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6410 * Added HMAC list to the SKE proposal list. It has now both
6411 hash algorithm list and HMAC list. This makes the protocol
6412 incompatible with previous versions. The SKE now seems to work
6413 the way it is supposed to work, for the first time actually.
6415 * Defined plain Hash algorithms to the protocol specification.
6418 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Implemented support for key agreement packets into the server.
6421 Added functions silc_server_key_agreement and
6422 silc_server_send_key_agreement. Other than these functions,
6423 server has nothing to do with this packet.
6425 * Added support for private message key packets into the server.
6426 Added functions silc_server_private_message_key and
6427 silc_server_send_private_message_key.
6431 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6432 called in the protocol's final callback instead in the END
6433 protocol state. This makes a little more sense and in the same
6434 time in client we can use the same protocol routines for normal
6435 key exchange and to key agreement packet handling as well.
6437 * Added to both client's and server's KE protocol context the
6438 SilcSKEKeyMaterial pointer to save the key material. We will
6439 bring the key material to the protocol's final callback by doing
6440 this. The final callback must free the key material.
6442 * Added SKE's packet_send callback into client's KE protocol
6443 context so that the caller can choose what packet sending function
6444 is used. This way we can use different packet sending when
6445 doing normal SKE when doing key agreement packet handling (in
6446 the key agreement packet handling we do not want to encrypt
6449 * Implemented the responder side of the key agreement routines
6450 in the client. The client can now bind to specified port and
6451 accept incoming key negotiation. The key material is passed
6452 to the application after the protocol is over.
6454 * Implemented the processing of incoming Key Agreement packet
6455 in the client. Added function silc_client_key_agreement to
6458 * Implemented the intiator side of the key agreement routines
6459 in the client. The client can now initiate key agreement with
6460 another remote client. The key material is passed to the
6461 application after the protocol is over.
6463 * Created client_keyagr.c to include all the key agreement
6466 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6467 SILC_TASK_CALLBACK except that it is not static.
6469 * Created client_notify.c and moved the Notify packet handling
6470 from the client.[ch] into that file.
6472 * Created client_prvmsg.c and moved all private message and
6473 private message key routines from the client.[ch] into that file.
6475 * Create client_channel.c and moved all channel message and
6476 channel private key routines from the client.[ch] into that file.
6478 * Changed silc_client_get_client_by_id_resolve to resolve with
6479 WHOIS command instead of IDENTIFY command, in the file
6480 lib/silclient/idlist.c.
6482 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Implemented the SKE's responder side to the Client library.
6486 * When FAILURE is received to the protocol do not trust it
6487 blindly. Register a timeout to wait whether the remote closes
6488 the connection as it should do it, only after that process the
6489 actual failure. This was changed to both client and server.
6491 * Added client_internal.h to include some of the structures
6492 there instead of client.h in lib/silcclient/.
6494 * Added function silc_task_unregister_by_callback to unregister
6495 timeouts by the callback function.
6497 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6499 * Some "Incomplete WHOIS info" errors has been appearing on the
6500 log files. Took away the entry->userinfo check from WHOIS
6501 reply sending. The entry->userinfo is now " " if client did not
6502 provide one. I thought this was fixed earlier but something
6503 is wrong still. Let's see if the error still appears.
6505 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Fixed a minor bug in the login when the channel key is
6508 re-generated in the server. It used to generate the key in
6509 wrong order and thus caused problems in the channel traffic.
6511 * Fixed a minor bug in channel key distsribution after
6512 KICK command. The key was not sent to the router even though
6515 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Added silc_ske_process_key_material_data as generic routine
6518 to process any key material as the SILC protocol dictates. The
6519 function is used by the actual SKE library but can be used by
6520 applications as well. This relates to the private message keys
6521 and the channel private keys since they must be processed the
6522 same way the normal SILC session keys. The protocol dictates
6523 this. Affected files: lib/silcske/silcske.[ch].
6525 Added also silc_ske_free_key_material to free the
6526 SilcSKEKeyMaterial structure.
6528 * Defined silc_cipher_set_key function to set the key for
6529 cipher without using the object's method function. The affected
6530 files: lib/silccrypt/silccipher.[ch].
6532 * Implemented silc silc_client_add_private_message_key,
6533 silc_client_add_private_message_key_ske,
6534 silc_client_del_private_message_key,
6535 silc_client_list_private_message_keys and
6536 silc_client_free_private_message_keys functions in the
6539 Added functions silc_client_send_private_message_key to send
6540 the Private Message Key payload and silc_client_private_message_key
6541 to handle incoming Private Message Key payload.
6543 * Added Cipher field to the Private Message Key payload to set
6544 the cipher to be used. If ignored, the default cipher defined
6545 in the SILC protocol (aes-256-cbc) is used.
6547 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Removed lib/silcclient/ops.h file.
6551 Redefined parts of the SILC Client Library API. Created new
6552 file silcapi.h that deprecates the ops.h file and defines the
6553 published Client Library API. Defined also private message key
6554 API and channel private key API into the file.
6556 This is the file that the application must include from the
6557 SILC Client Library. Other files need not be included by
6558 the application anymore.
6560 * Added new key_agreement client operation callback and also
6561 defined the Key Agreement library API for the application.
6563 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6566 is used by clients to request key negotiation between another
6567 client in the SILC network. If the negotiation is started it
6568 is performed using the SKE protocol. The result of the
6569 negotiation, the secret key material, can be used for example
6570 as private message key.
6572 Implemented the Key Agreement payload into the files
6573 lib/silccore/silauth.[ch].
6575 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Redefined ciphers for the SILC protocol. Added some new ciphers
6578 and defined the key lengths for the algorithms. Changed the
6579 code accordingly. The default key length is now 256 bits.
6581 * Fixed SKE key distribution function silc_ske_process_key_material
6582 when the key length is more than 128 bits. The default key
6583 length in SILC is now 256 bits.
6585 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6586 to indicate unsupported algorithm.
6588 * Renamed rijndael.c to aes.c and all functions as well.
6590 * Fixed a long standing channel key setting bug in client library.
6591 Weird that it has never surfaced before.
6593 * Fixed bug in channel deletion. If the entire channel is removed
6594 then it must also delete the references of the channel entry
6595 from the client's channel list as the client's channel entry and
6596 the channel's client entry share same memory.
6598 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Implemented CONNECT and SHUTDOWN commands in the client.
6602 * Implemented CLOSE command to the client.
6604 * Added the function silc_idlist_find_server_by_name into the
6605 files silcd/idlist.[ch].
6607 Added the function silc_idlist_find_server_by_conn into the
6608 files silcd/idlist.[ch].
6610 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * DIE command was renamed to SHUTDOWN. Updated the both code
6615 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6616 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6618 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6621 * Added function silc_server_create_connection function to create
6622 connection to remote router. My server implementation actually
6623 does not allow router to connect to normal server (it expects
6624 that normal server always initiates the connection to the router)
6625 so the CONNECT command is only good for connecting to another
6628 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6631 or some other client was kicked from the channel.
6633 Implemented the handling of the notify type to both client
6636 Implemented silc_server_send_notify_kicked to send the KICKED
6637 notify. It is used to send it to the server's primary router.
6639 * Implemented the KICK command into server and client.
6641 * Added `query' argument to the silc_idlist_get_client function
6642 to indicate whether to query the client from server or not if
6645 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6646 to indicate that the client is not channel founder.
6650 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Removed the rng context from SilcPacketContext structure and
6653 changed that the packet routine uses the Global RNG API.
6655 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6657 * Added support for quit message that client can "leave" on the
6658 channel when it quits the SILC. It is ditributed inside the
6659 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6661 Added silc_server_free_client_data that will take the
6662 signoff message as argument.
6664 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6666 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Updated parts of the protocol specification to keep it up
6671 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6674 payloads in one packet.
6676 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6677 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6678 use now the new List flag.
6680 * Also deprecated the following packet types: REPLACE_ID,
6681 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6683 * Added list support for Notify packet in server.
