530 lib/silcclient/protocol.c, silcd/protocol.c,
531 silcd/serverconfig.c, and lib/silccore/silcauth.c.
533 * Changed the silc_client_close_connection interface to not
534 need the SilcSocketConnection which should not be visible
535 to application. Affected files are lib/silcclient/client.c
536 and lib/silcclient/silcclient.h.
538 * Rewrote the text for Private Message Key Payload in the
539 protocol specification. Protocol TODO #11.
541 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
543 * Upgraded the protocol version to 1.1, updated protocol specs
546 * Added the nickname as new argument to NICK_CHANGE notify and
547 added it to protocol specs and implemented it to client and
548 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
549 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
550 lib/silcclient/client_notify.c.
552 * Added the killer's client ID to the KILLED notify and added

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

601 Added new options m and M to CMODE command in Irssi SILC
602 client to set these modes.
604 * Deprecated all administrative commands from SILC protocol
605 since they are highly implementation specific commands.
606 Updated protocol specs. Moved the old commands in
607 implementations to private range of command types. Affected
608 files are silcd/command.c, lib/silcclient/command.c and
609 lib/silcclient/command_reply.c. Protocol TODO #8.
611 * Fixed a bug in server where sending unknown command crashes
612 the server. Affected file silcd/command.c.
614 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
616 * Added SILC_PROTOCOLVERSION macro to check protocol version
617 of a socket connection. The affected file is
618 lib/silcutil/silcsockconn.h.
620 * Added better error logging in rekey protocol. Affected file
623 * Do not check public key types in SKE during rekey. Affected
624 file lib/silcske/payload.c.
626 * Fixed the rekey protocol with PFS, which was totally broken.
627 Affected file silcd/protocol.c.
629 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
631 * Some client implementations quit network by doing first LEAVE
632 and then immediately SIGNOFF (like Bombyx). We now do check
633 after a short time after LEAVE notify and check whether the
634 client is still valid after LEAVE, and if not we remove it from
635 cache. Affected file is lib/silcclient/client_notify.c.
637 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
639 * Merged version 1.1.4 of zlib. Even if it not currently in use,
640 it's good not to have security holes here.
642 * Fixed a negative refcount situtuation for the config context.
643 Affected file is silcd/serverconfig.c.
645 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
647 * ROBOdoc documented lib/silcutil/silcutil.h.
649 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
651 * Optimized even more the SilcPacketContext structure. Now
652 totally saved 16 bytes of memory per context after optimization.
653 Affected files are lib/silccore/silcpacket.[ch].
655 * Made strict checks for valid SILC IDs. Affected file is
656 lib/silccore/silcid.c.
658 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Changed the object argument for silc_cipher_register,
661 silc_hash_register, silc_hmac_register and silc_pkcs_register
662 to const. Affected files are lib/silccrypt/silccipher.[ch],
663 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
665 * Changed the silc_get_username and silc_get_real_name to
666 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
668 * Fixed the Irssi SILC Client to use the silc_get_username and
669 silc_get_real_name insted of glib routines since the glib
670 routines only corrupt stack. Fixes the Irssi SILC to work in
671 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
673 * Fixed the Irssi to not use g_get_home_dir since it crashes
674 or returns garbage on cygwin and corrupts stack. Added function
675 get_home_dir to Irssi routines. Affected files are
676 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
678 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Made some structure optimizations. SFTP memory FS MemFSEntry
681 entry structure. Optimized SilcTask structure. Optimized
682 SilcPacketContext structure.
684 Affected files lib/silcsftp/sftp_fs_memory.c,
685 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
687 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
689 * And yet again reverted back the config thing since Johnny
690 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
693 * Fixed memory leaks from config object. Affected files are
694 silcd/serverconfig.[ch].
696 * Added support for adding new connections to the server in rehash.
697 After rehash they take effect.
699 Added support for changing the maximum allowed connections in
700 rehash. The number can grow but going smaller is not supported.
702 Added function silc_server_num_sockets_by_remote to the
703 silcd/server_util.[ch].
705 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
707 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
709 * Added preliminary checking during config parsing for a valid
710 public/private key and removed further checks in the code.
711 Affected files are silcd/serverconfig.[ch], server.c.
713 * Moved functions silc_server_drop() and silc_server_daemonise()
714 from server.c to silcd.c since they are stricly related to
715 the application activity.
717 * Reverted a small part of the automatic ref/unref since
718 it caused a double unref in some situations. Affected
719 files are silcd/silcd.[ch], server.c, serverconfig.c.
721 * Added some .cvsignore files in the lib directory.
723 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Fixed silc_net_gethostbyaddr to correctly resolve by
726 address. Affected file lib/silcutil/silcnet.c.
728 * Fixed the notify relaying to client. The HMAC to be used
729 with relayed packets ws wrong and caused decryption failure
730 at the client end. Affected file is silcd/packet_receive.c.
732 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Created new branch silc_protocol_1_0_branch.
736 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
738 * Changed the silc_server_config_* routines to be SilcServer
739 independent. They are now officially application specific code
740 and not part of generic server implementation. Affected files
741 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
743 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added automatic referencing of config context in the
746 silc_server_config_alloc, and automatic unreferencing in the
747 silc_server_config_destroy. Affected files are
748 silcd/serverconfig.[ch], silcd/silcd.c.
750 * Fixed the silc_log_quick handling in the logging routines.
751 It didn't log quickly when it was TRUE. Affected file is
752 lib/silcutil/silclog.c. Also the flush delay was set even
753 if it was 0 in config file. Affected file is
754 silcd/serverconfig.c.
756 * Added support for changing key pair of the server in rehash.
757 Affected file silcd/server.c.
759 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
761 * Fixed the TOPIC_SET notify to not cras. It changed the topic
762 too early, before getting the channel entry. Affected file
763 is silcd/packet_receive.c.
765 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
767 * Added functions silc_server_config_[ref/unref], these are used
768 to prevent that the config object is destroyed.
770 No longer directly affect global variables silc_log_quick and
771 silc_log_delay, they are first cached inside the config object
772 and then applied with silc_server_config_setlogfiles().
774 silc_server_config_set_defaults() is now internal to
775 serverconfig.c, there are no reasons to show this internal stuff
778 Affected files are silcd/serverconfig.[ch].
780 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
781 fprintf's to stderr, since some code may be executed again after
782 the server went into the background. Affected files are
785 * Added rehash support. Added function silc_server_rehash() that
786 will perform all the basic tasks of the rehashing procedure.
788 * Added command line option `-x, --hexdump'. This will enable the
789 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
790 The option `--hexdump' implies `--debug'.
792 * Fixed a bad bug in the logging APIs (silcutil library) where
793 the application would crash after calling silc_log_reset_all().
795 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Fixed the KICKED notify handling in client library to
798 correctly remove the channel and all entries from the
799 channel when I was kicked. This bug crashed the client.
801 Fixed yet another but in KICKED notify handling to remove
802 the kicked client correctly from the channel.
804 Affected file is lib/silcclient/client_notify.c.
806 * Fixed a minor bug in looking up correct client entry
807 in KICKED notify in server. Affected file is
808 silcd/packet_receive.c.
810 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
811 sources correctly to distribution. Fixes --with-gmp option.
813 * Removed the manual rehashing from ID Cache, and changed it
814 to use the SILC Hash Table's auto rehash feature. Affected
815 file is lib/silccore/silcidcache.c.
817 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed a bug in the silc_client_nickname_format function that
820 handles the multiple same nickname formatting. Two clients
821 with same nickname caused problems after the first one left
822 and rejoined. It didn't format the nickname correctly.
823 Affected file is lib/silcclient/idlist.c.
825 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Don't change the topic if olod topic is same as new one.
828 Affected file is silcd/packet_receive.c.
830 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
832 * Added cross-reference support to the SILC Documentation
833 generator. All types across all HTML files are now cross-
834 referenced. Affected files util/robodoc/generator.c and
835 scripts/silcdoc/silcdoc.
837 * Added file lib/silcutil/silctypes.h to include all the
838 arithmetic type definitions and some macros. Removed
839 includes/bitmove.h and moved macros to silctypes.h.
841 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
845 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * Added `type' argument to silc_id_payload_parse_id function which
848 now returns the type of the ID to the sent pointer. Affected
849 file is lib/silccore/silcid.[ch].
851 * Added check for CMODE_CHANGE notify type that mode change is
852 allowed by the sender. Affected file silcd/packet_receive.c.
854 * Added check for CUMODE_CHANGE notify type that mode change is
855 allowed by the sender. Affected file silcd/packet_receive.c.
856 Added the ID type as CUMODE_CHANGE notify type as argument
857 to the `notify' client operation. Affected files are
858 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
860 * Added function silc_client_add_server to the client library.
861 Added support for resolving also channel and server info when
862 received unknown entity in notify packet. Affected files are
863 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
865 * Added function silc_command_get_status to return the command
866 status from the command reply's argument payload. Affected files
867 are lib/silccore/silccommand.[ch].
869 * Added check for KICKED notify type that the kicking is
870 allowed by the client. Affected file silcd/packet_receive.c.
872 * Created function silc_get_input which can be used to get input
873 (echo on or off) from user on command line. Affected files are
874 lib/silcutil/silcutil.[ch].
876 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Optimized silc_server_packet_relay_to_channel function.
879 Added new function silc_channel_message_payload_encrypt which
880 can be called directly if channel message payload needs to
881 be encrypted and is already encoded (no need to call _encode
882 function). Packet relaying is now done by router without any
883 extra memory allocations. Affected files are
884 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
887 * Fixed the INVITE notify handling. It took wrong arguments
888 as invite list and invite delete. Affected file is
889 silcd/packet_receive.c.
891 * Added check for TOPIC_SET notify type that the topic change is
892 allowed by the client. Affected file silcd/packet_receive.c.
894 * Added check for INVITE notify type that inviting is allowed by
895 the client. Affected file silcd/packet_receive.c.

898 SilcChannelClientEntry as well. Moved the function
899 silc_server_check_cmode_rights to server_util.[ch].
900 Affected files are silcd/server_util.[ch], silcd/command.c.
902 * Added function silc_server_check_umode_rights to check whether
903 changing client's user mode is allowed. Added check for
904 UMODE_CHANGE notify type that the umode change is allowed
905 by the client. Affected files are silcd/server_util.[ch],
906 silcd/packet_receive.c and silcd/command.c.
908 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
911 ID length. It ignored that ID can be IPv6 based as well.
912 Affected file lib/silccore/silcpacket.h.
914 * Fixed the silc_id_id2str and silc_id_str2id to take the
915 IPv6 address offset's into consideration. Affecte file is
916 lib/silccore/silcid.c.
918 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Fixed the internal Unix scheduler functions to check for
921 NULL context they may receive. The affected file is
922 lib/silcutil/unix/silcunixschedule.c.
924 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
926 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
927 can specify different directory with --home command line
928 parameter. Affected files irssi/src/silc/core/client_ops.c,
931 * SILC-specific commands aren't now executed if the active server
932 isn't of SILC-type, so there won't be problems with having
933 IRC and SILC protocol support in same client. Affected files
934 irssi/src/silc/core/silc-channels.c, silc-servers.c,
937 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Improved the signal support in SILC Schedule. Added new
940 function silc_schedule_signal_call which is used by application
941 to mark a signal to be called. It is now safe to perform
942 any kind of tasks in signal callbacks since it is guaranteed
943 that the application specified signal callback is called
944 after the signal is over. Affected files are
945 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
947 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
949 * Added `name' field to SilcChannelPrivateKey to represent
950 application given name for the key. Moved also the context from
951 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
952 Added the `name' argument also to the function
953 silc_client_add_channel_private_key.
955 Added function silc_client_current_channel_private_key to set the
956 current channel private key in use.
958 Added "change" command to KEY command which can be used to change
959 the current channel private key. Bound the command also to
962 Also affected files lib/silcclient/client_channel.c,
963 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
965 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
967 * Added silc_rng_get_byte_fast function in to the
968 lib/silccrypt/silcrng.[ch].
970 * Changed the interface of silc_packet_assemble and the
971 silc_packet_send_prepare. If silc_packet_assmble is now
972 called the application does not call silc_packet_send_prepare
973 because the library will call it automatically. These
974 interfaces now also return a reference to the outgoing buffer
975 which includes the assembled packet, which the application can
976 use to encrypt the packet.
978 Affected files are lib/silccore/silcpacket.[ch],
979 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
980 silcd/packet_send.c, server_backup.c and packet_receive.c.
982 * Fixed a packet sending bug on very high load, where outgoing
983 packet queue wasn't handled correctly and packets got corrupted.
984 Affected files are lib/silcutil/*/silc*sockconn.c,
985 lib/silcclient/client.c and silcd/server.c.
987 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
989 * Added macro SILC_PACKET_DATALEN which can be used during
990 packet assembling to check whether the data to be added to
991 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
992 len is truncated until it fits it.
994 Added checks for maximum length of channel message payload and
995 private message payload also.
997 Added checks for maximum packet length in server and in
1000 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1001 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1002 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1003 lib/silcclient/client_prvmsg.c.
1005 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1007 * Added silc_server_packet_queue_purge call to the
1008 silc_server_disconnect_remote to assure that all data in the
1009 queue before disconnecting is sent to the network. Affected
1010 file silcd/server.c.
1012 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1014 * Added the deleting of server's own ID cache entry to the
1015 silc_server_free function. Free also everything else that
1016 has been allocated in silc_server_init. The affected file
1019 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Added functions silc_parse_version_string, silc_version_to_num,
1022 and silc_ske_parse_version to parse SILC protocol style version
1023 strings. Affected files lib/silcutil/silcutil.[ch] and
1024 lib/silcske/silcske.[ch].
1026 * Added new configuration params: version_protocol, version_software
1027 and version_software_vendor to specify what version the remote
1028 host must at least be to be able to connect to server. The vendor
1029 string can be regex matched too. Added new function
1030 silc_server_connection_allowed to check maximum number of allowed
1031 connections, and allowed versions for incoming connections.
1032 Affected files are silcd/server.c, server_util.[ch] and
1035 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1037 * Added preliminary support for signals in scheduler. The
1038 signals we care about are now blocked always when the scheduler
1039 is locked. This way we can synchronise the use of signal with
1040 scheduler. It is guaranteed that when signal occurs the scheduler
1041 is not locked, and thus new tasks can be safely added to the
1044 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1045 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1046 Added new platform specific routines
1047 silc_schedule_internal_signals_[un]block and
1048 silc_schedule_internal_signal_[un]register.
1050 Added new functions to SILC Schedule API:
1051 silc_schedule_signal_[un]register. Each signal that application
1052 is going to use should be registered to the scheduler.
1054 Affected files are lib/silcutil/silcschedule.[ch],
1055 lib/silcutil/*/silc*schedule.c.
1057 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Check for unauthenticated client and server in the
1060 silc_server_new_client and silc_server_new_server functions.
1061 Affected file silcd/packet_receive.c.
1063 * Added function silc_string_is_ascii to check whether given
1064 string is 7-bit ASCII string. Affected files are
1065 lib/silcutil/silcutil.[ch].
1067 * Added function silc_id_is_valid_server_id into the
1068 silcd/serverid.c and added checking for valid Server ID's in
1069 silc_server_new_server. The Server ID must always be based
1070 on the server's public IP address.
1072 * Added logging of DISCONNECT packet message in the server.
1073 Affected file silcd/server.c.
1075 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1077 * Changed all library interfaces that use Global RNG to also
1078 accept SilcRng as argument. Affected files are
1079 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1080 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1081 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1082 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1083 lib/silccrypt/rsa.c.
1085 * Added function silc_pkcs_generate_key to the
1086 lib/silccrypt/silcpkcs.[ch] for applications so that they
1087 don't need to do pkcs->pkcs->init calls anymore.
1089 * Remove SilcSocketConnection from the SFTP API since it really
1090 wasn't needed there. The application has the information
1091 saved in its contexts anyway and the SFTP layer doesn't need
1092 know about it. Affected files lib/silcsft/silcsftp.h and
1093 lib/silcsftp/sftp_[server/client].c.
1095 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1098 * Fixed possible buffer overflows in silc_id_render in the
1099 lib/silcutil/silcutil.c.
1101 * On EPOC the global crypto module lists are not used at all
1102 in the crypto library. Added support for using the constant
1103 algorithm list on EPOC. Affected files are
1104 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1107 * Fixed the handling of third parameter of KICKED notify, since
1108 it was mistakenly updated to SILC Protocol 1.0 even though it
1109 is to be included in 1.1. Since it is not in 1.0 it is not
1110 mandatory, and this fix now handles it only if it is provided,
1111 and it is not error if it is not provided. Affected file
1112 lib/silcclient/client_notify.c.
1114 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1119 * Merged with Irssi 0.8.4 from irssi.org CVS.
1121 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1123 * Check for valid socket connection in client entries before
1124 sending any messages. Fixes a crash, but doesn't fix some
1125 other underlaying bug that is lurking there. Affected
1126 file silcd/packet_send.c.
1128 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1130 * $usermode, $cumode and $cumode_space expandos shouldn't do
1131 anything with non-SILC server records. Affected file
1132 irssi/src/silc/core/silc-expandos.c
1134 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1136 * Fixed the silc_net_check_[host/local]_by_sock to support
1137 IPv6 bound sockets as well. Now they can return IPv6 addresses
1138 as well. Affected file lib/silcutil/silcnet.c.
1140 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1141 Affected lib/silcutil/unix/silcunixnet.c.
1143 * Fixed ID rendering (at least on some platforms, not NetBSD)
1144 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1146 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1148 * Added silc_hash_public_key and silc_hash_public_key_compare
1149 functions to be used with SilcHashTable. They can be used to
1150 hash public keys and compare public keys in hash table. Affected
1151 file lib/silcutil/silcutil.[ch].
1153 * Added support for specifying multiple public keys for Client
1154 connection section in server configuration file. This makes it
1155 possible to accept multiple public keys from same host, or to
1156 make a section that accepts any incoming host, and have the
1157 accepted public keys listed in the section.
1159 Added functions silc_sever_[find/get]_public_key, added the
1160 support for this actually to all connection sections but only
1161 the Client section is currently allowed to specify multiple
1164 Affected files are silcd/server.c, server_internal.h,
1165 command.c, protocol.c, server_util.[ch], packet_receive.c.
1167 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1171 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1173 * If silc_debug is TRUE, also output standard logging messages
1174 to stderr with the debug output.
1176 Made silc_log_reset_all() flushing all channels before returning.
1177 Also fixed some documentation typos.
1179 Affected files are lib/silcutil/silclog.[ch].
1181 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1183 * Fixed the server to check correctly the amount of connections
1184 from single host, by checking also the type of the connection.
1185 Fixed also the comparison of number of connections and number
1186 of allowed connections. Affected files are silcd/server.c,
1189 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed the USERS command reply to save the user's mode on the
1192 channel as well. Fixed JOIN command reply to check whether a
1193 client is on channel already and not join it twice. Affected
1194 file lib/silcclient/command_reply.c.
1196 * Added new file silc-expandos.c into irssi/silc/core/ to return
1197 various stuff for various signal for the statusbar etc. updating.
1198 Now Irssi SILC client prints channel user modes etc. on the
1201 * The user mode (like server/router operator changes) is now shown
1202 on the Irssi SILC client's statusbar. The affected files are
1203 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1205 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1207 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1208 to SILC_SCHEDULE_[UN]LOCK macros.
1210 * Added more error printing to logs in server code. Affected
1211 files silcd/server.c and silcd/protocol.c.
1213 * Fixed -S option parsing in Irssi SILC Client. Affected file
1214 irssi/src/silc/core/silc-core.c.
1216 * Added silc_buffer_alloc_size function. Affected file is

1241 * Changed all integer type names:
1242 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1243 to avoid collisions with other libraries using same type names
1246 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1248 * Added `prefer_ipv6' argument to the functions
1249 silc_net_gethostbyname[_async]. If it is TRUE it will return
1250 IPv6 address over IPv4. If FALSE IPv4 address is returned
1251 even if IPv6 address was found. Affected files
1252 lib/silcutil/silcnet.[ch].
1254 * Added support silc_net_create_connection[_async] to fallback
1255 to IPv4 address if IPv6 address could not be used (like if
1256 it doesn't work on a specific system). Affected file in
1257 lib/silcutil/unix/silcunixnet.c.
1259 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Added silc_schedule_reinit function to do the enlarging
1262 of the max tasks handling capabilities of the scheduler.
1263 Affected files lib/silcutil/silcschedule.[ch].
1265 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1267 * Added automatic extern "C" { ... } for C++ compilers so the
1268 application does not need to define them. Affected file
1269 includes/silcincludes.h.
1271 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1272 old name went against naming convention. Applications now
1273 include "silcclient.h" instead of "clientlibincludes.h".
1274 Removed includes/clientlibincludes.h, it is redundant now.
1276 * Renamed includes/version.h to silcversion.h.
1278 * Added really preliminary support for OS/2 into the util
1279 library. Only thread & mutex API is implemented, others
1280 are still to be implemented. Created the lib/silcutil/os2/
1281 directory. Created also file includes/silcos2.h.
1283 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1288 includes/silcbeos.h.
1290 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1292 * Added proper initializations to silc's irssi code, so it's
1293 now possible to load it as module. Affected files
1294 irssi/src/silc/core/silc-core.c,
1295 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1314 * Added `user_count' to the SilcChannelEntry which now tells the
1315 number of users on the channel. The user count is now saved
1316 in normal server of global channels as well. Affected files
1317 silcd/server.c, idlist.h, packet_receive.c and command.c.
1319 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1320 include file utility functions.
1322 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1323 instead of calling directly OS routines.
1325 * Fixed NICK change printing in Irssi SILC Client. Fixed
1326 KICKED notify printing in Irssi SILC Client. Affected file
1327 irssi/src/silc/core/client_ops.c.
1329 * Fixed a NICK change bug in client library, to not recreate the
1330 client_entry->channels hash table everytime nick is changed.
1331 Affected file lib/silcclient/client.c.
1333 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1335 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1336 the SKE interface a bit.
1338 * Fixed padding problem in PKCS#1. The padding was not actually
1339 random since the random number generator was used incorrectly.
1340 This security bug affects only when encrypting with PKCS#1, and
1341 it is not currently used at all in SILC. SILC only use signing
1342 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1344 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1355 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1356 key_exchange_timeout, conn_auth_timeout, connections_max,
1359 Implemented all the new config settings handling in the server.
1361 Optimized the use of SKE Mutual flag usage. Use it only
1362 if connection authentication protocol is not based in public
1365 Renamed all SilcServerConfigSection* to SilcServerConfig*
1366 to have a bit shorter names.
1368 Affected files silcd/serverconfig.[ch], server.[ch], and
1371 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1402 is now done in silc_core_init() which also fixes autoconnecting
1405 Affected files irssi/src/silc/core/silc-core.c,
1406 irssi/src/fe-text/silc.c.
1408 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Added new configuration options and blocks:
1411 keepalive_secs, reconnect_count, reconnect_interval,
1412 reconnect_interval_max, reconnect_keep_trying and
1413 require_reverser_lookup. Added ConnectionParam block, and
1414 implemented the connection parameters when connecting as
1415 initiator and when accepting connections as responder.
1417 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1418 whether given configuration value has been given already.
1420 Affected files silcd/serverconfig.[c], server.[c].
1422 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1423 algorithm parts and created new file silcalgs.conf, that
1424 is now included from the example_silcd.conf.in.
1426 * Optimized the silc_server_connect_to_router_second to take
1427 the connection configuration object from the SilcServerConnection
1428 object instead of finding it during the connecting phase.
1429 Added the configuration object to SilcServerConnection struct.
1430 Affected files silcd/server_internal.h, server.c.
1432 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1434 * Add the client on channel after it was resolved at the
1435 channel message receiving, and it was not already on the
1436 channel. Affected file lib/silcclient/client_channel.c.
1438 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Fixed the public key authentication to allocate always the
1441 destination signature buffer instead of using static buffer.
1442 Affected file silcd/protocol.c.
1444 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1453 config file, allowing both public key and passphrase based
1454 authentication to be set at the same time.
1456 Added `prefer_passphrase_auth' setting in config file which
1457 can be used to set to prefer passwd auth if both passwd and
1458 public key is set. If not set, public key is preferred.
1459 This has effect only when being initiator (responder will try
1462 Added support for authentication with passphrase and public key
1463 at the same time. The passphrase is tried first always since
1464 it is faster to check.
1466 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1468 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1506 * Fixed CUMODE_CHANGE notify handling to change the mode of
1507 correct client. Affected file lib/silcclient/client_notify.c.
1509 * Make silc_rng_alloc fail if it cannot allocate the sha1
1510 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1512 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1514 * Fixed the file transfer's key agreement payload to include
1515 zero port also if the hostname is NULL because it could not
1518 Call file transfer monitor callback now also if error occurs
1519 during key agreement protocol.
1521 Changed the silc_client_file_send interface to return the
1522 SilcClientFileError instead of session id. The session ID
1523 is returned into pointer provided as argument.
1525 Check that the file exists locally before sending the
1526 file transfer request at all.
1528 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1530 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1531 error than can occur while key agreement protocol. Affected
1532 file lib/silcclient/silcapi.h.
1534 * Fixed the event_mode CMODE handler to not crash when mode
1535 is changed and +k mode is set in the channel. Affected file
1536 irssi/src/silc/core/silc-channels.c.
1538 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and

1540 file lib/silcutil/silclog.c.
1542 * Fixed the channel message payload decryption in the function
1543 silc_channel_message_payload_decrypt to not modify the original
1544 buffer before it is verified that the message decrypted
1545 correctly. Otherwise, next time it is called with correct
1546 channel key it won't encrypt since the payload is corrupted.
1547 Affected file lib/silccore/silcchannel.c.
1549 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1554 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1556 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1557 Affected file lib/silcutil/silcnet.c.
1559 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1561 * Fixed a bug in hash table internal routine for traversing
1562 the table with foreach callback. The current entry may
1563 become invalid in the callback but it was referenced after
1564 the callback returned.
1566 Do not allow auto rehashing of hash table during the
1567 silc_hash_table_foreach operation, for same reasons as it is
1568 not allowed for SilcHashTableList. Affected files are
1569 lib/silcutil/silchashtable.[ch].
1571 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1573 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1574 Win32 DLL. extern's in header files are now declared with
1577 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1579 * Fixed private message handling. It used some old code that
1580 caused the client to crash. Affecte file is
1581 lib/silcclient/client_prvmsg.c.
1583 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1585 * Added function silc_client_add_channel,
1586 silc_client_replace_channel_id, and removed functions
1587 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1588 from client library.
1590 * Added cross reference of the joined channels to the
1591 SilcClientEntry, and changed the SilcChannelEntry's
1592 users list to SilcHashTable. The affected files are
1593 lib/silcclient/idlist.[ch].
1595 * Fixed a bug in hash table tarversing. While the hash table
1596 is traversed with SilcHashTableList the table must not be
1597 rehashed. It is now guaranteed that auto rehashable tables
1598 are not rehashed while tarversing the list. Also defined that
1599 silc_hash_table_rehash must not be called while tarversing
1600 the table. Added function silc_hash_table_list_reset that must
1601 be called after the tarversing is over. The affected files are
1602 lib/silcutil/silchashtable.[ch].
1604 * Changed all hash table traversing to call the new
1605 silc_hash_table_list_reset in server and in client library.
1607 * Added function silc_client_on_channel to return the
1608 SilcChannelUser entry if the specified client entry is joined
1609 on the specified channel. This is exported to application as
1610 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1612 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed founder regaining problem with JOIN command on normal
1615 server. The notify for mode change must be sent always and
1616 not only if !cmd->pending. Affected file silcd/command.c.
1618 * Fixed the WHOWAS command's reply sending to support the
1619 lists correctly. Affected file silcd/command.c.
1621 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1623 * When sending JOIN command to router for processing the
1624 sender's old command identifier was not saved back to the
1625 sender's command context, fixed now. The affected file is
1628 * Create the key in JOIN command of the router did not return
1629 the channel key, added check for this. Affected file is
1632 * Fixed a channel ID update bug in JOIN command reply. Do
1633 not directly upgrade the ID but call the function
1634 silc_idlist_replace_channel_id if the ID was changed.
1635 Affected file silcd/command_reply.c.
1637 * Fixed memory leaks from command calling if it would fail.
1638 Affected file silcd/command.c.
1640 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1642 * Applied patches from cras:
1644 Memory leak fixes around libaries, irssi window resize fix,
1645 new silclist.h and silcdlist.h, all extern inline changed to
1648 * Removed dotconf from lib/dotconf, not needed anymore.
1650 * Removed TRQ from lib/trq, not needed anymore.
1652 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1653 with server connections. Later this will be configurable
1654 in config file after new config file is done. Affected file
1657 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1659 * Fixed a crash in server related to channel announcements.
1660 Affected file silcd/server.c.
1662 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Fixed memory leaks in silc_server_create_new_channel*
1665 functions. Affected file silcd/server.c.
1667 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1668 which ID was changed. This way the router will send the
1669 user list for the channel again, and server won't be in
1670 desync in some rare circumstances. Affected file is
1671 silcd/packet_receive.c.
1673 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1675 * Check for NULL socket pointer in the function
1676 silc_server_packet_send_to_channel_real. Affected file
1677 silcd/packet_send.c.

