504 command_reply client operation. Affected file is
505 lib/silcclient/command_reply.c.
507 * Changed the channel message payload's MAC generation to
508 include the IV in the MAC as well. This way all relevant
509 parts of the channel message payload are authenticated also
510 with the channel message MAC (and not only by packet MAC).
511 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
512 Affected file is lib/silccore/silcchannel.c.
514 * Fixed the SKE to save the remote version, since the

536 lib/silcclient/protocol.c, silcd/protocol.c,
537 silcd/serverconfig.c, and lib/silccore/silcauth.c.
539 * Changed the silc_client_close_connection interface to not
540 need the SilcSocketConnection which should not be visible
541 to application. Affected files are lib/silcclient/client.c
542 and lib/silcclient/silcclient.h.
544 * Rewrote the text for Private Message Key Payload in the
545 protocol specification. Protocol TODO #11.
547 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Upgraded the protocol version to 1.1, updated protocol specs
552 * Added the nickname as new argument to NICK_CHANGE notify and
553 added it to protocol specs and implemented it to client and
554 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
555 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
556 lib/silcclient/client_notify.c.

563 The killer's client entry is now returned to application in
564 the `notify' client operation.
566 * Fixed the Max Argument fields that had too large value set
567 in the protocol specs. Protocol TODO #14.
569 * Added the LEAVE command reply to return the ID of parted
570 channel. Updated protocol specs and implemented it to the
571 client and server. Protocol TODO #15. Affected files are
572 silcd/command.c, lib/silcclient/command_reply.c. The channel
573 entry is now returned to application in the `command_reply'
576 * Rewrote the version SKE version checking in client libary
577 and in server to use the silc_parse_version_string. Affected
578 files are lib/silcclient/protocol.c, silcd/protocol.c.
580 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
581 commands that was missing it, and updated protocol specs and
582 the server implementation. Protocol TODO #10. The affected
583 file is silcd/command.c.
585 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
586 generic reply to a generic request (REQUEST flag), and
587 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
588 way. A draft-riikonen-silc-flags-payloads-00.txt is written
589 to define the payload for DATA flag. Added the flags to
590 the implementation. Protocol TODO #9. Affected file is
591 lib/silccore/silcchannel.h.
593 Changed the client library to return the message length
594 to application as well in the channel_message and private_message
595 client operations. Affected files are
596 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
597 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
598 and lib/silcclient/client_ops_example.c.
600 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
601 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
602 the channel. Updated protocol specs and impelemented this
603 to client and server. Protocol TODO #6. Affected files are
604 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

607 Added new options m and M to CMODE command in Irssi SILC
608 client to set these modes.
610 * Deprecated all administrative commands from SILC protocol
611 since they are highly implementation specific commands.
612 Updated protocol specs. Moved the old commands in
613 implementations to private range of command types. Affected
614 files are silcd/command.c, lib/silcclient/command.c and
615 lib/silcclient/command_reply.c. Protocol TODO #8.
617 * Fixed a bug in server where sending unknown command crashes
618 the server. Affected file silcd/command.c.
620 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
622 * Added SILC_PROTOCOLVERSION macro to check protocol version
623 of a socket connection. The affected file is
624 lib/silcutil/silcsockconn.h.

633 Affected file silcd/protocol.c.
635 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Some client implementations quit network by doing first LEAVE
638 and then immediately SIGNOFF (like Bombyx). We now do check
639 after a short time after LEAVE notify and check whether the
640 client is still valid after LEAVE, and if not we remove it from
641 cache. Affected file is lib/silcclient/client_notify.c.
643 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
645 * Merged version 1.1.4 of zlib. Even if it not currently in use,
646 it's good not to have security holes here.
648 * Fixed a negative refcount situtuation for the config context.
649 Affected file is silcd/serverconfig.c.
651 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
653 * ROBOdoc documented lib/silcutil/silcutil.h.
655 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
657 * Optimized even more the SilcPacketContext structure. Now
658 totally saved 16 bytes of memory per context after optimization.
659 Affected files are lib/silccore/silcpacket.[ch].
661 * Made strict checks for valid SILC IDs. Affected file is
662 lib/silccore/silcid.c.
664 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

669 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
671 * Changed the silc_get_username and silc_get_real_name to
672 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
674 * Fixed the Irssi SILC Client to use the silc_get_username and
675 silc_get_real_name insted of glib routines since the glib
676 routines only corrupt stack. Fixes the Irssi SILC to work in
677 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
679 * Fixed the Irssi to not use g_get_home_dir since it crashes
680 or returns garbage on cygwin and corrupts stack. Added function
681 get_home_dir to Irssi routines. Affected files are
682 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
684 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
686 * Made some structure optimizations. SFTP memory FS MemFSEntry
687 entry structure. Optimized SilcTask structure. Optimized
688 SilcPacketContext structure.
690 Affected files lib/silcsftp/sftp_fs_memory.c,
691 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
693 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * And yet again reverted back the config thing since Johnny
696 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
699 * Fixed memory leaks from config object. Affected files are
700 silcd/serverconfig.[ch].
702 * Added support for adding new connections to the server in rehash.
703 After rehash they take effect.
705 Added support for changing the maximum allowed connections in
706 rehash. The number can grow but going smaller is not supported.
708 Added function silc_server_num_sockets_by_remote to the
709 silcd/server_util.[ch].
711 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
713 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
715 * Added preliminary checking during config parsing for a valid
716 public/private key and removed further checks in the code.
717 Affected files are silcd/serverconfig.[ch], server.c.
719 * Moved functions silc_server_drop() and silc_server_daemonise()
720 from server.c to silcd.c since they are stricly related to
721 the application activity.
723 * Reverted a small part of the automatic ref/unref since
724 it caused a double unref in some situations. Affected
725 files are silcd/silcd.[ch], server.c, serverconfig.c.
727 * Added some .cvsignore files in the lib directory.
729 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
731 * Fixed silc_net_gethostbyaddr to correctly resolve by
732 address. Affected file lib/silcutil/silcnet.c.
734 * Fixed the notify relaying to client. The HMAC to be used
735 with relayed packets ws wrong and caused decryption failure
736 at the client end. Affected file is silcd/packet_receive.c.
738 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
740 * Created new branch silc_protocol_1_0_branch.
742 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
744 * Changed the silc_server_config_* routines to be SilcServer
745 independent. They are now officially application specific code
746 and not part of generic server implementation. Affected files
747 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
749 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
751 * Added automatic referencing of config context in the
752 silc_server_config_alloc, and automatic unreferencing in the
753 silc_server_config_destroy. Affected files are
754 silcd/serverconfig.[ch], silcd/silcd.c.
756 * Fixed the silc_log_quick handling in the logging routines.
757 It didn't log quickly when it was TRUE. Affected file is
758 lib/silcutil/silclog.c. Also the flush delay was set even
759 if it was 0 in config file. Affected file is
760 silcd/serverconfig.c.
762 * Added support for changing key pair of the server in rehash.
763 Affected file silcd/server.c.
765 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Fixed the TOPIC_SET notify to not cras. It changed the topic
768 too early, before getting the channel entry. Affected file
769 is silcd/packet_receive.c.
771 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
773 * Added functions silc_server_config_[ref/unref], these are used
774 to prevent that the config object is destroyed.
776 No longer directly affect global variables silc_log_quick and
777 silc_log_delay, they are first cached inside the config object
778 and then applied with silc_server_config_setlogfiles().
780 silc_server_config_set_defaults() is now internal to
781 serverconfig.c, there are no reasons to show this internal stuff
784 Affected files are silcd/serverconfig.[ch].
786 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
787 fprintf's to stderr, since some code may be executed again after
788 the server went into the background. Affected files are
791 * Added rehash support. Added function silc_server_rehash() that
792 will perform all the basic tasks of the rehashing procedure.
794 * Added command line option `-x, --hexdump'. This will enable the
795 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
796 The option `--hexdump' implies `--debug'.
798 * Fixed a bad bug in the logging APIs (silcutil library) where
799 the application would crash after calling silc_log_reset_all().
801 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed the KICKED notify handling in client library to
804 correctly remove the channel and all entries from the
805 channel when I was kicked. This bug crashed the client.
807 Fixed yet another but in KICKED notify handling to remove
808 the kicked client correctly from the channel.
810 Affected file is lib/silcclient/client_notify.c.
812 * Fixed a minor bug in looking up correct client entry
813 in KICKED notify in server. Affected file is
814 silcd/packet_receive.c.
816 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
817 sources correctly to distribution. Fixes --with-gmp option.
819 * Removed the manual rehashing from ID Cache, and changed it
820 to use the SILC Hash Table's auto rehash feature. Affected
821 file is lib/silccore/silcidcache.c.
823 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
825 * Fixed a bug in the silc_client_nickname_format function that
826 handles the multiple same nickname formatting. Two clients
827 with same nickname caused problems after the first one left
828 and rejoined. It didn't format the nickname correctly.
829 Affected file is lib/silcclient/idlist.c.
831 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
833 * Don't change the topic if olod topic is same as new one.
834 Affected file is silcd/packet_receive.c.
836 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Added cross-reference support to the SILC Documentation
839 generator. All types across all HTML files are now cross-
840 referenced. Affected files util/robodoc/generator.c and
841 scripts/silcdoc/silcdoc.
843 * Added file lib/silcutil/silctypes.h to include all the
844 arithmetic type definitions and some macros. Removed
845 includes/bitmove.h and moved macros to silctypes.h.
847 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
849 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
851 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
853 * Added `type' argument to silc_id_payload_parse_id function which
854 now returns the type of the ID to the sent pointer. Affected
855 file is lib/silccore/silcid.[ch].
857 * Added check for CMODE_CHANGE notify type that mode change is
858 allowed by the sender. Affected file silcd/packet_receive.c.
860 * Added check for CUMODE_CHANGE notify type that mode change is
861 allowed by the sender. Affected file silcd/packet_receive.c.
862 Added the ID type as CUMODE_CHANGE notify type as argument
863 to the `notify' client operation. Affected files are
864 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
866 * Added function silc_client_add_server to the client library.
867 Added support for resolving also channel and server info when
868 received unknown entity in notify packet. Affected files are
869 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
871 * Added function silc_command_get_status to return the command
872 status from the command reply's argument payload. Affected files
873 are lib/silccore/silccommand.[ch].
875 * Added check for KICKED notify type that the kicking is
876 allowed by the client. Affected file silcd/packet_receive.c.
878 * Created function silc_get_input which can be used to get input
879 (echo on or off) from user on command line. Affected files are
880 lib/silcutil/silcutil.[ch].
882 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
884 * Optimized silc_server_packet_relay_to_channel function.
885 Added new function silc_channel_message_payload_encrypt which
886 can be called directly if channel message payload needs to
887 be encrypted and is already encoded (no need to call _encode
888 function). Packet relaying is now done by router without any
889 extra memory allocations. Affected files are
890 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
893 * Fixed the INVITE notify handling. It took wrong arguments
894 as invite list and invite delete. Affected file is
895 silcd/packet_receive.c.
897 * Added check for TOPIC_SET notify type that the topic change is
898 allowed by the client. Affected file silcd/packet_receive.c.

906 Affected files are silcd/server_util.[ch], silcd/command.c.
908 * Added function silc_server_check_umode_rights to check whether
909 changing client's user mode is allowed. Added check for
910 UMODE_CHANGE notify type that the umode change is allowed
911 by the client. Affected files are silcd/server_util.[ch],
912 silcd/packet_receive.c and silcd/command.c.
914 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
916 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
917 ID length. It ignored that ID can be IPv6 based as well.
918 Affected file lib/silccore/silcpacket.h.
920 * Fixed the silc_id_id2str and silc_id_str2id to take the
921 IPv6 address offset's into consideration. Affecte file is
922 lib/silccore/silcid.c.
924 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Fixed the internal Unix scheduler functions to check for
927 NULL context they may receive. The affected file is
928 lib/silcutil/unix/silcunixschedule.c.
930 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
932 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
933 can specify different directory with --home command line
934 parameter. Affected files irssi/src/silc/core/client_ops.c,
937 * SILC-specific commands aren't now executed if the active server
938 isn't of SILC-type, so there won't be problems with having
939 IRC and SILC protocol support in same client. Affected files
940 irssi/src/silc/core/silc-channels.c, silc-servers.c,
943 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Improved the signal support in SILC Schedule. Added new
946 function silc_schedule_signal_call which is used by application
947 to mark a signal to be called. It is now safe to perform
948 any kind of tasks in signal callbacks since it is guaranteed
949 that the application specified signal callback is called
950 after the signal is over. Affected files are
951 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
953 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Added `name' field to SilcChannelPrivateKey to represent
956 application given name for the key. Moved also the context from
957 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
958 Added the `name' argument also to the function
959 silc_client_add_channel_private_key.
961 Added function silc_client_current_channel_private_key to set the
962 current channel private key in use.
964 Added "change" command to KEY command which can be used to change
965 the current channel private key. Bound the command also to
968 Also affected files lib/silcclient/client_channel.c,
969 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
971 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Added silc_rng_get_byte_fast function in to the
974 lib/silccrypt/silcrng.[ch].
976 * Changed the interface of silc_packet_assemble and the
977 silc_packet_send_prepare. If silc_packet_assmble is now
978 called the application does not call silc_packet_send_prepare
979 because the library will call it automatically. These
980 interfaces now also return a reference to the outgoing buffer
981 which includes the assembled packet, which the application can
982 use to encrypt the packet.
984 Affected files are lib/silccore/silcpacket.[ch],
985 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
986 silcd/packet_send.c, server_backup.c and packet_receive.c.
988 * Fixed a packet sending bug on very high load, where outgoing
989 packet queue wasn't handled correctly and packets got corrupted.
990 Affected files are lib/silcutil/*/silc*sockconn.c,
991 lib/silcclient/client.c and silcd/server.c.
993 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Added macro SILC_PACKET_DATALEN which can be used during
996 packet assembling to check whether the data to be added to
997 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
998 len is truncated until it fits it.
1000 Added checks for maximum length of channel message payload and
1001 private message payload also.
1003 Added checks for maximum packet length in server and in
1006 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1007 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1008 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1009 lib/silcclient/client_prvmsg.c.
1011 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1013 * Added silc_server_packet_queue_purge call to the
1014 silc_server_disconnect_remote to assure that all data in the
1015 queue before disconnecting is sent to the network. Affected
1016 file silcd/server.c.
1018 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Added the deleting of server's own ID cache entry to the
1021 silc_server_free function. Free also everything else that
1022 has been allocated in silc_server_init. The affected file
1025 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Added functions silc_parse_version_string, silc_version_to_num,
1028 and silc_ske_parse_version to parse SILC protocol style version
1029 strings. Affected files lib/silcutil/silcutil.[ch] and
1030 lib/silcske/silcske.[ch].
1032 * Added new configuration params: version_protocol, version_software
1033 and version_software_vendor to specify what version the remote
1034 host must at least be to be able to connect to server. The vendor
1035 string can be regex matched too. Added new function
1036 silc_server_connection_allowed to check maximum number of allowed
1037 connections, and allowed versions for incoming connections.
1038 Affected files are silcd/server.c, server_util.[ch] and
1041 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1043 * Added preliminary support for signals in scheduler. The
1044 signals we care about are now blocked always when the scheduler
1045 is locked. This way we can synchronise the use of signal with
1046 scheduler. It is guaranteed that when signal occurs the scheduler
1047 is not locked, and thus new tasks can be safely added to the
1050 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1051 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1052 Added new platform specific routines
1053 silc_schedule_internal_signals_[un]block and
1054 silc_schedule_internal_signal_[un]register.
1056 Added new functions to SILC Schedule API:
1057 silc_schedule_signal_[un]register. Each signal that application
1058 is going to use should be registered to the scheduler.
1060 Affected files are lib/silcutil/silcschedule.[ch],
1061 lib/silcutil/*/silc*schedule.c.
1063 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1065 * Check for unauthenticated client and server in the
1066 silc_server_new_client and silc_server_new_server functions.
1067 Affected file silcd/packet_receive.c.
1069 * Added function silc_string_is_ascii to check whether given
1070 string is 7-bit ASCII string. Affected files are
1071 lib/silcutil/silcutil.[ch].
1073 * Added function silc_id_is_valid_server_id into the
1074 silcd/serverid.c and added checking for valid Server ID's in
1075 silc_server_new_server. The Server ID must always be based
1076 on the server's public IP address.
1078 * Added logging of DISCONNECT packet message in the server.
1079 Affected file silcd/server.c.
1081 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1083 * Changed all library interfaces that use Global RNG to also
1084 accept SilcRng as argument. Affected files are
1085 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1086 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1087 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1088 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1089 lib/silccrypt/rsa.c.
1091 * Added function silc_pkcs_generate_key to the
1092 lib/silccrypt/silcpkcs.[ch] for applications so that they
1093 don't need to do pkcs->pkcs->init calls anymore.
1095 * Remove SilcSocketConnection from the SFTP API since it really
1096 wasn't needed there. The application has the information
1097 saved in its contexts anyway and the SFTP layer doesn't need
1098 know about it. Affected files lib/silcsft/silcsftp.h and
1099 lib/silcsftp/sftp_[server/client].c.
1101 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1102 The SilcSimContext is not SilcSim.
1104 * Fixed possible buffer overflows in silc_id_render in the
1105 lib/silcutil/silcutil.c.
1107 * On EPOC the global crypto module lists are not used at all
1108 in the crypto library. Added support for using the constant
1109 algorithm list on EPOC. Affected files are
1110 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1113 * Fixed the handling of third parameter of KICKED notify, since
1114 it was mistakenly updated to SILC Protocol 1.0 even though it
1115 is to be included in 1.1. Since it is not in 1.0 it is not
1116 mandatory, and this fix now handles it only if it is provided,
1117 and it is not error if it is not provided. Affected file
1118 lib/silcclient/client_notify.c.
1120 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1122 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1123 client. Affected file irssi/src/silc/core/client_ops.c.
1125 * Merged with Irssi 0.8.4 from irssi.org CVS.
1127 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1129 * Check for valid socket connection in client entries before
1130 sending any messages. Fixes a crash, but doesn't fix some
1131 other underlaying bug that is lurking there. Affected
1132 file silcd/packet_send.c.
1134 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1136 * $usermode, $cumode and $cumode_space expandos shouldn't do
1137 anything with non-SILC server records. Affected file
1138 irssi/src/silc/core/silc-expandos.c
1140 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1142 * Fixed the silc_net_check_[host/local]_by_sock to support
1143 IPv6 bound sockets as well. Now they can return IPv6 addresses
1144 as well. Affected file lib/silcutil/silcnet.c.
1146 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1147 Affected lib/silcutil/unix/silcunixnet.c.
1149 * Fixed ID rendering (at least on some platforms, not NetBSD)
1150 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1152 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1154 * Added silc_hash_public_key and silc_hash_public_key_compare
1155 functions to be used with SilcHashTable. They can be used to
1156 hash public keys and compare public keys in hash table. Affected
1157 file lib/silcutil/silcutil.[ch].
1159 * Added support for specifying multiple public keys for Client
1160 connection section in server configuration file. This makes it
1161 possible to accept multiple public keys from same host, or to
1162 make a section that accepts any incoming host, and have the
1163 accepted public keys listed in the section.
1165 Added functions silc_sever_[find/get]_public_key, added the
1166 support for this actually to all connection sections but only
1167 the Client section is currently allowed to specify multiple
1170 Affected files are silcd/server.c, server_internal.h,
1171 command.c, protocol.c, server_util.[ch], packet_receive.c.
1173 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1175 * Merged Irssi 0.8.2 from irssi.org CVS.
1177 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1179 * If silc_debug is TRUE, also output standard logging messages
1180 to stderr with the debug output.
1182 Made silc_log_reset_all() flushing all channels before returning.
1183 Also fixed some documentation typos.
1185 Affected files are lib/silcutil/silclog.[ch].
1187 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Fixed the server to check correctly the amount of connections
1190 from single host, by checking also the type of the connection.
1191 Fixed also the comparison of number of connections and number
1192 of allowed connections. Affected files are silcd/server.c,
1195 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Fixed the USERS command reply to save the user's mode on the
1198 channel as well. Fixed JOIN command reply to check whether a
1199 client is on channel already and not join it twice. Affected
1200 file lib/silcclient/command_reply.c.
1202 * Added new file silc-expandos.c into irssi/silc/core/ to return
1203 various stuff for various signal for the statusbar etc. updating.
1204 Now Irssi SILC client prints channel user modes etc. on the
1207 * The user mode (like server/router operator changes) is now shown
1208 on the Irssi SILC client's statusbar. The affected files are
1209 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1211 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1213 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1214 to SILC_SCHEDULE_[UN]LOCK macros.
1216 * Added more error printing to logs in server code. Affected
1217 files silcd/server.c and silcd/protocol.c.
1219 * Fixed -S option parsing in Irssi SILC Client. Affected file
1220 irssi/src/silc/core/silc-core.c.
1222 * Added silc_buffer_alloc_size function. Affected file is

1237 * Fixed the buffer formatting and unformatting routines to
1238 check the size of 64 bits types with sizeof(). Affected
1239 file is lib/silcutil/silcbuffmt.c.
1241 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1245 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1247 * Changed all integer type names:
1248 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1249 to avoid collisions with other libraries using same type names
1252 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1254 * Added `prefer_ipv6' argument to the functions
1255 silc_net_gethostbyname[_async]. If it is TRUE it will return
1256 IPv6 address over IPv4. If FALSE IPv4 address is returned
1257 even if IPv6 address was found. Affected files
1258 lib/silcutil/silcnet.[ch].
1260 * Added support silc_net_create_connection[_async] to fallback
1261 to IPv4 address if IPv6 address could not be used (like if
1262 it doesn't work on a specific system). Affected file in
1263 lib/silcutil/unix/silcunixnet.c.
1265 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1267 * Added silc_schedule_reinit function to do the enlarging
1268 of the max tasks handling capabilities of the scheduler.
1269 Affected files lib/silcutil/silcschedule.[ch].
1271 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Added automatic extern "C" { ... } for C++ compilers so the
1274 application does not need to define them. Affected file
1275 includes/silcincludes.h.
1277 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1278 old name went against naming convention. Applications now
1279 include "silcclient.h" instead of "clientlibincludes.h".
1280 Removed includes/clientlibincludes.h, it is redundant now.
1282 * Renamed includes/version.h to silcversion.h.
1284 * Added really preliminary support for OS/2 into the util
1285 library. Only thread & mutex API is implemented, others
1286 are still to be implemented. Created the lib/silcutil/os2/
1287 directory. Created also file includes/silcos2.h.
1289 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1292 Created lib/silcutil/beos/, and implemented all the needed
1293 functions to support SILC on BeOS. Created also file
1294 includes/silcbeos.h.
1296 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1298 * Added proper initializations to silc's irssi code, so it's
1299 now possible to load it as module. Affected files
1300 irssi/src/silc/core/silc-core.c,
1301 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1320 * Added `user_count' to the SilcChannelEntry which now tells the
1321 number of users on the channel. The user count is now saved
1322 in normal server of global channels as well. Affected files
1323 silcd/server.c, idlist.h, packet_receive.c and command.c.
1325 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1326 include file utility functions.
1328 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1329 instead of calling directly OS routines.
1331 * Fixed NICK change printing in Irssi SILC Client. Fixed
1332 KICKED notify printing in Irssi SILC Client. Affected file
1333 irssi/src/silc/core/client_ops.c.
1335 * Fixed a NICK change bug in client library, to not recreate the
1336 client_entry->channels hash table everytime nick is changed.
1337 Affected file lib/silcclient/client.c.
1339 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1341 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1342 the SKE interface a bit.
1344 * Fixed padding problem in PKCS#1. The padding was not actually
1345 random since the random number generator was used incorrectly.
1346 This security bug affects only when encrypting with PKCS#1, and
1347 it is not currently used at all in SILC. SILC only use signing
1348 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1350 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1352 * Rewrote the notify handling in Irssi SILC client to not call
1353 the events as signals. Fixes problems with Perl support.
1354 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1356 * Send the auto-nicking NICK command in client library with
1357 little timeout after connecting. The affected file is
1358 lib/silcclient/client.c.
1360 * Added following new config file settings:
1361 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1362 key_exchange_timeout, conn_auth_timeout, connections_max,
1365 Implemented all the new config settings handling in the server.
1367 Optimized the use of SKE Mutual flag usage. Use it only
1368 if connection authentication protocol is not based in public
1371 Renamed all SilcServerConfigSection* to SilcServerConfig*
1372 to have a bit shorter names.
1374 Affected files silcd/serverconfig.[ch], server.[ch], and
1377 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1403 Affected files are silcd/serverconfig.[ch].
1405 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1407 * Fixed command line parameter handling. All SILC initialization
1408 is now done in silc_core_init() which also fixes autoconnecting
1411 Affected files irssi/src/silc/core/silc-core.c,
1412 irssi/src/fe-text/silc.c.
1414 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1416 * Added new configuration options and blocks:
1417 keepalive_secs, reconnect_count, reconnect_interval,
1418 reconnect_interval_max, reconnect_keep_trying and
1419 require_reverser_lookup. Added ConnectionParam block, and
1420 implemented the connection parameters when connecting as
1421 initiator and when accepting connections as responder.
1423 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1424 whether given configuration value has been given already.
1426 Affected files silcd/serverconfig.[c], server.[c].
1428 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1429 algorithm parts and created new file silcalgs.conf, that
1430 is now included from the example_silcd.conf.in.
1432 * Optimized the silc_server_connect_to_router_second to take
1433 the connection configuration object from the SilcServerConnection
1434 object instead of finding it during the connecting phase.
1435 Added the configuration object to SilcServerConnection struct.
1436 Affected files silcd/server_internal.h, server.c.
1438 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Add the client on channel after it was resolved at the
1441 channel message receiving, and it was not already on the
1442 channel. Affected file lib/silcclient/client_channel.c.
1444 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1446 * Fixed the public key authentication to allocate always the
1447 destination signature buffer instead of using static buffer.
1448 Affected file silcd/protocol.c.
1450 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1452 * Unified the serverconfig.[ch]'s helper function interface.
1453 Affected file silcd/serverconfig.[ch].

1459 config file, allowing both public key and passphrase based
1460 authentication to be set at the same time.
1462 Added `prefer_passphrase_auth' setting in config file which
1463 can be used to set to prefer passwd auth if both passwd and
1464 public key is set. If not set, public key is preferred.
1465 This has effect only when being initiator (responder will try
1468 Added support for authentication with passphrase and public key
1469 at the same time. The passphrase is tried first always since
1470 it is faster to check.
1472 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1474 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1487 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * The silc_cipher_register, silc_hash_register and
1490 silc_hmac_register now checks if the object to be registered
1491 is registered already. Affected files are
1492 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.

1501 Payload. Affected file lib/silccore/silcchannel.c.
1503 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1504 as header filenames.
1506 * Removed lib/silcclient/README and created HTML file
1507 lib/silcclient/silcclient_using.html, which is now included
1508 as part of Toolkit documentation.
1510 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1512 * Fixed CUMODE_CHANGE notify handling to change the mode of
1513 correct client. Affected file lib/silcclient/client_notify.c.
1515 * Make silc_rng_alloc fail if it cannot allocate the sha1
1516 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1518 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1520 * Fixed the file transfer's key agreement payload to include
1521 zero port also if the hostname is NULL because it could not
1524 Call file transfer monitor callback now also if error occurs
1525 during key agreement protocol.
1527 Changed the silc_client_file_send interface to return the
1528 SilcClientFileError instead of session id. The session ID
1529 is returned into pointer provided as argument.
1531 Check that the file exists locally before sending the
1532 file transfer request at all.
1534 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1536 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1537 error than can occur while key agreement protocol. Affected
1538 file lib/silcclient/silcapi.h.
1540 * Fixed the event_mode CMODE handler to not crash when mode
1541 is changed and +k mode is set in the channel. Affected file
1542 irssi/src/silc/core/silc-channels.c.
1544 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1545 SILC_LOG_WARNING to give out Warning and not Error. Affected
1546 file lib/silcutil/silclog.c.
1548 * Fixed the channel message payload decryption in the function
1549 silc_channel_message_payload_decrypt to not modify the original
1550 buffer before it is verified that the message decrypted
1551 correctly. Otherwise, next time it is called with correct
1552 channel key it won't encrypt since the payload is corrupted.
1553 Affected file lib/silccore/silcchannel.c.
1555 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1557 * Do not constantly resize the window. A fix patch by cras.
1558 Affected file irssi/src/fe-text/screen.c.
1560 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1562 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1563 Affected file lib/silcutil/silcnet.c.
1565 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed a bug in hash table internal routine for traversing
1568 the table with foreach callback. The current entry may
1569 become invalid in the callback but it was referenced after
1570 the callback returned.
1572 Do not allow auto rehashing of hash table during the
1573 silc_hash_table_foreach operation, for same reasons as it is
1574 not allowed for SilcHashTableList. Affected files are
1575 lib/silcutil/silchashtable.[ch].
1577 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1579 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1580 Win32 DLL. extern's in header files are now declared with
1583 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1585 * Fixed private message handling. It used some old code that
1586 caused the client to crash. Affecte file is
1587 lib/silcclient/client_prvmsg.c.
1589 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1591 * Added function silc_client_add_channel,
1592 silc_client_replace_channel_id, and removed functions
1593 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1594 from client library.
1596 * Added cross reference of the joined channels to the
1597 SilcClientEntry, and changed the SilcChannelEntry's
1598 users list to SilcHashTable. The affected files are
1599 lib/silcclient/idlist.[ch].
1601 * Fixed a bug in hash table tarversing. While the hash table
1602 is traversed with SilcHashTableList the table must not be
1603 rehashed. It is now guaranteed that auto rehashable tables
1604 are not rehashed while tarversing the list. Also defined that
1605 silc_hash_table_rehash must not be called while tarversing
1606 the table. Added function silc_hash_table_list_reset that must
1607 be called after the tarversing is over. The affected files are
1608 lib/silcutil/silchashtable.[ch].
1610 * Changed all hash table traversing to call the new
1611 silc_hash_table_list_reset in server and in client library.
1613 * Added function silc_client_on_channel to return the
1614 SilcChannelUser entry if the specified client entry is joined
1615 on the specified channel. This is exported to application as
1616 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1618 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1620 * Fixed founder regaining problem with JOIN command on normal
1621 server. The notify for mode change must be sent always and
1622 not only if !cmd->pending. Affected file silcd/command.c.
1624 * Fixed the WHOWAS command's reply sending to support the
1625 lists correctly. Affected file silcd/command.c.
1627 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * When sending JOIN command to router for processing the
1630 sender's old command identifier was not saved back to the
1631 sender's command context, fixed now. The affected file is
1634 * Create the key in JOIN command of the router did not return
1635 the channel key, added check for this. Affected file is
1638 * Fixed a channel ID update bug in JOIN command reply. Do
1639 not directly upgrade the ID but call the function
1640 silc_idlist_replace_channel_id if the ID was changed.
1641 Affected file silcd/command_reply.c.
1643 * Fixed memory leaks from command calling if it would fail.
1644 Affected file silcd/command.c.
1646 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1648 * Applied patches from cras:
1650 Memory leak fixes around libaries, irssi window resize fix,
1651 new silclist.h and silcdlist.h, all extern inline changed to
1654 * Removed dotconf from lib/dotconf, not needed anymore.
1656 * Removed TRQ from lib/trq, not needed anymore.
1658 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1659 with server connections. Later this will be configurable
1660 in config file after new config file is done. Affected file
1663 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1665 * Fixed a crash in server related to channel announcements.
1666 Affected file silcd/server.c.
1668 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed memory leaks in silc_server_create_new_channel*
1671 functions. Affected file silcd/server.c.
1673 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1674 which ID was changed. This way the router will send the
1675 user list for the channel again, and server won't be in
1676 desync in some rare circumstances. Affected file is
1677 silcd/packet_receive.c.
1679 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1681 * Check for NULL socket pointer in the function
1682 silc_server_packet_send_to_channel_real. Affected file
1683 silcd/packet_send.c.