6685 * Added silc_server_send_notify_channel_change to send the
6686 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6687 the silc_server_send_replace_id.
6689 * Added silc_server_send_notify_nick_change to send the
6690 NICK_CHANGE notify type. Deprecates the function
6691 silc_server_send_replace_id.
6693 * Added silc_server_send_notify_join to send the JOIN notify type.
6694 Deprecates the function silc_server_send_new_channel_user.
6696 * Added silc_server_send_notify_leave to send LEAVE notify type.
6697 Deprecates the function silc_server_send_remove_channel_user.
6699 * Added silc_server_send_notify_cmode and
6700 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6701 types. Deprecates the silc_server_send_set_mode function.
6703 * Added SERVER_SIGNOFF notify type to indicate that server has
6704 quit. This means that all clients on the channel from that
6705 server will drop. This can be also used when netsplit happens.
6707 Deprecated REMOVE_ID packet type since it is not needed anymore
6710 Added silc_server_send_notify_server_signoff to send the
6711 SERVER_SIGNOFF notify type. Deprecates the function
6712 silc_server_send_remove_id.
6714 Added also silc_server_send_notify_signoff to send the
6715 SIGNOFF notify type.
6717 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6718 SILC protocol from this day on. Changed the protocol
6719 specification as well.
6721 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6722 notify type. It is used between routers to notify about
6723 topic changes on a channel.
6725 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6728 * Partly updated the protocol specification to comply with the
6729 changes now made. It is still though a bit outdated.
6731 * The JOIN notify type now takes one extra argument <Channel ID>.
6732 The packet used to be destined to the channel but now the
6733 JOIN type may be sent as list thus it is impossible to
6734 destine it to any specific channel. By adding this argument
6735 it is again possible.
6737 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Added CREDITS file. The CHANGES and CREDITS file will appear
6740 in the distribution as well.
6742 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6745 types in the server's silcd/packet_receive.c.
6747 * Implemented CMODE and CUMODE to work in router environment.
6749 * Fixed minor encoding and decoding buglet from the
6750 lib/silccore/silcmode.c.
6752 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6755 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6757 * Changed all SilcConfigServer* and silc_config_server* to
6758 SilcServerConfig* and silc_server_config*, respectively.
6761 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Associated the ID (client or server ID) to the Authentication
6764 Payload to avoid any possibility of forging. Updated the
6765 protocol specification and the code accordingly.
6767 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * The RSA key length is now save to the RsaKey context in the
6770 key generation process in lib/silccrypt/rsa.c. The key length
6771 is now used to figure out the maximum size of the block allowed
6772 to be encrypted/signed.
6774 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6775 is equivalent to the silc_mp_mp2bin but does not allocate any
6778 * Changed silc_mp_mp2bin API to take length argument. If it is
6779 non-zero then the buffer is allocated that large. If zero, then
6780 the size is approximated using silc_mp_sizeinbase, which however
6783 * Created Global RNG API which is global RNG that application can
6784 initialize. After initializing, any routine anywhere in the
6785 code (including library) can use RNG without allocating a new
6786 RNG object. This was done to allow this sort of use of the
6787 RNG in code that has no chance to allocate RNG object. All
6788 applications currently allocate this and many routines in the
6789 library use this. Affected file lib/silccrypt/silcrng.[ch].
6791 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6792 it to use the Global RNG API.
6794 * Defined Authentication Payload into protocol specification that
6795 is used during SILC session to authenticate entities. It is
6796 used for example by client to authenticate itself to the server
6797 to obtain server operator privileges.
6799 Implemented this payload into the lib/silccore/silcauth.[ch].
6800 Implemented also routines for public key based authentication
6801 as the new protocol specification dictates.
6803 Moved definitions of different authentication methods from
6804 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6806 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6807 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6808 silc_pkcs_verify_with_hash functions into the file
6809 lib/silccrypt/silcpkcs.[ch].
6811 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * The client entry's userinfo pointer must be always valid.
6814 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6815 will fail since it requires the userinfo. Now, the userinfo
6816 is allocated as "" if actual userinfo does not exist. Actually,
6817 it must exist and it is totally Ok to drop client connections
6818 that does not announce the userinfo. However, we will make
6819 this workaround for now.
6821 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6822 to return the remote port by socket.
6824 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6827 SILC_SERVER_PENDING_EXEC and added an new macro
6828 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6829 data or when error occurs while processing the pending command.
6831 Added new argument `destructor' into silc_server_command_pending
6832 and to the SilcServerCommandPending object. This destructor is
6833 now called after calling the pending callback or if error occurs
6834 immediately. If error occurs the actual pending callback won't
6835 be called at all - only the destructor. The destructor may be
6836 NULL if destructor is not needed.
6838 All this applies for client library code as well. Similar
6839 changes were made there as well for the pending commands.
6841 In the client, the application must now allocate the
6842 SilcClientCommandContext with the silc_client_command_alloc
6845 * Added reference counter to the SilcServerCommandContext. Added
6846 function silc_server_command_alloc and silc_server_command_dup
6849 Same type of functions added to the client library for the same
6852 * Removed the cmd_ident from IDListData away since it is now
6853 global for all connections. It is the command identifier used
6854 in command sending and with pending commands. The affected file
6857 * Added reference counter to the SilcSocketConnection objecet to
6858 indicate the usage count of the object. The object won't be
6859 freed untill the reference counter hits zero. Currently only
6860 server uses this, and client ignores it. The client must be
6861 set to use this too later. The affected files are
6862 lib/silccore/silcsockconn.[ch]. Added also the function
6863 silc_socket_dup to increase the reference counter.
6865 This was mainly added because it is possible that the socket
6866 is removed underneath of pending command or other async
6867 operation. Now it won't be free'd and proper DISCONNECTING
6868 flags, etc. can be set to avoid sending data to connection that
6869 is not valid anymore.
6871 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6872 the connection. After that it sets SILC_SET_DISCONNECTED.
6873 It is, however, possible that the socket data is not still freed.
6874 The silc_server_packet_process now checks that data is not
6875 read or written to connection that is DISCONNECTED. The socket
6876 get's freed when the reference counter hits zero.
6878 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6880 * Changed the client operation API: channel_message operation's
6881 `sender' is now the client entry of the sender, not the nickname
6882 and the `channel' is the channel entry, not the channel name.
6884 In the private_message operation the `sender' is now also the
6885 client entry of the sender not the nickname.
6887 Affected file is lib/silcclient/ops.h and all applications
6888 using the client operations.
6890 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Moved the calling of ops->connect() from connect_to_server_final
6893 into receive_new_id functin since that is the point when the
6894 client is actually allowed to send traffic to network. The
6895 affected file is lib/silcclient/client.c.
6897 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6900 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6901 (if needs broadcasting) instead of broadcasting the packets one
6902 by one which would make a burst in the network traffic.
6904 * Added `broadcast' argument to the functions in silcd/server.[ch]
6905 silc_server_create_new_channel[_with_id] to indicate whether
6906 to send New Channel packet to primary router.
6908 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added new function into the silcd/server.[ch] files:
6911 silc_server_create_new_channel_with_id to create new channel with
6912 already existing Channel ID.
6914 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6915 lib/silccore/silcpacket.h. This packet is used t send list of
6916 Set Mode payloads inside one packet. Server uses this to set
6917 the modes for the channels and clients on those channels, that it
6918 announced to the router when it connected to it. The protocol
6919 specification has been updated accordingly.
6921 * The silc_server_new_channel did not handle the packet coming
6922 from normal server as it normally does not send that. However,
6923 when it announces its channels it does send it. Implemented
6924 the support for that.
6926 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6927 into the file lib/silccore/id.h.
6929 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Fixed memory leaks in the functions silc_idlist_del_client,
6932 silc_idlist_del_channel and silc_idlist_del_server in the file
6933 silcd/idlist.c. All of those leaked like a sieve.
