520 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Upgraded the protocol version to 1.1, updated protocol specs
525 * Added the nickname as new argument to NICK_CHANGE notify and
526 added it to protocol specs and implemented it to client and
527 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
528 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
529 lib/silcclient/client_notify.c.
531 * Added the killer's client ID to the KILLED notify and added
532 it to protocol specs and implemented it to client and server.
533 Protocol TODO #13. Affected files are silcd/command.c,
534 silcd/packet_receive.c, packet_send.[ch],
535 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
536 The killer's client entry is now returned to application in
537 the `notify' client operation.
539 * Fixed the Max Argument fields that had too large value set
540 in the protocol specs. Protocol TODO #14.
542 * Added the LEAVE command reply to return the ID of parted
543 channel. Updated protocol specs and implemented it to the
544 client and server. Protocol TODO #15. Affected files are
545 silcd/command.c, lib/silcclient/command_reply.c. The channel
546 entry is now returned to application in the `command_reply'
549 * Rewrote the version SKE version checking in client libary
550 and in server to use the silc_parse_version_string. Affected
551 files are lib/silcclient/protocol.c, silcd/protocol.c.
553 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
554 commands that was missing it, and updated protocol specs and
555 the server implementation. Protocol TODO #10. The affected
556 file is silcd/command.c.
558 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
559 generic reply to a generic request (REQUEST flag), and
560 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
561 way. A draft-riikonen-silc-flags-payloads-00.txt is written
562 to define the payload for DATA flag. Added the flags to
563 the implementation. Protocol TODO #9. Affected file is
564 lib/silccore/silcchannel.h.
566 Changed the client library to return the message length
567 to application as well in the channel_message and private_message
568 client operations. Affected files are
569 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
570 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
571 and lib/silcclient/client_ops_example.c.
573 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
574 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
575 the channel. Updated protocol specs and impelemented this
576 to client and server. Protocol TODO #6. Affected files are
577 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
578 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
580 Added new options m and M to CMODE command in Irssi SILC
581 client to set these modes.
583 * Deprecated all administrative commands from SILC protocol
584 since they are highly implementation specific commands.
585 Updated protocol specs. Moved the old commands in
586 implementations to private range of command types. Affected
587 files are silcd/command.c, lib/silcclient/command.c and
588 lib/silcclient/command_reply.c. Protocol TODO #8.
590 * Fixed a bug in server where sending unknown command crashes
591 the server. Affected file silcd/command.c.
593 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
595 * Added SILC_PROTOCOLVERSION macro to check protocol version
596 of a socket connection. The affected file is
597 lib/silcutil/silcsockconn.h.
599 * Added better error logging in rekey protocol. Affected file
602 * Do not check public key types in SKE during rekey. Affected
603 file lib/silcske/payload.c.
605 * Fixed the rekey protocol with PFS, which was totally broken.
606 Affected file silcd/protocol.c.
608 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Some client implementations quit network by doing first LEAVE
611 and then immediately SIGNOFF (like Bombyx). We now do check
612 after a short time after LEAVE notify and check whether the
613 client is still valid after LEAVE, and if not we remove it from
614 cache. Affected file is lib/silcclient/client_notify.c.
616 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
618 * Merged version 1.1.4 of zlib. Even if it not currently in use,
619 it's good not to have security holes here.
621 * Fixed a negative refcount situtuation for the config context.
622 Affected file is silcd/serverconfig.c.
624 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
626 * ROBOdoc documented lib/silcutil/silcutil.h.
628 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Optimized even more the SilcPacketContext structure. Now
631 totally saved 16 bytes of memory per context after optimization.
632 Affected files are lib/silccore/silcpacket.[ch].
634 * Made strict checks for valid SILC IDs. Affected file is
635 lib/silccore/silcid.c.
637 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Changed the object argument for silc_cipher_register,
640 silc_hash_register, silc_hmac_register and silc_pkcs_register
641 to const. Affected files are lib/silccrypt/silccipher.[ch],
642 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
644 * Changed the silc_get_username and silc_get_real_name to
645 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
647 * Fixed the Irssi SILC Client to use the silc_get_username and
648 silc_get_real_name insted of glib routines since the glib
649 routines only corrupt stack. Fixes the Irssi SILC to work in
650 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
652 * Fixed the Irssi to not use g_get_home_dir since it crashes
653 or returns garbage on cygwin and corrupts stack. Added function
654 get_home_dir to Irssi routines. Affected files are
655 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
657 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
659 * Made some structure optimizations. SFTP memory FS MemFSEntry
660 entry structure. Optimized SilcTask structure. Optimized
661 SilcPacketContext structure.
663 Affected files lib/silcsftp/sftp_fs_memory.c,
664 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
666 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * And yet again reverted back the config thing since Johnny
669 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
672 * Fixed memory leaks from config object. Affected files are
673 silcd/serverconfig.[ch].
675 * Added support for adding new connections to the server in rehash.
676 After rehash they take effect.
678 Added support for changing the maximum allowed connections in
679 rehash. The number can grow but going smaller is not supported.
681 Added function silc_server_num_sockets_by_remote to the
682 silcd/server_util.[ch].
684 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
686 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
688 * Added preliminary checking during config parsing for a valid
689 public/private key and removed further checks in the code.
690 Affected files are silcd/serverconfig.[ch], server.c.
692 * Moved functions silc_server_drop() and silc_server_daemonise()
693 from server.c to silcd.c since they are stricly related to
694 the application activity.
696 * Reverted a small part of the automatic ref/unref since
697 it caused a double unref in some situations. Affected
698 files are silcd/silcd.[ch], server.c, serverconfig.c.
700 * Added some .cvsignore files in the lib directory.
702 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
704 * Fixed silc_net_gethostbyaddr to correctly resolve by
705 address. Affected file lib/silcutil/silcnet.c.
707 * Fixed the notify relaying to client. The HMAC to be used
708 with relayed packets ws wrong and caused decryption failure
709 at the client end. Affected file is silcd/packet_receive.c.
711 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Created new branch silc_protocol_1_0_branch.
715 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
717 * Changed the silc_server_config_* routines to be SilcServer
718 independent. They are now officially application specific code
719 and not part of generic server implementation. Affected files
720 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
722 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Added automatic referencing of config context in the
725 silc_server_config_alloc, and automatic unreferencing in the
726 silc_server_config_destroy. Affected files are
727 silcd/serverconfig.[ch], silcd/silcd.c.
729 * Fixed the silc_log_quick handling in the logging routines.
730 It didn't log quickly when it was TRUE. Affected file is
731 lib/silcutil/silclog.c. Also the flush delay was set even
732 if it was 0 in config file. Affected file is
733 silcd/serverconfig.c.
735 * Added support for changing key pair of the server in rehash.
736 Affected file silcd/server.c.
738 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
740 * Fixed the TOPIC_SET notify to not cras. It changed the topic
741 too early, before getting the channel entry. Affected file
742 is silcd/packet_receive.c.
744 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
746 * Added functions silc_server_config_[ref/unref], these are used
747 to prevent that the config object is destroyed.
749 No longer directly affect global variables silc_log_quick and
750 silc_log_delay, they are first cached inside the config object
751 and then applied with silc_server_config_setlogfiles().
753 silc_server_config_set_defaults() is now internal to
754 serverconfig.c, there are no reasons to show this internal stuff
757 Affected files are silcd/serverconfig.[ch].
759 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
760 fprintf's to stderr, since some code may be executed again after
761 the server went into the background. Affected files are
764 * Added rehash support. Added function silc_server_rehash() that
765 will perform all the basic tasks of the rehashing procedure.
767 * Added command line option `-x, --hexdump'. This will enable the
768 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
769 The option `--hexdump' implies `--debug'.
771 * Fixed a bad bug in the logging APIs (silcutil library) where
772 the application would crash after calling silc_log_reset_all().
774 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Fixed the KICKED notify handling in client library to
777 correctly remove the channel and all entries from the
778 channel when I was kicked. This bug crashed the client.
780 Fixed yet another but in KICKED notify handling to remove
781 the kicked client correctly from the channel.
783 Affected file is lib/silcclient/client_notify.c.
785 * Fixed a minor bug in looking up correct client entry
786 in KICKED notify in server. Affected file is
787 silcd/packet_receive.c.
789 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
790 sources correctly to distribution. Fixes --with-gmp option.
792 * Removed the manual rehashing from ID Cache, and changed it
793 to use the SILC Hash Table's auto rehash feature. Affected
794 file is lib/silccore/silcidcache.c.
796 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
798 * Fixed a bug in the silc_client_nickname_format function that
799 handles the multiple same nickname formatting. Two clients
800 with same nickname caused problems after the first one left
801 and rejoined. It didn't format the nickname correctly.
802 Affected file is lib/silcclient/idlist.c.
804 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
806 * Don't change the topic if olod topic is same as new one.
807 Affected file is silcd/packet_receive.c.
809 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Added cross-reference support to the SILC Documentation
812 generator. All types across all HTML files are now cross-
813 referenced. Affected files util/robodoc/generator.c and
814 scripts/silcdoc/silcdoc.
816 * Added file lib/silcutil/silctypes.h to include all the
817 arithmetic type definitions and some macros. Removed
818 includes/bitmove.h and moved macros to silctypes.h.
820 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
824 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
826 * Added `type' argument to silc_id_payload_parse_id function which
827 now returns the type of the ID to the sent pointer. Affected
828 file is lib/silccore/silcid.[ch].
830 * Added check for CMODE_CHANGE notify type that mode change is
831 allowed by the sender. Affected file silcd/packet_receive.c.
833 * Added check for CUMODE_CHANGE notify type that mode change is
834 allowed by the sender. Affected file silcd/packet_receive.c.
835 Added the ID type as CUMODE_CHANGE notify type as argument
836 to the `notify' client operation. Affected files are
837 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
839 * Added function silc_client_add_server to the client library.
840 Added support for resolving also channel and server info when
841 received unknown entity in notify packet. Affected files are
842 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
844 * Added function silc_command_get_status to return the command
845 status from the command reply's argument payload. Affected files
846 are lib/silccore/silccommand.[ch].
848 * Added check for KICKED notify type that the kicking is
849 allowed by the client. Affected file silcd/packet_receive.c.
851 * Created function silc_get_input which can be used to get input
852 (echo on or off) from user on command line. Affected files are
853 lib/silcutil/silcutil.[ch].
855 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
857 * Optimized silc_server_packet_relay_to_channel function.
858 Added new function silc_channel_message_payload_encrypt which
859 can be called directly if channel message payload needs to
860 be encrypted and is already encoded (no need to call _encode
861 function). Packet relaying is now done by router without any
862 extra memory allocations. Affected files are
863 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
866 * Fixed the INVITE notify handling. It took wrong arguments
867 as invite list and invite delete. Affected file is
868 silcd/packet_receive.c.
870 * Added check for TOPIC_SET notify type that the topic change is
871 allowed by the client. Affected file silcd/packet_receive.c.
873 * Added check for INVITE notify type that inviting is allowed by
874 the client. Affected file silcd/packet_receive.c.
876 * Changed the silc_server_client_on_channel to return the
877 SilcChannelClientEntry as well. Moved the function
878 silc_server_check_cmode_rights to server_util.[ch].
879 Affected files are silcd/server_util.[ch], silcd/command.c.
881 * Added function silc_server_check_umode_rights to check whether
882 changing client's user mode is allowed. Added check for
883 UMODE_CHANGE notify type that the umode change is allowed
884 by the client. Affected files are silcd/server_util.[ch],
885 silcd/packet_receive.c and silcd/command.c.
887 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
889 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
890 ID length. It ignored that ID can be IPv6 based as well.
891 Affected file lib/silccore/silcpacket.h.
893 * Fixed the silc_id_id2str and silc_id_str2id to take the
894 IPv6 address offset's into consideration. Affecte file is
895 lib/silccore/silcid.c.
897 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
899 * Fixed the internal Unix scheduler functions to check for
900 NULL context they may receive. The affected file is
901 lib/silcutil/unix/silcunixschedule.c.
903 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
905 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
906 can specify different directory with --home command line
907 parameter. Affected files irssi/src/silc/core/client_ops.c,
910 * SILC-specific commands aren't now executed if the active server
911 isn't of SILC-type, so there won't be problems with having
912 IRC and SILC protocol support in same client. Affected files
913 irssi/src/silc/core/silc-channels.c, silc-servers.c,
916 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
918 * Improved the signal support in SILC Schedule. Added new
919 function silc_schedule_signal_call which is used by application
920 to mark a signal to be called. It is now safe to perform
921 any kind of tasks in signal callbacks since it is guaranteed
922 that the application specified signal callback is called
923 after the signal is over. Affected files are
924 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
926 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
928 * Added `name' field to SilcChannelPrivateKey to represent
929 application given name for the key. Moved also the context from
930 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
931 Added the `name' argument also to the function
932 silc_client_add_channel_private_key.
934 Added function silc_client_current_channel_private_key to set the
935 current channel private key in use.
937 Added "change" command to KEY command which can be used to change
938 the current channel private key. Bound the command also to
941 Also affected files lib/silcclient/client_channel.c,
942 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
944 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
946 * Added silc_rng_get_byte_fast function in to the
947 lib/silccrypt/silcrng.[ch].
949 * Changed the interface of silc_packet_assemble and the
950 silc_packet_send_prepare. If silc_packet_assmble is now
951 called the application does not call silc_packet_send_prepare
952 because the library will call it automatically. These
953 interfaces now also return a reference to the outgoing buffer
954 which includes the assembled packet, which the application can
955 use to encrypt the packet.
957 Affected files are lib/silccore/silcpacket.[ch],
958 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
959 silcd/packet_send.c, server_backup.c and packet_receive.c.
961 * Fixed a packet sending bug on very high load, where outgoing
962 packet queue wasn't handled correctly and packets got corrupted.
963 Affected files are lib/silcutil/*/silc*sockconn.c,
964 lib/silcclient/client.c and silcd/server.c.
966 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
968 * Added macro SILC_PACKET_DATALEN which can be used during
969 packet assembling to check whether the data to be added to
970 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
971 len is truncated until it fits it.
973 Added checks for maximum length of channel message payload and
974 private message payload also.
976 Added checks for maximum packet length in server and in
979 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
980 lib/silcclient/client.c, lib/silccore/silcchannel.c and
981 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
982 lib/silcclient/client_prvmsg.c.
984 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Added silc_server_packet_queue_purge call to the
987 silc_server_disconnect_remote to assure that all data in the
988 queue before disconnecting is sent to the network. Affected
991 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Added the deleting of server's own ID cache entry to the
994 silc_server_free function. Free also everything else that
995 has been allocated in silc_server_init. The affected file
998 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1000 * Added functions silc_parse_version_string, silc_version_to_num,
1001 and silc_ske_parse_version to parse SILC protocol style version
1002 strings. Affected files lib/silcutil/silcutil.[ch] and
1003 lib/silcske/silcske.[ch].
1005 * Added new configuration params: version_protocol, version_software
1006 and version_software_vendor to specify what version the remote
1007 host must at least be to be able to connect to server. The vendor
1008 string can be regex matched too. Added new function
1009 silc_server_connection_allowed to check maximum number of allowed
1010 connections, and allowed versions for incoming connections.
1011 Affected files are silcd/server.c, server_util.[ch] and
1014 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1016 * Added preliminary support for signals in scheduler. The
1017 signals we care about are now blocked always when the scheduler
1018 is locked. This way we can synchronise the use of signal with
1019 scheduler. It is guaranteed that when signal occurs the scheduler
1020 is not locked, and thus new tasks can be safely added to the
1023 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1024 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1025 Added new platform specific routines
1026 silc_schedule_internal_signals_[un]block and
1027 silc_schedule_internal_signal_[un]register.
1029 Added new functions to SILC Schedule API:
1030 silc_schedule_signal_[un]register. Each signal that application
1031 is going to use should be registered to the scheduler.
1033 Affected files are lib/silcutil/silcschedule.[ch],
1034 lib/silcutil/*/silc*schedule.c.
1036 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1038 * Check for unauthenticated client and server in the
1039 silc_server_new_client and silc_server_new_server functions.
1040 Affected file silcd/packet_receive.c.
1042 * Added function silc_string_is_ascii to check whether given
1043 string is 7-bit ASCII string. Affected files are
1044 lib/silcutil/silcutil.[ch].
1046 * Added function silc_id_is_valid_server_id into the
1047 silcd/serverid.c and added checking for valid Server ID's in
1048 silc_server_new_server. The Server ID must always be based
1049 on the server's public IP address.
1051 * Added logging of DISCONNECT packet message in the server.
1052 Affected file silcd/server.c.
1054 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1056 * Changed all library interfaces that use Global RNG to also
1057 accept SilcRng as argument. Affected files are
1058 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1059 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1060 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1061 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1062 lib/silccrypt/rsa.c.
1064 * Added function silc_pkcs_generate_key to the
1065 lib/silccrypt/silcpkcs.[ch] for applications so that they
1066 don't need to do pkcs->pkcs->init calls anymore.
1068 * Remove SilcSocketConnection from the SFTP API since it really
1069 wasn't needed there. The application has the information
1070 saved in its contexts anyway and the SFTP layer doesn't need
1071 know about it. Affected files lib/silcsft/silcsftp.h and
1072 lib/silcsftp/sftp_[server/client].c.
1074 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1078 lib/silcutil/silcutil.c.
1080 * On EPOC the global crypto module lists are not used at all
1081 in the crypto library. Added support for using the constant
1082 algorithm list on EPOC. Affected files are
1083 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1086 * Fixed the handling of third parameter of KICKED notify, since
1087 it was mistakenly updated to SILC Protocol 1.0 even though it
1088 is to be included in 1.1. Since it is not in 1.0 it is not
1089 mandatory, and this fix now handles it only if it is provided,
1090 and it is not error if it is not provided. Affected file
1091 lib/silcclient/client_notify.c.
1093 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1095 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1096 client. Affected file irssi/src/silc/core/client_ops.c.
1098 * Merged with Irssi 0.8.4 from irssi.org CVS.
1100 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1102 * Check for valid socket connection in client entries before
1103 sending any messages. Fixes a crash, but doesn't fix some
1104 other underlaying bug that is lurking there. Affected
1105 file silcd/packet_send.c.
1107 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1109 * $usermode, $cumode and $cumode_space expandos shouldn't do
1110 anything with non-SILC server records. Affected file
1111 irssi/src/silc/core/silc-expandos.c
1113 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Fixed the silc_net_check_[host/local]_by_sock to support
1116 IPv6 bound sockets as well. Now they can return IPv6 addresses
1117 as well. Affected file lib/silcutil/silcnet.c.
1119 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1120 Affected lib/silcutil/unix/silcunixnet.c.
1122 * Fixed ID rendering (at least on some platforms, not NetBSD)
1123 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1125 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Added silc_hash_public_key and silc_hash_public_key_compare
1128 functions to be used with SilcHashTable. They can be used to
1129 hash public keys and compare public keys in hash table. Affected
1130 file lib/silcutil/silcutil.[ch].
1132 * Added support for specifying multiple public keys for Client
1133 connection section in server configuration file. This makes it
1134 possible to accept multiple public keys from same host, or to
1135 make a section that accepts any incoming host, and have the
1136 accepted public keys listed in the section.
1138 Added functions silc_sever_[find/get]_public_key, added the
1139 support for this actually to all connection sections but only
1140 the Client section is currently allowed to specify multiple
1143 Affected files are silcd/server.c, server_internal.h,
1144 command.c, protocol.c, server_util.[ch], packet_receive.c.
1146 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1150 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1152 * If silc_debug is TRUE, also output standard logging messages
1153 to stderr with the debug output.
1155 Made silc_log_reset_all() flushing all channels before returning.
1156 Also fixed some documentation typos.
1158 Affected files are lib/silcutil/silclog.[ch].
1160 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Fixed the server to check correctly the amount of connections
1163 from single host, by checking also the type of the connection.
1164 Fixed also the comparison of number of connections and number
1165 of allowed connections. Affected files are silcd/server.c,
1168 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1170 * Fixed the USERS command reply to save the user's mode on the
1171 channel as well. Fixed JOIN command reply to check whether a
1172 client is on channel already and not join it twice. Affected
1173 file lib/silcclient/command_reply.c.
1175 * Added new file silc-expandos.c into irssi/silc/core/ to return
1176 various stuff for various signal for the statusbar etc. updating.
1177 Now Irssi SILC client prints channel user modes etc. on the
1180 * The user mode (like server/router operator changes) is now shown
1181 on the Irssi SILC client's statusbar. The affected files are
1182 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1184 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1186 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1187 to SILC_SCHEDULE_[UN]LOCK macros.
1189 * Added more error printing to logs in server code. Affected
1190 files silcd/server.c and silcd/protocol.c.
1192 * Fixed -S option parsing in Irssi SILC Client. Affected file
1193 irssi/src/silc/core/silc-core.c.
1195 * Added silc_buffer_alloc_size function. Affected file is

1220 * Changed all integer type names:
1221 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1222 to avoid collisions with other libraries using same type names
1225 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1227 * Added `prefer_ipv6' argument to the functions
1228 silc_net_gethostbyname[_async]. If it is TRUE it will return
1229 IPv6 address over IPv4. If FALSE IPv4 address is returned
1230 even if IPv6 address was found. Affected files
1231 lib/silcutil/silcnet.[ch].
1233 * Added support silc_net_create_connection[_async] to fallback
1234 to IPv4 address if IPv6 address could not be used (like if
1235 it doesn't work on a specific system). Affected file in
1236 lib/silcutil/unix/silcunixnet.c.
1238 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1244 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1246 * Added automatic extern "C" { ... } for C++ compilers so the
1247 application does not need to define them. Affected file
1248 includes/silcincludes.h.
1250 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1251 old name went against naming convention. Applications now
1252 include "silcclient.h" instead of "clientlibincludes.h".
1253 Removed includes/clientlibincludes.h, it is redundant now.
1255 * Renamed includes/version.h to silcversion.h.
1257 * Added really preliminary support for OS/2 into the util
1258 library. Only thread & mutex API is implemented, others
1259 are still to be implemented. Created the lib/silcutil/os2/
1260 directory. Created also file includes/silcos2.h.
1262 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1269 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1271 * Added proper initializations to silc's irssi code, so it's
1272 now possible to load it as module. Affected files
1273 irssi/src/silc/core/silc-core.c,
1274 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1293 * Added `user_count' to the SilcChannelEntry which now tells the
1294 number of users on the channel. The user count is now saved
1295 in normal server of global channels as well. Affected files
1296 silcd/server.c, idlist.h, packet_receive.c and command.c.
1298 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1299 include file utility functions.
1301 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1302 instead of calling directly OS routines.
1304 * Fixed NICK change printing in Irssi SILC Client. Fixed
1305 KICKED notify printing in Irssi SILC Client. Affected file
1306 irssi/src/silc/core/client_ops.c.

1309 client_entry->channels hash table everytime nick is changed.
1310 Affected file lib/silcclient/client.c.
1312 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1314 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1315 the SKE interface a bit.
1317 * Fixed padding problem in PKCS#1. The padding was not actually
1318 random since the random number generator was used incorrectly.
1319 This security bug affects only when encrypting with PKCS#1, and
1320 it is not currently used at all in SILC. SILC only use signing
1321 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1323 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1335 key_exchange_timeout, conn_auth_timeout, connections_max,
1338 Implemented all the new config settings handling in the server.
1340 Optimized the use of SKE Mutual flag usage. Use it only
1341 if connection authentication protocol is not based in public
1344 Renamed all SilcServerConfigSection* to SilcServerConfig*
1345 to have a bit shorter names.
1347 Affected files silcd/serverconfig.[ch], server.[ch], and

1381 is now done in silc_core_init() which also fixes autoconnecting
1384 Affected files irssi/src/silc/core/silc-core.c,
1385 irssi/src/fe-text/silc.c.
1387 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Added new configuration options and blocks:
1390 keepalive_secs, reconnect_count, reconnect_interval,
1391 reconnect_interval_max, reconnect_keep_trying and
1392 require_reverser_lookup. Added ConnectionParam block, and
1393 implemented the connection parameters when connecting as
1394 initiator and when accepting connections as responder.
1396 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1397 whether given configuration value has been given already.
1399 Affected files silcd/serverconfig.[c], server.[c].
1401 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1402 algorithm parts and created new file silcalgs.conf, that
1403 is now included from the example_silcd.conf.in.
1405 * Optimized the silc_server_connect_to_router_second to take
1406 the connection configuration object from the SilcServerConnection
1407 object instead of finding it during the connecting phase.
1408 Added the configuration object to SilcServerConnection struct.
1409 Affected files silcd/server_internal.h, server.c.
1411 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * Add the client on channel after it was resolved at the
1414 channel message receiving, and it was not already on the
1415 channel. Affected file lib/silcclient/client_channel.c.
1417 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Fixed the public key authentication to allocate always the

1432 config file, allowing both public key and passphrase based
1433 authentication to be set at the same time.
1435 Added `prefer_passphrase_auth' setting in config file which
1436 can be used to set to prefer passwd auth if both passwd and
1437 public key is set. If not set, public key is preferred.
1438 This has effect only when being initiator (responder will try
1441 Added support for authentication with passphrase and public key
1442 at the same time. The passphrase is tried first always since
1443 it is faster to check.
1445 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1447 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1493 * Fixed the file transfer's key agreement payload to include
1494 zero port also if the hostname is NULL because it could not
1497 Call file transfer monitor callback now also if error occurs
1498 during key agreement protocol.
1500 Changed the silc_client_file_send interface to return the
1501 SilcClientFileError instead of session id. The session ID
1502 is returned into pointer provided as argument.
1504 Check that the file exists locally before sending the
1505 file transfer request at all.
1507 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1509 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1510 error than can occur while key agreement protocol. Affected

1519 file lib/silcutil/silclog.c.
1521 * Fixed the channel message payload decryption in the function
1522 silc_channel_message_payload_decrypt to not modify the original
1523 buffer before it is verified that the message decrypted
1524 correctly. Otherwise, next time it is called with correct
1525 channel key it won't encrypt since the payload is corrupted.
1526 Affected file lib/silccore/silcchannel.c.
1528 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1542 become invalid in the callback but it was referenced after
1543 the callback returned.
1545 Do not allow auto rehashing of hash table during the
1546 silc_hash_table_foreach operation, for same reasons as it is
1547 not allowed for SilcHashTableList. Affected files are
1548 lib/silcutil/silchashtable.[ch].
1550 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1556 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1558 * Fixed private message handling. It used some old code that
1559 caused the client to crash. Affecte file is
1560 lib/silcclient/client_prvmsg.c.
1562 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1564 * Added function silc_client_add_channel,
1565 silc_client_replace_channel_id, and removed functions
1566 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1567 from client library.
1569 * Added cross reference of the joined channels to the
1570 SilcClientEntry, and changed the SilcChannelEntry's
1571 users list to SilcHashTable. The affected files are
1572 lib/silcclient/idlist.[ch].
1574 * Fixed a bug in hash table tarversing. While the hash table
1575 is traversed with SilcHashTableList the table must not be
1576 rehashed. It is now guaranteed that auto rehashable tables
1577 are not rehashed while tarversing the list. Also defined that
1578 silc_hash_table_rehash must not be called while tarversing
1579 the table. Added function silc_hash_table_list_reset that must
1580 be called after the tarversing is over. The affected files are
1581 lib/silcutil/silchashtable.[ch].
1583 * Changed all hash table traversing to call the new
1584 silc_hash_table_list_reset in server and in client library.
1586 * Added function silc_client_on_channel to return the
1587 SilcChannelUser entry if the specified client entry is joined
1588 on the specified channel. This is exported to application as
1589 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1591 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed founder regaining problem with JOIN command on normal
1594 server. The notify for mode change must be sent always and
1595 not only if !cmd->pending. Affected file silcd/command.c.
1597 * Fixed the WHOWAS command's reply sending to support the
1598 lists correctly. Affected file silcd/command.c.
1600 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * When sending JOIN command to router for processing the
1603 sender's old command identifier was not saved back to the
1604 sender's command context, fixed now. The affected file is
1607 * Create the key in JOIN command of the router did not return
1608 the channel key, added check for this. Affected file is
1611 * Fixed a channel ID update bug in JOIN command reply. Do
1612 not directly upgrade the ID but call the function
1613 silc_idlist_replace_channel_id if the ID was changed.
1614 Affected file silcd/command_reply.c.
1616 * Fixed memory leaks from command calling if it would fail.
1617 Affected file silcd/command.c.
1619 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1621 * Applied patches from cras:
1623 Memory leak fixes around libaries, irssi window resize fix,
1624 new silclist.h and silcdlist.h, all extern inline changed to
1627 * Removed dotconf from lib/dotconf, not needed anymore.
1629 * Removed TRQ from lib/trq, not needed anymore.
1631 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1632 with server connections. Later this will be configurable
1633 in config file after new config file is done. Affected file
1636 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1638 * Fixed a crash in server related to channel announcements.
1639 Affected file silcd/server.c.
1641 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Fixed memory leaks in silc_server_create_new_channel*
1644 functions. Affected file silcd/server.c.
1646 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1647 which ID was changed. This way the router will send the
1648 user list for the channel again, and server won't be in
1649 desync in some rare circumstances. Affected file is
1650 silcd/packet_receive.c.
1652 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1654 * Check for NULL socket pointer in the function
1655 silc_server_packet_send_to_channel_real. Affected file
1656 silcd/packet_send.c.
1658 * Fixed the BAN notify handling to correctly remove ban
1659 list. Affected file silcd/packet_receive.c.
1661 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1663 * Fixed some header addition to Toolkit distribution in
1664 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1666 * Added lib/silcclient/client_ops_example.h as an template
1667 file for application programmers to quickly start using
1668 the SilcClientOperation functions in their application.