1686 list. Affected file silcd/packet_receive.c.
1688 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1690 * Fixed some header addition to Toolkit distribution in
1691 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1693 * Added lib/silcclient/client_ops_example.h as an template
1694 file for application programmers to quickly start using
1695 the SilcClientOperation functions in their application.
1696 Updated the lib/silcclient/README as well to tell about this
1697 nice file made available.
1699 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1701 * Call silc_server_remove_from_channels when removing client
1702 entry when NO_SUCH_CLIENT_ID was received. Affected file
1703 is silcd/command_reply.c.
1705 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1707 * Added server & router operator statistics updating. Affected
1708 file silcd/packet_receive.c and silcd/command.c.
1710 * Fixed the SERVER_SIGNOFF notify handling on normal server
1711 not to save the history information for clients. Same was
1712 fixed earlier in remove_clients_by_server function, but not
1713 here. Affected file silcd/packet_receive.c.
1715 * Raised the default connection-retry count from 4 to 7 in
1716 server. Affected file silcd/server.h.
1718 * Cancel any possible reconnect timeouts when we start the
1719 key exchange. Affected file silcd/server.c.
1721 * Do not reconnect on connection failure when SCONNECT was
1722 given. Affected files silcd/server.[ch].
1724 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1726 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1728 * Fixed the NICK command to always give the unformatted
1729 nickname to the one giving the NICK command. If unformatted
1730 nickname is cached already it will be formatted and the
1731 local entry will always get the unformatted nickname.
1732 Affected file lib/silcclient/idlist.c.
1734 * Fixed some double frees from client library commands.
1735 Affected file is lib/silcclient/command.c.
1737 * Fixed CUMODE command in server to assure that no one can
1738 change founder's mode than the founder itself, there was a
1739 little bug. Affected file silcd/command.c.
1741 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1743 * Removed the SilcClientCommandDestructor from the client
1744 libary, it is not needed anymore. Affected files are
1745 lib/silcclient/silcapi.h, command[_reply].[ch],
1746 client_notify, idlist.c.
1748 * Fixed GETKEY command to first resolve client, and then
1749 resolve the server only if the client was not found, instead
1750 of resolving both at the same time. Affected file is
1751 lib/silcclient/command.c.
1753 * Added silc_client_start_key_exchange_cb and lookup the
1754 remote hostname and IP address before starting the key
1755 exchange with server. The affected file is
1756 lib/silcclient/client.c.
1758 * The server's public key is now saved using the IP address
1759 of the server and not the servername for the filename.
1760 The hostname public key filename is checked as an fall back
1761 method if the IP address based filename is not found.
1763 Fixed the GETKEY command to save the fetched server key
1764 in correct filename.
1766 Print the remote server's hostname now when new key is
1767 received during connection process. Affected file is
1768 irssi/src/silc/core/client_ops.c.
1770 * Return always our own public key to the client if it asks
1771 for it with GETKEY command. Affected file silcd/command.c.
1773 * Removed the use_auto_addr variable from default config
1774 file since it was in wrong section. Affected file is
1777 * Fixed TOPIC_CHANGE notification to not route it when it
1778 was sent using silc_server_send_notify_to_channel function.
1779 Affected file silcd/command.c.
1781 * Fixed silc_server_send_notify_kicked to send the kicker's
1782 Client ID also, it was missing. Affected files are
1783 silcd/command.c, silcd/packet_send.[ch].
1785 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1787 * Do not save client history information in SERVER_SIGNOFF.
1788 Fixes the bug in normal server that it does not detect
1789 the client becoming valid after the server becomes back
1790 online. Affected file silcd/server_util.c.
1792 * Added `sock_error' field into the SilcSocketConnection
1793 context. When error occurs during socket operation (read
1794 or write) the error is saved. Added also new function
1795 silc_socket_get_error to return human readable socket error
1796 message. Affected files are lib/silcutil/silcsockconn.[ch],
1797 lib/silcutil/unix/silcunixsockconn.c, and
1798 lib/silcutil/win32/silcwin32sockconn.c.
1800 * The server now prints the socket error message in the
1801 signoff for client. Affected file silcd/server.c.
1803 * Fixed the `created' channel information sending from router
1804 to server in JOIN command. Checks now whether the channel
1805 really was created or not and set it according that.
1807 Fixed the JOIN command to use the client entry's current
1808 ID during the joining procedure instead of the one it sent
1809 in the command (it is checked though), since it can change
1810 between the packet processing and command processing, and
1811 would just case unnecessary pain in the client end. Affected
1812 file silcd/command.c.
1814 * Fixed a channel key payload sending to use correct channel
1815 ID when the server was forced to change the channel's ID by
1816 router. Router sent the key payload with the old Channel ID.
1817 Affected file silcd/packet_receive.c.
1819 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Call silc_server_save_channel_key only if the key payload
1822 was provided in the JOIN command's command reply. Affected
1823 file silcd/command_reply.c.
1825 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1827 * Fixed silc_mp_sizeinbase to return the value correctly with
1828 MPI. Affected file lib/silcmath/mp_mpi.c.
1830 * Fixed the stop_server signal to correctly stop the scheduler
1831 and gracefully stop the server when SIGTERM or SIGINT signals
1832 are received. Affected file silcd/silcd.c.
1834 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1836 * Simple handling of TERM and HUP signals. Also added some log
1837 flushing call around. Affected file is
1840 * Fixed small bugs in silclog.c. Now buffering output will take
1841 effect after 10 seconds since startup: This will ensure that
1842 no important startup messages are lost. Also output redirection
1843 will preserve original format ([Date] [Type] message).
1844 Affected file is lib/silcutil/silclog.c.
1846 * Added two options to the config file, in the logging section:
1847 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1848 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1850 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1852 * Do not print the warning about log files not being initialized
1853 more than once to avoid excess logging. Affected file is
1854 lib/silcutil/silclog.c.
1856 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1857 the SIM copying in make install in Makefile.am.pre.
1859 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1861 * Rewritten silclog APIs. Globally interesting changes follows:
1862 silc_log_set_files() changed to silc_log_set_file().
1863 silc_log_set_callbacks() changed to silc_log_set_callback().
1864 ROBOdoc documented silclog header file.
1865 SilcLogCb now returns bool to wether inihibit the default
1866 handler or not (to keep the old behaviour return always TRUE).
1867 The new APIs should also fix the problem of the
1868 silcd_error.log file that was written in the current directory.
1871 Log files streams will remain opened after silc_log_set_file()
1872 call, means less CPU usage notably on high traffic servers.
1873 File streams are now full buffered, and flushed to the disk
1874 every 5 minutes, lesses HD activity and CPU usage.
1875 Messages can be redirected, allowing admins to configure
1876 one single logfile for all server messages.
1877 the silc_log_quick global variable to activate fast-logging.
1878 Affected files lib/silcutil/silclog.[ch]
1880 * Changed some code to conform new silclog APIs. Affected
1881 files are doc/example_silcd.conf.in, silcd/server.c
1882 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1885 * Fixed a memory leak that could occur in some situations.
1886 Affected file silcd/serverconfig.c.
1888 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1890 * Added the silc_client_del_client to remove the client from
1891 all channels as well. Affected file lib/silcclient/idlist.c.
1893 * Fixed the client library to correctly remove the client
1894 from all channels when the client entry is being destroyed.
1895 Affected file lib/silcclient/client_notify.c, command.c.
1897 * Added auto-nicking support to the client library. If the
1898 applicatio now sets client->nickname it will be sent to the
1899 server after connecting by the library. This way for example
1900 SILCNICK (or IRCNICK) environment variables will have effect
1901 and always change the nickname automatically to whatever
1902 it is wanted. Affected file lib/silcclient/client.[ch].
1904 * Renamed silc_server_command_bad_chars to the
1905 silc_server_name_bad_chars and moved it to the
1906 silcd/server_util.[ch]. Added also new function
1907 silc_server_name_modify_bad to return nickname that
1908 includes bad characters as new nickname without those
1909 bad characters. This check and modify is now used in
1910 silc_server_new_client when the username is initially set
1911 as nickname, so it must be checked to be valid nickname.
1912 Affected file silcd/packet_receive.c.
1914 * The nickname length is now taken from the packet for real
1915 and not trusted to strlen() since it clearly can return
1916 wrong length for nickname including bad characters. This
1917 also applies to channel names. Affected file silcd/command.c.
1919 * Removed the lib/silcsilm/modules directory. Modules are now
1920 compiled into the lib/silcsim. Fixed the copying of the
1921 modules to follow symbolic links in Makefile.am.pre.
1923 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1925 * Fixed silc_string_regexify list creation. Fixes bugs with
1926 BAN and INVITE commands in server. The affected file is
1927 lib/silcutil/unix/silcunixutil.c.
1929 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Removed the command destructor entirely from the server's
1932 command and command reply routines. It is not needed, and
1933 its usage was buggy and caused crashes. Affected files are
1934 silcd/command[_reply].[ch].
1936 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Cancel protocol and NULL sock->protocol if timeout
1939 occurred during protocol. Affected file silcd/server.c.
1941 * Cancel protocol timeouts always before calling the final
1942 callback, to assure that after final callback is called
1943 no other state will be called for the protocol anymore.
1944 Affected file silcd/protocol.c.
1946 * Print error log if incoming connection configuration could
1947 not be found. Affected file silcd/server.c.
1949 * Fixed JOIN command to correctly save the founder mode
1950 to the client on normal SILC server, when the channel
1951 was created by the router. Affected file silcd/command.c.
1953 * Fixed LIST command (hopefully) to send correct reply
1954 packets. Affected file silcd/command.c.
1956 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * The silc_packet_receive_process now returns FALSE if the
1959 read data was invalid packet, and TRUE if it was ok.
1961 The server now checks that if unauthenticated connection
1962 sends data and its processing fails the server will close
1963 the connection since it could be a malicious flooder.
1965 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1967 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Make sure the warning about error opening a log file is
1970 printed only once and not everytime it fails (produces
1971 too much useless log). Affected file lib/silcutil/silclog.c.
1973 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1975 * Made the silc_server_daemonise() function more readable.
1976 Affected file silcd/server.c.
1978 * Pid file is now optional, the user may comment it out from
1979 the config file. Removed define SILC_SERVER_PID_FILE, we
1980 don't need a default any longer. Affected file
1981 configure.in.pre, lib/Makefile.am.pre.
1983 * Make some use of the pid file. The server now dies at startup
1984 if it detects a valid pid file on his path. The server would
1985 die anyway in this circumstance, because of the bind() failure.
1986 Affected file silcd/silcd.c.
1988 * No longer compiling lib/dotconf.
1990 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Fixed JOIN command parsing not to crash. Affected file
1993 lib/silcclient/command.c.
1995 * Fied the NICK_CHANGE notify to add the new client entry
1996 even it is resolved. This removes an <[unknown]> nick
1997 thingy bug in the client. Affected file is
1998 lib/silcclient/client_notify.c.
2000 * Do not try to allocate 0 bytes (efence does not like it)
2001 in lib/silccore/silccomand.c when encoding payload.
2003 * Do not take IRCNICK as nickname in Irssi SILC client since
2004 it is not possible to set nickname before hand connecting
2005 the server (TODO has an entry about adding auto-nicking
2008 * Changed the silc_server_command_pending to check whether
2009 there already exists an pending entry with the specified
2010 command, command identifier and pending callback. This is
2011 to fix IDENTIFY and WHOIS related crashes that may register
2012 multiple pending commands with same identifier. Affected
2013 file silcd/command.c.
2015 * Fixed the server to reconnect to the router even if it
2016 was already reconnecting and EOF was received. This to
2017 fix a possibility that the server wouldn't ever try to
2018 auto-reconnect to the router. Affected file silcd/server.c.
2020 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Fixed the server's password authentication to use the
2023 length of the locally saved password, and not the one
2024 sent in the packet. Affected file silcd/protocol.c.
2026 * Fixed same password authentication problem in the
2027 Authentication Payload handling routines in
2028 lib/silccore/silcauth.c.
2030 * Yet another password authentication problem fixed with
2031 channel password handling in silcd/command.c.
2033 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * If first character of string in silc_parse_userfqdn is '@'
2036 then do not parse it. Affected file is
2037 lib/silcutil/silcutil.c.
2039 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Fixed minor bug in IDENTIFY command reply sending, which
2042 caused various weird problems during JOIN when it was
2043 resolving names for users. Affected file silcd/command.c.
2045 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Fixed the IDENTIFY command reply sending to chech better valid
2048 clients. It was possible to send incomplete list of replies.
2049 Affected file silcd/command.c.
2051 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Added silc_client_command[s]_[un]register functions now to
2054 dynamically register the commands in client library. Removed
2055 the static table of commands. This allows the client library
2056 to call commands without causing the application to know about
2057 what commands library has called.
2059 Removed the INFO command reply kludge to detect when the command
2060 was called by library. Now library use its own command reply
2061 function for INFO command.
2063 Added function silc_client_command_call to call a command.
2064 Application can use it to call command, not access the structure
2067 Now all commands that are sent by the client library (not
2068 explicitly sent by application) use own command reply functions.
2070 Affected files around lib/silcclient/ and in
2071 irssi/src/silc/core/.
2073 * Fixed the WHOIS command reply sending to chech better valid
2074 clients. It was possible to send incomplete list of replies.
2076 Fixed the WHOIS and IDENTIFY to send the request to router
2077 if normal server did not do it and did not find any results.
2079 Affected file silcd/command.c.
2081 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Moved the internal data from SilcClient context into its
2084 own file, not accesible to application. Affected files
2085 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2086 and other files in client library.
2088 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Added doc/examples installation target in Makefile.am.pre.
2093 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2096 commands the found client entry will be removed from the
2097 cache, after notifying application about the error. Affected
2098 file lib/silcclient/command_reply.c.
2100 * Changed the /MSG to check for exact nickname user gave, and
2101 not let `nick' match `nick@host' if it is only one found. Now,
2102 user must type the exact nickname (like nick@host2) even if
2103 there are no more than one same nicks found. This is to avoid
2104 a possibility of sending nickname to wrong nickname since
2105 `nick' could match `nick@host'. Affected file is
2106 irssi/src/core/silc-servers.c.
2108 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Do not print "you are now server operator" or similar when
2111 giving /away command. Affected files are
2112 irssi/src/silc/core/client_ops.c, silc-servers.h.
2114 * Made the silc_server_command_pending_error_check to send
2115 the same command reply payload it received back to the
2116 original sender of the command. This way all arguments
2117 that was received by the server will be received by the
2118 client too. Affected file silcd/command.c.
2120 * Added the silc_idcache_add to return the created cache entry
2121 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2123 * Add global clients to expire if they are not on any channel.
2124 This is because normal server will never know if they signoff
2125 if they are not on any channel. The cache expiry will take
2126 case of these entries. This is done by normal servers only.
2127 The affected files are silcd/command_reply.c,
2128 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2130 * If server receives invalid ID notification for WHOIS or
2131 IDENTIFY and the ID exists in the lists, it is removed.
2132 Affected file silcd/command_reply.c.
2134 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2135 in client then client entry that it matches is searched and
2136 the nickname is printed on the screen for user. Affected
2137 file irssi/src/silc/core/client_ops.c.
2139 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Use cache entry expire time in the LIST command reply to
2142 purge old entries from the cache after the LIST command
2143 reply has been received. This way we don't have non-existent
2144 entries in the cache for too long. Affected file is
2145 silcd/command_reply.c.
2147 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * If we are normal server, and we've not resolved client info
2150 in WHOIS or IDENTIFY from router, and it is global client,
2151 we'll check whether it is on some channel. If it is not
2152 then we cannot be sure about its validity and will resolve it
2153 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2154 file silcd/command.c.
2156 * Search channel by name (if possible) rather than by ID
2157 in IDENTIFY command's command reply. Affected file is
2158 silcd/command_reply.c.
2160 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2163 Updated specs and implemented it. Affected file silcd/command.c,
2164 silcd/packet_send.c and silcd/packet_receive.c.
2166 * Implemented the <founder auth> payload handling in the JOIN
2167 command. If provided all conditions for channel joining
2168 except requirement to provide correct passphrase can be
2169 overrided by the channel founder. Updated the protocol specs.
2170 Affected file silcd/command.c.
2172 Added support for founder auth in JOIN command in client
2173 library. Fixed the parsing of the JOIN command now to support
2174 all options as they should be. The affected file is
2175 lib/silcclient/command.c.
2177 * Optimized the WHOIS and IDENTIFY commands to send the request
2178 to router only if it includes nicknames or other names. If
2179 they include only IDs then check the local cache first before
2180 routing. Affected file is silcd/command.c.
2182 * Added channels topic announcements. Affected file is
2183 silcd/packet_receive.c and silcd/server.c.
2185 * Fixed the silc_server_send_notify_topic_set to really destine
2186 the packet to channel. Affected file silcd/packet_send.c.
2188 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2189 library. Affected file lib/silcclient/client_notify.c.
2191 * Added UMODE announcements. Affected file silcd/server.c.
2193 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Memory leak fixes in:
2197 lib/silcutil/silcsockconn.c
2198 lib/silcske/silcske.c
2199 lib/silcske/groups.c
2201 lib/silccrypt/silcpkcs.c
2202 lib/silccore/silccommand.c
2203 lib/silccore/silcidcache.c
2208 * ROBOdoc documented the lib/silcske/groups.h file and a
2209 bit changed the interface for better.
2211 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2213 * Update the client entry context in the ID cache after
2214 nick change. Affected file lib/silcclient/command.c.
2215 Fixes the CUMODE command when regaining founder privileges,
2216 and a little WHOIS problem.
2218 * Fixed silc_net_gethostbyname to correctly call the
2219 inet_ntop. Affected file lib/silcutil/silcnet.c.
2221 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2223 * Added IPv6 support checking to the configure.in.pre, added
2224 also --enable-ipv6 option to override the check. Affected
2225 file configure.in.pre.
2227 * The silc_thread_create now calls the start function
2228 directly if threads support is not compiled in. Removes
2229 ugly #ifdef's from generic code. Affected files are
2230 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2232 * Added silc_net_gethostby[name/addr]_async to asynchronously
2233 resolve. Affected files are lib/silcutil/silcnet.[ch].
2235 * Added support for rendering IPv6 based server, client and
2236 channel IDs. Affected file lib/silcutil/silcutil.c.
2238 * Added support for creating IPv6 based server IDs. Affected
2239 file is silcd/serverid.c.
2241 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2243 * Added silc_net_gethostby[addr/name] into the
2244 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2245 routines. Added silc_net_is_ip[4/6]. Affected file is
2246 lib/silcutil/unix/silcunixnet.c. All routines that take
2247 address as argument now supports both IPv4 and IPv6 addresses.
2249 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2251 * Fixed LIST command reply sending in server. Affected file
2254 * Server now sends the kicker's client ID in the KICK notify
2255 to the kicked client. Affected file silcd/command.c.
2257 * The client library now parses the kickers client ID and
2258 UI displays it. Affected files lib/silcclient/client_notify.c
2259 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2261 * Made all payload parsing function prototypes consistent.
2262 They all take now const unsigned char * and uint32 pair as
2263 the payload data instead of SilcBuffer. Changes all around
2264 the source tree. Other unsigned char* -> const unsigned char*
2265 changes around the tree as well.
2267 * Optimized SFTP client and server packet sending not to
2268 allocate new buffer for each packet but to recycle the
2269 first allocated buffer. Affected files are
2270 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2272 * Optimized the SFTP client to use SilcList instead of
2273 SilcDList for requests, because it is faster. Affected file
2274 is lib/silcsftp/sftp_client.c.
2276 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2277 into lib/silccore/silcid.[ch].
2279 Renamed silcpayload.[ch] into silcargument.[ch].
2281 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * If client entry is deleted with active key agreement
2284 session, abort the session.
2286 The silc_client_abort_key_agreement now calls the completion
2287 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2289 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2292 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Don't use __restrict in older GCC's. Affected file is
2295 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2297 * silc_net_localhost now attempts to reverse lookup the
2298 IP/hostname. Affected file lib/silcutil/silcnet.c.
2300 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2301 command. It can be used to gain founder privileges at
2302 the same time when joining the channel.
2304 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2305 kicker's client ID as well. Updated protocol specs.
2307 Defined that the server must send SILC_COMMAND_IDENTIFY
2308 command reply with error status to client who sent
2309 private message with invalid client ID.
2311 Updated the protocol specification.
2313 * Added silc_server_send_command_reply to send any
2314 command reply. Affected file silcd/packet_send.[ch].
2316 * Added silc_id_payload_encode_data to encode ID payload
2317 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2319 * The server now send IDENTIFY command reply with error
2320 status if client ID in private message is invalid. Affected
2321 file silcd/packet_receive.c.
2323 * Save the server key file with server's IP address in
2324 the filename instead of hostname. The affected file is
2325 irssi/src/silc/core/client_ops.c.
2327 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2332 * Added libtool support for compiling shared objects in
2333 lib/silcsim. Affected file configure.in.pre and
2334 lib/silcsim/Makefile.am. Original patch by cras.
2336 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Pid file configuration, and server's config file fixes
2339 patch by toma. Updated CREDITS file.
2341 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Fixed silc_client_channel_message to not try to decrypt
2344 the message twice if it resolved the destination client
2345 information. This could cause of dropping one channel
2346 message. Affected file lib/silcclient/client_channel.c.
2348 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2351 lib/silcclient/client.c. This function is used when the SILC
2352 Client is run under some other scheduler, or event loop or
2353 main loop. On GUI applications, for example this may be
2354 desired to used to run the client under the GUI application's
2355 main loop. Typically the GUI application would register an
2356 idle task that calls this function multiple times in a second
2357 to quickly process the SILC specific data.
2359 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2361 * Fixed silc_server_drop() for dropping the supplementary
2362 groups as well, this could cause a security hole on some
2365 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2370 * Write PID file after dropping privileges. Added -F option
2371 to run server on foreground. A patch by debolaz.
2372 Affected files silcd/server.c, silcd/silcd.c.
2374 * Fixed MOTD to return the MOTD file server name. Affected
2375 file silcd/command.c.
2377 * Added INFO command reply handling to the Irssi SILC Client.
2378 Affected file irssi/src/silc/core/client_ops.c.
2380 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Fixed the silc_idcache_list_* routines to really support
2383 the dynamic list. Fixes a crash. Affected file is
2384 lib/silccore/silcidcache.c.
2386 * Fixed the LIST command reply to really call LIST command's
2387 pending callbacks. Affected file silcd/command_reply.c.
2389 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Update conn->local_entry->nickname after giving NICK
2392 command. Affected file lib/silcclient/command.c.
2394 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2396 * Added the [pid] option to the silcd configuration file
2398 Affected files: serverconfig.[ch] and silcd.c
2400 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Save fingerprint in WHOIS command reply in server.
2403 Affected file silcd/command_reply.c.
2405 * Fixed NICK commands pending callback registration.
2406 Affected file lib/silcclient/command.c.
2408 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * Use ++server->cmd_ident when sending commands in server,
2411 instead of random number. Affected file silcd/command.c.
2413 * Fixed GETKEY command reply to call actually GETKEY pending
2414 command callbacks. Affected file silcd/command_reply.c.
2416 * A bit stricter check for nicknames. Check for same nickname
2417 in NICK command also. Affected file silcd/command.c.
2419 * Do not call INFO command everytime client ID changes, only
2420 during first connecting. Affected file lib/silcclient/client.c.
2422 * Set the new nickname only after successful command reply for
2423 NICK command is returned by server. Affected file
2424 lib/silcclient/command.c.
2426 * Remove nicknames from nicklist during server_signoff notify.
2427 Should fix /NAMES bit more. The affected file is
2428 irssi/src/silc/core/silc-channels.c.
2430 * Added `fingerprint' field to the SilcIDListData in the
2431 silcd/idlist.h to hold the fingerprint of the client's
2434 Send the fingerprint of the client's public key in WHOIS
2437 Affected files silcd/command.c, and silcd/idlist.[ch].
2439 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2440 create fingerprint from given data.
2442 * Show the fingerprint of the client's public key in WHOIS.
2443 Affected files irssi/src/module-formats.[ch] and
2444 irssi/src/silc/core/client_ops.c.
2446 * Format the multiple same nicknames also during JOIN and
2447 NICK_CHANGE notifys. Affected file is
2448 lib/silcclient/client_notify.c.
2450 * Do not print error on screen for invalid private message
2451 payload since it can come if someone is sending private
2452 messages with wrong key. Affected file
2453 lib/silccore/silcprivate.c.
2455 * Fixed multiple concurrent /PING crash. Affected file
2456 lib/silcclient/command.c.
2458 * Changed the wrong ID encoding. All IP addresses must be
2459 in MSB first order in encoded format. They were encoded
2460 wrong and was in LSB format. Affected files are
2461 silcd/serverid.c, lib/silcutil/silcutil.c.
2463 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2465 * Call the `connect' client operation through the scheduler
2466 in case of error. Affected file lib/silcclient/client.c.
2468 * Call the `failure' client operation even if the error
2469 occurred locally during a protocol. Affected file is
2470 lib/silcclient/protocol.c.
2472 * Added support of sending LIST command to router from normal
2473 server. This way normal server can get list of all channels
2474 in the network too. Fixed the channel list sending in the
2475 server too. Affected files are silcd/command.c, and
2476 silcd/command_reply.[ch].
2478 * Added silc_server_update_channels_by_server and
2479 silc_server_remove_channels_by_server. They are used during
2480 disconnection of primary router and in backup router protocol.
2481 Affected file silcd/server_util.[ch], silcd/server.c and
2482 silcd/server_backup.c.
2484 * Fixed channel adding to global list in IDENTIFY command
2485 reply in server. Affected file silcd/command_reply.c.
2487 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * If the incoming packet type is REKEY or REKEY_DONE process
2490 that packet always synchronously. Fixes yet another MAC
2491 failed error on slow (dialup) connections. Affected file
2492 lib/silcclient/client.c and silcd/server.c.
2494 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Call check_version SKE callback for initiator too. Affected
2497 file lib/silcske/silcske.c.
2499 * Implemented fix for security hole found in the SKE that was
2500 fixed in the specification few days back; the initiator's
2501 public key is now added to the HASH value computation.
2502 Added backwards support for the old way of doing it too, for
2503 old clients and old servers. Affected file is
2504 lib/silcske/silcske.c.
2506 * Enabled mutual authentication by default in SKE. If initiator
2507 is not providing mutual authentication the responder will
2508 force it. This will provide the proof of posession of the
2509 private key for responder. The affected files are
2510 lib/silcclient/protocol.c and silcd/protocol.c.
2512 * Do not cache anymore the server's public key during SKE.
2513 We do mutual authentication so the proof of posession of
2514 private key is done, and if the server is authenticated in
2515 conn auth protocol with public key we must have the public
2516 key already. Affected file silcd/protocol.c.
2518 * Added new global debug variable: silc_debug_hexdump. If
2519 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2520 file lib/silcutil/silclog.[ch].
2522 * Fixed compilation warning due to char * -> const char *.
2523 Affected files lib/silcutil/silcnet.h, and
2524 lib/silccore/silcauth.[ch].
2526 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Fixed CMODE command when new channel key was created. If
2529 the creation failed the old key was removed. Next time giving
2530 same command would crash the server since the old key was
2531 freed already. Affected file silcd/command.c.
2533 * Fixed the silc_server_announce_get_channels to not crash
2534 on reconnect. Affected file silcd/server.c.
2536 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Added silc_log_set_debug_string function to set a regex
2539 string to match for debug output. Only the function names,
2540 or filenames matching the given debug string is actually
2541 printed. This way it is possible to filter out those debug
2542 strings that user is not interested in.
2544 Fixed a bug in silc_string_regexify.
2546 Affected files lib/silcutil/silclog.[ch], and
2547 lib/silcutil/unix/silcunixutil.c.
2549 * Changed the -d options in both server and Irssi SILC client
2550 to take the debug string as argument. Affected files
2551 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2553 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Added silc_hash_babbleprint to create a Bubble Babble
2556 Encoded fingerprint. The encoding is developed by Antti
2557 Huima (draft-huima-babble-01.txt), and it creates human
2558 readable strings out of binary data. Affected file
2559 lib/silccrypt/silchash.[ch].
2561 * Print the babble print now in addition of fingerprint as well
2562 in Irssi SILC client. Affected files are
2563 irssi/src/fe-common/silc/module-formats.[ch],
2564 irssi/src/fe-common/silc/core/client_ops.c.
2566 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Fixed a security problem found in SKE. The initiator's
2569 public key too is now added to the HASH hash value creation
2570 which is signed by the responder to create the SIGN value.
2571 This will prevent anyone in the middle to lie to the responder
2572 about the initiator's public key. If this is done now, the
2573 man in the middle will get caught. Updated the protocol
2576 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Better installation directory handling. Configure module
2579 paths and other paths automatically to example_silc* files
2580 in doc/. A patch by toma.
2582 * Fixed compiler warning from MPI library, and from SILC RNG.
2585 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2586 It can be configured with ./configure. A patch by toma.
2588 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Find correct make to use in prepare-clean. A patch by
2591 toma. Affected file prepare-clean.
2593 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2595 * Added irssi variables use_auto_addr, auto_bind_ip,
2596 auto_bind_port and auto_public_ip.
2598 * Changed the interface for silc_client_send_key_agreement
2599 in lib/silcclient/silcapi.h
2603 irssi/src/silc/core/silc-core.c
2605 lib/silcclient/silcapi.h
2606 irssi/src/silc/core/silc-channels.c
2607 lib/silcclient/client_keyagr.c
2610 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Added silc_pkcs_public_key_compare to compare two
2613 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2615 * Check that the client who set the founder mode on the
2616 channel is the same client that is giving the founder
2617 mode to itself. It is done by comparing the saved public
2618 key (it is saved even in the authentication is passphrase).

