518 client and server. Protocol TODO #15. Affected files are
519 silcd/command.c, lib/silcclient/command_reply.c. The channel
520 entry is now returned to application in the `command_reply'
523 * Rewrote the version SKE version checking in client libary
524 and in server to use the silc_parse_version_string. Affected
525 files are lib/silcclient/protocol.c, silcd/protocol.c.
527 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
528 commands that was missing it, and updated protocol specs and
529 the server implementation. Protocol TODO #10. The affected
530 file is silcd/command.c.
532 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
533 generic reply to a generic request (REQUEST flag), and
534 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
535 way. A draft-riikonen-silc-flags-payloads-00.txt is written
536 to define the payload for DATA flag. Added the flags to
537 the implementation. Protocol TODO #9. Affected file is
538 lib/silccore/silcchannel.h.
540 Changed the client library to return the message length
541 to application as well in the channel_message and private_message
542 client operations. Affected files are
543 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
544 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
545 and lib/silcclient/client_ops_example.c.
547 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
548 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
549 the channel. Updated protocol specs and impelemented this
550 to client and server. Protocol TODO #6. Affected files are
551 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
552 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
554 Added new options m and M to CMODE command in Irssi SILC
555 client to set these modes.
557 * Deprecated all administrative commands from SILC protocol
558 since they are highly implementation specific commands.
559 Updated protocol specs. Moved the old commands in
560 implementations to private range of command types. Affected
561 files are silcd/command.c, lib/silcclient/command.c and
562 lib/silcclient/command_reply.c. Protocol TODO #8.
564 * Fixed a bug in server where sending unknown command crashes
565 the server. Affected file silcd/command.c.
567 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Added SILC_PROTOCOLVERSION macro to check protocol version
570 of a socket connection. The affected file is
571 lib/silcutil/silcsockconn.h.
573 * Added better error logging in rekey protocol. Affected file
576 * Do not check public key types in SKE during rekey. Affected
577 file lib/silcske/payload.c.
579 * Fixed the rekey protocol with PFS, which was totally broken.
580 Affected file silcd/protocol.c.
582 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
584 * Some client implementations quit network by doing first LEAVE
585 and then immediately SIGNOFF (like Bombyx). We now do check
586 after a short time after LEAVE notify and check whether the
587 client is still valid after LEAVE, and if not we remove it from
588 cache. Affected file is lib/silcclient/client_notify.c.
590 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
592 * Merged version 1.1.4 of zlib. Even if it not currently in use,
593 it's good not to have security holes here.
595 * Fixed a negative refcount situtuation for the config context.
596 Affected file is silcd/serverconfig.c.
598 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
600 * ROBOdoc documented lib/silcutil/silcutil.h.
602 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Optimized even more the SilcPacketContext structure. Now
605 totally saved 16 bytes of memory per context after optimization.
606 Affected files are lib/silccore/silcpacket.[ch].
608 * Made strict checks for valid SILC IDs. Affected file is
609 lib/silccore/silcid.c.
611 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
613 * Changed the object argument for silc_cipher_register,
614 silc_hash_register, silc_hmac_register and silc_pkcs_register
615 to const. Affected files are lib/silccrypt/silccipher.[ch],
616 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
618 * Changed the silc_get_username and silc_get_real_name to
619 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
621 * Fixed the Irssi SILC Client to use the silc_get_username and
622 silc_get_real_name insted of glib routines since the glib
623 routines only corrupt stack. Fixes the Irssi SILC to work in
624 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
626 * Fixed the Irssi to not use g_get_home_dir since it crashes
627 or returns garbage on cygwin and corrupts stack. Added function
628 get_home_dir to Irssi routines. Affected files are
629 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
631 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Made some structure optimizations. SFTP memory FS MemFSEntry
634 entry structure. Optimized SilcTask structure. Optimized
635 SilcPacketContext structure.
637 Affected files lib/silcsftp/sftp_fs_memory.c,
638 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
640 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
642 * And yet again reverted back the config thing since Johnny
643 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
646 * Fixed memory leaks from config object. Affected files are
647 silcd/serverconfig.[ch].
649 * Added support for adding new connections to the server in rehash.
650 After rehash they take effect.
652 Added support for changing the maximum allowed connections in
653 rehash. The number can grow but going smaller is not supported.
655 Added function silc_server_num_sockets_by_remote to the
656 silcd/server_util.[ch].
658 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
660 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
662 * Added preliminary checking during config parsing for a valid
663 public/private key and removed further checks in the code.
664 Affected files are silcd/serverconfig.[ch], server.c.
666 * Moved functions silc_server_drop() and silc_server_daemonise()
667 from server.c to silcd.c since they are stricly related to
668 the application activity.
670 * Reverted a small part of the automatic ref/unref since
671 it caused a double unref in some situations. Affected
672 files are silcd/silcd.[ch], server.c, serverconfig.c.
674 * Added some .cvsignore files in the lib directory.
676 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed silc_net_gethostbyaddr to correctly resolve by
679 address. Affected file lib/silcutil/silcnet.c.
681 * Fixed the notify relaying to client. The HMAC to be used
682 with relayed packets ws wrong and caused decryption failure
683 at the client end. Affected file is silcd/packet_receive.c.
685 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
687 * Created new branch silc_protocol_1_0_branch.
689 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
691 * Changed the silc_server_config_* routines to be SilcServer
692 independent. They are now officially application specific code
693 and not part of generic server implementation. Affected files
694 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
696 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
698 * Added automatic referencing of config context in the
699 silc_server_config_alloc, and automatic unreferencing in the
700 silc_server_config_destroy. Affected files are
701 silcd/serverconfig.[ch], silcd/silcd.c.
703 * Fixed the silc_log_quick handling in the logging routines.
704 It didn't log quickly when it was TRUE. Affected file is
705 lib/silcutil/silclog.c. Also the flush delay was set even
706 if it was 0 in config file. Affected file is
707 silcd/serverconfig.c.
709 * Added support for changing key pair of the server in rehash.
710 Affected file silcd/server.c.
712 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Fixed the TOPIC_SET notify to not cras. It changed the topic
715 too early, before getting the channel entry. Affected file
716 is silcd/packet_receive.c.
718 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
720 * Added functions silc_server_config_[ref/unref], these are used
721 to prevent that the config object is destroyed.
723 No longer directly affect global variables silc_log_quick and
724 silc_log_delay, they are first cached inside the config object
725 and then applied with silc_server_config_setlogfiles().
727 silc_server_config_set_defaults() is now internal to
728 serverconfig.c, there are no reasons to show this internal stuff
731 Affected files are silcd/serverconfig.[ch].
733 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
734 fprintf's to stderr, since some code may be executed again after
735 the server went into the background. Affected files are
738 * Added rehash support. Added function silc_server_rehash() that
739 will perform all the basic tasks of the rehashing procedure.
741 * Added command line option `-x, --hexdump'. This will enable the
742 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
743 The option `--hexdump' implies `--debug'.
745 * Fixed a bad bug in the logging APIs (silcutil library) where
746 the application would crash after calling silc_log_reset_all().
748 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
750 * Fixed the KICKED notify handling in client library to
751 correctly remove the channel and all entries from the
752 channel when I was kicked. This bug crashed the client.
754 Fixed yet another but in KICKED notify handling to remove
755 the kicked client correctly from the channel.
757 Affected file is lib/silcclient/client_notify.c.
759 * Fixed a minor bug in looking up correct client entry
760 in KICKED notify in server. Affected file is
761 silcd/packet_receive.c.
763 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
764 sources correctly to distribution. Fixes --with-gmp option.
766 * Removed the manual rehashing from ID Cache, and changed it
767 to use the SILC Hash Table's auto rehash feature. Affected
768 file is lib/silccore/silcidcache.c.
770 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Fixed a bug in the silc_client_nickname_format function that
773 handles the multiple same nickname formatting. Two clients
774 with same nickname caused problems after the first one left
775 and rejoined. It didn't format the nickname correctly.
776 Affected file is lib/silcclient/idlist.c.
778 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Don't change the topic if olod topic is same as new one.
781 Affected file is silcd/packet_receive.c.
783 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
785 * Added cross-reference support to the SILC Documentation
786 generator. All types across all HTML files are now cross-
787 referenced. Affected files util/robodoc/generator.c and
788 scripts/silcdoc/silcdoc.
790 * Added file lib/silcutil/silctypes.h to include all the
791 arithmetic type definitions and some macros. Removed
792 includes/bitmove.h and moved macros to silctypes.h.
794 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
796 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
798 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Added `type' argument to silc_id_payload_parse_id function which
801 now returns the type of the ID to the sent pointer. Affected
802 file is lib/silccore/silcid.[ch].
804 * Added check for CMODE_CHANGE notify type that mode change is
805 allowed by the sender. Affected file silcd/packet_receive.c.
807 * Added check for CUMODE_CHANGE notify type that mode change is
808 allowed by the sender. Affected file silcd/packet_receive.c.
809 Added the ID type as CUMODE_CHANGE notify type as argument
810 to the `notify' client operation. Affected files are
811 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
813 * Added function silc_client_add_server to the client library.
814 Added support for resolving also channel and server info when
815 received unknown entity in notify packet. Affected files are
816 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
818 * Added function silc_command_get_status to return the command
819 status from the command reply's argument payload. Affected files
820 are lib/silccore/silccommand.[ch].
822 * Added check for KICKED notify type that the kicking is
823 allowed by the client. Affected file silcd/packet_receive.c.
825 * Created function silc_get_input which can be used to get input
826 (echo on or off) from user on command line. Affected files are
827 lib/silcutil/silcutil.[ch].
829 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Optimized silc_server_packet_relay_to_channel function.
832 Added new function silc_channel_message_payload_encrypt which
833 can be called directly if channel message payload needs to
834 be encrypted and is already encoded (no need to call _encode
835 function). Packet relaying is now done by router without any
836 extra memory allocations. Affected files are
837 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
840 * Fixed the INVITE notify handling. It took wrong arguments
841 as invite list and invite delete. Affected file is
842 silcd/packet_receive.c.
844 * Added check for TOPIC_SET notify type that the topic change is
845 allowed by the client. Affected file silcd/packet_receive.c.
847 * Added check for INVITE notify type that inviting is allowed by
848 the client. Affected file silcd/packet_receive.c.
850 * Changed the silc_server_client_on_channel to return the
851 SilcChannelClientEntry as well. Moved the function
852 silc_server_check_cmode_rights to server_util.[ch].
853 Affected files are silcd/server_util.[ch], silcd/command.c.
855 * Added function silc_server_check_umode_rights to check whether
856 changing client's user mode is allowed. Added check for
857 UMODE_CHANGE notify type that the umode change is allowed
858 by the client. Affected files are silcd/server_util.[ch],
859 silcd/packet_receive.c and silcd/command.c.
861 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
863 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
864 ID length. It ignored that ID can be IPv6 based as well.
865 Affected file lib/silccore/silcpacket.h.
867 * Fixed the silc_id_id2str and silc_id_str2id to take the
868 IPv6 address offset's into consideration. Affecte file is
869 lib/silccore/silcid.c.
871 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed the internal Unix scheduler functions to check for
874 NULL context they may receive. The affected file is
875 lib/silcutil/unix/silcunixschedule.c.
877 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
879 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
880 can specify different directory with --home command line
881 parameter. Affected files irssi/src/silc/core/client_ops.c,
884 * SILC-specific commands aren't now executed if the active server
885 isn't of SILC-type, so there won't be problems with having
886 IRC and SILC protocol support in same client. Affected files
887 irssi/src/silc/core/silc-channels.c, silc-servers.c,
890 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Improved the signal support in SILC Schedule. Added new
893 function silc_schedule_signal_call which is used by application
894 to mark a signal to be called. It is now safe to perform
895 any kind of tasks in signal callbacks since it is guaranteed
896 that the application specified signal callback is called
897 after the signal is over. Affected files are
898 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
900 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
902 * Added `name' field to SilcChannelPrivateKey to represent
903 application given name for the key. Moved also the context from
904 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
905 Added the `name' argument also to the function
906 silc_client_add_channel_private_key.
908 Added function silc_client_current_channel_private_key to set the
909 current channel private key in use.
911 Added "change" command to KEY command which can be used to change
912 the current channel private key. Bound the command also to
915 Also affected files lib/silcclient/client_channel.c,
916 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
918 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added silc_rng_get_byte_fast function in to the
921 lib/silccrypt/silcrng.[ch].
923 * Changed the interface of silc_packet_assemble and the
924 silc_packet_send_prepare. If silc_packet_assmble is now
925 called the application does not call silc_packet_send_prepare
926 because the library will call it automatically. These
927 interfaces now also return a reference to the outgoing buffer
928 which includes the assembled packet, which the application can
929 use to encrypt the packet.
931 Affected files are lib/silccore/silcpacket.[ch],
932 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
933 silcd/packet_send.c, server_backup.c and packet_receive.c.
935 * Fixed a packet sending bug on very high load, where outgoing
936 packet queue wasn't handled correctly and packets got corrupted.
937 Affected files are lib/silcutil/*/silc*sockconn.c,
938 lib/silcclient/client.c and silcd/server.c.
940 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Added macro SILC_PACKET_DATALEN which can be used during
943 packet assembling to check whether the data to be added to
944 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
945 len is truncated until it fits it.
947 Added checks for maximum length of channel message payload and
948 private message payload also.
950 Added checks for maximum packet length in server and in
953 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
954 lib/silcclient/client.c, lib/silccore/silcchannel.c and
955 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
956 lib/silcclient/client_prvmsg.c.
958 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
960 * Added silc_server_packet_queue_purge call to the
961 silc_server_disconnect_remote to assure that all data in the
962 queue before disconnecting is sent to the network. Affected
965 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
967 * Added the deleting of server's own ID cache entry to the
968 silc_server_free function. Free also everything else that
969 has been allocated in silc_server_init. The affected file
972 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Added functions silc_parse_version_string, silc_version_to_num,
975 and silc_ske_parse_version to parse SILC protocol style version
976 strings. Affected files lib/silcutil/silcutil.[ch] and
977 lib/silcske/silcske.[ch].
979 * Added new configuration params: version_protocol, version_software
980 and version_software_vendor to specify what version the remote
981 host must at least be to be able to connect to server. The vendor
982 string can be regex matched too. Added new function
983 silc_server_connection_allowed to check maximum number of allowed
984 connections, and allowed versions for incoming connections.
985 Affected files are silcd/server.c, server_util.[ch] and
988 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Added preliminary support for signals in scheduler. The
991 signals we care about are now blocked always when the scheduler
992 is locked. This way we can synchronise the use of signal with
993 scheduler. It is guaranteed that when signal occurs the scheduler
994 is not locked, and thus new tasks can be safely added to the
997 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
998 to silc_schedule_internal_init and silc_schedule_internal_uninit.
999 Added new platform specific routines
1000 silc_schedule_internal_signals_[un]block and
1001 silc_schedule_internal_signal_[un]register.
1003 Added new functions to SILC Schedule API:
1004 silc_schedule_signal_[un]register. Each signal that application
1005 is going to use should be registered to the scheduler.
1007 Affected files are lib/silcutil/silcschedule.[ch],
1008 lib/silcutil/*/silc*schedule.c.
1010 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1012 * Check for unauthenticated client and server in the
1013 silc_server_new_client and silc_server_new_server functions.
1014 Affected file silcd/packet_receive.c.
1016 * Added function silc_string_is_ascii to check whether given
1017 string is 7-bit ASCII string. Affected files are
1018 lib/silcutil/silcutil.[ch].
1020 * Added function silc_id_is_valid_server_id into the
1021 silcd/serverid.c and added checking for valid Server ID's in
1022 silc_server_new_server. The Server ID must always be based
1023 on the server's public IP address.
1025 * Added logging of DISCONNECT packet message in the server.
1026 Affected file silcd/server.c.
1028 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Changed all library interfaces that use Global RNG to also
1031 accept SilcRng as argument. Affected files are
1032 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1033 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1034 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1035 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1036 lib/silccrypt/rsa.c.
1038 * Added function silc_pkcs_generate_key to the
1039 lib/silccrypt/silcpkcs.[ch] for applications so that they
1040 don't need to do pkcs->pkcs->init calls anymore.
1042 * Remove SilcSocketConnection from the SFTP API since it really
1043 wasn't needed there. The application has the information
1044 saved in its contexts anyway and the SFTP layer doesn't need
1045 know about it. Affected files lib/silcsft/silcsftp.h and
1046 lib/silcsftp/sftp_[server/client].c.
1048 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1049 The SilcSimContext is not SilcSim.
1051 * Fixed possible buffer overflows in silc_id_render in the
1052 lib/silcutil/silcutil.c.
1054 * On EPOC the global crypto module lists are not used at all
1055 in the crypto library. Added support for using the constant
1056 algorithm list on EPOC. Affected files are
1057 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1060 * Fixed the handling of third parameter of KICKED notify, since
1061 it was mistakenly updated to SILC Protocol 1.0 even though it
1062 is to be included in 1.1. Since it is not in 1.0 it is not
1063 mandatory, and this fix now handles it only if it is provided,
1064 and it is not error if it is not provided. Affected file
1065 lib/silcclient/client_notify.c.
1067 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1069 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1070 client. Affected file irssi/src/silc/core/client_ops.c.
1072 * Merged with Irssi 0.8.4 from irssi.org CVS.
1074 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1076 * Check for valid socket connection in client entries before
1077 sending any messages. Fixes a crash, but doesn't fix some
1078 other underlaying bug that is lurking there. Affected
1079 file silcd/packet_send.c.
1081 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1083 * $usermode, $cumode and $cumode_space expandos shouldn't do
1084 anything with non-SILC server records. Affected file
1085 irssi/src/silc/core/silc-expandos.c
1087 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1089 * Fixed the silc_net_check_[host/local]_by_sock to support
1090 IPv6 bound sockets as well. Now they can return IPv6 addresses
1091 as well. Affected file lib/silcutil/silcnet.c.
1093 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1094 Affected lib/silcutil/unix/silcunixnet.c.
1096 * Fixed ID rendering (at least on some platforms, not NetBSD)
1097 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1099 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1101 * Added silc_hash_public_key and silc_hash_public_key_compare
1102 functions to be used with SilcHashTable. They can be used to
1103 hash public keys and compare public keys in hash table. Affected
1104 file lib/silcutil/silcutil.[ch].
1106 * Added support for specifying multiple public keys for Client
1107 connection section in server configuration file. This makes it
1108 possible to accept multiple public keys from same host, or to
1109 make a section that accepts any incoming host, and have the
1110 accepted public keys listed in the section.
1112 Added functions silc_sever_[find/get]_public_key, added the
1113 support for this actually to all connection sections but only
1114 the Client section is currently allowed to specify multiple
1117 Affected files are silcd/server.c, server_internal.h,
1118 command.c, protocol.c, server_util.[ch], packet_receive.c.

1124 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1126 * If silc_debug is TRUE, also output standard logging messages
1127 to stderr with the debug output.
1129 Made silc_log_reset_all() flushing all channels before returning.
1130 Also fixed some documentation typos.
1132 Affected files are lib/silcutil/silclog.[ch].
1134 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1136 * Fixed the server to check correctly the amount of connections
1137 from single host, by checking also the type of the connection.
1138 Fixed also the comparison of number of connections and number
1139 of allowed connections. Affected files are silcd/server.c,
1142 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed the USERS command reply to save the user's mode on the
1145 channel as well. Fixed JOIN command reply to check whether a
1146 client is on channel already and not join it twice. Affected
1147 file lib/silcclient/command_reply.c.
1149 * Added new file silc-expandos.c into irssi/silc/core/ to return
1150 various stuff for various signal for the statusbar etc. updating.
1151 Now Irssi SILC client prints channel user modes etc. on the
1154 * The user mode (like server/router operator changes) is now shown
1155 on the Irssi SILC client's statusbar. The affected files are
1156 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1158 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1160 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1161 to SILC_SCHEDULE_[UN]LOCK macros.
1163 * Added more error printing to logs in server code. Affected
1164 files silcd/server.c and silcd/protocol.c.
1166 * Fixed -S option parsing in Irssi SILC Client. Affected file
1167 irssi/src/silc/core/silc-core.c.

1194 * Changed all integer type names:
1195 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1196 to avoid collisions with other libraries using same type names
1199 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Added `prefer_ipv6' argument to the functions
1202 silc_net_gethostbyname[_async]. If it is TRUE it will return
1203 IPv6 address over IPv4. If FALSE IPv4 address is returned
1204 even if IPv6 address was found. Affected files
1205 lib/silcutil/silcnet.[ch].
1207 * Added support silc_net_create_connection[_async] to fallback
1208 to IPv4 address if IPv6 address could not be used (like if
1209 it doesn't work on a specific system). Affected file in
1210 lib/silcutil/unix/silcunixnet.c.
1212 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1218 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Added automatic extern "C" { ... } for C++ compilers so the
1221 application does not need to define them. Affected file
1222 includes/silcincludes.h.
1224 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1225 old name went against naming convention. Applications now
1226 include "silcclient.h" instead of "clientlibincludes.h".
1227 Removed includes/clientlibincludes.h, it is redundant now.
1229 * Renamed includes/version.h to silcversion.h.
1231 * Added really preliminary support for OS/2 into the util
1232 library. Only thread & mutex API is implemented, others
1233 are still to be implemented. Created the lib/silcutil/os2/
1234 directory. Created also file includes/silcos2.h.
1236 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1243 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1245 * Added proper initializations to silc's irssi code, so it's
1246 now possible to load it as module. Affected files
1247 irssi/src/silc/core/silc-core.c,
1248 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1267 * Added `user_count' to the SilcChannelEntry which now tells the
1268 number of users on the channel. The user count is now saved
1269 in normal server of global channels as well. Affected files
1270 silcd/server.c, idlist.h, packet_receive.c and command.c.
1272 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1273 include file utility functions.
1275 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1276 instead of calling directly OS routines.
1278 * Fixed NICK change printing in Irssi SILC Client. Fixed
1279 KICKED notify printing in Irssi SILC Client. Affected file
1280 irssi/src/silc/core/client_ops.c.
1282 * Fixed a NICK change bug in client library, to not recreate the
1283 client_entry->channels hash table everytime nick is changed.
1284 Affected file lib/silcclient/client.c.
1286 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1288 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1289 the SKE interface a bit.
1291 * Fixed padding problem in PKCS#1. The padding was not actually
1292 random since the random number generator was used incorrectly.
1293 This security bug affects only when encrypting with PKCS#1, and
1294 it is not currently used at all in SILC. SILC only use signing
1295 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1297 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1308 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1309 key_exchange_timeout, conn_auth_timeout, connections_max,
1312 Implemented all the new config settings handling in the server.
1314 Optimized the use of SKE Mutual flag usage. Use it only
1315 if connection authentication protocol is not based in public
1318 Renamed all SilcServerConfigSection* to SilcServerConfig*
1319 to have a bit shorter names.
1321 Affected files silcd/serverconfig.[ch], server.[ch], and
1324 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1346 section structs, now identifying the param directly.
1348 Added CONFIG_FREE_AUTH macro in config file parsing.
1350 Affected files are silcd/serverconfig.[ch].
1352 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1354 * Fixed command line parameter handling. All SILC initialization
1355 is now done in silc_core_init() which also fixes autoconnecting
1358 Affected files irssi/src/silc/core/silc-core.c,
1359 irssi/src/fe-text/silc.c.
1361 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1363 * Added new configuration options and blocks:
1364 keepalive_secs, reconnect_count, reconnect_interval,
1365 reconnect_interval_max, reconnect_keep_trying and
1366 require_reverser_lookup. Added ConnectionParam block, and
1367 implemented the connection parameters when connecting as
1368 initiator and when accepting connections as responder.
1370 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1371 whether given configuration value has been given already.
1373 Affected files silcd/serverconfig.[c], server.[c].
1375 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1376 algorithm parts and created new file silcalgs.conf, that
1377 is now included from the example_silcd.conf.in.
1379 * Optimized the silc_server_connect_to_router_second to take
1380 the connection configuration object from the SilcServerConnection
1381 object instead of finding it during the connecting phase.
1382 Added the configuration object to SilcServerConnection struct.
1383 Affected files silcd/server_internal.h, server.c.
1385 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1387 * Add the client on channel after it was resolved at the
1388 channel message receiving, and it was not already on the
1389 channel. Affected file lib/silcclient/client_channel.c.
1391 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1393 * Fixed the public key authentication to allocate always the
1394 destination signature buffer instead of using static buffer.
1395 Affected file silcd/protocol.c.
1397 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1406 config file, allowing both public key and passphrase based
1407 authentication to be set at the same time.
1409 Added `prefer_passphrase_auth' setting in config file which
1410 can be used to set to prefer passwd auth if both passwd and
1411 public key is set. If not set, public key is preferred.
1412 This has effect only when being initiator (responder will try
1415 Added support for authentication with passphrase and public key
1416 at the same time. The passphrase is tried first always since
1417 it is faster to check.
1419 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1421 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1450 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1451 as header filenames.
1453 * Removed lib/silcclient/README and created HTML file
1454 lib/silcclient/silcclient_using.html, which is now included
1455 as part of Toolkit documentation.
1457 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed CUMODE_CHANGE notify handling to change the mode of
1460 correct client. Affected file lib/silcclient/client_notify.c.
1462 * Make silc_rng_alloc fail if it cannot allocate the sha1
1463 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1465 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1467 * Fixed the file transfer's key agreement payload to include
1468 zero port also if the hostname is NULL because it could not
1471 Call file transfer monitor callback now also if error occurs
1472 during key agreement protocol.
1474 Changed the silc_client_file_send interface to return the
1475 SilcClientFileError instead of session id. The session ID
1476 is returned into pointer provided as argument.
1478 Check that the file exists locally before sending the
1479 file transfer request at all.
1481 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1483 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1488 is changed and +k mode is set in the channel. Affected file
1489 irssi/src/silc/core/silc-channels.c.
1491 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1492 SILC_LOG_WARNING to give out Warning and not Error. Affected
1493 file lib/silcutil/silclog.c.
1495 * Fixed the channel message payload decryption in the function
1496 silc_channel_message_payload_decrypt to not modify the original
1497 buffer before it is verified that the message decrypted
1498 correctly. Otherwise, next time it is called with correct
1499 channel key it won't encrypt since the payload is corrupted.
1500 Affected file lib/silccore/silcchannel.c.
1502 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1512 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1514 * Fixed a bug in hash table internal routine for traversing
1515 the table with foreach callback. The current entry may
1516 become invalid in the callback but it was referenced after
1517 the callback returned.
1519 Do not allow auto rehashing of hash table during the
1520 silc_hash_table_foreach operation, for same reasons as it is
1521 not allowed for SilcHashTableList. Affected files are
1522 lib/silcutil/silchashtable.[ch].
1524 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1526 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1527 Win32 DLL. extern's in header files are now declared with
1530 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1532 * Fixed private message handling. It used some old code that
1533 caused the client to crash. Affecte file is
1534 lib/silcclient/client_prvmsg.c.
1536 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1538 * Added function silc_client_add_channel,
1539 silc_client_replace_channel_id, and removed functions
1540 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1541 from client library.
1543 * Added cross reference of the joined channels to the
1544 SilcClientEntry, and changed the SilcChannelEntry's
1545 users list to SilcHashTable. The affected files are
1546 lib/silcclient/idlist.[ch].
1548 * Fixed a bug in hash table tarversing. While the hash table
1549 is traversed with SilcHashTableList the table must not be
1550 rehashed. It is now guaranteed that auto rehashable tables
1551 are not rehashed while tarversing the list. Also defined that
1552 silc_hash_table_rehash must not be called while tarversing
1553 the table. Added function silc_hash_table_list_reset that must
1554 be called after the tarversing is over. The affected files are
1555 lib/silcutil/silchashtable.[ch].
1557 * Changed all hash table traversing to call the new
1558 silc_hash_table_list_reset in server and in client library.
1560 * Added function silc_client_on_channel to return the
1561 SilcChannelUser entry if the specified client entry is joined
1562 on the specified channel. This is exported to application as
1563 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1565 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed founder regaining problem with JOIN command on normal
1568 server. The notify for mode change must be sent always and
1569 not only if !cmd->pending. Affected file silcd/command.c.
1571 * Fixed the WHOWAS command's reply sending to support the
1572 lists correctly. Affected file silcd/command.c.
1574 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1576 * When sending JOIN command to router for processing the
1577 sender's old command identifier was not saved back to the
1578 sender's command context, fixed now. The affected file is
1581 * Create the key in JOIN command of the router did not return
1582 the channel key, added check for this. Affected file is
1585 * Fixed a channel ID update bug in JOIN command reply. Do
1586 not directly upgrade the ID but call the function
1587 silc_idlist_replace_channel_id if the ID was changed.
1588 Affected file silcd/command_reply.c.
1590 * Fixed memory leaks from command calling if it would fail.
1591 Affected file silcd/command.c.
1593 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1595 * Applied patches from cras:
1597 Memory leak fixes around libaries, irssi window resize fix,
1598 new silclist.h and silcdlist.h, all extern inline changed to
1601 * Removed dotconf from lib/dotconf, not needed anymore.
1603 * Removed TRQ from lib/trq, not needed anymore.
1605 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1606 with server connections. Later this will be configurable
1607 in config file after new config file is done. Affected file
1610 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1612 * Fixed a crash in server related to channel announcements.
1613 Affected file silcd/server.c.
1615 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1617 * Fixed memory leaks in silc_server_create_new_channel*
1618 functions. Affected file silcd/server.c.
1620 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1621 which ID was changed. This way the router will send the
1622 user list for the channel again, and server won't be in
1623 desync in some rare circumstances. Affected file is
1624 silcd/packet_receive.c.
1626 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Check for NULL socket pointer in the function
1629 silc_server_packet_send_to_channel_real. Affected file
1630 silcd/packet_send.c.
1632 * Fixed the BAN notify handling to correctly remove ban
1633 list. Affected file silcd/packet_receive.c.