1680 list. Affected file silcd/packet_receive.c.
1682 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1684 * Fixed some header addition to Toolkit distribution in
1685 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1687 * Added lib/silcclient/client_ops_example.h as an template
1688 file for application programmers to quickly start using
1689 the SilcClientOperation functions in their application.
1690 Updated the lib/silcclient/README as well to tell about this
1691 nice file made available.
1693 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1695 * Call silc_server_remove_from_channels when removing client
1696 entry when NO_SUCH_CLIENT_ID was received. Affected file
1697 is silcd/command_reply.c.
1699 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1701 * Added server & router operator statistics updating. Affected
1702 file silcd/packet_receive.c and silcd/command.c.
1704 * Fixed the SERVER_SIGNOFF notify handling on normal server
1705 not to save the history information for clients. Same was
1706 fixed earlier in remove_clients_by_server function, but not
1707 here. Affected file silcd/packet_receive.c.
1709 * Raised the default connection-retry count from 4 to 7 in
1710 server. Affected file silcd/server.h.
1712 * Cancel any possible reconnect timeouts when we start the
1713 key exchange. Affected file silcd/server.c.
1715 * Do not reconnect on connection failure when SCONNECT was
1716 given. Affected files silcd/server.[ch].
1718 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1720 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1722 * Fixed the NICK command to always give the unformatted
1723 nickname to the one giving the NICK command. If unformatted
1724 nickname is cached already it will be formatted and the
1725 local entry will always get the unformatted nickname.
1726 Affected file lib/silcclient/idlist.c.
1728 * Fixed some double frees from client library commands.
1729 Affected file is lib/silcclient/command.c.
1731 * Fixed CUMODE command in server to assure that no one can
1732 change founder's mode than the founder itself, there was a
1733 little bug. Affected file silcd/command.c.
1735 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Removed the SilcClientCommandDestructor from the client
1738 libary, it is not needed anymore. Affected files are
1739 lib/silcclient/silcapi.h, command[_reply].[ch],
1740 client_notify, idlist.c.
1742 * Fixed GETKEY command to first resolve client, and then
1743 resolve the server only if the client was not found, instead
1744 of resolving both at the same time. Affected file is
1745 lib/silcclient/command.c.
1747 * Added silc_client_start_key_exchange_cb and lookup the
1748 remote hostname and IP address before starting the key
1749 exchange with server. The affected file is
1750 lib/silcclient/client.c.
1752 * The server's public key is now saved using the IP address
1753 of the server and not the servername for the filename.
1754 The hostname public key filename is checked as an fall back
1755 method if the IP address based filename is not found.
1757 Fixed the GETKEY command to save the fetched server key
1758 in correct filename.
1760 Print the remote server's hostname now when new key is
1761 received during connection process. Affected file is
1762 irssi/src/silc/core/client_ops.c.
1764 * Return always our own public key to the client if it asks
1765 for it with GETKEY command. Affected file silcd/command.c.
1767 * Removed the use_auto_addr variable from default config
1768 file since it was in wrong section. Affected file is
1771 * Fixed TOPIC_CHANGE notification to not route it when it
1772 was sent using silc_server_send_notify_to_channel function.
1773 Affected file silcd/command.c.
1775 * Fixed silc_server_send_notify_kicked to send the kicker's
1776 Client ID also, it was missing. Affected files are
1777 silcd/command.c, silcd/packet_send.[ch].
1779 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1781 * Do not save client history information in SERVER_SIGNOFF.
1782 Fixes the bug in normal server that it does not detect
1783 the client becoming valid after the server becomes back
1784 online. Affected file silcd/server_util.c.
1786 * Added `sock_error' field into the SilcSocketConnection
1787 context. When error occurs during socket operation (read
1788 or write) the error is saved. Added also new function
1789 silc_socket_get_error to return human readable socket error
1790 message. Affected files are lib/silcutil/silcsockconn.[ch],
1791 lib/silcutil/unix/silcunixsockconn.c, and
1792 lib/silcutil/win32/silcwin32sockconn.c.
1794 * The server now prints the socket error message in the
1795 signoff for client. Affected file silcd/server.c.
1797 * Fixed the `created' channel information sending from router
1798 to server in JOIN command. Checks now whether the channel
1799 really was created or not and set it according that.
1801 Fixed the JOIN command to use the client entry's current
1802 ID during the joining procedure instead of the one it sent
1803 in the command (it is checked though), since it can change
1804 between the packet processing and command processing, and
1805 would just case unnecessary pain in the client end. Affected
1806 file silcd/command.c.
1808 * Fixed a channel key payload sending to use correct channel
1809 ID when the server was forced to change the channel's ID by
1810 router. Router sent the key payload with the old Channel ID.
1811 Affected file silcd/packet_receive.c.
1813 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * Call silc_server_save_channel_key only if the key payload
1816 was provided in the JOIN command's command reply. Affected
1817 file silcd/command_reply.c.
1819 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Fixed silc_mp_sizeinbase to return the value correctly with
1822 MPI. Affected file lib/silcmath/mp_mpi.c.
1824 * Fixed the stop_server signal to correctly stop the scheduler
1825 and gracefully stop the server when SIGTERM or SIGINT signals
1826 are received. Affected file silcd/silcd.c.
1828 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1830 * Simple handling of TERM and HUP signals. Also added some log
1831 flushing call around. Affected file is
1834 * Fixed small bugs in silclog.c. Now buffering output will take
1835 effect after 10 seconds since startup: This will ensure that
1836 no important startup messages are lost. Also output redirection
1837 will preserve original format ([Date] [Type] message).
1838 Affected file is lib/silcutil/silclog.c.
1840 * Added two options to the config file, in the logging section:
1841 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1842 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1844 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * Do not print the warning about log files not being initialized
1847 more than once to avoid excess logging. Affected file is
1848 lib/silcutil/silclog.c.
1850 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1851 the SIM copying in make install in Makefile.am.pre.
1853 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1855 * Rewritten silclog APIs. Globally interesting changes follows:
1856 silc_log_set_files() changed to silc_log_set_file().
1857 silc_log_set_callbacks() changed to silc_log_set_callback().
1858 ROBOdoc documented silclog header file.
1859 SilcLogCb now returns bool to wether inihibit the default
1860 handler or not (to keep the old behaviour return always TRUE).
1861 The new APIs should also fix the problem of the
1862 silcd_error.log file that was written in the current directory.
1865 Log files streams will remain opened after silc_log_set_file()
1866 call, means less CPU usage notably on high traffic servers.
1867 File streams are now full buffered, and flushed to the disk
1868 every 5 minutes, lesses HD activity and CPU usage.
1869 Messages can be redirected, allowing admins to configure
1870 one single logfile for all server messages.
1871 the silc_log_quick global variable to activate fast-logging.
1872 Affected files lib/silcutil/silclog.[ch]
1874 * Changed some code to conform new silclog APIs. Affected
1875 files are doc/example_silcd.conf.in, silcd/server.c
1876 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1879 * Fixed a memory leak that could occur in some situations.
1880 Affected file silcd/serverconfig.c.
1882 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * Added the silc_client_del_client to remove the client from
1885 all channels as well. Affected file lib/silcclient/idlist.c.
1887 * Fixed the client library to correctly remove the client
1888 from all channels when the client entry is being destroyed.
1889 Affected file lib/silcclient/client_notify.c, command.c.
1891 * Added auto-nicking support to the client library. If the
1892 applicatio now sets client->nickname it will be sent to the
1893 server after connecting by the library. This way for example
1894 SILCNICK (or IRCNICK) environment variables will have effect
1895 and always change the nickname automatically to whatever
1896 it is wanted. Affected file lib/silcclient/client.[ch].
1898 * Renamed silc_server_command_bad_chars to the
1899 silc_server_name_bad_chars and moved it to the
1900 silcd/server_util.[ch]. Added also new function
1901 silc_server_name_modify_bad to return nickname that
1902 includes bad characters as new nickname without those
1903 bad characters. This check and modify is now used in
1904 silc_server_new_client when the username is initially set
1905 as nickname, so it must be checked to be valid nickname.
1906 Affected file silcd/packet_receive.c.
1908 * The nickname length is now taken from the packet for real
1909 and not trusted to strlen() since it clearly can return
1910 wrong length for nickname including bad characters. This
1911 also applies to channel names. Affected file silcd/command.c.
1913 * Removed the lib/silcsilm/modules directory. Modules are now
1914 compiled into the lib/silcsim. Fixed the copying of the
1915 modules to follow symbolic links in Makefile.am.pre.
1917 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1919 * Fixed silc_string_regexify list creation. Fixes bugs with
1920 BAN and INVITE commands in server. The affected file is
1921 lib/silcutil/unix/silcunixutil.c.
1923 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Removed the command destructor entirely from the server's
1926 command and command reply routines. It is not needed, and
1927 its usage was buggy and caused crashes. Affected files are
1928 silcd/command[_reply].[ch].
1930 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Cancel protocol and NULL sock->protocol if timeout
1933 occurred during protocol. Affected file silcd/server.c.
1935 * Cancel protocol timeouts always before calling the final
1936 callback, to assure that after final callback is called
1937 no other state will be called for the protocol anymore.
1938 Affected file silcd/protocol.c.
1940 * Print error log if incoming connection configuration could
1941 not be found. Affected file silcd/server.c.
1943 * Fixed JOIN command to correctly save the founder mode
1944 to the client on normal SILC server, when the channel
1945 was created by the router. Affected file silcd/command.c.
1947 * Fixed LIST command (hopefully) to send correct reply
1948 packets. Affected file silcd/command.c.
1950 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * The silc_packet_receive_process now returns FALSE if the
1953 read data was invalid packet, and TRUE if it was ok.
1955 The server now checks that if unauthenticated connection
1956 sends data and its processing fails the server will close
1957 the connection since it could be a malicious flooder.
1959 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1961 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1963 * Make sure the warning about error opening a log file is
1964 printed only once and not everytime it fails (produces
1965 too much useless log). Affected file lib/silcutil/silclog.c.
1967 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1969 * Made the silc_server_daemonise() function more readable.
1970 Affected file silcd/server.c.
1972 * Pid file is now optional, the user may comment it out from
1973 the config file. Removed define SILC_SERVER_PID_FILE, we
1974 don't need a default any longer. Affected file
1975 configure.in.pre, lib/Makefile.am.pre.
1977 * Make some use of the pid file. The server now dies at startup
1978 if it detects a valid pid file on his path. The server would
1979 die anyway in this circumstance, because of the bind() failure.
1980 Affected file silcd/silcd.c.
1982 * No longer compiling lib/dotconf.
1984 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Fixed JOIN command parsing not to crash. Affected file
1987 lib/silcclient/command.c.
1989 * Fied the NICK_CHANGE notify to add the new client entry
1990 even it is resolved. This removes an <[unknown]> nick
1991 thingy bug in the client. Affected file is
1992 lib/silcclient/client_notify.c.
1994 * Do not try to allocate 0 bytes (efence does not like it)
1995 in lib/silccore/silccomand.c when encoding payload.
1997 * Do not take IRCNICK as nickname in Irssi SILC client since
1998 it is not possible to set nickname before hand connecting
1999 the server (TODO has an entry about adding auto-nicking
2002 * Changed the silc_server_command_pending to check whether
2003 there already exists an pending entry with the specified
2004 command, command identifier and pending callback. This is
2005 to fix IDENTIFY and WHOIS related crashes that may register
2006 multiple pending commands with same identifier. Affected
2007 file silcd/command.c.
2009 * Fixed the server to reconnect to the router even if it
2010 was already reconnecting and EOF was received. This to
2011 fix a possibility that the server wouldn't ever try to
2012 auto-reconnect to the router. Affected file silcd/server.c.
2014 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Fixed the server's password authentication to use the
2017 length of the locally saved password, and not the one
2018 sent in the packet. Affected file silcd/protocol.c.
2020 * Fixed same password authentication problem in the
2021 Authentication Payload handling routines in
2022 lib/silccore/silcauth.c.
2024 * Yet another password authentication problem fixed with
2025 channel password handling in silcd/command.c.
2027 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * If first character of string in silc_parse_userfqdn is '@'
2030 then do not parse it. Affected file is
2031 lib/silcutil/silcutil.c.
2033 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Fixed minor bug in IDENTIFY command reply sending, which
2036 caused various weird problems during JOIN when it was
2037 resolving names for users. Affected file silcd/command.c.
2039 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Fixed the IDENTIFY command reply sending to chech better valid
2042 clients. It was possible to send incomplete list of replies.
2043 Affected file silcd/command.c.
2045 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added silc_client_command[s]_[un]register functions now to
2048 dynamically register the commands in client library. Removed
2049 the static table of commands. This allows the client library
2050 to call commands without causing the application to know about
2051 what commands library has called.
2053 Removed the INFO command reply kludge to detect when the command
2054 was called by library. Now library use its own command reply
2055 function for INFO command.
2057 Added function silc_client_command_call to call a command.
2058 Application can use it to call command, not access the structure
2061 Now all commands that are sent by the client library (not
2062 explicitly sent by application) use own command reply functions.
2064 Affected files around lib/silcclient/ and in
2065 irssi/src/silc/core/.
2067 * Fixed the WHOIS command reply sending to chech better valid
2068 clients. It was possible to send incomplete list of replies.
2070 Fixed the WHOIS and IDENTIFY to send the request to router
2071 if normal server did not do it and did not find any results.
2073 Affected file silcd/command.c.
2075 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Moved the internal data from SilcClient context into its
2078 own file, not accesible to application. Affected files
2079 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2080 and other files in client library.
2082 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Added doc/examples installation target in Makefile.am.pre.
2087 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2090 commands the found client entry will be removed from the
2091 cache, after notifying application about the error. Affected
2092 file lib/silcclient/command_reply.c.
2094 * Changed the /MSG to check for exact nickname user gave, and
2095 not let `nick' match `nick@host' if it is only one found. Now,
2096 user must type the exact nickname (like nick@host2) even if
2097 there are no more than one same nicks found. This is to avoid
2098 a possibility of sending nickname to wrong nickname since
2099 `nick' could match `nick@host'. Affected file is
2100 irssi/src/core/silc-servers.c.
2102 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Do not print "you are now server operator" or similar when
2105 giving /away command. Affected files are
2106 irssi/src/silc/core/client_ops.c, silc-servers.h.
2108 * Made the silc_server_command_pending_error_check to send
2109 the same command reply payload it received back to the
2110 original sender of the command. This way all arguments
2111 that was received by the server will be received by the
2112 client too. Affected file silcd/command.c.
2114 * Added the silc_idcache_add to return the created cache entry
2115 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2117 * Add global clients to expire if they are not on any channel.
2118 This is because normal server will never know if they signoff
2119 if they are not on any channel. The cache expiry will take
2120 case of these entries. This is done by normal servers only.
2121 The affected files are silcd/command_reply.c,
2122 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2124 * If server receives invalid ID notification for WHOIS or
2125 IDENTIFY and the ID exists in the lists, it is removed.
2126 Affected file silcd/command_reply.c.
2128 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2129 in client then client entry that it matches is searched and
2130 the nickname is printed on the screen for user. Affected
2131 file irssi/src/silc/core/client_ops.c.
2133 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Use cache entry expire time in the LIST command reply to
2136 purge old entries from the cache after the LIST command
2137 reply has been received. This way we don't have non-existent
2138 entries in the cache for too long. Affected file is
2139 silcd/command_reply.c.
2141 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * If we are normal server, and we've not resolved client info
2144 in WHOIS or IDENTIFY from router, and it is global client,
2145 we'll check whether it is on some channel. If it is not
2146 then we cannot be sure about its validity and will resolve it
2147 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2148 file silcd/command.c.
2150 * Search channel by name (if possible) rather than by ID
2151 in IDENTIFY command's command reply. Affected file is
2152 silcd/command_reply.c.
2154 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2157 Updated specs and implemented it. Affected file silcd/command.c,
2158 silcd/packet_send.c and silcd/packet_receive.c.
2160 * Implemented the <founder auth> payload handling in the JOIN
2161 command. If provided all conditions for channel joining
2162 except requirement to provide correct passphrase can be
2163 overrided by the channel founder. Updated the protocol specs.
2164 Affected file silcd/command.c.
2166 Added support for founder auth in JOIN command in client
2167 library. Fixed the parsing of the JOIN command now to support
2168 all options as they should be. The affected file is
2169 lib/silcclient/command.c.
2171 * Optimized the WHOIS and IDENTIFY commands to send the request
2172 to router only if it includes nicknames or other names. If
2173 they include only IDs then check the local cache first before
2174 routing. Affected file is silcd/command.c.
2176 * Added channels topic announcements. Affected file is
2177 silcd/packet_receive.c and silcd/server.c.
2179 * Fixed the silc_server_send_notify_topic_set to really destine
2180 the packet to channel. Affected file silcd/packet_send.c.
2182 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2183 library. Affected file lib/silcclient/client_notify.c.
2185 * Added UMODE announcements. Affected file silcd/server.c.
2187 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Memory leak fixes in:
2191 lib/silcutil/silcsockconn.c
2192 lib/silcske/silcske.c
2193 lib/silcske/groups.c
2195 lib/silccrypt/silcpkcs.c
2196 lib/silccore/silccommand.c
2197 lib/silccore/silcidcache.c
2202 * ROBOdoc documented the lib/silcske/groups.h file and a
2203 bit changed the interface for better.
2205 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2207 * Update the client entry context in the ID cache after
2208 nick change. Affected file lib/silcclient/command.c.
2209 Fixes the CUMODE command when regaining founder privileges,
2210 and a little WHOIS problem.
2212 * Fixed silc_net_gethostbyname to correctly call the
2213 inet_ntop. Affected file lib/silcutil/silcnet.c.
2215 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2217 * Added IPv6 support checking to the configure.in.pre, added
2218 also --enable-ipv6 option to override the check. Affected
2219 file configure.in.pre.
2221 * The silc_thread_create now calls the start function
2222 directly if threads support is not compiled in. Removes
2223 ugly #ifdef's from generic code. Affected files are
2224 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2226 * Added silc_net_gethostby[name/addr]_async to asynchronously
2227 resolve. Affected files are lib/silcutil/silcnet.[ch].
2229 * Added support for rendering IPv6 based server, client and
2230 channel IDs. Affected file lib/silcutil/silcutil.c.
2232 * Added support for creating IPv6 based server IDs. Affected
2233 file is silcd/serverid.c.
2235 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2237 * Added silc_net_gethostby[addr/name] into the
2238 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2239 routines. Added silc_net_is_ip[4/6]. Affected file is
2240 lib/silcutil/unix/silcunixnet.c. All routines that take
2241 address as argument now supports both IPv4 and IPv6 addresses.
2243 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2245 * Fixed LIST command reply sending in server. Affected file
2248 * Server now sends the kicker's client ID in the KICK notify
2249 to the kicked client. Affected file silcd/command.c.
2251 * The client library now parses the kickers client ID and
2252 UI displays it. Affected files lib/silcclient/client_notify.c
2253 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2255 * Made all payload parsing function prototypes consistent.
2256 They all take now const unsigned char * and uint32 pair as
2257 the payload data instead of SilcBuffer. Changes all around
2258 the source tree. Other unsigned char* -> const unsigned char*
2259 changes around the tree as well.
2261 * Optimized SFTP client and server packet sending not to
2262 allocate new buffer for each packet but to recycle the
2263 first allocated buffer. Affected files are
2264 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2266 * Optimized the SFTP client to use SilcList instead of
2267 SilcDList for requests, because it is faster. Affected file
2268 is lib/silcsftp/sftp_client.c.
2270 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2271 into lib/silccore/silcid.[ch].
2273 Renamed silcpayload.[ch] into silcargument.[ch].
2275 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * If client entry is deleted with active key agreement
2278 session, abort the session.
2280 The silc_client_abort_key_agreement now calls the completion
2281 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2283 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2286 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Don't use __restrict in older GCC's. Affected file is
2289 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2291 * silc_net_localhost now attempts to reverse lookup the
2292 IP/hostname. Affected file lib/silcutil/silcnet.c.
2294 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2295 command. It can be used to gain founder privileges at
2296 the same time when joining the channel.
2298 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2299 kicker's client ID as well. Updated protocol specs.
2301 Defined that the server must send SILC_COMMAND_IDENTIFY
2302 command reply with error status to client who sent
2303 private message with invalid client ID.
2305 Updated the protocol specification.
2307 * Added silc_server_send_command_reply to send any
2308 command reply. Affected file silcd/packet_send.[ch].
2310 * Added silc_id_payload_encode_data to encode ID payload
2311 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2313 * The server now send IDENTIFY command reply with error
2314 status if client ID in private message is invalid. Affected
2315 file silcd/packet_receive.c.
2317 * Save the server key file with server's IP address in
2318 the filename instead of hostname. The affected file is
2319 irssi/src/silc/core/client_ops.c.
2321 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2326 * Added libtool support for compiling shared objects in
2327 lib/silcsim. Affected file configure.in.pre and
2328 lib/silcsim/Makefile.am. Original patch by cras.
2330 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Pid file configuration, and server's config file fixes
2333 patch by toma. Updated CREDITS file.
2335 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Fixed silc_client_channel_message to not try to decrypt
2338 the message twice if it resolved the destination client
2339 information. This could cause of dropping one channel
2340 message. Affected file lib/silcclient/client_channel.c.
2342 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2345 lib/silcclient/client.c. This function is used when the SILC
2346 Client is run under some other scheduler, or event loop or
2347 main loop. On GUI applications, for example this may be
2348 desired to used to run the client under the GUI application's
2349 main loop. Typically the GUI application would register an
2350 idle task that calls this function multiple times in a second
2351 to quickly process the SILC specific data.
2353 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2355 * Fixed silc_server_drop() for dropping the supplementary
2356 groups as well, this could cause a security hole on some
2359 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2364 * Write PID file after dropping privileges. Added -F option
2365 to run server on foreground. A patch by debolaz.
2366 Affected files silcd/server.c, silcd/silcd.c.
2368 * Fixed MOTD to return the MOTD file server name. Affected
2369 file silcd/command.c.
2371 * Added INFO command reply handling to the Irssi SILC Client.
2372 Affected file irssi/src/silc/core/client_ops.c.
2374 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Fixed the silc_idcache_list_* routines to really support
2377 the dynamic list. Fixes a crash. Affected file is
2378 lib/silccore/silcidcache.c.
2380 * Fixed the LIST command reply to really call LIST command's
2381 pending callbacks. Affected file silcd/command_reply.c.
2383 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Update conn->local_entry->nickname after giving NICK
2386 command. Affected file lib/silcclient/command.c.
2388 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2390 * Added the [pid] option to the silcd configuration file
2392 Affected files: serverconfig.[ch] and silcd.c
2394 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Save fingerprint in WHOIS command reply in server.
2397 Affected file silcd/command_reply.c.
2399 * Fixed NICK commands pending callback registration.
2400 Affected file lib/silcclient/command.c.
2402 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Use ++server->cmd_ident when sending commands in server,
2405 instead of random number. Affected file silcd/command.c.
2407 * Fixed GETKEY command reply to call actually GETKEY pending
2408 command callbacks. Affected file silcd/command_reply.c.
2410 * A bit stricter check for nicknames. Check for same nickname
2411 in NICK command also. Affected file silcd/command.c.
2413 * Do not call INFO command everytime client ID changes, only
2414 during first connecting. Affected file lib/silcclient/client.c.
2416 * Set the new nickname only after successful command reply for
2417 NICK command is returned by server. Affected file
2418 lib/silcclient/command.c.
2420 * Remove nicknames from nicklist during server_signoff notify.
2421 Should fix /NAMES bit more. The affected file is
2422 irssi/src/silc/core/silc-channels.c.
2424 * Added `fingerprint' field to the SilcIDListData in the
2425 silcd/idlist.h to hold the fingerprint of the client's
2428 Send the fingerprint of the client's public key in WHOIS
2431 Affected files silcd/command.c, and silcd/idlist.[ch].
2433 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2434 create fingerprint from given data.
2436 * Show the fingerprint of the client's public key in WHOIS.
2437 Affected files irssi/src/module-formats.[ch] and
2438 irssi/src/silc/core/client_ops.c.
2440 * Format the multiple same nicknames also during JOIN and
2441 NICK_CHANGE notifys. Affected file is
2442 lib/silcclient/client_notify.c.
2444 * Do not print error on screen for invalid private message
2445 payload since it can come if someone is sending private
2446 messages with wrong key. Affected file
2447 lib/silccore/silcprivate.c.
2449 * Fixed multiple concurrent /PING crash. Affected file
2450 lib/silcclient/command.c.
2452 * Changed the wrong ID encoding. All IP addresses must be
2453 in MSB first order in encoded format. They were encoded
2454 wrong and was in LSB format. Affected files are
2455 silcd/serverid.c, lib/silcutil/silcutil.c.
2457 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2459 * Call the `connect' client operation through the scheduler
2460 in case of error. Affected file lib/silcclient/client.c.
2462 * Call the `failure' client operation even if the error
2463 occurred locally during a protocol. Affected file is
2464 lib/silcclient/protocol.c.
2466 * Added support of sending LIST command to router from normal
2467 server. This way normal server can get list of all channels
2468 in the network too. Fixed the channel list sending in the
2469 server too. Affected files are silcd/command.c, and
2470 silcd/command_reply.[ch].
2472 * Added silc_server_update_channels_by_server and
2473 silc_server_remove_channels_by_server. They are used during
2474 disconnection of primary router and in backup router protocol.
2475 Affected file silcd/server_util.[ch], silcd/server.c and
2476 silcd/server_backup.c.
2478 * Fixed channel adding to global list in IDENTIFY command
2479 reply in server. Affected file silcd/command_reply.c.
2481 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * If the incoming packet type is REKEY or REKEY_DONE process
2484 that packet always synchronously. Fixes yet another MAC
2485 failed error on slow (dialup) connections. Affected file
2486 lib/silcclient/client.c and silcd/server.c.
2488 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Call check_version SKE callback for initiator too. Affected
2491 file lib/silcske/silcske.c.
2493 * Implemented fix for security hole found in the SKE that was
2494 fixed in the specification few days back; the initiator's
2495 public key is now added to the HASH value computation.
2496 Added backwards support for the old way of doing it too, for
2497 old clients and old servers. Affected file is
2498 lib/silcske/silcske.c.
2500 * Enabled mutual authentication by default in SKE. If initiator
2501 is not providing mutual authentication the responder will
2502 force it. This will provide the proof of posession of the
2503 private key for responder. The affected files are
2504 lib/silcclient/protocol.c and silcd/protocol.c.
2506 * Do not cache anymore the server's public key during SKE.
2507 We do mutual authentication so the proof of posession of
2508 private key is done, and if the server is authenticated in
2509 conn auth protocol with public key we must have the public
2510 key already. Affected file silcd/protocol.c.
2512 * Added new global debug variable: silc_debug_hexdump. If
2513 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2514 file lib/silcutil/silclog.[ch].
2516 * Fixed compilation warning due to char * -> const char *.
2517 Affected files lib/silcutil/silcnet.h, and
2518 lib/silccore/silcauth.[ch].
2520 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Fixed CMODE command when new channel key was created. If
2523 the creation failed the old key was removed. Next time giving
2524 same command would crash the server since the old key was
2525 freed already. Affected file silcd/command.c.
2527 * Fixed the silc_server_announce_get_channels to not crash
2528 on reconnect. Affected file silcd/server.c.
2530 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Added silc_log_set_debug_string function to set a regex
2533 string to match for debug output. Only the function names,
2534 or filenames matching the given debug string is actually
2535 printed. This way it is possible to filter out those debug
2536 strings that user is not interested in.
2538 Fixed a bug in silc_string_regexify.
2540 Affected files lib/silcutil/silclog.[ch], and
2541 lib/silcutil/unix/silcunixutil.c.
2543 * Changed the -d options in both server and Irssi SILC client
2544 to take the debug string as argument. Affected files
2545 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2547 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Added silc_hash_babbleprint to create a Bubble Babble
2550 Encoded fingerprint. The encoding is developed by Antti
2551 Huima (draft-huima-babble-01.txt), and it creates human
2552 readable strings out of binary data. Affected file
2553 lib/silccrypt/silchash.[ch].
2555 * Print the babble print now in addition of fingerprint as well
2556 in Irssi SILC client. Affected files are
2557 irssi/src/fe-common/silc/module-formats.[ch],
2558 irssi/src/fe-common/silc/core/client_ops.c.
2560 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed a security problem found in SKE. The initiator's
2563 public key too is now added to the HASH hash value creation
2564 which is signed by the responder to create the SIGN value.
2565 This will prevent anyone in the middle to lie to the responder
2566 about the initiator's public key. If this is done now, the
2567 man in the middle will get caught. Updated the protocol
2570 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Better installation directory handling. Configure module
2573 paths and other paths automatically to example_silc* files
2574 in doc/. A patch by toma.
2576 * Fixed compiler warning from MPI library, and from SILC RNG.
2579 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2580 It can be configured with ./configure. A patch by toma.
2582 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Find correct make to use in prepare-clean. A patch by
2585 toma. Affected file prepare-clean.
2587 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2589 * Added irssi variables use_auto_addr, auto_bind_ip,
2590 auto_bind_port and auto_public_ip.
2592 * Changed the interface for silc_client_send_key_agreement
2593 in lib/silcclient/silcapi.h
2597 irssi/src/silc/core/silc-core.c
2599 lib/silcclient/silcapi.h
2600 irssi/src/silc/core/silc-channels.c
2601 lib/silcclient/client_keyagr.c
2604 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Added silc_pkcs_public_key_compare to compare two
2607 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2609 * Check that the client who set the founder mode on the
2610 channel is the same client that is giving the founder
2611 mode to itself. It is done by comparing the saved public
2612 key (it is saved even in the authentication is passphrase).