2627 client library. Affected file lib/silcclient/client.c.
2629 * Fixed the silc_client_packet_parse to not to increase
2630 the packet sequence number if the conn->sock and the
2631 current socket connection is not same. This can happen
2632 for example during key agreement when the conn includes
2633 multiple socket connections (listeners). Affected file
2634 lib/silcclient/client.c.
2636 * The sender of the file transfer request now provides also
2637 the pointer (listener) for the key exchange protocol. If
2638 the listener cannot be created then it sends empty key
2639 agreement and lets the receiver provide the listener.
2641 Added `local_ip' and `local_port' arguments to the
2642 silc_client_file_send. If they are provided they are used,
2643 if not then it will attempt to find local IP address, if
2644 not found or bind fails then the remote client will provide
2647 Affected files are lib/silcclient/client_ftp.c and
2648 lib/silcclient/silcapi.h.
2650 * Extended the FILE SEND command to support defining the

2657 of the client's public key (if the proof of posession of the
2658 corresponding private key is verified by the server).
2659 Updated to the protocol specification.
2661 * Added support of receiving the client's public key's
2662 fingerprint in command reply in client library. Affected
2663 file is lib/silcclient/command_reply.c, and
2664 lib/silcclient/idlist.[ch].

2723 preserve the WHOWAS info for the client. Affected file
2724 silcd/server_util.c.
2726 * Fixed SERVER_SIGNOFF notify handling in the server. The
2727 server is now able to process incoming SERVER_SIGNOFF notify
2728 for a server that it doesn't even know about. It will remove
2729 the clients provided in the notify. Affected file
2730 silcd/packet_receive.c.
2732 * Check for partial packet in data queue after every packet that
2733 was found from the queue. Return and wait for more data if
2734 there is partial data in queue. Affected file is

2752 irssi/src/fe-common/silc/module-formats.[ch].
2754 * Wrote a help file for FILE command.
2756 * Added silc_rng_global_get_byte_fast to get not-so-secure
2757 random data as fast as possible. Random data is read from
2758 /dev/urandom if available and from the SILC RNG if not
2759 available. It is used in padding generation. Affected file
2760 lib/silccrypt/silcrng.[ch].
2762 * All packets in client library are now processed synchronously.
2763 Optimized packet processing a lot. Affected file
2764 lib/silcclient/client.c.

2775 * Assure that silc_client_notify_by_server_resolve does not
2776 resolve the client information multiple times. If it cannot
2777 be found by the first it cannot be found at all. Affected
2778 file lib/silcclient/client_notify.c.
2780 * Fixed WHOWAS command reply calling. Affected file
2781 lib/silcclient/command_reply.c.
2783 * Removed all references to silc_idlist_get_client from the
2784 Irssi SILC client since that call is internal call used by
2785 the library. The Irssi SILC client will use now client
2786 retrieval functions found in silcapi.h.
2788 * Fixed a bug in resolving nickname info before sending
2789 private message. It used freed memory. Affected file
2790 irssi/src/silc/core/silc-servers.c.

2811 * Added silc_net_localip to return local host's IP address.
2812 Affected file lib/silcutil/silcnet.[ch].
2814 * If key exchange or rekey protocol is active for a connection
2815 parse all packets syncronously since there might be packets
2816 in packet queue that we are not able to process without first
2817 processing packets before them. Affected file silcd/server,
2818 lib/silcclient/client.c.
2820 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2821 whether library should continue processing the packet.
2822 Affected file lib/silccore/silcpacket.h.

2872 Make sure also that USERS command reply does not resolve
2873 twice information. Affected file is
2874 lib/silcclient/command_reply.c.
2876 Make sure that silc_client_get_clients_by_list does not
2877 resolve twice same information.
2879 * Check for valid client->id in the silc_server_free_client_data.
2880 Affected file silcd/server.c.
2882 * Fixed /GETKEY nick@server not to crash if the server entry

2895 * Call the silc_server_udpate_servers_by_server in the
2896 primary router that comes back online in the backup resuming
2897 protocol. Otherwise it routes packets wrong. Affected file
2898 silcd/server_util.[ch], silcd/server_backup.c.
2900 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2903 lib/silcutil/silcbuffmt.[ch].

2906 length. Affected file lib/silccore/silcpacket.[ch].
2908 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2909 length for maximum padding up to 128 bytes). Affected
2910 file lib/silccore/silcpacket.h.
2912 * Removed all backwards support for old 0.5.x MAC thingies.
2913 The SILC packet header change makes it impossible to be
2914 backwards compatible.
2916 * Send the ENDING packet with timeout in the backup resuming
2917 protocol. This is to assure that all routers has connected
2918 to the primary router. Affected file silcd/server_backup.c.
2920 * Changed the RNG to take the first IV from random data. It
2921 used to take it from zero actually. Changed the RNG also
2922 to use /dev/urandom during session. /dev/random is used
2923 in initialization. Affected file lib/silccrypt/silcrng.[ch].

2928 (the packet length) encrypted. Affected files aroung the
2929 code tree, lib/silccore/silcpacket.[ch]. Removed the
2930 SilcPacketCheckDecrypt callback. It is not needed anymore
2931 since the silc_packet_receive_process will determine now
2932 whether the packet is normal or special.

2943 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Allow backup router to announce servers. All servers
2946 announced by backup router are added to the global list
2947 automatically. Update hte server's socket to our primary
2948 router also when backup router announces a server.
2949 Affected file silcd/packet_receive.c.
2951 * Do not update the client->router in the function
2952 silc_server_udpate_clients_by_server if the client is on
2953 global list. We might fail to find any specific server
2954 for locally connected clients and local cell clients. They
2955 should still use the `from' and not `to' as client->router.
2956 This fixes backup router resuming protocol. Affected file
2957 silcd/server_util.c.
2959 * Decrease channel statistics count only if the channel
2960 deletion worked. Affected files are silcd/server.c and
2961 silcd/server_util.c.
2963 * Added silc_server_update_servers_by_server to update origin
2964 of all server entries. Used during backup router protocol.

2981 to the router it came from. Affected file is
2982 silcd/packet_send.c. Fixed memory leak too.
2984 * Announce informations for incoming router connection, but
2985 only after checking if it is replaced by backup router.
2986 Affected file silcd/packet_receive.c.
2988 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2991 router environment. Affected file silcd/server_backup.c.
2993 * Route packet only to one router in the function
2994 silc_server_packet_send_to_channel. Affected file is
2995 silcd/packet_send.c.
2997 * Fixed silc_server_send_notify_dest to set the broadcast
2998 flag. Fixed the silc_server_send_notify_topic to actually
2999 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3000 Affected file silcd/packet_send.c.
3002 * Changed the SFTP Filesystem interface. Changed the
3003 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3004 the filesystem operation function. The SilcSFTPFilesystem
3005 is now a context that is allocated by all filesystem allocation
3006 functions and it already includes the operations structure
3007 and filesystem specific context. It is given as argument
3008 now to the silc_sftp_server_start. This made the interface
3009 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3010 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3012 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Changed the backup router adding and getting interfaces
3015 in the server. The router that will be replaced by the

3077 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3078 in the server to indicate disabled entry. All data read
3079 from the connection will be ignored and no data is sent
3080 for entry that is disabled. Affected files are
3081 silcd/idlist.h, silcd/server.c.

3132 new packet type SILC_PACKET_FTP and defined File Transfer
3133 Payload. The mandatory file transfer protocol is SFTP
3134 (SSH File Transfer Protocol). Affected file in addition
3135 of the internet draft is lib/silccore/silcpacket.h.
3137 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3138 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3139 is used as part of backup router protocol when the primary
3140 router of the cell is back online and wishes to resume
3141 the position as primary router.
3143 * Redefined the MAC generation keys in the protocol. The
3144 same key is not used anymore in both direction. Both
3145 direction will now use different keys for sending and
3146 receiving. This fixes a potential security flaw. This
3147 change causes incompatibilities in the protocol.
3149 * Redefined also the MAC computation from the packet.
3150 An packet sequence number is now added to the MAC
3151 computation. This prevents possible replay attacks against
3152 the protocol. This change too causes incompatibilities
3155 Added `sequence' field to the SilcPacketContext to hold
3156 the current sequence number for the packet.
3158 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * Added `created' field to the SilcIDListData in the file
3161 silcd/idlist.h to indicate the time when the entry was
3164 * Added `created' field to the SilcChannelEntry too. Affected
3165 file silcd/idlist.h.
3167 * Added `creation_time' aguments to all the announcement functions
3168 in the server. If it is provided then only the entries that
3169 was created after the provided time frame are actually
3170 announced. Affected file silcd/server.[ch].
3172 * The protocol says that the Channel ID's IP address must be
3173 based on the router's IP address. Added check for this in
3174 the silc_server_new_channel when processing incoming New Channel
3175 Payload. Affected file silcd/packet_receive.c.
3177 * Print out the correct version with --version in SILC client.
3178 Affected file irssi/src/silc/core/silc-core.c.
3180 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Fixed WHOWAS command to check for completnes of the client
3183 entry always, not just when the command is coming from client.
3184 Affected file silcd/command.c.
3186 * Added new function silc_server_packet_queue_purge to purge the
3187 outgoing data queue to the network. After the function returns
3188 it is guaranteed that the outgoing packet queue is empty.
3189 Affected file silcd/packet_send.[ch].
3191 * Purge the outgoing packet queue in the rekey protocol's final
3192 callback to assure that all rekey packets go to the network
3193 before quitting the protocol. Affected file silcd/server.c.
3195 * Added silc_client_packet_queue_parse as similar function as
3196 in server to the client library. The affected file is
3197 lib/silcclient/client.c.
3199 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Splitted silcd/server.c and created silcd/server_util.[ch]
3202 for utility functions.
3204 * Added new socket flag SILC_SF_DISABLED to indicate that the
3205 connection is open but nothing can be sent to or received from
3206 the connection. Affected file lib/silcutil/silsockconn.[ch].
3207 The checking for disabled socket is checked in the low level
3208 silc_socket_write and silc_socket_read functions.
3210 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Allow only nicknames and channel names that fits into the
3213 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3215 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * When processing JOIN command reply in server check that if
3218 the channel exists in our global list we'll move it the local
3219 list. Affected file silcd/command_reply.c.
3221 * Fixed the check whether client is joined on the channel already
3222 in JOIN command. Affected file lib/silcclient/command.c.
3224 * Fixed the JOIN command reply to check whether the channel
3225 already exists. Affected file lib/silcclient/command_reply.c.
3227 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Added silc_ske_status_string to map the SKE error numbers
3230 to readable strings. The affected files are
3231 lib/silcske/silcske[_status].[ch].
3233 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Do not show the private channels on the WHOIS channel list
3236 as it is not allowed by the protocol. The affected file is
3239 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Assure that the packet length digged from the actual packet
3242 is something sensible in the silc_packet_decrypt_rest_special
3243 in lib/silccrypt/silcpacket.c.
3245 * Free and NULL the allocated pointer in silc_hmac_alloc if
3246 the HMAC allocation fails. The affected file is
3247 lib/silccrypt/silchmac.c.
3249 * Print the selected security properties to the log files in
3250 the server. Affected file silcd/protocol.c.
3252 * Add SKE's reference counter even if calling the completion
3253 callback manually. Otherwise it goes negative, although it
3254 does not cause any problems. The affected file is
3255 lib/silcske/silcske.c.
3257 * Remove the client entry with short timeout after giving the
3258 KILL command. Affected file lib/silcclient/command.c.
3260 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3261 case all found clients are already disconnected (WHOWAS would
3262 found them) in the server. Affected file silcd/command.c.
3264 * Update the last_receive (time of last data received) to be
3265 updated only when received private or channel message so that
3266 the idle time showed in WHOIS makes more sense.
3268 * Added boolean field `valid' in to the SilcClientEntry in the
3269 client library to indicate whether the entry is valid or not.
3270 This fixes the nickname change bug on channel when changing
3271 the nickname to be same than the old (like nick to Nick) the
3272 nickname formatter doesn't set the new nick anymore to Nick@host.
3273 Affected file lib/silcclient/idlist.[ch].
3275 * Now actually fixed the nickname changing on disconnection.
3276 Added new function silc_change_nick to the Irssi SILC Client.
3277 Affected file irssi/src/silc/core/client_ops.c,
3278 irssi/src/silc/core/silc-nicklist.[ch].
3280 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Check that the public key exists in the GETKEY command before
3283 trying to encode it. Affected file silcd/command.c.
3285 * Print some notifications on received public keys with GETKEY
3286 command in the Irssi SILC Client. Affected files are
3287 irssi/src/fe-common/silc/module-formats.[ch],
3288 irssi/src/silc/core/client_ops.c.
3290 * Use IDENTIFY command to resolve the server information in the
3291 GETKEY command instead of INFO command. Affected file
3292 lib/silcclient/command.c.
3294 * All command reply functions in the client library now calls
3295 the pending command reply callbacks even if an error has
3296 occurred. The server has done this a long time and now it was
3297 time to move the client library to this as well. Now all
3298 errors can be delivered back to the pending command reply
3299 callbacks if necessary. Affected files are
3300 lib/silcclient/command[_reply].[ch].
3302 * Change the nickname on disconnection back to the username
3303 because in reconnect the server will enforce it to it anyway.
3304 Affected file irssi/src/silc/core/silc-servers.c.
3306 * Fixed a config file parsing bug in the Irssi SILC client.
3307 Affected file irssi/src/silc/core/clientconfig.c.
3309 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * When printing the channel mode on JOIN, verify that the
3312 channel key and channel's HMAC are valid. Affected file
3313 irssi/src/silc/core/client_ops.c.
3315 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3318 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3319 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3321 * Removed channel key rekey task deleting from the function
3322 silc_server_save_channel_key. Affected file silcd/server.c.
3323 Added explicit timeout task context instead that is used to
3324 delete the task if we are registering a new task before the
3325 new task has elapsed.
3327 * When channel key rekey occurs the client library now saves
3328 the old channel key for a short period of time (10 seconds) and
3329 is able to use it in case some is still sending channel
3330 messages encrypted with the old key after the rekey. Affected
3331 file lib/silcclient/[idlist.h|client_channel.c].
3333 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3335 * Added check to the silc_server_new_id_real to not accept
3336 new ID if it is the sender's own ID. Affected file is
3337 silcd/packet_receive.c.
3339 * Assure that we do not announce ourself or the one we've
3340 sending our announcements when we're router and are announcing
3341 servers to our primary router. Affected file silcd/server.c.
3343 * Fixed silc_server_command_identify_check_client to assemble
3344 correct WHOIS packet. It send corrupted WHOIS packet and
3345 caused problem with router to router connections. Affected
3346 file silcd/command.c.
3348 Fixed also silc_server_command_whois_check the same way
3349 as for the IDENTIFY command.
3351 * Added new SilcIDListStatus to the server in the SilcIDListData
3352 structure. The status now includes the current status of
3353 the entry (like registered, resolved etc.). Affected file
3354 silcd/idlist.[ch]. Defined a bunch of different status types
3355 as well. This replaced the old boolean registered field as well.
3357 Added resolve_cmd_ident field to the SilcClientEntry structure
3358 too so that if the entry is for example being resolved so
3359 another command may attach to the same pending command reply
3360 without requiring to resolve the same entry again. This concept
3361 should optimize the WHOIS and the IDENTIFY resolving under
3362 heavy load by taking away unnecessary resolving for entries
3363 that are being resolved already.
3365 Added support for adding multiple pending commands for one
3366 command idenfier. Affected file silcd/command[_reply].[ch].
3368 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3369 before deleting the data. Otherwise the hash table will have
3370 freed data in comparison functions. Affected file is
3371 silcd/command_reply.c.
3373 * Fixed silc_idlist_replace_client_id to add the new entry to
3374 the cache with NULL nickname. Otherwise there will be invalid
3375 memory as the nickname after the nickname is freed. Affected
3376 file silcd/packet_receive.c.
3378 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3379 saved into wrong slots because the previous number of entries
3380 was not taken into account. Affected file silcd/idlist.c.
3381 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3383 * If we are router and we receive JOIN notify to a channel that
3384 does not have any users then notified client is marked as the
3385 channel founder, as it is it. The affected file is
3386 silcd/packet_receive.c
3388 * Added to the extended hash table API's table_del_*ext functions
3389 the destructor as argument too, so that the caller can decide
3390 which destructor to use or whether to use destructor at all.
3391 Affected file lib/silcutil/silchashtable.[ch].
3393 * Fixed ID Cache purging. It actually deleted the entries from
3394 the hash table after the data was freed. The hash table ended
3395 up comparing freed memory. The affected file is
3396 lib/silccore/silcidcache.c.
3398 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Fixed Irssi SILC client's KILL command's HELP syntax.
3402 * The USERS command now resolves the detailed user information
3403 if the userinfo field is missing. Affected file is
3404 lib/silcclient/command_reply.c.
3406 * Do not print error in silc_file_read if the read file does
3407 not exist. Just silently return NULL. Affected file is
3408 lib/silcutil/silcutil.c.
3410 * Fixed the silc_log_output to not wine about NULL filename
3411 and to not create some bogus " " filename. Affected file is
3412 lib/silcutil/silclog.c.
3414 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Fixed various printing bugs on the user interface in the
3417 Irssi SILC Client. Minor changes that were forgotten from
3420 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Fixed the configure.in.pre and the compilation and distribution
3423 environment to support the new autoconf 2.52. That version is
3424 now required to compile the CVS trunk.
3426 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3429 to generally parse user@fqdn format strings. Affected file
3430 lib/silcutil/silcutil.c.
3432 * Added nickname_format and nickname_force_format fields to the
3433 SilcClientParams structure. The first one defines the format
3434 for the nicknames that the library will enforce if the receives
3435 multiple same nicknames. The second one is boolean value and
3436 can be used to force the library to always enforce the format
3437 to the nicknames regardles whether there are multiple nicknames
3438 or not. This configurable formatting was employed to flexibly
3439 support accessing multiple nicknames from the user interface.
3440 The userinterface can now set the nicknames to what ever format
3441 they prefer. Affected file lib/silcclient/silcapi.h.
3443 Added function silc_client_nickname_format to the file
3444 lib/silcclient/idlist.c. It performs the nickname formatting.
3446 Added new field `hostname´ to the SilcClientEntry context.
3447 It holds the hostname of the client. Affected file is
3448 lib/silcclient/idlist.h.
3450 * Irssi SILC Client sets the nicknames in nick@hostn format.
3451 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3452 irssi/src/silc/core/silc-core.c.
3454 The WHOIS printing now also shows both the real nickname and
3455 the formatted nickname so that user knows how to access the
3456 user if there are multiple same nicknames cached. Affected
3457 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3458 printing formatting too to take the hostname now as a separate
3459 argument. The Affected file is
3460 irssi/src/fe-common/silc/modules-formats.[ch].
3462 * Changed the silc_client_get_clients_local to accept the formatted
3463 nickname as argument. It accepts the real nickname too but the
3464 formatted nickname can be used to find the true entry from
3465 multiple entries. Affected file lib/silcclient/silcapi.h and
3466 lib/silcclient/idlist.c.
3468 * Added nickname_format_parse field to the SilcClientParams.
3469 It is a callback function provided by the application to parse
3470 the nickname out of the formatted nickname string. The library
3471 calls it to get the nickname from the formatted string. Since
3472 the application generally knows better the format of the nickname
3473 string it parses it instead of the library, even though library
3474 encodes the formatted string. If the callback function is not
3475 provided then the library will use the string as is. The
3476 affected file is lib/silcclient/silcapi.h.
3478 * All the nickname strings passed to the client library in
3479 commands are now expected to be formatted nickname strings.
3480 If the command does not support the formatted nickname string
3481 it will assume that the sent string is the actual nickname.
3482 Affected file lib/silcclient/command.c.
3484 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Added public key authentication support to OPER and SILCOPER
3487 commands in the client library. Affected file is
3488 lib/silcclient/command.c.
3490 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Changed the get_auth_methdod client operation to be asynchronous.
3493 It can be async if the application resolves the authentication
3494 method from the server during the negotiation. Added new
3495 SilcGetAuthMeth completion callback that the application will
3496 call after resolving the authentication method.
3498 Added function silc_client_request_authentication_method that
3499 the application can use to resolve the authentication method
3500 from the server. Added also SilcConnectionAuthRequest callback
3501 that the library will call after the server has replied. The
3502 application can call this function if it does not know the
3503 current authentication method.
3505 Affected files are lib/silcclient/client.c and
3506 lib/silcclient/silcapi.h.
3508 * The Irssi SILC client now automatically resolves the authentication
3509 method incase any configuration information is not present (and
3510 currently there never is). The affected file is
3511 irssi/src/silc/core/client_ops.c.
3513 * Fixed public key authentication from the client library.
3514 Affected file lib/silcclient/protocol.c. Changed also the
3515 protocol specification about the public key authentication in
3516 the connection authentication protocol. The actual data to be
3517 signed is now computed with a hash function before signing.
3519 * Fixed the public key authentication from the server as well.
3520 Affected file silcd/protocol.c.
3522 * Removed the mlock()'s from the memory allocation routines.
3523 Affected file lib/silcutil/silcmemory.c. The ./configure does
3524 not check anymore for the mlock(). Affected file is
3527 * Fixed USERS command in server to allow the execution of the
3528 command for private and secret channels if the client sending
3529 the command is on the channel. Affected file silcd/command.c.
3531 * Fixed silc_client_get_clients_local to return the clients
3532 count correctly. It could return wrong value. Affected file
3533 lib/silcclient/idlist.c.
3535 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3538 types. The assembler optimizations seemed not to like 64-bit
3539 data types. The assmebler optimizations thus are now enabled
3540 also for BSD systems as opposed to only enable them for Linux.
3542 * Do not check for threads at all on BSD systems. Affected
3543 file configure.in.pre.
3545 * Removed -n and -h options from the Irssi SILC Client since
3546 they are not used in silc.
3548 * Fixed the prime generation to assure that the first digit
3549 of the generated random number is not zero since our conversion
3550 routines does not like number strings that starts with zero
3551 digit. If zero digit is seen the random number is regenerated.
3552 This caused some corrupted RSA keys when the zero first digit
3553 was met. Affected file lib/silcmath/silcprimegen.c.
3555 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Fixed WIN32 configuration in the ./configure script.
3558 Fixed to include xti.h on environments that has it.
3559 Patches by Carsten Ilchmann and andrew.
3561 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Changed the silc_id_create_client_id to be collision
3564 resistant. It is now assured that there cannot be created
3565 two same client ID's. I suspect that some weird bugs in
3566 the server were actually caused by duplicate Client IDs.
3567 Affected file silcd/serverid.[ch]. A router receiving
3568 new ID now also assures and informs the sending server
3569 if the ID caused collision.
3571 * Changed the silc_id_create_channel_id to also assure that
3572 there are no collisions.
3574 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Statement about ignoring the Mutual Authentication flag when
3577 performing rekey with PFS was a bit misleading. It is ignored
3578 if it was set in the initial negotiation, it cannot be even
3579 set in the rekey. Fixed in the ke-auth draft. Started the
3580 new versions of the protocol drafts in the doc/.
3582 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Fixed a bug in silc_client_command_identify_save when saving
3585 new channel information. The channel name was no duplicated
3586 and caused crash on exit. Affected file is
3587 lib/silcclient/command_reply.c.
3589 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Fixed the getkey command handling in the server. Send just
3592 empty OK reply to the sender if the key could not be fetched
3593 (but everything else was ok, like the key just was not available).
3594 Changed the public key parameter to optional in the protocol
3595 specs so that empty OK reply can be sent. Affected file
3598 Added a message to Irssi SILC client to tell to user if the
3599 server did not return a public key.
3601 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Fixed a channel key regeneration bug. It registered new
3604 timeout tasks exponentially until all system resources were
3605 used. Affected file silcd/server.c.
3607 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3609 * Added the SILC Document generator to the scripts/silcdoc.
3610 It can be used to generate the Toolkit Reference Manual out
3611 of the source tree. Internally it will also use the RoboDoc
3612 generator now imported in util/robodoc.
3614 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Added couple of return's in rekey protocol if error orccurred
3617 during the protocol. The execution must be terminated.
3618 Affected file silcd/protocol.c. Also, terminate the protocol
3619 always with timeout.
3621 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * The client's Client ID was created initally from the wrong
3624 nickname (it could have been in format nick@host) in the
3625 silc_server_new_client. Affected file silcd/packet_receive.c
3627 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Added some SILC_LOG_ERROR's to various error conditions
3630 if client could not be added to ID cache. Affected files
3631 silcd/packet_receive.c and silcd/server.c.
3633 * When client's sock->user_data is freed, NULL also the
3634 client->router and client->connection pointers. Added check
3635 for these pointers being NULL to various places around the
3636 code. Affected file silcd/server.c.
3638 * Added client->data.registered == TRUE checks to various
3639 places around the code to assure that unregistered client's
3640 are not handled when it is not allowed. Affected file
3643 * Added `bool registered' fields to all
3644 silc_idlist_[server|client]_get_* routines to indicate whether
3645 the fetched client needs to be registered or not. Affected
3646 file silcd/idlist.[ch].
3648 * Add your own entry as registered to the ID cache in the
3649 server. Affected file server.c.
3651 * Fixed a bug in silc_server_new_server. The SilcServer was
3652 set as the new server's context instead of SilcServerEntry.
3653 This naturally caused some weird bugs.
3655 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3657 * Do not delete the channel rekey task when adding it
3658 for in silc_server_create_channel_key.
3660 * Changed the silc_server_create_channel_key to return
3661 TRUE or FALSE to indicate the success of the channel key
3664 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * Fixed MSVC++ project files and added missing files to