1635 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1637 * Fixed some header addition to Toolkit distribution in
1638 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1640 * Added lib/silcclient/client_ops_example.h as an template
1641 file for application programmers to quickly start using
1642 the SilcClientOperation functions in their application.
1643 Updated the lib/silcclient/README as well to tell about this
1644 nice file made available.
1646 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1648 * Call silc_server_remove_from_channels when removing client
1649 entry when NO_SUCH_CLIENT_ID was received. Affected file
1650 is silcd/command_reply.c.
1652 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1654 * Added server & router operator statistics updating. Affected
1655 file silcd/packet_receive.c and silcd/command.c.
1657 * Fixed the SERVER_SIGNOFF notify handling on normal server
1658 not to save the history information for clients. Same was
1659 fixed earlier in remove_clients_by_server function, but not
1660 here. Affected file silcd/packet_receive.c.
1662 * Raised the default connection-retry count from 4 to 7 in
1663 server. Affected file silcd/server.h.
1665 * Cancel any possible reconnect timeouts when we start the
1666 key exchange. Affected file silcd/server.c.
1668 * Do not reconnect on connection failure when SCONNECT was
1669 given. Affected files silcd/server.[ch].
1671 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1673 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1675 * Fixed the NICK command to always give the unformatted
1676 nickname to the one giving the NICK command. If unformatted
1677 nickname is cached already it will be formatted and the
1678 local entry will always get the unformatted nickname.
1679 Affected file lib/silcclient/idlist.c.
1681 * Fixed some double frees from client library commands.
1682 Affected file is lib/silcclient/command.c.
1684 * Fixed CUMODE command in server to assure that no one can
1685 change founder's mode than the founder itself, there was a
1686 little bug. Affected file silcd/command.c.
1688 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1690 * Removed the SilcClientCommandDestructor from the client
1691 libary, it is not needed anymore. Affected files are
1692 lib/silcclient/silcapi.h, command[_reply].[ch],
1693 client_notify, idlist.c.
1695 * Fixed GETKEY command to first resolve client, and then
1696 resolve the server only if the client was not found, instead
1697 of resolving both at the same time. Affected file is
1698 lib/silcclient/command.c.
1700 * Added silc_client_start_key_exchange_cb and lookup the
1701 remote hostname and IP address before starting the key
1702 exchange with server. The affected file is
1703 lib/silcclient/client.c.
1705 * The server's public key is now saved using the IP address
1706 of the server and not the servername for the filename.
1707 The hostname public key filename is checked as an fall back
1708 method if the IP address based filename is not found.
1710 Fixed the GETKEY command to save the fetched server key
1711 in correct filename.
1713 Print the remote server's hostname now when new key is
1714 received during connection process. Affected file is
1715 irssi/src/silc/core/client_ops.c.
1717 * Return always our own public key to the client if it asks
1718 for it with GETKEY command. Affected file silcd/command.c.
1720 * Removed the use_auto_addr variable from default config
1721 file since it was in wrong section. Affected file is
1724 * Fixed TOPIC_CHANGE notification to not route it when it
1725 was sent using silc_server_send_notify_to_channel function.
1726 Affected file silcd/command.c.
1728 * Fixed silc_server_send_notify_kicked to send the kicker's
1729 Client ID also, it was missing. Affected files are
1730 silcd/command.c, silcd/packet_send.[ch].
1732 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1734 * Do not save client history information in SERVER_SIGNOFF.
1735 Fixes the bug in normal server that it does not detect
1736 the client becoming valid after the server becomes back
1737 online. Affected file silcd/server_util.c.
1739 * Added `sock_error' field into the SilcSocketConnection
1740 context. When error occurs during socket operation (read
1741 or write) the error is saved. Added also new function
1742 silc_socket_get_error to return human readable socket error
1743 message. Affected files are lib/silcutil/silcsockconn.[ch],
1744 lib/silcutil/unix/silcunixsockconn.c, and
1745 lib/silcutil/win32/silcwin32sockconn.c.
1747 * The server now prints the socket error message in the
1748 signoff for client. Affected file silcd/server.c.
1750 * Fixed the `created' channel information sending from router
1751 to server in JOIN command. Checks now whether the channel
1752 really was created or not and set it according that.
1754 Fixed the JOIN command to use the client entry's current
1755 ID during the joining procedure instead of the one it sent
1756 in the command (it is checked though), since it can change
1757 between the packet processing and command processing, and
1758 would just case unnecessary pain in the client end. Affected
1759 file silcd/command.c.
1761 * Fixed a channel key payload sending to use correct channel
1762 ID when the server was forced to change the channel's ID by
1763 router. Router sent the key payload with the old Channel ID.
1764 Affected file silcd/packet_receive.c.
1766 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1768 * Call silc_server_save_channel_key only if the key payload
1769 was provided in the JOIN command's command reply. Affected
1770 file silcd/command_reply.c.
1772 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1774 * Fixed silc_mp_sizeinbase to return the value correctly with
1775 MPI. Affected file lib/silcmath/mp_mpi.c.
1777 * Fixed the stop_server signal to correctly stop the scheduler
1778 and gracefully stop the server when SIGTERM or SIGINT signals
1779 are received. Affected file silcd/silcd.c.
1781 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1783 * Simple handling of TERM and HUP signals. Also added some log
1784 flushing call around. Affected file is
1787 * Fixed small bugs in silclog.c. Now buffering output will take
1788 effect after 10 seconds since startup: This will ensure that
1789 no important startup messages are lost. Also output redirection
1790 will preserve original format ([Date] [Type] message).
1791 Affected file is lib/silcutil/silclog.c.
1793 * Added two options to the config file, in the logging section:
1794 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1795 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1797 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1799 * Do not print the warning about log files not being initialized
1800 more than once to avoid excess logging. Affected file is
1801 lib/silcutil/silclog.c.
1803 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1804 the SIM copying in make install in Makefile.am.pre.
1806 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1808 * Rewritten silclog APIs. Globally interesting changes follows:
1809 silc_log_set_files() changed to silc_log_set_file().
1810 silc_log_set_callbacks() changed to silc_log_set_callback().
1811 ROBOdoc documented silclog header file.
1812 SilcLogCb now returns bool to wether inihibit the default
1813 handler or not (to keep the old behaviour return always TRUE).
1814 The new APIs should also fix the problem of the
1815 silcd_error.log file that was written in the current directory.
1818 Log files streams will remain opened after silc_log_set_file()
1819 call, means less CPU usage notably on high traffic servers.
1820 File streams are now full buffered, and flushed to the disk
1821 every 5 minutes, lesses HD activity and CPU usage.
1822 Messages can be redirected, allowing admins to configure
1823 one single logfile for all server messages.
1824 the silc_log_quick global variable to activate fast-logging.
1825 Affected files lib/silcutil/silclog.[ch]
1827 * Changed some code to conform new silclog APIs. Affected
1828 files are doc/example_silcd.conf.in, silcd/server.c
1829 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1832 * Fixed a memory leak that could occur in some situations.
1833 Affected file silcd/serverconfig.c.
1835 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1837 * Added the silc_client_del_client to remove the client from
1838 all channels as well. Affected file lib/silcclient/idlist.c.
1840 * Fixed the client library to correctly remove the client
1841 from all channels when the client entry is being destroyed.
1842 Affected file lib/silcclient/client_notify.c, command.c.
1844 * Added auto-nicking support to the client library. If the
1845 applicatio now sets client->nickname it will be sent to the
1846 server after connecting by the library. This way for example
1847 SILCNICK (or IRCNICK) environment variables will have effect
1848 and always change the nickname automatically to whatever
1849 it is wanted. Affected file lib/silcclient/client.[ch].
1851 * Renamed silc_server_command_bad_chars to the
1852 silc_server_name_bad_chars and moved it to the
1853 silcd/server_util.[ch]. Added also new function
1854 silc_server_name_modify_bad to return nickname that
1855 includes bad characters as new nickname without those
1856 bad characters. This check and modify is now used in
1857 silc_server_new_client when the username is initially set
1858 as nickname, so it must be checked to be valid nickname.
1859 Affected file silcd/packet_receive.c.
1861 * The nickname length is now taken from the packet for real
1862 and not trusted to strlen() since it clearly can return
1863 wrong length for nickname including bad characters. This
1864 also applies to channel names. Affected file silcd/command.c.
1866 * Removed the lib/silcsilm/modules directory. Modules are now
1867 compiled into the lib/silcsim. Fixed the copying of the
1868 modules to follow symbolic links in Makefile.am.pre.
1870 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1872 * Fixed silc_string_regexify list creation. Fixes bugs with
1873 BAN and INVITE commands in server. The affected file is
1874 lib/silcutil/unix/silcunixutil.c.
1876 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Removed the command destructor entirely from the server's
1879 command and command reply routines. It is not needed, and
1880 its usage was buggy and caused crashes. Affected files are
1881 silcd/command[_reply].[ch].
1883 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Cancel protocol and NULL sock->protocol if timeout
1886 occurred during protocol. Affected file silcd/server.c.
1888 * Cancel protocol timeouts always before calling the final
1889 callback, to assure that after final callback is called
1890 no other state will be called for the protocol anymore.
1891 Affected file silcd/protocol.c.
1893 * Print error log if incoming connection configuration could
1894 not be found. Affected file silcd/server.c.
1896 * Fixed JOIN command to correctly save the founder mode
1897 to the client on normal SILC server, when the channel
1898 was created by the router. Affected file silcd/command.c.
1900 * Fixed LIST command (hopefully) to send correct reply
1901 packets. Affected file silcd/command.c.
1903 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * The silc_packet_receive_process now returns FALSE if the
1906 read data was invalid packet, and TRUE if it was ok.
1908 The server now checks that if unauthenticated connection
1909 sends data and its processing fails the server will close
1910 the connection since it could be a malicious flooder.
1912 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1914 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Make sure the warning about error opening a log file is
1917 printed only once and not everytime it fails (produces
1918 too much useless log). Affected file lib/silcutil/silclog.c.
1920 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1922 * Made the silc_server_daemonise() function more readable.
1923 Affected file silcd/server.c.
1925 * Pid file is now optional, the user may comment it out from
1926 the config file. Removed define SILC_SERVER_PID_FILE, we
1927 don't need a default any longer. Affected file
1928 configure.in.pre, lib/Makefile.am.pre.
1930 * Make some use of the pid file. The server now dies at startup
1931 if it detects a valid pid file on his path. The server would
1932 die anyway in this circumstance, because of the bind() failure.
1933 Affected file silcd/silcd.c.
1935 * No longer compiling lib/dotconf.
1937 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Fixed JOIN command parsing not to crash. Affected file
1940 lib/silcclient/command.c.
1942 * Fied the NICK_CHANGE notify to add the new client entry
1943 even it is resolved. This removes an <[unknown]> nick
1944 thingy bug in the client. Affected file is
1945 lib/silcclient/client_notify.c.
1947 * Do not try to allocate 0 bytes (efence does not like it)
1948 in lib/silccore/silccomand.c when encoding payload.
1950 * Do not take IRCNICK as nickname in Irssi SILC client since
1951 it is not possible to set nickname before hand connecting
1952 the server (TODO has an entry about adding auto-nicking
1955 * Changed the silc_server_command_pending to check whether
1956 there already exists an pending entry with the specified
1957 command, command identifier and pending callback. This is
1958 to fix IDENTIFY and WHOIS related crashes that may register
1959 multiple pending commands with same identifier. Affected
1960 file silcd/command.c.
1962 * Fixed the server to reconnect to the router even if it
1963 was already reconnecting and EOF was received. This to
1964 fix a possibility that the server wouldn't ever try to
1965 auto-reconnect to the router. Affected file silcd/server.c.
1967 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Fixed the server's password authentication to use the
1970 length of the locally saved password, and not the one
1971 sent in the packet. Affected file silcd/protocol.c.
1973 * Fixed same password authentication problem in the
1974 Authentication Payload handling routines in
1975 lib/silccore/silcauth.c.
1977 * Yet another password authentication problem fixed with
1978 channel password handling in silcd/command.c.
1980 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * If first character of string in silc_parse_userfqdn is '@'
1983 then do not parse it. Affected file is
1984 lib/silcutil/silcutil.c.
1986 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1988 * Fixed minor bug in IDENTIFY command reply sending, which
1989 caused various weird problems during JOIN when it was
1990 resolving names for users. Affected file silcd/command.c.
1992 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * Fixed the IDENTIFY command reply sending to chech better valid
1995 clients. It was possible to send incomplete list of replies.
1996 Affected file silcd/command.c.
1998 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Added silc_client_command[s]_[un]register functions now to
2001 dynamically register the commands in client library. Removed
2002 the static table of commands. This allows the client library
2003 to call commands without causing the application to know about
2004 what commands library has called.
2006 Removed the INFO command reply kludge to detect when the command
2007 was called by library. Now library use its own command reply
2008 function for INFO command.
2010 Added function silc_client_command_call to call a command.
2011 Application can use it to call command, not access the structure
2014 Now all commands that are sent by the client library (not
2015 explicitly sent by application) use own command reply functions.
2017 Affected files around lib/silcclient/ and in
2018 irssi/src/silc/core/.
2020 * Fixed the WHOIS command reply sending to chech better valid
2021 clients. It was possible to send incomplete list of replies.
2023 Fixed the WHOIS and IDENTIFY to send the request to router
2024 if normal server did not do it and did not find any results.
2026 Affected file silcd/command.c.
2028 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2030 * Moved the internal data from SilcClient context into its
2031 own file, not accesible to application. Affected files
2032 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2033 and other files in client library.
2035 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Added doc/examples installation target in Makefile.am.pre.
2040 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2043 commands the found client entry will be removed from the
2044 cache, after notifying application about the error. Affected
2045 file lib/silcclient/command_reply.c.
2047 * Changed the /MSG to check for exact nickname user gave, and
2048 not let `nick' match `nick@host' if it is only one found. Now,
2049 user must type the exact nickname (like nick@host2) even if
2050 there are no more than one same nicks found. This is to avoid
2051 a possibility of sending nickname to wrong nickname since
2052 `nick' could match `nick@host'. Affected file is
2053 irssi/src/core/silc-servers.c.
2055 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Do not print "you are now server operator" or similar when
2058 giving /away command. Affected files are
2059 irssi/src/silc/core/client_ops.c, silc-servers.h.
2061 * Made the silc_server_command_pending_error_check to send
2062 the same command reply payload it received back to the
2063 original sender of the command. This way all arguments
2064 that was received by the server will be received by the
2065 client too. Affected file silcd/command.c.
2067 * Added the silc_idcache_add to return the created cache entry
2068 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2070 * Add global clients to expire if they are not on any channel.
2071 This is because normal server will never know if they signoff
2072 if they are not on any channel. The cache expiry will take
2073 case of these entries. This is done by normal servers only.
2074 The affected files are silcd/command_reply.c,
2075 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2077 * If server receives invalid ID notification for WHOIS or
2078 IDENTIFY and the ID exists in the lists, it is removed.
2079 Affected file silcd/command_reply.c.
2081 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2082 in client then client entry that it matches is searched and
2083 the nickname is printed on the screen for user. Affected
2084 file irssi/src/silc/core/client_ops.c.
2086 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Use cache entry expire time in the LIST command reply to
2089 purge old entries from the cache after the LIST command
2090 reply has been received. This way we don't have non-existent
2091 entries in the cache for too long. Affected file is
2092 silcd/command_reply.c.
2094 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * If we are normal server, and we've not resolved client info
2097 in WHOIS or IDENTIFY from router, and it is global client,
2098 we'll check whether it is on some channel. If it is not
2099 then we cannot be sure about its validity and will resolve it
2100 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2101 file silcd/command.c.
2103 * Search channel by name (if possible) rather than by ID
2104 in IDENTIFY command's command reply. Affected file is
2105 silcd/command_reply.c.
2107 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2110 Updated specs and implemented it. Affected file silcd/command.c,
2111 silcd/packet_send.c and silcd/packet_receive.c.
2113 * Implemented the <founder auth> payload handling in the JOIN
2114 command. If provided all conditions for channel joining
2115 except requirement to provide correct passphrase can be
2116 overrided by the channel founder. Updated the protocol specs.
2117 Affected file silcd/command.c.
2119 Added support for founder auth in JOIN command in client
2120 library. Fixed the parsing of the JOIN command now to support
2121 all options as they should be. The affected file is
2122 lib/silcclient/command.c.
2124 * Optimized the WHOIS and IDENTIFY commands to send the request
2125 to router only if it includes nicknames or other names. If
2126 they include only IDs then check the local cache first before
2127 routing. Affected file is silcd/command.c.
2129 * Added channels topic announcements. Affected file is
2130 silcd/packet_receive.c and silcd/server.c.
2132 * Fixed the silc_server_send_notify_topic_set to really destine
2133 the packet to channel. Affected file silcd/packet_send.c.
2135 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2136 library. Affected file lib/silcclient/client_notify.c.
2138 * Added UMODE announcements. Affected file silcd/server.c.
2140 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Memory leak fixes in:

2149 lib/silccore/silccommand.c
2150 lib/silccore/silcidcache.c
2155 * ROBOdoc documented the lib/silcske/groups.h file and a
2156 bit changed the interface for better.
2158 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2160 * Update the client entry context in the ID cache after
2161 nick change. Affected file lib/silcclient/command.c.
2162 Fixes the CUMODE command when regaining founder privileges,
2163 and a little WHOIS problem.
2165 * Fixed silc_net_gethostbyname to correctly call the
2166 inet_ntop. Affected file lib/silcutil/silcnet.c.
2168 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2170 * Added IPv6 support checking to the configure.in.pre, added
2171 also --enable-ipv6 option to override the check. Affected
2172 file configure.in.pre.
2174 * The silc_thread_create now calls the start function
2175 directly if threads support is not compiled in. Removes
2176 ugly #ifdef's from generic code. Affected files are
2177 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2179 * Added silc_net_gethostby[name/addr]_async to asynchronously
2180 resolve. Affected files are lib/silcutil/silcnet.[ch].
2182 * Added support for rendering IPv6 based server, client and
2183 channel IDs. Affected file lib/silcutil/silcutil.c.
2185 * Added support for creating IPv6 based server IDs. Affected
2186 file is silcd/serverid.c.
2188 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2190 * Added silc_net_gethostby[addr/name] into the
2191 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2192 routines. Added silc_net_is_ip[4/6]. Affected file is
2193 lib/silcutil/unix/silcunixnet.c. All routines that take
2194 address as argument now supports both IPv4 and IPv6 addresses.
2196 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2198 * Fixed LIST command reply sending in server. Affected file
2201 * Server now sends the kicker's client ID in the KICK notify
2202 to the kicked client. Affected file silcd/command.c.
2204 * The client library now parses the kickers client ID and
2205 UI displays it. Affected files lib/silcclient/client_notify.c
2206 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2208 * Made all payload parsing function prototypes consistent.
2209 They all take now const unsigned char * and uint32 pair as
2210 the payload data instead of SilcBuffer. Changes all around
2211 the source tree. Other unsigned char* -> const unsigned char*
2212 changes around the tree as well.
2214 * Optimized SFTP client and server packet sending not to
2215 allocate new buffer for each packet but to recycle the
2216 first allocated buffer. Affected files are
2217 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2219 * Optimized the SFTP client to use SilcList instead of
2220 SilcDList for requests, because it is faster. Affected file
2221 is lib/silcsftp/sftp_client.c.
2223 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2224 into lib/silccore/silcid.[ch].
2226 Renamed silcpayload.[ch] into silcargument.[ch].
2228 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * If client entry is deleted with active key agreement
2231 session, abort the session.
2233 The silc_client_abort_key_agreement now calls the completion
2234 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2236 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2239 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2241 * Don't use __restrict in older GCC's. Affected file is
2242 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2244 * silc_net_localhost now attempts to reverse lookup the
2245 IP/hostname. Affected file lib/silcutil/silcnet.c.
2247 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2248 command. It can be used to gain founder privileges at
2249 the same time when joining the channel.
2251 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2252 kicker's client ID as well. Updated protocol specs.
2254 Defined that the server must send SILC_COMMAND_IDENTIFY
2255 command reply with error status to client who sent
2256 private message with invalid client ID.
2258 Updated the protocol specification.
2260 * Added silc_server_send_command_reply to send any
2261 command reply. Affected file silcd/packet_send.[ch].
2263 * Added silc_id_payload_encode_data to encode ID payload
2264 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2266 * The server now send IDENTIFY command reply with error
2267 status if client ID in private message is invalid. Affected
2268 file silcd/packet_receive.c.
2270 * Save the server key file with server's IP address in
2271 the filename instead of hostname. The affected file is
2272 irssi/src/silc/core/client_ops.c.
2274 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2279 * Added libtool support for compiling shared objects in
2280 lib/silcsim. Affected file configure.in.pre and
2281 lib/silcsim/Makefile.am. Original patch by cras.
2283 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Pid file configuration, and server's config file fixes
2286 patch by toma. Updated CREDITS file.
2288 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Fixed silc_client_channel_message to not try to decrypt
2291 the message twice if it resolved the destination client
2292 information. This could cause of dropping one channel
2293 message. Affected file lib/silcclient/client_channel.c.
2295 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2298 lib/silcclient/client.c. This function is used when the SILC
2299 Client is run under some other scheduler, or event loop or
2300 main loop. On GUI applications, for example this may be
2301 desired to used to run the client under the GUI application's
2302 main loop. Typically the GUI application would register an
2303 idle task that calls this function multiple times in a second
2304 to quickly process the SILC specific data.
2306 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2308 * Fixed silc_server_drop() for dropping the supplementary
2309 groups as well, this could cause a security hole on some
2312 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2317 * Write PID file after dropping privileges. Added -F option
2318 to run server on foreground. A patch by debolaz.
2319 Affected files silcd/server.c, silcd/silcd.c.
2321 * Fixed MOTD to return the MOTD file server name. Affected
2322 file silcd/command.c.
2324 * Added INFO command reply handling to the Irssi SILC Client.
2325 Affected file irssi/src/silc/core/client_ops.c.
2327 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Fixed the silc_idcache_list_* routines to really support
2330 the dynamic list. Fixes a crash. Affected file is
2331 lib/silccore/silcidcache.c.
2333 * Fixed the LIST command reply to really call LIST command's
2334 pending callbacks. Affected file silcd/command_reply.c.
2336 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Update conn->local_entry->nickname after giving NICK
2339 command. Affected file lib/silcclient/command.c.
2341 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2343 * Added the [pid] option to the silcd configuration file
2345 Affected files: serverconfig.[ch] and silcd.c
2347 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Save fingerprint in WHOIS command reply in server.
2350 Affected file silcd/command_reply.c.
2352 * Fixed NICK commands pending callback registration.
2353 Affected file lib/silcclient/command.c.
2355 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Use ++server->cmd_ident when sending commands in server,
2358 instead of random number. Affected file silcd/command.c.
2360 * Fixed GETKEY command reply to call actually GETKEY pending
2361 command callbacks. Affected file silcd/command_reply.c.
2363 * A bit stricter check for nicknames. Check for same nickname
2364 in NICK command also. Affected file silcd/command.c.
2366 * Do not call INFO command everytime client ID changes, only
2367 during first connecting. Affected file lib/silcclient/client.c.
2369 * Set the new nickname only after successful command reply for
2370 NICK command is returned by server. Affected file
2371 lib/silcclient/command.c.
2373 * Remove nicknames from nicklist during server_signoff notify.
2374 Should fix /NAMES bit more. The affected file is
2375 irssi/src/silc/core/silc-channels.c.
2377 * Added `fingerprint' field to the SilcIDListData in the
2378 silcd/idlist.h to hold the fingerprint of the client's
2381 Send the fingerprint of the client's public key in WHOIS
2384 Affected files silcd/command.c, and silcd/idlist.[ch].
2386 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2387 create fingerprint from given data.
2389 * Show the fingerprint of the client's public key in WHOIS.
2390 Affected files irssi/src/module-formats.[ch] and
2391 irssi/src/silc/core/client_ops.c.
2393 * Format the multiple same nicknames also during JOIN and
2394 NICK_CHANGE notifys. Affected file is
2395 lib/silcclient/client_notify.c.
2397 * Do not print error on screen for invalid private message
2398 payload since it can come if someone is sending private
2399 messages with wrong key. Affected file
2400 lib/silccore/silcprivate.c.
2402 * Fixed multiple concurrent /PING crash. Affected file
2403 lib/silcclient/command.c.
2405 * Changed the wrong ID encoding. All IP addresses must be
2406 in MSB first order in encoded format. They were encoded
2407 wrong and was in LSB format. Affected files are
2408 silcd/serverid.c, lib/silcutil/silcutil.c.
2410 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2412 * Call the `connect' client operation through the scheduler
2413 in case of error. Affected file lib/silcclient/client.c.
2415 * Call the `failure' client operation even if the error
2416 occurred locally during a protocol. Affected file is
2417 lib/silcclient/protocol.c.
2419 * Added support of sending LIST command to router from normal
2420 server. This way normal server can get list of all channels
2421 in the network too. Fixed the channel list sending in the
2422 server too. Affected files are silcd/command.c, and
2423 silcd/command_reply.[ch].
2425 * Added silc_server_update_channels_by_server and
2426 silc_server_remove_channels_by_server. They are used during
2427 disconnection of primary router and in backup router protocol.
2428 Affected file silcd/server_util.[ch], silcd/server.c and
2429 silcd/server_backup.c.
2431 * Fixed channel adding to global list in IDENTIFY command
2432 reply in server. Affected file silcd/command_reply.c.
2434 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * If the incoming packet type is REKEY or REKEY_DONE process
2437 that packet always synchronously. Fixes yet another MAC
2438 failed error on slow (dialup) connections. Affected file
2439 lib/silcclient/client.c and silcd/server.c.
2441 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Call check_version SKE callback for initiator too. Affected
2444 file lib/silcske/silcske.c.
2446 * Implemented fix for security hole found in the SKE that was
2447 fixed in the specification few days back; the initiator's
2448 public key is now added to the HASH value computation.
2449 Added backwards support for the old way of doing it too, for
2450 old clients and old servers. Affected file is
2451 lib/silcske/silcske.c.
2453 * Enabled mutual authentication by default in SKE. If initiator
2454 is not providing mutual authentication the responder will
2455 force it. This will provide the proof of posession of the
2456 private key for responder. The affected files are
2457 lib/silcclient/protocol.c and silcd/protocol.c.
2459 * Do not cache anymore the server's public key during SKE.
2460 We do mutual authentication so the proof of posession of
2461 private key is done, and if the server is authenticated in
2462 conn auth protocol with public key we must have the public
2463 key already. Affected file silcd/protocol.c.
2465 * Added new global debug variable: silc_debug_hexdump. If
2466 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2467 file lib/silcutil/silclog.[ch].
2469 * Fixed compilation warning due to char * -> const char *.
2470 Affected files lib/silcutil/silcnet.h, and
2471 lib/silccore/silcauth.[ch].
2473 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Fixed CMODE command when new channel key was created. If
2476 the creation failed the old key was removed. Next time giving
2477 same command would crash the server since the old key was
2478 freed already. Affected file silcd/command.c.
2480 * Fixed the silc_server_announce_get_channels to not crash
2481 on reconnect. Affected file silcd/server.c.
2483 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Added silc_log_set_debug_string function to set a regex
2486 string to match for debug output. Only the function names,
2487 or filenames matching the given debug string is actually
2488 printed. This way it is possible to filter out those debug
2489 strings that user is not interested in.
2491 Fixed a bug in silc_string_regexify.
2493 Affected files lib/silcutil/silclog.[ch], and
2494 lib/silcutil/unix/silcunixutil.c.
2496 * Changed the -d options in both server and Irssi SILC client
2497 to take the debug string as argument. Affected files
2498 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2500 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Added silc_hash_babbleprint to create a Bubble Babble
2503 Encoded fingerprint. The encoding is developed by Antti
2504 Huima (draft-huima-babble-01.txt), and it creates human
2505 readable strings out of binary data. Affected file
2506 lib/silccrypt/silchash.[ch].
2508 * Print the babble print now in addition of fingerprint as well
2509 in Irssi SILC client. Affected files are
2510 irssi/src/fe-common/silc/module-formats.[ch],
2511 irssi/src/fe-common/silc/core/client_ops.c.
2513 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Fixed a security problem found in SKE. The initiator's
2516 public key too is now added to the HASH hash value creation
2517 which is signed by the responder to create the SIGN value.
2518 This will prevent anyone in the middle to lie to the responder
2519 about the initiator's public key. If this is done now, the
2520 man in the middle will get caught. Updated the protocol
2523 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Better installation directory handling. Configure module
2526 paths and other paths automatically to example_silc* files
2527 in doc/. A patch by toma.
2529 * Fixed compiler warning from MPI library, and from SILC RNG.
2532 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2533 It can be configured with ./configure. A patch by toma.
2535 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Find correct make to use in prepare-clean. A patch by
2538 toma. Affected file prepare-clean.
2540 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2542 * Added irssi variables use_auto_addr, auto_bind_ip,
2543 auto_bind_port and auto_public_ip.
2545 * Changed the interface for silc_client_send_key_agreement
2546 in lib/silcclient/silcapi.h
2550 irssi/src/silc/core/silc-core.c
2552 lib/silcclient/silcapi.h
2553 irssi/src/silc/core/silc-channels.c
2554 lib/silcclient/client_keyagr.c
2557 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Added silc_pkcs_public_key_compare to compare two
2560 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2562 * Check that the client who set the founder mode on the
2563 channel is the same client that is giving the founder
2564 mode to itself. It is done by comparing the saved public
2565 key (it is saved even in the authentication is passphrase).
2566 Affected file silcd/command.c.
2568 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Do not process packet for disconnected socket connection.
2571 Affected file lib/silccore/silcpacket.c.
2573 * Process the DISCONNECT packet through scheduler in the
2574 client library. Affected file lib/silcclient/client.c.