2621 client library. Affected file lib/silcclient/client.c.
2623 * Fixed the silc_client_packet_parse to not to increase
2624 the packet sequence number if the conn->sock and the
2625 current socket connection is not same. This can happen
2626 for example during key agreement when the conn includes
2627 multiple socket connections (listeners). Affected file
2628 lib/silcclient/client.c.
2630 * The sender of the file transfer request now provides also
2631 the pointer (listener) for the key exchange protocol. If
2632 the listener cannot be created then it sends empty key
2633 agreement and lets the receiver provide the listener.
2635 Added `local_ip' and `local_port' arguments to the
2636 silc_client_file_send. If they are provided they are used,
2637 if not then it will attempt to find local IP address, if
2638 not found or bind fails then the remote client will provide
2641 Affected files are lib/silcclient/client_ftp.c and
2642 lib/silcclient/silcapi.h.

2651 of the client's public key (if the proof of posession of the
2652 corresponding private key is verified by the server).
2653 Updated to the protocol specification.
2655 * Added support of receiving the client's public key's
2656 fingerprint in command reply in client library. Affected
2657 file is lib/silcclient/command_reply.c, and
2658 lib/silcclient/idlist.[ch].

2717 preserve the WHOWAS info for the client. Affected file
2718 silcd/server_util.c.
2720 * Fixed SERVER_SIGNOFF notify handling in the server. The
2721 server is now able to process incoming SERVER_SIGNOFF notify
2722 for a server that it doesn't even know about. It will remove
2723 the clients provided in the notify. Affected file
2724 silcd/packet_receive.c.
2726 * Check for partial packet in data queue after every packet that
2727 was found from the queue. Return and wait for more data if
2728 there is partial data in queue. Affected file is

2750 * Added silc_rng_global_get_byte_fast to get not-so-secure
2751 random data as fast as possible. Random data is read from
2752 /dev/urandom if available and from the SILC RNG if not
2753 available. It is used in padding generation. Affected file
2754 lib/silccrypt/silcrng.[ch].
2756 * All packets in client library are now processed synchronously.
2757 Optimized packet processing a lot. Affected file
2758 lib/silcclient/client.c.

2771 be found by the first it cannot be found at all. Affected
2772 file lib/silcclient/client_notify.c.
2774 * Fixed WHOWAS command reply calling. Affected file
2775 lib/silcclient/command_reply.c.
2777 * Removed all references to silc_idlist_get_client from the
2778 Irssi SILC client since that call is internal call used by
2779 the library. The Irssi SILC client will use now client
2780 retrieval functions found in silcapi.h.
2782 * Fixed a bug in resolving nickname info before sending
2783 private message. It used freed memory. Affected file
2784 irssi/src/silc/core/silc-servers.c.

2806 Affected file lib/silcutil/silcnet.[ch].
2808 * If key exchange or rekey protocol is active for a connection
2809 parse all packets syncronously since there might be packets
2810 in packet queue that we are not able to process without first
2811 processing packets before them. Affected file silcd/server,
2812 lib/silcclient/client.c.
2814 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2815 whether library should continue processing the packet.
2816 Affected file lib/silccore/silcpacket.h.

2889 * Call the silc_server_udpate_servers_by_server in the
2890 primary router that comes back online in the backup resuming
2891 protocol. Otherwise it routes packets wrong. Affected file
2892 silcd/server_util.[ch], silcd/server_backup.c.
2894 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2897 lib/silcutil/silcbuffmt.[ch].

2902 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2903 length for maximum padding up to 128 bytes). Affected
2904 file lib/silccore/silcpacket.h.
2906 * Removed all backwards support for old 0.5.x MAC thingies.
2907 The SILC packet header change makes it impossible to be
2908 backwards compatible.
2910 * Send the ENDING packet with timeout in the backup resuming
2911 protocol. This is to assure that all routers has connected
2912 to the primary router. Affected file silcd/server_backup.c.
2914 * Changed the RNG to take the first IV from random data. It
2915 used to take it from zero actually. Changed the RNG also

2939 * Allow backup router to announce servers. All servers
2940 announced by backup router are added to the global list
2941 automatically. Update hte server's socket to our primary
2942 router also when backup router announces a server.
2943 Affected file silcd/packet_receive.c.
2945 * Do not update the client->router in the function
2946 silc_server_udpate_clients_by_server if the client is on
2947 global list. We might fail to find any specific server
2948 for locally connected clients and local cell clients. They
2949 should still use the `from' and not `to' as client->router.
2950 This fixes backup router resuming protocol. Affected file
2951 silcd/server_util.c.
2953 * Decrease channel statistics count only if the channel
2954 deletion worked. Affected files are silcd/server.c and
2955 silcd/server_util.c.
2957 * Added silc_server_update_servers_by_server to update origin
2958 of all server entries. Used during backup router protocol.

2975 to the router it came from. Affected file is
2976 silcd/packet_send.c. Fixed memory leak too.
2978 * Announce informations for incoming router connection, but
2979 only after checking if it is replaced by backup router.
2980 Affected file silcd/packet_receive.c.

2994 Affected file silcd/packet_send.c.
2996 * Changed the SFTP Filesystem interface. Changed the
2997 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2998 the filesystem operation function. The SilcSFTPFilesystem
2999 is now a context that is allocated by all filesystem allocation
3000 functions and it already includes the operations structure
3001 and filesystem specific context. It is given as argument
3002 now to the silc_sftp_server_start. This made the interface
3003 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3004 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3006 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Changed the backup router adding and getting interfaces
3009 in the server. The router that will be replaced by the

3129 of the internet draft is lib/silccore/silcpacket.h.
3131 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3132 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3133 is used as part of backup router protocol when the primary
3134 router of the cell is back online and wishes to resume
3135 the position as primary router.
3137 * Redefined the MAC generation keys in the protocol. The
3138 same key is not used anymore in both direction. Both
3139 direction will now use different keys for sending and
3140 receiving. This fixes a potential security flaw. This
3141 change causes incompatibilities in the protocol.
3143 * Redefined also the MAC computation from the packet.
3144 An packet sequence number is now added to the MAC
3145 computation. This prevents possible replay attacks against
3146 the protocol. This change too causes incompatibilities
3149 Added `sequence' field to the SilcPacketContext to hold
3150 the current sequence number for the packet.
3152 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Added `created' field to the SilcIDListData in the file
3155 silcd/idlist.h to indicate the time when the entry was
3158 * Added `created' field to the SilcChannelEntry too. Affected
3159 file silcd/idlist.h.
3161 * Added `creation_time' aguments to all the announcement functions
3162 in the server. If it is provided then only the entries that
3163 was created after the provided time frame are actually
3164 announced. Affected file silcd/server.[ch].
3166 * The protocol says that the Channel ID's IP address must be
3167 based on the router's IP address. Added check for this in
3168 the silc_server_new_channel when processing incoming New Channel
3169 Payload. Affected file silcd/packet_receive.c.
3171 * Print out the correct version with --version in SILC client.
3172 Affected file irssi/src/silc/core/silc-core.c.
3174 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Fixed WHOWAS command to check for completnes of the client
3177 entry always, not just when the command is coming from client.
3178 Affected file silcd/command.c.
3180 * Added new function silc_server_packet_queue_purge to purge the
3181 outgoing data queue to the network. After the function returns
3182 it is guaranteed that the outgoing packet queue is empty.
3183 Affected file silcd/packet_send.[ch].
3185 * Purge the outgoing packet queue in the rekey protocol's final
3186 callback to assure that all rekey packets go to the network
3187 before quitting the protocol. Affected file silcd/server.c.
3189 * Added silc_client_packet_queue_parse as similar function as
3190 in server to the client library. The affected file is
3191 lib/silcclient/client.c.
3193 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * Splitted silcd/server.c and created silcd/server_util.[ch]
3196 for utility functions.
3198 * Added new socket flag SILC_SF_DISABLED to indicate that the
3199 connection is open but nothing can be sent to or received from
3200 the connection. Affected file lib/silcutil/silsockconn.[ch].
3201 The checking for disabled socket is checked in the low level
3202 silc_socket_write and silc_socket_read functions.
3204 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Allow only nicknames and channel names that fits into the
3207 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3209 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * When processing JOIN command reply in server check that if
3212 the channel exists in our global list we'll move it the local
3213 list. Affected file silcd/command_reply.c.
3215 * Fixed the check whether client is joined on the channel already
3216 in JOIN command. Affected file lib/silcclient/command.c.
3218 * Fixed the JOIN command reply to check whether the channel
3219 already exists. Affected file lib/silcclient/command_reply.c.
3221 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Added silc_ske_status_string to map the SKE error numbers
3224 to readable strings. The affected files are
3225 lib/silcske/silcske[_status].[ch].
3227 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Do not show the private channels on the WHOIS channel list
3230 as it is not allowed by the protocol. The affected file is
3233 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Assure that the packet length digged from the actual packet
3236 is something sensible in the silc_packet_decrypt_rest_special
3237 in lib/silccrypt/silcpacket.c.
3239 * Free and NULL the allocated pointer in silc_hmac_alloc if
3240 the HMAC allocation fails. The affected file is
3241 lib/silccrypt/silchmac.c.
3243 * Print the selected security properties to the log files in
3244 the server. Affected file silcd/protocol.c.
3246 * Add SKE's reference counter even if calling the completion
3247 callback manually. Otherwise it goes negative, although it
3248 does not cause any problems. The affected file is
3249 lib/silcske/silcske.c.
3251 * Remove the client entry with short timeout after giving the
3252 KILL command. Affected file lib/silcclient/command.c.
3254 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3255 case all found clients are already disconnected (WHOWAS would
3256 found them) in the server. Affected file silcd/command.c.
3258 * Update the last_receive (time of last data received) to be
3259 updated only when received private or channel message so that
3260 the idle time showed in WHOIS makes more sense.
3262 * Added boolean field `valid' in to the SilcClientEntry in the
3263 client library to indicate whether the entry is valid or not.
3264 This fixes the nickname change bug on channel when changing
3265 the nickname to be same than the old (like nick to Nick) the
3266 nickname formatter doesn't set the new nick anymore to Nick@host.
3267 Affected file lib/silcclient/idlist.[ch].
3269 * Now actually fixed the nickname changing on disconnection.
3270 Added new function silc_change_nick to the Irssi SILC Client.
3271 Affected file irssi/src/silc/core/client_ops.c,
3272 irssi/src/silc/core/silc-nicklist.[ch].
3274 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Check that the public key exists in the GETKEY command before
3277 trying to encode it. Affected file silcd/command.c.
3279 * Print some notifications on received public keys with GETKEY
3280 command in the Irssi SILC Client. Affected files are
3281 irssi/src/fe-common/silc/module-formats.[ch],
3282 irssi/src/silc/core/client_ops.c.
3284 * Use IDENTIFY command to resolve the server information in the
3285 GETKEY command instead of INFO command. Affected file
3286 lib/silcclient/command.c.
3288 * All command reply functions in the client library now calls
3289 the pending command reply callbacks even if an error has
3290 occurred. The server has done this a long time and now it was
3291 time to move the client library to this as well. Now all
3292 errors can be delivered back to the pending command reply
3293 callbacks if necessary. Affected files are
3294 lib/silcclient/command[_reply].[ch].
3296 * Change the nickname on disconnection back to the username
3297 because in reconnect the server will enforce it to it anyway.
3298 Affected file irssi/src/silc/core/silc-servers.c.
3300 * Fixed a config file parsing bug in the Irssi SILC client.
3301 Affected file irssi/src/silc/core/clientconfig.c.
3303 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * When printing the channel mode on JOIN, verify that the
3306 channel key and channel's HMAC are valid. Affected file
3307 irssi/src/silc/core/client_ops.c.
3309 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3312 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3313 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3315 * Removed channel key rekey task deleting from the function
3316 silc_server_save_channel_key. Affected file silcd/server.c.
3317 Added explicit timeout task context instead that is used to
3318 delete the task if we are registering a new task before the
3319 new task has elapsed.
3321 * When channel key rekey occurs the client library now saves
3322 the old channel key for a short period of time (10 seconds) and
3323 is able to use it in case some is still sending channel
3324 messages encrypted with the old key after the rekey. Affected
3325 file lib/silcclient/[idlist.h|client_channel.c].
3327 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Added check to the silc_server_new_id_real to not accept
3330 new ID if it is the sender's own ID. Affected file is
3331 silcd/packet_receive.c.
3333 * Assure that we do not announce ourself or the one we've
3334 sending our announcements when we're router and are announcing
3335 servers to our primary router. Affected file silcd/server.c.
3337 * Fixed silc_server_command_identify_check_client to assemble
3338 correct WHOIS packet. It send corrupted WHOIS packet and
3339 caused problem with router to router connections. Affected
3340 file silcd/command.c.
3342 Fixed also silc_server_command_whois_check the same way
3343 as for the IDENTIFY command.
3345 * Added new SilcIDListStatus to the server in the SilcIDListData
3346 structure. The status now includes the current status of
3347 the entry (like registered, resolved etc.). Affected file
3348 silcd/idlist.[ch]. Defined a bunch of different status types
3349 as well. This replaced the old boolean registered field as well.
3351 Added resolve_cmd_ident field to the SilcClientEntry structure
3352 too so that if the entry is for example being resolved so
3353 another command may attach to the same pending command reply
3354 without requiring to resolve the same entry again. This concept
3355 should optimize the WHOIS and the IDENTIFY resolving under
3356 heavy load by taking away unnecessary resolving for entries
3357 that are being resolved already.
3359 Added support for adding multiple pending commands for one
3360 command idenfier. Affected file silcd/command[_reply].[ch].
3362 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3363 before deleting the data. Otherwise the hash table will have
3364 freed data in comparison functions. Affected file is
3365 silcd/command_reply.c.
3367 * Fixed silc_idlist_replace_client_id to add the new entry to
3368 the cache with NULL nickname. Otherwise there will be invalid
3369 memory as the nickname after the nickname is freed. Affected
3370 file silcd/packet_receive.c.
3372 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3373 saved into wrong slots because the previous number of entries
3374 was not taken into account. Affected file silcd/idlist.c.
3375 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3377 * If we are router and we receive JOIN notify to a channel that
3378 does not have any users then notified client is marked as the
3379 channel founder, as it is it. The affected file is
3380 silcd/packet_receive.c
3382 * Added to the extended hash table API's table_del_*ext functions
3383 the destructor as argument too, so that the caller can decide
3384 which destructor to use or whether to use destructor at all.
3385 Affected file lib/silcutil/silchashtable.[ch].
3387 * Fixed ID Cache purging. It actually deleted the entries from
3388 the hash table after the data was freed. The hash table ended
3389 up comparing freed memory. The affected file is
3390 lib/silccore/silcidcache.c.
3392 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3394 * Fixed Irssi SILC client's KILL command's HELP syntax.
3396 * The USERS command now resolves the detailed user information
3397 if the userinfo field is missing. Affected file is
3398 lib/silcclient/command_reply.c.
3400 * Do not print error in silc_file_read if the read file does
3401 not exist. Just silently return NULL. Affected file is
3402 lib/silcutil/silcutil.c.
3404 * Fixed the silc_log_output to not wine about NULL filename
3405 and to not create some bogus " " filename. Affected file is
3406 lib/silcutil/silclog.c.
3408 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Fixed various printing bugs on the user interface in the
3411 Irssi SILC Client. Minor changes that were forgotten from
3414 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Fixed the configure.in.pre and the compilation and distribution
3417 environment to support the new autoconf 2.52. That version is
3418 now required to compile the CVS trunk.
3420 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3423 to generally parse user@fqdn format strings. Affected file
3424 lib/silcutil/silcutil.c.
3426 * Added nickname_format and nickname_force_format fields to the
3427 SilcClientParams structure. The first one defines the format
3428 for the nicknames that the library will enforce if the receives
3429 multiple same nicknames. The second one is boolean value and
3430 can be used to force the library to always enforce the format
3431 to the nicknames regardles whether there are multiple nicknames
3432 or not. This configurable formatting was employed to flexibly
3433 support accessing multiple nicknames from the user interface.
3434 The userinterface can now set the nicknames to what ever format
3435 they prefer. Affected file lib/silcclient/silcapi.h.
3437 Added function silc_client_nickname_format to the file
3438 lib/silcclient/idlist.c. It performs the nickname formatting.
3440 Added new field `hostname´ to the SilcClientEntry context.
3441 It holds the hostname of the client. Affected file is
3442 lib/silcclient/idlist.h.
3444 * Irssi SILC Client sets the nicknames in nick@hostn format.
3445 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3446 irssi/src/silc/core/silc-core.c.
3448 The WHOIS printing now also shows both the real nickname and
3449 the formatted nickname so that user knows how to access the
3450 user if there are multiple same nicknames cached. Affected
3451 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3452 printing formatting too to take the hostname now as a separate
3453 argument. The Affected file is
3454 irssi/src/fe-common/silc/modules-formats.[ch].
3456 * Changed the silc_client_get_clients_local to accept the formatted
3457 nickname as argument. It accepts the real nickname too but the
3458 formatted nickname can be used to find the true entry from
3459 multiple entries. Affected file lib/silcclient/silcapi.h and
3460 lib/silcclient/idlist.c.
3462 * Added nickname_format_parse field to the SilcClientParams.
3463 It is a callback function provided by the application to parse
3464 the nickname out of the formatted nickname string. The library
3465 calls it to get the nickname from the formatted string. Since
3466 the application generally knows better the format of the nickname
3467 string it parses it instead of the library, even though library
3468 encodes the formatted string. If the callback function is not
3469 provided then the library will use the string as is. The
3470 affected file is lib/silcclient/silcapi.h.
3472 * All the nickname strings passed to the client library in
3473 commands are now expected to be formatted nickname strings.
3474 If the command does not support the formatted nickname string
3475 it will assume that the sent string is the actual nickname.
3476 Affected file lib/silcclient/command.c.
3478 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Added public key authentication support to OPER and SILCOPER
3481 commands in the client library. Affected file is
3482 lib/silcclient/command.c.
3484 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Changed the get_auth_methdod client operation to be asynchronous.
3487 It can be async if the application resolves the authentication
3488 method from the server during the negotiation. Added new
3489 SilcGetAuthMeth completion callback that the application will
3490 call after resolving the authentication method.
3492 Added function silc_client_request_authentication_method that
3493 the application can use to resolve the authentication method
3494 from the server. Added also SilcConnectionAuthRequest callback
3495 that the library will call after the server has replied. The
3496 application can call this function if it does not know the
3497 current authentication method.
3499 Affected files are lib/silcclient/client.c and
3500 lib/silcclient/silcapi.h.
3502 * The Irssi SILC client now automatically resolves the authentication
3503 method incase any configuration information is not present (and
3504 currently there never is). The affected file is
3505 irssi/src/silc/core/client_ops.c.
3507 * Fixed public key authentication from the client library.
3508 Affected file lib/silcclient/protocol.c. Changed also the
3509 protocol specification about the public key authentication in
3510 the connection authentication protocol. The actual data to be
3511 signed is now computed with a hash function before signing.
3513 * Fixed the public key authentication from the server as well.
3514 Affected file silcd/protocol.c.
3516 * Removed the mlock()'s from the memory allocation routines.
3517 Affected file lib/silcutil/silcmemory.c. The ./configure does
3518 not check anymore for the mlock(). Affected file is
3521 * Fixed USERS command in server to allow the execution of the
3522 command for private and secret channels if the client sending
3523 the command is on the channel. Affected file silcd/command.c.
3525 * Fixed silc_client_get_clients_local to return the clients
3526 count correctly. It could return wrong value. Affected file
3527 lib/silcclient/idlist.c.
3529 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3532 types. The assembler optimizations seemed not to like 64-bit
3533 data types. The assmebler optimizations thus are now enabled
3534 also for BSD systems as opposed to only enable them for Linux.
3536 * Do not check for threads at all on BSD systems. Affected
3537 file configure.in.pre.
3539 * Removed -n and -h options from the Irssi SILC Client since
3540 they are not used in silc.
3542 * Fixed the prime generation to assure that the first digit
3543 of the generated random number is not zero since our conversion
3544 routines does not like number strings that starts with zero
3545 digit. If zero digit is seen the random number is regenerated.
3546 This caused some corrupted RSA keys when the zero first digit
3547 was met. Affected file lib/silcmath/silcprimegen.c.
3549 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Fixed WIN32 configuration in the ./configure script.
3552 Fixed to include xti.h on environments that has it.
3553 Patches by Carsten Ilchmann and andrew.
3555 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Changed the silc_id_create_client_id to be collision
3558 resistant. It is now assured that there cannot be created
3559 two same client ID's. I suspect that some weird bugs in
3560 the server were actually caused by duplicate Client IDs.
3561 Affected file silcd/serverid.[ch]. A router receiving
3562 new ID now also assures and informs the sending server
3563 if the ID caused collision.
3565 * Changed the silc_id_create_channel_id to also assure that
3566 there are no collisions.
3568 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Statement about ignoring the Mutual Authentication flag when
3571 performing rekey with PFS was a bit misleading. It is ignored
3572 if it was set in the initial negotiation, it cannot be even
3573 set in the rekey. Fixed in the ke-auth draft. Started the
3574 new versions of the protocol drafts in the doc/.
3576 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Fixed a bug in silc_client_command_identify_save when saving
3579 new channel information. The channel name was no duplicated
3580 and caused crash on exit. Affected file is
3581 lib/silcclient/command_reply.c.
3583 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Fixed the getkey command handling in the server. Send just
3586 empty OK reply to the sender if the key could not be fetched
3587 (but everything else was ok, like the key just was not available).
3588 Changed the public key parameter to optional in the protocol
3589 specs so that empty OK reply can be sent. Affected file
3592 Added a message to Irssi SILC client to tell to user if the
3593 server did not return a public key.
3595 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3597 * Fixed a channel key regeneration bug. It registered new
3598 timeout tasks exponentially until all system resources were
3599 used. Affected file silcd/server.c.
3601 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Added the SILC Document generator to the scripts/silcdoc.
3604 It can be used to generate the Toolkit Reference Manual out
3605 of the source tree. Internally it will also use the RoboDoc
3606 generator now imported in util/robodoc.
3608 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Added couple of return's in rekey protocol if error orccurred
3611 during the protocol. The execution must be terminated.
3612 Affected file silcd/protocol.c. Also, terminate the protocol
3613 always with timeout.
3615 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * The client's Client ID was created initally from the wrong
3618 nickname (it could have been in format nick@host) in the
3619 silc_server_new_client. Affected file silcd/packet_receive.c
3621 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Added some SILC_LOG_ERROR's to various error conditions
3624 if client could not be added to ID cache. Affected files
3625 silcd/packet_receive.c and silcd/server.c.
3627 * When client's sock->user_data is freed, NULL also the
3628 client->router and client->connection pointers. Added check
3629 for these pointers being NULL to various places around the
3630 code. Affected file silcd/server.c.
3632 * Added client->data.registered == TRUE checks to various
3633 places around the code to assure that unregistered client's
3634 are not handled when it is not allowed. Affected file
3637 * Added `bool registered' fields to all
3638 silc_idlist_[server|client]_get_* routines to indicate whether
3639 the fetched client needs to be registered or not. Affected
3640 file silcd/idlist.[ch].
3642 * Add your own entry as registered to the ID cache in the
3643 server. Affected file server.c.
3645 * Fixed a bug in silc_server_new_server. The SilcServer was
3646 set as the new server's context instead of SilcServerEntry.
3647 This naturally caused some weird bugs.
3649 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Do not delete the channel rekey task when adding it
3652 for in silc_server_create_channel_key.
3654 * Changed the silc_server_create_channel_key to return
3655 TRUE or FALSE to indicate the success of the channel key
3658 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3660 * Fixed MSVC++ project files and added missing files to