3675 * Fixed buffer overflow from Irssi SILC Client. Affected
3676 file irssi/src/fe-common/core/themes.c.
3678 * Fixed double free in client library in the file
3679 lib/silcclient/client.c when disconnecting from server.
3681 * Applied double free patch from cras to Irssi SILC client.
3682 Affected files irssi/src/core/[modules/expandos].c
3684 * Fixed the disconnection handling to Irssi SILC Client.
3685 The application must call silc_client_close_connection
3686 in ops->connect client operation in case of failure of
3687 the connection. Affected file is
3688 irssi/src/silc/core/client_ops.c.
3690 * Do not set sock->protocol to NULL in the function
3691 silc_client_close_connection after executing the protocol's
3692 final callback since the sock might not be valid anymore.
3693 Affected file lib/silcclient/client.c.
3695 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3697 * Do not enable SILC_THREADS if the linking with libpthread
3698 did not happen. Affected file configure.in.pre.
3700 * Added notion to protocol specification that server must
3701 verify the sent authentication payload with CMODE when
3702 setting the channel founder key. Implemented it to the
3703 server. Affected file silcd/command.c.
3705 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Added _EXTRA_DIST SILC distribution variable to the
3708 distributions file. It is used to conditionally add extra
3709 files or directories to the specific distribution. Affected
3710 files ./prepare, Makefile.am.pre and distributions.
3712 Removed the `_' from the start of the distribution names.
3715 * Added README.WIN32 for instructions to compile the Toolkit
3718 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3720 * Fixed a double free in disconnection in the server. Affected
3721 file is silcd/server.c.
3723 * Fixed the lib/silcske/groups.c to work now also with GMP
3724 MP library. The string conversion did not work when using
3725 specific base and the base is indicated in the string as well.
3727 * Created win32/ directory which now includes MSVC++ specific
3728 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3729 It will appear only in the toolkit distribution
3731 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Changed the key material distribution function in case when
3734 the hash output is too short. The data is now concatenated
3735 a bit differently than it used to. Made the change to the
3736 SKE protocol specification.
3738 * Added better GMP detection to configure.in.pre. A patch
3741 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Fixed a minor bug in SKE that might cause some problem on
3744 some platforms. Affected file lib/silcske/silcske.c.
3746 * Added the cookie checking for initiator in the SKE. It checks
3747 that the responder returns the sent cookie unmodified. The
3748 affected file is lib/silcske/silcske.c. Added new SKE
3749 error type INVALID_COOKIE that can be sent during the
3750 negotiation. Fixed some memory leaks as well.
3752 * Added the "invalid cookie" error message to Irssi SILC client's
3755 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3757 * Added `task_max' field to the SilcClientParams to indicate
3758 the maximum tasks the scheduler can handle. If set to zero,
3759 default values are used. Affected file lib/silcclient/silcapi.h.
3761 * Fixed memory leaks in silc_client_close_connection. Affected
3762 file lib/silcclient/client.c.
3764 * Added silc_client_del_client_entry to client library to free
3765 all memory of given client entry. Affected file is
3766 lib/silcclient/idlist.[ch].
3768 * Added new functions silc_client_del_channel and
3769 silc_client_del_server to delete channel and server entries.
3770 Affected file lib/silcclient/[silcapi.h/idlist.c].
3772 * Removed silc_client_del_client_by_id from silcapi.h.
3774 * Fixed the INFO command to return the server's own info
3775 correctly when querying by Server ID. Affected file is
3778 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3780 * Removed the non-blocking settings in WIN32 code in the
3781 silc_sock_[read/write] and added SleepEx instead. Affected
3782 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3783 of input data is now checked with FIONREAD and ioctlsocket.
3785 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Call silc_schedule_task_del_by_context in the
3788 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3789 Affected file lib/silccore/silcprotocol.c.
3791 * Call silc_protocol_cancel for active protocols in the
3792 silc_server_close_connection if the funtion
3793 silc_server_free_sock_user_data has not been called.
3794 Affected file silcd/server.c.
3796 * Generic tasks cannot be deleted using the del_by_fd
3797 task deleting function since generic tasks does not match
3798 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3800 * Added a notion to SILCOPER help file that the SILCOPER works
3801 only on router server, not on normal server.
3803 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Added for WIN32 support for the new scheduler as well.
3806 Affected file lib/silcutil/win32/silcwin32schedule.c.
3808 * Fixed the SHA1 implementation to work on various platforms.
3810 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3813 API. It is part of the scheduler now. Everything else is
3814 as previously but some functions has changed their names.
3815 Checkout the lib/silcutil/silcschedule.h for the interface.
3816 Updated all applications to use the new interface. Affected
3817 files are lib/silcutil/silcschedule.[ch].
3819 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Found a bug in the SKE implementation. The HASH value,
3822 specified by the protocol, was not computed correctly. The
3823 public key of the responder was not added to the computation
3824 even though it is mandatory. Affected file lib/silcske/silcske.c.
3825 This unfortunately causes incompatibilities with older
3826 clients and servers.
3828 * Added WIN32 specific network init and uninit functions:
3829 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3830 the Winsock2. Affected file lib/silcutil/silcnet.h and
3831 lib/silcutil/win32/silcwin32net.c.
3833 * Set the socket always to nonblocking mode on WIN32 after
3834 reading data or writing data. Affected file is
3835 lib/silcutil/win32/silcwin32sockconn.c.
3837 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Fixed various compilation problems under WIN32. Affected
3840 files lib/silcutil/win32/silcwin32thread.c and
3841 lib/silcutil/win32/silcwin32schedule.c.
3843 * Removed all _internal.h #includes from public header
3844 files. Internal headers must never be included from
3847 Removed also the lib/silcske/payload_internal.h file.
3849 * All include files that may be needed (public and some others
3850 included by the public headers) by application developers are
3851 now copied to the ./includes directory. It does not copy any
3852 internal headers. Affected file Makefile.defines.pre and all
3853 Makefile.am's under lib/ and subdirs.
3855 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Do not change the ~/.silc directory's permissions automatically.
3858 Affected file irssi/src/silc/core/clientutil.c.
3860 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3862 * Do not cancel the protocol in silc_server_close_connection
3863 it might cause recursion. Now cancelled in the function
3864 silc_server_free_sock_user_data. Affected file silcd/server.c.
3866 * Fixed the silc_server_remove_clients_by_server to regenerate
3867 the channel keys correctly finally. Added also new function
3868 silc_server_remove_clients_channels to actually do it.
3869 Affected file silcd/server.c.
3871 * Fixed the silc_server_new_channel to not crash by giving
3872 wrong router to the new channel. Affected file is
3873 silcd/packet_receive.c.
3875 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3877 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3878 which is given as argument to the silc_client_alloc now.
3879 It can be used to configure the client and set various parameters
3880 that affect the function of the client.
3882 * The USERS command in server did not check whether the channel
3883 is private or secret. Affected file silcd/command.c.
3885 * Added new argument to the USERS command in protocol specification.
3886 The USERS command now can take the channel name as argument
3887 as well. Added support for this in client and server and
3888 updated the protocol specs.
3890 * Completed the GETKEY command in client. It can be now used
3891 to fetch also servers public key not only some clients.
3892 Affected files lib/silcclient/command[_reply].c.
3894 * Added silc_client_get_server to return server entry by the
3895 server name. Affected files lib/silcclient/silcapi.h and
3898 * Redefined the IDENTIFY command in protocol specification to be
3899 more generic. It now can be used to query information about
3900 any entity in the SILC Network, including clients, servers and
3901 channels. The query may be based either the entity's name
3902 or the ID. Added support for this in both client and server.
3904 Affected files silcd/command.c and lib/silcclient/command.c
3905 and command_reply.c.
3907 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3908 the _from_client and _from_server functions. Affected file
3911 * Added silc_client_get_channel_by_id_resolve to the file
3912 lib/silcclient/silcapi.h to resolve channel information by
3913 its ID. Added also silc_client_get_channel_by_id that
3914 does not resolve it from the server.
3916 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3918 * Added SilcServerEntry context into the client library
3919 to represent one server. The INFO command now allocates
3920 these to save the resolved server info. For now on the
3921 client library will also keep information about servers,
3922 connected and resolved with INFO.
3924 The INFO command now allocates the SilcServerEntry context
3925 and saves the server info there. The COMMAND_REPLY in
3926 the INFO now returns the parameters to application in
3927 same order as defined in the protocol specification.
3929 The entries are cached in the client->server_cache.
3931 * The INFO command is now issued after received the Client ID
3932 from the server. Affected file lib/silcclient/client.c.
3934 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3935 to the application as the mode changer might be server.
3936 It is guaranteed that NULL is not returned anymore to the
3937 application. Affected file lib/silcclient/client_notify.c.
3939 The ID Type is now also passed to the application so that
3940 it can check whether the returned entry is SilcClientEntry
3943 Added new function silc_client_get_server_by_id to return
3944 the server entry by ID. Affected files are the
3945 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3947 * Do not create the channel in the Irssi SILC Client when issuing
3948 the JOIN command but when received the sucessful JOIN command
3949 reply. Otherwise the channel might get created even though we
3950 could not join it. The Affected file is
3951 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3953 * Fixed a channel joining bug in router. The router must also
3954 check the channel modes, invite and ban lists etc. when serving
3955 the JOIN command sent by normal server. Affected file is
3956 silcd/command.c. The router now resolves the client's
3957 information from the server who sent the JOIN command if it
3958 does not know it, and processes the JOIN command only after
3961 * Changed the SilcCommandCb to take new argument; void *context2.
3962 Affected file lib/silccore/silccommand.h
3964 The second argument in the command callbacks in the server now
3965 includes the SilcServerCommandReplyContext if the command was
3966 called as pending command callback from the command reply.
3967 Otherwise it is NULL. When called as pending the status of the
3968 command reply will be checked and if it was erronous the
3969 error will be sent to the original sender of the command.
3970 This way the client always receives the error messages even
3971 though the server was actually the one who received the error
3972 when it resent the command to router, for example. Affected
3973 files silcd/command[_reply].[ch].
3975 * Fixed sending WHOWAS command's error message to client if
3976 the requested client could not be found. It was missing.
3979 * Changed the CMODE and CUMODE commands reply arguments in the
3980 protocol specification. The Channel ID is now sent in both
3981 of the commands to identify the channel. Implemented this
3982 new feature to the client and server. Affected files
3983 lib/silcclient/command_reply.c and silcd/command.c.
3985 * Made better checks for invite and ban lists in the JOIN
3986 command in server. Affected file silcd/command.c.
3988 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3990 * The server now performs the incoming host IP/DNS lookup
3991 using the silc_socket_host_lookup and thus does not block
3992 the server anymore. Affected file silcd/server.c.
3994 * Completed the multi-thread support for SILC Scheduler in
3995 the lib/silcutil/silcschedule.c.
3997 * Fixed the configure.in.pre to detect the pthread correctly
4000 * Fixed a deadlock in silc_task_queue_wakeup in the file
4001 lib/silcutil/silctask.c.
4003 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Added new function silc_schedule_wakeup that is used in
4006 multi-threaded environment to wakeup the main thread's
4007 schduler. It needs to be used when a thread adds a new task
4008 or removes a task from task queues. After waking up, the
4009 scheduler will detect the task queue changes. If threads
4010 support is not compiled in this function has no effect.
4011 Implemented the wakeup mechanism to both Unix and WIN32
4012 systems. Affected files are lib/silcutil/silcschedule.[ch],
4013 lib/silcutil/unix/silcunixschedule.c and the
4014 lib/silcutil/win32/silcwin32schedule.c.
4016 * Added new function silc_task_queue_wakeup to wakeup the
4017 scheduler by the specified task queue. Affected file
4018 lib/silcutil/silctask.[ch].
4020 * The silc_socket_host_lookup_start now wakes up the scheduler
4021 after adding the timeout task. Affected file is
4022 lib/silcutil/silcsockconn.c.
4024 * The silc_socket_host_lookup is synchronous now if the threads
4025 support is not compiled in. However, the callback is still
4026 called asyncronously through the scheduler, anyway. Affected
4027 file lib/silcutil/silcsockconn.c.
4029 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Added new function silc_socket_host_lookup to perform
4032 asynchronous IP and FQDN lookups for the socket connection.
4033 Affected files lib/silcutil/silcsockconn.[ch].
4035 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4037 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4038 that may or may not compile the mutex support in.
4040 Changed the silc_mutex_alloc interface. It allocates the
4041 mutex now to the sent pointer and returns TRUE or FALSE.
4043 Affected file lib/silcutil/silcmutex.h.
4045 * Wrote the SILC Task Queue interface to support multi-threads.
4046 Affected file lib/silcutil/silctask.[ch].
4048 * Wrote the SILC Scheduler to support multi-threads. Affected
4049 file lib/silcutil/silcschedule.c.
4051 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4053 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4054 in lib/silcutil/win32/.
4056 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4058 * Defined SILC Mutex API and SILC Thread API and implemented
4059 them for Unix. Affected files are
4060 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4061 lib/silcutil/unix/silcunixmutex.c and
4062 lib/silcutil/unix/silcunixthread.c.
4064 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4066 * Fixed the silc_server_remove_clients_by_server's channel
4067 key re-generation. The hash table handling was incorrect
4068 and would not work with many channels. Affected file is
4071 * Fixed some memory leaks around the server code.
4073 * Rewrote the silc_server_get_users_on_channel to support IPv6
4074 based Client ID's. Affected file silcd/server.c.
4076 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4077 specification. However, a separate document must be written
4078 to define the detailed signing procedure and the payload
4079 associated with the flag. Defined the flag to the
4080 lib/silccore/silcchannel.h as well.
4082 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Changed the dynamic tables to static size tables in the
4085 lib/silccrypt/silchmac.c.
4087 * Removed GCC dependencies from the code. A patch by cras.
4089 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Do not show the error "Error receiving packet bla bla"
4092 in server if it really was not an error (-2 means that reading
4093 is pending). Affected file silcd/server.c.
4095 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4097 * Fixed a possible crash in silc_server_remove_clients_by_server
4098 in silcd/server.c. Fixed there also some memory leaks.
4100 * Fixed the silc_idlist_replace_client_id. It could replace
4101 wrong key in the hash table. Affected file silcd/idlist.c.
4103 * Do not check whether there are global users on the channel
4104 if the channel->global_users is FALSE. Affected functions
4105 silc_server_remove_from_one_channel and
4106 silc_server_remove_from_channels in silcd/server.c. Also,
4107 do not check if the removed client is local as we can be
4108 sure that global client was not removed from the channel
4109 and checking for global users is not needed.
4111 * The silc_server_remove_clients_by_server now re-generates
4112 the channel keys correctly for those channels that had
4113 clients removed from them. Affected file silcd/server.c.
4115 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Found the reason of random crashes in the server. We weren't
4118 ignoring the SIGPIPE signal (which can be sent in write())
4119 and it crashed the server. Affected file silcd/silcd.c.
4121 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4123 * Assure that sock->user_data is not NULL in the function
4124 silc_server_packet_send in silcd/packet_send.c.
4126 * Disconnect the remote connection if it could not be added
4127 to any ID lists in the server. The affected file is
4130 * Check in silc_server_packet_send[_real/dest] that the
4131 socket is not disconnecting and ignore the data if it is.
4132 Affected file silcd/packet_send.c.
4134 * Define inline to __inline on native WIN32 compilation.
4135 Affected file includes/silcwin32.h.
4137 * Added some explicit type casts for inline code since MSVC
4138 require them. Affected files lib/silcutil/silcbuffer.h,
4139 lib/trq/silcdlist.h and lib/trq/silclist.h.
4141 * Print warning in log files from now on if the packet
4142 decryption fails. Affected file silcd/server.c.
4144 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4146 * Changed the `say' client operation's interface to accept
4147 new `type' argument to indicate the type of the message sent
4148 by the library. The application may filter the library's
4149 messages according the type. The affected file is the
4150 lib/silcclient/silcapi.h.
4152 * Added two new functions to lib/silcclient/silcapi.h:
4153 silc_client_del_client and silc_client_del_client_by_id.
4154 Affected file lib/silcclient/idlist.c.
4156 * Moved the clientincludes.h from includes/ to silc/ and
4157 serverincludes.h from includes/ to silcd/.
4159 * The modes for the CMODE and CUMODE are now passed as
4160 uint32 for application with COMMAND_REPLY. The affected
4161 file is lib/silcclient/command_reply.c.
4163 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * /WHOIS without arguments shows client's own information.
4166 Affected file lib/silcclient/command.c.
4168 * Changed PING to not accept any arguments. The specs
4169 says that client can ping only the connected server so
4170 requiring an argument is not needed. Affected file is
4171 lib/silcclient/command.c.
4173 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4175 * Fixed a fatal bug in private message sending and reception
4176 encryption and decryption when using private message keys.
4177 The implementation was incorrect and did not follow the
4178 specification. It causd that some of the message were
4179 lost since it did not use the sending and receiving keys
4180 as the protocol suggests. This has been fixed and will cause
4181 incompatibilities with older clients when sending private
4182 message encrypted with private message keys. Affected files
4183 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4184 and various other in Irssi SILC Client.
4186 Added `responder' boolean argument to the functions
4187 silc_client_add_private_message_key[_ske] to indicate when
4188 the key is added as responder or initiator of the key
4191 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4193 * Removed the silc_ske_check_version function and created
4194 a SilcSKECheckVersion callback. Added also a function
4195 silc_ske_set_callbacks that is now used to set all SKE
4196 callbacks. The callback functions are not given to
4197 the SKE functions anymore, but this function is used to
4200 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4202 * Added `silc_version' argument to the silc_client_alloc
4203 to define the version of the application for the library.
4204 The library will use the version string to compare it
4205 against the remote host's (usually a server) version
4206 string. Affected file lib/silcclient/silcapi.h
4208 * Added the KE protocol context to Key Agreement context
4209 in client library so that we can abort the SKE if it
4210 is in process when we get timeout. Affected file is
4211 lib/silcclient/client_keyagr.c.
4213 * Do not resolve the client ID forever if it returns in the
4214 first time that such client does not exist. This was done
4215 for example with private message. Affected file is
4216 lib/silcclient/client_prvmsg.c.
4218 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4220 * Do not add regex.h for WIN32. The affected file
4221 includes/silcincludes.h.
4223 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4224 not work yet 100%. It generates the DLL's automatically
4225 when compiling with --with-win32 under cygwin.
4227 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4229 * lib/contrib/regex.c is not compiled on WIN32.
4231 * Added silc_net_get_socket_opt function to the
4232 lib/silcutil/silcnet.h.
4234 * Added includes/silcwin32.h for WIN32 specific includes
4237 * Do not use ptime structure or any of the posix process
4238 functions on WIN32 in lib/silccrypt/silrng.c.
4240 * Added silc_gettimeofday to provide generic function
4241 for struct timeval on all platforms. Added the function
4242 to lib/silcutil/silcutil.h.
4244 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4247 library as they clearly belong there. As a plus side we
4248 can make the actual socket connection routines platform
4251 Added also new generic function silc_socket_read and
4252 silc_socket_write (that used to be silc_packet_[read/write].
4253 The implementation of these are platform specific.
4255 * Added WIN32 specific routines of silc_socket_[read/write]
4256 to lib/silcutil/win32/silcwin32sockconn.c.
4258 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Added preliminary support for native WIN32 compilation under
4261 cygwin (using the -mno-cygwin option for GCC) to the
4262 ./configure.in.pre. The --with-win32 now prepares the
4263 compilation for native WIN32.
4265 * Rewrote the SILC Scheduler interface in the file
4266 lib/silcutil/silcschedule.h. The scheduler is now context
4267 based and does not have anymore any global static scheduler.
4268 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4269 and created lib/silcutil/win32 directory for WIN32 based
4272 * Added Unix specific network routines to the
4273 lib/silcutil/unix/silcunixnet.c and the old
4274 lib/silcutil/silcnet.c includes now only generic routines.
4276 Added WIN32 specific network routines to the
4277 lib/silcutil/win32/silcwin32net.c.
4279 * Added Unix specific utility functions from the
4280 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4282 * Added WIN32 SILC Scheduler to the file
4283 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4286 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4288 * Do not handle JOIN notify in the server if the target client
4289 is not registered (idata->registered == FALSE). The affected
4290 file is silcd/packet_receive.c.
4292 * Update the nickrec->founder in event_cumode in the Irssi SILC
4293 client. Affected file irssi/src/silc/core/silc-channels.c.
4295 * Fixed the CUMODE_CHANGE notify handling in the server when
4296 server and router are announcing their clients on channels.
4297 Now the mode changes are saved and notified correctly. The
4298 affected file is /silcd/packet_receive.c.
4300 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4301 They really did not replace the cache entry in the ID Cache.
4302 Now they do that. Affected file silcd/idlist.c.
4304 * Fixed the KICK notify handling in the Irssi SILC client to
4305 update the channel records so that the kicked client does not
4306 appear to be on the channel. The affected file is
4307 irssi/src/silc/core/silc-channels.c.
4309 * Always update the conn->current_channel when executing command
4310 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4312 * Fixed the KILL notify handling in Irssi SILC client to remove
4313 the killed client on all channels.
4315 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Fixed the silc_parse_command_line to remove extra spaces
4318 from the start and end of the arguments. Affected file is
4319 lib/silcutil/silcutil.c.
4321 * Cancel and free any active protocol in the function
4322 silc_server_close_connection. Affected file silcd/server.c.
4324 * Cancel and free any active protocol in the function
4325 silc_client_close_connction. Affected file is
4326 lib/silcclient/client.c.
4328 * Do not execute the KILL command for clients that are in
4329 history (ie. they are not in the network). Affected file is
4332 * Fixed KILL notify handling, client does not crash anymore.
4333 Affected file irssi/src/silc/core/silc-channels.c.
4335 * Reduced the default packet buffer size from 2048 to 1024 in
4336 lib/silccore/silcpacket.c.
4338 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4339 counter to the SKE context that is incresed when the SKE library
4340 performs async operation outside the library. If the outside
4341 process frees the SKE context and FREED status will be set
4342 and the library will detect after the sync operation that the
4343 libary is freed. The affected files are
4344 lib/silcske/silcske[_status].[ch].
4346 * Resolve the client entry information in the function
4347 silc_client_channel_message to assure that NULL pointer is not
4348 passed as client entry to the application. */
4350 * Fixed the task timeout calculation to assure that there is
4351 never negative timeouts. The affected file is
4352 lib/silcutil/silcschedule.c.
4354 * Fixed the channel user mode notification sending in server.
4355 It was sent point-to-point to the router (or to server by router)
4356 but it needs to be destined to a channel. The routines now
4357 supports sending the channel user mode notifys to the channels
4358 when announcing clients and channels. Affected files are
4359 silcd/server.c and silcd/packet_receive.c.
4361 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4362 It did not actually replace the old channel entry in the cache.
4363 Affected file lib/silcclient/client_notify.c.
4365 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed a possible crash in silc_packet_send_prepare. It now
4368 assures always that there is enough space in the buffer and
4369 at the tail area of the buffer (for MAC).
4371 Fixed the inbound buffer reallocation in silc_packet_read.
4372 It was old code and did not handle the reallocation correctly.
4375 The affected file is lib/silccore/silcpacket.c.
4377 * Fixed buffer overflow in silc_parse_nickname in the file
4378 lib/silcutil/silcutil.c.
4380 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * make install generates new server keys only if there is not
4385 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4387 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4388 Added check that if the NOREPLY is set then we will not send
4389 the away message. This avoids infinite loop of away messages
4390 if both clients are away. The affected file is
4391 lib/silcclient/client_prvmsg.c.
4393 * Fixed client crash if /NICK was given without arguments.
4394 Affected file lib/silcclient/command.c.
4396 * Server does not send the invite list in INVITE command back
4397 to the client if the list was not altered. Added this notion
4398 to the protocol spec as well. Affected file silcd/command.c.
4400 Fixed possible crash in INVITE command by checking the
4401 value of silc_server_get_client_route command.
4403 * Fixed the INVITE notify type handling. The arguments are now
4404 taken in correct order and client does not crash. The affected
4405 file is irssi/src/silc/core/silc-channels.c.
4407 Removed the "Inviting xxx to channel" message from the
4408 client library away and let the application handle it.
4409 Affected file lib/silcclient/command.c. Added that message
4410 to Irssi SILC client's message formats.
4412 * Fixed CMODE command crash in client. It now checks the
4413 amount of arguments correctly and does not crash. The affected
4414 file is lib/silcclient/command.c.
4416 * Do not create new channel automatically in silc_channels_join
4417 but check whether the channel by that name already exists.
4418 Affected file irssi/silc/core/silc-channels.c.
4420 * Do not send the SERVER_SIGNOFF to router if the disconnected
4421 entity was the router. Affected file silcd/server.c.
4423 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4424 SILC client as it was missing from there.
4426 Added the handling of the KICK notify to the Irssi SILC client
4427 as it was missing. Added "you have been kicked" message to
4428 Irssi SILC client's message modules formats.
4430 Added the handing of the KILL notify to the Irssi SILC client
4431 as it was missing. Added the kill message module formats
4434 The affected file is irssi/src/silc/core/silc-channels.c.
4436 * The router did not save the channel mode the server announced.
4437 Affected file silcd/packet_receive.c.
4439 * Fixed a possible crash in INFO command in server. If the
4440 server did not provide the server info it crashed. Affected
4441 file silcd/command.c.
4443 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Fixed the GETKEY command in the server to check also the
4446 global list. Otherwise the GETKEY would not work correctly
4447 in normal SILC server. Affected file silcd/command.c.
4449 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Fixed GETKEY crash, it crashed if the command did not succseed.
4453 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4456 is now real and not just an macro interface to GMP.
4458 Removed the entire GMP from the source tree and imported new
4459 NSS MPI library instead. Reason for removing GMP is that it is
4460 extremely large and compiles extremely slow. The NSS MPI
4461 is only a few files and compiles in less than 10 seconds.
4462 The speed is also about the same as GMP. The MPI is imported
4463 to lib/silcmath/mpi.
4465 If the system has GMP installed we will still use the GMP.
4466 If it is not then the NSS MPI will be compiled.
4468 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Merged a long nickname (127 characters long) crash bugfix from
4471 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4473 * Merged a freed memory reference bugfix from Irssi CVS tree.
4474 Affected file irssi/src/core/commands.c.
4476 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Added the server's public key sving and verification to the
4479 server when performing the SKE. This was missing and the
4480 remote server's (or router's) public key was accepted without
4481 checking whether we have it previously or trust it at all.
4482 Affected file silcd/protocol.c.
4484 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Check in the silc_server_timeout_remote if protocol is active
4487 and make sure that the protocol's final callback is called so
4488 that all memory if freed. Affected file silcd/server.c.
4490 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * silc_server_whois_send_reply crashed the server if the nickname
4493 was 127 characters long. Affected file silcd/command.c.
4495 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Added sanity check to the silc_server_new_client. If the hostname
4498 is provided inside username then check that the provided hostname
4499 really is the same as the resolved one. If the hostname was not
4500 resolved then check it from the public key. Affected file is
4501 silcd/packet_receive.c.
4503 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4504 if the server disconnected us and the connection is not valid
4505 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4507 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4508 the library to the lib/silcutil/silcutil.[ch].
4510 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Close log file after open. Affected file
4513 lib/silcutil/silclog.c.
4515 * Check whether sock == NULL in silc_client_send_packet and return
4516 if it is. Affected file lib/silcclient/silcclient.c.
4518 * Check rec->entry == NULL in the Irssi SILC Client before
4519 sending the channel message. Affecte file is
4520 irssi/src/silc/core/silc-servers.c.
4522 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Merged a splitted window bugfix from Irssi CVS tree. The
4525 affected file is irssi/src/fe-text/textbuffer-view.c.
4527 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4528 It did not print nickname.
4530 * Improved the distributions system a bit.
4532 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4535 irssi/src/fe-text/gui-window.c.
4537 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4538 to in-active server. The affected file is
4539 irssi/src/silc/core/client_ops.c.
4541 * Resolve the client in USERS command reply if the entry does
4542 not have username resolved. The affected file is
4543 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4544 command to WHOIS command to really resolve stuff. The USERS
4545 is not used any more in any critical section so WHOIS can
4546 be used even though it might be slower than IDENTIFY.
4548 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4551 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Changed the protocol API a bit more consistent in the
4554 lib/silccore/silcprotocol.[ch].
4556 * Changed the following headers to ROBODoc format:
4558 lib/silccore/silcpayload.h
4559 lib/silccore/silcprotocol.h
4560 lib/silccore/silcsockconn.h
4562 All core library headers are now formatted.
4564 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Fixed a bug in Irssi SILC client; do not show that you are
4567 server/router operator if you really are not. Affected file is
4568 irssi/src/silc/core/client_ops.c.
4570 * Renamed silc_command_free_payload to silc_command_payload_free.
4571 Affected file lib/silccore/silccommand.h
4573 * Added silcmath.h to include the prototoypes of various routines
4574 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4577 * Changed the following headers to ROBODoc format:
4579 lib/silccore/silcchannel.h
4580 lib/silccore/silccommand.h
4581 lib/silccore/silcid.h
4582 lib/silccore/silcidcache.h
4583 lib/silccore/silcmode.h
4584 lib/silccore/silcnotify.h
4585 lib/silccore/silcpacket.h
4586 lib/silcmath/silcmath.h
4588 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added checking to the server code not to start the server if
4591 ciphers and stuff are not configured properly. Affected files
4592 silcd/serverconfig.[h] and silcd/server.c.
4594 * Changed the layout of the header files of the public interfaces
4595 in the SILC libraries. The new layout supports ROBODoc
4596 documentation tool (and some others) so that it is easy to create
4597 a library reference manual. All the other headers and source
4598 code must still follow the CodingStyle document. Also source
4599 code must not include these ROBODoc stuffs, only the headers.
4600 Furthermore, all public interface headers must now be named
4601 by using `silc' prefix, example: silcapi.h, silccipher.h.
4602 Some files were renamed due to this. All the other headers
4603 must not be used as public interfaces. I will update the
4604 CodingStyle document later. Changed following headers, so far:
4606 lib/silcclient/silcapi.h
4607 lib/silccore/silcauth.h
4608 lib/silccore/silcprivate.h
4609 lib/silccrypt/silcdh.h
4611 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Removed silc_client_packet_send_flush from the client library
4616 as it is not needed. Affected file lib/silcclient/client.[ch].
4618 * Added printing of message of unresolved authentication method
4619 to the Irssi SILC client. Added it to the module formats.
4620 Removed the same message from the client library.
4622 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Added new distribution feature, DISTLABEL. Every distribution
4625 can define own preprocessor label that can be used in the
4626 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4627 file distributions, acconfig.h.pre and prepare.
4629 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added Makefile.defines_int to include the actual definitions
4632 for Makefile.defines.in. Tested the new distribution system,
4633 created distributions and tested installation.
4635 * Added AWAY message printing to the Irssi SILC client. Added
4636 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4638 * Added SCONNECT command to call the SILC's CONNECT command.
4639 Cannot use CONNECT directly since Irssi uses that internally.
4640 Affected file irssi/src/silc/core/silc-servers.c.
4642 Added ACTION local command. It is same as ME command but takes
4643 the channel as mandatory argument.
4645 Rewrote some of the Irssi's help files to suite for SILC
4648 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Added Makefile.defines[.in] that should for now on be included
4651 in all Makefile.am file in the source tree. That file includes
4652 all common compilation definitions for SILC source tree.