1669 Updated the lib/silcclient/README as well to tell about this
1670 nice file made available.
1672 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1674 * Call silc_server_remove_from_channels when removing client
1675 entry when NO_SUCH_CLIENT_ID was received. Affected file
1676 is silcd/command_reply.c.
1678 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1680 * Added server & router operator statistics updating. Affected
1681 file silcd/packet_receive.c and silcd/command.c.
1683 * Fixed the SERVER_SIGNOFF notify handling on normal server
1684 not to save the history information for clients. Same was
1685 fixed earlier in remove_clients_by_server function, but not
1686 here. Affected file silcd/packet_receive.c.
1688 * Raised the default connection-retry count from 4 to 7 in
1689 server. Affected file silcd/server.h.
1691 * Cancel any possible reconnect timeouts when we start the
1692 key exchange. Affected file silcd/server.c.
1694 * Do not reconnect on connection failure when SCONNECT was
1695 given. Affected files silcd/server.[ch].
1697 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1699 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1701 * Fixed the NICK command to always give the unformatted
1702 nickname to the one giving the NICK command. If unformatted
1703 nickname is cached already it will be formatted and the
1704 local entry will always get the unformatted nickname.
1705 Affected file lib/silcclient/idlist.c.
1707 * Fixed some double frees from client library commands.
1708 Affected file is lib/silcclient/command.c.
1710 * Fixed CUMODE command in server to assure that no one can
1711 change founder's mode than the founder itself, there was a
1712 little bug. Affected file silcd/command.c.
1714 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1716 * Removed the SilcClientCommandDestructor from the client
1717 libary, it is not needed anymore. Affected files are
1718 lib/silcclient/silcapi.h, command[_reply].[ch],
1719 client_notify, idlist.c.
1721 * Fixed GETKEY command to first resolve client, and then
1722 resolve the server only if the client was not found, instead
1723 of resolving both at the same time. Affected file is
1724 lib/silcclient/command.c.
1726 * Added silc_client_start_key_exchange_cb and lookup the
1727 remote hostname and IP address before starting the key
1728 exchange with server. The affected file is
1729 lib/silcclient/client.c.
1731 * The server's public key is now saved using the IP address
1732 of the server and not the servername for the filename.
1733 The hostname public key filename is checked as an fall back
1734 method if the IP address based filename is not found.
1736 Fixed the GETKEY command to save the fetched server key
1737 in correct filename.
1739 Print the remote server's hostname now when new key is
1740 received during connection process. Affected file is
1741 irssi/src/silc/core/client_ops.c.
1743 * Return always our own public key to the client if it asks
1744 for it with GETKEY command. Affected file silcd/command.c.
1746 * Removed the use_auto_addr variable from default config
1747 file since it was in wrong section. Affected file is
1750 * Fixed TOPIC_CHANGE notification to not route it when it
1751 was sent using silc_server_send_notify_to_channel function.
1752 Affected file silcd/command.c.
1754 * Fixed silc_server_send_notify_kicked to send the kicker's
1755 Client ID also, it was missing. Affected files are
1756 silcd/command.c, silcd/packet_send.[ch].
1758 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1760 * Do not save client history information in SERVER_SIGNOFF.
1761 Fixes the bug in normal server that it does not detect
1762 the client becoming valid after the server becomes back
1763 online. Affected file silcd/server_util.c.
1765 * Added `sock_error' field into the SilcSocketConnection
1766 context. When error occurs during socket operation (read
1767 or write) the error is saved. Added also new function
1768 silc_socket_get_error to return human readable socket error
1769 message. Affected files are lib/silcutil/silcsockconn.[ch],
1770 lib/silcutil/unix/silcunixsockconn.c, and
1771 lib/silcutil/win32/silcwin32sockconn.c.
1773 * The server now prints the socket error message in the
1774 signoff for client. Affected file silcd/server.c.
1776 * Fixed the `created' channel information sending from router
1777 to server in JOIN command. Checks now whether the channel
1778 really was created or not and set it according that.
1780 Fixed the JOIN command to use the client entry's current
1781 ID during the joining procedure instead of the one it sent
1782 in the command (it is checked though), since it can change
1783 between the packet processing and command processing, and
1784 would just case unnecessary pain in the client end. Affected
1785 file silcd/command.c.
1787 * Fixed a channel key payload sending to use correct channel
1788 ID when the server was forced to change the channel's ID by
1789 router. Router sent the key payload with the old Channel ID.
1790 Affected file silcd/packet_receive.c.
1792 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1794 * Call silc_server_save_channel_key only if the key payload
1795 was provided in the JOIN command's command reply. Affected
1796 file silcd/command_reply.c.
1798 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1800 * Fixed silc_mp_sizeinbase to return the value correctly with
1801 MPI. Affected file lib/silcmath/mp_mpi.c.
1803 * Fixed the stop_server signal to correctly stop the scheduler
1804 and gracefully stop the server when SIGTERM or SIGINT signals
1805 are received. Affected file silcd/silcd.c.
1807 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1809 * Simple handling of TERM and HUP signals. Also added some log
1810 flushing call around. Affected file is
1813 * Fixed small bugs in silclog.c. Now buffering output will take
1814 effect after 10 seconds since startup: This will ensure that
1815 no important startup messages are lost. Also output redirection
1816 will preserve original format ([Date] [Type] message).
1817 Affected file is lib/silcutil/silclog.c.
1819 * Added two options to the config file, in the logging section:
1820 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1821 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1823 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1825 * Do not print the warning about log files not being initialized
1826 more than once to avoid excess logging. Affected file is
1827 lib/silcutil/silclog.c.
1829 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1830 the SIM copying in make install in Makefile.am.pre.
1832 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1834 * Rewritten silclog APIs. Globally interesting changes follows:
1835 silc_log_set_files() changed to silc_log_set_file().
1836 silc_log_set_callbacks() changed to silc_log_set_callback().
1837 ROBOdoc documented silclog header file.
1838 SilcLogCb now returns bool to wether inihibit the default
1839 handler or not (to keep the old behaviour return always TRUE).
1840 The new APIs should also fix the problem of the
1841 silcd_error.log file that was written in the current directory.
1844 Log files streams will remain opened after silc_log_set_file()
1845 call, means less CPU usage notably on high traffic servers.
1846 File streams are now full buffered, and flushed to the disk
1847 every 5 minutes, lesses HD activity and CPU usage.
1848 Messages can be redirected, allowing admins to configure
1849 one single logfile for all server messages.
1850 the silc_log_quick global variable to activate fast-logging.
1851 Affected files lib/silcutil/silclog.[ch]
1853 * Changed some code to conform new silclog APIs. Affected
1854 files are doc/example_silcd.conf.in, silcd/server.c
1855 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1858 * Fixed a memory leak that could occur in some situations.
1859 Affected file silcd/serverconfig.c.
1861 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1863 * Added the silc_client_del_client to remove the client from
1864 all channels as well. Affected file lib/silcclient/idlist.c.
1866 * Fixed the client library to correctly remove the client
1867 from all channels when the client entry is being destroyed.
1868 Affected file lib/silcclient/client_notify.c, command.c.
1870 * Added auto-nicking support to the client library. If the
1871 applicatio now sets client->nickname it will be sent to the
1872 server after connecting by the library. This way for example
1873 SILCNICK (or IRCNICK) environment variables will have effect
1874 and always change the nickname automatically to whatever
1875 it is wanted. Affected file lib/silcclient/client.[ch].
1877 * Renamed silc_server_command_bad_chars to the
1878 silc_server_name_bad_chars and moved it to the
1879 silcd/server_util.[ch]. Added also new function
1880 silc_server_name_modify_bad to return nickname that
1881 includes bad characters as new nickname without those
1882 bad characters. This check and modify is now used in
1883 silc_server_new_client when the username is initially set
1884 as nickname, so it must be checked to be valid nickname.
1885 Affected file silcd/packet_receive.c.
1887 * The nickname length is now taken from the packet for real
1888 and not trusted to strlen() since it clearly can return
1889 wrong length for nickname including bad characters. This
1890 also applies to channel names. Affected file silcd/command.c.
1892 * Removed the lib/silcsilm/modules directory. Modules are now
1893 compiled into the lib/silcsim. Fixed the copying of the
1894 modules to follow symbolic links in Makefile.am.pre.
1896 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1898 * Fixed silc_string_regexify list creation. Fixes bugs with
1899 BAN and INVITE commands in server. The affected file is
1900 lib/silcutil/unix/silcunixutil.c.
1902 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Removed the command destructor entirely from the server's
1905 command and command reply routines. It is not needed, and
1906 its usage was buggy and caused crashes. Affected files are
1907 silcd/command[_reply].[ch].
1909 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Cancel protocol and NULL sock->protocol if timeout
1912 occurred during protocol. Affected file silcd/server.c.
1914 * Cancel protocol timeouts always before calling the final
1915 callback, to assure that after final callback is called
1916 no other state will be called for the protocol anymore.
1917 Affected file silcd/protocol.c.
1919 * Print error log if incoming connection configuration could
1920 not be found. Affected file silcd/server.c.
1922 * Fixed JOIN command to correctly save the founder mode
1923 to the client on normal SILC server, when the channel
1924 was created by the router. Affected file silcd/command.c.
1926 * Fixed LIST command (hopefully) to send correct reply
1927 packets. Affected file silcd/command.c.
1929 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * The silc_packet_receive_process now returns FALSE if the
1932 read data was invalid packet, and TRUE if it was ok.
1934 The server now checks that if unauthenticated connection
1935 sends data and its processing fails the server will close
1936 the connection since it could be a malicious flooder.
1938 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1940 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Make sure the warning about error opening a log file is
1943 printed only once and not everytime it fails (produces
1944 too much useless log). Affected file lib/silcutil/silclog.c.
1946 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1948 * Made the silc_server_daemonise() function more readable.
1949 Affected file silcd/server.c.
1951 * Pid file is now optional, the user may comment it out from
1952 the config file. Removed define SILC_SERVER_PID_FILE, we
1953 don't need a default any longer. Affected file
1954 configure.in.pre, lib/Makefile.am.pre.
1956 * Make some use of the pid file. The server now dies at startup
1957 if it detects a valid pid file on his path. The server would
1958 die anyway in this circumstance, because of the bind() failure.
1959 Affected file silcd/silcd.c.
1961 * No longer compiling lib/dotconf.
1963 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Fixed JOIN command parsing not to crash. Affected file
1966 lib/silcclient/command.c.
1968 * Fied the NICK_CHANGE notify to add the new client entry
1969 even it is resolved. This removes an <[unknown]> nick
1970 thingy bug in the client. Affected file is
1971 lib/silcclient/client_notify.c.
1973 * Do not try to allocate 0 bytes (efence does not like it)
1974 in lib/silccore/silccomand.c when encoding payload.
1976 * Do not take IRCNICK as nickname in Irssi SILC client since
1977 it is not possible to set nickname before hand connecting
1978 the server (TODO has an entry about adding auto-nicking
1981 * Changed the silc_server_command_pending to check whether
1982 there already exists an pending entry with the specified
1983 command, command identifier and pending callback. This is
1984 to fix IDENTIFY and WHOIS related crashes that may register
1985 multiple pending commands with same identifier. Affected
1986 file silcd/command.c.
1988 * Fixed the server to reconnect to the router even if it
1989 was already reconnecting and EOF was received. This to
1990 fix a possibility that the server wouldn't ever try to
1991 auto-reconnect to the router. Affected file silcd/server.c.
1993 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Fixed the server's password authentication to use the
1996 length of the locally saved password, and not the one
1997 sent in the packet. Affected file silcd/protocol.c.
1999 * Fixed same password authentication problem in the
2000 Authentication Payload handling routines in
2001 lib/silccore/silcauth.c.
2003 * Yet another password authentication problem fixed with
2004 channel password handling in silcd/command.c.
2006 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * If first character of string in silc_parse_userfqdn is '@'
2009 then do not parse it. Affected file is
2010 lib/silcutil/silcutil.c.
2012 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Fixed minor bug in IDENTIFY command reply sending, which
2015 caused various weird problems during JOIN when it was
2016 resolving names for users. Affected file silcd/command.c.
2018 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Fixed the IDENTIFY command reply sending to chech better valid
2021 clients. It was possible to send incomplete list of replies.
2022 Affected file silcd/command.c.
2024 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Added silc_client_command[s]_[un]register functions now to
2027 dynamically register the commands in client library. Removed
2028 the static table of commands. This allows the client library
2029 to call commands without causing the application to know about
2030 what commands library has called.
2032 Removed the INFO command reply kludge to detect when the command
2033 was called by library. Now library use its own command reply
2034 function for INFO command.
2036 Added function silc_client_command_call to call a command.
2037 Application can use it to call command, not access the structure
2040 Now all commands that are sent by the client library (not
2041 explicitly sent by application) use own command reply functions.
2043 Affected files around lib/silcclient/ and in
2044 irssi/src/silc/core/.
2046 * Fixed the WHOIS command reply sending to chech better valid
2047 clients. It was possible to send incomplete list of replies.
2049 Fixed the WHOIS and IDENTIFY to send the request to router
2050 if normal server did not do it and did not find any results.
2052 Affected file silcd/command.c.
2054 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Moved the internal data from SilcClient context into its
2057 own file, not accesible to application. Affected files
2058 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2059 and other files in client library.
2061 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Added doc/examples installation target in Makefile.am.pre.
2066 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2069 commands the found client entry will be removed from the
2070 cache, after notifying application about the error. Affected
2071 file lib/silcclient/command_reply.c.
2073 * Changed the /MSG to check for exact nickname user gave, and
2074 not let `nick' match `nick@host' if it is only one found. Now,
2075 user must type the exact nickname (like nick@host2) even if
2076 there are no more than one same nicks found. This is to avoid
2077 a possibility of sending nickname to wrong nickname since
2078 `nick' could match `nick@host'. Affected file is
2079 irssi/src/core/silc-servers.c.
2081 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Do not print "you are now server operator" or similar when
2084 giving /away command. Affected files are
2085 irssi/src/silc/core/client_ops.c, silc-servers.h.
2087 * Made the silc_server_command_pending_error_check to send
2088 the same command reply payload it received back to the
2089 original sender of the command. This way all arguments
2090 that was received by the server will be received by the
2091 client too. Affected file silcd/command.c.
2093 * Added the silc_idcache_add to return the created cache entry
2094 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2096 * Add global clients to expire if they are not on any channel.
2097 This is because normal server will never know if they signoff
2098 if they are not on any channel. The cache expiry will take
2099 case of these entries. This is done by normal servers only.
2100 The affected files are silcd/command_reply.c,
2101 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2103 * If server receives invalid ID notification for WHOIS or
2104 IDENTIFY and the ID exists in the lists, it is removed.
2105 Affected file silcd/command_reply.c.
2107 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2108 in client then client entry that it matches is searched and
2109 the nickname is printed on the screen for user. Affected
2110 file irssi/src/silc/core/client_ops.c.
2112 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Use cache entry expire time in the LIST command reply to
2115 purge old entries from the cache after the LIST command
2116 reply has been received. This way we don't have non-existent
2117 entries in the cache for too long. Affected file is
2118 silcd/command_reply.c.
2120 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * If we are normal server, and we've not resolved client info
2123 in WHOIS or IDENTIFY from router, and it is global client,
2124 we'll check whether it is on some channel. If it is not
2125 then we cannot be sure about its validity and will resolve it
2126 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2127 file silcd/command.c.
2129 * Search channel by name (if possible) rather than by ID
2130 in IDENTIFY command's command reply. Affected file is
2131 silcd/command_reply.c.
2133 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2136 Updated specs and implemented it. Affected file silcd/command.c,
2137 silcd/packet_send.c and silcd/packet_receive.c.
2139 * Implemented the <founder auth> payload handling in the JOIN
2140 command. If provided all conditions for channel joining
2141 except requirement to provide correct passphrase can be
2142 overrided by the channel founder. Updated the protocol specs.
2143 Affected file silcd/command.c.
2145 Added support for founder auth in JOIN command in client
2146 library. Fixed the parsing of the JOIN command now to support
2147 all options as they should be. The affected file is
2148 lib/silcclient/command.c.
2150 * Optimized the WHOIS and IDENTIFY commands to send the request
2151 to router only if it includes nicknames or other names. If
2152 they include only IDs then check the local cache first before
2153 routing. Affected file is silcd/command.c.
2155 * Added channels topic announcements. Affected file is
2156 silcd/packet_receive.c and silcd/server.c.
2158 * Fixed the silc_server_send_notify_topic_set to really destine
2159 the packet to channel. Affected file silcd/packet_send.c.
2161 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2162 library. Affected file lib/silcclient/client_notify.c.
2164 * Added UMODE announcements. Affected file silcd/server.c.
2166 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Memory leak fixes in:
2170 lib/silcutil/silcsockconn.c
2171 lib/silcske/silcske.c
2172 lib/silcske/groups.c
2174 lib/silccrypt/silcpkcs.c
2175 lib/silccore/silccommand.c
2176 lib/silccore/silcidcache.c
2181 * ROBOdoc documented the lib/silcske/groups.h file and a
2182 bit changed the interface for better.
2184 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2186 * Update the client entry context in the ID cache after
2187 nick change. Affected file lib/silcclient/command.c.
2188 Fixes the CUMODE command when regaining founder privileges,
2189 and a little WHOIS problem.
2191 * Fixed silc_net_gethostbyname to correctly call the
2192 inet_ntop. Affected file lib/silcutil/silcnet.c.
2194 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2196 * Added IPv6 support checking to the configure.in.pre, added
2197 also --enable-ipv6 option to override the check. Affected
2198 file configure.in.pre.
2200 * The silc_thread_create now calls the start function
2201 directly if threads support is not compiled in. Removes
2202 ugly #ifdef's from generic code. Affected files are
2203 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2205 * Added silc_net_gethostby[name/addr]_async to asynchronously
2206 resolve. Affected files are lib/silcutil/silcnet.[ch].
2208 * Added support for rendering IPv6 based server, client and
2209 channel IDs. Affected file lib/silcutil/silcutil.c.
2211 * Added support for creating IPv6 based server IDs. Affected
2212 file is silcd/serverid.c.
2214 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2216 * Added silc_net_gethostby[addr/name] into the
2217 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2218 routines. Added silc_net_is_ip[4/6]. Affected file is
2219 lib/silcutil/unix/silcunixnet.c. All routines that take
2220 address as argument now supports both IPv4 and IPv6 addresses.
2222 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2224 * Fixed LIST command reply sending in server. Affected file
2227 * Server now sends the kicker's client ID in the KICK notify
2228 to the kicked client. Affected file silcd/command.c.
2230 * The client library now parses the kickers client ID and
2231 UI displays it. Affected files lib/silcclient/client_notify.c
2232 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2234 * Made all payload parsing function prototypes consistent.
2235 They all take now const unsigned char * and uint32 pair as
2236 the payload data instead of SilcBuffer. Changes all around
2237 the source tree. Other unsigned char* -> const unsigned char*
2238 changes around the tree as well.
2240 * Optimized SFTP client and server packet sending not to
2241 allocate new buffer for each packet but to recycle the
2242 first allocated buffer. Affected files are
2243 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2245 * Optimized the SFTP client to use SilcList instead of
2246 SilcDList for requests, because it is faster. Affected file
2247 is lib/silcsftp/sftp_client.c.
2249 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2250 into lib/silccore/silcid.[ch].
2252 Renamed silcpayload.[ch] into silcargument.[ch].
2254 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * If client entry is deleted with active key agreement
2257 session, abort the session.
2259 The silc_client_abort_key_agreement now calls the completion
2260 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2262 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2265 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Don't use __restrict in older GCC's. Affected file is
2268 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2270 * silc_net_localhost now attempts to reverse lookup the
2271 IP/hostname. Affected file lib/silcutil/silcnet.c.
2273 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2274 command. It can be used to gain founder privileges at
2275 the same time when joining the channel.
2277 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2278 kicker's client ID as well. Updated protocol specs.
2280 Defined that the server must send SILC_COMMAND_IDENTIFY
2281 command reply with error status to client who sent
2282 private message with invalid client ID.
2284 Updated the protocol specification.
2286 * Added silc_server_send_command_reply to send any
2287 command reply. Affected file silcd/packet_send.[ch].
2289 * Added silc_id_payload_encode_data to encode ID payload
2290 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2292 * The server now send IDENTIFY command reply with error
2293 status if client ID in private message is invalid. Affected
2294 file silcd/packet_receive.c.
2296 * Save the server key file with server's IP address in
2297 the filename instead of hostname. The affected file is
2298 irssi/src/silc/core/client_ops.c.
2300 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2305 * Added libtool support for compiling shared objects in
2306 lib/silcsim. Affected file configure.in.pre and
2307 lib/silcsim/Makefile.am. Original patch by cras.
2309 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Pid file configuration, and server's config file fixes
2312 patch by toma. Updated CREDITS file.
2314 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Fixed silc_client_channel_message to not try to decrypt
2317 the message twice if it resolved the destination client
2318 information. This could cause of dropping one channel
2319 message. Affected file lib/silcclient/client_channel.c.
2321 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2324 lib/silcclient/client.c. This function is used when the SILC
2325 Client is run under some other scheduler, or event loop or
2326 main loop. On GUI applications, for example this may be
2327 desired to used to run the client under the GUI application's
2328 main loop. Typically the GUI application would register an
2329 idle task that calls this function multiple times in a second
2330 to quickly process the SILC specific data.
2332 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2334 * Fixed silc_server_drop() for dropping the supplementary
2335 groups as well, this could cause a security hole on some
2338 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2343 * Write PID file after dropping privileges. Added -F option
2344 to run server on foreground. A patch by debolaz.
2345 Affected files silcd/server.c, silcd/silcd.c.
2347 * Fixed MOTD to return the MOTD file server name. Affected
2348 file silcd/command.c.
2350 * Added INFO command reply handling to the Irssi SILC Client.
2351 Affected file irssi/src/silc/core/client_ops.c.
2353 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Fixed the silc_idcache_list_* routines to really support
2356 the dynamic list. Fixes a crash. Affected file is
2357 lib/silccore/silcidcache.c.
2359 * Fixed the LIST command reply to really call LIST command's
2360 pending callbacks. Affected file silcd/command_reply.c.
2362 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Update conn->local_entry->nickname after giving NICK
2365 command. Affected file lib/silcclient/command.c.
2367 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2369 * Added the [pid] option to the silcd configuration file
2371 Affected files: serverconfig.[ch] and silcd.c
2373 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Save fingerprint in WHOIS command reply in server.
2376 Affected file silcd/command_reply.c.
2378 * Fixed NICK commands pending callback registration.
2379 Affected file lib/silcclient/command.c.
2381 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Use ++server->cmd_ident when sending commands in server,
2384 instead of random number. Affected file silcd/command.c.
2386 * Fixed GETKEY command reply to call actually GETKEY pending
2387 command callbacks. Affected file silcd/command_reply.c.
2389 * A bit stricter check for nicknames. Check for same nickname
2390 in NICK command also. Affected file silcd/command.c.
2392 * Do not call INFO command everytime client ID changes, only
2393 during first connecting. Affected file lib/silcclient/client.c.
2395 * Set the new nickname only after successful command reply for
2396 NICK command is returned by server. Affected file
2397 lib/silcclient/command.c.
2399 * Remove nicknames from nicklist during server_signoff notify.
2400 Should fix /NAMES bit more. The affected file is
2401 irssi/src/silc/core/silc-channels.c.
2403 * Added `fingerprint' field to the SilcIDListData in the
2404 silcd/idlist.h to hold the fingerprint of the client's
2407 Send the fingerprint of the client's public key in WHOIS
2410 Affected files silcd/command.c, and silcd/idlist.[ch].
2412 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2413 create fingerprint from given data.
2415 * Show the fingerprint of the client's public key in WHOIS.
2416 Affected files irssi/src/module-formats.[ch] and
2417 irssi/src/silc/core/client_ops.c.
2419 * Format the multiple same nicknames also during JOIN and
2420 NICK_CHANGE notifys. Affected file is
2421 lib/silcclient/client_notify.c.
2423 * Do not print error on screen for invalid private message
2424 payload since it can come if someone is sending private
2425 messages with wrong key. Affected file
2426 lib/silccore/silcprivate.c.
2428 * Fixed multiple concurrent /PING crash. Affected file
2429 lib/silcclient/command.c.
2431 * Changed the wrong ID encoding. All IP addresses must be
2432 in MSB first order in encoded format. They were encoded
2433 wrong and was in LSB format. Affected files are
2434 silcd/serverid.c, lib/silcutil/silcutil.c.
2436 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2438 * Call the `connect' client operation through the scheduler
2439 in case of error. Affected file lib/silcclient/client.c.
2441 * Call the `failure' client operation even if the error
2442 occurred locally during a protocol. Affected file is
2443 lib/silcclient/protocol.c.
2445 * Added support of sending LIST command to router from normal
2446 server. This way normal server can get list of all channels
2447 in the network too. Fixed the channel list sending in the
2448 server too. Affected files are silcd/command.c, and
2449 silcd/command_reply.[ch].
2451 * Added silc_server_update_channels_by_server and
2452 silc_server_remove_channels_by_server. They are used during
2453 disconnection of primary router and in backup router protocol.
2454 Affected file silcd/server_util.[ch], silcd/server.c and
2455 silcd/server_backup.c.
2457 * Fixed channel adding to global list in IDENTIFY command
2458 reply in server. Affected file silcd/command_reply.c.
2460 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * If the incoming packet type is REKEY or REKEY_DONE process
2463 that packet always synchronously. Fixes yet another MAC
2464 failed error on slow (dialup) connections. Affected file
2465 lib/silcclient/client.c and silcd/server.c.
2467 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Call check_version SKE callback for initiator too. Affected
2470 file lib/silcske/silcske.c.
2472 * Implemented fix for security hole found in the SKE that was
2473 fixed in the specification few days back; the initiator's
2474 public key is now added to the HASH value computation.
2475 Added backwards support for the old way of doing it too, for
2476 old clients and old servers. Affected file is
2477 lib/silcske/silcske.c.
2479 * Enabled mutual authentication by default in SKE. If initiator
2480 is not providing mutual authentication the responder will
2481 force it. This will provide the proof of posession of the
2482 private key for responder. The affected files are
2483 lib/silcclient/protocol.c and silcd/protocol.c.
2485 * Do not cache anymore the server's public key during SKE.
2486 We do mutual authentication so the proof of posession of
2487 private key is done, and if the server is authenticated in
2488 conn auth protocol with public key we must have the public
2489 key already. Affected file silcd/protocol.c.
2491 * Added new global debug variable: silc_debug_hexdump. If
2492 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2493 file lib/silcutil/silclog.[ch].
2495 * Fixed compilation warning due to char * -> const char *.
2496 Affected files lib/silcutil/silcnet.h, and
2497 lib/silccore/silcauth.[ch].
2499 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Fixed CMODE command when new channel key was created. If
2502 the creation failed the old key was removed. Next time giving
2503 same command would crash the server since the old key was
2504 freed already. Affected file silcd/command.c.
2506 * Fixed the silc_server_announce_get_channels to not crash
2507 on reconnect. Affected file silcd/server.c.
2509 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Added silc_log_set_debug_string function to set a regex
2512 string to match for debug output. Only the function names,
2513 or filenames matching the given debug string is actually
2514 printed. This way it is possible to filter out those debug
2515 strings that user is not interested in.
2517 Fixed a bug in silc_string_regexify.
2519 Affected files lib/silcutil/silclog.[ch], and
2520 lib/silcutil/unix/silcunixutil.c.
2522 * Changed the -d options in both server and Irssi SILC client
2523 to take the debug string as argument. Affected files
2524 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2526 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Added silc_hash_babbleprint to create a Bubble Babble
2529 Encoded fingerprint. The encoding is developed by Antti
2530 Huima (draft-huima-babble-01.txt), and it creates human
2531 readable strings out of binary data. Affected file
2532 lib/silccrypt/silchash.[ch].
2534 * Print the babble print now in addition of fingerprint as well
2535 in Irssi SILC client. Affected files are
2536 irssi/src/fe-common/silc/module-formats.[ch],
2537 irssi/src/fe-common/silc/core/client_ops.c.
2539 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Fixed a security problem found in SKE. The initiator's
2542 public key too is now added to the HASH hash value creation
2543 which is signed by the responder to create the SIGN value.
2544 This will prevent anyone in the middle to lie to the responder
2545 about the initiator's public key. If this is done now, the
2546 man in the middle will get caught. Updated the protocol
2549 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Better installation directory handling. Configure module
2552 paths and other paths automatically to example_silc* files
2553 in doc/. A patch by toma.
2555 * Fixed compiler warning from MPI library, and from SILC RNG.
2558 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2559 It can be configured with ./configure. A patch by toma.
2561 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Find correct make to use in prepare-clean. A patch by
2564 toma. Affected file prepare-clean.
2566 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2568 * Added irssi variables use_auto_addr, auto_bind_ip,
2569 auto_bind_port and auto_public_ip.
2571 * Changed the interface for silc_client_send_key_agreement
2572 in lib/silcclient/silcapi.h
2576 irssi/src/silc/core/silc-core.c
2578 lib/silcclient/silcapi.h
2579 irssi/src/silc/core/silc-channels.c
2580 lib/silcclient/client_keyagr.c
2583 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Added silc_pkcs_public_key_compare to compare two
2586 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2588 * Check that the client who set the founder mode on the
2589 channel is the same client that is giving the founder
2590 mode to itself. It is done by comparing the saved public
2591 key (it is saved even in the authentication is passphrase).
2592 Affected file silcd/command.c.
2594 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Do not process packet for disconnected socket connection.
2597 Affected file lib/silccore/silcpacket.c.
2599 * Process the DISCONNECT packet through scheduler in the
2600 client library. Affected file lib/silcclient/client.c.