2576 * Fixed the silc_client_packet_parse to not to increase
2577 the packet sequence number if the conn->sock and the
2578 current socket connection is not same. This can happen
2579 for example during key agreement when the conn includes
2580 multiple socket connections (listeners). Affected file
2581 lib/silcclient/client.c.
2583 * The sender of the file transfer request now provides also
2584 the pointer (listener) for the key exchange protocol. If
2585 the listener cannot be created then it sends empty key
2586 agreement and lets the receiver provide the listener.
2588 Added `local_ip' and `local_port' arguments to the
2589 silc_client_file_send. If they are provided they are used,
2590 if not then it will attempt to find local IP address, if
2591 not found or bind fails then the remote client will provide
2594 Affected files are lib/silcclient/client_ftp.c and
2595 lib/silcclient/silcapi.h.
2597 * Extended the FILE SEND command to support defining the
2598 local IP and port for key exchange listener. They are
2599 optional. Affected file irssi/src/silc/core/silc-servers.c.
2601 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Defined to WHOIS command reply the sending of fingerprint
2604 of the client's public key (if the proof of posession of the
2605 corresponding private key is verified by the server).
2606 Updated to the protocol specification.
2608 * Added support of receiving the client's public key's
2609 fingerprint in command reply in client library. Affected
2610 file is lib/silcclient/command_reply.c, and
2611 lib/silcclient/idlist.[ch].
2613 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Do not send over 128 chars long nickname to the server
2616 in NICK command. Affected file lib/silcclient/command.c.

2670 preserve the WHOWAS info for the client. Affected file
2671 silcd/server_util.c.
2673 * Fixed SERVER_SIGNOFF notify handling in the server. The
2674 server is now able to process incoming SERVER_SIGNOFF notify
2675 for a server that it doesn't even know about. It will remove
2676 the clients provided in the notify. Affected file
2677 silcd/packet_receive.c.
2679 * Check for partial packet in data queue after every packet that
2680 was found from the queue. Return and wait for more data if
2681 there is partial data in queue. Affected file is

2701 * Wrote a help file for FILE command.
2703 * Added silc_rng_global_get_byte_fast to get not-so-secure
2704 random data as fast as possible. Random data is read from
2705 /dev/urandom if available and from the SILC RNG if not
2706 available. It is used in padding generation. Affected file
2707 lib/silccrypt/silcrng.[ch].
2709 * All packets in client library are now processed synchronously.
2710 Optimized packet processing a lot. Affected file
2711 lib/silcclient/client.c.

2722 * Assure that silc_client_notify_by_server_resolve does not
2723 resolve the client information multiple times. If it cannot
2724 be found by the first it cannot be found at all. Affected
2725 file lib/silcclient/client_notify.c.
2727 * Fixed WHOWAS command reply calling. Affected file
2728 lib/silcclient/command_reply.c.
2730 * Removed all references to silc_idlist_get_client from the
2731 Irssi SILC client since that call is internal call used by
2732 the library. The Irssi SILC client will use now client
2733 retrieval functions found in silcapi.h.
2735 * Fixed a bug in resolving nickname info before sending
2736 private message. It used freed memory. Affected file
2737 irssi/src/silc/core/silc-servers.c.
2739 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Assure my_channels statistics cannot go negative in server.
2742 Affected files silcd/server.c, silcd/server_util.c.

2758 * Added silc_net_localip to return local host's IP address.
2759 Affected file lib/silcutil/silcnet.[ch].
2761 * If key exchange or rekey protocol is active for a connection
2762 parse all packets syncronously since there might be packets
2763 in packet queue that we are not able to process without first
2764 processing packets before them. Affected file silcd/server,
2765 lib/silcclient/client.c.
2767 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2768 whether library should continue processing the packet.

2815 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2816 is incomplete and is being resolved, it won't be resolved
2819 Make sure also that USERS command reply does not resolve
2820 twice information. Affected file is
2821 lib/silcclient/command_reply.c.
2823 Make sure that silc_client_get_clients_by_list does not
2824 resolve twice same information.
2826 * Check for valid client->id in the silc_server_free_client_data.
2827 Affected file silcd/server.c.
2829 * Fixed /GETKEY nick@server not to crash if the server entry
2830 is not found. Affected file lib/silcclient/command.c.
2832 * Fixed the silc_server_check_cmode_rights to check the

2840 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Call the silc_server_udpate_servers_by_server in the
2843 primary router that comes back online in the backup resuming
2844 protocol. Otherwise it routes packets wrong. Affected file
2845 silcd/server_util.[ch], silcd/server_backup.c.
2847 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2849 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2850 lib/silcutil/silcbuffmt.[ch].
2852 * Redefined the SILC packet header to include the padding
2853 length. Affected file lib/silccore/silcpacket.[ch].
2855 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2856 length for maximum padding up to 128 bytes). Affected
2857 file lib/silccore/silcpacket.h.
2859 * Removed all backwards support for old 0.5.x MAC thingies.
2860 The SILC packet header change makes it impossible to be
2861 backwards compatible.
2863 * Send the ENDING packet with timeout in the backup resuming
2864 protocol. This is to assure that all routers has connected
2865 to the primary router. Affected file silcd/server_backup.c.
2867 * Changed the RNG to take the first IV from random data. It
2868 used to take it from zero actually. Changed the RNG also
2869 to use /dev/urandom during session. /dev/random is used
2870 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2872 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Changed the SILC packet header to have the first two bytes
2875 (the packet length) encrypted. Affected files aroung the
2876 code tree, lib/silccore/silcpacket.[ch]. Removed the
2877 SilcPacketCheckDecrypt callback. It is not needed anymore
2878 since the silc_packet_receive_process will determine now
2879 whether the packet is normal or special.
2881 * Implemented the unidirectional MAC keys. Affected files
2882 lib/silcske/silcske.c, silcd/protocol.c and
2883 lib/silcclient/protocol.c.
2885 * Implemented the packet sequence number to the MAC computation.
2886 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2887 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2888 lib/silcclient/protocol.c.
2890 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Allow backup router to announce servers. All servers
2893 announced by backup router are added to the global list
2894 automatically. Update hte server's socket to our primary
2895 router also when backup router announces a server.
2896 Affected file silcd/packet_receive.c.
2898 * Do not update the client->router in the function
2899 silc_server_udpate_clients_by_server if the client is on
2900 global list. We might fail to find any specific server
2901 for locally connected clients and local cell clients. They
2902 should still use the `from' and not `to' as client->router.
2903 This fixes backup router resuming protocol. Affected file
2904 silcd/server_util.c.
2906 * Decrease channel statistics count only if the channel
2907 deletion worked. Affected files are silcd/server.c and
2908 silcd/server_util.c.
2910 * Added silc_server_update_servers_by_server to update origin
2911 of all server entries. Used during backup router protocol.
2912 Affected files silcd/server_util.[ch], silcd/server.c. and
2913 silcd/backup_router.c.
2915 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2916 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2917 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2918 lib/silccrypt/silchmac.c.
2920 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Assure that router cannot reroute the same channel message
2923 to the sender. Affected file silcd/packet_receive.c.
2925 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Made better checks that the channel message is not sent
2928 to the router it came from. Affected file is
2929 silcd/packet_send.c. Fixed memory leak too.
2931 * Announce informations for incoming router connection, but
2932 only after checking if it is replaced by backup router.
2933 Affected file silcd/packet_receive.c.
2935 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Fixed the backup resuming protocol to work in multiple
2938 router environment. Affected file silcd/server_backup.c.
2940 * Route packet only to one router in the function
2941 silc_server_packet_send_to_channel. Affected file is
2942 silcd/packet_send.c.
2944 * Fixed silc_server_send_notify_dest to set the broadcast
2945 flag. Fixed the silc_server_send_notify_topic to actually
2946 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2947 Affected file silcd/packet_send.c.
2949 * Changed the SFTP Filesystem interface. Changed the
2950 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2951 the filesystem operation function. The SilcSFTPFilesystem
2952 is now a context that is allocated by all filesystem allocation
2953 functions and it already includes the operations structure
2954 and filesystem specific context. It is given as argument
2955 now to the silc_sftp_server_start. This made the interface
2956 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2957 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2959 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Changed the backup router adding and getting interfaces
2962 in the server. The router that will be replaced by the
2963 specified backup router is now sent as argument. Affected
2964 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2967 * Added silc_net_addr2bin_ne to return the binary form of
2968 the IP address in network byte order. Affected files
2969 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2971 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Check for existing server ID in silc_server_new_server
2974 and in silc_server_connect_to_router_final and remove the
2975 old entry if it exists. Affected file silcd/packet_receive.c,
2978 * Send the channel message always to only one router, either
2979 in upstream or downstream. Affected file is
2980 silcd/packet_send.c.
2982 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2984 * Wrote the definition of the backup resuming protocol to the
2985 protocol specification.
2987 * Removed one redundant channel key generation from normal
2988 server during joining procedure. Removed one redundant
2989 channel key sending from server to router during joining
2990 procedure. Affected file silcd/command.c.
2992 * Made minor bugfixes to the backup router resuming protocol.
2993 Affected file silcd/server_backup.c, server.c.
2995 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Added --disable-asm configuration option. Affected files
2998 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3001 * Implemented the backup resuming protocol that is used to
3002 resume the primary router position in the cell after the
3003 primary router comes back online. Affected files
3004 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3005 and silcd/server_util.[ch].
3007 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Sleep two (2) seconds after sending QUIT command to server.
3010 Affected file lib/silcclient/command.c.
3012 * Assure that if outgoing data buffer is pending do not force
3013 send any data. Affected file silcd/packet_send.c.
3015 * Assure that if outgoing data buffer is pending do not force
3016 send any data. Affected file lib/silcclient/client.c.
3018 * Implemented the backup router support when the primary router
3019 goes down. The servers and routers can now use the backup
3020 router as new primary router without loosing connectivity.
3022 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3025 in the server to indicate disabled entry. All data read
3026 from the connection will be ignored and no data is sent
3027 for entry that is disabled. Affected files are
3028 silcd/idlist.h, silcd/server.c.
3030 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Created SFTP client and server test programs in the
3033 lib/silcsftp/tests directory.
3035 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Implemented memory filesystem (virtual filesystem) for
3038 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3041 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3043 * Implemented the SFTP (SSH File Transfer Protocol) to the
3044 lib/silcsftp. It includes SFTP client and SFTP server
3047 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Moved lib/silccore/silcprotocol.[ch] to the
3050 lib/silcutil library.
3052 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3053 take variable argument list pointer as argument. Affected
3054 file lib/silcutil/silcbuffmt.[ch].
3056 * Added silc_buffer_set function that is used to set data
3057 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3058 Affected file lib/silcutil/silcbuffer.h.
3060 * Changed various routines in the core library to use the new
3061 silc_buffer_set instead of allocating new buffer only for
3064 * Added 64-bit value formatting and unformatting support to the
3065 silc_buffer_[un]format routines. Affected file is
3066 lib/silcutil/silcbuffmt.[ch].
3068 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3069 to includes/bitmove.h.
3071 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Fixed channel user mode saving in client library. Affected
3074 file lib/silcclient/command[_reply].c.
3076 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Defined the file transfer to the SILC Protocol. Added
3079 new packet type SILC_PACKET_FTP and defined File Transfer
3080 Payload. The mandatory file transfer protocol is SFTP
3081 (SSH File Transfer Protocol). Affected file in addition
3082 of the internet draft is lib/silccore/silcpacket.h.
3084 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3085 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3086 is used as part of backup router protocol when the primary
3087 router of the cell is back online and wishes to resume
3088 the position as primary router.
3090 * Redefined the MAC generation keys in the protocol. The
3091 same key is not used anymore in both direction. Both
3092 direction will now use different keys for sending and
3093 receiving. This fixes a potential security flaw. This
3094 change causes incompatibilities in the protocol.
3096 * Redefined also the MAC computation from the packet.
3097 An packet sequence number is now added to the MAC
3098 computation. This prevents possible replay attacks against
3099 the protocol. This change too causes incompatibilities
3102 Added `sequence' field to the SilcPacketContext to hold
3103 the current sequence number for the packet.
3105 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Added `created' field to the SilcIDListData in the file
3108 silcd/idlist.h to indicate the time when the entry was
3111 * Added `created' field to the SilcChannelEntry too. Affected
3112 file silcd/idlist.h.
3114 * Added `creation_time' aguments to all the announcement functions
3115 in the server. If it is provided then only the entries that
3116 was created after the provided time frame are actually
3117 announced. Affected file silcd/server.[ch].
3119 * The protocol says that the Channel ID's IP address must be
3120 based on the router's IP address. Added check for this in
3121 the silc_server_new_channel when processing incoming New Channel
3122 Payload. Affected file silcd/packet_receive.c.
3124 * Print out the correct version with --version in SILC client.
3125 Affected file irssi/src/silc/core/silc-core.c.
3127 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Fixed WHOWAS command to check for completnes of the client
3130 entry always, not just when the command is coming from client.
3131 Affected file silcd/command.c.
3133 * Added new function silc_server_packet_queue_purge to purge the
3134 outgoing data queue to the network. After the function returns
3135 it is guaranteed that the outgoing packet queue is empty.
3136 Affected file silcd/packet_send.[ch].
3138 * Purge the outgoing packet queue in the rekey protocol's final
3139 callback to assure that all rekey packets go to the network
3140 before quitting the protocol. Affected file silcd/server.c.
3142 * Added silc_client_packet_queue_parse as similar function as
3143 in server to the client library. The affected file is
3144 lib/silcclient/client.c.
3146 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * Splitted silcd/server.c and created silcd/server_util.[ch]
3149 for utility functions.
3151 * Added new socket flag SILC_SF_DISABLED to indicate that the
3152 connection is open but nothing can be sent to or received from
3153 the connection. Affected file lib/silcutil/silsockconn.[ch].
3154 The checking for disabled socket is checked in the low level
3155 silc_socket_write and silc_socket_read functions.
3157 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Allow only nicknames and channel names that fits into the
3160 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3162 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3164 * When processing JOIN command reply in server check that if
3165 the channel exists in our global list we'll move it the local
3166 list. Affected file silcd/command_reply.c.
3168 * Fixed the check whether client is joined on the channel already
3169 in JOIN command. Affected file lib/silcclient/command.c.
3171 * Fixed the JOIN command reply to check whether the channel
3172 already exists. Affected file lib/silcclient/command_reply.c.
3174 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Added silc_ske_status_string to map the SKE error numbers
3177 to readable strings. The affected files are
3178 lib/silcske/silcske[_status].[ch].
3180 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Do not show the private channels on the WHOIS channel list
3183 as it is not allowed by the protocol. The affected file is
3186 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Assure that the packet length digged from the actual packet
3189 is something sensible in the silc_packet_decrypt_rest_special
3190 in lib/silccrypt/silcpacket.c.
3192 * Free and NULL the allocated pointer in silc_hmac_alloc if
3193 the HMAC allocation fails. The affected file is
3194 lib/silccrypt/silchmac.c.
3196 * Print the selected security properties to the log files in
3197 the server. Affected file silcd/protocol.c.
3199 * Add SKE's reference counter even if calling the completion
3200 callback manually. Otherwise it goes negative, although it
3201 does not cause any problems. The affected file is
3202 lib/silcske/silcske.c.
3204 * Remove the client entry with short timeout after giving the
3205 KILL command. Affected file lib/silcclient/command.c.
3207 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3208 case all found clients are already disconnected (WHOWAS would
3209 found them) in the server. Affected file silcd/command.c.
3211 * Update the last_receive (time of last data received) to be
3212 updated only when received private or channel message so that
3213 the idle time showed in WHOIS makes more sense.
3215 * Added boolean field `valid' in to the SilcClientEntry in the
3216 client library to indicate whether the entry is valid or not.
3217 This fixes the nickname change bug on channel when changing
3218 the nickname to be same than the old (like nick to Nick) the
3219 nickname formatter doesn't set the new nick anymore to Nick@host.
3220 Affected file lib/silcclient/idlist.[ch].
3222 * Now actually fixed the nickname changing on disconnection.
3223 Added new function silc_change_nick to the Irssi SILC Client.
3224 Affected file irssi/src/silc/core/client_ops.c,
3225 irssi/src/silc/core/silc-nicklist.[ch].
3227 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Check that the public key exists in the GETKEY command before
3230 trying to encode it. Affected file silcd/command.c.
3232 * Print some notifications on received public keys with GETKEY
3233 command in the Irssi SILC Client. Affected files are
3234 irssi/src/fe-common/silc/module-formats.[ch],
3235 irssi/src/silc/core/client_ops.c.
3237 * Use IDENTIFY command to resolve the server information in the
3238 GETKEY command instead of INFO command. Affected file
3239 lib/silcclient/command.c.
3241 * All command reply functions in the client library now calls
3242 the pending command reply callbacks even if an error has
3243 occurred. The server has done this a long time and now it was
3244 time to move the client library to this as well. Now all
3245 errors can be delivered back to the pending command reply
3246 callbacks if necessary. Affected files are
3247 lib/silcclient/command[_reply].[ch].
3249 * Change the nickname on disconnection back to the username
3250 because in reconnect the server will enforce it to it anyway.
3251 Affected file irssi/src/silc/core/silc-servers.c.
3253 * Fixed a config file parsing bug in the Irssi SILC client.
3254 Affected file irssi/src/silc/core/clientconfig.c.
3256 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * When printing the channel mode on JOIN, verify that the
3259 channel key and channel's HMAC are valid. Affected file
3260 irssi/src/silc/core/client_ops.c.
3262 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3265 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3266 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3268 * Removed channel key rekey task deleting from the function
3269 silc_server_save_channel_key. Affected file silcd/server.c.
3270 Added explicit timeout task context instead that is used to
3271 delete the task if we are registering a new task before the
3272 new task has elapsed.
3274 * When channel key rekey occurs the client library now saves
3275 the old channel key for a short period of time (10 seconds) and
3276 is able to use it in case some is still sending channel
3277 messages encrypted with the old key after the rekey. Affected
3278 file lib/silcclient/[idlist.h|client_channel.c].
3280 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Added check to the silc_server_new_id_real to not accept
3283 new ID if it is the sender's own ID. Affected file is
3284 silcd/packet_receive.c.
3286 * Assure that we do not announce ourself or the one we've
3287 sending our announcements when we're router and are announcing
3288 servers to our primary router. Affected file silcd/server.c.
3290 * Fixed silc_server_command_identify_check_client to assemble
3291 correct WHOIS packet. It send corrupted WHOIS packet and
3292 caused problem with router to router connections. Affected
3293 file silcd/command.c.
3295 Fixed also silc_server_command_whois_check the same way
3296 as for the IDENTIFY command.
3298 * Added new SilcIDListStatus to the server in the SilcIDListData
3299 structure. The status now includes the current status of
3300 the entry (like registered, resolved etc.). Affected file
3301 silcd/idlist.[ch]. Defined a bunch of different status types
3302 as well. This replaced the old boolean registered field as well.
3304 Added resolve_cmd_ident field to the SilcClientEntry structure
3305 too so that if the entry is for example being resolved so
3306 another command may attach to the same pending command reply
3307 without requiring to resolve the same entry again. This concept
3308 should optimize the WHOIS and the IDENTIFY resolving under
3309 heavy load by taking away unnecessary resolving for entries
3310 that are being resolved already.
3312 Added support for adding multiple pending commands for one
3313 command idenfier. Affected file silcd/command[_reply].[ch].
3315 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3316 before deleting the data. Otherwise the hash table will have
3317 freed data in comparison functions. Affected file is
3318 silcd/command_reply.c.
3320 * Fixed silc_idlist_replace_client_id to add the new entry to
3321 the cache with NULL nickname. Otherwise there will be invalid
3322 memory as the nickname after the nickname is freed. Affected
3323 file silcd/packet_receive.c.
3325 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3326 saved into wrong slots because the previous number of entries
3327 was not taken into account. Affected file silcd/idlist.c.
3328 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3330 * If we are router and we receive JOIN notify to a channel that
3331 does not have any users then notified client is marked as the
3332 channel founder, as it is it. The affected file is
3333 silcd/packet_receive.c
3335 * Added to the extended hash table API's table_del_*ext functions
3336 the destructor as argument too, so that the caller can decide
3337 which destructor to use or whether to use destructor at all.
3338 Affected file lib/silcutil/silchashtable.[ch].
3340 * Fixed ID Cache purging. It actually deleted the entries from
3341 the hash table after the data was freed. The hash table ended
3342 up comparing freed memory. The affected file is
3343 lib/silccore/silcidcache.c.
3345 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Fixed Irssi SILC client's KILL command's HELP syntax.
3349 * The USERS command now resolves the detailed user information
3350 if the userinfo field is missing. Affected file is
3351 lib/silcclient/command_reply.c.
3353 * Do not print error in silc_file_read if the read file does
3354 not exist. Just silently return NULL. Affected file is
3355 lib/silcutil/silcutil.c.
3357 * Fixed the silc_log_output to not wine about NULL filename
3358 and to not create some bogus " " filename. Affected file is
3359 lib/silcutil/silclog.c.
3361 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Fixed various printing bugs on the user interface in the
3364 Irssi SILC Client. Minor changes that were forgotten from
3367 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Fixed the configure.in.pre and the compilation and distribution
3370 environment to support the new autoconf 2.52. That version is
3371 now required to compile the CVS trunk.
3373 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3376 to generally parse user@fqdn format strings. Affected file
3377 lib/silcutil/silcutil.c.
3379 * Added nickname_format and nickname_force_format fields to the
3380 SilcClientParams structure. The first one defines the format
3381 for the nicknames that the library will enforce if the receives
3382 multiple same nicknames. The second one is boolean value and
3383 can be used to force the library to always enforce the format
3384 to the nicknames regardles whether there are multiple nicknames
3385 or not. This configurable formatting was employed to flexibly
3386 support accessing multiple nicknames from the user interface.
3387 The userinterface can now set the nicknames to what ever format
3388 they prefer. Affected file lib/silcclient/silcapi.h.
3390 Added function silc_client_nickname_format to the file
3391 lib/silcclient/idlist.c. It performs the nickname formatting.
3393 Added new field `hostname´ to the SilcClientEntry context.
3394 It holds the hostname of the client. Affected file is
3395 lib/silcclient/idlist.h.
3397 * Irssi SILC Client sets the nicknames in nick@hostn format.
3398 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3399 irssi/src/silc/core/silc-core.c.
3401 The WHOIS printing now also shows both the real nickname and
3402 the formatted nickname so that user knows how to access the
3403 user if there are multiple same nicknames cached. Affected
3404 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3405 printing formatting too to take the hostname now as a separate
3406 argument. The Affected file is
3407 irssi/src/fe-common/silc/modules-formats.[ch].
3409 * Changed the silc_client_get_clients_local to accept the formatted
3410 nickname as argument. It accepts the real nickname too but the
3411 formatted nickname can be used to find the true entry from
3412 multiple entries. Affected file lib/silcclient/silcapi.h and
3413 lib/silcclient/idlist.c.
3415 * Added nickname_format_parse field to the SilcClientParams.
3416 It is a callback function provided by the application to parse
3417 the nickname out of the formatted nickname string. The library
3418 calls it to get the nickname from the formatted string. Since
3419 the application generally knows better the format of the nickname
3420 string it parses it instead of the library, even though library
3421 encodes the formatted string. If the callback function is not
3422 provided then the library will use the string as is. The
3423 affected file is lib/silcclient/silcapi.h.
3425 * All the nickname strings passed to the client library in
3426 commands are now expected to be formatted nickname strings.
3427 If the command does not support the formatted nickname string
3428 it will assume that the sent string is the actual nickname.
3429 Affected file lib/silcclient/command.c.
3431 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3433 * Added public key authentication support to OPER and SILCOPER
3434 commands in the client library. Affected file is
3435 lib/silcclient/command.c.
3437 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3439 * Changed the get_auth_methdod client operation to be asynchronous.
3440 It can be async if the application resolves the authentication
3441 method from the server during the negotiation. Added new
3442 SilcGetAuthMeth completion callback that the application will
3443 call after resolving the authentication method.
3445 Added function silc_client_request_authentication_method that
3446 the application can use to resolve the authentication method
3447 from the server. Added also SilcConnectionAuthRequest callback
3448 that the library will call after the server has replied. The
3449 application can call this function if it does not know the
3450 current authentication method.
3452 Affected files are lib/silcclient/client.c and
3453 lib/silcclient/silcapi.h.
3455 * The Irssi SILC client now automatically resolves the authentication
3456 method incase any configuration information is not present (and
3457 currently there never is). The affected file is
3458 irssi/src/silc/core/client_ops.c.
3460 * Fixed public key authentication from the client library.
3461 Affected file lib/silcclient/protocol.c. Changed also the
3462 protocol specification about the public key authentication in
3463 the connection authentication protocol. The actual data to be
3464 signed is now computed with a hash function before signing.
3466 * Fixed the public key authentication from the server as well.
3467 Affected file silcd/protocol.c.
3469 * Removed the mlock()'s from the memory allocation routines.
3470 Affected file lib/silcutil/silcmemory.c. The ./configure does
3471 not check anymore for the mlock(). Affected file is
3474 * Fixed USERS command in server to allow the execution of the
3475 command for private and secret channels if the client sending
3476 the command is on the channel. Affected file silcd/command.c.
3478 * Fixed silc_client_get_clients_local to return the clients
3479 count correctly. It could return wrong value. Affected file
3480 lib/silcclient/idlist.c.
3482 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3485 types. The assembler optimizations seemed not to like 64-bit
3486 data types. The assmebler optimizations thus are now enabled
3487 also for BSD systems as opposed to only enable them for Linux.
3489 * Do not check for threads at all on BSD systems. Affected
3490 file configure.in.pre.
3492 * Removed -n and -h options from the Irssi SILC Client since
3493 they are not used in silc.
3495 * Fixed the prime generation to assure that the first digit
3496 of the generated random number is not zero since our conversion
3497 routines does not like number strings that starts with zero
3498 digit. If zero digit is seen the random number is regenerated.
3499 This caused some corrupted RSA keys when the zero first digit
3500 was met. Affected file lib/silcmath/silcprimegen.c.
3502 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Fixed WIN32 configuration in the ./configure script.
3505 Fixed to include xti.h on environments that has it.
3506 Patches by Carsten Ilchmann and andrew.
3508 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Changed the silc_id_create_client_id to be collision
3511 resistant. It is now assured that there cannot be created
3512 two same client ID's. I suspect that some weird bugs in
3513 the server were actually caused by duplicate Client IDs.
3514 Affected file silcd/serverid.[ch]. A router receiving
3515 new ID now also assures and informs the sending server
3516 if the ID caused collision.
3518 * Changed the silc_id_create_channel_id to also assure that
3519 there are no collisions.
3521 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * Statement about ignoring the Mutual Authentication flag when
3524 performing rekey with PFS was a bit misleading. It is ignored
3525 if it was set in the initial negotiation, it cannot be even
3526 set in the rekey. Fixed in the ke-auth draft. Started the
3527 new versions of the protocol drafts in the doc/.
3529 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Fixed a bug in silc_client_command_identify_save when saving
3532 new channel information. The channel name was no duplicated
3533 and caused crash on exit. Affected file is
3534 lib/silcclient/command_reply.c.
3536 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Fixed the getkey command handling in the server. Send just
3539 empty OK reply to the sender if the key could not be fetched
3540 (but everything else was ok, like the key just was not available).
3541 Changed the public key parameter to optional in the protocol
3542 specs so that empty OK reply can be sent. Affected file
3545 Added a message to Irssi SILC client to tell to user if the
3546 server did not return a public key.
3548 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Fixed a channel key regeneration bug. It registered new
3551 timeout tasks exponentially until all system resources were
3552 used. Affected file silcd/server.c.
3554 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Added the SILC Document generator to the scripts/silcdoc.
3557 It can be used to generate the Toolkit Reference Manual out
3558 of the source tree. Internally it will also use the RoboDoc
3559 generator now imported in util/robodoc.
3561 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Added couple of return's in rekey protocol if error orccurred
3564 during the protocol. The execution must be terminated.
3565 Affected file silcd/protocol.c. Also, terminate the protocol
3566 always with timeout.
3568 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * The client's Client ID was created initally from the wrong
3571 nickname (it could have been in format nick@host) in the
3572 silc_server_new_client. Affected file silcd/packet_receive.c
3574 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Added some SILC_LOG_ERROR's to various error conditions
3577 if client could not be added to ID cache. Affected files
3578 silcd/packet_receive.c and silcd/server.c.
3580 * When client's sock->user_data is freed, NULL also the
3581 client->router and client->connection pointers. Added check
3582 for these pointers being NULL to various places around the
3583 code. Affected file silcd/server.c.
3585 * Added client->data.registered == TRUE checks to various
3586 places around the code to assure that unregistered client's
3587 are not handled when it is not allowed. Affected file
3590 * Added `bool registered' fields to all
3591 silc_idlist_[server|client]_get_* routines to indicate whether
3592 the fetched client needs to be registered or not. Affected
3593 file silcd/idlist.[ch].
3595 * Add your own entry as registered to the ID cache in the
3596 server. Affected file server.c.
3598 * Fixed a bug in silc_server_new_server. The SilcServer was
3599 set as the new server's context instead of SilcServerEntry.
3600 This naturally caused some weird bugs.
3602 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Do not delete the channel rekey task when adding it
3605 for in silc_server_create_channel_key.
3607 * Changed the silc_server_create_channel_key to return
3608 TRUE or FALSE to indicate the success of the channel key
3611 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3613 * Fixed MSVC++ project files and added missing files to
3614 Makefiles under win32/.
3616 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Do not add TCP_NODELAY flag if the operating system
3619 does not have it defined. Affected files are
3620 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3622 * Fixed buffer overflow from Irssi SILC Client. Affected
3623 file irssi/src/fe-common/core/themes.c.
3625 * Fixed double free in client library in the file
3626 lib/silcclient/client.c when disconnecting from server.
3628 * Applied double free patch from cras to Irssi SILC client.