6935 * Fixed some small memory leaks in the client's function
6936 silc_client_notify_by_server.
6938 * Added functions into silcd/server.c: silc_server_announce_clients,
6939 silc_server_announce_channels and silc_server_announce_server.
6940 These functions are used by normal and router server to announce
6941 to its primary router about clients, channels and servers (when
6942 router) that we own. This is done after we've connected to the
6945 These functions effectively implements the following packet types:
6946 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6947 and SILC_PACKET_NEW_ID_LIST.
6949 * Added new functions into the silcd/packet_receive.[ch]:
6950 silc_server_new_id_list, silc_server_new_channel_list and
6951 silc_server_new_channel_user_list to handle the incoming
6952 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6954 * Added support of changing Channel ID in the function
6955 silc_server_replace_id. If the server that announces a channel
6956 to the router already exists in the router (with same name but
6957 with different Channel ID), router is responsible to send
6958 Replace ID packet to the server and force the server to change
6959 the Channel ID to the one router has.
6961 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6962 client that the Channel ID has been changed by the router. The
6963 normal server sends this to the client. Client must start using
6964 the new Channel ID as the channel's ID.
6966 Implemented handling of this new type into lib/silcclient/client.c
6967 into the function silc_client_notify_by_server.
6969 * Added new function silc_idlist_replace_channel_id into the files
6970 silcd/idlist.[ch] to replace the Channel ID.
6972 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6974 * Call silc_server_command_identify_check always when processing
6975 the IDENTIFY command in silcd/command.c
6977 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6980 send keepalive packets. The packet can be sent by clients,
6981 servers and routers.
6983 Added function silc_socket_set_heartbeat into the file
6984 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6985 If not set, the heartbeat is not performed. The actual
6986 heartbeat is implemented in the low level socket connection
6987 library. However, application is responsible of actually
6990 Added silc_server_send_heartbeat to send the actual heartbeat
6991 packet into silcd/packet_send.[ch]. Server now performs
6992 keepalive with all connections.
6994 * Added silc_task_get_first function into lib/silcutil/silctask.c
6995 to return the timeout task with shortest timeout. There was a bug
6996 in task unregistration that caused problems. TODO has been
6997 updated to include that task system must be rewritten.
6999 * The client library will now resolve the client information when
7000 receiving JOIN notify from server for client that we know but
7001 have incomplete information.
7003 * Rewrote parts of silc_server_remove_from_channels and
7004 silc_server_remove_from_one_channel as they did not remove the
7005 channel in some circumstances even though they should've.
7007 * Encryption problem encountered in server:
7009 The LEAVE command used to send the Channel Key packet to the
7010 router immediately after generating it. However, the code
7011 had earlier sent Remove Channel user packet but not immediately,
7012 ie. it was put to queue. The order of packets in the router
7013 was that Channel Key packet was first and Remove Channel User
7014 packet was second, even though they were encrypted in the
7015 reverse order. For this reason, MAC check failed. Now, this
7016 is fixed by not sending the Channel Key packet immediately but
7017 putting it to queue. However, this is more fundamental problem:
7018 packets that are in queue should actually not be encrypted
7019 because packets that are sent immediately gets encrypted
7020 actually with wrong IV (and thus MAC check fails). So, packets
7021 that are in queue should be encrypted when they are sent to
7022 the wire and not when they put to the queue.
7024 However, the problem is that the current system has not been
7025 designed to work that way. Instead, the packet is encrypted
7026 as soon as possible and left to the queue. The queue is then
7027 just purged into wire. There won't be any fixes for this
7028 any time soon. So, the current semantic for packet sending
7031 o If you send packet to remote host and do not force the send
7032 (the packet will be in queue) then all subsequent packets to the
7033 same remote host must also be put to the queue. Only after the
7034 queue has been purged is it safe again to force the packet
7037 o If you send all packets immediately then it safe to send
7038 any of subsequent packets through the queue, however, after
7039 the first packet is put to queue then any subsequent packets
7040 must also be put to the queue.
7042 Follow these rules and everything works fine.
7044 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7046 * Added new function silc_server_remove_clients_by_server to
7047 remove all client entries from ID list when the server connection
7048 is lost. In this case it is also important to invalidate all
7049 client entires as they hold the invalid server entry. This
7050 fixes fatal bug when server has lost connection and will reconnect
7053 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Made some sanity checks to silc_server_daemonise like to check
7056 whether the requested user and group actually exists.
7058 * Added sanity check to SKE's silc_ske_responder_finish to check
7059 that the public and private key actually is valid.
7061 * Invalidate the client's nickname when receiving Replace ID
7062 packet and the Client ID is being replaced. This means that the
7063 server will query the nickname if someone needs it (client)
7066 * Sort the ID Cache in client library when the ID Cache data
7067 has changed (needs sorting).
7069 * Do not allow for SILC client to create several connections to
7070 several servers. The client does not support windows right now
7071 and generating multiple connections causes weird behaviour.
7073 Irssi-silc client does support windows and can handle several
7074 connections without problems, see: www.irssi.org and SILC plugin.
7076 * Fixed some places where client was added to the IDList. The
7077 rule of thumb is following (in order to get everything right):
7078 If the client is directly connected local client then the
7079 `connection' argument must be set and `router' argument must be
7080 NULL to silc_idlist_add_client function. If the client is not
7081 directly connected client then the `router' argument must
7082 bet set and the `connection' argument must be NULL to the
7083 silc_idlist_add_client function.
7085 * The funtion silc_server_packet_send_local_channel actually did
7086 not check whether the client was locally connected or not. It
7087 does that now. Fixed a bug related to LEAVE command.
7089 * Fixed Remove Channel User payload parsing bug in server's
7090 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7092 * The server's silc_server_save_channel_key now checks also the
7093 global ID list for the channel as it might not be in the local
7094 list. Fixed a bug related to LEAVE command.
7096 * Is this the end of the [<unknown>] buglet that has been lurking
7097 around for a long time? A little for loop fix in server's
7098 silc_server_command_whois_parse that is used by both IDENTIFY
7099 and WHOIS command. At least, this was a clear bug and a cause
7100 of one type of [<unknown>] buglet.
7102 * WHOIS and IDENTIFY commands call the function
7103 silc_server_command_[whois/identify]_check function even if
7104 we are not router server.
7106 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Added --with-gmp configuration option. If set the GMP
7109 is always compiled in the SILC source tree. If not set then
7110 it is checked whether the system has the GMP3 installed. If
7111 it has then the GMP won't be compiled (the system's headers
7112 and library is used), if it doesn't have it then the GMP is
7113 compiled in the SILC source tree.
7115 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * Changed RSA private exponent generation to what PKCS #1
7118 suggests. We try to find the smallest possible d by doing
7119 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7120 not security fix but optimization.
7122 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Added new config entry [Identity] to fork the server and run
7125 it as specific user and group. A patch from Bostik.
7127 * Imported Dotconf configuration library into lib/dotconf.
7128 This will be used to create the SILC configuration files later.
7129 It will appear in the distsribution after this commit.
7131 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * A big code auditing weekend happening. Auditing code for
7134 obvious mistakes, bugs and errors. Also, removing any code
7137 Removed files for being obsolete:
7139 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7140 inline in the file lib/silcutil/silcbuffer.h)
7142 o lib/silcutil/silcbufutil.c (the header has inline versions)
7144 Changed code to fix possible error conditions:
7146 o The buffer formatting routines now check that the destination
7147 buffer really has enough space to add the data. This applies for
7148 both buffer formatting and unformatting
7149 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7150 unformatting was changed to accomodate following rules:
7151 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7152 sent to the function while XXX_*STRING will not allocate or copy
7153 the data into the buffer. Instead it sets the pointer from the
7154 buffer into the pointer sent as argument (XXX_*STRING used to
7155 require that the pointer must be allocated already). This change
7156 makes this whole thing a bit more consistent and more optimized
7157 (note that the data returned in the unformatting with XXX_*STRING
7158 must not be freed now). The routines return now -1 on error.