4654 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Minor changes to the ./prepare script to change the package
4657 name according the distribution name to the configure.in.
4659 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Created new distribution system. Added file `distributions'
4662 that defines all the distributions that can be created out of
4663 the SILC source tree. The ./prepare script now reads that
4664 file to determine how to prepare the distributions. The
4665 first argument to the ./prepare is the name of the distribution
4666 and second is the version of the distribution. If given
4667 without arguments it creates the default (toolkit) distribution
4668 with the default version (defined in ./prepare).
4670 All Makefile.am files that are subject to the distributions
4671 are now named as Makefile.am.pre. These are ./Makefile.am
4672 and lib/Makefile.am. Others may be changed later.
4674 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added invite list, ban list, some key management and connection
4677 error message printing to module formats in the Irssi SILC client.
4679 * Added new silc_client_set_away_message to set the away message
4680 that is back to the person who sent private message. The
4681 affected file lib/silcclient/silcapi.h and the
4682 lib/silcclient/client_prvmsg.c.
4684 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Fixed the private message sending in the Irssi SILC client,
4687 added local command KEY to the Irssi SILC client.
4689 Added key management and key agreement message formats to the
4690 irssi/src/fe-common/silc/module-formats.[ch].
4692 Added USERS (alias WHO) printing, server/router operator
4693 indication and LIST command printing to the module formats.
4695 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Fixed channel joining notify handling, cumode notify handling
4698 from Irssi SILC client.
4700 * Added SILC specific module-formats to the Irssi SILC client so
4701 that SILC specific message hilighting, colors etc is possible.
4702 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4704 Added channel mode, channel user mode, actions, notices,
4705 whois and whowas printing to the the module-formats.c.
4707 * Fixed a bug in channel deletion in the server. The channel
4708 is not left to the cache even if the channel founder auth mode
4709 is set when there are no users anymore on the channel. Affected
4710 file silcd/server.c.
4712 * The silc_net_localhost now resolves the entire hostname including
4713 the domain name. Affected file lib/silcutil/silcnet.c.
4715 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Changed the ask_passphrase client operation to be ascynchronous.
4718 It has now a completion callback and a context that the
4719 application must call after it has got the passphrase from
4720 the user. Affected files lib/silcclient/silcapi.h,
4721 lib/silcclient/protocol.c, lib/silcclient/command.c and
4724 Added SilcAskPassphrase callback that the application calls
4725 to deliver the passphrase to the library.
4727 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4728 The public key verification and especially a certificate
4729 verification is asynchronous procedure.
4731 Added new SILC_SKE_STATUS_PENDING status to indicate the
4732 request is pending and a callback will be called to finalize
4735 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4736 indicate that remote end did not send its public key (or
4737 certificate), even though we require it. Added check for this
4738 condition in the SKE. This was a security bug, now fixed.
4740 Defined new SilcSKEVerifyCbCompletion callback that is called
4741 when the verification process is completed.
4743 The affected files lib/silcske/silcske_status.h and
4744 lib/silcske/silcske.[ch].
4746 * Changed the verify_public_key client operation to be async
4747 as well. Defined SilcVerifyPublicKey callback that is used to
4748 indicate the success of the public key verification process.
4750 Changed the server and client to use the new async client
4753 * Changed the Irssi SILC client's internal scheduler to be called
4754 twice as many times as it used to be. As a result the client
4755 should be a bit faster now. Affected file is
4756 irssi/src/silc/core/silc-core.c.
4758 * Added support to Irssi SILC client of asynchronous public key
4759 verification and passphrase inquiry. Affected file is
4760 irssi/src/silc/core/silc-core.c.
4762 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Do not say "You have left channel %s" in client library.
4765 Moved it to the application. Affected files are
4766 lib/silcclient/command.c and silc/client_ops.c.
4768 * Fixed silc_client_get_clients. Command context was not
4769 duplicated and was freed memory in the callback. Affected
4770 file lib/silcclient/idlist.c.
4772 * Do not say "you are now talking..." on JOIN command in the
4773 client library. The appliation must handle it.
4775 * Do not say ".. changed topic to" in command reply in the
4776 client libary. The application must handle it.
4778 * Fixed TOPIC command sending in the client library.
4780 * Fixed a memory leak in silc_client_command_free in the file
4781 lib/silcclient/command.c.
4783 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Imported a modified version of Irssi client to the source tree.
4786 The Irssi will be used to create a new client called
4787 Irssi SILC. Imported to irssi/.
4789 Added silc_core_init_finish function to the Irssi. Affected
4790 file irssi/configure.in.
4792 A lot changes in the Makefile.ams around the irssi tree.
4794 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Do not rehash if the new size is same as the old size of the
4797 hash table, in the silc_hash_table_rehash*. The affected file
4798 lib/silcutil/silchashtable.c.
4800 * Replaced hash_table_del_by_context calls from the server
4801 (when channel->user_list and client->channels) to the
4802 hash_table_del as it is sufficient and faster.
4804 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Added silc_hash_table_list, silc_hash_table_get and the
4807 SilcHashTableList structure to provide an alternative way to
4808 traverse the hash table. The affected files are
4809 lib/silcutil/silchashtable.[ch].
4811 * Changed the server's idlist routines to use the hash table
4812 routines to optimize the code.
4814 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Replaced the client entry's `channel' list and channel entry's
4817 `user_list' list to hash tables for optimized lookup. Changed
4818 the code to use the hash table interface around the code.
4819 Affected file lib/silcd/idlist.[ch].
4821 * Added `auto_rehash' boolean argument to the function
4822 silc_hash_table_alloc to indicate whether the hash table should
4823 auto-rehash when it thinks is appropriate time. It will
4824 increase the hash table size if the there is twice as much
4825 entries in the table than the size of the table, and will
4826 decrease the size if there are twice as less entries than
4827 the size of the table.
4829 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4833 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * silc_idcache_purge_by_context deletes the entry now by context
4836 as it is supposed to do. Affected file lib/silccore/idcache.c.
4838 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4839 client is not anymore valid (WHOWAS givens the info) and not
4840 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4842 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Removed the `data' and `data_len' arguments from the ID Cache
4845 interfaces and added `name' argument. ID Cache does not handle
4846 anymore the binary data only a names associated with given ID.
4848 * When hashing a Client ID with silc_hash_id the entire ID is
4849 not hashed anymore, instead only the hash of the Client ID is
4850 hashed. This way we can access the Client ID from the cache
4851 with Client ID but with the hash of the ID (which is a hash of
4852 the nickname) as well without any difference in performance.
4854 Added also silc_idcache_find_by_id_one_ext to do one on one
4855 searching when we have the actual ID. Added also function
4856 silc_hash_client_id_compare. The affected files are
4857 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4859 * When hashing the name associated with a ID it is always done
4860 in lowercase. This way we can access the cache without worrying
4861 about case-sensitivity, even though, for example nicknames are
4864 * Fixed a bug in server with channel message sending. It put
4865 wrong ID type as destination ID. The affected file
4866 silcd/packet_send.c.
4868 * silc_idcache_del_by_context now deletes from all hash tables
4869 by context. Affected file lib/silccore/idcache.c.
4871 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Changed the client library to use the new ID Cache interface.
4874 Changes around the source tree.
4876 * Added silc_hash_table_rehash_ext to rehash with specific
4877 hash function. Affected file lib/silcutil/silchashtable.[ch].
4879 * Added silc_hash_string_compare to compare two strings in the
4880 hash table. Affected file lib/silcutil/silcutil.[ch].
4882 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added new function silc_idcache_del_by_context into the
4885 lib/silccore/idcache.[ch].
4887 * Changed the server's ID list routines to use the new ID Cache
4888 interface. Changes around the source tree.
4890 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added silc_hash_table_del[_by_context]_ext functions in to the
4893 lib/silcutil/silchashtable.[ch].
4895 Removed silc_hash_table_find_all* routines and added new
4896 silc_hash_table_find_foreach to replace them.
4898 Added silc_hash_table_replace_ext function as extended
4899 replacing function. Separated the simple hash table interface
4900 from the extended hash table interface in the file
4901 lib/silcutil/silchashtable.h.
4903 * Fixed minor bugs and changed it to use some of the new
4904 hash table functions in lib/silccore/idcache.c
4906 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Added new function silc_hash_table_find_all to return all keys
4909 in the hash table by the specified key. As the hash table is
4910 collision resistant it also makes it possible to have several
4911 duplicate keys in the hash table. This function may be used to
4912 find all of the keys from the hash.
4914 Added user_context arguments to the SilcHashFunction,
4915 SilcHashCompare and SilcHashDestructor to deliver user specified
4918 Added new fuctions silc_hash_table_find[_all]_ext to do
4919 extended lookup with specified hash and compare functions and
4920 specified user contexts.
4922 Added new function silc_hash_table_add_ext to add the key
4923 with specified hash function and user context.
4925 Added new function silc_hash_table_foreach to traverse all
4926 entrys in the hash table. Added SilcHashForeach callback
4929 Added new function silc_hash_table_del_by_context to delete
4930 the entry only if the context associated with the key matches.
4932 Affected files are lib/silcutil/silchashtable.[ch].
4934 * Removed silc_hash_[server/client/channel]_id and added just
4935 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4936 silc_hash_id_compare to compare two ID's using as the hash table
4937 comparison function. Added also silc_hash_data to hash
4938 binary data and silc_hash_data_compare to compare it.
4940 * Removed silc_idlist_find_client_by_hash as it is not needed
4941 anymore. Affected file silcd/idlist.[ch].
4943 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4944 to use internally the SilcHashTable. The new ID Cache is a lot
4945 faster than the old one. Some of the ID Cache interface was also
4946 rewritten and obsolete and stupid functions were removed.
4948 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added entry_count field to the SilcHashTable to keep the number
4951 of the entries in the table. Implemented the function
4952 silc_hash_table_rehash. Added new function
4953 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4955 Fixed a minor bug in silc_hash_table_free.
4957 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4958 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4959 into the lib/silcutil/silcutil.[ch].
4961 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Implemented a collision resistant hash table into the
4964 lib/silcutil/silchashtable[ch]. See the header and the source
4965 for the SilcHashTable API.
4967 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Merged dotconf version 1.0.2 into lib/dotconf.
4971 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Do not compile anything in lib/silcsim/* if the SIM support
4974 is not enabled. The tree should now compile without problems
4977 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Compiled the SILC under cygwin. Compiled and tested briefly
4980 without problems. More tests needed. The SIMs didn't compile
4983 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4985 * Fixed possible crash in silc_get_username in the
4986 lib/silcutil/silcutil.c.
4988 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Fixed a va_arg in silc/client_ops.c.
4992 * Oops, RC5 routines were named AES and caused some problems
4993 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4995 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added new SilcIDIP structure into the lib/silccore/id.h and
4998 replaced the old `ip' fields from all SILC ID's to that type.
4999 This is a step towards IPv6 support.
5001 The silc_id_get_len takes now the ID as an extra argument.
5002 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5003 both IPv4 and IPv6 based ID's.
5005 The affected files are lib/silccore/id.[ch] and other files
5006 around the tree using these routines.
5008 * Removed the ID length arguments in server from various
5009 silc_server_send_notify_* routines -> they are not needed
5012 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Fixed memory leak in silc_encode_pem_file in the file
5015 lib/silcutil/silcutil.c.
5017 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Check minor version as well in the SKE. Affected files are
5020 silcd/protocol.c and lib/silcclient/protocol.c.
5022 * Added --identifier option to the server so that an identifier
5023 can be when creating the public key for the server. Affected
5024 file is silcd/silcd.c.
5026 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5027 lib/silccrypt/silcpkcs.c.
5029 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Register default ciphers and stuff when using -C option with
5032 the server. Affected file sildc/silcd.c.
5034 * Put back the servers public key filename format, it is better
5035 than the new one. For now, the client keys are saved with the
5036 new filename format. The affected file silc/client_ops.c.
5038 * Implemented the Cipher API for the rest of the ciphers that
5039 did not implement it or implemented it the wrong way.
5041 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Register default ciphers and stuff when using the -S option
5044 in the client. Affected file silc/silc.c. Same also when
5045 creating new key pair with -C option.
5047 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Fixed the silc_verify_public_key client operation function to
5050 save the public keys differently. The fingerprint is now
5051 used as filename and not the hostname. This way also the
5052 client keys are saved uniquely and not with hostnames. The
5053 affected file is silc/client_ops.c.
5055 * Trimmed the silc_hash_fingerprint function to remove extra
5056 whitespaces from the end of the fingerprint. The affected
5057 file is lib/silccrypt/silchash.c.
5061 * Added silc_cipher_register_default function to register all
5062 default ciphers. It can be used when configuration files
5063 does not exist and the application does not want any specific
5064 ciphers in any specific order.
5066 The SilcDList is now used as silc_cipher_list dynamically
5067 allocated cipher list. Removed the static list all together
5068 and now all ciphers must be allocated to the dynamic list.
5069 The silc_cipher_alloc routine was changed to check only the
5072 All silc_cipher_* routines that used to return int returns
5075 The affected files lib/silccrypt/silccrypt.[ch].
5077 * The same thing was done to silc_hash_* as for silc_cipher_*
5078 routines. Affected files lib/silccrypt/silchash.[ch].
5080 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5081 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5082 Added also silc_pkcs_[un]register[_default] functions.
5083 Removed the data_context from the PKCS API.
5085 * Added silc_hmac_register_default function to register default
5086 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5087 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5088 to unregister all hmacs at once.
5090 * Register the default ciphers, hash functions, PKCSs and HMACs
5091 if client's configuration file does not exist. The affected
5094 * The client did not load the hash functions from the SIM
5095 modules at all. Added support for this. Affected file is
5096 silc/clientconfig.c.
5098 * When decoding public key with silc_pkcs_public_key_decode, check
5099 the supported algorithm only if PKCS are registered. Affected
5100 file lib/silccrypt/silcpkcs.c. The same was done with the
5101 silc_pkcs_private_key_decode.
5103 * Fixed the SILC List routines to keep the list always in order.
5104 It used to change the list's order when traversing the list but
5105 not it preserves the order. Affected file lib/trq/silclist.h.
5107 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added the client library to use the SilcSocketConnection's
5110 reference counter (by silc_socket_dup) to prevent the bug that
5111 the socket object may be freed underneath async operation.
5113 * The name resolv library checking fixes in the configure.in.pre.
5116 * Created new version of the protocol drafts for future
5117 development. The -03 drafts are the ones that will be changed
5118 in the trunk now and the -02 will remain as they are.
5120 * Send list of CUMODE notifys to the router when announcing
5121 the channel users to the router. Affected file silcd/server.c.
5122 If the router receiving channel founder CUMODE for a channel
5123 that already has channel founder it will send CUMODE notify
5124 to the sender to remove the channel founder rights from the
5125 announced client. Affected file silcd/packet_receive.c.
5127 * The CUMODE notify may now use Server ID as well as the entity
5128 who changes the mode. Updated protocool specs.
5130 * Updated INSTALL and README files.
5132 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * New web pages in the http://silc.pspt.fi. The pages was
5139 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Implemented the [DenyConnectin] config section in the server.
5142 Added silc_server_config_denied_conn to check whether incoming
5143 connection is denied. Affected file silcd/serverconfig.[ch].
5145 * Do not check the ports when checking the incoming configuration
5146 data if the port is 0, meaning any. Affected file is
5147 silcd/serverconfig.c.
5149 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Fixed buffer overflow in silc_string_compare in the file
5152 lib/silcutil/silcutil.c.
5154 * Fixed double free in silc_server_command_leave in the file
5157 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Fixed the version checking in the server. Affected file is
5162 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Fixed the configuration data fetching when accepting new
5165 connections in the server. Affected file silcd/server.c.
5167 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Added `sender_entry' argument to the function
5170 silc_server_packet_relay_to_channel so that we can check
5171 whether some destination actually belongs to the same route
5172 the sender belongs (ie, we must not resend the packet to the
5173 sender). Affected file silcd/packet_send.[ch].
5175 * Added `servername' field to the SilcClientEntry in the server
5176 to hold the name of the server where client is from. Affected
5177 file is silcd/idlist.h.
5179 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Moved the channel message encrypting in the router betwen
5182 router connections from silc_server_channel_message to the
5183 silc_server_packet_relay_to_channel since we want to check
5184 whether we have anybody channel before encrypting anything.
5185 Affected files silcd/packet_[receive/send].c.
5187 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Fixed the [AdminConnection] server config section to support
5190 multiple entries. Affected file silcd/serverconfig.c.
5192 * Added support into the server to check the validity of the
5193 incoming connection before executing any KE or authentication
5196 * The connection configuration is now saved to the KE and
5197 connection auth protocol contexts and not fetched anymore in
5198 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5200 * The local hosts listenning address and port is also resolved
5201 now when starting the server. We want to have the socket object
5202 to include the real address and port for the listener. Added
5203 new function silc_net_check_local_by_sock into the files
5204 lib/silcutil/silcnet.[ch].
5206 * Fixed a broadcast bug in server -> do not broadcast if we
5209 * Fixed a routing bug. Do not route broadcast packets ever.
5210 Broadcast packets must be processed always and not routed since
5211 they may be destined to some other host than yourself and thus
5212 would get routed without no good reason. Affected file is
5215 * Added function silc_server_config_is_primary_route to check
5216 whether primary router connection has been configured (a router
5217 configuration that we are initiating). If there is not, we
5218 will assume that there is only two routers in the SILC network
5219 and we will use the incoming router connection as our primary
5220 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5222 * Changed the order of the broadcasting. Broadcast _after_ the
5223 packet has been processed not before. Affected file is
5226 * Fixed a [ClientConnection] parsing bug. The port was never
5227 parsed correctly thus resulting to port 0. Affected file
5228 silcd/serverconfig.c.
5230 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5231 argument and did not set the broadcast packet flag. Affected
5232 file silcd/packet_send.c. Fixed same bug in the function
5233 silc_server_send_notify as well.
5235 * If we receive NEW_ID packet for our own ID in the server, ignore
5238 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Removed the nickname from the Private Message Payload.
5243 Updated the code and the protocol specs.
5245 * Updated protocol specs for submitting to the IETF.
5247 * Tweaked the Random Number Generator a bit. Affected file
5248 lib/silccrypt/silcrng.c. Exported a new function
5249 silc_rng_[global]_add_noise which can be used to add more
5252 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Do not parse packets with different timeout when protocol
5255 is active -> may cause problem with rekey. Affected file
5258 * When server receives signoff notify it must not create
5259 new channel key if the client is on any channels since the
5260 sender of the signoff notify will create it.
5262 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added printing of error messages during SKE protocol from the
5265 failure packet sent by server during SKE. Affected file
5268 * Removed the client's failure_callback handling with timeout
5269 and handle it immediately when received.
5271 * The SKE library returned wrong type in SUCCESS and FAILURE
5272 packets. They must be 32 bit MSB not 16 bit MSB.
5274 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Ok, rewrote the logic of the re-key and now it seems to work.
5277 I tested it on high traffic with frequent re-keys without
5278 problems. Added hmac_receive (and renamed hmac to hmac_send)
5279 in SilcClientConnection in lib/silcclient/client.h and
5280 in SilcIDListData in silcd/idlist.h. Also, removed the
5281 SilcPacketParserContext's cipher and hmac fields as they are
5282 not needed anymore and actually caused some problems when
5283 the ciphers and hmac's changed underneath the packet parser.
5285 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * If re-key protocol is active then process the incoming packets
5288 synchronously since we must assure that icoming packets encrypted
5289 with the old key is processed before the new keys is set to
5290 use. This is true other packets than for REKEY packets.
5291 Affected file silcd/server.c. The same was done to client library
5292 as well, affected file lib/silcclient/client.c.
5294 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Fixed bug in client and server to accept the force send if
5297 the packet is send from silc_[server/client]_packet_process
5298 function. Otherwise the packets are never delivered, oops.
5300 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Disable force sending of packets when REKEY protocol is active.
5303 We must assure that no packet is sent directly when rekey is
5304 performed. All packets must be sent through packet queue.
5305 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5306 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5307 function is silc_[server/client]_packet_send_real to check
5310 * Replaced the SIM paths from example config files to
5311 /usr/local/modules. Also, make install creates now
5312 /usr/local/silc/logs directory to hold all the SILC server
5315 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Made the configure.in.pre work on Solaris. Patch by salo.
5319 * Made all ciphers compatible with non-x86 machines. Defined
5320 CBC mode macros into lib/silccrypt/ciphers_def.h.
5322 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Fixed the make install.
5326 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * When MAC computation fails the silc_packet_decrypt returned 0
5329 even though it was supposed to return -1. Fixed this. The
5330 affected file is lib/silccore/silcpacket.c.
5332 * Do not replace the config files in /etc/silc (in make install)
5333 if they already exist. Affected file ./Makefile.am.
5335 * Do not send re-key packets immediately but through packet queue.
5336 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5338 * Changed silc_net_check_host_by_sock to return FALSE if the
5339 IP/DNS could not be resolved. Though, it returns the IP address
5340 now even if it could not resolve it (but returns also FALSE).
5341 Affected file lib/silcutil/silcnet.[ch].
5343 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Added silc_pkcs_decode_identifier to decode the public key's
5346 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5347 Added also silc_pkcs_free_identifier. Added also new context
5348 SilcPublicKeyIdentifier.
5350 * Added -S option to the silc client. It is used to dump the
5351 contents of the specified public key file.
5353 * Changed the PKCS api to return the public key length when
5354 setting the public key.
5356 * Fixed a fatal bug in the public and private key file loading.
5357 Affected file lib/silccrypt/silcpkcs.c.
5359 * Execute the packet parsing for client with zero (0) timeout
5360 if the protocol is active. Affected file silcd/server.c.
5362 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Made the key generation options to the silcd program. Added
5365 -C option, equivalent to client's option.
5367 * Added new [ServerKeys] config section to the server. It
5368 configures the server's public and private key.
5370 * Defined generic Public Key Payload into the protocol
5371 specification to send specific type of public keys and
5374 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5375 public key or certificate.
5377 * Implemented the GETKEY command to the server and to the
5378 client library and on user interface.
5380 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Made preliminary `make install' work.
5384 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Added SilcServerRekey context into silcd/idlist.h.
5388 * Added the PFS support as defined in the specification to the
5389 SKE protocol. Affected files lib/silcske/*.c.
5391 * Added `ske_group' field to the SilcServerRekey context to hold
5392 the number of the SKE group that is used with PFS in re-key.
5393 Affected file silcd/idlist.h.
5395 * Added PFS re-key support to the server. Affected file is
5398 * Added silc_protocol_cancel to cancel execution of the next
5399 state of the protocol. Affected file is
5400 lib/silccore/silcprotocol.[ch].
5402 * Added the re-key support with and without PFS to the client
5403 library. Re-key is performed once in an hour, by default.
5405 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5406 Added silc_client_rekey_callback and silc_client_rekey_final.
5407 Affected files are lib/silcclient/protocol.[ch] and
5408 lib/silcclient/client.[ch].
5410 * Removed the `hmac_key' and `hmac_key_len' fields from the
5411 SilcClientConnection structure; not needed. Affected file is
5412 lib/silcclient/client.h.
5416 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Do not ask whether user wants to use the negotiated private key
5419 for private messages, just use it. Affected file is
5420 silc/local_command.c.
5422 * Added `send_enc_key' and `enc_key_len' fields to the
5423 SilcIDListData structure since they are needed in the re-key
5424 phase. Affected file is silcd/idlist.[ch].
5426 * Implemented the simple re-key protocol into the server.
5427 Affected files silcd/server.c and silcd/protocol.[ch]. The
5428 re-key will be performed once in an hour, by default.
5430 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5431 Added silc_server_rekey, silc_server_rekey_callback and
5432 silc_server_rekey_final.
5434 * Removed Tunneled flag from the protocol. Updated the code
5435 and the specifications.
5437 * Adde `pfs' field to the SilcIDListData to indicate whether
5438 the PFS is to be performed in the re-key. Affected file is
5441 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5444 int64 of at least the xintXX size. If void * is less that 4
5445 bytes uint32 * will be used. Defined bool as boolean.
5447 * Changed _ALL_ unsigned long and unsigned int to uint32,
5448 unsgined short to uint16 in the source tree.
5450 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5451 not handle clients that has entry->data.registered == FALSE.
5452 They are not in the network anymore. Affected file is
5455 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Implemented the sending of the SERVER_SIGNOFF notify in the
5458 server. Affected file is silcd/server.c.
5460 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5461 Added also silc_notify_payload_encode_args into the
5462 lib/silccore/silcnotify.[ch].
5464 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5465 Affected file silcd/packet_receive.c.
5467 * Implemented the SERVER_SIGNOFF notify handling in the client
5468 library. Affected file lib/silcclient/client_notify.c. Also,
5469 implemnted the printing of the SERVER_SIGNOFF info to the
5470 application. Affected file silc/client_ops.c.
5472 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5473 if the deleting was successful. Affected file silcd/idlist.[ch].
5475 * Added support for public key authentication in the connection
5476 authentication protocol in the client library. Affected file
5477 lib/silcclient/protocol.c.
5479 * Changed the server's silc_idlist_get_clients_by_* interface
5480 to support already allocated array so that new entries may be
5481 added to pre-allocated array. Affected file silcd/idlist.[ch].
5482 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5483 and command replies.
5485 * All command reply functions in the server now calls the
5486 pending command callback even if error occured. This way the
5487 error will be delivered to the client as well. Affected files
5488 silcd/command.c and silcd/command_reply.c.
5490 * Fixed INFO command to return local server's info if no server
5491 was provided. Affected file lib/silcclient/command.c.
5493 * Removed RESTART command for good. Updated the code and the
5496 * Rewrote parts of the task system. It is a bit simpler now.
5497 Removed unsued task priorities. The affected files are
5498 lib/silcutil/silctask.[ch].
5500 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Moved the USERS printing from the library to the application.
5503 Affected files lib/silcclient/command.c and silc/client_ops.c.
5505 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Added channel key re-key support. The re-key is perfomed
5510 only by the router and is done once in an hour. Added `rekey'
5511 field to the SilcChannelEntry in the server. Affected files
5512 silcd/server.c and silcd/idlist.h.
5514 * Added silc_task_unregister_by_context into the file
5515 lib/silcutil/silctask.[ch].
5517 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added SILC_UMODE_GONE mode to indicate when the client is not
5520 present in the SILC network. Added also support to the local
5521 command AWAY that will set this mode. Added support of showing
5522 "xxx is gone" in WHOIS command. The USERS command shows the
5523 gone status as well.
5525 * Fixed setting server and router operator privileges in the
5526 server's UMODE command. Affected file silcd/command.c.
5528 * Merged the SKE KE1 and KE2 payloads into one payload. The
5529 new KE payload is equivalent to the old KE2 payload.
5531 Cleaned up the SKE Start Payload parsing. It now uses the
5532 simple buffer unformatting to do the parsing. A lot faster
5535 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5536 to the SKE that is used to indicate whether both of the SKE
5537 parties should perform authentication. By default only the
5538 responder performs authentication. By setting this flag also
5539 the initiator must do authentication. By default it is unset
5540 since in normal SKE case, client to server connection, only
5541 the responder should do authentication. When doing SKE between
5542 two clients both should perform authentication. Updated the
5543 code and the protocol specs.
5545 * A little fix to IDENTIFY command in the server. Search the
5546 client first by hash not nickname. Affected file is
5549 * Fixed the silc_client_close_connection to support closing
5550 the client to client connections wihtout deleting too much
5551 data. Affected file lib/silcclient/client.c.
5553 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5554 are received if protocol used to be active but is not anymore
5555 the application would crash due to NULL pointer dereference.
5556 Affected files silcd/server.c and lib/silcclient/client.c.
5558 * Added `hash' field to the SilcClientConnection to include
5559 the hash function negotiated in the SKE protocol.
5561 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5562 to set the channel founder authentication data. A client can
5563 claim the founder rights later by providing the authentication
5564 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5565 This way the channel founder can regain the channel founder
5566 privileges even it is left the channel. This works only on
5567 local server and the client must be connected to the same
5568 server to be able to regain the founder rights. Updated the
5569 protocol specs accordingly.
5571 Added support to the CMODE command in the client to set the
5572 founder auth data. Read the README to see how to set it.
5574 Added support to the CUMODE command to claim the founder
5575 rights. Read the README to see how to do it.
5577 Added support for the founder authentication to the Channel
5578 Entry in the server. Affected file silcd/idlist.h.
5580 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5581 server's CMODE command. Affected file silcd/command.c.
5583 * Added the following new functions into lib/silccore/silcauth.[ch]:
5584 silc_auth_get_method and silc_auth_get_data.
5586 * The server now saves the remote hosts public key to the
5587 SilcIDListData pointer. Affected file silcd/protocol.c.
5589 * The normal server now does not remove the channel entry from
5590 the cache if the founder authentication data is set. It used
5591 to remove it if the founder was the last one on the channel on
5592 the server and left the channel. The auth data is saved and
5593 if the channel is re-joined later the old entry is used with
5594 the old auth data. Affected files silcd/command_reply.c and
5597 * Removed the `pkcs' field from the SilcIDListData structure
5598 in the server; it is not used. Affected file silcd/idlist.h.
5600 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Fixed packet processing on slow links. Partial packets were
5603 never re-processed because the incoming data buffer was cleared
5604 by the application. Application must not directly clear the
5605 sock->inbuf, the packet processing routines handle it. Fixed
5606 this in client library and in server.
5608 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Fixed the WHOIS and IDENTIFY send reply function to really
5611 check whether to send list or just one entry. Affected file
5614 * Cleaned up the LEAVE command's channel key distribution. The
5615 affected file silcd/command.c.
5617 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5618 can enforce the channel mode as well. In that case the ID
5619 includes the ID of the server. The code now enforces the
5620 mode change if the router have different mode than the server.
5622 * The notify client operation with CMODE_CHANGE notify can now
5623 return NULL client_entry pointer if the CMODE was not changed
5624 by client. Application must check for this.
5626 * Added <Server ID> argument to INFO command to support server
5627 info fetching by Server ID.
5629 * Added silc_server_announce_get_channel_users to get assembled
5630 packets of channel users of the specified channel. Affected
5631 file silcd/server.[ch].
5633 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5634 was freed underneath the ID Cache.
5636 * Re-announce clients when the server received CHANNEL_CHANGE
5637 notify from the router. Affected file silcd/packet_send.c.
5639 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5642 crashed since it did not handle the fact that there is no cipher
5643 called "3" and didn't check the error condition. Now fixed.
5645 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5646 flag. It can be used to send message requests.