3629 Affected files irssi/src/core/[modules/expandos].c
3631 * Fixed the disconnection handling to Irssi SILC Client.
3632 The application must call silc_client_close_connection
3633 in ops->connect client operation in case of failure of
3634 the connection. Affected file is
3635 irssi/src/silc/core/client_ops.c.
3637 * Do not set sock->protocol to NULL in the function
3638 silc_client_close_connection after executing the protocol's
3639 final callback since the sock might not be valid anymore.
3640 Affected file lib/silcclient/client.c.
3642 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * Do not enable SILC_THREADS if the linking with libpthread
3645 did not happen. Affected file configure.in.pre.
3647 * Added notion to protocol specification that server must
3648 verify the sent authentication payload with CMODE when
3649 setting the channel founder key. Implemented it to the
3650 server. Affected file silcd/command.c.
3652 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Added _EXTRA_DIST SILC distribution variable to the
3655 distributions file. It is used to conditionally add extra
3656 files or directories to the specific distribution. Affected
3657 files ./prepare, Makefile.am.pre and distributions.
3659 Removed the `_' from the start of the distribution names.
3662 * Added README.WIN32 for instructions to compile the Toolkit
3665 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Fixed a double free in disconnection in the server. Affected
3668 file is silcd/server.c.
3670 * Fixed the lib/silcske/groups.c to work now also with GMP
3671 MP library. The string conversion did not work when using
3672 specific base and the base is indicated in the string as well.
3674 * Created win32/ directory which now includes MSVC++ specific
3675 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3676 It will appear only in the toolkit distribution
3678 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Changed the key material distribution function in case when
3681 the hash output is too short. The data is now concatenated
3682 a bit differently than it used to. Made the change to the
3683 SKE protocol specification.
3685 * Added better GMP detection to configure.in.pre. A patch
3688 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3690 * Fixed a minor bug in SKE that might cause some problem on
3691 some platforms. Affected file lib/silcske/silcske.c.
3693 * Added the cookie checking for initiator in the SKE. It checks
3694 that the responder returns the sent cookie unmodified. The
3695 affected file is lib/silcske/silcske.c. Added new SKE
3696 error type INVALID_COOKIE that can be sent during the
3697 negotiation. Fixed some memory leaks as well.
3699 * Added the "invalid cookie" error message to Irssi SILC client's
3702 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3704 * Added `task_max' field to the SilcClientParams to indicate
3705 the maximum tasks the scheduler can handle. If set to zero,
3706 default values are used. Affected file lib/silcclient/silcapi.h.
3708 * Fixed memory leaks in silc_client_close_connection. Affected
3709 file lib/silcclient/client.c.
3711 * Added silc_client_del_client_entry to client library to free
3712 all memory of given client entry. Affected file is
3713 lib/silcclient/idlist.[ch].
3715 * Added new functions silc_client_del_channel and
3716 silc_client_del_server to delete channel and server entries.
3717 Affected file lib/silcclient/[silcapi.h/idlist.c].
3719 * Removed silc_client_del_client_by_id from silcapi.h.
3721 * Fixed the INFO command to return the server's own info
3722 correctly when querying by Server ID. Affected file is
3725 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Removed the non-blocking settings in WIN32 code in the
3728 silc_sock_[read/write] and added SleepEx instead. Affected
3729 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3730 of input data is now checked with FIONREAD and ioctlsocket.
3732 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Call silc_schedule_task_del_by_context in the
3735 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3736 Affected file lib/silccore/silcprotocol.c.
3738 * Call silc_protocol_cancel for active protocols in the
3739 silc_server_close_connection if the funtion
3740 silc_server_free_sock_user_data has not been called.
3741 Affected file silcd/server.c.
3743 * Generic tasks cannot be deleted using the del_by_fd
3744 task deleting function since generic tasks does not match
3745 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3747 * Added a notion to SILCOPER help file that the SILCOPER works
3748 only on router server, not on normal server.
3750 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Added for WIN32 support for the new scheduler as well.
3753 Affected file lib/silcutil/win32/silcwin32schedule.c.
3755 * Fixed the SHA1 implementation to work on various platforms.
3757 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3760 API. It is part of the scheduler now. Everything else is
3761 as previously but some functions has changed their names.
3762 Checkout the lib/silcutil/silcschedule.h for the interface.
3763 Updated all applications to use the new interface. Affected
3764 files are lib/silcutil/silcschedule.[ch].
3766 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Found a bug in the SKE implementation. The HASH value,
3769 specified by the protocol, was not computed correctly. The
3770 public key of the responder was not added to the computation
3771 even though it is mandatory. Affected file lib/silcske/silcske.c.
3772 This unfortunately causes incompatibilities with older
3773 clients and servers.
3775 * Added WIN32 specific network init and uninit functions:
3776 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3777 the Winsock2. Affected file lib/silcutil/silcnet.h and
3778 lib/silcutil/win32/silcwin32net.c.
3780 * Set the socket always to nonblocking mode on WIN32 after
3781 reading data or writing data. Affected file is
3782 lib/silcutil/win32/silcwin32sockconn.c.
3784 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3786 * Fixed various compilation problems under WIN32. Affected
3787 files lib/silcutil/win32/silcwin32thread.c and
3788 lib/silcutil/win32/silcwin32schedule.c.
3790 * Removed all _internal.h #includes from public header
3791 files. Internal headers must never be included from
3794 Removed also the lib/silcske/payload_internal.h file.
3796 * All include files that may be needed (public and some others
3797 included by the public headers) by application developers are
3798 now copied to the ./includes directory. It does not copy any
3799 internal headers. Affected file Makefile.defines.pre and all
3800 Makefile.am's under lib/ and subdirs.
3802 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Do not change the ~/.silc directory's permissions automatically.
3805 Affected file irssi/src/silc/core/clientutil.c.
3807 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3809 * Do not cancel the protocol in silc_server_close_connection
3810 it might cause recursion. Now cancelled in the function
3811 silc_server_free_sock_user_data. Affected file silcd/server.c.
3813 * Fixed the silc_server_remove_clients_by_server to regenerate
3814 the channel keys correctly finally. Added also new function
3815 silc_server_remove_clients_channels to actually do it.
3816 Affected file silcd/server.c.
3818 * Fixed the silc_server_new_channel to not crash by giving
3819 wrong router to the new channel. Affected file is
3820 silcd/packet_receive.c.
3822 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3824 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3825 which is given as argument to the silc_client_alloc now.
3826 It can be used to configure the client and set various parameters
3827 that affect the function of the client.
3829 * The USERS command in server did not check whether the channel
3830 is private or secret. Affected file silcd/command.c.
3832 * Added new argument to the USERS command in protocol specification.
3833 The USERS command now can take the channel name as argument
3834 as well. Added support for this in client and server and
3835 updated the protocol specs.
3837 * Completed the GETKEY command in client. It can be now used
3838 to fetch also servers public key not only some clients.
3839 Affected files lib/silcclient/command[_reply].c.
3841 * Added silc_client_get_server to return server entry by the
3842 server name. Affected files lib/silcclient/silcapi.h and
3845 * Redefined the IDENTIFY command in protocol specification to be
3846 more generic. It now can be used to query information about
3847 any entity in the SILC Network, including clients, servers and
3848 channels. The query may be based either the entity's name
3849 or the ID. Added support for this in both client and server.
3851 Affected files silcd/command.c and lib/silcclient/command.c
3852 and command_reply.c.
3854 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3855 the _from_client and _from_server functions. Affected file
3858 * Added silc_client_get_channel_by_id_resolve to the file
3859 lib/silcclient/silcapi.h to resolve channel information by
3860 its ID. Added also silc_client_get_channel_by_id that
3861 does not resolve it from the server.
3863 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Added SilcServerEntry context into the client library
3866 to represent one server. The INFO command now allocates
3867 these to save the resolved server info. For now on the
3868 client library will also keep information about servers,
3869 connected and resolved with INFO.
3871 The INFO command now allocates the SilcServerEntry context
3872 and saves the server info there. The COMMAND_REPLY in
3873 the INFO now returns the parameters to application in
3874 same order as defined in the protocol specification.
3876 The entries are cached in the client->server_cache.
3878 * The INFO command is now issued after received the Client ID
3879 from the server. Affected file lib/silcclient/client.c.
3881 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3882 to the application as the mode changer might be server.
3883 It is guaranteed that NULL is not returned anymore to the
3884 application. Affected file lib/silcclient/client_notify.c.
3886 The ID Type is now also passed to the application so that
3887 it can check whether the returned entry is SilcClientEntry
3890 Added new function silc_client_get_server_by_id to return
3891 the server entry by ID. Affected files are the
3892 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3894 * Do not create the channel in the Irssi SILC Client when issuing
3895 the JOIN command but when received the sucessful JOIN command
3896 reply. Otherwise the channel might get created even though we
3897 could not join it. The Affected file is
3898 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3900 * Fixed a channel joining bug in router. The router must also
3901 check the channel modes, invite and ban lists etc. when serving
3902 the JOIN command sent by normal server. Affected file is
3903 silcd/command.c. The router now resolves the client's
3904 information from the server who sent the JOIN command if it
3905 does not know it, and processes the JOIN command only after
3908 * Changed the SilcCommandCb to take new argument; void *context2.
3909 Affected file lib/silccore/silccommand.h
3911 The second argument in the command callbacks in the server now
3912 includes the SilcServerCommandReplyContext if the command was
3913 called as pending command callback from the command reply.
3914 Otherwise it is NULL. When called as pending the status of the
3915 command reply will be checked and if it was erronous the
3916 error will be sent to the original sender of the command.
3917 This way the client always receives the error messages even
3918 though the server was actually the one who received the error
3919 when it resent the command to router, for example. Affected
3920 files silcd/command[_reply].[ch].
3922 * Fixed sending WHOWAS command's error message to client if
3923 the requested client could not be found. It was missing.
3926 * Changed the CMODE and CUMODE commands reply arguments in the
3927 protocol specification. The Channel ID is now sent in both
3928 of the commands to identify the channel. Implemented this
3929 new feature to the client and server. Affected files
3930 lib/silcclient/command_reply.c and silcd/command.c.
3932 * Made better checks for invite and ban lists in the JOIN
3933 command in server. Affected file silcd/command.c.
3935 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * The server now performs the incoming host IP/DNS lookup
3938 using the silc_socket_host_lookup and thus does not block
3939 the server anymore. Affected file silcd/server.c.
3941 * Completed the multi-thread support for SILC Scheduler in
3942 the lib/silcutil/silcschedule.c.
3944 * Fixed the configure.in.pre to detect the pthread correctly
3947 * Fixed a deadlock in silc_task_queue_wakeup in the file
3948 lib/silcutil/silctask.c.
3950 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Added new function silc_schedule_wakeup that is used in
3953 multi-threaded environment to wakeup the main thread's
3954 schduler. It needs to be used when a thread adds a new task
3955 or removes a task from task queues. After waking up, the
3956 scheduler will detect the task queue changes. If threads
3957 support is not compiled in this function has no effect.
3958 Implemented the wakeup mechanism to both Unix and WIN32
3959 systems. Affected files are lib/silcutil/silcschedule.[ch],
3960 lib/silcutil/unix/silcunixschedule.c and the
3961 lib/silcutil/win32/silcwin32schedule.c.
3963 * Added new function silc_task_queue_wakeup to wakeup the
3964 scheduler by the specified task queue. Affected file
3965 lib/silcutil/silctask.[ch].
3967 * The silc_socket_host_lookup_start now wakes up the scheduler
3968 after adding the timeout task. Affected file is
3969 lib/silcutil/silcsockconn.c.
3971 * The silc_socket_host_lookup is synchronous now if the threads
3972 support is not compiled in. However, the callback is still
3973 called asyncronously through the scheduler, anyway. Affected
3974 file lib/silcutil/silcsockconn.c.
3976 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3978 * Added new function silc_socket_host_lookup to perform
3979 asynchronous IP and FQDN lookups for the socket connection.
3980 Affected files lib/silcutil/silcsockconn.[ch].
3982 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3985 that may or may not compile the mutex support in.
3987 Changed the silc_mutex_alloc interface. It allocates the
3988 mutex now to the sent pointer and returns TRUE or FALSE.
3990 Affected file lib/silcutil/silcmutex.h.
3992 * Wrote the SILC Task Queue interface to support multi-threads.
3993 Affected file lib/silcutil/silctask.[ch].
3995 * Wrote the SILC Scheduler to support multi-threads. Affected
3996 file lib/silcutil/silcschedule.c.
3998 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4001 in lib/silcutil/win32/.
4003 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Defined SILC Mutex API and SILC Thread API and implemented
4006 them for Unix. Affected files are
4007 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4008 lib/silcutil/unix/silcunixmutex.c and
4009 lib/silcutil/unix/silcunixthread.c.
4011 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Fixed the silc_server_remove_clients_by_server's channel
4014 key re-generation. The hash table handling was incorrect
4015 and would not work with many channels. Affected file is
4018 * Fixed some memory leaks around the server code.
4020 * Rewrote the silc_server_get_users_on_channel to support IPv6
4021 based Client ID's. Affected file silcd/server.c.
4023 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4024 specification. However, a separate document must be written
4025 to define the detailed signing procedure and the payload
4026 associated with the flag. Defined the flag to the
4027 lib/silccore/silcchannel.h as well.
4029 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Changed the dynamic tables to static size tables in the
4032 lib/silccrypt/silchmac.c.
4034 * Removed GCC dependencies from the code. A patch by cras.
4036 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * Do not show the error "Error receiving packet bla bla"
4039 in server if it really was not an error (-2 means that reading
4040 is pending). Affected file silcd/server.c.
4042 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Fixed a possible crash in silc_server_remove_clients_by_server
4045 in silcd/server.c. Fixed there also some memory leaks.
4047 * Fixed the silc_idlist_replace_client_id. It could replace
4048 wrong key in the hash table. Affected file silcd/idlist.c.
4050 * Do not check whether there are global users on the channel
4051 if the channel->global_users is FALSE. Affected functions
4052 silc_server_remove_from_one_channel and
4053 silc_server_remove_from_channels in silcd/server.c. Also,
4054 do not check if the removed client is local as we can be
4055 sure that global client was not removed from the channel
4056 and checking for global users is not needed.
4058 * The silc_server_remove_clients_by_server now re-generates
4059 the channel keys correctly for those channels that had
4060 clients removed from them. Affected file silcd/server.c.
4062 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Found the reason of random crashes in the server. We weren't
4065 ignoring the SIGPIPE signal (which can be sent in write())
4066 and it crashed the server. Affected file silcd/silcd.c.
4068 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Assure that sock->user_data is not NULL in the function
4071 silc_server_packet_send in silcd/packet_send.c.
4073 * Disconnect the remote connection if it could not be added
4074 to any ID lists in the server. The affected file is
4077 * Check in silc_server_packet_send[_real/dest] that the
4078 socket is not disconnecting and ignore the data if it is.
4079 Affected file silcd/packet_send.c.
4081 * Define inline to __inline on native WIN32 compilation.
4082 Affected file includes/silcwin32.h.
4084 * Added some explicit type casts for inline code since MSVC
4085 require them. Affected files lib/silcutil/silcbuffer.h,
4086 lib/trq/silcdlist.h and lib/trq/silclist.h.
4088 * Print warning in log files from now on if the packet
4089 decryption fails. Affected file silcd/server.c.
4091 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4093 * Changed the `say' client operation's interface to accept
4094 new `type' argument to indicate the type of the message sent
4095 by the library. The application may filter the library's
4096 messages according the type. The affected file is the
4097 lib/silcclient/silcapi.h.
4099 * Added two new functions to lib/silcclient/silcapi.h:
4100 silc_client_del_client and silc_client_del_client_by_id.
4101 Affected file lib/silcclient/idlist.c.
4103 * Moved the clientincludes.h from includes/ to silc/ and
4104 serverincludes.h from includes/ to silcd/.
4106 * The modes for the CMODE and CUMODE are now passed as
4107 uint32 for application with COMMAND_REPLY. The affected
4108 file is lib/silcclient/command_reply.c.
4110 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4112 * /WHOIS without arguments shows client's own information.
4113 Affected file lib/silcclient/command.c.
4115 * Changed PING to not accept any arguments. The specs
4116 says that client can ping only the connected server so
4117 requiring an argument is not needed. Affected file is
4118 lib/silcclient/command.c.
4120 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4122 * Fixed a fatal bug in private message sending and reception
4123 encryption and decryption when using private message keys.
4124 The implementation was incorrect and did not follow the
4125 specification. It causd that some of the message were
4126 lost since it did not use the sending and receiving keys
4127 as the protocol suggests. This has been fixed and will cause
4128 incompatibilities with older clients when sending private
4129 message encrypted with private message keys. Affected files
4130 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4131 and various other in Irssi SILC Client.
4133 Added `responder' boolean argument to the functions
4134 silc_client_add_private_message_key[_ske] to indicate when
4135 the key is added as responder or initiator of the key
4138 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Removed the silc_ske_check_version function and created
4141 a SilcSKECheckVersion callback. Added also a function
4142 silc_ske_set_callbacks that is now used to set all SKE
4143 callbacks. The callback functions are not given to
4144 the SKE functions anymore, but this function is used to
4147 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4149 * Added `silc_version' argument to the silc_client_alloc
4150 to define the version of the application for the library.
4151 The library will use the version string to compare it
4152 against the remote host's (usually a server) version
4153 string. Affected file lib/silcclient/silcapi.h
4155 * Added the KE protocol context to Key Agreement context
4156 in client library so that we can abort the SKE if it
4157 is in process when we get timeout. Affected file is
4158 lib/silcclient/client_keyagr.c.
4160 * Do not resolve the client ID forever if it returns in the
4161 first time that such client does not exist. This was done
4162 for example with private message. Affected file is
4163 lib/silcclient/client_prvmsg.c.
4165 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * Do not add regex.h for WIN32. The affected file
4168 includes/silcincludes.h.
4170 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4171 not work yet 100%. It generates the DLL's automatically
4172 when compiling with --with-win32 under cygwin.
4174 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * lib/contrib/regex.c is not compiled on WIN32.
4178 * Added silc_net_get_socket_opt function to the
4179 lib/silcutil/silcnet.h.
4181 * Added includes/silcwin32.h for WIN32 specific includes
4184 * Do not use ptime structure or any of the posix process
4185 functions on WIN32 in lib/silccrypt/silrng.c.
4187 * Added silc_gettimeofday to provide generic function
4188 for struct timeval on all platforms. Added the function
4189 to lib/silcutil/silcutil.h.
4191 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4194 library as they clearly belong there. As a plus side we
4195 can make the actual socket connection routines platform
4198 Added also new generic function silc_socket_read and
4199 silc_socket_write (that used to be silc_packet_[read/write].
4200 The implementation of these are platform specific.
4202 * Added WIN32 specific routines of silc_socket_[read/write]
4203 to lib/silcutil/win32/silcwin32sockconn.c.
4205 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * Added preliminary support for native WIN32 compilation under
4208 cygwin (using the -mno-cygwin option for GCC) to the
4209 ./configure.in.pre. The --with-win32 now prepares the
4210 compilation for native WIN32.
4212 * Rewrote the SILC Scheduler interface in the file
4213 lib/silcutil/silcschedule.h. The scheduler is now context
4214 based and does not have anymore any global static scheduler.
4215 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4216 and created lib/silcutil/win32 directory for WIN32 based
4219 * Added Unix specific network routines to the
4220 lib/silcutil/unix/silcunixnet.c and the old
4221 lib/silcutil/silcnet.c includes now only generic routines.
4223 Added WIN32 specific network routines to the
4224 lib/silcutil/win32/silcwin32net.c.
4226 * Added Unix specific utility functions from the
4227 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4229 * Added WIN32 SILC Scheduler to the file
4230 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4233 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4235 * Do not handle JOIN notify in the server if the target client
4236 is not registered (idata->registered == FALSE). The affected
4237 file is silcd/packet_receive.c.
4239 * Update the nickrec->founder in event_cumode in the Irssi SILC
4240 client. Affected file irssi/src/silc/core/silc-channels.c.
4242 * Fixed the CUMODE_CHANGE notify handling in the server when
4243 server and router are announcing their clients on channels.
4244 Now the mode changes are saved and notified correctly. The
4245 affected file is /silcd/packet_receive.c.
4247 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4248 They really did not replace the cache entry in the ID Cache.
4249 Now they do that. Affected file silcd/idlist.c.
4251 * Fixed the KICK notify handling in the Irssi SILC client to
4252 update the channel records so that the kicked client does not
4253 appear to be on the channel. The affected file is
4254 irssi/src/silc/core/silc-channels.c.
4256 * Always update the conn->current_channel when executing command
4257 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4259 * Fixed the KILL notify handling in Irssi SILC client to remove
4260 the killed client on all channels.
4262 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Fixed the silc_parse_command_line to remove extra spaces
4265 from the start and end of the arguments. Affected file is
4266 lib/silcutil/silcutil.c.
4268 * Cancel and free any active protocol in the function
4269 silc_server_close_connection. Affected file silcd/server.c.
4271 * Cancel and free any active protocol in the function
4272 silc_client_close_connction. Affected file is
4273 lib/silcclient/client.c.
4275 * Do not execute the KILL command for clients that are in
4276 history (ie. they are not in the network). Affected file is
4279 * Fixed KILL notify handling, client does not crash anymore.
4280 Affected file irssi/src/silc/core/silc-channels.c.
4282 * Reduced the default packet buffer size from 2048 to 1024 in
4283 lib/silccore/silcpacket.c.
4285 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4286 counter to the SKE context that is incresed when the SKE library
4287 performs async operation outside the library. If the outside
4288 process frees the SKE context and FREED status will be set
4289 and the library will detect after the sync operation that the
4290 libary is freed. The affected files are
4291 lib/silcske/silcske[_status].[ch].
4293 * Resolve the client entry information in the function
4294 silc_client_channel_message to assure that NULL pointer is not
4295 passed as client entry to the application. */
4297 * Fixed the task timeout calculation to assure that there is
4298 never negative timeouts. The affected file is
4299 lib/silcutil/silcschedule.c.
4301 * Fixed the channel user mode notification sending in server.
4302 It was sent point-to-point to the router (or to server by router)
4303 but it needs to be destined to a channel. The routines now
4304 supports sending the channel user mode notifys to the channels
4305 when announcing clients and channels. Affected files are
4306 silcd/server.c and silcd/packet_receive.c.
4308 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4309 It did not actually replace the old channel entry in the cache.
4310 Affected file lib/silcclient/client_notify.c.
4312 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed a possible crash in silc_packet_send_prepare. It now
4315 assures always that there is enough space in the buffer and
4316 at the tail area of the buffer (for MAC).
4318 Fixed the inbound buffer reallocation in silc_packet_read.
4319 It was old code and did not handle the reallocation correctly.
4322 The affected file is lib/silccore/silcpacket.c.
4324 * Fixed buffer overflow in silc_parse_nickname in the file
4325 lib/silcutil/silcutil.c.
4327 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * make install generates new server keys only if there is not
4332 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4335 Added check that if the NOREPLY is set then we will not send
4336 the away message. This avoids infinite loop of away messages
4337 if both clients are away. The affected file is
4338 lib/silcclient/client_prvmsg.c.
4340 * Fixed client crash if /NICK was given without arguments.
4341 Affected file lib/silcclient/command.c.
4343 * Server does not send the invite list in INVITE command back
4344 to the client if the list was not altered. Added this notion
4345 to the protocol spec as well. Affected file silcd/command.c.
4347 Fixed possible crash in INVITE command by checking the
4348 value of silc_server_get_client_route command.
4350 * Fixed the INVITE notify type handling. The arguments are now
4351 taken in correct order and client does not crash. The affected
4352 file is irssi/src/silc/core/silc-channels.c.
4354 Removed the "Inviting xxx to channel" message from the
4355 client library away and let the application handle it.
4356 Affected file lib/silcclient/command.c. Added that message
4357 to Irssi SILC client's message formats.
4359 * Fixed CMODE command crash in client. It now checks the
4360 amount of arguments correctly and does not crash. The affected
4361 file is lib/silcclient/command.c.
4363 * Do not create new channel automatically in silc_channels_join
4364 but check whether the channel by that name already exists.
4365 Affected file irssi/silc/core/silc-channels.c.
4367 * Do not send the SERVER_SIGNOFF to router if the disconnected
4368 entity was the router. Affected file silcd/server.c.
4370 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4371 SILC client as it was missing from there.
4373 Added the handling of the KICK notify to the Irssi SILC client
4374 as it was missing. Added "you have been kicked" message to
4375 Irssi SILC client's message modules formats.
4377 Added the handing of the KILL notify to the Irssi SILC client
4378 as it was missing. Added the kill message module formats
4381 The affected file is irssi/src/silc/core/silc-channels.c.
4383 * The router did not save the channel mode the server announced.
4384 Affected file silcd/packet_receive.c.
4386 * Fixed a possible crash in INFO command in server. If the
4387 server did not provide the server info it crashed. Affected
4388 file silcd/command.c.
4390 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Fixed the GETKEY command in the server to check also the
4393 global list. Otherwise the GETKEY would not work correctly
4394 in normal SILC server. Affected file silcd/command.c.
4396 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Fixed GETKEY crash, it crashed if the command did not succseed.
4400 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4403 is now real and not just an macro interface to GMP.
4405 Removed the entire GMP from the source tree and imported new
4406 NSS MPI library instead. Reason for removing GMP is that it is
4407 extremely large and compiles extremely slow. The NSS MPI
4408 is only a few files and compiles in less than 10 seconds.
4409 The speed is also about the same as GMP. The MPI is imported
4410 to lib/silcmath/mpi.
4412 If the system has GMP installed we will still use the GMP.
4413 If it is not then the NSS MPI will be compiled.
4415 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Merged a long nickname (127 characters long) crash bugfix from
4418 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4420 * Merged a freed memory reference bugfix from Irssi CVS tree.
4421 Affected file irssi/src/core/commands.c.
4423 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Added the server's public key sving and verification to the
4426 server when performing the SKE. This was missing and the
4427 remote server's (or router's) public key was accepted without
4428 checking whether we have it previously or trust it at all.
4429 Affected file silcd/protocol.c.
4431 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Check in the silc_server_timeout_remote if protocol is active
4434 and make sure that the protocol's final callback is called so
4435 that all memory if freed. Affected file silcd/server.c.
4437 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * silc_server_whois_send_reply crashed the server if the nickname
4440 was 127 characters long. Affected file silcd/command.c.
4442 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Added sanity check to the silc_server_new_client. If the hostname
4445 is provided inside username then check that the provided hostname
4446 really is the same as the resolved one. If the hostname was not
4447 resolved then check it from the public key. Affected file is
4448 silcd/packet_receive.c.
4450 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4451 if the server disconnected us and the connection is not valid
4452 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4454 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4455 the library to the lib/silcutil/silcutil.[ch].
4457 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Close log file after open. Affected file
4460 lib/silcutil/silclog.c.
4462 * Check whether sock == NULL in silc_client_send_packet and return
4463 if it is. Affected file lib/silcclient/silcclient.c.
4465 * Check rec->entry == NULL in the Irssi SILC Client before
4466 sending the channel message. Affecte file is
4467 irssi/src/silc/core/silc-servers.c.
4469 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Merged a splitted window bugfix from Irssi CVS tree. The
4472 affected file is irssi/src/fe-text/textbuffer-view.c.
4474 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4475 It did not print nickname.
4477 * Improved the distributions system a bit.
4479 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4482 irssi/src/fe-text/gui-window.c.
4484 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4485 to in-active server. The affected file is
4486 irssi/src/silc/core/client_ops.c.
4488 * Resolve the client in USERS command reply if the entry does
4489 not have username resolved. The affected file is
4490 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4491 command to WHOIS command to really resolve stuff. The USERS
4492 is not used any more in any critical section so WHOIS can
4493 be used even though it might be slower than IDENTIFY.
4495 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4498 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Changed the protocol API a bit more consistent in the
4501 lib/silccore/silcprotocol.[ch].
4503 * Changed the following headers to ROBODoc format:
4505 lib/silccore/silcpayload.h
4506 lib/silccore/silcprotocol.h
4507 lib/silccore/silcsockconn.h
4509 All core library headers are now formatted.
4511 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Fixed a bug in Irssi SILC client; do not show that you are
4514 server/router operator if you really are not. Affected file is
4515 irssi/src/silc/core/client_ops.c.
4517 * Renamed silc_command_free_payload to silc_command_payload_free.
4518 Affected file lib/silccore/silccommand.h
4520 * Added silcmath.h to include the prototoypes of various routines
4521 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4524 * Changed the following headers to ROBODoc format:
4526 lib/silccore/silcchannel.h
4527 lib/silccore/silccommand.h
4528 lib/silccore/silcid.h
4529 lib/silccore/silcidcache.h
4530 lib/silccore/silcmode.h
4531 lib/silccore/silcnotify.h
4532 lib/silccore/silcpacket.h
4533 lib/silcmath/silcmath.h
4535 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Added checking to the server code not to start the server if
4538 ciphers and stuff are not configured properly. Affected files
4539 silcd/serverconfig.[h] and silcd/server.c.
4541 * Changed the layout of the header files of the public interfaces
4542 in the SILC libraries. The new layout supports ROBODoc
4543 documentation tool (and some others) so that it is easy to create
4544 a library reference manual. All the other headers and source
4545 code must still follow the CodingStyle document. Also source
4546 code must not include these ROBODoc stuffs, only the headers.
4547 Furthermore, all public interface headers must now be named
4548 by using `silc' prefix, example: silcapi.h, silccipher.h.
4549 Some files were renamed due to this. All the other headers
4550 must not be used as public interfaces. I will update the
4551 CodingStyle document later. Changed following headers, so far:
4553 lib/silcclient/silcapi.h
4554 lib/silccore/silcauth.h
4555 lib/silccore/silcprivate.h
4556 lib/silccrypt/silcdh.h
4558 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Removed silc_client_packet_send_flush from the client library
4563 as it is not needed. Affected file lib/silcclient/client.[ch].