2602 * Fixed the silc_client_packet_parse to not to increase
2603 the packet sequence number if the conn->sock and the
2604 current socket connection is not same. This can happen
2605 for example during key agreement when the conn includes
2606 multiple socket connections (listeners). Affected file
2607 lib/silcclient/client.c.
2609 * The sender of the file transfer request now provides also
2610 the pointer (listener) for the key exchange protocol. If
2611 the listener cannot be created then it sends empty key
2612 agreement and lets the receiver provide the listener.
2614 Added `local_ip' and `local_port' arguments to the
2615 silc_client_file_send. If they are provided they are used,
2616 if not then it will attempt to find local IP address, if

2696 preserve the WHOWAS info for the client. Affected file
2697 silcd/server_util.c.
2699 * Fixed SERVER_SIGNOFF notify handling in the server. The
2700 server is now able to process incoming SERVER_SIGNOFF notify
2701 for a server that it doesn't even know about. It will remove
2702 the clients provided in the notify. Affected file
2703 silcd/packet_receive.c.
2705 * Check for partial packet in data queue after every packet that
2706 was found from the queue. Return and wait for more data if
2707 there is partial data in queue. Affected file is

2725 irssi/src/fe-common/silc/module-formats.[ch].
2727 * Wrote a help file for FILE command.
2729 * Added silc_rng_global_get_byte_fast to get not-so-secure
2730 random data as fast as possible. Random data is read from
2731 /dev/urandom if available and from the SILC RNG if not
2732 available. It is used in padding generation. Affected file
2733 lib/silccrypt/silcrng.[ch].
2735 * All packets in client library are now processed synchronously.
2736 Optimized packet processing a lot. Affected file
2737 lib/silcclient/client.c.

2748 * Assure that silc_client_notify_by_server_resolve does not
2749 resolve the client information multiple times. If it cannot
2750 be found by the first it cannot be found at all. Affected
2751 file lib/silcclient/client_notify.c.
2753 * Fixed WHOWAS command reply calling. Affected file
2754 lib/silcclient/command_reply.c.
2756 * Removed all references to silc_idlist_get_client from the
2757 Irssi SILC client since that call is internal call used by
2758 the library. The Irssi SILC client will use now client
2759 retrieval functions found in silcapi.h.
2761 * Fixed a bug in resolving nickname info before sending
2762 private message. It used freed memory. Affected file
2763 irssi/src/silc/core/silc-servers.c.
2765 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Assure my_channels statistics cannot go negative in server.
2768 Affected files silcd/server.c, silcd/server_util.c.

2784 * Added silc_net_localip to return local host's IP address.
2785 Affected file lib/silcutil/silcnet.[ch].
2787 * If key exchange or rekey protocol is active for a connection
2788 parse all packets syncronously since there might be packets
2789 in packet queue that we are not able to process without first
2790 processing packets before them. Affected file silcd/server,
2791 lib/silcclient/client.c.
2793 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2794 whether library should continue processing the packet.
2795 Affected file lib/silccore/silcpacket.h.

2841 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2842 is incomplete and is being resolved, it won't be resolved
2845 Make sure also that USERS command reply does not resolve
2846 twice information. Affected file is
2847 lib/silcclient/command_reply.c.
2849 Make sure that silc_client_get_clients_by_list does not
2850 resolve twice same information.
2852 * Check for valid client->id in the silc_server_free_client_data.
2853 Affected file silcd/server.c.
2855 * Fixed /GETKEY nick@server not to crash if the server entry
2856 is not found. Affected file lib/silcclient/command.c.
2858 * Fixed the silc_server_check_cmode_rights to check the
2859 requested modes correctly. Affected file silcd/command.c.

2864 Affected file silcd/command.c.
2866 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Call the silc_server_udpate_servers_by_server in the
2869 primary router that comes back online in the backup resuming
2870 protocol. Otherwise it routes packets wrong. Affected file
2871 silcd/server_util.[ch], silcd/server_backup.c.
2873 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2876 lib/silcutil/silcbuffmt.[ch].
2878 * Redefined the SILC packet header to include the padding
2879 length. Affected file lib/silccore/silcpacket.[ch].
2881 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2882 length for maximum padding up to 128 bytes). Affected
2883 file lib/silccore/silcpacket.h.
2885 * Removed all backwards support for old 0.5.x MAC thingies.
2886 The SILC packet header change makes it impossible to be
2887 backwards compatible.
2889 * Send the ENDING packet with timeout in the backup resuming
2890 protocol. This is to assure that all routers has connected
2891 to the primary router. Affected file silcd/server_backup.c.
2893 * Changed the RNG to take the first IV from random data. It
2894 used to take it from zero actually. Changed the RNG also
2895 to use /dev/urandom during session. /dev/random is used
2896 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2898 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Changed the SILC packet header to have the first two bytes
2901 (the packet length) encrypted. Affected files aroung the
2902 code tree, lib/silccore/silcpacket.[ch]. Removed the
2903 SilcPacketCheckDecrypt callback. It is not needed anymore
2904 since the silc_packet_receive_process will determine now
2905 whether the packet is normal or special.
2907 * Implemented the unidirectional MAC keys. Affected files
2908 lib/silcske/silcske.c, silcd/protocol.c and
2909 lib/silcclient/protocol.c.
2911 * Implemented the packet sequence number to the MAC computation.
2912 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2913 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2914 lib/silcclient/protocol.c.
2916 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Allow backup router to announce servers. All servers
2919 announced by backup router are added to the global list
2920 automatically. Update hte server's socket to our primary
2921 router also when backup router announces a server.
2922 Affected file silcd/packet_receive.c.
2924 * Do not update the client->router in the function
2925 silc_server_udpate_clients_by_server if the client is on
2926 global list. We might fail to find any specific server
2927 for locally connected clients and local cell clients. They
2928 should still use the `from' and not `to' as client->router.
2929 This fixes backup router resuming protocol. Affected file
2930 silcd/server_util.c.
2932 * Decrease channel statistics count only if the channel
2933 deletion worked. Affected files are silcd/server.c and
2934 silcd/server_util.c.
2936 * Added silc_server_update_servers_by_server to update origin
2937 of all server entries. Used during backup router protocol.
2938 Affected files silcd/server_util.[ch], silcd/server.c. and
2939 silcd/backup_router.c.
2941 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2942 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2943 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2944 lib/silccrypt/silchmac.c.
2946 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Assure that router cannot reroute the same channel message
2949 to the sender. Affected file silcd/packet_receive.c.
2951 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Made better checks that the channel message is not sent
2954 to the router it came from. Affected file is
2955 silcd/packet_send.c. Fixed memory leak too.
2957 * Announce informations for incoming router connection, but
2958 only after checking if it is replaced by backup router.
2959 Affected file silcd/packet_receive.c.
2961 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Fixed the backup resuming protocol to work in multiple
2964 router environment. Affected file silcd/server_backup.c.
2966 * Route packet only to one router in the function
2967 silc_server_packet_send_to_channel. Affected file is
2968 silcd/packet_send.c.
2970 * Fixed silc_server_send_notify_dest to set the broadcast
2971 flag. Fixed the silc_server_send_notify_topic to actually
2972 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2973 Affected file silcd/packet_send.c.
2975 * Changed the SFTP Filesystem interface. Changed the
2976 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2977 the filesystem operation function. The SilcSFTPFilesystem
2978 is now a context that is allocated by all filesystem allocation
2979 functions and it already includes the operations structure
2980 and filesystem specific context. It is given as argument
2981 now to the silc_sftp_server_start. This made the interface
2982 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2983 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2985 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Changed the backup router adding and getting interfaces
2988 in the server. The router that will be replaced by the
2989 specified backup router is now sent as argument. Affected
2990 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2993 * Added silc_net_addr2bin_ne to return the binary form of
2994 the IP address in network byte order. Affected files
2995 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2997 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Check for existing server ID in silc_server_new_server
3000 and in silc_server_connect_to_router_final and remove the
3001 old entry if it exists. Affected file silcd/packet_receive.c,
3004 * Send the channel message always to only one router, either
3005 in upstream or downstream. Affected file is
3006 silcd/packet_send.c.
3008 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Wrote the definition of the backup resuming protocol to the
3011 protocol specification.
3013 * Removed one redundant channel key generation from normal
3014 server during joining procedure. Removed one redundant
3015 channel key sending from server to router during joining
3016 procedure. Affected file silcd/command.c.
3018 * Made minor bugfixes to the backup router resuming protocol.
3019 Affected file silcd/server_backup.c, server.c.
3021 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Added --disable-asm configuration option. Affected files
3024 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3027 * Implemented the backup resuming protocol that is used to
3028 resume the primary router position in the cell after the
3029 primary router comes back online. Affected files
3030 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3031 and silcd/server_util.[ch].
3033 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Sleep two (2) seconds after sending QUIT command to server.
3036 Affected file lib/silcclient/command.c.
3038 * Assure that if outgoing data buffer is pending do not force
3039 send any data. Affected file silcd/packet_send.c.
3041 * Assure that if outgoing data buffer is pending do not force
3042 send any data. Affected file lib/silcclient/client.c.
3044 * Implemented the backup router support when the primary router
3045 goes down. The servers and routers can now use the backup
3046 router as new primary router without loosing connectivity.
3048 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3051 in the server to indicate disabled entry. All data read
3052 from the connection will be ignored and no data is sent
3053 for entry that is disabled. Affected files are
3054 silcd/idlist.h, silcd/server.c.
3056 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3058 * Created SFTP client and server test programs in the
3059 lib/silcsftp/tests directory.
3061 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Implemented memory filesystem (virtual filesystem) for
3064 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3067 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Implemented the SFTP (SSH File Transfer Protocol) to the
3070 lib/silcsftp. It includes SFTP client and SFTP server
3073 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Moved lib/silccore/silcprotocol.[ch] to the
3076 lib/silcutil library.
3078 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3079 take variable argument list pointer as argument. Affected
3080 file lib/silcutil/silcbuffmt.[ch].
3082 * Added silc_buffer_set function that is used to set data
3083 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3084 Affected file lib/silcutil/silcbuffer.h.
3086 * Changed various routines in the core library to use the new
3087 silc_buffer_set instead of allocating new buffer only for
3090 * Added 64-bit value formatting and unformatting support to the
3091 silc_buffer_[un]format routines. Affected file is
3092 lib/silcutil/silcbuffmt.[ch].
3094 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3095 to includes/bitmove.h.
3097 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Fixed channel user mode saving in client library. Affected
3100 file lib/silcclient/command[_reply].c.
3102 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Defined the file transfer to the SILC Protocol. Added
3105 new packet type SILC_PACKET_FTP and defined File Transfer
3106 Payload. The mandatory file transfer protocol is SFTP
3107 (SSH File Transfer Protocol). Affected file in addition
3108 of the internet draft is lib/silccore/silcpacket.h.
3110 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3111 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3112 is used as part of backup router protocol when the primary
3113 router of the cell is back online and wishes to resume
3114 the position as primary router.
3116 * Redefined the MAC generation keys in the protocol. The
3117 same key is not used anymore in both direction. Both
3118 direction will now use different keys for sending and
3119 receiving. This fixes a potential security flaw. This
3120 change causes incompatibilities in the protocol.
3122 * Redefined also the MAC computation from the packet.
3123 An packet sequence number is now added to the MAC
3124 computation. This prevents possible replay attacks against
3125 the protocol. This change too causes incompatibilities
3128 Added `sequence' field to the SilcPacketContext to hold
3129 the current sequence number for the packet.
3131 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Added `created' field to the SilcIDListData in the file
3134 silcd/idlist.h to indicate the time when the entry was
3137 * Added `created' field to the SilcChannelEntry too. Affected
3138 file silcd/idlist.h.
3140 * Added `creation_time' aguments to all the announcement functions
3141 in the server. If it is provided then only the entries that
3142 was created after the provided time frame are actually
3143 announced. Affected file silcd/server.[ch].
3145 * The protocol says that the Channel ID's IP address must be
3146 based on the router's IP address. Added check for this in
3147 the silc_server_new_channel when processing incoming New Channel
3148 Payload. Affected file silcd/packet_receive.c.
3150 * Print out the correct version with --version in SILC client.
3151 Affected file irssi/src/silc/core/silc-core.c.
3153 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Fixed WHOWAS command to check for completnes of the client
3156 entry always, not just when the command is coming from client.
3157 Affected file silcd/command.c.
3159 * Added new function silc_server_packet_queue_purge to purge the
3160 outgoing data queue to the network. After the function returns
3161 it is guaranteed that the outgoing packet queue is empty.
3162 Affected file silcd/packet_send.[ch].
3164 * Purge the outgoing packet queue in the rekey protocol's final
3165 callback to assure that all rekey packets go to the network
3166 before quitting the protocol. Affected file silcd/server.c.
3168 * Added silc_client_packet_queue_parse as similar function as
3169 in server to the client library. The affected file is
3170 lib/silcclient/client.c.
3172 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Splitted silcd/server.c and created silcd/server_util.[ch]
3175 for utility functions.
3177 * Added new socket flag SILC_SF_DISABLED to indicate that the
3178 connection is open but nothing can be sent to or received from
3179 the connection. Affected file lib/silcutil/silsockconn.[ch].
3180 The checking for disabled socket is checked in the low level
3181 silc_socket_write and silc_socket_read functions.
3183 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Allow only nicknames and channel names that fits into the
3186 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3188 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * When processing JOIN command reply in server check that if
3191 the channel exists in our global list we'll move it the local
3192 list. Affected file silcd/command_reply.c.
3194 * Fixed the check whether client is joined on the channel already
3195 in JOIN command. Affected file lib/silcclient/command.c.
3197 * Fixed the JOIN command reply to check whether the channel
3198 already exists. Affected file lib/silcclient/command_reply.c.
3200 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Added silc_ske_status_string to map the SKE error numbers
3203 to readable strings. The affected files are
3204 lib/silcske/silcske[_status].[ch].
3206 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Do not show the private channels on the WHOIS channel list
3209 as it is not allowed by the protocol. The affected file is
3212 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Assure that the packet length digged from the actual packet
3215 is something sensible in the silc_packet_decrypt_rest_special
3216 in lib/silccrypt/silcpacket.c.
3218 * Free and NULL the allocated pointer in silc_hmac_alloc if
3219 the HMAC allocation fails. The affected file is
3220 lib/silccrypt/silchmac.c.
3222 * Print the selected security properties to the log files in
3223 the server. Affected file silcd/protocol.c.
3225 * Add SKE's reference counter even if calling the completion
3226 callback manually. Otherwise it goes negative, although it
3227 does not cause any problems. The affected file is
3228 lib/silcske/silcske.c.
3230 * Remove the client entry with short timeout after giving the
3231 KILL command. Affected file lib/silcclient/command.c.
3233 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3234 case all found clients are already disconnected (WHOWAS would
3235 found them) in the server. Affected file silcd/command.c.
3237 * Update the last_receive (time of last data received) to be
3238 updated only when received private or channel message so that
3239 the idle time showed in WHOIS makes more sense.
3241 * Added boolean field `valid' in to the SilcClientEntry in the
3242 client library to indicate whether the entry is valid or not.
3243 This fixes the nickname change bug on channel when changing
3244 the nickname to be same than the old (like nick to Nick) the
3245 nickname formatter doesn't set the new nick anymore to Nick@host.
3246 Affected file lib/silcclient/idlist.[ch].
3248 * Now actually fixed the nickname changing on disconnection.
3249 Added new function silc_change_nick to the Irssi SILC Client.
3250 Affected file irssi/src/silc/core/client_ops.c,
3251 irssi/src/silc/core/silc-nicklist.[ch].
3253 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Check that the public key exists in the GETKEY command before
3256 trying to encode it. Affected file silcd/command.c.
3258 * Print some notifications on received public keys with GETKEY
3259 command in the Irssi SILC Client. Affected files are
3260 irssi/src/fe-common/silc/module-formats.[ch],
3261 irssi/src/silc/core/client_ops.c.
3263 * Use IDENTIFY command to resolve the server information in the
3264 GETKEY command instead of INFO command. Affected file
3265 lib/silcclient/command.c.
3267 * All command reply functions in the client library now calls
3268 the pending command reply callbacks even if an error has
3269 occurred. The server has done this a long time and now it was
3270 time to move the client library to this as well. Now all
3271 errors can be delivered back to the pending command reply
3272 callbacks if necessary. Affected files are
3273 lib/silcclient/command[_reply].[ch].
3275 * Change the nickname on disconnection back to the username
3276 because in reconnect the server will enforce it to it anyway.
3277 Affected file irssi/src/silc/core/silc-servers.c.
3279 * Fixed a config file parsing bug in the Irssi SILC client.
3280 Affected file irssi/src/silc/core/clientconfig.c.
3282 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * When printing the channel mode on JOIN, verify that the
3285 channel key and channel's HMAC are valid. Affected file
3286 irssi/src/silc/core/client_ops.c.
3288 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3291 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3292 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3294 * Removed channel key rekey task deleting from the function
3295 silc_server_save_channel_key. Affected file silcd/server.c.
3296 Added explicit timeout task context instead that is used to
3297 delete the task if we are registering a new task before the
3298 new task has elapsed.
3300 * When channel key rekey occurs the client library now saves
3301 the old channel key for a short period of time (10 seconds) and
3302 is able to use it in case some is still sending channel
3303 messages encrypted with the old key after the rekey. Affected
3304 file lib/silcclient/[idlist.h|client_channel.c].
3306 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Added check to the silc_server_new_id_real to not accept
3309 new ID if it is the sender's own ID. Affected file is
3310 silcd/packet_receive.c.
3312 * Assure that we do not announce ourself or the one we've
3313 sending our announcements when we're router and are announcing
3314 servers to our primary router. Affected file silcd/server.c.
3316 * Fixed silc_server_command_identify_check_client to assemble
3317 correct WHOIS packet. It send corrupted WHOIS packet and
3318 caused problem with router to router connections. Affected
3319 file silcd/command.c.
3321 Fixed also silc_server_command_whois_check the same way
3322 as for the IDENTIFY command.
3324 * Added new SilcIDListStatus to the server in the SilcIDListData
3325 structure. The status now includes the current status of
3326 the entry (like registered, resolved etc.). Affected file
3327 silcd/idlist.[ch]. Defined a bunch of different status types
3328 as well. This replaced the old boolean registered field as well.
3330 Added resolve_cmd_ident field to the SilcClientEntry structure
3331 too so that if the entry is for example being resolved so
3332 another command may attach to the same pending command reply
3333 without requiring to resolve the same entry again. This concept
3334 should optimize the WHOIS and the IDENTIFY resolving under
3335 heavy load by taking away unnecessary resolving for entries
3336 that are being resolved already.
3338 Added support for adding multiple pending commands for one
3339 command idenfier. Affected file silcd/command[_reply].[ch].
3341 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3342 before deleting the data. Otherwise the hash table will have
3343 freed data in comparison functions. Affected file is
3344 silcd/command_reply.c.
3346 * Fixed silc_idlist_replace_client_id to add the new entry to
3347 the cache with NULL nickname. Otherwise there will be invalid
3348 memory as the nickname after the nickname is freed. Affected
3349 file silcd/packet_receive.c.
3351 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3352 saved into wrong slots because the previous number of entries
3353 was not taken into account. Affected file silcd/idlist.c.
3354 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3356 * If we are router and we receive JOIN notify to a channel that
3357 does not have any users then notified client is marked as the
3358 channel founder, as it is it. The affected file is
3359 silcd/packet_receive.c
3361 * Added to the extended hash table API's table_del_*ext functions
3362 the destructor as argument too, so that the caller can decide
3363 which destructor to use or whether to use destructor at all.
3364 Affected file lib/silcutil/silchashtable.[ch].
3366 * Fixed ID Cache purging. It actually deleted the entries from
3367 the hash table after the data was freed. The hash table ended
3368 up comparing freed memory. The affected file is
3369 lib/silccore/silcidcache.c.
3371 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3373 * Fixed Irssi SILC client's KILL command's HELP syntax.
3375 * The USERS command now resolves the detailed user information
3376 if the userinfo field is missing. Affected file is
3377 lib/silcclient/command_reply.c.
3379 * Do not print error in silc_file_read if the read file does
3380 not exist. Just silently return NULL. Affected file is
3381 lib/silcutil/silcutil.c.
3383 * Fixed the silc_log_output to not wine about NULL filename
3384 and to not create some bogus " " filename. Affected file is
3385 lib/silcutil/silclog.c.
3387 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Fixed various printing bugs on the user interface in the
3390 Irssi SILC Client. Minor changes that were forgotten from
3393 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Fixed the configure.in.pre and the compilation and distribution
3396 environment to support the new autoconf 2.52. That version is
3397 now required to compile the CVS trunk.
3399 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3402 to generally parse user@fqdn format strings. Affected file
3403 lib/silcutil/silcutil.c.
3405 * Added nickname_format and nickname_force_format fields to the
3406 SilcClientParams structure. The first one defines the format
3407 for the nicknames that the library will enforce if the receives
3408 multiple same nicknames. The second one is boolean value and
3409 can be used to force the library to always enforce the format
3410 to the nicknames regardles whether there are multiple nicknames
3411 or not. This configurable formatting was employed to flexibly
3412 support accessing multiple nicknames from the user interface.
3413 The userinterface can now set the nicknames to what ever format
3414 they prefer. Affected file lib/silcclient/silcapi.h.
3416 Added function silc_client_nickname_format to the file
3417 lib/silcclient/idlist.c. It performs the nickname formatting.
3419 Added new field `hostname´ to the SilcClientEntry context.
3420 It holds the hostname of the client. Affected file is
3421 lib/silcclient/idlist.h.
3423 * Irssi SILC Client sets the nicknames in nick@hostn format.
3424 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3425 irssi/src/silc/core/silc-core.c.
3427 The WHOIS printing now also shows both the real nickname and
3428 the formatted nickname so that user knows how to access the
3429 user if there are multiple same nicknames cached. Affected
3430 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3431 printing formatting too to take the hostname now as a separate
3432 argument. The Affected file is
3433 irssi/src/fe-common/silc/modules-formats.[ch].
3435 * Changed the silc_client_get_clients_local to accept the formatted
3436 nickname as argument. It accepts the real nickname too but the
3437 formatted nickname can be used to find the true entry from
3438 multiple entries. Affected file lib/silcclient/silcapi.h and
3439 lib/silcclient/idlist.c.
3441 * Added nickname_format_parse field to the SilcClientParams.
3442 It is a callback function provided by the application to parse
3443 the nickname out of the formatted nickname string. The library
3444 calls it to get the nickname from the formatted string. Since
3445 the application generally knows better the format of the nickname
3446 string it parses it instead of the library, even though library
3447 encodes the formatted string. If the callback function is not
3448 provided then the library will use the string as is. The
3449 affected file is lib/silcclient/silcapi.h.
3451 * All the nickname strings passed to the client library in
3452 commands are now expected to be formatted nickname strings.
3453 If the command does not support the formatted nickname string
3454 it will assume that the sent string is the actual nickname.
3455 Affected file lib/silcclient/command.c.
3457 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Added public key authentication support to OPER and SILCOPER
3460 commands in the client library. Affected file is
3461 lib/silcclient/command.c.
3463 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Changed the get_auth_methdod client operation to be asynchronous.
3466 It can be async if the application resolves the authentication
3467 method from the server during the negotiation. Added new
3468 SilcGetAuthMeth completion callback that the application will
3469 call after resolving the authentication method.
3471 Added function silc_client_request_authentication_method that
3472 the application can use to resolve the authentication method
3473 from the server. Added also SilcConnectionAuthRequest callback
3474 that the library will call after the server has replied. The
3475 application can call this function if it does not know the
3476 current authentication method.
3478 Affected files are lib/silcclient/client.c and
3479 lib/silcclient/silcapi.h.
3481 * The Irssi SILC client now automatically resolves the authentication
3482 method incase any configuration information is not present (and
3483 currently there never is). The affected file is
3484 irssi/src/silc/core/client_ops.c.
3486 * Fixed public key authentication from the client library.
3487 Affected file lib/silcclient/protocol.c. Changed also the
3488 protocol specification about the public key authentication in
3489 the connection authentication protocol. The actual data to be
3490 signed is now computed with a hash function before signing.
3492 * Fixed the public key authentication from the server as well.
3493 Affected file silcd/protocol.c.
3495 * Removed the mlock()'s from the memory allocation routines.
3496 Affected file lib/silcutil/silcmemory.c. The ./configure does
3497 not check anymore for the mlock(). Affected file is
3500 * Fixed USERS command in server to allow the execution of the
3501 command for private and secret channels if the client sending
3502 the command is on the channel. Affected file silcd/command.c.
3504 * Fixed silc_client_get_clients_local to return the clients
3505 count correctly. It could return wrong value. Affected file
3506 lib/silcclient/idlist.c.
3508 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3511 types. The assembler optimizations seemed not to like 64-bit
3512 data types. The assmebler optimizations thus are now enabled
3513 also for BSD systems as opposed to only enable them for Linux.
3515 * Do not check for threads at all on BSD systems. Affected
3516 file configure.in.pre.
3518 * Removed -n and -h options from the Irssi SILC Client since
3519 they are not used in silc.
3521 * Fixed the prime generation to assure that the first digit
3522 of the generated random number is not zero since our conversion
3523 routines does not like number strings that starts with zero
3524 digit. If zero digit is seen the random number is regenerated.
3525 This caused some corrupted RSA keys when the zero first digit
3526 was met. Affected file lib/silcmath/silcprimegen.c.
3528 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Fixed WIN32 configuration in the ./configure script.
3531 Fixed to include xti.h on environments that has it.
3532 Patches by Carsten Ilchmann and andrew.
3534 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3536 * Changed the silc_id_create_client_id to be collision
3537 resistant. It is now assured that there cannot be created
3538 two same client ID's. I suspect that some weird bugs in
3539 the server were actually caused by duplicate Client IDs.
3540 Affected file silcd/serverid.[ch]. A router receiving
3541 new ID now also assures and informs the sending server
3542 if the ID caused collision.
3544 * Changed the silc_id_create_channel_id to also assure that
3545 there are no collisions.
3547 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3549 * Statement about ignoring the Mutual Authentication flag when
3550 performing rekey with PFS was a bit misleading. It is ignored
3551 if it was set in the initial negotiation, it cannot be even
3552 set in the rekey. Fixed in the ke-auth draft. Started the
3553 new versions of the protocol drafts in the doc/.
3555 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Fixed a bug in silc_client_command_identify_save when saving
3558 new channel information. The channel name was no duplicated
3559 and caused crash on exit. Affected file is
3560 lib/silcclient/command_reply.c.
3562 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Fixed the getkey command handling in the server. Send just
3565 empty OK reply to the sender if the key could not be fetched
3566 (but everything else was ok, like the key just was not available).
3567 Changed the public key parameter to optional in the protocol
3568 specs so that empty OK reply can be sent. Affected file
3571 Added a message to Irssi SILC client to tell to user if the
3572 server did not return a public key.
3574 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Fixed a channel key regeneration bug. It registered new
3577 timeout tasks exponentially until all system resources were
3578 used. Affected file silcd/server.c.
3580 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Added the SILC Document generator to the scripts/silcdoc.
3583 It can be used to generate the Toolkit Reference Manual out
3584 of the source tree. Internally it will also use the RoboDoc
3585 generator now imported in util/robodoc.
3587 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Added couple of return's in rekey protocol if error orccurred
3590 during the protocol. The execution must be terminated.
3591 Affected file silcd/protocol.c. Also, terminate the protocol
3592 always with timeout.
3594 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * The client's Client ID was created initally from the wrong
3597 nickname (it could have been in format nick@host) in the
3598 silc_server_new_client. Affected file silcd/packet_receive.c
3600 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Added some SILC_LOG_ERROR's to various error conditions
3603 if client could not be added to ID cache. Affected files
3604 silcd/packet_receive.c and silcd/server.c.
3606 * When client's sock->user_data is freed, NULL also the
3607 client->router and client->connection pointers. Added check
3608 for these pointers being NULL to various places around the
3609 code. Affected file silcd/server.c.
3611 * Added client->data.registered == TRUE checks to various
3612 places around the code to assure that unregistered client's
3613 are not handled when it is not allowed. Affected file
3616 * Added `bool registered' fields to all
3617 silc_idlist_[server|client]_get_* routines to indicate whether
3618 the fetched client needs to be registered or not. Affected
3619 file silcd/idlist.[ch].
3621 * Add your own entry as registered to the ID cache in the
3622 server. Affected file server.c.
3624 * Fixed a bug in silc_server_new_server. The SilcServer was
3625 set as the new server's context instead of SilcServerEntry.
3626 This naturally caused some weird bugs.
3628 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Do not delete the channel rekey task when adding it
3631 for in silc_server_create_channel_key.
3633 * Changed the silc_server_create_channel_key to return
3634 TRUE or FALSE to indicate the success of the channel key
3637 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Fixed MSVC++ project files and added missing files to
3640 Makefiles under win32/.
3642 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * Do not add TCP_NODELAY flag if the operating system
3645 does not have it defined. Affected files are
3646 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3648 * Fixed buffer overflow from Irssi SILC Client. Affected
3649 file irssi/src/fe-common/core/themes.c.
3651 * Fixed double free in client library in the file
3652 lib/silcclient/client.c when disconnecting from server.
3654 * Applied double free patch from cras to Irssi SILC client.
3655 Affected files irssi/src/core/[modules/expandos].c
3657 * Fixed the disconnection handling to Irssi SILC Client.
3658 The application must call silc_client_close_connection
3659 in ops->connect client operation in case of failure of
3660 the connection. Affected file is
3661 irssi/src/silc/core/client_ops.c.
3663 * Do not set sock->protocol to NULL in the function
3664 silc_client_close_connection after executing the protocol's
3665 final callback since the sock might not be valid anymore.