5648 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Implemented the RESTART command in the client.
5652 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5653 notice type messages. Added notice printing to the user
5656 * The channel keys are not re-generated if the channel's mode
5657 is PRIVKEY, ie private key on the channel exists. Affected
5658 files silcd/server.c and silcd/command.c.
5660 * Fixed a little bug in channel message delivery when channel
5661 private keys are set in the server. Affected file is
5662 silcd/packet_send.c.
5664 * Changed the setting on channel->on_channel = TRUE from the
5665 silc_client_save_channel_key to the JOIN command reply. The
5666 key payload is not received if the private channel key is set.
5667 Affected file lib/silcclient/command_reply.c and the
5668 lib/silcclient/client_channel.c.
5670 * When the CMODE_CHANGE notify is sent and the channel private
5671 key mode is removed the channel key must be re-generated in
5672 other cells as well. Added this support for the router in the
5673 silcd/packet_receive.c.
5675 * Added new local command NOTICE to send notice message on
5676 channel. Affected file silc/local_command.[ch].
5678 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Added new local command ME to the client. It is used to send
5681 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5682 some action. Affected file silc/local_command.[ch].
5684 * Changed channel_message and private_message client operations
5685 to deliver the message flags to the application. Added also
5686 the `flags' arguments to the silc_client_send_channel_message
5687 and silc_client_send_private_message functions. Affected file
5690 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Redefined the Private Message Payload to support private message
5693 keys and to support the new private message flags. Updated
5694 the protocol specs. Flags makes it possible to have for example
5695 CTCP style messages.
5697 * Added new type SilcPrivateMessagePayload and defined an API
5698 for it in the lib/silcclient/silcprivate.[ch].
5700 * Tested private message private keys successfully. Tested the
5701 private message key set, unset and list commands with the new
5704 * Redefined the Channel Message Payload to include the channel
5705 message flags (equal with private message flags) to support
5706 for example CTCP style messages.
5708 * Defined some of the message (for channel and private message)
5709 flags. Updated the protocol specs and added the flags to the
5710 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5712 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Added SilcKeyAgreementStatus type to the key agreement routines
5715 to indicate the current status and error if one occured.
5716 The status types are defined in the lib/silcclient/silcapi.h.
5718 * Added new local command KEY that is used to set and unset private
5719 keys for channels, set and unset private keys for private messages
5720 with remote clients and to send key agreement requests and
5721 negotiate the key agreement protocol with remote client. The
5722 key agreement is supported only to negotiate private message keys,
5723 it currently cannot be used to negotiate private keys for channels,
5724 as it is not convenient for that purpose.
5726 * Fixed a minor pending callback setting bug in the function
5727 silc_client_get_client_by_id_resolve, now the function works.
5728 Affected file lib/silcclient/idlist.c.
5730 * Added function silc_net_get_local_port to get local bound
5731 port by socket. Added to lib/silcutil/silcnet.[ch].
5733 * Added `sockets' and `sockets_count' fields to the SilcClient
5734 object. They hold the sockets of the listenning sockets in
5735 the client. Listenning sockets may be for example the key
5736 agreement server. Affected file lib/silcclient/client.[ch].
5737 Added functions the silc_client_add_socket and the
5738 silc_client_del_socket. They are exported to the application
5741 * Added ~./silc/clientkeys to support other client's public keys.
5743 * Renamed verify_server_key client operation to verify_public_key
5744 and added one argument to indicate the type of the connection
5745 (server, client etc.).
5747 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Added silc_server_connection_auth_request to handle the
5750 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5751 silcd/packet_receive.[ch].
5753 * Added silc_server_send_connection_auth_request into the
5754 silcd/packet_send.c to send the connection auth request packet.
5756 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5759 * Fixed the public key authentication in responder side in the
5760 server. The `auth_data' pointer includes the SilcPublicKey
5761 not the path to the public key. Affected file silcd/protocol.c.
5763 * Implemented the public key authentication in the initiator side
5764 in the server. Affected file silcd/protocol.c.
5766 * Removed the [RedirectClient] config section from the server
5767 configuration. Is not needed and I don't want to implement it.
5769 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Cleaned up the CMODE command in the server. It now works
5772 correctly and supports all the modes defined in the protocol.
5773 Affected file is silcd/command.c.
5775 * Added `hmac_name' field to the SilcChannelEntry in the server
5776 to hold the default HMAC of the channel. It can be set when
5777 creating the channel (with JOIN command). Affected files
5780 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5781 type to indicate the change of the current cipher and hmac
5782 on the channel. Client can safely ignore the <cipher> argument
5783 (if it chooses to do so) since the CHANNEL_KEY packet will
5784 force the channel key change anyway. The <hmac> argument is
5785 important since the client is responsible of setting the new
5786 HMAC and the hmac key into use.
5788 * Fixed the CMODE command in the client library as well.
5790 * Tested CMODE command in router environment successfully.
5792 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Show the version of the remote client (or server) when connecting
5795 to the server. It is logged to the log file. Affected file
5796 is silcd/protocol.c.
5798 * Fixed the KILLED notify handling in the client library. The
5799 client must be removed from all channels when receiving the
5802 Also, do not remove the client entry when giving the KILL
5803 command but when the KILLED notify is received.
5805 * Removed silc_idlist_find_client_by_nickname from the server.
5806 Not needed anymore. Affected files silcd/idlist.[ch].
5808 * Implemented the CHANNEL_CHANGE notify type handling to the
5809 server. Affected file silcd/server.c.
5813 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Added silc_server_send_notify_invite to send the INVITE
5816 notify between routers.
5818 * Implemented the INVITE command correctly to the server.
5820 * Implemented the INVITE notify type handling in the server.
5822 * Implemented the INVITE command to the client library and on the
5825 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Added function silc_server_get_client_resolve to find the
5828 client entry by ID from all ID lists and then resolve it
5829 (using WHOIS) if it cannot be found. Affected file is
5832 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Implemented the BAN command to the client library.
5836 * The JOIN command in the server now checks the invite list
5839 * Changed the silc_command_reply_payload_encode_va and the
5840 silc_command_payload_encode_va to support that if argument is
5841 NULL it ignores and checks the next argument. Affected file
5842 lib/silccore/silccommand.c.
5844 * Added silc_server_send_notify_ban to send the BAN notify
5845 type between routers.
5847 * Chaned the silc_notify_payload_encode to support that if
5848 argument is NULL it ignores and checks the next argument.
5849 Affected file lib/silccore/silcnotify.c.
5851 * Tested ban lists in router environment successfully.
5853 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Implemented BAN command to the server, in silcd/command.[ch].
5857 * Removed the BAN and INVITE_LIST modes from the CMODE command
5860 * Added function silc_string_match to regex match two strings.
5861 Affected files lib/silcutil/silcutil.[ch].
5863 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Redefined parts of the SilcChannelEntry in the server to support
5866 the new ban and invite lists.
5868 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Redefined the INVITE command. The same command can be used to
5871 invite individuals to the channel but also to manage the invite
5872 list of the channel (to add to and remove from the invite list).
5873 Updated the protocol specs.
5875 * Added new command SILC_COMMAND_BAN that can be used to manage
5876 the ban list of the channel. Updated the protocol specs.
5878 * Removed the channel modes: the SILC_CMODE_BAN and the
5879 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5880 in the CMODE command. The equivalent features are now available
5881 using INVITE and BAN commands. Updated the protocol specs.
5883 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5884 in the network about change in the current ban list. The notify
5885 type is not used by the client.
5887 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5888 support the invite lists.
5890 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added new function silc_string_regexify that converts string
5893 including wildcard characters into regex string that can
5894 be used by the GNU regex library. Added into the file
5895 lib/silcutil/silcutil.[ch].
5897 Added silc_string_regex_combine to combine to regex strings
5898 into one so that they can be used as one regex string by
5899 the GNU regex library. Added into the file
5900 lib/silcutil/silcutil.[ch].
5902 Added silc_string_regex_match to match two strings. It returns
5903 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5905 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Imported GNU regex to the soruce tree into lib/contrib.
5908 Fixed some compiler warning from the regex.c.
5910 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Fixed MOTD command in the server to work in router environment.
5914 * Fixed the MOTD command in the client library to support
5915 the server argument in the command.
5917 * Added `nickname_len' argument to the silc_idlist_add_client
5918 in the server, as the `nickname' argument may be binary data
5921 * Added silc_idlist_get_channels to return all channels from
5924 * Implemented LIST command to the server. Affected file is
5927 * Implemented the LIST command to the client library and on the
5930 * Added [<user count>] argument to the LIST command reply.
5931 With private channels the user count is not shown.
5933 * Updated TODO and README.
5935 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * The client entry's data.registered must be TRUE even with
5938 global client entry on global client list. The data.registered
5939 is used to check whether the client is anymore in the network,
5940 for example with WHOWAS command so it must be valid.
5942 * Fixed the WHOWAS command in the server. It now actually works
5943 in router environment. Added function into silcd/command_reply.c
5944 silc_server_command_reply_whowas_save.
5946 * Added silc_idlist_purge function to the silcd/idlist.c
5947 to periodically purge the ID Cache.
5949 * Fixed INFO command in the server. It works now in router
5950 environment. Added <server name> argument to the INFO command
5951 reply. Updated the protocol specs.
5953 * Fixed minor bug in silc_idcache_purge to not purge if the
5954 expire value is zero.
5956 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5957 they were buggy because of the WHOWAS information.
5959 * Fixed local command MSG to handle the async resolving of
5960 the remote client properly. It used to fail the first MSG.
5961 Affected file silc/local_command.c.
5963 * Added `data_len' field to SilcIDCache context.
5965 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Update TODO. Todo in commands in the server.
5969 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5972 used by routers as broadcast packet to inform other routers
5973 about the changed user mode.
5975 Implemented the notify handling in the server. Affected file is
5976 silcd/packet_receive.c. Added the function
5977 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5979 * Added new generic Channel Payload and deprecated the New Channel
5980 Payload. The New Channel Payload is now the generic Channel
5983 * Added new argument `mode' to the silc_server_send_new_channel
5984 as it is required in the Channel Payload now.
5986 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5987 and created a new and real SilChannelPayload to represent the
5988 new generic Channel Payload. Implemented the encode/decode
5989 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5991 * Added silc_server_get_client_channel_list to return the list
5992 of channels the client has joined for WHOIS command reply.
5993 Affected file silcd/server.[ch].
5995 * Implemented the channel list sending in the WHOIS command reply
5996 in server and in the client.
5998 Implemented the channel list displaying on the user interface
5999 as well. Affected file silc/client_ops.c.
6001 * Added silc_channel_payload_parse_list to parse list of Channel
6002 Payloads. It returns SilcDList list of SilcChannelPayloads.
6003 Client for example can use this function to parse the list of
6004 channels it receives in the WHOIS command reply. The caller
6005 must free the list by calling silc_channel_payload_list_free.
6006 Affected files lib/silccore/silcchannel.[ch].
6008 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Added one new argument <user mode> to the WHOIS command reply
6011 to return the mode of the user in SILC. Updated the protocol
6014 Implemented it to the server and client.
6016 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Fixed the mode printing on the user interface on joining.
6019 Affected file silc/client_ops.c.
6021 * Implemented the UMODE command and user modes in general to the
6022 client library and to the user interface.
6024 * Implemented the UMODE command to the server.
6026 * The server now sends UNKNOWN_COMMAND error status if client sends
6027 unknown command. Affected file silcd/command.c.
6029 * All server commands now handle the command identifier the right
6030 way when sending the command reply to the client. The client can
6031 use to identify the command replies with the identifier.
6033 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added silc_server_get_client_route to resolve the route to
6036 the client indicated by the client ID. Affected file is
6039 * Added silc_server_relay_packet as general function to relay
6040 packet to arbitrary destination. This deprecates functions
6041 like _send_private_message_key, _relay_notify etc. Affected
6042 file is silcd/packet_send.[ch].
6044 Removed silc_server_send_key_agreement,
6045 silc_server_send_private_message_key and
6046 silc_server_packet_relay_notify functions from the file
6047 silcd/packet_send.[ch].
6051 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6052 server. Affected file silcd/packet_receive.[ch].
6054 * Implemented the KILL command to the client. Implemented the
6055 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6056 Affected files lib/silcclient/command[_reply].c and
6057 lib/silcclient/client_notify.c. Implemented the KILL notify
6058 printing in the user inteface.
6060 * Fixed a lot silc_parse_nick memory leaks from the client
6061 library in the file lib/silcclient/command.c.
6063 * Changed the silc_server_send_notify_on_channels's `sender'
6064 argument from SilcSocketConnection to SilcClientEntry to
6065 check the sender as entry and not as connection object and not
6066 to send to the client provided as argument. The affected file
6067 is silcd/packet_send.[ch].
6069 * The notify packets that are destined directly to the client used
6070 to not to be processed by the server. Now changed that and the
6071 server processes all notify packets. After relaying the packet
6072 to the client the notify packet is processed in the server.
6074 * The silc_server_free_client_data now checks whether there is
6075 pending outgoing traffic for the client and purges the data to
6076 the network before removing the client entry.
6078 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6081 an client is killed from the SILC Network. Updated the protocol
6084 Added new function silc_server_send_notify_killed to the
6085 silcd/packet_send.[ch].
6087 * Added function silc_server_packet_relay_notify to relay notify
6088 packets that are destined directly to a client. In this case
6089 the server does not process the notify packets but merely relays
6090 it to the client. Affected file silcd/packet_send.[ch].
6092 Added also silc_server_packet_process_relay_notify to check
6093 whereto relay the notify. Affected file is
6094 silcd/packet_receive.[ch].
6096 * Implemented the KILL command to the server.
6100 * Added the backup schema desgined last fall to the protocol
6101 specs for everyone to see. The specification is in the
6102 *-spec-xx.txt draft and the packet type definitions for the
6103 backup routers is in *-pp-xx.txt draft. Thusly, added also
6104 new packet type SILC_PACKET_CELL_ROUTERS.
6106 * A big security problem in the implementation discovered. The
6107 signoff of an client did not cause new channel key generation
6108 which it of course should've done. The channel keys must be
6109 always re-generated when client leaves (or signoffs) the channel.
6110 The silc_server_remove_from_channels funtion now handles
6111 the channel key re-generation.
6113 * Added `sender' argument to the silc_server_send_notify_on_channels
6114 to not to send the client provided as argument. Affected file
6115 silcd/packet_send.[ch].
6117 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Implemented OPER and SILCOPER commands into the server and
6122 * Added silc_auth_verify and silc_auth_verify_data to verify
6123 the authentication directly from the authentication payload.
6124 It supports verifying both passphrase and public key based
6125 authentication. Affected file lib/silccore/silcauth.[ch].
6127 * Added `hash' field to the SilcIDListData structure. It is the
6128 hash negotiated in the SKE protocol. Affected file is
6131 * Slight redesigning of the SilcAuthPayload handling routines.
6132 Do not send SilcPKCS but SilcPublicKey as argument.
6134 * Implemented the public key authentication support to the
6135 serverconfig. The public key is loaded from the provided path
6136 and saved as authentication data to void * pointer. Thus,
6137 changed the unsigned char *auth_data to void *auth_data;
6139 * Fixed SHUTDOWN command to send the reply before the server
6140 is shutdown. :) Affected file silcd/command.c.
6142 * Fixed fatal bug in CONNECT command. The hostname was invalid
6143 memory and server crashed. Affected file silcd/command.c.
6145 * Fixed fatal bug in CLOSE command. The server_entry became
6146 invalid but was referenced later in the command. Affected file
6149 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Fixed fatal bug in failure packet handling. Server ignored
6152 the failure and thus crashed when it came.
6156 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6159 that the command may be executed only once in (about) 2 seconds.
6160 The old SILC_CF_LAG flag is same but allows command bursts up
6161 to five before limiting.
6163 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6164 server code. Various commands now includes the CF_LAG_STRICT
6165 flag to disallow any kind of miss-use of the command.
6167 * Fixed the silc_buffer_unformat to not to allocate any data
6168 if the length of the data is zero. It used to allocate the
6169 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6171 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Changed the format of AdminConnection configuration section
6174 in the server. Added username of the admin to the format.
6175 Affected files silcd/serverconfig.[ch].
6177 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6178 to return admin configuration data by host, username and/or
6181 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Implemented WHOWAS command to the server. Added the functions:
6185 silc_server_command_whowas_parse,
6186 silc_server_command_whowas_send_reply,
6187 silc_server_command_whowas_from_client and
6188 silc_server_command_whowas_from_server
6190 * Added <Client ID> argument to the WHOWAS command reply. Updated
6191 the protocol specs accordingly.
6193 * Implemented WHOWAS command and command_reply to the client
6196 Implemented the WHOWAS printing on the user interface.
6198 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added new argument to the WHOWAS command reply, the real name.
6201 It is an optional argument. Updated the protocol specs.
6203 * Added SilcIDCacheDestructor callback that is registered when
6204 the SilcIDCache is allocated. The callback is called when
6205 an cache entry in the ID Cache expires, or is purged from the
6206 cache. Added into lib/silccore/idcache.[ch].
6208 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6209 to destruct the client entries when the cache entry expires.
6210 Other ID Cache's in server and in the client library ignores
6213 * If the ID Cache entry's `expire' field is zero then the entry
6214 never expires. Added boolean `expire' argument to the
6215 silc_idcache_add function in the lib/silccore/idcache.[ch].
6216 If it is TRUE the default expiry value is used.
6218 * Added silc_server_free_client_data_timeout that is registered
6219 when client disconnects. By default for 5 minutes we preserve
6220 the client entry for history - for WHOWAS command.
6222 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Added support to the server to enforce that commands are not
6225 executed more than once in 2 seconds. If server receives
6226 commands from client more frequently, timeout is registered
6227 to process the commands. Affected file silcd/command.c.
6228 Added new function silc_server_command_process_timeout.
6230 * Changed NICK_NOTIFY handling in client library to check that
6231 if the client's nickname was changed, so there is no need to
6232 resolve anything from the server.
6234 * Removed error printing from the WHOIS and IDENTIFY commands.
6235 If error occurs then it is ignored silently in the client library.
6236 The application, however, may map the received error to
6237 human readable error string. The application currently maps
6238 the NO_SUCH_NICKNAME error to string.
6240 * Made the command status message public to the application. Moved
6241 them from lib/silcclient/command_reply.c to
6242 lib/silcclient/command_reply.h. The application can map the
6243 received command status to the string with the
6244 silc_client_command_status_message function.
6246 * Added check to the server to check that client's ID is same
6247 as the Source ID in the packet the client sent. They must
6250 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Added dist-bzip hook to the Makefile.am to make bzip2
6253 compressed distributions.
6255 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Server now enforces the maximum length for the nickname and
6258 the channel as protocol specification dictates. 128 bytes for
6259 nickname and 256 bytes for channel name.
6261 * Moved the WHOIS printing to the application. The client libary
6262 does not print out the WHOIS information anymore, the application
6263 must do it. Renamed silc_client_command_reply_whois_print to
6264 the silc_client_command_reply_whois_save.
6266 The client's idle time is also sent to the application now, and
6267 the idle is shown on screen.
6269 * Added silc_client_command_reply_identify_save to save the
6270 received IDENTIFY entries.
6272 * Do not check for channel private keys in message sending and
6273 reception if the channel does not have the PRIVKEY mode set.
6274 Affected file lib/silclient/client_channel.c.
6276 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6279 just surfaced after chaning the JOIN procedure.
6281 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Added silc_client_get_clients_by_list to get client entries
6284 from Client ID list, that is returned for example by JOIN
6285 and USERS command replies. The application should use this
6286 function for example when JOIN command reply is received to
6287 resolve the clients already on the channel (library does not
6288 do that anymore as USERS command reply is not used in the JOIN
6289 procedure anymore). Affected files lib/silcclient/silcapi.h and
6290 lib/silcclient/idlist.c.
6292 * JOIN command reply and USERS command reply returns now SilcBuffer
6293 pointers instead of unsigned char pointers when returning
6294 the client list and mode list.
6296 * Added <Client ID> argument to the JOIN command reply, mainly
6297 for the server to identify for which client the command was
6298 originally sent. Updated protocol specs accordingly.
6300 * Added SilcDlist private_key pointer to the SilcChannelEntry
6301 in the client to support the channel private keys. Affected
6302 file is lib/silcclient/idlist.h.
6304 * Added SilcChannelPrivateKey argument to the function
6305 silc_client_send_channel_message so that application can choose
6306 to use specific private ke if it wants to. If it is not provided,
6307 the normal channel key is used, unless private keys are set.
6308 In this case the first (key that was added first) is used
6309 as the encryption key.
6311 * Implemented the support for channel private key handling.
6312 Implemented the following functions:
6314 silc_client_add_channel_private_key,
6315 silc_client_del_channel_private_keys,
6316 silc_client_del_channel_private_key,
6317 silc_client_list_channel_private_keys and
6318 silc_client_free_channel_private_keys
6320 Affected file lib/silcclient/client_channel.c.
6322 * Added the support for the private keys in the channel message
6323 sending and encryption and in the message reception and
6324 decryption. Affected funtions are
6325 silc_client_send_channel_message and silc_client_channel_message.
6327 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added SKE's key verify callback to the client library's
6330 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6332 * Removed the statement that server (or router) must send USERS
6333 command reply when joining to the channel so that the client
6334 knows who are on the channel. Instead, the client list and
6335 client's mode list is now sent in the JOIN command reply to the
6336 client who joined channel. This is better solution.
6338 * Added function silc_server_get_users_on_channel and function
6339 silc_server_save_users_on_channel to the silcd/server.[ch].
6341 * Removed function silc_server_command_send_users from the
6344 * Do not show topic on the client library anymore. The topic is
6345 sent in the command reply notify to the application and the
6346 application must show the topic now.
6348 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added client searching by nickname hash into the IDENTIFY and
6351 WHOIS commands in the server as they were clearly missing from
6352 them. Affected file is silcd/command.c.
6354 * Fixed a bug in private message receiving in the client library.
6355 The remote ID was freed and it wasn't supposed, now it is
6358 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Minor fix to the channel payload; allocate the data area, as it
6361 needs to be of specific length.
6363 * If the key agreement port is zero then the operating
6364 system will define the bound port. Affected files are
6365 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6367 * Added new function silc_channel_payload_decrypt into the file
6368 lib/silccore/silcchannel.[ch].
6370 * Moved the channel message etc, check from silc_packet_decrypt
6371 to applications. The library calls now a generic
6372 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6373 when the packet is either normal or special. This was done to
6374 allow more wide range of checking that was not allowed when
6375 the code was in library. Now applications can do virtually any
6376 checks to the packet and return to the library the decision how
6377 the packet should be processed. Affected files are
6378 lib/silccore/silcpacket.[ch].
6380 Added silc_server_packet_decrypt_check to the server and
6381 silc_client_packet_decrypt_check to the client library.
6383 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6384 to send with specified source and destination information.
6386 * Channel message delivery between routers was broken after the
6387 channel key distribution was fixed earlier. The channel key
6388 was used be to distributed to other routers as well which is not
6389 allowed by the protocol. Now this is fixed and channel keys
6390 really are cell specific and the channel message delivery between
6391 routers comply with the protocol specification.
6393 * Fixed various commands in server to check also the global list
6394 for the channel entry and not just the local list. The affected
6395 file silcd/command.c.
6397 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Added assert()s to buffer formatting and unformatting routines
6400 to assert (if --enable-debug) when error occurs. Affected
6401 file: lib/silcutil/silcbuffmt.c.
6403 * Changed to auto-reconnect to check whether the remote host is
6404 router and register the re-connect timeout if it is. It used
6405 to check that whether we are normal server, but router must do
6406 auto-reconnect with another router as well. Affected file
6409 * Removed the [<key len>] option from CMODE command as the cipher
6410 name decides the key length, nowadays. See the defined ciphers
6411 from the protocol specification.
6413 * Added [<hmac>] option to the CMODE command to define the HMAC
6414 for the channel. Added SILC_CMODE_HMAC channel mode.
6416 * Added [<hmac>] option for the JOIN command so that user can
6417 select which HMAC is used to compute the MACs of the channel
6420 * Added Hmac field to the Channel Message Payload. The integrity
6421 of plaintext channel messages are now protected by computing
6422 MAC of the message and attaching the MAC to the payload. The
6423 MAC is encrypted. Now, it is clear that this causes some
6424 overhead to the size of the packet but rationale for this is that
6425 now the receiver can verify whether the channel message decrypted
6426 correctly and also when private keys are set for the channel the
6427 receiver can decrypt the packet with several keys and check from
6428 the MAC which key decrypted the message correctly.
6430 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6431 lib/silccrypt/silccipher.[ch].
6433 * Added silc_hash_len to return the digest length into the
6434 lib/silcrypt/silchash.[ch].
6436 * Rewrote parts of Silc Channel Payload interface in the
6437 lib/silccore/silcchannel.[ch]. The encode function now also
6438 encrypts the packet and parse function decrypts it.
6440 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Fixed a minor formatting bug in the SKE's key material processing.
6443 It actually might have processed the keys wrong way resulting
6446 * Redefined the mandatory HMAC algorithms and added new algorithms.
6447 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6448 and hmac-md5 truncated to 96 bits. The mandatory is now
6449 hmac-sha1-96. Rest are optional (including the one that used
6450 to be mandatory). Rationale for this is that the truncated HMAC
6451 length is sufficient from security point of view and can actually
6452 make the attack against the HMAC harder. Also, the truncated
6453 HMAC causes less overhead to the packets. See the RFC2104 for
6456 * Added new [hmac] configuration section. The SKE used to use
6457 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6458 is of course wrong. The official names that must be proposed in
6459 the SKE are the ones defined in the protocol specification
6460 (hmac-sha1-96 for example). The user can configure any hmac
6461 using any hash function configured in the [hash] section. At
6462 least, the mandatory must be configured.
6464 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6466 * Added HMAC list to the SKE proposal list. It has now both
6467 hash algorithm list and HMAC list. This makes the protocol
6468 incompatible with previous versions. The SKE now seems to work
6469 the way it is supposed to work, for the first time actually.
6471 * Defined plain Hash algorithms to the protocol specification.
6474 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Implemented support for key agreement packets into the server.
6477 Added functions silc_server_key_agreement and
6478 silc_server_send_key_agreement. Other than these functions,
6479 server has nothing to do with this packet.
6481 * Added support for private message key packets into the server.
6482 Added functions silc_server_private_message_key and
6483 silc_server_send_private_message_key.
6487 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6488 called in the protocol's final callback instead in the END
6489 protocol state. This makes a little more sense and in the same
6490 time in client we can use the same protocol routines for normal
6491 key exchange and to key agreement packet handling as well.
6493 * Added to both client's and server's KE protocol context the
6494 SilcSKEKeyMaterial pointer to save the key material. We will
6495 bring the key material to the protocol's final callback by doing
6496 this. The final callback must free the key material.
6498 * Added SKE's packet_send callback into client's KE protocol
6499 context so that the caller can choose what packet sending function
6500 is used. This way we can use different packet sending when
6501 doing normal SKE when doing key agreement packet handling (in
6502 the key agreement packet handling we do not want to encrypt
6505 * Implemented the responder side of the key agreement routines
6506 in the client. The client can now bind to specified port and
6507 accept incoming key negotiation. The key material is passed
6508 to the application after the protocol is over.
6510 * Implemented the processing of incoming Key Agreement packet
6511 in the client. Added function silc_client_key_agreement to
6514 * Implemented the intiator side of the key agreement routines
6515 in the client. The client can now initiate key agreement with
6516 another remote client. The key material is passed to the
6517 application after the protocol is over.
6519 * Created client_keyagr.c to include all the key agreement
6522 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6523 SILC_TASK_CALLBACK except that it is not static.
6525 * Created client_notify.c and moved the Notify packet handling
6526 from the client.[ch] into that file.
6528 * Created client_prvmsg.c and moved all private message and
6529 private message key routines from the client.[ch] into that file.
6531 * Create client_channel.c and moved all channel message and
6532 channel private key routines from the client.[ch] into that file.
6534 * Changed silc_client_get_client_by_id_resolve to resolve with
6535 WHOIS command instead of IDENTIFY command, in the file
6536 lib/silclient/idlist.c.
6538 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Implemented the SKE's responder side to the Client library.
6542 * When FAILURE is received to the protocol do not trust it
6543 blindly. Register a timeout to wait whether the remote closes
6544 the connection as it should do it, only after that process the
6545 actual failure. This was changed to both client and server.
6547 * Added client_internal.h to include some of the structures
6548 there instead of client.h in lib/silcclient/.
6550 * Added function silc_task_unregister_by_callback to unregister
6551 timeouts by the callback function.
6553 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Some "Incomplete WHOIS info" errors has been appearing on the
6556 log files. Took away the entry->userinfo check from WHOIS
6557 reply sending. The entry->userinfo is now " " if client did not
6558 provide one. I thought this was fixed earlier but something
6559 is wrong still. Let's see if the error still appears.
6561 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6563 * Fixed a minor bug in the login when the channel key is
6564 re-generated in the server. It used to generate the key in
6565 wrong order and thus caused problems in the channel traffic.
6567 * Fixed a minor bug in channel key distsribution after
6568 KICK command. The key was not sent to the router even though
6571 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Added silc_ske_process_key_material_data as generic routine
6574 to process any key material as the SILC protocol dictates. The
6575 function is used by the actual SKE library but can be used by
6576 applications as well. This relates to the private message keys
6577 and the channel private keys since they must be processed the
6578 same way the normal SILC session keys. The protocol dictates
6579 this. Affected files: lib/silcske/silcske.[ch].
6581 Added also silc_ske_free_key_material to free the
6582 SilcSKEKeyMaterial structure.
6584 * Defined silc_cipher_set_key function to set the key for
6585 cipher without using the object's method function. The affected
6586 files: lib/silccrypt/silccipher.[ch].
6588 * Implemented silc silc_client_add_private_message_key,
6589 silc_client_add_private_message_key_ske,
6590 silc_client_del_private_message_key,
6591 silc_client_list_private_message_keys and
6592 silc_client_free_private_message_keys functions in the
6595 Added functions silc_client_send_private_message_key to send
6596 the Private Message Key payload and silc_client_private_message_key
6597 to handle incoming Private Message Key payload.
6599 * Added Cipher field to the Private Message Key payload to set
6600 the cipher to be used. If ignored, the default cipher defined
6601 in the SILC protocol (aes-256-cbc) is used.
6603 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Removed lib/silcclient/ops.h file.
6607 Redefined parts of the SILC Client Library API. Created new
6608 file silcapi.h that deprecates the ops.h file and defines the
6609 published Client Library API. Defined also private message key
6610 API and channel private key API into the file.
6612 This is the file that the application must include from the