3669 * Fixed buffer overflow from Irssi SILC Client. Affected
3670 file irssi/src/fe-common/core/themes.c.
3672 * Fixed double free in client library in the file
3673 lib/silcclient/client.c when disconnecting from server.
3675 * Applied double free patch from cras to Irssi SILC client.
3676 Affected files irssi/src/core/[modules/expandos].c
3678 * Fixed the disconnection handling to Irssi SILC Client.
3679 The application must call silc_client_close_connection
3680 in ops->connect client operation in case of failure of
3681 the connection. Affected file is
3682 irssi/src/silc/core/client_ops.c.
3684 * Do not set sock->protocol to NULL in the function
3685 silc_client_close_connection after executing the protocol's
3686 final callback since the sock might not be valid anymore.
3687 Affected file lib/silcclient/client.c.
3689 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Do not enable SILC_THREADS if the linking with libpthread
3692 did not happen. Affected file configure.in.pre.
3694 * Added notion to protocol specification that server must
3695 verify the sent authentication payload with CMODE when
3696 setting the channel founder key. Implemented it to the
3697 server. Affected file silcd/command.c.
3699 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Added _EXTRA_DIST SILC distribution variable to the
3702 distributions file. It is used to conditionally add extra
3703 files or directories to the specific distribution. Affected
3704 files ./prepare, Makefile.am.pre and distributions.
3706 Removed the `_' from the start of the distribution names.
3709 * Added README.WIN32 for instructions to compile the Toolkit
3712 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Fixed a double free in disconnection in the server. Affected
3715 file is silcd/server.c.
3717 * Fixed the lib/silcske/groups.c to work now also with GMP
3718 MP library. The string conversion did not work when using
3719 specific base and the base is indicated in the string as well.
3721 * Created win32/ directory which now includes MSVC++ specific
3722 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3723 It will appear only in the toolkit distribution
3725 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Changed the key material distribution function in case when
3728 the hash output is too short. The data is now concatenated
3729 a bit differently than it used to. Made the change to the
3730 SKE protocol specification.
3732 * Added better GMP detection to configure.in.pre. A patch
3735 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3737 * Fixed a minor bug in SKE that might cause some problem on
3738 some platforms. Affected file lib/silcske/silcske.c.
3740 * Added the cookie checking for initiator in the SKE. It checks
3741 that the responder returns the sent cookie unmodified. The
3742 affected file is lib/silcske/silcske.c. Added new SKE
3743 error type INVALID_COOKIE that can be sent during the
3744 negotiation. Fixed some memory leaks as well.
3746 * Added the "invalid cookie" error message to Irssi SILC client's
3749 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Added `task_max' field to the SilcClientParams to indicate
3752 the maximum tasks the scheduler can handle. If set to zero,
3753 default values are used. Affected file lib/silcclient/silcapi.h.
3755 * Fixed memory leaks in silc_client_close_connection. Affected
3756 file lib/silcclient/client.c.
3758 * Added silc_client_del_client_entry to client library to free
3759 all memory of given client entry. Affected file is
3760 lib/silcclient/idlist.[ch].
3762 * Added new functions silc_client_del_channel and
3763 silc_client_del_server to delete channel and server entries.
3764 Affected file lib/silcclient/[silcapi.h/idlist.c].
3766 * Removed silc_client_del_client_by_id from silcapi.h.
3768 * Fixed the INFO command to return the server's own info
3769 correctly when querying by Server ID. Affected file is
3772 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3774 * Removed the non-blocking settings in WIN32 code in the
3775 silc_sock_[read/write] and added SleepEx instead. Affected
3776 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3777 of input data is now checked with FIONREAD and ioctlsocket.
3779 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3781 * Call silc_schedule_task_del_by_context in the
3782 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3783 Affected file lib/silccore/silcprotocol.c.
3785 * Call silc_protocol_cancel for active protocols in the
3786 silc_server_close_connection if the funtion
3787 silc_server_free_sock_user_data has not been called.
3788 Affected file silcd/server.c.
3790 * Generic tasks cannot be deleted using the del_by_fd
3791 task deleting function since generic tasks does not match
3792 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3794 * Added a notion to SILCOPER help file that the SILCOPER works
3795 only on router server, not on normal server.
3797 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3799 * Added for WIN32 support for the new scheduler as well.
3800 Affected file lib/silcutil/win32/silcwin32schedule.c.
3802 * Fixed the SHA1 implementation to work on various platforms.
3804 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3807 API. It is part of the scheduler now. Everything else is
3808 as previously but some functions has changed their names.
3809 Checkout the lib/silcutil/silcschedule.h for the interface.
3810 Updated all applications to use the new interface. Affected
3811 files are lib/silcutil/silcschedule.[ch].
3813 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Found a bug in the SKE implementation. The HASH value,
3816 specified by the protocol, was not computed correctly. The
3817 public key of the responder was not added to the computation
3818 even though it is mandatory. Affected file lib/silcske/silcske.c.
3819 This unfortunately causes incompatibilities with older
3820 clients and servers.
3822 * Added WIN32 specific network init and uninit functions:
3823 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3824 the Winsock2. Affected file lib/silcutil/silcnet.h and
3825 lib/silcutil/win32/silcwin32net.c.
3827 * Set the socket always to nonblocking mode on WIN32 after
3828 reading data or writing data. Affected file is
3829 lib/silcutil/win32/silcwin32sockconn.c.
3831 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Fixed various compilation problems under WIN32. Affected
3834 files lib/silcutil/win32/silcwin32thread.c and
3835 lib/silcutil/win32/silcwin32schedule.c.
3837 * Removed all _internal.h #includes from public header
3838 files. Internal headers must never be included from
3841 Removed also the lib/silcske/payload_internal.h file.
3843 * All include files that may be needed (public and some others
3844 included by the public headers) by application developers are
3845 now copied to the ./includes directory. It does not copy any
3846 internal headers. Affected file Makefile.defines.pre and all
3847 Makefile.am's under lib/ and subdirs.
3849 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3851 * Do not change the ~/.silc directory's permissions automatically.
3852 Affected file irssi/src/silc/core/clientutil.c.
3854 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Do not cancel the protocol in silc_server_close_connection
3857 it might cause recursion. Now cancelled in the function
3858 silc_server_free_sock_user_data. Affected file silcd/server.c.
3860 * Fixed the silc_server_remove_clients_by_server to regenerate
3861 the channel keys correctly finally. Added also new function
3862 silc_server_remove_clients_channels to actually do it.
3863 Affected file silcd/server.c.
3865 * Fixed the silc_server_new_channel to not crash by giving
3866 wrong router to the new channel. Affected file is
3867 silcd/packet_receive.c.
3869 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3872 which is given as argument to the silc_client_alloc now.
3873 It can be used to configure the client and set various parameters
3874 that affect the function of the client.
3876 * The USERS command in server did not check whether the channel
3877 is private or secret. Affected file silcd/command.c.
3879 * Added new argument to the USERS command in protocol specification.
3880 The USERS command now can take the channel name as argument
3881 as well. Added support for this in client and server and
3882 updated the protocol specs.
3884 * Completed the GETKEY command in client. It can be now used
3885 to fetch also servers public key not only some clients.
3886 Affected files lib/silcclient/command[_reply].c.
3888 * Added silc_client_get_server to return server entry by the
3889 server name. Affected files lib/silcclient/silcapi.h and
3892 * Redefined the IDENTIFY command in protocol specification to be
3893 more generic. It now can be used to query information about
3894 any entity in the SILC Network, including clients, servers and
3895 channels. The query may be based either the entity's name
3896 or the ID. Added support for this in both client and server.
3898 Affected files silcd/command.c and lib/silcclient/command.c
3899 and command_reply.c.
3901 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3902 the _from_client and _from_server functions. Affected file
3905 * Added silc_client_get_channel_by_id_resolve to the file
3906 lib/silcclient/silcapi.h to resolve channel information by
3907 its ID. Added also silc_client_get_channel_by_id that
3908 does not resolve it from the server.
3910 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3912 * Added SilcServerEntry context into the client library
3913 to represent one server. The INFO command now allocates
3914 these to save the resolved server info. For now on the
3915 client library will also keep information about servers,
3916 connected and resolved with INFO.
3918 The INFO command now allocates the SilcServerEntry context
3919 and saves the server info there. The COMMAND_REPLY in
3920 the INFO now returns the parameters to application in
3921 same order as defined in the protocol specification.
3923 The entries are cached in the client->server_cache.
3925 * The INFO command is now issued after received the Client ID
3926 from the server. Affected file lib/silcclient/client.c.
3928 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3929 to the application as the mode changer might be server.
3930 It is guaranteed that NULL is not returned anymore to the
3931 application. Affected file lib/silcclient/client_notify.c.
3933 The ID Type is now also passed to the application so that
3934 it can check whether the returned entry is SilcClientEntry
3937 Added new function silc_client_get_server_by_id to return
3938 the server entry by ID. Affected files are the
3939 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3941 * Do not create the channel in the Irssi SILC Client when issuing
3942 the JOIN command but when received the sucessful JOIN command
3943 reply. Otherwise the channel might get created even though we
3944 could not join it. The Affected file is
3945 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3947 * Fixed a channel joining bug in router. The router must also
3948 check the channel modes, invite and ban lists etc. when serving
3949 the JOIN command sent by normal server. Affected file is
3950 silcd/command.c. The router now resolves the client's
3951 information from the server who sent the JOIN command if it
3952 does not know it, and processes the JOIN command only after
3955 * Changed the SilcCommandCb to take new argument; void *context2.
3956 Affected file lib/silccore/silccommand.h
3958 The second argument in the command callbacks in the server now
3959 includes the SilcServerCommandReplyContext if the command was
3960 called as pending command callback from the command reply.
3961 Otherwise it is NULL. When called as pending the status of the
3962 command reply will be checked and if it was erronous the
3963 error will be sent to the original sender of the command.
3964 This way the client always receives the error messages even
3965 though the server was actually the one who received the error
3966 when it resent the command to router, for example. Affected
3967 files silcd/command[_reply].[ch].
3969 * Fixed sending WHOWAS command's error message to client if
3970 the requested client could not be found. It was missing.
3973 * Changed the CMODE and CUMODE commands reply arguments in the
3974 protocol specification. The Channel ID is now sent in both
3975 of the commands to identify the channel. Implemented this
3976 new feature to the client and server. Affected files
3977 lib/silcclient/command_reply.c and silcd/command.c.
3979 * Made better checks for invite and ban lists in the JOIN
3980 command in server. Affected file silcd/command.c.
3982 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * The server now performs the incoming host IP/DNS lookup
3985 using the silc_socket_host_lookup and thus does not block
3986 the server anymore. Affected file silcd/server.c.
3988 * Completed the multi-thread support for SILC Scheduler in
3989 the lib/silcutil/silcschedule.c.
3991 * Fixed the configure.in.pre to detect the pthread correctly
3994 * Fixed a deadlock in silc_task_queue_wakeup in the file
3995 lib/silcutil/silctask.c.
3997 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3999 * Added new function silc_schedule_wakeup that is used in
4000 multi-threaded environment to wakeup the main thread's
4001 schduler. It needs to be used when a thread adds a new task
4002 or removes a task from task queues. After waking up, the
4003 scheduler will detect the task queue changes. If threads
4004 support is not compiled in this function has no effect.
4005 Implemented the wakeup mechanism to both Unix and WIN32
4006 systems. Affected files are lib/silcutil/silcschedule.[ch],
4007 lib/silcutil/unix/silcunixschedule.c and the
4008 lib/silcutil/win32/silcwin32schedule.c.
4010 * Added new function silc_task_queue_wakeup to wakeup the
4011 scheduler by the specified task queue. Affected file
4012 lib/silcutil/silctask.[ch].
4014 * The silc_socket_host_lookup_start now wakes up the scheduler
4015 after adding the timeout task. Affected file is
4016 lib/silcutil/silcsockconn.c.
4018 * The silc_socket_host_lookup is synchronous now if the threads
4019 support is not compiled in. However, the callback is still
4020 called asyncronously through the scheduler, anyway. Affected
4021 file lib/silcutil/silcsockconn.c.
4023 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4025 * Added new function silc_socket_host_lookup to perform
4026 asynchronous IP and FQDN lookups for the socket connection.
4027 Affected files lib/silcutil/silcsockconn.[ch].
4029 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4031 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4032 that may or may not compile the mutex support in.
4034 Changed the silc_mutex_alloc interface. It allocates the
4035 mutex now to the sent pointer and returns TRUE or FALSE.
4037 Affected file lib/silcutil/silcmutex.h.
4039 * Wrote the SILC Task Queue interface to support multi-threads.
4040 Affected file lib/silcutil/silctask.[ch].
4042 * Wrote the SILC Scheduler to support multi-threads. Affected
4043 file lib/silcutil/silcschedule.c.
4045 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4047 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4048 in lib/silcutil/win32/.
4050 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Defined SILC Mutex API and SILC Thread API and implemented
4053 them for Unix. Affected files are
4054 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4055 lib/silcutil/unix/silcunixmutex.c and
4056 lib/silcutil/unix/silcunixthread.c.
4058 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * Fixed the silc_server_remove_clients_by_server's channel
4061 key re-generation. The hash table handling was incorrect
4062 and would not work with many channels. Affected file is
4065 * Fixed some memory leaks around the server code.
4067 * Rewrote the silc_server_get_users_on_channel to support IPv6
4068 based Client ID's. Affected file silcd/server.c.
4070 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4071 specification. However, a separate document must be written
4072 to define the detailed signing procedure and the payload
4073 associated with the flag. Defined the flag to the
4074 lib/silccore/silcchannel.h as well.
4076 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Changed the dynamic tables to static size tables in the
4079 lib/silccrypt/silchmac.c.
4081 * Removed GCC dependencies from the code. A patch by cras.
4083 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4085 * Do not show the error "Error receiving packet bla bla"
4086 in server if it really was not an error (-2 means that reading
4087 is pending). Affected file silcd/server.c.
4089 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Fixed a possible crash in silc_server_remove_clients_by_server
4092 in silcd/server.c. Fixed there also some memory leaks.
4094 * Fixed the silc_idlist_replace_client_id. It could replace
4095 wrong key in the hash table. Affected file silcd/idlist.c.
4097 * Do not check whether there are global users on the channel
4098 if the channel->global_users is FALSE. Affected functions
4099 silc_server_remove_from_one_channel and
4100 silc_server_remove_from_channels in silcd/server.c. Also,
4101 do not check if the removed client is local as we can be
4102 sure that global client was not removed from the channel
4103 and checking for global users is not needed.
4105 * The silc_server_remove_clients_by_server now re-generates
4106 the channel keys correctly for those channels that had
4107 clients removed from them. Affected file silcd/server.c.
4109 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4111 * Found the reason of random crashes in the server. We weren't
4112 ignoring the SIGPIPE signal (which can be sent in write())
4113 and it crashed the server. Affected file silcd/silcd.c.
4115 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Assure that sock->user_data is not NULL in the function
4118 silc_server_packet_send in silcd/packet_send.c.
4120 * Disconnect the remote connection if it could not be added
4121 to any ID lists in the server. The affected file is
4124 * Check in silc_server_packet_send[_real/dest] that the
4125 socket is not disconnecting and ignore the data if it is.
4126 Affected file silcd/packet_send.c.
4128 * Define inline to __inline on native WIN32 compilation.
4129 Affected file includes/silcwin32.h.
4131 * Added some explicit type casts for inline code since MSVC
4132 require them. Affected files lib/silcutil/silcbuffer.h,
4133 lib/trq/silcdlist.h and lib/trq/silclist.h.
4135 * Print warning in log files from now on if the packet
4136 decryption fails. Affected file silcd/server.c.
4138 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Changed the `say' client operation's interface to accept
4141 new `type' argument to indicate the type of the message sent
4142 by the library. The application may filter the library's
4143 messages according the type. The affected file is the
4144 lib/silcclient/silcapi.h.
4146 * Added two new functions to lib/silcclient/silcapi.h:
4147 silc_client_del_client and silc_client_del_client_by_id.
4148 Affected file lib/silcclient/idlist.c.
4150 * Moved the clientincludes.h from includes/ to silc/ and
4151 serverincludes.h from includes/ to silcd/.
4153 * The modes for the CMODE and CUMODE are now passed as
4154 uint32 for application with COMMAND_REPLY. The affected
4155 file is lib/silcclient/command_reply.c.
4157 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4159 * /WHOIS without arguments shows client's own information.
4160 Affected file lib/silcclient/command.c.
4162 * Changed PING to not accept any arguments. The specs
4163 says that client can ping only the connected server so
4164 requiring an argument is not needed. Affected file is
4165 lib/silcclient/command.c.