7160 o Tried to find all code that use buffer_format and buffer_unformat
7161 and added return value checking to prevent formatting and
7162 especially unformatting errors and possible subsequent fatal
7165 o Changed ske->x and ske->KEY to mallocated pointers in
7166 lib/silcske/silcske.h. Fixed possible data and memory leak.
7168 o Added return value checking to all *_parse* functions. Fixed
7169 many memory leaks as well.
7171 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7172 so that buffer overflows would not happen. All code now also
7173 checks the return value as it can fail.
7175 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added reconnection support to server if the normal server looses
7178 its connection to the router (for example if router is rebooted).
7179 The server performs normal reconnection strategy implemented
7180 to the server. Affected file silcd/server.c.
7182 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Added new packet type SILC_PACKET_SET_MODE that is used to
7185 distribute the information about changed modes (for clients,
7186 channels and clients channel modes) to all routers in the
7187 network. Updated the protocol specification accordingly.
7189 Added functions into silcd/packet_send.c and
7190 silcd/packet_receive.c: silc_server_send_set_mode,
7191 silc_server_set_mode.
7193 Added new files silcmode.[ch] into lib/silccore that implements
7194 the encoding and decoding of Set Mode Payload. Added new type
7195 SilcSetModePayload. Moved the definitions of different modes
7196 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7198 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Oops, a little mistake in server's connection authentication
7201 protocol. The protocol is not ended with FAILURE but with
7202 SUCCESS if the authentication is Ok. :) Affected file is
7205 * Implemented NICK_CHANGE notify handling in server in the file
7206 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7207 the local clients on the channel. After the changing nickname
7208 in router environment snhould work and the [<unknown>] nickname
7209 should appear no more.
7211 The silc_server_replace_id function that receives the Replace ID
7212 payload now sends the NICK_CHANGE notify type also in the file
7213 silcd/packet_receive.c
7215 * Changed WHOIS and IDENTIFY command to support the maximum amount
7216 of arguments defined in protocol specs (3328 arguments). This
7217 fixed a bug that caused problems when there were more than three
7220 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Added extra parameter, command identifier, to the
7223 silc_client_send_command so that explicit command identifier
7226 Changed that ID list routines uses specific command identifier
7227 when sending WHOIS/IDENTIFY requests to the server so that they
7228 can be identified when the reply comes back.
7230 Affected files lib/silcclient/command.[ch],
7231 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7233 * Added `sender' argument to silc_server_packet_send_to_channel
7234 to indicaet the sender who originally sent the packet to us
7235 that we are now re-sending. Ignored if NULL. Affected file
7236 silcd/packet_send.[ch].
7238 * Added some server statistics support in silcd/server_internal.h
7239 SilcServerStatistics structure and around the server code. Also
7240 send some nice statistics information when client is connecting
7243 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7245 * Fixed channel ID decoding in server's JOIN command reply in
7246 silcd/command_reply.c
7248 * Fixed braodcasting of replace ID payload to not to send it if
7249 we are standalone server in silcd/packet_receive.c.
7251 * Fixed all channel message sending routines to not to send
7252 packets to clients that has router set, since they are routed
7253 separately in the same function earlier. Affects file
7254 silcd/packet_send.c and all channel packet sending functions.
7256 * In USERS reply, res_argv[i] are not allocated, the table
7257 is allocated. Thus changed that free the table, not its
7260 * In server's whois_check and identify_check if the client is
7261 locally connected do not send any WHOIS commands - they are not
7264 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Fixed some minor bugs in client when sending WHOIS command. The
7267 arguments was in wrong order.
7269 * Removed statis function add_to_channel from server in
7270 silcd/command.c that was previously used with the joining but
7273 * Tested USERS command in router environment successfully with two
7274 routers, two servers and two clients.
7276 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Reorganized the USERS command and command reply in client library
7279 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7280 When the command is given by user we register a pending command
7281 callback that will reprocess the command after the reply has been
7282 received from the server. When reprocessing the packet we then
7283 display the information. Thus, the USERS information is displayed
7284 now in the command callback instead of in the command reply
7285 callback. The processing of the command is same as previously
7286 when server has sent the command reply in the JOINing process.
7288 * Added to USERS command in silcd/command_reply.c to join the client,
7289 we didn't use to know about, to the channel after we've created
7290 a client entry for it. Also, for clienet we did know already still
7291 check whether it is on the channel or not and add it if not.
7293 * Removed silc_server_command_join_notify as the function and its
7296 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Changed the client's pending command handling to the same as the
7299 server's pending command handling. It is also now possible to
7300 execute command reply functions from other command reply
7301 function as the function callbacks for commands and command
7302 replies are one and same. The pending commands are not static
7303 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7304 in client connection context. Thus, pending commands are server
7305 connection specific as it is convenient.
7307 Changed the function silc_client_command_pending and
7308 silc_client_command_pending_del and added new function
7309 silc_client_command_pending_check. Removed the
7310 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7313 * Added cmd_ident, current command identifier, to the client
7314 connection context in lib/silcclient/client.h to keep track on
7315 command identifiers used in command sending. Client's command reply
7316 function handling now supports the mandatory command identifiers.
7318 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7319 funtions in client to fully support pending command callbacks.
7321 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7322 as one of the arguments to the application in the command reply
7325 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7326 before first releasing SILC but came back. Now it is removed again
7327 and should come back nomore. The FORWARDED flag was used only
7328 by the JOINing procedure by forwarding the command packet to router.
7329 Now, the JOINing procedure has been changed to more generic (due
7330 to various router environment issues) and FORWARDED is not needed
7331 anymore for anything. The protocol specification is yet to be
7334 Now, removed silc_server_packet_forward from server and the flag
7335 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7337 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Renamed NAMES command to USERS command. The NAMES was named that
7340 due to historical reasons. Now it is renamed. Also, rewrote
7341 parts of the USERS command. The nickname list is not sent anymore
7342 by the server. Only Client ID and mode lists are sent in the USERS
7343 command. Changed this also to the protocol specification.
7345 The client now resolves the names and stuff after it receives
7346 the USERS list from the server when joining to the channel.
7348 * WHOIS and IDENTIFY commands has been changed to support multiple
7349 Client ID's per command. One can now search for multiple users
7350 in the network by sending only one WHOIS or IDENTIFY command.
7351 Changed the code and the protocol specifications.
7353 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7354 uses silc_server_command_whois_parse to parse the request. */
7356 * If normal server, do not parse the WHOIS and IDENTIFY requests
7357 before sending it to the router. Saves some time.
7359 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Fixed JOIN command on client library. Wrong number of arguments
7362 used to crash the client.
7364 * Added silc_server_channel_has_global function to check whether
7365 channel has global users or not.
7367 * Added silc_server_channel_has_local function to check whether channel
7368 has locally connected clients on the channel.
7370 * The silc_server_remove_from_one_channel now checks whether the
7371 channel has global users or not after given client was removed from
7372 the channel. It also checks whether the channel has local clients
7373 on the channel anymore. If it does not have then the channel entry
7374 is removed as it is not needed anymore.
7376 * The silc_server_notify now checks on JOIN notify whether the joining
7377 client is one of locally connected or global. If it is global then
7378 the channel has now global users on the channel and that is marked
7379 to the channel entry. Also, it now saves the global client to
7380 global list who is joining and JOINs it to the channel. This is
7381 for normal server, that is.
7383 Changed silc_server_send_notify_on_channel,
7384 silc_server_packet_relay_to_channel and
7385 silc_server_packet_send_to_channel check if we are normal server
7386 and client has router set (ie. global client) do not send the
7387 message to that client, as it is already routed to our router.
7389 * Implemented LEAVE notify type handling in silc_server_notify
7392 * Tested LEAVE command in router environment successfully. Tested
7393 with two routers, two servers and two clients.
7397 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7399 * Implemented SIGNOFF notify type handling in silc_server_notify
7402 * silc_server_remove_id now removes the client entry from all channels
7403 it has joined and thusly sends SIGNOFF notify type.