6613 SILC Client Library. Other files need not be included by
6614 the application anymore.
6616 * Added new key_agreement client operation callback and also
6617 defined the Key Agreement library API for the application.
6619 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6622 is used by clients to request key negotiation between another
6623 client in the SILC network. If the negotiation is started it
6624 is performed using the SKE protocol. The result of the
6625 negotiation, the secret key material, can be used for example
6626 as private message key.
6628 Implemented the Key Agreement payload into the files
6629 lib/silccore/silauth.[ch].
6631 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Redefined ciphers for the SILC protocol. Added some new ciphers
6634 and defined the key lengths for the algorithms. Changed the
6635 code accordingly. The default key length is now 256 bits.
6637 * Fixed SKE key distribution function silc_ske_process_key_material
6638 when the key length is more than 128 bits. The default key
6639 length in SILC is now 256 bits.
6641 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6642 to indicate unsupported algorithm.
6644 * Renamed rijndael.c to aes.c and all functions as well.
6646 * Fixed a long standing channel key setting bug in client library.
6647 Weird that it has never surfaced before.
6649 * Fixed bug in channel deletion. If the entire channel is removed
6650 then it must also delete the references of the channel entry
6651 from the client's channel list as the client's channel entry and
6652 the channel's client entry share same memory.
6654 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Implemented CONNECT and SHUTDOWN commands in the client.
6658 * Implemented CLOSE command to the client.
6660 * Added the function silc_idlist_find_server_by_name into the
6661 files silcd/idlist.[ch].
6663 Added the function silc_idlist_find_server_by_conn into the
6664 files silcd/idlist.[ch].
6666 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * DIE command was renamed to SHUTDOWN. Updated the both code
6671 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6672 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6674 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6677 * Added function silc_server_create_connection function to create
6678 connection to remote router. My server implementation actually
6679 does not allow router to connect to normal server (it expects
6680 that normal server always initiates the connection to the router)
6681 so the CONNECT command is only good for connecting to another
6684 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6687 or some other client was kicked from the channel.
6689 Implemented the handling of the notify type to both client
6692 Implemented silc_server_send_notify_kicked to send the KICKED
6693 notify. It is used to send it to the server's primary router.
6695 * Implemented the KICK command into server and client.
6697 * Added `query' argument to the silc_idlist_get_client function
6698 to indicate whether to query the client from server or not if
6701 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6702 to indicate that the client is not channel founder.
6706 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Removed the rng context from SilcPacketContext structure and
6709 changed that the packet routine uses the Global RNG API.
6711 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Added support for quit message that client can "leave" on the
6714 channel when it quits the SILC. It is ditributed inside the
6715 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6717 Added silc_server_free_client_data that will take the
6718 signoff message as argument.
6720 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6722 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Updated parts of the protocol specification to keep it up
6727 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6729 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6730 payloads in one packet.
6732 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6733 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6734 use now the new List flag.
6736 * Also deprecated the following packet types: REPLACE_ID,
6737 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6739 * Added list support for Notify packet in server.
6741 * Added silc_server_send_notify_channel_change to send the
6742 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6743 the silc_server_send_replace_id.
6745 * Added silc_server_send_notify_nick_change to send the
6746 NICK_CHANGE notify type. Deprecates the function
6747 silc_server_send_replace_id.
6749 * Added silc_server_send_notify_join to send the JOIN notify type.
6750 Deprecates the function silc_server_send_new_channel_user.
6752 * Added silc_server_send_notify_leave to send LEAVE notify type.
6753 Deprecates the function silc_server_send_remove_channel_user.
6755 * Added silc_server_send_notify_cmode and
6756 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6757 types. Deprecates the silc_server_send_set_mode function.
6759 * Added SERVER_SIGNOFF notify type to indicate that server has
6760 quit. This means that all clients on the channel from that
6761 server will drop. This can be also used when netsplit happens.
6763 Deprecated REMOVE_ID packet type since it is not needed anymore
6766 Added silc_server_send_notify_server_signoff to send the
6767 SERVER_SIGNOFF notify type. Deprecates the function
6768 silc_server_send_remove_id.
6770 Added also silc_server_send_notify_signoff to send the
6771 SIGNOFF notify type.
6773 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6774 SILC protocol from this day on. Changed the protocol
6775 specification as well.
6777 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6778 notify type. It is used between routers to notify about
6779 topic changes on a channel.
6781 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6784 * Partly updated the protocol specification to comply with the
6785 changes now made. It is still though a bit outdated.
6787 * The JOIN notify type now takes one extra argument <Channel ID>.
6788 The packet used to be destined to the channel but now the
6789 JOIN type may be sent as list thus it is impossible to
6790 destine it to any specific channel. By adding this argument
6791 it is again possible.
6793 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Added CREDITS file. The CHANGES and CREDITS file will appear
6796 in the distribution as well.
6798 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6801 types in the server's silcd/packet_receive.c.
6803 * Implemented CMODE and CUMODE to work in router environment.
6805 * Fixed minor encoding and decoding buglet from the
6806 lib/silccore/silcmode.c.
6808 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6811 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6813 * Changed all SilcConfigServer* and silc_config_server* to
6814 SilcServerConfig* and silc_server_config*, respectively.
6817 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Associated the ID (client or server ID) to the Authentication
6820 Payload to avoid any possibility of forging. Updated the
6821 protocol specification and the code accordingly.
6823 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * The RSA key length is now save to the RsaKey context in the
6826 key generation process in lib/silccrypt/rsa.c. The key length
6827 is now used to figure out the maximum size of the block allowed
6828 to be encrypted/signed.
6830 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6831 is equivalent to the silc_mp_mp2bin but does not allocate any
6834 * Changed silc_mp_mp2bin API to take length argument. If it is
6835 non-zero then the buffer is allocated that large. If zero, then
6836 the size is approximated using silc_mp_sizeinbase, which however
6839 * Created Global RNG API which is global RNG that application can
6840 initialize. After initializing, any routine anywhere in the
6841 code (including library) can use RNG without allocating a new
6842 RNG object. This was done to allow this sort of use of the
6843 RNG in code that has no chance to allocate RNG object. All
6844 applications currently allocate this and many routines in the
6845 library use this. Affected file lib/silccrypt/silcrng.[ch].
6847 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6848 it to use the Global RNG API.
6850 * Defined Authentication Payload into protocol specification that
6851 is used during SILC session to authenticate entities. It is
6852 used for example by client to authenticate itself to the server
6853 to obtain server operator privileges.
6855 Implemented this payload into the lib/silccore/silcauth.[ch].
6856 Implemented also routines for public key based authentication
6857 as the new protocol specification dictates.
6859 Moved definitions of different authentication methods from
6860 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6862 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6863 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6864 silc_pkcs_verify_with_hash functions into the file
6865 lib/silccrypt/silcpkcs.[ch].
6867 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * The client entry's userinfo pointer must be always valid.
6870 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6871 will fail since it requires the userinfo. Now, the userinfo
6872 is allocated as "" if actual userinfo does not exist. Actually,
6873 it must exist and it is totally Ok to drop client connections
6874 that does not announce the userinfo. However, we will make
6875 this workaround for now.
6877 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6878 to return the remote port by socket.
6880 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6883 SILC_SERVER_PENDING_EXEC and added an new macro
6884 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6885 data or when error occurs while processing the pending command.
6887 Added new argument `destructor' into silc_server_command_pending
6888 and to the SilcServerCommandPending object. This destructor is
6889 now called after calling the pending callback or if error occurs
6890 immediately. If error occurs the actual pending callback won't
6891 be called at all - only the destructor. The destructor may be
6892 NULL if destructor is not needed.
6894 All this applies for client library code as well. Similar
6895 changes were made there as well for the pending commands.
6897 In the client, the application must now allocate the
6898 SilcClientCommandContext with the silc_client_command_alloc
6901 * Added reference counter to the SilcServerCommandContext. Added
6902 function silc_server_command_alloc and silc_server_command_dup
6905 Same type of functions added to the client library for the same
6908 * Removed the cmd_ident from IDListData away since it is now
6909 global for all connections. It is the command identifier used
6910 in command sending and with pending commands. The affected file
6913 * Added reference counter to the SilcSocketConnection objecet to
6914 indicate the usage count of the object. The object won't be
6915 freed untill the reference counter hits zero. Currently only
6916 server uses this, and client ignores it. The client must be
6917 set to use this too later. The affected files are
6918 lib/silccore/silcsockconn.[ch]. Added also the function
6919 silc_socket_dup to increase the reference counter.
6921 This was mainly added because it is possible that the socket
6922 is removed underneath of pending command or other async
6923 operation. Now it won't be free'd and proper DISCONNECTING
6924 flags, etc. can be set to avoid sending data to connection that
6925 is not valid anymore.
6927 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6928 the connection. After that it sets SILC_SET_DISCONNECTED.
6929 It is, however, possible that the socket data is not still freed.
6930 The silc_server_packet_process now checks that data is not
6931 read or written to connection that is DISCONNECTED. The socket
6932 get's freed when the reference counter hits zero.
6934 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Changed the client operation API: channel_message operation's
6937 `sender' is now the client entry of the sender, not the nickname
6938 and the `channel' is the channel entry, not the channel name.
6940 In the private_message operation the `sender' is now also the
6941 client entry of the sender not the nickname.
6943 Affected file is lib/silcclient/ops.h and all applications
6944 using the client operations.
6946 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Moved the calling of ops->connect() from connect_to_server_final
6949 into receive_new_id functin since that is the point when the
6950 client is actually allowed to send traffic to network. The
6951 affected file is lib/silcclient/client.c.
6953 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6956 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6957 (if needs broadcasting) instead of broadcasting the packets one
6958 by one which would make a burst in the network traffic.
6960 * Added `broadcast' argument to the functions in silcd/server.[ch]
6961 silc_server_create_new_channel[_with_id] to indicate whether
6962 to send New Channel packet to primary router.
6964 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Added new function into the silcd/server.[ch] files:
6967 silc_server_create_new_channel_with_id to create new channel with
6968 already existing Channel ID.
6970 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6971 lib/silccore/silcpacket.h. This packet is used t send list of
6972 Set Mode payloads inside one packet. Server uses this to set
6973 the modes for the channels and clients on those channels, that it
6974 announced to the router when it connected to it. The protocol
6975 specification has been updated accordingly.
6977 * The silc_server_new_channel did not handle the packet coming
6978 from normal server as it normally does not send that. However,
6979 when it announces its channels it does send it. Implemented
6980 the support for that.
6982 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6983 into the file lib/silccore/id.h.
6985 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Fixed memory leaks in the functions silc_idlist_del_client,
6988 silc_idlist_del_channel and silc_idlist_del_server in the file
6989 silcd/idlist.c. All of those leaked like a sieve.
6991 * Fixed some small memory leaks in the client's function
6992 silc_client_notify_by_server.
6994 * Added functions into silcd/server.c: silc_server_announce_clients,
6995 silc_server_announce_channels and silc_server_announce_server.
6996 These functions are used by normal and router server to announce
6997 to its primary router about clients, channels and servers (when
6998 router) that we own. This is done after we've connected to the
7001 These functions effectively implements the following packet types:
7002 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7003 and SILC_PACKET_NEW_ID_LIST.
7005 * Added new functions into the silcd/packet_receive.[ch]:
7006 silc_server_new_id_list, silc_server_new_channel_list and
7007 silc_server_new_channel_user_list to handle the incoming
7008 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7010 * Added support of changing Channel ID in the function
7011 silc_server_replace_id. If the server that announces a channel
7012 to the router already exists in the router (with same name but
7013 with different Channel ID), router is responsible to send
7014 Replace ID packet to the server and force the server to change
7015 the Channel ID to the one router has.
7017 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7018 client that the Channel ID has been changed by the router. The
7019 normal server sends this to the client. Client must start using
7020 the new Channel ID as the channel's ID.
7022 Implemented handling of this new type into lib/silcclient/client.c
7023 into the function silc_client_notify_by_server.
7025 * Added new function silc_idlist_replace_channel_id into the files
7026 silcd/idlist.[ch] to replace the Channel ID.
7028 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Call silc_server_command_identify_check always when processing
7031 the IDENTIFY command in silcd/command.c
7033 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7036 send keepalive packets. The packet can be sent by clients,
7037 servers and routers.
7039 Added function silc_socket_set_heartbeat into the file
7040 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7041 If not set, the heartbeat is not performed. The actual
7042 heartbeat is implemented in the low level socket connection
7043 library. However, application is responsible of actually
7046 Added silc_server_send_heartbeat to send the actual heartbeat
7047 packet into silcd/packet_send.[ch]. Server now performs
7048 keepalive with all connections.
7050 * Added silc_task_get_first function into lib/silcutil/silctask.c
7051 to return the timeout task with shortest timeout. There was a bug
7052 in task unregistration that caused problems. TODO has been
7053 updated to include that task system must be rewritten.
7055 * The client library will now resolve the client information when
7056 receiving JOIN notify from server for client that we know but
7057 have incomplete information.
7059 * Rewrote parts of silc_server_remove_from_channels and
7060 silc_server_remove_from_one_channel as they did not remove the
7061 channel in some circumstances even though they should've.
7063 * Encryption problem encountered in server:
7065 The LEAVE command used to send the Channel Key packet to the
7066 router immediately after generating it. However, the code
7067 had earlier sent Remove Channel user packet but not immediately,
7068 ie. it was put to queue. The order of packets in the router
7069 was that Channel Key packet was first and Remove Channel User
7070 packet was second, even though they were encrypted in the
7071 reverse order. For this reason, MAC check failed. Now, this
7072 is fixed by not sending the Channel Key packet immediately but
7073 putting it to queue. However, this is more fundamental problem:
7074 packets that are in queue should actually not be encrypted
7075 because packets that are sent immediately gets encrypted
7076 actually with wrong IV (and thus MAC check fails). So, packets
7077 that are in queue should be encrypted when they are sent to
7078 the wire and not when they put to the queue.
7080 However, the problem is that the current system has not been
7081 designed to work that way. Instead, the packet is encrypted
7082 as soon as possible and left to the queue. The queue is then
7083 just purged into wire. There won't be any fixes for this
7084 any time soon. So, the current semantic for packet sending
7087 o If you send packet to remote host and do not force the send
7088 (the packet will be in queue) then all subsequent packets to the
7089 same remote host must also be put to the queue. Only after the
7090 queue has been purged is it safe again to force the packet
7093 o If you send all packets immediately then it safe to send
7094 any of subsequent packets through the queue, however, after
7095 the first packet is put to queue then any subsequent packets
7096 must also be put to the queue.
7098 Follow these rules and everything works fine.
7100 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Added new function silc_server_remove_clients_by_server to
7103 remove all client entries from ID list when the server connection
7104 is lost. In this case it is also important to invalidate all
7105 client entires as they hold the invalid server entry. This
7106 fixes fatal bug when server has lost connection and will reconnect
7109 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Made some sanity checks to silc_server_daemonise like to check
7112 whether the requested user and group actually exists.
7114 * Added sanity check to SKE's silc_ske_responder_finish to check
7115 that the public and private key actually is valid.
7117 * Invalidate the client's nickname when receiving Replace ID
7118 packet and the Client ID is being replaced. This means that the
7119 server will query the nickname if someone needs it (client)
7122 * Sort the ID Cache in client library when the ID Cache data
7123 has changed (needs sorting).
7125 * Do not allow for SILC client to create several connections to
7126 several servers. The client does not support windows right now
7127 and generating multiple connections causes weird behaviour.
7129 Irssi-silc client does support windows and can handle several
7130 connections without problems, see: www.irssi.org and SILC plugin.
7132 * Fixed some places where client was added to the IDList. The
7133 rule of thumb is following (in order to get everything right):
7134 If the client is directly connected local client then the
7135 `connection' argument must be set and `router' argument must be
7136 NULL to silc_idlist_add_client function. If the client is not
7137 directly connected client then the `router' argument must
7138 bet set and the `connection' argument must be NULL to the
7139 silc_idlist_add_client function.
7141 * The funtion silc_server_packet_send_local_channel actually did
7142 not check whether the client was locally connected or not. It
7143 does that now. Fixed a bug related to LEAVE command.
7145 * Fixed Remove Channel User payload parsing bug in server's
7146 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7148 * The server's silc_server_save_channel_key now checks also the
7149 global ID list for the channel as it might not be in the local
7150 list. Fixed a bug related to LEAVE command.
7152 * Is this the end of the [<unknown>] buglet that has been lurking
7153 around for a long time? A little for loop fix in server's
7154 silc_server_command_whois_parse that is used by both IDENTIFY
7155 and WHOIS command. At least, this was a clear bug and a cause
7156 of one type of [<unknown>] buglet.
7158 * WHOIS and IDENTIFY commands call the function
7159 silc_server_command_[whois/identify]_check function even if
7160 we are not router server.
7162 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * Added --with-gmp configuration option. If set the GMP
7165 is always compiled in the SILC source tree. If not set then
7166 it is checked whether the system has the GMP3 installed. If
7167 it has then the GMP won't be compiled (the system's headers
7168 and library is used), if it doesn't have it then the GMP is
7169 compiled in the SILC source tree.
7171 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7173 * Changed RSA private exponent generation to what PKCS #1
7174 suggests. We try to find the smallest possible d by doing
7175 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7176 not security fix but optimization.
7178 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7180 * Added new config entry [Identity] to fork the server and run
7181 it as specific user and group. A patch from Bostik.
7183 * Imported Dotconf configuration library into lib/dotconf.
7184 This will be used to create the SILC configuration files later.
7185 It will appear in the distsribution after this commit.
7187 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * A big code auditing weekend happening. Auditing code for
7190 obvious mistakes, bugs and errors. Also, removing any code
7193 Removed files for being obsolete:
7195 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7196 inline in the file lib/silcutil/silcbuffer.h)
7198 o lib/silcutil/silcbufutil.c (the header has inline versions)
7200 Changed code to fix possible error conditions:
7202 o The buffer formatting routines now check that the destination
7203 buffer really has enough space to add the data. This applies for
7204 both buffer formatting and unformatting
7205 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7206 unformatting was changed to accomodate following rules:
7207 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7208 sent to the function while XXX_*STRING will not allocate or copy
7209 the data into the buffer. Instead it sets the pointer from the
7210 buffer into the pointer sent as argument (XXX_*STRING used to
7211 require that the pointer must be allocated already). This change
7212 makes this whole thing a bit more consistent and more optimized
7213 (note that the data returned in the unformatting with XXX_*STRING
7214 must not be freed now). The routines return now -1 on error.
7216 o Tried to find all code that use buffer_format and buffer_unformat
7217 and added return value checking to prevent formatting and
7218 especially unformatting errors and possible subsequent fatal
7221 o Changed ske->x and ske->KEY to mallocated pointers in
7222 lib/silcske/silcske.h. Fixed possible data and memory leak.
7224 o Added return value checking to all *_parse* functions. Fixed
7225 many memory leaks as well.
7227 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7228 so that buffer overflows would not happen. All code now also
7229 checks the return value as it can fail.
7231 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Added reconnection support to server if the normal server looses
7234 its connection to the router (for example if router is rebooted).
7235 The server performs normal reconnection strategy implemented
7236 to the server. Affected file silcd/server.c.
7238 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added new packet type SILC_PACKET_SET_MODE that is used to
7241 distribute the information about changed modes (for clients,
7242 channels and clients channel modes) to all routers in the
7243 network. Updated the protocol specification accordingly.
7245 Added functions into silcd/packet_send.c and
7246 silcd/packet_receive.c: silc_server_send_set_mode,
7247 silc_server_set_mode.
7249 Added new files silcmode.[ch] into lib/silccore that implements
7250 the encoding and decoding of Set Mode Payload. Added new type
7251 SilcSetModePayload. Moved the definitions of different modes
7252 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7254 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Oops, a little mistake in server's connection authentication
7257 protocol. The protocol is not ended with FAILURE but with
7258 SUCCESS if the authentication is Ok. :) Affected file is
7261 * Implemented NICK_CHANGE notify handling in server in the file
7262 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7263 the local clients on the channel. After the changing nickname
7264 in router environment snhould work and the [<unknown>] nickname
7265 should appear no more.
7267 The silc_server_replace_id function that receives the Replace ID
7268 payload now sends the NICK_CHANGE notify type also in the file
7269 silcd/packet_receive.c
7271 * Changed WHOIS and IDENTIFY command to support the maximum amount
7272 of arguments defined in protocol specs (3328 arguments). This
7273 fixed a bug that caused problems when there were more than three
7276 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Added extra parameter, command identifier, to the
7279 silc_client_send_command so that explicit command identifier
7282 Changed that ID list routines uses specific command identifier
7283 when sending WHOIS/IDENTIFY requests to the server so that they
7284 can be identified when the reply comes back.
7286 Affected files lib/silcclient/command.[ch],
7287 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7289 * Added `sender' argument to silc_server_packet_send_to_channel
7290 to indicaet the sender who originally sent the packet to us
7291 that we are now re-sending. Ignored if NULL. Affected file
7292 silcd/packet_send.[ch].
7294 * Added some server statistics support in silcd/server_internal.h
7295 SilcServerStatistics structure and around the server code. Also
7296 send some nice statistics information when client is connecting
7299 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Fixed channel ID decoding in server's JOIN command reply in
7302 silcd/command_reply.c
7304 * Fixed braodcasting of replace ID payload to not to send it if
7305 we are standalone server in silcd/packet_receive.c.
7307 * Fixed all channel message sending routines to not to send
7308 packets to clients that has router set, since they are routed
7309 separately in the same function earlier. Affects file
7310 silcd/packet_send.c and all channel packet sending functions.
7312 * In USERS reply, res_argv[i] are not allocated, the table
7313 is allocated. Thus changed that free the table, not its
7316 * In server's whois_check and identify_check if the client is
7317 locally connected do not send any WHOIS commands - they are not
7320 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Fixed some minor bugs in client when sending WHOIS command. The
7323 arguments was in wrong order.
7325 * Removed statis function add_to_channel from server in
7326 silcd/command.c that was previously used with the joining but
7329 * Tested USERS command in router environment successfully with two
7330 routers, two servers and two clients.
7332 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Reorganized the USERS command and command reply in client library
7335 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7336 When the command is given by user we register a pending command
7337 callback that will reprocess the command after the reply has been
7338 received from the server. When reprocessing the packet we then
7339 display the information. Thus, the USERS information is displayed
7340 now in the command callback instead of in the command reply
7341 callback. The processing of the command is same as previously
7342 when server has sent the command reply in the JOINing process.
7344 * Added to USERS command in silcd/command_reply.c to join the client,
7345 we didn't use to know about, to the channel after we've created
7346 a client entry for it. Also, for clienet we did know already still
7347 check whether it is on the channel or not and add it if not.
7349 * Removed silc_server_command_join_notify as the function and its
7352 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7354 * Changed the client's pending command handling to the same as the
7355 server's pending command handling. It is also now possible to
7356 execute command reply functions from other command reply
7357 function as the function callbacks for commands and command
7358 replies are one and same. The pending commands are not static
7359 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7360 in client connection context. Thus, pending commands are server
7361 connection specific as it is convenient.
7363 Changed the function silc_client_command_pending and
7364 silc_client_command_pending_del and added new function
7365 silc_client_command_pending_check. Removed the
7366 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7369 * Added cmd_ident, current command identifier, to the client
7370 connection context in lib/silcclient/client.h to keep track on
7371 command identifiers used in command sending. Client's command reply
7372 function handling now supports the mandatory command identifiers.
7374 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7375 funtions in client to fully support pending command callbacks.
7377 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7378 as one of the arguments to the application in the command reply
7381 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7382 before first releasing SILC but came back. Now it is removed again
7383 and should come back nomore. The FORWARDED flag was used only
7384 by the JOINing procedure by forwarding the command packet to router.
7385 Now, the JOINing procedure has been changed to more generic (due
7386 to various router environment issues) and FORWARDED is not needed
7387 anymore for anything. The protocol specification is yet to be
7390 Now, removed silc_server_packet_forward from server and the flag
7391 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7393 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Renamed NAMES command to USERS command. The NAMES was named that
7396 due to historical reasons. Now it is renamed. Also, rewrote
7397 parts of the USERS command. The nickname list is not sent anymore
7398 by the server. Only Client ID and mode lists are sent in the USERS
7399 command. Changed this also to the protocol specification.
7401 The client now resolves the names and stuff after it receives
7402 the USERS list from the server when joining to the channel.
7404 * WHOIS and IDENTIFY commands has been changed to support multiple
7405 Client ID's per command. One can now search for multiple users
7406 in the network by sending only one WHOIS or IDENTIFY command.
7407 Changed the code and the protocol specifications.
7409 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7410 uses silc_server_command_whois_parse to parse the request. */
7412 * If normal server, do not parse the WHOIS and IDENTIFY requests
7413 before sending it to the router. Saves some time.
7415 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7417 * Fixed JOIN command on client library. Wrong number of arguments
7418 used to crash the client.
7420 * Added silc_server_channel_has_global function to check whether
7421 channel has global users or not.
7423 * Added silc_server_channel_has_local function to check whether channel
7424 has locally connected clients on the channel.
7426 * The silc_server_remove_from_one_channel now checks whether the
7427 channel has global users or not after given client was removed from
7428 the channel. It also checks whether the channel has local clients
7429 on the channel anymore. If it does not have then the channel entry
7430 is removed as it is not needed anymore.
7432 * The silc_server_notify now checks on JOIN notify whether the joining
7433 client is one of locally connected or global. If it is global then
7434 the channel has now global users on the channel and that is marked
7435 to the channel entry. Also, it now saves the global client to
7436 global list who is joining and JOINs it to the channel. This is
7437 for normal server, that is.
7439 Changed silc_server_send_notify_on_channel,
7440 silc_server_packet_relay_to_channel and
7441 silc_server_packet_send_to_channel check if we are normal server
7442 and client has router set (ie. global client) do not send the
7443 message to that client, as it is already routed to our router.
7445 * Implemented LEAVE notify type handling in silc_server_notify
7448 * Tested LEAVE command in router environment successfully. Tested
7449 with two routers, two servers and two clients.
7453 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7455 * Implemented SIGNOFF notify type handling in silc_server_notify
7458 * silc_server_remove_id now removes the client entry from all channels
7459 it has joined and thusly sends SIGNOFF notify type.
7461 * Rewrote the NAMES list generation in server by removing two excess
7462 loops. The lists are created now inside one loop.
7464 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * silc_server_remove_channel_user checks now also global list
7467 for channel and client.
7469 * silc_server_new_channel_user checks now both local and global
7470 list for channel and client. Fixed a bug in client id decoding.
7471 Used to decode wrong buffer.
7473 * silc_server_channel_message checks now both local and global
7474 list for channel entry.
7476 * Tested channel joining (hence JOIN) in router environment
7477 successfully. Tested with two routers, two servers and two
7480 * Tested channel message sending in router environment successfully.
7482 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Added silc_server_save_channel_key into server.[ch] to save the
7485 received channel key in Channel Key payload processing. It is
7486 also used in JOIN command reply handling.
7488 Equivalent function silc_client_save_channel_key added into
7489 client.[ch] into client library.
7491 * Changed JOIN command reply to send information whether the channel
7492 was created or not (is existing already) and the channel key
7493 payload. Changed protocol specs accordingly.
7495 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7496 the request was sent by ID and not by nickname. Crashed on
7499 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7501 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7502 now correctly save the received data.
7504 * silc_server_free_sock_user_data now notifies routers in the
7505 network about entities leaving the network.
7507 At the same time implemented functions silc_server_remove_id
7508 and silc_server_send_remove_id to receive and send REMOVE_ID
7509 packets. The packet is used to notify routers in the network
7510 about leaving entities. The ID removed will become invalid in
7513 * Added function silc_idlist_del_server into server. Removes and
7514 free's server entry from ID list.
7516 * silc_server_private_message function now checks, if we are router,
7517 that the destination ID really is valid ID, naturally.
7519 * In router when NEW_ID packet is received (for new client) the
7520 hash of the Client ID is saved in the ID Cache but the
7521 client->nickname is set to NULL, instead of putting the hash
7524 IDENTIFY command now also checks that client->nickname must be
7525 valid. If it is not if will request the data from the server who
7526 owns the client. Added new function
7527 silc_server_command_identify_check.
7529 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7530 to set the command to already allocated Command Payload.
7532 * Tested private message sending in router environment with two
7533 routers, two servers and two clients. Fixed minor bugs and now
7536 * Fixed segfault from client's NAMES command. Used to crash if
7539 * Forwarded packets must not be routed even if it is not destined
7540 to the receiver. Changed server code comply with this.
7542 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Added `require_reverse_mapping' boolean value to ServerParams
7545 structure. If TRUE (not default) the server will require that
7546 the connecting host has fully qualified domain name.
7548 If the reverse mapping is not required and hostname could not be
7549 found the IP address is used as hostname.
7551 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Implemented version string checking to both client and server.
7554 The check is incomplete currently due to the abnormal version
7555 strings used in development version of SILC.