3666 Affected file lib/silcclient/client.c.
3668 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3670 * Do not enable SILC_THREADS if the linking with libpthread
3671 did not happen. Affected file configure.in.pre.
3673 * Added notion to protocol specification that server must
3674 verify the sent authentication payload with CMODE when
3675 setting the channel founder key. Implemented it to the
3676 server. Affected file silcd/command.c.
3678 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3680 * Added _EXTRA_DIST SILC distribution variable to the
3681 distributions file. It is used to conditionally add extra
3682 files or directories to the specific distribution. Affected
3683 files ./prepare, Makefile.am.pre and distributions.

3688 * Added README.WIN32 for instructions to compile the Toolkit
3691 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Fixed a double free in disconnection in the server. Affected
3694 file is silcd/server.c.
3696 * Fixed the lib/silcske/groups.c to work now also with GMP
3697 MP library. The string conversion did not work when using
3698 specific base and the base is indicated in the string as well.
3700 * Created win32/ directory which now includes MSVC++ specific
3701 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3702 It will appear only in the toolkit distribution
3704 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3706 * Changed the key material distribution function in case when
3707 the hash output is too short. The data is now concatenated
3708 a bit differently than it used to. Made the change to the
3709 SKE protocol specification.
3711 * Added better GMP detection to configure.in.pre. A patch
3714 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3716 * Fixed a minor bug in SKE that might cause some problem on
3717 some platforms. Affected file lib/silcske/silcske.c.
3719 * Added the cookie checking for initiator in the SKE. It checks
3720 that the responder returns the sent cookie unmodified. The
3721 affected file is lib/silcske/silcske.c. Added new SKE
3722 error type INVALID_COOKIE that can be sent during the
3723 negotiation. Fixed some memory leaks as well.
3725 * Added the "invalid cookie" error message to Irssi SILC client's
3728 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Added `task_max' field to the SilcClientParams to indicate
3731 the maximum tasks the scheduler can handle. If set to zero,
3732 default values are used. Affected file lib/silcclient/silcapi.h.
3734 * Fixed memory leaks in silc_client_close_connection. Affected
3735 file lib/silcclient/client.c.
3737 * Added silc_client_del_client_entry to client library to free
3738 all memory of given client entry. Affected file is
3739 lib/silcclient/idlist.[ch].
3741 * Added new functions silc_client_del_channel and
3742 silc_client_del_server to delete channel and server entries.
3743 Affected file lib/silcclient/[silcapi.h/idlist.c].
3745 * Removed silc_client_del_client_by_id from silcapi.h.
3747 * Fixed the INFO command to return the server's own info
3748 correctly when querying by Server ID. Affected file is
3751 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3753 * Removed the non-blocking settings in WIN32 code in the
3754 silc_sock_[read/write] and added SleepEx instead. Affected
3755 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3756 of input data is now checked with FIONREAD and ioctlsocket.
3758 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3760 * Call silc_schedule_task_del_by_context in the
3761 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3762 Affected file lib/silccore/silcprotocol.c.
3764 * Call silc_protocol_cancel for active protocols in the
3765 silc_server_close_connection if the funtion
3766 silc_server_free_sock_user_data has not been called.
3767 Affected file silcd/server.c.
3769 * Generic tasks cannot be deleted using the del_by_fd
3770 task deleting function since generic tasks does not match
3771 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3773 * Added a notion to SILCOPER help file that the SILCOPER works
3774 only on router server, not on normal server.
3776 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Added for WIN32 support for the new scheduler as well.
3779 Affected file lib/silcutil/win32/silcwin32schedule.c.
3781 * Fixed the SHA1 implementation to work on various platforms.
3783 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3785 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3786 API. It is part of the scheduler now. Everything else is
3787 as previously but some functions has changed their names.
3788 Checkout the lib/silcutil/silcschedule.h for the interface.
3789 Updated all applications to use the new interface. Affected
3790 files are lib/silcutil/silcschedule.[ch].
3792 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3794 * Found a bug in the SKE implementation. The HASH value,
3795 specified by the protocol, was not computed correctly. The
3796 public key of the responder was not added to the computation
3797 even though it is mandatory. Affected file lib/silcske/silcske.c.
3798 This unfortunately causes incompatibilities with older
3799 clients and servers.
3801 * Added WIN32 specific network init and uninit functions:
3802 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3803 the Winsock2. Affected file lib/silcutil/silcnet.h and
3804 lib/silcutil/win32/silcwin32net.c.
3806 * Set the socket always to nonblocking mode on WIN32 after
3807 reading data or writing data. Affected file is
3808 lib/silcutil/win32/silcwin32sockconn.c.
3810 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Fixed various compilation problems under WIN32. Affected
3813 files lib/silcutil/win32/silcwin32thread.c and
3814 lib/silcutil/win32/silcwin32schedule.c.
3816 * Removed all _internal.h #includes from public header
3817 files. Internal headers must never be included from
3820 Removed also the lib/silcske/payload_internal.h file.
3822 * All include files that may be needed (public and some others
3823 included by the public headers) by application developers are
3824 now copied to the ./includes directory. It does not copy any
3825 internal headers. Affected file Makefile.defines.pre and all
3826 Makefile.am's under lib/ and subdirs.
3828 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3830 * Do not change the ~/.silc directory's permissions automatically.
3831 Affected file irssi/src/silc/core/clientutil.c.
3833 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Do not cancel the protocol in silc_server_close_connection
3836 it might cause recursion. Now cancelled in the function
3837 silc_server_free_sock_user_data. Affected file silcd/server.c.
3839 * Fixed the silc_server_remove_clients_by_server to regenerate
3840 the channel keys correctly finally. Added also new function
3841 silc_server_remove_clients_channels to actually do it.
3842 Affected file silcd/server.c.
3844 * Fixed the silc_server_new_channel to not crash by giving
3845 wrong router to the new channel. Affected file is
3846 silcd/packet_receive.c.
3848 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3851 which is given as argument to the silc_client_alloc now.
3852 It can be used to configure the client and set various parameters
3853 that affect the function of the client.
3855 * The USERS command in server did not check whether the channel
3856 is private or secret. Affected file silcd/command.c.
3858 * Added new argument to the USERS command in protocol specification.
3859 The USERS command now can take the channel name as argument
3860 as well. Added support for this in client and server and
3861 updated the protocol specs.
3863 * Completed the GETKEY command in client. It can be now used
3864 to fetch also servers public key not only some clients.
3865 Affected files lib/silcclient/command[_reply].c.
3867 * Added silc_client_get_server to return server entry by the
3868 server name. Affected files lib/silcclient/silcapi.h and
3871 * Redefined the IDENTIFY command in protocol specification to be
3872 more generic. It now can be used to query information about
3873 any entity in the SILC Network, including clients, servers and
3874 channels. The query may be based either the entity's name
3875 or the ID. Added support for this in both client and server.
3877 Affected files silcd/command.c and lib/silcclient/command.c
3878 and command_reply.c.
3880 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3881 the _from_client and _from_server functions. Affected file
3884 * Added silc_client_get_channel_by_id_resolve to the file
3885 lib/silcclient/silcapi.h to resolve channel information by
3886 its ID. Added also silc_client_get_channel_by_id that
3887 does not resolve it from the server.
3889 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Added SilcServerEntry context into the client library
3892 to represent one server. The INFO command now allocates
3893 these to save the resolved server info. For now on the
3894 client library will also keep information about servers,
3895 connected and resolved with INFO.
3897 The INFO command now allocates the SilcServerEntry context
3898 and saves the server info there. The COMMAND_REPLY in
3899 the INFO now returns the parameters to application in
3900 same order as defined in the protocol specification.
3902 The entries are cached in the client->server_cache.
3904 * The INFO command is now issued after received the Client ID
3905 from the server. Affected file lib/silcclient/client.c.
3907 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3908 to the application as the mode changer might be server.
3909 It is guaranteed that NULL is not returned anymore to the
3910 application. Affected file lib/silcclient/client_notify.c.
3912 The ID Type is now also passed to the application so that
3913 it can check whether the returned entry is SilcClientEntry
3916 Added new function silc_client_get_server_by_id to return
3917 the server entry by ID. Affected files are the
3918 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3920 * Do not create the channel in the Irssi SILC Client when issuing
3921 the JOIN command but when received the sucessful JOIN command
3922 reply. Otherwise the channel might get created even though we
3923 could not join it. The Affected file is
3924 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3926 * Fixed a channel joining bug in router. The router must also
3927 check the channel modes, invite and ban lists etc. when serving
3928 the JOIN command sent by normal server. Affected file is
3929 silcd/command.c. The router now resolves the client's
3930 information from the server who sent the JOIN command if it
3931 does not know it, and processes the JOIN command only after
3934 * Changed the SilcCommandCb to take new argument; void *context2.
3935 Affected file lib/silccore/silccommand.h
3937 The second argument in the command callbacks in the server now
3938 includes the SilcServerCommandReplyContext if the command was
3939 called as pending command callback from the command reply.
3940 Otherwise it is NULL. When called as pending the status of the
3941 command reply will be checked and if it was erronous the
3942 error will be sent to the original sender of the command.
3943 This way the client always receives the error messages even
3944 though the server was actually the one who received the error
3945 when it resent the command to router, for example. Affected
3946 files silcd/command[_reply].[ch].
3948 * Fixed sending WHOWAS command's error message to client if
3949 the requested client could not be found. It was missing.
3952 * Changed the CMODE and CUMODE commands reply arguments in the
3953 protocol specification. The Channel ID is now sent in both
3954 of the commands to identify the channel. Implemented this
3955 new feature to the client and server. Affected files
3956 lib/silcclient/command_reply.c and silcd/command.c.
3958 * Made better checks for invite and ban lists in the JOIN
3959 command in server. Affected file silcd/command.c.
3961 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * The server now performs the incoming host IP/DNS lookup
3964 using the silc_socket_host_lookup and thus does not block
3965 the server anymore. Affected file silcd/server.c.
3967 * Completed the multi-thread support for SILC Scheduler in
3968 the lib/silcutil/silcschedule.c.
3970 * Fixed the configure.in.pre to detect the pthread correctly
3973 * Fixed a deadlock in silc_task_queue_wakeup in the file
3974 lib/silcutil/silctask.c.
3976 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3978 * Added new function silc_schedule_wakeup that is used in
3979 multi-threaded environment to wakeup the main thread's
3980 schduler. It needs to be used when a thread adds a new task
3981 or removes a task from task queues. After waking up, the
3982 scheduler will detect the task queue changes. If threads
3983 support is not compiled in this function has no effect.
3984 Implemented the wakeup mechanism to both Unix and WIN32
3985 systems. Affected files are lib/silcutil/silcschedule.[ch],
3986 lib/silcutil/unix/silcunixschedule.c and the
3987 lib/silcutil/win32/silcwin32schedule.c.
3989 * Added new function silc_task_queue_wakeup to wakeup the
3990 scheduler by the specified task queue. Affected file
3991 lib/silcutil/silctask.[ch].
3993 * The silc_socket_host_lookup_start now wakes up the scheduler
3994 after adding the timeout task. Affected file is
3995 lib/silcutil/silcsockconn.c.
3997 * The silc_socket_host_lookup is synchronous now if the threads
3998 support is not compiled in. However, the callback is still
3999 called asyncronously through the scheduler, anyway. Affected
4000 file lib/silcutil/silcsockconn.c.
4002 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Added new function silc_socket_host_lookup to perform
4005 asynchronous IP and FQDN lookups for the socket connection.
4006 Affected files lib/silcutil/silcsockconn.[ch].
4008 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4010 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4011 that may or may not compile the mutex support in.
4013 Changed the silc_mutex_alloc interface. It allocates the
4014 mutex now to the sent pointer and returns TRUE or FALSE.
4016 Affected file lib/silcutil/silcmutex.h.
4018 * Wrote the SILC Task Queue interface to support multi-threads.
4019 Affected file lib/silcutil/silctask.[ch].
4021 * Wrote the SILC Scheduler to support multi-threads. Affected
4022 file lib/silcutil/silcschedule.c.
4024 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4026 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4027 in lib/silcutil/win32/.
4029 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Defined SILC Mutex API and SILC Thread API and implemented
4032 them for Unix. Affected files are
4033 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4034 lib/silcutil/unix/silcunixmutex.c and
4035 lib/silcutil/unix/silcunixthread.c.
4037 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Fixed the silc_server_remove_clients_by_server's channel
4040 key re-generation. The hash table handling was incorrect
4041 and would not work with many channels. Affected file is
4044 * Fixed some memory leaks around the server code.
4046 * Rewrote the silc_server_get_users_on_channel to support IPv6
4047 based Client ID's. Affected file silcd/server.c.
4049 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4050 specification. However, a separate document must be written
4051 to define the detailed signing procedure and the payload
4052 associated with the flag. Defined the flag to the
4053 lib/silccore/silcchannel.h as well.
4055 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4057 * Changed the dynamic tables to static size tables in the
4058 lib/silccrypt/silchmac.c.
4060 * Removed GCC dependencies from the code. A patch by cras.
4062 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Do not show the error "Error receiving packet bla bla"
4065 in server if it really was not an error (-2 means that reading
4066 is pending). Affected file silcd/server.c.
4068 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Fixed a possible crash in silc_server_remove_clients_by_server
4071 in silcd/server.c. Fixed there also some memory leaks.
4073 * Fixed the silc_idlist_replace_client_id. It could replace
4074 wrong key in the hash table. Affected file silcd/idlist.c.
4076 * Do not check whether there are global users on the channel
4077 if the channel->global_users is FALSE. Affected functions
4078 silc_server_remove_from_one_channel and
4079 silc_server_remove_from_channels in silcd/server.c. Also,
4080 do not check if the removed client is local as we can be
4081 sure that global client was not removed from the channel
4082 and checking for global users is not needed.
4084 * The silc_server_remove_clients_by_server now re-generates
4085 the channel keys correctly for those channels that had
4086 clients removed from them. Affected file silcd/server.c.
4088 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4090 * Found the reason of random crashes in the server. We weren't
4091 ignoring the SIGPIPE signal (which can be sent in write())
4092 and it crashed the server. Affected file silcd/silcd.c.
4094 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Assure that sock->user_data is not NULL in the function
4097 silc_server_packet_send in silcd/packet_send.c.
4099 * Disconnect the remote connection if it could not be added
4100 to any ID lists in the server. The affected file is
4103 * Check in silc_server_packet_send[_real/dest] that the
4104 socket is not disconnecting and ignore the data if it is.
4105 Affected file silcd/packet_send.c.
4107 * Define inline to __inline on native WIN32 compilation.
4108 Affected file includes/silcwin32.h.
4110 * Added some explicit type casts for inline code since MSVC
4111 require them. Affected files lib/silcutil/silcbuffer.h,
4112 lib/trq/silcdlist.h and lib/trq/silclist.h.
4114 * Print warning in log files from now on if the packet
4115 decryption fails. Affected file silcd/server.c.
4117 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Changed the `say' client operation's interface to accept
4120 new `type' argument to indicate the type of the message sent
4121 by the library. The application may filter the library's
4122 messages according the type. The affected file is the
4123 lib/silcclient/silcapi.h.
4125 * Added two new functions to lib/silcclient/silcapi.h:
4126 silc_client_del_client and silc_client_del_client_by_id.
4127 Affected file lib/silcclient/idlist.c.
4129 * Moved the clientincludes.h from includes/ to silc/ and
4130 serverincludes.h from includes/ to silcd/.
4132 * The modes for the CMODE and CUMODE are now passed as
4133 uint32 for application with COMMAND_REPLY. The affected
4134 file is lib/silcclient/command_reply.c.
4136 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4138 * /WHOIS without arguments shows client's own information.
4139 Affected file lib/silcclient/command.c.
4141 * Changed PING to not accept any arguments. The specs
4142 says that client can ping only the connected server so
4143 requiring an argument is not needed. Affected file is
4144 lib/silcclient/command.c.
4146 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Fixed a fatal bug in private message sending and reception
4149 encryption and decryption when using private message keys.
4150 The implementation was incorrect and did not follow the
4151 specification. It causd that some of the message were
4152 lost since it did not use the sending and receiving keys
4153 as the protocol suggests. This has been fixed and will cause
4154 incompatibilities with older clients when sending private
4155 message encrypted with private message keys. Affected files
4156 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4157 and various other in Irssi SILC Client.
4159 Added `responder' boolean argument to the functions
4160 silc_client_add_private_message_key[_ske] to indicate when
4161 the key is added as responder or initiator of the key
4164 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4166 * Removed the silc_ske_check_version function and created
4167 a SilcSKECheckVersion callback. Added also a function
4168 silc_ske_set_callbacks that is now used to set all SKE
4169 callbacks. The callback functions are not given to
4170 the SKE functions anymore, but this function is used to
4173 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4175 * Added `silc_version' argument to the silc_client_alloc
4176 to define the version of the application for the library.
4177 The library will use the version string to compare it
4178 against the remote host's (usually a server) version
4179 string. Affected file lib/silcclient/silcapi.h
4181 * Added the KE protocol context to Key Agreement context
4182 in client library so that we can abort the SKE if it
4183 is in process when we get timeout. Affected file is
4184 lib/silcclient/client_keyagr.c.
4186 * Do not resolve the client ID forever if it returns in the
4187 first time that such client does not exist. This was done
4188 for example with private message. Affected file is
4189 lib/silcclient/client_prvmsg.c.
4191 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Do not add regex.h for WIN32. The affected file
4194 includes/silcincludes.h.
4196 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4197 not work yet 100%. It generates the DLL's automatically
4198 when compiling with --with-win32 under cygwin.
4200 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4202 * lib/contrib/regex.c is not compiled on WIN32.
4204 * Added silc_net_get_socket_opt function to the
4205 lib/silcutil/silcnet.h.
4207 * Added includes/silcwin32.h for WIN32 specific includes
4210 * Do not use ptime structure or any of the posix process
4211 functions on WIN32 in lib/silccrypt/silrng.c.
4213 * Added silc_gettimeofday to provide generic function
4214 for struct timeval on all platforms. Added the function
4215 to lib/silcutil/silcutil.h.
4217 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4219 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4220 library as they clearly belong there. As a plus side we
4221 can make the actual socket connection routines platform
4224 Added also new generic function silc_socket_read and
4225 silc_socket_write (that used to be silc_packet_[read/write].
4226 The implementation of these are platform specific.
4228 * Added WIN32 specific routines of silc_socket_[read/write]
4229 to lib/silcutil/win32/silcwin32sockconn.c.
4231 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4233 * Added preliminary support for native WIN32 compilation under
4234 cygwin (using the -mno-cygwin option for GCC) to the
4235 ./configure.in.pre. The --with-win32 now prepares the
4236 compilation for native WIN32.
4238 * Rewrote the SILC Scheduler interface in the file
4239 lib/silcutil/silcschedule.h. The scheduler is now context
4240 based and does not have anymore any global static scheduler.
4241 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4242 and created lib/silcutil/win32 directory for WIN32 based
4245 * Added Unix specific network routines to the
4246 lib/silcutil/unix/silcunixnet.c and the old
4247 lib/silcutil/silcnet.c includes now only generic routines.
4249 Added WIN32 specific network routines to the
4250 lib/silcutil/win32/silcwin32net.c.
4252 * Added Unix specific utility functions from the
4253 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4255 * Added WIN32 SILC Scheduler to the file
4256 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4259 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4261 * Do not handle JOIN notify in the server if the target client
4262 is not registered (idata->registered == FALSE). The affected
4263 file is silcd/packet_receive.c.
4265 * Update the nickrec->founder in event_cumode in the Irssi SILC
4266 client. Affected file irssi/src/silc/core/silc-channels.c.
4268 * Fixed the CUMODE_CHANGE notify handling in the server when
4269 server and router are announcing their clients on channels.
4270 Now the mode changes are saved and notified correctly. The
4271 affected file is /silcd/packet_receive.c.
4273 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4274 They really did not replace the cache entry in the ID Cache.
4275 Now they do that. Affected file silcd/idlist.c.
4277 * Fixed the KICK notify handling in the Irssi SILC client to
4278 update the channel records so that the kicked client does not
4279 appear to be on the channel. The affected file is
4280 irssi/src/silc/core/silc-channels.c.
4282 * Always update the conn->current_channel when executing command
4283 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4285 * Fixed the KILL notify handling in Irssi SILC client to remove
4286 the killed client on all channels.
4288 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Fixed the silc_parse_command_line to remove extra spaces
4291 from the start and end of the arguments. Affected file is
4292 lib/silcutil/silcutil.c.
4294 * Cancel and free any active protocol in the function
4295 silc_server_close_connection. Affected file silcd/server.c.
4297 * Cancel and free any active protocol in the function
4298 silc_client_close_connction. Affected file is
4299 lib/silcclient/client.c.
4301 * Do not execute the KILL command for clients that are in
4302 history (ie. they are not in the network). Affected file is
4305 * Fixed KILL notify handling, client does not crash anymore.
4306 Affected file irssi/src/silc/core/silc-channels.c.
4308 * Reduced the default packet buffer size from 2048 to 1024 in
4309 lib/silccore/silcpacket.c.
4311 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4312 counter to the SKE context that is incresed when the SKE library
4313 performs async operation outside the library. If the outside
4314 process frees the SKE context and FREED status will be set
4315 and the library will detect after the sync operation that the
4316 libary is freed. The affected files are
4317 lib/silcske/silcske[_status].[ch].
4319 * Resolve the client entry information in the function
4320 silc_client_channel_message to assure that NULL pointer is not
4321 passed as client entry to the application. */
4323 * Fixed the task timeout calculation to assure that there is
4324 never negative timeouts. The affected file is
4325 lib/silcutil/silcschedule.c.
4327 * Fixed the channel user mode notification sending in server.
4328 It was sent point-to-point to the router (or to server by router)
4329 but it needs to be destined to a channel. The routines now
4330 supports sending the channel user mode notifys to the channels
4331 when announcing clients and channels. Affected files are
4332 silcd/server.c and silcd/packet_receive.c.
4334 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4335 It did not actually replace the old channel entry in the cache.
4336 Affected file lib/silcclient/client_notify.c.
4338 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Fixed a possible crash in silc_packet_send_prepare. It now
4341 assures always that there is enough space in the buffer and
4342 at the tail area of the buffer (for MAC).
4344 Fixed the inbound buffer reallocation in silc_packet_read.
4345 It was old code and did not handle the reallocation correctly.
4348 The affected file is lib/silccore/silcpacket.c.
4350 * Fixed buffer overflow in silc_parse_nickname in the file
4351 lib/silcutil/silcutil.c.
4353 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * make install generates new server keys only if there is not
4358 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4361 Added check that if the NOREPLY is set then we will not send
4362 the away message. This avoids infinite loop of away messages
4363 if both clients are away. The affected file is
4364 lib/silcclient/client_prvmsg.c.
4366 * Fixed client crash if /NICK was given without arguments.
4367 Affected file lib/silcclient/command.c.
4369 * Server does not send the invite list in INVITE command back
4370 to the client if the list was not altered. Added this notion
4371 to the protocol spec as well. Affected file silcd/command.c.
4373 Fixed possible crash in INVITE command by checking the
4374 value of silc_server_get_client_route command.
4376 * Fixed the INVITE notify type handling. The arguments are now
4377 taken in correct order and client does not crash. The affected
4378 file is irssi/src/silc/core/silc-channels.c.
4380 Removed the "Inviting xxx to channel" message from the
4381 client library away and let the application handle it.
4382 Affected file lib/silcclient/command.c. Added that message
4383 to Irssi SILC client's message formats.
4385 * Fixed CMODE command crash in client. It now checks the
4386 amount of arguments correctly and does not crash. The affected
4387 file is lib/silcclient/command.c.
4389 * Do not create new channel automatically in silc_channels_join
4390 but check whether the channel by that name already exists.
4391 Affected file irssi/silc/core/silc-channels.c.
4393 * Do not send the SERVER_SIGNOFF to router if the disconnected
4394 entity was the router. Affected file silcd/server.c.
4396 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4397 SILC client as it was missing from there.
4399 Added the handling of the KICK notify to the Irssi SILC client
4400 as it was missing. Added "you have been kicked" message to
4401 Irssi SILC client's message modules formats.
4403 Added the handing of the KILL notify to the Irssi SILC client
4404 as it was missing. Added the kill message module formats
4407 The affected file is irssi/src/silc/core/silc-channels.c.
4409 * The router did not save the channel mode the server announced.
4410 Affected file silcd/packet_receive.c.
4412 * Fixed a possible crash in INFO command in server. If the
4413 server did not provide the server info it crashed. Affected
4414 file silcd/command.c.
4416 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Fixed the GETKEY command in the server to check also the
4419 global list. Otherwise the GETKEY would not work correctly
4420 in normal SILC server. Affected file silcd/command.c.
4422 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Fixed GETKEY crash, it crashed if the command did not succseed.
4426 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4429 is now real and not just an macro interface to GMP.
4431 Removed the entire GMP from the source tree and imported new
4432 NSS MPI library instead. Reason for removing GMP is that it is
4433 extremely large and compiles extremely slow. The NSS MPI
4434 is only a few files and compiles in less than 10 seconds.
4435 The speed is also about the same as GMP. The MPI is imported
4436 to lib/silcmath/mpi.
4438 If the system has GMP installed we will still use the GMP.
4439 If it is not then the NSS MPI will be compiled.
4441 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Merged a long nickname (127 characters long) crash bugfix from
4444 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4446 * Merged a freed memory reference bugfix from Irssi CVS tree.
4447 Affected file irssi/src/core/commands.c.
4449 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added the server's public key sving and verification to the
4452 server when performing the SKE. This was missing and the
4453 remote server's (or router's) public key was accepted without
4454 checking whether we have it previously or trust it at all.
4455 Affected file silcd/protocol.c.
4457 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Check in the silc_server_timeout_remote if protocol is active
4460 and make sure that the protocol's final callback is called so
4461 that all memory if freed. Affected file silcd/server.c.
4463 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * silc_server_whois_send_reply crashed the server if the nickname
4466 was 127 characters long. Affected file silcd/command.c.
4468 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added sanity check to the silc_server_new_client. If the hostname
4471 is provided inside username then check that the provided hostname
4472 really is the same as the resolved one. If the hostname was not
4473 resolved then check it from the public key. Affected file is
4474 silcd/packet_receive.c.
4476 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4477 if the server disconnected us and the connection is not valid
4478 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4480 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4481 the library to the lib/silcutil/silcutil.[ch].
4483 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Close log file after open. Affected file
4486 lib/silcutil/silclog.c.
4488 * Check whether sock == NULL in silc_client_send_packet and return
4489 if it is. Affected file lib/silcclient/silcclient.c.
4491 * Check rec->entry == NULL in the Irssi SILC Client before
4492 sending the channel message. Affecte file is
4493 irssi/src/silc/core/silc-servers.c.
4495 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Merged a splitted window bugfix from Irssi CVS tree. The
4498 affected file is irssi/src/fe-text/textbuffer-view.c.
4500 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4501 It did not print nickname.
4503 * Improved the distributions system a bit.
4505 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4508 irssi/src/fe-text/gui-window.c.
4510 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4511 to in-active server. The affected file is
4512 irssi/src/silc/core/client_ops.c.
4514 * Resolve the client in USERS command reply if the entry does
4515 not have username resolved. The affected file is
4516 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4517 command to WHOIS command to really resolve stuff. The USERS
4518 is not used any more in any critical section so WHOIS can
4519 be used even though it might be slower than IDENTIFY.
4521 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4524 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Changed the protocol API a bit more consistent in the
4527 lib/silccore/silcprotocol.[ch].
4529 * Changed the following headers to ROBODoc format:
4531 lib/silccore/silcpayload.h
4532 lib/silccore/silcprotocol.h
4533 lib/silccore/silcsockconn.h
4535 All core library headers are now formatted.
4537 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Fixed a bug in Irssi SILC client; do not show that you are
4540 server/router operator if you really are not. Affected file is
4541 irssi/src/silc/core/client_ops.c.
4543 * Renamed silc_command_free_payload to silc_command_payload_free.
4544 Affected file lib/silccore/silccommand.h
4546 * Added silcmath.h to include the prototoypes of various routines
4547 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4550 * Changed the following headers to ROBODoc format:
4552 lib/silccore/silcchannel.h
4553 lib/silccore/silccommand.h
4554 lib/silccore/silcid.h
4555 lib/silccore/silcidcache.h
4556 lib/silccore/silcmode.h
4557 lib/silccore/silcnotify.h
4558 lib/silccore/silcpacket.h
4559 lib/silcmath/silcmath.h
4561 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added checking to the server code not to start the server if
4564 ciphers and stuff are not configured properly. Affected files
4565 silcd/serverconfig.[h] and silcd/server.c.
4567 * Changed the layout of the header files of the public interfaces
4568 in the SILC libraries. The new layout supports ROBODoc
4569 documentation tool (and some others) so that it is easy to create
4570 a library reference manual. All the other headers and source
4571 code must still follow the CodingStyle document. Also source
4572 code must not include these ROBODoc stuffs, only the headers.
4573 Furthermore, all public interface headers must now be named
4574 by using `silc' prefix, example: silcapi.h, silccipher.h.
4575 Some files were renamed due to this. All the other headers
4576 must not be used as public interfaces. I will update the
4577 CodingStyle document later. Changed following headers, so far:
4579 lib/silcclient/silcapi.h
4580 lib/silccore/silcauth.h
4581 lib/silccore/silcprivate.h
4582 lib/silccrypt/silcdh.h
4584 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Removed silc_client_packet_send_flush from the client library
4589 as it is not needed. Affected file lib/silcclient/client.[ch].
4591 * Added printing of message of unresolved authentication method
4592 to the Irssi SILC client. Added it to the module formats.