7405 * Rewrote the NAMES list generation in server by removing two excess
7406 loops. The lists are created now inside one loop.
7408 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * silc_server_remove_channel_user checks now also global list
7411 for channel and client.
7413 * silc_server_new_channel_user checks now both local and global
7414 list for channel and client. Fixed a bug in client id decoding.
7415 Used to decode wrong buffer.
7417 * silc_server_channel_message checks now both local and global
7418 list for channel entry.
7420 * Tested channel joining (hence JOIN) in router environment
7421 successfully. Tested with two routers, two servers and two
7424 * Tested channel message sending in router environment successfully.
7426 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Added silc_server_save_channel_key into server.[ch] to save the
7429 received channel key in Channel Key payload processing. It is
7430 also used in JOIN command reply handling.
7432 Equivalent function silc_client_save_channel_key added into
7433 client.[ch] into client library.
7435 * Changed JOIN command reply to send information whether the channel
7436 was created or not (is existing already) and the channel key
7437 payload. Changed protocol specs accordingly.
7439 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7440 the request was sent by ID and not by nickname. Crashed on
7443 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7446 now correctly save the received data.
7448 * silc_server_free_sock_user_data now notifies routers in the
7449 network about entities leaving the network.
7451 At the same time implemented functions silc_server_remove_id
7452 and silc_server_send_remove_id to receive and send REMOVE_ID
7453 packets. The packet is used to notify routers in the network
7454 about leaving entities. The ID removed will become invalid in
7457 * Added function silc_idlist_del_server into server. Removes and
7458 free's server entry from ID list.
7460 * silc_server_private_message function now checks, if we are router,
7461 that the destination ID really is valid ID, naturally.
7463 * In router when NEW_ID packet is received (for new client) the
7464 hash of the Client ID is saved in the ID Cache but the
7465 client->nickname is set to NULL, instead of putting the hash
7468 IDENTIFY command now also checks that client->nickname must be
7469 valid. If it is not if will request the data from the server who
7470 owns the client. Added new function
7471 silc_server_command_identify_check.
7473 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7474 to set the command to already allocated Command Payload.
7476 * Tested private message sending in router environment with two
7477 routers, two servers and two clients. Fixed minor bugs and now
7480 * Fixed segfault from client's NAMES command. Used to crash if
7483 * Forwarded packets must not be routed even if it is not destined
7484 to the receiver. Changed server code comply with this.
7486 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Added `require_reverse_mapping' boolean value to ServerParams
7489 structure. If TRUE (not default) the server will require that
7490 the connecting host has fully qualified domain name.
7492 If the reverse mapping is not required and hostname could not be
7493 found the IP address is used as hostname.
7495 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Implemented version string checking to both client and server.
7498 The check is incomplete currently due to the abnormal version
7499 strings used in development version of SILC.
7501 * Changed all command functions in server to use the new
7504 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Changed char *data to unsigned char *data in ID Cache system to
7507 support binary data as ID Cache data. Changed code to support
7508 binary data in lib/silccore/idcache.c.
7510 * Renamed silc_server_packet_relay_command_reply to
7511 silc_server_command_reply as it is normal packet receiving
7512 function. Rewrote the function to accept command replys for
7513 servers and not only for clients.
7515 * Mark remote router always as registered server if we are connecting
7516 to it. Otherwise, commands sent by the router to us are ignored.
7518 * All ID List find routines now returns the ID Cache Entry pointer
7519 as well if requested.
7521 * WHOIS command works now in router environment, tested with two
7522 routers, two servers and two clients.
7524 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7525 in router environment (as it is almost equivalent to WHOIS) but
7526 hasn't been tested thoroughly. Added new functions:
7528 silc_server_command_identify_parse
7529 silc_server_command_identify_send_reply
7530 silc_server_command_identify_from_client
7531 silc_server_command_identify_from_server
7533 * Disabled route cache adding because adding two different ID's with
7534 same IP replaces the old cache entry thus giving wrong route.
7535 The entry->router->connection is always the fastest route anyway
7536 so route cache may not be needed. Of course, new routes maybe
7537 established after receiving the ID when the entry->router->connection
7538 might not be anymore the most optimal.
7540 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Add route cache for received ID for fast routing.
7544 * Added silc_server_packet_route to route received packet on router
7545 that is not destined to us.
7547 * Renamed silc_server_get_route to silc_server_route_get.
7549 * Added id_string and id_string_len fields into SilcServer to
7550 include encoded ServerID for fast comparing without excess
7551 encoding of the ID's.
7553 * Cleaned up WHOIS command on server side. Added following static
7556 silc_server_command_whois_parse
7557 silc_server_command_whois_check
7558 silc_server_command_whois_send_reply
7559 silc_server_command_whois_from_client
7560 silc_server_command_whois_from_server
7562 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7563 arguments in command replies. All command functions should be
7564 updated to use this macro.
7566 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7568 * Minor typo fixes on command reply handling on server.
7570 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Added silc_server_command_add_to_channel internal routine to add
7573 the client to the channel after router has created the channel and
7574 sent command reply to the server.
7576 * Added generic silc_server_send_command to send any command from
7579 * Use static buffer with ID rendering instead of duplicating data.
7581 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7583 * Fixed a channel user mode bug when joining to a channel server gave
7584 everybody channel founder rights, oops.
7586 * We mark ourselves as the router of the incoming server connection
7587 if we are router ourselves. This way we can check in some packet
7588 sending functions whether it is locally connected server. For
7589 incoming router connections we put NULL.
7591 * For router sending packets locally means now always sending the
7592 packet cell wide; to local clients and local servers. For normal
7593 server sending packet locally means sending it to only local
7596 * Fixed the JOIN command to really work in router environment. If the
7597 channel is created it is always created by the router. Router is
7598 also responsible of making the initial joining to the channel,
7599 sending JOIN notify to the sending server and distributing
7600 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7601 does not exist server doesn't do anything else but forward the
7602 command to the router which performs everything.
7604 * Added silc_server_send_channel_key function to send the Channel Key
7607 * Added silc_server_create_channel_key to create new channel key. The
7608 channel key is now re-generated everytime someone joins or leaves
7609 a channel, as protocol dictates. Note: channel->key_len is the
7612 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7614 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7615 packet_receive.[ch] to separate packet sending and receiving
7616 routines. The server.[ch] now includes everything else including
7617 actual packet processing (writing and reading data) and other
7620 Renamed silc_server_private_message_send_internal to
7621 silc_server_send_private_message. The routine is still though
7622 used only to relay private messages as server does not send
7623 private messages itself.
7625 Renamed silc_server_new_channel to silc_server_create_new_channel
7626 and added new function sicl_server_new_channel that handles the
7627 incoming New Channel packet. Added also new sending function
7628 silc_server_send_new_channel to send New Channel Payload.
7630 * Added new function silc_server_notify to process incoming notify
7631 packet to the server/router. Server may then relay the notify
7632 to clients if needed.
7634 * Added new function silc_server_new_channel_user to process incoming
7635 New Channel User packet. Router will redistribute the packet and
7636 send JOIN notify to its local clients and locally connected servers
7637 if needed. Normal server will send JOIN notify to its local client
7638 on same channel when received this packet. Added also corresponding
7639 sending function silc_server_send_new_channel_user to sent the
7642 * Added boolean route argument to send_notif_to_channel and
7643 packet_send_to_channel functions to attempt to route the packet
7644 if it is TRUE and send only locally if it is FALSE.
7646 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * silc_server_replace_id now broadcasts the received replace ID
7649 packet if it is not broadcast packet already. The router must
7650 broadcast to inform other routers about changed ID.
7652 * Added backpointer to server's router into SilcServer context in
7653 silcd/server_internal.h.