4169 * Fixed a fatal bug in private message sending and reception
4170 encryption and decryption when using private message keys.
4171 The implementation was incorrect and did not follow the
4172 specification. It causd that some of the message were
4173 lost since it did not use the sending and receiving keys
4174 as the protocol suggests. This has been fixed and will cause
4175 incompatibilities with older clients when sending private
4176 message encrypted with private message keys. Affected files
4177 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4178 and various other in Irssi SILC Client.
4180 Added `responder' boolean argument to the functions
4181 silc_client_add_private_message_key[_ske] to indicate when
4182 the key is added as responder or initiator of the key
4185 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4187 * Removed the silc_ske_check_version function and created
4188 a SilcSKECheckVersion callback. Added also a function
4189 silc_ske_set_callbacks that is now used to set all SKE
4190 callbacks. The callback functions are not given to
4191 the SKE functions anymore, but this function is used to
4194 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4196 * Added `silc_version' argument to the silc_client_alloc
4197 to define the version of the application for the library.
4198 The library will use the version string to compare it
4199 against the remote host's (usually a server) version
4200 string. Affected file lib/silcclient/silcapi.h
4202 * Added the KE protocol context to Key Agreement context
4203 in client library so that we can abort the SKE if it
4204 is in process when we get timeout. Affected file is
4205 lib/silcclient/client_keyagr.c.
4207 * Do not resolve the client ID forever if it returns in the
4208 first time that such client does not exist. This was done
4209 for example with private message. Affected file is
4210 lib/silcclient/client_prvmsg.c.
4212 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4214 * Do not add regex.h for WIN32. The affected file
4215 includes/silcincludes.h.
4217 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4218 not work yet 100%. It generates the DLL's automatically
4219 when compiling with --with-win32 under cygwin.
4221 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4223 * lib/contrib/regex.c is not compiled on WIN32.
4225 * Added silc_net_get_socket_opt function to the
4226 lib/silcutil/silcnet.h.
4228 * Added includes/silcwin32.h for WIN32 specific includes
4231 * Do not use ptime structure or any of the posix process
4232 functions on WIN32 in lib/silccrypt/silrng.c.
4234 * Added silc_gettimeofday to provide generic function
4235 for struct timeval on all platforms. Added the function
4236 to lib/silcutil/silcutil.h.
4238 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4241 library as they clearly belong there. As a plus side we
4242 can make the actual socket connection routines platform
4245 Added also new generic function silc_socket_read and
4246 silc_socket_write (that used to be silc_packet_[read/write].
4247 The implementation of these are platform specific.
4249 * Added WIN32 specific routines of silc_socket_[read/write]
4250 to lib/silcutil/win32/silcwin32sockconn.c.
4252 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Added preliminary support for native WIN32 compilation under
4255 cygwin (using the -mno-cygwin option for GCC) to the
4256 ./configure.in.pre. The --with-win32 now prepares the
4257 compilation for native WIN32.
4259 * Rewrote the SILC Scheduler interface in the file
4260 lib/silcutil/silcschedule.h. The scheduler is now context
4261 based and does not have anymore any global static scheduler.
4262 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4263 and created lib/silcutil/win32 directory for WIN32 based
4266 * Added Unix specific network routines to the
4267 lib/silcutil/unix/silcunixnet.c and the old
4268 lib/silcutil/silcnet.c includes now only generic routines.
4270 Added WIN32 specific network routines to the
4271 lib/silcutil/win32/silcwin32net.c.
4273 * Added Unix specific utility functions from the
4274 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4276 * Added WIN32 SILC Scheduler to the file
4277 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4280 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * Do not handle JOIN notify in the server if the target client
4283 is not registered (idata->registered == FALSE). The affected
4284 file is silcd/packet_receive.c.
4286 * Update the nickrec->founder in event_cumode in the Irssi SILC
4287 client. Affected file irssi/src/silc/core/silc-channels.c.
4289 * Fixed the CUMODE_CHANGE notify handling in the server when
4290 server and router are announcing their clients on channels.
4291 Now the mode changes are saved and notified correctly. The
4292 affected file is /silcd/packet_receive.c.
4294 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4295 They really did not replace the cache entry in the ID Cache.
4296 Now they do that. Affected file silcd/idlist.c.
4298 * Fixed the KICK notify handling in the Irssi SILC client to
4299 update the channel records so that the kicked client does not
4300 appear to be on the channel. The affected file is
4301 irssi/src/silc/core/silc-channels.c.
4303 * Always update the conn->current_channel when executing command
4304 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4306 * Fixed the KILL notify handling in Irssi SILC client to remove
4307 the killed client on all channels.
4309 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Fixed the silc_parse_command_line to remove extra spaces
4312 from the start and end of the arguments. Affected file is
4313 lib/silcutil/silcutil.c.
4315 * Cancel and free any active protocol in the function
4316 silc_server_close_connection. Affected file silcd/server.c.
4318 * Cancel and free any active protocol in the function
4319 silc_client_close_connction. Affected file is
4320 lib/silcclient/client.c.
4322 * Do not execute the KILL command for clients that are in
4323 history (ie. they are not in the network). Affected file is
4326 * Fixed KILL notify handling, client does not crash anymore.
4327 Affected file irssi/src/silc/core/silc-channels.c.
4329 * Reduced the default packet buffer size from 2048 to 1024 in
4330 lib/silccore/silcpacket.c.
4332 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4333 counter to the SKE context that is incresed when the SKE library
4334 performs async operation outside the library. If the outside
4335 process frees the SKE context and FREED status will be set
4336 and the library will detect after the sync operation that the
4337 libary is freed. The affected files are
4338 lib/silcske/silcske[_status].[ch].
4340 * Resolve the client entry information in the function
4341 silc_client_channel_message to assure that NULL pointer is not
4342 passed as client entry to the application. */
4344 * Fixed the task timeout calculation to assure that there is
4345 never negative timeouts. The affected file is
4346 lib/silcutil/silcschedule.c.
4348 * Fixed the channel user mode notification sending in server.
4349 It was sent point-to-point to the router (or to server by router)
4350 but it needs to be destined to a channel. The routines now
4351 supports sending the channel user mode notifys to the channels
4352 when announcing clients and channels. Affected files are
4353 silcd/server.c and silcd/packet_receive.c.
4355 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4356 It did not actually replace the old channel entry in the cache.
4357 Affected file lib/silcclient/client_notify.c.
4359 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Fixed a possible crash in silc_packet_send_prepare. It now
4362 assures always that there is enough space in the buffer and
4363 at the tail area of the buffer (for MAC).
4365 Fixed the inbound buffer reallocation in silc_packet_read.
4366 It was old code and did not handle the reallocation correctly.
4369 The affected file is lib/silccore/silcpacket.c.
4371 * Fixed buffer overflow in silc_parse_nickname in the file
4372 lib/silcutil/silcutil.c.
4374 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * make install generates new server keys only if there is not
4379 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4382 Added check that if the NOREPLY is set then we will not send
4383 the away message. This avoids infinite loop of away messages
4384 if both clients are away. The affected file is
4385 lib/silcclient/client_prvmsg.c.
4387 * Fixed client crash if /NICK was given without arguments.
4388 Affected file lib/silcclient/command.c.
4390 * Server does not send the invite list in INVITE command back
4391 to the client if the list was not altered. Added this notion
4392 to the protocol spec as well. Affected file silcd/command.c.
4394 Fixed possible crash in INVITE command by checking the
4395 value of silc_server_get_client_route command.
4397 * Fixed the INVITE notify type handling. The arguments are now
4398 taken in correct order and client does not crash. The affected
4399 file is irssi/src/silc/core/silc-channels.c.
4401 Removed the "Inviting xxx to channel" message from the
4402 client library away and let the application handle it.
4403 Affected file lib/silcclient/command.c. Added that message
4404 to Irssi SILC client's message formats.
4406 * Fixed CMODE command crash in client. It now checks the
4407 amount of arguments correctly and does not crash. The affected
4408 file is lib/silcclient/command.c.
4410 * Do not create new channel automatically in silc_channels_join
4411 but check whether the channel by that name already exists.
4412 Affected file irssi/silc/core/silc-channels.c.
4414 * Do not send the SERVER_SIGNOFF to router if the disconnected
4415 entity was the router. Affected file silcd/server.c.
4417 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4418 SILC client as it was missing from there.
4420 Added the handling of the KICK notify to the Irssi SILC client
4421 as it was missing. Added "you have been kicked" message to
4422 Irssi SILC client's message modules formats.
4424 Added the handing of the KILL notify to the Irssi SILC client
4425 as it was missing. Added the kill message module formats
4428 The affected file is irssi/src/silc/core/silc-channels.c.
4430 * The router did not save the channel mode the server announced.
4431 Affected file silcd/packet_receive.c.
4433 * Fixed a possible crash in INFO command in server. If the
4434 server did not provide the server info it crashed. Affected
4435 file silcd/command.c.
4437 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Fixed the GETKEY command in the server to check also the
4440 global list. Otherwise the GETKEY would not work correctly
4441 in normal SILC server. Affected file silcd/command.c.
4443 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Fixed GETKEY crash, it crashed if the command did not succseed.
4447 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4450 is now real and not just an macro interface to GMP.
4452 Removed the entire GMP from the source tree and imported new
4453 NSS MPI library instead. Reason for removing GMP is that it is
4454 extremely large and compiles extremely slow. The NSS MPI
4455 is only a few files and compiles in less than 10 seconds.
4456 The speed is also about the same as GMP. The MPI is imported
4457 to lib/silcmath/mpi.
4459 If the system has GMP installed we will still use the GMP.
4460 If it is not then the NSS MPI will be compiled.
4462 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Merged a long nickname (127 characters long) crash bugfix from
4465 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4467 * Merged a freed memory reference bugfix from Irssi CVS tree.
4468 Affected file irssi/src/core/commands.c.
4470 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Added the server's public key sving and verification to the
4473 server when performing the SKE. This was missing and the
4474 remote server's (or router's) public key was accepted without
4475 checking whether we have it previously or trust it at all.
4476 Affected file silcd/protocol.c.
4478 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Check in the silc_server_timeout_remote if protocol is active
4481 and make sure that the protocol's final callback is called so
4482 that all memory if freed. Affected file silcd/server.c.
4484 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * silc_server_whois_send_reply crashed the server if the nickname
4487 was 127 characters long. Affected file silcd/command.c.
4489 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Added sanity check to the silc_server_new_client. If the hostname
4492 is provided inside username then check that the provided hostname
4493 really is the same as the resolved one. If the hostname was not
4494 resolved then check it from the public key. Affected file is
4495 silcd/packet_receive.c.
4497 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4498 if the server disconnected us and the connection is not valid
4499 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4501 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4502 the library to the lib/silcutil/silcutil.[ch].
4504 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Close log file after open. Affected file
4507 lib/silcutil/silclog.c.
4509 * Check whether sock == NULL in silc_client_send_packet and return
4510 if it is. Affected file lib/silcclient/silcclient.c.
4512 * Check rec->entry == NULL in the Irssi SILC Client before
4513 sending the channel message. Affecte file is
4514 irssi/src/silc/core/silc-servers.c.
4516 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Merged a splitted window bugfix from Irssi CVS tree. The
4519 affected file is irssi/src/fe-text/textbuffer-view.c.
4521 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4522 It did not print nickname.
4524 * Improved the distributions system a bit.
4526 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4529 irssi/src/fe-text/gui-window.c.
4531 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4532 to in-active server. The affected file is
4533 irssi/src/silc/core/client_ops.c.
4535 * Resolve the client in USERS command reply if the entry does
4536 not have username resolved. The affected file is
4537 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4538 command to WHOIS command to really resolve stuff. The USERS
4539 is not used any more in any critical section so WHOIS can
4540 be used even though it might be slower than IDENTIFY.
4542 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4545 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Changed the protocol API a bit more consistent in the
4548 lib/silccore/silcprotocol.[ch].
4550 * Changed the following headers to ROBODoc format:
4552 lib/silccore/silcpayload.h
4553 lib/silccore/silcprotocol.h
4554 lib/silccore/silcsockconn.h
4556 All core library headers are now formatted.
4558 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Fixed a bug in Irssi SILC client; do not show that you are
4561 server/router operator if you really are not. Affected file is
4562 irssi/src/silc/core/client_ops.c.
4564 * Renamed silc_command_free_payload to silc_command_payload_free.
4565 Affected file lib/silccore/silccommand.h
4567 * Added silcmath.h to include the prototoypes of various routines
4568 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4571 * Changed the following headers to ROBODoc format:
4573 lib/silccore/silcchannel.h
4574 lib/silccore/silccommand.h
4575 lib/silccore/silcid.h
4576 lib/silccore/silcidcache.h
4577 lib/silccore/silcmode.h
4578 lib/silccore/silcnotify.h
4579 lib/silccore/silcpacket.h
4580 lib/silcmath/silcmath.h
4582 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Added checking to the server code not to start the server if
4585 ciphers and stuff are not configured properly. Affected files
4586 silcd/serverconfig.[h] and silcd/server.c.
4588 * Changed the layout of the header files of the public interfaces
4589 in the SILC libraries. The new layout supports ROBODoc
4590 documentation tool (and some others) so that it is easy to create
4591 a library reference manual. All the other headers and source
4592 code must still follow the CodingStyle document. Also source
4593 code must not include these ROBODoc stuffs, only the headers.
4594 Furthermore, all public interface headers must now be named
4595 by using `silc' prefix, example: silcapi.h, silccipher.h.
4596 Some files were renamed due to this. All the other headers
4597 must not be used as public interfaces. I will update the
4598 CodingStyle document later. Changed following headers, so far:
4600 lib/silcclient/silcapi.h
4601 lib/silccore/silcauth.h
4602 lib/silccore/silcprivate.h
4603 lib/silccrypt/silcdh.h
4605 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Removed silc_client_packet_send_flush from the client library
4610 as it is not needed. Affected file lib/silcclient/client.[ch].
4612 * Added printing of message of unresolved authentication method
4613 to the Irssi SILC client. Added it to the module formats.
4614 Removed the same message from the client library.
4616 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Added new distribution feature, DISTLABEL. Every distribution
4619 can define own preprocessor label that can be used in the
4620 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4621 file distributions, acconfig.h.pre and prepare.
4623 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Added Makefile.defines_int to include the actual definitions
4626 for Makefile.defines.in. Tested the new distribution system,
4627 created distributions and tested installation.
4629 * Added AWAY message printing to the Irssi SILC client. Added
4630 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4632 * Added SCONNECT command to call the SILC's CONNECT command.
4633 Cannot use CONNECT directly since Irssi uses that internally.
4634 Affected file irssi/src/silc/core/silc-servers.c.
4636 Added ACTION local command. It is same as ME command but takes
4637 the channel as mandatory argument.
4639 Rewrote some of the Irssi's help files to suite for SILC
4642 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Added Makefile.defines[.in] that should for now on be included
4645 in all Makefile.am file in the source tree. That file includes
4646 all common compilation definitions for SILC source tree.
4648 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Minor changes to the ./prepare script to change the package
4651 name according the distribution name to the configure.in.
4653 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Created new distribution system. Added file `distributions'
4656 that defines all the distributions that can be created out of
4657 the SILC source tree. The ./prepare script now reads that
4658 file to determine how to prepare the distributions. The
4659 first argument to the ./prepare is the name of the distribution
4660 and second is the version of the distribution. If given
4661 without arguments it creates the default (toolkit) distribution
4662 with the default version (defined in ./prepare).
4664 All Makefile.am files that are subject to the distributions
4665 are now named as Makefile.am.pre. These are ./Makefile.am
4666 and lib/Makefile.am. Others may be changed later.
4668 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added invite list, ban list, some key management and connection
4671 error message printing to module formats in the Irssi SILC client.
4673 * Added new silc_client_set_away_message to set the away message
4674 that is back to the person who sent private message. The
4675 affected file lib/silcclient/silcapi.h and the
4676 lib/silcclient/client_prvmsg.c.
4678 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Fixed the private message sending in the Irssi SILC client,
4681 added local command KEY to the Irssi SILC client.
4683 Added key management and key agreement message formats to the
4684 irssi/src/fe-common/silc/module-formats.[ch].
4686 Added USERS (alias WHO) printing, server/router operator
4687 indication and LIST command printing to the module formats.
4689 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Fixed channel joining notify handling, cumode notify handling
4692 from Irssi SILC client.
4694 * Added SILC specific module-formats to the Irssi SILC client so
4695 that SILC specific message hilighting, colors etc is possible.
4696 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4698 Added channel mode, channel user mode, actions, notices,
4699 whois and whowas printing to the the module-formats.c.
4701 * Fixed a bug in channel deletion in the server. The channel
4702 is not left to the cache even if the channel founder auth mode
4703 is set when there are no users anymore on the channel. Affected
4704 file silcd/server.c.
4706 * The silc_net_localhost now resolves the entire hostname including
4707 the domain name. Affected file lib/silcutil/silcnet.c.
4709 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Changed the ask_passphrase client operation to be ascynchronous.
4712 It has now a completion callback and a context that the
4713 application must call after it has got the passphrase from
4714 the user. Affected files lib/silcclient/silcapi.h,
4715 lib/silcclient/protocol.c, lib/silcclient/command.c and
4718 Added SilcAskPassphrase callback that the application calls
4719 to deliver the passphrase to the library.
4721 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4722 The public key verification and especially a certificate
4723 verification is asynchronous procedure.
4725 Added new SILC_SKE_STATUS_PENDING status to indicate the
4726 request is pending and a callback will be called to finalize
4729 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4730 indicate that remote end did not send its public key (or
4731 certificate), even though we require it. Added check for this
4732 condition in the SKE. This was a security bug, now fixed.
4734 Defined new SilcSKEVerifyCbCompletion callback that is called
4735 when the verification process is completed.
4737 The affected files lib/silcske/silcske_status.h and
4738 lib/silcske/silcske.[ch].
4740 * Changed the verify_public_key client operation to be async
4741 as well. Defined SilcVerifyPublicKey callback that is used to
4742 indicate the success of the public key verification process.
4744 Changed the server and client to use the new async client
4747 * Changed the Irssi SILC client's internal scheduler to be called
4748 twice as many times as it used to be. As a result the client
4749 should be a bit faster now. Affected file is
4750 irssi/src/silc/core/silc-core.c.
4752 * Added support to Irssi SILC client of asynchronous public key
4753 verification and passphrase inquiry. Affected file is
4754 irssi/src/silc/core/silc-core.c.
4756 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Do not say "You have left channel %s" in client library.
4759 Moved it to the application. Affected files are
4760 lib/silcclient/command.c and silc/client_ops.c.
4762 * Fixed silc_client_get_clients. Command context was not
4763 duplicated and was freed memory in the callback. Affected
4764 file lib/silcclient/idlist.c.
4766 * Do not say "you are now talking..." on JOIN command in the
4767 client library. The appliation must handle it.
4769 * Do not say ".. changed topic to" in command reply in the
4770 client libary. The application must handle it.
4772 * Fixed TOPIC command sending in the client library.
4774 * Fixed a memory leak in silc_client_command_free in the file
4775 lib/silcclient/command.c.
4777 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Imported a modified version of Irssi client to the source tree.
4780 The Irssi will be used to create a new client called
4781 Irssi SILC. Imported to irssi/.
4783 Added silc_core_init_finish function to the Irssi. Affected
4784 file irssi/configure.in.
4786 A lot changes in the Makefile.ams around the irssi tree.
4788 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Do not rehash if the new size is same as the old size of the
4791 hash table, in the silc_hash_table_rehash*. The affected file
4792 lib/silcutil/silchashtable.c.
4794 * Replaced hash_table_del_by_context calls from the server
4795 (when channel->user_list and client->channels) to the
4796 hash_table_del as it is sufficient and faster.
4798 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Added silc_hash_table_list, silc_hash_table_get and the
4801 SilcHashTableList structure to provide an alternative way to
4802 traverse the hash table. The affected files are
4803 lib/silcutil/silchashtable.[ch].
4805 * Changed the server's idlist routines to use the hash table
4806 routines to optimize the code.
4808 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Replaced the client entry's `channel' list and channel entry's
4811 `user_list' list to hash tables for optimized lookup. Changed
4812 the code to use the hash table interface around the code.
4813 Affected file lib/silcd/idlist.[ch].
4815 * Added `auto_rehash' boolean argument to the function
4816 silc_hash_table_alloc to indicate whether the hash table should
4817 auto-rehash when it thinks is appropriate time. It will
4818 increase the hash table size if the there is twice as much
4819 entries in the table than the size of the table, and will
4820 decrease the size if there are twice as less entries than
4821 the size of the table.
4823 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4827 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * silc_idcache_purge_by_context deletes the entry now by context
4830 as it is supposed to do. Affected file lib/silccore/idcache.c.
4832 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4833 client is not anymore valid (WHOWAS givens the info) and not
4834 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4836 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Removed the `data' and `data_len' arguments from the ID Cache
4839 interfaces and added `name' argument. ID Cache does not handle
4840 anymore the binary data only a names associated with given ID.
4842 * When hashing a Client ID with silc_hash_id the entire ID is
4843 not hashed anymore, instead only the hash of the Client ID is
4844 hashed. This way we can access the Client ID from the cache
4845 with Client ID but with the hash of the ID (which is a hash of
4846 the nickname) as well without any difference in performance.
4848 Added also silc_idcache_find_by_id_one_ext to do one on one
4849 searching when we have the actual ID. Added also function
4850 silc_hash_client_id_compare. The affected files are
4851 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4853 * When hashing the name associated with a ID it is always done
4854 in lowercase. This way we can access the cache without worrying
4855 about case-sensitivity, even though, for example nicknames are
4858 * Fixed a bug in server with channel message sending. It put
4859 wrong ID type as destination ID. The affected file
4860 silcd/packet_send.c.
4862 * silc_idcache_del_by_context now deletes from all hash tables
4863 by context. Affected file lib/silccore/idcache.c.
4865 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Changed the client library to use the new ID Cache interface.
4868 Changes around the source tree.
4870 * Added silc_hash_table_rehash_ext to rehash with specific
4871 hash function. Affected file lib/silcutil/silchashtable.[ch].
4873 * Added silc_hash_string_compare to compare two strings in the
4874 hash table. Affected file lib/silcutil/silcutil.[ch].
4876 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Added new function silc_idcache_del_by_context into the
4879 lib/silccore/idcache.[ch].
4881 * Changed the server's ID list routines to use the new ID Cache
4882 interface. Changes around the source tree.
4884 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added silc_hash_table_del[_by_context]_ext functions in to the
4887 lib/silcutil/silchashtable.[ch].
4889 Removed silc_hash_table_find_all* routines and added new
4890 silc_hash_table_find_foreach to replace them.
4892 Added silc_hash_table_replace_ext function as extended
4893 replacing function. Separated the simple hash table interface
4894 from the extended hash table interface in the file
4895 lib/silcutil/silchashtable.h.
4897 * Fixed minor bugs and changed it to use some of the new
4898 hash table functions in lib/silccore/idcache.c
4900 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added new function silc_hash_table_find_all to return all keys
4903 in the hash table by the specified key. As the hash table is
4904 collision resistant it also makes it possible to have several
4905 duplicate keys in the hash table. This function may be used to
4906 find all of the keys from the hash.
4908 Added user_context arguments to the SilcHashFunction,
4909 SilcHashCompare and SilcHashDestructor to deliver user specified
4912 Added new fuctions silc_hash_table_find[_all]_ext to do
4913 extended lookup with specified hash and compare functions and
4914 specified user contexts.
4916 Added new function silc_hash_table_add_ext to add the key
4917 with specified hash function and user context.
4919 Added new function silc_hash_table_foreach to traverse all
4920 entrys in the hash table. Added SilcHashForeach callback
4923 Added new function silc_hash_table_del_by_context to delete
4924 the entry only if the context associated with the key matches.
4926 Affected files are lib/silcutil/silchashtable.[ch].
4928 * Removed silc_hash_[server/client/channel]_id and added just
4929 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4930 silc_hash_id_compare to compare two ID's using as the hash table
4931 comparison function. Added also silc_hash_data to hash
4932 binary data and silc_hash_data_compare to compare it.
4934 * Removed silc_idlist_find_client_by_hash as it is not needed
4935 anymore. Affected file silcd/idlist.[ch].
4937 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4938 to use internally the SilcHashTable. The new ID Cache is a lot
4939 faster than the old one. Some of the ID Cache interface was also
4940 rewritten and obsolete and stupid functions were removed.
4942 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Added entry_count field to the SilcHashTable to keep the number
4945 of the entries in the table. Implemented the function
4946 silc_hash_table_rehash. Added new function
4947 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4949 Fixed a minor bug in silc_hash_table_free.
4951 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4952 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4953 into the lib/silcutil/silcutil.[ch].
4955 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Implemented a collision resistant hash table into the
4958 lib/silcutil/silchashtable[ch]. See the header and the source
4959 for the SilcHashTable API.
4961 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Merged dotconf version 1.0.2 into lib/dotconf.
4965 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Do not compile anything in lib/silcsim/* if the SIM support
4968 is not enabled. The tree should now compile without problems
4971 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Compiled the SILC under cygwin. Compiled and tested briefly
4974 without problems. More tests needed. The SIMs didn't compile
4977 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4979 * Fixed possible crash in silc_get_username in the
4980 lib/silcutil/silcutil.c.
4982 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Fixed a va_arg in silc/client_ops.c.
4986 * Oops, RC5 routines were named AES and caused some problems
4987 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4989 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added new SilcIDIP structure into the lib/silccore/id.h and
4992 replaced the old `ip' fields from all SILC ID's to that type.
4993 This is a step towards IPv6 support.
4995 The silc_id_get_len takes now the ID as an extra argument.
4996 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4997 both IPv4 and IPv6 based ID's.
4999 The affected files are lib/silccore/id.[ch] and other files
5000 around the tree using these routines.
5002 * Removed the ID length arguments in server from various
5003 silc_server_send_notify_* routines -> they are not needed
5006 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Fixed memory leak in silc_encode_pem_file in the file
5009 lib/silcutil/silcutil.c.
5011 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Check minor version as well in the SKE. Affected files are
5014 silcd/protocol.c and lib/silcclient/protocol.c.
5016 * Added --identifier option to the server so that an identifier
5017 can be when creating the public key for the server. Affected
5018 file is silcd/silcd.c.
5020 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5021 lib/silccrypt/silcpkcs.c.
5023 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Register default ciphers and stuff when using -C option with
5026 the server. Affected file sildc/silcd.c.
5028 * Put back the servers public key filename format, it is better
5029 than the new one. For now, the client keys are saved with the
5030 new filename format. The affected file silc/client_ops.c.
5032 * Implemented the Cipher API for the rest of the ciphers that
5033 did not implement it or implemented it the wrong way.
5035 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Register default ciphers and stuff when using the -S option
5038 in the client. Affected file silc/silc.c. Same also when
5039 creating new key pair with -C option.
5041 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Fixed the silc_verify_public_key client operation function to
5044 save the public keys differently. The fingerprint is now
5045 used as filename and not the hostname. This way also the
5046 client keys are saved uniquely and not with hostnames. The
5047 affected file is silc/client_ops.c.
5049 * Trimmed the silc_hash_fingerprint function to remove extra
5050 whitespaces from the end of the fingerprint. The affected
5051 file is lib/silccrypt/silchash.c.
5055 * Added silc_cipher_register_default function to register all
5056 default ciphers. It can be used when configuration files
5057 does not exist and the application does not want any specific
5058 ciphers in any specific order.
5060 The SilcDList is now used as silc_cipher_list dynamically
5061 allocated cipher list. Removed the static list all together
5062 and now all ciphers must be allocated to the dynamic list.
5063 The silc_cipher_alloc routine was changed to check only the
5066 All silc_cipher_* routines that used to return int returns
5069 The affected files lib/silccrypt/silccrypt.[ch].
5071 * The same thing was done to silc_hash_* as for silc_cipher_*
5072 routines. Affected files lib/silccrypt/silchash.[ch].
5074 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5075 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5076 Added also silc_pkcs_[un]register[_default] functions.
5077 Removed the data_context from the PKCS API.
5079 * Added silc_hmac_register_default function to register default
5080 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5081 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5082 to unregister all hmacs at once.
5084 * Register the default ciphers, hash functions, PKCSs and HMACs
5085 if client's configuration file does not exist. The affected
5088 * The client did not load the hash functions from the SIM
5089 modules at all. Added support for this. Affected file is
5090 silc/clientconfig.c.
5092 * When decoding public key with silc_pkcs_public_key_decode, check
5093 the supported algorithm only if PKCS are registered. Affected
5094 file lib/silccrypt/silcpkcs.c. The same was done with the
5095 silc_pkcs_private_key_decode.
5097 * Fixed the SILC List routines to keep the list always in order.
5098 It used to change the list's order when traversing the list but
5099 not it preserves the order. Affected file lib/trq/silclist.h.
5101 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added the client library to use the SilcSocketConnection's
5104 reference counter (by silc_socket_dup) to prevent the bug that
5105 the socket object may be freed underneath async operation.
5107 * The name resolv library checking fixes in the configure.in.pre.
5110 * Created new version of the protocol drafts for future
5111 development. The -03 drafts are the ones that will be changed
5112 in the trunk now and the -02 will remain as they are.
5114 * Send list of CUMODE notifys to the router when announcing
5115 the channel users to the router. Affected file silcd/server.c.
5116 If the router receiving channel founder CUMODE for a channel
5117 that already has channel founder it will send CUMODE notify
5118 to the sender to remove the channel founder rights from the
5119 announced client. Affected file silcd/packet_receive.c.
5121 * The CUMODE notify may now use Server ID as well as the entity
5122 who changes the mode. Updated protocool specs.
5124 * Updated INSTALL and README files.
5126 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * New web pages in the http://silc.pspt.fi. The pages was
5133 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Implemented the [DenyConnectin] config section in the server.
5136 Added silc_server_config_denied_conn to check whether incoming
5137 connection is denied. Affected file silcd/serverconfig.[ch].
5139 * Do not check the ports when checking the incoming configuration
5140 data if the port is 0, meaning any. Affected file is
5141 silcd/serverconfig.c.
5143 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Fixed buffer overflow in silc_string_compare in the file
5146 lib/silcutil/silcutil.c.
5148 * Fixed double free in silc_server_command_leave in the file
5151 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Fixed the version checking in the server. Affected file is
5156 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Fixed the configuration data fetching when accepting new
5159 connections in the server. Affected file silcd/server.c.
5161 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Added `sender_entry' argument to the function
5164 silc_server_packet_relay_to_channel so that we can check
5165 whether some destination actually belongs to the same route
5166 the sender belongs (ie, we must not resend the packet to the
5167 sender). Affected file silcd/packet_send.[ch].
5169 * Added `servername' field to the SilcClientEntry in the server
5170 to hold the name of the server where client is from. Affected
5171 file is silcd/idlist.h.
5173 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Moved the channel message encrypting in the router betwen
5176 router connections from silc_server_channel_message to the
5177 silc_server_packet_relay_to_channel since we want to check
5178 whether we have anybody channel before encrypting anything.
5179 Affected files silcd/packet_[receive/send].c.
5181 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Fixed the [AdminConnection] server config section to support
5184 multiple entries. Affected file silcd/serverconfig.c.
5186 * Added support into the server to check the validity of the
5187 incoming connection before executing any KE or authentication
5190 * The connection configuration is now saved to the KE and
5191 connection auth protocol contexts and not fetched anymore in
5192 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5194 * The local hosts listenning address and port is also resolved
5195 now when starting the server. We want to have the socket object
5196 to include the real address and port for the listener. Added
5197 new function silc_net_check_local_by_sock into the files
5198 lib/silcutil/silcnet.[ch].
5200 * Fixed a broadcast bug in server -> do not broadcast if we
5203 * Fixed a routing bug. Do not route broadcast packets ever.
5204 Broadcast packets must be processed always and not routed since
5205 they may be destined to some other host than yourself and thus
5206 would get routed without no good reason. Affected file is
5209 * Added function silc_server_config_is_primary_route to check
5210 whether primary router connection has been configured (a router
5211 configuration that we are initiating). If there is not, we
5212 will assume that there is only two routers in the SILC network
5213 and we will use the incoming router connection as our primary
5214 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5216 * Changed the order of the broadcasting. Broadcast _after_ the
5217 packet has been processed not before. Affected file is
5220 * Fixed a [ClientConnection] parsing bug. The port was never
5221 parsed correctly thus resulting to port 0. Affected file
5222 silcd/serverconfig.c.
5224 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5225 argument and did not set the broadcast packet flag. Affected
5226 file silcd/packet_send.c. Fixed same bug in the function
5227 silc_server_send_notify as well.
5229 * If we receive NEW_ID packet for our own ID in the server, ignore
5232 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Removed the nickname from the Private Message Payload.
5237 Updated the code and the protocol specs.
5239 * Updated protocol specs for submitting to the IETF.
5241 * Tweaked the Random Number Generator a bit. Affected file
5242 lib/silccrypt/silcrng.c. Exported a new function
5243 silc_rng_[global]_add_noise which can be used to add more
5246 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Do not parse packets with different timeout when protocol
5249 is active -> may cause problem with rekey. Affected file
5252 * When server receives signoff notify it must not create
5253 new channel key if the client is on any channels since the
5254 sender of the signoff notify will create it.
5256 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added printing of error messages during SKE protocol from the
5259 failure packet sent by server during SKE. Affected file
5262 * Removed the client's failure_callback handling with timeout
5263 and handle it immediately when received.
5265 * The SKE library returned wrong type in SUCCESS and FAILURE
5266 packets. They must be 32 bit MSB not 16 bit MSB.
5268 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Ok, rewrote the logic of the re-key and now it seems to work.
5271 I tested it on high traffic with frequent re-keys without
5272 problems. Added hmac_receive (and renamed hmac to hmac_send)
5273 in SilcClientConnection in lib/silcclient/client.h and
5274 in SilcIDListData in silcd/idlist.h. Also, removed the
5275 SilcPacketParserContext's cipher and hmac fields as they are
5276 not needed anymore and actually caused some problems when
5277 the ciphers and hmac's changed underneath the packet parser.
5279 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * If re-key protocol is active then process the incoming packets
5282 synchronously since we must assure that icoming packets encrypted
5283 with the old key is processed before the new keys is set to
5284 use. This is true other packets than for REKEY packets.
5285 Affected file silcd/server.c. The same was done to client library