4593 Removed the same message from the client library.
4595 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added new distribution feature, DISTLABEL. Every distribution
4598 can define own preprocessor label that can be used in the
4599 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4600 file distributions, acconfig.h.pre and prepare.
4602 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added Makefile.defines_int to include the actual definitions
4605 for Makefile.defines.in. Tested the new distribution system,
4606 created distributions and tested installation.
4608 * Added AWAY message printing to the Irssi SILC client. Added
4609 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4611 * Added SCONNECT command to call the SILC's CONNECT command.
4612 Cannot use CONNECT directly since Irssi uses that internally.
4613 Affected file irssi/src/silc/core/silc-servers.c.
4615 Added ACTION local command. It is same as ME command but takes
4616 the channel as mandatory argument.
4618 Rewrote some of the Irssi's help files to suite for SILC
4621 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Added Makefile.defines[.in] that should for now on be included
4624 in all Makefile.am file in the source tree. That file includes
4625 all common compilation definitions for SILC source tree.
4627 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Minor changes to the ./prepare script to change the package
4630 name according the distribution name to the configure.in.
4632 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Created new distribution system. Added file `distributions'
4635 that defines all the distributions that can be created out of
4636 the SILC source tree. The ./prepare script now reads that
4637 file to determine how to prepare the distributions. The
4638 first argument to the ./prepare is the name of the distribution
4639 and second is the version of the distribution. If given
4640 without arguments it creates the default (toolkit) distribution
4641 with the default version (defined in ./prepare).
4643 All Makefile.am files that are subject to the distributions
4644 are now named as Makefile.am.pre. These are ./Makefile.am
4645 and lib/Makefile.am. Others may be changed later.
4647 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added invite list, ban list, some key management and connection
4650 error message printing to module formats in the Irssi SILC client.
4652 * Added new silc_client_set_away_message to set the away message
4653 that is back to the person who sent private message. The
4654 affected file lib/silcclient/silcapi.h and the
4655 lib/silcclient/client_prvmsg.c.
4657 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Fixed the private message sending in the Irssi SILC client,
4660 added local command KEY to the Irssi SILC client.
4662 Added key management and key agreement message formats to the
4663 irssi/src/fe-common/silc/module-formats.[ch].
4665 Added USERS (alias WHO) printing, server/router operator
4666 indication and LIST command printing to the module formats.
4668 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Fixed channel joining notify handling, cumode notify handling
4671 from Irssi SILC client.
4673 * Added SILC specific module-formats to the Irssi SILC client so
4674 that SILC specific message hilighting, colors etc is possible.
4675 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4677 Added channel mode, channel user mode, actions, notices,
4678 whois and whowas printing to the the module-formats.c.
4680 * Fixed a bug in channel deletion in the server. The channel
4681 is not left to the cache even if the channel founder auth mode
4682 is set when there are no users anymore on the channel. Affected
4683 file silcd/server.c.
4685 * The silc_net_localhost now resolves the entire hostname including
4686 the domain name. Affected file lib/silcutil/silcnet.c.
4688 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Changed the ask_passphrase client operation to be ascynchronous.
4691 It has now a completion callback and a context that the
4692 application must call after it has got the passphrase from
4693 the user. Affected files lib/silcclient/silcapi.h,
4694 lib/silcclient/protocol.c, lib/silcclient/command.c and
4697 Added SilcAskPassphrase callback that the application calls
4698 to deliver the passphrase to the library.
4700 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4701 The public key verification and especially a certificate
4702 verification is asynchronous procedure.
4704 Added new SILC_SKE_STATUS_PENDING status to indicate the
4705 request is pending and a callback will be called to finalize
4708 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4709 indicate that remote end did not send its public key (or
4710 certificate), even though we require it. Added check for this
4711 condition in the SKE. This was a security bug, now fixed.
4713 Defined new SilcSKEVerifyCbCompletion callback that is called
4714 when the verification process is completed.
4716 The affected files lib/silcske/silcske_status.h and
4717 lib/silcske/silcske.[ch].
4719 * Changed the verify_public_key client operation to be async
4720 as well. Defined SilcVerifyPublicKey callback that is used to
4721 indicate the success of the public key verification process.
4723 Changed the server and client to use the new async client
4726 * Changed the Irssi SILC client's internal scheduler to be called
4727 twice as many times as it used to be. As a result the client
4728 should be a bit faster now. Affected file is
4729 irssi/src/silc/core/silc-core.c.
4731 * Added support to Irssi SILC client of asynchronous public key
4732 verification and passphrase inquiry. Affected file is
4733 irssi/src/silc/core/silc-core.c.
4735 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Do not say "You have left channel %s" in client library.
4738 Moved it to the application. Affected files are
4739 lib/silcclient/command.c and silc/client_ops.c.
4741 * Fixed silc_client_get_clients. Command context was not
4742 duplicated and was freed memory in the callback. Affected
4743 file lib/silcclient/idlist.c.
4745 * Do not say "you are now talking..." on JOIN command in the
4746 client library. The appliation must handle it.
4748 * Do not say ".. changed topic to" in command reply in the
4749 client libary. The application must handle it.
4751 * Fixed TOPIC command sending in the client library.
4753 * Fixed a memory leak in silc_client_command_free in the file
4754 lib/silcclient/command.c.
4756 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Imported a modified version of Irssi client to the source tree.
4759 The Irssi will be used to create a new client called
4760 Irssi SILC. Imported to irssi/.
4762 Added silc_core_init_finish function to the Irssi. Affected
4763 file irssi/configure.in.
4765 A lot changes in the Makefile.ams around the irssi tree.
4767 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Do not rehash if the new size is same as the old size of the
4770 hash table, in the silc_hash_table_rehash*. The affected file
4771 lib/silcutil/silchashtable.c.
4773 * Replaced hash_table_del_by_context calls from the server
4774 (when channel->user_list and client->channels) to the
4775 hash_table_del as it is sufficient and faster.
4777 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added silc_hash_table_list, silc_hash_table_get and the
4780 SilcHashTableList structure to provide an alternative way to
4781 traverse the hash table. The affected files are
4782 lib/silcutil/silchashtable.[ch].
4784 * Changed the server's idlist routines to use the hash table
4785 routines to optimize the code.
4787 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Replaced the client entry's `channel' list and channel entry's
4790 `user_list' list to hash tables for optimized lookup. Changed
4791 the code to use the hash table interface around the code.
4792 Affected file lib/silcd/idlist.[ch].
4794 * Added `auto_rehash' boolean argument to the function
4795 silc_hash_table_alloc to indicate whether the hash table should
4796 auto-rehash when it thinks is appropriate time. It will
4797 increase the hash table size if the there is twice as much
4798 entries in the table than the size of the table, and will
4799 decrease the size if there are twice as less entries than
4800 the size of the table.
4802 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4806 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * silc_idcache_purge_by_context deletes the entry now by context
4809 as it is supposed to do. Affected file lib/silccore/idcache.c.
4811 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4812 client is not anymore valid (WHOWAS givens the info) and not
4813 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4815 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Removed the `data' and `data_len' arguments from the ID Cache
4818 interfaces and added `name' argument. ID Cache does not handle
4819 anymore the binary data only a names associated with given ID.
4821 * When hashing a Client ID with silc_hash_id the entire ID is
4822 not hashed anymore, instead only the hash of the Client ID is
4823 hashed. This way we can access the Client ID from the cache
4824 with Client ID but with the hash of the ID (which is a hash of
4825 the nickname) as well without any difference in performance.
4827 Added also silc_idcache_find_by_id_one_ext to do one on one
4828 searching when we have the actual ID. Added also function
4829 silc_hash_client_id_compare. The affected files are
4830 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4832 * When hashing the name associated with a ID it is always done
4833 in lowercase. This way we can access the cache without worrying
4834 about case-sensitivity, even though, for example nicknames are
4837 * Fixed a bug in server with channel message sending. It put
4838 wrong ID type as destination ID. The affected file
4839 silcd/packet_send.c.
4841 * silc_idcache_del_by_context now deletes from all hash tables
4842 by context. Affected file lib/silccore/idcache.c.
4844 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Changed the client library to use the new ID Cache interface.
4847 Changes around the source tree.
4849 * Added silc_hash_table_rehash_ext to rehash with specific
4850 hash function. Affected file lib/silcutil/silchashtable.[ch].
4852 * Added silc_hash_string_compare to compare two strings in the
4853 hash table. Affected file lib/silcutil/silcutil.[ch].
4855 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Added new function silc_idcache_del_by_context into the
4858 lib/silccore/idcache.[ch].
4860 * Changed the server's ID list routines to use the new ID Cache
4861 interface. Changes around the source tree.
4863 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Added silc_hash_table_del[_by_context]_ext functions in to the
4866 lib/silcutil/silchashtable.[ch].
4868 Removed silc_hash_table_find_all* routines and added new
4869 silc_hash_table_find_foreach to replace them.
4871 Added silc_hash_table_replace_ext function as extended
4872 replacing function. Separated the simple hash table interface
4873 from the extended hash table interface in the file
4874 lib/silcutil/silchashtable.h.
4876 * Fixed minor bugs and changed it to use some of the new
4877 hash table functions in lib/silccore/idcache.c
4879 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Added new function silc_hash_table_find_all to return all keys
4882 in the hash table by the specified key. As the hash table is
4883 collision resistant it also makes it possible to have several
4884 duplicate keys in the hash table. This function may be used to
4885 find all of the keys from the hash.
4887 Added user_context arguments to the SilcHashFunction,
4888 SilcHashCompare and SilcHashDestructor to deliver user specified
4891 Added new fuctions silc_hash_table_find[_all]_ext to do
4892 extended lookup with specified hash and compare functions and
4893 specified user contexts.
4895 Added new function silc_hash_table_add_ext to add the key
4896 with specified hash function and user context.
4898 Added new function silc_hash_table_foreach to traverse all
4899 entrys in the hash table. Added SilcHashForeach callback
4902 Added new function silc_hash_table_del_by_context to delete
4903 the entry only if the context associated with the key matches.
4905 Affected files are lib/silcutil/silchashtable.[ch].
4907 * Removed silc_hash_[server/client/channel]_id and added just
4908 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4909 silc_hash_id_compare to compare two ID's using as the hash table
4910 comparison function. Added also silc_hash_data to hash
4911 binary data and silc_hash_data_compare to compare it.
4913 * Removed silc_idlist_find_client_by_hash as it is not needed
4914 anymore. Affected file silcd/idlist.[ch].
4916 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4917 to use internally the SilcHashTable. The new ID Cache is a lot
4918 faster than the old one. Some of the ID Cache interface was also
4919 rewritten and obsolete and stupid functions were removed.
4921 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added entry_count field to the SilcHashTable to keep the number
4924 of the entries in the table. Implemented the function
4925 silc_hash_table_rehash. Added new function
4926 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4928 Fixed a minor bug in silc_hash_table_free.
4930 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4931 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4932 into the lib/silcutil/silcutil.[ch].
4934 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Implemented a collision resistant hash table into the
4937 lib/silcutil/silchashtable[ch]. See the header and the source
4938 for the SilcHashTable API.
4940 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Merged dotconf version 1.0.2 into lib/dotconf.
4944 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Do not compile anything in lib/silcsim/* if the SIM support
4947 is not enabled. The tree should now compile without problems
4950 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Compiled the SILC under cygwin. Compiled and tested briefly
4953 without problems. More tests needed. The SIMs didn't compile
4956 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4958 * Fixed possible crash in silc_get_username in the
4959 lib/silcutil/silcutil.c.
4961 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Fixed a va_arg in silc/client_ops.c.
4965 * Oops, RC5 routines were named AES and caused some problems
4966 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4968 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Added new SilcIDIP structure into the lib/silccore/id.h and
4971 replaced the old `ip' fields from all SILC ID's to that type.
4972 This is a step towards IPv6 support.
4974 The silc_id_get_len takes now the ID as an extra argument.
4975 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4976 both IPv4 and IPv6 based ID's.
4978 The affected files are lib/silccore/id.[ch] and other files
4979 around the tree using these routines.
4981 * Removed the ID length arguments in server from various
4982 silc_server_send_notify_* routines -> they are not needed
4985 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed memory leak in silc_encode_pem_file in the file
4988 lib/silcutil/silcutil.c.
4990 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Check minor version as well in the SKE. Affected files are
4993 silcd/protocol.c and lib/silcclient/protocol.c.
4995 * Added --identifier option to the server so that an identifier
4996 can be when creating the public key for the server. Affected
4997 file is silcd/silcd.c.
4999 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5000 lib/silccrypt/silcpkcs.c.
5002 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Register default ciphers and stuff when using -C option with
5005 the server. Affected file sildc/silcd.c.
5007 * Put back the servers public key filename format, it is better
5008 than the new one. For now, the client keys are saved with the
5009 new filename format. The affected file silc/client_ops.c.
5011 * Implemented the Cipher API for the rest of the ciphers that
5012 did not implement it or implemented it the wrong way.
5014 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Register default ciphers and stuff when using the -S option
5017 in the client. Affected file silc/silc.c. Same also when
5018 creating new key pair with -C option.
5020 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Fixed the silc_verify_public_key client operation function to
5023 save the public keys differently. The fingerprint is now
5024 used as filename and not the hostname. This way also the
5025 client keys are saved uniquely and not with hostnames. The
5026 affected file is silc/client_ops.c.
5028 * Trimmed the silc_hash_fingerprint function to remove extra
5029 whitespaces from the end of the fingerprint. The affected
5030 file is lib/silccrypt/silchash.c.
5034 * Added silc_cipher_register_default function to register all
5035 default ciphers. It can be used when configuration files
5036 does not exist and the application does not want any specific
5037 ciphers in any specific order.
5039 The SilcDList is now used as silc_cipher_list dynamically
5040 allocated cipher list. Removed the static list all together
5041 and now all ciphers must be allocated to the dynamic list.
5042 The silc_cipher_alloc routine was changed to check only the
5045 All silc_cipher_* routines that used to return int returns
5048 The affected files lib/silccrypt/silccrypt.[ch].
5050 * The same thing was done to silc_hash_* as for silc_cipher_*
5051 routines. Affected files lib/silccrypt/silchash.[ch].
5053 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5054 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5055 Added also silc_pkcs_[un]register[_default] functions.
5056 Removed the data_context from the PKCS API.
5058 * Added silc_hmac_register_default function to register default
5059 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5060 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5061 to unregister all hmacs at once.
5063 * Register the default ciphers, hash functions, PKCSs and HMACs
5064 if client's configuration file does not exist. The affected
5067 * The client did not load the hash functions from the SIM
5068 modules at all. Added support for this. Affected file is
5069 silc/clientconfig.c.
5071 * When decoding public key with silc_pkcs_public_key_decode, check
5072 the supported algorithm only if PKCS are registered. Affected
5073 file lib/silccrypt/silcpkcs.c. The same was done with the
5074 silc_pkcs_private_key_decode.
5076 * Fixed the SILC List routines to keep the list always in order.
5077 It used to change the list's order when traversing the list but
5078 not it preserves the order. Affected file lib/trq/silclist.h.
5080 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Added the client library to use the SilcSocketConnection's
5083 reference counter (by silc_socket_dup) to prevent the bug that
5084 the socket object may be freed underneath async operation.
5086 * The name resolv library checking fixes in the configure.in.pre.
5089 * Created new version of the protocol drafts for future
5090 development. The -03 drafts are the ones that will be changed
5091 in the trunk now and the -02 will remain as they are.
5093 * Send list of CUMODE notifys to the router when announcing
5094 the channel users to the router. Affected file silcd/server.c.
5095 If the router receiving channel founder CUMODE for a channel
5096 that already has channel founder it will send CUMODE notify
5097 to the sender to remove the channel founder rights from the
5098 announced client. Affected file silcd/packet_receive.c.
5100 * The CUMODE notify may now use Server ID as well as the entity
5101 who changes the mode. Updated protocool specs.
5103 * Updated INSTALL and README files.
5105 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * New web pages in the http://silc.pspt.fi. The pages was
5112 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Implemented the [DenyConnectin] config section in the server.
5115 Added silc_server_config_denied_conn to check whether incoming
5116 connection is denied. Affected file silcd/serverconfig.[ch].
5118 * Do not check the ports when checking the incoming configuration
5119 data if the port is 0, meaning any. Affected file is
5120 silcd/serverconfig.c.
5122 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Fixed buffer overflow in silc_string_compare in the file
5125 lib/silcutil/silcutil.c.
5127 * Fixed double free in silc_server_command_leave in the file
5130 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Fixed the version checking in the server. Affected file is
5135 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Fixed the configuration data fetching when accepting new
5138 connections in the server. Affected file silcd/server.c.
5140 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Added `sender_entry' argument to the function
5143 silc_server_packet_relay_to_channel so that we can check
5144 whether some destination actually belongs to the same route
5145 the sender belongs (ie, we must not resend the packet to the
5146 sender). Affected file silcd/packet_send.[ch].
5148 * Added `servername' field to the SilcClientEntry in the server
5149 to hold the name of the server where client is from. Affected
5150 file is silcd/idlist.h.
5152 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Moved the channel message encrypting in the router betwen
5155 router connections from silc_server_channel_message to the
5156 silc_server_packet_relay_to_channel since we want to check
5157 whether we have anybody channel before encrypting anything.
5158 Affected files silcd/packet_[receive/send].c.
5160 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Fixed the [AdminConnection] server config section to support
5163 multiple entries. Affected file silcd/serverconfig.c.
5165 * Added support into the server to check the validity of the
5166 incoming connection before executing any KE or authentication
5169 * The connection configuration is now saved to the KE and
5170 connection auth protocol contexts and not fetched anymore in
5171 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5173 * The local hosts listenning address and port is also resolved
5174 now when starting the server. We want to have the socket object
5175 to include the real address and port for the listener. Added
5176 new function silc_net_check_local_by_sock into the files
5177 lib/silcutil/silcnet.[ch].
5179 * Fixed a broadcast bug in server -> do not broadcast if we
5182 * Fixed a routing bug. Do not route broadcast packets ever.
5183 Broadcast packets must be processed always and not routed since
5184 they may be destined to some other host than yourself and thus
5185 would get routed without no good reason. Affected file is
5188 * Added function silc_server_config_is_primary_route to check
5189 whether primary router connection has been configured (a router
5190 configuration that we are initiating). If there is not, we
5191 will assume that there is only two routers in the SILC network
5192 and we will use the incoming router connection as our primary
5193 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5195 * Changed the order of the broadcasting. Broadcast _after_ the
5196 packet has been processed not before. Affected file is
5199 * Fixed a [ClientConnection] parsing bug. The port was never
5200 parsed correctly thus resulting to port 0. Affected file
5201 silcd/serverconfig.c.
5203 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5204 argument and did not set the broadcast packet flag. Affected
5205 file silcd/packet_send.c. Fixed same bug in the function
5206 silc_server_send_notify as well.
5208 * If we receive NEW_ID packet for our own ID in the server, ignore
5211 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Removed the nickname from the Private Message Payload.
5216 Updated the code and the protocol specs.
5218 * Updated protocol specs for submitting to the IETF.
5220 * Tweaked the Random Number Generator a bit. Affected file
5221 lib/silccrypt/silcrng.c. Exported a new function
5222 silc_rng_[global]_add_noise which can be used to add more
5225 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Do not parse packets with different timeout when protocol
5228 is active -> may cause problem with rekey. Affected file
5231 * When server receives signoff notify it must not create
5232 new channel key if the client is on any channels since the
5233 sender of the signoff notify will create it.
5235 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5237 * Added printing of error messages during SKE protocol from the
5238 failure packet sent by server during SKE. Affected file
5241 * Removed the client's failure_callback handling with timeout
5242 and handle it immediately when received.
5244 * The SKE library returned wrong type in SUCCESS and FAILURE
5245 packets. They must be 32 bit MSB not 16 bit MSB.
5247 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Ok, rewrote the logic of the re-key and now it seems to work.
5250 I tested it on high traffic with frequent re-keys without
5251 problems. Added hmac_receive (and renamed hmac to hmac_send)
5252 in SilcClientConnection in lib/silcclient/client.h and
5253 in SilcIDListData in silcd/idlist.h. Also, removed the
5254 SilcPacketParserContext's cipher and hmac fields as they are
5255 not needed anymore and actually caused some problems when
5256 the ciphers and hmac's changed underneath the packet parser.
5258 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * If re-key protocol is active then process the incoming packets
5261 synchronously since we must assure that icoming packets encrypted
5262 with the old key is processed before the new keys is set to
5263 use. This is true other packets than for REKEY packets.
5264 Affected file silcd/server.c. The same was done to client library
5265 as well, affected file lib/silcclient/client.c.
5267 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Fixed bug in client and server to accept the force send if
5270 the packet is send from silc_[server/client]_packet_process
5271 function. Otherwise the packets are never delivered, oops.
5273 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Disable force sending of packets when REKEY protocol is active.
5276 We must assure that no packet is sent directly when rekey is
5277 performed. All packets must be sent through packet queue.
5278 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5279 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5280 function is silc_[server/client]_packet_send_real to check
5283 * Replaced the SIM paths from example config files to
5284 /usr/local/modules. Also, make install creates now
5285 /usr/local/silc/logs directory to hold all the SILC server
5288 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Made the configure.in.pre work on Solaris. Patch by salo.
5292 * Made all ciphers compatible with non-x86 machines. Defined
5293 CBC mode macros into lib/silccrypt/ciphers_def.h.
5295 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Fixed the make install.
5299 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * When MAC computation fails the silc_packet_decrypt returned 0
5302 even though it was supposed to return -1. Fixed this. The
5303 affected file is lib/silccore/silcpacket.c.
5305 * Do not replace the config files in /etc/silc (in make install)
5306 if they already exist. Affected file ./Makefile.am.
5308 * Do not send re-key packets immediately but through packet queue.
5309 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5311 * Changed silc_net_check_host_by_sock to return FALSE if the
5312 IP/DNS could not be resolved. Though, it returns the IP address
5313 now even if it could not resolve it (but returns also FALSE).
5314 Affected file lib/silcutil/silcnet.[ch].
5316 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Added silc_pkcs_decode_identifier to decode the public key's
5319 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5320 Added also silc_pkcs_free_identifier. Added also new context
5321 SilcPublicKeyIdentifier.
5323 * Added -S option to the silc client. It is used to dump the
5324 contents of the specified public key file.
5326 * Changed the PKCS api to return the public key length when
5327 setting the public key.
5329 * Fixed a fatal bug in the public and private key file loading.
5330 Affected file lib/silccrypt/silcpkcs.c.
5332 * Execute the packet parsing for client with zero (0) timeout
5333 if the protocol is active. Affected file silcd/server.c.
5335 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Made the key generation options to the silcd program. Added
5338 -C option, equivalent to client's option.
5340 * Added new [ServerKeys] config section to the server. It
5341 configures the server's public and private key.
5343 * Defined generic Public Key Payload into the protocol
5344 specification to send specific type of public keys and
5347 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5348 public key or certificate.
5350 * Implemented the GETKEY command to the server and to the
5351 client library and on user interface.
5353 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Made preliminary `make install' work.
5357 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Added SilcServerRekey context into silcd/idlist.h.
5361 * Added the PFS support as defined in the specification to the
5362 SKE protocol. Affected files lib/silcske/*.c.
5364 * Added `ske_group' field to the SilcServerRekey context to hold
5365 the number of the SKE group that is used with PFS in re-key.
5366 Affected file silcd/idlist.h.
5368 * Added PFS re-key support to the server. Affected file is
5371 * Added silc_protocol_cancel to cancel execution of the next
5372 state of the protocol. Affected file is
5373 lib/silccore/silcprotocol.[ch].
5375 * Added the re-key support with and without PFS to the client
5376 library. Re-key is performed once in an hour, by default.
5378 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5379 Added silc_client_rekey_callback and silc_client_rekey_final.
5380 Affected files are lib/silcclient/protocol.[ch] and
5381 lib/silcclient/client.[ch].
5383 * Removed the `hmac_key' and `hmac_key_len' fields from the
5384 SilcClientConnection structure; not needed. Affected file is
5385 lib/silcclient/client.h.
5389 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Do not ask whether user wants to use the negotiated private key
5392 for private messages, just use it. Affected file is
5393 silc/local_command.c.
5395 * Added `send_enc_key' and `enc_key_len' fields to the
5396 SilcIDListData structure since they are needed in the re-key
5397 phase. Affected file is silcd/idlist.[ch].
5399 * Implemented the simple re-key protocol into the server.
5400 Affected files silcd/server.c and silcd/protocol.[ch]. The
5401 re-key will be performed once in an hour, by default.
5403 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5404 Added silc_server_rekey, silc_server_rekey_callback and
5405 silc_server_rekey_final.
5407 * Removed Tunneled flag from the protocol. Updated the code
5408 and the specifications.
5410 * Adde `pfs' field to the SilcIDListData to indicate whether
5411 the PFS is to be performed in the re-key. Affected file is
5414 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5417 int64 of at least the xintXX size. If void * is less that 4
5418 bytes uint32 * will be used. Defined bool as boolean.
5420 * Changed _ALL_ unsigned long and unsigned int to uint32,
5421 unsgined short to uint16 in the source tree.
5423 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5424 not handle clients that has entry->data.registered == FALSE.
5425 They are not in the network anymore. Affected file is
5428 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Implemented the sending of the SERVER_SIGNOFF notify in the
5431 server. Affected file is silcd/server.c.
5433 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5434 Added also silc_notify_payload_encode_args into the
5435 lib/silccore/silcnotify.[ch].
5437 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5438 Affected file silcd/packet_receive.c.
5440 * Implemented the SERVER_SIGNOFF notify handling in the client
5441 library. Affected file lib/silcclient/client_notify.c. Also,
5442 implemnted the printing of the SERVER_SIGNOFF info to the
5443 application. Affected file silc/client_ops.c.
5445 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5446 if the deleting was successful. Affected file silcd/idlist.[ch].
5448 * Added support for public key authentication in the connection
5449 authentication protocol in the client library. Affected file
5450 lib/silcclient/protocol.c.
5452 * Changed the server's silc_idlist_get_clients_by_* interface
5453 to support already allocated array so that new entries may be
5454 added to pre-allocated array. Affected file silcd/idlist.[ch].
5455 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5456 and command replies.
5458 * All command reply functions in the server now calls the
5459 pending command callback even if error occured. This way the
5460 error will be delivered to the client as well. Affected files
5461 silcd/command.c and silcd/command_reply.c.
5463 * Fixed INFO command to return local server's info if no server
5464 was provided. Affected file lib/silcclient/command.c.
5466 * Removed RESTART command for good. Updated the code and the
5469 * Rewrote parts of the task system. It is a bit simpler now.
5470 Removed unsued task priorities. The affected files are
5471 lib/silcutil/silctask.[ch].
5473 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Moved the USERS printing from the library to the application.
5476 Affected files lib/silcclient/command.c and silc/client_ops.c.
5478 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added channel key re-key support. The re-key is perfomed
5483 only by the router and is done once in an hour. Added `rekey'
5484 field to the SilcChannelEntry in the server. Affected files
5485 silcd/server.c and silcd/idlist.h.
5487 * Added silc_task_unregister_by_context into the file
5488 lib/silcutil/silctask.[ch].
5490 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Added SILC_UMODE_GONE mode to indicate when the client is not
5493 present in the SILC network. Added also support to the local
5494 command AWAY that will set this mode. Added support of showing
5495 "xxx is gone" in WHOIS command. The USERS command shows the
5496 gone status as well.
5498 * Fixed setting server and router operator privileges in the
5499 server's UMODE command. Affected file silcd/command.c.
5501 * Merged the SKE KE1 and KE2 payloads into one payload. The
5502 new KE payload is equivalent to the old KE2 payload.
5504 Cleaned up the SKE Start Payload parsing. It now uses the
5505 simple buffer unformatting to do the parsing. A lot faster
5508 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5509 to the SKE that is used to indicate whether both of the SKE
5510 parties should perform authentication. By default only the
5511 responder performs authentication. By setting this flag also
5512 the initiator must do authentication. By default it is unset
5513 since in normal SKE case, client to server connection, only
5514 the responder should do authentication. When doing SKE between
5515 two clients both should perform authentication. Updated the
5516 code and the protocol specs.
5518 * A little fix to IDENTIFY command in the server. Search the
5519 client first by hash not nickname. Affected file is
5522 * Fixed the silc_client_close_connection to support closing
5523 the client to client connections wihtout deleting too much
5524 data. Affected file lib/silcclient/client.c.
5526 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5527 are received if protocol used to be active but is not anymore
5528 the application would crash due to NULL pointer dereference.
5529 Affected files silcd/server.c and lib/silcclient/client.c.
5531 * Added `hash' field to the SilcClientConnection to include
5532 the hash function negotiated in the SKE protocol.
5534 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5535 to set the channel founder authentication data. A client can
5536 claim the founder rights later by providing the authentication
5537 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5538 This way the channel founder can regain the channel founder
5539 privileges even it is left the channel. This works only on
5540 local server and the client must be connected to the same
5541 server to be able to regain the founder rights. Updated the
5542 protocol specs accordingly.
5544 Added support to the CMODE command in the client to set the
5545 founder auth data. Read the README to see how to set it.
5547 Added support to the CUMODE command to claim the founder
5548 rights. Read the README to see how to do it.
5550 Added support for the founder authentication to the Channel
5551 Entry in the server. Affected file silcd/idlist.h.
5553 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5554 server's CMODE command. Affected file silcd/command.c.
5556 * Added the following new functions into lib/silccore/silcauth.[ch]:
5557 silc_auth_get_method and silc_auth_get_data.
5559 * The server now saves the remote hosts public key to the
5560 SilcIDListData pointer. Affected file silcd/protocol.c.
5562 * The normal server now does not remove the channel entry from
5563 the cache if the founder authentication data is set. It used
5564 to remove it if the founder was the last one on the channel on
5565 the server and left the channel. The auth data is saved and
5566 if the channel is re-joined later the old entry is used with
5567 the old auth data. Affected files silcd/command_reply.c and
5570 * Removed the `pkcs' field from the SilcIDListData structure
5571 in the server; it is not used. Affected file silcd/idlist.h.