7655 * Fixed silc_server_packet_broadcast to send correct broadcast
7658 * The channel key is now distributed to the local client as soon
7659 as it is received from the router (in router environment) so that
7660 no other packet may be sent for the channel until client has
7663 * silc_server_remove_channel_user now broadcasts the received
7664 Remove Channel User packet if it is not broadcast packet already.
7665 The router must broadcast to inform other routers about removed
7668 * Added users field into SilcPacketContext that is a reference count
7669 of the context. One can increase the reference count by calling
7670 silc_packet_context_dup which is now changed to just increase the
7671 reference count instead of duplicating the data. The reference
7672 count is decresed by calling silc_packet_context_free that will
7673 free the data after the reference count hits zero.
7675 For now on the packet context and everything allocated into it
7676 (including the raw packet from network) must be freed by calling
7677 the new silc_packet_context_free function. Added also new function
7678 silc_packet_context_alloc that must be used now to allocate the
7679 context. This also means that if a routine is asynchronous from
7680 silc_[client/server]_packet_parse_type the packet context must
7681 be duplicated by calling silc_packet_context_dup. Otherwise it
7682 gets free'd after silc_[client/server]_packet_parse_type returns.
7683 Also, one must remember that if packet is duplicated then its
7684 reference count must be decresed by calling the free function as
7685 many times as it was duplicated.
7687 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7688 from both client and server.
7690 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Made joining to a channel working in router environment.
7694 * Cleaned up JOIN command on server side and create function
7695 silc_server_command_join_channel internal routine to make the
7698 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Changed silc_command_pending list to SilcDList. Also, added
7701 `ident' field to SilcServerCommandPending structure to identify
7702 the reply and to call correct callback.
7704 Added silc_server_command_pending_check function to replace the
7705 corresnponding macro. The silc_command_pending list is not
7708 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7709 to set identifier to previously allocated Command Payload. It
7710 is used to set identifier for command when resending Command
7713 * Added silc_command_payload_encode_payload to encode Command
7714 Payload buffer from SilcCommandPayload structure.
7716 * Added silc_argument_payload_encode_payload to encode Argument
7717 payload buffer from SilcArgumentPayload structure.
7719 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Changed WHOIS command to support router connection on server side.
7722 The whois request is always sent to router unless the server is
7723 standalone server. After server has received the reply from the
7724 router will it send the reply to the client.
7726 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7727 broadcast received broadcast packet. The function is used only
7728 by router. The broadcast packet is always sent to the router's
7731 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7732 render given ID to printable string, for log files for example.
7734 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7736 * Made basic router to router connections working. At least they
7737 can now connect to each other but nothing really works the way
7738 they are supposed - yet.
7740 * Added new initiator token to RouterConnection configuration
7741 file in silcd/serverconfig.[ch]. It is used to tell whether we
7742 are the initiator to the remote router or whether we'll expect
7743 the other end to connect.
7745 * Moved registering of listener task to silc_server_init, hence
7746 the server starts listenning as soon as it is run, even if it
7747 does not have connections to other routers. Let's see how well
7750 * Changed default connection retry timeouts for more suitable in
7753 * Removed cipher and such arguments from silc_idlist_add_client
7754 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7755 Added new function silc_idlist_add_data to add the keys and stuff
7758 * Added SilcIDListData structure and added it to SilcClientEntry
7759 and SilcServerEntry as their first field in the structure. This
7760 way we can explicitly cast the ID entries to the SilcIDListData
7761 structure and get common data for the entries. In past, we had
7762 to first check what type of connection it is and then cast it to
7763 correct ID entry type. Now, we can directly cast the opaque
7764 pointer to the SilcIDListData (no matter what ID entry it actually
7765 is) and get the data needed.
7767 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7769 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7770 in some circumstances even if threre were timeout tasks, though not
7771 IO tasks, but tasks anyway. Now fixed.
7773 * Defined SilcServerConnection structure to hold connection specific
7774 stuff about directly connected servers and routers. The definition
7775 is currently in silcd/server_internal.h. I thought about having
7776 a bit more important role fro this struct but for now it is used
7777 only when connecting to other server (or router actually).
7779 * Added connecting retry support in server when connecting to
7780 router(s). The retry feature implement exponential backoff
7781 algorithm. Also, added SilcServerParams structure to hold default
7782 parameters for server. For now, it include these retry settings
7783 and are hard coded. After server is moded to be as Silc Server
7784 Library this structure will be more important.
7786 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7788 * Changed client librarys channel->clients table to SilcList and
7789 changed code accordingly.
7791 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Changed client's channel table to SilcList and changed code
7794 accordingly. Also changed SilcChannelClientEntry to include back-
7795 pointer to the channel so that client entry can use that structure
7796 as list as well and we have fast cross-reference to the channel.
7797 This change dramatically decreased the complexity of channel
7798 handling with client entry and vice versa (removed one extra
7799 loop when searching for channel entry from many functions).
7801 * Changed server->sim from table to SilcDList and changed code
7804 * NAMES command can now be used from user interface. It will show
7805 the user list on the channel, neatly.
7807 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7808 Code now saves realname of the user if it becomes available.
7810 * Renamed configure.in to configure.in.pre and made ./prepare
7811 script to automatically add correct version string to
7812 configure.in which it creates from configure.in.pre.
7814 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * NAMES command reply now shows users mode with the nickname when
7819 * Moved silc_client_ch[u]mode[_char] functions from
7820 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7821 place sucks, they are utility functions and should be in some
7824 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7826 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7829 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7833 * Added TRQ (efficient deque and list library) into lib/trq. This is
7834 a very good list library that is currently used in the SILC. Defined
7835 SilcList API over the library because I didn't like the API very
7836 much. See lib/trq/silclist.h for the API and examples of how to
7837 use the API. Fixed various places in the code to use the new
7838 SilcList API. The SilcList is meant for lists that has a structure
7839 already defined as a list. It is not suitable to add just some
7840 context to the list (in TRQ, the context is the list actually).
7842 So, I defined SilcDList that can be used for the purpose where
7843 predefined list structure does not exit. This can be used as
7844 such list. Now some context just can be added to the SilcDList.
7845 Currently this list is not used in the SILC just yet, though there
7846 are a lot places where this can replace dynamically allocated
7847 tables and I will fix these places, later, to use SilcDList.
7848 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7849 and use TRQ internally).
7851 Also fixed some annoying warning messages that the original TRQ
7852 code generated. Also minor changes to TRQ's Makefile.in.
7854 * Added support for querying by Client ID to both WHOIS and
7855 IDENTIFY commands into server, as required by the protocol.
7857 * Removed method function pointers from SilcBuffer structure. They
7858 weren't used to anything and just increased the context size for
7859 no good reason. This change also made silc_buffer_alloc and
7860 silc_buffer_free functions inline functions.
7862 * Disabled command flooding detection support until it's fixed so
7863 that it accepts commands in but does not execute them more than once
7866 * Added silc_net_localhost(), to return local hostname, into
7867 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7868 that must be initialized before calling silc_client_init.
7870 * Added new function: silc_server_send_notify_on_channels to send
7871 notify messages to all channels client has joined. It is assured
7872 that the message is sent only once per client.
7874 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7875 lib/silcutil/silcutil.[ch] as silc_format function. The new
7876 function is generic and is used by server as well, not only by
7877 the logging routines.
7879 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7880 the provided version string was not acceptable. Added new function:
7881 silc_ske_check_version into lib/silcske/silcske.h. The function
7882 must be implemented by the application (client or server) and it
7883 does not reside in the SKE library. The function checks the version
7884 string remote end sent.
7886 * Added back pointers (to opaque context and to SilcSocketConnection)
7887 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7889 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7890 duplicate packet context structure.
7892 * Changed `notify' client operation to send same arguments as client
7893 receives from server except for ID's. ID's are mapped to correct
7894 ID entry and that is returned. Also, if channel entry is not sent
7895 by server but the notify is for channel the channel entry is sent
7896 to application (otherwise application doesn't know that it is for
7897 channel (library gets it from packet's Destination ID)).