4565 * Added printing of message of unresolved authentication method
4566 to the Irssi SILC client. Added it to the module formats.
4567 Removed the same message from the client library.
4569 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added new distribution feature, DISTLABEL. Every distribution
4572 can define own preprocessor label that can be used in the
4573 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4574 file distributions, acconfig.h.pre and prepare.
4576 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Added Makefile.defines_int to include the actual definitions
4579 for Makefile.defines.in. Tested the new distribution system,
4580 created distributions and tested installation.
4582 * Added AWAY message printing to the Irssi SILC client. Added
4583 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4585 * Added SCONNECT command to call the SILC's CONNECT command.
4586 Cannot use CONNECT directly since Irssi uses that internally.
4587 Affected file irssi/src/silc/core/silc-servers.c.
4589 Added ACTION local command. It is same as ME command but takes
4590 the channel as mandatory argument.
4592 Rewrote some of the Irssi's help files to suite for SILC
4595 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added Makefile.defines[.in] that should for now on be included
4598 in all Makefile.am file in the source tree. That file includes
4599 all common compilation definitions for SILC source tree.
4601 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Minor changes to the ./prepare script to change the package
4604 name according the distribution name to the configure.in.
4606 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Created new distribution system. Added file `distributions'
4609 that defines all the distributions that can be created out of
4610 the SILC source tree. The ./prepare script now reads that
4611 file to determine how to prepare the distributions. The
4612 first argument to the ./prepare is the name of the distribution
4613 and second is the version of the distribution. If given
4614 without arguments it creates the default (toolkit) distribution
4615 with the default version (defined in ./prepare).
4617 All Makefile.am files that are subject to the distributions
4618 are now named as Makefile.am.pre. These are ./Makefile.am
4619 and lib/Makefile.am. Others may be changed later.
4621 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Added invite list, ban list, some key management and connection
4624 error message printing to module formats in the Irssi SILC client.
4626 * Added new silc_client_set_away_message to set the away message
4627 that is back to the person who sent private message. The
4628 affected file lib/silcclient/silcapi.h and the
4629 lib/silcclient/client_prvmsg.c.
4631 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Fixed the private message sending in the Irssi SILC client,
4634 added local command KEY to the Irssi SILC client.
4636 Added key management and key agreement message formats to the
4637 irssi/src/fe-common/silc/module-formats.[ch].
4639 Added USERS (alias WHO) printing, server/router operator
4640 indication and LIST command printing to the module formats.
4642 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Fixed channel joining notify handling, cumode notify handling
4645 from Irssi SILC client.
4647 * Added SILC specific module-formats to the Irssi SILC client so
4648 that SILC specific message hilighting, colors etc is possible.
4649 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4651 Added channel mode, channel user mode, actions, notices,
4652 whois and whowas printing to the the module-formats.c.
4654 * Fixed a bug in channel deletion in the server. The channel
4655 is not left to the cache even if the channel founder auth mode
4656 is set when there are no users anymore on the channel. Affected
4657 file silcd/server.c.
4659 * The silc_net_localhost now resolves the entire hostname including
4660 the domain name. Affected file lib/silcutil/silcnet.c.
4662 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Changed the ask_passphrase client operation to be ascynchronous.
4665 It has now a completion callback and a context that the
4666 application must call after it has got the passphrase from
4667 the user. Affected files lib/silcclient/silcapi.h,
4668 lib/silcclient/protocol.c, lib/silcclient/command.c and
4671 Added SilcAskPassphrase callback that the application calls
4672 to deliver the passphrase to the library.
4674 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4675 The public key verification and especially a certificate
4676 verification is asynchronous procedure.
4678 Added new SILC_SKE_STATUS_PENDING status to indicate the
4679 request is pending and a callback will be called to finalize
4682 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4683 indicate that remote end did not send its public key (or
4684 certificate), even though we require it. Added check for this
4685 condition in the SKE. This was a security bug, now fixed.
4687 Defined new SilcSKEVerifyCbCompletion callback that is called
4688 when the verification process is completed.
4690 The affected files lib/silcske/silcske_status.h and
4691 lib/silcske/silcske.[ch].
4693 * Changed the verify_public_key client operation to be async
4694 as well. Defined SilcVerifyPublicKey callback that is used to
4695 indicate the success of the public key verification process.
4697 Changed the server and client to use the new async client
4700 * Changed the Irssi SILC client's internal scheduler to be called
4701 twice as many times as it used to be. As a result the client
4702 should be a bit faster now. Affected file is
4703 irssi/src/silc/core/silc-core.c.
4705 * Added support to Irssi SILC client of asynchronous public key
4706 verification and passphrase inquiry. Affected file is
4707 irssi/src/silc/core/silc-core.c.
4709 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Do not say "You have left channel %s" in client library.
4712 Moved it to the application. Affected files are
4713 lib/silcclient/command.c and silc/client_ops.c.
4715 * Fixed silc_client_get_clients. Command context was not
4716 duplicated and was freed memory in the callback. Affected
4717 file lib/silcclient/idlist.c.
4719 * Do not say "you are now talking..." on JOIN command in the
4720 client library. The appliation must handle it.
4722 * Do not say ".. changed topic to" in command reply in the
4723 client libary. The application must handle it.
4725 * Fixed TOPIC command sending in the client library.
4727 * Fixed a memory leak in silc_client_command_free in the file
4728 lib/silcclient/command.c.
4730 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Imported a modified version of Irssi client to the source tree.
4733 The Irssi will be used to create a new client called
4734 Irssi SILC. Imported to irssi/.
4736 Added silc_core_init_finish function to the Irssi. Affected
4737 file irssi/configure.in.
4739 A lot changes in the Makefile.ams around the irssi tree.
4741 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Do not rehash if the new size is same as the old size of the
4744 hash table, in the silc_hash_table_rehash*. The affected file
4745 lib/silcutil/silchashtable.c.
4747 * Replaced hash_table_del_by_context calls from the server
4748 (when channel->user_list and client->channels) to the
4749 hash_table_del as it is sufficient and faster.
4751 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added silc_hash_table_list, silc_hash_table_get and the
4754 SilcHashTableList structure to provide an alternative way to
4755 traverse the hash table. The affected files are
4756 lib/silcutil/silchashtable.[ch].
4758 * Changed the server's idlist routines to use the hash table
4759 routines to optimize the code.
4761 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Replaced the client entry's `channel' list and channel entry's
4764 `user_list' list to hash tables for optimized lookup. Changed
4765 the code to use the hash table interface around the code.
4766 Affected file lib/silcd/idlist.[ch].
4768 * Added `auto_rehash' boolean argument to the function
4769 silc_hash_table_alloc to indicate whether the hash table should
4770 auto-rehash when it thinks is appropriate time. It will
4771 increase the hash table size if the there is twice as much
4772 entries in the table than the size of the table, and will
4773 decrease the size if there are twice as less entries than
4774 the size of the table.
4776 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4780 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * silc_idcache_purge_by_context deletes the entry now by context
4783 as it is supposed to do. Affected file lib/silccore/idcache.c.
4785 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4786 client is not anymore valid (WHOWAS givens the info) and not
4787 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4789 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Removed the `data' and `data_len' arguments from the ID Cache
4792 interfaces and added `name' argument. ID Cache does not handle
4793 anymore the binary data only a names associated with given ID.
4795 * When hashing a Client ID with silc_hash_id the entire ID is
4796 not hashed anymore, instead only the hash of the Client ID is
4797 hashed. This way we can access the Client ID from the cache
4798 with Client ID but with the hash of the ID (which is a hash of
4799 the nickname) as well without any difference in performance.
4801 Added also silc_idcache_find_by_id_one_ext to do one on one
4802 searching when we have the actual ID. Added also function
4803 silc_hash_client_id_compare. The affected files are
4804 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4806 * When hashing the name associated with a ID it is always done
4807 in lowercase. This way we can access the cache without worrying
4808 about case-sensitivity, even though, for example nicknames are
4811 * Fixed a bug in server with channel message sending. It put
4812 wrong ID type as destination ID. The affected file
4813 silcd/packet_send.c.
4815 * silc_idcache_del_by_context now deletes from all hash tables
4816 by context. Affected file lib/silccore/idcache.c.
4818 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Changed the client library to use the new ID Cache interface.
4821 Changes around the source tree.
4823 * Added silc_hash_table_rehash_ext to rehash with specific
4824 hash function. Affected file lib/silcutil/silchashtable.[ch].
4826 * Added silc_hash_string_compare to compare two strings in the
4827 hash table. Affected file lib/silcutil/silcutil.[ch].
4829 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Added new function silc_idcache_del_by_context into the
4832 lib/silccore/idcache.[ch].
4834 * Changed the server's ID list routines to use the new ID Cache
4835 interface. Changes around the source tree.
4837 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Added silc_hash_table_del[_by_context]_ext functions in to the
4840 lib/silcutil/silchashtable.[ch].
4842 Removed silc_hash_table_find_all* routines and added new
4843 silc_hash_table_find_foreach to replace them.
4845 Added silc_hash_table_replace_ext function as extended
4846 replacing function. Separated the simple hash table interface
4847 from the extended hash table interface in the file
4848 lib/silcutil/silchashtable.h.
4850 * Fixed minor bugs and changed it to use some of the new
4851 hash table functions in lib/silccore/idcache.c
4853 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added new function silc_hash_table_find_all to return all keys
4856 in the hash table by the specified key. As the hash table is
4857 collision resistant it also makes it possible to have several
4858 duplicate keys in the hash table. This function may be used to
4859 find all of the keys from the hash.
4861 Added user_context arguments to the SilcHashFunction,
4862 SilcHashCompare and SilcHashDestructor to deliver user specified
4865 Added new fuctions silc_hash_table_find[_all]_ext to do
4866 extended lookup with specified hash and compare functions and
4867 specified user contexts.
4869 Added new function silc_hash_table_add_ext to add the key
4870 with specified hash function and user context.
4872 Added new function silc_hash_table_foreach to traverse all
4873 entrys in the hash table. Added SilcHashForeach callback
4876 Added new function silc_hash_table_del_by_context to delete
4877 the entry only if the context associated with the key matches.
4879 Affected files are lib/silcutil/silchashtable.[ch].
4881 * Removed silc_hash_[server/client/channel]_id and added just
4882 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4883 silc_hash_id_compare to compare two ID's using as the hash table
4884 comparison function. Added also silc_hash_data to hash
4885 binary data and silc_hash_data_compare to compare it.
4887 * Removed silc_idlist_find_client_by_hash as it is not needed
4888 anymore. Affected file silcd/idlist.[ch].
4890 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4891 to use internally the SilcHashTable. The new ID Cache is a lot
4892 faster than the old one. Some of the ID Cache interface was also
4893 rewritten and obsolete and stupid functions were removed.
4895 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Added entry_count field to the SilcHashTable to keep the number
4898 of the entries in the table. Implemented the function
4899 silc_hash_table_rehash. Added new function
4900 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4902 Fixed a minor bug in silc_hash_table_free.
4904 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4905 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4906 into the lib/silcutil/silcutil.[ch].
4908 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Implemented a collision resistant hash table into the
4911 lib/silcutil/silchashtable[ch]. See the header and the source
4912 for the SilcHashTable API.
4914 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Merged dotconf version 1.0.2 into lib/dotconf.
4918 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Do not compile anything in lib/silcsim/* if the SIM support
4921 is not enabled. The tree should now compile without problems
4924 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Compiled the SILC under cygwin. Compiled and tested briefly
4927 without problems. More tests needed. The SIMs didn't compile
4930 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4932 * Fixed possible crash in silc_get_username in the
4933 lib/silcutil/silcutil.c.
4935 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed a va_arg in silc/client_ops.c.
4939 * Oops, RC5 routines were named AES and caused some problems
4940 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4942 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Added new SilcIDIP structure into the lib/silccore/id.h and
4945 replaced the old `ip' fields from all SILC ID's to that type.
4946 This is a step towards IPv6 support.
4948 The silc_id_get_len takes now the ID as an extra argument.
4949 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4950 both IPv4 and IPv6 based ID's.
4952 The affected files are lib/silccore/id.[ch] and other files
4953 around the tree using these routines.
4955 * Removed the ID length arguments in server from various
4956 silc_server_send_notify_* routines -> they are not needed
4959 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Fixed memory leak in silc_encode_pem_file in the file
4962 lib/silcutil/silcutil.c.
4964 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Check minor version as well in the SKE. Affected files are
4967 silcd/protocol.c and lib/silcclient/protocol.c.
4969 * Added --identifier option to the server so that an identifier
4970 can be when creating the public key for the server. Affected
4971 file is silcd/silcd.c.
4973 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4974 lib/silccrypt/silcpkcs.c.
4976 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Register default ciphers and stuff when using -C option with
4979 the server. Affected file sildc/silcd.c.
4981 * Put back the servers public key filename format, it is better
4982 than the new one. For now, the client keys are saved with the
4983 new filename format. The affected file silc/client_ops.c.
4985 * Implemented the Cipher API for the rest of the ciphers that
4986 did not implement it or implemented it the wrong way.
4988 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Register default ciphers and stuff when using the -S option
4991 in the client. Affected file silc/silc.c. Same also when
4992 creating new key pair with -C option.
4994 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Fixed the silc_verify_public_key client operation function to
4997 save the public keys differently. The fingerprint is now
4998 used as filename and not the hostname. This way also the
4999 client keys are saved uniquely and not with hostnames. The
5000 affected file is silc/client_ops.c.
5002 * Trimmed the silc_hash_fingerprint function to remove extra
5003 whitespaces from the end of the fingerprint. The affected
5004 file is lib/silccrypt/silchash.c.
5008 * Added silc_cipher_register_default function to register all
5009 default ciphers. It can be used when configuration files
5010 does not exist and the application does not want any specific
5011 ciphers in any specific order.
5013 The SilcDList is now used as silc_cipher_list dynamically
5014 allocated cipher list. Removed the static list all together
5015 and now all ciphers must be allocated to the dynamic list.
5016 The silc_cipher_alloc routine was changed to check only the
5019 All silc_cipher_* routines that used to return int returns
5022 The affected files lib/silccrypt/silccrypt.[ch].
5024 * The same thing was done to silc_hash_* as for silc_cipher_*
5025 routines. Affected files lib/silccrypt/silchash.[ch].
5027 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5028 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5029 Added also silc_pkcs_[un]register[_default] functions.
5030 Removed the data_context from the PKCS API.
5032 * Added silc_hmac_register_default function to register default
5033 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5034 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5035 to unregister all hmacs at once.
5037 * Register the default ciphers, hash functions, PKCSs and HMACs
5038 if client's configuration file does not exist. The affected
5041 * The client did not load the hash functions from the SIM
5042 modules at all. Added support for this. Affected file is
5043 silc/clientconfig.c.
5045 * When decoding public key with silc_pkcs_public_key_decode, check
5046 the supported algorithm only if PKCS are registered. Affected
5047 file lib/silccrypt/silcpkcs.c. The same was done with the
5048 silc_pkcs_private_key_decode.
5050 * Fixed the SILC List routines to keep the list always in order.
5051 It used to change the list's order when traversing the list but
5052 not it preserves the order. Affected file lib/trq/silclist.h.
5054 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added the client library to use the SilcSocketConnection's
5057 reference counter (by silc_socket_dup) to prevent the bug that
5058 the socket object may be freed underneath async operation.
5060 * The name resolv library checking fixes in the configure.in.pre.
5063 * Created new version of the protocol drafts for future
5064 development. The -03 drafts are the ones that will be changed
5065 in the trunk now and the -02 will remain as they are.
5067 * Send list of CUMODE notifys to the router when announcing
5068 the channel users to the router. Affected file silcd/server.c.
5069 If the router receiving channel founder CUMODE for a channel
5070 that already has channel founder it will send CUMODE notify
5071 to the sender to remove the channel founder rights from the
5072 announced client. Affected file silcd/packet_receive.c.
5074 * The CUMODE notify may now use Server ID as well as the entity
5075 who changes the mode. Updated protocool specs.
5077 * Updated INSTALL and README files.
5079 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * New web pages in the http://silc.pspt.fi. The pages was
5086 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Implemented the [DenyConnectin] config section in the server.
5089 Added silc_server_config_denied_conn to check whether incoming
5090 connection is denied. Affected file silcd/serverconfig.[ch].
5092 * Do not check the ports when checking the incoming configuration
5093 data if the port is 0, meaning any. Affected file is
5094 silcd/serverconfig.c.
5096 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Fixed buffer overflow in silc_string_compare in the file
5099 lib/silcutil/silcutil.c.
5101 * Fixed double free in silc_server_command_leave in the file
5104 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Fixed the version checking in the server. Affected file is
5109 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Fixed the configuration data fetching when accepting new
5112 connections in the server. Affected file silcd/server.c.
5114 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Added `sender_entry' argument to the function
5117 silc_server_packet_relay_to_channel so that we can check
5118 whether some destination actually belongs to the same route
5119 the sender belongs (ie, we must not resend the packet to the
5120 sender). Affected file silcd/packet_send.[ch].
5122 * Added `servername' field to the SilcClientEntry in the server
5123 to hold the name of the server where client is from. Affected
5124 file is silcd/idlist.h.
5126 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Moved the channel message encrypting in the router betwen
5129 router connections from silc_server_channel_message to the
5130 silc_server_packet_relay_to_channel since we want to check
5131 whether we have anybody channel before encrypting anything.
5132 Affected files silcd/packet_[receive/send].c.
5134 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Fixed the [AdminConnection] server config section to support
5137 multiple entries. Affected file silcd/serverconfig.c.
5139 * Added support into the server to check the validity of the
5140 incoming connection before executing any KE or authentication
5143 * The connection configuration is now saved to the KE and
5144 connection auth protocol contexts and not fetched anymore in
5145 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5147 * The local hosts listenning address and port is also resolved
5148 now when starting the server. We want to have the socket object
5149 to include the real address and port for the listener. Added
5150 new function silc_net_check_local_by_sock into the files
5151 lib/silcutil/silcnet.[ch].
5153 * Fixed a broadcast bug in server -> do not broadcast if we
5156 * Fixed a routing bug. Do not route broadcast packets ever.
5157 Broadcast packets must be processed always and not routed since
5158 they may be destined to some other host than yourself and thus
5159 would get routed without no good reason. Affected file is
5162 * Added function silc_server_config_is_primary_route to check
5163 whether primary router connection has been configured (a router
5164 configuration that we are initiating). If there is not, we
5165 will assume that there is only two routers in the SILC network
5166 and we will use the incoming router connection as our primary
5167 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5169 * Changed the order of the broadcasting. Broadcast _after_ the
5170 packet has been processed not before. Affected file is
5173 * Fixed a [ClientConnection] parsing bug. The port was never
5174 parsed correctly thus resulting to port 0. Affected file
5175 silcd/serverconfig.c.
5177 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5178 argument and did not set the broadcast packet flag. Affected
5179 file silcd/packet_send.c. Fixed same bug in the function
5180 silc_server_send_notify as well.
5182 * If we receive NEW_ID packet for our own ID in the server, ignore
5185 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Removed the nickname from the Private Message Payload.
5190 Updated the code and the protocol specs.
5192 * Updated protocol specs for submitting to the IETF.
5194 * Tweaked the Random Number Generator a bit. Affected file
5195 lib/silccrypt/silcrng.c. Exported a new function
5196 silc_rng_[global]_add_noise which can be used to add more
5199 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Do not parse packets with different timeout when protocol
5202 is active -> may cause problem with rekey. Affected file
5205 * When server receives signoff notify it must not create
5206 new channel key if the client is on any channels since the
5207 sender of the signoff notify will create it.
5209 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added printing of error messages during SKE protocol from the
5212 failure packet sent by server during SKE. Affected file
5215 * Removed the client's failure_callback handling with timeout
5216 and handle it immediately when received.
5218 * The SKE library returned wrong type in SUCCESS and FAILURE
5219 packets. They must be 32 bit MSB not 16 bit MSB.
5221 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Ok, rewrote the logic of the re-key and now it seems to work.
5224 I tested it on high traffic with frequent re-keys without
5225 problems. Added hmac_receive (and renamed hmac to hmac_send)
5226 in SilcClientConnection in lib/silcclient/client.h and
5227 in SilcIDListData in silcd/idlist.h. Also, removed the
5228 SilcPacketParserContext's cipher and hmac fields as they are
5229 not needed anymore and actually caused some problems when
5230 the ciphers and hmac's changed underneath the packet parser.
5232 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * If re-key protocol is active then process the incoming packets
5235 synchronously since we must assure that icoming packets encrypted
5236 with the old key is processed before the new keys is set to
5237 use. This is true other packets than for REKEY packets.
5238 Affected file silcd/server.c. The same was done to client library
5239 as well, affected file lib/silcclient/client.c.
5241 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Fixed bug in client and server to accept the force send if
5244 the packet is send from silc_[server/client]_packet_process
5245 function. Otherwise the packets are never delivered, oops.
5247 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Disable force sending of packets when REKEY protocol is active.
5250 We must assure that no packet is sent directly when rekey is
5251 performed. All packets must be sent through packet queue.
5252 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5253 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5254 function is silc_[server/client]_packet_send_real to check
5257 * Replaced the SIM paths from example config files to
5258 /usr/local/modules. Also, make install creates now
5259 /usr/local/silc/logs directory to hold all the SILC server
5262 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Made the configure.in.pre work on Solaris. Patch by salo.
5266 * Made all ciphers compatible with non-x86 machines. Defined
5267 CBC mode macros into lib/silccrypt/ciphers_def.h.
5269 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Fixed the make install.
5273 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * When MAC computation fails the silc_packet_decrypt returned 0
5276 even though it was supposed to return -1. Fixed this. The
5277 affected file is lib/silccore/silcpacket.c.
5279 * Do not replace the config files in /etc/silc (in make install)
5280 if they already exist. Affected file ./Makefile.am.
5282 * Do not send re-key packets immediately but through packet queue.
5283 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5285 * Changed silc_net_check_host_by_sock to return FALSE if the
5286 IP/DNS could not be resolved. Though, it returns the IP address
5287 now even if it could not resolve it (but returns also FALSE).
5288 Affected file lib/silcutil/silcnet.[ch].
5290 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Added silc_pkcs_decode_identifier to decode the public key's
5293 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5294 Added also silc_pkcs_free_identifier. Added also new context
5295 SilcPublicKeyIdentifier.
5297 * Added -S option to the silc client. It is used to dump the
5298 contents of the specified public key file.
5300 * Changed the PKCS api to return the public key length when
5301 setting the public key.
5303 * Fixed a fatal bug in the public and private key file loading.
5304 Affected file lib/silccrypt/silcpkcs.c.
5306 * Execute the packet parsing for client with zero (0) timeout
5307 if the protocol is active. Affected file silcd/server.c.
5309 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Made the key generation options to the silcd program. Added
5312 -C option, equivalent to client's option.
5314 * Added new [ServerKeys] config section to the server. It
5315 configures the server's public and private key.
5317 * Defined generic Public Key Payload into the protocol
5318 specification to send specific type of public keys and
5321 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5322 public key or certificate.
5324 * Implemented the GETKEY command to the server and to the
5325 client library and on user interface.
5327 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Made preliminary `make install' work.
5331 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added SilcServerRekey context into silcd/idlist.h.
5335 * Added the PFS support as defined in the specification to the
5336 SKE protocol. Affected files lib/silcske/*.c.
5338 * Added `ske_group' field to the SilcServerRekey context to hold
5339 the number of the SKE group that is used with PFS in re-key.
5340 Affected file silcd/idlist.h.
5342 * Added PFS re-key support to the server. Affected file is
5345 * Added silc_protocol_cancel to cancel execution of the next
5346 state of the protocol. Affected file is
5347 lib/silccore/silcprotocol.[ch].
5349 * Added the re-key support with and without PFS to the client
5350 library. Re-key is performed once in an hour, by default.
5352 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5353 Added silc_client_rekey_callback and silc_client_rekey_final.
5354 Affected files are lib/silcclient/protocol.[ch] and
5355 lib/silcclient/client.[ch].
5357 * Removed the `hmac_key' and `hmac_key_len' fields from the
5358 SilcClientConnection structure; not needed. Affected file is
5359 lib/silcclient/client.h.
5363 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Do not ask whether user wants to use the negotiated private key
5366 for private messages, just use it. Affected file is
5367 silc/local_command.c.
5369 * Added `send_enc_key' and `enc_key_len' fields to the
5370 SilcIDListData structure since they are needed in the re-key
5371 phase. Affected file is silcd/idlist.[ch].
5373 * Implemented the simple re-key protocol into the server.
5374 Affected files silcd/server.c and silcd/protocol.[ch]. The
5375 re-key will be performed once in an hour, by default.
5377 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5378 Added silc_server_rekey, silc_server_rekey_callback and
5379 silc_server_rekey_final.
5381 * Removed Tunneled flag from the protocol. Updated the code
5382 and the specifications.
5384 * Adde `pfs' field to the SilcIDListData to indicate whether
5385 the PFS is to be performed in the re-key. Affected file is
5388 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5391 int64 of at least the xintXX size. If void * is less that 4
5392 bytes uint32 * will be used. Defined bool as boolean.
5394 * Changed _ALL_ unsigned long and unsigned int to uint32,
5395 unsgined short to uint16 in the source tree.
5397 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5398 not handle clients that has entry->data.registered == FALSE.
5399 They are not in the network anymore. Affected file is
5402 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Implemented the sending of the SERVER_SIGNOFF notify in the
5405 server. Affected file is silcd/server.c.
5407 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5408 Added also silc_notify_payload_encode_args into the
5409 lib/silccore/silcnotify.[ch].
5411 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5412 Affected file silcd/packet_receive.c.
5414 * Implemented the SERVER_SIGNOFF notify handling in the client
5415 library. Affected file lib/silcclient/client_notify.c. Also,
5416 implemnted the printing of the SERVER_SIGNOFF info to the
5417 application. Affected file silc/client_ops.c.
5419 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5420 if the deleting was successful. Affected file silcd/idlist.[ch].
5422 * Added support for public key authentication in the connection
5423 authentication protocol in the client library. Affected file
5424 lib/silcclient/protocol.c.
5426 * Changed the server's silc_idlist_get_clients_by_* interface
5427 to support already allocated array so that new entries may be
5428 added to pre-allocated array. Affected file silcd/idlist.[ch].
5429 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5430 and command replies.
5432 * All command reply functions in the server now calls the
5433 pending command callback even if error occured. This way the
5434 error will be delivered to the client as well. Affected files
5435 silcd/command.c and silcd/command_reply.c.
5437 * Fixed INFO command to return local server's info if no server
5438 was provided. Affected file lib/silcclient/command.c.
5440 * Removed RESTART command for good. Updated the code and the
5443 * Rewrote parts of the task system. It is a bit simpler now.
5444 Removed unsued task priorities. The affected files are
5445 lib/silcutil/silctask.[ch].
5447 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Moved the USERS printing from the library to the application.
5450 Affected files lib/silcclient/command.c and silc/client_ops.c.
5452 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Added channel key re-key support. The re-key is perfomed
5457 only by the router and is done once in an hour. Added `rekey'
5458 field to the SilcChannelEntry in the server. Affected files
5459 silcd/server.c and silcd/idlist.h.
5461 * Added silc_task_unregister_by_context into the file
5462 lib/silcutil/silctask.[ch].
5464 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Added SILC_UMODE_GONE mode to indicate when the client is not
5467 present in the SILC network. Added also support to the local
5468 command AWAY that will set this mode. Added support of showing
5469 "xxx is gone" in WHOIS command. The USERS command shows the
5470 gone status as well.
5472 * Fixed setting server and router operator privileges in the
5473 server's UMODE command. Affected file silcd/command.c.
5475 * Merged the SKE KE1 and KE2 payloads into one payload. The
5476 new KE payload is equivalent to the old KE2 payload.
5478 Cleaned up the SKE Start Payload parsing. It now uses the
5479 simple buffer unformatting to do the parsing. A lot faster
5482 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5483 to the SKE that is used to indicate whether both of the SKE
5484 parties should perform authentication. By default only the
5485 responder performs authentication. By setting this flag also
5486 the initiator must do authentication. By default it is unset
5487 since in normal SKE case, client to server connection, only
5488 the responder should do authentication. When doing SKE between
5489 two clients both should perform authentication. Updated the
5490 code and the protocol specs.
5492 * A little fix to IDENTIFY command in the server. Search the
5493 client first by hash not nickname. Affected file is
5496 * Fixed the silc_client_close_connection to support closing
5497 the client to client connections wihtout deleting too much
5498 data. Affected file lib/silcclient/client.c.
5500 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5501 are received if protocol used to be active but is not anymore
5502 the application would crash due to NULL pointer dereference.
5503 Affected files silcd/server.c and lib/silcclient/client.c.
5505 * Added `hash' field to the SilcClientConnection to include
5506 the hash function negotiated in the SKE protocol.
5508 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5509 to set the channel founder authentication data. A client can
5510 claim the founder rights later by providing the authentication
5511 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5512 This way the channel founder can regain the channel founder
5513 privileges even it is left the channel. This works only on
5514 local server and the client must be connected to the same
5515 server to be able to regain the founder rights. Updated the
5516 protocol specs accordingly.
5518 Added support to the CMODE command in the client to set the
5519 founder auth data. Read the README to see how to set it.
5521 Added support to the CUMODE command to claim the founder
5522 rights. Read the README to see how to do it.
5524 Added support for the founder authentication to the Channel
5525 Entry in the server. Affected file silcd/idlist.h.
5527 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5528 server's CMODE command. Affected file silcd/command.c.
5530 * Added the following new functions into lib/silccore/silcauth.[ch]:
5531 silc_auth_get_method and silc_auth_get_data.