5573 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Fixed packet processing on slow links. Partial packets were
5576 never re-processed because the incoming data buffer was cleared
5577 by the application. Application must not directly clear the
5578 sock->inbuf, the packet processing routines handle it. Fixed
5579 this in client library and in server.
5581 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Fixed the WHOIS and IDENTIFY send reply function to really
5584 check whether to send list or just one entry. Affected file
5587 * Cleaned up the LEAVE command's channel key distribution. The
5588 affected file silcd/command.c.
5590 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5591 can enforce the channel mode as well. In that case the ID
5592 includes the ID of the server. The code now enforces the
5593 mode change if the router have different mode than the server.
5595 * The notify client operation with CMODE_CHANGE notify can now
5596 return NULL client_entry pointer if the CMODE was not changed
5597 by client. Application must check for this.
5599 * Added <Server ID> argument to INFO command to support server
5600 info fetching by Server ID.
5602 * Added silc_server_announce_get_channel_users to get assembled
5603 packets of channel users of the specified channel. Affected
5604 file silcd/server.[ch].
5606 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5607 was freed underneath the ID Cache.
5609 * Re-announce clients when the server received CHANNEL_CHANGE
5610 notify from the router. Affected file silcd/packet_send.c.
5612 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5615 crashed since it did not handle the fact that there is no cipher
5616 called "3" and didn't check the error condition. Now fixed.
5618 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5619 flag. It can be used to send message requests.
5621 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Implemented the RESTART command in the client.
5625 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5626 notice type messages. Added notice printing to the user
5629 * The channel keys are not re-generated if the channel's mode
5630 is PRIVKEY, ie private key on the channel exists. Affected
5631 files silcd/server.c and silcd/command.c.
5633 * Fixed a little bug in channel message delivery when channel
5634 private keys are set in the server. Affected file is
5635 silcd/packet_send.c.
5637 * Changed the setting on channel->on_channel = TRUE from the
5638 silc_client_save_channel_key to the JOIN command reply. The
5639 key payload is not received if the private channel key is set.
5640 Affected file lib/silcclient/command_reply.c and the
5641 lib/silcclient/client_channel.c.
5643 * When the CMODE_CHANGE notify is sent and the channel private
5644 key mode is removed the channel key must be re-generated in
5645 other cells as well. Added this support for the router in the
5646 silcd/packet_receive.c.
5648 * Added new local command NOTICE to send notice message on
5649 channel. Affected file silc/local_command.[ch].
5651 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Added new local command ME to the client. It is used to send
5654 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5655 some action. Affected file silc/local_command.[ch].
5657 * Changed channel_message and private_message client operations
5658 to deliver the message flags to the application. Added also
5659 the `flags' arguments to the silc_client_send_channel_message
5660 and silc_client_send_private_message functions. Affected file
5663 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Redefined the Private Message Payload to support private message
5666 keys and to support the new private message flags. Updated
5667 the protocol specs. Flags makes it possible to have for example
5668 CTCP style messages.
5670 * Added new type SilcPrivateMessagePayload and defined an API
5671 for it in the lib/silcclient/silcprivate.[ch].
5673 * Tested private message private keys successfully. Tested the
5674 private message key set, unset and list commands with the new
5677 * Redefined the Channel Message Payload to include the channel
5678 message flags (equal with private message flags) to support
5679 for example CTCP style messages.
5681 * Defined some of the message (for channel and private message)
5682 flags. Updated the protocol specs and added the flags to the
5683 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5685 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added SilcKeyAgreementStatus type to the key agreement routines
5688 to indicate the current status and error if one occured.
5689 The status types are defined in the lib/silcclient/silcapi.h.
5691 * Added new local command KEY that is used to set and unset private
5692 keys for channels, set and unset private keys for private messages
5693 with remote clients and to send key agreement requests and
5694 negotiate the key agreement protocol with remote client. The
5695 key agreement is supported only to negotiate private message keys,
5696 it currently cannot be used to negotiate private keys for channels,
5697 as it is not convenient for that purpose.
5699 * Fixed a minor pending callback setting bug in the function
5700 silc_client_get_client_by_id_resolve, now the function works.
5701 Affected file lib/silcclient/idlist.c.
5703 * Added function silc_net_get_local_port to get local bound
5704 port by socket. Added to lib/silcutil/silcnet.[ch].
5706 * Added `sockets' and `sockets_count' fields to the SilcClient
5707 object. They hold the sockets of the listenning sockets in
5708 the client. Listenning sockets may be for example the key
5709 agreement server. Affected file lib/silcclient/client.[ch].
5710 Added functions the silc_client_add_socket and the
5711 silc_client_del_socket. They are exported to the application
5714 * Added ~./silc/clientkeys to support other client's public keys.
5716 * Renamed verify_server_key client operation to verify_public_key
5717 and added one argument to indicate the type of the connection
5718 (server, client etc.).
5720 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added silc_server_connection_auth_request to handle the
5723 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5724 silcd/packet_receive.[ch].
5726 * Added silc_server_send_connection_auth_request into the
5727 silcd/packet_send.c to send the connection auth request packet.
5729 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5732 * Fixed the public key authentication in responder side in the
5733 server. The `auth_data' pointer includes the SilcPublicKey
5734 not the path to the public key. Affected file silcd/protocol.c.
5736 * Implemented the public key authentication in the initiator side
5737 in the server. Affected file silcd/protocol.c.
5739 * Removed the [RedirectClient] config section from the server
5740 configuration. Is not needed and I don't want to implement it.
5742 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Cleaned up the CMODE command in the server. It now works
5745 correctly and supports all the modes defined in the protocol.
5746 Affected file is silcd/command.c.
5748 * Added `hmac_name' field to the SilcChannelEntry in the server
5749 to hold the default HMAC of the channel. It can be set when
5750 creating the channel (with JOIN command). Affected files
5753 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5754 type to indicate the change of the current cipher and hmac
5755 on the channel. Client can safely ignore the <cipher> argument
5756 (if it chooses to do so) since the CHANNEL_KEY packet will
5757 force the channel key change anyway. The <hmac> argument is
5758 important since the client is responsible of setting the new
5759 HMAC and the hmac key into use.
5761 * Fixed the CMODE command in the client library as well.
5763 * Tested CMODE command in router environment successfully.
5765 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Show the version of the remote client (or server) when connecting
5768 to the server. It is logged to the log file. Affected file
5769 is silcd/protocol.c.
5771 * Fixed the KILLED notify handling in the client library. The
5772 client must be removed from all channels when receiving the
5775 Also, do not remove the client entry when giving the KILL
5776 command but when the KILLED notify is received.
5778 * Removed silc_idlist_find_client_by_nickname from the server.
5779 Not needed anymore. Affected files silcd/idlist.[ch].
5781 * Implemented the CHANNEL_CHANGE notify type handling to the
5782 server. Affected file silcd/server.c.
5786 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5800 * Added function silc_server_get_client_resolve to find the
5801 client entry by ID from all ID lists and then resolve it
5802 (using WHOIS) if it cannot be found. Affected file is
5805 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Implemented the BAN command to the client library.
5809 * The JOIN command in the server now checks the invite list
5812 * Changed the silc_command_reply_payload_encode_va and the
5813 silc_command_payload_encode_va to support that if argument is
5814 NULL it ignores and checks the next argument. Affected file
5815 lib/silccore/silccommand.c.
5817 * Added silc_server_send_notify_ban to send the BAN notify
5818 type between routers.
5820 * Chaned the silc_notify_payload_encode to support that if
5821 argument is NULL it ignores and checks the next argument.
5822 Affected file lib/silccore/silcnotify.c.
5824 * Tested ban lists in router environment successfully.
5826 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Implemented BAN command to the server, in silcd/command.[ch].
5830 * Removed the BAN and INVITE_LIST modes from the CMODE command
5833 * Added function silc_string_match to regex match two strings.
5834 Affected files lib/silcutil/silcutil.[ch].
5836 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Redefined parts of the SilcChannelEntry in the server to support
5839 the new ban and invite lists.
5841 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Redefined the INVITE command. The same command can be used to
5844 invite individuals to the channel but also to manage the invite
5845 list of the channel (to add to and remove from the invite list).
5846 Updated the protocol specs.
5848 * Added new command SILC_COMMAND_BAN that can be used to manage
5849 the ban list of the channel. Updated the protocol specs.
5851 * Removed the channel modes: the SILC_CMODE_BAN and the
5852 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5853 in the CMODE command. The equivalent features are now available
5854 using INVITE and BAN commands. Updated the protocol specs.
5856 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5857 in the network about change in the current ban list. The notify
5858 type is not used by the client.
5860 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5861 support the invite lists.
5863 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Added new function silc_string_regexify that converts string
5866 including wildcard characters into regex string that can
5867 be used by the GNU regex library. Added into the file
5868 lib/silcutil/silcutil.[ch].
5870 Added silc_string_regex_combine to combine to regex strings
5871 into one so that they can be used as one regex string by
5872 the GNU regex library. Added into the file
5873 lib/silcutil/silcutil.[ch].
5875 Added silc_string_regex_match to match two strings. It returns
5876 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5878 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Imported GNU regex to the soruce tree into lib/contrib.
5881 Fixed some compiler warning from the regex.c.
5883 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Fixed MOTD command in the server to work in router environment.
5887 * Fixed the MOTD command in the client library to support
5888 the server argument in the command.
5890 * Added `nickname_len' argument to the silc_idlist_add_client
5891 in the server, as the `nickname' argument may be binary data
5894 * Added silc_idlist_get_channels to return all channels from
5897 * Implemented LIST command to the server. Affected file is
5900 * Implemented the LIST command to the client library and on the
5903 * Added [<user count>] argument to the LIST command reply.
5904 With private channels the user count is not shown.
5906 * Updated TODO and README.
5908 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * The client entry's data.registered must be TRUE even with
5911 global client entry on global client list. The data.registered
5912 is used to check whether the client is anymore in the network,
5913 for example with WHOWAS command so it must be valid.
5915 * Fixed the WHOWAS command in the server. It now actually works
5916 in router environment. Added function into silcd/command_reply.c
5917 silc_server_command_reply_whowas_save.
5919 * Added silc_idlist_purge function to the silcd/idlist.c
5920 to periodically purge the ID Cache.
5922 * Fixed INFO command in the server. It works now in router
5923 environment. Added <server name> argument to the INFO command
5924 reply. Updated the protocol specs.
5926 * Fixed minor bug in silc_idcache_purge to not purge if the
5927 expire value is zero.
5929 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5930 they were buggy because of the WHOWAS information.
5932 * Fixed local command MSG to handle the async resolving of
5933 the remote client properly. It used to fail the first MSG.
5934 Affected file silc/local_command.c.
5936 * Added `data_len' field to SilcIDCache context.
5938 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Update TODO. Todo in commands in the server.
5942 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5945 used by routers as broadcast packet to inform other routers
5946 about the changed user mode.
5948 Implemented the notify handling in the server. Affected file is
5949 silcd/packet_receive.c. Added the function
5950 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5952 * Added new generic Channel Payload and deprecated the New Channel
5953 Payload. The New Channel Payload is now the generic Channel
5956 * Added new argument `mode' to the silc_server_send_new_channel
5957 as it is required in the Channel Payload now.
5959 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5960 and created a new and real SilChannelPayload to represent the
5961 new generic Channel Payload. Implemented the encode/decode
5962 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5964 * Added silc_server_get_client_channel_list to return the list
5965 of channels the client has joined for WHOIS command reply.
5966 Affected file silcd/server.[ch].
5968 * Implemented the channel list sending in the WHOIS command reply
5969 in server and in the client.
5971 Implemented the channel list displaying on the user interface
5972 as well. Affected file silc/client_ops.c.
5974 * Added silc_channel_payload_parse_list to parse list of Channel
5975 Payloads. It returns SilcDList list of SilcChannelPayloads.
5976 Client for example can use this function to parse the list of
5977 channels it receives in the WHOIS command reply. The caller
5978 must free the list by calling silc_channel_payload_list_free.
5979 Affected files lib/silccore/silcchannel.[ch].
5981 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added one new argument <user mode> to the WHOIS command reply
5984 to return the mode of the user in SILC. Updated the protocol
5987 Implemented it to the server and client.
5989 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Fixed the mode printing on the user interface on joining.
5992 Affected file silc/client_ops.c.
5994 * Implemented the UMODE command and user modes in general to the
5995 client library and to the user interface.
5997 * Implemented the UMODE command to the server.
5999 * The server now sends UNKNOWN_COMMAND error status if client sends
6000 unknown command. Affected file silcd/command.c.
6002 * All server commands now handle the command identifier the right
6003 way when sending the command reply to the client. The client can
6004 use to identify the command replies with the identifier.
6006 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added silc_server_get_client_route to resolve the route to
6009 the client indicated by the client ID. Affected file is
6012 * Added silc_server_relay_packet as general function to relay
6013 packet to arbitrary destination. This deprecates functions
6014 like _send_private_message_key, _relay_notify etc. Affected
6015 file is silcd/packet_send.[ch].
6017 Removed silc_server_send_key_agreement,
6018 silc_server_send_private_message_key and
6019 silc_server_packet_relay_notify functions from the file
6020 silcd/packet_send.[ch].
6024 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6025 server. Affected file silcd/packet_receive.[ch].
6027 * Implemented the KILL command to the client. Implemented the
6028 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6029 Affected files lib/silcclient/command[_reply].c and
6030 lib/silcclient/client_notify.c. Implemented the KILL notify
6031 printing in the user inteface.
6033 * Fixed a lot silc_parse_nick memory leaks from the client
6034 library in the file lib/silcclient/command.c.
6036 * Changed the silc_server_send_notify_on_channels's `sender'
6037 argument from SilcSocketConnection to SilcClientEntry to
6038 check the sender as entry and not as connection object and not
6039 to send to the client provided as argument. The affected file
6040 is silcd/packet_send.[ch].
6042 * The notify packets that are destined directly to the client used
6043 to not to be processed by the server. Now changed that and the
6044 server processes all notify packets. After relaying the packet
6045 to the client the notify packet is processed in the server.
6047 * The silc_server_free_client_data now checks whether there is
6048 pending outgoing traffic for the client and purges the data to
6049 the network before removing the client entry.
6051 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6054 an client is killed from the SILC Network. Updated the protocol
6057 Added new function silc_server_send_notify_killed to the
6058 silcd/packet_send.[ch].
6060 * Added function silc_server_packet_relay_notify to relay notify
6061 packets that are destined directly to a client. In this case
6062 the server does not process the notify packets but merely relays
6063 it to the client. Affected file silcd/packet_send.[ch].
6065 Added also silc_server_packet_process_relay_notify to check
6066 whereto relay the notify. Affected file is
6067 silcd/packet_receive.[ch].
6069 * Implemented the KILL command to the server.
6073 * Added the backup schema desgined last fall to the protocol
6074 specs for everyone to see. The specification is in the
6075 *-spec-xx.txt draft and the packet type definitions for the
6076 backup routers is in *-pp-xx.txt draft. Thusly, added also
6077 new packet type SILC_PACKET_CELL_ROUTERS.
6079 * A big security problem in the implementation discovered. The
6080 signoff of an client did not cause new channel key generation
6081 which it of course should've done. The channel keys must be
6082 always re-generated when client leaves (or signoffs) the channel.
6083 The silc_server_remove_from_channels funtion now handles
6084 the channel key re-generation.
6086 * Added `sender' argument to the silc_server_send_notify_on_channels
6087 to not to send the client provided as argument. Affected file
6088 silcd/packet_send.[ch].
6090 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Implemented OPER and SILCOPER commands into the server and
6095 * Added silc_auth_verify and silc_auth_verify_data to verify
6096 the authentication directly from the authentication payload.
6097 It supports verifying both passphrase and public key based
6098 authentication. Affected file lib/silccore/silcauth.[ch].
6100 * Added `hash' field to the SilcIDListData structure. It is the
6101 hash negotiated in the SKE protocol. Affected file is
6104 * Slight redesigning of the SilcAuthPayload handling routines.
6105 Do not send SilcPKCS but SilcPublicKey as argument.
6107 * Implemented the public key authentication support to the
6108 serverconfig. The public key is loaded from the provided path
6109 and saved as authentication data to void * pointer. Thus,
6110 changed the unsigned char *auth_data to void *auth_data;
6112 * Fixed SHUTDOWN command to send the reply before the server
6113 is shutdown. :) Affected file silcd/command.c.
6115 * Fixed fatal bug in CONNECT command. The hostname was invalid
6116 memory and server crashed. Affected file silcd/command.c.
6118 * Fixed fatal bug in CLOSE command. The server_entry became
6119 invalid but was referenced later in the command. Affected file
6122 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Fixed fatal bug in failure packet handling. Server ignored
6125 the failure and thus crashed when it came.
6129 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6132 that the command may be executed only once in (about) 2 seconds.
6133 The old SILC_CF_LAG flag is same but allows command bursts up
6134 to five before limiting.
6136 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6137 server code. Various commands now includes the CF_LAG_STRICT
6138 flag to disallow any kind of miss-use of the command.
6140 * Fixed the silc_buffer_unformat to not to allocate any data
6141 if the length of the data is zero. It used to allocate the
6142 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6144 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Changed the format of AdminConnection configuration section
6147 in the server. Added username of the admin to the format.
6148 Affected files silcd/serverconfig.[ch].
6150 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6151 to return admin configuration data by host, username and/or
6154 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Implemented WHOWAS command to the server. Added the functions:
6158 silc_server_command_whowas_parse,
6159 silc_server_command_whowas_send_reply,
6160 silc_server_command_whowas_from_client and
6161 silc_server_command_whowas_from_server
6163 * Added <Client ID> argument to the WHOWAS command reply. Updated
6164 the protocol specs accordingly.
6166 * Implemented WHOWAS command and command_reply to the client
6169 Implemented the WHOWAS printing on the user interface.
6171 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Added new argument to the WHOWAS command reply, the real name.
6174 It is an optional argument. Updated the protocol specs.
6176 * Added SilcIDCacheDestructor callback that is registered when
6177 the SilcIDCache is allocated. The callback is called when
6178 an cache entry in the ID Cache expires, or is purged from the
6179 cache. Added into lib/silccore/idcache.[ch].
6181 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6182 to destruct the client entries when the cache entry expires.
6183 Other ID Cache's in server and in the client library ignores
6186 * If the ID Cache entry's `expire' field is zero then the entry
6187 never expires. Added boolean `expire' argument to the
6188 silc_idcache_add function in the lib/silccore/idcache.[ch].
6189 If it is TRUE the default expiry value is used.
6191 * Added silc_server_free_client_data_timeout that is registered
6192 when client disconnects. By default for 5 minutes we preserve
6193 the client entry for history - for WHOWAS command.
6195 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Added support to the server to enforce that commands are not
6198 executed more than once in 2 seconds. If server receives
6199 commands from client more frequently, timeout is registered
6200 to process the commands. Affected file silcd/command.c.
6201 Added new function silc_server_command_process_timeout.
6203 * Changed NICK_NOTIFY handling in client library to check that
6204 if the client's nickname was changed, so there is no need to
6205 resolve anything from the server.
6207 * Removed error printing from the WHOIS and IDENTIFY commands.
6208 If error occurs then it is ignored silently in the client library.
6209 The application, however, may map the received error to
6210 human readable error string. The application currently maps
6211 the NO_SUCH_NICKNAME error to string.
6213 * Made the command status message public to the application. Moved
6214 them from lib/silcclient/command_reply.c to
6215 lib/silcclient/command_reply.h. The application can map the
6216 received command status to the string with the
6217 silc_client_command_status_message function.
6219 * Added check to the server to check that client's ID is same
6220 as the Source ID in the packet the client sent. They must
6223 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Added dist-bzip hook to the Makefile.am to make bzip2
6226 compressed distributions.
6228 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Server now enforces the maximum length for the nickname and
6231 the channel as protocol specification dictates. 128 bytes for
6232 nickname and 256 bytes for channel name.
6234 * Moved the WHOIS printing to the application. The client libary
6235 does not print out the WHOIS information anymore, the application
6236 must do it. Renamed silc_client_command_reply_whois_print to
6237 the silc_client_command_reply_whois_save.
6239 The client's idle time is also sent to the application now, and
6240 the idle is shown on screen.
6242 * Added silc_client_command_reply_identify_save to save the
6243 received IDENTIFY entries.
6245 * Do not check for channel private keys in message sending and
6246 reception if the channel does not have the PRIVKEY mode set.
6247 Affected file lib/silclient/client_channel.c.
6249 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6252 just surfaced after chaning the JOIN procedure.
6254 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Added silc_client_get_clients_by_list to get client entries
6257 from Client ID list, that is returned for example by JOIN
6258 and USERS command replies. The application should use this
6259 function for example when JOIN command reply is received to
6260 resolve the clients already on the channel (library does not
6261 do that anymore as USERS command reply is not used in the JOIN
6262 procedure anymore). Affected files lib/silcclient/silcapi.h and
6263 lib/silcclient/idlist.c.
6265 * JOIN command reply and USERS command reply returns now SilcBuffer
6266 pointers instead of unsigned char pointers when returning
6267 the client list and mode list.
6269 * Added <Client ID> argument to the JOIN command reply, mainly
6270 for the server to identify for which client the command was
6271 originally sent. Updated protocol specs accordingly.
6273 * Added SilcDlist private_key pointer to the SilcChannelEntry
6274 in the client to support the channel private keys. Affected
6275 file is lib/silcclient/idlist.h.
6277 * Added SilcChannelPrivateKey argument to the function
6278 silc_client_send_channel_message so that application can choose
6279 to use specific private ke if it wants to. If it is not provided,
6280 the normal channel key is used, unless private keys are set.
6281 In this case the first (key that was added first) is used
6282 as the encryption key.
6284 * Implemented the support for channel private key handling.
6285 Implemented the following functions:
6287 silc_client_add_channel_private_key,
6288 silc_client_del_channel_private_keys,
6289 silc_client_del_channel_private_key,
6290 silc_client_list_channel_private_keys and
6291 silc_client_free_channel_private_keys
6293 Affected file lib/silcclient/client_channel.c.
6295 * Added the support for the private keys in the channel message
6296 sending and encryption and in the message reception and
6297 decryption. Affected funtions are
6298 silc_client_send_channel_message and silc_client_channel_message.
6300 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added SKE's key verify callback to the client library's
6303 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6305 * Removed the statement that server (or router) must send USERS
6306 command reply when joining to the channel so that the client
6307 knows who are on the channel. Instead, the client list and
6308 client's mode list is now sent in the JOIN command reply to the
6309 client who joined channel. This is better solution.
6311 * Added function silc_server_get_users_on_channel and function
6312 silc_server_save_users_on_channel to the silcd/server.[ch].
6314 * Removed function silc_server_command_send_users from the
6317 * Do not show topic on the client library anymore. The topic is
6318 sent in the command reply notify to the application and the
6319 application must show the topic now.
6321 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added client searching by nickname hash into the IDENTIFY and
6324 WHOIS commands in the server as they were clearly missing from
6325 them. Affected file is silcd/command.c.
6327 * Fixed a bug in private message receiving in the client library.
6328 The remote ID was freed and it wasn't supposed, now it is
6331 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Minor fix to the channel payload; allocate the data area, as it
6334 needs to be of specific length.
6336 * If the key agreement port is zero then the operating
6337 system will define the bound port. Affected files are
6338 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6340 * Added new function silc_channel_payload_decrypt into the file
6341 lib/silccore/silcchannel.[ch].
6343 * Moved the channel message etc, check from silc_packet_decrypt
6344 to applications. The library calls now a generic
6345 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6346 when the packet is either normal or special. This was done to
6347 allow more wide range of checking that was not allowed when
6348 the code was in library. Now applications can do virtually any
6349 checks to the packet and return to the library the decision how
6350 the packet should be processed. Affected files are
6351 lib/silccore/silcpacket.[ch].
6353 Added silc_server_packet_decrypt_check to the server and
6354 silc_client_packet_decrypt_check to the client library.
6356 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6357 to send with specified source and destination information.
6359 * Channel message delivery between routers was broken after the
6360 channel key distribution was fixed earlier. The channel key
6361 was used be to distributed to other routers as well which is not
6362 allowed by the protocol. Now this is fixed and channel keys
6363 really are cell specific and the channel message delivery between
6364 routers comply with the protocol specification.
6366 * Fixed various commands in server to check also the global list
6367 for the channel entry and not just the local list. The affected
6368 file silcd/command.c.
6370 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Added assert()s to buffer formatting and unformatting routines
6373 to assert (if --enable-debug) when error occurs. Affected
6374 file: lib/silcutil/silcbuffmt.c.
6376 * Changed to auto-reconnect to check whether the remote host is
6377 router and register the re-connect timeout if it is. It used
6378 to check that whether we are normal server, but router must do
6379 auto-reconnect with another router as well. Affected file
6382 * Removed the [<key len>] option from CMODE command as the cipher
6383 name decides the key length, nowadays. See the defined ciphers
6384 from the protocol specification.
6386 * Added [<hmac>] option to the CMODE command to define the HMAC
6387 for the channel. Added SILC_CMODE_HMAC channel mode.
6389 * Added [<hmac>] option for the JOIN command so that user can
6390 select which HMAC is used to compute the MACs of the channel
6393 * Added Hmac field to the Channel Message Payload. The integrity
6394 of plaintext channel messages are now protected by computing
6395 MAC of the message and attaching the MAC to the payload. The
6396 MAC is encrypted. Now, it is clear that this causes some
6397 overhead to the size of the packet but rationale for this is that
6398 now the receiver can verify whether the channel message decrypted
6399 correctly and also when private keys are set for the channel the
6400 receiver can decrypt the packet with several keys and check from
6401 the MAC which key decrypted the message correctly.
6403 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6404 lib/silccrypt/silccipher.[ch].
6406 * Added silc_hash_len to return the digest length into the
6407 lib/silcrypt/silchash.[ch].
6409 * Rewrote parts of Silc Channel Payload interface in the
6410 lib/silccore/silcchannel.[ch]. The encode function now also
6411 encrypts the packet and parse function decrypts it.
6413 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Fixed a minor formatting bug in the SKE's key material processing.
6416 It actually might have processed the keys wrong way resulting
6419 * Redefined the mandatory HMAC algorithms and added new algorithms.
6420 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6421 and hmac-md5 truncated to 96 bits. The mandatory is now
6422 hmac-sha1-96. Rest are optional (including the one that used
6423 to be mandatory). Rationale for this is that the truncated HMAC
6424 length is sufficient from security point of view and can actually
6425 make the attack against the HMAC harder. Also, the truncated
6426 HMAC causes less overhead to the packets. See the RFC2104 for
6429 * Added new [hmac] configuration section. The SKE used to use
6430 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6431 is of course wrong. The official names that must be proposed in
6432 the SKE are the ones defined in the protocol specification
6433 (hmac-sha1-96 for example). The user can configure any hmac
6434 using any hash function configured in the [hash] section. At
6435 least, the mandatory must be configured.
6437 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6439 * Added HMAC list to the SKE proposal list. It has now both
6440 hash algorithm list and HMAC list. This makes the protocol
6441 incompatible with previous versions. The SKE now seems to work
6442 the way it is supposed to work, for the first time actually.
6444 * Defined plain Hash algorithms to the protocol specification.
6447 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6449 * Implemented support for key agreement packets into the server.
6450 Added functions silc_server_key_agreement and
6451 silc_server_send_key_agreement. Other than these functions,
6452 server has nothing to do with this packet.
6454 * Added support for private message key packets into the server.
6455 Added functions silc_server_private_message_key and
6456 silc_server_send_private_message_key.
6460 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6461 called in the protocol's final callback instead in the END
6462 protocol state. This makes a little more sense and in the same
6463 time in client we can use the same protocol routines for normal
6464 key exchange and to key agreement packet handling as well.
6466 * Added to both client's and server's KE protocol context the
6467 SilcSKEKeyMaterial pointer to save the key material. We will
6468 bring the key material to the protocol's final callback by doing
6469 this. The final callback must free the key material.
6471 * Added SKE's packet_send callback into client's KE protocol
6472 context so that the caller can choose what packet sending function
6473 is used. This way we can use different packet sending when
6474 doing normal SKE when doing key agreement packet handling (in
6475 the key agreement packet handling we do not want to encrypt
6478 * Implemented the responder side of the key agreement routines
6479 in the client. The client can now bind to specified port and
6480 accept incoming key negotiation. The key material is passed
6481 to the application after the protocol is over.
6483 * Implemented the processing of incoming Key Agreement packet
6484 in the client. Added function silc_client_key_agreement to
6487 * Implemented the intiator side of the key agreement routines
6488 in the client. The client can now initiate key agreement with
6489 another remote client. The key material is passed to the
6490 application after the protocol is over.
6492 * Created client_keyagr.c to include all the key agreement
6495 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6496 SILC_TASK_CALLBACK except that it is not static.
6498 * Created client_notify.c and moved the Notify packet handling
6499 from the client.[ch] into that file.
6501 * Created client_prvmsg.c and moved all private message and
6502 private message key routines from the client.[ch] into that file.
6504 * Create client_channel.c and moved all channel message and
6505 channel private key routines from the client.[ch] into that file.
6507 * Changed silc_client_get_client_by_id_resolve to resolve with
6508 WHOIS command instead of IDENTIFY command, in the file
6509 lib/silclient/idlist.c.
6511 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Implemented the SKE's responder side to the Client library.
6515 * When FAILURE is received to the protocol do not trust it
6516 blindly. Register a timeout to wait whether the remote closes
6517 the connection as it should do it, only after that process the
6518 actual failure. This was changed to both client and server.