7899 * Added silc_client_remove_from_channels into client library to
7900 remove a client from all channels it has joined to. Used when
7901 received SIGNOFF notify from server. Added also new function
7902 silc_client_replace_from_channels to replace old ID entry with
7903 new ID entry on all channels. Used when received NICK_CHANGE
7906 * Fixed ID Cache list handling in silc_idlist_get_client in
7907 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7908 to get (or query) client by ID.
7910 * Updated TODO list.
7912 * Added connection authentication status message defined by the
7913 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7914 support for these into the code in client and server side.
7916 * Added generic function silc_client_send_command to send any command
7917 with variable argument list. Application should use this function
7918 to send commands if the command functions provided by the library
7919 does not suite for the application's user interface needs.
7921 * Added new `failure' client operation. Application is notified about
7922 received failure packet if client is executing a protocol. In this
7923 case the protocol's execution has failed.
7925 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7926 is required by the protocol.
7928 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7929 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7932 * Added status flag to SilcSKE object to indicate realtime status
7933 of the SKE protocol.
7935 * Application receives now exactly same command reply arguments as
7936 the library receives from server. However, if ID is received the
7937 corresponding ID entry is returned to the application (eg. Client
7938 ID is mapped to correct SilcClientEntry entry and that is returned).
7939 Changed command_reply client operation due to this change.
7941 * Changed all ID's in commands and in command replys as ID Payloads.
7942 Change affected both client and server side codes.
7944 All ID's sent in SILC network (with execption of ID's in SILC
7945 Packet header) are sent in ID Payload to support variable length
7948 * Server now notifies nick changes and notifies all clients on
7949 the channels about the new nickname (about the new Client ID,
7952 * Implemented CMODE command to change channel modes. Supports all
7953 channel modes defined by the protocol specs except ban and invite
7954 lists. (Also, private channel key mode is supported but support for
7955 setting private channel key in client is missing, thus, this mode
7956 has no effect on client side (except that server requires that the
7957 client uses private channel key and normal channel traffic does not
7960 Also, invite mode works per se, but INVITE command does not work
7961 yet correctly, so you can set channel as invite only channel but
7962 inviting clients to the channel does not work (it is yet to be
7963 thought what's the best way to do it).
7965 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7966 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7967 Implemented CUMODE command to change user's mode on the channel.
7968 Supports all modes defined by the protocol specs.
7970 * Added NAMES command reply to return users modes on the channel.
7972 * Removed unnecessary and slow ciphers from lib/silccrypt.
7974 * Set SO_KEEPALIVE option to connection sockets by default.
7976 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7978 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7979 redefined the Notify Payload into protocol specs.
7981 * Added silc_id_payload_parse_id to get ID directly from raw
7984 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7986 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7987 accept searching by Client ID as well.
7989 * Added support for LEAVE and SIGNOFF notify types in client library.
7991 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7992 to parse ID Payload from raw data.
7994 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7996 * Added flags parameter into silc_ske_assemble_security_properties
7997 function in lib/silcske/silcske.[ch].
7999 * Changed notify client operation to fit better for notify messages
8000 sent by server. The notify payload received from server is now
8001 passed to the application (after parsing it to SilcNotifyPayload).
8002 It is application's responsibility to retrieve the arguments
8003 from the payload and show the message the way it wants. The message
8004 sent by server is implementation specific.
8006 * Changed public keys to comply with the protocol specification.
8007 Old public keys are not supported anymore and are not compatible.
8009 * Removed nickname from Channel Payload as the latest draft removed
8010 it. The client must resolve the nickname from the NAMES command
8011 reply received when it joined the channel.
8013 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8015 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8017 * Fixed some errors in protocol specification drafts.
8019 * Created lib/silccore/silcnotify.c to implement Notify Payload
8020 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8021 generic payloads described by protocol specifications. The file
8022 includes implementations for ID Payload and Argument Payload.
8024 * Changed Command Payload implementation to use the new Argument
8025 Payload. Changed command_xxxx_payload to command_payload_xxxx
8026 to comply with SILC coding conventions.
8028 * Added suppport for Argument Payload handling in Notify Payload
8029 implementation as protocol requires it. Added the new support
8030 into server and client lib as well.
8032 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8034 * Added support for multiple nicknames on same channel. [n] is
8035 added locally to the nickname if there are more than one same
8036 nicknames on the channel.
8038 * Server now sends all nicknames that matched WHOIS request.
8039 Client also shows the list received from server.
8041 * Added TOPIC command to client side. User can now set and show
8042 current topic on channel.
8044 * Added MOTD command to client and server. Also, server sends the
8045 motd when client connects to the server.
8047 * Changed version strings to comply ISO 8601.
8049 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * Fixed protocol error handling in client library. It should now
8052 cope even if the SKE fails for some reason.
8054 * Made new protocol specification drafts for submitting to IETF.
8056 * Implemented TOPIC command to server in silcd/command.c.
8058 * Added two new notify types into lib/silccore/silcnotify.h:
8059 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8060 notify nickname change and topic setting/change on a channel.
8062 * API change of command_reply operation in client library. The
8063 application gets now the status type received from server as well.
8065 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8069 * Cras fixed and optimized the packet handling even further and
8070 it should work now. Minor change to the prototype of function
8071 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8073 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Added new function into lib/silcutil/silcschedule.[ch]:
8076 silc_schedule_with_fd to select() a specified fd. The function
8077 returns after timeout expires or data arrives or goes. The
8078 function is used by packet routines to wait that all data is
8079 received from network.
8081 * Fixed data reading from network in lib/silccore/silcpacket.c.
8082 The code now assures that all data is read from the fd and then
8083 continues packet processing. This was a bug fix since the code
8084 used to drop some data in some circumstances.
8086 * Added new function into lib/silcclient/client.[ch]:
8087 silc_client_start_key_exchange to start key exchange after
8088 connection has been established to server. The code internally
8089 now uses this funtion but its main purpose was to provide it
8090 for applications that perform their own connecting. After
8091 application has created a connection it merely calls this
8092 function to start the key exchange between client and server.
8093 The library takes care of everything else after that.
8095 Updated also lib/silcclient/README to explain the usage of
8098 * Do not send to application information that connection has
8099 been established. Application gets notified it by connect
8102 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Applied cras's patch to add silc_schedule_one function. The
8105 function runs scheduler once and returns.
8107 * Fixed the scheduler after cras messed it up. The timeout
8108 handling works now as it's supposed to work.
8110 * Added into lib/silccore/ silcnotify.h to include notify
8111 message types support. Changed silc_server_send_notify*
8112 functions, in server.[ch], to support those new notify types.
8113 Added the support for the notify types into client library,
8114 as well. Added new notify client operation into ops.h in
8117 * Changed silc_server_packet_send_to_channel to send normal
8118 packets instead of just channel message packets. The function
8119 is now used to send the notify packets to channels. It is not
8120 used to send channel message packets anymore, as server never
8123 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8124 va_arg()s as it seems to require it nowadays. I guess, if SILC
8125 is compiled with older va_arg() the new code should work anyway.
8127 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8129 * Splitted core library. Core library (lib/silccore) includes
8130 now only SILC protocol specific core (and common) components.
8131 Created new utility library (lib/silcutil) that includes more
8132 generic purpose stuff. The stuff for util library was taken
8133 from the old core library. This was minor and easy split.
8135 * Created SILC Client Library (lib/silcclient) that includes
8136 implementation of the SILC client without user interface. This
8137 was major move from silc/ directory. The code has been changed
8138 so that it is transparent towards the user interface. The
8139 silc/ directory includes now the same user interface as before
8140 and it uses the new client library. Read lib/silcclient/README.
8141 Basicly, the client library performs everything else related
8142 to SILC except user interface handling. Also, configuration
8143 files are considered to be part of user interface and library
8144 does not handle them.
8146 This change also changed a lot of structures, function naming etc.
8147 Most important change was that SilcClientWindow object was
8148 renamed to SilcClientConnection in the client library. Created
8149 also new file lib/silcclient/ops.h. Also added new files
8150 silc/local_command.[ch] and silc/client_ops.[ch].