5286 as well, affected file lib/silcclient/client.c.
5288 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed bug in client and server to accept the force send if
5291 the packet is send from silc_[server/client]_packet_process
5292 function. Otherwise the packets are never delivered, oops.
5294 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Disable force sending of packets when REKEY protocol is active.
5297 We must assure that no packet is sent directly when rekey is
5298 performed. All packets must be sent through packet queue.
5299 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5300 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5301 function is silc_[server/client]_packet_send_real to check
5304 * Replaced the SIM paths from example config files to
5305 /usr/local/modules. Also, make install creates now
5306 /usr/local/silc/logs directory to hold all the SILC server
5309 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Made the configure.in.pre work on Solaris. Patch by salo.
5313 * Made all ciphers compatible with non-x86 machines. Defined
5314 CBC mode macros into lib/silccrypt/ciphers_def.h.
5316 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Fixed the make install.
5320 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * When MAC computation fails the silc_packet_decrypt returned 0
5323 even though it was supposed to return -1. Fixed this. The
5324 affected file is lib/silccore/silcpacket.c.
5326 * Do not replace the config files in /etc/silc (in make install)
5327 if they already exist. Affected file ./Makefile.am.
5329 * Do not send re-key packets immediately but through packet queue.
5330 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5332 * Changed silc_net_check_host_by_sock to return FALSE if the
5333 IP/DNS could not be resolved. Though, it returns the IP address
5334 now even if it could not resolve it (but returns also FALSE).
5335 Affected file lib/silcutil/silcnet.[ch].
5337 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Added silc_pkcs_decode_identifier to decode the public key's
5340 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5341 Added also silc_pkcs_free_identifier. Added also new context
5342 SilcPublicKeyIdentifier.
5344 * Added -S option to the silc client. It is used to dump the
5345 contents of the specified public key file.
5347 * Changed the PKCS api to return the public key length when
5348 setting the public key.
5350 * Fixed a fatal bug in the public and private key file loading.
5351 Affected file lib/silccrypt/silcpkcs.c.
5353 * Execute the packet parsing for client with zero (0) timeout
5354 if the protocol is active. Affected file silcd/server.c.
5356 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Made the key generation options to the silcd program. Added
5359 -C option, equivalent to client's option.
5361 * Added new [ServerKeys] config section to the server. It
5362 configures the server's public and private key.
5364 * Defined generic Public Key Payload into the protocol
5365 specification to send specific type of public keys and
5368 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5369 public key or certificate.
5371 * Implemented the GETKEY command to the server and to the
5372 client library and on user interface.
5374 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Made preliminary `make install' work.
5378 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added SilcServerRekey context into silcd/idlist.h.
5382 * Added the PFS support as defined in the specification to the
5383 SKE protocol. Affected files lib/silcske/*.c.
5385 * Added `ske_group' field to the SilcServerRekey context to hold
5386 the number of the SKE group that is used with PFS in re-key.
5387 Affected file silcd/idlist.h.
5389 * Added PFS re-key support to the server. Affected file is
5392 * Added silc_protocol_cancel to cancel execution of the next
5393 state of the protocol. Affected file is
5394 lib/silccore/silcprotocol.[ch].
5396 * Added the re-key support with and without PFS to the client
5397 library. Re-key is performed once in an hour, by default.
5399 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5400 Added silc_client_rekey_callback and silc_client_rekey_final.
5401 Affected files are lib/silcclient/protocol.[ch] and
5402 lib/silcclient/client.[ch].
5404 * Removed the `hmac_key' and `hmac_key_len' fields from the
5405 SilcClientConnection structure; not needed. Affected file is
5406 lib/silcclient/client.h.
5410 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Do not ask whether user wants to use the negotiated private key
5413 for private messages, just use it. Affected file is
5414 silc/local_command.c.
5416 * Added `send_enc_key' and `enc_key_len' fields to the
5417 SilcIDListData structure since they are needed in the re-key
5418 phase. Affected file is silcd/idlist.[ch].
5420 * Implemented the simple re-key protocol into the server.
5421 Affected files silcd/server.c and silcd/protocol.[ch]. The
5422 re-key will be performed once in an hour, by default.
5424 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5425 Added silc_server_rekey, silc_server_rekey_callback and
5426 silc_server_rekey_final.
5428 * Removed Tunneled flag from the protocol. Updated the code
5429 and the specifications.
5431 * Adde `pfs' field to the SilcIDListData to indicate whether
5432 the PFS is to be performed in the re-key. Affected file is
5435 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5438 int64 of at least the xintXX size. If void * is less that 4
5439 bytes uint32 * will be used. Defined bool as boolean.
5441 * Changed _ALL_ unsigned long and unsigned int to uint32,
5442 unsgined short to uint16 in the source tree.
5444 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5445 not handle clients that has entry->data.registered == FALSE.
5446 They are not in the network anymore. Affected file is
5449 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Implemented the sending of the SERVER_SIGNOFF notify in the
5452 server. Affected file is silcd/server.c.
5454 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5455 Added also silc_notify_payload_encode_args into the
5456 lib/silccore/silcnotify.[ch].
5458 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5459 Affected file silcd/packet_receive.c.
5461 * Implemented the SERVER_SIGNOFF notify handling in the client
5462 library. Affected file lib/silcclient/client_notify.c. Also,
5463 implemnted the printing of the SERVER_SIGNOFF info to the
5464 application. Affected file silc/client_ops.c.
5466 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5467 if the deleting was successful. Affected file silcd/idlist.[ch].
5469 * Added support for public key authentication in the connection
5470 authentication protocol in the client library. Affected file
5471 lib/silcclient/protocol.c.
5473 * Changed the server's silc_idlist_get_clients_by_* interface
5474 to support already allocated array so that new entries may be
5475 added to pre-allocated array. Affected file silcd/idlist.[ch].
5476 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5477 and command replies.
5479 * All command reply functions in the server now calls the
5480 pending command callback even if error occured. This way the
5481 error will be delivered to the client as well. Affected files
5482 silcd/command.c and silcd/command_reply.c.
5484 * Fixed INFO command to return local server's info if no server
5485 was provided. Affected file lib/silcclient/command.c.
5487 * Removed RESTART command for good. Updated the code and the
5490 * Rewrote parts of the task system. It is a bit simpler now.
5491 Removed unsued task priorities. The affected files are
5492 lib/silcutil/silctask.[ch].
5494 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Moved the USERS printing from the library to the application.
5497 Affected files lib/silcclient/command.c and silc/client_ops.c.
5499 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added channel key re-key support. The re-key is perfomed
5504 only by the router and is done once in an hour. Added `rekey'
5505 field to the SilcChannelEntry in the server. Affected files
5506 silcd/server.c and silcd/idlist.h.
5508 * Added silc_task_unregister_by_context into the file
5509 lib/silcutil/silctask.[ch].
5511 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added SILC_UMODE_GONE mode to indicate when the client is not
5514 present in the SILC network. Added also support to the local
5515 command AWAY that will set this mode. Added support of showing
5516 "xxx is gone" in WHOIS command. The USERS command shows the
5517 gone status as well.
5519 * Fixed setting server and router operator privileges in the
5520 server's UMODE command. Affected file silcd/command.c.
5522 * Merged the SKE KE1 and KE2 payloads into one payload. The
5523 new KE payload is equivalent to the old KE2 payload.
5525 Cleaned up the SKE Start Payload parsing. It now uses the
5526 simple buffer unformatting to do the parsing. A lot faster
5529 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5530 to the SKE that is used to indicate whether both of the SKE
5531 parties should perform authentication. By default only the
5532 responder performs authentication. By setting this flag also
5533 the initiator must do authentication. By default it is unset
5534 since in normal SKE case, client to server connection, only
5535 the responder should do authentication. When doing SKE between
5536 two clients both should perform authentication. Updated the
5537 code and the protocol specs.
5539 * A little fix to IDENTIFY command in the server. Search the
5540 client first by hash not nickname. Affected file is
5543 * Fixed the silc_client_close_connection to support closing
5544 the client to client connections wihtout deleting too much
5545 data. Affected file lib/silcclient/client.c.
5547 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5548 are received if protocol used to be active but is not anymore
5549 the application would crash due to NULL pointer dereference.
5550 Affected files silcd/server.c and lib/silcclient/client.c.
5552 * Added `hash' field to the SilcClientConnection to include
5553 the hash function negotiated in the SKE protocol.
5555 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5556 to set the channel founder authentication data. A client can
5557 claim the founder rights later by providing the authentication
5558 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5559 This way the channel founder can regain the channel founder
5560 privileges even it is left the channel. This works only on
5561 local server and the client must be connected to the same
5562 server to be able to regain the founder rights. Updated the
5563 protocol specs accordingly.
5565 Added support to the CMODE command in the client to set the
5566 founder auth data. Read the README to see how to set it.
5568 Added support to the CUMODE command to claim the founder
5569 rights. Read the README to see how to do it.
5571 Added support for the founder authentication to the Channel
5572 Entry in the server. Affected file silcd/idlist.h.
5574 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5575 server's CMODE command. Affected file silcd/command.c.
5577 * Added the following new functions into lib/silccore/silcauth.[ch]:
5578 silc_auth_get_method and silc_auth_get_data.
5580 * The server now saves the remote hosts public key to the
5581 SilcIDListData pointer. Affected file silcd/protocol.c.
5583 * The normal server now does not remove the channel entry from
5584 the cache if the founder authentication data is set. It used
5585 to remove it if the founder was the last one on the channel on
5586 the server and left the channel. The auth data is saved and
5587 if the channel is re-joined later the old entry is used with
5588 the old auth data. Affected files silcd/command_reply.c and
5591 * Removed the `pkcs' field from the SilcIDListData structure
5592 in the server; it is not used. Affected file silcd/idlist.h.
5594 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Fixed packet processing on slow links. Partial packets were
5597 never re-processed because the incoming data buffer was cleared
5598 by the application. Application must not directly clear the
5599 sock->inbuf, the packet processing routines handle it. Fixed
5600 this in client library and in server.
5602 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Fixed the WHOIS and IDENTIFY send reply function to really
5605 check whether to send list or just one entry. Affected file
5608 * Cleaned up the LEAVE command's channel key distribution. The
5609 affected file silcd/command.c.
5611 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5612 can enforce the channel mode as well. In that case the ID
5613 includes the ID of the server. The code now enforces the
5614 mode change if the router have different mode than the server.
5616 * The notify client operation with CMODE_CHANGE notify can now
5617 return NULL client_entry pointer if the CMODE was not changed
5618 by client. Application must check for this.
5620 * Added <Server ID> argument to INFO command to support server
5621 info fetching by Server ID.
5623 * Added silc_server_announce_get_channel_users to get assembled
5624 packets of channel users of the specified channel. Affected
5625 file silcd/server.[ch].
5627 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5628 was freed underneath the ID Cache.
5630 * Re-announce clients when the server received CHANNEL_CHANGE
5631 notify from the router. Affected file silcd/packet_send.c.
5633 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5636 crashed since it did not handle the fact that there is no cipher
5637 called "3" and didn't check the error condition. Now fixed.
5639 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5640 flag. It can be used to send message requests.
5642 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Implemented the RESTART command in the client.
5646 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5647 notice type messages. Added notice printing to the user
5650 * The channel keys are not re-generated if the channel's mode
5651 is PRIVKEY, ie private key on the channel exists. Affected
5652 files silcd/server.c and silcd/command.c.
5654 * Fixed a little bug in channel message delivery when channel
5655 private keys are set in the server. Affected file is
5656 silcd/packet_send.c.
5658 * Changed the setting on channel->on_channel = TRUE from the
5659 silc_client_save_channel_key to the JOIN command reply. The
5660 key payload is not received if the private channel key is set.
5661 Affected file lib/silcclient/command_reply.c and the
5662 lib/silcclient/client_channel.c.
5664 * When the CMODE_CHANGE notify is sent and the channel private
5665 key mode is removed the channel key must be re-generated in
5666 other cells as well. Added this support for the router in the
5667 silcd/packet_receive.c.
5669 * Added new local command NOTICE to send notice message on
5670 channel. Affected file silc/local_command.[ch].
5672 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Added new local command ME to the client. It is used to send
5675 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5676 some action. Affected file silc/local_command.[ch].
5678 * Changed channel_message and private_message client operations
5679 to deliver the message flags to the application. Added also
5680 the `flags' arguments to the silc_client_send_channel_message
5681 and silc_client_send_private_message functions. Affected file
5684 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Redefined the Private Message Payload to support private message
5687 keys and to support the new private message flags. Updated
5688 the protocol specs. Flags makes it possible to have for example
5689 CTCP style messages.
5691 * Added new type SilcPrivateMessagePayload and defined an API
5692 for it in the lib/silcclient/silcprivate.[ch].
5694 * Tested private message private keys successfully. Tested the
5695 private message key set, unset and list commands with the new
5698 * Redefined the Channel Message Payload to include the channel
5699 message flags (equal with private message flags) to support
5700 for example CTCP style messages.
5702 * Defined some of the message (for channel and private message)
5703 flags. Updated the protocol specs and added the flags to the
5704 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5706 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added SilcKeyAgreementStatus type to the key agreement routines
5709 to indicate the current status and error if one occured.
5710 The status types are defined in the lib/silcclient/silcapi.h.
5712 * Added new local command KEY that is used to set and unset private
5713 keys for channels, set and unset private keys for private messages
5714 with remote clients and to send key agreement requests and
5715 negotiate the key agreement protocol with remote client. The
5716 key agreement is supported only to negotiate private message keys,
5717 it currently cannot be used to negotiate private keys for channels,
5718 as it is not convenient for that purpose.
5720 * Fixed a minor pending callback setting bug in the function
5721 silc_client_get_client_by_id_resolve, now the function works.
5722 Affected file lib/silcclient/idlist.c.
5724 * Added function silc_net_get_local_port to get local bound
5725 port by socket. Added to lib/silcutil/silcnet.[ch].
5727 * Added `sockets' and `sockets_count' fields to the SilcClient
5728 object. They hold the sockets of the listenning sockets in
5729 the client. Listenning sockets may be for example the key
5730 agreement server. Affected file lib/silcclient/client.[ch].
5731 Added functions the silc_client_add_socket and the
5732 silc_client_del_socket. They are exported to the application
5735 * Added ~./silc/clientkeys to support other client's public keys.
5737 * Renamed verify_server_key client operation to verify_public_key
5738 and added one argument to indicate the type of the connection
5739 (server, client etc.).
5741 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added silc_server_connection_auth_request to handle the
5744 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5745 silcd/packet_receive.[ch].
5747 * Added silc_server_send_connection_auth_request into the
5748 silcd/packet_send.c to send the connection auth request packet.
5750 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5753 * Fixed the public key authentication in responder side in the
5754 server. The `auth_data' pointer includes the SilcPublicKey
5755 not the path to the public key. Affected file silcd/protocol.c.
5757 * Implemented the public key authentication in the initiator side
5758 in the server. Affected file silcd/protocol.c.
5760 * Removed the [RedirectClient] config section from the server
5761 configuration. Is not needed and I don't want to implement it.
5763 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Cleaned up the CMODE command in the server. It now works
5766 correctly and supports all the modes defined in the protocol.
5767 Affected file is silcd/command.c.
5769 * Added `hmac_name' field to the SilcChannelEntry in the server
5770 to hold the default HMAC of the channel. It can be set when
5771 creating the channel (with JOIN command). Affected files
5774 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5775 type to indicate the change of the current cipher and hmac
5776 on the channel. Client can safely ignore the <cipher> argument
5777 (if it chooses to do so) since the CHANNEL_KEY packet will
5778 force the channel key change anyway. The <hmac> argument is
5779 important since the client is responsible of setting the new
5780 HMAC and the hmac key into use.
5782 * Fixed the CMODE command in the client library as well.
5784 * Tested CMODE command in router environment successfully.
5786 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Show the version of the remote client (or server) when connecting
5789 to the server. It is logged to the log file. Affected file
5790 is silcd/protocol.c.
5792 * Fixed the KILLED notify handling in the client library. The
5793 client must be removed from all channels when receiving the
5796 Also, do not remove the client entry when giving the KILL
5797 command but when the KILLED notify is received.
5799 * Removed silc_idlist_find_client_by_nickname from the server.
5800 Not needed anymore. Affected files silcd/idlist.[ch].
5802 * Implemented the CHANNEL_CHANGE notify type handling to the
5803 server. Affected file silcd/server.c.
5807 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Added silc_server_send_notify_invite to send the INVITE
5810 notify between routers.
5812 * Implemented the INVITE command correctly to the server.
5814 * Implemented the INVITE notify type handling in the server.
5816 * Implemented the INVITE command to the client library and on the
5819 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Added function silc_server_get_client_resolve to find the
5822 client entry by ID from all ID lists and then resolve it
5823 (using WHOIS) if it cannot be found. Affected file is
5826 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Implemented the BAN command to the client library.
5830 * The JOIN command in the server now checks the invite list
5833 * Changed the silc_command_reply_payload_encode_va and the
5834 silc_command_payload_encode_va to support that if argument is
5835 NULL it ignores and checks the next argument. Affected file
5836 lib/silccore/silccommand.c.
5838 * Added silc_server_send_notify_ban to send the BAN notify
5839 type between routers.
5841 * Chaned the silc_notify_payload_encode to support that if
5842 argument is NULL it ignores and checks the next argument.
5843 Affected file lib/silccore/silcnotify.c.
5845 * Tested ban lists in router environment successfully.
5847 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Implemented BAN command to the server, in silcd/command.[ch].
5851 * Removed the BAN and INVITE_LIST modes from the CMODE command
5854 * Added function silc_string_match to regex match two strings.
5855 Affected files lib/silcutil/silcutil.[ch].
5857 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Redefined parts of the SilcChannelEntry in the server to support
5860 the new ban and invite lists.
5862 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Redefined the INVITE command. The same command can be used to
5865 invite individuals to the channel but also to manage the invite
5866 list of the channel (to add to and remove from the invite list).
5867 Updated the protocol specs.
5869 * Added new command SILC_COMMAND_BAN that can be used to manage
5870 the ban list of the channel. Updated the protocol specs.
5872 * Removed the channel modes: the SILC_CMODE_BAN and the
5873 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5874 in the CMODE command. The equivalent features are now available
5875 using INVITE and BAN commands. Updated the protocol specs.
5877 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5878 in the network about change in the current ban list. The notify
5879 type is not used by the client.
5881 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5882 support the invite lists.
5884 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added new function silc_string_regexify that converts string
5887 including wildcard characters into regex string that can
5888 be used by the GNU regex library. Added into the file
5889 lib/silcutil/silcutil.[ch].
5891 Added silc_string_regex_combine to combine to regex strings
5892 into one so that they can be used as one regex string by
5893 the GNU regex library. Added into the file
5894 lib/silcutil/silcutil.[ch].
5896 Added silc_string_regex_match to match two strings. It returns
5897 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5899 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Imported GNU regex to the soruce tree into lib/contrib.
5902 Fixed some compiler warning from the regex.c.
5904 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Fixed MOTD command in the server to work in router environment.
5908 * Fixed the MOTD command in the client library to support
5909 the server argument in the command.
5911 * Added `nickname_len' argument to the silc_idlist_add_client
5912 in the server, as the `nickname' argument may be binary data
5915 * Added silc_idlist_get_channels to return all channels from
5918 * Implemented LIST command to the server. Affected file is
5921 * Implemented the LIST command to the client library and on the
5924 * Added [<user count>] argument to the LIST command reply.
5925 With private channels the user count is not shown.
5927 * Updated TODO and README.
5929 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * The client entry's data.registered must be TRUE even with
5932 global client entry on global client list. The data.registered
5933 is used to check whether the client is anymore in the network,
5934 for example with WHOWAS command so it must be valid.
5936 * Fixed the WHOWAS command in the server. It now actually works
5937 in router environment. Added function into silcd/command_reply.c
5938 silc_server_command_reply_whowas_save.
5940 * Added silc_idlist_purge function to the silcd/idlist.c
5941 to periodically purge the ID Cache.
5943 * Fixed INFO command in the server. It works now in router
5944 environment. Added <server name> argument to the INFO command
5945 reply. Updated the protocol specs.
5947 * Fixed minor bug in silc_idcache_purge to not purge if the
5948 expire value is zero.
5950 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5951 they were buggy because of the WHOWAS information.
5953 * Fixed local command MSG to handle the async resolving of
5954 the remote client properly. It used to fail the first MSG.
5955 Affected file silc/local_command.c.
5957 * Added `data_len' field to SilcIDCache context.
5959 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Update TODO. Todo in commands in the server.
5963 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5966 used by routers as broadcast packet to inform other routers
5967 about the changed user mode.
5969 Implemented the notify handling in the server. Affected file is
5970 silcd/packet_receive.c. Added the function
5971 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5973 * Added new generic Channel Payload and deprecated the New Channel
5974 Payload. The New Channel Payload is now the generic Channel
5977 * Added new argument `mode' to the silc_server_send_new_channel
5978 as it is required in the Channel Payload now.
5980 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5981 and created a new and real SilChannelPayload to represent the
5982 new generic Channel Payload. Implemented the encode/decode
5983 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5985 * Added silc_server_get_client_channel_list to return the list
5986 of channels the client has joined for WHOIS command reply.
5987 Affected file silcd/server.[ch].
5989 * Implemented the channel list sending in the WHOIS command reply
5990 in server and in the client.
5992 Implemented the channel list displaying on the user interface
5993 as well. Affected file silc/client_ops.c.
5995 * Added silc_channel_payload_parse_list to parse list of Channel
5996 Payloads. It returns SilcDList list of SilcChannelPayloads.
5997 Client for example can use this function to parse the list of
5998 channels it receives in the WHOIS command reply. The caller
5999 must free the list by calling silc_channel_payload_list_free.
6000 Affected files lib/silccore/silcchannel.[ch].
6002 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added one new argument <user mode> to the WHOIS command reply
6005 to return the mode of the user in SILC. Updated the protocol
6008 Implemented it to the server and client.
6010 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Fixed the mode printing on the user interface on joining.
6013 Affected file silc/client_ops.c.
6015 * Implemented the UMODE command and user modes in general to the
6016 client library and to the user interface.
6018 * Implemented the UMODE command to the server.
6020 * The server now sends UNKNOWN_COMMAND error status if client sends
6021 unknown command. Affected file silcd/command.c.
6023 * All server commands now handle the command identifier the right
6024 way when sending the command reply to the client. The client can
6025 use to identify the command replies with the identifier.
6027 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added silc_server_get_client_route to resolve the route to
6030 the client indicated by the client ID. Affected file is
6033 * Added silc_server_relay_packet as general function to relay
6034 packet to arbitrary destination. This deprecates functions
6035 like _send_private_message_key, _relay_notify etc. Affected
6036 file is silcd/packet_send.[ch].
6038 Removed silc_server_send_key_agreement,
6039 silc_server_send_private_message_key and
6040 silc_server_packet_relay_notify functions from the file
6041 silcd/packet_send.[ch].
6045 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6046 server. Affected file silcd/packet_receive.[ch].
6048 * Implemented the KILL command to the client. Implemented the
6049 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6050 Affected files lib/silcclient/command[_reply].c and
6051 lib/silcclient/client_notify.c. Implemented the KILL notify
6052 printing in the user inteface.
6054 * Fixed a lot silc_parse_nick memory leaks from the client
6055 library in the file lib/silcclient/command.c.
6057 * Changed the silc_server_send_notify_on_channels's `sender'
6058 argument from SilcSocketConnection to SilcClientEntry to
6059 check the sender as entry and not as connection object and not
6060 to send to the client provided as argument. The affected file
6061 is silcd/packet_send.[ch].
6063 * The notify packets that are destined directly to the client used
6064 to not to be processed by the server. Now changed that and the
6065 server processes all notify packets. After relaying the packet
6066 to the client the notify packet is processed in the server.
6068 * The silc_server_free_client_data now checks whether there is
6069 pending outgoing traffic for the client and purges the data to
6070 the network before removing the client entry.
6072 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6075 an client is killed from the SILC Network. Updated the protocol
6078 Added new function silc_server_send_notify_killed to the
6079 silcd/packet_send.[ch].
6081 * Added function silc_server_packet_relay_notify to relay notify
6082 packets that are destined directly to a client. In this case
6083 the server does not process the notify packets but merely relays
6084 it to the client. Affected file silcd/packet_send.[ch].
6086 Added also silc_server_packet_process_relay_notify to check
6087 whereto relay the notify. Affected file is
6088 silcd/packet_receive.[ch].
6090 * Implemented the KILL command to the server.
6094 * Added the backup schema desgined last fall to the protocol
6095 specs for everyone to see. The specification is in the
6096 *-spec-xx.txt draft and the packet type definitions for the
6097 backup routers is in *-pp-xx.txt draft. Thusly, added also
6098 new packet type SILC_PACKET_CELL_ROUTERS.
6100 * A big security problem in the implementation discovered. The
6101 signoff of an client did not cause new channel key generation
6102 which it of course should've done. The channel keys must be
6103 always re-generated when client leaves (or signoffs) the channel.
6104 The silc_server_remove_from_channels funtion now handles
6105 the channel key re-generation.
6107 * Added `sender' argument to the silc_server_send_notify_on_channels
6108 to not to send the client provided as argument. Affected file
6109 silcd/packet_send.[ch].
6111 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Implemented OPER and SILCOPER commands into the server and
6116 * Added silc_auth_verify and silc_auth_verify_data to verify
6117 the authentication directly from the authentication payload.
6118 It supports verifying both passphrase and public key based
6119 authentication. Affected file lib/silccore/silcauth.[ch].
6121 * Added `hash' field to the SilcIDListData structure. It is the
6122 hash negotiated in the SKE protocol. Affected file is
6125 * Slight redesigning of the SilcAuthPayload handling routines.
6126 Do not send SilcPKCS but SilcPublicKey as argument.
6128 * Implemented the public key authentication support to the
6129 serverconfig. The public key is loaded from the provided path
6130 and saved as authentication data to void * pointer. Thus,
6131 changed the unsigned char *auth_data to void *auth_data;
6133 * Fixed SHUTDOWN command to send the reply before the server
6134 is shutdown. :) Affected file silcd/command.c.
6136 * Fixed fatal bug in CONNECT command. The hostname was invalid
6137 memory and server crashed. Affected file silcd/command.c.
6139 * Fixed fatal bug in CLOSE command. The server_entry became
6140 invalid but was referenced later in the command. Affected file
6143 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Fixed fatal bug in failure packet handling. Server ignored
6146 the failure and thus crashed when it came.
6150 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6153 that the command may be executed only once in (about) 2 seconds.
6154 The old SILC_CF_LAG flag is same but allows command bursts up
6155 to five before limiting.
6157 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6158 server code. Various commands now includes the CF_LAG_STRICT
6159 flag to disallow any kind of miss-use of the command.
6161 * Fixed the silc_buffer_unformat to not to allocate any data
6162 if the length of the data is zero. It used to allocate the
6163 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6165 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Changed the format of AdminConnection configuration section
6168 in the server. Added username of the admin to the format.
6169 Affected files silcd/serverconfig.[ch].
6171 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6172 to return admin configuration data by host, username and/or
6175 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Implemented WHOWAS command to the server. Added the functions:
6179 silc_server_command_whowas_parse,
6180 silc_server_command_whowas_send_reply,
6181 silc_server_command_whowas_from_client and
6182 silc_server_command_whowas_from_server
6184 * Added <Client ID> argument to the WHOWAS command reply. Updated
6185 the protocol specs accordingly.
6187 * Implemented WHOWAS command and command_reply to the client
6190 Implemented the WHOWAS printing on the user interface.
6192 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Added new argument to the WHOWAS command reply, the real name.
6195 It is an optional argument. Updated the protocol specs.
6197 * Added SilcIDCacheDestructor callback that is registered when
6198 the SilcIDCache is allocated. The callback is called when
6199 an cache entry in the ID Cache expires, or is purged from the
6200 cache. Added into lib/silccore/idcache.[ch].
6202 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6203 to destruct the client entries when the cache entry expires.
6204 Other ID Cache's in server and in the client library ignores
6207 * If the ID Cache entry's `expire' field is zero then the entry
6208 never expires. Added boolean `expire' argument to the
6209 silc_idcache_add function in the lib/silccore/idcache.[ch].
6210 If it is TRUE the default expiry value is used.
6212 * Added silc_server_free_client_data_timeout that is registered
6213 when client disconnects. By default for 5 minutes we preserve
6214 the client entry for history - for WHOWAS command.
6216 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Added support to the server to enforce that commands are not
6219 executed more than once in 2 seconds. If server receives
6220 commands from client more frequently, timeout is registered
6221 to process the commands. Affected file silcd/command.c.
6222 Added new function silc_server_command_process_timeout.
6224 * Changed NICK_NOTIFY handling in client library to check that
6225 if the client's nickname was changed, so there is no need to
6226 resolve anything from the server.
6228 * Removed error printing from the WHOIS and IDENTIFY commands.
6229 If error occurs then it is ignored silently in the client library.
6230 The application, however, may map the received error to
6231 human readable error string. The application currently maps
6232 the NO_SUCH_NICKNAME error to string.
6234 * Made the command status message public to the application. Moved
6235 them from lib/silcclient/command_reply.c to
6236 lib/silcclient/command_reply.h. The application can map the
6237 received command status to the string with the
6238 silc_client_command_status_message function.
6240 * Added check to the server to check that client's ID is same
6241 as the Source ID in the packet the client sent. They must
6244 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added dist-bzip hook to the Makefile.am to make bzip2
6247 compressed distributions.
6249 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Server now enforces the maximum length for the nickname and
6252 the channel as protocol specification dictates. 128 bytes for
6253 nickname and 256 bytes for channel name.
6255 * Moved the WHOIS printing to the application. The client libary
6256 does not print out the WHOIS information anymore, the application
6257 must do it. Renamed silc_client_command_reply_whois_print to
6258 the silc_client_command_reply_whois_save.
6260 The client's idle time is also sent to the application now, and
6261 the idle is shown on screen.
6263 * Added silc_client_command_reply_identify_save to save the
6264 received IDENTIFY entries.
6266 * Do not check for channel private keys in message sending and
6267 reception if the channel does not have the PRIVKEY mode set.
6268 Affected file lib/silclient/client_channel.c.
6270 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6273 just surfaced after chaning the JOIN procedure.
6275 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Added silc_client_get_clients_by_list to get client entries
6278 from Client ID list, that is returned for example by JOIN
6279 and USERS command replies. The application should use this
6280 function for example when JOIN command reply is received to
6281 resolve the clients already on the channel (library does not
6282 do that anymore as USERS command reply is not used in the JOIN
6283 procedure anymore). Affected files lib/silcclient/silcapi.h and
6284 lib/silcclient/idlist.c.
6286 * JOIN command reply and USERS command reply returns now SilcBuffer
6287 pointers instead of unsigned char pointers when returning
6288 the client list and mode list.
6290 * Added <Client ID> argument to the JOIN command reply, mainly
6291 for the server to identify for which client the command was
6292 originally sent. Updated protocol specs accordingly.
6294 * Added SilcDlist private_key pointer to the SilcChannelEntry
6295 in the client to support the channel private keys. Affected
6296 file is lib/silcclient/idlist.h.
6298 * Added SilcChannelPrivateKey argument to the function
6299 silc_client_send_channel_message so that application can choose
6300 to use specific private ke if it wants to. If it is not provided,
6301 the normal channel key is used, unless private keys are set.
6302 In this case the first (key that was added first) is used
6303 as the encryption key.
6305 * Implemented the support for channel private key handling.
6306 Implemented the following functions:
6308 silc_client_add_channel_private_key,
6309 silc_client_del_channel_private_keys,
6310 silc_client_del_channel_private_key,
6311 silc_client_list_channel_private_keys and
6312 silc_client_free_channel_private_keys
6314 Affected file lib/silcclient/client_channel.c.
6316 * Added the support for the private keys in the channel message
6317 sending and encryption and in the message reception and
6318 decryption. Affected funtions are
6319 silc_client_send_channel_message and silc_client_channel_message.
6321 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added SKE's key verify callback to the client library's
6324 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6326 * Removed the statement that server (or router) must send USERS
6327 command reply when joining to the channel so that the client
6328 knows who are on the channel. Instead, the client list and
6329 client's mode list is now sent in the JOIN command reply to the
6330 client who joined channel. This is better solution.
6332 * Added function silc_server_get_users_on_channel and function
6333 silc_server_save_users_on_channel to the silcd/server.[ch].
6335 * Removed function silc_server_command_send_users from the
6338 * Do not show topic on the client library anymore. The topic is
6339 sent in the command reply notify to the application and the
6340 application must show the topic now.
6342 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Added client searching by nickname hash into the IDENTIFY and
6345 WHOIS commands in the server as they were clearly missing from
6346 them. Affected file is silcd/command.c.
6348 * Fixed a bug in private message receiving in the client library.
6349 The remote ID was freed and it wasn't supposed, now it is
6352 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Minor fix to the channel payload; allocate the data area, as it
6355 needs to be of specific length.
6357 * If the key agreement port is zero then the operating
6358 system will define the bound port. Affected files are
6359 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6361 * Added new function silc_channel_payload_decrypt into the file
6362 lib/silccore/silcchannel.[ch].
6364 * Moved the channel message etc, check from silc_packet_decrypt
6365 to applications. The library calls now a generic
6366 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6367 when the packet is either normal or special. This was done to
6368 allow more wide range of checking that was not allowed when
6369 the code was in library. Now applications can do virtually any
6370 checks to the packet and return to the library the decision how
6371 the packet should be processed. Affected files are
6372 lib/silccore/silcpacket.[ch].
6374 Added silc_server_packet_decrypt_check to the server and
6375 silc_client_packet_decrypt_check to the client library.
6377 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6378 to send with specified source and destination information.
6380 * Channel message delivery between routers was broken after the
6381 channel key distribution was fixed earlier. The channel key
6382 was used be to distributed to other routers as well which is not
6383 allowed by the protocol. Now this is fixed and channel keys
6384 really are cell specific and the channel message delivery between
6385 routers comply with the protocol specification.
6387 * Fixed various commands in server to check also the global list
6388 for the channel entry and not just the local list. The affected