5533 * The server now saves the remote hosts public key to the
5534 SilcIDListData pointer. Affected file silcd/protocol.c.
5536 * The normal server now does not remove the channel entry from
5537 the cache if the founder authentication data is set. It used
5538 to remove it if the founder was the last one on the channel on
5539 the server and left the channel. The auth data is saved and
5540 if the channel is re-joined later the old entry is used with
5541 the old auth data. Affected files silcd/command_reply.c and
5544 * Removed the `pkcs' field from the SilcIDListData structure
5545 in the server; it is not used. Affected file silcd/idlist.h.
5547 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Fixed packet processing on slow links. Partial packets were
5550 never re-processed because the incoming data buffer was cleared
5551 by the application. Application must not directly clear the
5552 sock->inbuf, the packet processing routines handle it. Fixed
5553 this in client library and in server.
5555 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Fixed the WHOIS and IDENTIFY send reply function to really
5558 check whether to send list or just one entry. Affected file
5561 * Cleaned up the LEAVE command's channel key distribution. The
5562 affected file silcd/command.c.
5564 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5565 can enforce the channel mode as well. In that case the ID
5566 includes the ID of the server. The code now enforces the
5567 mode change if the router have different mode than the server.
5569 * The notify client operation with CMODE_CHANGE notify can now
5570 return NULL client_entry pointer if the CMODE was not changed
5571 by client. Application must check for this.
5573 * Added <Server ID> argument to INFO command to support server
5574 info fetching by Server ID.
5576 * Added silc_server_announce_get_channel_users to get assembled
5577 packets of channel users of the specified channel. Affected
5578 file silcd/server.[ch].
5580 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5581 was freed underneath the ID Cache.
5583 * Re-announce clients when the server received CHANNEL_CHANGE
5584 notify from the router. Affected file silcd/packet_send.c.
5586 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5589 crashed since it did not handle the fact that there is no cipher
5590 called "3" and didn't check the error condition. Now fixed.
5592 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5593 flag. It can be used to send message requests.
5595 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Implemented the RESTART command in the client.
5599 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5600 notice type messages. Added notice printing to the user
5603 * The channel keys are not re-generated if the channel's mode
5604 is PRIVKEY, ie private key on the channel exists. Affected
5605 files silcd/server.c and silcd/command.c.
5607 * Fixed a little bug in channel message delivery when channel
5608 private keys are set in the server. Affected file is
5609 silcd/packet_send.c.
5611 * Changed the setting on channel->on_channel = TRUE from the
5612 silc_client_save_channel_key to the JOIN command reply. The
5613 key payload is not received if the private channel key is set.
5614 Affected file lib/silcclient/command_reply.c and the
5615 lib/silcclient/client_channel.c.
5617 * When the CMODE_CHANGE notify is sent and the channel private
5618 key mode is removed the channel key must be re-generated in
5619 other cells as well. Added this support for the router in the
5620 silcd/packet_receive.c.
5622 * Added new local command NOTICE to send notice message on
5623 channel. Affected file silc/local_command.[ch].
5625 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Added new local command ME to the client. It is used to send
5628 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5629 some action. Affected file silc/local_command.[ch].
5631 * Changed channel_message and private_message client operations
5632 to deliver the message flags to the application. Added also
5633 the `flags' arguments to the silc_client_send_channel_message
5634 and silc_client_send_private_message functions. Affected file
5637 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Redefined the Private Message Payload to support private message
5640 keys and to support the new private message flags. Updated
5641 the protocol specs. Flags makes it possible to have for example
5642 CTCP style messages.
5644 * Added new type SilcPrivateMessagePayload and defined an API
5645 for it in the lib/silcclient/silcprivate.[ch].
5647 * Tested private message private keys successfully. Tested the
5648 private message key set, unset and list commands with the new
5651 * Redefined the Channel Message Payload to include the channel
5652 message flags (equal with private message flags) to support
5653 for example CTCP style messages.
5655 * Defined some of the message (for channel and private message)
5656 flags. Updated the protocol specs and added the flags to the
5657 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5659 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Added SilcKeyAgreementStatus type to the key agreement routines
5662 to indicate the current status and error if one occured.
5663 The status types are defined in the lib/silcclient/silcapi.h.
5665 * Added new local command KEY that is used to set and unset private
5666 keys for channels, set and unset private keys for private messages
5667 with remote clients and to send key agreement requests and
5668 negotiate the key agreement protocol with remote client. The
5669 key agreement is supported only to negotiate private message keys,
5670 it currently cannot be used to negotiate private keys for channels,
5671 as it is not convenient for that purpose.
5673 * Fixed a minor pending callback setting bug in the function
5674 silc_client_get_client_by_id_resolve, now the function works.
5675 Affected file lib/silcclient/idlist.c.
5677 * Added function silc_net_get_local_port to get local bound
5678 port by socket. Added to lib/silcutil/silcnet.[ch].
5680 * Added `sockets' and `sockets_count' fields to the SilcClient
5681 object. They hold the sockets of the listenning sockets in
5682 the client. Listenning sockets may be for example the key
5683 agreement server. Affected file lib/silcclient/client.[ch].
5684 Added functions the silc_client_add_socket and the
5685 silc_client_del_socket. They are exported to the application
5688 * Added ~./silc/clientkeys to support other client's public keys.
5690 * Renamed verify_server_key client operation to verify_public_key
5691 and added one argument to indicate the type of the connection
5692 (server, client etc.).
5694 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added silc_server_connection_auth_request to handle the
5697 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5698 silcd/packet_receive.[ch].
5700 * Added silc_server_send_connection_auth_request into the
5701 silcd/packet_send.c to send the connection auth request packet.
5703 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5706 * Fixed the public key authentication in responder side in the
5707 server. The `auth_data' pointer includes the SilcPublicKey
5708 not the path to the public key. Affected file silcd/protocol.c.
5710 * Implemented the public key authentication in the initiator side
5711 in the server. Affected file silcd/protocol.c.
5713 * Removed the [RedirectClient] config section from the server
5714 configuration. Is not needed and I don't want to implement it.
5716 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Cleaned up the CMODE command in the server. It now works
5719 correctly and supports all the modes defined in the protocol.
5720 Affected file is silcd/command.c.
5722 * Added `hmac_name' field to the SilcChannelEntry in the server
5723 to hold the default HMAC of the channel. It can be set when
5724 creating the channel (with JOIN command). Affected files
5727 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5728 type to indicate the change of the current cipher and hmac
5729 on the channel. Client can safely ignore the <cipher> argument
5730 (if it chooses to do so) since the CHANNEL_KEY packet will
5731 force the channel key change anyway. The <hmac> argument is
5732 important since the client is responsible of setting the new
5733 HMAC and the hmac key into use.
5735 * Fixed the CMODE command in the client library as well.
5737 * Tested CMODE command in router environment successfully.
5739 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Show the version of the remote client (or server) when connecting
5742 to the server. It is logged to the log file. Affected file
5743 is silcd/protocol.c.
5745 * Fixed the KILLED notify handling in the client library. The
5746 client must be removed from all channels when receiving the
5749 Also, do not remove the client entry when giving the KILL
5750 command but when the KILLED notify is received.
5752 * Removed silc_idlist_find_client_by_nickname from the server.
5753 Not needed anymore. Affected files silcd/idlist.[ch].
5755 * Implemented the CHANNEL_CHANGE notify type handling to the
5756 server. Affected file silcd/server.c.
5760 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Added silc_server_send_notify_invite to send the INVITE
5763 notify between routers.
5765 * Implemented the INVITE command correctly to the server.
5767 * Implemented the INVITE notify type handling in the server.
5769 * Implemented the INVITE command to the client library and on the
5772 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added function silc_server_get_client_resolve to find the
5775 client entry by ID from all ID lists and then resolve it
5776 (using WHOIS) if it cannot be found. Affected file is
5779 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Implemented the BAN command to the client library.
5783 * The JOIN command in the server now checks the invite list
5786 * Changed the silc_command_reply_payload_encode_va and the
5787 silc_command_payload_encode_va to support that if argument is
5788 NULL it ignores and checks the next argument. Affected file
5789 lib/silccore/silccommand.c.
5791 * Added silc_server_send_notify_ban to send the BAN notify
5792 type between routers.
5794 * Chaned the silc_notify_payload_encode to support that if
5795 argument is NULL it ignores and checks the next argument.
5796 Affected file lib/silccore/silcnotify.c.
5798 * Tested ban lists in router environment successfully.
5800 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Implemented BAN command to the server, in silcd/command.[ch].
5804 * Removed the BAN and INVITE_LIST modes from the CMODE command
5807 * Added function silc_string_match to regex match two strings.
5808 Affected files lib/silcutil/silcutil.[ch].
5810 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Redefined parts of the SilcChannelEntry in the server to support
5813 the new ban and invite lists.
5815 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Redefined the INVITE command. The same command can be used to
5818 invite individuals to the channel but also to manage the invite
5819 list of the channel (to add to and remove from the invite list).
5820 Updated the protocol specs.
5822 * Added new command SILC_COMMAND_BAN that can be used to manage
5823 the ban list of the channel. Updated the protocol specs.
5825 * Removed the channel modes: the SILC_CMODE_BAN and the
5826 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5827 in the CMODE command. The equivalent features are now available
5828 using INVITE and BAN commands. Updated the protocol specs.
5830 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5831 in the network about change in the current ban list. The notify
5832 type is not used by the client.
5834 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5835 support the invite lists.
5837 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Added new function silc_string_regexify that converts string
5840 including wildcard characters into regex string that can
5841 be used by the GNU regex library. Added into the file
5842 lib/silcutil/silcutil.[ch].
5844 Added silc_string_regex_combine to combine to regex strings
5845 into one so that they can be used as one regex string by
5846 the GNU regex library. Added into the file
5847 lib/silcutil/silcutil.[ch].
5849 Added silc_string_regex_match to match two strings. It returns
5850 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5852 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Imported GNU regex to the soruce tree into lib/contrib.
5855 Fixed some compiler warning from the regex.c.
5857 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Fixed MOTD command in the server to work in router environment.
5861 * Fixed the MOTD command in the client library to support
5862 the server argument in the command.
5864 * Added `nickname_len' argument to the silc_idlist_add_client
5865 in the server, as the `nickname' argument may be binary data
5868 * Added silc_idlist_get_channels to return all channels from
5871 * Implemented LIST command to the server. Affected file is
5874 * Implemented the LIST command to the client library and on the
5877 * Added [<user count>] argument to the LIST command reply.
5878 With private channels the user count is not shown.
5880 * Updated TODO and README.
5882 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * The client entry's data.registered must be TRUE even with
5885 global client entry on global client list. The data.registered
5886 is used to check whether the client is anymore in the network,
5887 for example with WHOWAS command so it must be valid.
5889 * Fixed the WHOWAS command in the server. It now actually works
5890 in router environment. Added function into silcd/command_reply.c
5891 silc_server_command_reply_whowas_save.
5893 * Added silc_idlist_purge function to the silcd/idlist.c
5894 to periodically purge the ID Cache.
5896 * Fixed INFO command in the server. It works now in router
5897 environment. Added <server name> argument to the INFO command
5898 reply. Updated the protocol specs.
5900 * Fixed minor bug in silc_idcache_purge to not purge if the
5901 expire value is zero.
5903 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5904 they were buggy because of the WHOWAS information.
5906 * Fixed local command MSG to handle the async resolving of
5907 the remote client properly. It used to fail the first MSG.
5908 Affected file silc/local_command.c.
5910 * Added `data_len' field to SilcIDCache context.
5912 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Update TODO. Todo in commands in the server.
5916 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5919 used by routers as broadcast packet to inform other routers
5920 about the changed user mode.
5922 Implemented the notify handling in the server. Affected file is
5923 silcd/packet_receive.c. Added the function
5924 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5926 * Added new generic Channel Payload and deprecated the New Channel
5927 Payload. The New Channel Payload is now the generic Channel
5930 * Added new argument `mode' to the silc_server_send_new_channel
5931 as it is required in the Channel Payload now.
5933 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5934 and created a new and real SilChannelPayload to represent the
5935 new generic Channel Payload. Implemented the encode/decode
5936 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5938 * Added silc_server_get_client_channel_list to return the list
5939 of channels the client has joined for WHOIS command reply.
5940 Affected file silcd/server.[ch].
5942 * Implemented the channel list sending in the WHOIS command reply
5943 in server and in the client.
5945 Implemented the channel list displaying on the user interface
5946 as well. Affected file silc/client_ops.c.
5948 * Added silc_channel_payload_parse_list to parse list of Channel
5949 Payloads. It returns SilcDList list of SilcChannelPayloads.
5950 Client for example can use this function to parse the list of
5951 channels it receives in the WHOIS command reply. The caller
5952 must free the list by calling silc_channel_payload_list_free.
5953 Affected files lib/silccore/silcchannel.[ch].
5955 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Added one new argument <user mode> to the WHOIS command reply
5958 to return the mode of the user in SILC. Updated the protocol
5961 Implemented it to the server and client.
5963 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Fixed the mode printing on the user interface on joining.
5966 Affected file silc/client_ops.c.
5968 * Implemented the UMODE command and user modes in general to the
5969 client library and to the user interface.
5971 * Implemented the UMODE command to the server.
5973 * The server now sends UNKNOWN_COMMAND error status if client sends
5974 unknown command. Affected file silcd/command.c.
5976 * All server commands now handle the command identifier the right
5977 way when sending the command reply to the client. The client can
5978 use to identify the command replies with the identifier.
5980 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Added silc_server_get_client_route to resolve the route to
5983 the client indicated by the client ID. Affected file is
5986 * Added silc_server_relay_packet as general function to relay
5987 packet to arbitrary destination. This deprecates functions
5988 like _send_private_message_key, _relay_notify etc. Affected
5989 file is silcd/packet_send.[ch].
5991 Removed silc_server_send_key_agreement,
5992 silc_server_send_private_message_key and
5993 silc_server_packet_relay_notify functions from the file
5994 silcd/packet_send.[ch].
5998 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5999 server. Affected file silcd/packet_receive.[ch].
6001 * Implemented the KILL command to the client. Implemented the
6002 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6003 Affected files lib/silcclient/command[_reply].c and
6004 lib/silcclient/client_notify.c. Implemented the KILL notify
6005 printing in the user inteface.
6007 * Fixed a lot silc_parse_nick memory leaks from the client
6008 library in the file lib/silcclient/command.c.
6010 * Changed the silc_server_send_notify_on_channels's `sender'
6011 argument from SilcSocketConnection to SilcClientEntry to
6012 check the sender as entry and not as connection object and not
6013 to send to the client provided as argument. The affected file
6014 is silcd/packet_send.[ch].
6016 * The notify packets that are destined directly to the client used
6017 to not to be processed by the server. Now changed that and the
6018 server processes all notify packets. After relaying the packet
6019 to the client the notify packet is processed in the server.
6021 * The silc_server_free_client_data now checks whether there is
6022 pending outgoing traffic for the client and purges the data to
6023 the network before removing the client entry.
6025 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6028 an client is killed from the SILC Network. Updated the protocol
6031 Added new function silc_server_send_notify_killed to the
6032 silcd/packet_send.[ch].
6034 * Added function silc_server_packet_relay_notify to relay notify
6035 packets that are destined directly to a client. In this case
6036 the server does not process the notify packets but merely relays
6037 it to the client. Affected file silcd/packet_send.[ch].
6039 Added also silc_server_packet_process_relay_notify to check
6040 whereto relay the notify. Affected file is
6041 silcd/packet_receive.[ch].
6043 * Implemented the KILL command to the server.
6047 * Added the backup schema desgined last fall to the protocol
6048 specs for everyone to see. The specification is in the
6049 *-spec-xx.txt draft and the packet type definitions for the
6050 backup routers is in *-pp-xx.txt draft. Thusly, added also
6051 new packet type SILC_PACKET_CELL_ROUTERS.
6053 * A big security problem in the implementation discovered. The
6054 signoff of an client did not cause new channel key generation
6055 which it of course should've done. The channel keys must be
6056 always re-generated when client leaves (or signoffs) the channel.
6057 The silc_server_remove_from_channels funtion now handles
6058 the channel key re-generation.
6060 * Added `sender' argument to the silc_server_send_notify_on_channels
6061 to not to send the client provided as argument. Affected file
6062 silcd/packet_send.[ch].
6064 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Implemented OPER and SILCOPER commands into the server and
6069 * Added silc_auth_verify and silc_auth_verify_data to verify
6070 the authentication directly from the authentication payload.
6071 It supports verifying both passphrase and public key based
6072 authentication. Affected file lib/silccore/silcauth.[ch].
6074 * Added `hash' field to the SilcIDListData structure. It is the
6075 hash negotiated in the SKE protocol. Affected file is
6078 * Slight redesigning of the SilcAuthPayload handling routines.
6079 Do not send SilcPKCS but SilcPublicKey as argument.
6081 * Implemented the public key authentication support to the
6082 serverconfig. The public key is loaded from the provided path
6083 and saved as authentication data to void * pointer. Thus,
6084 changed the unsigned char *auth_data to void *auth_data;
6086 * Fixed SHUTDOWN command to send the reply before the server
6087 is shutdown. :) Affected file silcd/command.c.
6089 * Fixed fatal bug in CONNECT command. The hostname was invalid
6090 memory and server crashed. Affected file silcd/command.c.
6092 * Fixed fatal bug in CLOSE command. The server_entry became
6093 invalid but was referenced later in the command. Affected file
6096 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Fixed fatal bug in failure packet handling. Server ignored
6099 the failure and thus crashed when it came.
6103 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6106 that the command may be executed only once in (about) 2 seconds.
6107 The old SILC_CF_LAG flag is same but allows command bursts up
6108 to five before limiting.
6110 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6111 server code. Various commands now includes the CF_LAG_STRICT
6112 flag to disallow any kind of miss-use of the command.
6114 * Fixed the silc_buffer_unformat to not to allocate any data
6115 if the length of the data is zero. It used to allocate the
6116 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6118 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Changed the format of AdminConnection configuration section
6121 in the server. Added username of the admin to the format.
6122 Affected files silcd/serverconfig.[ch].
6124 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6125 to return admin configuration data by host, username and/or
6128 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Implemented WHOWAS command to the server. Added the functions:
6132 silc_server_command_whowas_parse,
6133 silc_server_command_whowas_send_reply,
6134 silc_server_command_whowas_from_client and
6135 silc_server_command_whowas_from_server
6137 * Added <Client ID> argument to the WHOWAS command reply. Updated
6138 the protocol specs accordingly.
6140 * Implemented WHOWAS command and command_reply to the client
6143 Implemented the WHOWAS printing on the user interface.
6145 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added new argument to the WHOWAS command reply, the real name.
6148 It is an optional argument. Updated the protocol specs.
6150 * Added SilcIDCacheDestructor callback that is registered when
6151 the SilcIDCache is allocated. The callback is called when
6152 an cache entry in the ID Cache expires, or is purged from the
6153 cache. Added into lib/silccore/idcache.[ch].
6155 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6156 to destruct the client entries when the cache entry expires.
6157 Other ID Cache's in server and in the client library ignores
6160 * If the ID Cache entry's `expire' field is zero then the entry
6161 never expires. Added boolean `expire' argument to the
6162 silc_idcache_add function in the lib/silccore/idcache.[ch].
6163 If it is TRUE the default expiry value is used.
6165 * Added silc_server_free_client_data_timeout that is registered
6166 when client disconnects. By default for 5 minutes we preserve
6167 the client entry for history - for WHOWAS command.
6169 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Added support to the server to enforce that commands are not
6172 executed more than once in 2 seconds. If server receives
6173 commands from client more frequently, timeout is registered
6174 to process the commands. Affected file silcd/command.c.
6175 Added new function silc_server_command_process_timeout.
6177 * Changed NICK_NOTIFY handling in client library to check that
6178 if the client's nickname was changed, so there is no need to
6179 resolve anything from the server.
6181 * Removed error printing from the WHOIS and IDENTIFY commands.
6182 If error occurs then it is ignored silently in the client library.
6183 The application, however, may map the received error to
6184 human readable error string. The application currently maps
6185 the NO_SUCH_NICKNAME error to string.
6187 * Made the command status message public to the application. Moved
6188 them from lib/silcclient/command_reply.c to
6189 lib/silcclient/command_reply.h. The application can map the
6190 received command status to the string with the
6191 silc_client_command_status_message function.
6193 * Added check to the server to check that client's ID is same
6194 as the Source ID in the packet the client sent. They must
6197 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added dist-bzip hook to the Makefile.am to make bzip2
6200 compressed distributions.
6202 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Server now enforces the maximum length for the nickname and
6205 the channel as protocol specification dictates. 128 bytes for
6206 nickname and 256 bytes for channel name.
6208 * Moved the WHOIS printing to the application. The client libary
6209 does not print out the WHOIS information anymore, the application
6210 must do it. Renamed silc_client_command_reply_whois_print to
6211 the silc_client_command_reply_whois_save.
6213 The client's idle time is also sent to the application now, and
6214 the idle is shown on screen.
6216 * Added silc_client_command_reply_identify_save to save the
6217 received IDENTIFY entries.
6219 * Do not check for channel private keys in message sending and
6220 reception if the channel does not have the PRIVKEY mode set.
6221 Affected file lib/silclient/client_channel.c.
6223 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6226 just surfaced after chaning the JOIN procedure.
6228 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Added silc_client_get_clients_by_list to get client entries
6231 from Client ID list, that is returned for example by JOIN
6232 and USERS command replies. The application should use this
6233 function for example when JOIN command reply is received to
6234 resolve the clients already on the channel (library does not
6235 do that anymore as USERS command reply is not used in the JOIN
6236 procedure anymore). Affected files lib/silcclient/silcapi.h and
6237 lib/silcclient/idlist.c.
6239 * JOIN command reply and USERS command reply returns now SilcBuffer
6240 pointers instead of unsigned char pointers when returning
6241 the client list and mode list.
6243 * Added <Client ID> argument to the JOIN command reply, mainly
6244 for the server to identify for which client the command was
6245 originally sent. Updated protocol specs accordingly.
6247 * Added SilcDlist private_key pointer to the SilcChannelEntry
6248 in the client to support the channel private keys. Affected
6249 file is lib/silcclient/idlist.h.
6251 * Added SilcChannelPrivateKey argument to the function
6252 silc_client_send_channel_message so that application can choose
6253 to use specific private ke if it wants to. If it is not provided,
6254 the normal channel key is used, unless private keys are set.
6255 In this case the first (key that was added first) is used
6256 as the encryption key.
6258 * Implemented the support for channel private key handling.
6259 Implemented the following functions:
6261 silc_client_add_channel_private_key,
6262 silc_client_del_channel_private_keys,
6263 silc_client_del_channel_private_key,
6264 silc_client_list_channel_private_keys and
6265 silc_client_free_channel_private_keys
6267 Affected file lib/silcclient/client_channel.c.
6269 * Added the support for the private keys in the channel message
6270 sending and encryption and in the message reception and
6271 decryption. Affected funtions are
6272 silc_client_send_channel_message and silc_client_channel_message.
6274 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6276 * Added SKE's key verify callback to the client library's
6277 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6279 * Removed the statement that server (or router) must send USERS
6280 command reply when joining to the channel so that the client
6281 knows who are on the channel. Instead, the client list and
6282 client's mode list is now sent in the JOIN command reply to the
6283 client who joined channel. This is better solution.
6285 * Added function silc_server_get_users_on_channel and function
6286 silc_server_save_users_on_channel to the silcd/server.[ch].
6288 * Removed function silc_server_command_send_users from the
6291 * Do not show topic on the client library anymore. The topic is
6292 sent in the command reply notify to the application and the
6293 application must show the topic now.
6295 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Added client searching by nickname hash into the IDENTIFY and
6298 WHOIS commands in the server as they were clearly missing from
6299 them. Affected file is silcd/command.c.
6301 * Fixed a bug in private message receiving in the client library.
6302 The remote ID was freed and it wasn't supposed, now it is
6305 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Minor fix to the channel payload; allocate the data area, as it
6308 needs to be of specific length.
6310 * If the key agreement port is zero then the operating
6311 system will define the bound port. Affected files are
6312 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6314 * Added new function silc_channel_payload_decrypt into the file
6315 lib/silccore/silcchannel.[ch].
6317 * Moved the channel message etc, check from silc_packet_decrypt
6318 to applications. The library calls now a generic
6319 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6320 when the packet is either normal or special. This was done to
6321 allow more wide range of checking that was not allowed when
6322 the code was in library. Now applications can do virtually any
6323 checks to the packet and return to the library the decision how
6324 the packet should be processed. Affected files are
6325 lib/silccore/silcpacket.[ch].
6327 Added silc_server_packet_decrypt_check to the server and
6328 silc_client_packet_decrypt_check to the client library.
6330 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6331 to send with specified source and destination information.
6333 * Channel message delivery between routers was broken after the
6334 channel key distribution was fixed earlier. The channel key
6335 was used be to distributed to other routers as well which is not
6336 allowed by the protocol. Now this is fixed and channel keys
6337 really are cell specific and the channel message delivery between
6338 routers comply with the protocol specification.
6340 * Fixed various commands in server to check also the global list
6341 for the channel entry and not just the local list. The affected
6342 file silcd/command.c.
6344 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Added assert()s to buffer formatting and unformatting routines
6347 to assert (if --enable-debug) when error occurs. Affected
6348 file: lib/silcutil/silcbuffmt.c.
6350 * Changed to auto-reconnect to check whether the remote host is
6351 router and register the re-connect timeout if it is. It used
6352 to check that whether we are normal server, but router must do
6353 auto-reconnect with another router as well. Affected file
6356 * Removed the [<key len>] option from CMODE command as the cipher
6357 name decides the key length, nowadays. See the defined ciphers
6358 from the protocol specification.
6360 * Added [<hmac>] option to the CMODE command to define the HMAC
6361 for the channel. Added SILC_CMODE_HMAC channel mode.
6363 * Added [<hmac>] option for the JOIN command so that user can
6364 select which HMAC is used to compute the MACs of the channel
6367 * Added Hmac field to the Channel Message Payload. The integrity
6368 of plaintext channel messages are now protected by computing
6369 MAC of the message and attaching the MAC to the payload. The
6370 MAC is encrypted. Now, it is clear that this causes some
6371 overhead to the size of the packet but rationale for this is that
6372 now the receiver can verify whether the channel message decrypted
6373 correctly and also when private keys are set for the channel the
6374 receiver can decrypt the packet with several keys and check from
6375 the MAC which key decrypted the message correctly.
6377 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6378 lib/silccrypt/silccipher.[ch].
6380 * Added silc_hash_len to return the digest length into the
6381 lib/silcrypt/silchash.[ch].
6383 * Rewrote parts of Silc Channel Payload interface in the
6384 lib/silccore/silcchannel.[ch]. The encode function now also
6385 encrypts the packet and parse function decrypts it.
6387 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Fixed a minor formatting bug in the SKE's key material processing.
6390 It actually might have processed the keys wrong way resulting
6393 * Redefined the mandatory HMAC algorithms and added new algorithms.
6394 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6395 and hmac-md5 truncated to 96 bits. The mandatory is now
6396 hmac-sha1-96. Rest are optional (including the one that used
6397 to be mandatory). Rationale for this is that the truncated HMAC
6398 length is sufficient from security point of view and can actually
6399 make the attack against the HMAC harder. Also, the truncated
6400 HMAC causes less overhead to the packets. See the RFC2104 for
6403 * Added new [hmac] configuration section. The SKE used to use
6404 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6405 is of course wrong. The official names that must be proposed in
6406 the SKE are the ones defined in the protocol specification
6407 (hmac-sha1-96 for example). The user can configure any hmac
6408 using any hash function configured in the [hash] section. At
6409 least, the mandatory must be configured.
6411 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6413 * Added HMAC list to the SKE proposal list. It has now both
6414 hash algorithm list and HMAC list. This makes the protocol
6415 incompatible with previous versions. The SKE now seems to work
6416 the way it is supposed to work, for the first time actually.
6418 * Defined plain Hash algorithms to the protocol specification.
6421 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Implemented support for key agreement packets into the server.
6424 Added functions silc_server_key_agreement and
6425 silc_server_send_key_agreement. Other than these functions,
6426 server has nothing to do with this packet.
6428 * Added support for private message key packets into the server.
6429 Added functions silc_server_private_message_key and
6430 silc_server_send_private_message_key.
6434 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6435 called in the protocol's final callback instead in the END
6436 protocol state. This makes a little more sense and in the same
6437 time in client we can use the same protocol routines for normal
6438 key exchange and to key agreement packet handling as well.
6440 * Added to both client's and server's KE protocol context the
6441 SilcSKEKeyMaterial pointer to save the key material. We will
6442 bring the key material to the protocol's final callback by doing
6443 this. The final callback must free the key material.
6445 * Added SKE's packet_send callback into client's KE protocol
6446 context so that the caller can choose what packet sending function
6447 is used. This way we can use different packet sending when
6448 doing normal SKE when doing key agreement packet handling (in
6449 the key agreement packet handling we do not want to encrypt
6452 * Implemented the responder side of the key agreement routines
6453 in the client. The client can now bind to specified port and
6454 accept incoming key negotiation. The key material is passed
6455 to the application after the protocol is over.
6457 * Implemented the processing of incoming Key Agreement packet
6458 in the client. Added function silc_client_key_agreement to
6461 * Implemented the intiator side of the key agreement routines
6462 in the client. The client can now initiate key agreement with
6463 another remote client. The key material is passed to the
6464 application after the protocol is over.
6466 * Created client_keyagr.c to include all the key agreement
6469 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6470 SILC_TASK_CALLBACK except that it is not static.
6472 * Created client_notify.c and moved the Notify packet handling
6473 from the client.[ch] into that file.
6475 * Created client_prvmsg.c and moved all private message and
6476 private message key routines from the client.[ch] into that file.
6478 * Create client_channel.c and moved all channel message and
6479 channel private key routines from the client.[ch] into that file.
6481 * Changed silc_client_get_client_by_id_resolve to resolve with
6482 WHOIS command instead of IDENTIFY command, in the file
6483 lib/silclient/idlist.c.