6520 * Added client_internal.h to include some of the structures
6521 there instead of client.h in lib/silcclient/.
6523 * Added function silc_task_unregister_by_callback to unregister
6524 timeouts by the callback function.
6526 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Some "Incomplete WHOIS info" errors has been appearing on the
6529 log files. Took away the entry->userinfo check from WHOIS
6530 reply sending. The entry->userinfo is now " " if client did not
6531 provide one. I thought this was fixed earlier but something
6532 is wrong still. Let's see if the error still appears.
6534 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Fixed a minor bug in the login when the channel key is
6537 re-generated in the server. It used to generate the key in
6538 wrong order and thus caused problems in the channel traffic.
6540 * Fixed a minor bug in channel key distsribution after
6541 KICK command. The key was not sent to the router even though
6544 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Added silc_ske_process_key_material_data as generic routine
6547 to process any key material as the SILC protocol dictates. The
6548 function is used by the actual SKE library but can be used by
6549 applications as well. This relates to the private message keys
6550 and the channel private keys since they must be processed the
6551 same way the normal SILC session keys. The protocol dictates
6552 this. Affected files: lib/silcske/silcske.[ch].
6554 Added also silc_ske_free_key_material to free the
6555 SilcSKEKeyMaterial structure.
6557 * Defined silc_cipher_set_key function to set the key for
6558 cipher without using the object's method function. The affected
6559 files: lib/silccrypt/silccipher.[ch].
6561 * Implemented silc silc_client_add_private_message_key,
6562 silc_client_add_private_message_key_ske,
6563 silc_client_del_private_message_key,
6564 silc_client_list_private_message_keys and
6565 silc_client_free_private_message_keys functions in the
6568 Added functions silc_client_send_private_message_key to send
6569 the Private Message Key payload and silc_client_private_message_key
6570 to handle incoming Private Message Key payload.
6572 * Added Cipher field to the Private Message Key payload to set
6573 the cipher to be used. If ignored, the default cipher defined
6574 in the SILC protocol (aes-256-cbc) is used.
6576 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Removed lib/silcclient/ops.h file.
6580 Redefined parts of the SILC Client Library API. Created new
6581 file silcapi.h that deprecates the ops.h file and defines the
6582 published Client Library API. Defined also private message key
6583 API and channel private key API into the file.
6585 This is the file that the application must include from the
6586 SILC Client Library. Other files need not be included by
6587 the application anymore.
6589 * Added new key_agreement client operation callback and also
6590 defined the Key Agreement library API for the application.
6592 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6595 is used by clients to request key negotiation between another
6596 client in the SILC network. If the negotiation is started it
6597 is performed using the SKE protocol. The result of the
6598 negotiation, the secret key material, can be used for example
6599 as private message key.
6601 Implemented the Key Agreement payload into the files
6602 lib/silccore/silauth.[ch].
6604 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Redefined ciphers for the SILC protocol. Added some new ciphers
6607 and defined the key lengths for the algorithms. Changed the
6608 code accordingly. The default key length is now 256 bits.
6610 * Fixed SKE key distribution function silc_ske_process_key_material
6611 when the key length is more than 128 bits. The default key
6612 length in SILC is now 256 bits.
6614 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6615 to indicate unsupported algorithm.
6617 * Renamed rijndael.c to aes.c and all functions as well.
6619 * Fixed a long standing channel key setting bug in client library.
6620 Weird that it has never surfaced before.
6622 * Fixed bug in channel deletion. If the entire channel is removed
6623 then it must also delete the references of the channel entry
6624 from the client's channel list as the client's channel entry and
6625 the channel's client entry share same memory.
6627 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Implemented CONNECT and SHUTDOWN commands in the client.
6631 * Implemented CLOSE command to the client.
6633 * Added the function silc_idlist_find_server_by_name into the
6634 files silcd/idlist.[ch].
6636 Added the function silc_idlist_find_server_by_conn into the
6637 files silcd/idlist.[ch].
6639 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * DIE command was renamed to SHUTDOWN. Updated the both code
6644 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6645 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6647 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6650 * Added function silc_server_create_connection function to create
6651 connection to remote router. My server implementation actually
6652 does not allow router to connect to normal server (it expects
6653 that normal server always initiates the connection to the router)
6654 so the CONNECT command is only good for connecting to another
6657 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6660 or some other client was kicked from the channel.
6662 Implemented the handling of the notify type to both client
6665 Implemented silc_server_send_notify_kicked to send the KICKED
6666 notify. It is used to send it to the server's primary router.
6668 * Implemented the KICK command into server and client.
6670 * Added `query' argument to the silc_idlist_get_client function
6671 to indicate whether to query the client from server or not if
6674 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6675 to indicate that the client is not channel founder.
6679 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6681 * Removed the rng context from SilcPacketContext structure and
6682 changed that the packet routine uses the Global RNG API.
6684 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added support for quit message that client can "leave" on the
6687 channel when it quits the SILC. It is ditributed inside the
6688 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6690 Added silc_server_free_client_data that will take the
6691 signoff message as argument.
6693 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6695 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Updated parts of the protocol specification to keep it up
6700 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6703 payloads in one packet.
6705 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6706 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6707 use now the new List flag.
6709 * Also deprecated the following packet types: REPLACE_ID,
6710 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6712 * Added list support for Notify packet in server.
6714 * Added silc_server_send_notify_channel_change to send the
6715 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6716 the silc_server_send_replace_id.
6718 * Added silc_server_send_notify_nick_change to send the
6719 NICK_CHANGE notify type. Deprecates the function
6720 silc_server_send_replace_id.
6722 * Added silc_server_send_notify_join to send the JOIN notify type.
6723 Deprecates the function silc_server_send_new_channel_user.
6725 * Added silc_server_send_notify_leave to send LEAVE notify type.
6726 Deprecates the function silc_server_send_remove_channel_user.
6728 * Added silc_server_send_notify_cmode and
6729 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6730 types. Deprecates the silc_server_send_set_mode function.
6732 * Added SERVER_SIGNOFF notify type to indicate that server has
6733 quit. This means that all clients on the channel from that
6734 server will drop. This can be also used when netsplit happens.
6736 Deprecated REMOVE_ID packet type since it is not needed anymore
6739 Added silc_server_send_notify_server_signoff to send the
6740 SERVER_SIGNOFF notify type. Deprecates the function
6741 silc_server_send_remove_id.
6743 Added also silc_server_send_notify_signoff to send the
6744 SIGNOFF notify type.
6746 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6747 SILC protocol from this day on. Changed the protocol
6748 specification as well.
6750 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6751 notify type. It is used between routers to notify about
6752 topic changes on a channel.
6754 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6757 * Partly updated the protocol specification to comply with the
6758 changes now made. It is still though a bit outdated.
6760 * The JOIN notify type now takes one extra argument <Channel ID>.
6761 The packet used to be destined to the channel but now the
6762 JOIN type may be sent as list thus it is impossible to
6763 destine it to any specific channel. By adding this argument
6764 it is again possible.
6766 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Added CREDITS file. The CHANGES and CREDITS file will appear
6769 in the distribution as well.
6771 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6774 types in the server's silcd/packet_receive.c.
6776 * Implemented CMODE and CUMODE to work in router environment.
6778 * Fixed minor encoding and decoding buglet from the
6779 lib/silccore/silcmode.c.
6781 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6784 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6786 * Changed all SilcConfigServer* and silc_config_server* to
6787 SilcServerConfig* and silc_server_config*, respectively.
6790 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Associated the ID (client or server ID) to the Authentication
6793 Payload to avoid any possibility of forging. Updated the
6794 protocol specification and the code accordingly.
6796 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * The RSA key length is now save to the RsaKey context in the
6799 key generation process in lib/silccrypt/rsa.c. The key length
6800 is now used to figure out the maximum size of the block allowed
6801 to be encrypted/signed.
6803 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6804 is equivalent to the silc_mp_mp2bin but does not allocate any
6807 * Changed silc_mp_mp2bin API to take length argument. If it is
6808 non-zero then the buffer is allocated that large. If zero, then
6809 the size is approximated using silc_mp_sizeinbase, which however
6812 * Created Global RNG API which is global RNG that application can
6813 initialize. After initializing, any routine anywhere in the
6814 code (including library) can use RNG without allocating a new
6815 RNG object. This was done to allow this sort of use of the
6816 RNG in code that has no chance to allocate RNG object. All
6817 applications currently allocate this and many routines in the
6818 library use this. Affected file lib/silccrypt/silcrng.[ch].
6820 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6821 it to use the Global RNG API.
6823 * Defined Authentication Payload into protocol specification that
6824 is used during SILC session to authenticate entities. It is
6825 used for example by client to authenticate itself to the server
6826 to obtain server operator privileges.
6828 Implemented this payload into the lib/silccore/silcauth.[ch].
6829 Implemented also routines for public key based authentication
6830 as the new protocol specification dictates.
6832 Moved definitions of different authentication methods from
6833 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6835 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6836 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6837 silc_pkcs_verify_with_hash functions into the file
6838 lib/silccrypt/silcpkcs.[ch].
6840 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * The client entry's userinfo pointer must be always valid.
6843 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6844 will fail since it requires the userinfo. Now, the userinfo
6845 is allocated as "" if actual userinfo does not exist. Actually,
6846 it must exist and it is totally Ok to drop client connections
6847 that does not announce the userinfo. However, we will make
6848 this workaround for now.
6850 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6851 to return the remote port by socket.
6853 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6856 SILC_SERVER_PENDING_EXEC and added an new macro
6857 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6858 data or when error occurs while processing the pending command.
6860 Added new argument `destructor' into silc_server_command_pending
6861 and to the SilcServerCommandPending object. This destructor is
6862 now called after calling the pending callback or if error occurs
6863 immediately. If error occurs the actual pending callback won't
6864 be called at all - only the destructor. The destructor may be
6865 NULL if destructor is not needed.
6867 All this applies for client library code as well. Similar
6868 changes were made there as well for the pending commands.
6870 In the client, the application must now allocate the
6871 SilcClientCommandContext with the silc_client_command_alloc
6874 * Added reference counter to the SilcServerCommandContext. Added
6875 function silc_server_command_alloc and silc_server_command_dup
6878 Same type of functions added to the client library for the same
6881 * Removed the cmd_ident from IDListData away since it is now
6882 global for all connections. It is the command identifier used
6883 in command sending and with pending commands. The affected file
6886 * Added reference counter to the SilcSocketConnection objecet to
6887 indicate the usage count of the object. The object won't be
6888 freed untill the reference counter hits zero. Currently only
6889 server uses this, and client ignores it. The client must be
6890 set to use this too later. The affected files are
6891 lib/silccore/silcsockconn.[ch]. Added also the function
6892 silc_socket_dup to increase the reference counter.
6894 This was mainly added because it is possible that the socket
6895 is removed underneath of pending command or other async
6896 operation. Now it won't be free'd and proper DISCONNECTING
6897 flags, etc. can be set to avoid sending data to connection that
6898 is not valid anymore.
6900 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6901 the connection. After that it sets SILC_SET_DISCONNECTED.
6902 It is, however, possible that the socket data is not still freed.
6903 The silc_server_packet_process now checks that data is not
6904 read or written to connection that is DISCONNECTED. The socket
6905 get's freed when the reference counter hits zero.
6907 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Changed the client operation API: channel_message operation's
6910 `sender' is now the client entry of the sender, not the nickname
6911 and the `channel' is the channel entry, not the channel name.
6913 In the private_message operation the `sender' is now also the
6914 client entry of the sender not the nickname.
6916 Affected file is lib/silcclient/ops.h and all applications
6917 using the client operations.
6919 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Moved the calling of ops->connect() from connect_to_server_final
6922 into receive_new_id functin since that is the point when the
6923 client is actually allowed to send traffic to network. The
6924 affected file is lib/silcclient/client.c.
6926 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6929 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6930 (if needs broadcasting) instead of broadcasting the packets one
6931 by one which would make a burst in the network traffic.
6933 * Added `broadcast' argument to the functions in silcd/server.[ch]
6934 silc_server_create_new_channel[_with_id] to indicate whether
6935 to send New Channel packet to primary router.
6937 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Added new function into the silcd/server.[ch] files:
6940 silc_server_create_new_channel_with_id to create new channel with
6941 already existing Channel ID.
6943 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6944 lib/silccore/silcpacket.h. This packet is used t send list of
6945 Set Mode payloads inside one packet. Server uses this to set
6946 the modes for the channels and clients on those channels, that it
6947 announced to the router when it connected to it. The protocol
6948 specification has been updated accordingly.
6950 * The silc_server_new_channel did not handle the packet coming
6951 from normal server as it normally does not send that. However,
6952 when it announces its channels it does send it. Implemented
6953 the support for that.
6955 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6956 into the file lib/silccore/id.h.
6958 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Fixed memory leaks in the functions silc_idlist_del_client,
6961 silc_idlist_del_channel and silc_idlist_del_server in the file
6962 silcd/idlist.c. All of those leaked like a sieve.
6964 * Fixed some small memory leaks in the client's function
6965 silc_client_notify_by_server.
6967 * Added functions into silcd/server.c: silc_server_announce_clients,
6968 silc_server_announce_channels and silc_server_announce_server.
6969 These functions are used by normal and router server to announce
6970 to its primary router about clients, channels and servers (when
6971 router) that we own. This is done after we've connected to the
6974 These functions effectively implements the following packet types:
6975 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6976 and SILC_PACKET_NEW_ID_LIST.
6978 * Added new functions into the silcd/packet_receive.[ch]:
6979 silc_server_new_id_list, silc_server_new_channel_list and
6980 silc_server_new_channel_user_list to handle the incoming
6981 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6983 * Added support of changing Channel ID in the function
6984 silc_server_replace_id. If the server that announces a channel
6985 to the router already exists in the router (with same name but
6986 with different Channel ID), router is responsible to send
6987 Replace ID packet to the server and force the server to change
6988 the Channel ID to the one router has.
6990 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6991 client that the Channel ID has been changed by the router. The
6992 normal server sends this to the client. Client must start using
6993 the new Channel ID as the channel's ID.
6995 Implemented handling of this new type into lib/silcclient/client.c
6996 into the function silc_client_notify_by_server.
6998 * Added new function silc_idlist_replace_channel_id into the files
6999 silcd/idlist.[ch] to replace the Channel ID.
7001 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Call silc_server_command_identify_check always when processing
7004 the IDENTIFY command in silcd/command.c
7006 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7008 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7009 send keepalive packets. The packet can be sent by clients,
7010 servers and routers.
7012 Added function silc_socket_set_heartbeat into the file
7013 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7014 If not set, the heartbeat is not performed. The actual
7015 heartbeat is implemented in the low level socket connection
7016 library. However, application is responsible of actually
7019 Added silc_server_send_heartbeat to send the actual heartbeat
7020 packet into silcd/packet_send.[ch]. Server now performs
7021 keepalive with all connections.
7023 * Added silc_task_get_first function into lib/silcutil/silctask.c
7024 to return the timeout task with shortest timeout. There was a bug
7025 in task unregistration that caused problems. TODO has been
7026 updated to include that task system must be rewritten.
7028 * The client library will now resolve the client information when
7029 receiving JOIN notify from server for client that we know but
7030 have incomplete information.
7032 * Rewrote parts of silc_server_remove_from_channels and
7033 silc_server_remove_from_one_channel as they did not remove the
7034 channel in some circumstances even though they should've.
7036 * Encryption problem encountered in server:
7038 The LEAVE command used to send the Channel Key packet to the
7039 router immediately after generating it. However, the code
7040 had earlier sent Remove Channel user packet but not immediately,
7041 ie. it was put to queue. The order of packets in the router
7042 was that Channel Key packet was first and Remove Channel User
7043 packet was second, even though they were encrypted in the
7044 reverse order. For this reason, MAC check failed. Now, this
7045 is fixed by not sending the Channel Key packet immediately but
7046 putting it to queue. However, this is more fundamental problem:
7047 packets that are in queue should actually not be encrypted
7048 because packets that are sent immediately gets encrypted
7049 actually with wrong IV (and thus MAC check fails). So, packets
7050 that are in queue should be encrypted when they are sent to
7051 the wire and not when they put to the queue.
7053 However, the problem is that the current system has not been
7054 designed to work that way. Instead, the packet is encrypted
7055 as soon as possible and left to the queue. The queue is then
7056 just purged into wire. There won't be any fixes for this
7057 any time soon. So, the current semantic for packet sending
7060 o If you send packet to remote host and do not force the send
7061 (the packet will be in queue) then all subsequent packets to the
7062 same remote host must also be put to the queue. Only after the
7063 queue has been purged is it safe again to force the packet
7066 o If you send all packets immediately then it safe to send
7067 any of subsequent packets through the queue, however, after
7068 the first packet is put to queue then any subsequent packets
7069 must also be put to the queue.
7071 Follow these rules and everything works fine.
7073 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7075 * Added new function silc_server_remove_clients_by_server to
7076 remove all client entries from ID list when the server connection
7077 is lost. In this case it is also important to invalidate all
7078 client entires as they hold the invalid server entry. This
7079 fixes fatal bug when server has lost connection and will reconnect
7082 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Made some sanity checks to silc_server_daemonise like to check
7085 whether the requested user and group actually exists.
7087 * Added sanity check to SKE's silc_ske_responder_finish to check
7088 that the public and private key actually is valid.
7090 * Invalidate the client's nickname when receiving Replace ID
7091 packet and the Client ID is being replaced. This means that the
7092 server will query the nickname if someone needs it (client)
7095 * Sort the ID Cache in client library when the ID Cache data
7096 has changed (needs sorting).
7098 * Do not allow for SILC client to create several connections to
7099 several servers. The client does not support windows right now
7100 and generating multiple connections causes weird behaviour.
7102 Irssi-silc client does support windows and can handle several
7103 connections without problems, see: www.irssi.org and SILC plugin.
7105 * Fixed some places where client was added to the IDList. The
7106 rule of thumb is following (in order to get everything right):
7107 If the client is directly connected local client then the
7108 `connection' argument must be set and `router' argument must be
7109 NULL to silc_idlist_add_client function. If the client is not
7110 directly connected client then the `router' argument must
7111 bet set and the `connection' argument must be NULL to the
7112 silc_idlist_add_client function.
7114 * The funtion silc_server_packet_send_local_channel actually did
7115 not check whether the client was locally connected or not. It
7116 does that now. Fixed a bug related to LEAVE command.
7118 * Fixed Remove Channel User payload parsing bug in server's
7119 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7121 * The server's silc_server_save_channel_key now checks also the
7122 global ID list for the channel as it might not be in the local
7123 list. Fixed a bug related to LEAVE command.
7125 * Is this the end of the [<unknown>] buglet that has been lurking
7126 around for a long time? A little for loop fix in server's
7127 silc_server_command_whois_parse that is used by both IDENTIFY
7128 and WHOIS command. At least, this was a clear bug and a cause
7129 of one type of [<unknown>] buglet.
7131 * WHOIS and IDENTIFY commands call the function
7132 silc_server_command_[whois/identify]_check function even if
7133 we are not router server.
7135 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Added --with-gmp configuration option. If set the GMP
7138 is always compiled in the SILC source tree. If not set then
7139 it is checked whether the system has the GMP3 installed. If
7140 it has then the GMP won't be compiled (the system's headers
7141 and library is used), if it doesn't have it then the GMP is
7142 compiled in the SILC source tree.
7144 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Changed RSA private exponent generation to what PKCS #1
7147 suggests. We try to find the smallest possible d by doing
7148 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7149 not security fix but optimization.
7151 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added new config entry [Identity] to fork the server and run
7154 it as specific user and group. A patch from Bostik.
7156 * Imported Dotconf configuration library into lib/dotconf.
7157 This will be used to create the SILC configuration files later.
7158 It will appear in the distsribution after this commit.
7160 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * A big code auditing weekend happening. Auditing code for
7163 obvious mistakes, bugs and errors. Also, removing any code
7166 Removed files for being obsolete:
7168 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7169 inline in the file lib/silcutil/silcbuffer.h)
7171 o lib/silcutil/silcbufutil.c (the header has inline versions)
7173 Changed code to fix possible error conditions:
7175 o The buffer formatting routines now check that the destination
7176 buffer really has enough space to add the data. This applies for
7177 both buffer formatting and unformatting
7178 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7179 unformatting was changed to accomodate following rules:
7180 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7181 sent to the function while XXX_*STRING will not allocate or copy
7182 the data into the buffer. Instead it sets the pointer from the
7183 buffer into the pointer sent as argument (XXX_*STRING used to
7184 require that the pointer must be allocated already). This change
7185 makes this whole thing a bit more consistent and more optimized
7186 (note that the data returned in the unformatting with XXX_*STRING
7187 must not be freed now). The routines return now -1 on error.
7189 o Tried to find all code that use buffer_format and buffer_unformat
7190 and added return value checking to prevent formatting and
7191 especially unformatting errors and possible subsequent fatal
7194 o Changed ske->x and ske->KEY to mallocated pointers in
7195 lib/silcske/silcske.h. Fixed possible data and memory leak.
7197 o Added return value checking to all *_parse* functions. Fixed
7198 many memory leaks as well.
7200 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7201 so that buffer overflows would not happen. All code now also
7202 checks the return value as it can fail.
7204 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added reconnection support to server if the normal server looses
7207 its connection to the router (for example if router is rebooted).
7208 The server performs normal reconnection strategy implemented
7209 to the server. Affected file silcd/server.c.
7211 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7213 * Added new packet type SILC_PACKET_SET_MODE that is used to
7214 distribute the information about changed modes (for clients,
7215 channels and clients channel modes) to all routers in the
7216 network. Updated the protocol specification accordingly.
7218 Added functions into silcd/packet_send.c and
7219 silcd/packet_receive.c: silc_server_send_set_mode,
7220 silc_server_set_mode.
7222 Added new files silcmode.[ch] into lib/silccore that implements
7223 the encoding and decoding of Set Mode Payload. Added new type
7224 SilcSetModePayload. Moved the definitions of different modes
7225 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7227 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7229 * Oops, a little mistake in server's connection authentication
7230 protocol. The protocol is not ended with FAILURE but with
7231 SUCCESS if the authentication is Ok. :) Affected file is
7234 * Implemented NICK_CHANGE notify handling in server in the file
7235 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7236 the local clients on the channel. After the changing nickname
7237 in router environment snhould work and the [<unknown>] nickname
7238 should appear no more.
7240 The silc_server_replace_id function that receives the Replace ID
7241 payload now sends the NICK_CHANGE notify type also in the file
7242 silcd/packet_receive.c
7244 * Changed WHOIS and IDENTIFY command to support the maximum amount
7245 of arguments defined in protocol specs (3328 arguments). This
7246 fixed a bug that caused problems when there were more than three
7249 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Added extra parameter, command identifier, to the
7252 silc_client_send_command so that explicit command identifier
7255 Changed that ID list routines uses specific command identifier
7256 when sending WHOIS/IDENTIFY requests to the server so that they
7257 can be identified when the reply comes back.
7259 Affected files lib/silcclient/command.[ch],
7260 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7262 * Added `sender' argument to silc_server_packet_send_to_channel
7263 to indicaet the sender who originally sent the packet to us
7264 that we are now re-sending. Ignored if NULL. Affected file
7265 silcd/packet_send.[ch].
7267 * Added some server statistics support in silcd/server_internal.h
7268 SilcServerStatistics structure and around the server code. Also
7269 send some nice statistics information when client is connecting
7272 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Fixed channel ID decoding in server's JOIN command reply in
7275 silcd/command_reply.c
7277 * Fixed braodcasting of replace ID payload to not to send it if
7278 we are standalone server in silcd/packet_receive.c.
7280 * Fixed all channel message sending routines to not to send
7281 packets to clients that has router set, since they are routed
7282 separately in the same function earlier. Affects file
7283 silcd/packet_send.c and all channel packet sending functions.
7285 * In USERS reply, res_argv[i] are not allocated, the table
7286 is allocated. Thus changed that free the table, not its
7289 * In server's whois_check and identify_check if the client is
7290 locally connected do not send any WHOIS commands - they are not
7293 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Fixed some minor bugs in client when sending WHOIS command. The
7296 arguments was in wrong order.
7298 * Removed statis function add_to_channel from server in
7299 silcd/command.c that was previously used with the joining but
7302 * Tested USERS command in router environment successfully with two
7303 routers, two servers and two clients.
7305 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Reorganized the USERS command and command reply in client library
7308 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7309 When the command is given by user we register a pending command
7310 callback that will reprocess the command after the reply has been
7311 received from the server. When reprocessing the packet we then
7312 display the information. Thus, the USERS information is displayed
7313 now in the command callback instead of in the command reply
7314 callback. The processing of the command is same as previously
7315 when server has sent the command reply in the JOINing process.
7317 * Added to USERS command in silcd/command_reply.c to join the client,
7318 we didn't use to know about, to the channel after we've created
7319 a client entry for it. Also, for clienet we did know already still
7320 check whether it is on the channel or not and add it if not.
7322 * Removed silc_server_command_join_notify as the function and its
7325 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Changed the client's pending command handling to the same as the
7328 server's pending command handling. It is also now possible to
7329 execute command reply functions from other command reply
7330 function as the function callbacks for commands and command
7331 replies are one and same. The pending commands are not static
7332 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7333 in client connection context. Thus, pending commands are server
7334 connection specific as it is convenient.
7336 Changed the function silc_client_command_pending and
7337 silc_client_command_pending_del and added new function
7338 silc_client_command_pending_check. Removed the
7339 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7342 * Added cmd_ident, current command identifier, to the client
7343 connection context in lib/silcclient/client.h to keep track on
7344 command identifiers used in command sending. Client's command reply
7345 function handling now supports the mandatory command identifiers.
7347 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7348 funtions in client to fully support pending command callbacks.
7350 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7351 as one of the arguments to the application in the command reply
7354 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7355 before first releasing SILC but came back. Now it is removed again
7356 and should come back nomore. The FORWARDED flag was used only
7357 by the JOINing procedure by forwarding the command packet to router.
7358 Now, the JOINing procedure has been changed to more generic (due
7359 to various router environment issues) and FORWARDED is not needed
7360 anymore for anything. The protocol specification is yet to be
7363 Now, removed silc_server_packet_forward from server and the flag
7364 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7366 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7368 * Renamed NAMES command to USERS command. The NAMES was named that
7369 due to historical reasons. Now it is renamed. Also, rewrote
7370 parts of the USERS command. The nickname list is not sent anymore
7371 by the server. Only Client ID and mode lists are sent in the USERS
7372 command. Changed this also to the protocol specification.
7374 The client now resolves the names and stuff after it receives
7375 the USERS list from the server when joining to the channel.
7377 * WHOIS and IDENTIFY commands has been changed to support multiple
7378 Client ID's per command. One can now search for multiple users
7379 in the network by sending only one WHOIS or IDENTIFY command.
7380 Changed the code and the protocol specifications.
7382 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7383 uses silc_server_command_whois_parse to parse the request. */
7385 * If normal server, do not parse the WHOIS and IDENTIFY requests
7386 before sending it to the router. Saves some time.
7388 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Fixed JOIN command on client library. Wrong number of arguments
7391 used to crash the client.
7393 * Added silc_server_channel_has_global function to check whether
7394 channel has global users or not.
7396 * Added silc_server_channel_has_local function to check whether channel
7397 has locally connected clients on the channel.
7399 * The silc_server_remove_from_one_channel now checks whether the
7400 channel has global users or not after given client was removed from
7401 the channel. It also checks whether the channel has local clients
7402 on the channel anymore. If it does not have then the channel entry
7403 is removed as it is not needed anymore.
7405 * The silc_server_notify now checks on JOIN notify whether the joining
7406 client is one of locally connected or global. If it is global then
7407 the channel has now global users on the channel and that is marked
7408 to the channel entry. Also, it now saves the global client to
7409 global list who is joining and JOINs it to the channel. This is
7410 for normal server, that is.
7412 Changed silc_server_send_notify_on_channel,
7413 silc_server_packet_relay_to_channel and
7414 silc_server_packet_send_to_channel check if we are normal server
7415 and client has router set (ie. global client) do not send the
7416 message to that client, as it is already routed to our router.
7418 * Implemented LEAVE notify type handling in silc_server_notify
7421 * Tested LEAVE command in router environment successfully. Tested
7422 with two routers, two servers and two clients.
7426 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7428 * Implemented SIGNOFF notify type handling in silc_server_notify
7431 * silc_server_remove_id now removes the client entry from all channels
7432 it has joined and thusly sends SIGNOFF notify type.
7434 * Rewrote the NAMES list generation in server by removing two excess
7435 loops. The lists are created now inside one loop.
7437 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * silc_server_remove_channel_user checks now also global list
7440 for channel and client.
7442 * silc_server_new_channel_user checks now both local and global
7443 list for channel and client. Fixed a bug in client id decoding.
7444 Used to decode wrong buffer.
7446 * silc_server_channel_message checks now both local and global
7447 list for channel entry.
7449 * Tested channel joining (hence JOIN) in router environment
7450 successfully. Tested with two routers, two servers and two
7453 * Tested channel message sending in router environment successfully.
7455 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Added silc_server_save_channel_key into server.[ch] to save the
7458 received channel key in Channel Key payload processing. It is
7459 also used in JOIN command reply handling.
7461 Equivalent function silc_client_save_channel_key added into
7462 client.[ch] into client library.
7464 * Changed JOIN command reply to send information whether the channel
7465 was created or not (is existing already) and the channel key
7466 payload. Changed protocol specs accordingly.
7468 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7469 the request was sent by ID and not by nickname. Crashed on
7472 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7474 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7475 now correctly save the received data.
7477 * silc_server_free_sock_user_data now notifies routers in the
7478 network about entities leaving the network.