6389 file silcd/command.c.
6391 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Added assert()s to buffer formatting and unformatting routines
6394 to assert (if --enable-debug) when error occurs. Affected
6395 file: lib/silcutil/silcbuffmt.c.
6397 * Changed to auto-reconnect to check whether the remote host is
6398 router and register the re-connect timeout if it is. It used
6399 to check that whether we are normal server, but router must do
6400 auto-reconnect with another router as well. Affected file
6403 * Removed the [<key len>] option from CMODE command as the cipher
6404 name decides the key length, nowadays. See the defined ciphers
6405 from the protocol specification.
6407 * Added [<hmac>] option to the CMODE command to define the HMAC
6408 for the channel. Added SILC_CMODE_HMAC channel mode.
6410 * Added [<hmac>] option for the JOIN command so that user can
6411 select which HMAC is used to compute the MACs of the channel
6414 * Added Hmac field to the Channel Message Payload. The integrity
6415 of plaintext channel messages are now protected by computing
6416 MAC of the message and attaching the MAC to the payload. The
6417 MAC is encrypted. Now, it is clear that this causes some
6418 overhead to the size of the packet but rationale for this is that
6419 now the receiver can verify whether the channel message decrypted
6420 correctly and also when private keys are set for the channel the
6421 receiver can decrypt the packet with several keys and check from
6422 the MAC which key decrypted the message correctly.
6424 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6425 lib/silccrypt/silccipher.[ch].
6427 * Added silc_hash_len to return the digest length into the
6428 lib/silcrypt/silchash.[ch].
6430 * Rewrote parts of Silc Channel Payload interface in the
6431 lib/silccore/silcchannel.[ch]. The encode function now also
6432 encrypts the packet and parse function decrypts it.
6434 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Fixed a minor formatting bug in the SKE's key material processing.
6437 It actually might have processed the keys wrong way resulting
6440 * Redefined the mandatory HMAC algorithms and added new algorithms.
6441 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6442 and hmac-md5 truncated to 96 bits. The mandatory is now
6443 hmac-sha1-96. Rest are optional (including the one that used
6444 to be mandatory). Rationale for this is that the truncated HMAC
6445 length is sufficient from security point of view and can actually
6446 make the attack against the HMAC harder. Also, the truncated
6447 HMAC causes less overhead to the packets. See the RFC2104 for
6450 * Added new [hmac] configuration section. The SKE used to use
6451 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6452 is of course wrong. The official names that must be proposed in
6453 the SKE are the ones defined in the protocol specification
6454 (hmac-sha1-96 for example). The user can configure any hmac
6455 using any hash function configured in the [hash] section. At
6456 least, the mandatory must be configured.
6458 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6460 * Added HMAC list to the SKE proposal list. It has now both
6461 hash algorithm list and HMAC list. This makes the protocol
6462 incompatible with previous versions. The SKE now seems to work
6463 the way it is supposed to work, for the first time actually.
6465 * Defined plain Hash algorithms to the protocol specification.
6468 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Implemented support for key agreement packets into the server.
6471 Added functions silc_server_key_agreement and
6472 silc_server_send_key_agreement. Other than these functions,
6473 server has nothing to do with this packet.
6475 * Added support for private message key packets into the server.
6476 Added functions silc_server_private_message_key and
6477 silc_server_send_private_message_key.
6481 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6482 called in the protocol's final callback instead in the END
6483 protocol state. This makes a little more sense and in the same
6484 time in client we can use the same protocol routines for normal
6485 key exchange and to key agreement packet handling as well.
6487 * Added to both client's and server's KE protocol context the
6488 SilcSKEKeyMaterial pointer to save the key material. We will
6489 bring the key material to the protocol's final callback by doing
6490 this. The final callback must free the key material.
6492 * Added SKE's packet_send callback into client's KE protocol
6493 context so that the caller can choose what packet sending function
6494 is used. This way we can use different packet sending when
6495 doing normal SKE when doing key agreement packet handling (in
6496 the key agreement packet handling we do not want to encrypt
6499 * Implemented the responder side of the key agreement routines
6500 in the client. The client can now bind to specified port and
6501 accept incoming key negotiation. The key material is passed
6502 to the application after the protocol is over.
6504 * Implemented the processing of incoming Key Agreement packet
6505 in the client. Added function silc_client_key_agreement to
6508 * Implemented the intiator side of the key agreement routines
6509 in the client. The client can now initiate key agreement with
6510 another remote client. The key material is passed to the
6511 application after the protocol is over.
6513 * Created client_keyagr.c to include all the key agreement
6516 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6517 SILC_TASK_CALLBACK except that it is not static.
6519 * Created client_notify.c and moved the Notify packet handling
6520 from the client.[ch] into that file.
6522 * Created client_prvmsg.c and moved all private message and
6523 private message key routines from the client.[ch] into that file.
6525 * Create client_channel.c and moved all channel message and
6526 channel private key routines from the client.[ch] into that file.
6528 * Changed silc_client_get_client_by_id_resolve to resolve with
6529 WHOIS command instead of IDENTIFY command, in the file
6530 lib/silclient/idlist.c.
6532 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Implemented the SKE's responder side to the Client library.
6536 * When FAILURE is received to the protocol do not trust it
6537 blindly. Register a timeout to wait whether the remote closes
6538 the connection as it should do it, only after that process the
6539 actual failure. This was changed to both client and server.
6541 * Added client_internal.h to include some of the structures
6542 there instead of client.h in lib/silcclient/.
6544 * Added function silc_task_unregister_by_callback to unregister
6545 timeouts by the callback function.
6547 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Some "Incomplete WHOIS info" errors has been appearing on the
6550 log files. Took away the entry->userinfo check from WHOIS
6551 reply sending. The entry->userinfo is now " " if client did not
6552 provide one. I thought this was fixed earlier but something
6553 is wrong still. Let's see if the error still appears.
6555 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Fixed a minor bug in the login when the channel key is
6558 re-generated in the server. It used to generate the key in
6559 wrong order and thus caused problems in the channel traffic.
6561 * Fixed a minor bug in channel key distsribution after
6562 KICK command. The key was not sent to the router even though
6565 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Added silc_ske_process_key_material_data as generic routine
6568 to process any key material as the SILC protocol dictates. The
6569 function is used by the actual SKE library but can be used by
6570 applications as well. This relates to the private message keys
6571 and the channel private keys since they must be processed the
6572 same way the normal SILC session keys. The protocol dictates
6573 this. Affected files: lib/silcske/silcske.[ch].
6575 Added also silc_ske_free_key_material to free the
6576 SilcSKEKeyMaterial structure.
6578 * Defined silc_cipher_set_key function to set the key for
6579 cipher without using the object's method function. The affected
6580 files: lib/silccrypt/silccipher.[ch].
6582 * Implemented silc silc_client_add_private_message_key,
6583 silc_client_add_private_message_key_ske,
6584 silc_client_del_private_message_key,
6585 silc_client_list_private_message_keys and
6586 silc_client_free_private_message_keys functions in the
6589 Added functions silc_client_send_private_message_key to send
6590 the Private Message Key payload and silc_client_private_message_key
6591 to handle incoming Private Message Key payload.
6593 * Added Cipher field to the Private Message Key payload to set
6594 the cipher to be used. If ignored, the default cipher defined
6595 in the SILC protocol (aes-256-cbc) is used.
6597 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6599 * Removed lib/silcclient/ops.h file.
6601 Redefined parts of the SILC Client Library API. Created new
6602 file silcapi.h that deprecates the ops.h file and defines the
6603 published Client Library API. Defined also private message key
6604 API and channel private key API into the file.
6606 This is the file that the application must include from the
6607 SILC Client Library. Other files need not be included by
6608 the application anymore.
6610 * Added new key_agreement client operation callback and also
6611 defined the Key Agreement library API for the application.
6613 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6616 is used by clients to request key negotiation between another
6617 client in the SILC network. If the negotiation is started it
6618 is performed using the SKE protocol. The result of the
6619 negotiation, the secret key material, can be used for example
6620 as private message key.
6622 Implemented the Key Agreement payload into the files
6623 lib/silccore/silauth.[ch].
6625 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Redefined ciphers for the SILC protocol. Added some new ciphers
6628 and defined the key lengths for the algorithms. Changed the
6629 code accordingly. The default key length is now 256 bits.
6631 * Fixed SKE key distribution function silc_ske_process_key_material
6632 when the key length is more than 128 bits. The default key
6633 length in SILC is now 256 bits.
6635 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6636 to indicate unsupported algorithm.
6638 * Renamed rijndael.c to aes.c and all functions as well.
6640 * Fixed a long standing channel key setting bug in client library.
6641 Weird that it has never surfaced before.
6643 * Fixed bug in channel deletion. If the entire channel is removed
6644 then it must also delete the references of the channel entry
6645 from the client's channel list as the client's channel entry and
6646 the channel's client entry share same memory.
6648 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Implemented CONNECT and SHUTDOWN commands in the client.
6652 * Implemented CLOSE command to the client.
6654 * Added the function silc_idlist_find_server_by_name into the
6655 files silcd/idlist.[ch].
6657 Added the function silc_idlist_find_server_by_conn into the
6658 files silcd/idlist.[ch].
6660 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * DIE command was renamed to SHUTDOWN. Updated the both code
6665 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6666 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6668 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6671 * Added function silc_server_create_connection function to create
6672 connection to remote router. My server implementation actually
6673 does not allow router to connect to normal server (it expects
6674 that normal server always initiates the connection to the router)
6675 so the CONNECT command is only good for connecting to another
6678 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6681 or some other client was kicked from the channel.
6683 Implemented the handling of the notify type to both client
6686 Implemented silc_server_send_notify_kicked to send the KICKED
6687 notify. It is used to send it to the server's primary router.
6689 * Implemented the KICK command into server and client.
6691 * Added `query' argument to the silc_idlist_get_client function
6692 to indicate whether to query the client from server or not if
6695 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6696 to indicate that the client is not channel founder.
6700 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Removed the rng context from SilcPacketContext structure and
6703 changed that the packet routine uses the Global RNG API.
6705 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Added support for quit message that client can "leave" on the
6708 channel when it quits the SILC. It is ditributed inside the
6709 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6711 Added silc_server_free_client_data that will take the
6712 signoff message as argument.
6714 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6716 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Updated parts of the protocol specification to keep it up
6721 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6724 payloads in one packet.
6726 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6727 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6728 use now the new List flag.
6730 * Also deprecated the following packet types: REPLACE_ID,
6731 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6733 * Added list support for Notify packet in server.
6735 * Added silc_server_send_notify_channel_change to send the
6736 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6737 the silc_server_send_replace_id.
6739 * Added silc_server_send_notify_nick_change to send the
6740 NICK_CHANGE notify type. Deprecates the function
6741 silc_server_send_replace_id.
6743 * Added silc_server_send_notify_join to send the JOIN notify type.
6744 Deprecates the function silc_server_send_new_channel_user.
6746 * Added silc_server_send_notify_leave to send LEAVE notify type.
6747 Deprecates the function silc_server_send_remove_channel_user.
6749 * Added silc_server_send_notify_cmode and
6750 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6751 types. Deprecates the silc_server_send_set_mode function.
6753 * Added SERVER_SIGNOFF notify type to indicate that server has
6754 quit. This means that all clients on the channel from that
6755 server will drop. This can be also used when netsplit happens.
6757 Deprecated REMOVE_ID packet type since it is not needed anymore
6760 Added silc_server_send_notify_server_signoff to send the
6761 SERVER_SIGNOFF notify type. Deprecates the function
6762 silc_server_send_remove_id.
6764 Added also silc_server_send_notify_signoff to send the
6765 SIGNOFF notify type.
6767 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6768 SILC protocol from this day on. Changed the protocol
6769 specification as well.
6771 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6772 notify type. It is used between routers to notify about
6773 topic changes on a channel.
6775 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6778 * Partly updated the protocol specification to comply with the
6779 changes now made. It is still though a bit outdated.
6781 * The JOIN notify type now takes one extra argument <Channel ID>.
6782 The packet used to be destined to the channel but now the
6783 JOIN type may be sent as list thus it is impossible to
6784 destine it to any specific channel. By adding this argument
6785 it is again possible.
6787 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Added CREDITS file. The CHANGES and CREDITS file will appear
6790 in the distribution as well.
6792 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6795 types in the server's silcd/packet_receive.c.
6797 * Implemented CMODE and CUMODE to work in router environment.
6799 * Fixed minor encoding and decoding buglet from the
6800 lib/silccore/silcmode.c.
6802 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6805 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6807 * Changed all SilcConfigServer* and silc_config_server* to
6808 SilcServerConfig* and silc_server_config*, respectively.
6811 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Associated the ID (client or server ID) to the Authentication
6814 Payload to avoid any possibility of forging. Updated the
6815 protocol specification and the code accordingly.
6817 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * The RSA key length is now save to the RsaKey context in the
6820 key generation process in lib/silccrypt/rsa.c. The key length
6821 is now used to figure out the maximum size of the block allowed
6822 to be encrypted/signed.
6824 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6825 is equivalent to the silc_mp_mp2bin but does not allocate any
6828 * Changed silc_mp_mp2bin API to take length argument. If it is
6829 non-zero then the buffer is allocated that large. If zero, then
6830 the size is approximated using silc_mp_sizeinbase, which however
6833 * Created Global RNG API which is global RNG that application can
6834 initialize. After initializing, any routine anywhere in the
6835 code (including library) can use RNG without allocating a new
6836 RNG object. This was done to allow this sort of use of the
6837 RNG in code that has no chance to allocate RNG object. All
6838 applications currently allocate this and many routines in the
6839 library use this. Affected file lib/silccrypt/silcrng.[ch].
6841 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6842 it to use the Global RNG API.
6844 * Defined Authentication Payload into protocol specification that
6845 is used during SILC session to authenticate entities. It is
6846 used for example by client to authenticate itself to the server
6847 to obtain server operator privileges.
6849 Implemented this payload into the lib/silccore/silcauth.[ch].
6850 Implemented also routines for public key based authentication
6851 as the new protocol specification dictates.
6853 Moved definitions of different authentication methods from
6854 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6856 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6857 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6858 silc_pkcs_verify_with_hash functions into the file
6859 lib/silccrypt/silcpkcs.[ch].
6861 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * The client entry's userinfo pointer must be always valid.
6864 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6865 will fail since it requires the userinfo. Now, the userinfo
6866 is allocated as "" if actual userinfo does not exist. Actually,
6867 it must exist and it is totally Ok to drop client connections
6868 that does not announce the userinfo. However, we will make
6869 this workaround for now.
6871 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6872 to return the remote port by socket.
6874 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6876 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6877 SILC_SERVER_PENDING_EXEC and added an new macro
6878 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6879 data or when error occurs while processing the pending command.
6881 Added new argument `destructor' into silc_server_command_pending
6882 and to the SilcServerCommandPending object. This destructor is
6883 now called after calling the pending callback or if error occurs
6884 immediately. If error occurs the actual pending callback won't
6885 be called at all - only the destructor. The destructor may be
6886 NULL if destructor is not needed.
6888 All this applies for client library code as well. Similar
6889 changes were made there as well for the pending commands.
6891 In the client, the application must now allocate the
6892 SilcClientCommandContext with the silc_client_command_alloc
6895 * Added reference counter to the SilcServerCommandContext. Added
6896 function silc_server_command_alloc and silc_server_command_dup
6899 Same type of functions added to the client library for the same
6902 * Removed the cmd_ident from IDListData away since it is now
6903 global for all connections. It is the command identifier used
6904 in command sending and with pending commands. The affected file
6907 * Added reference counter to the SilcSocketConnection objecet to
6908 indicate the usage count of the object. The object won't be
6909 freed untill the reference counter hits zero. Currently only
6910 server uses this, and client ignores it. The client must be
6911 set to use this too later. The affected files are
6912 lib/silccore/silcsockconn.[ch]. Added also the function
6913 silc_socket_dup to increase the reference counter.
6915 This was mainly added because it is possible that the socket
6916 is removed underneath of pending command or other async
6917 operation. Now it won't be free'd and proper DISCONNECTING
6918 flags, etc. can be set to avoid sending data to connection that
6919 is not valid anymore.
6921 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6922 the connection. After that it sets SILC_SET_DISCONNECTED.
6923 It is, however, possible that the socket data is not still freed.
6924 The silc_server_packet_process now checks that data is not
6925 read or written to connection that is DISCONNECTED. The socket
6926 get's freed when the reference counter hits zero.
6928 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Changed the client operation API: channel_message operation's
6931 `sender' is now the client entry of the sender, not the nickname
6932 and the `channel' is the channel entry, not the channel name.
6934 In the private_message operation the `sender' is now also the
6935 client entry of the sender not the nickname.
6937 Affected file is lib/silcclient/ops.h and all applications
6938 using the client operations.
6940 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Moved the calling of ops->connect() from connect_to_server_final
6943 into receive_new_id functin since that is the point when the
6944 client is actually allowed to send traffic to network. The
6945 affected file is lib/silcclient/client.c.
6947 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6950 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6951 (if needs broadcasting) instead of broadcasting the packets one
6952 by one which would make a burst in the network traffic.
6954 * Added `broadcast' argument to the functions in silcd/server.[ch]
6955 silc_server_create_new_channel[_with_id] to indicate whether
6956 to send New Channel packet to primary router.
6958 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Added new function into the silcd/server.[ch] files:
6961 silc_server_create_new_channel_with_id to create new channel with
6962 already existing Channel ID.
6964 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6965 lib/silccore/silcpacket.h. This packet is used t send list of
6966 Set Mode payloads inside one packet. Server uses this to set
6967 the modes for the channels and clients on those channels, that it
6968 announced to the router when it connected to it. The protocol
6969 specification has been updated accordingly.
6971 * The silc_server_new_channel did not handle the packet coming
6972 from normal server as it normally does not send that. However,
6973 when it announces its channels it does send it. Implemented
6974 the support for that.
6976 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6977 into the file lib/silccore/id.h.
6979 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Fixed memory leaks in the functions silc_idlist_del_client,
6982 silc_idlist_del_channel and silc_idlist_del_server in the file
6983 silcd/idlist.c. All of those leaked like a sieve.
6985 * Fixed some small memory leaks in the client's function
6986 silc_client_notify_by_server.
6988 * Added functions into silcd/server.c: silc_server_announce_clients,
6989 silc_server_announce_channels and silc_server_announce_server.
6990 These functions are used by normal and router server to announce
6991 to its primary router about clients, channels and servers (when
6992 router) that we own. This is done after we've connected to the
6995 These functions effectively implements the following packet types:
6996 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6997 and SILC_PACKET_NEW_ID_LIST.
6999 * Added new functions into the silcd/packet_receive.[ch]:
7000 silc_server_new_id_list, silc_server_new_channel_list and
7001 silc_server_new_channel_user_list to handle the incoming
7002 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7004 * Added support of changing Channel ID in the function
7005 silc_server_replace_id. If the server that announces a channel
7006 to the router already exists in the router (with same name but
7007 with different Channel ID), router is responsible to send
7008 Replace ID packet to the server and force the server to change
7009 the Channel ID to the one router has.
7011 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7012 client that the Channel ID has been changed by the router. The
7013 normal server sends this to the client. Client must start using
7014 the new Channel ID as the channel's ID.
7016 Implemented handling of this new type into lib/silcclient/client.c
7017 into the function silc_client_notify_by_server.
7019 * Added new function silc_idlist_replace_channel_id into the files
7020 silcd/idlist.[ch] to replace the Channel ID.
7022 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Call silc_server_command_identify_check always when processing
7025 the IDENTIFY command in silcd/command.c
7027 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7029 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7030 send keepalive packets. The packet can be sent by clients,
7031 servers and routers.
7033 Added function silc_socket_set_heartbeat into the file
7034 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7035 If not set, the heartbeat is not performed. The actual
7036 heartbeat is implemented in the low level socket connection
7037 library. However, application is responsible of actually
7040 Added silc_server_send_heartbeat to send the actual heartbeat
7041 packet into silcd/packet_send.[ch]. Server now performs
7042 keepalive with all connections.
7044 * Added silc_task_get_first function into lib/silcutil/silctask.c
7045 to return the timeout task with shortest timeout. There was a bug
7046 in task unregistration that caused problems. TODO has been
7047 updated to include that task system must be rewritten.
7049 * The client library will now resolve the client information when
7050 receiving JOIN notify from server for client that we know but
7051 have incomplete information.
7053 * Rewrote parts of silc_server_remove_from_channels and
7054 silc_server_remove_from_one_channel as they did not remove the
7055 channel in some circumstances even though they should've.
7057 * Encryption problem encountered in server:
7059 The LEAVE command used to send the Channel Key packet to the
7060 router immediately after generating it. However, the code
7061 had earlier sent Remove Channel user packet but not immediately,
7062 ie. it was put to queue. The order of packets in the router
7063 was that Channel Key packet was first and Remove Channel User
7064 packet was second, even though they were encrypted in the
7065 reverse order. For this reason, MAC check failed. Now, this
7066 is fixed by not sending the Channel Key packet immediately but
7067 putting it to queue. However, this is more fundamental problem:
7068 packets that are in queue should actually not be encrypted
7069 because packets that are sent immediately gets encrypted
7070 actually with wrong IV (and thus MAC check fails). So, packets
7071 that are in queue should be encrypted when they are sent to
7072 the wire and not when they put to the queue.
7074 However, the problem is that the current system has not been
7075 designed to work that way. Instead, the packet is encrypted
7076 as soon as possible and left to the queue. The queue is then
7077 just purged into wire. There won't be any fixes for this
7078 any time soon. So, the current semantic for packet sending
7081 o If you send packet to remote host and do not force the send
7082 (the packet will be in queue) then all subsequent packets to the
7083 same remote host must also be put to the queue. Only after the
7084 queue has been purged is it safe again to force the packet
7087 o If you send all packets immediately then it safe to send
7088 any of subsequent packets through the queue, however, after
7089 the first packet is put to queue then any subsequent packets
7090 must also be put to the queue.
7092 Follow these rules and everything works fine.
7094 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Added new function silc_server_remove_clients_by_server to
7097 remove all client entries from ID list when the server connection
7098 is lost. In this case it is also important to invalidate all
7099 client entires as they hold the invalid server entry. This
7100 fixes fatal bug when server has lost connection and will reconnect
7103 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Made some sanity checks to silc_server_daemonise like to check
7106 whether the requested user and group actually exists.
7108 * Added sanity check to SKE's silc_ske_responder_finish to check
7109 that the public and private key actually is valid.
7111 * Invalidate the client's nickname when receiving Replace ID
7112 packet and the Client ID is being replaced. This means that the
7113 server will query the nickname if someone needs it (client)
7116 * Sort the ID Cache in client library when the ID Cache data
7117 has changed (needs sorting).
7119 * Do not allow for SILC client to create several connections to
7120 several servers. The client does not support windows right now
7121 and generating multiple connections causes weird behaviour.
7123 Irssi-silc client does support windows and can handle several
7124 connections without problems, see: www.irssi.org and SILC plugin.
7126 * Fixed some places where client was added to the IDList. The
7127 rule of thumb is following (in order to get everything right):
7128 If the client is directly connected local client then the
7129 `connection' argument must be set and `router' argument must be
7130 NULL to silc_idlist_add_client function. If the client is not
7131 directly connected client then the `router' argument must
7132 bet set and the `connection' argument must be NULL to the
7133 silc_idlist_add_client function.
7135 * The funtion silc_server_packet_send_local_channel actually did
7136 not check whether the client was locally connected or not. It
7137 does that now. Fixed a bug related to LEAVE command.
7139 * Fixed Remove Channel User payload parsing bug in server's
7140 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7142 * The server's silc_server_save_channel_key now checks also the
7143 global ID list for the channel as it might not be in the local
7144 list. Fixed a bug related to LEAVE command.
7146 * Is this the end of the [<unknown>] buglet that has been lurking
7147 around for a long time? A little for loop fix in server's
7148 silc_server_command_whois_parse that is used by both IDENTIFY
7149 and WHOIS command. At least, this was a clear bug and a cause
7150 of one type of [<unknown>] buglet.
7152 * WHOIS and IDENTIFY commands call the function
7153 silc_server_command_[whois/identify]_check function even if
7154 we are not router server.
7156 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Added --with-gmp configuration option. If set the GMP
7159 is always compiled in the SILC source tree. If not set then
7160 it is checked whether the system has the GMP3 installed. If
7161 it has then the GMP won't be compiled (the system's headers
7162 and library is used), if it doesn't have it then the GMP is
7163 compiled in the SILC source tree.
7165 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Changed RSA private exponent generation to what PKCS #1
7168 suggests. We try to find the smallest possible d by doing
7169 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7170 not security fix but optimization.
7172 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Added new config entry [Identity] to fork the server and run
7175 it as specific user and group. A patch from Bostik.
7177 * Imported Dotconf configuration library into lib/dotconf.
7178 This will be used to create the SILC configuration files later.
7179 It will appear in the distsribution after this commit.
7181 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * A big code auditing weekend happening. Auditing code for
7184 obvious mistakes, bugs and errors. Also, removing any code
7187 Removed files for being obsolete:
7189 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7190 inline in the file lib/silcutil/silcbuffer.h)
7192 o lib/silcutil/silcbufutil.c (the header has inline versions)
7194 Changed code to fix possible error conditions:
7196 o The buffer formatting routines now check that the destination
7197 buffer really has enough space to add the data. This applies for
7198 both buffer formatting and unformatting
7199 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7200 unformatting was changed to accomodate following rules:
7201 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7202 sent to the function while XXX_*STRING will not allocate or copy
7203 the data into the buffer. Instead it sets the pointer from the
7204 buffer into the pointer sent as argument (XXX_*STRING used to
7205 require that the pointer must be allocated already). This change
7206 makes this whole thing a bit more consistent and more optimized
7207 (note that the data returned in the unformatting with XXX_*STRING
7208 must not be freed now). The routines return now -1 on error.
7210 o Tried to find all code that use buffer_format and buffer_unformat
7211 and added return value checking to prevent formatting and
7212 especially unformatting errors and possible subsequent fatal
7215 o Changed ske->x and ske->KEY to mallocated pointers in
7216 lib/silcske/silcske.h. Fixed possible data and memory leak.
7218 o Added return value checking to all *_parse* functions. Fixed
7219 many memory leaks as well.
7221 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7222 so that buffer overflows would not happen. All code now also
7223 checks the return value as it can fail.
7225 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Added reconnection support to server if the normal server looses
7228 its connection to the router (for example if router is rebooted).
7229 The server performs normal reconnection strategy implemented
7230 to the server. Affected file silcd/server.c.
7232 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Added new packet type SILC_PACKET_SET_MODE that is used to
7235 distribute the information about changed modes (for clients,
7236 channels and clients channel modes) to all routers in the
7237 network. Updated the protocol specification accordingly.
7239 Added functions into silcd/packet_send.c and
7240 silcd/packet_receive.c: silc_server_send_set_mode,
7241 silc_server_set_mode.
7243 Added new files silcmode.[ch] into lib/silccore that implements
7244 the encoding and decoding of Set Mode Payload. Added new type
7245 SilcSetModePayload. Moved the definitions of different modes
7246 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7248 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Oops, a little mistake in server's connection authentication
7251 protocol. The protocol is not ended with FAILURE but with
7252 SUCCESS if the authentication is Ok. :) Affected file is
7255 * Implemented NICK_CHANGE notify handling in server in the file
7256 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7257 the local clients on the channel. After the changing nickname
7258 in router environment snhould work and the [<unknown>] nickname
7259 should appear no more.
7261 The silc_server_replace_id function that receives the Replace ID
7262 payload now sends the NICK_CHANGE notify type also in the file
7263 silcd/packet_receive.c
7265 * Changed WHOIS and IDENTIFY command to support the maximum amount
7266 of arguments defined in protocol specs (3328 arguments). This
7267 fixed a bug that caused problems when there were more than three
7270 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Added extra parameter, command identifier, to the
7273 silc_client_send_command so that explicit command identifier
7276 Changed that ID list routines uses specific command identifier
7277 when sending WHOIS/IDENTIFY requests to the server so that they
7278 can be identified when the reply comes back.
7280 Affected files lib/silcclient/command.[ch],
7281 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7283 * Added `sender' argument to silc_server_packet_send_to_channel
7284 to indicaet the sender who originally sent the packet to us
7285 that we are now re-sending. Ignored if NULL. Affected file
7286 silcd/packet_send.[ch].
7288 * Added some server statistics support in silcd/server_internal.h
7289 SilcServerStatistics structure and around the server code. Also
7290 send some nice statistics information when client is connecting
7293 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Fixed channel ID decoding in server's JOIN command reply in
7296 silcd/command_reply.c
7298 * Fixed braodcasting of replace ID payload to not to send it if
7299 we are standalone server in silcd/packet_receive.c.
7301 * Fixed all channel message sending routines to not to send
7302 packets to clients that has router set, since they are routed
7303 separately in the same function earlier. Affects file
7304 silcd/packet_send.c and all channel packet sending functions.
7306 * In USERS reply, res_argv[i] are not allocated, the table
7307 is allocated. Thus changed that free the table, not its
7310 * In server's whois_check and identify_check if the client is
7311 locally connected do not send any WHOIS commands - they are not
7314 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Fixed some minor bugs in client when sending WHOIS command. The
7317 arguments was in wrong order.
7319 * Removed statis function add_to_channel from server in
7320 silcd/command.c that was previously used with the joining but
7323 * Tested USERS command in router environment successfully with two
7324 routers, two servers and two clients.
7326 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Reorganized the USERS command and command reply in client library
7329 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7330 When the command is given by user we register a pending command
7331 callback that will reprocess the command after the reply has been
7332 received from the server. When reprocessing the packet we then
7333 display the information. Thus, the USERS information is displayed
7334 now in the command callback instead of in the command reply
7335 callback. The processing of the command is same as previously
7336 when server has sent the command reply in the JOINing process.
7338 * Added to USERS command in silcd/command_reply.c to join the client,
7339 we didn't use to know about, to the channel after we've created
7340 a client entry for it. Also, for clienet we did know already still
7341 check whether it is on the channel or not and add it if not.
7343 * Removed silc_server_command_join_notify as the function and its
7346 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Changed the client's pending command handling to the same as the
7349 server's pending command handling. It is also now possible to
7350 execute command reply functions from other command reply
7351 function as the function callbacks for commands and command
7352 replies are one and same. The pending commands are not static
7353 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7354 in client connection context. Thus, pending commands are server
7355 connection specific as it is convenient.
7357 Changed the function silc_client_command_pending and
7358 silc_client_command_pending_del and added new function
7359 silc_client_command_pending_check. Removed the
7360 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7363 * Added cmd_ident, current command identifier, to the client
7364 connection context in lib/silcclient/client.h to keep track on
7365 command identifiers used in command sending. Client's command reply
7366 function handling now supports the mandatory command identifiers.
7368 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7369 funtions in client to fully support pending command callbacks.
7371 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7372 as one of the arguments to the application in the command reply
7375 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7376 before first releasing SILC but came back. Now it is removed again
7377 and should come back nomore. The FORWARDED flag was used only
7378 by the JOINing procedure by forwarding the command packet to router.
7379 Now, the JOINing procedure has been changed to more generic (due
7380 to various router environment issues) and FORWARDED is not needed
7381 anymore for anything. The protocol specification is yet to be
7384 Now, removed silc_server_packet_forward from server and the flag
7385 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7387 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Renamed NAMES command to USERS command. The NAMES was named that
7390 due to historical reasons. Now it is renamed. Also, rewrote
7391 parts of the USERS command. The nickname list is not sent anymore
7392 by the server. Only Client ID and mode lists are sent in the USERS
7393 command. Changed this also to the protocol specification.
7395 The client now resolves the names and stuff after it receives
7396 the USERS list from the server when joining to the channel.
7398 * WHOIS and IDENTIFY commands has been changed to support multiple
7399 Client ID's per command. One can now search for multiple users
7400 in the network by sending only one WHOIS or IDENTIFY command.
7401 Changed the code and the protocol specifications.
7403 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7404 uses silc_server_command_whois_parse to parse the request. */
7406 * If normal server, do not parse the WHOIS and IDENTIFY requests
7407 before sending it to the router. Saves some time.
7409 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7411 * Fixed JOIN command on client library. Wrong number of arguments
7412 used to crash the client.
7414 * Added silc_server_channel_has_global function to check whether
7415 channel has global users or not.
7417 * Added silc_server_channel_has_local function to check whether channel
7418 has locally connected clients on the channel.
7420 * The silc_server_remove_from_one_channel now checks whether the
7421 channel has global users or not after given client was removed from
7422 the channel. It also checks whether the channel has local clients
7423 on the channel anymore. If it does not have then the channel entry
7424 is removed as it is not needed anymore.
7426 * The silc_server_notify now checks on JOIN notify whether the joining