8152 All these changes were made to make it easier for user interface
8153 designers to create what ever user interface for the SILC client
8156 It is also expected that the server will be moved to lib
8157 directory as well and SILC Server Library will be created;
8158 sometimes in the future.
8160 * Removed Local commands from lib/silccore/silccommand.h as
8161 they are application specific and new client library does not
8162 handle any of those anymore.
8164 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8165 old client implementation in silc/.
8167 * Added support for callback functions in SILC_LOG_* macros.
8168 Application can now set its own callbacks that will be called
8169 instead of using the default functions that will always print
8170 the debug messages to stderr (or stdout). Also, debugging can
8171 now be disabled by setting silc_debug to FALSE and re-enabled by
8172 setting it to TRUE. Note, that logging will still work even
8173 if debugging is disabled.
8175 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8176 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8177 silc_log_reset_debug_callbacks.
8179 * To enable debugging in silc client one must give now -d
8180 option on command line.
8182 * Changed silc_schedule_init to automatically allocate task queues
8183 if they are not allocated before calling it.
8185 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Added GMP 3.1 into math library.
8189 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8191 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8192 a channel in SILC network. The packet is used by servers and
8193 routers to notify other routers that user has left a channel.
8194 This little feature was missing until now. Added the feature
8195 to protocol specification as well.
8197 Added functions: silc_server_send_remove_channel_user and
8198 silc_server_remove_channel_user into server.[ch].
8200 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8201 lib/silccore/silcpacket.h. However, they are not implemented
8204 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Fixed joining to a channel and sending channel messages
8207 between server and router. The channel message sending should
8208 now work inside a cell.
8210 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8212 * Fixed the private message sending between server and router.
8213 The private message sending should now work inside a cell.
8215 * Added silc_server_replace_id into server.[ch] to replace
8216 existing ID in the SILC network.
8218 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8219 and silc_idlist_replace_server_id into idlist.[ch] in server.
8221 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Fixed the server to server connections. Server can again now
8224 connect to router. Router to router connections probably does
8227 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8229 * Added dynamic protocol registering support. Now protocols can
8230 registered and unregistered on the fly. Patch by cras.
8232 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Added lib/contrib directory to hold routines that some platforms
8235 don't have but are needed by SILC.
8237 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8238 into lin/contrib to provide getopt() and getopt_long() for
8239 those who don't have it.
8241 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Added AWAY command to client. When away message is set and
8244 client receives a private message packet the client automatically
8245 replies to the sender with the away message.
8247 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8248 bug seemed to be the cause of recent problems when compiling
8251 * Added version detection support to SKE protocol specification
8252 and added the new changes to the SKE implementation as well.
8253 There were other minor changes in the SKE protocol as well.
8255 Many changes in lib/silcske/silcske.[ch] and in
8256 lib/silcske/payload.[ch].
8258 * Added ^U functionality, clear input line. Patch from cras.
8260 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Mainly small bugfixes on core library. Fixed some debugging
8263 logging and buffer overflow in silclog.c.
8265 * Updated config.sub and config.guess on the distribution tree.
8267 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8269 * Added command lagging support in server. Client may execute
8270 commands now only once in two seconds.
8272 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Optimized packet reception. MAC computation and checking is now
8275 also more optimized. A lot previously duplicated code is now
8276 used as generic by both client and server.
8278 * Fixed key pair generation in clientutil.c
8280 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8282 * Added into lib/silccore/silcbufutil.[ch] new function;
8283 silc_buffer_realloc.
8285 * Moved generic packet sending/encryption functions to
8286 lib/silccore/silcpacket.[ch] from client and server. Some
8287 rewriting of the functions.
8289 * Moved all generic packet reception/decryption functions to
8290 lib/silccore/silcpacket.[ch] from client and server. The
8291 packet processing is now much cleaner in both client and server.
8292 These were major changes in both client and server.
8294 * Created many common functions in server to do packet sending.
8295 Previously code were duplicated a lot, this has been removed
8298 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8300 * Rewrote major parts of the ID cache system. Don't know
8301 whether it is better now or not but at least the API is more
8304 * Major rewrite on ID cache stuff on client because of the ID
8305 cache API changes. Added idlist.c to client.
8307 * Also major rewrite on ID cache stuff on server as well.
8308 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8309 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8310 in hand, instead they are all put into the ID cache system now.
8311 All server_idlist_* routines uses ID cache now instead of
8312 traversing its own lists (those lists does not exist anymore).
8313 SilcIDList though still exists. Also, SilcXXXEntry's are
8316 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8318 * Finally made the SKE implementation compliant to the protocol
8319 specification. All mp integers are now binary encoded as
8320 opposed being HEX encoded.
8322 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8325 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8326 functions: silc_[encode/decode]_pem. Also added function
8327 silc_encode_pem_file to PEM encode with newlines ('\n') for
8330 * SILC public keys are now encoded either PEM or binary. Same
8331 option is for private keys as well. By default private keys
8332 are binary encoded and public keys PEM encoded. Silly HEX
8333 encoding were removed.
8335 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8336 function to create fingerprints.
8338 * Fixed a bug in SHA1; does not change the original data anymore.
8340 * Partly implemented INFO command on client and server side.
8341 Fixed CLEAR command. Changes to SERVER command; show current
8342 server(s) when giving command without arguments. Added
8343 VERSION command to client.
8345 * Added check to server that unregistered connections cannot
8346 execute commands (unless it is specificly allowed).
8348 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8350 * Fixed screen refresh.
8352 * Fixed channel joining bug from client. On some circumstances
8353 client tried to join to a channel it had already joined.
8355 * Added public key verification process into client's protocol.c.
8356 The client now verifies the public key from user and saves
8357 it into ~./silc/serverkeys/ directory.
8359 Added into: clientutil.[ch]: silc_client_verify_server_key.
8361 * Changed SKE protocol's silc_ske_initiator_finish function
8362 to accept callback function that verifies the received public
8363 key. Removed old silc_ske_verify_public_key function.
8365 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8367 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8368 silc_pkcs_private_key[_data]_set.
8370 * Made the password and public authentication more cleaner in
8371 server's protocol.c.
8373 * Removed historic and obsolete protocol `channel_auth' from
8374 both client and server.
8376 * Removed wrong way of sending command status messages from
8377 server to client in server's command.c. The old way violated
8378 protocol specification.
8380 Changes to silccore/silccommand.[ch]: removed
8381 silc_command_encode_status_payload -> not needed anymore,
8382 changed silc_command_encode_payload_va to accept extra
8383 argument on variable argument list. The argument type must
8384 now be provided to the function. Also, added new function:
8385 silc_command_encode_reply_payload_va which is same as
8386 normal command_encode_payload_va except command status type
8387 is provided as extra argument.
8389 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8391 * Added ~./silc directory handling. The directory includes the
8392 public and private keys for the client.
8394 Added silc_client_check_silc_dir, silc_client_create_identifier
8395 and silc_client_load_keys.
8397 * Implemented SILC protocol compliant public key. Added public
8398 and private key saving to and loading from files.
8400 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8401 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8402 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8403 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8404 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8406 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8407 silc_pkcs_load_[public/private]_key.
8409 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * Added silc_server_get_route (route.[ch]) to get connection
8412 data for the fastest route for given ID.
8414 * Implemented INVITE command on client and server. The command
8415 were re-defined in the SILC Protocol Specification and the
8416 implementation now complies with the specification.
8418 * Implemented PING command on client and server.
8420 * Implemented NAMES command on client and server. The server side
8421 supports currently only normal server not router server yet.
8422 Some changes to NAMES definition in SILC protocol specification.
8424 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Implemented LEAVE command on client and server.
8428 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8429 again. This change was made to the protocol as well. Server
8430 should not violate the protocol specification anymore.
8432 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8434 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8435 was tested. SOCKS4 was not but should work anyway.