7480 At the same time implemented functions silc_server_remove_id
7481 and silc_server_send_remove_id to receive and send REMOVE_ID
7482 packets. The packet is used to notify routers in the network
7483 about leaving entities. The ID removed will become invalid in
7486 * Added function silc_idlist_del_server into server. Removes and
7487 free's server entry from ID list.
7489 * silc_server_private_message function now checks, if we are router,
7490 that the destination ID really is valid ID, naturally.
7492 * In router when NEW_ID packet is received (for new client) the
7493 hash of the Client ID is saved in the ID Cache but the
7494 client->nickname is set to NULL, instead of putting the hash
7497 IDENTIFY command now also checks that client->nickname must be
7498 valid. If it is not if will request the data from the server who
7499 owns the client. Added new function
7500 silc_server_command_identify_check.
7502 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7503 to set the command to already allocated Command Payload.
7505 * Tested private message sending in router environment with two
7506 routers, two servers and two clients. Fixed minor bugs and now
7509 * Fixed segfault from client's NAMES command. Used to crash if
7512 * Forwarded packets must not be routed even if it is not destined
7513 to the receiver. Changed server code comply with this.
7515 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7517 * Added `require_reverse_mapping' boolean value to ServerParams
7518 structure. If TRUE (not default) the server will require that
7519 the connecting host has fully qualified domain name.
7521 If the reverse mapping is not required and hostname could not be
7522 found the IP address is used as hostname.
7524 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Implemented version string checking to both client and server.
7527 The check is incomplete currently due to the abnormal version
7528 strings used in development version of SILC.
7530 * Changed all command functions in server to use the new
7533 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Changed char *data to unsigned char *data in ID Cache system to
7536 support binary data as ID Cache data. Changed code to support
7537 binary data in lib/silccore/idcache.c.
7539 * Renamed silc_server_packet_relay_command_reply to
7540 silc_server_command_reply as it is normal packet receiving
7541 function. Rewrote the function to accept command replys for
7542 servers and not only for clients.
7544 * Mark remote router always as registered server if we are connecting
7545 to it. Otherwise, commands sent by the router to us are ignored.
7547 * All ID List find routines now returns the ID Cache Entry pointer
7548 as well if requested.
7550 * WHOIS command works now in router environment, tested with two
7551 routers, two servers and two clients.
7553 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7554 in router environment (as it is almost equivalent to WHOIS) but
7555 hasn't been tested thoroughly. Added new functions:
7557 silc_server_command_identify_parse
7558 silc_server_command_identify_send_reply
7559 silc_server_command_identify_from_client
7560 silc_server_command_identify_from_server
7562 * Disabled route cache adding because adding two different ID's with
7563 same IP replaces the old cache entry thus giving wrong route.
7564 The entry->router->connection is always the fastest route anyway
7565 so route cache may not be needed. Of course, new routes maybe
7566 established after receiving the ID when the entry->router->connection
7567 might not be anymore the most optimal.
7569 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7571 * Add route cache for received ID for fast routing.
7573 * Added silc_server_packet_route to route received packet on router
7574 that is not destined to us.
7576 * Renamed silc_server_get_route to silc_server_route_get.
7578 * Added id_string and id_string_len fields into SilcServer to
7579 include encoded ServerID for fast comparing without excess
7580 encoding of the ID's.
7582 * Cleaned up WHOIS command on server side. Added following static
7585 silc_server_command_whois_parse
7586 silc_server_command_whois_check
7587 silc_server_command_whois_send_reply
7588 silc_server_command_whois_from_client
7589 silc_server_command_whois_from_server
7591 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7592 arguments in command replies. All command functions should be
7593 updated to use this macro.
7595 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Minor typo fixes on command reply handling on server.
7599 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added silc_server_command_add_to_channel internal routine to add
7602 the client to the channel after router has created the channel and
7603 sent command reply to the server.
7605 * Added generic silc_server_send_command to send any command from
7608 * Use static buffer with ID rendering instead of duplicating data.
7610 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Fixed a channel user mode bug when joining to a channel server gave
7613 everybody channel founder rights, oops.
7615 * We mark ourselves as the router of the incoming server connection
7616 if we are router ourselves. This way we can check in some packet
7617 sending functions whether it is locally connected server. For
7618 incoming router connections we put NULL.
7620 * For router sending packets locally means now always sending the
7621 packet cell wide; to local clients and local servers. For normal
7622 server sending packet locally means sending it to only local
7625 * Fixed the JOIN command to really work in router environment. If the
7626 channel is created it is always created by the router. Router is
7627 also responsible of making the initial joining to the channel,
7628 sending JOIN notify to the sending server and distributing
7629 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7630 does not exist server doesn't do anything else but forward the
7631 command to the router which performs everything.
7633 * Added silc_server_send_channel_key function to send the Channel Key
7636 * Added silc_server_create_channel_key to create new channel key. The
7637 channel key is now re-generated everytime someone joins or leaves
7638 a channel, as protocol dictates. Note: channel->key_len is the
7641 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7643 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7644 packet_receive.[ch] to separate packet sending and receiving
7645 routines. The server.[ch] now includes everything else including
7646 actual packet processing (writing and reading data) and other
7649 Renamed silc_server_private_message_send_internal to
7650 silc_server_send_private_message. The routine is still though
7651 used only to relay private messages as server does not send
7652 private messages itself.
7654 Renamed silc_server_new_channel to silc_server_create_new_channel
7655 and added new function sicl_server_new_channel that handles the
7656 incoming New Channel packet. Added also new sending function
7657 silc_server_send_new_channel to send New Channel Payload.
7659 * Added new function silc_server_notify to process incoming notify
7660 packet to the server/router. Server may then relay the notify
7661 to clients if needed.
7663 * Added new function silc_server_new_channel_user to process incoming
7664 New Channel User packet. Router will redistribute the packet and
7665 send JOIN notify to its local clients and locally connected servers
7666 if needed. Normal server will send JOIN notify to its local client
7667 on same channel when received this packet. Added also corresponding
7668 sending function silc_server_send_new_channel_user to sent the
7671 * Added boolean route argument to send_notif_to_channel and
7672 packet_send_to_channel functions to attempt to route the packet
7673 if it is TRUE and send only locally if it is FALSE.
7675 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * silc_server_replace_id now broadcasts the received replace ID
7678 packet if it is not broadcast packet already. The router must
7679 broadcast to inform other routers about changed ID.
7681 * Added backpointer to server's router into SilcServer context in
7682 silcd/server_internal.h.
7684 * Fixed silc_server_packet_broadcast to send correct broadcast
7687 * The channel key is now distributed to the local client as soon
7688 as it is received from the router (in router environment) so that
7689 no other packet may be sent for the channel until client has
7692 * silc_server_remove_channel_user now broadcasts the received
7693 Remove Channel User packet if it is not broadcast packet already.
7694 The router must broadcast to inform other routers about removed
7697 * Added users field into SilcPacketContext that is a reference count
7698 of the context. One can increase the reference count by calling
7699 silc_packet_context_dup which is now changed to just increase the
7700 reference count instead of duplicating the data. The reference
7701 count is decresed by calling silc_packet_context_free that will
7702 free the data after the reference count hits zero.
7704 For now on the packet context and everything allocated into it
7705 (including the raw packet from network) must be freed by calling
7706 the new silc_packet_context_free function. Added also new function
7707 silc_packet_context_alloc that must be used now to allocate the
7708 context. This also means that if a routine is asynchronous from
7709 silc_[client/server]_packet_parse_type the packet context must
7710 be duplicated by calling silc_packet_context_dup. Otherwise it
7711 gets free'd after silc_[client/server]_packet_parse_type returns.
7712 Also, one must remember that if packet is duplicated then its
7713 reference count must be decresed by calling the free function as
7714 many times as it was duplicated.
7716 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7717 from both client and server.
7719 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Made joining to a channel working in router environment.
7723 * Cleaned up JOIN command on server side and create function
7724 silc_server_command_join_channel internal routine to make the
7727 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7729 * Changed silc_command_pending list to SilcDList. Also, added
7730 `ident' field to SilcServerCommandPending structure to identify
7731 the reply and to call correct callback.
7733 Added silc_server_command_pending_check function to replace the
7734 corresnponding macro. The silc_command_pending list is not
7737 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7738 to set identifier to previously allocated Command Payload. It
7739 is used to set identifier for command when resending Command
7742 * Added silc_command_payload_encode_payload to encode Command
7743 Payload buffer from SilcCommandPayload structure.
7745 * Added silc_argument_payload_encode_payload to encode Argument
7746 payload buffer from SilcArgumentPayload structure.
7748 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Changed WHOIS command to support router connection on server side.
7751 The whois request is always sent to router unless the server is
7752 standalone server. After server has received the reply from the
7753 router will it send the reply to the client.
7755 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7756 broadcast received broadcast packet. The function is used only
7757 by router. The broadcast packet is always sent to the router's
7760 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7761 render given ID to printable string, for log files for example.
7763 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7765 * Made basic router to router connections working. At least they
7766 can now connect to each other but nothing really works the way
7767 they are supposed - yet.
7769 * Added new initiator token to RouterConnection configuration
7770 file in silcd/serverconfig.[ch]. It is used to tell whether we
7771 are the initiator to the remote router or whether we'll expect
7772 the other end to connect.
7774 * Moved registering of listener task to silc_server_init, hence
7775 the server starts listenning as soon as it is run, even if it
7776 does not have connections to other routers. Let's see how well
7779 * Changed default connection retry timeouts for more suitable in
7782 * Removed cipher and such arguments from silc_idlist_add_client
7783 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7784 Added new function silc_idlist_add_data to add the keys and stuff
7787 * Added SilcIDListData structure and added it to SilcClientEntry
7788 and SilcServerEntry as their first field in the structure. This
7789 way we can explicitly cast the ID entries to the SilcIDListData
7790 structure and get common data for the entries. In past, we had
7791 to first check what type of connection it is and then cast it to
7792 correct ID entry type. Now, we can directly cast the opaque
7793 pointer to the SilcIDListData (no matter what ID entry it actually
7794 is) and get the data needed.
7796 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7798 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7799 in some circumstances even if threre were timeout tasks, though not
7800 IO tasks, but tasks anyway. Now fixed.
7802 * Defined SilcServerConnection structure to hold connection specific
7803 stuff about directly connected servers and routers. The definition
7804 is currently in silcd/server_internal.h. I thought about having
7805 a bit more important role fro this struct but for now it is used
7806 only when connecting to other server (or router actually).
7808 * Added connecting retry support in server when connecting to
7809 router(s). The retry feature implement exponential backoff
7810 algorithm. Also, added SilcServerParams structure to hold default
7811 parameters for server. For now, it include these retry settings
7812 and are hard coded. After server is moded to be as Silc Server
7813 Library this structure will be more important.
7815 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Changed client librarys channel->clients table to SilcList and
7818 changed code accordingly.
7820 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * Changed client's channel table to SilcList and changed code
7823 accordingly. Also changed SilcChannelClientEntry to include back-
7824 pointer to the channel so that client entry can use that structure
7825 as list as well and we have fast cross-reference to the channel.
7826 This change dramatically decreased the complexity of channel
7827 handling with client entry and vice versa (removed one extra
7828 loop when searching for channel entry from many functions).
7830 * Changed server->sim from table to SilcDList and changed code
7833 * NAMES command can now be used from user interface. It will show
7834 the user list on the channel, neatly.
7836 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7837 Code now saves realname of the user if it becomes available.
7839 * Renamed configure.in to configure.in.pre and made ./prepare
7840 script to automatically add correct version string to
7841 configure.in which it creates from configure.in.pre.
7843 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * NAMES command reply now shows users mode with the nickname when
7848 * Moved silc_client_ch[u]mode[_char] functions from
7849 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7850 place sucks, they are utility functions and should be in some
7853 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7855 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7858 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Added TRQ (efficient deque and list library) into lib/trq. This is
7863 a very good list library that is currently used in the SILC. Defined
7864 SilcList API over the library because I didn't like the API very
7865 much. See lib/trq/silclist.h for the API and examples of how to
7866 use the API. Fixed various places in the code to use the new
7867 SilcList API. The SilcList is meant for lists that has a structure
7868 already defined as a list. It is not suitable to add just some
7869 context to the list (in TRQ, the context is the list actually).
7871 So, I defined SilcDList that can be used for the purpose where
7872 predefined list structure does not exit. This can be used as
7873 such list. Now some context just can be added to the SilcDList.
7874 Currently this list is not used in the SILC just yet, though there
7875 are a lot places where this can replace dynamically allocated
7876 tables and I will fix these places, later, to use SilcDList.
7877 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7878 and use TRQ internally).
7880 Also fixed some annoying warning messages that the original TRQ
7881 code generated. Also minor changes to TRQ's Makefile.in.
7883 * Added support for querying by Client ID to both WHOIS and
7884 IDENTIFY commands into server, as required by the protocol.
7886 * Removed method function pointers from SilcBuffer structure. They
7887 weren't used to anything and just increased the context size for
7888 no good reason. This change also made silc_buffer_alloc and
7889 silc_buffer_free functions inline functions.
7891 * Disabled command flooding detection support until it's fixed so
7892 that it accepts commands in but does not execute them more than once
7895 * Added silc_net_localhost(), to return local hostname, into
7896 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7897 that must be initialized before calling silc_client_init.
7899 * Added new function: silc_server_send_notify_on_channels to send
7900 notify messages to all channels client has joined. It is assured
7901 that the message is sent only once per client.
7903 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7904 lib/silcutil/silcutil.[ch] as silc_format function. The new
7905 function is generic and is used by server as well, not only by
7906 the logging routines.
7908 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7909 the provided version string was not acceptable. Added new function:
7910 silc_ske_check_version into lib/silcske/silcske.h. The function
7911 must be implemented by the application (client or server) and it
7912 does not reside in the SKE library. The function checks the version
7913 string remote end sent.
7915 * Added back pointers (to opaque context and to SilcSocketConnection)
7916 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7918 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7919 duplicate packet context structure.
7921 * Changed `notify' client operation to send same arguments as client
7922 receives from server except for ID's. ID's are mapped to correct
7923 ID entry and that is returned. Also, if channel entry is not sent
7924 by server but the notify is for channel the channel entry is sent
7925 to application (otherwise application doesn't know that it is for
7926 channel (library gets it from packet's Destination ID)).
7928 * Added silc_client_remove_from_channels into client library to
7929 remove a client from all channels it has joined to. Used when
7930 received SIGNOFF notify from server. Added also new function
7931 silc_client_replace_from_channels to replace old ID entry with
7932 new ID entry on all channels. Used when received NICK_CHANGE
7935 * Fixed ID Cache list handling in silc_idlist_get_client in
7936 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7937 to get (or query) client by ID.
7939 * Updated TODO list.
7941 * Added connection authentication status message defined by the
7942 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7943 support for these into the code in client and server side.
7945 * Added generic function silc_client_send_command to send any command
7946 with variable argument list. Application should use this function
7947 to send commands if the command functions provided by the library
7948 does not suite for the application's user interface needs.
7950 * Added new `failure' client operation. Application is notified about
7951 received failure packet if client is executing a protocol. In this
7952 case the protocol's execution has failed.
7954 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7955 is required by the protocol.
7957 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7958 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7961 * Added status flag to SilcSKE object to indicate realtime status
7962 of the SKE protocol.
7964 * Application receives now exactly same command reply arguments as
7965 the library receives from server. However, if ID is received the
7966 corresponding ID entry is returned to the application (eg. Client
7967 ID is mapped to correct SilcClientEntry entry and that is returned).
7968 Changed command_reply client operation due to this change.
7970 * Changed all ID's in commands and in command replys as ID Payloads.
7971 Change affected both client and server side codes.
7973 All ID's sent in SILC network (with execption of ID's in SILC
7974 Packet header) are sent in ID Payload to support variable length
7977 * Server now notifies nick changes and notifies all clients on
7978 the channels about the new nickname (about the new Client ID,
7981 * Implemented CMODE command to change channel modes. Supports all
7982 channel modes defined by the protocol specs except ban and invite
7983 lists. (Also, private channel key mode is supported but support for
7984 setting private channel key in client is missing, thus, this mode
7985 has no effect on client side (except that server requires that the
7986 client uses private channel key and normal channel traffic does not
7989 Also, invite mode works per se, but INVITE command does not work
7990 yet correctly, so you can set channel as invite only channel but
7991 inviting clients to the channel does not work (it is yet to be
7992 thought what's the best way to do it).
7994 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7995 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7996 Implemented CUMODE command to change user's mode on the channel.
7997 Supports all modes defined by the protocol specs.
7999 * Added NAMES command reply to return users modes on the channel.
8001 * Removed unnecessary and slow ciphers from lib/silccrypt.
8003 * Set SO_KEEPALIVE option to connection sockets by default.
8005 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8007 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8008 redefined the Notify Payload into protocol specs.
8010 * Added silc_id_payload_parse_id to get ID directly from raw
8013 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8016 accept searching by Client ID as well.
8018 * Added support for LEAVE and SIGNOFF notify types in client library.
8020 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8021 to parse ID Payload from raw data.
8023 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8025 * Added flags parameter into silc_ske_assemble_security_properties
8026 function in lib/silcske/silcske.[ch].
8028 * Changed notify client operation to fit better for notify messages
8029 sent by server. The notify payload received from server is now
8030 passed to the application (after parsing it to SilcNotifyPayload).
8031 It is application's responsibility to retrieve the arguments
8032 from the payload and show the message the way it wants. The message
8033 sent by server is implementation specific.
8035 * Changed public keys to comply with the protocol specification.
8036 Old public keys are not supported anymore and are not compatible.
8038 * Removed nickname from Channel Payload as the latest draft removed
8039 it. The client must resolve the nickname from the NAMES command
8040 reply received when it joined the channel.
8042 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8044 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Fixed some errors in protocol specification drafts.
8048 * Created lib/silccore/silcnotify.c to implement Notify Payload
8049 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8050 generic payloads described by protocol specifications. The file
8051 includes implementations for ID Payload and Argument Payload.
8053 * Changed Command Payload implementation to use the new Argument
8054 Payload. Changed command_xxxx_payload to command_payload_xxxx
8055 to comply with SILC coding conventions.
8057 * Added suppport for Argument Payload handling in Notify Payload
8058 implementation as protocol requires it. Added the new support
8059 into server and client lib as well.
8061 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8063 * Added support for multiple nicknames on same channel. [n] is
8064 added locally to the nickname if there are more than one same
8065 nicknames on the channel.
8067 * Server now sends all nicknames that matched WHOIS request.
8068 Client also shows the list received from server.
8070 * Added TOPIC command to client side. User can now set and show
8071 current topic on channel.
8073 * Added MOTD command to client and server. Also, server sends the
8074 motd when client connects to the server.
8076 * Changed version strings to comply ISO 8601.
8078 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Fixed protocol error handling in client library. It should now
8081 cope even if the SKE fails for some reason.
8083 * Made new protocol specification drafts for submitting to IETF.
8085 * Implemented TOPIC command to server in silcd/command.c.
8087 * Added two new notify types into lib/silccore/silcnotify.h:
8088 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8089 notify nickname change and topic setting/change on a channel.
8091 * API change of command_reply operation in client library. The
8092 application gets now the status type received from server as well.
8094 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8098 * Cras fixed and optimized the packet handling even further and
8099 it should work now. Minor change to the prototype of function
8100 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8102 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Added new function into lib/silcutil/silcschedule.[ch]:
8105 silc_schedule_with_fd to select() a specified fd. The function
8106 returns after timeout expires or data arrives or goes. The
8107 function is used by packet routines to wait that all data is
8108 received from network.
8110 * Fixed data reading from network in lib/silccore/silcpacket.c.
8111 The code now assures that all data is read from the fd and then
8112 continues packet processing. This was a bug fix since the code
8113 used to drop some data in some circumstances.
8115 * Added new function into lib/silcclient/client.[ch]:
8116 silc_client_start_key_exchange to start key exchange after
8117 connection has been established to server. The code internally
8118 now uses this funtion but its main purpose was to provide it
8119 for applications that perform their own connecting. After
8120 application has created a connection it merely calls this
8121 function to start the key exchange between client and server.
8122 The library takes care of everything else after that.
8124 Updated also lib/silcclient/README to explain the usage of
8127 * Do not send to application information that connection has
8128 been established. Application gets notified it by connect
8131 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Applied cras's patch to add silc_schedule_one function. The
8134 function runs scheduler once and returns.
8136 * Fixed the scheduler after cras messed it up. The timeout
8137 handling works now as it's supposed to work.
8139 * Added into lib/silccore/ silcnotify.h to include notify
8140 message types support. Changed silc_server_send_notify*
8141 functions, in server.[ch], to support those new notify types.
8142 Added the support for the notify types into client library,
8143 as well. Added new notify client operation into ops.h in
8146 * Changed silc_server_packet_send_to_channel to send normal
8147 packets instead of just channel message packets. The function
8148 is now used to send the notify packets to channels. It is not
8149 used to send channel message packets anymore, as server never
8152 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8153 va_arg()s as it seems to require it nowadays. I guess, if SILC
8154 is compiled with older va_arg() the new code should work anyway.
8156 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Splitted core library. Core library (lib/silccore) includes
8159 now only SILC protocol specific core (and common) components.
8160 Created new utility library (lib/silcutil) that includes more
8161 generic purpose stuff. The stuff for util library was taken
8162 from the old core library. This was minor and easy split.
8164 * Created SILC Client Library (lib/silcclient) that includes
8165 implementation of the SILC client without user interface. This
8166 was major move from silc/ directory. The code has been changed
8167 so that it is transparent towards the user interface. The
8168 silc/ directory includes now the same user interface as before
8169 and it uses the new client library. Read lib/silcclient/README.
8170 Basicly, the client library performs everything else related
8171 to SILC except user interface handling. Also, configuration
8172 files are considered to be part of user interface and library
8173 does not handle them.
8175 This change also changed a lot of structures, function naming etc.
8176 Most important change was that SilcClientWindow object was
8177 renamed to SilcClientConnection in the client library. Created
8178 also new file lib/silcclient/ops.h. Also added new files
8179 silc/local_command.[ch] and silc/client_ops.[ch].
8181 All these changes were made to make it easier for user interface
8182 designers to create what ever user interface for the SILC client
8185 It is also expected that the server will be moved to lib
8186 directory as well and SILC Server Library will be created;
8187 sometimes in the future.
8189 * Removed Local commands from lib/silccore/silccommand.h as
8190 they are application specific and new client library does not
8191 handle any of those anymore.
8193 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8194 old client implementation in silc/.
8196 * Added support for callback functions in SILC_LOG_* macros.
8197 Application can now set its own callbacks that will be called
8198 instead of using the default functions that will always print
8199 the debug messages to stderr (or stdout). Also, debugging can
8200 now be disabled by setting silc_debug to FALSE and re-enabled by
8201 setting it to TRUE. Note, that logging will still work even
8202 if debugging is disabled.
8204 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8205 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8206 silc_log_reset_debug_callbacks.
8208 * To enable debugging in silc client one must give now -d
8209 option on command line.
8211 * Changed silc_schedule_init to automatically allocate task queues
8212 if they are not allocated before calling it.
8214 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Added GMP 3.1 into math library.
8218 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8221 a channel in SILC network. The packet is used by servers and
8222 routers to notify other routers that user has left a channel.
8223 This little feature was missing until now. Added the feature
8224 to protocol specification as well.
8226 Added functions: silc_server_send_remove_channel_user and
8227 silc_server_remove_channel_user into server.[ch].
8229 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8230 lib/silccore/silcpacket.h. However, they are not implemented
8233 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8235 * Fixed joining to a channel and sending channel messages
8236 between server and router. The channel message sending should
8237 now work inside a cell.
8239 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8241 * Fixed the private message sending between server and router.
8242 The private message sending should now work inside a cell.
8244 * Added silc_server_replace_id into server.[ch] to replace
8245 existing ID in the SILC network.
8247 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8248 and silc_idlist_replace_server_id into idlist.[ch] in server.
8250 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8252 * Fixed the server to server connections. Server can again now
8253 connect to router. Router to router connections probably does
8256 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8258 * Added dynamic protocol registering support. Now protocols can
8259 registered and unregistered on the fly. Patch by cras.
8261 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added lib/contrib directory to hold routines that some platforms
8264 don't have but are needed by SILC.
8266 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8267 into lin/contrib to provide getopt() and getopt_long() for
8268 those who don't have it.
8270 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8272 * Added AWAY command to client. When away message is set and
8273 client receives a private message packet the client automatically
8274 replies to the sender with the away message.
8276 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8277 bug seemed to be the cause of recent problems when compiling
8280 * Added version detection support to SKE protocol specification
8281 and added the new changes to the SKE implementation as well.
8282 There were other minor changes in the SKE protocol as well.
8284 Many changes in lib/silcske/silcske.[ch] and in
8285 lib/silcske/payload.[ch].
8287 * Added ^U functionality, clear input line. Patch from cras.
8289 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8291 * Mainly small bugfixes on core library. Fixed some debugging
8292 logging and buffer overflow in silclog.c.
8294 * Updated config.sub and config.guess on the distribution tree.
8296 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8298 * Added command lagging support in server. Client may execute
8299 commands now only once in two seconds.
8301 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8303 * Optimized packet reception. MAC computation and checking is now
8304 also more optimized. A lot previously duplicated code is now
8305 used as generic by both client and server.
8307 * Fixed key pair generation in clientutil.c
8309 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8311 * Added into lib/silccore/silcbufutil.[ch] new function;
8312 silc_buffer_realloc.
8314 * Moved generic packet sending/encryption functions to
8315 lib/silccore/silcpacket.[ch] from client and server. Some
8316 rewriting of the functions.
8318 * Moved all generic packet reception/decryption functions to
8319 lib/silccore/silcpacket.[ch] from client and server. The
8320 packet processing is now much cleaner in both client and server.
8321 These were major changes in both client and server.
8323 * Created many common functions in server to do packet sending.
8324 Previously code were duplicated a lot, this has been removed
8327 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8329 * Rewrote major parts of the ID cache system. Don't know
8330 whether it is better now or not but at least the API is more
8333 * Major rewrite on ID cache stuff on client because of the ID
8334 cache API changes. Added idlist.c to client.
8336 * Also major rewrite on ID cache stuff on server as well.
8337 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8338 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8339 in hand, instead they are all put into the ID cache system now.
8340 All server_idlist_* routines uses ID cache now instead of
8341 traversing its own lists (those lists does not exist anymore).
8342 SilcIDList though still exists. Also, SilcXXXEntry's are
8345 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * Finally made the SKE implementation compliant to the protocol
8348 specification. All mp integers are now binary encoded as
8349 opposed being HEX encoded.
8351 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8354 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8355 functions: silc_[encode/decode]_pem. Also added function
8356 silc_encode_pem_file to PEM encode with newlines ('\n') for
8359 * SILC public keys are now encoded either PEM or binary. Same
8360 option is for private keys as well. By default private keys
8361 are binary encoded and public keys PEM encoded. Silly HEX
8362 encoding were removed.
8364 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8365 function to create fingerprints.
8367 * Fixed a bug in SHA1; does not change the original data anymore.
8369 * Partly implemented INFO command on client and server side.
8370 Fixed CLEAR command. Changes to SERVER command; show current
8371 server(s) when giving command without arguments. Added
8372 VERSION command to client.
8374 * Added check to server that unregistered connections cannot
8375 execute commands (unless it is specificly allowed).
8377 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8379 * Fixed screen refresh.
8381 * Fixed channel joining bug from client. On some circumstances
8382 client tried to join to a channel it had already joined.
8384 * Added public key verification process into client's protocol.c.
8385 The client now verifies the public key from user and saves
8386 it into ~./silc/serverkeys/ directory.
8388 Added into: clientutil.[ch]: silc_client_verify_server_key.
8390 * Changed SKE protocol's silc_ske_initiator_finish function
8391 to accept callback function that verifies the received public
8392 key. Removed old silc_ske_verify_public_key function.
8394 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8396 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8397 silc_pkcs_private_key[_data]_set.
8399 * Made the password and public authentication more cleaner in
8400 server's protocol.c.
8402 * Removed historic and obsolete protocol `channel_auth' from
8403 both client and server.
8405 * Removed wrong way of sending command status messages from
8406 server to client in server's command.c. The old way violated
8407 protocol specification.
8409 Changes to silccore/silccommand.[ch]: removed
8410 silc_command_encode_status_payload -> not needed anymore,
8411 changed silc_command_encode_payload_va to accept extra
8412 argument on variable argument list. The argument type must
8413 now be provided to the function. Also, added new function:
8414 silc_command_encode_reply_payload_va which is same as
8415 normal command_encode_payload_va except command status type
8416 is provided as extra argument.
8418 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Added ~./silc directory handling. The directory includes the
8421 public and private keys for the client.
8423 Added silc_client_check_silc_dir, silc_client_create_identifier
8424 and silc_client_load_keys.
8426 * Implemented SILC protocol compliant public key. Added public
8427 and private key saving to and loading from files.
8429 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8430 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8431 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8432 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8433 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8435 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8436 silc_pkcs_load_[public/private]_key.
8438 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8440 * Added silc_server_get_route (route.[ch]) to get connection
8441 data for the fastest route for given ID.
8443 * Implemented INVITE command on client and server. The command
8444 were re-defined in the SILC Protocol Specification and the
8445 implementation now complies with the specification.
8447 * Implemented PING command on client and server.
8449 * Implemented NAMES command on client and server. The server side
8450 supports currently only normal server not router server yet.
8451 Some changes to NAMES definition in SILC protocol specification.
8453 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8455 * Implemented LEAVE command on client and server.
8457 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8458 again. This change was made to the protocol as well. Server
8459 should not violate the protocol specification anymore.
8461 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8463 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8464 was tested. SOCKS4 was not but should work anyway.