7427 client is one of locally connected or global. If it is global then
7428 the channel has now global users on the channel and that is marked
7429 to the channel entry. Also, it now saves the global client to
7430 global list who is joining and JOINs it to the channel. This is
7431 for normal server, that is.
7433 Changed silc_server_send_notify_on_channel,
7434 silc_server_packet_relay_to_channel and
7435 silc_server_packet_send_to_channel check if we are normal server
7436 and client has router set (ie. global client) do not send the
7437 message to that client, as it is already routed to our router.
7439 * Implemented LEAVE notify type handling in silc_server_notify
7442 * Tested LEAVE command in router environment successfully. Tested
7443 with two routers, two servers and two clients.
7447 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7449 * Implemented SIGNOFF notify type handling in silc_server_notify
7452 * silc_server_remove_id now removes the client entry from all channels
7453 it has joined and thusly sends SIGNOFF notify type.
7455 * Rewrote the NAMES list generation in server by removing two excess
7456 loops. The lists are created now inside one loop.
7458 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * silc_server_remove_channel_user checks now also global list
7461 for channel and client.
7463 * silc_server_new_channel_user checks now both local and global
7464 list for channel and client. Fixed a bug in client id decoding.
7465 Used to decode wrong buffer.
7467 * silc_server_channel_message checks now both local and global
7468 list for channel entry.
7470 * Tested channel joining (hence JOIN) in router environment
7471 successfully. Tested with two routers, two servers and two
7474 * Tested channel message sending in router environment successfully.
7476 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7478 * Added silc_server_save_channel_key into server.[ch] to save the
7479 received channel key in Channel Key payload processing. It is
7480 also used in JOIN command reply handling.
7482 Equivalent function silc_client_save_channel_key added into
7483 client.[ch] into client library.
7485 * Changed JOIN command reply to send information whether the channel
7486 was created or not (is existing already) and the channel key
7487 payload. Changed protocol specs accordingly.
7489 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7490 the request was sent by ID and not by nickname. Crashed on
7493 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7496 now correctly save the received data.
7498 * silc_server_free_sock_user_data now notifies routers in the
7499 network about entities leaving the network.
7501 At the same time implemented functions silc_server_remove_id
7502 and silc_server_send_remove_id to receive and send REMOVE_ID
7503 packets. The packet is used to notify routers in the network
7504 about leaving entities. The ID removed will become invalid in
7507 * Added function silc_idlist_del_server into server. Removes and
7508 free's server entry from ID list.
7510 * silc_server_private_message function now checks, if we are router,
7511 that the destination ID really is valid ID, naturally.
7513 * In router when NEW_ID packet is received (for new client) the
7514 hash of the Client ID is saved in the ID Cache but the
7515 client->nickname is set to NULL, instead of putting the hash
7518 IDENTIFY command now also checks that client->nickname must be
7519 valid. If it is not if will request the data from the server who
7520 owns the client. Added new function
7521 silc_server_command_identify_check.
7523 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7524 to set the command to already allocated Command Payload.
7526 * Tested private message sending in router environment with two
7527 routers, two servers and two clients. Fixed minor bugs and now
7530 * Fixed segfault from client's NAMES command. Used to crash if
7533 * Forwarded packets must not be routed even if it is not destined
7534 to the receiver. Changed server code comply with this.
7536 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Added `require_reverse_mapping' boolean value to ServerParams
7539 structure. If TRUE (not default) the server will require that
7540 the connecting host has fully qualified domain name.
7542 If the reverse mapping is not required and hostname could not be
7543 found the IP address is used as hostname.
7545 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Implemented version string checking to both client and server.
7548 The check is incomplete currently due to the abnormal version
7549 strings used in development version of SILC.
7551 * Changed all command functions in server to use the new
7554 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Changed char *data to unsigned char *data in ID Cache system to
7557 support binary data as ID Cache data. Changed code to support
7558 binary data in lib/silccore/idcache.c.
7560 * Renamed silc_server_packet_relay_command_reply to
7561 silc_server_command_reply as it is normal packet receiving
7562 function. Rewrote the function to accept command replys for
7563 servers and not only for clients.
7565 * Mark remote router always as registered server if we are connecting
7566 to it. Otherwise, commands sent by the router to us are ignored.
7568 * All ID List find routines now returns the ID Cache Entry pointer
7569 as well if requested.
7571 * WHOIS command works now in router environment, tested with two
7572 routers, two servers and two clients.
7574 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7575 in router environment (as it is almost equivalent to WHOIS) but
7576 hasn't been tested thoroughly. Added new functions:
7578 silc_server_command_identify_parse
7579 silc_server_command_identify_send_reply
7580 silc_server_command_identify_from_client
7581 silc_server_command_identify_from_server
7583 * Disabled route cache adding because adding two different ID's with
7584 same IP replaces the old cache entry thus giving wrong route.
7585 The entry->router->connection is always the fastest route anyway
7586 so route cache may not be needed. Of course, new routes maybe
7587 established after receiving the ID when the entry->router->connection
7588 might not be anymore the most optimal.
7590 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Add route cache for received ID for fast routing.
7594 * Added silc_server_packet_route to route received packet on router
7595 that is not destined to us.
7597 * Renamed silc_server_get_route to silc_server_route_get.
7599 * Added id_string and id_string_len fields into SilcServer to
7600 include encoded ServerID for fast comparing without excess
7601 encoding of the ID's.
7603 * Cleaned up WHOIS command on server side. Added following static
7606 silc_server_command_whois_parse
7607 silc_server_command_whois_check
7608 silc_server_command_whois_send_reply
7609 silc_server_command_whois_from_client
7610 silc_server_command_whois_from_server
7612 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7613 arguments in command replies. All command functions should be
7614 updated to use this macro.
7616 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Minor typo fixes on command reply handling on server.
7620 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Added silc_server_command_add_to_channel internal routine to add
7623 the client to the channel after router has created the channel and
7624 sent command reply to the server.
7626 * Added generic silc_server_send_command to send any command from
7629 * Use static buffer with ID rendering instead of duplicating data.
7631 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7633 * Fixed a channel user mode bug when joining to a channel server gave
7634 everybody channel founder rights, oops.
7636 * We mark ourselves as the router of the incoming server connection
7637 if we are router ourselves. This way we can check in some packet
7638 sending functions whether it is locally connected server. For
7639 incoming router connections we put NULL.
7641 * For router sending packets locally means now always sending the
7642 packet cell wide; to local clients and local servers. For normal
7643 server sending packet locally means sending it to only local
7646 * Fixed the JOIN command to really work in router environment. If the
7647 channel is created it is always created by the router. Router is
7648 also responsible of making the initial joining to the channel,
7649 sending JOIN notify to the sending server and distributing
7650 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7651 does not exist server doesn't do anything else but forward the
7652 command to the router which performs everything.
7654 * Added silc_server_send_channel_key function to send the Channel Key
7657 * Added silc_server_create_channel_key to create new channel key. The
7658 channel key is now re-generated everytime someone joins or leaves
7659 a channel, as protocol dictates. Note: channel->key_len is the
7662 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7664 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7665 packet_receive.[ch] to separate packet sending and receiving
7666 routines. The server.[ch] now includes everything else including
7667 actual packet processing (writing and reading data) and other
7670 Renamed silc_server_private_message_send_internal to
7671 silc_server_send_private_message. The routine is still though
7672 used only to relay private messages as server does not send
7673 private messages itself.
7675 Renamed silc_server_new_channel to silc_server_create_new_channel
7676 and added new function sicl_server_new_channel that handles the
7677 incoming New Channel packet. Added also new sending function
7678 silc_server_send_new_channel to send New Channel Payload.
7680 * Added new function silc_server_notify to process incoming notify
7681 packet to the server/router. Server may then relay the notify
7682 to clients if needed.
7684 * Added new function silc_server_new_channel_user to process incoming
7685 New Channel User packet. Router will redistribute the packet and
7686 send JOIN notify to its local clients and locally connected servers
7687 if needed. Normal server will send JOIN notify to its local client
7688 on same channel when received this packet. Added also corresponding
7689 sending function silc_server_send_new_channel_user to sent the
7692 * Added boolean route argument to send_notif_to_channel and
7693 packet_send_to_channel functions to attempt to route the packet
7694 if it is TRUE and send only locally if it is FALSE.
7696 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7698 * silc_server_replace_id now broadcasts the received replace ID
7699 packet if it is not broadcast packet already. The router must
7700 broadcast to inform other routers about changed ID.
7702 * Added backpointer to server's router into SilcServer context in
7703 silcd/server_internal.h.
7705 * Fixed silc_server_packet_broadcast to send correct broadcast
7708 * The channel key is now distributed to the local client as soon
7709 as it is received from the router (in router environment) so that
7710 no other packet may be sent for the channel until client has
7713 * silc_server_remove_channel_user now broadcasts the received
7714 Remove Channel User packet if it is not broadcast packet already.
7715 The router must broadcast to inform other routers about removed
7718 * Added users field into SilcPacketContext that is a reference count
7719 of the context. One can increase the reference count by calling
7720 silc_packet_context_dup which is now changed to just increase the
7721 reference count instead of duplicating the data. The reference
7722 count is decresed by calling silc_packet_context_free that will
7723 free the data after the reference count hits zero.
7725 For now on the packet context and everything allocated into it
7726 (including the raw packet from network) must be freed by calling
7727 the new silc_packet_context_free function. Added also new function
7728 silc_packet_context_alloc that must be used now to allocate the
7729 context. This also means that if a routine is asynchronous from
7730 silc_[client/server]_packet_parse_type the packet context must
7731 be duplicated by calling silc_packet_context_dup. Otherwise it
7732 gets free'd after silc_[client/server]_packet_parse_type returns.
7733 Also, one must remember that if packet is duplicated then its
7734 reference count must be decresed by calling the free function as
7735 many times as it was duplicated.
7737 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7738 from both client and server.
7740 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Made joining to a channel working in router environment.
7744 * Cleaned up JOIN command on server side and create function
7745 silc_server_command_join_channel internal routine to make the
7748 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Changed silc_command_pending list to SilcDList. Also, added
7751 `ident' field to SilcServerCommandPending structure to identify
7752 the reply and to call correct callback.
7754 Added silc_server_command_pending_check function to replace the
7755 corresnponding macro. The silc_command_pending list is not
7758 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7759 to set identifier to previously allocated Command Payload. It
7760 is used to set identifier for command when resending Command
7763 * Added silc_command_payload_encode_payload to encode Command
7764 Payload buffer from SilcCommandPayload structure.
7766 * Added silc_argument_payload_encode_payload to encode Argument
7767 payload buffer from SilcArgumentPayload structure.
7769 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Changed WHOIS command to support router connection on server side.
7772 The whois request is always sent to router unless the server is
7773 standalone server. After server has received the reply from the
7774 router will it send the reply to the client.
7776 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7777 broadcast received broadcast packet. The function is used only
7778 by router. The broadcast packet is always sent to the router's
7781 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7782 render given ID to printable string, for log files for example.
7784 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7786 * Made basic router to router connections working. At least they
7787 can now connect to each other but nothing really works the way
7788 they are supposed - yet.
7790 * Added new initiator token to RouterConnection configuration
7791 file in silcd/serverconfig.[ch]. It is used to tell whether we
7792 are the initiator to the remote router or whether we'll expect
7793 the other end to connect.
7795 * Moved registering of listener task to silc_server_init, hence
7796 the server starts listenning as soon as it is run, even if it
7797 does not have connections to other routers. Let's see how well
7800 * Changed default connection retry timeouts for more suitable in
7803 * Removed cipher and such arguments from silc_idlist_add_client
7804 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7805 Added new function silc_idlist_add_data to add the keys and stuff
7808 * Added SilcIDListData structure and added it to SilcClientEntry
7809 and SilcServerEntry as their first field in the structure. This
7810 way we can explicitly cast the ID entries to the SilcIDListData
7811 structure and get common data for the entries. In past, we had
7812 to first check what type of connection it is and then cast it to
7813 correct ID entry type. Now, we can directly cast the opaque
7814 pointer to the SilcIDListData (no matter what ID entry it actually
7815 is) and get the data needed.
7817 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7820 in some circumstances even if threre were timeout tasks, though not
7821 IO tasks, but tasks anyway. Now fixed.
7823 * Defined SilcServerConnection structure to hold connection specific
7824 stuff about directly connected servers and routers. The definition
7825 is currently in silcd/server_internal.h. I thought about having
7826 a bit more important role fro this struct but for now it is used
7827 only when connecting to other server (or router actually).
7829 * Added connecting retry support in server when connecting to
7830 router(s). The retry feature implement exponential backoff
7831 algorithm. Also, added SilcServerParams structure to hold default
7832 parameters for server. For now, it include these retry settings
7833 and are hard coded. After server is moded to be as Silc Server
7834 Library this structure will be more important.
7836 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7838 * Changed client librarys channel->clients table to SilcList and
7839 changed code accordingly.
7841 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7843 * Changed client's channel table to SilcList and changed code
7844 accordingly. Also changed SilcChannelClientEntry to include back-
7845 pointer to the channel so that client entry can use that structure
7846 as list as well and we have fast cross-reference to the channel.
7847 This change dramatically decreased the complexity of channel
7848 handling with client entry and vice versa (removed one extra
7849 loop when searching for channel entry from many functions).
7851 * Changed server->sim from table to SilcDList and changed code
7854 * NAMES command can now be used from user interface. It will show
7855 the user list on the channel, neatly.
7857 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7858 Code now saves realname of the user if it becomes available.
7860 * Renamed configure.in to configure.in.pre and made ./prepare
7861 script to automatically add correct version string to
7862 configure.in which it creates from configure.in.pre.
7864 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7866 * NAMES command reply now shows users mode with the nickname when
7869 * Moved silc_client_ch[u]mode[_char] functions from
7870 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7871 place sucks, they are utility functions and should be in some
7874 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7876 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7879 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Added TRQ (efficient deque and list library) into lib/trq. This is
7884 a very good list library that is currently used in the SILC. Defined
7885 SilcList API over the library because I didn't like the API very
7886 much. See lib/trq/silclist.h for the API and examples of how to
7887 use the API. Fixed various places in the code to use the new
7888 SilcList API. The SilcList is meant for lists that has a structure
7889 already defined as a list. It is not suitable to add just some
7890 context to the list (in TRQ, the context is the list actually).
7892 So, I defined SilcDList that can be used for the purpose where
7893 predefined list structure does not exit. This can be used as
7894 such list. Now some context just can be added to the SilcDList.
7895 Currently this list is not used in the SILC just yet, though there
7896 are a lot places where this can replace dynamically allocated
7897 tables and I will fix these places, later, to use SilcDList.
7898 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7899 and use TRQ internally).
7901 Also fixed some annoying warning messages that the original TRQ
7902 code generated. Also minor changes to TRQ's Makefile.in.
7904 * Added support for querying by Client ID to both WHOIS and
7905 IDENTIFY commands into server, as required by the protocol.
7907 * Removed method function pointers from SilcBuffer structure. They
7908 weren't used to anything and just increased the context size for
7909 no good reason. This change also made silc_buffer_alloc and
7910 silc_buffer_free functions inline functions.
7912 * Disabled command flooding detection support until it's fixed so
7913 that it accepts commands in but does not execute them more than once
7916 * Added silc_net_localhost(), to return local hostname, into
7917 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7918 that must be initialized before calling silc_client_init.
7920 * Added new function: silc_server_send_notify_on_channels to send
7921 notify messages to all channels client has joined. It is assured
7922 that the message is sent only once per client.
7924 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7925 lib/silcutil/silcutil.[ch] as silc_format function. The new
7926 function is generic and is used by server as well, not only by
7927 the logging routines.
7929 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7930 the provided version string was not acceptable. Added new function:
7931 silc_ske_check_version into lib/silcske/silcske.h. The function
7932 must be implemented by the application (client or server) and it
7933 does not reside in the SKE library. The function checks the version
7934 string remote end sent.
7936 * Added back pointers (to opaque context and to SilcSocketConnection)
7937 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7939 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7940 duplicate packet context structure.
7942 * Changed `notify' client operation to send same arguments as client
7943 receives from server except for ID's. ID's are mapped to correct
7944 ID entry and that is returned. Also, if channel entry is not sent
7945 by server but the notify is for channel the channel entry is sent
7946 to application (otherwise application doesn't know that it is for
7947 channel (library gets it from packet's Destination ID)).
7949 * Added silc_client_remove_from_channels into client library to
7950 remove a client from all channels it has joined to. Used when
7951 received SIGNOFF notify from server. Added also new function
7952 silc_client_replace_from_channels to replace old ID entry with
7953 new ID entry on all channels. Used when received NICK_CHANGE
7956 * Fixed ID Cache list handling in silc_idlist_get_client in
7957 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7958 to get (or query) client by ID.
7960 * Updated TODO list.
7962 * Added connection authentication status message defined by the
7963 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7964 support for these into the code in client and server side.
7966 * Added generic function silc_client_send_command to send any command
7967 with variable argument list. Application should use this function
7968 to send commands if the command functions provided by the library
7969 does not suite for the application's user interface needs.
7971 * Added new `failure' client operation. Application is notified about
7972 received failure packet if client is executing a protocol. In this
7973 case the protocol's execution has failed.
7975 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7976 is required by the protocol.
7978 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7979 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7982 * Added status flag to SilcSKE object to indicate realtime status
7983 of the SKE protocol.
7985 * Application receives now exactly same command reply arguments as
7986 the library receives from server. However, if ID is received the
7987 corresponding ID entry is returned to the application (eg. Client
7988 ID is mapped to correct SilcClientEntry entry and that is returned).
7989 Changed command_reply client operation due to this change.
7991 * Changed all ID's in commands and in command replys as ID Payloads.
7992 Change affected both client and server side codes.
7994 All ID's sent in SILC network (with execption of ID's in SILC
7995 Packet header) are sent in ID Payload to support variable length
7998 * Server now notifies nick changes and notifies all clients on
7999 the channels about the new nickname (about the new Client ID,
8002 * Implemented CMODE command to change channel modes. Supports all
8003 channel modes defined by the protocol specs except ban and invite
8004 lists. (Also, private channel key mode is supported but support for
8005 setting private channel key in client is missing, thus, this mode
8006 has no effect on client side (except that server requires that the
8007 client uses private channel key and normal channel traffic does not
8010 Also, invite mode works per se, but INVITE command does not work
8011 yet correctly, so you can set channel as invite only channel but
8012 inviting clients to the channel does not work (it is yet to be
8013 thought what's the best way to do it).
8015 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8016 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8017 Implemented CUMODE command to change user's mode on the channel.
8018 Supports all modes defined by the protocol specs.
8020 * Added NAMES command reply to return users modes on the channel.
8022 * Removed unnecessary and slow ciphers from lib/silccrypt.
8024 * Set SO_KEEPALIVE option to connection sockets by default.
8026 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8028 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8029 redefined the Notify Payload into protocol specs.
8031 * Added silc_id_payload_parse_id to get ID directly from raw
8034 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8037 accept searching by Client ID as well.
8039 * Added support for LEAVE and SIGNOFF notify types in client library.
8041 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8042 to parse ID Payload from raw data.
8044 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Added flags parameter into silc_ske_assemble_security_properties
8047 function in lib/silcske/silcske.[ch].
8049 * Changed notify client operation to fit better for notify messages
8050 sent by server. The notify payload received from server is now
8051 passed to the application (after parsing it to SilcNotifyPayload).
8052 It is application's responsibility to retrieve the arguments
8053 from the payload and show the message the way it wants. The message
8054 sent by server is implementation specific.
8056 * Changed public keys to comply with the protocol specification.
8057 Old public keys are not supported anymore and are not compatible.
8059 * Removed nickname from Channel Payload as the latest draft removed
8060 it. The client must resolve the nickname from the NAMES command
8061 reply received when it joined the channel.
8063 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8065 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Fixed some errors in protocol specification drafts.
8069 * Created lib/silccore/silcnotify.c to implement Notify Payload
8070 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8071 generic payloads described by protocol specifications. The file
8072 includes implementations for ID Payload and Argument Payload.
8074 * Changed Command Payload implementation to use the new Argument
8075 Payload. Changed command_xxxx_payload to command_payload_xxxx
8076 to comply with SILC coding conventions.
8078 * Added suppport for Argument Payload handling in Notify Payload
8079 implementation as protocol requires it. Added the new support
8080 into server and client lib as well.
8082 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Added support for multiple nicknames on same channel. [n] is
8085 added locally to the nickname if there are more than one same
8086 nicknames on the channel.
8088 * Server now sends all nicknames that matched WHOIS request.
8089 Client also shows the list received from server.
8091 * Added TOPIC command to client side. User can now set and show
8092 current topic on channel.
8094 * Added MOTD command to client and server. Also, server sends the
8095 motd when client connects to the server.
8097 * Changed version strings to comply ISO 8601.
8099 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8101 * Fixed protocol error handling in client library. It should now
8102 cope even if the SKE fails for some reason.
8104 * Made new protocol specification drafts for submitting to IETF.
8106 * Implemented TOPIC command to server in silcd/command.c.
8108 * Added two new notify types into lib/silccore/silcnotify.h:
8109 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8110 notify nickname change and topic setting/change on a channel.
8112 * API change of command_reply operation in client library. The
8113 application gets now the status type received from server as well.
8115 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8117 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8119 * Cras fixed and optimized the packet handling even further and
8120 it should work now. Minor change to the prototype of function
8121 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8123 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Added new function into lib/silcutil/silcschedule.[ch]:
8126 silc_schedule_with_fd to select() a specified fd. The function
8127 returns after timeout expires or data arrives or goes. The
8128 function is used by packet routines to wait that all data is
8129 received from network.
8131 * Fixed data reading from network in lib/silccore/silcpacket.c.
8132 The code now assures that all data is read from the fd and then
8133 continues packet processing. This was a bug fix since the code
8134 used to drop some data in some circumstances.
8136 * Added new function into lib/silcclient/client.[ch]:
8137 silc_client_start_key_exchange to start key exchange after
8138 connection has been established to server. The code internally
8139 now uses this funtion but its main purpose was to provide it
8140 for applications that perform their own connecting. After
8141 application has created a connection it merely calls this
8142 function to start the key exchange between client and server.
8143 The library takes care of everything else after that.
8145 Updated also lib/silcclient/README to explain the usage of
8148 * Do not send to application information that connection has
8149 been established. Application gets notified it by connect
8152 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8154 * Applied cras's patch to add silc_schedule_one function. The
8155 function runs scheduler once and returns.
8157 * Fixed the scheduler after cras messed it up. The timeout
8158 handling works now as it's supposed to work.
8160 * Added into lib/silccore/ silcnotify.h to include notify
8161 message types support. Changed silc_server_send_notify*
8162 functions, in server.[ch], to support those new notify types.
8163 Added the support for the notify types into client library,
8164 as well. Added new notify client operation into ops.h in
8167 * Changed silc_server_packet_send_to_channel to send normal
8168 packets instead of just channel message packets. The function
8169 is now used to send the notify packets to channels. It is not
8170 used to send channel message packets anymore, as server never
8173 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8174 va_arg()s as it seems to require it nowadays. I guess, if SILC
8175 is compiled with older va_arg() the new code should work anyway.
8177 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8179 * Splitted core library. Core library (lib/silccore) includes
8180 now only SILC protocol specific core (and common) components.
8181 Created new utility library (lib/silcutil) that includes more
8182 generic purpose stuff. The stuff for util library was taken
8183 from the old core library. This was minor and easy split.
8185 * Created SILC Client Library (lib/silcclient) that includes
8186 implementation of the SILC client without user interface. This
8187 was major move from silc/ directory. The code has been changed
8188 so that it is transparent towards the user interface. The
8189 silc/ directory includes now the same user interface as before
8190 and it uses the new client library. Read lib/silcclient/README.
8191 Basicly, the client library performs everything else related
8192 to SILC except user interface handling. Also, configuration
8193 files are considered to be part of user interface and library
8194 does not handle them.
8196 This change also changed a lot of structures, function naming etc.
8197 Most important change was that SilcClientWindow object was
8198 renamed to SilcClientConnection in the client library. Created
8199 also new file lib/silcclient/ops.h. Also added new files
8200 silc/local_command.[ch] and silc/client_ops.[ch].
8202 All these changes were made to make it easier for user interface
8203 designers to create what ever user interface for the SILC client
8206 It is also expected that the server will be moved to lib
8207 directory as well and SILC Server Library will be created;
8208 sometimes in the future.
8210 * Removed Local commands from lib/silccore/silccommand.h as
8211 they are application specific and new client library does not
8212 handle any of those anymore.
8214 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8215 old client implementation in silc/.
8217 * Added support for callback functions in SILC_LOG_* macros.
8218 Application can now set its own callbacks that will be called
8219 instead of using the default functions that will always print
8220 the debug messages to stderr (or stdout). Also, debugging can
8221 now be disabled by setting silc_debug to FALSE and re-enabled by
8222 setting it to TRUE. Note, that logging will still work even
8223 if debugging is disabled.
8225 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8226 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8227 silc_log_reset_debug_callbacks.
8229 * To enable debugging in silc client one must give now -d
8230 option on command line.
8232 * Changed silc_schedule_init to automatically allocate task queues
8233 if they are not allocated before calling it.
8235 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8237 * Added GMP 3.1 into math library.
8239 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8241 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8242 a channel in SILC network. The packet is used by servers and
8243 routers to notify other routers that user has left a channel.
8244 This little feature was missing until now. Added the feature
8245 to protocol specification as well.
8247 Added functions: silc_server_send_remove_channel_user and
8248 silc_server_remove_channel_user into server.[ch].
8250 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8251 lib/silccore/silcpacket.h. However, they are not implemented
8254 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Fixed joining to a channel and sending channel messages
8257 between server and router. The channel message sending should
8258 now work inside a cell.
8260 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8262 * Fixed the private message sending between server and router.
8263 The private message sending should now work inside a cell.
8265 * Added silc_server_replace_id into server.[ch] to replace
8266 existing ID in the SILC network.
8268 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8269 and silc_idlist_replace_server_id into idlist.[ch] in server.
8271 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8273 * Fixed the server to server connections. Server can again now
8274 connect to router. Router to router connections probably does
8277 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8279 * Added dynamic protocol registering support. Now protocols can
8280 registered and unregistered on the fly. Patch by cras.
8282 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8284 * Added lib/contrib directory to hold routines that some platforms
8285 don't have but are needed by SILC.
8287 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8288 into lin/contrib to provide getopt() and getopt_long() for
8289 those who don't have it.
8291 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Added AWAY command to client. When away message is set and
8294 client receives a private message packet the client automatically
8295 replies to the sender with the away message.
8297 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8298 bug seemed to be the cause of recent problems when compiling
8301 * Added version detection support to SKE protocol specification
8302 and added the new changes to the SKE implementation as well.
8303 There were other minor changes in the SKE protocol as well.
8305 Many changes in lib/silcske/silcske.[ch] and in
8306 lib/silcske/payload.[ch].
8308 * Added ^U functionality, clear input line. Patch from cras.
8310 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8312 * Mainly small bugfixes on core library. Fixed some debugging
8313 logging and buffer overflow in silclog.c.
8315 * Updated config.sub and config.guess on the distribution tree.
8317 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8319 * Added command lagging support in server. Client may execute
8320 commands now only once in two seconds.
8322 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8324 * Optimized packet reception. MAC computation and checking is now
8325 also more optimized. A lot previously duplicated code is now
8326 used as generic by both client and server.
8328 * Fixed key pair generation in clientutil.c
8330 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Added into lib/silccore/silcbufutil.[ch] new function;
8333 silc_buffer_realloc.
8335 * Moved generic packet sending/encryption functions to
8336 lib/silccore/silcpacket.[ch] from client and server. Some
8337 rewriting of the functions.
8339 * Moved all generic packet reception/decryption functions to
8340 lib/silccore/silcpacket.[ch] from client and server. The
8341 packet processing is now much cleaner in both client and server.
8342 These were major changes in both client and server.
8344 * Created many common functions in server to do packet sending.
8345 Previously code were duplicated a lot, this has been removed
8348 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8350 * Rewrote major parts of the ID cache system. Don't know
8351 whether it is better now or not but at least the API is more
8354 * Major rewrite on ID cache stuff on client because of the ID
8355 cache API changes. Added idlist.c to client.
8357 * Also major rewrite on ID cache stuff on server as well.
8358 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8359 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8360 in hand, instead they are all put into the ID cache system now.
8361 All server_idlist_* routines uses ID cache now instead of
8362 traversing its own lists (those lists does not exist anymore).
8363 SilcIDList though still exists. Also, SilcXXXEntry's are
8366 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8368 * Finally made the SKE implementation compliant to the protocol
8369 specification. All mp integers are now binary encoded as
8370 opposed being HEX encoded.
8372 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8375 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8376 functions: silc_[encode/decode]_pem. Also added function
8377 silc_encode_pem_file to PEM encode with newlines ('\n') for
8380 * SILC public keys are now encoded either PEM or binary. Same
8381 option is for private keys as well. By default private keys
8382 are binary encoded and public keys PEM encoded. Silly HEX
8383 encoding were removed.
8385 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8386 function to create fingerprints.
8388 * Fixed a bug in SHA1; does not change the original data anymore.
8390 * Partly implemented INFO command on client and server side.
8391 Fixed CLEAR command. Changes to SERVER command; show current
8392 server(s) when giving command without arguments. Added
8393 VERSION command to client.
8395 * Added check to server that unregistered connections cannot
8396 execute commands (unless it is specificly allowed).
8398 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Fixed screen refresh.
8402 * Fixed channel joining bug from client. On some circumstances
8403 client tried to join to a channel it had already joined.
8405 * Added public key verification process into client's protocol.c.
8406 The client now verifies the public key from user and saves
8407 it into ~./silc/serverkeys/ directory.
8409 Added into: clientutil.[ch]: silc_client_verify_server_key.
8411 * Changed SKE protocol's silc_ske_initiator_finish function
8412 to accept callback function that verifies the received public
8413 key. Removed old silc_ske_verify_public_key function.
8415 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8417 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8418 silc_pkcs_private_key[_data]_set.
8420 * Made the password and public authentication more cleaner in
8421 server's protocol.c.
8423 * Removed historic and obsolete protocol `channel_auth' from
8424 both client and server.
8426 * Removed wrong way of sending command status messages from
8427 server to client in server's command.c. The old way violated
8428 protocol specification.
8430 Changes to silccore/silccommand.[ch]: removed
8431 silc_command_encode_status_payload -> not needed anymore,
8432 changed silc_command_encode_payload_va to accept extra
8433 argument on variable argument list. The argument type must
8434 now be provided to the function. Also, added new function:
8435 silc_command_encode_reply_payload_va which is same as
8436 normal command_encode_payload_va except command status type
8437 is provided as extra argument.
8439 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8441 * Added ~./silc directory handling. The directory includes the
8442 public and private keys for the client.
8444 Added silc_client_check_silc_dir, silc_client_create_identifier
8445 and silc_client_load_keys.
8447 * Implemented SILC protocol compliant public key. Added public
8448 and private key saving to and loading from files.
8450 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8451 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8452 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8453 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8454 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8456 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8457 silc_pkcs_load_[public/private]_key.
8459 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8461 * Added silc_server_get_route (route.[ch]) to get connection
8462 data for the fastest route for given ID.
8464 * Implemented INVITE command on client and server. The command
8465 were re-defined in the SILC Protocol Specification and the
8466 implementation now complies with the specification.
8468 * Implemented PING command on client and server.
8470 * Implemented NAMES command on client and server. The server side
8471 supports currently only normal server not router server yet.
8472 Some changes to NAMES definition in SILC protocol specification.
8474 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8476 * Implemented LEAVE command on client and server.
8478 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8479 again. This change was made to the protocol as well. Server
8480 should not violate the protocol specification anymore.
8482 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8485 was tested. SOCKS4 was not but should work anyway.