7557 * Changed all command functions in server to use the new
7560 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Changed char *data to unsigned char *data in ID Cache system to
7563 support binary data as ID Cache data. Changed code to support
7564 binary data in lib/silccore/idcache.c.
7566 * Renamed silc_server_packet_relay_command_reply to
7567 silc_server_command_reply as it is normal packet receiving
7568 function. Rewrote the function to accept command replys for
7569 servers and not only for clients.
7571 * Mark remote router always as registered server if we are connecting
7572 to it. Otherwise, commands sent by the router to us are ignored.
7574 * All ID List find routines now returns the ID Cache Entry pointer
7575 as well if requested.
7577 * WHOIS command works now in router environment, tested with two
7578 routers, two servers and two clients.
7580 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7581 in router environment (as it is almost equivalent to WHOIS) but
7582 hasn't been tested thoroughly. Added new functions:
7584 silc_server_command_identify_parse
7585 silc_server_command_identify_send_reply
7586 silc_server_command_identify_from_client
7587 silc_server_command_identify_from_server
7589 * Disabled route cache adding because adding two different ID's with
7590 same IP replaces the old cache entry thus giving wrong route.
7591 The entry->router->connection is always the fastest route anyway
7592 so route cache may not be needed. Of course, new routes maybe
7593 established after receiving the ID when the entry->router->connection
7594 might not be anymore the most optimal.
7596 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Add route cache for received ID for fast routing.
7600 * Added silc_server_packet_route to route received packet on router
7601 that is not destined to us.
7603 * Renamed silc_server_get_route to silc_server_route_get.
7605 * Added id_string and id_string_len fields into SilcServer to
7606 include encoded ServerID for fast comparing without excess
7607 encoding of the ID's.
7609 * Cleaned up WHOIS command on server side. Added following static
7612 silc_server_command_whois_parse
7613 silc_server_command_whois_check
7614 silc_server_command_whois_send_reply
7615 silc_server_command_whois_from_client
7616 silc_server_command_whois_from_server
7618 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7619 arguments in command replies. All command functions should be
7620 updated to use this macro.
7622 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Minor typo fixes on command reply handling on server.
7626 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Added silc_server_command_add_to_channel internal routine to add
7629 the client to the channel after router has created the channel and
7630 sent command reply to the server.
7632 * Added generic silc_server_send_command to send any command from
7635 * Use static buffer with ID rendering instead of duplicating data.
7637 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Fixed a channel user mode bug when joining to a channel server gave
7640 everybody channel founder rights, oops.
7642 * We mark ourselves as the router of the incoming server connection
7643 if we are router ourselves. This way we can check in some packet
7644 sending functions whether it is locally connected server. For
7645 incoming router connections we put NULL.
7647 * For router sending packets locally means now always sending the
7648 packet cell wide; to local clients and local servers. For normal
7649 server sending packet locally means sending it to only local
7652 * Fixed the JOIN command to really work in router environment. If the
7653 channel is created it is always created by the router. Router is
7654 also responsible of making the initial joining to the channel,
7655 sending JOIN notify to the sending server and distributing
7656 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7657 does not exist server doesn't do anything else but forward the
7658 command to the router which performs everything.
7660 * Added silc_server_send_channel_key function to send the Channel Key
7663 * Added silc_server_create_channel_key to create new channel key. The
7664 channel key is now re-generated everytime someone joins or leaves
7665 a channel, as protocol dictates. Note: channel->key_len is the
7668 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7670 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7671 packet_receive.[ch] to separate packet sending and receiving
7672 routines. The server.[ch] now includes everything else including
7673 actual packet processing (writing and reading data) and other
7676 Renamed silc_server_private_message_send_internal to
7677 silc_server_send_private_message. The routine is still though
7678 used only to relay private messages as server does not send
7679 private messages itself.
7681 Renamed silc_server_new_channel to silc_server_create_new_channel
7682 and added new function sicl_server_new_channel that handles the
7683 incoming New Channel packet. Added also new sending function
7684 silc_server_send_new_channel to send New Channel Payload.
7686 * Added new function silc_server_notify to process incoming notify
7687 packet to the server/router. Server may then relay the notify
7688 to clients if needed.
7690 * Added new function silc_server_new_channel_user to process incoming
7691 New Channel User packet. Router will redistribute the packet and
7692 send JOIN notify to its local clients and locally connected servers
7693 if needed. Normal server will send JOIN notify to its local client
7694 on same channel when received this packet. Added also corresponding
7695 sending function silc_server_send_new_channel_user to sent the
7698 * Added boolean route argument to send_notif_to_channel and
7699 packet_send_to_channel functions to attempt to route the packet
7700 if it is TRUE and send only locally if it is FALSE.
7702 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7704 * silc_server_replace_id now broadcasts the received replace ID
7705 packet if it is not broadcast packet already. The router must
7706 broadcast to inform other routers about changed ID.
7708 * Added backpointer to server's router into SilcServer context in
7709 silcd/server_internal.h.
7711 * Fixed silc_server_packet_broadcast to send correct broadcast
7714 * The channel key is now distributed to the local client as soon
7715 as it is received from the router (in router environment) so that
7716 no other packet may be sent for the channel until client has
7719 * silc_server_remove_channel_user now broadcasts the received
7720 Remove Channel User packet if it is not broadcast packet already.
7721 The router must broadcast to inform other routers about removed
7724 * Added users field into SilcPacketContext that is a reference count
7725 of the context. One can increase the reference count by calling
7726 silc_packet_context_dup which is now changed to just increase the
7727 reference count instead of duplicating the data. The reference
7728 count is decresed by calling silc_packet_context_free that will
7729 free the data after the reference count hits zero.
7731 For now on the packet context and everything allocated into it
7732 (including the raw packet from network) must be freed by calling
7733 the new silc_packet_context_free function. Added also new function
7734 silc_packet_context_alloc that must be used now to allocate the
7735 context. This also means that if a routine is asynchronous from
7736 silc_[client/server]_packet_parse_type the packet context must
7737 be duplicated by calling silc_packet_context_dup. Otherwise it
7738 gets free'd after silc_[client/server]_packet_parse_type returns.
7739 Also, one must remember that if packet is duplicated then its
7740 reference count must be decresed by calling the free function as
7741 many times as it was duplicated.
7743 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7744 from both client and server.
7746 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Made joining to a channel working in router environment.
7750 * Cleaned up JOIN command on server side and create function
7751 silc_server_command_join_channel internal routine to make the
7754 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7756 * Changed silc_command_pending list to SilcDList. Also, added
7757 `ident' field to SilcServerCommandPending structure to identify
7758 the reply and to call correct callback.
7760 Added silc_server_command_pending_check function to replace the
7761 corresnponding macro. The silc_command_pending list is not
7764 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7765 to set identifier to previously allocated Command Payload. It
7766 is used to set identifier for command when resending Command
7769 * Added silc_command_payload_encode_payload to encode Command
7770 Payload buffer from SilcCommandPayload structure.
7772 * Added silc_argument_payload_encode_payload to encode Argument
7773 payload buffer from SilcArgumentPayload structure.
7775 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7777 * Changed WHOIS command to support router connection on server side.
7778 The whois request is always sent to router unless the server is
7779 standalone server. After server has received the reply from the
7780 router will it send the reply to the client.
7782 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7783 broadcast received broadcast packet. The function is used only
7784 by router. The broadcast packet is always sent to the router's
7787 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7788 render given ID to printable string, for log files for example.
7790 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Made basic router to router connections working. At least they
7793 can now connect to each other but nothing really works the way
7794 they are supposed - yet.
7796 * Added new initiator token to RouterConnection configuration
7797 file in silcd/serverconfig.[ch]. It is used to tell whether we
7798 are the initiator to the remote router or whether we'll expect
7799 the other end to connect.
7801 * Moved registering of listener task to silc_server_init, hence
7802 the server starts listenning as soon as it is run, even if it
7803 does not have connections to other routers. Let's see how well
7806 * Changed default connection retry timeouts for more suitable in
7809 * Removed cipher and such arguments from silc_idlist_add_client
7810 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7811 Added new function silc_idlist_add_data to add the keys and stuff
7814 * Added SilcIDListData structure and added it to SilcClientEntry
7815 and SilcServerEntry as their first field in the structure. This
7816 way we can explicitly cast the ID entries to the SilcIDListData
7817 structure and get common data for the entries. In past, we had
7818 to first check what type of connection it is and then cast it to
7819 correct ID entry type. Now, we can directly cast the opaque
7820 pointer to the SilcIDListData (no matter what ID entry it actually
7821 is) and get the data needed.
7823 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7826 in some circumstances even if threre were timeout tasks, though not
7827 IO tasks, but tasks anyway. Now fixed.
7829 * Defined SilcServerConnection structure to hold connection specific
7830 stuff about directly connected servers and routers. The definition
7831 is currently in silcd/server_internal.h. I thought about having
7832 a bit more important role fro this struct but for now it is used
7833 only when connecting to other server (or router actually).
7835 * Added connecting retry support in server when connecting to
7836 router(s). The retry feature implement exponential backoff
7837 algorithm. Also, added SilcServerParams structure to hold default
7838 parameters for server. For now, it include these retry settings
7839 and are hard coded. After server is moded to be as Silc Server
7840 Library this structure will be more important.
7842 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7844 * Changed client librarys channel->clients table to SilcList and
7845 changed code accordingly.
7847 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Changed client's channel table to SilcList and changed code
7850 accordingly. Also changed SilcChannelClientEntry to include back-
7851 pointer to the channel so that client entry can use that structure
7852 as list as well and we have fast cross-reference to the channel.
7853 This change dramatically decreased the complexity of channel
7854 handling with client entry and vice versa (removed one extra
7855 loop when searching for channel entry from many functions).
7857 * Changed server->sim from table to SilcDList and changed code
7860 * NAMES command can now be used from user interface. It will show
7861 the user list on the channel, neatly.
7863 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7864 Code now saves realname of the user if it becomes available.
7866 * Renamed configure.in to configure.in.pre and made ./prepare
7867 script to automatically add correct version string to
7868 configure.in which it creates from configure.in.pre.
7870 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7872 * NAMES command reply now shows users mode with the nickname when
7875 * Moved silc_client_ch[u]mode[_char] functions from
7876 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7877 place sucks, they are utility functions and should be in some
7880 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7882 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7885 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7889 * Added TRQ (efficient deque and list library) into lib/trq. This is
7890 a very good list library that is currently used in the SILC. Defined
7891 SilcList API over the library because I didn't like the API very
7892 much. See lib/trq/silclist.h for the API and examples of how to
7893 use the API. Fixed various places in the code to use the new
7894 SilcList API. The SilcList is meant for lists that has a structure
7895 already defined as a list. It is not suitable to add just some
7896 context to the list (in TRQ, the context is the list actually).
7898 So, I defined SilcDList that can be used for the purpose where
7899 predefined list structure does not exit. This can be used as
7900 such list. Now some context just can be added to the SilcDList.
7901 Currently this list is not used in the SILC just yet, though there
7902 are a lot places where this can replace dynamically allocated
7903 tables and I will fix these places, later, to use SilcDList.
7904 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7905 and use TRQ internally).
7907 Also fixed some annoying warning messages that the original TRQ
7908 code generated. Also minor changes to TRQ's Makefile.in.
7910 * Added support for querying by Client ID to both WHOIS and
7911 IDENTIFY commands into server, as required by the protocol.
7913 * Removed method function pointers from SilcBuffer structure. They
7914 weren't used to anything and just increased the context size for
7915 no good reason. This change also made silc_buffer_alloc and
7916 silc_buffer_free functions inline functions.
7918 * Disabled command flooding detection support until it's fixed so
7919 that it accepts commands in but does not execute them more than once
7922 * Added silc_net_localhost(), to return local hostname, into
7923 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7924 that must be initialized before calling silc_client_init.
7926 * Added new function: silc_server_send_notify_on_channels to send
7927 notify messages to all channels client has joined. It is assured
7928 that the message is sent only once per client.
7930 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7931 lib/silcutil/silcutil.[ch] as silc_format function. The new
7932 function is generic and is used by server as well, not only by
7933 the logging routines.
7935 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7936 the provided version string was not acceptable. Added new function:
7937 silc_ske_check_version into lib/silcske/silcske.h. The function
7938 must be implemented by the application (client or server) and it
7939 does not reside in the SKE library. The function checks the version
7940 string remote end sent.
7942 * Added back pointers (to opaque context and to SilcSocketConnection)
7943 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7945 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7946 duplicate packet context structure.
7948 * Changed `notify' client operation to send same arguments as client
7949 receives from server except for ID's. ID's are mapped to correct
7950 ID entry and that is returned. Also, if channel entry is not sent
7951 by server but the notify is for channel the channel entry is sent
7952 to application (otherwise application doesn't know that it is for
7953 channel (library gets it from packet's Destination ID)).
7955 * Added silc_client_remove_from_channels into client library to
7956 remove a client from all channels it has joined to. Used when
7957 received SIGNOFF notify from server. Added also new function
7958 silc_client_replace_from_channels to replace old ID entry with
7959 new ID entry on all channels. Used when received NICK_CHANGE
7962 * Fixed ID Cache list handling in silc_idlist_get_client in
7963 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7964 to get (or query) client by ID.
7966 * Updated TODO list.
7968 * Added connection authentication status message defined by the
7969 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7970 support for these into the code in client and server side.
7972 * Added generic function silc_client_send_command to send any command
7973 with variable argument list. Application should use this function
7974 to send commands if the command functions provided by the library
7975 does not suite for the application's user interface needs.
7977 * Added new `failure' client operation. Application is notified about
7978 received failure packet if client is executing a protocol. In this
7979 case the protocol's execution has failed.
7981 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7982 is required by the protocol.
7984 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7985 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7988 * Added status flag to SilcSKE object to indicate realtime status
7989 of the SKE protocol.
7991 * Application receives now exactly same command reply arguments as
7992 the library receives from server. However, if ID is received the
7993 corresponding ID entry is returned to the application (eg. Client
7994 ID is mapped to correct SilcClientEntry entry and that is returned).
7995 Changed command_reply client operation due to this change.
7997 * Changed all ID's in commands and in command replys as ID Payloads.
7998 Change affected both client and server side codes.
8000 All ID's sent in SILC network (with execption of ID's in SILC
8001 Packet header) are sent in ID Payload to support variable length
8004 * Server now notifies nick changes and notifies all clients on
8005 the channels about the new nickname (about the new Client ID,
8008 * Implemented CMODE command to change channel modes. Supports all
8009 channel modes defined by the protocol specs except ban and invite
8010 lists. (Also, private channel key mode is supported but support for
8011 setting private channel key in client is missing, thus, this mode
8012 has no effect on client side (except that server requires that the
8013 client uses private channel key and normal channel traffic does not
8016 Also, invite mode works per se, but INVITE command does not work
8017 yet correctly, so you can set channel as invite only channel but
8018 inviting clients to the channel does not work (it is yet to be
8019 thought what's the best way to do it).
8021 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8022 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8023 Implemented CUMODE command to change user's mode on the channel.
8024 Supports all modes defined by the protocol specs.
8026 * Added NAMES command reply to return users modes on the channel.
8028 * Removed unnecessary and slow ciphers from lib/silccrypt.
8030 * Set SO_KEEPALIVE option to connection sockets by default.
8032 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8034 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8035 redefined the Notify Payload into protocol specs.
8037 * Added silc_id_payload_parse_id to get ID directly from raw
8040 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8042 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8043 accept searching by Client ID as well.
8045 * Added support for LEAVE and SIGNOFF notify types in client library.
8047 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8048 to parse ID Payload from raw data.
8050 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Added flags parameter into silc_ske_assemble_security_properties
8053 function in lib/silcske/silcske.[ch].
8055 * Changed notify client operation to fit better for notify messages
8056 sent by server. The notify payload received from server is now
8057 passed to the application (after parsing it to SilcNotifyPayload).
8058 It is application's responsibility to retrieve the arguments
8059 from the payload and show the message the way it wants. The message
8060 sent by server is implementation specific.
8062 * Changed public keys to comply with the protocol specification.
8063 Old public keys are not supported anymore and are not compatible.
8065 * Removed nickname from Channel Payload as the latest draft removed
8066 it. The client must resolve the nickname from the NAMES command
8067 reply received when it joined the channel.
8069 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8071 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Fixed some errors in protocol specification drafts.
8075 * Created lib/silccore/silcnotify.c to implement Notify Payload
8076 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8077 generic payloads described by protocol specifications. The file
8078 includes implementations for ID Payload and Argument Payload.
8080 * Changed Command Payload implementation to use the new Argument
8081 Payload. Changed command_xxxx_payload to command_payload_xxxx
8082 to comply with SILC coding conventions.
8084 * Added suppport for Argument Payload handling in Notify Payload
8085 implementation as protocol requires it. Added the new support
8086 into server and client lib as well.
8088 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8090 * Added support for multiple nicknames on same channel. [n] is
8091 added locally to the nickname if there are more than one same
8092 nicknames on the channel.
8094 * Server now sends all nicknames that matched WHOIS request.
8095 Client also shows the list received from server.
8097 * Added TOPIC command to client side. User can now set and show
8098 current topic on channel.
8100 * Added MOTD command to client and server. Also, server sends the
8101 motd when client connects to the server.
8103 * Changed version strings to comply ISO 8601.
8105 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8107 * Fixed protocol error handling in client library. It should now
8108 cope even if the SKE fails for some reason.
8110 * Made new protocol specification drafts for submitting to IETF.
8112 * Implemented TOPIC command to server in silcd/command.c.
8114 * Added two new notify types into lib/silccore/silcnotify.h:
8115 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8116 notify nickname change and topic setting/change on a channel.
8118 * API change of command_reply operation in client library. The
8119 application gets now the status type received from server as well.
8121 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8125 * Cras fixed and optimized the packet handling even further and
8126 it should work now. Minor change to the prototype of function
8127 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8129 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * Added new function into lib/silcutil/silcschedule.[ch]:
8132 silc_schedule_with_fd to select() a specified fd. The function
8133 returns after timeout expires or data arrives or goes. The
8134 function is used by packet routines to wait that all data is
8135 received from network.
8137 * Fixed data reading from network in lib/silccore/silcpacket.c.
8138 The code now assures that all data is read from the fd and then
8139 continues packet processing. This was a bug fix since the code
8140 used to drop some data in some circumstances.
8142 * Added new function into lib/silcclient/client.[ch]:
8143 silc_client_start_key_exchange to start key exchange after
8144 connection has been established to server. The code internally
8145 now uses this funtion but its main purpose was to provide it
8146 for applications that perform their own connecting. After
8147 application has created a connection it merely calls this
8148 function to start the key exchange between client and server.
8149 The library takes care of everything else after that.
8151 Updated also lib/silcclient/README to explain the usage of
8154 * Do not send to application information that connection has
8155 been established. Application gets notified it by connect
8158 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * Applied cras's patch to add silc_schedule_one function. The
8161 function runs scheduler once and returns.
8163 * Fixed the scheduler after cras messed it up. The timeout
8164 handling works now as it's supposed to work.
8166 * Added into lib/silccore/ silcnotify.h to include notify
8167 message types support. Changed silc_server_send_notify*
8168 functions, in server.[ch], to support those new notify types.
8169 Added the support for the notify types into client library,
8170 as well. Added new notify client operation into ops.h in
8173 * Changed silc_server_packet_send_to_channel to send normal
8174 packets instead of just channel message packets. The function
8175 is now used to send the notify packets to channels. It is not
8176 used to send channel message packets anymore, as server never
8179 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8180 va_arg()s as it seems to require it nowadays. I guess, if SILC
8181 is compiled with older va_arg() the new code should work anyway.
8183 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Splitted core library. Core library (lib/silccore) includes
8186 now only SILC protocol specific core (and common) components.
8187 Created new utility library (lib/silcutil) that includes more
8188 generic purpose stuff. The stuff for util library was taken
8189 from the old core library. This was minor and easy split.
8191 * Created SILC Client Library (lib/silcclient) that includes
8192 implementation of the SILC client without user interface. This
8193 was major move from silc/ directory. The code has been changed
8194 so that it is transparent towards the user interface. The
8195 silc/ directory includes now the same user interface as before
8196 and it uses the new client library. Read lib/silcclient/README.
8197 Basicly, the client library performs everything else related
8198 to SILC except user interface handling. Also, configuration
8199 files are considered to be part of user interface and library
8200 does not handle them.
8202 This change also changed a lot of structures, function naming etc.
8203 Most important change was that SilcClientWindow object was
8204 renamed to SilcClientConnection in the client library. Created
8205 also new file lib/silcclient/ops.h. Also added new files
8206 silc/local_command.[ch] and silc/client_ops.[ch].
8208 All these changes were made to make it easier for user interface
8209 designers to create what ever user interface for the SILC client
8212 It is also expected that the server will be moved to lib
8213 directory as well and SILC Server Library will be created;
8214 sometimes in the future.
8216 * Removed Local commands from lib/silccore/silccommand.h as
8217 they are application specific and new client library does not
8218 handle any of those anymore.
8220 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8221 old client implementation in silc/.
8223 * Added support for callback functions in SILC_LOG_* macros.
8224 Application can now set its own callbacks that will be called
8225 instead of using the default functions that will always print
8226 the debug messages to stderr (or stdout). Also, debugging can
8227 now be disabled by setting silc_debug to FALSE and re-enabled by
8228 setting it to TRUE. Note, that logging will still work even
8229 if debugging is disabled.
8231 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8232 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8233 silc_log_reset_debug_callbacks.
8235 * To enable debugging in silc client one must give now -d
8236 option on command line.
8238 * Changed silc_schedule_init to automatically allocate task queues
8239 if they are not allocated before calling it.
8241 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Added GMP 3.1 into math library.
8245 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8247 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8248 a channel in SILC network. The packet is used by servers and
8249 routers to notify other routers that user has left a channel.
8250 This little feature was missing until now. Added the feature
8251 to protocol specification as well.
8253 Added functions: silc_server_send_remove_channel_user and
8254 silc_server_remove_channel_user into server.[ch].
8256 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8257 lib/silccore/silcpacket.h. However, they are not implemented
8260 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Fixed joining to a channel and sending channel messages
8263 between server and router. The channel message sending should
8264 now work inside a cell.
8266 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8268 * Fixed the private message sending between server and router.
8269 The private message sending should now work inside a cell.
8271 * Added silc_server_replace_id into server.[ch] to replace
8272 existing ID in the SILC network.
8274 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8275 and silc_idlist_replace_server_id into idlist.[ch] in server.
8277 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8279 * Fixed the server to server connections. Server can again now
8280 connect to router. Router to router connections probably does
8283 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8285 * Added dynamic protocol registering support. Now protocols can
8286 registered and unregistered on the fly. Patch by cras.
8288 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8290 * Added lib/contrib directory to hold routines that some platforms
8291 don't have but are needed by SILC.
8293 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8294 into lin/contrib to provide getopt() and getopt_long() for
8295 those who don't have it.
8297 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8299 * Added AWAY command to client. When away message is set and
8300 client receives a private message packet the client automatically
8301 replies to the sender with the away message.
8303 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8304 bug seemed to be the cause of recent problems when compiling
8307 * Added version detection support to SKE protocol specification
8308 and added the new changes to the SKE implementation as well.
8309 There were other minor changes in the SKE protocol as well.
8311 Many changes in lib/silcske/silcske.[ch] and in
8312 lib/silcske/payload.[ch].
8314 * Added ^U functionality, clear input line. Patch from cras.
8316 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8318 * Mainly small bugfixes on core library. Fixed some debugging
8319 logging and buffer overflow in silclog.c.
8321 * Updated config.sub and config.guess on the distribution tree.
8323 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8325 * Added command lagging support in server. Client may execute
8326 commands now only once in two seconds.
8328 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Optimized packet reception. MAC computation and checking is now
8331 also more optimized. A lot previously duplicated code is now
8332 used as generic by both client and server.
8334 * Fixed key pair generation in clientutil.c
8336 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Added into lib/silccore/silcbufutil.[ch] new function;
8339 silc_buffer_realloc.
8341 * Moved generic packet sending/encryption functions to
8342 lib/silccore/silcpacket.[ch] from client and server. Some
8343 rewriting of the functions.
8345 * Moved all generic packet reception/decryption functions to
8346 lib/silccore/silcpacket.[ch] from client and server. The
8347 packet processing is now much cleaner in both client and server.
8348 These were major changes in both client and server.
8350 * Created many common functions in server to do packet sending.
8351 Previously code were duplicated a lot, this has been removed
8354 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8356 * Rewrote major parts of the ID cache system. Don't know
8357 whether it is better now or not but at least the API is more
8360 * Major rewrite on ID cache stuff on client because of the ID
8361 cache API changes. Added idlist.c to client.
8363 * Also major rewrite on ID cache stuff on server as well.
8364 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8365 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8366 in hand, instead they are all put into the ID cache system now.
8367 All server_idlist_* routines uses ID cache now instead of
8368 traversing its own lists (those lists does not exist anymore).
8369 SilcIDList though still exists. Also, SilcXXXEntry's are
8372 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8374 * Finally made the SKE implementation compliant to the protocol
8375 specification. All mp integers are now binary encoded as
8376 opposed being HEX encoded.
8378 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8381 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8382 functions: silc_[encode/decode]_pem. Also added function
8383 silc_encode_pem_file to PEM encode with newlines ('\n') for
8386 * SILC public keys are now encoded either PEM or binary. Same
8387 option is for private keys as well. By default private keys
8388 are binary encoded and public keys PEM encoded. Silly HEX
8389 encoding were removed.
8391 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8392 function to create fingerprints.
8394 * Fixed a bug in SHA1; does not change the original data anymore.
8396 * Partly implemented INFO command on client and server side.
8397 Fixed CLEAR command. Changes to SERVER command; show current
8398 server(s) when giving command without arguments. Added
8399 VERSION command to client.
8401 * Added check to server that unregistered connections cannot
8402 execute commands (unless it is specificly allowed).
8404 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * Fixed screen refresh.
8408 * Fixed channel joining bug from client. On some circumstances
8409 client tried to join to a channel it had already joined.
8411 * Added public key verification process into client's protocol.c.
8412 The client now verifies the public key from user and saves
8413 it into ~./silc/serverkeys/ directory.
8415 Added into: clientutil.[ch]: silc_client_verify_server_key.
8417 * Changed SKE protocol's silc_ske_initiator_finish function
8418 to accept callback function that verifies the received public
8419 key. Removed old silc_ske_verify_public_key function.
8421 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8423 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8424 silc_pkcs_private_key[_data]_set.
8426 * Made the password and public authentication more cleaner in
8427 server's protocol.c.
8429 * Removed historic and obsolete protocol `channel_auth' from
8430 both client and server.
8432 * Removed wrong way of sending command status messages from
8433 server to client in server's command.c. The old way violated
8434 protocol specification.
8436 Changes to silccore/silccommand.[ch]: removed
8437 silc_command_encode_status_payload -> not needed anymore,
8438 changed silc_command_encode_payload_va to accept extra
8439 argument on variable argument list. The argument type must
8440 now be provided to the function. Also, added new function:
8441 silc_command_encode_reply_payload_va which is same as
8442 normal command_encode_payload_va except command status type
8443 is provided as extra argument.
8445 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8447 * Added ~./silc directory handling. The directory includes the
8448 public and private keys for the client.
8450 Added silc_client_check_silc_dir, silc_client_create_identifier
8451 and silc_client_load_keys.
8453 * Implemented SILC protocol compliant public key. Added public
8454 and private key saving to and loading from files.
8456 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8457 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8458 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8459 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8460 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8462 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8463 silc_pkcs_load_[public/private]_key.
8465 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8467 * Added silc_server_get_route (route.[ch]) to get connection
8468 data for the fastest route for given ID.
8470 * Implemented INVITE command on client and server. The command
8471 were re-defined in the SILC Protocol Specification and the
8472 implementation now complies with the specification.
8474 * Implemented PING command on client and server.
8476 * Implemented NAMES command on client and server. The server side
8477 supports currently only normal server not router server yet.
8478 Some changes to NAMES definition in SILC protocol specification.
8480 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8482 * Implemented LEAVE command on client and server.
8484 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8485 again. This change was made to the protocol as well. Server
8486 should not violate the protocol specification anymore.
8488 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8490 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8491 was tested. SOCKS4 was not but should work anyway.