6485 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Implemented the SKE's responder side to the Client library.
6489 * When FAILURE is received to the protocol do not trust it
6490 blindly. Register a timeout to wait whether the remote closes
6491 the connection as it should do it, only after that process the
6492 actual failure. This was changed to both client and server.
6494 * Added client_internal.h to include some of the structures
6495 there instead of client.h in lib/silcclient/.
6497 * Added function silc_task_unregister_by_callback to unregister
6498 timeouts by the callback function.
6500 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Some "Incomplete WHOIS info" errors has been appearing on the
6503 log files. Took away the entry->userinfo check from WHOIS
6504 reply sending. The entry->userinfo is now " " if client did not
6505 provide one. I thought this was fixed earlier but something
6506 is wrong still. Let's see if the error still appears.
6508 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Fixed a minor bug in the login when the channel key is
6511 re-generated in the server. It used to generate the key in
6512 wrong order and thus caused problems in the channel traffic.
6514 * Fixed a minor bug in channel key distsribution after
6515 KICK command. The key was not sent to the router even though
6518 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Added silc_ske_process_key_material_data as generic routine
6521 to process any key material as the SILC protocol dictates. The
6522 function is used by the actual SKE library but can be used by
6523 applications as well. This relates to the private message keys
6524 and the channel private keys since they must be processed the
6525 same way the normal SILC session keys. The protocol dictates
6526 this. Affected files: lib/silcske/silcske.[ch].
6528 Added also silc_ske_free_key_material to free the
6529 SilcSKEKeyMaterial structure.
6531 * Defined silc_cipher_set_key function to set the key for
6532 cipher without using the object's method function. The affected
6533 files: lib/silccrypt/silccipher.[ch].
6535 * Implemented silc silc_client_add_private_message_key,
6536 silc_client_add_private_message_key_ske,
6537 silc_client_del_private_message_key,
6538 silc_client_list_private_message_keys and
6539 silc_client_free_private_message_keys functions in the
6542 Added functions silc_client_send_private_message_key to send
6543 the Private Message Key payload and silc_client_private_message_key
6544 to handle incoming Private Message Key payload.
6546 * Added Cipher field to the Private Message Key payload to set
6547 the cipher to be used. If ignored, the default cipher defined
6548 in the SILC protocol (aes-256-cbc) is used.
6550 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Removed lib/silcclient/ops.h file.
6554 Redefined parts of the SILC Client Library API. Created new
6555 file silcapi.h that deprecates the ops.h file and defines the
6556 published Client Library API. Defined also private message key
6557 API and channel private key API into the file.
6559 This is the file that the application must include from the
6560 SILC Client Library. Other files need not be included by
6561 the application anymore.
6563 * Added new key_agreement client operation callback and also
6564 defined the Key Agreement library API for the application.
6566 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6569 is used by clients to request key negotiation between another
6570 client in the SILC network. If the negotiation is started it
6571 is performed using the SKE protocol. The result of the
6572 negotiation, the secret key material, can be used for example
6573 as private message key.
6575 Implemented the Key Agreement payload into the files
6576 lib/silccore/silauth.[ch].
6578 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Redefined ciphers for the SILC protocol. Added some new ciphers
6581 and defined the key lengths for the algorithms. Changed the
6582 code accordingly. The default key length is now 256 bits.
6584 * Fixed SKE key distribution function silc_ske_process_key_material
6585 when the key length is more than 128 bits. The default key
6586 length in SILC is now 256 bits.
6588 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6589 to indicate unsupported algorithm.
6591 * Renamed rijndael.c to aes.c and all functions as well.
6593 * Fixed a long standing channel key setting bug in client library.
6594 Weird that it has never surfaced before.
6596 * Fixed bug in channel deletion. If the entire channel is removed
6597 then it must also delete the references of the channel entry
6598 from the client's channel list as the client's channel entry and
6599 the channel's client entry share same memory.
6601 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Implemented CONNECT and SHUTDOWN commands in the client.
6605 * Implemented CLOSE command to the client.
6607 * Added the function silc_idlist_find_server_by_name into the
6608 files silcd/idlist.[ch].
6610 Added the function silc_idlist_find_server_by_conn into the
6611 files silcd/idlist.[ch].
6613 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * DIE command was renamed to SHUTDOWN. Updated the both code
6618 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6619 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6621 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6624 * Added function silc_server_create_connection function to create
6625 connection to remote router. My server implementation actually
6626 does not allow router to connect to normal server (it expects
6627 that normal server always initiates the connection to the router)
6628 so the CONNECT command is only good for connecting to another
6631 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6634 or some other client was kicked from the channel.
6636 Implemented the handling of the notify type to both client
6639 Implemented silc_server_send_notify_kicked to send the KICKED
6640 notify. It is used to send it to the server's primary router.
6642 * Implemented the KICK command into server and client.
6644 * Added `query' argument to the silc_idlist_get_client function
6645 to indicate whether to query the client from server or not if
6648 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6649 to indicate that the client is not channel founder.
6653 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Removed the rng context from SilcPacketContext structure and
6656 changed that the packet routine uses the Global RNG API.
6658 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6660 * Added support for quit message that client can "leave" on the
6661 channel when it quits the SILC. It is ditributed inside the
6662 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6664 Added silc_server_free_client_data that will take the
6665 signoff message as argument.
6667 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6669 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Updated parts of the protocol specification to keep it up
6674 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6677 payloads in one packet.
6679 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6680 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6681 use now the new List flag.
6683 * Also deprecated the following packet types: REPLACE_ID,
6684 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6686 * Added list support for Notify packet in server.
6688 * Added silc_server_send_notify_channel_change to send the
6689 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6690 the silc_server_send_replace_id.
6692 * Added silc_server_send_notify_nick_change to send the
6693 NICK_CHANGE notify type. Deprecates the function
6694 silc_server_send_replace_id.
6696 * Added silc_server_send_notify_join to send the JOIN notify type.
6697 Deprecates the function silc_server_send_new_channel_user.
6699 * Added silc_server_send_notify_leave to send LEAVE notify type.
6700 Deprecates the function silc_server_send_remove_channel_user.
6702 * Added silc_server_send_notify_cmode and
6703 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6704 types. Deprecates the silc_server_send_set_mode function.
6706 * Added SERVER_SIGNOFF notify type to indicate that server has
6707 quit. This means that all clients on the channel from that
6708 server will drop. This can be also used when netsplit happens.
6710 Deprecated REMOVE_ID packet type since it is not needed anymore
6713 Added silc_server_send_notify_server_signoff to send the
6714 SERVER_SIGNOFF notify type. Deprecates the function
6715 silc_server_send_remove_id.
6717 Added also silc_server_send_notify_signoff to send the
6718 SIGNOFF notify type.
6720 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6721 SILC protocol from this day on. Changed the protocol
6722 specification as well.
6724 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6725 notify type. It is used between routers to notify about
6726 topic changes on a channel.
6728 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6731 * Partly updated the protocol specification to comply with the
6732 changes now made. It is still though a bit outdated.
6734 * The JOIN notify type now takes one extra argument <Channel ID>.
6735 The packet used to be destined to the channel but now the
6736 JOIN type may be sent as list thus it is impossible to
6737 destine it to any specific channel. By adding this argument
6738 it is again possible.
6740 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Added CREDITS file. The CHANGES and CREDITS file will appear
6743 in the distribution as well.
6745 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6748 types in the server's silcd/packet_receive.c.
6750 * Implemented CMODE and CUMODE to work in router environment.
6752 * Fixed minor encoding and decoding buglet from the
6753 lib/silccore/silcmode.c.
6755 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6758 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6760 * Changed all SilcConfigServer* and silc_config_server* to
6761 SilcServerConfig* and silc_server_config*, respectively.
6764 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6766 * Associated the ID (client or server ID) to the Authentication
6767 Payload to avoid any possibility of forging. Updated the
6768 protocol specification and the code accordingly.
6770 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * The RSA key length is now save to the RsaKey context in the
6773 key generation process in lib/silccrypt/rsa.c. The key length
6774 is now used to figure out the maximum size of the block allowed
6775 to be encrypted/signed.
6777 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6778 is equivalent to the silc_mp_mp2bin but does not allocate any
6781 * Changed silc_mp_mp2bin API to take length argument. If it is
6782 non-zero then the buffer is allocated that large. If zero, then
6783 the size is approximated using silc_mp_sizeinbase, which however
6786 * Created Global RNG API which is global RNG that application can
6787 initialize. After initializing, any routine anywhere in the
6788 code (including library) can use RNG without allocating a new
6789 RNG object. This was done to allow this sort of use of the
6790 RNG in code that has no chance to allocate RNG object. All
6791 applications currently allocate this and many routines in the
6792 library use this. Affected file lib/silccrypt/silcrng.[ch].
6794 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6795 it to use the Global RNG API.
6797 * Defined Authentication Payload into protocol specification that
6798 is used during SILC session to authenticate entities. It is
6799 used for example by client to authenticate itself to the server
6800 to obtain server operator privileges.
6802 Implemented this payload into the lib/silccore/silcauth.[ch].
6803 Implemented also routines for public key based authentication
6804 as the new protocol specification dictates.
6806 Moved definitions of different authentication methods from
6807 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6809 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6810 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6811 silc_pkcs_verify_with_hash functions into the file
6812 lib/silccrypt/silcpkcs.[ch].
6814 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * The client entry's userinfo pointer must be always valid.
6817 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6818 will fail since it requires the userinfo. Now, the userinfo
6819 is allocated as "" if actual userinfo does not exist. Actually,
6820 it must exist and it is totally Ok to drop client connections
6821 that does not announce the userinfo. However, we will make
6822 this workaround for now.
6824 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6825 to return the remote port by socket.
6827 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6830 SILC_SERVER_PENDING_EXEC and added an new macro
6831 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6832 data or when error occurs while processing the pending command.
6834 Added new argument `destructor' into silc_server_command_pending
6835 and to the SilcServerCommandPending object. This destructor is
6836 now called after calling the pending callback or if error occurs
6837 immediately. If error occurs the actual pending callback won't
6838 be called at all - only the destructor. The destructor may be
6839 NULL if destructor is not needed.
6841 All this applies for client library code as well. Similar
6842 changes were made there as well for the pending commands.
6844 In the client, the application must now allocate the
6845 SilcClientCommandContext with the silc_client_command_alloc
6848 * Added reference counter to the SilcServerCommandContext. Added
6849 function silc_server_command_alloc and silc_server_command_dup
6852 Same type of functions added to the client library for the same
6855 * Removed the cmd_ident from IDListData away since it is now
6856 global for all connections. It is the command identifier used
6857 in command sending and with pending commands. The affected file
6860 * Added reference counter to the SilcSocketConnection objecet to
6861 indicate the usage count of the object. The object won't be
6862 freed untill the reference counter hits zero. Currently only
6863 server uses this, and client ignores it. The client must be
6864 set to use this too later. The affected files are
6865 lib/silccore/silcsockconn.[ch]. Added also the function
6866 silc_socket_dup to increase the reference counter.
6868 This was mainly added because it is possible that the socket
6869 is removed underneath of pending command or other async
6870 operation. Now it won't be free'd and proper DISCONNECTING
6871 flags, etc. can be set to avoid sending data to connection that
6872 is not valid anymore.
6874 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6875 the connection. After that it sets SILC_SET_DISCONNECTED.
6876 It is, however, possible that the socket data is not still freed.
6877 The silc_server_packet_process now checks that data is not
6878 read or written to connection that is DISCONNECTED. The socket
6879 get's freed when the reference counter hits zero.
6881 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Changed the client operation API: channel_message operation's
6884 `sender' is now the client entry of the sender, not the nickname
6885 and the `channel' is the channel entry, not the channel name.
6887 In the private_message operation the `sender' is now also the
6888 client entry of the sender not the nickname.
6890 Affected file is lib/silcclient/ops.h and all applications
6891 using the client operations.
6893 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Moved the calling of ops->connect() from connect_to_server_final
6896 into receive_new_id functin since that is the point when the
6897 client is actually allowed to send traffic to network. The
6898 affected file is lib/silcclient/client.c.
6900 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6903 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6904 (if needs broadcasting) instead of broadcasting the packets one
6905 by one which would make a burst in the network traffic.
6907 * Added `broadcast' argument to the functions in silcd/server.[ch]
6908 silc_server_create_new_channel[_with_id] to indicate whether
6909 to send New Channel packet to primary router.
6911 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added new function into the silcd/server.[ch] files:
6914 silc_server_create_new_channel_with_id to create new channel with
6915 already existing Channel ID.
6917 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6918 lib/silccore/silcpacket.h. This packet is used t send list of
6919 Set Mode payloads inside one packet. Server uses this to set
6920 the modes for the channels and clients on those channels, that it
6921 announced to the router when it connected to it. The protocol
6922 specification has been updated accordingly.
6924 * The silc_server_new_channel did not handle the packet coming
6925 from normal server as it normally does not send that. However,
6926 when it announces its channels it does send it. Implemented
6927 the support for that.
6929 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6930 into the file lib/silccore/id.h.
6932 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Fixed memory leaks in the functions silc_idlist_del_client,
6935 silc_idlist_del_channel and silc_idlist_del_server in the file
6936 silcd/idlist.c. All of those leaked like a sieve.
6938 * Fixed some small memory leaks in the client's function
6939 silc_client_notify_by_server.
6941 * Added functions into silcd/server.c: silc_server_announce_clients,
6942 silc_server_announce_channels and silc_server_announce_server.
6943 These functions are used by normal and router server to announce
6944 to its primary router about clients, channels and servers (when
6945 router) that we own. This is done after we've connected to the
6948 These functions effectively implements the following packet types:
6949 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6950 and SILC_PACKET_NEW_ID_LIST.
6952 * Added new functions into the silcd/packet_receive.[ch]:
6953 silc_server_new_id_list, silc_server_new_channel_list and
6954 silc_server_new_channel_user_list to handle the incoming
6955 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6957 * Added support of changing Channel ID in the function
6958 silc_server_replace_id. If the server that announces a channel
6959 to the router already exists in the router (with same name but
6960 with different Channel ID), router is responsible to send
6961 Replace ID packet to the server and force the server to change
6962 the Channel ID to the one router has.
6964 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6965 client that the Channel ID has been changed by the router. The
6966 normal server sends this to the client. Client must start using
6967 the new Channel ID as the channel's ID.
6969 Implemented handling of this new type into lib/silcclient/client.c
6970 into the function silc_client_notify_by_server.
6972 * Added new function silc_idlist_replace_channel_id into the files
6973 silcd/idlist.[ch] to replace the Channel ID.
6975 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Call silc_server_command_identify_check always when processing
6978 the IDENTIFY command in silcd/command.c
6980 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6982 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6983 send keepalive packets. The packet can be sent by clients,
6984 servers and routers.
6986 Added function silc_socket_set_heartbeat into the file
6987 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6988 If not set, the heartbeat is not performed. The actual
6989 heartbeat is implemented in the low level socket connection
6990 library. However, application is responsible of actually
6993 Added silc_server_send_heartbeat to send the actual heartbeat
6994 packet into silcd/packet_send.[ch]. Server now performs
6995 keepalive with all connections.
6997 * Added silc_task_get_first function into lib/silcutil/silctask.c
6998 to return the timeout task with shortest timeout. There was a bug
6999 in task unregistration that caused problems. TODO has been
7000 updated to include that task system must be rewritten.
7002 * The client library will now resolve the client information when
7003 receiving JOIN notify from server for client that we know but
7004 have incomplete information.
7006 * Rewrote parts of silc_server_remove_from_channels and
7007 silc_server_remove_from_one_channel as they did not remove the
7008 channel in some circumstances even though they should've.
7010 * Encryption problem encountered in server:
7012 The LEAVE command used to send the Channel Key packet to the
7013 router immediately after generating it. However, the code
7014 had earlier sent Remove Channel user packet but not immediately,
7015 ie. it was put to queue. The order of packets in the router
7016 was that Channel Key packet was first and Remove Channel User
7017 packet was second, even though they were encrypted in the
7018 reverse order. For this reason, MAC check failed. Now, this
7019 is fixed by not sending the Channel Key packet immediately but
7020 putting it to queue. However, this is more fundamental problem:
7021 packets that are in queue should actually not be encrypted
7022 because packets that are sent immediately gets encrypted
7023 actually with wrong IV (and thus MAC check fails). So, packets
7024 that are in queue should be encrypted when they are sent to
7025 the wire and not when they put to the queue.
7027 However, the problem is that the current system has not been
7028 designed to work that way. Instead, the packet is encrypted
7029 as soon as possible and left to the queue. The queue is then
7030 just purged into wire. There won't be any fixes for this
7031 any time soon. So, the current semantic for packet sending
7034 o If you send packet to remote host and do not force the send
7035 (the packet will be in queue) then all subsequent packets to the
7036 same remote host must also be put to the queue. Only after the
7037 queue has been purged is it safe again to force the packet
7040 o If you send all packets immediately then it safe to send
7041 any of subsequent packets through the queue, however, after
7042 the first packet is put to queue then any subsequent packets
7043 must also be put to the queue.
7045 Follow these rules and everything works fine.
7047 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Added new function silc_server_remove_clients_by_server to
7050 remove all client entries from ID list when the server connection
7051 is lost. In this case it is also important to invalidate all
7052 client entires as they hold the invalid server entry. This
7053 fixes fatal bug when server has lost connection and will reconnect
7056 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Made some sanity checks to silc_server_daemonise like to check
7059 whether the requested user and group actually exists.
7061 * Added sanity check to SKE's silc_ske_responder_finish to check
7062 that the public and private key actually is valid.
7064 * Invalidate the client's nickname when receiving Replace ID
7065 packet and the Client ID is being replaced. This means that the
7066 server will query the nickname if someone needs it (client)
7069 * Sort the ID Cache in client library when the ID Cache data
7070 has changed (needs sorting).
7072 * Do not allow for SILC client to create several connections to
7073 several servers. The client does not support windows right now
7074 and generating multiple connections causes weird behaviour.
7076 Irssi-silc client does support windows and can handle several
7077 connections without problems, see: www.irssi.org and SILC plugin.
7079 * Fixed some places where client was added to the IDList. The
7080 rule of thumb is following (in order to get everything right):
7081 If the client is directly connected local client then the
7082 `connection' argument must be set and `router' argument must be
7083 NULL to silc_idlist_add_client function. If the client is not
7084 directly connected client then the `router' argument must
7085 bet set and the `connection' argument must be NULL to the
7086 silc_idlist_add_client function.
7088 * The funtion silc_server_packet_send_local_channel actually did
7089 not check whether the client was locally connected or not. It
7090 does that now. Fixed a bug related to LEAVE command.
7092 * Fixed Remove Channel User payload parsing bug in server's
7093 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7095 * The server's silc_server_save_channel_key now checks also the
7096 global ID list for the channel as it might not be in the local
7097 list. Fixed a bug related to LEAVE command.
7099 * Is this the end of the [<unknown>] buglet that has been lurking
7100 around for a long time? A little for loop fix in server's
7101 silc_server_command_whois_parse that is used by both IDENTIFY
7102 and WHOIS command. At least, this was a clear bug and a cause
7103 of one type of [<unknown>] buglet.
7105 * WHOIS and IDENTIFY commands call the function
7106 silc_server_command_[whois/identify]_check function even if
7107 we are not router server.
7109 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Added --with-gmp configuration option. If set the GMP
7112 is always compiled in the SILC source tree. If not set then
7113 it is checked whether the system has the GMP3 installed. If
7114 it has then the GMP won't be compiled (the system's headers
7115 and library is used), if it doesn't have it then the GMP is
7116 compiled in the SILC source tree.
7118 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Changed RSA private exponent generation to what PKCS #1
7121 suggests. We try to find the smallest possible d by doing
7122 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7123 not security fix but optimization.
7125 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Added new config entry [Identity] to fork the server and run
7128 it as specific user and group. A patch from Bostik.
7130 * Imported Dotconf configuration library into lib/dotconf.
7131 This will be used to create the SILC configuration files later.
7132 It will appear in the distsribution after this commit.
7134 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * A big code auditing weekend happening. Auditing code for
7137 obvious mistakes, bugs and errors. Also, removing any code
7140 Removed files for being obsolete:
7142 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7143 inline in the file lib/silcutil/silcbuffer.h)
7145 o lib/silcutil/silcbufutil.c (the header has inline versions)
7147 Changed code to fix possible error conditions:
7149 o The buffer formatting routines now check that the destination
7150 buffer really has enough space to add the data. This applies for
7151 both buffer formatting and unformatting
7152 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7153 unformatting was changed to accomodate following rules:
7154 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7155 sent to the function while XXX_*STRING will not allocate or copy
7156 the data into the buffer. Instead it sets the pointer from the
7157 buffer into the pointer sent as argument (XXX_*STRING used to
7158 require that the pointer must be allocated already). This change
7159 makes this whole thing a bit more consistent and more optimized
7160 (note that the data returned in the unformatting with XXX_*STRING
7161 must not be freed now). The routines return now -1 on error.
7163 o Tried to find all code that use buffer_format and buffer_unformat
7164 and added return value checking to prevent formatting and
7165 especially unformatting errors and possible subsequent fatal
7168 o Changed ske->x and ske->KEY to mallocated pointers in
7169 lib/silcske/silcske.h. Fixed possible data and memory leak.
7171 o Added return value checking to all *_parse* functions. Fixed
7172 many memory leaks as well.
7174 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7175 so that buffer overflows would not happen. All code now also
7176 checks the return value as it can fail.
7178 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Added reconnection support to server if the normal server looses
7181 its connection to the router (for example if router is rebooted).
7182 The server performs normal reconnection strategy implemented
7183 to the server. Affected file silcd/server.c.
7185 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7187 * Added new packet type SILC_PACKET_SET_MODE that is used to
7188 distribute the information about changed modes (for clients,
7189 channels and clients channel modes) to all routers in the
7190 network. Updated the protocol specification accordingly.
7192 Added functions into silcd/packet_send.c and
7193 silcd/packet_receive.c: silc_server_send_set_mode,
7194 silc_server_set_mode.
7196 Added new files silcmode.[ch] into lib/silccore that implements
7197 the encoding and decoding of Set Mode Payload. Added new type
7198 SilcSetModePayload. Moved the definitions of different modes
7199 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7201 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Oops, a little mistake in server's connection authentication
7204 protocol. The protocol is not ended with FAILURE but with
7205 SUCCESS if the authentication is Ok. :) Affected file is
7208 * Implemented NICK_CHANGE notify handling in server in the file
7209 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7210 the local clients on the channel. After the changing nickname
7211 in router environment snhould work and the [<unknown>] nickname
7212 should appear no more.
7214 The silc_server_replace_id function that receives the Replace ID
7215 payload now sends the NICK_CHANGE notify type also in the file
7216 silcd/packet_receive.c
7218 * Changed WHOIS and IDENTIFY command to support the maximum amount
7219 of arguments defined in protocol specs (3328 arguments). This
7220 fixed a bug that caused problems when there were more than three
7223 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Added extra parameter, command identifier, to the
7226 silc_client_send_command so that explicit command identifier
7229 Changed that ID list routines uses specific command identifier
7230 when sending WHOIS/IDENTIFY requests to the server so that they
7231 can be identified when the reply comes back.
7233 Affected files lib/silcclient/command.[ch],
7234 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7236 * Added `sender' argument to silc_server_packet_send_to_channel
7237 to indicaet the sender who originally sent the packet to us
7238 that we are now re-sending. Ignored if NULL. Affected file
7239 silcd/packet_send.[ch].
7241 * Added some server statistics support in silcd/server_internal.h
7242 SilcServerStatistics structure and around the server code. Also
7243 send some nice statistics information when client is connecting
7246 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Fixed channel ID decoding in server's JOIN command reply in
7249 silcd/command_reply.c
7251 * Fixed braodcasting of replace ID payload to not to send it if
7252 we are standalone server in silcd/packet_receive.c.
7254 * Fixed all channel message sending routines to not to send
7255 packets to clients that has router set, since they are routed
7256 separately in the same function earlier. Affects file
7257 silcd/packet_send.c and all channel packet sending functions.
7259 * In USERS reply, res_argv[i] are not allocated, the table
7260 is allocated. Thus changed that free the table, not its
7263 * In server's whois_check and identify_check if the client is
7264 locally connected do not send any WHOIS commands - they are not
7267 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Fixed some minor bugs in client when sending WHOIS command. The
7270 arguments was in wrong order.
7272 * Removed statis function add_to_channel from server in
7273 silcd/command.c that was previously used with the joining but
7276 * Tested USERS command in router environment successfully with two
7277 routers, two servers and two clients.
7279 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Reorganized the USERS command and command reply in client library
7282 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7283 When the command is given by user we register a pending command
7284 callback that will reprocess the command after the reply has been
7285 received from the server. When reprocessing the packet we then
7286 display the information. Thus, the USERS information is displayed
7287 now in the command callback instead of in the command reply
7288 callback. The processing of the command is same as previously
7289 when server has sent the command reply in the JOINing process.
7291 * Added to USERS command in silcd/command_reply.c to join the client,
7292 we didn't use to know about, to the channel after we've created
7293 a client entry for it. Also, for clienet we did know already still
7294 check whether it is on the channel or not and add it if not.
7296 * Removed silc_server_command_join_notify as the function and its
7299 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Changed the client's pending command handling to the same as the
7302 server's pending command handling. It is also now possible to
7303 execute command reply functions from other command reply
7304 function as the function callbacks for commands and command
7305 replies are one and same. The pending commands are not static
7306 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7307 in client connection context. Thus, pending commands are server
7308 connection specific as it is convenient.
7310 Changed the function silc_client_command_pending and
7311 silc_client_command_pending_del and added new function
7312 silc_client_command_pending_check. Removed the
7313 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7316 * Added cmd_ident, current command identifier, to the client
7317 connection context in lib/silcclient/client.h to keep track on
7318 command identifiers used in command sending. Client's command reply
7319 function handling now supports the mandatory command identifiers.
7321 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7322 funtions in client to fully support pending command callbacks.
7324 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7325 as one of the arguments to the application in the command reply
7328 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7329 before first releasing SILC but came back. Now it is removed again
7330 and should come back nomore. The FORWARDED flag was used only
7331 by the JOINing procedure by forwarding the command packet to router.
7332 Now, the JOINing procedure has been changed to more generic (due
7333 to various router environment issues) and FORWARDED is not needed
7334 anymore for anything. The protocol specification is yet to be
7337 Now, removed silc_server_packet_forward from server and the flag
7338 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7340 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Renamed NAMES command to USERS command. The NAMES was named that
7343 due to historical reasons. Now it is renamed. Also, rewrote
7344 parts of the USERS command. The nickname list is not sent anymore
7345 by the server. Only Client ID and mode lists are sent in the USERS
7346 command. Changed this also to the protocol specification.
7348 The client now resolves the names and stuff after it receives
7349 the USERS list from the server when joining to the channel.
7351 * WHOIS and IDENTIFY commands has been changed to support multiple
7352 Client ID's per command. One can now search for multiple users
7353 in the network by sending only one WHOIS or IDENTIFY command.
7354 Changed the code and the protocol specifications.
7356 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7357 uses silc_server_command_whois_parse to parse the request. */
7359 * If normal server, do not parse the WHOIS and IDENTIFY requests
7360 before sending it to the router. Saves some time.
7362 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Fixed JOIN command on client library. Wrong number of arguments
7365 used to crash the client.
7367 * Added silc_server_channel_has_global function to check whether
7368 channel has global users or not.
7370 * Added silc_server_channel_has_local function to check whether channel
7371 has locally connected clients on the channel.
7373 * The silc_server_remove_from_one_channel now checks whether the
7374 channel has global users or not after given client was removed from
7375 the channel. It also checks whether the channel has local clients
7376 on the channel anymore. If it does not have then the channel entry
7377 is removed as it is not needed anymore.
7379 * The silc_server_notify now checks on JOIN notify whether the joining
7380 client is one of locally connected or global. If it is global then
7381 the channel has now global users on the channel and that is marked
7382 to the channel entry. Also, it now saves the global client to
7383 global list who is joining and JOINs it to the channel. This is
7384 for normal server, that is.
7386 Changed silc_server_send_notify_on_channel,
7387 silc_server_packet_relay_to_channel and
7388 silc_server_packet_send_to_channel check if we are normal server
7389 and client has router set (ie. global client) do not send the
7390 message to that client, as it is already routed to our router.
7392 * Implemented LEAVE notify type handling in silc_server_notify
7395 * Tested LEAVE command in router environment successfully. Tested
7396 with two routers, two servers and two clients.
7400 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7402 * Implemented SIGNOFF notify type handling in silc_server_notify
7405 * silc_server_remove_id now removes the client entry from all channels
7406 it has joined and thusly sends SIGNOFF notify type.
7408 * Rewrote the NAMES list generation in server by removing two excess
7409 loops. The lists are created now inside one loop.
7411 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * silc_server_remove_channel_user checks now also global list
7414 for channel and client.
7416 * silc_server_new_channel_user checks now both local and global
7417 list for channel and client. Fixed a bug in client id decoding.
7418 Used to decode wrong buffer.
7420 * silc_server_channel_message checks now both local and global
7421 list for channel entry.
7423 * Tested channel joining (hence JOIN) in router environment
7424 successfully. Tested with two routers, two servers and two
7427 * Tested channel message sending in router environment successfully.
7429 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Added silc_server_save_channel_key into server.[ch] to save the
7432 received channel key in Channel Key payload processing. It is
7433 also used in JOIN command reply handling.
7435 Equivalent function silc_client_save_channel_key added into
7436 client.[ch] into client library.
7438 * Changed JOIN command reply to send information whether the channel
7439 was created or not (is existing already) and the channel key
7440 payload. Changed protocol specs accordingly.
7442 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7443 the request was sent by ID and not by nickname. Crashed on
7446 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7449 now correctly save the received data.
7451 * silc_server_free_sock_user_data now notifies routers in the
7452 network about entities leaving the network.
7454 At the same time implemented functions silc_server_remove_id
7455 and silc_server_send_remove_id to receive and send REMOVE_ID
7456 packets. The packet is used to notify routers in the network
7457 about leaving entities. The ID removed will become invalid in
7460 * Added function silc_idlist_del_server into server. Removes and
7461 free's server entry from ID list.
7463 * silc_server_private_message function now checks, if we are router,
7464 that the destination ID really is valid ID, naturally.
7466 * In router when NEW_ID packet is received (for new client) the
7467 hash of the Client ID is saved in the ID Cache but the
7468 client->nickname is set to NULL, instead of putting the hash
7471 IDENTIFY command now also checks that client->nickname must be
7472 valid. If it is not if will request the data from the server who
7473 owns the client. Added new function
7474 silc_server_command_identify_check.
7476 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7477 to set the command to already allocated Command Payload.
7479 * Tested private message sending in router environment with two
7480 routers, two servers and two clients. Fixed minor bugs and now
7483 * Fixed segfault from client's NAMES command. Used to crash if
7486 * Forwarded packets must not be routed even if it is not destined
7487 to the receiver. Changed server code comply with this.
7489 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7491 * Added `require_reverse_mapping' boolean value to ServerParams
7492 structure. If TRUE (not default) the server will require that
7493 the connecting host has fully qualified domain name.
7495 If the reverse mapping is not required and hostname could not be
7496 found the IP address is used as hostname.
7498 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Implemented version string checking to both client and server.
7501 The check is incomplete currently due to the abnormal version
7502 strings used in development version of SILC.
7504 * Changed all command functions in server to use the new
7507 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Changed char *data to unsigned char *data in ID Cache system to
7510 support binary data as ID Cache data. Changed code to support
7511 binary data in lib/silccore/idcache.c.
7513 * Renamed silc_server_packet_relay_command_reply to
7514 silc_server_command_reply as it is normal packet receiving
7515 function. Rewrote the function to accept command replys for
7516 servers and not only for clients.
7518 * Mark remote router always as registered server if we are connecting
7519 to it. Otherwise, commands sent by the router to us are ignored.
7521 * All ID List find routines now returns the ID Cache Entry pointer
7522 as well if requested.
7524 * WHOIS command works now in router environment, tested with two
7525 routers, two servers and two clients.
7527 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7528 in router environment (as it is almost equivalent to WHOIS) but
7529 hasn't been tested thoroughly. Added new functions:
7531 silc_server_command_identify_parse
7532 silc_server_command_identify_send_reply
7533 silc_server_command_identify_from_client
7534 silc_server_command_identify_from_server
7536 * Disabled route cache adding because adding two different ID's with
7537 same IP replaces the old cache entry thus giving wrong route.
7538 The entry->router->connection is always the fastest route anyway
7539 so route cache may not be needed. Of course, new routes maybe
7540 established after receiving the ID when the entry->router->connection
7541 might not be anymore the most optimal.
7543 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7545 * Add route cache for received ID for fast routing.
7547 * Added silc_server_packet_route to route received packet on router
7548 that is not destined to us.
7550 * Renamed silc_server_get_route to silc_server_route_get.
7552 * Added id_string and id_string_len fields into SilcServer to
7553 include encoded ServerID for fast comparing without excess
7554 encoding of the ID's.
7556 * Cleaned up WHOIS command on server side. Added following static
7559 silc_server_command_whois_parse
7560 silc_server_command_whois_check
7561 silc_server_command_whois_send_reply
7562 silc_server_command_whois_from_client
7563 silc_server_command_whois_from_server
7565 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7566 arguments in command replies. All command functions should be
7567 updated to use this macro.
7569 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7571 * Minor typo fixes on command reply handling on server.
7573 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Added silc_server_command_add_to_channel internal routine to add
7576 the client to the channel after router has created the channel and
7577 sent command reply to the server.
7579 * Added generic silc_server_send_command to send any command from
7582 * Use static buffer with ID rendering instead of duplicating data.
7584 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Fixed a channel user mode bug when joining to a channel server gave
7587 everybody channel founder rights, oops.
7589 * We mark ourselves as the router of the incoming server connection
7590 if we are router ourselves. This way we can check in some packet
7591 sending functions whether it is locally connected server. For
7592 incoming router connections we put NULL.
7594 * For router sending packets locally means now always sending the
7595 packet cell wide; to local clients and local servers. For normal
7596 server sending packet locally means sending it to only local
7599 * Fixed the JOIN command to really work in router environment. If the
7600 channel is created it is always created by the router. Router is
7601 also responsible of making the initial joining to the channel,
7602 sending JOIN notify to the sending server and distributing
7603 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7604 does not exist server doesn't do anything else but forward the
7605 command to the router which performs everything.
7607 * Added silc_server_send_channel_key function to send the Channel Key
7610 * Added silc_server_create_channel_key to create new channel key. The
7611 channel key is now re-generated everytime someone joins or leaves
7612 a channel, as protocol dictates. Note: channel->key_len is the
7615 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7618 packet_receive.[ch] to separate packet sending and receiving
7619 routines. The server.[ch] now includes everything else including
7620 actual packet processing (writing and reading data) and other
7623 Renamed silc_server_private_message_send_internal to
7624 silc_server_send_private_message. The routine is still though
7625 used only to relay private messages as server does not send
7626 private messages itself.
7628 Renamed silc_server_new_channel to silc_server_create_new_channel
7629 and added new function sicl_server_new_channel that handles the
7630 incoming New Channel packet. Added also new sending function
7631 silc_server_send_new_channel to send New Channel Payload.
7633 * Added new function silc_server_notify to process incoming notify
7634 packet to the server/router. Server may then relay the notify
7635 to clients if needed.
7637 * Added new function silc_server_new_channel_user to process incoming
7638 New Channel User packet. Router will redistribute the packet and
7639 send JOIN notify to its local clients and locally connected servers
7640 if needed. Normal server will send JOIN notify to its local client
7641 on same channel when received this packet. Added also corresponding
7642 sending function silc_server_send_new_channel_user to sent the
7645 * Added boolean route argument to send_notif_to_channel and
7646 packet_send_to_channel functions to attempt to route the packet
7647 if it is TRUE and send only locally if it is FALSE.
7649 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * silc_server_replace_id now broadcasts the received replace ID
7652 packet if it is not broadcast packet already. The router must
7653 broadcast to inform other routers about changed ID.
7655 * Added backpointer to server's router into SilcServer context in
7656 silcd/server_internal.h.
7658 * Fixed silc_server_packet_broadcast to send correct broadcast
7661 * The channel key is now distributed to the local client as soon
7662 as it is received from the router (in router environment) so that
7663 no other packet may be sent for the channel until client has
7666 * silc_server_remove_channel_user now broadcasts the received
7667 Remove Channel User packet if it is not broadcast packet already.
7668 The router must broadcast to inform other routers about removed
7671 * Added users field into SilcPacketContext that is a reference count
7672 of the context. One can increase the reference count by calling
7673 silc_packet_context_dup which is now changed to just increase the
7674 reference count instead of duplicating the data. The reference
7675 count is decresed by calling silc_packet_context_free that will
7676 free the data after the reference count hits zero.
7678 For now on the packet context and everything allocated into it
7679 (including the raw packet from network) must be freed by calling
7680 the new silc_packet_context_free function. Added also new function
7681 silc_packet_context_alloc that must be used now to allocate the
7682 context. This also means that if a routine is asynchronous from
7683 silc_[client/server]_packet_parse_type the packet context must
7684 be duplicated by calling silc_packet_context_dup. Otherwise it
7685 gets free'd after silc_[client/server]_packet_parse_type returns.
7686 Also, one must remember that if packet is duplicated then its
7687 reference count must be decresed by calling the free function as
7688 many times as it was duplicated.
7690 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7691 from both client and server.
7693 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7695 * Made joining to a channel working in router environment.
7697 * Cleaned up JOIN command on server side and create function
7698 silc_server_command_join_channel internal routine to make the
7701 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Changed silc_command_pending list to SilcDList. Also, added
7704 `ident' field to SilcServerCommandPending structure to identify
7705 the reply and to call correct callback.
7707 Added silc_server_command_pending_check function to replace the
7708 corresnponding macro. The silc_command_pending list is not
7711 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7712 to set identifier to previously allocated Command Payload. It
7713 is used to set identifier for command when resending Command
7716 * Added silc_command_payload_encode_payload to encode Command
7717 Payload buffer from SilcCommandPayload structure.
7719 * Added silc_argument_payload_encode_payload to encode Argument
7720 payload buffer from SilcArgumentPayload structure.
7722 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7724 * Changed WHOIS command to support router connection on server side.
7725 The whois request is always sent to router unless the server is
7726 standalone server. After server has received the reply from the
7727 router will it send the reply to the client.
7729 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7730 broadcast received broadcast packet. The function is used only
7731 by router. The broadcast packet is always sent to the router's
7734 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7735 render given ID to printable string, for log files for example.
7737 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Made basic router to router connections working. At least they
7740 can now connect to each other but nothing really works the way
7741 they are supposed - yet.
7743 * Added new initiator token to RouterConnection configuration
7744 file in silcd/serverconfig.[ch]. It is used to tell whether we
7745 are the initiator to the remote router or whether we'll expect
7746 the other end to connect.
7748 * Moved registering of listener task to silc_server_init, hence
7749 the server starts listenning as soon as it is run, even if it
7750 does not have connections to other routers. Let's see how well
7753 * Changed default connection retry timeouts for more suitable in
7756 * Removed cipher and such arguments from silc_idlist_add_client
7757 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7758 Added new function silc_idlist_add_data to add the keys and stuff
7761 * Added SilcIDListData structure and added it to SilcClientEntry
7762 and SilcServerEntry as their first field in the structure. This
7763 way we can explicitly cast the ID entries to the SilcIDListData
7764 structure and get common data for the entries. In past, we had
7765 to first check what type of connection it is and then cast it to
7766 correct ID entry type. Now, we can directly cast the opaque
7767 pointer to the SilcIDListData (no matter what ID entry it actually
7768 is) and get the data needed.
7770 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7773 in some circumstances even if threre were timeout tasks, though not
7774 IO tasks, but tasks anyway. Now fixed.
7776 * Defined SilcServerConnection structure to hold connection specific
7777 stuff about directly connected servers and routers. The definition
7778 is currently in silcd/server_internal.h. I thought about having
7779 a bit more important role fro this struct but for now it is used
7780 only when connecting to other server (or router actually).
7782 * Added connecting retry support in server when connecting to
7783 router(s). The retry feature implement exponential backoff
7784 algorithm. Also, added SilcServerParams structure to hold default
7785 parameters for server. For now, it include these retry settings
7786 and are hard coded. After server is moded to be as Silc Server
7787 Library this structure will be more important.
7789 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7791 * Changed client librarys channel->clients table to SilcList and
7792 changed code accordingly.
7794 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7796 * Changed client's channel table to SilcList and changed code
7797 accordingly. Also changed SilcChannelClientEntry to include back-
7798 pointer to the channel so that client entry can use that structure
7799 as list as well and we have fast cross-reference to the channel.
7800 This change dramatically decreased the complexity of channel
7801 handling with client entry and vice versa (removed one extra
7802 loop when searching for channel entry from many functions).
7804 * Changed server->sim from table to SilcDList and changed code
7807 * NAMES command can now be used from user interface. It will show
7808 the user list on the channel, neatly.
7810 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7811 Code now saves realname of the user if it becomes available.
7813 * Renamed configure.in to configure.in.pre and made ./prepare
7814 script to automatically add correct version string to
7815 configure.in which it creates from configure.in.pre.
7817 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * NAMES command reply now shows users mode with the nickname when
7822 * Moved silc_client_ch[u]mode[_char] functions from
7823 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7824 place sucks, they are utility functions and should be in some
7827 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7829 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7832 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Added TRQ (efficient deque and list library) into lib/trq. This is
7837 a very good list library that is currently used in the SILC. Defined
7838 SilcList API over the library because I didn't like the API very
7839 much. See lib/trq/silclist.h for the API and examples of how to
7840 use the API. Fixed various places in the code to use the new
7841 SilcList API. The SilcList is meant for lists that has a structure
7842 already defined as a list. It is not suitable to add just some
7843 context to the list (in TRQ, the context is the list actually).
7845 So, I defined SilcDList that can be used for the purpose where
7846 predefined list structure does not exit. This can be used as
7847 such list. Now some context just can be added to the SilcDList.
7848 Currently this list is not used in the SILC just yet, though there
7849 are a lot places where this can replace dynamically allocated
7850 tables and I will fix these places, later, to use SilcDList.
7851 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7852 and use TRQ internally).
7854 Also fixed some annoying warning messages that the original TRQ
7855 code generated. Also minor changes to TRQ's Makefile.in.
7857 * Added support for querying by Client ID to both WHOIS and
7858 IDENTIFY commands into server, as required by the protocol.
7860 * Removed method function pointers from SilcBuffer structure. They
7861 weren't used to anything and just increased the context size for
7862 no good reason. This change also made silc_buffer_alloc and
7863 silc_buffer_free functions inline functions.
7865 * Disabled command flooding detection support until it's fixed so
7866 that it accepts commands in but does not execute them more than once
7869 * Added silc_net_localhost(), to return local hostname, into
7870 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7871 that must be initialized before calling silc_client_init.
7873 * Added new function: silc_server_send_notify_on_channels to send
7874 notify messages to all channels client has joined. It is assured
7875 that the message is sent only once per client.
7877 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7878 lib/silcutil/silcutil.[ch] as silc_format function. The new
7879 function is generic and is used by server as well, not only by
7880 the logging routines.
7882 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7883 the provided version string was not acceptable. Added new function:
7884 silc_ske_check_version into lib/silcske/silcske.h. The function
7885 must be implemented by the application (client or server) and it
7886 does not reside in the SKE library. The function checks the version
7887 string remote end sent.
7889 * Added back pointers (to opaque context and to SilcSocketConnection)
7890 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7892 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7893 duplicate packet context structure.
7895 * Changed `notify' client operation to send same arguments as client
7896 receives from server except for ID's. ID's are mapped to correct
7897 ID entry and that is returned. Also, if channel entry is not sent
7898 by server but the notify is for channel the channel entry is sent
7899 to application (otherwise application doesn't know that it is for
7900 channel (library gets it from packet's Destination ID)).
7902 * Added silc_client_remove_from_channels into client library to
7903 remove a client from all channels it has joined to. Used when
7904 received SIGNOFF notify from server. Added also new function
7905 silc_client_replace_from_channels to replace old ID entry with
7906 new ID entry on all channels. Used when received NICK_CHANGE
7909 * Fixed ID Cache list handling in silc_idlist_get_client in
7910 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7911 to get (or query) client by ID.
7913 * Updated TODO list.
7915 * Added connection authentication status message defined by the
7916 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7917 support for these into the code in client and server side.
7919 * Added generic function silc_client_send_command to send any command
7920 with variable argument list. Application should use this function
7921 to send commands if the command functions provided by the library
7922 does not suite for the application's user interface needs.
7924 * Added new `failure' client operation. Application is notified about
7925 received failure packet if client is executing a protocol. In this
7926 case the protocol's execution has failed.
7928 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7929 is required by the protocol.
7931 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7932 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7935 * Added status flag to SilcSKE object to indicate realtime status
7936 of the SKE protocol.
7938 * Application receives now exactly same command reply arguments as
7939 the library receives from server. However, if ID is received the
7940 corresponding ID entry is returned to the application (eg. Client
7941 ID is mapped to correct SilcClientEntry entry and that is returned).
7942 Changed command_reply client operation due to this change.
7944 * Changed all ID's in commands and in command replys as ID Payloads.
7945 Change affected both client and server side codes.
7947 All ID's sent in SILC network (with execption of ID's in SILC
7948 Packet header) are sent in ID Payload to support variable length
7951 * Server now notifies nick changes and notifies all clients on
7952 the channels about the new nickname (about the new Client ID,
7955 * Implemented CMODE command to change channel modes. Supports all
7956 channel modes defined by the protocol specs except ban and invite
7957 lists. (Also, private channel key mode is supported but support for
7958 setting private channel key in client is missing, thus, this mode
7959 has no effect on client side (except that server requires that the
7960 client uses private channel key and normal channel traffic does not
7963 Also, invite mode works per se, but INVITE command does not work
7964 yet correctly, so you can set channel as invite only channel but
7965 inviting clients to the channel does not work (it is yet to be
7966 thought what's the best way to do it).
7968 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7969 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7970 Implemented CUMODE command to change user's mode on the channel.
7971 Supports all modes defined by the protocol specs.
7973 * Added NAMES command reply to return users modes on the channel.
7975 * Removed unnecessary and slow ciphers from lib/silccrypt.
7977 * Set SO_KEEPALIVE option to connection sockets by default.
7979 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7981 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7982 redefined the Notify Payload into protocol specs.
7984 * Added silc_id_payload_parse_id to get ID directly from raw
7987 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7989 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7990 accept searching by Client ID as well.
7992 * Added support for LEAVE and SIGNOFF notify types in client library.
7994 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7995 to parse ID Payload from raw data.
7997 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Added flags parameter into silc_ske_assemble_security_properties
8000 function in lib/silcske/silcske.[ch].
8002 * Changed notify client operation to fit better for notify messages
8003 sent by server. The notify payload received from server is now
8004 passed to the application (after parsing it to SilcNotifyPayload).
8005 It is application's responsibility to retrieve the arguments
8006 from the payload and show the message the way it wants. The message
8007 sent by server is implementation specific.
8009 * Changed public keys to comply with the protocol specification.
8010 Old public keys are not supported anymore and are not compatible.
8012 * Removed nickname from Channel Payload as the latest draft removed
8013 it. The client must resolve the nickname from the NAMES command
8014 reply received when it joined the channel.
8016 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8018 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8020 * Fixed some errors in protocol specification drafts.
8022 * Created lib/silccore/silcnotify.c to implement Notify Payload
8023 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8024 generic payloads described by protocol specifications. The file
8025 includes implementations for ID Payload and Argument Payload.
8027 * Changed Command Payload implementation to use the new Argument
8028 Payload. Changed command_xxxx_payload to command_payload_xxxx
8029 to comply with SILC coding conventions.
8031 * Added suppport for Argument Payload handling in Notify Payload
8032 implementation as protocol requires it. Added the new support
8033 into server and client lib as well.
8035 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8037 * Added support for multiple nicknames on same channel. [n] is
8038 added locally to the nickname if there are more than one same
8039 nicknames on the channel.
8041 * Server now sends all nicknames that matched WHOIS request.
8042 Client also shows the list received from server.
8044 * Added TOPIC command to client side. User can now set and show
8045 current topic on channel.
8047 * Added MOTD command to client and server. Also, server sends the
8048 motd when client connects to the server.
8050 * Changed version strings to comply ISO 8601.
8052 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8054 * Fixed protocol error handling in client library. It should now
8055 cope even if the SKE fails for some reason.
8057 * Made new protocol specification drafts for submitting to IETF.
8059 * Implemented TOPIC command to server in silcd/command.c.
8061 * Added two new notify types into lib/silccore/silcnotify.h:
8062 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8063 notify nickname change and topic setting/change on a channel.
8065 * API change of command_reply operation in client library. The
8066 application gets now the status type received from server as well.
8068 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8070 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8072 * Cras fixed and optimized the packet handling even further and
8073 it should work now. Minor change to the prototype of function
8074 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8076 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Added new function into lib/silcutil/silcschedule.[ch]:
8079 silc_schedule_with_fd to select() a specified fd. The function
8080 returns after timeout expires or data arrives or goes. The
8081 function is used by packet routines to wait that all data is
8082 received from network.
8084 * Fixed data reading from network in lib/silccore/silcpacket.c.
8085 The code now assures that all data is read from the fd and then
8086 continues packet processing. This was a bug fix since the code
8087 used to drop some data in some circumstances.
8089 * Added new function into lib/silcclient/client.[ch]:
8090 silc_client_start_key_exchange to start key exchange after
8091 connection has been established to server. The code internally
8092 now uses this funtion but its main purpose was to provide it
8093 for applications that perform their own connecting. After
8094 application has created a connection it merely calls this
8095 function to start the key exchange between client and server.
8096 The library takes care of everything else after that.
8098 Updated also lib/silcclient/README to explain the usage of
8101 * Do not send to application information that connection has
8102 been established. Application gets notified it by connect
8105 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Applied cras's patch to add silc_schedule_one function. The
8108 function runs scheduler once and returns.
8110 * Fixed the scheduler after cras messed it up. The timeout
8111 handling works now as it's supposed to work.
8113 * Added into lib/silccore/ silcnotify.h to include notify
8114 message types support. Changed silc_server_send_notify*
8115 functions, in server.[ch], to support those new notify types.
8116 Added the support for the notify types into client library,
8117 as well. Added new notify client operation into ops.h in
8120 * Changed silc_server_packet_send_to_channel to send normal
8121 packets instead of just channel message packets. The function
8122 is now used to send the notify packets to channels. It is not
8123 used to send channel message packets anymore, as server never
8126 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8127 va_arg()s as it seems to require it nowadays. I guess, if SILC
8128 is compiled with older va_arg() the new code should work anyway.
8130 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8132 * Splitted core library. Core library (lib/silccore) includes
8133 now only SILC protocol specific core (and common) components.
8134 Created new utility library (lib/silcutil) that includes more
8135 generic purpose stuff. The stuff for util library was taken
8136 from the old core library. This was minor and easy split.
8138 * Created SILC Client Library (lib/silcclient) that includes
8139 implementation of the SILC client without user interface. This
8140 was major move from silc/ directory. The code has been changed
8141 so that it is transparent towards the user interface. The
8142 silc/ directory includes now the same user interface as before
8143 and it uses the new client library. Read lib/silcclient/README.
8144 Basicly, the client library performs everything else related
8145 to SILC except user interface handling. Also, configuration
8146 files are considered to be part of user interface and library
8147 does not handle them.
8149 This change also changed a lot of structures, function naming etc.
8150 Most important change was that SilcClientWindow object was
8151 renamed to SilcClientConnection in the client library. Created
8152 also new file lib/silcclient/ops.h. Also added new files
8153 silc/local_command.[ch] and silc/client_ops.[ch].
8155 All these changes were made to make it easier for user interface
8156 designers to create what ever user interface for the SILC client
8159 It is also expected that the server will be moved to lib
8160 directory as well and SILC Server Library will be created;
8161 sometimes in the future.
8163 * Removed Local commands from lib/silccore/silccommand.h as
8164 they are application specific and new client library does not
8165 handle any of those anymore.
8167 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8168 old client implementation in silc/.
8170 * Added support for callback functions in SILC_LOG_* macros.
8171 Application can now set its own callbacks that will be called
8172 instead of using the default functions that will always print
8173 the debug messages to stderr (or stdout). Also, debugging can
8174 now be disabled by setting silc_debug to FALSE and re-enabled by
8175 setting it to TRUE. Note, that logging will still work even
8176 if debugging is disabled.
8178 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8179 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8180 silc_log_reset_debug_callbacks.
8182 * To enable debugging in silc client one must give now -d
8183 option on command line.
8185 * Changed silc_schedule_init to automatically allocate task queues
8186 if they are not allocated before calling it.
8188 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8190 * Added GMP 3.1 into math library.
8192 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8194 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8195 a channel in SILC network. The packet is used by servers and
8196 routers to notify other routers that user has left a channel.
8197 This little feature was missing until now. Added the feature
8198 to protocol specification as well.
8200 Added functions: silc_server_send_remove_channel_user and
8201 silc_server_remove_channel_user into server.[ch].
8203 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8204 lib/silccore/silcpacket.h. However, they are not implemented
8207 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Fixed joining to a channel and sending channel messages
8210 between server and router. The channel message sending should
8211 now work inside a cell.
8213 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8215 * Fixed the private message sending between server and router.
8216 The private message sending should now work inside a cell.
8218 * Added silc_server_replace_id into server.[ch] to replace
8219 existing ID in the SILC network.
8221 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8222 and silc_idlist_replace_server_id into idlist.[ch] in server.
8224 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8226 * Fixed the server to server connections. Server can again now
8227 connect to router. Router to router connections probably does
8230 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8232 * Added dynamic protocol registering support. Now protocols can
8233 registered and unregistered on the fly. Patch by cras.
8235 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8237 * Added lib/contrib directory to hold routines that some platforms
8238 don't have but are needed by SILC.
8240 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8241 into lin/contrib to provide getopt() and getopt_long() for
8242 those who don't have it.
8244 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8246 * Added AWAY command to client. When away message is set and
8247 client receives a private message packet the client automatically
8248 replies to the sender with the away message.
8250 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8251 bug seemed to be the cause of recent problems when compiling
8254 * Added version detection support to SKE protocol specification
8255 and added the new changes to the SKE implementation as well.
8256 There were other minor changes in the SKE protocol as well.
8258 Many changes in lib/silcske/silcske.[ch] and in
8259 lib/silcske/payload.[ch].
8261 * Added ^U functionality, clear input line. Patch from cras.
8263 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8265 * Mainly small bugfixes on core library. Fixed some debugging
8266 logging and buffer overflow in silclog.c.
8268 * Updated config.sub and config.guess on the distribution tree.
8270 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8272 * Added command lagging support in server. Client may execute
8273 commands now only once in two seconds.
8275 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Optimized packet reception. MAC computation and checking is now
8278 also more optimized. A lot previously duplicated code is now
8279 used as generic by both client and server.
8281 * Fixed key pair generation in clientutil.c
8283 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8285 * Added into lib/silccore/silcbufutil.[ch] new function;
8286 silc_buffer_realloc.
8288 * Moved generic packet sending/encryption functions to
8289 lib/silccore/silcpacket.[ch] from client and server. Some
8290 rewriting of the functions.
8292 * Moved all generic packet reception/decryption functions to
8293 lib/silccore/silcpacket.[ch] from client and server. The
8294 packet processing is now much cleaner in both client and server.
8295 These were major changes in both client and server.
8297 * Created many common functions in server to do packet sending.
8298 Previously code were duplicated a lot, this has been removed
8301 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Rewrote major parts of the ID cache system. Don't know
8304 whether it is better now or not but at least the API is more
8307 * Major rewrite on ID cache stuff on client because of the ID
8308 cache API changes. Added idlist.c to client.
8310 * Also major rewrite on ID cache stuff on server as well.
8311 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8312 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8313 in hand, instead they are all put into the ID cache system now.
8314 All server_idlist_* routines uses ID cache now instead of
8315 traversing its own lists (those lists does not exist anymore).
8316 SilcIDList though still exists. Also, SilcXXXEntry's are
8319 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8321 * Finally made the SKE implementation compliant to the protocol
8322 specification. All mp integers are now binary encoded as
8323 opposed being HEX encoded.
8325 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8328 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8329 functions: silc_[encode/decode]_pem. Also added function
8330 silc_encode_pem_file to PEM encode with newlines ('\n') for
8333 * SILC public keys are now encoded either PEM or binary. Same
8334 option is for private keys as well. By default private keys
8335 are binary encoded and public keys PEM encoded. Silly HEX
8336 encoding were removed.
8338 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8339 function to create fingerprints.
8341 * Fixed a bug in SHA1; does not change the original data anymore.
8343 * Partly implemented INFO command on client and server side.
8344 Fixed CLEAR command. Changes to SERVER command; show current
8345 server(s) when giving command without arguments. Added
8346 VERSION command to client.
8348 * Added check to server that unregistered connections cannot
8349 execute commands (unless it is specificly allowed).
8351 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8353 * Fixed screen refresh.
8355 * Fixed channel joining bug from client. On some circumstances
8356 client tried to join to a channel it had already joined.
8358 * Added public key verification process into client's protocol.c.
8359 The client now verifies the public key from user and saves
8360 it into ~./silc/serverkeys/ directory.
8362 Added into: clientutil.[ch]: silc_client_verify_server_key.
8364 * Changed SKE protocol's silc_ske_initiator_finish function
8365 to accept callback function that verifies the received public
8366 key. Removed old silc_ske_verify_public_key function.
8368 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8370 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8371 silc_pkcs_private_key[_data]_set.
8373 * Made the password and public authentication more cleaner in
8374 server's protocol.c.
8376 * Removed historic and obsolete protocol `channel_auth' from
8377 both client and server.
8379 * Removed wrong way of sending command status messages from
8380 server to client in server's command.c. The old way violated
8381 protocol specification.
8383 Changes to silccore/silccommand.[ch]: removed
8384 silc_command_encode_status_payload -> not needed anymore,
8385 changed silc_command_encode_payload_va to accept extra
8386 argument on variable argument list. The argument type must
8387 now be provided to the function. Also, added new function:
8388 silc_command_encode_reply_payload_va which is same as
8389 normal command_encode_payload_va except command status type
8390 is provided as extra argument.
8392 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8394 * Added ~./silc directory handling. The directory includes the
8395 public and private keys for the client.
8397 Added silc_client_check_silc_dir, silc_client_create_identifier
8398 and silc_client_load_keys.
8400 * Implemented SILC protocol compliant public key. Added public
8401 and private key saving to and loading from files.
8403 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8404 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8405 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8406 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8407 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8409 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8410 silc_pkcs_load_[public/private]_key.
8412 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8414 * Added silc_server_get_route (route.[ch]) to get connection
8415 data for the fastest route for given ID.
8417 * Implemented INVITE command on client and server. The command
8418 were re-defined in the SILC Protocol Specification and the
8419 implementation now complies with the specification.
8421 * Implemented PING command on client and server.
8423 * Implemented NAMES command on client and server. The server side
8424 supports currently only normal server not router server yet.
8425 Some changes to NAMES definition in SILC protocol specification.
8427 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8429 * Implemented LEAVE command on client and server.
8431 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8432 again. This change was made to the protocol as well. Server
8433 should not violate the protocol specification anymore.
8435 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8438 was tested. SOCKS4 was not but should work anyway.
